                   UNION CARBIDE REPORTS 4th QUARTER LOSS


     DANBURY, Conn., Jan. 29 -- Union Carbide Corporation (UCC) today reported
a fourth quarter 2000 loss of $0.70 per diluted share, including a non-
recurring charge of $0.17 per diluted share related to the company's UOP
partnership, compared with earnings of $0.22 per diluted share in the third
quarter of 2000 and $0.68 per diluted share for fourth quarter 1999.

     UCC Chairman and CEO William H. Joyce said that margins and earnings were
adversely affected by high raw material and energy costs, which rose to
unprecedented levels by the end of the quarter, and by average selling prices,
which were lower than in the prior quarter.  The negative impact on earnings
was primarily in the North American-based Basic Chemicals and Polymers
businesses.  Dr. Joyce also noted that sales revenues declined somewhat from
the prior quarter, while sales volumes were virtually unchanged.

      "Carbide and others are being negatively impacted by a volatile energy
market," said Dr. Joyce.  "At the same time, product selling prices have not
been keeping pace with the high cost of natural gas and natural gas liquids,
such as ethane and propane, which are the primary feedstocks for our olefins-
chain derivatives."

     He noted, for example, that natural gas prices more than quadrupled from
December 1999 to the end of December 2000, while the price for ethane nearly
doubled and the cost of propane increased nearly 40 percent in the same
period.

     "To improve margins and reduce losses in this very challenging
environment," Dr. Joyce said, "the company is implementing price increases for
many severely affected products and cutting back production of some products.
UCC has temporarily shut down units in cases where adequate price increases
are not being realized."  The company also has intensified efforts to control
fixed costs and capital expenditures, and to improve working capital
management.

     Income from corporate investments carried at equity totaled $8 million
for the current quarter, compared with $40 million in the fourth quarter of
last year and $33 million in third

quarter 2000.  Excluding the non-recurring charge of $31 million from UOP,
partnership losses totaled $15 million in the fourth quarter 2000, compared to
a loss of $9 million in the same period last year and a loss of $6 million in
the third quarter 2000.

     Union Carbide recorded a net loss for the quarter of $94 million,
compared to net income of $94 million for last year's fourth quarter and net
income of $29 million for the third quarter of this year.  Fourth quarter 2000
sales totaled $1.598 billion compared with $1.552 billion for the fourth
quarter of 1999 and $1.637 billion for third quarter 2000.  The effective tax
rate for the quarter was approximately 25 percent.

     Carbide's S&I segment reported an operating profit of $51 million for the
fourth quarter of 2000, compared with $77 million for the same period last
year, and $45 million for the third quarter of this year. S&I segment results
were negatively affected by reduced partnership income.

     The BC&P segment reported an operating loss of $122 million for the
fourth quarter of 2000, compared to operating income of $61 million in the
fourth quarter of 1999, and an operating loss of $15 million in the prior
quarter.

                            Full Year Results

     For the full year 2000, UCC reported net income of $162 million, or $1.18
per diluted share.  In addition to the non-recurring charge of $0.17 per
diluted share related to UOP, full-year results included a gain of $0.08 per
diluted share from the receipt and sale of shares issued in connection with
the demutualization of Metropolitan Life Insurance Company, a provider of
certain employee benefits for the company, and $0.40 per diluted share from
amortization of investment gains and changes in actuarial assumptions
reflecting long-term investment returns on pension plan assets.  Prior year
income was $311 million, or $2.27 per diluted share, before a charge of $0.14
per diluted share from the cumulative effect of a change in accounting
principle.  UCC set a company record in 2000 with worldwide sales of $6.526
billion, compared with the previous record of $6.502 billion set in 1997.
Worldwide sales in 1999 were $5.870 billion.
