                          exchange notes are identical in all material respects
                          to those of the original notes. The exchange notes,
                          however, will not contain transfer restrictions and

                         Summary of Terms of the Notes

   The form and terms of the exchange notes and the original notes are
identical in all material respects, except that transfer restrictions and
registration rights applicable to the original notes do not apply to the
exchange notes. The exchange notes will evidence the same debt as the original
notes and will be governed by the same indenture.

Exchange Notes            $1,000,000,000 principal amount of 5 1/4% Notes due
 Offered................  2004.

Maturity................  May 14, 2004.

Interest................  Interest accrues on the principal amount of the notes
                          at 5 1/4% per year. Interest is payable on the notes,
                          and distributions will be made semi-annually in
                          arrears on May 14 and November 14 of each year. The
                          first payment will be made on November 14, 2001.

Ranking.................  The notes will be our senior unsecured obligations
                          and will rank equally with all of our other senior
                          unsecured indebtedness. The notes will be effectively
                          subordinated to all liabilities of our subsidiaries,
                          including trade payables.

                          except as provided under "Description of the Notes--
                          Redemption for Tax Reasons."

                                  RISK FACTORS

   In addition to the information contained elsewhere in this prospectus, the
following risk factors should be carefully considered in evaluating the
exchange offer and an investment in the exchange notes. The following risk
factors, other than "You may have difficulty selling the original notes that
you do not exchange," generally apply to the original notes as well as the
exchange notes.

You may have difficulty selling the original notes that you do not exchange.

   If you do not exchange your original notes for exchange notes in the
exchange offer, you will continue to be subject to the restrictions on transfer
of your original notes described in the legend on your original notes. The
restrictions on transfer of your original notes arise because we issued the
original notes under exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In general, you may only offer or sell the original notes if they are
registered under the Securities Act and applicable state securities laws, or
offered and sold under an exemption from these requirements. We do not intend
to register the original notes under the Securities Act. To the extent original
notes are tendered and accepted in the exchange offer, the trading market, if
any, for the original notes would be adversely affected. See "The Exchange
Offer--Consequences of Exchanging or Failing to Exchange Original Notes."

You may find it difficult to sell your notes because there is no existing
trading market for the exchange notes.

   You may find it difficult to sell your notes because an active trading
market for the notes may not develop. The exchange notes are being offered to
the holders of the original notes. The original notes were issued on May 15,
2001 primarily to a small number of institutional investors. After the exchange
offer, the trading market for the remaining untendered original notes could be
adversely affected.

   There is no existing trading market for the exchange notes. We do not intend
to apply for listing or quotation of the exchange notes on any exchange, and so
we do not know the extent to which investor interest will lead to the
development of a trading market or how liquid that market might be. Although
Salomon Smith Barney Inc., Banc of America Securities LLC, Bear, Stearns & Co.
Inc., Banc One Capital Markets, Inc., RBC Dominion Securities Corporation and
The Williams Capital Group, L.P., the initial purchasers of the original notes,
have informed us that they intend to make a market in the exchange notes, they
are not obligated to do so, and any market-making may be discontinued at any
time without notice. As a result, the market price of the exchange notes, as
well as your ability to sell the exchange notes, could be adversely affected.

Broker-dealers or noteholders may become subject to the registration and
prospectus delivery requirements of the Securities Act.

   Any broker-dealer that:

  .  exchanges its original notes in the exchange offer for the purpose of
     participating in a distribution of the exchange notes, or

  .  resells exchange notes that were received by it for its own account in
     the exchange offer, may be deemed to have received restricted securities
     and may be required to comply with the registration and prospectus
     delivery requirements of the Securities Act in connection with any
     resale transaction by that broker-dealer. Any profit on the resale of
     the exchange notes and any commission or concessions received by a
     broker-dealer may be deemed to be underwriting compensation under the
     Securities Act.

   In addition to broker-dealers, any noteholder that exchanges its original
certificates in the exchange offer for the purpose of participating in a
distribution of the exchange notes may be deemed to have received restricted
securities and may be required to comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction by that noteholder.

                                USE OF PROCEEDS

   We will not receive any proceeds from the exchange offer. In consideration
for issuing the exchange notes, we will receive in exchange the original notes
of like principal amount, the terms of which are identical in all material
respects to the exchange notes. The original notes surrendered in exchange for
exchange notes will be retired and canceled and cannot be reissued.
Accordingly, issuance of the exchange notes will not result in any increase in
our indebtedness. We have agreed to bear the expenses of the exchange offer. No
underwriter is being used in connection with the exchange offer.

   On May 15, 2001, we issued and sold the original notes. We used the net
proceeds of that offering, which were approximately $995,500,000, for general
corporate purposes.

                       RATIO OF EARNINGS TO FIXED CHARGES

Ratio of Earnings to Fixed Charges.......     (a)      3.6x 4.3x 4.3x 6.1x 6.3x


   For the purpose of these ratios, earnings consist of income before (i)
taxes, (ii) minority interests, (iii) extraordinary items, (iv) cumulative
effect of change in accounting principle, (v) amortization of capitalized
interest and (vi) fixed charges (adjusted to exclude capitalized interest) and
after adjustment for unremitted earnings of 20%-50% owned companies. Fixed
charges consist of interest on all indebtedness, amortization of capitalized
debt costs, discount or premium and a portion of rentals deemed to represent an
interest factor. The ratios of earnings to fixed charges give retroactive
effect to our February 6, 2001 merger with Union Carbide.

