    <TD>The preparation of financial statements in conformity with GAAP requires management to make
estimates and assumptions that affect the amounts reported in the condensed 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, legal accruals, the allowance for doubtful accounts,
self-insurance, warranty accruals and postretirement benefit obligations.</TD>

    <TD>In the first quarter of fiscal 2006, we adopted Statement of Financial Accounting Standards
No.&nbsp;123 (revised 2004), &#147;<I>Share-Based Payment</I>&#148; (&#147;SFAS No.&nbsp;123R&#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 and any unearned or deferred compensation
(contra-equity accounts) related to awards prior to adoption be eliminated against the
appropriate equity accounts. 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 third quarter of 2006 was not material.</TD>

    <TD>Under SFAS No.&nbsp;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
No.&nbsp;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>In July&nbsp;2006, the Financial Accounting Standards Board (&#147;FASB&#148;) issued Interpretation No.&nbsp;48,
<I>&#147;Accounting for Uncertainty in Income Taxes&#148; </I>(&#147;FIN 48&#148;). FIN 48 clarifies the accounting for
uncertainty in income taxes recognized in the Company&#146;s financial statements in accordance
with FASB Statement No.&nbsp;109, <I>&#147;Accounting for Income Taxes.&#148; </I>FIN 48 also prescribes a
recognition threshold and measurement attribute for the financial statement recognition and
measurement of a tax position taken or expected to be taken in a tax return and provides
guidance on derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. The provisions of FIN 48 are to be applied to all tax
positions upon initial adoption of this standard. Only tax positions that meet the &#147;more
likely than not&#148; recognition threshold at the effective date may be recognized or continue to
be recognized upon adoption of FIN 48. FIN 48 is effective for our fiscal year beginning
October&nbsp;1, 2007. The Company is currently evaluating the impact of adopting FIN 48.</TD>

    <TD>On July&nbsp;14, 2006, we acquired certain assets and hired the service and administrative
employees of an electrical services company in Louisiana for approximately $1.5&nbsp;million. The
purchase price was paid from existing cash and short-term marketable securities. This
acquisition allows us to extend sales and service to the Eastern Gulf Coast Region. As this
acquisition is not material to the consolidated financial results or financial position of
the Company, no additional disclosure is included in these Notes to Condensed Consolidated
Financial Statements. Approximately $1.5&nbsp;million of the purchase price is included in
intangible assets in the Condensed Consolidated Balance Sheets. The
purchase price resulted primarily in additional intangible assets and
as a result such amounts are subject to further adjustment as
information becomes available.</TD>

    <TD>On July&nbsp;4, 2005, we acquired selected assets and assumed certain operating liabilities and
contracts of Switchgear &#038; Instrumentation Limited. 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 F herein). The results of operations of
S&#038;I are included in our Condensed Consolidated Financial Statements from July&nbsp;4, 2005. The
Condensed Consolidated Balance Sheets include an allocation of the purchase price to the
assets acquired and liabilities assumed based on estimates of fair value.</TD>

the computation because the effect of the options was not dilutive as their exercise prices

    <TD>On June&nbsp;29, 2005, we entered into a new senior credit agreement (&#147;Credit Agreement&#148;) with a
major domestic bank and certain other financial institutions which replaced our existing
revolving line of credit. The Credit Agreement also replaced an existing letter of credit
facility used to guarantee payment of our existing loan agreement that was funded with
proceeds from tax-exempt industrial development revenue bonds. This expanded credit facility
was put in place to partially fund the acquisition of and provide working capital support for

Revolver&#148;), 2) &#163;4.0&nbsp;million (pound sterling) (approximately $7.0&nbsp;million) revolving credit
facility (&#147;UK Revolver&#148;) and 3) &#163;6.0&nbsp;million (approximately $10.7&nbsp;million) single advance
term loan (&#147;UK Term Loan&#148;). The Credit Agreement contains customary affirmative and negative
covenants and restricts our ability to pay dividends. In addition, there are various
restrictive covenants pertaining to maintenance of net worth and certain financial ratios.
Obligations are secured by the stock of our subsidiaries. The interest rate for amounts
outstanding under the Credit Agreement is a floating rate based upon LIBOR plus a margin
which can range from 1.25% to 2.25%, as determined by the Company&#146;s consolidated leverage
ratio as defined in the Credit Agreement.</TD>

