                                   ABOUT DOW

   We are a global science and technology based company that develops and
manufactures a portfolio of chemicals, plastics and agricultural products and
services for customers in 162 countries around the world. With annual sales of
approximately $19 billion, we conduct operations through 14 global businesses
employing approximately 39,200 people. We have 123 manufacturing sites in 32
countries and supply more than 2,400 products. We were incorporated in 1947
under Delaware law and are the successor to a Michigan corporation, of the same
name, organized in 1897. Our principal executive offices are located at 2030
Dow Center, Midland, Michigan 48674, and our telephone number is 517-636-1000.

                              RECENT DEVELOPMENTS

   On January 26, 2001, we reported our financial results for the year ended
December 31, 2000. Net sales increased 16% to $21,870 million in 2000 from
$18,929 million in 1999. Net income increased 14% to $1,513 million in 2000
from $1,326 million in 1999. At December 31, 2000, we had long-term debt
(excluding current maturities) of $4,865 million and net stockholders equity of
$9,186 million.

   On August 4, 1999, we and Union Carbide Corporation announced a definitive
merger agreement for a tax-free, stock-for-stock transaction. Under the
agreement, Union Carbide stockholders will receive 0.537 of a share of our
stock for each share of Union Carbide stock they own. Based upon our closing
price of $124 11/16 on August 3, 1999, the transaction was valued at $66.96 per
Union Carbide share, or $11.6 billion in the aggregate, including the
assumption of $2.3 billion of net debt. According to the agreement, the merger
is subject to certain conditions including approval by Union Carbide
stockholders and review by antitrust regulatory authorities in the United
States, Europe and Canada. Union Carbide stockholders approved the merger on
December 1, 1999. On May 3, 2000, the European Commission approved the merger
subject to certain conditions. On February 5, 2001, the Federal Trade
Commission approved the merger subject to certain conditions. The merger is
expected to close shortly. The transaction is expected to be accounted for as a
pooling-of-interests.

                                USE OF PROCEEDS

   The net proceeds from the sale of Notes is expected to be approximately
$492,400,000. We will use the net proceeds for general corporate purposes,
including repayment of short-term debt.

only, in denominations of $1,000 and integral multiples of that amount.

   We may, without the consent of the holders of Notes, issue additional notes
having the same ranking and the same interest rate, maturity and other terms as
the Notes. Any additional debt securities having such similar terms, together
with the Notes, will constitute a single series of debt securities under the
indenture. In the event that we issue additional Notes, we will make a new
application to list such Notes on the Luxembourg Stock Exchange.

Interest

   We will pay interest on the Notes at a rate of 6 1/8% per annum semiannually
in arrears on February 1 and August 1 of each year, commencing August 1, 2001,
to the persons in whose names the Notes are registered at the close of business
on January 15 or July 15, as the case may be (whether or not a Business Day),
immediately preceding the relevant interest payment date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

   If any interest payment date falls on a day that is not a Business Day, the
interest payment will be postponed to the next day that is a Business Day, and
no interest on such payment will accrue for the period from and after such
interest payment date. If the maturity date of the Notes falls on a day that is
not a Business Day, the payment of interest and principal may be made on the
next succeeding Business Day, and no interest on such payment will accrue for
the period from and after the maturity date. Interest payments for the Notes
will include accrued interest from and including the date of issue or from and
including the last date in respect of which interest has been paid, as the case
may be, to, but excluding, the interest payment date or the date of maturity,
as the case may be.

   As used in this prospectus supplement, "Business Day" means any day, other
than a Saturday or Sunday, that is neither a legal holiday nor a day on which
banking institutions are authorized or required by law or regulation to close
in The City of New York.

   We may not redeem the Notes prior to maturity except as described below
under "--Redemption for Tax Reasons."

Book-entry, Delivery and Form

   The Notes will be issued in the form of one or more fully registered global
notes which will be deposited with, or on behalf of, DTC and registered in the
name of the Cede & Co., DTC's nominee. Beneficial interests in the global Notes
will be represented through book-entry accounts of financial institutions
acting on behalf of beneficial owners as direct and indirect participants in
DTC. Investors may elect to hold interests in the global Notes through DTC,
Clearstream Banking, societe anonyme, Luxembourg ("Clearstream"), or Euroclear
Bank

                                      S-7


S.A./NV, as operator of the Euroclear System ("Euroclear") if they are
participants of such systems, or indirectly through organizations which are
participants in such systems. Clearstream and Euroclear will hold interests on
behalf of their participants through customers' securities accounts in
Clearstream's and Euroclear's names on the books of their respective
depositaries. Clearstream's and Euroclear's depositaries will hold interests in
customers' securities accounts in the depositaries' names on the books of DTC.
Citibank, N.A. will act as depositary for Clearstream and The Chase Manhattan
Bank will act as depositary for Euroclear (in such capacities, the "U.S.
Depositaries"). Except as set forth below, the global Notes may be transferred,
in whole and not in part, only to another nominee of DTC or to a successor of
DTC or its nominee.

   DTC has advised us that DTC is a limited-purpose trust company organized
under the New York Banking Law, a "banking organization" within the meaning of
the New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. DTC holds securities deposited
with it by its participants and facilitates the settlement of transactions
among its participants in those securities through electronic computerized
book-entry changes in accounts of the participants, thereby eliminating the
need for physical movement of securities certificates. DTC's participants
include securities brokers and dealers, including the Underwriter, banks, trust
companies, clearing corporations and certain other organizations, some of whom,
and/or their representatives, own DTC. Access to the DTC book-entry system is
also available to others, such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a participant,
either directly or indirectly.

   According to DTC, the foregoing information with respect to DTC has been
provided to the financial community for informational purposes only and is not
intended to serve as a representation, warranty or contract modification of any
kind. We make no representation as to the accuracy or completeness of such
information.

   Clearstream has advised that it is incorporated under the laws of the Grand
Duchy of Luxembourg as a professional depositary. Clearstream holds securities
for its participating organizations ("Clearstream participants"). Clearstream
facilitates the clearance and settlement of securities transactions between
Clearstream participants through electronic book-entry changes in accounts of
Clearstream participants, eliminating the need for physical movement of
certificates. Clearstream provides to Clearstream participants, among other
things, services for safekeeping, administration, clearance and settlement of
internationally traded securities and securities lending and borrowing.
Clearstream interfaces with domestic markets in several countries. As a
professional depositary, Clearstream is subject to regulation by the Luxembourg
Commission for the Supervision of the Financial Sector (CSSF). Clearstream
participants are recognized financial institutions around the world, including
underwriters, securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations. Indirect access to Clearstream is
also available to others, such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a Clearstream
participant, either directly or indirectly.

   Distributions, to the extent received by the U.S. Depositary for
Clearstream, with respect to the Notes held beneficially through Clearstream
will be credited to cash accounts of Clearstream participants in accordance
with its rules and procedures.

   Euroclear has advised that it was created in 1968 to hold securities for its
participants ("Euroclear participants") and to clear and settle transactions
between Euroclear participants through simultaneous electronic book-entry
delivery against payment, eliminating the need for physical movement of
certificates and eliminating any risk from lack of simultaneous transfers of
securities and cash. Euroclear provides various other services, including
securities lending and borrowing and interfaces with domestic markets in
several countries. Euroclear is operated by Euroclear Bank S.A./NV (the
"Euroclear Operator"), under contract with Euroclear Clearance Systems S.C., a
Belgian cooperative corporation (the "Cooperative"). All operations are
conducted by the Euroclear Operator, and all Euroclear securities clearance
accounts and Euroclear cash accounts are

                                      S-8


accounts with the Euroclear Operator not the Cooperative. The Cooperative
establishes policy for Euroclear on behalf of Euroclear participants. Euroclear
participants include banks (including central banks), securities brokers and
dealers and other professional financial intermediaries and may include the
underwriters. Indirect access to Euroclear is also available to other firms
that clear through or maintain a custodial relationship with a Euroclear
participant, either directly or indirectly.

   The Euroclear Operator has advised us that it is licensed by the Belgian
Banking and Finance Commission to carry out banking activities on a global
basis. As a Belgian bank, it is regulated and examined by the Belgian Banking
Commission.

   Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian
law (collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities
and cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear participants, and has no record of or relationship with persons
holding through Euroclear participants.

   Distributions, to the extent received by the U.S. Depositary for Euroclear,
with respect to Notes held beneficially through Euroclear will be credited to
the cash accounts of Euroclear participants in accordance with the Terms and
Conditions.

   In the event definitive Notes are issued, we will appoint a paying agent and
transfer agent in Luxembourg (the "Luxembourg Paying and Transfer Agent").
Holders of definitive Notes will be able to receive payments and effect
transfers at the offices of the Luxembourg Paying and Transfer Agent.

   Individual certificates in respect of the Notes will not be issued in
exchange for the global Notes, except in very limited circumstances. If DTC,
Clearstream or Euroclear notifies us that it is unwilling or unable to continue
as a clearing system in connection with the global Notes or DTC ceases to be a
clearing agency registered under the Exchange Act, and a successor clearing
system is not appointed by us within 90 days after receiving that notice from
DTC, Clearstream or Euroclear or upon becoming aware that DTC is no longer so
registered, we will issue or cause to be issued individual certificates in
registered form on registration of transfer of, or in exchange for, book-entry
interests in the Notes represented by such global Notes upon delivery of such
global Notes for cancellation.

   Title to book-entry interests in the global Notes will pass by book-entry
registration of the transfer within the records of DTC, Clearstream or
Euroclear in accordance with their respective procedures. Book-entry interests
in the global Notes may be transferred within DTC in accordance with procedures
established for this purpose by DTC. Book-entry interests in the Notes may be
transferred within Euroclear and within Clearstream and between Euroclear and
Clearstream in accordance with procedures established for these purposes by
Euroclear and Clearstream. A further description of DTC's procedures with
respect to the global Notes is set forth in the prospectus under "Description
of Debt Securities--Global Securities". Transfers of book-entry interests in
the Notes between Euroclear and Clearstream and DTC may be effected in
accordance with procedures established for this purpose by Euroclear,
Clearstream and DTC.

