During the last five years, none of the Reporting Persons nor any executive officer or director of First Reserve has (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding or a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. On August 12, 1994 Total Energy Services Company ("Total") merged with and into ET Merger Corporation ("ET"), a wholly owned subsidiary of Enterra Corporation ("Enterra") pursuant to an Agreement and Plan of Merger among Total, Enterra and ET dated as of May 2, 1994, as amended by the First Amendment to Agreement and Plan of Merger dated as of July 15, 1994 (the "Enterra Merger Agreement") (the "Enterra Merger"). Prior to the 14 14 Enterra Merger, the Funds beneficially owned approximately 99.2% of the outstanding shares of common stock of Total, par value $.01 per share ("Total Stock"). Total continued as a wholly-owned subsidiary of Enterra, and each share of Total Stock was converted into approximately 169.3 shares of Enterra common stock, par value $1.00 per share (the "Enterra Shares") (although cash was paid in lieu of fractional Enterra Shares), such that each Fund owned the following numbers of Enterra Shares: (i) Fund I owned 1,993,529 Enterra Shares, as a result of the conversion of 11,774.68 shares of Total Stock; (ii) Fund II owned 1,233,907 Enterra Shares, as a result of the conversion of 7,288.01 shares of Total Stock; (iii) Fund III owned 597,408 Enterra Shares, as a result of the conversion of 3,687.97 Enterra Shares of Total Stock and of the grant of the right to receive 26,989 Enterra Shares to Fund VI in exchange for cash; (iv) Fund IV owned 2,323,562 Enterra Shares, as a result of the conversion of 14,343.54 shares of Total Stock and of the grant of the right to receive 104,892.0 Enterra Shares to Fund VI for cash; (v) Fund V owned 3,355,254 Shares, as a result of the conversion of 19,817.64 shares of Total Stock; (vi) Fund V-2 owned 838,427.0 Enterra Shares, resulting from the conversion of 4,952.13 shares of Total Stock; and (vii) Fund VI owned 870,262 Enterra Shares, as a result of the conversion of 4,349.72 shares of Total Stock and of the receipt of the right to receive 133,827 Enterra Shares, in the aggregate, from Fund III, Fund IV and Gerald Hage in exchange for cash. 15 15 On October 5, 1995, Enterra merged with and into Weatherford, pursuant to an Agreement and Plan of Merger, dated as of June 23, 1995, as amended as of August 28, 1995 (the "Weatherford Merger Agreement") (the "Weatherford Merger"). Weatherford continued as the surviving corporation and changed its name to Weatherford Enterra, Inc. Pursuant to the Weatherford Merger, each Enterra Share was converted into the right to receive 1.69 Weatherford Shares, before giving effect to a one-for-two reverse stock split (the "Reverse Stock Split") of Weatherford Shares. After giving effect to the Reverse Stock Split as of the Effective Time (as defined in the Weatherford Merger Agreement), each Enterra Share was converted into the right to receive 0.845 of a Weatherford Share (although cash was paid in lieu of fractional Shares). Following the Reverse Stock Split, each Fund owned the following numbers of Weatherford Shares: (i) Fund I owned 1,684,532 Weatherford Shares, as a result of the conversion of 1,993,529 Enterra Shares; (ii) Fund II owned 1,042,651 Weatherford Shares, as a result of the conversion of 1,233,907 Enterra Shares; (iii) Fund III owned 504,809 Weatherford Shares, as a result of the conversion of 597,408 Enterra Shares; (iv) Fund IV owned 1,963,409 Weatherford Shares, the conversion of 2,323,562 Enterra Shares; (v) Fund V owned 2,835,189 Weatherford Shares, as a result of the conversion of 3,355,254 Enterra Shares; (vi) Fund V-2 owned 708,470 Weatherford Shares, as a result of the conversion of 838,427.0 Enterra Shares; and (vii) Fund VI owned 735,371 Weatherford Shares, as a result of the conversion of 870,262 Enterra Shares. 16 16 The source of consideration used by the Funds in acquiring the Weatherford Shares reported as beneficially owned in Item 5 hereof was 11,212,349 Enterra Shares. The 11,212,349 Enterra Shares used by the Funds to obtain their 9,474,431 Weatherford Shares, were acquired with 66,213.69 shares of Total Stock, and in the case of Fund VI only, also working capital. The 66,213.69 shares of Total Stock used by the Funds to obtain their 11,212,349 Enterra Shares were acquired with the assets of the Fund. ITEM 4. PURPOSE OF TRANSACTION. The Funds acquired the Weatherford Shares disclosed in Item 5 of this Schedule 13D in order to continue their substantial investment position in the entity surviving the Weatherford Merger. During the term of the Stockholders' Agreement dated as of June 23, 1995, as amended, between Weatherford and the Funds (the "Weatherford Stockholders' Agreement") attached as Exhibit C, two of four designated Funds will be permitted to designate two members for nomination to the Weatherford Board of Directors, provided the Funds own Weatherford Shares in certain minimum amounts. The Funds intend to participate in and influence the affairs of Weatherford through their two designees on the Board of Directors. The Funds are contractually prohibited from taking certain actions with respect to the Weatherford Shares during the term of the Weatherford Stockholders' Agreement as further described in Item 6 of this Schedule 13D. 17 17 Except as described above, at the present time the Reporting Persons do not have any plans or proposals that would relate to any transaction, change or event specified in clauses (a) through (j) of Item 4 of the Schedule 13D form.

The corporate name of the Surviving Corporation shall be "Weatherford Enterra, Inc.". 1.2 Closing Date. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Fulbright & Jaworski L.L.P., 1301 McKinney, Suite 5100, Houston, Texas as soon as practicable after the satisfaction or waiver of the conditions set forth in Article VI or at such other time and place and on such other date as Weatherford and Enterra shall agree; provided, that the closing -1- 6 conditions set forth in Article VI shall have been satisfied or waived at or prior to such time. The date on which the Closing occurs is herein referred to as the "Closing Date". 1.3 Consummation of the Merger. As soon as practicable on the Closing Date, the parties hereto will cause the Merger to be consummated by filing with the Secretary of State of the State of Delaware a certificate of merger in such form as required by, and executed in accordance with, the relevant provisions of the DGCL. The "Effective Time" of the Merger as that term is used in this Agreement shall mean the effective time set forth in the certified copy of the certificate of merger issued by the Secretary of State of the State of Delaware with respect to the Merger. 1.4 Effects of the Merger. The Merger shall have the effects set forth in the applicable provisions of the DGCL. 1.5 Certificate of Incorporation; Bylaws. The Restated Certificate of Incorporation and bylaws of Weatherford, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation and bylaws of the Surviving Corporation and thereafter shall continue to be its Certificate of Incorporation and bylaws until amended as provided therein and under the DGCL. 1.6 Directors and Officers. (a) The Board of Directors of the Surviving Corporation shall consist of ten persons. Exhibit 1.6(a) sets forth the initial directors of the Surviving Corporation, along with the term of office for, and the committee or committees of the Board of Directors, if any, on, which each such director shall serve. (b) Exhibit 1.6(b) sets forth the initial officers of the Surviving Corporation, each of whom shall hold office until his or her successor is duly elected or appointed and qualified. 1.7 Conversion of Securities; Exchange Fractional Shares. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Weatherford, Enterra or their stockholders: (a) Each share of Enterra Common Stock issued and outstanding immediately prior to the Effective Time (the "Shares"), other than any Shares to be canceled pursuant to Section 1.7(b), shall be converted, subject to the provisions of this Section 1.7, into the right to receive 0.845 of a share (which number reflects a 1 for 2 reverse stock split to be effected at the Closing) of Weatherford Common Stock (the "Conversion Rate"); provided, however, that no fractional shares of Weatherford Common Stock shall be issued, and, in lieu thereof, a cash payment shall be made pursuant to Section 1.7(f) hereof. (b) Each share of Enterra Common Stock held in the treasury of Enterra and each Share owned by Weatherford or any direct or indirect wholly-owned subsidiary of Enterra or of Weatherford immediately prior to the -2- 7 Effective Time shall be canceled and extinguished at the Effective Time without any conversion thereof and no payment shall be made with respect thereto. (c) As soon as practicable after the Effective Time, each holder of an outstanding certificate that prior thereto represented Shares shall be entitled, upon surrender thereof to the transfer agent for the Weatherford Common Stock, to receive in exchange therefor a certificate or certificates representing the number of whole shares of Weatherford Common Stock into which the Shares so surrendered shall have been converted as aforesaid, of such denominations and registered in such names as such holder may request. Each holder of Shares who would otherwise be entitled to a fraction of a