Effective as of the Reorganization Effective Time, each of Viatris Inc. and Acquisition Sub hereby fully and unconditionally Guarantee the obligations of Mylan Inc. in respect of the Notes on the terms set forth herein, in the Guarantee and in the Indenture including, but not limited to, Sections 2, 3, 4 and 5 of the Second Supplemental Indenture.

4. TERMS OF GUARANTEES. Sections 2, 3, 4 and 5 of the Second Supplemental Indenture are hereby deleted in their entirety and replaced with the following:

“2. Agreement to Guarantee. Each Guarantor hereby agrees as follows:

(a) Each Guarantor hereby jointly and severally, absolutely, unconditionally, fully and irrevocably guarantees the Notes and obligations of Mylan Inc. thereunder and under the Indenture, and guarantees to each Holder of a Note authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, that (i) the principal of (and premium, if any) and interest on the Notes will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including, without limitation, the amount that would become due but for the operation of any automatic stay provision of any federal bankruptcy law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of Mylan Inc. to the Holders or the Trustee under the Indenture or the Notes will be paid in full or performed, all in accordance with the terms of the Indenture and the Notes; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

(b) Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture or the absence of any action to enforce the same, any waiver or consent by any Holder of Notes with respect to any provisions of the Indenture or the Notes (other than those which expressly release, discharge or otherwise affect the Guarantee of such Guarantor), any release of any other Guarantor, the recovery of any judgment against Mylan Inc., any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(c) Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of Mylan Inc., any right to require a proceeding first against Mylan Inc. or any other Person, protest, notice and all demands whatsoever and covenants, subject to Section 6 hereof, that the Guarantee of such Guarantor shall not be discharged as to the Notes, except by complete performance of the obligations contained in the Notes, the Indenture and such Guarantee. Each Guarantor acknowledges that the Guarantee is a guarantee of payment and not of collection.

(d) Each of the Guarantors hereby agrees that, in the event of a default in payment of principal (or premium, if any) or interest on any Notes, whether at Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Notes, subject to the terms and conditions set forth in the Indenture, directly against each of the Guarantors to enforce such Guarantor’s Guarantee without first proceeding against Mylan Inc. or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the Maturity of the Notes, to collect Interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

(e) If any Holder or the Trustee is required by any court or otherwise to return to Mylan Inc. or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either Mylan Inc. or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand (x) subject to the terms and provisions of this Supplemental Indenture, the Maturity of the obligations guaranteed hereby may be accelerated as provided in Article VII of the Indenture for the purposes of the Guarantee of such Guarantor notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VII of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purpose of the Guarantee of such Guarantor.

(f) Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against Mylan Inc. for liquidation or reorganization, should Mylan Inc. become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of Mylan Inc.’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(g) For purposes of this Section 2, Section 3 and Section 4, the definition of “Guarantee” and “Guarantor” in the Indenture is hereby deleted in its entirety and replaced with the following:

“Guarantee” means the guarantee by a Guarantor of the Notes and obligations of Mylan Inc. thereunder and under the Indenture.

“Guarantor” means any direct or indirect parent entity or subsidiary of Mylan Inc. that guarantees the Notes and obligations of Mylan Inc. thereunder and under the Indenture.

3. Reinstatement. Each Guarantor hereby agrees that its Guarantee provided hereunder shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to Mylan Inc. upon the bankruptcy or insolvency of Mylan Inc. or any other Guarantor.

4. Contribution; Subrogation. In order to provide for just and equitable contribution among the Guarantors, in the event any payment or distribution is made by any Guarantor under a Guarantee, such Guarantor will be entitled to a contribution from any other Guarantor in a pro rata amount based on the net assets of each Guarantor determined in accordance with GAAP. Each Guarantor shall be subrogated to all rights of Holders against Mylan Inc. in respect of any amounts paid by any Guarantor pursuant to its Guarantee; provided, however, that if an Event of Default has occurred and is continuing, the applicable Guarantor shall not be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by Mylan Inc. under the Indenture or the Notes shall have been paid in full.

5. Execution and Delivery. Each Guarantor hereby agrees that its Guarantee will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.”

5. CONSOLIDATION, MERGER AND SALE OF ASSETS OF VIATRIS INC.

(a) Viatris Inc. will not consolidate with any other entity or accept a merger of any other entity into Viatris Inc. or permit Viatris Inc. to be merged into another Person, or sell or lease all or substantially all the assets of Viatris Inc. and its Subsidiaries to, any entity, unless:

(1) either Viatris Inc. shall be the continuing entity or the successor, transferee or lessee entity, if other than Viatris Inc. (the “Viatris Inc. Successor Company”) shall expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of Viatris Inc. under the Viatris Guarantee;

(2) immediately after such transaction, no Default shall have occurred and be continuing; and

(3) Viatris Inc. shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale or lease and such supplemental indenture (if any) comply herewith.

(b) For purposes of this Section, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets or one or more Subsidiaries of Viatris Inc., which properties and assets, if held by Viatris Inc. instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of Viatris Inc. on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of Viatris Inc.

(c) The Viatris Inc. Successor Company will be the successor to Viatris Inc. and shall succeed to, and be substituted for, and may exercise every right and power of, Viatris Inc. under the Viatris Guarantee, and Viatris Inc., as the predecessor company, except in the case of a lease, shall be released from all obligations under the Viatris Guarantee.

6. NO RECOURSE AGAINST OTHERS. No director, officer, employee or stockholder of Mylan Inc. or any of the Note Guarantors will have any liability for any of Mylan Inc.’s or such Note Guarantor’s obligations under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Note Guarantees.

7. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK (INCLUDING, WITHOUT LIMITATION, SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW OR ANY SUCCESSOR TO SUCH STATUTE) WILL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

8. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture by manual, facsimile or electronic signature. Each signed copy shall be an original, but all of them together represent the same agreement. Signatures of the parties hereto transmitted by facsimile or electronic format (i.e., “pdf” or “tif”) shall be deemed to be their original signatures for all purposes.

9. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.

10. THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by Mylan Inc. and the Note Guarantors. In entering into this Supplemental Indenture, the Trustee shall be entitled to the benefit of every provision of the Indenture relating to the conduct of or affecting the liability of or affording protection to the Trustee.

11. RATIFICATION OF THE INDENTURE; SUPPLEMENTAL INDENTURE PART OF THE INDENTURE. Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof, including, without limitation, Section 11.01 thereof, shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of the Notes shall be bound hereby.

12. APPOINTMENT OF AGENT FOR SERVICE.
