Item 1.01    Entry into a Material Definitive Agreement

     On  October 5,  2004,  CompX  International  Inc.,  a Delaware  corporation
("CompX"),  became eligible to file consolidated returns of federal income taxes
with NL Industries,  Inc., a New Jersey  corporation and a parent corporation of
CompX ("NL"), and Contran Corporation,  a Delaware corporation and the parent of
NL and CompX ("Contran").  Accordingly, CompX, NL and Contran entered into a Tax
Agreement  executed on October 5, 2004 but  effective as of October 1, 2004 (the
"Tax  Agreement").  The  Tax  Agreement  provides  that  NL and  its  qualifying
subsidiaries,  including  CompX,  compute  provisions for U.S. income taxes on a
separate-company basis using the tax elections made by Contran.  Pursuant to the
Tax Sharing  Agreement and using the tax elections  made by Contran,  CompX will
make payments to, or receive  payments from NL, in amounts it would have paid to
or received from the U.S.  Internal  Revenue Service had it not been a member of
NL's  consolidated  tax group but  instead was a separate  taxpayer.  Refunds to
CompX are  generally  limited to amounts  previously  paid under the Tax Sharing
Agreement.

     The  description  of the Tax  Agreement is qualified in its entirety by the
terms  of the  actual  document  filed  as  Exhibit  10.1  to  this  report  and
incorporated herein by reference.
