                      PROXY STATEMENT -- VOTING PROCEDURES

YOUR VOTE IS VERY IMPORTANT


     MEMC is soliciting proxies to be used at our 2002 Annual Shareholders'
Meeting. This proxy statement and the proxy card will be mailed to shareholders
beginning May 20, 2002.


WHO CAN VOTE


     Record holders of MEMC common stock on April 26, 2002 may vote at the
annual meeting. On April 26, 2002, there were 70,238,660 shares of common stock
outstanding. The shares of common stock held in our treasury will not be voted.
Each share of common stock is entitled to one vote on each matter submitted to a
vote at the annual meeting.


HOW YOU CAN VOTE

     - BY PROXY -- Simply mark your proxy card, date and sign it, and return it
       in the envelope provided.

     - IN PERSON -- You can come to the annual meeting and cast your vote there.
       If your shares are held in the name of your broker, bank or other nominee
       and you wish to vote at the annual meeting, you must obtain a legal proxy
       or power of attorney from the nominee and present it at the meeting to
       establish your right to vote the shares.

HOW YOU MAY REVOKE OR CHANGE YOUR VOTE

     If you give a proxy, you may revoke it at any time before your shares are
voted. You may revoke your proxy in one of three ways:

     - Send in another proxy with a later date;

     - Notify our Corporate Secretary in writing before the annual meeting that
       you have revoked your proxy; or

     - Vote in person at the annual meeting.

SPECIAL VOTING RULES FOR PARTICIPANTS IN MEMC RETIREMENT SAVINGS PLAN

     The MEMC Stock Fund holds MEMC common stock as an investment alternative
for participants in the MEMC Retirement Savings Plan. Plan participants may
direct the plan's trustee how to vote the shares held by the plan, but only if
the participant signs and returns a voting direction card. If cards representing
shares held in the plan are not returned, the trustee will vote those shares in
the same proportion as the shares for which signed cards are returned by other
participants.

QUORUM

     A majority of the outstanding shares entitled to vote at the annual meeting
represented in person or by proxy will constitute a quorum. Abstentions and
broker non-votes are counted as present for establishing a quorum. A broker
non-vote occurs when a broker returns a proxy card but does not vote on one or
more matters because the broker does not have authority to do so. Shares
represented by proxies that are marked "withhold" with respect to the election
of one or more directors will be counted as present in determining whether there
is a quorum.

VOTE REQUIRED

     If a quorum is present at our annual meeting, the following vote is
required for approval of each matter to be voted on:

                                        1


ELECTION OF DIRECTORS            A plurality of the shares entitled to vote and
                                 present in person or by proxy at the meeting
                                 must be voted "FOR" each nominee. "Plurality"
                                 means that the nominees who receive the largest
                                 number of votes cast are elected as directors
                                 up to the maximum number of directors to be
                                 elected at the annual meeting. Consequently,
                                 any shares represented by proxies that are
                                 marked "withhold" will have no impact on the
                                 election of directors.

APPROVAL OF 2001 EQUITY
INCENTIVE PLAN                   A majority of the shares entitled to vote and
                                 present in person or by proxy at the meeting
                                 must be voted "FOR" this matter. Shares
                                 represented by proxies that are marked
                                 "abstain" with respect to this matter will be
                                 treated as shares present and entitled to vote.
                                 This will have the same effect as a vote
                                 against such matter. If a broker indicates on
                                 the proxy that it lacks discretionary authority
                                 as to certain shares to vote on this matter,
                                 the shares will not be considered as present
                                 and entitled to vote with respect to this
                                 matter.

COSTS OF SOLICITATION

     We will pay for preparing, printing and mailing this proxy statement.
Proxies may be solicited personally or by telephone by our regular employees
without additional compensation. We will reimburse banks, brokers and other
custodians, nominees and fiduciaries for their costs of sending the proxy
materials to our beneficial owners.

SELECTION OF AUDITORS

     We have appointed KPMG LLP as our independent accountant for the current
year ending December 31, 2002. KPMG LLP was our independent accountant for the
year ended December 31, 2001. A representative of KPMG LLP will be present at
the 2002 Annual Shareholders' Meeting, will have an opportunity to make a
statement, if desired, and will be available to respond to appropriate
questions.

                      ITEM NO. 1 -- ELECTION OF DIRECTORS

     The Board of Directors consists of ten members organized into three
classes, with each director elected to serve for a three-year term. There are
three directors in Class I (term expiring in 2002), three directors in Class II
(term expiring in 2003) and four directors in Class III (term expiring in 2004).

     Three directors will be elected at our 2002 annual meeting to serve for a
three-year term expiring at our annual meeting in the year 2005. The
Compensation and Nominating Committee has nominated Richard Boyce, John Danhakl
and Nabeel Gareeb for election as Class I (term expiring in 2005) directors at
this meeting. Each nominee is currently serving as a director having been
appointed by the Board to fill vacancies on the Board. Each nominee has
consented to serve for a new term. Each nominee elected as a director will
continue in office until his successor has been elected and qualified. If any
nominee is unable to serve as a director at the time of the annual meeting, the
persons named on the enclosed proxy card may vote for any alternative designated
by the present Board.

     You may not vote for more than three nominees. The persons named on the
enclosed proxy card intend to vote the proxy representing your shares for the
election of the three nominees named above, unless you indicate on the proxy
card that the vote should be withheld or you indicate contrary directions. If
you sign and return the proxy card without giving any direction, the persons
named on the enclosed proxy card will vote the proxy representing your shares
FOR the election of the three nominees named on the proxy card.

                 THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR"
                  THE ELECTION OF THESE NOMINEES AS DIRECTORS.

     The Audit Committee of the MEMC Board of Directors is currently composed of
three independent directors and operates under a written charter adopted by the
Board of Directors.

     We have met and held discussions with MEMC management and with MEMC's
independent accountants, KPMG LLP. We have reviewed and discussed the
consolidated financial statements of MEMC for 2001 with MEMC management. We
discussed with KPMG matters required to be discussed by generally accepted
auditing standards, including standards set forth in Statement on Auditing
Standards No. 61.

     KPMG also provided to us the written disclosures regarding their
independence required by Independence Standards Board Standard No. 1, and we
discussed with KPMG their independence.

     Based on these reviews and discussions, we recommended to the Board of
Directors that the audited consolidated financial statements for 2001 be
included in MEMC's Annual Report on Form 10-K for the year ended December 31,
2001 filed with the Securities and Exchange Commission.

(1) Audit related fees consisted principally of review of SEC registration
    statements and other filings and issuance of consents, statutory audits and
    audits of financial statements of certain employee benefit plans.

(2) Other non-audit fees consisted of tax compliance, employee benefit advice
    and tax business incentives.

     The Audit Committee has considered and determined that the provision of
non-audit services by KPMG LLP in 2001 is compatible with maintaining KPMG LLP's
independence.

                  COMPENSATION AND NOMINATING COMMITTEE REPORT

     Our executive compensation program is based on the premise that a balance
is required between our need to operate our business in an effective and
profitable manner and the competitiveness of rewards in competing for management
talent in the marketplace. The Compensation and Nominating Committee reviews
this program at least annually to ensure that this balance is maintained.

POLICIES, GOALS AND RESPONSIBILITIES

     The objective of the Compensation and Nominating Committee is to establish
compensation at a level that will allow us to attract, retain and motivate the
caliber of individuals required to manage and expand our business. We establish
compensation levels using guidelines developed by internationally recognized
compensation consultants. These guidelines are based upon survey data of
comparable U.S. companies, or comparable companies in the relevant geographic
area where an executive is located.

     Our 2001 guideline for executive compensation was based on the Towers
Perrin Executive Compensation Survey Database, General Industry, with a special
emphasis placed on a subset of the Towers Perrin Executive Compensation Survey
Database that included companies in the electronics and electrical equipment
industries. We consider the companies included in these surveys to be
representative of those with which we compete for executive officers and
employees. To retain and attract key executives, for 2001 the Compensation and
Nominating Committee utilized a compensation guideline that targeted base
salaries and annual incentives for executive officers at the 50th percentile of
the surveys. For long-term equity incentives, The Compensation and Nominating
Committee did not rely on the survey levels but determined award levels for
executive officers based on individual roles, responsibilities and performance.