    <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. 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. At July&nbsp;31, 2006,
approximately $6.4&nbsp;million was outstanding on the bonds and the interest rate is based on
similar types of short-term municipal securities and was 3.73% per annum on July&nbsp;31, 2006.</TD>

owed amounts in accounts receivable and costs and estimated earnings in excess of billings on

    <TD>In July&nbsp;2006, the Compensation Committee of the Board of Directors modified the vesting
requirements for stock options upon retirement. The Committee voted to automatically vest
granted options upon retirement at age 60 with 10&nbsp;years of service or at age 62 regardless of
service. Stock options are vested at retirement and will remain exercisable for the
remaining life of the option. All other terms of stock options remain the same.</TD>

    <TD>In accordance with SFAS No.&nbsp;123R, we recognized approximately $0.9&nbsp;million in non-cash
compensation expense in the third quarter of 2006 related to the modification. This non-cash
expense was recorded in selling, general and administrative expenses in July&nbsp;2006. After the
modification adjustment, there is $1.8&nbsp;million of unrecognized non-cash compensation expense
related to non-vested stock options at July&nbsp;31, 2006. Of the $1.8&nbsp;million unrecognized
compensation expense, $0.5&nbsp;million will be expensed over a revised weighted-average period of
approximately 1.7&nbsp;years. The remaining $1.3&nbsp;million is expected to be recognized over a
weighted-average period of approximately 2.1&nbsp;years. In addition, at July&nbsp;31, 2006, there was
approximately $0.1&nbsp;million of total unrecognized compensation expense related to restricted
stock which is expected to be recognized over a period of less than one year.</TD>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><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 as of July&nbsp;4, 2005. Financial information related to these business
segments is included in Note I of the Notes to Condensed Consolidated Financial Statements.
</DIV>

