INFORMATION TO BE INCLUDED IN REPORT Item 5. Other Events The registrant may, at its option, report under this item any events, with respect to which information is not otherwise called for by this form, that the registrant deems of importance to security holders. On April 10, 2001 registrant issued a press release entitled "Halliburton Completes Sale of Dresser Equipment Group" pertaining, among other things, to an announcement that registrant has completed the sale of Dresser Equipment Group (DEG), now called Dresser, Inc., to an investor group consisting primarily of First Reserve Corporation and Odyssey Investment Partners, LLC. The value of the sale is $1.55 billion in cash and assumed liabilities. For registrant, the transaction results in a $500 million pre-tax gain and a $300 million after-tax gain, or $0.69 per share. A subsidiary of registrant will retain ownership of 5.1 percent of DEG. After adjustments for assumed liabilities and changes in net assets since the date of the purchase agreement, registrant received approximately $1.3 billion in net cash proceeds. After payment of taxes and sale expenses, registrant will net approximately $1.0 billion in cash. All above amounts are subject to adjustments based upon the DEG balance sheet at closing. Item 7.

This Agreement amends and restates in its entirety that certain Agreement and Plan of Recapitalization dated as of January 30, 2001 by and among the Parent, the Seller and the Acquiror, as amended by Amendatory Agreement No. 1 thereto, dated March 2001, and Amendatory Agreement No. 2 thereto, dated March 2001. References in this Agreement to the "date of this Agreement," or "the date hereof" shall refer to January 30, 2001. R E C I T A L S: The Parent has determined to redeploy a significant portion of its assets. Accordingly, the Parent desires to sell, and the Acquiror has determined to purchase, certain interests in the Parent's businesses relating to, among other things, the design, manufacturing and marketing of engineered measurement, flow control and power systems for customers primarily in the energy industry. In order to accomplish this transaction, the Parent will, in consultation with the Acquiror and in the manner set forth herein, prior to the First Closing effect the Reorganization described in Annex B of the various legal entities that comprise the Dresser Equipment Group.

On March 28, 2001, DEGI changed its legal name from "Dresser Equipment Group, Inc." to "Dresser, Inc." References in this Agreement (including the exhibits, annexes and schedules hereto) to "Dresser Equipment Group, Inc." shall mean Dresser, Inc. NOW, THEREFORE, the parties hereto, in consideration of the premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, agree as follows: ARTICLE I DEFINITIONS HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION

Industries in connection with the Merger shall be increased by the amount of the cash consideration received by DEGI against the issuance of such Management Shares. (d) Any Management Shares issued by DEGI prior to the First Closing shall be sold to management employees at a price per share not less than an amount equal to the Merger Consideration plus the BV Consideration divided by the number of shares of DEGI Common Stock to be converted by Dresser Industries in the Merger as determined pursuant to clause (ii) of subsection 2.01(c) before giving effect to clause (iii) of subsection 2.01(c). Section 2.02. Sale and Purchase of BV Companies. On the terms and subject to the conditions contained in this Agreement, the Parent agrees to cause the Seller to engage at the Second Closing in the following transactions, and the Acquiror agrees to cause each of the Buyers to engage at the Second Closing in the following transactions: The Seller shall assign to the appropriate Buyer as indicated on Annex C hereto, and such Buyer shall accept, the Equity Securities of the BV Company whose name is set forth next to the name of such Buyer on Annex C hereto. In consideration for such assignments, the Buyers shall pay to the Seller cash in U.S. Dollars in an aggregate amount equal to (a) the BV Preliminary Purchase Price Percentage times the Preliminary Purchase Price as adjusted by (b) a portion of the Purchase Price Adjustment determined in accordance with the Allocation Procedures (the "BV Consideration"). Section 2.03. Cash Consideration. (a) The aggregate cash consideration to be paid to Dresser Industries and the Seller for engaging in the transactions contemplated by Sections 2.01 and 2.02 herein shall consist of the Purchase Price. The "Purchase Price" shall be equal to the Preliminary Purchase Price as adjusted by the Purchase Price Adjustment in accordance with Sections 2.08 and 2.09. (b) The parties hereto have agreed that the "Preliminary Purchase Price" shall be equal to (i) U.S. $1,309,111,797 (one billion three hundred nine million one hundred eleven thousand seven hundred ninety-seven dollars) less (ii) the amount which, when taken together with the aggregate consideration paid to acquire the Management Shares, equals 5.1% of the Equity of DEGI. Section 2.04. The Closings. (a) The transactions contemplated by Section 2.01 shall be consummated (the "First Closing") on the date and at the time and place determined pursuant to this subsection (a). The First Closing shall be held at the offices of Latham & Watkins, 885 Third Avenue, New York, New York 10022 on the Closing Date. The "Closing Date" shall be the fifteenth (15th) Business Day following the date on which the Closing Conditions (other than conditions that can be satisfied only by delivery of certificates or other documents at the Closings and where such delivery is in the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 4

control of a party hereto) have been fulfilled or waived. If such date is not a Business Day, then the Closing Date shall be the next succeeding Business Day. (b) Upon fulfillment or waiver of the Closing Conditions to which reference is made in subsection (a) of this Section, either the Parent or the Acquiror may give the other notice thereof (the "Closing Notice") and the date of receipt of such Closing Notice determined in accordance with Section 14.01 shall be the first Business Day of the time periods therein referenced. (c) Immediately following the First Closing, the transactions contemplated by Section 2.02 shall be consummated (the "Second Closing"). The Second Closing shall be held at the same location as the First Closing. The consummation of the Second Closing shall be a condition subsequent to the consummation of the First Closing, such that if the Second Closing shall not occur immediately following the First Closing either the Parent or the Acquiror shall be entitled to cause the rescission of the transactions consummated at the First Closing. Section 2.05. Pre-Closing Transactions. (a) Prior to the First Closing, the Parent shall effect the Reorganization described in Annex B. The Parent and the Acquiror shall cooperate with each other with respect to the implementation of the Reorganization described in Annex B, including actions involving filings with Governmental Authorities, the execution of agreements, transfer documents and similar instruments and the issuance of securities. If the Parent and the Acquiror consent in writing to any action that is inconsistent with the transactions described on Annex B hereto, then Annex B shall, automatically and without further action by the parties hereto, be deemed to have been amended to the extent necessary to permit such action. (b) The Parent shall prior to the First Closing cause the outstanding DEGI Common Stock to be subdivided pursuant to a stock split on a basis that is mutually satisfactory to the Acquiror and the Parent. (c) In any case in which the Reorganization, as the Reorganization may be amended as provided in subsection (a) of this Section 2.05 prior to the First Closing, requires that a member of a Company Group be "formed" or otherwise implies that it must be organized de novo, the parties hereto acknowledge that counsel to, or other representatives of, the Parent or the Acquiror may, in lieu of a legal entity organized de novo, use a previously formed legal entity "off the shelf" for such purpose ( herein called a "Shelf Entity"). Section 2.06. Transactions at the First Closing. Subject to the terms and conditions of this Agreement, the Parent shall at the First Closing cause DEGI to do and perform the following actions and to deliver the following documents, and the Acquiror shall do and perform the following actions HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 5

and deliver the following documents. At the First Closing, the following events shall occur, each event being (i) conditioned on the occurrence or waiver of each other event and (ii) deemed to occur simultaneously with each other event: (a) Financial Transactions: (i) The Acquiror shall purchase from the Transitory Merger Sub upon original issue shares of common stock for cash in the amount of the Investment; (ii) DEGI shall execute and deliver the Loan Documents against the funding of the full amount of the Loan to DEGI by wire transfer of immediately available funds to the wire transfer address of DEGI provided in written instructions to the Acquiror not less than three (3) Business Days prior to the Closing Date; and (iii) the Parent and the Acquiror shall cause the Merger to be effected in accordance with subsection (c) of Section 2.01; provided, however, that the amount of cash to be paid to Dresser Industries pursuant to the Merger at the time of the First Closing (subject to adjustment pursuant to Sections 2.08 and 2.09) shall be an aggregate amount equal to the DEGI Group Preliminary Purchase Price Percentage times the Estimated Purchase Price. The consideration to be received by Dresser Industries pursuant to the Merger shall be paid to Dresser Industries by wire transfer of immediately available funds to the wire transfer address of Dresser Industries provided in written instructions by the Acquiror not less than three (3) Business Days prior to the Closing Date. (b) Ancillary Agreements. The parties to each Ancillary Agreement shall execute and deliver such Ancillary Agreement. (c) Intercompany Indebtedness. Any Intercompany Indebtedness owed at the Closing Date by any member of the Parent Group to any member of the DEGI Group or by any member of the DEGI Group to any member of the Parent Group shall be discharged, whether, at the election of the Parent (provided, that the Parent shall cooperate with the Acquiror to structure such discharge in the manner that is most tax-efficient to all the parties), by payment by the obligor or by release and forgiveness by the obligee pursuant to a written release, in form and substance substantially similar to the form thereof attached hereto as Appendix II, executed and delivered at the First Closing. The Intercompany Indebtedness has not been reflected in the Initial Balance Sheet, and will not be reflected in the Estimated or Closing Balance Sheet, as an asset or liability and, consequently, shall have no effect on the calculation of the Purchase Price Adjustment hereunder. (d) The Parent shall at the First Closing execute, where appropriate, and deliver to the Acquiror the following documents: HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 6

(i) A release, in form and substance substantially similar to the form thereof attached hereto as Appendix III, by the Parent on behalf of itself and the Parent Group of all claims that they may have against any member of the DEGI Group with respect to the operation or conduct of the Businesses prior to the Closing Date; (ii) A certificate in the form required by Treasury Regulation Section 1.1445-2; and (iii) such other documents and instruments as shall evidence fulfillment or waiver of the Closing Conditions.

Subject to the terms of this Agreement and to the condition that the First Closing shall have been effected, the Parent shall cause the Seller at the Second Closing to do and perform the following actions and to deliver the following documents, and the Acquiror shall do and perform the following actions and cause the Buyers at the Second Closing to do and perform the following actions and to deliver the following documents. At the Second Closing, the following events shall occur, each event being (i) conditioned on the occurrence or waiver of each other event and (ii) deemed, except as otherwise provided in subsection (b) of this Section, to occur simultaneously with each other event: (a) The Parent shall cause the Seller to deliver, in the sequence provided on Annex C, to the appropriate Buyer the certificate or certificates evidencing the Equity Securities of the BV Companies to be sold by it at the Second Closing in accordance with Annex C, which certificates shall be duly endorsed for transfer or accompanied by duly executed stock transfer powers or other appropriate instruments of assignment and transfer in favor of the Buyer; (b) The Acquiror shall cause the Buyers to deliver or cause to be delivered to the Seller cash in the amount of the BV Preliminary Purchase Price Percentage times the Estimated Purchase Price. Such amount shall be paid in United States Dollars by wire transfer of immediately available funds to the wire transfer address of the Seller provided in written instructions by the Seller not less than three (3) Business Days prior to the Closing Date. (c) Any Intercompany Indebtedness owed at the Closing Date by any member of the Parent Group to any member of the BV Group or by any member of the BV Group to any member of the Parent Group shall be discharged, whether, at the election of the Parent (provided, that the Parent shall cooperate with the Acquiror to structure such discharge in the manner that is most tax-efficient to all the parties), by payment HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 7

by the obligor or by release and forgiveness by the obligee pursuant to a written release, in form and substance substantially similar to the form thereof attached hereto as Appendix II, executed and delivered at the Second Closing. The Intercompany Indebtedness has not been reflected in the Initial Balance Sheet, and will not be reflected in the Estimated or Closing Balance Sheet, as an asset or liability and, consequently, shall have no effect on the calculation of the Purchase Price Adjustment hereunder. (d) The Parent shall at the Second Closing execute, where appropriate, and deliver to the Acquiror, a release, in form and substance substantially similar to the form thereof attached hereto as Appendix III, by the Parent on behalf of itself and the Parent Group of all claims that they may have against any member of the BV Group with respect to the operation or conduct of the Businesses prior to the Closing Date. Section 2.08. Adjustment of the Preliminary Purchase Price. (a) By no later than five (5) Business Days after the delivery of a Closing Notice, the Parent shall deliver to the Acquiror on a consolidated basis, (i) the balance sheet of the Businesses as of December 31, 2000 and the related statement of results of operations for the twelve months then ended (the "Year-End Financial Statements") and (ii) the balance sheet (the "Estimated Balance Sheet") as of the close of business on the last day of the most recently completed calendar month for which internal management financial statements are available (the "Estimated Balance Sheet Date") and the related statement of results of operations of the Businesses for the period beginning on January 1, 2001 and ending on the Estimated Balance Sheet Date (together with the Estimated Balance Sheet, the "Estimated Financial Statements"). The Year End Financial Statements and the Estimated Financial Statements shall be prepared in accordance with U.S. GAAP applied consistently with the Initial Financial Statements. The Year End Financial Statements shall present fairly the financial position and the results of operations of the Businesses as of the date and for the period then ended and the Estimated Financial Statements shall, to the extent reasonably practicable in light of the purpose for which they were prepared and the time parameter provided in this subsection, present fairly the financial position and results of operations of the Businesses as of the date and for the period then ended. (b) The "Estimated Purchase Price" shall mean the Preliminary Purchase Price adjusted by the Estimated Purchase Price Adjustment. The Preliminary Purchase Price shall be increased by a positive Estimated Purchase Price Adjustment and decreased by a negative Estimated Purchase Price Adjustment. HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 8

(c) The "Estimated Purchase Price Adjustment" shall be an amount equal to the increase (positive) or decrease (negative) in the Net Equity as of the Initial Balance Sheet Date to the Estimated Balance Sheet Date, determined, in accordance with Section 2.10, by comparing the amount of Net Equity as of the Initial Balance Sheet Date with the amount of Net Equity as of the Estimated Balance Sheet Date; provided, however, that, if the amount of such Estimated Purchase Price Adjustment is less than U.S. $10,000,000 (ten million dollars), whether positive or negative, the Estimated Purchase Price Adjustment shall be deemed to be $0. (d) For purposes of the determination of the Estimated Purchase Price Adjustment and the Purchase Price Adjustment, Intercompany Indebtedness shall be classified and reflected in each of the Initial Balance Sheet, the Estimated Balance Sheet and the Closing Balance Sheet neither as an asset nor a liability. Section 2.09. Procedures for Calculating the Purchase Price Adjustment. (a) Following the end of the calendar month in which the First Closing shall occur, the Acquiror shall cause to be prepared and delivered to the Parent, no later than ninety (90) days following the end of such month, on a consolidated basis, the Closing Financial Statements, prepared in accordance with U.S. GAAP applied consistently with the Initial Financial Statements which shall be certified by Arthur Andersen LLP as presenting fairly the financial position of the Businesses as of the Closing Date. Thereafter, the Acquiror shall promptly provide to the Parent such supporting work papers or other supporting information as may be reasonably requested by the Parent, including access to the work papers of Arthur Andersen LLP prepared in connection with the audit of the Initial Financial Statements and the audit of the Closing Financial Statements. To the extent that the judgment of management of the Businesses is relied upon for any estimate used to prepare the Closing Balance Sheet as required or permitted by U.S. GAAP, such judgment shall not differ in any material respect from the judgment relied upon for the same or any similar estimate used to prepare the Initial Financial Statements unless there has been a material change since the date of the Initial Financial Statements in the facts upon which such judgment is based. (b) If the Parent shall have any objections to the Closing Balance Sheet, the Parent shall within twenty (20) Business Days following receipt of the Closing Balance Sheet so notify the Acquiror, stating in reasonable detail the basis for any such objections; provided, however, that the only bases for objection shall be (i) non-compliance with the standards set forth in subsection (a) of this Section for the preparation of the Closing Balance Sheet and (ii) computational errors. If the Parent fails to notify the Acquiror of any such objections in writing within such twenty (20) Business Day period, the Parent shall be deemed to have concurred with the Closing Balance Sheet. Otherwise, following any such notification, the Acquiror and the Parent shall endeavor in good faith for a period not to exceed twenty (20) Business Days to resolve their differences (the "Differences"). If the parties are unable to resolve all HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 9

