           AMENDED AND RESTATED AGREEMENT AND PLAN OF RECAPITALIZATION

         This AMENDED AND RESTATED AGREEMENT AND PLAN OF RECAPITALIZATION (this
"Agreement") dated as of April 10, 2001, is by and among Halliburton Company, a
Delaware corporation (the "Parent"), Dresser B.V., a Netherlands company and a
wholly owned indirect Subsidiary of the Parent (the "Seller") and DEG
Acquisitions, LLC, a Delaware limited liability company (the "Acquiror"). 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.

                                    RECITALS:

         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.

         After giving effect to the Reorganization, (a) the Parent desires to
cause Dresser Industries and DEGI to engage, and the Acquiror desires to engage,
and to cause Transitory Merger Sub to engage, in the transactions contemplated
by Article II herein at the First Closing and (b) immediately following the
First Closing, the Parent desires to cause the Seller to engage, and the
Acquiror desires to cause the Buyers to engage, in the transactions contemplated
by Article II herein at the Second Closing.

         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:


                               HALLIBURTON COMPANY

                  certificates or other documents at the Closings and where such
                  delivery is in the 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

                           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

                  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

                  substantially similar to the form thereof attached hereto as

                  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.

                           Regulation Section 1.1445-2; and

                  (iii)    such other documents and instruments as shall
                           evidence fulfillment or waiver of the Closing
                           Conditions.

         (e)      The Acquiror shall at the First Closing execute, where
                  appropriate, and deliver to the Parent such documents and
                  instruments as shall evidence fulfillment or waiver of the

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

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

                  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

                  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
                  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.

         (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 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).

         (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,

                  accumulated projected benefit obligation for the
                  post-retirement medical and life 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)      Solely for 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.


                               HALLIBURTON COMPANY

         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 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.

         (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

                  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.

                  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

                  consummation of the transactions contemplated hereby would
                  violate the terms of such Contractual Transfer Restriction,

Material Adverse Effect on the Businesses, no filing or registration with, no
waiting period imposed by, and no Authorization of, any Court or Governmental
Authority is required under any Legal Requirement applicable to the Parent or
any of its Affiliates (excluding the Seller and the members of the Company
Groups) to permit the Parent to execute, deliver or perform this Agreement or
any Ancillary Agreement to which it will be a party or to permit the Parent to
consummate the transactions contemplated hereby or thereby.

         Section 3.04. No Violation. Assuming effectuation of all filings and
registrations with, termination or expiration of any applicable waiting periods
imposed by, and receipt of all Authorizations of, any Court or Governmental
Authority indicated as required pursuant to Section 3.03, neither the execution
and delivery by the Parent of this Agreement or any Ancillary Agreement to which
it will be a party nor the performance by the Parent of its obligations
hereunder or thereunder will (a) violate or breach the terms of or cause a
default or give rise to rights under any Contractual Transfer Restrictions under
(i) any Legal Requirement applicable to the Parent or Dresser Industries, (ii)
the Organizational Documents of the Parent or Dresser Industries, or (iii) any

by a third Person, have any of the effects set forth in clause (a) of this
Section, except for any matters described in clauses (a)(i) and (a)(iii) of this
Section that could not reasonably be expected, individually or in the aggregate,

to which it will be a party in all material respects or to have a Material
Adverse Effect on the Businesses.

giving effect to the Reorganization will have, directly or indirectly, good
title to the Equity Securities of each member of the DEGI Group indicated as
owned, directly or indirectly, by DEGI on Schedule 5.03(a) to the Parent's
Disclosure Letter, free and clear of any Liens, and there are no contracts,
agreements, commitments or arrangements of the Parent or any of its Subsidiaries
obligating Dresser Industries (other than pursuant to this Agreement and the
Reorganization) to sell or to offer to sell any Equity Securities of any such
member of the DEGI Group or to purchase or acquire, or to offer to purchase or
acquire, any outstanding Equity Securities of any such member of the DEGI Group.
Upon consummation of the transactions contemplated hereby, the Acquiror will

hereunder directly or indirectly, free and clear of any such Liens (other than
any created by the Acquiror).

nature of its activities makes such qualification necessary in order for the
Seller to perform this Agreement and any Ancillary Agreement to which it is a
party in all material respects.

Seller in accordance with its terms, except as enforcement hereof or thereof may
be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,

                  Reorganization and the other transactions contemplated to be
                  consummated by it by this Agreement, and the consummation of
                  the Reorganization and such other transactions will have been,

                  provision thereof requiring any Third Person Consent) or (ii),

                  of any action by a third Person, have any of the effects set
                  forth in clause (i) of this subsection (c), except for any
                  matters described in clauses (A) and (C) of clause (i) of this
                  subsection (c) that could not reasonably be expected,
                  individually or in the aggregate, to prevent any member of
                  either Company Group from consummating the Reorganization or
                  the other transactions contemplated by this Agreement in all
                  material respects or to have a Material Adverse Effect on the

                  such Company Group member party thereto that is Material to
                  the Businesses and (B) any properties that are not,
                  individually or in the aggregate, Material to the Businesses.
                  Each such lease is valid and enforceable against the Company
                  Group member party thereto and, to the Knowledge of the
                  Parent, each other party thereto, in accordance with its terms

                  the Company Group member party thereto or, to the Knowledge of
                  the Parent, any other party thereto, or any condition, event
                  or act which, with notice or lapse of time or action of a
                  third Person, would constitute such a default, except in each
                  case for matters that could not reasonably be expected,

                  that could not reasonably be expected, individually or in the
                  aggregate, to have a Material Adverse Effect on the
                  Businesses.

                  entity has any rights including the name of the Company Group
                  member in whose name such Intellectual Property is registered
                  or which has such rights and the Business to which such
                  Intellectual Property relates. Except as could not reasonably
                  be expected to have a Material Adverse Effect on the
                  Businesses, as of the date hereof the members of the Company
                  Groups own, or have the valid right to use, all of the
                  Intellectual Property. Except as could not reasonably be
                  expected to have a Material Adverse Effect on the Businesses,
                  after giving effect to the Reorganization, the members of the
                  Company Groups which conduct each Business will own, or have
                  the valid right to use, all of the Intellectual Property used

                  the Initial Balance Sheet Date of the nature of liabilities
                  that may be incurred after the date of this Agreement pursuant
                  to subsection (b) of Section 8.02. None of the liabilities
                  described in clauses (iii) and (iv) of the preceding sentence
                  has or could reasonably be expected to have, individually or
                  in the aggregate, a Material Adverse Effect on the Businesses.

         (c)      The books, records and accounts of the members of the Company
                  Groups, in reasonable detail, accurately and fairly reflect in
                  the aggregate the transactions and dispositions of the assets
                  of the Businesses. No member of either Company Group has
                  engaged in any Material transaction, maintained any Material
                  bank account or used any Material corporate funds except for
                  transactions, bank accounts and funds that have been and are
                  reflected in the normally maintained Books and Records of such
                  member of either Company Group.

         (d)      The notes to the Initial Financial Statements fairly reflect
                  in all material respects all transactions between or among any
                  member of either Company Group and any Affiliate thereof
                  (other than transactions solely between or among the members
                  of the Company Groups).

         Section 5.06. Authorizations. Each member of each Company Group has
obtained all Authorizations that are necessary to carry on the Business related
thereto as currently conducted, except for any such Authorizations that its
failure to possess, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect on the Businesses. Each such
Authorization (i) is in full force and effect, (ii) has not been violated in any
respect and (iii) is not subject to any suspension, revocation or cancellation,
other than for matters, in any such case, that could not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect on the
Businesses. There is no action, proceeding or investigation pending or, to the
Knowledge of the Parent, threatened regarding suspension, revocation or
cancellation of any of such Authorizations, except in any circumstances in which
the suspension, revocation or cancellation of such

Authorizations could not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect on the Businesses.

         Section 5.07. Compliance With Laws; Regulation of Businesses. Each
member of each Company Group is and, to the extent that any noncompliance could
reasonably be expected to have current consequences, has been in compliance with
all applicable Laws and Regulations and any Orders applicable to any such
entity, other than Environmental Laws and, to the extent applicable to the
execution, delivery and performance of this Agreement, foreign competition Laws
and except such events of noncompliance or defaults that, individually or, with
respect to multiple events of noncompliance or defaults arising out of the same
facts or circumstances, in the aggregate, could not reasonably be expected to
have a Material Adverse Effect on the Businesses. To the Knowledge of the
Parent, each member of each Company Group has at all times been in compliance
with, and continues to comply with, the Foreign Corrupt Practices Act of 1977,
as amended.

         Section 5.08. Taxes. Except for any matter that could not reasonably be
expected, individually or in the aggregate, to have a Material Adverse Effect on
the Businesses:

         (a)      (i) all Tax Returns that were required to be filed by or with
                  respect to any member of a Company Group, or any member of the

                  Group, have been duly and timely filed, (ii) all items of
                  income, gain, loss, deduction and credit or other items ("Tax
                  Items") required to be included in each such Tax Return have
                  been so included and all such Tax Items and any other
                  information provided in each such Tax Return are true, correct
                  and complete insofar as such items are related to or affect a
                  member of a Company Group, (iii) all Taxes shown as due on
                  each such Tax Return have been timely paid in full insofar as
                  such Taxes are related to or affect a member of a Company
                  Group, (iv) insofar as such items are related to or affect a
                  member of a Company Group, no penalty, interest or other
                  charge is or will become due with respect to the late filing
                  of any such Tax Return or late payment of any such Tax and (v)
                  all Tax withholding and deposit requirements imposed on or
                  with respect to any member of a Company Group, or any member
                  of the Parent Group insofar as it affects any member of a
                  Company Group, have been satisfied in full in all respects;

         (b)      no member of a Company Group (or the Parent Group insofar as
                  it affects any member of a Company Group) has in force any
                  waiver of any statute of limitations in respect of Taxes or
                  any extension of time with respect to a Tax assessment or
                  deficiency;

         (c)      there are no pending Tax audits or examinations and no
                  proposed deficiencies or other claims for unpaid Taxes of any
                  member of a Company Group for which written notice has been
                  received;

         (d)      Schedule 5.08(d) to the Parent's Disclosure Letter contains a
                  list as of the date hereof of (i) all tax allocation or
                  sharing agreements to which any member of either Company Group
                  is a party and (ii) each member of a Company Group that has
                  any liability for the Taxes of any other Person (other than
                  members of its respective Company Group) under United States
                  Treasury Regulation section 1.1502-6 (or any similar provision
                  of state, local or foreign law);

