                                CABOT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 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 June 30, 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 $4 million charge was recorded, related to the
     resignation of Cabot's Chief Financial Officer. Included in the charge is a
     $3 million non-cash charge to accelerate the vesting of common stock issued
     under the company's long term incentive compensation plan and a $1 million
     cash payment. Also included in special items for fiscal 2001 is the $17
     million charge recorded in the second quarter, related to the retirement of
     Cabot's Chief Executive Officer. The $17 million charge included a $10
     million non-cash charge to accelerate the vesting of common stock issued
     under the company's long term incentive compensation plan and a $7 million
     cash payment.

     On June 16, 2001, the open offer for approximately 3.5 million shares of
     Cabot India Limited closed. Cabot India Limited is a majority-owned
     subsidiary of Cabot Corporation and its shares are traded on Indian stock
     exchanges. The tender offer was for the 40% ownership of Cabot India
     Limited held by minority interest shareholders. The approval and share
     transfer procedures occurred in July 2001. Approximately 2.8 million of the
     outstanding shares were acquired for $6 million, raising Cabot's total
     ownership to 92.5%. Cabot intends to make a follow-on offer at the same
     price for the remaining shares.

     In March 2001, Cabot exercised an option to purchase 1 million shares of
     Angus & Ross Plc common stock. In May 2001, Cabot purchased 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 is accounted for under the equity
     method. 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 two plants. In relation
     to the plant closings, Cabot recorded an $18 million charge in the fourth
     quarter of fiscal 2000. 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. During the quarter ended June 30, 2001, $1 million of
     severance and termination benefits, $1 million of facility closing costs
     and the impact of foreign exchange reduced the reserve by $3 million. It
     was determined during the quarter that the recovery value of fixed assets
     were overvalued by $2 million and the required facility closing costs would
     be $2 million less than originally accrued. As of June 30, 2001, $4 million
     is accrued for the remaining severance and facility closing cost
     obligations.

                                    UNAUDITED

     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 June 30, 2001.

C.   DISCONTINUED OPERATIONS

     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

     In July 2001 Cabot replaced its revolving credit and term loan facility
     with a new agreement. Under the new agreement Cabot may borrow up to $250
     million at floating rates. The new credit facility matures on July 13,
     2006. The agreement contains specific covenants, including maximum
     indebtedness limitations and earnings before interest, taxes, depreciation,
     and amortization ("EBITDA") requirements, that would limit the amount
     available for future borrowings. Commitment fees are paid based on the used
     and unused portions of the credit facility. At June 30, 2001, no amount was
     outstanding under the previous credit facility.

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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
                                  June 30, 2001
                                    UNAUDITED

     As of June 30, 2001, Cabot has approximately $33 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.

F.   NEW ACCOUNTING STANDARDS

     In June 2001, the Financial Accounting Standards Board ("FASB") issued
     Statement of Financial Accounting Standards No. 141, Business Combinations
     ("SFAS 141"), which requires that the purchase method of accounting be used
     for all business combinations initiated after June 30, 2001, establishes
     specific criteria for the recognition of intangible assets separately from
     goodwill, and requires that unallocated negative goodwill be written off
     immediately as an extraordinary gain instead of being deferred and
     amortized. Cabot will account for its future business combinations in
     accordance with the guidance in SFAS 141.

     In June 2001, the FASB issued Statement of Financial Accounting Standards
     No. 142, Goodwill and Other Intangible Assets ("SFAS 142"). Under SFAS 142
     goodwill and indefinite lived intangible assets will no longer be
     amortized. Instead, goodwill will be subject to annual impairment tests
     performed under the guidance of the statement. Additionally, the
     amortization period of intangible assets with finite lives will no longer
     be limited to forty years. The general provisions for SFAS 142 will be
     effective for Cabot at the beginning of fiscal 2003. Cabot is currently
     assessing the potential impact of implementing SFAS No 142 and expects
     amortization expense to be reduced in future periods.

(2) Of the options to purchase shares of common stock outstanding at June 30,
    2000, 0.2 million shares were not included in the computation of diluted
    EPS because those options' exercise price was greater than the average
    market price of the common shares for 2000. As of June 30, 2001, the
    average fair value of Cabot's stock price exceeded the exercise price of all
    options outstanding. As such, all options outstanding have been included in
    the calculation of fully diluted earnings per share.

J.   FINANCIAL INFORMATION BY SEGMENT (CONTINUED)

     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 nine
     months ended June 30:

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 J to
the Consolidated Financial Statements.

