                            BAKER HUGHES INCORPORATED
                              RETIREMENT POLICY FOR
                    CERTAIN MEMBERS OF THE BOARD OF DIRECTORS

         BAKER HUGHES INCORPORATED, a corporation organized under the laws of
the State of Delaware (the "Company"), adopts the following Retirement Policy
(the "Policy") pursuant to action of its Board of Directors (the "Board") taken
on December 2, 1987.

         1. Eligibility. The Policy shall cover any member of the Board (a
"Director"), other than a Director who is or has ever been an officer or
employee of the Company.

         2. Retirement Benefit. Any eligible Director shall be paid a benefit
under the Policy as determined below upon the Director's total and permanent
disability, resignation from the Board or removal from the Board on account of
any Rule of Governance other than any rule relating to attendance. No benefit
shall be paid to an eligible Director who ceases to serve on the Board by reason
of death.

         3. Amount of Benefit. An eligible Director who is entitled to receive a
benefit under paragraph 2 shall be paid a benefit equal to the amount of the
annual basic retainer paid to Directors who are not employees of the Company, at
the rate in effect on December 31 of the year preceding the year in which the
eligible Director ceases to be a member of the Board, multiplied by the number
of years of his or her service on the Board, to a maximum of ten years, with a
proration of benefits on a monthly basis for partial years of service. In
determining the number of years of service of a Director who has been
reappointed or reelected to the Board after having received benefits hereunder,
the Director shall not receive credit for years of service (or portions thereof)

                                       2
<PAGE>

with respect to which the Director has been paid benefits hereunder but such
years (or portions thereof) shall be taken into account in applying the ten year
cap on benefits hereunder.

         4. Payment of Benefits. At the election of an eligible Director, his or
her retirement benefit shall be payable either annually or quarterly at the
annual or quarterly rate in effect as of the December 31 preceding the
Director's retirement. Annual benefits shall be payable with respect to any year
or part of a year of retirement on January 2 of the following year and quarterly
benefits shall be paid fifteen days after the end of each calendar quarter,
beginning on the first such date following the Director's retirement. In the
event an eligible Director does not make an election hereunder, his or her
benefits shall be paid on an annual basis.

         5. Termination of Benefits. Notwithstanding any other provision hereof
to the contrary, all benefits payable hereunder shall terminate upon the death
of an eligible Director. Upon the reappointment or reelection of a retired
Director to the Board, the payment of benefits hereunder with respect service on
the Board prior to said reappointment or reelection shall terminate.

         6. No Funding. Benefits under this Policy shall not be funded and shall
be paid by the Company from its general assets. No person shall have any
preferred claim on, or any beneficial ownership in, any assets of the Company
prior to the time such assets are paid to an eligible Director and all rights
created under this Policy shall be the mere unsecured contractual rights of an
eligible Director against the Company.

         7. No Assignment. No Director may sell, assign, encumber or otherwise
transfer, assign or alienate his or her interest under this Policy and any
attempt to do so shall be void and ineffective. In addition, the interest of a
Director shall not be subject to attachment, execution,

                                       3

garnishment, claims arising from proceedings in bankruptcy or any other form of
legal or equitable levy or lien.

         8. Miscellaneous. Nothing contained herein shall be construed as an
employment contract or give any Director the right to continue to serve as a
Director. This Policy may be amended or terminated at any time in the sole and
absolute discretion of the Board, provided that no amendment or termination
shall reduce benefits which are then in pay status. This Policy shall be
governed by and construed under the laws of the State of Delaware.

     SECTION 4.2 Conversion of Company Stock.

          (a) At the Effective Time, each share of the common stock, par value
     $0.01 per share, of Merger Sub outstanding immediately prior to the
     Effective Time shall be converted into and become one fully paid and
     non-assessable share of Common Stock, par value $1.00 per share, of the
     Surviving Corporation.

          (b) At the Effective Time, each share of the Company Common Stock
     issued and outstanding immediately prior to the Effective Time (other than
     shares of Company Common Stock (i) held in the Company's treasury or (ii)
     owned by Parent, Merger Sub or any other wholly owned Subsidiary (as
     defined in Section 10.15) of Parent or the Company) shall, by virtue of the
     Merger and without any action on the part of the holder thereof, be
     converted into the right to receive a number of shares of Parent Common
     Stock equal to the Exchange Ratio.

          (c) As a result of the Merger and without any action on the part of
     the holder thereof, each share of the Company Common Stock shall cease to
     be outstanding and shall be canceled and retired and shall cease to exist,
     and each holder of a certificate (a "Certificate") representing any shares
     of the Company Common Stock shall thereafter cease to have any rights with
     respect to such shares of the Company Common Stock, except the right to
     receive, without interest, Parent Common Stock and cash for fractional

     upon the surrender of such Certificate.

          (d) Each share of the Company Common Stock issued and held in the

                                                                          Page 8

     Time, the Company Options shall, by virtue of the Merger and without any
     further action on the part of the Company or the holder of any Company
     Option, be assumed by Parent in such manner that Parent (i) is a
     corporation "assuming a stock option in a transaction to which section
     424(a) applied" within the meaning of section 424 of the Code or (ii) to
     the extent that section 424 of the Code does not apply to any Company
     Option, would be such a corporation were section 424 of the Code applicable
     to such option. Each Company Option assumed by Parent shall be exercisable
     upon the same terms and conditions as under the applicable Company Stock
     Option Plan and the applicable option agreement issued thereunder, except
     that (i) each Company Option shall be exercisable for that whole number of
     shares of Parent Common Stock (rounded to the nearest whole share) into
     which the number of shares of the Company Common Stock subject to such
     Company Option immediately prior to the Effective Time would be converted
     under Section 4.2(b), and (ii) the option price per share of Parent Common
     Stock shall be an amount equal to the option price per share of Company
     Common Stock subject to such Company Option in effect

     immediately prior to the Effective Time divided by the Exchange Ratio (the
     price per share, as so determined, being rounded upward to the nearest full
     cent).

          (ii) Parent shall take all corporate action necessary to reserve for
     issuance a number of shares of Parent Common Stock equal to the number of
     shares of Parent Common Stock issuable upon the exercise of the Company
     Options assumed by Parent pursuant to this Section 4.2(e). From and after
     the date of this Agreement, except as provided in Section 7.1(f), no
     additional options shall be granted by the Company or its Subsidiaries
     under the Company Stock Option Plans or otherwise. At the Effective Time or
     as soon as practicable, but in no event more than three business days,
     thereafter, Parent shall file with the Securities and Exchange Commission
     (the "SEC") a Registration Statement on Form S-8 covering all shares of
     Parent Common Stock to be issued upon exercise of the Company Options and
     shall cause such registration statement to remain effective for as long as
     there are outstanding any Company Options.

     SECTION 4.3 Exchange of Certificates Representing Company Common Stock.

          (a) As of the Effective Time, Parent shall deposit, or shall cause to
     be deposited, with an exchange agent selected by Parent, which shall be
     Parent's transfer agent for the Parent Common Stock or such other party
     reasonably satisfactory to the Company (the "Exchange Agent"), for the
     benefit of the holders of shares of Company Common Stock, for exchange in
     accordance with this Article 4, certificates representing the shares of
     Parent Common Stock and the cash in lieu of fractional shares (such cash
     and certificates for shares of Parent Common Stock, together with any
     dividends or distributions with respect thereto, being hereinafter referred
     to as the "Exchange Fund") to be issued pursuant to Section 4.2 and paid
     pursuant to this Section 4.3 in exchange for outstanding shares of Company
     Common Stock.

          (b) Promptly after the Effective Time, Parent shall cause the Exchange

<PAGE>

                                                                          Page 9

     Agent to mail to each holder of record of one or more Certificates (other
     than to holders of Company Common Stock that, pursuant to Section 4.2(d),
     are canceled without payment of any consideration therefor): (A) a letter
     of transmittal (the "Letter of Transmittal") which shall specify that
     delivery shall be effected, and risk of loss and title to the Certificates
     shall pass, only upon delivery of the Certificates to the Exchange Agent
     and shall be in such form and have such other provisions as Parent and the
     Company may reasonably specify and (B) instructions for use in effecting
     the surrender of the Certificates in exchange for certificates representing
     shares of Parent Common Stock and cash in lieu of fractional shares. Upon
     surrender of a Certificate for cancellation to the Exchange Agent together
     with such Letter of Transmittal, duly executed and completed in accordance
     with the instructions thereto, the holder of such Certificate shall be
     entitled to receive in exchange therefor (x) a certificate representing
     that number of whole shares of Parent Common Stock and (y) a check
     representing the amount of cash in lieu of fractional shares, if any, and
     unpaid dividends and distributions, if any, which such holder has the right
     to receive in respect of the Certificate surrendered pursuant to the
     provisions of this Article 4, after giving effect to any required
     withholding tax, and the Certificate so surrendered shall forthwith be
     canceled. No interest will be paid or accrued on the cash in lieu of
     fractional shares and unpaid dividends and distributions, if any, payable
     to holders of Certificates. In the event of a transfer of ownership of
     Company Common Stock which is not registered in the transfer records of the
     Company, a certificate representing the proper number of shares of Parent
     Common Stock, together with a check for the cash to be paid in lieu of
     fractional shares, shall be issued to such a transferee if the Certificate
     representing such Company Common Stock is presented to the Exchange Agent,
     accompanied by all documents required to evidence and effect such transfer
     and to evidence that any applicable stock transfer taxes have been paid.

          (c) Notwithstanding any other provisions of this Agreement, no
     dividends or other distributions declared or made after the Effective Time
     with respect to Parent Common Stock with a record date after the Effective
     Time shall be paid with respect to the shares to be issued upon conversion
     of any Certificate until such Certificate is surrendered for exchange as
     provided herein. Subject to the effect of applicable laws, following
     surrender of any such Certificate, there shall be paid to the holder of the
     certificates representing whole shares of Parent Common Stock issued in
     exchange therefor, without interest, (i) at the time of such surrender, the
     amount of dividends or other distributions with a record date after the
     Effective Time theretofore payable with respect to such whole shares of
     Parent Common Stock and not

                                        4

     paid, less the amount of any withholding taxes which may be required
     thereon, and (ii) at the appropriate payment date, the amount of dividends
     or other distributions with a record date after the Effective Time but
     prior to surrender and a payment date subsequent to surrender payable with
     respect to such whole shares of Parent Common Stock, less the amount of any
     withholding taxes which may be required thereon.

          (d) At or after the Effective Time, there shall be no transfers on the

     stock transfer books of the Company of the shares of Company Common Stock
     which were outstanding immediately prior to the Effective Time. If, after
     the Effective Time, Certificates are presented to the Surviving
     Corporation, the presented Certificates shall be canceled and exchanged for
     certificates for shares of Parent Common Stock and cash in lieu of
     fractional shares, if any, deliverable in respect thereof pursuant to this
     Agreement in accordance with the procedures set forth in this Article 4.
     Certificates surrendered for exchange by any person constituting an
     "affiliate" of the Company for purposes of Rule 145(c) under the Securities
     Act of 1933, as amended (the "Securities Act"), shall not be exchanged
     until Parent has received a written agreement from such person as provided
     in Section 7.11.

