ITEM 1. BUSINESS.
 
  Nalco Chemical Company was incorporated in 1928 in Delaware and has its
principal executive offices at One Nalco Center, Naperville, Illinois 60563.
Its telephone number is 708-305-1000, and beginning August 3, 1996 the
telephone number will be 630-305-1000. As used in this report, "Company" and
"Nalco" refer to Nalco Chemical Company and its consolidated subsidiaries.
 
  Nalco is engaged in the manufacture and sale of highly specialized Service
Chemicals. Specified financial information by geographic area is shown in Note
2 of the Notes to Consolidated Financial Statements in the Company's 1995
Annual Report to Shareholders and is incorporated herein by reference.
 
  Nalco's business includes the production and sale of chemicals, technology,
services, and systems (monitoring and surveillance) used in water treatment,
pollution control, energy conservation, steelmaking, papermaking, mining and
mineral processing, electricity generation, other industrial processes, and
commercial building utility systems. Service Chemicals are developed and
formulated to meet specific customer needs. In general, they are part of value
added programs designed to help customers maintain a high level of operating
performance and efficiency in their facilities, improve the quality of
customers' end products, or help customers meet environmental discharge limits
in a cost-effective way. Nalco products are used for purposes such as: control
of scale, corrosion, foam and fouling in cooling systems, boilers, and other
equipment; clarification of water; improved combustion; separation of liquids
and solids; control of dust; lubrication and corrosion protection in rolling,
drawing and forming of metals; improved production of pulp and qualities of
paper; recovery of minerals; and specialized process applications in a variety
of industries. The quality and on-site availability of technical expertise
provided through highly qualified Nalco personnel are very important
considerations to customers since the effective use of the Company's products
requires a substantial amount of problem solving, monitoring, and technical
assistance on the part of Nalco employees.
 
  Service Chemicals are usually marketed through Nalco's own organization
because of the high degree of technical service required. The worldwide field
sales force is trained in the application and use of Nalco Service Chemicals,
and is supported by a marketing staff of specialists in the technology and use
of various Nalco Service Chemicals.
 
  Competitive conditions vary for Nalco depending on the industries served and
the products involved. Management believes the Company is one of the most
important worldwide suppliers of water treatment products and service chemical
programs, based on estimated sales of comparable products for industrial
customers on the process side (e.g., the manufacturing process, which a plant
uses to produce its end product) and the water treatment side (e.g., boilers
for power generation or cooling systems for process temperature control). The
Company sells its water treatment products and service chemical programs in
more than 100 countries, and is the largest or second largest supplier of
those products in most of the countries it does business. All aspects of this
business are considered to be very competitive, and companies providing
similar products or programs range in size from very large multinational
companies to small local manufacturers. The number of competitors varies by
product application and ranges from a few large companies to hundreds of small
local companies. The Company's principal method of competition is based on
quality service, product performance and technology through safe, practical
applied science.
 
  On February 2, 1996, Nalco announced its plan to dispose of its
superabsorbent chemicals business. The results of this business are now
reported as discontinued operations. The operations and the net assets of this
business are held for sale. Nalco does not anticipate a loss from the
operations from this business during the phase out period nor a loss on the
ultimate disposition of this business. This business generated annual revenue
of approximately $96 million for the year 1995.
 
  Effective October 1995, Nalco purchased an additional 25 percent of the
common shares of Nalco Chemical India, Ltd., and now owns 65 percent of this
company. In November 1995, Nalco purchased the pulp and paper chemical
business of Texo Corporation.
 
                                       1

ITEM 1. BUSINESS. (CONT'D)
 
  There were no other significant changes in the markets served or in the
methods of distribution since the beginning of 1995.
 
  Although no single Service Chemicals product represents a material portion
of the business, historically, new product and new market developments have
been designed to increase market penetration and to maintain sales and
earnings growth.
 
OTHER MATTERS
 
  Primarily as a result of the formation of the Nalco/Exxon joint venture, the
Company adopted a worldwide consolidation plan in 1994 for manufacturing and
support operations. The production volume reduction caused by redundancies
associated with the joint venture formation required the Company to downsize,
close, and consolidate operations. The Company's South Chicago plant was
closed, and several European and Latin American manufacturing and support
operations have been or will also be closed or downsized. In addition, certain
support functions will be regionalized on a pan-European basis in order to
more efficiently serve customers. All of these activities are in process, and
should be largely completed by the end of 1996.
 
  The principal raw materials used by Nalco ordinarily are available in
adequate quantities from several sources of supply in the United States and in
foreign countries. Purchases of chemicals are made in the ordinary course of
business and in accordance with the requirements of production.
 
  Inventories of Service Chemicals are maintained in Nalco-owned facilities
and in warehouses situated throughout the United States and in countries in
which subsidiaries operate. Shipments to customers may be made from either
manufacturing plants or warehouse stocks.
 
  Nalco owns or is licensed under a large number of patents relating to a
number of products and processes. Nalco's rights under such patents and
licenses are of significant importance in the operation of the business, but
no single patent or license is believed to be material with respect to its
business. Over 700 patents existed at the end of 1995 with remaining durations
ranging from less than one year to 17 years with an average duration of about
10 years.
 
  Nalco's business is considered nonseasonal. Large dollar amounts of backlogs
are unusual since chemicals are normally shipped within a few days of the
receipt of orders. The dollar amount of the normal backlog of orders is not
considered to be significant in relation to the total annual dollar volume of
sales of Nalco.
 
  The Company does not depend upon either a single customer, or very few
customers, for a material part of the business.
 
  Nalco's laboratories are involved in research and development of chemical
products and in providing technical support, including chemical analyses of
water and process samples. Research and development expenses of continuing
operations amounted to $39.8 million in 1995, compared to $45.7 million in
1994, and $49.7 million in 1993.
 
  There were approximately 6,100 persons employed full time by Nalco at the
end of 1995.
 
  Compliance with Federal, State, and local regulations relating to the
discharge of materials into the environment, or otherwise relating to the
protection of the environment, has not had a material effect upon the capital
expenditures, earnings, or competitive position of Nalco. There are no
material capital expenditures for environmental control facilities anticipated
during 1996. Compliance with increasingly stringent regulations should not
have a material effect upon earnings but may strengthen the competitive
position of Nalco because of available capital and technical resources.
 
  Although inflation is not a significant factor domestically, the Company
adjusts selling prices to maintain profit margins wherever possible.
Investments are made in modern plants and equipment that will increase
productivity and thereby minimize the effect of rising costs. In addition, the
last-in, first-out (LIFO) valuation
 
                                       2

ITEM 1. BUSINESS. (CONT'D)
 
method is used for some of the Company's inventories, so that changing
material costs are recognized in reported income and pricing decisions. The
impact of inflation in foreign exchange movements at foreign subsidiaries is
managed by minimizing assets exposed to currency movements and by increasing
sales prices to parallel increases in local inflation rates. The Company
emphasizes working capital management, frequent dividend remittance, timely
settlement of intercompany account balances, foreign currency borrowings, and
selected hedging. In most hyperinflationary economies, the rate of local
currency devaluation is related to and approximately equal to the local
inflation rate. Therefore, Nalco attempts to increase its local selling prices
to help offset the impact of devaluation on exposed assets and the impact of
increases in local content costs.

  Our audits of the consolidated financial statements referred to in our
report dated February 2, 1996 appearing on page 13 of the 1995 Annual Report

Form 10-K) also included an audit of the Financial Statement Schedule listed
in Item 14(a) of this Form 10-K. In our opinion, this Financial Statement
Schedule presents fairly, in all material respects, the information set forth
therein when read in conjunction with the related consolidated financial
statements.

REPORT OF INDEPENDENT ACCOUNTANTS

Price Waterhouse LLP

To the Board of Directors                             [LOGO OF PW APPEARS HERE] 
and Shareholders of                                             
Nalco Chemical Company

In our opinion, the accompanying statements of consolidated financial condition
and the related consolidated statements of earnings, of cash flows and of common
shareholders' equity present fairly, in all material respects, the financial
position of Nalco Chemical Company and its subsidiaries at December 31, 1995 and
1994, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

As discussed in the notes to the financial statements, the Company changed its
method of accounting for postretirement benefits other than pensions in 1993.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Sales*
(millions of dollars)

[GRAPH APPEARS HERE}

*Based on continuing operations. Amounts for 1991-1994 include the Company's
 petroleum chemical operations.

