ITEM 5.  OTHER EVENTS.

         MALLARD DISPOSITION

         On September 14, 1996, Energy Ventures, Inc., a Delaware corporation
(the "Company"), entered into a Stock Purchase Agreement (the "Stock Purchase
Agreement") with Parker Drilling Company, a Delaware corporation ("Parker"),
providing for the sale of the Company's Mallard Bay rig contracting division
("Mallard") to Parker in exchange for a total consideration of $338 million,
consisting of $313 million in cash and $25 million in shares of Parker's Series
D Convertible Preferred Stock.  The purchase price is subject to adjustment for
certain changes in working capital and other assets.  The Company is also
obligated under the Stock Purchase Agreement to transfer certain assets to
Mallard and to release, assume or satisfy certain liabilities with respect to
Mallard.

         The closing of the sale of Mallard is subject to certain conditions,
including the completion of necessary financing by Parker, which is currently
expected to occur prior to December 31, 1996, the receipt of all required
regulatory approvals and the expiration or termination of all waiting periods
(and extensions thereof) under the Hart-Scott-Rodino Act.  Although there can
be no assurance that the Mallard sale will be closed, the Company currently
anticipates that the sale will be consummated shortly after the completion of
Parker's financing and the receipt of the required regulatory approvals.

         A copy of the press release announcing the signing of the Stock
Purchase Agreement is filed as Exhibit 99.1 and is hereby incorporated herein
by reference.

         GEREMIA ACQUISITION

         On October 1, 1996, the Company completed the acquisition of all of
the outstanding stock of Irmos Geremia LTDA ("Geremia"), a Brazilian
manufacturer of progressive cavity pumps, for approximately $24 million plus
assumed liabilities.  The operations of Geremia will be integrated with the
Company's EVI Oil Tools division. 

         PRO FORMA FINANCIAL STATEMENTS

         The following pro forma financial statements give effect to the Mallard
disposition as if it had occurred on January 1, 1995. The Geremia acquisition
and other immaterial acquisitions completed in 1995 and 1996 are not included
in the pro forma Financial Statements.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

         The following tables set forth the unaudited pro forma condensed
consolidated balance sheet as of June 30, 1996, and statements of income for
the Company for the year ended December 31, 1995, and the six months ended June
30, 1996, after giving effect to: (i) the Company's acquisition on June 30,
1995, of Prideco, Inc. ("Prideco"), for consideration of approximately 2.25
million shares of Common Stock, (ii) the acquisition of  Tubular Corporation of
America ("TCA") for 500,000 shares of Common Stock, $14.35 million cash and a
note for $650,000, (iii) the proposed disposition of the Company's Mallard
division to Parker for $338 million, consisting of $313 million cash and $25
million in preferred stock of Parker, and (iv) the 1996 equity offering of 3.45
million shares of the Company's Common Stock.  The unaudited pro forma
condensed consolidated statements of income assume that the Prideco and TCA
acquisitions, the Mallard disposition and the 1996 equity offering occurred as
of January 1, 1995, and the unaudited pro forma condensed consolidated balance
sheet assumes that the TCA acquisition, the Mallard disposition and the 1996
equity offering occurred as of June 30, 1996.  The Prideco and TCA acquisitions
were accounted for using the purchase method of accounting.  The unaudited pro
forma condensed consolidated financial statements are based upon estimates and
assumptions related to the accounting for the TCA acquisition and the Mallard
disposition.

         The accounting for the TCA acquisition is subject to subsequent
determination and more detailed analyses, appraisals and evaluations of the
specific assets and liabilities.  The final allocation of the purchase price of
the acquisition may differ from the amounts contained in these unaudited pro
forma condensed consolidated financial statements.

         With respect to the Mallard disposition, the Company is required under
the terms of the Stock Purchase Agreement with Parker to effect various
transfers of assets to Mallard and to make various capital additions to Mallard
prior to the closing.  The Company is also obligated under the Stock Purchase
Agreement to transfer certain assets to Mallard and to release, assume or
satisfy certain liabilities with respect to Mallard.  In addition, the purchase
price with respect to the disposition of Mallard is subject to adjustment based
on various changes in working capital and other assets of Mallard from June 30,
1996, through the date of closing.  The final structure of these transactions
is expected to have an impact on the amount of gain that will be recognized in
the transaction, the amount of taxes and other expenses that may be payable in
connection with the transaction and the net proceeds received by the Company
from the transaction.  While the Company has made various assumptions with
respect to these matters that it believes to be reasonable, it is anticipated
that the actual gain and net proceeds to the Company after giving effect to the
payment of taxes, expenses and charges will vary from those set forth in the
pro forma financial statements.

         The following unaudited pro forma condensed consolidated statements
should be read in conjunction with (i) the Consolidated Financial Statements of
the Company and the related notes thereto, (ii) the historical financial
statements of TCA for the year ended December 31, 1995, and the quarter ended
March 31, 1996, and the related notes thereto, included in the Company's
Current Report on Form 8-K dated June 24, 1996, and (iii) the audited
consolidated financial statements of Prideco for the fiscal year ended June 30,
1995, and related notes filed with the Company's Current Report on Form 8-K/A
dated August 17, 1995, as amended by Amendment No.2 to the Form 8-K/A dated May
7, 1996.

         The historical results of Prideco contained in the unaudited pro forma
condensed consolidated statement of income for the twelve-month period ended
December 31, 1995 reflect only the results of operations for the six-month
period ended June 30, 1995, the date on which the Company acquired Prideco.

         The pro forma information is not necessarily indicative of the results
that might have occurred had the transactions taken place at the beginning of
the periods specified and is not intended to be a projection of future results.

GENERAL

         The following notes set forth the assumptions used in preparing the
unaudited pro forma condensed consolidated financial statements.  The pro forma
adjustments are based on estimates made by the Company's management using
information currently available.  For purposes of preparing these unaudited pro
forma condensed consolidated financial statements, certain assumptions have
been made in allocating the purchase price of TCA to the assets to be acquired
and liabilities to be assumed.  Certain assumptions for the Mallard disposition
have been made in determining the one-time gain after taxes, expenses and
charges related to the disposition.  As a result, the pro forma adjustments
discussed below are subject to change pending the completion of the Mallard
disposition and a detailed evaluation and appraisal of the TCA assets acquired
and a detailed evaluation of liabilities assumed.

PRO FORMA ADJUSTMENTS

         The adjustments to the accompanying unaudited pro forma condensed
consolidated balance sheet as of June 30, 1996, are described below:

         (a)     To adjust the TCA assets acquired to their estimated fair
                 market value and to adjust the TCA liabilities assumed.
         (b)     To reflect the $338 million sale of Mallard for $313 million
                 cash and Parker preferred stock having a value of $25 million
                 and to eliminate the assets and liabilities included in the
                 combined balance sheet of the Company's Mallard business as of
                 June 30, 1996.
         (c)     To record the sale by the Company of 3,450,000 shares of
                 Common Stock at $31-1/8 per share in the 1996 equity offering,
                 after deducting underwriting discounts and commissions and
                 estimated offering expenses of $5.2 million and $0.5 million,
                 respectively.
         (d)     To record the issuance by the Company of 500,000 shares of
                 Common Stock at a price of $30 per share, payment of $14.35
                 million cash and a note for $650,000 for the acquisition of
                 TCA, the repayment of $7.1 million of assumed debt, and to
                 eliminate TCA's historical stockholders' investment.
         (e)     To reflect the Company's August 22, 1996 purchase of two barge
                 rigs operating in Nigeria for $24.5 million cash and a $7.5
                 million drill pipe credit as such rigs have been combined with
                 Mallard's business and are included in the disposition.
         (f)     To record the estimated excess of cost over fair value of net
                 tangible assets of TCA.
         (g)     To record the deferred tax assets of $10.8 million relating to
                 tax benefits of TCA and to record the deferred tax liability
                 of $9.2 million relating to differences in the book and tax
                 basis of the net assets of TCA.
         (h)     To record the assumed reduction of indebtedness of the Company
                 and of TCA through the application of a portion of the net
                 proceeds to the Company from the 1996 equity offering.
         (i)     To reflect an estimated $76.6 million current tax liability
                 associated with the gain from the Mallard sale and to reflect
                 an estimated $24.0 million accrual for transaction costs,
                 transfer of asset costs and liabilities retained by the
                 Company related to the Mallard sale.
         (j)     To reflect an estimated after-tax gain of $80.7 million
                 related to the Mallard disposition.  The amount of gain will
                 be dependent upon various factors, including costs and
                 expenses relating to the transfer of assets to Mallard, the
                 amount of transaction costs and liabilities retained by the
                 Company as part of the Mallard sale and the amount of US,
                 foreign and local taxes that may be payable in connection with
                 the disposition.  Although the Company believes that the above
                 estimated after-tax gain reflects a reasonable estimation of
                 such gain, the actual gain after taxes, expenses and charges
                 relating to the disposition is currently expected to be
                 between $75 million and $85 million and the net cash proceeds
                 to the Company after giving effect to the payment of taxes,
                 expenses and charges relating to the disposition is currently
                 expected to be between $235 million and $245 million.

                            STOCK PURCHASE AGREEMENT


         This STOCK PURCHASE AGREEMENT, dated as of September 14, 1996 (the
"Agreement") is by and among PARKER DRILLING COMPANY, a Delaware corporation
("Parker") and ENERGY VENTURES, INC., a Delaware corporation ("EVI").  Parker
and EVI are referred to collectively herein as the "Parties," and each
individually as a "Party."  EXHIBIT A sets forth the definitions of certain
terms used herein.

                                   RECITALS:

         WHEREAS, EVI beneficially and of record owns all of the outstanding
capital stock of  Mallard Bay Drilling, Inc., a Louisiana corporation
("Mallard"), which is engaged in the contract drilling business;

         WHEREAS, subject to and in accordance with the terms of this
Agreement, Parker wishes to purchase from EVI, and EVI wishes to sell to
Parker, all of the outstanding shares of capital stock of Mallard; 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 purchase and sale of the shares of the
capital stock of Mallard;

         Now, therefore, in consideration of the premises and the mutual
promises herein made, and in consideration of the representations, warranties,
and covenants herein contained, the Parties agree as follows:

         1.      PURCHASE AND SALE OF MALLARD STOCK.

         (a)     BASIC TRANSACTION.  On and subject to the terms and conditions
of this Agreement, Parker agrees to purchase from EVI, and EVI agrees to sell
to Parker, all of the issued and outstanding shares of capital stock of Mallard
for the consideration specified in this Section 1.

         (b)     PURCHASE PRICE.  Parker agrees to deliver to EVI at the
Closing (as defined below) (i) the Estimated Amount (as defined below) in cash
by wire transfer into an account designated by EVI at least one business day
before Closing, and (ii) a number of shares of a newly created series of
preferred stock of Parker, par value $1.00 per share, which shall be designated
the "Parker Series D Convertible Preferred Stock" ("Series D Preferred Stock")
with a Market Value of $25,000,000.  The form of certificate of designations of
the Series D Preferred Stock is attached hereto as EXHIBIT B.  For purposes of
this Agreement, the "Market Value" of the Series D Preferred Stock shall equal
the average of the last reported sales price on the New York Stock Exchange
composite index for the common stock, par value $.16 2/3 per share, of Parker
("Parker Common Stock") for the ten trading days ending two Business Days
before the Closing Date (as defined below).  The cash payment and shares of
Series D Preferred Stock to be delivered to EVI,
<PAGE>   2
by Parker at the Closing pursuant to this Section 1(b) are referred to
collectively herein as the "Purchase Price."  The "Estimated Amount" shall mean
$313,000,000 plus or minus the Estimated Adjustment.  The "Estimated
Adjustment" shall be an amount equal to the difference between $161,901,000 and
the estimated Net Assets (as defined in Section 1(f)(1)) as of the Closing Date
based on the latest available balance sheet ("Pre-Closing Balance Sheet") for
the Contract Drilling Business (as defined below) prepared in accordance with
GAAP and on the same basis as the Most Recent Balance Sheet (as defined in
Section 2(e)(3)).  EVI shall advise Parker of the amount of the Estimated
Amount no later than five Business Days prior to the Closing Date and shall
provide to Parker a copy of the Pre-Closing Financial Statements and the
calculations used by EVI in arriving at the Estimated Amount.

         (c)     THE CLOSING.  The closing of the transactions contemplated by
this Agreement (the "Closing") shall take place at the offices of Vinson &
Elkins L.L.P., Suite 2300, 1001 Fannin, Houston, Texas 77002-6760, commencing
at 9:00 a.m. local time on the second Business Day following the satisfaction
or waiver of all conditions to the obligations of the Parties to consummate the
transactions contemplated hereby (other than conditions with respect to actions
the respective Parties will take at the Closing itself) or such other date as
the Parties may mutually determine (the "Closing Date").

         (d)     DELIVERIES AT THE CLOSING.  At the Closing, (i) EVI will
deliver to Parker the various certificates, instruments, and documents referred
to in Section 6(a), (ii) Parker will deliver to EVI the various certificates,
instruments, and documents referred to in Section 6(b), (iii) EVI will deliver
to Parker stock certificates representing all of the issued and outstanding
shares of capital stock of Mallard, endorsed in blank or accompanied by duly
executed stock powers, and (iv) Parker will deliver to EVI the consideration
specified in Section 1(b).

