At a Glance
  Union Carbide Corporation is a worldwide chemicals and polymers company. The 
company possesses many of the industry's most advanced process and catalyst 
technologies and some of the most cost efficient, large-scale production 
facilities in the world. In addition to its consolidated operations, the 
corporation participates in partnerships and joint ventures whose combined net 
sales totaled more than $4.3 billion in 1997.
  Union Carbide operates two business segments:
Specialties & Intermediates, which accounted for 68 percent of customer 
revenues and 64 percent of operating profit in 1997, produces a broad range of 
products, including specialty polyolefins used in wire and cable insulation; 
surfactants for industrial cleaners; catalysts for the manufacture of 
polymers; acrolein and derivatives; water-soluble polymers; cellulose-, 
glucose- and lanolin-based materials for personal care products; specialty 
coatings; acrylic and vinyl acrylic latex used in paints and adhesives; 
solvents; vinyl acetate monomer, and ethylene oxide derivatives. This segment 
also licenses olefins-based technologies and offers other specialized 
technology licensing and services.
  Basic Chemicals & Polymers converts various hydrocarbon feedstocks, 
principally liquefied petroleum gases and naphtha, into the basic building-
block chemicals ethylene and propylene (also known as olefins), which are in 
turn converted to polyethylene (the world's most widely used plastic), 
polypropylene (one of the world's fastest-growing plastics), and ethylene 
oxide and ethylene glycol (used to make polyester fiber, film and resin, and 
automotive antifreeze). This segment provides ethylene, propylene, ethylene 
oxide and ethylene glycol to the Specialties & Intermediates segment.

Chairman's Letter

(Contained in the left hand margin is a picture of William H. Joyce, Chairman, 
President and Chief Executive Officer.)

I am pleased to report that Carbide had another good year in 1997, surpassing 
the prior year and posting the third highest net income available to common 
stockholders of the past 10 years.
  Worldwide sales rose 6.5 percent, to $6.5 billion. Income available to 
common stockholders from continuing operations (before the effect of a change 
in accounting principle) rose 14.8 percent from the prior year, to $669 
million, and diluted per-share income increased 16.2 percent, to $4.53, before 
the change in accounting principle.
  Despite improved earnings, our 1997 common stock performance was 
disappointing. We increased the quarterly dividend 20 percent, to 22.5 cents, 
and repurchased 7 million shares during the year, but our share price 
increased only 5 percent by year-end. 
  It seems clear that investors were looking past improved earnings in 1997 
and focusing instead on the 1999/2000 cyclical trough anticipated by most 
experts, and on the widely held expectation that overcapacity in the chemical 
industry will depress the earnings of companies like Carbide until the cycle 
turns up. 
  Adding to investor concerns was the inability of our Specialties & 
Intermediates (S&I) segment, for the second year in a row, to deliver the 
strong double-digit earnings growth of prior years, causing investors to doubt 
that its recovery could occur in time to meet our earnings target in the 
trough. 
  And as the year ended, the Asian economic crisis appeared to make the next 
few years even more difficult for companies such as Carbide with significant 
sales in the region. Since the Far East region accounts for 14 percent of our 
sales, mainly exports, we are also concerned. Yet we're confident that Carbide 
can cope and that our company will be well positioned to participate when the 
region's growth resumes.
  As for 1997 performance, although we posted significant earnings growth, we 
should have done much better in light of our improvements over the past 
several years.
  Increases of 5.1 percent in volume and 3.7 percent in productivity for the 
corporation (based on actual fixed cost per pound of product sold, adjusted 
for inflation) were good, but below target. And some of our product lines, 
notably our solvents, monomers and industrial performance chemicals, were 
unable to deliver targeted results. 
  Why did we not do better in 1997? And what are we doing to improve and to 
accelerate profitable growth over the longer term as well? 
  Management's Discussion & Analysis, beginning on page 9, covers operations 
in detail. To summarize: The performance of solvents, monomers and industrial 
performance chemicals products suffered from price declines; abnormally low 
margins, particularly for solvents and monomers, and the impact of a strong 
dollar on exports.
  Although the strong dollar affected our Basic Chemicals & Polymers (BC&P) 
segment, as did problems with certain production units, segment earnings were 
much improved compared to 1996.

                                    - 2 -




  Startup costs for our huge new petrochemical joint venture in Kuwait also 
reduced earnings, as did costs associated with the delayed startup of a new 
facility for producing ethylene/propylene rubber (EPR). 
  The Kuwait plant is in the final stage of startup at this writing, with both 
ethylene glycol and polyethylene already shipped to customers in Europe and 
Asia. And the EPR plant, which uses proprietary new technology to achieve 
vastly lower production costs, is scheduled for restarting in the fourth 
quarter of 1998, although further modification is required before that can 
happen. 
  On the plus side, the drain on 1997 earnings was partly offset by improved 
pricing for ethylene glycol, and for polyethylene early in the year, and by 
the continuing, substantial benefit derived from our work process improvement 
and cost reduction programs over the past several years. 
  To say that Carbide has few peers when it comes to improving work processes 
and reducing costs is only repeating what's often been said by others who 
follow our progress. Since 1992, total fixed costs have dropped by nearly $8 
million, notwithstanding a $1.6 billion increase in revenues and a 27 percent 
increase in volume. Fixed cost per pound of product sold has dropped by 4.7 
cents since the beginning of the decade, a 30 percent decrease. In 1997, costs 
associated with the Kuwait and EPR startups and other unusual growth 
expenses reduced earnings by $0.72 per diluted share. Those expenses aside, 
the fixed cost improvements mean that, given margin conditions no better than 
the ones faced by BC&P in 1993, Carbide could have earned about three times as 
much per diluted share in 1997 as we earned in the 1993 trough.
  Over the past seven years, we have learned that productivity improvement 
requires relentless focus on cost reduction throughout the entire enterprise. 
During this period, virtually every unit within Carbide has established 
savings initiatives with specific, quantifiable targets. More often than not, 
as Carbiders have progressed with these efforts, new opportunities have been 
identified.
  In 1990 we embarked on a $200 million savings program. Less than three years 
into that effort, it was clear that far more significant savings were 
possible, and a $575 million target was established. That program, dubbed 
EQAI, was largely completed by the end of 1994, after we had achieved 
substantially all of the targeted savings. In 1995 we unveiled a new series of 
initiatives with targeted savings of $637 million, compared to 1993, to be 
achieved by the year 2000. Last October, after having attained a substantial 
portion of these targets, we increased the savings goal to $1.1 billion by the 
year 2000.
  Carbiders have time and again shown themselves dedicated to creating value 
by reducing costs. I am confident that over the next three years they will 
extend the progress they've made since early in the decade. They have become 
as skilled as any workforce anywhere at finding ways to improve work processes 
and reduce costs while delivering the service that our customers expect.
  On that score: We track customer evaluations of Carbide very closely, and 
it's clear that now, more than ever, our customers know they can count on 
Carbide people to deliver products, services and chemical expertise that add 
up to more value.
  Carbiders take a great deal of pride in those evaluations and in our profit 
improvement work. And, not incidentally, they also benefit financially as 
shareholders and profit sharing participants when our company does well. 
Beyond participation in the profit sharing program, most of our managers, 
including all senior managers, receive variable compensation based in large 
part upon our ability to realize returns on capital in excess of our 
competitors'.
  While there can be no assurances, if we are successful in achieving our 
savings targets, we believe that it will be possible also to earn 
at least $4.00 per diluted share in both 1999 and 2000, the anticipated trough 
years of the current commodity chemical cycle.
  To leave no doubt about management's own commitment to doing what it takes 
to reach these earnings levels, we have bet a large part of our pay on 
reaching them. If we fail in 2000, I will forfeit the equivalent of a year's 
salary, and 16 members of our senior management team each will forfeit the 
equivalent of 65 percent of a year's base pay. If we succeed, the plan, which 
investors have encouraged us to implement, has a substantial upside 
opportunity to go along with the risk. 
  In other words, Carbide management has real incentive to reach the target.
  Although we are committed to our volume growth and savings targets, reaching 
them will not be easy or assured. But work is under way across our worldwide 
locations to improve operations, further streamline work processes and make 
the most of our strong market and technology positions. And much has already 
been accomplished. 
  To cite just a few examples: 1997 cost savings in our S&I segment of $336 
million, and savings of $302 million for BC&P, kept