Global Clearance and Settlement Procedures

   Initial settlement for the Notes will be made in immediately available
funds. Secondary market trading between DTC participants will occur in the
ordinary way in accordance with DTC's rules and will be settled in immediately
available funds using the DTC's Same-Day Funds Settlement System. Secondary
market trading between Clearstream participants and/or Euroclear participants
will occur in the ordinary way in accordance with the applicable rules and
operating procedures of Clearstream and Euroclear and will be settled using the
procedures applicable to conventional Eurobonds in immediately available funds.

                                      S-9


   Cross-market transfers between persons holding directly or indirectly
through the DTC on the one hand, and directly or indirectly through
Clearstream or Euroclear participants, on the other, will be effected in the
DTC in accordance with the DTC's rules on behalf of the relevant European
international clearing system by its U.S. Depositary. However, a cross-market
transfer will require delivery of instructions to the relevant European
international clearing system, by the counterparty in such European
international clearing system, in accordance with its rules and procedures and
within its established deadlines (European time). The relevant European
international clearing system will, if the transaction meets its settlement
requirements, deliver instructions to its U.S. Depositary to take action to
effect final settlement on its behalf by delivering or receiving Notes in DTC,
and making or receiving payment in accordance with normal procedures for same-
day funds settlement applicable to DTC. Clearstream participants and Euroclear
participants may not deliver instructions directly to their respective U.S.
Depositaries.

   Because of time-zone differences, credits of Notes received in Clearstream
or Euroclear as a result of a transaction with a DTC participant will be made
during subsequent securities settlement processing and dated the business day
following the DTC settlement date. Credits or any transactions of the type
described above settled during subsequent securities settlement processing
will be reported to the relevant Euroclear or Clearstream participants on the
business day that the processing occurs. Cash received in Clearstream or
Euroclear as a result of sales of Notes by or through a Clearstream
participant or a Euroclear participant to a DTC participant will be received
with value on the DTC settlement date but will be available in the relevant
Clearstream or Euroclear cash account only as of the business day following
settlement in DTC.

   Although DTC, Clearstream and Euroclear have agreed to the foregoing
procedures in order to facilitate transfers of Notes among participants of
DTC, Clearstream and Euroclear, they are under no obligation to perform or
continue to perform these procedures. The foregoing procedures may be changed
or discontinued at any time.

Payment of Additional Amounts

   We will pay to the holder of any of the Notes who is a non-United States
person (as defined below) such additional amounts as may be necessary in order
that every net payment in respect of the principal, premium, if any, or
interest, if any, on the Notes, after deduction or withholding by Dow or any
paying agent for or on account of any present or future tax, assessment or
governmental charge imposed upon or as a result of such payment by the United
States or any political subdivision or taxing authority thereof or therein,
will not be less than the amount provided for in the Notes to be then due and
payable before any such deduction or withholding for or on account of any such
tax, assessment or governmental charge. The foregoing obligation to pay such
additional amounts shall not apply to:

     (a) any tax, assessment or other governmental charge which would not
  have been so imposed but for:

     . the existence of any present or former connection between such
       holder (or a fiduciary, settlor, beneficiary, member or shareholder
       of, or holder of a power over, such holder, if such holder is an
       estate, trust, partnership or corporation) and the United States,
       including, without limitation, such holder (or such fiduciary,
       settlor, beneficiary, member, shareholder of, or holder of a power)
       being or having been a citizen or resident or treated as a resident
       thereof or being or having been engaged in a trade or business
       therein or being or having been present therein or having or having
       had a permanent establishment therein, or

     . such holder's present or former status as a personal holding company
       or foreign personal holding company or controlled foreign
       corporation for United States federal income tax purposes or
       corporation which accumulates earnings to avoid United States
       federal income tax;

     (b) any tax, assessment or other governmental charge which would not
  have been so imposed but for the presentation by the holder of the Notes
  for payment on a date more than 10 days after the date on which such
  payment became due and payable or the date on which payment thereof is duly
  provided for, whichever occurs later;

                                     S-10


     (c) any estate, inheritance, gift, sales, transfer, personal property or
  excise tax or any similar tax, assessment or governmental charge;

     (d) any tax, assessment or other governmental charge which is payable
  otherwise than by withholding from payments in respect of principal of,
  premium, if any, or interest, if any, on any of the Notes;

     (e) any tax, assessment or other governmental charge imposed on interest
  received by a holder or beneficial owner of the Notes who actually or
  constructively owns 10% or more of the total combined voting power of all
  classes of stock of Dow entitled to vote within the meaning of Section
  871(h)(3) of the United States Internal Revenue Code of 1986, as amended;

     (f) any tax, assessment or other governmental charge imposed as a result
  of the failure to comply with:

     . certification, information, documentation, reporting or other
       similar requirements concerning the nationality, residence, identity
       or connection with the United States of the holder or beneficial
       owner of the Notes, if such compliance is required by statute, or by
       regulation of the United States Treasury Department, as a
       precondition to relief or exemption from such tax, assessment or
       other governmental charge (including backup withholding), or

     . any other certification, information, documentation, reporting or
       other similar requirements under United States income tax laws or
       regulations that would establish entitlement to otherwise applicable
       relief or exemption from such tax, assessment or other governmental
       charge;

     (g) any tax, assessment or other governmental charge required to be
  withheld by any paying agent from any payment of the principal of, premium,
  if any, or interest, if any, on any of the Notes, if such payment can be
  made without such withholding by at least one other paying agent; or

     (h) any combination of items (a), (b), (c), (d), (e), (f) or (g);

nor will such additional amounts be paid to any holder who is a fiduciary or
partnership or other than the sole beneficial owner of the Notes to the extent
a settlor or beneficiary with respect to such fiduciary or a member of such
partnership or a beneficial owner of the Notes would not have been entitled to
payment of such additional amounts had such beneficiary, settlor, member or
beneficial owner been the holder of the Notes. The Notes are subject in all
cases to any tax, fiscal or other law or regulation or administrative or
judicial interpretation applicable thereto. Except as specifically provided
under this heading "--Payment of Additional Amounts" and under the heading "--
Redemption for Tax Reasons," Dow shall not be required to make any payment with
respect to any tax, assessment or governmental charge imposed by any government
or a political subdivision or taxing authority thereof or therein.

   As used under this heading "--Payment of Additional Amounts" and under the
headings "--Redemption for Tax Reasons" and "United States Federal Taxation--
Tax Consequences to Non-United States Persons" the term "United States" means
the United States of America (including the States and the District of
Columbia) and its territories, its possessions and other areas subject to its
jurisdiction. "United States person" has the meaning set forth under "United
States Federal Taxation--Tax Consequences to United States Persons" and "non-
United States person" has the meaning set forth under "United States Federal
Taxation--Tax Consequences to Non-United States Persons."

Redemption for Tax Reasons

   If, as a result of:

  . any change in or amendment to the laws (including any regulations or
    rulings promulgated thereunder) of the United States or any political
    subdivision thereof or therein affecting taxation, which becomes
    effective after the date of this prospectus supplement or which proposal
    is made after such date,

                                      S-11


  . any change in the official application or interpretation of such laws,
    including any official proposal for such a change, amendment or change
    in the application or interpretation of such laws, which change,
    amendment, application or interpretation is announced or becomes
    effective after the date of this prospectus supplement or which proposal
    is made after such date,

  . any action taken by any taxing authority of the United States which
    action is taken or becomes generally known after the date of this
    prospectus supplement, or any commencement of a proceeding in a court of
    competent jurisdiction in the United States after such date, whether or
    not such action was taken or such proceeding was brought with respect to
    Dow,

there is, in such case, in the written opinion of independent legal counsel of
recognized standing to Dow, a material increase in the probability that Dow has
or may become obligated to pay additional amounts (as described above under "--
Payment of Additional Amounts"), and Dow in its business judgment, determines
that such obligation cannot be avoided by the use of reasonable measures
available to it, not including assignment of the Notes, the Notes may be
redeemed, as a whole but not in part, at Dow's option at any time thereafter,
upon notice to the trustee and the holders of the Notes in accordance with the
provisions of the indenture at a redemption price equal to 100% of the
principal amount of the Notes to be redeemed together with accrued interest
thereon to the date fixed for redemption.

Notices

   Notices to holders of the Notes will be published in authorized daily
newspapers in The City of New York, in London, and, so long as the Notes are
listed on the Luxembourg Stock Exchange, in Luxembourg. It is expected that
publication will be made in The City of New York in The Wall Street Journal, in
London in the Financial Times, and in Luxembourg in the Luxemburger Wort. Any
notice given pursuant to these provisions shall be deemed to have been given on
the date of publication or, if published more than once, on the date first
published.

                         UNITED STATES FEDERAL TAXATION

   The following summary describes the material United States federal income
and certain estate tax consequences of ownership and disposition of the Notes.
This summary provides general information only and is directed solely to
original holders purchasing Notes at the "issue price", that is, the first
price to the public at which a substantial amount of the Notes in an issue is
sold (excluding sales to bond houses, brokers or similar persons or
organizations acting in the capacity of underwriters, placement agents or
wholesalers). This summary is based on the Internal Revenue Code of 1986, as
amended to the date hereof (the "Code"), existing administrative pronouncements
and judicial decisions, existing and proposed Treasury Regulations currently in
effect, and interpretations of the foregoing, changes to any of which
subsequent to the date of this prospectus supplement may affect the tax
consequences described herein, possibly with retroactive effect. This summary
discusses only Notes held as capital assets within the meaning of Section 1221
of the Code. This summary does not discuss all of the tax consequences that may
be relevant to a holder in light of the holder's particular circumstances or to
holders subject to special rules, such as certain financial institutions,
insurance companies, dealers in securities, persons holding Notes in connection
with a hedging transaction, "straddle," conversion transaction or other
integrated transaction or persons who have ceased to be United States citizens
or to be taxed as resident aliens or United States persons whose functional
currency (as defined in Section 985 of the Code) is not the U.S. dollar.
Persons considering the purchase of Notes should consult their tax advisors
with regard to the application of the United States federal income and estate
tax laws to their particular situations as well as any tax consequences arising
under the laws of any state, local or foreign taxing jurisdiction.