their Differences and have not agreed in writing to extend the resolution period, either the Parent or the Acquiror shall, if the aggregate amount of the unresolved Differences does not exceed U.S. $10 million, be entitled for a period of twenty (20) additional Business Days to request the Accounting Firm to resolve the unresolved Differences or, if the aggregate amount of the unresolved Differences exceeds $10 million, to apply for arbitration pursuant to the provisions of Section 14.10. If the parties are unable to resolve all their Differences but neither party shall apply to the Accounting Firm or for arbitration for resolution of the remaining Differences, the determinations set forth in the Closing Balance Sheet, as adjusted for those Differences that the parties were able to resolve, shall be deemed to be dispositive. (c) If either party shall request the Accounting Firm to resolve the unresolved Differences, both parties shall cooperate with the Accounting Firm and its representatives by providing access to all relevant Books and Records and access at reasonable times to personnel having relevant information. The Accounting Firm shall be requested to use all reasonable efforts to resolve such Differences in favor of the Parent in their entirety or in favor of the Acquiror in their entirety within twenty (20) Business Days after the matter is referred to it on the basis of the standards set forth in subsection (a) of this Section or as soon thereafter as possible. Upon completion of its task, the Accounting Firm shall notify each party of its determination of the matters subject to the Differences, which determination shall be conclusive. The fees and expenses of the Accounting Firm shall be borne 50% by the Parent and 50% by the Acquiror. (d) If either party shall apply for arbitration to resolve the unresolved Differences, or if the Accounting Firm is unable to resolve the Differences, both parties shall cooperate with the arbitration tribunal and its representatives by providing access to all relevant Books and Records and access at reasonable times to personnel having relevant information. The arbitration tribunal shall be requested to use all reasonable efforts to resolve such Differences in favor of the Parent in their entirety or in favor of the Acquiror in their entirety within twenty (20) Business Days after the matter is referred to it on the basis of the standards set forth in subsection (a) of this Section or as soon thereafter as possible. The determination of the arbitration tribunal with respect to the Differences shall be conclusive. Unless differently awarded by the arbitration tribunal, the fees and expenses of arbitration shall be borne 50% by the Parent and 50% by the Acquiror. (e) The "Purchase Price Adjustment" shall mean an amount equal to the increase (positive) or decrease (negative) in the Net Equity of the Businesses from the Initial Balance Sheet Date to the Closing Date in accordance with Section 2.10, determined by comparing the amount of Net Equity as of the Initial Balance Sheet Date with the amount of Net Equity as of the Closing Date (based on the Closing Balance Sheet as finally determined pursuant to subsections (a) through (d) of this Section). HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 10

(f) The result obtained by subtracting the Estimated Purchase Price Adjustment from the Purchase Price Adjustment is referred to as the "Post-Closing Payment Amount." The Post-Closing Payment Amount shall be paid by the Acquiror to the Parent if it is positive or by the Parent to the Acquiror if it is negative, in cash in United States Dollars, by wire transfer of immediately available funds to the wire transfer address of the Acquiror provided in written instructions to the Parent or to the wire transfer address of the Parent provided in written instructions to the Acquiror, as appropriate, on the third (3rd) Business Day following the date on which the procedures in this Section 2.09 have been completed. The Post-Closing Payment Amount shall bear simple interest at the lowest interest rate applicable under the revolving credit agreement referred to in the Commitment Letter Term Sheets from the Closing Date to the date of such payment, inclusive. (g) If, notwithstanding the representations and warranties set forth in subsection (a) of Section 5.05 herein, it shall be determined that the Initial Financial Statements were not in fact prepared in accordance with U.S. GAAP, the Closing Financial Statements prepared pursuant to subsection (a) of Section 2.09 need not be prepared consistently with the Initial Financial Statements to the extent and only to the extent that such Initial Financial Statements were not prepared in accordance with U.S. GAAP. If the Closing Financial Statements are not prepared consistently with the Initial Financial Statements pursuant to this subsection (g) of Section 2.09 and such inconsistency results in a decrease in the amount of the Purchase Price Adjustment, any indemnification to be paid by the Parent to the Acquiror with respect to any such breach of the representations and warranties in Section 5.05 that caused the Purchase Price Adjustment shall be reduced by the amount of such decrease. Section 2.10. Adjustments to Net Equity. In determining the Estimated Purchase Price Adjustment and the Purchase Price Adjustment pursuant to Sections 2.08 and 2.09, the Net Equity reflected in the Initial Balance Sheet, the Estimated Balance Sheet and the Closing Balance Sheet shall be adjusted as follows: (a) Solely for the purpose of determining Net Equity in calculating the Estimated Purchase Price Adjustment and the Purchase Price Adjustment, the Net Equity reflected in each of such Balance Sheets shall be adjusted to exclude the following assets and liabilities in order that these assets and liabilities shall have no effect on the Estimated Purchase Price Adjustment or the Purchase Price Adjustment: (i) The Highway 6 Real Property; (ii) the accumulated projected benefit obligation for the postretirement medical and life benefits; (iii) assets transferred in excess of liabilities assumed of the DICON defined benefit retirement plan (Plan No. 164); (iv) reserves for uninsured litigation; and (v) the self-insurance reserves for workers' compensation, general liability, product liability and automobile liability. For the purpose of clarity of identification of the foregoing items, the amounts reflected on, or missing from, the Initial Balance Sheet for each of the above listed items is as follows: (A) Real Property subject to the Highway 6 Deed: $12.4 million, (B) the accumulated projected benefit obligation for the post-retirement medical and life HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 11

benefits: $128.3 million, (C) assets transferred in excess of liabilities assumed of the DICON defined benefit retirement plan (Plan No. 164): $9.0 million, (D) reserves for uninsured litigation: $10 million, and (E) the self-insurance reserves, including case reserves and IBNR, for workers' compensation, general liability, product liability and automobile liability: $21.7 million. (b) The Initial Balance Sheet includes an asset in the amount of $14,708,000 (fourteen million seven hundred and eight thousand dollars) representing the assets in excess of liabilities of the Dresser Canada Retirement Income Plan. This $14,708,000 asset is not an asset of a member of a Company Group and should not have been included in the Initial Financial Statements. In computing Net Equity at the Initial Balance Sheet Date, the Net Equity shall be reduced by $14,708,000, but this reduction shall not be made to the Net Equity to be determined as of either the Estimated Balance Sheet Date or the Closing Balance Sheet Date. The Parent shall not be entitled to make further adjustments to Net Equity reflected in the Initial Balance Sheet (other than those adjustments identified in this Agreement) after the date hereof. If it is determined by the Acquiror during the period from the date hereof to the date on which the Closing Balance Sheet is delivered to the Parent that any liabilities reflected in the Initial Balance Sheet are not liabilities of a member of a Company Group or that any assets of a member of a Company Group are not reflected in the Initial Balance Sheet, then the Net Equity determined by reference to the Initial Balance Sheet shall be increased to exclude such liabilities or to include such assets up to $14,780,000 in order that they shall have no effect on the Estimated Purchase Price Adjustment or the Purchase Price Adjustment. (c) No adjustments will be recorded in the Estimated Balance Sheet or the Closing Balance Sheet related to the allocation of the purchase price in connection with the acquisition of NIMCO. (d) Solelyfor the purpose of determining Net Equity in calculating the Estimated Purchase Price Adjustment and the Purchase Price Adjustment, cash and cash equivalents (net of the aggregate amount of (i) outstanding checks and overdrafts drawn on bank accounts of all members of the Company Groups and (ii) any notes payable by any member of either Company Group) ("Net Cash") shall be deemed to be $11.5 million on the Initial Balance Sheet notwithstanding the $23 million in Net Cash actually reflected in the Initial Balance Sheet. No adjustment shall be made to the actual Net Cash on the Estimated Balance Sheet or Closing Balance Sheet. (e) To the extent that Net Cash reflected in the Estimated Balance Sheet or Closing Balance Sheet exceeds $11.5 million in compliance with Section 11.03 (f), such excess will contribute positively to any Purchase Price Adjustment calculation to the benefit of the Parent. No other adjustments will be made to the Net Equity reflected in each of the Initial Balance Sheet, the Estimated Balance Sheet or the Closing Balance Sheet for the purpose of computing the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 12

Estimated Purchase Price Adjustments or the Purchase Price Adjustment. Accordingly, any changes in the amounts of other assets or liabilities reflected in the Estimated Balance Sheet or the Closing Balance Sheet as compared with the Initial Balance Sheet will have an effect on the Estimated Purchase Price Adjustment or the Purchase Price Adjustment or both. Section 2.11. Allocation of Purchase Price Adjustment. The Purchase Price Adjustment shall be allocated among Dresser Industries and the Seller in accordance with the Allocation Procedures of Annex D. Dresser Industries and the Seller shall be deemed to hold that portion of the Purchase Price Adjustment that it has theretofore received in constructive trust pending allocation of the entire Purchase Price Adjustment in accordance with such Allocation Procedures. Upon completion of the allocation, Dresser Industries and the Seller shall make such payments of cash in U.S. Dollars as shall be necessary to give effect to the allocation and the Parent shall, promptly after completion of the allocation, provide to the Acquiror a copy of the allocation, together with evidence, reasonably satisfactory to the Acquiror, of such payments. Section 2.12. Amendments to Effect Recapitalization. The parties acknowledge that certain amendments to the structure of the transactions contemplated hereby may be necessary in order to record such transactions as a Recapitalization for financial reporting purposes, as well as amendments to provide for the adjustment of the Purchase Price to account for the retention of equity by the Parent and the rollover of management equity, and the parties shall cooperate in good faith to effect such amendments. Section 2.13. Delayed Purchases. Notwithstanding any provisions to the contrary herein, (a) If at the time of the First Closing any of the Category 2A Requirements applicable to the First Closing shall not have been satisfied, the Acquiror may elect, in its sole discretion, to delay the purchase of the Equity Securities of the DEGI Group member located in such jurisdiction in which such Category 2A Requirements shall not have been satisfied until such time as such requirements have been satisfied; provided that the Acquiror shall have given written notice to the Parent of such election no later than ten (10) Business Days prior to the Closing Date. In such event, (i) prior to the First Closing, the Parent shall (A), if the assets subject to delayed purchase have not theretofore been transferred to the DEGI Group, cause a Retained Subsidiary to retain such assets or, if the assets subject to delayed purchase have theretofore been transferred to the DEGI Group, cause the appropriate member of the DEGI Group to transfer such Equity Securities to a member of the Parent Group; (ii) the Preliminary Purchase Price and the Merger Consideration shall be reduced by the dollar amount allocated to such Equity Securities on Schedule 2.13 to the Parent's Disclosure Letter; (iii) for any determination of Net Equity, the transfer of such Equity Securities pursuant to this subsection (a) shall be disregarded; and (iv) at the First Closing, the Acquiror shall execute and deliver to the Parent a Purchase and Sale Agreement, in form and substance substantially similar to the form thereof attached hereto as Appendix IX. HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 13

(b) If at the time of the Second Closing any of the Category 2A Requirements applicable to the Second Closing shall not have been satisfied, the Acquiror may elect, in its sole discretion, to delay the purchase of the Equity Securities of the BV Group member located in such jurisdiction in which such Category 2A Requirements shall not have been satisfied until such time as such requirements have been satisfied; provided that the Acquiror shall have given written notice to the Parent of such election no later than ten (10) Business Days prior to the Closing Date. In such event, (i) prior to the Second Closing, the Parent shall (A), if the assets subject to delayed purchase have not theretofore been transferred to the BV Group, cause a Retained Subsidiary to retain such assets or, if the assets subject to delayed purchase have theretofore been transferred to the BV Group, cause the appropriate member of the BV Group to transfer such Equity Securities to a member of the Parent Group; (ii) the Preliminary Purchase Price and the BV Consideration shall be reduced by the dollar amount allocated to such Equity Securities on Schedule 2.13 to the Parent's Disclosure Letter; (iii) for any determination of Net Equity, the transfer of such Equity Securities pursuant to this subsection (b) shall be disregarded; and (iv) at the Second Closing, the Acquiror shall execute and deliver to the Parent a Purchase and Sale Agreement, in form and substance substantially similar to the form thereof attached hereto as Appendix IX. (c) If the Equity Securities of any member of the DEGI Group or the BV Group are subject to delayed purchase pursuant to subsection (a) or (b) of this Section 2.13 and the operations of such member are conducted in more than one jurisdiction, the Parent and the Acquiror shall cooperate in amending Annex B to preserve the assets of such member that are located in any jurisdiction other than the Category 2A Jurisdiction resulting in the delayed purchase. Section 2.14. Joint Ventures. (a) If prior to the First Closing, a third Person has, with respect to its rights under any Contractual Transfer Restrictions relating to any DEGI Joint Venture, (i) (A) exercised a right to acquire the Equity Securities of the DEGI Joint Venture owned indirectly by DEGI (giving effect to the Reorganization), (B) failed to waive any such rights or (C) failed to provide a required consent and (ii) consummation of the transactions contemplated hereby would violate the terms of such Contractual Transfer Restriction, then (x) such DEGI Joint Venture shall be deemed not to be a member of the DEGI Group; (y) the Preliminary Purchase Price and the Merger Consideration shall be reduced by the dollar amount allocated to such DEGI Joint Venture on Schedule 2.14 to the Parent's Disclosure Letter; and (z) for any determination of Net Equity, such DEGI Joint Venture shall be disregarded. (b) If prior to the Second Closing, a third Person has, with respect to its rights under any Contractual Transfer Restrictions relating to any BV Joint Venture, (i) (A) exercised a right to acquire the Equity Securities of the BV Joint Venture owned indirectly by a BV Company (giving effect to the Reorganization), (B) failed to waive any such rights or (C) failed to provide a required consent and (ii) consummation of the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 14

transactions contemplated hereby would violate the terms of such Contractual Transfer Restriction, then (x) such BV Joint Venture shall be deemed not to be a member of the BV Group; (ii) the Preliminary Purchase Price and the BV Consideration shall be reduced by the dollar amount allocated to such BV Joint Venture on Schedule 2.14 to the Parent's Disclosure Letter; and (iii) for any determination of Net Equity, such BV Joint Venture shall be disregarded.