                                    - 3 -




us ahead of schedule toward our year-2000 cost reduction target. 
  Regarding programs designed to promote growth, we launched Univation 
Technologies, our joint venture with Exxon Chemical Company, to develop and 
license leading-edge polyethylene process and catalyst technologies. Companies 
in South America and Europe recently selected its technology to build 1.8 
billion pounds of capacity.
  A major modernization of our UCON fluids manufacturing unit in 1997 
increased capacity while cutting operating costs, and the fluids business was 
named a "supplier of the year" by General Motors, whose cars use our UCON 
brake fluids and UCON refrigeration lubricants.
  At our Taft, La., plant, we completed a 200-million-pound-capacity 
ethanolamines unit, strengthening our leading position as a supplier to the 
gas treating and personal care markets. Also at Taft, we are scheduled to 
complete by mid-1998 a new CARBOWAX polyethylene glycols (PEGs) facility to 
support sales flowing from new PEG applications in pharmaceuticals and wood 
treating.
  Our polypropylene units ran at high rates during the year, with added 
capacity, achieved through de-bottlenecking, that will help the 
business meet its year-2000 growth targets.
  Construction began at Taft on a new butanol facility, planned for startup in 
mid-1999, that will bring Carbide's total butanol capacity to 1.2 billion 
pounds, the world's largest. Butanol is a key raw material in the manufacture 
of solvents and monomers used by the paints and coatings industries. Employing 
our proprietary LP OXO Process technology, the 300-million-pounds-per-year 
facility is designed to be among the world's most cost effective. 
  Dr. David Bryant, the Carbide scientist who played a key role in developing 
OXO technology, has been named 1998 winner of the Perkin Medal - one of the 
chemical industry's most prestigious honors - for his achievement.
  In 1997 we expanded capacity for producing propionic acid, a key ingredient 
in the production of feed and food additives, herbicides and chemical 
intermediates.
  We are completing modernization of our ethylene oxide and derivatives units 
at Wilton in the United Kingdom, and a new glycol unit is on schedule for 
second-quarter 1998 startup. And we are concluding new long-term glycol supply 
agreements to support the added capacity represented by Wilton and our EQUATE 
joint venture in Kuwait. 
  Work is also under way to expand capacity at Seadrift, Tex., and at Wilton, 
for butyl glycol ethers, widely used in industrial coatings and as industrial 
cleaners. In addition, we have just announced plans to build a world-scale 
methylmercapto propionaldehyde (MMP) unit at Seadrift. This unit will supply 
MMP, an amino acid precursor, to Novus International for the manufacture of a 
feed supplement.
  We are confident that these and many other projects undertaken in 1997 will 
help to keep us on course toward our near-term growth and profitability 
targets.  
  Our parallel agenda as a RESPONSIBLE CARE company is to keep improving 
Carbide's environmental and safety performance. The year just ended marked six 
years in a row without a major process incident. But there were 
disappointments as well, chiefly a death that occurred in a forklift accident 
- - at a latex plant of a Union Carbide affiliate company in China - after five 
consecutive years without a fatality in any of our operations. 
  (For more information about our 1997 environmental and safety performance, 
write to Carbide's Public Affairs Department for our RESPONSIBLE CARE progress 
report.)
  All of us were pleased and proud to have our TRITON surfactants business 
receive two environmental awards in 1997. One, from the Environmental 
Protection Agency (EPA), recognized Carbide's TRITON splittable surfactants as 
an innovation in surfactant chemistry that greatly reduces risk to the aquatic 
environment. The other, from the Office of the Vice President of the U.S., 
recognized the TRITON surfactant-based partnership we entered into with the 
EPA to control environmental risk so that more regulation and its cost to 
business and the public would become unnecessary.   Finally, I wish to applaud 
two of our directors - John Creedon and Bill Sneath - who, in accordance with 
the board's retirement policy, will not stand for reelection. Both have given 
outstanding service to the corporation, with Bill's tenure including 31 years 
of service as an employee, five of those as Chairman and CEO. We will miss 
their support and wise counsel.

Basic Chemicals & Polymers Segment
Union Carbide's Hydrocarbons group manufactures about two thirds of the 
company's ethylene requirements and almost one third of its propylene 
requirements. Ethylene and propylene are the key raw materials for many of 
Union Carbide's businesses.

Union Carbide is the world's leading producer of ethylene oxide and ethylene 
glycol, supplied by the Ethylene Oxide/Glycol group. Ethylene oxide is a 
chemical intermediate primarily used in the manufacture of ethylene glycol, 
polyethylene glycol, glycol ethers, ethanolamines, surfactants and other 
performance chemicals and polymers. Ethylene glycol is used extensively in the 
production of polyester fiber, resin and film, automotive antifreeze and 
engine coolants, and aircraft anti-icing and deicing fluids. Other ethylene 
oxide-based glycol products include di-, tri-, and tetraethylene glycols, used 
as chemical intermediates and in dehydrating natural gas.

Union Carbide is a leading manufacturer of polyethylene, the world's most 
widely used plastic. UNIPOL Polymers produces and markets linear low-, medium- 
and high-density polyethylenes, used in high-volume applications such as 
housewares, milk and water bottles, grocery sacks, trash bags, packaging, 
water and gas pipe, and FLEXOMER very low-density resins, used as a polymer 
modifier in other polyolefins and to produce flexible hose and tubing, frozen-
food bags and stretch wrap. 

Carbide's Polypropylene Resins operations manufacture and sell polypropylene, 
one of the world's largest-volume, fastest-growing plastics. End-use 
applications include carpeting and upholstery, apparel, packaging films, food 
containers, housewares and appliances, and automobile interior trim and 
panels.

Summary and Outlook
  Union Carbide operates two business segments. Specialties & Intermediates 
converts basic and intermediate chemicals into a diverse portfolio of 
chemicals and polymers serving industrial customers in many markets. This 
segment also provides technology services, including licensing, to the oil and 
petrochemicals industries. Basic Chemicals & Polymers converts hydrocarbon 
feedstocks, principally liquefied petroleum gas and naphtha, into ethylene or 
propylene and then into polyethylene, polypropylene, ethylene oxide and 
ethylene glycol for sale to third-party customers, as well as ethylene, 
propylene, ethylene oxide and ethylene glycol for consumption by the 
Specialties & Intermediates segment. In contrast to those of Specialties & 
Intermediates, the revenues and operating profit of Basic Chemicals & Polymers 
tend to be more cyclical and very sensitive to a number of external variables, 
including overall economic demand, hydrocarbon feedstock costs, industry 
capacity increases and plant operating rates.

  Segment results were mixed in 1997 with Basic Chemicals & Polymers reporting 
substantially improved operating profit as compared with 1996 while 
Specialties & Intermediates operating profit decreased 10.1 percent. The Basic 
Chemicals & Polymers business benefited from increased ethylene glycol prices 
throughout the first three quarters of 1997 and improved polyethylene pricing 
through the first half of the year. In addition, the segment experienced 
reduced average feedstock costs versus 1996. Specialties & Intermediates 
operating profit was adversely impacted by increased raw material costs, most 
significantly ethylene oxide transferred from the Basic Chemicals & Polymers 
segment at approximate market value, higher energy costs and shipment 
disruptions associated with railroad problems in the U.S. Gulf Coast region. 
Average selling prices for the Specialties & Intermediates segment were 
negatively impacted by a much stronger U.S. dollar as well as by increased 
competition, principally in the segment's solvents, intermediates and 
monomers product lines. On a consolidated basis, sales volumes increased by 
5.1 percent, while fixed cost per pound sold declined to 10.8 cents, the 
lowest of this decade. Partnership income remained strong, excluding certain 
costs, principally research and development, assumed by our new technology 
venture, Univation Technologies, LLC. Additionally, the improved earnings from 
our equity companies represented increases in earnings of Polimeri Europa 
partially offset by increased preoperating expenses associated with EQUATE 
Petrochemical Company.
  In 1996 the corporation's earnings were adversely impacted by declines in 
selling prices, particularly for ethylene glycol, polyethylene and vinyl 
acetate monomer, and by high raw material and energy costs. These factors 
significantly impacted Basic Chemicals & Polymers operating profit and limited 
Specialties & Intermediates operating profit growth. Sales volumes experienced 
their largest increase in the past decade, while productivity, as measured by 
fixed cost per pound of product sold, also improved. Partnerships continued to 
report strong profits, while equity company results declined due to the 
preoperating costs of EQUATE and increased raw material costs for Polimeri 
Europa.

  In 1995 the corporation's profitability benefited from improved pricing in 
virtually all product groups, with particular strength in polyethylene through 
midyear and ethylene oxide and ethylene glycol throughout the year, modest 
volume increases, lower average feedstock costs, continued benefits from 
ongoing productivity improvement programs and strong partnership earnings. In 
addition, 1995 net income was enhanced by a nonrecurring after-tax gain 
associated with the sales of the corporation's investment in UCAR 
International Inc., partially offset by a number of nonrecurring after-tax 
losses.

Highlights of 1997 included:
o Completion of an ethanolamines unit at Taft, La.
o Startup of the EQUATE facility in Shuaiba, Kuwait
o Formation of Univation Technologies, LLC, a 50-50 joint venture with Exxon 
Chemical Company to research, develop, market and license leading-edge 
technologies and metallocene catalysts for the production of polyethylene
o Signing of a joint undertaking with NOVA Chemicals, Ltd., to construct, own 
and operate a new 2.8-billion-pounds-per-year ethylene production facility in 
Joffre, Alberta, Canada
o Increase in the quarterly dividend per common share from $0.1875 to $0.225
o Repurchase of 7.0 million common shares, bringing the total number of shares 
repurchased since the beginning of 1993 to 49.3 million
o Conversion of preferred shares held by the Employee Stock Ownership Plan 
(ESOP) into the corporation's common shares
o Announcement of a new plan to increase the target for annual net savings to 
$1.1 billion by year-end 2000, as compared with 1993, and better-than-planned 
progress toward achievement of this target

  As 1998 progresses, pricing for Basic Chemicals & Polymers products is 
expected to continue to decline. The pace and extent of the drop cannot be 
predicted with any accuracy and is dependent in part on developments in Asian 
Pacific economies, which are major markets for these products. Feedstock costs 
are expected to decline at least modestly from fourth quarter 1997 levels. 
Specialties & Intermediates operating profit in 1998 should benefit somewhat 
from a decline in raw material and energy prices. Moreover, the corporation 
expects continued strong performance from the Specialties & Intermediates 
partnerships as a group, and from licensing activities. However, as is the 
case with Basic Chemicals & Polymers, the ability to anticipate future results 
with any accuracy is dependent on the resolution and stabilization of Asian 
Pacific market conditions.

                                    - 10 -




  The corporation regularly reviews its assets with the objective of 
maximizing the deployment of resources in core operations. In this regard, UCC 
continues to consider strategies and/or transactions with respect to certain 
noncore assets and other assets not essential to the operation of the business 
that, if implemented, could result in material nonrecurring gains or losses.

Quantitative and Qualitative Disclosures About Market Risk
  The corporation selectively uses derivative financial instruments to manage 
its exposure to market risk related to changes in foreign currency exchange 
rates and interest rates. The corporation does not hold derivatives for 
trading purposes. The value of market sensitive derivative instruments is 
subject to change as a result of movements in market rates and prices. 
Sensitivity analysis is one technique used to evaluate these impacts. Based on 
a hypothetical 10 percent weakening in the U.S. dollar across all currencies 
or a 10 percent increase in interest rates, the potential losses in future 
earnings, fair values and cash flows would not be material. This methodology 
has limitations; for example, a weakening U.S. dollar would benefit future 
earnings through favorable translation of non-U.S. operating results.

Foreign Operations
  A portion of the financial results of each of the corporation's segments is 
derived from activities conducted outside the U.S. and denominated in 
currencies other than the U.S. dollar. Because the financial results of the 
corporation are reported in U.S. dollars, they are affected by changes in the 
value of the various foreign currencies in relation to the U.S. dollar. 
Exchange rate risks are lessened, however, by the diversity of the 
corporation's foreign operations and the fact that international activities 
are not concentrated in any single non-U.S. currency. In addition, the effects 
of a strengthening U.S. dollar could cause pricing pressures on worldwide 
chemical markets which could result in declines in the corporation's sales 
volumes.
  The corporation is subject to other risks customarily associated with doing 
business in foreign countries, including local labor and economic conditions, 
unfavorable changes in foreign tax laws, and possible controls on repatriation 
of earnings and capital. Future losses associated with such risks, if any, 
cannot be predicted.

1997 Compared with 1996
Sales of the Specialties & Intermediates segment increased 3.9 percent, as a 
result of a 6.7 percent increase in volume offset by lower average selling 
prices. Average selling price reductions were due in part to a strengthening 
of the U.S. dollar against currencies such as the German Deutschemark and 
Japanese Yen, as well as by increased competition in solvents, intermediates 
and monomers product lines. Additionally, shipments for this segment's 
products were affected by rail problems in the U.S. Gulf Coast region. 
Variable margin (revenues less variable manufacturing and distribution costs) 
as a percentage of sales declined 2.2 percentage points, from 44.6 percent in 
1996 to 42.4 percent in 1997, while gross margin (variable margin less fixed 
manufacturing and distribution costs) as a percentage of sales declined 2.4 
percentage points to 24.6 percent in 1997. Increases in the market-related 
transfer cost of raw materials produced by the Basic Chemicals & Polymers 
segment, as well as the increasing cost of natural gas, significantly affected 
these margins. Fixed manufacturing and distribution costs for this segment 
increased 5.3 percent, or $40 million, from the previous year's levels.
  Selling, administration and other expenses (SA&O) for this segment decreased 
$5 million, or 2.0 percent. Research and development expenditures decreased $2 
million, to $126 million, mainly attributable to costs assumed by the 
corporation's new technology venture, Univation Technologies.
  Operating profit decreased $75 million, or 10.1 percent, to $667 million 
from $742 million in 1996. The current year operating profit includes a charge 
of $12 million for the write-off of certain equipment associated with the 
corporation's ethylene propylene rubber project.

1996 Compared with 1995
  Revenues of the Specialties & Intermediates segment increased 4.0 percent, 
the result of an 8.9 percent increase in volume partially offset by a 4.7 
percent decline in average selling prices. The reduction in average selling 
prices reflected the combined effect of increases in

                                    - 11 -




sales of lower priced products and declines in prices of certain products from 
the unusually high levels experienced in 1995. Variable margin as a percentage 
of sales dropped by 1.6 percentage points, from 46.2 percent in 1995 to 44.6 
percent in 1996, while gross margin as a percentage of sales declined by 0.8 
percentage points, to 27.0 percent in 1996 from 27.8 percent in 1995. Fixed 
manufacturing and distribution costs were held at 1995 levels.
  The segment's 1996 SA&O decreased $45 million, or 15.1 percent, because of 
the inclusion in 1995 SA&O of a nonrecurring $48 million charge for 
postemployment benefits. Excluding this charge, SA&O increased $3 million, or 
1.2 percent. Research and development expenditures increased $14 million, to 
$128 million.
  Operating profit increased in 1996 to $742 million from $709 million in 
1995.

1997 Compared with 1996
  Sales of the Basic Chemicals & Polymers segment increased 13.9 percent, 
largely as a result of a 9.2 percent increase in average customer selling 
price coupled with a 3.2 percent increase in customer volume. The increase in 
average customer selling price reflects the strong increase in ethylene glycol 
pricing during the first three quarters of 1997 and improved polyethylene 
pricing throughout the first half of the year. Variable margin as a percentage 
of sales increased to 39.9 percent from 34.6 percent in 1996. Overall, this 
segment benefited from an increase in gross margin as a percentage of sales to 
25.0 percent, compared with only 18.2 percent in 1996. Fixed manufacturing and 
distribution costs increased by 3.7 percent.
  The segment's SA&O increased $8 million, or 11.9 percent, over the 1996 
amount. Research and development expenditures were unchanged from the prior 
year.
  Operating profit of $386 million in 1997 represented an increase of over 100 
percent from the prior year.

1996 Compared with 1995
  Revenues of the Basic Chemicals & Polymers segment increased 2.2 percent, 
due to a 14.1 percent increase in customer volume, 11.5 percent of which was 
due to the January 1996 acquisition of the polypropylene business of Shell Oil 
Company, offset by a 9.7 percent decrease in selling prices. Variable margin 
as a percentage of sales declined from 46.4 percent in 1995 to 34.6 percent in 
1996. Ethylene glycol selling prices declined throughout the first three 
quarters of 1996. While polyethylene prices improved beginning in the second 
quarter of 1996, they nonetheless averaged below 1995 levels for the full 
year. Raw material and energy costs rose during 1996, especially in the fourth 
quarter. Gross margin as a percentage of sales declined to 18.2 percent in 
1996 as compared with 30.8 percent in 1995. Fixed manufacturing and 
distribution costs increased $24 million, or 7.4 percent, from 1995 to 1996, 
principally due to the acquisition of Shell's polypropylene assets and 
business.
  SA&O decreased $20 million, or 23.0 percent, versus 1995. Prior year SA&O 
included a nonrecurring $20 million charge for postemployment benefits. 
Research and development expenditures increased $1 million, to $31 million.
  Operating profit declined to $162 million in 1996 from $444 million in 1995.

  The Other segment includes the operating profit (loss) of noncore activities 
and financial transactions. The 1995 operating profit included a nonrecurring 
pre-tax gain of $381 million from the sales of the corporation's remaining 
interest in UCAR International Inc., partially offset by a $191 million charge 
for unused office space, principally at the corporation's headquarters. 

Costs Relating to Protection of the Environment
Worldwide costs relating to environmental protection continue to be 
significant, due primarily to stringent laws and regulations and to 
the corporation's commitment to industry initiatives such as RESPONSIBLE CARE, 
as well as to its own internal standards. In 1997, worldwide expenses related 
to environmental protection for compliance with Federal, state and local laws 
regulating solid and hazardous wastes and discharge of materials to air and 
water, as well as for waste site remedial activities, totaled $100 million. 
Expenses in 1996 and 1995 were $110 million and $138 million, respectively. 
Such expenses were material to operating results in 1997, 1996 and 1995, and 
will be material to operating results in future years. In recent years, such 
environmental expenses have decreased as the corporation has made progress 
toward completing major remediation projects. In addition, worldwide capital 
expenditures relating to 

                                    -12 -




environmental protection, including those for new capacity and cost reduction 
and replacement, in 1997 totaled $68 million, compared with $43 million and 
$49 million in 1996 and 1995, respectively.
  The corporation, like other companies in the U.S., periodically receives 
notices from the U.S. Environmental Protection Agency and from state 
environmental agencies, as well as claims from other companies, alleging that 
the corporation is a potentially responsible party (PRP) under the 
Comprehensive Environmental Response, Compensation and Liability Act and 
equivalent state laws (hereafter referred to collectively as Superfund) for 
past and future cleanup costs at hazardous waste sites at which the 
corporation is alleged to have disposed of, or arranged for treatment or 
disposal of, hazardous substances. The corporation is also undertaking 
environmental investigation and remediation projects at hazardous waste sites 
located on property currently and formerly owned by the corporation pursuant 
to Superfund, as well as to the Resource Conservation and Recovery Act and 
equivalent state laws.
  There are approximately 117 hazardous waste sites at which management 
believes it is probable or reasonably possible that the corporation will incur 
liability for investigation and/or remediation costs. The corporation has 
established accruals for those hazardous waste sites where it is probable that 
a loss has been incurred and the amount of the loss can reasonably be 
estimated. The reliability and precision of the loss estimates are affected by 
numerous factors, such as the stage of site evaluation, the allocation of 
responsibility among PRPs and the assertion of additional claims. The 
corporation adjusts its accruals as new remediation requirements are defined, 
as information becomes available permitting reasonable estimates to be made, 
and to reflect new and changing facts.
  At Dec. 31, 1997, the corporation's accruals for environmental remediation 
totaled $264 million ($310 million in 1996). Approximately 55 percent of the 
accrual (58 percent in 1996) pertains to estimated future expenditures for 
site investigation and cleanup, and approximately 45 percent (42 percent in 
1996) pertains to estimated expenditures for closure and postclosure 
activities. See note seventeen to the financial statements for a discussion of 
the environmental sites for which the corporation has remediation 
responsibility. In addition, the corporation had environmental loss 
contingencies of $159 million at Dec. 31, 1997. 
  Estimates of future costs of environmental protection are necessarily 
imprecise, due to numerous uncertainties. These include the impact of new laws 
and regulations, the availability and application of new and diverse 
technologies, the identification of new hazardous waste sites at which the 
corporation may be a PRP and, in the case of Superfund sites, the ultimate 
allocation of costs among PRPs and the final determination of the remedial 
requirements. While estimating such future costs is inherently imprecise, 
taking into consideration the corporation's experience to date regarding 
environmental matters of a similar nature and facts currently known, the 
corporation estimates that worldwide expenses related to environmental 
protection, expressed in 1997 dollars, should average about $110 million 
annually over the next five years. Worldwide capital expenditures for 
environmental protection, also expressed in 1997 dollars, are expected to 
average about $50 million annually over the same period. Management 
anticipates that future annual costs for environmental protection after 2002 
will continue at levels comparable to the five-year average estimates.
  Subject to the inherent imprecision and uncertainties in estimating and 
predicting future costs of environmental protection, it is management's 
opinion that any future annual costs for environmental protection in excess of 
the five-year average estimates stated here, plus those costs anticipated to 
continue thereafter, would not have a material adverse effect on the 
corporation's consolidated financial position. 

