Certain of the Shares have been acquired by the Selling Stockholders from the Company in transactions not involving a public offering within the meaning of Section 4(2) of the Securities Act of 1933 (the "1933 Act") pursuant to the Plan. The Selling Stockholders also may be deemed affiliates of the Company (as defined in Rule 405 of the 1933 Act). See "Principal and Selling Stockholders." The Company will not receive any of the proceeds from the sale of the Shares by the Selling Stockholders. Alternatively, the Shares may be sold from time to time in one or more transactions (which may involve one or more block transactions) on the New York Stock Exchange, the Pacific Stock Exchange or the Boston Stock Exchange, or in sales occurring in the public market of such Exchanges, in separately negotiated transactions, or in a combination of such transactions. Each sale may be made either at market prices prevailing at the time of such sale or at negotiated prices. Some or all of the Shares may be sold through brokers acting on behalf of each Selling Stockholder or to dealers for resale by such dealers. In connection with such sales, such brokers and dealers may receive compensation in the form of discounts or commissions from each Selling Stockholder and/or the purchasers of such Shares for whom they act as broker or agent (which discounts or commissions are not anticipated to exceed those customary in the types of transactions involved). All expenses of registration incurred in connection with this offering are being borne by the Company, but all brokerage commissions and other expenses incurred by each Selling Stockholder will be payable by such Selling Stockholder. See "Plan of Distribution." The Selling Stockholders and any dealer participating in the distribution of any Shares or any broker executing selling orders on behalf of the Selling Stockholders may be deemed to be "underwriters" within the meaning of the Act, in which case any profit on the sale of any or all of the Shares by the Selling Stockholders and any discounts or commissions received by any such brokers or dealers may be deemed to be underwriting discounts and commissions under the Act. The Company's Common Stock is listed on the New York Stock Exchange, the Pacific Stock Exchange and the Boston Stock Exchange under the trading symbol "CBT". The shares of Common Stock offered hereby are, or are expected to be, authorized for listing on such Exchanges.

