</DIV>

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

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Powell Industries, Inc. (&#147;we,&#148; &#147;us,&#148; &#147;our,&#148; &#147;Powell&#148; or the &#147;Company&#148;) was incorporated in the
state of Delaware in 2004 as a successor to a Nevada company incorporated in 1968. The Nevada
corporation was the successor to a company founded by William E. Powell in 1947, which merged into
the Company in 1977. Our major subsidiaries, all of which are wholly-owned, include: Powell
Electrical Systems, Inc.; Transdyn, Inc.; Powell Industries International, Inc.; Switchgear &#038;
Instrumentation Limited and Switchgear &#038; Instrumentation Properties Limited.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We develop, design, manufacture and service custom engineered-to-order equipment and systems for
the management and control of electrical energy and other critical processes. Headquartered in
Houston, Texas, we serve the transportation, environmental, energy, industrial and utility
industries.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;<I>Basis of Presentation</I>

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed consolidated financial statements include the accounts of Powell and its
wholly-owned subsidiaries. The financial position and results of operation of our Singapore joint
venture, in which we hold a majority ownership, have also been consolidated. As a result of this
consolidation, we record minority interest on our balance sheet for our joint venture partner&#146;s
share of the equity in the joint venture. All significant intercompany accounts and transactions
have been eliminated in consolidation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed consolidated financial statements have been prepared pursuant to the
rules of the Securities and Exchange Commission (&#147;SEC&#148;). Certain information and footnote
disclosures, normally included in annual financial statements prepared in accordance with
accounting principles generally accepted in the United States, have been condensed or omitted
pursuant to those rules and regulations. Powell believes that the disclosures made are adequate to
make the information presented not misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to fairly state the financial position,
results of operations and cash flows with respect to the interim consolidated financial statements
have been included. The results of operations for the interim periods are not necessarily
indicative of the results for the entire fiscal year. The year-end balance sheet data was derived
from audited financial statements, but does not include all disclosures required by accounting
principles generally accepted in the United States of America.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">These unaudited condensed financial statements should be read in conjunction with the audited
consolidated financial statements and notes thereto of Powell and its subsidiaries included in
Powell&#146;s Annual Report on Form 10-K for the year ended September&nbsp;30, 2007, which was filed with the
SEC on December&nbsp;7, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;<I>Use of Estimates</I>

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The preparation of financial statements in conformity with accounting principles generally accepted
in the United States requires management to make estimates and assumptions that affect the amounts
reported in the condensed consolidated financial statements and accompanying footnotes. The amounts
recorded for insurance claims, warranties, legal, income taxes 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 the Company&#146;s financial statements affect revenue and cost
recognition for construction contracts, the allowance for doubtful accounts, self-insurance,
warranty accruals, income taxes and postretirement benefit obligations.

U.S. Dollar have been translated into U.S. Dollars in accordance with Statement of Financial

operations are translated into U.S. Dollars using period-end exchange rates and all revenues and

(&#147;SFAS No.&nbsp;123R&#148;), we use the Black-Scholes option pricing model to estimate the fair value of our
stock options. We 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.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Company uses an estimated annual effective income tax rate in recording its quarterly provision
for income taxes in the various jurisdictions in which the Company operates. Statutory tax rate
changes and other significant or unusual discrete items are recognized in the quarter in which they
occur.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Company adopted the provisions of Financial Accounting Standards Board (&#147;FASB&#148;) Interpretation
No.&nbsp;48, <I>Accounting for Uncertainty in Income Taxes &#151; an Interpretation of FASB Statement No.&nbsp;109</I>,
(&#147;FIN 48&#148;) on October&nbsp;1, 2007. FIN 48 addresses the determination of whether tax benefits claimed
or expected to be claimed on a tax return should be recorded in the financial statements. Under
FIN 48, the Company may recognize the tax benefit from uncertain tax positions only if it is at
least more likely than not that the tax position will be sustained on examination by the taxing
authorities, based on the technical merits of the position. The tax benefits recognized in the
financial statements from such a position should be measured based on the largest benefit that has
a greater than fifty percent likelihood of being realized upon settlement with the taxing
authorities. FIN 48 also provides guidance on derecognition, classification, interest and
penalties on income taxes, accounting in interim periods and requires increased disclosures.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Upon adoption of FIN 48, the Company recorded a $0.3&nbsp;million increase in its tax reserves, an
offsetting decrease of $0.2&nbsp;million to retained earnings for uncertain tax positions and an
increase in deferred income tax assets of $0.1&nbsp;million. As of the adoption date, the Company had
total tax reserves of approximately $1.2&nbsp;million. This reserve includes an estimate of potential
interest and penalties on estimated liabilities for uncertain tax positions, which are recorded as
components of income tax expense, in the amount of $0.4&nbsp;million as of October&nbsp;1, 2007. Subsequent
to adoption, no significant changes were made to the Company&#146;s tax reserve balances during the
first quarter of fiscal 2008.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Company&#146;s continuing policy is to recognize interest and penalties related to income tax
matters as tax expense. The amount of interest and penalty expense recorded for the three months
ended December&nbsp;31, 2007 was not material.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There was no material change in the net amount of unrecognized tax benefits in the first quarter of
fiscal 2008. Management believes that it is reasonably possible that within the next 12&nbsp;months the
total unrecognized tax benefits will decrease by approximately 35% due to the expiration of certain
statutes of limitations in various state and local jurisdictions.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On December&nbsp;14, 2007, we amended our existing credit agreement (&#147;Amended Credit Agreement&#148;) with a
major domestic bank and certain other financial institutions. This amendment to our credit facility
was made to expand our US borrowing capacity by $16.5&nbsp;million to provide additional working capital
support for the Company. The Amended Credit Agreement extended the expiration date to December&nbsp;31,
2011.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Amended Credit Agreement provides for a 1) $58.5&nbsp;million revolving credit facility (&#147;US
Revolver&#148;), 2) &#163;4.0&nbsp;million (pound sterling) (approximately $8.0&nbsp;million) revolving credit facility
(&#147;UK Revolver&#148;) and 3) &#163;6.0&nbsp;million (approximately $12.0&nbsp;million) single advance term loan (&#147;UK
Term Loan&#148;). The Amended Credit Agreement contains certain covenants with respect to minimum
earnings (as defined), maximum capital expenditures, minimum tangible net worth and restrictions on
our ability to pay dividends. Obligations are secured by the stock of our subsidiaries. The
interest rate for amounts outstanding under the Amended Credit Agreement is a floating rate based
upon LIBOR plus a margin which can range from 0% to 1%, as determined by the Company&#146;s consolidated
leverage ratio as defined within the Amended Credit Agreement. Expenses associated with the
issuance of the original credit agreement are classified as deferred loan costs, totaled $576,000
and are being amortized as a non-cash charge to interest expense.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The US Revolver and the UK Revolver provide for the issuance of letters of credit which would
reduce the amounts which may be borrowed under the respective revolvers. The amount available under
this agreement was reduced by $15.8&nbsp;million for our outstanding letters of credit at December&nbsp;31,
2007. There was &#163;2.3&nbsp;million, or approximately $4.6&nbsp;million, outstanding under the UK Revolver and
$17.5&nbsp;million outstanding under the US Revolver as of December&nbsp;31, 2007. Amounts available under
the US Revolver and the UK Revolver were approximately $25.2&nbsp;million and $3.4&nbsp;million,
respectively, at December&nbsp;31, 2007. The US Revolver and the UK Revolver expire on December&nbsp;31,
2011.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The UK Term Loan provided &#163;6.0&nbsp;million, or approximately $12.0&nbsp;million, for financing the
acquisition of Switchgear &#038; Instrumentation Limited. Approximately &#163;5.0&nbsp;million, or approximately
$10.0&nbsp;million, of this facility was used to finance the portion of the purchase price of Switchgear
&#038; Instrumentation Limited that was denominated in pounds sterling. The remaining &#163;1.0&nbsp;million, or
approximately $2.0&nbsp;million, was utilized as the initial working capital for the surviving business
of Switchgear &#038; Instrumentation Limited that we operate (referred to as &#147;S&#038;I&#148;). Quarterly
installments of &#163;300,000, or approximately $599,000, began

million, was outstanding on the UK Term Loan. The interest rate for amounts outstanding under the
UK Term Loan is a floating rate based upon LIBOR plus a margin which can range from 0% to 1% as

