ITEM 1.  BUSINESS
 
    Western Atlas Inc. (the "Company" or "WAI") operates in two principal
business segments: "Oilfield Services," where the Company participates in the
high-technology information services sector as one of the largest providers
worldwide; and "Industrial Automation Systems," where the Company is a major
global supplier of integrated manufacturing systems and automated data
collection systems. For the year ended December 31, 1996, Oilfield Services
generated revenues and operating profits of $1,402.9 million and $172.9 million,
respectively, and Industrial Automation Systems produced revenues and operating
profits of $1,179.9 million and $101.1 million, respectively. See Note K to the
consolidated financial statements for financial information by industry segment
and by geographical area.
 
    Information related to business acquisitions, investments and dispositions
is set forth in Note B to the consolidated financial statements.
 
OILFIELD SERVICES
 
    Western Atlas International, Inc. ("WAII" or "Oilfield Services"), operates
in the high-technology information services sector of the oil industry. WAII
specializes in land, marine and transition-zone seismic surveys; well-logging
and completion services; and reservoir description and management.
 
    Oilfield Services operates through three divisions: Western Geophysical,
Western Atlas Logging Services and E&P Services. These divisions are focused on
the development and application of advanced data acquisition and processing
techniques to help evaluate the oil and gas producing potential of the earth's
sedimentary basins, locate productive zones, reduce drilling costs by minimizing
the number of wells necessary to explore and develop reservoirs, and improve
production output from reservoirs for petroleum industry customers worldwide.
Increasing emphasis is being placed on the fundamental interrelationship of
seismic and well-logging data. New techniques are being applied to integrate
these data, providing a comprehensive reservoir analysis for customer
technologists, from geophysicists and geologists, to production engineers.
 
    In June 1995, the Company acquired 50% of PetroAlliance Services, a joint
venture offering seismic, well-logging, and integrated project services to local
and international oil companies operating in the Former Soviet Union ("FSU"). In
1996 the company acquired several small technology companies to expand its
reservoir characterization capabilities in seismic and well-logging.
 
    The nature of the industry and diverse market environments carry certain
inherent risks for any company in this business. Oilfield Services recognizes
that it must adjust to fluctuations in foreign currencies. It is conducting
field operations in regions that are politically unstable. It is obliged to
establish its own operational infrastructure in certain developing areas of the
world, and its business is necessarily capital intensive, particularly during
growth cycles.
 
    MARKETS AND CUSTOMERS
 
    The market for Oilfield Services' products and services is the worldwide
petroleum industry, which includes private, public and government-owned
companies. Customers number in the hundreds and range from large integrated oil
companies to small independents. No single customer represents as much as 10% of
Oilfield Services' revenues.
 
    Activity in the oilfield services market is largely determined by oil
companies' evaluation of the market price of oil and gas, the levels of reserves
in specific geographical regions and, as it relates to government-sponsored oil
and gas exploration, the budgetary priorities of the relevant governments.
 
                                       1

ITEM 1.  BUSINESS (CONTINUED)
 
    COMPETITION
 
    Competition in the high-technology sector of the oilfield services market
ranges from a few larger companies with a broad spectrum of services, to smaller
companies targeting narrow market segments. There are five major participants in
the market, Schlumberger, Baker Hughes, Dresser Industries, Halliburton and
WAII, each of which has annual revenues in excess of $1 billion. The Company is
the smallest of these five participants, measured by revenues, but one of the
two largest providers of oilfield information technology. The number of smaller
competitors is in the hundreds. The more significant of the smaller competitors
include Petroleum Geo Services in marine seismic, Compagnie Generale de
Geophysique and Veritas DGC in land seismic, and Computalog in well-logging.
Projects are won in the marketplace on the basis of price, quality and service.
 
    The large oil companies, which are Oilfield Services' customers, also retain
certain in-house capabilities for various oilfield services. However, more of
such services are being outsourced and the Company believes this trend will
continue.
 
INDUSTRIAL AUTOMATION SYSTEMS
 
    The Company is an international supplier of industrial automation
technologies and products, including integrated manufacturing systems and
automated data collection systems. The Company supplies machining, body and
assembly and precision grinding systems for the automotive industry, and
automated data collection systems for manufacturing, governmental, logistics and
distribution applications. Overall, customers of Industrial Automation Systems
are the automotive and off-road vehicle industries, wholesale and distribution
companies, manufacturing industries and government agencies.
 
    During 1995, the Company acquired 49% of Honsberg, a German machine tool
maker; and Cranfield Precision Engineering, a grinding technology company
located in the United Kingdom.
 
    The Company sold its Material Handling Systems operations in November of
1996. While the division had achieved improved performance, its activities were
not a core business of the Company.
 
    The Company markets its systems and services primarily under the
well-established brand names: Lamb Technicon, Landis, Landis Lund, Gardner,
CITCO and Intermec.
 
    The Company, through its Lamb Technicon operations ("Lamb"), designs and
installs integrated manufacturing systems for high-volume production, and
flexible machining systems for medium-volume applications, primarily for the
world's automotive and off-road vehicle industries. These systems are used in
the production of powertrains - primarily car engines and transmissions. Lamb is
also a supplier of welding and assembly systems for car bodies, engine and other
powertrain components.
 
    Through its Landis, Gardner and CITCO operations, the Company develops and
produces precision grinding systems, tools and equipment for the automotive
manufacturing market. These operations concentrate primarily on the application
of precision cylindrical and disc-grinding technologies for medium-and
high-volume production of car engine and transmission parts.
 
