($ In thousands, except share and per share data)

Note (1)

        The consolidated financial statements of National Bankshares, Inc.
(Bankshares) and its wholly-owned subsidiaries, The National Bank of Blacksburg
(NBB), Bank of Tazewell County (BTC) and National Bankshares Financial Services,
Inc. (NBFS), (the Company), conform to accounting principles generally accepted
in the United States of America and to general practices within the banking
industry. The accompanying interim period consolidated financial statements are
unaudited; however, in the opinion of management, all adjustments consisting of
normal recurring adjustments, which are necessary for a fair presentation of the
consolidated financial statements, have been included. The results of operations
for the three months ended March 31, 2006 are not necessarily indicative of
results of operations for the full year or any other interim period. The interim
period consolidated financial statements and financial information included in
this Form 10-Q should be read in conjunction with the notes to consolidated
financial statements included in the Company's 2005 Form 10-K. The Company posts
all reports required to be filed under the Securities and Exchange Act of 1934
on its web site at www.nationalbankshares.com.

Note (2) Stock-Based Compensation

        The Company adopted the National Bankshares, Inc. 1999 Stock Option Plan
to give key employees of Bankshares and its subsidiaries an opportunity to
acquire shares of National Bankshares, Inc. common stock. The purpose of the
1999 Stock Option Plan is to promote the success of Bankshares and its
subsidiaries by providing an incentive to key employees that enhances the
identification of their personal interest with the long term financial success
of the Company and with growth in stockholder value. Under the 1999 Stock Option
Plan, up to 250,000 shares of Bankshares common stock may be granted. The 1999
Stock Option Plan is administered by the Stock Option Committee, which is the
NBI Board of Directors' Compensation Committee, made up entirely of independent
directors of National Bankshares, Inc. The Stock Option Committee may determine
whether options are incentive stock options or nonqualified stock options and
may determine the other terms of grants, such as number of shares, term, a
vesting schedule, and the exercise price. The 1999 Stock Option Plan limits the
maximum term of any option granted to ten years, states that options may be
granted at not less than fair market value on the date of the grant and contains
certain other limitations on the exercisability of incentive stock options. The
options generally vest 25% after one year, 50% after two years, 75% after three
years and 100% after four years. On December 29, 2005, the Company's Board of
Directors passed a resolution stating that all 142,000 previously granted, but
unvested, stock options be immediately vested. The vesting was made subject to
the provision that any shares of NBI common stock obtained by an option grantee
by exercise of an option subject to accelerated vesting may not be sold or
otherwise transferred prior to the expiration of the option's original vesting
period. This action was taken to reduce the impact of the "Statement of
Financial Accounting Standards No. 123R, Share-Based Payment" on the Company's
earnings over the reminder vesting period of the stock options. At the
discretion of the Stock Option Committee options may be awarded with the
provision that they may be accelerated upon a change of control, merger,
consolidation, sale or dissolution of National Bankshares, Inc. At March 31,
2006, there were 286,000 additional shares available for grant under the plan.
        Compensation expense is calculated using the Black-Scholes model and is
amortized over the requisite service period using the straight-line method.
Please refer to the Company's Form 10-K dated December 31, 2005 for assumptions
used. There have been no grants of stock options in 2006.

        The Company had 260 securities with a fair value of $171,320 which were
temporarily impaired at March 31, 2006. The total unrealized loss on these
securities was $5,071. Losses are attributed to interest rate movements. Credit
quality of the securities portfolio is continuously monitored by management. The
Company has the ability and intent to hold these securities until maturity.
Therefore, the losses associated with these securities are considered temporary
at March 31, 2006. All securities shown are above investment grade.

Note (5) Recent Accounting Pronouncements

        In March 2006, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 156, "Accounting for Servicing of
Financial Assets an amendment of FASB Statement 140" (Statement 156). Statement
156 amends Statement 140 with respect to separately recognized servicing assets
and liabilities. Statement 156 requires an entity to recognize a servicing asset
or liability each time it undertakes an obligation to service a financial asset
by entering into a servicing contract and requires all servicing assets and
liabilities to be initially measured at fair value, if practicable. Statement
156 also permits entities to subsequently measure servicing assets and
liabilities using an amortization method or fair value measurement method. Under
the amortization method, servicing assets and liabilities are amortized in
proportion to and over the estimated period of servicing. Under the fair value
measurement method, servicing assets are measured at fair value at each
reporting date and changes in fair value are reported in net income for the
period the change occurs.