THREE MONTHS ENDED JUNE 30, 2001 VERSUS
THREE MONTHS ENDED JUNE 30, 2000

Net income from continuing operations for the third quarter of fiscal 2001 was
$38 million ($0.51 per diluted common share) compared to $38 million ($0.51 per
diluted common share) in the same quarter a year ago. Included in this quarter's
results is a $4 million ($0.04 per diluted share) special charge related to the
resignation of Cabot's Chief Financial Officer, consisting of a $3 million
non-cash charge to accelerate the vesting of stock issued under the Company's
long term incentive compensation plan and a $1 million cash payment. Included in
results for the third quarter of 2000 is an $8 million ($0.07 per diluted share)
special item benefit from the settlement of insurance litigation.

Cabot's sales increased 5% from $414 million last year to $436 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 increased 11% from $45 million in the third quarter of fiscal
2000 to $50 million in the third quarter of fiscal 2001. Lower volumes, higher
feedstock costs, and a stronger US dollar offset the benefits of higher prices
and lower production costs in the Chemical Businesses. In addition, the Company
benefited from higher tantalum margins resulting from customer contracts entered
into in the first quarter of fiscal 2001.

Sales for the Chemical Businesses decreased from $357 million to $336 million.
Operating profit decreased from $48 million to $30 million. The $18 million, or
38%, decrease in profitability is primarily attributed to slower industrial
growth in North America and Europe, increased carbon black feedstock costs,
higher natural gas costs, and unfavorable currency movements.

For the third quarter of fiscal 2001, global carbon black volumes decreased 9%
versus the third quarter of last year. Sales volumes decreased 22% in North
America and 10% in Europe due to weakened economic conditions. South America
experienced a 5% decrease in volumes, largely due to the Brazilian energy
crisis. However, increased sales in Indonesia and China resulted in a 15% volume
increase in Asia Pacific. While the business benefited from lower production
costs, carbon black profitability was negatively impacted by weaker demand, a
strong US dollar and increased oil-based feedstock and natural gas costs.

Overall volumes in the fumed metal oxides business declined 11% due to decreased
demand in North America and Asia from traditional markets including the silicone
rubber and construction industries. Demand from the electronics sector remained
flat. Results were negatively impacted by higher energy prices and
administrative costs. In addition, the business absorbed increased costs
associated with capacity expansions put in place in fiscal 2000.

Cabot's inkjet colorants business reported a 9% increase in volumes; however,
higher administrative costs resulted in a $1 million decrease in operating
profit in the third quarter of 2001.

Performance Materials sales were $99 million in the third quarter of fiscal 2001
compared with $56 million in the same quarter of fiscal 2000. Volumes of
tantalum sold were 11% higher in the third quarter of 2001 than in the
comparative quarter a year ago. As a result of the customer contracts entered
into during the first fiscal quarter of 2001, average prices increased
approximately 62% quarter over quarter. At the same time, total costs increased
approximately 48% due to higher volumes and higher ore costs. It is


                                       20
   21


anticipated that Cabot's earnings in the tantalum business will increase by
as much as 100% in fiscal 2001, year over year.

Specialty Fluids sales in the third quarter were flat at $6 million versus the
year ago quarter. However, higher administrative and selling costs resulted in a
$1 million decrease in profit. Through the third quarter of 2001, cesium formate
has been successfully used in a total of 41 completion and drill-in applications
involving challenging high pressure, high temperature wells in the North Sea.
Additionally, recent indications of the flow-rate tests of the initial three
drill-in jobs have been very positive. Cesium formate improved drilling speed,
minimized skin damage, and substantially improved flow rates.

Interest income in the third quarter of this year was $5 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 and an increase in
operating income.

Research and technical service spending was flat at $12 million for the third
quarter versus the year ago quarter. Selling and administrative expenses were
$55 million for the third quarter of fiscal 2001, a 31% increase from $42
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 as a percentage of sales increased from 10% to 13% in
the third fiscal quarter of 2001. Research and technical service spending
remained flat at 3% as a percentage of sales for the same time period.

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 is anticipated to decrease from 36% in fiscal 2000 to 29% in
fiscal 2001.

