PERFORMANCE SHARE UNIT AWARD UNDER THE 2009 PRAXAIR, INC. LONG TERM INCENTIVE PLAN

Award of Performance Share Units, Performance Measure and Performance Period. The Participant is hereby granted an Award of [___] notional “Performance Share Units” (the “Award”). A Performance Share Unit is a bookkeeping entry which is intended to be equal in value to a single Share. For purposes of this Award, [___] Performance Share Units are considered the Participant’s “Target Amount.” Except as otherwise provided herein, the payment due in settlement of the Participant’s vested Award shall be made in the form of Shares, with the number of Shares payable determined by reference to the Company’s average annual return on capital (“ROC”) for the [___]-year period commencing on [__] and ending on [__] (the “Performance Period”) as set forth below. For purposes of this Award, ROC shall mean the Company’s after-tax return on capital as reported in its quarterly and annual Consolidated Financial Statements and the related Notes, adjusted to eliminate the after-tax effects of any acquisition occurring during the Performance Period; provided, however, that the Committee may, in its sole discretion, disregard such after-tax adjustments related to any acquisition(s) so long as the effect is a reduction of the ROC for the Performance Period. In no event, may the Committee’s exercise of such discretion operate to increase the ROC for the Performance Period.