(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 $697
     million.

                               THE EXCHANGE OFFER

Purpose of the Exchange Offer

   When we sold the original notes in May 2001, we entered into a registration
rights agreement with the initial purchasers of those original notes. Under the
registration rights agreement, we agreed to file a registration statement
regarding the exchange of the original notes for notes which are registered
under the Securities Act of 1933. We also agreed to use our reasonable best
efforts to cause the registration statement to become effective with the
Securities and Exchange Commission, and to conduct this exchange offer after
the registration statement is declared effective. The registration rights
agreement provides that we will be required to pay liquidated damages to the
holders of the original notes if:

  . the registration statement is not filed by August 13, 2001;

  . the registration statement is not declared effective by November 11,
    2001; or

  . the exchange offer has not been consummated by December 11, 2001.

   A copy of the registration rights agreement is filed as an exhibit to the
registration statement of which this prospectus is a part.

Terms of the Exchange Offer

   Upon the terms and conditions described in this prospectus and in the
accompanying letter of transmittal, which together constitute the exchange
offer, we will accept for exchange original notes that are properly tendered on
or before the expiration date and not withdrawn as permitted below. As used in
this prospectus, the term "expiration date" means 5:00 p.m., New York City
time, on November 27, 2001. However, if we, in our sole discretion, have
extended the period of time for which the exchange offer is open, the term
"expiration date" means the latest time and date to which we extend the
exchange offer.

   As of the date of this prospectus, $1,000,000,000 aggregate principal amount
of the original notes is outstanding. This prospectus, together with the letter
of transmittal, is first being sent on or about October 29, 2001 to all holders
of original notes known to us. Our obligation to accept original notes for
exchange in the exchange offer is subject to the conditions described below
under "--Conditions to the Exchange Offer."

   We reserve the right to extend the period of time during which the exchange
offer is open. We would then delay acceptance for exchange of any original
notes by giving oral or written notice of an extension to the holders of
original notes as described below. During any extension period, all original
notes previously tendered will remain subject to the exchange offer and may be
accepted for exchange by us. Any original notes not accepted for exchange will
be returned to the tendering holder after the expiration or termination of the
exchange offer.

   Original notes tendered in the exchange offer must be in denominations of
principal amount of $1,000 and any integral multiple of $1,000.

   We reserve the right to amend or terminate the exchange offer, and not to
accept for exchange any original notes not previously accepted for exchange,
upon the occurrence of any of the conditions of the exchange offer specified
below under "--Conditions to the Exchange Offer." We will give oral or written
notice of any extension, amendment, non-acceptance or termination to the
holders of the original notes as promptly as practicable. If we materially
change the terms of the exchange offer, we will resolicit tenders of the
original notes, file a post-effective amendment to the prospectus and provide
notice to the noteholders. If the change is made less than five business days
before the expiration of the exchange offer, we will extend the offer so that
the noteholders have at least five business days to tender or withdraw. We will
notify you of any extension by means of a press release or other public
announcement no later than 9:00 a.m., New York City time on that date.

                                       12


   Our acceptance of the tender of original notes by a tendering holder will
form a binding agreement upon the terms and subject to the conditions provided
in this prospectus and in the accompanying letter of transmittal.

Procedures for Tendering

   Except as described below, a tendering holder must, on or prior to the
expiration date:

 . transmit a properly completed and duly executed letter of transmittal,
   including all other documents required by the letter of transmittal, to
   Bank One Trust Company, N.A. at the address listed below under the heading
   "--Exchange Agent;" or

 . if original notes are tendered in accordance with the book-entry procedures
   listed below, the tendering holder must transmit an agent's message to the
   exchange agent at the address listed below under the heading "--Exchange
   Agent."

   In addition:

 . the exchange agent must receive, on or before the expiration date,
   certificates for the original notes; or

 . a timely confirmation of book-entry transfer of the original notes into the
   exchange agent's account at the Depository Trust Company, the book-entry
   transfer facility, along with the letter of transmittal or an agent's
   message; or

 . the holder must comply with the guaranteed delivery procedures described
   below.

   The Depository Trust Company will be referred to as DTC in this prospectus.

   The term "agent's message" means a message, transmitted to DTC and received
by the exchange agent and forming a part of a book-entry transfer, that states
that DTC has received an express acknowledgment that the tendering holder
agrees to be bound by the letter of transmittal and that we may enforce the
letter of transmittal against this holder.

   The method of delivery of original notes, letters of transmittal and all
other required documents is at your election and risk. If the delivery is by
mail, we recommend that you use registered mail, properly insured, with return
receipt requested. In all cases, you should allow sufficient time to assure
timely delivery. You should not send letters of transmittal or original notes
to us.

   If you are a beneficial owner whose original notes are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee, and
wish to tender, you should promptly instruct the registered holder to tender on
your behalf. Any registered holder that is a participant in DTC's book-entry
transfer facility system may make book-entry delivery of the original notes by
causing DTC to transfer the original notes into the exchange agent's account.

   Signatures on a letter of transmittal or a notice of withdrawal must be
guaranteed unless the original notes surrendered for exchange are tendered:

 . by a registered holder of the original notes who has not completed the box
   entitled "Special Issuance Instructions" or "Special Delivery Instructions"
   on the letter of transmittal, or

 . for the account of an "eligible institution."

