CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS June 30, 2002 (In millions, except per share amounts) 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, 2001. The financial information submitted herewith is unaudited and reflects all adjustments that are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods ended June 30, 2002 and 2001. 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. Certain amounts in fiscal 2001 have been reclassified to conform to the fiscal 2002 presentation. These reclassifications had no affect on operating income. B. SPECIAL ITEMS AND DISCONTINUED OPERATIONS During the third quarter of fiscal 2002, Cabot recorded special items of $7 million. Included in this amount is a $5 million charge for respirator claims derived from a disposed safety products business, a $3 million asset impairment charge for the cancellation of expansion projects at the Performance Materials plant in Boyertown, Pennsylvania, related to the acquisition of Showa Cabot Supermetals KK, now known as Cabot Supermetals (CSM), and a $1 million benefit from insurance recoveries. Additional disclosure of the respirator claims reserve is included in Note G, Commitments and Contingencies. The Company recorded $3 million of special items during the second quarter of fiscal 2002 associated with the acquisition of CSM, including $2 million for an asset impairment charge from the cancellation of an expansion project at the Performance Materials plant in Boyertown, Pennsylvania, and $1 million of non-capitalizable transaction costs. During the third quarter of fiscal 2001, a $4 million charge was recorded, related to the resignation of Cabot's Chief Financial Officer. Included in the charge was 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 was the $17 million charge 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. 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 38 employees of the Chemical and Performance Materials businesses, $7 million for facility closing costs, and a $9 million charge for the impairment of long-lived assets. One of the plant closures was completed during fiscal 2001, and the second plant closure was completed during the second quarter of fiscal 2002. As of June 30, 2002 all severance and termination benefits have been paid. At June 30, 2002, $2 million remains accrued for the required monitoring costs at the second site. -9-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS June 30, 2002 (In millions, except per share amounts) UNAUDITED On September 19, 2000, Cabot completed a transaction to sell its liquefied natural gas (LNG) business for approximately $688 million in 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 sale of discontinued business in the consolidated statements of income. In May 2002, Cabot recorded an insurance recovery of $1 million from the discontinued business. The receipt, net of taxes, is classified as income from operations of a discontinued business in the consolidated statements of income. C. ACQUISITION On February 8, 2002, Cabot Corporation purchased the remaining 50% of the shares in CSM in Japan, from its joint venture partner, Showa Denko KK. CSM is a supplier of tantalum powders and metal products to the global electronics, aerospace, and chemical processing industries. The acquisition of CSM expands the capacity and the capabilities of Cabot's existing tantalum business. This acquisition has been accounted for as a purchase and the results of operations of CSM have been included in the consolidated financial statements since the date of acquisition, on a one-month lag due to a delay in the availability of financial information. Prior to the acquisition, Cabot's investment in CSM was accounted for as an equity investment and the results were reported on a three-month lag. The equity investment income for the final three-month period prior to the acquisition was not material to the consolidated results of operations. Included in the consolidated results of Cabot Corporation for the nine months ended June 30, 2002, are 50% of the operating results of CSM for the months of July 2001 through January 2002 and 100% of the operating results of CSM for the months of February through May 2002. The fair value of the debt assumed and assets and liabilities acquired represents the 50% of CSM purchased. A summary of the consideration paid and the allocation of the purchase price of the acquisition is as follows: Cash paid $ 99 Fair value of debt assumed 53 ---- Total consideration $152 ==== Fair value of tangible and intangible assets acquired $104 Fair value of liabilities assumed 22 ---- Fair value of net assets acquired $ 82 ==== Recorded goodwill $ 70 ==== Allocation of the purchase price is based on estimates of the fair value of the net assets acquired and is subject to adjustment. Cabot is not aware of any information that would indicate that the final purchase price allocations will differ significantly from preliminary estimates. -10-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS June 30, 2002 (In millions, except per share amounts) UNAUDITED Assuming Cabot owned 100% of Cabot Supermetals for all periods presented, the following table would be the unaudited pro forma consolidated operating results for the three and nine months ended June 30, 2002 and 2001: Three Months Ended June 30 Nine Months Ended June 30 -------------------------- ------------------------- 2002 2001 2002 2001 ---- ---- ---- ---- Total Revenues $ 390 $ 471 $ 1,144 $ 1,400 Net Income 19 39 82 105 Net Income Per Share: Basic $ 0.32 $ 0.61 $ 1.34 $ 1.63 Diluted $ 0.28 $ 0.53 $ 1.15 $ 1.39 The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the actual results of operations had the acquisition taken place in the prior year or the results that may occur in the future. Furthermore, the pro forma results do not give effect to all cost savings or incremental costs that may occur as a result of the integration and consolidation of Cabot Supermetals. D. GOODWILL AND OTHER INTANGIBLE ASSETS Cabot adopted Statement of Financial Accounting Standards (FAS) No. 142, "Goodwill and Other Intangible Assets" on October 1, 2001. Under FAS No. 142, all goodwill amortization ceased for Cabot on October 1, 2001. Upon adoption, the goodwill attributable to each reporting unit was tested for impairment by comparing the fair value of each reporting unit to its carrying value. The fair value of a reporting unit was determined by estimating the present value of expected future cash flows. No impairments existed upon adoption of FAS No. 142. As required by FAS No. 142, impairment tests will be performed at least annually. During the third quarter of fiscal 2002, Cabot performed the fiscal 2002 FAS No. 142 impairment test and determined that no impairment loss should be recognized. At June 30, 2002 and September 30, 2001, Cabot had goodwill balances of $101 million and $19 million, respectively. During the first quarter of 2002, Cabot acquired shares of certain minority interest shareholders in the Chemical Businesses, resulting in $5 million of additional goodwill. During the second quarter of 2002, Cabot acquired the remaining 50% of the shares in CSM in the Performance Materials business, resulting in $70 million of additional goodwill. The carrying amount of goodwill attributable to each reportable operating segment with goodwill balances and the changes in those balances during the nine months ended June 30, 2002 are as follows: Chemical Performance Business Materials Total -------- --------- ----- Balance at September 30, 2001 $16 $ 3 $ 19 Goodwill acquired during period 5 70 75 Foreign exchange translation adjustment 1 6 7 --- --- ---- Balance at June 30, 2002 $22 $79 $101 === === ==== Cabot does not have any indefinitely lived intangible assets. At June 30, 2002, Cabot had $8 million of finite-lived intangible assets primarily composed of know-how. At September 30, 2001, Cabot had $2 million of finite-lived intangible assets. Intangible assets are amortized over their estimated useful lives, -11-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -(Continued) June 30, 2002 (In millions, except per share amounts) UNAUDITED which range from two to fifteen years. Estimated amortization expense is expected to be approximately $1 million in each of the next five years. If FAS No. 142 had been adopted in the prior period Cabot's pro forma net income and pro forma net income per common share for the three and nine months ended June 30, 2001 would have been: Three Months Ended Nine Months Ended ------------------ ----------------- 2001 2001 ---- ---- Net Income available for common shares- as reported $ 38 $ 94 Goodwill amortization, net of tax benefit 1 2 ------ ------ Net income available for common shares- pro forma $ 39 $ 96 ====== ====== Net income per common share - pro forma: Basic $ 0.60 $ 1.52 Diluted $ 0.52 1.30 E. NOTES PAYABLE AND LONG-TERM DEBT On February 8, 2002, the date of acquisition, CSM had notes payable to banks and long-term debt from institutional lenders denominated in Japanese yen. Because the notes payable to banks have renewable one year terms, they are classified as current liabilities on the consolidated balance sheet. The total principal balance of the notes at acquisition was 6.25 billion yen ($47 million on February 8, 2002). The interest rates on 1.3 billion yen of the bank notes are fixed and range from 0.7% to 0.8%. The interest rates on the remaining bank notes are variable and based on short-term interest rates. Since acquiring CSM, Cabot has repaid the 1.3 billion yen fixed-rate bank notes. At June 30, 2002, the outstanding principal balance on