and to be bound thereby. However, to the extent any provision of the 2023 Notes conflicts with the express provisions of this Supplemental
Indenture, the provisions of this Supplemental Indenture shall govern and be controlling.

 

Section

to time endorsed thereon and that the aggregate principal amount of the 2023 Notes of the applicable series then Outstanding
represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any
endorsement of a Global 2023 Note to reflect the amount of any increase or decrease in the aggregate principal amount of the 2023

these officers on the 2023 Notes may be manual or facsimile or by way of a digital signature as provided in Section 1.02
hereof. Typographical and other minor errors or defects in any signature shall not affect the validity or enforceability of the 2023
Notes that have been duly authenticated and delivered by the Trustee.

 

Unless otherwise provided
in the 2023 Notes, all of the 2023 Notes shall be dated the date of their authentication.

 

    	 	23	 

     

    

 

Any of the 2023 Notes bearing
the manual, facsimile or digital signatures of individuals who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such
2023 Notes or did not hold such offices at the date of such 2023 Notes.

 

At any time and from time
to time after the execution and delivery of this Supplemental Indenture, the Company may deliver the 2023 Notes to the Trustee for authentication,
together with an Authentication Order with respect to such 2023 Notes, and the Trustee shall, upon receipt of such Authentication Order,
in accordance with procedures acceptable to the Trustee set forth in the Authentication Order, and subject to the provisions hereof and
of the Base Indenture, authenticate and deliver such 2023 Notes to such recipients as may be specified from time to time pursuant to such
Authentication Order. The material terms of such 2023 Notes shall be determinable by reference to such Authentication Order and procedures.
If provided for in such procedures, such Authentication Order may authorize authentication and delivery of such 2023 Notes pursuant to
oral instructions from the Company or any duly authorized agent of the Company, which instructions shall be promptly confirmed in writing.
In authenticating such 2023 Notes and accepting the additional responsibilities under this Supplemental Indenture in relation to such
2023 Notes, the Trustee shall be entitled to receive, and (subject to the provisions of Section 6.05 of the Base Indenture) shall
be fully protected in relying upon:

 

(1)          an
Officers’ Certificate, certifying as to the authorized forms and terms of the 2023 Notes; and

 

(2)          an
Opinion of Counsel, stating that:

 

(a)          the
forms and terms of such 2023 Notes have been established by and in conformity with the provisions of the Base Indenture and this Supplemental
Indenture; provided that if all such 2023 Notes are not to be issued at the same time, such Opinion of Counsel may state that such
terms will be established in conformity with the provisions of the Base Indenture and this Supplemental Indenture, subject to any conditions
specified in such Opinion of Counsel; and

 

(b)          such
2023 Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified
in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their
terms, subject to bankruptcy, insolvency, moratorium, reorganization, and other laws of general applicability relating to or affecting
the enforcement of creditors’ rights and to general principles of equity;

 

provided,
however, that if all of the 2023 Notes issuable by or pursuant to a Board Resolution of the Company are not to be originally
issued at one time, it shall not be necessary to deliver the Officers’ Certificate or Opinion of Counsel otherwise required pursuant
to this paragraph at or prior to the time of authentication of such 2023 Notes if such documents are delivered at or prior to the time
of authentication upon original issuance of such 2023 Notes to be issued. After the original issuance of such 2023 Notes to be issued,
any separate request by the Company that the Trustee authenticate such 2023 Notes for original issuance will be deemed to be a certification
by the Company that it is in compliance with all conditions precedent provided for in the Base Indenture and this Supplemental Indenture
relating to the authentication and delivery of such 2023 Notes.

 

    	 	24	 

     

    

 

None of the 2023 Notes shall
be entitled to any benefit under the Base Indenture or this Supplemental Indenture or be valid or obligatory for any purpose unless there
appears on such 2023 Notes a certificate of authentication executed by the Trustee by manual signature of an authorized signatory, and
such certificate upon any of the 2023 Notes shall be conclusive evidence, and the only evidence, that such 2023 Notes have been duly authenticated
and delivered hereunder.

 

Section
2.07. CUSIP Number. The Company in issuing the 2023 Notes may use Committee on Uniform Security Identification
Procedures (“CUSIP”) numbers (if then generally in use), and, if so, the Trustee will use CUSIP numbers in
notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as
to the correctness of such numbers either as printed on the 2023 Notes or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the 2023 Notes, and any such redemption will not be
affected by any defect in or the omission of such numbers. The Company will promptly notify the Trustee in writing of any change in
the CUSIP numbers.

 

Section
2.08. Issuance of Additional 2023 Notes. The Company will be entitled, upon delivery of an Officer’s
Certificate and an Opinion of Counsel, to issue Additional 2023 Notes under this Supplemental Indenture which will have identical
terms as the Initial 2023 Notes issued on the date hereof, other than with respect to the date of issuance and issue price. The
Initial 2023 Notes issued on the date hereof and any Additional 2023 Notes issued will be treated as a single class for all purposes
under this Supplemental Indenture. With respect to any Additional 2023 Notes, the Company will set forth in a Board Resolution and
an Officer’s Certificate, a copy of each which will be delivered to the Trustee, the following information:

 

(a)          the
aggregate principal amount of such Additional 2023 Notes to be authenticated and delivered pursuant to this Supplemental Indenture; and

 

(b)          the
issue price, the issue date and the CUSIP number of such Additional 2023 Notes.

Limitation on Sale and Leaseback Transactions. The Company will not, and will not permit any of its Restricted Subsidiaries
to, enter into any sale and leaseback transaction; provided that the Company or any Guarantor may enter into a sale and leaseback

hereof and (ii) the gross cash proceeds of such sale and leaseback transaction are at least equal to the fair market value (as determined
in good faith by the Board of Directors of the Company and set forth in an Officers’ Certificate delivered to the Trustee) of the

(ii)            the
purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed,

(iii)           that
any 2023 Note not tendered will continue to accrue interest;

Holders electing to have any 2023 Notes purchased pursuant to a Change of Control Offer will be required to surrender the 2023 Notes,

at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment

The Company shall comply with
the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of 2023 Notes in connection with a Change of Control Triggering
Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 5.04, the Company will
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 5.04
by virtue of such conflict.

 

    	 	32	 

     

    

 

(b)            On
the Change of Control Payment Date, the Company shall, to the extent lawful, (i) accept for payment all 2023 Notes or portions thereof
properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control
Payment in respect of all 2023 Notes or portions thereof properly tendered and (iii) deliver or cause to be delivered to the Trustee
(by book entry) the 2023 Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of

if any; provided, that each such 2023 Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess
thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change
of Control Payment Date.

manner, at the times and otherwise in compliance with the requirements set forth in this Section 5.04 and all other provisions of
this Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all 2023 Notes properly tendered

time of such creation or acquisition) shall become a Guarantor and execute and deliver to the Trustee a joinder to this Supplemental Indenture
pursuant to which such Subsidiary shall agree to guarantee the Company’s obligations under the 2023 Notes, except for all Subsidiaries
that have properly been designated as Unrestricted Subsidiaries or Designated Non-Guarantors in accordance with this Supplemental Indenture
for so long as they continue to constitute Unrestricted Subsidiaries or Designated Non-Guarantors. The form of such joinder to this Supplemental
Indenture is attached hereto as Exhibit B.

