NL INDUSTRIES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)


Note 1 - Organization and basis of presentation:

NL Industries, Inc. (NYSE: NL) is a subsidiary of Valhi, Inc. (NYSE: VHI).
At March 31, 2005, Valhi held approximately 83% of NL's outstanding common stock
and Contran Corporation and its subsidiaries held approximately 91% of Valhi's
outstanding common stock. Substantially all of Contran's outstanding voting
stock is held by trusts established for the benefit of certain children and
grandchildren of Harold C. Simmons, of which Mr. Simmons is sole trustee, or is
held by Mr. Simmons or persons or other entities related to Mr. Simmons.
Consequently, Mr. Simmons may be deemed to control each of such companies.

The consolidated balance sheet at March 31, 2005, and the consolidated
statements of income, comprehensive income (loss), stockholders' equity and cash
flows for the interim periods ended March 31, 2004 and 2005, have been prepared
by the Company, without audit, in accordance with accounting principles
generally accepted in the United States of America ("GAAP"). In the opinion of
management, all adjustments, consisting only of normal recurring adjustments,
necessary to state fairly the consolidated financial position, results of
operations and cash flows have been made. See also Note 2.

The results of operations for the interim periods are not necessarily
indicative of the operating results for a full year or of future operations.
Certain information normally included in financial statements prepared in
accordance with GAAP has been condensed or omitted. The accompanying
consolidated financial statements should be read in conjunction with the
Company's Annual Report on Form 10-K for the year ended December 31, 2004, as
filed on March 30, 2005 (the "2004 Annual Report").

On September 24, 2004, the Company completed the acquisition of 10,374,000
shares of CompX International Inc. (NYSE: CIX) common stock, representing
approximately 68% of the outstanding shares of CompX common stock. NL's
acquisition was accounted for under GAAP as a transfer of net assets among
entities under common control, and accordingly resulted in a change in reporting
entity. The Company has retroactively restated its consolidated financial
statements to reflect the consolidation of CompX for all periods presented.

Prior to July 2004, Kronos Worldwide, Inc. (NYSE: KRO) was a majority-owned
subsidiary of the Company. Following the Company's July 2004 dividend in the
form of shares of Kronos common stock distributed to NL shareholders, the
Company's ownership of Kronos was reduced to less than 50%. Consequently,
effective July 1, 2004 the Company ceased to consolidate Kronos' financial
position, results of operations and cash flows and the Company commenced
accounting for its interest in Kronos by the equity method. The Company
continues to report Kronos as a consolidated subsidiary through June 30, 2004,
including the consolidation of Kronos' results of operations and cash flows for
the first quarter of 2004.

As disclosed in the 2004 Annual Report, the Company accounts for
stock-based employee compensation in accordance with Accounting Principles Board
Opinion ("APBO") No. 25, "Accounting for Stock Issued to Employees," and its
various interpretations. See Note 15. Under APBO No. 25, no compensation cost is
generally recognized for fixed stock options in which the exercise price is
greater than or equal to the market price on the grant date. Prior to 2004, and
following the cash settlement of certain stock options held by employees of NL,
the Company commenced accounting for its stock options using the variable
accounting method of APBO No. 25, because NL could not overcome the presumption
that it would not similarly cash settle its remaining stock options. Under the
variable accounting method, the intrinsic value of all unexercised stock options
(including stock options with an exercise price at least equal to the market
price on the date of grant) is accrued as an expense, with subsequent increases
(decreases) in the Company's market price resulting in the recognition of
additional compensation expense (income). Net compensation cost recognized by
the Company in accordance with APBO No. 25 was approximately $1.1 million in the
first quarter of 2004, and net compensation cost recognized by the Company was
not significant in the first quarter of 2005.

The following table presents what the Company's consolidated net income,
and related per share amounts, would have been in the first quarter of 2004 and
2005 if the Company and its subsidiaries and affiliates had each elected to
account for their respective stock-based employee compensation related to stock
options in accordance with the fair value-based recognition provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation," for all awards granted subsequent to January 1, 1995.

Note 2 - December 31, 2004 restated balance sheet:

The consolidated balance sheet of the Company at December 31, 2004 has been
condensed from the Companys audited consolidated fianancial statements at that
date. On May 9, 2005, the Company and its audit committee concluded that the
Company will restate its consolidated financial statements as of December 31,
2004, and for the year then ended, to reflect an additional $4.2 million, or
$.08 per diluted share, noncash income tax benefit in its results of operations
for such year. Such $4.2 million relates to recognition of an additional
deferred income tax benefit related to discontinued operations, to be recognized
in the fourth quarter of 2004. The following table shows (i) the Company's
December 31, 2004 consolidated balance sheet as originally reported, (ii)
adjustments to such consolidated balance sheet to reflect the additional
deferred income tax benefit and (iii) the Company's December 31, 2004
consolidated balance sheet, as restated to reflect the additional deferred
income tax benefit.

Note 3 - Business segment information
% owned at
Business segment Entity March 31, 2005
- --------------------- ------------------------- ----------------

Component products CompX International Inc. 68%
Chemicals Kronos Worldwide, Inc. 36%

The Company's ownership of CompX is held directly by CompX Group, Inc, an
82.4%-owned subsidiary of the Company. An affiliate of Valhi owns the remaining
17.6% of CompX Group. CompX Group's sole asset consists of shares of CompX
common stock representing approximately 83% of the total number of CompX shares
outstanding, and the percentage ownership of CompX shown above represents NL's
ownership interest in CompX Group multiplied by CompX Group's ownership interest
in CompX.

In March 2005, NL paid its $.25 per share regular quarterly dividend in the
form of shares of Kronos common stock in which approximately 266,000 shares, or
approximately .5% of Kronos' outstanding common stock, were distributed to NL
shareholders in the form of a pro-rata dividend. NL's distribution of such
shares of Kronos common stock is taxable to NL, and NL is required to recognize
a taxable gain equal to the difference between the fair market value of the
shares of Kronos common stock distributed and NL's adjusted tax basis in such
stock at the date of distribution. The Company recognized a $3.9 million tax
liability in the first quarter of 2005 related to the Kronos shares distributed.

During the first quarter of 2005, NL also sold approximately 467,000 shares
of Kronos common stock in market transactions for an aggregate of $19.0 million.
The Company recognized a $14.6 million securities transaction gain related to
such sales.

CompX (NYSE: CIX) and Kronos (NYSE: KRO) each file periodic reports with
the Securities and Exchange Commission ("SEC") pursuant to the Securities
Exchange Act of 1934, as amended.

Certain U.S. and non-U.S. tax returns of the Company and Kronos are being
examined and tax authorities have or may propose tax deficiencies, including
penalties and interest. For example:

o NL's and NL's majority-owned subsidiary, NL Environmental Management
Services, Inc. ("EMS"), U.S. federal income tax returns for the years 1998
through 2000 have been audited by the U.S. tax authorities. During the
course of the audit, the IRS proposed a substantial tax deficiency,
including interest, related to a restructuring transaction. To avoid
protracted litigation, minimize the hazards of such litigation and other
considerations, NL and EMS applied to take part in an IRS settlement
initiative applicable to transactions similar to the restructuring
transaction. In April 2003, the IRS notified NL and EMS that they had been
accepted into such settlement initiative. NL has reached an agreement with
the IRS concerning the settlement of this matter pursuant to which, among
other things, the Company paid approximately $21 million, including
interest, up front as a partial payment of the settlement amount (which
amount was paid in April 2005 and is classified as a current liability at
March 31, 2005), and NL will be required to recognize the remaining
settlement amount (approximately $15 million) ratably over a 15-year time
period beginning in 2004. NL and the IRS have signed the settlement
agreement, and the case is now closed.

o Kronos has received a preliminary tax assessment related to 1993 from the
Belgian tax authorities proposing tax deficiencies, including related
interest, of approximately euro 6 million ($8 million at March 31, 2005).
Kronos has filed a protest to this assessment, and believes that a
significant portion of the assessment is without merit. The Belgian tax
authorities have filed a lien on the fixed assets of Kronos' Belgian TiO2
operations in connection with this assessment. In April 2003, Kronos
received a notification from the Belgian tax authorities of their intent to
assess a tax deficiency related to 1999 that, including interest, is
expected to be approximately euro 9 million ($12 million). Kronos believes
the proposed assessment is substantially without merit, and Kronos has
filed a written response.

o The Norwegian tax authorities have notified Kronos of their intent to
assess tax deficiencies of approximately kroner 12 million ($2 million)
relating to the years 1998 through 2000. Kronos has objected to this
proposed assessment.

o Kronos has received a preliminary tax assessment from the Canadian tax
authorities related to the years 1998 and 1999 proposing tax deficiencies
of Cdn. $11 million ($9 million). Kronos has filed a protest and believes a
significant portion of the assessment is without merit.

No assurance can be given that these unresolved tax matters will be
resolved in the Company's favor in view of the inherent uncertainties involved
in settlement initiatives, court and tax proceedings. The Company believes that
it has provided adequate accruals for additional taxes and related interest
expense which may ultimately result from all such examinations and believes that
the ultimate disposition of such examinations should not have a material adverse
effect on its consolidated financial position, results of operations or
liquidity.

Note 13 - Commitments and contingencies:

Lead pigment litigation. The Company's former operations included the
manufacture of lead pigments for use in paint and lead-based paint. NL, other
former manufacturers of lead pigments for use in paint, and lead-based paint,
and the Lead Industries Association (which discontinued business operations in
2002) have been named as defendants in various legal proceedings seeking damages
for personal injury, property damage and governmental expenditures allegedly
caused by the use of lead-based paints. Certain of these actions have been filed
by or on behalf of states, large U.S. cities or their public housing authorities
and school districts, and certain others have been asserted as class actions.
These lawsuits seek recovery under a variety of theories, including public and
private nuisance, negligent product design, negligent failure to warn, strict
liability, breach of warranty, conspiracy/concert of action, aiding and
abetting, enterprise liability, market share liability, intentional tort, fraud
and misrepresentation, violations of state consumer protection statutes,
supplier negligence and similar claims.

The plaintiffs in these actions generally seek to impose on the defendants
responsibility for lead paint abatement and health concerns associated with the
use of lead-based paints, including damages for personal injury, contribution
and/or indemnification for medical expenses, medical monitoring expenses and
costs for educational programs. A number of cases are inactive or have been
dismissed or withdrawn. Most of the remaining cases are in various pre-trial
stages. Some are on appeal following dismissal or summary judgment rulings in
favor of the defendants. In addition, various other cases are pending (in which
the Company is not a defendant) seeking recovery for injury allegedly caused by
lead pigment and lead-based paint. Although the Company is not a defendant in
these cases, the outcome of these cases may have an impact on additional cases
being filed against the Company in the future.

The Company believes these actions are without merit, intends to continue
to deny all allegations of wrongdoing and liability and to defend against all
actions vigorously. The Company has neither lost nor settled any of these cases.
The Company has not accrued any amounts for the pending lead pigment and
lead-based paint litigation. Liability that may result, if any, cannot
reasonably be estimated. There can be no assurance that the Company will not
incur liability in the future in respect of this pending litigation in view of
the inherent uncertainties involved in court and jury rulings in pending and
possible future cases. If any such future liability were to be incurred, it
could be material to the Company's consolidated financial statements, results of
operations and liquidity.

NL previously filed an action against certain of its former insurance
carriers for coverage with respect to defense costs related to certain specific
lead pigment litigation matters. This action was settled in 2000. The Company is
continuing discussions with certain former insurance carriers for coverage with
respect to defense costs related to the Company's remaining past and present
lead pigment litigation matters. Whether insurance coverage for defense costs
will be found to exist for lead pigment litigation depends on a variety of
factors, and there can be no assurance that the Company will be successful in
obtaining reimbursement for past or future defense costs incurred. The Company
has not considered any potential insurance recoveries for lead pigment
litigation in determining related accruals.

Environmental matters and litigation. The Company's operations are governed
by various environmental laws and regulations. Certain of the Company's
businesses are and have been engaged in the handling, manufacture or use of
substances or compounds that may be considered toxic or hazardous within the
meaning of applicable environmental laws. As with other companies engaged in
similar businesses, certain past and current operations and products of the
Company have the potential to cause environmental or other damage. The Company
has implemented and continues to implement various policies and programs in an
effort to minimize these risks. The Company's policy is to maintain compliance
with applicable environmental laws and regulations at all of its plants and to
strive to improve environmental performance. From time to time, the Company may
be subject to environmental regulatory enforcement under U.S. and foreign
statutes, resolution of which typically involves the establishment of compliance
programs. It is possible that future developments, such as stricter requirements
of environmental laws and enforcement policies thereunder, could adversely
affect the Company's production, handling, use, storage, transportation, sale or
disposal of such substances. The Company believes all of its plants are in
substantial compliance with applicable environmental laws.

Certain properties and facilities used in the Company's former businesses,
including divested primary and secondary lead smelters and former mining
locations of NL, are the subject of civil litigation, administrative proceedings
or investigations arising under federal and state environmental laws.
Additionally, in connection with past disposal practices, the Company has been
named as a defendant, potential responsible party ("PRP") or both, pursuant to
the Comprehensive Environmental Response, Compensation and Liability Act, as
amended by the Superfund Amendments and Reauthorization Act ("CERCLA") and
similar state laws in various governmental and private actions associated with
waste disposal sites, mining locations, and facilities currently or previously
owned, operated or used by the Company or its subsidiaries, or their
predecessors, certain of which are on the U.S. EPA's Superfund National
Priorities List or similar state lists. These proceedings seek cleanup costs,
damages for personal injury or property damage and/or damages for injury to
natural resources. Certain of these proceedings involve claims for substantial
amounts. Although the Company may be jointly and severally liable for such
costs, in most cases it is only one of a number of PRPs who may also be jointly
and severally liable.

Environmental obligations are difficult to assess and estimate for numerous
reasons including the complexity and differing interpretations of governmental
regulations, the number of PRPs and the PRPs' ability or willingness to fund
such allocation of costs, their financial capabilities and the allocation of
costs among PRPs, the solvency of other PRPs, the multiplicity of possible
solutions, and the years of investigatory, remedial and monitoring activity
required. In addition, the imposition of more stringent standards or
requirements under environmental laws or regulations, new developments or
changes respecting site cleanup costs or allocation of such costs among PRPs,
solvency of other PRPs, the results of future testing and analysis undertaken
with respect to certain sites or a determination that the Company is potentially
responsible for the release of hazardous substances at other sites, could result
in expenditures in excess of amounts currently estimated by the Company to be
required for such matters. In addition, with respect to other PRPs and the fact
that the Company may be jointly and severally liable for the total remediation
cost at certain sites, the Company could ultimately be liable for amounts in
excess of its accruals due to, among other things, reallocation of costs among
PRPs or the insolvency of one or more PRPs. No assurance can be given that
actual costs will not exceed accrued amounts or the upper end of the range for
sites for which estimates have been made and no assurance can be given that
costs will not be incurred with respect to sites as to which no estimate
presently can be made. Further, there can be no assurance that additional
environmental matters will not arise in the future. If any such future liability
were to be incurred, it could be material to the Company's consolidated
financial statements, results of operations and liquidity.

The Company records liabilities related to environmental remediation
obligations when estimated future expenditures are probable and reasonably
estimable. Such accruals are adjusted as further information becomes available
or circumstances change. Estimated future expenditures are generally not
discounted to their present value. Recoveries of remediation costs from other
parties, if any, are recognized as assets when their receipt is deemed probable.
At March 31, 2005, no receivables for recoveries had been recognized.

The exact time frame over which the Company makes payments with respect to
its accrued environmental costs is unknown and is dependent upon, among other
things, the timing of the actual remediation process which in part depends on
factors outside the control of the Company. At each balance sheet date, the
Company makes an estimate of the amount of its accrued environmental costs which
will be paid out over the subsequent 12 months, and the Company classifies such
amount as a current liability. The remainder of the accrued environmental costs
is classified as a noncurrent liability.

A summary of the activity in the Company's accrued environmental costs
during the first quarter of 2005 is presented in the table below.

Amount

On a quarterly basis, the Company evaluates the potential range of its
liability at sites where it has been named as a PRP or defendant, including
sites for which EMS has contractually assumed the Company's obligation. At March
31, 2005, the Company had accrued $66.8 million for those environmental matters
which the Company believes are reasonably estimable. The Company believes it is
not possible to estimate the range of costs for certain sites. The upper end of
the range of reasonably possible costs to the Company for sites for which the
Company believes it is possible to estimate costs is approximately $91 million.
The Company's estimates of such liabilities have not been discounted to present
value.

At March 31, 2005, there are approximately 20 sites for which the Company
is unable to estimate a range of costs. For these sites, generally the
investigation is in the early stages, and it is either unknown as to whether or
not the Company actually had any association with the site, or if the Company
had association with the site, the nature of its responsibility, if any, for the
contamination at the site and the extent of contamination. The timing on when
information would become available to the Company to allow the Company to
estimate a range of loss is unknown and dependent on events outside the control
of the Company, such as when the party alleging liability provides information
to the Company.

At March 31, 2005, the Company had $14 million in restricted cash,
restricted cash equivalents and restricted marketable debt securities held by
special purpose trusts, the assets of which can only be used to pay for certain
of the Company's future environmental remediation and other environmental
expenditures (December 31, 2004 - $19 million). Use of such restricted balances
does not affect the Company's consolidated net cash flows.

Other litigation. Reference is made to the 2004 Annual Report for a
discussion of certain other legal proceedings to which the Company is a party.

NL has been named as a defendant in various lawsuits in a variety of
jurisdictions, alleging personal injuries as a result of occupational exposure
primarily to products manufactured by formerly-owned operations of NL containing
asbestos, silica and/or mixed dust. Approximately 500 of these types of cases
involving a total of approximately 22,000 plaintiffs and their spouses remain
pending. Of these plaintiffs, approximately 4,700 are represented by five cases
pending in Mississippi state courts and approximately 5,000 are represented by
three cases that have been removed to federal court in Mississippi, where they
have been, or are in the process of being, transferred to the multi-district
litigation pending in the United States District Court for the Eastern District
of Pennsylvania. NL has not accrued any amounts for this litigation because
liability that might result to NL, if any, cannot be reasonably estimated. In
addition, from time to time, NL has received notices regarding asbestos or
silica claims purporting to be brought against former subsidiaries of NL,
including notices provided to insurers with which NL has entered into
settlements extinguishing certain insurance policies. These insurers may seek
indemnification from NL.

In addition to the litigation described above, the Company and its
affiliates are also involved in various other environmental, contractual,
product liability, patent (or intellectual property), employment and other
claims and disputes incidental to its present and former businesses. In certain
cases, the Company has insurance coverage for such items; however the Company
does not currently expect additional material insurance coverage for
environmental claims. The Company currently believes that the disposition of all
claims and disputes, individually or in the aggregate, should not have a
material adverse effect on its consolidated financial position, results of
operations or liquidity.

Note 14 - Discontinued operations:

As discussed in the 2004 Annual Report, in December 2004 CompX's board of
directors committed to a formal plan to dispose of its Thomas Regout operations
in the Netherlands. Such operations, which previously were included in the
Company's component products operating segment (see Note 3), met all of the
criteria under GAAP to be classified as an asset held for sale at December 31,
2004, and accordingly the results of operations of Thomas Regout have been
classified as discontinued operations for all periods presented. The Company has
not reclassified its consolidated balance sheets or statements of cash flows. In
classifying the net assets of the Thomas Regout operations as an asset held for
sale, the Company concluded that the carrying amount of the net assets of such
operations exceeded the estimated fair value less costs to sell of such
operations, and accordingly in the fourth quarter of 2004 the Company recognized
a $6.5 million impairment charge to write-down its investment in the Thomas
Regout operations to its estimated net realizable value. Such charge represented
an impairment of goodwill.

In January 2005, CompX completed the sale of such operations for proceeds
(net of expenses) of approximately $22.3 million. The net proceeds consisted of
approximately $18.1 million in cash at the date of sale and a $4.2 million
principal amount note receivable from the purchaser bearing interest at a fixed
rate of 7% and payable over four years. The note receivable is collateralized by
a secondary lien on the assets sold and is subordinated to certain third-party
indebtedness of the purchaser. Accordingly, the Company no longer includes the
results of operations of Thomas Regout subsequent to December 31, 2004 in its
consolidated financial statements. The net proceeds from the January 2005 sale
of Thomas Regout were approximately $860,000 less than the net realizable value
estimated at the time of the goodwill impairment charge (primarily due to higher
expenses associated with the disposal of the Thomas Regout operations), and
discontinued operations in the first quarter of 2005 includes a charge related
to such differential ($326,000 loss, net of income tax benefit and minority
interest). During the first quarter of 2004, the Thomas Regout operations
reported net sales of $9.9 million, operating income of $400,000, interest
expense of $400,000 and a nominal amount of net income.

Note 15 - Accounting principles not yet implemented:

Inventory costs. The Company will adopt SFAS No. 151, "Inventory Costs, an
amendment of ARB No. 43, Chapter 4," for inventory costs incurred on or after
January 1, 2006. SFAS No. 151 requires that the allocation of fixed production
overhead costs to inventory shall be based on normal capacity. Normal capacity
is not defined as a fixed amount; rather, normal capacity refers to a range of
production levels expected to be achieved over a number of periods under normal
circumstances, taking into account the loss of capacity resulting from planned
maintenance shutdowns. The amount of fixed overhead allocated to each unit of
production is not increased as a consequence of idle plant or production levels
below the low end of normal capacity, but instead a portion of fixed overhead
costs is charged to expense as incurred. Alternatively, in periods of production
above the high end of normal capacity, the amount of fixed overhead costs
allocated to each unit of production is decreased so that inventories are not
measured above cost. SFAS No. 151 also clarifies existing GAAP to require that
abnormal freight and wasted materials (spoilage) are to be expensed as incurred.
The Company believes its production cost accounting already complies with the
requirements of SFAS No. 151, and the Company does not expect adoption of SFAS
No. 151 will have a material effect on its consolidated financial statements.

Stock options. As permitted by regulations of the Securities and Exchange
Commission ("SEC") the Company will adopt SFAS No. 123R, "Share-Based Payment,"
as of January 1, 2006. SFAS No. 123R, among other things, eliminates the
alternative in existing GAAP to use the intrinsic value method of accounting for
stock-based employee compensation under APBO No. 25. Upon adoption of SFAS No.
123R, the Company will generally be required to recognize the cost of employee
services received in exchange for an award of equity instruments based on the
grant-date fair value of the award, with the cost recognized over the period
during which an employee is required to provide services in exchange for the
award (generally, if the vesting period of the award). No compensation cost will
be recognized in the aggregate for equity instruments for which the employee
does not render the requisite service (generally, the instrument is forfeited
before it has vested). The grant-date fair value will be estimated using
option-pricing models (e.g. Black-Scholes or a lattice model). Under the
transition alternatives permitted under SFAS No. 123R, the Company will apply
the new standard to all new awards granted on or after January 1, 2006, and to
all awards existing as of December 31, 2005 which are subsequently modified,
repurchased or cancelled. Additionally, as of January 1, 2006, the Company will
be required to recognize compensation cost for the portion of any non-vested
award existing as of December 31, 2005 over the remaining vesting period.
Because the number of non-vested awards as of December 31, 2005 with respect to
options granted by NL is not expected to be material, the effect of adopting
SFAS No. 123R is not expected to be significant in so far as it relates to
existing stock options. Should NL or its subsidiaries and affiliates, however,
either grant a significant number of options or modify, repurchase or cancel
existing options in the future, the effect on the Company's consolidated
financial statements could be material.

Impairment of investments. In June 2004, the Emerging Issues Task Force
("EITF") issued EITF No. 03-01, The Meaning of Other-Than-Temporary Impairment
and Its Application to Certain Investments. EITF No. 03-01, the effective date
of which is still pending based upon a deferral granted by the Financial
Accounting Standards Board, provides guidance for determining when an investment
covered by its scope is considered impaired, whether any impairment is other
than temporary and the date when an impairment loss is to be recognized. The
Company does not currently expect compliance with EITF No. 03-01 will have a
material affect on its consolidated financial statements, whenever it becomes
effective.

Note 16 - Investment in Kronos:

At March 31, 2005, the Company held 17.5 million shares of Kronos with a
quoted market price of $42.51 per share, or an aggregate market value of $745
million.

At March 31, 2005, Kronos reported total assets of $1.3 billion and
stockholder's equity of $482.3 million. Kronos' total assets at March 31, 2005
include current assets of $502.1 million, net property and equipment of $441.8
million and an investment in a TiO2 manufacturing joint venture of $121.1
million. Kronos' total liabilities at March 31, 2005 include current liabilities
of $213.7 million, long-term debt of $493.1 million, accrued OPEB and pension
costs aggregating $68.1 million and deferred income taxes of $58.9 million.

During the three months ended March 31, 2005, Kronos reported net sales of
$291.9 million, income from operations of $46.4 million and net income of $21.4
million.



ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

- -------------------------------------------------------------------------------
RESULTS OF OPERATIONS:

General

The Company reported net income of $13.2 million, or $.27 per diluted
share, in the first quarter of 2005 compared to income of $5.1 million, or $.11
per diluted share, in the first quarter of 2004.

The increase in the Company's diluted earnings per share from the first
quarter of 2004 compared to the first quarter of 2005 is due primarily to the
net effects of (i) higher component products segment profit, (ii) higher
earnings attributable to Kronos and (iii) security transactions gains from the
sale of shares of Kronos common stock. The Company currently believes its net
income in 2005 will be lower than 2004 due primarily to the effect of certain
income tax benefits recognized primarily in the second quarter of 2004.

As discussed in Note 1 to the Consolidated Financial Statements, on
September 24, 2004, the Company purchased 10,374,000 shares of CompX common
stock, representing approximately 68% of the outstanding shares of CompX common
stock, from Valhi and a wholly-owned subsidiary of Valhi. Because Valhi, NL and
CompX are all entities under the common control of Contran, the Company's
acquisition of the shares of CompX common stock results in a change in reporting
entity and the Company has retroactively restated its consolidated financial
statements to reflect the consolidation of CompX for all periods presented.

Also discussed in Note 1, prior to July 2004, Kronos was a majority-owned
subsidiary of the Company. Following the Company's July 2004 dividend in the
form of shares of Kronos common stock distributed to NL shareholders, the
Company's ownership of Kronos was reduced to less than 50%. Consequently,
effective July 1, 2004 the Company ceased to consolidate Kronos' financial
position, results of operations and cash flows and the Company commenced
accounting for its interest in Kronos by the equity method. The Company
continues to report Kronos as a consolidated subsidiary through June 30, 2004,
including the consolidation of Kronos' results of operations and cash flows for
the first quarter of 2004.

As provided by the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, the Company cautions that the statements in this
Quarterly Report on Form 10-Q relating to matters that are not historical facts,
are forward-looking statements that represent management's beliefs and
assumptions based on currently available information. Forward-looking statements
can be identified by the use of words such as "believes," "intends," "may,"
"should," "could," "anticipates," "expected" or comparable terminology, or by
discussions of strategies or trends. Although the Company believes that the
expectations reflected in such forward-looking statements are reasonable, it
cannot give any 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, and actual future results could
differ materially from those described in such forward-looking statements. While
it is not possible to identify all factors, the Company continues to face many
risks and uncertainties. The factors that could cause actual future results to
differ materially from those described herein are the risks and uncertainties
discussed in this Quarterly Report and those described from time to time in the
Company's other filings with the SEC include, but are not limited to, the
following:

o Future supply and demand for the Company's products,
o The extent of the dependence of certain of the Company's businesses on
certain market sectors,
o The cyclicality of the Company's businesses (such as Kronos' TiO2
operations),
o Customer inventory levels (such as the extent to which Kronos' customers
may, from time to time, accelerate purchases of TiO2 in advance of
anticipated price increases or defer purchases of TiO2 in advance of
anticipated price decreases),
o Changes in raw material and other operating costs (such as energy and steel
costs),
o The possibility of labor disruptions,
o General global economic and political conditions (such as changes in the
level of gross domestic product in various regions of the world and the
impact of such changes on demand for TiO2 and component products),
o Demand for office furniture,
o Competitive products and substitute products, including increased
competition from low-cost manufacturing sources (such as China),
o Customer and competitor strategies,
o The impact of pricing and production decisions,
o Competitive technology positions,
o Service industry employment levels,
o Fluctuations in currency exchange rates (such as changes in the exchange
rate between the U.S. dollar and each of the euro, the Norwegian kroner,

o Operating interruptions (including, but not limited to, labor disputes,

o The ability of the Company to renew or refinance credit facilities,
o The ultimate outcome of income tax audits, tax settlement initiatives or
other tax matters,
o The introduction of trade barriers,
o Potential difficulties in integrating completed or future acquisitions,

business,
o Uncertainties associated with new product development,
o The ultimate ability to utilize income tax attributes, the benefit of which
has been recognized under the "more-likely-than-not" recognition criteria,

changes in government regulations which might impose various obligations on
present and former manufacturers of lead pigment and lead-based paint,
including NL, with respect to asserted health concerns associated with the
use of such products),
o The ultimate resolution of pending litigation (such as NL's lead pigment
litigation and litigation surrounding environmental matters), and
o Possible future litigation.

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 forecasted or expected. The
Company disclaims any intention or obligation to update or revise any
forward-looking statement whether as a result of changes in information, future
events or otherwise.

(In millions)

Net sales $ 43.5 $ 46.8 +8%
Segment profit 2.5 4.2 +68%

Component products sales were higher in the first quarter of 2005 as
compared to the first quarter of 2004 due primarily to an increase in sales
volume and selling prices for certain of CompX's precision slide and ergonomic
products. During the first quarter of 2005, sales of slide and ergonomic
products increased 16% and 10%, respectively, as compared to the first quarter
of 2004, while sales of security products decreased 1%. The percentage changes
in both slide and ergonomic products include the impact resulting from changes
in foreign currency exchange rates. Sales of security products are generally
denominated in U.S. dollars.

Component products operating income comparisons in 2005 were favorably
impacted by the effect of certain cost reduction initiatives previously
undertaken. Component products operating income comparisons were also impacted
by the net effects of increases in the cost of steel (the primary raw material
for CompX's products) and a favorable change in product mix for security
products.

CompX has substantial operations and assets located outside the United
States in Canada and Taiwan. A portion of CompX's sales generated from its
non-U.S. operations are denominated in currencies other than the U.S. dollar,
principally the Canadian dollar and the New Taiwan dollar. In addition, a
portion of CompX's sales generated from its non-U.S. operations (principally in
Canada) are denominated in the U.S. dollar. Most raw materials, labor and other
production costs for such non-U.S. operations are denominated primarily in local
currencies. Consequently, the translated U.S. dollar values of CompX's foreign
sales and operating results are subject to currency exchange rate fluctuations
which may favorably or unfavorably impact reported earnings and may affect
comparability of period-to-period operating results. During the first quarter of
2005, currency exchange rate fluctuations positively impacted component products
sales comparisons with the same period in 2004, while currency exchange rate
fluctuations did not significantly impact component products segment profit
comparisons for the same periods.

While demand has stabilized across most product segments, certain customers
are seeking lower cost Asian sources as alternatives to CompX's products. CompX
believes the impact of this will be mitigated through ongoing initiatives to
expand both new products and new market opportunities. Asian sourced competitive
pricing pressures are expected to continue to be a challenge as Asian
manufacturers, particularly those located in China, gain market share. CompX's
strategy in responding to the competitive pricing pressure has included reducing
production cost through product reengineering, improvement in manufacturing
processes or moving production to lower-cost facilities, including CompX's own
Asian based manufacturing facilities. CompX also has emphasized and focused on
opportunities where it can provide value-added customer support services that
Asian based manufacturers are generally unable to provide. The combination of
CompX's cost control initiatives together with its value-added approach to
development and marketing of products are believed to help mitigate the impact
of competitive pricing pressures.

Additionally, CompX's cost for steel continues to be unstable due to the
continued high demand and shortages in various parts of the world. While CompX
has thus far been able to pass a majority of its higher raw material costs on to
its customers through price increases and surcharges, there is no assurance that
CompX would be able to continue to pass along any additional higher costs to its
customers. The price increases and surcharges may accelerate the efforts of some
of CompX's customers to find less expensive products from foreign manufacturers.
CompX will continue to focus on cost improvement initiatives, utilizing lean
manufacturing techniques and prudent balance sheet management in order to
minimize the impact of lower sales, particularly to the office furniture
industry, and to develop value-added customer relationships with an additional
focus on sales of CompX's higher-margin ergonomic computer support systems to
improve operating results. These actions, along with other activities to
eliminate excess capacity, are designed to position CompX to expand more
effectively on both new product and new market opportunities to improve CompX'
profitability.

Chemicals

Relative changes in Kronos' TiO2 sales and operating income during the 2004
and 2005 periods presented are primarily due to (i) relative changes in TiO2
average selling prices and (ii) relative changes in foreign currency exchange
rates. Selling prices (in billing currencies) for TiO2, Kronos' principal
product, were generally: decreasing during the first half of 2004 and increasing
in the last half of 2004 and the first quarter of 2005.

_______________________________

* Thousands of metric tons

Kronos' sales increased $28.6 million (11%) in the first quarter of 2005
compared to the first quarter of 2004 due to the net effects of higher average
TiO2 selling prices, lower TiO2 selling volumes and the favorable effect of
fluctuations in foreign currency exchange rates, which increased chemicals sales
by approximately $11 million, as further discussed below. Excluding the effect
of fluctuations in the value of the U.S. dollar relative to other currencies,
Kronos' average TiO2 selling prices in billing currencies in the first quarter
of 2005 were 8% higher as compared to the first quarter of 2004. When translated
from billing currencies to U.S. dollars using actual foreign currency exchange
rates prevailing during the respective periods, Kronos' average TiO2 selling
prices in the first quarter of 2005 increased 13% compared to the first quarter
of 2004.

