2003 EMPLOYEE STOCK PURCHASE PLAN

Amendment No. 3
Effective January 29, 2013

RESOLVED, that Section 6(d) of the Amended and Restated 2003 Employee Stock
Purchase Plan be and it hereby is amended to read in its entirety as follows:
"(d) Each option shall provide that shares purchased pursuant to the Plan with
amounts withheld from Compensation otherwise payable on or after April 1, 2012,
may not be sold or otherwise transferred during the "Restricted Period"
applicable to them, except as hereafter provided. The Restricted Period is the
period beginning on the Enrollment Date as of which the shares were purchased
and ending at the close of business on the last day of employment with Airgas,
Inc. and its affiliates, or at the close of business one year after that
Enrollment Date, whichever day is earlier. The restriction applicable to shares
purchased as of a particular Enrollment Date shall lapse, and shall not be
restored, if the closing price of a share of the Common Stock on the New York
Stock Exchange for five consecutive Trading Days during the Restricted Period is
less than the purchase price for such shares determined pursuant to the Plan."