share of Weatherford Common Stock shall, upon surrender of the certificates representing Shares held by such holder to Weatherford's transfer agent, be paid an amount in cash in accordance with the provisions of Section 1.7(f). Until so surrendered, each outstanding certificate that, prior to the Effective Time, represented Shares shall be deemed from and after the Effective Time, for all corporate purposes, other than the payment of earlier dividends and distributions, to evidence the ownership of the number of full shares of Weatherford Common Stock into which such Shares shall have been converted pursuant to this Section 1.7. Unless and until any such outstanding certificates shall be surrendered, no dividends or other distributions payable to the holders of Weatherford Common Stock, as of any time on or after the Effective Time, shall be paid to the holders of such outstanding certificates that prior to the Effective Time represented Shares; provided, however, that, upon surrender and exchange of such outstanding certificates, there shall be paid to the record holders of the certificates issued and exchanged therefor the amount, without interest thereon, of dividends and other distributions, if any, that theretofore were declared and became payable since the Effective Time with respect to the number of full shares of Weatherford Common Stock issued to such holders. (d) All shares of Weatherford Common Stock into which the Shares shall have been converted pursuant to this Section 1.7 shall be issued in full satisfaction of all rights pertaining to such converted Shares. (e) If any certificate for shares of Weatherford Common Stock is to be issued in a name other than that in which the certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange shall have paid to Weatherford or its transfer agent any transfer or other taxes required by reason of the issuance of a certificate for shares of Weatherford Common Stock in any name other than that of the registered holder of the certificate surrendered, or established to the satisfaction of Weatherford or its transfer agent that such tax has been paid or is not payable. (f) No fraction of a share of Weatherford Common Stock shall be issued, but in lieu thereof each holder of Shares who would otherwise be entitled to a fraction of a share of Weatherford Common Stock shall, upon surrender of -3- 8 the Shares held by such holder to Weatherford's transfer agent, be paid an amount in cash equal to the value of such fraction of a share based upon the closing price of Weatherford Common Stock on the New York Stock Exchange on the last trading day prior to the Effective Time. No interest shall be paid on such amount. All Shares held by a record holder other than nominee holders shall be aggregated for purposes of computing the number of shares of Weatherford Common Stock to be issued pursuant to this Section 1.7.

(i) Employee Benefit Plans. The Weatherford Disclosure Letter sets forth a complete and accurate list of: (i) each "employee welfare benefit plan" (as such term is defined in Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) (the "Weatherford Welfare Plans"); (ii) each "employee pension benefit plan" (as such term is defined in Section 3(2) of ERISA) (the "Weatherford Pension Plans"); and (iii) all other employee benefit agreements or arrangements, including, without limitation, deferred compensation plans, incentive plans, bonus plans or arrangements, stock option plans, stock purchase plans, golden parachute agreements, severance pay plans, dependent care plans, cafeteria plans, employee assistance programs, scholarship programs, employment contracts and other similar plans, agreements and arrangements (collectively, with the Weatherford Welfare Plans and the Weatherford Pension Plans, the "Weatherford Benefit Plans"), that are currently in effect or were maintained within three years of the Closing Date, or have been approved before this date but are not yet effective, for the benefit of directors, officers, employees or former employees (or their beneficiaries) of Weatherford, any of the Weatherford Subsidiaries incorporated in the United States (the "Weatherford U.S. Subsidiaries") or any member of a controlled group or affiliated service group (as defined in Section 414(b), (c), (m) or (o) of the Code) that is incorporated or domiciled in the United States of -10- 15 which Weatherford or any of the Weatherford U.S. Subsidiaries is a member (collectively, the "Weatherford Group"). Weatherford and the Weatherford U.S. Subsidiaries will provide to Enterra, as to each Weatherford Benefit Plan, as applicable, access to a complete and accurate copy of (i) such plan, agreement or arrangement; (ii) the trust, group annuity contract or other document that provides the funding for such plan; (iii) the most recent annual Form 5500, 990 and 1041 reports; (iv) the most recent actuarial report or valuation statement; (v) the most current summary plan description, handbook or other booklet that describes any Weatherford Benefit Plan, and any summary of material modifications prepared after each such summary plan description; (vi) the most recent Internal Revenue Service ("IRS") determination letter and all rulings or determinations requested from the IRS subsequent to the date of such determination letter; and (vii) all other pending correspondence from the IRS or the Department of Labor received by any member of the Weatherford Group that relates to such plan. Each Weatherford Welfare Plan and Weatherford Pension Plan (i) is in compliance with ERISA, including, without limitation, all reporting and disclosure requirements of Part 1 of Subtitle B of Title I of ERISA, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect; (ii) is in compliance with the Code, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect; (iii) has had the appropriate Form 5500 timely filed for any Weatherford Pension Plan, if applicable, for each year of its existence and for any Weatherford Welfare Plan for each year of its existence after 1987, except where the failure to cause such timely filing would not, either individually or in the aggregate, have a Material Adverse Effect; (iv) has not engaged in any transaction described in Section 406 or 407 of ERISA or Section 4975 of the Code unless it received or is entitled to an exemption under Section 408 of ERISA or Section 4975 of the Code, as applicable, or unless such transaction has been corrected and all applicable excise taxes paid or waived; (v) has no issue pending (other than the payment of benefits in the normal course or the qualification of the plan pursuant to an application pending before the IRS) nor any issue resolved adversely to the Weatherford Group that, in either case, may subject the Weatherford Group to the payment of a penalty, interest, tax or other amount, which, either individually or in the aggregate, would have a Material Adverse Effect; and (vi) can be unilaterally terminated or amended on no more than 90 days notice. No notice has been received by the Weatherford Group of an increase or proposed increase in any premium relative to any Weatherford Benefit Plan, and no amendment to any Weatherford Benefit Plan within the last twelve months has increased the rate of employer contributions thereunder that, either individually or in the aggregate, would have a Material Adverse Effect. Each Weatherford Benefit Plan that is intended to be a voluntary employee benefit association has been submitted to and approved by the IRS as exempt from federal income tax under Section 501(c)(9) of the Code or the applicable submission period relating to any such plan will not have ended prior -11- 16 to the Closing. No Weatherford Benefit Plan will cause the Weatherford Group to have liability for severance pay as a result of this Agreement. The Weatherford Group does not provide employee post-retirement medical or health coverage or contribute to or maintain any employee welfare benefit plan that provides for health benefit coverage following termination of employment except as required by Section 4980B(f) of the Code or other applicable statute, nor has the Weatherford Group made any representations, agreements, covenants or commitments to provide that coverage. Except for each Weatherford Pension Plan that is an ERISA top- hat plan, each Weatherford Pension Plan has been submitted to and approved as qualifying under Section 401(a) of the Code by the IRS or the applicable remedial amendment period relating to such plan will not have ended prior to the Closing. To the knowledge of Weatherford, no facts have occurred that, if known by the IRS, could cause disqualification of any Weatherford Pension Plan. Each Weatherford Pension Plan to which Section 412 of the Code is applicable fully complies with the funding requirements of that Section and there is no accumulated funding deficiency as defined in Section 302(a)(2) of ERISA (whether or not waived) in any such plan. The Weatherford Group has paid all premiums (including, without limitation, interest, charges and penalties for late payment) due the Pension Benefit Guaranty Corporation (the "PBGC") with respect to each Weatherford Pension Plan for which premiums are required. No Weatherford Pension Plan has been terminated under circumstances that would result in liability to the PBGC or the Weatherford Group. There has been no "reportable event" (as defined in Section 4043(b) of ERISA and the regulations under that