the bank notes is approximately $40 million when translated to US dollars. The long-term debts of CSM are also payable in Japanese yen and mature on various dates in fiscal years 2004 to 2006. The principal balance on the long-term debt at acquisition was 7.8 billion yen ($59 million on February 8, 2002). The interest rates on 3.3 billion yen of the loans are fixed and range from 1.5% to 2.1%. The interest rates on the remaining long-term loans are variable and based on short term interest rates. At June 30, 2002, the principal balance on the long-term debt is approximately $63 million when translated to US dollars. Principal payments on the CSM long-term debt in each of the five fiscal years 2002 through 2006 are zero, zero, $11 million, $20 million, and $32 million, respectively. Maximum amounts and additional advances under some of the CSM loan agreements are subject to CSM's ongoing creditworthiness. As of June 30, 2002, Cabot is not aware of any credit concerns under CSM's loan agreements. F. FINANCIAL INSTRUMENTS In October 2001, Cabot entered into four interest rate swaps in an aggregate notional amount of $97 million. The swaps are derivative instruments as defined by FAS No. 133,"Accounting for Derivative Instruments and Hedging Activities", and have been designated as fair value hedges. The swaps hedge the change in the fair value of $97 million of Cabot's fixed rate medium term notes due to changes in interest rates. The interest rate swaps and the medium term notes they hedge mature on various dates through February 2007. A derivative asset and a corresponding increase to long term debt of $1 million were recorded for the fair market value of the swaps at June 30, 2002. The interest rate swaps were determined -12-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -(Continued) June 30, 2002 (In millions, except per share amounts) UNAUDITED to be highly effective and no amount of ineffectiveness needed to be recorded in earnings during the period ended June 30, 2002. As part of the CSM acquisition, Cabot assumed interest rate swaps related to 5.7 billion yen of the variable rate debt . The swaps hedge the risk of changes in market interest rates associated with the variable interest on the debt. The swaps are variable-for-fixed swaps of the quarterly interest payments. The swaps require payment of fixed rates ranging from 1.5% to 2.2% and the receipt of variable rates based on short-term interest rates. The swaps mature, along with the associated loans, in fiscal 2002 through 2006. The swaps are derivative instruments as defined by FAS No. 133 and have been designated as cash flow hedges. The interest rate swaps were recorded at their fair value of $1 million on the acquisition date as a reduction in debt. Subsequent changes in the fair value of these cash flow hedges, which have not been significant, are recorded in other comprehensive income. Derivative financial instruments are used by Cabot to manage some of its foreign currency exposures. Cabot may also use financial instruments to manage other exposures, such as commodity prices, share repurchases and interest rates. Cabot does not enter into financial instruments for speculative purposes. Cabot has formally documented the relationships between hedging instruments and hedged items, as well as its risk management objective. All derivative instruments are recognized on the balance sheet at fair value. Hedge accounting is followed for derivatives that have been designated and qualify as fair-value and cash flow hedges. Changes in the fair value of highly effective derivatives, along with changes in the fair value of the hedged liabilities that are attributable to the hedged risks, are recorded in current period earnings. For derivatives that have been designated and qualify as cash flow hedges, changes in the fair value of the effective portion of the derivatives' gains or losses are reported in other comprehensive income, and the ineffective portion is reported in earnings. By using derivative instruments, Cabot is subject to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, Cabot's credit risk will equal the fair-value gain on the derivative. Generally, when the fair value of a derivative contract is positive, the counterparty owes Cabot, thus creating a repayment risk for Cabot. When the fair value of a derivative contract is negative, Cabot owes the counterparty and, therefore, assumes no repayment risk. Cabot minimizes the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by Cabot. G. 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. The Company has exposure to a safety respiratory products business that it acquired in April 1990. It disposed of that business in July 1995. In connection with its acquisition of the business, the Company agreed, after an initial period during which responsibility was shared, to indemnify the seller, American Optical Corporation, ("American Optical"), for costs, including legal costs, settlements and judgments, in connection with a number of lawsuits and claims relating to the respirators (in exchange for which the Company received the benefits of the seller's insurance and other indemnities). These lawsuits and claims typically involve allegations that the plaintiffs suffer from asbestosis or silicosis as a result, in part, from respirators that were negligently designed or labeled. The defendants in these lawsuits are often numerous and include, in addition to respirator manufacturers, makers of asbestos and sand used in sand blasting. -13-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -(Continued) June 30, 2002 (In millions, except per share amounts) UNAUDITED Neither the Company, nor its past or present subsidiaries, at any time manufactured asbestos or asbestos-containing products. Moreover, not every person with exposure to asbestos giving rise to an asbestos claim used a form of respiratory protection. At no time did the business for which the Company is financially responsible for legal costs represent a significant portion of the respirator market. In addition, as a result of the arrangements involving these lawsuits and claims, the Company has only a portion of the liability in any given case. When the Company disposed of the business in 1995 to Aearo Corporation ("Aearo"), it agreed with Aearo that for an annual fee of $400,000, the Company would retain responsibility for, and indemnify Aearo against, claims asserted after July 11, 1995 to the extent they are attributable to the use of respirators sold before that date. Aearo can discontinue payment of the fee at any time, in which case it will assume the responsibility for and indemnify the Company with respect to these claims. Since the divestiture and until fiscal 2001, the Company had never spent more than the $400,000 that it collects from Aearo each year. During the third quarter, the Company agreed to pay up to $2 million as its contribution toward a settlement involving up to 13,000 claimants in Mississippi. The Company expects to pay this amount over the next eighteen months. As of the beginning of calendar year 2002, there were approximately 28,000 claimants in pending cases asserting claims against American Optical in connection with respirators. As of June 30, 2002 there were approximately 38,000 claimants, which total includes a substantial portion of the claims in the Mississippi settlement. Under the present allocation arrangements, as claims are settled, Cabot would expect to contribute toward settlement of a significant percentage, but not all, of these claims. As a result of the Mississippi settlement and the rate of new claims which have been filed during the year, the Company has recorded a charge of $5 million during the current quarter bringing its total reserve for respirator matters to $6 million. In estimating its liability, the Company made the following assumptions: (i) that future settlements would continue at the historical rate of $320 per claimant; (ii) while the actual number of claims for which Cabot contributes depends upon a number of factors, that Cabot will continue to be responsible for well over half of the total claims and (iii) that a significant number of the outstanding claims are included in the Mississippi settlement. This amount represents Cabot's best estimate of the liability it will incur in connection with the settlement of pending respirator claims. Cabot is unable to determine a range of liabilities for the pending claims, however, because there is uncertainty in the possible outcome of the cases. Because this is a very unpredictable area, Cabot is unable to estimate the number of future claims or the range of liability that may be incurred as a result of such claims on any reasonable basis. As a result, the Company has not reserved for future claims at this time. While in any given quarter the impact of these actions may be significant, Cabot continues to believe that this issue will not have a material impact on the Company's financial condition. On July 29, 2002, a complaint involving a supply agreement between Cabot and AVX, one of Cabot's tantalum customers, was filed in U.S. District Court in Massachusetts by AVX Corporation. The complaint alleges unfair and deceptive trade practices, breach of contract and other related matters. Cabot believes that AVX's complaint is not meritorious and that Cabot has valid defenses, which it intends to assert vigorously. AVX has indicated, however, that it intends to continue to purchase product under the supply agreement with Cabot. As of June 30, 2002, Cabot has approximately $27 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 -14-