For a period commencing on the Closing Date and ending on the third anniversary of the Closing Date, the Parent, the Seller and their respective Subsidiaries (whether now existing or hereafter acquired or created and for so long as the Seller and such Subsidiaries remain as Subsidiaries of the Parent) shall not directly or indirectly engage in any geographical area in any business of the same type as that conducted by any of the Businesses as of the Closing Date in that geographical area (a "Competing Business"); provided, however, that the foregoing shall not prohibit (a) the ownership by the Parent, the Seller or any of their respective Subsidiaries (whether now existing or hereafter acquired or created) of less than 5% of the outstanding stock of any publicly-traded corporation engaged in a Competing Business, (b) activities HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 43

by the Parent, the Seller or their respective Affiliates that were existing activities of the Parent, the Seller or their respective Affiliates as of the Closing Date other than activities of the Businesses, (c) providing services similar to the services provided by the Businesses to only the Parent, the Seller and their Affiliates, provided, that the Parent and the Seller hereby represent that the Parent, the Seller or any Affiliate thereof does not, as of the date hereof or as of the Closing Date, have any current intention of providing any such services, (d) the acquisition of the Parent, the Seller or any of their Affiliates by a third party whose operations involve a Competing Business, (e) the acquisition by the Parent, the Seller or any of their Affiliates of a third party which engages in a Competing Business, provided that the primary purpose of any such acquisition referred to in this clause (e) is not the acquisition of such Competing Businesses, and provided further that such Competing Business referred to in this clause (e) either (i), together with the revenues for any prior acquisition exempted from the provisions of this Section 8.06 by this clause (e)(i), accounts for less than U.S. $50,000,000 in revenues for the last fiscal year of such third party for which financial statements are available or (ii) is divested by the Acquiror within 270 days from the date it is acquired or (f) the Parent or any of its Affiliates acquiring any Designated Regulatory Assets pursuant to subsection (a) of Section 8.05; provided, however, that if significant progress has been made and is continuing with respect to such divestiture by the end of such period, the period shall be extended at the request of the Parent for an additional ninety (90) days. If the final judgment of a Court of competent jurisdiction declares that any term or provision of this Section 8.06 is invalid or unenforceable, the parties agree that the Court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid and unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed. The Parent and the Seller acknowledge that the provisions of this Section 8.06 are reasonable in time and scope and necessary to protect the legitimate interests of the Acquiror and each Buyer and that any violation of this Section 8.06 will result in irreparable injury to the Acquiror, each Buyer and to the Businesses, the exact amount of which will be difficult to ascertain, and that the remedies at law for any such violation would not be reasonable or adequate compensation to the Acquiror, the Buyers and the Businesses. Accordingly, the Parent and the Seller agree that, if any of them or any of their Subsidiaries (whether now existing or hereafter acquired or created) violates this Section 8.06, the Acquiror, any of the Buyers and the members of each Company Group (following consummation of the transactions contemplated hereby) shall be entitled, in addition to any other remedy that may be available at law or in equity, to specific performance and injunctive relief, without posting bond or other security and without the necessity of proving actual damages. Section 8.07. Nonsolicitation. The Parent hereby covenants and agrees that, prior to the Closing Date, the Parent shall not and shall not permit the Seller or any member of either Company Group, (whether directly or indirectly through its officers, directors, advisors, agents or other intermediaries) to (i) solicit, initiate or take any action to facilitate the submission of inquiries, proposals or offers from any Person or group relating to (A) any acquisition or purchase of any portion of any Business or any Securities, (B) any merger, consolidation, recapitalization, sale of all or substantially all of the assets, liquidation, dissolution or similar transaction involving any member of either Company Group other than in connection with the Reorganization or transactions HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 44

contemplated by this Agreement or (C) any other transaction that, if agreed to by the Parent or any of its Subsidiaries, would contractually prohibit the Parent or the Seller from consummating all or any part of the transactions contemplated by this Agreement (each such transaction described in clauses (A), (B) and (C) being referred to herein as an "Acquisition Proposal"), or agree to or endorse any Acquisition Proposal, (ii) enter into or participate in any discussions or negotiations regarding any of the foregoing, or otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any other Person (other than any Buyer) to do or seek any of the foregoing. The Parent shall, and shall cause the Seller and each member of both Company Groups immediately (i) to cease and cause its officers, directors, advisors, agents and other intermediaries to cease any and all existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposal and (ii) to provide written notification to the Acquiror of any submissions, proposals, offers or inquiries relating to an Acquisition Proposal made prior to the Closing Date but shall not be required to disclose the contents of such proposal or the identity of the bidder. The Parent and the Seller hereby represent that they are not now engaged in discussions or negotiations with any party other than Acquiror with respect to any Acquisition Proposal.

Section 8.09. Financing. (a) Subject to subsection (b) of this Section 8.09, prior to the Closing Date, the Parent agrees to use all commercially reasonable efforts to provide, and to cause the Seller and each member of each Company Group, their advisers and the personnel of each member of each Company Group to provide, all necessary cooperation in connection with the arrangement of any financing that is to be consummated contemporaneously with the First Closing or within twelve months after the Closing Date in respect of the transactions contemplated by this Agreement, including participation in meetings, due diligence sessions, road shows, the preparation of offering memoranda, private placement memoranda, prospectuses and similar documents ("Offering Documents"), completion of a 2000 year-end audit, the execution and delivery of any commitment letters, underwriting or placement agreements, pledge and security documents, other definitive financing documents, or other requested certificates or documents, including a certificate of the chief financial officer of each member of HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 45

(b) The Acquiror agrees that it will provide the Parent with a reasonable opportunity to review each Offering Document and that it will not, and will cause its Affiliates and its and their agents, advisors, underwriters and placement agents to not, distribute such Offering Document to any investor or potential investor in any of the securities offered or to be offered pursuant to such Offering Document without obtaining the prior written approval of the Parent (which approval shall not be unreasonably withheld) of all information contained in such Offering Document that relates in any way to the Businesses. (c) The Parent shall cooperate and shall cause the Seller and each member of each Company Group to cooperate with any reasonable requests of the Acquiror or the SEC related to the recording of the transaction contemplated hereby as a Recapitalization for financial reporting purposes, including assisting the Acquiror and its Affiliates with any presentation to the SEC with regard to such recording. Unless otherwise required by Law or by any pronouncement of the SEC or by any authoritative accounting association after the Closing Date, the Parent agrees that it will not report the transaction contemplated hereby for financial accounting or other public disclosure purposes in a manner inconsistent with such recording. (d) The Acquiror agrees to reimburse the Parent promptly for all reasonable costs and expenses incurred by the Parent or any of its Affiliates in connection with the Parent's obligations under this Section 8.09.

To the extent that time does not permit proper recordation of such assignments, as for example in the case of certain assignments of Intellectual Property, the Parent shall cause the assignment of beneficial title to be effected prior to the Closings and, subsequent to the Closings, will provide such assistance and cooperation as necessary to effect recordable assignments of such assets. Section 8.12. Release of Liens.

(b) The Indemnifying Party shall, within thirty (30) days after receipt of an Indemnification Notice, either (i) in writing acknowledge liability, as between the Indemnifying Party and the Indemnified Party, for such Loss or the amount in controversy in such Proceeding and pay the Indemnified Party the amount of such Loss or the amount in controversy in such Proceeding in cash in immediately available funds (or establish by agreement with the Indemnified Party an alternative payment arrangement), (ii) in writing acknowledge liability, as between the Indemnifying Party and the Indemnified Party, for such Loss or the amount in controversy in such Proceeding but disavow the validity of the Loss or Proceeding or the amount thereof and, in the case of a Proceeding to the extent that it shall so desire in accordance with subsection (d) of this Section, assume the legal defense HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 68

thereof or (iii) in writing object (or reserve the right to object until additional information is obtained) to the claim for indemnification or the amount thereof and set forth the grounds therefor in reasonable detail. If the Indemnifying Party does not respond to the Indemnified Party as provided in this subsection within such thirty (30) day period, the Indemnifying Party shall be deemed to have acknowledged its liability for such indemnification claim in accordance with clause (i) of this subsection and the Indemnified Party may exercise any and all of its rights under applicable Law to collect such amount. (c) An Indemnifying Party shall not, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened Proceeding in respect of which indemnification or contribution is sought hereunder. If the Indemnifying Party has responded to the Indemnified Party pursuant to clause (i) of subsection (b) of this Section, the Indemnified Party may settle or compromise or consent to the entry of any judgment with respect to the Proceeding that was the subject of notice to the Indemnifying Party pursuant to subsection (b) of this Section without the consent of the Indemnifying Party (but no such settlement, compromise or consent shall increase the indemnification obligation of the Indemnifying Party to which it has consented pursuant to clause (i) of subsection (b) of this Section). Except as otherwise provided in the immediately preceding sentence and in subsection (d) of this Section, an Indemnified Party shall not, without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened Proceeding, but, if such Proceeding is settled or compromised or if there is entered any judgment with respect to any such Proceeding, in either case with the consent of the Indemnifying Party, or if there be a final judgment for the plaintiff in any such Proceeding, the Indemnifying Party shall indemnify and hold harmless any Indemnified Party from and against any Loss by reason of such settlement, compromise or judgment in accordance with the other provisions of this Article XII. (d) If a Proceeding shall be brought against an Indemnified Party and it shall notify the Indemnifying Party thereof in accordance with subsection (a) of this Section, the Indemnifying Party shall, if it shall have responded to such notice in accordance with clause (ii) of subsection (b) of this Section, be entitled to assume the legal defense thereof at the expense of the Indemnifying Party with counsel reasonably satisfactory to the Indemnified Party. The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) the employment of such counsel shall have been specifically authorized in writing by the Indemnifying Party or (ii) the Indemnifying Party shall have failed to assume the defense of such action or (iii) the named parties to any such Proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party shall have been advised by such HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 69

counsel that there is one or more legal defenses available to it that are different from or additional to those available to the Indemnifying Party. In any such case, the Indemnifying Party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the Indemnified Party. Except as aforesaid, after notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or such action, the Indemnifying Party shall not be liable to the Indemnified Party under this Section for any attorney's fees or other expenses (except reasonable costs of investigation) subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party does not assume the defense of a Proceeding as to which it has acknowledged liability, as between itself and the Indemnified Party, pursuant to clause (ii) of subsection (b) of this Section, the Indemnified Party may require the Indemnifying Party to reimburse it on a current basis for its reasonable expenses of investigation, reasonable attorney's fees and expenses and reasonable out-of-pocket expenses incurred in the defense thereof and the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party. (e) In the case of a Loss as to which the Indemnifying Party shall have responded pursuant to clause (iii) of subsection (b) above, the parties shall attempt in good faith to resolve their differences for a period of sixty (60) days following receipt by the Indemnified Party of the response of the Indemnifying Party pursuant to subsection (b) above and, if the parties are unable to resolve their differences within such period, the Indemnified Party may submit the matter to arbitration in accordance with the provisions of Section 14.10. Section 12.05. Special Environmental Indemnification Provisions. (a) The Parent shall have the sole and exclusive right to control the defense, response, proceedings, settlement and resolution of any Indemnifiable Environmental Matters, including any investigations, removals, remediations, response actions, enforcement actions or administrative proceedings; provided that the Parent shall not agree to any response, settlement or resolution that unreasonably interferes with any operations of the Business. The Acquiror shall cooperate in all reasonable ways with the Parent in the defense, contest, settlement of or prosecution of any Indemnifiable Environmental Matters. (b) With respect to any Indemnifiable Environmental Matters that require corrective actions, the Parent's indemnification obligations under clause (v) of subsection (a) of Section 12.02 shall be applicable to any investigation, removal, remediation or other response action ("Environmental Activities") only if and to the extent the conditions giving rise to such matter require reporting to a Governmental Authority and require corrective action under applicable Environmental Laws or, if such conditions were known to a Governmental Authority having jurisdiction over the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 70

matter, the Governmental Authority would be entitled to bring an enforcement action to require the Environmental Activities, but then only to the extent necessary to bring the appropriate member of a Company Group into compliance with the requirements of applicable Environmental Laws in effect as of the Closing Date. (The Acquiror shall be responsible for any additional Environmental Activities which may be required by Environmental Laws enacted or adopted after the Closing Date.) The Parent, in its sole discretion, shall determine the applicable cleanup standard for Covered Known Hazardous Materials Contamination and Unknown Hazardous Materials Contamination that are Indemnifiable Environmental Matters, in consultation with the Agency. Neither the Acquiror, any Buyer nor any member of a Company Group may use the properties of any member of any Company Group for any residential, health care, childcare or school purposes. The Acquiror acknowledges and agrees that any title transfer documents relating to the Real Property delivered to the Acquiror may contain restrictions on the use of the Real Properties. The Acquiror further agrees and binds itself to execute and file any and all documents restricting the use of the properties of the members of the Company Groups as may be required in connection with the Environmental Activities. Notwithstanding anything in this Section 12.05 to the contrary, no cleanup standards, use restrictions or institutional controls shall be required that unreasonably interfere with any operations of the Business. The Acquiror shall not encourage or invite any Agency to require any Environmental Activities or enforcement action; provided, however, that the Acquiror may cause the Buyers and the members of the Company Groups to comply with all applicable Environmental Laws in the use, ownership or occupation of the Real Property or the operations of the Businesses. (c) The Acquiror acknowledges that, prior to the Closing Date, the Parent may have initiated Environmental Activities as a result of the Parent's obligation to applicable Agencies, and that such Environmental Activities may continue after the Closing Date. The Acquiror further acknowledges that any Environmental Activities conducted after the Closing Date in accordance with this Section 12.05 or continued from Environmental Activities prior to the Closing Date may involve the filing of land use and deed restrictions, institutional and engineering controls, groundwater use restrictions, soil management requirements, access and easement rights, and restrictive covenants (including a prohibition against installation of water wells on the properties of the members of the Company Groups). The Acquiror shall at all times cooperate with the Parent in obtaining and maintaining any necessary documents, permits or conditions, and the Acquiror shall not take any action in contravention of such land use or deed restrictions or other requirements. The Acquiror further acknowledges that the Parent's environmental obligations hereunder may include sampling and excavating soil, the sampling, operation and maintenance of groundwater monitoring and recovery wells, associated piping, groundwater pumping and treatment equipment and other facilities or equipment. The Acquiror shall, without further compensation, costs or fees to the Parent, grant and provide, after reasonable advance notice, all necessary access to the Parent, the Parent's employees, agents, contractors, subcontractors, representatives and Agency HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 71

representatives to enter onto the properties of the members of the Company Groups after the Closing Date to undertake any Environmental Activities. The Parent's rights of access to use the properties of the members of the Company Groups are non-exclusive and shall endure as long as is necessary to complete the Environmental Activities. The Parent shall, to the extent practicable and consistent with sound investigation and remediation practices, undertake the Environmental Activities in a manner that will not unreasonably interfere with the use of the properties of the members of either of the Company Groups and shall indemnify and hold harmless the Acquiror against any Losses arising out of such rights of access except for any such Losses that arise out of or result from the negligence of the Acquiror or any Persons acting on its behalf. The Acquiror shall cause the Buyers and the members of the Company Groups to take all necessary precautions to avoid any damage to or loss of any equipment or facilities placed on the properties of the members of the Company Groups by the Parent as part of the Environmental Activities, and shall pay for all damages to or loss of such equipment or facilities resulting from any negligent acts or omissions of the Buyers or members of the Company Groups, or their ownership, use or occupancy of their properties. (d) The Parent's indemnity obligations with respect to Indemnifiable Environmental Matters under clause (v) of subsection (a) of Section 12.02 shall not apply to any Losses: (i) caused by the Acquiror's inspection of the properties of the members of the Company Groups; (ii) arising from the use or occupancy of the properties of the members of the Company Groups by the Acquiror or any of its Affiliates prior to the Closing Date; (iii) with respect to any Indemnified Environmental Matter known to Acquiror, arising from, caused by, or exacerbated by the use, occupancy or ownership of the Real Property or the operation of the Businesses or omissions of the Acquiror after the first anniversary of Acquiror gaining such knowledge, (iv) arising after the expiration of any applicable indemnity period, (v) based on Hazardous Materials Contamination, Environmental Compliance Matters or other conditions that did not exist as of the Closing Date; (vi) that constitute Known Hazardous Materials Contamination that is not Covered Known Hazardous Materials Contamination; (vii) incurred in connection with the management, removal or abatement of asbestos-containing material from any structure or equipment during any demolition or renovation of any facility or structure after the Closing Date; or (viii) arising from the migration of Hazardous Materials or Hazardous Materials Contamination onto the Real Property of any members of any of the Company Groups from an offsite source. The Parent, may at its own cost and option, participate in the defense of any such claim. (e) Except as set forth in this Article XII, the Acquiror unconditionally releases the Parent from any and all Losses arising out of or resulting from any Hazardous Materials or Hazardous Materials Contamination, Environmental Compliance Matters or related environmental conditions (including Known Hazardous Materials Contamination, Unknown Hazardous Materials Contamination Known Environmental Compliance Matters, Unknown Environmental Compliance Matters HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 72