          (e) No fractional shares of Parent Common Stock shall be issued
     pursuant hereto. In lieu of the issuance of any fractional share of Parent
     Common Stock pursuant to Section 4.2(b), cash adjustments will be paid to
     holders in respect of any fractional share of Parent Common Stock that
     would otherwise be issuable, and the amount of such cash adjustment shall
     be equal to such fractional proportion of the Parent Share Price.

          (f) Any portion of the Exchange Fund (including the proceeds of any
     investments thereof and any shares of Parent Common Stock) that remains
     unclaimed by the former stockholders of the Company one year after the
     Effective Time shall be delivered to Parent. Any former stockholders of the
     Company who have not theretofore complied with this Article 4 shall
     thereafter look only to Parent for payment of their shares of Parent Common
     Stock, cash in lieu of fractional shares and unpaid dividends and
     distributions on the Parent Common Stock deliverable in respect of each
     Certificate such former stockholder holds as determined pursuant to this
     Agreement.

          (g) None of Parent, the Surviving Corporation, the Exchange Agent or
     any other person shall be liable to any former holder of shares of Company
     Common Stock for any amount properly delivered to a public official
     pursuant to applicable abandoned property, escheat or similar laws.

          (h) In the event any Certificate shall have been lost, stolen or
     destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and, if required
     by the Surviving Corporation, the posting by such person of a bond in such
     reasonable amount as the Surviving Corporation may direct as indemnity
     against any claim that may be made against it with respect to such
     Certificate, the Exchange Agent will issue in exchange for such lost,
     stolen or destroyed Certificate the shares of Parent Common Stock and cash
     in lieu of fractional shares, and unpaid dividends and distributions on
     shares of Parent Common Stock as provided in Section 4.3(c), deliverable in
     respect thereof pursuant to this Agreement.

     SECTION 4.4 Adjustment of Exchange Ratio. In the event that, subsequent to
the date of this Agreement but prior to the Effective Time, the Company changes
the number of shares of Company Common Stock, or Parent changes the number of
shares of Parent Common Stock, issued and outstanding as a result of a stock
split, reverse stock split, stock dividend, recapitalization or other similar
transaction, the Exchange Ratio and other items dependent thereon shall be
appropriately adjusted.

     SECTION 4.5 Rule 16b-3 Approval. Parent agrees that the Parent Board of
Directors or the Compensation Committee of the Parent Board of Directors shall
at or prior to the Effective Time adopt resolutions specifically approving, for
purposes of Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), the receipt, pursuant to Section 4.2, of Parent
Common Stock and Parent stock options by officers and directors of the Company
who will become officers or directors of the Parent subject to Rule 16b-3.

                                    ARTICLE 5

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the disclosure letter delivered to Parent
concurrently with the execution hereof (the "Company Disclosure Letter") or as
disclosed with reasonable specificity in the Company Reports (as defined in
Section 5.7), the Company represents and warrants to Parent that:

     SECTION 5.1 Existence; Good Standing; Corporate Authority. The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation. The Company is duly qualified to do
business as a foreign corporation and is in good standing under the laws of any
jurisdiction in which the character of the properties owned or leased by it
therein or in which the transaction of its business makes such qualification
necessary, except where the failure to be so qualified would not have,
individually or in the aggregate, a Company Material Adverse Effect (as defined
in Section 10.9). The Company has all requisite corporate power and authority to
own, operate and lease its properties and to carry on its business as now
conducted. The copies of the Company's certificate of incorporation and bylaws
previously made available to Parent are true and correct and contain all
amendments as of the date hereof.

     SECTION 5.2 Authorization, Validity and Effect of Agreements. The Company
has the requisite corporate power and authority to execute and deliver this
Agreement, the Stock Option Agreements and all other agreements and documents
contemplated hereby. The consummation by the Company of the transactions
contemplated hereby and by the Stock Options Agreements has been duly authorized
by all requisite corporate action, other than, with respect to the Merger, the
approval and adoption of this Agreement by the Company's stockholders. This
Agreement and the Stock Option Agreements constitute the valid and legally
binding obligations of the Company, enforceable in accordance with their
respective terms, subject to applicable bankruptcy, insolvency, moratorium or
other similar laws relating to creditors' rights and general principles of
equity.

     SECTION 5.3 Capitalization. The authorized capital stock of the Company
consists of 150,000,000 shares of Company Common Stock and 25,000,000 shares of
preferred stock, par value $1.00 per share, of the Company ("Company Preferred
Stock") and, as of April 30, 1998, there were 54,802,834 shares of Company
Common Stock issued and outstanding and 4,360,254 shares of Company Common Stock
reserved for issuance upon exercise of outstanding Company Options, and no
shares of Company Preferred Stock issued and

<PAGE>

                                                                         Page 12

outstanding. All such issued and outstanding shares of Company Common Stock are
duly authorized, validly issued, fully paid, nonassessable and free of
preemptive rights. One right to purchase Series A Junior Participating Preferred
Stock (each, a "Company Right") issued pursuant to the Rights Agreement, dated
as of August 17, 1994 (the "Company Rights Agreement"), as amended, between the
Company and Chemical Trust Company of California is associated with and attached
to each outstanding share of Company Common Stock. As of the date of this
Agreement, except as set forth in this Section 5.3 or in the Stock Option
Agreements and except for any shares of Company Common Stock issued pursuant to
Company Stock Option Plans described in the Company Reports filed prior to the
date of this Agreement, there are no outstanding shares of capital stock and
there are no options, warrants, calls, subscriptions, convertible securities, or
other rights, agreements or commitments which obligate the Company or any of its
Subsidiaries to issue, transfer or sell any shares of capital stock or other
voting securities of the Company or any of its Subsidiaries. The Company has no
outstanding bonds, debentures, notes or other obligations the holders of which
have the right to vote (or which are convertible into or exercisable for
securities having the right to vote) with the stockholders of the Company on any
matter.

     SECTION 5.4 Significant Subsidiaries. For purposes of this Agreement,
"Significant Subsidiary" shall mean significant subsidiary as defined in Rule
1-02 of Regulation S-X of the Exchange Act. Each of the Company's Significant
Subsidiaries is a corporation or partnership duly organized, validly existing
and in good standing (where applicable) under the laws of its jurisdiction of
incorporation or organization, has the corporate or partnership power and
authority to own, operate and lease its properties and to carry on its business
as it is now being conducted, and is duly qualified to do business and is in
good standing (where applicable) in each jurisdiction in which the ownership,
operation or lease of its property or the conduct of its business requires such
qualification, except for jurisdictions in which such failure to be so qualified
or to be in

                                        6

11

good standing would not have a Company Material Adverse Effect. All of the
outstanding shares of capital stock of, or other ownership interests in, each of
the Company's Significant Subsidiaries is duly authorized, validly issued, fully
paid and nonassessable, and is owned, directly or indirectly, by the Company
free and clear of all liens, pledges, security interests, claims or other
encumbrances ("Liens"). Schedule 5.4 to the Company Disclosure Letter sets forth
for each Significant Subsidiary of the Company, its name and jurisdiction of
incorporation or organization.

     SECTION 5.5 No Violation of Law. Neither the Company nor any of its
Subsidiaries is in violation of any order of any court, governmental authority
or arbitration board or tribunal, or any law, ordinance, governmental rule or
regulation to which the Company or any of its Subsidiaries or any of their
respective properties or assets is subject, except as would not have,
individually or in the aggregate, a Company Material Adverse Effect. The Company
and its Subsidiaries hold all permits, licenses, variances, exemptions, orders,
franchises and approvals of all governmental authorities necessary for the
lawful conduct of their respective businesses (the "Company Permits"), except
where the failure so to hold would not have a Company Material Adverse Effect.
The Company and its Subsidiaries are in compliance with the terms of the Company

<PAGE>

                                                                         Page 13

Permits, except where the failure so to comply would not have a Company Material
Adverse Effect. To the knowledge of the Company, no investigation by any
governmental authority with respect to the Company or any of its Subsidiaries is
pending or threatened, other than those the outcome of which would not have a
Company Material Adverse Effect.

     SECTION 5.6 No Conflict.

          (a) Neither the execution and delivery by the Company of this
     Agreement or the Stock Option Agreements nor the consummation by the
     Company of the transactions contemplated hereby or thereby in accordance
     with the terms hereof or thereof will: (i) conflict with or result in a
     breach of any provisions of the certificate of incorporation or bylaws of
     the Company; (ii) violate, or conflict with, or result in a breach of any
     provision of, or constitute a default (or an event which, with notice or
     lapse of time or both, would constitute a default) under, or result in the
     termination or in a right of termination or cancellation of, or give rise
     to a right of purchase under, or accelerate the performance required by, or
     result in the creation of any Lien upon any of the properties of the
     Company or its Subsidiaries under, or result in being declared void,
     voidable, or without further binding effect, or otherwise result in a
     detriment to the Company or any of its Subsidiaries under, any of the
     terms, conditions or provisions of, any note, bond, mortgage, indenture,
     deed of trust, license, franchise, permit, lease, contract, agreement,
     joint venture or other instrument or obligation to which the Company or any
     of its Subsidiaries is a party, or by which the Company or any of its
     Subsidiaries or any of their properties is bound or affected; or (iii)
     contravene or conflict with or constitute a violation of any provision of
     any law, rule, regulation, judgment, order or decree binding upon or
     applicable to the Company or any of its Subsidiaries, except, in the case
     of matters described in clause (ii) or (iii), as would not have,
     individually or in the aggregate, a Company Material Adverse Effect.

          (b) Neither the execution and delivery by the Company of this
     Agreement or the Stock Option Agreements nor the consummation by the
     Company of the transactions contemplated hereby or thereby in accordance
     with the terms hereof or thereof will require any consent, approval or
     authorization of, or filing or registration with, any governmental or
     regulatory authority, other than (i) the filings provided for in Article 1
     and (ii) filings required under the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended (the "HSR Act"), the Exchange Act, the
     Securities Act or applicable state securities and "Blue Sky" laws and
     applicable foreign competition or antitrust laws ((i) and (ii)
     collectively, the "Regulatory Filings"), and listing on the NYSE of the
     Company Common Stock to be issued upon exercise of the option granted to
     Parent pursuant to the applicable Stock Option Agreement, except for any
     consent, approval or authorization the failure of which to obtain and for
     any filing or registration the failure of which to make would not have a
     Company Material Adverse Effect.