Tax Consequences to United States Persons

   For purposes of the following discussion, "United States person" means a
beneficial owner of a Note that is for United States federal income tax
purposes:

  . a citizen or resident of the United States,

                                      S-12


  . a corporation or other entity created or organized in or under the laws
    of the United States or of any political subdivision thereof,

  . an estate the income of which is subject to United States federal income
    taxation regardless of its source, or

  . a trust if (1) a court within the United States is able to exercise
    primary supervision over the administration of the trust and (2) one or
    more United States persons have the authority to control all substantial
    decisions of the trust.

   If a partnership holds Notes, the tax treatment of a partner will generally
depend upon the status of the partner and upon the activities of the
partnership. Partners of partnerships holding Notes should consult their tax
advisors.

Payments of Interest

   Interest on a Note will generally be taxable to a United States person as
ordinary interest income at the time it is accrued or is received in accordance
with the United States person's method of accounting for tax purposes. A United
States person that purchases a Note at issuance for an amount greater than the
Note's stated redemption price at maturity (in this case, the Note's stated
principal amount) will be considered to hold the Note with bond premium equal
to the difference. A holder of a bond premium Note may elect to reduce its
taxable interest income on the Note in each interest accrual period by the
portion of bond premium allocable to that accrual period. The portion allocable
to each interest payment or accrual is determined under Treasury regulations
and is based on the holder's yield to maturity, calculated on a constant
accrual basis from the date the holder acquires the Note, the Note's interest
accrual periods and the holder's tax basis in the Note. The election to
amortize bond premium, once made, applies to all taxable premium bonds of the
holder owned during the year of election and all subsequent years, and
generally may not be revoked without the consent of the Commissioner of
Internal Revenue. Holders of bond premium Notes should consult their tax
advisors about the advisability, time and manner of making such an election in
their own particular circumstances.

Sale, Exchange or Retirement of the Notes

   Upon the sale, exchange or retirement of a Note, a United States person will
recognize taxable gain or loss equal to the difference between the amount
realized on the sale, exchange or retirement and the United States person's
adjusted tax basis in the Note. For these purposes, the amount realized does
not include any amount attributable to interest on the Note that has not
previously been included in income, which will be includable as interest as
described under "--Payments of Interest" above. A United States person's
adjusted tax basis in a Note generally will equal the cost of the Note to the
United States person, reduced, in the case of holders of Notes who have elected
to amortize bond premium, by the amount of bond premium used as an offset to
interest accrual.

   In general, gain or loss realized on the sale, exchange or redemption of a
Note will be capital gain or loss. Prospective investors should consult their
tax advisors regarding the treatment of capital gains (which may be taxed at
lower rates than ordinary income for taxpayers who are individuals, trusts or
estates) and losses (the deductibility of which is subject to limitations).

Backup Withholding and Information Reporting

   Backup withholding and information reporting requirements may apply to
certain payments of principal, premium and interest on a Note, and to payments
of proceeds of the sale or redemption of a Note, to certain non-corporate
United States persons. Dow, its agent, a broker, or any paying agent, as the
case may be, will be required to withhold from any payment a tax equal to 31
percent of such payment if the United States person fails to furnish or certify
his correct taxpayer identification number to the payor in the manner required,
fails to certify that such United States person is not subject to backup
withholding, or otherwise fails to comply with

                                      S-13


the applicable requirements of the backup withholding rules. Any amounts
withheld under the backup withholding rules from a payment to a United States
person may be credited against that United States person's United States
federal income tax and may entitle that United States person to a refund,
provided that the required information is furnished to the United States
Internal Revenue Service.

Tax Consequences to Non-United States Persons

   As used herein, the term "non-United States person" means an owner of a Note
that is, for United States federal income tax purposes:

  . a nonresident alien individual,

  . a foreign corporation, or

  . a nonresident alien fiduciary of a foreign estate or trust.

   If a partnership holds Notes, the tax treatment of a partner will generally
depend upon the status of the partner and upon the activities of the
partnership. Partners of partnerships holding Notes should consult their tax
advisors.

Income and Withholding Tax

   Subject to the discussion of backup withholding below:

     (a) payments of principal and interest on a Note that is beneficially
  owned by a non-United States person will not be subject to United States
  federal withholding tax; provided, that in the case of interest,

     . (1) the beneficial owner does not actually or constructively own 10%
       or more of the total combined voting power of all classes of stock
       of Dow entitled to vote, (2) the beneficial owner is not a
       controlled foreign corporation that is related, directly or
       indirectly, to Dow through stock ownership, and (3) either (A) the
       beneficial owner of the Note certifies (generally on an IRS Form W-
       8BEN) to the person otherwise required to withhold United States
       federal income tax from such interest, under penalties of perjury,
       that it is not a United States person and provides its name and
       address or (B) a securities clearing organization, bank or other
       financial institution that holds customers' securities in the
       ordinary course of its trade or business (a "financial institution")
       and holds the Note certifies to the person otherwise required to
       withhold United States federal income tax from such interest, under
       penalties of perjury, that such statement has been received from the
       beneficial owner by it or by a financial institution between it and
       the beneficial owner and furnishes the payor with a copy thereof;

     . the beneficial owner is entitled to the benefits of an income tax
       treaty under which the interest is exempt from United States federal
       withholding tax and the beneficial owner of the Note or such owner's
       agent provides an IRS Form W-8BEN claiming the exemption; or

     . the beneficial owner conducts a trade or business in the United
       States to which the interest is effectively connected and the
       beneficial owner of the Note or such owner's agent provides an IRS
       Form W-8ECI;

  provided that in each such case, the relevant certification or IRS Form is
  delivered pursuant to applicable procedures and is properly transmitted to
  the person otherwise required to withhold United States federal income
  tax, and none of the persons receiving the relevant certification or IRS
  Form has actual knowledge that the certification or any statement on the
  IRS Form is false.

     (b) a non-United States person will not be subject to United States
  federal withholding tax on any gain realized on the sale, exchange or other
  disposition of a Note unless the gain is effectively connected with the
  beneficial owner's trade or business in the United States or, in the case
  of an individual, the holder is present in the United States for 183 days
  or more in the taxable year in which the sale, exchange or other
  disposition occurs and certain other conditions are met; and

                                      S-14


     (c) a Note owned by an individual who at the time of death is not, for
  United States estate tax purposes, a citizen or resident of the United
  States generally will not be subject to United States federal estate tax as
  a result of such individual's death if the individual does not actually or
  constructively own 10% or more of the total combined voting power of all
  classes of Dow's stock entitled to vote and, at the time of such
  individual's death the income on the Note would not have been effectively
  connected with a United States trade or business of the individual.

   With respect to the certification requirement referred to in subparagraph
(a), for Notes held by a foreign partnership, unless the foreign partnership
has entered into a withholding agreement with the IRS, a foreign partnership
will be required, in addition to providing a Form W-8IMY, to attach an
appropriate certification by each partner. Prospective investors, including
foreign partnerships and their partners, should consult their tax advisors
regarding possible additional reporting requirements.

   If a non-United States person holding a Note is engaged in a trade or
business in the United States, and if interest on the Note (or gain realized on
its sale, exchange or other disposition) is effectively connected with the
conduct of such trade or business, such holder, although exempt from the
withholding tax discussed in the preceding paragraphs, will generally be
subject to regular United States income tax on such effectively connected
income in the same manner as if it were a United States person. Such a holder
may also need to provide a United States taxpayer identification number on the
forms referred to in paragraph (a) above in order to meet the requirements set
forth above. In addition, if such holder is a foreign corporation, it may be
subject to a 30% branch profits tax (unless reduced or eliminated by an
applicable treaty) of its effectively connected earnings and profits for the
taxable year, subject to certain adjustments. For purposes of the branch
profits tax, interest on, and any gain recognized on the sale, exchange or
other disposition of, a Note will be included in the effectively connected
earnings and profits of such holder if such interest or gain, as the case may
be, is effectively connected with the conduct by such holder of a trade or
business in the United States.

   Each holder of a Note should be aware that if it does not properly provide
the required IRS form, or if the IRS form (or if permissible a copy of such
form) is not properly transmitted to and received by the United States person
otherwise required to withhold United States federal income tax, interest on
the Note may be subject to United States withholding tax at a 30% rate and the
holder, including the beneficial owner, will not be entitled to any additional
amounts from Dow described under the heading "Description of Notes--Payment of
Additional Amounts" with respect to such tax. Such tax, however, may in certain
circumstances be allowed as a refund or as a credit against such holder's
United States federal income tax. The foregoing does not deal with all aspects
of federal income tax withholding that may be relevant to foreign holders of
the Notes. Investors are advised to consult their own tax advisors for specific
advice concerning the ownership and disposition of Notes.

Backup Withholding and Information Reporting

   Under current Treasury Regulations, backup withholding (imposed at the rate
of 31%) will not apply to payments made by Dow or a paying agent to a non-
United States person in respect of a Note if the certifications required by
Sections 871(h) and 881(c) of the Code, which are described above, are
received, provided in each case that Dow or the paying agent, as the case may
be, does not have actual knowledge that the payee is a United States person.

