RE:	Integration Planning Steering Committee Formed; Planning for First Day as Combined Company Begins

Approximately two weeks ago, we announced our intention to combine our two great companies into a single organization. The reaction to this announcement, particularly throughout the investment community, was widely and overwhelmingly positive.

For example, Gregg Gilbert, an analyst with BofA/Merrill Lynch, noted, “… we have long been fans of the concept of a Specialty Pharma business model that has diversity of business mix (brands/generics/biosimilars) and geography, a thoughtful and targeted R&D strategy, and the potential for additional business development. Therefore, this combination… is appealing to us.” Jami Rubin, with Goldman Sachs, wrote, “Blurring the distinction between specialty/generics and large cap pharma, we see ACT transforming … with an equal balance of brands and generics.” ¹

Integration Planning Begins

As we noted at the announcement, we anticipate that the proposed combination of Actavis and Forest will be completed, subject to regulatory clearance, around mid-year. That gives our two teams just four months to plan for integration, and to ensure that we operate seamlessly, as a single company, on Day 1 while achieving each company’s individual goals between now and closing. Now, the hard work of preparing to realize the potential of this combination begins.

Today, we are pleased to announce the Integration Leadership Group that will begin to organize the many work streams that will lead to the integration. This Integration Leadership Group, which held its initial meeting on February 27^th, has two key objectives. The first is to ensure that our two companies, operating independently until close, meet all of the separate business objectives that we have each established prior to the announcement. The second objective is to meticulously plan for the combination, ensuring that we capture all of the energy, skills and talent of both organizations, and unite the teams at closing in a way that delivers immediate and long-term growth for the combined business.

Office of the Chairman

A key challenge of combining the two successful organizations is harnessing the leadership talents of both companies to drive the success of the combined organization. To focus on this initiative, we have established the new Office of the Chairman. Led by Paul Bisaro, and including Brent Saunders of Forest and Siggi Olafsson of Actavis, we will ensure that integration planning activities do not interfere with the independent operation of Actavis and Forest, while working together to establish the leadership structure that will manage the combined business, post close.

Paul, Brent and Siggi will work cooperatively to select the combined company’s leadership from the “all-star team” of exceptionally experienced and talented executives within each company.

Integration Leadership Group

In addition to establishing the Office of the Chairman, we have also defined the team leaders that will jointly direct integration planning initiatives. Both Actavis and Forest management teams are equally represented in this task force.

Each of these teams will focus on their respective business functions, to ensure that we are prepared to combine the business at closing with minimal to no interruption for our customers, and to ensure value creation for all of the shareholders and employees in the combined company.

Rx North America

Until close, we must focus on continuing to drive sales of our individual product portfolios, and meet the separate product sales and earnings commitments of our companies. Each company must operate separately during this period, so no operational changes will be made before closing. However, the Integration teams will consider how, after closing, to best structure brand sales, marketing and other activities that will be responsible for the success of the combined, larger and more complex portfolio on Day 1.

It is important to note that our commercial sales teams — the Actavis North American generics and International commercial business teams, and the Forest U.S. commercial teams — remain focused on meeting their 2014 commitments in terms of product launches and sales. Members of these organizations will also provide support as needed throughout the integration planning process.

R&D

For our R&D team, the focus will be on preparing to combine the brand pharmaceutical development and commercialization activities as effectively as possible, after closing. This will focus on prioritization of our combined world class R&D portfolio and working to maximize the value of both internally developed and partnership created projects. Other teams within the group will consider how to best structure the organization and allocation of resources at close among the combined organization that will support such other R&D related functions as pharmacovigilance, medical affairs and regulatory affairs.

The Actavis global generics research team will remain focused on their industry-leading product development and filing activities throughout the integration process, as will the biosimilars team, while supporting the brand R&D integration planning and resource allocation as appropriate throughout this process.

Global Operations

Our Operations team will not only look at the expanded global network following the close, which will include Forest manufacturing and distribution capabilities, but also at quality, procurement, purchasing, information technology and other areas within the global supply chain organization.

Corporate Development

The Corporate Development teams of Actavis and Forest, during the transition, will continue to separately and independently pursue already established business development initiatives. They will also be establishing a business development structure to lead this critical function, and begin defining priorities that the combined company may elect to pursue following close.

Finance

Members of the Finance teams from both organizations will be exploring how to best combine the separate practices and functions that will support the combined organization, both on a reporting as well as operational basis. They will be exploring the most effective ways to support the larger company in such areas as budgeting and forecasting, accounting, treasury, insurance, tax accounting and accounting operations.

Legal

While our legal teams will be working to support the successful completion of the transaction, as well as the continued operation of compliant organizations throughout the transition period to close, this combined integration team will also be defining how to best structure the legal organization to support the more complex global business in such areas as commercial legal, intellectual property, compliance and internal audit functions.

HR

Members of the HR teams from both organizations will be tasked with reviewing all employee oriented policies, procedures and business practices, to ensure the harmonization of the practices that will support the more than 24,000 people of the combined company on Day 1.

Corporate Communications

The Corporate Communications teams of both organizations will be working together during the transition to educate employees about the combined strengths and capabilities of the combination, as well as communicating milestones in the integration planning process. The teams will also cooperate in ensuring that investors and shareholders understand the value of the combination in support of approval of the shareholders of both companies. Finally, this team will plan how to best present the capabilities of the combined business as a new model in specialty pharmaceuticals at close and beyond.

Integration Planning Teams

As the Integration Leadership Group defines work streams and establishes aggressive objectives for close, members of the Actavis and Forest organizations may be asked to assist in integration planning activities, and in supporting various committees and work streams. The various integration teams will work toward defining Day 1 deliverables, including addressing planning for business continuity, following the close of the transaction. We thank all employees who will be involved in this integration initiative in advance for accepting the challenge of supporting the integration.

Operating Separately Until Close

It is important to remember that until close, Actavis and Forest will continue to operate as separate companies, and competitors, focused on continuing to grow our respective businesses and deliver the financial results we have promised to our shareholders; continuing to deliver the highest quality products, with the best service to our customers; and continuing to focus on improving all that we do.

We are committed to sharing achievements and milestones in the integration planning throughout this process. More information will be available on myActavis, OurWinningWay.com, and the Forest intranet.
