    <TD>The preparation of financial statements in conformity with GAAP requires management to make
estimates and assumptions that affect the amounts reported in the consolidated financial
statements and accompanying footnotes. The amounts we record for insurance claims,
warranties, legal and other contingent liabilities require judgments regarding the amount of
expenses that will ultimately be incurred. We base our estimates on historical experience
and on various other assumptions, as well as the specific circumstances surrounding these
contingent liabilities in evaluating the amount of liability that should be recorded.
Estimates may change as new events occur, additional information becomes available, or
operating environments change. Actual results may differ from our estimates. The most
significant estimates used in our financial statements affect revenue and cost recognition
for construction contracts, the allowance for doubtful accounts, self-insurance, warranty
accruals, and postretirement benefit obligations.</TD>

    <TD>In the first quarter of 2006, we adopted SFAS No.&nbsp;123 (revised 2004), &#147;<I>Share-Based Payment</I>.&#148;
We adopted the new statement using the modified prospective method of adoption, which does
not require restatement of prior periods. The revised standard eliminated the intrinsic
value method of accounting for share-based employee compensation under APB Opinion No.&nbsp;25,
&#147;<I>Accounting for Stock-Based Compensation</I>,&#148; which we previously used (see pro-forma disclosure
of prior period included herein). The revised standard generally requires the recognition of
the cost of employee services for share-based compensation based on the grant date fair value
of the equity or liability instruments issued. The effect of adoption of the new standard in
the first quarter of 2006, related to stock options and restricted stock plans was an
additional expense of $0.4&nbsp;million pretax, or $0.3&nbsp;million after tax ($0.02 per share, basic
and diluted). Also under the new standard, excess income tax benefits related to share-based
compensation expense that must be recognized directly in equity are considered financing
rather than operating cash flow activities. The effect of the adoption of the new standard
on cash flows in the first quarter of 2006 was not material. At January&nbsp;31, 2006, there was
$3.3&nbsp;million of total unrecognized compensation cost related to non-vested stock options.
This compensation is expected to be recognized over a weighted-average period of
approximately 2.3&nbsp;years. In addition, at January&nbsp;31, 2006, there was $0.2&nbsp;million of total
unrecognized compensation cost related to restricted stock. This compensation is expected to
be recognized over a period of less than two years.</TD>

    <TD>Under SFAS 123R, we continue to use the Black-Scholes option pricing model to estimate the
fair value of our stock options. However, we will apply the expanded guidance under SFAS
123R for the development of our assumptions used as inputs for the Black-Scholes option
pricing model for grants issued after November&nbsp;1, 2005. Expected volatility is determined
using historical volatilities based on historical stock prices for a period equal to the
expected term. The expected volatility assumption is adjusted if future volatility is
expected to vary from historical experience. The expected term of options represents the
period of time that options granted are expected to be outstanding and falls between the
option&#146;s vesting and contractual expiration dates. The risk-free interest rate is based on
the yield at the date of grant of a zero-coupon U.S. Treasury bond whose maturity period
equals the option&#146;s expected term.</TD>

    <TD>The 1992 Stock Option Plan, as amended (the &#147;1992 Plan&#148;), permits the Company to grant
to key employees non-qualified options and stock grants, subject to certain conditions and
restrictions as determined by the Compensation Committee of the Board of Directors and
proportionate adjustments in the event of stock dividends, stock splits and similar corporate
transactions. The number of shares available for issuance under the 1992 Plan is 2.7&nbsp;million
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares. There were no stock grants the first quarter of fiscal 2006. Stock options are
granted at an exercise price equal to the fair market value of the common stock on the date
of the grant. Generally, options granted have an expiration date of seven years from the
grant date and vest in increments of 20% per year over a five-year period. Pursuant to the
1992 Plan, option holders who exercise their options and hold the underlying shares of common
stock for five years, vest in a stock grant equal to 20% of the original option shares.
While restricted until the expiration of five years, the stock grant is considered issued at
the date of the stock option exercise and is included in earnings per share.</TD>

    <TD>The 2000 Non-Employee Stock Option Plan, as amended, was adopted for the benefit of members
of the Board of Directors of the Company who, at the time of their service, are not employees
of the Company or any of its affiliates. Annually, each eligible Director who is continuing
to serve as a Director, will receive a grant of an option to purchase 2,000 shares of our
common stock. Stock options granted to the Directors are non-qualified and are granted at an
exercise price equal to the fair market value of the common stock at the date of grant.
Generally, options granted have expiration terms of seven years from the date of grant and
will vest in full one year from the grant date. There will be no further grants awarded
under this plan. The Compensation Committee of the Board of Directors plans to terminate the
2000 Non-Employee Director Stock Option Plan after all outstanding options have been
exercised or have expired.</TD>

