                      RATIO OF EARNINGS TO FIXED CHARGES



                                       For the nine
                                       months ended            For
                                       September 30, the year ended December 31,
                                       ------------  ------------------------
                                        2002   2001  2001    2000 1999 1998 1997

    Ratio of Earnings to Fixed Charges   2.1x   (a)   (b)    3.6x 4.3x 4.3x 6.1x

--------
(a) As a result of $1,454 million in pretax costs recorded for merger-related
    expenses and restructuring, earnings for the nine months ended September
    30, 2001 were inadequate to cover fixed charges, with a deficiency of
    $626.6 million.
(b) As a result of $1,487 million in pretax costs recorded for merger-related
    expenses and restructuring, earnings for the year ended December 31, 2001
    were inadequate to cover fixed charges, with a deficiency of $582 million.

   For the purpose of these ratios, earnings consist of income before (1)
income taxes, (2) minority interests, (3) extraordinary items, (4) cumulative
effect of changes in accounting principles, (5) amortization of capitalized
interest and (6) fixed charges (adjusted to exclude capitalized interest) and
after adjustment for unremitted earnings of 20% to 50% owned companies. Fixed
charges consist of interest on all indebtedness, amortization of capitalized
debt costs, discount or premium and a portion of rentals deemed to represent an
interest factor. The ratios of earnings to fixed charges give retroactive
effect to the February 6, 2001 merger of Union Carbide Corporation with a
subsidiary of Dow, resulting in Union Carbide becoming a wholly owned
subsidiary of Dow (the "Union Carbide merger").

                     SELECTED CONSOLIDATED FINANCIAL DATA

   The selected consolidated financial data for each of the years ended
December 31, 2001, 2000, 1999 and 1998 have been derived from our audited
consolidated financial statements. The selected consolidated financial data for
the year ended December 31, 1997 and the nine months ended September 30, 2002
and 2001 have been derived from our unaudited consolidated financial
statements. The selected consolidated financial data for the nine months ended

recurring accruals) which, in the opinion of management, are considered
necessary for a fair presentation of the results for the periods covered. The
consolidated financial data have been prepared to give retroactive effect to
the Union Carbide merger and include the combined accounts of Dow and Union
Carbide for all periods presented. This data should be read in conjunction with
the consolidated financial statements and related notes incorporated by

                             DESCRIPTION OF NOTES

General

   The following description of the particular terms of the 5.75% Notes due
2009 offered by this prospectus supplement supplements the description of the
general terms and provisions of the debt securities included in the
accompanying prospectus. The notes will be issued under an indenture, dated as
of April 1, 1992, as supplemented by a supplemental indenture, dated as of
January 1, 1994, a second supplemental indenture, dated as of October 1, 1999,
and a third supplemental indenture, dated as of May 15, 2001, between us and
Bank One Trust Company, N.A. (as successor in interest to The First National
Bank of Chicago), as trustee. The following summary of the notes is qualified
in its entirety by reference to the description of the debt securities and
indenture contained in the accompanying prospectus.

   The notes will mature on November 15, 2009. The notes will be unsecured
obligations and will rank equally with all of our other unsecured and
unsubordinated indebtedness. The notes will be issued in fully registered form
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 5.75% per annum semiannually
in arrears on May 15 and November 15 of each year, commencing May 15, 2003, to
the persons in whose names the notes are registered at the close of business on
May 1 or November 1, 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, a 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.

   The notes will not have the benefit of any sinking fund.

Optional Redemption

   All or a portion of the notes may be redeemed at our option at any time or
from time to time. The redemption price for the notes to be redeemed on any
redemption date will be equal to the greater of the following amounts:

      .   100% of the principal amount of the notes being redeemed on the
          redemption date; and

                                      S-8



      .   the sum of the present values of the remaining scheduled payments of
          principal and interest on the notes being redeemed on that redemption
          date (not including any portion of any payments of interest accrued
          to the redemption date), discounted to the redemption date on a
          semiannual basis at the Treasury Rate (as defined below), plus 30
          basis points, as determined by the Reference Treasury Dealer (as
          defined below),

plus, in each case, accrued and unpaid interest on the notes to the redemption
date. Notwithstanding the foregoing, installments of interest on notes that are
due and payable on interest payment dates falling on or prior to a redemption
date will be payable on the interest payment date to the registered holders as
of the close of business on the relevant record date according to the notes and
the indenture. The redemption price will be calculated on the basis of a
360-day year consisting of twelve 30-day months.

   We will mail notice of any redemption at least 30 days but not more than 60
days before the redemption date to each registered holder of the notes to be
redeemed. Once notice of redemption is mailed, the notes called for redemption
will become due and payable on the redemption date and at the applicable
redemption price, plus accrued and unpaid interest to the redemption date.

   "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed
as a percentage of its principal amount) equal to the Comparable Treasury Price
for such redemption date.

   "Comparable Treasury Issue" means the United States Treasury security
selected by the Reference Treasury Dealer as having a maturity comparable to
the remaining term of the notes to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the notes.

   "Comparable Treasury Price" means, with respect to any redemption date, (A)
the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such Quotations, or (C) if only
one Reference Treasury Dealer Quotation is received, such Quotation.

   "Reference Treasury Dealer" means Salomon Smith Barney Inc. (or its
affiliates which are Primary Treasury Dealers) and its successors; provided,
however, that if Salomon Smith Barney shall cease to be a primary U.S.
Government securities dealer in New York City (a "Primary Treasury Dealer"), we
will substitute therefor another Primary Treasury Dealer; and (B) any other
Primary Treasury Dealer(s) selected by the trustee after consultation with us.

   "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the trustee by such Reference Treasury Dealer at 5:00 p.m. (New York
City time) on the third business day preceding such redemption date.

   On and after the redemption date, interest will cease to accrue on the notes
or any portion of the notes called for redemption (unless we default in the
payment of the redemption price and accrued interest). On or before the
redemption date, we will deposit with a paying agent (or the trustee) money
sufficient to pay the redemption price of and accrued interest on the notes to
be redeemed on that date. If less than all of the notes are to be redeemed, the
notes to be redeemed shall be selected by lot by DTC, in the case of notes
represented by a global security, or by the trustee by a method the trustee
deems to be fair and appropriate, in the case of notes that are not represented
by a global security.

                                      S-9



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.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 underwriters, 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

                                     S-10



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 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.

                                     S-11



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.

   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.

Proposed EU Directive on the Taxation of Savings Income

   The European Union is currently considering proposals for a new directive
regarding the taxation of savings income. Subject to a number of conditions
being met, it is proposed that member states of the European Union will be
required to provide to the tax authorities of another member state details of
payments of interest or other similar income paid by a paying agent resident
within its jurisdiction to an individual resident in that other member state,
subject to the right of certain member states (including possibly Luxembourg)
to opt instead for a withholding system for a transitional period in relation
to such payments. This directive, if adopted, may be conditioned on the
adoption of equivalent measures in non-European Union countries with
significant financial centers (such as the United States) and in dependent or
associated territories of certain member states. Pending agreement on the
precise text of the directive, it is difficult to say what effect, if any, the
adoption of the directive would have on the notes or payments in respect
thereof. Additional amounts, as described below, will not, in any event, be
payable by Dow as a result of such directive.

   If any such directive is implemented or any law implementing or complying
with or introduced in order to conform to such directive is introduced, Dow
will ensure that it maintains a paying agent in an EU Member State that will
not be obliged to withhold or deduct tax pursuant to any such directive or law.

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

                                     S-12



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;

      (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;

      (h) any tax, assessment or other governmental charge that is required to
   be made pursuant to any European Union directive on the taxation of savings
   income or any law implementing or complying with, or introduced to conform
   to, any such directive (see "Proposed EU Directive on the Taxation of
   Savings Income" above); or

                                     S-13



      (i) any combination of items (a) through (h), inclusive;

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,

      .   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.

                                     S-14



Concerning the Trustee

   Dow maintains banking relationships in the ordinary course of business with
the trustee's affiliate, Bank One, N.A. In addition, Banc One Capital Markets,
Inc., an affiliate of the trustee, is one of the underwriters of the notes. The
trustee's principal corporate trust office is located at 1 Bank One Plaza,
Chicago, Illinois 60670-0126. The trustee's principal office in New York City
is located at 55 Water Street, 1st Floor, Jeanette Park Entrance, New York, New
York 10041.

                        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,

      .   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.

                                     S-15



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 up to
30 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 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.

                                     S-16



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

      (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

                                     S-17



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 up to 30%) 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 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.

                                     S-18



   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

supplement and some of the notes to dealers at the public offering price less a
concession not to exceed 0.250% of the principal amount of the notes. The
underwriters may allow, and dealers may reallow a concession not to exceed
0.125% 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

   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, has represented and agreed that:

      .   it has not offered or sold and, prior to the expiry of the period of
          six months from the issue date of the notes, will not offer or sell
          any notes to persons in the United Kingdom except to persons whose
          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 communicated or caused to be communicated and will only
          communicate or cause to be communicated an invitation or inducement
          to engage investment activity (within the meaning of Section 21 of
          the Financial Services and Markets Act 2000 of the United Kingdom
          (the "FSMA")) received by it in connection with the issue of the
          notes in circumstances in which Section 21(1) of the FSMA does not
          apply to us; and

      .   it has complied and will comply with all applicable provisions of the
          FSMA 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 $350,000.

   The underwriters have performed investment banking and advisory services for
us from time to time for which they have received customary fees and expenses.
The underwriters may, from time to time, engage in transactions with us and
perform services for us in the ordinary course of their business. In addition,
Bank One Trust Company, N.A., the trustee under the indenture for the notes, is
an affiliate of one of the underwriters.

   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 November 6, 2002, Mr. Kalil beneficially
owned 1,294 shares, and held options to purchase 77,050 shares, of Dow common
stock, of which options to purchase 47,966 shares of Dow common stock were
exercisable. Mayer, Brown, Rowe & Maw, Chicago, Illinois, will pass on certain
matters for the underwriters. Mayer, Brown, Rowe & Maw from time to time
represents Dow in connection with certain matters.

                     SELECTED CONSOLIDATED FINANCIAL DATA

   The selected consolidated financial data for each of the years ended
December 31, 2001, 2000, 1999 and 1998 have been derived from our audited
consolidated financial statements. The selected consolidated financial data for
the year ended December 31, 1997 and the six months ended June 30, 2002 and

which, in the opinion of management, are considered necessary for a fair
presentation of the results for the periods covered. The consolidated financial

and include the combined accounts of Dow and Union Carbide Corporation for all

     Ratio of Earnings to Fixed Charges 2.1x  (a)  (b)   3.6x   4.3x   4.3x  6.1x


   For the purposes of these ratios, earnings consist of income before (1)
income taxes, (2) minority interests, (3) extraordinary items, (4) cumulative
effect of changes in accounting principles, (5) amortization of capitalized
interest and (6) fixed charges (adjusted to exclude capitalized interest) and
after adjustment for unremitted earnings of 20%-50% owned companies. Fixed
charges consist of interest on all indebtedness, amortization of capitalized
debt costs, discount or premium and a portion of rentals deemed to represent an
interest factor. The ratios of earnings to fixed charges give retroactive
effect to the February 6, 2001 merger of Union Carbide Corporation with a
subsidiary of Dow, resulting in Union Carbide becoming a wholly owned
subsidiary of Dow.

   (a) As a result of $1,408 million in pretax costs recorded for
merger-related expenses and restructuring, earnings for the six months ended
June 30, 2001 were inadequate to cover fixed charges, with a deficiency of $691
million.

   (b) As a result of $1,487 million in pretax costs recorded for
merger-related expenses and restructuring, earnings for the year ended December
31, 2001 were inadequate to cover fixed charges, with a deficiency of $582
million.