         (e)     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 transactions contemplated hereby as
promptly as possible.  If, at any time after the Closing Date, any such further
action is necessary to carry out the purposes of this Agreement, EVI shall, and
shall direct its representatives to, take all such lawful and necessary action.

         (f)     ADJUSTMENTS TO THE PURCHASE PRICE.  Parker and EVI agree that
in the event that the Net Assets (as defined and subject to the adjustments
described below) attributable to the contract drilling business and related
operations of Mallard and the other subsidiaries of EVI on a combined basis
(the "Contract Drilling Business") as of the Closing Date are greater or lesser
than $161,901,000, the Purchase Price shall be increased or decreased, as the
case may be, by an amount equal to the difference between the actual Net Assets
and $161,901,000, in the manner set forth herein.

                 (1)      On or before a date that is 90 days following the
         Closing (or the next Business Day if such day is not a Business Day),
         Parker will prepare and deliver to EVI a statement (the "Closing
         Balance Sheet") showing the actual amount of assets and liabilities
         attributable to the Contract Drilling Business as of the Closing Date,
         prepared in accordance with GAAP and on the same basis as the Most
         Recent Balance Sheet.  For




                                     -2-
<PAGE>   3
         purposes of this Agreement, "Net Assets" shall mean the difference
         between (i) total assets excluding any intercompany receivables, and
         (ii) total liabilities excluding any intercompany liabilities (other
         than those for drill pipe, tubulars and related products purchased
         after the date hereof in the Ordinary Course of Business at
         arm's-length market prices) and deferred income tax liabilities, each
         prepared in accordance with GAAP and on the same basis as the Most
         Recent Balance Sheet; provided, however, that the following
         adjustments shall be made in the calculation of Net Assets on the
         Closing Balance Sheet: the amount of assets shall be decreased by the
         book value of the upgrade to Rig 74 contemplated by Section 4(l)
         hereof or funds advanced in respect thereof.  In addition, the Parties
         agree that to the extent the carrying value of the total assets is
         overstated or the carrying value of the total liabilities is
         understated on the Most Recent Balance Sheet, no adjustment to such
         values shall be made in the Closing Balance Sheet unless the aggregate
         value of such revisions to the carrying value of the assets and
         liabilities on the Most Recent Balance Sheet exceeds $2,500,000, and
         in such case only to the extent that such revisions exceed $2,500,000.

                 (2)      Within 30 days following delivery of the Closing
         Balance Sheet, EVI shall notify Parker whether it agrees with such
         statement; provided, however, that if EVI shall fail to so notify
         Parker within such 30-day period, EVI shall be deemed to have agreed
         with such statements.  If EVI disagrees with such statements, EVI and
         Parker shall work in good faith to reach agreement on such statements;
         but if they shall not agree within 10 days the matter will be referred
         to one of the "Big Six" independent public accounting firms as EVI and
         Parker may mutually agree, the costs of which shall be borne equally
         by EVI and Parker.  Such accountants shall examine the records of the
         Contract Drilling Business and determine the disputed Closing Balance
         Sheet items within 30 days following the date such matter is referred
         to them, and such determination shall be final and binding on Parker
         and EVI, and may be enforced by appropriate judicial or other
         proceedings.

                 (3)      If, as so determined, the Net Assets reflected on the
         Closing Balance Sheet exceed $161,901,000, then Parker will within ten
         Business Days of such determination make a cash payment to EVI in an
         amount equal to the excess of the amount of the Net Assets over
         $161,901,000, as an adjustment to the Purchase Price.  If the Net
         Assets as reflected on the Closing Balance Sheet are less than
         $161,901,000, then EVI shall within ten Business Days of such
         determination make a cash payment to Parker in an amount equal to the
         excess of $161,901,000 over the Net Assets on such date, as an
         adjustment to the Purchase Price.  The amount of any Estimated
         Adjustment paid shall be credited against any amount payable pursuant
         to this paragraph (3).

         2.      REPRESENTATIONS AND WARRANTIES OF EVI.  EVI represents and
warrants to Parker that the statements contained in this Section 2 are true,
correct and complete as of the date of this Agreement and will be true, correct
and complete as of the Closing Date (as though made then and as though the
Closing Date were substituted for the date of this Agreement throughout this
Section 2, except for representations that are made effective as of a specific
date, which shall be true, correct and complete as of such date), except as set
forth in the Schedule applicable to such representation and warranty contained
in the disclosure schedule delivered by EVI to Parker on

Rights Agreement by EVI and the consummation of the transactions contemplated
hereby and thereby have been duly authorized by all necessary corporate action
and no other corporate action on the part of EVI, including any action by the

and constitutes the valid and legally binding obligation of EVI enforceable
against EVI in accordance with its terms, and the Registration Rights

filing with, or to obtain any authorization, consent, or approval of any
Governmental Authority in order to consummate the transactions contemplated by

in each jurisdiction in which the nature of the business conducted by them or
the ownership or leasing of their properties makes such qualification

would not have a Material Adverse Effect.  Mallard and its subsidiaries are in
possession of all certifications, franchises, authorizations, licenses,
permits, approvals and orders of any Governmental Authority (collectively,
"Permits") necessary to own, lease and operate their properties and to carry on
their businesses as currently conducted, except for such Permits the failure of
which to obtain would not, individually or in the aggregate, have a Material
Adverse Effect, and there is no action, proceeding or investigation pending, or
to the knowledge of EVI, threatened, regarding the suspension or cancellation
of any of the Permits, except for those actions, proceedings or investigations
that would not, individually or in the aggregate, have a Material Adverse
Effect.  EVI has delivered to Parker correct and complete copies of the
charters and bylaws of Mallard and its subsidiaries, each as amended to date.
The minute books (containing the records of meetings of the stockholders, the
board of





                                      -4-

other contracts or commitments relating to any capital stock or other security
of Mallard (other than this Agreement).  There are no outstanding or authorized

material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; provided, however, that EVI makes no
representation or warranty as to misstatements or omissions in the EVI
Commission Filings that relate solely to businesses other than the Contract
Drilling Business and would be immaterial to a purchaser of the Contract
Drilling Business.

         (2)     All of the consolidated financial statements included in the
EVI Commission Filings (including any related notes or schedules) were prepared
in accordance with GAAP applied on a consistent basis (except as may be noted
therein) and complied in all material respects with all applicable rules of the
Commission.  Such consolidated financial statements fairly present the
consolidated financial position of EVI and its subsidiaries 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 interim financial
statements to normal year-end audit adjustments on a basis comparable with past
periods).