    The Company's automated data collection business is conducted by Intermec.
Automated data collection systems are used to gather and organize data, and then
transmit selected information from various locations to a user's central
computer or retrieval system. Such products are employed in a growing number of
applications worldwide to improve productivity, efficiency and accuracy in data
collection. Automated data collection systems are typically used to track
personnel, parts or products and transactions through manufacturing,
distribution and other processes. Technologies used for automated data
collection include bar code printers, laser scanners and other imaging methods,
as well as hand-held computers and wireless radio frequency ("RF") transmission
devices. Bar coding is currently the most widely used
 
                                       2
<PAGE>
ITEM 1.  BUSINESS (CONTINUED)
 
technology for automated data collection, providing a cost-effective solution
and a rapid return on investment for customers.
 
    Subsequent to fiscal year end 1996, the Company acquired Norand Corporation
("Norand") on March 3, 1997. Norand's fiscal 1996 revenues were approximately
$235 million. Norand's leadership in mobile computing, wireless data
transmission, pen-based systems, inventory tracking and route accounting
directly complements WAI's position in the industrial, governmental and
distribution markets for automated data collection.
 
    MARKETS AND CUSTOMERS
 
    More than half of Industrial Automation Systems' revenues are generated by
the worldwide automotive industry, which purchases integrated manufacturing
systems, including machining, body and assembly, grinding systems and stand
alone machines to integrate into their own production process. Among customers
for such equipment, U.S. and Canadian auto producers currently account for more
than 70% of integrated manufacturing systems sales, and manufacturers in Europe
account for about 20%. The remainder of sales represents products exported from
the Company's production facilities, mostly for installation in Latin America,
India and China. Current customers include U.S. based Chrysler, Cummins, Ford,
General Motors, Detroit Diesel and Navistar; in foreign markets: Yuchai Diesel,
China; Tata (Telco), India; and major Western European auto manufacturers,
including BMW/Rover, Fiat, Mercedes Benz, Jaguar, Peugeot, Renault and
Volkswagen.
 
    Intermec's market is extensive because automated data collection represents
a technology that can be utilized by a company of any size, and small systems
can be installed at very low costs. Intermec uses two different marketing
channels: Intermec's direct organization, which serves customers from offices
throughout North America and in several European countries; and an indirect
sales channel that includes long-time exclusive relationships with international
value-added distributors and vertical marketing affiliations with a large number
of value-added resellers in the U.S. and abroad.
 
    COMPETITION
 
    Strong competition exists both in the domestic and international markets for
the products and services of the Industrial Automation Systems segment. Products
are sold and projects are won in the marketplace based on price, quality,
technology and service. The Company's competitors range in size from those with
capital resources comparable to or greater than WAI's, to companies that are
significantly smaller.
 
    The market for high-volume production systems for engines and transmissions
in North America and Europe is divided among approximately 10 major competitors
and numerous smaller participants. Management estimates that the Company
commands the largest share of the U.S. market. Major participants in these
businesses include Giddings & Lewis, Inc.'s Integrated Automation Systems,
Thyssen Production Systems, Ingersoll Milling and Grob-Werke Gmbh. & Co. KG in
high-volume powertrain production systems.
 
    The market for automated data collection systems is highly competitive and
fragmented. Based on independent market surveys, management believes that
Intermec is among the larger of the participants in this industry. Principal
competitors in the automated data collection industry include Symbol
Technologies, Inc., Telxon Corporation and Zebra Technologies Corporation, as
well as numerous systems integrators.
 
METHODS OF DISTRIBUTION
 
    The Company principally markets its products and services globally through
the headquarters and branch offices of its various operations and through
independent distributors and resellers. In general,
 
                                       3
<PAGE>
ITEM 1.  BUSINESS (CONTINUED)
 
each of the Company's operations is responsible for selecting, implementing and
maintaining its own marketing program.
 
RAW MATERIALS
 
    The Company uses a wide variety of raw materials in the manufacture of its
products and obtains such raw materials from a variety of suppliers. No single
supplier provides 10% or more of the Company's raw materials, nor do raw
materials from any one supplier generate 10% or more of the Company's
consolidated revenues. The Company has no long-term supply agreements relating
to raw materials.
 
WORKING CAPITAL
 
    The working capital requirements of the Company's divisions and subsidiaries
are financed primarily from operations.
 
PATENTS AND TRADEMARKS
 
    The Company owns a large number of patents, trademarks and copyrights
relating to its manufactured products, which have been secured over a period of
years. These patents, trademarks and copyrights have been of value in the growth
of the Company's business and may continue to be of value in the future.
However, the Company's business generally is not dependent upon the protection
of any patent, patent application or patent license agreement, or group thereof,
and would not be materially affected by expiration thereof.
 
RESEARCH AND DEVELOPMENT
 
    Expenditures on research and development activities amounted to $88.3
million, $91.0 million, and $94.5 million, in the years ended December 31, 1996,
1995 and 1994, respectively.
 
SEASONALITY; BACKLOG
 
    Oilfield Services' backlog seldom exceeds 30% of annual revenues at any
time. Sales backlog was $429 million and $359 million at December 31, 1996 and
1995, respectively.
 
    Backlog at Industrial Automation Systems comes primarily from manufacturing
systems businesses, and was $597 million and $581 million at December 31, 1996
and 1995, respectively.
 
    Although Oilfield Services' operations in any particular geographic area may
be affected by seasonal factors, the global nature of its operations tends to
reduce overall seasonal effects. The operations of Industrial Automation Systems
are not seasonal to any appreciable degree.
 
ENVIRONMENTAL MATTERS
 
    During the fiscal year ended December 31, 1996, the amounts incurred in
compliance with federal, state and local legislation pertaining to environmental
standards did not have a material effect upon the capital expenditures or
earnings of the Company.
 
