                                CABOT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 2001
                                    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
       March 31, 2001 and 2000. 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 the quarter a $17 million charge was recorded, related to the
       retirement of Cabot's Chief Executive Officer. Included in the charge is
       a $10 million non-cash charge to accelerate the vesting of common stock
       issued under the company's long term incentive compensation plan and an
       accrual for a $7 million cash payment. The cash payment was made during
       the third quarter.

       On March 16, 2001, Cabot UK Holdings Limited, a wholly owned subsidiary
       of Cabot Corporation, announced an open offer for approximately 3.5
       million shares of Cabot India Limited, at 100 Rupees per share. Cabot
       India Limited is a majority owned subsidiary of Cabot Corporation and its
       shares are traded on the Mumbai Stock Exchange and the National Stock
       Exchange of India. The tender offer is for the 40% ownership of Cabot
       India Limited currently held by minority interest shareholders. The offer
       period is expected to end on June 16, 2001.

       In March, 2001 Cabot exercised an option to purchase 1 million shares of
       Angus & Ross Plc common stock. In May, 2001 Cabot concluded an agreement
       to purchase an additional 4 million shares of Angus & Ross Plc common
       stock. The total purchase price of the 5 million shares was approximately
       $1 million. The purchase of the additional 4 million shares increased
       Cabot's ownership in Angus & Ross Plc to approximately 21%. The
       investment will be accounted for under the equity method starting in the
       third quarter of fiscal 2001. As part of the agreement, Cabot received an
       option to purchase an additional 5 million shares of common stock. The
       option has not yet been exercised.

       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 were accruals of $2 million for severance and
       termination benefits for approximately 40 employees of the Chemical and
       Performance Materials Businesses and $7 million for facility closing
       costs, of which none were paid out in fiscal 2000. The remainder of the
       charge included $9 million for the impairment of long-lived assets. As of
       March 31, 2001, $8 million remains in the accrual, of which $2 million
       relates to severance and $6 million to other facility closing costs. Most
       of the accrual will be expended during fiscal 2001.

       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 March 31, 2001. The remaining
       $1 million is expected to be expended in fiscal 2001.

       On September 19, 2000, Cabot completed a transaction to sell its
       liquefied natural gas (LNG) business 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 business
       recorded in the fourth quarter of fiscal 2000, was approximately $309
       million, net of taxes of $178 million.

       In February, 2001, Cabot received additional cash proceeds of $5 million
       from the sale. The receipt, net of taxes, is classified as a gain on the
       sale of LNG in the Consolidated Statement of Income.

       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 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 March 31, 2001, 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.

               was greater than the average market price of the common shares
               for 2000. As of March 31, 2001, the average fair value of Cabot's

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 MARCH 31, 2001 VERSUS
THREE MONTHS ENDED MARCH 31, 2000

Net income from continuing operations for the second quarter of fiscal 2001 was
$28 million ($0.36 per diluted common share) compared to $28 million ($0.39 per
diluted common share) in the same quarter a year ago. Included in this quarter's
results is a $17 million ($0.16 per diluted share) special charge related to the
retirement of Cabot's Chief Executive Officer, consisting of a $10 million
non-cash charge to accelerate the vesting of stock issued under the Company's
long term incentive compensation plan and an accrual for a $7 million cash
payment.

Companywide sales increased 15% from $397 million last year to $458 million
this year due to higher prices in the Chemical Businesses and higher volumes and
prices in the Performance Materials segment. Overall operating profit before
taxes and the special charge of $17 million increased 23% from $43 million in
the second quarter of fiscal 2000 to $53 million in the second quarter of fiscal
2001. Higher prices and lower production costs in the Chemical Businesses
absorbed the effects of higher feedstock costs and resulted in improved margins.
In addition, the Company benefited from higher tantalum margins resulting from
customer contracts entered into in the second quarter of fiscal 2001.

Sales for the Chemical Businesses increased to $357 million. Operating profit
decreased from $49 million to $35 million. The $14 million, or 29%, decrease in
profitability is primarily attributed to slower industrial growth in North
America, increased carbon black feedstock costs, higher natural gas costs, and
unfavorable currency movements.

For the second quarter of fiscal 2001, global carbon black volumes decreased 6%
versus the second quarter of last year. Sales volumes were flat in both South
America and Europe though a weaker North American economy led to a 16% decrease
in volumes in that region. Similarly, Asia Pacific experienced a 3% decrease in
volumes. Carbon black was negatively impacted by increased feedstock costs.
Feedstock costs were 25% higher in the second quarter of this year versus the
same quarter a year ago due to increases in oil and natural gas prices.

Overall volumes in the Fumed Metal Oxides business declined by 8% due to
decreased demand from traditional markets including the silicone rubber and
construction industries. However, higher prices offset lower volumes resulting
in a 9% increase in sales year over year. Results were negatively impacted by
higher energy prices and manufacturing costs in North America.

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

Performance Materials sales were $103 million in the second quarter of fiscal
2001 compared with $54 million in fiscal 2000. Demand for tantalum products
continues to remain strong. Volumes of tantalum sold were 26% higher in the
second quarter of 2001 than in the same quarter a year ago. As a result of the
customer contracts entered into during the second fiscal quarter of 2001,
average prices increased approximately 56% year over year. At the same time,
total costs increased approximately 67% due to higher volumes and higher ore
costs. It is anticipated that Cabot's earnings in the tantalum

                                CABOT CORPORATION

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

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 estimates for fiscal 2001.