     SECTION 5.7 SEC Documents. The Company has made available to Parent each
registration statement, report, proxy statement or information statement (other
than preliminary materials) filed by the Company with the SEC since January 1,
1997, each in the form (including exhibits and any amendments thereto) filed

<PAGE>

                                                                         Page 14

                                        7

with the SEC (collectively, the "Company Reports"). As of their respective
dates, the Company Reports (i) were prepared in all material respects in
accordance with the applicable requirements of the Securities Act, the Exchange
Act, and the rules and regulations thereunder and (ii) did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements made therein, in the light
of the circumstances under which they were made, not misleading except for such
statements, if any, as have been modified by subsequent filings with the SEC
prior to the date hereof. Each of the consolidated balance sheets included in or
incorporated by reference into the Company Reports (including the related notes
and schedules) fairly presents in all material respects the consolidated
financial position of the Company and its Subsidiaries as of its date and each
of the consolidated statements of income, cash flows and changes in
stockholders' equity of the Company included in or incorporated by reference
into the Company Reports (including any related notes and schedules) fairly
presents in all material respects the results of operations, cash flows or
changes in stockholders' equity, as the case may be, of the Company and its
Subsidiaries for the periods set forth therein (subject, in the case of
unaudited statements, to (x) such exceptions as may be permitted by Form 10-Q of
the SEC and (y) normal year-end audit adjustments), in each case in accordance
with generally accepted accounting principles consistently applied during the
periods involved, except as may be noted therein. Except as and to the extent
set forth on the consolidated balance sheet of the Company and its Subsidiaries
at December 31, 1997, including all notes thereto, as of such date, neither the
Company nor any of its Subsidiaries had any liabilities or obligations of any
nature (whether accrued, absolute, contingent or otherwise) that would be
required to be reflected on, or reserved against in, a balance sheet of the
Company or in the notes thereto prepared in accordance with generally accepted
accounting principles consistently applied, other than liabilities or
obligations which would not have, individually or in the aggregate, a Company
Material Adverse Effect.

     SECTION 5.8 Litigation. There are no actions, suits or proceedings pending
against the Company or any of its Subsidiaries or, to the Company's knowledge,
threatened against the Company or any of its Subsidiaries, at law or in equity,
or before or by any federal, state or foreign commission, board, bureau, agency
or instrumentality, that are likely to have, individually or in the aggregate, a
Company Material Adverse Effect. There are no outstanding judgments, decrees,
injunctions, awards or orders against the Company or any of its Subsidiaries
that are likely to have, individually or in the aggregate, a Company Material
Adverse Effect.

     SECTION 5.9 Absence of Certain Changes. Since December 31, 1997, there has
not been (i) any event or occurrence that has had or is likely to have a
Material Adverse Effect with respect to the Company, (ii) any material change by
the Company or any of its Subsidiaries, when taken as a whole, in any of its
accounting methods, principles or practices or any of its tax methods, practices
or elections, (iii) any declaration, setting aside or payment of any dividend or
distribution in respect of any capital stock of the Company or any redemption,
purchase or other acquisition of any of its securities, or (iv) any increase in
or establishment of any bonus, insurance, severance, deferred compensation,
pension, retirement, profit sharing, stock option, stock purchase or other

employee benefit plan, except in the ordinary course of business.

     SECTION 5.10 Taxes.

          (a) Each of the Company, its Subsidiaries and each affiliated,
     consolidated, combined, unitary or similar group of which any such
     corporation is or was a member has (i) duly filed (or there has been filed
     on its behalf) on a timely basis with appropriate governmental authorities
     all tax returns, statements, reports, declarations, estimates and forms
     ("Returns") required to be filed by or with respect to it, except to the
     extent that any failure to file would not have, individually or in the
     aggregate, a Company Material Adverse Effect, and (ii) duly paid or
     deposited in full on a timely basis or made adequate provisions in
     accordance with generally accepted accounting principles (or there has been
     paid or deposited or adequate provision has been made on its behalf) for
     the payment of all taxes required to be paid by it, except to the extent
     that any failure to pay or deposit or make adequate provision for the
     payment of such taxes would not have, individually or in the aggregate, a
     Company Material Adverse Effect. The Company's aggregate adjusted basis for
     federal income tax purposes in its shares of Unova, Inc. immediately before
     the distribution by the Company to its stockholders of such shares was
     equal to at least $500 million.

          (b) (i) Except as set forth in the Company Disclosure Letter, the
     federal income tax returns of the Company and each of its Subsidiaries have
     been examined by the Internal Revenue Service (the "IRS") (or the
     applicable statutes of limitation for the assessment of federal income
     taxes for such periods have expired) for all periods; (ii) except to the
     extent being contested in good faith, all material deficiencies asserted as
     a result of such examinations and any other examinations of the Company and
     its Subsidiaries by any taxing authority have been paid fully, settled or
     adequately provided for in the financial statements contained in the
     Company Reports; (iii) as of the date hereof, neither the Company nor any
     of its Subsidiaries has granted any requests, agreements, consents or
     waivers to extend the statutory period of limitations applicable to the
     assessment of any taxes with respect to any Returns of the Company or any
     of its Subsidiaries; (iv) neither the Company nor any of its Subsidiaries
     is a party to, is bound by or has any obligation under any tax sharing,
     allocation or indemnity agreement or any similar agreement or arrangement
     that would have a Company Material Effect; and (v) neither the Company nor
     any of its Subsidiaries is a party to an agreement that provides for the
     payment of any amount that would constitute a "parachute payment" within
     the meaning of section 280G of the Code.

     For purposes of this Agreement, "tax" or "taxes" means all federal, state,
county, local, foreign or other net income, gross income, gross receipts, sales,
use, ad valorem, transfer, accumulated earnings, personal holding company,
excess profits, franchise, profits, license, withholding, payroll, employment,

     SECTION 5.11 Employee Benefit Plans.

     all U.S. Company Benefit Plans. The term "Company Benefit Plans" means all
     material employee benefit plans and other material benefit arrangements,
     including all "employee benefit plans" as defined in the Employee
     Retirement Income Security Act of 1974, as amended ("ERISA"), covering
     employees of the Company and its Subsidiaries. True and complete copies of
     the U.S. Company Benefit Plans and, if applicable, the most recent Form
     5500 and annual reports for each such plan have been made available to
     Parent.

          (b) Except as would not have, individually or in the aggregate, a
     Company Material Adverse Effect: all applicable reporting and disclosure
     requirements have been met with respect to the Company Benefit Plans; there
     has been no "reportable event," as that term is defined in section 4043 of
     ERISA, with respect to the Company Benefit Plans subject to Title IV of
     ERISA; to the extent applicable, the Company Benefit Plans comply, in all
     material respects, with the requirements of ERISA and the Code, and any
     Company Benefit Plan intended to be qualified under section 401(a) of the
     Code has been determined by the IRS to be so qualified; the Company Benefit
     Plans have been maintained and operated, in all material respects, in
     accordance with their terms, and there are no breaches of fiduciary duty in
     connection with the Company Benefit Plans; to the Company's knowledge,
     there are no pending or threatened claims against or otherwise involving
     any Company Benefit Plan and no suit, action or other litigation (excluding
     claims for benefits incurred in the ordinary course of Company Benefit Plan
     activities) has been brought against or with respect to any such Company
     Benefit Plan; all material contributions required to be made as of the date
     hereof to the Company Benefit Plans have been made or provided for; the
     Company does not maintain or contribute to any material plan or arrangement
     which provides or has any liability to provide life insurance, medical or
     other employee welfare benefits to any employee or former employee upon his
     retirement or termination of employment and the Company has not
     represented, promised or contracted (whether in oral or written form) to
     any employee or former employee that such benefits would be provided; with
     respect to the Company Benefit Plans or any "employee pension benefit
     plans," as defined in section 3(2) of ERISA, that are subject to Title IV
     of ERISA and have been maintained or contributed to within six years prior
     to the Effective Time by the Company, its Subsidiaries or any trade or
     business (whether or not incorporated) which is under common control, or
     which is treated as a single employer, with the Company or any of its
     Subsidiaries under

                                        9

14

     sections 414(b), (c), (m), or (o) of the Code, (i) neither the Company nor
     any of its Subsidiaries has incurred any direct or indirect liability under
     title IV of ERISA in connection with any termination thereof or withdrawal
     therefrom; (ii) there does not exist any accumulated funding deficiency
     within the meaning of section 412 of the Code or section 302 of ERISA,
     whether or not waived; and (iii) the actuarial value of the assets equal or

<PAGE>

                                                                         Page 17

     exceed the actuarial present value of the benefit liabilities, within the
     meaning of section 4041 of ERISA, based upon reasonable actuarial
     assumptions and asset valuation principles; and no prohibited transaction
     has occurred with respect to any Company Benefit Plan that would result in
     the imposition of any excise tax or other liability under the Code or
     ERISA.

          (c) Neither the Company nor any of its Subsidiaries nor any trade or
     business (whether or not incorporated) which is under common control, or
     which is treated as a single employer, with the Company or any of its
     Subsidiaries under sections 414(b), (c), (m), or (o) of the Code,
     contributes to, or has an obligation to contribute to, and has not within
     six years prior to the Effective Time contributed to, or had an obligation
     to contribute to, a multiemployer plan within the meaning of section 3(37)
     of ERISA. The execution of, and performance of the transactions
     contemplated in, this Agreement will not (either alone or upon the
     occurrence of any additional or subsequent events) constitute an event
     under any benefit plan, policy, arrangement or agreement or any trust or
     loan that will or may result in any payment (whether of severance pay or
     otherwise), acceleration, forgiveness of indebtedness, vesting,
     distribution, increase in benefits or obligations to fund benefits with
     respect to any employee of the Company or any Subsidiary thereof.

     SECTION 5.12 Labor Matters. Except as would not have a Company Material
Adverse Effect, (i) neither the Company nor any of its Subsidiaries is a party
to, or bound by, any collective bargaining agreement, contract or other
agreement or understanding with a U.S. labor union or U.S. labor organization
and (ii) to the Company's knowledge, there are no organizational efforts with
respect to the formation of a collective bargaining unit presently being made or
threatened involving employees of the Company or any of its Subsidiaries.

     SECTION 5.13 Environmental Matters. Except as would not have, individually
or in the aggregate, a Company Material Adverse Effect:

          (a) there are not any past or present conditions or circumstances that
     interfere with the conduct of the business of the Company and each of its
     Subsidiaries in the manner now conducted or which interfere with compliance
     with any order of any court, governmental authority or arbitration board or
     tribunal, or any law, ordinance, governmental rule or regulation related to
     human health or the environment ("Environmental Law");

          (b) there are not any past or present conditions or circumstances at,
     or arising out of, any current or former businesses, assets or properties
     of the Company or any Subsidiary of the Company, including but not limited
     to on-site or off-site disposal or release of any chemical substance,
     product or waste, which could reasonably be expected to give rise to: (i)
     liabilities or obligations for any cleanup, remediation, disposal or
     corrective action under any Environmental Law or (ii) claims arising for
     personal injury, property damage, or damage to natural resources; and

          (c) neither the Company nor any of its Subsidiaries has (i) received
     any notice of noncompliance with, violation of, or liability or potential
     liability under any Environmental Law or (ii) entered into any consent
     decree or order or is subject to any order of any court or governmental
     authority or tribunal under any Environmental Law or relating to the

<PAGE>

                                                                         Page 18

     cleanup of any hazardous materials contamination.

