Item 2. Acquisition or Disposition of Assets.

On August 10, 1998, Baker Hughes Incorporated ("Baker Hughes") completed the
acquisition of Western Atlas Inc. ("Western Atlas") pursuant to the Agreement
and Plan of Merger dated as of May 10, 1998 among Baker Hughes, Baker Hughes
Delaware I, Inc., a direct, wholly owned subsidiary of Baker Hughes ("Merger
Sub"), and Western Atlas, as amended on July 22, 1998 (the "Merger Agreement").
Pursuant to the Merger Agreement, Merger Sub was merged (the "Merger") with and
into Western Atlas, with Western Atlas surviving as a subsidiary of Baker
Hughes. As a result of the merger, each outstanding share of Western Atlas
common stock, par value $1.00 per share ("Western Atlas Common Stock"), has been
converted into the right to receive 2.7 shares of Baker Hughes common stock, par
value $1.00 per share ("Baker Hughes Common Stock"). In the aggregate, Baker
Hughes is issuing approximately 148.6 million shares of Baker Hughes Common
Stock in exchange for the Western Atlas Common Stock. The exchange ratio of 2.7
resulted from the formula in the Merger Agreement that was determined by
negotiations among Baker Hughes and Western Atlas. In addition, as part of the
Merger, Baker Hughes is issuing up to 7.7 million shares of Baker Hughes
Common Stock in exchange for certain rights relating to Western Atlas employee
stock options.

Western Atlas, the common stock of which was previously publicly traded, is a
leading supplier of oilfield services and reservoir information technologies
for the worldwide oil and gas industry. It specializes in land, marine and
transition-zone seismic data acquisition and processing services; well-logging
and completion services; and reservoir characterization and project management
services. Baker Hughes currently intends to continue these business activities
of Western Atlas. There were no material relationships between Baker Hughes and
Western Atlas prior to the consummation of the merger.

    UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS - INTRODUCTION
 
     The following tables set forth certain unaudited pro forma condensed
combined financial information for Baker Hughes giving effect to the Merger
with Western Atlas accounted for as a pooling of interests. 
 
     The unaudited pro forma condensed combined balance sheet was prepared using
the historical balance sheets of Baker Hughes and Western Atlas as of March 31,
1998. The fiscal year ends of Baker Hughes and Western Atlas are September 30
and December 31, respectively. The unaudited pro forma condensed combined
statements of operations for each of the three years in the period ended
September 30, 1997 were prepared using the historical statements of operations
of Baker Hughes for the years ended September 30, 1997, 1996 and 1995 and of
Western Atlas for the years ended December 31, 1997, 1996 and 1995. The
unaudited pro forma condensed combined statement of operations for the six
months ended March 31, 1998 was prepared using the historical statements of
operations of Baker Hughes and Western Atlas for such period. As such, the
results of operations for Western Atlas for the three months ended December 31,
1997 are included in both the unaudited pro forma condensed combined statement
of operations for the six months ended March 31, 1998 and the unaudited pro
forma condensed combined statement of operations for the year ended September
30, 1997. Western Atlas had revenues, income from continuing operations and
diluted income from continuing operations per share for the three months ended
December 31, 1997 of $439.5 million, $31.8 million and $0.57, respectively.
 
     The unaudited pro forma condensed combined financial information was
included for comparative purposes only and does not purport to be indicative of
the results of operations or financial position that actually would have been
obtained if the Merger had been effected at the dates indicated or of the
financial position or results of operations that may be obtained in the future.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS
 
     The Unaudited Pro Forma Condensed Combined Balance Sheet reflects the
conversion of each outstanding share of Western Atlas Common Stock into 2.7
shares of Baker Hughes Common Stock at the date and for the periods presented
and reflects the following reclassifications to give pro forma effect to the
Merger:
 
     (A) To reclassify deferred income taxes from deferred revenue and other
         long-term liabilities.
 
     (B) To reflect the assumed issuance of 148.0 million shares of Baker Hughes
         Common Stock at an exchange ratio of 2.7. 
 
     The Unaudited Pro Forma Condensed Combined Statements of Operations were
prepared to reflect the following reclassifications to give pro forma effect to
the Merger:
 
     (A) To reclassify research and technology expense to cost of services and
         rentals.
 
