Airgas Completes New Credit Agreement.

RADNOR, Pa. -- Airgas, Inc. (NYSE:ARG) today announced it has amended and restated its senior credit facility with a syndicate of banks. The five-year $1.6 billion senior unsecured credit facility (the "Credit Agreement"), consists of a US$966 million and C$40 million (the US dollar equivalent of $34 million) revolving credit line and a $600 million term loan. The drawing on the term loan is contingent on the maturity of $100 million of the 7.75% medium term notes on September 15, 2006, and the closing of certain acquisitions.

Airgas is currently contemplating several acquisitions, which, if completed, would be funded with the borrowings that are available under the Credit Agreement.

The Credit Agreement supersedes the credit agreement dated January 14, 2005, (the "2005 Agreement"), which would have matured in January 14, 2010 and permitted the company to borrow up to the equivalent of $428 million. The company's initial borrowings under the Credit Agreement total $191 million. The current borrowing rate is LIBOR plus 75 basis points, down from LIBOR plus 95 basis points under the 2005 Agreement. The covenants under the new Credit Agreement are generally similar to those in the 2005 Agreement. The Company expects to file the Credit Agreement as an Exhibit to the 10-Q for the period ended September 30, 2006.

Airgas also announced that as a result of the acquisitions under consideration, it suspended the three-year share repurchase plan it initiated in November 2005. The Company will focus on using its cash flow to pay down debt, grow its dividend, and to continue investing in growth opportunities, including future acquisitions.
