REVERSE OF SECURITY

THE DOW CHEMICAL COMPANY

DOW INTERNOTES^SM

1. General. This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued in one or more series under an Indenture, dated as of May 1, 2008 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the Securities of the series designated on the face hereof. The Securities of this series may bear different dates, mature at different times and bear interest at different rates. The Securities of this series may be issued from time to time in an unlimited aggregate principal amount.

2. Redemption at the Option of the Company. Unless a Redemption Right is specified on the face hereof, this Security shall not be redeemable at the option of the Company before the Maturity Date specified on the face hereof. If a Redemption Right is so specified, this Security may be redeemed at the option of the Company on any Interest Payment Date on and after the date, if any, specified on the face hereof (each, a “Redemption Date”). This Security may be redeemed on any Redemption Date in whole or in part in increments of $1,000 (an “Authorized Denomination”) at the option of the Company at a redemption price equal to 100% of the principal amount to be redeemed, together with accrued interest to the Redemption Date, on written notice given not more than 60 days nor less than 30 days prior to the proposed Redemption Date. In the event of redemption of this Security in part only, a new Security for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the surrender hereof.

3. Repayment at the Option of the Holder. Unless a Repayment Right is specified on the face hereof, this Security shall not be repayable at the option of the Holder on any date prior to the Maturity Date specified on the face hereof, other than in connection with any applicable Survivor’s Option (defined below). If a Repayment Right is so specified, this Security is subject to repayment at the option of the Holder on any Interest Payment Date on and after the date, if any, indicated on the face hereof (each, a “Repayment Date”). On any Repayment Date this Security shall be repayable in whole or in part in increments of $1,000 at the option of the Holder hereof at a repayment price equal to 100% of the principal amount to be repaid, together with accrued interest thereon to the Repayment Date. In order for a Security to be repaid in whole or in part at the option of the Holder, the Trustee must receive, at the Corporate Trust Office, or such other office of which the Company shall from time to time notify the holders of the Securities, at least 30 but not more than 60 days prior to the Repayment Date on which this Security is to be repaid, this Security with the form entitled “Option to Elect Repayment” below duly completed. Once this Security is delivered for repayment, the Holder may not revoke its exercise of the repayment option.

4. Repayment Upon Death. If the Survivor’s Option is affirmatively specified on the face hereof, the Holder of the Security shall have the right to require the Company to repay a Security prior to its maturity date upon the death of the beneficial owner of the Security as described below. The Company calls this right the “Survivor’s Option.”

10

Upon exercise of the Survivor’s Option, the Company will, at its option, either repay or repurchase any Security (or portion thereof) properly tendered for repayment by or on behalf of the person (the “Representative”) that has authority to act on behalf of the deceased beneficial owner of the Security at a price equal to the sum of:

subject to the following limitations.

The Survivor’s Option may not be exercised unless the Security was owned by the beneficial owner or the estate of that beneficial owner at least six months prior to such exercise. In addition, the Company may limit the aggregate principal amount of Securities as to which the Survivor’s Option may be exercised as follows:

The Company will not make principal repayments pursuant to the exercise of the Survivor’s Option except in principal amounts of $1,000 and multiples of $1,000. If the limitations described above would result in the partial repayment of any Security, the principal amount of the Security remaining outstanding after repayment must be at least $1,000.

An otherwise valid election to exercise the Survivor’s Option may not be withdrawn. Each Security (or portion thereof) tendered pursuant to a valid exercise of the Survivor’s Option will be accepted in the order all such Securities are received by the Trustee, unless the acceptance of that Security would contravene the annual put limitation or the individual put limitation. If, as of the end of any calendar year, the aggregate principal amount of Securities (or portions thereof) that have been tendered pursuant to the valid exercise of the Survivor’s Option during that year has exceeded either the annual put limitation or the individual put limitation for that year, any exercise(s) of the Survivor’s Option with respect to Securities (or portions thereof) not accepted during such calendar year because such acceptance would have contravened either such limitation shall be deemed to be tendered in the following calendar year in the order all such Securities (or portions thereof) were originally tendered.

Any Security (or portion thereof) accepted for repayment or repurchase pursuant to exercise of the Survivor’s Option will be repaid or repurchased on the first Interest Payment Date to occur at least 20 calendar days after the date of acceptance. If that date is not a Business Day,

11

payment will be made on the next succeeding Business Day. In the event that a Security (or any portion thereof) tendered for repayment or repurchase pursuant to valid exercise of the Survivor’s Option is not accepted, the Trustee will deliver a notice by first-class mail to the registered Holder, at that Holder’s last known address as indicated in the Security register, that states the reason that the Security (or portion thereof) has not been accepted for repayment.

