On May 18, 2009, Cardinal Health, Inc. (the “Company”) filed a Definitive Proxy Statement for a Special Meeting of Shareholders to be held on June 23, 2009 (the “Definitive Proxy Statement”), which contains a proposal to approve a stock option exchange program for employees other than the Company’s directors, named executive officers and former employees (the “Proposed Option Exchange Program”). In connection with the Proposed Option Exchange Program, the Company is herewith filing the Definitive Proxy Statement.

The Definitive Proxy Statement does not constitute an offer to holders of the Company’s outstanding stock options to exchange those options.

The Proposed Option Exchange Program has not yet commenced. The Company will file a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission (“SEC”) upon the commencement of the Proposed Option Exchange Program. Persons who are eligible to participate in the Proposed Option Exchange Program should read the Tender Offer Statement on Schedule TO and other related materials when those materials become available, because they will contain important information about the Proposed Option Exchange Program.

The Company’s shareholders and option holders will be able to obtain the written materials described above and other documents filed by the Company with the SEC free of charge from the SEC’s website at www.sec.gov. In addition, shareholders and option holders may obtain free copies of the documents filed by the Company with the SEC on the Company’s website at the investor page on www.cardinalhealth.com.
