                                     PART I
 
ITEM 1. BUSINESS
 
     Powell Industries, Inc. ("Powell" or the "Company") was incorporated under
the laws of the State of Nevada in December 1968. The Company is the successor
to a corporation founded by William E. Powell in 1947, which merged into the
Company in 1977. During 1996 the Company completed the sale of its gas turbine
packaging business and its microprocessor based distributed control equipment
business. These businesses were operated by U. S. Turbine Corp. and
Powell-Process Systems Inc., wholly owned subsidiaries of the Company.
 
     The Company sells, designs, develops, manufactures, packages and services
systems and equipment for the distribution, control and management of electrical
energy and other dynamic processes. The Company's offices are located in
Houston, Texas with plants located in Houston, Greenville and Jacinto Port,
Texas; Elyria, Ohio; Franklin Park, Illinois; Fremont and Pleasanton,
California; and Norcross, Georgia. Most of the products manufactured by the
Company are made pursuant to specifications required for a particular order.
 
PRODUCTS AND SYSTEMS
 
     Powell designs, develops, manufactures, sells and services electrical power
distribution and control equipment and systems through its subsidiaries: Powell
Electrical Manufacturing Company; Powell-ESCO Company; Unibus, Inc.;
Delta-Unibus Corp. and Transdyn Controls, Inc. As applicable to the context,
"Company' is also sometimes used herein to refer to Powell and its subsidiaries.
 
     The principal products are switchgear and related equipment, bus duct and
process control systems. These products and systems are utilized primarily by
refineries, petrochemical plants, utilities, paper mills, offshore platforms,
commuter railways, vehicular transportation and numerous other industrial,
commercial and governmental facilities. A brief description of each of the major
products follows:
 
  Switchgear and other related Equipment:
 
     Free-standing metal enclosures containing a selection of electrical
components that protect, monitor and control the flow of electricity from its
source to motors, transformers and other electrically powered equipment. Major
electrical components include customized portable buildings (PCR(R)), circuit
breakers, protective relays, meters, control switches, fuses, motor control
centers and both current and potential transformers. During the fiscal years
ended October 31, 1996, 1995 and 1994, sales and service of switchgear and other
related equipment accounted for 76%, 73% and 71%, respectively, of consolidated
revenues of the Company.
 
  Bus Duct:
 
     Bus duct consists of insulated power conductors housed in a metal
enclosure. Individual pieces of bus duct are arranged in whatever physical
configuration may be required to distribute electrical power to or from a
generator, transformer, switching device or other electrical apparatus. Powell
can provide the nonsegregated phase, segregated phase and isolated phase styles
of bus duct with numerous amperage and voltage ratings. Sales of bus duct
accounted for 15%, 15% and 15% of consolidated revenues for fiscal years 1996,
1995 and 1994, respectively.
 
  Process Control Systems:
 
     The process control systems supplied by the Company consist principally of
instrumentation, computer control, communications, and data management systems.
Demand for process control systems has been for modernization and expansion
projects as well as new facilities that mainly serve the transportation,
environmental and utilities industries. During the fiscal years ended October
31, 1996, 1995 and 1994, sales of process control systems accounted for 9%, 12%
and 14%, respectively, of consolidated revenues of the Company.
 
                                        1
<PAGE>   3
 
SUPPLIERS
 
     All of the Company's products are manufactured using components and
materials that are readily available from numerous domestic suppliers. The
Company has three principal suppliers of components and anticipates no
difficulty in obtaining its components in sufficient quantities to support its
manufacturing and assembly operations.
 
METHODS OF DISTRIBUTION AND CUSTOMERS
 
     The Company's products are sold through manufacturers' representatives and
its internal sales force. The Company is not dependent on any single customer
for sales and the loss of any specific customer would not have a material
adverse effect upon the Company. No single customer or export country accounted
for more than 10% of consolidated revenues in the fiscal years ended 1996, 1995
or 1994. Export revenues were $63,884,000, $39,491,000 and $41,151,000 in fiscal
years 1996, 1995 and 1994, respectively. See Note H of the Notes to Consolidated
Financial Statements showing in what geographic area these revenues were
recorded.
 
COMPETITION
 
     The Company is engaged in a highly competitive business which is
characterized by a small number of much larger companies that dominate the bulk
of the market and a large number of smaller companies that compete for a limited
share of such market. In the opinion of management, the competitive position of
the Company is dependent on the ability of the Company to provide quality
products to a customer's specifications, on a timely basis, at a competitive
price, utilizing state-of-the-art materials, design and production methods. Some
of the Company's principal competitors are larger and have greater capital and
management resources.
 
EMPLOYEES
 
     At October 31, 1996, the Company employed 945 employees on a full-time
basis. Management considers its employee relations to be good.
 