     (B) To reclassify depreciation, depletion and amortization to the Baker
         Hughes presentation.
 
     In computing Baker Hughes and pro forma combined diluted per share amounts,
the following after tax interest expense amounts related to the Baker Hughes
Liquid Yield Option Notes ("LYONS") are added to income: 1998 -- $3.4 million
and 1996 -- $6.0 million. (The LYONS are anti-dilutive in 1997 and 1995).
Additionally, preferred stock dividends (including the effect of preferred stock
repurchase) of $25.6 million are deducted in 1995 in computing Baker Hughes and
pro forma combined per share amounts available to common stockholders.
 
     It is anticipated that nonrecurring charges in the amount of approximately
$100 million will be expensed in connection with the Merger. Such expenses are
not reflected in the Unaudited Pro Forma Condensed Combined Statements of
Operations.
 
     The Unaudited Pro Forma Condensed Combined Financial Statements do not
purport to indicate what would have occurred had Baker Hughes and Western Atlas
been merged at the beginning of the periods presented, or what results may be in
the future.

                          INDEPENDENT AUDITORS' REPORT


Board of Directors and Shareholders
Western Atlas Inc.

We have audited the accompanying consolidated balance sheets of Western Atlas
Inc. and subsidiaries (the "Company") as of December 31, 1997 and 1996, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the financial statements based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Western Atlas Inc. and subsidiaries
as of December 31, 1997 and 1996, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

                               WESTERN ATLAS INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A:  SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations. Western Atlas Inc. ("WAI" or the "Company") is a leading
supplier of oilfield services and reservoir information technologies for the
worldwide oil and gas industry. The Company provides land, marine, and
transition-zone seismic data acquisition and processing services; well-logging
and completion services; and reservoir characterization and project management
services for a worldwide client base. The Company's principal customers are
private sector and government-owned oil and gas companies, and approximately 68%
of its revenue is generated by activities outside of the United States.

Use of Estimates in the Preparation of Financial Statements. The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenue and expenses for each reporting period. Actual results could differ from
those estimates.

Principles of Consolidation. The consolidated financial statements include those
of the Company, its subsidiaries, and companies in which WAI has a controlling
interest (see Note B.) The equity method is used to account for investments in
companies over which WAI has influence but not a controlling interest. All
material intercompany transactions are eliminated in consolidation.

Earnings Per Share. In February 1997, the Financial Accounting Standards Board
("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 128,
"Earnings per Share." The new standard simplifies the computation of earnings
per share ("EPS") and increases comparability to international accounting
standards. Under SFAS No. 128, "Primary" EPS is replaced by "Basic" EPS, which
excludes dilution and is computed by dividing income available to common
shareholders by the weighted-average number of common shares outstanding for the
period. "Diluted" EPS, which is computed similarly to the former "Fully Diluted"
EPS, reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.

The Company was required to adopt the new standard in its year-end 1997
financial statements. As a result, the Company's reported earnings per share for
1996 and 1995 were restated. The effect of this accounting change on previously
reported EPS data is as follows:

</TABLE>


Cash Equivalents. The Company considers securities purchased within three months
of their date of maturity to be cash equivalents.

Inventories. Inventories are stated at the lower of cost (first-in, first-out
method) or market.

Revenue Recognition. Revenue is recognized when products are shipped or as
services are performed.

Multiclient Seismic Data. Costs incurred in the creation of Company-owned
multiclient seismic data, included in multiclient seismic data and other assets,
are capitalized and amortized over the estimated revenue that the Company
expects to realize from the licensing of such data. Advances received from
customers in payment for specific contracts are included in deferred revenue.



                                      
<PAGE>   7

Research and Technology. Research and technology costs are charged to expense as
incurred. Worldwide expenditures on research and technology activities amounted
to $59.2 million, $54.8 million, and $59.8 million, in the years ended December
31, 1997, 1996, and 1995, respectively.