THE COMPANY Cabot Corporation and its subsidiaries (the "Company") have businesses in specialty chemicals and materials and in energy. The Specialty Chemicals and Materials Group manufactures carbon black, fumed silica, thermoplastic concentrates and specialty compounds, and electronic materials and refractory metals. Carbon black is a very fine black powder used as a reinforcing agent in tires and industrial rubber products such as extruded profiles, hoses and molded goods. Special blacks are used to provide pigmentation, conductivity and ultraviolet protection and for other purposes in many specialty applications such as inks, plastics, cables and coatings. Fumed silica is an ultra-fine, high-purity silica used as a reinforcing, thickening, suspending or anti-caking agent in a wide variety of products for the automotive, construction and consumer industries, including adhesives, cosmetics, inks, lubricants, paints and pharmaceuticals. High-purity polishing compounds, made by the Company from fumed metal oxides and a variety of chemistries, are used in the manufacture of wafers, chips and other electronic devices by the semiconductor industry. The Company produces black and white thermoplastics concentrates and specialty compounds for sale to plastic resin producers and the plastics processing industry. The major applications for these materials include plastic pipe and tubing, plastic packaging and agricultural film, automotive components, cable sheathing and special packaging for use in the electronics industry. The Company also produces tantalum in various forms including powder, wire, sheet and foil for electrolytic capacitors. Both tantalum and niobium and their alloys are produced by the Company in wrought form for non-electronic applications such as chemical process equipment and the production of superalloys, and for various other industrial, defense, aerospace and medical applications. The Company maintained an approximately 42.5% ownership interest in Cabot Safety Corporation, after restructuring the Company's safety products and specialty composites business in July 1995. Cabot Safety Corporation manufactures and sells personal safety products, as well as energy absorbing, vibration damping and impact absorbing products for industrial noise control and environmental enhancement. The Company's principal executive offices are located at 75 State Street, Boston, MA 02109. The telephone number, including area code, of the Company's principal executive offices is (617) 345-0100. USE OF PROCEEDS The Company will not receive any of the proceeds from the sale of the Shares by the Selling Stockholders. -3- 7 PRINCIPAL AND SELLING STOCKHOLDERS The Selling Stockholders consist of non-employee directors of the Company. Any or all of the Shares listed below under the heading "Shares Offered" may be offered for sale by the Selling Stockholders pursuant hereto. Set forth below is the name of each Selling Stockholder, the number of shares of Common Stock beneficially owned by each Selling Stockholder as of the most recent practicable date, the number of shares of Common Stock that may be offered and sold by each Selling Stockholder hereunder and the number of shares of Common Stock to be owned by each Selling Stockholder if all Shares offered hereby by such Selling Stockholder are sold. There can be no assurances that any Selling Stockholder will sell all or any of the shares of Common Stock offered by him or her hereunder. Shares of Common Shares of Common Stock Owned Stock Owned as of After Name Shares Offered Offering ---- -------------- -------------- -------- Information regarding the sales of securities by the Selling Stockholders under the above headings will be provided herein by post-effective amendment at such time or times as one or more of the non-employee directors holding shares of Common Stock pursuant to the Company's Non-Employee Directors' Stock Compensation Plan (the "Plan") wish to avail themselves of this Prospectus. The Shares which may be offered from time to time pursuant hereto by the Selling Stockholders represent shares of Common Stock that were acquired by the Selling Stockholders under the Plan. Under the Plan, which became effective November 8, 1991, each non-employee director of the Company received initially 1,600 shares (after giving effect to various stock-splits). On January 15th in each year, commencing in 1997, each non-employee director will receive 1,600 shares of Common Stock (or a prorata number if the non-employee director is not standing for re-election) for service as a director previously rendered, and to be rendered. -4- 8 PLAN OF DISTRIBUTION Each Selling Stockholder may from time to time and subject to certain conditions effect sales of Shares earned by such Selling Stockholder under the Company's Plan. Such sales may be made in one or more transactions on the New York Stock Exchange ("NYSE") or the Pacific Stock Exchange or the Boston Stock Exchange or other securities exchanges or in the over-the-counter market or otherwise, at prices and at terms prevailing or at prices related to the then current market price, or in negotiated transactions, by gift or otherwise. If all or a portion of such shares are sold in transactions on the NYSE or the Pacific Stock Exchange or the Boston Stock Exchange, they may be sold by means of: (a) a block trade in which the broker or dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transactions; (b) purchases by a broker as principal and resale by such broker for its account pursuant to this Prospectus; (c) an Exchange distribution in accordance with the rules of such Exchange; (d) ordinary brokerage transactions and transactions in which the broker solicits purchasers; or (e) a combination of the foregoing methods. In effecting sales, brokers or dealers engaged by a Selling Stockholder may arrange for other brokers or dealers to participate. The brokers or dealers engaged by a Selling Stockholder may receive commissions or discounts from such Selling Stockholders in amounts to be negotiated prior to the sale. Such brokers or dealers and other participating brokers or dealers may be deemed to be "underwriters" within the meaning of the 1933 Act in connection with such sales. EXPERTS The consolidated balance sheets as of September 30, 1995 and 1994 and the consolidated statements of operations and cash flows for each of the three years in the period ended September 30, 1995, incorporated by reference in this Prospectus, have been incorporated by reference herein in reliance on the report of Coopers & Lybrand L.L.P., independent accountants, given on the authority of that firm as experts in accounting and auditing. The validity of the shares of Common Stock offered hereby is being passed upon for the Company by Robert Rothberg, Esq., Cabot Corporation, 75 State Street, Boston, Massachusetts 02109. Mr. Rothberg is a Vice President and the General Counsel of the Company. At the time of rendering his opinion as to the legality of the Common Stock being registered hereunder, Mr. Rothberg had a substantial interest in the Company, as defined by the rules of the Securities and Exchange Commission, in that Mr. Rothberg owned 83,294 shares of the Company's Common Stock, with a fair market value of in excess of $50,000, and had the right to purchase an additional 20,000 shares pursuant to the Company's 1996 Equity Incentive Plan.