   Under current Treasury Regulations, payments of the proceeds from the sale,
exchange or other disposition of a Note made to or through a foreign office of
a broker (including a custodian, nominee or other agent acting on behalf of the
beneficial owner of a Note) generally will not be subject to information
reporting or backup withholding. However, if such broker is a United States
person, a controlled foreign corporation for United States federal tax
purposes, a foreign person 50% or more of whose gross income is effectively
connected with a United States trade or business for a specified three-year
period, or a foreign partnership with certain connections with the United
States, then information reporting will be required unless the broker has in
its records documentary evidence that the beneficial owner is not a United
States person and certain other

                                      S-15


conditions are met or the beneficial owner otherwise establishes an exemption.
Backup withholding may apply to any payment that such broker is required to
report if such broker has actual knowledge that the payee is a United States
person. Payments to or through the United States office of a broker are subject
to information reporting and backup withholding unless the holder or beneficial
owner certifies, under penalties of perjury that it is a non-United States
person and that it satisfies certain other conditions or otherwise establishes
an exemption from information reporting and backup withholding.

   Non-United States persons holding Notes should consult their tax advisors
regarding the application of information reporting and backup withholding in
their particular situations, the availability of an exemption therefrom, and
the procedure for obtaining such an exemption, if available. Backup withholding
is not a separate tax, but is allowed as a refund or credit against the
holder's United States federal income tax, provided the necessary information
is furnished to the Internal Revenue Service.

   Interest on a Note that is beneficially owned by a non-United States person
will be reported annually on IRS Form 1042S, which must be filed with the
Internal Revenue Service and furnished to such beneficial owner.

   The United States federal income tax discussion set forth above is included
for general information only and may not be applicable depending upon a
holder's particular situation. Holders should consult their own tax advisors
with respect to the tax consequences to them of the ownership and disposition
of the Notes, including the tax consequences under state, local, foreign and
other tax laws and the possible effects of changes in federal or other tax
laws.

   The underwriting agreement provides that the obligations of the underwriters
to purchase the Notes included in this offering are subject to approval of
legal matters by counsel and to other conditions. The underwriters are
obligated to purchase all the Notes if they purchase any of the Notes.

   The underwriters propose to offer some of the Notes directly to the public
at the public offering price set forth on the cover page of this prospectus
supplement and some of the Notes to dealers at the public offering price less a
concession not to exceed 0.35% of the principal amount of the Notes. The
underwriters may allow, and dealers may reallow a concession not to exceed
0.25% of the principal amount of the Notes on sales to other dealers. After the
initial offering of the Notes to the public, the representative may change the
public offering price and concessions.

   The following table shows the underwriting discounts and commissions that we
are to pay to the underwriters in connection with this offering (expressed as a
percentage of the principal amount of the Notes).



                                                                     Paid by Dow
                                                                     -----------

   Although we will apply to list the Notes on the Luxembourg Stock Exchange, a
listing may not be obtained. The Notes are a new issue of securities with no
established trading market. Dow has been advised by the underwriters that the
underwriters intend to make a market in the Notes but are not obligated to do
so and may discontinue market making at any time without notice. No assurance
can be given as to the liquidity of the trading market for the Notes.

   The Notes are offered for sale in those jurisdictions in the United States,
Europe, Asia and Canada where it is legal to make such offers. Only offers and
sales of the Notes in the United States, as part of the initial distribution
thereof or in connection with resales thereof under circumstances where this
prospectus supplement and the accompanying prospectus must be delivered, are
made pursuant to the registration statement of which the accompanying
prospectus, as supplemented by this prospectus supplement, is a part.

   Each underwriter has represented and agreed that it will comply with all
applicable laws and regulations in force in any jurisdiction in which it
purchases, offers, sells or delivers the Notes or possesses or distributes this
prospectus supplement or the accompanying prospectus and will obtain any
consent, approval or permission required by it for the purchase, offer or sale
by it of the Notes under the laws and regulations in force in any jurisdiction
to which it is subject or in which it makes such purchases, offers or sales and
neither Dow nor any other underwriter shall have responsibility therefor.

   Each underwriter, severally and not jointly, represents and agrees that:

  . it has not offered or sold and will not offer or sell any Notes to
    persons in the United Kingdom prior to the expiry of the period of six
    months from the issue date of the Notes except to persons whose

                                      S-17


    ordinary activities involve them in acquiring, holding, managing or
    disposing of investments (as principal or agent) for the purposes of
    their businesses or otherwise in circumstances which have not resulted
    and will not result in an offer to the public in the United Kingdom
    within the meaning of the Public Offers of Securities Regulations 1995;

  . it has only issued or passed on and will only issue or pass on in the
    United Kingdom any document received by it in connection with the issue
    of the Notes to a person who is of a kind described in Article 11(3) of
    the Financial Services Act 1986 (Investment Advertisements) (Exemptions)
    Order 1996, as amended, or is a person to whom such document may
    otherwise lawfully be issued or passed on; and

  . it has complied and will comply with all applicable provisions of the
    Financial Services Act 1986 with respect to anything done by it in
    relation to any Notes in, from or otherwise involving the United
    Kingdom.

   In connection with the offering, Salomon Smith Barney, on behalf of the
underwriters, may purchase and sell Notes in the open market. These
transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of Notes in
excess of the principal amount of Notes to be purchased by the underwriters in
the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the Notes in the open market after the
distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of certain bids or purchases of Notes made for
the purpose of preventing or retarding a decline in the market price of the
Notes while the offering is in progress.

   The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney, in covering syndicate short positions or making
stabilizing purchases, repurchases Notes originally sold by that syndicate
member.

   Any of these activities may have the effect of preventing or retarding a
decline in the market price of the Notes. They may also cause the price of the
Notes to be higher than the price that otherwise would exist in the open market
in the absence of these transactions. The underwriters may conduct these
transactions in the over-the-counter market or otherwise. If the underwriters
commence any of these transactions, they may discontinue them at any time.

   We estimate that our total expenses for this offering will be $255,000.

   We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make because of any of those
liabilities.

                               VALIDITY OF NOTES

   The validity of the Notes will be passed upon for Dow by Charles J. Kalil,
Dow's Assistant General Counsel. As of January 29, 2001, Mr. Kalil beneficially
owned 8,347 shares, and held options to purchase 58,800 shares, of Dow common
stock, of which options to purchase 31,827 shares of Dow common stock were
exercisable. Mayer, Brown & Platt, Chicago, Illinois, will pass on certain
matters for the underwriters. Mayer, Brown & Platt from time to time represents
Dow in connection with certain matters.

                          DESCRIPTION OF CAPITAL STOCK

   The following summary of common stock and preferred stock of Dow does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the relevant provisions of Delaware law, and by Dow's certificate
of incorporation and bylaws, which are incorporated by reference as exhibits to
the registration statement of which this prospectus is a part.

   Dow is authorized to issue 1,750,000,000 shares of all classes of stock,
1,500,000,000 of which are shares of common stock, par value $2.50 per share,
and 250,000,000 of which are shares of preferred stock. As of June 30, 2000,
there were 678,216,512 shares of common stock issued and outstanding and no
shares of preferred stock issued or outstanding. All issued and outstanding
shares of common stock are fully paid and nonassessable. Any additional shares
of common stock and preferred stock that Dow issues will be fully paid and
nonassessable. Neither Dow's common stockholders nor preferred stockholders
have preemptive rights.

Common Stock

 General

   Dow's certificate of incorporation provides that, subject to all of the
rights of holders of preferred stock provided for by the board of directors or
by Delaware corporate law, the holders of common stock will have full voting
rights on all matters requiring stockholder action, with each share of common
stock being entitled to one vote and having equal rights of participation in
the dividends and assets of Dow.

                                       2


 Board of Directors

   Dow's certificate of incorporation divides Dow's board of directors into
three classes of directors that are as nearly equal in number as possible with
three-year terms. As a result, approximately one-third of Dow's board of
directors is elected each year. A quorum of directors consists of a majority of
Dow's entire board of directors then holding office.

 Number, Filling of Vacancies and Removal of Directors

   Dow's certificate of incorporation and bylaws provide that its board of
directors may not have less than six or more than twenty-one members. The
actual number of directors is determined by a vote of a majority of Dow's
entire board of directors. Currently, Dow has fifteen members on its board of
directors. Vacancies on Dow's board of directors and any newly created
directorships are filled by a vote of the majority of the other directors then
in office. Directors elected to fill a vacancy or a new position hold office
until the next annual meeting of stockholders. Directors can be removed only
for cause and only by the vote of stockholders holding 80% of the voting power
of Dow's outstanding stock entitled to vote generally in the election of
directors, voting together as a single class.

 Dividends

   Delaware corporate law generally provides that a corporation, subject to
restrictions in its certificate of incorporation, including preferred
stockholders' rights to receive dividends prior to common stockholders, may
declare and pay dividends out of:

  . surplus; or

  . net profits for the fiscal year in which the dividend is declared and/or
    the preceding fiscal year, if there is no surplus.

Dividends may not be paid out of net profits so long as the capital of the
corporation is less than the aggregate amount of capital represented by the
issued and outstanding stock of all classes having a preference on the
distribution of assets. Dividends on Dow common stock are not cumulative. Dow's
certificate of incorporation does not contain any additional restrictions on
the declaration or payment of dividends.

 Special Meetings of Stockholders

   Dow's bylaws provide that a special stockholders' meeting for any purpose
may be called only by the board of directors by a resolution adopted by a
majority of the entire board:

  . upon motion of a director; or

  . upon written request of stockholders holding at least 50% of the voting
    power of the shares of capital stock outstanding and entitled to vote
    generally in the election of directors.

   Stockholder notices requesting a special meeting must be given to Dow's
secretary. The notice must include, as to each matter the stockholder proposes
to bring before the meeting:

  . the name and address of the stockholder;

  . the class or series and number of shares of capital stock that are
    beneficially owned by the stockholder;

  . a brief description of the business to be brought before the meeting,
    including the text of any proposed amendment to the certificate of
    incorporation or bylaws;

  . a description of all arrangements or understandings between the
    stockholder and any other persons related to the business proposal;

  . any material business interests of the stockholder in the business
    proposal; and

  . a representation that the stockholder intends to appear in person or by
    proxy at the meeting to bring the business before the meeting.

                                       3


 Advance Notice Provisions for Stockholder Proposals Other than Election of
 Directors

   Dow's bylaws provide that a stockholder may bring business before an annual
stockholders' meeting if the stockholder is a stockholder on the record date of
giving notice and on the record date of the meeting and gives notice to Dow's
secretary of business that is proper to be brought at the meeting under
Delaware corporate law:

  . no earlier than 120 days or later than 60 days before the anniversary
    date of the first mailing of proxy materials for the last annual meeting;
    or

  . if the annual meeting is more than 30 days before or after the
    anniversary date of the last annual meeting, Dow must receive the
    stockholder's notice no later than the close of business on the 10th day
    after the earlier of the date on which notice of the annual meeting date
    was mailed or publicly disclosed.

   The notice must include the same information required to be included in a
stockholder's notice in connection with requesting a special meeting. See the
section of this prospectus captioned "Special Meetings of Stockholders."

 Advance Notice Provisions for Stockholder Nominations of Directors at an
 Annual Meeting

   Dow's bylaws provide that a stockholder may nominate a person for election
to the board of directors at an annual stockholders' meeting if the stockholder
gives notice to Dow's secretary:

  . no more than 120 days and no less than 60 days before the anniversary
    date of the first mailing of proxy materials for the last annual meeting;
    or

  . if the annual meeting is more than 30 days before or after the
    anniversary date of the last annual meeting, Dow must receive the
    stockholder's notice no later than the close of business on the 10th day
    after the earlier of the day on which notice of the annual meeting date
    was mailed or publicly disclosed.

   The notice must include the following:

  . a description of all arrangements or understandings between the
    stockholder and the nominee and any other person pursuant to which the
    nomination is made;

  . the information regarding the nominee that would have been required to be
    included in a proxy statement filed under the proxy rules of the
    Securities and Exchange Commission if the nominee had been nominated by
    the board of directors;

  . the consent of the nominee to serve as a director if he or she is
    elected; and

  . the information required to be included in a stockholder's notice in
    connection with requesting a special meeting. See the section of this
    prospectus captioned "Special Meetings of Stockholders."

 Advance Notice Provisions for Stockholder Nominations of Directors at a
 Special Meeting

   Dow's bylaws provide that a stockholder may nominate a person for election
to the board of directors at a special meeting of stockholders if the
stockholder gives Dow's secretary notice of the nomination no later than the
close of business on the seventh day after notice of the special meeting is
first given to stockholders.

   In addition to the information required to be included in a stockholder's
notice in connection with a special meeting, the notice must include the same
information that would be required to nominate a person for election as a
director at an annual meeting. See the section of this prospectus captioned
"Advance Notice Provisions for Stockholder Nominations of Directors at an
Annual Meeting."

 Stockholder Action by Written Consent

   Under Delaware corporate law, unless otherwise provided in a corporation's
certificate of incorporation, any action required or permitted to be taken at
an annual or special stockholders' meeting may be taken by

                                       4


written consent, without a meeting, prior notice or a vote. The written consent
must be signed by holders of outstanding stock having the minimum number of
votes necessary to authorize or take such action at a meeting at which all
shares entitled to vote on the matter were present and voted. Dow's certificate
of incorporation, however, provides that any action required or permitted to be
taken by the stockholders must be taken at a duly called annual or special
stockholders' meeting and may not be taken by written consent.

 Transactions with Interested Stockholders and a Merger or Sale of Assets

   Delaware corporate law requires the approval of the board of directors and a
majority of a corporation's outstanding stock entitled to vote to authorize a
merger or consolidation unless the company's certificate of incorporation
requires a greater percentage. Unless required by a corporation's certificate
of incorporation, stockholder approval, however, is not required in certain
cases, such as where:

  . either no shares of common stock of the surviving corporation and no
    shares, securities or obligations convertible into common stock are to be
    issued or delivered in the merger; or

  . the authorized and unissued shares or the treasury shares of common stock
    of the surviving corporation to be issued or delivered in the merger,
    plus those initially issuable upon conversion of any other shares,
    securities or obligations to be issued or delivered in the merger;

do not exceed 20% of the shares of common stock of the corporation outstanding
immediately prior to the effective date of the merger. A sale of all or
substantially all of a Delaware corporation's assets or a voluntary dissolution
of a Delaware corporation requires the vote of a majority of the board of
directors and a majority of the corporation's outstanding shares entitled to
vote on the matter unless the company's certificate of incorporation requires a
greater percentage. Dow's certificate of incorporation does not require a
greater percentage, except as described below.

   Delaware corporate law generally defines an interested stockholder as a
person, other than the corporation and any direct or indirect majority owned
subsidiary of the corporation:

  . who is the direct or indirect owner of 15% or more of the outstanding
    voting stock of the corporation; or

  . is an affiliate or associate of the corporation and was the direct or
    indirect owner of 15% or more of the outstanding voting stock of the
    corporation at any time within the three-year period immediately prior to
    the date it asked for determination of its status as an interested
    stockholder; and

  . the affiliates and associates of that person.

   Delaware corporate law prohibits an interested stockholder from engaging in
a business combination with the Delaware corporation for three years following
the time of becoming an interested stockholder. This three-year waiting period
does not apply when:

  . prior to the time of becoming an interested stockholder, the board of
    directors approves either the business combination or the transaction
    that resulted in the stockholder becoming an interested stockholder;

  . as a result of becoming an interested stockholder, the stockholder owned,
    excluding shares owned by directors who are also officers and certain
    employee stock plans, at least 85% of the outstanding voting stock of the
    corporation at the time the transaction began; or

  . at or after the time of becoming an interested stockholder, the business
    combination is approved by the board of directors and authorized at a
    meeting of stockholders by a vote of at least two-thirds of the
    outstanding voting stock that is not owned by the interested stockholder.

   These restrictions also do not apply in certain other circumstances,
including business combinations with an interested stockholder that are
proposed after a public announcement of and prior to the consummation or
abandonment of:

  . certain mergers or consolidations;

                                       5


  . sales of 50% or more of the aggregate market value of a corporation's
    assets or outstanding voting stock; or

  . tender offers or exchange offers for 50% or more of a corporation's
    voting stock.

   Delaware corporate law allows a corporation to specify in its certificate of
incorporation or bylaws that it will not be governed by the section relating to
transactions with interested stockholders. Dow has not made that election in
its certificate of incorporation or bylaws.

   Dow's certificate of incorporation provides that, in addition to the vote
required pursuant to Delaware corporate law, the vote of stockholders owning at
least 80% of the voting power of the shares of capital stock entitled to vote
generally in the election of directors, voting together as a single class, is
required to approve any of the following business combination transactions:

  . a merger or consolidation of Dow or a subsidiary of which Dow ultimately
    owns 50% or more of the capital stock with:

   -- an interested stockholder; or

   -- any other individual or entity that, after the merger or
      consolidation, would be an affiliate or associate of an interested
      stockholder;

  . a sale, lease, exchange, mortgage, pledge, transfer or other disposition,
    in one or more transactions with or on behalf of an interested
    stockholder or an affiliate or associate of an interested stockholder, of
    any assets of Dow or any subsidiary of Dow that constitutes 5% or more of
    Dow's total consolidated assets as of the end of the most recent quarter;

  . the issuance or transfer by Dow or any of its subsidiaries of any
    securities of Dow or its subsidiaries in one or more transactions to, or
    proposed by or on behalf of, an interested stockholder or an affiliate or
    associate of an interested stockholder in exchange for cash, securities
    or other property constituting not less than 5% of Dow's consolidated
    total assets as of the end of the most recent quarter;

  . the adoption of a plan or proposal for liquidation or dissolution of Dow
    or any spin-off or split-up of any kind of Dow or any subsidiary of Dow
    that is proposed by or on behalf of an interested stockholder or an
    affiliate or associate of an interested stockholder; or

  . any reclassification of securities or recapitalization of Dow, or any
    merger or consolidation of Dow with a subsidiary of Dow or other
    transaction that has the direct or indirect effect of increasing the
    percentage of the outstanding shares of:

   -- any class of equity securities of Dow or any subsidiary of Dow; or

   -- any class of securities of Dow or any subsidiary that are convertible
      into equity securities of Dow or any subsidiary that are owned
      directly or indirectly by an interested stockholder and all of its
      affiliates and associates.

   However, the vote of only a majority of the stockholders entitled to vote
generally in the election of directors, voting together as a single class, is
required to approve a business combination transaction that:

  . has been approved by a majority of continuing directors, even if they
    constitute less than a quorum; or

  . meets certain price and consideration conditions and procedures.

   A "continuing director" is:

   --  any member of the board of directors who is not an interested
      stockholder involved in a business combination described above or an
      affiliate, associate, employee, agent or nominee of an interested
      stockholder or relative of any of the foregoing persons, and was a
      member of the board before the interested stockholder became an
      interested stockholder; or

   -- a successor of a director described above who is recommended or
      elected to succeed a director described above by the vote of a
      majority of such directors then on the board.

                                       6


   Dow's certificate of incorporation defines an interested stockholder as any
person or entity other than Dow, any subsidiary of Dow or any employee benefit
plan of Dow or a subsidiary of Dow, that:

  . is, or was at any time within the two-year period prior to the date in
    question, the direct or indirect beneficial owner of 10% or more of the
    voting power of the then-outstanding voting stock of Dow;

  . is an affiliate of Dow and, at any time within the two-year period
    immediately prior to the date in question, was the direct or indirect
    beneficial owner of 10% or more of the voting power of the outstanding
    voting stock of Dow; or

  . is an assignee of, or has otherwise succeeded to, any shares of voting
    stock of Dow of which an interested stockholder was the direct or
    indirect beneficial owner, at any time within the two-year period
    immediately prior to the date in question, if such assignment or
    succession occurred in the course of a transaction or series of
    transactions not involving a public offering under the Securities Act of
    1933.

   For purposes of determining whether a person is an interested stockholder,
the outstanding voting stock of Dow includes unissued shares of voting stock of
Dow beneficially owned by the interested stockholder but not other shares of
voting stock of Dow that may be issuable pursuant to an agreement, arrangement
or understanding or upon the exercise of conversion rights, warrants or
options, or otherwise, to any person who is not an interested stockholder.

Preferred Stock

 General

   Dow's board of directors is authorized, subject to Delaware corporate law
and without a vote of its stockholders, to issue shares of preferred stock from
time to time in one or more series and to determine the voting rights,
designations, preferences and relative, participating, optional or other
special rights and qualifications, limitations and restrictions of any series
of preferred stock. The prospectus supplement relating to an offering of shares
of Dow's preferred stock will describe the terms of the series of preferred
stock Dow is offering.


                         DESCRIPTION OF DEBT SECURITIES

   The following description of the debt securities summarizes the material
terms and provisions of the debt securities to which a prospectus supplement
may relate. Each time Dow offers debt securities, the prospectus supplement
related to that offering will describe the terms of the debt securities Dow is
offering.

   The debt securities will be issued under an indenture, dated as of April 1,
1992, as supplemented by a supplemental indenture, dated as of January 1, 1994,
and a second supplemental indenture dated as of October 1, 1999, between Dow
and Bank One Trust Company, NA (successor in interest to The First National
Bank of Chicago), as trustee. The indenture as supplemented by the supplemental
indentures is referred to in this section as the "indenture." The following
summary of the debt securities and the indenture does not purport to be
complete and is subject to the provisions of the indenture, including the
defined terms. Whenever Dow refers to particular sections, articles or defined
terms of the indenture, those sections, articles or defined terms are
incorporated by reference in this prospectus and prospectus supplement. You
should review the indenture that is filed as exhibits to the registration
statement for additional information.

General

   Dow may issue debt securities from time to time in one or more series
without limitation as to aggregate principal amount. The indenture does not
limit the amount of other indebtedness or securities which Dow may issue.

                                       7


   The debt securities will be unsecured obligations and will rank equally with
all of Dow's other unsecured and unsubordinated indebtedness.

   The prospectus supplement will describe the following terms of the debt
securities Dow is offering:

  . the title of the debt securities or the series in which the debt
    securities will be included;

  . any limit on the aggregate principal amount of the debt securities of
    that series;

  . whether the debt securities may be issued as registered securities or
    bearer securities or both, whether any of the debt securities may be
    issued initially in temporary global form and whether any of the debt
    securities may be issued in permanent global form;

  . the price or prices at which the debt securities will be issued;

  . the date or dates on which the principal amount of the debt securities is
    payable;

  . the interest rate or rates, or the formula by which the interest rate or
    rates will be determined, if any, and the dates from which any interest
    will accrue;

  . the interest payment dates on which any interest will be payable, the
    regular record date for any interest payable on any debt securities that
    are registered securities on any interest payment date, and the extent to
    which, or the manner in which, any interest payable on a global security
    on an interest payment date will be paid if different from the manner
    described below under the section of this prospectus captioned "Global
    Securities";

  . any mandatory or optional sinking fund or analogous provisions;

  . each office or agency where the principal of and any premium and interest
    on the debt securities will be payable and each office or agency where
    the debt securities may be presented for registration of transfer or
    exchange;

  . the date, if any, after which and the price or prices at which the debt
    securities may, pursuant to any optional or mandatory redemption
    provisions, be redeemed, in whole or in part, and the other detailed
    terms and provisions of any optional or mandatory redemption provisions;

  . the denominations in which Dow may issue any debt securities which are
    registered securities, if other than denominations of $1,000 and any
    integral multiple thereof, and the denominations in which Dow may issue
    any debt securities which are bearer securities, if other than
    denominations of $5,000;

  . the currency or currencies of payment of principal of and any premium and
    interest on the debt securities;

  . any index used to determine the amount of payments of principal of and
    any premium and interest on the debt securities;

  . any additional covenants applicable to the debt securities; and

  . any other terms and provisions of the debt securities not inconsistent
    with the terms and provisions of the indenture.

   The prospectus supplement also will describe any special provisions for the
payment of additional amounts with respect to the debt securities.

   If the purchase price of any of the debt securities is denominated in one or
more foreign currencies or currency units or if the principal of, or any
premium and interest on, any series of debt securities is payable in one or
more foreign currencies or currency units, the restrictions, elections, general
tax considerations, specific terms and other information with respect to such
debt securities and such foreign currency or currency units will be set forth
in the related prospectus supplement.

   Some of the debt securities may be issued as original issue discount
securities (bearing no interest or bearing interest at a rate which at the time
of issuance is below market rates) to be sold at a substantial discount below
their principal amount. The prospectus supplement will describe the federal
income tax considerations and other special considerations which apply to any
original issue discount securities.

                                       8


Denominations, Registration and Transfer

   The debt securities may be issued as registered securities, bearer
securities or both. Debt securities may be issued in the form of one or more
global securities, as described below under the section of this prospectus
captioned "Global Securities." Unless otherwise provided in the prospectus
supplement, registered securities denominated in U.S. dollars will be issued
only in denominations of $1,000 or any integral multiple thereof and bearer
securities denominated in U.S. dollars will be issued only in denominations of
$5,000 with coupons attached. A global security will be issued in a
denomination equal to the aggregate principal amount of outstanding debt
securities represented by that global security. The prospectus supplement
relating to debt securities denominated in a foreign or composite currency will
specify the denominations in which the debt securities will be issued.

   During the "restricted period" as defined in Treasury Regulation Section
1.163-5(c)(2)(i)(D)(7), no bearer security will be mailed or otherwise
delivered to any location in the United States and a bearer security may be
delivered during such restricted period only if the person entitled to receive
the bearer security furnishes proper written certification that the bearer
security is owned by:

  . a person that is not a U.S. person;

  . a qualifying foreign branch of a U.S. financial institution; or

  . a U.S. person who acquired the obligation through the qualifying foreign
    branch of a U.S. financial institution and holds the obligation through
    that qualifying foreign branch of a U.S. financial institution on the
    date of certification; or

  . a financial institution for resale during the restricted period but not
    for resale directly or indirectly to a U.S. person or to a person within
    the United States or its possessions.

   Registered securities of any series may be exchanged for other registered
securities of the same series and of a like aggregate principal amount and
tenor of different authorized denominations. In addition, if debt securities of
any series may be issued as both registered securities and as bearer
securities, at the option of the holder upon written request, and subject to
the terms of the indenture, bearer securities (with all unmatured coupons,
except as provided below, and all matured coupons in default attached) of such
series may be exchanged for registered securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor.
Unless otherwise indicated in the prospectus supplement, any bearer security
surrendered in exchange for a registered security between a record date and the
relevant date for payment of interest will be surrendered without the coupon
relating to the date for payment of interest attached, and interest may be paid
only to the holder of such coupon when due in accordance with the terms of the
indenture. Except as indicated in the prospectus supplement, bearer securities
will not be issued in exchange for registered securities.

   Debt securities may be presented for exchange as described in the previous
paragraph, and registered securities, other than a global security, may be
presented for registration of transfer, with the form of transfer duly
executed, at the office of the security registrar designated by Dow or at the
office of any transfer agent designated by Dow for that purpose, without
service charge and upon payment of any taxes and other governmental charges as
described in the indenture. The transfer or exchange will be effected when the
security registrar or the transfer agent is satisfied with the documents of
title and identity of the person making the request. Dow has initially
appointed the trustee as the security registrar under the indenture. If a
prospectus supplement refers to any transfer agent initially designated by Dow
with respect to any series of debt securities, Dow may at any time cancel the
designation of the transfer agent or approve a change in the location through
which such transfer agent acts, except that:

  . if debt securities of a series may be issued only as registered
    securities, Dow will be required to maintain a transfer agent in each
    place of payment for such series; and

  . if debt securities of a series are issuable as bearer securities, Dow
    will be required to maintain (in addition to the security registrar) a
    transfer agent in a place of payment for such series located outside the
    United States.

                                       9


Dow may at any time designate additional transfer agents with respect to any
series of debt securities.

   In the event of any redemption in part, Dow will not be required to:

  . issue, register the transfer of or exchange debt securities of any series
    during a period beginning at the opening of business 15 days before the
    date of the mailing of a notice of redemption of debt securities of that
    series selected to be redeemed and ending at the close of business on:

   -- if debt securities of the series may be issued only as registered
      securities, the day of mailing of the relevant notice of redemption;
      and

   -- if debt securities of the series may be issued as bearer securities,
      the day of the first publication of the notice of redemption or, if
      debt securities of the series also may be issued as registered
      securities and there is no publication, the mailing of the relevant
      notice of redemption;

  . register the transfer of or exchange any registered security or portion
    of any registered security called for redemption, except the unredeemed
    portion of any registered security being redeemed in part; or

  . exchange any bearer security called for redemption, except to exchange
    the bearer security for a registered security of that series and like
    tenor which is immediately surrendered for redemption.

Payments and Paying Agents

   Unless otherwise indicated in the prospectus supplement, Dow will pay the
principal of and any premium and interest on registered securities other than a
global security at the office of one or more paying agents designated by Dow.
At Dow's option, however, Dow may pay any interest by check mailed to the
address of the payee entitled to the interest at the address which appears in
the security register. Unless otherwise indicated in the prospectus supplement,
payment of any installment of interest on registered securities will be made to
the person in whose name the registered security is registered at the close of
business on the record date for such interest payment.