Property, Plant, and Equipment. Investment in property, plant, and equipment is
stated at cost. Depreciation, computed generally by the straight-line method for
financial reporting purposes, is provided over the estimated useful lives of the
related assets. During the fourth quarter of 1997, the Company extended the
estimated useful lives of certain assets to more closely reflect management's
current estimate of their expected lives. The effect of this change in
accounting estimate resulted in an increase in the Company's earnings from
continuing operations of $2.8 million or $0.05 basic earnings per share, for
1997. The Company uses the full cost method of accounting for its investment in
oil and gas properties. Under this method, the Company capitalizes all
acquisition, exploration, and development costs incurred for the purpose of
finding oil and gas reserves. The Company computes the provision for
depreciation, depletion, and amortization ("DD&A") of oil and gas properties on
a quarterly basis using the unit-of-production method based upon production and
estimates of proved reserve quantities. The full cost accounting rules of the
Securities and Exchange Commission include a reserve value ceiling test which
requires a write-down if the ceiling is exceeded. The Company had write-downs of
$12.5 million and $7.0 million during 1997 and 1996, respectively, due to
ceiling test limitations.

Income Taxes. The Company measures tax assets and liabilities based on a balance
sheet approach. Tax assets and liabilities are stated at the tax rate in effect
when the estimated assets and liabilities will be realized. See Note H for
further discussion.

Concentrations of Credit Risk. Financial instruments that potentially subject
the Company to concentrations of credit risk consist primarily of cash and cash
equivalents and trade receivables. The Company places its cash and cash
equivalents with high-quality financial institutions and limits the amount of
credit exposure with any one institution. Concentrations of credit risk with
respect to trade receivables are limited because a large number of
geographically diverse customers make up the Company's customer base, thus
geographically spreading the trade credit risk.

Translation of Foreign Currencies. Financial statements of foreign subsidiaries
are translated into U.S. dollars based on the functional currency of each
business unit. For units whose local currency is the functional currency, asset
and liability accounts are translated at rates in effect at the balance sheet
date, and revenue and expense accounts are translated at rates approximating the
actual rates on the dates of the transactions. Translation adjustments are
included as a separate component of shareholders' equity. For units that have
the U.S. dollar as the functional currency, inventories, cost of sales,
property, plant, and equipment and related depreciation are translated at
historical rates. Other asset and liability accounts are translated at rates in
effect at the balance sheet date, and revenue and expenses (excluding cost of
sales and depreciation) are translated at rates approximating the actual rates
on the dates of the transactions. Translation adjustments are reflected in the
Consolidated Statements of Income. At December 31, 1997, the U.S. dollar was the
functional currency for substantially all of the Company's foreign operations.

Goodwill and Other Intangibles. For financial statement purposes, goodwill is
generally amortized using the straight-line method over its estimated useful
life, not exceeding 40 years. The Company assesses the recoverability of
goodwill at the end of each fiscal year or more often as circumstances warrant.
Factors considered in evaluating recoverability include management's plan with
respect to the operations to which the goodwill relates, particularly the
historical earnings and projected undiscounted cash flows of such operations.

Dividends. No cash dividends were paid on Common Stock in the years ended
December 31, 1997, 1996, and 1995.

Environmental Costs. Provisions for environmental costs are recorded when the
Company determines its responsibility for remedial efforts and such amounts are
reasonably estimable.

Reclassifications. Certain prior year amounts have been reclassified to conform
to the current year presentation.

New Accounting Standards. In 1997, the FASB issued SFAS No.130, "Reporting
Comprehensive Income," which establishes standards for reporting and display of
comprehensive income and its components. Comprehensive income includes all
changes in equity during a period except those resulting from investments by
owners and distributions to owners. SFAS No. 130 is effective for the Company
beginning in 1998 and is expected to impact the Company's reporting of the
excess of additional pension liability over recognized prior service cost.
Currently, these items are included as components of Shareholders' Equity.


                                      
<PAGE>   8

Also during 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information," which establishes new requirements on
the reporting of information about operating segments, products and services,
geographic areas, and major customers. In February 1998, SFAS No. 132,
"Employers' Disclosures about Pensions and Other Postretirement Benefits," was
issued which revises required disclosures relating to pensions and
postretirement benefit plans. SFAS No. 131 and 132 are effective for the Company
beginning in 1998. The Company will analyze these pronouncements during 1998 to
determine what, if any, additional disclosures will be required thereunder.