     SECTION 5.14 Intellectual Property. Except as previously disclosed to
Parent in writing, the Company and its Subsidiaries own or possess adequate
licenses or other valid rights to use all patents, patent rights, trademarks,
trademark rights and proprietary information used or held for use in connection
with their respective businesses as currently being conducted, except where the
failure to own or possess such licenses and other rights would not have,
individually or in the aggregate, a Company Material Adverse Effect, and there
are no assertions or claims challenging the validity of any of the foregoing
which are likely to have,

                                       10

15

individually or in the aggregate, a Company Material Adverse Effect. The conduct
of the Company's and its Subsidiaries' respective businesses as currently
conducted does not conflict with any patents, patent rights, licenses,
trademarks, trademark rights, trade names, trade name rights or copyrights of
others in any way likely to have, individually or in the aggregate, a Company
Material Adverse Effect. There is no material infringement of any proprietary
right owned by or licensed by or to the Company or any of its Subsidiaries which
is likely to have, individually or in the aggregate, a Company Material Adverse
Effect. The computer software operated, sold or licensed by the Company that is
material to its business or its internal operations is capable of providing or
is being or will be adapted, or is capable of being replaced, to provide
uninterrupted millennium functionality to record, store, process and present
calendar dates falling on or after January 1, 2000 in substantially the same
manner and with substantially the same functionality as such software records,
stores, processes and presents such calendar dates falling on or before December
31, 1999, except as would not have a Company Material Adverse Effect. The costs
of the adaptations and replacements referred to in the prior sentence will not
have a Company Material Adverse Effect.

     SECTION 5.15 Insurance. The Company and its Subsidiaries maintain insurance
coverage reasonably adequate for the operation of their respective businesses
(taking into account the cost and availability of such insurance).

     SECTION 5.16 No Brokers. The Company has not entered into any contract,
arrangement or understanding with any person or firm which may result in the
obligation of the Company or Parent to pay any finder's fees, brokerage or
agent's commissions or other like payments in connection with the negotiations
leading to this Agreement or the consummation of the transactions contemplated
hereby, except that the Company has retained as its financial advisor, the
arrangements with which have been disclosed in writing to Parent prior to the
date hereof.

     SECTION 5.17 Opinion of Financial Advisor. The Board of Directors of the
Company has received the opinion of to the effect that, as of the date of this
Agreement, the Exchange Ratio is fair, from a financial point of view, to the
holders of the Company Common Stock; it being understood and acknowledged by
Parent that such opinion has been rendered for the benefit of the Board of
Directors of the Company, and is not intended to, and may not, be relied upon by
Parent, its affiliates or their respective Subsidiaries.

     SECTION 5.18 Parent Stock Ownership. Neither the Company nor any of its
Subsidiaries owns any shares of capital stock of Parent or any other securities
convertible into or otherwise exercisable to acquire capital stock of Parent.

     SECTION 5.19 Reorganization. Neither the Company nor any of its
Subsidiaries has taken or failed to take any action, as a result of which the
Merger would not qualify as a reorganization within the meaning of section
368(a) of the Code.

     SECTION 5.20 Pooling. Neither the Company nor any of its Subsidiaries has
taken or failed to take any action, as a result of which the Merger would not
qualify as a "pooling of interests" for financial accounting purposes.

     SECTION 5.21 Vote Required. The affirmative vote of the holders of at least
a majority of the outstanding shares of Company Common Stock is the only vote of
the holders of any class or series of Company capital stock necessary to approve
this Agreement and the transactions contemplated hereby.

     SECTION 5.22 Amendment to the Company Rights Agreement. The Company has
amended or taken other action under the Company Rights Agreement so that none of
the execution and delivery of this Agreement or the Stock Option Agreements, the
conversion of shares of Company Common Stock into the right to receive Parent
Common Stock in accordance with Article 4 of this Agreement, the issuance of
shares of Company Common Stock upon exercise of the option granted to Parent
pursuant to the applicable Stock Option Agreement, and the consummation of the
Merger or any other transaction contemplated hereby or by the Stock Option
Agreement, will cause (i) the Company Rights to become exercisable under the
Company Rights Agreement, (ii) Parent or any of its Subsidiaries to be deemed an
"Acquiring Person" (as defined in the Company Rights Agreement), (iii) any such
event to be an event described in Section 11(a)(ii) or 13 of the Company Rights
Agreement or (iv) the "Shares Acquisition Date" or the "Distribution Date" (each
as

                                       11

defined in the Company Rights Agreement) to occur upon any such event, and so
that the Company Rights will expire immediately prior to the Effective Time. The
Company has delivered to Parent a true and complete copy of the Company Rights
Agreement, as amended to date.

     SECTION 5.23 Certain Approvals. The Company Board of Directors has taken
any and all necessary and appropriate action to render inapplicable to the
Merger and the transactions contemplated by this Agreement and the Stock Option
Agreements the provisions of Section 203 of the DGCL. No other state takeover or
business combination statute applies or purports to apply to the Merger or the
transactions contemplated by this Agreement or the Stock Option Agreements.

     SECTION 5.24 Certain Contracts. Neither the Company nor any of its
Subsidiaries is a party to or bound by any non-competition agreement or any
other agreement or obligation which purports to limit in any material respect
the manner in which, or the localities in which, all or any material portion of
the current business of the Company and its Subsidiaries, taken as a whole, or
the Parent and its Subsidiaries, taken as a whole, is conducted.

                    REPRESENTATIONS AND WARRANTIES OF PARENT
                                 AND MERGER SUB

     Except as set forth in the disclosure letter delivered to the Company
concurrently with the execution hereof (the "Parent Disclosure Letter") or as
disclosed with reasonable specificity in the Parent Reports (as defined in
Section 6.7), Parent and Merger Sub, jointly and severally, represent and
warrant to the Company that:

     SECTION 6.1 Existence; Good Standing; Corporate Authority. Parent and
Merger Sub are corporations duly incorporated, validly existing and in good
standing under the laws of their respective jurisdictions of incorporation.
Parent is duly qualified to do business as a foreign corporation and is in good
standing under the laws of any jurisdiction in which the character of the
properties owned or leased by it therein or in which the transaction of its
business makes such qualification necessary, except where the failure to be so
qualified would not have, individually or in the aggregate, a Parent Material
Adverse Effect (as defined in Section 10.9). Parent has all requisite corporate
power and authority to own, operate and lease its properties and to carry on its
business as now conducted. The copies of Parent's certificate of incorporation
and bylaws previously made available to the Company are true and correct and
contain all amendments as of the date hereof.

     SECTION 6.2 Authorization, Validity and Effect of Agreements. Each of
Parent and Merger Sub has the requisite corporate power and authority to execute
and deliver this Agreement, the Stock Option Agreements and all other agreements
and documents contemplated hereby to which it is a party. Each of the
consummation by Parent and Merger Sub of the transactions contemplated hereby,
including the issuance and delivery by Parent of shares of Parent Common Stock
pursuant to the Merger, and the consummation by Parent of the transactions
contemplated by the Stock Option Agreements, has been duly authorized by all
requisite corporate action, other than approval of the issuance of the shares of
Parent Common Stock pursuant to the Merger contemplated hereby by Parent's
stockholders as required by the rules of the NYSE. This Agreement and the Stock
Option Agreements constitute the valid and legally binding obligations of each
of Parent and Merger Sub to the extent it is a party, enforceable in accordance
with their respective terms, subject to applicable bankruptcy, insolvency,
moratorium or other similar laws relating to creditors' rights and general
principles of equity.

     SECTION 6.3 Capitalization. The authorized capital stock of Parent consists
of 400,000,000 shares of Parent Common Stock and 15,000,000 shares of preferred
stock, par value $1.00 per share, of Parent ("Parent Preferred Stock"), and, as
of May 1, 1998, there were 169,709,279 shares of Parent Common Stock issued and
outstanding and 6,286,974 shares of Parent Common Stock reserved for issuance
upon exercise of outstanding Parent options and no shares of Parent Preferred
Stock issued and outstanding. All such issued and outstanding shares of Parent
Common Stock are duly authorized, validly issued, fully paid, nonassessable and
free of preemptive rights. The shares of Parent Common Stock to be issued in
connection with the

                                       12

Merger, when issued in accordance with this Agreement, will be validly issued,
fully paid and nonassessable. As of the date of this Agreement, except as set
forth in this Section 6.3 or in the Stock Option Agreements and except for any
shares of Parent Common Stock issued pursuant to plans described in the Parent
Reports filed prior to the date of this Agreement, there are no outstanding
shares of capital stock and there are no options, warrants, calls,
subscriptions, convertible securities or other rights, agreements or commitments
which obligate Parent or any of its Subsidiaries to issue, transfer or sell any
shares of capital stock or other voting securities of Parent or any of its
Subsidiaries. Parent has no outstanding bonds, debentures, notes or other
obligations the holders of which have the right to vote (or which are
convertible into or exercisable for securities having the right to vote) with
the stockholders of Parent on any matter.

     SECTION 6.4 Significant Subsidiaries.

     (a) Each of Parent's Significant Subsidiaries is a corporation or
partnership duly organized, validly existing and in good standing (where
applicable) under the laws of its jurisdiction of incorporation or organization,
has the corporate or partnership power and authority to own, operate and lease
its properties and to carry on its business as it is now being conducted, and is
duly qualified to do business and is in good standing (where applicable) in each
jurisdiction in which the ownership, operation or lease of its property or the
conduct of its business requires such qualification, except for jurisdictions in
which such failure to be so qualified or to be in good standing would not have a
Parent Material Adverse Effect. All of the outstanding shares of capital stock
of, or other ownership interests in, each of the Parent's Significant
Subsidiaries is duly authorized, validly issued, fully paid and nonassessable,
and is owned, directly or indirectly, by the Parent free and clear of all Liens.
Schedule 6.4 to the Parent Disclosure Letter sets forth for each Significant
Subsidiary of Parent its name and jurisdiction of incorporation or organization.

     (b) All of the outstanding shares of capital stock of Merger Sub are owned
directly by Parent. Merger Sub was formed solely for the purpose of engaging in
the transactions contemplated hereby and has not engaged in any activities other
than in connection with the transactions contemplated by this Agreement.

     SECTION 6.5 No Violation of Law. Neither Parent nor any of its Subsidiaries
is in violation of any order of any court, governmental authority or arbitration
board or tribunal, or any law, ordinance, governmental rule or regulation to
which Parent or any of its Subsidiaries or any of their respective properties or
assets is subject, except as would not have, individually or in the aggregate, a
Parent Material Adverse Effect. Parent and its Subsidiaries hold all permits,
licenses, variances, exemptions, orders, franchises and approvals of all
governmental authorities necessary for the lawful conduct of their respective
businesses (the "Parent Permits"), except where the failure so to hold would not
have a Parent Material Adverse Effect. Parent and its Subsidiaries are in
compliance with the terms of the Parent Permits, except where the failure so to
comply would not have a Parent Material Adverse Effect. To the knowledge of
Parent, no investigation by any governmental authority with respect to Parent or
any of its Subsidiaries is pending or threatened, other than those the outcome
of which would not have a Parent Material Adverse Effect.

     SECTION 6.6 No Conflict.