Litigation
  The corporation and its consolidated subsidiaries are involved in a number 
of legal proceedings and claims with both private and governmental parties. 
These cover a wide range of matters, including, but not limited to, product 
liability; governmental regulatory proceedings; health, safety and 
environmental matters; employment; patents; contracts, and taxes. In addition, 
the corporation continues to be named as one of a number of defendants in 
lawsuits involving silicone breast implants. The corporation supplied bulk 
silicone materials to certain companies that at various times were involved in 
the manufacture of breast implants. These cases are discussed in more detail 
in note seventeen to the financial statements. In some of these legal 
proceedings and claims, the cost of remedies that may be sought or damages 
claimed is substantial. While it is impossible at this time to determine with 
certainty the ultimate outcome of any such legal proceedings and claims, 
management believes that adequate provisions have been made for probable 
losses with respect thereto and that such ultimate outcome, after provisions 
therefor, will not have a material adverse effect on the consolidated 
financial position of the corporation but could have a material effect on 
consolidated results of operations in a given quarter or year. Should any 
losses be sustained in connection with any of such legal proceedings and 
claims in excess of provisions therefor, they will be charged to income in 
the future.

Specialties & Intermediates
  The corporation's share of the net income of Specialties & Intermediates 
partnerships and joint ventures decreased $21 million in 1997. This decline 
resulted from the assumption of certain costs, principally research and 
development, by the corporation's new technology venture, Univation 
Technologies, and decreased earnings of World Ethanol, mainly attributable to 
lower prices and volumes caused by a different mix of ethanol sales in 1997.
  Increased earnings in 1996, as compared with 1995, resulted from increased 
earnings from UOP being partially offset by the elimination of earnings of the 
polypropylene partnership with Shell Oil Company. The 1996 and 1997 earnings 
from the polypropylene business were included in the consolidated results.

Basic Chemicals & Polymers
  The corporation's share of the net income of Basic Chemicals & Polymers 
partnerships and joint ventures increased $29 million from 1996 to 1997, due 
to significant improvement in Polimeri Europa and Petromont earnings, offset 
by increased preoperating expenses EQUATE. Strong results of our polyolefins 
partnerships in 1997 were the result of increases in worldwide polymer pricing 
over the prior year. The decrease from 1995 to 1996 reflected losses from 
Polimeri Europa and decreased earnings from Petromont, caused by lower 
polyethylene prices and higher raw material costs, and the recognition of 
preoperating expenses of EQUATE.
  EQUATE Petrochemical Company commenced operations in the fourth quarter of 
1997. Losses of $43 million for development of this world-scale petrochemical 
complex were recognized by the corporation in 1997 ($23 million and $3 million 
in 1996 and 1995, respectively). The corporation has severally guaranteed 45 
percent (approximately $606 million at Dec. 31, 1997) of EQUATE's debt and 
working capital financing needs until certain completion and financial tests 
are achieved. If these tests are met, a $54 million several guarantee will 
provide ongoing support thereafter. The corporation also severally guaranteed 
certain sales volume targets until EQUATE's sales capabilities are proved. In 
addition, the corporation has pledged its shares in EQUATE as security for 
EQUATE's debt. The corporation has political risk insurance coverage for its 
equity investment and, through Sept. 30, 1998, substantially all of its 
several guarantee of EQUATE's debt. 

Other
  The corporation's remaining interest in UCAR International Inc., a 
manufacturer of carbon and graphite products, was sold in 1995. Income (loss) 
from corporate investments carried at equity included $4 million in 1995, 
representing the corporation's share of UCAR's earnings in that year. 
Additionally, the corporation's share of dividends and distributions from UCAR 
was $5 million in 1995.

Interest Expense
  Interest expense increased $3 million, from $76 million in 1996 to $79 
million in 1997. This increase reflects the effect of a full year's interest 
expense associated with the 7.75 percent debentures due in 2096 and an 
increase in short-term debt, partially offset by an increase in capitalized 
interest associated with the corporation's capital program. Interest expense 
decreased $13 million from 1995 to 1996 as a result of increased capitalized 
interest. 

Provision for Income Taxes
  The effective tax rate was 28.9 percent in 1997 compared with 27.9 percent 
and  30.2 percent in 1996 and 1995, respectively. The corporation's effective 
tax rate was reduced in each of these years as a result of foreign sales 
corporation income taxed at a preferential rate and research and 
experimentation tax credits. The 1995 effective tax rate was increased as a 
result of taxes provided on the sale of UCAR International Inc.

Accounting Changes
1995 through 1997
  In November 1997, the Emerging Issues Task Force reached consensus on Issue 
97-13, "Accounting for Costs Incurred in Connection with a Consulting Contract 
or an Internal Project That Combines Business Process Reengineering and 
Information Technology Transformation," requiring companies to expense as 
incurred costs associated with business process reengineering activities. 
Effective Oct. 1, 1997, the corporation adopted the provisions of Issue 97-13 
as a cumulative effect of a change in accounting principle, reversing 
$28 million ($17 million, after-tax) of costs previously capitalized from 1995 
through the third quarter of 1997. 
  Additionally in 1997, the corporation adopted Statement of Financial 
Accounting Standards (SFAS) 128, "Earnings Per Share", and SFAS 129, 
"Disclosure of Information About Capital Structure." In 1996, the corporation 
adopted SFAS 123, "Accounting for Stock-Based Compensation," under which the 
corporation elected to continue following Accounting Principles Board Opinion 
25. In 1995, the corporation adopted SFAS 121, "Accounting for the Impairment 
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the effect 
of which was not material. 

                                    - 15 -




1998
  In June 1997, the Financial Accounting Standards Board issued SFAS 130, 
"Reporting Comprehensive Income," and SFAS 131, "Disclosures About Segments of 
an Enterprise and Related Information," for fiscal years beginning after Dec. 
15, 1997. These statements address presentation and disclosure matters and 
will have no impact on the corporation's financial position or results of 
operations. The corporation does not anticipate a change in the identification 
of its business segments.
  Effective Jan. 1, 1998, Brazil was no longer considered to be a highly 
inflationary economy. Had this change occurred effective Jan. 1, 1997, the 
effect on results of operations and financial position would not have been 
material.

Year 2000 Issue
  Most of the corporation's computer and process control systems were designed 
to use only two digits to represent years. Thus they may not recognize "00" as 
representing the year 2000, but rather 1900, which could result in errors or 
system failures. These systems must be corrected in a timely manner to remain 
functional.
  The corporation is addressing the year 2000 issue in several ways. Since 
1995, the corporation has expended significant funds to upgrade the bulk of 
its commercial computer systems to enhance the information available to the 
corporation. This upgrade will correct the year 2000 issue for the computer 
systems it replaces. The upgrade will be implemented in three parts, the first 
of which commenced operation in 1998. The remaining parts are scheduled for 
operation by year-end. The corporation is reviewing the balance of its 
domestic and international internal processes, including hardware, software 
and control systems, and is assessing its external relationships to address 
potential impacts arising from interfaces with customers, suppliers and 
service providers. Priorities are being set and required system modifications 
are progressing. The corporation estimates its worldwide expenses related to 
the year 2000 project could range between $20 and $50 million over the next 
two years. The corporation believes the year 2000 project will be completed 
prior to the year 2000. However, considerable work remains to be accomplished 
in a limited period of time and unforeseen difficulties may arise which could 
adversely affect the corporation's ability to complete its systems 
modifications correctly, completely, on time and/or within its cost estimate. 
In addition, there can be no assurance that customers, suppliers and service 
providers on which the corporation relies will resolve their year 2000 issues 
accurately, thoroughly and on time. Failure to complete the year 2000 project 
by the year 2000 could have a material adverse effect on future operating 
results or financial condition.

Liquidity, Capital Resources and Other Financial Data
Cash Flow From Operations
  Cash flow from operations increased by $55 million to $917 million in 1997,
as compared with $862 million in 1996. Increased earnings for the year were 
offset by increases in working capital, principally the result of an increase 
in inventory partially offset by a decrease in notes and accounts receivable.

Cash Flow Used for Investing
  Cash flow used for investing includes capital expenditures, investments, 
advances and acquisitions, and proceeds from the sale of investments and 
assets.
  Capital expenditures increased to $755 million in 1997, from $721 million in 
1996 and $542 million in 1995. Major capital projects funded during 1997 
included a new CARBOWAX polyethylene glycol and TERGITOL surfactants facility, 
an ethanolamines unit and olefins expansion, all at Taft, La., as well as a 
continuing upgrade of the information technology infrastructure. Major capital 
projects funded during 1996 included an ethylene propylene rubber facility at 
Seadrift, Tex., expansion of ethylene production units at Taft, La., as well 
as new cogeneration facilities at Texas City, Tex. and Taft, La., and new 
information technology infrastructure. Major capital projects funded during 
1995 included a new butanol unit at Taft, La., an energy systems upgrade at 
Texas City, Tex., new TRITON surfactants production facilities at South 
Charleston, W.Va. and a new UNIPOL II polyethylene production facility at 
Taft, La.
  Over the past three years 52 percent of capital expenditures was directed to 
new capacity, 44 percent to cost reduction and replacement, and 4 percent to 
environmental, safety and health facilities. Of these expenditures, 92 percent 
was in the U.S. and Puerto Rico.
  Investments and acquisitions in 1996 included the purchases of Shell's 
polypropylene assets and business and of 95 percent of the outstanding shares 
of Companhia Alcoolquimica Nacional, a Brazilian producer of vinyl acetate 
monomer. Investments and acquisitions during 1995 included the $216 million 
acquisition of a 50 percent interest in Polimeri Europa, a $134 million 
investment in the EQUATE joint venture, and the $71 million purchase of 
certain ethylene oxide derivative businesses in the U.K. 
  Net proceeds from the sale of investments in 1995 included $542 million from 
the sales of the corporation's remaining interest in UCAR International Inc. 

                                    - 16 -




  At Dec. 31, 1997, the cost of completing authorized construction projects 
was estimated to be $1.375 billion, of which $50 million is covered by firm 
commitments. Future construction expenditures are anticipated to be sourced 
through operating cash flows and borrowings.

Cash Flow Used for Financing
  Cash flow used for financing includes stockholder and minority interest 
dividends and funds used to buy back common stock, offset in part by net 
proceeds from short- and long-term debt and sales of common stock pursuant to 
the corporation's dividend reinvestment plan and its employee savings and 
investment programs.
  Cash flow used for financing in 1997 totaled $132 million, compared with 
$254 million in 1996 and $57 million in 1995. Net borrowings totaled $306 
million, while cash dividends totaled $134 million.
  In January 1997, a newly formed real estate investment trust (REIT) 
subsidiary issued $250 million of preferred stock bearing a current dividend 
yield of 14 percent for 10 years and 1 percent thereafter. In October 1997, 
the corporation paid $240 million in cash to redeem the preferred stock 
shares. Cash dividends paid to preferred shareholders of the REIT during 1997 
totaled $25 million. 
  In September 1997, the board of directors declared an increase in the 
quarterly common stock dividend to $0.225 per share. In October 1997, the 
trustee of the Employee Stock Ownership Plan (ESOP) exercised its right to 
convert all shares of the corporation's preferred stock held by the ESOP into 
the corporation's common stock. This noncash conversion increased the 
corporation's common stock outstanding at that time by 15.4 million shares.
  In 1996, the corporation issued $200 million of 7.75 percent debentures 
maturing in 2096, the proceeds of which were used to finance ongoing share 
repurchases and to pay down existing short-term debt. In 1995 the corporation 
completed a $400 million, two-part public offering of debt securities. 
  On July 23, 1997, the corporation's board of directors authorized an 
increase in the number of shares that may be repurchased under the existing 
common stock repurchase program by 10 million shares, to an aggregate of 60 
million shares since inception of the program. During 1997, pursuant to the 
share repurchase program, the corporation repurchased 7.0 million shares of 
its common stock for $337 million, at an average effective price of $47.62 per 
share, bringing the total amount repurchased since the beginning of 1993 to 
49.3 million shares for $1.713 billion, at an average effective price of 
$34.69 per share. The corporation intends to acquire additional shares from 
time to time at prevailing market prices, at a rate consistent with the 
combination of corporate cash flow and market conditions.
  At Dec. 31, 1997, there were no outstanding borrowings under either the 
corporation's existing $1 billion bank credit agreement or its $500 million 
medium-term note program.

Debt Ratios
  Total debt outstanding at year-end for the past three years was:
Millions of dollars    1997      1996      1995
Domestic             $1,719    $1,492    $1,254
International           168       107        69
Total                $1,887    $1,599    $1,323

  Year-end ratios of total debt to total capital were:
                       1997      1996      1995
Debt ratio             44.2%     42.7%     39.0%

  Total debt consists of short-term debt, long-term debt and the current 
portion of long-term debt. Total capital consists of total debt plus minority 
stockholders' equity in consolidated subsidiaries and stockholders' equity.

a) Selling, administration and other expenses in 1995 include a charge of $68 
   million for postemployment benefits. 
b) Return on capital is computed by dividing income by beginning-of-year 
   capital. Income consists of income from continuing operations, less 
   preferred dividends, plus after-tax interest cost (net of interest income 
   received from Praxair), plus income attributable to minority interests. 
   Capital consists of total debt plus minority stockholders' equity in 
   consolidated subsidiaries and stockholders' equity, adjusted for the 
   corporation's Praxair-related assets and the cumulative effect of changes 
   in accounting principles. Total debt consists of short-term debt, long-term 
   debt and the current portion of long-term debt.
c) Prices are based on New York Stock Exchange Composite Transactions. 
d) In 1992 the corporation spun off Praxair, Inc. The high and low presented 
   in the table for 1992 represent the value of the common stock after the 
   spin-off. The high and low for 1992 before the spin-off were $29.63 and 
   $20.13, respectively. 
e) Return on equity is computed by dividing net income (loss)-common 
   stockholders by beginning-of-year stockholders' equity.

ONE
Summary of Significant Accounting Policies
Nature of Operations  o  Union Carbide Corporation is engaged in two segments 
of the chemicals and plastics industry, Specialties & Intermediates and Basic 
Chemicals & Polymers. See note five.

Principles of Consolidation  o  The consolidated financial statements include 
the accounts of all significant subsidiaries. All significant intercompany 
transactions have been eliminated in consolidation. Investments in 20 percent- 
to 50 percent-owned companies and partnerships are carried at equity in net 
assets. Other investments are carried generally at cost.
  The consolidated financial statements have been prepared in conformity with 
generally accepted accounting principles, which require the corporation 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.

Accounting Changes  o  In November 1997, the Emerging Issues Task Force 
reached consensus on Issue 97-13, "Accounting for Costs Incurred in Connection 
with a Consulting Contract or an Internal Project That Combines Business 
Process Reengineering and Information Technology Transformation," requiring 
companies to expense as incurred costs associated with business process 
reengineering activities. Effective Oct. 1, 1997, the corporation adopted the 
provisions of Issue  97-13 as a cumulative effect of a change in accounting 
principle, reversing $28 million ($17 million, after tax) of costs previously 
capitalized from 1995 through the third quarter of 1997.
  Additionally in 1997, the corporation adopted Statement of Financial 
Accounting Standards (SFAS) 128, "Earnings Per Share," and SFAS 129, 
"Disclosure of Information About Capital Structure." In 1996, the corporation 
adopted SFAS 123, "Accounting for Stock-Based Compensation," under which the 
corporation elected to continue following Accounting Principles Board (APB) 
Opinion 25. In 1995, the corporation adopted SFAS 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
the effect of which was not material. 

Foreign Currency Translation  o  Unrealized gains and losses resulting from 
translating foreign subsidiaries' assets and liabilities into U.S. dollars 
generally are accumulated in an equity account on the balance sheet until such 
time as the subsidiary is sold or substantially or completely liquidated. 
Translation gains and losses relating to operations located in Latin American 
countries, where hyperinflation exists, and to international operations using 
the U.S. dollar as their functional currency are included in the income 
statement.

                                    - 25 -




Financial Instruments  o  Financial instruments are used to hedge financial 
risk caused by fluctuating interest and currency rates. The amounts to be paid 
or received on interest rate risk instruments that hedge debt, accrue and are 
recognized over the lives of the instruments. Gains and losses on foreign 
currency risk instruments used to hedge firm commitments are deferred and 
recognized as part of the related foreign currency transactions.
  Foreign currency instruments that are designated to offset fluctuations in 
the dollar value of foreign currency accounts receivable and payable and from 
earnings fluctuations in anticipated foreign currency cash flows are marked to 
market and the results recognized immediately as other income or other 
expense.

Cash Equivalents  o  The corporation considers as cash equivalents all highly 
liquid investments that are readily convertible to known amounts of cash and 
are so near their maturity that they present insignificant risk of changes in 
value because of changes in interest rates.

Inventories  o  Inventories are stated at cost or market, whichever is lower. 
These amounts do not include depreciation and amortization, the impact of 
which is not significant to the financial statements.
  Approximately 67 percent of inventory amounts before application of the LIFO 
method at Dec. 31, 1997 (66 percent at Dec. 31, 1996) have been valued on the 
LIFO basis; the "average cost" method is used for the balance. It is estimated 
that if inventories had been valued at current costs, they would have been 
approximately $348 million and $329 million higher than reported at Dec. 31, 
1997 and 1996, respectively. 

Fixed Assets  o  Fixed assets are carried at cost. Expenditures for 
replacements are capitalized, and the replaced items are retired. Gains and 
losses from the sale of property are included in income.
  Depreciation is calculated on a straight-line basis. The corporation and its 
subsidiaries generally use accelerated depreciation methods for tax purposes 
where appropriate.

Patents, Trademarks and Goodwill  o  Amounts paid for purchased patents and 
newly acquired businesses in excess of the fair value of the net assets of 
such businesses have been charged to patents, trademarks and goodwill. The 
portion of such amounts determined to be attributable to patents is amortized 
over their remaining lives, while trademarks and goodwill are amortized over 
the estimated period of benefit, generally 5 to 20 years.

