Subject:	Airgas Board of Directors Responds to Air Products’ Tender Offer

This morning, we announced that Airgas’ Board of Directors, after careful consideration with its independent financial and legal advisors, unanimously voted to reject the unsolicited tender offer launched by Air Products on February 11, because it grossly undervalues Airgas and is not in the best interests of Airgas’ stockholders. Accordingly, the Board has recommended that Airgas stockholders not tender their shares into Air Products’ offer. A copy of the press release we issued, which provides more detail on the Board’s rationale, is attached.

If you own Airgas shares, whether in a personal account, through the Employee Stock Purchase Plan, or in the 401(k) plan, we urge you to follow the Board’s recommendation by not tendering your shares into the Air Products offer.

The Air Products tender offer is scheduled to expire on April 9, 2010, unless extended. In addition, there are many conditions in the offer that make it highly uncertain. We intend to continue our strategic course and create superior shareholder value by operating our business at peak performance, and as I’ve mentioned before, the best approach for each of us is to meet and exceed our customers’ needs.

We are committed to keeping you informed throughout this process. If you have questions, please feel free to reach out to your manager and/or review the materials available through the link titled “Air Products’ Unsolicited Proposal” on Airnet or www.airgas.com, which will be updated as we move forward.

As this process unfolds, Airgas will likely continue to be the subject of discussion and speculation in the media. I want to stress that our business objectives remain unchanged. We remain focused on serving our customers and enhancing the stockholder value that we have worked so hard to build through the years.

Should you receive any media inquiries, please forward them to Jay Worley, Vice President–Communications and Investor Relations, at 610-902-6206 or jay.worley@airgas.com, and all investor inquiries should go to Barry Strzelec, Manager-Investor Relations, at 610-902-6256 or barry.strzelec@airgas.com.

As a reminder, throughout this process it is business as usual for all of us here at Airgas. Please stay focused on your day-to-day responsibilities, and continue meeting and exceeding the needs of our customers. Your Board and management team thank you all for your commitment to Airgas.

Sincerely,

Peter McCausland

Chairman and Chief Executive Officer

FORWARD-LOOKING STATEMENTS

This communication may contain statements that are forward looking, as that term is defined by the Private Securities Litigation Reform Act of 1995, as amended, or by the SEC in its rules, regulations and releases. These statements include, but are not limited to: our having strong prospects for organic and acquisition growth in the coming years; the economy just beginning its recovery; the view that under the terms of Air Products’ proposal, our stockholders would sacrifice real value and opportunity; our belief that a combination of our two companies could destroy rather than create value; our belief that Air Products’ tender offer would be highly likely to be subject to substantial delays related to U.S. antitrust clearance; and our prospects for continued growth and stockholder value creation. We intend that such forward-looking statements be subject to the safe harbors created by the Private Securities Litigation Reform Act of 1995, as amended. All forward-looking statements are based on current expectations regarding important risk factors and should not be regarded as a representation by us or any other person that the results expressed therein will be achieved. Airgas assumes no obligation to revise or update any forward-looking statements for any reason, except as required by law. Important factors that could cause actual results to differ materially from those contained in any forward-looking statement include: adverse changes in customer buying patterns resulting from further deterioration in current economic conditions; weakening in the operating and financial performance of our customers, which can negatively impact our sales and ability to collect our accounts receivable; postponement of projects due to the recession; customer acceptance of price increases; the success of implementing and continuing our cost reduction programs; supply cost pressures; increased industry competition; our ability to successfully identify, consummate, and integrate acquisitions; our ability to achieve acquisition synergies; our continued ability to access credit markets on satisfactory terms; significant fluctuations in interest rates; increases in energy costs and other operating expenses eroding planned cost savings; higher than expected implementation costs of the SAP system; conversion problems related to the SAP system that disrupt our business and negatively impact customer relationships; the impact of tightened credit markets on our customers; the impact of changes in tax and fiscal policies and laws; the potential for increased expenditures relating to compliance with environmental regulatory initiatives; the impact of new environmental, healthcare, tax, accounting, and other regulation; continued potential liability under the Multiemployer Pension Plan Amendments Act of 1980 with respect to our participation in or withdrawal from multi-employer pension plans for our union employees; the extent and duration of current recessionary trends in the U.S. economy; the effect of catastrophic events; political and economic uncertainties associated with current world events; and other factors described in Airgas’ reports, including its March 31, 2009 Form 10-K, subsequent Forms 10-Q, and other documents filed by Airgas with the SEC.