 

Section 5.06.
Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. The Board of Directors of the Company may redesignate
any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

(Back of 2023 Note)

 

0.737%
Senior Notes due 2023

 

Capitalized terms used herein have the meanings
assigned to them in the Supplemental Indenture referred to below unless otherwise indicated.

 

1.            Interest.
AmerisourceBergen Corporation, a Delaware corporation (the “Company”), promises
to pay interest on the principal amount of this 2023 Note at 0.737% per annum from the date hereof until maturity. The Company will pay
interest semi-annually on March 15 and September 15 of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an “Interest Payment Date”). Interest on the 2023 Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing
Default in the payment of interest, and if this 2023 Note is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest will accrue from such next succeeding Interest Payment Date; provided, further,
that the first Interest Payment Date will be September 15, 2021. The Company will pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the 2023 Notes
to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments
of interest at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

 

2.            Method
of Payment. The Company will pay interest on
the 2023 Notes (except defaulted interest) to the Persons who are registered Holders of 2023 Notes at the close of business on the March 1
or September 1 next preceding the Interest Payment Date, even if such 2023 Notes are canceled after such record date and on or before
such Interest Payment Date, except as provided in Section 3.07 of the Base Indenture with respect to defaulted interest. Principal,
premium, if any, and interest on the 2023 Notes will be payable at the office or agency of the Paying Agent and Registrar within the City
of Philadelphia in the Commonwealth of Pennsylvania or, at the option of the Company, payment of interest may be made by check mailed
to the Holders of the 2023 Notes at their respective addresses set forth in the register of Holders of 2023 Notes; provided that
all payments of principal, premium and interest with respect to 2023 Notes, the Holders of which have given wire transfer instructions
to the Trustee, will be required to be made by wire transfer of immediately available funds to the accounts specified by the Holders thereof.
Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts.

 

3.            Paying
Agent and Registrar. Initially, U.S. Bank National
Association, the Trustee under the Indenture (as defined below), will act as Paying Agent and Registrar. The Company may change any Paying
Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

 

4.            Indenture.
This 2023 Note is one of a duly authenticated series of securities of the Company issued and to be issued in one or more series under
an indenture (the “Base Indenture”), dated as of November 19, 2009, between the Company and the Trustee, as supplemented
and amended by the Tenth Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture,
the “Indenture”), dated as of March 30, 2021, among the Company and the Trustee. The terms of the 2023 Notes include
those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The 2023 Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for
a statement of such terms. To the extent any provision of this 2023 Note conflicts with the express provisions of the Indenture, the provisions
of this 2023 Note will govern and be controlling. The Company will be entitled to issue Additional 2023 Notes pursuant to Section 2.08
of the Supplemental Indenture.

 

    		A-3	 

     

    

 

5.            Optional
Redemption. (a) Except as set forth in Paragraph 5(b), the Company shall have
the option to redeem the 2023 Notes, in whole or in part, at any time and from time to time prior to the Par Call Date at a Redemption
Price (expressed as percentage of principal amount) equal to the greater of:

thereon, if any, to the applicable Redemption Date.

 

(b)          On

to time, at a Redemption Price (expressed as percentage of principal amount) equal to 100% of the principal amount of the 2023 Notes to

(i)            the
Acquisition is not consummated on or prior to January 6, 2022; or

 

(ii)            if
prior to January 6, 2022, the Share Purchase Agreement is terminated, other than in connection with the consummation of the Acquisition.

 

(b)            If
an Acquisition Termination Redemption Event occurs, the Company shall redeem all of the aggregate principal amount of the outstanding
2023 Notes on the date no later than the tenth calendar day following the earlier to occur of (i) January 6, 2022 or (ii) the
date that the Share Purchase Agreement is terminated, other than in connection with the consummation of the Acquisition (the “Acquisition

Certificate and the Trustee shall not be responsible for any determination of an Acquisition Termination Redemption Event.

 

    		A-4	 

     

    

 

(c)          Upon
an Acquisition Termination Redemption Event, the Company shall pay the sum of 101% of the aggregate principal amount of the 2023 Notes
(the “Acquisition Termination Redemption Price”), plus, accrued and unpaid interest, if any, to, but excluding,
the Acquisition Termination Redemption Date. Notwithstanding the foregoing, installments of interest on the 2023 Notes that are due and

in the payment of the Acquisition Termination Redemption Price and accrued interest, if any. On or before the Acquisition Termination
Redemption Date for the 2023 Notes, the Company shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the Acquisition
Termination Redemption Price of the 2023 Notes to be redeemed on the Acquisition Termination Redemption Date, and (except if the Acquisition
Termination Redemption Date shall be an Interest Payment Date) accrued interest, if any.

 

(e)           Notice
of an Acquisition Termination Redemption shall be mailed by the Company to the Holders, with a copy to the Trustee, no later than five
Business Days following the Acquisition Termination Redemption Event (an “Acquisition Termination Redemption Notice”).
The Acquisition Termination Redemption Notice shall state the information set forth in, and shall be provided in accordance with Section 11.04
of the Base Indenture. Notice of an Acquisition Termination Redemption having been given as provided in the Indenture, the 2023 Notes
called for an Acquisition Termination Redemption shall, on the Acquisition Termination Redemption Date, become due and payable at the
Acquisition Termination Redemption Price, and accrued and unpaid interest, if any, to, but excluding, the Acquisition Termination Redemption
Date; provided that such Acquisition Termination Redemption Date shall not be specified to occur earlier than the date that is 5 Business
Days after the date on which the Acquisition Termination Redemption Notice is delivered.

 

(f)            Except

7.            Repurchase
at Option of Holder. Upon the occurrence of a
Change of Control Triggering Event, unless the Company has exercised its right to redeem the 2023 Notes as described in Paragraph 5 hereof
within 60 days after the Change of Control Triggering Event, each Holder shall have the right to require the Company to purchase all or
a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s 2023 Notes (the “Change
of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any,
to the date of purchase (the “Change of Control Payment”), subject to the rights of the Holders of the 2023 Notes on
the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following the date upon which the
Change of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after public announcement
of the pending Change of Control, the Company shall send, by first class mail, a notice to each Holder of the 2023 Notes, with a copy
to the Trustee, which notice shall govern the terms of the Change of Control Offer, describing the transaction or transactions that constitute
the Change of Control Triggering Event and setting forth the procedures governing the Change of Control Offer as required by Section 5.04
of the Supplemental Indenture.

 

    		A-5	 

     

    

 

8.            Notice
of Redemption. For purposes of paragraph 5 only,
notice of redemption will be mailed at least 10 days but not more than 60 days before the Redemption Date to each Holder whose 2023 Notes
are to be redeemed at its registered address. 2023 Notes in denominations larger than $2,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the 2023 Notes held by a Holder are to be redeemed. Subject to any conditions precedent that may be
applicable, on and after the Redemption Date interest ceases to accrue on 2023 Notes or portions thereof called for redemption.

 

9.            Denominations,
Transfer, Exchange. The 2023 Notes are in registered
form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 2023 Notes may be transferred or exchanged
as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The
Company need not exchange or transfer any 2023 Note or portion of a 2023 Note selected for redemption, except for the unredeemed portion
of any 2023 Note being redeemed in part. Also, the Company need not exchange or register the transfer of any 2023 Notes for a period of
15 days before a selection of 2023 Notes to be redeemed or during the period between a record date and the corresponding Interest Payment
Date.

