Section 2.3.          
Interest on the Floating Rate Notes. Interest on the Floating Rate Notes will accrue from
(and including) the most recent date on which interest has been paid or duly provided for by Allergan Funding SCS on the Allergan
2020 Floating Rate Notes (as defined in the Offering Memorandum and Consent Solicitation Statement) that were accepted in the Exchange
Offers. Interest on the Floating Rate Notes will be payable on the applicable interest payment dates set forth in Exhibit A1 attached
hereto. The first interest payment date on the Floating Rate Notes is set forth in Exhibit A1 attached hereto. Interest will be
payable to the Persons in whose names the Floating Rate Notes are registered at the close of business on the 15th calendar day
immediately preceding the interest payment date (whether or not a Business Day) (such day, the “Floating Rate Notes Record
Date”). However, interest paid on the maturity date will be payable to the Person to whom the principal will be payable.
The amount of interest for each day that the Floating Rate Notes are outstanding (the “Daily Interest Amount”)
will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount
of the Floating Rate Notes outstanding on such day. The amount of interest to be paid on the Floating Rate Notes for each interest
period will be calculated by adding such Daily Interest Amounts for each day in such interest period.


 


Section 2.4.          
Interest on the Fixed Rate Notes. Interest on each series of Fixed Rate Notes will accrue
from (and including) the most recent date on which interest has been paid or duly provided for by Allergan Funding SCS on the corresponding
series of Allergan Euro Notes (as defined in the Offering Memorandum and Consent Solicitation Statement) that were accepted in
the Exchange Offers. Interest on each series of Fixed Rate Notes will be payable on the applicable interest payment dates set forth
in the corresponding Exhibits A2-A6 attached hereto. The first interest payment date on each series of the Fixed Rate Notes is
set forth in the corresponding Exhibits A2-A6 attached hereto. Interest will be payable to the Persons in whose names the Fixed
Rate Notes are registered at the close of business on the date that is (i) in the case of Fixed Rate Notes represented by a Global
Note, the clearing system business day (which, for these purposes, is a day on which Euroclear and Clearstream settle payments
in euro) immediately prior to the relevant interest payment date and (ii) in all other cases, 15 calendar days prior to the relevant
interest payment date (whether or not a Business Day) (such day, the “Fixed Rate Notes Record Date” and, together
with the Floating Rate Notes Record Date, the “Record Date”). Interest on the Fixed Rate Notes shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Fixed Rate Notes, but excluding the next following interest payment date. This
payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

Section 2.5.          
Issuance In Euro. All payments of principal of, and premium, if any, and interest on, the
Notes, including payments made upon any redemption of the Notes, shall be payable in euro. If the Company is unable to obtain euro
in amounts sufficient to make a required payment under the Notes due to the imposition of exchange controls or other circumstances
beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro is no longer being
used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement
of transactions by public institutions or within the international banking community, then all payments in respect of the Notes
shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such circumstances, the amount payable
on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal Reserve Board as of the close
of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not
mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate available on or prior to the
second business day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment in respect
of the Notes so made in U.S. Dollar shall not constitute an Event of Default under the Notes or the Indenture. Neither the Trustee
nor the Paying Agent shall have any responsibility for any calculation or conversion in connection with the foregoing. 


 


Section 2.6.          
Form and Dating.


 


(a)           
General.  The Notes shall initially be issued in the form of one or more Global
Notes in fully registered, book-entry form, duly executed by the Company and authenticated by the Trustee, which shall be deposited
with the Common Depositary and shall be registered in the name of USB Nominees (UK) Limited, as nominee of Elavon Financial Services
DAC, as common depositary for Euroclear and Clearstream. The Notes shall be substantially in the forms set forth in the corresponding
Exhibits A1-A6 attached hereto (other than, (i) with respect to any additional Notes of any series of the Notes, changes related
to issue date, issue price and first interest payment date of such additional Notes, and (ii) with respect to any Exchange Notes

 €100,000 and integral multiples of €1,000 in excess thereof. The Notes of each series and any additional Notes of such
series subsequently issued under the Indenture, together with any Exchange Notes issued with respect to the Notes of such series
in accordance with the Registration Rights Agreement, will be treated as a single series or class for all purposes under the Indenture,
including, without limitation, waivers, amendments and redemptions; provided that, if any such additional Notes are not fungible
with the existing Notes for Federal income tax purposes, such additional Notes will have a separate CUSIP number.


 


i.           
The Notes shall initially be issued only (A) to persons reasonably believed to be QIBs in reliance on Rule 144A
or (B) outside the United States, to persons other than “U.S. persons” as defined in Rule 902 under the Securities
Act, in compliance with Regulation S. Notes may thereafter be transferred to, among others, purchasers reasonably believed
to be QIBs, and purchasers in reliance on Regulation S, subject to the restrictions on transfer set forth herein. Notes initially
issued pursuant to Rule 144A shall be issued in the form of one or more permanent global securities in fully registered form
(collectively, the “Rule 144A Global Note”) and Notes initially issued pursuant to Regulation S shall
be issued in the form of one or more permanent global securities in fully registered form (collectively, the “Regulation S
Global Note”), in each case without interest coupons and with the Global Notes Legend and the applicable Restricted Notes
Legend set forth in Section 2.7(e)(i) hereof, which shall be deposited on behalf of the purchasers of the Notes represented thereby
with the Common Depositary and shall be registered in the name of USB Nominees (UK) Limited, as nominee of the Common Depositary
for such Global Note or Global Notes, duly executed by the Company and authenticated by the Trustee as provided in this Supplemental

ii.           
Beneficial interests in Regulation S Global Notes may be exchanged for interests in Rule 144A Global Notes of
the same series if (1) such exchange occurs in connection with a transfer of Notes in compliance with Rule 144A and (2) the
transferor of the beneficial interest in the Regulation S Global Note first delivers to the Trustee a written certificate
(in the form of the Form of Exchange Certificate attached to the applicable Exhibit hereto) to the effect that the beneficial interest
in the Regulation S Global Note is being transferred to a Person (A) who the transferor reasonably believes to be a QIB,
(B) purchasing for its own account or the account of a QIB in a transaction meeting the requirements of Rule 144A, and
(C) in accordance with all applicable securities laws of the States of the United States and other jurisdictions.


