 SECOND SUPPLEMENTAL INDENTURE 
 SECOND SUPPLEMENTAL
INDENTURE (this “Second Supplemental Indenture”), dated as of December 21, 2010, among Generics Bidco I, LLC (the “Guaranteeing Subsidiary”), a Delaware limited liability company and a subsidiary
of Endo Pharmaceuticals Holdings Inc. (or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and Wells Fargo Bank, National
Association, as trustee under the Indenture referred to below (the “Trustee”). 
 W I T N E S S E T H

 WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture, dated as of November 23, 2010,
as supplemented by a supplemental indenture on December 13, 2010 (as so supplemented, the “Indenture”), providing for the issuance of 7.00% Senior Notes due 2020 (the “Notes”); 

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a
supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note
Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and
deliver this Second Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to
them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary
hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof. 

4. NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator
or stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, this 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. The waiver may not be effective to waive liabilities
under the federal securities laws. 
 5. NEW YORK LAW TO GOVERN; WAIVER OF JURY TRIAL. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SECOND 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. THE COMPANY,
THE TRUSTEE, THE GUARANTEEING SUBSIDIARY AND 







 
EACH OF THE GUARANTORS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 6. COUNTERPARTS. The parties may sign any number
of copies of this Second Supplemental Indenture. Each signed copy (which may be provided via facsimile or other electronic transmission) shall be an original, but all of them together represent the same agreement. 

7. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not
affect the construction hereof. 
 8. THE TRUSTEE. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this Second Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary, the other
