Item 4.  Purpose of Transaction.

         Pursuant to the Purchase  Agreement,  dated as of October 22, 1998 (the
"Purchase   Agreement"),   between  VEBA  Corporation  and  the  Company,   VEBA
Corporation agreed,  subject to the satisfaction or waiver of various conditions
set forth in the Purchase Agreement,  to purchase for a per share purchase price
equal to the volume  weighted  average  trading  price of the Common Stock for a
specified  five day  consecutive  trading  day period  (the "Per Share  Purchase
Price") a number of shares of Common Stock  approximately  equal to  106,100,000
divided  by the Per Share  Purchase  Price.  The  purpose of  entering  into the
Purchase  Agreement is to assist the Company in meeting certain  financial needs
arising before completion of the Rights Offering (described below).

         On October 22, 1998, the Company filed with the Securities and Exchange
Commission a  Registration  Statement on Form S-3 (the "Form S-3") relating to a
distribution on a pro rata basis to all  stockholders of the Company (other than
VEBA  Corporation)  of rights which entitle the holders  thereof to purchase one
share of Common  Stock  for each  right as well as  additional  shares of Common
Stock to the extent that other rights  holders do not exercise their rights (the
"Rights Offering").  In the Rights Offering, the Company will issue for the same
Per Share  Purchase  Price to be paid

- -------------------------------------------------------------------------------


by VEBA  Corporation  under the Purchase  Agreement a number of shares of Common
Stock approximately equal to 93,900,000 divided by the Per Share Purchase Price.
The purpose of the Rights  Offering is to allow all  stockholders of the Company
(other than VEBA  Corporation)  to restore their  proportionate  interest in the
Company at the same price per share previously offered to VEBA Corporation under
the Purchase Agreement.

         In  connection  with the  Rights  Offering,  VEBA  Corporation  and the
Company  entered into the Standby  Agreement,  dated as of October 22, 1998 (the
"Standby Agreement"),  pursuant to which VEBA Corporation has agreed, subject to
the  satisfaction  or  waiver of  various  conditions  set forth in the  Standby
Agreement,  to purchase all shares of Common Stock not otherwise  subscribed for
by other  stockholders in the Rights Offering.  The purpose of entering into the
Standby  Agreement  is to assist the Company in raising an  aggregate  amount of
approximately  $93,900,000,  to the extent that rights are not  exercised in the
Rights Offering.

         In  connection  with the  execution of the Purchase  Agreement  and the
Standby  Agreement,  VEBA  Corporation  and the Company  intend to enter into an
amendment (the  "Amendment") to the  Registration  Rights  Agreement dated as of
July 12, 1995 between Huls Corporation and the Company

(the  "Registration  Rights  Agreement").  The  purpose  of  entering  into  the
Amendment  is to reflect the change of record  ownership of the shares of common
stock of the  Company  reported  herein  (the "MEMC  Shares") as a result of the
merger  described  in Item  5(a)  below  and to  include  in the  definition  of
"Registrable  Stock"  in the  Registration  Rights  Agreement,  and  extend  the
benefits of the Registration Rights Agreement to, (i) all shares of Common Stock
to be acquired by VEBA Corporation as a result of the transactions  contemplated
by the  Purchase  Agreement  and the  Standby  Agreement  and (ii) any shares of
Common Stock  acquired by VEBA  Corporation  or VEBA AG and any of its direct or
indirect  subsidiaries  after the date of the Purchase Agreement and the Standby
Agreement.

         Pursuant to the Registration Rights Agreement, VEBA Corporation has the
right to demand  registration under the Securities Act of 1933 (as amended,  the
"Securities  Act") of any or all of the  Registrable  Stock (as  defined  in the
Registration Rights Agreement). The demand rights must be exercised for at least
25% of the Registrable  Stock. The Company may be required to effect up to three
such demand  registrations.  VEBA Corporation will bear the expenses of any such
demand registration. The Company is not obligated to take any action to register
the  Registrable  Stock:  (i) during the  period  starting  30 days prior to the
estimated date of filing of, and ending 90 days after the

effective date of, any other  registration  statement filed by the Company under
the Securities Act; (ii) more than once during any six-month  period;  and (iii)
for up to 90 days after a request from VEBA  Corporation if one of the Company's
officers  certifies that the Company's  Board of Directors has  determined  that
such registration would interfere with a material transaction then being pursued
by the Company.  In  addition,  except in certain  circumstances  and subject to
certain  limitations,  if the Company  proposes to register any shares of Common
Stock under the Securities Act, VEBA Corporation will be entitled to require the
Company  to  include  all  or  a  portion  of  the  Registrable  Stock  in  such
registration.  The  expenses of any such  "piggyback"  registration,  other than
underwriting  discounts and commissions  relating to the Registrable Stock to be
sold by VEBA Corporation, shall be borne by the Company.

         In connection  with any  registration  statement  filed pursuant to the
Registration  Rights  Agreement,  the  Company  has  agreed  to  indemnify  VEBA
Corporation  and its  transferees  and  assignees  and any  underwriter  against
certain liabilities, including liabilities under the Securities Act.

         The preceding summary of certain provisions of the Purchase  Agreement,
the Standby  Agreement and the Registration  Rights Agreement is not intended to
be complete  and is  qualified  in its entirety by reference to the full

text of such  agreements,  copies  of which are filed as  Exhibits  2-4  hereto,
respectively, and which are incorporated herein by reference.

         VEBA AG has indirectly owned the MEMC Shares continuously for more than
nine years and has not  decreased  its equity  investment  in the Company.  VEBA
Corporation  currently  owns the MEMC Shares and will own  additional  shares of
Common  Stock as a  result  of the  transactions  contemplated  by the  Purchase
Agreement and the Standby Agreement and upon exercise of any rights purchased by
VEBA Corporation on the New York Stock Exchange during the Rights Offering. VEBA
Corporation is owned by VEBA AG  (approximately  50.1%),  Huls AG (approximately

Item 5.  Interest in the Securities of the Issuer.

         (a) VEBA  Corporation  is the record owner of 21,490,942  shares of the
Common Stock as a result of the merger of Huls Corporation, the former owner and
wholly-owned  subsidiary of VEBA Corporation,  with and into VEBA Corporation on
September  30, 1998.  Such shares  constitute  approximately  53.1% of the total
number of outstanding  shares of the Common Stock (based on the number of shares
of Common Stock  reported as outstanding in the Form S-3) and do not include the
shares of Common  Stock to be acquired  pursuant to the Purchase  Agreement  and
possibly the Standby Agreement described in Item 4 above.

         Except as set forth below,  no executive  officer or director of any of
the Reporting Persons is the beneficial owner of any shares of the Common Stock:

         Dr. Erhard  Meyer-Galow,  Member of the Board of Management of VEBA AG,
Chairman of the Board of Stinnes AG and a director of the Company,  is the owner
of 12,000  shares of Common  Stock and has the right to  acquire  700  shares of

his wife,  of 2,500  shares of Common  Stock.  Neither Dr.  Meyer-Galow  nor Mr.
Stuehmeier  beneficially  owns  one  percent  or more  of the  total  number  of
outstanding  shares of the Common  Stock  (based on the number of shares  Common
Stock reported outstanding in the Form S-3).

         (b)  VEBA  AG,  acting  through  its  wholly-owned  subsidiaries,  VEBA
Corporation,  Stinnes  AG,  and Huls AG,  indirectly  has sole  power to vote or
direct the vote,  and to dispose or to direct the  disposition  of the shares of
the  Common  Stock  beneficially  owned by VEBA AG. As a result,  VEBA AG may be
deemed to  beneficially  own the shares of the Common  Stock  owned of record by
VEBA Corporation.

         Dr.  Meyer-Galow  has sole  power to vote or direct  the  vote,  and to
dispose  or  direct  the  disposition  of 12,700  shares of Common  Stock of the
Company.

dispose or direct the disposition of 2,500 shares of Common Stock of the Company
which he owns jointly with his wife.

         (c) Except as  described  in Item 4 above and the merger  described  in
Item 5(a)  above,  there  have not been any  transactions  in the  Common  Stock
effected by or for the account of any of the Reporting  Persons or any executive

         (d)  Except  as stated  in this  Item 5, to the best  knowledge  of the
Reporting  Persons,  no other  person  has the right to  receive or the power to
direct the receipt of  dividends  from,  or the  proceeds  from the sale of, the
shares of Common Stock owned by the Reporting Persons.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

         See Item 4 above  for a  description  of the  Purchase  Agreement,  the
Standby  Agreement and the Registration  Rights  Agreement,  copies of which are
filed as Exhibits 2-4 hereto, respectively, and which are incorporated herein by

         The Company and VEBA AG and its affiliates  have amended,  effective as
of September 1, 1998,  their existing  credit  agreements  (the "Amended  Credit
Agreements")  to, among other things,  extend the maturity  dates of outstanding
loans to the Company that mature prior to January 1, 2001 until their respective
maturity date  anniversaries in 2001, and increase the interest rates payable by
the Company on all of the Company's existing debt to VEBA AG and its affiliates.
The increased  interest  rates reflect the longer

maturities  and are priced at interest  rate  spreads  applicable  to an average
industrial  borrower at a specified credit rating. The interest rates payable on
the loans that are extended until 2001 will be adjusted at the time of extension
to reflect the  then-current  interest  rate  spreads  applicable  to an average
industrial borrower at a specified credit rating.

         The  Amended  Credit  Agreements  provide  that  if  VEBA  AG  and  its
affiliates own less than a majority of the outstanding Common Stock on and after
January 1, 2001,  then the  interest  rates  payable by the Company  will be the
higher of (a) the interest rate  currently set forth in each such loan agreement
or (b) an  interest  rate  determined  as of the change of  control  date for an
average industrial  borrower at a specified credit rating based on the remaining
term of each such loan  agreement.  In addition,  in such event the Company will
become subject to certain affirmative  covenants set forth in the Amended Credit
Agreements.

         The annual commitment fee payable by the Company on the undrawn portion
of loans  pursuant  to the  Amended  Credit  Agreements  is 1/4 of one  percent.
Additionally,  the Amended  Credit  Agreements  require the Company,  subject to
certain  exceptions  in the ordinary  course of the Company's  business,  to not
allow any encumbrances,  such as mortgages and security interests,  to be placed
on its assets.

Company on a revolving  basis at interest rate spreads  applicable to an average
industrial  borrower  at a  specified  credit  rating.  The  other  terms of the
Revolving   Credit  Agreement  are  similar  to  those  of  the  Amended  Credit
Agreements.

                               PURCHASE AGREEMENT


         THIS PURCHASE AGREEMENT (the "Agreement") is entered into as of October
22, 1998, by and among VEBA Corporation,  a Delaware corporation  ("VEBA"),  and
MEMC Electronic Materials, Inc., a Delaware corporation (the "Company").

                                    RECITALS


         A. The Company proposes to issue (the "Rights  Offering") to holders of
its Common  stock,  par value $0.01 per share (the "Common  Stock"),  other than
VEBA,  upon the terms and subject to the  conditions set forth in the prospectus
(the "Prospectus")  contained in the Registration Statement (as herein defined),
rights (the "Rights") to purchase  shares of its Common Stock,  exercisable at a
price per share equal to the Purchase Price (as hereinafter defined). The Rights
and the Common Stock issuable upon exercise  thereof are  hereinafter  sometimes
collectively referred to as the "Rights Securities;" and

         B. The Company proposes to issue and sell to VEBA, and VEBA proposes to
buy from the  Company,  upon the terms and subject to the  conditions  set forth
herein,  the Common Shares (as herein defined) at a price per share equal to the
Purchase Price,  which will be identical to the subscription price in the Rights
Offering.

         NOW,  THEREFORE,  in  consideration  of the  recitals  and  the  mutual
covenants,  representations,  warranties,  conditions and agreements hereinafter
expressed, the parties agree as follows:

                                    Section 1

                     Sale and Purchase of the Common Shares

         Subject to the terms and conditions of this Agreement, the Company will
issue and sell to VEBA and VEBA will purchase  from the Company,  at the Closing
provided for in Section 2, the Common Shares,  at a price per share equal to the
Purchase Price.