During fiscal 2000, Cabot approved plans to close two plants. In relation to the
plant closings, Cabot recorded an $18 million charge in the fourth quarter of
fiscal 2000. Included in the charge were accruals of $2 million for severance
and termination benefits for approximately 40 employees 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. During the quarter ended June 30, 2001, $1 million of severance and
termination benefits, $1 million of facility closing costs, and the impact of
foreign exchange reduced the reserve by $3 million. In addition, it was
determined during the quarter that the recovery value of fixed assets was
overvalued by $2 million and the required facility closing costs would be $2
million less than originally accrued. As of June 30, 2001, $4 million remains in
the accrual.

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
June 30, 2001.

NINE MONTHS ENDED JUNE 30, 2001 VERSUS
NINE MONTHS ENDED JUNE 30, 2000

Net income from continuing operations for the nine months ended June 30, 2001
was $93 million compared to $96 million for the same period in fiscal 2000.
Included in these results from operations for fiscal 2001 are special charges of
$21 million ($0.20 per diluted share) related to the retirement of Cabot's Chief
Executive Officer and the resignation of Cabot's Chief Financial Officer.
Included in results for the nine months ended June 30, 2000 is an $8 million
($0.07 per diluted share) special item benefit from the settlement of insurance
litigation.

Sales increased 9% from $1,187 million last year to $1,289 million this year due
to strong volumes and pricing in the Performance Materials segment and higher
prices in the Chemical Businesses. Operating profit before taxes and special
charges increased slightly from $136 million for the nine months ended June 30,
2000 to $138 million for the nine months ended June 30, 2001. Increased
feedstock costs in the Chemical Businesses, higher raw material costs in the
Performance Materials business, and unfavorable currency trends somewhat offset
increased pricing in the Performance Materials and carbon black businesses.


                                       21
   22


Sales for the Chemical Businesses increased slightly to $1,027 million this year
from $1,025 million last year. Operating profit decreased from $150 million to
$106 million. The $44 million, or 29%, decrease in profitability is primarily
attributed to lower volumes, increased oil-based feedstock and natural gas
costs, and unfavorable currency trends.

Performance Materials sales were $257 million, a 60% increase from $161 million
in the first nine months of fiscal 2000. Operating profit increased 104% from
$26 million in the first nine months of last year to $53 million in the first
nine months of this year driven by higher volumes and higher prices.

Specialty Fluids realized a $3 million improvement in sales for the nine months
ended June 30, 2001. Sales increased from $16 million last year to $19 million
this year. Similarly, Specialty Fluids realized a $2 million improvement in
profitability for the nine months ended June 30, 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 nine months of the fiscal year, cash used in operating
activities totaled $44 million as compared to cash provided by operating
activities of $181 million for the same period last year. The uses of cash
during the nine months of fiscal 2001 included a tax payment of $179 million
related to the September 2000 disposition of the Liquefied Natural Gas business.

Capital spending for the first nine months of the year was $70 million. The
majority of capital spending related to improvements to existing assets. Cabot
plans to spend approximately $130 million on capital expenditures during the
fiscal year.

Cash used by financing activities was $135 million for the nine months ended
June 30, 2001 as compared to $69 million used by financing activities for the
same period last year. The key components of the change in net cash from
financing activities were the repurchase of $185 million of common stock and the
repayment of $63 million in long-term debt net of proceeds from the issuance of
a 3-year EURO note for $129 million.

In November 2000, a Cabot subsidiary issued a 150 million EURO Note ($129
million) to a group of institutional lenders. The loan bears interest at EURIBOR
plus 0.70% and is scheduled to mature in November 2003. The loan is guaranteed
by Cabot Corporation.

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 June 30, 2001, approximately 5.7 million shares have been purchased at an
average price of approximately $32 per share under this new authorization.

In the third quarter of fiscal 2001, Cabot entered into an equity contract for
the purchase of Cabot Corporation common stock. During the contract period Cabot
purchased 100,000 shares for approximately $35 per share.

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
Bombay Stock Exchange and the National Stock Exchange of India. The tender offer
was for the 40% ownership of Cabot India Limited currently held by minority
interest shareholders. The open offer closed on June 16, 2001 and the approval
and share transfer procedures occurred in


                                       22
   23


July 2001. Approximately 2.8 million of the outstanding shares were acquired for
$6 million, raising Cabot's total ownership to 92.5%. Cabot intends to make a
follow-on offer at the same price for the remaining shares.

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 2% at March 31, 2001 to 6% at June 30, 2001.