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. H. COMMON TREASURY STOCK Common treasury stock is presented on the consolidated balance sheet at cost as a reduction to stockholders' equity. During the nine months ended June 30, 2002, Cabot repurchased $52 million of its common stock of which $46 million was retired and $6 million will be held in treasury. This common stock held in treasury will be used to fund an employee benefit plan. -15-

CABOT CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -(Continued) June 30, 2002 (In millions, except per share amounts) UNAUDITED M. RECENT ACCOUNTING DEVELOPMENTS The Financial Accounting Standards Board (FASB) issued FAS No. 143, "Accounting for Obligations Associated with the Retirement of Long-lived Assets", in June 2001. The objective of FAS No. 143 is to establish an accounting standard for the recognition and measurement of an asset retirement obligation on certain long-lived assets. The retirement obligation must be one that results from the acquisition, construction or normal operation of a long-lived asset. FAS No. 143 requires the legal obligation associated with the retirement of a tangible long-lived asset to be recognized at fair value as a liability when incurred, and the cost to be capitalized by increasing the carrying amount of the related long-lived asset. FAS No. 143 will be effective for Cabot on October 1, 2002. Cabot is currently evaluating the effect of implementing FAS No. 143. In October 2001, the FASB issued FAS No. 144, "Accounting for the Impairment or Disposal of Long-lived Assets", which supersedes FAS No. 121, "Accounting for the Impairment of Long-lived Assets and for Long-lived Assets to be Disposed of" and provisions of APB Opinion No. 30 "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions", for the disposal of segments of a business. The statement creates one accounting model, based on the framework established in FAS No. 121, to be applied to all long-lived assets including discontinued operations. FAS No. 144 will be effective for Cabot on October 1, 2002. Cabot is currently evaluating the effect of implementing FAS No. 144. The FASB issued FAS No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections", in April 2002. This statement updates, clarifies and simplifies existing accounting pronouncements. Specifically, the statement rescinds FAS No. 4, "Reporting Gains and Losses from Extinguishment of Debt", FAS No. 64, "Extinguishment of Debt Made to Satisfy Sinking Fund Requirements" and FAS No. 44, "Accounting for Intangible Assets of Motor Carriers." This statement amends FAS No. 13, "Accounting for Leases" and certain other existing authoritative pronouncements to make technical corrections or clarifications. FAS No. 145 will be effective for Cabot related to the rescission of FAS No. 4 and FAS No. 64 on October 1, 2002. FAS No. 145 is effective related to the amendment of FAS No. 13 for all transactions occurring after May 15, 2002. All other provisions of FAS No. 145 are effective for financial statements issued after May 15, 2002. Cabot is currently evaluating the effect of implementing FAS No. 145. In July 2002, the FASB issued FAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities", which nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." FAS 146 requires a liability for a cost associated with an exit or disposal activity to be recognized and measured initially at its fair value in the period in which the liability is incurred. If fair value cannot be reasonably estimated, the liability shall be recognized initially in the period in which fair value can be reasonably estimated. In periods subsequent to the initial measurement, changes to the liability resulting from revisions to either the timing or the amount of estimated cash flows must be recognized as adjustments to the liability in the period of the change. The provisions of FAS 146 will be effective for the Company prospectively for exit or disposal activities initiated after December 31, 2002. Cabot is in the process of assessing the impact of FAS 146 on its consolidated financial statements. -24-

CABOT CORPORATION ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS I. CRITICAL ACCOUNTING POLICIES Critical accounting policies are those that are central to the presentation of the Company's financial condition and results of operations and that require subjective or complex estimates by management. The preparation of the Company's financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its policies and estimates, including those related to revenue recognition and accounts receivable, inventory valuation, the valuation of long-lived assets, environmental costs, pensions and other post-employment benefits, and litigation and contingencies. The Company bases its estimates on historical experience, current conditions and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE The Company derives its revenue through the sale of chemical products, performance materials and specialty fluids products. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectibility is probable. Revenue from product sales is recognized when product is shipped and title and risk of loss has passed to the customer. The Company generally is able to ensure that products meet customer specification prior to shipment. The Company prepares its estimates for sales returns and allowances, discounts, and rebates quarterly based primarily on historical experience updated for changes in facts and circumstances, as appropriate. If actual future results vary, the Company may need to adjust its estimates, which could have an impact on earnings in the period of adjustment. The Company's revenue recognition policies are in compliance with Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB 101"), which establishes criteria which must be satisfied before revenue is realized or realizable and earned. The Company maintains allowances for doubtful accounts for estimated losses resulting from the potential inability of its customers to make required payments. If the financial condition of the Company's customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required, which could affect future earnings. As of June 30, 2002, the allowance for doubtful accounts was $5 million. INVENTORY VALUATION The cost of most raw materials, work in process, and finished goods inventories in the United States is determined by the last-in, first-out ("LIFO") method. The cost of other United States and all non-United States inventories is determined using the average cost method or the first-in, first-out ("FIFO") method. As of June 30, 2002, inventories valued on the FIFO basis would have been $84 million higher than the LIFO value of these inventories. In cases where the market value of inventories is below cost, the inventory is stated at market value. The Company writes down its inventories for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. Such write-downs have not historically been significant. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. -25-

VALUATION OF LONG-LIVED ASSETS The Company's long-lived assets include property, plant, equipment, long-term investments, goodwill and other intangible assets. The Company reviews the carrying values of long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized when the fair value of the asset is less than the carrying value of the asset. The fair value of long-lived assets, other than goodwill, is based on undiscounted estimated cash flows. The Company's estimates reflect management's assumptions about selling prices, production and sales volume, costs, and market conditions over the estimated remaining operating period. If an impairment is indicated, the asset is written down to fair value. From time to time, the Company may decide to abandon a fixed asset project, plant expansion or other long-lived asset initiative in which case an impairment loss is recognized if the carrying value of the asset exceeds its salvage value. The Company records this impairment charge in the period in which it commits to a plan to abandon the asset. Effective October 1, 2001, the Company adopted FAS No. 142, "Goodwill and Other Intangible Assets." In accordance with FAS No. 142, the Company no longer amortizes goodwill and indefinite lived intangible assets. The Company performs an annual impairment test for goodwill by comparing the fair value of each reporting unit to its carrying value, including goodwill. The fair value is based on discounted estimated cash flows. The assumptions used to estimate the fair value of a reporting unit include management's best estimates of the reporting unit's future growth rates, capital expenditures, discount rates, and market conditions over the estimated remaining operating period. If the carrying value exceeds the fair value, then the Company compares the implied fair value of the reporting unit's goodwill with the carrying value of the goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to all of the assets and liabilities of that reporting unit. If the carrying amount exceeds the implied fair value of the goodwill, then an impairment loss is recognized for the excess amount. As required by FAS No. 142, impairment tests will be performed at least annually. During the third quarter of fiscal 2002, Cabot performed the fiscal 2002 impairment test and determined that no impairment loss should be recognized. ENVIRONMENTAL COSTS The Company accrues environmental costs when it is probable that the Company has incurred a liability and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated, but a range of estimated liability can be reasonably estimated, the Company accrues the amount that reflects its best estimate within that range. The amount accrued reflects the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties. The availability of new information, changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in applicable government laws and regulations could result in higher or lower costs. The Company does not reduce its estimated liability for possible recoveries from insurance carriers. As of June 30, 2002, the Company had $27 million reserved for environmental matters. PENSIONS AND OTHER POST-EMPLOYMENT BENEFITS The Company maintains both defined benefit and defined contribution plans for its employees. In addition, the Company provides certain health care and life insurance benefits for retired employees. The costs and obligations related to these benefits reflect the Company's assumptions related to general economic conditions, including interest rates, expected return on plan assets, and rate of compensation increase for employees. Projected health care benefits reflect the Company's assumptions about health care cost trends. The cost of providing plan benefits also depends on demographic assumptions including retirements, mortality, turnover, and plan participation. If actual experience differs from these assumptions, the cost of providing these benefits could increase or decrease. Actual results that differ from the assumptions are accumulated and amortized over future periods and therefore affect the recognized expense and recorded obligation in such future periods. -26-

LITIGATION AND CONTINGENCIES When the Company is involved in litigation, the Company accrues a liability for such matters when it is probable that a liability will be incurred and the amount can be reasonably estimated. The estimated reserves are recorded based on the Company's best estimate of the liability associated with such matters or the low end of the estimated range of liability if the Company is unable to identify a better estimate within that range. However, there is always the possibility of an unusual result in any particular case that may have an adverse effect on the results of operations. During the quarter ended June 30, 2002, Cabot increased its reserve for respirator claims by $5 million. II. RESULTS OF OPERATIONS Net sales and operating profit before taxes by segment are shown in Note L of the consolidated financial statements. THREE MONTHS ENDED JUNE 30, 2002 VERSUS THREE MONTHS ENDED JUNE 30, 2001 Net income for the third quarter of fiscal 2002 was $19 million ($0.28 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 were special charges totaling $7 million ($0.07 per diluted common share) of which $5 million was a charge to increase Cabot's reserve for respirator claims derived from a disposed safety products business, $3 million was an asset impairment charge for the cancellation of expansion projects at the Performance Materials plant in Boyertown, Pennsylvania related to the acquisition of Showa Cabot Supermetals KK, which we now call Cabot Supermetals ("CSM") , and $1 million was a benefit from insurance recoveries. In addition, third quarter 2002 earnings were favorably impacted by a $1 million ($0.01 per diluted common share) benefit from an insurance recovery related to the discontinued liquified natural gas ("LNG") business. Included in results for the third quarter of 2001 were special charges totaling $4 million ($0.04 per diluted common share) 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. As noted above, included in the special items charges of $0.07 during the third quarter of 2002 was a $0.05 charge to increase Cabot's reserve for respirator claims. These claims derive from a safety products business that Cabot owned and operated from 1990 to 1995, at which point the business was sold in a leveraged de-consolidation to Aearo Corporation. Cabot continues to own 42.5% of Aearo. The number of respirator cases has increased over the last 18 months, while the cost per claim has remained stable. At the end of June 2002, there were approximately 38,000 respirator claims outstanding against the historical manufacturer of the products. The actual number of claims for which Cabot contributes depends upon a number of factors, but has historically been well over half of the total claims. Cabot's contribution level for settlement has averaged approximately $320 per claimant. In June 2002, Cabot reached agreement to contribute to the settlement of up to 13,000 claims in Mississippi at a total cost not to exceed $2 million. It is anticipated that a significant number of the 13,000 settled claims are respirator related and are therefore included in the 38,000 above mentioned outstanding respirator cases. The $5 million charge recorded in the third quarter of 2002 includes the Mississippi settlement as well as Cabot's best estimate, based on experience to date, of the Company's potential liability for all other pending respirator related claims as of June 30, 2002. Because this is a very unpredictable area, Cabot is unable to estimate the number of future claims or the range of liability that may be incurred as a result of such claims on any reasonable basis and therefore has not reserved for them at this time. While in any given quarter the impact of these actions may be significant, Cabot continues to believe that this issue will not have a material impact on the Company's financial condition. Sales decreased $46 million or 11%, from $436 million last year to $390 million this year. Similarly, profit before taxes and special items from continuing operations decreased 40% from $50 million in the third quarter of fiscal 2001 to $30 million in the third quarter of fiscal 2002. Sales for the Chemical Businesses decreased 3%, from $336 million in the third quarter of fiscal 2001 to $326 million in the third quarter of fiscal 2002. Operating profit decreased 10%, from $30 million to $27 million. The decrease was principally driven by reduced margins in the carbon black business due to contract related pricing -27-