         (e)      the aggregate unpaid Taxes of all members of the Company
                  Groups (computed with respect to each such member on the basis
                  of the income, operations and activities of such member
                  through the Closing Date as if the applicable taxable year of
                  such member ended on the Closing Date) did not, as of the date
                  of the Closing, exceed the amounts reserved for Tax liability
                  (as distinguished from any reserve for deferred taxes
                  established to reflect timing differences between book and tax
                  income) in the reserve for Taxes set forth on the face of
                  (rather than in any notes to) the Closing Financial
                  Statements;

         (f)      none of the assets of any member of any Company Group is
                  property required to be treated as being owned by any other
                  Person pursuant to the "safe harbor lease" provisions of
                  former Section 168(f)(8) of the Code;

         (g)      none of the assets of any member of any Company Group directly
                  or indirectly secures any debt the interest on which is
                  tax-exempt under Section 103(a) of the Code;

         (h)      none of the assets of any member of any Company Group is
                  "tax-exempt use property" within the meaning of Section 168(h)
                  of the Code;

         (i)      each member of each Company Group that is not a corporation is
                  properly classified for United States federal income tax
                  purposes as a partnership or a disregarded entity, and not as
                  an association or publicly traded partnership taxable as a
                  corporation. No member of a Company Group is a party to any
                  joint venture, partnership, limited liability company
                  agreement, or other arrangement or contract that could be
                  treated as a partnership for federal income tax purposes;

                  Dresser Industries and each member of the DEGI Group that is a
                  domestic corporation;

         (k)      the Parent is eligible to make an election under Section
                  338(h)(10) of the Code (and any comparable election under
                  state, local or foreign tax law) with respect to each member
                  of each Company Group that is a domestic corporation; and

         (l)      no claim has been made by a jurisdiction where any member of
                  any Company Group does not file Tax Returns or otherwise
                  comply with local taxation requirements (e.g.,


                               HALLIBURTON COMPANY

                  through a withholding tax regime) that such member is or may
                  be subject to taxation in that jurisdiction.

         Section 5.09. Principal Contracts.

         (a)      Schedule 5.09(a) to the Parent's Disclosure Letter contains a
                  list as of the date hereof of all Principal Contracts, other
                  than Related Party Contracts and Surety Arrangements,
                  including the name of the Company Group member that is a party
                  thereto and the Business to which each such Principal Contract
                  relates. Each such Principal Contract is in full force and
                  effect, and neither the member or members of either Company
                  Group party thereto nor, to the Knowledge of Parent, any other
                  party thereto, has failed to perform its obligations
                  thereunder to date, other than any failure of a Principal
                  Contract to be in full force and effect or of any
                  nonperformance thereof that could not, individually or in the
                  aggregate, reasonably be expected to have a Material Adverse
                  Effect on the Businesses. To the Knowledge of the Parent, no
                  party to any such Principal Contract has given or received any
                  notice of cancellation or termination of such Principal
                  Contract.

         (b)      Schedule 5.09(b) to the Parent's Disclosure Letter contains a
                  list as of the date hereof of all Principal Contracts that are
                  Related Party Contracts, including the name of each Company
                  Group member that is a party thereto and the Business to which
                  each such Related Party Contract relates, and identifies each
                  Retained Subsidiary of the Parent that is the party to each
                  such Related Party Contract. Each Related Party Contract is in
                  full force and effect and each party thereto has performed its
                  obligations thereunder to date.

         (c)      Schedule 5.09(c) to the Parent's Disclosure Letter contains a
                  list as of the date hereof of all Surety Arrangements,
                  including the name of each Company Group member that is a
                  beneficiary thereof and the Business to which the Surety
                  Arrangement relates, and identifies each surety in such
                  arrangement, whether that be the Parent or a Retained
                  Subsidiary. To the Knowledge of the Parent, all such Surety
                  Arrangements are in full force and effect, no Parent or
                  Retained Subsidiary is in default thereunder and no party to
                  any Surety Arrangement has given or received any notice of
                  cancellation or termination of any Surety Arrangement.

         Section 5.10. Employees.

         (a)      Except for matters that could not reasonably be expected to
                  have a Material Adverse Effect on the Businesses, (i) no
                  collective bargaining or similar agreement is being negotiated
                  by any member of either Company Group, (ii) there is no
                  pending or, to the Knowledge of the Parent, threatened labor
                  dispute, strike, slowdown, lockout or work stoppage against
                  any member of either Company Group, (iii) none of the members
                  of the Company Groups is a party to or bound by any collective
                  bargaining or similar agreement with any union or work rules
                  or practices agreed to with any

                  labor organization or employee association applicable to
                  employees of any member of either Company Group, (iv) none of
                  the employees of any member of either Company Group is
                  represented by any labor organization and, to the Knowledge of
                  the Parent, there are no current union organizing activities
                  among the employees of any member of either Company Group and
                  (v), to the Knowledge of the Parent, no member of either
                  Company Group is engaged in any unfair labor practice in
                  connection with the operation of the related Business, which
                  unfair labor practice is actionable under applicable Laws and
                  Regulations. Except for matters that could not reasonably be
                  expected to have a Material Adverse Effect on the Businesses,
                  since January 1, 1998, none of the members of either Company
                  Group has (A), without fully complying with the notice and
                  other requirements of the WARN Act, effectuated (i) a "plant
                  closing" (as defined in the WARN Act) affecting any site of
                  employment or one or more facilities or operating units within
                  any site of employment or facility of any such Company Group
                  member covered by the WARN Act or (ii) a "mass layoff" (as
                  defined in the WARN Act) affecting any site of employment or
                  facility of any such Company Group member covered by the WARN
                  Act; or (B) engaged in layoffs or employment terminations
                  sufficient to imply application of any foreign, state or local
                  Laws or Regulations relating to plant closing or mass layoffs
                  and requiring notice to employees in the event thereof without
                  complying with such Laws and Regulations.

         (b)      Schedule 5.10(b) to the Parent's Disclosure Letter sets forth
                  as of the date hereof a true and complete list of the
                  Significant Benefit Plans. Schedule 5.10(b) to the Parent's
                  Disclosure Letter also identifies which of the Significant
                  Benefit Plans constitute Parent Benefit Plans. The Parent has
                  made available to the Acquiror copies of all Significant
                  Benefit Plans and, for each such Significant Benefit Plan,

                  to be filed with an applicable Governmental Authority, (ii) a
                  copy of the most recent actuarial report and valuation of the

                  such report or valuation is required to be prepared by
                  applicable Laws and Regulations, (iii) a copy of the
                  organizational documents relating to any funding vehicle
                  established thereunder and a copy of the summary plan
                  description (if any) therefor, (iv) where applicable, the most
                  recent determination letter issued by the Internal Revenue
                  Service, (v) a complete description of any unwritten
                  Significant Benefit Plans, and (vi) summary plan descriptions,
                  summaries of material modifications, and any other material
                  communications distributed to participants. Except for the
                  Parent Benefit Plans, no Person that is not a member of a
                  Company Group is a participating employer or sponsor of any
                  Significant Benefit Plan. The Parent has made available to the
                  Acquiror copies of any retention agreements with any
                  management employees of any member of either Company Group
                  that were executed in contemplation of the transactions that
                  are the subject of this Agreement.

         (c)      Except for matters that, individually or in the aggregate,
                  could not reasonably be expected to have a Material Adverse
                  Effect on the Businesses:

                           Code, section 302 of ERISA or Title IV of ERISA, and
                           each Benefit Plan intended to be qualified under
                           section 401(a) of the Code (A) satisfies in form the
                           requirements of such section except to the extent
                           amendments are not required by law to be made until a
                           date after the Closing Date and (B) has received a
                           favorable determination letter from the Internal

                  (ii)     each Benefit Plan has been operated and administered
                           in compliance with its governing documents and all
                           applicable Legal Requirements;

                  (iii)    each member of each Company Group has performed all
                           obligations, whether arising by Legal Requirement or
                           by contract, required to be performed by it in
                           connection with the Benefit Plans;

                  (iv)     there are no actions, suits or claims pending (other
                           than routine claims for benefits) or, to the
                           Knowledge of the Parent, threatened against, or with
                           respect to, any of the Benefit Plans or their assets;

                  (v)      all contributions required to be made to the Benefit
                           Plans pursuant to their terms and the provisions of
                           all applicable Legal Requirements have been timely
                           made;

                  (vi)     other than routine applications, filings and
                           amendments and modifications, there is no matter
                           pending with respect to any of the Benefit Plans
                           before any Governmental Authority;

                  (vii)    each member of each Company Group is in substantial
                           compliance with all applicable Legal Requirements
                           mandating benefits for their employees;

                  (viii)   the execution and delivery of this Agreement and the
                           consummation of the transactions contemplated hereby
                           will not (except as otherwise provided in this
                           Agreement or pursuant to the terms of a Benefit Plan
                           as in effect on the date of this Agreement) (A)
                           require any member of either Company Group to make a
                           larger contribution to, or pay greater benefits or
                           accelerate vesting or other rights or provide other
                           rights under, any Benefit Plan than it otherwise
                           would, whether or not some other subsequent action or
                           event would be required to cause such payment or
                           provision to be triggered or (B) create or give rise
                           to any additional vested rights or service credits or

                           benefits or provision of other rights has been or
                           could be made under this Agreement, any Ancillary
                           Agreement, any Benefit Plan or otherwise that would
                           be reasonably likely to be nondeductible for United
                           States federal income tax purposes by any member of
                           either Company Group that is a United States person
                           (within the meaning of section 7701(a)(30) of the
                           Code) solely by virtue of section 162(m) or section
                           280G of the Code or that would be

                           reasonably likely to be an "excess parachute payment"
                           pursuant to Section 280G of the Code or that would be
                           an "excess parachute payment," but for the
                           application of Section 280G(b)(5) of the Code;

