ITEM 5.  OTHER EVENTS.

         On February 21, 1997, Energy Ventures, Inc., a Delaware corporation
(the "Company"), entered into a Stock Purchase Agreement (the "Purchase
Agreement") with Seigo Arai and Kanematsu USA Inc., a New York corporation,
providing for the acquisition by the Company of TA Industries, Inc., a Delaware
corporation ("TA Industries"), in exchange for approximately $64 million cash
and assumed debt.

        TA Industries designs, manufactures and markets worldwide a complete
line of tubular couplings and accessories under the brand names Texas Arai and
Tube-Alloy.  The Company intends to integrate TA Industries with the Company's
drilling tools and premium tubulars division, thus creating an integrated
supplier of premium tubular products and services.  The Company expects to
benefit from the TA Industries acquisition through manufacturing synergies,
cost savings and reduced current inventory levels at TA Industries.

         The acquisition of TA Industries is subject to various conditions,
including the receipt of all required regulatory approvals and the expiration
of all waiting periods.  Although there can be no assurance that the Purchase
Agreement will close, the Company currently anticipates that the acquisition
will be consummated shortly after the receipt of such regulatory approvals.

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

         Statements made herein that are forward-looking in nature are intended
to be "forward-looking statements" within the meaning of Section 21E of the
Securities Exchange Act of 1934. Although the Company believes that the
expectations described herein are reasonable, the actual results could differ
materially from those currently anticipated. Factors that could cause results to
differ materially include, changes in industry conditions and demand for oil and
gas, changes in the market for premium tubular goods and couplings and delays in
the ability of the Company to fully integrate the operations of TA Industries
and achieve the strategic benefits described above.

         combined balance sheet (the "Closing Date Balance Sheet") of TxArai

         Statement cannot be resolved by the Stockholders and Purchaser within
         30 calendar days after the Objection Period, then, at the request of

         be submitted to Ernst & Young L.L.P. or such other independent
         accounting firm as may be approved by the Stockholders and Purchaser,
         which firm shall render its opinion as to such matters. Based on such
         opinion, such independent accounting firm will then send to the
         Stockholders and Purchaser its determination on the specified matters
         in dispute, which determination shall be final and binding on the

         3.2     Authority and Approval.  The execution and delivery of this
Agreement by Arai, the performance by Arai of all the terms and conditions
hereof to be performed by Arai and the consummation of the transactions
contemplated hereby by him have been duly authorized and approved by any
requisite corporate action on the part of the Company.  This Agreement
constitutes the legal, valid and binding obligation of Arai enforceable against
him in accordance with its terms, subject to applicable bankruptcy, insolvency
or other similar laws relating to or affecting the enforcement of creditors'
rights generally and to general principles of equity (regardless of whether
enforcement is considered in a proceeding in equity or at law).

         3.3     Capital Structure.  The authorized capital stock of the
Company consists of 100,000 shares of the Company Stock, of which 900 shares
are issued and outstanding.  There are no outstanding options, warrants,
convertible securities, calls, rights, commitments, preemptive rights,
agreements, arrangements or understandings of any character obligating the
Company (i) to issue, deliver or sell, or cause to be issued, delivered or
sold, additional shares of capital stock of the Company or any securities or
obligations convertible into or exchangeable for such shares or (ii) to grant,
extend or enter into any such option, warrant, convertible security, call,
right, commitment, preemptive right, agreement, arrangement or understanding
described in clause (i) above.

         of each Person in which the Company owns any equity or other similar
         ownership interests (each, a "Subsidiary", and collectively, the
         "Subsidiaries") and a description, including amount and percentage, of
         such interests.  The interests set forth on Schedule 3.4 are owned by
         the Company free and clear of all Encumbrances, including, voting
         trusts or stockholders agreements.

                 (b)      With respect to each Subsidiary set forth on Schedule
         3.4 in which the Company owns, directly or indirectly, a majority of
         the outstanding voting securities or any controlling equity interest:

                          (i)     Each such Subsidiary that is a corporation is
                 a corporation duly organized, validly existing and in good
                 standing under the laws of its jurisdiction of incorporation
                 and has the requisite corporate power and authority to carry
                 on its business as it is now being conducted, and to own,
                 operate and lease the Assets it now owns, operates or holds
                 under lease.  Each such Subsidiary that is not a corporation
                 is duly organized under the laws of its jurisdiction of
                 organization and has all requisite power and authority to

                 own, operate and lease the Assets that it now owns, operates
                 or holds under lease.

                          (ii)    Such Subsidiary is duly qualified to do
                 business and is in good standing in each jurisdiction in which
                 the conduct of its business or the ownership or leasing of its
                 Assets requires it to be so qualified, except





                                      -9-
<PAGE>   14



                 where the failure to be so qualified or in good standing would
                 not have a Material Adverse Effect.

                          (iii)   Arai has previously delivered to Purchaser

                 the date hereof.  The minute books of such Subsidiary
                 previously made available to Purchaser are complete in all
                 material respects and reflect all material action taken prior
                 to the date hereof by their board of directors or other

                 capacities as such.