 

10.          Persons
Deemed Owners. The registered Holder of a 2023
Note may be treated as its owner for all purposes.

 

11.          Amendment,
Supplement and Waiver.

 

(a)          The
Base Indenture may be amended as provided therein. Subject to certain exceptions, the Supplemental Indenture or the 2023 Notes may be
amended or supplemented with the consent of the Holders of not less than a majority in principal amount of the 2023 Notes (including Additional
2023 Notes under the Supplemental Indenture, if any). The Holders of not less than a majority in principal amount of the 2023 Notes (including
Additional 2023 Notes, if any) may waive any past default with respect to the 2023 Notes and its consequences, except a default not theretofore
cured in the payment of principal, premium, if any, or interest, if any, on the 2023 Notes (except a payment default resulting from an
acceleration that has been rescinded), or in respect of a covenant or provision in Article 4 of the Supplemental Indenture that cannot
be modified or amended without the consent of the Holder of each 2023 Note.

 

    		A-6	 

     

    

 

(b)            Without
the consent of any Holder of a 2023 Note, the Supplemental Indenture or the 2023 Notes may be amended or supplemented:

the covenants, agreements and obligations of the Company pursuant to Article 6 of the Supplemental Indenture; or

 

(ii)            to
add to the covenants of the Company such further covenants, restrictions or conditions for the protection of the Holders of the 2023 Notes
as the Company and the Trustee shall consider to be for the protection of the Holders of the 2023 Notes or to surrender any right or power
therein conferred upon the Company; or

 

(iii)          to
cure any ambiguity, to correct or supplement any provision therein which may be inconsistent with any other provision therein or in any
supplemental indenture thereto, or to make any other provisions with respect to matters or questions arising under the Supplemental Indenture
that do not adversely affect the interests of the Holders of the 2023 Notes in any material respect; or

 

(iv)          to
add to the Supplemental Indenture such provisions as may be expressly permitted by the TIA, excluding, however, the provisions referred

in any similar federal statute hereafter enacted; or

 

(v)           to

Notes and to add to or change any of the provisions of the Supplemental Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, pursuant to Section 6.11 of the Base Indenture; or

 

(ix)           to
add any additional Events of Default in respect of the 2023 Notes; or

 

(x)            to
comply with the requirements of the Commission in connection with the qualification of the Supplemental Indenture under the TIA; or

conform the text of the Supplemental Indenture or the 2023 Notes to any provision of the “Description of Notes” section of
the Company’s Prospectus Supplement dated March 25, 2021, relating to the initial offering
of the 2023 Notes, to the extent that such provision in the “Description of Notes” was intended to be a verbatim recitation
of a provision of the Supplemental Indenture, the 2023 Notes; or

it to be remedied and stating that such notice is a “Notice of Default” hereunder;

 

(iv)          the
entry of an order for relief against the Company or any of its Significant Subsidiaries or any group of its Restricted Subsidiaries that,

their inability to pay their debts generally as they become due, or the taking of corporate action by the Company, the Significant Subsidiary
or such group of Restricted Subsidiaries in furtherance of any such action;

 

    		A-8	 

     

    

 

(vi)          failure
by the Company or any of its Restricted Subsidiaries to comply with Section 5.04 of the Supplemental Indenture, and continuance of
such default for a period of 30 days after there has been given, by registered or certified mail, to the Company by the Trustee or to

(vii)         failure

(viii)        default
under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness
for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of the Supplemental Indenture, which
(i) is caused by the failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of
the grace period provided in such Indebtedness on the date of such default (a “Payment Default”), or (ii) results
in the actual acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of such Indebtedness,

any amount covered by insurance); or

 

(x)            to
the extent a Guarantee with respect to the 2023 Notes is provided pursuant to Section 5.05 of the Supplemental Indenture, except
as permitted by the Supplemental Indenture, any such Guarantee is held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm
its obligations under such Guarantee.

 

If
any Event of Default occurs and is continuing, the Trustee may declare all the 2023 Notes to be due and payable immediately, and upon
receipt of written instructions from the Holders of at least 25% in principal amount of the then outstanding 2023 Notes, the Trustee will
declare all the 2023 Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain
events of bankruptcy or insolvency, with respect to the Company or any Significant Subsidiary or any group of Restricted Subsidiaries
that, taken as a whole, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law, all outstanding
2023 Notes will become due and payable without further action or notice. Holders may not enforce the Supplemental Indenture or the 2023
Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount
of the 2023 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2023 Notes
notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or
Event of Default relating to the payment of principal or interest. The Holders of a majority in aggregate principal amount of the 2023
Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2023 Notes waive any existing Default or Event
of Default and its consequences under the Supplemental Indenture except a continuing Default or Event of Default in the payment of interest
on, or the principal of, the 2023 Notes or as otherwise provided under Section 11. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event
of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

13.          Trustees
Dealings With Company. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise
deal with the Company or its Affiliates, as if it were not the Trustee.

 

14.          No
Recourse Against Others. A director, officer,
employee, incorporator or stockholder, of the Company, as such, shall not have any liability for any obligations of the Company under
the 2023 Notes or the Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of 2023 Notes by accepting a 2023 Note waives and releases all such liability. The waiver and release are part of the consideration
for the issuance of the 2023 Notes.

 

15.          Authentication.
This 2023 Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants

(= Uniform Gifts to Minors Act).

 

17.          CUSIP
Numbers. Pursuant to a recommendation promulgated
by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the 2023 Notes and
the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of
such numbers either as printed on the 2023 Notes or as contained in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon. The Company will furnish to any Holder upon written request and without charge a copy of the Base
Indenture or the Supplemental Indenture. Requests may be made to:

INDENTURE 

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

 

This JOINDER TO TENTH SUPPLEMENTAL
INDENTURE (this “Joinder”), dated as of _____________, 20__, among ____________________ (the “Guarantor[s]”),
[each] a subsidiary of AmerisourceBergen Corporation (or [its/their] permitted successor[s]), a Delaware corporation (the “Company”),
the Company and U.S. Bank National Association, as trustee under the Tenth Supplemental Indenture referred to below (the “Trustee”).

 

Recitals

 

The
Company has heretofore executed and delivered to the Trustee an indenture (the “Base Indenture”), dated as of November 19,
2009, between the Company and the Trustee, as amended and supplemented by a tenth supplemental indenture thereto (the “Tenth
Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of March 30,
2021, among the Company and the Trustee, providing for the original issuance of an aggregate principal amount of $1,525 million ($1,525,000,000)
of the Company’s 0.737% Senior Notes due 2023 (the “2023 Notes”).

 

The Tenth Supplemental Indenture
provides that under certain circumstances the Guarantor[s] will execute and deliver to the Trustee a joinder to Tenth Supplemental Indenture
pursuant to which the Guarantor[s] will unconditionally guarantee all of the Company’s Obligations under the 2023 Notes and the
Indenture on the terms and conditions set forth herein (the “2023 Note Guarantee”).

 

Pursuant to Section 4.01
of the Tenth Supplemental Indenture, the Trustee is authorized to execute and deliver this Joinder.

 

NOW THEREFORE, in consideration
of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guarantor[s] and the
Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the 2023 Notes as follows:

 

1.            Capitalized
Terms. Capitalized terms used herein without definition will have the meanings assigned to them in the Tenth Supplemental Indenture.

 

2.            Joinder.
By execution hereof, the Guarantor[s] hereby agree[s] as of the date hereof, to become and [is/are] made
[a party/parties] to the Tenth Supplemental Indenture and for all purposes under the Tenth Supplemental Indenture, each Guarantor shall
be included within the term “Guarantor” (as defined in the Tenth Supplemental Indenture). The undersigned hereby agrees
to be bound by all of the agreements, terms, conditions and restrictions of this Joinder as applicable to [it][them]; and, further, adopt[s]
and agree[s] to be bound by all of the agreements, terms, conditions and restrictions applicable to a “Guarantor” as such
term is defined in the Tenth Supplemental Indenture; and, further, authorize[s] the Trustee to attach this signature page to the
Tenth Supplemental Indenture in order to make the Guarantor a party to the Tenth Supplemental Indenture.

 

    	 	B-1	 

     

    

 

3.            Guarantee.
Subject to this Joinder, the Guarantor[s] hereby, jointly and severally with all other Guarantors, if any, unconditionally guarantee[s]
to each Holder of the 2023 Notes authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of the Tenth Supplemental Indenture, the 2023 Notes and the obligations of the Company thereunder,
that:

 

(a)            the
principal of and interest on the 2023 Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption,
mandatory repurchase or otherwise, and interest on the overdue principal of and interest on the 2023 Notes, if any, if lawful, and all
other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and

 

(b)            in
case of any extension of time of payment or renewal of any 2023 Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration, redemption,
mandatory repurchase or otherwise.

 

Failing payment when due of any amount so guaranteed
or any performance so guaranteed for whatever reason, the Guarantor[s] shall be jointly and severally obligated with all other Guarantors,
if any, to pay the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.

 

The
Guarantor[s] agree[s] that [their][its] obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability
of the 2023 Notes or the Tenth Supplemental Indenture, the absence of any action to enforce the same, any waiver or consent by
any Holder of the 2023 Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of any Guarantor.
Each Guarantor waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that
the Guarantee in this Section 3 shall not be discharged except by complete performance of the obligations contained in the 2023 Notes,
the Tenth Supplemental Indenture and this Joinder.

 

If any Holder or the Trustee is required by any
court or otherwise to return to the Company, the Guarantor[s] or any custodian, trustee, liquidator or other similar official acting in
relation to either the Company or the Guarantor[s], any amount paid by either to the Trustee or such Holder, this 2023 Note Guarantee,
to the extent theretofore discharged, shall be reinstated in full force and effect.

 

Each Guarantor agrees that it shall not be entitled
to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on
the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 5.02 of the
Base Indenture or Section 3.01 of the Tenth Supplemental Indenture for the purposes of this 2023 Note Guarantee, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (ii) in
the event of any declaration of acceleration of such obligations as provided in Section 5.02 of the Base Indenture or Section 3.01
of the Tenth Supplemental Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor
for the purpose of this 2023 Note Guarantee. Each Guarantor shall have the right to seek contribution from any non-paying Guarantor so
long as the exercise of such right does not impair the rights of the Holders under this 2023 Note Guarantee.

 

    	 	B-2	 

     

    

 

4.            Limitation
on Guarantor Liability. Each Guarantor, and by its acceptance of 2023 Notes, each Holder, hereby confirms that it is the intention
of all such parties that the 2023 Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any 2023 Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantor[s] hereby
irrevocably agree that the obligations of any Guarantor will, after giving effect to such maximum amount and all other contingent and
fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive
contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under
this Article 8, result in the obligations of such Guarantor under its 2023 Note Guarantee not constituting a fraudulent transfer
or conveyance.

 

5.            Execution
and Delivery of 2023 Note Guarantee. To evidence its 2023 Note Guarantee, each Guarantor hereby agrees that a notation of such
2023 Note Guarantee substantially in the form included in Annex A to this Joinder shall be endorsed by an Officer of such Guarantor
and that this Joinder shall be executed on behalf of such Guarantor by its President or one of its Vice Presidents.

 

Each Guarantor hereby agrees that its 2023 Note
Guarantee shall remain in full force and effect notwithstanding any failure to endorse a notation of such 2023 Note Guarantee.

 

6.            Guarantors
May Consolidate, etc., on Certain Terms. Except as otherwise provided in Section 7 of this Joinder, no Guarantor
may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not
such Guarantor is the surviving Person) another Person whether or not affiliated with such Guarantor unless:

 

(a)            subject
to Section 7 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger (if other than a Guarantor or the Company) unconditionally assumes all the obligations of such Guarantor, pursuant
to a supplemental indenture in form and substance reasonably satisfactory to the Trustee or by operation of law, under the 2023 Notes,
the Tenth Supplemental Indenture and this 2023 Note Guarantee on the terms set forth herein or therein; and

 

(b)            immediately
after giving effect to such transaction, no Default or Event of Default exists.

 

In case of any such consolidation, merger, sale
or conveyance and upon the assumption by the successor Person, by operation of law or by supplemental indenture, executed and delivered
to the Trustee and satisfactory in form to the Trustee, of this 2023 Note Guarantee endorsed upon the 2023 Notes and the due and punctual
performance of all of the covenants and conditions of the Tenth Supplemental Indenture to be performed by each Guarantor, such successor
Person shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as a Guarantor. Such
successor Person thereupon may cause to be signed any or all of the 2023 Note Guarantees to be endorsed upon all of the 2023 Notes issuable
hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the 2023 Note Guarantees so issued
shall in all respects have the same legal rank and benefit under the Tenth Supplemental Indenture as the 2023 Note Guarantees theretofore
and thereafter issued in accordance with the terms of the Tenth Supplemental Indenture as though all of such 2023 Note Guarantees had
been issued at the date of the execution hereof.

 

    	 	B-3	 

     

    

 

Except as set forth in Articles 8 and 10 of the
Base Indenture and Articles 5 and 6 of the Tenth Supplemental Indenture, and notwithstanding clauses (a) and (b) above in this
Section 6, nothing contained in the Tenth Supplemental Indenture or in any of the 2023 Notes shall prevent any consolidation or merger
of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as
an entirety or substantially as an entirety to the Company or another Guarantor.

 

7.            Releases.
A Guarantor will be released and relieved of its obligations under the 2023 Note Guarantee upon the occurrence of any of the events
set forth in this Section 7.

 

(i)            In
the event of a sale or other disposition of all of the assets of such Guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all of the Capital Stock of such Guarantor, in each case to a Person that is not (either before or after giving
effect to such transactions) a Subsidiary of the Company if, after giving effect to such transaction, neither the Person acquiring such
Capital Stock nor such Guarantor has outstanding or guarantees any Specified Indebtedness, then such Guarantor (in the event of a sale
or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation
acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will
be released and relieved of its obligations under its 2023 Note Guarantee.

 

(ii)            In
the event the Company designates such Guarantor to be an Unrestricted Subsidiary in accordance with the Tenth Supplemental Indenture,
such Guarantor shall be released and relieved of its obligations under its 2023 Note Guarantee.

 

(iii)            In
the event such Guarantor shall cease (or simultaneously with the release of its Guarantee hereunder shall cease) to have outstanding or
guarantee any Specified Indebtedness, such Guarantor shall be released and relieved of its obligations under its 2023 Note Guarantee.

 

Upon delivery by the Company to the Trustee of
an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in
accordance with the provisions of the Tenth Supplemental Indenture, or upon delivery by the Company to the Trustee of an Officers’
Certificate to the effect that the applicable Guarantor has ceased (or simultaneously with the release of its 2023 Note Guarantee hereunder
shall cease) to have outstanding or guarantee any Specified Indebtedness or that the applicable Guarantor has been designated as an Unrestricted
Subsidiary in accordance with the provisions of the Tenth Supplemental Indenture, the Trustee shall execute any documents reasonably required
in order to evidence the release of any Guarantor from its obligations under its 2023 Note Guarantee.

 

    	 	B-4	 

     

    

 

Any Guarantor not released from its obligations
under its 2023 Note Guarantee shall remain liable for the full amount of principal of and interest on the 2023 Notes and for the other
obligations of any Guarantor under the Tenth Supplemental Indenture as provided in this Section 7.

 

8.          Governing
Law. THIS JOINDER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

be known as its “2.700% Senior Notes due 2031” (the “2031 Notes”), the form and substance and the terms,

    		23	 

     

    

 

At any time and from time

together with an Authentication Order with respect to such 2031 Notes, and the Trustee shall, upon receipt of such Authentication Order,
in accordance with procedures acceptable to the Trustee set forth in the Authentication Order, and subject to the provisions hereof and
of the Base Indenture, authenticate and deliver such 2031 Notes to such recipients as may be specified from time to time pursuant to such

If provided for in such procedures, such Authentication Order may authorize authentication and delivery of such 2031 Notes pursuant to
oral instructions from the Company or any duly authorized agent of the Company, which instructions shall be promptly confirmed in writing.
In authenticating such 2031 Notes and accepting the additional responsibilities under this Supplemental Indenture in relation to such

Officers’ Certificate, certifying as to the authorized forms and terms of the 2031 Notes; and

 

(2)           an
Opinion of Counsel, stating that:

 

(a)           the
forms and terms of such 2031 Notes have been established by and in conformity with the provisions of the Base Indenture and this Supplemental
Indenture; provided that if all such 2031 Notes are not to be issued at the same time, such Opinion of Counsel may state that such
terms will be established in conformity with the provisions of the Base Indenture and this Supplemental Indenture, subject to any conditions
specified in such Opinion of Counsel; and

 

(b)           such
2031 Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified
in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their
terms, subject to bankruptcy, insolvency, moratorium, reorganization, and other laws of general applicability relating to or affecting
the enforcement of creditors’ rights and to general principles of equity;

 

provided,
however, that if all of the 2031 Notes issuable by or pursuant to a Board Resolution of the Company are not to be originally
issued at one time, it shall not be necessary to deliver the Officers’ Certificate or Opinion of Counsel otherwise required pursuant
to this paragraph at or prior to the time of authentication of such 2031 Notes if such documents are delivered at or prior to the time
of authentication upon original issuance of such 2031 Notes to be issued. After the original issuance of such 2031 Notes to be issued,
any separate request by the Company that the Trustee authenticate such 2031 Notes for original issuance will be deemed to be a certification
by the Company that it is in compliance with all conditions precedent provided for in the Base Indenture and this Supplemental Indenture
relating to the authentication and delivery of such 2031 Notes.

 

    		24	 

     

    

 

None of the 2031 Notes shall
be entitled to any benefit under the Base Indenture or this Supplemental Indenture or be valid or obligatory for any purpose unless there
appears on such 2031 Notes a certificate of authentication executed by the Trustee by manual signature of an authorized signatory, and
such certificate upon any of the 2031 Notes shall be conclusive evidence, and the only evidence, that such 2031 Notes have been duly authenticated
and delivered hereunder.

 

Section 2.07.

(“CUSIP”) numbers (if then generally in use), and, if so, the Trustee will use CUSIP numbers in notices of redemption
as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the 2031 Notes or as contained in any notice of a redemption and that reliance may be placed only on the
other identification numbers printed on the 2031 Notes, and any such redemption will not be affected by any defect in or the omission
of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP numbers.

 

Section 2.08.
Issuance of Additional 2031 Notes. The Company will be entitled, upon delivery of an Officer’s Certificate and

the date hereof and any Additional 2031 Notes issued will be treated as a single class for all purposes under this Supplemental Indenture.

integral multiple thereof.

 

The Company shall comply with
the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of 2031 Notes in connection with a Change of Control Triggering

comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 5.04
by virtue of such conflict.

manner, at the times and otherwise in compliance with the requirements set forth in this Section 5.04 and all other provisions of
this Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all 2031 Notes properly tendered

(Back of 2031 Note)

 

2.700%
Senior Notes due 2031

 

Capitalized terms used herein have the meanings
assigned to them in the Supplemental Indenture referred to below unless otherwise indicated.

 

1.            Interest.
AmerisourceBergen Corporation, a Delaware corporation (the “Company”), promises
to pay interest on the principal amount of this 2031 Note at 2.700% per annum from the date hereof until maturity. The Company will pay
interest semi-annually on March 15 and September 15 of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an “Interest Payment Date”). Interest on the 2031 Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing
Default in the payment of interest, and if this 2031 Note is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest will accrue from such next succeeding Interest Payment Date; provided, further,
that the first Interest Payment Date will be September 15, 2021. The Company will pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the 2031 Notes
to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments
of interest at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

 

2.            Method
of Payment. The Company will pay interest on
the 2031 Notes (except defaulted interest) to the Persons who are registered Holders of 2031 Notes at the close of business on the March 1
or September 1 next preceding the Interest Payment Date, even if such 2031 Notes are canceled after such record date and on or before
such Interest Payment Date, except as provided in Section 3.07 of the Base Indenture with respect to defaulted interest. Principal,
premium, if any, and interest on the 2031 Notes will be payable at the office or agency of the Paying Agent and Registrar within the City
of Philadelphia in the Commonwealth of Pennsylvania or, at the option of the Company, payment of interest may be made by check mailed
to the Holders of the 2031 Notes at their respective addresses set forth in the register of Holders of 2031 Notes; provided that
all payments of principal, premium and interest with respect to 2031 Notes, the Holders of which have given wire transfer instructions
to the Trustee, will be required to be made by wire transfer of immediately available funds to the accounts specified by the Holders thereof.
Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts.

 

3.            Paying
Agent and Registrar. Initially, U.S. Bank National
Association, the Trustee under the Indenture (as defined below), will act as Paying Agent and Registrar. The Company may change any Paying
Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

 

    A-3

     

    

 

4.            Indenture.
This 2031 Note is one of a duly authenticated series of securities of the Company issued and to be issued in one or more series under
an indenture (the “Base Indenture”), dated as of November 19, 2009, between the Company and the Trustee, as supplemented
and amended by the Eleventh Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture,
the “Indenture”), dated as of March 30, 2021, among the Company and the Trustee. The terms of the 2031 Notes include
those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code Sections 77aaa-77bbbb). The 2031 Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for
a statement of such terms. To the extent any provision of this 2031 Note conflicts with the express provisions of the Indenture, the provisions
of this 2031 Note will govern and be controlling. The Company will be entitled to issue Additional 2031 Notes pursuant to Section 2.08
of the Supplemental Indenture.