EMPLOYEES
 
    As of December 31, 1996, the Company had approximately 14,000 full-time
employees, including approximately 8,900 in Oilfield Services and approximately
5,000 in Industrial Automation Systems.

</TABLE>
 
    YEAR ENDED DECEMBER 31, 1996 COMPARED TO 1995
 
    Total sales and service revenues and segment operating profit increased by
16% and 17%, respectively, and consolidated net earnings increased 26% compared
with prior year results.
 
    Sales and service revenues and operating profit for the Oilfield Services
segment increased by 11% and 10%, respectively, when compared to the prior
fiscal year. The fastest growth in Oilfield Services came from the Company's
seismic operations, where revenues grew by 15% in 1996. Western Geophysical, the
world's leading seismic services company, benefited from a number of highly
successful non-exclusive surveys, the expansion of its ocean-bottom cable
acquisition and processing technology, and its ongoing growth in the global land
market. Segment operating profits were impacted by continuing investments in the
E&P Services division and the PetroAlliance Services joint venture in the Former
Soviet Union ("FSU").
 
    Sales and service revenues and operating profit for the Industrial
Automation Systems segment increased by 23% and 33%, respectively, when compared
to the prior year results. Sales and operating profit of the Company's
Manufacturing Systems Group were improved over the prior year results, as
contracts with lower margins which affected 1995 results were completed and
replaced with contracts that yielded higher profit margins. Intermec, the
Company's automated data collection division, benefited from the success of new
product introductions and higher sales and service revenues under its five-year
purchasing agreement with the U.S. Government. Sales backlog for the Industrial
Automation Segment was $597 million at December 31, 1996, compared with $581
million at December 31, 1995.
 
    The Company sold its Material Handling Systems operations in November of
1996 and received cash proceeds of approximately $31 million. The activities of
the division were not considered a core business of the Company.
 
    YEAR ENDED DECEMBER 31, 1995 COMPARED TO 1994
 
    Total sales and service revenues and segment operating profit increased by
3% and 5%, respectively, and consolidated net earnings increased by 28% compared
with prior year results.
 
    Sales and service revenues and operating profit for the Oilfield Services
segment increased by 7% and 12%, respectively, when compared to the prior fiscal
year. Operating margins benefited from the improved profitability of seismic
services. The improvement in operating margins was partially offset by startup
costs

ITEM 7.  FINANCIAL REVIEW AND ANALYSIS (CONTINUED)
 
of the new E&P Services division, which is building its infrastructure in
response to developing customer projects in the U.S. and internationally.
 
    The assets of the seismic equipment manufacturing operations of the
Company's Oilfield Services segment were sold during the second quarter of 1995
for approximately $122 million cash. In June 1995, the Company formed a joint
venture to offer seismic, well-logging and integrated project services to local
and international oil companies operating in the FSU. The Company paid $21
million cash for 50% of the common equity of the venture, and has contributed
other assets in exchange for debt obligations and preferred shares of the
venture.
 
    Sales and service revenues and operating profit for the Industrial
Automation Systems segment decreased compared with prior year results. Backlog
for this segment was $581 million at December 31, 1995, compared with $415
million at December 31, 1994. The decrease in sales and service revenues from
the prior 12-month period resulted from several large programs with automobile
customers being completed and shipped near the end of 1994. The automated data
collection systems operations increased sales as markets for these products
continued to show growth.
 
    SUBSEQUENT EVENT
 
    On March 3, 1997, subsequent to fiscal year end 1996, the Company acquired
Norand Corporation ("Norand") in a transaction that is being accounted for as a
purchase. The preliminary purchase price of approximately $285 million
significantly exceeds the estimated net book value of the net assets acquired.
The allocation of the estimated purchase price to the net assets of Norand has
not been finalized. Norand's fiscal 1996 revenues were approximately $235
million. Norand's leadership in mobile computing, wireless data transmission,
pen-based systems, inventory tracking and route accounting activities directly
complement WAI's position in the industrial, governmental and distribution
markets for automated data collection.
 
    FOREIGN CURRENCY TRANSACTIONS
 
    The Company is subject to the effects of international currency fluctuations
due to the global nature of its operations. Currency fluctuations did not have a
significant impact on operations during fiscal years 1996, 1995 and 1994. It is
not possible to predict the Company's exposure to foreign currency fluctuations
beyond the near term because revenues generated from particular foreign
jurisdictions vary widely over time. The Company hedges transactions from time
to time, but the amount and volume of such transactions are not material.
 
    For fiscal year 1996, the Company derived approximately 46% of its revenues
and approximately 51% of its operating profits from non-U.S. operations.
However, at December 31, 1996, identifiable assets attributable to foreign
operations comprised 33% of total assets (of which the largest components were
attributable to European operations). Additionally, most of Oilfield Services'
identifiable assets used in generating foreign revenues are not stationary due
to the nature of its operations. Therefore, exposure of identifiable assets to
foreign currency fluctuations or expropriations is not significant.
 
    Oilfield Services derived approximately 70% of its revenues from non-U.S.
operations in fiscal year 1996. However, a significant amount of such revenues
is dollar-denominated. In addition, Oilfield Services has a policy of
structuring its contracts, whenever possible, so that revenues denominated in
foreign currencies do not exceed planned in-country costs of performing such
contracts. Cash in excess of operating requirements is maintained in the U.S.

ITEM 7.  FINANCIAL REVIEW AND ANALYSIS (CONTINUED)
 
    LIQUIDITY AND CAPITAL RESOURCES
 
    The Company had cash and cash equivalents of $165.8 million at December 31,
1996, compared with $116.7 million at December 31, 1995. The increase in capital
expenditures in 1996 to $303.6 million compared to $195.9 million in 1995 and
$170.1 million in 1994 is a result of ongoing business expansion in the Oilfield
Services segment. The Company expects that cash flow from operations, along with
available borrowing capacity, will provide the flexibility to meet strategic
objectives and the ability to meet working capital requirements. The Company
currently has unused credit facilities with a group of banks which permit the
Company to borrow up to $400 million. The purchase of Norand was funded using
short-term uncommitted borrowing lines and excess cash.
 
    On September 29, 1994, the Company sold an additional 6.9 million shares of
its common stock through an underwritten public offering. Proceeds to the
Company of $286.3 million were used to repay $200 million of notes issued in
connection with the repurchase of Dresser Industries' minority interest in the
Company's Oilfield Services operations, and a portion of the outstanding $130
million principal amount of the four-year term loan.
 
    The Company conducted a public offering of its debt securities during June,
1994 in the principal amount of $400 million. The proceeds were used to repay
previously outstanding credit facilities: a one-year $350 million bank loan, a
portion of the remaining bank loans and to pay certain expenses of the offering.
 
    Net interest expense for fiscal year 1996 was $38.0 million, compared with
$41.0 million and $56.2 million for fiscal years 1995 and 1994, respectively.
Decreased interest expense in 1996 and 1995 is primarily attributable to the
proceeds from the common stock offering mentioned above being used to reduce the
Company's debt.
 
    INFLATION
 
    In the opinion of management, inflation has not been a significant factor in
the markets in which the Company operates and has not had a significant impact
on the results of its operations.

WESTERN ATLAS INC.
MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL REPORTING
 
    The consolidated financial statements of Western Atlas Inc. and subsidiaries
and related financial information included in this Annual Report, have been
prepared by the Company, whose management is responsible for their integrity.
These statements, which necessarily reflect estimates and judgments, have been
prepared in conformity with generally accepted accounting principles.

assurance that assets are safeguarded and transactions are properly executed and
recorded. As part of this system, the Company has an internal audit staff to

    The Audit and Compliance Committee of the Board of Directors, which consists
solely of directors who are not employees of the Company, meets periodically
with management, the independent auditors and the Company's internal auditors to
review the scope of their activities and reports relating to internal controls
and financial reporting matters. The independent and internal auditors have full
and free access to the Audit and Compliance Committee and meet with the
Committee both with and without the presence of Company management.

Board of Directors and Shareholders
Western Atlas Inc.
Beverly Hills, California
 
    We have audited the accompanying consolidated balance sheets of Western
Atlas Inc. and subsidiaries as of December 31, 1996 and 1995, and the related
consolidated statements of income and cash flows for each of the years in the
three year period ended December 31, 1996. 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, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three year period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                               WESTERN ATLAS INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A:  SIGNIFICANT ACCOUNTING POLICIES
 
    GENERAL INFORMATION.  Western Atlas Inc. ("WAI" or the "Company") became an
independent public company on March 17, 1994 (the "Distribution Date") when its
common stock was distributed to stockholders of Litton Industries, Inc.
("Litton") in the form of a dividend (the "Distribution"). All of the WAI common
stock was distributed to Litton stockholders on the basis of one share of WAI
common stock for each share of Litton common stock held of record as of March
14, 1994.
 
    NATURE OF OPERATIONS.  WAI concentrates primarily on information technology
and is one of the world's leading oilfield information services and industrial
automation companies. The Company's Oilfield Services business segment provides
land and marine seismic, well-logging, and reservoir description and management
services for a worldwide client base. Oilfield Services' principal customers are
private sector and government-owned oil companies, and approximately 70% of its
revenues are generated by activities outside of the United States. The
Industrial Automation Systems segment of the Company provides integrated
manufacturing and automated data collection systems. Customers include the
automotive and off-road vehicle industries, retail and wholesale distribution
companies, manufacturing industries and government agencies.
 
    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 revenues 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. Investments in companies over which WAI has influence but
not a controlling interest are accounted for using the equity method. All
material intercompany transactions have been eliminated.
 
    EARNINGS PER SHARE.  Earnings per share computations are based on the
weighted-average number of common shares outstanding and common stock
equivalents with dilutive effects. The December 31, 1996, 1995 and 1994
computations were based on 54,450,546, 53,893,670 and 48,632,062
weighted-average shares, respectively.
 
    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.  Revenues are generally recognized when products are
shipped or as services are performed. Revenues and profits on long-term
contracts associated with the Company's Industrial Automation Systems operations
are recorded under the percentage-of-completion method of accounting. Any
anticipated losses on contracts are charged to operations as soon as they are
determinable. General and administrative costs are expensed as incurred.
 
    GEOPHYSICAL DATA.  Costs incurred in the creation of Company-owned
geophysical data, included (net of advances from customers) in geophysical data
and other assets, are capitalized and amortized over the anticipated sales which
the Company expects to realize from licensing of such data.
 
    RESEARCH AND DEVELOPMENT.  Research and development costs are charged to
expense as incurred. Worldwide expenditures on research and development
activities amounted to $88.3 million, $91.0 million and $94.5 million, in the
years ended December 31, 1996, 1995 and 1994, respectively.
 
                                      F-6
<PAGE>
NOTE A:  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
    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.
 
    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. For further
discussion of accounting policies for taxes see Note G.
 
    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 credit quality 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
spreading the trade credit risk.
 
    FOREIGN CURRENCIES.  The currency effects of translating the financial
statements of those non-U.S. entities of the Company which operate in local
currency environments are included in the "cumulative currency translation
adjustment" component of shareholders' investment. Currency transaction gains
and losses are included in the Consolidated Statements of Income and were not
material for any periods presented herein.
 
    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 plans with
respect to the operations to which the goodwill relates, particularly the
historical earnings and projected undiscounted cash flows of such operations.
 
    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.
 
NOTE B:  BUSINESS ACQUISITIONS, INVESTMENTS AND DISPOSITIONS
 
    ACQUISITIONS AND INVESTMENTS
 
    Subsequent to fiscal year end 1996, the Company entered into an agreement to
acquire Norand Corporation ("Norand") in a transaction that will be accounted
for as a purchase. The preliminary purchase price of approximately $285 million
substantially exceeds the estimated net book value of the net assets to be
acquired. The allocation of the estimated purchase price to the net assets of
Norand has not been finalized. The purchase of Norand will be funded using
short-term uncommitted borrowing lines and excess cash. Norand is involved in
mobile computing, wireless data transmission technology, pen-based systems,
inventory tracking and route accounting activities.
 
    The Company made several acquisitions and investments during 1995, including
50% of PetroAlliance Services, a joint venture offering seismic, well-logging
and integrated project services to local and international oil companies
operating in the former Soviet Union; 49% of Honsberg, a German machine tool
maker; and Cranfield Precision Engineering, a grinding technology company
located in the United Kingdom. These 1995 acquisitions and several smaller 1996
acquisitions are integral to the Company's goals, though not material in the
aggregate to the Company's consolidated financial statements.

NOTE B:  BUSINESS ACQUISITIONS, INVESTMENTS AND DISPOSITIONS (CONTINUED)
 
    In January 1994, the Company acquired from the Halliburton Company
substantially all of the assets (except real property) of its Geophysical
Services business for $204 million. The acquisition has been accounted for by
the purchase method.
 
    In January 1994, the Company acquired Dresser Industries, Inc.'s 29.5%
minority interest in Oilfield Services for a total purchase price of $558
million. The purchase price includes goodwill of approximately $277 million,
which is being amortized on a straight-line basis over a period of 40 years.
 
    DISPOSITIONS
 
    The Company sold its Material Handling Systems operations in November of
1996 and received cash proceeds of approximately $31 million. The activities of
the division were not considered a core business of the Company.
 
    The assets of the seismic equipment manufacturing operations of the
Company's Oilfield Services segment were sold during the second quarter of 1995
for approximately $122 million cash. As part of the sales agreement, the Company
entered into a commitment with the buyer to purchase $350 million of equipment.
The remaining equipment purchase commitment is approximately $191 million as of
December 31, 1996. The excess of the sales price over the net book value of the
assets sold was deferred and is being amortized as the Company purchases
products from the buyer.
 
NOTE C:  CASH AND CASH EQUIVALENTS, DEBT AND INTEREST
 
    Cash and cash equivalents amounted to $165.8 million and $116.7 million at

    The Company has a credit agreement which provides for revolving credit of up
to $400 million, all of which was available for the Company's general use as of
December 31, 1996. The purchase of Norand, as described in Note B, will be
funded in part by using a $200 million short-term uncommitted borrowing line
established in February of 1997.
 
    The Company is in compliance with its various debt and credit 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.
 
    Financial instruments on the Company's Consolidated Balance Sheet include
accounts receivable, accounts payable, and payrolls and related expenses, which
approximate their market values due to their short maturity. The $570 million of
notes payable and long-term obligations had an estimated fair market value of
$605 million as of December 31, 1996, based primarily on quoted market prices.
As discussed in Note I, the Company also has off-balance-sheet guarantees and
letter-of-credit agreements with face values totaling $185 million at December
31, 1996 relating principally to the guarantee of future performance on
contracts.

    STOCK OPTION INFORMATION
 
    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 12
years. The Company also has a Director Stock Option Plan which provides for the
grant of stock options to the Company's non-employee 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. The number of options so granted annually is
fixed by the plan. Such options become fully exercisable on the first
anniversary of their grant. Under these plans, there were 1,098,528 and
1,072,216 options exercisable as of December 31, 1996 and 1995, respectively,
and 1,461,066 available for grant as of December 31, 1996.

</TABLE>
 
    The weighted-average fair value of stock options granted during 1996 and
1995 were $12.8 million and $8.6 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
 
                                      F-12
<PAGE>
NOTE F:  SHAREHOLDERS' INVESTMENT (CONTINUED)
 
1996 and 1995, respectively: risk-free interest rates of 6.4% and 6.6%, expected
life of five years for both years; and expected volatility of 26% and 23%,
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 its eligible full-time
employees. Under the terms of the Plan, employees can choose each biannual
offering period 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 36,975 shares under the Plan in
1996, with approximately 20% of eligible employees participating. The
weighted-average fair value of purchase rights granted in 1996 was $471,800. 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 COST DISCLOSURE
 
    The Company accounts for its stock-based compensation plans in accordance
with Accounting Principles Board Opinion No. 25, under which no compensation
cost has been recognized for stock option awards or grants of stock purchase
rights. Had compensation cost for these plans been determined consistent with
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123), the Company's pro forma net income and earnings per
share for 1996 and 1995 would have been $122.8 million and $98.8 million,
respectively, and $2.26 and $1.83, respectively. 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 123 method of accounting has not been
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. 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 in August 2004.

million, in fiscal years ended December 31, 1996, 1995 and 1994, respectively.
 
NOTE H:  PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS
 
    PENSION BENEFITS
 
    The Company has retirement and pension plans which cover most of its
employees. Most of the Company's U.S. employees are covered by either a defined
contribution plan or by a contributory defined benefit plan.
 
    The Company contributes an amount based on the net earnings of Oilfield
Services in accordance with a defined contribution plan generally available to
employees of Oilfield Services. Under a contributory defined benefit plan
generally available to U.S. employees of Industrial Automation Systems and the
corporate office, the Company makes annual contributions to the extent such
contributions are actuarially determined.
 
    The Company also has defined contribution voluntary savings programs
generally available for U.S. employees, which are intended to qualify under
Section 401(k) of the Internal Revenue Code. These plans are designed to enhance
the retirement programs of participating employees. Under these plans, the
Company matches up to 50% of a certain portion of participants' contributions.
 
    The Company's non-U.S. subsidiaries also have retirement and savings plans
for long-term employees. The pension liabilities and their related costs are
computed in accordance with the laws of the individual nations and appropriate
actuarial practices.

1996 and 1995. The weighted-average discount rate used in determining the
actuarial present value of the projected benefit obligation was 7 1/2% at
December 31, 1996 and 1995. The rate of increase in future compensation levels
was 5% at December 31, 1996 and 1995.

</TABLE>
 
    The above table includes prepaid pension cost presented net of pension
liabilities for plans in which accumulated benefits exceed plan assets. As of
December 31, 1996 and 1995, these liabilities amounted to $18.4 million and
$10.9 million, respectively.
 
    Plan assets consist primarily of equity securities and U.S. Government
securities. The excess of plan assets over the projected benefit obligation at
August 1, 1986 (when the Company adopted SFAS No. 87) and subsequent
unrecognized gains and losses are fully amortized over the average remaining
service period of active employees expected to receive benefits under the plans,
generally 15 years.
 
    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% at December 31, 1996.
The rate of increase in future compensation used was approximately 5%, and the
rate of return on assets was 8 1/2% at December 31, 1996.
 
    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, 1996 was $77.3 million compared with net assets available for benefits of
$95.2 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,
1996 was $21.2 million, of which $15.3 million was attributable to retirees and
$5.9 million to other active plan participants. The accumulated benefit
obligation at December 31, 1995 was $20.6 million, of which $15.8 million was
attributable to retirees and $4.8 million was attributable to active plan
participants.
 
    Actuarial assumptions used to measure the accumulated benefit obligation
include a discount rate of 7 1/2% at December 31, 1996 and 1995. The assumed
health care cost trend rate for fiscal year 1996 was 12.7% and is projected to
decrease over 20 years to 6%, where it is expected to remain thereafter. 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-

NOTE H:  PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS (CONTINUED)
 
point increase in the assumed health care cost trend rate on the accumulated
benefit obligation results in an increase of approximately $1.5 million.
 
NOTE I:  LITIGATION, COMMITMENTS AND CONTINGENCIES
 
    The Company is currently, and is from time to time, subject to claims and
suits arising in the ordinary course of its business. In the opinion of the
Company's General Counsel, the ultimate resolution of currently pending
proceedings will not have a material adverse effect on the Company's financial
statements.
 
    The Company has issued or is a party to various guarantees and
letter-of-credit reimbursement agreements totaling $185 million at December 31,
1996, which relate principally to the guarantee of performance on contracts.
 
NOTE J:  RELATED PARTY TRANSACTIONS
 
    Included in accounts receivable are notes due from Company joint ventures of
$15.9 million and $45.1 million at December 31, 1996 and 1995, respectively.
Such amounts are partially collateralized by certain fixed assets of the joint
ventures and bear interest at 10% to 18%. Accounts payable includes $1.6 million
due to joint ventures at December 31, 1996.
 
    Included in geophysical data and other assets are amounts due from related
parties of $1.6 million and $2.1 million at December 31, 1996 and 1995,
respectively.
 
    During 1994, the Company was charged interest expense of $6.3 million on
advances from Litton.
 
NOTE K:  BUSINESS SEGMENT REPORTING
 
    The Company reports its operations in two business segments: the Oilfield
Services segment and the Industrial Automation Systems segment.
 
    The Oilfield Services segment performs seismic surveys, well-logging and
other services to the oil and gas industry. Such other services are primarily
for exploration and development of oilfields. A substantial amount of Oilfield
Services' business is service revenue generating. The Industrial Automation
Systems segment develops and installs integrated manufacturing systems and
automated data collection systems. Industrial Automation Systems' activities are
primarily product sales oriented. Export sales are not material.
 
    Corporate and other amounts include corporate operating costs, net interest
expense and currency transaction gains and losses (see Notes A and J). Assets
classified as corporate and other amounts consist primarily of cash and cash
equivalents and deferred taxes.

                                       RECITALS
                                       --------

    WHEREAS, Consultant is presently employed by Company as a Vice Chairman and
Chief Financial Officer; and

    WHEREAS, Consultant will retire from Company's employment on September
30,1996; and

    WHEREAS, Company believes that Consultant can contribute materially to
Company's future success in accomplishing certain projects relating to corporate
strategic development and financial issues; and

    WHEREAS, Company desires to engage Consultant as an independent contractor
for Company and Consultant desires to be so retained by Company.

    NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

    1.    SERVICES.

    (a)   Company hereby retains Consultant to render advice and assistance to
Company in connection with corporate strategic development and financial issues.
In this capacity, Consultant is responsible to, and shall act only upon
instructions of, Company through its designated Point of Contact identified
below.

    (b)   Unless otherwise directed in writing by the Chief Executive Officer
of Company, the designated Point of Contact shall be Alton J. Brann, Chief
Executive of the Company.

    (c)   Consultant shall make himself available for the rendering of
consulting services at times and places mutually agreed upon.  Consultant agrees
to use all reasonable efforts to make himself available to Company when so
requested and to devote the necessary time required for fulfillment of a
specific assignment; provided, however, that Consultant shall not be required to
provide more than fifty (50) days of service during a period of one calendar
year.

    (d)   Consultant shall serve Company at all times as an independent
contractor, not as an agent or employee of Company.  Consultant shall be subject
to Company's direction only as to specific areas of Company's interest with
respect to which Company desires the benefit of Consultant's advice and counsel.

    (e)   Without the prior consent of Company, Consultant shall not incur any
obligations on behalf of Company.


                                    1

<PAGE>

    (f)   Neither party hereto shall be liable to the other or in breach hereof
for any failure to perform its obligations hereunder if such failure is due to
causes reasonably beyond the defaulting party's control.

    2.    DUTIES.  Consultant shall devote all reasonable effort to perform
those assignments in the areas identified by Company's Point of Contact.  In all
instances, the Point of Contact for Company shall specifically advise Consultant
of those areas to be worked on by Consultant.

    3.    DURATION.  This Agreement shall be for an initial term of one (1)
year beginning on October 1, 1996, and may be renewable as mutually agreed upon
by both parties.  If Company desires to renew this Agreement, it shall so notify
Consultant within sixty (60) days of the end of the prior term.

    4.    COMPENSATION AND PAYMENT.

    (a)

         (i)  For services to be rendered, Consultant shall receive a Minimum
    Annual Fee of $150,000.00, payable in monthly installments of $12,500.00 per
    month at the end of each month or such other times as mutually agreed upon.
    This Minimum Annual Fee shall entitle Company to order and receive during 
    the initial term of this Agreement, and during any renewal period to which a
    Minimum Annual Fee is applicable, fifty (50) calendar days of service by 
    Consultant. Consultant shall be entitled to the Minimum Annual Fee whether 
    or not the Company orders fifty (50) calendar days of service.  In the event
    this Agreement is terminated for other than Consultant's death or breach 
    hereof, before fifty (50) calendar days of service have been ordered or 
    performed during any period to which an Annual Minimum Fee is applicable, 
    Consultant shall nevertheless be entitled to the Minimum Annual Fee and may
    bill Company for any amount of the Minimum Annual Fee not previously paid.  
    However, upon the death of Consultant, Company shall only be liable to pay 
    compensation at the rate of $3,000.00 per day for those days actually worked
    by Consultant, plus reimbursement for expenses incurred as specified in 
    subparagraphs 4(b) and (c) below; provided, however, that Consultant's 
    estate shall not be obligated to refund to Company any Minimum Annual Fee 
    monthly installments previously paid to Consultant.  For purposes of this 
    Agreement, Consultant is permitted to count as days of service one day for
    each assignment requiring travel in the continental United States, and up 
    to two days for each assignment requiring travel to a foreign destination,
    in addition to any other days of actual service performed by Consultant 
    under such an assignment.

         (ii)  For all services ordered by Company and performed by Consultant
    hereunder which exceed fifty (50) calendar days as set forth in paragraph
    4(a)(i) above for any period of one (1) year commencing on October 1 in 
    which the Minimum Annual Fee is applicable, Consultant shall receive as 
    compensation the sum of $3,000.00 per calendar day for


                                          2

<PAGE>

    each day or part thereof in which Consultant provides services and advice 
    to Company as ordered by Company Point of Contact.

         (iii)  To the extent this Agreement remains effective during any
    period in which a Minimum Annual Fee is not applicable, Consultant shall 
    receive as compensation the sum of $3,000.00 per calendar day for each day 
    or part thereof in which Consultant provides services and advice to Company 
    as ordered by Company Point of Contact.

    (b)   Company shall also reimburse Consultant for actual expenses incurred
in performing consulting services hereunder in accordance with Company's
standard policies and procedures relating to Company Officers.  During the term
of this Agreement and any renewal thereof, Company shall continue to provide
Consultant office space and secretarial services at the Company's offices.
During that period Company shall also continue to maintain the direct phone line
to Consultant's residence, maintain Consultant's residential security system and
provide a facsimile machine at Consultant's residence.  Expenses shall be
documented and substantiated with receipts, and Consultant shall submit invoices
for such expenses to Company Point of Contact for approval.

    (c)   Reimbursement of expenses shall be payable to Consultant within
fifteen (15) days following receipt by Company Point of Contact of an invoice
setting out expenses incurred.  With respect to each monthly installment of the
Minimum Annual Fee set forth in paragraph 4(a)(i) above, Consultant shall be
paid within seven (7) days of the end of each month.  For services performed by
Consultant which exceed fifty (50) days during any period of one (1) year
commencing on October 1 to which a Minimum Annual Fee is applicable, or for
services rendered during a period when no Minimum Annual Fee is applicable,
Consultant shall be paid within fifteen (15) days following receipt by the
Company Point of Contact of an invoice setting out the number of days worked by
calendar date in the previous month.  Unless otherwise requested by Consultant,
all payments shall be by check sent to the address of Consultant first set forth
at the beginning of this Agreement.

    5.    PRECEDENCE OF  COMPANY  ASSIGNMENTS.  Consultant agrees that he will
use his reasonable best efforts to give precedence to any assignment given
Consultant under this Agreement.


    6.    CONFIDENTIALITY--COVENANT NOT TO COMPETE.

    (a)   Because the work for which Consultant has been employed by Company
and the work for which he is being engaged, pursuant to this Agreement, has and
will include knowledge and information including, without limitation, customer,
supplier, sales and pricing information, research and development, business
plans, and organizational and personnel information of a private, confidential
or secret nature, belonging to or entrusted to Company, its affiliates and
subsidiaries, Consultant specifically covenants and agrees to hold such
knowledge and information in confidence, and shall not during or subsequent to
either his employment with Company or his retention as a Consultant to Company,
except as required in the conduct of Company's business or as otherwise first
authorized in


                                          3

<PAGE>

writing by Company, publish, disclose or make use of, or authorize anyone else
to publish, disclose or make use of, any such information or knowledge which in
any way relates to the business of Company.  All documents and written
information including, but not limited to, notes, sketches, manuals, blueprints,
notebooks, and records embodying Company business or industrial property, and
such documents and written information obtained by Consultant while employed by
Company, shall be the exclusive property of Company and, to the extent not
delivered to Company upon termination of employment with Company, shall be
delivered by Consultant to Company upon termination of this Agreement.

    (b)   Consultant agrees that during the term of this Agreement, Consultant
shall not engage in any occupation requiring Consultant's services for a
business which is competitive with the business conducted by Company or any of
its affiliates or subsidiaries, except with the prior written consent of
Company.

    (c)   During the period of this Agreement and for eighteen (18) months
following termination thereof, Consultant further agrees not to solicit,
interfere with, or endeavor to entice away, any employees or customers of
Company, its affiliates or subsidiaries, or to interfere with the business
relationship between Company, its affiliates, subsidiaries, and any customer,
supplier or other person, firm or corporation without the prior written consent
of Company.

    (d)   Consultant agrees that, in the event of any violation of the
restrictions referred to in this paragraph 6, Company shall be entitled to
preliminary and permanent injunctive relief, which right shall be cumulative and
in addition to any other rights or remedies to which Company may pursue in law
or equity, including the right to terminate Consultant's right to any further
compensation under this Agreement.  Consultant further agrees that, in the event
of any such violation by Consultant, Consultant shall forfeit the right to
receive any unpaid Minimum Annual Fee under this Agreement.  Company agrees that
Company shall not have the right to set off against any obligations of Company
to Consultant under any retirement benefit provided by Company any claims of
Company under this Agreement.

    7.    THIRD PARTY RELATIONSHIPS.  Consultant agrees that Company shall not
be obligated to third parties with whom Consultant shall contract without
Company's prior written consent.

    8.    COMPLIANCE WITH LAWS.  Consultant agrees in performance of this
Agreement to fully comply with all applicable foreign and U.S. federal, state
and local laws and regulations.

    9.    RELEASE.

    (a)   As a material inducement to Company to enter into this Agreement,
except as provided in subparagraph 9(d) below, Consultant hereby irrevocably and
unconditionally releases, acquits and forever discharges Company and all persons
acting by, through, under or in concert with Company (collectively "Releasees"),
or any of them, from any and all charges, complaints, claims, liabilities,
obligations, promises, agreements, controversies, damages, actions, causes of
actions, suits, rights, demands, costs, losses, debts and expenses (including
attorneys' fees and costs actually incurred) of any nature whatsoever, known or
unknown, suspected or


                                          4

<PAGE>

unsuspected, including, but not limited to, any claims for wages, employment
benefits, employment or reinstatement of employment, or damages arising out of
alleged violations of any contracts, express or implied, any covenant of good
faith and fair dealing, express or implied, any tort, any legal restrictions on
Company's right to terminate employees, or any federal, state, or other
governmental statute, regulation or ordinance, including, without limitation,
Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment
Act, the Older Workers Benefit Protection Act, the Worker Adjustment and
Retraining Notification Act, and the California Fair Employment and Housing Act,
which Consultant claims to have, own or hold, or which Consultant at any time
heretofore had, owned or held, or claimed to have, own or hold, against each or
any of the Releasees.

    (b)   Consultant expressly waives any and all rights under Section 1542 of
the Civil Code of the State of California, which provides as follows:

    "A general release does not extend to claims which the creditor does 
    not know or suspect to exist in his favor at the time of executing 
    the release, which if known by him must have materially affected his 
    settlement with the debtor."

Consultant expressly and completely waives and releases any right or benefit
which he has or may have under the Section 1542 of the Civil Code of the State
of California pertaining to the matters released herein.  In connection with
such waiver and relinquishment, Consultant acknowledges that he is aware that he
may hereafter discover claims presently unknown or unsuspected, or facts in
addition to, or different from, those which he now knows or believes to be true.

    (c)   Consultant hereby represents and acknowledges that he was allowed at
least twenty-one (21) days between his receipt of this Agreement and his
execution thereof, and that he was able to consider the terms thereof to his
full satisfaction and obtain legal advice, with particular attention to
references to the Age Discrimination in Employment Act and the Older Workers
Benefit Protection Act.  Consultant understands that, among other claims, he is
giving up all claims of age discrimination against Company which he might have
under the Age Discrimination in Employment Act or the Older Workers Benefit
Protection Act.

    (d)   This Agreement is not for the benefit of any third party which is not
a party to this Agreement and shall not be deemed to give any right or remedy to
any third party.  "Releasees" described above are considered parties to this
Agreement and are not third parties.  This Release does not extend to Company's
obligations under this Agreement, any Stock Option Contracts between Consultant
and Company, any rights of Consultant under Company's 1995 Incentive
Compensation Plan or Individual Performance Award with respect to the period
ending on September 30, 1996, any rights of Consultant arising as an employee of
Company or its predecessor through September 30, 1996, to salary or wages
accrued through September 30, 1996, any other employee benefits, e.g., health
insurance benefits accrued through September 30, 1996, and any rights of
Consultant to indemnification under the Delaware General Corporation Law, the
Restated Articles of Incorporation of the Company and indemnification provided
for employees under California law with respect to any acts or omissions of
Consultant as an  employee, officer or director of the Company on and prior to