NOTE B:  DISCONTINUED OPERATIONS

On May 4, 1997, the Company's Board of Directors approved, in principle, a plan
to distribute (the "Spin-off") to WAI shareholders all of the outstanding common
stock of UNOVA, Inc. ("UNOVA"), a wholly owned subsidiary of WAI. UNOVA was
subsequently organized to own and conduct all of WAI's industrial automation
systems operations, which include its automated data collection and
manufacturing systems businesses. Pursuant to the Spin-off, on October 31, 1997
each WAI shareholder of record on October 24, 1997 received an equivalent number
of shares of UNOVA common stock. The distribution of such stock was structured
to be tax-free to WAI and its shareholders. Concurrent with the Spin-off, UNOVA
repaid WAI for intercompany indebtedness totaling $230 million. WAI used the
funds to repay certain short-term borrowings.

In connection with the Spin-off, the Consolidated Financial Statements of WAI
and related notes thereto were restated to present the operations of UNOVA as
discontinued. Income (loss) from discontinued operations included interest
expense allocated on the basis of debt levels assumed in the Spin-off. Corporate
general and administrative costs of the Company were not allocated to UNOVA for
any of the periods presented.

Discontinued operations of UNOVA for the ten months ended October 31, 1997 and
the years ended December 31, 1996 and 1995 are as follows:

Assuming the Spin-off had occurred on January 1, 1997, the pro forma effect on
the Company's earnings from continuing operations is the reduction of general
and administrative expenses of $9.9 million, net of tax, and Spin-off related
costs of $5.0 million, net of tax. These amounts would result in an increase of
$.28 in basic earnings per share on a pro forma basis.

NOTE C:  BUSINESS ACQUISITIONS, INVESTMENTS, AND DISPOSITIONS

Acquisitions and Investments. The Company made several acquisitions and
investments during the year ended December 31, 1997. In May 1997, the Company
acquired Sungroup Energy Services Company, a Canadian well-logging, production
testing, and completion services provider. During the fourth quarter of 1997,
the Company completed the following acquisitions: Geosignal, Inc., a seismic
data processing company; Seismic Resources, Inc., a provider of nonexclusive
seismic surveys; and ParaMagnetic Logging, Inc., a well-logging research
company. These acquisitions were made using Company common stock. Also in the
fourth quarter of 1997, the Company used cash to purchase Heartland Kingfisher
Inc., a Canadian well-logging company. In 1995, the Company used cash to
purchase 50% of PetroAlliance Services Company, Ltd., which offers seismic,
well-logging, and integrated project services to local and international oil
companies operating in the former Soviet Union.

The purchase method of accounting was used to record all of these acquisitions.
Their results of operations are included in the Consolidated Statements of
Income from the acquisition dates. These acquisitions and several smaller
acquisitions in 1995 and 1996 are integral to the Company's goals, though not
material in the aggregate to the Company's consolidated financial statements in
any one year.

The Company acquired Norand Corporation ("Norand") on March 3, 1997, and United
Barcode Industries ("UBI") on April 4, 1997. These companies were integrated
into the Company's industrial automation systems operations and included in the
Spin-off. Both transactions were funded using a combination of committed credit
facilities, short-term uncommitted credit lines and excess cash. The purchase
method of accounting was used to record these acquisitions and, accordingly, the
acquisition costs (approximately $280 million and $107 million for Norand and
UBI, respectively) were allocated to the net assets acquired based upon their
relative fair values. Such allocation assigned $203 million to in-process
research and development activities, which was expensed in accordance with FASB
Interpretation No. 4 during the second quarter.

The Company also acquired the remaining 51% of Honsberg, a German machine tool
maker, in the second quarter of 1997. The original 49% of Honsberg was acquired
during 1995. In September 1997, the Company acquired the stamping, engineering,
and prototyping division of Modern Prototype Company. These companies were also
included in the Spin-off.

Dispositions. The assets of the Company's seismic equipment manufacturing
operations were sold during the second quarter of 1995 for approximately $122
million in cash. As part of the sales agreement, the Company entered into a
commitment to purchase from the buyer $350 million of seismic and related
equipment. The remaining equipment purchase commitment is approximately $67
million as of December 31, 1997. The excess of the sales price over the net book
value of the assets sold was deferred and is amortized as the Company purchases
equipment from the buyer.