         (3)     Set forth in Schedule 2(e) are the following unaudited
consolidated financial statements of the Contract Drilling Business presented
on a combined basis (the "Mallard Unaudited Financial Statements"):  (i)
unaudited balance sheets and income statement as of and for each of the years
ended December 31, 1991, 1992, 1993, 1994 and 1995; (ii) an unaudited balance
sheet and income statement as of and for the six months ended June 30, 1996 and
(iii) an unaudited balance sheet as of July 31, 1996 (the "Most Recent Balance
Sheet").  The Mallard Unaudited Financial Statements were prepared in
accordance with GAAP applied on a consistent basis for financial statements of
an operating division of EVI (except as noted therein) and fairly present in
all material respects the financial position of the Contract Drilling Business
as of the dates thereof and the results of operations for the periods then
ended (subject to the qualifications described therein).  The "intercompany
debt" line item on the Most Recent Balance Sheet includes all intercompany
accounts payable or other amounts owing to EVI or any of its affiliates,
including accounts payable with respect to the purchase of drill pipe, tubulars
or other oilfield equipment or services.

         (f)     EVENTS SUBSEQUENT TO MOST RECENT QUARTER END.  Except as set
forth on Schedule 2(f), since June 30, 1996 there has not been any change in
the conduct of the ongoing business operations of the Contract Drilling
Business that would, individually or in the aggregate, have a Material Adverse
Effect (other than those changes affecting the oil and gas industry or the
drilling and workover segment thereof in general).  Without limiting the
generality of the foregoing, except as set forth in Schedule 2(f), since that
date to the date hereof, Mallard and the other subsidiaries of EVI with respect
to their operations constituting a part of the Contract Drilling Business have
not:

                 (13)     committed to do any of the foregoing.

         (g)     LEGAL COMPLIANCE; NONCONTRAVENTION.  Except as set forth in
Schedule 2(g), Mallard and its subsidiaries have complied with and are not in
violation of or default under (i) any Law applicable to them or their
properties or (ii) any Permits, except for such events of noncompliance,

contemplated hereby will not, (x) conflict with or violate the charter or
bylaws of either EVI, Mallard or the subsidiaries of Mallard, (y) conflict with

Permit or other instrument or obligation to which Mallard or any of its
subsidiaries is a party or by which Mallard or any of its subsidiaries or their
properties are bound or subject to, except in the case of clauses (y) and (z)
for conflicts, violations, breaches, defaults, events, rights of termination,
amendment, acceleration or cancellation, payment obligations or Security
Interests that would not, individually or in the aggregate, have a Material
Adverse Effect.

         (h)     TITLE TO PROPERTIES.  Except as disclosed in the Financial
Statements or on Schedule 2(h), Mallard and its subsidiaries have good and

received any notice of infringement or notice of conflict with the asserted
rights of others in such patents, trademarks, trade names, and copyrights; nor
are EVI or Mallard and its subsidiaries

existing, and in good standing under the laws of Delaware.

         (b)     AUTHORIZATION OF TRANSACTION.  Parker has all requisite power
and authority to execute and to deliver this Agreement and the Registration
Rights Agreement and to perform its obligations hereunder and thereunder and to
consummate the transactions contemplated hereby and thereby.  The execution and
delivery of this Agreement and the Registration Rights Agreement by Parker and
the consummation of the transactions contemplated hereby and thereby have been
duly authorized by all necessary corporate action and no other corporate action
on the part of Parker, including any action by the stockholders of Parker, is
necessary to authorize this Agreement or the Registration Rights Agreement or
to consummate the transactions contemplated hereby and thereby (other than
adoption by the Board of Directors of Parker of the Certificate of Designations
for the Series D Convertible Preferred Stock and the filing of such Certificate
of Designations with the Delaware Secretary of State).  This Agreement has been
duly executed and delivered by Parker and constitutes the valid and legally
binding obligation of Parker, enforceable in accordance with its terms, and the
Registration Rights Agreement, when executed and delivered by each party
thereto, will constitute the valid and legal binding obligation of Parker
enforceable in accordance with its terms.  Except as required under the
Hart-Scott-Rodino Act or as otherwise provided herein, Parker need not give
any notice to, make any filing with, or obtain any authorization, consent, or
approval of any Governmental Authority in order to consummate the transactions
contemplated by this Agreement other than those that the failure to obtain
would not, individually or in the aggregate, have a Material Adverse Effect.

         (c)     POWER AND AUTHORITY.  Parker has all requisite corporate or
other power and authority to own, lease and operate its properties and to carry
on its business as each is now being conducted.

         (d)     CAPITALIZATION.  The entire authorized capital stock of Parker
consists of 70,000,000 shares of Parker Common Stock and 1,942,000 shares of
preferred stock, par value $1.00 per share ("Parker Preferred Stock").  As of
the date hereof there are 65,334,528 shares of Parker Common Stock outstanding
and no shares of Parker Preferred Stock outstanding.  The shares of Series D
Preferred Stock to be issued to EVI on the Closing Date pursuant to the
transactions contemplated hereby will be validly issued, fully paid and
nonassessable.

         (e)     COMMISSION FILINGS; FINANCIAL STATEMENTS.

         (1)     Parker has filed all reports, proxy statements, registration
statements and other documents, together with any amendments required to be
made with respect thereto, required to be filed with the Commission under the
Exchange Act.  All such reports, proxy statements, registration statements and
other documents (including all exhibits thereto and all documents incorporated
by reference therein) filed by Parker with the Commission since January 1,
1995, together with any amendments thereto, are referred to herein as the
"Parker Commission Filings."  Parker has delivered to EVI copies of the Parker
Commission Filings.  As of the respective dates of their filing with the
Commission, the Parker Commission Filings complied in all material respects
with the Exchange Act, the Securities Act and the rules and regulations of the





                                      -18-

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 therein, in light of the circumstances under
which they were made, not misleading.

         (2)     All of the consolidated financial statements included in the
Parker Commission Filings (including any related notes or schedules) were
prepared in accordance with GAAP applied on a consistent basis (except as may
be noted therein) and complied in all material respects with all applicable
rules of the Commission.  Such consolidated financial statements fairly present
the consolidated financial position of Parker and its subsidiaries as of the
dates thereof and the results of operations, cash flows and changes in
shareholders' equity for the periods then ended (subject in the case of interim
financial statements to normal year-end audit adjustments on a basis comparable
with past periods).

         (f)     EVENTS SUBSEQUENT TO MOST RECENT QUARTER END.  Since June 30,
1996 there has not been any change in the conduct of the ongoing business
operations of Parker and its subsidiaries that would, individually or in the
aggregate, have a Material Adverse Effect (other than changes affecting the oil
and gas industry or the drilling and workover segment thereof in general).