1995 vs 1994 . On February 2, 1996, the Company announced its plan to dispose of
its superabsorbent chemicals business. Accordingly, its results are now reported
as discontinued operations. The operations and the net assets of this business
are held for sale. Since the Company's entrance into this business in 1987, the
market for this product has changed significantly, and is now characterized by
price sensitivity and little opportunity for product or service differentiation.
This business no longer fits the Company's strategy of delivering value to its
customers through on-site expertise and innovative products and services. The
Company does not anticipate a loss from operations from the superabsorbent
chemicals business during the phase out period nor a loss on the ultimate
disposition of the business, and therefore has not recognized any loss provision
related to the disposal. Earnings from the discontinued operation were $18
million in 1995, down $6 million from 1994. (See Note 3).

Effective September 1, 1994, Nalco and Exxon Chemical Company (Exxon), a
division of Exxon Corporation, formed Nalco/Exxon Energy Chemicals, L.P.
(Nalco/Exxon), a joint venture partnership to provide specialty chemical
products and services to the petroleum and chemicals industries worldwide.
Nalco's investment in the joint venture is accounted for by the equity method.
(See Note 11).

At the time of formation of Nalco/Exxon, Nalco transferred the business and
sales volume of its U.S. Petroleum Chemicals Division and certain petroleum
chemical product lines of its international operations to the joint venture.
While this formation did not change Nalco's net assets or results of operations,
several historical captions in the consolidated financial statements were
affected. Because 1994 results have not been reclassified to exclude petroleum
chemical operations, the following unaudited statement of consolidated earnings
for the year ended December 31, 1994 is presented. It reflects results of
operations on a comparable basis with 1995; that is, Nalco petroleum chemical
operations are excluded for the first eight months of 1994 and recognized as if
they were accounted for by the equity method.

Depreciation
(millions of dollars)

[GRAPH APPEARS HERE]

The following discussion of results of operations compares 1995 to the
reclassified 1994 results presented above.

Sales by the Water and Waste Treatment Division were up 2 percent, with solid
improvements reported by the UNISOLV and WATERGY Groups. A more modest increase
was reported by the Basic Industry Group. The Process Chemicals Division posted
a 13 percent sales improvement as double-digit gains were posted by all three
groups in the Division. Sales by the Europe Division were up 10 percent. The
weaker dollar compared to a year ago accounted for part of this increase, but
double-digit gains in local currencies were reported by subsidiaries in Italy
and Spain, as well as the Division's Pan European Paper business. The Latin
America Division turned in a 15 percent sales improvement, as double-digit gains
were reported by subsidiary companies in Argentina, Brazil, and Chile. Slightly
more than two-thirds of the increase for the Division was attributable to
Nalcomex (Mexico), a former affiliate, which became a wholly owned subsidiary in
the fourth quarter 1994. Sales by the Pacific Division rose 17 percent, as
double-digit gains were reported by all but two of the subsidiary companies in
the Division.

Cost of products sold was 43.7 percent of sales for 1995, compared with 43.5
percent of sales for 1994. Increased raw material costs, partly offset by higher
selling prices, accounted for slightly lower gross margins reported by
operations in North America in 1995. However, gross margins of the International
Divisions were slightly higher than last year on a combined basis.

Operating expenses in 1995 rose $35 million, or 8 percent over 1994, excluding
the $68 million charge in 1994 for formation and consolidation expenses
discussed below. Selling and service expenses accounted for this increase,
primarily to support growth in Latin America, the Pacific, and the worldwide
paper market. The increase was also partly attributable to the weaker dollar
used to translate expenses of most international subsidiaries, mainly those in
Europe.

Worldwide, research expenses were comparable to 1994, as increased expenses in
Europe and the Pacific were offset by lower expenses in the United States and
Latin America. Higher European and Pacific research costs reflect a full year of
operations in 1995 for new facilities opened during 1994. The reduction in
research expenses in the United States was mainly attributable to lower employee
benefit costs. As a percent to sales, research expenses were 3.3 percent in 1995
compared to 3.6 percent in 1994.

Administrative expenses for 1995 were down slightly from 1994 as a result of
lower provisions for incentive plans and employee benefit costs.

Primarily as a result of the formation of the Nalco/Exxon joint venture, the
Company adopted a worldwide consolidation plan for manufacturing and support
operations during 1994. As a result of this plan, the Company recorded a pretax
provision for formation and consolidation expenses of $68 million ($54 million
after tax, or 70 cents per share on a fully diluted basis). (See Note 4).

Interest and other income for 1995 was down $9 million from 1994. This was
primarily attributable to a $5 million gain on the sale of the Company's
automotive paint spray booth business in 1994. Also contributing to the decrease
was a drop in interest income as a result of lower invested cash balances, and
lower realized exchange and unrealized translation gains reported by the
Company's subsidiary in Brazil.

Interest expense totaled $16 million in 1995, a decrease of $5 million from
1994, which was also mainly attributable to the Company's Brazilian subsidiary.
This change, along with the change in realized exchange and unrealized
translation gains discussed above, was the result of a monetary control program
instituted by the Brazilian government in mid-1994.

Nalco's equity in earnings of Nalco/Exxon was $17 million, a $3 million decline
from the $20 million combined earnings reported by Nalco petroleum chemical
operations from January to August 1994 and the Company's equity in the joint
venture's earnings. This decrease reflects the weak petroleum market in the
United States, as well as start-up and consolidation expenses for the joint
venture.

The effective tax rate for 1995 was 36.4 percent, comparable to the 1994
effective tax rate based on the reclassified results for 1994 presented above,
excluding the formation and consolidation expense of $68 million and related net
tax benefit of $14 million.

Earnings from continuing operations as a percent to sales was 11.2 percent in
1995. Based on the reclassified results above and excluding the net formation
and consolidation expense, earnings from continuing operations as a percent to
sales was 11.5 percent in 1994.

Market Value of Nalco Common Share at Year-End Closing Price
(in dollars)

[GRAPH APPEARS HERE]
 
The Company makes limited use of derivative financial instruments such as
interest rate swaps and foreign exchange contracts. Interest rate swaps are used
to reduce the potential impact of increases in interest rates on floating rate
long-term debt, while foreign exchange contracts are used to minimize exposure
and reduce risk from exchange rate fluctuations. The Company does not hold or
issue financial instruments for trading purposes. (See Note 17).

The Company is involved in environmental clean-up activities in connection with
former waste disposal sites and plant locations and litigation in the normal
course of business. (See Note 19). This involvement has not had, nor is it
expected to have, a material effect on the Company's earnings or financial
position.

In 1995, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 121 (SFAS 121), "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires
companies to review long-lived assets, including identifiable intangibles and
goodwill, for indicators of impairment. The Company is required to adopt SFAS
121 effective January 1, 1996. Management believes that the effect of this
adoption will not have any material impact on the results of operations or the
financial position of the Company.

In 1995, the Financial Accounting Standards Board also issued Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation," which requires companies to account for employee stock-based
compensation plans using a fair value based method of accounting. However, SFAS
123 allows companies to continue to apply the intrinsic value based method
prescribed under Accounting Principles Board Opinion No. 25 (APB 25),
"Accounting for Stock Issued to Employees," provided certain pro forma
disclosures are made with respect to a fair value method. The Company is
required to adopt SFAS 123 effective January 1, 1996, and although it has not
yet determined the complete impact of the pronouncement, it has decided it will
continue to apply the intrinsic value method under APB 25.

1994 vs. 1993

As previously discussed, the formation of the Nalco/Exxon joint venture in
September 1994 did not change Nalco's net assets or results of operations, but
several historical captions in the consolidated financial statements were
affected. Because 1993 results have not been reclassified to exclude petroleum
chemical operations, the following unaudited statement of consolidated earnings
for the year ended December 31, 1993 is presented. It reflects results of
operations on a comparable basis with 1994; that is, Nalco petroleum chemical
operations are excluded for the last four months of 1993 and recognized as if
they were accounted for by the equity method.