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Revenue and Gross Profit</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Consolidated revenues increased $37.1&nbsp;million to $104.0&nbsp;million in the third quarter of fiscal 2006
compared to third quarter 2005 revenues of $66.9&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 $13.8&nbsp;million and
$3.0&nbsp;million, all outside the United States (&#147;International&#148;), in the third quarter of fiscal 2006
and 2005, respectively. For the three months ended July&nbsp;31, 2006, domestic revenues increased by
53.4% to $71.7&nbsp;million. Total International revenues were $32.3&nbsp;million in the third quarter of
2006 compared to $20.1&nbsp;million in the same quarter of the prior year. International revenues
increased primarily due to the acquisition of S&#038;I. Gross profit for the third quarter of 2006
increased by approximately $6.5&nbsp;million as a result of improved backlog volume and pricing, coupled
with the acquisition of S&#038;I.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the nine months ended July&nbsp;31, 2006, consolidated revenues increased $112.8&nbsp;million to $286.3
million compared to the nine months ended July&nbsp;31, 2005 of $173.5&nbsp;million. The acquisition of S&#038;I
added revenues of $40.7&nbsp;million and $3.0&nbsp;million, all International, in the first nine months of
fiscal 2006 and 2005, respectively. Domestic revenues for the first nine months of fiscal 2006
were $200.5&nbsp;million compared to $138.0&nbsp;million for the first nine months of fiscal 2005. Total
International revenues were $85.7&nbsp;million for the first nine months of fiscal 2006 compared to
$35.6&nbsp;million for the same period of last year. For the nine months ended July&nbsp;31, 2006,
International revenue accounted for 30% of consolidated revenues compared to 20% for the same
period a year ago; the increase was primarily due to the acquisition of S&#038;I. Gross profit for the
first nine months of fiscal 2006 increased by approximately $26.7&nbsp;million as a result of improved
backlog volume and pricing, coupled with the acquisition of S&#038;I. The increase in gross profit was
partially offset by $0.8&nbsp;million for estimated costs related to the resolution of a specific
product performance issue.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Electrical Power Products</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our Electrical Power Products segment recorded revenues of $96.9&nbsp;million in the third quarter of
2006, which includes revenues of $13.8&nbsp;million from the acquisition of S&#038;I, compared to $58.2
million for the same period of the previous year. During the third quarter of fiscal 2006, revenues
in all our major markets strengthened compared to the same period of the prior year. In the third
quarter of fiscal 2006, revenues from public and private utilities were approximately $28.1
million, an increase of $0.2&nbsp;million compared to the third quarter of fiscal 2005. Revenues from
industrial customers totaled $54.9&nbsp;million in the third quarter of fiscal 2006 compared to $28.7
million in the same period of the prior year. Municipal and transit projects generated revenues of
$14.0&nbsp;million in the third quarter of fiscal 2006 compared to $1.6&nbsp;million in the same period a
year ago.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">For the nine months ended July&nbsp;31, 2006, this segment recorded revenues of $265.4&nbsp;million, which
includes revenues of $40.7&nbsp;million from the acquisition of S&#038;I, compared to $146.4&nbsp;million for the
first nine months of fiscal 2005. Utility revenues totaled $84.5&nbsp;million, an increase of
approximately 19.4% over prior year. Industrial revenues were $151.8&nbsp;million compared to $68.2
million a year ago and revenues from municipal and transit projects totaled $29.0&nbsp;million compared
to $7.4&nbsp;million for the same period of last year.
</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 18.0% in the third quarter of fiscal 2006, compared to 15.8% in the third quarter of fiscal
2005. This increase in gross profit resulted from improved pricing, operating efficiencies
resulting from increased volume, as well as service and replacement projects resulting from the
hurricanes of 2005 along the Gulf Coast Region. Material costs increased approximately $1.6
million in the third quarter of fiscal 2006 compared to the same period a year ago, primarily due
to higher unit prices for copper.

18.6% from 13.9% in the first nine months of fiscal 2005. This increase in gross profit resulted
from improved pricing, operating efficiencies resulting from increased volume, as well as increased
services and replacement projects resulting from the hurricanes of 2005 along the Gulf Coast
Region. Direct material costs increased approximately 1.7%, or $2.4&nbsp;million, during the first nine
months of 2006 compared to the same period a year ago primarily due to higher unit prices for
copper. In addition, incremental production costs of approximately $0.6&nbsp;million were incurred
during the first nine months of fiscal 2005 due to start-up difficulties and inefficiencies with
our recently relocated distribution switch product line.

fiscal 2006 from $8.7&nbsp;million for the same period of the prior year. For the nine months ended
July&nbsp;31, 2006, segment revenues decreased to $20.9&nbsp;million compared to $27.2&nbsp;million in the same
period last year. These decreases in revenue are attributable to a decrease in the proportion of
subcontracted installation activities. As discussed in Note G of the Notes to Condensed
Consolidated Financial Statements, Process Control Systems recorded additional revenue and profit
of $1.5&nbsp;million from the settlement of a claim related to the Central Artery/Tunnel Project in the
third quarter of 2005.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Segment gross profit decreased to $1.7&nbsp;million compared to $3.3&nbsp;million in the third quarter of

mentioned above. Gross profit was negatively impacted by approximately $0.5&nbsp;million and $0.9
million in the third quarter of 2006 and 2005, respectively, primarily due to legal costs incurred
related to the recovery of amounts owed on a previously completed contract. For the nine months
ended July&nbsp;31, 2006, segment gross profit decreased to $5.3&nbsp;million compared to $7.6&nbsp;million in the
same period last year primarily related to the settlement of the claim related to the Central
Artery/Tunnel Project. In addition, gross profit was negatively impacted by approximately $1.1
million and $1.2&nbsp;million for the nine months ended July&nbsp;31, 2006 and 2005, respectively, due to
legal costs incurred related to the recovery of amounts owed on a previously completed contract.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Consolidated selling, general, and administrative expenses increased to 15.1% of revenues in the
third quarter of 2006 compared to 14.8% of revenues in the same period of last year. Selling,
general, and administrative expenses were $15.7&nbsp;million, an increase of $5.8&nbsp;million over the same
period last year, of which the operating activities of S&#038;I accounted for $1.7&nbsp;million of the
increase. In the first quarter of fiscal 2006, we adopted SFAS No.&nbsp;123 (Revised 2004),
<I>&#147;Share-Based Payment&#148; </I>(&#147;SFAS No.&nbsp;123R&#148;), which required us to expense the estimated non-cash
compensation related to stock options. In July&nbsp;2006, we accelerated vesting on stock options of
employees of retirement age. This accelerated vesting resulted in the recognition of an additional
$0.9&nbsp;million of non-cash compensation expense in accordance with SFAS No.&nbsp;123R. The non-cash
compensation expense and the vesting modification related to stock options increased selling,
general, and administrative expenses by approximately $1.1&nbsp;million in the third quarter of fiscal
2006. In addition, we recorded additional sales tax expense of $0.3&nbsp;million due to an unfavorable
outcome from a state audit. The remainder of this increase of $2.7&nbsp;million is primarily
attributable to increased salaries, incentive wages and bonuses which are consistent with the
increase in earnings.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Consolidated selling, general and administrative expenses decreased to 14.9% of revenues in the
first nine months of fiscal 2006 compared to 16.6% of revenues in the same period of last year.
Selling, general and administrative expenses were $42.5&nbsp;million, an increase of $13.8&nbsp;million over
the same period last year, of which the operating activities of S&#038;I accounted for $6.2&nbsp;million of
the increase. For the nine months ended July&nbsp;31, 2006, research and development expenditures were
$3.4&nbsp;million compared to $1.8&nbsp;million in the first nine months of fiscal 2005. The adoption of
SFAS No.&nbsp;123R and the vesting modification increased selling, general, and administrative expenses
by approximately $1.8&nbsp;million in the first nine months of fiscal 2006. Salaries and incentive
wages increased by approximately $2.6&nbsp;million in the first nine months of fiscal 2006 compared to
the first nine months of fiscal 2005. In addition, we recorded additional sales tax expense of
$0.3&nbsp;million due to an unfavorable outcome from a state audit. The remaining increase of $1.3
million is primarily attributable to increased legal and accounting fees and sales and use taxes.

taxes of 43.3% in the third quarter of fiscal 2006 compared to 24.5% in the third quarter of fiscal
2005 and an effective rate of 39.9% in the first nine months of fiscal 2006 compared to a tax
benefit of (259.5%) in the first nine months of fiscal 2005. Our effective tax rate will generally
be lower due to income generated in the United Kingdom which has a lower statutory rate than the
United States; however, the lower statutory rate will be offset by certain expenses that are not
deductible for tax purposes in the United Kingdom, such as amortization of intangible assets.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The tax rate for the third quarter and the nine month period ended July&nbsp;31, 2005 resulted from a
change in estimate on our Extraterritorial Income Exclusion Benefit on the prior year federal tax
return and the reversal of state income tax accruals from previous years due to the expiration of
the statutory limitations. The overall effective tax rate improved as a result of the favorable
tax impact of approximately $0.8&nbsp;million of pretax deductions resulting from the reconciliation of
the income tax provision to the prior year income tax return.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Net Income</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the third quarter of 2006, we generated net income of $1.8&nbsp;million, or $0.16 per diluted share,
compared to $2.1&nbsp;million, or $0.19 per diluted share, in the third quarter of fiscal 2005. For the
nine months ended July&nbsp;31, 2006, we recorded net income of $7.0&nbsp;million, or $0.63 per diluted
share, compared to $0.4&nbsp;million, or $0.04 per diluted share for the first nine months of 2005.
Higher revenues and improved gross profits in our Electrical Power Products business segment,
partially offset by increased selling, general and administrative expenses associated with higher
levels of business activity including the effect of the S&#038;I acquisition, have improved net income
in 2006 compared to the same periods a year ago. These increases were partially offset by the
reduction in net income in 2006 by non-cash compensation expense related to stock options and
additional sales tax expense recorded due to an unfavorable outcome from a state audit.
Additionally, net income in 2005 was increased by the favorable settlement of the Central/Artery
Tunnel Project.