                          (iv)    All the outstanding shares of capital stock
                 of each such Subsidiary that is a corporation have been duly
                 authorized and validly issued and are fully paid and
                 non-assessable and were not issued in violation of any
                 preemptive rights or other preferential rights of subscription
                 or purchase of any person.  All of the Company's direct or
                 indirect ownership interests in each such Subsidiary that is
                 not a corporation have been duly authorized and validly issued
                 or vested, were not issued in violation of any preemptive
                 rights or other preferential rights of subscription or
                 purchase of any Person, are fully paid and are non-assessable.

                 free and clear of all Encumbrances, including, voting trusts
                 or stockholder agreements.

                 convertible securities, calls, rights, commitments, preemptive
                 rights, agreements, arrangements or understandings of any
                 character obligating such Subsidiary (i) to issue, deliver or
                 sell, or cause to be issued, delivered or sold, additional
                 shares of capital stock or other equity interests of such
                 Subsidiary or any securities or obligations convertible into
                 or exchangeable for such shares or equity interests or (ii) to
                 grant, extend or enter into any such option, warrant,
                 convertible security, call, right, commitment, preemptive
                 right, agreement, arrangement or understanding described in
                 clause (i) of this Section 3.4.

         3.5     No Violation; Consents.  Except as set forth on Schedule 3.5,
this Agreement and the execution and delivery hereof by Arai do not, and the
fulfillment and compliance with the terms and conditions thereof and the
consummation of the transactions contemplated thereby will not, violate or

         Company and its Subsidiaries have good and indefeasible title to all
         of their respective personal property (including, without limitation,
         those items of personal property set forth on Schedule 3.10), free and
         clear of all Encumbrances, except for those Encumbrances set forth on
         Schedule 3.10.

                 (b)      There is set forth on Schedule 3.10 a list of each
         item of tangible personal property leased by the Company or any of its
         Subsidiaries that is material to the Company and its Subsidiaries
         taken as a whole.  The Company and its Subsidiaries have good title to
         all the leasehold estates pursuant to which all of the personal
         property leased by them is leased, free and clear of all Encumbrances,
         except for those Encumbrances set forth on Schedule 3.10.  Neither the
         Company nor any of its Subsidiaries has breached any provision of or
         is in default (and no event or circumstance exists that with notice,
         or the lapse of time or both, would constitute a default by the
         Company or any Subsidiary) under the terms of any lease or other
         agreement pursuant to which the personal property set forth on
         Schedule 3.10 is leased, except for a default or breach that would not
         have a Material Adverse Effect.  To the best knowledge of Arai, all of
         such leases or other agreements are in full force and effect.  There
         are no pending or, to the best knowledge of Arai, threatened disputes
         with

         respect to any lease or other agreement pursuant to which the personal
         property set forth on Schedule 3.10 is leased and, to the best
         knowledge of Arai, the lessor thereunder has not breached any
         provision of and is not in default (and no event or circumstance
         exists that with notice, or the lapse or time or both, would
         constitute a default by the lessor) under the terms of any such lease
         or other agreement.

                 (c)      There is set forth on Schedule 3.10 a description of
         all real property owned by the Company or any of its Subsidiaries.
         The Company and its Subsidiaries have good and indefeasible title to
         all of the real property set forth on Schedule 3.10 hereto, in fee
         simple absolute, free and clear of all Encumbrances, except for
         Encumbrances set forth on Schedule 3.10.  No parcel of the real
         property set forth on Schedule 3.10 is being condemned, expropriated
         or otherwise taken by any public authority, with or without payment of
         compensation therefor, and, to the best knowledge of Arai, no such
         condemnation, expropriation or taking has been proposed.

                 (d)      There is set forth on Schedule 3.10 a description of
         all real property leased by the Company and its Subsidiaries.  The
         Company and its Subsidiaries have good title to all the leasehold
         estates pursuant to which the real property set forth on Schedule 3.10
         is leased, free and clear of all Encumbrances set forth on such
         schedule.  Neither the Company nor any of its Subsidiaries has
         breached any provision of or is in default (and no event or
         circumstance exists that with notice, or the lapse of time or both,
         would constitute a default by the Company or any Subsidiary) under the
         terms of any lease or other agreement pursuant to which the real
         property set forth on Schedule 3.10 is leased.  To the best knowledge
         of Arai, all of such leases or other agreements are in full force and
         effect.  There are no pending or, to the best knowledge of Arai,
         threatened disputes with respect to any lease or other agreement
         pursuant to which the real property set forth on Schedule 3.10 is
         leased and, to the best knowledge of Arai, the lessor thereunder has
         not breached any provision of and is not in default (and no event or
         circumstance exists that with notice, or the lapse of time or both,
         would constitute a default by the lessor) under the terms of any such
         lease or other agreement.

                 (e)      Each of the Company and its Subsidiaries owns or
         possesses licenses or other rights to use all rights to all
         Proprietary Rights necessary for the conduct of the business of the
         Company and its Subsidiaries as currently conducted.  Set forth in
         Schedule 3.10 is a complete and accurate list of all patents,
         trademarks and licenses that the Company and its Subsidiaries own or
         possess or otherwise have rights to use and all patents, trademarks
         and licenses that the Company and its Subsidiaries own or possess or
         otherwise have rights to use.  No licenses, sublicenses, covenants or
         agreements have been granted or entered into by the Company or any
         Subsidiary in respect of the items listed in Schedule 3.10 except as
         noted thereon.  None of the Company or any of its Subsidiaries has
         received any notice of infringement, misappropriation or conflict from
         any other Person with respect to such Proprietary Rights and the
         conduct of the business of the Company and its Subsidiaries has not
         infringed,





                                      -15-

         misappropriated or otherwise conflicted with any Proprietary Rights of
         any such Person.  None of the Company or its Subsidiaries has given
         indemnification for patent, trademark, service mark or copyright
         infringements except to licensees or customers in the ordinary course
         of business.  All of the Proprietary Rights that are owned by the
         Company or its Subsidiaries are owned free and clear of all
         Encumbrances.  All Proprietary Rights that are licensed by the Company
         or any of its Subsidiaries from third parties are licensed pursuant to
         valid and existing license agreements and such interests are not
         subject to any Encumbrances other than those under the applicable
         license agreements.  The consummation of the transactions contemplated
         by this Agreement will not result in the loss of any Proprietary
         Rights and will not conflict with, constitute a breach, violation or
         termination of, any agreement or understanding, whether written or
         otherwise, relating to any Proprietary Rights necessary for the
         conduct of the business by the Company or its Subsidiaries as
         currently conducted.

         3.11    No Brokers.  None of Arai, the Company or any of its
Subsidiaries has employed or retained any investment banker, broker, agent,
finder or any other party, or incurred any obligation for broker's fees,
finder's fees or commissions, with respect to the sale of the Company Stock or
with respect to the transactions contemplated by this Agreement, or otherwise
dealt with anyone purporting to act in the capacity of a finder or broker with
respect thereto whereby the Company, any of its Subsidiaries or Purchaser may
be obligated to pay such a fee or commission.  Arai agrees to indemnify and
hold Purchaser harmless from and against any and all claims, liabilities or
obligations with respect to any fees, commissions or expenses asserted by any
Person on the basis of any act, statement, agreement or commitment alleged to
have been made by any of the Company or its Subsidiaries or by Arai or any
Affiliate thereof with respect to any such fee, expense or commission.

         3.12    Environmental Matters.  Except as set forth in Schedule 3.12:

                 (a)      Each of the Company and its Subsidiaries has, to the
         best knowledge of Arai, at all times operated in compliance with all
         applicable limitations, restrictions, conditions, standards,
         prohibitions, requirements and obligations of Environmental Laws and
         related orders of any court or other Governmental Entity, except where
         the failure to so operate in compliance would not have a Material
         Adverse Effect.

                 (b)      Except as listed on Schedule 3.12, there are no
         existing, pending or, to the best knowledge of Arai, threatened
         actions, suits, claims, investigations, inquiries or proceedings by or
         before any court or any other Governmental Entity directed against the
         Company, any of its Subsidiaries or any of their respective assets
         which pertain or relate to (i) any remedial obligations under any
         applicable Environmental Law, (ii) violations of any Environmental
         Law, (iii) personal injury or property damage claims relating to the
         release of Waste Materials or (iv) response, removal or remedial costs
         under CERCLA or any similar state law.

         authorizations required to be obtained or filed by the Company or any
         of its Subsidiaries under all applicable Environmental Laws in
         connection with its current and, to the best knowledge of Arai,
         previous operation or use of the assets, any other assets or
         properties currently or, to the best knowledge of Arai, previously
         leased or owned by the Company or any of its Subsidiaries or the
         current and previous conduct of its business have been duly obtained
         or filed and are in full force and effect, except where the failure to
         do so would not have a Material Adverse Effect.

                 (d)      Neither the Company nor any of its Subsidiaries has
         received notice that any permit, license or similar authorization is
         to be revoked or suspended by any Governmental Entity.

                 (e)      Neither the Company nor any of its Subsidiaries owns

         to the best knowledge of Arai, previously leased or owned by the
         Company or any of its Subsidiaries is part of a Superfund site under
         CERCLA or any similar ranking or listing under any similar state law.

                 (g)      To the best knowledge of Arai, all Waste Materials
         generated by the Company or any of its Subsidiaries that are stored or
         that require treatment or disposal have been transported, stored,
         treated and disposed of by carriers, and by storage, treatment and
         disposal facilities authorized and maintaining valid permits under all
         applicable Environmental Laws, except for such matters that would not
         have a Material Adverse Effect.

                 (h)      To the best knowledge of Arai, no person has disposed
         or released any Waste Materials on or under any asset or property
         currently or, to the best knowledge of the Stockholders, previously
         leased or owned by the Company or any of its Subsidiaries and neither
         the Company nor any of its Subsidiaries has disposed or released Waste
         Materials on or under the assets or properties currently or, to the
         best knowledge of Arai, previously leased or owned by the Company or
         any of its Subsidiaries, except in compliance with all applicable
         Environmental Laws, except for such matters that would not have a
         Material Adverse Effect.

                 (i)      To the best knowledge of Arai, no facts or
         circumstances exist that could reasonably be expected to result in any
         liability to any person with respect to the current or past business
         and operations of the Company, any of its Subsidiaries, the assets or
         properties currently or previously leased or owned by the Company or

         3.13    Financial Statements.

                 (a)      True and correct copies of (i) the audited
         consolidated balance sheet of Texas Arai, Inc., a Delaware corporation
         and wholly owned Subsidiary ("TxArai"), as of September 30, 1996, and
         (ii) the audited consolidated balance sheet of Tube-Alloy Capital
         Corporation, a Texas corporation and wholly owned Subsidiary
         ("Tube-Alloy") at December 31, 1995 (collectively, the "Financial
         Statements"), have been previously delivered to Purchaser.  The
         Financial Statements fairly present the financial position of TxArai
         and Tube-Alloy as at the dates thereof and the cash flows and results
         of operations for the periods covered thereby, and have been prepared
         in accordance with GAAP.