Subject to the foregoing, in order to validly exercise a Survivor’s Option, the Trustee must receive from the representative of the deceased beneficial owner:

Subject to the annual put limitation and the individual put limitation, all questions as to the eligibility or validity of any exercise of the Survivor’s Option will be determined by the Trustee in its sole discretion. The Trustee’s determination will be final and binding on all parties.

The death of a person holding a beneficial interest in a Security as a joint tenant or tenant by the entirety with another person, or as a tenant in common with the deceased Holder’s spouse, will be deemed the death of the beneficial owner of the Security, and the entire principal amount of the Security so held will be subject to the Survivor’s Option. The death of a person holding a beneficial interest in a Security as a tenant in common with a person other than such deceased Holder’s spouse will be deemed the death of the beneficial owner of a Security only with respect to the deceased Holder’s interest in the Security. The death of a person who, during his or her lifetime, was entitled to substantially all of the beneficial interests of ownership of a Security will

12

be deemed the death of the beneficial owner for purposes of the Survivor’s Option, regardless of the registered Holder of the Security, if such beneficial interest can be established to the satisfaction of the Trustee. Such beneficial interest will be deemed to exist in typical cases of nominee ownership, ownership under the Uniform Transfers to Minors Act or Uniform Gifts to Minors Act, community property or other joint ownership arrangements between a husband and wife and custodial and trust arrangements where one person has substantially all of the beneficial ownership interest in the Security during his or her lifetime.

For Securities represented by a Global Security, the Depositary or its nominee shall be the holder of such Security and therefore shall be the only entity that can exercise the Survivor’s Option for such Security. To obtain repayment or repurchase pursuant to exercise of the Survivor’s Option with respect to such Security, the Representative must provide to the broker or other entity through which the beneficial interest in such Security is held by the deceased beneficial owner (i) the documents described in the third preceding paragraph and (ii) written instructions to such broker or other entity to notify the Depositary of such Representative’s desire to obtain repayment or repurchase pursuant to exercise of the Survivor’s Option. Such broker or other entity shall provide to the Trustee (i) the documents received from the Representative referred to in clause (i) of the preceding sentence and (ii) a certificate satisfactory to the Trustee from such broker or other entity stating that it represents the deceased beneficial owner. Such broker or other entity shall be responsible for disbursing any payments it receives pursuant to exercise of the Survivor’s Option to the appropriate Representative.

5. Events of Default. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

6. Modifications and Waivers; Obligation of the Company Absolute. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of at least a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed.

7. Authorized Denominations. The Securities are issuable in registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture, and subject to certain limitations therein set forth and to the limitations described below, if applicable, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

13

8. Registration of Transfer. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security register upon surrender of this Security for registration of transfer at the office or agency of the Company maintained for that purpose in the City of Chicago, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the securities registrar (which shall initially be the Trustee, The Bank of New York Mellon Trust Company, N.A., Two North LaSalle Street, Chicago, Illinois 60602 (Attention: Corporate Trust Department) or at such other address as it may designate as its principal corporate trust office in the City of Chicago), duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

This Security is exchangeable only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for this Security or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, (y) the Company in its sole discretion determines that this Security shall be exchangeable for certificated Securities in registered form or (z) an Event of Default, or an event which with the passage of time or the giving of notice would become an Event of Default, with respect to the Securities represented hereby has occurred and is continuing, provided that the definitive Securities so issued in exchange for this permanent Security shall be in denominations of $1,000 and any integral multiple of $1,000 in excess thereof and be of like aggregate principal amount and tenor as the portion of this permanent Security to be exchanged, and provided further that, unless the Company agrees otherwise, Securities of this series in certificated registered form will be issued in exchange for this permanent Security, or any portion hereof, only if such Securities in certificated registered form were requested by written notice to the Trustee or the Securities Registrar by or on behalf of a person who is beneficial owner of an interest hereof given through the Holder hereof. Except as provided above, owners of beneficial interests in this permanent Security will not be entitled to receive physical delivery of Securities in certificated registered form and will not be considered the Holders thereof for any purpose under the Indenture.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

9. Owners. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

10. No Recourse Against Certain Persons. No recourse for the payment of the principal or interest on this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any Supplemental Indenture thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator,