</TABLE>

In July 1997, the Company commenced a short-term commercial paper ("CP") program
providing for the issuance of up to $400 million in aggregate maturity value of
commercial paper at any given time. As of December 31, 1997, outstanding
commercial paper borrowings totaled $135.3 million and interest rates on such
borrowings ranged from 5.9% to 6.25% with an effective weighted average interest
rate of 6.05%. The CP program is secured by committed credit facilities with a
group of banks that provide for $400 million in long-term committed credit
reduced by the amount outstanding under the CP program. No amounts were
outstanding under the long-term committed credit facilities at December 31, 1997
except those committed in support of the CP program. At December 31, 1997, $300
million in commercial paper and short-term obligations was reclassified as
long-term debt as the Company has the ability and intent to refinance such
obligations on a long-term basis utilizing existing credit facilities.

The Company maintains off-balance-sheet guarantees and letter-of-credit
agreements. At December 31, 1997, the face values of these agreements totaled
$156 million of which $84 million was related to contracts to build two seismic
vessels. (See "Financial Instruments" below and Note K: "Litigation, Commitments
and Contingencies.") The remaining $72 million of credit arrangements are
generally related to guarantees of future performance on contracts.

At December 31, 1997, the Company was in compliance with its various debt
covenants, which relate to the Company's incurrence of debt, mergers,
consolidations, and sale of assets and require the Company to satisfy certain
ratios related to tangible net worth, debt-to-equity and interest coverage.

Aggregate Maturities of Debt

Notes payable and long-term obligations at December 31, 1997 mature as follows,

Financial Instruments
   
The Company uses forward contracts for the purpose of reducing its exposure to
adverse fluctuations in foreign exchange and interest rates. While these hedging
instruments are subject to fluctuations in value, such fluctuations are
generally offset by the value of the underlying exposure being hedged. The
Company is not a party to leveraged derivatives and does not hold or issue
financial instruments for speculative purposes.

Foreign Currency Management - From time to time, the Company enters into foreign
currency forward contracts to hedge anticipated and firmly committed foreign
currency transactions. At December 31, 1997, the Company had entered into
foreign currency forward contracts with notional amounts of $88.9 million to
primarily hedge the commitment to purchase two seismic vessels in 1999. The
notional amounts are used to express the volume of these transactions and do not
represent exposure to loss. The carrying value of the contracts was not
significant. The fair value of the contracts, based on year-end quoted rates for
purchasing contracts with similar terms and maturity dates, approximated
carrying value and was also not significant. Foreign currency gains and losses
for such purchases are deferred as part of the basis of the assets. The
counterparties to the Company's forward contracts are major financial
institutions. The credit ratings and concentration of risk of these financial
institutions are monitored on a continuing basis and, in management's opinion,
present no significant credit risk to the Company.

Interest Rate Management - The Company periodically enters into various
financial instruments to manage its interest rate exposure. At December 31,
1997, the Company did not have any outstanding interest rate swap agreements.

The following table presents the carrying amounts and estimated fair values of
the Company's financial instruments at December 31, 1997 and 1996:

</TABLE>


The following methods and assumptions were used to estimate the fair value of
the financial instruments summarized in the table above. The carrying values of
accounts receivable, accounts payable, and payrolls and related expenses
included in the accompanying Consolidated Balance Sheets approximated market
value at December 31, 1997 and 1996.

Cash and cash equivalents - The carrying amounts approximated fair value due to
the short maturity of these instruments.

Long-term debt - The fair values of the 7.875% notes and the 8.55% debentures
were based on the quoted market price for similar issues. The carrying amount of
the commercial paper, short-term notes payable, and other debt approximated fair
value due to the short maturities and because the interest rates were reflective
of market rates.

Stock Option Plans

The Company has a stock option plan, which provides for the grant of incentive
awards to officers and other key employees. Incentive awards are granted in the
form of stock options at a price equal to the fair market value of the Company's
common stock on the date of grant, at terms not exceeding 10 years. The Company
also has a directors' stock option plan that provides for the grant of stock
options to the Company's nonemployee directors. Under this plan, stock options
are granted annually at the fair market value of the Company's common stock on
the date of grant at terms not exceeding 10 years. The number of options so
granted annually is fixed by the plan. Options granted under the directors'
stock option plan become fully exercisable on the first anniversary of their
grant. Under these plans, there were a total of 1,818,390 and 1,098,528 shares
subject to options which were exercisable as of December 31, 1997 and 1996,
respectively, and 1,142,464 shares available for grant as of December 31, 1997.