         (g)     LEGAL COMPLIANCE; NONCONTRAVENTION.   The execution and
delivery of this Agreement and the Registration Rights Agreement by Parker does
not, and the consummation of the transactions contemplated hereby and thereby
(including the issuance and redemption of the Series D Preferred Stock under
the terms thereof) will not, (i) conflict with or violate the certificate of
incorporation or bylaws of Parker, (ii) conflict with or violate any Law, or
(iii) result in any breach of or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
or require payment under, or result in the creation of a Security Interest on
any properties or assets of Parker pursuant to any note, bond, mortgage,
indenture, contract, agreement, lease, Permit or other instrument or obligation
to which Parker or any of its subsidiaries is a party or by which Parker or any
of its subsidiaries or their properties are bound or subject to, except that
consummation of the transactions will require consents under Parker's bank
credit facilities and except for breaches, defaults, events, rights of
termination, amendment, acceleration or cancellation, payment obligations or
Security Interests that would not, individually or in the aggregate, have a
Material Adverse Effect or affect the validity or prohibit the issuance of the
Series D Preferred Stock.

         (h)     BROKERS' FEES.  Parker shall not have any liability to pay any
fees or commissions to any broker, finder, or agent with respect to the
transactions contemplated by this Agreement for which EVI could become liable
or obligated.

         (g)     NO SOLICITATION.  From and after the date of this Agreement
until the termination of this Agreement in accordance with its terms, neither
EVI nor any of its subsidiaries, nor any officer, director, employee, agent or
representative of EVI or any of its subsidiaries, shall, directly or
indirectly, solicit or encourage, including by way of furnishing information,
the initiation of any inquiries or proposals regarding, or engage in or
continue any discussions or enter into any agreements regarding, any merger,
tender offer, sale of shares of capital stock or similar business combination
transactions involving any or all of the Contract Drilling Business, or any
sale of all or substantially all the assets of the Contract Drilling Business,
other than in connection with the transaction with Parker contemplated herein;
provided, however, that EVI or its officers, directors, employees, agents or
representatives may furnish information with respect to the Contract Drilling
Business in connection with any inquiry or proposal or discussions relating to
a merger, tender offer, sale of shares of capital stock or similar business
combination transaction involving EVI, or any sale of all or substantially all
of the assets of EVI, provided that no such discussions or agreements resulting
therefrom shall in any manner conflict with the terms of this Agreement and





                                      -22-

notice to each other party to such discussions that EVI is party to a valid and
legally binding agreement with Parker with respect to the Contract Drilling
Business.

         (h)     INSURANCE MATTERS.  EVI shall use its reasonable efforts to

the historical tax, accounting or financial records of EVI, (ii) the accounting
and management information systems and software of EVI used in connection with
the business of Mallard, (iii) the subsidiaries of EVI whose assets may be
transferred to Mallard or its subsidiaries pursuant to this section, or (iv)

retained by EVI or its subsidiaries other than Mallard and its subsidiaries.
After the Closing, EVI will provide Parker with access to such historical
accounting and other records relating to the business of Mallard and its
subsidiaries prior to Closing to the extent reasonably necessary to assist
Parker in making its tax, regulatory, Exchange Act and related filings.

         (j)     REGISTRATION RIGHTS.  At the Closing, Parker and EVI shall
enter into a registration rights agreement in substantially the form attached
hereto as EXHIBIT D ("Registration Rights Agreement").

         (k)     AUDITED FINANCIAL STATEMENTS.  EVI shall use its best efforts
to deliver to Parker within 20 days after the date hereof, and shall in any
event deliver to Parker within 30 days after the date hereof, audited financial
statements for Mallard and its consolidated subsidiaries, together with the
Contributed Assets, accompanied by a report of EVI's independent public
accountants, consisting of balance sheets and statements of income, cash flows
and stockholders' equity as of and for each of the years ended December 31,
1993, 1994 and 1995 (the "Mallard Audited Financial Statements").  The Mallard
Audited Financial Statements will be prepared in accordance with GAAP applied
on a consistent basis (except as may be noted therein) and will fairly present

dates thereof and the results of operations, cash flows and changes in
stockholders' equity for the periods then ended.

         (l)     RIG UPGRADE.  Prior to Closing, EVI shall complete the rig
modification and upgrade to Rig 74 as described on Schedule 4(l) (the "Rig

         (1)     Parker shall promptly after the date of this Agreement
initiate and diligently pursue action to obtain financing in an amount
necessary to permit Parker to pay the cash portion of the Purchase Price. In
such connection, Parker plans to effect a private placement of debt and Parker
agrees to use its commercially reasonable efforts to complete such placement.

         (2)     Parker shall keep EVI informed from time to time as to the
status of the financing contemplated by subsection (1) of this Section 4(m) and

         5.      POST-CLOSING COVENANTS.  The Parties agree as follows with
respect to the period following the Closing.

         (a)     GENERAL.  In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
each of the Parties will take such further action (including the execution and
delivery of such further instruments and documents) as the other Party
reasonably may request; provided, however, that this Section 5(a) shall not be
deemed to require either party to expend funds or to incur obligations not
otherwise expressly required pursuant to the Agreement.

         (b)     LITIGATION SUPPORT.  In the event and for so long as any Party
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving Mallard and its subsidiaries, each of the other
Parties will cooperate with it and its counsel in the contest or defense, make
available their personnel, and provide such testimony and access to their books
and records as shall be necessary in connection with the contest or defense,
all at the sole cost and expense of the contesting or defending Party (unless
the contesting or defending Party is entitled to indemnification therefor under
Section 7).

effect the listing on the New York Stock Exchange of the shares of Parker
Common Stock issuable upon conversion of the Series D Preferred Stock.

         (d)     AUTHORIZATION OF COMMON STOCK.  Parker agrees that at its next

to January 31, 1997, it will propose an amendment to its Restated Certificate
of Incorporation to increase the number of authorized shares of Parker Common
Stock to at least 80,000,000 shares.  The Board of Directors of Parker will
recommend to Parker's stockholders that they vote in favor of any such proposal
to increase Parker's authorized shares, and Parker will use its best efforts to
solicit proxies in favor of such proposal.

         (e)     VOTING OF SERIES D PREFERRED STOCK.  If the Closing shall have
occurred prior to the stockholders meeting to approve the increase in the
authorized shares of Common Stock, EVI agrees to vote the shares of Series D
Preferred Stock in favor of the proposal.

         (b)     INDEMNIFICATION PROVISIONS FOR BENEFIT OF PARKER.  EVI shall
defend, indemnify and hold Parker harmless from and against any and all Adverse
Consequences resulting from or arising out of (i) any breach or nonperformance,
either partial or total, of any representation, warranty, covenant or agreement
of EVI in this Agreement (provided, however, that EVI shall have no obligation

Consequence resulting from or arising out of a breach of any representation or
warranty of EVI in this Agreement unless EVI receives notice of such Adverse
Consequence within the applicable Survival Period), (ii) violations or alleged

<PAGE>   28
from or arising out of (i) the breach or non-performance, either partial or

guarantees of debt of Mallard or any of its subsidiaries by EVI or performance

identified to Parker five Business Days prior to the Closing Date; provided,
however, that Parker shall have no obligation to indemnify, defend or hold EVI
harmless with respect to any Adverse Consequences resulting from or arising out
of a breach of any representation or warranty of Parker in this Agreement
unless Parker receives notice of such Adverse Consequence within the applicable
Survival Period.

