CHEMICAL COMPANY, the LENDERS party thereto, the DOCUMENTATION AGENTS party
thereto, MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Administrative Agent and
DLJ CAPITAL FUNDING, INC., as Syndication Agent.

     The parties hereto agree as follows:

     Section 1.01.  Defined Terms; References.  Unless otherwise specifically
defined herein, each term used herein which is defined in the Credit Agreement
has the meaning assigned to such term in the Credit Agreement. Each reference to
"hereof", "hereunder", "herein" and "hereby" and each other similar reference
and each reference to "this Agreement" and each other similar reference
contained in the Credit Agreement shall, after this Amendment becomes effective,
refer to the Credit Agreement as amended hereby.

     Section 1.02.  Amendments.

     (a)  The definition of "Adjusted EBITDA" in Section 1.01 is amended to read
in its entirety as follows:

               "ADJUSTED EBITDA" means, for any period, the sum of (i) the
          EBITDA of the Non-JV Group for such period, adjusted to exclude the
          effect of one time charges incurred in connection with (A) the
          Acquisition and subsequent Asset Sales (other than a TDI Sale) in an
          aggregate amount not exceeding $250,000,000 and (B) a TDI Sale, plus
          (ii) the Distributable Cash Flow of all Borrower Joint Ventures and
          non-wholly owned Subject Assets Transferees for such period.

     (b)  The definition of "Excess Cash Flow Prepayment Amount" is amended by
adding at the end thereof, before the period, the following:

          and the aggregate principal amount of the New Senior Notes prepaid
          during such period pursuant to Section 5.15(b)(viii)

     (c)  The following definition is added in alphabetical order to Section
1.01 of the Credit Agreement:
<PAGE>

               "TDI SALE" means an Asset Sale of all or any part of the
          Company's Isocyanates business (including the transfer or assignment
          of the TDI Assets or the TDI Agreements), whether consisting of one
          transaction or more than one related or unrelated transactions.

     (d)  Section 1.02(c) of the Credit Agreement is amended by replacing the
parenthetical "(other than the Acquisition)" in the third sentence of the clause
with the following:

               (other than (i) the Acquisition and (ii) a TDI Sale)

     (e)  Section 2.09 of the Credit Agreement is amended to add at the end of
clause (i) of the first proviso of subsection (a) the phrase "except as provided
in Section 2.09(d)", and Section 2.09 is further amended to add thereto the
following:

               (d) Notwithstanding the foregoing, if the Borrower includes in
          its notice to the Administrative Agent pursuant to Section 2.09(a) of
          its election to prepay any Group of Loans (which for purposes of this
          subsection (d) may include an election to prepay Term Loans-E) that
          the Lenders may reject the prepayment so proposed by the Borrower,
          then the provisions of Section 2.04(e), (f) and (h) shall apply to any
          such offered prepayment, mutatis mutandis, as though the offered
          prepayment were a mandatory prepayment of the Term Loans pursuant to
          Section 2.04(d)(i) or (ii); provided, however, to the extent any
          Lender accepts a prepayment offered pursuant to this subsection (d),
          such prepayment shall be made together with any applicable premium
          specified in Section 2.09(a).

     (f)  Section 5.11 of the Credit Agreement is amended to read in its
entirety as follows:

     SECTION 5.11.  Adjusted Debt to Adjusted EBITDA.  At any date during each
