Dear Mr. McGlade:

We have received your letter dated October 29th and are certainly prepared to meet with you if there is a reasonable opportunity to obtain an appropriate value for the Airgas shareholders.

In our last letter, we indicated that our board of directors was of the unanimous view that the value of Airgas in any sale is meaningfully in excess of $70 per share. To provide greater clarity, the board has unanimously concluded that it believes that the value of Airgas in a sale is at least $78 per share, in light of our view of relevant valuation metrics.

We would like to meet with you to provide our perspective on the value of Airgas and are prepared to do so at any time.

On behalf of the Airgas Board of Directors,


John van Roden