Section) with respect to any Weatherford Pension Plan subject to Title IV of ERISA. With respect to each Weatherford Pension Plan subject to Title IV of ERISA, the Weatherford Group has not (i) ceased operations at a facility so as to become subject to the provisions of Section 4062(e) of ERISA, (ii) withdrawn as a substantial employer so as to become subject to the provisions of Section 4063 of ERISA or (iii) ceased making contributions on or before the Closing Date to any such plan subject to Section 4064(a) of ERISA to which the Weatherford Group made contributions at any time during the six years prior to the Closing Date. Neither the Weatherford Group nor any member thereof has made a complete or partial withdrawal from a multiemployer plan (as defined in Section 3(37) of ERISA) so as to incur withdrawal liability as defined in Section 4201 of ERISA. Weatherford's subsidiaries incorporated outside of the United States and any benefit plans maintained by any of them for the benefit of their directors, officers, employees or former employees (or any of their beneficiaries) are in compliance with applicable laws pertaining to such plans in the jurisdictions of such subsidiaries, except where such failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect. (j) Taxes. All returns and reports, including, without limitation, information and withholding returns and reports ("Tax Returns") of or relating to any foreign, federal, state or local tax, assessment or other governmental -12- 17 charge ("Taxes" or a "Tax") that are required to be filed on or before the Closing Date by or with respect to Weatherford or any of the Weatherford Subsidiaries have been or will be duly and timely filed, and all Taxes, including, without limitation, interest and penalties, due and payable pursuant to such Tax Returns have been paid or adequately provided for in reserves established by Weatherford, except where the failure to file, pay or provide for would not, either individually or in the aggregate, have a Material Adverse Effect. All Tax Returns of or with respect to Weatherford or any of the Weatherford Subsidiaries have been audited by the applicable governmental authority, or the applicable statute of limitations has expired, for all periods up to and including, without limitation, the tax year ended December 31, 1987. There is no material claim against Weatherford or any of the Weatherford Subsidiaries with respect to any Taxes, and no material assessment, deficiency or adjustment has been asserted or proposed with respect to any Tax Return of or with respect to Weatherford or any of the Weatherford Subsidiaries that has not been adequately provided for in reserves established by Weatherford. The total amounts set up as liabilities for current and deferred Taxes in the consolidated financial statements included in the Weatherford Commission Filings have been prepared in accordance with generally accepted accounting principles and are sufficient to cover the payment of all material Taxes, including, without limitation, any penalties or interest thereon and whether or not assessed or disputed, that are, or are hereafter finally determined to be, or to have been, due with respect to the operations of Weatherford and the Weatherford Subsidiaries through the periods covered thereby. (k) Environmental. (i) There are no facts, conditions or circumstances known to Weatherford that could cause Weatherford or any Weatherford Subsidiary to incur any loss, liability, damage, cost or expense, either individually or in the aggregate, in excess of Weatherford's charges, accruals and reserves for environmental matters reflected on Weatherford's consolidated balance sheet contained in the most recent Weatherford Commission Filing, for (A) violations of Environmental Laws, (B) failure to obtain an Environmental Permit, (C) a requirement to install environmental or pollution control equipment, (D) removal, response or remedial costs related to Hazardous Materials or (E) personal injury, property damage or natural resources damage resulting from exposure to or releases of Hazardous Materials, except in each case where such loss, liability, damage, cost or expense would not have a Material Adverse Effect. (ii) The business and any other operations conducted by Weatherford or any Weatherford Subsidiary are in compliance with all applicable limitations, restrictions, conditions, standards, prohibitions, requirements and obligations established under applicable Environmental Laws, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect. -13- 18 (l) No Severance Payments. None of Weatherford or the Weatherford Subsidiaries will owe a severance payment or similar obligation to any of their respective employees, officers or directors as a result of the Merger or the transactions contemplated by this Agreement, nor will any of such persons be entitled to an increase in severance payments or other benefits as a result of the Merger or the transactions contemplated by this Agreement in the event of the subsequent termination of their employment.

(o) Title to Property. Except as set forth in the Weatherford Commission Filings, Weatherford and each of the Weatherford Subsidiaries have good and indefeasible title to all of their real properties purported to be owned in fee and good title to all their other material assets, free and clear of all mortgages, liens, charges and encumbrances other than Permitted Liens.

(d) No Approvals or Notices Required; No Conflict with Instruments to which Enterra is a Party. Neither the execution and delivery of this Agreement nor the performance by Enterra of its obligations hereunder, nor the consummation of the transactions contemplated hereby by Enterra, will (i) conflict with Enterra's Restated Certificate of Incorporation or bylaws; (ii) assuming satisfaction of the requirements set forth in clause (iii) below, violate any provision of law applicable to Enterra; (iii) except for (A) requirements of Federal and state securities law, (B) requirements arising out of the HSR Act, (C) requirements of filings in such foreign jurisdictions as may be applicable and (D) the filing of a certificate of merger in accordance with the DGCL, require any consent or approval of, or filing with or notice to, any public body or authority, domestic or foreign, under any provision of law applicable to Enterra; or (iv) require any consent, approval or notice under, or violate, breach, be in conflict with or constitute a default (or an event that, with notice or lapse of time or both, would constitute a default) under, or permit the termination of any provision of, or result in the creation or imposition of any lien upon any properties, assets or business of Enterra under, any note, bond, indenture, mortgage, deed of trust, lease, franchise, permit, authorization, license, contract, instrument or other agreement or commitment or any order, judgment or decree to which Enterra is a party or by which Enterra or any of its assets or properties is bound or encumbered, except those that have already been given, obtained or filed and except in any of the cases enumerated in clauses (ii) through (iv), those that, in the aggregate, would not have a Material Adverse Effect. (e) Commission Filings; Financial Statements. Since January 1, 1992, Enterra and each of the Enterra Subsidiaries have filed all reports, registration statements and other filings, together with any amendments required to be made with respect thereto, that they have been required to file with the Commission under the Securities Act and the Exchange Act. All reports, registration statements and other filings (including, without limitation, all notes, exhibits and -16- 21 schedules thereto and documents incorporated by reference therein) filed by Enterra with the Commission since January 1, 1992 through the date of this Agreement, together with any amendments thereto, are sometimes collectively referred to as the "Enterra Commission Filings". Enterra has heretofore delivered to Weatherford copies of the Enterra Commission Filings. As of the effectiveness dates declared by the Commission, in the case of registration statements, as of the mailing dates, in the case of proxy statements, or as of the filing dates with the Commission, in the case of all other Enterra Commission Filings, the Enterra Commission Filings complied, and the Proxy Statement (except with respect to information concerning Weatherford and the Weatherford Subsidiaries furnished by or on behalf of Weatherford to Enterra specifically for use therein) will comply, in all material respects with the Securities Act, the Exchange Act and the rules and regulations of the Commission promulgated thereunder, as applicable, and did not or will not, as the case may be, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. All material contracts of Enterra and the Enterra Subsidiaries have been included in the Enterra Commission Filings, except for those contracts not required to be filed pursuant to the rules and regulations of the Commission. Each of the audited consolidated financial statements (including, without limitation, any related notes or schedules) included or incorporated by reference in the Enterra Commission Filings was, and each of the audited consolidated financial statements to be included or incorporated by reference in the Proxy Statement (except for those financial statements of Weatherford and the Weatherford Subsidiaries furnished by or