 


iii.           
Beneficial interests in Rule 144A Global Notes may be transferred to a Person who takes delivery in the form of an
interest in a Regulation S Global Note only if the transferor first delivers to the Trustee a written certificate (in the
form of Exhibit B hereto) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S
(if applicable).


 


iv.           
The Rule 144A Global Notes and the Regulation S Global Notes are collectively referred to herein as “Global
Notes.”


 


The
terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Supplemental Indenture,
and the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions
of this Supplemental Indenture, the provisions of this Supplemental Indenture shall govern and be controlling.


 


(b)              
Book-Entry Provisions.  This Section 2.6(b) shall apply only to a Global Note deposited with the Common
Depositary. The Company shall execute and the Trustee shall, in accordance with this Section 2.6(b) and pursuant to an
order of the Company, authenticate and deliver initially one or more Global Notes that (A) shall be registered in the name
of USB Nominees (UK) Limited, as nominee of the Common Depositary for such Global Note or Global Notes and (B) shall be delivered
by the Trustee to such Common Depositary.


 






    	 	8	 



     


    

 


(c)              
Payment. The Company will make payments on the Notes in euro at the office of the Trustee (in the limited circumstances
specified in the Indenture), the Paying Agent or any paying agent the Company designates (which paying agent may include the Company).
At its option, the Company may make payments of interest by (i) check mailed to the address of the Person entitled thereto
as such address shall appear in the Security Register or (ii) wire transfer as directed by the Holder of any Note, in immediately
available funds to an account maintained by the Common Depositary or its nominee with respect to a Global Note, and to the Holder
of any Note or its nominee with respect to a Definitive Note; provided further that in the case of a Definitive Note (x)
the Holder thereof shall have provided written wiring instructions to the Paying Agent on or before the related Record Date and
(y) if appropriate instructions for any such wire transfer are not received by the related Record Date, then such payment
shall be made by check mailed to the address of such Holder specified in the Security Register. The Company will make interest
payments to the Holder in whose name the Note is registered at the close of business on the Record Date for the interest payment.


 


Payment of principal in respect of the Notes
and payment of accrued interest payable on redemption of the Notes (other than on an interest payment date) will be made to the
Persons shown in the Security Register at the close of business on the Record Date, subject to surrender (or in the case of partial
payment only, endorsement) of the relevant note, at the specified office of the Paying Agent. Payments of interest due on any interest
payment date will be made to the Persons shown in the Security Register at close of business on the Record Date. Payments of all
other amounts will be made as provided in the Indenture.


 


If the principal of or any premium or interest
on the Notes is payable on a day that is not a Payment Business Day, the payment will be made on the following Payment Business
Day without the accrual of any interest on that payment.


 


For these purposes “Payment Business
Day” means any day that is:


 


		a)	a day on which commercial banks and foreign exchange markets settle payments and are open for general business (including dealing
in foreign exchange and foreign currency deposits) in, in the case of Definitive Notes only, the relevant place of presentation;



 


		b)	a day on which the TARGET2 System is open; and

payments in euro.



 


For these purposes “TARGET2 System”
means the Trans-European Automatic Realtime Gross Settlement Express Transfer (TARGET2) System.


 


All payments of any amounts paid to or to
the order of USB Nominees (UK) Limited, as nominee for the Common Depositary for Euroclear and Clearstream shall be valid and,
to the extent of the sums so paid, effectual to satisfy and discharge the liability of the Company for the moneys payable on the
Notes.

The Company has designated the Paying Agent
as its paying agent for payments on Notes. The Company may at any time designate additional paying agents or rescind the designation
of any paying agent or approve a change in the office through which any paying agent acts.


 


The Trustee or Paying Agent, as applicable,
will repay to the Company on the Company’s written request any funds they hold for payments on the Notes that remain unclaimed
for two years after the date upon which that payment has become due. After repayment to the Company, Holders entitled to those
funds must look only to it for payment.


 


(d)              
Definitive Notes.  Except as provided in this Section 2.6, owners of a beneficial interest in the Global
Notes will not have Notes registered in their names, will not receive physical delivery of Definitive Notes and will not be considered

such instructions to contain information regarding the Common Depositary account to be credited with such increase, then the Trustee
shall cancel such Definitive Note and cause the aggregate principal amount of Notes represented by the Global Note to be increased
by the aggregate principal amount of the Definitive Note 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 Note equal to the principal amount of the Definitive
Note so canceled. If no Global Notes are then outstanding and the Global Note has not been previously exchanged for certificated
securities pursuant to this Section 2.7, the Company shall issue and the Trustee shall authenticate, upon receipt of a Company
Order, a new Global Note in the appropriate principal amount.


