FOR RELEASE:        IMMEDIATELY

    AIRGAS AGREES TO ACQUIRE BOC'S U.S. PACKAGED GAS BUSINESS

RADNOR, PA - April 2, 2004  -- Airgas, Inc. (NYSE: ARG) today
announced it has signed a definitive asset purchase agreement to
acquire most of the U.S. packaged gas business of The BOC Group,
Inc. (NYSE: BOX) in a transaction valued up to $200 million.

The companies first announced a letter of intent on January 27,
2004 and the FTC has since completed its regulatory review.  The
transaction, which is subject to customary closing conditions, is
expected to close on or about July 31, 2004.

The acquisition will include about 120 locations in 21 states,
including retail stores, warehouses, fill plants and other
operations involved in distributing packaged industrial,
specialty and medical gases, as well as welding equipment and
supplies sold through BOC's stores and distributors.

Airgas intends to offer employment to more than 1,000 employees
aligned with the operations, which generated about $240 million
in revenues in fiscal 2003.  Approximately 65 percent of the
revenues were from gas sales and cylinder rent, with the
remainder from welding hardgoods and supplies.

The transaction will exclude packaged electronic gases, helium
and hydrogen delivered in tube trailer or in liquid form, and
bulk gases, including bulk medical and bulk gases supplied to
BOC's distributors.  The transaction also will not affect BOC's
merchant liquid and tonnage/on-site business in North America and
its packaged gases businesses in other parts of the world.



"This is a strategic opportunity in our core business that will
improve our market position in the Midwest, Northeast and
Southeast portions of the United States, and add our first
presence in Hawaii," said Airgas Chairman and CEO Peter
McCausland.  "These added sites will help us grow our core
business, branch by branch, through a strong regional company
network.  The transaction also strengthens our position in two
key growth areas, specialty and medical gases."

In addition to the planned acquisition, the companies will sign
reciprocal long-term supply agreements.  Airgas will become the
supplier for a substantial portion of BOC's resale packaged gas
needs.  BOC will supply liquid bulk gases to support the
operations it is selling to Airgas.

Most of the acquired operations and related personnel will be
integrated within Airgas' regional company structure.  All of
BOC's Hawaiian operations will become an additional Airgas
regional company.  Operations in North Carolina and southern
Virginia employing about 40 employees, will be sold to National
Welders Supply Company, Inc., a joint venture between Airgas and
the Turner family of Charlotte, NC.  For more information on the
sites to be acquired and future alignment, go to

"Airgas has a proven track record of successfully integrating
both large and small acquisitions and we are confident in our
ability to execute this transaction.  Since completing the Air
Products acquisition two years ago, we have announced nine add-on
transactions.  We also have paid down the majority of this
acquisition debt.  We are well positioned financially and able to
finance this acquisition entirely with senior debt," said
McCausland.

The Company expects the acquired business to be $0.02-$0.04
accretive to EPS in the first 12 months, with up to $0.02 per
share toward the end of FY05 and the balance in early FY06. A
slide presentation with additional details regarding this
transaction is available at http://www.shareholder.com/arg/slides.cfm.
