                MEMC ELECTRONIC MATERIALS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                    (Dollars in thousands, except share data)

(1)  Basis of Presentation
     The  accompanying  unaudited  consolidated  financial  statements  of  MEMC
     Electronic  Materials,  Inc. and Subsidiaries (the Company), in the opinion
     of management,  include all  adjustments  (consisting of normal,  recurring
     items)  necessary to present  fairly the Company's  financial  position and
     results  of  operations  and cash  flows  for the  periods  presented.  The
     consolidated  financial  statements  are presented in  accordance  with the
     requirements  of  Regulation  S-X  and  consequently  do  not  include  all
     disclosures required by generally accepted accounting principles. Operating
     results  for the three and  six-month  periods  ended June 30, 1998 are not
     necessarily  indicative  of the results  that may be expected  for the year
     ending December 31, 1998.

(2)  Restructuring Costs
     During the second quarter of 1998,  the Company  decided to close its small
     diameter wafer facility in Spartanburg, South Carolina and to withdraw from
     the  Company's  joint venture  participation  in the small  diameter  wafer
     operations   in   China.   In  order  to  gain   production   efficiencies,
     semiconductor  manufacturers  have  increased  their use of large  diameter
     manufacturing  lines in preference to small diameter lines. In addition,  a
     number   of   semiconductor    manufacturers   recently   have   undertaken
     restructuring initiatives focused on permanently eliminating small diameter
     lines.  The  combination  of these  developments  in the  industry  led the
     Company to conclude that its small  diameter  wafer  capacity  would exceed
     demand even after the  semiconductor  market begins to recover.  Therefore,
     the decisions concerning Spartanburg and the China joint venture were made.

     The Company also decided to forego  construction  of a new eight inch wafer
     facility in Malaysia. This decision is based upon industry overcapacity and
     the resultant price erosion for eight inch wafers.

     The Company  recorded a charge to operations  during the second  quarter of
     $114,800  (of which  $78,100 is  non-cash)  related  to the above  actions,
     comprised of the following:

                  Asset impairment/write-off          $ 78,100
                  Dismantling costs                     24,500
                  Personnel costs                       12,200
                                                       -------
                                                      $114,800
                                                       =======

     The assets for which an impairment  loss has been  recorded,  or which have
     been written off entirely, are primarily property, plant and equipment that
     cannot  be  sold  or  used  at  other  Company  manufacturing   facilities.
     Accordingly,  these assets have been written down to net realizable  value.
     Additionally,   the  Company  wrote  off  architectural   design  and  site
     preparation  fees and  costs  incurred  to  develop a  computer  integrated
     manufacturing  system for the Malaysian site that do not have applicability
     elsewhere within the Company.

     The provision for dismantling  costs relates to the Spartanburg  production
     facility and includes  estimates for the removal of  production  equipment,
     dismantling of the facility,  collection and disposal of process chemicals,
     decontamination  of  manufacturing  equipment,  shutdown of the  wastewater
     treatment facility, freight and scrapping charges.

     Personnel costs represent the expected cost of involuntary terminations for
     approximately  900 hourly and salaried  employees whom the Company does not
     expect to relocate elsewhere within the organization.

     In addition to the  restructuring  activities  discussed above, the Company
     recorded a $16,600 charge to complete the voluntary  separation program for
     approximately  600 hourly and  salaried  U.S.  employees  that began in the
     first quarter of 1998.  Substantially all this amount was paid to employees
     as of June 30, 1998.  The total charge to  operations  for this program was
     $24,600,  which includes an $8,000  provision made during the first quarter
     of 1998.

     These restructuring activities are expected to be implemented over the next
     12 months.  During this time the Company will  transfer the small  diameter
     production activities of the Spartanburg facility to other existing Company
     locations.  Estimated  pre-tax  savings as a result of these  restructuring
     activities and the voluntary  separation  plan are $60,000 on an annualized
     basis. One-half of the estimated savings will begin in the third quarter of
     1998  through  reduced  personnel  costs  as  a  result  of  the  voluntary
     separation  program.  The remainder of the  annualized  savings  relates to
     personnel   costs   and   manufacturing   costs,   such  as   depreciation,
     manufacturing  supplies and utilities.  The time frame for achieving  these
     savings will depend upon such factors as the transfer of  Spartanburg-based
     customer  orders to other  wafer  facilities  within  the  Company  and the
     willingness  of these  customers to  re-qualify  at other sites,  but these
     savings will begin in the third quarter of 1998.

 (3) Earnings (loss) per share
     The numerator for basic and diluted  earnings (loss) per share  calculation
     is net earnings (loss) for all periods  presented.  The denominator for the
     basic and diluted  earnings (loss) per share  calculation for the three and
     six-month  periods ended June 30, 1998 are the same (the  weighted  average
     shares outstanding for each respective period) due to the net loss incurred
     during each period.  A  reconciliation  of weighted  average shares for the
     basic and diluted  earnings (loss) per share  calculation for the three and
     six-month periods ended June 30, 1997 are as follows:

                                                 Three Months       Six Months
                                                Ended June 30,    Ended June 30,

(5)  Comprehensive Income
     Effective  January 1, 1998,  the Company  adopted  Statement  of  Financial
     Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income." SFAS
     No.  130  requires  all items  that are  required  to be  recognized  under
     accounting standards as components of comprehensive income be reported in a
     financial  statement  that is displayed  with the same  prominence as other
     financial statements.  All comparative information has been reclassified to
     conform to the current year presentation.

     Comprehensive  loss for the three and six-month periods ended June 30, 1998
     was  $149,650  and  $181,380,  respectively.  For the three  and  six-month
     periods ended June 30, 1997, the Company had comprehensive income of $6,993
     and  a  comprehensive   loss  of  $10,610,   respectively.   The  Company's
     comprehensive  loss  is  impacted  only  by  foreign  currency  translation
     adjustments.


Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

Net Sales.  Net sales  decreased  17.8% to $202.2  million for the three  months
ended June 30,  1998,  from $245.8  million for the three  months ended June 30,
1997.  Product volume declined 5.5% in the 1998 second quarter over the year ago
period due to weakening demand for smaller diameter wafers,  partially offset by
a 23.8% increase in eight inch product volume.  On a geographic  basis,  product
volumes decreased most significantly in the United States,  followed by the Asia
Pacific region,  while Japan was essentially flat and Europe  experienced strong
volume growth compared to the second quarter of 1997.

Net sales for the six month period ended June 30, 1998  decreased 6.6% to $437.4
million from $468.1 million for the comparable period.  Product volume increased
4.4%  for the  first  half of 1998  over  the  year-ago  period,  led by a 38.4%
increase  in eight  inch  volume,  partially  offset by volume  declines  in all
smaller diameter wafers.  Volume increases by geographic  region were highest in
Europe,  followed by Japan. Sales to the Asia Pacific region were flat, and were
slightly lower in the United States.

Excess capacity in the semiconductor  industry,  particularly DRAMs,  continuing
problems  and  weakness  in the Asian and  Japanese  economies,  and lower  than
expected PC sales have caused  product  volumes in the silicon wafer industry to
decline  over the past two  quarters.  These  factors,  in  addition  to  excess
capacity in the silicon wafer  industry,  have caused average  selling prices to
decline significantly since the beginning of 1997. As the Company believes these
industry  conditions  are  likely  to  persist  in the near  term,  the  Company
anticipates that product volumes and pricing will continue to weaken in the 1998
third quarter,  and that the Company's  significant excess capacity will persist
through 1999.

Gross Margin.  Gross margin declined from 12.5% in the second quarter of 1997 to
a negative 1.9% for the second  quarter of 1998.  The decline in gross margin is
primarily attributable to continuing pressure on prices, especially for advanced
large diameter wafers,  and lower product volume.  For the six months ended June
30, 1998,  gross margin was 4.6%, as compared to 12.6 % for the year-ago period.
The  decline  in  gross  margin  for  the  first  six  months  of  1998  is also
attributable  to falling prices,  partially  offset by an increase in eight inch
product volume and improved product mix.

Advanced  large  diameter  and  epitaxial  products  represented  45% and 39% of
product volume for the three months ended June 30, 1998 and 1997,  respectively.
The increase in eight inch product volume is a result of the Company's customers
running larger diameter production lines in preference to smaller diameter lines
in order to gain  production  efficiencies  during  the  semiconductor  industry
downturn.

Marketing  and  Administration.  Marketing and  administration  costs were $18.9
million for the second quarter of 1998, a 12.2% increase over the second quarter
of 1997. For the six month period,  marketing and administration costs increased
$2.5 million,  or 7.2%,  over the same period in 1997. The increase in marketing
and  administration  costs  for both the  three  and  six-month  periods  is due
primarily to expenses associated with redesign of the Company's business systems
as part of a worldwide SAP implementation that began in 1998.