                  (x)      to the Knowledge of the Parent neither any member of
                           either Company Group nor any fiduciary of any Benefit
                           Plan has engaged in any transaction in violation of
                           Sections 404 or 406 of ERISA or any non-exempt
                           "prohibited transaction" as defined in Section
                           4975(c)(i) of the Code, or has otherwise violated the
                           provisions of Part 4 of Title I, Subtitle B of ERISA,
                           and, to the Knowledge of the Parent, no member of
                           either Company Group has knowingly participated in a
                           violation of Part 4 of Title I, Subtitle B of ERISA
                           by any fiduciary of a Benefit Plan (or other employee
                           benefit plan subject to ERISA) and, to the Knowledge
                           of the Parent, no member of either Company Group has
                           been assessed any civil penalty under Section 502(a)
                           of ERISA of a material amount which has not been paid
                           in full or accrued as a liability in the financial
                           statements;

                  (xi)     except pursuant to one or more of those Significant
                           Benefit Plans set forth on Schedule 5.10(b) to the
                           Parent's Disclosure Letter, none of the Parent,
                           either Company Group, or any Benefit Plan has any
                           present or future obligation to provide any benefits
                           to or make any payment with respect to any current or
                           former employee, director, officer, consultant or
                           agent of any Company Group pursuant to any
                           Significant Benefit Plan that is a retiree medical
                           benefit plan or other retiree welfare plan and no
                           condition exists that would prevent the Parent or
                           either Company Group from amending or terminating any
                           such plan;

                  (xii)    to the Knowledge of the Parent, each Benefit Plan
                           that is a "group health plan" has been operated in
                           all Material respects in compliance with the
                           provisions of Part 6 of Title I, Subtitle B;

                  (xiii)   to the Knowledge of the Parent, neither the Parent
                           nor any member of either Company Group nor any ERISA
                           Affiliate has announced, proposed, or agreed to any
                           changes to any Benefit Plan that would cause an
                           increase in benefits (or the creation of new
                           benefits) under any such Benefit Plan or that would
                           cause a material increase in the cost of maintaining
                           such Benefit Plan with respect to a Company Group;
                           and

                  (xiv)    to the Knowledge of the Parent, each Benefit Plan
                           that covers current or former employees, directors,
                           officers or consultants and that is not subject to
                           ERISA and the Code has been maintained in material
                           compliance with its

                           terms and with the requirements prescribed by any and
                           all applicable statutes, orders, rules and
                           regulations (including any special provisions
                           relating to the tax status of contributions to,
                           earnings of or distributions from such Benefit Plans
                           where each such Benefit Plan was intended to have tax
                           status) and has been maintained in good standing with
                           applicable statutes, orders, rules and regulations
                           (including any special provisions relating to the tax
                           status of contributions to, earnings of or
                           distributions from such Benefit Plans where each such
                           Benefit Plan was intended to have tax status) and has
                           been maintained in good standing with applicable
                           regulatory authorities.

         (d)      There does not now exist, nor do any circumstances exist that
                  could result in, any Controlled Group Liability of the Parent
                  or any of its ERISA Affiliates that could reasonably be
                  expected to become a liability of any member of either Company
                  Group following the First Closing. No liability under Title IV
                  of ERISA (including liabilities pursuant to Sections 4064,
                  4069 or 4204 of ERISA) has been incurred by any member of
                  either Company Group since the effective date of ERISA that
                  has not been satisfied in full and no such liability is
                  reasonably expected to arise with respect to any member of
                  either Company Group. To the extent that the representation in
                  the preceding sentence applies to any section of ERISA
                  pursuant to which either Controlled Group could have liability
                  with respect to an ERISA Affiliate, it is made not only with
                  respect to the Benefit Plans but also with respect to any
                  employee benefit plan subject to Title IV of ERISA to which
                  any member of either Company Group or any ERISA Affiliate
                  made, or was required to make, contributions during the
                  six-year period preceding the date of this Agreement. The
                  Pension Benefit Guaranty Corporation has not instituted
                  proceedings pursuant to section 4042 of ERISA to terminate any
                  of the Benefit Plans subject to Title IV of ERISA or, to the
                  Knowledge of the Parent, any plan maintained by any other
                  entity that would be considered a single employer with any
                  member of either Company Group pursuant to section 4001(b)(1)
                  of ERISA. As to any Benefit Plan subject to Title IV of ERISA,
                  there has been no "reportable event" (as defined in Section
                  4043(c) of ERISA and the regulations under such section and
                  for which the disclosure requirements of Regulation section
                  4043.1 et. seq., promulgated by the Pension Benefit Guaranty
                  Corporation, have not been waived) and no member of the
                  Company Groups nor Parent nor any ERISA Affiliate is subject
                  to Section 4043(b) of ERISA and no analogous event has
                  occurred under applicable foreign law. Within the past six
                  years, neither any Benefit Plan nor any other plan maintained
                  by any entity that would be considered a single employer with
                  any member of either Company Group pursuant to section
                  4001(b)(1) of ERISA is or was a "multiemployer plan" (as such
                  term is defined in section 3(37) of ERISA).

         Section 5.11. Environmental Matters. Notwithstanding anything to the
contrary in this Article V or in any other section of this Agreement, the
representations and warranties set forth in this Section 5.11 are the only
representations and warranties thereof of the Parent in any way relating to
environmental matters, including the Environmental Laws, Authorizations under
any Environmental Laws and Hazardous Materials, and the remaining
representations and warranties in

this Agreement shall be construed not to apply to such matters. Employee health
and safety matters are covered by Section 5.07. Except for matters that could
not reasonably be expected to have a Material Adverse Effect on the Businesses,
Schedule 5.11 to the Parent's Disclosure Letter sets forth:

         (a)      to the Knowledge of the Parent, all Hazardous Materials
                  Contamination on, about or under the Real Property as of the
                  date of this Agreement;

         (b)      to the Knowledge of the Parent, all Environmental Compliance
                  Matters related to the Businesses as of the date of this
                  Agreement;

         (c)      all existing, pending or, to the Knowledge of the Parent,
                  threatened actions, suits, investigations, CERCLA potentially
                  responsible party notices, inquiries and proceedings by or
                  before any Court or Governmental Authority under any
                  applicable Environmental Laws as of the date of this Agreement
                  against any member of either Company Group; and

         (d)      Schedule 5.11 to the Parent's Disclosure Letter includes a
                  listing of all the environmental site assessment reports
                  prepared in connection with the transactions contemplated
                  hereby, all of which have heretofore been delivered to the
                  Acquiror.

         Section 5.12. Litigation. There are no actions, suits, arbitrations,
proceedings or investigations pending or, to the Knowledge of the Parent,
threatened against the Parent, the Seller or any member of either Company Group,
including any involving a claim for indemnification pursuant to any statute,
Organizational Document or contract relating to any other action, suit,
arbitration, proceeding or investigation, in or before any Court or before or by
any Governmental Authority, except actions, suits, proceedings or investigations
as disclosed in the Parent's Disclosure Letter pursuant to Section 5.07, 5.10 or
5.11 or that, individually or, with respect to multiple actions, suits or
proceedings that allege similar theories of recovery based on the same or
substantially the same facts or occurrences, in the aggregate, could not
reasonably be expected, in the case of any member of either Company Group, to
have a Material Adverse Effect on the Businesses or, in the case of any of the
Parent or the Seller, to prevent, enjoin or delay materially the performance of
this Agreement, and the Parent has no Knowledge of any facts which could give
rise to any such action, suit, arbitration, proceeding or investigation. Neither
the Parent nor the Seller nor any member of either Company Group is subject to
any judgment, injunction, order, ruling or decree that could reasonably be
expected, individually or in the aggregate, in the case of any member of either
Company Group, to have a Material Adverse Effect on the Businesses or, in the
case of the Parent or the Seller, to prevent or enjoin or delay materially the
performance of this Agreement.

         Section 5.13. Material Adverse Changes.

         (a)      Since the Initial Balance Sheet Date, no event, condition or
                  circumstance has occurred resulting in any change in or effect
                  on any Business (except for (i) such changes or effects
                  resulting from changes in general economic, regulatory or
                  political conditions (including foreign exchange rate
                  movements or devaluations), (ii) such


                               HALLIBURTON COMPANY

                  changes or effects affecting generally the industry in which
                  such Business participates and (iii) any such changes or
                  effects disclosed in the Parent's Disclosure Letter pursuant
                  to any other representation or warranty contained in this
                  Article V) that has had or could reasonably be expected to
                  constitute or have a Material Adverse Effect on the
                  Businesses.

         (b)      During the period from the Initial Balance Sheet Date to the
                  date of this Agreement, no member of either Company Group has
                  engaged in any conduct that is proscribed during the period
                  from the date of this Agreement to the Closing Date by clauses
                  (i) through (xvi) of subsection (b) of Section 8.02.

         Section 5.14. Customers and Suppliers. Schedule 5.14 to the Parent's
Disclosure Letter sets forth a true and correct list of (a) the 20 largest
customers of each Business, in terms of sales during each of the fiscal years
ended December 31, 1999 and 2000, setting forth the total sales to each such
customer during such period and (b) the 10 largest suppliers of each Business,
in terms of purchases during each of the fiscal years ended December 31, 1999
and 2000, setting forth for each such supplier the total purchases from each
such supplier during such period. Since the Initial Balance Sheet Date, to the
Knowledge of the Parent, there has not been any change in the business
relationship of the relevant members of either Company Group with any customer
or supplier named in Schedule 5.14 to the Parent's Disclosure Letter that could
reasonably be expected to have a Material Adverse Effect on the Businesses.

         Section 5.15. Adequacy of Assets. The assets and properties of the
members of the Company Groups constitute all of the assets, rights and
properties that are necessary for the conduct of the Businesses as now
conducted.

         Section 5.16. Full Disclosure. The Acquiror shall be entitled to rely
upon, and shall not be deemed to have knowledge of facts other than those set
forth in, the representations and warranties of the Parent and the Seller made
in this Agreement (including the Schedules to the Parent's Disclosure Letter
related hereto) and in the certificates delivered by or on behalf of the Parent
and the Seller confirming the accuracy of such representations and warranties
and pursuant to any disclosures in writing made to the Acquiror pursuant to
Section 12.02(c).

