Summary of the Exchange Offer

On May 15, 2001, we completed the private offering of $1,000,000,000 aggregate principal amount of 5 1/4% Notes due 2004. As part of that offering, we entered into a registration rights agreement with the initial purchasers of these original notes in which we agreed, among other things, to deliver this prospectus to you and to complete an exchange offer for the original notes. Below is a summary of the exchange offer.

Securities Offered......  Up to $1,000,000,000 aggregate principal amount of
                          new 5 1/4% Notes due 2004, which have been registered
                          under the Securities Act. The form and terms of these
                          exchange notes are identical in all material respects
                          to those of the original notes. The exchange notes,
                          however, will not contain transfer restrictions and
                          registration rights applicable to the original notes.

The Exchange Offer......  We are offering to exchange new $1,000 principal
                          amount of our 5 1/4% Notes due 2004, which have been
                          registered under the Securities Act, for $1,000
                          principal amount of our outstanding 5 1/4% Notes due
                          2004.

                          In order to be exchanged, an original note must be
                          properly tendered and accepted. All original notes
                          that are validly tendered and not withdrawn will be
                          exchanged. As of the date of this prospectus, there
                          are $1,000,000,000 principal amount of original notes
                          outstanding. We will issue exchange notes promptly

Resales.................  detailed in a series of no-action letters issued to

                          issued in the exchange offer may be offered for
                          resale, resold or otherwise transferred by you

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.

Optional Redemption.....  The notes will not be redeemable prior to maturity
                          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

                                          For the six     For the year ended

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.

SELECTED CONSOLIDATED FINANCIAL DATA

The selected consolidated financial data for each of the years ended December 31, 2000, 1999 and 1998 have been derived from our audited consolidated financial statements.

The consolidated financial data have been prepared to give retroactive effect to our February 6, 2001 merger with Union Carbide 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. See "Where You Can Find More Information."

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 [ ], 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 [ ], 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.

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

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.

Governing Law

The indenture provides that it and the notes are governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

Dow maintains banking relationships in the ordinary course of business with the trustee's affiliate, Bank One, N.A. 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 14 Wall Street, Eighth Floor, New York, New York 10005.

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.

30

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.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Under Article VI of its Restated Certificate of Incorporation, as amended, Dow may indemnify its directors, officers, employees and agents to such extent as is permitted by the laws of the State of Delaware and as Dow's bylaws may from time to time provide. Section 145 of the General Corporation Law of the State of Delaware empowers Dow to indemnify, subject to the standards and limitations therein prescribed, any person in connection with any action, suit or proceeding brought or threatened by reason of the fact that such person is or was a director, officer, employee or agent of Dow or is or was serving in such capacity with respect to another corporation or other enterprise at the request of Dow. Under Section VI of Dow's bylaws, Dow is required to indemnify its directors, officers and employees to the full extent permitted by Delaware law whenever such a person is, or is threatened to be made, a defendant in any threatened, pending or completed legal proceeding. Section VI also gives Dow discretion to indemnify directors, officers, employees and agents in any threatened, pending or completed legal proceedings to which they are, or are threatened to be made, a party. Any indemnification of a director, officer, employee or agent of Dow must be approved by Dow's board of directors. Dow maintains a directors' and officers' liability insurance policy that indemnifies Dow's directors and officers against certain losses in connection with claims made against them for certain wrongful acts.

Item 22. Undertakings

The undersigned Registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement (i) to include any prospectus required by section 10(a)(3) of Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement, provided, however, that paragraphs (1) (i) and (1) (ii) do not apply if the Registration Statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement; (2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bonafied offering thereof; and (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new Registrant Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned Registrant hereby undertakes to deliver or cause to be delivered with the prospectus to each employee to whom the prospectus is sent or given a copy of the Registrant's annual report to shareholders for its last fiscal year, unless such employee otherwise has received a copy of such report, in which case the Registrant shall state in the prospectus that it will promptly furnish, without charge, a copy of such report on

II-1


written request of the employee. If the last fiscal year of the Registrant has ended within 120 days prior to the use of the prospectus, the annual report of the Registrant for the preceding fiscal year may be so delivered, but within such 120 day period the annual report for the last fiscal year will be furnished to each such employee.

The undersigned Registrant hereby undertakes to transmit or cause to be transmitted to all employees participating in the plan who do not otherwise receive such material as shareholders of the Registrant, at the time and in the manner such material is sent to its shareholders, copies all of reports, proxy statements and other communications distributed to its shareholders generally.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

144A Global Security") and the Regulation S Securities shall be issued initially in the form of one or more global Securities (collectively, the "Regulation S Global Security"), in each case without interest coupons and bearing the Global Securities Legend and Restricted Securities Legend, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Securities Custodian, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in the Indenture. One or more global securities in definitive, fully registered form without interest coupons and bearing the Global Securities Legend and the Restricted Securities Legend (collectively, the "IAI Global Security") shall also be issued on the date of this Indenture, deposited with the Securities Custodian, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in this Indenture to accommodate transfers of beneficial interests in the Securities to IAIs subsequent to the initial distribution. Beneficial ownership interests in the Regulation S Global Security shall not be exchangeable for interests in the Rule 144A Global Security, the IAI Global Security or any other Security without a Restricted Securities Legend until the expiration of the Restricted Period. The Rule 144A Global Security, the IAI Global Security and the Regulation S Global Security are each referred to herein as a "Global Security" and are collectively referred to herein as "Global Securities."

Participants shall have no rights under the Indenture with respect to any Global Security held on their behalf by the Depositary or by the Trustee as Securities Custodian or under such Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

(d) Definitive Securities. Except as provided in Section 2.5, owners of beneficial interests in Global Securities will not be entitled to receive physical delivery of certificated Securities.

SECTION 2.4 Transfer and Exchange.

6

(a) Transfer and Exchange of Definitive Securities. When Definitive Securities are presented to the Registrar with a request:

(i) to register the transfer of such Definitive Securities; or

(ii) to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange:

(A) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and

(B) are accompanied by the following additional information and documents, as applicable:

(x) if such Definitive Securities are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in the form set forth on the reverse side of the Initial Security); or

(y) if such Definitive Securities are being transferred to the Company, a certification to that effect (in the form set forth on the reverse side of the Initial Security); or

(C) if such Definitive Securities are being transferred pursuant to an exemption from registration in accordance with Rule 144 under the Securities Act or in reliance upon another exemption from the registration requirements of the Securities Act, (i) a certification to that effect (in the form set forth on the reverse side of the Initial Security) and (ii) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in
Section 2.4(e)(i).

(b) Restrictions on Transfer of a Definitive Security for a Beneficial Interest in a Global Security. A Definitive Security may not be exchanged for a beneficial interest in a Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, together with:

(i) certification (in the form set forth on the reverse side of the Initial Security) that such Definitive Security is being transferred (A) to a QIB in accordance with Rule 144A,

7

(B) to an IAI that has furnished to the Trustee a signed letter substantially in the form of Exhibit B or (C) outside the United States in an offshore transaction within the meaning of Regulation S and in compliance with Rule 904 under the Securities Act; and

(ii) written instructions directing the Trustee to make, or to direct the Securities Custodian to make, an adjustment on its books and records with respect to such Global Security to reflect an increase in the aggregate principal amount of the Securities represented by the Global Security, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Definitive Security and cause, or direct the Securities Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Securities Custodian, the aggregate principal amount of Securities represented by the Global Security to be increased by the aggregate principal amount of the Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Security equal to the principal amount of the Definitive Security so canceled. If no Global Securities are then outstanding and the Global Security has not been previously exchanged for certificated securities pursuant to Section 2.5, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers' Certificate, a new Global Security in the appropriate principal amount.

(c) Transfer and Exchange of Global Securities.

(i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depositary, in accordance with this Supplemental Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Security shall deliver a written order given in accordance with the Depositary's procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in such Global Security or another Global Security and such account shall be credited in accordance with such order with a beneficial interest in the applicable Global Security and the account of the Person making the transfer shall be debited by an amount equal to the beneficial interest in the Global Security being transferred. Transfers by an owner of a beneficial interest in a Rule 144A Global Security or an IAI Global Security to a transferee who takes delivery of such interest through a Regulation S Global Security, whether before or after the expiration of the Restricted Period, shall be made only upon receipt by the Trustee of a certification from the transferor to the effect that such transfer is being made in accordance with Regulation S or (if available) Rule 144 under the Securities Act and that, if such transfer is being made prior to the expiration of the Restricted Period, the interest transferred shall be held immediately thereafter through Euroclear or Clearstream. In the case of a transfer of a beneficial interest in either a Regulation S Global Security or a Rule 144A Global Security for an interest in an IAI Global Security, the transferee must furnish a signed letter substantially in the form of Exhibit B to the Trustee.

8

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of Global Security from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Supplemental Indenture (other than the provisions set forth in Section 2.5), a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(iv) In the event that a Global Security is exchanged for Definitive Securities pursuant to Section 2.5 prior to the consummation of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.4 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(d) Restrictions on Transfer of Regulation S Global Security.

(i) Prior to the expiration of the Restricted Period, interests in a Regulation S Global Security may only be held through Euroclear or Clearstream. During the Restricted Period, beneficial ownership interests in a Regulation S Global Security may only be sold, pledged or transferred through Euroclear or Clearstream in accordance with the Applicable Procedures and only (A) to the Company, (B) so long as such security is eligible for resale pursuant to Rule 144A, to a person whom the selling holder reasonably believes is a QIB that purchases for its own account or for the account of a QIB to whom notice is given that the resale, pledge or transfer is being made in reliance on Rule 144A, (C) in an offshore transaction in accordance with Regulation S, (D) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if applicable) under the Securities Act, (E) to an IAI purchasing for its own account, or for the account of such an IAI, in a minimum principal amount of Securities of $250,000 or (F) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any state of the United States. Prior to the expiration of the Restricted Period, transfers by an owner of a beneficial interest in a Regulation S Global Security to a transferee who takes delivery of such interest through a Rule 144A Global Security or a IAI Global Security shall be made only in accordance with the Applicable Procedures and upon receipt

9

by the Trustee of a written certification from the transferor of the beneficial interest in the form provided on the reverse of the Initial Security to the effect that such transfer is being made to (i) a person whom the transferor reasonably believes is a QIB within the meaning of Rule 144A in a transaction meeting the requirements of Rule 144A or (ii) an IAI purchasing for its own account, or for the account of such an IAI, in a minimum principal amount of the Securities of $250,000. Such written certification shall no longer be required after the expiration of the Restricted Period. In the case of a transfer of a beneficial interest in a Regulation S Global Security for an interest in a IAI Global Security, the transferee must furnish a signed letter substantially in the form of Exhibit B to the Trustee.

(ii) Upon the expiration of the Restricted Period, beneficial ownership interests in a Regulation S Global Security shall be transferable in accordance with applicable law and the other terms of the Indenture.

(e) Legends for Securities

(i) Except as permitted by the following paragraphs (ii), (iii), (iv) or (vi), each Security certificate evidencing the Global Securities and the Definitive Securities (and all Securities issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form (each defined term in the legend being defined as such for purposes of the legend only):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.

THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE "RESALE RESTRICTION TERMINATION DATE") WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH EITHER THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY), ONLY (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A UNDER THE

10

SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, (E) TO AN "ACCREDITED INVESTOR" WITHIN THE MEANING OF RULE 501(a)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT THAT IS AN INSTITUTIONAL INVESTOR ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL ACCREDITED INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF THE SECURITIES OF $250,000, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO OR FOR OFFER OR SALE IN CONNECTION WITH ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, OR (F) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHT OF THE COMPANY AND THE TRUSTEE PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D), (E) OR (F) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

Each Security evidencing a Global Security offered and sold to QIBs pursuant to Rule 144A shall bear a legend in substantially the following form:

EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF
SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

Each Definitive Security shall bear the following additional legend:

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

(ii) Upon any sale or transfer of a Transfer Restricted Security that is a Definitive Security, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a Definitive Security that does not bear the legends set forth above and rescind any restriction on the transfer of such Transfer Restricted Security if the Holder certifies in

11

writing to the Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Initial Security).

(iii) After a transfer of any Initial Securities or Private Exchange Securities during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be, all requirements pertaining to the Restricted Securities Legend on such Initial Securities or such Private Exchange Securities shall cease to apply and the requirements that any such Initial Securities or such Private Exchange Securities be issued in global form shall continue to apply.

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities pursuant to which Holders of such Initial Securities are offered Exchange Securities in exchange for their Initial Securities, all requirements pertaining to Initial Securities that Initial Securities be issued in global form shall continue to apply, and Exchange Securities in global form without the Restricted Securities Legend shall be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

(v) Upon the consummation of a Private Exchange with respect to the Initial Securities pursuant to which Holders of such Initial Securities are offered Private Exchange Securities in exchange for their Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities be issued in global form shall continue to apply, and Private Exchange Securities in global form with the Restricted Securities Legend shall be available to Holders that exchange such Initial Securities in such Private Exchange.

(vi) Upon a sale or transfer after the expiration of the Restricted Period of any Initial Security acquired pursuant to Regulation S, all requirements that such Initial Security bear the Restricted Securities Legend shall cease to apply and the requirements requiring any such Initial Security be issued in global form shall continue to apply.

(f) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, transferred, redeemed, repurchased or canceled, such Global Security shall be returned by the Depositary to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Definitive Securities, transferred in exchange for an interest in another Global Security, redeemed, repurchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(g) Obligations with Respect to Transfers and Exchanges of Securities.

12

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate, Definitive Securities and Global Securities at the Registrar's request.

(ii) No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 8.5 or 12.3 of the Indenture).

(iii) Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent or the Registrar may deem and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

(iv) The Company shall not be required to make and the Registrar need not register transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or any Securities for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed.

(v) All Securities issued upon any transfer or exchange pursuant to the terms of this Supplemental Indenture shall evidence the same debt and shall be entitled to the same benefits under the Indenture as the Securities surrendered upon such transfer or exchange.

(h) No Obligation of the Trustee.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depositary or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption or repurchase) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to the registered Holders (which shall be the Depositary or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

13

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Supplemental Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

14

SECTION 2.5 Definitive Securities.

(a) A Global Security deposited with the Depositary or with the Trustee as Securities Custodian pursuant to Section 2.3 shall be transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such transfer complies with Section 2.4 and (i) the Company notifies the Trustee that the Depositary is no longer willing or able to act as a depositary or clearing system for the Securities or the Depositary ceases to be a "clearing agency" registered under the Exchange Act, and a successor depositary or clearing system is not appointed by the Company within 90 days of such notice or cessation, (ii) the Company, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under the Indenture, or (iii) upon the occurrence and continuation of an Event of Default.

(b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.5 shall be surrendered by the Depositary to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section 2.5 shall be executed, authenticated and delivered only in denominations of $1,000 of principal amount and any integral multiple thereof and registered in such names as the Depositary shall direct. Any certificated Initial Security in the form of a Definitive Security delivered in exchange for an interest in the Global Security shall, except as otherwise provided by Section 2.4, bear the Restricted Securities Legend.

(c) The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under the Indenture or the Securities.

THE DOW CHEMICAL COMPANY, a Delaware corporation (herein called the "Company," which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum set forth above or such other principal sum set forth on the Schedule attached hereto (which shall not exceed US$400,000,000) on May 14, 2004, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, and to pay interest (which term shall include any additional interest required to be paid upon the occurrence of a Registration Default (as defined below)), together with such additional amounts (if any) as are described in Section 2 on the reverse of this Note ("Additional Amounts"), thereon semi-annually on each May 14 and November 14, commencing November 14, 2001 and at maturity on said principal sum, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, from May 14 and November 14, as the case may be, next preceding the date of this Security to which interest has been paid, unless the date hereof is a date to which interest has been paid, in which case from the date of this Security, or unless no interest has been paid on this Security, in which case from May 15, 2001, until payment

A-1

of said principal sum has been made or duly provided for, at the rate per annum specified in the title of this Security; provided, that in the event (each such event in clauses (i) through (v) below being referred to as a "Registration Default") that: (i) the Exchange Offer Registration Statement is not filed with the Commission on or prior to the 90th calendar day after the Closing Date, (ii) the Exchange Offer Registration Statement is not declared effective on or prior to the 180th calendar day after the Closing Date, (iii) the Exchange Offer is not consummated on or prior to the 210th calendar day following the Closing Date, or (iv) if required, a Shelf Registration Statement with respect to the Registrable Securities is not filed with the Commission on or prior to the 30th calendar day after such filing obligation arises or is not declared effective on or prior to the 45th calendar day after the filing thereof, or (v) the Election Periods exceed, in the aggregate, 90 days during any 365 day period (each, a "Registration Default"), then, additional interest shall accrue on the Securities affected thereby over and above the interest rate set forth in the title to the Securities from and including the next day following each such Registration Default, in each case at a rate equal to 0.25% per annum; provided, that the aggregate additional interest will in no event exceed 0.25% per annum. Additional interest attributable to a Registration Default shall cease to accrue once such Registration Default is cured.

2. Registration Under the Securities Act.

(a) Exchange Offer Registration. To the extent not prohibited by any applicable law or applicable interpretation of the staff of the SEC, the Company shall (A) file with the SEC within 90 calendar days after the Closing Date, an Exchange Offer Registration Statement covering the offer by the Company to the Holders to exchange all of the Registrable Securities for Exchange Securities, (B) use its reasonable best efforts to cause such Exchange Offer Registration Statement to be declared effective by the SEC within 180 calendar days after the Closing Date, (C) use its reasonable best efforts to cause such Registration Statement to remain effective until the closing of the Exchange Offer and (D) use its reasonable best efforts to consummate the Exchange Offer within 210 calendar days after the Closing Date. The Exchange Securities will be issued under the Indenture. Upon the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly commence the Exchange Offer, it being the objective of such Exchange Offer to enable each Holder (other than Participating Broker-Dealers) eligible and electing to exchange Registrable Securities for Exchange Securities (assuming that such Holder is not an Affiliate of the Company, acquires the Exchange Securities in the ordinary course of such Holder's business and has no arrangements or understandings with any person to participate in the Exchange Offer for the purpose of distributing the Exchange Securities) to trade such Exchange Securities from and after their receipt without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of a substantial proportion of the several states of the United States.

In connection with the Exchange Offer, the Company shall:

5

(i) mail to each Holder a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(ii) keep the Exchange Offer open for not less than 20 business days (or longer if required by applicable federal and state securities laws) after the date notice thereof is mailed to the Holders;

(iii) use the services of the Depositary for the Exchange Offer with respect to Securities evidenced by global certificates;

(iv) permit Holders to withdraw tendered Registrable Securities at any time prior to 5:00 p.m., New York City time, on the last business day on which the Exchange Offer shall remain open, by sending to the institution specified in the notice, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Securities delivered for exchange, and a statement that such Holder is withdrawing its election to have such Securities exchanged; and

(v) otherwise comply in all material respects with all applicable federal and state securities laws relating to the Exchange Offer.

As soon as practicable after the close of the Exchange Offer, the Company shall:

(i) accept for exchange Registrable Securities duly tendered and not validly withdrawn pursuant to the Exchange Offer in accordance with the terms of the Exchange Offer Registration Statement and the letter of transmittal which is an exhibit thereto;

(ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable Securities so accepted for exchange by the Company; and

(iii) use its reasonable best efforts to cause the Trustee to promptly authenticate and deliver Exchange Securities to each Holder of Registrable Securities equal in principal amount to the principal amount of the Registrable Securities of such Holder so accepted for exchange.

Interest on each Exchange Security will accrue from the last date on which interest was paid on the Registrable Securities surrendered in exchange therefor or, if no interest has been paid on the Registrable Securities, from the Closing Date. The Exchange Offer shall not be subject to any conditions, other than (i) that the Exchange Offer, or the making of any exchange by a Holder, does not violate applicable law or any applicable

6

interpretation of the staff of the SEC, (ii) that no action or proceeding shall have been instituted or threatened in any court or before any governmental agency with respect to the Exchange Offer which, in the judgment of the Company, would reasonably be expected to impair the ability of the Company to proceed with the Exchange Offer, (iii) that no law, rule or regulation or applicable interpretations of the staff of the SEC has been issued or promulgated which, in the good faith determination of the Company, does not permit the Company to effect the Exchange Offer and (iv) that the Holders tender the Registrable Securities to the Company in accordance with the Exchange Offer.

As a condition to participating in the Exchange Offer, each Holder of Registrable Securities (other than Participating Broker-Dealers) who wishes to exchange such Registrable Securities for Exchange Securities in the Exchange Offer shall have represented in writing to the Company that at the time of consummation of the Exchange Offer (i) it is not an Affiliate of the Company or, if it is an Affiliate, it will comply with the registration and prospectus delivery requirements of the Securities Act, to the extent applicable, (ii) any Exchange Securities to be received by it will be acquired in the ordinary course of business, (iii) at the time of the commencement of the Exchange Offer, it has no arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Securities or the Exchange Securities, (iv) it is not acting on behalf of any person who could not truthfully make the foregoing representations and (v) it shall have made such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to render the use of Form S-4 or another appropriate form under the Securities Act available or for the Exchange Offer Registration Statement to be declared effective. To the extent permitted by law, the Company shall inform the Initial Purchasers of the names and addresses of the Holders to whom the Exchange Offer is made and the Initial Purchasers shall have the right to contact such Holders and otherwise facilitate the tender of Registrable Securities in the Exchange Offer.

(b) Shelf Registration.

(i) If, because of any change in law or currently prevailing applicable interpretations thereof by the staff of the SEC, the Company is not permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof, (ii) if for any other reason the Exchange Offer Registration Statement is not declared effective within 180 calendar days following the Closing Date or the Exchange Offer is not consummated within 210 calendar days after the Closing Date (provided that, if the Exchange Offer Registration Statement shall be declared effective after such 180-day period or if the Exchange Offer shall be consummated after such 210-day period, then the Company's obligation under this clause (ii) arising from the failure of the Exchange Offer Registration Statement to be declared effective within such 180-day period or the failure of the Exchange Offer to be consummated within such 210-day period, respectively, shall terminate), (iii) if any Holder (other than an Initial

7

Purchaser) is not eligible to participate in the Exchange Offer or elects to participate in the Exchange Offer but does not receive freely tradeable Exchange Securities pursuant to the Exchange Offer or (iv) upon the written request of any of the Initial Purchasers within 90 days following the consummation of the Exchange Offer with respect to Registrable Securities that are not permitted to be exchanged for Exchange Securities in the Exchange Offer or if the Initial Purchasers do not receive freely tradable Exchange Securities in the Exchange Offer; then, in the case of each of clauses (i) through (iv), the Company shall, at its cost:

(A) as promptly as practicable, but no later than the 30th calendar day after such filing obligation arises, file with the SEC a Shelf Registration Statement relating to the offer and sale of the Registrable Securities by the Holders from time to time in accordance with the methods of distribution elected by the Majority Holders of such Registrable Securities and set forth in such Shelf Registration Statement; provided, that no Holder shall be entitled to have Registrable Securities held by it included in the Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to the Holder and furnishes to the Company in writing such information as the Company may reasonably request for inclusion in the Shelf Registration Statement or any Prospectus included therein;

(B) use its reasonable best efforts to cause such Shelf Registration Statement to be declared effective by the SEC as promptly as practicable; provided that, with respect to Exchange Securities received by a broker-dealer in exchange for any securities that were acquired by such broker-dealer as a result of market-making or other trading activities, the Company may, if permitted by current interpretations by the staff of the SEC, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Regulation S-K Items 507 and/or 508, as applicable, in satisfaction of its obligations under paragraph (A) solely with respect to Participating Broker-Dealers who acquired their Securities as a result of market-making or other trading activities, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement. In the event that the Company is required to file a Shelf Registration Statement upon the request of any Holder (other than an Initial Purchaser) not eligible to participate in the Exchange Offer pursuant to clause (iii) above or upon the request of any Initial Purchaser pursuant to clause (iv) above, the Company shall file and use its reasonable best efforts to have declared effective by the SEC both an Exchange Offer Registration Statement pursuant to Section 2(a) with respect to all Registrable Securities and a Shelf

8

Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by such Holder or such Initial Purchaser, as applicable, after completion of the Exchange Offer;

(C) use its reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required, in order to permit the Prospectus forming part thereof to be usable by Holders, until the earlier of: (i) a period of two years, plus any extensions as provided in Section 2(d)(iii) below, from the date the Shelf Registration Statement is declared effective by the SEC or (ii) such shorter period which will terminate when all of the Registrable Securities covered by the Shelf Registration Statement (a) have been sold pursuant to the Shelf Registration Statement, (b) cease to be outstanding or (c) become eligible for resale pursuant to Rule 144 under the Exchange Act; and

(D) notwithstanding any other provisions hereof, use its reasonable best efforts to ensure that (i) any Shelf Registration Statement and any amendment thereto and any Prospectus forming a part thereof and any supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder,
(ii) any Shelf Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any Prospectus forming part of any Shelf Registration Statement, and any supplement to such Prospectus (as amended or supplemented from time to time), does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in light of the circumstances under which they were made, not misleading; provided, however, clauses (ii) and (iii) shall not apply to any information relating to any Initial Purchaser or any Holder furnished to the Company by or on behalf of such Initial Purchaser or Holder expressly for use in the Shelf Registration Statement.

The Company shall not permit any securities other than the Registrable Securities to be included in the Shelf Registration Statement.

The Company further agrees, if necessary, to supplement or amend the Shelf Registration Statement if reasonably requested in writing by the Majority Holders with respect to information relating to the Holders and otherwise as required by Section 3(b) below, to use its reasonable best efforts to cause any such amendment to become effective and such Shelf Registration Statement to become usable as soon as practicable thereafter and

9

to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

(c) Expenses. The Company shall pay all Registration Expenses in connection with the registration pursuant to Sections 2(a) and 2(b). Each Holder shall pay all expenses of its counsel other than as provided for in this Agreement, and underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder's Registrable Securities pursuant to a Shelf Registration Statement.

(d) Effective Registration Statement.

(i) The Company shall be deemed not to have used its reasonable best efforts to cause the Exchange Offer Registration Statement or the Shelf Registration Statement, as the case may be, to become, or to remain, effective during the requisite periods set forth herein if the Company voluntarily takes any action that could reasonably be expected to result in any such Registration Statement not being declared effective or remaining effective or in the Holders of Registrable Securities covered thereby not being able to exchange or offer and sell such Registrable Securities during that period unless (A) such action is required by applicable law or (B) such action is taken by the Company in good faith and for valid business reasons (but not including avoidance of the Company's obligations hereunder), including the acquisition or divestiture of assets or a material corporate transaction or event so long as the Company promptly complies with the requirements of Section 3(k) hereof, if applicable.

(ii) An Exchange Offer Registration Statement pursuant to
Section 2(a) hereof or a Shelf Registration Statement pursuant to
Section 2(b) hereof shall not be deemed to have become effective unless it has been declared effective by the SEC; provided, however, that if, after it has been declared effective, the offering of Registrable Securities pursuant to a Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other applicable governmental agency or court, such Registration Statement shall be deemed not to have been effective during the period of such interference, until the offering of Registrable Securities pursuant to such Registration Statement may legally resume.

(iii) During any 365-day period, the Company may suspend the availability of a Shelf Registration Statement and the use of the related Prospectus, as provided in Section 3(e)(vi), for up to four periods of up to 45 consecutive days (except for the consecutive 45-day period immediately prior to maturity of the Securities), but no more than an aggregate of 90 days during any 365-day period, if any event shall occur (A) as set forth in Section 2(d)(i) or (B) that, in the reasonable good faith

10

determination of the Company, in accordance with its understanding of the disclosure requirements of applicable securities law based on advice of counsel, would require disclosure of any financing, acquisition, corporate reorganization or other transaction or development involving the Company or one of its Affiliates that is or would be material to the Company and that, in the reasonable judgment of the Company, such disclosure would not at that time be in the best interests of the Company (a "Material Event Election"), provided that any period during which the Company requires Holders to refrain from disposing of their Registrable Securities due to a Material Event Election (an "Election Period") shall be deemed to trigger the obligation of the Company to pay additional interest in accordance with Section 2(e) to the extent that such Election Period, together with all other days that the Shelf Registration Statement has become unusable in any consecutive twelve-month period, exceeds 90 days in the aggregate. The two-year period provided for in Section 2(b)(i)(C) above shall be extended by an amount of time equal to all such Election Periods.

(e) Increase in Interest Rate. The Indenture provides that in the event that (i) the Exchange Offer Registration Statement is not filed with the SEC on or prior to the 90th calendar day after the Closing Date, (ii) the Exchange Offer Registration Statement is not declared effective on or prior to the 180th calendar day after the Closing Date, (iii) the Exchange Offer is not consummated on or prior to the 210th calendar day following the Closing Date, or (iv) if required, a Shelf Registration Statement with respect to the Registrable Securities is not filed with the SEC on or prior to the 30th calendar day after such filing obligation arises or is not declared effective on or prior to the 45th calendar day after the filing thereof, or (v) the Election Periods exceed, in the aggregate, 90 days during any 365 day period (each, a "Registration Default"), the per annum interest rate borne by the Registrable Securities affected thereby shall be increased by one-quarter of one percent (0.25%) per annum following a Registration Default; provided that the maximum aggregate additional interest with respect to the Registrable Securities may in no event exceed one-quarter of one percent (0.25%) per annum. Upon (w) the filing of the Exchange Offer Registration Statement after the 90 day period described in clause (i) above, (x) the effectiveness of the Exchange Offer Registration Statement after the 180-day period described in clause (ii) above, (y) the consummation of the Exchange Offer after the 210-day period described in clause (iii) above, or (z) the filing or effectiveness of a Shelf Registration Statement after the applicable period described in clause (iv) above, the interest rate borne by the Registrable Securities from the date of such filing, effectiveness or consummation, as the case may be, shall be reduced to the original interest rate if the Company is otherwise in compliance with this paragraph; provided, however, that, if after any such reduction in interest rate, a different Registration Default occurs, the interest rate shall again be increased pursuant to the foregoing provisions. No increase in the rate under clause (i), (ii) or (iii) above shall be payable for any period during which a Shelf Registration is effective.

(f) Specific Enforcement. Without limiting the remedies available to the Initial

11

Purchasers and the Holders, the Company acknowledges that any failure by the Company to comply with its obligations under Sections 2(a) and 2(b) hereof may result in irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Sections 2(a) and 2(b).

3. Registration Procedures. In connection with the obligations of the Company with respect to the Registration Statements pursuant to Sections 2(a) and 2(b) hereof, the Company shall:

(a) prepare and file with the SEC a Registration Statement, within the relevant time periods specified in Section 2, on the appropriate form under the Securities Act, which form shall (i) be selected by the Company,
(ii) in the case of a Shelf Registration Statement, be available for the sale of the Registrable Securities by the selling Holders thereof and

12

Registrable Securities in connection with the offering and sale of the Registrable Securities covered by the Prospectus or any amendment or supplement thereto;

(d) use its reasonable best efforts to register or qualify the Registrable Securities under all applicable state securities or "blue sky" laws of such jurisdictions as any Holder of Registrable Securities covered by a Registration Statement and each underwriter of an underwritten offering of Registrable Securities shall reasonably request by the time the applicable Registration Statement is declared effective by the SEC or shortly thereafter, keep each such registration or qualification effective during the period such Registration Statement is required to be effective or until all of such Registrable Securities are sold, whichever is shortest, and do any and all other acts and things which may be reasonably necessary or advisable to enable such Holder to consummate the disposition in each such jurisdiction of such Registrable Securities owned by such Holder; provided, however, that the Company shall not be required to (i) qualify as a foreign corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d) or (ii) take any action which would subject it to general service of process or taxation in any such jurisdiction;

(e) in the case of a Shelf Registration, promptly notify each Holder of Registrable Securities included in the Shelf Registration and one counsel for such Holders and, if requested by such Holder or counsel, confirm such advice in writing promptly (i) when a Registration Statement has become effective and when any post-effective amendments and supplements thereto become effective, (ii) of any request by the SEC or any state securities authority for post-effective amendments and supplements to a Registration Statement and Prospectus or for additional information after the Registration Statement has become effective, (iii) of the issuance by the SEC or any state securities authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, (iv) between the effective date of a Registration Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of the Company contained in any underwriting agreement, securities sales agreement or other similar agreement, if any, relating to such offering cease to be true and correct in all material respects, (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (vi) of the happening of any event or the discovery of any facts during the period a Shelf Registration Statement is effective (including as contemplated in Section 2(d)(iii) hereof) which (A) is contemplated in
Section 2(d)(i) or (B) makes any statement made in such Shelf Registration Statement or the related Prospectus untrue in any material respect or which requires the making of any changes in such Shelf Registration Statement or Prospectus in order to make the statements therein not misleading and (vii) of any determination by the Company that a post-effective amendment to a Registration Statement is necessary;

(f) (A) in the case of an Exchange Offer Registration Statement, (i) include in the Exchange Offer Registration Statement a "Plan of Distribution" section covering the use of the Prospectus included in the Exchange Offer Registration Statement by broker-dealers who have exchanged their Registrable Securities for Exchange Securities for the resale of such Exchange Securities, (ii) furnish to each broker-dealer who has delivered to the Company a notice in writing and who desires to participate in the Exchange Offer, without charge, as many copies of each Prospectus included in the Exchange Offer Registration Statement, including any preliminary prospectus, and any amendment or supplement thereto, as such broker-dealer may reasonably request, (iii) include in the Exchange Offer Registration Statement a statement that any broker-dealer who holds Registrable Securities acquired for its own account as a result of market-making activities or other trading activities (a "Participating Broker-Dealer"), and who receives Exchange Securities for Registrable Securities pursuant to the Exchange Offer, may be deemed a statutory underwriter and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities, (iv) subject to the last paragraph of this
Section 3, hereby consent to the use of the Prospectus forming part of the Exchange Offer Registration Statement or any amendment or supplement thereto, by any broker-dealer in connection with the sale or transfer of the Exchange Securities covered by the Prospectus or any amendment or supplement thereto, provided such Person has provided the Company in writing with any information required by Item 507 of Regulation S-K (or any similar provision then in force) for inclusion in the prospectus contained in the Exchange Offer Registration Statement, and (v) include in the transmittal letter or similar documentation to be executed by an exchange offeree in order to participate in the Exchange Offer the following provision:

"If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Exchange Securities. If the undersigned is a broker-dealer that will receive Exchange Securities for its own account in exchange for Registrable Securities, it represents that the Registrable Securities to be exchanged for Exchange Securities were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities pursuant to the Exchange Offer; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act;"

(B) to the extent any Participating Broker-Dealer participates in the Exchange Offer, the Company shall use its reasonable best efforts to cause to be delivered at the request of an entity representing the Participating Broker-Dealers (which entity shall be Salomon Smith Barney Inc., unless it elects not to act as such representative) any "cold comfort" letters with respect to the Prospectus in the form existing on the last date for which

14

exchanges are accepted pursuant to the Exchange Offer and with respect to each subsequent amendment or supplement, if any, effected during the period specified in clause (C) below;

(C) to the extent any Participating Broker-Dealer participates in the Exchange Offer, the Company shall use its reasonable best efforts to maintain the effectiveness of the Exchange Offer Registration Statement for a period of 180 days following the closing of the Exchange Offer or such shorter period which will terminate when the Participating Broker-Dealers have completed all resales subject to applicable prospectus delivery requirements; and

(D) the Company shall not be required to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement as would otherwise be contemplated by Section 3(b) hereof, or take any other action as a result of this Section 3(f), for a period exceeding 90 days after the last date for which exchanges are accepted pursuant to the Exchange Offer (as such period may be extended by the Company) and Participating Broker-Dealers shall not be authorized by the Company to, and shall not, deliver such Prospectus after such period in connection with resales contemplated by this Section 3;

(k) in the case of a Shelf Registration, upon the occurrence of any event or the

15

discovery of any facts, each as contemplated by Section 3(e)(vi) hereof, use its reasonable best efforts to prepare a supplement or post-effective amendment to a Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will not contain at the time of such delivery any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company agrees to notify each Holder to suspend use of the Prospectus as promptly as practicable after the occurrence of such an event, and each Holder hereby agrees to suspend use of the Prospectus until the Company has amended or supplemented the Prospectus to correct such misstatement or omission. At such time as such public disclosure is otherwise made or the Company determines that such disclosure is not necessary, in each case to correct any misstatement of a material fact or to include any omitted material fact, the Company agrees promptly to notify each Holder of such determination and to furnish each Holder such numbers of copies of the Prospectus, as amended or supplemented, as such Holder may reasonably request;

(l) use its reasonable best efforts to obtain CUSIP numbers for all Exchange Securities, or Registrable Securities, as the case may be, not later than the effective date of a Registration Statement, and provide the Trustee with printed certificates for the Exchange Securities or Registrable Securities, as the case may be, in a form eligible for deposit with the Depositary;

(m) in the case of a Shelf Registration, enter into agreements (including underwriting agreements) and take all other customary and appropriate actions (including those reasonably requested by the Majority Holders of the Registrable Securities) in order to expedite or facilitate the disposition of such Registrable Securities and in such connection, whether or not an underwriting agreement is entered into and whether or not the registration is an underwritten registration, in a manner that is reasonable and customary:

(i) make such representations and warranties to the Holders of such Registrable Securities and the underwriters, if any, in form, substance and scope as are customarily made by the Company to underwriters in similar underwritten offerings as may be reasonably requested by such Holders and underwriters;

(ii) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriters, if any, and the Holders of a majority in principal amount of the Registrable Securities being sold) addressed to each selling Holder and the underwriters, if any, covering the matters customarily covered in opinions requested in sales of securities or underwritten offerings;

16

(iii) obtain "cold comfort" letters and updates thereof from the Company's independent certified public accountants addressed to the underwriters, if any, and will use reasonable best efforts to have such letters addressed to the selling Holders of Registrable Securities, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters to underwriters in connection with similar underwritten offerings;

(iv) enter into a securities sales agreement with the Holders and an agent of the Holders providing for, among other things, the appointment of such agent for the selling Holders for the purpose of soliciting purchases of Registrable Securities, which agreement shall be in form, substance and scope customary for similar offerings by the Company;

(v) if an underwriting agreement is entered into in the case of an underwritten offering, cause the same to set forth indemnification provisions and procedures substantially equivalent to the indemnification provisions and procedures set forth in
Section 5 hereof with respect to the underwriters and all other parties to be indemnified pursuant to Section 5 hereof; and

(vi) deliver such documents and certificates as may be reasonably requested by the underwriters or the Holders and as are customarily delivered in similar offerings by the Company.

The above shall be done at (i) the effectiveness of such Registration Statement (and, if reasonably requested in writing by the Majority Holders), each post-effective amendment thereto) and (ii) each closing under any underwriting or similar agreement as and to the extent required thereunder. In the case of any underwritten offering, the Company shall provide written notice to the Holders of all Registrable Securities of such underwritten offering at least 10 days prior to the filing of a prospectus supplement for such underwritten offering. Such notice shall
(x) offer each such Holder the right to participate in such underwritten offering, (y) specify a date, which shall be no earlier than 10 days following the date of such notice, by which such Holder must inform the Company of its intent to participate in such underwritten offering and (z) include the instructions such Holder must follow in order to participate in such underwritten offering;

(o) in the case of a Shelf Registration, make available for inspection by representatives of the Holders of the Registrable Securities and any underwriters participating in any disposition pursuant to a Shelf Registration Statement and any U.S. counsel or accountant retained by such Holders or underwriters, all financial and other records and pertinent corporate documents of the Company reasonably requested by any such Persons, and cause the officers, employees and any other agents of the Company to supply all information reasonably requested by any such representative, underwriter, special counsel

17

or accountant in connection with a Registration Statement; provided that any such records, documents and such information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such records, documents or information shall be kept confidential by any such representative, underwriter, counsel or accountant and shall be used only in connection with such Shelf Registration Statement, unless such information has become available (not in violation or breach of this Agreement) to the public generally or through a third party without an accompanying obligation of confidentiality, and except that such representative, underwriter, counsel or accountant shall have no liability, and shall not be in breach of this provision, if disclosure of such confidential information is made in connection with a court proceeding or required by law, and the Company shall be entitled to request that such representative, underwriter, counsel or accountant sign a confidentiality agreement to the foregoing effect. Each such person will be required to agree that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company unless and until such is made generally available to the public through no fault or action of such person. Each selling Holder of such Registrable Securities will be required to further agree that it will, upon learning that disclosure of confidential information is necessary, give notice to the Company to allow the Company at its expense to undertake appropriate action to prevent disclosure of the confidential information;

(p) (i) in the case of an Exchange Offer, within a reasonable time prior to the filing of any Exchange Offer Registration Statement, any Prospectus forming a part thereof, any amendment to an Exchange Offer Registration Statement or amendment or supplement to a Prospectus, provide copies of such document to the Initial Purchasers, and make such changes in any such document prior to the filing thereof as the Initial Purchasers or their counsel may reasonably request; (ii) in the case of a Shelf Registration, a reasonable time prior to filing any Shelf Registration Statement, any Prospectus forming a part thereof, any amendment to such Shelf Registration Statement or amendment or supplement to such Prospectus, provide copies of such document to the Holders of Registrable Securities, to the Initial Purchasers, to counsel on behalf of the Holders and to the underwriter or underwriters of an underwritten offering of Registrable Securities, if any, and make such changes in any such document prior to the filing thereof as counsel to the Initial Purchasers, the Holders or any underwriter may reasonably request; and (iii) cause the representatives of the Company to be available for discussion of such document as shall be reasonably requested by the Holders of Registrable Securities, the Initial Purchasers on behalf of such Holders or any underwriter, and shall not at any time make any filing of any such document of which such Holders, the Initial Purchasers on behalf of such Holders, their counsel or any underwriter shall not have previously been advised and furnished a copy or to which such Holders, the Initial Purchasers on behalf of such Holders, their counsel or any underwriter shall reasonably object within a reasonable time period;

(q) in the case of a Shelf Registration, use its reasonable best efforts to cause the

18

Registrable Securities to be rated with at least one "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g)(2) under the Securities Act), if so requested by the Majority Holders or by the underwriter or underwriters of an underwritten offering, unless the Registrable Securities are already so rated;

(r) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC and make available to its security holders, as soon as reasonably practicable, an earnings statement covering at least twelve (12) months which shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder; and

(s) cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by any underwriter and its counsel.

In the case of a Shelf Registration Statement, the Company may (as a condition to such Holder's participation in the Shelf Registration) require each Holder of Registrable Securities to furnish to the Company or its counsel such information regarding such Holder and the proposed distribution by such Holder of such Registrable Securities, as the Company may from time to time reasonably request, and agree in writing to be bound by the Agreement, including the indemnification provisions.

In the case of a Shelf Registration Statement, each Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts, each of the kind described in Sections 2(d)(i) and 3(e)(ii)-(vii) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement until such Holder's receipt of (i) the copies of the supplemented or amended Prospectus contemplated by Section 3(k) hereof or (ii) written notice from the Company that the Shelf Registration Statement is once again effective and that no supplement or amendment is required. If so directed by the Company, such Holder will deliver to the Company (at the Company's expense) all copies in the Holder's possession, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.

If the Company shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Shelf Registration Statement as a result of the happening of any event or the discovery of any facts, each of the kind described in Sections 2(d)(i) and 3(e)(vi) hereof, the Company shall be deemed to have used its reasonable best efforts to keep the Shelf Registration Statement effective during such period of suspension; provided that (i) such period of suspension shall not exceed the time periods provided in Section 2(d)(iii) hereof and (ii) the Company shall, if necessary, use its reasonable best efforts to file and have declared effective (if an amendment) as soon as practicable an amendment or supplement to the Shelf Registration Statement and shall extend the period during which the Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders shall have received copies of the supplemented or amended

19

Prospectus necessary to resume such dispositions.

4. Underwritten Registrations. If any of the Registrable Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Majority Holders of such Registrable Securities included in such offering and shall be reasonably acceptable to the Company.

No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

5. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Initial Purchaser, each Holder, including Participating Broker-Dealers, each underwriter who participates in an offering of Registrable Securities, their respective Affiliates, and their respective directors, officers, employees, agents, and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any properly documented out-of-pocket legal or other expenses reasonably incurred by the Initial Purchaser, any Holder or any such controlling or affiliated Person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any amendment thereof, pursuant to which Exchange Securities or Registrable Securities were registered under the Securities Act, including all documents incorporated therein by reference, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or caused by any untrue statement or alleged untrue statement of a material fact contained in any Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Initial Purchaser any Holder or underwriter furnished to the Company in writing by or on behalf of such Initial Purchaser or by or relating to any Holder or underwriter who participates in an offering of Registrable Securities, in each case expressly for use therein.

20

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, each Initial Purchaser, each underwriter who participates in an offering of Registrable Securities, and the other selling Holders, and each of their respective Affiliates and directors, officers (including each director and officer of the Company who signed the Registration Statement) employees and agents and each Person, if any, who controls the Company, any Initial Purchaser, any underwriter or any other selling Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses described in the indemnity contained in Section 5(a), as incurred), but only with reference to information relating to such Holder furnished to the Company in writing by or on behalf of such Holder expressly for use in any Registration Statement or any amendment thereof or any Prospectus or any amendments or supplements thereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any Person in respect of which indemnity may be sought pursuant to either paragraph (a) or paragraph (b) above, such Person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing (but the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party except to the extent it is materially prejudiced or harmed) and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (a) (if the indemnifying party is the Company) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Initial Purchasers and all Persons, if any, who control any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, (b) (if the indemnifying party is a Holder) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and all Persons, if any, who control the Company within the meaning of either such Section and (c) (if the indemnifying party is the Company) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Holders and all Persons, if any, who control any Holders within the

21

meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Initial Purchasers and such control Persons of the Initial Purchasers, such firm shall be designated in writing by Salomon Smith Barney Inc. In the case of any such separate firm for the Holders and such Persons who control Holders, such firm shall be designated in writing by the Majority Holders. In all other cases, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding affected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in paragraph (a) or paragraph (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of such indemnifying party or parties on the one hand and the indemnified party or parties on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or parties or such indemnified party or parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The obligations of the Initial Purchasers and the Holders of Registrable Securities to contribute pursuant to this Section 5 are several in proportion to the respective number of Securities

22

have purchased hereunder, and not joint.

(e) The Company, the Initial Purchasers, and each Holder of Registrable Securities agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any out-of-pocket legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5, no Holder shall be required to indemnify or contribute any amount in excess of the amount by which the total price at which Registrable Securities were sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5, each Person, if any, who controls an Initial Purchaser or Holder or underwriter within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser or Holder or underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each Person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Initial Purchaser or any Holder or underwriter, or any Person controlling any Initial Purchaser or any Holder or underwriter, or by or on behalf of the Company, its officers or directors or any Person controlling the Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

6. Miscellaneous.

(a) Rule 144 and Rule 144A. For so long as the Company is subject to the reporting requirements of Section 13 or 15 of the Exchange Act, the Company covenants that it will file the reports required to be filed by it under Section 13(a) or 15(d) of the Exchange Act and the rules and regulations adopted by the SEC thereunder, that if it ceases to be so required to file such reports, it will upon the request of any Holder of Registrable Securities

23

(i) make publicly available or cause to be made publicly available such information as is necessary to permit sales pursuant to Rule 144 under the Securities Act, (ii) deliver or cause to be delivered such information to a prospective purchaser as is necessary to permit sales pursuant to Rule 144A under the Securities Act and it will take such further action as any Holder of Registrable Securities may reasonably request, and (iii) take such further action that is reasonable in the circumstances, in each case, to the extent required from time to time to enable such Holder to sell its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 under the Securities Act, as such rule may be amended from time to time, (y) Rule 144A under the Securities Act, as such rule may be amended from time to time, or (z) any similar rules or regulations hereafter adopted by the SEC. Upon the written request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements.

(b) No Inconsistent Agreements. The Company has not entered into nor will the Company on or after the date of this Agreement enter into any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's other issued and outstanding securities under any such agreements.

(c) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the material provisions hereof may not be given unless the Company has obtained the written consent of the Majority Holders of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or departure.

(d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder (other than an Initial Purchaser), at the most current address set forth on the records of the Registrar under the Indenture, (ii) if to an Initial Purchaser, at the most current address given by such Initial Purchaser to the Company by means of a notice given in accordance with the provisions of this Section 6(d), which address initially is the address set forth in the Purchase Agreement; and (iii) if to the Company, initially at its addresses set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 6(d).

All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five business days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if telecopied; and on the

24

next business day if timely delivered to an air courier guaranteeing overnight delivery.

Copies of all such notices, demands, or other communications shall be concurrently delivered by the Person giving the same to the Trustee, at the address specified in the Indenture.

(e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms hereof or of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities, such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement, including the restrictions on resale set forth in this Agreement and, if applicable, the Purchase Agreement, and such Person shall be entitled to receive the benefits hereof.

(f) Third Party Beneficiary. The Holders shall be third party beneficiaries to the agreements made hereunder between the Company and the Initial Purchasers and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of Holders hereunder.

(g) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(h) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(i) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of laws provisions.

(j) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired thereby.

Ladies and Gentlemen:

This opinion is being rendered to you in connection with the proposed registration by The Dow Chemical Company (the "Company") of $1,000,000,000 in aggregate principal amount of the Company's 5-1/4% Notes due 2004 (the "Exchange Securities"), pursuant to a registration statement on Form S-4 to be filed with the Securities and Exchange Commission (the "Commission") on the date hereof, under the Securities Act of 1933, as amended (the "Act") (such registration statement, as amended or supplemented, is hereinafter referred to as the "Registration Statement"). The Exchange Securities are to be issued pursuant to an Indenture, dated as of April 1, 1992, between the Company and Bank One Trust Company, N.A., as successor in interest to The First National Bank of Chicago, as trustee, 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 (as so supplemented, the "Indenture"). The Exchange Securities are to be issued in exchange for and in replacement of the Company's outstanding $1,000,000,000 aggregate principal amount of 5-1/4% Notes due 2004 (the "Original Securities").

In rendering the opinions expressed herein, we have examined (i) the Registration Statement, (ii) the Indenture and (iii) the Registration Rights Agreement, dated as of May 15, 2001, among the Company and the Initial Purchasers named therein. In addition, we have examined such corporate and other records, instruments, certificates and documents and have made such further investigation as we have deemed necessary or appropriate for the purposes of the opinions expressed below.

In expressing the opinions set forth below, we have assumed the genuineness of all signatures, the conformity to the originals of all documents reviewed by us as copies, the authenticity and completeness of all original documents reviewed by us in original or copy form and the legal competence of each individual executing any document. As to all parties other than

the Company, we have assumed the due authorization, execution and delivery of all documents and the validity and enforceability thereof against all parties thereto, other than the Company, in accordance with their respective terms. As to any facts material to the opinions expressed herein which we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials.

Based upon and subject to the foregoing, and having regard for legal considerations which we deem relevant, we are of the opinion that when (i) the Registration Statement becomes effective, (ii) the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and (iii) the Exchange Securities have been duly executed and authenticated in accordance with the provisions of the Indenture and duly delivered to the purchasers thereof in exchange for the Original Securities, the Exchange Securities will be validly issued and binding obligations of the Company, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general applicability relating to or affecting creditors' rights and to general equitable principles.

