CARDINAL HEALTH, INC. 
 4.900%
Note due 2045 
 This Note is one of a duly authorized issue of debentures, notes, bonds or other evidences of indebtedness of the Issuer
(hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an indenture dated as of June 2, 2008 (herein called the “Indenture”), duly executed
and delivered by the Issuer to The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the
rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate
principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise
vary as in the Indenture provided. This Note is one of a series designated as the 4.900% Notes due 2045 of the Issuer, limited in initial aggregate principal amount to $450,000,000 (collectively, the “Notes”). The Issuer may, at any
time, without notice to or the consent of the Holders of the Securities, issue further notes having the same ranking and the same interest rate, maturity and other terms as the Notes (other than the date of issuance and, under certain circumstances,
the first interest payment date following the issue date of such further notes). Any such further notes, together with this Note, will form a single series of Securities under the Indenture. 

 

	1.	Principal and Interest 

 The Notes will mature on September 15, 2045. 

In case an Event of Default with respect to the Notes, as defined in the Indenture, shall have occurred and be continuing, the principal
hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 

Interest shall be computed on the basis of a 30-day month and a 360-day year. 

 

	2.	Amendment; Supplement; Waiver 

 The Indenture contains provisions permitting the Issuer
and the Trustee, with the consent of the Holders of not less than a majority in the aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class), evidenced as provided in the Indenture, to
execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the
Securities of each such series; provided, however, that no such supplemental indenture shall (i) extend the final maturity of any Security, or reduce the principal amount thereof or any premium thereon, or reduce the rate or extend the time of
payment of any interest thereon, or reduce or 







 
impair or affect the rights of any Holder to institute suit for the payment thereof or any right of repayment at the option of the Holder, without the consent of the Holder of each Security so
affected, or (ii) reduce the aforesaid percentage of Securities, the Holders of which are required to consent to any such supplemental indenture, without the consent of the Holder of each Security affected. It is also provided in the Indenture
that, with respect to certain defaults or Events of Default regarding the Securities of any series, prior to any declaration accelerating the maturity of such Securities, the Holders of a majority in aggregate principal amount Outstanding of the
Securities of such series (or, in the case of certain defaults or Events of Default, all or certain series of the Securities) may on behalf of the Holders of all the Securities of such series (or all or certain series of the Securities, as the case
may be) waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default in the payment of the principal of or premium, if any, or interest on any of the Securities. Any such consent
or waiver by the Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and any Notes which may be issued in exchange or substitution
herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes. 
  

	3.	Optional Redemption 

 The Notes are redeemable, prior to March 15, 2045 (six months
prior to their maturity), in whole at any time or, in part from time to time, at the Issuer’s option, at a redemption price equal to the greater of: 

(1) 100% of the principal amount of the Notes to be redeemed, or 

(2) as determined by a Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest thereon
that would be due if the Notes matured on March 15, 2045 (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate plus 30 basis points, 
 plus, in each case, accrued and unpaid interest, if any, on the amount of the Notes being redeemed to, but
excluding, the date of redemption. 
 The Issuer may also redeem some or all of the Notes on or after March 15, 2045 (six months prior to their
maturity), at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption. 

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 

“Comparable Treasury Issue” means the United States Treasury security selected by a Quotation Agent as having a maturity comparable
to the remaining term of 

  
 2 








 
the Notes (assuming for this purpose that the Notes matured on March 15, 2045) to be redeemed that would be utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining terms of such Notes. 
 “Comparable
Treasury Price” means, with respect to any redemption date, (1) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer. 

“Reference Treasury Dealer” means (1) Barclays Capital Inc., Goldman, Sachs & Co., Merrill Lynch, Pierce,
Fenner & Smith Incorporated and a primary treasury dealer selected by Mitsubishi UFJ Securities (USA), Inc. (or their respective affiliates that are “Primary Treasury Dealers”) and their respective successors; provided, however,
that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), the Issuer shall substitute therefor another Primary Treasury Dealer, and (2) any
other Primary Treasury Dealer selected by the Issuer. 
 “Reference Treasury Dealer Quotation” means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time on the third Business Day preceding such redemption date. 

Notice to Holders of Notes to be redeemed will be delivered electronically or by first-class mail at least 30 and not more than 60 days prior
to the date fixed for redemption. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are
to be redeemed, the Trustee shall select, in such manner as it shall deem appropriate and fair, the Notes to be redeemed in whole or in part. 
  

