Prospectus in its entirety.
 
                                  THE COMPANY
 
     Schuff Steel Company is a rapidly growing steel fabrication and erection
firm that provides a fully integrated range of steel construction services.
Schuff operates primarily in the southwestern United States with a concentration
in Arizona, Nevada and southern California, and has recently expanded its
operations into South America and Mexico. The Company is the largest steel
fabrication and erection firm serving the Arizona industrial and commercial
markets, a position it recently enhanced with the 1997 acquisition of B&K Steel
Fabrications, Inc. ("B&K Steel"). The Company also believes that it is the
leading steel fabricator and erector for the hotel and casino industry in
Nevada. Engineering News Record ranked the Company as the second largest steel
erection subcontractor in the United States based upon 1995 revenues and as the
largest steel erection subcontractor in the United States based upon 1994
revenues.
 
     Schuff has achieved significant growth in revenues and pre-tax income over
the past five years. Revenues have more than doubled from $47.0 million in 1992
to $103.9 million ($113.3 million giving pro forma effect to the 1997 B&K Steel
acquisition) in 1996. During that same period, pre-tax income have grown at a
compound annual growth rate of 101.5%, from $610,000 in 1992 to $10.1 million in
1996.
 
     The Company seeks to differentiate itself from its competitors by providing
a fully integrated range of steel construction services, including engineering,
detailing, fabrication and erection, and by providing a level of service and
expertise necessary to accommodate large, fast track projects. The Company
believes that there is an increasing trend in the industry to design and build
projects according to accelerated time schedules. The fast track,
"design-as-you-go" nature of these projects creates a demand for integrated
contractors that can (i) reduce the logistical and coordination problems
inherent in using multiple subcontractors and (ii) more efficiently respond to
rapid and multiple design changes while minimizing the project delays and cost
overruns commonly associated with such changes. The complexity and size of these
projects is particularly suited to contractors with extended financial and
operational capabilities. The Company believes that it has gained a reputation
in the industry as a reliable, fully integrated provider of engineering,
detailing, fabrication and erection services with the ability to complete large,
complex projects on a timely, cost efficient basis.
 
     The Company has provided its integrated fabrication and erection services
to a wide variety of projects, including hotels and casinos, office complexes,
hospitals, mining facilities, manufacturing plants, shopping malls, sports
stadiums, large diameter water pipes, and other public works projects. Examples
of major projects include: Bank One Ballpark, a baseball stadium featuring a
fully retractable steel roof being constructed for Major League Baseball's
Arizona Diamondbacks franchise; Agua Fria Siphon Project, an aqueduct system
with over two miles of specially fabricated 21 foot diameter pipe; MGM Grand
Hotel & Casino in Las Vegas, the world's largest hotel and casino; Intel Corp.'s
Fab 12 Plant, one of the largest semiconductor manufacturing plants in the
United States; and Bajo de la Alumbrera in Argentina, one of the largest copper
mines in the world.
 
                                        3
<PAGE>   5
 
     The Company believes that the steel fabrication and erection industry is
highly fragmented and that many of its competitors are small businesses that
offer limited services or confine operations to local or regional markets. Given
the trend toward the use of fully integrated contractors, the Company believes
the industry may experience consolidation and that it is well positioned to take
advantage of potential acquisition opportunities.
 
BUSINESS STRATEGY
 
     The Company's objective is to achieve and maintain a leading market
position in each of its geographic and specific product markets. The Company
seeks to achieve this objective by pursuing the following business strategies:
(i) promoting its ability to provide a fully integrated range of engineering,
detailing, fabrication and erection services, which enables the Company to
compete more effectively on large, complex, fast track, "design-as-you-go"
projects; (ii) focusing its engineering, detailing, fabrication and erection
expertise on distinct product segments requiring unique or innovative
techniques, where the Company typically experiences less competition; (iii)
diversifying its construction projects across a wide range of commercial,
industrial and specialty projects; and (iv) offering in-house project management
and engineering expertise not typically provided by steel fabricators or
erectors, which facilitates the Company's ability to procure contracts for
large, more complicated projects.
 
GROWTH STRATEGY
 
     The Company seeks to achieve continued growth and diminish the impact of
business and economic cycles by pursuing the following strategies: (i) promoting
growth internally by adding sales and marketing personnel dedicated to fast
growing markets, further developing its engineering and design capabilities and
fabrication capacity, and continually updating its fabrication and detailing
equipment and technologies; (ii) capitalizing on the highly fragmented nature of
the steel fabrication and erection industry by pursuing selective acquisitions
of companies that offer the Company increased plant facilities, opportunities to
increase market share in selected geographic markets, penetration of new product
market segments and access to domestic and international markets targeted by the
Company for geographic expansion; (iii) pursuing additional project
opportunities by continuing to diversify into new geographic and product
markets, leveraging its existing relationships with key national and
multi-national general contractors and other customers, and establishing new
strategic alliances; and (iv) expanding its international operations by pursuing
opportunities in South America, Mexico and Southeast Asia.
 
     The Company was incorporated in Arizona in 1976 and reincorporated under
the laws of Delaware in 1997. The Company's principal executive offices are
located at 420 South 19th Avenue, Phoenix, Arizona 85009, and its telephone
number is (602) 252-7787.

- ---------------
(1) Does not give effect to the Company's acquisition of B&K Steel on January
    31, 1997, which was accounted for under the purchase method of accounting.
    Accordingly, financial information relating to B&K Steel has not been
    included in periods prior to the acquisition. Giving effect to the
    acquisition of B&K Steel, as if it had occurred on January 1, 1996, the
    Company's pro forma and unaudited revenues, gross profit, income before
    income taxes, pro forma net income (after pro forma income taxes), and pro
    forma net income per share would have been $113,291,000, $18,097,000,
    $10,165,000, $6,099,000, and $1.18, respectively.
 
(2) Prior to this offering, the Company elected to be treated as an S
    corporation under the Internal Revenue Code of 1986, as amended (the
    "Code"). As an S corporation, the Company is not subject to income taxes.
    Pro forma net income reflects the provision for income taxes that would have
    been recorded had the Company been subject to income taxes as a C
    corporation for all periods, assuming an effective tax rate of 40%. Pro
    forma net income does not include credits of $300,000 to income to be
    recorded upon revocation of the Company's subchapter S election. See "S
    Corporation Distribution" and "Management's Discussion and Analysis of
    Financial Condition and Results of Operations."
 
(3) Shares used in the computation of pro forma net income per share are based
    upon a weighted average number of common shares and common stock equivalents
    outstanding during each year. In accordance with Securities and Exchange
    Commission Staff Accounting Bulletin Number 83, all issuances of the
    Company's common stock options at prices below the expected initial public
    offering price during the twelve-month period preceding the proposed
    offering have been treated as common stock equivalents as if they had been
    issued at the Company's inception using the treasury stock method.
 
(4) Backlog is the amount of potential future revenues to be recognized upon
    performance of contracts awarded to the Company. Backlog increases as new
    contract commitments are received, decreases as revenues are recognized, and
    increases or decreases to reflect modifications in the work to be performed
    under a contract. Of the Company's $67.3 million backlog as of December 31,
    1996, approximately $13.1 million was attributable to three projects for a
    single customer in Las Vegas, Nevada, and approximately $34.3 million was
    attributable to the Bank One Ballpark project in Phoenix, Arizona. Of the
    Company's $65.6 million backlog at March 31, 1997, approximately $15.9
    million was attributable to two projects for a single customer in Las Vegas,
    and approximately $26.8 million was attributable to the Bank One Ballpark
    project. See "Management's Discussion and Analysis of Financial Condition
    and Results of Operations" and "Business -- Backlog."
 
(5) Gives effect to (i) the sale of the 2,200,000 shares of Common Stock by the
    Company offered hereby at an assumed initial public offering price of $11.00
    per share and the application of the estimated net proceeds therefrom,
    including payment of the $10.7 million portion of the S Corporation
    Distribution that existed at March 31, 1997 and (ii) an increase to
    stockholders' equity to reflect the recognition of a deferred tax asset, and
    corresponding credit to income, in the amount of $300,000 upon revocation of
    the Company's S corporation election. See "Use of Proceeds," "S Corporation
    Distribution," "Capitalization" and Note 1 to Consolidated Financial
    Statements.

                                  RISK FACTORS
 
     Investment in the Common Stock offered hereby involves certain risks. In
addition to the other information included elsewhere in this Prospectus,
prospective investors should give careful consideration to the following factors
before purchasing shares of the Common Stock offered hereby.
 
DEPENDENCE ON CONSTRUCTION INDUSTRY
 
     The Company earns virtually all of its revenues in the building
construction industry, which is subject to local, regional and national economic
cycles. The Company's revenues and cash flows depend to a significant degree on
major construction projects in various industries, including the hotel and
casino, retail shopping, health care, mining, computer chip manufacturing,
public works and other industries. The failure to obtain major projects, delays
in awards of major projects, or cancellation of major projects could result in
under-utilization of the Company's resources, which would adversely impact the
Company's revenues and cash flows. These factors are largely beyond the control
of the Company. If construction activity declines significantly in the Company's
principal markets, the Company's business, financial condition and results of
operations would be adversely affected.
 
FIXED PRICE CONTRACTS
 
     A substantial portion of the Company's projects currently are performed on
a fixed price basis. In bidding on projects, the Company estimates its costs,
including projected increases in costs of labor, material and services. Despite
these estimates, costs and gross profit realized on a fixed price contract may
vary from estimated amounts because of unforeseen conditions or changes in job
conditions, variations in labor and equipment productivity over the terms of
contracts, higher than expected increases in labor or material costs and other
factors. These variations could have a material adverse effect on the Company's
business, financial condition and results of operations for any period. See
"Business -- Contracting Methods and Performance Bonding."
 
DEPENDENCE ON SUBCONTRACTORS
 
     The Company routinely relies on subcontractors to perform a significant
portion of its fabrication and project detailing to fulfill projects that the
Company cannot fulfill in-house due to capacity constraints or that are in
markets in which the Company has not established a strong local presence. With
respect to these projects, the Company's success depends on its ability to
retain and successfully manage these subcontractors. Any difficulty in
attracting and retaining qualified subcontractors on terms and conditions
favorable to the Company could have an adverse effect on the Company's ability
to complete these projects in a timely and cost effective manner.
 
UNION CONTRACTS
 
     The Company currently is a party to a number of collective bargaining
agreements with various unions representing the Company's fabrication and
erection employees. These contracts expire or are subject to expiration at
various times in the future. The inability of the Company to renew such
contracts could result in work stoppages and other labor disturbances, which
could disrupt the Company's business and adversely affect the Company's results
of operations. See "Business -- Employees."
 
PERCENTAGE OF COMPLETION ACCOUNTING
 
     The Company recognizes revenues using the percentage of completion
accounting method. Under this method, revenues are recognized based on the ratio
that costs incurred to date bear to the total estimated costs to complete the
project. Estimated losses on contracts are recognized in full when the Company
determines that a loss will be incurred. The Company frequently reviews and
revises revenues and total cost estimates as work progresses on a contract and
as contracts are modified. Accordingly, revenue adjustments based upon the
revised completion percentage are reflected in the period that estimates are
revised. Although revenue estimates are based upon management assumptions
supported by historical experience, these estimates could vary materially from
actual results. To the extent percentage of completion adjustments reduce
previously reported revenues, the Company would recognize a charge against
operating results, which could have a
 
                                        8
<PAGE>   10
 
material adverse effect on the Company's results of operations for the
applicable period. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Introduction."
 
GEOGRAPHIC CONCENTRATION
 
     The Company's fabrication and erection operations currently are conducted
primarily in Arizona and Nevada, states in which the construction industry has
experienced substantial growth during recent years. Of the $103.9 million in
revenues earned by the Company in 1996, the Company estimates that approximately
$66.5 million, or 64.0%, of those revenues were related to projects in Arizona
and Nevada. Because of this concentration, the Company's business may be
adversely affected in the event of a downturn in general economic conditions
existing in Arizona and Nevada and in the southwestern United States generally.
See "Business -- Primary Markets and Products."
 
BACKLOG
 
     The Company's backlog can be significantly affected by the receipt, or
loss, of individual contracts. For example, approximately 40.9% of the Company's
$65.5 million backlog at March 31, 1997 was attributable to the Bank One
Ballpark project in Phoenix, Arizona. In the event one or more large contracts
were terminated or their scope reduced, the Company's backlog would decrease
substantially. The Company's future business and results of operations may be
adversely affected if it is unable to replace significant contracts when lost or
completed, or if it otherwise fails to maintain a sufficient level of backlog.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Backlog."
 
OPERATING RISKS
 
     Construction and heavy steel plate weldments involve a high degree of
operational risk. Natural disasters, adverse weather conditions, design,
fabrication and erection errors and work environment accidents can cause death
or personal injury, property damage and suspension of operations. The occurrence
of any of these events could result in loss of revenues, increased costs, and
liability to third parties. Litigation arising from such an occurrence may cause
the Company to be named as a defendant in lawsuits asserting substantial claims.
Although the Company maintains risk management, insurance, and safety programs
intended to prevent or mitigate losses, there can be no assurance that any of
these programs will be adequate or that the Company will be able to maintain
adequate insurance in the future at rates that it considers reasonable. See
"Business -- Legal Proceedings and Insurance."
 
RISKS OF INTERNATIONAL OPERATIONS
 
     The Company is expanding into international markets, with approximately
13.7% of its revenues in 1996 relating to projects outside the United States.
The Company's international operations are subject to certain political,
economic and other uncertainties, including risks of war, nationalization of
assets, renegotiation or nullification of existing contracts, changing political
conditions, changing laws and policies affecting trade and investment, and
overlap of different tax structures. Although the Company currently attempts to
limit its exposure to currency fluctuations by dealing solely in United States
dollars, there can be no assurance that the Company's international operations
will escape the risks of fluctuating currency values, hard currency shortages,
or controls on currency exchange.
 
COMPETITION
 
     Many small and various large companies offer fabrication, erection and
related services that compete with those provided by the Company. Local and
regional companies offer competition in one or more of the Company's geographic
markets or product segments. Out of state or international companies may provide
competition in any market. The Company competes for every project it obtains.
Although the Company believes customers consider, among other things, the
availability and technical capabilities of equipment and personnel, efficiency,
safety record and reputation, price competition usually is the primary factor in
determining which qualified contractor with available equipment is awarded a
contract. Competition has resulted in pressure on pricing and operating margins,
and the effects of competitive pressure in the industry may continue. Some of
the Company's competitors have greater capital and other resources than the
Company and are well established in their respective markets. There can be no
assurance that the Company's
 
                                        9
<PAGE>   11
 
competitors will not substantially increase their commitment of resources
devoted to competing aggressively with the Company or that the Company will be
able to compete profitably with its competitors.
 
SUBSTANTIAL LIQUIDITY REQUIREMENTS
 
     The Company's operations require significant amounts of working capital to
procure materials for contracts to be performed over relatively long periods,
and for purchases and modifications of heavy-duty and specialized fabrication
equipment. In addition, the Company's contract arrangements with customers
sometimes require the Company to provide payment and performance bonds and, in
selected cases, letters of credit, to partially secure the Company's obligations
under its contracts, which may require the Company to incur significant
expenditures prior to receipt of payments. Furthermore, the Company's customers
often will retain a portion of amounts otherwise payable to the Company during
the course of a project as a guarantee of completion of that project. To the
extent the Company is unable to receive project payments in the early stages of
a project, the Company's cash flow would be reduced, which could have a material
adverse effect on the Company's business, financial conditions and results of
operations. See "Management's Discussion and Analysis and Results of
Operations -- Liquidity and Capital Resources."
 
NO ASSURANCE OF SUCCESSFUL ACQUISITIONS
 
     The Company intends to consider acquisitions of and alliances with other
companies in its industry that could complement the Company's business,
including the acquisition of entities in diverse geographic regions and entities
offering greater access to industries and markets not currently served by the
Company. There can be no assurance that suitable acquisition or alliance
candidates can be identified or, if identified, that the Company will be able to
consummate such transactions. Further, there can be no assurance that the
Company will be able to integrate successfully any acquired companies into its
existing operations, which could increase the Company's operating expenses.
Moreover, any acquisition by the Company may result in potentially dilutive
issuances of equity securities, incurrence of additional debt and amortization
of expenses related to goodwill and intangible assets, all of which could
adversely affect the Company's profitability. Acquisitions involve numerous
risks, such as diverting attention of the Company's management from other
business concerns, the entrance of the Company into markets in which it has had
no or only limited experience and the potential loss of key employees of the
acquired company, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Growth Strategy."
 
DEPENDENCE UPON KEY PERSONNEL
 
     The Company's success depends on the continued services of the Company's
senior management and key employees as well as the Company's ability to attract
additional members to its management team with experience in the steel
fabrication and erection industry. The unexpected loss of the services of any of
the Company's key management personnel, or its inability to attract new
management when necessary, could have a material adverse effect upon the
Company. See "Management."
 
POTENTIAL ENVIRONMENTAL LIABILITY
 
     The Company's operations and properties are affected by numerous federal,
state and local environmental protection laws and regulations, such as those
governing discharges to air and water and the handling and disposal of solid and
hazardous wastes. Compliance with these laws and regulations has become
increasingly stringent, complex and costly. There can be no assurance that such
laws and regulations or their interpretation will not change in a manner that
could materially and adversely affect the Company. Certain environmental laws,
such as the Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") and its state law counterparts, provide for strict and joint and
several liability for investigation and remediation of spills and other releases
of toxic and hazardous substances. These laws may apply to conditions at
properties currently or formerly owned or operated by an entity or its
predecessors, as well as to conditions at properties at which wastes or other
contamination attributable to an entity or its predecessors come to be located.
The Company can give no assurance that it, or entities for which it may be
responsible, will not incur such liability in connection with the investigation
and remediation of facilities it currently operates (or formerly owned or
operated) or other locations in a manner that could materially and adversely
affect the Company. See "Business -- Environmental Regulation."
 
                                       10
<PAGE>   12
 
GOVERNMENTAL REGULATION
 
     Many aspects of the Company's operations are subject to governmental
regulations in the United States and in other countries in which the Company
operates, including regulations relating to occupational health and workplace
safety, principally the Occupational Safety and Health Act and regulations
thereunder. Although the Company believes that it is in material compliance with
such laws, there can be no assurance that it will be able to maintain this
status. Further, the Company cannot determine to what extent future operations
and earnings of the Company may be affected by new legislation, new regulations
or changes in or new interpretations of existing regulations. See
"Business -- Governmental Regulation."
 
CONTROL BY MAJORITY STOCKHOLDERS; ABILITY TO ISSUE PREFERRED STOCK
 
     Upon completion of this offering, Mr. David A. Schuff, the Company's
Chairman and co-founder, and Mr. Scott A. Schuff, the Company's President, Chief
Executive Officer, co-founder and a member of its Board of Directors,
collectively will control the voting of approximately 69.4% of the outstanding
Common Stock. As a result, these individuals will control the vote on all
matters requiring approval of the stockholders, including causing or restricting
the sale or merger of the Company. In addition, the Company's Certificate of
Incorporation authorizes the Company to issue shares of "blank check" preferred
stock, the designation, number, voting powers, preferences, and rights of which
may be fixed or altered from time to time by the Board of Directors.
Accordingly, the Board of Directors has the authority, without stockholder
approval, to issue preferred stock with rights that could adversely affect the
voting power or other rights of the holders of the Common Stock. See
"Management," "Principal Stockholders" and "Description of Capital Stock --
Preferred Stock."
 