          (a) Neither the execution and delivery by Parent and Merger Sub of
     this Agreement, the execution and delivery by Parent of the Stock Option
     Agreements nor the consummation by Parent and Merger Sub of the
     transactions contemplated hereby or thereby in accordance with the terms
     hereof or thereof will: (i) conflict with or result in a breach of any
     provisions of the certificate of incorporation or bylaws of Parent or
     Merger Sub; (ii) violate, or conflict with, or result in a breach of any
     provision of, or constitute a default (or an event which, with notice or
     lapse of time or both, would constitute a default) under, or result in the
     termination or in a right of termination or cancellation of, or give rise
     to a right of purchase under or accelerate the performance required by, or
     result in the creation of any Lien upon any of the properties of Parent or
     its Subsidiaries under, or result in being declared void, voidable, or
     without further binding effect, or otherwise result in a detriment to
     Parent or any of its Subsidiaries under any of the terms, conditions or
     provisions of, any note, bond, mortgage, indenture, deed of trust, license,
     franchise, permit, lease, contract, agreement, joint venture or other
     instrument or obligation to which Parent or any of its Subsidiaries is a
     party, or by which Parent or any of its Subsidiaries or any of their
     properties is bound or affected; or (iii) contravene or conflict with or
     constitute a violation of any provision of any law,

     rule, regulation, judgment, order or decree binding upon or applicable to
     Parent or any of its Subsidiaries, except, in the case of matters described
     in clause (ii) or (iii), as would not have, individually or in the
     aggregate, a Parent Material Adverse Effect.

          (b) Neither the execution and delivery by Parent or Merger Sub of this
     Agreement, the execution and delivery by Parent of the Stock Option
     Agreements nor the consummation by Parent or Merger Sub of the transactions
     contemplated hereby or thereby in accordance with the terms hereof or
     thereof will require any consent, approval or authorization of, or filing
     or registration with, any governmental or regulatory authority, other than
     Regulatory Filings, and listing of the Parent Common Stock to be issued in
     the Merger and upon exercise of the option granted to the Company pursuant
     to the applicable Stock Option Agreement under the rules of the NYSE,
     except for any consent, approval or authorization the failure of which to
     obtain and for any filing or registration the failure of which to make
     would not have a Parent Material Adverse Effect.

     SECTION 6.7 SEC Documents. Parent has made available to the Company each
registration statement, report, proxy statement or information statement (other
than preliminary materials) filed by Parent with the SEC since September 30,
1996, each in the form (including exhibits and any amendments thereto) filed
with the SEC (collectively, the "Parent Reports"). As of their respective dates,
the Parent Reports (i) were prepared in all material respects in accordance with
the applicable requirements of the Securities Act, the Exchange Act, and the
rules and regulations thereunder and (ii) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements made therein, in the light of the
circumstances under which they were made, not misleading except for such

<PAGE>

                                                                         Page 23

statements, if any, as have been modified by subsequent filings with the SEC
prior to the date hereof. Each of the consolidated balance sheets included in or
incorporated by reference into the Parent Reports (including the related notes
and schedules) fairly presents in all material respects the consolidated
financial position of Parent and its Subsidiaries as of its date and each of the
consolidated statements of income, cash flows and changes in stockholders'
equity included in or incorporated by reference into the Parent Reports
(including any related notes and schedules) fairly presents in all material
respects the results of operations, cash flows or changes in stockholders'
equity, as the case may be, of Parent and its Subsidiaries for the periods set
forth therein (subject, in the case of unaudited statements, to (x) such
exceptions as may be permitted by Form 10-Q of the SEC and (y) normal year-end
audit adjustments), in each case in accordance with generally accepted
accounting principles consistently applied during the periods involved, except
as may be noted therein. Except as and to the extent set forth on the
consolidated balance sheet of Parent and its Subsidiaries at September 30, 1997,
including all notes thereto, as of such date, neither Parent nor any of its
Subsidiaries had any liabilities or obligations of any nature (whether accrued,
absolute, contingent or otherwise) that would be required to be reflected on, or
reserved against in, a balance sheet of Parent or in the notes thereto prepared
in accordance with generally accepted accounting principles consistently
applied, other than liabilities or obligations which would not have,
individually or in the aggregate, a Parent Material Adverse Effect.

     SECTION 6.8 Litigation. There are no actions, suits or proceedings pending
against Parent or any of its Subsidiaries or, to Parent's knowledge, threatened
against Parent or any of its Subsidiaries, at law or in equity, or before or by
any federal, state or foreign commission, board, bureau, agency or
instrumentality, that are likely to have, individually or in the aggregate, a
Parent Material Adverse Effect. There are no outstanding judgments, decrees,
injunctions, awards or orders against Parent or any of its Subsidiaries that are
likely to have, individually or in the aggregate, a Parent Material Adverse
Effect.

     SECTION 6.9 Absence of Certain Changes. Since December 31, 1997, there has
not been (i) any event or occurrence that has had or is likely to have a
Material Adverse Effect with respect to Parent, (ii) any material change by
Parent or any of its Subsidiaries, when taken as a whole, in any of its
accounting methods, principles or practices or any of its tax methods, practices
or elections, (iii) any declaration, setting aside or payment of any dividend or
distribution in respect of any capital stock of Parent or any redemption,
purchase or other acquisition of any of its securities, except dividends on the
Parent Common Stock at a rate of not more than $0.115 per share per quarter, or
(iv) any increase in or establishment of any bonus, insurance, severance,

                                       14

deferred compensation, pension, retirement, profit sharing, stock option, stock
purchase or other employee benefit plan, except in the ordinary course of
business.

     SECTION 6.10 Taxes.

          (a) Each of Parent, its Subsidiaries and each affiliated,

<PAGE>

                                                                         Page 24

     consolidated, combined, unitary or similar group of which any such
     corporation is or was a member has (i) duly filed (or there has been filed
     on its behalf) on a timely basis with appropriate governmental authorities
     all Returns required to be filed by or with respect to it, except to the
     extent that any failure to file would not have, individually or in the
     aggregate, a Parent Material Adverse Effect, and (ii) duly paid or
     deposited in full on a timely basis or made adequate provisions in
     accordance with generally accepted accounting principles (or there has been
     paid or deposited or adequate provision has been made on its behalf) for
     the payment of all taxes required to be paid by it, except to the extent
     that any failure to pay or deposit or make adequate provision for the
     payment of such taxes would not have, individually or in the aggregate, a
     Parent Material Adverse Effect.

          (b) (i) The federal income tax returns of Parent and each of its
     Subsidiaries have been examined by the IRS (or the applicable statutes of
     limitation for the assessment of federal income taxes for such periods have
     expired) for all periods through and including September 30, 1993; (ii)
     except to the extent being contested in good faith, all material
     deficiencies asserted as a result of such examinations and any other
     examinations of Parent and its Subsidiaries by any taxing authority have
     been paid fully, settled or adequately provided for in the financial
     statements contained in the Parent Reports; (iii) as of the date hereof,
     neither Parent nor any of its Subsidiaries has granted any requests,
     agreements, consents or waivers to extend the statutory period of
     limitations applicable to the assessment of any taxes with respect to any
     Returns of Parent or any of its Subsidiaries, except that Parent and its
     Subsidiaries have agreed to extend the applicable Federal statutory period
     of limitations to December 31, 1998 for the fiscal year ended October 1,
     1994; (iv) neither Parent nor any of its Subsidiaries is a party to, is
     bound by or has any obligation under any tax sharing, allocation or
     indemnity agreement or any similar agreement or arrangement that would have
     a Parent Material Adverse Effect; and (v) neither Parent nor any of its
     Subsidiaries is a party to an agreement that provides for the payment of
     any amount that would constitute a "parachute payment" within the meaning
     of Section 280G of the Code.

     SECTION 6.11 Employee Benefit Plans.

          (a) Schedule 6.11 of the Parent Disclosure Letter contains a list of
     all U.S. Parent Benefit Plans. The term "Parent Benefit Plans" means all
     material employee benefit plans and other material benefit arrangements,
     including all "employee benefit plans" as defined in ERISA, covering
     employees of Parent and its Subsidiaries. True and complete copies of the
     U.S. Parent Benefit Plans and, if applicable, the most recent Form 5500 and
     annual reports for each such plan have been made available to the Company.

          (b) Except as would not have, individually or in the aggregate, a
     Parent Material Adverse Effect: all applicable reporting and disclosure
     requirements have been met with respect to the Parent Benefit Plans; there
     has been no "reportable event," as that term is defined in section 4043 of
     ERISA, with respect to the Parent Benefit Plans subject to Title IV of
     ERISA; to the extent applicable, the Parent Benefit Plans comply, in all
     material respects, with the requirements of ERISA and the Code, and any
     Parent Benefit Plan intended to be qualified under section 401(a) of the

<PAGE>

                                                                         Page 25

     Code has been determined by the IRS to be so qualified; the Parent Benefit
     Plans have been maintained and operated, in all material respects, in
     accordance with their terms, and there are no breaches of fiduciary duty in
     connection with the Parent Benefit Plans; to Parent's knowledge, there are
     no pending or threatened claims against or otherwise involving any Parent
     Benefit Plan and no suit, action or other litigation (excluding claims for
     benefits incurred in the ordinary course of Parent Benefit Plan activities)
     has been brought against or with respect to any such Parent Benefit Plan;
     all material contributions required to be made as of the date hereof to the
     Parent Benefit Plans have been made or provided for; Parent does not
     maintain or contribute to any material plan or arrangement which provides
     or has any liability to provide life insurance, medical or other employee
     welfare benefits to any employee or former employee upon his retirement or
     termination of employment and Parent has not represented, promised or
     contracted (whether in oral or written form)

                                       15

20

     to any employee or former employee that such benefits would be provided;
     with respect to the Parent Benefit Plans or any "employee pension benefit
     plans," as defined in section 3(2) of ERISA, that are subject to Title IV
     of ERISA and have been maintained or contributed to within six years prior
     to the Effective Time by Parent, its Subsidiaries or any trade or business
     (whether or not incorporated) which is under common control, or which is
     treated as a single employer, with Parent or any of its Subsidiaries under
     sections 414(b), (c), (m), or (o) of the Code, (i) neither Parent nor any
     of its Subsidiaries has incurred any direct or indirect liability under
     title IV of ERISA in connection with any termination thereof or withdrawal
     therefrom; (ii) there does not exist any accumulated funding deficiency
     within the meaning of section 412 of the Code or section 302 of ERISA,
     whether or not waived; and (iii) the actuarial value of the assets equal or
     exceed the actuarial present value of the benefit liabilities, within the
     meaning of section 4041 of ERISA, based upon reasonable actuarial
     assumptions and asset valuation principles; and no prohibited transaction
     has occurred with respect to any Parent Benefit Plan that would result in
     the imposition of any excise tax or other liability under the Code or
     ERISA.

          (c) Neither Parent nor any of its Subsidiaries nor any trade or
     business (whether or not incorporated) which is under common control, or
     which is treated as a single employer, with Parent or any of its
     Subsidiaries under sections 414(b), (c), (m), or (o) of the Code,
     contributes to, or has an obligation to contribute to, and has not within
     six years prior to the Effective Time contributed to, or had an obligation
     to contribute to, a multiemployer plan within the meaning of section 3(37)
     of ERISA. The execution of, and performance of the transactions
     contemplated in, this Agreement will not (either alone or upon the
     occurrence of any additional or subsequent events) constitute an event
     under any benefit plan, policy, arrangement or agreement or any trust or
     loan that will or may result in any payment (whether of severance pay or
     otherwise), acceleration, forgiveness of indebtedness, vesting,
     distribution, increase in benefits or obligations to fund benefits with
     respect to any employee of Parent or any Subsidiary thereof.

