          WHEREAS, the Sellers and the Buyer have previously entered into the

hereunder shall terminate automatically upon (i) the first date on which an
event specified in the definition of Bankruptcy Event occurs as a result of a
case or proceeding being filed against such Seller, (ii) the first date on
which [Crompton Corporation] fails to own and control, directly or indirectly,
(A) in the case of Paratec, less than fifty-one percent (51%) of the voting
interest of such entity, or (B) in the case of all other Sellers not covered
by clause (A), one hundred percent (100%) of the outstanding voting stock of
such entity, (iii) the occurrence of a Termination Event, as defined in the
Receivables Sale Agreement as in effect on the Closing Date, or (iv) in the
case of Paratec, upon not less than five Business Days prior written notice
from the Buyer of its election not to continue to purchase Receivables from
Paratec.  The termination referred to in clauses (i), (ii) and (iv) of the
preceding sentence shall apply only to the relevant Seller and the termination
referred to in clause (iii) shall apply to all Sellers."

SECTION 3. Effectiveness of Agreement. Except as expressly amended by the
terms of this Amendment, all terms and conditions of the Agreement, as
amended, shall remain in full force and effect.

SECTION 4. Execution in Counterparts, Effectiveness.  This Amendment may be
executed by the parties hereto in several counterparts, each of which shall be
executed by the parties hereto and be deemed an original and all of which
shall constitute together but one and the same agreement.

SECTION 5.  Governing Law.  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO CONFLICT OF LAW
PRINCIPLES, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER
