Item
      8.01
Other
      Events
With
respect to a waiver granted on April 29, 2009 by a majority of the lenders
participating in a revolving credit facility of which certain subsidiaries of
Kronos International, Inc., a wholly owned subsidiary of the registrant ("
KII
"), are borrowers (the
"
Borrowers
"), the
registrant hereby incorporates by reference the information set forth under Item
8.01 of the Current Report on Form 8-K that KII (Commission File No.
333-100047) filed with the U.S. Securities and Exchange Commission (the "
SEC
") on May 4,
2009.
The
incorporated information includes forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995.  Any
statement incorporated into this report that is not a statement of historical
fact may be deemed to be a forward-looking statement.  Although the
registrant believes the expectations reflected in such forward-looking
statements are reasonable, it cannot give assurances that these expectations
will prove to be correct.  Such statements by their nature involve
substantial risks and uncertainties that could significantly impact expected
results.  It is not possible to identify all of the risks and
uncertainties the registrant or KII face that could cause actual results to
differ materially from those incorporated into this report.  These
risks and uncertainties include without limitation, the future conditions in the
credit markets, the results of negotiations with the lenders participating in
the credit facility of which certain of KII's subsidiaries are borrowers, the
future liquidity of KII and its affiliates and the significant risk factors set
forth in the registrant's Annual Report on Form 10-K for the fiscal year ended
December 31, 2008 that the registrant filed with the SEC effective March 12,
2009.  Should one or more of these risks materialize (or the
consequences of such a development worsen), or should the underlying assumptions
prove incorrect, actual results could differ materially from those
expected.  The registrant disclaims any intention or obligation to
update or revise any forward-looking statements whether as a result of changes
in information, future events or otherwise.
SIGNATURE
Pursuant
to the requirements of the Securities Exchange Act of 1934, the registrant has
duly caused this report to be signed on its behalf by the undersigned hereunto