     SECTION 6.12 Labor Matters. Neither Parent nor any of its Subsidiaries is
subject to a dispute, strike or work stoppage with respect to any collective
bargaining agreement, contract or other agreement or understanding with a labor
union or labor organization to which it is a party or by which it is bound which
would have a Parent Material Adverse Effect. To Parent's knowledge, there are no
organizational efforts with respect to the formation of a collective bargaining
unit presently being made or threatened involving employees of Parent or any of
its Subsidiaries, except for those the formation of which would not have a
Parent Material Adverse Effect.

     SECTION 6.13 Environmental Matters. Except as would not have, individually
or in the aggregate, a Parent Material Adverse Effect:

          (a) there are not any past or present conditions or circumstances that
     interfere with the conduct of the business of Parent and each of its
     Subsidiaries in the manner now conducted or which interfere with compliance
     with any order of any court, governmental authority or arbitration board or
     tribunal, or any Environmental Law;

          (b) there are not any past or present conditions or circumstances at,
     or arising out of, any current or former businesses, assets or properties
     of Parent or any Subsidiary of Parent, including but not limited to on-site
     or off-site disposal or release of any chemical substance, product or
     waste, which could reasonably be expected to give rise to: (i) liabilities
     or obligations for any cleanup, remediation, disposal or corrective action
     under any Environmental Law or (ii) claims arising for personal injury,
     property damage, or damage to natural resources; and

          (c) neither Parent nor any of its Subsidiaries has (i) received any
     notice of noncompliance with, violation of, or liability or potential
     liability under any Environmental Law or (ii) entered into any consent
     decree or order or is subject to any order of any court or governmental
     authority or tribunal under any Environmental Law or relating to the
     cleanup of any hazardous materials contamination.

                                       16

     SECTION 6.14 Intellectual Property. Except as previously disclosed to the
Company in writing, Parent and its Subsidiaries own or possess adequate licenses
or other valid rights to use all patents, patent rights, trademarks, trademark
rights and proprietary information used or held for use in connection with their
respective businesses as currently being conducted, except where the failure to
own or possess such licenses and other rights would not have, individually or in
the aggregate, a Parent Material Adverse Effect, and there are no assertions or
claims challenging the validity of any of the foregoing which are likely to
have, individually or in the aggregate, a Parent Material Adverse Effect. The
conduct of Parent's and its Subsidiaries' respective businesses as currently
conducted does not conflict with any patents, patent rights, licenses,
trademarks, trademark rights, trade names, trade name rights or copyrights of
others in any way likely to have, individually or in the aggregate, a Parent
Material Adverse Effect. There is no material infringement of any proprietary
right owned by or licensed by or to Parent or any of its Subsidiaries which is
likely to have, individually or in the aggregate, a Parent Material Adverse
Effect. The computer software operated, sold or licensed by Parent that is

                                                                         Page 27

material to its business or its internal operations is capable of providing or
is being or will be adapted, or is capable of being replaced, to provide
uninterrupted millennium functionality to record, store, process and present
calendar dates falling on or after January 1, 2000 in substantially the same
manner and with substantially the same functionality as such software records,
stores, processes and presents such calendar dates falling on or before December
31, 1999, except as would not have a Parent Material Adverse Effect. The costs
of the adaptations and replacements referred to in the prior sentence will not
have a Parent Material Adverse Effect.

     SECTION 6.15 Insurance. Parent and its Subsidiaries maintain insurance
coverage reasonably adequate for the operation of their respective businesses
(taking into account the cost and availability of such insurance).

     SECTION 6.16 No Brokers. Parent has not entered into any contract,
arrangement or understanding with any person or firm which may result in the
obligation of the Company or Parent to pay any finder's fees, brokerage or
agent's commissions or other like payments in connection with the negotiations
leading to this Agreement or the consummation of the transactions contemplated
hereby, except that Parent has retained Merrill Lynch & Co. as its financial
advisor, the arrangements with which have been disclosed in writing to the
Company prior to the date hereof.

     SECTION 6.17 Opinion of Financial Advisor. The Board of Directors of Parent
has received the opinion of Merrill Lynch & Co. to the effect that, as of the
date thereof, the Exchange Ratio is fair to Parent from a financial point of
view.

     SECTION 6.18 Company Stock Ownership. Neither Parent nor any of its
Subsidiaries owns any shares of capital stock of the Company or any other
securities convertible into or otherwise exercisable to acquire capital stock of
the Company.

     SECTION 6.19 Reorganization. Neither Parent nor any of its Subsidiaries has
taken or failed to take any action, as a result of which the Merger would not
qualify as a reorganization within the meaning of section 368(a) of the Code.

     SECTION 6.20 Pooling. Neither Parent nor any of its Subsidiaries has taken
or failed to take any action, as a result of which the Merger would not qualify
as a "pooling of interests" for financial accounting purposes.

     SECTION 6.21 Vote Required. The vote of holders of Parent Common Stock
required by the rules of the NYSE is the only vote of the holders of any class
or series of Parent capital stock necessary to approve the issuance of Parent
Common Stock pursuant to this Agreement and the transactions contemplated
hereby.

     SECTION 6.22 Certain Approvals. The Parent Board of Directors has taken any
and all necessary and appropriate action to render inapplicable to the Merger
and the transactions contemplated by this Agreement and the Stock Option
Agreements the provisions of Section 203 of the DGCL. No other state takeover or

                                       17

business combination statute applies or purports to apply to the Merger or the
transactions contemplated by this Agreement or the Stock Option Agreements.

     SECTION 6.23 Certain Contracts. Neither the Parent nor any of its
Subsidiaries is a party to or bound by any non-competition agreement or any
other agreement or obligation which purports to limit in any material respect
the manner in which, or the localities in which, all or any material portion of
the current business of the Parent and its Subsidiaries, taken as a whole, or
the Company and its Subsidiaries, taken as a whole, is conducted.

                                    COVENANTS

     SECTION 7.1 Conduct of Businesses. Prior to the Effective Time, except as
set forth in the Company Disclosure Letter or as expressly contemplated by any
other provision of this Agreement or the Stock Option Agreements, unless the
Parent or the Company, respectively, has consented in writing thereto, each of
the Company and Parent:

          (a) shall, and shall cause each of its Subsidiaries to, conduct its
     operations according to their usual, regular and ordinary course in
     substantially the same manner as heretofore conducted;

          (b) shall use its commercially reasonable best efforts, and shall
     cause each of its Subsidiaries to use its commercially reasonable best
     efforts, to preserve intact their business organizations and goodwill, keep
     available the services of their respective officers and employees and
     maintain satisfactory relationships with those persons having business
     relationships with them;

          (c) shall not amend its certificate of incorporation or bylaws;

          (d) shall promptly notify the other of any material change in its
     condition (financial or otherwise) or business or any material litigation
     or material governmental complaints, investigations or hearings (or
     communications in writing indicating that such litigation, complaints,
     investigations or hearings may be contemplated), or the breach in any
     material respect of any representation or warranty contained herein;

          (e) shall promptly deliver to the other true and correct copies of any
     report, statement or schedule filed with the SEC subsequent to the date of
     this Agreement;

          (f) shall not (i) except pursuant to the exercise of options,
     warrants, conversion rights and other contractual rights existing on the
     date hereof, or referred to in clause (ii) below and disclosed pursuant to
     this Agreement or in connection with transactions permitted by Section
     7.1(i), issue any shares of its capital stock, effect any stock split or
     otherwise change its capitalization as it existed on the date hereof, (ii)
     grant, confer or award any option, warrant, conversion right or other right
     not existing on the date hereof to acquire any shares of its capital stock
     except (x) the automatic awards to non-employee directors pursuant to the
     Western Atlas Inc. Director Stock Option Plan or the Baker Hughes
     Incorporated Long-Term Incentive Plan, (y) the grant of options to new

<PAGE>

                                                                         Page 29

     employees consistent with past practice or pursuant to contractual
     commitments existing on the date of this Agreement, and (z) the grant of
     options by the Company or Parent prior to the Effective Time in amounts and
     at times consistent with past practice, at exercise prices not less than
     the fair market value of the underlying common stock on the date of grant
     and, in each case, in an amount not to exceed 1.2 million shares of Company
     Common Stock, in the case of the Company, and 120% of the Total Option
     Dollars granted by the Parent, in the case of Parent, in the previous
     fiscal year (provided that for purposes of the foregoing the term "Total
     Option Dollars" shall mean the aggregate number of options granted
     multiplied by the exercise price thereof) and notwithstanding the
     provisions of Section 7.14 or any other provision of this Agreement to the
     contrary, in the event the Company grants options to any of its employees
     prior to the Effective Time, such employees will not be entitled to
     participate in option grants by Parent subsequent to the Effective Time for
     a period at least equal to one year subsequent to the grant of such options
     to Company employees (e.g., if the Company follows its past practice of
     granting options in July and Parent

                                       18

     follows its past practice of granting options in October, such period would
     be 15 months); (iii) increase any compensation or benefits, except in the
     ordinary course of business consistent with past practice, or enter into or
     amend any employment agreement with any of its present or future officers
     or directors, except with new employees consistent with past practice, or
     (iv) adopt any new employee benefit plan (including any stock option, stock
     benefit or stock purchase plan) or amend (except as required by law) any
     existing employee benefit plan in any material respect, except for changes
     which are less favorable to participants in such plans;

          (g) shall not (i) declare, set aside or pay any dividend or make any
     other distribution or payment with respect to any shares of its capital
     stock or (ii) redeem, purchase or otherwise acquire any shares of its
     capital stock or capital stock of any of its Subsidiaries, or make any
     commitment for any such action, except in the case of Parent for the
     declaration and payment of regular, quarterly dividends, consistent with
     past practice, not to exceed $0.115 per share of Parent Common Stock per
     quarter;

          (h) shall not, and shall not permit any of its Subsidiaries to, sell,
     lease or otherwise dispose of any of its assets (including capital stock of
     Subsidiaries) which are material to the Company or Parent, as the case may
     be, individually or in the aggregate, except in the ordinary course of
     business;

          (i) shall not, and shall not permit any of its Subsidiaries to, except
     pursuant to contractual commitments in effect on the date hereof and
     disclosed in the Parent Disclosure Letter or the Company Disclosure Letter,
     as the case may be, acquire or agree to acquire by merging or consolidating
     with, or by purchasing a substantial equity interest in or a substantial
     portion of the assets of, or by any other manner, any business or any
     corporation, partnership, association or other business organization or
     division thereof or otherwise acquire or agree to acquire any assets or

<PAGE>

                                                                         Page 30

     securities in each case (i) for an aggregate consideration for all such
     acquisitions in excess of $100 million (excluding acquisitions approved in
     writing by Parent and the Company) and (ii) where a filing under the HSR
     Act is required, except where Parent and the Company have agreed in writing
     that such action is not likely to (x) have a material adverse effect on the
     ability of the parties to consummate the transactions contemplated by this
     Agreement or (y) delay materially the Effective Time;

          (j) except as may be required as a result of a change in law or in
     generally accepted accounting principles, change any of the accounting
     principles or practices used by it;

          (k) shall, and shall cause any of its Subsidiaries to, use reasonable
     efforts to maintain with financially responsible insurance companies
     insurance in such amounts and against such risks and losses as are
     customary for such party;

          (l) shall not, and shall not permit any of its Subsidiaries to, (i)
     make or rescind any material express or deemed election relating to taxes
     unless it is reasonably expected that such action will not materially and
     adversely affect it (or Parent), including elections for any and all joint
     ventures, partnerships, limited liability companies, working interests or
     other investments where it has the capacity to make such binding election,
     (ii) settle or compromise any material claim, action, suit, litigation,
     proceeding, arbitration, investigation, audit or controversy relating to
     taxes, except where such settlement or compromise will not materially and
     adversely affect it (or Parent), or (iii) change in any material respect
     any of its methods of reporting any item for federal income tax purposes

     regard to a Parent Acquisition Proposal, or (B) prior to the Cutoff Date,
     providing information (pursuant to a confidentiality agreement in

     is superior to the Merger (a "Parent Superior Proposal"), if the Board of
     Directors of Parent, after consultation with its outside legal counsel,
     determines that the failure to do so would be inconsistent with its
     fiduciary obligations.