         (d)     MATTERS INVOLVING THIRD PARTIES.

         (1)     If any third party shall notify any Party (the "Indemnified
Party") with respect to any matter (a "Third Party Claim") that may give rise
to a claim for indemnification against any other Party (the "Indemnifying
Party") under this Section 7, then the Indemnified Party shall promptly notify
the Indemnifying Party thereof in writing; provided, however, that no delay on
the part of the Indemnified Party in notifying the Indemnifying Party shall
relieve the Indemnifying Party from any obligation hereunder unless (and then
solely to the extent) the Indemnifying Party is prejudiced thereby.  For
purposes of this Section 7(d), matters relating to Taxes that are addressed in
Section 8 shall not be deemed to be a Third Party Claim.

         (2)     The Indemnifying Party will have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice
reasonably satisfactory to the Indemnified Party so long as (A) the
Indemnifying Party notifies the Indemnified Party in writing within 30 days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences the Indemnified Party may suffer resulting
from, arising out of, relating to, in the nature of, or caused by the Third
Party Claim; and (B) the Indemnifying Party conducts the defense of the Third
Party Claim actively and diligently.

         (3)     So long as the Indemnifying Party is conducting the defense of
the Third Party Claim in accordance with Section 7(d)(2), (A) the Indemnified
Party may retain separate co-counsel at its sole cost and expense and
participate in the defense of the Third Party Claim, (B) the Indemnified Party
will not consent to the entry of any judgment or enter into any settlement with
respect to the Third Party Claim without the prior written consent of the
Indemnifying Party; and (C) the Indemnifying Party will not consent to the
entry of any judgment or enter into any settlement with respect to the Third
Party Claim without the prior written consent of the Indemnified Party (which
consent will not be withheld unreasonably).

         (4)     In the event any of the conditions in Section 7(d)(2) is or
becomes unsatisfied, however, (A) the Indemnified Party may defend against the
Third Party Claim in any manner it reasonably may deem appropriate; provided,
however, that the Indemnified Party shall not consent to the entry of any
judgment or enter into any settlement or agreement to settle a Third Party
Claim without the prior written consent of the Indemnifying Party which consent
shall not be





                                      -28-
<PAGE>   29
unreasonably withheld; (B) the Indemnifying Party will reimburse the
Indemnified Party promptly and periodically for the costs of defending against
the Third Party Claim (including reasonable attorneys' fees and expenses); and
(C) the Indemnifying Party will remain responsible for any Adverse Consequences
the Indemnified Party actually suffers resulting from, arising out of, relating
to, in the nature of, or caused by the Third Party Claim to the fullest extent
provided in this Section 7.

         (e)     EXPRESS NEGLIGENCE.  THE INDEMNIFICATION AGREEMENTS OF THE
PARTIES HEREIN SHALL APPLY NOTWITHSTANDING THE CIRCUMSTANCES RELATING TO SUCH
INDEMNITY MAY RELATE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE, GROSS
NEGLIGENCE, WILLFUL MISCONDUCT OR VIOLATION OF LAW BY ANY INDEMNIFIED PARTY,
ITS SUBSIDIARIES, OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS.

         8.      TAX MATTERS.  The Parties agree as follows with respect to the
period following the Closing:

         (a)     SECTION 338(H)(10) ELECTIONS.  EVI agrees that, if requested
by Parker prior to the Closing, EVI, as the common parent of the affiliated
group of corporations filing a consolidated federal income Tax Return which
includes Mallard and its subsidiaries (the "EVI Group"), shall join Parker in
making an election under section 338(h)(10) of the Code and a similar election
under any applicable state income Tax law (collectively, the "Section
338(h)(10) elections") with respect to Parker's purchase of the Mallard Common
Stock.  If Parker determines prior to the Closing to make the Section
338(h)(10) elections with respect to its purchase of the Mallard Common Stock,
on or before the Closing Date Parker and EVI shall cause Internal Revenue
Service Form 8023A and any similar forms under applicable state income Tax law
(the "Forms") with respect to Parker's purchase of the Mallard Common Stock to
be duly executed by an authorized person for Parker and EVI, respectively.
Parker and EVI shall cooperate in good faith with each other in completing the
Forms and schedules required to be attached thereto, and Parker shall provide a
copy of the executed Forms and schedules to EVI and Parker shall duly and
timely file the Forms as prescribed by Treasury Regulation Section
1.338(h)(10)-1 or the corresponding provision of applicable state income Tax
law as soon as practicable after the Closing and shall promptly thereafter
provide EVI with evidence of each such filing.

         (b)     PREPARATION AND FILING OF TAX RETURNS.  (1) With respect to
each Tax Return covering a taxable period ending on or before the Closing Date
that is required to be filed after the Closing Date for, by or with respect to
Mallard or any subsidiary of Mallard (other than the Tax Returns described in
Section 8(a)(3)), EVI shall cause such Tax Return to be prepared, shall cause
to be included in such Tax Return all items of income, gain, loss, deduction
and credit or other items (collectively "Tax Items") required to be included
therein, and shall deliver the original of such Tax Return to Parker at least
30 days prior to the due date (including extensions) of such Tax Return.  If
the amount of the Tax shown to be due on such Tax Return exceeds the amount
reflected as a current liability for such Tax on the Closing Balance Sheet, EVI
shall pay to Parker the amount of such excess not less than 5 days prior to the
due date of such Tax Return.  Parker shall cause Mallard or the respective
subsidiary of Mallard to file timely such Tax Return with the appropriate
taxing authority and to pay the amount of Taxes shown to be due on such Tax
Return.





                                      -29-
<PAGE>   30
         (2)     With respect to each Tax Return covering (i) a taxable period
beginning on or before the Closing Date and ending after the Closing Date or,
(ii) a taxable period beginning after the Closing Date, that is required to be
filed after the Closing Date for, by or with respect to Mallard or any
subsidiary of Mallard (other than the Tax Returns described in Section
8(b)(3)), Parker shall cause such Tax Return to be prepared and shall cause to
be included in such Tax Return all Tax Items required to be included therein.
Parker shall determine (by an interim closing of the books as of the Closing
Date except for ad valorem Taxes and franchise Taxes based on capital which
shall be prorated on a daily basis) the portion, if any, of the Tax due with
respect to the period covered by such Tax Return which is attributable to
Mallard or the respective subsidiary of Mallard for a Pre-Closing Taxable
Period.  At least 30 days prior to the due date (including extensions) of such
Tax Return, Parker shall deliver to EVI a copy of such Tax Return and of its
determinations.  If the amount of Tax so determined to be attributable to the
Pre-Closing Taxable Period exceeds the amount reflected as a current liability
for such Tax on the Closing Balance Sheet, EVI shall pay to Parker the amount
of such excess Tax not less than 5 days prior to the due date of such Tax
Return.  Parker shall cause Mallard or the respective subsidiary of Mallard to
file timely such Tax Return with the appropriate taxing authority and to pay
timely the amount of Taxes shown to be due on such Tax Return.