                                    Section 2

                                     Closing

         The sale of the Common  Shares to be purchased by VEBA shall take place
at the  offices of Bryan Cave LLP,  211 N.  Broadway,  Suite  3600,  St.  Louis,
Missouri  63102-2750  at 10:00 A.M.,  Central  Standard  Time, at a closing (the
"Closing") to be held on the date that is the Business Day immediately following
the  Calculation  Date;  provided  that in no event shall the date of Closing be
later than  December 30, 1998.  At the Closing,  the Company will deliver to the
Escrow Agent certificates for the Common Shares registered in VEBA's name (or in
the name of VEBA's nominee or assignee in accordance with Section 7.4),  against
delivery by VEBA to the Escrow Agent of immediately  available  funds by federal
wire transfer in the amount of the aggregate Purchase Price therefor.  After the
Closing the  certificates  for the Common Shares and such funds shall be held by
the Escrow  Agent  pursuant  to and in  accordance  with the terms of the Escrow
Agreement.  If at the Closing the Company shall fail to tender  certificates for
the Common Shares as provided  above in this Section 2, or any of the conditions
specified  in Section  3(a) shall not have been  fulfilled,  VEBA shall,  at its
election,  be relieved of all further obligations under this Agreement,  without
thereby waiving any other rights VEBA may have by reason of such failure or such
nonfulfillment.

                                    Section 3

                              Conditions to Closing

         (a) VEBA's  obligations  to purchase and pay for the Common  Shares are
subject  to the  fulfillment,  prior  to or at  the  Closing,  of the  following
conditions:

         3.1 Representations and Warranties.  The representations and warranties
of the Company  contained in this Agreement  shall be true and correct when made
and at the time of the Closing.

         3.2  Performance.  The Company shall have performed and complied in all
material  respects with all agreements and conditions  contained herein required
to be performed or complied with prior to or at the Closing.

         3.3  Compliance  Certificate.  VEBA shall have  received  an  Officer's
Certificate of the Company,  dated the date of the Closing and  satisfactory  in
form and substance to VEBA, in the name and on behalf of the Company, certifying
that the conditions specified in Section 3.1 and 3.2 have been fulfilled.

         3.4  Opinions  of  Counsel.  VEBA  shall have  received  at the time of
Closing the opinion of Bryan Cave LLP,  counsel for the  Company,  addressed  to
VEBA, dated the date of the Closing and substantially to the following effect:

         (i)  The  Company  is a  corporation  validly  existing  and is in good
    standing  under  the laws of the  State of  Delaware  and has all  requisite
    corporate  power and  authority to carry on its business as described in the
    Registration Statement;

         (ii) The Common Shares have been duly  authorized  and, when issued and
    delivered to VEBA against  payment  therefor in accordance with the terms of
    this Agreement, will be (A) validly issued, fully paid and nonassessable and
    (B) free of any  preemptive  or  similar  rights  under the  certificate  of
    incorporation or bylaws of the Company, or to the knowledge of such counsel,
    pursuant to any other agreement;

         (iii)  None  of the  issuance  and  sale  of  the  Common  Shares,  the
    execution,  delivery or  performance of this Agreement by the Company or the
    consummation  by  the  Company  of  the  transactions   contemplated  hereby
    constitutes or will constitute a violation or breach of, or a default under,
    the  certificate of  incorporation  or bylaws of the Company or any Material
    Agreement or will result in the creation or imposition  of any lien,  charge
    or  encumbrance  pursuant to any  Material  Agreement,  upon any property or
    assets of the Company or any of its  subsidiaries,  nor will any such action
    result in any violation of the Delaware General Corporation Law (the "DGCL")
    or any  existing  Federal or  Missouri  law,  regulation,  ruling  (assuming
    compliance  with  all  applicable  state  securities  and  Blue  Sky  laws),
    recognized by such counsel to be applicable to, or any judgment, injunction,
    order of decree known to such counsel,  of any Federal or Missouri  court to
    be applicable to, the Company,  its  subsidiaries or any of their respective
    properties   (provided,   the  term  "Material  Agreement"  shall  mean  any
    agreement,  indenture,  lease or other  instrument or agreement that is both
    (i)  an  exhibit  to the  Registration  Statement  and  (ii)  an  agreement,
    indenture,  lease or other  instrument  or agreement to which the Company or
    any of its  subsidiaries  is a party or by which any of their  properties or
    assets are bound);

         (iv) (A) The Company has the  corporate  power and  authority  to enter
    into this  Agreement  and to  issue,  sell and  deliver  the  Common  Shares
    pursuant to this Agreement, and (B) this Agreement has been duly authorized,
    executed  and  delivered  by the Company and is a legally  valid and binding
    agreement of the Company;

         (v)  No  consent,  approval,   authorization  or  other  order  of,  or
    registration or filing with, any Federal or Missouri court, regulatory body,
    administrative  agency or other  governmental  body,  agency or  official is
    required  to be obtained  by the  Company  (except as may be required  under
    state securities or Blue Sky laws governing the sale and distribution of the
    Shares) for the valid issuance and sale of the Common Shares; and

         (vi) Each of the Incorporated  Documents, as amended or supplemented by
    the Registration  Statement or otherwise,  as of the date hereof (and except
    for the  financial  statements  and the notes  thereto and the schedules and
    other  financial  and  statistical  data or  schedules  included  therein or
    omitted  therefrom,  as to which such counsel need not express any opinion),
    comply as to form in all  material  respects  with the  requirements  of the
    Securities Exchange Act of 1934, as amended (the "Exchange Act").

         In addition to the matters set forth  above,  such  opinion  shall also
contain a statement to the effect  that,  although  counsel has not  undertaken,
except as otherwise indicated in their opinion, to determine independently,  and
does not assume any  responsibility  for,  the accuracy or  completeness  of the
statements in the Registration  Statement,  such counsel has participated in the
preparation of the Registration  Statement and the Prospectus,  including review
and discussion of the contents thereof (including a review and discussion of the
contents of all Incorporated  Documents),  and nothing has come to the attention
of such  counsel  that has  caused  it to  believe  (i)  that  the  Registration
Statement   (including  the  Incorporated   Documents  but  excluding  any  VEBA
Information (as defined below)) contains any untrue statement of a material fact
or omits to state a material fact required to be stated  therein or necessary to
make  the  statements  therein  not  misleading  or  (ii)  that  the  Prospectus
(including the  Incorporated  Documents but excluding any VEBA  Information  (as
defined  below))  contains any untrue  statement of a material  fact or omits to
state a material fact necessary in order to make the statements  therein, in the
light of the circumstances  under which they were made, not misleading (it being
understood  that such  counsel  need  express  no  opinion  with  respect to the
financial statements and the notes thereto and the schedules and other financial
and statistical  data included or incorporated by reference in the  Registration
Statement  or the  Prospectus  or omitted  therefrom).  With respect to specific
matters with  respect to which Bryan Cave does not  represent  the Company,  the
foregoing  statement  may be delivered  by other  counsel  that  represents  the
Company with respect to such matters,  such counsel to be reasonably  acceptable
to VEBA.

         In  rendering  the  foregoing  opinion,  such  counsel may rely,  as to
matters  involving  laws of any  jurisdiction  other than Missouri or the United
States or the DGCL, upon opinions  addressed to VEBA of other counsel reasonably
acceptable  to VEBA;  provided  that insofar as any such opinion  relates to the
DGCL,  such  opinion  may be  delivered  by  Richards  Layton & Finger,  P.A. In
rendering  the opinion  specified in clause (iv) above such counsel shall assume
that, insofar is it relates to enforceability, that the laws of the State of New
York  are the  same as the  laws of the  State of  Missouri.  In  addition,  the
foregoing opinion may contain customary assumptions and qualifications.

         3.5  Secretary's  Certificate.  VEBA shall have received a Certificate,
dated the date of the Closing, of the Secretary or an Assistant Secretary of the
Company,  certifying as to the resolutions  adopted by the Board of Directors of
the Company or its Special Committee approving the documents and/or transactions
contemplated  hereby,  copies of which  resolutions  shall be  attached  to such
Certificate.

         3.6  Absence  of  Certain  Changes.  (i) There  shall not have been any
material  adverse  change in the capital  stock of the Company nor any  material
increase in the short-term or long-term debt of the Company and its subsidiaries
on a  consolidated  basis  (other  than in the  ordinary  course of  business or
pursuant to  agreements  with VEBA AG or its  affiliates)  from the date of this
Agreement;  (ii) there shall not have been, since the date of this Agreement any

not have any liabilities or obligations, direct or contingent (whether or not in
the  ordinary  course of  business),  that are  material  to the Company and its
subsidiaries, taken as a whole, other than those in existence on the date hereof
or those pursuant to any agreement with VEBA AG or its affiliates.

of its subsidiaries is a corporation duly incorporated,  validly existing and in
good standing under the laws of its  jurisdiction of  organization,  has all the
requisite corporate power and authority to carry on its business as described in
the  Registration  Statement and  Prospectus  and is qualified to do business in
every jurisdiction where such qualification or registration is required,  except
where the failure to qualify or register would not have,  individually or in the
aggregate,  a material  adverse  effect on the  condition  (financial or other),
business,  properties,  prospects,  net worth or  results of  operations  of the
Company and its subsidiaries taken as a whole (a "Material Adverse Effect").

         4.2  Authorization.  (a) The Company has taken all actions necessary to
authorize it (i) to execute,  deliver and perform all of its  obligations  under
this Agreement and (ii) to consummate the transactions contemplated hereby. This

limited by applicable  bankruptcy,  insolvency,  reorganization,  moratorium and

general  principles  of equity  (regardless  of whether such  enforceability  is
sought in equity or at law).

         (b) The Common  Shares have been duly  authorized  and, when issued and
delivered to VEBA against payment  therefor in accordance with the terms of this
Agreement,  will be validly issued, fully paid and nonassessable and free of any

proceeds  therefrom does not exceed $200 million,  none of the issuance and sale
of the Common Shares,  the execution,  delivery or performance of this Agreement
by the Company, the consummation by the Company of the transactions contemplated
hereby nor the  compliance  with the terms of this  Agreement  (A)  requires any
consent,  approval,  authorization  or other order of or  registration or filing
with, any court,  regulatory body,  administrative  agency or other governmental
body,  agency or official or conflicts or will conflict with or  constitutes  or
will constitute a breach of, or a default under,  the certificate or articles of
incorporation or bylaws, or other  organizational  documents,  of the Company or
any of its subsidiaries or (B) conflicts or will conflict with or constitutes or
will constitute a breach of, or a default under, any agreement, indenture, lease
or other  instrument to which the Company or any of its  subsidiaries is a party
or by which any of them or any of their  respective  properties may be bound, or
violates or will violate any  statute,  law,  regulation  or filing or judgment,
injunction, order or decree applicable to the Company or any of its subsidiaries
or any of  their  respective  properties,  or will  result  in the  creation  or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or any of its  subsidiaries  pursuant to the terms of any  agreement  or
instrument  to which any of them is a party or by which any of them may be bound
or to which any of the property or assets of any of them is subject  except for,
in the case of the foregoing clause (B), such violations which would not, either
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect.

         (b) Neither the Company nor any of its subsidiaries is in violation (A)
of  its  certificate  or  articles  of  incorporation   or  by-laws,   or  other
organizational  documents,  or (B)  of any  law,  ordinance,  administrative  or
governmental  rule  or  regulation  applicable  to  the  Company  or  any of its
subsidiaries,  including, without limitation, (i) any foreign, Federal, state or
local law or regulation  relating to the  protection of human health and safety,
the  environment  or  hazardous or toxic  substances  or wastes,  pollutants  or
contaminants  ("Environmental  Laws"), (ii) any Federal or state law relating to
discrimination  in the hiring,  promotion or pay of employees or any  applicable
federal or state wages and hours laws,  or (iii) any  provisions of the Employee
Retirement  Income  Security  Act  or  the  rules  and  regulations  promulgated
thereunder   (collectively,   "ERISA"),  or  of  any  decree  of  any  court  or
governmental  agency or body having  jurisdiction over the Company or any of its
subsidiaries  except  for,  in  the  case  of the  foregoing  clause  (B),  such
violations which would not, either individually or in the aggregate,  reasonably
be expected to have a Material Adverse Effect.

         (c) Neither the  Company nor any of its  subsidiaries  is in default in
the performance of any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or in any other agreement,
indenture,  lease  or  other  instrument  to  which  the  Company  or any of its
subsidiaries  is a party  or by  which  any of them or any of  their  respective
properties  may be bound,  except for such  defaults  which  would  not,  either
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect.

         4.5  Registration  Statement  and  Prospectus.   (a)  The  Registration
Statement  does not contain an untrue  statement  of a material  fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements therein not misleading, and the Prospectus does not contain an untrue
statement of material fact or omit to state a material  fact  necessary in order
to make the statements,  in light of the  circumstances  in which they are made,
not misleading,  except that this  representation and warranty does not apply to
statements in or omissions  from the  Registration  Statement or the  Prospectus
relating to the VEBA Information.