                                USE OF PROCEEDS

   We expect to use the net proceeds from sales of any securities described in
this prospectus for our general corporate purposes, which may include funding
capital expenditures, pursuing growth initiatives, whether through
acquisitions, joint ventures or otherwise, repaying or refinancing indebtedness
or other obligations, and financing working capital increases. Pending the
application of the net proceeds, we expect to invest the net proceeds in
marketable securities or reduce our short-term indebtedness.

                         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, 2002,
there were 910,718,107 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 non-assessable. Any additional shares
of common stock and preferred stock that Dow issues will be fully paid and
non-assessable. 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.

                                      5



  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 thirteen 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 if 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;

                                      6



  .  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.

  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."

                                      7



  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 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 employee
     stock plans in which participants do not have the right to determine
     confidentially whether shares held subject to the plan will be tendered in
     a tender or exchange offer, 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.

                                      8



   These restrictions also do not apply in other circumstances, which are set
forth in Section 203 of the Delaware General Corporation Law, 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 specified in Section 203 of the Delaware
     General Corporation Law;

  .  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 constituting 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 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 price and consideration conditions and procedures that are set forth
     in Dow's certificate of incorporation.

                                      9



   A "continuing director" is:

  --anymember 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

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

   Dow's certificate of incorporation defines an interested stockholder as any
person or entity other than Dow, any subsidiary of Dow, any employee benefit
plan of Dow or a subsidiary of Dow or any trustee or fiduciary with respect to
any employee benefit plan when acting in a fiduciary capacity, 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 the 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

   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,
a second supplemental indenture dated as of October 1, 1999, and a third
supplemental indenture dated as of May 15, 2001, between Dow and Bank One Trust
Company, N.A. (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,

                                      10



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.

   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 date 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.

                                      11



   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.

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 the 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;

  .  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 any
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 the 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.

                                      12



   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 the 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 the 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 the series located outside the United
     States.

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 the applicable 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 that 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

                                      13



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 those 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 the series; and

  .  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 the series in the United
       States for payments with respect to any registered securities of the
       series and for payments with respect to bearer securities of the series
       in the circumstances described above;

     --a paying agent in each place of payment located outside the United
       States where debt securities of the series and any coupons related to
       the debt securities may be presented and surrendered for payment,
       provided that if the debt securities of the 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 the 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 the 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 the 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 the 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 the 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 the global security to a nominee of the depositary;

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

                                      14



  .  the depository for the global security or the nominee to a successor of
     the depositary or a nominee of the 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, which we refer to as DTC, or other depositary Dow appoints and
registered in the name of the depositary 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 $400 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 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 other similar 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 the issue to be
redeemed.

                                      15



   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.

   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 U.S. financial
institution. Any underwriters participating in the offering of bearer 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
set forth in the Internal Revenue Code, 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

                                      16



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
years, stating that it agrees to comply with the requirements of Section
165(j)(3)(A), (B) or (C) of the Internal Revenue Code and its regulations.

   The term "U.S. person" means a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in or under the
laws of the United States or of any political subdivision of the United States,
and an estate or trust the income of which is subject to U.S. federal income
taxation regardless of its source.

   The term "United States" means the United States of America, including the
states and the District of Columbia.

   The term "possessions" includes Puerto Rico, the U.S. Virgin Islands, Guam,
American Samoa, Wake Island and the Northern Mariana Islands.