and Indemnifiable Environmental Matters, regardless of how or when discovered). Provided that the Parent is in material compliance with its obligations under this Article XII, the Acquiror hereby covenants and agrees that neither the Acquiror nor any Affiliate under its control will file suit or name the Parent or any of its Affiliates in any lawsuit arising from any of the foregoing. The Acquiror understands and expressly agrees that releases set forth in this Section: (i) shall constitute releases of liability under all applicable Environmental Laws, including the United States Comprehensive Environmental Response, Compensation and Liability Act, as currently in effect, the United States Resource Conservation Recovery Act, as currently in effect, and any similar or equivalent laws in the jurisdiction of any Governmental Authority in which any properties of any member of a Company Group are located; (ii) shall constitute an assumption of future liabilities; (iii) are made with the knowledge of the prior commercial or industrial use of the properties of the members of the Company Groups and the possible presence of Hazardous Materials on such properties; and (iv) are supported by separate consideration, the receipt and sufficiency of which are expressly acknowledged and confessed by the Acquiror. Section 12.06. Punitive Damages. Neither party to this Agreement nor any of its Affiliates or Representatives shall be liable to any other party hereto or any of its Affiliates or Representatives for claims for punitive, special, exemplary or incidental damages, regardless of whether a claim is based on contract, tort (including negligence), strict liability, violation of any applicable deceptive trade practices act or similar Law or any other legal or equitable principle. No party shall be entitled to rescission of this Agreement as a result of breach of any other party's representations, warranties, covenants or agreements, or for any other matter. Section 12.07. Failure of Acquiror to Close. The Parent and the Acquiror have agreed that if the Acquiror shall fail to consummate the transactions contemplated hereby for any reason under its control that does not confer upon the Acquiror a right to terminate this Agreement under Section 13.01, the Acquiror shall pay to the Parent, on or before the fifth (5th) Business Day following the date on which the Acquiror failed to consummate such transactions in violation of the terms of this Agreement or, if such date is not determinable, the Termination Date, an amount in cash in U.S. Dollars equal to $20 million less professional fees and expenses incurred on behalf of the Acquiror prior to, on or after the date hereof by wire transfer of immediately available funds to the wire transfer address of Parent provided in written instructions to the Acquiror. Such amount shall be deemed to be liquidated damages and, in that regard, it is expressly stipulated by the parties that the actual amount of any damages resulting from the Acquiror's failure to complete the transactions contemplated by this Agreement would be difficult if not impossible to determine accurately because of the unique nature of this Agreement, the unique nature of the Securities, the uncertainties of the relevant markets in which the Businesses operate and differences of opinion with respect to such HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 73

matters, and that the liquidated damages provided for herein are a reasonable estimate by the parties of such damages. Section 12.08. No Right of Contribution. After the Closing Date, no member of either Company Group shall be obligated to indemnify either the Acquiror, any Buyer, the Parent or the Seller on account of the breach of any representation or warranty or the nonfulfillment of any covenant or agreement of the Parent or the Seller; and neither Parent nor the Seller shall have any right of contribution against any member of either Company Group for any such breach or nonfulfillment. Section 12.09. Specific Performance. The Parent hereby agrees that irreparable damage would occur to the Acquiror if the Parent failed to consummate the transactions contemplated hereby in accordance with the terms of this Agreement, and, accordingly, the Parent and the Acquiror agree that the Acquiror shall be entitled to enforce specifically the performance of the transactions contemplated hereby in the United States federal court for the Southern District of New York or in any other court having jurisdiction without posting bond or other security, this being in addition to any other remedy to which it is entitled at law or in equity. Section 12.10. Sole Remedy. From and after the Closing Date, the provisions of this Article XII shall, except as provided in subsection 2.09(g), be the sole and exclusive remedy of each party hereto for (i) any breach of the other party's representations or warranties contained in this Agreement or (ii) any breach of the other party's covenants or agreements contained in this Agreement (other than any covenant or agreement to be performed after the Closing Date). ARTICLE XIII TERMINATION, AMENDMENT AND WAIVER Section 13.01. Termination. This Agreement may be terminated at any time prior to the Closing Date: (a) by mutual written consent of the Parent and the Acquiror; (b) by the Parent, upon a breach of any representation, warranty, covenant or agreement on the part of the Acquiror set forth in this Agreement or if any representation or warranty of the Acquiror shall have become untrue, in either case, such that the conditions set forth in subsection (a) or (b) of Section 11.02 would not be satisfied (a "Terminating Acquiror Breach"); provided, however, that, if such Terminating Acquiror Breach is curable by the Acquiror through the exercise of its reasonable efforts and for so long as the Acquiror continues to exercise such reasonable efforts, the Parent may not terminate this Agreement under this subsection (b) until September 30, 2001; (c) by the Acquiror, upon a breach of any representation, warranty, covenant or agreement on the part of the Parent set forth in this Agreement or if any HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION 74

representation or warranty of the Parent shall have become untrue, in either case, such that the conditions set forth in subsection (a) or (b) of Section 11.03 would not be satisfied (a "Terminating Parent Breach"); provided, however, that, if such Terminating Parent Breach is curable by the Parent through the exercise of its reasonable efforts and for so long as the Parent continues to exercise such reasonable efforts, the Acquiror may not terminate this Agreement under this subsection (c) until September 30, 2001; (d) by either the Parent or the Acquiror, if the Closing Date contemplated hereby shall not have occurred on or before June 30, 2001 (the "Termination Date"); provided, however, that the right to terminate this Agreement under this subsection (d) shall not be available to either Party whose failure to fulfill any obligation under this Agreement has been, directly or indirectly, the cause of, or resulted in, the failure of the Closing Date to occur on or before such date; provided, further, that, if on the Termination Date the conditions to the First Closing set forth in subsection (b) or (c) of Section 11.01 shall not have been fulfilled but all other conditions to the First Closing have been fulfilled or are capable of being fulfilled, then the Termination Date shall be extended to September 30, 2001. The right of any party hereto to terminate this Agreement pursuant to this Section 13.01 shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any party hereto, any Person controlling any such party or any of their Representatives, whether prior to or after the execution of this Agreement. Section 13.02. Effect of Termination. If terminated pursuant to Section 13.01, this Agreement shall, except for Sections 9.01, 10.05, 10.07(a), 12.06, 12.07 and 12.09 of this Agreement, forthwith become void and (i) there shall be no liability on the part of the Parent, the Seller, the Acquiror or any of their respective officers or directors to any other party and (ii) all rights and obligations of any party hereto shall cease; provided, however, that nothing herein shall relieve the Parent, the Seller or the Acquiror from liability for any misrepresentation of any representation and warranty or breach of any covenant or agreement under this Agreement occurring prior to the date of such termination. Section 13.03. Amendment. This Agreement may not be amended except by an instrument in writing authorized by the Parent, the Seller and the Acquiror and signed by the Parent, the Seller and the Acquiror. Section 13.04.

The parties hereto agree and acknowledge that this covenant is ancillary to the Recapitalization Agreement, and is reasonably calculated to enforce covenants in the Recapitalization Agreement and this Agreement. 3.3 Exceptions. Notwithstanding the foregoing provisions of this Article 3, nothing in this Agreement shall prohibit: (a) the ownership by the ASSIGNEE or any of its Affiliates (whether now existing or hereafter acquired or created) of less than 5% of the outstanding stock of any publicly-traded corporation engaged in an Upstream Oilfield Business; (b) the acquisition of the ASSIGNEE or any of its Affiliates by a third party whose operations involve an Upstream Oilfield Business; (c) the acquisition by the ASSIGNEE or any of its Affiliates of a third party which engages in an Upstream Oilfield Business, provided that the primary purpose of any such acquisition referred to in this clause (c) is not the acquisition of such Upstream Oilfield Businesses, and provided further that such Upstream Oilfield Business referred to in this clause (c) either (i), together with the revenues for any prior acquisition exempted from the provisions of this Article 3 by this clause (c)(i), accounts for less than U.S. $50,000,000 in revenues for the last fiscal year of such third party for which financial statements are available or (ii) is divested by the ASSIGNEE or its Affiliate within 270 days from the date it is acquired; (d) any action of the Investor Group and investments of and other entities controlled by the Investor Group, individually or in the aggregate, other than with respect to Dresser, Inc. and its Subsidiaries; (e) any commercial relationship (as distinguished from an equity relationship) where ASSIGNEE sells services or products which are currently provided by ASSIGNOR or are logical extensions of such businesses as provided in the last proviso of Appendix B; or (f) any joint venture relationship in which (1) the joint venture does not use any Dresser name, (2) the ASSIGNEE has a minority equity interest, (3) the services or products provided by the ASSIGNEE to such joint venture are currently provided, serviced, sold or manufactured by ASSIGNEE or are logical extensions of such businesses as provided in the last proviso of Appendix B and (4) ASSIGNOR has a minority and non-controlling role in the management of such joint venture.

DAMAGE OR DESTRUCTION. A. Notice. If the building or other improvements situated on the Leased Premises should be damaged or destroyed by fire, tornado or other casualty, Tenant shall immediately give written notice thereof to Landlord. B. Partial Damage. If the building or other improvements situated on the Leased Premises are damaged by fire, tornado, or other casualty but not to such an extent that rebuilding or repairs cannot reasonably be completed within one hundred and twenty days (120) days from the date Landlord receives written notification by Tenant of the happening of the damage, this Lease Agreement shall not terminate, but Landlord shall proceed forthwith and use reasonable diligence to rebuild or repair such building and other improvements on the Leased Premises (other than leasehold improvements made by Tenant or any assignee, subtenant or other occupant of the Leased Premises) to substantially the same condition in which they existed prior to such damage. Landlord's obligation under this Section 20.B to use reasonable diligence to rebuild or repair such building and other improvements on the Leased Premises shall not exceed the proceeds received by Landlord from any insurance policy maintained by Landlord or Tenant under this Lease Agreement. If the casualty occurs during the final eight (8) months of the Lease Term, Landlord may elect not to rebuild or repair such HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX V-12

damage, provided the Tenant does not immediately elect to exercise its renewal option, if applicable. This Lease Agreement shall terminate upon Landlord's election and the Rent shall be abated for the remaining unused portion of this Lease Agreement, effective from the date of actual receipt by Landlord of the written notification of the damage. If the building and other improvements are to be rebuilt or repairs made which cause the Leased Premises to be untenantable in whole or in part following such damage, the installments of Rent payable hereunder during the period in which they are untenantable shall be adjusted equitably. C. Substantial or Total Destruction. If the Facility is substantially or totally destroyed by fire, tornado, or other casualty, or so damaged that rebuilding or repairs cannot reasonably be completed within one hundred twenty (120) days from the date Landlord receives written notification by Tenant of the happening of the damage, this Lease Agreement shall terminate at the option of either Landlord or Tenant and all future monthly installments of Rent shall be abated for the unexpired portion of this Lease Agreement. If this Lease Agreement is not terminated, the building and the improvements shall be rebuilt or repaired at Landlord's expense and the installments of Rent abated to the extent provided under Article 20.B hereof. Landlord's obligation to rebuild or repair under this Section 20.C shall not exceed the proceeds received by Landlord from any insurance policy maintained by Landlord or Tenant under this Lease Agreement. 21. CONDEMNATION. If there is any taking by eminent domain that materially affects Tenant's use of the Leased Premises, this Lease Agreement shall terminate when title vests in the authority exercising the right of eminent domain. The Rent shall be apportioned as of the day of termination, and any Rent paid for a period beyond that date shall be repaid to Tenant. Tenant shall not be entitled to any part of the award to Landlord for the taking but Tenant may file a claim for an award on Tenant's behalf. If there is a partial taking by eminent domain that does not materially affect Tenant's use of the Leased Premises, then there shall be no reduction of Rent payable by Tenant to Landlord, nor any right of termination by either party. 22. BANKRUPTCY OR INSOLVENCY. A. Neither this Lease Agreement nor any interest therein nor any estate thereby created, shall pass to any trustee or receiver in bankruptcy, or to any receiver or assignee for the benefit of creditors or otherwise by operation of law. B. In the event that the Tenant shall become bankrupt or shall make a voluntary assignment for benefit of creditors, or in the event that a receiver of the Tenant shall be appointed, then, at the option of the Landlord and upon fifteen (15) days written notice to the Tenant of the exercise of such option, this Lease Agreement shall cease and come to an end. 23. DEFAULT. A. Events of Default. If any Rent payable by Tenant shall be or remain unpaid for HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX V-13

more than ten (10) days after written notice from Landlord that same is due and payable, or if Tenant shall violate or make default in any of the other covenants, agreements, stipulations or conditions herein, and Tenant does not commence the correction of such default within twenty (20) days after receipt by Tenant from Landlord of written notice of such violation or default, stating the nature of such default, and thereafter continue the correction thereof with promptness and dispatch until the same is fully rectified, then it shall be optional for Landlord to terminate this Lease Agreement and receive from Tenant as damages for Tenant's breach, an amount equal to the discounted value of such Rents payable under the terms of this Lease Agreement for the residue of the term hereof, less the discounted value of the Rents to be received from the new Tenant or terminate Tenant's right of possession and to re-enter said Leased Premises, with or without process of law, using such force as may be necessary to remove all persons or chattels therefrom; but notwithstanding such re-entry by Landlord, the liability of Tenant for the Rent provided for herein shall not be relinquished or extinguished for the balance of the term of this Lease Agreement. B. Retaking. In the event Landlord terminates Tenant's right of possession under the terms and provisions of the previous paragraph and Landlord retakes the possession of the Leased Premises under the authority contained herein, all claims for damage incurred by reason of any such re-entry by Landlord are expressly waived by Tenant. It is further expressly understood and agreed that Landlord may resume possession of the Leased Premises and relet the same for the remainder of the term of this Lease Agreement on commercially reasonable terms for the account of Tenant, who shall make good any deficiency. Any such deficiency or part thereof may be recovered by Landlord from time to time from Tenant as such deficiency or part thereof is determined, or Landlord may elect to receive from Tenant as damages for Tenant's breach, an amount equal to the discounted value of such Rents payable under the terms of this Lease Agreement for the residue of the term hereof, less the discounted fair market rental value of the Leased Premises for the residue of the term hereof. The discount rate to be used for purposes of determining the discounted value of Rents and the discounted fair market rental value as provided in this Section 23 shall be a per annum rate equal to the "Prime Rate" as published on the date this Lease is terminated by The Wall Street Journal, Southwest Edition, in its listing of "Money Rates" minus one percent. C. Non-waiver. If Landlord should delay in enforcing any obligation of Tenant hereunder, or should waive the performance of any such obligation, or should accept payment of rent after the occurrence of any default by Tenant, then such action or forbearance by Landlord shall not be construed as a waiver of any default in any other obligation of Tenant hereunder, regardless of whether such default was then existing or had previously occurred or should thereafter occur. In the event Landlord employs an attorney to enforce any of its rights under this Lease Agreement, Tenant agrees to pay any reasonable attorney fees arising out of the enforcement of such rights. D. Tenant's Remedies. Landlord shall not be in default hereunder unless HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX V-14

Landlord fails to perform any of its obligations hereunder within thirty (30) days after written notice from Tenant specifying such failure (unless such performance will, when due to the nature of the obligation, require a period of time in excess of thirty (30) days, then after such period of time as is reasonably necessary). This shall not limit Tenant's rights to cure Landlord's default and offset Rent or to obtain an equitable abatement of Rent, all as otherwise expressly provided for in this Lease. All obligations of Landlord hereunder shall be construed as covenants, not conditions; and except as may be otherwise expressly provided in this Lease Agreement, Tenant may not terminate this Lease Agreement for breach of Landlord's obligations hereunder All obligations of Landlord under this Lease Agreement will be binding upon Landlord only during the period of ownership of the Leased Premises by Landlord and not thereafter. Any liability of Landlord under this Lease Agreement shall be limited solely to Landlord's interest in the Leased Premises, and in no event shall any personal liability be asserted against Landlord in connection with this Lease Agreement nor shall Tenant have any recourse against any other property or assets of Landlord. 24. TERMINATION AND RENTS. Notwithstanding anything to the contrary herein, the termination of this Lease Agreement for any reason shall not release Tenant from any liability to Landlord for Rents previously due and unpaid and shall not release Tenant from performance of any other obligation accrued prior to the time of such termination. 25. ASSIGNMENT AND SUBLETTING. Tenant shall not assign this Lease Agreement nor sublet the Leased Premises, in whole or in part, without the prior written consent of Landlord. Such consent by Landlord shall not be unreasonably withheld. Any assignment or subletting, even if consented to by Landlord, shall nevertheless be expressly subject to all of the terms, provisions and conditions of this Lease Agreement and shall not in any way release or impair the liabilities of Tenant hereunder. Notwithstanding the foregoing, Tenant may, without the prior written consent of Landlord, sublet the Leased Premises or any part thereof to an Affiliate, or assign this Lease Agreement to an Affiliate or permit occupancy of any portion of the Premises by an Affiliate. The term "Affiliate" shall mean (i) any corporation which, directly or indirectly, controls or is controlled by, or is under common control with Tenant; (ii) any corporation not less than fifty percent (50%) of whose outstanding stock shall, at the time be owned directly or indirectly by Tenant or Tenant's parent corporation; or (iii) any corporation that acquires all or substantially all of Tenant's assets. For purposes hereof, "control" shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such corporation, whether through the ownership of voting securities or by contract or otherwise. 26. QUIET ENJOYMENT. Landlord covenants, warrants and represents that it has full right and power to execute and perform this Lease Agreement, and to grant the estate demised herein, and that Tenant upon paying the Rent specified herein and performing the covenants and agreements contained herein, shall and may peaceably and quietly hold the Leased Premises for the term herein provided. 27.