Indemnification is also authorized with respect to any criminal action or proceeding where such person had no reasonable cause to believe his or her conduct was unlawful. The Company's current directors' and officers' insurance policies cover directors and officers of the Company and its subsidiaries. -6- 10 PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT Item 3.

The shares were issued to the Selling Stockholders pursuant to the Registrant's Non-Employee Directors' Stock Compensation Plan, a written plan in connection with the Selling Stockholders' service as outside directors for the Company. The Selling Stockholders had access, by virtue of their positions on the Company's Board of Directors, to sufficient information to make an informed investment decision. Item 8.

Item 9. Undertakings A. Subsequent Exchange Act Documents. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Page II-2 12 B. To Transmit Certain Material. The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus to each person to whom the prospectus is sent or given, a copy of the registrant's latest annual report to stockholders furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934. Where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, the undersigned also undertakes to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information. C. Undertaking to Update Annually. The undersigned registrant hereby undertakes: (1) to file during any period in which offers or sales are made, a post-effective amendment to the registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change in such information in the registration statement; (2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities shall be deemed to be the initial bona fide offering thereof; and (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. Provided, however, that if the information required to be included in a post-effective amendment by clauses (1)(i) and (1)(ii) of this paragraph is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, the registrant need not file a post-effective amendment to provide such information. D. Indemnification. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. Page II-3 13 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Boston, and the Commonwealth of Massachusetts, June XX, 1996.

June 21, 1996

Cabot Corporation
75 State Street
Boston, Massachusetts 02109

Ladies and Gentlemen:

      I am a Vice President and General Counsel of Cabot Corporation, a Delaware
corporation (the "Company"). In that capacity, I have acted as counsel for the
Company, with respect to the Company's Forms S-8 Registration Statement (the
"Registration Statement") to be filed by the Company with the Securities and
Exchange Commission in connection with the registration under the Securities Act
of 1933, as amended, by the Company of an aggregate of 400,000 shares of Common
Stock, par value $1.00 per share (the "Shares"), subject to purchase under the
Cabot Corporation Non-Employee Directors' Stock Compensation Plan (the "Plan").

      As counsel for the Company, I have examined, among other things, the
provisions of such applicable federal and state laws and certain corporate
records and proceedings, including the originals and/or copies of such
documents, certificates and records as I have deemed necessary and appropriate
in order to render this opinion.

      Based on the foregoing, I am of the opinion that the Shares have been duly
and validly authorized for issuance by all necessary corporate action on the
part of the Company and, upon delivery thereof and payment therefor in
accordance with the Plan and the Registration Statement, will be validly issued,
fully paid, and non-assessable.

      I consent to being named in the Registration Statement and related
prospectus as counsel who is passing upon the legality of the Shares. I also
consent to your filing copies of this opinion as an exhibit to the Registration
Statement.

                                    Very truly yours,

                                    /s/ Robert Rothberg

                                CABOT CORPORATION

                 NON-EMPLOYEE DIRECTORS' STOCK COMPENSATION PLAN





1.    Purpose.
      --------

      The purpose of the Cabot Corporation Non-Employee Directors' Stock
Compensation Plan (the "Plan") is to advance the interests of Cabot Corporation
and its stockholders by helping to attract and retain highly qualified,
non-employee directors. The Plan shall be interpreted and implemented in a
manner so that eligible Non-employee Directors will not fail, by reason of the
Plan or its implementation, to be "disinterested persons" within the meaning of
Rule 16(b)3 of the Securities Exchange Act of 1934, as such Rule and such Act
may be amended.


2.    Definition.
      -----------

      Unless the context clearly indicates otherwise, the following terms when
used in the Plan shall have the meanings set forth in this section:

      a.    "Board of Directors" shall mean the Board of Directors of the
             Company.

      b.    "Company" shall mean Cabot Corporation, a Delaware corporation,
             or its successor.

      c.    "Non-employee Directors" shall mean any member of the Board of
             Directors who is not also an employee of the Company or any of its 
             affiliates.

      d.    "Common Stock" shall mean the shares of common stock of the
             Company, $1 par value per share.


