hereof, this Agreement shall not constitute nor require an assignment to Spinco

Liabilities under this Agreement.

         4.2 As soon as administratively possible after the Distribution Date,
Spinco shall establish a defined contribution plan (the "Spinco 401(k) Plan")
which shall be qualified under Section 401(a) of the Internal Revenue Code of
1986, as amended, and effective as of the Distribution Date. As soon as
administratively feasible following the Distribution Date, and in accordance
with the terms of the GulfMark 401(k) Plan, GulfMark shall cause the account
balance attributable to each individual who will cease to be an employee of
GulfMark following the Distribution Date to be distributed directly to such
individual, or upon the request of any such individual, transferred to another
qualified rollover investment (including the Spinco 401(k) Plan if such
individual is eligible to participate therein) specified in such request to the
extent that such transfer or distribution is permitted by law. Each individual
who becomes an employee of Spinco on the Distribution Date shall, for
eligibility and vesting purposes under the Spinco 401(k) Plan, be credited with
the same service with which he or she is credited for such purposes under the
GulfMark 401(k) Plan immediately prior to the Distribution Date.

         4.3  Employee Health, Life and Disability Insurance Plans.  Effective
as of the Distribution Date, Spinco shall establish such employee health, 
life and disability insurance plans and other employee welfare or fringe 
benefit arrangements (collectively the "Spinco Employee

                                     - 12 -

<PAGE>   14



Benefit Plans") which are comparable in the aggregate to the health, life and
disability insurance plans and other employee welfare or fringe benefit
arrangements which had been maintained by GulfMark for its employees and the
employees of its Subsidiaries prior to the Distribution Date (collectively the
"GulfMark Employee Benefit Plans"). Service by any employee with GulfMark or its
Subsidiaries prior to the Distribution Date shall be counted for purposes of
determining any period of eligibility to participate in, or to vest in benefits
(including vacation rights) provided under, the Spinco Employee Benefit Plans,
and any amounts previously expended by any such employees of GulfMark or its
Subsidiaries prior to the Distribution Date for purposes of satisfying such plan
year's deductible, co-payment limitations maximum out-of-pocket provisions and
applicable annual and/or life-time maximum benefit limitations shall be credited
for purposes of satisfying such plan year's deductible, co-payment limitations
under the Spinco Employee Benefit Plans and any coverage waiting period for
pre-existing conditions for such employees shall be waived under the Spinco
Employee Benefit Plans.

                                    ARTICLE V

                           GULFMARK STOCK OPTION PLANS

         5.1 As of the Distribution Date, Spinco shall assume the GulfMark Stock
Option Plans, and pursuant to the equitable adjustment provisions of the
applicable Stock Option Plan, each outstanding stock option previously granted
pursuant to any of GulfMark's Stock Option Plans to an employee, officer or
director of GulfMark who will, following the Distribution, become an employee,
officer or director of Spinco, will be converted into and represent an option to
acquire shares of Spinco Common Stock.

         5.2 The number of shares of Spinco Common Stock subject to, and the
exercise price of, each such Spinco option will be adjusted in accordance with
the requirements of Section 424 of the Internal Revenue Code of 1986, as
amended, and the regulations promulgated thereunder, to reflect the Distribution
as set forth in Section 5.3 so that (i) the aggregate intrinsic value
(difference between market value per share and exercise price) of each option
immediately after the Distribution is not greater than the aggregate intrinsic
value of such option immediately before the Distribution, and (ii) the ratio of
the exercise price per option to the market value per share is not reduced. The
vesting provisions and option period of the new Spinco options will remain
unchanged from the GulfMark options so replaced.

         5.3 As of the Distribution Date, to effect the adjustment described in
Section 5.2, (i) the number of shares of Spinco Common Stock covered by each new
Spinco option shall be the number of shares covered by the GulfMark option being
replaced thereby, multiplied by a fraction equal to the ratio of the
pre-Distribution market price per share of GulfMark Common Stock to the
post-Distribution market price per share of Spinco Common Stock, and (ii) the
exercise price per share of each new Spinco option shall be the exercise price
per share of the GulfMark option being replaced thereby, multiplied by a
fraction equal to the ratio of the post- Distribution market price per share of
the Spinco Common Stock to the pre-Distribution market price per share of
GulfMark Common Stock.

<PAGE>   15



         5.4 For purposes of the foregoing adjustments, (i) the pre-Distribution
market price per Share of GulfMark Common Stock shall be deemed to be the
average of the arithmetic mean between the highest and lowest sales prices per
share of GulfMark Common Stock as reported by the NASDAQ Stock Market on each of
the ten trading days before the Distribution or such other market price as the
Board of Directors of Spinco deems equitable, and (ii) the post- Distribution
market price per share of Spinco Common Stock shall be deemed to be the average
of the arithmetic mean between the highest and lowest sales prices per share of
Spinco Common Stock as reported by the NASDAQ Stock Market on each of the ten
trading days beginning on the eleventh trading day after the Distribution or
such other market price as the Board of Directors of Spinco deems equitable.

         5.5 GulfMark and Spinco will cooperate and take all action necessary
(including obtaining the consent of the holders of GulfMark options, if
required) to amend (if necessary) the GulfMark Stock Option Plans or otherwise
provide for adjustments of authorized shares and outstanding option awards under
the GulfMark Stock Option Plans, and to effect Spinco's assumption of the
GulfMark Stock Option Plans, in accordance with the provisions of this Article
V.

                           (xvi)any and all Environmental Conditions, known or

                  relating thereto; and

                           (xix) any Liability relating to the GulfMark 401(k)
                  Plan and the other employee benefit or welfare plans of
                  GulfMark or any GulfMark Company arising out of circumstances
                  occurring on or prior to the Effective Date.

                  (b) Absolute Indemnity. NONE OF THE EVI INDEMNIFIED PARTIES
        WILL BE OBLIGATED TO INSTITUTE ANY LEGAL PROCEEDINGS IN CONNECTION WITH
        THE COLLECTION OR PURSUIT OF ANY INSURANCE IN ORDER TO EXERCISE AN
        INDEMNIFICATION REMEDY UNDER THIS ARTICLE VI. UNLESS OTHERWISE
        SPECIFICALLY EXPRESSED, THIS INDEMNITY OBLIGATION SHALL APPLY WITHOUT
        REGARD TO WHETHER THE LIABILITY OR ENVIRONMENTAL LIABILITY WAS CAUSED BY
        THE ORDINARY OR GROSS NEGLIGENCE OF ANY OF THE EVI INDEMNIFIED PARTIES
        (WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT OR ACTIVE OR
        PASSIVE), OR WHETHER THE LIABILITY OR ENVIRONMENTAL LIABILITY IS BASED
        ON STRICT LIABILITY, ABSOLUTE LIABILITY OR ARISES AS AN OBLIGATION OF
        CONTRIBUTION OR INDEMNITY. SPINCO ACKNOWLEDGES THAT IT IS AWARE OF
        VARIOUS THEORIES KNOWN AS THE "EXPRESS NEGLIGENCE" DOCTRINE AND OTHER
        SIMILAR DOCTRINES AND THEORIES THAT MAY LIMIT INDEMNIFICATION AND AGREES
        AND STIPULATES THAT THE PROVISIONS OF THIS AGREEMENT REFLECT THE EXPRESS
        INTENT OF THE PARTIES THAT THE INDEMNIFICATION TO BE PROVIDED BY SPINCO
        APPLY NOTWITHSTANDING THE FACT THAT THE LIABILITY OR ENVIRONMENTAL
        LIABILITY (I) MAY NOT CURRENTLY BE KNOWN BY IT OR MANIFEST ITSELF IN ANY
        REGARD, (II) MAY ARISE UNDER A STATUTE

                                     - 16 -

<PAGE>   18



        OR THEORY THAT MAY NOT CURRENTLY EXIST OR BE KNOWN TO SPINCO, (III) MAY
        ARISE AS A RESULT OF A NEGLIGENT ACT OR OMISSION BY ANY OF THE EVI
        INDEMNIFIED PARTIES (WHETHER SUCH CONDUCT BE SOLE, JOINT OR CONCURRENT
        OR ACTIVE OR PASSIVE) OR (IV) MAY CONSTITUTE A VIOLATION OF ANY
        APPLICABLE CIVIL OR CRIMINAL LAW OR REGULATION.

        6.2 Notice of Circumstance. After receipt by EVI of notice, or EVI's
actual discovery, of any action, proceeding, claim, demand or potential claim
which could give rise to a right to indemnification pursuant to any provision of
this Agreement (any of which is individually referred to as a "Circumstance"),
EVI shall give Spinco written notice describing the Circumstance in reasonable
detail; provided, however, that no delay by EVI in notifying Spinco shall
relieve Spinco from any Liability or Environmental Liability hereunder unless
(and then solely to the extent) Spinco's position is actually adversely
prejudiced. In the event Spinco notifies EVI within 15 days after such notice
that Spinco is assuming the defense thereof, (i) Spinco will defend the EVI
Indemnified Parties against the Circumstances with counsel of its choice,
provided such counsel is reasonably satisfactory to EVI, (ii) the EVI
Indemnified Parties may retain separate co-counsel at its or their sole cost and
expense (except that Spinco will be responsible for the fees and expenses for
the separate co-counsel to the extent EVI concludes reasonably that the counsel
Spinco has selected has a conflict of interest), (iii) the EVI Indemnified
Parties will not consent to the entry of any judgment or enter into any
settlement with respect to the Circumstances without the written consent of
Spinco and (iv) Spinco will not consent to the entry of any judgment with
respect to the Circumstances, or enter into any settlement which (x) requires
any payments by or continuing obligations of an EVI Indemnified Party, (y)
requires an EVI Indemnified Party to admit any facts or liability that could
reasonably be expected to adversely affect an EVI Indemnified Party in any other
matter or (z) does not include a provision whereby the plaintiff or claimant in
the matter releases the EVI Indemnified Parties from all Liability with respect
thereto, without the written consent of EVI. In the event Spinco does not notify
EVI within 15 days after EVI has given notice of the Circumstance that Spinco is
assuming the defense thereof, the EVI Indemnified Parties may defend against, or
enter into any settlement with respect to, the Circumstance in any manner the
EVI Indemnified Parties reasonably may deem appropriate, at Spinco's sole cost.
The foregoing provisions shall not apply to the provisions of Section 5.7 of the
Merger Agreement.

        6.3 Insurance. Spinco shall not be obligated to indemnify the EVI
Indemnified Parties for amounts which shall have been covered and paid by
insurance of the EVI Indemnified Parties, provided, however, insurance shall not
include deductibles or self-insured retentions.

        6.4 Scope of Indemnification. INDEMNIFICATION UNDER THIS ARTICLE VI
SHALL BE IN ADDITION TO ANY REMEDIES THE GULFMARK, EVI OR ANY EVI INDEMNIFIED
PARTY MAY HAVE AT LAW OR EQUITY. THERE SHALL BE NO TIME LIMIT AS TO SPINCO'S
INDEMNIFICATION OBLIGATIONS HEREUNDER.

        6.5 Indemnity for Certain Environmental Liabilities.  It is the
intention of the parties that the indemnity provided herein with respect to 
Environmental Liabilities under CERCLA and

                                     - 17 -

corresponding provisions of state law is an agreement expressly not barred by 
42 U.S.C. ss. 9607(e)(i) and corresponding provisions of state law.

                                   ARTICLE VII

                         ADDITIONAL COVENANTS OF SPINCO

        7.1 Employment. Spinco shall offer employment or continued employment
from the Contribution Date to all employees of GulfMark, except those employed
by Ercon, on terms that are substantially the same as the terms on which they
were employed by GulfMark immediately prior to the Contribution Date; provided,
however, that nothing contained in this Section 7.1 is intended to confer upon
any employee who so continues to be employed or who accepts such an offer of
employment by Spinco ("Spinco Group Continuing Employees") any right to
continued employment after the Contribution Date. GulfMark hereby consents to
Spinco making such offers. Spinco shall recognize the service with GulfMark
through the Contribution Date of each Spinco Group Continuing Employee and shall
credit on the Contribution Date, such service with Spinco (i) for all plan
purposes under any employee benefit plan, arrangement or policy of the Spinco
Group in effect as of the Contribution Date in which they are then participating
and (ii) for eligibility and vesting purposes only under any employee benefit
plan, arrangement or policy for which they become eligible on or following the
Contribution Date.

        7.2 Spinco Covenants. To assure the performance of the obligations of
Spinco under this Agreement, Spinco hereby covenants and agrees that it will
not, and will cause its Subsidiaries to not, merge, convert into another entity,
engage in a share exchange for a majority of its shares, liquidate or transfer,
assign or otherwise convey or allocate, directly or indirectly, in one or more
transactions, whether or not related, a majority of Spinco's assets (determined
in good faith by a board resolution prior to the transaction on a fair value and
consolidated basis) to any Person unless the acquiring Person expressly assumes
the obligations of Spinco hereunder, (ii) executes and delivers to GulfMark and
EVI an agreement agreeing to be bound by each and every provision of this
Agreement as if it were Spinco and (iii) has a net worth on a pro forma basis
after giving effect to the acquisition or business combination equal to or
greater than that of Spinco (on a consolidated basis).

        7.3 Tax Allocation Agreement. Prior to the Distribution, GulfMark,
Spinco and EVI shall enter into a Tax Allocation Agreement acceptable in all
respects to EVI and Spinco, which will set forth each party's rights and
obligations with respect to payments and refunds, if any, of Taxes for periods
before and after the Effective Date and related matters such as the filing of
tax returns and the conduct of audits and other tax proceedings.

                                  ARTICLE VIII

                                   CONDITIONS

        8.1  Conditions to Obligations of GulfMark.  The obligations of the 
GulfMark to consummate the Distribution hereunder shall be subject to the 
fulfillment of each of the following conditions:

                  (a) All of the transactions contemplated by Article II 
        shall have been consummated.

                  (b) The recapitalization of Spinco in accordance with 
        Section 3.2 shall have been consummated.

                  (c) Each condition to the Closing of the Merger Agreement set
        forth in Article VI thereof, other than conditions as to the
        consummation of the Contribution and the Distribution, shall have been
        fulfilled or waived by the party for whose benefit such condition
        exists.

                  (d) The Board of Directors of GulfMark shall be reasonably
        satisfied that, after giving effect to the Contribution, (i) GulfMark
        will not be insolvent and will not have unreasonably small capital with
        which to engage in its businesses and (ii) the GulfMark surplus would be
        sufficient to permit, without violation of Section 170 of the DGCL, the
        Distribution.

                                   ARTICLE IX

                                  MISCELLANEOUS

        9.1 Governing Law. All questions arising out of this Agreement and the
rights and obligations created herein, or its validity, existence,
interpretation, performance or breach shall be governed by the laws of the State
of Texas, without regard to conflict of laws principles.

        9.2 Arbitration. Any disputes, claims or controversies connected with,
arising out of, or related to, this Agreement and the rights and obligations
created herein, or the breach, validity, existence or termination hereof, shall
be settled by Arbitration to be conducted in accordance with the Commercial
Rules of Arbitration of the American Arbitration Association, except as such
Commercial Rules may be changed by this Section 9.2. The disputes, claims or
controversies shall be decided by three independent arbitrators (that is,
arbitrators having no substantial economic or other material relationship with
the parties), one to be appointed by Spinco and one to be appointed by EVI
within fourteen days following the submission of the claim to the parties hereto
and the third to be appointed by the two so appointed within five days. Should
either party refuse or neglect to join in the timely appointment of the
arbitrators, the other party shall be entitled to select both arbitrators.
Should the two arbitrators fail timely to appoint a third arbitrator, either
party may apply to the Chief Judge of the United States

                                     - 19 -

<PAGE>   21



District Court for the Southern District of Texas to make such appointment. The
arbitrators shall have ninety days after the selection of the third arbitrator
within which to allow discovery, hear evidence and issue their decision or award
and shall in good faith attempt to comply with such time limits; provided,
however, if two of the three arbitrators believe additional time is necessary to
reach a decision, they may notify the parties and extend the time to reach a
decision in thirty day increments, but in no event to exceed an additional
ninety days. Discovery of evidence shall be conducted expeditiously by the
Parties, bearing in mind the parties desire to limit discovery and to expedite
the decision or award of the arbitrators at the most reasonable cost and expense
of the parties. Judgment upon an award rendered pursuant to such Arbitration may
be entered in any court having jurisdiction, or application may be made to such
court for a judicial acceptance of the award, and an order of enforcement, as
the case may be. The place of Arbitration shall be Houston, Texas. The decision
of the arbitrators, or a majority thereof, made in writing, shall be final and
binding upon the parties hereto as to the questions submitted, and each party
shall abide by such decision. Notwithstanding the provisions of this Section
9.2, neither party shall be prohibited from seeking injunctive relief pending
the completion of any arbitration. The costs and expenses of the arbitration
proceeding, including the fees of the arbitrators and all costs and expenses,
including legal fees and witness fees, incurred by the prevailing party, shall
be borne by the losing party.

        Solely for purposes of injunctive relief, orders in aid of arbitration
and entry of the arbitrator's award:

                  (a) each of the parties hereto irrevocably consents to the
        non-exclusive jurisdiction of, and venue in, any state court located in
        Harris County, Texas or any federal court sitting in the Southern
        District of Texas in any suit, action or proceeding seeking injunctive
        relief, arising out of or relating to this Agreement or any of the other
        agreements contemplated hereby and any other court in which a matter
        that may result in a claim for indemnification hereunder by an EVI
        Indemnified Party may be brought with respect to any claim for
        indemnification by an EVI Indemnified Party;

                  (b) each of the parties hereto waives, to the fullest extent
        permitted by law, any objection that it may now or hereafter have to the
        laying of venue of any suit, action or proceeding seeking injunctive
        relief, orders in aid of arbitration or entry of an arbitration arising
        out of or relating to this Agreement or any of the other agreements
        contemplated hereby brought in any state court located in Harris County,
        Texas or any federal court sitting in the Southern District of Texas or
        any other court in which a matter that may result in a claim for
        indemnification hereunder by an EVI Indemnified Party may be brought
        with respect to any claim for indemnification by an EVI Indemnified
        Party, and further irrevocably waive any claim that any such suit,
        action or proceeding brought in any such court has been brought in an
        inconvenient forum;

                  (c) each of the parties hereto irrevocably designates,
        appoints and empowers CT Corporation System, Inc. and any successor
        thereto as its designee, appointee and agent to receive, accept and
        acknowledge for and on its behalf, and in respect of its property,

amended, superseded, canceled, renewed or extended, and the terms hereof may be
waived, only by a written instrument signed by the parties or, in the case of a
waiver, by the party waiving compliance. No delay on the part of either party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of either party of any such right,
power or privilege, or any single or partial exercise of any such right, power
or privilege, preclude any further exercise thereof or the exercise of any other
such right, power or privilege.

        9.6 Governing Law. The parties agree that the laws of the State of Texas

                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger, dated as of the 5th day of December,
1996 (this "Agreement"), is among ENERGY VENTURES, INC., a Delaware corporation
("EVI"), GULFMARK ACQUISITION CO., a Delaware corporation and wholly-owned
subsidiary of EVI ("Sub"), GULFMARK INTERNATIONAL, INC., a Delaware corporation
("GulfMark"), and NEW GULFMARK INTERNATIONAL, INC., a Delaware corporation and
wholly-owned subsidiary of GulfMark ("Spinco").

         WHEREAS, subject to and in accordance with the terms and conditions of
this Agreement, the respective Boards of Directors of EVI, Sub and GulfMark, and
EVI as sole stockholder of Sub, have approved the merger of Sub with and into
GulfMark (the "Merger"), whereby each issued and outstanding share of common
stock, par value $1.00 per share, of GulfMark ("GulfMark Common Stock") not
owned directly or indirectly by GulfMark will be converted into the right to
receive .6695 of one share of common stock, par value $1.00 per share, of EVI
("EVI Common Stock"); and

         WHEREAS, as a condition to the Merger, GulfMark will contribute to
Spinco (a) all of the stock of GulfMark's subsidiaries other than Ercon (the
"Marine Subsidiaries") and (b) the general corporate assets of GulfMark
(excluding (i) all EVI Common Stock held by GulfMark, (ii) any and all property,
assets, claims and rights, tangible and intangible of Ercon, as defined herein,
(iii) the original tax, accounting and other corporate records of GulfMark and
(iv) all of the shares of common stock and other ownership interests held by
GulfMark in American Independent Oil Company ("AIOC"), such excluded assets
being referred to herein as the "Excluded Assets") (the "Assets") and Spinco
will assume certain liabilities associated with the Assets, the Marine
Subsidiaries and GulfMark (the "Contribution") pursuant to an Agreement and Plan
of Distribution between GulfMark, Spinco and EVI in substantially the form
attached hereto as Exhibit A (the "Distribution Agreement");

         WHEREAS, as a condition to the Merger, GulfMark will distribute to its
stockholders prior to the Merger all of the outstanding stock of Spinco (the
"Distribution");

         WHEREAS, for federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section
368(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the "Code"), and
the Contribution and Distribution qualify as transactions within the meaning of
Sections 368(a)(1)(D) and 355 of the Code; and

         WHEREAS, the parties hereto desire to set forth certain
representations, warranties and covenants made by each to the other as an
inducement to the consummation of the Merger;

         NOW, THEREFORE, in consideration of the premises and of the mutual
representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:


                                        1

<PAGE>   6



                                    ARTICLE I

                                   THE MERGER

         1.1 THE MERGER. Subject to and in accordance with the terms and
conditions of this Agreement and in accordance with the General Corporation Law
of the State of Delaware ("DGCL"), at the Effective Time (as defined in Section
1.3), Sub shall be merged with and into GulfMark. As a result of the Merger, the
separate corporate existence of Sub shall cease and GulfMark shall continue as
the surviving corporation (sometimes referred to herein as the "Surviving
Corporation"), and all the properties, rights, privileges, powers and franchises
of Sub and GulfMark shall vest in the Surviving Corporation, without any
transfer or assignment having occurred, and certain liabilities, debts and
duties of Sub and GulfMark shall attach to the Surviving Corporation, all in
accordance with the DGCL and subject to the provisions of the Distribution
Agreement.

         1.2 CLOSING DATE. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Fulbright &
Jaworski L.L.P, Houston, Texas, as soon as practicable after the satisfaction or
waiver of the conditions set forth in Article VI or at such other time and place
and on such other date as EVI and GulfMark shall agree; provided that the
closing conditions set forth in Article VI shall have been satisfied or waived
at or prior to such time. The date on which the Closing occurs is herein
referred to as the "Closing Date".

         1.3 CONSUMMATION OF THE MERGER. As soon as practicable on the Closing
Date, the parties hereto will cause the Merger to be consummated by filing with
the Secretary of State of Delaware a certificate of merger in such form as
required by, and executed in accordance with, the relevant provisions of the
DGCL. The "Effective Time" of the Merger, as that term is used in this
Agreement, shall mean such time as a certificate of merger is duly filed with
the Delaware Secretary of State or at such later time (not to exceed 90 days
from the date the Certificate is filed) as is specified in the certificate of
merger pursuant to the mutual agreement of EVI and GulfMark.

         1.4 EFFECTS OF THE MERGER. The Merger shall have the effects set forth
in the applicable provisions of the DGCL. If at any time after the Effective
Time of the Merger, the Surviving Corporation shall consider or be advised that
any further assignments or assurances in law or otherwise are necessary or
desirable to vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation, all rights, title and interests in all real estate and other
property and all privileges, powers and franchises of GulfMark and Sub, the
Surviving Corporation and its proper officers and directors, in the name and on
behalf of GulfMark and Sub, shall execute and deliver all such proper deeds,
assignments and assurances in law and do all things necessary and proper to
vest, perfect or confirm title to such property or rights in the Surviving
Corporation and otherwise to carry out the purpose of this Agreement, and the
proper officers and directors of the Surviving Corporation are fully authorized
in the name of GulfMark or otherwise to take any and all such action.

         1.5      CERTIFICATE OF INCORPORATION; BYLAWS.  The Certificate of 
Incorporation of GulfMark, as amended by the amendment set forth in Exhibit B 
attached hereto, shall be the

                                        2

<PAGE>   7



Certificate of Incorporation of the Surviving Corporation and thereafter shall
continue to be its Certificate of Incorporation until amended as provided
therein or under the DGCL. The bylaws of Sub, as in effect immediately prior to
the Effective Time, shall be the bylaws of the Surviving Corporation and
thereafter shall continue to be its bylaws until amended as provided therein or
under the DGCL.

         1.6 DIRECTORS AND OFFICERS. The directors of Sub immediately prior to
the Effective Time shall be the directors of the Surviving Corporation at and
after the Effective Time, each to hold office in accordance with the Certificate
of Incorporation and bylaws of the Surviving Corporation, and the officers of
Sub immediately prior to the Effective Time shall be the officers of the
Surviving Corporation at and after the Effective Time, in each case until the
earlier of their resignation or removal or their respective successors are duly
elected or appointed and qualified.

         1.7 CONVERSION OF SECURITIES. Subject to the terms and conditions of
this Agreement, at the Effective Time, by virtue of the Merger and without any
action on the part of EVI, GulfMark, Sub or their stockholders:

                  (a) Subject to adjustment pursuant to Section 1.7(e) hereof,
         each share of GulfMark Common Stock issued and outstanding immediately
         prior to the Effective Time (the "Shares"), shall be converted into the
         right to receive .6695 of a share of EVI Common Stock (the "Exchange
         Ratio"); provided, however, that no fractional shares of EVI Common
         Stock shall be issued and in lieu thereof, a cash payment shall be made
         in accordance with Section 1.7(d) hereof. Except as set forth in the
         preceding sentence with respect to cash in lieu of fractional shares,
         no other consideration will be paid to GulfMark or its stockholders.

                  (b) Each Share owned directly or indirectly by GulfMark as
         treasury stock and each Share owned by Sub, EVI or any direct or
         indirect wholly-owned subsidiary of EVI or of GulfMark immediately
         prior to the Effective Time shall be canceled and extinguished without
         any conversion thereof and no payment shall be made with respect
         thereto.

                  (c) Each share of common stock, par value $1.00 per share, of
         Sub issued and outstanding immediately prior to the Effective Time
         shall be converted into one fully paid and nonassessable share of
         common stock, $1.00 par value per share, of the Surviving Corporation.

                  (d) No fractional shares of EVI Common Stock shall be issued
         in the Merger. All fractional shares of EVI Common Stock that a holder
         of Shares would otherwise be entitled to receive as a result of the
         Merger shall be aggregated and if a fractional share of EVI Common
         Stock results from such aggregation (i) such fractional share of EVI
         Common Stock shall be disregarded and the shares of EVI Common Stock
         issuable to such holder shall be rounded off to the nearest whole share
         of EVI Common Stock if such fractional share of EVI Common Stock
         represents less than one-half of one percent of the total shares of EVI
         Common Stock such holder is entitled to receive in the Merger and (ii)
         in all other cases, such holder shall be entitled to receive, in lieu
         of a fractional

                                        3

<PAGE>   8



         share of EVI Common Stock, an amount in cash determined by multiplying
         the average of the daily closing sale price per share of EVI Common
         Stock on the New York Stock Exchange ("NYSE") for the ten trading days
         immediately preceding the Effective Time of the Merger by the fraction
         of a share of EVI Common Stock to which such holder would otherwise
         have been entitled. No such cash in lieu of fractional shares of EVI
         Common Stock shall be paid to any holder of fractional shares of EVI
         Common Stock until Certificates (as defined in Section 1.8(c))
         representing such shares of EVI Common Stock are surrendered and
         exchanged in accordance with Section 1.8(c). The total amount of cash
         to be received by the stockholders of GulfMark in lieu of fractional
         shares of EVI Common Stock will not exceed one percent of the total
         fair market value of the EVI Common Stock (as of the date on which the
         Effective Time occurs) to be issued in the Merger.

The Exchange Ratio is based on (i) 3,338,852 shares of GulfMark Common Stock
being issued and outstanding immediately prior to the Effective Time. In the
event the number of shares of GulfMark Common Stock outstanding immediately
prior to the Effective Time is greater or less than 3,338,852, or the number of
shares of EVI Common Stock held by GulfMark is greater or less than 2,235,572,
the Exchange Ratio shall be adjusted to equal the number of shares of EVI Common
Stock held by GulfMark immediately prior to the Effective Time divided by the
number of shares of GulfMark Common Stock issued and outstanding immediately
prior to the Effective Time.

         1.8      EXCHANGE OF CERTIFICATES.

                  (a) Exchange Agent. Prior to the Effective Time of the Merger,
         EVI shall select a bank or trust company to act as exchange agent (the
         "Exchange Agent") for the issue of shares of EVI Common Stock upon
         surrender of certificates representing Shares.

                  (b) Payment of Merger Consideration. EVI shall take all steps
         necessary to enable and cause there to be provided to the Exchange
         Agent on a timely basis, as and when needed after the Effective Time of
         the Merger, certificates for the shares of EVI Common Stock to be
         issued upon the conversion of the Shares pursuant to Section 1.7. EVI
         or the Surviving Corporation shall timely make available to the
         Exchange Agent any cash necessary to make payments in lieu of
         fractional shares.

                  (c) Exchange Procedure. As soon as reasonably practical after
         the Effective Time of the Merger, the Exchange Agent shall mail to each
         holder of record of a certificate or certificates that immediately
         prior to the Effective Time of the Merger represented outstanding
         Shares (the "Certificates"), other than EVI, Sub and GulfMark and any
         directly or indirectly wholly-owned subsidiary of EVI, Sub or GulfMark,
         (i) a letter of transmittal (which shall specify that delivery shall be
         effected, and risk of loss and title to the Certificates shall pass,
         only upon delivery of the Certificates to the Exchange Agent and shall
         be in a form and have such other provisions as EVI and Sub may
         reasonably specify) and (ii) instructions for use in effecting the
         surrender of the Certificates in exchange for the certificates
         representing the shares of EVI Common Stock and any cash in lieu of a
         fractional share. Upon surrender of a Certificate for cancellation to
         the Exchange Agent or to such other agent or agents as may be appointed

         by the Surviving Corporation, together with such letter of transmittal,
         duly executed, and such other documents as may reasonably be required
         by the Exchange Agent, the holder of such Certificate shall be entitled
         to receive in exchange therefor a certificate or certificates
         representing the number of whole shares of EVI Common Stock into which
         the Shares theretofore represented by such Certificate shall have been
         converted pursuant to Section 1.7 and any cash payable in lieu of a
         fractional Share, and the Certificate so surrendered shall forthwith be
         canceled. If the shares of EVI Common Stock are to be issued to an
         individual, corporation, limited liability company, partnership,
         governmental authority or any other entity (a "Person"), other than the
         person in whose name the Certificate so surrendered is registered, it
         shall be a condition of exchange that such Certificate shall be
         properly endorsed or otherwise in proper form for transfer and that the
         Person requesting such exchange shall pay any transfer or other taxes
         required by reason of the exchange to a Person other than the
         registered holder of such Certificate or establish to the satisfaction
         of the Surviving Corporation that such tax has been paid or is not
         applicable. Until surrendered as contemplated by this Section 1.8, each
         Certificate shall be deemed at any time after the Effective Time of the
         Merger to represent only the right to receive upon such surrender the
         number of shares of EVI Common Stock and cash, if any, in lieu of
         fractional shares of EVI Common Stock into which the Shares theretofore
         represented by such Certificate shall have been converted pursuant to
         Section 1.7. The Exchange Agent shall not be entitled to vote or
         exercise any rights of ownership with respect to the shares of EVI
         Common Stock held by it from time to time hereunder, except that it
         shall receive and hold all dividends or other distributions paid or
         distributed with respect thereto for the account of Persons entitled
         thereto.

                  (d) Distributions with Respect to Unexchanged Shares. No
         dividends or other distributions declared or made after the Effective
         Time of the Merger with respect to the shares of EVI Common Stock with
         a record date after the Effective Time of the Merger shall be paid to
         the holder of any unsurrendered Certificate with respect to the shares
         of EVI Common Stock represented thereby and no cash payment in lieu of
         fractional shares shall be paid to any such holder pursuant to Section
         1.7(d) until the holder of record of such Certificate shall surrender
         such Certificate. Subject to the effect of applicable laws, following
         surrender of any such Certificate, there shall be paid to the record
         holder of the Certificates representing the shares of EVI Common Stock
         issued in exchange therefor, without interest, (i) at the time of such
         surrender, the amount of any cash payable in lieu of a fractional share
         of EVI Common Stock to which such holder is entitled pursuant to
         Section 1.7(d) and the amount of dividends or other distributions with
         a record date after the Effective Time of the Merger theretofore paid
         with respect to such whole shares of EVI Common Stock, as the case may
         be, and (ii) at the appropriate payment date, the amount of dividends
         or other distributions with a record date after the Effective Time of
         the Merger but prior to surrender and a payment date subsequent to
         surrender payable with respect to such whole shares of EVI Common
         Stock.

                  (e) No Further Ownership Rights in Shares. All shares of EVI
         Common Stock issued upon the surrender of Certificates in accordance
         with the terms of this Article I, together with any dividends payable
         thereon to the extent contemplated by this Section 1.8, shall be deemed
         to have been exchanged and paid in full satisfaction of all

                                        5

<PAGE>   10



         rights pertaining to the Shares theretofore represented by such
         Certificates and there shall be no further registration of transfers on
         the stock transfer books of the Surviving Corporation of the Shares
         that were outstanding immediately prior to the Effective Time of the
         Merger. If, after the Effective Time of the Merger, Certificates are
         presented to the Surviving Corporation for any reason, they shall be
         canceled and exchanged as provided in this Article I.

                  (f) None of EVI, Sub, GulfMark, the Surviving Corporation or
         their transfer agents shall be liable to a holder of the Shares for any
         amount properly paid to a public official pursuant to applicable
         property, escheat or similar laws.

         1.9 TAKING OF NECESSARY ACTION; FURTHER ACTION. The parties hereto
shall take all such reasonable and lawful action as may be necessary or
appropriate in order to effectuate the Merger and the Distribution as promptly
as possible. If, at any time after the Effective Time, any such further action
is necessary or desirable to carry out the purposes of this Agreement or the
Distribution Agreement, and to vest the Surviving Corporation with full right,
title and possession to all assets, property, rights, privileges, powers and
franchises of GulfMark or Sub as of the Effective Time, such corporations shall
direct their respective officers and directors to take all such lawful and
necessary action.

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

         2.1      REPRESENTATIONS AND WARRANTIES OF EVI AND SUB.  EVI and Sub 
hereby jointly and severally represent and warrant to GulfMark that:

                  (a) Organization and Compliance with Law. Each of EVI and Sub
         is a corporation duly organized, validly existing and in good standing
         under the laws of the state of Delaware and has all requisite corporate
         power and corporate authority to own, lease and operate all of its
         properties and assets and to carry on its business as now being
         conducted, except where the failure to be so organized, existing or in
         good standing would not have a material adverse effect on the financial
         condition of EVI and its subsidiaries (the "EVI Subsidiaries"), taken
         as a whole (an "EVI MAE"). Each of EVI and Sub is duly qualified to do
         business, and is in good standing, in each jurisdiction in which the
         property owned, leased or operated by it or the nature of the business
         conducted by it makes such qualification necessary, except in such
         jurisdictions where the failure to be duly qualified would not have an
         EVI MAE. Each of EVI and Sub is in compliance with all applicable laws,
         judgments, orders, rules and regulations, except where such failure
         would not have an EVI MAE. EVI has heretofore delivered to GulfMark
         true and complete copies of EVI's Certificate of Incorporation (the
         "EVI Certificate") and Sub's Certificate of Incorporation and their
         respective bylaws as in existence on the date hereof.

                  (b)      Capitalization.

                           (i) The authorized capital stock of EVI consists of
                  40,000,000 shares of EVI Common Stock, par value $1.00 per
                  share, and 3,000,000 shares of preferred stock, par value
                  $1.00 per shares ("EVI Preferred Stock"). As of September 30,
                  1996, there were issued and outstanding 22,939,625 shares of
                  EVI Common Stock. As of October 8, 1996, 1,550,268 shares of
                  EVI Common Stock were reserved for issuance pursuant to EVI's
                  1981 Employee Stock Option Plan, 1992 Employee Stock Option
                  Plan, Non-Employee Director Stock Option Plan and restricted
                  stock plan for foreign key employees, of which 834,268 shares
                  of EVI Common Stock were reserved for issuance upon exercise
                  of outstanding options. At October 8, 1996, there were no
                  shares of EVI Preferred Stock issued or outstanding. No holder
                  of EVI Common Stock is entitled to preemptive rights under
                  Delaware law or EVI's Certificate of Incorporation.

                           (ii) As of the date hereof, the authorized capital
                  stock of Sub consists of 1,000 shares of common stock, par
                  value $1.00 per share, all of which are validly issued, fully
                  paid and nonassessable and are owned by EVI.

                           (iii) Each share of EVI Common Stock to be issued
                  hereunder as a result of the Merger will be fully paid and
                  non-assessable upon issuance.

                  (c) Authorization and Validity of Agreement. The execution and
         delivery by EVI and Sub of this Agreement and the consummation by each
         of them of the transactions contemplated hereby have been duly
         authorized by all necessary corporate action (subject only, with
         respect to the Merger, to approval of this Agreement by each of their
         stockholders as provided for in Section 5.3). On or prior to the date
         hereof, the Board of Directors of EVI or duly authorized committee
         thereof has determined to recommend approval of the Merger to the
         stockholders of EVI, and such determination is in effect on the date
         hereof. This Agreement has been duly executed and delivered by EVI and
         Sub and is the valid and binding obligation of EVI and Sub, enforceable
         against EVI and Sub in accordance with its terms.

                  (d) No Approvals or Notices Required; No Conflict . Neither
         the execution and delivery of this Agreement nor the performance by EVI
         or Sub of its obligations hereunder, nor the consummation of the
         transactions contemplated hereby by EVI and Sub, will (i) conflict with
         the EVI Certificate or the bylaws of EVI or Sub; (ii) assuming
         satisfaction of the requirements set forth in clause (iii) below,
         violate any provision of law applicable to EVI or any of the EVI
         Subsidiaries; (iii) except for (A) requirements of Federal or state
         securities laws, (B) requirements arising out of the Hart-Scott-Rodino
         Antitrust Improvements Act of 1976 (the "HSR Act"), (C) requirements of
         notice filings in such foreign jurisdictions as may be applicable, and
         (D) the filing of a Certificate of Merger by Sub in accordance with the
         DGCL, require any consent or approval of, or filing with or notice to,
         any public body or authority, domestic or foreign, under any provision
         of law applicable to EVI or any of the EVI Subsidiaries; or (iv)
         require any consent, approval or notice under, or violate, breach, be
         in conflict with or constitute a default (or an event that, with notice
         or lapse of time or both, would constitute a default)

         creation or imposition of any lien, mortgage, pledge, security
         interest, restriction on transfer, option, charge, right of any third
         Person or any other encumbrance of any nature (a "Lien") upon any
         properties, assets or business of EVI or any of the EVI Subsidiaries
         under, any note, bond, indenture, mortgage, deed of trust, lease,
         franchise, permit, authorization, license, contract, instrument or
         other agreement or commitment or any order, judgment or decree to which
         EVI or any of the EVI Subsidiaries is a party or by which EVI or any of
         the EVI Subsidiaries or any of its or their assets or properties is
         bound or encumbered, except (A) those that have already been given,
         obtained or filed and (B) those that, in the aggregate, would not have
         an EVI MAE.

                  (e) Commission Filings; Financial Statements. EVI has filed
         all reports and documents required to filed with the Securities and
         Exchange Commission (the "Commission") since December 31, 1993. All
         reports, registration statements and other filings (including all
         notes, exhibits and schedules thereto and documents incorporated by
         reference therein) filed by EVI with the Commission since December 31,
         1993, through the date of this Agreement, together with any amendments
         thereto, are sometimes collectively referred to as the "EVI Commission
         Filings". EVI has heretofore delivered to, or made accessible to,
         GulfMark copies of the EVI Commission Filings. As of the respective
         dates of their filing with the Commission, the EVI Commission Filings
         complied in all material respects with the applicable requirements of
         the Securities Act of 1934 (the "Securities Act"), the Securities
         Exchange Act of 1934 (the "Exchange Act") and the rules and regulations
         of the Commission thereunder, and did not contain any untrue statement
         of a material fact or omit to state a material fact required to be
         stated therein or necessary to make the statements made therein, in
         light of the circumstances under which they were made, not misleading.

                  (f) Absence of Certain Charges and Events. Since December 31,
         1995, except as contemplated by this Agreement or as disclosed in the
         EVI Commission Filings filed with the Commission prior to the date
         hereof, there has been no EVI MAE.

                  (g)      Tax Matters.

                           (i) Except as set forth in Section 2.1(f) of the

                  be filed on or before the Closing Date by or with respect to
                  EVI or any of the EVI Subsidiaries, or any other corporation

                  meaning of Section 1504(a) of the Code) of corporations of
                  which EVI was a member for any period ending on or prior to
                  the Closing Date, have been or will be duly and timely filed,
                  and all Taxes, including interest and penalties, due and

                  Letter, adequately provided for in reserves established by
                  EVI, except where the failure to file, pay or provide for
                  would not have a EVI MAE.

                           (ii) EVI has no present plan or intention after the
                  Merger to (A) liquidate the Surviving Corporation, (B) merge

                  the assets of Sub vested in the Surviving Corporation except
                  for dispositions made in the ordinary course of business or
                  transfers of assets to a corporation controlled by the
                  Surviving Corporation within the meaning of Section
                  368(a)(2)(C) of the Code, (E) reacquire any of the stock
                  issued to the GulfMark stockholders pursuant to the Merger,

                  the historic business of GulfMark, or (G) acquire Spinco or
                  Spinco Assets.

                           (iii) EVI is not an investment company as defined in
                  ss.368(a)(2)(F)(iii) and (iv) of the Code or as defined in the
                  Investment Company Act of 1940 and the rules and regulations
                  promulgated thereunder.

                  (h) Voting Requirements. The affirmative vote of the holders
         of a majority of the shares of EVI Common Stock present at the special
         stockholders' meeting and entitled to vote is the only vote of the

                  (i) Brokers. Except for fees and expenses payable by EVI to
         Prudential Securities Corporation, no broker, investment banker, or
         other Person acting on behalf of EVI is or will be entitled to any
         broker's, finder's or other similar fee or commission in connection
         with the transactions contemplated by this Agreement.

         time the Registration Statement is filed with the Commission, and at
         any time it is amended or supplemented or at the time it becomes
         effective under the Securities Act, contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading, and
         (ii) the Proxy Statement will, at the date the Proxy Statement is first
         mailed to EVI's stockholders and at the time of the EVI Stockholders
         Meeting, contain any untrue statement of a material fact or omit to
         state any material fact required to be stated therein or necessary in
         order to make the statements therein, in light of the circumstances
         under which they are made, not misleading. The Proxy Statement will
         comply as to form in all material respects with the requirements of the
         Exchange Act and the rules and regulations thereunder. For purposes of
         this Agreement, the parties agree that the statements made and
         information in the Registration Statement and the Proxy Statement
         relating to the Federal income tax consequences of the transactions
         contemplated hereby shall be deemed to be supplied by GulfMark and
         Spinco and not by EVI or Sub.

         2.2      REPRESENTATIONS AND WARRANTIES OF GULFMARK AND SPINCO.  Each 
of GulfMark and Spinco, jointly and severally hereby represents and warrants 
to EVI that:

                  (a) Organization. Each of GulfMark and Spinco is a corporation
         duly organized, validly existing and in good standing under the laws of
         the state of Delaware and Ercon Development Company, a wholly owned
         subsidiary of GulfMark to be merged into GulfMark prior to the
         Effective Time ("Ercon") is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Texas.
         Each of GulfMark, Spinco and Ercon has all requisite corporate power
         and corporate authority and all necessary governmental authorizations
         to own, lease and operate all of its properties and assets and to carry
         on its business as now being conducted, except where the failure to be
         so organized, existing or in good standing or to have such governmental
         authority would not (i) have a material adverse effect on the financial
         condition of GulfMark or Ercon after giving effect to the Distribution
         or (ii) prevent or adversely affect the ability of GulfMark and Spinco
         to perform and comply with their respective obligations under this
         Agreement, the Distribution Agreement or any other agreement to be
         executed and delivered in connection with the transactions contemplated
         hereby or thereby (a "GulfMark MAE"). Except as set forth in Section
         2.2(a) of the disclosure letter delivered by GulfMark to EVI on the
         date hereof (the "GulfMark Disclosure Letter"), each of GulfMark, Ercon
         and Spinco is duly qualified as a foreign corporation to do business,
         and is in good standing, in each jurisdiction in which the property
         owned, leased or operated by it or the nature of the business conducted
         by it makes such qualification necessary, except in such jurisdictions
         where the failure to be duly qualified does not and would not have a
         GulfMark MAE. Each of GulfMark, Ercon and Spinco is in compliance with
         all applicable laws, judgments, orders, rules and regulations, domestic
         and foreign, except where failure to be in such compliance would not
         have a GulfMark MAE. GulfMark has heretofore delivered to EVI true and
         complete copies of GulfMark's Certificate of Incorporation (the
         "GulfMark Certificate") and bylaws, Spinco's Certificate of
         Incorporation and bylaws and Ercon's Articles of Incorporation and
         bylaws as in existence on the date hereof.

                  (b)      Capitalization.

                           (i) The authorized capital stock of GulfMark consists
                  of 10,000,000 shares of GulfMark Common Stock, par value $1.00
                  per share and 500,000 shares of Preferred Stock, par value
                  $50.00 per share. As of September 30, 1996, there were issued

                  of 10,000 shares of Ercon Common Stock, par value $1.00 per
                  share. As of September 30, 1996, there were issued and

                  stock, or any agreement or arrangement providing for
                  registration rights with respect to any capital stock or other
                  securities of Ercon. GulfMark owns all of the issued and
                  outstanding Common Stock of Ercon.

                           (iii) As of the date hereof, there are outstanding

                  Option Plan and the Amended and Restated 1993 Non-Employee
                  Director Stock Option Plan (collectively the "GulfMark
                  Plans"). All GulfMark Options will be transferred to Spinco's
                  Adjustment Plans prior to the Effective Time. As of the
                  Effective Time, there will be no options outstanding under the
                  GulfMark Plans. There are not now (other than as set forth in

                  shares of any class of capital stock of GulfMark, or
                  contracts, understandings or arrangements to which GulfMark is
                  a party, or by which it is or may be bound, to issue
                  additional shares of its capital stock or options, warrants,
                  scrip or rights to subscribe for, or securities or rights
                  convertible into or exchangeable for, any additional shares of
                  its capital stock.

                           (iv) GulfMark owns all of the issued and outstanding
                  Common Stock of Spinco.

                  (d) No Approvals or Notices Required; No Conflict with
         Instruments to which GulfMark is a Party. The execution and delivery of
         this Agreement and the Other Agreements do not, and the consummation of
         the transactions contemplated hereby and thereby and compliance with
         the provisions hereof and thereof will not, conflict with, or result in
         any violation of, or default (with or without notice or lapse of time,
         or both) under, or give rise to a right of termination, cancellation or

         Agreement by GulfMark, and Spinco or the consummation by GulfMark,
         Ercon and Spinco of the transactions contemplated hereby, except for

         or information statement relating to Stockholder Approval (such proxy
         or information statement as amended or supplemented from time to time,
         the "Proxy Statement"), and (B) such reports under Section 13(a) of the
         Exchange Act as may be required in connection with this Agreement and
         the transactions contemplated hereby, (iii) the filing of a Certificate
         of Merger with the Delaware Secretary of State and the Texas Secretary
         of State with respect to the merger of Ercon into GulfMark and the
         filing of appropriate document(s) with the relevant authority of other
         states in which each of Ercon and GulfMark is qualified to do business,
         (iv) the filing of the Certificate of Merger with the Delaware
         Secretary of State with respect to the Merger as provided in the DGCL
         and appropriate documents with the relevant authorities of other states
         in which each of GulfMark and Spinco is qualified to do business and
         (v) such other consents, approvals, orders, authorizations,
         registrations, declarations, filings and notices as are set forth in
         Section 2.2(d) of the GulfMark Disclosure Letter.

                  (e) Commission Filings; Financial Statements. GulfMark has
         filed all reports, registration statements and other filings, together
         with any amendments required to be made with respect thereto, that they
         have been required to file with the Commission. All reports,
         registration statements and other filings (including all notes,
         exhibits and schedules thereto and documents incorporated by reference
         therein) filed by GulfMark with the Commission since December 31, 1993
         through the date of this Agreement, together with any amendments
         thereto, are sometimes collectively referred to as the "GulfMark
         Commission Filings." GulfMark has heretofore delivered to EVI copies of
         the GulfMark Commission Filings. As of the respective dates of their
         filing with the Commission, the GulfMark Commission Filings complied in
         all material respects with the Securities Act, the Exchange Act and the
         rules and regulations of the Commission thereunder, and did not contain
         any untrue statement of a material fact or omit to state a material
         fact required to be stated therein or necessary to make the statements
         made therein, in light of the circumstances under which they were made,
         not misleading. To the best knowledge of GulfMark, all material
         contracts of GulfMark and its subsidiaries have been included in the
         GulfMark's filings with the Commission since the initial registration
         of its stock under the Exchange Act, except for those contracts not
         required to be filed pursuant to the rules and regulations of the
         Commission.

                  Each of the consolidated financial statements (including any
         related notes or schedules) included in the GulfMark Commission Filings
         was prepared in accordance with generally accepted accounting
         principles applied on a consistent basis (except as may be noted
         therein or in the notes or schedules thereto) and complied with the
         rules and regulations of the Commission. Such consolidated financial
         statements fairly present the consolidated financial position of
         GulfMark as of the dates thereof and the results of operations, cash
         flows and changes in stockholders' equity for the periods then ended
         (subject, in the case of the unaudited interim financial statements, to
         normal year-end audit adjustments on a basis comparable with past
         periods). As of the date hereof, GulfMark has no liabilities, absolute
         or contingent, that may reasonably be expected to have a GulfMark MAE,
         that are not reflected in the GulfMark Commission Filings,

                                       13

         Letter.

                  (f) Conduct of Business in the Ordinary Course; Absence of
         Certain Changes and Events. Since December 31, 1995, except as
         contemplated by this Agreement, the Distribution Agreement or as
         disclosed in the GulfMark Commission Filings or set forth in Section
         2.2(f) of the GulfMark Disclosure Letter, GulfMark and its subsidiaries
         have conducted their respective businesses only in the ordinary and
         usual course in accordance with past practice, and there has not been:
         (i) a GulfMark MAE or any other material adverse change in the
         financial condition, results of operations, assets or business of
         GulfMark, taken as a whole, or (ii) to the knowledge of GulfMark, any
         other condition, event or development that reasonably may be expected
         to result in any such material adverse change or a GulfMark MAE; (iii)
         any change by GulfMark or Ercon in its accounting methods, principles
         or practices; (iv) any revaluation by GulfMark or Ercon of any of its
         assets, including, without limitation, writing down the value of
         inventory or writing off notes or accounts receivable other than in the
         ordinary course of business and consistent with past practice; (v) any
         entry by GulfMark or Ercon into any commitment or transaction that
         would be material to GulfMark or Ercon; (vi) any declaration, setting
         aside or payment of any dividends or distributions in respect of the
         GulfMark Common Stock or any redemption, purchase or other acquisition
         of any of its securities; (vii) any damage, destruction or loss
         (whether or not covered by insurance) adversely affecting the
         properties or business of GulfMark or Ercon; (viii) any increase in
         indebtedness of borrowed money other than borrowing under existing
         credit facilities as disclosed in Section 2.2(f) of the GulfMark
         Disclosure Letter; (ix) any granting of a security interest or Lien on
         any property or assets of GulfMark or Ercon, other than (A) Liens for
         taxes not due and payable and (B) inchoate mechanics', warehousemen's
         and other statutory Liens incurred in the ordinary course of business
         (collectively, "Permitted Liens"); or (x) any increase in or
         establishment of any bonus, insurance, severance, deferred
         compensation, pension, retirement, profit sharing, stock option
         (including, without limitation, the granting of stock options, stock
         appreciation rights, performance awards or restricted stock awards),
         stock purchase or other employee benefit plan or any other increase in
         the compensation payable or to become payable to any directors,
         officers or key employees of GulfMark or Ercon or which GulfMark or
         Ercon would be responsible.

                  (g) Litigation. Except as disclosed in the GulfMark Commission
         Filings or as set forth in Section 2.2(g) of the GulfMark Disclosure
         Letter, there are no claims, actions, suits, investigations, inquiries
         or proceedings, ("Demands"), pending or, to the knowledge of GulfMark,
         threatened against or affecting (i) GulfMark or Ercon or any of their
         respective properties at law or in equity, or any of their employee
         benefit plans or fiduciaries of such plans, or (ii) Spinco or any
         GulfMark or Spinco subsidiaries or any of their respective properties
         at law or in equity, or any of their respective employee benefit plans

         located (i) that exist today or (ii) that would otherwise, if adversely
         determined, have a GulfMark MAE. None of GulfMark, Ercon

                                 multi employer plan within the

                                 Sections 406 and 407 of ERISA
                                 (unless exempt under Section 408) or
                                 Section 4975 of the Code (unless
                                 exempt);

                            (B)  Each Plan and each Benefit Program
                                 or Agreement has been administered,
                                 maintained and operated in all
                                 material respects in accordance with
                                 the terms thereof and in compliance
                                 with its governing documents and
                                 applicable law (including, where
                                 applicable, ERISA and the Code and
                                 timely filing of Form 5500's for
                                 each year);

                            (C)  There is no matter pending with
                                 respect to any of the Plans before
                                 any governmental agency, and there
                                 are no actions, suits or claims
                                 pending (other than routine claims
                                 for benefits) or, to the knowledge
                                 of GulfMark or Spinco, threatened
                                 against, or with respect to, any of
                                 the Plans or Benefit Programs or
                                 Agreements or their assets;

                            (D)  No act, omission or transaction has
                                 occurred which would result in
                                 imposition on GulfMark or any
                                 GulfMark ERISA Affiliate of breach
                                 of fiduciary duty liability damages
                                 under Section 409 of ERISA, a civil
                                 penalty assessed pursuant to
                                 subsections (c), (i) or (l) of
                                 Section 502 of ERISA or a tax
                                 imposed pursuant to Chapter 43 of
                                 Subtitle D of the Code; and

                            (E)  Except as provided in Section 5.7, the 
                                 execution and delivery of this Agreement 
                                 and the consummation of the transactions 
                                 contemplated hereby will not require GulfMark
                                 or any GulfMark ERISA Affiliate to make a 
                                 larger contribution to, or pay greater 
                                 benefits under, any Plan, Benefit Program 
                                 or Agreement than it otherwise would or
                                 create or give rise to any additional vested 
                                 rights or service credits under any Plan or 
                                 Benefit Program or Agreement or cause the 
                                 companies to make accelerated payments.

                           (iii) Except as set forth in Section 2.2(h) of the
                  GulfMark Disclosure Letter, termination of employment of any
                  employee of GulfMark or Ercon immediately after consummation
                  of the transactions contemplated by this Agreement would not
                  result in payments under the Plans, Benefit Programs or
                  Agreements which, in the aggregate, would result in imposition
                  of the sanctions imposed under Sections 280G and 4999 of the
                  Code.

                           (iv) Each Plan may be unilaterally amended or
                  terminated in its entirety without liability except as to
                  benefits accrued thereunder prior to such amendment or
                  termination.

                           (v) Except as set forth in Section 2.2(h) of the
                  GulfMark Disclosure Letter, none of the employees of GulfMark
                  or Ercon are subject to union or collective bargaining
                  agreements.

                           (vi) None of GulfMark or any of the GulfMark ERISA
                  Affiliates has agreed or is obligated to provide retiree
                  medical coverage and each of such companies has fully complied
                  with all obligations under COBRA applicable to it.

                  (i)      Taxes.

                           (i) Except as set forth in Section 2.2(i) of the
                  GulfMark Disclosure Letter, all Tax Returns of or relating to
                  any Tax that are required to be filed on or before the Closing
                  Date by or with respect to GulfMark or any GulfMark
                  Subsidiary, or any other corporation that is or was a member
                  of an affiliated group (within the meaning of Section 1504(a)
                  of the Code) of corporations of which GulfMark was a member
                  for any period ending on or prior to the Closing Date, have
                  been or will be duly and timely filed, and all Taxes,
                  including interest and penalties, due and payable pursuant to
                  such Tax Returns have been or will be duly and timely paid or
                  adequately provided for in reserves established by GulfMark or
                  any such GulfMark Subsidiary, except where the failure to
                  file, pay or provide for would not have a material adverse
                  effect on the financial condition, results of operations, or
                  business of GulfMark or otherwise result in a GulfMark MAE.
                  All income Tax returns of or with respect to GulfMark or any
                  GulfMark Subsidiary have been audited by the applicable
                  Governmental Authority, or the applicable statute of
                  limitations has expired, for all periods up to and including
                  the tax year ended December 31, 1991. There is no material
                  claim against GulfMark or any GulfMark Subsidiary with respect
                  to any Taxes, and no material assessment, deficiency or
                  adjustment has been asserted or proposed with respect to any
                  Tax Return of or with respect to GulfMark or any GulfMark
                  Subsidiary that has not been adequately provided for in
                  reserves established by GulfMark or such GulfMark Subsidiary.
                  The total amounts set up as liabilities for current and
                  deferred Taxes in the consolidated financial statements
                  included in the GulfMark Commission Filings have been prepared
                  in accordance with generally accepted accounting principles
                  and are sufficient to cover the payment of all material Taxes,
                  including any penalties or interest thereon and whether or not
                  assessed or disputed, that are, or are hereafter found to be,
                  or to have been, due with respect to the operations of
                  GulfMark or any GulfMark Subsidiary through the periods
                  covered thereby. GulfMark has (and as of the Closing Date will
                  have) made estimated tax payments for taxable years for which
                  the United States consolidated federal income Tax return is
                  not yet due required with respect to Taxes. Except as set
                  forth in Section 2.2(i) of the GulfMark Disclosure Letter, no
                  waiver or extension of any statute of limitations as to any
                  federal, state, local or foreign Tax matter has been given by
                  or requested from GulfMark or any GulfMark Subsidiary. Except
                  for statutory Liens for current Taxes not yet due, no Liens
                  for Taxes exist upon the assets of GulfMark. Except as set
                  forth in paragraph 2.2(i) of the GulfMark Disclosure Letter,
                  none of GulfMark or any GulfMark Subsidiary has filed
                  consolidated income Tax Returns with any corporation, other

                                       17

                  than consolidated federal, state or foreign income Tax returns
                  by GulfMark for any taxable period which is not now closed by
                  the applicable statute of limitations. None of GulfMark or any
                  GulfMark Subsidiary has any deferred intercompany gain as
                  defined in Treasury Regulations Section 1.1502-13.

                           (ii) As of the Closing Date, to GulfMark's knowledge,
                  there is no plan or intention by the stockholders of GulfMark
                  to sell, exchange or otherwise dispose of a number of shares
                  of EVI received in the Merger that would reduce the GulfMark
                  stockholders' ownership of EVI shares to a number of shares
                  having a value, as of the date of the Merger, of less than 50%
                  of the value of all of the formerly outstanding Shares as of
                  the same date. For purposes of this representation, Shares
                  exchanged for cash or other property or exchanged in lieu of
                  fractional shares of EVI will be treated as outstanding Shares
                  on the date of the Merger. Moreover, the shares of EVI held by
                  the GulfMark stockholders and otherwise sold, redeemed or
                  disposed of prior or subsequent to the Merger will be
                  considered in making this representation.

                           (iii) GulfMark is not an investment company as 
                  defined in ss.368(a)(2)(F)(iii) and (iv) of the Code.

                           (iv) GulfMark is not under the jurisdiction of a
                  court in a Title 11 or similar case with the meaning of
                  ss.368(a)(3)(A) of the Code.

                           (v) There is no intercorporate indebtedness existing
                  between GulfMark and EVI that was issued, acquired or will be
                  settled at a discount.

                  (j) Environmental Matters. Except as set forth in Section
         2.2(j) of the GulfMark Disclosure Letter, (i) the properties,
         operations and activities of GulfMark and each of its subsidiaries
         complies in all material respects with all applicable Environmental
         Laws; (ii) none of GulfMark or any of its GulfMark Subsidiaries is
         subject to any existing, pending or, to the knowledge of GulfMark,
         threatened action, suit, investigation, inquiry or proceeding by or
         before any governmental authority under any Environmental Law; (iii)
         except where the failure would have a GulfMark MAE, all notices,
         permits, licenses, or similar authorizations, if any, required to be
         obtained or filed by GulfMark or Ercon under any Environmental Law in
         connection with any aspect of the business of GulfMark, Ercon or any
         GulfMark Subsidiary, including without limitation those relating to the
         treatment, storage, disposal or release of a hazardous substance or
         solid waste, have been duly obtained or filed and will remain valid and
         in effect after the Merger and the Distribution, and GulfMark and Ercon
         is in compliance with the terms and conditions of all such notices,
         permits, licenses and similar authorizations; (iv) GulfMark and each of
         its subsidiaries has satisfied and are currently in compliance with all
         financial responsibility requirements applicable to their operations
         and imposed by any governmental authority under any other Environmental
         Law, and none of such parties has received any notice of noncompliance
         with any such requirements; (v) to GulfMark's knowledge, there are no
         physical or environmental conditions existing on any property currently
         owned or previously owned by GulfMark or any entity in which it has or
         had ownership interest that could reasonably be expected

                                       18

<PAGE>   23



         to give rise to any on-site or off-site remedial obligations under any
         Environmental Laws; and (vi) to GulfMark's knowledge, since the
         effective date of the relevant requirements of applicable Environmental
         Laws, all hazardous substances or solid wastes generated by GulfMark or
         used in connection with their properties or operations have been
         transported only by carriers authorized under Environmental Laws to
         transport such substances and wastes, and disposed of only at
         treatment, storage, and disposal facilities authorized under
         environmental laws to treat, store or dispose of such substances and
         wastes, and, to the knowledge of GulfMark, such carriers and facilities
         have been and are operating in compliance with such authorizations and
         are not the subject of any existing, pending, or overtly threatened
         action, investigation, or inquiry by any governmental authority in
         connection with any Environmental Laws.

                  For purposes of this Agreement, the term "Environmental Laws"
         shall mean any and all laws, statutes, ordinances, rules, regulations,
         orders or determinations of any Governmental Authority pertaining to
         health or the environment currently in effect in any and all
         jurisdictions in which the party in question and its subsidiaries own
         property or conduct business, including without limitation, the Clean
         Air Act, as amended, the Comprehensive Environmental, Response,
         Compensation, and Liability Act of 1980 ("CERCLA"), as amended, the
         Federal Water Pollution Control Act, as amended, the Occupational
         Safety and Health Act of 1970, as amended, the Resource Conservation
         and Recovery Act of 1976 ("RCRA"), as amended, the Safe Drinking Water
         Act, as amended, the Toxic Substances Control Act, as amended, the
         Hazardous & Solid Waste Amendments Act of 1984, as amended, the

         Act of 1990 ("OPA"), any state laws pertaining to the handling of oil
         and gas exploration and production wastes or the use, maintenance, and
         closure of pits and impoundments, and all other environmental
         conservation or protection laws. For purposes of this Agreement, the
         terms "hazardous substance" and "release" have the meanings specified
         in RCRA; provided, however, that to the extent the laws of the state in
         which the property is located establish a meaning for "hazardous
         substance," "release," "solid waste" or "disposal" that is broader than
         that specified in either CERCLA or RCRA, such broader meaning shall
         apply. For purposes of this Agreement, the term "Governmental
         Authority" includes the United States, any foreign jurisdiction, the
         state, county, city, and political subdivisions in which the party in
         question owns property or conducts business, and any agency,
         department, commission, board, bureau or instrumentality of any of
         them.

                  (k) Investment Company.  GulfMark is not an investment 
         company as defined in the Investment Company Act of 1940 and the 
         rules and regulations promulgated thereunder.

                  (l) Severance Payments. Except as set forth in Section 2.2(l)
         of the GulfMark Disclosure Letter, GulfMark will not have any liability
         or obligation to pay a severance payment or similar obligation to any
         of their respective employees, officers, or directors as a result of
         the Merger or the transactions contemplated by this Agreement, nor will
         any of such Persons be entitled to an increase in severance payments or
         other benefits

                                       19

<PAGE>   24



         as a result of the Merger, the Contribution, the Distribution or the
         transactions contemplated by this Agreement or the Other Agreements in
         the event of the subsequent termination of their employment.

                  (m) Voting Requirements. The affirmative vote of the holders
         of a majority of the outstanding shares of GulfMark Common Stock is the
         only vote of the holders of any class or series of the capital stock of
         GulfMark necessary to approve this Agreement, the Merger, the

         broker's, finder's or other similar fee or commission in connection
         with the transactions contemplated by this Agreement.

                  unbilled) relating to the business conducted by Ercon, (6)
                  cash in the amount of $300,000 and (7) cash in the amount of
                  the transactional expenses of GulfMark to be paid by GulfMark
                  relating to the Contribution, the Distribution and the Merger;

                           (ii) the liabilities of GulfMark shall consist only
                  of certain expenses related to the Merger and the Distribution
                  which shall have been fully reserved for in the Net Working
                  Capital, and GulfMark's accounts payable relating to the
                  business conducted by Ercon, which shall have been fully
                  reserved for in the Net Working Capital;

                           (iii) all obligations and liabilities (fixed or
                  contingent, known or unknown) of GulfMark shall have been
                  assumed by Spinco other than liabilities described in clause
                  (ii) and the obligation to perform in the future under
                  contracts relating to Ercon that will be identified on
                  schedules to the Distribution Agreement; and

                           (iv) the Net Working Capital of GulfMark shall equal
                  $300,000.  "Net Working Capital" shall mean the current 
                  assets of GulfMark excluding inventory, less the liabilities
                  of GulfMark as reflected on the balance sheet of GulfMark as

                                       20

<PAGE>   25



                  of the Effective Time on an unconsolidated basis. Current
                  assets and liabilities shall have the meaning attributable to
                  them by generally accepted account principles as applied
                  historically by GulfMark, provided, however, for purposes of
                  the definition of Net Working Capital, (i) accounts receivable
                  shall be net of reserves for bad debt and doubtful accounts,
                  (ii) the stock of AIOC shall not be considered a current asset
                  and (iii) liabilities shall mean the full undiscounted amount
                  of any liabilities of GulfMark and Ercon, including any
                  liabilities that will accrue as a result of the Merger, the
                  Contribution or the Distribution, whether or not such
                  liabilities would be required to be reflected as a liability
                  by generally accepted accounting principles.

                  (p) Compliance with Laws. GulfMark, Spinco, Ercon and each of
         their respective subsidiaries hold all required, necessary or
         applicable permits, licenses, variances, exemptions, orders, franchises
         and approvals of all Governmental Entities, except where the failure to
         so hold could not reasonably be expected to have a GulfMark MAE (the
         "GulfMark Permits"). All applications with respect to such permits,
         licenses, variances, exemptions, orders, franchises and approvals were
         complete and correct in all material respects when made and neither
         GulfMark nor Spinco know of any reason why any of such permits,
         licenses, variances, exemptions, orders, franchises and approvals would
         be subject to cancellation. GulfMark, Spinco, Ercon, and each of their
         respective subsidiaries are in compliance with the terms of the
         GulfMark Permits except where the failure to so comply could not
         reasonably be expected to have a GulfMark MAE. None of GulfMark,
         Spinco, Ercon, nor any of their respective subsidiaries has violated or
         failed to comply with any statute, law, ordinance, regulation, rule,
         permit or order of any Federal, state or local government, domestic or
         foreign, or any Governmental Entity, any arbitration award or any
         judgment, decree or order of any court or other Governmental Entity,
         applicable to GulfMark, Spinco, Ercon or any of their respective
         subsidiaries or their respective business, assets or operations, except
         for violations and failures to comply that would not have a GulfMark
         MAE.

                  (q) Contracts.

                           (i) Section 2.2(q) to the GulfMark Disclosure Letter

                  agreements, contracts, indentures or other instruments
                  relating to the borrowing of money, or the guarantee of any

                  Ercon, Spinco or any of their subsidiaries is a party or any
                  of their respective properties is bound; (v) contracts or
                  agreements or amendments thereto that would be required to be
                  filed as an exhibit to an Annual Report on Form 10-K filed by
                  GulfMark as of the date hereof that has not been filed as an
                  exhibit to the GulfMark's Annual Report on Form 10-K for the
                  year ended December 31, 1995, filed by it with the

<PAGE>   26



                  Commission or any report filed with the Commission under the
                  Exchange Act since such date; (vi) all outstanding proposals
                  to which Ercon is subject to as of November 21, 1996; (vii)
                  all corporations, partnerships, limited liability companies
                  and other entities which GulfMark has owed, directly or
                  indirectly, an equity interest since 1969, in which the
                  officers of GulfMark are aware after reasonable investigation,
                  (viii) all material indemnification and guaranty or other
                  similar obligations to which GulfMark or Ercon is bound and
                  which the officers of GulfMark or Ercon, after reasonable
                  investigation, are aware, (ix) any outstanding bonds, letters
                  of credit posted or guaranteed by GulfMark or Ercon with
                  respect to any Person, (x) any covenants not to compete or
                  other obligations affecting GulfMark or Ercon that would
                  restrict the Surviving Corporation or EVI and its affiliates
                  from engaging in any business or activity which the officers
                  of GulfMark or Ercon are aware, after reasonable investigation
                  and (xi) contracts, agreements, arrangements or commitments,
                  other than the foregoing that could reasonably be considered
                  to be material to GulfMark or Ercon.

                           (ii) True and correct copies of all the instruments
                  described in Section 2.2(q) of the GulfMark Disclosure Letter
                  have been furnished or made a available to EVI. Except as
                  noted in the GulfMark Disclosure Letter, all such agreements,
                  arrangements or commitments are valid and subsisting and each
                  of GulfMark, Ercon, Spinco and their respective subsidiaries
                  to the extent each is a party, has duly performed its
                  obligations thereunder in all material respects to the extent
                  such obligations have accrued, and no breach or default
                  thereunder by GulfMark, Ercon, Spinco or their respective
                  subsidiaries or, to the knowledge of GulfMark, any other party
                  thereto has occurred that could impair the ability of each of
                  GulfMark, Ercon, Spinco or their respective subsidiaries to
                  enforce any material rights thereunder. There are no material
                  liabilities of any of the parties to any of the contracts
                  between GulfMark, Ercon, Spinco or any of their subsidiaries
                  and third parties arising from any breach of or default in any
                  provision thereof or which would permit the acceleration of
                  any obligation of any party thereto or the creation of a Lien
                  upon any asset of GulfMark, Ercon, Spinco or any of their
                  subsidiaries. Neither GulfMark nor Ercon has any information
                  that might reasonably indicate that any of the material
                  customers or suppliers to Ercon intend to cease purchasing
                  from, selling to or dealing with it, nor has any information
                  been brought to the attention of GulfMark or Ercon that might
                  reasonably lead either to believe any such customer or
                  supplier intends to alter in any material respect the amount
                  of such purchases, sales or the extent of dealings with
                  GulfMark or Ercon or would alter in any significant respect
                  such purchases, sales or dealings in the event of the
                  consummation of the transactions contemplated hereby.

                  (r)      Title to Property.

                           (i) At the Effective Time, GulfMark will have good
                  and marketable title to, or valid leasehold interests in, all
                  its properties and assets. GulfMark has good and valid title
                  to 2,235,572 shares of EVI Common Stock, free and clear

                                       22

<PAGE>   27



                  of all Liens.  GulfMark has good and valid title to 200 
                  shares of AIOC Common Stock, free and clear of all Liens.

                           (ii) Each of GulfMark and Ercon has complied in all
                  material respects with the terms of all leases to which it is
                  a party and under which it is in occupancy, and all such
                  leases are in full force and effect. Each of GulfMark and
                  Ercon enjoys peaceful and undisturbed possession under all
                  such leases.

                  (s) Insurance Policies. Section 2.2(s) of the GulfMark
         Disclosure Letter contains a correct and complete description of all
         insurance policies of GulfMark covering GulfMark, Ercon and their
         subsidiaries, any employees or other agents of GulfMark and its
         subsidiaries or any assets of GulfMark, Ercon and their subsidiaries.
         Each such policy is in full force and effect, is with responsible
         insurance carriers and is substantially equivalent in coverage and
         amount to policies covering companies of the size of GulfMark and in
         the business in which GulfMark and its subsidiaries is engaged, in
         light of the risk to which such companies and their employees,
         businesses, properties and other assets may be exposed. All retroactive
         premium adjustments under any worker's compensation policy of GulfMark
         or any of its subsidiaries have been recorded in GulfMark's financial
         statements in accordance with generally accepted accounting principles
         and are reflected in the financial statements contained in the
         Commission Filings.

                  (t) Loans. Section 2.2(t) of the GulfMark Disclosure Letter
         sets forth all existing loans, advances or other extensions of credit
         (excluding accounts receivable arising in the ordinary course of
         business) by GulfMark or Ercon subsidiaries to any party other than
         intercompany loans, advances, guaranties or extensions of credit. All
         items listed in Section 2.2(t) of the GulfMark Disclosure Letter will
         be repaid in full, or assumed by Spinco, prior to the Effective Time of
         the Merger. All intercompany obligations and loans between GulfMark and
         its subsidiaries, including Spinco, will be extinguished prior to the
         Distribution without any ongoing liability to GulfMark or Spinco with
         respect thereto, except as set forth herein or in the Distribution
         Agreement.

                  (u) No Fraudulent Transfer. GulfMark has not within the last
         twelve months made any transfer or incurred any obligation with actual
         intent to hinder, delay or defraud any entity to which it was or may
         become indebted and it has not transferred any material property
         without receiving reasonably equivalent value for any such transfer
         obligation. Both immediately prior to and immediately after the
         Distribution and the Merger, (i) the fair value of GulfMark's assets
         and Spinco's assets after the Distribution at a fair valuation exceeds
         its debts and liabilities, subordinated, contingent or otherwise, (ii)
         the present fair saleable value of GulfMark's and Spinco's property is
         greater than the amount that will be required to pay its probable
         liability on its debts and other liabilities, subordinated, contingent
         or otherwise, as such debts and liabilities become absolute and mature,
         (iii) GulfMark prior to the Distribution and Spinco after the
         Distribution each reasonably expect to be able to pay its debts and
         liabilities, subordinated, contingent or otherwise, as such debts and
         liabilities become absolute and matured, and (iv) GulfMark before the
         Distribution and Spinco after the Distribution will not have
         unreasonably small capital with which to conduct the business in which
         it is

                                       23

<PAGE>   28



         engaged as such business is now conducted and is proposed to be
         conducted. For all purposes of clauses of (i) through (iv), the amount
         of contingent liabilities at any time shall be computed as the amount
         that, in light of all the facts and circumstances existing at such
         time, represents the amount that can reasonably be expected to become
         an actual or matured liability.

                  (v) Information Supplied. None of the information supplied or
         to be supplied by GulfMark for inclusion or incorporation by reference
         in (i) the Registration Statement (as defined in Section 5.1) will, at
         the time the Registration Statement is filed with the Commission, and
         at any time it is amended or supplemented or at the time it becomes
         effective under the Securities Act, contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading, and
         (ii) the Proxy Statement will, at the date the Proxy Statement is first
         mailed to GulfMark's stockholders and at the time of the GulfMark
         Stockholders Meeting, contain any untrue statement of a material fact
         or omit to state any material fact required to be stated therein or
         necessary in order to make the statements therein, in light of the
         circumstances under which they are made, not misleading. The Proxy
         Statement will comply as to form in all material respects with the
         requirements of the Exchange Act and the rules and regulations
         thereunder. For purposes of this Agreement, the parties agree that the
         statements made and information in the Registration Statement and the
         Proxy Statement relating to the Federal income tax consequences of the
         transactions contemplated hereby shall be deemed to be supplied by
         GulfMark and Spinco and not by EVI or Sub.

         meetings to approve or reject pending proposals and contracts. If no
         EVI representative attends the weekly meeting to make such decisions,
         Ercon shall forward the weekly proposals listing to the EVI
         representative; unless EVI objects in writing, proposals and contracts
         shall be deemed approved by EVI two (2) business days after receipt of
         the weekly proposals listing;

                  (e) GulfMark shall not become bound by any agreement or

         to, perform their respective obligations under any contracts and
         agreements to which it is a party or to which any of its assets is

         may dispute;

         $500,000, or if greater, the amount of the reserve therefor reflected

         3.2 NET WORKING CAPITAL REQUIREMENTS. GulfMark covenants that as of the
Effective Time it shall have Net Working Capital equal to $300,000. Net Working
Capital shall have the meaning set forth in Section 2.2(o) of this Agreement.

Capital 90 days after the Effective Date as follows ("Adjustment Date");

                  (a) to the extent there exists on the Adjustment Date any
         uncollected accounts receivable (including uncollected unbilled
         accounts receivable) or notes receivable which were counted in the

         Uncollected Receivables for the face amounts thereof and GulfMark shall
         assign such Uncollected Receivables to Spinco without recourse;

                  (b) on the Adjustment Date after any purchase of Uncollected
         Receivables, if it is determined that as of the Effective Time Net
         Working Capital exceeded $300,000, GulfMark shall remit any amounts in
         excess of $300,000 to Spinco in cash;

                  (c) on the Adjustment Date, after any purchase of Uncollected
         Receivables, it is determined that Net Working Capital was less than
         $300,000 at the Effective Time, Spinco shall remit to GulfMark an
         amount equal to the difference between $300,000 and the amount of Net
         Working Capital as the Effective Time (after consideration of purchases
         of Uncollected Receivables);

                  (d) the provisions of this Section 3.2 shall not affect
         Spinco's obligations under the Distribution Agreement to assume and
         indemnify EVI as set forth therein.

         3.3 AFFILIATES' AGREEMENTS. Prior to the Closing Date, GulfMark shall

GulfMark shall use its reasonable efforts to cause each such Person to deliver
to EVI on or prior to the Closing Date a written agreement confirming such
Person's obligations under Rule 145.

set forth in Article VI not being satisfied.

or warranty contained in this Agreement to be untrue or inaccurate at any time

                  (b) Subject to the receipt of a favorable Internal Revenue
         Service determination letter under Section 401(a) and 501(a) of the

         outstanding issues regarding the GulfMark 401(k) Plan in a manner
         satisfactory to EVI's counsel, EVI will cause the GulfMark 401(k) Plan
         to be merged into an EVI plan qualified under Section 401(a) and 501(a)
         of the Code ("EVI Plan"). Spinco shall be responsible for and perform
         any and all obligations relating to the (i) filing of the GulfMark
         401(k) Plan for a determination letter under Section 401(a) and 501(a)

         satisfied by Spinco as stated herein, relating to the continuation,
         qualification and merger of the GulfMark 401(k) Plan shall be paid by
         Spinco. Once the GulfMark 401(k) Plan is merged into an EVI Plan,
         Spinco shall not be responsible for liabilities relating to the
         GulfMark 401(k) Plan occurring after the merging of such plans.

                  (c) GulfMark shall transfer to Spinco all employees of

         registration statement on Form S-8 (or other appropriate form) with
         respect to the shares of Spinco Common Stock subject to the adjusted
         GulfMark options, and shall use its best efforts to maintain the
         effectiveness of such registration statement (and maintain the current
         status of any prospectus contained therein) for so long as any of the
         adjusted GulfMark options remain outstanding.

                                  MISCELLANEOUS

         7.1 TERMINATION. This Agreement may be terminated and the Merger and
the other transactions contemplated herein may be abandoned at any time prior to
the Effective Time, whether prior to or after approval by the stockholders of
EVI or the stockholders of GulfMark:

                  (a) by mutual written consent of EVI and GulfMark;

                  (b) by either EVI or GulfMark if (i) the Merger has not been
         consummated on or before March 31, 1997 (provided that the right to
         terminate this Agreement under this clause (i) shall not be available
         to any party whose breach of any representation or warranty or failure
         to fulfill any covenant or agreement under this Agreement has been the
         cause of or resulted in the failure of the Merger to occur on or before
         such date); (ii) any court of competent jurisdiction, or some other
         governmental body or regulatory authority shall have issued an order,
         decree or ruling or taken any other action restraining, enjoining or
         otherwise prohibiting the Merger; (iii) the stockholders of GulfMark
         shall not approve the Contribution, the Distribution or the Merger at
         the GulfMark stockholder meeting or at any adjournment thereof; (iv)
         the stockholders of EVI shall not approve the Merger at the EVI
         stockholder meeting or any adjournment thereof; or (v) in the exercise
         of its good faith judgment as to its fiduciary duties to its
         stockholders imposed by law, as advised by outside counsel, the Board
         of Directors of

<PAGE>   39



         GulfMark or EVI determines that such termination is appropriate in
         complying with its fiduciary obligations.

                  (c) by GulfMark if (i) EVI shall have failed to comply in any
         material respect with any of the covenants or agreements contained in
         this Agreement to be complied with or performed by EVI or Sub at or
         prior to such date of termination (provided such breach has not been
         cured within 30 days following receipt by EVI of written notice from
         GulfMark of such breach and is existing at the time of termination of
         this Agreement); (ii) any representation or warranty of EVI contained
         in this Agreement shall not be true in all respects when made (provided
         such breach has not been cured within 30 days following receipt by EVI
         of written notice from GulfMark of such breach and is existing at the
         time of termination of this Agreement) or on and as of the Effective
         Time as if made on and as of the Effective Time (except to the extent
         it relates to a particular date), except for such failures to be so
         true and correct which would not individually or in the aggregate,
         reasonably be expected to have an EVI MAE, assuming the effectiveness
         of the Merger; or (iii) the Board of Directors of EVI withdraws,
         modifies or changes its recommendation of this Agreement or the Merger
         in a manner adverse to GulfMark or shall have resolved to do any of the
         foregoing.

                  (d) by EVI if (i) GulfMark shall have failed to comply in any
         material respect with any of the covenants or agreements contained in
         this Agreement to be complied with or performed by it at or prior to
         such date of termination (provided such breach has not been cured
         within 30 days following receipt by GulfMark of written notice from EVI
         of such breach and is existing at the time of termination of this
         Agreement; (ii) any representation or warranty of GulfMark contained in
         this Agreement shall not be true in all respects when made (provided
         such breach has not been cured within 30 days following receipt by
         GulfMark of written notice from EVI of such breach and is existing at
         the time of termination of this Agreement) or on and as of the
         Effective Time as if made on and as of the Effective Time (except to
         the extent it relates to a particular date), except for such failures
         to be so true and correct which would not individually or in the
         aggregate, reasonably be expected to have a GulfMark MAE assuming the
         effectiveness of the Merger or (iii) the Board of Directors of GulfMark
         withdraws, modifies or changes its recommendation of this Agreement or
         the Merger in a manner adverse to EVI or shall have resolved to do any
         of the foregoing.

         7.2 EFFECT OF TERMINATION. In the event of termination of this
Agreement by either EVI or GulfMark as provided in Section 7.1, this Agreement
shall forthwith become void and there shall be no liability or obligation on the
part of EVI, Sub or GulfMark, except (i) with respect to this Section 7.2,
Section 5.7 and Section 7.13, and (ii) such termination shall not relieve any
party hereto for any intentional breach prior to such termination by a party
hereto of any of its representations or warranties or of any of its covenants or
agreements set forth in this Agreement.

         7.3 WAIVER AND AMENDMENT. Any provision of this Agreement may be waived
at any time by the party that is, or whose stockholders are, entitled to the
benefits thereof. This Agreement may not be amended or supplemented at any time,
except by an instrument in writing signed on behalf of each party hereto,
provided that after this Agreement has been approved and

                                       35

<PAGE>   40



adopted by the stockholders of EVI and GulfMark, this Agreement may be amended
only as may be permitted by applicable provisions of the DGCL. The waiver by any
party hereto of any condition or of a breach of another provision of this
Agreement shall not operate or be construed as a waiver of any other condition
or subsequent breach. The waiver by any party hereto of any of the conditions
precedent to its obligations under this Agreement shall not preclude it from
seeking redress for breach of this Agreement other than with respect to the
condition so waived.

         7.4 NONSURVIVAL OF REPRESENTATIONS AND WARRANTIES. Except for the
representations and warranties of Spinco contained herein, which shall survive
without limitation, none of the representations and warranties in this Agreement
shall survive the Effective Time.

         7.5 PUBLIC STATEMENTS. GulfMark and EVI agree to consult with each
other prior to issuing any press release or otherwise making any public
statement with respect to the transactions contemplated hereby, and shall not
issue any such press release or make any such public statement prior to such
consultation, except as may be required by law or applicable stock exchange
policy.

         7.6 ASSIGNMENT. This Agreement shall inure to the benefit of and will
be binding upon the parties hereto and their respective legal representatives,
successors and permitted assigns. Except as set forth in this Agreement, this
Agreement shall not be assignable by the parties hereto.

         7.8 GOVERNING LAW. All questions arising out of this Agreement and the
rights and obligations created herein, or its validity, existence,
interpretation, performance or breach shall be governed by the laws of the State
of Delaware, without regard to conflict of laws principles.

         7.9 ARBITRATION. Any disputes, claims or controversies connected with,
arising out of, or related to, this Agreement and the rights and obligations
created herein, or the breach, validity, existence or termination hereof, shall
be settled by Arbitration to be conducted in accordance with the Commercial
Rules of Arbitration of the American Arbitration Association, except as such
Commercial Rules may be changed by this Section 7.9. The disputes, claims or
controversies shall be decided by three independent arbitrators (that is,
arbitrators having no substantial economic or other material relationship with
the parties), one to be appointed by Spinco and one to be appointed by EVI
within fourteen days following the submission of the claim to the parties hereto
and the third to be appointed by the two so appointed within five days. Should
either party refuse or neglect to join in the timely appointment of the
arbitrators, the other party shall be entitled to select both arbitrators.
Should the two arbitrators fail timely to appoint a third arbitrator, either
party may apply to the Chief Judge of the United States District Court for the
Southern District of Texas to make such appointment. The arbitrators shall have
ninety days after the selection of the third arbitrator within which to allow
discovery, hear evidence and issue their decision or award and shall in good
faith attempt to comply with such time limits; provided, however, if two of the
three arbitrators believe additional time is necessary to reach a decision, they
may notify the parties and extend the time to reach a decision in thirty day
increments, but in no event to exceed an additional ninety days. Discovery of
evidence shall be conducted expeditiously by the Parties, bearing in mind the
Parties desire to limit discovery and to expedite the decision or award of the
arbitrators at the most reasonable cost and expense of the parties. Judgment
upon an award rendered pursuant to such Arbitration may be entered in any court
having jurisdiction, or application may be made to such court for a judicial
acceptance of the award, and an order of enforcement, as the case may be. The
place of Arbitration shall be Houston, Texas. The decision of the arbitrators,
or a majority thereof, made in writing, shall be final and binding upon the
parties hereto as to the questions submitted, and each party shall abide by such
decision. Notwithstanding the provisions of this Section 7.9, neither party
shall be prohibited from seeking injunctive relief pending the completion of any
arbitration. The costs and expenses of the arbitration proceeding, including the
fees of the arbitrators and all costs and expenses, including legal fees and
witness fees, incurred by the prevailing party, shall be borne by the losing
party.

         indemnification by an EVI Indemnified Party;

                  (b) each of the parties hereto waives, to the fullest extent
         permitted by law, any objection that it may now or hereafter have to

         injunctive relief, orders in aid of arbitration or entry of an arbitral
         award arising out of or relating to this Agreement or any of the other
         agreements contemplated hereby brought in any state court located in
         Harris County, Texas or any federal court sitting in the Southern
         District of Texas or any other court in which a matter that may result
         in a claim for indemnification hereunder by an EVI Indemnified Party
         may be brought with respect to any claim for indemnification by an EVI
         Indemnified Party, and further irrevocably waive any claim that any
         such suit, action or proceeding brought in any such court has been
         brought in an inconvenient forum;

                  (c) each of the parties hereto irrevocably designates,
         appoints and empowers CT Corporation System, Inc. and any successor
         thereto as its designee, appointee and agent to receive, accept and
         acknowledge for and on its behalf, and in respect of its property,

         arbitration and entry of an arbitral award..

this Agreement is held by a court of competent jurisdiction to be invalid, void
or unenforceable, the remainder of the terms, provision, covenants and
restrictions of this Agreement shall continue in full force and effect and shall
in no way be affected, impaired or invalidated.

         7.11 COUNTERPARTS.  This Agreement may be executed in counterparts, 
each of which shall be an original, but all of which together shall constitute 
one and the same agreement.

         7.12 HEADINGS.  The Section headings herein are for convenience only 
and shall not affect the construction hereof.
