         that section of the Code; provided, however, that the Committee shall
         have the discretion to cause the options granted in one or more
         Offering Periods under the Plan to be options to which Section 423 of

         aggregate four hundred seventy-five thousand (475,000) shares of the

         shares of Common Stock, treasury shares, or shares of Common Stock
         purchased by the Company or the Plan on an established stock exchange
         or a national market system.

4.02     Offerings. The Plan will be implemented by two annual offerings of the

                               PAYROLL DEDUCTIONS

5.01     Amount of Deduction. The form described in Section 3.03 will permit a
         participant to elect payroll deductions of any whole percentage from

5.02     Participant's Account. All payroll deductions made for a participant
         shall be credited to an account established for such participant under
         the Plan. A participant may not make any separate cash payment into

5.03     Changes in Payroll Deductions. A participant may reduce or increase
         future payroll deductions (within the limits described in Section 5.01)
         by filing with the Plan Representative a form provided by the Company
         for such purpose. The effective date of any increase or reduction in
         future payroll deductions will be the next following payroll period
         succeeding processing of the change form.

                               GRANTING OF OPTION

6.01     Number of Option Shares. On an Enrollment Date each participant shall
         be deemed to have been granted an option to purchase a number of shares
         of Common Stock determined by dividing the participant's accumulated
         payroll deductions on the Exercise Date by the lower of (i) 85% of the
         Fair Market Value of a share of Common Stock on the Enrollment Date or
         (ii) 85% of the Fair Market Value of a share of Common Stock on the
         Exercise Date; subject, however, to any applicable limitations
         contained in this Plan. In addition, the maximum number of shares a
         participant may purchase with respect to any Offering Period is that
         number of shares determined by dividing $12,500 by the Fair Market
         Value of a share of Common Stock on the Enrollment Date; provided,
         however, the maximum number of shares a participant may purchase with
         respect to the first Offering Period is that number of shares
         determined by dividing $25,000 by the Fair Market Value of a share of
         Common Stock on the Enrollment Date.


                                   ARTICLE VII
                               EXERCISE OF OPTION

7.01     Automatic Exercise. Subject to the next following sentence, each Plan
         participant's option for the purchase of stock with payroll deductions
         made during any Offering Period will be exercised automatically on the
         applicable Exercise Date for the purchase of the number of full and
         deemed fractional shares of Common Stock which the accumulated payroll
         deductions in the participant's account at the time will purchase at
         the Purchase Price (but not in excess of the maximum number of shares
         determined pursuant to Section 6.01), and any excess accumulated
         payroll deductions which, but for this limitation, would have been used
         to purchase shares, will be held




[CABOT MICROELECTRONICS CORPORATION LOGO]

         for the purchase of Common Stock on the next following Exercise Date
         without interest. The Committee shall have the discretion to reduce the
         number of shares of Common Stock to be purchased by participants with
         respect to an Offering Period and to allocate such reduced number of
         shares of Common Stock among participants in such Offering Period, so
         long as such reduction and allocation is done in a manner consistent
         with Section 423 of the Code. Any payroll deductions not applied to the
         purchase of shares of Common Stock by reason of the reduction pursuant
         to this Section 7.01 shall be promptly refunded to participants after
         the Exercise Date of the Offering Period to which such reduction
         applies.

7.02     Withdrawal of Account. No participant in the Plan shall be entitled to
         withdraw any amount from the accumulated payroll deductions in his or
         her account; provided, however, that a participant's accumulated
         payroll deductions shall be refunded to the participant as and to the
         extent specified in Section 8.01 below upon termination of such
         participant's participation in the Plan.

7.03     Fractional Shares. Fractional shares of Common Stock will not be issued
         under the Plan. Any deemed fractional share of Common Stock purchased
         by a Participant pursuant to Section 7.01 hereof will be combined with
         any deemed fractional shares purchased by the Participant in subsequent
         Offering Periods and whole shares of Common Stock then issued therefor.
         The Fair Market Value of all deemed fractional shares shall be paid in
         cash.

