Filed by Syncor International Corporation Pursuant to Rule 425 under the Securities Act of 1933 Subject Company: Syncor International Corporation Commission File No. 0-8640 On December 4, 2002, Syncor International Corporation and Cardinal Health, Inc. issued the following joint press release: [GRAPHIC OMITTED] [GRAPHIC OMITTED] Contacts: David Verbraska - Media Allan Mayer Cardinal Health, Inc. Sitrick And Company (614) 757-3690 (310) 788-2850 Steve Fischbach - Investor Relations Bill Powell - Investor Relations Cardinal Health, Inc. Syncor International Corp. (614) 757-7067 (818) 737-4702 CARDINAL HEALTH AND SYNCOR ANNOUNCE AMENDED MERGER AGREEMENT o Exchange Ratio Lowered to 0.47 Cardinal Health Common Shares per Syncor Share o Merger to Create Leading U.S. Nuclear Pharmacy Services Business o Syncor Reaches Agreements with Department of Justice and Staff of Securities and Exchange Commission o Extensive Due Diligence Confirms Quality of Core Operations DUBLIN, OHIO and WOODLAND HILLS, CALIFORNIA - December 4, 2002 - Cardinal Health, Inc. (NYSE: CAH) and Syncor International Corporation (Nasdaq: SCOR) today announced that they have amended the June 14, 2002 merger agreement pursuant to which Cardinal Health will acquire Syncor in a stock-for-stock merger transaction. Under the terms of the revised agreement, Syncor stockholders will receive 0.47 of a Cardinal Health common share in exchange for each outstanding share of Syncor common stock. The original merger agreement had provided for a 0.52 exchange ratio. Cardinal Health further announced it is satisfied that it can move forward with the acquisition in a manner that is consistent with its high standards. Following the acquisition, Syncor's core domestic nuclear pharmacy business and the Central Pharmacy Services (CPSI) business of Cardinal Health will be combined, creating a leading provider in the fast growing and profitable nuclear pharmacy services business and furthering Cardinal Health's strategy of expanding its breadth of offerings to health care customers. Syncor also announced today that it had reached separate agreements with the U.S. Department of Justice (DOJ) and the staff of the U.S. Securities and Exchange Commission (SEC) related to the previously disclosed improper payments made by Syncor subsidiaries in certain foreign countries. "We have taken the steps and the time necessary to be fully satisfied that we can move forward with the acquisition of Syncor consistent with Cardinal Health's high standards of conduct," said Robert D. Walter, chairman and chief executive officer of Cardinal Health. "As a result of our further extensive domestic and international due diligence, which included investigations conducted by outside legal and forensic accounting teams, and the separate investigation conducted by the Syncor Special Committee, the issues have been identified and dealt with decisively. We believe that these actions, in conjunction with the agreements reached with the Department of Justice and SEC, bring these issues to closure and give us the confidence that Cardinal Health shareholders will be protected as we move forward to complete the acquisition." Upon completion of the acquisition, the Syncor operations will be integrated with Central Pharmacy Services (CPSI) to become the Nuclear Pharmacy Services business in the Pharmaceutical Technologies and Services (PTS) group of Cardinal Health. "Both Cardinal Health's CPSI business and Syncor's core domestic nuclear pharmacy business continue to deliver strong performance," said George Fotiades, who oversees the PTS group. "Syncor's domestic nuclear pharmaceutical operations represent an attractive fit with our existing nuclear pharmacy services offering, and will enhance our relationships with pharmaceutical manufacturers and biotech companies." Syncor will continue with previously announced plans to sell its imaging business and further rationalize its international operations. The agreement Syncor reached with the DOJ requires Syncor Taiwan, Inc., a subsidiary of Syncor, to plead guilty to one count under the Foreign Corrupt Practices Act (FCPA) and to pay a fine of $2 million relating to improper payments to employees of state-owned health care facilities in Taiwan. The agreement with the DOJ is subject to court approval of the plea agreement. The agreement Syncor reached with the staff of the SEC requires Syncor, without admitting or denying any findings, to consent to the entry of a cease and desist order prohibiting further violations of the FCPA and to pay a civil penalty of $500,000 relating to certain activities of Syncor's foreign subsidiaries. Syncor's board of directors will be required to appoint an independent consultant to review and make recommendations to improve Syncor's internal controls, record-keeping and financial reporting policies and procedures as they relate to the anti-bribery provisions of the FCPA. The agreement with the staff of the SEC requires approval by the Securities and Exchange Commission and the civil penalty is subject to court approval. "I am pleased that we can now focus on merging our domestic operations with Cardinal Health to create a world-class nuclear pharmacy services offering," said Robert Funari, president and chief executive officer, Syncor International. Cardinal Health and Syncor currently expect to complete the transaction in December 2002 or January 2003, with Cardinal Health issuing approximately 13 million shares to Syncor stockholders. Completion of the acquisition remains subject to customary conditions including, among others, approval of the revised merger agreement by the Syncor stockholders. As previously announced, Syncor will convene a stockholders meeting on December 6, 2002, for the sole purpose of adjourning the meeting to a later date so that additional information can be provided to stockholders. Syncor expects to mail additional information to its stockholders regarding the revised merger agreement, a new stockholders meeting date and other important information as soon as the materials are filed and cleared by the corporation finance division of the SEC.

As a result, the merger between our two companies is now expected to be completed in late December or January. At the same time, we have reached separate agreements with the Department of Justice and the staff of the Securities and Exchange Commission that are intended to settle the legal issues raised with those agencies in connection with those payments. Throughout this challenging period, that is now hopefully drawing to a close, we have been and remain determined to protect the reputation of the thousands of honest, ethical professionals like you who have made Syncor the unquestioned leader in its field. As a result of your dedication and continued focus, our SPS business is in the process of turning in another excellent year. I continue to be extremely excited about the merger with Cardinal Health and look forward to taking advantage of the opportunities and synergies of merging with Cardinal Health and CPSI. We will be able to offer our customers an even larger portfolio of products and services as we join Cardinal Health and become part of the Pharmaceutical Technologies and Services group headed by George Fotiades. I have attached a note from Bob Walter to Cardinal Health employees for your information. Cardinal Health recently embarked upon a company-wide branding strategy through which all of the divisions of the company will be going to market under the Cardinal Health name effective January 1, 2003. As a result of this initiative and the advantages this strategy will offer us in the marketplace, after completion of the merger, the integrated Syncor-CPSI business will also go to market under the Cardinal Health name. I want to ask your support as we redouble our efforts towards successfully integrating our pharmacy business with CPSI's. The more quickly and efficiently we can complete the process, the better we can position the newly combined business for future growth and value for our customers. The integration teams will be seeking your critical feedback as we continue our momentum in our integration activities and integration plans. I will continue to keep you informed as we make progress. In the meantime, I would like to thank you once again for your hard work and loyalty. Your integrity and professionalism were--and continue to be--the key to our efforts to protect and maintain Syncor's reputation for honesty, quality, and service.