 


(c)              
Exchange of Global Notes for Definitive Notes. A Global Note shall be exchanged by the Company for Definitive Notes
only if:


 


(i)                
an Event of Default has occurred and is continuing; or


 


(ii)             
either Euroclear or Clearstream is closed for business for a continuous period of 14 days or more (other than by reason
of holiday, statutory or otherwise) or announces an intention permanently to cease business or does in fact do so and no alternative
clearing system satisfactory to the Trustee is available; or


 


(iii)           
the Company would suffer a disadvantage as a result of a change in laws or regulations (taxation or otherwise) or as a result
of a change in the practice of Euroclear and/or Clearstream which would not be suffered were the Notes in definitive form and a
certificate to such effect signed by an authorized signatory of the Company is given to the Trustee.


 


In the case of (i) or (ii) above,
the Holder of a Global Note (acting on behalf of one or more of the accountholders) or the Trustee may give notice to the Company
and, in the case of (iii) above, the Company may give notice to the Trustee and the Holders of Notes, of its intention to
exchange a Global Note for Definitive Notes on or after the Exchange Date (as defined below).


 






    	 	11	 



     


    

 


On or after the Exchange Date the Holder
of the Global Note may, or in the case of (iii) above, shall surrender it to or to the order of the Paying Agent. In exchange
for the Global Note, the Company shall deliver, or procure the delivery of, an equal aggregate principal amount of Definitive Notes,
security printed in accordance with any applicable legal and stock exchange requirements. On exchange of the Global Note, the Company
will procure that it is cancelled and, if the Holder so requests, returned to the Holder together with any relevant Definitive
Notes.


 


For these purposes, “Exchange Date”
means a day specified in the notice requiring exchange falling not less than 60 days after that on which the notice requiring
exchange is given and being a day on which banks are open for general business in London, the place in which the specified office
of the Paying Agent is located and, except in the case of exchange pursuant to (ii) above, in the place in which Euroclear
and Clearstream are located.


 


In all cases, Definitive Notes delivered
in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved
denominations, requested by or on behalf of the Holder of the relevant Global Notes.


 


In the event that Global Notes are exchanged
for Definitive Notes 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 (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.


 


None of the Company, the Trustee, the Paying
Agent or the Security Registrar will be liable for any delay by the Holder of the relevant Global Notes in identifying the Holders
of beneficial interests in the Global Notes, and each such Person may conclusively rely on, and will be protected in relying on,
instructions from Euroclear or Clearstream for all purposes (including with respect to the registration and delivery, and the respective
principal amounts, of the Definitive Notes to be issued).

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


 


(i)       Prior
to the expiration of the Restricted Period, interests in a Regulation S Global Note may only be held through Euroclear or
Clearstream. During the Restricted Period, beneficial ownership interests in a Regulation S Global Note 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 available exemption from registration under the Securities Act or (E) 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;
provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in a
Regulation S Global Note may not be made to a U.S. person or for the account or benefit of a U.S. person. Prior to the expiration
of the Restricted Period, transfers by an owner of a beneficial interest in a Regulation S Global Note to a transferee who
takes delivery of such interest through a Rule 144A Global Note shall be made only in accordance with the Applicable Procedures,
pursuant to Rule 144 or Rule 144A and upon receipt by the Trustee of a written certification from the transferor of the
beneficial interest in the form provided on the reverse of the Initial Note to the effect that such transfer is being made to 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. 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 Note for an interest in a Rule 144A Global Note,
the transferee must, at the request of the Company, deliver an opinion of counsel reasonably acceptable to the Company stating
that the proposed transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements
of the Securities Act.


 


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


 


(e)              
Legends.


 


(i)       Except
as permitted by the following paragraphs (ii), (iii), (iv) or (v), each Note certificate evidencing the Global Notes and the

THE COMMON DEPOSITARY TO A NOMINEE THEREOF OR BY A NOMINEE THEREOF TO THE COMMON DEPOSITARY OR ANOTHER NOMINEE OF THE COMMON DEPOSITARY
OR BY THE COMMON DEPOSITARY OR A NOMINEE OF THE COMMON DEPOSITARY TO A SUCCESSOR COMMON DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR

    	 	15	 



     


    

 


(iii)       After
a transfer of any Initial Notes during the period of the effectiveness of a shelf registration statement with respect to such Initial

an interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global
Note shall be reduced and an adjustment shall be made on the books and records of the Security Registrar with respect to such Global
Note, by the Security Registrar, to reflect such reduction.

as would have been the case if such covenant defeasance had not occurred.

Solely with respect to the Notes, the term “U.S. Government Obligations,” defined in Section 13.4 of
the Indenture, shall be deleted and replaced with the following: “euro denominated securities that are direct obligations
(or certificates representing an ownership interest in such obligations) of a member state of the European Union as of the Issue
Date (including any agency or instrumentality thereof) for the payment of which the full faith and credit of such government is
pledged; provided that such member state has a long-term government debt rating of “A1” or higher by Moody’s

ABBVIE INC., a corporation duly organized

Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule

provided for.


 


Payments of principal
of, and premium, if any, and interest on, this Security, including payments made upon any redemption of this Security, shall be
made by wire transfer of immediately available funds in euro. If the euro is unavailable to the Company due to the imposition of

all payments in respect of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used.
In such circumstances, the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the
U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date, or in the
event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro
exchange rate available on or prior to the second business day prior to the relevant payment date as determined by the Company
in its sole discretion. Any payment in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default

[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 “Base 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. 9,
dated as of May 14, 2020 (herein called the “Supplemental Indenture”) among the Company, the Trustee, Elavon
Financial Services DAC, U.K. Branch, as paying agent (the “Paying Agent”), and U.S. Bank National Association,
as transfer agent and registrar (the “Transfer Agent” and “Security Registrar”) (the “Supplemental
Indenture No. 9,” and together with the Base Indenture, the “Indenture”), 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 of this series
and of the terms upon which the Securities of this series 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 €[●].