     Our 2001 executive compensation program consisted of three components: (1)
base salary, (2) annual cash incentive awards, and (3) long-term equity
incentive awards.

BASE SALARIES

     We review the base salary of each executive officer on an annual basis. In
making base salary decisions, the Compensation and Nominating Committee first
reviews the comparable salary ranges from the compensation surveys. In addition,
we consider certain other factors and use discretion as appropriate when setting
base salary levels. For 2001, we continued to use an overall compensation
guideline that targeted base salaries for

                                        13


executive officers at the 50th percentile of companies included in the
compensation surveys. In setting base salaries for 2001, the Compensation and
Nominating Committee also considered the improved performance of the Company in
2000, the competitive position of each executive officer's base salary in the
market, personal performance and level of contribution.

     For 2001, Mr. von Horde, the Company's CEO, received an increase in base
salary of $45,000. Mr. von Horde's 2001 base salary was $565,000. In increasing
Mr. von Horde's base salary, the Compensation and Nominating Committee
considered the compensation ranges from the compensation surveys, the fact that
Mr. von Horde received no increase in base salary in 2000, and the improved
performance of the Company in 2000.

     As a result of the difficult financial and market conditions experienced by
the Company in 2001, in December 2001 the Compensation and Nominating Committee
approved a twenty percent (20%) reduction in each executive officer's base
salary effective as of January 1, 2002. This base salary reduction is effective
until such time as the Company attains certain financial objectives as may be
established by the Compensation and Nominating Committee or the Board of
Directors.

ANNUAL CASH INCENTIVE AWARDS

     Participation in our Annual Incentive Bonus Plan is discretionary and the
plan is non-contractual. Under current practice, we make annual cash awards to
certain management, professional and technical personnel to recognize and reward
individual and corporate performance.

     The Compensation and Nominating Committee establishes a performance/payout
schedule each year to set target bonuses (as a percentage of base salary) for
each designated participant. For 2001, we continued the use of the overall
compensation guideline that targeted annual incentives for executive officers at
the 50th percentile of companies included in the compensation surveys. In
setting target bonuses for 2001, we also considered personal performance and
level of contribution and the need to retain and attract key executive officers
as the Company continued to recover from the difficult market and financial
conditions experienced in the last several years. The Compensation and
Nominating Committee generally did not adjust the target annual bonus levels for
executive officers as compared with 1999, except in cases of substantial changes
in responsibility. The 2001 target bonus levels for participants ranged from 8%
to 140% of each participant's annual base salary.

     The 2001 annual incentive award for executive officers was subject to three
factors: (1) the Company's performance against a certain financial target, (2)
the participant's performance against his or her individual goals and (3) a
discretionary award as determined by management. A certain percentage of a
participant's target bonus was dependent on each of these factors, and each
factor was independent of the other factors.

     In 2001, if the financial target was met, then each participant who was an
executive officer received fifty percent (50%) of his or her target bonus. Each
such participant could receive up to twenty-five percent (25%) of his or her
target bonus based on his or her performance against individual goals. The
remaining twenty-five percent (25%) of each such participant's target bonus was
discretionary.

     The 2001 annual incentive plan also included a provision providing for the
immediate payment of a bonus if events occurred which resulted in a change in
control, as defined in the Company's 1995 Equity Incentive Plan. These events
occurred in November 2001 as a result of the closing of the transaction between
E.ON AG and an investor group led by Texas Pacific Group. However, in advance of
the closing, the Special Committee of the Board of Directors terminated the 2001
annual incentive plan and authorized management to design and implement another
plan which did not contain the change in control provision.

     Under the new 2001 annual incentive plan, all participants who were
employed on March 15, 2002, except Mr. von Horde and certain executive officers
and employees who either entered into separation agreements or new employment
agreements with the Company, received an award equal to 100% of the
participant's target bonus. The award was paid in the form of cash and
restricted stock. The restricted stock award will vest 50% on March 15, 2002 and
50% on March 15, 2003.

                                        14


     In consideration of the payments to be made to Mr. von Horde under his
retirement agreement, Mr. von Horde did not receive an annual incentive bonus
for 2001.

LONG-TERM INCENTIVE AWARDS

     Our long-term incentive bonus plan provides for equity-based compensation
in the form of annual grants of non-qualified stock options with twenty-five
percent (25%) of such options vesting on each anniversary of the date of grant.
The non-qualified stock options have an exercise price equal to 100% of the
market value of the Company's stock on the date of grant.

     In 2001, the Compensation and Nominating Committee used discretion in
determining stock option award levels for executive officers taking into
consideration individual roles and responsibilities, along with personal
performance and level of contribution.

     Mr. von Horde's employment agreement provides for annual grants of stock
options to purchase a number of shares with a face value of 200% of his base
salary, not to exceed 100,000 shares in any one year. Consistent with this
employment agreement, in 2001 we awarded Mr. von Horde non-qualified stock
options to purchase 100,000 shares of stock.

PENSION PLAN

     MEMC sponsors the MEMC Pension Plan, a defined benefit pension plan which
covered most U.S. employees of MEMC and its subsidiaries during the year. At the
end of 2001, the plan was amended to freeze the accrued benefit for employees
who did not meet certain age and service criteria. In order to receive future
benefit accruals, a participant must have met one of two criteria: 1) as of
December 31, 2001, the participant was at least age 50 with 5 years of service;
or, 2) the participant had at least 25 years of service as of December 31, 2001.
No future employees will be eligible for coverage under this plan.

     The basic benefit payable under the MEMC Pension Plan is determined based
on a lump sum equal to 8% of a participant's "average total earnings" (as
defined below) up to one-half of the Social Security wage base plus 12% of the
participant's average total earnings over one-half of the Social Security wage
base, multiplied by the participant's years of benefit service, less 2% of such
amount for every year by which the current age of the participant is less than
age 65 (the "Basic Formula"). In addition to the normal annuity options, a
portion of the benefit is also available in an immediate lump-sum distribution
at termination of employment.

     Employees who were participants in our former Pension Plan for Salaried
Employees (the "Salaried Plan"), a prior plan merged into the MEMC Pension Plan
as of December 31, 1996, are entitled to a benefit calculated under the formula
in effect as of such date under the Salaried Plan, if such benefit is greater
than the benefit calculated under the Basic Formula. The basic benefit payable
under the Salaried Plan formula is a

                                        17


single life annuity equal to 1.2% of the participant's average total earnings
multiplied by the participant's years of benefit service. However, if the
participant was hired in the United States by Monsanto Company ("Monsanto"), a
prior owner of a substantial part of our business, before April 1, 1986 and was
employed by us at any time during the period April 1, 1989 through May 31, 1989,
or if the participant was employed by MEMC at any time during the period January
1, 1989 through March 31, 1989, the factor is 1.4% of the participant's "average
total earnings" instead of 1.2%. If a participant with either the 1.2% or 1.4%
formula retires on or after age 55 but prior to age 65, his benefit will be
reduced 1/4% for each month that his retirement date precedes his 65th birthday.
However, if the participant is under age 65 but at least age 55 at the time of
his retirement, and the participant's age and years of vesting service add up to
at least 80, then the benefit is not subject to any reduction.

     The basic benefit under either the 1.2% or 1.4% formula is reduced by the
amount the participant is entitled to receive under any other designated
Monsanto defined benefit pension plan.

     For purposes of the MEMC Pension Plan, "average total earnings" means
twelve times the greater of (a) the monthly average earnings received in the 36
full calendar months immediately prior to the date of employment termination or
(b) the monthly average of earnings received during the highest three of the ten
calendar years immediately prior to the year in which employment terminates.
"Earnings" means amounts paid to participants that are subject to federal income
tax withholding (including salary and bonus payments), subject to certain
adjustments. Generally, "earnings" utilized for pension formula purposes
includes salary and annual bonus reported in the salary and bonus columns of the
Summary Compensation Table. However, earnings utilized for pension formula
purposes does not include payments in lieu of accrued vacation, sign-on bonuses
and the special incentive bonuses paid in 1999. In addition, since annual
incentive bonuses are paid in the year following the year earned, such bonuses
are included in earnings utilized for pension formula purposes in the year
following the year such bonuses are reported in the bonus column of the Summary
Compensation Table.