         (b)  The  historical  financial   statements,   together  with  related
schedules and notes, included in the Registration  Statement and the Prospectus,
comply  as to  form  in all  material  respects  with  the  requirements  of the
Securities  Act of 1933,  as amended (the  "Securities  Act");  such  historical
financial statements,  together with related schedules and notes, present fairly
the  consolidated  financial  position,  results of  operations,  cash flows and
changes in the  financial  position of the  entities to which they relate on the
basis stated in the  Registration  Statement at the respective  dates or for the
respective  periods to which they apply;  such statements and related  schedules
and notes have been prepared in accordance  with generally  accepted  accounting
principles  consistently  applied  through  the  periods  involved,   except  as
disclosed therein; and the other financial and statistical  information and data
included  in the  Registration  Statement  and the  Prospectus,  are  accurately
presented in all material respects and, to the extent applicable,  prepared on a
basis consistent in all material respects with such financial statements and the
books and records of the entities to which they relate.

         4.6 Permits. The Company and each of its subsidiaries has such permits,
licenses, franchises and authorizations including, without limitation, under any
applicable   Environmental  Laws,  of  governmental  or  regulatory  authorities
("permits") as are necessary to own its respective properties and to conduct its
business  subject to such  qualifications  and exceptions as may be set forth in
the Registration  Statement and Prospectus and as would not,  individually or in
the aggregate,  reasonably be expected to have a Material  Adverse  Effect;  the
Company  and  each of its  subsidiaries  has  fulfilled  and  performed  all its
material  obligations  with respect to such permits subject in each case to such
qualifications as may be set forth in the Registration  Statement and Prospectus
and no event has occurred which allows, or after notice or lapse of time or both
would allow,  revocation or termination thereof or results in any other material
impairment  of the rights of the holder of any such permit  subject in each case
to such  qualifications  as may be set forth in the  Registration  Statement and
Prospectus.

         4.7 Incorporated Documents. The Incorporated Documents heretofore filed
with the Commission,  when they were filed (or, if any amendment with respect to
any such document was filed,  when such  amendment was filed),  conformed in all
material  respects with the  requirements  of the Exchange Act and the rules and
regulations  thereunder,  and any further Incorporated  Documents so filed will,
when they are filed,  conform in all material  respects with the requirements of
the Exchange Act and the rules and regulations thereunder; no such document when
it was filed (or, if an amendment  with respect to any such  document was filed,
when such  amendment was filed),  contained  any untrue  statement of a material
fact or  omitted  to state a  material  fact  required  to be stated  therein or
necessary in order to make the statements therein, in light of the circumstances
under  which  they were  made,  not  misleading;  and any  further  Incorporated
Documents so filed will, when they are filed,  not contain any untrue  statement
of a  material  fact or omit to state a  material  fact  required  to be  stated
therein or necessary in order to make the  statements  therein,  in light of the
circumstances  under  which  they are made,  not  misleading,  except  that this
representation and warranty will not apply to any VEBA Information.

         4.8  No Material Adverse Change.  (a) No Material Adverse Change. Since
December 31, 1997 except as set forth in the Registration  Statement,  there has
not been a  material  adverse  change in the  condition  (financial  or  other),
business,  prospects,  properties,  net worth or  results of  operations  of the
Company  and its  subsidiaries  on a  consolidated  basis (a  "Material  Adverse
Change").

         4.9  Litigation.  Except to the  extent  set forth in the  Registration
Statement,  there  are no  actions,  claims,  suits,  citations  or  proceedings
(including,  without limitation, an investigation or partial proceeding, such as
a  deposition)  pending,  or  to  the  knowledge  of  the  Company,   threatened
("Proceedings")  against or affecting the Company or any of its  subsidiaries or
any of their respective properties or assets, that either individually or in the
aggregate are reasonably  likely to have a Material Adverse Effect.  There is no
Proceeding seeking to restrain, enjoin, prevent the consummation of or otherwise
challenge this Agreement, the Rights Offering, the issuance of the Common Shares
or the  transactions  contemplated  hereby.  Neither  the Company nor any of its
subsidiaries is subject to any judgment,  order,  decree,  rule or regulation of
any court,  governmental authority or arbitration board or tribunal that has had
a Material Adverse Effect or, except to the extent set forth in the Registration
Statement, that could reasonably be expected to have a Material Adverse Effect.

         4.10   Private Offering.  Assuming  the  truth and  correctness  of the
representations  and warranties  set forth in Section 6 hereof,  the sale of the
Common Shares hereunder is exempt from the registration and prospectus  delivery
requirements of the Securities Act.

         4.11   No Stabilization or Manipulation.   The  Company  has not taken,
directly or  indirectly,  any action  designed to cause or to result in, or that
has  constituted  or which  might  reasonably  be expected  to  constitute,  the
stabilization or manipulation of the price of any security of the Company.

                                    Section 5

                            Expenses; Indemnification

         5.1   Expenses.  If the transactions contemplated by this Agreement are
not  consummated  (other  than  because  of  VEBA's  breach  of its  obligations
hereunder),  the Company agrees to reimburse VEBA and its affiliates (as defined
in the Securities  Act),  other than the Company and its  subsidiaries,  for all
reasonable  out-of-pocket  expenses  (including  reasonable fees and expenses of
counsel)  incurred by VEBA and such affiliates in connection with this Agreement
and the  transactions  contemplated  hereby.  Notwithstanding  anything  in this
Agreement to the contrary,  the provisions of this Section 5.1 shall survive the
termination of this Agreement.

         5.2 Indemnification. (a) In addition to all other sums due hereunder or
provided for in this Agreement, the Company hereby agrees, without limitation as
to time, to indemnify VEBA and its affiliates,  directors,  officers, employees,
counsel,  agents  or  representatives   (collectively,   the  "VEBA  Indemnified
Parties")  against,  and hold each of them harmless  from, to the fullest extent
lawful, all losses,  claims,  damages,  liabilities,  costs (including,  without
limitation,   costs  of   preparation   and  reasonable   attorneys'   fees  and
disbursements) and expenses,  including expenses of investigation (collectively,
"Losses"), incurred by each of them and arising out of or in connection with (i)
this  Agreement,  (ii) a breach of any  representation,  warranty,  covenant  or
agreement of the Company hereunder or (iii) the transactions contemplated hereby
(or any other  document or instrument  executed  herewith or pursuant  hereto or
thereto)  whether or not the  transactions  contemplated  by this  Agreement are
consummated and whether or not any VEBA  Indemnified  Party is a formal party to
any  proceeding.  The Company  agrees to reimburse  any VEBA  Indemnified  Party
promptly for all such Losses as they are incurred by such VEBA Indemnified Party
(regardless  of  whether  it is or  may  be  ultimately  determined  that a VEBA
Indemnified Party is not entitled to indemnification hereunder). The obligations
of the  Company  to each VEBA  Indemnified  Party  hereunder  shall be  separate
obligations,  and the  Company's  liability to any such VEBA  Indemnified  Party
hereunder  shall not be extinguished  solely because any other VEBA  Indemnified
Party is not entitled to indemnity  hereunder.  The  obligations  of the Company
under this Section 5.2 shall  survive any transfer of the Common  Shares by VEBA
and the termination of this Agreement. Notwithstanding the foregoing, (x) to the
extent (A) the compliance certificate delivered pursuant to Section 3.3 contains
any exceptions and (B) VEBA  nevertheless  elects to consummate the transactions
contemplated  under  this  Agreement,  the  Company  shall not be  obligated  to
indemnify,  hold harmless or  contribute  to the Losses of any VEBA  Indemnified
Party (or reimburse its related  expenses) with respect to such exceptions under
this  Section  5.2 and VEBA  shall  not have any  claim  or  remedy  under  this
Agreement with respect to such excepted matters (except, in both such instances,
to the extent such Losses result from an inaccuracy contained in such compliance
certificate),  and (y) the Company  shall not be  obligated to  indemnify,  hold
harmless or contribute to the Losses of any VEBA Indemnified Party (or reimburse
its related  expenses) to the extent any Loss arises out of or is in  connection
with a claim made pursuant to clause (i) and/or (iii) of this Section 5.2(a) and
results  from the  wrongful  act or omission of such VEBA  Indemnified  Party or
results  from an act or  omission  with  respect  to which a court of  competent
jurisdiction  would find such VEBA  Indemnified  Party  liable or  culpable.  In
addition,  the Company  shall not be obligated to  indemnify,  hold  harmless or
contribute to the Losses of any VEBA Indemnified Party (or reimburse its related
expenses) to the extent any Loss arises out of or is in connection  with a claim
(x) made  pursuant  to clause (i) and/or  (iii) of this  Section  5.2(a) and (y)
originally brought, commenced or asserted by a VEBA Indemnified Party.

         (b) In  addition  to  all  other  consideration  provided  for in  this
Agreement,  VEBA hereby agrees,  without limitation as to time, to indemnify the
Company and its subsidiaries, directors, officers, employees, counsel, agents or
representatives  (collectively,  the "Company Indemnified Parties") against, and
hold each of them  harmless  from,  to the  fullest  extent  lawful,  all Losses
incurred by each of them and arising  out of or in  connection  with a breach of
any representation, warranty, covenant or agreement of VEBA hereunder whether or
not the transactions  contemplated by this Agreement are consummated and whether
or not any Company  Indemnified Party is a formal party to any proceeding.  VEBA
agrees to reimburse any Company  Indemnified  Party promptly for all such Losses
as they are incurred by such Company Indemnified Party (regardless of whether it
is or may be  ultimately  determined  that a  Company  Indemnified  Party is not
entitled to indemnification  hereunder). The obligations of VEBA to each Company
Indemnified Party hereunder shall be separate obligations,  and VEBA's liability
to any such Company Indemnified Party hereunder shall not be extinguished solely
because  any  other  Company  Indemnified  Party is not  entitled  to  indemnity
hereunder.  The  obligations  of VEBA under this  Section 5.2 shall  survive any
transfer of the Common Shares by VEBA and the termination of this Agreement.

         (c) The procedures set forth in Section 8(c) of the Registration Rights
Agreement  dated July 12,  1995  between the  Company  and Huls  Corporation  (a
predecessor to VEBA) shall govern any  indemnification  pursuant to this Section
5.2.

         (d)  If  the  indemnification  provided  for  in  this  Section  5.2 is
unavailable  to, or  insufficient  to hold harmless,  any  indemnified  party in
respect of any Losses referred to herein,  then an indemnifying party shall have
an obligation  to  contribute to the amount paid or payable by such  indemnified
party as a result of such Losses in such proportion as is appropriate to reflect
its relative  fault, on the one hand, and such  indemnified  party, on the other
hand,  in connection  with the actions which  resulted in such Losses as well as
any other relevant equitable  considerations.  The amount paid or payable by any
such  person  as a result of the  Losses  referred  to above  shall be deemed to
include, subject to the limitations set forth in Section 5.2, any legal or other
fees or  expenses  reasonably  incurred by such  Person in  connection  with any
investigation, lawsuit or legal or administrative action or proceeding.

         (e) The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5.2 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in subsection (c) of this Section 5.2.

         5.2 Arbitration. (a) Resolution of any and all disputes arising from or
in connection with the  determination of to what extent, if any, a claim is made
pursuant to clause (i) and/or (iii) of Section 5.2(a) as compared to clause (ii)
of  Section  5.2(a)  or to what  extent,  if any,  a VEBA  Indemnified  Party is
entitled to indemnification  pursuant to clause (y) in the penultimate  sentence
of Section 5.2(a) ("Disputes"),  shall be exclusively governed by and settled in
accordance  with the  provisions of this Section;  provided,  that the foregoing
shall not preclude  equitable or other judicial relief to enforce the provisions
hereof or to preserve the status quo pending  resolution of Disputes  hereunder.
Each party to this  Agreement  (each a "Party" and together the  "Parties")  may
commence  proceedings  hereunder  by  delivery  of written  notice  providing  a
reasonable  description of the Dispute to the other Party, including a reference
to this Section (the "Dispute Notice").

         (b) The Parties shall first  attempt in good faith to resolve  promptly
any Dispute by negotiations  between  executives who have authority to settle it
(as to each Party, an "Executive"). Not later than 35 days after delivery of the
Dispute Notice,  each Party shall designate an Executive and meet with the other
Party's  Executive at a reasonably  acceptable time and place, and thereafter as
such  Executives  deem  reasonably  necessary.  The  Executives  shall  exchange
relevant  information  and  endeavor to resolve the  Dispute.  Prior to any such
meeting,  each  Party's  Executive  shall  advise  the  other  as to  any  other
individuals  who will attend such  meeting.  All  negotiations  pursuant to this
Section shall be  confidential  and shall be treated as compromise  negotiations
for purposes of Rule 408 of the Federal  Rules of Evidence and  similarly  under
other federal and state rules of evidence.

