                                CABOT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                December 31, 2000
                                    UNAUDITED

A.   BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of Cabot
     Corporation and majority-owned and controlled U.S. and non-U.S.
     subsidiaries ("Cabot"). Investments in 20 to 50 percent owned affiliates
     are accounted for on the equity method. Intercompany transactions have been
     eliminated.

     The unaudited consolidated financial statements have been prepared in
     accordance with the requirements of Form 10-Q and consequently do not
     include all disclosures required by Form 10-K. Additional information may
     be obtained by referring to Cabot's Form 10-K for the year ended September
     30, 2000.

     The financial information submitted herewith is unaudited and reflects all
     adjustments which are, in the opinion of management, necessary to provide a
     fair statement of the results for the interim periods ended December 31,
     2000 and 1999. All such adjustments are of a normal recurring nature. The
     results for interim periods are not necessarily indicative of the results
     to be expected for the fiscal year.

B.   SPECIAL ITEMS AND BUSINESS DEVELOPMENTS

     During fiscal 2000, Cabot approved plans to close several plants. In
     relation to the plant closings, Cabot recorded an $18 million charge.
     Included in the charge was an accrual of $2 million for severance and
     termination benefits for approximately 38 employees of the Chemical and
     Performance Materials Businesses and $7 million for facility closing costs,
     of which none was paid out in fiscal 2000 or the first quarter of fiscal
     2001. As of December 31, 2000, $9 million had been accrued, most of which
     will be expended in fiscal 2001. The remainder of the charge included $9
     million for the impairment of long-lived assets.

     During 1999, Cabot began implementation of initiatives to reduce costs and
     improve operating efficiencies. In connection with these efforts, Cabot
     recorded a $26 million charge for capacity utilization and cost reduction
     initiatives. These initiatives included $16 million for severance and
     termination benefits for approximately 265 employees, of which $15 million
     has been paid out as of December 31, 2000.

C.   DISCONTINUED OPERATIONS

     On September 19, 2000, Cabot completed a transaction to sell its liquefied
     natural gas (LNG) segment for approximately $688 million cash. The sale
     included Cabot's LNG terminal in Everett, Massachusetts, its LNG tanker,
     the Matthew, and its equity interest in the Atlantic LNG liquefaction plant
     in Trinidad. The gain on the sale of the LNG segment was approximately $309
     million, net of taxes of $178 million.

     On April 4, 2000, Cabot Microelectronics Corporation, then a subsidiary of
     Cabot, sold 4.6 million shares of its common stock in an initial public
     offering (IPO). The 4.6 million shares represented approximately 19.5% of
     Cabot Microelectronics. The net proceeds from the IPO were approximately
     $83 million. Cabot received an aggregate of approximately $81 million in
     dividends from Cabot Microelectronics. On July 25, 2000, a committee of
     Cabot's Board of Directors voted to spin off its remaining 80.5% equity
     interest in Cabot Microelectronics by distributing a special dividend of
     its remaining interest in Cabot Microelectronics to its common stockholders
     of record as of the close of regular trading on the New York Stock Exchange
     on September 13, 2000. The tax-free distribution took place on September
     29, 2000.

     Operating results for fiscal 2000 have been reclassified to present these
     businesses as discontinued operations.

D.   RECLASSIFICATION

     Certain amounts were reclassified in fiscal 2000 to reflect changes in
     Cabot's organization during the year and to conform to the fiscal 2001
     presentation.

E.   COMMITMENTS AND CONTINGENCIES

     Cabot is a defendant, or potentially responsible party, in various lawsuits
     and environmental proceedings wherein substantial amounts are claimed or at
     issue.

     As of December 31, 2000, Cabot has approximately $36 million reserved for
     environmental matters, primarily related to divested businesses. The amount
     represents Cabot's current best estimate of its share of costs likely to be
     incurred at those sites where costs are reasonably estimable based on its
     analysis of the extent of cleanup required, alternative cleanup methods
     available, abilities of other responsible parties to contribute, and its
     interpretation of applicable laws and regulations at each site. Cabot
     reviews the adequacy of this reserve as circumstances change at individual
     sites. Cabot is unable to reasonably estimate the amount of possible loss
     in excess of the accrued amount.

     In the opinion of Cabot, although final disposition of these suits and
     claims may impact Cabot's financial statements in a particular period, they
     will not, in the aggregate, have a material adverse effect on Cabot's
     financial position.