BACKLOG
 
     The Company's backlog of orders was $106,457,000 and $103,315,000 at
October 31, 1996 and 1995, respectively, and the percentage of its 1996 year end
backlog that it does not expect to fill in fiscal year 1997 is 25%. Orders
included in the backlog are represented by purchase orders which the Company
believes to be firm. The terms on which the Company accepts orders include a
penalty for cancellation. Historically, no material amount of orders included in
backlog has been canceled. No material portion of the Company's business is
seasonal in nature.
 
RESEARCH AND DEVELOPMENT
 
     During the fiscal years ended October 31, 1996, 1995 and 1994, the Company
spent approximately $2,283,000, $1,843,000 and $1,670,000 respectively, on
research and development programs.

</TABLE>
 
ITEM 3. LEGAL PROCEEDINGS
 
     On August 5, 1993, the Company was served with a lawsuit by National
Westminster Bank plc ("NatWest") alleging the Company had defaulted on a
Construction Guaranty provided to NatWest in 1992 in connection with a project
at MacDill Air Force Base. NatWest is seeking damages in excess of $20,000,000.
The Company has denied the substantive allegations of the complaint and has
filed counterclaims for damages against NatWest alleging fraud, bad faith and
failure to preserve and protect its collateral and seeking a declaratory
judgement that the Company is not in default of the Construction Guaranty.
 
     The ultimate disposition of the NatWest litigation is not presently
determinable. Accordingly, although an unfavorable outcome to the NatWest
litigation could have a material effect on the Company's financial position and
results of operations, the Company believes it would be unreasonable to conclude
that an unfavorable outcome is probable.
 
     The Company is party to other disputes arising in the ordinary course of
business. Management does not believe the ultimate outcome of these disputes
will materially effect the financial position or results of operations of the
Company.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     There were no matters which were submitted to a vote of security holders
through proxies, or otherwise, during the fourth quarter of the fiscal year
ended October 31, 1996.

REVENUES
 
     The Company reported revenues of $170,123,000, $139,534,000 and
$119,453,000 in fiscal years 1996, 1995 and 1994 respectively. Revenues
increased 22% in fiscal year 1996 as compared to fiscal year 1995 due primarily
to the increased volume of shipments of electrical distribution equipment to
export customers. Revenues increased 17% in fiscal year 1995 as compared to
fiscal year 1994 due primarily to the improvement in revenues of electrical
distribution equipment to domestic transit customers.
 
     Export revenues continued to be an important component of the Company's
operations accounting for 38%, 28% and 34% of consolidated revenues in fiscal
years 1996, 1995 and 1994, respectively. A schedule is provided in Note H of the
Notes to Consolidated Financial Statements showing in which geographic area
these sales were made. Management anticipates that consolidated revenues will
increase in fiscal 1997 and that export revenues will continue to contribute
approximately 35% to 40% to consolidated revenues.
 
GROSS PROFIT
 
     Gross profit, as a percentage of revenues, was 25.3%, 22.2% and 22.3% in
fiscal years 1996, 1995 and 1994, respectively. Gross profit improved in fiscal
year 1996 from fiscal year 1995 due to improved prices, higher volumes and
higher margin contracts and services resulting primarily from a more favorable
economy in most of the markets in which the Company competes. Gross profit
varied only slightly from fiscal year 1995 to fiscal year 1994 due to changes in
product mix. The Company continues to focus on productivity improvements to
respond to the competitive market it serves.
 
SELLING, GENERAL AND ADMINISTRATIVE
 
     Selling, general and administrative expenses as a percentage of revenues
were 15.8%, 14.5% and 16.3% for fiscal years 1996, 1995 and 1994, respectively.
The increase in fiscal year 1996, as a percentage of revenues is due to higher
marketing, incentives and commissions expenses. The decrease in fiscal year 1995
as a percentage of revenues, is due to a higher revenue volume without a
corresponding increase in costs.
 
INTEREST, NET
 
     Interest expense (net of interest income) is lower in fiscal years 1996 and
1995 primarily due to a reduction in total debt.
 
INCOME TAX PROVISION
 
     The effective tax rate on earnings from continuing operations before income
taxes was 33%, 30% and 29% for fiscal years 1996, 1995 and 1994, respectively.
The effective tax rates are lower than the statutory rate due primarily to
foreign sales corporation credits.

EARNINGS FROM CONTINUING OPERATIONS
 
     Earnings from continuing operations recorded in fiscal year 1996 were
$10,758,000 or $1.00 per share. This represented a 52.0% percent increase in
earnings when compared to fiscal year 1995 earnings. The increase was primarily
due to the factors discussed above. Earnings from continuing operations recorded
in fiscal year 1995 were $7,080,000 or $.67 per share, an increase of 55.3%
compared to net earnings in fiscal year 1994.
 
DISCONTINUED OPERATIONS
 
     See Note L to Notes to Consolidated Financial Statements for discussion of
the operations that were discontinued in fiscal year 1996.
 