Research and Development  o  Research and development costs are charged to 
expense as incurred. Depreciation expense applicable to research and 
development facilities and equipment is included in Depreciation and 
amortization in the Consolidated Statement of Income ($12 million in 1997, $11 
million in 1996 and $14 million in 1995).

Income Taxes  o  Provisions have been made for deferred income taxes based on 
differences between financial statement and tax bases of assets and 
liabilities using currently enacted tax rates and regulations. 

Environmental Costs  o  Environmental expenditures are expensed or capitalized 
as appropriate, depending on their future economic benefit. Expenditures 
relating to an existing condition caused by past operations and having no 
future economic benefits are expensed. Environmental expenditures include site 
investigation, physical remediation, operation and maintenance, and legal and 
administrative costs. Environmental accruals are established for sites where 
it is probable that a loss has been incurred and the amount of the loss can 
reasonably be estimated. Where the estimate is a range and no amount within 
the range is a better estimate than any other amount, the corporation accrues 
the minimum amount in the range and includes the balance of the range in its 
reported contingencies.

Retirement Programs  o  The cost of pension benefits under the U.S. Retirement 
Program is determined by an independent actuarial firm using the projected 
unit credit actuarial cost method, with an unrecognized net asset at Jan. 1, 
1986, amortized over 15 years. Contributions to this program are made in 
accordance with the regulations of the Employee Retirement Income Security Act 
of 1974.
  The cost of postretirement benefits is recognized on the accrual basis over 
the period in which employees become eligible for benefits. 

Incentive Plans  o  The corporation applies APB Opinion 25 in accounting for 
the stock purchase plan and the stock option portion of its employee 
compensation plan. Compensation expense is recognized for other stock-based 
incentives issued under the long-term incentive plan.

Reclassifications  o  Certain prior year amounts have been reclassified to 
conform with the current year's presentation.

Fair values of financial instruments are estimated by using a method that 
indicates the amount at which the instrument could be exchanged in a current 
transaction between willing parties, other than in a forced or liquidation 
sale. The fair values of the financial instruments included on the 
Consolidated Balance Sheet were estimated as follows: 

Cash, Short-Term Receivables and Accounts Payable  o  At Dec. 31, 1997 and 
1996, the carrying amounts approximate fair values because of the short 
maturity of these instruments. The corporation did not 

                                    - 26 -




have any foreign currency forward contracts outstanding at Dec. 31, 1997 ($38 
million at Dec. 31, 1996) to hedge fluctuations in the dollar value of short-
term foreign currency receivables and payables.
  Outstanding foreign currency forward contracts and options used as a means 
of offsetting fluctuations in the dollar value of other foreign currency 
accounts receivable and payable and earnings fluctuations from anticipated 
foreign currency cash flows totaled $185 million at Dec. 31, 1997 ($188 
million at Dec. 31, 1996). During 1997 and 1996, the average fair values of, 
and the resultant gains and losses associated with, these contracts were not 
material.

Investments  o  The corporation's investments in equity companies, 
partnerships and other businesses generally involve joint ventures for which 
it is not practicable to determine fair values. 

Long-Term Receivables  o  The fair values of long-term receivables are 
calculated using current interest rates and consideration of underlying 
collateral where appropriate. The fair value, which approximate the carrying 
values of $85 million and $51 million, are included in Other assets in the 
Consolidated Balance Sheet at Dec. 31, 1997 and 1996, respectively. 

Debt  o  The corporation uses various types of financial instruments, 
including interest rate swaps and forward rate agreements, to manage exposure 
to financial market risk caused by interest rate fluctuations. An interest 
rate swap held at Dec. 31, 1997 and 1996, had a nominal carrying amount and 
fair value.

Carrying and Fair Values  o  The carrying values and fair values of the 
corporation's investments, long-term receivables and debt financial 
instruments at Dec. 31, 1997 and 1996, are summarized in the table below. Fair 
values are based on quoted market values, where available, or discounted cash 
flows (principally long-term debt).

  In February 1996, the corporation purchased 95 percent of the outstanding 
shares of Companhia Alcoolquimica Nacional, a Brazilian producer of vinyl 
acetate monomer. 
  In July 1995, the corporation and two Kuwaiti corporations, Petrochemical 
Industries Company and Boubyan Petrochemical Company, formed EQUATE 
Petrochemical Company, a joint venture for development of a world-scale 
petrochemical complex in Kuwait. EQUATE commenced operations in 1997. 
  In March 1995, the corporation acquired 50 percent of the equity of Polimeri 
Europa S.r.l., a producer of ethylene and polyethylene resins, from EniChem 
S.p.A. for $216 million. EniChem retained the other 50 percent. 
  In February 1995, the corporation purchased certain ethylene oxide 
derivative businesses from Imperial Chemical Industries of London for $71 
million.
  In January 1995, the corporation and Mitsubishi Corporation concluded the 
sale of newly issued common stock of UCAR International Inc. to a new company 
formed by Blackstone Capital Partners II Merchant Banking Fund L.P. and a 
repurchase of certain shares by UCAR that resulted in Blackstone acquiring a 
75 percent interest in UCAR. The corporation received $343 million in net cash 
proceeds and retained a 25 percent equity interest in UCAR. This transaction 
resulted in a gain of $220 million ($154 million after-tax). In August 1995, 
the corporation joined in UCAR's initial public offering to sell its remaining 
equity interest in UCAR for net cash proceeds of $199 million. This sale 
resulted in a gain of $161 million ($99 million after-tax).

a) Holders may request redemption of these debentures from the corporation on 
   June 1, 2005.
b) Redeemable at the option of the corporation on or after Aug. 1, 2002.

  The corporation has a credit agreement with a group of banks providing the 
corporation with $1 billion in credit through January 2002, but with the 
option, subject to certain conditions, to increase the available credit by 
$250 million and to extend the maturity date of the agreement by one year on a 
rolling basis. Several options are available to borrow at floating interest 
rates based on LIBOR (London Interbank Offered Rate) or Certificate of Deposit 
Rate on a revolving basis.
  In 1997, the corporation established a medium-term note program that allows 
for borrowings of up to $500 million. Notes issued under the program will have 
a maturity of nine months or longer and will bear interest at either a fixed 
or floating rate determined by reference to interest rate formulas. 
  At Dec. 31, 1997, there were no outstanding borrowings under either the 
corporation's credit agreement or its medium-term note program. 
  In 1996, the corporation issued $200 million of 7.75 percent debentures 
maturing in 2096. The maturity of the debentures may be shortened under 
certain circumstances to preserve the deductibility of interest payments for 
Federal income tax purposes.
  The corporation's credit agreement and the indentures under which notes and 
debentures are issued contain covenants normal for these types of instruments. 
These covenants place certain limits on the corporation's ability to merge 
with another entity, sell assets, engage in sale-leaseback transactions, incur 
debt or create liens on assets. In addition, the credit agreement requires the 
corporation to meet leverage and interest coverage tests.
  Pollution control and other facility obligations represent state, 
commonwealth and local governmental bond financing of pollution control and 
other facilities, and are treated for accounting and tax purposes as debt of 
the corporation. These tax-exempt obligations mature at various dates from 
1998 through 2023 and had an average annual effective interest rate of 7.2 
percent in 1997.
  The weighted average and effective interest rates in 1997 on the 
corporation's fixed-rate debt, other than pollution control and other facility 
obligations, were 7.7 percent. The corporation's weighted average interest 
rate on short-term borrowings outstanding as of Dec. 31, 1997 was 6.4 percent 
(6.3 percent at Dec. 31, 1996).
  Payments due on long-term debt in the four years following 1998 are: 1999, 
$182 million; 2000, $21 million; 2001, $23 million, and 2002, $16 million.

Minority Interest
  In January 1997, a newly formed real estate investment trust subsidiary 
issued $250 million of preferred stock bearing a current dividend yield of 14 
percent for 10 years and 1 percent thereafter. In October 1997, the preferred 
shares were redeemed for $240 million.

TWELVE
Retirement Programs

Pension Benefits  o  The noncontributory defined benefit retirement program of 
Union Carbide Corporation ("U.S. Retirement Program") covers substantially all 
U.S. employees and certain employees in other countries. Pension benefits are 
based primarily on years of service and compensation levels prior to 
retirement. Pension coverage for employees of the corporation's non-U.S. 
consolidated subsidiaries is provided through separate plans, to the extent 
deemed appropriate. Obligations under such plans are principally provided for 
by depositing funds with trustees.

  The components of net periodic pension cost for the plans combined are as 
follows:

Millions of dollars

  Pension obligations are valued using the 1994 Uninsured Pensioner Mortality 
Table. Prior to 1997, these obligations were valued using the 1983 Group 
Annuity Mortality Table. The actuarial assumptions used were as 
follows:

At December 31,                                  1997      1996

Postretirement Benefits Other Than Pensions  o  The corporation provides 
health care and life insurance benefits for eligible retired employees and 
their eligible dependents. These benefits are provided through various 
insurance companies and health care providers.
  The obligation is determined by application of the terms of health and life 
insurance plans, together with relevant actuarial assumptions and health care 
cost trends projected to increase annually at rates of 8.0 percent in 1998 and 
7.5 percent in 1999, falling incrementally to a 5.0 percent annual increase in 
2004 and thereafter.
  The effect of a 1 percent annual increase in the assumed health care cost 
trend rates would increase the accumulated postretirement benefit obligation 
at Dec. 31, 1997 by $33 million, and the aggregate of service and interest 
cost components of net periodic postretirement benefit costs by $4 million. 
Measurement of the accumulated postretirement benefit obligation was based on 
the same actuarial assumptions used in the pension calculations.
  The corporation has funded postretirement benefits for certain retirees who 
retired prior to Dec. 31, 1988. The funds are invested primarily in common 
stocks.
  The components of net periodic postretirement benefit cost are as follows:

Millions of dollars

  Benefit Obligations                            $498      $506

  The accumulated postretirement benefit obligation for retirees is net of 
$131 million at Dec. 31, 1997 ($130 million at Dec. 31, 1996), which is 
reimbursed to the corporation in part by previously owned businesses under 
ongoing benefit-sharing agreements.