         Section 5.17. Disclaimers. THE ACQUIROR ACKNOWLEDGES THAT EXCEPT AS

required by Law, Regulation or such Buyer's Organizational Documents, by the
holder or holders of such Buyer's Equity Securities. Each Ancillary Agreement to
which it is a party will at the Second Closing have been duly executed and
delivered by each Buyer and (assuming due authorization, execution and delivery
thereof by each other party thereto) at the Second Closing each Ancillary
Agreement to which it is a party will constitute the legal, valid and binding
obligation of such Buyer, enforceable against such Buyer in accordance with its
terms, except as enforcement thereof may be limited by bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar Laws
relating to or affecting the enforcement of creditors' rights generally and
legal principles of general applicability governing the availability of
equitable remedies (whether considered in a proceeding in equity, at law or

waiting period imposed by and no Authorization of, any Governmental Authority or
Court is required under any Legal Requirement applicable to such Buyer to permit
such Buyer to execute, deliver or perform each Ancillary Agreement to which it

         Section 7.04. No Violation. Assuming effectuation of all filings and
registrations with, termination or expiration of any applicable waiting periods
imposed by, and receipt of all Authorizations of, any Court or Governmental
Authority indicated as required pursuant to

obligations thereunder will (a) violate or breach the terms of or cause a
default under (i) any Legal Requirement applicable to such Buyer, (ii) the
Organizational Documents of such Buyer or (iii) any contract or agreement to
which such Buyer is a party or by which it or any of its properties or assets is

                  commercially reasonable efforts consistent with their

                  through (xvi) of subsection (b) of this Section. In this
                  regard, the Acquiror acknowledges that none of the
                  Non-Controlled Entities is under the direct or indirect
                  control of the Parent.

         Section 8.03. Access to Information.

         (a)      Subject to any limitations on disclosures to which the Parent
                  and the Acquiror agreed in the Confidentiality Agreement, the
                  Parent shall, prior to the Closing Date, cause each member of
                  each Company Group (or, in the case of any Company Group
                  member that is a Non-Controlled Entity, use commercially
                  reasonable efforts to cause such Non-Controlled Entity) (i) to
                  afford to the Acquiror and its Representatives access, at
                  reasonable times upon reasonable prior notice, to the
                  officers, employees, agents, properties, offices and other
                  facilities of the Company Group member and to its Books and
                  Records and (ii) to furnish promptly to the Acquiror and its
                  Representatives such information concerning the properties,
                  contracts, records and personnel (including financial,
                  operating and other data and information) related to the
                  Businesses as may be reasonably requested, from time to time,
                  by or on behalf of the Acquiror; provided, that Acquiror's
                  Representatives (i) comply with the provisions of the
                  Confidentiality Agreement, (ii) comply with all applicable
                  safety and other rules of conduct of such offices and
                  facilities and (iii) do not unreasonably interfere with the
                  operation of such offices or facilities or the personnel
                  involved. In this regard, the Acquiror acknowledges that none
                  of the Non-Controlled Entities is under the direct or indirect
                  control of the Parent.

         (b)      Subject to any limitations on disclosures to which the Parent
                  and the Acquiror agreed in the Confidentiality Agreement, the
                  Parent shall, at any time following the issuance of a press
                  release or similar disclosure announcing the execution of this
                  Agreement and prior to the Closing Date, cause each member of
                  each Company Group to afford to the Acquiror and its
                  Representatives access, at reasonable times and upon
                  reasonable prior notice, to the customers and suppliers of
                  such Company Group member.

         (c)      All information provided to the Acquiror and the Acquiror's
                  Representatives pursuant to the Parent's Disclosure Letter and
                  otherwise pursuant to subsection (a) of this Section shall be
                  deemed to be "Evaluation Material" as that term is defined in
                  the Confidentiality Agreement but subject to the exclusions
                  and exceptions described therein.

         Section 8.04. Insurance Benefits. If, with respect to any of the
Assumed Obligations or, to the extent that the Acquiror is not then entitled to
indemnification therefor pursuant to Article XII, any of the Excluded
Liabilities, the Parent has prior to the Closing Date carried one or more
policies of insurance for the benefit of a member of a Company Group that may
provide coverage for such Assumed Obligation, then after the Closing Date the
Parent shall assist the Acquiror and its relevant Subsidiary in making a claim
for the benefits of such insurance; provided, however, that the Parent

shall have no liability with respect to the success or failure of such claim.
Neither the Acquiror nor, following the Closing Date, any Subsidiary of the
Acquiror shall have any rights as provided in this Section 8.04 with regard to
any insurance policies of the Parent that are in effect self insurance, such as
retrospectively rated, deductible or captive reinsured policies.

         Section 8.05. Compliance with Competition Laws Applicable to Designated
Regulatory Assets.

         (a)      Subject to the Acquiror's compliance with subsection (a) of
                  Section 10.01 and the satisfaction of the conditions contained
                  in subsection (b) of this Section, at any time after the
                  Closing Date and prior to the second anniversary of the
                  Closing Date, the Acquiror may elect to require, by giving
                  notice to the Parent of such election, the Parent or, if the
                  Parent so desires, an Affiliate of the Parent to repurchase
                  any Designated Regulatory Assets for cash consideration equal
                  to the value allocated to such Designated Regulatory Assets in
                  the column entitled "Allocated Dollar Amount" in Schedule 2.13
                  to the Parent's Disclosure Letter within 90 days after the
                  receipt of such notice by the Parent, and the Parent or, at
                  the election of the Parent, an Affiliate of the Parent shall
                  purchase such Designated Regulatory Assets for such cash
                  consideration within such period. To the extent that an amount
                  set forth in Schedule 2.13 to the Parent's Disclosure Letter
                  becomes the purchase price for any such entity as a Designated
                  Regulatory Asset, such amount shall be reduced by the amount
                  of any payment by the Parent to the Acquiror under Article XII
                  directly related to such entity.

         (b)      It shall be a condition to the Acquiror's right to exercise
                  the option with respect to any Designated Regulatory Assets as
                  provided in subsection (a) of this Section that:

                  (i)      such assets became Designated Regulatory Assets no
                           more than 90 days prior to the exercise of such
                           option;

                  (ii)     such Designated Regulatory Assets shall be
                           transferred to the Parent or an Affiliate of the
                           Parent, as applicable, free and clear of all Liens
                           (other than Liens in existence immediately prior to
                           the Closing) and shall not be subject to an aggregate
                           amount of liabilities materially in excess of the
                           aggregate liabilities to which such Designated
                           Regulatory Assets were subject immediately prior to
                           the Closing;

                  (iii)    the Acquiror shall agree, for a period of five years
                           from the date of the transfer of such Designated
                           Regulatory Assets to the Parent or an Affiliate of
                           the Parent, to provide or cause to be provided to or
                           to purchase or cause to be purchased from, as the
                           case may be, the Parent or an Affiliate of the
                           Parent, as applicable, such quantity and quality of
                           products, components, spare parts and services as the
                           other operations of the Businesses have historically
                           provided to, or purchased from, as the case may be,

                           and

                           date of transfer of such Designated Regulatory
                           Assets, the Acquiror shall represent and warrant to
                           the Parent or an Affiliate of the Parent, as
                           applicable, that the matters set forth in clauses (i)
                           and (ii) of this subsection (b) are true and correct
                           and that since the Closing Date, the Acquiror or any
                           other Person owning, operating or managing such
                           Designated Regulatory Assets has, in all Material
                           respects:

                           (B)      used all commercially reasonable efforts to
                                    preserve substantially intact the business
                                    organization and goodwill, if any,

                                    any key employees of such Designated
                                    Regulatory Assets, to perform in all
                                    material respects the material contracts and
                                    agreements relating to such Designated
                                    Regulatory Assets and to maintain the
                                    relationships with customers, regulators and
                                    suppliers of such Designated Regulatory
                                    Assets;

                           (C)      used all commercially reasonable efforts
                                    consistent with past practice to maintain
                                    and to keep such Designated Regulatory

                                    the Closing Date, ordinary wear and tear
                                    excepted, and to maintain supplies and
                                    inventories of such Designated Regulatory

                                    practice;

                           (D)      used all commercially reasonable efforts to
                                    maintain in full force and effect insurance,
                                    performance bonds, bank guarantees and

                                    Authorizations or renewals thereof to the

         (c)      The Acquiror shall have 60 days from and after the repurchase
                  by a member of the Parent Group of Designated Regulatory
                  Assets under subsection (a) of this Section 8.05 to present
                  the Parent with a reasonably viable plan pursuant to which (i)
                  one or more members of a Company Group would again purchase
                  all or a portion of such Designated Regulatory Assets or (ii)
                  such member or members of a Company Group would enter into a
                  contractual relationship with one or more Subsidiaries of the
                  Parent that would provide to the Parent and the Acquiror
                  approximately the same economic benefits and obligations as
                  such a purchase of all or a portion of the Designated
                  Regulatory Assets which plan (x) is reasonably likely to be
                  acceptable to all Governmental Authorities having jurisdiction
                  over such Designated Regulatory Assets and (y) may be
                  accomplished in no more than 24 months from the date of
                  repurchase by the member of the Parent Group. The Parent and
                  the Acquiror agree to negotiate in good faith and pursue such
                  plan on commercially reasonable terms so long as it is
                  practicable to do so but in any event no longer than 90 days.

         Section 8.06. Covenant Not to Compete. 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 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

                               HALLIBURTON COMPANY
                     AGREEMENT AND PLAN OF RECAPITALIZATION

                                       44
<PAGE>   51
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 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. After the Closing Date, the Parent shall provide
the Acquiror with copies of all written submissions, proposals, offers and
inquiries relating to Acquisition Proposals except to the extent that the
provisions of such information would violate any contractual obligation of the
Parent or its Retained Subsidiaries.

         Section 8.08 Accountants' Opinion and Consents. The Parent shall use
all commercially reasonable efforts to cause Arthur Andersen LLP to provide the
Acquiror, at the Acquiror's expense, with all opinions and consents (including
audit reports) with respect to the consolidated financial statements of the
Businesses necessary for inclusion in any offering memoranda prepared in
connection with any offering of securities pursuant to Rule 144A promulgated
under the Securities Act, or for the completion of filings with the SEC under
the Securities Act and the Securities Exchange Act of 1934, as amended (the
"Securities Exchange Act"), until such time as such financial statements,
opinions and consents are no longer required to be included in such filings by
the Securities Act, the Securities Exchange Act or the rules and regulations
promulgated thereunder.

         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
                  each Company Group with respect to solvency matters, comfort
                  letters of accountants and legal opinions as may be reasonably
                  requested by the Acquiror, provided, however, that the
                  advisors and personnel of the Parent shall not be required to
                  participate in meetings, due diligence sessions, or road shows
                  after the six month anniversary of the Closing Date.

         (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

                  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

         Section 8.10. Financial Statements.