         (c) Except to the  extent the  Parties  agree to  continue  proceedings
pursuant to paragraph (b) hereof,  the Parties shall,  commencing not later than
35 days after the date of delivery of the Dispute Notice, endeavor to settle the
Dispute by Mediation  pursuant to the Center for Public Resources  ("CPR") Model
Procedure  for  Mediation  of Business  Disputes,  as amended from time to time,
and/or  according to such other or additional rules or procedures as the Parties
may agree.  The neutral third party in such Mediation  shall be as agreed by the
Parties or, failing such agreement, selected with the assistance of the CPR.

         (d) (1) The Parties  hereby agree to submit all Disputes to arbitration
under the following  provisions,  which  arbitration  shall be final and binding
upon  the  Parties,  their  successors  and  assigns,  and  that  the  following
provisions constitute a binding arbitration clause under applicable law.

         (2) Either Party may initiate arbitration of a Dispute by delivery of a
demand therefor (the "Arbitration Demand") to the other Party not sooner than 60
days  after  the  date  of  delivery  of the  Dispute  Notice  but  at any  time
thereafter;  provided,  that if a Party (the  "Non-Cooperative  Party") does not
cooperate in the procedures  provided under  paragraph (b) or paragraph (c), the
other  Party  may   initiate   arbitration   at  such   earlier   time  as  such
non-cooperation shall become reasonably apparent, and the arbitrators may assess
against  the  Non-Cooperative  Party  damages  and  expenses  arising  from such
non-cooperation,  including  attorney's fees and expenses and Arbitration  Costs
(as defined below) in connection with arbitration hereunder.

         (3) The  arbitration  shall be conducted in New York by one  arbitrator
selected by  agreement  of the Parties not later than 10 days after  delivery of
the  Arbitration  Demand or, failing such agreement,  appointed  pursuant to the
Commercial Arbitration Rules of the American Arbitration Association, as amended
from time to time (the "AAA Rules").  If an arbitrator  becomes unable to serve,
his or her successor(s) shall be similarly selected or appointed.

         (4)  The  arbitration  shall  be  conducted  pursuant  to  the  Federal
Arbitration Act and the Missouri Uniform  Arbitration Act and such procedures as
the Parties may agree or, in the absence of or failing such agreement,  pursuant
to the AAA Rules. Notwithstanding the foregoing: (A) each party shall be allowed
to  conduct  discovery  through  written  requests  for  information,   document
requests, requests for stipulations of fact, and depositions; (B) the nature and
extent of such discovery  shall be determined by the Panel,  taking into account
the needs of the Parties and the  desirability of making  discovery  expeditious
and   cost-effective;   (C)  the  Panel  may  issue   orders  to   protect   the
confidentiality of information to be disclosed in discovery; and (D) the Panel's
discovery rulings may be enforced in any court of competent jurisdiction.

         (5) All hearings shall be conducted on an expedited  schedule,  and all
proceedings  shall be  confidential.  Either  Party  may at its  expense  make a
stenographic record thereof.

         (6) The Panel shall  complete all hearings not later than 90 days after
selection or  appointment.  The Panel's  decision  shall be in writing and shall
specify the factual and legal bases for the decision.  The Panel shall apportion
all costs and  expenses  of the  arbitration,  including  the  Panel's  fees and
expenses  and fees and  expenses of experts  ("Arbitration  Costs")  between the
prevailing and  non-prevailing  Party as the Panel deems fair and reasonable and
consistent  with the principles and provisions of Section 5.2. In  circumstances
where (A) a Dispute has been  asserted or defended  against on grounds  that the
Panel  deems  manifestly  unreasonable,  or (B)  the  non-prevailing  Party  has
rejected  participation  in procedures under paragraph (b) or (c), the Panel may
assess all Arbitration Costs against the non-prevailing Party and may include in
the award the prevailing Party's attorney's fees and expenses in connection with
any and all proceedings  under this Section.  Any assessment or apportionment of
Arbitration  Costs in accordance  with the foregoing  sentences shall not affect
the amount,  if any, an  indemnified  party is entitled to receive on account of
any Losses  pursuant  to the  provisions  of Section  5.2.  Notwithstanding  the
foregoing,  in no event may the Panel  award  multiple,  punitive  or  exemplary
damages.

         (7) Either Party may assert  appropriate  statutes of  limitation  as a
defense in  arbitration;  provided,  that upon delivery of a Dispute  Notice any
such statute shall be tolled pending resolution hereunder.

         (e)  Confidentiality  -  Notice.  Each  Party  shall  notify  the other
promptly,  and in any  event  prior to  disclosure  to any third  person,  if it
receives  any  request for access to  confidential  information  or  proceedings
hereunder.

                                    Section 6

                            Purchase for Investment;
                      Other Representations and Warranties

         VEBA represents and warrants on and as of the date hereof and as of the
date of issuance of the Common Shares and, to the extent specified  below,  VEBA
agrees, as follows:

         6.1  Purchase for Investment. Subject to VEBA's right of assignment set
forth in Section 7.4, VEBA is  purchasing  the Common Shares for its own account
or for one or more  separate  accounts  maintained  by  VEBA,  in each  case for

                               Fax: (314) 279-5158

         7.7  Severability.  Any provision of this Agreement which is prohibited
or  unenforceable  in  any  jurisdiction  shall,  as to  such  jurisdiction,  be
ineffective  to the  extent  of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable  such  provision  in  any  other  jurisdiction.   There  shall  be
substituted for any such provision so rendered ineffective a provision which, as
far as legally possible, most nearly reflects the intent of the parties hereto.

         7.8 Use of Proceeds. The Company hereby agrees to use the proceeds from
the sale of the Common  Shares in the manner and for the  purposes  specified in
the Registration Statement.

         7.9 Termination. Either party may terminate this Agreement if more than
an  aggregate  of 150  million  shares of Common  Stock  would be required to be
issued,  or more  than  $200  million  would  be  received  by the  Company,  in
connection  with the  consummation  of the  purchase  and sale of Common  Shares
contemplated  hereby  and  the  consummation  of the  Rights  Offering  and  the
transactions contemplated by the Standby Agreement dated the date hereof between
VEBA and the Company (the "Standby Agreement"). The Company shall have the right
to terminate this  Agreement if the Special  Committee of the Board of Directors
of the Company  determines in good faith,  after receiving the advice of outside
counsel,  that  proceeding  with the Rights Offering would result in a breach of
its fiduciary duties to the Company's stockholders under applicable law.

         7.10  Taxes.  In the event that VEBA and its  affiliates'  ownership of
Common  Stock,  entitles  VEBA to include the  Company in the VEBA  consolidated
federal income tax return,  VEBA and the applicable VEBA affiliates  shall enter
into a tax sharing or  affiliation  agreement  with the Company.  Such agreement
shall provide that the inclusion of the Company in the VEBA consolidated federal
income tax return will not be  detrimental to the Company for federal income tax
purposes as compared with the federal income tax treatment of the Company had it
not been includible in the VEBA consolidated  federal income tax return and such
agreement  shall be in form and substance  reasonably  acceptable to the Company
and VEBA.

         7.11  Comfort  Letter.  The Company agrees to endeavor in good faith to
obtain the receipt of the Comfort Letter described in Section 3.9.

         7.12  Counterparts.  This  Agreement  may be  executed in any number of
counterparts,  and by each party hereto in separate counterparts,  each of which
counterpart shall be an original, but all of which together shall constitute one
and the same Agreement.  Delivery of an executed counterpart of a signature page
of this  Agreement  by  telecopier  shall be effective as delivery of a manually
executed counterpart of this Agreement.

         7.13  Headings. The section headings in this Agreement are for purposes
of reference only and shall not limit or define the meaning hereof.

         7.14  WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO IRREVOCABLY AND
UNCONDITIONALLY  WAIVES  ALL  RIGHT TO TRIAL BY JURY IN ANY  LEGAL OR  EQUITABLE
ACTION,  SUIT,  PROCEEDING OR COUNTERCLAIM  (WHETHER BASED ON CONTRACT,  TORT OR
OTHERWISE)  ARISING OUT OF OR RELATING TO THIS  AGREEMENT,  THE SECURTIES OR ANY
TRANSACTION  CONTEMPLATED  HEREBY OR THEREBY,  THE SUBJECT  MATTER OF ANY OF THE
FOREGOING  OR THE  ACTIONS OF ANY PARTY  HERETO OR  THERETO IN THE  NEGOTIATION,
ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF OR THEREOF.

         7.15  GOVERNING  LAW.  THIS AGREEMENT AND (UNLESS  OTHERWISE  EXPRESSLY
PROVIDED)  ALL  AMENDMENTS  AND  SUPPLEMENTS  TO, AND ALL  CONSENTS  AND WAIVERS
PURSUANT TO, THIS  AGREEMENT  SHALL BE GOVERNED BY, AND  CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

         7.16  Registration  Statement.  Any reference in this  Agreement to the
Registration  Statement shall be to the most recent Registration  Statement,  as
filed with the Commission  (notwithstanding that such Registration  Statement is
subject to completion and has not yet been declared effective by the Commission)
or to the extent no  Registration  Statement has been filed with the Commission,
the Company's  draft  Registration  Statement  attached hereto as Schedule A. In
addition, any reference in this Agreement to the Registration Statement shall be
deemed to include any documents filed under the Exchange Act which have been (or
would  have  been had such  Registration  Statement  then  been  filed  with and
declared effective by the Commission) incorporated by reference therein. As used
herein, the term "Incorporated  Documents" means the documents which at the time
are (or would have been had such Registration Statement then been filed with and
declared  effective  by  the  Commission)   incorporated  by  reference  in  the
Registration Statement.

         7.17  Covenants of VEBA.  In further consideration of the agreements of
the Company herein contained, VEBA covenants as follows:

         VEBA has not taken and  during  the  period of the  calculation  of the
Purchase Price, will not take, directly or indirectly, any action designed to or
which  might be  reasonably  expected  to cause or  result in  stabilization  or
manipulation of the price of the Company's  Common Stock, and VEBA has no reason
to believe  that any such  action has been  taken by its  controlled  affiliates
other  than the  Company  and its  subsidiaries,  and  during  the period of the
calculation of the Purchase Price, will not permit any such controlled affiliate
to take such action.

         7.18  Waiver of Rights.     Assuming consummation  of the issuance  and
purchase  of  the  Common  Shares  in  accordance  with  this  Agreement,   VEBA
acknowledges  and agrees  that  neither  VEBA nor any  assignee of its Shares or
assignee of its rights under this Agreement will be entitled to any distribution
of Rights from the Company in the Rights Offering.  If VEBA transfers any shares
of Common Stock prior to the Record Date of the Rights Offering, VEBA will cause
any such transferee to agree that it will not be entitled to any distribution of
Rights from the Company in the Rights Offering with respect to such shares.

         7.19  Restricted  Nature of Shares.  VEBA  acknowledges that the Common
Shares,  in its hands,  will be restricted  securities  under the Securities Act
which  may not be sold or  offered  for  sale  in the  absence  of an  effective
registration  statement as to such Common Shares under the  Securities Act or an
opinion of counsel  satisfactory  to the Company that such  registration  is not
required. VEBA agrees it will not transfer, by way of gift or otherwise, or sell
the Common  Shares or any part  thereof,  unless  such  Common  Shares have been
registered  under the Securities Act and any applicable state securities laws or
it first obtains, at its own expense, if requested by the Company, an opinion of
counsel reasonably  satisfactory to the Company that the transfer of such Common
Shares may be effected  without  registration  under the  Securities Act and any
applicable  state  securities  laws.  VEBA  acknowledges  that the  certificates
evidencing the Common Shares will contain a legend to such effect.

                  IN WITNESS WHEREOF, each of the parties hereto has caused this
Agreement to be executed as of the date first above written.

                                STANDBY AGREEMENT

         THIS STANDBY  AGREEMENT (the "Agreement") is entered into as of October
22, 1998, by and among VEBA Corporation,  a Delaware corporation  ("VEBA"),  and
MEMC Electronic Materials, Inc., a Delaware corporation (the "Company").

                                    RECITALS

         A. Pursuant to a stock purchase  agreement,  dated the date hereof (the
"Stock Purchase Agreement"), the Company proposes to issue to VEBA approximately
$106  million  of its  Common  Stock,  par value  $0.01 per share  (the  "Common
Stock"),  at a purchase price per share  determined in accordance with the Stock
Purchase Agreement (the "VEBA Purchase Price") (the transactions contemplated by
the Stock  Purchase  Agreement  being  hereinafter  referred to as the  "Private
Placement"); and

         B. The Company also proposes to issue (the "Rights Offering"), upon the
terms and subject to the conditions set forth in the Prospectus (as  hereinafter
defined),  rights (the  "Rights") to purchase  shares of its Common Stock.  Each
Right will be exercisable at a price per share to be set forth in the Prospectus
(the  "Subscription  Price") and  evidenced by  transferable  certificates  (the
"Rights Certificates").  The Subscription Price and the VEBA Purchase Price will
be identical.  The date on which the Rights  Offering  expires is referred to as
the  "Expiration  Date" and the time  which the Rights  Offering  expires on the
Expiration  Date is  referred  to as the  "Expiration  Time." The Rights and the
Common Stock issuable and issued upon exercise thereof are hereinafter sometimes
collectively referred to as the "Securities."

