This Award shall be subject to the clawback or recapture policy, if any, that Praxair may adopt from time to time to the extent provided in such policy and, in accordance with such policy, may be subject to the requirement that this Award be repaid to Praxair after it has been distributed or paid to the Participant.

Tax Withholding. Upon the date of payment of the Award, Praxair will deduct from the number of Shares (or other form of payment, if applicable) otherwise due the Participant, Shares (or other form of payment, if applicable) having a Fair Market Value (or fair market value in the event of payment other than in Shares) sufficient to discharge all applicable federal, state, city, local or foreign taxes of any kind required to be withheld with respect to such payment, provided that, if Shares are so withheld, they shall be withheld only up to the minimum required tax withholding rates or such other rate that will not trigger a negative accounting impact on Praxair.
