After the original issuance of such 2021 Notes or 2021 Note Guarantees to be issued, any separate request by the Company that the Trustee authenticate such 2021 Notes or 2021 Note Guarantees 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 2021 Notes and 2021 Note Guarantees.

None of the 2021 Notes or the 2021 Note Guarantees 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 2021 Notes or 2021 Note Guarantees a certificate of authentication executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any of the 2021 Notes or the 2021 Note Guarantees shall be conclusive evidence, and the only evidence, that such 2021 Notes or 2021 Note Guarantees have been duly authenticated and delivered hereunder.

Section 2.07. CUSIP Number. The Company in issuing the 2021 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 2021 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 2021 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 2021 Notes. The Company will be entitled, upon delivery of an Officer’s Certificate and an Opinion of Counsel to issue Additional 2021 Notes under this Supplemental Indenture which will have identical terms as the Initial 2021 Notes issued on the date hereof, other than with respect to the date of issuance and issue price. The Initial 2021 Notes issued on the date hereof and any Additional 2021 Notes issued will be treated as a single class for all purposes under this Supplemental Indenture. With respect to any Additional 2021 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:

-23-

(a) the aggregate principal amount of such Additional 2021 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 2021 Notes.

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.

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

The Guarantors agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the 2021 Notes or this Supplemental Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the 2021 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 this 2021 Note Guarantee shall not be discharged except by complete performance of the obligations contained in the 2021 Notes and this Supplemental Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this 2021 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 hereof for the purposes of this 2021 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 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this 2021 Note Guarantee. The Guarantors 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 the 2021 Note Guarantee.

-34-

Section 8.02. Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of 2021 Notes, each Holder, hereby confirms that it is the intention of all such parties that the 2021 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 2021 Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors 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 2021 Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 8.03. Execution and Delivery of 2021 Note Guarantee. To evidence its 2021 Note Guarantee set forth in Section 8.01, each Guarantor hereby agrees that a notation of such 2021 Note Guarantee substantially in the form included in Exhibit B shall be endorsed by an Officer of such Guarantor on each 2021 Note authenticated and delivered by the Trustee and that this Supplemental Indenture shall be executed on behalf of such Guarantor by its President or one of its Vice Presidents.

Each Guarantor hereby agrees that its 2021 Note Guarantee as set forth in Section 8.01 shall remain in full force and effect notwithstanding any failure to endorse on each 2021 Note a notation of such 2021 Note Guarantee.

If an Officer whose signature is on this Supplemental Indenture or on the 2021 Note Guarantee no longer holds that office at the time the Trustee authenticates the 2021 Note on which a 2021 Note Guarantee is endorsed, the 2021 Note Guarantee shall be valid nevertheless.

The delivery of any 2021 Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the 2021 Note Guarantee set forth in this Supplemental Indenture on behalf of the Guarantors.

In the event that the Company creates or acquires any new Subsidiaries subsequent to the date of this Supplemental Indenture, the Company shall cause such Subsidiaries to execute a joinder to this Supplemental Indenture in substantially the form of Exhibit C hereto and 2021 Note Guarantees in accordance with this Article 8, to the extent applicable.

Section 8.04. Guarantors May Consolidate, etc., on Certain Terms. Except as otherwise provided in Section 8.05, 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 8.05 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

-35-

Trustee or by operation of law, under the 2021 Notes, this Supplemental Indenture and the 2021 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 the 2021 Note Guarantee endorsed upon the 2021 Notes and the due and punctual performance of all of the covenants and conditions of this Supplemental Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the 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 2021 Note Guarantees to be endorsed upon all of the 2021 Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the 2021 Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Supplemental Indenture as the 2021 Note Guarantees theretofore and thereafter issued in accordance with the terms of this Supplemental Indenture as though all of such 2021 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 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Supplemental Indenture or in any of the 2021 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.

Section 8.05. Releases.

A Guarantor will be released and relieved of its obligations under the 2021 Note Guarantee upon the occurrence of any of the events set forth in this Section 8.05.

(a) 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 2021 Note Guarantee.

(b) In the event the Company designates such Guarantor to be an Unrestricted Subsidiary in accordance with this Supplemental Indenture, such Guarantor shall be released and relieved of its obligations under its 2021 Note Guarantee.

-36-

(c) 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 2021 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 this 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 2021 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 this Supplemental Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its 2021 Note Guarantee.

Any Guarantor not released from its obligations under its 2021 Note Guarantee shall remain liable for the full amount of principal of and interest on the 2021 Notes and for the other obligations of any Guarantor under this Supplemental Indenture as provided in this Article.

3.500% Senior Notes due 2021

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 2021 Note at 3.500% per annum from the date hereof until maturity. The Company will pay interest semi-annually on May 15 and November 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 2021 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 2021 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 May 15, 2012. 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 2021 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 2021 Notes (except defaulted interest) to the Persons who are registered Holders of 2021 Notes at the close of business on the May 1 or November 1 next preceding the Interest Payment Date, even if such 2021 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 2021 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 2021 Notes at their respective addresses set forth in the register of Holders of 2021 Notes; provided that all payments of principal, premium and interest with respect to 2021 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 2021 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

A-3

Indenture”), dated as of November 19, 2009, between the Company and the Trustee, as supplemented and amended by the Second Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of November 14, 2011, among the Company, the Guarantors and the Trustee. The terms of the 2021 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 2021 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 2021 Note conflicts with the express provisions of the Indenture, the provisions of this 2021 Note will govern and be controlling. The Company will be entitled to issue Additional 2021 Notes pursuant to Section 2.08 of the Supplemental Indenture.

5. OPTIONAL REDEMPTION. (a) Except as set forth in Paragraph 5(b) hereof, the Company shall have the option to redeem the 2021 Notes, in whole or in part at any time and from time to time prior to August 15, 2021, at a Redemption Price (expressed as percentage of principal amount) equal to the greater of:

(i) 100% of the principal amount thereof; or

in each case 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 2021 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. Except as set forth in Paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the 2021 Notes.

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 2021 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 2021 Notes (the

A-4

“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 2021 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 2021 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. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder whose 2021 Notes are to be redeemed at its registered address. 2021 Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the 2021 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 2021 Notes or portions thereof called for redemption.

9. DENOMINATIONS, TRANSFER, EXCHANGE. The 2021 Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 2021 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 2021 Note or portion of a 2021 Note selected for redemption, except for the unredeemed portion of any 2021 Note being redeemed in part. Also, the Company need not exchange or register the transfer of any 2021 Notes for a period of 15 days before a selection of 2021 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 2021 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, the 2021 Note Guarantees or the 2021 Notes may be amended or supplemented with the consent of the Holders of not less than a majority in principal amount of the 2021 Notes (including Additional 2021 Notes under the Supplemental Indenture, if any). The Holders of not less than a majority in principal amount of the 2021 Notes (including Additional 2021 Notes, if any) may waive any past default with respect to the 2021 Notes and its consequences, except a default not theretofore cured in the payment of principal, premium, if any, or interest, if any, on the 2021 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 2021 Note.

A-5

(b) Without the consent of any Holder of a 2021 Note, the Supplemental Indenture, the 2021 Note Guarantees or the 2021 Notes may be amended or supplemented:

(i) to evidence the succession of another corporation to the Company or any Guarantor, or successive successions, and the assumption by any such successor of the covenants, agreements and obligations of the Company and such Guarantor pursuant to Article 6 and Section 8.04 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 2021 Notes as the Company and the Trustee shall consider to be for the protection of the Holders of the 2021 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 2021 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 to in Section 316(a)(2) of the TIA as in effect at the date as of which this instrument is executed or any corresponding provision in any similar federal statute hereafter enacted; or

(v) to add guarantors or co-obligors with respect to the 2021 Notes; or

Holders may not enforce the Supplemental Indenture or the 2021 Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the 2021 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the 2021 Notes notice of any continuing Default or

A-8

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 2021 Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the 2021 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 2021 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 or any Guarantor, as such, shall not have any liability for any obligations of the Company or the Guarantors under the 2021 Notes, the 2021 Note Guarantees 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 2021 Notes by accepting a 2021 Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the 2021 Notes.