NET EARNINGS
 
     Net earnings were $4,760,000 or $.44 per share in fiscal year 1996 compared
to $5,698,000 or $.54 per share and $4,395,000 or $.42 per share in fiscal year
1995 and 1994, respectively. The losses from discontinued operations, explained
in the previous paragraph, resulted in lower net earnings in fiscal year 1996 as
compared to fiscal year 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In October 1995, the Company entered into a $15,000,000 revolving line of
credit agreement with a major domestic bank. As of October 31, 1996, the Company
did not have borrowings outstanding under this revolving line of credit. The
Company's ability to satisfy its cash requirements is evaluated by analyzing key
measures of liquidity applicable to the Company. The following table is a
summary of the measures which are significant to management.

Working capital.............................  $46,505,000    $32,642,000    $30,351,000
Current ratio...............................    2.42 to 1      2.30 to 1      2.39 to 1
Debt to total capitalization................      .1 to 1        .1 to 1        .2 to 1
</TABLE>
 
     Management believes that the Company continues to maintain a strong
liquidity position. The increase in working capital at October 31, 1996, as
compared to October 31, 1995, is due mainly to increases in accounts receivable
and costs and estimated earnings in excess of billings, partially offset by
increases in accrued liabilities.
 
     Capital expenditures totaled $3,349,000 during fiscal year 1996 compared to
$3,378,000 during fiscal year 1995. During fiscal year 1996 the Company approved
major capital expenditures for future plant expansions at three operating
facilities totalling approximately $12,000,000. Management expects the Company's
capital expenditures to increase substantially in fiscal year 1997 due to these
plant expansions.
 
     The Company's fiscal year 1997 asset management program will continue to
focus on the collection of receivables and reduction in inventories. Management
believes that the cash and cash equivalents of $8,935,000 at October 31, 1996,
along with funds generated from operating activities and funds available through
borrowings from the credit line will be sufficient to meet the capital
requirements and operating needs of the Company.
 
EFFECTS OF INFLATION AND RECESSION
 
     During the last three years, the Company has not experienced any
significant effects of inflation on its operations. Management continues to
evaluate the potential impact inflation could have on future growth and minimize
the impact by including escalation clauses in long-term contracts. Recent
marketing and financial reports indicate that the current economic conditions
should improve slightly in 1997 and the Company does not anticipate significant
increases in inflation in the immediate future.

NEW ACCOUNTING STANDARDS
 
     The Company is required to adopt SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of" and
SFAS No. 123, "Accounting for Stock Based Compensation" during its fiscal year
ending October 31, 1997. Adoption of SFAS No. 121 will not have significant
effect on the Company's consolidated financial statements. The Company expects
to disclose the fair value of options granted in a footnote to its October 31,
1997 consolidated financial statements, as required by SFAS No. 123.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To The Board of Directors and Stockholders of Powell Industries, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Powell
Industries, Inc. (a Nevada Corporation) and subsidiaries as of October 31, 1996
and 1995, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended October
31, 1996. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Powell
Industries, Inc. and subsidiaries as of October 31, 1996 and 1995, and the
results of their operations and their cash flows for each of the three years in
the period ended October 31, 1996, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
A. BUSINESS AND ORGANIZATION
 
     Powell Industries, Inc. ("Powell" or the "Company") was incorporated under
the laws of the State of Nevada in December 1968. The Company is the successor
to a corporation founded by William E. Powell in 1947, which merged into the
Company in 1977.
 
     Powell designs, develops, manufactures, sells and services electrical power
distribution and control equipment and systems through its subsidiaries: Powell
Electrical Manufacturing Company; Powell-ESCO Company; Unibus, Inc.;
Delta-Unibus Corp. and Transdyn Controls, Inc. As applicable to the context,
"Company" is also sometimes used herein to refer to Powell and its subsidiaries.
 
B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
Powell Industries, Inc. and its wholly-owned subsidiaries (the Company). All
material intercompany accounts and transactions have been eliminated.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of less than three months to be cash equivalents.
 
  Accounts Receivable
 
     The Company's receivables are generally not collateralized. Management
performs ongoing credit analyses of the accounts of its customers and provides
allowances as deemed necessary. Accounts receivable at October 31, 1996 and 1995
include $3,603,000 and $2,835,000, respectively due from customers in accordance
with applicable retainage provisions of engineering and construction contracts,
which will become billable upon completion of such contracts. Approximately
$706,000 of the retained amount at October 31, 1996 is expected to be billed
subsequent to 1997.
 
  Inventories
 
     Inventories are stated at the lower of cost (primarily first-in, first-out
method) or market and include material, labor and manufacturing overhead.
 
  Property, Plant and Equipment
 
     Property, plant and equipment is stated at cost and is depreciated using
the straight-line method over the estimated useful lives of the assets.
Expenditures for repairs and maintenance are charged to expense when incurred.
Expenditures for major renewals and betterments, which extend the useful lives
of existing equipment, are capitalized and depreciated. Upon retirement or
disposition of property and equipment, the cost and related accumulated
depreciation are removed from the accounts and any resulting gain or loss is
recognized in the statements of operations.
 
