COMBINATION AGREEMENT THIS AGREEMENT is entered into on this day of 10 October 2002 (the "Agreement"), by and between NATIONAL-OILWELL, INC ("NOI"), a corporation organized and existing under the laws of the United States of America; and HYDRALIFT ASA ("Hydralift"), a corporation organized and existing under the laws of Norway. NOI and Hydralift are hereinafter jointly referred to as "Parties" and each of them a "Party". RECITALS: A. NOI is a worldwide leader in the design, manufacture and sale of comprehensive systems and components used in oil and gas drilling and production. B. Hydralift is a leading supplier of hydraulic and electric systems and equipment for selected niches in the offshore and marine markets. C. The Boards of Directors of each of NOI and Hydralift have determined that it is in the best interests of their respective companies and shareholders to combine the businesses of NOI and Hydralift through the acquisition by NOI of the shares of Hydralift in a public tender offer to be effected as set forth in this Agreement.

2 D. Following the combination, NOI desires to further develop and continue Hydralift role and position within the offshore drilling equipment, offshore production equipment and floating production markets and to conduct those activities out of Kristiansand. E. The Parties intend, upon the terms and subject to the conditions of this Agreement, that NOI or a wholly owned subsidiary of NOI, shall acquire, through a voluntary public tender offer (the "Tender Offer") and, if necessary, through a subsequent mandatory tender offer and compulsory acquisition proceedings in accordance with applicable Norwegian law, all of the issued and outstanding shares of Hydralift (the "Hydralift Shares"), as more fully described below. F. As a result of the transactions described in Recital E, Hydralift will become a subsidiary of NOI and the present holders of Hydralift Shares will as consideration for Hydralift Shares receive cash, as more fully described below. G. The Boards of Directors of NOI and Hydralift have each approved this Agreement. The Board of Directors of Hydralift has decided to recommend to the shareholders of Hydralift that they tender their Hydralift Shares in accordance with the terms of the Tender Offer. NOW THEREFORE, the Parties hereby agree as follows: 1 THE TENDER OFFER 1.1 THE TENDER OFFER NOI shall commence the Tender Offer on or about 8 November, 2002. Pursuant to the Tender Offer, NOI shall offer to pay a consideration of NOK 55 for each Hydralift Share. The main Terms and Conditions for the Tender Offer are set out in ANNEX 1.

3 A tentative time schedule for the Tender Offer is set forth in ANNEX 2. The Parties agree that they have a common goal and interest in commencing and completing the Tender Offer as soon as practical and shall use their best efforts in this regard. The initial expiration date of the Tender Offer shall be a date (such date, as it may be extended from time to time as hereinafter provided, being referred to herein as the "Expiration Date") which is not later than three (3) weeks after the date on which the Tender Offer commences. The Expiration Date may be extended by NOI from time to time until such time as all of the Transaction Conditions have been satisfied. Subject only to the conditions set forth above, NOI shall acquire and pay for all Hydralift Shares validly tendered and not withdrawn pursuant to the Terms and Conditions at the earliest practicable time following the Expiration Date (such date of acceptance being referred to herein as the "Closing Date"). 1.2 CONDITIONS The obligation of NOI to acquire and to pay for Hydralift Shares tendered pursuant to the Tender Offer shall be subject only to this Agreement not having been terminated and the satisfaction or waiver by NOI of the conditions listed in Annex 1 (the "Transaction Conditions"). 1.3 HYDRALIFT BOARD SUPPORT The Board of Directors of Hydralift has decided to support the Tender Offer and will recommend to all the shareholders of Hydralift that they accept the Tender Offer and tender their shares pursuant to the Terms and Conditions and to issue a statement in the form set out in ANNEX 3, provided, however, that such recommendation may at any time prior to the Closing Date be cancelled, modified or amended if and when the Board of Directors of Hydralift, having received a competing offer for the Hydralift Shares and after having obtained advice from its legal counsel, determines in good faith that a failure to so cancel, modify or amend its recommendation would under applicable laws constitute a breach of its fiduciary duties towards the shareholders of Hydralift.

4 1.4 MANDATORY TENDER OFFER AND COMPULSORY ACQUISITION As soon as practicable after the Closing Date, assuming that the Transaction Conditions shall have been either satisfied or waived, NOI shall, subject to the applicable rules, regulations and procedures, make a mandatory tender offer as regulated by Norwegian securities market legislation and take the necessary action under Norwegian law to acquire all the remaining issued and outstanding Hydralift Shares and to de-list the Hydralift Shares from the Oslo Stock Exchange ("OSE"). 1.5 MANAGEMENT COMMITMENT The Chairman of the Board of Hydralift, Mr. Bjarne Skeie, and the Managing Director of Hydralift, Mr. Birger Skeie, have expressed their support of the combination of NOI and Hydralift and confirmed that they will not terminate their employment with Hydralift as a consequence of the transactions contemplated in this Agreement in the form set out in ANNEX 4. 1.6 NON-COMPETE OBLIGATION The Chairman of the Board of Hydralift, Mr. Bjarne Skeie, have confirmed that he will not compete with the business of NOI or Hydralift, or any of their subsidiaries in the form set out in ANNEX 5. 2 REPRESENTATIONS AND WARRANTIES Hydralift represents and warrants to NOI as set forth in ANNEX 6 hereto, it being understood that these representations and warranties will not survive the Closing Date or the termination of this Agreement and that a breach of these representations and warranties will not create any liability for damages but shall only entitle NOI to terminate this Agreement.