on behalf of Weatherford to Enterra specifically for use therein) will be, prepared in accordance with generally accepted accounting principles applied on a consistent basis (except as may be noted therein or in the notes or schedules thereto), and fairly presents or will fairly present, as the case may be, in all material respects, the consolidated financial position of Enterra and the Enterra Subsidiaries as of the dates thereof and the statements of income, cash flows and stockholders' equity for the periods then ended in accordance with generally accepted accounting principles. Each of the unaudited interim financial statements included or incorporated by reference in the Enterra Commission Filings was, and each of the unaudited consolidated financial statements to be included or incorporated by reference in the Proxy Statement (except for those financial statements of Weatherford and the Weatherford Subsidiaries furnished by or on behalf of Weatherford to Enterra specifically for use therein) will be, prepared in a manner consistent with the audited consolidated financial statements and generally accepted accounting principles. As of the date hereof, Enterra has no material liabilities, absolute or contingent, not reflected in the Enterra Commission Filings, except (i) liabilities not required under generally accepted accounting principles to be reflected on such financial statements or the notes thereto and (ii) liabilities incurred in the ordinary course of business since the date of such financial -17- 22 statements consistent with past operations and not relating to the borrowing of money. (f) Conduct of Business in the Ordinary Course; Absence of Certain Changes and Events. Since April 1, 1995, except as disclosed in the Enterra Commission Filings filed with the Commission since that date, Enterra and the Enterra Subsidiaries have conducted their business only in the ordinary and usual course, and there has not been (i) any Material Adverse Change in Enterra or any condition, event or development that reasonably may be expected to result in any Material Adverse Change; (ii) any change by Enterra in its accounting methods, principles or practices; (iii) any revaluation by Enterra or any of the Enterra Subsidiaries of any of its or their assets, including, without limitation, writing down the value of inventory or writing off notes or accounts receivable other than in the ordinary course of business; (iv) any entry by Enterra or any of the Enterra Subsidiaries into any commitment or transaction material to Enterra and the Enterra Subsidiaries, taken as a whole, other than in the ordinary course of business; (v) any declaration, setting aside or payment of any dividends or distributions in respect of the Enterra Common Stock, or any redemption, purchase or other acquisition of any of its securities or any securities of any of the Enterra Subsidiaries; (vi) any damage, destruction or loss (whether or not covered by insurance) materially adversely affecting the properties or business of Enterra and the Enterra Subsidiaries, taken as a whole; (vii) any increase in indebtedness for borrowed money; (viii) any granting of a security interest or lien on any property or assets of Enterra and the Enterra Subsidiaries, other than Permitted Liens; or (ix) any increase in or establishment of any bonus, insurance, severance, deferred compensation, pension, retirement, profit sharing, stock option (including, without limitation, the granting of stock options, stock appreciation rights, performance awards or restricted stock awards), stock purchase or other employee benefit plan or any other increase in the compensation payable or to become payable to any officers or key employees of Enterra or any of the Enterra Subsidiaries. (g) Certain Fees. Neither Enterra nor any of its officers, directors or employees, on behalf of Enterra or any of the Enterra Subsidiaries or its or their respective Boards of Directors (or any committee thereof), has employed any financial advisor, broker or finder or incurred any liability for any financial advisory, brokerage or finders' fees or commissions in connection with the transactions contemplated hereby. (h) Litigation. Except as disclosed in the Enterra Commission Filings, there are no claims, actions, suits, investigations or proceedings pending or, to the knowledge of Enterra, threatened against or affecting Enterra or any of the Enterra Subsidiaries or any of their respective properties at law or in equity, or any of their respective employee benefit plans or fiduciaries of such plans, or before or by any federal, state, municipal or other governmental agency or authority, or before any arbitration board or panel, wherever located, that, individually or in the aggregate, if adversely determined would have a Material Adverse Effect, or that involve the risk of criminal liability. -18- 23 (i) Employee Benefit Plans. The Enterra Disclosure Letter sets forth a complete and accurate list of: (i) each "employee welfare benefit plan" (as such term is defined in Section 3(1) of ERISA) (the "Enterra Welfare Plans"); (ii) each "employee pension benefit plan" (as such term is defined in Section 3(2) of ERISA) (the "Enterra Pension Plans"); and (iii) all other employee benefit agreements or arrangements, including, without limitation, deferred compensation plans, incentive plans, bonus plans or arrangements, stock option plans, stock purchase plans, golden parachute agreements, severance pay plans, dependent care plans, cafeteria plans, employee assistance programs, scholarship programs, employment contracts and other similar plans, agreements and arrangements (collectively, with the Enterra Welfare Plans and the Enterra Pension Plans, the "Enterra Benefit Plans"), that are currently in effect or were maintained within three years of the Closing Date, or have been approved before this date but are not yet effective, for the benefit of directors, officers, employees or former employees (or their beneficiaries) of Enterra, any of the Enterra Subsidiaries incorporated in the United States (the "Enterra U.S. Subsidiaries") or any member of a controlled group or affiliated service group (as defined in Sections 414(b), (c), (m) and (o) of the Code) that is incorporated or domiciled in the United States of which Enterra or any of the Enterra U.S. Subsidiaries is a member (collectively, the "Enterra Group"). Enterra and the Enterra U.S. Subsidiaries will provide to Weatherford, as to each Enterra Benefit Plan, as applicable, access to a complete and accurate copy of (i) such plan, agreement or arrangement; (ii) the trust, group annuity contract or other document that provides the funding for such plan; (iii) the most recent annual Form 5500, 990 and 1041 reports; (iv) the most recent actuarial report or valuation statement; (v) the most current summary plan description, handbook or other booklet that describes any Enterra Benefit Plan, and any summary of material modifications prepared after each such summary plan description; (vi) the most recent IRS determination letter and all rulings or determinations requested from the IRS subsequent to the date of such determination letter; and (vii) all other pending correspondence from the IRS or the Department of Labor received by any member of the Enterra Group that relates to such plan. Each Enterra Welfare Plan and Enterra Pension Plan (i) is in compliance with ERISA, including, without limitation, all reporting and disclosure requirements of Part 1 of Subtitle B of Title I of ERISA, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect; (ii) is in compliance with the Code, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect; (iii) has had the appropriate Form 5500 timely filed for any Enterra Pension Plan, if applicable, for each year of its existence -19- 24 and for any Enterra Welfare Plan for each year of its existence after 1987, except where the failure to cause such timely filing would not, either individually or in the aggregate, have a Material Adverse Effect; (iv) has not engaged in any transaction described in Section 406 or 407 of ERISA or Section 4975 of the Code unless it received or is entitled to an exemption under Section 408 of ERISA or Section 4975 of the Code, as applicable, or unless such transaction has been corrected and all applicable excise taxes paid or waived; (v) has no issue pending (other than the payment of benefits in the normal course or the qualification of the plan pursuant to an application pending before the IRS) nor any issue resolved adversely to the Enterra Group that, in either case, may subject the Enterra Group to the payment of a penalty, interest, tax or other amount, which, either individually or in the aggregate, would have a Material Adverse Effect; and (vi) can be unilaterally terminated or amended on no more than 90 days notice. No notice has been received by the Enterra Group of an increase or proposed increase in any premium relative to any Enterra Benefit Plan, and no amendment to any Enterra Benefit Plan within the last twelve months has increased the rate of employer contributions thereunder that, either individually or in the aggregate, would have a Material Adverse Effect. Each Enterra Benefit Plan that is intended to be a voluntary employee benefit association has been submitted to and approved by the IRS as exempt from federal income tax under Section 501(c)(9) of the Code or the applicable submission period relating to any such plan will not have ended prior to the Closing. No Enterra Benefit Plan will cause the Enterra Group to have liability for severance pay as a result of this Agreement. The Enterra Group does not provide employee post-retirement medical or health coverage or contribute to or maintain any employee welfare benefit plan that provides for health benefit coverage following termination of employment except as required by Section 4980B(f) of the Code or other applicable statute, nor has the Enterra Group made any representations, agreements, covenants or commitments to provide that coverage. Except for each Enterra Pension Plan that is an ERISA top-hat plan, each Enterra Pension Plan has been submitted to and approved as qualifying under Section 401(a) of the Code by the IRS or the applicable remedial amendment period relating to such plan will not have ended prior to the Closing. To the knowledge of Enterra, no facts have occurred that, if known by the IRS, could cause disqualification of any Enterra Pension Plan. Each Enterra Pension Plan to which Section 412 of the Code is applicable fully complies with the funding requirements of that Section and there is no accumulated funding deficiency as defined in Section 302(a)(2) of ERISA (whether or not waived) in any such plan. The Enterra Group has paid all premiums (including, without limitation, interest, charges and penalties for late payment) due the PBGC with respect to each Enterra Pension Plan for which premiums are required. No Enterra Pension Plan has been terminated under circumstances that would result in liability to the PBGC or the Enterra Group. There has been no "reportable event" (as defined in Section 4043(b) of ERISA and the regulations under that Section) with respect to any Enterra Pension Plan subject to Title IV of ERISA. -20- 25 With respect to each Enterra Pension Plan subject to Title IV of ERISA, the Enterra Group has not (i) ceased operations at a facility so as to become subject to the provisions of Section 4062(e) of ERISA, (ii) withdrawn as a substantial employer so as to become subject to the provisions of Section 4063 of ERISA or (iii) ceased making contributions on or before the Closing Date to any such plan subject to Section 4064(a) of ERISA to which the Enterra Group made contributions at any time during the six years prior to the Closing Date. Neither the Enterra Group nor any member thereof has made a complete or partial withdrawal from a multiemployer plan (as defined in Section 3(37) of ERISA) so as to incur withdrawal liability as defined in Section 4201 of ERISA. Enterra's subsidiaries incorporated outside of the United States and any benefit plans maintained by any of them for the benefit of their directors, officers, employees or former employees (or any of their beneficiaries) are in compliance with applicable laws pertaining to such plans in the jurisdictions of such subsidiaries, except where such failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect. (j) Taxes. All Tax Returns of or relating to any Taxes that are required to be filed on or before the Closing Date by or with respect to Enterra or any of the Enterra Subsidiaries have been or will be duly and timely filed, and all Taxes, including, without limitation, interest and penalties, due and payable pursuant to such Tax Returns have been paid or adequately provided for in reserves established by Enterra, except where the failure to file, pay or provide for would not, either individually or in the aggregate, have a Material Adverse Effect. All Tax Returns of or with respect to Enterra or any of the Enterra Subsidiaries have been audited by the applicable governmental authority, or the applicable statute of limitations has expired, for all periods up to and including, without limitation, the tax year ended December 31, 1987. There is no material claim against Enterra or any of the Enterra Subsidiaries with respect to any Taxes, and no material assessment, deficiency or adjustment has been asserted or proposed with respect to any Tax Return of or with respect to Enterra or any of the Enterra Subsidiaries that has not been adequately provided for in reserves established by Enterra. The total amounts set up as liabilities for current and deferred Taxes in the consolidated financial statements included in the Enterra Commission Filings have been prepared in accordance with generally accepted accounting principles and are sufficient to cover the payment of all material Taxes, including, without limitation, any penalties or interest thereon and whether or not assessed or disputed, that are, or are hereafter finally determined to be, or to have been, due with respect to the operations of Enterra and the Enterra Subsidiaries through the periods covered thereby. (k) Environmental. (i) There are no facts, conditions or circumstances known to Enterra that could cause Enterra or any Enterra Subsidiary to incur any loss, liability, damage, cost or expense, either individually or in the aggregate, in excess of Enterra's charges, accruals and reserves for -21- 26 environmental matters reflected on Enterra's consolidated balance sheet contained in the most recent Enterra Commission Filing, for (A) violations of Environmental Laws, (B) failure to obtain an Environmental Permit, (C) a requirement to install environmental or pollution control equipment, (D) removal, response or remedial costs related to Hazardous Materials or (E) personal injury, property damage or natural resources damage resulting from exposure to or releases of Hazardous Materials, except in each case where such loss, liability, damage, cost or expense would not have a Material Adverse Effect. (ii) The business and any other operations conducted by Enterra or any Enterra Subsidiary are in compliance with all applicable limitations, restrictions, conditions, standards, prohibitions, requirements and obligations established under applicable Environmental Laws, except where the failure to be in compliance would not, either individually or in the aggregate, have a Material Adverse Effect. (l) No Severance Payments. None of Enterra or the Enterra Subsidiaries will owe a severance payment or similar obligation to any of their respective employees, officers or directors as a result of the Merger or the transactions contemplated by this Agreement, nor will any of such persons be entitled to an increase in severance payments or other benefits as a result of the Merger or the transactions contemplated by this Agreement in the event of the subsequent termination of their employment. (m) Voting Requirements. The affirmative vote of the holders of a majority of the outstanding shares of Enterra Common Stock is the only vote of the holders of any class or series of the capital stock of Enterra necessary to approve this Agreement and the Merger. (n) Insurance. The Enterra Disclosure Letter sets forth all policies of insurance currently in effect relating to the business or operations of Enterra and the Enterra Subsidiaries. (o) Title to Property. Except as set forth in the Enterra Commission Filings, Enterra and each of the Enterra Subsidiaries have good and indefeasible title to all of their real properties purported to be owned in fee and good title to all their other material assets, free and clear of all mortgages, liens, charges and encumbrances other than Permitted Liens. (p) Enterra Actions. As of the date hereof, the Board of Directors of Enterra (at a meeting duly called and held) has resolved to recommend approval and adoption of this Agreement and the Merger by the stockholders of Enterra. Simmons & Company International, Inc. has delivered to the Board of Directors of Enterra its opinion that the consideration to be received by the holders of Enterra Common Stock in the Merger is fair from a financial point of view to such holders. -22- 27 ARTICLE III COVENANTS OF WEATHERFORD PRIOR TO THE EFFECTIVE TIME 3.1 Conduct of Business by Weatherford Pending the Merger.

Without limiting the foregoing, it is understood that any violation of the restrictions set forth in the preceding sentence by any officer, director or employee of Weatherford or any of the Weatherford Subsidiaries or any investment banker, attorney or other advisor, agent or representative of Weatherford, whether or not such person is purporting to act on behalf of Weatherford or otherwise, shall be deemed to be a material breach of this Agreement by Weatherford.

Enterra may terminate this Agreement pursuant to the preceding sentence only if the stockholders of Enterra shall not yet have voted upon the Merger and Enterra shall have paid to Weatherford the Termination Fee. Nothing contained herein shall prohibit Enterra from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) of the Exchange Act -44- 49 provided that Enterra does not withdraw or modify its position with respect to the Merger or take any action having such effect or approve or recommend an Enterra Takeover Proposal. For purposes of this Agreement, an "Enterra Superior Proposal" means any bona fide Enterra Takeover Proposal to merge with or acquire, directly or indirectly, all of the voting stock then outstanding or all or substantially all of the assets of Enterra, and otherwise on terms that the Board of Directors of Enterra determines in its good faith reasonable judgment (based on the written advice of a financial advisor of nationally recognized reputation) to be more favorable to Enterra's stockholders than the Merger.