In connection with the Spin-off, all employee and director options outstanding
immediately prior to the Spin-off were adjusted by increasing the number of
shares subject to the option and decreasing the exercise price per share so as
to preserve the difference between the aggregate exercise price of the option
and the aggregate market value of the shares subject to the option. Grants in
1997 include options to acquire 484,379 common shares with a weighted average
exercise price of $39.42 which were acquired in the acquisition of Norand.

</TABLE>


The fair value of stock options granted during 1997 and 1996 were $26.3 million
and $12.8 million, respectively. The fair value of each stock option grant is
estimated on the date of grant using the Black-Scholes option pricing model with
the following weighted-average assumptions used for grants in 1997 and 1996,
respectively: risk-free interest rates of 6.3% and 6.4%, expected life of five
years for both years; and expected volatility of 33% and 26%, determined from
historical stock price fluctuations. There is no assurance that the assumptions
used in determining the fair values of stock options will prove true in the
future. The actual value of the options depends on several factors, including
the actual market price of the common stock on the date of exercise. Changes in
any of these factors as well as fluctuations in the market price of the
Company's common stock will cause the actual value of these options to vary from
the theoretical value indicated above.

Employee Stock Purchase Plan

Under the 1996 Employee Stock Purchase Plan, the Company is authorized to sell
up to 2.5 million shares of common stock to eligible full-time employees of WAI
and participating subsidiaries. At each semi-annual offering period, employees
can choose to have up to 8% of their annual earnings withheld to purchase the
Company's common stock up to a maximum amount of $21,250 per calendar year. The
purchase price of the stock is 85% of the lower of its beginning-of-period or
end-of-period market price. The Company sold 95,129 and 36,975 shares under the
Plan in 1997 and 1996, respectively, with approximately 20% of eligible
employees participating each year. The weighted-average fair value of purchase
rights granted in 1997 and 1996 was $1,687,000 and $471,800, respectively. The
fair value of the stock purchase rights was determined using the same method and
parameters for stock option grants described above, except for the use of an
expected life equal to the purchase window period. As previously noted, the
actual value of purchase rights may vary from the theoretical value determined
using the Black-Scholes option pricing model.

Pro Forma Compensation Disclosure

The Company accounts for its stock-based compensation plans in accordance with
Accounting Principles Board Opinion No. 25, under which no compensation cost is
recognized for stock option awards or grants of stock purchase rights. Had
compensation cost for these plans been determined consistent with SFAS No. 123,

The actual pro forma impact on net income and earnings per share may differ from
the theoretical valuation determined using the Black-Scholes option pricing
model due to factors previously noted. Further, the SFAS No. 123 method of
accounting was not applied to options granted prior to January 1, 1995,
therefore, the resulting pro forma compensation cost may not be representative
of that to be expected in future years.

Shareholder Rights Plan

On August 17, 1994, the Company's Board of Directors adopted a Share Purchase
Rights Plan and, in accordance with such Plan, declared a dividend of one
preferred share purchase right for each outstanding share of Company common
stock, payable August 31, 1994 to shareholders of record on that date. In the
event that a party acquires more than 15% of the Company's then outstanding
Common Stock, the Plan will cause substantial dilution to a party that attempts
to acquire the Company in a manner or on terms not approved by the Board of
Directors, except pursuant to an offer conditioned on a substantial number of
rights being acquired.

The rights, which do not have voting rights and are not entitled to dividends
until such time as they become exercisable, expire on August 2004.

NOTE H:  TAXES ON INCOME

The components of taxes on income from continuing operations consist of the
following provisions (benefits):

NOTE I:  PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

Pension Benefits

The Company has retirement and pension plans that cover most of its regular,
full-time employees. Most of the Company's U.S. employees are covered by a
defined contribution plan. The Company contributes an amount based on its
consolidated pretax earnings in accordance with the provisions of such plan.
This plan includes a voluntary savings feature that is intended to qualify under
Section 401(k) of the Internal Revenue Code and is designed to enhance the
retirement programs of participating employees. Under this feature, the Company
matches up to 67% of a certain portion of participants' contributions.