In July 2001, Cabot replaced its revolving credit and term loan facility with a
new agreement. Under the new agreement Cabot may, under certain conditions,
borrow up to $250 million at floating rates. The new credit facility matures on
July 13, 2006. At June 30, 2001, Cabot had no borrowings outstanding under the
previous credit facility. 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 June 2001, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 141, Business Combinations ("SFAS 141"),
which requires that the purchase method of accounting be used for all business
combinations initiated after June 30, 2001, establishes specific criteria for
the recognition of intangible assets separately from goodwill, and requires that
unallocated negative goodwill be written off immediately as an extraordinary
gain instead of being deferred and amortized. Cabot will account for its future
business combinations in accordance with the guidance in SFAS 141.

In June 2001, the FASB issued Statement of Financial Accounting Standards No.
142, Goodwill and Other Intangible Assets ("SFAS 142"). Under SFAS 142 goodwill
and indefinite lived intangible assets will no longer be amortized. Instead,
goodwill will be subject to annual impairment tests performed under the guidance
of the statement. Additionally, the amortization period of intangible assets
with finite lives will no longer be limited to forty years. The general
provisions for SFAS 142 will be effective for Cabot at the beginning of
fiscal 2003. Cabot is currently assessing the potential impact of implementing
SFAS No 142 and expects amortization expense to be reduced in future periods.

     FORWARD-LOOKING INFORMATION: Included above are statements relating to
management's expectations of future profits, the possible achievement of Cabot's
financial goals and objectives and management's expectations for shareholder
value creation initiatives and for Cabot's product development program. Actual
results may differ materially from the results anticipated in the statements
included herein due to a variety of factors, including market supply and demand
conditions, fluctuations in currency exchange rates, costs of raw materials,
patent rights of others, stock market conditions, demand for our customers'
products and competitors' reactions to market conditions, and other factors
referred to in Cabot's filings with the Securities and Exchange Commission.
Timely commercialization of products under development by Cabot may be disrupted
or delayed by technical difficulties, market acceptance, competitors' new
products, as well as difficulties in moving from the experimental stage to the
production stage. Cabot undertakes no obligation to update forward-looking
statements or reflect events or circumstances after the date of this document.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

     (a)  In June, 2001 Cabot signed a Consent Order with the West Virginia
          Department of Environmental Protection, Office of Air Quality (the
          "Agency") regarding Cabot's carbon black manufacturing facility in
          Waverly, West Virginia. The Consent Order resolves claims by the
          Agency that the Waverly facility was not in compliance with certain
          air permitting and regulatory requirements. Under the Consent Order,
          Cabot was required to submit a penalty payment of $200,000 to the
          Agency's Air Pollution and Education Fund. Cabot is also required to
          submit an air permit application to the Agency by September 1, 2001.
          The Consent Order also imposes certain operational and recordkeeping
          requirements on the Waverly facility, none of which are expected to
          have a material adverse effect on the Company.

     (b)  A number of lawsuits and claims have been filed against other
          corporate entities which relate to the Company's former safety
          respiratory product business. The Company may be liable with respect
          to numerous lawsuits involving respirators sold by American Optical
          Corporation prior to April 1990 or a subsidiary of the Company from
          April 1990 to July 1995. These lawsuits typically involve plaintiffs
          alleging that they suffer from asbestosis or silicosis, and that such
          condition results in part from respirators which were negligently
          designed or manufactured. The defendants in these lawsuits are often
          numerous, and include, in addition to respirator manufacturers,
          employers of the plaintiffs and manufacturers of sand used in sand
          blasting and asbestos. Responsibility for legal costs, as well as for
          settlements and judgments, is shared contractually by the Company,
          American Optical Corporation and a prior owner of American Optical
          Corporation. The Company disposed of the respirator business in July
          1995 to Aearo Corporation ("Aearo"). The Company and Aearo have
          entered into an arrangement whereby, so long as Aearo pays to Cabot an
          annual fee of $400,000, which Aearo has elected to pay, Cabot will
          retain responsibility and liability for, and indemnify Aearo against,
          certain legal claims asserted after July 11, 1995 (the date of Aearo's
          formation) to the extent these claims are alleged to arise out of the
          use of American Optical respirators prior to July 1995. Aearo has the
          right to discontinue the payment of such annual fee at any time, in
          which case Aearo will assume responsibility for and indemnify Cabot
          with respect to such claims. It is management's opinion, taking into
          account currently available information, past experience, contractual
          obligations and insurance coverage which may be applicable to such
          matters, that these suits and claims should not result in final
          judgments or settlements that, in the aggregate, would have a material
          effect on the Company's financial condition or results of operations.