                 (b)      True and correct copies of the unaudited consolidated
         balance sheet of Tube-Alloy as of September 30, 1996, and the
         statement of income for the nine months ended September 30, 1996 have
         been previously delivered to Purchaser (the "Interim Financial
         Statements").  The Interim Financial Statements fairly present the
         financial position of Tube-Alloy and its Subsidiaries at September 30,
         1996 and results of operations for the nine months ended September 30,
         1996, and are prepared in a manner consistent with the Financial
         Statements and in accordance with GAAP.

                 (c)      True and correct combined consolidated financial
         statements for TxArai and Tube-Alloy as of September 30, 1996, and for
         the nine months ended September 30, 1996, together with the combining
         and consolidating statements relating thereto (the "September 30
         Combined Financials") have previously been provided to Purchaser.  The
         September 30 Combined Financials fairly present the combined financial
         position of TxArai and Tube-Alloy as of September 30, 1996, and the
         results of operations for the nine months then ended in a manner
         consistent with the Financial Statements and GAAP.

                 (d)      Except as set forth or reserved for on the Interim
         Financial Statements and the September 30 Combined Financials, or on
         Schedule 3.13, neither the Company nor any of its Subsidiaries has any
         liabilities of any nature, whether accrued, absolute, contingent,
         unliquidated, civil, criminal or otherwise, and whether due or to
         become due, other than those liabilities that (i) are fully reflected
         or reserved against in the September 30 Combined Financials, (ii)
         incurred in the ordinary course of business or (iii) are expressly
         disclosed in any other Schedule hereto.

         3.14    Absence of Certain Transactions.  Except as set forth in
Schedule 3.14, since September 30, 1996, the Company has not engaged in any of
the transactions described in subsections (c), (d), (e), (g), (h), (m) and (n)
of Section 6.1.  Since September 30, 1996, there has not occurred any event or
matter that would have a Material Adverse Effect.

         other than the Company or any Subsidiaries or (v) take any preliminary
         action with respect to the foregoing.

         6.2     Governmental Approvals; Consents.

                 (a)      Until the Closing, Arai shall, and shall cause the
         Company to, use its reasonable best efforts, and shall cooperate with
         Purchaser, to obtain all permits, approvals, filings and consents
         necessary or required to be obtained or made, and all waiting periods
         required to expire, for the consummation of the transactions
         contemplated by this Agreement under any applicable federal law or any
         state having jurisdiction over the transactions contemplated hereby
         (all such permits, approvals, filings and consents and the lapse of
         all such waiting periods being referred to as the "Requisite
         Regulatory Approvals"); and

                 (b)      Until the Closing, Arai shall, and shall cause the
         Company to, use its reasonable best efforts to obtain all consents,
         approvals, clearances, waivers, orders or authorizations of any Person
         necessary to be obtained by the Company and its Subsidiaries or the
         Stockholders for the consummation of the transactions contemplated by
         this Agreement.

         6.3     Litigation and Claims.  Until the Closing, Arai shall promptly
inform Purchaser in writing of any litigation, or of any claim or controversy
or contingent liability that might reasonably be expected to become the subject
of litigation, against the Company or any of its Subsidiaries or affecting any
of their respective Assets.

         6.4     Notice of Changes.  Until the Closing, Arai shall promptly
inform Purchaser in writing if any change shall have occurred or shall have
been threatened (or any development shall have occurred or shall have been
threatened involving a prospective change) in the financial condition, results
of operations, business or Assets of the Company or any of its Subsidiaries
that is or may reasonably be expected to have a Material Adverse Effect.  Until
the Closing, Arai shall promptly inform Purchaser in writing if any
representation or warranty made by Arai in this Agreement shall cease to be
accurate or any breach of any covenant or other agreement required by this
Agreement to be performed or complied with by Arai.

         6.5     Access to Information.  Prior to the Closing, Arai shall cause
the Company to allow Purchaser to make such investigation of the business and
properties of the Company and its Subsidiaries as Purchaser may desire and,
upon reasonable notice, cause the Company to give to Purchaser and its counsel,
accountants and other representatives reasonable access, during normal business
hours throughout the period prior to the Closing, to the property, books,
commitments, agreements, records, files and personnel of the Company and its
Subsidiaries, and shall cause the Company to furnish to Purchaser during that
period all copies of documents and information concerning the Company as
Purchaser may reasonably request, subject to applicable law.  All information
furnished to Purchaser and its representatives under this Section 6.5 shall be
kept confidential by such persons in accordance with the Confidentiality
Agreement dated December 9, 1996, between the Purchaser and Arai, as amended
from time to time (the "Confidentiality Agreement").