Determination of the condition of the Premises prior to Tenant's move in and move out will be performed by visual inspection photographically recorded and agreed to by both Landlord and Tenant. 28. HOLDING OVER. In the event Tenant remains in possession of the Leased Premises after the expiration or termination of this Lease Agreement, for any reason, including to perform and complete any Remedial Work on the Leased Premises, such holding over shall not serve to renew or extend this Lease Agreement and Tenant shall be deemed to be occupying the Leased Premises as Landlord's Tenant from month to month subject to all of the conditions, provisions and obligations of this Lease Agreement insofar as the same are applicable to a month to month tenancy. The Rent for such holding over shall be paid within 10 days after demand, and be at the rate of One Hundred Fifty Percent (150%) of the prior Rent in effect at the termination of this Lease.

Dresser Industries, Inc. Union Plan (401(k)) (Plan No. 196). Effective immediately before the Effective Date, the members of the Parent Group shall withdraw from participation in and sponsorship of the foregoing plans and shall not be responsible for providing any benefits under such plans. For purposes of the Closing Balance Sheet, the Projected Benefit Obligation (the "PBO") calculated in accordance with United States Statement of Financial Accounting Standards No. 87 ("FAS 87") with respect to the plans listed in this Section 4.1 shall be determined using the same actuarial assumptions used for determining such obligation for the Initial Balance Sheet. Dresser hereby indemnifies and holds the members of the Parent Group and their ERISA Affiliates harmless from and against any and all damages, claims, liabilities or expenses arising from such plans. Section 4.2 Spin-off of Plan 164. Effective as of the Effective Date, Dresser shall cause to be established a defined benefit pension plan (the "Dresser Defined Benefit Plan") for the benefit of participants (including retired and deferred vested participants) in the Dresser Industries, Inc. Consolidated Salaried Retirement Plan (Plan No. 164) ("DICON") as of the Effective Date who are Continued Employees or whose employment prior to their retirement or termination of employment was in connection with the Businesses ("Former Business Employees") (including alternate payees related thereto) (such participants and alternate payees being hereinafter referred to as the "Transferred DICON Participants"). The Dresser Defined Benefit Plan shall have terms substantially similar to DICON as in effect immediately before the Effective Date, preserving all accrued benefits with respect to the Transferred DICON Participants. The Continued Employees shall be given credit in the Dresser Defined Benefit Plan for service with Dresser and its ERISA Affiliates for purposes of determining Vesting Service under the Dresser Defined Benefit Plan. In connection with the foregoing, the following actions will be taken: (i) At the time and in the manner set forth in paragraph (ii) below, the Parent shall cause to be transferred to the Dresser Defined Benefit Plan a pro-rata portion of the assets of DICON in an amount equal to the total assets of DICON as of the Effective Date multiplied by the accumulated benefit obligations with respect to the Transferred DICON Participants under DICON as of the Effective Date divided by the total accumulated benefit obligations with respect to all participants under DICON as of the Effective Date. (ii) The accumulated benefit obligations pursuant to paragraph (i) above shall be determined by Hewitt Associates in accordance with FAS 87 and based on the actuarial assumptions set forth on Schedule B attached hereto; provided, however, that the transfer pursuant to paragraph (i) above shall be subject to satisfaction of the requirements of section 414(l) of the Code and any other applicable governmental requirements as determined by Hewitt Associates and subject further to the review of such determinations by Dresser as set forth in Section 12.1. The transfer of assets will take place as soon as administratively practicable after the completion of the calculation and the obtaining of any required governmental approvals or otherwise complying with applicable governmental requirements. The amount transferred will be determined as of the Effective Date and will also include interest at seven percent HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-6

per annum from the Effective Date until the day immediately preceding the transfer. The assets will be transferred in cash (or other property reasonably acceptable to Dresser). (iii) Benefit payments to Transferred DICON Participants in pay status shall continue to be made from DICON following the Effective Date and until the date of the asset transfer described in paragraph (ii). Any such payments, adjusted for applicable interest, shall be deducted from the amount required to be transferred to the Dresser Defined Benefit Plan pursuant to paragraph (ii). (iv) Dresser agrees to apply for a favorable Internal Revenue Service determination letter as to the qualified status of the Dresser Defined Benefit Plan as soon as administratively practicable after the Effective Date. Dresser agrees to make any operational or form changes with respect to the Dresser Defined Benefit Plan as may be required by the Internal Revenue Service so that such a favorable determination letter will be issued. Following any such transfer of assets, Dresser shall assume all obligations and liabilities of the Parent Group under DICON with respect to the Transferred DICON Participants, and the Parent Group shall have no further liability to Dresser or any Transferred DICON Participant with respect thereto. Dresser hereby indemnifies and holds the members of the Parent Group and their ERISA Affiliates harmless from and against any and all damages, claims, liabilities, and expenses arising from DICON with respect to the Transferred DICON Participants. Section 4.3 Administration of Terminated Retirement Plan: Effective as of the Effective Date, Dresser shall assume all responsibilities for the administration of the group annuity contracts issued by The Prudential Insurance Company of America (the "Group Annuity Contracts") in connection with the termination of the Dresser Industries, Inc. Retirement Income Plan under ERISA, as constituted on April 1, 1986 ("Plan 19") with respect to those participants (including retired and deferred vested participants) who are Continued Employees or Former Business Employees (including alternate payees related thereto) (such participants being hereafter referred to as the "Transferred Plan 19 Participants"). Effective immediately before the Effective Date, the members of the Parent Group shall relinquish administration of the Group Annuity Contracts with respect to Transferred Plan 19 Participants and shall not be responsible for providing any such administration with respect to such contracts. Dresser hereby indemnifies and holds the Parent and its ERISA Affiliates harmless from and against any and all damages, claims, liabilities and expenses associated with the administration of the Group Annuity Contracts with respect to the Transferred Plan 19 Participants. Section 4.4 Spin-off of 401(k) Plan: (a) Effective as of the Effective Date, Dresser shall have in effect a tax-qualified defined contribution plan that includes a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code ("Dresser 401(k) Plan") and that provides terms that are identical to the Halliburton Retirement and Savings Plan (Plan No. 001) with respect to the pension equalizer HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-7

contribution formula thereunder as it applies to the Continued Employees who are entitled to such pension equalizer contribution immediately before the Effective Date, but taking into account any retirement benefits provided to the Continued Employees by any plan or program of Dresser after the Effective Date (the "Pension Equalizer") and shall maintain such terms with respect to the pension equalizer contribution formula without revision (provided, however, that if changes in the law require any such terms to be modified, such terms may be changed to comply with such laws). At such time after the Effective Date that the Parent is reasonably satisfied that the Dresser 401(k) Plan meets the requirements for qualification under Section 401(a) of the Code, the Parent shall cause to be transferred to the Dresser 401(k) Plan in a trust to trust transfer in cash (or other property reasonably acceptable to Dresser) assets equal to the value of the accounts (but not including assets reflecting any matching or other Parent contributions accrued but not yet contributed as of the Effective Date to the extent such contributions are accrued liabilities on the Closing Financial Statements) of the participants (including retired and deferred vested participants) in the Halliburton Retirement and Savings Plan (Plan No. 001) and the Halliburton Savings Plan (Plan No. 145) who are Continued Employees or Former Business Employees (including alternate payees related thereto) (such participants and alternate payees being hereinafter referred to as the "Transferred 401(k) Participants"); provided that any outstanding loans to Transferred 401(k) Participants from the Halliburton Retirement and Savings Plan (Plan No. 001) and the Halliburton Savings Plan (Plan No. 145) shall be transferred in kind. After the Effective Date and prior to any such transfer, Dresser and the Parent shall cooperate in the administration of distributions to and loan repayments from the Transferred 401(k) Participants. (b) Following any such transfer of assets, Dresser shall assume all obligations and liabilities of the Parent Group under the Halliburton Retirement and Savings Plan (Plan No. 001) and Halliburton Savings Plan (Plan No. 145) with respect to the Transferred 401(k) Participants, and the Parent Group shall have no further liability to Dresser or any Transferred 401(k) Participant with respect thereto. Dresser hereby indemnifies and holds the members of the Parent Group and their ERISA Affiliates harmless from and against any and all damages, claims, liabilities and expenses arising from the Halliburton Retirement and Savings Plan (Plan No. 001) and the Halliburton Savings Plan (Plan No. 145) with respect to the Transferred 401(k) Participants.

Dresser hereby indemnifies and holds the members of the Parent Group harmless from and against any and all damages, claims, liabilities and expenses arising from such plans. Section 5.2 Spin-off of Foreign Retirement Plans. Effective as of the Effective Date, Dresser shall cause to be established defined benefit pension plans ("Dresser Foreign Defined Benefit Plans") for the benefit of participants in the Dresser Canada Retirement Income Plan (the "Canadian Plan") and the Halliburton UK Pension Plan (collectively, the "Foreign Pension Plans") who are Continued Employees or Former Business Employees or any other individuals whose benefits are derived therefrom (the "Transferred Foreign Pension Plan Participants"). The Dresser Foreign Defined Benefit Plans shall have substantially similar terms as the Foreign Pension Plans HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-10

as in effect immediately before the Effective Date, preserving all accrued benefits with respect to the Transferred Foreign Pension Plan Participants. The Continued Employees shall be given credit in the relevant Dresser Foreign Defined Benefit Plan for service credited under the relevant Foreign Pension Plan for purposes of determining vesting service (and eligibility for other service-related ancillary benefits such as early retirement) under the Dresser Foreign Defined Benefit Plan. In connection with the foregoing, the following actions will be taken: (i) At the time, in the amounts, and in the manner set forth in paragraph (ii) below, the Parent shall cause assets from the Foreign Pension Plans to be transferred to the relevant Dresser Foreign Defined Benefit Plan as of the Effective Date. (ii) The amount of assets to be transferred shall be determined by the Parent's appointed actuary for each Foreign Pension Plan in accordance with local country law and practice but subject to the review of such determinations by Dresser as set forth in Section 12.1 and subject to the following provisions of this subparagraph 5.2(ii). (A) With respect to the Halliburton UK Pension Plan, to the extent permitted by local law or practice, the amount of assets to be transferred will be equal to the PBO calculated in accordance with FAS 87 using the assumptions described in Schedule C. To the extent that a payment in excess of such PBO is transferred pursuant to the requirements of local law or practice, the amount of such surplus shall be reflected on the Closing Balance Sheet. (B) With respect to the Canadian Plan, to the extent permitted by applicable Law, the amount of assets to be transferred will be a pro-rata portion of the assets of the Canadian Plan equal to the total assets of the Canadian Plan as of the Effective Date multiplied by the PBO with respect to the Transferred Foreign Pension Plan Participants under the Canadian Plan as of the Effective Date divided by the PBO with respect to all participants under the Canadian Plan as of the Effective Date. The PBO pursuant to the foregoing sentence will be determined in accordance with FAS 87 and based on the actuarial assumptions set forth on Schedule C attached hereto. To the extent that the amount of assets to be transferred pursuant to this paragraph 5.2(ii)(B) exceeds the PBO with respect to the Transferred Foreign Pension Plan Participants under the Canadian Plan calculated in accordance with this paragraph 5.2(ii)(B), the amount of such surplus shall be reflected on the Closing Balance Sheet. The transfer of assets will take place as soon as administratively practicable after the completion of the calculations and the obtaining of any required governmental approvals or otherwise complying with applicable governmental or other legal requirements. The amount transferred will be determined as of the Effective Date and will also include interest as set out in Schedule C from the Effective Date until the day immediately preceding the transfer. The assets will be transferred in cash (or HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-11

other property reasonably acceptable to Dresser). The Parent and Dresser agree to provide such data and information as necessary to assist the appointed actuary in the preparation of the calculation of the transfer amount and the filing of any governmental or other forms. (iii) Benefit payments to Transferred Foreign Pension Plan Participants shall continue to be made from the relevant Foreign Pension Plan following the Effective Date and until the date of the asset transfer described in paragraph (ii). Any such payments, adjusted for applicable interest, shall be deducted from the amount required to be transferred to the Dresser Foreign Defined Benefit Plans pursuant to paragraph (ii). Following any such transfer of assets, Dresser shall cause the Dresser Group to assume all obligations and liabilities of the Parent Group under the Foreign Pension Plans with respect to the Transferred Foreign Pension Plan Participants, and the Parent Group shall have no further liability to the Dresser Group or former Foreign Pension Plan participant with respect thereto. Dresser hereby indemnifies and holds the members of the Parent Group harmless from and against any and all damages, claims, liabilities and expenses arising from such plans with respect to the Transferred Foreign Pension Plan Participants.

The Dresser Nonqualified Plan(s) shall not be required to allow continued deferrals or accrual of benefits (other than earnings) thereunder. With respect to accrued liabilities assumed from the Dresser Industries, Inc. Deferred Compensation Plan, the Dresser Nonqualified Plan(s) shall convert valuations based on stock of the Parent to equivalent valuations based on stock of Dresser, or at Dresser's election, to a cash equivalent based on the valuation method set forth in Section VI. 1. of the Dresser Industries, Inc.

Dresser agrees to, and hereby does, indemnify and hold the Parent Group harmless from and against any liabilities, costs, damages, claims or expenses with respect to (x) any and all matters and any and all actions taken in connection with any liabilities assumed pursuant to the foregoing provisions of this Section 7.1, (y) Parent's liability with respect to any and all restricted stock awards or any and all cash payments in connection with restricted stock awards that are assumed by Dresser pursuant to this Section 7.1, and (z) the establishment and operation of any deferred compensation plan(s) by Dresser in connection with this Section 7.1, including but not limited to the content and distribution of election forms and summary descriptions of any such plans and compliance with any and all applicable Laws and any tax consequences with respect to such plans and deferral elections thereunder.

elect, by written notice to the Parent no later than March 31, 2001, that the liability for the payments under any or all of the Retention Agreements shall be assumed by Dresser, and Dresser shall create one or more nonqualified deferred compensation plans which shall reflect such assumed liabilities as book reserves hypothetically invested as either (a) units of "phantom equity" of Dresser or (b) cash earning interest at a rate determined by Dresser in its discretion. Dresser agrees to, and hereby does, indemnify and hold the Parent Group harmless from and against any liabilities, costs, damages, claims or expenses with respect to (x) any and all matters and any and all actions taken in connection with any liabilities assumed pursuant to the foregoing provisions of this Article VIII, (y) Parent's liability with respect to any and all payments under the Retention Agreements that are assumed by Dresser hereunder, and (z) the establishment and operation of any deferred compensation plan(s) by Dresser in connection with this Article VIII, including but not limited to the content and distribution of election forms and summary descriptions of any such plans and compliance with any and all applicable Laws and any tax consequences with respect to such plans and deferral elections thereunder. ARTICLE IX EMPLOYMENT OBLIGATIONS Except as otherwise provided herein, effective as of the Effective Date, Dresser shall cause the Dresser Group to assume all liability and responsibility for all obligations connected with employment of the Continued Employees and with respect to the Former Business Employees, including, but not limited to, social security, retirement/termination indemnities, and participation in mandated employee benefit plans (whether due to Law or collective bargaining or similar agreement) without regard to when such obligations were incurred. Dresser hereby indemnifies and holds the members of the Parent Group harmless from and against any and all claims or liabilities arising from such employment obligations. ARTICLE X APPLICATION TO SUBSEQUENT PURCHASERS In the event that any other business entity (regardless of its relationship to the Dresser Group) acquires all or a portion of a member of a Company Group (whether as a stock purchase or asset purchase), (a) Dresser will require any such entity (i) to maintain the benefits described in Section 3.2 and to maintain a defined contribution plan which provides the Pension Equalizer to those Transferred 401(k) Participants who are eligible to participate in the Pension Equalizer immediately before the Effective Date, (ii) to provide indemnities identical to those set forth in Sections 3.2 and 4.4 herein in favor of Dresser, and (iii) to require any and all successor entities to comply with the foregoing clauses (i) and (ii) in the event any other business entity subsequently acquires all or a portion of such member of the Company Group.

