                         MEMC ELECTRONIC MATERIALS, INC.
                             STOCK OPTION AGREEMENT

                                     (Date)

(Name)
(Location)

     This letter describes the terms of the grant by MEMC Electronic Materials,
Inc. (the "Company") to you of nonqualified stock options (the "Options") to
purchase shares of the Company's Common Stock, par value $.01 per share (the
"Common Stock"), under the Company's 1995 Equity Incentive Plan, as amended and
restated effective December 6, 1999 (the "Plan"). The Company is granting these
Options to you in recognition of your valuable services to the Company and to
facilitate your participation in the Company's success.

     Capitalized terms used in this letter without definition shall have the
meanings assigned to them in the Plan. This letter, the Options and the Common
Stock issued upon the exercise of the Options shall be controlled by the terms
of the Plan, the terms of which are incorporated by reference into this letter.
In the event of any conflict or inconsistency between the Plan and this letter,
the Plan will govern.

     Before we describe how the Options work, it is important that you know that
none of the Options may be sold, transferred, assigned, pledged, or otherwise
encumbered or disposed of, except by will or the laws of descent and
distribution. Therefore, during your lifetime, an Option shall be exercisable
only by you or by your guardian or legal representative. Each permitted
transferee of an Option shall, as a condition of the transfer thereof, execute
an agreement pursuant to which it shall agree to comply with the terms of this
letter.

     1.   Grant of Options. You are hereby granted the number of Options shown
on Exhibit A, attached to this letter. These Options are effective as of (Date
of Grant), the "Date of Grant." Each such Option will entitle you to purchase
upon payment of the Exercise Price, one share of Common Stock. The decision to
use an Option to purchase a share of Common Stock will be referred to in this
letter as "exercising an option." The "Exercise Price" shall be the amount shown
on Exhibit A, which was the Fair Market Value, as defined in the Plan, of a
share of Common Stock on (Date of Grant).

     The Options granted pursuant to this letter shall be non-qualified stock
options, which are not qualified under Section 422 of the Code.

     2.   Terms and Conditions of Options. The Options granted under this letter
have the following terms and conditions:

          (a)  Vesting. Of the total number of Options granted to you by this
     letter, you will have the right to exercise 25% of them (i.e. 25% will
     vest) on the first anniversary of the Date of Grant and an additional 25%
     on each anniversary of the Date of Grant thereafter, such that by the
     fourth anniversary of the Date of Grant, you will have the right to
     exercise all (100%) of them (i.e. 100% will be vested). If a Change in
     Control occurs (except as the Compensation Committee of the Board of
     Directors of the Company (the "Committee"), as constituted immediately
     prior to such Change in Control, may otherwise determine in its sole
     discretion) any Options then outstanding (other than any Option granted
     within six months of such Change in Control) will become fully exercisable
     as of the date of the Change in Control.

          (b) Option Period. The Options will not be exercisable after the tenth
     anniversary of the Date of Grant, and may be subject to earlier termination
     as described below and in the Plan.

                                     Page 1


          Upon termination of your employment with the Company and its
     Subsidiaries for reasons other than your death, Disability or Retirement
     you (or your estate) may exercise any Option to the extent exercisable on
     the date of termination within the sixty day period after such a
     termination of employment (but never later than the tenth anniversary of
     the Date of Grant). Any Options which have not yet vested at the time of
     termination of your employment shall terminate and be cancelled (except as
     the Committee may otherwise determine in its sole discretion). Also, any
     Options not exercised within sixty days after such a termination of
     employment shall terminate and be cancelled.

          Upon termination of your employment with the Company and its
     Subsidiaries on account of your death, Disability or Retirement, all
     Options shall vest and you (or your Beneficiary) may exercise any or all
     Options within the three year period after such a termination of employment
     (but never later than the tenth anniversary of the Date of Grant);
     provided, however, that in the event of Retirement or Disability, no Option
     may be exercised until at least six months after its Date of Grant. From
     time to time, on a form acceptable to the Committee or its delegate, you
     may designate any person or persons (concurrently, contingently or
     successively) to whom the Options shall be transferred in the event that
     you die before you exercise the Options. A beneficiary designation form
     shall be effective only when the form is signed by you and filed in writing
     with the Company while you are alive, and shall cancel all beneficiary
     designation forms that you previously signed and filed. If no Beneficiary
     is so designated, your Beneficiary shall be the same as designated by you
     under the Company's group life insurance plan. If you have not designated a
     Beneficiary under the Company's group life insurance plan, your Beneficiary
     shall be your estate or the distributees thereof.

          For purposes of this paragraph, "Retirement" shall mean the
     termination of your employment with the Company after you attain sixty-five
     years of age, or after you attain fifty-five years of age and after
     completing 10 years of service.

          Notwithstanding anything to the contrary in this letter, in the event
     of your termination of employment with the Company and its Subsidiaries for
     Cause (as defined below), all Options, whether or not vested, shall be
     cancelled and no longer exercisable as of the date of such termination.

          Termination for "Cause" shall mean termination of your employment
     because of:

               (i)  any act or omission that constitutes a material breach of
          any of the material obligations of any employment agreement that you
          may have with the Company or any of its Subsidiaries (other than by
          reason of your death or Disability);

               (ii) the continued failure or refusal of you to perform the
          material duties required of you as an employee of the Company or any
          of its Subsidiaries (other than by reason of your death or
          Disability);

               (iii)  any willful material violation by you of any law or
          regulation applicable to the business of the Company or any of its
          Subsidiaries, or your conviction of a felony, or any willful
          perpetration by you of a common law fraud; or

               (iv) any other willful misconduct by you which is materially
          injurious to the financial condition or business reputation of, or is
          otherwise materially injurious to, the Company or any of its
          Subsidiaries.

                                     Page 2


          (c)  Exercising Options. You may exercise any or all vested Options by
     notifying the Company in writing that you wish to exercise your Options and
     accompanying the written notice (as described in paragraph 4 below) with
     the payment for the Common Stock you are purchasing with such Options.
     Payment must be equal to the total number of Options that you wish to
     exercise, multiplied by the Exercise Price.

          Payment may be made in cash, certified or bank check, note or other
     instrument acceptable to the Committee. Payment may also be made in full or
     in part in shares of Common Stock with a Fair Market Value (determined as
     of the date of exercise of such Option) at least equal to such full or
     partial payment. Common Stock used to pay the Exercise Price may be shares
     that you already own, or the Company may withhold shares of Common Stock
     that you would otherwise have received upon exercise of the Option. You
     also may exercise a Option through a "cashless exercise" procedure
     involving a broker or dealer approved by the Committee, provided that the
     conditions described in Section 8(f) of the Plan are satisfied.

          If you are subject to Section 16 of the Exchange Act, you shall have
     the unfettered right (but not the obligation) to pay the exercise price in
     full or in part in shares of Common Stock in accordance with Section 8(i)
     of the Plan.

          The date of exercise will be the date that all of the requirements
     above, as well as the requirements in 2(e) below, are met. No certificate
     showing the Common Stock purchased under such Option will be issued to you
     under 2(f) below until all of these requirements are met.

          (d)  Shareholder Rights. You will have no rights as a shareholder with
     respect to any shares of Common Stock purchased upon the exercise of an
     Option until a certificate or certificates for such shares is issued to you
     making you the "holder of record" of such shares. Other than under Sections
     13(b) and 13(c) of the Plan, no adjustment will be made for dividends or
     distributions or other rights related to any share for which the date of
     such dividend or distribution is prior to the date on which you will become
     the holder of record of the shares.

          (e)  Limitation on Exercise. Notwithstanding the other provisions of
     this letter, an Option shall not be exercisable unless and until (i) a
     registration statement under the Securities Act of 1933, as amended, has
     been duly filed and declared effective pertaining to the Common Stock
     subject to such Option and such Common Stock will have been qualified under
     applicable state "blue sky" laws, or (ii) the Committee in its sole
     discretion determines that such registration, qualification and status is
     not required as a result of the availability of an exemption from such
     registration, qualification, and status under such laws.

          (f)  Issuance of Certificate. As soon as practicable following the
     exercise of any Options, subject to the tax withholding provisions of
     Section 3(b), a certificate showing the number of shares of Common Stock
     issued in connection with such exercise will be issued in your name.

     3. Miscellaneous.

          (a)  No Rights to Grants or Continued Employment. You will not have
     any claim or right to receive future grants under the Plan. Nothing in the
     Plan or in this letter will give you any right to continued employment with
     the Company or any Subsidiary, as the case may be, or interfere in any way
     with the right of the Company or a Subsidiary to terminate your employment
     at any time, with or without cause.

          (b)  Tax Withholding. If the Company is required by any government

                                     Page 3


     entity to withhold an amount from your wages as a result of any grant or
     exercise of Options pursuant to this letter, the Company will not be
     required to deliver a stock certificate to you until you pay to the Company
     the amount required to be withheld from your wages with respect to such
     event. Payment of such amount may be in cash, withholding from other
     compensation or in shares of Common Stock with a Fair Market Value equal to
     such payment. Common Stock used to pay the withholding amount may be shares
     that you already own, or shares of Common Stock that you would otherwise
     have received upon the exercise of the Option.

          If you are subject to Section 16 of the Exchange Act, you shall have
     the unfettered right but not the obligation to direct and compel the
     Company to withhold, or to accept from you, such number of shares of Common
     Stock as is necessary to pay in whole or in part your withholding tax
     obligation, in accordance with Section 16(a)(i) of the Plan.

          (c)  No Restriction on Right of Company to Effect Corporate Changes.
     Neither the Plan nor this letter will affect or restrict in any way the
     right or power of the Company or its shareholders to make or authorize any
     corporate changes described in Section 13 of the Plan.

     4.   Notices. All notices and other communications discussed in this letter
will be in writing and will be delivered by hand or sent by mail addressed, if
to you, to your attention at the mailing address that you will have specified to
the Company in writing and, if to the Company, to it at 501 Pearl Drive, St.
Peters, Missouri 63376, Attention: Chief Financial Officer. All such notices
will be conclusively deemed to be received and will be effective, if sent by
hand delivery, upon receipt, or if sent by registered or certified mail, on the
fifth day after the day on which such notice is mailed.

     5.   Entire Letter; Governing Law. This letter and the Plan represent the
entire understanding between you and the Company and supersede all prior
understandings relating to the subject matter of this letter. This letter will
be governed by, and construed in accordance with, the laws of the State of
Delaware without giving effect to conflicts of law principles.
