                               CABOT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               December 31, 1993


A.       SIGNIFICANT ACCOUNTING POLICIES

         Principles of Consolidation

         The consolidated financial statements include the accounts of Cabot
         Corporation and all majority-owned and controlled domestic and foreign
         subsidiaries.  Investments in majority-owned affiliates where control
         is temporary and investments in 20 percent-to 50 percent-owned
         affiliates are accounted for on the equity method.  All significant
         intercompany transactions have been eliminated.

         The 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 the Company's Form 10-K for the year ended
         September 30, 1993.

         The financial information submitted herewith is unaudited and reflects
         all adjustments which are, in the opinion of management, necessary to
         provide a fair statement of the results for the interim periods ended
         December 31, 1993 and 1992.  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.  During
         the fourth quarter of fiscal 1993, the Company adopted two new
         accounting standards related to postretirement benefits and income
         taxes.  Both of these standards were adopted as of October 1, 1992,
         and as a result, the quarter ending December 31, 1992 has been
         restated.

         Earnings Per Share

         The computation of fully diluted earnings per share considers the
         conversion of the Company's Series B ESOP Convertible Preferred Stock
         held by the Company's Employee Stock Ownership Plan, and also includes
         the potentially dilutive effects of the Company's Equity Incentive
         Plan.

B.       CONTINGENCIES

         The Company is a defendant in various lawsuits and is involved in
         other gas contract issues and environmental proceedings wherein
         substantial amounts are claimed.  In the opinion of the Company's
         management, these suits and claims should not result in final
         judgments or settlements which, in the aggregate, would have a
         material adverse effect on the Company's financial condition.

         Fumed silica supplied by Cabot was used by others in the manufacture
         of silicone breast implant envelopes.  There are currently pending
         more than 10,000 lawsuits in state and federal courts alleging
         injuries arising from the use of silicone breast implants.  The
         federal cases have been consolidated in the Multi-District Litigation
         pending in the United States District Court for the Northern District
         of Alabama.  Generally, the various state cases have been similarly
         consolidated in each jurisdiction.  In addition, arrangements have
         been made for consolidated discovery in all actions.  Cabot has been
         named as a defendant in fewer than 100 of those lawsuits, although
         additional lawsuits have been threatened and are expected to be
         brought in due course.  The pleadings in those suits are based on
         master form complaints adopted for use in the various jurisdictions.
         In each of the lawsuits brought against Cabot, Cabot is one of many
         defendants and the complaints do not allege the specific factual bases
         for liability against Cabot or the amount of damages specifically
         claimed against Cabot.  Cabot believes that it will be alleged that
         fumed silica supplied by Cabot contributed to the plaintiffs' injuries
         but also believes that it has adequate defenses.  However, the
         scientific, legal and societal issues raised by these cases are
         complex and the outcome is uncertain.  Cabot is still evaluating the
         litigation and therefore cannot predict with any assurance the course
         this litigation will take, the number of cases to which Cabot will be
         added as a defendant, the amount of damages, if any, that may be
         assessed against Cabot or the defense costs that will be incurred by
         Cabot.

                               CABOT CORPORATION

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations


I. RESULTS OF OPERATIONS

Sales and operating profit by industry segment are shown in the accompanying
table on page 11.

Three Months Ended December 31, 1993 versus
Three Months Ended December 31, 1992


Net income for the first quarter of fiscal year 1994 was $16.0 million ($0.79
per primary common share), compared with a loss of $14.2 million ($0.81 loss
per primary common share) in the same quarter a year ago.  Fiscal 1993 first
quarter results were restated to reflect a $26.1 million ($1.40 per share)
charge for required accounting changes.  Net income before these accounting
changes was $11.9 million ($0.59 per primary common share).  Net sales and
other operating revenues of $398.5 million were relatively flat with last
year's revenues of $396.1 million.  Total operating profit, however, increased
16% to $41.6 million from $35.9 million last year.

In the Specialty Chemicals and Materials Group, sales decreased 3% to
$278.2 million from $288.2 million, while operating profits increased 21% to
$36.0 million from $29.7 million in the first quarter of fiscal 1993.  Strong
operating profits reflected favorable margins in most of the Specialty
Chemicals businesses, and the effect of continued cost reductions.  The 
only significant shifts in Specialty Chemicals volumes were declines
in the European Carbon Black Division, partially offset by increases in the
South American Carbon Black Division and the Cab-O-Sil Division.  Regionally,
economic uncertainty continues in Europe and in Japan. The Company expects to
implement planned European capacity reduction with the closing of its carbon
black production facility in Hanau, Germany later this year.  The Company's
equity affiliate in Japan continues to review the possibility of carbon black
capacity reductions.