         (a)      From the date hereof to the Closing Date, the Parent shall
                  provide the Acquiror with (i) monthly management reports on
                  the Businesses, (ii) an unaudited consolidated balance sheet
                  of the Businesses and the related consolidated statements of

                  days after the end of such calendar month and (iii) any other
                  financial reports prepared routinely by management of the
                  Company Groups.

         (b)      The Parent shall use all commercially reasonable efforts to
                  provide to the Acquiror, on or before February 28, 2001,
                  consolidated statements of assets contemplated for sale and

         Section 8.11. Assignments. To the extent that any assets listed in the
Parent's Disclosure Letter or that are otherwise Material to the Businesses are
not held by a member of any Company Group, the Parent shall, prior to the
Closing, effect the assignment of such assets to a member of a Company Group
designated by the Acquiror. 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. To the extent that any Liens exist with
respect to any assets and properties of any member of the Company Groups
securing debt of any member of the Parent Group, the Parent agrees to use all
commercially reasonable efforts to cause such Liens, to the extent they attach

         Section 8.13. Environmental Schedules. The Parent agrees that the
Parent will prepare and deliver to the Acquiror at the First Closing a revised
Schedule 5.11 to the Parent's Disclosure Letter to set forth all matters
described in clause (a), (c) and (e) of the definition of Indemnifiable
Environmental Matters as of the Closing Date, which Schedule 5.11 shall (a)
constitute a representation and warranty, which shall survive until the fifth
anniversary of the Closing Date, as to such matters as of the Closing Date

(ii) govern the matters subject to indemnification pursuant to the provisions of

                            COVENANTS OF THE ACQUIROR

         Section 9.01. Confidentiality Agreement. The parties hereto hereby
incorporate by reference the provisions of paragraphs 1 to 3, inclusive, and 8
to 11, inclusive of the Confidentiality Agreement (including any addenda
thereto).

         Section 9.02. Corporate Name. Neither the Acquiror nor any Buyer shall
acquire, and no member of either Company Group shall acquire or retain, any
rights to the name "Halliburton" (or any variation thereof) or any trademarks,
trade names or symbols related thereto. The Acquiror shall, as soon as
reasonably practicable after the Closing Date (and in any event, within 60 days
thereafter), cause each member of each Company Group to amend its Organizational
Documents to the extent necessary to remove the "Halliburton" name (and any
variations thereof) from the name of such company and to remove all trademarks,
trade names, logos and symbols related to such name from the properties and
assets (including all signs) of the members of the Company Groups.

         Section 9.03. Surety Arrangements. The Acquiror acknowledges the list
of Surety Arrangements set forth on Schedule 5.09(c) to the Parent's Disclosure
Letter. The Acquiror agrees to use all commercially reasonable efforts prior to
the Closing Date to substitute the credit of the Acquiror or a Subsidiary of the
Acquiror for that of the Parent or the Retained Subsidiary of the Parent in each
such Surety Arrangement, such substitution to take effect at the First Closing.
The Acquiror agrees that it will, from and after the Closing Date, indemnify and
hold the Parent and each Retained Subsidiary harmless from and against any and
all losses, claims and damages arising from any Surety Arrangement extant at the
First Closing and, to the extent that the Acquiror is not able to effect such a
substitution prior to the Closing Date, the Acquiror also agrees (a) to continue
to use, and to cause each Buyer to use, its commercially reasonable efforts
thereafter to effect such a substitution with respect to each Surety Arrangement
and (b) to provide to the Parent at the First Closing a letter of credit issued
by a responsible commercial bank reasonably acceptable to the Parent against
which the Parent and the Retained Subsidiaries may draw to the extent of any
loss or damage they may incur or suffer as a result of being required to perform
any obligations under any Surety Arrangements from and after the Closing Date.

         Section 9.04. Dresser Valve Division Contracts. From and after the
Closing Date, the Acquiror shall cause its Subsidiaries engaged in the Dresser
Valve Division Business to use their commercially reasonable efforts to amend
the executory alliance contracts, master purchase agreements and purchase orders
of the Dresser Valve Division Business that do not contain any provision
expressly prohibiting awards of consequential damages as a partial remedy for
breach of such contract to include such a provision prior to the first renewal
or extension thereof.

                                MUTUAL COVENANTS

         Section 10.01. Cooperation. The covenants in this Section 10.01 shall
apply to the parties hereto from and after the date of this Agreement:

         (a)      Each of the Parent and the Acquiror shall use, and shall cause
                  each of its respective Affiliates to use, all commercially
                  reasonable efforts (i) to take, or to cause to be taken, all
                  actions, and to do, or to cause to be done, all things that,
                  in either case, are necessary, proper or advisable under
                  applicable Legal Requirements (other than foreign competition
                  Laws except those of the Category 1, 2A and 2B Jurisdictions)
                  or otherwise to consummate and make effective the transactions
                  contemplated by this Agreement, (ii) subject to the provisions
                  of clause (iii) of this subsection (a), to obtain from any
                  Governmental Authorities and Courts any Authorizations or
                  Orders required to be obtained by the Parent or the Acquiror
                  or any of their Affiliates in connection with the
                  authorization, execution, delivery and performance of this
                  Agreement and the Ancillary Agreements and the consummation of
                  the transactions contemplated hereby and (iii) to make all
                  necessary filings as expeditiously as reasonably practicable,
                  and thereafter to make promptly any other required
                  submissions, with respect to this Agreement, the Ancillary
                  Agreements and the transactions contemplated hereby and
                  thereby required under the HSR Act, any foreign competition
                  Laws of a Category 1 Jurisdiction, a Category 2A Jurisdiction
                  or a Category 2B Jurisdiction that are applicable to the
                  transactions contemplated by this Agreement and any other
                  applicable Legal Requirements (other than foreign competition
                  Laws). With respect to the Laws of the Covered Jurisdictions,
                  the Parent and the Acquiror shall furnish or cause to be
                  furnished all information required for any application or
                  other filing to be made pursuant to any such Laws or any
                  applicable Regulations in connection with the transactions
                  contemplated by this Agreement.

         (b)      Each of the Parent and the Acquiror shall timely give or cause
                  to be given any notices to third Persons, and use, and cause
                  its respective Affiliates to use, commercially reasonable
                  efforts to obtain any Third Person Consents (i) necessary,
                  proper or advisable for Parent or the Acquiror, as the case
                  may be, to consummate the transactions contemplated by this
                  Agreement or to satisfy any of the Closing Conditions, (ii) in
                  the case of the Parent and its Affiliates, otherwise required
                  under any Principal Contracts in connection with the
                  consummation of the transactions contemplated hereby or (iii)
                  in the case of the Parent and its Affiliates, required in
                  order to prevent a Material Adverse Effect on the Businesses
                  from occurring prior to or after the Closing Date; provided,
                  however, that, with respect to Third Person Consents set forth
                  on Schedule 5.02(c), the Parent shall use, and cause its
                  Affiliates to use, efforts that are deemed customary and usual
                  in the jurisdiction in which any such Third Person Consent is
                  required to obtain any such Third Person Consent;

                  provided, further, that the Parent shall not be required to
                  expend an amount of money that would be unreasonable in light
                  of local custom and practice in order to obtain any such Third
                  Person Consent. The Parent and Acquiror shall cooperate with
                  each other in connection with the giving of all such notices
                  and the preparation of all consent or waiver requests or
                  agreement amendments. The Parent and the Acquiror shall
                  cooperate with each other in providing copies of all such
                  documents to the other party and its advisors, and, if
                  requested, shall accept all reasonable additions, deletions or
                  changes suggested in connection therewith. The Parent and
                  Acquiror shall furnish or cause to be furnished all
                  information requested by the other party in connection with
                  this subsection (b).

         (c)      Each of the Parent and the Acquiror shall give, and shall
                  cause its Affiliates to give, prompt notice to the other of
                  (i) any notice or other communication from any Person alleging
                  that the consent of such Person is or may be required in
                  connection with the transactions contemplated hereby, (ii) any
                  notice or other communication from any Governmental Authority
                  in connection with the transactions contemplated hereby, (iii)
                  any actions, suits, claims, investigations or proceedings
                  commenced or threatened in writing against, relating to or
                  involving or otherwise affecting the Parent, the Acquiror or
                  any member of a Company Group that relate to the consummation
                  of the transactions contemplated hereby and (iv) the
                  occurrence or nonoccurrence of any event the occurrence or
                  nonoccurrence of which would be reasonably likely (A) to cause
                  any Closing Condition relating to the obligations of the other
                  party not to be satisfied, (B) to cause a breach of the
                  covenants of such party under this Agreement or (C) to delay
                  or impede the ability of either the Parent or the Acquiror to
                  consummate the transactions contemplated by this Agreement or
                  to fulfill their respective obligations set forth herein. No
                  delivery of any notice pursuant to clause (iv) of this
                  subsection (c) shall cure any breach of any representation or
                  warranty of the party giving such notice contained in this
                  Agreement or otherwise limit or affect the remedies available
                  hereunder to the party receiving such notice.

         (d)      Each of the Parent and the Acquiror agree to cooperate and to
                  use, and to cause their Affiliates to cooperate and to use,
                  all commercially reasonable efforts, vigorously to contest and
                  to resist any action, including legislative, administrative or
                  judicial action, and to have vacated, lifted, reversed or
                  overturned any Order (whether temporary, preliminary or
                  permanent) of any Court or Governmental Authority that is in
                  effect and that restricts, prevents or prohibits the
                  consummation of the transactions contemplated by this
                  Agreement, including the vigorous pursuit of all available
                  avenues of administrative and judicial appeal and all
                  available legislative action. Each of the Parent and the
                  Acquiror also agree to use all commercially reasonable efforts
                  to take, or to cause to be taken, any and all actions,
                  including the disposition (by the Acquiror) or retention (by
                  the Parent) of assets or the withdrawal from doing business in
                  particular jurisdictions, required by any Court or
                  Governmental Authority as a condition to the granting of any
                  Authorization or Order


                               HALLIBURTON COMPANY
                     AGREEMENT AND PLAN OF RECAPITALIZATION

                  necessary for the consummation of the transactions
                  contemplated hereby or as may be required to avoid, lift,
                  vacate or reverse any legislative, administrative or judicial
                  action to the extent that such action would otherwise cause
                  any condition to the First Closing not to be satisfied or
                  would restrict, prevent or prohibit the consummation of the
                  transactions contemplated hereby; provided, however, that in
                  no event shall the Parent be required to take, or cause to be
                  taken, any action that could reasonably be expected to have a
                  Material Adverse Effect on the Parent or on the Businesses or
                  shall the Acquiror be required to take, or cause to be taken,
                  any action that could reasonably be expected to have a
                  Material Adverse Effect on the Acquiror or on the Businesses.