 

5.            Optional
Redemption. (a) Except as set forth in Paragraph 5(b), the Company shall have
the option to redeem the 2031 Notes, in whole or in part, at any time and from time to time prior to the Par Call Date at a Redemption
Price (expressed as percentage of principal amount) equal to the greater of:

 

(i)           100%
of the principal amount of the 2031 Notes to be redeemed; or

 

(ii)          as
determined by an Independent Investment Banker, the sum of the present values of the Remaining Scheduled Payments discounted to the Redemption
Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate;

 

in each case plus accrued and unpaid interest
thereon, if any, to the applicable Redemption Date.

 

(b)          On
and after the Par Call Date, the Company shall have the option to redeem the 2031 Notes, in whole or in part at any time and from time
to time, at a Redemption Price (expressed as percentage of principal amount) equal to 100% of the principal amount of the 2031 Notes to
be redeemed, plus accrued and unpaid interest thereon, if any, to the applicable Redemption Date.

 

(c)          Unless
the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the 2031 Notes
or portion thereof called for redemption.

 

(d)          Any
redemption pursuant to this paragraph shall be made pursuant to the provisions of Section 11.01 through Section 11.07 of the
Base Indenture.

 

6.            Mandatory
Redemption.

 

(a) The 2031 Notes shall
be redeemed, in each case, in whole and not in part (an “Acquisition Termination Redemption”) in the event that
(each, an “Acquisition Termination Redemption Event”) either:

 

(i)           the
Acquisition is not consummated on or prior to January 6, 2022; or

 

(ii)          if
prior to January 6, 2022, the Share Purchase Agreement is terminated, other than in connection with the consummation of the Acquisition.

 

    A-4

     

    

 

(b)          If
an Acquisition Termination Redemption Event occurs, the Company shall redeem all of the aggregate principal amount of the outstanding
2031 Notes on the date no later than the tenth calendar day following the earlier to occur of (i) January 6, 2022 or (ii) the
date that the Share Purchase Agreement is terminated, other than in connection with the consummation of the Acquisition (the “Acquisition
Termination Redemption Date”). The Company shall furnish the Trustee with an Officers’ Certificate notifying the Trustee
of the occurrence of such Acquisition Termination Redemption Event. The Trustee shall be fully protected in relying upon such Officers’
Certificate and the Trustee shall not be responsible for any determination of an Acquisition Termination Redemption Event.

 

(c)          Upon
an Acquisition Termination Redemption Event, the Company shall pay the sum of 101% of the aggregate principal amount of the 2031 Notes
(the “Acquisition Termination Redemption Price”), plus, accrued and unpaid interest, if any, to, but excluding,
the Acquisition Termination Redemption Date. Notwithstanding the foregoing, installments of interest on the 2031 Notes that are due and
payable on Interest Payment Dates falling on or prior to an Acquisition Termination Redemption Date shall be payable on the Interest Payment
Date to the Persons in whose name the 2031 Notes are registered at the close of business on the relevant record date according to the
2031 Notes and the Indenture.

 

(d)          Upon
the Acquisition Termination Redemption Date for the 2031 Notes, interest shall cease to accrue on the 2031 Notes unless the Company defaults
in the payment of the Acquisition Termination Redemption Price and accrued interest, if any. On or before the Acquisition Termination
Redemption Date for the 2031 Notes, the Company shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the Acquisition
Termination Redemption Price of the 2031 Notes to be redeemed on the Acquisition Termination Redemption Date, and (except if the Acquisition
Termination Redemption Date shall be an Interest Payment Date) accrued interest, if any.

 

(e)          Notice
of an Acquisition Termination Redemption shall be mailed by the Company to the Holders, with a copy to the Trustee, no later than five
Business Days following the Acquisition Termination Redemption Event (an “Acquisition Termination Redemption Notice”).
The Acquisition Termination Redemption Notice shall state the information set forth in, and shall be provided in accordance with Section 11.04
of the Base Indenture. Notice of an Acquisition Termination Redemption having been given as provided in the Indenture, the 2031 Notes
called for an Acquisition Termination Redemption shall, on the Acquisition Termination Redemption Date, become due and payable at the
Acquisition Termination Redemption Price, and accrued and unpaid interest, if any, to, but excluding, the Acquisition Termination Redemption
Date; provided that such Acquisition Termination Redemption Date shall not be specified to occur earlier than the date that is 5 Business
Days after the date on which the Acquisition Termination Redemption Notice is delivered.

 

(f)           Except
as set forth in Paragraph 6 hereof and Paragraph 7 below, the Company shall not have any mandatory redemption obligation with respect
to the 2031 Notes. The 2031 Notes will not be subject to, nor have the benefit of, a sinking fund.

 

    A-5

     

    

 

 

7.            Repurchase
at Option of Holder. Upon the occurrence of a
Change of Control Triggering Event, unless the Company has exercised its right to redeem the 2031 Notes as described in Paragraph 5 hereof
within 60 days after the Change of Control Triggering Event, each Holder shall have the right to require the Company to purchase all or
a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s 2031 Notes (the “Change
of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any,
to the date of purchase (the “Change of Control Payment”), subject to the rights of the Holders of the 2031 Notes on
the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following the date upon which the
Change of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after public announcement
of the pending Change of Control, the Company shall send, by first class mail, a notice to each Holder of the 2031 Notes, with a copy
to the Trustee, which notice shall govern the terms of the Change of Control Offer, describing the transaction or transactions that constitute
the Change of Control Triggering Event and setting forth the procedures governing the Change of Control Offer as required by Section 5.04
of the Supplemental Indenture.

 

8.            Notice
of Redemption. For purposes of paragraph 5 only,
notice of redemption will be mailed at least 10 days but not more than 60 days before the Redemption Date to each Holder whose 2031 Notes
are to be redeemed at its registered address. 2031 Notes in denominations larger than $2,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the 2031 Notes held by a Holder are to be redeemed. Subject to any conditions precedent that may be
applicable, on and after the Redemption Date interest ceases to accrue on 2031 Notes or portions thereof called for redemption.

 

9.            Denominations,
Transfer, Exchange. The 2031 Notes are in registered
form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 2031 Notes may be transferred or exchanged
as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The
Company need not exchange or transfer any 2031 Note or portion of a 2031 Note selected for redemption, except for the unredeemed portion
of any 2031 Note being redeemed in part. Also, the Company need not exchange or register the transfer of any 2031 Notes for a period of
15 days before a selection of 2031 Notes to be redeemed or during the period between a record date and the corresponding Interest Payment
Date.

 

10.          Persons
Deemed Owners. The registered Holder of a 2031
Note may be treated as its owner for all purposes.

 

11.          Amendment,
Supplement and Waiver.

 

(a)          The
Base Indenture may be amended as provided therein. Subject to certain exceptions, the Supplemental Indenture or the 2031 Notes may be
amended or supplemented with the consent of the Holders of not less than a majority in principal amount of the 2031 Notes (including Additional
2031 Notes under the Supplemental Indenture, if any). The Holders of not less than a majority in principal amount of the 2031 Notes (including
Additional 2031 Notes, if any) may waive any past default with respect to the 2031 Notes and its consequences, except a default not theretofore
cured in the payment of principal, premium, if any, or interest, if any, on the 2031 Notes (except a payment default resulting from an
acceleration that has been rescinded), or in respect of a covenant or provision in Article 4 of the Supplemental Indenture that cannot
be modified or amended without the consent of the Holder of each 2031 Note.

