-iii- 5 COMBINATION AGREEMENT THIS COMBINATION AGREEMENT (this "Agreement") is entered into as of May 14, 1997, by and between National-Oilwell, Inc., a Delaware corporation ("NOI"), and Dreco Energy Services Ltd., an Alberta corporation ("Dreco"). RECITALS WHEREAS, the respective boards of directors of NOI and Dreco each deem it advisable and in the best interests of their respective stockholders to combine their respective businesses by NOI acquiring shares in the capital stock of Dreco pursuant to this Agreement and the Plan of Arrangement (as hereinafter defined). WHEREAS, in furtherance of such acquisition, the respective boards of directors of NOI and Dreco have approved the transactions contemplated by this Agreement, the board of directors of Dreco has agreed to submit the Plan of Arrangement and the other transactions contemplated hereby to its shareholders and the Court of Queen's Bench of Alberta (the "Court") for approval, and the board of directors of NOI has agreed to submit the Restated NOI Charter (as hereinafter defined) and the other transactions contemplated hereby to its stockholders for approval. WHEREAS, the respective boards of directors of NOI and Dreco have approved and adopted this Agreement and the Plan of Arrangement as a plan of reorganization under Section 368(a)(1) of the Internal Revenue Code of 1986, as amended (the "Code"), and as a reorganization of capital of Dreco under Section 86 of the Income Tax Act (Canada) (the "ITA") for those Dreco shareholders who hold Dreco Common Shares (as hereinafter defined), on capital account. WHEREAS, it is intended that the transactions contemplated hereby will be treated as a "pooling of interests" for accounting purposes. WHEREAS, to induce NOI to enter into this Agreement, contemporaneously herewith Frederick W. Pheasey and Robert L. Phillips, owners of approximately 5.2% of the issued and outstanding Dreco Common Shares, have entered into an agreement (the "Dreco Stockholders Agreement") pursuant to which they have agreed to support the Plan of Arrangement and the other transactions contemplated hereby. WHEREAS, to induce Dreco to enter into this Agreement, contemporaneously herewith DPI Oil Service Partners Limited Partnership, DPI Partners II, First Reserve Fund V1, Limited Partnership, First Reserve Fund V-2 and First Reserve Fund V, Limited Partnership, owners of approximately 52% of the issued and outstanding NOI Common Stock (as hereinafter defined), have entered into an agreement (the "NOI Stockholders Agreement") pursuant to which they have agreed to support the Plan of Arrangement and the other transactions contemplated hereby. NOW, THEREFORE, in consideration of the premises and of the representations, warranties, covenants and agreements herein contained, the parties hereto, intending to be legally bound, agree as follows: 6 ARTICLE I GENERAL 1.1 Plan of Arrangement. As promptly as practicable, Dreco will apply to the Court pursuant to Part 15 of the Business Corporations Act (Alberta) (the "ABCA") for an interim order in form and substance reasonably satisfactory to NOI (the "Interim Order") providing for, among other things, the calling and holding of the Dreco Shareholders Meeting (as hereinafter defined) for the purpose of considering and, if deemed advisable, approving the arrangement (the "Arrangement") under Part 15 of the ABCA and pursuant to this Agreement and the Plan of Arrangement substantially in the form of Exhibit A (the "Plan of Arrangement"). If the Dreco shareholders approve the Arrangement, thereafter Dreco will take the necessary steps to submit the Arrangement to the Court and apply for a final order of the Court approving the Arrangement in such fashion as the Court may direct (the "Final Order"). At 12:01 a.m. (the "Effective Time") on the date (the "Effective Date") shown on the certificate of arrangement issued by the Registrar under the ABCA giving effect to the Arrangement, the following reorganization of capital shall occur and shall be deemed to occur in the following order without any further act or formality: (a) The articles of amalgamation of Dreco shall be amended to authorize an unlimited number of exchangeable shares (the "Exchangeable Shares") and one Class A preferred share (the "Preferred Share"); (b) Dreco shall issue to NOI one Class A Preferred Share in consideration of the issuance to Dreco of one share of common stock, $.01 par value per share, of NOI ("NOI Common Stock"). The stated capital of the Class A Preferred Share shall be equal to the fair market value, as determined by the board of directors of Dreco, of a share of NOI Common Stock. No certificate shall be issued in respect of the Class A Preferred Share; (c) Each of the Dreco Common Shares (other than Dreco Common Shares held by holders who have exercised their rights of dissent in accordance with the Plan of Arrangement and who are ultimately entitled to be paid the fair value for such shares) will be exchanged for a number of Exchangeable Shares at an exchange ratio equal to 1.2 of an Exchangeable Share per Dreco Common Share (the "Exchange Ratio"), and each such holder of Dreco Common Shares will receive that whole number of Exchangeable Shares resulting from the exchange of such holder's Dreco Common Shares. In lieu of fractional Exchangeable Shares, each holder of a Dreco Common Share who otherwise would be entitled to receive a fraction of an Exchangeable Share shall be paid by Dreco a cash amount determined in accordance with the Plan of Arrangement; (d) Upon the exchange referred to in Section 1.1(c), each holder of one or more Dreco Common Shares shall cease to be such a holder, shall have his name removed from the register of holders of Dreco Common Shares and shall (unless held by a holder who has exercised his rights of dissent in accordance with the Plan of Arrangement and who is ultimately entitled to be paid the fair value for such shares) become a holder of the number of fully paid Exchangeable Shares to which he is entitled as a result of the exchange referred to in Section 1.1(c), and such holder's name shall be added to the register of holders of Exchangeable Shares accordingly; (e) The aggregate stated capital of the Exchangeable Shares will be equal to the aggregate stated capital of the Dreco Common Shares immediately prior to the Arrangement that are -2- 7 exchanged pursuant to Section 1.1(c), thereby excluding the stated capital attributed to the fractional shares paid in cash as contemplated in Section 1.1(c); (f) The articles of amalgamation of Dreco shall be amended to reduce the number of authorized Dreco Common Shares to one and the following restriction will be added to the rights, privileges, restrictions and conditions attaching to the Dreco Common Shares: "RESTRICTION. So long as any of the Exchangeable Shares of the Corporation are outstanding, the Corporation shall not at any time without, but may at any time with, the approval of the board of directors of the holder of the common shares issue any further Exchangeable Shares or other shares of the Corporation, except as specifically required in accordance with the rights, privileges, restrictions and conditions attaching to the Exchangeable Shares of the Corporation." (g) The one outstanding Class A Preferred Share will be exchanged for one Dreco Common Share, and the holder thereof shall cease to be a holder of the Class A Preferred Share, shall have its name removed from the register of holders of Class A Preferred Shares and shall become a holder of the one fully paid and non-assessable Dreco Common Share to which it is entitled as a result of the exchange referred to in this Section 1.1(g) and such holder's name shall be added to the register of holders of Dreco Common Shares accordingly; (h) The stated capital of the one Dreco Common Share shall be equal to the stated capital of the one Class A Preferred Share immediately prior to the exchange of such Class A Preferred Share pursuant to Section 1.1(g); (i) The articles of amalgamation of Dreco shall be amended to delete the Class A Preferred Shares from the authorized share capital; and (j) Each of the then outstanding options to purchase Dreco Common Shares (collectively, the "Dreco Options") (which includes without limitation all outstanding options pursuant to private stock option arrangements and all outstanding options granted under Dreco's Amended and Restated 1989 Employee Incentive Stock Option Plan (the "Dreco Option Plan")) will and without any further action on the part of any holder thereof (herein, an "optionholder"), be exchanged for an option to purchase that number of Exchangeable Shares determined by multiplying the number of Dreco Common Shares subject to such Dreco Options at the Effective Time by the Exchange Ratio, at an exercise price per Exchangeable Share equal to the exercise price per share of such Dreco Option immediately prior to the Effective Time, divided by the Exchange Ratio. If the foregoing calculation results in an exchanged Dreco Option being exercisable for a fraction of an Exchangeable Share, then the number of Exchangeable Shares subject to such option will be rounded down to the nearest whole number of shares, and the total exercise price for the option will be reduced by the exercise price of the fractional share. The term, exercisability, vesting schedule, and all other terms and conditions of the Dreco Options will otherwise be unchanged by the provisions of this Section 1.1(j) and shall operate in accordance with their terms. 1.2 Adjustments to Exchange Ratio. (a) The Exchange Ratio shall be adjusted to reflect fully the effect of any stock split, reverse split, stock dividend (including any dividend or distribution -3- 8 of securities convertible into NOI Common Stock or Dreco Common Shares), reorganization, recapitalization or other like change with respect to NOI Common Stock or Dreco Common Shares occurring after the date hereof and prior to the Effective Time. (b) The Exchange Ratio shall also be adjusted pursuant to the following: (i) if the average of the per share closing price on the New York Stock Exchange (the "NYSE") of shares of NOI Common Stock (as reported in the NYSE composite transactions) during the 20 consecutive trading days ending on the fifth trading day prior to the Effective Time (the "Pre-Closing Average Price") shall be less than $36.00 per share, the Exchange Ratio shall be adjusted to equal 1.2 multiplied by a fraction, the numerator of which is $36.00 and the denominator of which is the higher of (A) $33.00 and (B) the Pre-Closing Average Price; and (ii) if the Pre-Closing Average Price shall be greater than $47.25 per share, the Exchange Ratio shall be adjusted to equal 1.2 multiplied by a fraction, the numerator of which is $47.25 and the denominator of which is the Pre-Closing Average Price; provided, however, that Dreco shall have the right to terminate this Agreement in accordance with Section 6.1(k) in the event the Pre-Closing Average Price is less than $33.00 per share and NOI, after Dreco shall have exercised its right to request NOI to do so, elects not to adjust the Exchange Ratio to equal 1.2 multiplied by a fraction, the numerator of which is $36.00, and the denominator of which is the Pre-Closing Average Price. 1.3 Dissenting Shares. Holders of Dreco Common Shares may exercise rights of dissent with respect to such shares in connection with the Arrangement pursuant to and in the manner set forth in Section 184 of the ABCA and Section 3.1 of the Plan of Arrangement (such holders referred to as "Dissenters" or as "Dissenting Shareholders" when referring exclusively to Dreco Shareholders). Dreco shall give NOI (i) prompt notice of any written demands of a right of dissent, withdrawals of such demands, and any other instruments served pursuant to the ABCA and received by Dreco and (ii) the opportunity to participate in all negotiations and proceedings with respect to such rights.

(a) As promptly as practicable after execution of this Agreement, NOI and Dreco shall prepare and file with the United States Securities and Exchange Commission (the "SEC") a preliminary joint management information circular and proxy statement (the "Joint Proxy Statement"), together with any other documents required by the Securities Act of 1933, as amended (the "Securities Act"), or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), in connection with the Arrangement and the other transactions contemplated hereby. The Joint Proxy Statement shall constitute (i) the management information circular of Dreco with respect to the meeting of shareholders of Dreco relating to the Arrangement and the approval of certain matters in connection therewith (the "Dreco Shareholders Meeting") and (ii) the proxy statement of NOI with respect to the meeting of stockholders of NOI with respect to the issuance of NOI Common Stock from time to time upon exchange of the Exchangeable Shares and certain other matters (including the approval of the Restated NOI Charter) relating to the agreements of NOI contained herein (the "NOI Stockholders Meeting"). As promptly as practicable after the preliminary Joint Proxy Statement is cleared by the SEC, NOI and Dreco shall cause the Joint Proxy Statement to be mailed to each company's respective stockholders, as the case may be. If NOI determines on the advice of its outside counsel that it is necessary to file a registration statement (the "Registration Statement") in order to register the NOI Common Stock to be issued from time to time after the Effective Time upon exchange of the Exchangeable Shares, then NOI shall file the Registration Statement with the SEC and, if necessary, maintain the effectiveness of such registration for the period that such Exchangeable Shares remain outstanding and NOI and Dreco shall use their best efforts to cause the Registration Statement to become effective prior to the mailing of the Joint Proxy Statement. Notwithstanding anything herein to the contrary, NOI shall be under no obligation to file the Registration Statement if it shall have determined on the advice of its outside counsel that the issuance of shares of NOI Common Stock upon exchange of the Exchangeable Shares after the Effective Time is exempt from the registration requirements of Section 5 of the Securities Act by virtue of Section 3(a)(9) and/or 3(a)(10) thereof. In connection with such determination, NOI and Dreco shall prepare and file with the SEC a request for no action (the "No Action Request") seeking to confirm the availability of such an exemption. (b) Each party shall promptly furnish to the other party all information concerning such party and its stockholders as may be reasonably required in connection with any action contemplated by this Section 1.6. The Joint Proxy Statement and, if required, the Registration Statement, shall comply in all material respects with all applicable requirements of law. Each of NOI and Dreco will notify the other promptly of the receipt of any comments from the SEC and of any request by the SEC for amendments or supplements to the Joint Proxy Statement or the Registration Statement, if required, or for additional information, and will supply the other with copies of all correspondence with the SEC with respect to the Joint Proxy Statement or the Registration Statement, if required. Whenever any event occurs which should be set forth in an amendment or supplement to the Joint Proxy Statement or the Registration Statement, if required, NOI or Dreco, as the case may be, shall promptly inform the other of such occurrence and cooperate in filing with the SEC, and/or mailing to stockholders of NOI and Dreco, as may be applicable, such amendment or supplement. (c) NOI and Dreco shall take any action required to be taken under any applicable provincial or state securities laws (including "blue sky" laws) in connection with the issuance of the NOI Common Stock and the Arrangement; provided, however, that with respect to the blue sky and Canadian provincial qualifications, neither NOI nor Dreco shall be required to register or qualify as a -5- 10 foreign corporation or reporting issuer where any such entity is not now so registered or qualified except as to matters and transactions arising solely from the offer and sale of the NOI Common Stock or the issuance of the Exchangeable Shares. 1.7 Material Adverse Effect. In this Agreement, the term "Material Adverse Effect" used with respect to any party means any event, change or effect that is materially adverse to the financial condition, properties or business of such party and its subsidiaries, taken as a whole; provided, that a Material Adverse Effect shall not include any decline in backlog between the date hereof and the Effective Date resulting from a failure to receive new orders or any adverse effect resulting from changes in general economic conditions or conditions generally affecting the industries in which NOI or Dreco operate. 1.8 Currency. Unless otherwise specified, all references in this Agreement to "dollars" or "$" shall mean United States dollars.

(a) NOI agrees that all rights to indemnification existing in favor of the present or former directors and officers of Dreco (as such) or any of the Dreco Subsidiaries or present or former directors and officers (as such) of Dreco or any of the Dreco Subsidiaries serving or who served at Dreco's or any of the Dreco Subsidiaries' request as a director, officer, employee, agent or representative of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise (each such present or former director or officer of Dreco or any of the Dreco Subsidiaries, an "Indemnified Party"), as provided in Dreco's charter or bylaws or similar documents of any of the Dreco Subsidiaries in effect as of the date hereof with respect to matters occurring prior to the Effective Time, shall survive and shall continue in full force and effect and without modification for a period of not less than the statutes of limitations applicable to such matters. (b) From and after the Effective Time, NOI and Dreco, jointly and severally, shall and shall cause Dreco to indemnify and hold harmless to the fullest extent permitted under the ABCA, each Indemnified Party against any costs and expenses (including reasonable attorney's fees), judgments, fines, losses, claims and damages and liabilities, and amounts paid in settlement thereof with the consent of the indemnifying party, in connection with any actual or threatened claim, action, suit, proceeding or investigation that is based on, or arises out of, the fact that such person is or was a director or officer of Dreco or any Dreco Subsidiary (including without limitation with respect to any of the transactions contemplated hereby or the Arrangement) or who is serving or who served at Dreco's or any of the Dreco Subsidiaries' request as a director, officer, employee, agent or representative of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Without limiting the foregoing, in the event any such claim, action, suit, proceeding or investigation is brought against any Indemnified Parties, (i) the Indemnified Parties may retain counsel reasonably satisfactory to NOI and, subject to limitations imposed by the ABCA, Dreco shall (or NOI shall cause Dreco to) pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received; and (ii) NOI will use all reasonable efforts to assist in the defense of such matter; provided, however, that neither Dreco nor NOI shall be liable for any settlement effected without its prior written consent which shall not be unreasonably withheld. Any Indemnified Party wishing to claim indemnification under this Section 7.5(b), upon learning of any such claim, action, suit, proceeding or investigation, shall notify NOI (but the failure to so notify shall not relieve a party from any liability which it may have under this Section 7.5(b) except to the extent such failure prejudices such party). The Indemnified Parties as a group may retain only one law firm in any jurisdiction to represent them with respect to each such matter unless such counsel determines that there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more Indemnified Parties, in which event such additional counsel may be required to be retained by the Indemnified Parties. (c) Subject to limitations imposed by the ABCA, Dreco shall (or NOI shall cause Dreco to) pay all expenses, including reasonable attorney's fees, as the same may be incurred by any Indemnified Parties in any action by any Indemnified Party or parties seeking to enforce the indemnity or other obligations provided for in this Section 7.5; provided, however, that Dreco will be entitled to reimbursement for any advances made under this Section 7.5 to any Indemnified Party who ultimately proves unsuccessful in enforcing the indemnity as finally determined by a non-appealable judgment in a court of competent jurisdiction, and payment of such expenses in advance of the final disposition of the action shall be made only upon receipt of any undertaking by the Indemnified Party to reimburse all amounts advanced if such action ultimately proves unsuccessful. (d) For a period of six years after the Effective Date, NOI shall continue in effect director and officer liability insurance for the benefit of the Indemnified Parties in such amounts, and with such deductibles, retained amounts, coverages and exclusions as NOI shall provide for its own directors and officers during such period. (e) This Section 7.5, which shall survive the consummation of this Agreement and the Arrangement, is intended to benefit each person or entity indemnified hereunder. 7.6 Affiliate Agreements. (a) To ensure that the Arrangement will be accounted for as a "pooling of interests" and to ensure compliance with Rule 145 of the rules and regulations promulgated by the SEC and the Securities Act, on or before the date the Joint Proxy Statement is first mailed to each company's respective stockholders Dreco will use its reasonable best efforts to have its Affiliates sign and deliver to NOI the Dreco affiliate agreements in the form of Exhibit E.

ARTICLE 2 ARRANGEMENT SECTION 2.1 ARRANGEMENT. At the Effective Time on the Effective Date, the following reorganization of capital and other transactions shall occur and shall be deemed to occur in the following order without any further act or formality: (a) The Articles of Amalgamation of Dreco shall be amended to (i) create and authorize an unlimited number of Exchangeable Shares and one Class A Preferred Share. (b) Dreco shall issue to National one Class A Preferred Share in consideration of the issuance to Dreco of one share of National Common Stock. The stated capital of the Class A Preferred Share shall be equal to the fair market value, as determined by the board of directors of Dreco, of a share of National Common Stock. No certificate shall be issued in respect of the Class A Preferred Share. (c) Each Dreco Common Share (other than Dreco Common Shares held by holders who have exercised their rights of dissent in accordance with Section 3.1 hereof and who are ultimately entitled to be paid the fair value for such shares and other than Dreco Common Shares held by National or any Subsidiary thereof) will be exchanged at the Exchange Ratio for a number of Exchangeable Shares, and each such holder thereof will receive a whole number of Exchangeable Shares resulting therefrom. In lieu of fractional Exchangeable Shares, each such holder who otherwise would be entitled to receive a fraction of an Exchangeable Share on the exchange shall be paid by Dreco an amount determined as set forth in Section 4.3. 52 - 5 - (d) Upon the exchange referred to in subsection (c) above, each such holder of a Dreco Common Share shall cease to be such a holder, shall have hisname removed from the register of holders of Dreco Common Shares and shall become a holder of the number of fully paid Exchangeable Shares to which he is entitled as a result of the exchange referred to in subsection (c), and such holder's name shall be added to the register of holders of Exchangeable Shares accordingly. (e) The aggregate stated capital of the Exchangeable Shares will be equal to the aggregate stated capital immediately prior to the Effective Date of the Dreco Common Shares which are exchanged pursuant to such subsection 2.1(c) above, thereby excluding the stated capital attributable to the fractional shares for which payment is made as contemplated in subsection (c) above. (f) The Articles of Amalgamation of Dreco shall be amended to reduce the number of authorized Dreco Common Shares to one and the following restriction will be added to the rights, privileges, restrictions and conditions attaching to the Dreco Common Shares: "RESTRICTION" So long as any of the Exchangeable Shares of the Corporation are outstanding, the Corporation shall not at any time without, but may at any time with, the approval of the board of directors of the holder of the common shares issue any further Exchangeable Shares of the Corporation, except as specifically required in accordance with the rights, privileges, restrictions and conditions attaching to the Exchangeable Shares of the Corporation." (g) The one outstanding Class A Preferred Share will be exchanged for one fully-paid and non-assessable Dreco Common Share and the holder thereof shall cease to be a holder of the Class A Preferred Share, shall have its name removed from the register of holders of Class A Preferred Shares and shall become a holder of the Dreco Common Share to which it is entitled as a result of the exchange referred to in this subsection (g), and such holder's name shall be added to the register as holder of the Dreco Common Share accordingly. (h) The stated capital of the one Dreco Common Share shall be equal to the stated capital of the one Class A Preferred Share immediately prior to the exchange contemplated in subsection (g). (i) The Articles of Amalgamation of Dreco shall be amended to delete the Class A Preferred Share from the authorized share capital. 53 - 6 - (j) Each of the then outstanding Options will, without any further action on the part of any Optionholder, be exchanged for an option to purchase the number of Exchangeable Shares determined by multiplying the number of Dreco Common Shares subject to such Option at the Effective Time by the Exchange Ratio, at an exercise price per Exchangeable Share equal to the exercise price per share of such Option immediately prior to the Effective Time divided by the Exchange Ratio. If the foregoing calculation results in an exchanged Option being exercisable for a fraction of an Exchangeable Share, then the number of Exchangeable Shares subject to such Option will be rounded down to the nearest whole number of shares, and the total exercise price for the Option will be reduced by the exercise price of the fractional share. The term, exercisability, vesting schedule, and all other terms and conditions of the Options will otherwise be unchanged by the provisions of this paragraph (j) and shall operate in accordance with their terms. (k) All rights outstanding under the Shareholder Rights Plan Agreement between Dreco and Montreal Trust Company of Canada dated as of November 15, 1996 (the "Rights Plan") immediately prior to the Effective Date shall, on the Effective Date, be redeemed and cancelled, all on the terms and with the effects and results contained in the Rights Plan, and the Rights Plan shall be terminated.