I.   FINANCIAL INFORMATION BY SEGMENT

     The framework for segment reporting is intended to give analysts and other
     financial statement users a view of Cabot "through the eyes of management".
     It designates Cabot's internal management reporting structure as the basis
     for determining Cabot's reportable segments, as well as the basis for
     determining the information to be disclosed for those segments. The
     following table provides financial information by segment for the three
     months ended December 31:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
                                December 31, 2000
                                    UNAUDITED

J.   RECENT ACCOUNTING DEVELOPMENTS

     In September 2000, the Emerging Issues Task Force ("EITF") reached a final
     consensus of Issue No. 00-10 "Accounting for Shipping and Handling Fees and
     Costs." Amounts billed as shipping and handling are required to be recorded
     as revenue, however it allows a company to adopt a policy of including
     shipping and handling costs in cost of sales. If shipping and handling
     costs are significant and are not included in cost of sales, a company
     should disclose both the amount of such costs and which line item on the
     income statement includes that amount. The Task Force also indicated that
     shipping and handling costs cannot be reported as a reduction in revenue.
     Cabot adopted EITF 00-10 as of October 1, 2000. Shipping and handling costs
     reclassified from Revenues to Cost of Goods Sold in fiscal 2000 to conform
     to the 2001 presentation amounted to $13 million.

     Effective October 1, 2000, Cabot adopted Statement of Financial Accounting
     Standards No. 133, "Accounting for Derivative Instruments and Hedging
     Activities" ("FAS 133"), as amended. FAS 133 establishes accounting and
     reporting standards requiring that all derivative instruments, including
     certain derivative instruments embedded in other contracts, be recorded in
     the balance sheet as either assets or liabilities measured at fair value.
     FAS 133 requires that changes in the derivative instrument's fair value be
     recognized currently in earnings, unless specific hedge accounting criteria
     are met. Special accounting for qualifying hedges allows a derivative
     instrument's gains and losses to offset related results on the hedged item
     in the income statement, and requires that a company must formally
     document, designate, and assess the effectiveness of transactions that
     receive hedge accounting. There are no derivative positions at December 31
     for which Cabot would seek to achieve hedge accounting or under this
     pronouncement. As such, the effect of adopting FAS 133 on Cabot's financial
     statements is not significant.

     In December 1999, the Securities and Exchange Commission ("SEC"), released
     Staff Accounting Bulletin No. 101 ("SAB 101"), which provides guidance on
     the recognition, presentation, and disclosure of revenue in financial
     statements filed with the SEC. In June 2000, the SEC released SAB 101B,
     which postponed the effective date of SAB 101 to the fourth quarter of
     fiscal years beginning after December 15, 1999. Cabot will be required to
     be in conformity with the provisions of SAB 101 in the fourth quarter of
     fiscal 2001. Cabot is currently evaluating the impact that SAB 101 will
     have on its financial condition and results of operations.

K.   DEBT

     In November 2000, a Cabot subsidiary borrowed 150 million EURO ($129
     million) from institutional lenders. The loan is payable in EUROs, bears
     interest at EURIBOR plus 1.10%, and matures in November 2003. Covenants of
     this debt agreement require Cabot to maintain certain financial ratios.

L.   TAXES

     In 2000, Cabot initiated a reorganization of its international legal entity
     structure. As a result of the reorganization, Cabot's overall effective
     income tax rate decreased from 36% for the quarter ended December 31, 1999
     to 29% for the quarter ended December 31, 2000.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


I. RESULTS OF OPERATIONS

Net sales and operating profit before taxes by segment are shown in Note I to
the Consolidated Financial Statements.

THREE MONTHS ENDED DECEMBER 31, 2000 VERSUS
THREE MONTHS ENDED DECEMBER 31, 1999

Net income from continuing operations for the first quarter of fiscal 2001 was
$28 million ($0.37 per diluted common share) compared to $31 million ($0.41 per
diluted common share) in the same quarter a year ago. Sales increased by $18
million from $377 million last year to $395 million this year due to strong
volumes and pricing. However, operating profit before taxes decreased 34% from
$59 million in the first quarter of fiscal 2000 to $39 million in the first
quarter of fiscal 2001. Increased feedstock costs in the Chemical Businesses and
higher raw material costs in the Performance Materials business were the primary
drivers behind the decrease in profitability.

Sales for the Chemical Businesses increased slightly to $334 million. Operating
profit decreased from $53 million to $41 million. The $12 million, or 23%,
decrease in profitability is primarily attributed to slower industrial growth in
North America, increased oil-based feedstock and natural gas costs and
unfavorable currency trends.

For the first quarter of fiscal 2001, carbon black volumes were able to keep
pace with the high volume levels achieved in the first quarter of fiscal 2000.
Overall, global carbon black volumes modestly decreased 2% this quarter versus
the first quarter of last year. Sales volumes increased 6% in both South America
and Europe though reduced economic growth in North America led to a 10% decrease
in volumes in that region. Similarly, Asia Pacific experienced a 7% decrease in
volumes. Carbon black was negatively impacted by increased oil-based feedstock
and natural gas costs. Feedstock costs were 21% higher in the first quarter of
this year versus the same quarter a year ago due to increases in oil prices. In
the past, changes in natural gas costs have not typically had a large impact on
the profitability of the carbon black business. However, natural gas costs were
54% higher in the first quarter of fiscal 2001 versus the same quarter in fiscal
2000 and therefore had a material negative impact on the business. The carbon
black business is still working to fully recover the lost margin resulting from
increases in its feedstock costs in previous quarters.

Fumed metal oxides sales were up slightly in the first quarter of fiscal 2001.
Improved mix and pricing offset slightly reduced volumes. Higher demand from the
electronics sector, principally Cabot Microelectronics Corporation, was offset
by lower demand from Cabot's traditional, silicone rubber customers. One time
costs associated with the start-up of the Midland, Michigan plant resulted in a
$2 million decrease in operating profit compared with last year's first quarter.
External factors such as foreign exchange and energy prices resulted in an
additional $1 million reduction in operating profit versus the prior year.

Cabot's inkjet colorants business continues to gain commercial acceptance of a
variety of products. Accordingly, the business reported $1 million in operating
profit in the first quarter of 2001.

Performance Materials sales were $56 million in the first quarter of fiscal 2001
compared with $51 million in fiscal 2000. While demand for tantalum capacitors
for the electronics and wireless telecommunications industries continues to
remain strong, sales volumes were 6% lower in the first quarter of 2001 than in
the same quarter a year ago. In addition, moderate price increases were not able
to fully offset substantial increases in tantalum ore costs resulting in an $11
million decline in operating profit. During the first quarter of fiscal 2001,
Cabot entered into new long-term contracts with its principal customers and an
additional contract with a key raw materials supplier. As a result of these
contracts, it is anticipated that Cabot's earnings in the tantalum business will
increase by approximately 50% in fiscal 2001, year over year. In fiscal 2002,
Cabot expects earnings from the tantalum business to increase by approximately
three times over fiscal 2001.

Specialty Fluids sales in the first quarter were $7 million versus $4 million
last year. Sales to date have been generated from the production and sale of
cesium formate as well as spodumene, tantalum and fine cesium chemicals.
Increased sales volumes and pricing resulted in a $3 million increase in
operating profit. During the first quarter, cesium formate was used in its first
drill-in application, a challenging high pressure, high temperature well in the
North Sea. The drill-in was successful in a number of dimensions including the
control of well pressure, the integrity of the drill hole, and the safety of
operating personnel. It is anticipated that the well's production rate will be
tested in the second quarter of 2001.

An increase in cash, principally due to the sales proceeds of the Liquefied
Natural Gas business ("LNG"), led to a $10 million increase in interest income
in the first quarter of this year.

Research and technical service spending was $11 million for the first quarter
versus $10 million for the first quarter of last year. Selling and
administrative expenses were $45 million for the first quarter of fiscal 2001, a
10% increase from $41 million spent last year. The increase is primarily
attributed to higher costs associated with an enterprise wide systems
initiative. Selling and administrative expenses and research and technical
service spending remained flat as a percentage of sales. They represented 11%
and 3%, respectively, of sales in both the current quarter and corresponding
quarter of fiscal 2000.

In 2000, Cabot initiated a reorganization of its international legal entity
structure. As a result of the reorganization, Cabot's overall effective income
tax rate decreased from 36% for the quarter ended December 31, 1999 to 29% for
the quarter ended December 31, 2000.

During 2000, Cabot approved plans to close several plants. In relation to plant
closings, Cabot recorded an $18 million charge. Included in the charge was an
accrual of $2 million for severance and termination benefits for approximately
38 employees of the Chemical and Performance Materials Businesses and $7 million
for facility closing costs, of which none was paid out in the first quarter of
fiscal 2001. As of December 31, 2000, $9 million is accrued, most of which will
be expended in fiscal 2001. The remainder of the charge included $9 million for
the impairment of long-lived assets. These actions will result in reduced
depreciation expense and certain other cost savings. These expenses were
included as special items in the Consolidated Statements of Income for the year
ended September 30, 2000.