  Amortization of Intangibles
 
     Included in other assets are net intangible assets totalling $2,172,000 and
$2,461,000 at October 31, 1996 and 1995, respectively. Intangible assets
primarily include goodwill and patents which are amortized using the
straight-line method over periods ranging from five to twenty years. The
accumulated amortization of intangible accounts totalled $1,873,000 and
$1,540,000 at October 31, 1996 and 1995, respectively. Management continually
evaluates whether events or circumstances have occurred that indicate the
remaining

                    POWELL INDUSTRIES, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
estimated useful life of intangible assets may warrant revision or that
remaining balances may not be recoverable.
 
  Revenue Recognition
 
     Revenues from product sales are recognized at the time of shipment.
Revenues related to multiple unit orders and their associated costs are recorded
as identifiable units are delivered. Contract revenues are recognized on a
percentage-of-completion basis primarily using labor dollars incurred to date in
relation to estimated total labor dollars of the contracts to measure the stage
of completion. Contract costs include all direct material and labor costs and
those indirect costs related to contract performance, such as indirect labor,
supplies and depreciation costs. Provisions for total estimated losses on
uncompleted contracts are recorded in the period in which they become evident.
 
  Warranties
 
     The Company provides for estimated warranty costs at the time of sale based
upon historical rates applicable to individual product lines. In addition,
specific provisions are made when the costs of such warranties are expected to
exceed accruals.
 
  Research and Development Expense
 
     Research and development costs are charged to expense as incurred. Such
amounts were $2,283,000, $1,843,000 and $1,670,000 in fiscal years 1996, 1995
and 1994, respectively.
 
  Earnings per Common and Common Equivalent Share
 
     Per share data has been computed based on the weighted average number of
common and common equivalent shares outstanding of 10,764,656, 10,611,331 and
10,509,371 in fiscal years 1996, 1995 and 1994, respectively.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Reclassification
 
     Certain reclassifications of prior year amounts have been made in order to
conform with the classifications used in the current year presentation.
 
  Income Taxes
 
     The Company accounts for income taxes using Statement of Financial
Accounting Standards (SFAS) No. 109 "Accounting for Income Taxes". Under SFAS
No. 109, deferred tax assets and liabilities are computed based on the
difference between the financial statements and income tax bases of assets and
liabilities using enacted tax rates. Under this standard, the effect on deferred
taxes of a change in tax rates is recognized in income in the period that the
tax rate changes.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  New Accounting Standards
 
     The Company is required to adopt SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of" and
SFAS No. 123, "Accounting for Stock Based Compensation" during its fiscal year
ending October 31, 1997. Adoption of SFAS No. 121 will not have significant
effect on the Company's consolidated financial statements. The Company expects
to disclose the fair value of options granted in a footnote to its October 31,
1997 consolidated financial statements, as required by SFAS No. 123.

E. EMPLOYEE BENEFIT PLANS
 
     The Company has a defined contribution plan (4.01k) for substantially all
of its employees. The Company matches 50% of employee contributions up to six
percent of their salary. The Company recognized expense of $736,000, $658,000
and $607,000 in fiscal years 1996, 1995 and 1994, respectively, under this plan.
 
     Three long service employees are participants in a deferred compensation
plan providing payments in accordance with a predetermined plan upon retirement
or death. The Company recognizes the cost of this plan over the projected years
of service of the participant. The Company has insured the lives of these key
employees to assist in the funding of the deferred compensation liability.
 
     In 1992, the Company formed a new subsidiary and entered into a stock
participation agreement with two key employees of the subsidiary providing for
them to purchase stock in the subsidiary for a nominal amount. The agreement
allows the two employees to sell their stock back to the Company after October
1997 for $1,000,000. The Company has established a deferred compensation
liability and prepaid compensation expense included in other assets, based on
the net present value of the amount. The charge to fiscal years 1996, 1995 and
1994 for compensation expense and interest was $206,000, $156,000 and $197,000
respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     During January 1992, the Company established an employee stock ownership
plan (ESOP) for the benefit of substantially all full-time employees other than
employees covered by a collective bargaining agreement to which the ESOP has not
been extended by agreement or by action of the Company. The ESOP purchased
793,525 shares of the Company's common stock from a major stockholder. The
funding for this plan was provided through a loan from the Company of
$4,500,000. This loan will be repaid over a twenty-year period with equal
payments of $424,000 per year including interest at 7%. The Company recorded
deferred compensation as a contra-equity account for the amount loaned to the
ESOP in the accompanying consolidated balance sheet. The Company is required to
make annual contributions to the ESOP to enable it to repay its loan to the
Company. The deferred compensation account is amortized as compensation expense
over twenty years as employees earn their shares for services rendered. The loan
agreement also provides for prepayment of the loan if the Company elects to make
any additional contributions. During fiscal year 1994 the Company made an
additional contribution of $331,000 to provide ESOP benefits to the increased
number of eligible employees. The compensation expense for fiscal years 1996,
1995 and 1994 was $268,000, $147,000 and $452,000, respectively.
 