Promptly after the Effective Date, in addition to any other actions required to be taken by the Parent under this Employee Benefits Agreement, the Parent shall furnish Dresser with any and all data, reports, compilations, calculations, and working papers not then in the possession of Dresser that relate to the benefit liabilities that are being assumed by the Dresser Group hereunder and that are reasonably necessary to enable the Dresser Group to fulfill any and all obligations they have assumed under this Employee Benefits Agreement. ARTICLE XII DISPUTED CALCULATIONS Section 12.1 Calculation of DICON and Foreign Pension Plan Spin-Offs. The calculations contemplated in Sections 4.2 and 5.2 shall first be made by the Parent's actuary. The Parent shall provide a copy of such calculations to Dresser's actuary promptly upon completion thereof along with such other information as such Dresser's actuary may reasonably request, which information shall be true and correct in all material respects. If Dresser's actuary concludes that the calculations made by the Parent's actuary are incorrect or inconsistent with Sections 4.2 or 5.2, as applicable, the parties shall seek to resolve the difference among themselves or, if they are unable to do so, shall resolve such matter in accordance with the procedure set forth in Section 12.3. Section 12.2 Calculations of Assumed Retiree Benefits. In the event an error in the Census Data (as defined below) with respect to the retiree medical and retiree life benefits assumed by Dresser pursuant to Section 3.2 is discovered by the Parent or Dresser (collectively, the "Contracting Parties") or any affiliate or any agent (including an actuary or actuaries) of any of the Contracting Parties prior to the six month anniversary of the Effective Date, such Contracting Party has the obligation to notify the Parent and Dresser of such error in the Census Data in writing within 30 days of the six month anniversary of the Effective Date in accordance with the notice provisions of Section 14.01 of the Recapitalization Agreement. If the actuary or actuaries of any Contracting Party determine that the Cumulative Effect of all errors in Census Data discovered prior to the six month anniversary of the Effective Date nets to $500,000 or more, such Contracting Party shall supply all Contracting Parties with such determination, along with such other information as any Contracting Party shall reasonably request, within 60 days following the six month anniversary of the Effective Date and the Affected Party (as defined below) shall have 30 days to review such determination. In the event the Affected Party disputes such determination, any such dispute shall be resolved between the Parent and Dresser, or if they are unable to do so, such dispute shall be resolved according to Section 12.3, with the 30 day period referred to in Section 12.3(a) commencing on the date the Affected Party receives such determination. In the event the Cumulative Effect (as defined below) of all errors in Census Data is determined under the foregoing HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-15

provisions to exceed $500,000 (a) if such Cumulative Effect is a net decrease in liability, Dresser shall pay to Parent the amount of any such net decrease in liability and (b) if such Cumulative Effect is a net increase in liability, the Parent shall pay to Dresser the amount of any such net increase in liability. Any such payment shall be made within 30 days that the amount of such Cumulative Effect is finally determined pursuant to this Section 12.2 and pursuant to Section 12.3, if applicable. For purposes of this Section 12.2 the following terms shall have the following meanings: (i) "Affected Party" shall mean the Parent or Dresser, as applicable, to whom another Contracting Party has provided an actuarial determination pursuant to this Section 12.2 that would require a payment from such party pursuant to this Section. (ii) "Census Data" shall mean the following basic demographic information with respect to Continued Employees, Prior Retirees and their eligible dependents (according to the status of such individuals as eligible dependents as of May 1, 2000) (hereinafter "Assumed Retirees"): identification of such individuals, date of birth, date of hire, gender, amount of life insurance coverage in effect on May 1, 2000, the benefit and level of retiree medical coverage elected on May 1, 2000 (if applicable), and with respect to individuals who as of May 1, 2000, were not yet eligible for retiree medical or retiree life insurance benefits, the identification of which programs and benefits such individuals may become eligible for as of May 1, 2000. Any change effective after May 1, 2000, in the following information shall not be considered to be an error in census data for purposes of this Employee Benefits Agreement: (i) changes in coverage elections, (ii) eligible dependent status, (iii) available coverages, and (iv) accrual of service and normal aging from and after May 1, 2000. (iii) "Cumulative Effect" shall mean (A) the net aggregate effect of each error in Census Data on the total liability for retiree medical and retiree life with respect to Assumed Retirees calculated as of May 1, 2000; provided, however, for these purposes such liability shall be the Accumulated Post Retirement Benefit Obligation (APBO) as described in Statement of Financial Accounting Standards No. 106 as of May 1, 2000, as calculated by Hewitt Associates using the same actuarial assumptions and methods as used to determine the APBO as reflected in the Initial Financial Statements, multiplied by (B) a factor of 1.21. Section 12.3 Resolution of Disputes With Respect to Calculations. (a) If the parties do not reach a final resolution within 30 days following the date the Parent has provided the calculations to Dresser's actuary under Section 12.1 or within 30 days following the date an Affected party has received a "determination" from a Contracting Party under Section 12.2, as applicable, unless the parties mutually agree to continue their efforts to resolve such differences, an actuary selected jointly by the Parent's actuary and Dresser's actuary (or, if such actuaries HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VI-16

are unable to jointly agree on such an actuary, an arbitrator selected by the New York, NY office of the American Arbitration Association (the "Arbitrator")) shall resolve such differences in the manner provided below. The Parent and Dresser shall each be entitled to make a presentation to the Arbitrator, pursuant to procedures agreed to among the Parent, Dresser and the Arbitrator, advocating the merits of the calculations espoused by such party, and the Arbitrator shall be required to resolve the differences between the parties and determine the appropriate calculations within ten business days thereafter. Such determination shall be conclusive and binding upon such parties, absent fraud or manifest error. (b) Nothing herein shall be construed to authorize or permit the Arbitrator to determine any questions or matters whatsoever under or in connection with this Employee Benefits Agreement except for resolution of difference between the parties regarding the calculations set forth in this Article XII.

(b) If either party hereto can identify a third party service provider who agrees to provide a Service to the Service Receiver at a lower cost than that specified in the Service Level Specifications for such Service, then the Service Receiver shall have the right to request the Service Provider to reduce its cost to an amount equal to the cost offered by the third party.

(e) From time to time after the date hereof, the parties may identify additional services that Halliburton or the Company heretofore provided to the other. At the request of the other party, Halliburton or the Company, at its sole option, may decide to provide such services to the other party.

If such consents are not obtained, then Halliburton or the Company, as appropriate, shall use its commercially reasonable efforts to assist the other party in obtaining these services directly from the Vendor. 2. Billing and Payment. Within fifteen (15) days after the end of each month, the Service Receiver shall remit to the Service Provider, by wire transfer to an account specified by the Service Provider, the fees specified in the Service Level Specifications, other than any fees or expenses required to be paid directly to third parties pursuant to subsection 8(b).

NOW, THEREFORE, in consideration of the foregoing recitals, the mutual promises hereinafter set forth, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. CONFLICTS. 1.1 Potential Conflicts. Each Stockholder and the Company acknowledges that: (a) The Control Stockholder or one or more subsidiaries (other than the Company and its subsidiaries) or other affiliates or members of the Control Stockholder (other than the Company, its subsidiaries and their respective officers and directors not nominated, directly or indirectly, by the Control Stockholder) (the Control Stockholder and any such subsidiary or affiliate being collectively referred to herein as an "Interested Party") may engage in material business transactions with the Company, subject to the provisions of Section 1.6 herein. (b) Directors, officers, and employees of an Interested Party may serve as directors or officers of the Company. (c) One or more Interested Parties may now or in the future engage in the same or similar lines of business or other business activities as those in which the Company may engage. (d) One or more Interested Parties may exercise a controlling influence over business, policy and strategic decisions of the Company. 1.2. Scope of Business of the Company and its Controlled Affiliates. The Company hereby renounces any interest or expectancy in any business opportunity that does not consist exclusively of a portion or all of the Designated Business. For this purpose, the Designated Business consists of the businesses conducted by the Company and its controlled affiliates as described in that certain Offering Memorandum dated April 4, 2001 prepared and distributed by the Company. 1.3 Corporate Opportunities. The Company and each Stockholder recognize that the Interested Parties and individuals who are directors, officers and employees of one or more Interested Parties and are designated by the Interested Parties to serve as directors and officers of the Company and its controlled affiliates ("Designees") (a) participate and will continue to participate, directly and through affiliates, in businesses that compete with, or are substantially the same as, the Designated Business, (b) may have interests in, participate with, and serve as directors, officers or employees of other persons engaged in businesses that compete with, or are substantially the same as, the Designated Business and (c) may develop business opportunities for the Interested Parties. The Company and each Stockholder (i) acknowledge and agree that neither the Interested Parties nor their Designees shall be restricted or prohibited by the relationship between the Interested Parties and the Designees, on the one hand, and the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-2

Company, on the other, or by service of a Designee as a director or officer of the Company from engaging in any businesses that compete with, or are substantially the same as, the Designated Business or in any other business, regardless of whether such business activity is in direct or indirect competition with the Designated Business of the Company, (ii) acknowledge and agree that, as long as their activities are conducted in accordance with the standards set forth in Section 1.4 hereof, neither any Interested Party nor any Designee shall have any obligation to offer the Company or any of its controlled affiliates any business opportunity, (iii) renounce any interest or expectancy in any business opportunity pursued by any Interested Party in accordance with the standards set forth in Section 1.4 hereof and (iv) waive any claim that any business opportunity pursued by an Interested Party or any Designee in accordance with the standards set forth in Section 1.4 hereof constitutes a corporate opportunity of the Company or any of its controlled affiliates that should have been presented to the Company. 1.4 Standards for Separate Conduct of Business. The Interested Parties and their Designees shall be deemed to meet the standards set forth in this Section 1.4 if the business of the Interested Parties is conducted through the use of their own personnel and assets and not with the substantial involvement of any personnel (other than the Designees) or material amount of assets of the Company. Without limiting the foregoing, such standards will be met with respect to a business opportunity if (a) it is identified by or presented to personnel of an Interested Party or a Designee and developed and pursued substantially through the use of the personnel (including any Designee) and assets of one or more Interested Parties (and not based on confidential information disclosed by or on behalf of the Company in or during the course of a Designee's relationship with the Company), and (b) it did not come to the attention of such Designee solely in, and as a direct result of, his or her capacity as a director or officer of the Company; provided, however, that (i) if such opportunity is separately identified by an Interested Party or separately presented to an Interested Party other than such Designee, the Interested Parties shall be free to pursue such opportunity even if it also came to the Designee's attention solely as a result of and in his or her capacity as a director or officer of the Company and (ii) if such opportunity is presented to or identified by a Designee other than solely as a result of and in his or her capacity as a director or officer of the Company, the Interested Parties shall be free to pursue such opportunity even if it also came to the Designee's attention as a result of and in his or her capacity as a director or officer of the Company. Nothing in this Agreement shall be interpreted to allow a Designee to pursue a business opportunity in the Designated Business solely for his or her personal benefit (as opposed to the benefit of an Interested Party). 1.5 Competing Activities. Except as otherwise expressly provided in an agreement between the Company and an Interested Party, any Interested Party and its officers, directors, agents, shareholders, members, partners, affiliates and subsidiaries, may engage or invest independently or with others, in any business activity of any type or description, including without limitation those that might be the same as or similar to the Designated Business and without limiting the foregoing, the Stockholders acknowledge that: (a) (i) First Reserve Corporation, a Delaware corporation ("First Reserve" or "FRC"), manages each of First Reserve Fund VIII, L.P., a Delaware limited HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-3

In addition to the foregoing, (i) if all of the transactions entered into after the date hereof among the Company or its subsidiaries, on the one hand, and with First Reserve and its affiliates (the "FRC Affiliate Group"), on the other hand, (other than the acquisition by the Company of Entech Industries, Inc., a Delaware corporation, and LVF Holding Corporation, a Delaware corporation, both of which are controlled by First Reserve) in the aggregate exceed $50 million, then the Company will not enter into any subsequent transactions with the FRC Affiliate Group unless the Company obtains a resolution of the Board of Directors of the Company approved by a majority of Disinterested Directors certifying as to the fairness of the transaction, and (ii) if all of the transactions entered into after the date hereof among the Company or its subsidiaries, on the one hand, and with Odyssey and its affiliates (the "Odyssey Affiliate Group"), on the other hand, in the aggregate exceed $50 million, then the Company will not enter into any subsequent transactions with the Odyssey Affiliate Group unless the Company obtains a resolution of the Board of Directors of the Company approved by a majority of Disinterested Directors (which majority shall include the affirmative vote of at least one director appointed by FRC) certifying as to the fairness of the transaction.

No other shares may be included (other than by the Company or by the Holders pursuant to Section 2.3) without the Requesting Stockholder's consent. (c) Maximum Number of Demand Registrations. The Company shall be obligated to effect only one (1) such registration pursuant to this Section 2.2 for DI, and the Company shall be obligated to effect only six (6) such registrations pursuant to this Section 2.2 for the Control Stockholder; provided, however, that, if the number of Registrable Securities that the Requesting Stockholder is permitted to offer under this Section 2.2 is reduced by more than 50% of the amount such Requesting Stockholder requested to be registered in the Initial Demand Notice as a result of the application of Section 2.2(b), the initial request shall not reduce the number of requests permitted by this Section 2.2(c) pursuant to Section 2.2(a). A Registration shall be effected for purposes of this Section 2.2(c) when and if a registration statement is declared effective by the Commission and the distribution of securities thereunder has been completed without the occurrence of any stop order or proceeding relating thereto suspending the effectiveness of the Registration. (d) Deferral. Notwithstanding the foregoing, if the Company shall furnish to the Requesting Stockholder a certificate signed by the President or Chief Executive Officer of the Company stating that, in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such registration statement then to be filed, the Company shall have the right to defer such filings and, by notice to the Requesting Stockholder, to require the Requesting Stockholder to withdraw its Demand Notice and to refrain from delivering another Demand Notice for a period of not more than ninety (90) days after receipt of the request of the initial Demand Notice; provided, however, that the Company may not utilize this right more than twice in any twelve (12) month period. (e) Expenses. All expenses incurred in connection with any registration pursuant to this Section 2.2, including without limitation all federal and "blue sky" registration, filing and qualification fees, printer's and accounting fees, fees and disbursements of counsel for the Company, and fees and expenses of one counsel to the Holders (selected by the Holder including Registrable Securities in such registration statement that holds the greatest number of Registrable Securities) shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.2 shall, in the case of a firmly underwritten offering, bear such Holder's proportionate share (based on the total number of shares sold in such registration HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-7

other than for the account of the Company) of all discounts, commissions or other amounts payable to underwriters in connection with such offering by the Holders and, in the case of any other offering, bear the entire amount of discounts, commissions and other amounts payable to underwriters or brokers attributable to Registrable Securities sold by such Holder pursuant to such registration. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 2.2 if the registration request is subsequently withdrawn at the request of the Requesting Stockholder, unless the Requesting Stockholder agrees that such registration constitutes the use by it of one (1) demand registration pursuant to this Section 2.2; provided, however, that, if at the time of such withdrawal, the Requesting Stockholder has learned of a material adverse change in the condition, business, or prospects of the Company not known to the Requesting Stockholder at the time of its request for such registration and has withdrawn its request for registration with reasonable promptness after learning of such material adverse change, then the Requesting Stockholder shall not be required to pay any of such expenses and such registration shall not constitute the use of a demand registration pursuant to this Section 2.2. 2.3 Piggyback Registrations. The Company shall promptly notify all Holders of Registrable Securities in writing (a "Piggyback Notice") prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, without limitation, registration statements relating to secondary offerings of securities of the Company, whether pursuant to Section 2.2 or otherwise, but excluding registration statements relating to any employee benefit plan, an acquisition or a corporate reorganization) and will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by such Holder shall within ten (10) days after receipt of the Piggyback Notice, so notify the Company in writing and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such registration statement. (a) Underwriting. If a registration statement referred to in the Piggyback Notice is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in such a Registration pursuant to this Section 2.3 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting as provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting. With respect to the Company's Initial Public Offering or any other offering in which the Company is registering securities, all Holders, whether or not they are participating in such offering, hereby agree not to effect any sale, transfer, assignment, pledge or conveyance of (including, without limitation, taking any short position in) the Common Stock (or any securities of the Company exchangeable or convertible into Common Stock) during (i) the 90-day period beginning on the effective date of a registration statement filed by the Company (except as part of that Registration), or (ii) any period in which trading in the Company's securities is restricted HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-8

