FROM:	Bill Meury, EVP, Sales and Marketing, Forest
RE:	Proposed Senior Leadership for North American Brand Sales and Marketing

In preparing for the close of the acquisition, I am pleased to announce the management team for the North American Brands business. The organization has been designed to manage a broad, diverse, and growing portfolio consisting of over 30 marketed products in seven therapeutic areas as well as a steady stream of new products in the future. Our aim is to have a best-in-class organization that is innovative, customer focused, and skilled at launch planning and execution in both specialty and primary care markets. Each member of the management team is committed to working together and with you to meet the needs of our customers and maximize the value of our product lines.

Sales

All sales teams, including primary care, specialty, institutional, and managed care, have been consolidated into one group. This was done to enable a unified approach to our most valuable customers. It was also done to create the scale and flexibility required for primary care products, while at the same time, preserve the focus needed for specialty. Jerry Lynch will lead the new combined organization as well as the sales administration and analytics, sales operations, sales training, and account management teams. Jerry will share specifics about the design and leadership for the new organization in the weeks ahead.

Marketing

Five distinct marketing groups with strategic planning, tactical implementation, and P&L responsibilities have been created and will be led by skilled and experienced executives. Will Kane will have responsibility for the internal medicine group, which consists of our CNS, cardiovascular, and respiratory product lines. Chuck Sabino will manage the entire GI portfolio. Herm Cukier will manage our extensive women’s health product line. Steve Closter will manage our urology, dermatology, and established brands portfolios, and Cristina Larkin will lead our growing anti-infective business.

Business Analytics & Operations

Business Analytics and Marketing Operations will consist of market research, commercial assessments, digital and consumer marketing, and marketing services. This new group will have both strategic and operational responsibilities, including evaluating new product opportunities and promotional strategies as well as working with the marketing teams to implement leading edge promotional techniques. Tom Nee will lead this important area.

Pricing and Access

The Vice President of Pricing and Access, who will be named later, will be responsible for pricing and discount strategies, contract analysis, and segment marketing.

Canada

Rob Tessarolo will have responsibility for our brand marketing and sales activities in Canada. The combined company will add to its already extensive product line with multiple product launches in the next several years.

Tim Callahan, who has been an invaluable part of the Actavis management team, has elected to leave to pursue other opportunities. Tim will continue on a transitional basis through September. We thank him for his contributions to Actavis and wish him the best in his future endeavors.

These appointments will take effect following completion of the acquisition. Additional organizational announcements will be made in the future. While we are announcing this structure today to facilitate integration planning, all employees of both companies will continue in their present roles until the close.

Business as Usual

With these announcements, we are providing clarity as to the initial organization of what will be a much larger and more complex global company. We will share more specifics about the leadership for individual teams or divisions in the next several weeks.

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.