Specialty Fluids sales in the second quarter were $5 million versus $6 million
last year. Lower volumes and prices were offset by lower operating costs
resulting in flat operating results in the second quarter of fiscal 2001 versus
the same quarter in 2000. Sales to date have been generated from the production
and sale of cesium formate as well as spodumene, tantalum and fine cesium
chemicals. During the second quarter, cesium formate was used in two successful
drill-in applications involving challenging high pressure, high temperature
wells in the North Sea. It is anticipated that these wells will undergo
production flow tests in the near future.

Interest income in the second quarter of this year was $6 million higher than in
the same quarter last year due to an increase in Cabot's cash position related
to the sales proceeds of the Liquefied Natural Gas business.

Research and technical service spending was $12 million for the second quarter
versus $11 million for the second quarter of last year. Selling and
administrative expenses were $52 million for the second quarter of fiscal 2001,
an 18% increase from $44 million spent last year. The increase is largely due to
non-capitalized expenses associated with the development and implementation of
our Enterprise Resource Planning system, accounting for stock-based incentive
compensation and our e-commerce initiative which has been expanded this year.
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 February 2001, Cabot received $3 million, net of tax, ($0.04 per diluted
common share) of additional proceeds from the September 2000 sale of the
Liquefied Natural Gas business.

In fiscal 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% in fiscal 2000 to 29% in fiscal 2001.

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
were accruals of $2 million for severance and termination benefits and $7
million for facility closing costs. As of March 31, 2001, $8 million is accrued,
of which $2 million relates to severance and the remaining $6 million to
facility closing costs. Most of the $8 million will be expended during fiscal
2001.

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
March 31, 2001. The remaining $1 million is expected to be expended during
fiscal 2001.

SIX MONTHS ENDED MARCH 31, 2001 VERSUS
SIX MONTHS ENDED MARCH 31, 2000

Net income from continuing operations for the first six months of fiscal 2001
was $56 million compared to $59 million for the first half of fiscal 2000.
Included in these results from operations for the first half of fiscal 2001 is a
$17 million special charge related to the retirement of Cabot's Chief Executive
Officer.

Sales increased 10% from $774 million last year to $853 million this year due to
strong volumes and pricing in the Performance Materials segment and higher
prices in the carbon black business. However, operating profit before taxes and
a special charge of $17 million decreased slightly from $92 million in the first
half of fiscal 2000 to $90 million in the first half of fiscal 2001. Increased
feedstock costs in the Chemical Businesses and higher raw material costs in the

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

Performance Materials business were the primary drivers behind the decrease in
profitability. Increased pricing in the Performance Materials business did not
begin to offset higher ore costs until the second quarter of fiscal 2001.

Sales for the Chemical Businesses increased to $691 million. Operating profit
decreased from $102 million to $76 million. The $26 million, or 25%, 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.

Performance Materials sales were $159 million, a 51% increase from $105 million
in the first six months of fiscal 2000. Operating profit increased 44% from $16
million in the first six months of last year to $23 million in the first two
quarters of this year driven by higher volumes and higher prices.

Specialty Fluids realized a $2 million improvement in sales for the six-month
period ended March 31, 2001. Sales increased from $10 million last year to $12
million this year. Similarly, Specialty Fluids realized a $3 million improvement
in profitability for the first half of fiscal 2001, largely as a result of
improved pricing and increased volumes.

In February 2001, Cabot received $3 million, net of tax, ($0.04 per diluted
common share) of additional proceeds from the September 2000 sale of the
Liquefied Natural Gas business.

II. CASH FLOW AND LIQUIDITY

During the first six months of the fiscal year, cash used in operating
activities totaled $131 million as compared to cash provided by operating
activities of $72 million for the same period last year. The uses of cash during
the first quarter of fiscal 2001 included a tax payment related to the September
2000 disposition of the Liquefied Natural Gas business.

Capital spending for the first six months of the year was $36 million. The
majority of capital spending related to maintaining existing assets. Cabot plans
to spend approximately $160 million on capital expenditures during the fiscal
year.

Cash used by financing activities was $29 million in the first half of fiscal
2001 as compared to $1 million provided by financing activities for the same
period last year. The key components of the charge in net cash from financing
activities were the acquisition of a 3-year EURO note for $129 million, the
repayment of $63 million in long-term debt, and the repurchase of $83 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 March 31, 2001, approximately 3 million shares have been purchased at an
average price of $28 per share under this new authorization.

During the second quarter of fiscal 2001, Cabot entered into a knock-in share
repurchase contract with an investment bank. The contract allowed for the
purchase of up to 2 million shares of Cabot's common stock at various market
prices from April 1, 2001 to April 28, 2001. The contract expired without being
triggered.

On March 16, 2001, Cabot UK Holdings Limited, a wholly owned subsidiary of Cabot
Corporation, announced an open offer for approximately 3.5 million shares of
Cabot India Limited, at 100 Rupees per share. Cabot India Limited is a majority
owned subsidiary of Cabot Corporation and its shares are traded on the Mumbai
Stock Exchange and the National Stock Exchange of India. The tender

OF OPERATIONS (CONTINUED)

offer is for the 40% ownership of Cabot India Limited currently held by minority
interest shareholders. The offer period is expected to end June 16, 2001.

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
decreased from 4% to 2% at March 31, 2001.

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 March 31, 2001, 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.