adjustments. However, the carbon black and fumed metal oxides businesses did experience higher volumes both sequentially and year over year, which offset some of the margin decline. Carbon black volumes increased in all regions year over year. The Company is cautiously optimistic that the carbon black business may be recovering from the bottom of the cycle. Globally, volumes increased 7% in the third quarter of fiscal 2002 as compared to the same period last year. In North America, greater market demand, particularly for rubber blacks, resulted in an 11% increase in volumes for the carbon black business. Strong demand in Brazil resulted in an 8% increase in volumes in South America. Increased demand in Asia Pacific, particularly in China, resulted in a 7% increase in volumes and stable demand in Europe resulted in a 3% increase in volumes in that region. However, reduced margins caused by contract related pricing adjustments significantly impacted profitability, particularly in North America. The effect of foreign exchange rates had a minimal impact on the profitability of the carbon black business in the third quarter of 2002 compared to the same quarter of 2001. The fumed metal oxides business experienced a 10% increase in volumes in the third fiscal quarter of 2002 compared to the same quarter of 2001. In particular, the business experienced improved demand in both the electronics markets and the traditional silicone rubber, composites and adhesives markets year over year. In addition, the niche markets experienced improved year over year volumes which were offset by price erosion. Operating profit for the business remained flat as compared to the third quarter of 2001 as the impact of increased volumes was reduced by approximately $3 million in asset impairment write-offs. The inkjet colorants business continues to make progress with the growth of its existing commercial products and the development of new products. Higher sales to both OEMs and niche customers (aftermarket sales) resulted in a 46% increase in volumes and a $1 million increase in operating profit in the third quarter of fiscal 2002 versus the third fiscal quarter of 2001. The Chemical Businesses showed significant signs of recovery with strong volumes during much of the third quarter of 2002. Volumes increased 7% on both a year over year and sequential basis. However, in the month of June 2002 carbon black volumes declined to 2001 levels resulting in a cautious outlook for the coming months. Cabot's fourth quarter is traditionally its weakest quarter due to seasonal vacations and customer shutdowns. Consequently, the Company remains cautious about the outlook for the Chemical Businesses segment for the rest of fiscal 2002. Performance Materials sales decreased 34% from $99 million in the third quarter of fiscal 2001 to $65 million in the third quarter of fiscal 2002. Volumes and operating profit declined 60% and 68%, respectively, due to customer contract disputes and slower market conditions. As a result, the tantalum business experienced a $21 million decline in operating profit versus the year ago quarter. However, the business experienced improved margins as the result of higher average selling prices and lower average ore costs due to a decline in spot ore prices. During the quarter, Cabot was able to successfully resolve the contract dispute with one of its customers, Vishay. In exchange for volume and price concessions, Vishay extended one of their contracts and agreed to purchase tantalum products at regular intervals throughout the terms of the contracts beginning late in the third quarter of fiscal 2002. At June 30, 2002, litigation was ongoing with another tantalum customer, Kemet. Subsequent to the third fiscal quarter of 2002, on July 29, 2002, a complaint involving a supply agreement between Cabot and AVX, one of Cabot's tantalum customers, was filed in U.S. District Court in Massachusetts by AVX Corporation. The complaint alleges unfair and deceptive trade practices, breach of contract, and other related matters. Cabot believes that AVX's complaint is not meritorious and that Cabot has valid defenses, which it intends to assert vigorously. AVX has indicated, however, that it intends to continue to purchase product under the supply agreement with Cabot. As these legal matters continue, the Company remains cautious about the outlook for the fiscal year for this business. Specialty Fluids sales in the third quarter were $5 million versus $6 million last year. The segment reported an operating loss of $1 million for the third quarter of 2002 and 2001. While the business benefited from improved pricing for cesium formate in the third quarter of 2002, volumes decreased due to the smaller size of the completion jobs undertaken during the quarter. During the third quarter of fiscal 2002, Specialty Fluids finalized work on one drill-in and five additional completion jobs. To date, cesium formate has been successfully used in a total of 56 operations, 49 completions and 7 drill-ins, primarily involving challenging high pressure, high temperature wells in the North Sea. In the third quarter of fiscal 2002, hydrocarbon production rates continued to support the initial flow -28-

tests from drill-in jobs finished during the fourth quarter of fiscal 2001. These results indicate that cesium formate is delivering the value in use that the Company and our customers anticipated. Research and technical service spending and selling and administrative expenses remained flat at $12 million and $55 million, respectively, for the third quarter of 2002 versus the third quarter of last year. Interest and dividend income in the third quarter was $4 million less than in the same quarter last year due to a decrease in Cabot's cash position and lower interest rates. Interest expense for the quarter ended June 30, 2002 decreased $1 million versus the year ago quarter due to the benefit of lower interest rates on the Company's variable rate debt and capitalized interest on two significant projects. In the third quarter of 2002, other income increased $5 million, largely due to a $2 million foreign exchange gain, primarily resulting from a net U.S. dollar receivable position in Argentina and $1 million in income related to the demutualization of Prudential Life Insurance Company. 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 38 employees of the Chemical and Performance Materials businesses, $7 million for facility closing costs, and a $9 million charge for the impairment of long-lived assets. One of the plant closures was completed during fiscal 2001 and the second plant closure was completed during the second quarter of fiscal 2002. As of June 30, 2002, all severance and termination benefits had been paid and $2 million remained accrued for the required monitoring costs at the second site. NINE MONTHS ENDED JUNE 30, 2002 VERSUS NINE MONTHS ENDED JUNE 30, 2001 Net income for the first nine months of fiscal 2002 was $84 million ($1.17 per diluted common share) compared to $96 million ($1.28 per diluted common share) for the first nine months of fiscal 2001. Included in the results from operations for the first nine months of 2002 were special charges totaling $10 million ($0.10 per diluted common share) of which $6 million was an asset impairment charge related to the cancellation of expansion projects in the Performance Materials plant in Boyertown, Pennsylvania and non-capitalizable transaction costs, both associated with the acquisition of CSM. Also included was a $5 million charge to increase Cabot's reserve for respirator claims and a $1 million benefit related to insurance recoveries. In addition, third quarter 2002 earnings were favorably impacted by a $1 million ($0.01 per diluted common share) benefit from an insurance recovery related to the discontinued LNG business. Included in the results from operations for the first nine months of fiscal 2001 were special charges of $21 million ($0.20 per diluted common share) related to the retirement of Cabot's Chief Executive Officer and the resignation of Cabot's Chief Financial Officer. In addition, third quarter 2001 earnings were favorably impacted by $3 million ($0.04 per diluted common share) of additional proceeds from the September 2000 sale of the LNG business. Sales decreased 13% from $1,289 million last year to $1,117 million this year due to somewhat weaker volumes and pricing in the Chemical Businesses and significantly decreased volumes in the Performance Materials segment. Profit before taxes and special items decreased 11% from $138 million in the first nine months of fiscal 2001 to $123 million in the first nine months of fiscal 2002. Sales for the Chemical Businesses decreased $107 million or 10%, from $1,027 million last year to $920 million this year. Operating profit decreased $22 million or 21%, from $106 million to $84 million. The decrease in profitability is primarily attributed to slower industrial growth in North America and Europe, a decline in margins, and unfavorable currency trends. -29-

Performance Materials sales were $195 million, a 24% decrease from $257 million in the first nine months of fiscal 2001. Operating profit increased 4% from $53 million in the first nine months of last year to $55 million in the first three quarters of this year driven by higher prices and lower raw material costs, largely offset by lower volumes. Specialty Fluids realized a $1 million improvement in sales for the nine month period ended June 30, 2002. Sales increased from $19 million last year to $20 million this year. Specialty Fluids reported a $1 million operating loss for both the nine month period of 2002 and the same period in 2001. While cesium formate volumes and pricing improved, the business's performance was negatively impacted by declining results in its mined minerals sector. Research and technical service spending remained flat at $35 million for the first nine months of 2002 versus the same period of last year. Selling and administrative expenses increased $2 million from $152 million for the first nine months of fiscal 2001 to $154 million spent in the first nine months of this year. The increase is largely due to increased administrative costs offset by reduced stock-based incentive compensation costs. Interest and dividend income in the nine months ended June 30, 2002 was $16 million less than in the same period last year due to a decrease in Cabot's cash position. Lower interest rates further negatively impacted interest income. Interest expense for the first nine months of fiscal 2002 decreased $4 million versus the year ago period due to the benefit of lower interest rates on the Company's variable rate debt and capitalized interest on two significant projects. In the nine month period ended June 30, 2002, other income increased $9 million, largely due to a $3 million foreign exchange gain, primarily resulting from a net U.S. dollar receivable position in Argentina, a $2 million gain from the sale of Cabot Microelectronics shares related to incentive compensation forfeitures, and $1 million in income related to the demutualization of Prudential Life Insurance Company. 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 38 employees of the Chemical and Performance Materials businesses, $7 million for facility closing costs, and a $9 million charge for the impairment of long-lived assets. One of the plant closures was completed during fiscal 2001 and the second plant closure was completed during the second quarter of fiscal 2002. As of June 30, 2002, all severance and termination benefits had been paid and $2 million remained accrued for the required monitoring costs at the second site. Cabot is currently evaluating the viability of its tail gas engine project in the carbon black business and various courses of action are currently being identified, including the possibility of discontinuing the project in some locations. III. CASH FLOW AND LIQUIDITY During the first nine months of the fiscal year, cash provided by operating activities totaled $107 million as compared to cash used by operating activities of $44 million for the same period last year. The cash provided by operations for the first nine months of fiscal 2002 was higher than during the same period in 2001 due to a $178 million tax payment made in 2001 related to the September 2000 disposition of Cabot's LNG business. Capital spending for the first nine months of the year was $201 million. Of this amount, $89 million, net of $10 million in cash acquired, was related to the buyout by Cabot of the other 50% shareholder in the CSM joint venture. The majority of the remaining capital spending related to maintaining existing assets and the construction of a semi-works facility for the Nanogel(TM) business. Capital expenditures for 2002 are expected to be approximately $280 million. Capital expenditures for 2002 also include replacement projects, plant expansions, and the completion of projects started in fiscal 2001. On February 8, 2002, Cabot purchased the remaining 50% of the shares of CSM in Japan, from its joint venture partner, Showa Denko KK. CSM is a supplier of tantalum powders and metal products to the global electronics, -30-

aerospace, and chemical processing industries. The acquisition of CSM expands the production capacity and performance capability of Cabot's tantalum business. Cash used by financing activities was $93 million in the first nine months of fiscal 2002 as compared to $135 million for the same period last year. In the first nine months of 2002, the Company primarily used cash for the repurchase of $52 million of its common stock and $5 million of its preferred stock, $26 million paid in the form of cash dividends to shareholders, and the repayment of short and long-term debt totaling $17 million. These uses of cash were somewhat offset by the issuance of $6 million of common stock, net of forfeitures. In the first nine months of 2001, the key components of the change in net cash from financing activities were the net 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. On May 10, 2002, Cabot's Board of Directors authorized the repurchase of up to 12.6 million shares of Cabot's common stock, superseding prior authorizations. As of June 30, 2002, approximately 8.4 million shares have been purchased under this authorization. As a result of lower cash balances and the acquisition of debt, both related to the CSM acquisition, Cabot's ratio of total debt (including short-term debt net of cash) to capital increased from 9% at September 30, 2001 to 27% at June 30, 2002. At June 30, 2002, the value of the Japanese yen based debt included in Cabot's consolidated financial results was $40 million of bank notes and $63 million of long-term debt. The bank notes are payable in Japanese yen and have renewable one year terms. Notes payable to banks are classified as current liabilities on the consolidated balance sheet. Interest rates are variable and based on short-term interest rates. The long-term debt is also payable in Japanese yen and matures on various dates in fiscal years 2004 to 2006. The interest rates on a portion of the loans are fixed and range from 1.5% to 2.1%. The interest rates on the remaining long-term loans are variable and based on short-term interest rates. Principal payments in each of the five fiscal years 2002 through 2006 are zero, zero, $11 million, $20 million, and $32 million, respectively. In July 2001, Cabot replaced its revolving credit facility with a new agreement. Under the new agreement, Cabot may, under certain conditions, borrow up to $250 million at floating rates. The new facility is available through July 13, 2006. As of June 30, 2002, Cabot was in compliance with all of its revolver debt covenants and 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. Maximum amounts and additional advances under some of CSM's loan agreements are subject to CSM's ongoing creditworthiness. As of June 30, 2002, Cabot was not aware of any credit concerns under CSM's loan agreements. On an ongoing basis, Cabot reviews its outstanding insurance claims, some of which relate to disposed and discontinued businesses, for potential recovery. Various amounts have been recovered in prior periods and Cabot anticipates receiving additional amounts in the fourth quarter and in future periods. In January 2002, the Securities and Exchange Commission released a "Commission Statement about Management's Discussion and Analysis of Financial Condition and Results of Operations" ("FR-61"). The release details the requirements for the Management's Discussion and Analysis section of the year-end and interim financial reports as they relate to liquidity, certain trading activities involving non-exchange traded contracts accounted for at fair value, and related party transactions. The Company discussed the market risks concerning liquidity and capital resources in the Form 10-K dated September 30, 2001 and has noted no other significant risks to the Company as of June 30, 2002. The Company is not involved in any transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of or requirements for capital resources. The Company is not involved in any trading activities involving commodity contracts that are accounted for at fair value. -31-