         NOW,  THEREFORE,  in  consideration  of the  recitals  and  the  mutual
covenants,  representations,  warranties,  conditions and agreements hereinafter
expressed, the parties agree as follows:

                                    ARTICLE I
               STANDBY COMMITMENT FOR PURCHASE AND SALE OF SHARES

         1.1.  Registration  Statement  and  Prospectus;  Public  Offering.  The
Company   will  file  with  the   Securities   and  Exchange   Commission   (the
"Commission"),  pursuant  to  the  Securities  Act  of  1933,  as  amended  (the
"Securities  Act"),  and the  published  rules and  regulations  adopted  by the
Commission  under it (the  "Rules"),  a  registration  statement  on Form S-3 or
another  appropriate  form under the  Securities  Act,  including a  preliminary
prospectus,  relating to the Securities,  and will use its reasonable efforts to
permit  such  registration  statement  to  become  effective.  The  registration
statement as amended at the time it becomes  effective (the  "Effective  Date"),
including all financial statements and all exhibits set forth therein, is called
the "Registration Statement," and the prospectus relating to the Rights Offering
included in the Registration  Statement (including  information deemed a part of
such Registration  Statement pursuant to Rule 430A under the Securities Act), is
called the  "Prospectus."  Any reference in this  Agreement to the  Registration
Statement or  Prospectus  shall be deemed to refer to and include the  documents
incorporated  by  reference  therein  as of the  date of any  such  Registration
Statement or Prospectus,  as the case may be, and any reference to any amendment
or supplement  to the  Registration  Statement or Prospectus  shall be deemed to
refer to and include any  documents  filed after such date under the  Securities
Exchange Act of 1934, as amended (the "Exchange  Act") which,  upon filing,  are
incorporated  by  reference  therein.  As used  herein,  the term  "Incorporated
Documents"  means the documents which at the time are  incorporated by reference
in the  Registration  Statement or the Prospectus or any amendment or supplement
thereto.

         1.2. Purchase and Sale of Shares. On the basis of the  representations,
warranties and other agreements  herein  contained,  VEBA agrees to purchase and
the Company agrees to sell at the Subscription  Price any shares of Common Stock
offered in the Rights  Offering and not  otherwise  subscribed  for by the other
stockholders  of the Company prior to the Expiration Time  ("Shares"),  but only
after  satisfaction  in full of the  Oversubscription  Privileges  of all  other
stockholders of the Company.  Notwithstanding the foregoing,  but subject to the
provisions  of Section 3.1,  VEBA agrees that,  to the extent the rounding up of
Rights  distributed  to  stockholders  or any other reason  causes the aggregate
proceeds from the Stock Purchase Agreement,  the Rights Offering and pursuant to
this  Agreement  to exceed $200  million (or the  aggregate  number of shares of
Common Stock issued pursuant to both transactions to exceed 150 million shares),
the number of shares of Common  Stock sold by the Company and  purchased by VEBA
pursuant  to this  Agreement  shall  be  reduced,  in order  that the  aggregate
proceeds from the Private  Placement,  the Rights  Offering and pursuant to this
Agreement  shall not exceed $200 million and the  aggregate  number of shares of
Common Stock issued in such transactions  shall not exceed 150 million.  If VEBA
or its  affiliates  purchase  any  Rights,  on the New York  Stock  Exchange  or
otherwise,  during the Rights  Offering,  VEBA  agrees  that  neither it nor its
affiliates  (other than the  Company and its  subsidiaries)  will  exercise  its
Oversubscription Privilege with respect to such Rights.

         1.3.  Payment  and  Delivery.  VEBA  shall  pay for the  Shares by wire
transfer of  immediately  available  funds to a bank account  designated  by the
Company and the Company  shall  deliver the Shares at the office of Chadbourne &
Parke LLP, 30 Rockefeller  Plaza,  New York, New York 10112,  at 10:00 A.M., New
York City  time,  on the same  business  day as the  shares of Common  Stock are
issued to the holders of Rights in the Rights Offering,  which date shall be the
first business day following the Expiration Date, or at such other date or place
as shall be determined by agreement between VEBA and the Company.  This date and
time are sometimes  referred to as the "Closing  Date." On the Closing Date, the
Company shall  deliver or cause to be delivered  certificates  representing  the
Shares to VEBA against payment as aforesaid. Upon delivery, the certificates for
the Shares shall be registered in the name of VEBA (or its permitted assignee in
accordance with Section 6.4) and in such  denominations as VEBA shall request in
writing not less than two full business days prior to the Closing Date.

                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES

         2.1.  Representations  and  Warranties  of  the  Company.  The  Company
represents and warrants to and agrees with VEBA that:

              (a) The  Company  is a  corporation  duly  organized  and  validly
existing,  is in good standing under the laws of the State of Delaware,  and has
all  requisite  corporate  power  and  authority  to  carry on its  business  as
described in the Registration Statement and the Prospectus.  The Company is duly
qualified  as a  foreign  corporation  and is in  good  standing  in  all  other
jurisdictions in which such  qualification is required,  provided however,  that
the Company  need not be  qualified  in a  jurisdiction  in which its failure to
qualify would not,  individually  or in the aggregate,  have a material  adverse
effect on the condition (financial or other), business,  properties,  prospects,
net worth or results of operations of the Company and its subsidiaries  taken as
a whole (a "Material Adverse Effect").

              (b) No person is entitled to any  preemptive or similar  rights to
subscribe for the Shares.

              (c) All the outstanding shares of Common Stock of the Company have
been duly authorized and validly issued,  are fully paid and  nonassessable  and
are free of any  preemptive  or similar  rights.  The Rights,  the Common  Stock
issuable  upon  exercise  of the  Rights and the Shares to be issued and sold to
VEBA pursuant to this Agreement have been duly  authorized and such Common Stock
and Shares,  when issued and paid for,  will be validly  issued,  fully paid and
non-assessable;  such  securities  are not subject to any  preemptive or similar
rights.  The capital stock of the Company  conforms in all material  respects to
the description thereof in the Registration Statement and the Prospectus.

              (d)  Neither  the  issuance  and  sale  of  the  Securities,   the
execution,  delivery  or  performance  of this  Agreement  by the  Company,  the
consummation  by the  Company  of the  transactions  contemplated  hereby by the
Company  (including  the  issuance  and  sale of the  Shares  to  VEBA)  nor the
compliance  with the terms of the Rights and this  Agreement  (A)  requires  any
consent,  approval,  authorization  or other order of or  registration or filing

National Association of Securities Dealers, Inc., compliance with the securities
or Blue Sky laws of various  jurisdictions  and compliance with the rules of the

or will constitute a breach of, or a default under,  the certificate or articles
of incorporation or bylaws, or other organizational documents, of the Company or
any of its subsidiaries or (B) conflicts or will conflict with or constitutes or
will constitute a breach of, or a default under, any agreement, indenture, lease
or other  instrument to which the Company or any of its  subsidiaries is a party
or by which any of them or any of their  respective  properties may be bound, or
violates or will violate any  statute,  law,  regulation  or filing or judgment,
injunction, order or decree applicable to the Company or any of its subsidiaries
or any of  their  respective  properties,  or will  result  in the  creation  or
imposition of any lien, charge or encumbrance upon any property or assets of the
Company or any of its  subsidiaries  pursuant to the terms of any  agreement  or
instrument  to which any of them is a party or by which any of them may be bound
or to which any of the property or assets of any of them is subject  except for,
in the case of the foregoing clause (B), such violations which would not, either
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect.

              (e) The  Registration  Statement  in the form in which it  becomes
effective and also in such form as it may be when any  post-effective  amendment
thereto shall become  effective,  will comply in all material  respects with the
provisions  of the  Securities  Act and will not at any such  times  contain  an
untrue statement of a material fact or omit to state a material fact required to
be stated  therein or necessary to make the statements  therein not  misleading,
and the Prospectus  and any supplement or amendment  thereto when filed with the
Commission  under  Rule  424(b)  under  the  Securities  Act will  comply in all
material  respects with the provisions of the Securities Act and will not at any
such  time  contain  an untrue  statement  of  material  fact or omit to state a
material  fact  necessary  in  order  to make  the  statements,  in light of the
circumstances  in  which  they  are  made,  not  misleading,  except  that  this
representation  and warranty does not apply to the VEBA  Information (as defined
below).

              (f) There are no legal or governmental  proceedings pending or, to
the  knowledge  of the  Company,  threatened  against  the Company or any of its
subsidiaries,  or to which the Company or any of its  subsidiaries,  or to which
any of their respective properties is subject, that are required to be described
in the  Registration  Statement  or the  Prospectus  but are not so described as
required.

              (g)  Neither  the  Company  nor  any  of  its  subsidiaries  is in
violation (A) of its  certificate or articles of  incorporation  or by-laws,  or
other organizational documents, or (B) of any law, ordinance,  administrative or
governmental  rule  or  regulation  applicable  to  the  Company  or  any of its
subsidiaries,  including, without limitation, (i) any foreign, Federal, state or
local law or regulation  relating to the  protection of human health and safety,
the  environment  or  hazardous or toxic  substances  or wastes,  pollutants  or
contaminants  ("Environmental  Laws"), (ii) any Federal or state law relating to
discrimination  in the hiring,  promotion or pay of employees or any  applicable
federal or state wages and hours laws,  or (iii) any  provisions of the Employee
Retirement  Income  Security  Act  or  the  rules  and  regulations  promulgated
thereunder   (collectively,   "ERISA"),  or  of  any  decree  of  any  court  or
governmental  agency or body having  jurisdiction over the Company or any of its
subsidiaries  except  for,  in  the  case  of the  foregoing  clause  (B),  such
violations which would not, either individually or in the aggregate,  reasonably
be expected to have a Material Adverse Effect.

              (h) Neither the Company nor any of its  subsidiaries is in default
in the  performance of any obligation,  agreement or condition  contained in any
bond,  debenture,  note or any other  evidence of  indebtedness  or in any other
agreement,  indenture,  lease or other instrument to which the Company or any of
its  subsidiaries is a party or by which any of them or any of their  respective
properties  may be bound,  except for such  defaults  which  would  not,  either
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect.

              (i) The  historical  financial  statements,  together with related
schedules and notes,  included in the Registration  Statement and the Prospectus
(and any  amendment or  supplement  thereto),  comply as to form in all material
respects with the requirements of the Securities Act; such historical  financial
statements,  together  with  related  schedules  and notes,  present  fairly the
consolidated financial position,  results of operations,  cash flows and changes
in  financial  position of the entities to which they relate on the basis stated
in the  Registration  Statement at the  respective  dates or for the  respective
periods to which they apply;  such  statements  and related  schedules and notes
have been prepared in accordance with generally accepted  accounting  principles
consistently  applied  throughout  the  periods  involved,  except as  disclosed
therein;  and the other financial and statistical  information and data included
in  the  Registration  Statement  and  the  Prospectus  (and  any  amendment  or
supplement  thereto),  are accurately presented in all material respects and, to
the extent  applicable,  prepared on a basis consistent in all material respects
with such  financial  statements  and the books and  records of the  entities to
which they relate.

              (j) The  execution  and  delivery of, and the  performance  by the
Company of its  obligations  under,  this  Agreement  have been duly and validly
authorized  by the  Company,  and this  Agreement  has been  duly  executed  and
delivered by the Company and constitutes the valid and legally binding agreement
of the Company,  enforceable  against the Company in accordance  with its terms,
except as rights to  indemnity  and  contribution  hereunder  may be  limited by
federal or state securities laws and subject to limitations on enforcement under
applicable   bankruptcy,   insolvency,   liquidation,   fraudulent   conveyance,
reorganization,  moratorium and other similar laws affecting  creditors'  rights
generally  and  to  general  equitable   principles  (whether  considered  in  a
proceeding in equity or at law).

              (k) Except as  disclosed  in the  Registration  Statement  and the
Prospectus,  subsequent to the respective  dates as of which such information is
given in the Registration Statement and the Prospectus:  neither the Company nor
any of its  subsidiaries  has  incurred any  material  liability or  obligation,
direct or  contingent,  or entered  into any  transaction,  not in the  ordinary
course of business,  that is material to the Company and its subsidiaries  taken
as a whole,  and there has not been any material change in the capital stock, or
material  increase in the short-term  debt or long-term  debt, of the Company or
any of its  subsidiaries  (except  pursuant  to  agreements  with  VEBA  and its
affiliates),  or any material adverse change, or any development  involving,  or
which may  reasonably  be expected to involve,  a prospective  material  adverse
change in the condition (financial or other), business,  properties,  prospects,
net worth or results of operations of the Company and its subsidiaries, taken as
a whole.

              (l) The Company  and each of its  subsidiaries  has such  permits,
licenses, franchises and authorizations including, without limitation, under any
applicable   Environmental  Laws,  of  governmental  or  regulatory  authorities
("permits") as are necessary to own its respective properties and to conduct its
business in the manner described in the  Registration  Statement and Prospectus,
subject to such qualifications as may be set forth in the Registration Statement
and Prospectus  and with such  exceptions as would not,  individually  or in the
aggregate, reasonably be expected to have a Material Adverse Effect; the Company
and each of its  subsidiaries  has  fulfilled  and  performed  all its  material
obligations with respect to such permits and no event has occurred which allows,
or after notice or lapse of time or both would allow,  revocation or termination
thereof or results in any other material  impairment of the rights of the holder
of any such  permit,  subject in each case to such  qualification  as may be set
forth in the Registration Statement and Prospectus.

              (m) The Incorporated  Documents  heretofore  filed, when they were
filed (or, if any amendment  with respect to any such  document was filed,  when
such  amendment  was  filed),  conformed  in  all  material  respects  with  the
requirements of the Exchange Act and the rules and regulations  thereunder,  and
any further  Incorporated  Documents so filed will, when they are filed, conform
in all material respects with the requirements of the Exchange Act and the rules
and  regulations  thereunder;  no such  document  when it was filed  (or,  if an
amendment  with respect to any such document was filed,  when such amendment was
filed),  contained any untrue statement of a material fact or omitted to state a
material  fact  required to be stated  therein or necessary in order to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading;  and no such further document, when it is filed, will contain an
untrue  statement  of a  material  fact or will  omit to state a  material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading,  except that this representation and warranty does not apply to VEBA
Information.

              (n) The Company has not taken, directly or indirectly,  any action
designed  to cause or to  result  in,  or that has  constituted  or which  might
reasonably be expected to constitute,  the  stabilization or manipulation of the
price of any security of the Company to facilitate the issuance of the Rights or
the sale or resale of the Common Stock  issuable  upon exercise of the Rights or
Shares.

         2.2.  Representations  and  Warranties  of VEBA.  VEBA  represents  and
warrants to the Company  that, as of the date of this  Agreement,  and covenants
and agrees that as of the Closing  Date,  it will be deemed to have  represented
and warranted as of such date, that:

              (a) VEBA is a corporation duly organized and validly existing,  is
in good standing under the laws of the State of Delaware.

              (b) The execution and delivery of, and the  performance by VEBA of
its obligations  under, this Agreement have been duly and validly  authorized by
VEBA,  and this  Agreement  has been duly  executed  and  delivered  by VEBA and
constitutes the valid and legally binding agreement of VEBA, enforceable against
VEBA  in  accordance  with  its  terms,   except  as  rights  to  indemnity  and
contribution  hereunder may be limited by federal or state  securities  laws and
subject to limitations on enforcement under applicable  bankruptcy,  insolvency,
liquidation, fraudulent conveyance, reorganization, moratorium and other similar
laws affecting  creditors' rights generally and to general equitable  principles
(whether considered in a proceeding in equity or at law).

              (c) The execution, delivery and performance of this Agreement, the
consummation of the transactions herein contemplated and the compliance with the
terms this  Agreement will not conflict with or result in a breach of any of the
terms or provisions of, or constitute a default under, or give rise to rights of
termination  under,  any deed of trust,  lease,  sublease,  the  certificate  or
articles of  incorporation  or by-laws of VEBA, or any indenture,  mortgage,  or
other  agreement or  instrument to which VEBA is a party or by which VEBA or its
property is bound, or any applicable law, rule, regulation,  judgment,  order or
decree of any government,  governmental  instrumentality  or court,  domestic or
foreign,  having  jurisdiction  over  VEBA  or any of its  subsidiaries,  or the
properties or operations of any of them,  except for any such conflict,  breach,
default,  or  right  of  termination,  as  would  not,  individually  or in  the
aggregate,  be reasonably likely to prevent VEBA from performing its obligations
hereunder.

              (d) The VEBA  Information  as  reflected  in or  omitted  from the
Registration  Statement  and the  Prospectus  does not and will not  include any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements  therein,  in light of the
circumstances in which they were made, not misleading.  "VEBA Information" means
the following information: (i) the identity, business, management and activities
of VEBA AG and its  affiliates  (other than the  Company and its  subsidiaries),
(ii) the plans of VEBA AG or its  affiliates  (other  than the  Company  and its
subsidiaries)  relating  to the  Company  or shares of Common  Stock,  (iii) the
number of shares of Common Stock  beneficially owned by VEBA or which VEBA has a
right to acquire,  (iv)  information  regarding the ownership or control of VEBA
common  stock by VEBA AG and its  affiliates  (other  than the  Company  and its
subsidiaries),  (v) statements regarding the commitment or intentions of VEBA AG
and affiliates (other than the Company and its subsidiaries) with respect to the
Company,  and (vi) the plans of VEBA AG or its  affiliates  with  respect to the
inclusion of the Company in the consolidated  federal income tax return filed by
VEBA ("VEBA Consolidated  Federal Income Tax Return") and related matters in the
event that the ownership of Common Stock by VEBA AG or its  affiliates  entitles
any such entity to include the Company in the VEBA  Consolidated  Federal Income
Tax Return.

              (e)  Neither  VEBA AG nor VEBA has any  reason to  believe  that a
breach of any  representation or warranty  contained herein has occurred or that
the Registration Statement or Prospectus (if amended or supplemented, as amended
or  supplemented)  contains any untrue  statement of a material fact or omits to
state any material fact  required to be stated  therein or necessary to make the
statements therein not misleading.

              (f) Neither VEBA nor its affiliates (other than the Company or its
subsidiaries) has employed any investment  banker,  broker or finder or incurred
any liability for any brokerage fees, commissions or finder's fees in connection
with the transactions contemplated by this Agreement.

              (g) VEBA has as of the date of this Agreement,  and will have upon
exercise of its  Rights,  the  financial  wherewithal  to honor its  commitments
hereunder.

              (h) VEBA  understands  that the offering and sale of the Shares is
intended to be exempt from  registration  under the  Securities  Act of 1933, as
amended (the "Securities Act"),  pursuant to Section 4(2) of the Securities Act.
VEBA is not acquiring the Shares as a result of (i) any advertisement,  article,
notice or other communication  published in any newspaper,  magazine, or similar
media or broadcast  over  television or radio or (ii) any seminar  meeting whose
attendees had been invited as a result of,  subsequent to, or pursuant to any of
the foregoing.

              (i)  VEBA  (or  any  permitted  assignee  under  Section  6.4)  is
acquiring  the  Shares  solely  by and for its own  account  as  principal,  for
investment  purposes  only,  and not for the account of any other person and not
with a view to, or for, distribution, assignment, fractionalization or resale or
distribution to others in whole or in part in violation of the Securities Act.

              (j) VEBA is an accredited investor under the Securities Act.

              (k) VEBA  hereby  waives its right under the  Registration  Rights
Agreement between VEBA (as successor to Huls Corporation) and the Company, dated
July 12, 1995, (the "Registration Rights Agreement") to have its existing shares
of Common Stock included in the  Registration  Statement and thereby  registered
under the Securities Act in connection therewith.

              (l)  VEBA  acknowledges  that  the  Company  is  relying  upon the
representations and warranties  contained herein in determining to make the sale
of the Shares, and VEBA consents to such reliance.


                                   ARTICLE III
                                 RIGHTS OFFERING

         3.1. Subscription Offer. The Company will use its reasonable efforts to
distribute at no charge to holders of its Common Stock of record as of the close
of business on a date (the "Record Date")  established by the special  committee
of the Board of  Directors  designated  to take all board  action in  connection
with,  and to  consider  and/or  approve,  the  Rights  Offering  (the  "Special
Committee"),  a specified number or fraction of transferable subscription rights
(each, a "Right") for every share of Common Stock held on the Record Date,  with
each such Right  entitling  the  holder  thereof to  subscribe  for (the  "Basic
Subscription  Privilege")  and to purchase  one share of Common  Stock,  for the
Subscription  Price.  The number of Rights  distributed to each holder of Common
Stock  will be rounded  up to the  nearest  whole  number.  Notwithstanding  the
foregoing,  VEBA agrees that the Company will not  distribute any Rights to VEBA
or to any permitted  transferee of its shares of Common Stock. If VEBA transfers
any shares of Common  Stock prior to the Record  Date,  VEBA will cause any such
transferee to agree that it will not be entitled to any  distribution  of Rights
from the Company in the Rights Offering with respect to such shares.  The Rights
will expire as provided in the Prospectus, unless extended as described therein.
Each Right also carries with it the right to  subscribe  (the  "Oversubscription
Privilege")  at the  Subscription  Price  for an  unlimited  number of shares of
Common Stock that are not otherwise  purchased through the exercise of the Basic
Subscription  Privilege,   subject  to  reduction  by  the  Company  in  certain
circumstances. If an insufficient number of shares of Common Stock are available
to satisfy fully all subscriptions  pursuant to the Oversubscription  Privilege,
then the available  shares of Common Stock will be prorated  among those persons
who subscribe pursuant to the Oversubscription Privilege (other than VEBA or its
permitted  transferee),  based on the respective  numbers of Rights exercised by
such persons  pursuant to the Basic  Subscription  Privilege.  The Company shall
allocate Shares to VEBA as provided in Section 1.2. The Rights will be evidenced
by  the  Rights  Certificates.   Notwithstanding   anything  contained  in  this
Agreement,  in no  event  shall  the  Rights  Offering  result  in VEBA  and its
affiliates  (within the meaning of the Securities  Act) in the aggregate  owning
less than 52% of the  issued  and  outstanding  shares  of  Common  Stock of the
Company  (excluding shares issuable  pursuant to the Company's  employee benefit
plans), immediately after consummation of the Rights Offering.

         3.2. Restricted Nature of Shares. VEBA acknowledges that the Shares, in
its hands, will be restricted  securities under the Securities Act which may not
be  sold or  offered  for  sale  in the  absence  of an  effective  registration
statement  as to such Shares under the  Securities  Act or an opinion of counsel
satisfactory to the Company that such registration is not required.  VEBA agrees
it will not  transfer,  by way of gift or  otherwise,  or sell the Shares or any
part thereof,  unless such Shares have been registered  under the Securities Act
and any  applicable  state  securities  laws  or it  first  obtains,  at its own
expense,  if  requested  by  the  Company,  an  opinion  of  counsel  reasonably
satisfactory  to the  Company  that the  transfer of such Shares may be effected
without   registration  under  the  Securities  Act  and  any  applicable  state
securities laws. VEBA acknowledges  that the certificates  evidencing the Shares
will contain a legend to such effect.


                                   ARTICLE IV
                            COVENANTS OF THE PARTIES

         4.1  Covenants  of  the  Company.  In  further   consideration  of  the
agreements of VEBA herein contained, the Company covenants as follows:

              (a) Effectiveness of Registration Statement.  The Company will use
its reasonable  efforts to cause the Registration  Statement to become effective
and will advise VEBA  promptly  and, if  requested  by VEBA,  will  confirm such
advice in writing (i) when the  Registration  Statement,  or any  post-effective
amendment to the Registration  Statement,  shall have become  effective,  or any
supplement to the  Prospectus or any amended  Prospectus  shall have been filed,
(ii) of the necessity of amending or supplementing the Prospectus or any amended
Prospectus in order to then meet the  requirements of the Securities Act and the
reasons why such  amendment or supplement is necessary,  (iii) of any request of
the Commission for amendment or supplementing  of the Registration  Statement or
Prospectus  or for  additional  information,  and  (iv) of the  issuance  by the
Commission of any stop order  suspending the  effectiveness  of the Registration
Statement or of any order preventing or suspending the use of any preliminary or
amended  preliminary  prospectus or the Prospectus,  or of the suspension of the
qualification of the Securities for offering or sale in any jurisdiction,  or of
the institution of any  proceedings  for any of such purposes.  The Company will
use its reasonable  efforts to prevent the issuance of any such stop order or of
any order  preventing or  suspending  such use and to obtain as soon as possible
the lifting thereof, if issued.