During 1999, Cabot began implementation of initiatives to reduce costs and
improve operating efficiencies. In connection with these efforts, Cabot recorded
a $26 million charge for capacity utilization and cost reduction initiatives.
These initiatives included $16 million for severance and termination benefits
for approximately 265 employees, of which $15 million has been paid out as of
December 31, 2000.

II. CASH FLOW AND LIQUIDITY

During the first three months of the fiscal year, cash used in operating
activities totaled $214 million as compared to cash provided by operating
activities of $25 million for the same period last year. The uses of cash during
the first quarter of 2001 included a decrease in working capital and a tax
payment related to the September 2000 disposition of LNG.

Capital spending for the first three months of the year was $17 million. The
majority of capital spending related to maintaining existing assets. Cabot plans
to spend approximately $160 million in capital expenditures during the fiscal
year.

Cash provided by financing activities was $22 million in the first quarter of
fiscal 2001 as compared to $3 million for the same period last year. The key
components of net cash from financing activities were the issuance of a 3-year
EURO note for $129 million, the repayment of $63 million in long-term debt, and
the repurchase of $36 million of Common Stock.

In November 2000, a Cabot subsidiary borrowed 150 million EURO ($129 million)
from institutional lenders. The loan is payable in EUROs, bears interest at
EURIBOR plus 1.10%, and matures in November 2003.

On October 4, 2000, Cabot purchased $17 million of its Medium Term Notes at par
plus accrued interest. The 7.28% Medium Term Notes were issued on October 21,
1997 and were subject to a put at par in 2004.

On September 8, 2000, Cabot's Board of Directors authorized the repurchase of up
to 10 million shares of Cabot's Common Stock, superseding prior authorizations.
As of December 31, 2000, approximately 1.5 million shares have been purchased at
an average price of $23.50 per share under this new authorization.

As a result of the operating and financing activities during the quarter,
Cabot's ratio of total debt (including short-term debt net of cash) to capital
increased from negative 29% at September 30, 2000 to 4% at December 31, 2000.

Cabot maintains a credit agreement under which it may, under certain conditions,
borrow up to $300 million at floating rates. The facility is available through
January 3, 2002. As of December 31, 2000, Cabot had no borrowings outstanding
under this arrangement. Management expects cash on hand, cash from operations
and present financing arrangements, including Cabot's unused line of credit and
shelf registration for debt securities, to be sufficient to meet Cabot's cash
requirements for the foreseeable future.

III. RECENT ACCOUNTING DEVELOPMENTS

In September 2000, the Emerging Issues Task Force ("EITF") reached a final
consensus of Issue No. 00-10 "Accounting for Shipping and Handling Fees and
Costs." Amounts billed as shipping and handling are required to be recorded as
revenue, however it allows a company to adopt a policy of including shipping and
handling costs in cost of sales. If shipping and handling costs are significant
and are not included in cost of sales, a company should disclose both the amount
of such costs and which line item on the income statement includes that amount.
The Task Force also indicated that shipping and handling costs cannot be
reported as a reduction in revenue. Cabot adopted EITF 00-10 as of October 1,
2000. Shipping and handling costs reclassified in fiscal 2000 to conform to the
2001 presentation did not have a material impact on Cabot's consolidated
financial statements.

Effective October 1, 2000, Cabot adopted Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("FAS 133"), as amended. FAS 133 establishes accounting and
reporting standards requiring that all derivative instruments, including certain
derivative instruments embedded in other contracts, be recorded in the balance
sheet as either assets or liabilities measured at fair value. FAS 133 requires
that changes in the derivative instrument's fair value be recognized currently
in earnings, unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative instrument's gains and
losses to offset related results on the hedged item in the income statement, and
requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting. There are no
derivative positions at December 31 for which Cabot would seek to achieve hedge
accounting or under this pronouncement. As such, the effect of adopting FAS 133
on Cabot's financial statements is not significant.

In December 1999, the Securities and Exchange Commission ("SEC"), released Staff
Accounting Bulletin No. 101 ("SAB 101"), which provides guidance on the
recognition, presentation, and disclosure of revenue in financial statements
filed with the SEC. In June 2000, the SEC released SAB 101B, which postponed the
effective date of SAB 101 to the fourth quarter of fiscal years beginning after
December 15, 1999. Cabot will be required to be in conformity with the
provisions of SAB 101 in the fourth quarter of fiscal 2001. Cabot is currently
evaluating the impact that SAB 101 will have on its financial condition and
results of operations.