        Adoption of Statement 156 is required as of the beginning of fiscal
years beginning subsequent to September 15, 2006. Earlier adoption is permitted
as of the beginning of an entity's fiscal year, provided the entity has not yet
issued financial statements, including interim financial statements.

        The Corporation does not expect the adoption of Statement 156 at the
beginning of 2007 to have a material impact.

        The purpose of this discussion is to provide information about the
financial condition and results of operations of National Bankshares, Inc. and
its wholly-owned subsidiaries (the Company), which are not otherwise apparent
from the consolidated financial statements and other information included in
this report. Refer to the financial statements and other information included in
this report as well as the 2005 Annual Report on Form 10-K for an understanding
of the following discussion and analysis.

as described in the Securities Exchange Act of 1934. The Company's actual
results could differ materially from those set forth in the forward-looking
statements.

Critical Accounting Policies

General

        The Company's financial statements are prepared in accordance with
accounting principles generally accepted in the United States (GAAP). The
financial information contained within our statements is, to a significant
extent, financial information that is based on measures of the financial effects
of transactions and events that have already occurred. A variety of factors
could affect the ultimate value that is obtained when earning income,

16
<PAGE>

recognizing an expense, recovering an asset or relieving a liability. We use
historical loss factors as one element in determining the inherent loss that may
be present in our loan portfolio. Actual losses could differ significantly from
the historical factors that we use. In addition, GAAP itself may change from one
previously acceptable method to another method. Although the economics of our
transactions would be the same, the timing of events that would impact our
transactions could change.

Allowance for Loan Losses

        The allowance for loan losses is an estimate of the losses that may be
sustained in our loan portfolio. The allowance is based on two basic principles
of accounting: (i) SFAS 5, Accounting for Contingencies, which requires that
losses be accrued when they are probable of occurring and estimable and (ii)
SFAS 114, Accounting by Creditors for Impairment of a Loan, which requires that
losses be accrued based on the differences between the value of collateral,
present value of future cash flows or values that are observable in the
secondary market and the loan balance.
        Our allowance for loan losses has three basic components; the formula
allowance, the specific allowance and the unallocated allowance. Each of these
components is determined based upon estimates that can and do change when actual
events occur. The formula allowance uses a historical loss view and certain
qualitative factors as an indicator of future losses and, as a result, could
differ from the loss incurred in the future. However, since this history is
updated with the most recent loss information, the errors that might otherwise
occur are mitigated. The specific allowance uses various techniques to arrive at
an estimate of loss. Expected cash flows and fair market value of collateral are
used to estimate these losses. The use of these values is inherently subjective
and our actual losses could be greater or less than the estimates. The
unallocated allowance captures losses that are attributable to various economic
events, industry or geographic sectors, whose impact on the portfolio have
occurred but have yet to be recognized in either the formula or specific
allowance.

Core deposit intangibles

        Effective January 1, 2002, the Corporation adopted Financial Accounting
Standards Board Statement No. 142, Goodwill and Other Intangible Assets.
Accordingly, goodwill is no longer subject to amortization over its estimated
useful life, but is subject to at least an annual assessment for impairment by
applying a fair value based test. Additionally, Statement 142 requires that
acquired intangible assets (such as core deposit intangibles) be separately
recognized if the benefit of the asset can be sold, transferred, licensed,
rented, or exchanged and amortized over its estimated useful life. Branch
acquisition transactions were outside the scope of the Statement and therefore
any intangible asset arising from such transactions remained subject to
amortization over their estimated useful life.
        In October 2002, the Financial Accounting Standards Board issued
Statement No. 147, Acquisitions of Certain Financial Institutions. The Statement
amends previous interpretive guidance on the application of the purchase method
of accounting to acquisitions of financial institutions, and requires the
application of Statement No. 141, Business Combinations, and Statement No. 142
to branch acquisitions if such transactions meet the definition of a business
combination. The provisions of the Statement do not apply to transactions
between two or more mutual enterprises. In addition, the Statement amends
Statement No. 144, Accounting for the Impairment of Long-Lived Assets, to
include in its scope core deposit intangibles of financial institutions.
Accordingly, such intangibles are subject to a recoverability test based on
undiscounted cash flows, and to the impairment recognition and measurement
provisions required for other long-lived assets held and used. The Company has
determined that the acquisitions that generated the intangible assets and
goodwill on the consolidated balance sheets in the amount of $9,958 and $10,912
at December 31, 2003 and 2002, respectively, did not constitute the acquisition
of a business, and therefore will continue to be amortized.

Southwest Virginia. It conducts operations primarily through two full-service
banking affiliates, the National Bank of Blacksburg and Bank of Tazewell County.
It also has one nonbanking affiliate, National Bankshares Financial Services,
Inc., which offers investment and insurance products. Net income derived from
the nonbanking affiliate is not significant at this time or in the foreseeable
future. NBI is a community bank operation.

(1)     Net Interest Margin: Year-to-date tax-equivalent net interest income
        divided by year-to-date average earning assets using a tax rate of 35%.
(2)     Noninterest Margin: Noninterest income (including securities gains and
        losses) less noninterest expense (excluding the provision for bad debts
        and income taxes) divided by average year-to-date assets. This is a
        non-GAAP financial measure of the level of noninterest income and
        expense.

     The return on average assets for the first quarter of 2006 was 1.45%, down
slightly from the 1.51% for the same period in the prior year. The return on
average equity also experienced a decline.
     The net interest margin declined by 49 basis points. This decrease was due
to rising interest rates. Interest expense has continued to grow at a faster
pace than interest income.

Growth

        The following table shows NBI's key growth indicators:

------------------- ---------------------------- --------------------- ----------------------
</TABLE>

        At March 31, 2006 total assets were $847,956, an increase of $6,458 or
0.77%. If annualized, the growth rate would be approximately 3.1%.
        In order to reduce the compression of the net interest margin,
management has exercised restraint when pricing large denomination time
deposits. This approach has had positive influence on profitability; however, it
has caused lower rates of deposit growth.

--------------------------------------------- ----------------------- --------------------- ----------------------
</TABLE>

        This data indicates that the level of nonperforming loans has declined,
as has the level of loans past due 90 days or more. Other real estate owned
continues to decline as properties foreclosed upon are sold. Asset quality
remains excellent.

Net Interest Income

        Net interest income for the period ending March 31, 2006 was $7,345, a
decrease of $647 or 8.1%.
        The principal cause of the decline is rising interest rates.
Specifically, the Company's interest-bearing liabilities have repriced upward at
a faster pace than interest-earning assets. During the period the yield on
earning assets rose by 7 basis points, while the cost of interest-bearing
liabilities increased by 56 basis points.

Net Interest Income - Trends and Future Expectations

        During 2005, the Federal Reserve Board initiated a series of interest
rate increases. These increases were designed to restore interest rates to
historically more typical levels and to prevent inflation. Rate increases have
occurred at regular intervals, each at 25 basis points to date.
        Rising energy costs coupled with high levels of government spending are
viewed as inflationary. Government expenditures are expected to remain high as a
result of natural disasters, conflict in the Middle East and new spending
programs such as the prescription drug benefit for senior citizens. The Federal
Reserve Bank may yet raise interest rates to combat inflationary pressures.
However, there is a general expectation that interest rates are at or near their
peak. Once interest rates stabilize, the compression of the net interest margin
should begin to abate which would have a positive effect on the level of net
interest income.
        The general impact of a rising interest rate scenario on the Company's
balance sheet is described on page 15 of the Company's 2005 Form 10K, which is
incorporated by reference in this report.

Interest Expense

        Interest expense for the three months ended March 31, 2006 was $4,238,
an increase of $1,195, or 39.3%, from the same period the prior year. As
previously discussed, rising interest rates have been the major contributor to
this increase.
        During periods of rising interest rates, interest-bearing demand
deposits, and to a lesser degree savings deposits, migrate to higher rate,
longer-term time deposits. Generally, as rates climb, more migration occurs.
Given their re-pricing characteristics, interest-bearing demand deposits readily
respond to any interest rate movement. In other words, increases or decreases in
interest expense can occur quite quickly.

Provision and Allowance for Loan Losses

        The provision for loan losses for the three-month period ended March 31,
2006 was $17, a $173 decrease from the same period ended March 31, 2005. The
ratio of the allowance for loan losses to total loans at the end of the first


19
<PAGE>


three months of 2006 was 1.11%, which compares to 1.16% at the same period last
year. The net charge-off ratio at March 31, 2006 was 0.04%, and it was 0.17% at
March 31, 2005.

        The Company regularly reviews asset quality and re-evaluates the
allowance for loan losses. Reviews are conducted for each of the two bank
subsidiaries, and an appropriate provision and allowance for loan losses is
established for each bank, depending upon factors that are unique to that bank
and the quality of its loan portfolio. Because of the continued excellent
overall quality of the loan portfolio, it is management's judgment that the
decrease in the provision for loan losses is justified and the allowance is
appropriate and adequate. (See "Allowance for Loan Losses" under "Critical
Accounting Policies".)

</TABLE>

        Noninterest income is made up of several categories. Following is a
description of each, as well as the factors that influence each.

        Service charges on deposit accounts consist of a variety of charges
imposed on demand deposits, interest-bearing deposits and savings deposit
accounts. These include, but are not limited to, the following:
        o Demand deposit monthly activity fees
        o Service charges for checks for which there are non-sufficient funds or
          overdraft charges
        o ATM transaction fees
        The principal factors affecting current or future levels of income from
this category are:
        o Internally generated growth
        o Acquisitions of other banks/branches or de novo branches
        o Adjustments to service charge structures

        Service charges on deposits were $815 at March 31, 2006, an increase of
$140 or 20.74%. Of that increase, approximately $135 was due to increases in
fees for overdrafts and returned checks. In early 2005 the Company increased its
charge for each overdrawn item, and the amount of daily maximum charges was
increased.

        Other service charges and fees consist of several categories. The
primary categories are listed below.
        o Fees for the issuance of official checks
        o Safe deposit box rent
        o Income from the sale of customer checks
        o Income from the sale of credit life and accident and health insurance

       Levels of income derived from other service charges and fees vary. Fees
for the issuance of official checks and customer check sales tend to grow as
the existing franchise grows and as new offices are added. Fee schedules, while
subject to change, generally do not by themselves yield a significant increase
in income when they change. The most significant growth in safe deposit box
rent also comes with an expansion of offices. Safe deposit box fee schedules,
which are already at competitive levels, are occasionally adjusted. Income
derived from the sale of credit life insurance and accident and health
insurance varies with loan volume.

<PAGE>

       Other service charges and fees at March 31, 2006 were $109, as compared
with $87 for the same period the prior year. Of the $22 increase, approximately
$10 was due to increases in fees associated with cashing income tax refund
checks. Another $5 came from increased fees for letters of credit. The
remainder of the increase were in the safe deposit box, and credit life
insurance categories.

        Credit card fees consist of three types of revenues.
        o Credit card transaction fees
        o Debit card transaction fees
        o Merchant fees

       In all three cases volume is critical to growth in income. For debit and
credit cards the number of accounts, whether obtained from internal growth or
by acquisition, is the key factor. Merchant fees also depend on the number of
merchants in the Company's program, as well as the type of business and the
level of transaction discounts associated with them.
       Credit card fees increased by $30 or 6.07% when March 31, 2006 and March
31, 2005 are compared. The increase was attributable to volume.

       Trust income is somewhat dependent upon market conditions and the number
of estate accounts being handled at any given point in time. Financial market
conditions, which affect the value of trust assets managed, can vary, leading
to fluctuations in the related income. Over the past few years and into 2006,
the financial markets have experienced a degree of volatility. Income from
estates is also unpredictable. Trust income for the first three months of 2006
was $380, a decrease of $28 from the previous year. The decline was the result
of fluctuations in income derived from the settlement of estates.

       Other income is used for types of income that cannot be classified with
other categories of noninterest income. The category includes such things as:
        o Net gains on the sale of fixed assets
        o Rent on foreclosed property
        o Income from cash value life insurance
        o Other infrequent or minor forms of income
        o Revenue from investment and insurance sales

        Given the nature of the items included in this category, trends or
patterns are not identifiable. Other income increased $130 when March 31, 2006
and March 31, 2005 are compared. Of the $130 change, approximately $112 was
attributable to increases in cash value associated with bank owned life
insurance policies.

        Realized net gains and losses on securities include write-downs in
certain investments in limited liability companies (LLC's) of which the Company
is part owner, as well as sales, maturities and calls of securities.
        Realized gains and losses were ($36) for the period ended March 31,
2006. The majority of this loss was attributable to write-downs in investments
in limited liability companies (LLC's).

----------------------------- --------------------------- -------------------------- ---------------------------
</TABLE>

       Noninterest expense includes several categories. A brief description of
the factors that affect each follows.

       In addition to employee salaries, the salaries and benefits expense
category includes the costs of employment taxes and employee fringe benefits.
Certain of these are:
        o Health insurance
        o Employee life insurance
        o Dental insurance
        o Executive compensation plans (1)
        o Qualified Pension plans (1)
        o Supplemental retirement plan (salary continuation agreements)
        o Employer FICA
        o Unemployment taxes
        (1) See the 2005 Form 10-K and the Proxy Statement for the 2006 Annual
        Meeting of Stockholders for further information.
        Salaries and employee benefits expense was $2,911 at March 31, 2006, an
increase of $49 or 1.71% when compared with the same period in 2005. Included in
the increase is an $83 expense associated with a supplemental retirement plan
that provides for salary continuation agreements with selected officers of the
Company and its affiliates. This expense was offset by income from bank owned
life insurance on the plan participants. (See the discussion of "Other Income".)
The Company employed 283 fulltime equivalent employees at March 31, 2006 and 274
at March 31, 2005.

        Occupancy costs include such items as depreciation expense, maintenance
of the properties, repairs and real estate taxes. At March 31, 2006, occupancy
and furniture and fixture expense was $533, an increase of $54 or 11.27% over
the end of the first quarter last year. In anticipation of the planned merger of
its NBB and BTC affiliates, the Company accrued $35 for the cost of new signage
that will be required at the time of the merger, and this expense accounts for
the majority of the increase in the occupancy, furniture and fixtures category.

        Data processing and ATM expense decreased by $166 when compared to March
31, 2005. A decline in maintenance cost of approximately $93 and a decrease in
conversion expenses of $58 account for most of the decrease.

        Credit card processing includes costs associated with the processing of
credit cards, debit cards and merchant transactions. These expenses are related
to credit card income previously discussed in "Noninterest Income", and the
comments in that section are applicable. Credit card processing expense was $413
for the three months ended March 31, 2006, an increase of $37 from the same
period in 2005. Volume accounted for the increase.

        Intangible expense is influenced by acquisitions, amortization schedules
and impairment testing depending on the nature of the intangible. Core deposit
intangibles are amortized while goodwill is subject to testing for impairment.
Both generally increase with acquisitions. Intangibles amortization expense at
March 31, 2006 was $284, an increase of $18 over the same period the previous
year. The increase was associated with the acquisition of two branches acquired
in February 2005.

        Net cost of other real estate owned consists of losses on disposal,
repairs, write-downs and other foreclosure costs. Net costs of other real estate
owned was down $94 when compared to the first quarter of last year. This
category can fluctuate substantially depending on the number of properties on
hand, the gains or losses on sale and the amount of write-downs.

        Other operating expenses include all other forms of expense not
classified elsewhere in the Company's statement of income. Included in this
category are such items as stationery and supplies, franchise taxes,
contributions, telephone, postage and other operating costs. Other operating
expenses for the first quarter of 2006 were $1,043, down $88 from the same
period in the prior year.

Other borrowings                                   163                    705
Shareholders' equity                           $93,419                $90,470

Loans

        The volume of mortgage loans held for sale is directly related to
interest rate levels. Activity generally peaks during periods of low interest
rates, declining as interest rates rise. Period-end balances are not indicative
of volume, as loans are constantly being originated and sold. The balance shown
at period-end reflects only loans held by NBB for which there are purchase
commitments from investors, but which have not yet been funded. At March 31,
2006 there was approximately $3,898 in outstanding commitments to extend
mortgage loans.
        Construction loans were $27,290 at March 31, 2006 and $27,116 at
December 31, 2005, an increase of $174. This category tends to fluctuate because
of demand and with the seasons. Demand also may vary because of economic
conditions. Completion of construction projects generally occurs within one
year, at which time permanent financing through one of the Company's banking
affiliates or another lender is obtained. Loans for which the Company retains
permanent financing move into the commercial and industrial loan or mortgage
loan categories.
        Real estate loans at March 31, 2006 were $117,326, which represents a
decrease of $95 from December 31, 2005. Loans in this category are for
one-to-four family housing and are loans the banking affiliates elected to
retain rather than to sell on the secondary market.
        Commercial and industrial loans were $264,300 at March 31, 2006, an
increase of $151 from December 31, 2005. Included in this category are loans for
working capital, equipment, commercial real estate and other loans for business
needs. See Note 15 of the Company's 2005 Form 10-K for information related to
"Concentrations of Credit".

<PAGE>

        Loans to individuals decreased by $2,997 when March 31, 2006 is compared
to December 31, 2005.
        Total deposits at March 31, 2006 increased by $3,573 from December 31,
2005. Noninterest-bearing demand deposits increased by $5,450 when March 31,
2006 is compared to December 31, 2005. During the same period, interest-bearing
demand deposits decreased by $371, and time deposits decreased by $2,211.

Liquidity and Capital Resources

        Net cash provided by operating activities was $3,611 for the period
ended March 31, 2006, which compares to $3,793 for the same period the previous
year.
        Net cash used in investing activities was $8,541 for the period ended
March 31, 2006, and $20,365 used for the period ended March 31, 2005. Net cash
provided by financing activities was $3,085 for the period ending March 31,
2006.
        Management is unaware of any commitment that would have a material and
adverse effect on liquidity at March 31, 2006.
        Total shareholders' equity grew by $2,321 from December 31, 2005 to
March 31, 2006. Earnings and the changes in unrealized gains and losses for
securities available for sale accounted for the net increase. During the first
three months of 2006, the Company repurchased 10,700 shares of its own stock for
approximately $255 at an average price of $23.81 (excluding broker commission).
The Tier I and Tier II risk-based capital ratios at March 31, 2006 were 13.61%
and 14.55%, respectively. The Company's leverage capital ratio was 9.64%

        As shown in the above table, the Company is liability sensitive. In
other words, the Company's interest-bearing liabilities reprice and/or mature at
a faster rate than its interest-earning assets. During periods of rising
interest rates, such as we have recently experienced, this causes the Company's
net interest margin to decrease. This in turn has a negative impact on overall
profitability.

Derivatives and Off Balance Sheet Items

        The Company is not a party to derivative financial instruments with
off-balance sheet risks, such as futures, forwards, swaps and options. The
Company is a party to financial instruments with off-balance sheet risks, such
as commitments to extend credit, standby letters of credit, and recourse
obligations in the normal course of business, to meet the financing needs of its
customers. Management does not plan any future involvement in high- risk
derivative products.
        The Company's banking affiliates extend lines of credit to their
customers in the normal course of business. Amounts drawn upon these lines vary
at any given time depending on the business needs of the customers.
        Standby letters of credit are also issued to the banks' customers. There
are two types of standby letters of credit. The first is a guarantee of payment
to facilitate customer purchases. The second type is a performance letter of
credit that guarantees a payment if the customer fails to perform a specific
obligation.
        While it would be possible for customers to draw in full on approved
lines of credit and letters of credit, historically this has not occurred. In
the event of a sudden and substantial draw on these lines, the Company has its
own lines of credit on which it could draw funds. Sale of the loans would also
be an option.
        The Company also sells mortgages on the secondary market for which there
are recourse agreements should the borrower default.
        During the first three months of 2006, there have been no significant or
unusual changes in this area.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

        The Company considers interest rate risk to be a significant market risk
and has systems in place to measure the exposure of net interest income to
adverse movement in interest rates. Interest rate shock analyses provides
management with an indication of potential economic loss due to future rate
changes. There have not been any changes which would significantly alter the
results disclosed as of December 31, 2005 in the Company's Form 10-K. (See
"Interest Rate Sensitivity" above.)

Item 4.   Controls and Procedures

        Under the supervision and with the participation of management,
including the Company's principal executive officer and principal financial
officer, the Company has conducted an evaluation of the effectiveness of the
design and operation of its disclosure controls and procedures as of March 31,
2006. Based on that evaluation, the Company's principal executive officer and
principal financial officer have concluded that these controls and procedures
are effective to give reasonable assurance in alerting them in a timely fashion
to material information relating to the Company that is required to be included
in the reports the Company files under the Act. There were no changes in the
Company's internal controls over financial reporting during the period covered
by this report that have materially affected, or are reasonably likely to
materially affect, the Company's internal control over financial reporting.
        Disclosure controls and procedures are the Company's controls and
procedures that are designed to ensure that information required to be disclosed
by the Company in the reports it files or submits under the Exchange Act is
accumulated and communicated to allow timely decisions regarding its required
disclosure. The Company believes that a controls system, no matter how well
designed and operated, cannot provide absolute assurance that all control issues
have been detected.