              (b)  Amendment  of  Registration  Statement  and  Prospectus.  The
Company will not file any  amendment to the  Registration  Statement or make any
amendment or supplement to the Prospectus  (including the filing of any document
which,  upon filing,  becomes an Incorporated  Document) of which VEBA shall not
previously  have been  advised or to which VEBA shall  reasonably  object  after
being so advised.

              (c) Copies.  The Company will deliver to VEBA,  without charge, as
soon as the Registration Statement shall have become effective, 10 copies of the
Prospectus  (as  supplemented  or amended,  if the  Company  shall have made any
supplements or amendments to the Prospectus).

              (d)  Authorized  Shares.  The Company  will  maintain at all times
sufficient reserved, authorized but unissued shares of Common Stock for issuance
upon exercise of the Rights.

              (e)  Amendment  or  Termination  of Rights  Offering.  The Company
reserves  the right to amend the terms and  conditions  of the Rights  Offering;
provided,  however,  the  Company may not change the  Subscription  Price or the
number of shares of Common  Stock  issuable  in the Rights  Offering or take any
other action which would  materially  adversely  affect VEBA's rights  hereunder
without  the written  consent of VEBA.  The  Company  may  terminate  the Rights
Offering at any time only if (i) it does not receive  the  Fairness  Opinion (as
defined  in  Section  5.1(f))  or (ii) the  special  committee  of the  board of
directors of the Company  delegated  authority to take action in connection with
the Rights  Offering  determines  in good faith,  after  receiving the advice of
outside  counsel,  that  proceeding  with the Rights  Offering would result in a
breach of its fiduciary  duties to the Company's  stockholders  under applicable
law.

              (f) Rule 158.  The Company  will make  generally  available to its
security holders an earnings  statement,  which need not be audited,  covering a
twelve-month  period  commencing  after the effective  date of the  Registration
Statement (as defined in Rule 158 under the Securities Act) and ending not later
than 15 months thereafter,  as soon as practicable after the end of such period,
which  earnings  statement  shall satisfy the provisions of Section 11(a) of the
Securities Act.

              (g) Expenses.  In the event of a termination  of this Agreement or
if the Rights  Offering  is not  otherwise  consummated  (other  than solely (i)
because of a breach by VEBA of its  representations,  warranties,  covenants  or
agreements hereunder or (ii) pursuant to Section 6.8(c) of this Agreement),  the
Company  agrees  to  reimburse  VEBA  and  its  affiliates  (as  defined  in the
Securities Act), other than the Company and its subsidiaries, for all reasonable
out-of-pocket  expenses  (including  reasonable  fees and  expenses  of counsel)
incurred by VEBA and such affiliates in connection with the Rights Offering (but
excluding expenses attributable to the Private Placement),  provided the Company
receives  reasonable  supporting  documentation  of such expenses.  

         (h) No Price  Stabilization or Manipulation.  The Company (a) will not,
except as disclosed in the Registration Statement, sell, bid for or purchase, or
pay anyone any  compensation  for soliciting  purchases of, the Company's Common
Stock or the Rights and (b) will not, until the later of the Expiration  Date or
the completion of the distribution (within the meaning of Regulation M under the
Exchange Act) of the shares of Common Stock, sell, bid for or purchase, apply or
agree to pay to any person any compensation  for soliciting  another to purchase
any  other  securities  of the  Company  (except  for  the  solicitation  of the
exercises of Rights pursuant to this  Agreement).  The foregoing shall not apply
to the offer, sale,  agreement to sell or delivery with respect to (1) shares of
Common Stock offered and sold upon  exercise of the Rights,  as described in the
Prospectus,  or (2) any shares of Common  Stock sold  pursuant  to any  employee
benefit plan.

         4.2 Covenants of VEBA. In further  consideration  of the  agreements of
the Company herein contained, VEBA covenants as follows:

              (a) VEBA has not taken and will not take,  directly or indirectly,
any action designed to or which might be reasonably  expected to cause or result
in stabilization or manipulation of the price of the Company's Common Stock, and
VEBA  has no  reason  to  believe  that any such  action  has been  taken by its
affiliates other than the Company and its subsidiaries,  and will not permit any
such affiliate to take such action.

              (b) When the Registration  Statement becomes  effective,  the VEBA
Information (as defined in Section 2.2(d)) will not contain any untrue statement
of a material  fact or omit to state any  material  fact  required  to be stated
therein  or  necessary  to  make  the   statements   therein  in  light  of  the
circumstances in which they were made not misleading.

              (c) VEBA will not take any  action  to  prevent  the  Registration
Statement or any post-effective amendment thereto from becoming effective.

              (d) VEBA will use its  reasonable  efforts  to do or  perform  all
things  required to be done or performed by VEBA or its  affiliates  (other than
the  Company  and its  subsidiaries)  prior to the  Closing  Date to satisfy all
conditions  precedent  to  the  consummation  of the  transactions  contemplated
hereby.

              (e) Until  the  Expiration  Date,  VEBA will  advise  the  Company
promptly,  and if requested by the Company, will promptly confirm such advice in
writing,  of (A)  any  change  in (i)  the  VEBA  Information,  or  (ii)  VEBA's
intentions with respect to transactions and  relationships  among VEBA AG or its
affiliates (other than the Company and its  subsidiaries),  on the one hand, and
the Company or its  affiliates,  on the other hand,  or (B) any new  information
relating to (i) VEBA  Information  or (ii)  VEBA's  intentions  with  respect to
transactions and relationships among VEBA AG or its affiliates, on the one hand,
and  the  Company  or its  affiliates,  on  the  other  hand,  that  causes  the
Registration  Statement or the Prospectus (as then amended or  supplemented,  if
amended or supplemented) to contain an untrue statement of material fact or omit
to state a material fact necessary in order to make the statements  therein,  in
light of the circumstances in which they are made, not misleading.

                        CONDITIONS TO OBLIGATIONS OF VEBA

         5.1.  Conditions  to  VEBA's  Obligations.  The  obligation  of VEBA to
purchase the Shares  hereunder is subject to the  satisfaction  of the following
conditions on or prior to the Expiration Date:

              (a) VEBA shall have received on the  Expiration  Date, the opinion
of Bryan  Cave  LLP,  counsel  for the  Company,  addressed  to VEBA,  dated the
Expiration Date and substantially to the effect that:

                   (i) The Company is a corporation  validly  existing and is in
    good standing  under the laws of the State of Delaware and has all requisite
    corporate  power and  authority to carry on its business as described in the
    Registration Statement and the Prospectus;

                   (ii) The shares of Common Stock issuable upon exercise of the
    Rights  and  issuable  to VEBA  pursuant  to this  Agreement  have been duly
    authorized  and,  when  issued and  delivered  against  payment  therefor in
    accordance  with the terms of the Rights  Offering or this  Agreement as the
    case may be, will be (A) validly issued,  fully paid and  nonassessable  and
    (B) free of any  preemptive  or similar  rights that entitle or will entitle
    any person to acquire any shares of Common Stock upon the  issuance  thereof
    by the Company by operation of the certificate of incorporation or bylaws of
    the Company, or to the knowledge of such counsel, pursuant to any agreement;

                   (iii) None of the  issuance  and sale of the shares of Common
    Stock upon exercise of the Rights, the execution, delivery or performance of
    this  Agreement  by the  Company,  the  consummation  by the  Company of the
    transactions contemplated hereby (including the issuance and sale to VEBA of
    the Shares) nor the  compliance  by the Company with the terms of the Rights
    and this Agreement  constitutes or will constitute a violation or breach of,
    or a  default  under,  the  certificate  of  incorporation  or bylaws of the
    Company  or any  Material  Agreement,  or will  result  in the  creation  or
    imposition  of any lien,  charge or  encumbrance  pursuant  to any  Material
    Agreement  upon  any  property  or  assets  of  the  Company  or  any of its
    subsidiaries,  nor will any  such  action  result  in any  violation  of the
    Delaware  General  Corporation  Law (the  "DGCL"),  any existing  Federal or
    Missouri law,  regulation,  ruling (assuming  compliance with all applicable
    state  securities  and Blue  Sky  laws)  recognized  by such  counsel  to be
    applicable  to, or any judgment,  injunction,  order or decree known to such
    counsel of any Federal or Missouri  court to be  applicable  to the Company,
    its subsidiaries or any of their respective properties  (provided,  the term
    "Material  Agreement"  shall mean any agreement,  indenture,  lease or other
    instrument  that is both (i) an exhibit to the  Registration  Statement  and
    (ii) an agreement, indenture, lease or other instrument to which the Company
    or any of its subsidiaries is a party or by which any of their properties or
    assets are bound);

                   (iv)  Such  counsel  has  been  advised  by the  Staff of the
    Commission that the  Registration  Statement has become  effective under the
    Securities  Act  and,  to the  knowledge  of such  counsel,  no  stop  order
    suspending the  effectiveness of the Registration  Statement has been issued
    and no proceedings  for that purpose are pending before or threatened by the
    Commission;  and any  required  filing of the  Prospectus  pursuant  to Rule
    424(b) has been made in accordance with Rule 424(b);

                   (v) (A) The Company has the corporate  power and authority to
    enter  into this  Agreement  and to issue,  sell and  deliver  the shares of
    Common Stock  issuable  upon  exercise of the Rights and to VEBA pursuant to
    this  Agreement,  (B) the  Rights  Offering  has  been  duly  authorized  by
    corporate action, and (C) this Agreement has been duly authorized,  executed
    and delivered by the Company;

                   (vi) No consent,  approval,  authorization or other order of,
    or registration  or filing with, any Federal or Missouri  court,  regulatory
    body,  administrative agency or other governmental body, agency, or official
    is required to be  obtained  by the  Company  (except as have been  obtained
    under the  Securities  Act and the  Exchange  Act or such as may be required
    under state  securities or Blue Sky laws governing the sale and distribution
    of the shares of Common Stock) for the valid issuance and sale of the shares
    of  Common  Stock  issuable  upon  exercise  of the  Rights  or to  VEBA  in
    accordance with this Agreement; and

                   (vii) Each of the Registration Statement, as of its effective
    date, and the Prospectus,  as of its date (including  Incorporated Documents
    and  except  for the  financial  statements  and the notes  thereto  and the
    schedules and other  financial and  statistical  data or schedules  included
    therein or omitted therefrom,  as to which such counsel need not express any
    opinion),  comply as to form in all material  respects with the requirements
    of the Securities Act.

In addition to the matters set forth above,  such  opinion  shall also contain a
statement to the effect that,  although  counsel has not  undertaken,  except as
otherwise indicated in their opinion, to determine  independently,  and does not
assume any responsibility for, the accuracy or completeness of the statements in
the Registration Statement,  such counsel has participated in the preparation of
the Registration  Statement and the Prospectus,  including review and discussion
of the contents  thereof  (including a review and  discussion of the contents of
all  Incorporated  Documents),  and  nothing has come to the  attention  of such
counsel  that has  caused  it to  believe  (i) that the  Registration  Statement
(including the Incorporated  Documents),  and any amendment thereto, at the time
it became  effective  (excluding  any VEBA  Information),  contained  any untrue
statement of a material  fact or omitted to state a material fact required to be
stated  therein or necessary to make the  statements  therein not  misleading or
(ii)  that  the  Prospectus  (including  the  Incorporated  Documents),  or  any
amendment or supplement to the Prospectus,  as of its respective date, and as of
the Closing Date (excluding any VEBA Information) contained any untrue statement
of a material  fact or omitted to state a material  fact  necessary  in order to
make the statements  therein, in the light of the circumstances under which they
were made,  not  misleading  (it being  understood  that such  counsel  need not
express any  opinion  with  respect to the  financial  statements  and the notes
thereto and the schedules and other financial and statistical  data or schedules
included or  incorporated  by  reference  in the  Registration  Statement or the
Prospectus or omitted therefrom).

         With  respect to specific  matters with respect to which Bryan Cave LLP
does not  represent  the Company,  the  foregoing  statement may be delivered by
other counsel that  represents  the Company with respect to such  matters,  such
counsel to be reasonably acceptable to VEBA.

         In  rendering  the  foregoing  opinion,  such  counsel may rely,  as to
matters  involving  laws of any  jurisdiction  other than Missouri or the United
States or the DGCL, upon opinions  addressed to VEBA of other counsel reasonably
acceptable  to VEBA,  provided  that insofar as any such opinion  relates to the
DGCL,  such  opinion may be  delivered  by  Richards,  Layton & Finger,  P.A. In
addition,   the  foregoing  opinion  may  contain   customary   assumptions  and
qualifications.

              (b) VEBA shall have  received a letter  addressed  to it and dated
the  Expiration  Date from KPMG Peat Marwick LLP  independent  certified  public
accountants to the Company, in form and substance reasonably  acceptable to VEBA
and set forth in SAS 72 and customary for a firm commitment underwriting.