IV. RECENT ACCOUNTING DEVELOPMENTS Cabot is assessing the impact of the following new accounting pronouncements: The FASB issued Statement No. 143, "Accounting for Obligations Associated with the Retirement of Long-Lived Assets" ("FAS No. 143"), in June 2001. The objective of FAS No. 143 is to establish an accounting standard for the recognition and measurement of an asset retirement obligation on certain long-lived assets. The retirement obligation must be one that results from the acquisition, construction or normal operation of a long-lived asset. FAS No. 143 requires the legal obligation associated with the retirement of a tangible long-lived asset to be recognized at fair value as a liability when incurred, and the cost to be capitalized by increasing the carrying amount of the related long-lived asset. FAS No. 143 will be effective for Cabot on October 1, 2002. Cabot is currently evaluating the effect of implementing FAS No. 143. In October 2001, the FASB issued Statement No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("FAS No. 144"), which supersedes FAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of" and provisions of APB Opinion No. 30 "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions" ("APB No. 30"), for the disposal of segments of a business. The statement creates one accounting model, based on the framework established in FAS No. 121, to be applied to all long-lived assets including discontinued operations. FAS No. 144 will be effective for Cabot on October 1, 2002. Cabot is currently evaluating the effect of implementing FAS No. 144. The FASB issued Statement No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections" ("FAS No. 145") in April 2002. This statement updates, clarifies and simplifies existing accounting pronouncements. Specifically, the statement rescinds FASB Statement No. 4, "Reporting Gains and Losses from Extinguishment of Debt" ("FAS No. 4"), FASB Statement No. 64, "Extinguishment of Debt Made to Satisfy Sinking Fund Requirements" ("FAS No. 64") and FASB Statement No. 44, "Accounting for Intangible Assets of Motor Carriers." This statement amends FASB Statement No. 13, "Accounting for Leases" ("FAS No. 13") and certain other existing authoritative pronouncements to make technical corrections or clarifications. FAS No. 145 will be effective for Cabot related to the rescission of FAS No. 4 and FAS No. 64 on October 1, 2002. FAS No. 145 is effective related to the amendment of FAS No. 13 for all transactions occurring after May 15, 2002. All other provisions of FAS No. 145 are effective for financial statements issued after May 15, 2002. Cabot is currently evaluating the effect of implementing FAS No. 145. In July 2002, the FASB issued FAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities", which nullifies Emerging Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." FAS 146 requires a liability for a cost associated with an exit or disposal activity to be recognized and measured initially at its fair value in the period in which the liability is incurred. If fair value cannot be reasonably estimated, the liability shall be recognized initially in the period in which fair value can be reasonably estimated. In periods subsequent to the initial measurement, changes to the liability resulting from revisions to either the timing or the amount of estimated cash flows must be recognized as adjustments to the liability in the period of the change. The provisions of FAS 146 will be effective for the Company prospectively for exit or disposal activities initiated after December 31, 2002. Cabot is in the process of assessing the impact of FAS 146 on its consolidated financial statements. Forward-Looking Information: Included herein are statements relating to management's projections of future profits, the possible achievement of Cabot's financial goals and objectives, and management's expectations for Cabot's product development program. Actual results may differ materially from the results anticipated in the forward looking statements included herein due to a variety of factors, including but not limited to the following: market supply and demand conditions, fluctuations in currency exchange rates, the outcome of pending litigation, changes in the rate of economic growth in the United States and other major international economies, changes in regulatory environments, changes in trade, monetary and fiscal policies throughout the world, acts of war and terrorist activities, -32-

future litigation, cost of raw materials, patent rights of Cabot and others, demand for Cabot's customers' products, and competitors' reactions to market conditions. Timely commercialization of products under development by Cabot may be disrupted or delayed by technical difficulties, market acceptance, or competitors' new products, as well as difficulties in moving from the experimental stage to the production stage. The risk management discussion and the estimated amounts generated from the analyses are forward-looking statements of market risk, assuming certain adverse market conditions occur. Actual results in the future may differ materially from these projected results due to actual developments in the global financial markets. The methods used by Cabot to assess and mitigate risks should not be considered projections of future events or losses. The Company undertakes no obligation to publicly release any revisions to the forward-looking statements or reflect events or circumstances after the date of this document. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Cabot's objective in managing its exposure to interest rate changes is to maintain an appropriate balance of fixed and variable rate debt and to match borrowing costs with the economics of Cabot's business cycles. Cabot uses interest rate swaps to adjust fixed and variable rate debt positions. In October 2001, Cabot entered into four interest rate swaps in an aggregate notional amount of $97 million. The swaps are derivative instruments as defined by FAS No. 133 and have been designated as fair value hedges. The swaps hedge the change in the fair value of $97 million of Cabot's fixed rate medium term notes due to changes in interest rates. The interest rate swaps, as well as the medium term notes they hedge, mature on various dates through February 2007. The variable interest rates on the swaps reset every six months in June and December. As part of the CSM acquisition, the Company assumed debt denominated in Japanese yen of 14.05 billion yen. A portion of the debt, 9.45 billion yen, is at variable interest rates. Cabot also assumed interest rate swaps related to 5.7 billion yen of the variable rate debt. The swaps are variable-for-fixed swaps of the quarterly interest payments. The swaps require payment of fixed rates ranging from 1.5% to 2.2% and the receipt of variable rates. The swaps mature, along with the associated loans, in fiscal 2002 through 2006. The swaps are derivative instruments as defined by FAS No. 133 and have been designated as cash flow hedges. Cabot also has the equivalent of $148 million of Euro debt at variable rates. A change in rates of 10% on Cabot's aggregate variable rate debt could cause interest expense to change by $1 million per year. As of June 30, 2002, Cabot had $191 million in cash and short-term investments. It is the Company's practice to invest excess cash in instruments that will earn a high rate of return, consistent with the protection of principal. Interest income earned may vary as a result of changes in interest rates and average cash balances, which could fluctuate over time. Based on current market rates of 2% and a domestic cash balance invested in money market securities of $135 million, a 10% change in interest rates could cause interest income to change by approximately $0.3 million. Because of the global nature of its activities, Cabot has operations and facilities in many countries around the world. Major areas of functional currency exposure include the EURO, Japanese yen, British pound sterling, Canadian dollar, and Australian dollar. The Company's results are also exposed to currency fluctuations and devaluations in many developing countries throughout the world. Specifically, during the nine month period ended June 30, 2002, economic and political instability in Argentina and Brazil has led to larger than expected fluctuations in the exchange rates of those countries. The Argentina peso was devalued by more than 70% after the Government was forced to abandon its fixed exchange rate policy that pegged the value of the peso to the US dollar. The Brazilian real has recently weakened to record lows due to concerns related to the possible impact that the upcoming presidential election could have on the economy. The current depressed state of these functional currencies has resulted in a devaluation of the translated income statements for the quarter ended June 30, 2002. However, this was partly offset by the benefit of a net US dollar receivable position in these entities. The Company's Treasury function, under the guidance of a Risk Management Committee, continuously monitors foreign exchange exposures, so that Cabot can respond to changing economic and political environments and attempt to minimize the impact of adverse currency movements. -33-