We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. We also consent to the reference to our firm under the heading "Legal Matters" in the related prospectus. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

We are admitted to practice in the States of Illinois and New York and our opinions expressed herein are limited solely to the federal laws of the United States of America, the laws of the States of Illinois and New York and the General Corporation Law of the State of Delaware, and we express no opinion herein concerning the laws of any other jurisdiction.

The opinions and statements expressed herein are as of the date hereof. We assume no obligation to update or supplement this opinion letter to reflect any facts or circumstances that may hereafter come to our attention or any changes in applicable law which may hereafter occur.

Very truly yours,

MAYER, BROWN & PLATT

Delivery of this instrument to an address other than as set forth above, or transmission of instructions via facsimile other than as set forth above, will not constitute a valid delivery.

The undersigned acknowledges that he or she has received the Prospectus, dated o, 2001 (the "Prospectus"), of The Dow Chemical Company, a Delaware corporation (the "Company"), and this Letter of Transmittal (the "Letter"), which together constitute the Company's offer (the "Exchange Offer") to exchange an aggregate principal amount of up to $1,000,000,000 of the Company's 5-1/4% Notes due 2004 (the "Exchange Notes") which have been registered under the Securities Act of 1933, as amended (the "Securities Act"), for a like principal amount of the Company's issued and outstanding 5-1/4% Notes due 2004 (the "Original Notes") from the registered holders thereof (the "Holders").

For each Original Note accepted for exchange, the Holder of such 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 or, if no interest has been paid on the Original Notes, from May 15, 2001. Accordingly, registered Holders of Exchange Notes on the relevant record date for the first interest payment date following the consummation of the Exchange Offer will receive


interest accruing from the most recent date to which interest has been paid or, if no interest has been paid, from May 15, 2001. Original Notes accepted for exchange will cease to accrue interest from and after the date of consummation of the Exchange Offer.

Tenders by book-entry transfer may also be made by delivering an Agent's Message in lieu of this Letter. The term "Agent's Message" means a message, transmitted by the Book-Entry Transfer Facility to, and received by, the Exchange Agent and forming a part of a Book-Entry Confirmation (as defined below), which states that the Book-Entry Transfer Facility has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by this Letter and that the Company may enforce this Letter against such participant. Holders of Original Notes whose certificates are not immediately available, or who are unable to deliver their certificates or confirmation of the book-entry tender of their Original Notes into the Exchange Agent's account at the Book-Entry Transfer Facility (a "Book-Entry Confirmation") and all other documents required by this Letter to the Exchange Agent on or prior to the Expiration Date, must tender their Original Notes according to the guaranteed delivery procedures set forth in "The Exchange Offer--Guaranteed Delivery Procedures" section of the Prospectus. See Instruction 1.

Delivery of documents to the Book Entry Transfer Facility does not constitute delivery to the Exchange Agent.

The undersigned has completed the appropriate boxes below and signed this Letter to indicate the action the undersigned desires to take with respect to the Exchange Offer.

List below the Original Notes to which this Letter relates. If the space provided below is inadequate, the certificate numbers and principal amount of Original Notes should be listed on a separate signed schedule affixed hereto.

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to the Company the aggregate principal amount of Original Notes indicated above. Subject to, and effective upon, the acceptance for exchange of the Original Notes tendered hereby, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Company all right, title and interest in and to such Original Notes as are being tendered hereby.

The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the undersigned's true and lawful agent and attorney-in-fact with respect to such tendered Original Notes, with full power of substitution, among other things, to cause the Original Notes to be assigned, transferred and exchanged. The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Original Notes, and to acquire Exchange Notes issuable upon the exchange of such tendered Original Notes, and that, when the same are accepted for exchange, the Company will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim when the same are accepted by the Company. The undersigned hereby further represents that any Exchange Notes acquired in exchange for Original Notes tendered hereby will have been acquired in the ordinary course of business of the person receiving such Exchange Notes, whether or not such person is the undersigned, that neither the Holder of such Original Notes nor any such other person is participating in, intends to participate in or has an arrangement or understanding with any person to participate in the distribution of such Exchange Notes and that neither the Holder of such Original Notes nor any such other person is an "affiliate," as defined in Rule 405 under the Securities Act, of the Company.

The undersigned acknowledges that this Exchange Offer is being made in reliance on interpretations by the staff of the Securities and Exchange Commission (the "SEC"), as set forth in no-action letters issued to third parties, that the Exchange Notes issued pursuant to the Exchange Offer in exchange for the Original Notes may be offered for resale, resold and otherwise transferred by Holders thereof (other than any such Holder that is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Exchange Notes are acquired in the ordinary course of such Holders' business and such Holders have no arrangement with any person to participate in the distribution of such Exchange Notes. However, the SEC has not considered the Exchange Offer in the context of a no-action letter and there can be no assurance that the staff of the SEC would make a similar determination with respect to the Exchange Offer as in other circumstances. If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of Exchange Notes and has no arrangement or understanding to participate in a distribution of Exchange Notes. If any Holder is an affiliate of the Company, is engaged in or intends to engage in or has any arrangement or understanding with respect to the distribution of the Exchange Notes to be acquired pursuant to the Exchange Offer, such Holder (i) could not rely on the applicable interpretations of the staff of the SEC and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. If the undersigned is a broker-dealer that will receive Exchange Notes for its own account in exchange for Original Notes, it represents that the Original Notes to be exchanged for the Exchange Notes were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

The undersigned will, upon request, execute and deliver any additional documents deemed by the Company to be necessary or desirable to complete the sale, assignment and transfer of the Original Notes tendered hereby. All authority conferred or agreed to be conferred in this Letter and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned. This tender may be withdrawn only in accordance with the procedures set forth in "The Exchange Offer--Withdrawal Rights" section of the Prospectus.

Unless otherwise indicated herein in the box entitled "Special Issuance Instructions" below, please deliver the Exchange Notes (and, if applicable, substitute certificates representing Original Notes for any Original Notes not


exchanged) in the name of the undersigned or, in the case of a book-entry delivery of Original Notes, please credit the account indicated above maintained at the Book-Entry Transfer Facility. Similarly, unless otherwise indicated under the box entitled "Special Delivery Instructions" below, please send the Exchange Notes (and, if applicable, substitute certificates representing Original Notes for any Original Notes not exchanged) to the undersigned at the address shown above in the box entitled "Description of Original Notes."

The undersigned, by completing the box entitled "Description of Original Notes" above and signing this letter, will be deemed to have tendered the Original Notes as set forth in such box above.

INSTRUCTIONS

Forming Part of the Terms and Conditions of the Exchange Offer

1. Deliver of this Letter and Notes; Guaranteed Delivery Procedures.

This Letter is to be completed by holders of Original Notes either if certificates are to be forwarded herewith or if tenders are to be made pursuant to the procedures for delivery by book-entry transfer set forth in "The Exchange Offer--Book-Entry Transfer" section of the Prospectus and an Agent's Message is not delivered. Tenders by book-entry transfer may also be made by delivering an Agent's Message in lieu of this Letter. The term "Agent's Message" means a message, transmitted by the Book-Entry Transfer Facility to and received by the Exchange Agent and forming a part of a Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by the Letter of Transmittal and that the Company may enforce the Letter of Transmittal against such participant. Certificates for all physically tendered Original Notes, or Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed Letter (or manually signed facsimile hereof or Agent's Message in lieu thereof) and any other documents required by this Letter, must be received by the Exchange Agent at the address set forth herein on or prior to the Expiration Date, or the tendering holder must comply with the guaranteed delivery procedures set forth below. Original Notes tendered hereby must be in denominations of principal amount of $1,000 and any integral multiple thereof.

Holders whose certificates for Original Notes are not immediately available or who cannot deliver their certificates and all other required documents to the Exchange Agent on or prior to the Expiration Date, or who cannot complete the procedure for book-entry transfer on a timely basis, may tender their Original Notes pursuant to the guaranteed delivery procedures set forth in "The Exchange Offer--Guaranteed Delivery Procedures" section of the Prospectus. Pursuant to such procedures, (i) such tender must be made through an Eligible Institution (as defined below), (ii) prior to 5:00 P.M., New York City time, on the Expiration Date, the Exchange Agent must receive from such Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by the Company (by facsimile transmission, mail or hand delivery), setting forth the name and address of the holder of Original Notes and the amount of Original Notes tendered, stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange ("NYSE") trading days after the date of execution of the Notice of Guaranteed Delivery, the certificates for all physically tendered Original Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees and any other documents required by this Letter will be deposited by the Eligible Institution with the Exchange Agent, and (iii) the certificates for all physically tendered Original Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees and all other documents required by this Letter, are received by the Exchange Agent within three NYSE trading days after the date of execution of the Notice of Guaranteed Delivery.