    <TD>On July&nbsp;4, 2005, we acquired selected assets and assumed certain operating liabilities and
contracts of Switchgear &#038; Instrumentation Limited. We refer to the acquired business herein
as &#147;S&#038;I.&#148; S&#038;I&#146;s primary manufacturing facility is in the United Kingdom. This acquisition
is part of our overall strategy to increase our international presence. S&#038;I affords us the
opportunity to serve our customers with products covering a wider range of electrical
standards and opens new geographic markets previously closed due to a lack of product
portfolio. The fit, culture and market position of Powell and S&#038;I are favorably comparable
with similar reputations in engineered to order solutions. S&#038;I is a supplier of medium- and
low-voltage switchgear, intelligent motor control systems, and power distribution solutions
to a wide range of process industries, with a focus on oil and gas, petrochemical and other
process-related industries. Total consideration paid for S&#038;I was approximately $18.0&nbsp;million
(excluding expenses of approximately $1.2&nbsp;million). Approximately $10.3&nbsp;million was funded
from existing cash and investments and the balance was provided from the UK Term Loan (as
defined in Note G herein). The results of operations of S&#038;I are included in our Consolidated
Financial Statements from July&nbsp;4, 2005. The Condensed Consolidated Balance Sheets includes
an allocation of the purchase price to the assets acquired and liabilities assumed based on
estimates of fair value.</TD>

    <TD>For the three months ended January&nbsp;31, 2006, options to purchase approximately 24,000
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;shares were excluded from the computation of diluted earnings per share because the options&#146;
exercise prices were greater than the average market price of our common stock. We had a net
loss for the three months ended January&nbsp;31, 2005; accordingly, the inclusion of common stock
equivalents for outstanding stock options would be antidilutive and, therefore the weighted
average shares used to calculate both basic and diluted loss per share are the same.</TD>

otherwise resolved, this claim is scheduled to go to trial in 2006. As of January&nbsp;31, 2006,
the Company had approximately $1.4&nbsp;million recorded in the consolidated balance sheet for
contractually owed amounts in accounts receivable and costs and estimated earnings in excess

    <TD>We borrowed $8.0&nbsp;million in October&nbsp;2001 through a loan agreement funded with proceeds from
tax-exempt industrial development revenue bonds (&#147;Bonds&#148;). These Bonds were issued by the
Illinois Development Finance Authority and were used for the completion of our Northlake,
Illinois facility. Pursuant to the Bond issuance, a reimbursement agreement between the
Company and a major domestic bank required an issuance by the bank of an irrevocable
direct-pay letter of credit (&#147;Bond LC&#148;) to the Bonds&#146; trustee to guarantee payment of the
Bonds&#146; principal and interest when due. The Bond LC periodically changes in amount to equal
the outstanding balance of the Bonds and terminates on October&nbsp;25, 2006. The Bond LC is
subject to both early termination and extension provisions customary to such agreements.
While the Bonds mature in 2021, the reimbursement agreement requires annual redemptions of
$400,000. A sinking fund is used for the redemption of the Bonds. The Bonds bear interest
at a floating rate determined weekly by the Bonds&#146; remarketing agent, which was the
underwriter for the Bonds and is an affiliate of the bank. This interest rate is based on
similar types of short-term municipal securities and was 3.12% per annum on January&nbsp;31, 2006.</TD>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Overview</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We develop, design, manufacture, and service equipment and systems for the management and control
of electrical energy and other critical processes. Headquartered in Houston, Texas, we serve the
transportation, environmental, industrial, and utility industries. Our business operations are
consolidated into two business segments: Electrical Power Products and Process Control Systems.
On July&nbsp;4, 2005, we acquired selected assets and assumed certain operating liabilities and
contracts of Switchgear and Instrumentation Limited in the United Kingdom. The acquired business
is referred to herein as &#147;S&#038;I.&#148; The operating results of S&#038;I are included in our Electrical Power
Products business segment. Financial information related to these business segments is included in
Note H of the Notes to Condensed Consolidated Financial Statements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Results of Operations</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Revenue and Gross Profit</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Consolidated revenues increased $36.1&nbsp;million to $83.8&nbsp;million in the first quarter of fiscal 2006
compared to first quarter 2005 revenues of $47.7&nbsp;million. Revenues increased primarily due to
general market recovery, concerted sales efforts in 2005 aimed at strengthening our backlog and the
acquisition in early July&nbsp;2005 of S&#038;I. The acquisition of S&#038;I added revenues of $12.6&nbsp;million, all
outside the United States, in the first quarter of fiscal 2006. For the three months ended January
31, 2006, domestic revenues increased by 46% to $61.4&nbsp;million. International revenues were $22.4
million in the first quarter 2006 compared to $5.7&nbsp;million in the same quarter of the prior year.
Revenues outside the United States accounted for 27% of consolidated revenues in the first quarter
of fiscal 2006 compared to 12% in the first quarter of fiscal 2005; the increase is primarily due
to the acquisition of S&#038;I.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Electrical Power Products</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our Electrical Power Products segment recorded revenues of $76.6&nbsp;million in the first quarter of
2006, which includes revenues of $12.6&nbsp;million from the acquisition of S&#038;I, compared to $39.8
million for the same time period of the previous year. During the first quarter of fiscal 2006,
revenues in all our major markets strengthened compared to the same period of the prior year. In
the first quarter of fiscal 2006, revenues from public and private utilities were approximately
$22.7&nbsp;million, an increase of $7.4&nbsp;million compared to the first quarter of fiscal 2005. Revenues from industrial customers
totaled $46.9&nbsp;million in the first quarter of fiscal 2006 compared to $20.4&nbsp;million in the same
period of the prior year. Municipal and transit projects generated revenues of $7.0&nbsp;million in the
first quarter of fiscal 2006 compared to $4.0&nbsp;million in the same period a year ago.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The gross profit from the Electrical Power Products segment increased, as a percentage of revenues,
to 17.0% in the first quarter of fiscal 2006, compared to 13.2% in the first quarter of fiscal
2005. Excluding the S&#038;I acquisition, segment gross profit would have been 16.3% in the first
quarter of fiscal 2006. This increase in gross profit resulted from improved pricing and operating
efficiencies resulting from increased volume. Material costs increased approximately $0.2&nbsp;million
in the first quarter of fiscal 2006 compared to the same period a year ago, primarily due to higher
unit prices for copper. Gross profit in the first quarter of 2005 was adversely impacted by
one-time expenses of $0.6&nbsp;million associated with our decision to close our Greenville, Texas and
Elyria, Ohio facilities. These expenses included employee severance, training, and equipment
relocation costs.

2006 compared to 21.8% in the same quarter of the prior year. This increase in gross profit margin
can be attributed to improved job performance on certain projects nearing completion.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Consolidated Selling, General, and Administrative Expenses</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Consolidated selling, general, and administrative expenses decreased to 15.5% of revenues compared
to 20.0% of revenues in the same period of last year. Selling, general, and administrative
expenses were $13.0&nbsp;million, an increase of $3.5&nbsp;million over the same period last year, of which
the S&#038;I acquisition accounted for $2.1&nbsp;million of the increase. In the first quarter of fiscal
2006, we adopted SFAS 123 (Revised 2004), Share-Based Payments which required us to expense the
estimated compensation related to stock options. The adoption of this new standard increased
selling and administrative expense by approximately $0.4&nbsp;million in the first quarter of fiscal
2006. The remainder of this increase of $1.0&nbsp;million is primarily attributable to increased legal
and professional fees, as well as salaries and commissions which are consistent with the increase
in revenues. Additionally, we recorded approximately $0.2&nbsp;million in proceeds from a life
insurance policy in the first quarter of fiscal 2006.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Interest Income and Expense</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Interest expense was approximately $0.3&nbsp;million in the first quarter of fiscal 2006, an increase of
approximately $0.3&nbsp;million compared to the same period in fiscal 2005. This increase in interest
expense is primarily due to additional debt incurred to partially finance the acquisition of S&#038;I
and interest payments to state taxing authorities.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Interest income was $0.3&nbsp;million in both the first quarter of 2006 and 2005.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Provision for Income Taxes</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our provision (benefit)&nbsp;for income taxes reflects an effective tax rate on earnings before income
taxes of 36.9% in the first quarter of fiscal 2006 compared to (39.1%) in the first quarter of
fiscal 2005. Our effective tax rate for the first quarter of fiscal 2006 was reduced as a result
of income generated in the United Kingdom which has a lower statutory rate than the United States.
Our effective tax rate is generally higher than statutory rates because of the effects of certain
expenses that are not deductible for tax purposes, such as amortization of intangible assets. In
addition, adjustments to estimated tax accruals are analyzed and adjusted quarterly as events occur
to warrant such change. Adjustments to tax accruals are a component of the effective tax rate.
During 2004, the American Jobs Creation Act of 2004 was signed into law. The primary effect will
be to permit us to claim a deduction of 3% of earnings related to certain manufacturing and
construction related activities. This deduction may decrease our effective tax rate as a result of
our implementation of this new tax law.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Net Income</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of 2006, we generated net income of $1.1&nbsp;million, or $0.10 per diluted share,
compared to a net loss of $1.4&nbsp;million, or $0.13 per diluted share, in the first quarter of fiscal
2005. Increased gross profits in our Electrical Power Products business segment offset higher
selling, general and administrative expenses.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Backlog</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The order backlog on January&nbsp;31, 2006, was $286.5&nbsp;million, compared to $259.0&nbsp;million at fiscal
year end 2005 and $146.6&nbsp;million at the end of the first quarter one year ago. New orders placed
during the first quarter of 2006 totaled $111.3&nbsp;million compared to $60.1&nbsp;million in the same
period one year ago.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Working capital was $106.4&nbsp;million at January&nbsp;31, 2006, compared to $103.4&nbsp;million at October&nbsp;31,
2005. As of January&nbsp;31, 2006, current assets exceeded current liabilities by 2.7 times and our
debt to capitalization ratio was 12.8%.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As of January&nbsp;31, 2006, we had cash, cash equivalents, and marketable securities of $27.0&nbsp;million
compared to $33.0&nbsp;million as of October&nbsp;31, 2005. Long-term debt and capital lease obligations,
net of current maturities, totaled $18.8&nbsp;million at January&nbsp;31, 2006, compared to $19.4&nbsp;million at
October&nbsp;31, 2005. In addition to our long-term debt, we have a $22.0&nbsp;million revolving credit
agreement in the United States and &#163;4.0&nbsp;million (approximately $7.0&nbsp;million) revolving credit
agreement in the United Kingdom expiring June&nbsp;2008. As of January&nbsp;31, 2006, there was &#163;2.4
million, or approximately $4.2&nbsp;million, outstanding under the UK revolver. No amounts were
borrowed on the US Revolver as of January&nbsp;31, 2006. We were in compliance with all debt covenants
as of January&nbsp;31, 2006.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the three months ended January&nbsp;31, 2006, and 2005, cash used in operating activities was $4.9
million and $12.0&nbsp;million, respectively. This reduction in cash was principally used to fund
growth in inventories and costs related to projects which cannot be billed under the contract
terms.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><I>Investing Activities</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash used for the purchase of property, plant, and equipment during the three months ended January
31, 2006, was $1.2&nbsp;million compared to $1.5&nbsp;million for the same period of the prior year. The
majority of our 2006 capital expenditures were used to implement our new ERP system which is
expected to be completed by the end of fiscal 2006. A year ago, the majority of our capital
expenditures were used to improve our capabilities to manufacture switchgear and electrical power
control rooms.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Cash used to purchase short-term auction rate securities during the three months ended January&nbsp;31,