Certain subsidiaries of the Company also have retirement and savings plans for
eligible employees located outside the United States. The pension liabilities
and their related costs are computed in accordance with the laws of the
individual nations and appropriate actuarial practices.

The Company has a defined benefit retirement plan for its directors whereby
retired directors are paid an amount equal to active directors for a specified
period of time after retirement. In the event of a change in control in the
Company, directors receive a lump sum distribution of these payments.

U.S. Pension Plans

A summary of the components of net periodic pension cost for the U.S. defined
benefit plans and defined contribution plans for the years ended December 31,
1997, 1996, and 1995, is as follows:

Actuarial assumptions for the Company's U.S. defined benefit plans included an
expected long-term rate of return on plan assets of 8.00% and 9.25% for fiscal
years 1997 and 1996, respectively. The weighted-average discount rate used in
determining the actuarial present value of the projected benefit obligation was
7.0% and 7.5% at December 31, 1997 and 1996, respectively. The rate increase in
future compensation levels was 5% at December 31, 1997 and 1996. Pursuant to the
provisions of SFAS No. 87, "Employers' Accounting for Pensions," the Company
recorded in other noncurrent liabilities an additional minimum pension liability
adjustment of $5.4 million as of December 31, 1997. This additional liability
represented the amount by which the accumulated benefit obligation exceeded the
accrued amounts previously recorded. As there were no previously unrecognized
prior service costs at December 31, 1997, the full amount of the adjustment, net
of the related deferred tax benefit, was recorded as a reduction of
stockholders' equity of $3.5 million.

The following table sets forth the amounts recognized in the Company's balance
sheet at December 31, 1997 and 1996 for the Company's U.S. defined benefit
plans. All of the plans are unfunded.

Non-U.S. Pension Plans

For the principal non-U.S. pension plans located in the United Kingdom, the
weighted-average discount rate used was approximately 8.5% at December 31, 1997.
The rate of increase in future compensation used was approximately 5.5% and the
rate of return on assets was 9.0% at December 31, 1997.

Pension costs for non-U.S. plans were not material for any of the periods
presented herein. The actuarial present value of projected benefits at December
31, 1997 was $25.8 million compared with net assets available for benefits of
$33.2 million.

Other Postretirement Benefits

In addition to pension benefits, certain of the Company's U.S. employees are
covered by postretirement health care and life insurance benefit plans. These
benefit plans are unfunded.

The net periodic postretirement benefit costs were not material for any of the
periods presented herein. The accumulated benefit obligation at December 31,
1997 was $6.1 million, of which $1.9 million was attributable to retirees and
$4.2 million to other active plan participants. The accumulated benefit
obligation for continuing operations at December 31, 1996 was $3.8 million, of
which $1.4 million was attributable to retirees and $2.4 million was
attributable to active plan participants.

Actuarial assumptions used to measure the accumulated benefit obligation include
a discount rate of 7.0% and 7.5% at December 31, 1997 and 1996, respectively.
The assumed health care cost trend rate for fiscal 1997 was 11.0% and is
projected to decrease over 20 years to 5.4%. The effect of a
one-percentage-point increase in the assumed health care cost trend rate on the
service cost and interest cost components of the net periodic postretirement
benefit cost is not material. A one-percentage-point increase in the assumed
health care cost trend rate on the accumulated benefit obligation results in an
increase of approximately $0.3 million.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                       THREE MONTHS ENDED MARCH 31, 1998

1.   GENERAL

     The amounts included in this report are unaudited; however, in the opinion
     of the management of Western Atlas Inc. (the "Company"), all adjustments
     necessary for a fair presentation of the Company's consolidated financial
     position as of March 31, 1998 and its results of operations and cash flows
     for the three months ended March 31, 1998 and 1997 are included. Certain
     information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles are condensed or omitted pursuant to the rules and regulations
     of the Securities and Exchange Commission. These condensed consolidated
     financial statements should be read in conjunction with the Company's 1997
     Annual Report on Form 10-K (as amended by Form 10-K/A) prepared in
     accordance with generally accepted accounting principles. The results of
     operations for the three months ended March 31, 1998 are not necessarily
     indicative of the results to be expected for the entire year.