7.04     Exercise of Options. During a participant's lifetime, options held by
         such participant shall be exercisable only by such participant.

7.05     Delivery of Stock. As promptly as practicable after each Exercise Date,
         the Company will deliver to each participant the shares of Common Stock
         purchased upon exercise of such participant's option. The Company may
         deliver such shares in certificated or book entry form, at the
         Company's sole election.

                                  ARTICLE VIII
                                   WITHDRAWAL

8.01     In General. A participant may stop participating in the Plan at any
         time by giving written notice to the Plan Representative. Upon
         processing of any such written notice, no further payroll deductions
         will be made from the participant's Compensation during such Offering
         Period or thereafter, unless and until such participant elects to
         resume participation in the Plan by providing written notice to the
         Plan Representative pursuant to Section 3.03 above. Such participant's
         payroll deductions accumulated prior to processing of such notice shall
         be applied toward purchasing full and deemed fractional shares of
         Common Stock in the then-current Offering Period as provided in Section
         7.01 above unless the participant requests in writing to have the
         accumulated payroll deductions and cash in lieu of deemed fractional
         shares returned to him or her.

8.02     Effect on Subsequent Participation. A participant's withdrawal from any
         Offering Period will not have any effect upon such participant's
         eligibility to participate in any succeeding Offering Period or in any
         similar plan which may hereafter be adopted by the Company and for
         which such participant is otherwise eligible.

8.03     Termination of Employment. Upon termination of a participant's
         employment with the Company or any Designated Subsidiary Corporation
         (as the case may be) for any reason, including retirement but excluding
         death, the participant's payroll deductions accumulated prior to such
         termination, if any, shall be applied toward purchasing full and deemed
         fractional shares of Common Stock in the then-current Offering Period
         so long as the Exercise Date with respect to such Offering Period
         occurs on or within three months following such termination; provided,
         however, that (1) the participant may request in writing to have the
         accumulated payroll



[CABOT MICROELECTRONICS CORPORATION LOGO]

         deductions and cash in lieu of deemed fractional shares returned to him
         or her, and (2) upon termination of a participant's employment with the
         Company or any Designated Subsidiary Corporation (as the case may be)
         as a result of the participant's death, the participant's payroll
         deductions accumulated prior to such termination and cash in lieu of
         deemed fractional shares shall be paid to his or her estate.

                                   ARTICLE IX
                                    INTEREST

         paid into the Plan or credited to the account of or distributed to any
         participant.

10.01    Participant's Interest in Option Stock. No participant will have any
         interest in shares of Common Stock covered by any option held by such
         participant until such option has been exercised as provided in Section
         7.01 above.

10.02    Registration of Stock. Shares of Common Stock purchased by a
         participant under the Plan will be recorded in the name of the
         participant, or, if the participant so directs by written notice to the
         Plan Representative prior to the applicable Exercise Date, in the names
         of the participant and the participant's spouse as joint tenants with
         rights of survivorship or as tenants by the entireties, to the extent
         permitted by applicable law.

10.03    Restrictions on Exercise. The Board may, in its discretion, require as
         conditions to the exercise of any option that the shares of Common
         Stock reserved for issuance upon the exercise of such option shall have
         been duly listed, upon official notice of issuance, upon a stock
         exchange or market, and that either:


         10.03.1 a registration statement under the Securities Act of 1933, as
                 amended, with respect to said shares shall be effective, or

         10.03.2 the participant shall have represented at the time of purchase,
                 in form and substance satisfactory to the Company, that it is
                 his or her intention to purchase the shares for investment and
                 not for resale or distribution.

         or a Committee of members of the Board appointed by the Board. The
         Board or its Committee shall have full and exclusive discretionary
         authority to construe, interpret and apply the terms of the Plan, to
         determine eligibility and to adjudicate all disputed claims filed under
         the Plan. Every finding, decision and determination made by the Board

         the Committee shall have plenary authority in its discretion to
         interpret and construe any and all provisions of the Plan, to adopt