$0.1&nbsp;million in the same period a year ago. The primary source of cash from financing activities
in both periods was proceeds from the exercise of stock options.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Outlook</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We expect our principal markets to remain steady throughout the balance of 2006. Customer
inquiries, or requests for proposals have steadily strengthened during the second half of fiscal
2005 and on into 2006. One of the positive trends we have experienced is an increase in new order
activity. New orders in the first quarter of 2006 totaled $111.3&nbsp;million compared to $60.1&nbsp;million
in the same period one year ago. We are cautiously optimistic that we will continue to experience
a strong level of bookings throughout fiscal 2006.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In our Electrical Power Products segment, new orders in the first quarter of 2006 totaled $109.0
million compared to $55.5&nbsp;million in the same period one year ago. We believe that our increased
volume and continued focus on cost containment should reduce the impact of increased raw material
costs such as copper and aluminum. Although our Process Control Systems segment continues to
experience soft market conditions, we anticipate increased funding for municipal projects will be
available as general economic conditions strengthen. We believe we are well-positioned to take
advantage of improving economic conditions.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We anticipate that we may need to continue to reinvest a portion of our cash in operating working
capital for the remainder of fiscal 2006. Working capital needs are anticipated to increase with
growing levels of business activity. We believe that working capital, borrowing capabilities, and
cash generated from operations will be sufficient to finance the anticipated operational
activities, capital improvements, debt repayments, and possible future acquisitions for the
foreseeable future.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are exposed to certain market risks arising from transactions we have entered into in the normal
course of business. These risks primarily relate to fluctuations in interest rates, foreign
exchange rates and commodity prices.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are subject to market risk resulting from changes in interest rates related to our outstanding
debt and investments in marketable debt securities. Regarding our various debt instruments
outstanding at January&nbsp;31, 2006, and October&nbsp;31, 2005, a 100 basis point increase in interest rates
would result in a total annual increase in interest expense of less than $200,000. Our investments
in marketable debt securities are carried at fair value on the consolidated balance sheet, with
unrealized gains and losses reported in other comprehensive income. Changes in interest rates will
affect the fair value of the marketable securities as reported. While we do not currently have any
derivative contracts to hedge our exposure to interest rate risk, we have in the past and may in
the future enter into such contracts. Overall, we believe that changes in interest rates will not
have a material near-term impact on our future earnings or cash flows. During each of the past
three years, we have not experienced a significant effect on our business due to changes in
interest rates.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We are subject to market risk from fluctuating market prices of certain raw materials. While such
materials are typically available from numerous suppliers, commodity raw materials are subject to
price fluctuations. We attempt to pass along such commodity price increases to our customers on a
contract-by-contract basis to avoid profit margin erosion. While we may do so in the future, we
have not entered into any derivative contracts to hedge our exposure to commodity risk in fiscal
years 2006 or 2005. We continue to experience significant price pressures with some of our key raw
materials. Competitive market pressures limited our ability to pass these cost increases to our
customers, thus eroding our earnings in 2005 and the first three months of fiscal 2006.
Fluctuations in commodity prices may have a material near-term effect on our future earnings and
cash flows.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Management, with the participation of our Chief Executive Officer (&#147;CEO&#148;) and Chief Financial
Officer (&#147;CFO&#148;), has evaluated the effectiveness of our disclosure controls and procedures (as
defined in Rules&nbsp;13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) as of
the end of the period covered by this report. Based on such evaluation, our CEO and CFO have each
concluded that as of the end of such period, our disclosure controls and procedures were effective
to ensure that information required to be disclosed by us in reports that we file or submit under
the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported
within the time periods specified in the Securities and Exchange Commission&#146;s rules and forms and
that such information is accumulated and communicated to our management, including the CEO and CFO,
as appropriate, to allow timely decisions regarding required disclosures.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We also maintain a system of internal accounting controls that are designed to provide reasonable
assurance that our books and records accurately reflect our transactions and that our policies and
procedures are followed. There have not been any changes in our internal control over financial
reporting (as such term is defined in Rules&nbsp;13a-15(f) and 15d-15(f) under the Securities Exchange
Act of 1934, as amended) during the fiscal quarter to which this report relates that have
materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

</DIV>



<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%">The Company previously entered into a construction joint venture agreement to
supply, install, and commission a Supervisory Control and Data Acquisition System
(&#147;SCADA&#148;) to monitor and control the distribution and delivery of fresh water to the
City and County of San Francisco Public Utility Commission (&#147;Commission&#148;). The project
was substantially completed and has been performing to the satisfaction of the
Commission. However, various factors outside of the control of the Company and its
joint venture partner caused numerous changes and additions to the work that in turn
delayed the completion of the project. The Commission has withheld liquidated damages
and earned contract payments from the joint venture. The Company has made claims
against the Commission for various matters including compensation for extra work and
delay to the project.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%">The Company is currently pursuing the recovery of amounts owed under the contract, as
well as legal and other costs incurred to prosecute its claim. Unless this matter is
otherwise resolved, this claim is scheduled to go to trial in 2006. As of January&nbsp;31,
2006, the Company had approximately $1.4&nbsp;million recorded in the consolidated balance
sheet for contractually owed amounts in accounts receivable and costs and estimated
earnings in excess of billings on uncompleted contracts related to its portion of this
contract. Consistent with Company policy, only costs of directed change orders have
been recorded by the Company. No amounts have been recorded by the Company related to
the Company&#146;s claims and counterclaims alleging breach of the agreement. Although a
failure to recover the amounts recorded could have a material adverse effect on the
Company&#146;s results of operations, the Company believes that, under the circumstances and
on the basis of information now available, an unfavorable outcome is unlikely.
