As of April 26, 2016, there was \\$1,550,000,000 aggregate principal amount of Affected Notes outstanding.

As previously announced, on November 17, 2015, Airgas, L'Air Liquide S.A., ("Air Liquide") and AL Acquisition Corporation ("Merger Sub") signed an Agreement and Plan of Merger pursuant to which Merger Sub will be merged with and into Airgas (the "Merger"). The Merger remains subject to receipt of necessary antitrust approvals and other customary conditions and is expected to be completed, and the certificate of merger filed, in the second calendar quarter of 2016. In connection with the Merger, Airgas is making the consent solicitation at the request and expense of Air Liquide.

The consent solicitation will expire at 5:00 p.m., New York City time, on May 9, 2016, unless terminated or extended by the Company (the "Expiration Date"). The consent solicitation is conditioned on the receipt from holders of Affected Notes as of 5:00 p.m., New York City time, on April 25, 2016 (the "Record Date") of at least a majority in aggregate principal amount of the outstanding Affected Notes, voting together as a single class. The consent solicitation is also conditioned on customary closing conditions, each of which may be waived by Airgas at any time.

Airgas will, after the Expiration Date and upon (i) the satisfaction or waiver of all terms and conditions to the consent solicitation and (ii) the closing of the Merger, promptly pay to each holder of Affected Notes who has delivered (and not revoked) a valid consent in favor of the proposed amendments prior to the Expiration Date a cash payment of \\$1.50 for each \\$1,000 principal amount of Affected Notes in respect of which such consent has been delivered.

If the Merger is completed, Air Liquide may elect to provide an unconditional guarantee (the "Air Liquide Guarantee") of the Company's payment obligations under the indenture dated as of May 27, 2010 between the Company and U.S. Bank National Association, as trustee, as amended and supplemented from time to time (the "Indenture") and the Notes? provided, however, that Air Liquide has no obligation to do so. If Air Liquide provides the Air Liquide Guarantee, Air Liquide will provide its periodic and current reporting (under applicable French law) in lieu of Airgas's existing periodic and current reporting obligations, which reporting obligations will not be applicable at any time and for any period during which the Air Liquide Guarantee is in force.

The consent solicitation may be amended, extended, abandoned or terminated at the option of Airgas. For a complete statement of the terms and conditions of the consent solicitation, holders of the Affected Notes should refer to the consent solicitation statement, dated as of April 26, 2016, which is being sent to holders of the Affected Notes as of the Record Date.

Insofar as a redemption notice with respect to the Company's \\$250,000,000 2.950% Notes due 2016 has been issued, such notes will not be affected by the proposed amendments and are therefore excluded from the consent solicitation. Such Notes will be redeemed in full on May 15, 2016.