The following discussion of results of operations compares 1994 to the
reclassified 1993 results presented above.

Sales by the three units comprising U.S. Operations rose 2 percent in 1994, as
seven of the eleven marketing groups posted higher sales. Sales by International
Operations were up 3 percent. Sales by European subsidiaries were down 3
percent, primarily as a result of lower sales to the Middle East by our
subsidiary company in Italy. In Latin America, sales increased 19 percent over
1993 with gains reported by all operations in the region, most notably
Argentina, the Caribbean, and Venezuela, which reported double-digit advances.
About one-fifth of the increase in Latin America was attributable to sales by
Nalcomex (Mexico), a former affiliate, which became a wholly owned subsidiary in
the fourth quarter 1994. In the Pacific, double-digit sales gains by all
subsidiaries in the region, except Australia and Taiwan, contributed to a 10
percent improvement over 1993.

Cost of products sold was 43.6 percent of sales for 1994, compared with 42.8
percent of sales for 1993. Slightly lower selling prices, combined with
increased raw material costs and manufacturing expenses, accounted for lower
gross margins reported by U.S. Operations in 1994. Gross margins of our foreign
subsidiaries, primarily in Europe, were also slightly lower than in 1993.

Operating expenses in 1994 rose $17 million, or 3 percent over 1993, excluding
the $68 million charge in 1994 for formation and consolidation expenses. Selling
and service expenses were up $17 million, or 4 percent over last year, which was
primarily attributable to growth in our International Operations, principally in
the Pacific and Latin America.

Worldwide, research expenses increased 1 percent over 1993, which was also
mainly to support growth overseas. The European Business and Technical Center in
the Netherlands and a technical center in Singapore were opened during 1994 to
better serve our customers in Europe and the Pacific. Research expenses were 3.7
percent of sales in 1994 and 1993.

Administrative expenses for 1994 were down slightly from 1993 as lower
provisions for incentive plans were partly offset by higher salaries and
benefits.

As previously disclosed, the Company recorded a pretax provision for formation
and consolidation expenses of $68 million ($54 million after tax, or 70 cents
per share on a fully diluted basis) in 1994. (See Note 4).

Interest and other income for 1994 was $17 million, a $2 million improvement
over 1993. This increase was primarily the result of a $5 million gain on the
sale of the Company's automotive paint spray booth business. This business had
generated annual revenues of approximately $10 million. Interest income,
however, was $1 million lower than in 1993. Results for 1993 also included a $2
million gain on the sale of an investment in a mutual insurance company.

Interest expense totaled $22 million in 1994, a decrease of $6 million from
1993, which was mainly attributable to lower average borrowing levels and a
monetary control program instituted by the Brazilian government that resulted in
lower interest expense reported by our subsidiary company in Brazil.

Nalco's equity in earnings of Nalco/Exxon for the last four months of 1994 was
$7 million, compared to $8 million in 1993 for the Nalco petroleum chemical
operations. Start-up costs incurred by Nalco/Exxon in 1994, coupled with
unusually good results for the Nalco petroleum chemical operations in the fourth
quarter 1993, account for this variation.

Excluding the formation and consolidation expense of $68 million and related net
tax benefit of $14 million, the effective tax rate was 38.2 percent. This
compares to the actual 1993 effective tax rate of 38.9 percent, and a 38.3
percent effective tax rate based on the reclassified results for 1993 presented
above.

Earnings from continuing operations as a percent to sales was 5.9 percent in
1994. Excluding the net formation and consolidation expense, earnings as a
percent to sales would have been 10.2 percent. Based on the reclassified results
above, earnings from continuing operations as a percent to sales was 10.6
percent in 1993.

Earnings from the Company's discontinued superabsorbent chemicals operation were
$24 million in both 1994 and 1993.

During the first quarter 1993, the Company recorded an extraordinary loss of $11
million as a result of the early repayment of long-term debt. (See Note 15).

Effective January 1, 1993, the Company implemented, on the immediate recognition
basis, Statement of Financial Accounting Standards No. 106 (SFAS 106),
"Employers' Accounting for Postretirement Benefits Other Than Pensions." The
adoption of SFAS 106 resulted in a non-recurring charge to 1993 earnings of $57
million, net of $33 million of income tax benefits. (See Note 6).

Also effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes," and
Statement of Financial Accounting Standards No. 112 (SFAS 112), "Employers'
Accounting for Postemployment Benefits." Adoption of these pronouncements did
not have a material effect on the Company's earnings or financial position.

FINANCIAL CONDITION

Total assets increased $88 million, or 7 percent during 1995.

Accounts receivable were $14 million, or 7 percent higher than at the end of
1994. This reflects higher worldwide sales levels in the fourth quarter 1995,
most notably in North America and the Pacific.

Inventories increased $8 million, or 9 percent over year-ago levels. This was
primarily attributable to operations in North America and the Pacific to support
the sales growth in those regions.

Prepaid expenses, taxes, and other current assets were down $7 million from
1994, which was mainly due to a decrease in deferred tax assets related to the
Company's accrual for formation and consolidation expenses.

Investment in and advances to partnership rose $17 million during 1995, which
primarily reflected Nalco's $17 million of equity in the earnings of
Nalco/Exxon.

The $47 million net carrying amount of assets of discontinued operations
consists primarily of buildings and manufacturing equipment of the
superabsorbent chemicals business.

To support asset growth, liabilities increased $52 million, or 7 percent, which
consisted primarily of a net increase in short-term and long-term debt of
approximately $50 million. Of this increase, $45 million was raised through the
issuance of commercial paper.

Shareholders' equity increased $36 million, or 7 percent during 1995, primarily
because net earnings of $154 million exceeded the sum of dividends (totaling $78
million) plus common stock repurchases of 1.3 million shares at a cost of $42
million. Treasury stock transactions for stock option, benefit, and other plans
totaled $12 million, and the stronger U.S. dollar in relation to the Mexican
peso and most Pacific currencies compared to the end of 1994 resulted in a $9
million increase in foreign currency translation adjustments.

Nalco's return on average shareholders' equity was 24.1 percent in 1995,
slightly higher than the 22.9 percent in 1994 based on earnings from continuing
operations and before the net $54 million charge for formation and consolidation
expenses in 1994.

CASH FLOWS

One of Nalco's most significant financial strengths is its ability to
consistently generate strong cash flow from operations. Net cash provided by
operating activities was $213 million in 1995, which was generated primarily
from net earnings before noncash charges for depreciation and amortization.

Capital Additions
(millions of dollars)

[GRAPH APPEARS HERE]
 
Significant cash flow requirements in 1995 included capital investments of $127
million, dividends of $78 million, and $42 million for the reacquisition of
common stock.

In 1994, cash from operations of $249 million was slightly lower than the 1993
total of $256 million.

Over two-thirds of the 1995 capital investments of $127 million was attributable
to investments in the United States, which included $26 million for PORTA-
FEED(R) units, $17 million for field equipment, and $13 million for
transportation equipment. The Company plans to continue to invest in internal
growth in 1996 and it is expected that capital investment will exceed $100
million, but be less than the 1995 level.

Other significant investing activities in 1995 included the acquisition of an
additional 25 percent interest of Nalco Chemical India, Ltd., a former
affiliated company, for approximately $10 million net of cash acquired, and the
purchase of the pulp and paper chemical business of Texo Corporation for $14
million. Additional cash investments in Nalco/Exxon totaled $8 million in 1995.

Investing activities in 1994 totaled $164 million, which included $126 million
for investments in property, plant, and equipment. Over 60 percent of the
capital spending in 1994 was for investments in the United States and included
$19 million for PORTA-FEED units, $18 million for field equipment, and $14
million for transportation equipment. The most significant investment overseas
was $18 million to complete the construction of the Nalco Europe Business and
Technical Center in the Netherlands, which was opened in mid-1994. Investing
activities in 1994 also included the purchase of the remaining 60 percent
interest of Nalcomex (Mexico), a former affiliated company, for approximately
$18 million, and cash investments in Nalco/Exxon of $26 million. Net cash
provided by investing activities during 1993 was negligible. Investments in
property, plant, and equipment of $118 million were offset by the cash proceeds
received from the liquidation of marketable securities and the sale of Adco
Products, Inc. Domestic investments accounted for about two-thirds of the
capital spending for 1993, including $18 million for PORTA-FEED units, $17
million for field equipment, and $18 million for transportation equipment. The
largest foreign expenditure for 1993 was $11 million for the construction of the
European Business and Technical Center.