 


Interest


 


Interest shall be paid at a rate per annum
equal to EURIBOR (as defined below), as determined on the applicable Interest Determination Date (as defined below) by the Calculation
Agent (as defined below), plus 0.350%; provided, however, that the minimum interest rate on the Securities shall
not be less than 0.000%. The interest rate on the Securities shall be reset on the first day of each Interest Period (as defined
below) other than the Initial Interest Period (as defined below).


 


The Company shall pay interest on the Securities
from the most recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”)
on the Floating Rate Notes due 2020 issued by Allergan that were accepted in the Exchange Offers, quarterly on February 15, May
15, August 15 and November 15 of each year (each, an “Interest Payment Date”), with the first interest payment
to be made on May 15, 2020.


 


An “Interest Period”
for the Securities means the period commencing on an Interest Payment Date and ending on the day preceding the next following Interest
Payment Date (or, in the case of the Initial Interest Period, commencing on the most recent date on which interest has been paid
or duly provided for by Allergan on the Floating Rate Notes due 2020 issued by Allergan that were accepted in the Exchange Offers).
The “Initial Interest Period” shall be February 15, 2020 through May 14, 2020. The “Interest Determination
Date” for an Interest Period shall be the second TARGET System Day (as defined below) preceding the first day of such
Interest Period (or, in the case of the Initial Interest Period, February 13, 2020).


 


All payments of interest on the Securities
due on any Interest Payment Date shall be made to the Persons in whose name the Securities are registered at the close of business
on the 15th calendar day immediately preceding the relevant Interest Payment Date (whether or not a Business Day (as defined below))
(each such date, a “Regular Record Date”). However, interest that the Company pays on the Maturity Date shall
be payable to the Person to whom the principal shall be payable. The amount of interest for each day that the Securities are outstanding
(the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 360
and multiplying the result by the principal amount of the Securities outstanding on such day. The amount of interest to be paid
on the Securities for each Interest Period will be calculated by adding such Daily Interest Amounts for each day in such Interest
Period.


 






    	 	A-1-7	 



     


    

 


If an Interest Payment Date, other than
the Maturity Date, falls on a day that is not a Business Day, the interest payment shall be postponed to the next day that is a
Business Day, except that if that Business Day is in the next succeeding calendar month, the Interest Payment Date shall be the
immediately preceding Business Day. If the Maturity Date of the Securities falls on a day that is not a Business Day, the payment
of interest and principal shall be made on the next succeeding Business Day, and no interest on such payment shall accrue for the
period from and after the Maturity Date. If any such Interest Payment Date, other than the Maturity Date, is postponed or brought
forward as described above, the amount of interest for the relevant Interest Period will be adjusted accordingly.


 


“EURIBOR”
shall be determined by the Calculation Agent in accordance with the following provisions:


 


		(a)	“EURIBOR,” with respect to any Interest Determination Date, shall be the offered
rate for deposits of euros having a maturity of three months that appears on “Reuters Page EURIBOR 01” (or such other
page as may replace “Reuters Page EURIBOR 01” on such service or any successor service for the purpose of displaying
eurozone interbank offered rates for euro-denominated deposits of major banks) at approximately 11:00 a.m., Brussels time, on such
Interest Determination Date. If no rate appears, then EURIBOR, in respect of that Interest Determination Date, shall be determined
in accordance with the provisions described in (b) below.



 


		(b)	If no offered rate appears on the “Reuters Page EURIBOR 01” on an Interest Determination
Date, as specified in (a) above, EURIBOR shall be determined for such Interest Determination Date on the basis of the rates at
approximately 11:00 a.m., Brussels time, on such Interest Determination Date at which deposits in euros are offered to prime banks
in the eurozone inter-bank market by the principal eurozone office of each of four major banks in such market selected and identified
by the Company (the “Reference Banks”), for a term of three months commencing on the first day of the applicable
Interest Period and in a principal amount of not less than €1,000,000 that is representative for a single transaction in euros
in such market at such time. The Company shall ensure the Calculation Agent is provided with the complete contact details of the
relevant personnel at each of the Reference Banks that they will be required to contact in order to obtain the relevant interest
rate. The Calculation Agent shall request the principal eurozone office of each of the Reference Banks to provide a quotation of
its rate. If at least two such quotations are provided, EURIBOR for such Interest Period shall be the arithmetic mean (rounded
upwards) of such quotations. If fewer than two such quotations are provided, EURIBOR for such Interest Period shall be the arithmetic
mean (rounded upwards) of the rates quoted at approximately 11:00 a.m., Brussels time, on such Interest Determination Date by three
major banks in the eurozone, selected and identified by the Company, for loans in euros to leading European banks, for a term of
three months, commencing on the first day of the applicable Interest Period and in a principal amount of not less than €1,000,000
that is representative for a single transaction in euros in such market at such time; provided, however,
that if the banks so selected do not provide quotes as specified above, the interest rate for the applicable Interest Period shall
be the same as the interest rate for the immediately preceding Interest Period, or, if none, the interest rate for the applicable
Interest Period shall be the interest rate with respect to the Initial Interest Period. 



 






    	 	A-1-8	 



     


    

 


Notwithstanding
the paragraph immediately above, if the Company, in its sole discretion, determines that EURIBOR has been permanently discontinued
and the Company has notified the Calculation Agent of such determination (a “EURIBOR Event”), the Calculation
Agent will use, as a substitute for EURIBOR (the “Alternate Rate”) for each future interest determination date,
the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including
any committee or working group thereof) that is consistent with market practice regarding a substitute for EURIBOR. As part of
such substitution, the Calculation Agent may make such adjustments to the Alternate Rate or the spread thereon, as well as the
business day convention, Interest Determination Dates and related provisions and definitions, in each case that are consistent
with market practice for the use of such Alternate Rate. If a EURIBOR Event has occurred, but for any reason an Alternate Rate
has not been determined, the rate of EURIBOR for the next Interest Period shall be set equal to the rate of EURIBOR for the then
current Interest Period. All percentages resulting from any of the above calculations shall be rounded, if necessary, to the nearest
one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.986865%
(or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all euro amounts used in or resulting from such calculation shall
be rounded to the nearest cent (with one-half cent being rounded upwards). Promptly upon determination, the Calculation Agent shall
inform the Trustee, if applicable, and the Company of the interest rate for the next Interest Period.


 


“Business Day” means
any day, other than a Saturday, Sunday, (i) which is not a day on which banking institutions in New York, New York or London are
authorized or required by law or executive order to close and (ii) on which the Trans European Automated Realtime Gross Settlement
Express Transfer System, or the TARGET2 System, or any successor thereto, operates.


 


“TARGET System Day” means
any day in which the TARGET2 System, or any successor thereto, is open for business and a day on which commercial banks are open
for dealings in euro deposits in the London interbank market. With respect to notes in certificated form, the reference to business
day shall also mean a day on which banking institutions generally are open for business in the location of each office of a transfer
agent, but only with respect to a payment or other action to occur at that office.


 


The “Calculation
Agent” shall be the agent appointed by the Company to calculate the interest rate on the Securities and shall initially
be the Paying Agent. The Calculation Agent shall calculate the interest rate in accordance with the foregoing. On or before each
Calculation Date (as defined below), the Calculation Agent shall determine the interest rate and notify the Paying Agent. The Calculation
Agent shall, upon the request of any Holder of the Securities, provide the interest rate then in effect with respect to the Securities.
All calculations of the Calculation Agent, in the absence of manifest error, shall be conclusive for all purposes and binding on
the Company, the Trustee and the Holders of this Securities. The “Calculation Date” pertaining to any Interest
Determination Date on the Securities shall be the earlier of (i) the tenth calendar day after such Interest Determination Date,
or, if any such day is not a Business Day, the next succeeding Business Day, and (ii) the Business Day immediately preceding the
applicable Interest Payment Date or the Maturity Date, as the case may be.

the manner and with the effect provided in the Indenture.


 


Miscellaneous 


 


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.

principal amount, shall be issued to the designated transferee or transferees.


 


The Securities of this series are issuable
in fully registered form only in denominations of €100,000 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.


 


No service charge shall be made for any
registration of transfer or exchange of the Notes, but the Company or the Security Registrar 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 9.6 or 11.7 of the Indenture).


 


Prior to due presentment of this Security
for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee will treat the Person in whose
name this Security is registered as the owner hereof for the purpose of receiving payments and for all other purposes, whether

(UK) Limited, as nominee of Elavon Financial Services DAC, as common depositary (the “Common Depositary”) for
Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule
of Exchanges attached hereto, on June 1, 2021 (the “Maturity Date”), and to pay interest thereon from the most
recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”) on the
0.500% Senior Notes due 2021 issued by Allergan that were accepted in the Exchange Offers, annually on June 1 (the “Interest

principal and any unpaid and accrued interest are paid or duly provided for.


 


Interest on the Securities shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Securities, but excluding the next following Interest Payment Date. This payment
convention is referred to as ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the International Capital Market Association).

Payments of principal of, and premium, if
any, and interest on, this Security, including payments made upon any redemption of this Security, shall be made by wire transfer
of immediately available funds in euro. If the euro is unavailable to the Company due to the imposition of exchange controls or
other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro
is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or
for the settlement of transactions by public institutions or within the international banking community, then all payments in respect
of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such circumstances,
the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal Reserve Board
as of the close of business on the second business day prior to the relevant payment date, or in the event the U.S. Federal Reserve
Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate available on or
prior to the second business day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment
in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default under this Security or the Indenture.
Neither the Trustee nor the Paying Agent (as defined on the reverse hereof) shall have any responsibility for any calculation or
conversion in connection with the foregoing.

[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 “Base 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. 9,
dated as of May 14, 2020 (herein called the “Supplemental Indenture”), among the Company, the Trustee, Elavon
Financial Services DAC, U.K. Branch, as paying agent (the “Paying Agent”), and U.S. Bank National Association,
as transfer agent and registrar (the “Transfer Agent” and “Security Registrar”) (the “Supplemental
Indenture No. 9”), and together with the Base Indenture, the “Indenture”), 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 of this series
and of the terms upon which the Securities of this series 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 €[●].


 


Optional Redemption 


 


At any time prior to the Par Call Date (as
defined below), the Company may redeem some or all of the Securities of this series at its option, in each case at the Company’s
option, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series to be
redeemed; and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest
accrued to the Redemption Date) on the Securities of this series to be redeemed discounted to the Redemption Date on an annual
basis (ACTUAL/ACTUAL (ICMA)) at the applicable Comparable Government Bond Rate plus 20 basis points.


 


The Company will pay accrued and unpaid
interest on the principal amount of the Securities of this series being redeemed to, but excluding, the Redemption Date.