     In November 1992, the Company established a plan to extend to retirees
health benefits which are available to active employees under the Company's
existing health plans. Participants become eligible for retiree health care
benefits when they retire from active service at age 55 with ten years of
service. Generally, the health plans pay a stated percentage of medical and
dental expenses reduced for any deductible and co-payment. These plans are
unfunded. Medical coverage may be continued by the retired employee up to age 65
at the average cost to the Company of active employees. At the age of 65, when
the employee becomes eligible for Medicare, the benefits provided by the Company
are reduced by the amount provided by Medicare and the cost to the retired
employee is reduced to 50 percent of the average cost to the Company of active
employees.
 
     In January 1994, the Company modified its postretirement benefits to
provide retiree healthcare benefits to only current retirees and active
employees who will be eligible to retire by December 31, 1999. Participants
eligible for such benefits will be required to pay between 20 percent and 100
percent of the Company's average cost of benefits based on years of service. In
addition, benefits will end upon the employee's attainment of age 65. The effect
of these modifications significantly reduced the Company's postretirement
benefits cost and accumulated benefits obligation.

     The assumed health care cost trend rate in measuring the accumulated
postretirement benefits obligation was ten percent in fiscal year 1996
decreasing to six percent by fiscal year 2000. If the health care trend rate
assumptions were increased by one percent, the accumulated postretirement
benefits obligation, as of October 31, 1996, would be increased by 8.8 percent.
The effect of this change on the net postretirement benefit cost for 1996 would
be an increase of 8.7 percent. The weighted average discount rate used in
determining the accumulated postretirement benefits obligation was 7.0 and 6.5
percent for fiscal years 1996 and 1995, respectively.
 
F. DEBT
 
     In June 1990, the Company concluded a private placement of $15,000,000 in
term notes due through June 1997. The notes, with interest at a fixed rate of
10.4 percent, are unsecured. The loan agreements require, among other things,
maintenance of minimum levels of working capital and tangible net worth and
places various restrictions on the payment of dividends and investments, as
defined. The amounts of funds available for payment of dividends and
investments, as defined, at October 31, 1996 and 1995 were $16,784,000 and
$15,630,000, respectively.
 
     In October 1995, the Company entered into an agreement for a $15,000,000
revolving line of credit with a major U.S. bank that replaced an existing line
of credit. The agreement provides for interest at the bank's prime rate on
amounts borrowed and a fee of .25 percent on the unused balance. The agreement
contains customary affirmative and negative covenants and requirements to
maintain a minimum level of working capital and tangible net worth and places
restrictions on the payment of dividends and investments, as defined. The
agreement matures on August 15, 1998. As of October 31, 1996, the Company did
not have any balance outstanding under this line of credit.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Letters of Credit
 
     The Company is contingently liable for secured and unsecured letters of
credit totaling approximately $2,514,000 that were outstanding at October 31,
1996.
 
  Litigation
 
     On August 5, 1993, the Company was served with a lawsuit by National
Westminster Bank plc ("NatWest") alleging the Company had defaulted on a
Construction Guaranty provided to NatWest in 1992 in connection with a project
at MacDill Air Force Base. NatWest is seeking damages in excess of $20,000,000.
The Company has denied the substantive allegations of the complaint and has
filed counterclaims for damages against NatWest alleging fraud, bad faith and
failure to preserve and protect its collateral and seeking a declaratory
judgement that the Company is not in default of the Construction Guaranty.
 
     The ultimate disposition of the NatWest litigation is not presently
determinable. Accordingly, although an unfavorable outcome to the NatWest
litigation could have a material effect on the Company's financial position and
results of operations, the Company believes it would be unreasonable to conclude
that an unfavorable outcome is probable.
 
     The Company is party to other disputes arising in the ordinary course of
business. Management does not believe the ultimate outcome of these disputes
will materially effect the financial position or results of operations of the
Company.
 
J. STOCK OPTION PLAN
 
     In March 1992, the stockholders approved an amendment to a plan that was
adopted in March 1989, in which 750,000 shares of common stock would be made
available through an incentive program for certain employees of the Company. The
awards under this plan are subject to certain conditions and restrictions as
determined by the Compensation Committee of the Board of Directors. The fair
market value of the shares awarded is deferred and amortized to compensation
expense on a straight-line basis over the vesting period. The vesting period for
shares awarded vary from the date of the grant up to five years. In March 1996,
the stockholders approved an amendment to increase the maximum shares available
under the Plan from 750,000 shares to 1,500,000 shares of common stock. The
Company recognized compensation expense related to stock grants pursuant to this
plan of $487,000, $156,000 and $178,000 in fiscal years 1996, 1995 and 1994,
respectively.
 
     There were 820,083 shares available under the plan to be granted as of
October 31, 1996. Stock option plan activity (number of shares) for the Company
during fiscal years 1996, 1995 and 1994 was as follows:

                            POWELL INDUSTRIES, INC.
                      INCENTIVE COMPENSATION PLAN FOR 1996

                                 DECEMBER 1995



1.       PLAN PURPOSE

         The purpose of the plan is to recognize and reward key corporate and
         subsidiary employees for their contributions to the growth and
         profitability of Powell Industries, Inc. and its operating
         subsidiaries through the opportunity to earn incentive compensation,
         in addition to their base salaries, based on the performance of the
         Company or subsidiary.

2.       GENERAL DESCRIPTION

         Key corporate and subsidiary executives and managers will be selected
         for participation on an annual basis.  For each participant, a maximum
         incentive compensation opportunity will be established, and expressed
         as a percentage of the individual's base salary at the beginning of
         the plan year.  The actual amount of incentive compensation earned by
         each participant will be based on the performance of the Company or
         subsidiary against pre-established performance measures.  The
         performance measures for the subsidiary participants will include
         "return on revenues" and "revenue growth".  For corporate
         participants, the performance measures will include "Powell
         Industries, Inc. earnings per share", and "revenue growth".  Specific
         performance levels will be established each year based on an
         assessment of historical results, the budgeted performance for the
         plan year, and general business conditions.

         The plan will be administered by the Compensation Committee of the
         Board of Directors, in conjunction with the Chief Executive Officer.

3.       ELIGIBILITY AND INCENTIVE COMPENSATION OPPORTUNITY

         On an annual basis key corporate and subsidiary participants will be
         identified for participation.  Participation in one year does not
         guarantee participation in the following year.

         Subsidiary presidents will submit their recommended participants to
         the CEO for approval.  In addition, each subsidiary president may
         identify a general incentive "pool", which may be used to recognize
         the contributions of individuals within the subsidiary who are not
         named participants.





                                     Page 1
<PAGE>   2
         The CEO will recommend corporate participants for approval by the
         Compensation Committee.  The CEO may identify a general incentive
         "pool" which may be used to recognize the contributions of individuals
         who are not named participants.

         For each named participant, their "maximum incentive opportunity" will
         be identified, which is expressed as a percentage of base salary at
         the beginning of the plan year.

4.       PERFORMANCE MEASURES AND WEIGHTS

         The following performance measures will be used to measure the
         performance of the Company and determine the incentive award earned by
         each participant.  The weighting percentage reflects the relative
         weight given to each performance measure.

         SUBSIDIARY PARTICIPANTS

         o       70% Return on Revenues - Net profits before taxes divided by
                 total revenues

         o       30% Percent Growth of Total Revenues

         CORPORATE PARTICIPANTS

         o       70% Powell Industries, Inc. Earnings Per Share

         o       30% Percent Growth of Total Revenues Over Prior Year

         Prior to the beginning of the plan year, the performance standards for
         each subsidiary and Powell Industries, Inc. will be finalized,
         approved by the Compensation Committee, and communicated to
         participants.  The performance standards will be based on historical
         results, management's expectations for the coming year, and the
         general business environment.  The CEO will approve subsidiary
         performance standards, and the Compensation Committee will approve the
         company-wide performance standards.

         For 1995, the revenue growth standard for the corporation and
         subsidiaries will be 10%.  Beginning in 1996, the standard will be
         increased to 15%.

5.       COMPUTATION OF AWARDS

         For each subsidiary and Powell Industries, Inc., an Incentive
         Compensation Calculation Form will be prepared at the beginning of the
         plan year, which will include a listing of the participants, their
         base salary, and maximum incentive opportunity.  For each performance
         measure, a funding table will be attached which establishes the amount
         of incentive compensation earned at various performance levels.  The
         Incentive Compensation Calculation Form is attached.





                                     Page 2
<PAGE>   3
         In order to activate the plan for each subsidiary, the threshold
         Return on Revenue  (ROR) must be achieved.  If the ROR threshold is
         not achieved, no incentive awards will be paid, regardless of the
         revenue growth percentage.

         In order to activate the plan for corporate participants, the
         threshold Earnings Per Share (EPS) must be achieved.  If the EPS
         threshold is not achieved, no incentive awards will be paid,
         regardless of the revenue growth percentage.

         In computing performance results, ROR and EPS will be net of the
         accrued incentive compensation payments.

         In addition to the incentive award computed under this plan, the
         Compensation Committee may in its sole discretion, make additional
         discretionary awards to recognize significant individual
         contributions.  This discretionary award is limited to no more than
         30% of the individual's maximum incentive opportunity.

         The Compensation Committee, in conjunction with the CEO, may make
         adjustments to the subsidiary or Company performance results to
         eliminate the impact of extraordinary charges to earnings, both
         positive and negative.  The purpose of any such adjustment is to
         better reflect the performance of the subsidiary or Company. Each
         August, the Committee will meet to review the interim performance
         results of the Company and determine if extraordinary charges have
         occurred or are likely to occur that should be eliminated.