To effect such redemption, the holder shall present and surrender at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation by notice to the holders of Exchangeable Shares the certificate or certificates representing the Exchangeable Shares which the holder desires to have the Corporation redeem, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the by-laws of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require, and together with a duly executed statement (the "RETRACTION REQUEST") in the form of Schedule A hereto or in such other form as may be acceptable to the Corporation: (i) specifying that the holder desires to have all or any number specified therein of the Exchangeable Shares represented by such certificate or certificates (the "RETRACTED SHARES") redeemed by the Corporation; (ii) stating the Business Day on which the holder desires to have the Corporation redeem the Retracted Shares (the "RETRACTION DATE"), provided that the Retraction Date shall be not less than five Business Days nor more than 10 Business Days after the date on which the Retraction Request is received by the Corporation and further provided that, in the event that no such Business Day is specified by the holder in the Retraction Request, the Retraction Date shall be deemed to be the tenth Business Day after the date on which the Retraction Request is received by the Corporation; and (iii) acknowledging the overriding right (the "RETRACTION CALL RIGHT") of National to purchase all but not less than all the Retracted Shares directly from the holder and that the Retraction Request shall be deemed to be a revocable offer 70 - 10 - by the holder to sell the Retracted Shares in accordance with the Retraction Call Right on the terms and conditions set out in Section 6.3 below. 6.2 Subject to the exercise by National of the Retraction Call Right, upon receipt by the Corporation or the Transfer Agent in the manner specified in Section 6.1 hereof of a certificate or certificates representing the number of Exchangeable Shares which the holder desires to have the Corporation redeem, together with a Retraction Request, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7, the Corporation shall redeem the Retracted Shares effective at the close of business on the Retraction Date and shall cause to be delivered to such holder the total Retraction Price with respect to such shares in accordance with Section 6.4 hereof. If only a part of the Exchangeable Shares represented by any certificate are redeemed or purchased by National pursuant to the Retraction Call right, a new certificate for the balance of such Exchangeable Shares shall be issued to the holder at the expense of the Corporation. 6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation shall immediately notify National thereof. In order to exercise the Retraction Call Right, National must notify the Corporation in writing of its determination to do so (the "NATIONAL CALL NOTICE") within two Business Days of such notification. If National does not so notify the Corporation within two Business Days, the Corporation will notify the holder as soon as possible thereafter that National will not exercise the Retraction Call Right. If National delivers the National Call Notice within such two Business Days, and provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7, the Retraction Request shall thereupon be considered only to be an offer by the holder to sell the Retracted Shares to National in accordance with the Retraction Call Right. In such event, the Corporation shall not redeem the Retracted Shares and National shall purchase from such holder and such holder shall sell to National on the Retraction Date the Retracted Shares for a purchase price (the "PURCHASE PRICE") per share equal to the Retraction Price per share. For the purposes of completing a purchase pursuant to the Retraction Call Right, National shall deposit with the Transfer Agent, on or before the Retraction Date the Exchangeable Share Consideration representing the total Purchase Price. Provided that such Exchangeable Share Consideration has been so deposited with the Transfer Agent, the closing of the purchase and sale of the Retracted Shares pursuant to the Retraction Call Right shall be deemed to have occurred as at the close of business on the Retraction Date and, for greater certainty, no redemption by the Corporation of such Retracted Shares shall take place on the Retraction Date. In the event that National does not deliver a National Call Notice within two Business Days or otherwise comply with these Exchangeable Share provisions in respect thereto, and provided that Retraction Request is not revoked by the holder in the manner specified in Section 6.7, the Corporation shall redeem the Retracted Shares on the Retraction Date and in the manner otherwise contemplated in this Article 6. 71 - 11 - 6.4 The Corporation or National, as the case may be, shall deliver or cause the Transfer Agent to deliver to the relevant holder, at the address of the holder recorded in the securities register of the Corporation for the Exchangeable Shares or at the address specified in the holder's Retraction Request or by holding for pick up by the holder at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation by notice to the holders of Exchangeable Shares, the Exchangeable Share Consideration representing the total Retraction Price or the total Purchase Price, as the case may be, and such delivery of such Exchangeable Share Consideration to the Transfer Agent shall be deemed to be payment of and shall satisfy and discharge all liability for the total Retraction Price or total Purchase Price, as the case may be, except as to any cheque included therein which is not paid on due presentation. 6.5 On and after the close of business on the Retraction Date, the holder of the Retracted Shares shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total Retraction Price or total Purchase Price, as the case may be, unless upon presentation and surrender of certificates in accordance with the foregoing provisions, payment of the total Retraction Price or the total Purchase Price, as the case may be, shall not be made, in which case the rights of such holder shall remain unaffected until the total Retraction Price or the total Purchase Price, as the case may be, has been paid in the manner hereinbefore provided. On and after the close of business on the Retraction Date, provided that presentation and surrender of certificates and payment of the total Retraction Price or the total Purchase Price, as the case may be, has been made in accordance with the foregoing provisions, the holder of the Retracted Shares so redeemed by the Corporation or purchased by National shall thereafter be considered and deemed for all purposes to be a holder of the National Common Stock delivered to it. Notwithstanding the foregoing, until payment of such Exchangeable Share Consideration to the holder, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 6.6 Notwithstanding any other provision of this Article 6, the Corporation shall not be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent that such redemption of Retracted Shares would be contrary to liquidity or solvency requirements or other provisions of applicable law. If the Corporation believes that on any Retraction Date it would not be permitted by any of such provisions to redeem the Retracted Shares tendered for redemption on such date, and provided that National shall not have exercised the Retraction Call Right with respect to the Retracted Shares, the Corporation shall only be obligated to redeem Retracted Shares specified by a holder in a Retraction Request to the extent of the maximum number that may be so redeemed (rounded down to a whole number of shares) as would not be contrary to such provisions and shall notify the holder at least two Business Days prior to the Retraction Date as to the number of Retracted Shares which will not be redeemed by the Corporation. In any case in which the redemption by the Corporation of Retracted Shares would be contrary to liquidity or solvency requirements or other provisions of applicable law, the Corporation 72 - 12 - shall redeem Retracted Shares in accordance with Section 6.2 of these share provisions on a pro rata basis and shall issue to each holder of Retracted Shares a new certificate, at the expense of the Corporation, representing the Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 hereof. Provided that the Retraction Request is not revoked by the holder in the manner specified in Section 6.7, the holder of any such Retracted Shares not redeemed by the Corporation pursuant to Section 6.2 of these share provisions as a result of liquidity or solvency requirements or applicable law shall be deemed by giving the Retraction Request to require National to purchase such Retracted Shares from such holder on the Retraction date or as soon as practicable thereafter on payment by National to such holder of the Purchase Price for each such Retracted Share, all as more specifically provided in the Voting and Exchange Trust Agreement, and National shall make such purchase. 6.7 A holder of Retracted Shares may, by notice in writing given by the holder to the Corporation before the close of business on the Business Day immediately preceding the Retraction Date, withdraw its Retraction Request in which event such Retraction Request shall be null and void and, for greater certainty, the revocable offer constituted by the Retraction Request to sell the Retracted Shares to National shall be deemed to have been revoked. ARTICLE 7 REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION 7.1 Subject to applicable law, and if National does not exercise the Redemption Call Right, the Corporation shall on the Automatic Redemption Date redeem the whole of the then outstanding Exchangeable Shares for an amount equal to the Exchangeable Share Price applicable on the last Business Day prior to the Automatic Redemption Date (the "REDEMPTION PRICE"). In connection with payment of the Redemption Price, the Corporation shall be entitled to liquidate some of the National Common Stock which would otherwise be deliverable to the particular holder of Exchangeable Shares in order to fund any statutory withholding tax obligation. 7.2 In any case of a redemption of Exchangeable Shares under this Article 7, the Corporation shall, at least 120 days before the Automatic Redemption Date, send or cause to be sent to each holder of Exchangeable Shares a notice in writing of the redemption by the Corporation or the purchase by National under the Redemption Call Right, as the case may be, of the Exchangeable Shares held by such holder. Such notice shall set out the formula for determining the Redemption Price or the Redemption Call Purchase Price, as the case may be, the Automatic Redemption Date and, if applicable, particulars of the Redemption Call Right. 73 - 13 - 7.3 On or after the Automatic Redemption Date and subject to the exercise by National of the Redemption Call Right, the Corporation shall cause to be delivered to the holders of the Exchangeable Shares to be redeemed the Redemption Price for each such Exchangeable Share upon presentation and surrender at the registered office of the Corporation or at any office of the Transfer Agent as may be specified by the Corporation in such notice of the certificates representing such Exchangeable Shares, together with such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the by-laws of the Corporation and such additional documents and instruments as the Transfer Agent may reasonably require. Payment of the total Redemption Price for such Exchangeable Shares shall be made by delivery to each holder, at the address of the holder recorded in the securities register or at any office of the Transfer Agent as may be specified by the Corporation in such notice, on behalf of the Corporation of the Exchangeable Share Consideration representing the total Redemption Price. On and after the Automatic Redemption Date, the holders of the Exchangeable Shares called for redemption shall cease to be holders of such Exchangeable Shares and shall not be entitled to exercise any of the rights of holders in respect thereof, other than the right to receive their proportionate part of the total Redemption Price, unless payment of the total Redemption Price for such Exchangeable Shares shall not be made upon presentation and surrender of certificates in accordance with the foregoing provisions, in which case the rights of the holders shall remain unaffected until the total Redemption Price has been paid in the manner hereinbefore provided. The Corporation shall have the right at any time after the sending of notice of its intention to redeem the Exchangeable Shares as aforesaid to deposit or cause to be deposited the Exchangeable Share Consideration with respect to the Exchangeable Shares so called for redemption, or of such of the said Exchangeable Shares represented by certificates that have not at the date of such deposit been surrendered by the holders thereof in connection with such redemption, in a custodial account or for safe keeping, in the case of non-cash items, with any chartered bank or trust company in Canada named in such notice. Upon the later of such deposit being made and the Automatic Redemption Date, the Exchangeable Shares in respect whereof such deposit shall have been made shall be redeemed and the rights of the holders thereof after such deposit or Automatic Redemption Date, as the case may be, shall be limited to receiving their proportionate part of the total Redemption Price for such Exchangeable Shares so deposited, against presentation and surrender of the said certificates held by them, respectively, in accordance with the foregoing provisions. Upon such payment or deposit of such Exchangeable Share Consideration, the holders of the Exchangeable Shares shall thereafter be considered and deemed for all purposes to be holders of the National Common Stock delivered to them. Notwithstanding the foregoing, until such payment or deposit of such Exchangeable Share Consideration is made, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. 74 - 14 - ARTICLE 8 EXCHANGE PUT RIGHT 8.1 Upon and subject to the terms and conditions contained in the Exchangeable Share Provisions and the Voting and Exchange Trust Agreement: (a) a holder of Exchangeable Shares shall have the right (the "Exchange Put Right") at any time to require National to purchase all or any part of the Exchangeable Shares of the holder; and (b) upon the exercise by the holder of the Exchange Put Right, the holder shall be required to sell to National, and National shall be required to purchase from the holder, that number of Exchangeable Shares in respect of which the Exchange Put Right is exercised, in consideration of the payment by National of the Exchangeable Share Price applicable thereto (which shall be the Exchangeable Share Price applicable on the last Business Day prior to receipt of notice required under section 8.2) and delivery by or on behalf of National of the Exchangeable Share Consideration representing the total applicable Exchangeable Share Price. 8.2 The Exchange Put Right provided in section 8.1 hereof and in Article V of the Voting and Exchange Trust Agreement may be exercised at any time by notice in writing given by the holder to and received by the Trustee (the date of such receipt, the "Exchange Put Date") accompanied by presentation and surrender of the certificates representing such Exchangeable Shares, together with such documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the by-laws of the Corporation and such additional documents and instruments as the Trustee may reasonably require, at the principal transfer office in Calgary, Alberta of the Trustee, or at such other office or offices of the Trustee or of other persons designated by the Trustee for that purpose as may from time to time be maintained by the Trustee for that purpose. Such notice may be in the form of the panel, if any, on the certificates representing Exchangeable Shares, or other form satisfactory to the Trustee (or such other persons aforesaid), shall stipulate the number of Exchangeable Shares in respect of which the right is exercised (which may not exceed the number of shares represented by certificates surrendered to the Trustee), shall be irrevocable unless the exchange is not completed in accordance herewith and with the Voting and Exchange Trust Agreement and shall constitute the holder's authorization to the Trustee (and such other persons aforesaid) to effect the exchange on behalf of the holder. 8.3 The surrender by the holder of Exchangeable Shares under section 8.2 shall constitute the representation, warranty and covenant of the holder that the Exchangeable Shares so purchased are sold free and clear of any lien, encumbrance, security interest or adverse claim or interest. 75 - 15 - 8.4 If a part only of the Exchangeable Shares represented by any certificate are to be sold and purchased pursuant to the exercise of the Exchange Put Right, a new certificate for the balance of such Exchangeable Shares shall be issued to the holder at the expense of the Corporation. 8.5 Upon receipt by the Trustee of the notice, certificates and other documents or instruments required by section 8.2, the Trustee shall deliver or cause to be delivered, on behalf of National and subject to receipt by the Trustee from National of the applicable Exchangeable Share Consideration, to the relevant holder at the address of the holder specified in the notice or by holding for pick-up by the holder at the registered office of the Corporation or at any office of the Trustee (or other persons aforesaid) maintained for that purpose, the Exchangeable Share Consideration representing the total applicable Exchangeable Share Price. Delivery by National to the Trustee of such Exchangeable Share Consideration shall be deemed to be payment of and shall satisfy and discharge all liability for the total applicable Exchangeable Share Price, except as to any cheque included therein which is not paid on due presentation. 8.6 On and after the close of business on the Exchange Put Date, the holder of the Exchangeable Shares in respect of which the Exchange Put Right is exercised shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive the total applicable Exchangeable Share Price, unless upon presentation and surrender of certificates in accordance with the foregoing provisions, payment of such total price shall not be made, in which case the rights of such holder shall remain unaffected until such payment has been made. On and after the close of business on the Exchange Put Date provided that presentation and surrender of certificates and payment of such total price has been made in accordance with the foregoing provisions, the holder of the Exchangeable Shares so purchased by National shall thereafter be considered and deemed for all purposes to be a holder of the National Common Stock delivered to it. Notwithstanding the foregoing, until payment of such total price to the holder, the holder shall be deemed to still be a holder of Exchangeable Shares for purposes of all voting rights with respect thereto under the Voting and Exchange Trust Agreement. ARTICLE 9 VOTING RIGHTS 9.1 Except as required by applicable law and the provisions hereof, the holders of the Exchangeable Shares shall not be entitled as such to receive notice of or to attend any meeting of the shareholders of the Corporation or to vote at any such meeting. 76 - 16 - ARTICLE 10 AMENDMENT AND APPROVAL 10.1 The rights, privileges, restrictions and conditions attaching to the Exchangeable Shares may be added to, changed or removed but, except as hereinafter provided, only with the approval of the holders of the Exchangeable Shares given as hereinafter specified. 10.2 Any approval given by the holders of the Exchangeable Shares to add to, change or remove any right, privilege, restriction or condition attaching to the Exchangeable Shares or any other matter requiring the approval or consent of the holders of the Exchangeable Shares shall be deemed to have been sufficiently given if it shall have been given in accordance with applicable law subject to a minimum requirement that such approval be evidenced by resolution passed by not less than 66 2/3% of the votes cast on such resolution by persons represented in person or by proxy at a meeting of holders of Exchangeable Shares duly called and held at which the holders of at least 50% of the outstanding Exchangeable Shares at that time are present or represented by proxy (excluding Exchangeable Shares beneficially owned by National or its Subsidiaries). If at any such meeting the holders of at least 50% of the outstanding Exchangeable Shares at that time are not present or represented by proxy within one-half hour after the time appointed for such meeting then the meeting shall be adjourned to such date not less than 10 days thereafter and to such time and place as may be designated by the Chairman of such meeting. At such adjourned meeting the holders of Exchangeable Shares present or represented by proxy thereat may transact the business for which the meeting was originally called and a resolution passed thereat by the affirmative vote of not less than 66 2/3% of the votes cast on such resolution by persons represented in person or by proxy at such meeting shall constitute the approval or consent of the holders of the Exchangeable Shares. For the purposes of this section, any spoiled votes, illegible votes, defective votes and abstinences shall be deemed to be votes not cast. ARTICLE 11 RECIPROCAL CHANGES, ETC. IN RESPECT OF NATIONAL COMMON STOCK 11.1 (a) Each holder of an Exchangeable Share acknowledges that the Support Agreement provides, in part, that National will not without the prior approval of the Corporation and the prior approval of the holders of the Exchangeable Shares given in accordance with Section 10.1 of these share provisions: (i) issue or distribute National Common Stock (or securities exchangeable for or convertible into or from which may be derived National 77 - 17 - Common Stock) to the holders of all or substantially all of the then outstanding National Common Stock by way of stock dividend or other distribution; or (ii) issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding National Common Stock entitling them to subscribe for or to purchase shares of National Common Stock (or securities exchangeable for or convertible into or carrying rights to acquire shares of National Common Stock); or (iii) issue or distribute to the holders of all or substantially all of the then outstanding shares of National Common Stock (A) shares or securities of National of any class other than National Common Stock (other than shares convertible into or exchangeable for or carrying rights to acquire National Common Stock), (B) rights, options or warrants other than those referred to in subsection 11.1(a)(ii) above, (C) evidences of indebtedness of National or (D) assets of National; unless the Corporation is permitted under applicable law to issue and distribute the economic equivalent on a per share basis of such rights, options, warrants, securities, shares, evidences of indebtedness or assets and the items referred to in clauses (i), (ii) and (iii) above, as applicable, are issued or distributed simultaneously to holders of Exchangeable Shares.