     Retirement benefits payable under qualified defined benefit plans are
subject to the annual pension limitations imposed under Section 415 of the
Internal Revenue Code, for which limitations vary annually. The Section 415
limitation for 2001 is $140,000. In addition, Section 401(a)(17) of the Internal
Revenue Code specifies a maximum amount of annual compensation, also adjusted
annually, that may be taken into account in computing benefits under a qualified
defined benefit plan. The Section 401(a)(17) limitation for 2001 is $170,000.
However, for 2002 the Section 401(a)(17) limitation was increased to $200,000
which increased amount could be applied retroactively to all prior years.
Effective in January 2002, we amended the MEMC Pension Plan to apply this
$200,000 limitation to all prior years. Our Supplemental Executive Pension Plan
(the "MEMC SEPP"), a non-qualified and unfunded plan, provided benefits over the
applicable Internal Revenue Code limitations. Benefits under the MEMC SEPP are
payable in the form of a lump-sum distribution, in the form of an annuity with
monthly payments for life beginning at the participant's retirement age, or in
annual installments not to exceed fifteen years. The MEMC SEPP was amended at
the end of the year to cease future accruals. In addition, all accrued benefits
under the MEMC SEPP for employees who entered into new employment contracts with
the Company were waived.

     The following table shows the estimated annual pension benefits under the
MEMC Pension Plan and the MEMC SEPP in the remuneration and years of service
classifications indicated using the Basic Formula. The table is based on the
2001 Social Security Wage Base, a 6.0% interest rate and the GAM83(50/50)
Mortality Table. In addition, the amounts in the table assume that a participant
met the criteria for continued benefit

                                        18


accrual effective as of December 31, 2001. The amounts shown in the table are
calculated on a single life annuity basis and assume retirement at age 65.

</Table>

     Mr. von Horde and Mr. Glaser are covered by the Basic Formula. As of
December 31, 2001, Mr. von Horde had 3.8 years of benefit service and annualized
average total earnings of $903,174. Under the terms of the MEMC Pension Plan and
MEMC SEPP, because Mr. von Horde did not participate in the MEMC Pension Plan
and MEMC SEPP until April 1, 1998, as of December 31, 2001, Mr. von Horde had no
vested benefit. As of December 31, 2001, Mr. Glaser had 2.8 years of benefit
service and annualized average total earnings of $268,690. Under the terms of
the MEMC Pension Plan and MEMC SEPP, because Mr. Glaser joined MEMC in March
1999, as of December 31, 2001, Mr. Glaser had no vested benefit. Neither Mr. von
Horde nor Mr. Glaser met the criteria for continued benefit accrual effective
December 31, 2001.

     In connection with certain reduction in force actions occurring in 2001 and
2002, we amended the MEMC Pension Plan to provide that participants terminated
as part of a reduction in force prior to June 30, 2002 would be fully vested in
their accrued benefit. Because Mr. Glaser terminated his employment as part of a
reduction in force action, upon his termination on February 28, 2002 his $36,544
accrued lump-sum benefit under the MEMC Pension Plan became fully vested.

     Under the terms of his retirement agreement, Mr. von Horde will be entitled
to a lump sum payment of $374,901 in full settlement of his accrued benefit
under the MEMC Pension Plan and MEMC SEPP. See "Retirement Agreement -- Klaus R.
von Horde."

     The following table shows the estimated annual pension benefits under the
MEMC Pension Plan and the MEMC SEPP in the remuneration and years of service
classifications indicated using the 1.4% Salaried Plan formula described above.
As discussed above, the 1.4% formula is an alternative to the Basic Formula. The
amounts shown in the table assume that a participant met the criteria for
continued benefit accrual effective as

                                        19


of December 31, 2001. In addition, the amounts shown in the table are calculated
on a single life annuity basis and assume retirement at age 65 (without regard
to the offsets described above).

     Dr. DeLuca and Mr. Jansky are covered by the 1.4% formula. As of December
31, 2001, Dr. De Luca had 24.6 years of benefit service and annualized average
total earnings of $287,988, and Mr. Jansky had 28.0 years of benefit service and
annualized average total earnings of $304,925.

     Upon his retirement on January 31, 2002, Dr. DeLuca's annual single life
annuity benefit from the MEMC Pension Plan was $56,835 and his lump-sum benefit
under the MEMC SEPP was $393,001.

     The following table shows the estimated annual pension benefits under the
MEMC Pension Plan and the MEMC SEPP in the remuneration and years of service
classifications indicated using the 1.2% Salaried Plan formula described above.
As discussed above, the 1.2% formula is an alternative to the Basic Formula. The
table presents the better of the Basic Formula or the grandfathered 1.2% formula
for each level of remuneration and years of service classification as a single
life annuity assuming retirement at age 65. The basic benefit is calculated
using the 2001 Social Security Wage Base, a 6% interest rate and the
GAM83(50/50) Mortality Table to convert the lump sums to annuities. The amounts
shown in the table assume that a participant met the criteria for continued
benefit accrual effective as of December 31, 2001.

       employees

       determined by the Board with a target bonus of 50% of annual base salary

       value on the date of grant, of which 50% will vest ratably over four
       years and 50% will vest on the seventh anniversary of the date of grant
       or earlier if certain financial and operating objectives are achieved

  JULIUS R. GLASER

     Effective as of February 28, 2002, Mr. Glaser resigned from MEMC. In
connection with his resignation, Mr. Glaser entered into a separation agreement
with MEMC. The separation agreement provides for:

     - A lump-sum cash payment of $442,133

     - Vesting of all unvested options under MEMC's 1995 Equity Incentive Plan
       which options will be exercisable until February 28, 2005

     - Outplacement services not to exceed $18,000

                                        22


     The above payments and benefits are in lieu of any amounts payable to Mr.
Glaser under his prior employment agreement effective as of February 10, 1999,
the MEMC Severance Plan for Senior Officers and any other plan in which Mr.
Glaser was a participant other than his accrued benefits under certain
retirement plans. The separation agreement also included a release and waiver of
certain employment related claims.

RETIREMENT AGREEMENT

  KLAUS R. VON HORDE

     In connection with Mr. von Horde's retirement as our President and Chief
Executive Officer effective April 30, 2002, MEMC entered into a retirement
agreement with Mr. von Horde in April 2002. Pursuant to the retirement
agreement, Mr. von Horde will receive the following in lieu of all amounts to
which Mr. von Horde was entitled under all MEMC plans and his employment
agreements:

     - Installment payments totaling $565,000 (subject to tax withholding) over
       the next twelve months, provided that any time on or after September 1,
       2002, Mr. von Horde may elect to terminate the installment payments and
       receive the balance in a lump-sum cash payment

     - Lump-sum cash payment of $342,500 (subject to tax withholding) upon
       payment in full of the above installment payments

     - Lump-sum cash payment of $374,901 upon payment in full of the above
       installment payments in full settlement of accrued pension obligations
       owed by MEMC

     - Fully vested, three-year options to purchase 100,000 shares of MEMC
       common stock at an exercise price of $3.55 per share and 20,000 shares of
       MEMC common stock at an exercise price of $1.50 per share

     - Grant of 198,744 shares of MEMC common stock to be subject to a
       restricted stock agreement with certain vesting conditions

     - Participation in MEMC's medical and dental plans for the duration of the
       above installment payments on the same terms as similarly situated
       employees


     With respect to stock options awarded to Mr. von Horde prior to retirement,
those that were not vested as of April 30 were cancelled, and those that were
vested as of April 30 became exercisable for 60 days. The retirement agreement
also includes mutual releases of certain claims.


SEVERANCE PLAN FOR SENIOR OFFICERS

     On October 15, 1999, we adopted a severance plan for our senior officers.
The plan provided severance benefits to certain key executive officers in the
event of their termination of employment both before and after a change of
control of MEMC. Executive Vice Presidents and Corporate Vice Presidents
reporting to MEMC's Chief Executive Officer were eligible to participate in the
plan. However, the Compensation and Nominating Committee must designate all
participants. All of the participants in this plan have either terminated their
employment with MEMC or waived their rights under the plan in connection with
the execution of separation agreements or new employment agreements.
Accordingly, there are currently no participants in the plan.