If a Qualifying Offer is opposed by the board of directors of Weatherford, then, from and after the eleventh business day after commencement of such Qualifying Offer, any member of the FRC Group may tender or exchange shares of Weatherford Voting Securities pursuant to such Qualifying Offer only if (i) no tender or exchange of, or indication of an intention to tender or exchange, Weatherford Voting Securities is made by any member of the FRC Group earlier than 24 hours prior to the expiration of any time after which Weatherford Voting Securities tendered may be treated less favorably than Weatherford Voting Securities tendered or exchanged prior thereto, and (ii) a binding agreement is reached with the bidder or offeror prior to any tender or exchange specifying that only such number of Weatherford Voting Securities submitted for tender or exchange shall be accepted by the bidder or offeror as are equal to (A) the percentage of such Weatherford Voting Securities not beneficially owned by the FRC Group that have been tendered or exchanged, multiplied by (B) the total number of such Weatherford Voting Securities beneficially owned by the member of the FRC Group. 4.7.

(b) Upon the Effective Time, the number of directors of Weatherford shall be established as 10 directors, and two individuals designated by the FRC Group shall be elected as directors of Weatherford, subject to the provisions of this Agreement. The parties hereto agree that the number of directors -8- 9 of Weatherford may not be increased above 10 without the approval of a (i) a majority of the directors and (ii) all of the directors designated by the FRC Group. From and after the Effective Time, the FRC Group and the directors designated by the FRC Group shall take no action to reduce the number of directors of Weatherford below 10 directors. (c) For purposes of this Agreement, directors "designated by the FRC Group" shall include directors designated by the FRC Group as set forth in Section 5.22 of the Merger Agreement or designated by certain members of the FRC Group as anticipated by this Section 5, and any other directors of Weatherford affiliated or associated with any member of the FRC Group. (d) From and after the Effective Time, as long as the FRC Group beneficially owns at least 15% of the Combined Voting Power of all Weatherford Voting Securities, two of (i) First Reserve Secured Energy Assets Fund, Limited Partnership, (ii) First Reserve Fund V, Limited Partnership, (iii) First Reserve Fund V-2, Limited Partnership and (iv) First Reserve Fund VI, Limited Partnership (the "Designating First Reserve Funds") as shall be selected by FRC shall have the right to designate one director of Weatherford, for a total of two directors of Weatherford (it being understood that the FRC Group shall not have more than two designees on the board of directors of Weatherford at any time); provided, however, that: (i) At any time when the FRC Group beneficially owns less than 15% but at least 10% of the Combined Voting Power of all Weatherford Voting Securities, one of the Designating First Reserve Funds, to be selected by FRC, shall lose its right to designate a director of Weatherford, and such Designating First Reserve Fund shall cause its designee on the board of directors of Weatherford to resign forthwith such that only one designee of the FRC Group remains on the board of directors of Weatherford; and (ii) At any time when the FRC Group beneficially owns less than 10% of the Combined Voting Power of all Weatherford Voting Securities, none of the FRC Group shall have the right to designate any directors of Weatherford, and the Designating First Reserve Fund whose designee remains on Weatherford's board of directors shall cause its designee to resign forthwith such that no designee of the FRC Group remains on the board of directors of Weatherford, it being understood that at any time that the FRC Group beneficially owns less than 10% of the Combined Voting Power of Weatherford Voting Securities no member of the FRC -9- 10 Group shall seek representation on the board of directors of Weatherford. (e) Weatherford shall take all necessary or appropriate action to (i) assist in the nomination for election as directors of those persons designated by the Designating First Reserve Funds as are entitled to election to the board of directors of Weatherford pursuant to the provisions of this Section 5, (ii) have at least one of the designees of the FRC Group serve on each committee of the board of directors of Weatherford as long as the Designating First Reserve Funds have designated at least two directors pursuant to the provisions of this Section 5 and (iii) where two designees of the FRC Group are serving as directors of Weatherford, have each such designee serve in different classes of directors. The Designating First Reserve Funds shall cause their designees on the board of directors of Weatherford to take all necessary or appropriate action to assist in the nomination for election as directors of such other nominees as may be selected by a majority of the directors of Weatherford then in office who were not designated by the Designating First Reserve Funds, and the FRC Group shall vote all Weatherford Voting Securities owned of record by any member of the FRC Group, and shall cause all Weatherford Voting Securities owned beneficially by any member of the FRC Group to be voted, for the election of such other nominees as well as for the election of all nominees of the Designating First Reserve Funds designated by them pursuant to this Section 5. (f) At any time that one of the Designating First Reserve Funds does not have a representative serving as a director of Weatherford, an individual designated by such Designating First Reserve Fund shall have the right to attend all meetings of the board of directors in a nonvoting observer capacity, to receive notice of such meetings and to receive the information provided by Weatherford to its board of directors; provided, however, that Weatherford may require as a condition precedent to any of such person's rights under this section that such person agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information received in connection with board meetings or otherwise; and, provided further, that Weatherford reserves the right not to provide information to such person, and to exclude such person from any meeting or portion thereof, if delivery of such information or attendance at such meeting would adversely affect the attorney- client privilege between Weatherford and its counsel. The observer right provided in this Section 5(f) may be exercised (i) only if (and then only so long as) the Designating First Reserve Fund has been advised in writing by counsel to such fund that exercise of this right is reasonably necessary for such Designating First Reserve Fund to qualify through its investment in Weatherford as a "venture capital operating company" as such term is defined in applicable U.S. Department of Labor -10- 11 regulations. Notwithstanding the above, the FRC Group agrees to use its reasonable best efforts to cause the Designating First Reserve Funds to qualify as a "venture capital operating company" under these regulations without exercise of its rights under this Section. (g) Except as set forth in Section 5(e) above in respect of the election of directors of Weatherford, each member of the FRC Group shall vote all Weatherford Voting Securities owned of record by any member of the FRC Group, and shall cause all Weatherford Voting Securities owned beneficially by any member of the FRC Group to be voted, at the sole election of such members of the FRC Group, either (i) in accordance with the recommendations of a majority of the board of directors, or (ii) in the same proportions for, against and abstaining in respect of any matter as the holders of record of Weatherford Voting Securities other than those beneficially owned by the FRC Group that are entitled to vote on such matter vote their Weatherford Voting Securities. 6. Registration Rights. Weatherford covenants and agrees as follows: 6.1. Definitions. For purposes of this Section 6: (a) The term "register," "registered" and "registration" refer to a registration effected by preparing and filing a registration statement in compliance with the Act. (b) The term "Registrable Securities" means (i) the Weatherford Common Stock issuable to the First Reserve Funds as of the Effective Time in connection with the Merger, and (ii) any Weatherford Common Stock issued as (or issuable upon the conversion, exchange or exercise of any warrant, right or other security which is issued as) a dividend or other distribution with respect to such Weatherford Common Stock; provided, however, that Weatherford Common Stock sold, transferred or disposed of in accordance with Section 4.2 of the Agreement to a person to whom registration rights may not be assigned pursuant to Section 6.13 of the Agreement shall no longer thereafter be considered Registrable Securities. (c) The term "Holder" means any member of the FRC Group that (i) has signed this Agreement and (ii) owns of record Registrable Securities. (d) The term "Form S-3" means such form under the Act as in effect on the date hereof or any registration form under the Act subsequently adopted by the SEC which permits inclusion or incorporation of substantially all the required information regarding Weatherford by reference to other documents filed by Weatherford with the SEC. -11- 12 6.2. Request for Registration. (a) If, at any time commencing three months after the Effective Time of the Merger, Weatherford shall receive a written request from the Holders of at least 25% of the Registrable Securities then outstanding that Weatherford file a registration statement under the Act covering the registration of at least 25% of the Registrable Securities then outstanding (or a lesser percent if the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $25,000,000), then Weatherford shall, within 10 days after the receipt thereof, give written notice of such request to all Holders, and shall, subject to the limitations of Section 6.2(b), effect as soon as practicable, and in any event within 45 days after the receipt of such request, the registration under the Act of all Registrable Securities which the Holders request to be registered within 15 days after the mailing of such notice by Weatherford in accordance with Section 10.3. It is understood that all calculations in this Agreement in respect of a specified percentage of Registrable Securities then outstanding are to be made only in respect of the total number of such Registrable Securities, as defined