   If signatures on a letter of transmittal or a notice of withdrawal are
required to be guaranteed, the guarantees must be by an "eligible institution."
An "eligible institution" is a financial institution, including most banks,
savings and loan associations and brokerage houses, that is a participant in
the Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Program or the Stock Exchanges Medallion Program.

                                       13


   We will determine in our sole discretion all questions as to the validity,
form and eligibility of original notes tendered for exchange. This discretion
extends to the determination of all questions concerning the timing of receipts
and acceptance of tenders. These determinations will be final and binding.

   We reserve the right to reject any particular original note not properly
tendered or any which acceptance might, in our judgment or our counsel's
judgment, be unlawful. We also reserve the right to waive any defects or
irregularities or conditions of the exchange offer as to any particular
original note either before or after the expiration date, including the right
to waive the ineligibility of any tendering holder. Our interpretation of the
terms and conditions of the exchange offer as to any particular original note
either before or after the expiration date, including the letter of transmittal
and the instructions to the letter of transmittal, shall be final and binding
on all parties. Unless waived, any defects or irregularities in connection with
tenders of original notes must be cured within a reasonable period of time.
Neither we, the exchange agent nor any other person will be under any duty to
give notification of any defect or irregularity in any tender of original
notes. Nor will we, the exchange agent or any other person incur any liability
for failing to give notification of any defect or irregularity.

   If the letter of transmittal is signed by a person other than the registered
holder of original notes, the letter of transmittal must be accompanied by a
written instrument of transfer or exchange in satisfactory form duly executed
by the registered holder with the signature guaranteed by an eligible
institution. The original notes must be endorsed or accompanied by appropriate
powers of attorney. In either case, the original notes must be signed exactly
as the name of any registered holder appears on the original notes.

   If the letter of transmittal or any original notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, these persons should so indicate when signing. Unless waived by us,
proper evidence satisfactory to us of their authority to so act must be
submitted.

   By tendering, each holder will represent to us that, among other things,

  . the exchange notes are being acquired in the ordinary course of business
    of the person receiving the exchange notes, whether or not that person is
    the holder and

  . neither the holder nor the other person has any arrangement or
    understanding with any person to participate in the distribution of the
    exchange notes.

   In the case of a holder that is not a broker-dealer, that holder, by
tendering, will also represent to us that the holder is not engaged in and does
not intend to engage in a distribution of the exchange notes.

   If any holder or other person is an "affiliate" of ours, as defined under
Rule 405 of the Securities Act, or is engaged in, or intends to engage in, or
has an arrangement or understanding with any person to participate in, a
distribution of the exchange notes, that holder or other person can not rely on
the applicable interpretations of the staff of the SEC and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction.

   Each broker-dealer that receives exchange notes for its own account in
exchange for original notes, where the original notes were acquired by it as a
result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus that meets the requirements of
the Securities Act in connection with any resale of the exchange notes. The
letter of transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. See "Plan of
Distribution."

Acceptance of Original Notes for Exchange; Delivery of Exchange Notes

   Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the expiration date, all original notes properly
tendered. We will issue the exchange notes promptly after

                                       14


acceptance of the original notes. See "--Conditions to the Exchange Offer"
below. For purposes of the exchange offer, we will be deemed to have accepted
properly tendered original notes for exchange when, as and if we have given
oral or written notice to the exchange agent, with prompt written confirmation
of any oral notice.

   For each original note accepted for exchange, the holder of the original
note will receive an exchange note having a principal amount equal to that of
the surrendered original note. The exchange notes will bear interest from the
most recent date to which interest has been paid on the original notes.
Accordingly, registered holders of exchange notes on the relevant record date
for the first interest payment date following the completion of the exchange
offer will receive interest accruing from the most recent date to which
interest has been paid. Original notes accepted for exchange will cease to
accrue interest from and after the date of completion of the exchange offer.
Holders of original notes whose original notes are accepted for exchange will
not receive any payment for accrued interest on the original notes otherwise
payable on any interest payment date the record date for which occurs on or
after completion of the exchange offer and will be deemed to have waived their
rights to receive the accrued interest on the original notes.

   In all cases, issuance of exchange notes for original notes will be made
only after timely receipt by the exchange agent of:

  . certificates for the original notes, or a timely book-entry confirmation
    of the original notes, into the exchange agent's account at the book-
    entry transfer facility;

  . a properly completed and duly executed letter of transmittal; and

  . all other required documents.

   Unaccepted or non-exchanged original notes will be returned without expense
to the tendering holder of the original notes. In the case of original notes
tendered by book-entry transfer in accordance with the book-entry procedures
described below, the non-exchanged original notes will be credited to an
account maintained with the book-entry transfer facility, as promptly as
practicable after the expiration or termination of the exchange offer.

Book-Entry Transfer

   The exchange agent will make a request to establish an account for the
original notes at DTC for purposes of the exchange offer within two business
days after the date of this prospectus. Any financial institution that is a
participant in DTC's systems must make book-entry delivery of original notes by
causing DTC to transfer those original notes into the exchange agent's account
at DTC in accordance with DTC's procedure for transfer. This participant should
transmit its acceptance to DTC on or prior to the expiration date or comply
with the guaranteed delivery procedures described below. DTC will verify this
acceptance, execute a book-entry transfer of the tendered original notes into
the exchange agent's account at DTC and then send to the exchange agent
confirmation of this book-entry transfer. The confirmation of this book-entry
transfer will include an agent's message confirming that DTC has received an
express acknowledgment from this participant that this participant has received
and agrees to be bound by the letter of transmittal and that we may enforce the
letter of transmittal against this participant. Delivery of exchange notes
issued in the exchange offer may be effected through book-entry transfer at
DTC. However, the letter of transmittal or facsimile of it or an agent's
message, with any required signature guarantees and any other required
documents, must:

  . be transmitted to and received by the exchange agent at the address
    listed below under "--Exchange Agent" on or prior to the expiration date;
    or

  . comply with the guaranteed delivery procedures described below.

