Filed by Cardinal Health, Inc. Pursuant to Rule 425 under the Securities Act of 1933 Subject Company: Syncor International Inc. Commission File No. 000-08640 To: All Cardinal Health Employees From: Bob Walter Re: Developments at Syncor I'm writing to update you on some recent developments with regard to our previously-announced acquisition of Syncor. As part of our ongoing due diligence review, we uncovered certain improper payments that Syncor has made in foreign countries. We reported our findings immediately to Syncor, whose Board of Directors contacted the proper government officials. I thought you might like to see the two news releases that were distributed about this issue early this morning, which are attached - one from Syncor and one from Cardinal Health. While it is difficult to know yet what effect this development may have on our plans to acquire Syncor, there are a few things I want to make clear: * While I am very disappointed with this development, it is an important example of how thoroughly we review the business operations, financial practices and other aspects of any new businesses we seek to acquire. And, frankly, ethics and cultural values are just as important to us as operational or financial issues. It's the reason we take our time with due diligence - we want to make sure we know everything we can about any business we want to make part of Cardinal Health. * We are continuing to monitor this situation carefully. Our agreement with Syncor is subject to a number of conditions that need to be satisfied before we close. At this time, we haven't concluded whether those conditions will be satisfied. * Our CPSI nuclear pharmacy business has been -- and continues to be -- an important part of our business strategy. The reason we want to further invest in this business is because we believe we can create better value for customers by expanding our core set of products and services. We remain committed to this business strategy. Growth is an important part of our strategy at Cardinal Health. But, I can assure that any acquisitions made in support of that growth must meet our criteria for integrity and ethics. This is a very complex situation and it is not a good idea to speculate on the ultimate outcome. This issue should not be discussed with customers, suppliers or others outside of Cardinal Health. We'll keep you posted on any new developments as they occur. ********************* Except for historical information, all other information in this news release consists of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