11.03    Rules Governing the Administration of the Committee. The Board may from
         time to time appoint members of the Committee in substitution for or in
         addition to members previously appointed and may fill vacancies,
         however caused, in the Committee. The Committee may select one of its
         members as its chairman, shall hold its meetings at such times and
         places as it shall deem advisable, and may hold telephonic meetings.
         All determinations of the Committee shall be made by a majority of its
         members. A decision or determination reduced to writing and signed by a
         majority of the members of the Committee shall be as fully effective as

         held. The Committee may appoint a secretary and shall make such rules
         and regulations for the conduct of its business as it shall deem

         communicated to participants in advance of any Offering Period to which
         they apply. Such rules and procedures may, in the discretion of the
         Committee, cause the options granted under any such Offering Period to
         be options to which Section 423 of the Code does not apply.

                              FOREIGN JURISDICTIONS


         Notwithstanding any other provision in this Plan, the Committee may
 adopt rules or procedures relating to the operation and administration of the
 Plan to accommodate the specific requirements of local laws and procedures.
 Without limiting the generality of the foregoing sentence, the Committee is
 specifically authorized to adopt rules and procedures regarding handling of
 payroll deductions, payment of interest, conversion of local currency, payroll
 tax, withholding procedures and handling of stock certificates which vary in
 accordance with the requirements of such local law and procedures. To the
 extent that any such rules or procedures are adopted with respect to options
 granted in an Offering Period to which Section 423 of the Code is intended to
 apply, the Committee shall cause such rules and procedures to be consistent
 with Section 423 of the Code.


                                  ARTICLE XIII
                                  MISCELLANEOUS

13.01    Transferability. Neither payroll deductions credited to any
         participant's account nor any option or other rights with regard to the
         exercise of an option to receive Common Stock under the Plan may be
         assigned, transferred, pledged, or otherwise disposed of in any way by
         the participant other than by will or the laws of descent and
         distribution. Any such attempted assignment, transfer, pledge or other
         disposition shall be without effect except that the Company may, in its
         discretion, treat such act as an election to withdraw from
         participation in the Plan in accordance with Section 8.01.

13.02    Use of Funds. All payroll deductions received or held by the Company
         under the Plan may be used by the Company for any corporate purpose.
         The Company shall not segregate such payroll deductions.

13.03    Adjustment Upon Changes in Capitalization; Change in Control.

         13.03.1 Changes in Capitalization. Subject to any required action by
                 the stockholders of the Company, the Reserves, the maximum
                 number of shares each participant may purchase per Offering
                 Period (pursuant to Section 6.01), as well as the Purchase
                 Price and the number of shares of Common Stock covered by each




[CABOT MICROELECTRONICS CORPORATION LOGO]

                 option under the Plan which has not yet been exercised shall be
                 proportionately adjusted for any Change in Capitalization. Such
                 adjustment shall be made by the Board, whose determination in
                 that respect shall be final, binding and conclusive. Except as
                 expressly provided herein, no issuance by the Company of shares
                 of stock of any class shall affect, and no adjustment by reason
                 thereof shall be made with respect to, the number or Purchase
                 Price of shares of Common Stock subject to an option.

         13.03.2 Change in Control. In the event of a Change in Control, the
                 Offering Period during which the Change in Control would
                 otherwise occur shall be accelerated and shall end on the last
                 payroll date immediately preceding the Change in Control.

13.04    Amendment or Termination. The Board shall have complete power and
         authority to terminate or amend the Plan; provided, however, that the
         Board shall not, without the approval of the shareholders of the
         Company, alter (i) the aggregate number of shares of Common Stock which
         may be issued under the Plan (except pursuant to Section 13.03 above),
         or (ii) the class of Employees eligible to receive options under the
         Plan, other than to designate Subsidiaries as Designated Subsidiary
         Corporations; and provided further, however, that, subject to Section
         13.05 no termination, modification, or amendment of the Plan may,
         without the consent of an Employee then having an option under the Plan
         to purchase shares of Common Stock, adversely affect the rights of such
         Employee under such option. In addition, and notwithstanding anything
         contained in this Plan to the contrary, to the extent necessary under
         Section 423 of the Internal Revenue Code (or any successor rule or
         provision or any applicable law or regulation), the Company shall
         obtain stockholder approval in such a manner and to such a degree as so
         required.