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In connection with the acquisition of the Power/Vac&#174; product line, $8.5&nbsp;million of the total
purchase price of $32.0&nbsp;million was paid to GE at closing on August&nbsp;7, 2006. The remaining balance
of the purchase price of $23.5&nbsp;million is payable in four installments every 10&nbsp;months over the
next 40&nbsp;months from the acquisition date. The deferred installments result in a discounted note
payable of approximately $15.1&nbsp;million at December&nbsp;31, 2007, based on an assumed discount rate of
6.6%. The current portion of this deferred acquisition payable is $5.6&nbsp;million and is included in
the current portion of long-term debt.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">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
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 that
commenced on October&nbsp;25, 2002. A sinking fund is used for the redemption of the Bonds. At December
31, 2007, the balance in the sinking fund was approximately $127,000 and was recorded in cash and
cash equivalents. 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 was 3.58% per annum on December&nbsp;31, 2007.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Certain customers require us to post a bank letter of credit guarantee or performance bonds issued
by a surety. These guarantees and performance bonds assure our customers that we will perform under
terms of our contracts with associated vendors and subcontractors. In the event of default, the
customer may demand payment from the bank under a letter of credit or performance by the surety
under a performance bond. To date, there have been no significant expenses related to either for
the periods reported. We were contingently liable for secured and unsecured letters of credit of
$28.5&nbsp;million as of December&nbsp;31, 2007. We also had performance bonds totaling approximately $132.6
million that were outstanding at December&nbsp;31, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In March&nbsp;2007, we renewed and amended our facility agreement (&#147;Facility Agreement&#148;) with a large
international bank. The Facility Agreement provides S&#038;I with 1) &#163;10.0&nbsp;million in bonds
(approximately $20.0&nbsp;million), 2) &#163;2.5&nbsp;million of forward exchange contracts and currency options
(approximately $5.0&nbsp;million) and 3) the issuance of bonds and entering into forward exchange
contracts and currency options. At December&nbsp;31, 2007, we had outstanding a total of &#163;5.9&nbsp;million,

course of business which, in general, are subject to uncertainties and the outcomes are not

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

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">Despite attempts at mediation, the parties could not resolve their dispute, and a jury trial
commenced in December&nbsp;2006. On May&nbsp;1, 2007, the jury delivered its verdict in favor of the joint
venture, of which the Company is the managing partner, and determined that the Commission had
breached its contract with the joint venture. In accordance with court procedures, the court is currently reviewing other pending
motions, and the final judgment has not been entered. The jury&#146;s verdict is also subject to appeal.
However, based upon the jury&#146;s verdict and the court&#146;s opinion, we anticipate that we will be able
to recover the approximately $1.9&nbsp;million recorded in the consolidated balance sheet at December
31, 2007.

fair value of $31.86 per RSU to certain officers and key employees. The fair value of the RSUs was
based on the closing price of the Company&#146;s common stock as reported on the Nasdaq Global Market on
February&nbsp;23, 2007, which was the date stockholders approved our 2006 Equity Compensation Plan. The
actual amount of RSUs earned will be based on the level of performance achieved relative to
established goals for the remaining two and three year performance cycles which began October&nbsp;1,
2006, and range from 0% to 150% of the target RSUs granted. The remaining vesting period ranges
from two to three years. The performance goal is based on cumulative earnings per share over the
two and three year performance cycles. The RSUs do not have voting rights of common stock and the
shares of common stock underlying the RSUs are not considered issued and outstanding.
Approximately 21,000 of the RSUs granted in October&nbsp;2006 expired as performance targets were not
met.

<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 custom engineered-to-order equipment and systems for
the management and control of electrical energy and other critical processes. Headquartered in
Houston, Texas, we serve the transportation, environmental, energy, industrial and utility
industries. Our business operations are consolidated into two business segments: Electrical Power
Products and Process Control Systems. Financial information related to these business segments is
included in Note H of Notes to Condensed Consolidated Financial Statements.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">On August&nbsp;7, 2006, we purchased certain assets related to the American National Standards Institute
(&#147;ANSI&#148;) medium voltage switchgear and circuit breaker business of General Electric Company&#146;s
(&#147;GE&#148;) Consumer &#038; Industrial unit located at its West Burlington, Iowa facility. We refer to the
acquired product line as &#147;Power/Vac&#174;.&#148; We are currently relocating the Power/Vac&#174; product line from
GE&#146;s facility in West Burlington, Iowa, to our facilities in Houston, Texas. The relocation of the
product line and related activities is expected to be completed in the first half of fiscal year
2008. GE will continue to manufacture products and supply them to Powell during the transition
period.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Overall, we continue to experience strong market demand for our products and services. Pricing in
our markets has improved in conjunction with the overall increase in business activity. We believe
this increase was a result of the petrochemical and utility markets entering into a new investment
cycle. Customer inquiries, or requests for proposals, steadily strengthened throughout fiscal year
2007. This increase in customer inquiries led to increased orders in fiscal year 2007 and,
accordingly, a very strong backlog of orders continuing into fiscal year 2008.
</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 $24.3&nbsp;million to $147.1&nbsp;million in the first quarter of fiscal 2008
compared to $122.8&nbsp;million in the first quarter of fiscal 2007. Revenues increased as the Company
has responded to strong market demand by increasing our capacity and through put. For the first
quarter of fiscal 2008, domestic revenues increased by 32.9% to $105.5&nbsp;million compared to the
first quarter of 2007. Total international revenues were $41.6&nbsp;million in the first quarter of 2008
compared to $43.4&nbsp;million in the first quarter of 2007. International revenues are primarily
related to energy related investments, principally oil and gas projects. Gross profit for the first
quarter of fiscal 2008 increased by approximately $6.6&nbsp;million to $26.7&nbsp;million as a result of
improved pricing and productivity. Gross profits as a percentage of revenues increased to 18.1% in
the first quarter of fiscal 2008, compared to 16.4% in the first quarter of fiscal 2007.
</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 business segment recorded revenues of $141.1&nbsp;million in the first
quarter of fiscal 2008, compared to $117.3&nbsp;million for the first quarter of fiscal 2007. In the
first quarter of 2008, revenues from public and private utilities
were approximately $43.7&nbsp;million,
compared to $38.3&nbsp;million in the first quarter of fiscal 2007. Revenues from commercial and
industrial customers totaled $86.2&nbsp;million in the first quarter
of 2008, an increase of $13.7
million compared to the first quarter of fiscal 2007. Municipal and transit projects generated
revenues of $11.2&nbsp;million in the first quarter of fiscal 2008 compared to $6.5&nbsp;million in the first
quarter of fiscal 2007.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Business segment gross profit, as a percentage of revenues, was 17.6% in the first quarter of
fiscal 2008, compared to 16.0% in the first quarter of fiscal 2007. Excluding the direct impact of
the Power/Vac&#174; product line, business segment gross profit would have been approximately 20.9% in
the first quarter of fiscal 2008.
</DIV>


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

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our Process Control Systems business segment recorded revenues of $6.0&nbsp;million in the first quarter
of fiscal 2008, an increase from $5.4&nbsp;million in the first quarter of fiscal 2007. Business segment
gross profit, as a percentage of revenues, increased to 30.7% in the first quarter of fiscal 2008
compared to 25.1% in the first quarter of fiscal 2007. This increase resulted from a favorable mix
of jobs with increased value-added services.

<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 increased to 13.7% of revenues in the
first quarter of fiscal 2008 compared to 13.3% of revenues in the first quarter of fiscal 2007.
Selling, general and administrative expenses were $20.1&nbsp;million for the first quarter of fiscal
2008 compared to $16.3&nbsp;million for the first quarter of fiscal 2007. Selling, general and
administrative expenses increased primarily due to increased costs related to the
integration of the Power/Vac&#174; product line and related operations and increased payroll costs,
which are consistent with the increase in volume.
</DIV>


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

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Interest expense was $0.9&nbsp;million in the first quarter of 2008, an increase of approximately $0.2
million compared to the first quarter of fiscal 2007. The increase in interest expense is primarily
due to interest expense related to increased borrowings necessary to support our increased volume
and the acquisition of the Power/Vac&#174; product line.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Interest income was $0.1&nbsp;million in the first quarter of fiscal 2008 compared to $0.2&nbsp;million in
the first quarter of fiscal 2007. This decrease resulted as cash was used to fund working capital
in the first quarter of fiscal 2008.
</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 for income taxes reflects an effective tax rate on earnings before income taxes of
36.5% in the first quarter of fiscal 2008 compared to 36.9% in the first quarter of fiscal 2007.
Our effective tax rate is impacted by 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">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: 12pt"><I>Net Income</I>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In the first quarter of fiscal 2008, we recorded net income of $3.6&nbsp;million, or $0.32 per diluted
share, compared to $2.0&nbsp;million, or $0.18 per diluted share, in the first quarter of fiscal 2007.
We had higher revenues and improved gross profits in all of our business segments, partially offset
by an increase in selling, general and administrative expenses associated with higher levels of
business activity and increased administrative costs related to the integration of the Power/Vac&#174;
product line.
</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 at December&nbsp;31, 2007, was $501.7&nbsp;million, compared to $464.5&nbsp;million at September
30, 2007 and $384.5&nbsp;million at the end of the first quarter of fiscal 2007. New orders placed
during the first quarter of fiscal 2008 totaled $185.1&nbsp;million compared to $147.5&nbsp;million in the
first quarter of fiscal 2007.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have maintained a positive liquidity position. Working capital was $124.4&nbsp;million at December
31, 2007, compared to $101.3&nbsp;million at September&nbsp;30, 2007. As of December&nbsp;31, 2007, current assets
exceeded current liabilities by 1.9 times and our debt to total capitalization ratio was 21.8%.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">At December&nbsp;31, 2007, we had cash, cash equivalents and marketable securities of $6.6&nbsp;million,
compared to $5.3&nbsp;million at September&nbsp;30, 2007. Long-term debt and capital lease obligations,
including current maturities, totaled $50.0&nbsp;million at December&nbsp;31, 2007, compared to $35.8&nbsp;million
at September&nbsp;30, 2007. We have a $58.5&nbsp;million revolving credit facility in the U.S. and an
additional &#163;4.0&nbsp;million (approximately $8.0&nbsp;million) revolving credit facility in the United
Kingdom, both of which expire in December&nbsp;2011. As of December&nbsp;31, 2007, there was approximately
$37.9&nbsp;million borrowed under these lines of credit, which is included in our long-term debt.
Amounts available under the U.S. revolving credit facility and the revolving credit facility in the
United Kingdom were approximately $25.2&nbsp;million and $3.4&nbsp;million, respectively, at December&nbsp;31,
2007. For further information regarding our debt, see Notes E and F of Notes to Condensed

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">During the first quarter of fiscal 2008 and 2007, cash used in operating activities was
approximately $14.6&nbsp;million and $5.6&nbsp;million, respectively. Cash flow from operations is primarily
influenced by demand for our products and services and is negatively impacted as our progress
payment terms with our customers extend beyond the payment terms with our suppliers. The payment
of annual incentive compensation in the first quarter of fiscal 2008, along with our recent
increase in volume and inventories needed for our existing backlog have resulted in negative cash
flow from operations in the first quarter of fiscal 2008. We anticipate that cash flow will be
generated from operations as our receivables are collected.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Investments in property, plant and equipment during the first quarter of fiscal 2008 totaled
approximately $0.7&nbsp;million compared to $5.4&nbsp;million during the first quarter of fiscal 2007. The
majority of our capital expenditures in the first quarter of fiscal 2007 were used to continue the
implementation of our new Enterprise Resource Planning System (&#147;ERP&#148;), and the expansion of two of
our operating facilities. These operating facility expansions were completed in fiscal 2007.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In December&nbsp;2007, the FASB issued SFAS No.&nbsp;141 (revised 2007), <I>Business Combinations </I>(&#147;SFAS No.
141R&#148;). SFAS No.&nbsp;141R establishes principles and requirements for how an acquirer recognizes and
measures in its financial statements the identifiable assets acquired, the liabilities assumed, any
noncontrolling interest in the acquiree and the goodwill acquired. SFAS No.&nbsp;141R also establishes
disclosure requirements to enable the evaluation of the nature and financial effects of the
business combination. SFAS No.&nbsp;141R is effective as of the beginning of an entity&#146;s fiscal year
that begins after December&nbsp;15, 2008, and will be adopted by us in the first quarter of fiscal 2010.
We are currently evaluating the potential impact, if any, of the adoption of SFAS No.&nbsp;141R on our

establishes accounting and reporting standards for ownership interests in subsidiaries held by
parties other than the parent, the amount of consolidated net income attributable to the parent and
to the noncontrolling interest, changes in a parent&#146;s ownership interest and the valuation of
retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS No.&nbsp;160 also

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The discussion and analysis of our financial condition and results of operations are based on our
consolidated financial statements, which have been prepared in accordance with accounting
principles generally accepted in the United States. The preparation of these consolidated
financial statements requires us to make estimates and assumptions that affect the reported amounts
of assets and liabilities, disclosures of contingent assets and liabilities known to exist at the
date of the consolidated financial statements and the reported amounts of revenues and expenses
during the reporting period. We evaluate our estimates on an ongoing basis, based on historical
experience and on various other assumptions that are believed to be reasonable under the
circumstances. There can be no assurance that actual results will not differ from those estimates.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">There have been no material changes to the Company&#146;s critical accounting policies as disclosed in
our Annual Report on Form 10-K for the year ended September&nbsp;30, 2007, except as follows:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Income Taxes &#151; </I>We account for uncertain tax positions in accordance with FASB Interpretation No.
48, <I>Accounting for Uncertainty in Income Taxes, an interpretation of SFAS No.&nbsp;109, Accounting for
Income Taxes</I>, (&#147;FIN 48&#148;). FIN 48 prescribes a comprehensive model for how companies should
recognize, measure, present and disclose in their financial statements uncertain tax positions
taken or to be taken on a tax return. The income tax laws and regulations are voluminous and are
often ambiguous. As such, we are required to make many subjective assumptions and judgments
regarding our tax positions that can materially affect amounts recognized in the consolidated
balance sheets and statements of operations.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Outlook for Fiscal 2008</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our backlog of orders is approximately $501.7&nbsp;million, the highest in the history of the Company.
Customer inquiries, or requests for proposals, have steadily strengthened over the past three
fiscal years. We anticipate that strong business activities in our principal markets will continue
throughout 2008.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Backlog growth has been driven by strong market demand in petrochemical, utility and transportation
markets. Additionally, our acquisitions in 2005 and 2006 have strengthened our strategic position
in the electrical power products market and expanded our product offering in the utility,
industrial and commercial markets. We enhanced our capabilities with the addition of medium and low
voltage IEC switchgear, intelligent motor control systems and power distribution solutions. The
Power/Vac&#174; switchgear product line acquired from GE has a large installed base and a broad customer
base across utility, industrial and commercial markets. These acquisitions provided us with a
significantly broader product portfolio and enhanced our capabilities to meet market demands around
the world. We also significantly enhanced our ability to reach a broader market and gain access to
new customers with a long-term commercial alliance with GE, which obligates GE to purchase from us
their requirements for ANSI medium voltage switchgear and circuit breakers and other related
equipment and components. The costs and effort to relocate the Power/Vac&#174; product line has
negatively impacted our earnings to date, and we expect this to continue through the first half of
2008 as we continue the integration efforts. We believe that our expanded product portfolio and new
channels to new markets have strengthened us in our Electrical Power Products business and
positioned us for continued growth.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We anticipate that we will continue to reinvest our cash generated from operations to support our
increased business activity and the acquired Power/Vac&#174; product line. Working capital needs are
anticipated to increase with growing levels of business activity. We believe that cash available
and borrowing capacity should be sufficient to finance anticipated operational activities, capital
improvements and debt repayments 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 floating rate
bank credit facility. At December&nbsp;31, 2007, $33.3&nbsp;million was outstanding, bearing interest at
approximately 6.5% per year. A hypothetical 100 basis point increase in variable interest rates
would result in a total annual increase in interest expense of approximately $333,000. 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 align="left" style="font-size: 10pt; margin-top: 6pt">We have significant operations that expose us to currency risk in the British Pound Sterling and to
a lesser extent the Euro. We believe the exposure to the effects that fluctuating foreign
currencies have on our consolidated results of operations is limited because the foreign operations
primarily invoice customers and collect obligations in their respective currencies or U.S. Dollars
and a portion of our credit facility is payable in British Pounds Sterling. Additionally, expenses
associated with these transactions are generally contracted and paid for in the same local
currencies. While we do not currently have any derivative contracts to hedge our exposure to
foreign currency exchange risk, we have in the past and may in the future enter into such
contracts.
</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 a negative effect on profit margin. While we may do so in the
future, we have not currently entered into any derivative contracts to hedge our exposure to
commodity risk. We continue to experience price increases with some of our key raw materials.
Competitive market pressures may limit our ability to pass these cost increases to our customers,
thus negatively impacting our earnings. Fluctuations in commodity prices may have a material impact
on our future earnings and cash flows.

</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have established and maintain a system of disclosure controls and procedures that are designed
to provide reasonable assurance that information required to be disclosed in our reports filed with
the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934 is recorded,
processed, summarized and reported within the time periods specified in the rules and forms of the
Commission and that such information is accumulated and communicated to our management, including
our Chief Executive Officer (&#147;CEO&#148;) and Chief Financial Officer (&#147;CFO&#148;), as appropriate, to allow
timely decisions regarding required disclosures.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Management, with the participation of our CEO and CFO, has evaluated the effectiveness of the
design and operation 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 December
31, 2007, our disclosure controls and procedures were effective to provide reasonable assurance
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

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">During the first quarter of fiscal 2008, management continued the domestic ERP implementation which
began in fiscal 2006. This conversion has 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 continuation of the domestic ERP
implementation.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Design and Operation of Control Systems</B>
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our management, including the CEO and CFO, does not expect that our disclosure controls and
procedures or our internal control over financial reporting will prevent or detect all errors and
all fraud. A control system, no matter how well designed and operated, can provide only
reasonable, not absolute, assurance that the control system&#146;s objectives will be met. The design
of a control system must reflect the fact that there are resource constraints, and the benefits of
controls must be considered relative to their costs. Further, because of the inherent limitations
in all control systems, no evaluation of controls can provide absolute assurance that misstatements
due to error or fraud will not occur or that all control issues and instances of fraud, if any,
within the Company have been detected. These inherent limitations include the realities that
judgments in decision-making can be faulty and breakdowns can occur because of simple error or
mistakes. Controls can be circumvented by the individual acts of some persons, by collusion of two
or more people, or by management override of the controls. The design of any system of controls is
based in part on certain assumptions about the likelihood of future events, and there can be no
assurance that any design will succeed in achieving its stated goals under all potential future
conditions. Over time, controls may become inadequate because of changes in conditions or
personnel, or deterioration in the degree of compliance with policies or procedures. Because of
the inherent limitations in a cost-effective control system, misstatements due to error or fraud
may occur and not be detected.

</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We 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">Despite attempts at mediation, the parties could not resolve their dispute, and a jury trial
commenced in December&nbsp;2006. On May&nbsp;1, 2007, the jury delivered its verdict in favor of the joint
venture, of which the Company is the managing partner, and determined that the Commission had
breached its contract with the joint venture. In accordance with court procedures, the court is currently reviewing other pending
motions, and the final judgment has not been entered. The jury&#146;s verdict is also subject to
appeal. However, based upon the jury&#146;s verdict and the court&#146;s opinion, we anticipate that we will
be able to recover the approximately $1.9&nbsp;million recorded in the condensed consolidated balance
sheet at December&nbsp;31, 2007.
