November 2006

Dear Employee:

As you may have heard, Caremark (the company that provides your prescription benefit services on behalf of [CLIENT NAME]) recently announced plans to merge with CVS Corporation, the nation’s largest pharmacy chain. By joining together, the two companies will become the premier integrated pharmacy services provider in the U.S.

The merger will not be completed for another 6-12 months, so you will see no changes for some time. Over time, the new company will be able to provide you with a whole new level of convenience, value and service. The company will also be better positioned to help you manage the costs and complexities of the healthcare system and drive superior healthcare outcomes.

Once the merger is completed, you will continue to have access to all the services available to you now. You will have enhanced personal interaction with pharmacists through the phone and in-person at CVS stores, making it easier for you to adhere to your prescription requirements and get information about your healthcare choices. The combined CVS/Caremark will be able to do even more to help you maximize benefits you receive under our current plan. The new company also intends to continue providing access to the large, nationwide network of participating pharmacies currently available to you. And of course, you will still have access 24 hours a day, 7 days a week through the Caremark toll-free number to pharmacists and service specialists.

We understand that you may have questions about how Caremark and CVS coming together may affect your benefits. We have enclosed a set of the most Frequently Asked Questions and provided the answers. We hope you find this information helpful.

 


In the meantime, if you have questions regarding your prescription coverage, please call toll-free at the phone number on your prescription benefit card. You may also access the Caremark Web site at www.caremark.com. Use Caremark.com to order your long-term prescription refills, check your medicine coverage and cost, and more. For those plan participants requiring telecommunications device (TDD) assistance, please dial toll-free 1-[XXX-XXX-XXXX].