13.05    The Committee shall be entitled to change the Offering Periods, limit
         the frequency and/or number of changes in the amount withheld during an
         Offering Period, establish the exchange ratio applicable to amounts
         withheld in a currency other than U.S. dollars, permit payroll
         withholding in excess of the amount designated by a participant in
         order to adjust for delays or mistakes in the Company's processing of
         properly completed withholding elections, establish reasonable waiting
         and adjustment periods and/or accounting and crediting procedures to
         ensure that amounts applied toward the purchase of Common Stock for
         each participant properly correspond with amounts withheld from the
         participant's Compensation, and establish such other limitations or
         procedures as the Board (or its committee) determines in its sole
         discretion advisable which are consistent with the Plan, in each case
         so long as any such action is consistent with Section 423 of the Code.
         None of the foregoing actions shall be considered to have adversely
         affected any right of any participant.

13.06    In the event that the Committee determines that the ongoing operation
         of the Plan may result in unfavorable financial accounting
         consequences, the Committee may, in its discretion and, to the extent
         necessary or desirable, modify or amend the Plan to reduce or eliminate
         such accounting consequence including, but not limited to:

         13.06.1 changing the Purchase Price for any Offering Period including
                 an Offering Period underway at the time of the change in
                 Purchase Price;

         13.06.2 shortening any Offering Period so that the Offering Period ends
                 on a new Exercise Date, including an Offering Period underway
                 at the time of such action; and




[CABOT MICROELECTRONICS CORPORATION LOGO]

         13.06.3 allocating shares of Common Stock to participants pursuant to
                 Section 7.01 hereof.


         None of the foregoing actions shall be considered to have adversely
         affected any right of any participant.

13.07    Notices. All notices or other communications by a participant to the
         Company under or in connection with the Plan shall be deemed to have
         been duly given when received in the form specified by the Company by
         the Plan Representative.

13.08    Conditions Upon Issuance of Shares. Shares shall not be issued with
         respect to an option unless the exercise of such option and the
         issuance and delivery of such shares pursuant thereto shall comply with
         all applicable provisions of law, domestic or foreign, including,
         without limitation, the Securities Act of 1933, as amended, the
         Securities Exchange Act of 1934, as amended, the rules and regulations
         promulgated thereunder, and the requirements of any stock exchange upon
         which the shares may then be listed, and shall be further subject to
         the approval of counsel for the Company with respect to such
         compliance. As a condition to the exercise of an option, the Company
         may require the person exercising such option to represent and warrant
         at the time of any such exercise that the shares are being purchased
         only for investment and without any present intention to sell or
         distribute such shares if, in the opinion of counsel for the Company,
         such a representation is required by any of the aforementioned
         applicable provisions of law.

13.09    Effective Date. The Plan shall become effective as of its adoption by
         the Board, subject to approval by the holders of a majority of the
         shares of Common Stock, and shall continue in effect until the shares
         of Common Stock reserved for issuance under the Plan have been
         depleted, unless sooner terminated under Section 13.04 hereof. If the
         Plan is not so approved, the Plan shall not become effective.

13.10    No Employment Rights. The Plan does not, directly or indirectly, create
         in any person any right with respect to employment or continuation of
         employment by the Company or any Subsidiary, and it shall not be deemed
         to interfere in any way with the Company's or any Subsidiary's right to
         terminate, or otherwise modify, any Employee's employment at any time.

13.11    Effect of Plan. The provisions of the Plan shall, in accordance with
         its terms, be binding upon, and inure to the benefit of, all successors
         of each Employee participating in the Plan, including, without
         limitation, such Employee's estate and the executors, administrators or
         trustees thereof, heirs and legatees, and any receiver, trustee in
         bankruptcy or representative of creditors of such Employee.

13.12    Governing Law. The law of the State of Delaware will govern all matters
         relating to this Plan except to the extent superseded by the federal
         laws of the United States.