Research and  Development.  Research and  development  costs rose 12.0% to $17.7
million for the three months ended June 30, 1998,  as compared to $15.8  million
for the year-ago period. Research and development costs increased 29.4% to $37.8
million  for the  six-month  period as  compared  to the  year-ago  period.  The
increase  is due to  continuing  investments  in the  Company's  12  inch  wafer
development  program. The expenses for this program are anticipated to rise as a
result  of  depreciation  associated  with the  installation  of  equipment  and
start-up of the Company's 12 inch  integrated  development  line in  Utsunomiya,
Japan.

Restructuring  Costs.  Because of  developments in the  semiconductor  industry,
including the increased use of large  diameter  lines by  manufacturers  and the
focus on permanent  elimination  by some  manufacturers  of small wafer diameter
lines,  during the second quarter of 1998 the Company decided to close its small
diameter wafer facility in Spartanburg,  South Carolina and to withdraw from the
Company's joint venture  participation in the small diameter wafer operations in
China.   These  decisions  were  made  principally   because  of  the  Company's
determination  that even after the semiconductor  market begins to recover,  the
Company  will have excess  small  diameter  wafer  capacity in light of industry
developments.  In an effort to control  further excess capacity of the Company's
large diameter wafer facilities,  the Company also decided in the second quarter
to forego construction of a new eight inch wafer facility in Malaysia.

These actions  resulted in a charge to operations  during the second  quarter of
$114.8 million (of which $78.1 million is non-cash),  comprised of $78.1 million
for asset  impairments,  $24.5 million in dismantling costs and $12.2 million in
personnel  related  costs.  The  assets  for which an  impairment  loss has been
recorded or which have been written off entirely are primarily  property,  plant
and  equipment  which  cannot be sold or used at other  Company  facilities.  In
addition,  the Company wrote off architectural  design and site preparation fees
as well as costs incurred to develop a computer integrated  manufacturing system
for  the  Malaysian  site.  Personnel  costs  represent  the  expected  cost  of
involuntary  terminations for  approximately  900 hourly and salaried  employees
whom the Company does not expect to relocate  elsewhere within the organization.
See Note 2, Notes to Consolidated Financial Statements, above.

Also in the second quarter of 1998, the Company  recorded a $16.6 million charge
to complete the voluntary  separation  program for  approximately 600 hourly and
salaried  U.S.  employees  that began in the first  quarter  of 1998.  The total
charge to operations for this program was $24.6 million,  which includes an $8.0
million provision made during the first quarter of 1998.

Management  expects that the  restructuring  activities  discussed above will be
implemented over the next 12 months. During this time, the Company will transfer
the small diameter  production  activities of the Spartanburg  facility to other
Company locations.  Estimated pre-tax savings as a result of these restructuring
activities  and the voluntary  separation  plan are $60 million on an annualized
basis.  One-half of the  estimated  savings  are  expected to begin in the third
quarter of 1998 through  reduced  personnel  costs as a result of the  voluntary
separation program. The remainder of the annualized savings relates to personnel
costs and manufacturing costs, such as depreciation,  manufacturing supplies and
utilities.  The time frame for  achieving  these  savings  will depend upon such
factors as the transfer of the Spartanburg-based  customer orders to other wafer
facilities  within  the  Company  and the  willingness  of  these  customers  to
re-qualify at other sites,  but these savings will begin in the third quarter of
1998.  The  Company's  ability  to  achieve  the  projected  savings  is in part
dependent  upon the accuracy of certain  assumptions,  including  replacement of
terminated  employees and the cost of producing  small diameter  wafers at other
facilities.

Interest  Expense.  Interest  expense totaled $9.0 million and $17.3 million for
the three and six-month periods ended June 30, 1998, respectively as compared to
$1.3 million for each of the three and six-month  periods of 1997.  The increase
in  interest  expense is due to the  completion  of capital  projects  for which
interest costs could no longer be capitalized and increased borrowings.

Other,  Net. Other,  net decreased  approximately  $10 million for the three and
six-month  periods ended June 30, 1998 as compared to the same periods for 1997,
primarily  due to the sale of the  Company's  Santa Clara wafer  facility in May
1997 that resulted in a pre-tax gain of $6.0 million.

Income Taxes.  The effective  income tax rate was 22.4% for the first six months
of 1998, as compared to 43.0% for the same period of 1997.  This  fluctuation is
the result of changes in the composition of worldwide pretax income,  certain of
the   restructuring   costs  that  are  not  deductible  for  tax  purposes  and
non-deductible operating expenses at the Malaysian and Chinese joint ventures.

Equity  in Loss of Joint  Ventures.  Equity in loss of joint  ventures  was $5.3
million in the second  quarter of 1998, as compared to a loss of $1.7 million in
the  year-ago  period.  The loss in the  second  quarter  of 1998  includes  the
write-off of certain  deferred tax assets  totaling $5.4 million at Taisil,  the
Taiwan joint  venture,  which are not  anticipated  to be utilized  prior to the
initiation of a tax holiday beginning in 2000. This write-off was almost equally
offset by $5.2 million in foreign  currency gains on Korean won exposure at PHC,
the Korean joint venture, and New Taiwanese dollar exposure at Taisil. Excluding
the write-off and currency  gains,  equity in loss of joint  ventures would have
been $5.1 million in the second  quarter of 1998,  reflecting  lower volumes and
prices at PHC, and lower prices at Taisil.

For the six months  ended June 30,  1998,  equity in loss of joint  ventures was
$15.4  million,  a $11.9 million  increase over the first six months of 1997. In
addition to the deferred tax asset write-off  discussed above, equity in loss of
joint  ventures  includes  $2.2  million in net  currency  losses for both joint
ventures  for the first half of 1998.  Excluding  the impact of currency and the
deferred tax asset  write-off,  equity in loss of joint ventures would have been
$7.8 million for the six months ended June 30, 1998.  This  decrease as compared
to the year-ago period is due to the lower volumes and prices at PHC and Taisil.

Liquidity and Capital Resources. At June 30, 1998, the Company had cash and cash
equivalents  of $16.8  million.  The  Company's  borrowings  against  its $936.1
million of credit  facilities were $779.0 million at June 30, 1998.  Outstanding
borrowings increased $146.5 million from December 31, 1997 to June 30, 1998, the
proceeds of which have been used to finance the Company's  capital  expenditures
and working capital requirements.  The Company's weighted-average borrowing rate
was 6.0% at June 30, 1998.

A comparison  of the  components of the Company's  financial  condition  follows
(dollars in millions):

                                          June 30,         December 31,

                                            ----               ----
Working capital                            $ (2.1)           $  38.4
Current ratio                             1.0 to 1           1.1 to 1
Stockholders' equity                      $ 501.5            $ 698.5
Total debt to total capitalization          58.3%              45.5%
                                            ====               ====

The Company's  primary  sources of liquidity  historically  have been cash flows
from  operating  activities  and  borrowings  from  affiliates  and, to a lesser
extent,  from third parties.  The Company's  principal uses of cash have been to
support its operating  activities,  capital expenditures and equity infusions in
joint ventures.  The Company's  capital  expenditures  and its recent  operating
performance have resulted in significant negative cash flow.

Cash flows used in operating  activities  were $37.4  million for the six months
ended  June  30,  1998  compared  to $2.9  million  of cash  flows  used for the
comparable  1997  period.  Operating  cash flow was  negatively  impacted by the
results of  operations  for the period,  a decrease  in accounts  payable due to
lower  capital  expenditures  than in the prior period,  a non-cash  increase in
deferred  taxes  due to net  operating  loss  carryforwards  generated  in 1998,
partially  offset by non-cash items such as the  restructuring  charge  recorded
during  the  1998  second  quarter,  depreciation  and  equity  in loss of joint
ventures.

Cash flows used in investing  activities  for the six months ended June 30, 1998
included  capital  expenditures  of $107.9  million,  which  represents  a $67.2
million  reduction  from the first six months of 1997. The Company had committed
capital  expenditures of $95.8 million as of June 30, 1998. Capital expenditures
for the first half of 1998 primarily  relate to equipping the 12 inch pilot line
in St. Peters,  Missouri, the 12 inch integrated development line in Utsunomiya,
Japan and the  polysilicon  expansion at MEMC  Pasadena.  Given  current  market
conditions,   the  Company   anticipates  that  capital   expenditures  will  be
approximately $220 million for fiscal year 1998.

Cash flows from financing  activities were  essentially  flat as compared to the
1997 six-month  period,  although the 1998 period includes higher  long-term and
lower  short-term  borrowings than in 1997, and the repurchase of 893,000 shares
of the Company's common stock totaling $15.7 million during the first quarter of
1998.

The  Company's  liquidity  and cash flow are being  negatively  impacted  by the
Company's  operating  losses  caused by excess  capacity and  declining  prices,
increasing  research and  development  costs and interest  expense,  and capital
expenditures.  As a result, the Company could experience difficulty in obtaining
additional credit facilities from unrelated third parties on terms acceptable to
the Company.  Management currently believes that cash generated from operations,
together  with the  liquidity  provided by  existing  cash  balances  and credit
facilities will be insufficient to satisfy commitments for capital  expenditures
and other cash requirements for the next twelve months. Accordingly, the Company
is discussing with its principal  stockholder and related affiliates  additional
financing and the  restructuring of existing credit  facilities.  Although there
can be no assurance,  management believes it can obtain sufficient  financing to
meet its cash requirements for the next 12 months.