At the time of each Distribution, such Distribution shall be made to the holders of Class A Common Stock and Common Stock in the following priority: (i) The holders of Class A Common Stock shall be entitled to receive all or a portion of such Distribution (ratably among such holders based upon the number of shares of Class A Common Stock held by each such holder as of the time of such Distribution) equal to the aggregate Unreturned Original Cost of the outstanding shares of Class A Common Stock as of the time of such Distribution, and no Distribution or any portion thereof shall be made under Section 2(ii) below until the entire amount of Unreturned Original Cost of the outstanding shares of Class A Common Stock as of the time of such Distribution has been paid in full. The Distributions made pursuant to this paragraph 2(i) to holders of Class A Common Stock shall constitute a return of Original Cost of Class A Common Stock. (ii) After the holders of Class A Common Stock have received Distributions equal to the entire Original Cost thereof pursuant to paragraph 2(i) above, holders of Common Shares as a group, shall be entitled to receive the remaining portion of such Distribution (ratably among such holders based upon the number of Common Shares held by each such holder as of the time of such Distribution). (iii) If the Corporation is a party to a merger or consolidation in which the stockholders of the Corporation receive Merger Consideration, all of the Merger Consideration shall be deemed to be a Distribution for purposes of allocating all of such Merger Consideration between the holders of Class A Common Stock and the holders of Common Stock under this Section 2. SECTION 4. STOCK SPLITS AND STOCK DIVIDENDS. The Corporation shall not in any manner subdivide (by stock split, stock dividend or otherwise) or combine (by stock split, stock dividend or otherwise) the outstanding Common Shares of one class unless the outstanding Common Shares of the other class shall be proportionately subdivided or combined. All such subdivisions and combinations shall be payable only in Class A Common Stock to the holders of Class A Common Stock and in Common Stock to the holders of Common Stock. In no event shall a stock split or stock dividend constitute a return of Original Cost. SECTION 5. CONVERSION. Immediately prior to the Public Offering Time, each share of Class A Common Stock outstanding immediately prior to the Public Offering Time shall be, without further action by the Corporation or the holder thereof, changed and converted into a number of shares of Common Stock equal to the sum of the Unreturned Original Cost on each such share of Class A Common Stock as of the Public Offering Time divided by the Net Public Offering Price. Each certificate -2- 86 representing shares of Class A Common Stock shall automatically represent from and after the Public Offering Time that number of shares of Common Stock into which such shares of Class A Common Stock have been converted pursuant to the preceding sentence. When shares of Class A Common Stock have been converted pursuant to this Section 4, they shall be irrevocably canceled and not reissued. Following conversion of all of the shares of Class A Common Stock, no other shares of Class A Common Stock shall be issued, at any time, by the Corporation. SECTION 6. REGISTRATION OF TRANSFER. The Corporation shall keep at its principal office (or such other place as the Corporation reasonably designates) a register for the registration of Common Shares. Upon the surrender of any certificate representing shares of any class of Common Shares at such place, the Corporation shall, at the request of the registered holder of such certificate, execute and deliver a new certificate or certificates in exchange therefor representing in the aggregate the number of shares of such class represented by the surrendered certificate, and the Corporation forthwith shall cancel such surrendered certificate. Each such new certificate will be registered in such name and will represent such number of shares of such class as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate. The issuance of new certificates shall be made without charge to the holders of the surrendered certificates for any issuance tax in respect thereof or other cost incurred by the Corporation in connection with such issuance. SECTION 7. REPLACEMENT. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder will be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing one or more shares of any class of Common Shares, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement will be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of such class represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate. SECTION 8. NOTICES. All notices referred to herein shall be in writing, shall be delivered personally or by first class mail, postage prepaid, and shall be deemed to have been given when so delivered or mailed to the Corporation at its principal executive offices and to any stockholder at such holder's address as it appears in the stock records of the Corporation (unless otherwise specified in a written notice to the Corporation by such holder). SECTION 9. AMENDMENT AND WAIVER. No amendment or waiver of any provision of this Article Fourth shall be effective without the prior written consent of the holders of a majority of the then outstanding Common Shares voting as a single class; provided that no amendment as to any terms or provisions of, or for the benefit of, any class of Common Shares that adversely affects the powers, preferences or special rights of such class of Common Shares shall be effective without the prior consent of the holders of a majority of the then outstanding shares of such affected class of Common Shares, voting as a single class. -3- 87 III.

"ORIGINAL COST" of each share of Class A Common Stock shall be equal to the amount originally paid for such share when it was issued by the Corporation (as proportionally adjusted for all stock splits, stock dividends and other recapitalizations affecting the Class A Common Stock), all such shares shall be deemed to have an Original Cost equal to $24,900 per share (as proportionally adjusted for all stock splits, stock dividends and other recapitalizations affecting the Class A Common Stock).

The board of directors of the Corporation may increase the number of shares of the Preferred Stock designated for any existing class or series by a resolution adding to such class or series authorized and unissued shares of the Preferred Stock not designated for any other class or series. The board of directors of the Corporation may decrease the number of shares of the Preferred Stock designated for any existing class or series by a resolution subtracting from such class or series authorized and unissued shares of the Preferred Stock designated for such existing class or series, and the shares so subtracted shall become authorized, unissued, and undesignated shares of the Preferred Stock.