3.    Shares of Common Stock Subject to the Plan.
      -------------------------------------------

      Common Stock may be shares of the Company's authorized but unissued or
reacquired shares of Common Stock.


4.    Eligibility.
      ------------

      Only Non-employee Directors shall be eligible to receive shares of Common
Stock under the Plan.

5.    Awards of Common Stock.
      -----------------------

      On the date of the January meeting of the Board of Directors (or if no
such meeting is held, on January 15th) in each fiscal year of the Company, the
Company shall issue 400 shares of Common Stock to each Non-employee Director as
a portion of his or her annual compensation received as a Non-employee Director.
In the event the Director is first elected after the commencement of the fiscal
year, the shares issuable to him or her shall be prorated.


6.    Adjustments.
      ------------

      In the event of any reorganization, recapitalization, stock split, stock
dividend, combination of shares, merger, consolidation, issuance of rights or
any other change in the capital structure of the Company, the number of shares
of Common Stock to be issued hereunder shall be equitably adjusted to reflect
the occurrence of such event.


7.    General Provisions.
      -------------------

     a.    No Non-employee Director and no beneficiary or other person claiming
           under or through such Non-employee Director shall have any right,
           title or interest by reason of this Plan or any share of Common Stock
           to any particular assets of the Company. The Company shall not be
           required to establish any fund or make any other segregation of
           assets to assure the award of Common Stock hereunder.

     b.    No right under the Plan shall be subject to anticipation, sale,
           assignment, pledge, encumbrance or charge except by will or the law
           of descent and distribution.

     c.    Notwithstanding any other provision of the Plan or agreements made
           pursuant hereto, the Company shall not be required to issue or
           deliver any certificate for shares of Common Stock under this Plan
           prior to fulfillment of all of the following conditions:

            1.    Any required listing or approval upon notice of issuance of
                  such shares on any securities exchange on which the Common  
                  Stock may then be traded.
      

            2.    Any registration or other qualification of such shares under
                  any state or federal law or regulation or other qualification
                  which the Board of Directors shall upon the advice of counsel
                  deem necessary or advisable.

            3.    The obtaining of any other required consent or approval or
                  permit from any state or federal government agency.




                                   Page II-12

     d.   In no event shall the Company be required to issue a fractional share
          hereunder.

     e.   The issuance of shares to Non-employee Directors or to their legal
          representatives shall be subject to any applicable taxes or other laws
          or regulations of the United States of America or any state or
          commonwealth having jurisdiction thereover.


8.    Effective date; Termination and Amendment.
      ------------------------------------------

     a.   This Plan shall become effective on the date of its adoption by the
          Board of Directors provided, however, that any grants made under the
          Plan prior to its approval by the holders of a majority of the
          outstanding shares of Common Stock and Series B ESOP Convertible
          Preferred Stock of the Company voted either in person or by proxy at a
          duly held meeting of the stockholders of the Company shall be subject
          to such approval.

     b.   The Plan shall terminate on the date that occurs 20 years after its
          effective date. The Board of Directors may also terminate the Plan or
          make such modifications or amendments to the Plan as it may deem
          advisable, provided, however, that the Board of Directors may not
          amend the Plan:

          (1)  more often than once every six months, other than to comport with
               changes in the Internal Revenue Code, the Employee Retirement
               Income Security Act, or the rules thereunder; and

          (2)  without the affirmative vote of the holders of a majority of the
               outstanding shares of Common Stock and Series B ESOP Convertible
               Preferred Stock entitled to vote for any of the following 
               purposes:

               (i)   increase the maximum number of shares of Common Stock 
                     which may be awarded under the Plan

               (ii)  extend the period during which any shares of Common Stock
                     may be awarded;

               (iii) change the requirements as to the classes of persons
                     eligible to receive shares of Common Stock under the Plan;
                     or

               (iv)  make any other amendment to the Plan for which approval by
                     the stockholders of the Company is required pursuant to any
                     applicable law or rule.