         (e)      The Parent shall use its commercially reasonable efforts
                  consistent with its fiduciary obligations to cause any
                  Non-Controlled Entity in which it has a direct or indirect
                  ownership interest to take action consistent with its other
                  obligations under this Section 10.01 including (i), where
                  appropriate, voting, directly or indirectly, the Equity
                  Securities owned by it directly or indirectly in such
                  Non-Controlled Entity in a manner consistent with such
                  obligations and (ii) instructing each director or similar
                  official of such Non-Controlled Entity appointed, directly or
                  indirectly, by it to act in a manner consistent with such
                  obligations so long as any such action does not violate such
                  director's or official's fiduciary duties. In this regard, the
                  Acquiror acknowledges that none of the Non-Controlled Entities
                  in which the Parent has a direct or indirect ownership
                  interest is under the direct or indirect control of the
                  Parent.

         (f)      Nothing in this Section 10.01 shall be deemed to require
                  divestiture of any securities or other assets owned prior to
                  the Closing Date by the Acquiror, any direct or indirect
                  holder of Equity Securities in the Acquiror or any Affiliate
                  of the foregoing Persons.

         Section 10.02. Ancillary Agreements. The Parent and the Acquiror agree
to execute and deliver at the First Closing:

                  (i)      the Merger Agreement;

                  (ii)     the Assignment of Name;

                  (iii)    the Highway 6 Lease Agreement;

                  (iv)     the Employee Benefits Agreement;

                  (v)      the Transition Services Agreement; and

                  (vi)     the Stockholders' Agreement.

         Section 10.03. Public Announcements. Promptly following the execution
and delivery of this Agreement, the Parent and the Acquiror shall issue
concurrent press releases with respect to the subject matter of this Agreement.
Pending the Closing Date, the Acquiror and the Parent shall consult with, and
obtain the prior approval of, the other, which shall not be unreasonably
withheld, before issuing any other press release or otherwise making any public
statements with respect to the transactions contemplated hereby. Neither the
Parent nor the Acquiror shall permit any of its Affiliates to make any press
release or public statement with respect to the transactions contemplated
hereby. Notwithstanding the foregoing, this Section shall not preclude any party
from issuing such press releases, making such other public statements or making
such filings with or applications to Governmental Authorities, including a
filing of a Current Report on Form 8-K by the Parent with the SEC with respect
to the transactions contemplated hereby, as such party in good faith believes to
be required under applicable Legal Requirements.

         Section 10.04. Transfer Taxes. The Parent and the Acquiror shall
cooperate in the preparation, execution and filing of all returns,
questionnaires, applications or other documents regarding any real property
transfer, sales, use, and stamp taxes, any transfer, recording, registration and
other fees and any similar taxes that become payable as a direct result of the
transactions contemplated hereby ("Transfer Taxes"). The Transfer Taxes that
become payable as a result of the transfers included in the Reorganization and
as a result of the sale of the Securities shall be paid 50% by the Acquiror and
50% by the Parent.

         Section 10.05. Expenses. Except as otherwise expressly provided herein,
all costs and expenses incurred by the Parent in connection with this Agreement
and the transactions contemplated hereby shall be paid by the Parent, and all
costs and expenses incurred by the Acquiror in connection with this Agreement
and the transactions contemplated hereby shall be paid by the Acquiror.
Notwithstanding the foregoing, the Acquiror shall be responsible for and shall
pay or reimburse the Parent for (i) all expenses incurred in connection with
steps I-7, I-8, I-9, I-10, I-12, I-13, II-1, II-10, III-1, IV-1, IV-3, V-1,
V-2A, V-4, V-6, V-11, V-16, V-19, V-27 and V29 in the Reorganization described
in Annex B and any actions taken at the direction of the Acquiror or any
individual that the Acquiror has identified in written notice to the Parent and
(ii) any Taxes that would not have been incurred but for such actions and steps.
For the avoidance of doubt all costs incurred in the formation of DI France
S.A.S. are the responsibility of the Acquiror and all costs incurred in the
formation of DI Singapore Pte Ltd. are the responsibility of Parent.
Notwithstanding the foregoing, the Parent shall be responsible for, and shall
pay or reimburse the Acquiror for, the expenses incurred as a result of
recording assignments of Intellectual Property and Real Property pursuant to
Section 8.11, whether prior to or after the Closings.

         Section 10.06. Tax Matters.

         (a)      Within 240 days after the Closing Date, the Acquiror in its
                  sole discretion may cause to be made a timely and effective
                  election under section 338(g) of the Code (a "Section 338
                  Election") with respect to a qualified stock purchase (within
                  the meaning of Section 338 of the Code) of any member of a
                  Company Group that is a foreign corporation.

         (b)      The Acquiror shall indemnify and hold harmless the Parent and
                  each member of the affiliated group of which the Parent is the
                  common parent (within the meaning of section 1504 of the Code)
                  from and against any United States federal or state income or
                  franchise Tax Consequence arising solely by reason of any
                  Section 338 Election made. A "Tax Consequence" shall include
                  (by way of example and not limitation) a reduction in or
                  change in characterization of available foreign taxes under
                  sections 901 or 902 of the Code.

         (c)      The Parent and the Acquiror shall make a joint election under
                  section 338(h)(10) of the Code and any similar election under
                  the applicable income tax law of any state or political
                  subdivision of the United States (collectively, the "Section
                  338(h)(10) Elections") with respect to the Acquiror's purchase
                  of the Securities of DEGI and any deemed purchase of the
                  Securities of any Subsidiary of DEGI that is a domestic
                  corporation within the meaning of Section 7701 of the Code.
                  The Acquiror shall prepare and submit to the Parent a proposed
                  allocation of the aggregate deemed sales price (as defined in
                  Treasury Regulation Section 1.338-4T) for each member of the
                  DEGI Group among the assets of each such member as soon as
                  practicable but not later than 240 days after the Closing
                  Date. The Parent shall approve and agree to the proposed
                  allocation unless the Parent reasonably determines that the
                  proposed allocation is improper. Neither the Acquiror nor the
                  Parent shall take any action inconsistent with, or fail to
                  take any action necessary for, the validity of the Section
                  338(h)(10) Elections, and, if an allocation schedule is agreed
                  to by the Acquiror and the Parent, the Acquiror and the Parent
                  shall adopt and utilize the asset values as determined on the
                  allocation schedule for the purpose of all Tax Returns filed
                  by them unless otherwise required by applicable law. Not later
                  than 240 days after the Closing Date, the Acquiror shall
                  prepare and deliver to the Parent an Internal Revenue Service
                  Form 8023 and any similar form under applicable state income
                  tax law (the "Forms") with respect to the Section 338(h)(10)
                  Elections, together with any completed schedules required to
                  be attached thereto, which Forms shall have been duly executed
                  by an authorized person for the Acquiror. The Parent shall
                  cause the Forms to be duly executed by an authorized person
                  for the Parent and shall provide an executed copy of the Forms
                  to the Acquiror, whereupon each shall duly and timely file the
                  Forms as prescribed by Treasury Regulation 1.338(h)(10)-1T or
                  the corresponding provisions of the applicable income tax law
                  of any state or political subdivision of the United States.
                  Each such executed Form provided to the Parent shall be
                  accompanied by a certificate of the secretary of the Acquiror
                  that documents the authority of the signatory to make the
                  Section 338(h)(10) Election.

         (d)      The Parent shall cause to be included in the consolidated U.S.
                  federal income Tax Returns (and the U.S. state income Tax
                  Returns of any U.S. state that permits consolidated, combined

                  extent permitted by law or administrative practice, (A) the
                  taxable year of DEGI and each of its Subsidiaries (after
                  reflecting the Reorganization) that is a domestic corporation
                  that includes the Closing Date shall be treated as closing on
                  (and including) the Closing Date and (B) all transactions

                  have occurred shall be reported on the Acquiror's consolidated
                  United States federal income tax return to the extent
                  permitted by Treasury Regulation Section
                  1.1502-76(b)(1)(ii)(B) and shall be similarly reported on
                  other Tax Returns of the Acquiror or its Affiliates.

         (e)      With respect to all Tax Returns required to be filed after the
                  Closing Date by or with respect to any member of a Company
                  Group other than those Tax Returns described in subsection (d)
                  of this Section, the Acquiror shall cause each such Tax Return
                  to be prepared, shall cause to be included in each such Tax
                  Return all Tax Items required to be included therein, shall
                  cause each such Tax Return to be timely filed with the
                  appropriate taxing authorities, and shall be responsible for

                  provisions of this subsection (e) with respect to a taxable
                  year that includes any period on or before the Closing Date
                  shall be prepared in a manner consistent with practices
                  followed in prior years with respect to similar Tax Returns,
                  except for changes required by changes in law or fact.

         (f)      With respect to all Tax Returns filed by or with respect to

                  the Parent shall be responsible for the payment of all Taxes
                  and shall be entitled to all refunds or credits of any Taxes
                  attributable to the periods covered by such Tax Returns and
                  shall have the right, at its sole cost and expense, to control
                  the defense, prosecution, settlement or compromise of any
                  proceeding involving any such Tax Return or the period covered
                  thereby, and the Acquiror shall take such action in connection
                  with any such proceeding as the Parent shall request from time
                  to time, including the selection of counsel and experts and
                  the execution of powers of attorney; provided, however, that
                  if Acquiror or any member of a Company Group would bear any
                  liability for Taxes at issue in such proceeding for which
                  Acquiror would not be indemnified pursuant to Article XII, or
                  if Acquiror or any member of a Company Group would be bound by
                  the results of such proceeding for Tax periods (or portions
                  thereof) beginning after the Closing Date, then (i) the
                  Acquiror may also participate in such proceeding at its own
                  expense and (ii) neither party may settle any such proceeding
                  without the written consent of the other party (which consent
                  shall not be unreasonably withheld). The Parent shall give
                  written notice to the Acquiror of, and the Acquiror shall, and
                  shall cause each member of a Company Group to, give written
                  notice to

                  the Parent, of its receipt of any notice of any audit,
                  examination, claim or assessment for any Tax which could
                  result in any such proceeding, within 20 Business Days after
                  the receipt of such notice. Failure of the Acquiror or any BV
                  Company or Subsidiary to give the Parent written notice of any
                  such audit, examination, or assessment within such 20 Business
                  Day period shall cause the provisions of Article XII to be
                  inapplicable to any Losses realized with respect to such Tax
                  but only to the extent Parent was actually prejudiced by such
                  failure.