Year 2000. Many computer systems  experience  problems handling dates beyond the
year 1999.  Many  existing  computer  programs only use two digits to identify a
year in the date field.  Such systems and programs  must be modified or replaced
prior to  January  1,  2000 in order  to  remain  functional.  The  Company  has
undertaken  a  company-wide  Year 2000  project,  staffed with a diverse team of
personnel  representing all levels of the Company's operations and headed by the
Company's Executive Vice President and Chief Financial Officer.  The Company has
also  retained  an  outside  consulting  firm to assist in  ensuring  the proper
project  structure is put in place and that the requisite  level of awareness of
the Year 2000 issue is across all levels of the  Company.  These early phases of
the project are  complete,  a project  structure is in place and the Company has
now entered the remediation,  testing and implementation  phases of the project.
All sites are at different  stages of  completion.  The goal of management is to
have all systems and equipment Year 2000 ready by June 1999 and critical systems
and process equipment ready by 1998 year end.

In addition,  some Year 2000  exposures  relate to the  Company's  suppliers and
customers.  The Company has identified  its key suppliers and business  partners
and has sent out initial  requests for information on their Year 2000 compliance
status.  The Company has dedicated  resources to monitor these parties' progress
as they address the Year 2000 issue. Additional requests will be sent, responses
tracked  and  contingency  plans  developed  as  required  to address  potential
failures of these parties to be Year 2000 ready.

Failure by the Company and/or the third parties with whom it does business to be
prepared  for and  properly  address  the Year 2000 issue  could have a material
adverse effect on the Company and its ability to conduct  business.  The Company
expects to implement  successfully the systems and programming changes necessary
to address  the Year 2000 issue and does not  believe  the cost of such  actions
will have a material adverse effect on the Company, its results of operations or
financial condition.

Recently  Issued  Accounting   Pronouncements.   In  June  1998,  the  Financial
Accounting  Standards Board issued Statement of Financial  Accounting  Standards
(SFAS) No. 133, "Accounting for Derivative  Instruments and Hedging Activities."
SFAS  No.  133  requires  the  recognition  of  all  derivatives  as  assets  or
liabilities  within the balance sheet, and requires both the derivatives and the
underlying  exposure to be recorded  at fair value.  Any gain or loss  resulting
from  changes  in  fair  value  will be  recorded  as  part  of the  results  of
operations,  or as a component of comprehensive  income or loss,  depending upon
the intended  use of the  derivative.  SFAS No. 133 is effective  for all fiscal
quarters of fiscal years  beginning after June 15, 1999. The Company has not yet
determined the impact of this Statement.

This Form 10-Q contains  "forward-looking"  statements within the meaning of the
Securities Litigation Reform Act of 1995, including those concerning the manner,
timing and  estimated  savings of  restructuring  activities  and the  voluntary
separation  program,  transfer of  Spartanburg-based  small diameter  production
activities to other existing locations, product volume and pricing for the third
quarter of 1998,  excess  capacity  through  1999,  increases  in  research  and
development  expenses,  capital  expenditures for 1998, the Company's ability to
secure financing in the future on terms acceptable to the Company, liquidity for
the  next  twelve  months  and  the  successful   implementation  of  Year  2000
initiatives.  Such statements involve certain risks and uncertainties that could
cause  actual  results to differ  materially  from those in the  forward-looking
statements. Potential risks and uncertainties include such factors as the demand
for the Company's  wafers,  utilization of  manufacturing  capacity,  demand for
semiconductors generally,  changes in the pricing environment,  general economic
conditions in Asia and Japan, competitors' actions,  willingness of customers to
re-qualify Spartanburg-based production at other Company locations,  accuracy of
assumptions  regarding  savings from  restructuring  activities,  success of the
Company's  discussions  with its principal  stockholder  and related  affiliates
concerning  financing matters and other risks described in the Company's filings
with the Securities and Exchange  Commission,  including the report on Form 10-K
for the year ended December 31, 1997.

                       FIRST AMENDMENT TO CREDIT AGREEMENT

     This First Amendment to Credit Agreement  ("First  Amendment") is effective
as of  July  1,  1998  between  MEMC  ELECTRONIC  MATERIALS,  INC.,  a  Delaware
corporation,  as the Borrower,  and HULS AG, a company  formed under the laws of
the Federal Republic of Germany ("Huls"), as the sole Lender and as Agent.

                                    Recitals

     WHEREAS, Borrower and Huls entered into a Credit Agreement dated as of July
10, 1995 (the "Credit Agreement")  pursuant to which Huls agreed to extend up to
US $25,000,000 of credit to Borrower on a term basis; and

     WHEREAS,  Borrower and Huls desire to amend the Credit  Agreement to extend
the final maturity date of the US $25,000,000  term credit facility to September
30, 1998 and to change the interest rate payable by Borrower to Huls during such
extension period.

     NOW THEREFORE,  in consideration  of the foregoing  premises and the mutual
covenants and conditions hereinafter set forth, the parties agree as follows:

     1. The definition of "Final Maturity Date" set forth in Section 1.01 of the
Credit  Agreement is deleted in its entirety and the following is substituted in
lieu thereof:

                 "Final Maturity Date" means September 30, 1998.

     2. Section  2.06(a) of the Credit  Agreement is deleted in its entirety and
the following is substituted in lieu thereof:

          (a) Interest on the Advances.  The Borrower  shall pay interest on the
          unpaid principal amount of the Advances,  if any, from the date of the
          Advances  until such principal  amount shall be paid in full,  payable
          semiannually,  at an interest rate per annum equal to 7.12%; provided,
          however,  that as of the date  occurring  45  Business  Days after the
          Change of Control Date,  the interest rate per annum shall be the Base
          Rate in effect for such Advances plus the Applicable Margin.

     3. Section 5.02 of the Credit  Agreement is deleted in its entirety and the
following is substituted in lieu thereof:

          SECTION 5.02. Negative Covenants.

          (a) Accounting Changes. On and after the Change of Control Date and so
          long as any Advance  shall remain  unpaid or any Lender shall have any
          Commitment hereunder,  the Borrower will not, unless the Lenders shall
          otherwise  consent in  writing,  make or permit,  or permit any of its
          Subsidiaries to make or permit,  any change in accounting  policies or
          reporting   practices,   except  as  allowed  by  generally   accepted
          accounting principles.

          (b) Liens,  etc.  On and after July 1, 1998 and so long as any Advance
          shall remain unpaid or any Lender shall have any Commitment hereunder,
          the Borrower will not, unless the Lenders shall  otherwise  consent in
          writing,  create or suffer to exist, or permit any of its Subsidiaries
          to create or suffer to exist,  any lien,  security  interest  or other
          charge or encumbrance,  or any other type of preferential arrangement,
          upon or with  respect to any of its  properties,  whether now owned or
          hereafter  acquired,  or assign,  or permit any of its Subsidiaries to
          assign,  any right to receive income,  in each case to secure any Debt
          of any Person, other than:

               (i) purchase  money liens or purchase  money  security  interests
               upon or in any  property  acquired or held by the Borrower or any
               Subsidiary  in the  ordinary  course of  business  to secure  the
               purchase  price  of  such  property  or  to  secure  indebtedness
               incurred  solely for the purpose of financing the  acquisition of
               such property;

               (ii) liens or security interests existing on such property at the
               time of its  acquisition  (other  than any such lien or  security
               interest created in contemplation of such acquisition);

               (iii)  liens for taxes,  assessments  and  government  charges or
               levies  to the  extent  not  required  to be paid  under  Section
               5.01(b) hereof:

               (iv) liens  imposed by law,  such as  materialmen's,  mechanics',
               carriers',  workmen's  and  repairmen's  liens and other  similar
               liens  arising  in  the  ordinary  course  of  business  securing
               obligations  that are not  overdue  for a period  of more than 30
               days;

               (v)  pledges or  deposits to secure  obligations  under  workers'
               compensation  laws or similar  legislation or to secure public or
               statutory obligations;

               (vi) easements,  rights of way and other encumbrances on title to
               real property that do not render title to the property encumbered
               thereby  unmarketable or materially  adversely  affect the use of
               such property for its present purposes; and

               (vii) liens  incurred or deposits made in the ordinary  course of
               business to secure the  performance  of letters of credit,  bids,
               tenders, sales contracts,  leases, surety, appeal and performance
               bonds and other  similar  obligations  not incurred in connection
               with the borrowing of money.

     4. Unless otherwise provided herein, any term in initial capital letters or
all  capital  letters  used as a  defined  term but not  defined  in this  First
Amendment shall have the meaning set forth in the Credit Agreement.

     5.  Except as  modified  herein,  all terms and  conditions  of the  Credit
Agreement shall remain in full force and effect.