         6.6     Covenant Not to Compete With the Business.  As an inducement
to the Purchaser to acquire the Stock, Arai agrees that, except as otherwise
permitted herein, effective as of the Closing Date and for a period of three
years thereafter, he and his Affiliates shall not, without the consent of
Purchaser, directly engage in the manufacture of (i) couplings and accessories
used for oilfield tubular goods or (ii) products of a type currently
manufactured by the Company or any of its Subsidiaries.  Aria acknowledges that
a remedy at law for any breach or attempted breach of this Section 6.6 will be
inadequate and further agrees that any breach of this Section 6.6 will result
in irreparable harm to Purchaser and Purchaser shall, in addition to any other
remedy that may be available to it, be entitled to specific performance and
injunctive and other equitable relief in case of any such breach or attempted
breach.  Arai acknowledges that this covenant not to compete is being provided
as an inducement to the Purchaser to acquire the Company Stock and that this
Section 6.6 contains reasonable limitations as to time, geographical area and
scope of activity to be restrained that do not impose a greater restraint than
is necessary to protect the goodwill or other business interest of Purchaser.
Whenever possible, each provision of this Section 6.6 shall be interpreted in
such a manner as to be effective and valid under applicable law, but if any
provision of this Section 6.6 shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remaining provisions of
this Section 6.6.  If any provision of this Section 6.6 shall, for any reason,
be judged by any court of competent jurisdiction to be invalid or
unenforceable, such judgment shall not affect, impair or invalidate the
remainder of this Section 6.6 but shall be confined in its operation to the
provision of this Section 6.6 directly involved in the controversy in which
such judgment shall have been rendered.  In the event that the provisions of
this Section 6.6 should ever be deemed to exceed the time or geographic
limitations permitted by applicable laws, then such provision shall be reformed
to the maximum time or geographic limitations permitted by applicable law.
Notwithstanding anything to the contrary contained in this Section 6.6,
Purchaser acknowledges that Arai owns a minority interest in Arai Iron Works
Co. Ltd. ("AIW") which may compete with Company and its Subsidiaries and that
Arai shall be able to consult with and provide guidance to the management of
AIW but shall not serve as an employee, officer or director of AIW.

         6.7     Right of First Refusal.

                 (a)      Purchaser agrees that if, at any time during a period
         of two years following the Closing Date, it shall elect to sell
         (whether by sale of assets or stock) the United States business that
         was conducted by the Company and its Subsidiaries as of the Closing
         Date (the "Company Business") to any Person that is not an Affiliate
         of the Purchaser (a "Proposed Disposition"), Purchaser shall (or shall
         cause any Affiliate of Purchaser to which the Company Business may
         have subsequently been transferred or conveyed, whether by asset
         transfer, stock transfer, merger or otherwise, to) offer to Arai the
         right to acquire the Facility that is proposed to be sold on the same
         terms and conditions under which Purchaser or its Affiliate proposes
         to dispose of the Company Business.

<PAGE>   29


                 (b)      In the event of any Proposed Disposition, Purchaser
         shall provide to Arai, at least 45 days prior to the Proposed
         Disposition, (i) the general terms and conditions of the Proposed
         Disposition (provided, however, Purchaser need not provide to Arai the
         name of the proposed purchaser) and (ii) the documentation required to
         be executed by Arai to purchase the Company Business that is subject
         to the Proposed Disposition, which documentation shall be the same as
         the documentation for the Proposed Disposition other than information
         relating to the parties and conditions relating to Arai's rights under
         this Agreement (the "Sale Documentation").

                 (c)      If Arai elects to acquire the Company Business that
         is subject to the Proposed Disposition, Arai shall (i) notify the
         Purchaser in writing of such election by executing and delivering to
         Purchaser the Sale Documentation (together with any funds to be
         provided therewith) no later than 15 days after receipt of such notice
         and (ii) subject to receipt of any necessary regulatory approvals on
         the part of the Purchaser or any of its Affiliates, close the
         transaction within five days thereafter or on the date that such
         approval shall have been obtained.

                 (d)      The foregoing right of first refusal granted to Arai
         shall not apply (i) to any merger, consolidation, share exchange,
         combination, sale of stock or change in control of Energy Ventures,
         Inc., or any successor thereto, (ii) any transfer, sale, conveyance,
         merger, consolidation, share exchange or other business combination
         involving all or substantially all of Purchaser's and its
         Subsidiaries' United States tubular manufacturing operations, (iii)
         any transfer, sale, merger or conveyance of the stock of Grant
         Prideco, Inc.  (or any successor thereto), (iv) any merger,
         consolidation or transfer of stock or assets to any Affiliate of the
         Purchaser or any of the Purchaser's or its Affiliates' current or
         future Subsidiaries or (v) any manufacturing or operating changes
         effected by Purchaser or its Affiliates after the Closing with respect
         to the Company or any of its Subsidiaries or the Company Business as
         long as the Company or the Company Business continues to be owned or
         operated by the Company or any of its Affiliates.

                 (e)      The provisions of this Section 6.7 shall be null,
         void and of no further force and effect in the event that Arai
         voluntarily elects to terminate his employment with Purchaser or any
         of its Affiliates prior to the expiration of the term ending two years
         following the Closing Date.

                 (f)      The rights provided under this Section 6.7 shall be
         considered personal rights of Arai and may not, directly or
         indirectly, be transferred, assigned or otherwise conveyed by Arai by
         contract, operation of law or otherwise to any third party and any
         breach or attempted breach by Arai shall terminate any further
         obligations of Purchaser and its Affiliates under this Section 6.7.

         6.8     Employee Matters.

                 (a)      In determining eligibility for and entitlement to
         vacation and other normal benefits (excluding stock-based plans and
         incentive programs) based on length of service by employees of the
         Company and its Subsidiaries under the Purchaser's normal policies,
         Purchaser agrees that service with the Company and its Subsidiaries

         with the Purchaser and its Affiliates.

                 (b)      Purchaser shall make available to the employees of

         subject to a maximum payment under that plan of $2,600,000.

         and controlling Persons and their respective successors and assigns
         harmless from and against and in respect of Damages actually suffered,
         incurred or realized by such party (collectively, "Purchaser Losses"),
         arising out of or resulting from or relating to any





                                      -29-
<PAGE>   34


         misrepresentation, breach of warranty or breach of any covenant or
         agreement made or undertaken by Arai in this Agreement or any
         misrepresentation in or omission from any other agreement,
         certificate, exhibit or writing delivered to the Purchaser pursuant to
         this Agreement by Arai, including the Schedules hereto.

                 (b)      Kanematsu agrees to indemnify, defend and hold
         Purchaser and each of its officers, directors, employees, agents,
         stockholders and controlling Persons and their respective successors
         and assigns harmless from and against and in respect of Purchaser
         Losses arising out of or resulting from or relating to any
         misrepresentation or breach of warranty made by Kanematsu in this
         Agreement.

                 (c)      Notwithstanding the foregoing, Arai shall not be
         liable under Section 10.1(a) in respect of a misrepresentation or
         breach of warranty unless and until the aggregate amount of any
         Purchaser Losses for which the Purchaser is entitled to
         indemnification from Arai exceeds $500,000; provided, however, (i)
         such limitation shall not apply if such Purchaser Losses arise from a
         breach of any of the representations set forth in Sections 3.3,
         3.4(b)(iv) and (v), 3.11, 4.1, 4.2 and 4.5 and (ii) except for
         liability for Purchaser Losses that arise from a breach of any of the
         representations and warranties set forth in Sections 3.3, 3.4(b)(iv)
         and (v), 3.10, 4.1, 4.2 and 4.5, which shall not be limited, the
         liability of Arai for his representations and warranties shall not
         exceed $1,500,000 in the aggregate.

         10.2    Indemnification by Purchaser.  Except as otherwise limited by
this Article 10 and Article 11 hereof, Purchaser agrees to indemnify, defend
and hold the Stockholders and each of their officers, directors, employees,
agents, stockholders and controlling Persons and its successors and assigns
harmless from and against and in respect of Damages actually suffered, incurred
or realized by such party (collectively, "Stockholder Losses"), arising out of
or resulting from any misrepresentation, breach of warranty or breach of any
covenant or agreement made or undertaken by Purchaser in this Agreement or any
misrepresentation in or omission from any other agreement, certificate, exhibit
or writing delivered to Stockholders by Purchaser pursuant to this Agreement.

         10.3    Notice and Opportunity to Defend.

                 (a)      If a party seeking indemnification (the "Indemnitee")
         becomes aware of any matter that it believes may give rise to an
         indemnifiable claim, or asserts any claim that it believes may be
         indemnifiable pursuant to Section 10.1 or 10.2 hereof, the Indemnitee
         shall give the party obligated to provide indemnification (the
         "Indemnifying Party") prompt written notice of such matter or claim,
         stating with particularity the nature of such matter or the
         aforementioned claim and the amount thereof.  Failure to provide such
         notice shall not affect the right of the Indemnitee to indemnification
         except to the extent such failure shall have resulted in liability to
         the Indemnifying Party that could have been actually avoided had such
         notice been provided within such required time period.

<PAGE>   35



                 (b)      If the matter that the Indemnitee believes gives rise
         to an indemnifiable claim does not involve a third party claim against
         an Indemnitee, the Indemnifying Party shall have 30 days from the date
         on which it received notice of such claim pursuant to this Section
         10.3 to respond to such notice.  If such Indemnifying Party accepts
         responsibility or does not respond within such 30-day period,
         Indemnifying Party shall promptly pay to the Indemnitee the full
         amount of such claim.  If the Indemnifying Party rejects any liability
         with respect to such claim, it shall give notice of such objection to
         the Indemnitee within such 30- day period and the parties shall seek
         to resolve such claim by agreement.  If such claim is unable to be
         resolved by agreement within 60 days following the expiration of such
         30-day period mentioned above, the parties shall be entitled to
         pursue, without prejudice to any of its rights hereunder, such
         remedies as may be available to such party under applicable law.