end 2005 and $250.8&nbsp;million at the end of the third quarter one year ago. New orders placed during

net of current maturities, totaled $17.5&nbsp;million at July&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

million) revolving credit agreement in the United Kingdom expiring June&nbsp;2008. As of July&nbsp;31, 2006,
there was &#163;1.9&nbsp;million, or approximately $3.5&nbsp;million, outstanding under the UK Revolver (as
defined in Note F to Condensed Consolidated Financial Statements). No amounts were borrowed on the
US Revolver as of July&nbsp;31, 2006. We were in compliance with all debt covenants as of July&nbsp;31,

in the United States and early in calendar year 2007 at S&#038;I. Cash of $1.5&nbsp;million was also used
for the acquisition of UMS. A year ago, the majority of our capital expenditures were used to

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><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 and into 2007.
Customer inquiries, or requests for proposals have remained strong during the second half of fiscal
2005 and into 2006. One of the positive trends we have experienced is strong new order activity.
New orders in the third quarter of 2006 totaled $122.2&nbsp;million compared to $135.4&nbsp;million in the
same period one year ago. Our new orders in the third quarter of 2005 included our previously
announced $51.0&nbsp;million contract with the Washington Metropolitan Area Transit Authority. We are
cautiously optimistic that we will continue to experience a strong level of bookings throughout
fiscal 2006 and into early 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In our Electrical Power Products segment, new orders in the third quarter of 2006 totaled $120.5
million compared to $128.4&nbsp;million in the same period one year ago. Our new orders in the third
quarter of 2005 included our previously announced $51.0&nbsp;million contract with the Washington
Metropolitan Area Transit Authority. We believe that improved market pricing and increased volume
along with our continued focus on cost containment should result in increased gross margins over
historical trends. Raw material costs such as copper continue to negatively impact our gross
margins; however, we believe raw material prices have become less volatile and their impact on our
costs should be reduced in the future. 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 improved 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 and into 2007 due to increased business activity and the
recent acquisition from GE. 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 align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;3. </B><B><I>Quantitative And Qualitative Disclosures About Market Risk</I></B>
</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. Amounts invested in our foreign operations are translated
into U.S. Dollars at the exchange rate in effect at the end of the period reported. The resulting
translation adjustments are recorded as accumulated other comprehensive income, a component of
stockholders&#146; equity, in our condensed consolidated balance sheets. We believe the exposure to the
effects that fluctuating foreign currencies have on our condensed consolidated results of
operations is limited because the foreign operations primarily invoice customers and collect
obligations in their respective currencies or U.S. Dollars. The Company&#146;s net exposure on its
investment in S&#038;I is offset by the UK Term Loan which is payable in pound sterling. Additionally,
expenses associated with these transactions are generally contracted and paid for in the same local
currencies.
</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. Regarding our various debt instruments outstanding at July&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 approximately $200,000. 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. While improved market prices have allowed us to
offset these cost increases, the long-term nature of our contracts expose us to cost increases
which may negatively impact our profit on a particular contract. Fluctuations in commodity prices
could have a material effect on our future earnings and cash flows.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Item&nbsp;4. </B><B><I>Controls And Procedures</I></B>
</DIV>

<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. During the third quarter of 2006, management replaced its production and
general ledger software at one of its divisions with Oracle. This conversion to Oracle involved
various changes to internal processes and control procedures over financial reporting; however, the
basic internal controls over financial reporting have not materially changed as a result of the
Oracle implementation. 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.

(&#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.</TD>

    <TD>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, it is expected to go to trial in 2006 in Alameda County Superior
Court, State of California. As of July&nbsp;31, 2006, the Company had approximately $1.6
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