V. NO PREEMPTIVE RIGHTS No holder of shares of stock of the Corporation shall have any preemptive or other rights, except such rights as are expressly provided by contract, to purchase or subscribe for or receive any shares of any class, or series thereof, of stock of the Corporation, whether now or hereafter authorized, or any warrants, options, bonds, debentures or other securities convertible into, exchangeable for or carrying any right to purchase any shares of any class, or series thereof, of stock; but such additional shares of stock and such warrants, options, bonds, debentures or other securities convertible into, exchangeable for or carrying any right to purchase any shares of any class, or series thereof, of stock may be issued or disposed of by the board of directors to such persons, and on such terms and for such lawful consideration, as in its discretion it shall deem advisable or as to which the Corporation shall have by binding contract agreed. VI. REGISTERED OWNER The Corporation shall be entitled to treat the person in whose name any share of its stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the Corporation shall have notice thereof, except as expressly provided by applicable law. VII. GENERAL Subject to the foregoing provisions of this Amended and Restated Certificate of Incorporation, the Corporation may issue shares of its Preferred Stock and Common Stock from time to time for such consideration (not less than the par value thereof) as may be fixed by the board of directors of the Corporation, which is expressly authorized to fix the same in its absolute discretion subject to the foregoing conditions. Shares so issued for which the consideration shall have been paid or delivered to the Corporation shall be deemed fully paid stock and shall not be liable to any further call or assessment thereon, and the holders of such shares shall not be liable for any further payments in respect of such shares. The Corporation shall have authority to create and issue rights and options entitling their holders to purchase shares of the Corporation's capital stock of any class or series or other securities of the -6- 90 Corporation, and such rights and options shall be evidenced by instrument(s) approved by the board of directors of the Corporation. The board of directors of the Corporation shall be empowered to set the exercise price, duration, times for exercise, and other terms of such rights or options; provided, however, that the consideration to be received for any shares of capital stock subject thereto shall not be less than the par value thereof. FIFTH: The following provisions are inserted for the management of the business and for the conduct of the affairs of the Corporation, and for further definition, limitation and regulation of the powers of the Corporation and of its directors and stockholders: I. DIRECTORS The number, classification, and terms of the board of directors of the Corporation and the procedures to elect directors, to remove directors, and to fill vacancies in the board of directors shall be as follows: (a) The number of directors that shall constitute the whole board of directors shall from time to time be fixed exclusively by the board of directors by a resolution adopted by a majority of the whole board of directors serving at the time of that vote. In no event shall the number of directors that constitute the whole board of directors be fewer than three. No decrease in the number of directors shall have the effect of shortening the term of any incumbent director. Directors of the Corporation need not be elected by written ballot unless the by-laws of the Corporation otherwise provide. (b) The board of directors of the Corporation shall be divided into three classes designated Class I, Class II, and Class III, respectively, all as nearly equal in number as possible, with each director then in office receiving the classification that at least a majority of the board of directors designates. The initial term of office of directors of Class I shall expire at the annual meeting of stockholders of the Corporation in 1997, of Class II shall expire at the annual meeting of stockholders of the Corporation in 1998, and of Class III shall expire at the annual meeting of stockholders of the Corporation in 1999, and in all cases as to each director until his successor is elected and qualified or until his earlier death, resignation or removal. At each annual meeting of stockholders beginning with the annual meeting of stockholders in 1997, each director elected to succeed a director whose term is then expiring shall hold his office until the third annual meeting of stockholders after his election and until his successor is elected and qualified or until his earlier death, resignation or removal. If the number of directors that constitutes the whole board of directors is changed as permitted by this Article V, the majority of the whole board of directors that adopts the change shall also fix and determine the number of directors comprising each class; provided, however, that any increase or decrease in the number of directors shall be apportioned among the classes as equally as possible. (c) Vacancies in the board of directors resulting from death, resignation, retirement, disqualification, removal from office, or other cause and newly-created directorships resulting from any increase in the authorized number of directors may be filled by no less than a majority vote of the remaining directors then in office, though less than a quorum, who are designated to represent the same class or classes of stockholders that the vacant position, when filled, is to represent or by the sole remaining director (but not by the stockholders except as required by -7- 91 law), and each director so chosen shall receive the classification of the vacant directorship to which he has been appointed or, if it is a newly-created directorship, shall receive the classification that at least a majority of the board of directors designates and shall hold office until the first meeting of stockholders held after his election for the purpose of electing directors of that classification and until his successor is elected and qualified or until his earlier death, resignation, or removal from office. (d) A director of any class of directors of the Corporation may be removed before the expiration date of that director's term of office, only for cause, by an affirmative vote of the holders of not less than eighty percent (80%) of the votes of the outstanding shares of the class or classes or series of stock then entitled to be voted at an election of directors of that class or series, voting together as a single class, cast at the annual meeting of stockholders or at any special meeting of stockholders called by a majority of the whole board of directors for this purpose. II. POWER TO AMEND BY-LAWS The by-laws may be altered or repealed and new by-laws may be adopted (a) at any annual or special meeting of stockholders if notice of the proposed alteration, repeal or adoption of the new by-law or by-laws be contained in the notice of such annual or special meeting by the affirmative vote of a majority of the stock issued and outstanding and entitled to vote thereat, voting together as a single class, or (b) by the affirmative vote of a majority of the members present at any regular meeting of the board of directors, or at any special meeting of the board of directors, without any action on the part of the stockholders, if notice of the proposed alteration, repeal or adoption of the new by-law or by-laws be contained in the notice of such regular or special meeting. III. STOCKHOLDERS' ACTION -- SPECIAL MEETINGS After October 15, 1996, no action required to be taken or that may be taken at any meeting of common stockholders of the Corporation may be taken without a meeting, and, after such date, the power of common stockholders to consent in writing, without a meeting, to the taking of any action is specifically denied. Special meetings of the stockholders of the Corporation, and any proposals to be considered at such meetings, may be called and proposed exclusively by (i) the Chairman of the Board, (ii) the President or (iii) the board of directors, pursuant to a resolution approved by a majority of the members of the board of directors at the time in office, and no stockholder of the Corporation shall require the board of directors to call a special meeting of common stockholders or to propose business at a special meeting of stockholders. Except as otherwise required by law or regulation, no business proposed by a stockholder to be considered at an annual meeting of the stockholders (including the nomination of any person to be elected as a director of the Corporation) shall be considered by the stockholders at that meeting unless, no later than ninety (90) days before the annual meeting of stockholders or (if later) ten days after the first public notice of that meeting is sent to stockholders, the Corporation receives from the stockholder proposing that business a written notice that sets forth (1) the nature of the proposed business with reasonable particularity, including the exact text of any proposal to be presented for adoption, and the reasons for conducting that business at the annual meeting; (2) with respect to each such stockholder, that stockholder's name and address (as they appear on the records of the Corporation), business address -8- 92 and telephone number, residence address and telephone number, and the number of shares of each class of stock of the Corporation beneficially owned by that stockholder; (3) any interest of the stockholder in the proposed business; (4) the name or names of each person nominated by the stockholder to be elected or re-elected as a director, if any; and (5) with respect to each nominee, that nominee's name, business address and telephone number, and residence address and telephone number, the number of shares, if any, of each class of stock of the Corporation owned directly and beneficially by that nominee, and all information relating to that nominee that is required to be disclosed in solicitations of proxies for elections of directors, or is otherwise required, pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the AExchange Act") (or any provision of law subsequently replacing Regulation 14A), together with a duly acknowledged letter signed by the nominee stating his or her acceptance of the nomination by that stockholder, stating his or her intention to serve as director if elected, and consenting to being named as a nominee for director in any proxy statement relating to such election. The person presiding at the annual meeting shall determine whether business (including the nomination of any person as a director) has been properly brought before the meeting and, if the facts so warrant, shall not permit any business (or voting with respect to any particular nominee) to be transacted that has not been properly brought before the meeting. Notwithstanding any other provisions of this Amended and Restated Certificate of Incorporation or any provision of law that might otherwise permit a lesser or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the capital stock of the Corporation required by law or by this Amended and Restated Certificate of Incorporation, the affirmative vote of the holders of not less than eighty percent (80%) of the shares of the Corporation then entitled to be voted in an election of directors, voting together as a single class, shall be required to amend or repeal, or to adopt any provision inconsistent with, this Article Fifth. SIXTH: ELIMINATION OF CERTAIN LIABILITY OF DIRECTORS AND INDEMNIFICATION I. ELIMINATION OF CERTAIN LIABILITY OF DIRECTORS No director shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty by such director as a director, except for liability (a) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the General Corporation Law of the State of Delaware, or (d) for any transaction from which the director derived an improper personal benefit. Any amendment or repeal of this Part I of this Article Sixth shall be prospective only, and neither the amendment nor repeal of this Part I of this Article Sixth shall eliminate or reduce the effect of this Part I of this Article Sixth in respect of any matter occurring, or any cause of action, suit or claim that, but for this Part I of this Article Sixth would accrue or arise, prior to such amendment or repeal. If the Delaware General Corporation Law hereafter is amended to authorize corporate action further eliminating or limiting the liability of directors, then the liability of a director of the Corporation, in addition to the limitation on personal liability provided herein, shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended from time to time. II. INDEMNIFICATION AND INSURANCE SECTION 1. RIGHT TO INDEMNIFICATION. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, -9- 93 criminal, administrative or investigative (hereinafter a Aproceeding"), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was or has agreed to become a director or officer of the Corporation or is or was serving or has agreed to serve at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director or officer, or in any other capacity while serving or having agreed to serve as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said Law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including, without limitation, attorneys' fees, judgments, fines, excise taxes pursuant to the Employee Retirement Income Security Act of 1974 or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to serve in the capacity which initially entitled such person to indemnity hereunder and shall inure to the benefit of his or her heirs, executors and administrators. The right to indemnification conferred in this Part II of this Article Sixth shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred by a current, former or proposed director or officer in his or her capacity as a director or officer or proposed director or officer (and not in any other capacity in which service was or is or has been agreed to be rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such indemnified person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified person is not entitled to be indemnified under this Part II or otherwise. The Corporation may, by action of its board of directors, provide indemnification to employees and agents of the Corporation, individually or as a group, with the same scope and effect as the foregoing indemnification of directors and officers. SECTION 2. RIGHT OF CLAIMANT TO BRING SUIT. If a written claim from or on behalf of an indemnified party under Section 1 of this Part II is not paid in full by the Corporation within thirty days after such written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standard of conduct which makes it permissible under the Delaware General Corporation Law for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its board of directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its board of directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct. -10- 94 SECTION 3. NON-EXCLUSIVITY OF RIGHTS. The right to indemnification and the advancement and payment of expenses conferred in this Part II shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Amended and Restated Certificate of Incorporation, by-law, agreement, vote of stockholders or disinterested directors or otherwise. SECTION 4. INSURANCE. The Corporation may maintain insurance, at its expense, to protect itself and any person who is or was serving as a director, officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law. SECTION 5. SAVINGS CLAUSE. If this Part II or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and hold harmless each director and officer of the Corporation, as to costs, charges and expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Part II that shall not have been invalidated and to the fullest extent permitted by applicable law. SECTION 6. DEFINITIONS. For purposes of this Part II, reference to the "Corporation" shall include, in addition to the Corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger prior to (or, in the case of an entity specifically designated in a resolution of the board of directors, after) the adoption hereof and which, if its separate existence had continued, would have had the power and authority to indemnify its directors, officers and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Part II with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued. SEVENTH: No contract or transaction between the Corporation and one or more of its directors, officers, or stockholders or between the Corporation and any person (as used herein "person" means any corporation, partnership, association, firm, trust, joint venture, political subdivision, or instrumentality) or other organization in which one or more of its directors, officers, or stockholders are directors, officers, or stockholders, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the board or any committee thereof which authorizes the contract or transaction, or solely because his, her, or their votes are counted for such purpose, if: (i) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the board of directors or the committee, and the board of directors or the committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (ii) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or -11- 95 transaction is specifically approved in good faith by majority vote of the stockholders; or (iii) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved, or ratified by the board of directors, a committee thereof, or the stockholders. Interested directors may be counted in determining the presence of a quorum at a meeting of the board of directors or of a committee which authorizes the contract or transaction. EIGHTH: The Corporation reserves the right to amend, change, or repeal any provision contained in the Amended and Restated Certificate of Incorporation in the manner now or hereafter prescribed by law, and all rights and powers conferred herein on stockholders, directors, and officers are subject to this reserved power. -12- 96 EXHIBIT C SUPPORT AGREEMENT THIS SUPPORT AGREEMENT is entered into as of _________, 1997, between National-Oilwell, Inc., a Delaware corporation ("NOI"), and Dreco Energy Services Ltd., an Alberta corporation ("Dreco").