     The plan has the initial term of three years ending October 15, 2002. After
the initial term, the plan automatically renews for successive one-year terms
until terminated on twelve months' prior notice to each participant. However, if
there is a change in control of MEMC, the plan continues for two years following
the change in control at which time the plan will terminate. The transaction
between the investor group led by Texas Pacific Group and E.ON AG and its
affiliates that closed on November 13, 2001 constituted a change of control
under the plan. Accordingly, the plan will terminate on November 13, 2003.

     The Compensation and Nominating Committee may remove a participant from the
plan by giving the participant twelve months' notice. However, no participant
may be removed from the plan for two years following a change in control of
MEMC.

                                        23


     A participant is entitled to severance benefits under the plan in the event
that he or she is:

     - Involuntarily terminated, other than for cause, while a participant in
       the plan; or

     - Constructively discharged within two years following a change in control
       of MEMC.

     A participant is not entitled to severance benefits under the plan in the
event of his or her termination of employment on account of death, total and
permanent disability, voluntary termination of employment by the participant or
termination of employment by MEMC for cause.

     Participants who are entitled to severance benefits under the plan receive
the following:

CASH COMPENSATION

     Salary:  The greater of (1) one year's base salary in effect at the time of
termination of employment without any accrued and unused vacation or (2) two
weeks of such salary for each year of service with MEMC plus one additional
week's salary plus accrued and unused vacation.

     Bonus:  A pro rata bonus for the year of termination based on the number of
days in the year before the termination date. The bonus will be determined based
on the actual level of achievement of the relevant goals. However, if the
termination of employment occurs within two years following a change in control,
then (1) the pro rata bonus will be based on the full targeted level and (2) the
participant will receive an additional payment equal to the bonus the
participant would have received for the year of termination at the full targeted
level.

STOCK OPTIONS

     If the termination of employment occurs within two years following a change
in control, then the participant will be deemed to have retired for purposes of
determining the vesting and expiration of all stock options previously granted
to the participant.

RETIREMENT BENEFITS

     For purposes of determining benefits payable under the MEMC SEPP, the
period used above to determine the salary severance benefit (e.g., either one
year, or two weeks for each year of service plus one additional week) will be
treated as additional service to MEMC.

MEDICAL AND DENTAL BENEFITS

     A participant will receive a payment equal to the cost of 18 months of
COBRA premiums for dental coverage for the same level of coverage the
participant is enrolled immediately prior to his or her termination. In
addition, if a participant is not eligible for retiree medical benefits, the
participant will receive an additional payment equal to the cost of 18 months of
COBRA premiums for medical coverage for the same level of coverage the
participant is enrolled immediately prior to his or her termination. These
payments will be grossed up for taxes.

CHANGE IN CONTROL

     The Company's stock option plans and certain award agreements under such
plans provide for acceleration of vesting in the event of a change in control of
MEMC and/or in the event of termination of employment by MEMC without cause or
by the participant for good reason within two years following a change in
control of MEMC, as defined in those plans. Our named executives participate in
these plans.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     From January to November 2001, the Compensation and Nominating Committee
was comprised of Dr. Hans Michael Gaul, Mr. Helmut Mamsch, Dr. Alfred Oberholz,
Mr. Paul T. O'Brien, Prof. Dr. Wilhelm

                                        24


Simson and Ambassador Michael B. Smith. Since December 2001, the Compensation
and Nominating Committee has been comprised of Mr. Robert J. Boehlke, Mr. John
Marren and Mr. C. Douglas Marsh.

     Drs. Gaul, Oberholz and Simson and Mr. O'Brien are executive officers
and/or directors of E.ON AG or one or more of its affiliates. Mr. Mamsch is a
former executive officer of VEBA AG, a predecessor company of E.ON AG. E.ON AG,
through certain of its subsidiaries, owned 71.8% of the outstanding shares of
MEMC common stock until November 13, 2001. Mr. Marren is a partner with Texas
Pacific Group. An investor group led by Texas Pacific Group currently owns 71.8%
of the outstanding shares of MEMC common stock, 100% of the outstanding shares
of MEMC Series A Cumulative Convertible Preferred Stock and 100% of the
16,666,667 outstanding warrants to purchase MEMC common stock. For a description
of certain transactions and arrangements between MEMC and E.ON AG and its
affiliates and between MEMC and the investor group led by Texas Pacific Group,
see "CERTAIN TRANSACTIONS," below.

     None of the directors comprising the Compensation and Nominating Committee
during 2001 has been an officer or employee of MEMC or any of its subsidiaries.
Because the full Board of Directors approved certain compensation
recommendations of the Compensation and Nominating Committee, Mr. von Horde is
deemed to have participated in deliberations of the Board of Directors regarding
remuneration paid to executive officers.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Based on our review of the Forms 3, 4 and 5 furnished to us, all of the
filings for our executive officers and directors and greater than 10%
shareholders required under Section 16(a) of the Securities Exchange Act of 1934
were made on a timely basis in 2001.

                              CERTAIN TRANSACTIONS

     E.ON North America, Inc., a corporation owned by E.ON AG and its
subsidiaries, and VEBA Zweite Verwaltungsgesellschaft mbH, another subsidiary of
E.ON AG, collectively owned approximately 72% of the outstanding shares of MEMC
common stock until November 13, 2001. On September 30, 2001, E.ON AG and its
affiliates (E.ON) entered into a purchase agreement with an investor group led
by Texas Pacific Group, including TPG Wafer Holdings LLC and funds managed by
Leonard Green & Partners, L.P. and TCW/Crescent Mezzanine Management III LLC
(collectively, TPG). Pursuant to the purchase agreement, on November 13, 2001,
TPG Wafer Holdings and its assignees purchased all of E.ON's debt in MEMC of
approximately $910 million and all of E.ON's equity holdings in MEMC,
representing approximately 72% of the outstanding shares of MEMC common stock.

     In an effort to minimize conflicts of interest by members of our Board of
Directors affiliated with E.ON, TPG or other related parties, the Audit
Committee, or a special committee consisting entirely of independent directors,
generally approves or ratifies any material transaction with a related party. A
special committee approved the transactions described under "TPG RESTRUCTURING
AGREEMENT," below.

     In 2001, we made payments to E.ON AG and certain of its affiliates for
software maintenance, raw materials, equipment and services, credit commitments
and interest. We also participated in E.ON AG's global treasury management
system. MEMC Pasadena, Inc., our granular polysilicon subsidiary, sold granular

                                        26


polysilicon to an affiliate of E.ON AG. Our significant agreements and
arrangements between E.ON AG and its affiliates are more fully described below.

     In connection with and as a condition to closing the transactions
contemplated by the purchase agreement between E.ON and TPG, on November 13,
2001, we entered into a restructuring agreement with TPG Wafer Holdings under
which we restructured approximately $860 million of our debt that was acquired
by TPG from E.ON. As part of the transactions contemplated by the purchase
agreement and restructuring agreement, we also entered into certain agreements
with TPG, E.ON and their respective affiliates as more fully described below.

AGREEMENTS AND TRANSACTIONS WITH E.ON

LOAN AGREEMENTS

     In 2001, MEMC incurred approximately $69.5 million in interest expense,
commitment fees and other financing fees to E.ON AG and certain of its
affiliates. We had entered into a number of credit and loan arrangements with
E.ON AG and its affiliates. These loan and credit agreements with E.ON AG and
its affiliates provided that the maturities on all outstanding debt maturing
prior to January 1, 2002 would be extended until their respective maturity date
anniversaries in 2002 (but only in the event we had used our best efforts to
obtain replacement financing on equivalent terms and conditions and had been
unsuccessful). On November 13, 2001, we had approximately $910 million of U.S.
dollar, Euro and Japanese yen based loans outstanding with E.ON AG and its
affiliates. These loans had interest rates ranging from 3.5% to 11.8% with
annual commitment fees of 1/4 of one percent on the undrawn portion of these
loans.