                 (c)      In the event any action, suit, proceeding or
         investigation is brought against the Indemnitee by a third party which
         the Indemnitee believes may give rise to an indemnifiable claim
         pursuant to Section 10.1 or 10.2 hereof, the Indemnitee shall give the
         Indemnifying Party prompt written notice of the commencement of such
         action, suit, proceeding or investigation as provided in subsection
         (a) of this Section 10.3.  Such Indemnifying Party shall have a period
         of 30 days after receipt of such notice within which to respond to
         such notice. If such Indemnifying Party accepts responsibility, such
         Indemnifying Party shall be obligated to compromise or defend such
         matter, at its own expense and by counsel chosen by the Indemnifying
         Party reasonably acceptable to the Indemnitee.  The Indemnitee shall
         have the right to participate at its own expense in the defense of
         such asserted liability.  If such Indemnifying Party does not respond
         within such 30-day period or rejects responsibility for such matter in
         whole or in part, the Indemnitee shall be free to pursue, without
         prejudice to any of its rights hereunder, such remedies as may be
         available to such party under applicable law.  The Indemnitee shall
         cooperate fully with the Indemnifying Party and its counsel in the
         defense against any such asserted liability.  Any compromise of such
         asserted liability by the Indemnifying Party shall require the prior
         written consent of the Indemnitee, which shall not be unreasonably
         withheld.  If, however, the Indemnitee refuses its consent to a bona
         fide offer of settlement which involves solely the payment of cash
         which the Indemnifying Party wishes to accept, the Indemnitee may
         continue to pursue such matter, free of any participation by the
         Indemnifying Party, at the sole expense of the Indemnitee.  In such
         event, the obligation of the Indemnifying Party to the Indemnitee
         shall be equal to the lesser of (i) the amount of the offer of
         settlement which the Indemnitee refused to accept plus the costs and
         expenses of the Indemnitee prior to the date the Indemnifying Party
         notifies the Indemnitee of the offer of settlement, and (ii) the
         actual out-of-pocket amount the Indemnitee is obligated to pay as a
         result of such party's continuing to pursue such matter.  An
         Indemnifying Party shall be entitled to recover from the Indemnitee
         any additional expenses incurred by such Indemnifying Party as a
         result of the decision of the Indemnitee to pursue such matter.

                NATURE OF STATEMENTS AND SURVIVAL OF COVENANTS,
                   REPRESENTATIONS, WARRANTIES AND AGREEMENTS

         All statements of fact contained in any written statement (including
financial statements), certificate, instrument or document delivered by or on
behalf of a Stockholder pursuant to this Agreement shall be deemed
representations and warranties of that Stockholder.  The several
representations and warranties of the parties to this Agreement shall survive
the Closing Date and shall remain in full force and effect for a period of two
years following the Closing Date (except that the representations and
warranties set forth in Sections 3.3, 3.4, 3.10, 3.11, 4.1, 4.2 and 4.5 shall
survive the Closing Date without limitation) (the period during which the
representations and warranties shall survive being referred to herein with
respect to such representations and warranties as the "Survival Period"), and
shall be effective with respect to any inaccuracy therein or breach thereof
(and a claim for indemnification under Article 10 hereof may be made thereon)
if a written notice asserting the claim shall have been duly given in
accordance with Article 10 hereof within the Survival Period with respect to
such matter.  All covenants and agreements contained herein shall survive
without limitation; provided, however, that such survival shall not operate to
expand the indemnification obligations set forth in Article 10.  Any claim for
indemnification made during the Survival Period shall be valid and the
representations and warranties relating thereto shall remain in effect for
purposes of such indemnification notwithstanding such claim may not be resolved
within the Survival Period.  All representations, warranties and covenants and
agreements made by the parties shall not be affected by any investigation
heretofore or hereafter made by and on behalf of any of them and shall not be
deemed merged into any instruments or agreements delivered in connection with
this Agreement or otherwise in connection with the transactions contemplated
hereby.

                                 MISCELLANEOUS

         12.1    Entire Agreement.  This Agreement and the other agreements
contemplated hereby constitute the sole understanding of the parties with
respect to the matters provided for herein and supersedes any previous
agreements and understandings between the parties with respect to the subject
matter hereof.  No amendment, modification or alteration of the terms or
provisions of this Agreement shall be binding unless the same shall be in
writing and duly executed by Purchaser and the affected Stockholders.

         12.2    Successors and Assigns.  The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the parties hereto
and their respective successors and assigns.  Prior to the Closing Date, this
Agreement may not be assigned by any party without the prior written consent of
the other party hereto, except that the Purchaser may, at its election, assign
its rights under this Agreement to any direct or indirect wholly owned
subsidiary.  Notwithstanding the foregoing, no assignment of





                                      -33-
<PAGE>   38



this Agreement or any of the rights or obligations hereof by Purchaser or by
the Stockholders, as the case may be, shall relieve Purchaser or the
Stockholders of its obligations under this Agreement and, upon any such
assignment occurring prior to the Closing, the representations, warranties,
covenants and agreements contained in this Agreement shall be deemed to have
been made by Purchaser's assignee or by the Stockholders's assignee as well as
by Purchaser or by the Stockholders, as the case may be.

         12.3    Arbitration.

                 (a)      In the event there shall exist any dispute or
         controversy between the Purchaser and the Stockholders with respect to
         this Agreement or any matter relating hereto or the transactions
         contemplated hereby, the parties hereto agree to seek to resolve such
         dispute or controversy by mutual agreement.  If such dispute or
         controversy is unable to be resolved by agreement within 60 days
         following notice by Purchaser or the Stockholders of the nature of
         such dispute or controversy setting forth in reasonable detail the
         circumstances and basis of such dispute or controversy, either
         Purchaser or the Stockholders, as the case may be, may require that
         such dispute or controversy be resolved by binding arbitration
         pursuant to the provisions of this Section 12.3.  If a party elects to
         submit such matter to arbitration, such party shall provide notice to
         the other party of its election to do so, which notice shall name one
         arbitrator.  Within 10 days after the receipt of such notice, the
         other party shall name a second arbitrator.  The two arbitrators so
         appointed shall name a third arbitrator, or failing to do so, a third
         arbitrator shall be appointed pursuant to the Commercial Arbitration
         Rules of the American Arbitration Association.  Each arbitrator
         selected to act hereunder shall be qualified by education and
         experience to pass on the particular question in dispute.  The
         arbitrators shall resolve all disputes in controversy in accordance
         with the applicable substantive law.  All statutes of limitations that
         would otherwise be applicable shall apply to any arbitration
         proceeding.

