EXHIBIT 10.9.2

                      TAX SETTLEMENT AGREEMENT


     AGREEMENT made May 31, 1994 among Union Carbide Corporation, 
a New York corporation ("Union Carbide") with offices at 39 Old 
Ridgebury Road, Danbury, Connecticut 06817, and Praxair, Inc., a 
Delaware corporation ("Praxair"), with offices at 39 Old Ridgebury 
Road, Danbury, Connecticut 06817, 
                       W I T N E S S E T H:
     WHEREAS, Union Carbide spun-off its industrial gases and 
coatings service businesses to its shareholders on June 30, 1992 
by distributing the shares of Praxair to such shareholders;
     WHEREAS, Union Carbide and Praxair each have a number of tax 
claims and open items relating to the spin-off;
     WHEREAS, Union Carbide and Praxair hereby agree to resolve 
the tax issues as set forth below;
     NOW, THEREFORE, for and in consideration of the mutual 
covenants and agreements hereinafter set forth, the parties hereby 
agree as follows:

     1.  Reference is made to the Tax Disaffiliation Agreement 
dated as of June 4, 1992 between Union Carbide and Praxair 
("TDA").

        (a)  Praxair acknowledges its liability under the TDA and
        agrees to pay Union Carbide $6,495,624 representing


        Praxair's share of federal income taxes for the short
        taxable period January 1, 1992 through June 30, 1992.

        (b)  This is to clarify that Section 1.04 "Business of 
        Gases" includes assets or liabilities transferred to 
        Praxair pursuant to the Transfer Agreement.  In 
        particular, Praxair acknowledges its liability under 
        Section 2.02(a)(v) of the TDA for any sales, use or 
        similar transfer taxes imposed by a taxing 
        jurisdiction in California or any other taxing 
        jurisdiction outside California in connection with the 
        transfer of the assets and liabilities pursuant to the 
        Transfer Agreement.  Capitalized terms used herein 
        without definition shall have the meanings ascribed to 
        them in the TDA.  

        (c)  Pursuant to Section 2.02(a)(i)(A) and Section 
        2.02(a)(ii) of the TDA, Praxair is liable to Union 
        Carbide for any unintentional erroneous exclusion of 
        income for periods prior to July 1, 1992.  Praxair 
        inadvertently omitted income for the year 1991 on the 
        sale of the assets of Linde Gases of the Great Lakes, 
        Inc. and Linde Gases of the Mid-Atlantic, Inc. resulting 
        in additional federal income tax in the amount of 
        $5,607,163.  The TDA does not specifically provide for a 
        payment of a tax audit issue prior to the time of a Final 
        Determination as defined in the TDA.  In order to stop 
        the running of interest on the $5,607,163 owed to Union 
        Carbide, Praxair will pay Union Carbide $5,607,163 plus 
        interest at 7% i.e. $938,036 for a total of $6,545,199 
        (plus $1,241 interest per day for any period after May 
        31, 1994 for which the sum of $6,545,199 remains unpaid).  
        Union Carbide hereby waives and shall hold Praxair 
        harmless for any additional interest (other than interest 
        stated in the preceding sentence) that may otherwise 
        become due under the TDA on the amount of $5,607,163 owed 
        to the Internal Revenue Service for federal income taxes 
        on the sale of Linde Gases of the Great Lakes, Inc. and 
        Linde Gases of the Mid-Atlantic, Inc.  State and local 
        income taxes (and interest and penalties if any,) for 
        which Praxair acknowledges liability to Union Carbide 
        under Section 2.02(a)(ii) of the TDA, shall be computed 
        and paid to Union Carbide at the time of a Final 
        Determination of such liability. For this purpose, a 
        Final Determination will occur when the federal revenue 
        agent's report (RAR) results in a state and local income 
        tax assessment against Union Carbide.  

        (d)  Section 9.01 of the TDA , Deduction for Employee 
        Stock Options, 3rd sentence shall be amended to read as 
        follows:



            "...The amount of the decrease in the cumulative
            income taxes actually paid by a party shall equal
            the difference, if any, between (a) the income tax
            liability of the party determined without regard to
            any deduction claimed or income realized with respect
            to the transfer or exercise of the stock option and 
            (b) the actual income tax liability of the party."

     2.  Reference is made to the Transfer Agreement as defined in 
the TDA.  Although the Transfer Agreement is unclear because 
Praxair is referred to as the "Transferee", Union Carbide 
acknowledges its liability within the spirit of the Transfer 
Agreement for the Stock Exchange Transfer Tax for the transfer of 
Union Carbide Chemicals (Deutschland) GmbH and Union Carbide 
Metals GmbH.  The aggregate tax liability for the transfer of 
shares of both companies is $23,410 which Union Carbide hereby 
agrees to pay Praxair.
     3.  A credit memorandum of $3,400,000 will be issued to 
Praxair by Union Carbide representing the tax accrual for the 8% 
tax imposed on Electric Furnace Products Company (EFP) for 
undistributed profits of S.A. White Martins (SAWM) for which 
Praxair is liable and for which Union Carbide received the 
$3,400,000 tax accrual.  The $3,400,000 credit memorandum is to 
reverse the inadvertent error.  
     4.  Praxair acknowledges liability for and hereby agrees to 
pay Union Carbide $67,000 for Connecticut Sales taxes in 
connection with services provided to Praxair by Union Carbide 
Chemicals and Plastics Company Inc. ("UCC&P") during the period 
July 1, 1992 and September 30, 1993 pursuant to the Bridging 
Services Agreement among Union Carbide, UCC&P, Praxair and Praxair


Surface Technologies Inc.("PST") dated June 4, 1992, the Services 
Agreement between Union Carbide, UCC&P, Praxair and PST dated June 
4, 1992 and the Aviation Services Agreement between Union Carbide 
and Praxair dated June 10, 1992.
     IN WITNESSETH WHEREOF, the parties have executed this 
Agreement as of the date first set forth above.
