                      RATIO OF EARNINGS TO FIXED CHARGES



                                         For the
                                        six months
                                          ended              For
                                        June 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 $1,408 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.

      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 six months ended June 30, 2002 and
2001 have been derived from our unaudited consolidated financial statements.
The selected consolidated financial data for the six months ended June 30, 2002
and 2001 reflect all adjustments (consisting of normal 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 reference in this
prospectus supplement and the accompanying prospectus. See "Where You Can Find
More Information."

                             DESCRIPTION OF NOTES

General

      The following description of the particular terms of the 6% Notes due
2012 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 October 1, 2012. 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 6% per annum semiannually
in arrears on April 1 and October 1 of each year, commencing April 1, 2003, to
the persons in whose names the notes are registered at the close of business on
March 15 or September 15, as the case may be (whether or not a business day),
immediately preceding the relevant interest payment date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

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

      As used in this prospectus supplement, 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

     .   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 25
         basis points, as determined by the Reference Treasury Dealer (as
         defined below),

                                      S-8



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 Merrill Lynch, Pierce, Fenner & Smith
Incorporated (or its respective affiliates which are Primary Treasury Dealers)
and its successors; provided, however, that if any of the foregoing 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.

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

                                      S-9



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
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

                                     S-10



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.

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

                                     S-11



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

      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 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

                                     S-12



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;


                                     S-13



            (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

            (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.

                                     S-14



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.

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

                                     S-15



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

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

Payments of Interest

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

Sale, Exchange or Retirement of the Notes

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

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

Backup Withholding and Information Reporting

      Backup withholding and information reporting requirements may apply to
certain payments of principal, premium and interest on a note, and to payments
of proceeds of the sale or redemption of a note, to certain non-corporate
United States persons. Dow, its agent, a broker, or any paying agent, as the
case may be, will be required to withhold from any payment a tax equal to 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.

                                     S-16



Tax Consequences to Non-United States Persons

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

             .  a nonresident alien individual,

             .  a foreign corporation, or

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

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

Income and Withholding Tax

      Subject to the discussion of backup withholding below:

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

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

             .  the beneficial owner is entitled to the benefits of an income
                tax treaty under which the interest is exempt from United
                States federal withholding tax and the beneficial owner of the
                note or such owner's agent provides an IRS Form W-8BEN claiming
                the exemption; or
             .  the beneficial owner conducts a trade or business in the United
                States to which the interest is effectively connected and the
                beneficial owner of the note or such owner's agent provides an
                IRS Form W-8ECI;

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

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

                                     S-17



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

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

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

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

Backup Withholding and Information Reporting

      Under current Treasury Regulations, backup withholding (imposed at the
rate of 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

                                     S-18



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.

      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.

to the underwriting agreement if any of these notes are purchased.

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

      The underwriters are offering the notes, subject to prior sale, when, as
and if issued to and accepted by them, subject to approval of legal matters by
their counsel, including the validity of the notes, and other conditions
contained in the underwriting agreement, such as the receipt by the
underwriters of officer's certificates and legal opinions. The underwriters
reserve the right to withdraw, cancel or modify offers to the public and to
reject orders in whole or in part.

Commissions and Discounts

      The underwriters have advised us that they propose initially to offer the
notes to the public at the public offering price on the cover page of this
prospectus, and to dealers at that price less a concession not in excess of
..30% of the principal amount of the notes. The underwriters may allow, and the
dealers may reallow, a discount not in excess of .25% of the principal amount
of the notes to other dealers. After the initial public offering, the public
offering price, concession and discount may be changed.

      The expenses of the offering, not including the underwriting discount,
are estimated to be $400,000. The underwriters have agreed to reimburse us for
such estimated expenses.

New Issue of Notes

      The notes are a new issue of securities with no established trading
market. Although we intend to apply to list the notes on the Luxembourg Stock
Exchange, a listing may not be obtained. We have been advised by the
underwriters that they presently intend to make a market in the notes after
completion of the offering. However, they are under no obligation to do so and
may discontinue any market-making activities at any time without any notice. We
cannot assure the liquidity of the trading market for the notes or that an
active public market for the notes will develop. If an active public trading
market for the notes does not develop, the market price and liquidity of the
notes may be adversely affected.

                                     S-20



Selling Restrictions

      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.

Price Stabilization and Short Positions

      In connection with the offering, the underwriters are permitted to engage
in transactions that stabilize the market price of the notes. Such transactions
consist of bids or purchases to peg, fix or maintain the price of the notes. If
the underwriters create a short position in the notes in connection with the
offering, i.e., if they sell more notes than are on the cover page of this
prospectus, the underwriters may reduce that short position by purchasing notes
in the open market. Purchases of a security to stabilize the price or to reduce
a short position could cause the price of the security to be higher than it
might be in the absence of such purchases. Neither we nor the underwriters make
any representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of the notes. In
addition, neither we nor the underwriters make any representation that the
underwriters will engage in these transactions or that these transactions, once
commenced, will not be discontinued without notice.

Other Relationships

      The underwriters and their affiliates have engaged in, and may in the
future engage in, investment banking and other commercial dealings in the
ordinary course of business with us. They have received customary fees and
commissions for these transactions.  In addition, Banc One Capital Markets,
Inc., the trustee under the indenture for the notes, is an affiliate of one of
the underwriters.

                         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 March 31, 2001,
there were 981,377,562 shares of common stock issued 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.

                                      2



  Board of Directors

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

  Number, Filling of Vacancies and Removal of Directors

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

  Dividends

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

   . surplus; or

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

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

  Special Meetings of Stockholders

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

   . upon motion of a director; or

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

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

   . the name and address of the stockholder;

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

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

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

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

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

                                      3



  Advance Notice Provisions for Stockholder Proposals Other than Election of
  Directors

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

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

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

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

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

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

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

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

   The notice must include the following:

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

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

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

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

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

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

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

  Stockholder Action by Written Consent

   Under Delaware corporate law, unless otherwise provided in a corporation's
certificate of incorporation, any action required or permitted to be taken at
an annual or special stockholders' meeting may be taken by written consent,
without a meeting, prior notice or a vote. The written consent must be signed
by holders of

                                      4



outstanding stock having the minimum number of votes necessary to authorize or
take such action at a meeting at which all shares entitled to vote on the
matter were present and voted. Dow's certificate of incorporation, however,
provides that any action required or permitted to be taken by the stockholders
must be taken at a duly called annual or special stockholders' meeting and may
not be taken by written consent.

  Transactions with Interested Stockholders and a Merger or Sale of Assets

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

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

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

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

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

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

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

   . the affiliates and associates of that person.

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

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

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

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

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

   . certain mergers or consolidations;

                                      5



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

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

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

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

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

      -- an interested stockholder; or

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

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

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

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

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

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

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

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

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

   . meets certain price and consideration conditions and procedures.

   A "continuing director" is:

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

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

                                      6



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

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

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

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

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

Preferred Stock

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

                        DESCRIPTION OF DEBT SECURITIES

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

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

General

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

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

                                      7



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

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

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

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

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

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

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

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

   . any mandatory or optional sinking fund or analogous provisions;

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

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

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

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

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

   . any additional covenants applicable to the debt securities; and

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

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

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

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

                                      8



Denominations, Registration and Transfer

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

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

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

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

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

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

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

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

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

                                      9



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

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

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

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

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

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

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

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

Payments and Paying Agents

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

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

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

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

   Unless otherwise indicated in the prospectus supplement, the principal
office of the trustee in New York City will be Dow's sole paying agent for
payments with respect to debt securities which may be issued only as registered
securities. Any paying agent outside the United States and any other paying
agent in the United States initially designated by Dow for the debt securities
will be named in the prospectus supplement. Dow may at any

                                      10



time designate additional paying agents, or cancel the designation of any
paying agent or approve a change in the office through which any paying agent
acts, except that:

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

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

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

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

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

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

Global Securities

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

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

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

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

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

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

                                      11



   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 certain other organizations. DTC is owned by a number of its
direct participants and by the New York Stock Exchange, Inc., the American
Stock Exchange, Inc., and the National Association of Securities Dealers, Inc.
Access to the DTC system is also available to indirect participants such as
securities brokers and dealers, banks, and trust companies that clear through
or maintain a custodial relationship with a direct participant, either directly
or indirectly. The rules applicable to DTC and its participants are on file
with the SEC.

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

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

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

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

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

   Principal and interest payments, if any, on the debt securities will be made
to Cede & Co., as nominee of DTC. DTC's practice is to credit direct
participants' accounts, upon DTC's receipt of funds and corresponding detail
information from Dow or the trustee, on the applicable payable date in
accordance with their respective holdings shown on DTC's records. Payments by
participants to beneficial owners will be governed by standing instructions and
customary practices, as is the case with securities held for the accounts of
customers in bearer

                                      12



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 institution, and any
underwriters, participating in the offering of debt securities must agree that
they will not:

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

   . deliver bearer securities within the United States.

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

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

                                      13



   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.

Certain Covenants of Dow

  Limitations on Liens

   Subject to the exceptions described below and those set forth under
"Exempted Indebtedness," Dow may not, and may not permit any restricted
subsidiary to create or permit to exist any lien on any principal property,
additions to principal property or shares of capital stock of any restricted
subsidiary without equally and ratably securing the debt securities. This
restriction will not apply to certain permitted liens, including:

   . liens on principal property existing at the time of its acquisition and
     certain purchase money mortgages;

   . liens existing on the date of the indenture;

   . liens on property or shares of capital stock, or arising out of any
     indebtedness of any corporation existing at the time the corporation
     becomes or is merged into Dow or a restricted subsidiary;

   . liens which secure debt owing to Dow or a subsidiary by a restricted
     subsidiary;

   . liens in connection with the issuance of tax-exempt industrial development
     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 such construction or improvement is located; provided
     further, that Dow and restricted subsidiaries may further secure all or
     any part of such purchase price or the cost of construction of such
     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, such property
     so acquired or constructed or such 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;

   . liens in favor of any customer arising in respect of certain payments made
     by or 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

   . certain statutory liens, liens for taxes and certain other liens.

  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 such 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
       such liens relating to principal property; plus


                                      14



    (2)the aggregate discounted value of the obligations for rental payments in
       respect to such 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

Events of Default

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

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

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

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

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

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

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

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

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

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

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

                                      16



Satisfaction and Discharge of Indenture

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

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

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

Modification and Waiver

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

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

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

accordance with the laws of the State of New York.

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

General

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

   . the offering price, if any;

                                      17



   . the designation and terms of the common stock or preferred stock that may
     be purchased upon exercise of the stock warrants;

     purchased upon exercise of one stock warrant and the initial price at
     which such shares may be purchased upon exercise;

   The shares of common stock or preferred stock to be issued upon exercise of
the stock warrants will, when issued in accordance with the stock warrant
agreement, be fully paid and nonassessable.

Exercise of Stock Warrants

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

     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
such exercise (except to the extent that consent of holders of debt warrants
may be required for certain modifications of the terms of the indenture 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.

supplement. Upon receipt of payment and the properly completed and duly
executed warrant certificate at the corporate trust office of the debt warrant

soon as practicable, forward the debt securities purchased upon such 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.

   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, 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.

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