On August 1, 2013, Actavis, Inc. (f/k/a Watson Pharmaceuticals, Inc., the “Company”), Bank of America, N.A. and a syndicate of banks participating as lenders entered into (i) an amendment agreement (the “Revolver Amendment”) to amend and restate the Company’s existing $750 million senior unsecured revolving credit loan facility dated as of September 16, 2011, as amended by that certain Amendment No. 1 to Credit Agreement and Joinder Agreement, dated as of May 21, 2012 (such facility, prior to its amendment and restatement pursuant to the Revolver Amendment, the “Existing Revolver”) and (ii) an amendment agreement (the “Term Loan Amendment”) to amend and restate the Company’s existing $1.8 billion senior unsecured term loan credit facility dated June 22, 2012 (such facility, prior to its amendment and restatement pursuant to the Term Loan Amendment, the “Existing Term Loan”). The Revolver Amendment and the Term Loan Amendment are referred to collectively herein as the “Amendments”. The Existing Revolver and the Existing Term Loan are referred to collectively herein as the “Existing Credit Facilities”. The Amendments became effective in accordance with their terms on August 1, 2013.

The Amendments will, among other things described below or more fully set forth in the Amended and Restated Credit Facilities (as defined below): (i) replace the Company, as borrower, with a newly-formed Luxembourg company, Actavis WC Holding S.à r.l. (the “ACT Borrower”) that will be a direct or indirect parent of the Company and a direct or indirect wholly-owned subsidiary of Actavis Limited which, prior to the Closing Date (as defined below) will be converted into a public limited company and renamed Actavis plc (“Parent”),(ii) add Parent and the Company as guarantors, (iii) delete the springing minimum net worth financial maintenance covenant and (iv) revise certain representations and warranties, financial reporting requirements and other affirmative and negative covenants and events of default as set forth in the Amended and Restated Credit Facilities. In addition, the Revolver Amendment will extend the maturity of the Existing Revolver by one year, to September 16, 2017 (or if such day is not a business day, the next preceding business day). The Existing Revolver and the Existing Term Loan, as amended by the Amendments, are referred to herein respectively as the “Amended and Restated Revolver” and the “Amended and Restated Term Loan” and, collectively, the “Amended and Restated Credit Facilities”. The date of the consummation of the Company’s proposed acquisition (the “Acquisition”) of Warner Chilcott plc (“Warner Chilcott”) (as described in the Company’s Current Report on Form 8-K dated May 19, 2013) is referred to herein as the “Closing Date”.

Interest Rate and Amortization

The Amended and Restated Term Loan provides that loans thereunder will bear interest, at the ACT Borrower’s choice, of a per annum rate equal to either (a) a base rate, plus an applicable margin per annum varying from 0.00% per annum to 1.00% per annum depending on the publicly announced debt ratings for non-credit-enhanced, senior unsecured long-term indebtedness of Parent (such applicable debt rating the “Debt Rating”) or (b) a Eurodollar rate, plus an applicable margin varying from 1.00% per annum to 2.00% per annum depending on the Debt Rating.

The Amended and Restated Revolver provides that loans thereunder will bear interest, at the ACT Borrower’s choice, of a per annum rate equal to either (a) a base rate, plus an applicable margin per annum varying from 0.00% per annum to 0.75% per annum depending on the Debt Rating or (b) a Eurodollar rate, plus an applicable margin varying from 0.875% per annum to 1.75% per annum depending on the Debt Rating.

The Amended and Restated Term Loan will mature on October 31, 2017 (or if such day is not a business day, the next preceding business day), and the outstanding principal amount is payable in equal quarterly installments of 2.50% per quarter, with the remaining balance payable on the maturity date. The Amended and Restated Revolver will now mature on September 16, 2017 (or if such day is not a business day, the next preceding business day).

Guarantees

The Amended and Restated Credit Facilities will provide that all obligations thereunder will be jointly and severally guaranteed by (i) Parent, (ii) the Company and (iii) any subsidiary (other than the ACT Borrower) that becomes a guarantor of third party indebtedness of the ACT Borrower in an aggregate principal amount exceeding $200,000,000 (unless, in the case of a foreign subsidiary, such guarantee would give rise to adverse tax consequences as reasonably determined by Parent).

Representations, Covenants and Events of Default

The Amended and Restated Credit Facilities will contain customary representations and warranties, financial reporting covenants and other affirmative and negative covenants and events of default (the occurrence of which may trigger an acceleration of amounts outstanding under the Amended and Restated Credit Facilities).

In addition, Parent shall be required to comply with a quarterly total leverage maintenance covenant that is substantially similar to the covenant in the Existing Credit Facilities.
