Airgas

We continue to protect our shareholders from Air Products’ grossly inadequate offer

Airgas will entertain an appropriate offer; Air Products has failed to make any such offer

Meeting date consistent with Delaware law

2010 annual meeting is scheduled for the first full week after the Labor Day holiday in order to maximize shareholder participation

AIR PRODUCTS Risk Metrics Meeting

Airgas’ delay tactics not in shareholder interest

- Airgas; first action in response to our public offer was to pursue litigation

- Airgas has refused to discuss any aspect of our offers despite our clearly stated flexibility regarding price and form of consideration

- Airgas has refused to form an independent Board committee despite possibility of founder, Chairman and CEO’s interests not being aligned with other shareholders

- Airgas amended bylaws on April 7, 2010, in order to delay its 2010 annual meeting date

Airgas continues to deprive shareholders of their right to decide

- Refused to rescind “poison pill” shareholder rights plan

- Rejected Air Products’ request to hold 2010 annual meeting no later than August 18, 2010 (one year anniversary of 2009 annual meeting)

- Rejected Air Products’ request that director nominees not elected by shareholders at 2010 annual meeting not be reappointed for at least three years

Airgas’ Chairman and CEO is the largest holder of Airgas stock. His interests are squarely aligned with our shareholders, except for Air Products

LOGO

Airgas

Air Products has resorted to using dated financial metrics in an attempt to support its grossly inadequate offer

Air Products has ignored Airgas’ most recent results and based their valuation on Airgas’ LTM March EBITDA and net debt in an attempt to negate the impact of Airgas’ improved operating performance

LTM EBITDA and balance sheet information as of 03/31/2010

Over the last quarter, the increase in LTM EBITDA and decrease in net debt imply ~$4.40 of incremental value per share based on APD’s implied proposed, and dated, 10.9x LTM EBITDA multiple

Airgas’ LTM EBITDA increased $26 million and net debt decreased $94 million from the LTM March period to the LTM June period

Air Products based its valuation on trough earnings, which does not give Airgas credit for its strong operating performance since the initial offer

By seeking to force an opportunistic transaction early in Airgas’ earnings recovery, Air Products’ offer is attempting to transfer more than one turn of EBITDA in value from Airgas shareholders to Air Products

Airgas

Air Products’ incomplete and disingenuous analysis once again is designed to mislead

Non-Comparable Precedents

BOC Gazy and Air Liquide Industrial Gas are not comparable in size and scope to Airgas

Air Products’ proposal for Airgas implies a ~$7 billion transaction value; BOC Gazy and Air Liquide Industrial Gas were ~$500 million in transaction value

Airgas’ national footprint drives synergy potential. We believe it is the “last house on the peninsula” and can’t be replicated organically

The BOC Gazy and Air Liquide Industrial Gas were subscale regional consolidation plays

* See attached reconciliation of non-GAAP measures.

Excluded Transaction

The last time Air Products attempted to acquire a strategic gas company of scale

(BOC Group) it offered 11.4x LTM EBITDA LTM EBITDA. APD has excluded the transaction from this analysis

The implied June 30 LTM EBITDA multiple for Airgas is 10.4x. The implied Sept. 30 LTM EBITDA multiple for Airgas is 10.0x, which compares to 10.9x LTM March 30 EBITDA

Airgas

Airgas’ SSS growth assumptions have been reaffirmed by recent performance

Last quarter’s SSS growth of 6% is in line with performance in the prior recovery;

Current performance continues to track forecast

No real direct exposure to residential construction, commercial real estate and the retail segments of the economy

We have just successfully implemented a June 1st nationwide price increase

Airgas averaged annual SSS growth of 7% in the last economic expansion (2003-2008)

There are ~900 independent packaged gas businesses in the U.S. accounting for ~50% of the market; as well as many attractive opportunities in adjacencies and alternate geographies