Kronos' sales are denominated in various currencies, including the U.S.
dollar, the euro, other major European currencies and the Canadian dollar. The
disclosure of the percentage change in Kronos' average TiO2 selling prices in
billing currencies (which excludes the effects of fluctuations in the value of
the U.S. dollar relative to other currencies) is considered a "non-GAAP"
financial measure under regulations of the SEC. The disclosure of the percentage
change in Kronos' average TiO2 selling prices using actual foreign currency
exchange rates prevailing during the respective periods is considered the most
directly comparable financial measure presented in accordance with GAAP ("GAAP
measure"). Kronos discloses percentage changes in its average TiO2 prices in
billing currencies because Kronos believes such disclosure provides useful
information to investors to allow them to analyze such changes without the
impact of changes in foreign currency exchange rates, thereby facilitating
period-to-period comparisons of the relative changes in average selling prices
in the actual various billing currencies. Generally, when the U.S. dollar either
strengthens or weakens against other currencies, the percentage change in
average selling prices in billing currencies will be higher or lower,
respectively, than such percentage changes would be using actual exchange rates
prevailing during the respective periods. The difference between the 13%
increase in Kronos' average TiO2 selling prices during the first quarter of 2005
as compared to the first quarter of 2004 using actual foreign currency exchange
rates prevailing during the respective periods (the GAAP measure), and the 8%
increase in Kronos' average TiO2 selling prices in billing currencies (the
non-GAAP measure) during such periods is due to the effect of changes in foreign
currency exchange rates. The above table presents in a tabular format (i) the
percentage change in Kronos' average TiO2 selling prices using actual foreign
currency exchange rates prevailing during the respective periods (the GAAP
measure), (ii) the percentage change in Kronos' average TiO2 selling prices in
billing currencies (the non-GAAP measure) and (iii) the percentage change due to
changes in foreign currency exchange rates (or the reconciling item between the
non-GAAP measure and the GAAP measure).

Kronos' TiO2 sales volumes in the first quarter of 2005 decreased 3%
compared to the first quarter of 2004, due primarily to lower volumes in export
markets. Demand for TiO2 has remained strong throughout 2004 and 2005, and while
Kronos believes that the strong demand is largely attributable to the end-use
demand of its customers, it is possible that some portion of the strong demand
resulted from customers increasing their inventory levels of TiO2 in advance of
implementation of announced or anticipated price increases. Kronos' operating
income comparisons were also favorably impacted by higher production levels,
which increased 4% in the first quarter of 2005 as compared to the same period
in 2004. Kronos' operating rates were near full capacity in both periods, and
Kronos' production volume in the first quarter of 2005 was a new record for
Kronos for a first quarter.

Kronos has substantial operations and assets located outside the United
States (primarily in Germany, Belgium, Norway and Canada). A significant amount
of Kronos' sales generated from its non-U.S. operations are denominated in
currencies other than the U.S. dollar, principally the euro, other major
European currencies and the Canadian dollar. A portion of Kronos' sales
generated from its non-U.S. operations are denominated in the U.S. dollar.
Certain raw materials, primarily titanium-containing feedstocks, are purchased
in U.S. dollars, while labor and other production costs are denominated
primarily in local currencies. Consequently, the translated U.S. dollar value of
Kronos' foreign sales and operating results are subject to currency exchange
rate fluctuations which may favorably or adversely impact reported earnings and
may affect the comparability of period-to-period operating results. Overall,
fluctuations in the value of the U.S. dollar relative to other currencies,
primarily the euro, increased TiO2 sales by a net $11 million in the first
quarter of 2005 as compared to the first quarter of 2004. Fluctuations in the
value of the U.S. dollar relative to other currencies similarly impacted Kronos'
foreign currency-denominated operating expenses. Kronos' operating costs that
are not denominated in the U.S. dollar, when translated into U.S. dollars, were
higher in the first quarter of 2005 as compared to the same period in 2004.
Overall, currency exchange rate fluctuations resulted in a net $1 million
increase in Kronos' segment profit in the first quarter of 2005 as compared to
the first quarter of 2004.

Reflecting the continued implementation of price increase announcements,
Kronos' average TiO2 selling prices in billing currencies in the first quarter
of 2005 were 4% higher than the fourth quarter of 2004. Kronos expects its TiO2
production volumes in the remainder of 2005 will be slightly higher than its
2004 volumes, with sales volumes comparable to or slightly lower in 2005 as
compared to 2004. Kronos' average TiO2 selling prices, which started to increase
during the second half of 2004 and continued to increase during the first
quarter of 2005, are expected to continue to increase during the remainder of
2005, and consequently, Kronos currently expects its average TiO2 selling
prices, in billing currencies, will be higher in 2005 as compared to 2004. The
anticipated higher selling prices in 2005 reflect the expected continued
implementation of selling price announcements, including Kronos' latest price
increases announced in March 2005. The extent to which all of such price
increases, and any additional price increases which may be announced
subsequently in 2005, will be realized will depend on, among other things,
economic factors. Overall, Kronos expects its chemicals segment profit in 2005
will be higher than 2004, due primarily to higher expected selling prices.
Kronos' expectations as to the future prospects of Kronos and the TiO2 industry
are based upon a number of factors beyond Kronos' control, including worldwide
growth of gross domestic product, competition in the marketplace, unexpected or
earlier-than-expected capacity additions and technological advances. If actual
developments differ from Kronos' expectations, Kronos' results of operations
could be unfavorably affected.

Kronos' efforts to debottleneck its production facilities to meet long-term
demand continues to prove successful. Such debottlenecking efforts included,
among other things, the addition of back-end finishing capacity to be able to
process a larger quantity of the base TiO2 produced and equipment upgrades and
enhancements to allow for reduced downtime for maintenance activities. Kronos'
production capacity has increased by approximately 30% over the past ten years
due to debottlenecking programs, with only moderate capital expenditures. Kronos
believes its annual attainable production capacity for 2005 is approximately
500,000 metric tons, with some slight additional capacity available in 2006
through its continued debottlenecking efforts.

See the preceding discussion relating to Kronos' segment profit for the

relates principally to Kronos International, Inc.'s ("KII") Senior Secured
Notes.

General corporate items

Securities transactions, net in the first quarter of 2005 relate
principally to a $14.6 million gain ($7.9 million, or $.16 per diluted share,
net of income taxes) related to NL's sale of approximately 467,000 shares of
Kronos common stock in market transactions. See Note 3 to the Consolidated
Financial Statements.

Substantially all of the interest expense in the first quarter of 2004
relates to Kronos. Interest expense related to CompX declined by approximately
$100,000 in the first quarter of 2005 compared to 2004 due primarily to lower
average levels of outstanding debt. CompX expects interest expense will continue
to be lower during the remainder of 2005 as compared to the last three quarters
of 2004 due to lower average levels of outstanding debt.

Net general corporate expenses in the first quarter of 2005 were lower than
the same period of 2004 due primarily to lower environmental remediation and
legal expenses of NL. Net general corporate expenses in calendar 2005 are
currently expected to be higher than 2004, primarily due to higher expected
legal expenses of NL resulting from an increase in litigation and related
expenses. However, obligations for environmental remediation are difficult to
assess and estimate and no assurance can be given that actual costs will not
exceed accrued amounts or that costs will not be incurred with respect to sites
for which no estimate of liability can presently be made. See Note 13 to the
Consolidated Financial Statements.

Provision for income taxes

The principal reasons for the difference between the Company's effective
income tax rate and the U.S. federal statutory income tax rates are explained in
Note 11 to the Consolidated Financial Statements.

Minority interest

See Note 10 to the Consolidated Financial Statements.

Minority interest in NL's subsidiaries includes the Company's
majority-owned environmental management subsidiary, EMS. EMS was established in
1998, at which time EMS contractually assumed certain of the Company's
environmental liabilities. EMS' earnings are based, in part, upon its ability to
favorably resolve these liabilities on an aggregate basis. The shareholders of
EMS, other than the Company, actively manage the environmental liabilities and
share in 39% of EMS' cumulative earnings. The Company continues to consolidate
EMS and provides accruals for the reasonably estimable costs for the settlement
of EMS' environmental liabilities, as discussed below.

LIQUIDITY AND CAPITAL RESOURCES:

Consolidated cash flows

Summary

The Company's primary source of liquidity on an ongoing short-term and
long-term basis is its cash flows from operating activities, which is generally
used to (i) fund capital expenditures, (ii) repay any short-term indebtedness
incurred primarily for working capital purposes and (iii) provide for the
payment of dividends. In addition, from time-to-time the Company will incur
indebtedness, generally to (i) fund short-term working capital needs, (ii)
refinance existing indebtedness or (iii) fund major capital expenditures or the
acquisition of other assets outside the ordinary course of business. Also, the
Company will from time-to-time sell assets outside the ordinary course of
business, the proceeds of which are generally used to (i) repay existing
indebtedness (including indebtedness which may have been collateralized by the
assets sold), (ii) make investments in marketable and other securities, (iii)
fund major capital expenditures or the acquisition of other assets outside the
ordinary course of business or (iv) pay dividends.

Operating activities

Cash flows from operating activities decreased from $16.8 million provided
by operating activities in the first three months of 2004 to $3.9 million of
cash used by operating activities in the first three months of 2005. This $20.7
million decrease was due primarily to the deconsolidation of Kronos, effective
July 1, 2004. As such, cash from operating activities in the first quarter of
2005 is not comparable to the corresponding period in 2004. Relative changes in
accounts receivable are affected by, among other things, the timing of sales and
the collection of the resulting receivables. Relative changes in inventories and
accounts payable and accrued liabilities are affected by, among other things,
the timing of raw material purchases and the payment for such purchases and the
relative difference between production volumes and sales volumes. Relative
changes in accrued environmental costs are affected by, among other things, the
period in which recognition of the environmental accrual is recognized and the
period in which the remediation expenditure is actually made.

Trends in cash flows from operating activities (excluding the impact of
significant asset dispositions and relative changes in assets and liabilities)
are generally similar to trends in the Company's earnings. However, certain
items included in the determination of net income are non-cash, and therefore
such items have no impact on cash flows from operating activities. Non-cash
items included in the determination of net income include depreciation and
amortization expense, deferred income taxes and non-cash interest expense.
Non-cash interest expense relates principally to Kronos in 2004 and consists of
amortization of deferred financing costs.

Certain other items included in the determination of net income may have an
impact on cash flows from operating activities, but the impact of such items on
cash flows from operating activities will differ from their impact on net
income. For example, equity in earnings of affiliates will generally differ from
the amount of distributions received from such affiliates, and equity in losses
of affiliates does not necessarily result in current cash outlays paid to such
affiliates. The amount of periodic defined benefit pension plan expense and
periodic OPEB expense depends upon a number of factors, including certain
actuarial assumptions, and changes in such actuarial assumptions will result in
a change in the reported expense. In addition, the amount of such periodic
expense generally differs from the outflows of cash required to be currently
paid for such benefits.

Certain other items included in the determination of net income have no
impact on cash flows from operating activities, but such items do impact cash
flows from investing activities (although their impact on such cash flows
differs from their impact on net income). For example, realized gains and losses
from the disposal of long-lived assets are included in the determination of net
income, although the proceeds from any such disposal are shown as part of cash
flows from investing activities.

Relative changes in assets and liabilities generally result from the timing
of production, sales, purchases and income tax payments. Such relative changes
can significantly impact the comparability of cash flow from operations from
period to period, as the income statement impact of such items may occur in a
different period from when the underlying cash transaction occurs. For example,
raw materials may be purchased in one period, but the payment for such raw
materials may occur in a subsequent period. Similarly, inventory may be sold in
one period, but the cash collection of the receivable may occur in a subsequent
period.

NL does not have complete access to the cash flows of its subsidiaries and
affiliates, in part due to limitations contained in certain credit agreements as
well as the fact that certain of such subsidiaries and affiliates are not 100%
owned by NL. A detail of NL's consolidated cash flows from operating activities
is presented in the table below. Eliminations consist of intercompany dividends
(most of which are paid by Kronos to NL in 2004, and by CompX to NL in 2005).

Investing and financing activities

In 2005, substantially all of the Company's consolidated capital
expenditures relate to CompX. During the first quarter of 2005, (i) NL sold
shares of Kronos common stock in market transactions for $19.0 million and (ii)
CompX received a net $18.1 million from the sale of its Thomas Regout operations
(which had approximately $4.0 million of cash at the date of disposal). See
Notes 3 and 14 to the Consolidated Financial Statements.

Distributions to minority interest in 2005 consist of CompX dividends paid
to shareholders other than NL. Other cash flows from financing activities in
2005 relate primarily to proceeds from the issuance of NL and CompX common stock
upon exercise of stock options.

At March 31, 2005, unused credit available under existing credit facilities
approximated $47.5 million, all under CompX's revolving credit facility.

Provisions contained in certain of the Company's and its subsidiaries' and
affiliates' credit agreements could result in the acceleration of the applicable
indebtedness prior to its stated maturity for reasons other than defaults from
failing to comply with typical financial covenants. For example, certain credit
agreements allow the lender to accelerate the maturity of the indebtedness upon
a change of control (as defined) of the borrower. In addition, certain credit
agreements could result in the acceleration of all or a portion of the
indebtedness following a sale of assets outside the ordinary course of business,
which provision was waived in connection with CompX's sale of its Thomas Regout
operations. Other than operating leases discussed in the 2004 Annual Report,
neither NL nor any of its subsidiaries or affiliates are parties to any
off-balance sheet financing arrangements.

Component products - CompX

CompX received approximately $18.1 million cash (net of expenses) in
January 2005 upon the sale of its Thomas Regout operations in the Netherlands.
See Note 14 to the Consolidated Financial Statements. CompX believes that its
cash on hand, together with cash generated from operations and borrowing
availability under its bank credit facility, will be sufficient to meet CompX's
liquidity needs for working capital, capital expenditures, debt service and
dividends. To the extent that CompX's actual operating results or developments
differ from CompX's expectations, CompX's liquidity could be adversely affected.
CompX, which had suspended its regular quarterly dividend of $.125 per share in
the second quarter of 2003, reinstated its regular quarterly dividend at the
$.125 per share rate in the fourth quarter of 2004.

Certain of the CompX's sales generated by its non-U.S. operations are
denominated in U.S. dollars. CompX periodically uses currency forward contracts
to manage a very nominal portion of foreign exchange rate risk associated with
receivables denominated in a currency other than the holder's functional
currency or similar exchange rate risk associated with future sales. CompX has
not entered into these contracts for trading or speculative purposes in the
past, nor does CompX currently anticipate entering into such contracts for
trading or speculative purposes in the future. Derivatives used to hedge
forecasted transactions and specific cash flows associated with foreign currency
denominated financial assets and liabilities which meet the criteria for hedge
accounting are designated as cash flow hedges. Consequently, the effective
portion of gains and losses is deferred as a component of accumulated other
comprehensive income and is recognized in earnings at the time the hedged item
affects earnings. Contracts that do not meet the criteria for hedge accounting
are marked-to-market at each balance sheet date with any resulting gain or loss
recognized in income currently as part of net currency transactions. To manage
such exchange rate risk, at March 31, 2005, CompX held a series of contracts,
which matured in May 2005, to exchange an aggregate of U.S. $2.5 million for an
equivalent amount of Canadian dollars at an exchange rates of Cdn. $1.20 to Cdn.
$1.23 per U.S. dollar. At March 31, 2005, the actual exchange rate was Cdn.
$1.21 per U.S. dollar. The estimated fair values of such foreign currency
forward contracts at March 31, 2005 is not material.

CompX periodically evaluates its liquidity requirements, alternative uses
of capital, capital needs and available resources in view of, among other
things, its capital expenditure requirements, dividend policy and estimated
future operating cash flows. As a result of this process, CompX has in the past
and may in the future seek to raise additional capital, refinance or restructure
indebtedness, issue additional securities, modify its dividend policy,
repurchase shares of its common stock or take a combination of such steps or
other steps to manage its liquidity and capital resources. In the normal course
of business, CompX may review opportunities for acquisitions, divestitures,
joint ventures or other business combinations in the component products
industry. In the event of any such transaction, CompX may consider using cash,
issuing additional equity securities or increasing the indebtedness of CompX or
its subsidiaries.

Chemicals - Kronos

At March 31, 2005, Kronos had cash, cash equivalents and marketable debt
securities of $42.1 million, including restricted balances of $3.7 million, and
Kronos had approximately $143 million available for borrowing under its U.S.,
Canadian and European credit facilities. Based upon Kronos' expectations for the
TiO2 industry and anticipated demands on Kronos' cash resources as discussed
herein, Kronos expects to have sufficient liquidity to meet its future
obligations including operations, capital expenditures, debt service and current
dividend policy. To the extent that actual developments differ from Kronos'
expectations, Kronos' liquidity could be adversely affected.

At March 31, 2005, Kronos' outstanding debt was comprised of (i) $493.0
million related to KII's Senior Secured Notes, (ii) $12.9 million related to
KII's European revolving bank credit facility which matures in June 2005 and
(iii) approximately $300,000 of other indebtedness. KII expects to seek to renew
its European revolving bank credit facility during the second quarter of 2005.

Kronos' assets consist primarily of investments in its operating
subsidiaries, and Kronos' ability to service its parent level obligations,
including the Senior Secured Notes, depends in large part upon the distribution
of earnings of its subsidiaries, whether in the form of dividends, advances or
payments on account of intercompany obligation, or otherwise. None of Kronos'
subsidiaries have guaranteed the Senior Secured Notes, although KII has pledged
65% of the common stock or other ownership interest of certain of KII's
first-tier operating subsidiaries as collateral of such Senior Secured Notes.

As disclosed in the 2004 Annual Report, KII may redeem up to 35% of the
Senior Secured Notes on or before June 30, 2005 with the net proceeds of a
qualified public offering of equity securities of either Kronos or KII. KII
currently has no plans to so redeem the Senior Secured Notes, although until the
June 30, 2005 date passes, KII retains the right to so redeem the Senior Secured
Notes.

Pricing within the TiO2 industry is cyclical, and changes in industry
economic conditions significantly impact Kronos' earnings and operating cash
flows. Cash flows from operations is considered the primary source of liquidity
for Kronos. Changes in TiO2 pricing, production volumes and customer demand,
among other things, could significantly affect the liquidity of Kronos.

Based upon Kronos' expectations for the TiO2 industry and anticipated
demand for Kronos' cash resources as discussed herein, Kronos expects to have
sufficient short-term and long-term liquidity to meet its obligations including
operations, capital expenditures, debt service and dividends. To the extent that
actual developments differ from Kronos' expectations, Kronos' liquidity could be
adversely affected.

See Note 11 to the Consolidated Financial Statements for certain income tax
examinations currently underway with respect to certain of Kronos' income tax
returns in various U.S. and non-U.S. jurisdictions, and see Note 13 to the
Consolidated Financial Statements with respect to certain legal proceedings with
respect to Kronos.

Certain of the Kronos' sales generated by its non-U.S. operations are
denominated in U.S. dollars. Kronos periodically uses currency forward contracts
to manage a very nominal portion of foreign exchange rate risk associated with
receivables denominated in a currency other than the holder's functional
currency or similar exchange rate risk associated with future sales. Kronos has
not entered into these contracts for trading or speculative purposes in the
past, nor does Kronos currently anticipate entering into such contracts for
trading or speculative purposes in the future. Derivatives used to hedge
forecasted transactions and specific cash flows associated with foreign currency
denominated financial assets and liabilities which meet the criteria for hedge
accounting are designated as cash flow hedges. Consequently, the effective
portion of gains and losses is deferred as a component of accumulated other
comprehensive income and is recognized in earnings at the time the hedged item
affects earnings. Contracts that do not meet the criteria for hedge accounting
are marked-to-market at each balance sheet date with any resulting gain or loss
recognized in income currently as part of net currency transactions. To manage
such exchange rate risk, at March 31, 2005, Kronos held a contract, which
matured in April, 2005 to exchange an aggregate of U.S. $5 million for an
equivalent amount of Canadian dollars at an exchange rate of Cdn. $1.24 per U.S.
dollar. At March 31, 2005, the actual exchange rate was Cdn. $1.21 per U.S.
dollar. The estimated fair values of such foreign currency forward contracts at
March 31, 2005 is insignificant.

Kronos periodically evaluates its liquidity requirements, alternative uses
of capital, capital needs and availability of resources in view of, among other
things, its dividend policy, its debt service and capital expenditure
requirements and estimated future operating cash flows. As a result of this
process, Kronos has in the past and may in the future seek to reduce, refinance,
repurchase or restructure indebtedness, raise additional capital, repurchase
shares of its common stock, modify its dividend policy, restructure ownership
interests, sell interests in subsidiaries or other assets, or take a combination
of such steps or other steps to manage its liquidity and capital resources. In
the normal course of its business, Kronos may review opportunities for the
acquisition, divestiture, joint venture or other business combinations in the
chemicals or other industries, as well as the acquisition of interests in, and
loans to, related entities. In the event of any such transaction, Kronos may
consider using available cash, issuing equity securities or increasing
indebtedness to the extent permitted by the agreements governing Kronos'
existing debt.

Kronos has substantial operations located outside the United States for
which the functional currency is not the U.S. dollar. As a result, the reported
amounts of Kronos' assets and liabilities related to its non-U.S. operations,
and therefore Kronos' net assets, will fluctuate based upon changes in currency
exchange rates.

NL Industries

At March 31, 2005, NL (exclusive of CompX) had cash, cash equivalents and
marketable debt securities of $114.5 million, including restricted balances of
$17.5 million. Of such restricted balances, $14 million was held by special
purpose trusts, the assets of which can only be used to pay for certain of NL's
future environmental remediation and other environmental expenditures. See Note
13 to the Consolidated Financial Statements.

See Note 11 to the Consolidated Financial Statements for certain income tax
examinations currently underway with respect to certain of NL's income tax
returns, and see Note 13 to the Consolidated Financial Statements and Part II,
Item 1, "Legal Proceedings" with respect to certain legal proceedings and
environmental matters with respect to NL.

In addition to those legal proceedings described in Note 13 to the
Consolidated Financial Statements, various legislation and administrative
regulations have, from time to time, been proposed that seek to (i) impose
various obligations on present and former manufacturers of lead pigment and
lead-based paint with respect to asserted health concerns associated with the
use of such products and (ii) effectively overturn court decisions in which NL
and other pigment manufacturers have been successful. Examples of such proposed
legislation include bills which would permit civil liability for damages on the
basis of market share, rather than requiring plaintiffs to prove that the
defendant's product caused the alleged damage, and bills which would revive
actions barred by the statute of limitations. While no legislation or
regulations have been enacted to date that are expected to have a material
adverse effect on NL's consolidated financial position, results of operations or
liquidity, imposition of market share liability or other legislation could have
such an effect.

NL previously filed an action against certain of its former insurance
carriers for coverage with respect to defense costs related to certain specific
lead pigment litigation matters. This action was settled in 2000. The Company is
continuing discussions with certain former insurance carriers for coverage with
respect to defense costs related to the Company's remaining past and present
lead pigment litigation matters. Whether insurance coverage for defense costs
will be found to exist for lead pigment litigation depends on a variety of
factors, and there can be no assurance that the Company will be successful in
obtaining reimbursement for past or future defense costs incurred. The Company
has not considered any potential insurance recoveries for lead pigment
litigation in determining related accruals.

NL periodically evaluates its liquidity requirements, alternative uses of
capital, capital needs and availability of resources in view of, among other
things, its dividend policy, its debt service and capital expenditure
requirements and estimated future operating cash flows. As a result of this
process, NL has in the past and may in the future seek to reduce, refinance,
repurchase or restructure indebtedness, raise additional capital, repurchase
shares of its common stock, modify its dividend policy, restructure ownership
interests, sell interests in subsidiaries or other assets, or take a combination
of such steps or other steps to manage its liquidity and capital resources. In
the normal course of its business, NL may review opportunities for the
acquisition, divestiture, joint venture or other business combinations in the
chemicals or other industries, as well as the acquisition of interests in, and
loans to, related entities. In the event of any such transaction, NL may
consider using its available cash, issuing its equity securities or increasing
its indebtedness to the extent permitted by the agreements governing NL's
existing debt.

Because NL's operations are conducted primarily through its subsidiaries
and affiliates, NL's long-term ability to meet its parent company level
corporate obligations is dependent in large measure on the receipt of dividends
or other distributions from its subsidiaries and affiliates. In the fourth
quarter of 2004, CompX reinstated its regular quarterly dividend at the $.125
per share rate. At that rate, and based on the 10.4 million shares of CompX held
indirectly by NL through CompX Group, Inc. ("CGI") (representing NL's pro-rata
ownership of CGI's ownership of CompX) at March 31, 2005, NL would receive
aggregate annual dividends from CompX of $5.2 million. In February 2004, Kronos
announced it would pay its first regular quarterly cash dividend of $.25 per
share. At that rate, and based on the 17.5 million shares of Kronos held by NL
at March 31, 2005, NL would receive aggregate annual dividends from Kronos of
$17.5 million.

The Company routinely compares its liquidity requirements and alternative
uses of capital against the estimated future cash flows to be received from its
subsidiaries, and the estimated sales value of those units. As a result of this
process, the Company has in the past and may in the future seek to raise
additional capital, refinance or restructure indebtedness, repurchase
indebtedness in the market or otherwise, modify its dividend policies, consider
the sale of interests in subsidiaries, affiliates, business units, marketable
securities or other assets, or take a combination of such steps or other steps,
to increase liquidity, reduce indebtedness and fund future activities. Such
activities have in the past and may in the future involve related companies.

The Company and related entities routinely evaluate acquisitions of
interests in, or combinations with, companies, including related companies,
perceived by management to be undervalued in the marketplace. These companies
may or may not be engaged in businesses related to the Company's current
businesses. The Company intends to consider such acquisition activities in the
future and, in connection with this activity, may consider issuing additional
equity securities and increasing the indebtedness of the Company, its
subsidiaries and related companies. From time to time, the Company and related
entities also evaluate the restructuring of ownership interests among their
respective subsidiaries and related companies.

Non-GAAP financial measures

In an effort to provide investors with additional information regarding the
Company's results of operations as determined by GAAP, the Company has disclosed
certain non-GAAP information which the Company believes provides useful
information to investors.

o The Company discloses percentage changes in Kronos' average TiO2 selling
prices in billing currencies, which excludes the effects of foreign
currency translation. The Company believes disclosure of such percentage
changes allows investors to analyze such changes without the impact of
changes in foreign currency exchange rates, thereby facilitating
period-to-period comparisons of the relative changes in average selling
prices in the actual various billing currencies. Generally, when the U.S.
dollar either strengthens or weakens against other currencies, the
percentage change in average selling prices in billing currencies will be
higher or lower, respectively, than such percentage changes would be using
actual exchange rates prevailing during the respective periods.

ITEM 4. CONTROLS AND PROCEDURES

General. As discussed in Note 2 to the Consolidated Financial Statements,
the Company and its audit committee has concluded that the Company will restate
its consolidated financial statements as of December 2004 and for the year then
ended, to reflect an additional $4.2 million, or $.08 per diluted share, noncash
income tax benefit in its results of operations for the year ended December 31,
2004. Such $4.2 million relates to recognition of an additional deferred income
tax benefit related to discontinued operations, to be recognized in the fourth
quarter of 2004 as a component of discontinued operations.

The guidance set forth in Auditing Standard No. 2 ("AS2") of the Public
Company Accounting Oversight Board states that restatement of previously-issued
financial statements to reflect the correction of a misstatement should be
regarded as at least a significant control deficiency and as a strong indicator
that a material weakness in internal control over financial reporting exists. In
connection with this restatement, the Company has concluded that a material
weakness existed as of December 31, 2004 which precludes the Company from
concluding that its internal control over financial reporting was effective as
of December 31, 2004. Therefore, the Company's previous conclusion, as reported
in the Company's Management Report on Internal Control Over Financial Reporting
contained in Item 9A of its Annual Report on Form 10-K for the year ended
December 31, 2004 (as filed on March 30, 2005), that it maintained effective
internal control over financial reporting as of December 31, 2004, as set forth
in its Annual Report on Form 10-K for the year ended December 31, 2004, will be
restated, in which the Company (i) will conclude it lacked effective controls as
of December 31, 2004 surrounding the proper consideration of the effect of
subsequent events on the evaluation of certain income tax attributes and related
deferred income tax asset valuation allowances in the preparation of its
December 31, 2004 consolidated financial statements and (ii) expects that the
Company's independent registered public accounting firm will issue an opinion
stating that the Company did not maintain effective internal control over
financial reporting as of December 31, 2004.

In order to remediate this material weakness, in May 2005, and in
connection with the Company's quarterly close process for the quarter ended
March 31, 2005, the Company has enhanced its focus and instituted additional
procedures, to be performed each quarter in connection with the Company's close
process, that are designed to help ensure that subsequent events are properly
evaluated as they pertain to the evaluation of income tax attributes and related
deferred income tax asset valuation allowances in the preparation of its
consolidated financial statements. Such actions taken with respect to this
enhanced focus and additional procedures instituted include:

o The Company formed a formal committee comprised of the Company's Tax
Director and Chief Financial Officer. Immediately before the Company's
consolidated financial statements are issued each quarter, such committee
will meet and discuss events or circumstances that have arisen subsequent
to the balance sheet date, and will evaluate any such events or
circumstances to consider whether any additional evidence has arisen that
would justify (i) reversal of an existing valuation allowance or (ii)
recognizing a valuation allowance for an existing gross deferred tax asset
without any current valuation allowance, and
o Prior to such meeting, the Company's Chief Financial Officer will review
applicable resource materials regarding the evaluation of deferred income
tax asset valuation allowances and the effect on such evaluation of
subsequent events, in order to provide a proper focus in such meeting on
the effect of any subsequent events.

On May 9 and 10, and in connection with the Company's quarterly close
process for its quarter ended March 31, 2005, this committee met and discussed
the items as described above. The Company has remediated this weakness as of May
10, 2005 (the date of this Form 10-Q for the quarter ended March 31, 2005).

Evaluation of Disclosure Controls and Procedures. The Company maintains a
system of disclosure controls and procedures. The term "disclosure controls and
procedures," as defined by regulations of the SEC, means controls and other
procedures that are designed to ensure that information required to be disclosed
in the reports that the Company files or submits to the SEC under the Securities
Exchange Act of 1934, as amended (the "Act"), is recorded, processed, summarized
and reported, within the time periods specified in the SEC's rules and forms.
Disclosure controls and procedures include, without limitation, controls and
procedures designed to ensure that information required to be disclosed by the
Company in the reports that it files or submits to the SEC under the Act is
accumulated and communicated to the Company's management, including its
principal executive officer and its principal financial officer, or persons
performing similar functions, as appropriate to allow timely decisions to be
made regarding required disclosure. Each of Harold C. Simmons, the Company's
Chief Executive Officer, and Gregory M. Swalwell, the Company's Vice President,
Finance and Chief Financial Officer, has evaluated the Company's disclosure
controls and procedures as of March 31, 2005. Based upon their evaluation, and
solely as a result of the material weakness discussed above, these executive
officers have concluded that the Company's disclosure controls and procedures
were not effective as of the date of such evaluation. However, as discussed
above, in May 2005, and in connection with the Company's quarterly close process
for the quarter ended March 31, 2005, the Company has enhanced its focus and
instituted additional procedures, to be performed each quarter in connection
with the Company's close process, that are designed to help ensure that
subsequent events are properly evaluated as they pertain to the evaluation of
income tax attributes and related deferred income tax asset valuation allowances
in the preparation of its consolidated financial statements. Therefore, these
executive officers have concluded that the Company's disclosure controls and
procedures were effective as of May 10, 2005 (the date of this Form 10-Q for the
quarter ended March 31, 2005).

Internal Control Over Financial Reporting. The Company also maintains
internal control over financial reporting. The term "internal control over
financial reporting," as defined by regulations of the SEC, means a process
designed by, or under the supervision of, the Company's principal executive and
principal financial officers, or persons performing similar functions, and
effected by the Company's board of directors, management and other personnel, to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with GAAP, and includes those policies and procedures that:

o Pertain to the maintenance of records that in reasonable detail accurately
and fairly reflect the transactions and dispositions of the assets of the
Company,
o Provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with GAAP, and
that receipts and expenditures of the Company are being made only in
accordance with authorizations of management and directors of the Company,
and
o Provide reasonable assurance regarding prevention or timely detection of an
unauthorized acquisition, use or disposition of the Company's assets that
could have a material effect on the Company's Consolidated Financial
Statements.

Changes in Internal Control Over Financial Reporting. There has been no
change to the Company's internal control over financial reporting during the
quarter ended March 31, 2005 that has materially affected, or is reasonably
likely to materially affect, the Company's internal control over financial
reporting. However, as discussed above, in May 2005, and in connection with the
Company's quarterly close process for the quarter ended March 31, 2005, the
Company has enhanced its focus and instituted additional procedures, to be
performed each quarter in connection with the Company's close process, that are
designed to help ensure that subsequent events are properly evaluated as they
pertain to the evaluation of income tax attributes and related deferred income
tax asset valuation allowances in the preparation of its consolidated financial
statements. Therefore, the Company has remediated the weakness discussed above
as of May 10, 2005 (the date of this Form 10-Q for the quarter ended March 31,
2005).