     IN WITNESS  WHEREOF,  the parties to this First Amendment have caused it to
be executed by their duly authorized representatives effective as of the day and
year first above written.  This First Amendment may be executed in counterparts,
each of which  shall be  deemed an  original,  but all of which  together  shall
constitute one and the same instrument.

                             SPECIAL INCENTIVE PLAN
                                     SUMMARY

In March 1998, the Company  adopted a special  incentive plan designed to retain
the services of certain officers and key employees during the period  commencing
April 1, 1998 and  ending  June 30,  1999 (the  "Retention  Period").  Under the
special  incentive plan, the  participants  received a special  incentive bonus.
Fifty percent (50%) of the special  incentive bonus (the "Advance  Payment") was
paid  to each  participant  at the  time  the  participant  executed  a  special
incentive bonus agreement with the Company. The remaining fifty percent (50%) of
each  participant's  special  incentive  bonus  will be paid  on June  30,  1999
provided that such  participant  remains an employee of the Company through June
30, 1999.

In the event a participant  terminates  his or her  employment  with the Company
prior to April 1,  1999,  the  incentive  bonus  agreement  provides  that  such
participant must reimburse the Company the entire amount of the Advance Payment.
Notwithstanding  the  foregoing,  no  reimbursement  of the  Advance  Payment is
required  in the  event of the  death or total  and  permanent  disability  of a
participant,  or in the event a  participant's  employment  with the  Company is
involuntarily  terminated  by the  Company as a result of a change in control of
the Company or a reduction in the Company's workforce.

In the event a participant  terminates  his or her  employment  with the Company
after March 31,  1999 and before July 1, 1999,  the  incentive  bonus  agreement
provides that such  participant must reimburse the Company a pro rata portion of
the Advance  Payment (such  reimbursement  based on the portion of the Retention
Period  during  which  the  participant  failed to  remain  an  employee  of the
Company).

There are 24  participants  in the  special  incentive  plan,  including  eleven
executive officers. Approximately $2.9 million of special incentive bonuses were
awarded  under the plan.  A form of the special  incentive  bonus  agreement  is
attached.  The special  incentive bonus agreements for the three named executive
officers who  participated  in the special  incentive plan have been  separately
filed.

                                     Form of
                         MEMC Electronic Materials, Inc.
                        Special Incentive Bonus Agreement

     THIS  AGREEMENT is entered into between  MEMC  Electronic  Materials,  Inc.
("MEMC") and __________________ ("Employee").

     Employee is employed by MEMC.

     MEMC recognizes the value of the services  performed by Employee and wishes
to encourage  Employee to continue  employment with MEMC.  Employee wishes to be
paid a certain  amount of  additional  compensation  in  return  for  continuous
employment with MEMC for a designated period of time.

     NOW,  THEREFORE,  in consideration of the mutual promises contained in this
Agreement, the parties agree as follows:

     1. Nature of Contract. This Agreement provides for an additional bonus (the
"Special  Incentive  Bonus") to be paid by MEMC to Employee in consideration for
Employee's  continuous employment throughout the period of April 1, 1998 through
June 30, 1999 (the "Retention Period").

     Nothing  contained in this Agreement shall be construed to be a contract of
employment for any term,  nor as conferring  upon Employee the right to continue
in the  employment  of MEMC  in  Employee's  present  capacity  or in any  other
capacity.  Nothing  contained in this  Agreement  shall be construed to preclude
either party from terminating the employment relationship at any time.

     It is  expressly  understood  by the parties  that this  Agreement  relates
exclusively  to  additional  compensation  for  Employee's  services  and is not
intended to be the entire employment contract. This Agreement merely supplements
Employee's employment contract with MEMC.

     The Special  Incentive  Bonus  provided by this Agreement is in addition to
the cash compensation and other fringe benefits provided to Employee pursuant to
any plan or plans maintained by MEMC for its employees generally.

     2. Special  Incentive  Bonus. If Employee remains in the employment of MEMC
continuously  throughout the Retention  Period of April 1, 1998 through June 30,
1999,  Employee shall be entitled to a Special  Incentive Bonus in the amount of
_____________.

     3. Terms of Payment.  Fifty percent of the Special  Incentive Bonus will be
payable with the March 31, 1998 payroll (the "Advance  Payment");  the remaining
fifty percent of the Special  Incentive  Bonus will be payable with the June 30,
1999 payroll (the "Final Payment").

     Subject  to  the  exceptions  below,  in  the  event  Employee   terminates
employment  with MEMC before April 1, 1999,  Employee  shall  reimburse MEMC the
entire amount of the Advance Payment (including any payroll tax withheld).

     Subject  to  the  exceptions  below,  in  the  event  Employee   terminates
employment  with MEMC after  March 31,  1999 and before  July 1, 1999,  Employee
shall reimburse MEMC that portion of the Advance Payment  (including any payroll
tax  withheld)  that the number of days in the period  beginning  on the date of
Employee's termination of employment with MEMC and ending on June 30, 1999 bears
to 456.  For example,  if Employee  terminates  employment  with MEMC on June 1,
1999, Employee shall reimburse MEMC 30 / 456 (or 6.58%) of the Advance Payment.

     No  reimbursement  of the Advance Payment shall be required in the event of
the  death or total  and  permanent  disability  of  Employee,  or in the  event
Employee's employment with MEMC is involuntarily  terminated by MEMC as a result
of a change in control of MEMC or a  reduction  in the  workforce  of MEMC.  The
reimbursement  as described  above shall be required in the event of  Employee's
termination of employment with MEMC for any other reason.

     In no event shall Employee be entitled to the Final Payment in the event of
Employee's  termination  of  employment  with MEMC for any reason before July 1,
1999.

     4. Tax Withholding

     MEMC shall withhold from the Special  Incentive Bonus the amount  necessary
to enable MEMC to remit to the  appropriate  government  entity or entities  the
amount  required to be withheld  from wages with respect to such  payments.  All
references to the Special  Incentive Bonus,  the Advance Payment,  and the Final
Payment shall mean the gross amount of such amount before such payroll taxes are
withheld.

     5. Collection of Reimbursement

     Employee agrees that any  reimbursement  of the Advance Payment due MEMC in
the event of termination  of employment of the Employee  before July 1, 1999 may
be withheld by MEMC from any amounts owed by MEMC to Employee.

     6. Confidentiality

     Employee  agrees that the terms of this Special  Incentive  Bonus Agreement
are  confidential  and will not be discussed with or disclosed to any present or
former employee of MEMC or its affiliates or subsidiaries.

     7. Governing Law

     The  interpretation  and enforcement of this Agreement shall be governed by
the laws of the State of Missouri.

     Employee  acknowledges  that this  Agreement has been reviewed in detail by
Employee and that Employee voluntarily entered into this Agreement.

     IN WITNESS WHEREOF,  the parties have executed this Special Incentive Bonus
Agreement this ____ day of __________, 1998.

                         MEMC ELECTRONIC MATERIALS, INC.
                        SPECIAL INCENTIVE BONUS AGREEMENT

     THIS  AGREEMENT is entered into between  MEMC  Electronic  Materials,  Inc.
("MEMC") and Marcel Coinne ("Employee").

     Employee is employed by MEMC.

     MEMC recognizes the value of the services  performed by Employee and wishes
to encourage  Employee to continue  employment with MEMC.  Employee wishes to be
paid a certain  amount of  additional  compensation  in  return  for  continuous
employment with MEMC for a designated period of time.

     NOW,  THEREFORE,  in consideration of the mutual promises contained in this
Agreement, the parties agree as follows:

     1. Nature of Contract. This Agreement provides for an additional bonus (the
"Special  Incentive  Bonus") to be paid by MEMC to Employee in consideration for
Employee's  continuous employment throughout the period of April 1, 1998 through
June 30, 1999 (the "Retention Period").

     Nothing  contained in this Agreement shall be construed to be a contract of
employment for any term,  nor as conferring  upon Employee the right to continue
in the  employment  of MEMC  in  Employee's  present  capacity  or in any  other
capacity.  Nothing  contained in this  Agreement  shall be construed to preclude
either party from terminating the employment relationship at any time.

     It is  expressly  understood  by the parties  that this  Agreement  relates
exclusively  to  additional  compensation  for  Employee's  services  and is not
intended to be the entire employment contract. This Agreement merely supplements
Employee's employment contract with MEMC.

     The Special  Incentive  Bonus  provided by this Agreement is in addition to
the cash compensation and other fringe benefits provided to Employee pursuant to
any plan or plans maintained by MEMC for its employees generally.

     2. Special  Incentive  Bonus. If Employee remains in the employment of MEMC
continuously  throughout the Retention  Period of April 1, 1998 through June 30,

payable with the March 31, 1998 payroll (the "Advance  Payment");  the remaining
fifty percent of the Special  Incentive  Bonus will be payable with the June 30,
1999 payroll (the "Final Payment").

employment  with MEMC before April 1, 1999,  Employee  shall  reimburse MEMC the
entire amount of the Advance Payment (including any payroll tax withheld).

shall reimburse MEMC that portion of the Advance Payment  (including any payroll
tax  withheld)  that the number of days in the period  beginning  on the date of
Employee's termination of employment with MEMC and ending on June 30, 1999 bears
to 456.  For example,  if Employee  terminates  employment  with MEMC on June 1,
1999, Employee shall reimburse MEMC 30 / 456 (or 6.58%) of the Advance Payment.