Our forecast is based on: SSS growth comparable to prior recoveries; demonstrated operating leverage; continued focus on cutting operating costs; maintaining a higher margin business mix; realization of anticipated returns on capital investments made in recent years

AIR PRODUCTS

Risk Metrics Meeting

Airgas’ CY 2012 earnings forecast is based on aggressive sales growth assumptions

Assumes same store sales (SSS) growth rate of 7%, higher than the 6% SSS growth rate achieved in the significantly stronger 2003 - 2005 recovery

Current economic recovery is weaker than 2003 - 2005 due to:

Significantly higher unemployment

Non-existent housing recovery

Deflationary pressures

Less favorable pricing environment today vs. 2003 - 2005

Airgas’ historical net sales growth has largely been driven by acquisitions not organic growth

SSS growth average of only 2% from 2001 - FY 2010

SSS growth has contributed only ~20% of Airgas’ increase in net sales over the past 10 fiscal years on average - acquisitions accounted for ~80%

Airgas’ estimated acquired sales CAGR of ~3% is lower than its SSS growth expectations

No sizeable acquisition since Airgas bought Linde’s U.S. gas business in 2007, suggesting a more challenging environment for attractive acquisitions

Airgas’ aggressive CY 2012 earnings forecast should be appropriately risk-adjusted

LOGO

Airgas

Air Products has misrepresented Analysts’ views of our standalone valuation

Air Products mischaracterizes analysts’ views of temporary, technical trading dynamics relative to fundamental, stand-alone valuation To support these claims, Air Products selectively cites out-dated reports

The most recent analyst report to address Airgas’ stand-alone valuation notes:

“…if there were no offer and Airgas was being valued on its earnings power alone based on our forecasts and its own estimates of SAP contribution, we would probably estimate a fair value of $65–$70. And at a minimum, we think Air Products should pay a control premium on top of that”

– Holden Lewis, BB&T, September 3, 2010

Pre-offer analyst consensus 12-month price target was $55 with a consensus NTM EPS estimate of $2.93 – The current consensus NTM EPS estimate is $3.35

The market believes the offer undervalues Airgas

Our shares have closed at a premium to APD’s proposals every day, with the exception of one, since the initial offer

AIR PRODUCTS

Risk Metrics Meeting

Only Airgas’ Management and Board believe our price is “ not even close”, but…

The market believes we are close on price

Stock has traded at a volume-weighted average price of $62.58 prior to our increase and at a volume-weighted average price of $65.35 since our increase

– It is our offer that is driving price, not a view of the fundamental value of Airgas

Analysts believe we are close on price

Analyst estimates of standalone value of $46.00

Not a single analyst has a “Buy” rating on Airgas stock

Comparison to historical transactions demonstrates we are close price

Premium to unaffected price of 46% well above averages

Multiple of 10.9x LTM EBITDA at time of $63.50 offer is well above median multiple precedent transactions

And Airgas’ future earnings forecast indicates we are close on price

Applying any reasonable multiple and discount rate to Airgas’ aggressive forecast earnings of $4.20 in CALENDAR YEAR 2012 yields values below our current offer price

- This is without risk-adjusting Airgas’ aggressive earnings forecast

Consensus analyst estimates corroborate our achievable forecast

Analysts typically suspend price targets and ratings during deals; however recent reports indicate mid-to-high $60s per share in fundamental value

The Company believes the above adjusted operating margin and adjusted EBITDA margin computations help investors assess the Company’s operating performance without the impact of charges associated with the Company’s withdrawal from multi-employer pension plans and costs related to Air Products’ unsolicited takeover attempt. Non-GAAP numbers should be read in conjunction with GAAP financial measures, as non-GAAP metrics are merely a supplement to, and not a replacement for, GAAP financial measures. It should be noted as well that our adjusted EBITDA metric may be different from adjusted EBITDA metrics provided by other companies. Certain reclassifications have been made to prior period financial statements to conform to the current presentation.