Net financing activities of $61 million in 1995 included dividends paid on
common stock of $67 million or $.99 per share. Since the Company's founding in
1928, it has paid 270 consecutive quarterly dividends, and expects to continue
its policy of paying regular cash dividends. The Company continued its stock
repurchase program in 1995 by reacquiring 1.3 million shares of common stock at
a cost of $42 million. In 1994, the Company reacquired 1.8 million shares of
common stock at a cost of $61 million, and 1.7 million shares were repurchased
for $59 million in 1993. Management believes that the stock repurchase program
represents a sound economic investment for Nalco's shareholders. Other financing
transactions in 1995 consisted primarily of additional short-term borrowings of
$46 million.

Among the most significant financing activities in 1994 and 1993 were payments
for cash dividends and the repurchase of common stock. Financing activities in
1993 also included the repayment of $160 million of commercial paper
borrowings.

Management expects that internal growth in existing businesses will be financed
principally from internally generated funds. For general purposes and to support
the ESOP loans and the issuance of commercial paper, Nalco also has a $260
million Revolving Credit Agreement with ten banks. The credit arrangements were
unused at December 31, 1995. (See Note 14). In addition, most foreign
subsidiaries have established short-term borrowing facilities in local currency
and use them as the need arises. Net debt (short-term and long-term borrowings
less cash and cash equivalents) totaled $278 million, $222 million, and $189
million at December 31, 1995, 1994, and 1993, respectively.

The Company has $66 million of debt which matures in February 1996. A commitment
to refinance $38 million of this debt has been received from the lenders, and it
is expected that the remaining $28 million will be repaid with proceeds from the
issuance of commercial paper.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION POLICY . Nalco's consolidated financial statements include the
accounts of the parent company and its majority-owned subsidiaries. All
intercompany balances and transactions are eliminated. In 1993, the fiscal year
end of the consolidated foreign subsidiaries was changed from November 30 to
December 31. As a result of the change, the Company recorded the results of its
foreign operations for the month of December 1992 directly to retained earnings.
Investments in partnerships and affiliated companies are reported on the equity
method.

Certain amounts in the prior years' financial statements have been reclassified
to conform to the current year presentation.

USE OF ESTIMATES . 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 during the
reporting period. Actual results could differ from those estimates.

CONCENTRATION OF CREDIT RISK . Credit risk represents the accounting loss that
would be recognized at the reporting date if counterparties failed completely to
perform as contracted. Management believes the likelihood of incurring material
losses due to concentration of credit risk is remote. The principal financial
instruments subject to credit risk are as follows:

   Cash and cash equivalents, short-term marketable securities . Nalco has a
   formal policy of placing these instruments in investment grade companies or
   financial institutions and limiting the size of an investment with any single
   entity.

   Receivables . A large number of customers in diverse industries and
   geographies, as well as the practice of establishing reasonable credit lines,
   limits credit risk. The allowances for doubtful accounts are adequate to
   cover potential credit risk losses.

   Foreign exchange contracts and derivatives . The Company has formal policies
   which establish credit limits and investment grade credit criteria of "A" or
   better for all counterparties.

CASH AND CASH EQUIVALENTS . Cash and cash equivalents include all cash balances
and highly liquid investments with original maturities of three months or less.

DERIVATIVES . Gains and losses on hedges of existing assets or liabilities are
included in the carrying amounts of those assets or liabilities and are
ultimately recognized in income as part of those carrying amounts. Gains and
losses related to qualifying hedges of firm commitments also are deferred and
are recognized in income or as adjustments of carrying amounts when the hedged
transaction occurs.

FOREIGN CURRENCY TRANSLATION . The local currency has been designated as the
functional currency in financial statements of companies which account for
approximately 87 percent of total foreign subsidiary net assets at the end of
1995. These financial statements are translated at current and average exchange
rates, with any resulting translation adjustments included in the currency
translation adjustment account in shareholders' equity. The remaining
subsidiaries operate in countries with highly inflationary environments and
their statements are translated using a combination of current, average, and
historical exchange rates, with the resulting translation impact included in
results of operations. Transactions executed in different currencies resulting
in exchange adjustments are included in results of operations. The impact of
foreign currency exchange transactions, included in interest and other income in
1995, 1994, and 1993, was not significant.

INVENTORY VALUATION . Inventories are valued at the lower of cost or market.
Approximately 39 percent of the inventories at the end of 1995 are valued using
the last-in, first-out (LIFO) method. The remaining inventories are valued using
the average cost or first-in, first-out (FIFO) method. If the FIFO method of
accounting had been used for all inventories, reported inventory amounts would
have been $25 million higher at both December 31, 1995 and 1994.

GOODWILL . Goodwill consists of costs in excess of the fair value of tangible
net assets of acquired companies and is generally amortized over 40 years using
the straight-line method. The Company annually evaluates whether the projected
earnings and undiscounted cash flows of each of the acquired companies is
sufficient to recover the carrying value of the net investment, including
goodwill, in order to determine if an impairment has occurred. Management is
currently of the opinion that no such impairment exists.

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 (SFAS 121), "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
SFAS 121 requires companies to review long-lived assets, including identifiable
intangibles and goodwill, for indicators of impairment. If those indicators
suggest an impairment issue exists, future cash flows from the investment must
be estimated for comparison to the carrying value. An impairment loss would be
recorded if the carrying value exceeded the total future cash flows.

The Company is required to adopt SFAS 121 effective January 1, 1996. Management
believes that the effect of this adoption will not have any material impact on
the results of operations or the financial position of the Company.

INCOME TAXES . Income taxes are recognized during the year in which transactions
enter into the determination of financial statement income, with deferred income
taxes being provided for the tax effect of temporary differences between the
carrying amount of assets and liabilities and their tax bases.

Deferred income taxes are provided on the undistributed earnings of foreign
subsidiaries and affiliated companies except to the extent such earnings are
considered to be permanently reinvested in the subsidiary or affiliate. Where it
is contemplated that earnings will be remitted, credit for foreign taxes already
paid generally will offset applicable U.S. income taxes. In cases where foreign
tax credits will not offset U.S. income taxes, appropriate provisions are
included in the Consolidated Statements of Earnings. Repatriation of
                                     
                                      24

permanently reinvested earnings would not materially increase the Company's tax
liabilities.

RETIREMENT PLANS - The cost of retirement plans is computed on the basis of
accepted actuarial methods (using the projected unit credit method for the
principal plan) and includes current service costs, amortization of increases in
prior service costs over the expected future service of active participants as
of the date such costs are first recognized, and amortization of the initial
unrecognized net pension asset or liability on a straight-line basis over 18
years.

The costs of health and life insurance postretirement benefits are accrued as
earned. Annual expense represents a combination of interest and service cost
provisions.  Most postretirement benefits are not funded.

EMPLOYEE STOCK OWNERSHIP PLAN (ESOP) - ESOP contribution expense is based upon
non-level debt payments made by the ESOP to meet the plan funding requirements.
An adjustment to expense is made when the computed amount is less than 80
percent of the cumulative expense that would be recognized under the "shares
allocated" method.

EARNINGS PER SHARE - Primary earnings per common share is computed by dividing
net earnings (after deducting preferred stock dividends, net of income taxes) by
the weighted average number of shares and share equivalents outstanding during
the year.  Fully diluted earnings per share is based upon the weighted average
number of common shares and share equivalents, plus the weighted average number
of common shares resulting from the assumed conversion of the Series B ESOP
Convertible Preferred Stock (preferred stock).  Earnings for purposes of
computing fully diluted earnings per share are reduced for additional ESOP debt
service expense resulting from the assumed replacement of preferred stock
dividends with common stock dividends, net of related tax benefits.