CABOT CORPORATION PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS. The Company has exposure to a safety respiratory products business that it acquired in April 1990. It disposed of that business in July 1995. In connection with its acquisition of the business, the Company agreed, after an initial period during which responsibility was shared, to indemnify the seller, American Optical Corporation, ("American Optical"), for costs, including legal costs, settlements and judgments, in connection with a number of lawsuits and claims relating to the respirators (in exchange for which the Company received the benefits of the seller's insurance and other indemnities). These lawsuits and claims typically involve allegations that the plaintiffs suffer from asbestosis or silicosis as a result, in part, from respirators that were negligently designed or labeled. The defendants in these lawsuits are often numerous and include, in addition to respirator manufacturers, makers of asbestos and sand used in sand blasting. Neither the Company, nor its past or present subsidiaries, at any time manufactured asbestos or asbestos-containing products. Moreover, not every person with exposure to asbestos giving rise to an asbestos claim used a form of respiratory protection. At no time did the business for which the Company is financially responsible for legal costs represent a significant portion of the respirator market. In addition, as a result of the arrangements involving these lawsuits and claims, the Company has only a portion of the liability in any given case. When the Company disposed of the business in 1995 to Aearo Corporation ("Aearo"), it agreed with Aearo that for an annual fee of $400,000, the Company would retain responsibility for, and indemnify Aearo against, claims asserted after July 11, 1995 to the extent they are attributable to the use of respirators sold before that date. Aearo can discontinue payment of the fee at any time, in which case it will assume the responsibility for and indemnify the Company with respect to these claims. Since the divestiture and until fiscal 2001, the Company had never spent more than the $400,000 that it collects from Aearo each year. During the third quarter, the Company agreed to pay up to $2 million as its contribution toward a settlement involving up to 13,000 claimants in Mississippi. The Company expects to pay this amount over the next eighteen months. As of the beginning of calendar year 2002, there were approximately 28,000 claimants in pending cases asserting claims against American Optical in connection with respirators. As of June 30, 2002 there were approximately 38,000 claimants, which total includes a substantial portion of the claims in the Mississippi settlement. Under the present allocation arrangements, as claims are settled, Cabot would expect to contribute toward settlement of a significant percentage, but not all, of these claims. As a result of the Mississippi settlement and the rate of new claims which have been filed during the year, the Company has recorded a charge of $5 million during the current quarter bringing its total reserve for respirator matters to $6 million. In estimating its liability, the Company made the following assumptions: (i) that future settlements would continue at the historical rate of $320 per claimant; (ii) while the actual number of claims for which Cabot contributes depends upon a number of factors, that Cabot will continue to be responsible for well over half of the total claims and (iii) that a significant number of the outstanding claims are included in the Mississippi settlement. This amount represents Cabot's best estimate of the liability it will incur in connection with the settlement of pending respirator claims. Cabot is unable to determine a range of liabilities for the pending claims, however, because there is uncertainty in the possible outcome of the cases. -34-

Because this is a very unpredictable area, Cabot is unable to estimate the number of future claims or the range of liability that may be incurred as a result of such claims on any reasonable basis. As a result, the Company has not reserved for future claims at this time. While in any given quarter the impact of these actions may be significant, Cabot continues to believe that this issue will not have a material impact on the Company's financial condition. On July 29, 2002, a complaint involving a supply agreement between Cabot and AVX, one of Cabot's tantalum customers, was filed in U.S. District Court in Massachusetts by AVX Corporation. The complaint alleges unfair and deceptive trade practices, breach of contract and other related matters. The plaintiff seeks declaratory relief and unspecified damages. Cabot believes that AVX's complaint is not meritorious and that Cabot has valid defenses, which it intends to assert vigorously. ITEM 6. EXHIBITS AND REPORTS ON FORM 8-K.

The Rights Agent or any successor Rights Agent may resign and be discharged from its duties under this Agreement upon 30 days' notice in writing mailed to the Corporation and to each transfer agent of the Common Shares or Preferred Shares by registered or certified mail and to the holders of the Right Certificates by first-class mail. The Corporation may remove the Rights Agent or any successor Rights Agent upon 60 days' notice in writing, mailed to the Rights Agent or any successor Rights Agent, as the case may be, and to each transfer agent of the Common Shares or Preferred Shares by registered or certified mail, and to the holders of the Right Certificates by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Corporation shall appoint a successor to the Rights Agent. If the Corporation shall fail to make such appointment within a period of 60 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of a Right Certificate (who shall, with such notice, submit such holder's Right Certificate for inspection by the Corporation), then the registered holder of any Right Certificate may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a corporation or trust company organized and doing business under the laws of the United States, or of the State of New York or the Commonwealth of Massachusetts (or of any other state of the United States so long as such corporation is authorized to do business as a banking institution in the State of New York, or the Commonwealth of Massachusetts), in good standing, having a principal office in the State of New York or the Commonwealth of Massachusetts which is authorized under such laws to exercise corporate trust or stock transfer powers and is subject to supervision or examination by federal or state authority and which has individually or combined with an affiliate at the time of its appointment as Rights Agent a combined capital and surplus of at least $100 million dollars. After appointment, the successor Rights Agent shall be vested with the same powers,

rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment the Corporation shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares or Preferred Shares, and mail a notice thereof in writing to the registered holders of the Right Certificates. Failure to give any notice provided for in this Section 21, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be." 4. Except as amended hereby, the Agreement and all schedules or exhibits thereto shall remain in full force and effect. IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed in their names and on their behalf by and through their duly authorized officers, as of this 12th day of July, 2002.