6.       PAYMENT OF AWARDS

         The annual incentive awards will be determined after the end of the
         plan year and paid as soon as practical.  Prior to payment of awards,
         the Compensation Committee will review and certify the incentive
         awards for all participants.

         Incentive awards will be computed based on the participant's base
         salary at the beginning of the plan year.

         A participant must be an active employee on the last day of the plan
         year in order to receive an incentive award.

         Participants added to the plan after the beginning of the plan year,
         will be eligible to receive a prorated award based on their salary
         when they became eligible.

         Participants who die, retire, or become disabled during the plan year
         will be eligible for a prorated award based on the number of months of
         active participation during the plan year.

7.       ADMINISTRATION OF PLAN

         The plan will be administered by the Compensation Committee, in
         conjunction with the CEO.  The Committee reserves the right to amend
         or terminate the plan at any





                                     Page 3
<PAGE>   4
         time, except that such amendment or termination will not affect any
         awards that have been earned but not paid.

             FIRST AMENDED AND RESTATED REVOLVING  PROMISSORY  NOTE


$15,000,000.00                                                  AUGUST  15, 1996


FOR VALUE RECEIVED, after date, without grace, in the manner, on the dates and
in the amounts so herein stipulated, the undersigned, POWELL INDUSTRIES, INC.,
a Nevada corporation, acting by and through its duly authorized officer,
("Borrower") , PROMISES TO PAY TO THE ORDER OF WELLS FARGO BANK (TEXAS),
NATIONAL ASSOCIATION, FORMERLY FIRST INTERSTATE BANK OF TEXAS, N.A. ("Lender"),
in Houston, Harris County, Texas, the sum of FIFTEEN MILLION AND N0/100 DOLLARS
($15,000,000.00) or, if less, the aggregate unpaid principal amount of advances
made by Lender to Borrower pursuant to this Note, in lawful money of the United
States of America, which shall be legal tender in payment of all debts and
dues, public and private, at the time of payment, and to pay interest on the
unpaid principal amount from date until maturity at a rate equal to the Stated
Rate (as hereinafter defined), not to exceed the maximum non-usurious interest
rate permitted by applicable law from time to time in effect as such law may be
interpreted, amended, revised, supplemented or enacted ("Maximum Rate"),
provided that if at any time the Stated Rate exceeds the Maximum Rate then
interest hereon shall accrue at the Maximum Rate.  In the event the Stated Rate
subsequently decreases to a level which would be less than the Maximum Rate or
if the Maximum Rate applicable to this Note should subsequently be changed,
then interest hereon shall accrue at a rate equal to the applicable Maximum
Rate until the aggregate amount of interest so accrued equals the aggregate
amount of interest which would have accrued at the Stated Rate without regard
to any usury limit, at which time interest hereon shall again accrue at the
Stated Rate.  As used herein, the Stated Rate shall mean, in the absence of
Borrower's exercise of a Eurodollar Rate Election (as defined in the Credit
Agreement) , the Prime Rate plus the applicable Base Rate Margin as set forth
below:


         RATIO OF-FUNDED INDEBTEDNESS TO          BASE RATE MARGIN
         EBITDA FOR THE PRECEDING FOUR (4)

In the event the Borrower exercises its right to select the Eurodollar Rate (as
defined in the Credit Agreement) , (i) such selection shall be in accordance
with the provisions of the Credit Agreement and (ii) the Stated Rate as to the
Eurodollar Rate Advance (as defined in the Credit Agreement) shall be the
Eurodollar Rate plus the applicable Libor Margin as set forth below:

The adjustment in the applicable Base Rate Margin and/or Libor Margin of this
Note shall be effective on the first of the month following receipt of
quarterly financial statements pursuant to Section 3.1 and Compliance
Certificate pursuant to Section 5.10 of the Credit Agreement indicating the
Ratio of Funded Indebtedness to EBITDA for the preceding four (4) fiscal
quarters (as such terms are defined in the Credit Agreement), provided that if,
for any reason, the applicable financial statements are delivered after the 1st
of the month approximately sixty (60) days following the end of the fiscal
quarter, the adjustment in Base Rate Margin or Libor Margin shall be
retroactive to the 1st of such month based upon the financial statements when
delivered.

Interest shall be due and payable monthly as it accrues on the first day of
each and every month, beginning November 1, 1995, and continuing regularly
thereafter until August 15, 1998, when the entire balance of principal and
accrued interest shall be due and payable.

This Note is the Revolving Note referred to in, is subject to, and is entitled
to the benefits of, the Credit Agreement dated as of October 20, 1995, as
amended by a First Amendment to Credit Agreement, dated of even date herewith,
between Borrower and Lender, as that Credit Agreement, as amended, may be
further amended, modified or supplemented from time to time (the "Credit
Agreement").  The Credit Agreement contains, among other things, provisions for
the acceleration of the maturity hereof upon the occurrence of certain stated
events.  All capitalized terms used herein which are defined in the Credit
Agreement shall have the same meaning as in the Credit Agreement.

It is agreed that time is of the essence of this agreement.  Upon the
occurrence of an Event of Default, Lender may accelerate and declare this Note
immediately due and payable as provided in the Credit Agreement.  Any failure
to exercise this option shall not constitute a waiver by Lender of the right to
exercise the same at any other time.

Upon the occurrence of an Event of Default under Section 6.1 of the Credit
Agreement or in the event this Note is declared due interest shall accrue in
accordance with the provisions of Section 1.9 of the Credit Agreement, but in
no event to exceed the Maximum Rate.

Borrower hereby agrees to pay all expenses incurred, including reasonable
attorneys' fees, all of which shall become a part of the principal hereof, if
this Note is placed in the hands of an attorney for collection or if collected
by suit or through any probate, bankruptcy or any other legal proceedings.

Interest charges will be calculated on amounts advanced hereunder on the actual
number of days these amounts are outstanding in accordance with the Credit
Agreement.  It is the intention of the parties hereto to comply with all
applicable usury laws; accordingly, it is agreed that notwithstanding any
provision to the contrary in this Note, or in any of the documents securing
payment hereof or otherwise relating hereto, no such provision shall require
the payment or permit the collection of interest in excess of the Maximum Rate.
If any excess of interest in such respect is provided for, or shall be
adjudicated to be so provided for, in this Note or in any of the documents
securing payment hereof or otherwise relating hereto, then in such event (1)
the provisions of this paragraph shall govern and control, (2) neither
Borrower, endorsers or guarantors, nor their heirs, legal representatives,
successors or assigns nor any other party liable for the payment hereof, shall
be obligated to pay the amount of such interest to the extent that it is in
excess of the Maximum Rate, (3) any such excess which may have been collected
shall be either applied as a credit against the then unpaid principal amount
hereof or refunded to Borrower, and (4) the provisions of this Note and any
documents securing payment of this Note shall be automatically reformed so that
the effective rate of interest shall be reduced to the Maximum Rate.  For the
purpose of determining the Maximum Rate, all interest payments with respect to
this Note shall be amortized, prorated and spread throughout the full term of
the Note so that the effective rate of interest on account of this Note is
uniform throughout the term hereof.

Borrower agrees that the Maximum Rate to be charged or collected pursuant to
this Note shall be the applicable indicated rate ceiling as defined in TEX.
REV.  CIV.  STAT.  ANN.  Art. 5069-1.04, provided that Lender may rely on other
applicable laws,  including without limitation laws of the United States, for
calculation of the Maximum Rate if the application thereof results in a greater
Maximum Rate.  Except as provided above, the provisions of this Note shall be
governed by the laws of the State of Texas.

Each maker, surety, guarantor and endorser (i) waives demand, grace, notice,
presentment for payment, notice of intention to accelerate the maturity hereof,
notice of acceleration of the maturity hereof and protest, (ii) agrees that
this Note and the liens securing its payment may be renewed, and the time of
payment extended from time to time, without notice and without releasing any of
the foregoing, and (iii) agrees that without notice or consent from any maker,
surety, guarantor, or endorser, Lender may release any collateral which may
from time to time be pledged to secure repayment of this Note, or may release
any party who might be liable for this Note.

Subject to the provisions of the Credit Agreement, Borrower may prepay this
Note, in whole or in part, at any time prior to maturity without penalty, and
interest shall cease on any amount prepaid.

As used in this Note, the term "Prime Rate" shall mean the variable rate of
interest announced by Lender from time to time as its prime rate of interest
and, without notice to the maker of this Note or any other person, such rate of
interest shall change as and when changes in that prime rate of interest are
announced.  The Prime Rate is set by Lender as a general reference rate of
interest, taking into account such factors as Lender may deem appropriate, it
being understood that many of Lender's commercial or other loans are priced in
relation to such rate, that it is not necessarily the lowest or best rate of
interest actually charged on any loan, and that Lender may make various
commercial or other loans at rates of interest having no relationship to the
Prime Rate.  If at any time the "Prime Rate" of Wells Fargo Bank (Texas),
National Association, formerly First Interstate Bank of Texas, N.A. is no
longer available, then the owner of this Note ("Owner") will designate a
different "Prime Rate" as announced by a national banking association of
owner's choice.

The principal of this Note represents funds which Lender will advance to
Borrower from time to time upon request of Borrower.  Any part of the principal
may be repaid by Borrower and thereafter reborrowed, provided the outstanding
principal amount of this Note shall never exceed the face amount of this Note.
Each advance shall constitute a part of the principal hereof and shall bear
interest from the date of the advance.  The provisions of TEX.  REV.  CIV.
STAT.  ANN.  Art. 5069-15.01, et seq, as may be amended, shall not apply to
this Note or to any of the security documents executed in connection with this
Note.