Guaranteed Delivery Procedures

   If a registered holder of original notes desires to tender the original
notes, and the original notes are not immediately available, or time will not
permit the holder's original notes or other required documents to reach

                                       15


the exchange agent before the expiration date, or the procedure for book-entry
transfer described above cannot be completed on a timely basis, a tender may
nonetheless be made if:

  . the tender is made through an eligible institution;

  . prior to the expiration date, the exchange agent receives from an
    eligible institution a properly completed and duly executed letter of
    transmittal, or a facsimile of the letter of transmittal, and notice of
    guaranteed delivery, substantially in the form provided by us, by
    facsimile transmission, mail or hand delivery,

   (1) stating the name and address of the holder of original notes and the
       amount of original notes tendered,

   (2) stating that the tender is being made; and

   (3) guaranteeing that within three New York Stock Exchange trading days
       after the expiration date, the certificates for all physically
       tendered original notes, in proper form for transfer, or a book-entry
       confirmation, as the case may be, and any other documents required by
       the letter of transmittal will be deposited by the eligible
       institution with the exchange agent; and

  . the certificates for all physically tendered original notes, in proper
    form for transfer, or a book-entry confirmation, as the case may be, and
    all other documents required by the letter of transmittal, are received
    by the exchange agent within three New York Stock Exchange trading days
    after the expiration date.

Withdrawal Rights

   Tenders of original notes may be withdrawn at any time before 5:00 p.m., New
York City time, on the expiration date.

   For a withdrawal to be effective, the exchange agent must receive a written
notice of withdrawal at the address or, in the case of eligible institutions,
at the facsimile number, indicated below under "--Exchange Agent" before 5:00
p.m., New York City time, on the expiration date. Any notice of withdrawal
must:

  . specify the name of the person, referred to as the depositor, having
    tendered the original notes to be withdrawn;

  . identify the original notes to be withdrawn, including the certificate
    number or numbers and principal amount of the original notes;

  . contain a statement that the holder is withdrawing his election to have
    the original notes exchanged;

  . be signed by the holder in the same manner as the original signature on
    the letter of transmittal by which the original notes were tendered,
    including any required signature guarantees, or be accompanied by
    documents of transfer to have the trustee with respect to the original
    notes register the transfer of the original notes in the name of the
    person withdrawing the tender; and

  . specify the name in which the original notes are registered, if different
    from that of the depositor.

   If certificates for original notes have been delivered or otherwise
identified to the exchange agent, then, prior to the release of these
certificates, the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and signed notice of withdrawal with
signatures guaranteed by an eligible institution unless this holder is an
eligible institution. If original notes have been tendered in accordance with
the procedure for book-entry transfer described above, any notice of withdrawal
must specify the name and number of the account at the book-entry transfer
facility to be credited with the withdrawn original notes. We will determine
all questions as to the validity, form and eligibility, including time of
receipt, of notices of withdrawal. Any original notes so withdrawn will be
deemed not to have been validly tendered for

                                       16


exchange. No exchange notes will be issued unless the original notes so
withdrawn are validly re-tendered. Any original notes that have been tendered
for exchange, but which are not exchanged for any reason, will be returned to
the tendering holder without cost to the holder. In the case of original notes
tendered by book-entry transfer, the original notes will be credited to an
account maintained with the book-entry transfer facility for the original
notes. Properly withdrawn original notes may be re-tendered by following the
procedures described under "--Procedures for Tendering" above at any time on or
before 5:00 p.m., New York City time, on the expiration date.

Conditions to the Exchange Offer

   Notwithstanding any other provision of the exchange offer, we will not be
required to accept for exchange, or to issue exchange notes in exchange for,
any original notes, and may terminate or amend the exchange offer, if at any
time before the acceptance of the original notes for exchange or the exchange
of the exchange notes for the original notes, any of the following events
occurs:

  . there is threatened or instituted any action or proceeding in any court
    or before any governmental agency with respect to the exchange offer
    which, in our judgment, would reasonably be expected to impair our
    ability to proceed with the exchange offer;

  . any law, rule or regulation or applicable interpretation of the staff of
    the SEC is issued or promulgated which, in our good faith determination,
    does not permit us to effect the exchange offer; or

  . the exchange offer, or the making of an exchange by any holder, violates
    applicable law or any applicable interpretation of the SEC.

   These conditions to the exchange offer are for our sole benefit and we may
assert them regardless of the circumstances giving rise to any of these
conditions, or we may waive them in whole or in part in our sole discretion. If
we do so, the exchange offer will remain open for at least 5 business days
following any waiver of the preceding conditions. Our failure at any time to
exercise any of the foregoing rights will not be deemed a waiver of any right.

   In addition, we will not accept for exchange any original notes tendered,
and no exchange notes will be issued in exchange for any original notes, if at
such time any stop order is threatened or in effect relating to the
registration statement of which this prospectus constitutes a part or the
qualification of the indenture under the Trust Indenture Act of 1939.