ABSENCE OF PRIOR MARKET FOR COMMON STOCK; DETERMINATION OF OFFERING PRICE
 
     Prior to this offering, there has been no public trading market for the
Common Stock. Consequently, the price of the Common Stock offered hereby will be
determined through negotiations between the Company and the Representative. In
addition, there can be no assurance that a regular trading market for the Common
Stock will develop after this offering or that, if developed, any such market
will be sustained. See "Underwriting."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The stock market has experienced price and volume fluctuations that have
affected the market for many companies and have often been unrelated to the
operating performance of such companies. The market price of the Common Stock
could also be subject to significant fluctuations in response to variations in
the Company's quarterly operating results, analyst reports, announcements
concerning the Company, legislative or regulatory changes in the interpretation
of existing statutes or regulations affecting the Company's business,
litigation, general trends in the industry and other events or factors.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     There will be 7,200,000 shares of Common Stock outstanding upon
consummation of this offering (assuming no exercise of the over-allotment option
granted to the Underwriters). Of these shares, 2,200,000 shares of Common Stock
will be freely tradeable. The 5,000,000 remaining shares of Common Stock are
beneficially held by Messrs. David A. Schuff and Scott A. Schuff who, together
with the Company, have agreed not to sell, contract to sell or otherwise dispose
of any shares of Common Stock without the consent of the Representative for a
period of 180 days after the date of this Prospectus. Upon expiration of these
agreements, these shares will be eligible for sale in the public markets subject
to the notice, manner of sale, volume limitations, and current public reporting
requirements imposed by Rule 144 ("Rule 144") promulgated under the Securities
Act of 1933, as amended (the "Securities Act"). Sales of substantial amounts of
Common Stock in the open market, or the availability of such shares for sale
following this offering, could adversely affect the prevailing market price of
the Common Stock and may make it more difficult for the
 
                                       11
<PAGE>   13
 
Company to sell its equity securities in the future on terms it deems
appropriate. See "Shares Eligible for Future Sale," "Principal Stockholders" and
"Underwriting."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
     Purchasers of Common Stock offered hereby will suffer immediate and
substantial dilution in the net tangible book value of the Common Stock from the
initial public offering price. See "Dilution."
 
FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS
 
     This Prospectus contains forward-looking statements including statements
regarding, among other items, the Company's business strategy, growth strategy,
and anticipated trends in the Company's business. Additional written or oral
forward-looking statements may be made by the Company from time to time in

                                  THE COMPANY
 
     Founded in 1976, the Company initially operated primarily as a steel
erector on commercial and industrial building projects and subcontracted steel
fabrication services to others. Due to a sharp increase in commercial and
industrial construction activity in the 1980's, many of the Company's
fabrication subcontractors could not meet the increased demand for steel
fabrication services and raised prices to the Company. In August 1985, the
Company acquired the assets of Marathon Steel Company, a Phoenix, Arizona-based
steel fabrication contractor. The acquisition of Marathon Steel Company enabled
the Company to become less dependent on steel fabrication subcontractors and to
continue its pursuit of large, more complicated construction projects.
 
     The Company is a fully integrated fabricator and erector of structural
steel and heavy steel plate. The Company fabricates and erects structural steel
for commercial and industrial construction projects such as high and low rise
buildings and office complexes, hotels and casinos, convention centers, sports
arenas, shopping malls, hospitals, dams, bridges, mines and power plants. The
Company also specializes in the fabrication and erection of heavy steel plate,
including large diameter water pipe, water storage tanks, pollution control
scrubbers, tunnel liners, pressure vessels, and a variety of customized
projects. The Company seeks to differentiate its operations by offering
complete, turnkey steel construction services featuring engineering, detailing,
shop fabrication and field erection. By offering an integrated package of steel
construction services from a single source, the Company is able to respond more
efficiently to the design and construction challenges associated with large,
complex, "fast track" construction projects.
 
     The Company was incorporated in Arizona in 1976 and was reincorporated in
Delaware in 1997. The Company's principal executive offices are located at 420
South 19th Avenue, Phoenix, Arizona 85009, and its telephone number is (602)
252-7787.

                           S CORPORATION DISTRIBUTION
 
     Since 1987, the Company has been subject to taxation under subchapter S of
the Code. As a result, the taxable income of the Company has been attributed and
taxed directly to the Company's stockholders, rather than to the Company.
Historically, the Company has not distributed all of its taxable income. Amounts
in excess of estimated stockholder tax liabilities and certain other
distributions have been retained as working capital and used to support business
operations.
 
     The following table sets forth the Company's taxable income and accrued
distributions from the date of its S corporation election in 1987 through March
31, 1997:
 
<TABLE>
        <S>                                                              <C>
        Taxable income.................................................   $26.1 million
        Less: Distributions accrued and paid through March 31, 1997....    10.6 million
        Less: Distributions accrued but unpaid at March 31, 1997.......     4.8 million
                                                                          -------------
        Undistributed taxable income at March 31, 1997.................   $10.7 million
                                                                          =============
</TABLE>
 
     Undistributed taxable income is estimated to increase from $10.7 million at
March 31, 1997 to $12.0 million at the closing of this offering. A distribution
payable to stockholders equal to all remaining undistributed taxable income will
be accrued and paid in connection with the closing of this offering, reducing
the retained earnings of the Company to an estimated $1.6 million. This
distribution will be paid from the proceeds of this offering (the "S Corporation
Distribution"). Purchasers of shares in this offering will not receive any of
this distribution. See "Use of Proceeds" and "Capitalization."
 
     The Company intends to revoke its S corporation election prior to the
closing of this offering. Upon revocation of its S corporation election, the
Company will become subject to income taxation and, in connection therewith, the
Company will record a deferred tax asset of $300,000 in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and Note 1 to Consolidated Financial Statements.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,200,000 shares of
Common Stock offered hereby, after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company (including
amounts payable to the Company's financial consultant), are estimated to be
approximately $21.8 million ($25.2 million if the Underwriters' over-allotment
option is exercised in full) based upon an assumed initial public offering price
of $11.00 per share. The Company anticipates that such net proceeds will be used
as follows: (i) approximately $12.0 million to fund the S Corporation
Distribution; (ii) approximately $2.5 million to purchase specialized
fabrication equipment; and (iii) the balance for general corporate purposes,
including, when and if available, the acquisition of businesses complementary to
the Company's business and growth strategy. The Company has no pending
commitments for and is not engaged in negotiations in connection with any
acquisitions. See "S Corporation Distribution."
 
     Until applied as set forth above, all proceeds will be invested in
short-term, interest bearing, investment grade or equivalent securities or bank
certificates of deposit. Investment of the net proceeds in short-term
investments rather than operations could adversely affect the Company's overall
return on its capital.
 
                                DIVIDEND POLICY
 
     Except for the distributions described in "Use of Proceeds" and "S
Corporation Distribution" above, the Company intends to retain earnings to
finance the operations and expansion of the Company's business and does not
anticipate paying cash dividends on its Common Stock in the foreseeable future.
See "Description of Capital Stock."

                                 CAPITALIZATION
 
     The following table sets forth the actual capitalization of the Company as
of March 31, 1997, and the pro forma as adjusted amounts, which reflect (i) the
sale of the 2,200,000 shares of Common Stock offered hereby at an assumed
initial public offering price of $11.00 per share, after deducting the
underwriting discount and estimated offering expenses, (ii) the application of
the estimated net proceeds therefrom, including payment of the $10.7 million
portion of the S Corporation Distribution that existed at March 31, 1997 and
(iii) an increase in retained earnings to reflect recognition of a deferred tax
asset and corresponding credit to income in the amount of $300,000 upon
revocation of the Company's S corporation election. See "Use of Proceeds," "S
Corporation Distribution," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Note 1 to Consolidated Financial
Statements. The table should be read in conjunction with the Company's
Consolidated Financial Statements and Notes thereto included elsewhere in this

                                    DILUTION
 
     The net tangible book value of the Company's Common Stock at March 31, 1997
was $11.3 million, or $2.27 per share of Common Stock. Net tangible book value
per common share represents the book value of the Company's tangible assets less
total liabilities divided by the number of shares of Common Stock outstanding.
At March 31, 1997, the Company had $10.7 million of undistributed taxable
income. If such amount had been distributed on that date, the Company's pro
forma tangible net book value would have been $600,000, or $0.13 per share.
 
     Without taking into account any changes in such net tangible book value
subsequent to March 31, 1997, other than to give effect to (i) the sale by the
Company of 2,200,000 shares of Common Stock offered hereby (after deducting the
underwriting discount and estimated offering expenses) and the application of
the estimated proceeds thereof, including payment of the March 31, 1997 portion
of the S Corporation Distribution, and (ii) an increase in retained earnings to
reflect the recognition of a deferred tax asset, and corresponding credit to
income, in the amount of $300,000 upon revocation of the Company's S corporation
election, the pro forma net tangible book value of the Company as of March 31,
1997 would have been $22.8 million, or $3.16 per share. This represents an
immediate increase in net tangible book value of $3.03 per share to current
stockholders and immediate dilution of $7.84 per share to new investors
purchasing Common Stock pursuant to this offering. Dilution per share to new
investors represents the difference between the amount per share paid by
purchasers of Common Stock of the Company pursuant to this offering and the pro
forma net tangible book value per share of Common Stock immediately after
completion of this offering. The following table illustrates the per share
effect of this dilution on an investor's purchase of shares:

</TABLE>
 
     The foregoing table excludes up to 330,000 shares of Common Stock that may
be sold by the Company upon the exercise of the Underwriters' over-allotment
option. The table also excludes 345,500 shares of Common Stock issuable upon
exercise of stock options granted under the Company's 1997 Stock Option Plan at
an exercise price of $5.00 per share and 22,500 shares of Common Stock issuable
upon exercise of stock options to be granted to the Company's non-employee
directors upon their appointment to the Board of Directors at the closing of
this offering with an exercise price equal to the initial public offering price.
Assuming the exercise of all such options, the pro forma net tangible book value
per share before this offering would be $0.49, the pro forma net tangible book
value per share after this offering would be $3.27, and the dilution per share
to new investors would be $7.73. See "Description of Capital Stock,"
"Underwriting" and "Management."

(1) Does not give effect to the Company's acquisition of B&K Steel on January
    31, 1997, which was accounted for under the purchase method of accounting.
    Accordingly, financial information relating to B&K Steel has not been
    included in periods prior to the acquisition. Giving effect to the
    acquisition of B&K Steel as if it had occurred on January 1, 1996, the
    Company's pro forma and unaudited revenues, gross profit, income before
    income taxes, pro forma net income (after pro forma income taxes), and pro
    forma net income per share would have been $113,291,000, $18,097,000,
    $10,165,000, $6,099,000, and $1.18, respectively.
 
(2) Prior to this offering, the Company elected to be treated as an S
    corporation under the Code. As an S corporation, the Company is not subject
    to income taxes. Pro forma net income reflects the provision for income
    taxes that would have been recorded had the Company been subject to income
    taxes as a C corporation for all periods, assuming an effective tax rate of
    40%. Pro forma net income does not include projected credits of $300,000 to
    income to be recorded upon revocation of the Company's S corporation
    election. See "S Corporation Distribution" and "Management's Discussion and
    Analysis of Financial Condition and Results of Operations."
 
(3) Shares used in the computation of pro forma net income per share are based
    upon the weighted average number of common shares and common stock
    equivalents outstanding during each year. In accordance with Securities and
    Exchange Commission Staff Accounting Bulletin Number 83, all issuances of
    the Company's common stock options at prices below the expected initial
    public offering price during the twelve-month period preceding the proposed
    offering have been treated as common stock equivalents as if they had been
    issued at the Company's inception using the treasury stock method.
 
(4) Backlog is the amount of potential future revenues to be recognized upon
    performance of contracts awarded to the Company. Backlog increases as new
    contract commitments are received, decreases as revenues are recognized, and
    increases or decreases to reflect modifications in the work to be performed
    under a contract. Of the Company's $67.3 million backlog as of December 31,
    1996, approximately $13.1 million was attributable to three projects for a
    single customer in Las Vegas, Nevada, and approximately $34.3 million was
    attributable to the Bank One Ballpark project in Phoenix, Arizona. Of the
    Company's $65.6 million backlog at March 31, 1997, approximately $15.9
    million was attributable to two projects for a single customer in Las Vegas,
    and approximately $26.8 million was attributable to the Bank One Ballpark
    project. See "Management's Discussion and Analysis of Financial Condition
    and Results of Operations" and "Business -- Backlog."
 
(5) Restricted funds on deposit represent funds on deposit in an interest
    bearing escrow account which are maintained in lieu of retention for a
    specific contract. Retentions on contract receivables are amounts due which
    are withheld until the completed project has been accepted by the customer
    in accordance with the contract. See Note 1 to Consolidated Financial
    Statements.
 
(6) The Company recognizes revenues and costs from construction projects using
    the percentage of completion accounting method. Under this method, revenues
    are recognized based upon the ratio of the costs incurred to date to the
    total estimated costs to complete the project, commencing when progress is
    sufficient to estimate final results with reasonable accuracy, which
    typically occurs when fabricated product is shipped to the project site or
    when erection of the project commences. Construction contracts with
    customers generally provide that billings are to be made monthly in amounts
    which are commensurate with the extent of performance under the contracts.
    Costs and recognized earnings in excess of billings on uncompleted contracts
    primarily represent revenues earned under the percentage of completion
    method which have not been billed, and also include costs incurred in excess
    of billings on contracts for which sufficient work has not been performed to
    allow for recognition of revenues. Billings in excess of costs and
    recognized earnings on uncompleted contracts represent amounts billed on
    contracts in excess of the revenues allowed to be recognized under the
    percentage of completion method on those contracts.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis provides information regarding the
Company's financial position as of December 31, 1995 and 1996 and March 31, 1996
and 1997, and its results of operations for the years ended December 31, 1994,
1995, and 1996 and the three months ended March 31, 1996 and 1997. This
discussion should be read in conjunction with the preceding "Selected
Consolidated Financial and Operating Data" and the Company's Consolidated
Financial Statements and related Notes thereto and other financial data
appearing elsewhere in this Prospectus. Results of operations for interim
periods are not necessarily indicative of results to be expected for the full
fiscal year. For information relating to factors that could affect future
operating results, see "Risk Factors." Any forward-looking statements included
in this section or elsewhere in the Prospectus should be considered in light of
such risk factors, as well as the information set forth below and in other
portions of the Prospectus, any of which could cause the Company's actual
results to differ materially from those discussed herein.
 
INTRODUCTION
 
     The Company's results of operations are affected primarily by (i) the level
of commercial and industrial construction in its principal markets, (ii) the
Company's ability to win project contracts, (iii) the amount and complexity of
project changes requested by customers or general contractors, (iv) the
Company's success in utilizing its resources at or near full capacity, and (v)
the Company's ability to complete contracts on a timely and cost effective
basis. The level of commercial and industrial construction activity is related
to several factors, including local, regional and national economic conditions,
interest rates, availability of financing, and the supply of existing facilities
relative to demand.
 
     The Company has observed a trend in the steel fabrication and erection
industry toward large, complex, fast track, "design-as-you-go" projects. These
projects are well-suited to integrated contractors that can (i) reduce the
logistical and coordination problems inherent in the use of multiple
subcontractors to complete a large, complex project and (ii) more efficiently
respond to rapid and multiple design changes while minimizing project delays and
cost overruns commonly associated with such changes. The complexity and size of
these projects requires subcontractors possessing extended financial and
operational capabilities. Typically, these projects offer greater potential
profit than small, less complex projects because project management and overhead
requirements for large projects usually are proportionately less. Individual
large projects can have a substantial impact upon the Company's results of
operations and cause significant fluctuations from quarter to quarter.
 
     The Company obtains contracts through competitive bidding or negotiation,
which generally are either fixed price or cost-plus arrangements. Historically,
most of the Company's work is performed on a fixed price basis. In bidding or
negotiating contracts, the Company must estimate its costs, including projected
increases in labor, material, and services costs. Project duration typically
lasts from three to twelve months.
 
     The Company recognizes revenues using the percentage of completion
accounting method. Under this method, revenues are recognized based upon the
ratio of costs incurred to date to the estimated total cost to complete the
project. Revenue recognition begins when progress is sufficient to estimate
final results with reasonable accuracy, which typically occurs when fabricated
product is shipped to the project site or when erection of the project
commences. Revenues relating to changes in the scope of a contract are
recognized when the customer has authorized the change, the work is commenced
and the Company has made an estimate of the amount that will be paid for the
change. The cumulative impact of revisions in total cost estimates during the
progress of work is reflected in the period in which these revisions become
known. Estimated losses on contracts are recognized in full when it is
determined that a loss will be incurred on a contract.
 
     Cost of revenues consists of the costs of materials, equipment, direct
labor, fringe benefits, and indirect costs associated with detailing,
fabrication and erection, including rent, depreciation and supervisory labor.
Other costs not associated with specific projects are included in general and
administrative expenses.
 
                                       20

     Gross profit margins can be positively affected by large, more complex
projects, the percentage of negotiated contracts relative to competitively bid
contracts, the number and scope of contract modifications, and improvements in
operating efficiencies. Gross profit margins can be adversely affected by
construction delays, inefficient or under-utilization of the Company's
resources, availability and cost of materials and labor, the timing and
performance of work by other contractors, weather conditions, and construction
site conditions.
 
     Backlog increases as contract commitments are obtained, decreases as
revenues are recognized, and increases or decreases to reflect modifications in
the work to be performed under the contract. The timing of contract commitments,
the size of projects and other factors beyond the Company's control can cause
significant fluctuation in backlog outstanding at any given date.
 
     The Company presently is taxed as an S corporation for income tax purposes.
Accordingly, its income is taxed directly to its stockholders. Prior to the
completion of this offering, the Company's S corporation election will be
revoked and thereafter the Company will be subject to income tax as a C
corporation. For purposes of the financial information contained in this
section, pro forma income tax expense has been included assuming an income tax
rate of 40%, and pro forma net income reflects this provision.

</TABLE>
 
     THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31,
1996
 
     Revenues.  Revenues increased by 145.0% to $25.5 million for the three
months ended March 31, 1997 from $10.4 million for the three months ended March
31, 1996. The increase was attributable primarily to a greater number of large
individual contracts in 1997 as compared to 1996 and to an unusually low revenue
quarter for 1996 due to the Company being in the early stages of large contracts
for which revenue recognition had not begun. The revenues in the period ended
March 31, 1997 also included two months of revenues of B&K Steel following its
acquisition by the Company on January 31, 1997. The average revenues for the
Company's ten largest revenue generating projects in the three month period
ended March 31, 1997 was $2.0 million versus $850,000 in the three month period
ended March 31, 1996. One contract, relating to Bank One Ballpark, produced
revenues of $9.0 million for the first quarter of 1997. The largest contract in
progress during the three month period ended March 31, 1996 contributed only
$2.7 million to revenues earned in that quarter.
 
     Gross profit.  Gross profit increased by 93.4% to $3.9 million for the
three months ended March 31, 1997 from $2.0 million for the three months ended
March 31, 1996. The increase was attributable primarily to a 145.0% increase in
revenues. As a percentage of revenues, gross profit declined to 15.1% in 1997
from 19.1% in 1996 due to above-average 1996 margins from higher than
anticipated revenues from requested contract modifications.

     General and administrative expenses.  General and administrative expenses
increased by 53.4% to $2.1 million for the three months ended March 31, 1997
from $1.4 million for the three months ended March 31, 1996. General and
administrative expenses as a percentage of revenues decreased to 8.2% in 1997
from 13.0% in 1996 due to the 145.0% increase in revenues and a less than
proportionate increase in general and administrative expenses required to
support the increase in revenues. The Company believes that it currently has
sufficient management and administrative resources to support continued growth
in revenues without a proportionate increase in general and administrative
expenses.
 
     Interest expense.  Interest expense decreased by 35.4% to $95,000 for the
three months ended March 31, 1997 from $147,000 for the three months ended March
31, 1996. The decrease was attributable to the lower average line of credit
borrowings, which was made possible by the Company's ability to increase its
billings in excess of costs and recognized earnings on uncompleted contracts.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     Pro forma net income.  Pro forma net income increased by 226.8% to $1.1
million for the three months ended March 31, 1997 from $325,000 for the three
months ended March 31, 1996.
 
     Backlog.  Backlog at March 31, 1997 was $60.5 million less than at March
31, 1996. Backlog at March 31, 1996 was unusually high due to the receipt of
five contracts, each in excess of $10.0 million, during the fourth quarter of
1995 and the first quarter of 1996. These contracts produced backlog totalling
$86.5 million at March 31, 1996, $50.0 million of which was attributable to the
first and second phases of the Bank One Ballpark project. Backlog at March 31,
1997 included $26.8 million relating to the second and third phases of the Bank
One Ballpark project. The Company's backlog at March 31, 1997 also reflected
approximately $15.9 million attributable to two projects for a single customer
in Las Vegas.
 
     YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Revenues.  Revenues increased by 67.4% to $103.9 million in 1996 from $62.1
million in 1995. The increase was attributable primarily to larger individual
contracts in 1996 compared to 1995, including the Bank One Ballpark, which
contributed $19.8 million. The Bank One Ballpark project is expected to generate
total revenues approaching $55.0 million when completed in 1998. The average
revenues for the Company's ten largest revenue generating projects was $7.8
million in 1996 versus $3.3 million in 1995. Excluding Bank One Ballpark, the
ten largest revenue generating projects averaged $6.4 million in 1996, which
represented a 93.9% increase over the 1995 average of $3.3 million.
 
     Gross profit.  Gross profit increased by 115.0% to $16.9 million in 1996
from $7.9 million in 1995 primarily due to the 67.4% increase in revenues. As a
percentage of revenues, gross profit increased to 16.3% in 1996 from 12.7% in
1995. The increase as a percentage of revenues was attributable primarily to
greater overhead absorption, better pricing associated with larger projects,
improved operating efficiencies, and modifications to specific contracts.
 
     General and administrative expenses.  General and administrative expenses
increased by 27.1% to $6.7 million in 1996 from $5.3 million in 1995. Of the
$1.4 million increase in 1996, $590,000 was attributable to bonus payments to
employees and $529,000 was attributable to a deferred compensation plan
implemented in 1996. The Company's deferred compensation plan was terminated in
1997. General and administrative expenses as a percentage of revenues decreased
to 6.5% in 1996 from 8.5% in 1995 due to the benefits of having larger average
contracts in 1996. In 1995, the Company experienced a 9.0% decrease in revenues
from 1994 and elected not to reduce general and administrative costs
proportionately in anticipation of future contract awards, thereby causing
higher general and administrative expenses as a percentage of revenues.
 
     Interest expense.  Interest expense decreased by 39.9% to $452,000 in 1996
from $752,000 in 1995. The decrease was attributable to the lower average line
of credit borrowings, which reflected in large part the Company's ability to
increase its billings in excess of costs and recognized earnings on uncompleted
contracts. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
                                       22
<PAGE>   24
 
     Pro forma net income.  Pro forma net income increased by 310.2% to $6.0
million in 1996 from $1.5 million in 1995.
 
     Backlog.  Backlog at December 31, 1996 was $13.5 million less than at
December 31, 1995 due to the receipt of four contract awards that collectively
represented backlog of $47.2 million at December 31, 1995. Additionally, the
high level of backlog at the end of the first quarter of 1996 caused the Company
to become more selective in the pursuit of new contract awards during the
remainder of the year. Of the backlog at December 31, 1996, approximately $13.1
million was attributable to three projects for a single customer in Las Vegas,
Nevada, and approximately $34.3 million was attributable to the Bank One
Ballpark project in Phoenix, Arizona.
 
     YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Revenues.  Revenues decreased by 9.0% to $62.1 million in 1995 from $68.2
million in 1994. The decrease was attributable primarily to the completion of
two large construction projects during 1994, delays in commencing work on
certain new projects, and a focus on certain targeted projects that did not
materialize. The average revenues for the Company's ten largest revenue
generating projects was $3.3 million in each of 1995 and 1994.
 
     Gross profit.  Gross profit decreased by 15.6% to $7.9 million in 1995 from
$9.3 million in 1994. As a percentage of revenues, gross profit decreased to
12.7% in 1995 from 13.7% in 1994 due primarily to the decrease in revenues
coupled with the relatively fixed nature of certain expenses.
 
     General and administrative expenses.  General and administrative expenses
increased by 7.5% to $5.3 million in 1995 from $4.9 million in 1994. General and
administrative expenses as a percentage of revenues increased to 8.5% in 1995
from 7.2% in 1994. In 1995, the Company experienced a 9.0% decrease in revenues
from 1994 and elected not to reduce general and administrative costs
proportionately in anticipation of future contract awards, thereby causing
higher general and administrative expenses as a percentage of revenues.
 
     Interest expense.  Interest expense increased by 4.7% to $752,000 in 1995
from $718,000 in 1994. The increase was attributable to slightly higher average
amounts outstanding on the Company's revolving line of credit.
 
     Pro forma net income.  Pro forma net income decreased by 34.9% to $1.5
million in 1995 from $2.3 million in 1994.
 
     Backlog.  Backlog at December 31, 1995 was $58.3 million greater than at
December 31, 1994 due to the receipt of four contract awards totalling $47.2
million in the fourth quarter of 1995.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company attempts to structure the payment arrangements under its
contracts to match costs incurred under the project. To the extent the Company
is able to bill in advance of costs incurred, it generates working capital
through billings in excess of costs and recognized earnings on uncompleted
contracts. To the extent the Company is not able to bill in advance of costs, it
relies on its credit facilities to meet its working capital needs. At March 31,
1997, the Company had no borrowings under its line of credit due in large part
to its billings in excess of costs and recognized earnings on uncompleted
contracts of $22.4 million. At March 31, 1997, the Company had working capital
of approximately $8.6 million. The Company believes that it has sufficient
liquidity through its present resources and the existence of its bank credit
facility to meet its near term financial needs.
 
     The Company's short term cash needs are primarily for working capital to
support operations including receivables, inventories, and other costs incurred
in performing its contracts. Operating activities provided cash flows of
$251,000 for the three months ended March 31, 1997 and $14.4 million for the
year ended December 31, 1996. For the first quarter of 1997, operating cash
flows were less than net income due to increased working capital requirements.
For the year ended December 31, 1996, operating cash flows were greater than net
income (excluding pro forma income taxes) due to favorable billings relating to
contracts in process. Investing activities required $705,000 for the three
months ended March 31, 1997 and $2.3 million during the year ended December 31,
1996, substantially all of which were related to purchases of property and
equipment and the cash portion of the acquisition of B&K Steel. Financing
activities consumed $2.0 million for the three months ended March 31, 1997 and
$5.1 million for the year ended December 31, 1996, which were related primarily
to repayments of long-term debt and line of credit balances. Also included in
financing activities were distributions to stockholders for income taxes related
to the operations of the business and other stockholder distributions. These
distributions totaled $776,000 for the three months ended March 31, 1997 and
$2.3 million for the year ended December 31, 1996. Other than the S Corporation
Distribution, the Company does not anticipate paying any future dividends. See
"Dividend Policy."
 
     The Company has a credit facility with a commercial bank that is subject to
renewal on June 30, 1998 and is collateralized by contract receivables,
equipment and inventory. This agreement permitted the Company to borrow up to an
amount equal to 75% of qualifying contracts receivable, but in no event less
than $1.0 million. The Company recently modified its line of credit to increase
its minimum borrowing capacity to $2.5 million through July 31, 1997. The
Company is in the process of renegotiating the terms of this credit facility,
including its minimum borrowing capacity. The Company's ability to borrow up to
$6.5 million is subject to, among other restrictions, billings in excess of cost
and recognized earnings on uncompleted contracts. As of March 31, 1997, other
than the $1.0 million minimum, there was no additional credit available under
the line for future borrowings due to the high level of billings in excess of
costs and recognized earnings on uncompleted contracts. The Company also
maintains an equipment financing line of credit pursuant to which it may borrow
up to $500,000.
 
     The Company has two other long-term debt commitments that are related to
its property and equipment. One is a subordinated note payable to a limited
partnership comprised of the Company's present stockholders and certain of their
family members, which requires monthly payments of $12,037 plus interest and
matures in 1999. The balance on this loan was approximately $2.3 million at
March 31, 1997. The other long-term debt of the Company consists of two notes in
the aggregate principal amount of $796,250 incurred as part of the consideration
paid to the sellers in the B&K Steel acquisition. Such notes are payable in five
equal annual installments ending in 2002. The acquisition of B&K Steel, which
had 1996 revenues of approximately $9.4 million, was accounted for under the
purchase method of accounting. The fair value for the tangible net assets
acquired approximated the purchase price so no goodwill was recorded with
respect to the transaction.
 
     The Company leases its fabrication and office facilities from a partnership
in which the present beneficial stockholders of the Company and their family
members are the general and limited partners. Under the lease for the Company's
principal fabrication and office facilities, the Company's annual rental
payments were $264,000 in 1996, increasing to $292,000 for 1997, $414,000 for
1998, $556,000 for 1999, $601,000 in 2000, and $605,000 in each year thereafter
during the 20 year term of the lease. The lease agreement for the B&K Steel
property and equipment provides for rental payments in the amount of $340,000
per year over the 20
 
                                       25

year term of the lease. The Company also leases additional office facilities
adjacent to the Company's existing principal office and shop facilities. This
office lease provides for rental payments of $135,000 per year over the 20 year
term of the lease. See "Business -- Properties" and "Certain Relationships and
Related Transactions."
 
     The Company estimates that its capital expenditures for 1997 will be
approximately $2.5 million. The Company believes that its available funds, cash
generated by operating activities and funds available under its bank credit
facility will be sufficient to fund these capital expenditures and its working
capital needs. However, the Company may expand its operations through future
acquisitions and may require additional equity or debt financing. If the Company
engages in any acquisitions, it may be required to obtain additional debt or
equity financing. See "Risk Factors -- Substantial Liquidity Requirements."
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
     Statements of Financial Accounting Standards No. 123, "Accounting for Stock
Based Compensation" (FAS 123), establishes a fair value method of accounting for
stock based compensation plans and for transactions in which an entity acquires
goods or services from non-employees in exchange for equity instruments. The
Company adopted this standard effective January 1, 1996. FAS 123 encourages, but
does not require, companies to record compensation costs for stock based
employee compensation. The Company has chosen to account for stock based
compensation to employees utilizing the intrinsic value method of Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees."
Accordingly, compensation costs for stock options is measured as the excess, if
any, of the fair market value of the Company's stock at the date of grant over
the amount an employee must pay to acquire the stock. The Company's first stock
option grants were made in February 1997, thereby making the standards
applicable to the quarter ended March 31, 1997. The grants were made at amounts
that management believes equal the fair value of its Common Stock at the date of
grant and, accordingly, no compensation expense was required.
 
     Statement of Financial Accounting Standards No. 128, "Earnings Per Share"
(FAS 128), issued by the Financial Accounting Standards Board in February 1997,
is effective for periods ending after December 15, 1997. At that time, the
Company will be required to change the method currently used to compute earnings
per share and to restate all prior periods. Under the new requirements for
calculating primary earnings per share, the dilutive effect of stock options
will be excluded. The impact is expected to result in an increase in pro forma
primary earnings per share for the year ended December 31, 1996 of $0.05 and for
the quarters ended March 31, 1996 and March 31, 1997 of $0.00 and $0.01,
respectively. The impact of FAS 128 on the calculation of fully diluted pro
forma earnings per share for these periods is not expected to be material.

                                    BUSINESS
 
GENERAL
 
     The Company is a rapidly growing steel fabrication and erection company
that provides a fully integrated range of steel construction services.
Engineering News Record, a professional trade publication, ranked the Company
the second largest steel erection subcontractor in the United States based on
1995 revenues and the largest steel erection subcontractor in the United States
based on 1994 revenues. The Company seeks to differentiate its operations by
offering complete, turnkey steel construction services featuring engineering,
detailing, shop fabrication and field erection. By offering a single source of
steel construction services, the Company is able to respond more efficiently to
the design and construction challenges associated with large, fast track,
"design-as-you-go" construction projects.
 
     The Company's services are employed in the construction of a variety of
commercial and industrial structures, such as hotels and casinos, office
buildings, hospitals, manufacturing plants, mining facilities, shopping malls,
sports stadiums, power plants, bridges, large diameter water pipes and other
public works projects. Its customers include general contractors, project
owners, engineering firms, mine operators and various governmental entities. The
Company operates primarily in the southwestern United States with a
concentration in Arizona, Nevada, and southern California, and is expanding its
operations in South America and Mexico.
 
     The Company has experienced significant growth in revenues and pre-tax
income over the past five years. Revenues have more than doubled from $47.0
million in 1992 to $103.9 million ($113.3 million giving pro forma effect to the
1997 B&K Steel acquisition) in 1996. During that same period, pre-tax income has
grown at a compound annual growth rate of 101.5%, from $610,000 in 1992 to $10.1
million in 1996.
 
OVERVIEW OF INDUSTRY
 
     Companies engaged in the steel fabrication and erection industry prepare
detailed shop drawings, fabricate and erect structural steel and steel plate
weldments, and perform related engineering services for the construction of
various facilities. The primary customers for these services include private
developers, general contractors, engineering firms, and governmental agencies
involved in a variety of large scale construction projects. Historically, these
customers have relied on multiple subcontractors to perform various services to
complete a single project, primarily because few companies in this industry
offer fully integrated engineering, detailing, fabrication and erection
services.
 
     The Company believes that there is an increasing trend in the construction
industry toward complex, fast track, "design-as-you-go" projects. This trend is
largely driven by the desire of project owners to more quickly secure the
benefits of revenue producing projects, such as casinos, mines and computer chip
plants. These projects require that all phases of construction be accomplished
in accordance with compressed time schedules. Further, because many construction
activities are dependent on the progress of steel erection, timely completion of
this phase is critical. These projects also are characterized by numerous design
changes requiring that all construction participants coordinate their efforts in
order to respond quickly and efficiently in implementing these changes. These
trends have created a demand for fully integrated fabrication and erection
contractors that can (i) avoid the coordination difficulties inherent in the use
of multiple subcontractors and (ii) implement rapid and multiple design changes
in a coordinated and timely manner, preventing project delays and reducing costs
to the general contractor or owner. The Company believes that it has gained a
reputation in the industry as a reliable, fully integrated provider of
engineering, detailing, fabrication, and erection services with the ability to
complete large, complex projects on a timely, cost efficient basis.
 
     The Company also believes that the steel fabrication and erection industry
is highly fragmented and that many of its competitors are small businesses
operating in local or regional markets. Given the trend toward the use of fully
integrated contractors and the large number of smaller companies engaged in this
industry, the Company believes the industry may experience consolidation.

BUSINESS STRATEGY
 
     The Company's objective is to achieve and maintain a leading market
position in each of its geographic and specific product markets. The Company
believes that its track record of providing quality services on a timely basis
has enabled it to garner a dominant share of the primary geographic markets
served by it and to increase its market share of large, fast track projects in
markets in which it maintains a significant presence. The Company will continue
to pursue its objective by implementing a strategy comprised of the following
components:
 
          Promote Coordinated Service Capabilities.  The Company promotes its
     ability to provide a fully integrated range of engineering, detailing,
     fabrication, and erection services, which enables the Company to compete
     more effectively on large, "design-as-you-go" projects that typically offer
     more favorable contract terms. The Company believes it is positioned to
     capitalize on industry trends toward construction of large, fast track
     projects incorporating numerous design changes, and the increasing demand
     for fully integrated fabrication and erection contractors capable of both
     implementing those design changes in a timely and cost efficient manner and
     providing overall project management capabilities.
 
          Emphasize Innovative Services.  The Company focuses its engineering,
     detailing, fabrication and erection expertise on distinct product segments
     requiring unique or innovative techniques, where the Company typically
     experiences less competition and more advantageous negotiated contract
     opportunities. The Company has extensive experience in providing services
     requiring complex fabrication and erection techniques and other unusual
     project needs, such as specialized transportation, steel treatment or
     specialty coating applications. These service capabilities have enabled the
     Company to address such design sensitive projects as computer chip
     manufacturing facilities, large diameter underground water pipes, and
     uniquely designed hotels and casinos.
 
          Diversify Customer and Product Base.  Although the Company seeks to
     garner a leading share of the geographic and product markets in which it
     competes, it also seeks to diversify its construction projects across a
     wide range of commercial, industrial, and specialty projects. The following
     chart sets forth the percentage of revenues attributable to the Company's
     various geographic and project markets for 1996:

</TABLE>
 
          In recent periods, the Company has focused efforts on diversifying
     into international markets. Accordingly, the Company believes that its
     combined diversification into new geographic, specific product and
     international markets will better enable it to expand its revenue base and
     to reduce the impact of periodic market or economic conditions adversely
     impacting one or more of its market segments.
 
          Employ Unique Technical Expertise.  The Company offers in-house
     project management and design expertise not typically provided by steel
     fabricators and erectors. The Company employs two registered structural
     engineers and approximately 30 design and detailing personnel, which
     permits the Company to occupy a more influential role in critical design
     decisions on many projects. The Company believes that its ability to offer
     these services allows it to negotiate rather than bid on a greater
     percentage of its contracts, which enables the Company to obtain terms more
     favorable to it than the terms of competitively bid projects, while at the
     same time providing overall cost savings and project efficiencies to its
     customers. The Company's technical expertise also permits it to compete
     more effectively for projects offering unique structural or design
     challenges, such as the fully retractable roof on the Bank One Ballpark,
     the Salt River Siphon Replacement Project, and specialty coating of large
     diameter water pipe. See "Business -- Primary Markets and Products."

GROWTH STRATEGY
 
     The Company believes that the steel fabrication and erection industry will
continue to be characterized by large, complex, fast track projects. The
complexity and size of these projects requires companies with extended financial
and operational capabilities. With its integrated service capabilities and
financial and management strength, the Company intends to take advantage of this
trend. Additionally, the fragmented nature of the industry provides the Company
opportunities for growth. The Company seeks to achieve continued growth and
diminish the impact of business and economic cycles by pursuing a growth
strategy consisting of the following components:
 
          Promote Internal Growth.  The Company intends to pursue continued
     internal growth by adding sales and marketing personnel to dedicated, fast
     growing markets in which the Company is actively pursuing new projects, by
     further developing its engineering and design capabilities and fabrication
     capacity, and by continually updating its fabrication and detailing
     equipment and technologies. The Company believes that these efforts will
     enhance its market share, revenues, and operating income in its existing
     and targeted principal markets and improve its operating capacity.
     Recently, the Company dedicated one sales manager to the rapidly expanding
     Nevada commercial and industrial market and appointed one full-time
     marketing representative to pursue new project opportunities in South
     America. In addition, the Company recently secured additional office and
     administrative facilities, which will permit the expansion of its existing
     detailing, estimating, and other project operations. The Company also
     intends to invest approximately $2.5 million in new fabrication equipment
     and technologies in 1997.
 
          Acquire Synergistic Businesses.  The Company will pursue selective
     acquisitions of steel fabrication and erection companies that offer the
     Company increased plant facilities, opportunities to increase market share
     in selected geographic markets, penetration of new product market segments,
     and access to domestic and international markets targeted by the Company
     for geographic expansion. Such acquisitions may also provide the additional
     benefits of increased purchasing efficiencies with respect to steel and
     other raw materials, payment and performance bonding and insurance
     premiums, and more efficient allocation and utilization of labor resources
     among projects within its geographic markets. The Company believes that
     many of its competitors operate primarily on a local or limited geographic
     basis and, while having established relationships in those markets, lack
     the resources to compete for large or more complex projects. In addition,
     the industry is highly fragmented with many of the Company's competitors
     being closely or family held entities.
 
          In January 1997, the Company completed the acquisition of all of the
     outstanding capital stock of B&K Steel, a competitor of the Company located
     in the Phoenix metropolitan area. B&K Steel is primarily a fabrication
     contractor and had operating revenue of approximately $9.4 million in 1996.
     The Company believes that the acquisition of B&K Steel will enable the
     Company to capture a larger share of the Arizona industrial and commercial
     market and will provide the Company with increased access to the mining
     industry throughout the southwestern United States. The acquisition of B&K
     Steel also provides the Company with additional fabrication facilities
     located near the Company's existing facilities.
 
          Create Additional Project Opportunities.  The Company believes that
     its ability to efficiently coordinate and implement numerous design and
     logistical changes on large or more complex fast track projects, combined
     with its established long term relationships with key national and
     multi-national general contractors and other customers, will provide the
     Company with opportunities to market its services in a number of markets in
     which the Company has not yet achieved a leading position or conducted
     significant operations. Domestically, the Company plans to expand into
     markets in which it believes it can leverage its existing expertise to
     achieve a significant share of such markets. Among the regions targeted by
     the Company for domestic expansion are the Pacific Northwest, which
     presents several opportunities in the expanding computer chip manufacturing
     industry, and Texas, which offers the Company convenient and cost effective
     access to its developing international markets.
 
          The Company also will seek to capture significant market share in
     selected product markets. Among other markets, the Company is seeking to
     increase its participation in the construction of sports stadiums and
     airports and, through its acquisition of B&K Steel, the mining and smaller
     commercial construction
 
                                       29

     markets. The Company plans to participate in these markets through the
     acquisition of existing participants, expansion of strategic customer
     relationships into new markets, and through increased sales and marketing
     efforts generally.
 
          Expand Internationally and Develop Strategic Alliances.  The Company
     recently has developed its presence in selected international markets,
     including Chile and Argentina, and is pursuing opportunities in Mexico and
     Southeast Asia. Each of these international markets is expected to have a
     growing demand for services offered by the Company. In Argentina, the
     Company recently completed fabrication and erection coordination services
     for mill facilities at one of the largest copper mines in the world. The
     Company also completed a large mining project in Chile. In addition, the
     Company will seek to expand internationally by partnering with existing
     multi-national customers such as Fluor Daniel, Inc. and Bechtel Group,
     Inc., as well as other international structural and design engineering
     firms, and by entering into strategic alliances with leading foreign
     fabricators and erectors in the Company's targeted international markets.
     The Company believes that its international alliances also will help to
     reduce its risk of entry into foreign markets by partnering with entities
     having an established presence and experience in such markets.
 
          The Company has developed a strategic alliance with Corey, S.A. de
     C.V., Mexico's leading steel fabrication and erection contractor. Pursuant
     to this alliance, the parties intend to form a corporate joint venture that
     intends to provide detailing services to the Company's domestic operations.
     The Mexico joint venture intends to use state of the art Stru-Cad and
     Autocad design systems, and is expected to significantly expand the
     Company's internal detailing capacity. The Company believes its investment
     in this joint venture will reduce its reliance on detailing subcontractors
     and improve the Company's cost profile. The Company expects the alliance to
     provide it access to several large projects in Mexico through Corey's
     marketing, importation, and fabrication support.
 
PRIMARY MARKETS AND PRODUCTS
 
     The Company's current principal geographic markets include Arizona and

     Liberty, the Brooklyn Bridge, and other New York City landmarks.
 
          - LUXOR HOTEL AND CASINO SHOWROOM THEATER.  The Company has been
     involved in the construction of the Luxor Hotel and Casino Showroom Theater
     and renovation of the hotel ballroom.
 
     California Market.  The Company has maintained a strong presence in the
California market and intends to achieve a greater share of this geographic
market as it experiences an increase in new construction activity. The Company
provided fabrication and erection services for several new hospital facilities
in California, including the new Children's Hospital and Health Center in San
Diego, the expansion of the Sharp Women's Center in San Diego, which required
construction around existing and operating hospital wings, and the Valley
Medical Center in San Jose. The Company also was selected as the fabricator and
erector for the Fashion Valley Mall in San Diego, which involved the fabrication
and erection of over 7,000 tons of steel for a new second level of retail
shopping space, which was erected at night over the existing shopping facility
without disturbing the ordinary operations of the mall.
 
     Specialty Markets.  In addition to seeking to achieve a leading market
share in the principal geographic markets that it serves, the Company focuses
its fabrication and erection expertise on distinct product segments,
particularly product segments requiring unique or specialized expertise where
the Company has the potential to achieve a dominant market share. A recent
example of such a product segment is large diameter water pipe used in
governmental aqueduct systems. These projects require the complex formation and
welding of steel plate into large diameter pipe sections that are used to
transport water from major supply sources to various population centers,
primarily in the arid southwestern United States. The Company has developed
in-house specialized fabrication equipment used to construct and weld these pipe
sections, a unique coal tar and fiberglass enamel application system used to
coat the pipe, and customized transportation equipment
 
                                       31
<PAGE>   33
 
necessary to deliver the system to its ultimate destination. The Company's
expertise and specialized equipment development has made it a dominant
fabricator and erector of these large aqueduct projects in Arizona, Nevada, and
California. The Company's recently completed large diameter pipe projects
include the following:
 
          - SALT RIVER SIPHON REPLACEMENT PROJECT.  The Company served as the
     fabricator and erector for the Salt River Siphon Replacement project, a
     project requiring the fabrication of over 8,500 feet of 21 foot diameter
     pipe for the U. S. Bureau of Reclamation. The system will transport water
     from the Salt River near Phoenix, Arizona to the major population centers
     of Arizona.
 
          - AGUA FRIA SIPHON PROJECT.  This project was similar in scope to and
     followed the Company's successful completion of the Salt River Siphon
     project, and entailed the specialized fabrication and erection of over two
     miles of 21 foot diameter pipe from the Central Arizona Project canal
     system under the Agua Fria River to Phoenix, Arizona.
 
          - MOHAVE UNDERGROUND AQUEDUCT.  The Company was the contractor for the

BUSINESS OPERATIONS
 
     The primary services provided by the Company are engineering and
preparation of detail drawings, shop fabrication, and field erection. Following
is a description of the Company's principal services.
 
          - Engineering and Detailing.  The Company maintains significant
     in-house structural engineering and detailing capabilities which enable it
     to implement and coordinate with its shop and field personnel changes to
     building and structural designs sought by project owners or general
     contractors, and to help influence critical determinations as to the most
     cost effective systems, designs, connections, and erection procedures for a
     particular project. The Company's detailers prepare detail shop drawings of
     the dimensions, positions, locations, and connections, and the fabrication
     and erection sequences of, each piece of steel utilized in a project, and
     continually update these drawings to accommodate design and other changes.
     The Company utilizes a Stru-CAD automated detailing system that interacts
     electronically with the Company's numerically controlled fabrication
     equipment and produces updated detail drawings electronically, which are
     delivered to each of the Company's domestic and foreign field locations.
     The Company's detailing division initially prepares advance materials bills
     by size and length of each steel piece within pre-defined areas or
     sequences of erection for each project. Detailers coordinate directly with
     customers and the Company's fabrication and erection teams to determine and
     plan the order of fabrication and erection of a project and associated
     personnel and equipment requirements.
 
          - Shop Fabrication.  The Company's fabrication services consist of the
     procurement from steel producers of raw steel shapes in different sizes and
     lengths. These shapes vary in cross-section from I-beams to angle, channel,
     tube, pipe, and plate. Upon delivery of these steel shapes, and prior to
     fabrication, the Company prepares load lists that identify the sequence and
     date that each individual piece of steel is required on a project, a
     procedure that reduces the handling of and the need to store materials in
     the field. Upon completion of detailed shop drawings, the Company's
     fabrication shop cuts the raw steel pieces to length, drills and punches
     holes through the use of numerically controlled beam lines, and completes
     coping and beveling with its numerically controlled machinery and automated
     burning equipment. The Company then fabricates fittings and completes
     welding and inspection of each finished structural piece. The Company
     utilizes advanced technologies to inspect weld seams, which significantly
     reduces costs, fabrication hours, and the likelihood of structural defects.
     After the completion of processing to customer specifications, finished
     pieces are loaded for shipment to the construction site, often pursuant to
     just-in-time delivery schedules.
 
          - Field Erection.  The erection process typically consists of
     pre-assembly of steel component parts at the project site, the lifting of
     components by crane to the appropriate location at the site and the final
     assembly of major components to form the steel backbone of the project. The
     Company's field erection crews erect fabricated steel components in
     accordance with erection drawings prepared and updated by the Company's
     detailers. The erection process for each project is managed by experienced
     field supervisors and the Company employs local union erection personnel on
     an as needed basis in areas near the project sites.
 
PROJECT MANAGEMENT
 
     All contract awards to the Company are assigned a project number which is
used to track each steel component and man-hour associated with the project
through the entire construction process. All project drawings, specifications,
and completion schedules on a project are reviewed by the Company's General
Manager and all projects are assigned one or more Project Managers who assume
primary responsibility for all aspects of the project, subject to oversight by
the General Manager. Often a Project Manager assigned to a given project will
have significant experience in similar projects. A Project Manager generally
will be responsible for one to five projects in various stages of completion at
any given time, depending on the scope, complexity, and geographic location of
such projects. Each project is divided into critical sequences of steel groups
that follow the anticipated erection or fabrication path. Each sequence follows
a timeline and the status is continually monitored. The General Manager and
Project Manager for each project coordinate and manage design changes or other
changes in scheduled completion deadlines in an effort to minimize overall
project
 
                                       34
<PAGE>   36
 
delays. The Company provides production bonuses to its Project Managers based
on, among other factors, the achievement of lower costs on a project than the
estimated costs used to formulate the initial bid or price or prices of
subsequent change orders, and the ability to minimize costs or cost overruns on
particularly complex projects or on projects that exceed initial cost estimates.
 
     The Company believes that a key factor in its success has been its ability
to provide through its in-house personnel valuable input and assistance to
general contractors, engineering firms, and other customers with respect to
overall project design of fabrication and erection sequences and other critical
project decisions, which often results in overall project cost savings and
efficiencies and helps to solidify key customer relationships. In addition to
its centralized project management, the Company also uses a high percentage of
skilled erection employees local to projects and utilizes advanced scheduling
systems to enhance its ability to provide project management services to
customers complementary to its core engineering, detail drawing, shop
fabrication, and field erection services.
 
SAFETY AND QUALITY ASSURANCE
 
     The Company has adopted and maintains important safety policies that are
administered and enforced by the Company's top management. The Company considers
workplace accident prevention to be of primary importance in all phases of its
operations and provides continual training on safety procedures and techniques
to all of its shop and field personnel.
 
     The Company uses advanced welding and fabrication technologies and all of
the Company's products are fabricated in accordance with applicable industry and
specific customer standards and specifications. The Company has achieved and
maintains a level three certification by the American Institute of Steel
Construction (AISC) with respect to its fabrication operations, the highest
level of certification available from AISC. In addition, the Company's welding
employees are certified in accordance with the American Society of Mechanical
Engineers (ASME) Section IX, Non-Destructive Examination Inspector Certification
to Society Non-Destructive Testing TC-IA Standards. The Company has developed
project-specific and Company-wide quality assurance and quality control
programs, and utilizes sophisticated x-ray and ultra-sonic systems to inspect
weld seams.
 
SALES AND ESTIMATING
 
     The Company's domestic sales and marketing efforts are led by five sales
managers. Each sales manager is responsible primarily for the Company's sales
and marketing efforts in defined geographic areas. The Company also employs one
full-time international marketing representative responsible primarily for the
development of the emerging South American and Mexican markets. In addition, the
Company employs ten full-time project estimators and one chief estimator. The
Company's sales representatives maintain relationships with and make personal
and other sales calls on general contractors, architects, engineers, and other
potential sources of business to determine potential new projects under
consideration, which provide the Company with valuable market information and
new project opportunities. The Company maintains future projects reports in
order to track the weekly progress of new opportunities. The Company's sales
efforts are further supported by most of its executive officers and by its
engineering personnel, who have substantial experience in the design,
fabrication, and erection of structural steel and heavy steel plate.
 
     The Company competes for new project opportunities through its relationship
and interaction with its active and prospective customer base, which provides
the Company with valuable current market information and sales opportunities. In
addition, the Company frequently is contacted by governmental agencies in
connection with public construction projects, and by large private sector
project owners and by general contractors and engineering firms in connection
with new building projects such as plants, warehouse and distribution centers,
and other industrial and commercial facilities.
 
     Upon selection of projects to bid or price, the Company's estimating
division reviews and prepares projected costs of shop, field, detail drawing
preparation and crane hours, steel and other raw materials, and
 
                                       35
<PAGE>   37
 
other costs. On bid projects, a formal bid is prepared detailing the specific
services and materials to be provided by the Company, payment terms and project
completion timelines. Upon acceptance, the Company's bid proposal is finalized
in a definitive contract.
 
CONTRACTING METHODS AND PERFORMANCE BONDING
 
     The Company's projects are awarded through a competitive bid process or are
obtained through negotiation, in either case generally using one of two types of
contract pricing approaches: fixed price or cost-plus pricing. Under the fixed
price approach, the Company receives the price fixed in the contract, subject to
adjustment only for change orders placed by the customer. As a result, the
Company retains all cost savings but is also responsible for cost overruns.
Under the cost-plus arrangement, the Company receives a specified fee in excess
of its direct labor and material cost, up to a maximum amount, and thus seeks to
gain protection against cost overruns and sometimes benefits directly from cost
savings. Historically, a substantial majority of the Company's contracts have
been fixed price arrangements.
 
     While customers may consider a number of factors, including availability,
capability, reputation, and safety record, price and the ability to meet
customer imposed project schedules are the principal factors on which the
Company obtains contracts. Generally, the Company's contracts and projects vary
in length from three to twelve months depending on the size and complexity of
the project, project owner demands, and other factors.
 
     The Company's contract arrangements with customers sometimes require the
Company to provide payment and performance bonds and, in selected cases
typically associated with international projects, letters of credit, to
partially secure the Company's obligations under its contracts. Bonding
requirements typically arise in connection with public works projects and
sometimes with respect to certain private contracts. The Company's payment and
performance bonds are obtained through surety companies and typically cover the
entire contract price on a project. The Company believes that its bonding
capacity provides a competitive advantage in some cases due to the Company's
ability to obtain large bonds and to negotiate more favorable pricing of bonds.
 
BACKLOG
 
     The Company considers backlog an important indicator of its operating
condition because its engineering, detailing, fabrication, and erection services
are characterized by long lead times for projects and orders. The Company
defines its backlog of contract commitments as the potential future revenues to
be recognized upon performance of contracts awarded to the Company. Backlog
increases as new contract commitments are obtained, decreases as work is
performed and the related revenues are recognized, and increases or decreases as
modifications in work are performed under a contract. As of December 31, 1996,
the Company's backlog was $67.3 million. As of March 31, 1996 and 1997, the
Company's backlog was $126.1 million and $65.6 million, respectively. Of the
Company's $67.3 million backlog as of December 31, 1996, approximately $13.1
million was attributable to three projects for a single customer in Las Vegas,
Nevada, and approximately $34.3 million was attributable to the Bank One
Ballpark project in Phoenix, Arizona. Of the Company's $65.6 million backlog as
of March 31, 1997, approximately $15.9 million was attributable to two projects
for a single customer in Las Vegas, and approximately $26.8 million was
attributable to the Bank One Ballpark project. The Company expects approximately
97% of its backlog as of December 31, 1996, and approximately 97% of its backlog
as of March 31, 1997, to be recognized as revenues in 1997.
 
COMPETITION
 
     The principal geographic and product markets served by the Company are
highly competitive. The Company competes with other contractors on a local,
regional, or national basis, and, in certain cases, on an international basis.
The Company has different competitors for each of its services and product
segments and within each geographic market served by the Company. The Company
believes that it can compete effectively for new projects both nationally and
internationally and that it is among the largest competitors in its industry.
Among the principal competitive factors within the industry are price,
timeliness of completion of projects,
 
                                       36
<PAGE>   38
 
quality, reputation, and the desire of customers to utilize specific contractors
with whom they have favorable relationships and prior experience. Certain of the
Company's competitors have financial and operating resources greater than those
of the Company.
 
GOVERNMENTAL REGULATION
 
     The Company's operations are governed by and subject to government
regulations in the United States and in foreign countries in which the Company
operates, including laws and regulations relating to workplace safety and worker
health, principally the Occupational Safety and Health Act and regulations
thereunder in the United States. With respect to its international operations,
the Company is subject to a number of laws and regulations, including those
relating to taxation of its earnings and earnings of its personnel and its use
of local personnel and suppliers. The Company's operations are subject to the
risk of changes in federal, state, and local laws and policies which may impose
restrictions on the Company, including trade restrictions, expropriation or
nationalization decrees, confiscatory tax systems, primary or secondary boycotts
or embargos directed at specific countries, import restrictions or other trade
barriers, and mandatory sourcing rules, any of which could, if adopted or
implemented, materially and adversely affect the Company. The Company believes
that it is in material compliance with the laws and regulations under which it
and its operations are currently governed and does not believe that future
compliance with such laws and regulations will have a material and adverse
effect on it. The Company cannot determine, however, to what extent future
operations and earnings of the Company may be affected by new legislation, new
regulations, or changes in or new interpretations of existing regulations.
 
     The Company is subject to licensure and holds licenses in each of the
states in the United States in which it operates and in certain local
jurisdictions within such states. The Company believes that it is in material
compliance with all contractor licensing requirements in the various states in
which it operates. The loss or revocation of any license or the limitation on
any of the Company's primary services thereunder in any state in which the
Company conducts substantial operations could prevent the Company from
conducting further operations in such jurisdiction and would have a material
adverse effect on the Company.
 
ENVIRONMENTAL REGULATION
 
     The Company's operations and properties are affected by numerous federal,
state, and local environmental protection laws and regulations, such as those
governing discharges into air and water, and the handling and disposal of solid
and hazardous waste. The requirements of these laws and regulations have become
increasingly stringent, complex, and costly to comply with. In addition, the
Company may be subject to claims alleging personal injury or property damage as
a result of alleged exposure to hazardous substances. The Company is not aware
of any non-compliance with environmental laws that could have a material adverse
effect on the Company's business or operations. There can be no assurance,
however, that such laws, regulations, or their interpretation will not change in
the future in a manner that could materially and adversely affect the Company.
 