     No  reimbursement  of the Advance Payment shall be required in the event of

the event of termination  of employment of the Employee  before July 1, 1999 may

                         MEMC ELECTRONIC MATERIALS, INC.
                        SPECIAL INCENTIVE BONUS AGREEMENT

     THIS  AGREEMENT is entered into between  MEMC  Electronic  Materials,  Inc.
("MEMC") and Ralph D. Hartung ("Employee").

     Employee is employed by MEMC.

     MEMC recognizes the value of the services  performed by Employee and wishes
to encourage  Employee to continue  employment with MEMC.  Employee wishes to be
paid a certain  amount of  additional  compensation  in  return  for  continuous
employment with MEMC for a designated period of time.

     NOW,  THEREFORE,  in consideration of the mutual promises contained in this
Agreement, the parties agree as follows:

     1. Nature of Contract. This Agreement provides for an additional bonus (the
"Special  Incentive  Bonus") to be paid by MEMC to Employee in consideration for
Employee's  continuous employment throughout the period of April 1, 1998 through
June 30, 1999 (the "Retention Period").

     Nothing  contained in this Agreement shall be construed to be a contract of
employment for any term,  nor as conferring  upon Employee the right to continue
in the  employment  of MEMC  in  Employee's  present  capacity  or in any  other
capacity.  Nothing  contained in this  Agreement  shall be construed to preclude
either party from terminating the employment relationship at any time.

     It is  expressly  understood  by the parties  that this  Agreement  relates
exclusively  to  additional  compensation  for  Employee's  services  and is not
intended to be the entire employment contract. This Agreement merely supplements
Employee's employment contract with MEMC.

     The Special  Incentive  Bonus  provided by this Agreement is in addition to
the cash compensation and other fringe benefits provided to Employee pursuant to
any plan or plans maintained by MEMC for its employees generally.

     2. Special  Incentive  Bonus. If Employee remains in the employment of MEMC
continuously  throughout the Retention  Period of April 1, 1998 through June 30,
1999,  Employee shall be entitled to a Special  Incentive Bonus in the amount of
$250,000.

     3. Terms of Payment.  Fifty percent of the Special  Incentive Bonus will be
payable with the March 31, 1998 payroll (the "Advance  Payment");  the remaining
fifty percent of the Special  Incentive  Bonus will be payable with the June 30,
1999 payroll (the "Final Payment").

     Subject  to  the  exceptions  below,  in  the  event  Employee   terminates
employment  with MEMC before April 1, 1999,  Employee  shall  reimburse MEMC the
entire amount of the Advance Payment (including any payroll tax withheld).

     Subject  to  the  exceptions  below,  in  the  event  Employee   terminates
employment  with MEMC after  March 31,  1999 and before  July 1, 1999,  Employee
shall reimburse MEMC that portion of the Advance Payment  (including any payroll
tax  withheld)  that the number of days in the period  beginning  on the date of
Employee's termination of employment with MEMC and ending on June 30, 1999 bears
to 456.  For example,  if Employee  terminates  employment  with MEMC on June 1,
1999, Employee shall reimburse MEMC 30 / 456 (or 6.58%) of the Advance Payment.

     No  reimbursement  of the Advance Payment shall be required in the event of
the  death or total  and  permanent  disability  of  Employee,  or in the  event
Employee's employment with MEMC is involuntarily  terminated by MEMC as a result
of a change in control of MEMC or a  reduction  in the  workforce  of MEMC.  The
reimbursement  as described  above shall be required in the event of  Employee's
termination of employment with MEMC for any other reason.

     In no event shall Employee be entitled to the Final Payment in the event of
Employee's  termination  of  employment  with MEMC for any reason before July 1,
1999.

     4. Tax Withholding

     MEMC shall withhold from the Special  Incentive Bonus the amount  necessary
to enable MEMC to remit to the  appropriate  government  entity or entities  the
amount  required to be withheld  from wages with respect to such  payments.  All
references to the Special  Incentive Bonus,  the Advance Payment,  and the Final
Payment shall mean the gross amount of such amount before such payroll taxes are
withheld.

     5. Collection of Reimbursement

     Employee agrees that any  reimbursement  of the Advance Payment due MEMC in
the event of termination  of employment of the Employee  before July 1, 1999 may
be withheld by MEMC from any amounts owed by MEMC to Employee.

     6. Confidentiality

     Employee  agrees that the terms of this Special  Incentive  Bonus Agreement
are  confidential  and will not be discussed with or disclosed to any present or
former employee of MEMC or its affiliates or subsidiaries.

     7. Governing Law

     The  interpretation  and enforcement of this Agreement shall be governed by
the laws of the State of Missouri.

     Employee  acknowledges  that this  Agreement has been reviewed in detail by
Employee and that Employee voluntarily entered into this Agreement.

     IN WITNESS WHEREOF,  the parties have executed this Special Incentive Bonus
Agreement this 24th day of March, 1998.

                              EMPLOYMENT AGREEMENT

         The  following  sets out Klaus R. von Horde's  agreement  regarding his
employment with MEMC Electronic Materials, Inc. ("MEMC")

1.   Employment  Term.  Mr. von Horde will be employed by MEMC as President  and
     Chief Operating Officer for the period  commencing  effective April 1, 1998
     and terminating March 31, 2003.

2.   Reporting  Responsibility.  Mr. von Horde will report directly to the Chief
     Executive Officer.  During the employment period, Mr. von Horde will devote
     his full  business  time to the  duties as  President  and Chief  Operating
     Officer of MEMC.

3.   Base  Salary.  Mr. von Horde's base salary will be  $416,000.00  per annum,
     which  may be  increased,  but  not  decreased,  at the  discretion  of the
     Compensation Committee of the Board of Directors of MEMC (the "Compensation
     Committee")  based upon performance and upon the  Compensation  Committee's
     review of the appropriate  base salary for the titles and  responsibilities
     assigned  to Mr. von Horde from time to time.  The  Compensation  Committee
     will review Mr. von Horde's base salary annually. Compensation of the Chief
     Operating  Officer is  primarily  a function  of  company  performance  and
     individual  performance  and could,  in any given year,  be higher or lower
     than that of other Chief Operating Officers in comparable positions. But it
     is the intent that MEMC's compensation  opportunity be structured to afford
     comparable pay given comparable performance.

4.   Annual  Bonus.  Mr. von Horde will be eligible  to receive an annual  bonus
     with a target at 140% of his  annual  base  salary as of  December  31. The
     target  bonus will be payable  to Mr.  von Horde only upon  achievement  of
     performance objectives set by the Compensation  Committee,  and the payment
     of any bonus above  target  will be at the  Compensation  Committee's  sole
     discretion.  The bonus will be paid under the Annual  Incentive  Plan under
     the same  performance  objectives and terms  applicable to other  executive
     employees.   Subsequent  target  levels  for  annual  bonuses,  performance
     objectives,  and payout terms will be at the discretion of the Compensation
     Committee.

5.   Stock Options.  In accordance with the MEMC Equity  Incentive Plan, Mr. von
     Horde will be awarded stock options  annually.  For the 1998 Plan year, Mr.
     von  Horde's  grant will be  comprised  of options to  purchase a number of
     shares  with a face value  equal to 365% of Mr. von  Horde's  salary (as of
     December 31 of the year prior to the  grant),  which  options  will have an
     exercise  price per share equal to 100% of market  value on the date of the
     grant.  The options will vest at the rate of 25% per year starting one year
     after the grant such that 100% vesting will occur on the fourth anniversary
     of the grant;  provided,  however,  that all options will vest upon Mr. von
     Horde's retirement on or following August 31, 2002, or earlier, if with the
     consent of the Compensation Committee.  The options shall in other respects
     be subject to the same terms  applicable to options granted to other senior
     executives.  Subsequent  grants,  the  value and  vesting,  shall be at the
     discretion of the  Compensation  Committee and shall follow the  guidelines
     set for other senior executives.

6.   Benefits.  Mr. von Horde will  participate  in the all  welfare  and fringe
     benefit  plans  maintained  by MEMC  for  its  senior  executive,  assuming
     insurability,  with  credit  given for Mr. von Horde's  prior MEMC  service
     solely for the purpose of eligibility to participate.

7.   Pension. Mr. von Horde will participate in the MEMC Pension Plan as well as
     the MEMC  Supplemental  Executive  Pension  Plan in  accordance  with their
     terms, based on an employment date with MEMC of April 1, 1998.