As of 10 October, 2002, 8 shareholders representing 22.80 per cent of the shares in Hydralift have granted NOI a call option to acquire the shares at a price equal to the Offer Price. The call option is exercisable until 31 March, 2003 (including). It is the Board of Directors' opinion that the combination of Hydralift and NOI represents a very interesting development for Hydralift. Furthermore, the Board of Directors believe that the employees of Hydralift are content with NOI's offer. [Comment: The employees may issue its own statement. In such situation, it should be assumed that the board statement will refer to the employee statement.] NOI's offer price is NOK xx in cash for each Hydralift share. This represents a premium of xx per cent to the Hydralift share closing price at NOK [ ] on the Oslo Stock

2 Exchange on 10 October, 2002; the day before the Combination Agreement was announced. The Board of Directors has for the purpose of the evaluation of the offer received a separate opinion from Pareto Securities ASA, who has expressed the view, based on the current market conditions, that the price offered is a fair price for the Hydralift shares. Based on an overall evaluation the Board of Directors of Hydralift recommends that the Hydralift shareholders accept the offer from NOI. Such recommendation may, however, subject to the provisions of Section 1.3 of the Combination Agreement, be withdrawn before the end of the Tender Offer Period if there is launched a competing offer and after having obtained advice from its legal counsel, determines in good faith that a failure to so cancel, modify or amend its recommendation would under applicable laws constitute a breach of its fiduciary duties towards the shareholders of Hydralift.. If NOI in such case increases its Offer to or above the competing bid, we will uphold and express our recommendation of the increased Offer from NOI. Further, our recommendation is subject to the fact that all relevant governmental bodies approves the transactions without issuing requirements materially effecting the future business of the companies. The following members of the Board of Directors hold shares in Hydralift: [ ] Furthermore, ( ), the Chief Executive Officer of Hydralift holds xxx shares. The members of the Board of Directors and the Chief executive Officer has granted call options to NOI as far as their own shares are concerned. Hydralift shareholders should note that in the event that more than 90 per cent of the Hydralift shareholders accept the offer, the result will in all probability be that the

3 Hydralift share will no longer be listed on the Oslo Stock Exchange and that the minority shareholders will be redeemed. [ ], [ ], 2002 The Board of Directors of Hydralift

ANNEX 7 - FORM OF CALL OPTION TO NATIONAL OILWELL INC. ("NOI") LETTER AGREEMENT REGARDING CALL OPTION I have reviewed the Combination Agreement ("Agreement") to be entered into between NOI and the Board of Hydralift dated on 10 October, 2002, pursuant to which NOI, subject to the terms and conditions in the Agreement and its Annex 1, will present a voluntary offer ("the Tender Offer") to acquire all the shares in Hydralift ASA ("Hydralift"). Capitilized terms used herein will, unless otherwise stated, have the same meaning as in the Agreement. As of this date I own [ ] Hydralift Shares (the "Option Shares"). Under the Tender Offer, the shareholders will for each Hydralift Share be offered NOK 55 in cash. A. CALL OPTION 1. I hereby grant NOI an option (the "Call Option") to purchase the Option Shares at a price of NOK 55 (the "Option Price") per share.

The Option Premium is payable three (3) business days after this irrevocable undertaking was duly executed by me and received by NOI. NOI may only exercise the Call Option by serving a written exercise notice (the "Exercise Notice") on me during the period beginning on 10 October 2002 and ending on 31 March 2003 (both dates inclusive) (the "Option Exercise Period"). The Call Option may only be exercised in respect of all Option Shares. If the Call Option is not exercised within the Option Exercise Period it shall cease to be exercisable and shall laps. Upon the exercise of the Call Option, where Pareto Securities ASA shall represent the undersigned and First Securities ASA ("First") shall represent NOI,

2 the Option Shares shall be transferred to a VPS book-entry account designated by NOI held by First three (3) business days after NOI having sent the Exercise Notice to me. The Option Price is payable three (3) business days after the relevant shares are registered on the designated VPS account. It is agreed that First shall not have any obligation or liability to fulfill NOI' or my obligations pursuant to this undertaking, cf. the Securities Trading Act Section 11-1. The Option Premium shall be transferred to a bank account designated by me with a Norwegian commercial bank (the "Escrow Account") held by me. The Escrow account shall be pledged and blocked in favor of NOI as set in Schedule 2. The pledge and blocking shall be perfected, and such perfection confirmed to NOI, prior to the transfer of Option Premium. First shall not transfer Option Shares to NOI until the Option Price has been transferred to the Escrow Account. 2. I agree and undertake that as from the date of this undertaking for a period ending on the expiry of the Option Exercise Period that I will not, except pursuant to the Call Option and/or the Tender Offer referred to above, offer, sell, contract to sell, mortgage, charge, deposit, assign, issue options or warrants in respect of, grant any option to purchase or otherwise dispose of, directly or indirectly (whether conditionally or unconditionally), any Hydralift Shares (or any other securities convertible into or exchangeable for Hydralift Shares or which carry rights to subscribe or purchase Hydralift Shares) or enter into any transaction (including a derivative transaction) having an effect on the market in the Hydralift Shares similar to that of a sale or publicly to announce any intention to do any of such things or deposit any Hydralift Shares without the prior written consent of NOI. B. MISCELLANEOUS 3. According to the Hydralift share option scheme (the "Scheme") I am entitled to subscribe for a number of shares in Hydralift in relation to the options granted under the Scheme (the "Option(s)"): a. subject to subparagraph b below, if I exercise any of the Option(s), NOI may also elect to purchase any such Hydralift Shares on the terms and conditions
