Subject: BD Announces Agreement to Acquire CareFusion

Dear BD Associates:

I am very pleased to share with you an exciting milestone in BD’s history. Today, we announced an agreement to acquire CareFusion, a leading medical technology company with products and services that help hospitals measurably improve safety and patient care. This transaction will enable BD to become a global leader in the growing $20 billion medication management industry.

We’ve long admired CareFusion’s strong franchise and leading positions, and look forward to welcoming their talented team to the BD family. CareFusion, with about $4 billion in annual revenues, is based in San Diego, California, with 25 manufacturing facilities and nearly 17,000 employees. While most of CareFusion’s sales are in the U.S., it has a stable customer base of hospitals, ambulatory surgery centers, clinics, long-term care facilities and physician offices in approximately 130 countries. Some of CareFusion’s products that may be familiar to you include drug dispensing technologies (Pyxis^®), drug administration devices utilizing infusion pumps (Alaris^®), medication management informatics (CareFusion SmartWorks), as well as a broad portfolio for acute care including infection prevention (ChloraPrep^®).

Importantly, this combination will accelerate our strategy to transition from a product-focused company to a customer-centric provider of complete healthcare solutions across the medication management value chain. In addition, the Company will have solid positions in patient safety to maximize outcomes in infection prevention, respiratory care, and acute care procedural effectiveness. We think this will create value for our customers and shareholders and also open up exciting new opportunities for employees.

The transaction is expected to close in the first half of calendar year 2015 following regulatory and other required approvals. A comprehensive integration plan, designed by a team led by BD COO Bill Kozy and including senior members of both BD and CareFusion, will be communicated to both organizations at the appropriate time to help ensure a smooth and seamless transition. In the meantime, it is important to remember that we are just at the beginning of a long process. Until the transaction closes, it is business as usual, and both BD and CareFusion will continue to operate as separate companies. I ask that you remain focused on doing the jobs you do so well and on delivering the highest quality products and services our customers and partners have come to expect from us.

I know you will want to learn more about this announcement, so we will be hosting two town hall meetings. Details are below.

We will keep you informed as we move toward completing this transaction and provide updates on integration details.

Thank you for all of your continued hard work.

Sincerely,

Vince