Deferred Compensation Plan  o  Since Jan. 1, 1995, the corporation has 
provided an unfunded, nonqualified deferred compensation plan to certain key 
employees, offering them an election to defer a portion of their gross pay. 
The corporation's obligation to employees is adjusted to reflect changes in 
the market values of employees' investment choices. With limited exceptions, 
participants' deferred account balances are scheduled for payment at or after 
full retirement.

Postemployment Benefits  o  During 1995 the corporation recorded a charge of 
$68 million ($49 million after-tax) for postemployment benefits. The charge 
included severance costs relating to future staff reductions associated with 
work process simplification efforts and changes in the corporation's severance 
benefits.

THIRTEEN
Employee Stock Ownership Plan

  The Union Carbide Corporation Employee Stock Ownership Plan (ESOP) is an 
integral part of the Savings and Investment Program (the Program) for 
employees. Prior to October 1997, each share of the corporation's preferred 
stock held by the ESOP (ESOP shares) was convertible into and had the same 
voting rights as one share of the corporation's common stock. The annual 
preferred dividend was $0.794 per share. In October 1997 the trustee of the 
ESOP exercised its right to convert all outstanding ESOP shares into the 
corporation's common stock. As a result of the conversion, the corporation's 
common stock outstanding at that date was increased by 15.4 million shares.
  Substantially all full-time employees in the U.S. are eligible to 
participate in the ESOP through the allocation of ESOP shares equivalent to 
the corporation's matching contribution of 75 percent of eligible employee 
contributions to the Program. In addition, in 1997, eligible employees 
received the equivalent of up to twenty days pay in ESOP shares through the 
corporation's ESOP profit sharing plan. 
  Common shares held by the ESOP generally are sold in the open market when 
employees make withdrawals or sell ESOP shares within their account. 
  The cost of the ESOP is recognized as incurred and was $7 million in 1997 
($2 million and $4 million in 1996 and 1995, respectively). The increase in 
1997 costs was principally due to the allocation of more shares to 
participants through the corporation's ESOP profit sharing plan. Continued 
reductions in ESOP costs are due primarily to appreciation in the 
corporation's common stock. At Dec. 31, 1997, 15.4 million common shares held 
by the ESOP were outstanding, 6.5 million of which were allocated to 
employees' accounts.  During 1997, 1.3 million ESOP shares were allocated to 
employees' accounts. 


FOURTEEN
Incentive Plans

  On April 27, 1997, stockholders approved the 1997 Union Carbide Long-Term 
Incentive Plan for key employees. The Plan provides for granting incentive and 
nonqualified stock options; exercise payment rights; grants of stock, 
including restricted stock, and performance awards. Holders of options may be 
granted the right to receive payments of amounts equal to the regular cash 
dividends paid to holders of the corporation's common stock during the period 
an option is outstanding. The number of shares granted or subject to options 
generally cannot exceed 2 million under the Plan. However, up to 4 million 
additional shares may be granted or subject to options to the extent the 
corporation acquires shares after April 27, 1997. Option prices are equal to 
the closing price of the corporation's common stock on the date of the grant, 
as listed on the New York Stock Exchange Composite Transactions. Options 
generally become exercisable two years after such date. Options may not have a 
duration of more than ten years. The option price may be settled in cash, 
common shares of the corporation currently owned by a participant, withholding 
stock shares from the exercise or a combination of these alternatives. 
Restricted stock award shares are entitled to vote and dividends are credited 
to the holder's account, but these shares are generally nontransferable for 
varying periods after the grant date. Once the vesting conditions are met, the 
shares become fully transferable. Performance awards may be paid in common 
stock, cash or other forms of property. No dividend-equivalent payment rights 
or performance awards were granted in 1997. 
  No awards were made in 1997, and no further awards can be made, under 
previous plans. Prior plans still have options outstanding and restricted 
stock not yet vested, whose terms are generally similar to nonqualified stock 
options and restricted stock grants under the 1997 plan.

during 1995). 
  The following table summarizes information about fixed price option shares

  Had compensation cost related to the fixed price options been recorded at 
fair value on the dates of grant in accordance with SFAS 123, the effect on 
the corporation's net income and EPS amounts would have been as follows:

  The Black-Scholes Option Pricing Model was used to estimate the fair values 
of options granted during 1997, 1996 and 1995. The assumptions used for these 
grants included a 6-year average expected life for all years, and zero-coupon 
U.S. government risk free interest rates of 5.92%, 5.95%, and 5.70%, current 
dividend yields of 1.73%, 1.78%, and 1.75%, and volatility of 28.77%, 28.00%, 
and 28.78% for the years ended 1997, 1996 and 1995, respectively. The weighted 
average fair values of options granted during the years 1997, 1996, and 1995 
were $15.54, $15.31 and $13.43, respectively.
  On Sept. 24, 1997, the board approved the 1997 Union Carbide Corporation EPS 
Incentive Plan for a limited number of senior managers. It is designed to 
grant awards if the corporation achieves $4.00 or more diluted earnings per 
share performance during 1999 and 2000. The plan requires these senior 
managers to put an amount equivalent to a portion of their annual base pay at 
risk, up to 100 percent, should diluted earnings per share not equal or exceed 
$4.00 in the year 2000. The amount at risk will be deducted from compensation 
over three years and is converted to units equivalent to common stock using a 
$47.75 share price, the closing price of the corporation's common stock on the 
date the plan was approved by the board of directors. Participants could be 
awarded up to four times the number of units at risk for each of the years 
1999 and 2000, depending on the extent to which the goals of the plan are 
exceeded. Participants will also be credited with dividend-equivalents in the 
form of additional units. Payments under the plan will be in cash and are 
scheduled for 2002, 2003 and 2004. Failure to meet the requirements of the 
plan will result in forfeiture of the amounts at risk.

FIFTEEN
Stockholders' Equity
  Subject to the following discussion, each outstanding share of common stock 
has identical rights in voting on corporate matters, dividends when declared, 
liquidation and other corporate matters.
  Each outstanding share of common stock bears one Right entitling its holder, 
under certain circumstances, to buy a share of common stock at a purchase 
price of $37.67 (subject to adjustment). The Rights may not be exercised until 
10 days after a person or group acquires 20 percent or more of UCC's common 
stock, or until a date determined by the board of directors following 
announcement of a tender offer that, if consummated, would result in 20 
percent or more ownership of the common stock. Until then, separate Rights 
certificates will not be issued, nor will the Rights be traded separately from 
the stock.
  Should an acquirer become the beneficial owner of 20 percent of the common 
stock, and under certain additional circumstances, the corporation's 
stockholders (other than the acquirer) would have the right to buy common 
stock in Union Carbide Corporation, or in the surviving enterprise if the 
corporation is acquired, having a value equal to two times the purchase price 
of the Right then in effect.
  The Rights will expire on Aug. 31, 1999, unless redeemed prior to that date. 
The redemption price is $0.01 per Right.
  On July 23, 1997, the board of directors of the corporation increased the 
number of shares that may be repurchased under the existing common stock 
repurchase program to 60 million shares. 
  Through Dec. 31, 1997, the corporation had repurchased 49.3 million shares 
since inception of the program in 1993 (7.0 million during 1997) at an average 
effective price of $34.69 per share. The corporation will continue to acquire 
additional shares from time to time at prevailing market prices, at a rate 
consistent with the combination of corporate cash flow and market conditions.
  In conjunction with the corporation's common stock buyback program, put 
options were sold in a series of private placements entitling the holders to 
sell 12.9 million shares of common stock to UCC at specified prices upon 
exercise of the options. Since inception of this program through Dec. 31, 
1997, options representing 9.8 million common shares have expired unexercised, 
while options representing 3.1 million shares were exercised for $129 million, 
or an average price of $40.94 per share. No options were outstanding at Dec. 
31, 1997. Premiums received since inception of the program, which are recorded 
as Additional paid-in capital, have reduced the average price of repurchased

Leases
  Leases that meet the criteria for capitalization have been classified and 
accounted for as capital leases. For operating leases, primarily involving 
facilities and distribution equipment, the future minimum rental payments 
under leases with remaining noncancelable terms in excess of one year are:

Millions of dollars,
year ending December 31,
1998                             $ 62
1999                               58
2000                               53
2001                               50
2002                               58
Subsequent to 2002                186
Total minimum payments            467
Future sublease rentals            81
Net Minimum Rental Commitments   $386

  The present value of the net minimum rental payments amounts to $303 
million, of which $214 million pertains to the corporation's headquarters 
lease. Total lease and rental payments (net of sublease rental of $21 million 
in 1997 and $20 million in 1996 and 1995) were $54 million, $53 million and 
$67 million for 1997, 1996 and 1995, respectively. 
  During 1995 the corporation recognized a nonrecurring, noncash charge of 
$191 million ($134 million after-tax) for future minimum lease payments on 
unused office space, primarily at the corporation's headquarters. The 
headquarters charge reflects the pro rata costs of unused office space over 
the remaining term of the lease, which runs to 2006, less anticipated net 
sublease income. Neither the expected future costs nor expected net sublease 
revenues were discounted.