 

    A-6

the covenants, agreements and obligations of the Company pursuant to Article 6 of the Supplemental Indenture; or

 

(ii)           to
add to the covenants of the Company such further covenants, restrictions or conditions for the protection of the Holders of the 2031 Notes
as the Company and the Trustee shall consider to be for the protection of the Holders of the 2031 Notes or to surrender any right or power
therein conferred upon the Company; or

 

(iii)          to
cure any ambiguity, to correct or supplement any provision therein which may be inconsistent with any other provision therein or in any
supplemental indenture thereto, or to make any other provisions with respect to matters or questions arising under the Supplemental Indenture
that do not adversely affect the interests of the Holders of the 2031 Notes in any material respect; or

 

(iv)         to
add to the Supplemental Indenture such provisions as may be expressly permitted by the TIA, excluding, however, the provisions referred

in any similar federal statute hereafter enacted; or

(vii)        to
add to the rights of the Holders of the 2031 Notes; or

Notes and to add to or change any of the provisions of the Supplemental Indenture as shall be necessary to provide for or facilitate the
administration of the trusts hereunder by more than one Trustee, pursuant to Section 6.11 of the Base Indenture; or

 

(ix)          to
add any additional Events of Default in respect of the 2031 Notes; or

 

(x)           to
comply with the requirements of the Commission in connection with the qualification of the Supplemental Indenture under the TIA; or

 

(xi)          to
conform the text of the Supplemental Indenture or the 2031 Notes to any provision of the “Description of Notes” section of
the Company’s Prospectus Supplement dated March 25, 2021, relating to the initial offering
of the 2031 Notes, to the extent that such provision in the “Description of Notes” was intended to be a verbatim recitation
of a provision of the Supplemental Indenture, the 2031 Notes; or

 

(xii)         to
allow any Guarantor to execute a joinder to the Supplemental Indenture and a Guarantee with respect to the 2031 Notes pursuant to such
joinder.

 

    A-7

under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness
for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of
its Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of the Supplemental Indenture, which
(i) is caused by the failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of
the grace period provided in such Indebtedness on the date of such default (a “Payment Default”), or (ii) results
in the actual acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of such Indebtedness,
together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which
has been so accelerated, aggregates $100.0 million or more;

 

(ix)          a
final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company
or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary
and such judgment or judgments remain undischarged for a period (during which execution shall not be effectively stayed pending appeal
(or otherwise stayed)) of 60 days, provided that the aggregate of all such undischarged judgments exceeds $100.0 million (net of
any amount covered by insurance); or

 

(x)           to
the extent a Guarantee with respect to the 2031 Notes is provided pursuant to Section 5.05 of the Supplemental Indenture, except
as permitted by the Supplemental Indenture, any such Guarantee is held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm
its obligations under such Guarantee.

 

If
any Event of Default occurs and is continuing, the Trustee may declare all the 2031 Notes to be due and payable immediately, and upon
receipt of written instructions from the Holders of at least 25% in principal amount of the then outstanding 2031 Notes, the Trustee will
declare all the 2031 Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain
events of bankruptcy or insolvency, with respect to the Company or any Significant Subsidiary or any group of Restricted Subsidiaries
that, taken as a whole, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law, all outstanding
2031 Notes will become due and payable without further action or notice. Holders may not enforce the Supplemental Indenture or the 2031
Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount
of the 2031 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2031 Notes
notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or
Event of Default relating to the payment of principal or interest. The Holders of a majority in aggregate principal amount of the 2031
Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2031 Notes waive any existing Default or Event
of Default and its consequences under the Supplemental Indenture except a continuing Default or Event of Default in the payment of interest
on, or the principal of, the 2031 Notes or as otherwise provided under Section 11. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event
of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

13.          Trustees
Dealings With Company. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise
deal with the Company or its Affiliates, as if it were not the Trustee.

 

14.          No
Recourse Against Others. A director, officer,
employee, incorporator or stockholder, of the Company, as such, shall not have any liability for any obligations of the Company under
the 2031 Notes or the Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder of 2031 Notes by accepting a 2031 Note waives and releases all such liability. The waiver and release are part of the consideration
for the issuance of the 2031 Notes.

 

15.          Authentication.
This 2031 Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

 

16.          Abbreviations.
Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants
by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).

 

17.          CUSIP
Numbers. Pursuant to a recommendation promulgated
by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the 2031 Notes and
the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of
such numbers either as printed on the 2031 Notes or as contained in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon. The Company will furnish to any Holder upon written request and without charge a copy of the Base
Indenture or the Supplemental Indenture. Requests may be made to:

FORM OF JOINDER TO ELEVENTH SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

 

This JOINDER TO ELEVENTH SUPPLEMENTAL
INDENTURE (this “Joinder”), dated as of _____________, 20__, among ____________________ (the “Guarantor[s]”),
[each] a subsidiary of AmerisourceBergen Corporation (or [its/their] permitted successor[s]), a Delaware corporation (the “Company”),
the Company and U.S. Bank National Association, as trustee under the Eleventh Supplemental Indenture referred to below (the “Trustee”).

 

Recitals

 

The
Company has heretofore executed and delivered to the Trustee an indenture (the “Base Indenture”), dated as of November 19,
2009, between the Company and the Trustee, as amended and supplemented by a eleventh supplemental indenture thereto (the “Eleventh
Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of March 30,
2021, among the Company and the Trustee, providing for the original issuance of an aggregate principal amount of $1,000 million ($1,000,000,000)
of the Company’s 2.700% Senior Notes due 2031 (the “2031 Notes”).

 

The
Eleventh Supplemental Indenture provides that under certain circumstances the Guarantor[s] will execute and deliver to the Trustee
a joinder to Eleventh Supplemental Indenture pursuant to which the Guarantor[s] will unconditionally guarantee all of the Company’s
Obligations under the 2031 Notes and the Indenture on the terms and conditions set forth herein (the “2031 Note Guarantee”).

 

Pursuant
to Section 4.01 of the Eleventh Supplemental Indenture, the Trustee is authorized to execute and deliver this Joinder.

 

NOW THEREFORE, in consideration
of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guarantor[s] and the
Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the 2031 Notes as follows:

 

1.             Capitalized
Terms. Capitalized terms used herein without definition will have the meanings assigned to them in the Eleventh Supplemental Indenture.

 

2.             Joinder.
By execution hereof, the Guarantor[s] hereby agree[s] as of the date hereof, to become and [is/are] made
[a party/parties] to the Eleventh Supplemental Indenture and for all purposes under the Eleventh Supplemental Indenture, each Guarantor
shall be included within the term “Guarantor” (as defined in the Eleventh Supplemental Indenture). The undersigned
hereby agrees to be bound by all of the agreements, terms, conditions and restrictions of this Joinder as applicable to [it][them]; and,
further, adopt[s] and agree[s] to be bound by all of the agreements, terms, conditions and restrictions applicable to a “Guarantor”
as such term is defined in the Eleventh Supplemental Indenture; and, further, authorize[s] the Trustee to attach this signature page to
the Eleventh Supplemental Indenture in order to make the Guarantor a party to the Eleventh Supplemental Indenture.

 

    B-1

     

    

 

3.             Guarantee.
Subject to this Joinder, the Guarantor[s] hereby, jointly and severally with all other Guarantors, if any, unconditionally guarantee[s]
to each Holder of the 2031 Notes authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of the Eleventh Supplemental Indenture, the 2031 Notes and the obligations of the Company thereunder,
that:

 

(a)          the
principal of and interest on the 2031 Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption,
mandatory repurchase or otherwise, and interest on the overdue principal of and interest on the 2031 Notes, if any, if lawful, and all
other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all
in accordance with the terms hereof and thereof; and

 

(b)          in
case of any extension of time of payment or renewal of any 2031 Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration, redemption,
mandatory repurchase or otherwise.

 

Failing payment when due of any amount so guaranteed
or any performance so guaranteed for whatever reason, the Guarantor[s] shall be jointly and severally obligated with all other Guarantors,
if any, to pay the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.

 

The
Guarantor[s] agree[s] that [their][its] obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability
of the 2031 Notes or the Eleventh Supplemental Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the 2031 Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of any
Guarantor. Each Guarantor waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and
covenant that the Guarantee in this Section 3 shall not be discharged except by complete performance of the obligations contained
in the 2031 Notes, the Eleventh Supplemental Indenture and this Joinder.

 

If any Holder or the Trustee is required by any
court or otherwise to return to the Company, the Guarantor[s] or any custodian, trustee, liquidator or other similar official acting in
relation to either the Company or the Guarantor[s], any amount paid by either to the Trustee or such Holder, this 2031 Note Guarantee,
to the extent theretofore discharged, shall be reinstated in full force and effect.

 

Each
Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the
one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated
as provided in Section 5.02 of the Base Indenture or Section 3.01 of the Eleventh Supplemental Indenture for the purposes
of this 2031 Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations as provided in Section 5.02
of the Base Indenture or Section 3.01 of the Eleventh Supplemental Indenture, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantor for the purpose of this 2031 Note Guarantee. Each Guarantor shall have the right to
seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under
this 2031 Note Guarantee.

 

    B-2

     

    

 

4.             Limitation
on Guarantor Liability. Each Guarantor, and by its acceptance of 2031 Notes, each Holder, hereby confirms that it is the intention
of all such parties that the 2031 Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any 2031 Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantor[s] hereby
irrevocably agree that the obligations of any Guarantor will, after giving effect to such maximum amount and all other contingent and
fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive
contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under
this Article 8, result in the obligations of such Guarantor under its 2031 Note Guarantee not constituting a fraudulent transfer
or conveyance.

 

5.             Execution
and Delivery of 2031 Note Guarantee. To evidence its 2031 Note Guarantee, each Guarantor hereby agrees that a notation of such
2031 Note Guarantee substantially in the form included in Annex A to this Joinder shall be endorsed by an Officer of such Guarantor
and that this Joinder shall be executed on behalf of such Guarantor by its President or one of its Vice Presidents.

 

Each Guarantor hereby agrees that its 2031 Note
Guarantee shall remain in full force and effect notwithstanding any failure to endorse a notation of such 2031 Note Guarantee.

 

6.             Guarantors
May Consolidate, etc., on Certain Terms. Except as otherwise provided in Section 7 of this Joinder, no Guarantor
may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not
such Guarantor is the surviving Person) another Person whether or not affiliated with such Guarantor unless:

 

(a)          subject
to Section 7 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger (if other than a Guarantor or the Company) unconditionally assumes all the obligations of such Guarantor, pursuant
to a supplemental indenture in form and substance reasonably satisfactory to the Trustee or by operation of law, under the 2031 Notes,
the Eleventh Supplemental Indenture and this 2031 Note Guarantee on the terms set forth herein or therein; and

 

(b)          immediately
after giving effect to such transaction, no Default or Event of Default exists.

 

    B-3

     

    

 

In
case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by operation of law or by
supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of this 2031 Note Guarantee endorsed
upon the 2031 Notes and the due and punctual performance of all of the covenants and conditions of the Eleventh Supplemental Indenture
to be performed by each Guarantor, such successor Person shall succeed to and be substituted for such Guarantor with the same effect as
if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the 2031 Note Guarantees
to be endorsed upon all of the 2031 Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered
to the Trustee. All the 2031 Note Guarantees so issued shall in all respects have the same legal rank and benefit under the Eleventh Supplemental
Indenture as the 2031 Note Guarantees theretofore and thereafter issued in accordance with the terms of the Eleventh Supplemental Indenture
as though all of such 2031 Note Guarantees had been issued at the date of the execution hereof.

 

Except
as set forth in Articles 8 and 10 of the Base Indenture and Articles 5 and 6 of the Eleventh Supplemental Indenture, and notwithstanding
clauses (a) and (b) above in this Section 6, nothing contained in the Eleventh Supplemental Indenture or in any of the
2031 Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any
sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

 

7.             Releases.
A Guarantor will be released and relieved of its obligations under the 2031 Note Guarantee upon the occurrence of any of the events
set forth in this Section 7.

 

(i)            In
the event of a sale or other disposition of all of the assets of such Guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all of the Capital Stock of such Guarantor, in each case to a Person that is not (either before or after giving
effect to such transactions) a Subsidiary of the Company if, after giving effect to such transaction, neither the Person acquiring such
Capital Stock nor such Guarantor has outstanding or guarantees any Specified Indebtedness, then such Guarantor (in the event of a sale
or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation
acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will
be released and relieved of its obligations under its 2031 Note Guarantee.

 

(ii)           In
the event the Company designates such Guarantor to be an Unrestricted Subsidiary in accordance with the Eleventh Supplemental Indenture,
such Guarantor shall be released and relieved of its obligations under its 2031 Note Guarantee.

 

(iii)          In
the event such Guarantor shall cease (or simultaneously with the release of its Guarantee hereunder shall cease) to have outstanding or
guarantee any Specified Indebtedness, such Guarantor shall be released and relieved of its obligations under its 2031 Note Guarantee.

 

Upon
delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of the Eleventh Supplemental Indenture, or upon delivery
by the Company to the Trustee of an Officers’ Certificate to the effect that the applicable Guarantor has ceased (or simultaneously
with the release of its 2031 Note Guarantee hereunder shall cease) to have outstanding or guarantee any Specified Indebtedness or that
the applicable Guarantor has been designated as an Unrestricted Subsidiary in accordance with the provisions of the Eleventh Supplemental
Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations
under its 2031 Note Guarantee.

 

    B-4

     

    

 

Any
Guarantor not released from its obligations under its 2031 Note Guarantee shall remain liable for the full amount of principal of and
interest on the 2031 Notes and for the other obligations of any Guarantor under the Eleventh Supplemental Indenture as provided
in this Section 7.

 

8.             Governing
Law. THIS JOINDER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

 

9.             Counterparts.
The parties may sign any number of copies of this Joinder. Each signed copy will be an original, but all of them together represent the
same agreement.

 

10.           Effect
of Headings. The Section headings herein are for convenience only and will not affect the construction hereof.

 

11.           The
Trustee. The Trustee will not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this
Joinder or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guarantor and the Company.