                                       17

   If you deliver the letter of transmittal to an address other than any
address indicated above or transmit instructions via facsimile other than any
facsimile number indicated, then your delivery or transmission will not
constitute a valid delivery of the letter of transmittal.

Fees and Expenses

   We will not make any payment to brokers, dealers, or others soliciting
acceptances of the exchange offer. The cash expenses to be incurred in
connection with the exchange offer will be paid by us. We estimate these
expenses in the aggregate to be approximately $300,000.

Accounting Treatment

   We will not recognize any gain or loss for accounting purposes upon the
consummation of the exchange offer. We will amortize the expense of the
exchange offer over the term of the exchange notes under generally accepted
accounting principles.

Transfer Taxes

   Holders who tender their original notes for exchange will not be obligated
to pay any related transfer taxes, except that holders who instruct us to
register exchange notes in the name of, or request that original notes not
tendered or not accepted in the exchange offer be returned to, a person other
than the registered tendering holder will be responsible for the payment of any
applicable transfer taxes.

                                       18


Consequences of Exchanging or Failing to Exchange Original Notes

   Holders of original notes who do not exchange their original notes for
exchange notes in the exchange offer will continue to be subject to the
provisions in the indenture regarding transfer and exchange of the original
notes and the restrictions on transfer of the original notes as described in
the legend on the original notes as a consequence of the issuance of the
original notes under exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act and applicable state securities
laws. In general, the original notes may not be offered or sold, unless
registered under the Securities Act, except under an exemption from, or in a
transaction not subject to, the Securities Act and applicable state securities
laws.

   Under existing interpretations of the Securities Act by the SEC's staff
contained in several no-action letters to third parties, and subject to the
immediately following sentence, we believe that the exchange notes would
generally be freely transferable by holders after the exchange offer without
further registration under the Securities Act, subject to certain
representations required to be made by each holder of exchange notes, as set
forth below. However, any purchaser of exchange notes who is one of our
"affiliates" (as defined in Rule 405 under the Securities Act) or who intends
to participate in the exchange offer for the purpose of distributing the
exchange notes:

  .  will not be able to rely on the interpretation of the SEC's staff;

  .  will not be able to tender its original notes in the exchange offer; and

  .  must comply with the registration and prospectus delivery requirements
     of the Securities Act in connection with any sale or transfer of the
     notes unless such sale or transfer is made pursuant to an exemption from
     such requirements. See "Plan of Distribution."

   We do not intend to seek our own interpretation regarding the exchange offer
and there can be no assurance that the SEC's staff would make a similar
determination with respect to the exchange notes as it has in other
interpretations to other parties, although we have no reason to believe
otherwise.

                            DESCRIPTION OF THE NOTES

   The terms of the exchange notes to be issued in the exchange offer are
identical in all material respects to the terms of the original notes, except
for the transfer restrictions and registration rights relating to the original
notes. Any original notes that remain outstanding after the exchange offer,
together with exchange notes issued in the exchange offer, will be treated as a
single class of securities under the indenture for voting purposes.

   The notes will be issued under an indenture, dated as of April 1, 1992, as
supplemented by a first 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 (which is referred to collectively as the "indenture").

   The following discussion summarizes selected provisions of the indenture
under which the notes will be issued. Because this is only a summary, it is not
complete and does not describe every aspect of the notes and the indenture.
Whenever there is a reference to a particular defined term of the indenture,
the defined term is incorporated by reference, and the statement is qualified
in its entirety by that reference.

   A copy of the form of the indenture is available from us upon request. You
should read the indenture for provisions that may be important to you but which
are not included in this summary.

General Terms of the Notes

   The notes will be our unsecured and unsubordinated obligations and will rank
on a parity with all of our other unsecured and unsubordinated indebtedness.
The notes will be effectively subordinated to all liabilities of our
subsidiaries, including trade payables. The indenture does not limit the amount
of notes, debentures or other evidences of indebtedness that we may issue
thereunder and provides that notes, debentures or other evidences of
indebtedness may be issued from time to time in one or more series.

                                       19


   We may from time to time, without giving notice to or seeking the consent of
the holders of the notes, issue notes having the same ranking and the same
interest rate, maturity and other terms as the notes issued in this offering.
Any additional notes having such similar terms, together with the notes, will
constitute a single series of notes under the indenture.

   The notes will bear interest at 5 1/4% per annum from May 15, 2001, payable
semiannually on May 14 and November 14 of each year, commencing November 14,
2001, to the persons in whose names the notes were registered at the close of
business on the next preceding May 1 and November 1, respectively. Interest on
the notes will be computed on the basis of a 360-day year comprised of twelve
30-day months. The notes will mature on May 14, 2004 at 100% of their principal
amount. Principal and interest will be payable, and the notes will be
transferable or exchangeable, at the office or offices or agency maintained by
us for this purpose. So long as the notes are listed on the Luxembourg Stock
Exchange, principal and interest on the notes will be payable, and the notes
will be transferable or exchangeable, at the office of the Luxembourg paying
and transfer agent. Payment of interest on the notes may be made at our option
by check mailed to the registered holders.

   Any payment otherwise required to be made in respect of notes on a date that
is not a business day for the notes may be made on the next succeeding business
day with the same force and effect as if made on that date. No additional
interest shall accrue as a result of a delayed payment. A business day is
defined in the indenture as a day other than a Saturday, Sunday or other day on
which commercial banks in New York City are authorized or required by law to
close.