With respect to each NOI Meeting and NOI Consent, the Trustee will mail or cause to be mailed (or otherwise communicate in the same manner as NOI utilizes in communications to holders of NOI Common Stock, subject to the Trustee's ability to provide this method of communication and upon being advised in writing of such method) to each of the Holders named in the List on the same day as the initial mailing or notice (or other communication) with respect thereto is given by NOI to its stockholders: (a) a copy of such notice, together with any proxy or information statement and related materials to be provided to stockholders of NOI; (b) a statement that such Holder is entitled to instruct the Trustee as to the exercise of the Holder Votes with respect to such NOI Meeting or NOI Consent, as the case -6- 113 may be, or, pursuant to Section 4.7 hereof, to attend such NOI Meeting and to exercise personally the Holder Votes thereat; (c) a statement as to the manner in which such instructions may be given to the Trustee, including an express indication that instructions may be given to the Trustee to give: (i) a proxy to such Holder or his designee to exercise personally the Holder Votes; or (ii) a proxy to a designated agent or other representative of the management of NOI to exercise such Holder Votes; (d) a statement that if no such instructions are received from the Holder, the Holder Votes to which such Holder is entitled will not be exercised; (e) a form of direction whereby the Holder may so direct and instruct the Trustee as contemplated herein; and (f) a statement of (i) the time and date by which such instructions must be received by the Trustee in order to be binding upon it, which in the case of a NOI Meeting shall not be earlier than the close of business on the Business Day prior to such meeting, and (ii) the method for revoking or amending such instructions. The materials referred to above are to be provided by NOI to the Trustee, but shall be subject to review and comment by the Trustee. For the purpose of determining Holder Votes to which a Holder is entitled in respect of any such NOI Meeting or NOI Consent, the number of Exchangeable Shares owned of record by the Holder shall be determined at the close of business on the record date established by NOI or by applicable law for purposes of determining stockholders entitled to vote at such NOI Meeting or to give written consent in connection with such NOI Consent. NOI will notify the Trustee in writing of any decision of the board of directors of NOI with respect to the calling of any such NOI Meeting or the seeking of any such NOI Consent and shall provide all necessary information and materials to the Trustee in each case promptly and in any event in sufficient time to enable the Trustee to perform its obligations contemplated by this Section 4.3. 4.4 Copies of Stockholder Information. NOI will deliver to the Trustee copies of all proxy materials, (including notices of NOI Meetings, but excluding proxies to vote shares of NOI Common Stock), information statements, reports (including without limitation all interim and annual financial statements) and other written communications that are to be distributed from time to time to holders of NOI Common Stock in sufficient quantities and in sufficient time so as to enable the Trustee to send those materials to each Holder at the same time as such materials are first sent to holders of NOI Common Stock. The Trustee will mail or otherwise send to each Holder, at the expense of NOI, copies of all such materials -7- 114 (and all materials specifically directed to the Holders or to the Trustee for the benefit of the Holders by NOI) received by the Trustee from NOI at the same time as such materials are first sent to holders of NOI Common Stock. The Trustee will make copies of all such materials available for inspection by any Holder at the Trustee's principal transfer office in the cities of Calgary and Toronto. 4.5 Other Materials. Immediately after receipt by NOI or any stockholder of NOI of any material sent or given generally to the holders of NOI Common Stock by or on behalf of a third party, including without limitation dissident proxy and information circulars (and related information and material) and tender and exchange offer circulars (and related information and material), NOI shall use its best efforts to obtain and deliver to the Trustee copies thereof in sufficient quantities so as to enable the Trustee to forward such material (unless the same has been provided directly to Holders by such third party) to each Holder as soon as possible thereafter. As soon as practicable after receipt thereof, the Trustee will mail or otherwise send to each Holder, at the expense of NOI, copies of all such materials received by the Trustee from NOI. The Trustee will also make copies of all such materials available for inspection by any Holder at the Trustee's principal transfer office in the cities of Calgary and Toronto. 4.6 List of Persons Entitled to Vote. Dreco shall, (i) prior to each annual, general and special NOI Meeting or the seeking of any NOI Consent and (ii) forthwith upon each request made at any time by the Trustee in writing, prepare or cause to be prepared a list (a "List") of the names and addresses of the Holders arranged in alphabetical order and showing the number of Exchangeable Shares held of record by each such Holder, in each case at the close of business on the date specified by the Trustee in such request or, in the case of a List prepared in connection with a NOI Meeting or a NOI Consent, at the close of business on the record date established by NOI or pursuant to applicable law for determining the holders of NOI Common Stock entitled to receive notice of and/or to vote at such NOI Meeting or to give consent in connection with such NOI Consent. Each such List shall be delivered to the Trustee promptly after receipt by Dreco of such request or the record date for such meeting or seeking of consent, as the case may be, and in any event within sufficient time as to enable the Trustee to perform its obligations under this agreement. NOI agrees to give Dreco written notice (with a copy to the Trustee) of the calling of any NOI Meeting or the seeking of any NOI Consent, together with the record dates therefor, sufficiently prior to the date of the calling of such meeting or seeking of such consent so as to enable Dreco to perform its obligations under this Section 4.6. 4.7 Entitlement to Direct Votes. Any Holder named in a List prepared in connection with any NOI Meeting or any NOI Consent will be entitled (i) to instruct the Trustee in the manner described in Section 4.3 hereof with respect to the exercise of the Holder Votes to which such Holder is entitled or (ii) to attend such meeting and personally to exercise thereat (or to exercise with respect to any written consent), as the proxy of the Trustee, the Holder Votes to which such Holder is entitled. -8- 115 4.8 Voting by Trustee, and Attendance of Trustee Representative, at Meeting. (a) In connection with each NOI Meeting and NOI Consent, the Trustee shall exercise, either in person or by proxy, in accordance with the instructions received from a Holder pursuant to Section 4.3 hereof, the Holder Votes as to which such Holder is entitled to direct the vote (or any lesser number thereof as may be set forth in the instructions); provided, however, that such written instructions are received by the Trustee from the Holder prior to the time and date fixed by it for receipt of such instructions in the notice given by the Trustee to the Holder pursuant to Section 4.3 hereof. (b) The Trustee shall cause such representatives as are empowered by it to sign and deliver, on behalf of the Trustee, proxies for Voting Rights to attend each NOI Meeting. Upon submission by a Holder (or its designee) of identification satisfactory to the Trustee's representatives, and at the Holder's request, such representatives shall sign and deliver to such Holder (or its designee) a proxy to exercise personally the Holder Votes as to which such Holder is otherwise entitled hereunder to direct the vote, if such Holder either: (i) has not previously given the Trustee instructions pursuant to Section 4.3 hereof in respect of such meeting, or (ii) submits to the Trustee's representatives written revocation of any such previous instructions. At such meeting, the Holder exercising such Holder Votes shall have the same rights as the Trustee to speak at the meeting in respect of any matter, question or proposition, to vote by way of ballot at the meeting in respect of any matter, question or proposition and to vote at such meeting by way of a show of hands in respect of any matter, question or proposition. 4.9 Distribution of Written Materials. Any written materials to be distributed by the Trustee to the Holders pursuant to this agreement shall be delivered or sent by mail (or otherwise communicated in the same manner as NOI utilizes in communications to holders of NOI Common Stock) to each Holder at its address as shown on the books of Dreco. Dreco shall provide or cause to be provided to the Trustee for this purpose, on a timely basis and without charge or other expense: (a) current lists of the Holders; and (b) on the request of the Trustee, mailing labels to enable the Trustee to carry out its duties under this agreement. The materials referred to above are to be provided by Dreco to the Trustee, but shall be subject to review and comment by the Trustee. -9- 116 4.10 Termination of Voting Rights. Except as otherwise provided herein or in the Exchangeable Share provisions, all of the rights of a Holder with respect to the Holder Votes exercisable in respect of the Exchangeable Shares held by such Holder, including the right to instruct the Trustee as to the voting of or to vote personally such Holder Votes, shall be deemed to be surrendered by the Holder to NOI, and such Holder Votes and the Voting Rights represented thereby shall cease immediately, upon the delivery by such Holder to the Trustee of the certificates representing such Exchangeable Shares in connection with the exercise by the Holder of the Exchange Right or the occurrence of the automatic exchange of Exchangeable Shares for shares of NOI Common Stock, as specified in Article V hereof (unless in either case NOI shall not have delivered the Exchangeable Share Consideration deliverable in exchange therefor to the Trustee for delivery to the Holders), or upon the redemption of Exchangeable Shares pursuant to Article 6 or Article 7 of the Exchangeable Share Provisions, or upon the effective date of the liquidation, dissolution or winding-up of Dreco or any other distribution of the assets of Dreco among its shareholders for the purpose of winding up its affairs pursuant to Article 5 of the Exchangeable Share Provisions, or upon the purchase of Exchangeable Shares from the holder thereof by NOI pursuant to the exercise by NOI of the Retraction Call Right, the Redemption Call Right or the Liquidation Call Right. ARTICLE V EXCHANGE RIGHT AND AUTOMATIC EXCHANGE 5.1 Grant and Ownership of the Exchange Right. NOI hereby grants to the Trustee as trustee for and on behalf of, and for the use and benefit of, the Holders: (a) the Exchange Put Right, (b) the right (the "Exchange Right"), upon the occurrence and during the continuance of an Insolvency Event, to require NOI to purchase from each or any Holder all or any part of the Exchangeable Shares held by the Holders, and (c) the Automatic Exchange Rights, all in accordance with the provisions of this agreement and the Exchangeable Share Provisions, as the case may be. NOI hereby acknowledges receipt from the Trustee as trustee for and on behalf of the Holders of good and valuable consideration (and the adequacy thereof) for the grant of the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights by NOI to the Trustee. During the term of the Trust and subject to the terms and conditions of this agreement, the Trustee shall possess and be vested with full legal ownership of the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights and shall be entitled to exercise all of the rights and powers of an owner with respect to the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights, provided that the Trustee shall: -10- 117 (d) hold the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights and the legal title thereto as trustee solely for the use and benefit of the Holders in accordance with the provisions of this agreement; and (e) except as specifically authorized by this agreement, have no power or authority to exercise or otherwise deal in or with the Exchange Put Right, the Exchange Right or the Automatic Exchange Rights, and the Trustee shall not exercise any such rights for any purpose other than the purposes for which this Trust is created pursuant to this agreement. 5.2 Legended Share Certificates. Dreco will cause each certificate representing Exchangeable Shares to bear an appropriate legend notifying the Holders of: (a) their right to instruct the Trustee with respect to the exercise of the Exchange Put Right and the Exchange Right in respect of the Exchangeable Shares held by a Holder; and (b) the Automatic Exchange Rights. 5.3 General Exercise of Exchange Put Right and Exchange Right. The Exchange Put Right and the Exchange Right shall be and remain vested in and exercised by the Trustee. Subject to Section 7.15 hereof, the Trustee shall exercise the Exchange Put Right and the Exchange Right only on the basis of instructions received pursuant to this Article V from Holders entitled to instruct the Trustee as to the exercise thereof. To the extent that no instructions are received from a Holder with respect to the Exchange Put Right and the Exchange Right, the Trustee shall not exercise or permit the exercise of the Exchange Put Right and the Exchange Right. 5.4 Purchase Price. The purchase price payable by NOI for each Exchangeable Share to be purchased by NOI (a) under the Exchange Put Right shall be the amount determined under the Exchangeable Share Provisions, and (b) under the Exchange Right shall be an amount equal to the Exchangeable Share Price on the last Business Day prior to the day of closing of the purchase and sale of such Exchangeable Share under the Exchange Right. In connection with each exercise of the Exchange Right, NOI will provide to the Trustee an Officer's Certificate setting forth the calculation of the applicable Exchangeable Share Price for each Exchangeable Share. The applicable Exchangeable Share Price for each such Exchangeable Share so purchased may be satisfied only by NOI's issuing and delivering or causing to be delivered to the Trustee, on behalf of the relevant Holder, the applicable Exchangeable Share Consideration representing the total applicable Exchangeable Share Price. 5.5 Exercise Instructions. Subject to the terms and conditions herein set forth, a Holder shall be entitled, upon the occurrence and during the continuance of an Insolvency Event, to instruct the Trustee to exercise the Exchange Right with respect to all or any part of the Exchangeable Shares registered in the name of such Holder on the books of Dreco. -11- 118 To cause the exercise of the Exchange Right by the Trustee, the Holder shall deliver to the Trustee, in person or by certified or registered mail, at its principal transfer office in Calgary, Alberta or at such other places in Canada as the Trustee may from time to time designate by written notice to the Holders, the certificates representing the Exchangeable Shares which such Holder desires NOI to purchase, duly endorsed in blank, and accompanied by such other documents and instruments as may be required to effect a transfer of Exchangeable Shares under the Act and the by-laws of Dreco and such additional documents and instruments as the Trustee may reasonably require, together with: (a) a duly completed form of notice of exercise of the Exchange Right, contained on the reverse of or attached to the Exchangeable Share certificates, stating: (i) that the Holder thereby instructs the Trustee to exercise the Exchange Right so as to require NOI to purchase from the Holder the number of Exchangeable Shares specified therein, (ii) that such Holder has good title to and owns all such Exchangeable Shares to be acquired by NOI free and clear of all liens, claims, encumbrances, security interests and adverse claims or interests, (iii) the names in which the certificates representing NOI Common Stock issuable in connection with the exercise of the Exchange Right are to be issued, and (iv) the names and addresses of the persons to whom the Exchangeable Share Consideration should be delivered; and (b) payment (or evidence satisfactory to the Trustee, Dreco and NOI of payment) of the taxes (if any) payable as contemplated by Section 5.8 of this agreement. If only a part of the Exchangeable Shares represented by any certificate or certificates delivered to the Trustee are to be purchased by NOI under the Exchange Right, a new certificate for the balance of such Exchangeable Shares shall be issued to the Holder at the expense of Dreco. 5.6 Delivery of Exchangeable Share Consideration; Effect of Exercise. Promptly after receipt of the certificates representing the Exchangeable Shares which the Holder desires NOI to purchase under the Exchange Put Right or the Exchange Right (together with such documents and instruments of transfer and a duly completed form of notice of exercise of the Exchange Put Right or the Exchange Right), duly endorsed for transfer to NOI, the Trustee shall notify NOI and Dreco of its receipt of the same, which notice to NOI and Dreco shall constitute exercise of the Exchange Put Right or the Exchange Right by the Trustee on behalf of the Holder of such Exchangeable Shares, and NOI shall immediately thereafter deliver or cause to be delivered to the Trustee, for delivery to the Holder of such Exchangeable Shares (or to such other persons, if any, properly designated by such Holder), the Exchangeable Share Consideration deliverable in connection with the exercise of the -12- 119 Exchange Put Right or the Exchange Right; provided, however, that no such delivery shall be made unless and until the Holder requesting the same shall have paid (or provided evidence satisfactory to the Trustee, Dreco and NOI of the payment of) the taxes (if any) payable as contemplated by Section 5.8 of this agreement. Immediately upon the giving of notice by the Trustee to NOI and Dreco of the exercise of the Exchange Put Right or the Exchange Right, as provided in this Section 5.6, the closing of the transaction of purchase and sale contemplated by the Exchange Put Right or the Exchange Right shall be deemed to have occurred, and the Holder of such Exchangeable Shares shall be deemed to have transferred to NOI all of its right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate, shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive his proportionate part of the total purchase price therefor, unless such Exchangeable Share Consideration is not delivered by NOI to the Trustee, for delivery to such Holder (or to such other persons, if any, properly designated by such Holder), within three Business Days of the date of the giving of such notice by the Trustee, in which case the rights of the Holder shall remain unaffected until such Exchangeable Share Consideration is delivered by NOI and any check included therein is paid. Concurrently with such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of NOI Common Stock delivered to it pursuant to the Exchange Put Right or the Exchange Right. Notwithstanding the foregoing until the Exchangeable Share Consideration is delivered to the Holder, the Holder shall be deemed to still be a holder of the sold Exchangeable Shares for purposes of voting rights with respect thereto under this agreement. 5.7 Exercise of Exchange Right Subsequent to Retraction. In the event that a Holder has exercised its right under Article 6 of the Exchangeable Share Provisions to require Dreco to redeem any or all of the Exchangeable Shares held by the Holder (the "Retracted Shares") and is notified by Dreco pursuant to Section 6.6 of the Exchangeable Share Provisions that Dreco will not be permitted as a result of liquidity or solvency requirements of applicable law to redeem all such Retracted Shares, subject to receipt by the Trustee of written notice to that effect from Dreco and provided that NOI shall not have exercised the Retraction Call Right with respect to the Retracted Shares and that the Holder has not revoked the retraction request delivered by the Holder to Dreco pursuant to Section 6.1 of the Exchangeable Share Provisions, the retraction request will constitute and will be deemed to constitute notice from the Holder to the Trustee instructing the Trustee to exercise the Exchange Right with respect to those Retracted Shares which Dreco is unable to redeem. In any such event, Dreco hereby agrees with the Trustee and in favor of the Holder immediately to notify the Trustee of such prohibition against Dreco's redeeming all of the Retracted Shares and immediately to forward or cause to be forwarded to the Trustee all relevant materials delivered by the Holder to Dreco or to the transfer agent of the Exchangeable Shares (including without limitation a copy of the retraction request delivered pursuant to Section 6.1 of the Exchangeable Share Provisions) in connection with such proposed redemption of the Retracted Shares, and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares which Dreco is not permitted to redeem -13- 120 and will require NOI to purchase such shares in accordance with the provisions of this Article V. 5.8 Stamp or Other Transfer Taxes. Upon any sale of Exchangeable Shares to NOI pursuant to the Exchange Put Right, the Exchange Right or the Automatic Exchange Rights, the share certificate or certificates representing NOI Common Stock to be delivered in connection with the payment of the total purchase price therefor shall be issued in the name of the Holder of the Exchangeable Shares so sold or in such names as such Holder may otherwise direct in writing without charge to the holder of the Exchangeable Shares so sold, provided, however, that such Holder: (a) shall pay (and neither NOI, Dreco nor the Trustee shall be required to pay) any documentary, stamp, transfer or other similar taxes that may be payable in respect of any transfer involved in the issuance or delivery of such shares to a person other than such Holder; or (b) shall have established to the satisfaction of the Trustee, NOI and Dreco that such taxes, if any, have been paid. 5.9 Notice of Insolvency Event. Immediately upon the occurrence of an Insolvency Event or any event which with the giving of notice or the passage of time or both would be an Insolvency Event, Dreco and NOI shall give written notice thereof to the Trustee. As soon as practicable after receiving notice from Dreco or NOI of the occurrence of an Insolvency Event, the Trustee will mail to each Holder, at the expense of NOI, a notice of such Insolvency Event in the form provided by NOI, which notice shall contain a brief statement of the right of the Holders with respect to the Exchange Right. 5.10 Qualification of NOI Common Stock. NOI covenants that if any shares of NOI Common Stock to be issued and delivered pursuant to the Exchange Put Right, the Exchange Right or the Automatic Exchange Rights require registration or qualification with or approval of or the filing of any document including any prospectus or similar document, the taking of any proceeding with or the obtaining of any order, ruling or consent from any governmental or regulatory authority under any Canadian or United States federal, provincial or state law or regulation or pursuant to the rules and regulations of any regulatory authority, or the fulfillment of any other legal requirement (collectively, the "Applicable Laws") before such shares may be issued and delivered by NOI to the initial holder thereof (other than Dreco) or in order that such shares may be freely traded thereafter (other than any restrictions on transfer by reason of a holder being a "control person" of NOI for purposes of Canadian federal or provincial securities law or an "affiliate" of NOI for purposes of United States federal or state securities law), NOI will in good faith expeditiously take all such actions and do all such things as are necessary to cause such shares of NOI Common Stock to be and remain duly registered, qualified or approved. NOI represents and warrants that it has in good faith taken all actions and done all things as are necessary under Applicable Laws as they exist on the date hereof to cause the shares of NOI Common Stock to be issued and delivered pursuant to the Exchange Put Right, the Exchange -14- 121 Right and the Automatic Exchange Rights and to be freely tradeable thereafter (other than restrictions on transfer by reason of a holder being a "control person" of NOI for the purposes of Canadian federal and provincial securities law or an "affiliate" of NOI for the purposes of United States federal or state securities law). NOI will in good faith expeditiously take all such actions and do all such things as are necessary to cause all shares of NOI Common Stock to be delivered pursuant to the Exchange Put Right, the Exchange Right or the Automatic Exchange Rights to be listed, quoted or posted for trading on all stock exchanges and quotation systems on which such shares are listed, quoted or posted for trading at such time. 5.11 Reservation of Shares of NOI Common Stock. NOI hereby represents, warrants and covenants that it has irrevocably reserved for issuance and will at all times keep available, free from pre-emptive and other rights, out of its authorized and unissued capital stock such number of shares of NOI Common Stock: (a) as is equal to the sum of (i) the number of Exchangeable Shares issued and outstanding from time to time and (ii) the number of Exchangeable Shares issuable upon the exercise of all rights to acquire Exchangeable Shares outstanding from time to time and (b) as are now and may hereafter be required to enable and permit Dreco to meet its obligations hereunder, under the Amended and Restated Certificate of Incorporation of NOI, under the Support Agreement, under the Exchangeable Share Provisions and under any other security or commitment pursuant to the Arrangement with respect to which NOI may now or hereafter be required to issue shares of NOI Common Stock. 5.12 Automatic Exchange on Liquidation of NOI. (a) NOI will give the Trustee written notice of each of the following events at the time set forth below: (i) in the event of any determination by the board of directors of the NOI to institute voluntary liquidation, dissolution or winding-up proceedings with respect to NOI or to effect any other distribution of assets of NOI among its stockholders for the purpose of winding up its affairs, at least 60 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; and (ii) immediately, upon the earlier of (A) receipt by NOI of notice of and -15- 122 (B) NOI's otherwise becoming aware of any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of NOI or to effect any other distribution of assets of NOI among its stockholders for the purpose of winding up its affairs. (b) Immediately following receipt by the Trustee from NOI of notice of any event (a "Liquidation Event") contemplated by Section 5.12(a) above, the Trustee will give notice thereof to the Holders. Such notice will be provided by NOI to the Trustee and shall include a brief description of the automatic exchange of Exchangeable Shares for shares of NOI Common Stock provided for in Section 5.12(c) below. (c) In order that the Holders will be able to participate on a pro rata basis with the holders of NOI Common Stock in the distribution of assets of NOI in connection with a Liquidation Event, immediately prior to the effective time (the "Liquidation Event Effective Time") of a Liquidation Event, all of the then outstanding Exchangeable Shares shall be automatically exchanged for shares of NOI Common Stock. To effect such automatic exchange, NOI shall be deemed to have purchased each Exchangeable Share outstanding immediately prior to the Liquidation Event Effective Time and held by Holders, and each Holder shall be deemed to have sold the Exchangeable Shares held by it at such time, for a purchase price per share equal to the Exchangeable Share Price applicable at such time. In connection with such automatic exchange, NOI will provide to the Trustee an Officer's Certificate setting forth the calculation of the purchase price for each Exchangeable Share. (d) The closing of the transaction of purchase and sale contemplated by Section 5.12(c) above shall be deemed to have occurred immediately prior to the Liquidation Event Effective Time, and each Holder of Exchangeable Shares shall be deemed to have transferred to NOI all of the Holder's right, title and interest in and to such Exchangeable Shares and the related interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares, and NOI shall deliver to the Holder the Exchangeable Share Consideration deliverable upon the automatic exchange of Exchangeable Shares. Concurrently with such Holder's ceasing to be a holder of Exchangeable Shares, the Holder shall be considered and deemed for all purposes to be the holder of the shares of NOI Common Stock issued to it pursuant to the automatic exchange of Exchangeable Shares for NOI Common Stock, and the certificates held by the Holder previously representing the Exchangeable Shares exchanged by the Holder with NOI pursuant to such automatic exchange shall thereafter be deemed to represent the shares of NOI Common Stock issued to the Holder by NOI pursuant to such automatic exchange. Upon the request of a Holder and the surrender by the Holder of Exchangeable Share certificates deemed to represent shares of NOI Common Stock, duly endorsed in blank and accompanied by such instruments of transfer as NOI may reasonably require, NOI shall deliver or cause to be delivered to the Holder certificates representing the shares of NOI Common Stock of which the Holder is the holder. Notwithstanding the foregoing, until each Holder is actually entered on the register of holders of NOI Common Stock, such Holder shall be deemed to still be a holder of the -16- 123 transferred Exchangeable Shares for purposes of all voting rights with respect thereto under this agreement. ARTICLE VI RESTRICTIONS ON ISSUANCE OF NOI SPECIAL VOTING STOCK During the term of this agreement, NOI will not issue any shares of NOI Special Voting Stock in addition to the Voting Share. ARTICLE VII CONCERNING THE TRUSTEE 7.1 Powers and Duties of the Trustee. The rights, powers and authorities of the Trustee under this agreement, in its capacity as trustee of the Trust, shall include: (a) receipt and deposit of the Voting Share from NOI as trustee for and on behalf of the Holders in accordance with the provisions of this agreement; (b) granting proxies and distributing materials to Holders as provided in this agreement; (c) voting the Holder Votes in accordance with the provisions of this agreement; (d) receiving the grant of the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights from NOI as trustee for and on behalf of the Holders in accordance with the provisions of this agreement; (e) exercising the Exchange Put Right and the Exchange Right and enforcing the benefit of the Automatic Exchange Rights, in each case in accordance with the provisions of this agreement, and in connection therewith receiving from Holders Exchangeable Shares and other requisite documents and distributing to such Holders the shares of NOI Common Stock and checks, if any, to which such Holders are entitled upon the exercise of the Exchange Put Right and the Exchange Right or pursuant to the Automatic Exchange Rights, as the case may be; (f) holding title to the Trust Estate; (g) investing any moneys forming, from time to time, a part of the Trust Estate as provided in this agreement; (h) taking action at the direction of a Holder or Holders to enforce the obligations of NOI under this agreement; and -17- 124 (i) taking such other actions and doing such other things as are specifically provided in this agreement. In the exercise of such rights, powers and authorities the Trustee shall have (and is granted) such incidental and additional rights, powers and authority not in conflict with any of the provisions of this agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers and authorities by the Trustee shall be final, conclusive and binding upon all persons. For greater certainty, the Trustee shall have only those duties as are set out specifically in this agreement. The Trustee in exercising its rights, powers, duties and authorities hereunder shall act honestly and in good faith with a view to the best interests of the Holders and shall exercise the care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances. The Trustee shall not be bound to give any notice or do or take any act, action or proceeding by virtue of the powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof; nor shall the Trustee be required to take any notice of, or to do or to take any act, action or proceeding as a result of any default or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notices shall distinctly specify the default or breach desired to be brought to the attention of the Trustee and in the absence of such notice the Trustee may for all purposes of this agreement conclusively assume that no default or breach has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein. 7.2 No Conflict of Interest. The Trustee represents to Dreco and NOI that at the date of execution and delivery of this agreement there exists no material conflict of interest in the role of the Trustee as a fiduciary hereunder and the role of the Trustee in any other capacity. The Trustee shall, within 90 days after it becomes aware that such a material conflict of interest exists, either eliminate such material conflict of interest or resign in the manner and with the effect specified in Article X hereof. If, notwithstanding the foregoing provisions of this Section 7.2, the Trustee has such a material conflict of interest, the validity and enforceability of this agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Trustee contravenes the foregoing provisions of this Section 7.2, any interested party may apply to the superior court of the province in which Dreco has its registered office for an order that the Trustee be replaced as trustee hereunder. 7.3 Dealings with Transfer Agents, Registrars, Etc. Dreco and NOI irrevocably authorize the Trustee, from time to time, to: (a) consult, communicate and otherwise deal with the respective registrars and transfer agents, and with any such subsequent registrar or transfer agent, of the Exchangeable Shares and NOI Common Stock; and (b) requisition, from time to time, -18- 125 (i) from any such registrar or transfer agent any information readily available from the records maintained by it which the Trustee may reasonably require for the discharge of its duties and responsibilities under this agreement and (ii) from the transfer agent of NOI Common Stock, and any subsequent transfer agent of such shares, to complete the exercise from time to time of the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights in the manner specified in Article V hereof, the share certificates issuable upon such exercise. Dreco and NOI irrevocably authorize their respective registrars and transfer agents to comply with all such requests. NOI covenants that it will supply its transfer agent with duly executed share certificates for the purpose of completing the exercise from time to time of the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights, in each case pursuant to Article V hereof. 7.4 Books and Records. The Trustee shall keep available for inspection by NOI and Dreco, at the Trustee's principal transfer office in Calgary, Alberta, correct and complete books and records of account relating to the Trustee's actions under this agreement, including without limitation all information relating to mailings and instructions to and from Holders and all transactions pursuant to the Voting Rights, the Exchange Put Right, the Exchange Right and the Automatic Exchange Rights for the term of this agreement. On or before March 31, 1998, and on or before March 31 in every year thereafter, so long as the Voting Share is on deposit with the Trustee, the Trustee shall transmit to NOI and Dreco a brief report, dated as of the preceding December 31, with respect to: (a) property and funds comprising the Trust Estate as of that date; (b) the number of exercises of the Exchange Put Right and the Exchange Right, if any, and the aggregate number of Exchangeable Shares received by the Trustee on behalf of Holders in consideration of the issue and delivery by NOI of shares of NOI Common Stock in connection with the Exchange Put Right and the Exchange Right, during the calendar year ended on such date; and (c) all other actions taken by the Trustee in the performance of its duties under this agreement which it had not previously reported. 7.5 Income Tax Returns and Reports.