     In June 1997, the Financial Accounting Standards Board ("FASB") issued
     Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
     Comprehensive Income," which established standards for reporting and
     display of comprehensive income and its components. Comprehensive income
     includes all changes in equity during a period except those resulting from
     investments by owners and distributions to owners. SFAS No. 130 was adopted
     by the Company in 1998. Comprehensive income as determined under this
     standard was $28.1 million for the three months ended March 31, 1997; there
     was no effect for the three months ended March 31, 1998.

2.   DISCONTINUED OPERATIONS

     On October 31, 1997, the Company distributed all the shares of UNOVA, Inc.
     ("UNOVA"), its then wholly owned industrial automation systems subsidiary,
     as a stock dividend to the Company's shareholders (the "Spin-off"). The
     operations of UNOVA for the three months ended March 31, 1997 are
     classified as discontinued operations in the Company's Condensed
     Consolidated Financial Statements. For periods prior to the Spin-off, total
     cash, debt, and related net interest expense were allocated based on the
     capital needs of the operations. All corporate general and administrative
     costs of the Company are included in continuing operations and no
     allocation was made to UNOVA for any of the periods presented.

     Discontinued operations of UNOVA for the three months ended March 31, 1997
     are as follows (in thousands):

3. EARNINGS PER SHARE

   For the year ended December 31, 1997, the Company adopted Statement of
   Financial Accounting Standards ("SFAS") No. 128, titled "Earnings per
   Share," which simplifies the computation of earnings per share ("EPS") and
   increases comparability to international accounting standards. The effect of
   this accounting change on previously reported EPS data for the three months
   ended March 31, 1997 is as follows:

5. DEBT

   The Company has a short-term commercial paper ("CP") program which allows
   the Company to borrow up to $400 million in aggregate maturity value of
   commercial paper, with maturities up to 270 days. At March 31, 1998, $201.9
   million was borrowed under the CP program at annual interest rates
   approximating 5.69%. In connection with the CP program, the Company agreed
   to maintain committed credit facilities with a group of banks that provide
   for $400 million in long-term committed credit. At March 31, 1998, there
   were no amounts outstanding under the long-term committed credit facility.
   At March 31, 1998, $300 million in commercial paper and short-term
   obligations was reclassified to long-term debt as the Company has the
   ability and intent to refinance such obligations on a long-term basis.

6. SUBSEQUENT EVENTS

   On April 1, 1998, the Company acquired all the outstanding stock of WEDGE 
   DIA-LOG, Inc. ("WEDGE") for approximately $218 million in cash (the "WEDGE
   Acquisition"). In connection with the WEDGE Acquisition, the Company repaid
   approximately $33 million of WEDGE's indebtedness. WEDGE specializes in
   cased-hole logging and pipe recovery services.

   In April 1998, the Company acquired 3-D Geophysical, Inc. ("3-D
   Geophysical") for $9.65 cash per share for an aggregate consideration of
   approximately $115 million. 3-D Geophysical is a supplier of primarily
   land-based seismic data acquisition services. In addition, the holders of
   unexercised options to acquire 3-D Geophysical common stock will receive an
   aggregate of approximately $3 million. 3-D Geophysical also had
   approximately $11 million in outstanding indebtedness which was repaid by
   the Company.

   The purchase method of accounting was used to record both of these
   acquisitions. Unaudited pro forma information related to these acquisitions
   is not included as the impact of these acquisitions is not material.

   On May 10, 1998, Baker Hughes Incorporated ("Baker Hughes") and the Company
   entered into a definitive merger agreement (the "Merger Agreement") which
   provides for the Company to be merged (the "BHI Merger") with a subsidiary
   of Baker Hughes. The Merger Agreement provides that the Company's
   shareholders are to receive 2.4 shares of newly issued Baker Hughes common
   stock for each Western Atlas common share, subject to adjustment. The
   transaction is expected to be accounted for as a pooling of interests and is
   expected to be tax-free to the Company's shareholders. It is anticipated
   that the transaction will be completed by the end of September 1998 and is
   subject to shareholder and regulatory approvals, including expiration of the
   applicable waiting period under the Hart-Scott-Rodino Act, and other
   customary closing conditions.
