“Adjusted Treasury Rate” means, with respect, to any redemption date, the sum of (x) either (1) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recent published statistical release designated “H.15 (519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the notes being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounded to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Price for such redemption date, in each case calculated on the third business day preceding the redemption date, and (y) 0.10%.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the redemption date to the maturity date of the notes being redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of notes.

“Comparable Treasury Price” means, with respect to any redemption date, if clause (ii) of the Adjusted Treasury Rate is applicable, the average of four, or such lesser number as is obtained by the indenture trustee, Reference Treasury Dealer Quotations for such redemption date.

“Reference Treasury Dealer” means each of Citigroup Global Markets Inc., HSBC Securities (USA) Inc. and RBS Securities Inc. and their respective successors and assigns, and one other nationally recognized investment banking firm selected by Praxair that is a primary U.S. Government securities dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the indenture trustee, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the indenture trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.
