Pre-Integration Planning Meetings Begin;

Proposed Senior Leadership of Combined Company Announced

On Monday, December 15th, we began the process of planning the integration that will bring Actavis and Allergan together next year, if the transaction closes successfully as anticipated. More than 100 people, from both companies, joined us for the kick-off of the Pre-Integration Planning Meeting in Parsippany, New Jersey, USA, where we will review the principles that will drive decision-making during integration; reiterate our commitment to operating in a business-as-usual mode as two separate companies until close; and begin the dialogue that will permit us to plan for a seamless transition to one global company.

In addition, we took the opportunity of the Pre-Integration Planning Kick-off Meeting to announce the proposed senior leadership team that will lead our new company once the transaction is complete.

One of the guiding principles of Pre-Integration Planning is our commitment to frequent, transparent and specific communications through the process. The proposed senior leadership structure that we are announcing today is the result of extensive discussions with members of the management teams of both Actavis and Allergan. It demonstrates our commitment to capitalize on our expanded global commercial footprint, ensure our



continued dominance as a world leader in generics, and to recognize the strengths of both of our businesses and the proven track record of the leaders of these powerful and successful companies.

We said that the new, combined company would reflect the “best-of-the-best” of both companies. The proposed leadership structure we are announcing today, and subsequent cascading announcements of next levels leadership, will prove that we intend to deliver on that promise. We are making this announcement today to provide employees of both organizations with more visibility into how we intend to operate beginning on Day 1. We will continue to define and announce, as rapidly as possible, subsequent levels of management. We encourage all employees to refrain from speculating about what these announcements mean for departments, functions and individuals, until clarity around organizational structure is communicated. It is critical for us all to remember that the proposed combined management structure will not take effect until close. Current Allergan and Actavis leadership and all team members must continue to focus on operating as independent companies prior to close, which we anticipate in the second quarter of 2015.

Proposed Senior Leadership Structure

Our goal in creating this proposed management team has many objectives. We want to ensure that we are structured to deliver on our promise to shareholders to build a new paradigm as the Growth Pharma Company based on an unrivaled foundation for long-term growth, including the potential for double-digit organic revenue and earnings growth, anchored by leading, world-class blockbuster franchises and a premier late-stage pipeline. We also want to ensure that we remove concern about how teams and functions will operate in the future. We also want, as much as possible, to answer questions about organizational structure and management as rapidly as possible, with the understanding that we are announcing decisions as they are made, and this is a work in progress.

Below is the proposed top line management for the combined company at close, as well as additional detail on functional management within key functions. Over the next days and weeks, we will continue to build out the cascading layers of leadership. We ask for your patience as we understand this announcement will not answer all employee questions.



We want to take you through key functions within the organization, particularly in those areas that represent the most significant changes to existing organizational structures within both Actavis and Allergan.

We are pleased to announce that Doug Ingram, President of Allergan, will serve as a special advisor to Brent following the close of the transaction. In this position, the combined company will continue to benefit from Doug’s extensive experience and expertise, as we seek to accelerate growth across the combined company. We are excited that Doug will continue to contribute to the success of the company, and provide valuable counsel on how to best ensure we capitalize on the strengths of Allergan’s portfolio and exceptional marketplace strengths in the new company.





Commercial Organization

Our combined company will have commercial operations in more than 100 countries, and a more complex combined portfolio of brand products. In addition to ensuring that we retain the intellectual firepower that has driven Actavis’ and Allergan’s commercial success, we also want to ensure that we retain laser-like focus on continuing to drive growth in our industry-leading global generics business. As a result, in both the highest level of management, to the commercial market and portfolio level, we are committed to a management structure that ensures we remain responsive to customer needs across brands, generics, branded generics and Over-the-Counter (OTC) products.

Brand Commercial Leadership

To support continued momentum across the broader, brand product portfolio, our global brand sales and marketing will be structured into three organizations following the close of the acquisition: International Brands, Branded Pharma and Allergan Medical.


    Paul Navarre, Allergan Corporate Vice President and President, Europe, Africa and the Middle East, will become Executive Vice President, Actavis and President, International Brands. Medical aesthetics and devices will continue to report to International Brands outside of the U.S.


    Bill Meury, Actavis Executive Vice President for North American Brands will become Executive Vice President, Actavis and President, Branded Pharma with responsibility for Eye Care including Retina, Neurosciences, CNS, Gastroenterology, Women’s Health, Urology and other Specialty brand products. Allergan’s Pacific Communications function, which specializes in new technology, marketing development, product launch and marketing communications, will be aligned under the Business Analytics and Operations function within Bill’s team.


