4.1 Vesting. A Participant always will be 100 percent vested in amounts credited to his Account as Deferred Compensation Credits, Deferred Cash Equivalent Credits, Matching Credits made on or after January 1, 2005, Prior Plan Credits and earnings allocable thereto. The Participant or his Beneficiaries shall be entitled to benefits from Matching Credits made prior to January 1 2005, Employer Contribution Credits and Social Security Supplement Credits allocated to his Account by the Employer, and earnings thereon, only upon satisfaction of the vesting requirements of this Article IV. The Participant shall become 100 percent vested in his Account upon his Retirement, death, Total Disability or upon a Change of Control of the Company. If the Participant has a Separation from Service with the Employer for any reason other than Retirement, death, Total Disability, or pursuant to a Change of Control, all rights of the Participant, his Beneficiaries, executors, administrators, or any other person to receive benefits under this Plan derived from amounts credited as Matching Credits made prior to January 1, 2005, Employer Contribution Credits and Social Security Supplement Credits shall vest as of the date that the Participant has completed three Years of Service with the Employer. A Year of Service for this purpose means a period of 12 consecutive calendar months during which the Participant was employed by the Employer, defined to include all members of a controlled group of corporations or other business entities within the meaning of Code Sections 414(b) and (c) that includes Cardinal Health, Inc. If a Participant has a Separation from Service before that date (other than due to a Change of Control, Retirement, death or Total Disability), all Matching Credits made prior to January 1, 2005, Employer Contribution Credits and Social Security Supplement Credits shall be forfeited. If the Participant has a Separation from Service but is subsequently re-employed by the Employer, no benefits forfeited hereunder shall be reinstated unless otherwise determined by the Company in its sole discretion.
4.2 Confidentiality and Non-Competition Agreement. In its discretion, the Employer may require any Eligible Employee selected to become a Participant in the Plan to execute a Confidentiality and Non-Competition Agreement with the Employer in consideration of the benefits to be provided hereunder.