8.   Termination  of  Employment.  Either  party may  terminate  Mr. von Horde's
     employment  under this  Agreement  upon twelve (12) months'  prior  notice,
     delivered in writing. In the event of such a termination of employment; (a)
     Mr.  von  Horde  will  receive  all  salary  accrued  through  the  date of
     termination,  (b) MEMC will pay Mr. von Horde a pro rata bonus for the year
     of termination  (to be paid at the same time and to the same extent,  i.e.,
     based  on  MEMC's  performance  for the full  year  that  bonuses  are paid
     generally to executives with respect to such year),  (c) Mr. von Horde will
     be reimbursed for all  reasonable  relocation  expenses  incurred by him in
     returning to Germany with his family and (d) all stock  options  granted to
     Mr. von Horde will vest and remain  outstanding  and  exercisable for three
     (3) years following his termination date. Notwithstanding the foregoing, no
     advance  notice will be required  and items (b) through (d) above shall not
     apply in the event that Mr. von Horde is terminated for cause by MEMC or if
     he resigns.

9.   Arbitration.  Any dispute,  controversy or claim  regarding Mr. von Horde's
     employment  with MEMC or the termination of his employment will be resolved
     exclusively by final and binding arbitration. Such disputes,  controversies
     or claims would  include but not be limited to claims based upon  statutes,
     ordinances,  express  or  implied  contracts  or which  sound in tort.  The
     arbitrator  would have the authority to award  damages in  conformity  with
     controlling  substantive law. Such arbitration  would be held in St. Louis,
     Missouri,  U.S.A., in accordance with the rules of the American Arbitration
     Association.

10.  Confidentiality Agreement. MEMC's Confidentiality Agreement is incorporated
     by reference in this  Agreement and has been executed and  acknowledged  by
     Mr. von Horde.

11.  Miscellaneous.  This Agreement shall be construed in accordance with and be
     governed  by the laws of the  State of  Missouri  applicable  to  contracts
     executed  and to be performed  within such State.  It also  represents  the
     entire agreement of the parties regarding its subject matter and supersedes
     any prior or contemporaneous agreements or understandings,  whether written
     or oral.

Dr. Werner Schmitz

Chesterfield, MO 63005

Dear Dr. Schmitz:

     This  letter is to confirm  our mutual  understanding  with  respect to the
terms and conditions  under which you will provide  consulting  services to MEMC
Electronic Materials,  Inc. ("MEMC") for the period commencing July 1, 1998, and
ending  September  30, 1998,  inclusive,  which period may be extended by mutual
agreement.   Unless  the  context  clearly  indicates  otherwise,  all  of  your
obligations and duties under this agreement will be for the benefit of both MEMC
and any MEMC  Affiliate  for which you are rendering  services.  As used in this
letter agreement, the term "MEMC Affiliate" means any entity which is controlled
by, under common control with, or controls MEMC.

1.   The  services   ("Services")  which  you  will  provide  shall  consist  of
     consulting  with members of MEMC  management on issues  regarding the joint
     venture  agreements  and Board of Directors'  activities  for Taisil,  PHC,
     Kulim, and MCL and/or other business issues relating to Asia as requested.

     The MEMC Coordinator  shall be Ludger H. Viefhues or such other person whom
     MEMC designates in writing.

2.   It is understood  that the fee for your Services will consist of a lump-sum
     payment of $57,680  payable July 1, 1998  ("Lump-Sum  Fee").  MEMC shall be
     authorized to deduct from any sums  otherwise due you hereunder any amounts
     which by law MEMC may be  required to  withhold  from such sums;  provided,
     however,  that MEMC does not  assume  nor shall be deemed to assume  hereby
     (unless instructed or ordered by appropriate governmental authority) any of
     your  responsibilities  as a  self-employed  individual to pay any federal,
     state or local income or earnings taxes or  self-employment  taxes,  all of
     which shall remain your sole obligation.

     In  addition,  an MEMC  laptop  computer  shall be  provided to you for the
     duration of this agreement.

3.   MEMC will reimburse you for reasonable and necessary  expenses you incur in
     connection with your Services, including: (a) business travel expenses when
     travel is required and pre-approved by the MEMC  Coordinator;  (b) costs of
     room and board for you while you are located  more than 100 miles from your
     home; and (c) special items agreed to by the MEMC Coordinator in advance of
     being incurred.

4.   You will submit monthly a detailed  invoice for Services  rendered  setting
     forth the days worked and services performed and itemizing any reimbursable
     expenses. Your invoices shall be submitted to the MEMC Coordinator.  To the
     extent  approved  by the MEMC  Coordinator,  payment  shall be made by MEMC
     within  ten (10)  days  after the  receipt  of your  invoice.  Unless it is
     otherwise  agreed in writing by the  parties,  payments to you will be made
     solely in U.S. Dollars,  sent to the address specified in your invoice,  or
     deposited in a United States bank account specified by you.

5.   This agreement  shall  automatically  terminate in the event of your death,
     your incapacity or inability (as determined by MEMC) to perform your duties
     hereunder  or if you refuse to accept an  assignment  offered to you.  MEMC
     terminate this agreement upon thirty (30) days written notice. In addition,
     MEMC may terminate  this  agreement on written  notice if you breach any of
     the provisions of this  agreement.  In the event of the termination of this
     agreement  for any reason,  MEMC shall only be liable for the  Lump-Sum Fee
     and reimbursable expenses incurred prior to the effective termination date.

6.   In providing the Services, you shall disclose to MEMC only such information
     as you are legally  free to  disclose.  MEMC shall have the right,  without
     further payment over and above that set forth in Paragraph 2 above, forever
     to use  freely  any  and  all  information  disclosed  by you to  MEMC.  In
     addition,  you shall  not  disclose  or  divulge  to MEMC any  proprietary,
     confidential or trade secret information of third parties.

7.   It is recognized  that, in providing  the Services to MEMC  hereunder,  you
     will or may acquire or develop  certain  confidential  information and data
     ("Information") concerning the plans, profits, programs, plants, processes,
     products,  costs,  equipment,  operations,   customers,  raw  materials  or
     suppliers  of, or  belonging  to,  MEMC.  Therefore,  you  shall  treat the
     Information as MEMC's  confidential  property and shall not, except for the
     limited  purpose of  providing  Services  hereunder,  use or disclose  such
     Information to third parties,  without in each instance  securing the prior
     written consent of MEMC. All notes, memoranda,  records, tapes, print-outs,
     and other documents (including,  but not limited to, all drafts, copies and
     excerpts  thereof)  embodying or referring to the Information  shall be the
     property  of MEMC and shall be  delivered  to MEMC upon the  completion  or
     termination  of  Services  hereunder  or  at  MEMC's  request.   The  above
     obligations shall survive completion or termination of Services hereunder.

8.   Nothing  contained  herein  shall  prevent  you from  using  or  disclosing
     Information  which you can prove (a) has become  part of the public  domain
     other than by your acts or omissions,  (b) has been furnished or made known
     to you by third  parties  (other than those  acting on behalf of MEMC) as a
     matter of legal right and without  restriction on disclosure or use, or (c)
     was in your possession  prior to disclosure by MEMC and was not acquired by
     you directly or indirectly  from MEMC. It is further  understood and agreed
     that specific Information shall not be deemed to be available to the public
     or in your prior  possession  merely because it is embraced by more general
     information  available to the public or in your prior possession,  and that
     the existence of MEMC's  particular  interests and plans in the  electronic
     materials business are recognized as a type of such specific information.

9.   It is  agreed  that the  entire  right,  title and  interest  in and to all
     copyrightable works, including all copyright interests therein,  created or
     authored by you (a) during the period of time you are providing services to
     MEMC or within one year of the completion or termination  thereof and which
     are  directly  related to any  assignment  or project with respect to which

ACCEPTED AND AGREED TO AS OF
THE DATE FIRST ABOVE WRITTEN:


/s/ Werner Schmitz
- ----------------------------
Dr. Werner Schmitz

          SEPARATION AGREEMENT, GENERAL RELEASE AND COVENANT NOT TO SUE

     This  Separation  Agreement,  General  Release  and  Covenant  Not  to  Sue
("Agreement")  is  made  and  entered  into  by and  between  Ralph  D.  Hartung
(hereafter  "EMPLOYEE") and MEMC Electronic Materials,  Inc. (hereafter "MEMC").
In consideration of the following promises, the parties agree as follows:

     1. Separation from Employment.  EMPLOYEE acknowledges that he will separate
from employment with MEMC effective as of August 1, 1998 (hereafter  "Separation
Date"),  which will be his last  effective  day of work.  As of such  Separation
Date, EMPLOYEE's  employment  relationship with MEMC will end. MEMC and EMPLOYEE
have agreed to settle all matters relating to EMPLOYEE's employment relationship
with MEMC and the termination.

     2. Resignation of EMPLOYEE.  EMPLOYEE tenders his resignation  effective as
of the Separation Date, which resignation is hereby accepted by MEMC. EMPLOYEE's
MEMC personnel file will reflect a voluntary resignation.