pursuant to Company insider trading policies; provided, however, that none of DI, FRC or Odyssey shall be subject to the restrictions imposed by clause (ii) of this Section during any period in which it has not designated any of the directors of the Company and is otherwise not affiliated with the Company. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities that would otherwise be registered and underwritten pursuant hereto, and the managing underwriter(s) may exclude shares of the Registrable Securities from the registration and the underwriting, and the number of shares that will be included in the registration and the underwriting shall be allocated as set forth in Section 2.2, or, if the underwriting is not pursuant to Section 2.2, first to the Company, and second, to each of the Holders requesting inclusion of their Registrable Securities in such registration statement on a pro rata basis based on the total number of Registrable Securities requested for inclusion in the registration by each such Holder. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter(s), delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration. For both (i) any Holder that is a partnership, the Holder and the partners and retired partners of such Holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons, and (ii) any Holder that is a corporation, the Holder and all corporations that are affiliates of such Holder, shall be deemed to be a single "Holder," and any pro rata reduction with respect to such "Holder" shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such "Holder," as defined in this sentence. (b) Expenses. All expenses incurred in connection with a registration pursuant to this Section 2.3 (excluding underwriters' and brokers' discounts and commissions relating to shares sold by the Holders, which shall be borne by each Holder of such shares), including without limitation all federal and "blue sky" registration, filing and qualification fees, printers' and accounting fees, fees and disbursements of one counsel for Holders (selected by the Holder including Registrable Securities in such registration statement that holds the greatest number of Registrable Securities), and fees and disbursements of counsel for the Company, shall be borne by the Company. (c) Not Demand Registration. Registration pursuant to this Section 2.3 shall not be deemed to be a demand registration as described in Section 2.2, unless the Requesting Stockholder specifically elects otherwise in writing. Except as otherwise provided herein, there shall be no limit on the number of times the Holders may request registration of Registrable Securities under this Section 2.3. 2.4 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities under this Agreement the Company shall, as expeditiously as reasonably possible: HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-9

(a) Registration Statement. 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 to keep any such registration statement effective for so long as required by the Securities Act to complete the distribution. (b) Amendments and Supplements. 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 Securities Act with respect to the disposition of all securities covered by such registration statement. (c) Prospectuses. Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration. (d) Blue Sky. 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 the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions. (e) Underwriting. In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement in usual and customary form (including indemnification provisions), with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. (f) Notification. 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 Securities 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. (g) Opinion and Comfort Letter. Furnish, at the request of any Holder requesting registration of Registrable Securities or of any underwriter in connection herewith, on the date or dates requested by such Holder, (i) an opinion, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a "comfort" letter dated as of such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-10

underwriters in an underwritten public offering and reasonably satisfactory to a majority in interest of the Holders requesting registration, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. (h) Road Shows. To the extent reasonably requested by a Requesting Stockholder, cause the appropriate members of the management and employees to participate in meetings, diligence sessions, and road shows. 2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to Sections 2.2 or 2.3 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them, and the intended method of disposition of such securities as shall be required to effect timely the Registration of their Registrable Securities. 2.6 Indemnification. If any Registrable Securities are included in a registration statement under Sections 2.2 or 2.3: (a) By the Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, officers and directors of each Holder, any underwriter (as defined in Section 2(11) of the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended, (the "Exchange Act"), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities 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 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 or final prospectus contained therein or any amendments or supplements thereto; (ii) any omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any federal or state securities law in connection with the offering covered by such registration statement; and the Company will reimburse each such Holder, partner, officer or director, underwriter or controlling person for any legal or other expenses reasonably incurred by them, as incurred, in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 2.6(a) shall not HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-11

apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent (and only to the extent) that it arises out of or is based upon a Violation that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, officer, director, underwriter or controlling person of such Holder. (b) By Selling Holders. To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder's partners, directors or officers or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, partner or director, officer or controlling person of such other Holder may become subject under the Securities 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 reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action: provided, however, that the indemnity agreement contained in this subsection 2.6(b) 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 the Holder, which consent shall not be unreasonably withheld; and provided, further, that the total amounts payable in indemnity by a Holder under this Section 2.6(b) in respect of any Violation shall not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises. (c) Notice. Promptly after receipt by an indemnified party under this Section 2.6 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 2.6, 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 notified, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-12

within a reasonable time of the commencement of any such action shall relieve such indemnifying party of liability to the indemnified party under this Section 2.6 only to the extent the indemnifying party is prejudiced as a result thereof, and 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 2.6. (d) Defect Eliminated in Final Prospectus. The foregoing indemnity agreements of the Company and Holders are subject to the condition that, insofar as they relate to any Violation made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement in question becomes effective or the amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final Prospectus"), such indemnity agreement shall not inure to the benefit of any person if a copy of the Final Prospectus was timely furnished to the indemnified party and was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act. (e) Contribution. To provide for just and equitable contribution, if an indemnified party makes a claim for indemnification pursuant to Section 2.6 (subject to the limitations hereof) but it is found in a final judicial determination, not subject to further appeal, that such indemnification may not be enforced in such case, even though this Agreement expressly provides for indemnification in such case, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Stockholders from the offering of the Registrable Securities or (ii) if the allocation provided in clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and Stockholders in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Stockholders shall be deemed to be in the same proportion as the total net proceeds from the offering and sale of the Registrable Securities (before deducting expenses) received by the Company and the Stockholders, bears to the total price to the public of the Registrable Securities. The relative fault of the Company and the Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or the alleged omission to state a material fact relates to information supplied by the Company or the Stockholders and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.6(e) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-13

reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 2.6, no Stockholder shall be required to contribute more in the aggregate than the aggregate net proceeds received by such Stockholder in the registered offering out of which such contribution obligation arises. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (f) Survival. The obligations of the Company and Holders under this Section 2.6 shall survive until the first anniversary of the expiration of all applicable statutes of limitation or extensions of such statutes. 2.7 Termination of the Company's Obligations. The Company shall have no obligations pursuant to Sections 2.2 or 2.3 with respect to any Registrable Securities proposed to be sold by a Holder in a registration pursuant to Section 2.2 or 2.3 if, in the reasonable opinion of counsel to the Company, addressed to such Holder, all such Registrable Securities held by such Holder could be sold in a single transaction in reliance upon Rule 144 promulgated under the Securities Act. 3. SALES BY STOCKHOLDERS. 3.1 Restrictions on Transfer; Notice of Sales. (a) Absolute Restriction. Except for Permitted Transfers (as defined in Section 3.6) and transfers effected in accordance with Section 3.5 (provided that, in the case of such transfer effected in accordance with Section 3.5, DI shall have a co-sale right pursuant to Section 3.3), no Stockholder shall sell, transfer, assign, pledge or otherwise dispose of, directly or indirectly, through the sale of interests in any holding company or otherwise ("Transfer") any shares of the capital stock of the Company now held or hereafter acquired by such Stockholder ("Stock") prior to April 10, 2003. (b) Sale Only In Accordance With This Section. No Stockholder shall Transfer any shares of Stock, other than by means of a Permitted Transfer (as defined in Section 3.5) or a Transfer effected in accordance with Section 3.2, Section 3.3, Section 3.4, Section 3.5 or Section 4, during the period beginning on April 10, 2003 and ending on the day prior to the effective date of the registration statement pertaining to the Company's Initial Public Offering. If any Stockholder (the "Seller") proposes to Transfer any Stock, then the Seller shall promptly give written notice (the "Notice") to the Company and the other Stockholders at least thirty-five (35) business days prior to the closing of such sale or transfer (or, in the case of a Transfer pursuant to Section 3.2, forty-five (45) days). In addition to any requirements of Section 3.2, the Notice shall describe in reasonable detail the proposed sale or transfer including, without limitation, the number of shares of Stock to be sold or transferred, the nature of such sale or HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-14

transfer, the consideration to be paid, and, if known, the name and address of each prospective purchaser or transferee. 3.2 Right of First Refusal. (a) At least forty-five (45) days prior to DI making any Transfer (other than a Permitted Transfer), either directly or indirectly, of any shares of the Company's capital stock (such shares, the "Offer Shares"), DI shall deliver the Notice to the Company and the other Stockholders. (b) Upon receipt of the Notice, the Company may elect to purchase all (or a portion) of the Offer Shares specified in the Notice at the price and on the terms specified therein by delivering written notice of such election to DI and the other Stockholders within ten (10) days after the delivery of the Notice. If the Company has not elected to purchase all of the Offer Shares within such ten-day period, the other Stockholders may elect to purchase their pro rata share of the available Offer Shares (which shall be the same as the number contained in the Notice less any such Offer Shares the Company has elected to purchase) at the price and on the terms specified therein by delivering written notice of such election to the Company and DI within twenty (20) days after delivery of the Notice. Any Offer Shares not elected to be purchased by the end of such 20-day period shall be reoffered for the ten-day period prior to the expiration of the Notice by DI on a pro rata basis to the Stockholders who have elected to purchase their pro rata share. If the Company or any other Stockholders have elected to purchase all of the Offer Shares from DI, the transfer of such shares shall be consummated within fifteen (15) days after the expiration of the initial 30-day period. If the Company and the other Stockholders have not elected to purchase all of the Offer Shares being offered, then neither the Company nor the other Stockholders may purchase any of the Offer Shares and DI may transfer all of the Offer Shares to one or more third parties at a price not less than the price per share specified in the Notice and on other terms no more favorable to the transferees than offered to the Company and the Stockholders in the Notice. The purchase price specified in any Notice shall be payable solely in cash at the closing of the transaction or in installments over time, and no capital stock of the Company held by a Holder may be pledged except on terms and conditions satisfactory to a majority in interest of the Stockholders. (c) The right of first refusal established by this Section 3.2 shall terminate on the effective date of the registration statement pertaining to the Company's Initial Public Offering. 3.3 Co-Sale Right. (a) If any Seller holding more than 5% of the outstanding Common Stock (or equivalent) of the Company desires to Transfer Stock (other than a Permitted Transfer), then such Seller shall deliver the Notice to all of the Stockholders. Each Stockholder shall have the pro rata right, based on the total number of shares of Common Stock held by such Stockholder, exercisable upon written notice to the Seller within fifteen (15) days after receipt of the Notice, HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-15

to participate in such Transfer of Stock on the same terms and conditions, up to the total number of shares of Stock included in the Notice. To the extent Stockholders exercise such right of participation (each a "Co-Sale Stockholder") the number of shares of Stock that the Seller may sell or otherwise dispose of in the Transfer shall be correspondingly reduced so that the maximum number of shares of Stock sold or otherwise disposed of in the Transfer by the Seller or a Co-Sale Stockholder under this Section 3.3 shall be the number found by multiplying the total number of shares included in the Notice, as delivered under this Section 3.3, by a fraction the numerator of which is the total number of shares owned by the Seller or such Co-Sale Stockholder, as the case may be (on a fully diluted basis) and the denominator of which is the total number of shares owned by the Seller and all Co-Sale Stockholders exercising such rights in the aggregate (on a fully diluted basis). Each Co-Sale Stockholder shall effect its participation in the Transfer by promptly delivering to Seller for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, that represent the number of shares of Stock which such Co-Sale Stockholder elects to sell. The Seller will use its best efforts to obtain the agreement of the prospective transferee(s) to the participation of the Co-Sale Stockholders in the contemplated Transfer and will not Transfer any Stock to the prospective transferee(s) if such transferee(s) refuses to allow the participation of the Co-Sale Stockholders, or refuses to become a party to this Agreement as a Stockholder. (b) The co-sale right established by this Section 3.3 shall terminate upon the effective date of the registration statement pertaining to the Company's Initial Public Offering. In addition, notwithstanding anything in Section 3.3(a) to the contrary, no Employee Stockholder shall have any rights under Section 3.3 with respect to any sale or transfer by DI. 3.4 Further Sales. To the extent the Company, the Control Stockholder and the other Stockholders do not exercise their rights under Sections 3.2, or 3.3 with respect to the sale of Stock subject to the Notice, the Seller may, not later than one hundred twenty (120) days following the first delivery to the Company and the other Stockholders of the Notice, conclude a Transfer of the Stock covered by the Notice and (i) in the case of Section 3.2, not elected to be purchased by the Company or the Stockholders on terms and conditions no less favorable to the Seller than those described in the Notice or (ii) in the case of Section 3.3, not excluded from the Transfer by virtue of the participation therein by Co-Sale Stockholders on the terms and conditions set forth in the Notice. Any proposed Transfer on terms and conditions less favorable to the Seller than those described in the Notice (in the case of a Transfer subject to Section 3.2) or more favorable to the Seller than those described in the Notice (in the case of a Transfer subject to Section 3.3) or any proposed transfer of any Stock by the Seller after such one hundred twenty day period, shall again be subject to the co-sale rights and rights of first refusal of the Stockholders and shall require compliance by the Seller with the procedures described in this Section 3. Notwithstanding the foregoing, no Transfer of the Stock shall be effective unless such transferee agrees to be bound by the terms of this Agreement as a Stockholder. 3.5 Rights to Compel Transfer. HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-16

(a) If a Stockholder or Stockholders or any of their affiliates holding, individually or collectively, more than 50% of the outstanding Stock (collectively, the "selling Stockholder"), proposes to make a Transfer to any person or entity (other than the Control Stockholder) that, (i) upon completion of such Transfer, would hold, directly or indirectly, more than 50% of the outstanding Stock on a fully diluted basis and (ii) is not an affiliate of such Stockholder, then such Stockholder shall have the right, exercisable as set forth below, to require all of the other Stockholders (the "Remaining Stockholders") to sell, directly or indirectly, any or all of the Common Stock (as well as, at the election of the selling Stockholder, any securities convertible into or exercisable for Common Stock, and any other equity interest of the Company (the "Stock Rights")) then owned by such Remaining Stockholders (the "Transfer Stock") to the proposed transferee (the "Acquiror") in the same pro rata amount (determined based upon the relative direct or indirect ownership of shares of Common Stock) as is being sold by the selling Stockholder and for the same consideration per share of Common Stock as is being paid to the selling Stockholder and on the same terms as are applicable to the selling Stockholder (the "Compelled Transfer"). The purchase price for each vested Stock Right in any such Transfer shall equal the "spread" between the exercise price for such vested Stock Right and the purchase price per share of Stock. The terms and conditions of the Compelled Transfer shall be as set forth in the applicable purchase agreement between the selling Stockholder and the Acquiror. (b) The selling Stockholder shall cause the terms of the Compelled Transfer to be reduced to writing and shall provide a written notice (the "Compelled Transfer Notice") of such Compelled Transfer to the Company and the Company shall provide such Compelled Transfer Notice to the Remaining Stockholders. The Compelled Transfer Notice shall contain written notice of the exercise of the selling Stockholder's rights pursuant to Section 3.5(a) hereof, setting forth the consideration to be paid by the Acquiror for each share of Stock and each Stock Right and the other terms and conditions of the Compelled Transfer. Within 20 calendar days following the date of receipt of the Compelled Transfer Notice, each of the Remaining Stockholders shall deliver to the selling Stockholder certificates representing the Stock required to be transferred and instruments representing Stock Rights required to be transferred, duly endorsed, together with all other documents required to be executed in connection with such Compelled Transfer or, if such delivery is not permitted by applicable law, an unconditional agreement to deliver such certificates pursuant to this Section 3.5(b) at the closing for such Compelled Transfer against delivery to such Remaining Stockholder of the consideration therefore. Such certificates shall be held by the selling Stockholder in escrow for the benefit of the appropriate Remaining Stockholder. If a Remaining Stockholder should fail to deliver such certificates as described herein, the Company shall cause the books and records of the Company to show that such Stock and Stock Rights are bound by the provisions of this Section 3.5(b) and that such Stock and Stock Rights shall be transferred only to the Acquiror upon surrender for Transfer by the Remaining Stockholder thereof. (c) If, within 150 calendar days (or such longer period not exceeding 210 calendar days as may be necessary to comply with any applicable provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or to obtain other required regulatory approval) after the selling Stockholder gives the Compelled Transfer Notice, they have not HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-17

completed the sale of all the Transfer Stock, the selling Stockholder shall return to each of the Remaining Stockholders all certificates representing Stock and instruments representing Stock Rights that such Remaining Stockholders delivered for sale pursuant hereto, and all the restrictions on sale or other disposition contained in this Agreement with respect to such Stock and the Stock owned by the selling Stockholder shall again be in effect. (d) Upon the consummation of the Compelled Transfer, the selling Stockholder shall give notice thereof to the Remaining Stockholders, and shall (or shall cause the Acquiror to) remit promptly to each of the Remaining Stockholders a net amount with respect to the Stock and Stock Rights of such Remaining Stockholders sold pursuant thereto, after deducting a pro rata portion of any related out-of-pocket fees and expenses, and shall furnish such other evidence of the completion and time of completion of such sale or other disposition and the terms thereof as may be reasonably requested by such Remaining Stockholders. (e) The right to compel Transfers established by this Section 3.5 shall terminate upon the effective date of the registration statement pertaining to the Company's Initial Public Offering. 3.6 Permitted Transfers. The following shall be considered "Permitted Transfers," and not subject to the restrictions of this Section 3, provided the transferee thereof (the "Permitted Transferee") agrees to become a party to and be bound by the provisions of this Agreement as a Stockholder: (a) Transfers to the Company approved in advance by the Board, (b) Transfers among the members of the Control Stockholder and from the Control Stockholder to its members, (c) Transfers by DI to affiliates of DI, (d) Transfers by an Employee Stockholder to another Employee Stockholder with the approval of the Board, (e) Transfers or gifts by Employee Stockholders for bona fide estate planning purposes, (f) Transfers effected pursuant to an effective registration statement filed pursuant to the Securities Act, or (g) after the Company's Initial Public Offering, Transfers of securities registered under the Exchange Act sold in reliance upon an exemption under the Securities Act. 4. REPURCHASE OF SHARES AND RIGHT TO PUT SHARES TO THE COMPANY. 4.1 Right to Put Shares to the Company Upon Termination of Employment. Each Employee Stockholder has the right to cause the Company to purchase all or part of the shares of Stock (but not Stock Rights) of the Company held by such Employee stockholder (the "Put Shares") at the Repurchase Price (as such term is defined in Section 4.4) (the "Put Right") pursuant to the terms set forth in the "Executive Employment Agreement" entered into between each Employee Stockholder and the Company. If a Terminated Stockholder (as hereinafter defined) elects to exercise his/her Put Right, the Terminated Stockholder shall deliver written notice of such intention to the Company (the "Put Notice") on or prior to the date that is nine months following the date on which the Terminated Stockholder's employment with the Company was terminated (such nine-month period shall be the "Put Period"). Upon delivery of the Put Notice, the Terminated Stockholder shall immediately transfer and deliver to the HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-18

Company the number of Put Shares specified in the Put Notice, and the Company shall, so long as and to the extent permitted by the financing agreements of the Company, pay the Repurchase Price for such Put Shares in cash in immediately available funds within ten (10) business days of delivery of the Put Notice. The purchase of the Put Shares shall be deemed to have occurred upon delivery of the Repurchase Price, notwithstanding any failure by the Terminated Stockholder to deliver share certificates representing the Put Shares or any dispute regarding the Repurchase Price. Notwithstanding anything herein or in an Executive Employment Agreement to the contrary, the Company shall not be obligated to purchase any Stock of an Employee Stockholder that has not been held by such Employee Stockholder for a period of at least six months. Any Stock underlying a Stock Right shall not be deemed to be "held" until the full purchase price therefore has been paid to the Company. For purposes of this Section 4, a "Terminated Stockholder" shall mean any Employee Stockholder upon the termination of employment or consulting relationship of such Stockholder. 4.2 Optional Repurchase Upon Termination of Employment. Each Employee Stockholder agrees that the Company shall have the right (but not the obligation, other than as set forth in Section 4.1 and any Executive Employment Agreement) to repurchase all or part of the shares of Stock or vested Stock Rights of the Company held by such Employee Stockholder (the "Repurchase Shares") at the Repurchase Price upon the termination of employment or consulting relationship of such Stockholder, after giving effect to the operation of Section 4.1. 4.3 Procedure for Repurchase. If the Company elects to purchase the Repurchase Shares, and to the extent such Repurchase Shares have not yet been repurchased pursuant to Section 4.1, the Company shall deliver written notice of such intention to the Terminated Stockholder on or prior to the last day of the first full calendar month following the expiration of the Put Period (without giving effect to any waiver of the Put Period prior thereto) (the "Notice of Repurchase"). Upon delivery of the Notice of Repurchase, the Terminated Stockholder shall immediately transfer and deliver to the Company the number of Repurchase Shares specified in the Notice of Repurchase, and the Company shall pay the Repurchase Price for such Repurchase Shares in cash in immediately available funds within six months of delivery of the Notice of Repurchase. The purchase of the Repurchase Shares shall be deemed to have occurred upon delivery of the Repurchase Price, notwithstanding any failure by the Terminated Stockholder to deliver share certificates representing the Repurchase Shares or any dispute regarding the Repurchase Price. 4.4 Repurchase Price. The "Repurchase Price" for Repurchase Shares or Put Shares shall be the fair market value of the Repurchase Shares or the Put Shares, as the case may be, as determined in the good faith judgment of the Board, provided, however that the Repurchase Price for Stock Rights shall be the fair market value of the shares underlying the Stock Rights less any applicable exercise price. The fair market value shall be determined using the same method of valuation that First Reserve Fund IX, L.P. uses for purposes of reporting to its limited partners, with appropriate discount applied to Put or Repurchase Shares or shares underlying Stock Rights representing a minority ownership position. The Board shall determine fair market value as of the last day of the month in which the employment of the Terminated Stockholder is HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-19

terminated. Notwithstanding the foregoing, if the Company's right to repurchase shares under this Section 4 arises as a result of the termination of employment of the Terminated Stockholder described in Section 3.4 of the Executive Employment Agreement of such Terminated Stockholder, then the Repurchase Price shall be determined without regard to any discount attributable to minority ownership. 4.5 Disputes as to Repurchase Price. In the event of any dispute regarding the Repurchase Price, the Terminated Stockholder will irrevocably transfer the Put and/or Repurchase Shares to the Company as set forth in Sections 4.1 and 4.3 above and the Company shall pay the Repurchase Price for the Put or Repurchase Shares (as determined by the Board) within ten (10) business days of the Put Notice or the Notice of Repurchase (as the case may be). In such event, the Terminated Stockholder may elect to use an investment bank selected by the Board to determine the Repurchase Price. If the Repurchase Price as finally determined by such investment bank is less than 115% of the Repurchase Price determined by the Board, the Terminated Stockholder shall pay the fees of such investment bank. The Company or the Terminated Stockholder, as the case may be, shall pay the difference between the value determined by the Board and the value finally determined by the investment bank. 4.6 Unvested Stock Rights. Any unvested Stock Right shall not be repurchased pursuant to this Section 4 (except as may be required pursuant to an Executive Employment Agreement), and shall terminate as set forth in the respective agreements granting such right. 5. ASSIGNMENT, AMENDMENT AND TERMINATION. 5.1 Assignment. (a) General. Notwithstanding anything herein to the contrary, the rights of a Stockholder hereunder may be assigned in connection with any Transfer in accordance with this Agreement; provided, however, that no party may be assigned any of the foregoing rights and no Transfer shall be permitted unless (i) the Company is given written notice by the assigning party at the time of such assignment stating the name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned and (ii) any such assignee shall have agreed to be subject to all the terms and conditions of this Agreement, including without limitation the provisions of this Section 5. (b) Repurchase Rights. The Company may assign its rights under Section 4 to the Control Stockholder. 5.2 Amendment of Rights; Termination. (a) Amendment. Subject to Section 7.10, any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively) with the written consent of Stockholders holding not less than sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX VIII-20

Common Stock subject to this Agreement held by Stockholders (not on a fully diluted basis). Any amendment or waiver effected in accordance with this Section 5.2 shall be binding upon the Stockholders, each Holder, each permitted successor or assignee of such Stockholder or Holder and the Company. In addition, Employee Stockholders holding a majority of shares of Common Stock (on a fully diluted basis) held by Employee Stockholders may amend or waive any provision of this Agreement on behalf of all Employee Stockholders ("Employee Stockholder Approval"). In addition, this Agreement may be amended in any manner by the Control Stockholder and the Company in connection with a reorganization or recapitalization in which members of the Control Stockholder become stockholders of the Company, provided such amendment does not materially and adversely effect any of the other parties hereto. Notwithstanding the foregoing, no amendment or waiver shall be effective as to an Employee Stockholder unless (a) there is Employee Stockholder Approval, or (b) such amendment or waiver does not disproportionately and adversely affect such Employee Stockholder or the Employee Stockholders as a group. (b) Termination. This Agreement may be terminated with the written consent of the Stockholders holding not less than sixty-six and two-thirds percent (66 2/3%) of the shares of Common Stock subject to this Agreement; provided such consent must include the consent of DI at any time prior to the Initial Public Offering, or so long as they own at least 1% of the outstanding shares. Notwithstanding the foregoing, this Agreement may not be terminated as to Employee Stockholders in connection with a transaction that would give Employee Stockholders rights under Section 3 or 4 of this Agreement without Employee Stockholder Approval. 6.

Each certificate representing shares of capital stock of the Company now or hereafter owned by a Stockholder shall be endorsed with the following legend: THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAWS OF ANY STATE.

Appendix X FORM OPINION OF COUNSEL TO THE ACQUIROR Ladies and Gentlemen: We have acted as counsel to DEG Acquisitions, LLC, a Delaware limited liability company (the "Acquiror"), and DEG Acquisition Corporation, a Delaware corporation (the "Merger Sub"), in connection with the recapitalization of Dresser, Inc., a Delaware corporation ("Dresser"), pursuant to that certain Amended and Restated Agreement and Plan of Recapitalization, dated April 10, 2001 ("the Agreement") between Halliburton Company (the "Parent"), the Seller party thereto and the Acquiror (the "Transaction"). This opinion is rendered to you pursuant to Section 11.02(e) of the Agreement. Capitalized terms used but not defined herein shall have the meanings given them in the Agreement. As such counsel, we have made such legal and factual examinations and inquiries as we have deemed necessary or appropriate for purposes of this opinion. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies. As to facts material to the opinions, statements and assumptions expressed herein, we have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others. In addition, we have obtained and relied upon such certificates and assurances from public officials as we have deemed necessary. Whenever a statement herein is qualified by "to the best of our knowledge" or a similar phrase, it is intended to indicate that those attorneys in this firm who have rendered legal services in connection with the Transaction do not have current actual knowledge of the inaccuracy of such statement. However, except as otherwise expressly indicated, we have not undertaken any independent investigation to determine the accuracy of any such statement. We have examined, among other things, the following: (a) the Agreement; (b) the Investor Rights Agreement, dated as of the date hereof, by and among Dresser, the Acquiror and Dresser Industries, Inc. (the "Investor Rights Agreement"); and (c) the Merger Agreement, dated as of the date hereof, between Dresser, Inc. and Merger Sub (the "Merger Agreement"). The documents described above are referred to herein collectively as the "Transaction Documents." HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX X

We are opining herein as to the effect on the subject transaction only of the federal laws of the United States, the internal laws of the State of New York, the Delaware General Corporation ("DGCL") and the Delaware Limited Liability Company Act ("DLLCA") and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws or as to any matters of municipal law or the laws of any other local agencies within any state. Our opinions set forth in paragraph 4 below are based upon our consideration of only those statutes, rules and regulations which, in our experience, are normally applicable to recapitalization transactions. Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof: 1. The Acquiror is a limited liability company, duly formed, validly existing and in good standing under the DLLCA with the requisite power and authority to enter into each of the Transaction Documents to which it is a party and perform its obligations thereunder. Merger Sub is a corporation, duly formed, validly existing and in good standing under the DGCL with corporate power and authority to enter into the Merger Agreement and perform its obligations thereunder. 2. The execution, delivery and performance of the Transaction Documents to which it is a party have been duly authorized by all necessary action of each of the Acquiror and Merger Sub, and each of the Transaction Documents to which it is a party have been duly executed and delivered by each of the Acquiror and Merger Sub. 3. The Agreement constitutes a legally valid and binding obligation of the Acquiror, enforceable against the Acquiror in accordance with its terms. 4. The execution and delivery of the Transaction Documents by the Acquiror and Merger Sub on the date hereof do not: (i) violate any federal or New York statute, rule or regulation applicable to the Acquiror or Merger Sub, (ii) violate the provisions of the Organizational Documents of the Acquiror or Merger Sub, (iii) result in the breach of or a default under any of the agreements to which the Acquiror or Merger Sub is a party set forth on Schedule A hereto, which are all of the agreements that have been identified to us by Acquiror as material to the Acquiror and Merger Sub taken as a whole (the "Material Agreements"), or (iv) require any consents, approvals, authorizations, registrations, declarations or filings by the Acquiror or Merger Sub under any federal or New York statute, rule or regulation applicable to the Acquiror or Sub. The opinions expressed in paragraph 3 above are subject to the following limitations, qualifications and exceptions: (a) the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors; HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX X-2

(b) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought; (c) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (d) the unenforceability of any provision requiring the payment of attorney's fees, except to the extent that a court determines such fees to be reasonable. No opinion is expressed in paragraph 4 as to the applicability of Section 547 and 548 of the United States Bankruptcy Code or applicable state law (including, without limitation, Article 10 of the New York Debtor and Creditor Law) relating to preferences and fraudulent transfers and obligations, or of any antifraud laws, securities laws, antitrust or trade regulation laws. In rendering the opinions expressed in paragraph 4 insofar as they require interpretation of the Material Agreements: (i) we have assumed with your permission that all courts of competent jurisdiction would enforce such agreements as written but would apply the internal laws of the State of New York without giving effect to any choice of law provisions contained therein or any choice of law principles which would result in application of the internal laws of any other state, (ii) to the extent that any questions of legality or legal construction have arisen in connection with our review, we have applied the laws of the State of New York in resolving such questions, (iii) we express no opinion with respect to the effect of any action or inaction by the Acquiror or Merger Sub under the Transaction Documents or the Material Agreements which may result in a breach or default under any Material Agreement, and (iv) we express no opinion with respect to any matters which require us to perform a mathematical calculation or make a financial or accounting determination. We advise you that certain of the Material Agreements may be governed by other laws, that such laws may vary substantially from the law assumed to govern for purposes of this opinion, and that this opinion may not be relied upon as to whether or not a breach or default would occur under the law actually governing such Material Agreements. To the extent that the obligations of the Acquiror or Merger Sub may be dependent upon such matters, we assume for purposes of this opinion that: all parties to the Transaction Documents other than the Acquiror and Merger Sub are duly organized, validly existing and in good standing under the laws of their respective jurisdictions of organization; all parties to the Transaction Documents other than the Acquiror and Merger Sub have the requisite power and authority to execute and deliver the Transaction Documents and to perform their respective obligations under the Transaction Documents to which they are a party; and the Transaction Documents to which such parties other than the Acquiror and Merger Sub are a party have been duly authorized, executed and delivered by such parties and constitute their legally valid and binding obligations, enforceable against them in accordance with their terms. HALLIBURTON COMPANY AGREEMENT AND PLAN OF RECAPITALIZATION APPENDIX X-3

We express no opinion as to compliance by any parties to the Transaction Documents with any state or federal laws or regulations applicable to the subject transactions because of the nature of their business. This opinion is rendered only to you and is solely for your benefit in connection with the transactions covered hereby. This opinion may not be relied upon by you for any other purpose, or furnished to, quoted to or relied upon by any other person, firm or corporation for any purpose, without our prior written consent.