in Section 6.1(b) above, then outstanding, and not in respect of the total number of shares of Weatherford Common Stock then outstanding. (b) If the Holders initiating the registration request hereunder ("Initiating Holders") intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise Weatherford as a part of their request made pursuant to this Section 6.2 and Weatherford shall include such information in the written notice referred to in subsection 6.2(a). In such event, the right of any Holder to include Registrable Securities in such registration shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute Registrable Securities through such underwriting shall (together with Weatherford as provided in subsection 6.4(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by Weatherford and reasonably acceptable to a majority in interest of the Initiating Holders. Weatherford at its sole discretion may offer a right to participate in any registration statement filed pursuant to this Section 6.2 to other stockholders of Weatherford Common Stock, and may itself participate in any registration statement filed pursuant to this Section 6.2 hereof. However, notwithstanding any other provision of this Section 6.2, if the offering is an underwritten offering and the lead managing underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares of Weatherford Common Stock to be underwritten, then the total number of shares of Common Stock to be -12- 13 underwritten shall be reduced, with such reduction coming first from selling stockholders who are not Holders, and then from Weatherford. If further reduction is required, Weatherford shall so advise all Holders of Registrable Securities that would have otherwise been underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders thereof, including the Initiating Holders, in proportion (as nearly as practicable) to the amount of Registrable Securities sought to be registered by each Holder. (c) Weatherford is obligated to effect only four such registrations pursuant to this Section 6.2. (d) Notwithstanding the foregoing, if Weatherford shall furnish to Holders requesting a registration statement pursuant to this Section 6.2, a certificate signed by the President of Weatherford stating that in the good faith judgment of a majority of the directors of Weatherford then in office who were not designated by the FRC Group, it would be materially detrimental to Weatherford for such registration statement to be filed, Weatherford shall have the right to defer such filing for a period of not more than 60 days after receipt of the request of the Initiating Holders; provided, however, that Weatherford may not utilize this right more than once in any 12-month period. 6.3. Piggyback Registration. If (but without any obligation to do so) Weatherford proposes to register any of its Common Stock under the Act in connection with the public offering of such Common Stock by Weatherford solely for cash (other than a registration relating solely to the sale of securities to participants in a dividend reinvestment plan, stock plan or employee benefit plan; a registration relating solely to the issuance of securities in connection with an acquisition; or a registration on any form which does not permit inclusion of selling stockholders), or Weatherford proposes to register any of its securities on behalf of a holder exercising demand registration rights similar to those set forth in Section 6.2 above, Weatherford shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within 15 days after mailing of such notice by Weatherford in accordance with Section 10.3, Weatherford shall, subject to the provisions of Section 6.8, cause to be registered under the Act all of the Registrable Securities that each such Holder has requested to be registered. 6.4. Obligations of Weatherford. Whenever required under this Section 6 to effect the registration of any Registrable Securities, Weatherford shall, as expeditiously as reasonably possible: -13- 14 (a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to 90 days. (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement. (c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. (d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that Weatherford shall not be required to qualify to do business or to file a general consent to service of process in any such states of jurisdictions. (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriters of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and then use its best efforts to promptly correct such statement or omission. Notwithstanding the foregoing and anything to the contrary set forth in this Section, each Holder acknowledges that there may occasionally be times when Weatherford must suspend the use of the prospectus forming a part of the registration statement until such time as an amendment to the registration statement has been filed by Weatherford and declared effective by the SEC, or until such time as Weatherford has filed an appropriate report with the -14- 15 SEC pursuant to the Exchange Act. Each Holder hereby covenants that it will not sell any shares of Common Stock pursuant to said prospectus during the period commencing at the time at which Weatherford gives the Holder notice of the suspension of the use of said prospectus and ending at the time Weatherford gives the Holder notice that it may thereafter effect sales pursuant to said prospectus. Weatherford shall only be able to suspend the use of said prospectus for periods aggregating no more than 30 days in respect of any registration. 6.5 Furnish Information. It shall be a condition precedent to the obligations of Weatherford to take any action pursuant to this Section 6 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to Weatherford such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to affect the registration of such Holder's Registrable Securities and as may be required from time to time to keep such registration current. 6.6. Expenses of Demand Registration. All expenses incurred by or on behalf of Weatherford in connection with registrations, filings or qualifications pursuant to Section 6.2, including, without limitation, all registration, filing and qualification fees, printers' and accounting fees, and fees and disbursements of counsel for Weatherford, shall be borne by Weatherford; provided, however, that Weatherford shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 6.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall reimburse Weatherford promptly for all such reasonable expenses), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 6.2. In no event shall Weatherford be obligated to bear underwriting discounts and commissions and the fees and expenses of counsel to the selling Holders. 6.7. Expenses of Piggyback Registration. Weatherford shall bear and pay all expenses incurred by or on behalf of Weatherford in connection with any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Section 6.3 for each Holder, including, without limitation, all registration, filing, and qualification fees, printing and accounting fees and fees and disbursements of counsel for Weatherford relating or allocable thereto, but excluding underwriting discounts and commissions relating to Registrable Securities and the fees and disbursements of counsel for the selling Holders. -15- 16 6.8. Underwriting Requirements. In connection with any offering involving an underwriting of shares being issued by Weatherford, Weatherford shall not be required under Section 6.3 to include any of the Holders' Registrable Securities in such underwriting unless they accept the terms of the underwriting as agreed upon between Weatherford and the underwriters selected by it. If the total amount of securities, including Registrable Securities, requested by Holders and other stockholders to be included in such offering exceeds the amount of securities sold other than by Weatherford that the underwriters reasonably believe compatible with the success of the offering, then Weatherford shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters believe will not jeopardize the success of the offering. To achieve any necessary reduction in the securities to be sold, the securities to be excluded from the offering shall first be selected (in each case, pro rata among such class of holders according to the total amount of securities proposed to be included in the registration statement or in such other proportions as shall mutually be agreed to by such class of holders) in the following order: (i) first, securities being included on behalf of holders other than members of the FRC Group shall be excluded, except as provided in (iii) below; (ii) next, if additional securities must be excluded, Registrable Securities included pursuant to Section 6.3 shall be excluded; (iii) thereafter, if additional securities must be excluded, securities included on behalf of a holder exercising demand registration rights similar to those set forth in Section 6.2 shall be excluded, and (iv) finally, if additional securities must be excluded, securities offered by Weatherford shall be excluded. 6.9. Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 6. 6.10. Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 6: (a) To the extent permitted by law, Weatherford will indemnify and hold harmless each Holder and the affiliates of such Holder, and their respective directors, officers, general and limited partners, agents and representatives (and the directors, officers, affiliates and controlling persons thereof), and each other person, if any, who controls such Holder within the meaning of the Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are -16- 17 based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus (but only if such is not corrected in the final prospectus) contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading (but only if such is not corrected in the final prospectus), or (iii) any violation or alleged violation by Weatherford in connection with the registration of Registrable Securities under the Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Act, the Exchange Act or any state securities law; and Weatherford will pay to each such Holder, affiliate or controlling person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 6.10(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of Weatherford (which consent shall not be unreasonably withheld), nor shall Weatherford be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder or controlling person. (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless Weatherford, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls Weatherford within the meaning of the Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this subsection 6.10(b), in connection with investigating or defending any such lose, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 6.10(b) shall not apply to amounts paid in settlement of any such loss, -17- 18 claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall any indemnity under this Section 6.10(b) exceed the gross proceeds from the offering received by such Holder. (c) Promptly after receipt by an indemnified party under this Section 6.10 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 6.10, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties. The failure to deliver written notice to the indemnifying party within a reasonable time after the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 6.10, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 6.10. The indemnified party shall have the right, but not the obligation, to participate in the defense of any action referred to above through counsel of its own choosing and shall have the right, but not the obligation, to assert any and all separate defenses, cross claims or counterclaims which it may have, and the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of such counsel has been specifically authorized in advance by the indemnifying party, (ii) there is a conflict of interest that prevents counsel for the indemnifying party from adequately representing the interests of the indemnified party, (iii) the indemnifying party does not employ counsel that is reasonably satisfactory to the indemnified party, or (iv) the indemnifying party fails to assume the defense or does not reasonably contest such action in good faith, in which case, if the indemnified party notifies the indemnifying party that it elects to employ separate counsel, the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party and the reasonable fees and expenses of such separate counsel shall be borne by the indemnifying party; provided, however, that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties. (d) The obligations of Weatherford and the Holders under this Section 6.10 shall survive the completion of -18- 19 any offering of Registrable Securities in a registration statement under this Section 6. 6.11. Reports Under the Exchange Act. With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of Weatherford to the public without registration or pursuant to a registration on Form S-3, Weatherford agrees to: (a) use its best efforts to make and keep public information available, as those terms are understood and defined in Rule 144; (b) use its best efforts to file with the SEC in a timely manner all reports and other documents required under the Act and the Exchange Act; and (c) furnish to any Holder forthwith upon request (i) a written statement by Weatherford as to its compliance with the reporting requirements of Rule 144, or as to whether it qualifies as a registrant whose securities may be resold pursuant to Form S-3, (ii) a copy of the most recent annual or quarterly report of Weatherford and such other reports and documents so filed by Weatherford, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 6.12. Form S-3 Registration. In case Weatherford shall receive from any Holder or Holders of at least 10% of the Registrable Securities then outstanding (or a lesser percent if the anticipated aggregate offering price, net of discounts and commissions, would exceed $1,000,000) a written request or requests that Weatherford effect a registration on Form S-3 not involving an underwriting and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, Weatherford will: (a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and (b) as soon as practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder's or Holders' Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within 15 days after receipt of such written notice from Weatherford; provided, however, that -19- 20 Weatherford shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 6.12: (1) if Form S-3 is not available for such offering by the Holders; (2) if the Holders, together with the holders of any other securities of Weatherford entitled to include securities in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any discounts or commissions) of less than $1,000,000; (3) if Weatherford shall furnish to the Holders a certificate signed by the President of Weatherford stating that in the good faith judgment of a majority of the directors of Weatherford then in office who were not designated by the FRC Group, it would be materially detrimental to Weatherford for such Form S-3 Registration to be effected at such time, in which event Weatherford shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than 60 days after receipt of the request of the Holder or Holders under this Section 6.12; provided, however, that Weatherford shall not utilize this right more than once in any 12-month period; (4) if Weatherford has, within the 12-month period preceding the date of such request, already effected a registration on Form S-3 for the Holders pursuant to this Section 6.12; or (5) in any particular jurisdiction in which Weatherford would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. (c) Subject to the foregoing, Weatherford shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. All expenses incurred by or on behalf of Weatherford in connection with the registrations requested pursuant to Section 6.12, including (without limitation) all registration, filing, qualification, printer's and accounting fees and the fees and disbursements of counsel for Weatherford, shall be borne by Weatherford, except that any discounts or commissions associated with Registrable Securities and the fees and disbursements of counsel for the selling Holder or Holders shall be borne by the Holder or Holders participating in the Form S-3 Registration. Registrations effected pursuant to this Section 6.12 shall not be counted as demands for registration or registrations effected pursuant to Sections 6.2. 6.13. No Assignment of Registration Rights. The rights to cause Weatherford to register Registrable Securities pursuant to this Section 6 may only be assigned by a Holder to a transferee or assignee of any Registrable Securities if (i) such transferee or assignee is a member of the FRC Group that has executed this Agreement, and (ii) immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act. -20- 21 6.14. Limitations on Subsequent Registration Rights. From and after the date of this Agreement, Weatherford shall not, without the prior written consent of the Holders of a majority of the outstanding Registrable Securities (or, prior to the Effective Time of the Merger, without the prior written consent of FRC), enter into any agreement with any holder or prospective holder of any securities of Weatherford which would allow such holder or prospective holder to include such securities in any registration filed under Sections 6.2 or 6.3 hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of its securities will not reduce the amount of the Registrable Securities of the Holders which is included. 6.15. Waiver Procedures. The observance by Weatherford of any provision of this Section 6 may be waived (either generally or in a particular instance and either retroactively or prospectively) with the written consent of the holders of a majority of the Registrable Securities then outstanding, and any waiver effected in accordance with this paragraph shall be binding upon each Holder of Registrable Securities. 6.16. "Market Stand-off" Agreement. Any Holder of Registrable Securities, if requested by an underwriter of any registered public offering of Weatherford securities being sold in a firm commitment underwriting, agrees not to sell or otherwise transfer or dispose of any Common Stock (or other Weatherford voting Securities) held by such Holder other than shares of Registrable Securities included in the registration, during a period of up to 90 days following the effective date of the registration statement, provided that all other persons selling securities in such underwritten public offering and all officers and directors of Weatherford shall enter into similar agreements. Such agreement shall be in writing in the form reasonably satisfactory to Weatherford and such underwriter. Weatherford may impose stop-transfer instructions with respect to the securities subject to the foregoing restriction until the end of the required stand-off period. Section 7.

From and after such times as the FRC Group beneficially owns in the aggregate Weatherford Voting Securities representing 10% or more of the Combined Voting Power, all restrictions upon and covenants of the FRC Group and Weatherford set forth in this Agreement shall again be applicable until the Termination Date. All percentages in this Section shall be calculated in accordance with the provisions of Section 4.1. Section 8. Legend and Stop Transfer Order. To assist in effectuating the provisions of this Agreement, the FRC Group hereby consents (i) to the placement, in connection with the Merger or otherwise within 10 business days after any Weatherford Voting Securities become subject to the provisions of this Agreement, of the following legend on all certificates representing ownership of Weatherford Voting Securities owned of record by any member of the FRC Group or by any person where a member of the FRC Group is the beneficial owner thereof, until such shares are sold, transferred or disposed in a manner permitted hereby to a person who is not then a member of the FRC Group: The shares represented by this certificate are subject to the provisions of an Agreement among Weatherford Corporation, First Reserve Corporation and certain limited partnerships under control of or common control with First Reserve Corporation, and may not be sold, transferred, pledged, hypothecated or otherwise disposed of except in accordance -22- 23 therewith.

Weatherford agrees to remove promptly all legends and stop transfer orders with respect to the transfer of Weatherford Voting Securities being made to a person who is not then a member of the FRC Group in compliance with the provisions of this Agreement. Section 9. Remedies. (a) The FRC Group acknowledges and agrees that (i) the provisions of this Agreement are reasonable and necessary to protect the proper and legitimate interests of the parties hereto, and (ii) Weatherford and the FRC Group would be irreparably damaged in the event any of the provisions of this Agreement were not performed by the other parties hereto in accordance with their specific terms or were otherwise breached.