     3. Payments and  Benefits.  MEMC shall provide the following to EMPLOYEE in
consideration and in exchange for EMPLOYEE's  promises and obligations herein so
long as he submits this Agreement,  properly executed, to MEMC on or before June
11, 1998 and adheres to the promises and agreements  set out in this  Agreement.
The payments  and  benefits  are made in lieu of any  payments or benefits  that
might  otherwise  be available to EMPLOYEE  arising out of his  employment  with
MEMC.

          a.   Separation  Payments and Benefits.  EMPLOYEE shall be entitled to
               the  separation  payments  and  benefits  set forth on  Exhibit A
               hereto  as  though   EMPLOYEE  were  part  of  MEMC's   Voluntary
               Separation Plan (including the Furloughed Early Retirement Plan).
               In addition, if prior to December 31, 1998, the MEMC Compensation
               Committee  removes  the 6%  limitation  on the  amount  of annual
               increases in base salary that may be taken into consideration for
               purposes of determining  final average pay under the MEMC Pension
               Plan and the MEMC  Supplemental  Executive Pension Plan, then the
               pension  benefits  payable to  EMPLOYEE  under such plans will be
               determined  (on a retroactive  basis)  without  regard to such 6%
               limitation.

          b.   Retention of Special  Incentive Bonus.  Effective as of March 24,
               1998,  EMPLOYEE entered into a Special  Incentive Bonus Agreement
               pursuant  to  which   EMPLOYEE   was  paid  a  sum  of  money  in
               consideration for his agreement to continue  employment with MEMC
               through June 30, 1999.  Pursuant to said Special  Incentive Bonus
               Agreement, EMPLOYEE is required to reimburse MEMC for the Advance
               Payment as defined in said agreement in the amount of $125,000 as
               a result of the  termination of his employment with MEMC prior to
               June 30, 1999.  However,  MEMC hereby waives said requirement and
               EMPLOYEE shall be permitted to retain said Advance Payment in the
               amount of $125,000.  Notwithstanding  the foregoing,  the Advance
               Payment  shall not be  considered  for  purposes  of  determining
               EMPLOYEE'S  final average pay under the MEMC Pension Plan and the
               MEMC Supplemental Executive Pension Plan.

          c.   International  Assignment Letter of Agreement.  MEMC and EMPLOYEE
               agree to  comply  with  the  terms  of  EMPLOYEE's  International
               Assignment  Letter of Agreement  dated April 1, 1993, as modified
               by the  memorandum to EMPLOYEE from Larry Norman dated January 8,
               1998 addressing EMPLOYEE's  repatriation from Italy to the United
               States   (as   so   modified,   the   "International   Assignment
               Agreement").   In  connection   with   EMPLOYEE's   international
               assignment, EMPLOYEE and MEMC agree to comply with the tax return
               preparation   provisions  (which   provisions   provide  for  the
               preparation  of  EMPLOYEE's  tax returns at MEMC's  expense for a
               specified  period  of time) of  MEMC's  International  Assignment
               Policy (including the provisions addressing foreign tax credits).

     4. Agreement Not to File Suit. In consideration of the promises of MEMC set
forth  in  this  Agreement,  EMPLOYEE  agrees  for  himself  and on  behalf,  as
applicable, his heirs,  beneficiaries,  executors,  administrators,  successors,
assigns, and anyone claiming through or under any of the foregoing, that he will
not file or  otherwise  submit any  charge,  claim,  complaint  or action to any
agency, court,  organization,  or judicial forum (nor will he permit any person,
group of persons,  or  organization  to take such action on his behalf)  against
MEMC,  nor file  any  such  charge,  claim,  complaint  or  action  against  any
subsidiary,  affiliate  or  parent  company  of  MEMC,  or any  officer,  agent,
employee,  successor or assign of any of MEMC or any of said  entities,  arising
out of any actions or  non-action on the part of MEMC or on the part of any such
entity  or any  officer,  agent  or  employee  of MEMC or any such  entity  that
occurred on or prior to the date of  execution of this  Agreement.  Said claims,
complaints  and  actions  include,  but are not limited to, (i) any breach of an
actual or implied  contract of employment  between  EMPLOYEE and MEMC,  (ii) any
claim of unjust,  wrongful, or tortious discharge (including any claim of fraud,
negligence,  whistle blowing, or intentional  infliction of emotional distress),
(iii) any claim of defamation or other common-law  action,  or (iv) any claim of
violations  arising  under the Civil Rights Act of 1964,  as amended,  42 U.S.C.
Section  2000e et seq.,  42  U.S.C.  Section  1981,  the Age  Discrimination  in
Employment  Act, 29 U.S.C.  Section 621 et seq., the American with  Disabilities
Act, 42 U.S.C.  Section 12101 et seq., the Fair Labor  Standards Act of 1938, as
amended,  29 U.S.C.  Section 201 et seq.,  the  Rehabilitation  Act of 1973,  as
amended, 29 U.S.C.  Section 701 et seq., the Employee Retirement Income Security
Act ("ERISA"),  29 U.S.C.  Section 1001 et seq., or any other relevant  federal,
state, or local statute or ordinance.

     5. Release of Claims. EMPLOYEE hereby agrees for himself, and as applicable
his heirs, beneficiaries,  executors,  administrators,  successors,  assigns and
anyone claiming  through or under any of the foregoing,  to remise,  release and
forever discharge MEMC and the subsidiaries, affiliates, and parent companies of
MEMC, and all officers, agents, employees,  successors and assigns of MEMC or of
said entities,  from any and all matters,  claims,  demands,  damages, causes of
action, debts, liabilities, controversies, judgments and suits of every kind and
nature whatsoever,  foreseen,  unforeseen,  known or unknown,  including claims,
complaints  and actions  described  in  Paragraph  4, which have arisen or could
arise between EMPLOYEE,  on the one hand, and MEMC or said related entities,  on
the other hand, from matters which occurred on or prior to the date of execution
of  this  Agreement,   which  matters  include  this  Agreement  and  EMPLOYEE's
separation of employment with MEMC.

     6. Release and Waiver of Other Claims. Except as expressly provided in this
Agreement,  EMPLOYEE agrees, for himself, and, as applicable, for and on behalf,
of his heirs, beneficiaries, executors, administrators, successors, assigns, and
anyone  claiming  through or under any of the foregoing,  to further release and
waive any claims related to pay, vacation pay,  insurance or welfare benefits or
any other benefits of employment  with MEMC arising from events  occurring on or
prior to the date of execution of this Agreement.  Notwithstanding any provision
of this  Agreement,  this  Agreement  does not  include any release or waiver of
EMPLOYEE's non-forfeitable rights to his accrued benefits (within the meaning of
Sections  203 and 204 of  ERISA),  if any,  under the MEMC  Pension  Plan,  MEMC
Supplemental  Executive  Pension Plan and the MEMC  Retirement  Savings Plan, as
such plans may  hereafter be amended,  which rights are not released  hereby but
survive  unaffected by this  Agreement.  In addition,  this  Agreement  does not
include any release or waiver of EMPLOYEE'S rights existing as of the Separation
Date under the MEMC Electronics Materials, Inc. Welfare Benefit Plan.

     7. Obligation Regarding Confidential  Information.  EMPLOYEE agrees that he
has continuing  obligations to MEMC pursuant to his Employment Agreement between
him and MEMC  dated  March 17,  1989.  Any  violation  of those  obligations  by
EMPLOYEE  constitutes  a material  breach of this  Agreement  and  subjects  the
EMPLOYEE to forfeiture of all benefits and payments  pursuant to this Agreement.
MEMC expressly  reserves the right to pursue all other legal remedies  available
to it by virtue of any breach of the Employment Agreement.

     8.  Nondisparagement.  EMPLOYEE  represents  that he will not,  in any way,
disparage MEMC nor any subsidiary,  affiliate or parent of MEMC, or any officer,
agent,  employee,  successor  or assign of any of them,  or make or solicit  any
comments,  statements  or the  like  to  the  media  or to  others  that  may be
considered  to be  derogatory  or  detrimental  to the  good  name  or  business
reputation of any of the  aforementioned  persons or entities.  MEMC  represents
that it will  not,  in any  way,  disparage  EMPLOYEE,  or make or  solicit  any
comments,  statements  or the  like  to  the  media  or to  others  that  may be
considered  to be  derogatory  or  detrimental  to the  good  name  or  business
reputation of EMPLOYEE.

     9. No  Admission  of  Wrongdoing.  The parties  agrees that nothing in this
Agreement is an admission by any party of any wrongdoing, either in violation of
an  applicable  law or  otherwise,  and that nothing in this  Agreement is to be
construed as such by any person.

     10. Confidentiality of Agreement. EMPLOYEE agrees to keep the terms of this
Agreement  confidential  except  as he  might  be  lawfully  compelled  to  give
testimony by a court of competent  jurisdiction or as he may be required by law,
regulation,  governmental authority or similar body to disclose. This means that
except as stated  above,  he will not, at any time,  talk about,  write about or
otherwise   publicize  this  Agreement,   or  its   negotiation,   execution  or
implementation,  except  with  (1)  an  attorney  who  may  be  advising  him in
connection  with  it;  (2) a  financial  consultant  or  executive  outplacement
counselor,  and (3) his wife  provided  that said persons to whom  disclosure is
permitted  pursuant to this sentence promise to keep the information that may be
revealed to them confidential and not to disclose it to others.