     On November 13, 2001, our loan and credit agreements with E.ON AG were
assigned by E.ON to TPG pursuant to the terms of the purchase agreement and
restructured as part of a restructuring agreement. See "CHANGE IN CONTROL" and
"TPG RESTRUCTURING AGREEMENT" below.

TREASURY MANAGEMENT

     Under an informal arrangement, MEMC participated in E.ON AG's global
treasury management system. As part of this arrangement, we generally offered
E.ON AG or an affiliate a right of first refusal to act as our financial
intermediary in transacting currency hedging activities. As a result of this
arrangement, we entered into a number of foreign exchange hedging contracts
using E.ON AG or an affiliate as our financial intermediary. MEMC believes that
these hedging arrangements with E.ON AG or an affiliate allowed for transactions
on terms that were comparable to terms available from unrelated third party
financial intermediaries.

     In anticipation of the closing of the transactions contemplated by the
purchase agreement between E.ON and TPG, on November 9, 2001 we terminated all
of our hedging arrangements with E.ON. In full settlement of these hedging
arrangements, E.ON paid MEMC approximately $4.3 million and approximately 3.8
billion Italian Lira. We believe the exchange rates and interest rates used to
determine the settlement amounts were comparable to rates that would have been
used by unrelated third party financial institutions to settle such hedging
agreements.

PURCHASES OF EQUIPMENT AND RAW MATERIALS

     We purchased equipment and related maintenance services from an affiliate
of Steag AG. E.ON AG holds a significant minority ownership interest in Steag
AG. We believe that the price we paid for the equipment and services was not
materially different from the price that we could have obtained from unrelated
third parties for comparable equipment and services. In 2001, we paid Steag AG
and its affiliates approximately $3.9 million for equipment and related
services.

     We purchased raw materials from Degussa-Huls, an affiliate of E.ON AG. We
believe the price we paid for the raw materials was not materially different
from the price we could have obtained from third parties for similar products.
In 2001, we paid Degussa-Huls approximately $1.3 million for raw materials.

                                        27


SALES OF GRANULAR POLYSILICON

     MEMC Pasadena, Inc., our granular polysilicon subsidiary, sold granular
polysilicon to an affiliate of Siemens Solar GmbH. An affiliate of E.ON, AG
holds a significant minority ownership interest in Siemens Solar GmbH. We
believe that the prices received by MEMC Pasadena, Inc. for these sales were
comparable to the prices received by MEMC Pasadena, Inc. from sales to third
parties. In 2001, MEMC Pasadena, Inc. sold approximately $9.6 million of
granular polysilicon to the affiliate of Siemens Solar GmbH.

SAP SOFTWARE

     We obtained the use of SAP R/3 software and related maintenance services
through E.ON AG, which has a license and maintenance contract with SAP AG. SAP
R/3 software is a comprehensive enterprise resource planning software package
designed to integrate our various business processes. In 1999, we paid E.ON AG a
one-time fee of approximately $368,000 for the use of the SAP R/3 software. In
2001, we paid expenses to E.ON AG of approximately $285,000 for annual
maintenance charges related to SAP maintenance services. Because of E.ON AG's
volume pricing, we believe that both the one-time fee and the annual maintenance
charges were more favorable than we would have been required to pay if we had
independently contracted with SAP for the license and maintenance services. In
December 2001, we terminated the agreement with E.ON under which we obtained the
use of SAP R/3 software and related maintenance services and replaced this
agreement with a direct license agreement between us and SAP America.

AGREEMENT FOR COMMUNICATION SERVICES

     MEMC had an arrangement with E.ON North America, Inc. covering certain of
our communication service needs. This arrangement allowed MEMC to participate
with E.ON North America, Inc. and several of its affiliates in a communication
service agreement between E.ON North America, Inc. and AT&T. The term of the
communication services agreement expired in 2001. In return for volume pricing
discounts, E.ON North America, Inc. provided AT&T with minimum revenue
commitments for each contract year during the term of the communication services
agreement. MEMC entered into a reimbursement agreement with E.ON North America,
Inc. which required us to reimburse E.ON North America, Inc. if our payments to
AT&T under the communication services agreement did not meet certain minimum
levels for each contract year. The Company was not obligated to make any
reimbursement payments to E.ON North America, Inc. under this agreement. The
reimbursement agreement expired simultaneously with the communication services
agreement.

CHANGE IN CONTROL

     On September 30, 2001, E.ON and TPG entered into a purchase agreement.
Prior to the closing contemplated by the purchase agreement, TPG Wafer Holdings
formed MEMC Holdings Corporation as a wholly owned subsidiary.

     On November 13, 2001, E.ON and TPG completed the transactions contemplated
by the purchase agreement. Pursuant to the purchase agreement, TPG Wafer
Holdings and its assignees, including MEMC Holdings Corporation, purchased all
of E.ON's debt in MEMC of approximately $910 million for an aggregate purchase
price of $4.00 and all of E.ON's equity holdings in MEMC of 49,959,970 shares of
MEMC common stock, representing approximately 72% of the outstanding shares of
MEMC common stock, for an aggregate purchase price of $2.00. MEMC Holdings
Corporation acquired approximately $411 million of the $910 million total debt.
Pursuant to the purchase agreement, the purchase price payable by TPG to E.ON
may be increased by a maximum of $150 million, depending upon our financial
performance in 2002.

     Also at the closing, E.ON made capital contributions to MEMC as required
under the purchase agreement in the aggregate amount of $37 million, of which $5
million was contributed to enable us to make a contribution to our defined
benefit plan. In connection with these transactions, we and certain of our
subsidiaries have executed releases of E.ON from certain actions, causes of
action, suits, debts and other damages. In particular, we have released E.ON
from its obligations under the loan agreements, security agreements, guaranties
and associated documents relating to the debt acquired from E.ON by TPG. We have

                                        28


also released E.ON and certain of its affiliates from damages arising out of or
in connection with any of them having been a shareholder, noteholder or director
or officer of MEMC or any of its affiliates, and in connection with agreements
in which E.ON has provided services or financing to or at the request of MEMC or
any of its affiliates, except with respect to certain specified agreements.

     The obligations of TPG and E.ON to complete the transactions contemplated
by the purchase agreement were subject to, among other things:

     - TPG reaching definitive agreement with respect to an exchange by TPG of
       the loans being acquired from E.ON for newly issued debt and equity
       securities of MEMC, and

     - MEMC entering into a new revolving credit facility with TPG (or a
       comparable lender) for up to $150 million.

     The conditions to closing were satisfied and E.ON and TPG consummated their
sale and purchase on November 13, 2001. As described below, the transactions
contemplated by the debt restructuring agreement between TPG Wafer Holdings and
MEMC were also completed on November 13, 2001, except for the restructuring of
the debt of our Italian subsidiary. See "-- TPG RESTRUCTURING AGREEMENT" below.
We are currently reviewing with TPG alternatives to the originally contemplated
Italian debt restructuring, which will take place, if at all, at such time as
the parties may agree.

     As a result of these transactions, TPG now beneficially owns approximately
72% of the outstanding MEMC common stock and has exchanged approximately $860
million of the debt acquired from E.ON for:

     - all of the shares of our newly issued Series A Cumulative Convertible
       Preferred Stock with an aggregate stated value of $260 million;

     - $50 million in principal amount of our newly issued senior subordinated
       secured notes; and

     - warrants to purchase 16,666,667 shares of our common stock.

     TPG has also retained a senior secured term note issued by our Italian
subsidiary in the principal amount of 55 million Euro (approximately $50
million).

     Effective November 13, 2001, all of the E.ON affiliated members resigned
from the MEMC Board of Directors. In addition, on that date two of the
independent members of the Board also resigned. The Board established by
resolution that the Board will consist of nine persons and, on November 13,
2001, appointed four nominees to serve on the Board as designated by TPG Wafer
Holdings in the restructuring agreement. The Board has subsequently established
by resolution that the Board will consist of ten persons and has appointed four
additional persons to the Board, two of whom are independent directors who are
now serving on the Audit Committee of the MEMC Board.

TPG RESTRUCTURING AGREEMENT

GENERAL

     In connection with and as a condition of closing of the transactions
contemplated by the purchase agreement between E.ON and TPG, on November 13,
2001, we executed a definitive restructuring agreement with TPG Wafer Holdings.
Pursuant to the restructuring agreement, TPG Wafer Holdings exchanged with MEMC
all of the shares of the Class A Common Stock of MEMC Holdings Corporation, the
subsidiary holding company that had acquired approximately $411 million of the
debt purchased from E.ON, for 260,000 shares of our Series A Cumulative
Convertible Preferred Stock, having an aggregate stated value of $260 million.
Each share of the Series A Cumulative Convertible Preferred Stock is convertible
into shares of MEMC common stock at a conversion price of $2.25 per share,
subject to certain limitations and antidilution adjustments.

                                        29


     The following steps were then taken pursuant to the restructuring
agreement:

     - TPG exchanged with MEMC approximately $449 million of our debt acquired
       from E.ON for $50 million in principal amount of our senior subordinated
       secured notes, with warrants to acquire up to 16,666,667 shares of our
       common stock, subject to certain antidilution adjustments.

     - TPG retained an existing 55 million Euro (approximately $50 million) note
       from our Italian subsidiary.

     - TPG established a five-year revolving credit facility to make available
       to us up to $150 million in senior secured loans.

     - We entered into various agreements contemplated by the restructuring
       agreement, including a registration rights agreement and an agreement and
       plan of merger relating to the merger agreement between MEMC and TPG
       Wafer Holdings.

     TPG Wafer Holdings subsequently exchanged with MEMC the one outstanding
share of Class B Common Stock of MEMC Holdings Corporation for a promissory note
having a principal amount of $250. As a result, MEMC Holdings Corporation is now
a wholly owned subsidiary of MEMC.

SHAREHOLDER APPROVAL


     Pursuant to the restructuring agreement, we agreed to use our best efforts
to obtain, as promptly as possible, (i) any necessary approval by our
shareholders relating to the Series A Cumulative Convertible Preferred Stock,
the shares issuable upon conversion of the Series A Cumulative Convertible
Preferred Stock, the warrants and the shares issuable upon exercise of the
warrants under the rules and regulations of the New York Stock Exchange, (ii)
the approval by our shareholders of the plan of merger between MEMC and TPG
Wafer Holdings contained in the merger agreement in accordance with the Delaware
General Corporation Law, and (iii) the approval by our shareholders of a
one-for-two reverse split of our common stock. We have filed a preliminary proxy
statement with the Securities and Exchange Commission in connection with a
special shareholders' meeting for the purpose of approving the above items along
with an increase in our authorized capital stock from 200,000,000 shares of
common stock to at least 250,000,000 shares of common stock. The timing of the
special shareholders' meeting is dependent upon the timing of the completion of
the review of the preliminary proxy statement by the Securities and Exchange
Commission.


OWNERSHIP OF MEMC AFTER RESTRUCTURING TRANSACTIONS

     If the preferred stock and warrants are approved by our shareholders, TPG
will own or have the right to acquire, through ownership of the common stock
acquired from E.ON, conversion of the preferred stock (excluding accrued but
unpaid dividends) and exercise of the warrants, a minimum of approximately 182
million shares of our common stock, which would represent approximately 90% of
our outstanding common stock. Because the preferred stock earns cumulative
dividends that may be payable in kind upon conversion, if TPG were not to
convert any preferred stock until immediately prior to the earliest redemption
date, TPG would own or have the right to acquire a maximum of approximately 364
million shares of our common stock, which would represent approximately 95% of
our outstanding common stock.

BOARD REPRESENTATION

     The restructuring agreement required the MEMC Board of Directors to appoint
a total of four nominees designated by TPG Wafer Holdings prior to the closing,
to be allocated to the different director classes as specified by TPG Wafer
Holdings. In addition, the restructuring agreement provides that commencing with
the next annual meeting of our shareholders, and at each annual meeting
thereafter, TPG Wafer Holdings shall be entitled to present to the Board of
Directors a number of nominees for election to the class of directors up for
election at such annual meeting equal to the number of TPG Wafer Holdings
nominees in such class immediately prior to such election. We have agreed to
cause each such TPG Wafer Holdings designated nominee to be included in the
slate of nominees recommended by the Board to the shareholders for election, and
to use our best efforts to cause those nominees to be elected. TPG Wafer
Holdings will have these

                                        30


contractual rights so long as at least $130 million in stated value of the
Series A Cumulative Convertible Preferred Stock remains outstanding and TPG
Wafer Holdings and its affiliates beneficially own greater than 50% of the
preferred stock. As a practical matter, TPG Wafer Holdings currently possesses
the power to elect all of our directors through its beneficial ownership of a
majority of our voting stock.

NOTES AND WARRANTS

     The senior subordinated secured notes due 2007 issued by MEMC under the
terms of the restructuring agreement are guaranteed by our domestic subsidiaries
and bear interest at a rate of 8% (payment in kind) in the first two years
following issuance, 14% (payment in kind) in the third and fourth years
following issuance and 14% (payment in kind with optional payment in cash at the
request of the note holders) in the fifth and sixth years following issuance. As
collateral under the notes, we have pledged substantially all of our domestic
assets, including all of the capital stock of most of our domestic subsidiaries
and 65% of the capital stock of certain of our foreign subsidiaries, but
excluding any assets currently pledged to support third party debt. The notes
and the related security interest are subordinate in priority and in right of
payment to the Citibank revolving credit agreement and the reimbursement
agreement, which are described under "-- Credit Agreement" below. In addition,
the notes and related indenture contain substantially the same loan covenants as
the Citibank revolving credit agreement, which are described under "-- Credit
Agreement" below.

     The warrants issued by MEMC entitle the holders to purchase an aggregate of
16,666,667 shares of MEMC common stock at an exercise price of $3.00 per share,
subject to certain antidilution adjustments. The warrants may only be exercised
after shareholder approval of the warrants. See "Shareholder Approval" above.
Assuming shareholder approval is obtained, the warrants may be exercised, in
whole or in part, at any time and from time to time until their expiration on
November 13, 2011.

     Pursuant to the restructuring agreement, we have agreed to restructure the
55 million Euro (approximately $50 million) debt issued by our Italian
subsidiary, on terms set forth in the restructuring agreement. It was originally
contemplated that our Italian subsidiary would secure and deliver to TPG a
senior secured note due 2031 in the principal amount of 55 million Euro,
guaranteed by MEMC, bearing interest at a rate of 6% per annum (payment in kind)
and secured by assets of the Italian subsidiary. The parties have been unable to
restructure the Italian debt on the original terms contemplated in the
restructuring agreement. We are currently reviewing with TPG alternatives to the
originally contemplated restructuring of this debt, which will take place, if at
all, at such time as the parties may agree.

REGISTRATION RIGHTS AGREEMENT

     We have entered into a registration rights agreement with TPG providing for
registration rights with respect to the preferred stock, the shares of common
stock issuable upon conversion of the preferred stock, the warrants, the shares
of common stock issuable upon exercise of the warrants, the notes and the
accompanying guarantees and any shares of common stock owned or acquired by TPG
(including the shares acquired by TPG from E.ON pursuant to their purchase
agreement). We have agreed that, on or before August 10, 2002, we will file with
the Securities and Exchange Commission a shelf registration statement on Form
S-3 covering resales of these registrable securities by the holders of the
registrable securities.

CREDIT AGREEMENT

     In connection with the restructuring, TPG originally established a
five-year revolving credit facility pursuant to which the TPG lender parties
committed to make available to us a line of credit in an aggregate amount of
$150 million. Pursuant to this credit agreement, loans would be made subject to
the following aggregate lending limitations:

     - $50 million at any time prior to January 1, 2002,

     - $75 million at any time prior to April 1, 2002,

     - $100 million at any time prior to July 1, 2002,

                                        31


     - $125 million at any time prior to October 1, 2002, and

     - $150 million at any time on and after October 1, 2002.

     The TPG credit facility provided that loans would bear interest at a rate
of LIBOR plus 3.5% per annum or an alternate base rate (based upon the greater
of the Federal funds rate plus 0.5% and Citibank N.A.'s prime rate) plus 2.5%
per annum. As collateral under this credit agreement, we pledged substantially
all of our domestic assets, including all of the capital stock of most of our
domestic subsidiaries and 65% of the capital stock of certain of our foreign
subsidiaries, but excluding any assets then currently pledged to support third
party debt. Our domestic subsidiaries also guaranteed our payment obligations
under the credit agreement.

     Subsequent to the original closing of the debt restructuring transactions,
we made arrangements to replace the TPG revolving credit facility with a
substantially similar five-year revolving credit facility with an affiliate of
Citibank, N.A. On December 21, 2001, we entered into the new Citibank credit
facility which replaced the TPG credit facility. In April 2002, Citibank
assigned 50% of its interest in this credit facility to UBS AG. The interest
rate under the Citibank facility is LIBOR plus 1.5% or an alternative base rate
(based upon the greater of the Federal funds rate plus 0.5% and Citibank's prime
rate) plus 0.5% per annum. TPG has guaranteed our obligations under the new
Citibank facility, and in return, we have entered into a reimbursement agreement
with the guarantors under which we have agreed to reimburse them for any
payments made under the guaranty. Both the Citibank credit facility and the
reimbursement agreement are secured by substantially the same collateral that
secured the original TPG credit facility. As with the TPG facility, our domestic
subsidiaries have guaranteed MEMC's obligations under the Citibank facility and
the reimbursement agreement. The subsidiary guaranties are supported by security
interests in substantially all of the assets of the domestic subsidiaries. The
Citibank credit facility contains certain loan covenants, including covenants to
maintain minimum quarterly consolidated earnings before interest, taxes,
depreciation and amortization; minimum monthly consolidated backlog; minimum
monthly consolidated revenues; maximum annual capital expenditures; and other
covenants customary for revolving loans of this type and size. MEMC must
maintain compliance with these covenants in order to draw on the facility. In
addition, outstanding loans under the credit facility will become due and
payable if we are in breach of the loan covenants and such breach causes an
event of default under the credit facility.

MERGER AGREEMENT

     Pursuant to an agreement and plan of merger, we have agreed to permit the
merger of TPG Wafer Holdings with and into us at such time as TPG Wafer Holdings
shall determine. We will continue in existence as the surviving corporation. In
connection with the merger, the members of TPG Wafer Holdings will convert their
limited liability company interests in TPG Wafer Holdings into equivalent equity
securities of us held by TPG Wafer Holdings, plus common stock having a market
value equal to the principal amount of the debt securities of MEMC held by TPG
Wafer Holdings and the accrued but unpaid interest on such debt securities. TPG
Wafer Holdings currently does not directly hold any debt of MEMC and has
indicated it has no current intention to acquire debt of MEMC. The merger is
subject to the approval of our shareholders and the members of TPG Wafer
Holdings. The agreement and plan of merger is being submitted to our
shareholders for approval at the special shareholders meeting described above.
See "-- Shareholder Approval" above.

MANAGEMENT ADVISORY AGREEMENT

     In connection with the restructuring, we have entered into a management
advisory agreement with TPG GenPar III, L.P., an affiliate of Texas Pacific
Group. Pursuant to the agreement, TPG GenPar III will provide management and
financial advisory services to us as requested by our Board of Directors in
exchange for a management advisory fee of $2 million per annum plus additional
compensation if TPG GenPar III acts as a financial advisor to us for future
transactions such as a merger or debt or equity financing.

                                        32


TAX CONSISTENCY AGREEMENT

     In 2001, following the closing of the transactions contemplated by the
purchase agreement and restructuring agreement, we entered into a tax
consistency agreement with MEMC Holdings Corporation, TPG Wafer Partners LLC and
TPG Wafer Holdings. This agreement sets forth the income tax elections to be
made and the anticipated U.S. federal income tax treatment of the transactions
contemplated by the purchase agreement and the restructuring agreement.

FEES AND EXPENSES

     We are responsible for the payment of all our expenses incurred in
connection with the restructuring agreement and the subsequent negotiation and
documentation of the Citibank replacement credit facility, including all fees
and expenses of our legal counsel and all third-party consultants engaged by us
to assist in such transactions. We have paid TPG a $10 million transaction fee
in connection with the restructuring agreement. In addition, we expect to pay
TPG, Citibank and UBS a total of $3 million in fees (of which TPG will receive
up to approximately $1.1 million) in connection with the TPG credit facility,
the Citibank credit facility and the related guaranties. We have reimbursed TPG
for all its fees and disbursements of legal counsel, financial advisors and
other third party consultants (of approximately $14 million) and have paid other
out-of-pocket expenses incurred by us in connection with the restructuring (of
approximately $3 million).

OWNERSHIP INTEREST IN TPG WAFER MANAGEMENT


     Certain of our executive officers have received limited liability company
membership interests in TPG Wafer Management, an investment limited liability
company that owns a 1.5% membership interest in TPG Wafer Holdings. These
membership interests are economic interests, with no voting rights and represent
a total of approximately 57% of the interests in TPG Wafer Management and,
therefore, indirectly, approximately 0.86% of the membership interests in TPG
Wafer Holdings.


     Additional membership interests in TPG Wafer Management may be issued to
directors, executive officers and other services providers of MEMC. In addition
to its membership interest in TPG Wafer Holdings, TPG Wafer Management owns
approximately $750,000 in principal amount of our senior secured notes and a
1.5% interest in the 55 million Euro note issued by MEMC's Italian subsidiary as
well as 250,000 of our warrants. Upon consummation of the merger described
above, TPG Wafer Management will receive a proportionate amount of the shares of
common stock, preferred stock and/or warrants of MEMC in exchange for its 1.5%
membership interest in TPG Wafer Holdings. Assuming consummation of the merger
on November 13, 2001, TPG Wafer Management would have received 749,399 shares of
MEMC common stock and 3,900 shares of Series A Preferred Stock.

              ITEM NO. 2 -- APPROVAL OF 2001 EQUITY INCENTIVE PLAN

     MEMC's Board of Directors adopted MEMC's 2001 Equity Incentive Plan on
December 10, 2001, amended and restated the plan effective in March, 2002, and
directed that the plan be presented for approval by stockholders at MEMC's 2002
Annual Shareholders' Meeting.

GENERAL

     The purpose of the plan is to promote the interests of MEMC and its
stockholders by providing prospective employees, employees and consultants of
MEMC and its subsidiaries with an appropriate incentive to enter and continue in
the employ of MEMC and to improve the growth and profitability of MEMC.

     The Compensation and Nominating Committee administers the plan. The plan
provides for the grant of nonqualified stock options and restricted stock.
Individuals who are prospective employees of, employees of or

                                        33


consultants to MEMC or a subsidiary of MEMC are eligible to receive awards under
the plan. The Compensation and Nominating Committee has discretion to, among
other things:

     - Determine whether to grant nonqualified stock options, restricted stock
       or a combination of both

     - Select the prospective employees, employees and consultants to whom
       awards are made

     - Establish the timing, pricing, amount, vesting and other terms and
       conditions of each award

     - Adopt, amend and rescind rules and regulations relating to the plan

     - Construe and interpret the plan and award agreements

     - Make all other determinations necessary or advisable for the
       administration of the plan

     The Compensation and Nominating Committee's decisions pertaining to the
interpretation, construction or application of the plan are final and binding.


     Subject to certain adjustments, a maximum of 7,000,000 shares of common
stock are available for grant under the plan, of which 5,146,410 shares had been
granted as of March 31, 2002. These shares may be authorized but unissued
shares, treasury shares or any combination thereof. If any award granted under
the plan terminates or expires prior to its exercise, the shares covered by the
award will again be available for grant under the plan. No more than 2,000,000
shares of common stock may be subject to stock options awarded in any calendar
year to an individual subject to Section 162(m) of the Internal Revenue Code of
1986, as amended.


     The closing price of MEMC common stock on March 28, 2002 as reported on the
New York Stock Exchange was $5.90 per share. As of March 31, 2002, there were
approximately 4,600 employees and 70 consultants who were potentially eligible
to participate in the plan.

TYPES OF AWARDS

     Set forth below is a description of the types of awards that may be granted
under the plan.

  NONQUALIFIED STOCK OPTIONS

     Under the plan, the Compensation and Nominating Committee may grant
nonqualified stock options pursuant to an award agreement. Each option
represents the right to purchase one share MEMC common stock at a price per
share established by the Compensation and Nominating Committee on the date of
grant.

     Options must be exercised before expiration or termination, which is
generally ten years after the date of grant or earlier as a result of death,
disability or other termination of employment or consulting service with MEMC.

  RESTRICTED STOCK

     The Compensation and Nominating Committee may award restricted stock under
the plan pursuant to an award agreement. Restricted stock is an award of MEMC
common stock that is subject to restrictions determined by the Compensation and
Nominating Committee, including forfeiture conditions and restrictions against
transfer for a specified period. The restrictions on restricted stock may lapse
in installments based on factors determined by the Compensation and Nominating
Committee. In addition, the Compensation and Nominating Committee has discretion
to waive or accelerate the lapsing of restrictions in whole or in part.

     Prior to the expiration of the restricted period, a grantee of restricted
stock has the right to vote the restricted stock and, unless otherwise provided
in the award agreement, the right to receive cash dividends on the restricted
stock. Any stock dividends on shares of restricted stock will be treated as
additional shares under the restricted stock award and will be subject to the
same restrictions and other terms and conditions as the restricted stock on
which the stock dividend was paid.

                                        34


     Restricted stock that is not vested at the time a grantee's employment or
consulting service is terminated for any reason will be forfeited, unless
otherwise specified in the award agreement.

ADDITIONAL INFORMATION

  CHANGE IN CAPITALIZATION

     Under the plan, if there is a change in the number of outstanding shares of
MEMC common stock by reason of any stock dividend, recapitalization, merger,
consolidation, stock split, combination or exchange of shares or other form of
reorganization, or any other change involving MEMC common stock, proportionate
adjustments will be made under the plan to reflect the change. Adjustments with
respect to the following will be made as considered appropriate by the
Compensation and Nominating Committee to prevent dilution or enlargement of
rights:

     - The aggregate number of shares of MEMC common stock for which awards may
       be granted under the plan

     - The number of shares of MEMC common stock covered by each outstanding
       award under the plan and the price per share for each such award

     In the event any of the following events occur, the Compensation and
Nominating Committee may in its discretion exchange or cancel any outstanding
award in return for a new award, cash and/or the property received by holders of
MEMC common stock:

     - Dissolution or liquidation of MEMC

     - Sale of all or substantially all of MEMC's assets

     - Merger or consolidation involving MEMC where MEMC is not the surviving
       corporation

     - Merger or consolidation involving MEMC where MEMC is the surviving
       corporation but the holders of shares of MEMC common stock receive
       securities of another corporation and/or other property, including cash

  CHANGE IN CONTROL

     In the event an individual's employment or consulting service is terminated
by MEMC without cause or by such individual for good reason within two years
following a change in control of MEMC, then, unless the award agreement
otherwise provides or the Compensation and Nominating Committee otherwise
determines:

     - All outstanding options held by such individual will become fully vested
       and exercisable

     - All restrictions and conditions of all restricted stock awards then
       outstanding will lapse

  OTHER TERMS

     Generally, an individual's rights under the plan may not be assigned or
transferred except in the event of death.

     The plan will remain in effect until terminated by the Compensation and
Nominating Committee. The plan will continue thereafter, however, until all
awards previously granted under the plan are satisfied or otherwise terminated.
Unless the plan is amended or terminated by the Compensation and Nominating
Committee, no awards may be granted under the plan after December 7, 2011.

     The Compensation and Nominating Committee may in its discretion terminate
any option or restricted share then outstanding without amendment to the plan or
the award agreement and pay to the holder thereof:

     - With respect to options, an amount equal to the excess of the then fair
       market value of MEMC common stock over the exercise price of the options

                                        35


     - With respect to restricted stock, an amount equal to the then fair market
       value of MEMC common stock

     The Compensation and Nominating Committee may at any time amend, suspend or
terminate the plan. No amendment, suspension or termination, however, may
adversely affect a grantee's rights under any previously granted award without
the consent of the grantee.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of certain of the federal income tax
consequences to holders of nonqualified stock options granted under the plan.

  NONQUALIFIED STOCK OPTIONS

     Although an optionee will not recognize income upon the original grant of a
nonqualified stock option, if an optionee chooses to exercise his or her option,
the optionee will recognize ordinary income in an amount equal to the difference
between the fair market value of the shares of MEMC common stock on the date of
exercise and the aggregate exercise price for such shares. To the extent, and in
the year, that an optionee recognizes income, MEMC may take a deduction. An
optionee's tax basis in the shares received will equal the fair market value of
such shares on the date of exercise.

     If an optionee disposes of shares purchased pursuant to a nonqualified
stock option, any gain or loss will be short-term or long-term capital gain or
loss, depending upon the period during which the optionee held such shares. See
"Capital Gains and Losses" below. No gain or loss will be recognized on the
surrender of the previously acquired shares. If an optionee surrenders
previously acquired shares to pay for a nonqualified stock option, the excess,
if any, of the fair market value of the newly acquired shares over the fair
market value of the surrendered shares will be includable in the optionee's
income.

  CAPITAL GAINS AND LOSSES

     If an optionee holds shares for more than twelve months, upon a subsequent
disposition, the optionee will realize long-term capital gain or loss equal to
the difference between the amount the optionee receives upon such disposition
and the optionee's basis in the shares.

     If an optionee disposes of shares twelve months or less after the optionee
acquires them, the optionee will realize short-term capital gain or loss equal
to the difference between the amount the optionee receives upon such disposition
and the optionee's basis in the shares.

     To the extent that an optionee recognizes ordinary income, MEMC may take a
deduction.

      THE MEMC BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF
                       MEMC'S 2001 EQUITY INCENTIVE PLAN.

                 SHAREHOLDER PROPOSALS FOR 2003 ANNUAL MEETING


     Shareholder proposals intended to be presented at our 2003 Annual
Shareholders' Meeting must be received by us by January 20, 2003 for inclusion
in our proxy statement and form of proxy card for that meeting.


     In order for a shareholder to nominate a candidate for director for
election at an annual shareholders' meeting, under our Restated Certificate of
Incorporation, we must receive timely notice of the nomination in advance of the
meeting. Such notice must be given not less than 90 nor more than 120 days prior
to the anniversary date of the immediately preceding annual shareholders'
meeting. The shareholder filing a notice of nomination must include information
about the nominee, such as name, address, occupation and shares held.

     In order for a shareholder to bring other business before an annual
shareholders' meeting, we must receive timely notice in advance of the meeting.
Such notice must be given not less than 90 nor more than 120 days prior to the
anniversary date of the immediately preceding annual shareholders' meeting. The
notice must include a description of the proposed business, the reasons
therefor, and other specified matters. These requirements are separate from and
in addition to the requirements a shareholder must meet to have a proposal
included in our proxy statement. Upon receipt of any such proposal, we will
determine whether or not to include such proposal in the proxy statement, form
of proxy card and/or annual shareholders' meeting agenda under regulations
governing the solicitation of proxies. The above time limits also apply in
determining whether notice is timely for purposes of rules adopted by the
Securities and Exchange Commission relating to the exercise of discretionary
voting authority.

     In each case, the notice must be given to David Fleisher, MEMC's Secretary,
whose address is 501 Pearl Drive (City of O'Fallon), P. O. Box 8, St. Peters,
Missouri 63376.

     Any shareholder desiring a copy of our Restated Certificate of
Incorporation or Restated By-Laws will be furnished a copy without charge upon
written request to our Secretary.

                                 OTHER MATTERS

     The Board of Directors knows of no other matters to be presented for
consideration at the 2002 Annual Shareholders' Meeting by the Board of Directors
or by shareholders who have requested inclusion of proposals in this proxy
statement. If any other matter shall properly come before the meeting, the
persons named in the accompanying proxy card intend to vote on such matters in
accordance with their judgment.