In the Energy Group, sales grew 11% to $120.3 million from $107.9 million, and
operating profits fell 10% to $5.6 million from $6.2 million last year.  The
decline in operating profits is a result of smaller margins in the Company's
LNG business brought about by an overall weakness in energy prices.  LNG prices
have recently rebounded with the unusually cold weather in the Northeast.  The
Company's LNG business imported 6 cargoes during the quarter versus 4 cargoes
last year.

First quarter net income also included a $1.7 million increase in the Company's
equity in affiliates.  This increase reflects performance improvement in
certain carbon black affiliate plants.

Interest expense declined 6% to $10.3 million from $11.0 million a year ago.
The improvement is a result of an overall reduction in debt from a year ago and
lower effective interest rates.

The Company's effective tax rate remained unchanged from last year at 40%.

The Company remains concerned that the European and Japanese economies are
still quite sluggish.  In Europe, carbon black volumes are down versus the year
ago quarter, and margins remain under pressure.  In the Energy Group, the
Company has recently experienced and expects to continue to experience some LNG
supply constraint due to the refurbishment of its Algerian supplier's LNG
facility.  The Company expects the positive effects of the cold winter in the
Northeast to offset the negative effects of the reduced shipments in the second
quarter.

II. CASH FLOWS AND LIQUIDITY

During the quarter, the Company's operations used $35 million of cash
reflecting increased working capital requirements due to normal seasonal trends
and the settlement of the last significant, and previously reserved for,
take-or-pay case.  Cabot increased its borrowings by $44.9 million during the
quarter primarily to fund these needs.

The Company invested $13 million in plant and equipment during the quarter.
The Company made no investments in its equity affiliates during this quarter
compared to $10.5 million in the first quarter of fiscal 1993.

At December 31, 1993, there were no amounts borrowed under a $250 million line
of credit available to the Company.  In January 1994, the company replaced this
existing line of credit with a new line, for the same amount, under similar
terms.  The Company's ratio of total debt (including short term debt net of
cash) to capital increased from 50% to 53% during the quarter.  The Company
believes its businesses can support higher-than-targeted leverage for an
interim period as a result of investment in businesses that will contribute
materially to the growth and stability of the Company's earnings.

Management expects cash from operations and present financing arrangements,
including the Company's unused line of credit, to be sufficient to meet the
Company's cash requirements for the foreseeable future.

                          Part II.  Other Information



Item 1.  Legal Proceedings

During the first quarter of fiscal year 1994, a take-or-pay case pending
against the Company and certain former subsidiaries and on appeal before the
court of appeals for the Seventh District of Texas was settled with no material
adverse effect on the Company's financial condition.  This case is in addition
to a take-or-pay case reported in the Company's Annual Report on Form 10-K to
have been settled in December 1993.

Fumed silica supplied by Cabot was used by others in the manufacture of
silicone breast implant envelopes.  There are currently pending more than
10,000 lawsuits in state and federal courts alleging injuries arising from the
use of silicone breast implants.  The federal cases have been consolidated in
the Multi-District Litigation pending in the United States District Court for
the Northern District of Alabama.  Generally, the various state cases have been
similarly consolidated in each jurisdiction.  In addition, arrangements have
been made for consolidated discovery in all actions.  Cabot has been named as a
defendant in fewer than 100 of those lawsuits, although additional lawsuits
have been threatened and are expected to be brought in due course.  The
pleadings in those suits are based on master form complaints adopted for use in
the various jurisdictions.  In each of the lawsuits brought against Cabot,
Cabot is one of many defendants and the complaints do not allege the specific
factual bases for liability against Cabot or the amount of damages specifically
claimed against Cabot.  Cabot believes that it will be alleged that fumed
silica supplied by Cabot contributed to the plaintiffs' injuries but also
believes that it has adequate defenses.  However, the scientific, legal and
societal issues raised by these cases are complex and the outcome is uncertain.
Cabot is still evaluating the litigation and therefore cannot predict with any
assurance the course this litigation will take, the number of cases to which
Cabot will be added as a defendant, the amount of damages, if any, that may be
assessed against Cabot or the defense costs that will be incurred by Cabot.
