EMPLOYMENT AGREEMENT

THIS AMENDMENT NO. 2 (the “Amendment”), effective as of June 16, 2000, by and between PSS World Medical, Inc., a Florida corporation (the “Company”), and Edward D. Dienes (“Executive”), amends that certain Employment Agreement, dated as of April 1, 1998, by and between the Company and Executive, as heretofore amended (the “Employment Agreement”).

“(iii) after the occurrence of a Change of Control, the Company’s requiring Executive to be based at any office or location other than in the city in which he was based on the date of the Change in Control or the Company’s requiring Executive to travel on Company business to a substantially greater extent than required immediately prior to the Effective Date;”

2. As amended hereby, the Employment Agreement, as heretofore amended, shall be and remain in full force and effect.

IN WITNESS WHEREOF, the parties have executed this Amendment No. 2 as of the date first above written.
