 Exhibit 4.1 
 EXECUTION COPY 
 FIRST SUPPLEMENTAL INDENTURE 

FIRST SUPPLEMENTAL INDENTURE (“Supplemental Indenture”) dated as of February 22, 2013, between PSS WORLD MEDICAL,
INC., a Florida corporation (the “Company”), and U.S. BANK, NATIONAL ASSOCIATION, a national banking association, as trustee (the “Trustee”). 
 RECITALS OF THE COMPANY 
 WHEREAS, the Company and the Trustee are parties
to that certain Indenture, dated as of August 4, 2008 (the “Indenture”), pursuant to which the Company issued its 3.125% Convertible Senior Notes due 2014 (the “Notes”); 

WHEREAS, the Company is a party to that certain Agreement and Plan of Merger, dated as of October 24, 2012, by and among the
Company, Palm Merger Sub, Inc. (“Merger Sub”), a Florida corporation, and McKesson Corporation (the “Merger Agreement”), pursuant to which, and subject to the terms and conditions contained in the Merger Agreement,
each share of Common Stock (a “Share”) will be converted into and shall thereafter represent only the right to receive $29.00 in cash (the “Cash Payment”); 

WHEREAS, the Cash Payment is to be paid to each holder of Shares without interest and less any applicable withholding taxes; 

WHEREAS, in connection with the foregoing, Section 15.06 of the Indenture provides that the Company shall execute a supplemental
indenture providing that each Note shall, without the consent of any holders of Notes, become convertible by reference only to the amount of Reference Property (as defined below); and 

WHEREAS, all conditions for the execution and delivery of this Supplemental Indenture have been complied with or have been done or
performed. 
 NOW, THEREFORE, THIS INDENTURE WITNESSETH: 

In consideration of the foregoing and for other good and valuable consideration, receipt of which is hereby acknowledged, the Company and
the Trustee agree as follows for the equal and ratable benefit of the holders of the Notes: 
 ARTICLE 1 

Definitions 
 Section 1.01. General. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Indenture. 







 ARTICLE 2 
 Agreements of Parties 
 Section 2.01 Conversion of Notes. In
accordance with Section 15.06 of the Indenture and the Officers’ Certificate, dated February 22, 2013, from and after the date of this Supplemental Indenture, the right to convert each $1,000 principal amount of Notes will be changed
to a right to convert such Notes by reference to the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”), which will be (i) cash equal to $1,413.73 per $1,000 principal amount of Notes based on a Conversion
Rate of 48.7493 in the case of a holder that elects to convert its Notes, in accordance with the Indenture, at any time from, and including, the date that the Merger Agreement becomes effective (the “Merger Agreement Effective Date”)
until, and including, the Business Day immediately preceding the Fundamental Change Repurchase Date to be specified in a Fundamental Change Repurchase Right Notice to be circulated in connection with the Merger Agreement Effective Date and
(ii) cash equal to $1,366.90 per $1,000 principal amount of Notes based on a Conversion Rate of 47.1342 in the case of a holder that elects to convert its Notes, in accordance with the Indenture, on or after the Fundamental Change Repurchase
Date. Holders of the Notes are entitled to receive at least as much cash per $1,000 principal amount of Notes as they would be entitled to receive if the full merger consideration were instead paid by converting each Share into the right to receive
$29.00 in cash. The provisions of the Indenture, as modified herein, shall continue to apply, mutatis mutandis, to the holders’ right to convert the Notes into the Reference Property.
