Associates of American Retirement Corporation
Bill Sheriff, Chairman, President and CEO
Acquisition of American Retirement Corporation by Brookdale
As you may already be aware, a press release was issued today announcing Brookdale’s transaction with American Retirement Corporation (NYSE:ACR). I want to share with all of you some additional information about the transaction and why this is not only a historic event, but also a very exciting opportunity for all associates of both companies.
  The combination of American Retirement Corporation (“ARC”) and Brookdale Senior Living Inc. will create the largest operator of senior living facilities in the United States. Based on our collective current operations (not including future acquisitions), after the transaction we will operate 536 facilities with over 50,000 units/beds. Approval for the transaction is subject to the approval of ARC shareholders and other customary closing conditions, but we expect the transaction to close later this year.
  Leadership for the combined company will be Mark Schulte (currently CEO of Brookdale) and Bill Sheriff as Co-CEO’s with John Rijos and Mark Ohlendorf as Co-Presidents (currently the Co-Presidents of Brookdale). All three operating groups in Chicago, Milwaukee and Nashville will remain in place. Key to our on-going success will be bringing together two of the industry’s leading operating cultures and creating a very powerful combined operating platform. In this regard, we are committed to work very hard to retain and promote talent across the entire organization as we proceed with the integration of both companies. I am also pleased to announce that all of the Senior Executives from ARC have committed to join the combined company.
  To coordinate the integration process we will pursue a joint effort involving personnel from both organizations. We expect to commence this process in the near future.
Established in 1978, ARC has a long history as a premium provider in the senior living industry. ARC and Brookdale are very similar in many respects: we both have very strong resident focused missions and operations; we both have product offerings spanning the entire senior living spectrum, from independent living through skilled nursing; we both have strong, talented people with long tenure at every level of the company; and we have both built and acquired some of the highest quality senior living properties in the U.S. Most importantly, both companies enjoy strong reputations in the



industry and with our customers based on high-quality operations, integrity and innovation. Throughout this transaction, we will be looking to build on and strengthen all of these areas.
The addition of ARC to Brookdale solidifies the combined company’s leadership position in the industry with the following benefits:
  The combined company will not only be dominant in senior living, but in every business line that we operate: CCRC, independent living, assisted living, memory care and skilled nursing. The combination of experience and talent of ARC and Brookdale will create a very powerful organization.
  Both ARC and Brookdale operate in many of the same markets, creating many opportunities for geographic and market synergies.
  Each company brings core competencies and strengths that will benefit the other. ARC has built a very solid ancillary service and therapy business that can be implemented across Brookdale’s properties. ARC has built a very solid infrastructure for the ancillary services business that will greatly enhance the revenue and product offerings of Brookdale’s existing properties. Implementation of some of Brookdale’s service and support programs will benefit ARC’s communities and residents.
  The scale of the combined company will allow us to provide more and better resources to service the field such as training, policies and procedures, IT resources, etc.
  Our purchasing power will be greatly enhanced across the bandwidth of corporate purchasing targets such as insurance, telecommunications, utilities and food, just to name a few.
As we all know, the integration process will be ongoing for some time after the transaction closes. As more plans and details become available, we will share those with you. I hope you share my excitement and enthusiasm for this very significant milestone for ARC, Brookdale and the industry.
Thanks to all of you for your hard work. Combining the talents and commitment of our two organizations, we can build an industry-leading, world-class company with a very bright future.