         (3)     EVI shall cause to be included in the consolidated federal
income Tax Returns (and the state income Tax Returns of any state that permits
consolidated, combined or unitary income Tax Returns, if any) of any group of
corporations that includes EVI and Mallard or any subsidiary of Mallard (the
"EVI Group") for all periods ending on or before or which include the Closing
Date, all Tax Items of Mallard and the subsidiaries of Mallard which are
required to be included therein, shall file timely all such Tax Returns with
the appropriate taxing authorities and shall pay timely all Taxes due with
respect to the periods covered by such Tax Returns.

         (4)     Any Tax Return to be prepared pursuant to the provisions of
this Section 8 shall be prepared in a manner consistent with practices followed
in prior years with respect to similar Tax Returns, except for changes required
by changes in law.

         (c)     ACCESS TO INFORMATION.  (1) EVI and each member of the EVI
Group shall grant to Parker (or its designees) access at all reasonable times
to all of the information, books and records relating to Mallard and the
subsidiaries within the possession of EVI or any member of the EVI Group
(including workpapers and correspondence with taxing authorities), and shall
afford Parker (or its designees) the right (at Parker's expense) to take
extracts therefrom and to make copies thereof, to the extent reasonably
necessary to permit Parker (or its designees) to prepare Tax Returns, to
conduct negotiations with Tax authorities, and to implement the provisions of,
or to investigate or defend any claims between the parties arising under, this
Agreement.

         (2)     Parker shall grant or cause Mallard and its subsidiaries to
grant to EVI (or its designees) access at all reasonable times to all of the
information, books and records relating to Mallard and its subsidiaries within
the possession of Parker, Mallard or the subsidiaries of Mallard (including
workpapers and correspondence with taxing authorities), and shall afford EVI
(or its designees) the right (at EVI's expense) to take extracts therefrom and
to make copies thereof, to





                                      -30-
<PAGE>   31
the extent reasonably necessary to permit EVI (or its designees) to prepare Tax
Returns, to conduct negotiations with Tax authorities, and to implement the

         (1)     a claim, notice of deficiency, or assessment by, or any
obligation owing to, any taxing authority for:

                 (A)      any Taxes of Mallard or any subsidiary of Mallard
         attributable to any Pre-Closing Taxable Period in excess of Taxes
         reflected as current liabilities on the Closing Balance Sheet;

                 (B)      any Taxes of any corporation (other than Mallard and
         any subsidiaries of Mallard) that is or was a member of a Seller
         Affiliated Group prior to Closing; and

                 (C)      any Taxes resulting from the Section 338(h)(10)
         elections;

                 (D)      any Taxes of EVI, Mallard or their subsidiaries

         (2)     any breach of any representation, warranty or obligation of
EVI under Section 2(o) or Section 8 of this Agreement.

         (e)     INDEMNIFICATION PROVISIONS FOR THE BENEFIT OF EVI.  Parker
agrees to defend, indemnify and hold harmless EVI from and against, and agrees
to pay, all Tax Losses incurred as a result of:

                 (1)      a claim, notice of deficiency, or assessment by, or
         any obligation owing to, any taxing authority for any Taxes of Mallard

         Period; and





                                      -31-
<PAGE>   32
                 (2)      any breach of any representation, warranty or
         obligation of Parker under Section 8 of this Agreement.

         (f)     INDEMNIFICATION PROCEDURES.  (1) If a claim shall be made by
any taxing authority that, if successful, would result in the indemnification
of a party under this Agreement (referred to herein as the "Tax Indemnified
Party"), the Tax Indemnified Party shall promptly notify the party obligated
under this Agreement to so indemnify (referred to herein as the "Tax
Indemnifying Party") in writing; provided, however, that no delay on the part
of the Tax Indemnified Party in notifying the Tax Indemnifying Party shall
relieve the Tax Indemnifying Party from any obligation hereunder unless (and
then solely to the extent ) the Tax Indemnifying Party is prejudiced thereby.

         (2)     The Tax Indemnified Party shall take such action in connection
with contesting such claim as the Tax Indemnifying Party shall reasonably
request in writing from time to time, including the selection of counsel and
experts and the execution of powers of attorney, provided that (A) within 30
days after the notice described in Section 8(f)(1) has been delivered (or such
earlier date that any payment of Taxes is due by the Tax Indemnified Party but
in no event sooner than 5 days after the Tax Indemnifying Party's receipt of
such notice), the Tax Indemnifying Party requests that such claim be contested,
(B) the Tax Indemnifying Party shall have agreed to pay to the Tax Indemnified
Party all costs and expenses that the Tax Indemnified Party incurs in
connection with contesting such claim, including, without limitation,
reasonable attorneys' and accountants' fees and disbursements, and (C) if the
Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax
claimed and sue for a refund, the Tax Indemnifying Party shall have advanced to
the Tax Indemnified Party, on an interest-free basis, the amount of such claim.
The Tax Indemnified Party shall not make any payment of such claim for at least
30 days (or such shorter period as may be required by applicable law) after the
giving of the notice required by Section 8(f)(1), shall give to the Tax
Indemnifying Party any information reasonably requested relating to such claim,
and otherwise shall cooperate with the Tax Indemnifying Party in good faith in
order to contest effectively any such claim.

         (3)     Subject to the provisions of Section 8(f)(2), the Tax
Indemnified Party shall enter into a settlement of such contest with the
applicable taxing authority or prosecute such contest to a determination in a
court or other tribunal of initial or appellate jurisdiction, all as the Tax
Indemnifying Party may request.

         (4)     If, after actual receipt by the Tax Indemnified Party of an
amount advanced by the Tax Indemnifying Party pursuant to Section 8(f)(2)(C),
the extent of the liability of the Tax Indemnified Party with respect to the
claim shall be established by the final judgment or decree of a court or other
tribunal or a final and binding settlement with an administrative agency having
jurisdiction thereof, the Tax Indemnified Party shall promptly repay to the Tax
Indemnifying Party the amount advanced to the extent of any refund received by
the Tax Indemnified Party with respect to the claim together with any interest
received thereon from the applicable taxing authority and any recovery of legal
fees from such taxing authority, net of any Taxes as are required to be paid by
the Tax Indemnified Party with respect to such refund, interest or legal fees
(calculated at the maximum applicable statutory rate of Tax without regard to
any other Tax Items).  Notwithstanding the foregoing, the Tax Indemnified Party
shall not be required to make any





                                      -32-
<PAGE>   33
payment hereunder before such time as the Tax Indemnifying Party shall have
made all payments or indemnities then due with respect to the Tax Indemnified
Party pursuant to this Agreement.

         (5)     Promptly after a final determination the Tax Indemnifying
Party shall pay to the Tax Indemnified Party the amount of any Tax Losses to
which the Tax Indemnified Party may become entitled by reason of the provisions
of this Section 8.

         (g)     REFUNDS.  (1) Any refund (whether by payment, credit, offset
or otherwise) of Taxes described in or covered by Section 8(d) (inclusive of
any interest thereon), regardless of whether such Taxes were paid before, on or
after the Closing Date, shall be the property of EVI and shall be retained by
EVI (or, if applicable, paid or caused to be paid by Parker to EVI, within 15
calendar days after receipt, if any such refund (or interest thereon) is
received by Parker, Mallard or any of the subsidiaries of Mallard, whether by
payment, credit, offset or otherwise).  If there is an adjustment to any such
refund (or interest thereon), any payment or payments theretofore made between
the parties hereto with respect to such refund (or interest thereon) pursuant
to this Section 8(g)(1) shall be appropriately adjusted by means of a payment
from EVI to Parker or Parker to EVI, as the case may be, within 15 calendar
days after such adjustment.

         (2)     Any refund (whether by payment, credit, offset or otherwise)
of Taxes described in or covered by Section 8(e) (inclusive of any interest
thereon), regardless of whether such Taxes were paid before, on or after the
Closing Date, shall be the property of Parker and shall be retained by Parker
(or, if applicable, promptly paid or caused to be paid by EVI to Parker, within
15 calendar days after receipt, if any such refund (or interest thereon) is
received by EVI whether by payment, credit, offset or otherwise).  If there is
an adjustment to any such refund (or interest thereon), any payment or payments
theretofore made between the parties hereto with respect to such refund (or
interest thereon) pursuant to this Section 8(g)(2) shall be appropriately
adjusted by means of a payment from EVI to Parker or Parker to EVI, as the case
may be, within 15 calendar days after such adjustment.

         (h)     NATURE OF PAYMENTS.  Any payment from Parker to EVI pursuant
to this Section 8 shall be treated for Tax purposes as an increase in the
purchase price and any payment from EVI to Parker pursuant to this Section 8
shall be treated for Tax purposes as a reduction in the purchase price.

         9.      TERMINATION.

         (a)     TERMINATION OF AGREEMENT.  The Parties may terminate this
Agreement as provided below:

                 (1)      Parker and EVI may terminate this Agreement by mutual
         written consent at any time prior to the Closing;

                 (2)      EVI may terminate this Agreement at any time after
         January 31, 1997 if (A) Parker has not satisfied the condition
         precedent set forth in Section 6(a)(11), and (B) each





                                      -33-
<PAGE>   34
         other condition precedent set forth in Sections 6(a) (other than
         certificates or opinions to be delivered at Closing) shall have been
         satisfied.

                 (3)      Parker may terminate this Agreement upon a material
         breach of any representation, warranty, covenant or agreement on the
         part of EVI set forth in this Agreement, or if any representation or
         warranty of EVI shall have become untrue, in either case such that the
         conditions set forth in Sections 6(a)(1) or Section 6(a)(2) herein, as
         the case may be, would be incapable of being satisfied by February 28,
         1997; provided, that in any case, a willful breach shall be deemed to
         cause such conditions to be incapable of being satisfied for purposes
         of this Section 9(a)(3).

                 (4)      EVI may terminate this Agreement, upon a material
         breach of any representation, warranty, covenant or agreement on the
         part of Parker set forth in this Agreement, or if any representation
         or warranty of Parker shall have become untrue, in either case such
         that the conditions set forth in Section 6(b)(1) or Section 6(b)(2)
         herein, as the case may be, would be incapable of being satisfied by
         February 28, 1997; provided, that in any case, a willful breach shall
         be deemed to cause such conditions to be incapable of being satisfied
         for purposes of this Section 9(a)(4).

                 (5)      Parker or EVI may terminate this Agreement, if there
         shall be any order which is final and nonappealable preventing the
         consummation of the transactions contemplated hereby, except if the
         party relying on such order to terminate this Agreement has not
         complied with its obligations under Section 4(b) herein.

                 (6)      Parker or EVI may terminate this Agreement, if the
         Closing shall not have been consummated before February 28, 1997.

         (b)     EFFECT OF TERMINATION.  Except as provided in Section 9(c), if
any Party terminates this Agreement pursuant to Section 9(a), all rights and
obligations of the Parties hereunder shall terminate without any liability of
either Party to the other Party, except that nothing herein shall relieve any
party from liability for any breach of this Agreement and any termination shall
not be deemed to be a waiver of any applicable remedy for such breach.

         (c)     TERMINATION FOR FAILURE TO OBTAIN FINANCING.  If EVI
terminates this Agreement in accordance with its rights under Section 9(a)(2),
Parker will pay EVI an amount equal to $6,250,000 in cash, by wire transfer,
within five Business Days of such termination.

         10.     MISCELLANEOUS.

         (a)     PRESS RELEASES AND PUBLIC ANNOUNCEMENTS.  No Party shall issue
any press release or make any public announcement relating to the subject
matter of this Agreement prior to the Closing without the prior written
approval of Parker and EVI; provided, however, that either Party may make any
public disclosure it believes in good faith is required by applicable law or
any listing or trading agreement concerning its publicly traded securities (in
which case the disclosing Party will use all reasonable efforts to advise the
other Party prior to making the disclosure).

FOR IMMEDIATE RELEASE


EVI ANNOUNCES SALE OF MALLARD DRILLING FOR $338 MILLION


September 16, 1996, Houston, Texas - Energy Ventures, Inc. (NYSE-EVI) today
announced the signing of a definitive agreement to sell its Mallard Drilling
rig contracting division to Parker Drilling Company for total consideration of
$338 million, consisting of $313 million in cash and $25 million in convertible
preferred stock.

The transaction will close shortly after the completion of necessary financing
by Parker, which is expected to occur prior to December 31, 1996.

The sale of Mallard will allow EVI to focus on its core oilfield equipment
manufacturing businesses:  drill pipe, premium tubulars and artificial lift.
In the past six months EVI has completed four acquisitions in the premium
tubular and artificial lift business:  ENERPRO, TCA, PSI and Superior.  The
Company believes these segments offer further opportunities for significant
growth.  The Company's focus and its use of capital over the next year will be
to continue the growth of its oilfield equipment business.

EVI is an international oilfield service and equipment company with
manufacturing and rig operations in nine countries.  The Company manufactures
drill pipe and premium tubulars, production equipment and provides rig
contracting services.