    Philippe Schaison, Allergan Corporate Vice President, President Allergan Medical, will become Executive Vice President Actavis, President Allergan Medical, which will include Facial Aesthetics, Medical Dermatology, Plastic Surgery and SkinMedica.

As you can see from the organizational chart, we are focused on recognizing exceptional talent across both organizations to drive continued growth across key markets and therapeutic categories. This structure is balanced across Actavis (including legacy Actavis and legacy Forest) as well as Allergan leaders.



Brand R&D to Report to Mr. Saunders

The combined company will have an investment of more than $1 billion in brand product development. Because of the importance of continually expanding our global product portfolio, we have determined that this function should report directly to the CEO and President. Actavis’ C. David Nicholson, PhD, Senior Vice President, Global Brands R&D, will lead this function after close as Executive Vice President Brand R&D. We will look to David’s leadership to capitalize on Allergan’s R&D expertise by retaining its industry-leading talent, and combine it with the expertise of his Actavis team, to maintain development momentum across the expanded Actavis and Allergan combined portfolio.

Together, we will maintain a focus on strategic development of innovative and durable value-enhancing brand products and will have more than two dozen mid- and near-term products in development. We anticipate being able to announce additional team members within this organization over the next several weeks. But we want to reiterate that we are focused on retaining Allergan’s research and development expertise in its therapeutic categories, which is additive to Actavis, and maintaining R&D activities at Allergan’s Irvine, California facility.

Generics and Global Operations

To ensure our combined company maintains focus on its global generics business, Bob Stewart will become Executive Vice President, Actavis and President, Generics and Global Operations, reporting to Brent. Aligning generic sales and marketing, generic R&D, and global operations — including Actavis and Allergan manufacturing, supply chain and quality — and shared service optimization within one organization will enable us to capitalize on the interdependency of all phases of the generic business: from product identification, development and approval, to manufacturing and finally global commercialization.



Within the global commercial structure, our current generics commercial leadership will now be incorporated into Bob’s organization. We will become even more nimble and responsive in our ability to meet changing customer needs and our ability to maximize market opportunities. David Buchen, currently Executive Vice President North American Generics and International will continue in his current responsibilities until close, when he will assume new responsibilities on special projects in support of Brent and Paul Bisaro, Actavis Executive Chairman.

Global Functions

To support the combined company, we are also announcing the leadership of global functions, all of whom report to Brent following the close.


    Tessa Hilado, EVP, Chief Financial Officer, who will also assume responsibility for leading Information Technology (IT)


    Robert Bailey, EVP, Chief Legal Officer and Corporate Secretary


    Karen Ling, EVP, Chief Human Resources Officer


    Charlie Mayr, EVP, Chief Communications Officer


    Sigurd Kirk, EVP, Corporate Business Development


    Jonathon Kellerman, EVP, Global Chief Compliance Officer

In preparation for the combination of our two companies, Alex Kelly, Actavis Senior Vice President and Chief Integration Officer; and Sanjiv Patel, Allergan Corporate Vice President, Global Strategic Marketing & Global Health Outcomes Strategy and Research, will share jointly in the responsibility for Pre-integration Planning. Sanjiv will also continue his current role leading the Allergan Global Strategic Marketing & Global Health Outcomes Research and Strategy organization reporting to Mr Saunders. As Pre-Integration Planning continues, we will work on how to best align the capabilities of these groups in the larger organization to provide a vital linkage between the combined company’s global brand product development and commercialization activities to optimize its impact. Communications about final decisions on this strategy and structure will be communicated in the coming weeks.

We believe that by announcing the proposed structure of the combined organization our employee teams, shareholders and customers will better appreciate our commitment to creating the most dynamic company in growth pharma and will share our confidence in seamless execution of this combination beginning on Day 1. While we have not answered all questions, we remain committed to announcing cascading organizational structures as those decisions are made.



Until closing, we must continue to operate as separate companies, focused on continuing to grow our respective businesses and deliver the financial results we have promised to our shareholders, while also meeting and exceeding the expectations of our customers to provide the highest quality products and services.

We want to thank all employees, in advance, for continuing to focus on driving success in our separate companies to ensure we have a strong foundation when we begin operating as one organization next year.