     Certain environmental laws, such as CERCLA, provide for strict and joint
and several liability for investigation and/or remediation of spills and other
releases of hazardous substances. Such laws may apply to conditions at
properties presently owned or operated by the Company or its predecessors, as
well as to conditions at properties at which waste or other contamination
attributable to an entity or its predecessors come to be located. The Company's
facilities have been operated for many years, and substances that are or might
be considered hazardous were used at such locations. The Company does not
anticipate incurring material capital expenditures for environmental controls or
for investigation or remediation of environmental conditions during the current
or succeeding fiscal year. Nevertheless, the Company can give no assurance that
it, or entities for which it may be responsible, will not incur liability in
connection with the investigation and remediation of facilities it currently
owns or operates or other locations in a manner that could materially and
adversely affect the Company.

EMPLOYEES
 
     As of March 31, 1997, the Company employed approximately 765 people. The
number of persons employed by the Company on an hourly basis fluctuates directly
in relation to the amount of business performed by the Company. Certain of the
fabrication and erection personnel employed by the Company are represented by
the United Steelworkers of America, the International Association of Bridge,
Structural and Ornamental Iron Workers Union, the International Union of
Operating Engineers, and the International Brotherhood of Boilermakers, Iron
Shipbuilders, Blacksmiths, Forgers and Helpers Union. The Company is a party to
several separate collective bargaining agreements with such unions in certain of
the Company's current operating regions, which expire (if not renewed) at
various times in the future. Most of the Company's collective bargaining
agreements are subject to automatic annual or other renewal unless either party
elects to terminate the agreement on the scheduled expiration date. The Company
considers its relationship with its employees to be good and, other than
sporadic and unauthorized work stoppages of an immaterial nature, none of which
have been related to the Company's own labor relations, the Company has not
experienced a work stoppage or other labor disturbance. See "Risk
Factors -- Union Contracts."
 
     The Company utilizes third-party fabrication subcontractors on many of its
projects and also subcontracts detailing services from time to time when it
lacks available in-house capacity for such services. The Company's inability to
engage fabrication and detailing subcontractors on terms favorable to the
Company could limit the Company's ability to complete projects in a timely
manner or compete for new projects and could have a material adverse effect on
the Company. See "Risk Factors -- Dependence on Subcontractors."
 
PROPERTIES
 
     The Company's primary fabrication facilities consist of over 400,000 square
feet of shop space under roof on approximately 26 acres in Phoenix, Arizona.
These facilities also house the Company's executive and administrative offices
and engineering and detailing division and are leased by the Company from a
partnership owned by certain affiliates of the Company. This lease was recently
amended as of March 1, 1997 and expires on February 28, 2017. Annual rent under
the lease totaled $252,000 and $264,000 for 1995 and 1996, respectively, and
will be $292,000 in 1997, $414,000 in 1998, $556,000 in 1999, $601,000 in 2000,
and $605,000 in each year thereafter during the remaining term of the lease,
subject to increase every five years commencing in 2002 pursuant to a Consumer
Price Index formula. See "Certain Relationships and Related Transactions."
 
     With the acquisition of B&K Steel, the Company added approximately 145,000
square feet of covered fabrication, office, engineering and detailing facilities
on approximately 23 acres in Gilbert, Arizona. The property on which B&K Steel's
facilities are located was acquired by a partnership owned by certain affiliates
of the Company and is leased to the Company by that partnership. This lease
commenced on March 1, 1997 and expires on February 28, 2017. Annual rent under
the lease is estimated to be $283,000 in 1997 and $340,000 in each year
thereafter, subject to increase every five years commencing in 2002 based on a
Consumer Price Index formula. See "Certain Relationships and Related
Transactions."
 
     A partnership owned by certain affiliates of the Company has acquired and
is leasing to the Company additional facilities consisting of approximately
22,000 square feet of office space adjacent to its existing principal
fabrication and office facilities. This lease commenced on May 1, 1997 and
expires April 30, 2017. Annual rent under the lease will be $90,000 in 1997 and
$135,000 in each year thereafter, subject to increase every five years based on
a Consumer Price Index formula. The Company anticipates that a portion of the
premises will be subleased. See "Certain Relationships and Related
Transactions."
 
     Under each of the foregoing leases, the Company also is obligated to pay
all taxes, insurance and maintenance costs.

SUPPLIERS
 
     The Company currently purchases a majority of its steel and steel
components from several domestic and foreign steel producers and suppliers.
However, steel is readily available from numerous foreign and domestic steel
producers. The Company is not dependent on any one supplier. The Company
believes that its relationships with its suppliers are good and has no long term
commitments with any of its suppliers.
 
LEGAL PROCEEDINGS AND INSURANCE
 
     Construction in general and the fabrication and erection of structural
steel and heavy steel plate in particular involve a high degree of operational
risk. Adverse weather conditions, operator and other error, and other unforeseen
factors can cause personal injury or loss of life, severe damage to or
destruction of property and equipment, and suspension of operations. Litigation
arising from such occurrences may result in the Company being named as a party
to lawsuits asserting substantial claims or to administrative or criminal
actions that may involve substantial monetary penalties or the restriction of
the Company's operations in one or more jurisdictions.
 
     The Company is a defendant in lawsuits from time to time, including
lawsuits arising in the normal course of its business. While it is impossible at
this time to determine with certainty the ultimate outcome of these lawsuits,
the Company's management believes that adequate provisions have been made for
probable losses as best as can be determined at this time and that the ultimate
outcome, after provisions therefor, will not have a material adverse effect on
the Company.
 
     The Company maintains workers compensation insurance that provides full
coverage of statutory workers compensation benefits. The Company also maintains
employer liability insurance in its principal geographic markets in amounts of
$1,000,000 per accident for bodily injury by accident and $1,000,000 per
employee (and as a policy limit) for bodily injury by disease and contractors
commercial general liability insurance in the amount of $1,000,000. In addition,
the Company maintains umbrella coverage limits of $14,000,000. The Company also
maintains insurance against property damage caused by fire, flood, explosion and
similar catastrophic events that may result in physical damage or destruction of
the Company's facilities and property. All policies are subject to various
deductibles and coverage limitations. Although management of the Company
believes that the Company's insurance is adequate for its present needs, there
can be no assurance that the Company will be able to maintain adequate insurance
at premium rates that management considers commercially reasonable, nor can
there be any assurance that such coverage will be adequate to cover all claims
that may arise.
 
     The adequacy of reserves applicable to the potential costs of being engaged
in litigation and potential liabilities resulting from litigation are reviewed
as developments in the litigation warrant. The Company seeks to mitigate the
effects of loss or damage through the maintenance of risk management, insurance,
and safety programs. There can be no assurance, however, that the Company's
efforts to mitigate losses will be successful or that any losses incurred will
not exceed the Company's insurance or estimated reserves therefor. See "Risk
Factors -- Operating Risks."

    Compensation Plan."
 
1997 STOCK OPTION PLAN
 
     In February 1997, the Company's Board of Directors and stockholders
approved the Schuff Steel Company 1997 Stock Option Plan (the "Option Plan").
Under the Option Plan, the Company may grant incentive stock options or
non-qualified stock options to directors, employees, consultants, and advisors
of the Company. The Company believes that the Option Plan promotes the success
and enhances the value of the Company by linking the personal interests of
participants to those of the Company's stockholders and providing participants
with an incentive for outstanding performance. The total number of shares of
Common Stock available for awards under the Option Plan is 600,000, subject to a
proportionate increase or decrease in the event of a stock split, reverse stock
split, stock dividend, or other adjustment to the Company's total number of
issued and outstanding shares of Common Stock.
 
     Following this offering, the Option Plan will be administered by the Board
of Directors or a committee that is appointed by, and serves at the discretion
of, the Board of Directors consisting solely of non-employee directors. The
Board of Directors or the committee, as the case may be, will have the exclusive
authority to administer the Option Plan, including the power to determine
eligibility, the type and number of awards to be granted, and the terms and
conditions of any award granted, including the price and timing of awards. As of
the date of this Prospectus, the Company has granted options to purchase 345,500
shares of Common Stock to various of its employees. Generally, such options are
subject to vesting over a five-year period, with 20% of the options becoming
exercisable by the holder thereof on each successive anniversary date of the
grant. The exercise price of the options granted to date is $5.00 per share.

401(k) PLAN
 
     Under the Company's 401(k) retirement savings plan, eligible employees may
direct that a portion of their compensation, up to a maximum of $9,500 per year,
be withheld by the Company and contributed to their account. All 401(k) plan
contributions are placed in a trust fund to be invested by the 401(k) plan's
trustee, except that the 401(k) plan may permit participants to direct the
investment of their account balances among mutual or investment funds available
under the plan. The 401(k) plan permits the Company to provide discretionary
matching contributions not to exceed 25% of the amount deferred up to 5% of a
participant's compensation. Amounts contributed to participant accounts under
the 401(k) plan and any earnings or interest accrued on the participant accounts
are generally not subject to federal income tax until distributed to the
participant and may not be withdrawn until death, retirement, or termination of
employment.
 
DEFERRED COMPENSATION PLAN
 
     In 1996, the Company maintained a Supplemental Retirement and Deferred
Compensation Plan, pursuant to which it contributed on a discretionary basis to
certain key employees 10% of annual net profits, which amount was allocated
among participants in accordance with individual agreements between the Company
and such participants. In 1996, the Company recorded expenses of $528,900 in
accordance with this Plan. This Plan was terminated in 1997 and the Company is
considering alternative bonus arrangements for certain key employees.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     For the year ended December 31, 1996, the Company's Board of Directors
established levels of compensation for certain of the Company's executive
officers without the involvement of the Compensation Committee, which had not
yet been formed. David A. Schuff and Scott A. Schuff, the Company's Chairman and
President/Chief Executive Officer, respectively, participated in the
deliberations regarding executive compensation that occurred during 1996. The
Board of Directors will select members of the Compensation Committee following
the closing of this offering, each of which will be a non-employee member of the
Company's Board of Directors.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Since its inception, the Company has maintained business relationships and
engaged in certain transactions with the affiliated companies and parties
described below. In the future, any transactions between the Company and its
affiliated entities, executive officers, directors, or significant stockholders
will require the approval of a majority of the non-employee directors of the
Company and will be on terms that will be no less favorable to the Company than
the Company could obtain from non-affiliated parties.
 
     The Company and B&K Steel lease their respective fabrication and office
facilities from 19th Avenue/ Buchanan Limited Partnership, an Arizona limited
partnership (the "Schuff Partnership"). The general and limited partners of the
Schuff Partnership are David A. Schuff, Scott A. Schuff, and certain of their
family members. David A. Schuff is a co-founder and the Chairman of the Board of
Directors of the Company, and Scott A. Schuff is a Director and the President
and Chief Executive Officer of the Company. David A. Schuff and Scott A. Schuff
presently are the beneficial owners of 100% of the outstanding Common Stock of
the Company and it is estimated that after this offering they will own
beneficially approximately 69.4% of the issued and outstanding Common Stock of
the Company (or approximately 66.4% if the Underwriters' over-allotment option
is exercised). See "Management" and "Principal Stockholders."
 
     In March 1997, the Company entered into a new lease agreement with the
Schuff Partnership with respect to its primary fabrication facilities. These
facilities include approximately 400,000 square feet of shop space under roof
situated on approximately 26 acres. This new lease agreement was based upon a
third party appraisal of the property and an assumed annual rate of return of
10%, which took into account the location and use of the property, potential
tenants, comparable returns on similar properties, and other relevant factors.
The new lease increased the Company's annual rent payments from $264,000 in 1996
to $292,000 for 1997, $414,000 for 1998, $556,000 for 1999, $601,000 for 2000,
and $605,000 for each year thereafter, subject to increase in 2002 and every
five years thereafter based on a Consumer Price Index formula, which represents
an annual rent per square foot of improved space of $0.66, $0.73, $1.04, $1.39,
$1.50 and $1.51, respectively. The agreement also enabled the Company to extend
the lease term to 20 years. The Company also is obligated under the lease to
reimburse the Schuff Partnership an additional amount equal to any taxes
incurred by it in connection with the lease payments, and is obligated to pay
insurance and maintenance expenses. The term of this lease expires on February
28, 2017.
 
     In March 1997, the Company also entered into a lease agreement with the
Schuff Partnership with respect to the recently acquired B&K Steel property,
consisting of approximately 145,000 square feet of covered fabrication, office,
engineering and detailing facilities on approximately 23 acres. Based upon the
same methodology described above, the Company entered into a lease with
substantially similar terms for the property and equipment with annual rent
payments of approximately $340,000 over 20 years, subject to increase every five
years based on a Consumer Price Index formula, representing an annual rent per
square foot of improved space of approximately $2.34. The rent was based upon a
recent appraisal of the underlying property. The Company also is obligated to
reimburse the Schuff Partnership for taxes incurred by it in connection with the
lease payments. The term of the lease expires on February 28, 2017.
 
     Effective May 1, 1997, the Schuff Partnership leased to the Company
approximately 22,000 square feet of additional office facilities adjacent to the
Company's existing principal office and shop facilities. Based upon the same
methodology described above, the Company entered into a lease with substantially
similar terms for the property with annual rent payments of $135,000 over 20
years, subject to increase every five years based on a Consumer Price Index
formula, representing an annual rent per square foot of improved space of
approximately $6.14. The rent was based upon the purchase price of the property,
which was determined by arm's-length negotiation with the seller. The Company is
also obligated to reimburse the Schuff Partnership for taxes incurred by it in
connection with the lease and is obligated to pay insurance and maintenance
costs. This lease expires on April 30, 2017. See "Business -- Properties."
 
     In 1989, the Schuff Partnership borrowed $5,000,000 from a commercial bank
in connection with its refinancing of the property on which the Company's
principal facilities are located (the "Partnership Loan"). The Schuff
Partnership in turn loaned $4,249,062 to the Company and the Company delivered
to the Schuff Partnership a subordinated promissory note in that amount (the
"Subordinated Loan"). As of March 31,
 
                                       45
<PAGE>   47
 
1997, the principal balance of the Subordinated Loan was $2,265,016. In April
1996, in connection with the refinancing of the Partnership Loan, the Company
guaranteed repayment of the Schuff Partnership's indebtedness under that loan,
which guarantee is anticipated to be released following the closing of this
offering.
 
     Mr. David A. Schuff, Mrs. Nancy A. Schuff, his wife, and Mr. Scott A.
Schuff have personally guaranteed the Company's indebtedness under its revolving
credit and equipment purchase facilities.
 
     The Company historically has made cash advances to its principal
stockholders. Such advances have been evidenced by recourse promissory notes
that are payable on demand after one year. As of March 31, 1997, there were no
amounts owed by David A. Schuff and Scott A. Schuff under such notes. The
Company does not intend to continue the practice of advancing funds to its
stockholders after this offering.
 
     The Company currently purchases a portion of its steel inventory from
Arizona Steel, Inc., an Arizona corporation ("Arizona Steel"), in which Scott A.
Schuff owns a 75% interest. Arizona Steel is a steel distribution center formed
in January 1997 that sells steel pieces to a number of fabrication contractors,
one of approximately twenty from which the Company purchases steel from time to
time. The Company purchases most of its steel inventory directly from various
steel mills but from time to time purchases small quantities of steel from local
steel distribution centers as a result of special needs that do not permit the
lead time or volumes normally associated with mill purchases. The Company
currently includes Arizona Steel among its list of suppliers, all of which bid
for purchase orders by the Company on the basis of cost, availability and
delivery. It is the Company's policy not to make purchases from Arizona Steel
unless it offers the most competitive terms based on the factors listed above.
In the first four months of 1997, the Company purchased approximately $47,000 of
steel from Arizona Steel, representing less than 0.5% of the steel purchased
from all suppliers during that period.

                          DESCRIPTION OF CAPITAL STOCK
 
     The following description of the Company's capital stock does not purport
to be complete and is subject in all respects to applicable Delaware law and to
the provisions of the Company's Certificate of Incorporation and Bylaws, copies
of which have been filed as exhibits to the Registration Statement of which this
Prospectus is a part.
 
     The authorized capital stock of the Company consists of 20,000,000 shares
of Common Stock, par value $.001 per share, and 1,000,000 shares of Preferred
Stock, par value $.001 per share. Immediately following the completion of this
offering, 7,200,000 shares of Common Stock will be issued and outstanding and no
shares of Preferred Stock will be issued and outstanding.
 
COMMON STOCK
 
     Holders of Common Stock are entitled to one vote for each share held of
record on all matters on which stockholders are entitled to vote. Holders of
Common Stock do not have cumulative voting rights, and therefore holders of a
majority of the shares voting for the election of directors can elect all of the
directors. Holders of Common Stock are entitled to receive such dividends as may
be declared from time to time by the Board of Directors out of funds legally
available therefor. The Company does not anticipate declaring cash dividends in
the foreseeable future. See "Dividend Policy." In the event of liquidation,
dissolution, or winding up of the Company, the holders of Common Stock are
entitled to share ratably in any corporate assets remaining after payment of all
debts, subject to any preferential rights of any outstanding Preferred Stock.
Holders of Common Stock have no preemptive, conversion, or redemption rights and
are not subject to further calls or assessments by the Company. All of the
outstanding shares of Common Stock are, and the shares offered by the Company
hereby will be, if issued, validly issued, fully paid, and nonassessable. As of
the date of this Prospectus, there are four record holders of Common Stock.
 
PREFERRED STOCK
 
     The Board of Directors of the Company has the authority, without further
action by the Company's stockholders, to issue from time to time up to 1,000,000
shares of Preferred Stock in one or more series and to fix the number of shares,
designations, voting powers, preferences, optional and other special rights, and
the restrictions or qualifications thereof. The rights, preferences, privileges,
and restrictions or qualifications of different series of Preferred Stock may
differ with respect to dividend rates, amounts payable on liquidation, voting
rights, conversion rights, redemption provisions, sinking fund provisions, and
other matters. The issuance of Preferred Stock could: (i) decrease the amount of
earnings and assets available for distribution to holders of Common Stock; (ii)
adversely affect the rights and powers, including voting rights, of holders of
Common Stock; and (iii) have the effect of delaying, deferring, or preventing a
change in control of the Company. The Company has no present plans to issue any
shares of Preferred Stock.
 
ANTI-TAKEOVER LAW
 
     The Company is subject to Section 203 of the General Corporation Law of the
State of Delaware ("Section 203"), which restricts certain transactions and
business combinations between a corporation and an "Interested Stockholder"
owning 15% or more of the corporation's outstanding voting stock for a period of
three years from the date the stockholder becomes an Interested Stockholder.
Subject to certain exceptions, unless the transaction is approved by the board
of directors or the holders of at least two-thirds of the outstanding voting
stock of the corporation (excluding shares held by the Interested Stockholder),
Section 203 prohibits significant business transactions such as a merger with,
disposition of assets to, or receipt of disproportionate financial benefits by
the Interested Stockholder, or any other transaction that would increase the
Interested Stockholder's proportionate ownership of any class or series of the
corporation's stock. The statutory ban does not apply if, upon consummation of
the transaction in which any person becomes an Interested Stockholder, the
Interested Stockholder owns at least 85% of the outstanding voting stock of the
corporation (excluding shares held by persons who are both directors and
officers or by certain employee stock plans).

LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Certificate of Incorporation provides that to the fullest
extent permitted by Delaware law, a director of the Company shall not be
personally liable to the Company or its stockholders for monetary damages for
breach of such director's fiduciary duty, except for liability: (i) for any
breach of the director's duty of loyalty to the Company or its stockholders;
(ii) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law; (iii) in respect of certain unlawful
dividend payments or stock redemptions or repurchases; and (iv) for any
transaction from which the director derives an improper benefit. The effect of
the provision of the Company's Certificate of Incorporation is to eliminate the
rights of the Company and its stockholders (through stockholders' derivative
suits on behalf of the Company) to recover monetary damages against a director
for breach of the fiduciary duty of care as a director (including breaches
resulting from negligent or grossly negligent behavior), except in the
situations described in clauses (i) through (iv) above. This provision does not
limit or eliminate the rights of the Company or any stockholder to seek
nonmonetary relief such as an injunction or rescission in the event of a breach
of a director's duty of care. In addition, the Company's Certificate of
Incorporation provides that the Company shall indemnify any person who is or was
a director, officer, employee, or agent of the Company, or who is or was serving
at the request of the Company as a director, officer, employee, or agent of
another corporation or entity, against expenses, liabilities, and losses
incurred by any such person by reason of the fact that such person is or was
acting in such capacity. The Company's Certificate of Incorporation also permits
it to secure insurance on behalf of any director, officer, employee, or agent of
the Company for any liability arising out of such person's actions in such
capacity.
 
     The Company contemplates entering into agreements to indemnify its
directors and officers. These agreements would, among other things, indemnify
the Company's directors and officers for certain expenses (including attorneys'
fees), judgments, fines, and settlement amounts incurred by any such person in
any action or proceeding, including any action by or in the right of the
Company, arising out of such person's services as a director or officer of the
Company, any subsidiary of the Company, or any other company or enterprise to
which such person provides services at the request of the Company. To the extent
that the Board of Directors or the stockholders of the Company may in the future
wish to limit or repeal the ability of the Company to provide indemnification as
set forth in the Company's Certificate of Incorporation, such repeal or
limitation may not be effective as to directors or officers who are parties to
the indemnification agreements because their rights to full protection would be
contractually assured by such agreements. It is anticipated that similar
contracts may be entered into, from time to time, with future directors of the
Company. The Company believes that the indemnification provisions in its
Certificate of Incorporation and in the indemnification agreements are necessary
to attract and retain qualified persons as directors and officers.
 
CERTAIN BYLAW PROVISIONS
 
     The Company's Bylaws contain several provisions that regulate the
nomination of directors and the submission of proposals in connection with
stockholder meetings. The Company's Bylaws require that any stockholder desiring
to propose business or nominate a person to the Board of Directors at an annual
stockholders meeting must give notice of any proposals not less than 90 days
prior to the anniversary date of the immediately preceding annual meeting,
subject to certain exceptions. Such notice is required to contain certain
information as set forth in the Bylaws. No business matter shall be transacted
nor shall any person be eligible for election as a director of the Company
unless proposed or nominated, as the case may be, in strict accordance with this
procedure set forth in the Company's Bylaws.
 
     Although the Bylaws do not give the Board of Directors any power to approve
or disapprove of stockholder nominations for the election of directors or of any
other business desired by stockholders to be conducted at an annual or any other
meeting, the Bylaws may have the effect of precluding a nomination for the
election of directors or the conduct of business at a particular annual meeting
if the proper procedures are not followed or may discourage or deter a third
party from conducting a solicitation of proxies to elect its own slate of
directors or otherwise attempting to obtain control of the Company, even if the
conduct of such solicitation or such attempt might be beneficial to the Company
and its stockholders. The Company's procedures with respect to all stockholder
proposals and the nomination of directors will be conducted in
 
                                       48
<PAGE>   50
 
accordance with Section 14 of the Securities Exchange Act of 1934, as amended,
and the rules promulgated thereunder.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock of the Company is
Harris Trust Company of California, 601 S. Figueroa, Los Angeles, California
95517.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have outstanding
7,200,000 shares of Common Stock. Of these shares, the 2,200,000 shares of
Common Stock sold in this offering, plus any additional shares sold upon
exercise of the Underwriters' over-allotment option, will be freely tradeable
without restriction under the Securities Act. Commencing 180 days following the
date of this Prospectus, 5,000,000 shares of Common Stock held by existing
stockholders will become eligible for sale under Rule 144, subject to compliance
with the volume limitations and other requirements of Rule 144.
 
     In general, under Rule 144 persons (or persons whose shares are aggregated)
who have beneficially owned "restricted" shares for at least one year, including
persons who are "affiliates" of the Company, as that term is defined under Rule
144, are entitled to sell (in accordance with the provisions specified in the
rule) within any three-month period a number of shares that does not exceed the
greater of one percent of the then outstanding shares of the Company's Common
Stock (72,000 shares immediately following this offering assuming no exercise of
the Underwriters' over-allotment option) or the average weekly trading volume of
the Common Stock during the four calendar weeks preceding the date on which
notice of the sale is filed with the Commission. All of the 5,000,000 shares
presently outstanding are "restricted" shares and have been beneficially owned
by persons who are "affiliates" of the Company for more than one year.
 
     The Company, its existing stockholders, directors, director-nominees and
officers have agreed with the Underwriters that, except in certain
circumstances, they will not issue, offer to sell, sell, contract to sell, or
otherwise dispose of any shares of Common Stock or any shares convertible or
exchangeable into any shares of Common Stock for a period of 180 days after the
date of this Prospectus without the prior written consent of the Representative.
 
     Prior to this offering, there has been no public market for the Company's
Common Stock and no prediction can be made of the effect, if any, that market
sales of shares or the availability of such shares for sale will have on the
market price prevailing from time to time. Nevertheless, sales of substantial
amounts of the Common Stock in the public market could adversely affect
prevailing market conditions and could impair the Company's future ability to
raise capital through the sale of its equity securities. See "Risk Factors --
Shares Eligible for Future Sale."

     The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to certain conditions precedent, including
the absence of any material adverse change in the Company's business and the
receipt of certain certificates, opinions, and letters from the Company and its
respective counsel and the Company's independent certified public accountants.
The nature of the Underwriters' obligation is such that they are committed to
purchase and pay for all the shares of Common Stock if any are purchased. In the
event of a failure by any Underwriter to purchase its portion of the Common
Stock, the Underwriting Agreement provides, depending upon the total number of
shares of Common Stock involved in the default, that the purchase commitments of
the other Underwriters may be increased or that the Underwriting Agreement may
be terminated, without prejudice to the right of any party as against any
defaulting Underwriter.
 
     The Company has been advised by the Representative that the Underwriters
propose to offer the shares of Common Stock directly to the public at the
initial public offering price set forth on the cover page of this Prospectus and
to certain securities dealers at such price less a concession not in excess of
$          per share. The Underwriters may allow, and such selected dealers may
reallow, a discount not in excess of $          per share to certain brokers and
dealers. After the initial public offering of the shares, the public offering
price and other selling terms may be changed by the Representative. No change in
such terms shall change the amount of proceeds to be received by the Company as
set forth on the cover page of this Prospectus.
 
     The Representative is permitted to engage in certain transactions that
stabilize the price of the Common Stock. Such transactions consist of bids or
purchases for the purpose of fixing or maintaining the price of the Common
Stock. If the Underwriters create a short position in the Common Stock in
connection with this offering, i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus, the Representative may
reduce that short position by purchasing Common Stock in the open market. The
Representative may also elect to reduce any short position by exercising all or
part of the over-allotment option described below. The Representative may also
impose a penalty bid on certain Underwriters. This means that if the
Representative purchases shares of Common Stock in the open market to reduce the
Underwriters' short position or to stabilize the price of the Common Stock, they
may reclaim the amount of the selling concession from the Underwriters who sold
those shares as part of this offering. In general, purchases of a security for
the purpose of stabilization or to reduce a short position could cause the price
of the security to be higher than it might be in the absence of such purchases.
The imposition of a penalty bid might also have an effect on the price of a
security to the extent that it discourages resales of the security. Neither the
Company nor any of the Underwriters makes any representation or prediction as to
the direction or magnitude of any effect that the transactions described above
may have on the price of the Common Stock. In addition, neither the Company nor
any of the Underwriters makes any representation that the Representative will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
 
                                       50

     The Company has granted an option to the Underwriters, exercisable for a
period of 30 days after the date of this Prospectus, to purchase up to an
additional 330,000 shares of Common Stock at the public offering price set forth
on the cover page of this Prospectus, less the underwriting discounts and
commissions. The Underwriters may exercise this option only to cover
over-allotments, if any. To the extent that the Underwriters exercise this
option, each of the Underwriters will be committed, subject to certain
conditions, to purchase such additional shares of Common Stock in approximately
the same proportion as set forth in the above table.
 
     Prior to this offering, there has been no established trading market for
the Common Stock. Consequently, the initial public offering price for the Common
Stock offered hereby has been determined by negotiation among the Company and
the Representative. Among the factors considered in such negotiations were the
preliminary demand for the Common Stock, the prevailing market and economic
conditions, the Company's results of operations, estimates of the business
potential and prospects of the Company, the present state of the Company's
business operations, an assessment of the Company's management, the
consideration of these factors in relation to the market valuation of comparable
companies in related businesses, the current condition of the markets in which
the Company operates, and other factors deemed relevant. There can be no
assurance that an active trading market will develop for the Common Stock or
that the Common Stock will trade in the public market subsequent to this
offering at or above the initial public offering price.
 
     The Underwriting Agreement provides that the Company will indemnify the
Underwriters and their controlling persons against certain liabilities under the
Securities Act or will contribute to payments the Underwriters and their
controlling persons may be required to make in respect thereof. The Company has
been advised that, in the opinion of the Commission, such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.
 
     The foregoing is a brief summary of certain provisions of the Underwriting
Agreement and does not purport to be a complete statement of its terms and
conditions. A copy of the Underwriting Agreement is on file with the Commission
as an exhibit to the Registration Statement of which this Prospectus forms a
part. See "Additional Information."

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Schuff Steel Company
 
     We have audited the accompanying balance sheets of Schuff Steel Company as
of December 31, 1996 and 1995, and the related statements of income, changes in
stockholders' equity, and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the 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 financial statements referred to above present fairly,
in all material respects, the financial position of Schuff Steel Company at
December 31, 1996 and 1995, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

     (THE INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
                                   UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Description of Business
 
     Schuff Steel Company ("the Company") is a steel fabrication and erection
contractor based in Phoenix, Arizona. The Company's construction projects are
located primarily in Arizona, Nevada, California and South America.
 
  Principles of Consolidation
 
     As more fully described in Note 13, the Company acquired B&K Steel
Fabrications, Inc. (B&K Steel) on January 31, 1997 and accounted for the
transaction using the purchase method. Effective as of that date, B&K Steel
became a wholly owned subsidiary of the Company. Accordingly, commencing with
the three month period ended March 31, 1997 the Company began consolidating the
financial statements of B&K Steel from the date of acquisition. All intercompany
transactions have been eliminated for the three months ended March 31, 1997.
Financial statements for the years ended December 31, 1994, 1995 and 1996 are
not consolidated since the Company had no subsidiaries during those periods.
 
  Interim Financial Information
 
     The consolidated financial statements for the three months ended March 31,
1996 and 1997 are unaudited but include all adjustments (consisting only of
normal recurring adjustments) that the Company considers necessary for a fair
presentation of financial position and results of operations. Operating results
for the three months ended March 31, 1997 are not necessarily indicative of the
results that may be expected for any future periods.
 
  Operating Cycle
 
     Balance sheet items expected to be paid or received within one year are
classified as current. Assets and liabilities relating to long-term construction
contracts are included in current assets and current liabilities in the
accompanying balance sheet, since they will be realized or liquidated in the
normal course of contract completion, although completion may require more than
one year.
 
  Revenue and Cost Recognition
 
     The Company performs its services primarily under fixed-price contracts and
recognizes revenues and costs from construction projects using the percentage of
completion method. Under this method, revenue is recognized based upon the ratio
of the costs incurred to date to the total estimated costs to complete the
project. Revenue recognition begins when progress is sufficient to estimate
final results with reasonable accuracy. Costs include all direct material and
labor costs related to contract performance, subcontractor costs, indirect
labor, and fabrication plant overhead costs, which are charged to contract costs
as incurred. Revenues relating to changes in the scope of a contract are
recognized when the customer has authorized the change, the work is commenced
and the Company has made an estimate of the amount that is probable of being
paid for the change. Revisions in estimates during the course of contract work
are reflected in the accounting period in which the facts requiring the revision
become known. Provisions for estimated losses on uncompleted contracts are made
in the period a loss on a contract becomes determinable.
 
     Construction contracts with customers generally provide that billings are
to be made monthly in amounts which are commensurate with the extent of
performance under the contracts. Contract receivables arise principally from the
balance of amounts due on progress billings on jobs under construction.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
     (THE INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
                                   UNAUDITED)
 
contract receivables are amounts due on progress billings which are withheld
until the completed project has been accepted by the customer.
 
     Costs and recognized earnings in excess of billings on uncompleted
contracts primarily represent revenue earned under the percentage of completion
method which has not been billed, and also include costs incurred in excess of
the billings on contracts for which sufficient work has not been performed to
allow for the recognition of revenue. Billings in excess of related costs and
recognized earnings on uncompleted contracts represent amounts billed on
contracts in excess of the revenue allowed to be recognized under the percentage
of completion method on those contracts.
 
  Cash and cash equivalents
 
     Cash consists of cash in noninterest bearing checking accounts. Cash
equivalents consist of investments in a money market mutual fund which is
invested in financial instruments and securities issued and guaranteed by the
U.S. Treasury, the U.S. government or its agencies or instrumentalities. All
such investments are completely liquid and are made through the Company's bank
pursuant to an investment and custody agreement.
 
  Restricted Funds on Deposit
 
     Restricted funds on deposit represent funds in an interest bearing escrow
account which is maintained in lieu of contract receivable retentions for a
specific contract.
 
  Inventories
 
     Inventories, primarily steel components which have been charged to specific
contracts, are stated at the lower of cost or market under the first-in,
first-out method.
 
  Property and Equipment
 
     Property and equipment is stated at cost and is depreciated over the
estimated useful lives, which generally range from five to ten years, of the
related assets using the straight line method. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life.
Amortization of leasehold improvements is included in depreciation and
amortization.
 
  Income Taxes
 
     In 1987, the stockholders of the Company elected under Subchapter S of the
Internal Revenue Code to include the Company's income in their own income for
federal and state income tax purposes. As a result, the Company was not subject
to federal or state income taxes at December 31, 1996. At December 31, 1996, the
Company's tax basis differed from the amounts used for financial reporting
purposes. The income tax basis was higher by approximately $750,000.
Accordingly, if the Company converted to a C corporation as of December 31,
1996, it would have recorded a net deferred tax asset of approximately $300,000
and recorded a deferred tax benefit of the same amount to reflect the tax effect
of cumulative differences at conversion. At December 31, 1996 and March 31,
1997, retained earnings included approximately $9,900,000 and $10,700,000,
respectively, of income taxed directly to stockholders.
 
  Fair Value of Financial Instruments
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments", requires that the Company disclose
estimated fair values of financial instruments. Cash and cash equivalents,
restricted funds on deposit, receivables, accounts payable, and other accrued
liabilities are

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
     (THE INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
                                   UNAUDITED)
 
carried at amounts that reasonably approximate their fair values. The Company
believes the carrying amount of their long-term debt approximates fair value at
December 31, 1996.
 
  Concentrations of Credit Risk
 
     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash investments and
receivables. The Company maintains cash and cash equivalents, restricted funds
on deposit and certain other financial instruments with large financial
institutions. The Company performs periodic evaluations of the relative credit
standing of those financial institutions that are considered in the Company's
investment strategy. Concentrations of credit risk with respect to receivables
are limited as the Company's customers tend to be larger general contractors on
adequately funded projects and the Company has certain lien rights.
 
  Use of Estimates
 
     The preparation of the Company's consolidated financial statements in
conformity with generally accepted accounting principles necessarily requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the balance sheet date and the reported amounts of revenues and expenses during
the reporting period for long-term contracts.
 
     The Company has a substantial history of making reasonably dependable
estimates of the extent of progress towards completion, contract revenues, and
contract costs on its long-term contracts. The estimates inherent in such
provisions are periodically evaluated and revisions are made as required to
reflect the most up-to-date information. However, due to uncertainties inherent
in the estimation process, actual results could differ materially from those
estimates.
 
  Long-Lived Assets
 
     The Company adopted the provisions of Financial Accounting Standards Board
Statement No. 121 (FAS 121), "Accounting for the Impairment of Long-Lived Assets
to Be Disposed Of", which requires impairment losses to be recorded on
long-lived assets used in operations, such as equipment and improvements and
intangible assets, when indicators of impairment are present and the
undiscounted cash flows estimated to be generated by those assets are less than
the carrying amount of the assets. Based upon its assessment as of December 31,
1996 and March 31, 1997, management does not believe there are any adjustments
required to its long-lived assets as a result of implementing FAS 121.
 
  Pro Forma Net Income Data
 
     Pro forma net income per share is computed using weighted average common
shares outstanding and common stock equivalents if dilutive. Pro forma tax
provision is based on the effective tax rate that the Company believes would
have been incurred had the Company not been a S corporation for income tax
purposes. That rate of 40% is comprised of a 34% federal statutory rate plus an
effective state tax rate net of federal benefit of 6%. Under Securities and
Exchange Commission Staff Accounting Bulletin 83, common stock equivalents
include the dilutive effect of stock options granted within one year of an
initial public offering at prices less than the anticipated offering price for
all years presented.
 
  Impact of Recently Issued Accounting Standards
 
     Statement of Financial Accounting Standards No. 128 (FAS 128), "Earnings
Per Share", issued by the Financial Accounting Standards Board in February 1997,
is effective for periods ending after December 15,
 
                                       F-9

1997. At that time, the Company will be required to change the method currently
used to compute earnings per share and to restate all prior periods. Under the
new requirements for calculating primary earnings per share, the dilutive effect
of stock options will be excluded. The impact is expected to result in an
increase in pro forma primary earnings per share for the year ended December 31,
1996 of $0.05 and for the quarters ended March 31, 1996 and 1997 of $0.00 and
$0.01, respectively. The impact of FAS 128 on the calculation of fully diluted
pro forma earnings per share for these periods is not expected to be material.

     The Company's revolving line of credit agreement is subject to renewal on
June 30, 1998 and is collateralized by contract receivables, equipment and raw
materials inventory. This agreement permits the Company to borrow up to an
amount equal to 75 percent of qualifying contract receivables and in total shall
not exceed $6,500,000, with further reductions to availability based upon, among
other restrictions, billings in excess of costs levels. As of December 31, 1996
and March 31, 1997, there was no availability for future borrowings under the
Company's revolving line of credit agreement. On March 31, 1997, the Company
modified its revolving line of credit agreement to permit borrowings of up to
$1,000,000 regardless of availability under the formula. The agreement was
subsequently modified to temporarily increase the minimum borrowing permitted
regardless of the formula to $2,500,000 through July 31, 1997. The Company made
interest payments on its line of credit of $272,160, $271,653, and $63,798 for
the years ended December 31, 1994, 1995 and 1996, respectively, and $48,366 and
$4,701 for the three months ended March 31, 1996 and 1997, respectively.
 
     The subordinated note payable to a related party is a long-term loan from a
partnership owned by related parties which include the Company's stockholders.
The partnership obtained the funds loaned to the Company from a bank under terms
similar to those included in the loan it made to the Company. In April 1996, the
partnership refinanced its loan with the same bank used by the Company. Under
the terms of the new loan agreement between the partnership and the bank, the
Company has guaranteed repayment of the partnership's loan, which amounted to
$2,921,736 at December 31, 1996 and $2,883,954 at March 31, 1997.
 
     Principal amounts of long-term debt maturing subsequent to December 31,
1996 are: 1997 -- $144,444, 1998 -- $144,444 and 1999 -- $2,608,396. The Company
made interest payments of $402,959, $449,439 and $420,050 for the years ended
December 31, 1994, 1995 and 1996, respectively, and $133,747 and $55,419 for the
three months ended March 31, 1996 and 1997, respectively, on its long-term debt.

6. EMPLOYEE BENEFIT PLANS
 
     The Company maintains a 401(k) retirement savings plan which covers
eligible employees and which permits participants to contribute to the plan,
subject to Internal Revenue Code restrictions. The plan also permits the Company
to make discretionary matching contributions, which amounted to $34,952 during
the year ended December 31, 1996 (none in 1994 or 1995) and $8,738 and $10,065
for the three month periods ended March 31, 1996 and 1997, respectively.
 
     In 1996, the Company adopted the "Supplemental Retirement and Deferred
Compensation Plan" for certain management employees. The Plan is an unfunded
deferred compensation plan whereby the Company contributes an amount equal to 10
percent of annual net profits after deducting distributions payable to
stockholders, as defined in the Plan. During the year ended December 31, 1996,
total expense recognized by the Company was $528,900, which is currently
scheduled for distribution to eligible employees in 1997. This plan was
terminated effective January 1, 1997.
 
     Substantially all of the Company's fabrication and erection workforce is
subject to collective bargaining agreements. The Company made contributions to
union sponsored benefit plans of $764,013, $883,225 and $1,122,119 during the
years ended December 31, 1994, 1995 and 1996, respectively, and $176,572 and
$409,148 during the three months ended March 31, 1996 and 1997, respectively.
Information from the administrators of these plans is not available to permit
the Company to determine its share of accumulated benefits and related assets.
 
     The Company has a 401(k) defined contribution retirement savings plan for
union steelworkers. Currently, only participants contribute to this plan on a
voluntary basis, subject to Internal Revenue Code restrictions. All account
balances are 100 percent vested.
 
     The Company has a second noncontributory defined benefit plan that is
maintained for union steelworkers and provides for pension and disability
benefits. During 1989, the Company reached agreement with the local
representatives of the United Steelworkers of America to freeze all pension
credits effective December 31, 1988. All pension credits are 100 percent vested.
The unfunded portion of the plan is being reduced by continued contributions by
the Company. The Company currently contributes 60 cents for each hour worked by
each participant. The Company's funding policy is to make monthly contributions
to the plan sufficient to at least meet minimum funding amounts required by law.
 
     Currently, the plan is party to an insurance contract whereby the insurer
provides benefits under the plan. Company contributions are held by the insurer
in a collective investment fund which is managed by the insurer and which is
invested in stocks, bonds and money market instruments. The net assets available
for plan benefits are reflected at contract value, which approximates market
value.
 
     The Company accounts for pension expense under its noncontributory defined
benefit pension plan under the provisions of Statement of Financial Accounting
Standards No. 87, "Employers' Accounting for Pensions."
 
     The weighted average discount rate used in determining the actuarial
present value of accumulated and projected benefit obligations was decreased
from 7.0 percent in 1995 to 6.5 percent in 1996. As a result of this change, the
projected benefit obligation increased by $207,242. The expected long-term rate
of return on plan assets was 8.5 percent in both 1995 and 1996. The weighted
average rate of compensation increase is not applicable because the benefit is
not pay related.

7. STOCKHOLDERS' EQUITY
 
     Due to the Company's income tax status as a qualified S corporation, only
one class of stock may be issued and outstanding, and all outstanding shares
must be identical as to the rights of the holders in the profits and assets of
the Company, although differences in voting rights are permitted.
 
     The Company has the authority to issue a total of two hundred thousand
shares of no par value stock, of which fifty thousand shares must be Class A
Common Stock, fifty thousand shares must be Class B Common Stock, and one
hundred thousand shares must be Preferred Stock. The Class A Common Stock and
the Class B Common Stock are identical in all respects except that the holders
of the Class B Common Stock have no voting power for any purpose and are not
entitled to notice of any meeting of stockholders. As of December 31, 1995 and
1996, only Class A Common Stock had been issued (See Note 13).
 
     The Company also has the authority to issue preferred stock in amounts with
such designations, preferences, voting rights, privileges and such other
restrictions and qualifications as the Board of Directors may, by resolution,
establish. The Company has not set aggregate or per share amounts at which
preferred shares may be called or are subject to redemption through sinking fund
operations or otherwise. No preferred stock has been issued.
 
     It is the policy of the Company to also make distributions to stockholders
in such amounts as are required to enable them to pay income taxes attributable
to their allocable share of taxable income from the Company. Pursuant to
provisions in the Company's revolving line of credit agreement, the Company is
also permitted at its discretion to declare an annual dividend to the
stockholders providing the Company maintains certain financial criteria.

8. STOCK OPTIONS
 
     The Company established a qualified stock option plan ("the Plan")
effective February 5, 1997. The exercise price of the options, as well as the
vesting period, are established by the Company's Board of Directors. A summary

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
     (THE INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
                                   UNAUDITED)
 
     All options granted in 1997 had an exercise price of $5.00 per share which
was equal to the fair value of the Company's common stock, at the date of grant,
as estimated by its Board of Directors. The weighted-average remaining
contractual life of those options is approximately five years.
 
     The Company's 1997 Stock Option Plan has authorized the grant of options up
to 600,000 shares to officers, directors or key employees of the Company. All
options have ten year terms and generally vest ratably over five years from the
date of grant. The fair value of options granted during the three months ended
March 31, 1997 was $1.26.
 
     The Company has elected to follow Accounting Principles Board Opinion
Number 25 (APB 25), "Accounting for Stock Issued to Employees", and related
interpretations in accounting for its stock options issued to employees because,
as discussed below, the alternative fair value accounting provided for under
Statement of Financial Accounting Standards No. 123 (FAS 123), "Accounting for
Stock-Based Compensation", requires use of option valuation models that were not
developed for use in valuing stock options. Under APB 25, because the exercise
price of the Company's employee stock options equals the fair value of the
underlying stock on the date of grant, no compensation expense is recognized.
 
     Pro forma information regarding net income and pro forma earnings per share
is required by FAS 123, and has been determined as if the Company had accounted
for its employee stock options under the fair value method of FAS 123. The fair
value for these options was estimated at the date of grant using a Black Scholes
Option pricing model with the following weighted-average assumptions:

</TABLE>
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models requires the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting periods. The Company's
pro forma net income under FAS 123 is not materially different from historical
results.
 
9. RELATED PARTY TRANSACTIONS
 
     The Company leases certain property from a partnership owned by related
parties including the Company's stockholders. Effective March 1, 1997, the
Company terminated the existing lease and executed a new 20-year lease with the
same partnership. The lease requires monthly lease payments ranging from $24,611
in 1997 to $50,427 in 2000 and thereafter with additional stipulated rent
increases every five years based on the Consumer Price Index. The Company is
also obligated to pay the partnership any taxes related to the lease payments.
Rent expense under the related party lease totaled $252,683, $263,561, and
$273,570 for the years

     (THE INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS
                                   UNAUDITED)
 
11. OTHER INCOME
 
     During 1995, the Company received $175,000 as a result of a settlement with
third parties relating to damages to Company equipment. In addition, the Company
received $371,194 from a claim related to misappropriation of funds by a former
employee.
 
12. CONTINGENCIES
 
     The Company is involved from time to time through the ordinary course of
business in certain claims, litigation, and assessments. Due to the nature of
the construction industry, the Company's employees from time to time become
subject to injury, or even death, while employed by the Company. The Company
does not believe there are any such contingencies at December 31, 1996 for which
the eventual outcome would have a material adverse impact on the Company.
 
     During 1996, the primary contractor on the Company's largest contract has
claimed that the Company was liable under delay provisions and is seeking
damages. While the Company believes that the reasons for the delay were such
that the Company should not be liable, the Company has reduced expected revenues
by approximately $900,000 due to this uncertainty.
 
     During 1996, the Company was named as a defendant in a lawsuit relating to
an incident at one of its worksites whereby one of its employees was killed in a
crane accident. The Company believes the loss, if any, relating to the incident
will be fully insured and does not expect the ultimate outcome of the matter to
have a material adverse impact on its financial position.
 
     Relating to the incident set forth in the prior paragraph, the Company has
been named as a defendant in a lawsuit brought by the crane operator who claims
he was assaulted by employees of the Company after the incident. The Company's
insurance carrier has declined coverage. However, management does not expect the
amount of loss, if any, relating to the ultimate resolution of this matter to
have a material adverse impact on its financial position.
 
13. SUBSEQUENT EVENT
 
     On January 31, 1997, the Company acquired 100 percent of the outstanding
capital stock of B&K Steel Fabrications, Inc. ("B&K"), a steel fabricator
located in Gilbert, Arizona, for $1,223,194, consisting of $426,944 in cash and
$796,250 in two promissory notes payable in annual installments over five years
including interest at 5.73 percent. In addition, the Company prepaid $1,090,000
of the subordinated note payable discussed in Note 5 to enable a related party
lessor to the Company to acquire the real property upon which B&K is located,
and certain equipment attached to the property. The acquisition was not
significant to the Company under the definitions used by the Securities and
Exchange Commission, and will be accounted for under the purchase method of
accounting. After assigning fair values to the tangible assets acquired, and
liabilities assumed, there was no goodwill generated by the purchase. The
results of operations of B&K will be included in those of the Company commencing
February 1, 1997. Had the purchase taken place as of January 1, 1996, the
combined business would have had revenues of $113,291,000, income before taxes
of $18,097,000, pro forma net income (using a 40 percent effective tax rate) of
$6,099,000 and pro forma net income per share of $1.18. However, such
information may not be indicative of future operations of the combined business.
 
     Subsequent to March 31, 1997 the Company entered into a lease agreement
with a partnership owned by related parties including the Company's stockholders
for additional office space acquired by the partnership that is adjacent to the
Company's existing principal office and shop facilities. The lease commences May
1, 1997 and expires on April 30, 2017. The lease requires monthly rental
payments of $11,250, subject to increase

every five years based on a Consumer Price Index formula. In conjunction with
the lease, the Company has guaranteed the related debt incurred by the
partnership to acquire the property in the amount of $999,999.
 
     On May 8, 1997, the Company effected a 50,000 for one common stock split.
Accordingly, all shares of common stock have been restated in the financial
statements to reflect the effect of this stock split. At the same time, the
Company also reincorporated in Delaware and changed its authorized shares and
classes of stock. The information set forth in the financial statements reflect
the authorized shares after having given effect to the reincorporation.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company's Certificate of Incorporation provides that a director of the
Company shall not be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director, except for
liability for: (i) any breach of the director's duty of loyalty to the Company
or its stockholders; (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law; (iii) liability for
payments of dividends or stock purchases or redemptions in violation of Section
174 of the Delaware General Corporation Law; or (iv) any transaction from which
the director derived an improper personal benefit. In addition, the Company's
Certificate of Incorporation provides that the Company shall to the fullest
extent authorized by the Delaware General Corporation Law, as the same exists or
may hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the corporation to provide broader
indemnification rights than such law permitted the corporation to provide prior
to such amendment), indemnify and hold harmless any person who was or is a
party, or is threatened to be made a party to or is otherwise involved in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative by reason of the fact that such person
is or was a director or officer of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, including
service with respect to an employee benefit plan (hereinafter an "Indemnitee")
against expenses, liabilities and losses (including attorneys' fees, judgments,
fines, excise taxes or penalties paid in connection with the Employee Retirement
Income Security Act of 1974, as amended, and amounts paid in settlement)
reasonably incurred or suffered by such Indemnitee in connection therewith;
provided, however, that except as otherwise provided with respect to proceedings
to enforce rights to indemnification, the Company shall indemnify any such
Indemnitee in connection with a proceeding (or part thereof) initiated by such
Indemnitee only if such proceeding or part thereof was authorized by the board
of directors of the Company.
 
     The right to indemnification set forth above includes the right to be paid
by the Company the expenses (including attorneys' fees) incurred in defending
any such proceeding in advance of its final disposition; provided, however,
that, if the Delaware General Corporation Law requires, an advancement of
expenses
 
                                      II-1
<PAGE>   75
 
incurred by an Indemnitee in his capacity as a director or officer (and not in
any other capacity in which service was or is rendered by such Indemnitee,
including, without limitation, service to an employee benefit plan) shall be
made only upon delivery to the Company of an undertaking, by or on behalf of
such Indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is not further right to
appeal that such Indemnitee is not entitled to be indemnified for such expenses
under this section or otherwise. The rights to indemnification and to the
advancement of expenses conferred herewith are contract rights and continue as
to an Indemnitee who has ceased to be a director, officer, employee or agent and
inures to the benefit of the Indemnitee's heirs, executors and administrators.
 
     The Delaware General Corporation Law provides that indemnification is
permissible only when the director, officer, employee, or agent acted in good
faith and in a manner reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the conduct was unlawful. The
Delaware General Corporation Law also precludes indemnification in respect of
any claim, issue, or matter as to which an officer, director, employee, or agent
shall have been adjudged to be liable to the Company unless and only to the
extent that the Court of Chancery or the court in which such action or suit was
brought shall determine that, despite such adjudication of liability but in view
of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.
 
     The Company has agreed to indemnify the Underwriters and their controlling
persons, and the Underwriters have agreed to indemnify the Company and its
controlling persons, against certain liabilities, including liabilities under
the Securities Act. Reference is made to the Underwriting Agreement filed as

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
     On May 8, 1997, the Company reincorporated from Arizona to Delaware by way
of a merger in which the predecessor of the Company, an Arizona corporation,
merged with and into a newly created Delaware subsidiary of the Company. In the
merger, each share of the Arizona corporation's issued and outstanding common
stock was exchanged for 50,000 shares of the Delaware corporation's common stock
and each option to purchase one share of the Arizona corporation's common stock
was exchanged for 50,000 options to purchase shares of the Delaware
corporation's common stock. All share figures set forth above give effect to
this exchange ratio. Exemption from registration for this transaction was
claimed pursuant to Section 4(2) of the Securities Act regarding transactions by
an issuer not involving any public offering and/or pursuant to Rule 145 under
the Securities Act regarding transactions the sole purpose of which is to change
an issuer's domicile solely within the United States.
 
     On February 5, 1997, the Company granted stock options to purchase a total
of 6.91 shares of its common stock at an exercise price of $250,000 per share.
All of these options vest over a five year period with 20% of such options of
each grantee vesting on each anniversary of the date of grant. After the
reincorporation, the options were exchanged for 345,500 options to purchase the
Company's Common Stock at an exercise price of $5.00 per share. Exemption from
restriction for these transactions was claimed pursuant to Section 4(2) of the
Securities Act regarding transactions by an issuer not involving any public
offering.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denomination and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For the purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4), or 497(b) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein and this offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

            B. Consultant is experienced in the investment banking field and
familiar with the steps necessary to assist a closely-held business in becoming
a publicly held company.

            C. The Company is willing to engage Consultant to perform consulting
services for its benefit and is willing to pay Consultant a reasonable fee for
those services.

            D. The parties hereto desire to enter into this Agreement upon the
terms and conditions hereinafter set forth.

<PAGE>   2
            2. CONSULTING FEE. In consideration of Consultant's performance of
the services referred to in Paragraph 1 for the term hereof, the Company agrees
to pay to Consultant a consulting fee in an amount equal to one-half percent
(1/2%) of the capital raised in the public offering, payable as follows:

                  (a) FIFTEEN THOUSAND DOLLARS ($15,000.00) shall be payable
      upon execution of this Agreement; and

                  (b) The remaining balance shall be due and payable upon
      completion of the public offering.

            3. TERM. The term of this Agreement shall commence on the date
hereof and continue for one (1) year, ending on January 15, 1998.
Notwithstanding anything else to the contrary herein, either party can terminate
this Agreement upon fourteen (14) days written notice to the other party.

            4. CONFIDENTIAL INFORMATION. It is expressly understood and agreed
that all trade secrets and know-how of the Company are confidential and are the
sole property of the Company. Consultant shall have no right to possession of
such trade secrets and know-how other than in the discharge of its duties
hereunder. Consultant shall not divulge to third parties the content of any
trade secrets which may have been acquired by virtue of this Agreement. The
obligations provided for in this Paragraph 0 shall survive any termination of
this Agreement.

            5. LIABILITY OF CONSULTANT. In the course of carrying out his duties
as obligated under this Agreement, Consultant shall be liable only for gross
negligence, bad faith or breach of an expressed provision of this Agreement, but
in all other respects, shall not be liable to the Company for any mistake of
judgment. If the Company becomes liable or responsible for the payment of any
debt, encumbrance, liability or judgment arising out of or resulting from
Consultant's performance under this Agreement, and the payment of such debt,
encumbrance, liability or a judgment did not arise through the gross negligence
or bad faith of Consultant, the Company shall indemnify Consultant for any and
all such expense.

            6. INDEPENDENT CONTRACTOR STATUS. Consultant is providing services
to the Company only for the purposes and to the extent set forth in this
Agreement, and Consultant's relation to the Company shall at all times during
the term of this Agreement be that of an independent contractor. Consultant
shall not be considered as having employee status or as being entitled to
participate in any plans, arrangements, or distributions by the Company
pertaining to or in connection with any pension plan, stock plan, bonus plan,
profit sharing plan or similar plan or benefit for the Company's employees.

            7. COST AND EXPENSES. The Company shall reimburse Consultant for
reasonable out-of-pocket costs and expenses incurred by Consultant in connection
with the




                                     - 2 -
<PAGE>   3
performance of his duties as described herein; provided, however, before
incurring any costs and expenses relating to travel or entertainment, Consultant
shall obtain the prior written approval of the Company. Failure to obtain such
written approval before incurring such costs and expenses shall negate the
Company's responsibility for their reimbursement hereunder.

            8. NOTICES. Any notices, statements, payments or other
communications by the parties hereto to the other party shall be directed to the
address set forth below:

                Board of Directors may thereafter (except where otherwise
                provided in the Preferred Stock Designation) increase or
                decrease (but not below the number of shares thereof then
                outstanding).

                         C. The amounts payable on, and the preferences, if any,
                of shares of the series in respect of dividends, and whether

                of shares of the series in the event of any voluntary or
                involuntary liquidation, dissolution or winding up of the
                affairs of the Corporation.

                other corporation, and, if so, the specification of such other
                class or series of such other security, the conversion or
                exchange price or prices or rate or rates, any adjustments
                thereof, the date or dates at which such shares shall be
                convertible or exchangeable and all other terms and conditions

<PAGE>   3
                The Corporation shall be entitled to treat the person in whose
name any share of its stock is registered as the owner thereof for all purposes
and shall not be bound to recognize any equitable or other claim to, or interest
in, such share on the part of any other person, whether or not the Corporation
shall have notice thereof, except as expressly provided by applicable law.