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

     or pollution control bonds or other similar bonds issued pursuant to
     Section 103(b) of the Internal Revenue Code to finance all or any part of
     the purchase price of or the cost of construction, equipping 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 the construction or improvement is located; provided
     further, that Dow and its restricted subsidiaries may further secure all
     or any part of such purchase price or the cost of construction of any
     improvements and personal property by an interest on additional property
     of Dow and restricted subsidiaries only to the extent necessary for the
     construction, maintenance and operation of, and access to, the property so
     acquired or constructed or the improvement;

  .  liens arising from assignments of money due under contracts with the
     United States or any State, or any department, agency or political
     subdivision of the United States or any State;

     on behalf of a customer for goods produced for or services rendered to
     customers in the ordinary course of business not exceeding the amount of
     those payments;

  .  any extension, renewal or replacement of any lien referred to in any of
     the previous clauses; and

                                      17



  Limitation on Sale and Lease-Back Transactions

   Subject to the exceptions set forth below under the section of this
prospectus captioned "Exempted Indebtedness", sale and lease-back transactions
by Dow or any restricted subsidiary of any principal property are prohibited
(except for temporary leases for a term, including any renewal thereof, of not
more than three years and except for leases between Dow and a subsidiary or
between subsidiaries) unless the net proceeds of the sale and leaseback
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
transaction, the sum of:

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

      (2) the aggregate discounted value of the obligations for rental payments
   in respect to the sale and lease-back transactions relating to principal
   property
   does not exceed 10% of consolidated net tangible assets.


   There are no covenants or provisions contained in the indenture which
protect holders of debt securities in the event of a highly leveraged
transaction.

  Certain Definitions

   The following are the meanings of terms that are important in understanding
the covenants previously described:

  .  "consolidated net tangible assets" means the total assets of Dow and its
     consolidated subsidiaries as shown on or reflected in its balance sheet,
     less:

     --all current liabilities, excluding current liabilities which could be
       classified as long-term debt under generally accepted accounting
       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;
       and

     --intangible assets.

  .  "intangible assets" means the aggregate value, net of any applicable
     reserves, as shown on or reflected in Dow's balance sheet, of:

       interest, commissions, rents and similar items and tangible assets being
       amortized; and

     --amortized debt discount and expense, less unamortized premium.

  .  "principal property" means any manufacturing facility having a gross book
     value in excess of 1% of consolidated net tangible assets that is owned by
     Dow or any restricted subsidiary and located within the United States,
     excluding its territories and possessions and Puerto Rico, other than any
     facility or portion of a facility which Dow's board of directors
     reasonably determines is not material to the business conducted by Dow and
     its subsidiaries as a whole.

                                      18



  .  "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

       however, restricted subsidiary shall not include a subsidiary which is
       primarily engaged in the business of a finance or insurance company, and
       branches of that finance or insurance company.

  .  "subsidiary" means each corporation of which more than 50% of the
     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 subsidiaries.

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 the 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 that series;

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

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

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

      (5) we commence bankruptcy or insolvency proceedings or consent to any
   bankruptcy relief sought against us;

      (6) we become involved in involuntary bankruptcy or insolvency
   proceedings and an order for relief is entered against us, if that order
   remains in effect for more than 60 consecutive days; or

      (7) any other event of default established in accordance with the
   supplemental indenture or board resolution 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 the event of default, each affected series
treated as a separate class, may declare the principal of all the debt
securities of each affected series, together

                                      19



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. If prior to any judgment or decree for the payment of
money due being entered or obtained, Dow delivers to the trustee an amount of
money sufficient to pay all interest then due and the principal of any
securities that have matured (other than through acceleration) and the
trustee's expenses and Dow has cured any defaults under the Indenture, then
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 the surviving
obligations, including Dow's obligation to compensate the trustee and to pay
the principal of and interest on the debt securities of that series, will be
discharged and canceled upon the satisfaction of specified conditions,
including:

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

  .  the deposit with the trustee of cash or U.S. government obligations or a
     combination of cash or U.S. government obligations sufficient for the
     payment or redemption in accordance with the indenture and the terms of
     the debt securities of that 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,
without the consent of the holders of all outstanding debt securities:

  .  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.

                                      20



Governing Law

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

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 the 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
exchange. The form of election should indicate the warrant holder's election to
exercise all or a portion of the stock warrants evidenced by the certificate.
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
otherwise provided in the prospectus supplement. Upon the stock warrant agent's
receipt of the surrendered stock warrant certificates and payment of the
aggregate exercise price of the stock warrants, the stock warrant agent will
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
common stock or preferred stock purchased. If less than all of the stock
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.

No Rights as Stockholders

   Holders of stock warrants, by virtue of being holders, will not be 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.

                         DESCRIPTION OF DEBT WARRANTS

   Dow may issue, alone or together with debt securities, debt warrants for the
purchase of debt securities. The debt warrants will be issued under debt
warrant agreements to be entered into between Dow and a bank or trust company,
as debt warrant agent, at the time of issue. A copy of the form of the debt
warrant agreement and debt warrant certificate is incorporated by reference as
an exhibit to the registration statement of which this prospectus forms a part.
The following summary of certain provisions of the debt warrant agreement and
the debt warrant certificates does not purport to be complete and is subject
to, and qualified in its entirety by reference to, all the provisions of the
debt warrant agreement and the debt warrant certificates, including the defined
terms.

General

   A prospectus supplement will describe the terms of the debt warrants
offered, the debt warrant agreement relating to the debt warrants and the debt
warrant certificates representing the debt warrants, including the following:

  .  the designation, aggregate principal amount and terms of the debt
     securities purchasable upon exercise of the debt warrants and the
     procedures and conditions relating to the exercise of the debt warrants;

  .  the designation and terms of any related debt securities with which the
     debt warrants are issued and the number of debt warrants issued with each
     debt security;

  .  the date, if any, on and after which the debt warrants and the related
     debt securities may be separately transferred;

  .  the principal amount of debt securities purchasable upon exercise of debt
     warrants and the price at which the principal amount of debt securities
     may be purchased upon exercise;

  .  the date on which the right to exercise the debt warrants shall commence
     and the date on which the right shall expire;

                                      22



  .  if the debt securities purchasable upon exercise of the debt warrants are
     original issue discount debt securities, a discussion of the material
     Federal income tax considerations applicable to the debt securities; and

  .  whether the debt warrants represented by the debt warrant certificates
     will be issued in registered or bearer form, and, if registered, where
     they may be transferred and registered.

   Debt warrant certificates may be exchanged for new debt warrant certificates
of different denominations and debt warrants may be exercised at the corporate
trust office of the debt warrant agent or any other office indicated in the
prospectus supplement.

No Rights as Holders of Debt Securities

   Prior to the exercise of their debt warrants, holders of debt warrants will
not have any of the rights of holders of the debt securities purchasable upon
the exercise of debt warrants (except to the extent that consent of holders of
debt warrants may be required for modifications of the terms of the indenture
pursuant to the terms of the applicable warrant agreement and a series of debt
securities issuable upon exercise of the debt warrants). In addition, holders
of debt warrants will not be entitled to payments of principal of (and premium,
if any) or interest, if any, on the debt securities purchasable upon exercise.

Exercise of Debt Warrants

   Each debt warrant will entitle the holder to purchase for cash the principal
amount of debt securities at the exercise price set forth or to be determined
as set forth in the prospectus supplement. Debt warrants may be exercised at
any time up to the close of business on the expiration date set forth in the
prospectus supplement. After the close of business on the expiration date,
unexercised debt warrants will become void.

   Debt warrants may be exercised in the manner set forth in the prospectus
supplement. Upon receipt of payment and the properly completed and duly
executed warrant certificate at the corporate trust office of the debt warrant
agent or any other office indicated in the prospectus supplement, Dow will, as
soon as practicable, forward the debt securities purchased upon any exercise.
If less than all of the debt warrants represented by the debt warrant
certificate are exercised, a new debt warrant certificate will be issued for
the remaining amount of debt warrants.

                             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.

                                      23



   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.

   If Dow uses any underwriters in the sale of any of the securities, Dow will
enter into an 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
or perform services for Dow in the ordinary course of business.

Exchange. Shares of Dow common stock also are listed on the Chicago, Pacific,
Amsterdam, Berlin, Brussels, Dusseldorf, Frankfurt, Hamburg, Hannover, London,

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.
