NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 - Basis of presentation and accounting principles newly adopted in 2006:

The consolidated balance sheet of CompX International Inc. and Subsidiaries
(collectively,  the  "Company") at December 31, 2005 has been condensed from the
Company's  audited   consolidated   financial   statements  at  that  date.  The
consolidated balance sheet at March 31, 2006 and the consolidated  statements of
income,  comprehensive  income,  stockholders'  equity  and cash  flows  for the
interim periods ended March 31, 2005 and 2006 have been prepared by the Company,
without audit. In the opinion of management, all adjustments, consisting only of
normal  recurring  adjustments,  necessary  to present  fairly the  consolidated
financial  position,  results of operations  and cash flows have been made.  The
results of operations for the interim periods are not necessarily  indicative of
the  operating  results for a full year or of future  operations.  The  year-end
balance sheet data was derived from audited financial  statements,  but does not
include all disclosures required by accounting  principles generally accepted in
the United States of America ("GAAP").  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, 2005 (the "2005 Annual Report").

Basic earnings per share of common stock is based upon the weighted average
number of  common  shares  actually  outstanding  during  each  period.  Diluted
earnings per share of common stock includes the impact of  outstanding  dilutive
stock options.

Commitments and contingencies are discussed in the 2005 Annual Report.

At March 31, 2006,  CompX Group,  Inc., a  majority-owned  subsidiary of NL
Industries, Inc. (NYSE: NL) owned 83% of the Company's outstanding common stock.
NL owns 82% of CompX Group,  and a wholly owned  subsidiary  of Titanium  Metals
Corporation (NYSE:TIE) ("TIMET") owns the remaining 18% of CompX Group. At March
31, 2006,  (i) NL and TIMET own an  additional 2% and 3%  respectively  of CompX
directly,  (ii) Valhi, Inc. (NYSE: VHI) holds, directly or through a subsidiary,
approximately  83% of NL's  outstanding  common stock and  approximately  37% of
TIMET's outstanding common stock and (iii) Contran  Corporation holds,  directly
or through subsidiaries,  approximately 92% 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 and the Company.

Inventory  costs.  The Company  adopted 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

- 9 -

costs  are  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; therefore, the effect on the consolidated
financial statements as a result of the adoption of SFAS No. 151 was immaterial.

Stock options.  In accordance  with  regulations  set forth by the SEC, the
Company adopted SFAS No. 123R,  Share-Based Payment, as of January 1, 2006. 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, 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,  if the
instrument is forfeited before it has vested). The grant-date fair value will be
estimated using  option-pricing  models (e.g.  Black-Sholes 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  previously  measured
under  SFAS No. 123 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 the
Company was not material,  the effect of adopting SFAS No. 123R, in so far as it
relates to the  recognition of compensation  cost in the Company's  consolidated
statements of income for existing stock options,  did not have a material effect
on the Company's consolidated financial statements. Should the Company, however,
either grant a  significant  number of options or modify,  repurchase  or cancel
existing  options in the  future,  the  Company  could in the  future  recognize
material   amounts  of  compensation   cost  related  to  such  options  in  its
consolidated financial statements.

Also upon adoption of SFAS No. 123R, the cash income tax benefit  resulting
from the  exercise  of stock  options  in excess of the  cumulative  income  tax
benefit  related  to such  options  previously  recognized  for  GAAP  financial
reporting purposes in the Company's  consolidated  statements of income, if any,
will be reflected as a cash inflow from  financing  activities  in the Company's
consolidated  statements  of cash  flows,  and the  Company's  cash  flows  from
operating  activities  will  reflect  the effect of cash paid for  income  taxes
exclusive  of such cash income tax  benefit.  No stock  options  were  exercised
during the first  quarter of 2006;  therefore,  no such income tax benefits have
been recognized as a component of cash flows from financing  activities at March
31, 2006.

SFAS No. 123R also  requires  certain  expanded  disclosures  regarding the
Company's stock options, and such expanded disclosures were provided in the 2005
Annual Report.

Prior to January 1, 2006, the Company  accounted for  stock-based  employee
compensation  related  to stock  options  using the  intrinsic  value  method in
accordance with Accounting  Principles Board Opinion ("APBO") No. 25, Accounting
for Stock Issued to Employees, and its various  interpretations.  Under APBO No.
25, no  compensation  cost was generally  recognized  for fixed stock options in
which the  exercise  price is greater  than or equal to the market  price on the
grant date. Compensation cost recognized by the Company related to stock options
was not  significant  during the first  three  months of 2005 or the first three

- 10 -

months of 2006. If the Company had applied the fair value recognition provisions
of Statement of Financial  Accounting Standards ("SFAS") No. 123, Accounting for
Stock-Based Compensation,  to stock-based employee compensation related to stock
options for all options  granted on or after January 1, 1995,  the effect on the
Company's  results of  operations  for the first three  months of 2005 would not
have been material.

Note 2 - Business segment information:

The  Company's   operating  segments  are  defined  as  components  of  its
operations  about which  separate  financial  information  is available  that is
regularly  evaluated by the chief operating decision maker in determining how to
allocate resources and in assessing  performance.  The Company's chief operating
decision maker is David A. Bowers,  president and chief executive officer of the
Company.  The Company  currently has two operating  segments - Security Products
and Furniture  Components.  The Security  Products segment,  with  manufacturing
facilities in South Carolina and Illinois,  manufactures  locking mechanisms and
other  security  products  for  sale to the  mailbox,  transportion,  furniture,
banking,  vending and other industries.  The Furniture Components segment,  with
facilities  in Canada,  Michigan  and  Taiwan,  manufacture  a complete  line of
precision ball bearing slides and ergonomic  computer support systems for use in
office furniture,  computer-related  equipment,  tool storage cabinets and other
applications.

Previously,  the Company had three operating  segments:  Security Products,
Precision Slides, and Ergonomics.  During the first quarter of 2006, the Company
changed its internal  management  structure  such that its precision  slides and
ergonomics  products  businesses  are now evaluated as a single  operating  unit
(referred to as Furniture  Components).  Segment  information  at March 31, 2006
reflects the new internal management structure.  Additionally, in prior periods,
the reported amount of operating  income for each operating  segment included an
allocation  of  corporate  operating  expenses  based  upon the  amount  of each
segment's net sales. At March 31, 2006, such corporate expenses have not been so
allocated but instead are presented as a separate item within operating  income.
Prior period  segment  information  has been  restated to conform to the current
period presentation for all items as mentioned above.

Note 8 - Currency forward exchange contracts:

Certain of the Company's  sales  generated by its non-U.S.  operations  are
denominated in U.S.  dollars.  The Company  periodically  uses currency  forward
contracts to manage a portion of currency  exchange rate market risk  associated
with  receivables,  or similar  exchange rate risk associated with future sales,
denominated  in a currency  other than the  holder's  functional  currency.  The
Company has not entered into these contracts for trading or speculative purposes
in the  past,  nor does the  Company  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.  At March 31,  2006,  the Company  held a series of  contracts  to
manage such exchange rate risk to exchange an aggregate of U.S. $5.2 million for
Canadian  dollars  at an  exchange  rate of Cdn.  $1.16  per U.S.  dollar.  Such
contracts  qualify  for hedge  accounting  and mature  through  June  2006.  The
exchange rate was Cdn.  $1.17 per U.S.  dollar at March 31, 2006.  The estimated
fair value of such contracts is not material at March 31, 2006.

Note 9 - Discontinued operations:

Discontinued  operations  relates to the  Company's  former  Thomas  Regout
operations in the Netherlands. In January 2005, CompX completed the sale of such
operations  for  net  proceeds  that  were  approximately   $864,000  less  than
previously  estimated  (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  ($477,000,
net of income tax benefit).

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF  FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS
-------------------------------------------------------------------------------

Overview

The Company reported  operating income of $4.8 million in the first quarter
of 2006  compared to operating  income of $4.1 million for the first  quarter of
2005. The operating  income  improved due to a more  favorable  product mix, the
impact of the acquisition of a small components  business in August 2005 and the
Company's ongoing focus on reducing costs.

Net sales.  Net sales of $47.0  million  in the first  quarter of 2006 were
comparable  with net sales of $46.8  million in the first  quarter of 2005.  Net
sales were  impacted  by a general  increase  in sales  volume  within  security
products  and other,  partially  offset by sales  volume  decreases  for certain
Furniture Components products resulting from increased competition.

Cost of goods sold.  The Company's  cost of goods sold  decreased 3% in the
first  quarter of 2006  compared  to 2005 while net sales were flat for the same
period.  The Company's  gross margin  percentage  increased from 22% in the 2005
period to 25% in the 2006 period.  This improvement  resulted from the favorable
impact of a continuous focus on reducing costs across all segments and increases
in sales of higher margin products within security products.

Selling, general, and administrative expense. As a percentage of net sales,
selling,  general,  and administrative  expense was 13% of net sales in 2005 and
14% in 2006.

Operating  income.  Operating income in the first quarter of 2006 increased
to $4.8  million  compared to $4.1 million for the first  quarter of 2005.  As a
percentage of net sales, operating income increased to 10% for the first quarter
of 2006 from 9% for the first  quarter of 2005 due to the  improvement  in gross
margins discussed above.

Currency.  CompX has substantial  operations and assets located outside the
United States (in Canada and Taiwan).  A portion of CompX's sales generated from

- 16 -

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  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. The effects of fluctuations
in currency exchange rates affect the Furniture  Components segment,  and do not
materially  affect  the  Security  Products  segment.  Fluctuations  in  foreign
currency exchange rates did not have a significant  effect on sales or operating
income in the first quarter of 2006 as compared to the first quarter of 2005.

Other  non-operating  income,  net. The  components of other  non-operating
income, net are summarized in Note 6 to the Consolidated  Financial  Statements,
and primarily include interest income.

Interest  expense.  Interest  expense declined in the first quarter of 2006
compared to the first quarter of 2005 due  primarily to lower average  levels of
outstanding debt.

Provision  for income  taxes.  The  principal  reasons  for the  difference
between CompX's effective income tax rates and the U.S. federal statutory income
tax rates are  explained  in Note 7 to the  Consolidated  Financial  Statements.
Income  tax rates vary by  jurisdiction  (country,  county  and/or  state),  and
relative changes in the geographic mix of CompX's pre-tax earnings can result in
fluctuations in the effective income tax rate.

CompX became a member of Contran's  consolidated  U.S.  federal  income tax
group (the  "Contran Tax Group") in October 2004. As a member of the Contran Tax
Group,  CompX  computes its  provision  for income  taxes on a separate  company
basis, using the tax elections made by Contran.  One such election is whether to
claim a deduction or a tax credit  against U.S.  taxable  income with respect to
foreign income taxes paid.  Consistent  with elections of the Contran Tax Group,
in 2005 and 2006 CompX is not claiming a credit with  respect to foreign  income
taxes paid but instead is claiming a tax deduction. This is the primary cause of
the Company's  effective  income tax rate for the periods  ending March 31, 2005
and 2006 being higher than the U.S. federal statutory income tax rate.

Outlook.  The component product areas where the Company operates are highly
competitive in terms of product pricing and features.  The Company's strategy is
to  focus  on  areas  where  it can  provide  products  that  have  value-added,
user-oriented features which enable its customers to compete more effectively in
their  markets.  One of the focal  points of this  strategy  is to  replace  low
margin,  commodity  type  products  with  higher  margin  user-oriented  feature
products.  Additionally,  it  believes  that  its  focus on  collaborating  with
customers  to  identify  solutions  and its  ability  to provide a high level of
customer  service enable it to compete  effectively.  In response to competitive
pricing pressure,  the Company  continuously focuses on reducing production cost
through product reengineering,  improvement in manufacturing processes or moving
production to lower-cost facilities.

Raw material  prices,  especially  steel,  zinc and copper,  continue to be
volatile  putting  pressure on CompX's  margins.  The Company  actively seeks to
mitigate the margin  impact by entering into raw material  supply  agreements in
order to stabilize the cost for a period of time, execute larger volume tactical
spot  purchases at prices that are  expected to be favorable  compared to future
prices  and, if  necessary,  pass on the cost  increases  to  customers  through
surcharges and price increases.

Accounting principles newly adopted in 2006. See Note 1 to the Consolidated
Financial Statements.

Liquidity and Capital Resources

Summary.

The Company's  primary  source of liquidity on an ongoing basis is its cash
flow from  operating  activities,  which is  generally  used to (i) fund capital
expenditures,  (ii) repay indebtedness incurred primarily for working capital or
capital expenditure  purposes and (iii) provide for the payment of dividends (if
declared). From time-to-time, the Company will incur indebtedness, primarily for
short-term  working  capital needs or to fund capital  expenditures  or business
combinations.  In addition, from time-to-time,  the Company may also sell assets
outside the  ordinary  course of business,  the proceeds of which are  generally
used  to  repay  indebtedness   (including  indebtedness  which  may  have  been
collateralized  by the assets sold) or to fund capital  expenditures or business
combinations.

At March 31, 2006,  there were no amounts  outstanding  under the Company's
credit  facility  that matures in January  2009.  The Company does not expect it
will be required to use any of its cash flow from operating activities generated
during 2006 to repay indebtedness.

Consolidated cash flows.

Operating  activities.  Trends in cash  flows  from  operating  activities,
excluding  changes in assets and liabilities  have generally been similar to the
trends in the  Company's  earnings.  Changes  in assets and  liabilities  result
primarily  from the timing of production,  sales and purchases.  Such changes in
assets  and  liabilities   generally  tend  to  even  out  over  time.  However,
period-to-period  relative  changes in assets and liabilities can  significantly
affect the comparability of cash flows from operating  activities.  Such changes
in assets and liabilities  resulted in a net use of cash of  approximately  $3.3
million  in the  first  quarter  of 2005  compared  to a net use of cash of $2.2
million in the first quarter of 2006.

As noted above,  relative changes in working capital can have a significant
effect on cash flows from operating activities. The Company's average days sales
outstanding  increased from 40 days at December 31, 2005 to 44 days at March 30,
2006 due to timing of collection and a higher accounts receivable balance at the
end of March.  The Company's  average number of days in inventory was 59 days at
December  31,  2005 and 57 days at  March  31,  2006.  The  decrease  in days in
inventory is primarily due to lower raw materials inventory.

Investing  activities.  Net cash provided by investing  activities  totaled
$9.0 million in the first quarter of 2005 compared to net cash used by investing
activities  of $2.6  million  in the first  quarter  of 2006.  Net cash for 2005
included  the net  proceeds  from the sale of the Thomas  Regout  operations  in
Europe discussed below.

On January 24, 2005,  CompX  completed  the  disposition  of all of the net
assets of its Thomas Regout  precision slide and window  furnishing  operations,
conducted  at its  facility  in the  Netherlands,  to members  of Thomas  Regout
management  for net  proceeds  of  approximately  $22.3  million.  The  proceeds
consisted of cash (net of costs to sell) of  approximately  $18.1  million and a
subordinated Note for approximately $4.2 million. The subordinated note requires
annual  payments  over a period of four years.  Historically,  the Thomas Regout
European  operations had not  contributed  significantly  to net cash flows from
operations.

Firm purchase commitments for capital projects in process at March 31, 2006
approximated $4.7 million.

- 18 -

Financing  activities.  Net cash used by financing  activities totaled $1.7
million and $3.5  million in the first  quarter of 2005 and 2006,  respectively.
The Company  prepaid  certain  industrial  revenue  bonds  reducing debt by $1.5
million  in the  first  quarter  of 2006 and paid  quarterly  dividends  of $1.9
million,   or  $.125  per  share,  in  the  first  quarter  of  2005  and  2006,
respectively.

Provisions contained in the Company's Revolving Bank Credit Agreement could
result in the  acceleration  of  outstanding  indebtedness  prior to its  stated
maturity  for reasons  other than  defaults  from failing to comply with typical
financial  covenants.  For example,  the Company's  Credit  Agreement allows the
lender to accelerate the maturity of the  indebtedness  upon a change of control
(as defined) of the borrower.  The terms of the Company's Credit Agreement could
result in the acceleration of all or a portion of the  indebtedness  following a
sale of assets outside of the ordinary course of business.

Other.   Management  believes  that  cash  generated  from  operations  and
borrowing  availability under the Credit Agreement,  together with cash on hand,
will be sufficient to meet the Company's  liquidity  needs for working  capital,
capital  expenditures,  debt service and dividends (if declared).  To the extent
that the Company's actual operating  results or other  developments  differ from
the Company's expectations, CompX's liquidity could be adversely affected.

The Company 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, the Company has in the
past  and may in the  future  seek to raise  additional  capital,  refinance  or
restructure indebtedness, issue additional securities,  repurchase shares of its
common stock,  modify its dividend policy or take a combination of such steps to
manage its  liquidity and capital  resources.  In the normal course of business,
the Company may review  opportunities for acquisitions,  joint ventures or other
business  combinations in the component products  industry.  In the event of any
such  transaction,  the Company  may  consider  using  available  cash,  issuing
additional  equity  securities or increasing the  indebtedness of the Company or
its subsidiaries.

Off balance  sheet  financing  arrangements.  Other than certain  operating
leases  discussed  in the  2005  Annual  Report,  neither  CompX  nor any of its
subsidiaries are parties to any off-balance sheet financing arrangements.

Forward Looking Information

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," "anticipates," "expects" 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.  Among the
factors  that could cause actual  future  results to differ  materially  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  Securities  and
Exchange  Commission.  While it is not  possible to identify  all  factors,  the
Company  continues  to face many  risks  and  uncertainties  including,  but not
limited to the following:

- 19 -

o    Future supply and demand for the Company's products,
o    Changes in costs of raw materials and other  operating  costs (such as
energy costs),
o    General global economic and political conditions,
o    Demand for office furniture,
o    Service industry employment levels,
o    The possibility of labor disruptions,
o    Competitive products and prices,  including increased competition from
low-cost manufacturing sources (such as China),
o    Substitute products,
o    Customer and competitor strategies,
o    Costs  and   expenses   associated   with   compliance   with  certain
requirements  of  the  Sarbanes-Oxley  Act  of  2002  relating  to the
evaluation of the Company's internal control over financial reporting,
o    The introduction of trade barriers,
o    The impact of pricing and production decisions,
o    Fluctuations  in the  value  of the  U.S.  dollar  relative  to  other
currencies (such as the Canadian dollar and New Taiwan dollar),
o    Potential    difficulties   in   integrating   completed   or   future
acquisitions,
o    Decisions to sell operating  assets other than in the ordinary  course
of business,
o    Uncertainties associated with new product development,
o    Environmental  matters (such as those requiring emission and discharge
standards for existing and new facilities),
o    The ability of the Company to comply with  covenants  contained in its
revolving bank credit facility,
o    The ultimate outcome of income tax audits,
o    The impact of current or future government regulations,
o    Possible future litigation and o Other risks and uncertainties.

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  publicly  or  revise  such
statements whether as a result of new information, future events or otherwise.

ITEM 3. QUANTITATIVE AND QUALITATITVE DISCLOSURE ABOUT MARKET RISK.

Reference is made to the 2005 Annual  Report for a discussion of the market
risks  associated  with the  changes  in  foreign  currency  exchange  rates and
interest rates that affect the Company.  There have been no material  changes in
such market risks since the Company filed the 2005 Annual Report.

ITEM 4. Controls and Procedures.

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

- 20 -

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 David A. Bowers, the Company's Vice
Chairman of the Board,  President  and Chief  Executive  Officer,  and Darryl R.
Halbert,  the Company's Vice President,  Chief Financial Officer and Controller,
have evaluated the Company's  disclosure controls and procedures as of March 31,
2006. Based upon their evaluation,  these executive officers have concluded that
the Company's  disclosure  controls and procedures are effective as of March 31,
2006.

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  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, 2006 that has  materially  affected,  or is  reasonably
likely to materially  affect,  the  Company's  internal  control over  financial
reporting.