     Directors, shall recommend approval of such matters subject to the
     determination by the Board of Directors of the Company and the Board of

     fiduciary obligations. Additionally, the Board of Directors of the Company
     or the Board of Directors of Parent may at any time prior to the Effective
     Time withdraw, modify, or change any recommendation and declaration
     regarding this Agreement or the Merger, or recommend and declare advisable
     any other offer or proposal, if in the opinion of such Board of Directors
     after consultation with its counsel the failure to so withdraw, modify, or

          authority or members or their respective staffs on the other hand,
          with respect to this Agreement and the Merger; and

               (vi) furnish the other party with such necessary information and
          reasonable assistance as such other parties and their respective
          affiliates may reasonably request in connection with their preparation

          any governmental or regulatory authorities, including without

          of the HSR Act.

          (b) Without limiting Section 7.5(a), Parent and the Company shall:

               (i) each use its best efforts to avoid the entry of, or to have
          vacated or terminated, any decree, order or judgment that would
          restrain, prevent or delay the Closing, including without limitation
          defending through litigation on the merits any claim asserted in any

               (ii) each take any and all steps necessary to avoid or eliminate
          each and every impediment under any antitrust, competition or trade
          regulation law that may be asserted by any governmental entity with
          respect to the Merger so as to enable the Closing to occur as soon as

provide any information which it reasonably believes it may not provide to the
other party by reason of applicable law, rules or regulations, which constitutes
information protected by attorney/client privilege, or which it is required to

     permitted under applicable law each person who is, or has been at any time
     prior to the Effective Time, an officer or director of the Company (or any
     Subsidiary or division thereof) and each person who served at the request
     of the Company as a director, officer, trustee or fiduciary of another
     corporation, partnership, joint venture, trust, pension or other employee
     benefit plan or enterprise (individually, an "Indemnified Party" and,
     collectively, the "Indemnified Parties") against all losses, claims,
     damages, liabilities, costs or expenses (including attorneys' fees),
     judgments, fines, penalties and amounts paid in settlement in connection
     with any claim, action, suit, proceeding or investigation arising out of or
     pertaining to acts or omissions, or alleged acts or omissions, by them in
     their capacities as such, whether commenced, asserted or claimed before or
     after the Effective Time. In the event of any such claim, action, suit,
     proceeding or investigation (an "Action"), (i) Parent and the Surviving
     Corporation shall pay, as incurred, the fees and expenses of counsel
     selected by the Indemnified Party, which counsel shall be reasonably
     acceptable to the Surviving Corporation, in advance of the final
     disposition of any such Action to the fullest extent permitted by
     applicable law, and, if required, upon receipt of any undertaking required
     by applicable law, and (ii) Parent and the Surviving Corporation will
     cooperate in the defense of any such matter; provided, however, the
     Surviving Corporation shall not be liable for any settlement effected
     without its written consent (which consent shall not be unreasonably
     withheld or delayed), and provided further, that Parent and the Surviving
     Corporation shall not be obligated pursuant to this Section 7.13 to pay the
     fees and disbursements of more than one counsel for all Indemnified Parties
     in any single Action, unless, in the good faith judgment of any of the
     Indemnified Parties, there is or may be a conflict of interests between two
     or more of such Indemnified Parties, in which case there may be separate
     counsel for each similarly situated group.

          (b) The parties agree that the rights to indemnification, including
     provisions relating to advances of expenses incurred in defense of any
     action or suit, in the certificate of incorporation and bylaws of the
     Company and its Subsidiaries with respect to matters occurring through the
     Effective Time, shall survive the Merger and shall continue in full force
     and effect for a period of six years from the Effective Time; provided,
     however, that all rights to indemnification in respect of any Action

<PAGE>

                                                                         Page 39

     pending or asserted or claim made within such period shall continue until
     the disposition of such Action or resolution of such claim.

          (c) For a period of six years after the Effective Time, Parent and the
     Surviving Corporation shall cause to be maintained officers' and directors'
     liability insurance covering the Indemnified Parties who are or at any time
     prior to the Effective Time covered by the Company's existing officers' and
     directors' liability insurance policies on terms substantially no less
     advantageous to the Indemnified Parties than such existing insurance;
     provided, that after the third year after the Effective Time, the Surviving
     Corporation shall not be required to pay annual premiums in excess of 250%
     of the last annual premium paid by the Company prior to the date hereof
     (the amount of which premium is set forth in the Company Disclosure
     Letter), but in such case shall purchase as much coverage as reasonably
     practicable for such amount.

          (d) The rights of each Indemnified Party hereunder shall be in
     addition to any other rights such Indemnified Party may have under the
     certificate of incorporation or bylaws of the Company or any of its
     Subsidiaries, under the DGCL or otherwise. The provisions of this Section
     7.13 shall survive the consummation of the Merger and expressly are
     intended to benefit each of the Indemnified Parties.

          (e) In the event Parent, the Surviving Corporation or any of their
     respective successors or assigns (i) consolidates with or merges into any
     other person and shall not be the continuing or surviving corporation or
     entity in such consolidation or merger or (ii) transfers all or
     substantially all of its properties and assets to any person, then and in
     either such case, proper provision shall be made so that the successors and
     assigns of Parent or the Surviving Corporation, as the case may be, shall
     assume the obligations set forth in this Section 7.13.

     SECTION 7.14 Certain Benefits.

          (a) From and after the Effective Time, Parent and its Subsidiaries
     (including the Surviving Corporation) will honor in accordance with their
     terms the executive, employment and other agreements and arrangements set
     forth in Schedule 7.14(a)(i) of the Company Disclosure Letter or permitted
     by Section 7.1(f) between the Company or its Subsidiaries and certain
     employees and former employees thereof (the "Employment Agreements") and
     certain executives and former executives thereof ("Executive Agreements")
     and all of the Company Benefit Plans and the agreements described in
     Section 7.14(e); provided, however, that nothing herein shall preclude any
     change in any Company Benefit Plan effected on a prospective basis that is
     permitted pursuant to this Section 7.14 and the terms of the applicable
     Benefit Plan; provided, further, that the WAII Retirement/Profit Sharing
     Plan and the WAII Benefits Restoration Plan (and the related cash
     contribution bonus feature) described in Schedule 7.14(a)(ii) of the
     Company Disclosure Letter (the "Profit Sharing Plans") shall be continued
     at least through December 31, 1998 for Company Employees (as defined in
     Section 7.14(d)) without any adverse amendment or modification, the
     Company's Supplemental Retirement Plan and the WAII Executive Retirement

<PAGE>

                                                                         Page 40

     Plan described in Schedule 7.14(a)(iii) of the Company Disclosure Letter
     (the "Retirement Plans") shall be continued through at least December 31,
     1998 without any adverse amendment or modification, the Profit Sharing
     Plans shall be continued without adverse amendment or modification for the
     Western Geophysical division of the Company at least through the end of
     Parent's fiscal year ending in 2001 (and shall be equitably adjusted by
     Parent to appropriately reflect the stand-alone basis of Western
     Geophysical), and the "change of control" provisions in the Profit Sharing
     Plans and the Retirement Plans shall in no event be adversely amended or
     modified. Company performance in respect of calculations made under the
     Profit Sharing Plans for 1998 shall be calculated without taking into
     account any expenses or costs associated with or arising as a result of
     transactions contemplated by this Agreement or any non-recurring charges
     that would not reasonably be expected to have been incurred had the
     transactions contemplated by this Agreement not occurred. Parent hereby
     acknowledges that the consummation of the Merger or stockholder approval of
     the Merger, as applicable, will result in a "change of control" under the
     Executive Agreements and the Employment Agreements, the WAII Supplemental
     Retirement Plan, the WAII Executive Retirement Plan and the other Company
     Benefit Plans set forth in Schedule 7.14(a)(i) of the Company Disclosure
     Letter. Parent shall cause the Surviving Corporation (i) to assume the
     obligations of the Company under the Company Benefit Plans as in effect
     immediately prior to the Effective Time, and to continue to cover under
     such Company Benefit Plans all Company Employees and former Company
     Employees who are participants therein immediately prior to the Effective
     Time and who remain eligible to participate in such Company Benefit Plans
     pursuant to the terms thereof and will provide aggregate employee benefits
     to such Company Employees that are no less favorable than the aggregate
     employee benefits provided them immediately prior to the Effective Time;
     provided, that the Surviving Corporation at its sole option may, except as
     provided herein or by the terms of such plans, amend such plans at any time
     following the Effective Time to provide employee benefits to Company
     Employees which in the aggregate are no less favorable than those
     applicable to similarly situated employees of Parent or, (ii) in lieu
     thereof, except as provided herein or by the terms of the Company Benefit
     Plans, to provide employee benefits to such Company Employees under Parent
     Benefit Plans so that the aggregate employee benefits provided to such
     Company

                                       26

31

     Employees are no less favorable than those that are applicable to similarly
     situated employees of Parent. After the Effective Time, any Company
     Employee who is or becomes entitled to continued medical, dental,
     hospitalization, long-term disability and life insurance coverage pursuant
     to an agreement with the Company set forth in Schedule 7.14(a)(i) of the
     Company Disclosure Letter will be entitled to participate under any
     medical, dental, hospitalization, long-term disability and life insurance
     plan sponsored by Parent or the Surviving Corporation which covers Company
     Employees under the same terms and for payment of the same level of
     premiums as specified in his or her agreement. The Surviving Corporation
     and Parent shall not be obligated hereunder to cover any employee who is
     not a Company Employee or former Company Employee or is not hired or
     offered employment prior to the Effective Time under any employee benefit

<PAGE>

                                                                         Page 41

     plan, program or arrangement. With respect to the Parent Benefit Plans and
     any plans established by the Surviving Corporation, Parent and the
     Surviving Corporation shall grant to all Company Employees, from and after
     the Effective Time, credit for all service with the Company and its
     affiliates and predecessors (and any other service credited by the Company
     under the Company Benefit Plans) prior to the Effective Time for seniority,
     eligibility to participate, eligibility for benefits, benefit accrual and
     vesting purposes. To the extent Parent Benefit Plans provide medical or
     dental welfare benefits, such plans shall waive any pre-existing conditions
     and actively-at-work exclusions with respect to Company Employees (but only
     to the extent such Company Employees were provided coverage under the
     Company Benefit Plans) and shall provide that any expenses incurred on or
     before the Effective Time by or on behalf of any Company Employees shall be
     taken into account under the Parent Benefit Plans for purposes of
     satisfying applicable deductible, coinsurance and maximum out-of-pocket
     provisions.

