Footnotes

F1: In January 2008, the Issuer paid a special dividend of $5.98 per share of common stock to all stockholders of record as of the close of business on December 31, 2007. In connection with these special dividends, the Issuer's Board of Directors adjusted all options that were awarded, but not exercised, prior to the ex-dividend date for each special dividend to account for the effect of each special dividend. The number of shares subject to each such option was increased and the exercise price correspondingly decreased such that each option had the same fair value to the holder before and after giving effect to the payment of each special dividend. Pursuant to this adjustment, the number of shares underlying Mr. Linde's options increased by 7,555 from 121,080 to 128,635 in December 2007 and the per share exercise price was correspondingly decreased.

F2: Represents the weighted average sale price. These shares were sold in multiple transactions at sale prices ranging from $76.7513 to $77.17, inclusive. The reporting person undertakes to provide upon request by the U.S. Securities and Exchange Commission staff, the Issuer, or a security holder of the Issuer, full information regarding the number of shares sold at each separate price.

F3: The option vested in three equal annual installments beginning on January 17, 2003.