The method of delivery of this Letter, the Original Notes and all other required documents is at the election and risk of the tendering holders, but the delivery will be deemed made only when actually received or confirmed by the Exchange Agent. If Original Notes are sent by mail, it is suggested that the mailing be registered mail, properly insured, with return receipt requested, made sufficiently in advance of the Expiration Date to permit delivery to the Exchange Agent prior to 5:00 P.M., New York City time, on the Expiration Date.

See "The Exchange Offer" section of the Prospectus.

2. Partial Tenders (Not Applicable to Noteholders Who Tender by Book-Entry Transfer).

If less than all of the Original Notes evidenced by a submitted certificate are to be tendered, the tendering holder(s) should fill in the aggregate principal amount of Original Notes to be tendered in the box above entitled "Description of Original Notes--Principal Amount Tendered." A reissued certificate representing the balance of nontendered Original Notes will be sent to such tendering holder, unless otherwise provided in the appropriate box on this Letter, promptly after the Expiration Date. All of the Original Notes


delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated.

3. Signatures on this Letter, Bond Powers and Endorsements, Guarantee of Signatures.

If this Letter is signed by the registered holder of the Original Notes tendered hereby, the signature must correspond exactly with the name as written on the face of the certificates without any change whatsoever.

If any tendered Original Notes are owned of record by two or more joint owners, all of such owners must sign this Letter.

If any tendered Original Notes are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are different registrations of certificates.

When this Letter is signed by the registered holder or holders of the Original Notes specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required. If, however, the Exchange Notes are to be issued, or any untendered Original Notes are to be reissued, to a person other than the registered holder, then endorsements of any certificates transmitted hereby or separate bond powers are required. Signatures on such certificate(s) must be guaranteed by an Eligible Institution.

If this Letter is signed by a person other than the registered holder or holders of any certificate(s) specified herein, such certificate(s) must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name or names of the registered holder or holders appear(s) on the certificate(s) and signatures on such certificate(s) must be guaranteed by an Eligible Institution.

If this Letter or any certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by the Company, proper evidence satisfactory to the Company of their authority to so act must be submitted.

Endorsements on certificates for Original Notes or signatures on bond powers required by this Instruction 3 must be guaranteed by a firm that 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 (each an "Eligible Institution").

Signatures on this Letter need not be guaranteed by an Eligible Institution, provided the Original Notes are tendered: (i) by a registered holder of Original Notes (which term, for purposes of the Exchange Offer, includes any participant in the Book-Entry Transfer Facility system whose name appears on a security position listing as the holder of such Original Notes) who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on this Letter, or (ii) for the account of an Eligible Institution.

4. Special Issuance and Delivery Instructions.

Tendering holders of Original Notes should indicate in the applicable box the name and address to which Exchange Notes issued pursuant to the Exchange Offer and or substitute certificates evidencing Original Notes not exchanged are to be issued or sent, if different from the name or address of the person signing this Letter. In the case of issuance in a different name, the employer identification or social security number of the person named must also be indicated. Noteholders tendering Original Notes by book-entry transfer may request that Original Notes not exchanged be credited to such account maintained at the Book-Entry Transfer Facility as such noteholder may designate hereon. If no such instructions are given, such Original Notes not exchanged will be returned to the name and address of the person signing this Letter.

5. Taxpayer Identification Number.

Federal income tax law generally requires that a tendering holder whose Original Notes are accepted for exchange must provide the Company (as payor) with such holder's correct Taxpayer Identification Number ("TIN") on Substitute Form W-9 below, which in the case of a tendering holder who is an individual, is his or


her social security number. If the Company is not provided with the current TIN or an adequate basis for an exemption from backup withholding, such tendering holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, the Exchange Agent may be required to withhold 31% of the amount of any reportable payments made after the exchange to such tendering holder of Exchange Notes. If withholding results in an overpayment of taxes, a refund may be obtained.

Exempt holders of Original Notes (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. See the enclosed Guidelines of Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for additional instructions.

To prevent backup withholding, each tendering holder of Original Notes must provide its correct TIN by completing the Substitute Form W-9 set forth below, certifying, under penalties of perjury, that the TIN provided is correct (or that such holder is awaiting a TIN) and that (i) the holder is exempt from backup withholding, or (ii) the holder has not been notified by the Internal Revenue Service that such holder is subject to backup withholding as a result of a failure to report all interest or dividends or (iii) the Internal Revenue Service has notified the holder that such holder is no longer subject to backup withholding. If the tendering holder of Original Notes is a nonresident alien or foreign entity not subject to backup withholding, such holder must give the Exchange Agent a completed Form W-8, Certificate of Foreign Status. These forms may be obtained from the Exchange Agent. If the Original Notes are in more than one name or are not in the name of the actual owner, such holder should consult the W-9 Guidelines for information on which TIN to report. If such holder does not have a TIN, such holder should consult the W-9 Guidelines for instructions on applying for a TIN, check the box in Part 2 of the Substitute Form W-9 and write "applied for" in lieu of its TIN. Note: Checking this box and writing "applied for" on the form means that such holder has already applied for a TIN or that such holder intends to apply for one in the near future. If the box in Part 2 of the Substitute Form W-9 is checked, the Exchange Agent will retain 31% of reportable payments made to a holder during the sixty (60) day period following the date of the Substitute Form W-9. If the holder furnishes the Exchange Agent with his or her TIN within sixty (60) days of the Substitute Form W-9, the Exchange Agent will remit such amounts retained during such sixty (60) day period to such holder and no further amounts will be retained or withheld from payments made to the holder thereafter. If, however, such holder does not provide its TIN to the Exchange Agent within such sixty (60) day period, the Exchange Agent will remit such previously withheld amounts to the Internal Revenue Service as backup withholding and will withhold 31% of all reportable payments to the holder thereafter until such holder furnishes its TIN to the Exchange Agent.

6. Transfer Taxes.

The Company will pay all transfer taxes, if any, applicable to the transfer of Original Notes to it or its order pursuant to the Exchange Offer. If, however, Exchange Notes and/or substitute Original Notes not exchanged are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Original Notes tendered hereby, or if tendered Original Notes are registered in the name of any person other than the person signing this Letter, or if a transfer tax is imposed for any reason other than the transfer of Original Notes to the Company or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering holder.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Original Notes specified in this letter.

7. Waiver of Conditions.

The Company reserves the absolute right to waive satisfaction of any or all conditions enumerated in the Prospectus.

8. No Condition Tenders.

No alternative, conditional, irregular or contingent tenders will be accepted. All tendering holders of Original Notes, by execution of this Letter, shall waive any right to receive notice of the acceptance of their Original


Notes for exchange.

Neither the Company, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Original Notes nor shall any of them incur any liability for failure to give any such notice.

9. Mutilated, Lost, Stolen or Destroyed Original Notes.

Any holder whose Original Notes have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions.

10. Withdrawal Rights.

Tenders of Original Notes may be withdrawn at any time prior to 5:00 P.M., New York City time, on the Expiration Date.

For a withdrawal of a tender of Original Notes to be effective, a written notice of withdrawal must be received by the Exchange Agent at the address set forth above prior to 5:00 P.M., New York City time, on the Expiration Date. Any such notice of withdrawal must (i) specify the name of the person having tendered the Original Notes to be withdrawn (the "Depositor"), (ii) identify the Original Notes to be withdrawn (including certificate number or numbers and the principal amount of such Original Notes), (iii) contain a statement that such holder is withdrawing his election to have such Original Notes exchanged, (iv) be signed by the holder in the same manner as the original signature on the Letter by which such 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 such Original Notes in the name of the person withdrawing the tender and (v) specify the name in which such Original Notes are registered, if different from that of the Depositor. If Original Notes have been tendered pursuant to the procedure for book-entry transfer set forth in "The Exchange Offer--Book-Entry Transfer" section of the Prospectus, 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 and otherwise comply with the procedures of such facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by the Company, whose determination shall be final and binding on all parties. Any Original Notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the Exchange Offer and no Exchange Notes will be issued with respect thereto unless the Original Notes so withdrawn are validly retendered. Any Original Notes that have been tendered for exchange but which are not exchanged for any reason will be returned to the Holder thereof without cost to such Holder (or, in the case of Original Notes tendered by book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry transfer procedures set forth in "The Exchange Offer--Book-Entry Transfer" section of the Prospectus, such Original Notes will be credited to an account maintained with the Book-Entry Transfer Facility for the Original Notes) as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Original Notes may be retendered by following the procedures described above at any time on or prior to 5:00 P.M., New York City time, on the Expiration Date.

11. Requests for Assistance or Additional Copies.