                 (b)      The arbitrators appointed pursuant to this Section
         12.3 shall promptly hear and determine (after due notice and hearing
         and giving the parties reasonable opportunity to be heard) the
         questions submitted, and shall render their decision within 60 days
         after appointment of the third arbitrator or as soon as practical
         thereafter.  If within such period a decision is not rendered by the
         board or a majority thereof, new arbitrators may be named and shall
         act hereunder at the election of either party in like manner as if
         none had previously been named.  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.

                 (c)      All expenses of arbitration, including reasonable
         compensation to the arbitrators and expenses of parties' counsel,
         witnesses and employees shall be borne as determined by the
         arbitrators.

                 (d)      Nothing contained herein shall prohibit any party
         from seeking injunctive or other equitable relief pending any decision
         in arbitration or from enforcing any order or decision by the
         arbitrators in any court or other appropriate forum.   For purposes of
         injunctive relief, orders in aid of arbitration and entry of the
         arbitrator's award:

                          (i)     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 Indemnitee may be brought with respect to any
                 claim for indemnification by an Indemnitee;

                          (ii)    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 Indemnitee may be brought with respect to any
                 claim for indemnification by an Indemnitee, 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; and

                          (iii)   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, service of any and all legal
                 process, summons, notices and documents which may be served in
                 any suit, action or proceeding arising out of or relating to
                 this Agreement or any of the other agreements contemplated
                 hereby.

         12.4    Expenses.  Whether or not the transactions contemplated by
this Agreement are consummated, other than as expressly provided for herein,
each of the parties hereto shall pay the fees and expenses of its respective
counsel, accountants and other experts, and all other expenses incurred by such
party incident to the negotiation, preparation and execution of this Agreement
and consummation of the transactions contemplated hereby.

         12.5    Effect of Due Diligence.  No investigation by Purchaser, its
Affiliates, agents or advisers into the business, operations, Assets and
condition of the Company or any of its Subsidiaries shall diminish in any way
the effect of any representations or warranties made by the Stockholders in
this Agreement or shall relieve the Stockholders of any of their respective
obligations under this Agreement.

applicable laws, to use all reasonable best efforts promptly to take or cause
to be taken all action and to promptly do or cause to be done all things
necessary, proper or advisable under applicable laws and regulations to

Each party shall cooperate with the other in good faith to help the other
satisfy its obligations hereunder.  If at any time after the Closing Date any

is invalid, illegal or incapable of being enforced by any rule of law, or
public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic and legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party.  Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner to the end that transactions contemplated hereby are fulfilled to the

EVI TO ACQUIRE TA INDUSTRIES FOR $64 MILLION

February 24, 1997, Houston, Texas - Energy Ventures, Inc. (NYSE-EVI) today
announced the signing of a definitive agreement to purchase the stock of TA
Industries, Inc. for total consideration of approximately $64 million in cash
and assumed debt.

TA Industries had total revenues for the year ended December 31, 1996 of
approximately $80 million.  TA Industries designs, manufactures and markets
worldwide a complete line of tubular couplings and accessories such as pup
joints, crossovers, flow couplings, blast joints and engineered downhole
equipment.  The product lines are marketed under the brand names Texas Arai and
Tube-Alloy and are believed to be the industry's market leader in their
segments.

TA Industries product lines are an integral component of oilfield tubing,
casing and liner strings when a well is first completed and throughout the
producing life of the well.  They are particularly critical in wells requiring
tubulars with premium specifications.  These products for use in premium
tubular applications are typically custom designed with proprietary technology
and very high manufacturing tolerances.  The term premium, as a qualifier to
tubulars, refers primarily to the complex engineered connections that tie
together the various components of the tubing, casing and liner strings.  It
additionally implies a combination of chemistry grade and fabrication methods.
Premium tubulars are used in difficult downhole environment brought about by
depth, temperature, pressure, corrosion and directional angle.  Such wells are
generally found offshore and more particularly in deep waters where almost all
wells require premium tubulars.  The Company believes that wells requiring
premium tubulars are enjoying a multi year secular growth trend.

Upon completion of the transaction, Texas Arai and Tube-Alloy will become
divisions of Grant Prideco, EVI's drilling tools and premium tubulars segment.
Texas Arai and Tube-Alloy will join the Company's growing business in premium
tubulars with its Atlas Bradford (premium connection), TCA (premium casing &
liner) and Grant Prideco (premium tubing) divisions.  The combination will
create the only integrated supplier of premium tubular products and services in
the world.  This coordinated approach to tubular applications will be of
particular importance internationally, where time and logistical considerations
are an integral part of every purchase decision.  The acquisition is also
expected to provide significant manufacturing synergies with TCA, the premium
casing division acquired by EVI in August 1996.  Through these synergies, the
Company expects to realize cost savings between $1.5 and $2.5 million per year,
as well as being able to reduce current inventory levels at TA Industries by up
to $8 million.

The acquisition of TA Industries is subject to various conditions, including
the receipt of all required regulatory approvals and expiration of all waiting
periods.  The acquisition is expected to close as soon as possible after the
receipt of the necessary approvals.

EVI is an international manufacturer of engineered oilfield products.  The
Company manufactures drilling tools, premium tubulars and production equipment.