NOTE 2: BUSINESS SEGMENT AND GEOGRAPHIC AREA DATA

Nalco is engaged in the worldwide manufacture and sale of highly specialized
Service Chemical programs.  This includes production and service related to the
sale and application of chemicals and technology used in water treatment,
pollution control, energy conservation, oil production and refining,
steelmaking, papermaking, mining, and other industrial processes.

Within Nalco, sales between geographic areas are made at prevailing market
prices to customers minus an amount intended to compensate the sister Nalco
company for providing quality customer service.

Operating earnings represent sales less cost of products sold and operating
expenses.  In computing operating earnings by geographic area, none of the
following items is considered: general corporate expenses, interest income or
expense, equity in earnings of partnerships and affiliated companies, or income
taxes.

Identifiable assets are those directly associated with operations of the
geographic area.  Corporate assets consist mainly of cash and cash equivalents;
marketable securities; investments in unconsolidated partnership, affiliates,
and leveraged leases; and capital assets used for corporate purposes.  Corporate
assets for 1995 also include the net assets of discontinued operations, which
are classified as North American identifiable assets for years 1994 and 1993.

Sales and operating earnings for 1994 and 1993 include results for the Company's
U.S. Petroleum Chemicals Division and certain petroleum chemical product lines
of its international operations which were transferred to Nalco/Exxon effective
September 1, 1994.  Sales included were approximately $137 million in 1994 and
$243 million in 1993.  (See Note 11).

The decrease in operating earnings in 1994 was mainly attributable to the pretax
provision of $68 million for formation and consolidation expenses.  (See Note
4).  Of that amount, approximately $34 million was included in European
operations.


NOTE 3: DISCONTINUED OPERATIONS

On February 2, 1996, the Company announced its plan to discontinue the
operations of its superabsorbent chemicals business.  The operations and the net
assets of this business are held for sale.  The Company does not anticipate a
loss from operations from the superabsorbent chemicals business during the phase
out period nor a loss on the ultimate disposition of the business, and therefore
has not recognized any loss provision related to the disposal.  Operating
profits generated during the phase out period and any gain on the disposition
would be recognized in the Company's results when realized.  The amounts the
Company will ultimately realize could differ from the estimates used in arriving
at the assumption that no loss will arise on the disposal of the discontinued
operations.

The net carrying amount of assets of discontinued operations, which is
segregated under Other Assets on the 1995

                                      25
<PAGE>
 
Statement of Consolidated Financial Condition, consists primarily of accounts
receivable, inventory, buildings, and manufacturing equipment.  Sales from the
discontinued operation, which are excluded from consolidated sales, amounted to
$96 million in 1995, $99 million in 1994, and $98 million in 1993.  
Discontinued operations results totaled $18 million in 1995, and $24 million in
both 1994 and 1993. Results included the pretax operating earnings of the
discontinued operation, less allocated income taxes of $11 million in 1995, and
$15 million in both 1994 and 1993. The effective income tax rate for
discontinued operations differs from the federal statutory rate primarily
because of state income taxes, net of federal tax benefit.


NOTE 4: FORMATION AND CONSOLIDATION EXPENSES

The Company adopted a worldwide consolidation plan for manufacturing and support
operations during 1994, primarily as a result of the formation of Nalco/Exxon
discussed in Note 11.  The production volume reduction caused by redundancies
associated with the joint venture formation required the Company to downsize,
close, and consolidate operations.  The Company's South Chicago plant was
closed, and several European and Latin American manufacturing and support
operations have been or will be closed or downsized.  In addition, certain
support functions are being regionalized on a pan-European basis in order to
more efficiently serve customers.  Certain redundant assets that were not
contributed to the joint venture have been written down to net realizable value,
and assets associated with other programs have been or will be written off.  All
of these activities are in process, and should be largely completed by the end
of 1996.

As a result of these plans, the Company recorded a pretax provision of $68
million ($54 million after tax, or 70 cents per share on a fully diluted basis)
in 1994.  Included in this provision is the cost of termination benefits for the
elimination of over 400 positions, primarily in the United States and Europe,
including manufacturing and support personnel, which will require approximately
$27 million in cash.  Costs associated with facility closings and the
disposition of assets that are no longer productive total approximately $24
million, including $21 million for non-cash asset write-offs and $3 million in
cash payments associated with asset disposals.  The remaining $17 million of the
pretax costs represents anticipated cash payments for post-closure plant
environmental remediation, legal and consulting fees, and other exit costs.  
Cash expenditures charged against the provision to date have been funded through
operating cash flows, and the Company anticipates that future cash expenditures
will be similarly funded.  A tax benefit of $14 million, net of tax costs
associated with the contribution of assets to various joint venture entities,
was included in the Company's 1994 income tax provision related to the formation
and consolidation expenses.

Charges against the provision for formation and consolidation expenses totaled
$25 million in 1994 and $20 million in 1995, and over 300 employees had been
terminated as of December 31, 1995.  The following table sets forth the details
of activity in the accrual for formation and consolidation expenses for 1995:

NOTE 5: PENSION PLANS

The Company has several noncontributory defined benefit pension plans covering
most employees in the United States and those with eight foreign subsidiaries.
The principal domestic plan represents approximately 70 percent of the projected
benefit obligation (PBO) and 82 percent of the total market value of assets.
This plan provides benefits that are based on years of service and the
employee's highest paid 48 months during the last 120 months before termination
of employment.  Approximately 95 percent of the assets in the plan at December
31, 1995 was invested in stocks, bonds, and insurance contracts, and the
remaining assets were invested in professionally managed real estate trusts and
partnerships.  No contributions have been made since 1984 due to the present
funded position of the plan, and none are anticipated in 1996. Five of the eight
foreign pension plans are unfunded, generally because amounts contributed are
not deductible for tax purposes.

Employees in the United States whose pension benefits exceed ERISA limitations
are covered by a supplementary non-qualified, unfunded pension plan which is
being provided for by charges to earnings sufficient to meet the projected
benefit obligation.  The accruals for the cost of this plan are based on
substantially the same actuarial methods and economic assumptions as those used
for the principal plan.

Net pension expense for all defined benefit plans included in operating results
was comprised of:

</TABLE>

In accordance with Statement of Financial Accounting Standards No. 87 (SFAS 87),
"Employers' Accounting for Pensions," the Company has recorded a minimum pension
liability for certain plans, representing the excess of the ABO over plan assets
and accrued pension costs. A corresponding amount was recognized as an
intangible asset, except to the extent that these additional liabilities
exceeded related unrecognized prior service cost and net transition obligation,
in which case the increase in liabilities was charged directly to shareholders'
equity. The excess minimum pension liability resulted in after-tax charges to
shareholders' equity of $6 million, net of income taxes of $4 million, each year
for 1995 and 1994.

NOTE 6: POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

Nalco has defined benefit postretirement plans that provide medical, dental, and
life insurance benefits for substantially all United States retirees and
eligible dependents. Nalco retains the right to change or terminate these
benefits. Effective January 1, 1993, the Company implemented, on the immediate
recognition basis, Statement of Financial Accounting Standards No. 106 (SFAS
106), "Employers' Accounting for Postretirement Benefits Other than Pensions."
This statement requires that the cost of these benefits be recognized in the
financial statements during an employee's active working career with the
Company. Nalco's previous practice was to expense these costs as incurred.

The adoption of SFAS 106 resulted in a noncash charge of $57 million, net of $33
million of income tax benefits in 1993.

Net postretirement benefit expense for all defined benefit plans included in
operating results was comprised of:

</TABLE>

The health care cost trend rate will decrease 0.5 percent per year to an
ultimate rate of 5.0 percent. A one-percentage-point increase in the assumed
health care cost trend rate would have increased the 1995 postretirement benefit
expense by approximately $1 million and would have increased the 1995
accumulated postretirement benefit obligation by $7 million.

NOTE 7: EMPLOYEE STOCK OWNERSHIP PLAN (ESOP)

Nalco's ESOP gives most United States employees an additional opportunity to
share in the ownership of the Company's stock. Preferred shares are allocated to
eligible employees based on a percentage of pretax earnings.