   The notes will be issued only in fully registered form without coupons in
denominations of $1,000 or any whole multiple of $1,000. No service charge will
be made for any transfer or exchange of the notes, but we may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
connection with a transfer or exchange. The notes will be represented by one or
more global notes registered in the name of a nominee of DTC. Except as
described under "--Book-Entry; Delivery and Form" below, the notes will not be
issuable in certificated form.

   We will initially appoint the trustee at its corporate trust office as a
paying agent, transfer agent and registrar for the notes. We have also
appointed Credit Agricole Indosuez Luxembourg, to serve as a paying agent and
transfer agent in Luxembourg. We will cause each transfer agent to act as a co-
registrar and will cause to be kept at the office of the registrar a register
in which, subject to such reasonable regulations as we may prescribe, we will
provide for the registration of the notes and registration of transfers of the
notes. We may vary or terminate the appointment of any paying agent or transfer
agent, or appoint additional or other such agents or approve any change in the
office through which any such agent acts, provided that, so long as the notes
are listed on the Luxembourg Stock Exchange, there shall at all times be a
paying agent and a transfer agent in Luxembourg. We will provide you with
notice of any resignation, termination or appointment of the trustee or any
paying agent or transfer agent, and of any change in the office through which
any such agent will act.

   The notes may not be redeemed prior to their maturity except as provided
below under "--Redemption for Tax Reasons." The notes will not be entitled to
the benefit of any mandatory redemption or sinking fund.

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. One fully-registered global security
will be issued with respect to each $400 million of principal amount and an
additional certificate will be issued with respect to any remaining principal
amount of notes. Beneficial interests in the global notes will be represented
through book-entry accounts of financial institutions acting on behalf of
beneficial owners as direct and indirect participants in DTC. Investors may
elect to hold interests in the global notes through DTC, Clearstream Banking,
societe anonyme, Luxembourg ("Clearstream"), or Euroclear Bank S.A./NV, as

                                       20


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, 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. The rules applicable to DTC and its participants are on
file with the SEC.

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

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

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

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

                                       21


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. Transfers of book-entry interests in the notes
between Euroclear and Clearstream and DTC may be effected in accordance with
procedures established for this purpose by Euroclear, Clearstream and DTC.

Global Clearance and Settlement Procedures

   Initial settlement for the notes will be made in immediately available
funds. Secondary market trading between DTC participants will occur in the
ordinary way in accordance with DTC's rules and will be settled in immediately
available funds using 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.


                                       22


   Cross-market transfers between persons holding directly or indirectly
through DTC on the one hand, and directly or indirectly through Clearstream or
Euroclear participants, on the other, will be effected by DTC in accordance
with 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 the Company as a result of such directive.

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 such notes, after deduction or withholding by us or any
paying agent for or on account of any present or future tax, assessment or
governmental charge imposed upon or as a result of such payment by the United
States or any political subdivision or taxing authority thereof or therein,
will not be less than the amount provided for in such 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

                                       23


   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 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 such notes for
payment on a date more than 10 days after the date on which such payment
became due and payable or the date on which payment thereof is duly provided
for, whichever occurs later;

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

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

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

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

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

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

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

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

   (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.

                                      24


   As used under this heading "--Payment of Additional Amounts" and under the
headings "--Redemption for Tax Reasons" and "Material Federal Tax
Considerations" 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"
and "non-United States person" have the same meanings as the terms U.S. Holder
and Non-U.S. Holder, respectively, as set forth in "Material Federal Tax
Considerations" below.

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 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 or which proposal is made
     after such date, or

  .  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 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 affected thereby in
accordance with the provisions of the indenture at a redemption price equal to
100% of the principal amount of the notes together with accrued interest
thereon to the date fixed for redemption.

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 notes. 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;

                                       25


  . 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 the
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 restricted
       subsidiaries incurred after the date of the indenture and secured by
       such liens relating to principal property, additions to principal
       property or shares of capital stock of any restricted subsidiary;
       plus

   (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.

 Certain Definitions

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

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

   .  all current liabilities, excluding current liabilities which could be
      classified as long-term debt under generally accepted accounting
      principles and current liabilities which are by their terms extendible
      or renewable at the obligor's option to a time more than 12 months
      after the time as of which the amount of current liabilities is being
      computed;

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

   .  intangible assets.

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

   .  all trade names, trademarks, licenses, patents, copyrights and
      goodwill;

   .  organizational and development costs;

   .  deferred charges, other than prepaid items such as insurance, taxes,
      interest, commissions, rents and similar items and tangible assets
      being amortized; and


                                       26


   .  amortized debt discount and expense, less unamortized premium.

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

  .  "restricted subsidiary" means any subsidiary:

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

   .  which owns or operates one or more principal properties; provided,
      however, restricted subsidiary shall not include a subsidiary which is
      primarily engaged in the business of a finance or insurance company,
      and branches of such finance or insurance company.

  .  "subsidiary" means each corporation of which more than 50% of the
     outstanding voting stock is owned, directly or indirectly, by Dow or one
     or more of its subsidiaries, or by Dow and one or more of its
     subsidiaries.

   There are no covenants or other provisions which would offer protection to
noteholders in the event of a highly leveraged transaction, rating downgrade or
similar occurrence.

Events of Default

   With respect to the notes, 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 notes;

   (2) default by Dow in the payment of any principal on the notes;

   (3) default by Dow in the performance of any of the covenants or
       warranties contained in the indenture for the benefit of the notes
       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 notes
       then outstanding; or

   (4) certain events of bankruptcy, insolvency or reorganization of Dow.