	4.	Special Mandatory Redemption 

 In the event that the Principal Closing (as defined in the
Cordis Purchase Agreement) has not occurred on or prior to March 31, 2016, or the Cordis Purchase Agreement is terminated, the Issuer will be required to redeem all outstanding Notes on the Special Mandatory Redemption Date at a redemption
price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”). Notwithstanding the
foregoing, installments of interest on the Notes that are due and payable on interest payment dates falling on or prior to the Special Mandatory Redemption Date will be payable on such interest payment dates to the registered Holders as of the close
of business on the relevant record dates in accordance with the Notes and the Indenture. 

  
 3 








 The Issuer will cause the notice of special mandatory redemption to be delivered electronically
or mailed, with a copy to the Trustee, within ten Business Days after the occurrence of the event triggering the special mandatory redemption to each Holder at its registered address. If funds sufficient to pay the Special Mandatory Redemption Price
of the Notes to be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee or a paying agent on or before such Special Mandatory Redemption Date, and certain other conditions are satisfied, on and after such Special
Mandatory Redemption Date, the Notes will cease to bear interest. 
 “Cordis Acquisition” means the purchase by the Issuer of
certain assets of the Cordis business of Johnson & Johnson for a purchase price of $1,944 million in cash, subject to certain adjustments on a cash-free, debt-free basis. 

“Cordis Purchase Agreement” means the Stock and Asset Purchase Agreement, dated March 1, 2015 between the Issuer and Ethicon,
Inc. 
 “Special Mandatory Redemption Date” means the earlier to occur of (1) May 30, 2016, if the Cordis Acquisition
has not occurred on or prior to March 31, 2016, or (2) the 60th day (or if such day is not a Business Day, the first Business Day thereafter) following the termination of the Cordis Purchase Agreement for any reason. 

 

	5.	Repurchase at the Option of Holders Upon a Change of Control 

 Upon the occurrence of a
Change of Control Repurchase Event, unless all Notes have been called for redemption pursuant to paragraph 3 of this Note or the Issuer has been required to redeem such Notes pursuant to paragraph 4 of this Note, each Holder of the Notes shall have
the right to require the Issuer to repurchase all or any part (equal to $2,000 or in integral multiples of $1,000 in excess thereof) of such Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes
repurchased plus accrued and unpaid interest thereon, if any, to, but excluding, the date of repurchase (the “Change of Control Payment”). 

Within 30 days following any Change of Control Repurchase Event or, at the Issuer’s option, prior to any proposed Change of Control, but
after the public announcement of the proposed Change of Control, the Issuer shall deliver, or cause to be delivered, a notice (a “Change of Control Offer”) to each Holder, with a copy to the Trustee, describing the transaction or
transactions that constitute or may constitute the Change of Control Repurchase Event and shall specify, without limitation, the following: 

(1) that the Change of Control Offer is being made and that all Notes tendered will be accepted for payment; 

(2) the Change of Control Payment and the purchase date, which shall be a Business Day no earlier than 30 days and no later than 60 days from
the date such notice is delivered (the “Change of Control Payment Date”);

 (3) the CUSIP numbers for the Notes; 

(4) that any Note not tendered will continue to accrue interest; 

(5) that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of
Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (6) that Holders whose Notes of any series are
being purchased only in part will be issued new Notes of such series equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion will be equal to $2,000 in principal amount or in integral multiples of
$1,000 in excess thereof; and 
 (7) if the notice is delivered prior to the date of consummation of the Change of Control, that the Change
of Control Offer is conditioned on the Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date. 

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to
the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the
provisions hereof, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations hereunder by virtue of such conflict. 

On the Change of Control Payment Date, the Issuer will, to the extent lawful: 

(1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; 

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and

stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. 
 The paying agent shall promptly
deliver to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book entry) to each Holder a new Note of the same series equal in
principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or in integral multiples of $1,000 in excess thereof. 

The Issuer shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if a third party makes the Change
of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change
of Control Offer.

or (3) the first day on which a majority of the members of the Issuer’s Board of Directors cease to be Continuing Directors. Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (i) the
Issuer becomes a wholly owned subsidiary of a holding company and (ii) the Holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the Holders of Voting Stock immediately prior to
that transaction. 
 “Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment
Grade Rating Event.

“Rating Agency” means (i) each of Fitch, Moody’s and S&P; and (ii) if any of Fitch, Moody’s or S&P