   Unless otherwise indicated in the prospectus supplement, Dow may pay the
principal of and any premium and interest on bearer securities, subject to
applicable laws and regulations, at the offices of one or more paying agents
outside the United States designated by Dow. At Dow's option, however, Dow may
pay any interest by check or by wire transfer to an account maintained by the
payee outside the United States. Unless otherwise indicated in the prospectus
supplement, payment of interest on bearer securities on any interest payment
date will be made only upon surrender of the coupon relating to such interest
payment date. No payment with respect to any bearer security will be made at
any office or agency of Dow in the United States by check mailed to any address
in the United States or by transfer to an account maintained in the United
States. Payments will not be made in respect of bearer securities or coupons
related to such bearer securities upon presentation to or any other demand for
payment from Dow or its paying agents within the United States. Dow will pay
the principal of and any premium and interest on bearer securities denominated
and payable in U.S. dollars, however, at the office of Dow's paying agent in
the United States if, and only if:

  . payment of the full amount in U.S. dollars at all offices or agencies
    outside the United States is illegal or effectively precluded by exchange
    controls or other similar restrictions; and

  . Dow has delivered to the trustee an opinion of counsel to that effect.

   Unless otherwise indicated in the prospectus supplement, the principal
office of the trustee in New York City will be Dow's sole paying agent for
payments with respect to debt securities which may be issued only as registered
securities. Any paying agent outside the United States and any other paying
agent in the United States initially designated by Dow for the debt securities
will be named in the prospectus supplement. Dow may at any time designate
additional paying agents, or cancel the designation of any paying agent or
approve a change in the office through which any paying agent acts, except
that:

  . if debt securities of a series may be issued only as registered
    securities, Dow will be required to maintain a paying agent in each place
    of payment for such series; and

                                       10


  . if debt securities of a series may be issued as bearer securities, Dow
    will be required to maintain:

   -- a paying agent in each place of payment for such series in the United
      States for payments with respect to any registered securities of such
      series and for payments with respect to bearer securities of such
      series in the circumstances described above;

   -- a paying agent in each place of payment located outside the United
      States where debt securities of such series and any coupons related to
      the debt securities may be presented and surrendered for payment,
      provided that if the debt securities of such series are listed on The
      International Stock Exchange, London or the Luxembourg Stock Exchange
      or any other stock exchange located outside the United States and such
      stock exchange so requires, Dow will maintain a paying agent in London
      or Luxembourg City or any other required city located outside the
      United States for debt securities of such series; and

   -- a paying agent in each place of payment located outside the United
      States where, subject to applicable laws and regulations, registered
      securities of such series may be surrendered for registration of
      transfer or exchange and where notices and demands to or upon Dow may
      be served.

   All amounts paid by Dow to a paying agent for the payment of principal of
and any premium and interest on any debt security that remain unclaimed at the
end of two years after the principal, premium or interest has become due and
payable will be repaid to Dow and after such repayment the holder of the debt
security or any coupon related to the debt security may look only to Dow for
the payment of principal of and any premium and interest on any such debt
security.

Global Securities

   The debt securities of a series may be issued in whole or in part in the
form of one or more global securities that will be deposited with, or on behalf
of, a depositary identified in the prospectus supplement. Global securities may
be issued in either registered or bearer form and in either temporary or
permanent form. Unless and until it is exchanged for debt securities in
definitive form, a temporary global security in registered form may not be
transferred except as a whole by:

  . the depositary for such global security to a nominee of such depositary;

  . a nominee of the depositary for such global security to such depositary
    or another nominee of such depositary; or

  . the depository for such global security or any such nominee to a
    successor of such depositary or a nominee of such successor.

   Unless otherwise indicated in the prospectus supplement, registered debt
securities issued in global form will be represented by one or more global
securities deposited with, or on behalf of, The Depository Trust Company, New
York, New York, or other depositary Dow appoints and registered in the name of
the depository or its nominee. The debt securities will not be issued in
definitive form unless otherwise provided in the prospectus supplement.

   DTC will act as securities depository for the securities. The debt
securities will be issued as fully-registered securities registered in the name
of Cede & Co. (DTC's partnership nominee). One fully-registered global security
will be issued with respect to each $200 million of principal amount and an
additional certificate will be issued with respect to any remaining principal
amount of debt securities.

   DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants deposit with DTC. DTC
also facilitates the settlement among participants of

                                       11


securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
Direct participants include securities brokers and dealers, banks, trust
companies, clearing corporations, and certain other organizations. DTC is owned
by a number of its direct participants and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc., and the National Association of
Securities Dealers, Inc. Access to the DTC system is also available to indirect
participants such as securities brokers and dealers, banks, and trust companies
that clear through or maintain a custodial relationship with a direct
participant, either directly or indirectly. The rules applicable to DTC and its
participants are on file with the SEC.

   Purchases of debt securities under the DTC system must be made by or through
direct participants, which will receive a credit for the debt securities on
DTC's records. The ownership interest of each actual purchaser of each debt
security is in turn to be recorded on the direct and indirect participants'
records. These beneficial owners will not receive written confirmation from DTC
of their purchase, but beneficial owners are expected to receive a written
confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the direct or indirect participants through
which the beneficial owner entered into the transaction. Transfers of ownership
interests in the debt securities are to be accomplished by entries made on the
books of participants acting on behalf of beneficial owners. Beneficial owners
will not receive certificates representing their ownership interests in debt
securities, except in the event that use of the book-entry system for the debt
securities is discontinued.

   To facilitate subsequent transfers, all debt securities deposited by
participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of debt securities with DTC and their registration in
the name of Cede & Co. will effect no change in beneficial ownership. DTC has
no knowledge of the actual beneficial owners of the debt securities; DTC's
records reflect only the identity of the direct participants to whose accounts
the debt securities are credited, which may or may not be the beneficial
owners. The participants will remain responsible for keeping account of their
holdings on behalf of their customers.

   Delivery of notices and other communications by DTC to direct participants,
by direct participants to indirect participants, and by direct participants and
indirect participants to beneficial owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

   Redemption notices will be sent to DTC. If less than all of the debt
securities within an issue are being redeemed, DTC's practice is to determine
by lot the amount of the interest of each direct participant in such issue to
be redeemed.

   Neither DTC nor Cede & Co will consent or vote with respect to debt
securities. Under its usual procedures, DTC mails an omnibus proxy to Dow as
soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s
consenting or voting rights to those direct participants to whose accounts the
debt securities are credited on the record date (identified in a listing
attached to the omnibus proxy).

   Principal and interest payments, if any, on the debt securities will be made
to Cede & Co., as nominee of DTC. DTC's practice is to credit direct
participants' accounts, upon DTC's receipt of funds and corresponding detail
information from Dow or the trustee, on the applicable payable date in
accordance with their respective holdings shown on DTC's records. Payments by
participants to beneficial owners will be governed by standing instructions and
customary practices, as is the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of that participant and not of DTC, the trustee or Dow, subject
to any statutory or regulatory requirements as may be in effect from time to
time. Payment of principal and interest to Cede & Co. is Dow's responsibility
or the trustee's, disbursement of payments to direct participants shall be the
responsibility of DTC, and disbursement of payments to beneficial owners is the
responsibility of direct and indirect participants.


                                       12


   A beneficial owner must give notice to elect to have its debt securities
purchased or tendered, through its participant, to a tender agent, and shall
effect delivery of debt securities by causing the direct participants to
transfer the participant's interest in the debt securities, on DTC's records,
to a tender agent. The requirement for physical delivery of debt securities in
connection with an optional tender or a mandatory purchase will be deemed
satisfied when the ownership rights in the debt securities are transferred by
direct participants on DTC's records and followed by a book-entry credit of
tendered debt securities to the tender agent's account.

   DTC may discontinue providing its services as securities depository with
respect to the debt securities at any time by giving reasonable notice to Dow
or the trustee. Under these circumstances, in the event Dow does not appoint a
successor securities depository, debt security certificates will be printed and
delivered.

   Dow may decide to discontinue use of the system of book-entry transfers
through DTC (or a successor securities depository). In that event, debt
security certificates will be printed and delivered.

   The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that Dow believes to be reliable, but Dow takes
no responsibility for their accuracy.

Limitations on Issuance of Bearer Securities

   Bearer securities may not be offered, sold, resold or delivered during the
"restricted period" as defined in Treasury Regulation Section 1.163-
5(c)(2)(i)(D)(7) in the United States or its possessions or to U.S. persons
other than to a qualifying foreign branch of a institution, and any
underwriters, participating in the offering of debt securities must agree that
they will not:

  . offer any bearer securities for sale or resale in the United States or
    its possessions or to United States persons, other than a qualifying
    foreign branch of a U.S. financial institution); nor

  . deliver bearer securities within the United States.

   Bearer securities and any coupons related to bearer securities will bear a
legend substantially to the following effect: "Any United States person who
holds this obligation will be subject to limitations under the United States
income tax laws, including the limitations provided in Section 165(j) and
1287(a) of the Internal Revenue Code". Under Sections 165(j) and 1287(a) of the
Internal Revenue Code, holders that are U.S. persons, with certain exceptions,
will not be entitled to deduct any loss on bearer securities and must treat as
ordinary income any gain realized on the sale or other disposition (including
the receipt of principal) of bearer securities.

   The term "qualifying foreign branch of a United States financial
institution" means a branch located outside the United States of a U.S.
securities clearing organization, bank or other financial institution that
holds customers' securities in the ordinary course of its trade or business and
that provides a certificate within a reasonable time, or a blanket certificate
in the year the debt security is issued or either of the preceding two calendar

Certain Covenants of Dow

   Subject to the exceptions described below and those set forth under
"Exempted Indebtedness," Dow may not, and may not permit any restricted

additions to principal property or shares of capital stock of any restricted

    or improving property, provided that those liens are limited to the
    property acquired or constructed or the improvement and to substantially
    unimproved real property on which such construction or improvement is
    located; provided further, that Dow and restricted subsidiaries may
    further secure all or any part of such purchase price or the cost of

transaction are at least equal to the fair value of the property.