   The indenture provides that if an event of default under clauses (1), (2) or
(3) 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 notes
may declare the principal of the notes, together with accrued interest, to be
due and payable immediately. If an event of default under clauses (4) shall
have occurred and be continuing, the principal of the notes, together with
accrued interest, shall be due and payable immediately without any action on
the part of the trustee or the holders of the notes. 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 notes.
In addition, past defaults may be waived by the holders of a majority in
principal amount of the notes, except a default in the payment of the principal
of or interest on the notes 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 note 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 notes before exercising any right or power
under the indenture at the request of the holders of the notes. The indenture
also provides that the holders of a majority in principal amount of the
outstanding notes 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 notes.

                                       27


   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.

Consolidation, Merger and Sale of Assets

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

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

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

Satisfaction and Discharge of Indenture

   The indenture, except for certain specified surviving obligations, including
Dow's obligation to pay the principal of and interest on the notes, will be
discharged and canceled upon the satisfaction of certain conditions, including:

  . payment of all the notes; 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 notes.

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 notes.
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 notes without the consent of the
    holder of each note affected; or

  . reduce the percentage in principal amount of outstanding notes, the
    consent of the holders of which is required for any supplemental
    indenture, without the consent of the holders of all outstanding notes.

   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.

in accordance with, the laws of the State of New York.

                      MATERIAL FEDERAL TAX CONSIDERATIONS

   The following summary describes certain U.S. federal income and estate tax
consequences resulting from the ownership and disposition of the exchange
notes. This summary is based on the Internal Revenue Code of 1986, as amended,
administrative pronouncements, judicial decisions and existing and proposed
Treasury regulations, and interpretations of the foregoing, changes to any of
which subsequent to the date of this prospectus may affect the tax consequences
we describe below, possibly with retroactive effect. This summary discusses
only notes held as capital assets within the meaning of Section 1221 of the
Code. It does not discuss all of the tax consequences that may be relevant to a
holder in light of such holder's particular circumstances, for example,
insurance companies, tax exempt organizations, financial institutions, dealers
in securities, holders whose functional currency is not the United States
dollar and holders of the notes held as part of a "straddle," "hedge" or
"conversion transaction," and does not address U.S. state or local or foreign
tax consequences. Prospective holders should consult their tax advisors as to
the application of U.S. federal tax laws to their particular situations, as
well as any tax consequences arising under the laws of any state, local or
foreign taxing jurisdiction.

   As used herein, the term "United States Holder" means a beneficial owner of
a note that is (a) a citizen or resident of the United States for U.S. federal
income tax purposes, (b) a corporation or partnership, or any entity treated as
a corporation or partnership for U.S. federal income tax purposes, created or
organized under the laws of the United States, any state thereof or the
District of Columbia, (c) an estate the income of which is subject to U.S.
federal income tax without regard to its source or (d) a trust if (x) a court
within the United States is able to exercise primary supervision over the
administration of the trust and one or more United States persons have the
authority to control all substantial decisions of the trust or (y) the trust
has a valid election in effect under applicable U.S. Treasury regulations to be
treated as a United States Holder. If a partnership, including any entity
treated as a partnership for United States federal income tax purposes, is a
holder of the notes, the U.S. federal income tax treatment of a partner in such
a partnership will generally depend on the status of the partner and the
activities of the partnership. Partners in such a partnership should consult
their own tax advisors as to the particular federal income tax consequences
applicable to them.

   A "Non-United States Holder" is any beneficial holder of a note that is not
a United States Holder.

   For United States federal income tax purposes, a beneficial owner of an
original note will not recognize any taxable gain or loss on the exchange of
original notes for exchange notes under the exchange offer, and a beneficial
owner's tax basis and holding period in the exchange notes will be the same as
in the original notes.

United States Holders

   With the exception of a de minimis amount of original issue discount, the
exchange notes will not be issued with original issue discount. As a result,
interest on a note generally will be taxable to a United States Holder as
ordinary income as it accrues or is received in accordance with the United
States Holder's method of accounting for U.S. federal income tax purposes.

   Upon the sale, exchange, redemption, retirement, or other disposition of a
note, a United States Holder generally will recognize gain or loss equal to the
difference between the amount realized upon the sale, exchange, redemption,
retirement or other disposition, not including amounts attributable to accrued
but unpaid interest, which will be taxable as ordinary income, and such United
States Holder's adjusted tax basis in the note. A United States Holder's
adjusted tax basis in a note will, in general, be the United States Holder's
adjusted tax basis in the original note exchanged for the exchange note, less
any principal payments received by such holder. Such gain or loss will
generally be capital gain or loss. Capital gain recognized by an individual
investor upon a disposition of a note that has been held for more than 12
months will generally be subject to a maximum tax rate of 20% or, in the case
of a note that has been held for 12 months or less, will be subject to tax at
ordinary income tax rates. A United States Holder's holding period for an
exchange note will include the holding period of the original note exchanged
for the exchange note.

                                       29


Non-United States Holders

   Subject to the discussion below concerning backup withholding, payment of
interest on the notes by Dow or any paying agent to any Non-United States
Holder will not be subject to U.S. federal withholding tax, provided that (a)
such holder does not own, actually or constructively, 10% or more of the total
combined voting power of all classes of stock of Dow entitled to vote, is not a
controlled foreign corporation related, directly or indirectly, to Dow through
stock ownership and is not a bank receiving interest described in Section
881(c)(3)(A) of the Code and (b) certain certification requirements are met.
Such certification will be satisfied if the beneficial owner of the note
certifies on IRS Form W-8BEN or a substantially similar substitute form, under
penalties of perjury, that it is not a U.S. person and provides its name and
address, and (x) such beneficial owner files such form with the withholding
agent or (y) in the case of a note held through a foreign partnership or
intermediary, the beneficial owner and the foreign partnership or intermediary
satisfy the certification requirements of applicable U.S. Treasury regulations.

