Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The reporting person exercised 5,223 stock options granted on May 15, 1996. Such options would have expired on May 15, 2006 if not exercised. In light of the expiration date, the reporting person exercised all such options and delivered to the Company a total of 1,479 previously-owned shares as payment of the exercise price.
(2) The filing of this statement shall not be construed as an admission that the reportin person is, for the purpose of Section 16 of the Securities Exchange Act of 1934, as amended, the beneficial owner of these shares.
(3) Stock option granted pursuant to the Cardinal Health, Inc. Equity Incentive Plan.
(4) Stock option was disposed of in connection with its exercise for no additional consideration beyond the option shares.
(5) Stock option granted pursuant to the Cardinal Health, Inc. Outside Directors Equity Incentive Plan.
(6) Stock option granted for compensation as Chief Financial Officer on an interim basis in lieu of cash, salary, bonus or other incentive compensation.
(7) Phantom stock held under the Company's Deferred Compensation Plan (the "Plan") was previously reported as common shares on Table 1 to Form 4 because, among other things, the Plan only permitted payment of amounts credited to a participant's Company stock account under the Plan in common shares. The Plan was amended in December 2005 to permit payment of amounts credited to a participant's account either in cash or in common shares at the election of the participant. Accordingly, shares of phantom stock held under the Plan are now reported on Table II.
(8) Each share of phantom stock is the economic equivalent of one common share. The shares of phantom stock become payable, in cash or common shares, at the election of the reporting person, at least six months after termination from board service.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