     11. Knowing and Voluntary Agreement.  EMPLOYEE hereto represents,  declares
and agrees that he voluntarily  accepts the provisions of this Agreement for the
purposes of making a full and final compromise, adjustment and settlement of all
claims herein  described.  EMPLOYEE is advised to consult an attorney.  EMPLOYEE
understands the effect of signing this Agreement.

     12. Entire Agreement.  This Agreement,  when executed,  contains the entire
agreement  between  the  parties  and  there  are  no  other  understandings  or
agreements,  written or oral,  between  them on the subject  except as expressly
stated herein.  This Agreement  fully  supersedes and replaces any and all prior
agreements or  understandings,  if any,  between EMPLOYEE and MEMC on any matter
that is  addressed  in this  Agreement.  This  Agreement  cannot be  amended  or
modified except by a written document signed by both MEMC and EMPLOYEE. Separate
copies of this document shall constitute  original documents which may be signed
separately, but which together will constitute one single agreement.

     13.  Governing  Law;  Invalidity of  Provisions.  This  Agreement  shall be
construed and governed by the laws of the State of Missouri (except its laws and
decisions  regarding  conflicts  of law  which  shall  be  disregarded  in their
entirety).  If any part or  provision  of this  Agreement  is  determined  to be
invalid or unenforceable under applicable law, the validity or enforceability of
the remaining  provisions shall be unaffected.  To the extent that any provision
of this Agreement is adjudicated  to be invalid or  unenforceable  because it is
over broad,  that provision  shall not be void, but rather shall be limited only
to the extent required by applicable law and enforced as so limited.

     14.  Consequences of Violation of this Agreement.  If EMPLOYEE violates any
of his promises  contained in this  Agreement,  then EMPLOYEE  shall pay for all
costs incurred by any of the released parties,  including reasonable  attorneys'
fees, in defending against EMPLOYEE's claims. For example, if any released party
is required to defend a lawsuit  filed by EMPLOYEE or on his behalf that relates
to EMPLOYEE'S employment or the termination of his employment, EMPLOYEE shall be
liable  for all  expenses  (including  attorneys'  fees)  that are  incurred  in
defending  this suit.  If MEMC  violates any of its  promises  contained in this
Agreement,  then MEMC shall pay for all costs  incurred by  EMPLOYEE,  including
reasonable attorneys' fees, in enforcing EMPLOYEE's rights under this Agreement.

     15. Consideration  Period.  EMPLOYEE acknowledges that he has been given at
least  twenty-one  (21) days within which to consider this Agreement  before its
execution.  This Agreement  shall not be effective until seven (7) calendar days
after the date of execution by EMPLOYEE.  During this seven-day period, EMPLOYEE
may revoke this Agreement by notifying MEMC in writing.  Upon  expiration of the
seven-day  period,  EMPLOYEE  acknowledges that this Agreement becomes final and
binding.

     16. By signing this Agreement, EMPLOYEE acknowledges:

          A.   HE HAS READ THIS AGREEMENT COMPLETELY.

          B.   HE  HAS  HAD  AN  OPPORTUNITY  TO  CONSIDER  THE  TERMS  OF  THIS
               AGREEMENT.

          C.   HE HAS BEEN  ADVISED TO CONSULT  WITH AN ATTORNEY OF HIS CHOOSING
               PRIOR TO EXECUTING THIS AGREEMENT.

          D.   HE KNOWS THAT HE IS GIVING UP  IMPORTANT  LEGAL RIGHTS BY SIGNING
               THIS AGREEMENT.

          E.   HE  UNDERSTANDS  AND  MEANS  EVERYTHING  THAT HE HAS SAID IN THIS
               AGREEMENT, AND HE AGREES TO ALL ITS TERMS.

          F.   HE IS NOT  RELYING  ON  MEMC  OR ANY  REPRESENTATIVE  OF  MEMC TO
               EXPLAIN THIS AGREEMENT OR HIS RIGHTS TO HIM

          G.   HE HAS HAD AN  OPPORTUNITY  TO  CONSULT  AN  ATTORNEY  AND  OTHER
               ADVISORS TO EXPLAIN THIS  AGREEMENT AND ITS  CONSEQUENCES  TO HIM
               BEFORE  HE  SIGNED  IT,  AND  HE  HAS  AVAILED  HIMSELF  OF  THIS
               OPPORTUNITY TO WHATEVER EXTENT HE DESIRED.

          H.   HE HAS SIGNED THIS AGREEMENT  VOLUNTARILY AND ENTIRELY OF HIS OWN
               FREE WILL WITHOUT ANY PRESSURE FROM MEMC OR ANY REPRESENTATIVE OF
               MEMC.

to exceed  $50,000,000.00  and HC is willing,  subject to and upon the terms and
conditions herein set forth, to make such a loan to MEMC.

NOW THEREFORE IT IS AGREED:

1.   Principal and Value:  From time to time,  beginning  July 1, 1998, HC shall
     lend to MEMC and MEMC shall  borrow from HC an amount to be  designated  by
     MEMC,  not to exceed  $50,000,000.00  outstanding at any one time. The loan
     shall  be  evidenced  by a  promissory  note in  substantially  the form of
     Exhibit "A" attached hereto. All loans and repayments shall be made by MEMC
     by  drawing  funds in  multiples  of  $5,000,000  from an MEMC  account  at
     Citibank  N.A.,  New York,  New York that  will  zero  balance  with the HC
     account   at   Citibank   N.A.,   New   York  ,  New  York   (Account   No.
     4070-0001)("designated  account").  MEMC shall notify HC of borrowing[s] by
     10 am Central time on the third  business day prior to the day the money is
     to be borrowed.

2.   Term and Maturity:  The principal amount of the loan  outstanding  together
     with  any  interest  due  and  outstanding  shall  be paid by MEMC to HC on
     September  30,  1998,  or at such later date as may be  mutually  agreed in
     writing by the  parties.  MEMC shall not be  entitled  to repay the loan[s]
     before maturity without the prior written consent of HC.

3.   Interest Rates: Interest shall be calculated daily at 7.22%, beginning with
     the date of  borrowing  and shall be  calculated  based upon a 365/360  day
     year.

4.   Payment of Interest:  Payments of interest  shall be made by wire transfer,
     or other method of same day  settlement,  only on banking  days,  not later
     than 10:00 a.m. Central time, to the account of HC, with Citibank N.A., New
     York, New York,  (Account No.  4070-0001) or to such other account of HC as
     it may designate. Interest will be payable monthly, on the last banking day
     of each month.

5.   PENALTIES:  If MEMC shall borrow an amount different than which it notifies
     HC pursuant to paragraph 1, MEMC shall pay to HC a penalty equal to the .5%
     of the amount of the  understatement  divided by 360. If MEMC shall draw an
     amount in excess of $50,000,000,  MEMC shall pay HC a penalty equal to 3.0%
     of the excess amount  multiplied by the number of days outstanding  divided
     by 360.  All  penalties  shall  be in  addition  to  interest  computed  in
     accordance with other provisions of this agreement.

6.   Liens,  etc. On and after the date of this Loan Agreement  until  September
     30, 1998 or such later date as any loan hereunder shall remain unpaid, MEMC
     will not, unless HC shall otherwise consent in writing, create or suffer to
     exist, any lien,  security interest or other charge or encumbrance,  or any
     other type of preferential arrangement,  upon or with respect to any of its
     properties, whether now owned or hereafter acquired, or assign any right to
     receive  income,  in each  case to secure  any debt  owed to any  person or
     entity, other than:

          (a) purchase money liens or purchase money security  interests upon or
          in any  property  acquired or held by MEMC in the  ordinary  course of
          business to secure the  purchase  price of such  property or to secure
          indebtedness   incurred  solely  for  the  purpose  of  financing  the
          acquisition of such property;

          (b) liens or security  interests existing on such property at the time

          the extent not yet due or to the extent  such  taxes,  assessments  or
          government  charges or levies are being contested in good faith and by
          proper  proceedings  and as to which  appropriate  reserves  are being
          maintained,  unless and until any lien resulting therefrom attaches to
          MEMC's property and becomes enforceable against its other creditors;

          (d)  liens  imposed  by  law,  such  as   materialmen's,   mechanics',
          carriers',  workmens'  and  repairmen's  liens and other similar liens
          arising in the ordinary course of business  securing  obligations that

          (e)  pledges  or  deposits  to  secure   obligations   under  workers'
          compensation  laws or  similar  legislation  or to  secure  public  or
          statutory obligations;

          (f) easements,  rights of way and other  encumbrances on title to real
          property that do not render title to the property  encumbered  thereby
          unmarketable or materially  adversely  affect the use of such property
          for its present purposes; and

          (g) liens incurred or deposits made in the ordinary course of business
          to secure the performance of letters of credit,  bids, tenders,  sales

          similar  obligations  not incurred in connection with the borrowing of
          money.