SEVENTEEN
Commitments and Contingencies

Purchase Agreements  o  The corporation has three major agreements for the 
purchase of ethylene-related products and two other purchase agreements in the 
U.S. and Canada. Total purchases under these agreements were $245 million, 
$233 million and $251 million in 1997, 1996 and 1995, respectively. The net 
present value of the fixed and determinable portion of obligations under these 
purchase commitments at Dec. 31, 1997 (at current exchange rates, where 
applicable) is presented in the following table.

Millions of dollars,
year ending December 31,
1998                             $ 69
1999                               60
2000                               31
2001                               23
2002                               20
2003 to expiration of contracts    88
Total                            $291

Environmental  o  The corporation is subject to loss contingencies resulting 
from environmental laws and regulations, which include obligations to remove 
or remediate the effects on the environment of the disposal or release of 
certain wastes and substances at various sites. The corporation has 
established accruals in current dollars for those hazardous waste sites where 
it is probable that a loss has been incurred and the amount of the loss can 
reasonably be estimated. The reliability and precision of the loss estimates 
are affected by numerous factors, such as different stages of site evaluation, 
the allocation of responsibility among potentially responsible parties and the 
assertion of additional claims. The corporation adjusts its accruals as new 
remediation requirements are defined, as information becomes available 
permitting reasonable estimates to be made, and to reflect new and changing 
facts.
  At Dec. 31, 1997, the corporation had established environmental remediation 
accruals in the amount of $264 million ($310 million in 1996). These accruals 
have two components, estimated future expenditures for site investigation and 
cleanup and estimated future expenditures for closure and postclosure 
activities. In addition, the corporation had environmental loss contingencies 
of $159 million at Dec. 31, 1997.
  The corporation has sole responsibility for the remediation of approximately 
36 percent of its environmental sites for which accruals have been 
established. These sites are well advanced in the investigation and cleanup 
stage. The corporation's environmental accruals at Dec. 31, 1997, included 
$197 million for these sites ($222 million at Dec. 31, 1996), of which $79 
million ($92 million at Dec. 31, 1996) was for estimated future expenditures 
for site investigation and cleanup and $118 million ($130 million at Dec. 31, 
1996) was for estimated future expenditures for closure and postclosure 
activities. In addition, $87 million of the corporation's environmental loss 
contingencies at Dec. 31, 1997, related to these sites. The site with the 
largest total potential cost to the corporation is a nonoperating site. Of the 
above accruals, this site accounted for $31 million ($32 million at Dec. 31, 
1996), of which $17 million ($18 million at Dec. 31, 1996) was for estimated 
future expenditures for site investigation and cleanup and $14 million ($14 
million at Dec. 31, 1996) was for estimated future expenditures for closure 
and postclosure activities. In addition, $20 million of the above 
environmental loss contingencies related to this site.
  The corporation does not have sole responsibility at the remainder of its 
environmental sites for which accruals have been established. All of these 
sites are in the investigation and cleanup stage. The corporation's 
environmental accruals at Dec. 31, 1997, included $67 million for estimated 
future expenditures for site investigation and cleanup at these sites ($88 
million at Dec. 31, 1996). In addition, $72 million of the corporation's 
environmental loss contingencies related to these sites. The largest two of 
these sites are also nonoperating sites. Of the above accruals, these sites 
accounted for $29 million ($37 million at Dec. 31, 1996) for estimated future 
expenditures for site investigation and cleanup. In addition, $20 million of 
the above environmental loss contingencies related to these sites.
  Worldwide expenses related to environmental protection for compliance with 
Federal, state and local laws regulating solid and hazardous wastes and 
discharge of materials to air and water, as well as for waste site remedial 
activities, totaled $100 million in 1997, $110 million in 1996 and $138 
million in 1995. 

                                    - 39 -





Other  o  The corporation has severally guaranteed 45 percent (approximately 
$606 million at Dec. 31, 1997) of EQUATE Petrochemical Company's debt and 
working capital financing needs until certain completion and financial tests 
are achieved. If these tests are met, a $54 million several guarantee will 
provide ongoing support thereafter. The corporation also severally guaranteed 
certain sales volume targets until EQUATE's sales capabilities are proved. In 
addition, the corporation has pledged its shares in EQUATE as security for 
EQUATE's debt. The corporation has political risk insurance coverage for its 
equity investment and, through Sept. 30, 1998, substantially all of its 
several guarantee of EQUATE's debt.
  The corporation and its consolidated subsidiaries had additional contingent 
obligations at Dec. 31, 1997, totaling $63 million, of which $31 million 
related to guarantees of debt.

Litigation  o  The corporation is one of a number of defendants named in 
approximately 4,900 lawsuits in both Federal and state courts, some of which 
have more than one plaintiff, involving silicone breast implants. The 
corporation was not a manufacturer of breast implants but did supply generic 
bulk silicone materials to certain manufacturers. Also, the corporation in 
1990 acquired and in 1992 divested the stock of a small specialty silicones 
company that, among other things, supplied silicone gel intermediates and 
silicone dispersions for breast implants. In 1993 most of the suits that were 
brought in Federal courts were consolidated for pretrial purposes in the 
United States District Court, Northern District of Alabama.
  In 1995, the District Court approved a settlement program proposed by 
certain defendants, including the corporation. In August 1997, the court ruled 
that all claims based solely on the supply of generic bulk silicone materials 
should be dismissed against the corporation. That decision is final with 
respect to cases in Federal courts, but does not affect the corporation's 
participation in the settlement program. Based on the corporation's 
understanding of the number of claims that were properly filed under the 
settlement, the corporation estimates that its maximum expenditures under the 
program should not exceed $100 million prior to insurance recovery. Although 
insurance coverage is subject to issues as to scope and application of 
policies, retention limits, exclusions and policy limits, and the insurers 
have reserved their right to deny coverage, the corporation believes that 
after probable insurance recoveries neither the settlement nor litigation 
outside the settlement will have a material adverse effect on the consolidated 
financial position of the corporation.
  In addition to the above, the corporation and its consolidated subsidiaries 
are involved in a number of legal proceedings and claims with both private and 
governmental parties. These cover a wide range of matters, including, but not 
limited to, product liability; trade regulation; governmental regulatory 
proceedings; health, safety and environmental matters; employment; patents; 
contracts, and taxes. In some of these legal proceedings and claims, the cost 
of remedies that may be sought or damages claimed is substantial.  
  The corporation has recorded nonenvironmental litigation accruals of $184 
million, and related insurance recovery receivables of $147 million. At Dec. 
31, 1997, the corporation had nonenvironmental litigation loss contingencies 
of $57 million.
  While it is impossible at this time to determine with certainty the ultimate 
outcome of any legal proceedings and claims referred to in this note, 
management believes that adequate provisions have been made for probable 
losses with respect thereto and that such ultimate outcome, after provisions 
therefor, will not have a material adverse effect on the consolidated 
financial position of the corporation, but could have a material effect on 
consolidated results of operations in a given quarter or year. Should any 
losses be sustained in connection with any of such legal proceedings and 
claims in excess of provisions therefor, they will be charged to income in the 
future.

Management's Statement of Responsibility for Financial Statements
  Union Carbide Corporation's financial statements are prepared by management, 
which is responsible for their fairness, integrity and objectivity. The 
accompanying financial statements have been prepared in conformity with 
generally accepted accounting principles and, accordingly, include amounts 
that are estimates and judgments. All historical financial information in this 
annual report is consistent with the accompanying financial statements.
  The corporation maintains accounting systems, including internal accounting 
controls monitored by a staff of internal auditors, that are designed to 
provide reasonable assurance of the reliability of financial records and the 
protection of assets. The concept of reasonable assurance is based on 
recognition that the cost of a system must not exceed the related benefits. 
The effectiveness of those systems depends primarily upon the careful 
selection of financial and other managers, clear delegation of authority and 
assignment of accountability, inculcation of high business ethics and 
conflict-of-interest standards, policies and procedures for coordinating the 
management of corporate resources and the leadership and commitment of top 
management.
  The corporation's financial statements are audited by KPMG Peat Marwick LLP, 
independent certified public accountants, in accordance with generally 
accepted auditing standards. These standards provide for the auditors to 
consider the corporation's internal control structure to the extent they deem 
necessary in order to issue their opinion on the financial statements.
  The Audit Committee of the board of directors, which consists solely of 
nonemployee directors, is responsible for overseeing the functioning of the 
accounting system and related controls and the preparation of annual financial 
statements. The Audit Committee recommends to the board of directors the 
selection of the independent auditors, which is submitted to the stockholders 
for ratification. The Audit Committee periodically meets with the independent 
auditors, management and internal auditors to review and evaluate their 
accounting, auditing and financial reporting activities and responsibilities. 
The independent and internal auditors have full and free access to the Audit 
Committee and meet with the committee, with and without management present.

Independent Auditors' Report
To the Stockholders and Board of Directors of 
Union Carbide Corporation:
  We have audited the accompanying consolidated balance sheet of Union Carbide 
Corporation and subsidiaries as of Dec. 31, 1997 and 1996, and the related 
consolidated statements of income, stockholders' equity, and cash flows for 
each of the years in the three-year period ended Dec. 31, 1997. These 
consolidated financial statements are the responsibility of the company's 
management. Our responsibility is to express an opinion on these consolidated 
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, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of Union 
Carbide Corporation and subsidiaries at Dec. 31, 1997 and 1996, and the 
results of their operations and their cash flows for each of the years in the 
three-year period ended Dec. 31, 1997, in conformity with generally accepted 
accounting principles.