   Subject to the discussion below concerning backup withholding, a Non-United
States Holder of a note will not be subject to U.S. federal income tax on gain
realized on the sale, exchange or other disposition of such note, unless (a)
such holder is an individual who is present in the United States for 183 days
or more in the taxable year of disposition, and certain other conditions are
met, or (b) such gain is effectively connected with a trade or business carried
on by such holder within the United States and, if a treaty applies, and the
holder complies with applicable certification and other requirements to claim
treaty benefits, is generally attributable to a U.S. permanent establishment
maintained by the holder.

   A note held by an individual who at the time of death is not a citizen or
resident of the United States as determined for U.S. estate tax purposes will
not be subject to U.S. federal estate tax with respect to a note as a result of
such individual's death, provided that (a) the individual does not actually or
constructively own 10% or more of the total combined voting power of all
classes of our stock entitled to vote, and (b) the interest accrued on the note
was not effectively connected with the conduct of a U.S. trade or business.

Backup Withholding and Information Reporting

   Under current U.S. federal income tax law, backup withholding at a rate of
31% will not apply to payments by Dow or any paying agent thereof on a note if
(a) in the case of a United States Holder, the holder provides an accurate
taxpayer identification number, certifies that such holder is not subject to
backup withholding and does not fail to report all interest and dividends
required to be shown on its U.S. federal income tax returns, or (b) in the case
of a Non-United States Holder, the certification described above is received,
provided that Dow or the paying agent, as the case may be, does not have
knowledge that the payee is a U.S. person.

   Under current Treasury regulations, payments on the sale, exchange or other
disposition of a note made to or through a foreign office of a foreign broker
generally will not be subject to backup withholding or information reporting.
However, if such broker is, for U.S. federal income tax purposes, a U.S.
person, a controlled foreign corporation, a foreign person 50% or more of whose
gross income is effectively connected with a U.S. trade or business for a
specified three-year period or a foreign partnership with certain connections
to the United States, then information reporting will be required unless the
broker has in its records documentary evidence that the beneficial owner is not
a U.S. 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 the broker has actual knowledge that
the payee is a U.S. person. Payments to or through the U.S. office of a broker
will be subject to backup withholding and information reporting unless the
holder certifies, under penalties of perjury, that it is not a U.S. person or
otherwise establishes an exemption.

   Non-United States Holders of 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. Any amounts
withheld from a payment under the backup withholding rules will be allowed as a
credit against such holder's U.S. federal income tax liability and may entitle
such holder to a refund, provided that the required information is furnished to
the U.S. Internal Revenue Service.

                              PLAN OF DISTRIBUTION

   Each broker-dealer that receives exchange notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the exchange notes. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange notes received in exchange for original notes where
the original notes were acquired as a result of market-making activities or
other trading activities. We have agreed that, for a period of 180 days after
the expiration date of the exchange offer, we will make this prospectus
available to any broker-dealer for use in connection with any resale.

   We will not receive any proceeds from any sale of exchange notes by broker-
dealers. Exchange notes received by broker-dealers for their own account in the
exchange offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the exchange notes or a combination of these methods of resale.
These resales may be made at market prices prevailing at the time of resale, at
prices related to these prevailing market prices or negotiated prices. Any
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
broker-dealer or the purchasers of any of the exchange notes. Any broker-dealer
that resells exchange notes that were received by it for its own account in the
exchange offer and any broker or dealer that participates in a distribution of
the exchange notes may be deemed to be an underwriter within the meaning of the
Securities Act, and any profit on the resale of exchange notes and any
commission or concessions received by those persons may be deemed to be
underwriting compensation under the Securities Act. Any broker-dealer that
resells notes that were received by it for its own account in exchange offer
and any broker-dealer that participates in a distribution of those notes may be
deemed to be an underwriter within the meaning of the Securities Act and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction, including the
delivery of a prospectus that contains information with respect to any selling
holder required by the Securities Act in connection with any resale of the
exchange notes. The letter of transmittal states that, by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an underwriter within the meaning of the Securities Act.

   Furthermore, any broker-dealer that acquired any of its original notes
directly from us:

  . may not rely on the applicable interpretation of the staff of the SEC's
    position contained in Exxon Capital Holdings Corp., SEC no-action letter
    (April 13, 1988), Morgan, Stanley & Co. Inc., SEC no-action letter (June
    5, 1991) and Shearman & Sterling, SEC no-action letter (July 2, 1983);
    and

  . must also be named as a selling noteholder in connection with the
    registration and prospectus delivery requirements of the Securities Act
    relating to any resale transaction.

   For a period of 180 days after the expiration date of the exchange offer, we
will promptly send additional copies of his prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests these
documents in the letter of transmittal. We have agreed to pay all expenses
incident to the exchange offer, including the expenses of one counsel for the
holders of the notes, other than commissions or concessions of any brokers or
dealers. We will indemnify the holders of the notes, including any broker-
dealers, against various liabilities, including certain liabilities under the
Securities Act.
