7

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

(C)                               if such Definitive Notes 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 Note) and (ii) if the Company or Security Registrar 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 2.5(e)(i).

(c)                                  Transfer and Exchange of Global Notes.

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

(iii)                               Notwithstanding any other provisions of this Supplemental Indenture (other than the provisions set forth in Section 2.6), a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(iv)                              In the event that a Global Note is exchanged for Definitive Notes pursuant to Section 2.6 prior to the consummation of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.5 (including the certification requirements set forth on the reverse of the Initial Notes intended to ensure that such transfers comply with Rule 144, 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.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities designated therein referred to in the within-mentioned Indenture.

A6-3

[FORM OF REVERSE OF SECURITY]

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of November 8, 2012, as it may be supplemented or amended from time to time (herein called the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture) and Supplemental Indenture No. 1, dated as of November 8, 2012 (herein called the “Supplemental Indenture”), among the Company and the Trustee, to which Indenture, Supplemental Indenture and all supplemental indentures 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 series designated on the face hereof, in an initial aggregate principal amount of $500,000,000.

The Securities of this series may not be redeemed prior to maturity.

The Securities of this series do not provide for a sinking fund.

Interest payable on any Floating Rate Note Interest Payment Date (as defined herein) or the Floating Rate Note Maturity Date (as defined herein) shall be the amount accrued from, and including, the immediately preceding Floating Rate Note Interest Payment Date in respect of which interest has been paid or duly provided for (or, with respect to the first Floating Rate Note Interest Payment Date only, beginning on November 8, 2012) to, but excluding, such Floating Rate Note Interest Payment Date or Floating Rate Note Maturity Date, as the case may be (each, a “Floating Rate Note Interest Period”).

Interest on the Securities of this series shall be payable quarterly in arrears on February 6, May 6, August 6 and November 6 of each year, beginning on February 6, 2013 (each such date, a “Floating Rate Note Interest Payment Date”), to the persons in whose names the Securities of this series are registered at the close of business on the date that is fifteen calendar days prior to the relevant Floating Rate Note Interest Payment Date (whether or not a Business Day). If any Floating Rate Note Interest Payment Date, other than the Floating Rate Note Maturity Date, is not a New York Business Day, the interest payment due on such day shall be made on the next succeeding day that is a New York Business Day; provided, that if the next succeeding day that is a New York Business Day is in the next succeeding calendar month, the interest payment due on such Floating Rate Note Interest Payment Date shall be made on the immediately preceding New York Business Day. If the Floating Rate Note Maturity Date is not a New York Business Day, the principal amount of the Securities of this series plus accrued and unpaid interest thereon shall be paid on the next succeeding day that is a New York Business Day and no interest shall accrue in respect of the delay in such payment, for the Floating Rate Note Maturity Date or any day thereafter.

The Securities of this series will bear interest for each Floating Rate Note Interest Period at a rate per annum calculated by the Calculation Agent, equal to the then-applicable Three-Month LIBOR, determined on the applicable Interest Determination Date plus 0.760% (76 basis points). Interest on the Securities of this series will be calculated on the basis of the actual

A6-4

number of calendar days in the calculation period divided by 360. The “Calculation Agent” shall be the agent appointed by the Company to calculate the interest rate on the Securities of this series and will initially be the Trustee. The Calculation Agent shall calculate the interest rate and amount of interest to be paid for each Floating Rate Note Interest Period in accordance with the foregoing and notify the Paying Agent thereof. All calculations made by the Calculation Agent shall in the absence of manifest error be conclusive for all purposes and binding on the Company, the Trustee and the Holders of the Securities of this series. For so long as Three-Month LIBOR is required to be determined with respect to the Securities of this series, the Company shall have a Calculation Agent. In the event that the Calculation Agent is unable or unwilling to act, the Calculation Agent fails to duly establish Three-Month LIBOR for any Interest Period or the Company proposes to remove the Calculation Agent, the Company shall appoint itself or another person that is a bank, trust company, investment banking firm or other financial institution to act as the Calculation Agent.

“Interest Determination Date” means the second London Business Day immediately preceding the applicable Interest Reset Date. The Interest Determination Date for the initial Floating Rate Note Interest Period will be November 6, 2012 (the second London Business Day immediately preceding settlement for the Securities of this series).

“Interest Reset Date” means the first day of each Floating Rate Note Interest Period other than the initial Floating Rate Note Interest Period.

“London Business Day” means a day on which commercial banks are open for business (transacting dealings in U.S. dollars) in London.

“New York Business Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York and on which commercial banks are open for business in New York, New York.

The “Three-Month LIBOR,” for any Interest Determination Date, will be the offered rate for deposits in the London interbank market in U.S. dollars having an index maturity of three months, as such rate appears on the Reuters Page LIBOR 01 (or on such other page as may replace Reuters Page LIBOR 01 on that service, or, if on such Interest Determination Date, the Three-Month LIBOR does not appear or is not available on the designated Reuters Page, the Bloomberg L.P. page “BBAM” or such other page as may replace the Bloomberg L.P. page “BBAM” on that service) as of approximately 11:00 a.m., London time, on such Interest Determination Date.  If Three-Month LIBOR does not appear on either of the pages described above, the Three-Month LIBOR, in respect of such Interest Determination Date, will be determined as follows: the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Calculation Agent (after consultation with the Company), to provide the Calculation Agent with its offered quotation for deposits in U.S. dollars for the period of three months commencing on the applicable Interest Reset Date, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount of not less than $1,000,000 for a single transaction in U.S. dollars in such market at such time. If at least two quotations are provided, then the Three-Month LIBOR on such Interest Determination Date will be the arithmetic mean of such quotations. If fewer than two such quotations are

A6-5

provided, then the Three-Month LIBOR on such Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York City time, on such Interest Determination Date by three major reference banks in New York City selected by the Calculation Agent (after consultation with the Company) for loans in U.S. dollars to leading European banks, having an index maturity of three months and in a principal amount of not less than $1,000,000 for a single transaction in U.S. dollars in such market at such time; provided, however, that if the banks selected by the Calculation Agent are not providing quotations in the manner described by this sentence, the Three-Month LIBOR determined as of such Interest Determination Date will be the Three-Month LIBOR in effect prior to such Interest Determination Date.

Notwithstanding the foregoing, the interest rate shall in no event be higher than the maximum rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application.

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.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein.  Sections 13.2 and 13.3 of the Indenture apply to the Securities of this series.

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 not less than 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 at the time Outstanding of any series, 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 or Supplemental Indenture and no provision of this Security or of the Indenture or Supplemental Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where

A6-6

the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar 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.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, 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.

The Securities of this series initially will be fully and unconditionally guaranteed on a unsecured, unsubordinated basis by Abbott Laboratories (the “Guarantor”), pursuant to its guarantee (the “Parent Guarantee”) made under the terms and provisions of a Guarantee Agreement dated November 8, 2012, between the Guarantor and the Trustee (the “Guarantee Agreement”).  The Parent Guarantee shall continue in full force and effect for the benefit of the Holders of the Securities and the Trustee until such Parent Guarantee is terminated and released in accordance with the terms of the Guarantee Agreement.

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.

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 be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture and Supplemental Indenture shall have the meanings assigned to them in the Indenture and Supplemental Indenture.

THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

This Security is a Book-Entry Security within the meaning of the Indenture hereinafter referred to and is registered in the name of a Depository or a nominee of a Depository.  This Security is exchangeable for Securities registered in the name of a person other than the Depository or its nominee only in the limited circumstances described in the Indenture and may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository.