 Exempted Indebtedness

   Dow or any restricted subsidiary may create or assume liens or enter into
sale and lease-back transactions not otherwise permitted under the limitations
on liens and sale and lease-back transactions described above, so long as at
that time and after giving effect to the lien or sale and lease-back

  (1) the aggregate outstanding indebtedness of Dow and its consolidated
      subsidiaries incurred after the date of the indenture and secured by
      such liens relating to principal property; plus

  (2) the aggregate discounted value of the obligations for rental payments
      in respect to such sale and lease-back transactions relating to

    consolidated subsidiaries as shown on or reflected in its balance sheet,
    less:

      principles and current liabilities which are by their terms extendible
      or renewable at the obligor's option to a time more than 12 months
      after the time as of which the amount of current liabilities is being
      computed;

   -- advances to entities accounted for on the equity method of accounting;

   -  deferred charges, other than prepaid items such as insurance, taxes,

    reasonably determines is not material to the business conducted by Dow
    and its subsidiaries as a whole.

  .  "restricted subsidiary" means any subsidiary:

   -- of which substantially all of the property of is located, and
      substantially all of the business is carried on, within the United
      States, excluding its territories and possessions and Puerto Rico; and

     outstanding voting stock is owned, directly or indirectly, by Dow or one
     or more of its subsidiaries, or by Dow and one or more of its

Consolidation, Merger and Sale of Assets

   Dow may not merge or consolidate or sell or convey all or substantially all
of its assets unless:

  .  the successor corporation is Dow or is a domestic corporation which
     assumes Dow's obligations on the debt securities and under the
     indenture; and

  . after giving effect to such transaction, Dow or the successor corporation
    would not be in default under the indenture.

Events of Default

   With respect to any series of debt securities, any one of the following
events will constitute an event of default under the indenture:

  (1) default by Dow for 30 days in the payment of any installment of
      interest on the debt securities of such series;

                                       15


  (2) default by Dow in the payment of any principal on the debt securities
      of such series;

  (3) default by Dow in the payment of any sinking fund installment;

  (4) default by Dow in the performance of any of the covenants or warranties
      contained in the indenture for the benefit of the debt securities of
      such series which is not remedied within a period of 90 days after
      receipt of written notice by Dow from the trustee or by Dow and the
      trustee for the holders of not less than 25% in principal amount of the
      debt securities of such series then outstanding;

  (5) certain events of bankruptcy, insolvency or reorganization of Dow; or

  (6) any other event of default established in accordance with the indenture
      with respect to any series of debt securities.

   No event of default described in clauses (1), (2), (3), (4) or (6) above
with respect to a particular series of debt securities necessarily constitutes
an event of default with respect to any other series of debt securities.

   The indenture provides that if an event of default under clauses (1), (2),
(3), (4) or (6) above (but only if the event of default under clause (4) or (6)
is with respect to less than all series of debt securities then outstanding)
shall have occurred and be continuing, either the trustee or the holders of not
less than 25% in aggregate principal amount of the then outstanding debt
securities of the series affected by such event of default, each such series
treated as a separate class, may declare the principal of all the debt
securities of each such series, together with accrued interest, to be due and
payable immediately. If an Event of Default under clause (4), (5) or (6) above
(but only if the event of default under clause (4) or (6) is with respect to
all of the series of debt securities then outstanding) shall have occurred and
be continuing, either the trustee or the holders of not less than 25% in the
aggregate principal amount of all the debt securities then outstanding, treated
as one class, may declare the principal of all the debt securities, together
with accrued interest, to be due and payable immediately. Upon certain
conditions, such declaration (including a declaration caused by a default in
the payment of principal or interest, the payment for which has subsequently
been provided) may be annulled by the holders of a majority in principal amount
of the debt securities of the series then outstanding, each such series treated
as a separate class, or all debt securities treated as one class, as the case
may be, as were entitled to declare such default. In addition, past defaults
may be waived by the holders of a majority in principal amount of the debt
securities of the series then outstanding, each series treated as a separate
class, or all debt securities treated as one class, as the case may be, as were
entitled to declare such default, except a default in the payment of the
principal of or interest on the debt securities or in respect of a covenant or
provision of the indenture which cannot be modified or amended without the
approval of the holder of each debt security so affected.

   The indenture contains a provision entitling the trustee, subject to the
duty of the trustee during default to act with the required standard of care,
to be indemnified by the holders of debt securities before exercising any right
or power under the indenture at the request of the holders of the debt
securities. The indenture also provides that the holders of a majority in
principal amount of the outstanding debt securities of all series affected,
each series treated as a separate class, may direct the time, method and place
of conducting any proceeding for any remedy available to the trustee, or
exercising any trust or power conferred on the trustee, with respect to the
debt securities of such series.

   The indenture requires Dow to file annually with the trustee a certificate
as to the absence of any default or specifying any default that exists.

Satisfaction and Discharge of Indenture

   The indenture with respect to any series, except for certain specified
surviving obligations, including Dow's obligation to pay the principal of and
interest on the debt securities of such series, will be discharged and canceled
upon the satisfaction of certain conditions, including:

  . payment of all the debt securities of such series; or


                                       16


  . the deposit with the trustee of cash or U.S. government obligations or a
    combination of cash or U.S. government obligations sufficient for such
    payment or redemption in accordance with the indenture and the terms of
    the debt securities of such series.

Modification and Waiver

   Dow and the trustee may modify and amend the indenture with the consent of
the holders of more than 50% of the principal amount of the outstanding debt
securities of each series which is affected. No supplemental indenture may:

  . extend the final maturity of, reduce the rate or extend the time of
    payment of interest on, reduce the principal amount of, or reduce any
    amount payable on any redemption of, any debt securities without the
    consent of the holder of each debt security affected; or

  . reduce the percentage in principal amount of outstanding debt securities
    of any series, the consent of whose holders is required for any
    supplemental indenture, without the consent of the holders of all
    outstanding debt securities.

Governing Law

   The indenture and the debt securities are governed by and construed in
accordance with the laws of the State of New York.

warrants for the purchase of common stock or preferred stock. The stock

issue. A copy of the form of the stock warrant agreement and the stock warrant
certificate for both common stock and preferred stock is filed as an exhibit to

warrant certificate does not purport to be complete and is subject to, and

Exercise of Stock Warrants

   Stock warrants may be exercised by surrendering to the stock warrant agent
the stock warrant certificate with the form of election to purchase on the
reverse side of the certificate duly completed and signed by the warrant
holder, or its duly authorized agent, with such signature guaranteed by a bank
or trust company, by a broker or dealer which is a member of the National
Association of Securities Dealers, Inc. or by a member of a national securities

Surrendered stock warrant certificates must be accompanied by payment of the
aggregate exercise price of the stock warrants to be exercised, as set forth in
the prospectus supplement. The payment should be made in U.S. dollars, unless

request that the transfer agent issue and deliver to or upon the written order
of the exercising warrant holder, a certificate stating the number of shares of

warrants evidenced by any stock warrant certificate are exercised, the stock
warrant agent will deliver to the exercising warrant holder a new stock warrant
certificate representing the unexercised stock warrants.

entitled to vote, consent, receive dividends, receive notice as shareholder
with respect to any meeting of stockholders for election of directors of Dow or
any other matter, or exercise any rights whatsoever as stockholders of Dow.

                              PLAN OF DISTRIBUTION

   Dow may sell the securities:

  . directly to purchasers, or

  . through agents, underwriters, or dealers, or

  . through a combination of any of these methods of sale.

   Dow may distribute the securities from time to time in one or more
transactions at a fixed price or prices, which may be changed, or at market
prices prevailing at the time of sale, at prices related to the prevailing
market prices or at negotiated prices.

   Dow may determine the price or other terms of the securities offered under
this prospectus by use of an electronic auction. Dow will describe how any
auction will determine the price or any other terms, how potential investors
may participate in the auction and the nature of the underwriters' obligations
in the related supplement to this prospectus.

   Dow may designate agents to solicit offers to purchase the securities from
time to time. These agents may be deemed to be underwriters, as defined in the
Securities Act of 1933, involved in the offer or sale of the securities. The
prospectus supplement will name the agents and any commissions Dow pays them.
Agents may be entitled to indemnification by Dow against certain liabilities,
including liabilities under the Securities Act of 1933, under agreements
between Dow and the agents, and the agents or their affiliates may extend
credit to or engage in transactions with or perform services for Dow in the
ordinary course of business. Unless otherwise indicated in the prospectus
supplement, any agent will be acting on a reasonable efforts basis for the
period of its appointment.

underwriting agreement with them at the time of sale and the names of the
underwriters and the terms of the transaction will be set forth in the
prospectus supplement that the underwriters use to make resales of the
securities. The underwriters may be entitled under the relevant underwriting
agreement to indemnification by Dow against certain liabilities, including
liabilities under the Securities Act of 1933, and the underwriters or their
affiliates may extend credit to or engage in transactions with or perform
services for Dow in the ordinary course of business.

   If Dow uses dealers in the sale of the securities, Dow will sell the
securities to those dealers, as principal. The dealers may then resell the
securities to the public at varying prices to be determined by them at the time
of resale. Dealers may be entitled to indemnification by Dow against certain
liabilities, including liabilities under the Securities Act of 1933, and the
dealers or their affiliates may extend credit to or engage in transactions with

Exchange. Shares of Dow common stock also are listed on the Chicago, Pacific,
Amsterdam, Berlin, Brussels, Dusseldorf, Frankfurt, Hamburg, Hannover, London,
Paris, Switzerland and Tokyo exchanges and are traded on the Toronto, Boston,
Cincinnati and Philadelphia Exchanges. Other than the common stock, Dow does
not propose to list the offered securities on a securities exchange, and any
underwriters or dealers will not be obligated to make a market in the offered
securities. Dow may elect to list any series of offered securities on an
exchange, and in the case of the common stock, on any additional exchange, but,
unless otherwise specified in the applicable prospectus supplement, Dow will
not be obligated to do so. Dow can give no assurance as to the liquidity of the
trading market for any of the offered securities.
