Additional Information

As of December 31, 2014



      The following is a description of the relationships among

the Reporting Person and certain related entities or persons

that may be deemed to beneficially own shares ("Shares") of the

common stock of the issuer, Valhi, Inc. ("Valhi").



      Lisa K. Simmons and Serena Simmons Connelly are daughters

of Harold C. Simmons.  Annette C. Simmons is the widow of Harold

C. Simmons and serves as independent executor of his estate, has

the power to vote and direct the disposition of the Shares held

by the estate and is the designated legatee of such Shares.



      Substantially all of the outstanding voting stock of

Contran Corporation ("Contran") is held by trusts established

for the benefit of Lisa K. Simmons and Serena Simmons Connelly,

daughters of Harold C. Simmons, and their children (the "Family

Trusts"), for which Ms. Lisa Simmons and Ms. Connelly are co-

trustees, or is held directly by Ms. Lisa Simmons and Ms.

Connelly or persons or entities related to them, including their

step-mother Annette C. Simmons, the widow of Harold C. Simmons.

Ms. Annette C. Simmons, Ms. Lisa Simmons and Ms. Connelly also

serve as members of the board of directors of Contran (the

"Contran Board").  Prior to his death on December 28, 2013, Mr.

Simmons served as sole trustee of the Family Trusts.  As co-

trustees of each of the Family Trusts, Ms. Lisa Simmons and Ms.

Connelly have the shared power to vote and direct the

disposition of the shares of Contran stock held by each of the

Family Trusts, and Ms. Lisa Simmons and Ms. Connelly each have

the power to vote and direct the disposition of shares of

Contran stock they hold directly or which is held by other

entities related to them.



      Under a voting agreement (the "Voting Agreement") entered

into effective February 3, 2014 by the voting stockholders of

Contran, and as amended, the size of the Contran Board was

initially fixed at five (5) members; Ms. Lisa Simmons, Ms.

Connelly and Ms. Annette Simmons (and, in the event of their

death, their heirs) each have the right to designate one of the

five members of the Contran Board; and the remaining two members

of the Contran Board must consist of Contran management.

The Voting Agreement terminates in February 2017 (unless Ms.

Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise

mutually agree), and the ability of Ms. Lisa Simmons, Ms.

Connelly, and Ms. Annette Simmons to each designate one member

of the Contran Board is dependent upon each of their continued

beneficial ownership of at least 5% of the combined voting stock

of Contran.  In accordance with such Voting Agreement, each of

Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons have been

designated as members of the Contran Board as of February 3,

2014, along with two members of Contran management.



      Annette C. Simmons is the sole trustee of a trust of

which the beneficiaries are her grandchildren (the

"Grandchildren's Trust"), and she has the power to vote and

direct the disposition of the shares the trust holds.  She

disclaims beneficial ownership of any shares that this trust

holds.

which Ms. Simmons is the sole trustee and the beneficiary (the