ARTICLE IX INDEMNIFICATION AND LIMITATION OF LIABILITY 9.1 Indemnification of the Trustee. NOI and Dreco jointly and severally agree to indemnify and hold harmless the Trustee and each of its directors, officers, employees and agents appointed and acting in accordance with this agreement (collectively, the "Indemnified Parties") against all claims, losses, damages, costs, penalties, fines and reasonable expenses (including reasonable expenses of the Trustee's legal counsel) which, without fraud, negligence, willful misconduct or bad faith on the part of such Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason of or as a result of the Trustee's acceptance or administration of the Trust, its compliance with its duties set forth in this agreement, or any written or oral instructions delivered to the Trustee by NOI or Dreco pursuant hereto. In no case shall NOI or Dreco be liable under this indemnity for any claim against any of the Indemnified Parties unless NOI and Dreco shall be notified by the Trustee of the written assertion of a claim or of any action commenced against the Indemnified Parties, promptly after any of the Indemnified Parties shall have received any such written assertion of a claim or shall have been served with a summons or other first legal process giving information as to the nature and basis of the claim. Subject to (i) below, NOI and Dreco shall be entitled to participate at their own expense in the defense and, if NOI or Dreco so elect at any time after receipt of such notice, either of them may assume the defense of any suit brought to enforce any such claim. The Trustee shall have the right to employ separate counsel in any such suit and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Trustee unless: (i) the employment of such counsel has been authorized by NOI or Dreco, such authorization not to be unreasonably withheld; or (ii) the named parties to any such suit include both the Trustee and NOI or Dreco and the Trustee shall have been advised by counsel acceptable to NOI or Dreco that there may be one or more legal defenses available to the Trustee that are different from or in addition to those available to NOI or Dreco and that an actual or potential conflict of interest exists (in which case NOI and Dreco shall not have the right to assume the defense of such suit on behalf of the Trustee, but shall be liable to pay the reasonable fees and expenses of counsel for the Trustee). 9.2 Limitation of Liability. The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any part of the Trust Estate or any loss incurred on any investment of funds pursuant to this agreement, except to the extent that such loss is attributable to the fraud, negligence, willful misconduct or bad faith on the part of the Trustee. -24- 131 ARTICLE X CHANGE OF TRUSTEE 10.1 Resignation.

However, on the written request of NOI and Dreco or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of this agreement, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee, NOI, Dreco and such predecessor trustee shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. 10.4 Notice of Successor Trustee.

FOR IMMEDIATE RELEASE


                      NATIONAL-OILWELL AND DRECO ANNOUNCE
                  SIGNING OF DEFINITIVE COMBINATION AGREEMENT


HOUSTON, TX, MAY 14, 1997 - - National-Oilwell, Inc. (NOI/NYSE) and Dreco
Energy Services Ltd. (NASDAQ/DREAF, T.S.E./DRE.A) jointly announced today the
signing of a definitive agreement to combine the two companies.

The terms of the agreement provide for the exchange of Dreco common shares for
National-Oilwell common shares in a pooling of interests transaction that is
expected to be tax free to both companies.  The exchange ratio is subject to a
collar and will provide Dreco's shareholders with 1.2 shares of National-
Oilwell stock, if during the 20 consecutive trading days ending 5 days before
closing, National-Oilwell's average stock price is between $36.00 and $47.25.
If the average stock price is above $47.25, the exchange ratio adjusts to
provide Dreco holders with $56.70 of National-Oilwell common stock, and, if the
average stock price is below $36.00, the exchange ratio adjusts to provide
Dreco holders with $43.20 of National-Oilwell common stock.

National-Oilwell would issue approximately 9.4 million shares of its common
stock valued at $366 million, based on a 1.2 exchange ratio.  The combination
is expected to be accretive to estimated 1997 earnings per share of National-
Oilwell, excluding one-time charges related to expenses associated with the
transaction.

Joel V. Staff, Chairman and CEO of National-Oilwell, said, "The combination of
National-Oilwell and Dreco affords excellent opportunities for the
shareholders, employees and customers of both companies by significantly
enhancing the combined company's ability to provide high quality equipment and
services.  Bringing together the respective strengths of these organizations
will create a unique capability to provide our customers with innovative and
reliable drilling systems solutions.  In addition, the combination of Dreco's




                                   -more-
   2
downhole products group, including its role as a leading independent supplier
of drilling motors, with National-Oilwell's distribution services presents
numerous opportunities to expand the already strong positions held by the
respective companies.  The combined companies will have a strong balance sheet
and a current market capitalization in excess of $1 billion."

Fred Pheasey, Chairman of Dreco, said, "The range of products of the combined
drilling and well servicing equipment businesses will span from equipment and
packages for deep drilling requirements through to reentry drilling, well
servicing and coiled tubing well service and drilling applications, both land
and offshore.  In addition, Dreco's downhole product business will benefit from
its tie with National-Oilwell."  Robert L. Phillips, President and CEO of
Dreco, further added "This transaction provides an exciting opportunity for
Dreco's shareholders and employees.  It is consistent with the company's longer
term strategic goals.  The combination will create an organization that has
greater prospects for broad based growth in all of our businesses.  In
particular, National-Oilwell's complementary products and distribution system
in addition to its worldwide installed base of equipment should provide
significant opportunities.  Both companies  have key customer relationships
which should be enhanced by this combination.

At closing, the shareholders of Dreco would have the option of receiving either
National-Oilwell common stock or Dreco exchangeable shares.  In general, the
exchangeable shares would be exchangeable at the shareholder's option for
National-Oilwell common stock on a share-for-share basis and otherwise would
have equivalent economic and voting rights.

The merger has been approved by the boards of directors of both companies.
Credit Suisse First Boston acted as financial advisor to Dreco, and Merrill
Lynch & Co. acted as financial advisor to National-Oilwell.  Holders of
approximately 52% of National-Oilwell's common stock, as well as the Chairman
and the President and CEO of Dreco, have entered into voting agreements in
support of the transaction.

The transaction, which is structured as a plan of arrangement under Alberta
law, is subject to various conditions, including shareholder approvals of both
companies, the approval of the Alberta Court, and other regulatory approvals in
both the U.S. and Canada.  It is anticipated that shareholders meetings and the
closing of the transaction would occur during the third quarter of 1997.

National-Oilwell is a worldwide leader in the design, manufacture and sale of
machinery and equipment and in the distribution of maintenance, repair and
operating products used in oil and gas drilling and production.  The company's
machinery and equipment include drawworks, mud pumps and power swivels, which
are the major mechanical components of rigs used to drill oil and gas wells.
Many of these components are designed specifically for applications in
offshore, extended reach and deep land drilling.  The Company distributes
products and provides services, including complete customer inventory
procurement and management, from a network of approximately 120 service centers
and from its Houston headquarters.

Dreco, based in Edmonton, Alberta, Canada, designs and manufactures specialty
drilling and well servicing equipment and downhole tools.  Drilling and well
servicing equipment packages include those specialized for Arctic operating
environments, offshore platforms, desert service as well as conventional land
and offshore applications.  Downhole tools include highly engineered drilling
products focused on the increased use of horizontal and other directional
drilling applications by oil and gas companies.

Statements made in this press release that are forward-looking in nature are
intended to be "forward-looking statements" with the meaning of Section 21E of
the Securities Exchange Act of 1934.  Although National-Oilwell and Dreco
believe that the expectations described herein are reasonable, the actual
results of the combined company 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, and delays in the
ability of National-Oilwell to fully integrate the operations of Dreco and
achieve the strategic benefits described above.  Other factors are set forth
under "Risk Factors" in Item 1 of National-Oilwells's Annual Report on Form 10-
K for the fiscal year ended December 31, 1996, filed with the Securities and
Exchange Commission, and under "Industry Conditions," "International
Operations," "Significant Contracts," "Operating Risks" and "Environmental
Matters" in Item 1 of Dreco's Annual Report on Form 10-K for the fiscal year
ended August 31, 1996, filed with the Securities and Exchange Commission.