              (c)  (i)  No  stop  order  suspending  the  effectiveness  of  the
Registration  Statement  shall  have been  issued  and no  proceedings  for that
purpose  shall  have been  taken;  (ii) there  shall not have been any  material
change in the  capital  stock of the Company  nor any  material  increase in the
short-term  or  long-term  debt  of  the  Company  and  its  subsidiaries  on  a
consolidated basis (other than in the ordinary course of business or pursuant to
existing  agreements  with  VEBA AG or its  affiliates)  from  the  date of this
Agreement; (iii) there shall not have been, since the date of this Agreement any
material  adverse  change  in the  condition  (financial  or  other),  business,
prospects, properties, net worth or results of operations of the Company and its
subsidiaries  taken as a whole; (iv) the Company and its subsidiaries  shall not
have any liabilities or obligations, direct or contingent (whether or not in the
ordinary course of business,  except for any liabilities or obligations,  direct
or contingent,  with VEBA and its affiliates),  that are material to the Company
and its  subsidiaries,  taken as a whole,  other than those in  existence on the
date  hereof;  and (v) all the  representations  and  warranties  of the Company
contained in this Agreement  shall be true and correct in all material  respects
on and as of the Expiration  Date as if made on and as of the  Expiration  Date;
and (vi) VEBA shall have received a certificate,  dated the Expiration  Date and
signed by the chief executive  officer and the chief financial officer (or other
reasonably  acceptable officers) in the name and on behalf of the Company to the
effect set forth in this Section 5.1(c).

              (d) The Shares and Rights shall have been  approved for listing on
the New York Stock Exchange,  subject to official  notice of issuance,  prior to
the Expiration Date.

              (e) The  Registration  Rights Agreement shall have been amended to
include all Shares purchased by VEBA, VEBA AG or any subsidiaries of VEBA AG and
any other shares of Common Stock  acquired or purchased by VEBA,  VEBA AG or any
subsidiaries of VEBA AG after the date hereof as Registrable  Stock  thereunder,
such amendment to be effective as of the Closing Date.

              (f)  VEBA  shall  have  received  confirmation  that  the  Company
received prior to commencement of the Rights Offering a fairness  opinion from a
financial  advisor  substantially to the effect that (i) the VEBA Purchase Price
to be paid to the Company by VEBA is fair to the  Company  and its  stockholders
(other than VEBA) from a financial  point of view as of the date  thereof,  (ii)
the financial  terms and conditions of the Rights  Offering are consistent  with
those of rights offerings by public companies  reviewed and deemed comparable to
the Rights Offering by such financial  advisor and (iii) the Subscription  Price
is fair to the Company and its  stockholders  (other than VEBA) from a financial
point of view as of the date thereof (the "Fairness Opinion").


                                   ARTICLE VI
                            MISCELLANEOUS PROVISIONS

         6.1.  Indemnification  and  Contribution.  (a) The  Company  agrees  to
indemnify and hold harmless VEBA, its officers, directors,  employees and agents
and each person, if any, who controls VEBA (collectively,  the "VEBA Indemnified
Persons")  within the  meaning of  Section 15 of the  Securities  Act or Section
20(a) of the Exchange Act from and against any and all losses, claims,  damages,
liabilities and reasonable expenses  (including  reasonable legal fees and costs
of  investigation)  (collectively  "Losses")  arising  out of or based  upon any
untrue statement or alleged untrue statement of a material fact contained in the
Registration  Statement or the  Prospectus  or in any  amendment  or  supplement
thereto,  or arising out of or based upon any  omission  or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the  statements  therein not  misleading,  but only with respect to  information
other than VEBA  Information,  except that the Company shall have no obligations
under this Section 6.1 for any untrue  statement or omission to state a material
fact contained in a preliminary  prospectus that was corrected in the Prospectus
(as amended or  supplemented).  The foregoing  indemnity  agreement  shall be in
addition to any liability which the Company may otherwise have.  Notwithstanding
the foregoing,  to the extent (A) the compliance  certificate delivered pursuant
to Section 5.1(c)(vi)  contains any exceptions and (B) VEBA nevertheless  elects
to consummate the transaction  contemplated  under this  Agreement,  the Company
shall not be obligated to  indemnify,  hold harmless or contribute to the Losses
of any VEBA Indemnified  Party (or reimburse its related  expenses) with respect
to such  exceptions  under this Section 6.1 and VEBA shall not have any claim or
remedy under this Agreement with respect to such excepted matters, except (x) to
the extent such Losses  result from an inaccuracy  contained in such  compliance
certificate  and (y) to the extent  such Losses  result from an action,  suit or
proceeding  commenced by a person other than a VEBA  Indemnified  Person arising
out of or based  upon any untrue  statement  or alleged  untrue  statement  of a
material fact  contained in the  Registration  Statement or the Prospectus or in
any  amendment  or  supplement  thereto,  or  arising  out of or based  upon any
omission or alleged  omission to state  therein a material  fact  required to be
stated therein or necessary to make the statements  therein not misleading,  but
only with respect to information  other than VEBA  Information;  except that the
Company  shall  have no  obligations  under  this  Section  6.1  for any  untrue
statement  or  omission  to state a material  fact  contained  in a  preliminary
prospectus that was corrected in the Prospectus (as amended or supplemented).

              (b) VEBA agrees to indemnify  and hold  harmless the Company,  its
officers,  directors,  employees  and agents,  and any person who  controls  the
Company  within the meaning of Section 15 of the Securities Act or Section 20(a)
of the  Exchange  Act, to the same extent as the  foregoing  indemnity  from the
Company to VEBA, but only with respect to the VEBA Information  except that VEBA
shall have no  obligations  under this  Section 6.2 for any untrue  statement or
omission to state a material fact with regard to the VEBA Information  contained
in a preliminary  prospectus that was corrected in the Prospectus (as amended or
supplemented).  The foregoing  indemnity  agreement  shall be in addition to any
liability which VEBA may otherwise have.

              (c) If the  indemnification  provided  for in this  Section 6.1 is
unavailable  to an  indemnified  party  under  paragraphs  (a) or (b)  hereof in
respect of any Losses referred to therein,  then an indemnifying  party, in lieu
of indemnifying such indemnified  party,  shall contribute to the amount paid or
payable  by such  indemnified  party  as a  result  of such  Losses  (i) in such
proportion as is  appropriate to reflect the relative  benefits  received by the
Company on the one hand and VEBA on the other hand from the Rights  Offering and
the Private  Placement taken as a whole,  or (ii) if the allocation  provided by
clause (i) above is not  permitted by applicable  law, in such  proportion as is
appropriate to reflect not only the relative  benefits referred to in clause (i)
above but also the relative fault of the Company on the one hand and VEBA on the
other hand in connection  with the statements or omissions that resulted in such
Losses, as well as any other relevant equitable considerations.

              (d) The procedures  set forth in Section 8(c) of the  Registration
Rights Agreement dated July 12, 1995 between the Company and Huls Corporation (a
predecessor to VEBA) shall govern any  indemnification  pursuant to this Section
6.1.

         6.2. Notice. All notices,  requests,  demands, and other communications
required  or  permitted  under this  Agreement  shall be in writing and shall be

thereof is deposited,  postage  prepaid,  certified or registered  mail,  return

                      Attention:  Helene F. Hennelly
                                  Corporate Vice President,

                      Fax:  (314) 279-5158

         6.3. Entire Agreement. This Agreement, together with the Stock Purchase
Agreement, embodies the entire agreement and understanding of the parties hereto
with  respect  to the  subject  matter  hereof,  and  supersedes  all  prior and
contemporaneous agreements and understandings relative to such subject matter.

         6.4.  Assignment;  Binding  Agreement.  This  Agreement and the various
rights and  obligations  arising  hereunder shall inure to the benefit of and be
binding upon VEBA, its successors,  and permitted  assigns and the Company,  its
successors, and permitted assigns. Neither this Agreement nor any of the rights,
interests, or obligations hereunder shall be transferred, delegated, or assigned
(by operation of law or otherwise) by either of the parties  hereto  without the
prior written consent of the other party,  except that VEBA shall have the right
to transfer  and assign its rights  hereunder  to purchase  Common Stock and any
other rights or benefits afforded to it by this Agreement to (x) VEBA AG or VEBA
Zweite  Verwaltungsgesellschaft  mbH and (y) any other direct or indirect wholly
owned  subsidiary of VEBA AG,  provided that,  only in the case of the foregoing
subclause (y), to the extent  required by law, such right to transfer and assign
shall be subject to the prior  approval  of the  Company's  Board of  Directors,
which  approval shall not be  unreasonably  withheld and, in the case of both of
the  foregoing  sub  clauses  (x)  and  (y),  any  such  transferee   makes  the
representations and warranties  contained in Sections 2.2(h),  2.2(i) and 2.2(j)
and  acknowledges and agrees to the provisions of Section 3.2. Any such transfer
shall not discharge VEBA from its obligations hereunder.

         6.5.   Counterparts;   Expenses.   This   Agreement   may  be  executed
simultaneously  in  multiple  counterparts,  each of which  shall be  deemed  an
original,  but all of which taken  together  shall  constitute  one and the same
instrument.  Except to the extent set forth in Section 4.1(g),  each party shall
bear the fees and expenses  incurred by such party incidental to the preparation
of, and the consummation of the transactions contemplated by, this Agreement.

         6.6.  Headings;   Interpretation.  The  article  and  section  headings
contained in this  Agreement  are inserted  for  convenience  only and shall not
affect in any way the meaning or interpretation of the Agreement. Each reference
in this Agreement to an Article or Section,  unless otherwise  indicated,  shall
mean an  Article or a Section of this  Agreement.  References  herein to "days,"
unless otherwise indicated,  are to consecutive calendar days. Both parties have
participated substantially in the negotiation and drafting of this Agreement and
agree that no ambiguity herein should be construed against the draftsman.

         6.7 Taxes.  In the event  that VEBA and its  affiliates'  ownership  of
Common  Stock  entitles  VEBA to include  the  Company in the VEBA  Consolidated
Federal Income Tax Return,  VEBA and the applicable VEBA affiliates  shall enter
into a tax sharing or affiliation  agreement with the Company.  Such tax sharing
or affiliation  agreement shall provide that the inclusion of the Company in the
VEBA  Consolidated  Federal  Income Tax Return  will not be  detrimental  to the
Company for federal  income tax purposes as compared with the federal income tax
treatment  of the Company had it not been  includible  in the VEBA  Consolidated
Federal Income Tax Return and such tax sharing or affiliation agreement shall be
in form and substance reasonably acceptable to the Company and VEBA.

         6.8. Termination of the Agreement.

              (a) Prior to consummation of the transactions contemplated hereby,
this  Agreement  may be  terminated:  (i) at any time prior to the Closing Date,
upon  termination  of the Rights  Offering by the Company,  in  accordance  with
Section 4.1(e), without further liability or obligation, or (ii) after March 31,
1999, by either party hereto,  without further  liability or obligation,  if (x)
such party is not in breach or violation  hereof and (y) the  conditions to such
party's obligations have not then been satisfied.

              (b) Either  party may  terminate  this  Agreement  if more than an
aggregate  of 150 million  shares of Common Stock would be required to be issued
in  connection  with,  or the Company would receive more than $200 million from,
the  consummation  of the  purchase  and sale of Common  Stock  pursuant to this
Agreement, the Stock Purchase Agreement and the Rights Offering.

              (c) This  Agreement  shall be  subject  to  termination  in VEBA's
discretion after consultation with the Company, without liability on the part of
VEBA to the  Company,  by notice to the  Company,  if on or 20 days prior to the
Expiration  Date,  (i)  trading in  securities  generally  on the New York Stock
Exchange,  American Stock Exchange or the Nasdaq National Market is suspended or
materially  limited,  (ii) a general moratorium on commercial banking activities
in New York  shall  have been  declared  by  either  federal  or New York  State
authorities,  or (iii) there shall have  occurred any outbreak or  escalation of
hostilities  or other  international  or domestic  calamity,  crisis or material
adverse  change in  political,  financial  or economic  conditions,  which has a
materially adverse impact on the ability of the Company to distribute the shares
of Common Stock in the Rights Offering.

              (d) The  provisions of Section 4.1(g) and Article VI shall survive
any termination of this Agreement.

         6.9.  Governing Law. This Agreement  shall in all respects be construed
in  accordance  with and  governed by the  substantive  laws of the State of New
York, without reference to its choice of law rules,  except that matters subject
to the General Corporation Law of Delaware shall be governed by such laws.


         IN  WITNESS  WHEREOF,  each  of the  parties  hereto  has  caused  this
Agreement to be executed as of the date first above written.