 


In addition, at any time on or after the
Par Call Date, the Company may redeem some or all of the Securities of this series at its option at a redemption price equal to
100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest on the principal
amount of Securities of this series being redeemed to, but excluding, the Redemption Date. If the Company has given notice as provided
in the Indenture and funds for the redemption of any Securities of this series called for redemption have been made available on
the Redemption Date in accordance with the Indenture, such Securities will cease to bear interest on the date fixed for redemption.
Thereafter, the only right of the Holders of such Securities will be to receive payment of the redemption price.


 






    	 	A-2-7	 



     


    





 


The Company will give notice of any optional
redemption to and through Euroclear or Clearstream for communication by them to the Holders of interests in the Securities not
more than 60 nor less than 15 days prior to the Redemption Date. The notice of redemption will specify, among other items, the
Redemption Date, redemption price, the principal amount of the Securities of this series to be redeemed and the place or places
that payment will be made upon surrender of the Securities of this series to be redeemed. Any redemption or notice of redemption
may, at the Company’s discretion, be subject to one or more conditions precedent, and, at the Company’s discretion,
the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied. The Company shall provide
written notice to the Trustee prior to the close of business two business days prior to the Redemption Date if any such redemption

ABBVIE INC., a corporation duly organized

under the Indenture and Supplemental Indenture hereinafter referred to), for value received, hereby promises to pay to USB Nominees
(UK) Limited, as nominee of Elavon Financial Services DAC, as common depositary (the “Common Depositary”) for
Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule
of Exchanges attached hereto, on November 15, 2023 (the “Maturity Date”), and to pay interest thereon from the
most recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”) on
the 1.500% Senior Notes due 2023 issued by Allergan that were accepted in the Exchange Offers, annually on November 15 (the “Interest

the principal and any unpaid and accrued interest are paid or duly provided for.


 


Interest on the Securities shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Securities, but excluding the next following Interest Payment Date. This payment

Payments of principal of, and premium, if
any, and interest on, this Security, including payments made upon any redemption of this Security, shall be made by wire transfer
of immediately available funds in euro. If the euro is unavailable to the Company due to the imposition of exchange controls or
other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro
is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or
for the settlement of transactions by public institutions or within the international banking community, then all payments in respect
of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such circumstances,
the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal Reserve Board
as of the close of business on the second business day prior to the relevant payment date, or in the event the U.S. Federal Reserve
Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate available on or
prior to the second business day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment
in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default under this Security or the Indenture.
Neither the Trustee nor the Paying Agent (as defined on the reverse hereof) shall have any responsibility for any calculation or
conversion in connection with the foregoing.


 


Reference is hereby made to the further
provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect
as if set forth at this place.

 “Trustee,” which term includes any successor trustee under the Indenture), and Supplemental Indenture No. 9,
dated as of May 14, 2020 (herein called the “Supplemental Indenture”), among the Company, the Trustee, Elavon
Financial Services DAC, U.K. Branch, as paying agent (the “Paying Agent”), and U.S. Bank National Association,
as transfer agent and registrar (the “Transfer Agent” and “Security Registrar”) (the “Supplemental
Indenture No. 9”), and together with the Base Indenture, the “Indenture”), 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 of this series
and of the terms upon which the Securities of this series 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 €[●].


 


Optional Redemption 


 


At any time prior to the Par Call Date (as
defined below), the Company may redeem some or all of the Securities of this series at its option, in each case at the Company’s
option, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series to be
redeemed; and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest
accrued to the Redemption Date) on the Securities of this series to be redeemed discounted to the Redemption Date on an annual
basis (ACTUAL/ACTUAL (ICMA)) at the applicable Comparable Government Bond Rate plus 25 basis points.


 


The Company will pay accrued and unpaid
interest on the principal amount of the Securities of this series being redeemed to, but excluding, the Redemption Date.


 


In addition, at any time on or after the
Par Call Date, the Company may redeem some or all of the Securities of this series at its option at a redemption price equal to
100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest on the principal
amount of Securities of this series being redeemed to, but excluding, the Redemption Date. If the Company has given notice as provided
in the Indenture and funds for the redemption of any Securities of this series called for redemption have been made available on
the Redemption Date in accordance with the Indenture, such Securities will cease to bear interest on the date fixed for redemption.
Thereafter, the only right of the Holders of such Securities will be to receive payment of the redemption price.


 






    	 	A-3-7	 



     


    

 


The Company will give notice of any optional
redemption to and through Euroclear or Clearstream for communication by them to the Holders of interests in the Securities not
more than 60 nor less than 15 days prior to the Redemption Date. The notice of redemption will specify, among other items, the
Redemption Date, redemption price, the principal amount of the Securities of this series to be redeemed and the place or places
that payment will be made upon surrender of the Securities of this series to be redeemed. Any redemption or notice of redemption
may, at the Company’s discretion, be subject to one or more conditions precedent, and, at the Company’s discretion,
the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied. The Company shall provide
written notice to the Trustee prior to the close of business two business days prior to the Redemption Date if any such redemption
has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of Securities in the same
manner in which the notice of redemption was given.