Selected information about the ESOP is as follows:

NOTE 8: STOCK OPTION AND PERFORMANCE PLANS

Nalco's 1990 Stock Option Plan for key management employees authorized the
granting of stock options for the purchase of up to 6,000,000 shares of Nalco
common stock. Nalco's 1982 Stock Option Plan authorized the granting of either
incentive stock options or non-qualified options for the purchase of up to
6,000,000 shares of Nalco's common stock. No additional grants will be made
under the 1982 plan. The option price under both plans cannot be less than the
fair market value on the date of grant. Options granted since 1989 become
exercisable ratably over the three years following the grant date, and will
expire 10 years after the date granted. Options granted prior to 1989 have a
term of 10 years, and were exercisable upon grant. Options may be exercised in
whole or in part for cash, shares of common stock, or a combination thereof.

The changes in shares under option to employees are summarized as follows:

The 1990 Stock Option Plan for Non-Employee Directors authorizes the granting of
stock options to outside directors for the purchase of up to 500,000 common
shares. The option price under the plan cannot be less than the fair market
value on the date of the grant and options expire 10 years from the grant date.
A total of 36,000 options was granted under the directors' plan during 1995 at
an option price of $33.81 per share, a total of 36,000 options was granted under
the directors' plan during 1994 at an option price of $32.69 per share, and a
total of 36,000 options was granted under the directors' plan during 1993 at an
option price of $32.94 per share. These options were exercisable upon grant, and
2,000 shares were exercised during 1995, at an average price per share of
$33.81.

A Performance Share Plan for designated officers and other key executives was
approved by shareholders in 1992. It provides for the annual assignment of
performance shares which are contingent upon future earnings growth of the
Company. Performance awards shall be paid half in cash and half in the Company's
common stock, except that any payments made after 1,000,000 shares have been
issued shall be made only in cash and only with respect to contingent
performance shares already assigned. The cash portion of an award shall be paid
after determination of the award; however, the right to receive common shares
shall not vest to a participant until three years after the end of a performance
period.

No significant charge to earnings was made for all stock-related plans in 1995
or 1994.  In 1993, $4 million was charged to earnings for stock-related plans.

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation."  SFAS 123 requires companies to account for employee stock-based
compensation plans using a fair value based method of accounting.  However, SFAS
123 allows companies to continue to apply the intrinsic value based method
prescribed under Accounting Principles Board Opinion No. 25 (APB 25),
"Accounting for Stock Issued to Employees," provided certain pro forma
disclosures are made with respect to a fair value method.  The Company is
required to adopt SFAS 123 effective January 1, 1996.  The Company has not yet
determined the impact of this pronouncement, but has decided it will continue to
apply the intrinsic value method under APB 25.


NOTE 9: INCOME TAXES

Effective January 1, 1993, Nalco adopted Statement of Financial Accounting
Standards No. 109 (SFAS 109), "Accounting for Income Taxes."  The cumulative
effect of the change in the method of accounting for income taxes as of the
beginning of 1993 was not material.

The sources of earnings from continuing operations before income taxes were as
follows:

The significant decrease in foreign source earnings in 1994 is primarily
attributable to formation and consolidation expenses. (See Note 4).

The components of income tax provisions attributable to earnings from continuing
operations are summarized as follows:

Current foreign taxes listed above include taxes withheld by foreign governments
on distributions from subsidiaries and affiliates (principally dividends and
service fees).  Current foreign taxes in 1994 also include $11.3 million of
taxes on partnership formation.

Nalco made income tax payments of $77 million, $92 million, and $87 million
during 1995, 1994, and 1993, respectively.

The effective income tax rate varies from the federal statutory rate because of
the factors indicated below:

</TABLE>

Deferred tax assets are to be reduced by a valuation allowance if it is "more
likely than not" that some portion or all of the deferred tax assets will not be
realized.  No valuation allowance was necessary as a result of management's
evaluation of the likelihood that all of the deferred tax assets will be
realized.


NOTE 10: ACQUISITIONS

Effective October 1995, the Company purchased an additional 25 percent of the
common shares of Nalco Chemical India, Ltd. (Nalco India) from ICI India, Ltd.
for approximately $11 million.  The purchase price exceeded the fair value of
the net assets acquired by $9 million.  Nalco already owned 40 percent of the
common shares of Nalco India and had been accounting for earnings on the equity
basis. The operations of this former affiliated company were consolidated
effective October 1995.

In November 1995, the Company purchased the pulp and paper chemical business of
Texo Corporation for $14 million.

                                      29
<PAGE>
 

The purchase price exceeded the fair value of the net assets acquired by $13
million.

In October 1994, the Company purchased the remaining 60 percent of the common
shares of Nalcomex, S.A. de C.V. in Mexico for $18 million. The purchase price
exceeded the fair value of the net assets acquired by $9 million. Nalco already
owned 40 percent of the common shares of Nalcomex and had been accounting for
earnings on the equity basis. The operations of this former affiliated company
were consolidated effective October 1994.

The pro forma impact as if these acquisitions had occurred at the beginning of
the respective years is not significant.

NOTE 11: INVESTMENT IN AND ADVANCES TO PARTNERSHIP

The Company's investment in partnership consists of its 60 percent interest in
Nalco/Exxon, a joint venture partnership which was formed on September 1, 1994.
In connection with the formation of Nalco/Exxon in 1994, the Company invested
cash of $26 million and transferred inventories of $13 million; property, plant,
and equipment of $70 million; and employee related liabilities of $20 million.
The assets transferred consisted of Nalco's U.S. Petroleum Chemicals Division
and certain petroleum chemical product lines of its international operations,
while Exxon transferred similar assets to the joint venture. Additional assets
contributed by the Company to the joint venture in 1995 consisted primarily of
cash of $8 million.

All significant management decisions of the joint venture require agreement by
both the Company and Exxon. In addition, certain provisions of the joint venture
agreement provide Exxon with an option to cause Nalco/Exxon to redeem a portion
of the Company's interest in Nalco/Exxon such that subsequent to such
redemption, the Company and Exxon shall share equally in the results of the
joint venture. As a result of the Company not exercising control over
Nalco/Exxon, its investment in the joint venture is accounted for by the equity
method.

The following table summarizes the Company's equity in earnings of Nalco/Exxon
and distributions from the partnership for the year 1995 and its initial four
months of operations in 1994:

</TABLE>

The Company's investment in Nalco/Exxon at December 31, 1995 included $3.2
million for the net excess of the Company's investment over its equity in the
joint venture's net assets which is being amortized to equity earnings over the
life of the related assets. In addition, the Company received an 8 percent and
10 percent earnings preference in 1995 and 1994, respectively, which has been
included in equity earnings.

Condensed balance sheet information for the Nalco/Exxon joint venture at
December 31, 1995 and 1994 was as follows:

</TABLE>

The Company entered into a four year agreement with Nalco/Exxon on September 1,
1994 to provide certain administrative services to the partnership. Fees earned
by the Company in 1995 and 1994 were $16 million and $5 million, respectively.

In the normal course of business, the Company supplies Nalco/Exxon with certain
products, and purchases certain products from Nalco/Exxon. These transactions
are generally at cost and were not significant in 1995 or 1994.

NOTE 12: FINANCE SUBSIDIARIES

Nalco has four finance subsidiaries, one wholly-owned and three 80%-owned, which
were established to increase the return on financial assets. These subsidiaries
are the lessor of a diversified portfolio of leveraged leases involving
creditworthy lessees. Amounts related to the finance subsidiaries which are
included in the Statements of Consolidated Financial Condition and Earnings are
as follows:

</TABLE>

Investments in leased property represent future rentals and residuals, net of
nonrecourse debt. The leased assets are financed primarily by nonrecourse loans
which are secured by the lessees' rental obligations and the leased property,
but ownership of the property is retained by the finance subsidiaries. Such
loans amounted to approximately $51 million at December 31, 1995 and $56 million
at December 31, 1994. Income from leveraged lease transactions is reported on
the financing method, which requires income recognition over the life of the
lease at a level rate of return on the positive net investment.

NOTE 13: PROPERTY, PLANT, AND EQUIPMENT

Property, plant, and equipment (including major improvements) are recorded at
cost. Depreciation of buildings and equipment is calculated over their estimated
useful lives generally using the straight-line method. The estimated

                                      30
<PAGE>
 

useful lives of the major classes of depreciable assets are as follows:
buildings 15 to 40 years; equipment 3 to 15 years.

Property, plant, and equipment consists of the following:

NOTE 14: SHORT-TERM DEBT

Short-term debt consists of the following:

- - ----------------------------------------============
</TABLE>

The weighted average interest rate on short-term debt was 7.8% and 12.2% at
December 31, 1995 and 1994, respectively. The rate for 1994 excludes the effect
of short-term borrowings in the highly inflationary economy of Brazil.

For general purposes and to support the ESOP loans and the issuance of
commercial paper, Nalco has a $260 million Revolving Credit Agreement with ten
banks. This agreement is structured as a five-year revolving credit. Borrowings
under the credit agreement would be at rates which, at Nalco's option, vary with
the prime rate, CD rate, LIBOR, or money market rates. The credit line carries a
facility fee of .10 percent. The credit arrangements were unused at December 31,
1995 and 1994.

NOTE 15: LONG-TERM DEBT

Long-term debt consists of the following:

</TABLE>

In 1989, the ESOP borrowed $200 million to purchase preferred stock from the
Company. Nalco borrowed $66 million which was subsequently loaned to the ESOP,
and guaranteed the balance of $134 million. Borrowings related to the ESOP are
reflected as long-term debt with a corresponding reduction of shareholders'
equity (unearned ESOP compensation). The ESOP is repaying the loans and interest
over a projected 20-year period ending December 31, 2008 using Company
contributions and dividends from preferred stock. As the principal amount of the
borrowings is repaid, the debt and the unearned ESOP compensation are being
reduced. $88 million of borrowings are variable rate notes which are presently
remarketed on a monthly basis with a final maturity on December 31, 2008. Any
notes which cannot be successfully remarketed will be purchased by the Company
or one of its subsidiaries. The Company entered into an interest rate swap
agreement which effectively converted the $88 million of variable rate notes
into fixed-rate debt of 7.3 percent. The notional value of the swap agreement
decreased to $78 million in February 1995, and will decrease to $59 million, $51
million, and $43 million in February 1996, 1997, and 1998, respectively. The
remaining borrowings are 8.1 percent fixed-rate loans with a final maturity in
the year 2000.

The $78 million in other long-term debt includes $47 million owed by two foreign
subsidiaries at variable interest rates. The balance was borrowed by the parent
company and various foreign subsidiaries.

During 1993, the Company repaid $160 million of commercial paper borrowings
which had been classified as long-term debt. The early retirement of this debt
resulted in an extraordinary loss of $11 million net of tax benefits of $6
million.

Interest paid by Nalco was $15 million, $20 million, and $33 million in 1995,
1994, and 1993, respectively.

The following table presents the projected annual maturities of long-term debt
for the next five years after 1995:

<TABLE>

1998                                12.0
1999                                12.0
2000                                10.2
- - ----------------------------------------
</TABLE>

The amounts above include approximately $74 million in maturities related to the
ESOP loans. The Company has a commitment from its lenders to refinance $38
million of a $66 million ESOP loan which was to mature in February 1996. The new
loan has a final maturity of December 31, 2008. Accordingly, the Company has
classified this portion of the loan as long-term.

NOTE 16: SHAREHOLDERS' EQUITY

Information on preferred and common shares is summarized in the following table:

There were 13,163,155 shares and 12,387,441 shares held in treasury at December
31, 1995 and 1994, respectively.

In 1994, Nalco's Board of Directors authorized the repurchase of up to 2 million
shares of the Company's common stock. During 1995, the Company repurchased
approximately 1.3 million of those shares.

The Company issued 415,800 shares of preferred stock to the ESOP in 1989 for
$481.00 per share, the preference price upon liquidation. This preferred stock
ranks senior to Series A Junior Participating Stock and common stock as to the
payment of dividends and the distribution of assets on liquidation, dissolution
and winding up of Nalco. Dividends on each share of preferred stock are
cumulative and will be paid quarterly at the rate of 8 percent or $38.48 per
annum. Full conversion of preferred shares occurs upon a holder's retirement or
separation of service from the Company, and effective in 1999 participants in
the ESOP may partially convert their stock upon reaching age 55. The conversion
ratio and number of votes per share of preferred stock are subject to adjustment
under certain conditions. The preferred stock entitles a participant to 20 votes
per share, voting together with the holders of common stock and initially was
convertible into 20 shares of common stock. The shares of preferred stock are
redeemable by Nalco at $495.43 per share, and at prices declining annually to
$481.00 per share on or after May 15, 1997. Also, the shares of preferred stock
may be required to be redeemed by Nalco under certain circumstances. During
1995, 4,801 preferred shares were converted to 96,212 common shares of Nalco
stock. During 1994 and 1993, 3,582 and 3,226 preferred shares were converted to
72,212 and 61,566 common shares, respectively. Approximately 8,000,000 common
shares have been reserved for the conversion of preferred stock.

In 1986, the Board of Directors declared a dividend distribution of one
Preferred Share Purchase Right (Right) for each outstanding share of common
stock. The Rights, as amended in 1989, are not exercisable or transferrable
apart from the common stock until a person or group has acquired, or makes a
tender offer for 15 percent or more of the common stock. If Nalco is acquired in
a merger or other business combination transaction, each Right other than that
held by the acquiring party will entitle the holder to receive, upon exercise at
a price of $50, common stock of either Nalco or the acquiring company having a
value equal to two times that price. The Rights are redeemable at $.025 each at
any time before a 15 percent or greater position has been acquired, and expire
on August 31, 1996.

NOTE 17: FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

Nalco has limited involvement with derivative financial instruments and does not
trade them. The Company does use derivatives to fix the cost of issuing debt and
to manage well defined interest rate and foreign exchange exposures.

  Notional Amounts and Credit Exposures of Derivatives -

  The notional amounts of derivatives summarized below do not represent amounts
  exchanged by the parties and, thus, are not a measure of the exposure of the
  Company through its use of derivatives. The amounts exchanged are calculated
  on the basis of the notional amounts and the other terms of the derivatives,
  which relate primarily to interest rates and foreign exchange rates.

  The Company is exposed to credit-related losses in the event of nonperformance
  by counterparties to financial instruments, but it does not expect any
  counterparties to fail to meet their obligations given their high credit
  ratings.

  Interest Rate Risk Management -

  Interest rate swap agreements are used to reduce the potential impact of
  increases in interest rates on floating rate long-term debt. As of December
  31, 1995 and 1994, the Company was a counterparty to six interest rate swaps:

  1.  One interest rate swap with a notional value of $78 million at December
      31, 1995 and $88 million at December 31, 1994 fixes interest payments on a
      corresponding amount of floating rate ESOP notes at 7.3 percent until
      February 1999. The notional amount decreases to $59 million, $51 million,
      and $43 million in 1996, 1997, and 1998, respectively. The average
      interest rate received on this interest rate swap was 4.9 percent and 3.5
      percent in 1995 and 1994, respectively.

  2.  Three interest rate swaps entered into in 1991 were designed to fix
      interest rate payments at 8.5 percent on $160 million of floating rate
      debt used to acquire affiliated companies in that year. In 1993, with cash
      from the sale of other subsidiaries, Nalco elected to repay the $160
      million of debt, and therefore entered into two interest rate swaps with
      an aggregate notional value of $160 million which offset the three 1991
      interest rate swaps. Nalco receives 4.6 percent on these two swaps in
      exchange for paying a floating rate of interest equal to the floating rate
      received on the 1991 swaps. All five of these agreements mature in March
      1996. The average interest rate received on the 1991 interest rate swaps
      and the average rate paid on the 1993 interest rate swaps was 6.0 percent
      in 1995 and 4.4 percent in 1994.

  Foreign Exchange Risk Management -

  The Company enters into various types of foreign exchange contracts in
  managing its intercompany foreign exchange risk, including currency swaps and
  forward exchange contracts.

  The Company's currency swap agreements were designed to hedge foreign currency
  intercompany loans that have maturities up to ten years. Gains and losses
  related to these swaps are offset with gains and losses on the underlying
  foreign currency loans. Forward exchange contracts are used to hedge various
  intercompany transactions with

                                      32
<PAGE>
 

  foreign subsidiaries and usually have maturities of six months, but
  occasionally may mature in one year.

  The Company had foreign exchange contracts with a notional value of $115
  million and $160 million at December 31, 1995 and 1994, respectively.

  Deferred realized and unrealized gains and losses from firm foreign currency
  commitments, based on dealer-quoted prices, are included in the Statements of
  Consolidated Financial Condition as either miscellaneous other assets or
  accounts payable. They are recognized in earnings as part of the underlying
  transaction when it is recognized. There was no net deferred realized and
  unrealized gain or loss at December 31, 1995. The net deferred realized and
  unrealized loss was $0.5 million at December 31, 1994.

NOTE 18: FAIR VALUE OF FINANCIAL INSTRUMENTS

The following table presents the carrying amounts and fair values of the
Company's financial instruments at December 31, 1995 and 1994:

- - -----------------------------------------------------------------
</TABLE>

The following methods and assumptions were used to estimate the fair values of
financial instruments:

  Cash and cash equivalents - The carrying amount approximates fair value
  because of the short-term maturities of such instruments.

  Short-term debt - The carrying amount approximates fair value because of the
  short-term maturities of such instruments.

  Long-term debt - The carrying amount of term borrowings at variable interest
  rates approximates fair value. The fair value of the Company's fixed-rate ESOP
  borrowings was estimated using discounted cash flow analyses, based on the
  Company's current borrowing rates for similar types of borrowing arrangements.

  Derivatives - The fair value of derivatives, including currency swaps, foreign
  currency forward exchange contracts, and interest rate swaps was estimated
  based on current settlement prices, quoted market prices of comparable
  contracts, and pricing models or formulas using current assumptions.

NOTE 19: CONTINGENCIES AND LITIGATION

Nalco has been named as a potentially responsible party (PRP) by the
Environmental Protection Agency (EPA) or state enforcement agencies at 15 waste
sites where some financial contribution is or may be required.

These agencies have also identified many other parties who may be responsible
for clean-up costs at the waste disposal sites. Nalco's financial contribution
to remediate these sites is expected to be minor. There has been no significant
financial impact on Nalco up to the present, nor is it anticipated that there
will be in the future, as a result of these matters. Nalco has and will continue
to make provisions for these costs if the Company's liability becomes probable
and when costs can be reasonably estimated. As of December 31, 1995, the Company
had undiscounted reserves of approximately $1 million for the maximum amount of
known environmental clean-up costs. The Company's 1995 expenditures relating to
environmental compliance and clean-up activities were not significant. These
environmental reserves represent management's current estimate of its
proportional clean-up costs and are based upon negotiation and agreement with
enforcement agencies, its previous experience with respect to clean-up
activities, a detailed review by the Company of known conditions, and
information about other PRPs. They are not reduced by any possible recoveries
from insurance companies or other PRPs not specifically identified. Although
management cannot determine whether or not a material effect on future
operations is reasonably likely to occur, given the evolving nature of
environmental regulations, it believes that the recorded reserve levels are
appropriate estimates of the potential liability. Although settlement will
require future cash outlays, it is not expected that such outlays will
materially impact the Company's liquidity position.

In 1994, Nalco provided $9 million for estimated post-closure costs at 15
locations for site remediation as part of the formation and consolidation plan
described in Note 4. These facilities, which were used for manufacturing and/or
warehousing, are in the process of being prepared for disposal or alternative
uses. In addition, the Company retained some liability for potential future
environmental costs at active locations contributed to Nalco/Exxon. In 1995, the
Company charged approximately $1 million against this provision, and reevaluated
its estimates of the remaining post-closure costs for the aforementioned
facilities. As a result, the provision was reduced by $2 million.

It is the Company's policy to accrue for estimated post-closure and site
remediation costs when the decision has been made by management to close a
facility.

In the ordinary course of its business, Nalco is also a party to a number of
lawsuits and is subject to various claims, the outcome of which, in the opinion
of management, should not have a material effect on the consolidated financial
position of Nalco.

                       Report of Independent Accountants
                       ---------------------------------

                                                     

March 21, 1996

To the Employee Benefit Plan
 Administration Committee of
 Nalco Chemical Company


In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
benefits of the Nalco Chemical Company Profit Sharing, Investment and Pay
Deferral Plan at December 31, 1995 and 1994, and the changes in net assets
available for benefits for the years then ended, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the plan's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The additional information included in the
supplementary schedules is presented for purposes of additional analysis and is
not a required part of the basic financial statements but is additional
information required by ERISA. Such information has been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

requirement exists before an employee is eligible to participate in the Plan.
Pursuant to section 6 of the Plan document, profit sharing contributions are at
the discretion of the Company. The Company has not contributed to the Plan since
January 1, 1990. The Plan also accepts transfers of Company common stock and
cash from the Employee Stock Ownership Plan for retirees.

Beginning in 1993, the Plan expanded to include seven investment alternatives:
the Nalco Stock Fund, the U.S. Government Money Market Fund, the Stable Capital
Fund, the Bond Index Fund, the Balanced Fund, the Growth and Income Fund, and
the Equity Index Fund. In 1995, an international equity fund was added, the
EuroPacific Fund. A participant who has attained the age of 50 can transfer once
per calendar year a minimum of 10% of his balance from the Nalco Stock Fund to
any of the other funds in the Plan. The maximum allowable transfer is determined
by the Employee Benefit Plan Administration Committee (EBPAC). Participants
electing to make tax-deferred contributions through cash or salary deductions
have the option of investing these contributions in a combination of any of the
funds. Participants can transfer assets acquired with their individual funds at
their discretion.

A participant can also make contributions which are not tax-deferred through
payroll deductions or a lump-sum investment. All participant contributions vest
immediately, and participants are entitled to their entire account balance upon
retirement, termination, disability, or death as a lump-sum payment (or in semi-
annual stock installments for shares in the Nalco Stock Fund).

Effective June 1, 1993, participants are allowed to borrow from the Plan,
provided the amount does not exceed the lesser of one-half the vested Plan
balance of the participant, or $50,000. The length of the loan is decided by the
employee, subject to certain governmental restrictions, and the interest charged
is determined by EBPAC and communicated to the participants in writing.

At December 31, 1995, employees participating in the Plan had invested in the
available funds as follows (some have investments in more than one fund):

The Company believes that the Plan will continue without interruption, but
reserves the right to terminate the Plan at any time. In the event of
termination of the Plan, the Nalco Chemical Company Profit Sharing, Investment
and Pay Deferral Plan Trust (the Trust) will continue until all of the funds
held by The Northern Trust Company (the Trustee) have been distributed to the
participants or their beneficiaries. Such distribution will be made in
accordance with the provisions of the Plan in effect on the date of its
termination.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES:
- - ---------------------------------------- 

Basis of Accounting
- - -------------------

The financial statements of the Plan are prepared on the accrual basis of
accounting, except for benefit payments to former participants which are
recorded when paid as noted below.

Withdrawals by Participants
- - ---------------------------

Withdrawals by participants includes benefit payments, transfers out of the
plan, and net loan activity.

Valuation of Investments
- - ------------------------

All investments, except for group annuity contract deposits, are valued by the
Trustee based on the closing market value on the last business day of the plan
year. The group annuity contract deposits are stated at estimated fair value,
which represents contributions made under the contracts at original cost plus
interest at the contract rate. The insurance companies are contractually liable
for the contract value provided the investment remains with the insurance
company.

Amounts Due Participants:
- - -------------------------

In accordance with ERISA requirements for reporting by employee benefit plans,
benefit payments to former participants are recorded when paid. Accordingly, at
December 31, 1995 and December 31, 1994, the following amounts have been
allocated to the individual accounts of former participants, but not recorded as
liabilities on the Statements of Net Assets Available for Plan benefits or
withdrawals by participants in the Statements of Changes in Net Assets Available
for Plan Benefits:

statements and the Form 5500 as these amounts have been recorded as liabilities
as of December 31, 1995 and 1994, and have been included in the benefits paid
for the respective years on the Form 5500.


NOTE 3 - PLAN AMENDMENTS:

In 1994, the Plan document was amended and restated to include the provisions
required by certain tax regulations. These amendments did not affect the