          (b) The Company acknowledges that the consummation of the Merger will
     generally result in a "change of control" under the executive agreements,
     employment agreements, stock option plan and other employee benefit and
     welfare plans of the Parent and its Subsidiaries containing change of
     control provisions.

          (c) Parent agrees to maintain the Company's severance or termination
     plans and practices and the Company's Corporate Office Severance Plan (the
     "Company Severance Plans") as in effect on the date hereof for a period of
     one year from the Effective Time, and to maintain the Company's Executive
     Severance Plan without amendment except pursuant to its terms, for the
     benefit of Company Employees; provided, however, that any employees covered
     by such plans shall not be covered by the Parent's Severance Plan or
     Executive Severance Plan during such period that such Company's Employees
     are covered under the Company Severance Plans or Executive Severance Plan,
     as applicable.

          (d) For purposes of this Section 7.14, the term "Company Employees"
     shall mean all individuals employed by the Company and its Subsidiaries
     (including those on lay-off, disability or leave of absence, paid or
     unpaid) immediately prior to the Effective Time.

          (e) Parent shall enter into definitive employment agreements prior to
     the Effective Time with the Company Employees set forth on Schedule 7.14(e)
     of the Company Disclosure Letter pursuant to the terms set forth on
     Schedule 7.14(e) of the Company Disclosure Letter. In the event such
     employment agreements are not entered into, the terms set forth on Schedule
     7.14(e) of the Company Disclosure Letter shall govern the employment of
     such Company Employees.

          (f) With respect to the Company's 1995 Incentive Compensation Plan and
     the Company's Individual Performance Award Plan (collectively, the
     "Incentive Plans"), within 30 days following the Effective Time Company
     Employees who remain employed by the Company or its affiliates as of the
     Effective Time shall be paid (to the extent a pro rata bonus is not paid
     under an employment agreement) an amount equal to their maximum potential
     bonus awards under the Incentive Plans, multiplied by a fraction equal to
     the number of days in 1998 through the Effective Time, divided by 365. The

                                                                         Page 42

     remainder of the 1998 maximum potential bonus awards for Company Employees
     shall be paid in the first payroll check in 1999, to those Company
     Employees who are employed with the Parent or any of its affiliates on
     December 31, 1998 or have been terminated prior to such date by the Company
     without cause, or terminated due to death or disability. After the
     Effective Time, any bonuses for periods commencing on or after January 1,
     1999 will be paid under Parent's plans and practices. "Cause" shall mean
     acts of theft,

                                       27

32

     unethical conduct or dishonesty affecting the assets, properties or
     business of the Surviving Corporation or Parent, willful misconduct or
     continued material dereliction of duty after notice has been provided.

          (g) Parent shall not terminate, or permit the Surviving Corporation to
     terminate, other than for Cause, the employment of the individuals set
     forth on Schedule 7.14(g) of the Company Disclosure Letter prior to January
     1, 1999.

     SECTION 7.15 Reorganization; Pooling.

          (a) From and after the date hereof and until the Effective Time, none
     of Parent, the Company, or any of their respective Subsidiaries shall
     knowingly (i) take any action, or fail to take any reasonable action, as a
     result of which the Merger would fail to qualify as a reorganization within
     the meaning of section 368(a) of the Code or (ii) enter into any contract,
     agreement, commitment or arrangement to take or fail to take any such
     action. Each of the parties shall use its reasonable best efforts to obtain
     the opinions of counsel referred to in Sections 8.2(b) and 8.3(b).

          (b) From and after the date hereof and until the Effective Time, none
     of the Company, Parent or any of their respective Subsidiaries shall
     knowingly (i) take any action, or fail to take any reasonable action, that
     would prevent the treatment of the Merger as a "pooling of interests" for
     financial accounting purposes or (ii) enter into any contract, agreement,
     commitment or arrangement to take or fail to take any such action.

          (c) Following the Effective Time, neither Parent nor any of its
     Subsidiaries shall knowingly take any action or knowingly cause any action
     to be taken which would cause the Merger to fail to qualify as a
     reorganization within the meaning of section 368(a) of the Code (and any
     comparable provisions of applicable state or local law).

     SECTION 7.16 Rights Agreement. Prior to the Effective Time, the Board of
Directors of the Company shall take any action (including, if necessary,
amending or terminating (but with respect to termination, only as of immediately
prior to the Effective Time) the Rights Agreement) necessary so that none of the
execution and delivery of this Agreement, the Stock Option Agreements, the
conversion of shares of Company Common Stock into the right to receive Parent
Common Stock in accordance with Article 4 of this Agreement, the issuance of
Company Common Stock upon exercise of the option granted to Parent pursuant to
the applicable Stock Option Agreement, the consummation of the Merger, or any
other transaction contemplated hereby or by the Stock Option Agreements will

cause (i) the Company Rights to become exercisable under the Company Rights
Agreement, (ii) Parent or any of its Subsidiaries to be deemed an "Acquiring
Person" (as defined in the Company Rights Agreement), (iii) any such event to be
an event described in Section 11(a)(ii) or 13 of the Company Rights Agreement or
(iv) the "Shares Acquisition Date" or the "Distribution Date" (each as defined
in the Company Rights Agreement) to occur upon any such event, and so that the
Company Rights will expire immediately prior to the Effective Time. Neither the
Board of Directors of the Company nor the Company shall take any other action to
terminate the Company Rights Agreement, redeem the Company Rights, cause any
person not to be or become an "Acquiring Person" or otherwise amend the Company
Rights Agreement in a manner adverse to Parent.

          (c) None of the parties hereto shall be subject to any decree, order
     or injunction of a court of competent jurisdiction, U.S. or foreign, which

     SECTION 9.2 Termination by Parent or the Company. This Agreement may be
terminated by action of the Board of Directors of Parent or of the Company if:

          (a) the Merger shall not have been consummated by October 31, 1998;

     the party seeking to terminate this Agreement pursuant to this clause (d)
     shall have complied with Section 7.5 and with respect to other matters not

                                                                         Page 48

               (i) by the Company pursuant to Section 9.3(a) fiduciary out; or

               (ii) after the public announcement of a Company Acquisition
          Proposal, by the Company or Parent pursuant to Section 9.2(b) failure
          to obtain Company stockholder approval; or

               (iii) after the public announcement or receipt by the Company's
          Board of Directors of a Company Acquisition Proposal, by Parent
          pursuant to Section 9.4(c) withdrawal of Company recommendation to
          stockholders;

then the Company shall pay Parent a fee of $50 million (subject to reduction
pursuant to Section 9 of the applicable Stock Option Agreement) at the time of
such termination in cash by wire transfer to an account designated by Parent. In
addition, if within one year after such termination, the Company enters into a
definitive agreement with respect to a Company Acquisition or a Company
Acquisition is consummated, in either case with the person making the Company
Acquisition Proposal related to the termination or any affiliate thereof, then
upon the consummation of such Company Acquisition, the Company shall pay Parent
an additional fee of $150 million (subject to reduction pursuant to Section 9 of
the applicable Stock Option Agreement) at the time of such consummation in cash
by wire transfer to an account designated by Parent. For purposes here, "Company
Acquisition" means (i) a consolidation, exchange of shares or merger of the
Company with any person, other than Parent or one of its Subsidiaries, and, in
the case of a merger, in which the Company shall not be the continuing or
surviving corporation, (ii) a merger of the Company with a person, other than
Parent or one of its Subsidiaries, in which the Company shall be the continuing
or surviving corporation but the then outstanding shares of Company Common Stock
shall be changed into or exchanged for stock or other securities of the Company
or any other person or cash or any other property or the shares of Company
Common Stock outstanding immediately before such merger shall after such merger
represent less than 50% of the voting stock of the Company outstanding
immediately after the merger, (iii) the acquisition of beneficial ownership of
50% or more of the voting stock of the Company by any person (as such term is
used under Section 13(d) of the Exchange Act), or (iv) a sale, lease or other
transfer of 50% or more of the assets of the Company to any person, other than
Parent or one of its Subsidiaries.

          (b) If this Agreement is terminated

               (i) by Parent pursuant to Section 9.4(a) fiduciary out; or

               (ii) after the public announcement of a Parent Acquisition
          Proposal, by the Company or Parent pursuant to Section 9.2(c) failure
          to obtain Parent stockholder approval; or

                                       32

37

               (iii) after the public announcement or receipt by Parent's Board
          of Directors of a Parent Acquisition Proposal, by the Company pursuant
          to Section 9.3(c) withdrawal of Parent recommendation to stockholders;

then Parent shall pay the Company a fee of $50 million (subject to reduction
pursuant to Section 9 of the applicable Stock Option Agreement) at the time of

<PAGE>

                                                                         Page 49

such termination in cash by wire transfer to an account designated by the
Company. In addition, if within one year after such termination, Parent enters
into a definitive agreement with respect to a Parent Acquisition or a Parent
Acquisition is consummated, in either case with the person making the Parent
Acquisition Proposal related to the termination or any affiliate thereof, then
upon the consummation of such Parent Acquisition, Parent shall pay the Company
an additional fee of $150 million (subject to reduction pursuant to Section 9 of
the applicable Stock Option Agreement) at the time of such consummation in cash
by wire transfer to an account designated by the Company. For purposes here,
"Parent Acquisition" means (i) a consolidation, exchange of shares or merger of
Parent with any person, other than the Company or one of its Subsidiaries, and,
in the case of a merger, in which Parent shall not be the continuing or
surviving corporation, (ii) a merger of Parent with a person, other than the
Company or one of its Subsidiaries, in which Parent shall be the continuing or
surviving corporation but the then outstanding shares of Parent Common Stock
shall be changed into or exchanged for stock or other securities of Parent or
any other person or cash or any other property or the shares of Parent Common
Stock outstanding immediately before such merger shall after such merger
represent less than 50% of the voting stock of Parent outstanding immediately
after the merger, (iii) the acquisition of beneficial ownership of 50% or more
of the voting stock of Parent by any person (as such term is used under Section
13(d) of the Exchange Act), or (iv) a sale, lease or other transfer of 50% or
more of the assets of Parent to any person, other than the Company or one of its
Subsidiaries.

          (c) In the event of termination of this Agreement and the abandonment
     of the Merger pursuant to this Article 9, all obligations of the parties
     hereto shall terminate, except the obligations of the parties pursuant to
     this Section 9.5 and Section 7.12 and except for the provisions of Sections
     10.3, 10.4, 10.6, 10.8, 10.9, 10.12, 10.13 and 10.14, provided that nothing
     herein shall relieve any party from any liability for any willful and
     material breach by such party of any of its covenants or agreements set
     forth in this Agreement and all rights and remedies of such nonbreaching
     party under this Agreement in the case of such a willful and material
     breach, at law or in equity, shall be preserved.

     SECTION 9.6 Extension; Waiver. At any time prior to the Effective Time,
each party may by action taken by its Board of Directors, to the extent legally
allowed, (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 made to such party contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.