         (g)      The Acquiror and the Parent shall cooperate fully, as and to
                  the extent reasonably requested by the other party, in
                  connection with the filing of Tax Returns pursuant to this
                  Section 10.06 and any audit, litigation or other proceeding
                  with respect to Taxes. Such cooperation shall include the
                  retention and (upon the other party's request) the provision
                  of records and information which are reasonably relevant to
                  any such proceeding and making employees (including employees
                  of any member of a Company Group) available on a mutually
                  convenient basis to provide additional information and
                  explanation of any material provided hereunder. The Acquiror
                  and the Parent agree (i) to retain all Books and Records with
                  respect to Tax matters pertinent to the any member of a
                  Company Group relating to any taxable period beginning before
                  the Closing Date until the expiration of the statute of
                  limitations (and, to the extent notified by the Acquiror or
                  the Parent, any extensions thereof) of the respective taxable
                  periods, and to abide by all record retention agreements
                  entered into with any taxing authority, and (ii) to give the
                  other party reasonable written notice prior to transferring,
                  destroying or discarding any such Books and Records and, if
                  the other party so requests, the Acquiror or the Parent, as
                  the case may be, shall allow the other party to take
                  possession of such Books and Records. The Acquiror and the
                  Parent further agree, upon request, to use their best efforts
                  to obtain any certificate or other document from any
                  Governmental Authority or any other Person as may be necessary
                  to mitigate, reduce or eliminate any Tax that could be imposed
                  (including, but not limited to, with respect to the
                  transactions contemplated hereby). The Acquiror and the Parent
                  further agree, upon request, to provide the other party with
                  all information that either party may be required to report
                  pursuant to Section 6043 of the Code and the Treasury
                  Regulations promulgated thereunder.

         Section 10.07. Offers to Employees.

         (a)      The Parent has listed in Schedule 10.07(a) to the Parent's
                  Disclosure Letter the names and positions of certain of those
                  employees of the Parent or one of the Retained Subsidiaries
                  that have been seconded to members of the Company Groups. The
                  Acquiror agrees that, pending the Closing Date and for a
                  period of six (6) months thereafter, neither the Acquiror nor
                  any of its Subsidiaries, including the Buyers and (after the
                  Closing Date) their Subsidiaries, will make any offer of
                  employment or solicit any request for employment to or from
                  any of the employees so listed, except (i) for any such
                  employees included in an agreed list contained in a letter of
                  even date


                               HALLIBURTON COMPANY

                  herewith from the Parent to the Acquiror or (ii) with the
                  prior written consent of the Parent. For purposes of the
                  preceding sentence, the term "employment" shall include an
                  employee/employer relationship and/or a consulting
                  relationship.

         (b)      The Parent and the Acquiror shall, and shall cause their
                  respective Subsidiaries to, use reasonable efforts to cause
                  each individual listed on Schedule 10.07(b) to enter into an
                  employment agreement with a member of a Company Group on terms
                  reasonably satisfactory to the Acquiror. In this regard, the
                  Acquiror agrees to offer terms of employment to such
                  individuals that are as good or better than their existing
                  terms of employment taken in the aggregate for each employee.

         Section 10.08. Related Party Contracts. Schedule 5.09(b) to the
Parent's Disclosure Letter provides a complete and accurate list of the Related
Party Contracts. To the extent that the Parent controls the parties to such
Related Party Contracts, the Parent agrees to cause such parties to terminate
each such Related Party Contract specified in Schedule 5.09(b) to the Parent's
Disclosure Letter prior to the Closing, such Related Party Contracts to be
replaced by the Transition Services Agreement and the Highway 6 Deed and the
Highway 6 Lease. Any contract that is between any member of the Parent Group and
any member of the Company Group but does not constitute a Principal Contract
shall terminate at the Closing.

         Section 10.09 Litigation Support.

         (a)      If and for so long as the Acquiror, any Buyer or any member of
                  either Company Group is actively contesting or defending
                  against any charge, complaint, claim or demand (a "Claim") or
                  any action, suit, proceeding, investigation or hearing (an
                  "Action") based thereon in connection with (i) any transaction
                  contemplated under this Agreement or (ii) any fact, situation,
                  circumstance, status, condition, activity, practice, plan,
                  occurrence, event, incident, action, failure to act or
                  transaction on or prior to the Closing Date involving any
                  member of either Company Group, the Parent and the Seller
                  shall, if neither the Parent nor any of its Subsidiaries is a
                  party to or involved in such Claim or Action, reasonably
                  cooperate with the contesting or defending party and its
                  counsel in the contest or defense, make reasonably available
                  their personnel and provide such testimony and reasonable
                  access to their Books and Records as shall be necessary in
                  connection with the contest or defense, the out-of-pocket
                  expense of which shall be for the account of the contesting or
                  defending party. The covenant contained in this subsection (a)
                  shall not apply to any matter that is subject to the
                  indemnification obligations of the parties under Article XII,
                  other than a Proceeding as to which an Indemnifying Party has
                  assumed the legal defense in accordance with subsection (d) of
                  Section 12.04 or under Section 12.05.

         (b)      If and for so long as the Parent, the Seller or any of their
                  respective Affiliates is actively contesting or defending
                  against any Claim or Action based thereon in connection with
                  (i) any transaction contemplated under this Agreement or (ii)
                  any fact, situation, circumstance, status, condition,
                  activity, practice, plan, occurrence, event, incident, action,
                  failure to act or transaction involving any of the Businesses,

                  the Acquiror, each Buyer and each member of each Company Group
                  shall, if neither the Acquiror nor any of its Subsidiaries is
                  a party to or involved in such Claim or Action, reasonably
                  cooperate with the contesting or defending party and its
                  counsel in the contest or defense, make reasonably available
                  their personnel and provide such testimony and reasonable
                  access to their Books and Records as shall be necessary in
                  connection with the contest or defense, the out-of-pocket
                  expense of which shall be for the account of the contesting or
                  defending party. The covenant contained in this subsection (b)
                  shall not apply to any matter that is subject to the
                  indemnification obligations of the parties under Article XII,
                  other than a Proceeding as to which an Indemnifying Party has
                  assumed the legal defense in accordance with subsection (d) of
                  Section 12.04 or under Section 12.05.

         Section 10.10. Post-Closing Matters.

         (a)      From and after the Closing Date, each party hereto agrees to
                  execute such further instruments or documents as any other
                  party may from time to time reasonably request in order to
                  confirm or carry out the transactions contemplated by this
                  Agreement; provided, however, that no such instrument or
                  document shall increase a party's liability beyond that
                  contemplated hereby.

         (b)      From and after the Closing Date, the Acquiror and each Buyer
                  shall cause each member of each Company Group (other than any
                  Non-Controlled Entity), and shall use all commercially
                  reasonable efforts to cause each Non-Controlled Entity, to
                  maintain copies of all Books and Records in the possession of
                  such members of the Company Groups and the Non-Controlled
                  Entities at the Closing Date and shall prevent such members of
                  the Company Groups, and shall use all commercially reasonable
                  efforts to prevent each Non-Controlled Entity, from destroying
                  any of such Books and Records for a period of six years
                  following the Closing Date or, to the extent applicable, the
                  period specified in clause (i) of subsection 10.06(g). During
                  the period of retention of such Books and Records, the
                  Acquiror and the Buyers shall cause such members of each
                  Company Group, and shall use all commercially reasonable
                  efforts to cause each Non-Controlled Entity, (i) to grant to
                  the Parent or the appropriate Seller and its Representatives
                  reasonable cooperation, access and staff assistance at all
                  reasonable times and upon reasonable notice to all of such
                  Books and Records of such entities relating to the period
                  prior to the Closing Date (including workpapers and
                  correspondence with taxing authorities) that are not otherwise
                  protected by legal privilege, (ii) to afford the Parent or the
                  appropriate Seller and its Representatives the right, at the
                  Parent's expense, to take extracts therefrom and to make
                  copies thereof and (iii) to have access to the employees of
                  the members of the Company Groups, all to the extent
                  reasonably necessary or appropriate for general business
                  purposes, including the preparation of tax returns and the
                  handling of tax audits, disputes and litigation; provided,
                  however, that such requested cooperation, access and
                  assistance shall not unreasonably interfere with the normal
                  operations of the Businesses. In this regard, the Parent
                  acknowledges that the


                               HALLIBURTON COMPANY

                  Non-Controlled Entities will not be under the direct or
                  indirect control of the Acquiror.

         (c)      To the extent that the Acquiror shall, directly or indirectly,
                  sell or otherwise transfer its interests in any member of
                  either Company Group subsequent to the Closing Date, the
                  Acquiror agrees to use all reasonable efforts to obtain from
                  the transferee of such interests an obligation to comply with
                  the provisions of subsection (b) of this Section, which
                  obligation shall be enforceable by the Parent as a third party
                  beneficiary.

         Section 11.01. Conditions to Obligations of Each Party Under This
Agreement. The respective obligations of the Parent and the Acquiror to
consummate the transactions contemplated hereby shall be subject to the
satisfaction at or prior to the First Closing of the following conditions, any
or all of which may be waived by the parties hereto, in whole or in part, to the

                  (whether temporary, preliminary or permanent) that is in
                  effect and prohibits or renders illegal the transactions
                  contemplated hereby in a manner that is Material and adverse
                  to the Parent, the Acquiror or the Businesses.

                           thereto, but shall terminate and be of no further
                           force or effect on the third anniversary of the

                           asserted in writing (which states with specificity
                           the basis therefor) in accordance with Section 12.04
                           or Section 12.05 during such applicable survival
                           period shall, with respect only to such claim,

                           survival period pending resolution of the claim. The
                           covenants and agreements in this Article XII shall
                           survive the Closings and shall remain in full force

                           Closings without any contractual limitation on the
                           period of survival.

                           (D)      the Losses incurred by an Indemnified Party
                                    shall, for purposes of determining the
                                    maximum amount or threshold level thereof in
                                    accordance with this sentence and otherwise
                                    with respect to the obligations of the
                                    Indemnifying Parties hereunder, be offset by
                                    (i) the proceeds of any insurance received
                                    directly or indirectly by the Indemnified
                                    Party with respect thereto and (ii) the
                                    amount of any income tax benefit actually
                                    realized by the Indemnified Party with
                                    respect thereto.