 


The Company will
notify the Trustee at least 30 days prior to the Redemption Date fixed by the Company (or such shorter period as is satisfactory
to the Trustee) of the aggregate principal amount of the Securities of this series to be redeemed and their Redemption Date. If
less than all of the Securities of this series are to be redeemed at any time, the Securities will be selected in accordance with
the rules of Euroclear and Clearstream (to be reflected in the records of Euroclear and Clearstream as either a pool factor or
a reduction in nominal amount, at their discretion).

under the Indenture and Supplemental Indenture hereinafter referred to), for value received, hereby promises to pay to USB Nominees
(UK) Limited, as nominee of Elavon Financial Services DAC, as common depositary (the “Common Depositary”) for
Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule
of Exchanges attached hereto, on June 1, 2024 (the “Maturity Date”), and to pay interest thereon from the most
recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”) on the
1.250% Senior Notes due 2024 issued by Allergan that were accepted in the Exchange Offers, annually on June 1 (the “Interest
Payment Date”), with the first interest payment to be made on June 1, 2020, at the rate of 1.250% per annum, until the
principal and any unpaid and accrued interest are paid or duly provided for.


 


Interest on the Securities shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Securities, but excluding the next following Interest Payment Date. This payment
convention is referred to as ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the International Capital Market Association).

Payments of principal of, and premium, if
any, and interest on, this Security, including payments made upon any redemption of this Security, shall be made by wire transfer

is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or
for the settlement of transactions by public institutions or within the international banking community, then all payments in respect
of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such circumstances,
the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal Reserve Board
as of the close of business on the second business day prior to the relevant payment date, or in the event the U.S. Federal Reserve
Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate available on or
prior to the second business day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment
in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default under this Security or the Indenture.
Neither the Trustee nor the Paying Agent (as defined on the reverse hereof) shall have any responsibility for any calculation or
conversion in connection with the foregoing.


 


Reference is hereby made to the further
provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect

 “Trustee,” which term includes any successor trustee under the Indenture), and Supplemental Indenture No. 9,
dated as of May 14, 2020 (herein called the “Supplemental Indenture”), among the Company, the Trustee, Elavon

Indenture No. 9”), and together with the Base Indenture, the “Indenture”), 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 of this series
and of the terms upon which the Securities of this series 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 €[●].


 


Optional Redemption 


 


At any time prior to the Par Call Date (as
defined below), the Company may redeem some or all of the Securities of this series at its option, in each case at the Company’s
option, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series to be
redeemed; and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest
accrued to the Redemption Date) on the Securities of this series to be redeemed discounted to the Redemption Date on an annual
basis (ACTUAL/ACTUAL (ICMA)) at the applicable Comparable Government Bond Rate plus 25 basis points.


 


The Company will pay accrued and unpaid
interest on the principal amount of the Securities of this series being redeemed to, but excluding, the Redemption Date.


 


In addition, at any time on or after the
Par Call Date, the Company may redeem some or all of the Securities of this series at its option at a redemption price equal to
100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest on the principal
amount of Securities of this series being redeemed to, but excluding, the Redemption Date. If the Company has given notice as provided
in the Indenture and funds for the redemption of any Securities of this series called for redemption have been made available on
the Redemption Date in accordance with the Indenture, such Securities will cease to bear interest on the date fixed for redemption.
Thereafter, the only right of the Holders of such Securities will be to receive payment of the redemption price.


 


The Company will give notice of any optional
redemption to and through Euroclear or Clearstream for communication by them to the Holders of interests in the Securities not
more than 60 nor less than 15 days prior to the Redemption Date. The notice of redemption will specify, among other items, the
Redemption Date, redemption price, the principal amount of the Securities of this series to be redeemed and the place or places
that payment will be made upon surrender of the Securities of this series to be redeemed. Any redemption or notice of redemption
may, at the Company’s discretion, be subject to one or more conditions precedent, and, at the Company’s discretion,
the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied. The Company shall provide
written notice to the Trustee prior to the close of business two business days prior to the Redemption Date if any such redemption
has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of Securities in the same
manner in which the notice of redemption was given.

The Company will
notify the Trustee at least 30 days prior to the Redemption Date fixed by the Company (or such shorter period as is satisfactory
to the Trustee) of the aggregate principal amount of the Securities of this series to be redeemed and their Redemption Date. If
less than all of the Securities of this series are to be redeemed at any time, the Securities will be selected in accordance with
the rules of Euroclear and Clearstream (to be reflected in the records of Euroclear and Clearstream as either a pool factor or
a reduction in nominal amount, at their discretion).

ABBVIE INC., a corporation duly organized

under the Indenture and Supplemental Indenture hereinafter referred to), for value received, hereby promises to pay to USB Nominees
(UK) Limited, as nominee of Elavon Financial Services DAC, as common depositary (the “Common Depositary”) for
Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule
of Exchanges attached hereto, on November 15, 2028 (the “Maturity Date”), and to pay interest thereon from the
most recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”) on
the 2.625% Senior Notes due 2028 issued by Allergan that were accepted in the Exchange Offers, annually on November 15 (the
 “Interest Payment Date”), with the first interest payment to be made on November 15, 2020, at the rate of 2.625%
per annum, until the principal and any unpaid and accrued interest are paid or duly provided for.


 


Interest on the Securities shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Securities, but excluding the next following Interest Payment Date. This payment
convention is referred to as ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the International Capital Market Association).


 


The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is the clearing system
business day (which, for these purposes, is a day on which Euroclear and Clearstream settle payments in euro) immediately prior
to the relevant Interest Payment Date (such day, the “Record Date”). For purposes of this Security, “Business
Day” means any day, other than a Saturday or Sunday, (i) which is not a day on which banking institutions in New York,

Payments of principal of, and premium, if
any, and interest on, this Security, including payments made upon any redemption of this Security, shall be made by wire transfer
of immediately available funds in euro. If the euro is unavailable to the Company due to the imposition of exchange controls or
other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro
is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or
for the settlement of transactions by public institutions or within the international banking community, then all payments in respect
of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such circumstances,
the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal Reserve Board
as of the close of business on the second business day prior to the relevant payment date, or in the event the U.S. Federal Reserve
Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate available on or
prior to the second business day prior to the relevant payment date as determined by the Company in its sole discretion. Any payment
in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default under this Security or the Indenture.
Neither the Trustee nor the Paying Agent (as defined on the reverse hereof) shall have any responsibility for any calculation or
conversion in connection with the foregoing.


 


Reference is hereby made to the further
provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect
as if set forth at this place.


 


Unless the certificate of authentication
hereon has been executed by the Trustee referred to herein by manual signature, this Security shall not be entitled to any benefit

At any time prior to the Par Call Date (as
defined below), the Company may redeem some or all of the Securities of this series at its option, in each case at the Company’s
option, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series to be
redeemed; and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest
accrued to the Redemption Date) on the Securities of this series to be redeemed discounted to the Redemption Date on an annual
basis (ACTUAL/ACTUAL (ICMA)) at the applicable Comparable Government Bond Rate plus 35 basis points.


 


The Company will pay accrued and unpaid
interest on the principal amount of the Securities of this series being redeemed to, but excluding, the Redemption Date.


 


In addition, at any time on or after the

100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest on the principal

in the Indenture and funds for the redemption of any Securities of this series called for redemption have been made available on
the Redemption Date in accordance with the Indenture, such Securities will cease to bear interest on the date fixed for redemption.
Thereafter, the only right of the Holders of such Securities will be to receive payment of the redemption price.

Redemption Date, redemption price, the principal amount of the Securities of this series to be redeemed and the place or places

may, at the Company’s discretion, be subject to one or more conditions precedent, and, at the Company’s discretion,
the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied. The Company shall provide
written notice to the Trustee prior to the close of business two business days prior to the Redemption Date if any such redemption

ABBVIE INC., a corporation duly organized
and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person
under the Indenture and Supplemental Indenture hereinafter referred to), for value received, hereby promises to pay to USB Nominees
(UK) Limited, as nominee of Elavon Financial Services DAC, as common depositary (the “Common Depositary”) for
Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”), or registered
assigns, the principal sum of [●] euro (€[●]), or such other principal sum as may be indicated on the Schedule
of Exchanges attached hereto, on June 1, 2029 (the “Maturity Date”), and to pay interest thereon from the most
recent date on which interest has been paid or duly provided for by Allergan Funding SCS (“Allergan”) on the
2.125% Senior Notes due 2029 issued by Allergan that were accepted in the Exchange Offers, annually on June 1 (the “Interest
Payment Date”), with the first interest payment to be made on June 1, 2020, at the rate of 2.125% per annum, until the
principal and any unpaid and accrued interest are paid or duly provided for.


 


Interest on the Securities shall be determined
on the basis of the actual number of days in the period for which interest is being calculated, and including the last date on
which interest was paid or duly provided for on the Securities, but excluding the next following Interest Payment Date. This payment
convention is referred to as ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the International Capital Market Association).


 


The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close of business on the date that is the clearing system
business day (which, for these purposes, is a day on which Euroclear and Clearstream settle payments in euro) immediately prior
to the relevant Interest Payment Date (such day, the “Record Date”). For purposes of this Security, “Business
Day” means any day, other than a Saturday or Sunday, (i) which is not a day on which banking institutions in New York,
New York or London are authorized or required by law or executive order to close and (ii) on which the Trans European Automated

Payments of principal of, and premium,
if any, and interest on, this Security, including payments made upon any redemption of this Security, shall be made by wire transfer
of immediately available funds in euro. If the euro is unavailable to the Company due to the imposition of exchange controls or
other circumstances beyond the Company’s control (including the dissolution of the European Monetary Union) or if the euro
is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency
or for the settlement of transactions by public institutions or within the international banking community, then all payments
in respect of this Security shall be made in U.S. Dollars until the euro is again available to the Company or so used. In such
circumstances, the amount payable on any date in euro shall be converted into U.S. Dollars at the rate mandated by the U.S. Federal
Reserve Board as of the close of business on the second business day prior to the relevant payment date, or in the event the U.S.
Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. Dollar/euro exchange rate
available on or prior to the second business day prior to the relevant payment date as determined by the Company in its sole discretion.
Any payment in respect of this Security so made in U.S. Dollars shall not constitute an Event of Default under this Security or
the Indenture. Neither the Trustee nor the Paying Agent (as defined on the reverse hereof) shall have any responsibility for any
calculation or conversion in connection with the foregoing.


 


Reference is hereby made to the further
provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect
as if set forth at this place.


 


Unless the certificate of authentication
hereon has been executed by the Trustee referred to herein by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

and of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. This Security is one

Optional Redemption 


 


At any time prior to the Par Call Date (as
defined below), the Company may redeem some or all of the Securities of this series at its option, in each case at the Company’s
option, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Securities of this series to be
redeemed; and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest
accrued to the Redemption Date) on the Securities of this series to be redeemed discounted to the Redemption Date on an annual
basis (ACTUAL/ACTUAL (ICMA)) at the applicable Comparable Government Bond Rate plus 30 basis points.


 


The Company will pay accrued and unpaid
interest on the principal amount of the Securities of this series being redeemed to, but excluding, the Redemption Date.


 


In addition, at any time on or after the
Par Call Date, the Company may redeem some or all of the Securities of this series at its option at a redemption price equal to
100% of the principal amount of the Securities of this series to be redeemed, plus accrued and unpaid interest on the principal

such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders
