EXHIBIT 10.10.2




             FIRST AMENDATORY AGREEMENT TO THE
                EMPLOYEE BENEFITS AGREEMENT   
     This Amendatory Agreement, dated as of May 31, 1994, between 
Union Carbide Corporation ("UCC") and Praxair, Inc. (formerly 
Union Carbide Industrial Gases Inc.) ("Praxair") amends the 
Employee Benefits Agreement between the same parties dated as of 
June 4, 1992 ("Employee Benefits Agreement").  All capitalized 
terms in this Agreement, unless otherwise defined herein, shall 
have the same meaning as set forth in the Employee Benefits 
Agreement.
                    W I T N E S S E T H:
     WHEREAS, UCC and Praxair are parties to the Employee 
Benefits Agreement, which was intended, inter alia, to establish 
a system of payments and reimbursements between the parties with 
respect to employee benefit matters arising out of the spinoff of 
Praxair (formerly a wholly owned subsidiary of UCC) to UCC's 
shareholders; and
     WHEREAS, UCC and Praxair wish to settle the transfer of 
assets between their respective defined benefit plans as provided 
in Paragraph 1 below; and
     WHEREAS, UCC and Praxair desire to revise certain provisions 
of the Employee Benefits Agreement for simplification purposes 
and have determined that the best way to achieve such 
simplification is for each party to give up the right to certain 
payments under the Employee Benefits Agreement in amounts which 
are intended to be, to the extent possible, economically neutral, 
as provided in Paragraphs 2 to 5 below.


     NOW, THEREFORE, in consideration of the mutual premises and 
covenants contained herein, UCC and Praxair agree as follows:
     1.   In final satisfaction of all obligations with respect 
to the transfer of assets between the parties' qualified defined 
benefit plans, Two Million Dollars ($2,000,000.00) shall be 
transferred in cash or securities from the trust for Praxair's 
Retirement Plan to the trust for UCC's Retirement Plan ten days 
after the date of this Agreement.
     2.   With respect to Paragraph 6 of the Employee Benefits 
Agreement:
          (a)  A book reserve is maintained under UCC's 
     retire medical plan for claims incurred but unpaid (as 
     of June 30, 1992).  The Praxair portion (29%) of such 
     reserve is fixed at Three Million Seven Hundred Thousand 
     Dollars ($3,700,000.00).  This amount shall be applied 
     to Praxair's obligations for retiree medical claims.  
     Praxair's obligation to reimburse UCC for retiree 
     medical claims will commence only when such reserve 
     amount has been exhausted.
          (b)  There are reserves at Metropolitan Life for 
     Basic Life Plan claims for deaths before the Spinoff 
     Date and for employees who were disabled before 1986 and 
     die before attaining age 65.  Settlement of these 
     claims shall be entirely for UCC's account.  Thus, UCC 
     will be entitled to the positive or negative experience 
     of such reserves after payment of such claims.  Praxair 
     shall have no responsibility for, or rights in, such 
     reserves and shall have no liability with respect to
     such claims.


          (c)  The Consumer Products reserve credit 
     adjustment, and the value of Kemet reimbursements, for 
     retiree life and medical benefits shall be eliminated 
     from all calculations under the Employee Benefits 
     Agreement.
          (d)  Internal and external administrative costs for 
     retiree life and medical shall be 7.5% of gross claims 
     paid.
          (e)  The value of UCAR reimbursement is eliminated 
     from all calculations under retiree life and medical 
     and, in exchange, Praxair's reimbursement obligations is 
     changed from twenty-nine percent (29%) to twenty-seven 
     and four one-hundredths percent (27.04%).  In keeping 
     with UCC's past practice for charging businesses for 
     expenses before the Spinoff Date, if UCAR defaults on 
     its payment obligation to UCC, and UCC is not otherwise 
     compensated with respect to such default, Praxair's 
     obligation will revert to twenty-nine percent (29%) 
     during the period of any such default.  Should 
     UCC subsequently be reimbursed by UCAR with respect to 
     such defaulted amount, Praxair will share in such 
     reimbursement to the extent necessary to restore it to 
     its 27.04% contribution level.
     3.   Paragraph 8 of the Employee Benefits Agreement is 
expanded to provide that from and after the Spinoff Date, Praxair 
will be entitled to twenty-nine percent (29%) of any recovery, 
whether by successful claim or settlement, made by the UCC 
Retirement Plan arising from events which occurred before the 
Spinoff Date, excluding any recovery in the Aqua Culture


investment which was retained in UCC's Retirement Plan after the 
Spinoff.  The calculation of any such recovery will be net of 
expenses, including legal fees, incurred in pursuing such claims.
     For purposes of Paragraph 8 of the Employee Benefits 
Agreement, the American Typlax settlement is expressly included 
in claims against the UCC Retirement Plan for which Praxair has a 
contribution obligation.

     4.   With respect to Paragraph 22 of the Employee Benefits 
Agreement:
          (a)  The administrative cost of UCC's pension 
     operations is excluded from all calculations of 
     Praxair's reimbursement obligations.
          (b)  Praxair's annual reimbursement obligation for 
     administrative services other than pension operations 
     shall be the lesser of (i) fourteen and one-half percent 
     (14.5%) of UCC's cost, or (ii) one-hundred thousand 
     dollars ($100,000.00).
     5.   All the above provisions are effective as of the 
Spinoff Date, as if included in the Employee Benefits Agreement, 
and any contrary or inconsistent provision in the Employee 
Benefits Agreement is hereby superceded.
     6.   In the event of national health care legislation which 
would substantially change the rights of the parties under the 
Employee Benefits Agreement and this Amendatory Agreement, the 
parties agree to re-negotiate the provisions of this Amendatory 
Agreement to the extent necessary to achieve an equitable 
arrangement which comports with the intent of the Employee 
Benefits Agreement and this Amendatory Agreement.


     7.   All bills rendered and paid to date under the Employee 
Benefits Agreement will be adjusted to comport with this 
Amendatory Agreement.

     8.   The parties believe that Exhibit A hereto is an 
accurate representation of the financial impact of the terms of 
this Amendatory Agreement for the period July 1, 1992 through 
December 31, 1993, but reserve the right to subject to contents 
of such Exhibit A to the review and audit procedures described in 
Paragraph 28 of the Employee Benefits Agreement.
     IN WITNESS WHEREOF, the parties have duly executed and 
entered into this Agreement, as of the date first above written.