                  For purposes of clause (i) of this subsection (a), the
                  representations and warranties of the Parent contained in this
                  Agreement shall, except for each instance in which a
                  representation and warranty regarding the completeness or
                  accuracy of a list or Schedule to the Parent's Disclosure
                  Letter is qualified as to materiality, be deemed to have been
                  made without any qualification as to materiality and,
                  accordingly, all references in such representations and
                  warranties to "Material", "Materially," "Material Adverse
                  Effect" and similar terms and phrases (including references to
                  dollar thresholds therein) shall be deemed to be deleted
                  therefrom.

         (b)      Notwithstanding anything to the contrary in this Agreement,
                  the liability of the Parent as an Indemnifying Party under
                  this Agreement shall also be limited as follows:

                  (i)      The amount payable by the Parent in respect of any
                           Losses incurred by an entity partially owned,
                           directly or indirectly, by an Indemnified Party shall
                           be determined by multiplying the total amount that
                           would otherwise be payable in respect of such Losses
                           by a percentage equal to the percentage of the Equity
                           Securities of such entity transferred to the
                           Acquiror, directly or indirectly, pursuant to this
                           Agreement.

                  (ii)     The Parent shall not be liable for any Losses
                           resulting from a breach of any of the representations
                           and warranties set forth in Articles III, IV or V of
                           this Agreement to the extent that:

<PAGE>   73


                           (A)      the liability for such breach occurs or is
                                    increased as a result of the adoption or
                                    imposition of any Law, Regulation or Order
                                    not in force at the date of this Agreement
                                    or as a result of any increase in rates of
                                    taxation after the date of this Agreement;
                                    or

                           (B)      the Losses would not have arisen but for a
                                    change in accounting policy or practice of
                                    the Acquiror or any member of the Company
                                    Groups after the Closing Date (other than
                                    changes required for any such accounting
                                    policy or practice to comply with U.S. GAAP
                                    as in effect on the Closing Date).

                  (iii)    The Parent shall be liable for any Loss resulting
                           from a breach of any of the representations and
                           warranties set forth in Section 5.08 only if and to
                           the extent that such Loss is not offset by a deferred
                           Tax asset that would properly be reflected in the
                           Closing Financial Statements. Notwithstanding the
                           foregoing, if the amount of such Loss exceeds $20.0
                           million, the amount of such Loss shall only be offset
                           by the present value of any such deferred Tax asset,
                           which present value shall be determined (A) using a
                           discount rate equal to DEGI's average cost of capital
                           at the date of the Loss and (B) on the assumption
                           that the corresponding Tax benefit is utilized as
                           soon as possible and at the maximum rate of Tax under
                           applicable Laws, without regard to any limitations
                           arising from any Tax attributes of the taxpayer.

                  (iv)     The Parent shall not be liable for any Loss incurred
                           by the Acquiror, the Buyers or any member of either
                           Company Group that arises out of or results from the
                           implementation of the steps of the Reorganization
                           referred to in the last sentence of Section 10.05 or
                           from any action taken at the direction of the
                           Acquiror or any individual that the Acquiror had
                           identified in written notice to the Parent.

         (c)      Notwithstanding anything herein to the contrary, to the extent
                  that the Acquiror waives satisfaction of one or more
                  conditions set forth in subsection (a) or (b) of Section
                  11.03, which conditions were not satisfied due to one or more
                  events, conditions or circumstances that occurred after the
                  date of this Agreement and that were specifically disclosed in
                  writing to the Acquiror prior to the Closing Date, the Parent
                  shall not have any liability hereunder for such matter or
                  matters to the extent so disclosed.

         (d)      The procedures set forth in Section 12.04 shall govern the
                  disposition of claims for indemnification brought pursuant to
                  this Section 12.02 except that any claim for indemnification
                  regarding an Indemnifiable Environmental Matter shall, in
                  addition, be subject the provisions of Section 12.05. In the
                  event of a conflict between the provisions of Section 12.04

         Section 12.03. General Indemnification by the Acquiror.

         (a)      If the transactions contemplated hereby to occur at the
                  Closings are effected and subject to the provisions of
                  subsection (b) of Section 12.01, the Acquiror hereby agrees
                  (in such capacity, an "Indemnifying Party"), from and after
                  the Closing Date, to indemnify and hold harmless the Parent
                  and the Seller, their Affiliates, directors, officers and
                  employees (in such capacity, an "Indemnified Party") against
                  any Losses that such Indemnified Party shall actually incur,
                  to the extent that such Losses (or Proceedings):

                  (i)      arise out of or result from the untruth or breach of
                           any representation or warranty made in Article VI for
                           the benefit of the Parent; or

                  (ii)     arise out of or result from the nonperformance in
                           accordance with its terms of any covenant or
                           agreement made herein for the benefit of the
                           Indemnified Party by the Indemnifying Party; or

                  (iii)    arise out of or result from any acts or omissions to
                           act after the Closing Date by any Buyer or any member
                           of either Company Group hereunder; or

                  (iv)     arise out of or result from the nonpayment or
                           nonperformance of any of the Assumed Obligations; or

                  (v)      arise out of or result from the implementation of the
                           steps of the Reorganization referred to in the last
                           sentence of Section 10.05 or from any actions taken
                           at the direction of the Acquiror or any individual
                           that the Acquiror has identified in written notice to
                           the Parent; or

                  (vi)     arise out of or result from any matter set forth in
                           clause (i) through (vii), inclusive, of subsection
                           (d) of Section 12.05 arising after the Closing Date.

                  Notwithstanding the foregoing, the Indemnifying Party shall be
                  liable to the Indemnified Party under this Section 12.03 only
                  in the event and to the extent that the amount of Losses
                  incurred by the Indemnified Party exceeds the Deductible
                  Amount; provided, however, that:

                           (A)      no Loss subject to indemnification pursuant
                                    to clause (iii) or (iv) of this Section
                                    shall be subject to or counted toward the
                                    Deductible Amount;

                           (B)      the amount of such Losses that are subject
                                    to indemnification hereunder shall not
                                    exceed $950,000,000 (nine hundred fifty
                                    million dollars); and

                           (C)      the Losses incurred by an Indemnified Party
                                    shall, for purposes of determining the
                                    maximum amount or threshold level thereof in
                                    accordance with this sentence and otherwise
                                    with respect to the obligations of the
                                    Indemnifying Parties hereunder, be offset by
                                    (i) the proceeds of any insurance received
                                    directly or indirectly by the Indemnified
                                    Party with respect thereto and (ii) the
                                    amount of any income tax benefit actually
                                    realized by the Indemnified Party with
                                    respect thereto.

                  For purposes of clause (i) of this subsection (a), the
                  representations and warranties of the Acquiror contained in
                  this Agreement shall, except for each instance in which a
                  representation and warranty regarding the completeness or
                  accuracy of a list or Schedule to the Acquiror's Disclosure
                  Letter is qualified as to materiality, be deemed to have been
                  made without any qualification as to materiality and,
                  accordingly, all references in such representations and
                  warranties to "Material", "Materially," "Material Adverse
                  Effect" and similar terms and phrases (including references to
                  dollar thresholds therein) shall be deemed to be deleted
                  therefrom.

         (b)      Notwithstanding anything to the contrary in this Agreement,
                  the Acquiror shall not be liable for any Losses resulting from
                  a breach of any of the representations and warranties set
                  forth in Article VI of this Agreement to the extent that the
                  liability for such breach occurs or is increased as a result
                  of the adoption or imposition of any Law, Regulation or Order
                  not in force at the date of this Agreement or as a result of
                  any increase in rates of taxation after the date of this
                  Agreement.

         (c)      Notwithstanding anything herein to the contrary, to the extent
                  that the Parent waives satisfaction of one or more conditions
                  set forth in subsection (a) or (b) of Section 11.02, which
                  conditions were not satisfied due to one or more events,
                  conditions or circumstances that occurred after the date of
                  this Agreement and that were specifically disclosed in writing
                  to the Parent prior to the Closing Date, the Acquiror shall
                  not have any liability hereunder for such matter or matters to
                  the extent so disclosed.

         (d)      The procedures set forth in Section 12.04 shall govern the
                  disposition of claims for indemnification brought pursuant to
                  this Section 12.03.

         Section 12.04. Procedures.

         (a)      Promptly after (i) discovery by an Indemnified Party hereunder
                  of a Loss or (ii) receipt by the Indemnified Party of notice
                  of the commencement of any Proceeding, in each case, against
                  which it believes it is indemnified under this Article, the
                  Indemnified Party shall, if a claim in respect thereto is to
                  be made against the Indemnifying Party under this Article,
                  notify the Indemnifying Party in writing of the discovery or
                  commencement thereof (the "Indemnification Notice"); provided,

                  however, that the omission so to notify the Indemnifying Party
                  shall not relieve it from any liability that it may have to
                  the Indemnified Party to the extent that the Indemnifying
                  Party is not prejudiced by such omission; and provided,
                  further, that with respect to any Loss or Proceeding in
                  existence on the Closing Date with respect to an Excluded
                  Liability or with respect to any Indemnifiable Environmental
                  Matter to which reference is made in clause (a), (c) or (e) of
                  the definitions of that term, the Acquiror shall be deemed to
                  have given notice thereof to the Parent pursuant to this
                  subsection (a) and the Parent shall be deemed to have
                  responded to such notice in accordance with clause (ii) of
                  subsection (b) of this Section, all effective as of the
                  Closing Date.

         (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
                  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 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


                               HALLIBURTON COMPANY

                  (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 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


                               HALLIBURTON 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 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


                               HALLIBURTON COMPANY

                  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 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 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


                               HALLIBURTON COMPANY
                     AGREEMENT AND PLAN OF RECAPITALIZATION

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 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. Waiver. Either the Parent or the Acquiror hereto may (a)
extend the time for the performance of any of the obligations or other acts of
the other parties hereto, (b) waive any inaccuracies in the representations and
warranties of the other parties contained herein or in any document delivered
pursuant hereto and (c) waive compliance by the other parties with any of the
agreements or conditions contained herein. Any such extension or waiver shall be
valid only if set forth in an instrument in writing signed by the party to be
bound thereby.