                                   ARTICLE SIX

                Except as otherwise provided in this Certificate of
Incorporation, the Board of Directors of the Corporation shall have the power to
make, alter or repeal the Bylaws of the Corporation. With respect to the power
of the stockholders of the Corporation to make, alter or repeal the Bylaws of
the Corporation, notwithstanding anything contained in this Certificate of
Incorporation or any provision of law that might otherwise require a lessor
vote, the Bylaws may not be made, altered or repealed by the stockholders, and
no provision inconsistent therewith shall be adopted by the stockholders,
without the affirmative vote of the holders of at least seventy-five percent
(75%) of the voting power of all of the shares of the Corporation entitled to
vote generally in the election of directors, voting together as a single class.

                                  ARTICLE SEVEN

                Election of members to the Board of Directors need not be by
written ballot unless the Bylaws of the Corporation shall so provide.

                Meetings of the stockholders of the Corporation may be held
within or without the State of Delaware, as the Bylaws may provide. The books of
the Corporation may be kept (subject to any provision contained in the Delaware
General Corporation Law) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the
Bylaws of the Corporation.

                                  ARTICLE EIGHT

                A director of the Corporation shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders; (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law; (iii) under Section 174 of the Delaware General Corporation
Law; or (iv) for any transaction from which the director derived an improper
personal benefit. If the Delaware General Corporation Law is amended to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law, as so amended. Any repeal or modification of this
provision shall not adversely affect any right or protection of a director of
the Corporation existing at the time of such repeal or modification. The
limitation of liability provided herein shall continue after a director has
ceased to occupy such position as to acts or omissions occurring during such
director's term of terms of office.

<PAGE>   4
                                  ARTICLE NINE

                A. The Corporation shall to the fullest extent authorized by the
Delaware General Corporation Law, as the same exists or may hereafter be amended
(but, in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than such law
permitted the Corporation to provide prior to such amendment), indemnify and
hold harmless any person who was or is a party, or is threatened to be made a
party to or is otherwise involved in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative by reason of the fact that such person is or was a director or
officer of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "Indemnitee") against
expenses, liabilities and losses (including attorneys' fees, judgments, fines,
excise taxes or penalties paid in connection with the Employee Retirement Income
Security Act of 1974, as amended, and amounts paid in settlement) reasonably
incurred or suffered by such Indemnitee in connection therewith; provided,
however, that except as provided in this section with respect to proceedings to
enforce rights to indemnification, the Corporation shall indemnify any such
Indemnitee in connection with a proceeding (or part thereof) initiated by such
Indemnitee only if such proceeding or part thereof was authorized by the Board
of Directors of this Corporation.

                B. The right to indemnification conferred in this section shall
include the right to be paid by the Corporation the expenses (including
attorneys' fees) incurred in defending any such proceeding in advance of its
final disposition; provided, however, that, if the Delaware General Corporation
Law requires, an advancement of expenses incurred by an Indemnitee in his
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such Indemnitee, including, without limitation,
service to an employee benefit plan) shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such Indemnitee, to repay all
amounts so advanced if it shall ultimately be determined by final judicial
decision from which there is not further right to appeal that such Indemnitee is
not entitled to be indemnified for such expenses under this section or
otherwise. The rights to indemnification and to the advancement of expenses
conferred in this section shall be contract rights and such rights shall
continue as to an Indemnitee who has ceased to be a director, officer, employee
or agent and shall inure to the benefit of the Indemnitee's heirs, executors and
administrators.

                C. If a claim under the two preceding paragraphs of this section
is not paid in full by the Corporation within sixty (60) days after a written
claim has been received by the Corporation, except in the case of a claim for an
advancement of expenses, in which case the applicable period shall be twenty
(20) days, the Indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. If successful in whole or
in part in any such suit, or in a suit brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the Indemnitee
shall be entitled to be paid also the expense of prosecuting or defending such
suit. In (i) any suit brought by the

                                        4
<PAGE>   5
Indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by the Indemnitee to enforce a right to an advancement of expenses) and
(ii) in any suit brought by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the Corporation shall be
entitled to recover such expenses upon a final adjudication that the Indemnitee
has not met any applicable standard for indemnification set forth in the
Delaware General Corporation Law. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
suit that indemnification of the Indemnitee is proper in the circumstances
because the Indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) that the Indemnitee has not met such applicable standard of
conduct, shall create a presumption that the Indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Corporation to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the Indemnitee is not
entitled to be indemnified, or to such advancement of expenses under this
section or otherwise, shall be on the Corporation.

                D. The rights to indemnification and advancement of expenses
conferred in this section shall not be exclusive of any other rights which any
person may have or hereafter acquire under any statute, this Corporation's
Certificate of Incorporation, as it may be amended or restated from
time-to-time, any agreement, vote of stockholders or disinterested directors, or
otherwise. No amendment or repeal of this Article Nine shall apply to or have
any effect on any right to indemnification provided hereunder with respect to
any acts or omissions occurring prior to such amendment or repeal.

                E. The Corporation shall have the power to purchase and maintain
insurance, at its expense, to protect itself and any director, officer, employee
or agent of the Corporation or another corporation, partnership, joint venture,
trust or other enterprise (including an employee benefit plan) against any
expense, liability or loss, whether or not the Corporation would have the power
to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law. The Corporation may also create a trust fund,
grant a security interest and/or use other means (including, but not limited to,
letters of credit, surety bonds and/or similar arrangements), as well as enter
into contracts providing indemnification to the full extent authorized or
permitted by law and including as part thereof provisions with respect to any or
all of the foregoing, to ensure the payment of such amounts as may become
necessary to effect indemnification as provided therein, or elsewhere.

                F. For purposes of this section, references to the "Corporation"
shall include any subsidiary of this Corporation from and after the acquisition
thereof by this Corporation, so that any person who is a director, officer,
employee or agent of such subsidiary after the acquisition thereof by this
Corporation shall stand in the same position under the provisions of this
section as such person would have had had such person served in such position
for this Corporation.

<PAGE>   6

                G. The Corporation may, to the extent authorized from time to
time by the Board of Directors, grant rights to indemnification and to the
advancement of expenses to any employee or agent of the Corporation to the
fullest extent of the provisions of this section with respect to the
indemnification and advancement of expenses of directors and officers of the
Corporation.

action that cause exists and such disinterested directors have recommended
removal to the stockholders, or (ii) as otherwise provided by law. A director
may not be removed from office prior to the expiration of his term except as
provided herein.

Corporation, shall be final.

Corporation may hold meetings both regular and special, either within or without
the State of Delaware. Regular meetings of the Board of Directors may be held

such committee by means of a conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
each other, and participation in a meeting pursuant to this Section 3.7 shall
constitute presence in person at such meeting.

                  Section 3.8 Committees. The Board of Directors may, by
resolution passed by a majority of the entire Board of Directors, designate one
or more committees, each committee to consist of one or more of the directors of
the Corporation. The Board of Directors may designate one or more directors as

member at any meeting of any such committee. In the event of the absence or
disqualification of a member of a committee, and in the absence of a designation
by the Board of Directors of an alternate member to replace the absent or
disqualified member, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any absent or disqualified member. A majority of the
members of a committee, including any alternate members, shall constitute a
quorum of such committee. Any committee, to the extent allowed by law and

expenses, if any, of attendance at each meeting of the Board of Directors and
may be paid a fixed sum for attendance at each meeting of the Board of Directors
or a stated salary as director. No such payment shall preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor. Members of special or standing committees may be allowed like
compensation for attending committee meetings. In addition, the Board of
Directors may adopt one or more director compensation plans using securities of
the Corporation.

between the Corporation and one or more of its directors or officers, or between
the Corporation and any other corporation, partnership, association, or other
organization in which one or more of the Corporation's directors or officers are
directors or officers, or have a financial interest, shall be void or voidable
solely for this reason, or solely because the director or officer is present at
or participates in the meeting of the Board of Directors or committee thereof
which authorizes the contract or transaction, or solely because such director's
vote is counted for such purpose if (i) the material facts as to such director's
relationship or interest and as to the contract or transaction are disclosed or
are


                                       6

affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (ii) the material facts as to
such director's relationship or interest and as to the contract or transaction
are disclosed or are known to the stockholders entitled to vote thereon, and the
contract or transaction is specifically approved in good faith by a vote of the
stockholders; or (iii) the contract or transaction is fair as to the Corporation

a committee thereof, or the stockholders. Interested directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee that authorizes the contract or transaction.

        Re:     Registration Statement on Form S-1

Ladies and Gentlemen:

        We have acted as counsel to Schuff Steel Company, a Delaware
corporation (the "Company"), in connection with the preparation and filing with
the United States Securities and Exchange Commission under the Securities Act
of 1933, as amended (the "Securities Act"), of the Company's Registration
Statement on Form S-1 (the "Registration Statement"), relating to the
registration of 2,530,000 shares of the Company's Common Stock, par value $.001
per share (the "Common Stock"). In arriving at the opinions expressed below, we
have reviewed the Registration Statement and the exhibits thereto. In addition,
we have reviewed the originals or copies certified or otherwise identified to
our satisfaction of all such corporate records of the Company and such other
instruments and other certificates of public officials, officers and
representatives of the Company and such other persons, and we have made such
investigation of law as we have deemed appropriate as a basis for the opinions
expressed below. In rendering the opinions expressed below, we have assumed
that the signatures on all documents that we have reviewed are genuine and that
the Common Stock conforms in all material respects to the description thereof
set forth in the Registration Statement.

        Based upon the foregoing, we advise you that, in our opinion, when the
following events have occurred:

        (a)  The Registration Statement has become effective under the
Securities Act;

        (b)  The due authorization, registration, and delivery of the
certificate or certificates evidencing the Common Stock has occurred;

        (c)  The due authorization, execution and delivery of the Underwriting
Agreement; 

        (d)  The compliance with all applicable contracts, agreements, and
instruments in respect of the issuance of the Common Stock; and

        (e)  The Common Stock is issued and sold and consideration has been
received therefore in the manner specified in the Registration Statement and
the exhibits thereto; then

        The Common Stock to be issued by you will be legally issued, fully paid
and non-assessable.


        The foregoing opinion is limited to the federal law of the United
States of America and the General Corporation Law of the State of Delaware. We
express no opinion as to the application of the various state securities laws
to the offer, sale, issuance or delivery of the Common Stock.

        We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Registration Statement and in the Prospectus included therein.

                                        Very truly yours,

                                        SNELL & WILMER L.L.P.

consideration of Bank making said loan the Borrower hereby warrants and agrees

following collateral under duly executed security documents and agrees to be
bound by the terms contained therein:

S/A - INVENTORY, RECEIVABLES AND RIGHTS TO PAYMENT
S/A - EQUIPMENT

      4. NET WORTH. A minimum tangible net worth of $6,100,000.00 and a minimum
owner's equity of 21.0% shall be maintained where "Owner's Equity" "Owner's
Equity Percentage" shall mean the results obtained by dividing (A) Tangible Net
Worth (as herein defined) by (B) Borrower's Total Assets on a six month average.

shall be maintained in excess of current liabilities by $4,900,000.00 and a

current assets by current liabilities after deducting short term advances to

Credit will be considered to be a current liability for the purpose of
calculating both "Net Working Capital" and "Current Ratio".

shall not exceed $N/A during any 12-month period, without prior consent of Bank.

      7. LEASING OF CAPITAL EQUIPMENT. No lease of personal property will be

will be subordinated to Bank's loan in a manner satisfactory to Bank:

maturity. The rate of interest agreed to shall include the interest rate as
shown above, in accordance with the terms of this note, plus any compensating
balance requirement and any additional charges, costs and fees incident to this
loan to the extent they are deemed to be interest under applicable Arizona law.
It is expressly agreed by Borrower that the maximum outstanding principal at any
one time on this note shall not exceed the amount of ONE MILLION AND 00/100
DOLLARS ($1,000,000.00), and the amount outstanding on this note at any specific
time shall be the total amount advanced hereunder by Bank less the amount of
principal payments made hereon from time to time by Borrower. All amounts
payable hereunder shall be paid in lawful money of the United States. Should the
rate of interest as calculated under this note exceed that allowed by law, the
applicable rate of interest will be the maximum rate of interest allowed by
applicable law.

      Principal and interest shall be payable at the Commercial Banking Center
office of Bank One, Arizona, NA in Phoenix, Arizona, or at such other place as
the holder hereof may designate. At Bank's option, any payments may be applied
first to accrued interest and then to principal. All past-due payments of
principal or interest shall bear interest from their due date until paid at a
rate of interest 2% per annum higher than the interest rate specified above or
12% per annum, whichever is higher, payable on demand.

      This note shall become immediately due and payable at the option of the
holder hereof without presentment or demand or any notice to Borrower or any
other person obligated hereon, upon default in the payment of any of the
principal hereof or any interest thereon when due, or in payment under any other
agreement between Borrower and Bank, or if any event occurs or condition exists
which authorized the acceleration of the maturity hereof under any security
agreement, mortgage, deed of trust or other agreement made by Borrower in favor
of Bank. Failure to exercise this option shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default.

      In the event any holder hereof utilizes the services of an attorney in
attempting to collect the amounts due hereunder or to enforce the terms hereof
or of any agreements related to this indebtedness, or if any holder hereof
becomes party plaintiff or defendant in any legal proceeding in relation to the
property described in any instrument securing this note or for the recovery or
protection of the indebtedness evidenced hereby, Borrower, its successors and
assigns, shall repay to such holder hereof, on demand, all costs and expenses so
incurred, including reasonable attorneys' fees, including those costs, expenses
and attorneys' fees incurred after the filing by or against the Borrower of any
proceeding under any chapter of the Bankruptcy Act, or similar federal or state
statute, and whether incurred in connection with the involvement of any holder
hereof as creditor

      Borrower and all sureties, endorsers and guarantors of this note waive
demand, presentment for payment, notice of non-payment, protest, notice of
protest and all other notice, filing of suite and diligence in collecting this
note or the release of any party primarily or secondarily liable hereon and
further agree that it will not be necessary for any holder hereof, in order to

its remedies against any maker or others liable herefor, and consent to any
extension or postponement of time of payment of this note or any other
indulgence with respect hereto without notice thereof to any of them.

      Bank and Borrower will establish specific instructions and procedures by
which draws against said credit will be presented for disbursement, but nothing
contained herein shall create a duty on the part of Bank to make said
disbursement if Borrower is in default.

                            REVOLVING LINE OF CREDIT
                                 LOAN AGREEMENT
                       (ACCOUNTS RECEIVABLE AND INVENTORY)

This agreement is entered into by and between Schuff Steel Company, an Arizona 
corporation ("Borrower") and Bank One, Arizona, NA ("Bank").

RECITALS:

Borrower desires to obtain from Bank a revolving line of credit ("Loan") and
Bank is willing to make the Loan, but only on the terms and conditions
hereinafter set forth. 

NOW, THEREFORE in consideration of the premises and the mutual promises herein
contained and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

1. LOAN.

1.1 REVOLVING LINE OF CREDIT. Subject to the terms and conditions contained
herein and in the other documents, instruments and agreements executed in
connection with the Loan and the security therefor ("Loan Documents"), Bank will
establish for Borrower the Loan as a revolving line of credit against which Bank
will make advances ("Advances") from time to time for the purpose of providing
working capital to Borrower. Subject to the terms hereof, Borrower shall have
the right to obtain Advances, repay Advances and obtain additional Advances;
however, all of the Advances hereunder shall be viewed as a single loan. At no
time shall the unpaid principal balance of the Loan exceed the amount set forth
in Section 13 hereof ("Maximum Amount") and all Advances of the Loan shall be
made on or before the date set forth in Section 13 hereof.

1.2 ADVANCES. Subject to the terms and conditions hereof, Advances of the Loan
will be made in amounts not to exceed the amount ("Borrowing Base") calculated
in accordance with the formula set forth in the Borrowing Base Certificate,
attached hereto as Exhibit A and by this reference incorporated herein. In
calculating the Borrowing Base, the percentage set forth in Section 13 hereof of
the amount of Total Eligible Accounts Receivable and the percentage set forth in
Section 13 hereof of the amount (determined on the basis of the lower of cost or
market value) of Total Eligible Inventory shall be used. "Eligible Account
Receivable" is an amount owing to Borrower, as determined by Bank in its sole
and absolute discretion, which has arisen from the delivery and/or shipment of
products previously made and from services rendered for which an invoice has
been issued by Borrower to its customer ("Customer") (a) which amount is not
subject to any offset, counterclaim or defense asserted by the Customer, (b)
which amount is subject to a perfected security interest in favor of Bank and is
not subject to any other security interest, lien, claim or encumbrances, (c)
which amount has not remained unpaid for more than the number of days set forth
in Section 13 after the date due under the terms of the related invoice, (d)
where not more than fifteen percent (15%) of the total amount owing from the
Customer has remained unpaid for more than the number of days set forth in
Section 13 after the date due under the terms of the related invoice, (e) which
amount is not an uninsured amount owing from Customer located in a foreign
country and (f) which amount is not owing from the United States of America or
any agency, department or subdivision thereof, unless a properly executed
assignment of claims has been received by Bank. "Eligible Inventory" is the
inventory of Borrower (consisting of those items within the categories set forth
in Section 13), as determined by Bank in its sole and absolute discretion, to be
(a) in good condition and salable in the ordinary course of Borrower's business,
(b) owned by Borrower free and clear of any mortgages, liens, security
interests, claims, encumbrances or rights of others, excepting only the security
interests in favor of Bank, (c) located at a location identified in a Security
Agreement (hereinafter defined), (d) subject to a perfected security interest in
favor of Bank, (e) not subject to any consignment to any Customer and (f) not
acquired by Borrower in or as part of a bulk transfer of sale or assets unless
Borrower has complied with all applicable bulk sales or bulk transfer laws.

1.3 NOTE. The Loan shall be evidenced by a promissory note ("Note") of even date
herewith in a form prepared and approved by Bank in the Maximum Amount, payable
in accordance with the terms thereof. Interest on the principal amount
outstanding from time to time shall be charged as provided in the Note and
should such rate of interest as calculated thereunder exceed that allowed by
law, the applicable rate of interest will be the maximum rate of interest
allowed by applicable law.

1.4 PREPAYMENTS. If for any reason the aggregate principal amount of the Loan
outstanding at any time shall exceed the maximum amount permitted to be borrowed
in accordance with Section 1.2 hereof, Borrower, without notice or demand, shall
immediately make a principal payment to Bank in an amount equal to such excess
plus accrued and unpaid interest hereon. Borrower may from time to time, prepay
all or part of the outstanding principal balance of the Loan.

1.5 REMITTANCE ACCOUNT. If so indicated in Section 13 hereof, the proceeds
received by Borrower from its inventory and collection of accounts receivable,
which, pursuant to the Security Agreements (hereinafter defined), are required
to be transmitted to Bank, shall be handled and administered by Bank in and
through a remittance account in accordance with the provisions of the Security
Agreements.

2. SECURITY.

2.1 SECURITY AGREEMENTS. As security for the payment of the Note, the Loan, and
all other liabilities and obligations of Borrower to Bank, now existing or
hereafter created, Borrower shall grant to Bank a security interest in all of
Borrower's inventory, accounts receivable, rights to payment and such other
property ("Property"), as more particularly described in one or more security
agreements ("Security Agreements") executed by Borrower and delivered to Bank in
form and substance satisfactory to Bank, in its sole and absolute discretion.
The Security Agreements shall grant to Bank a first and prior security interest
in and to the Property, except as otherwise expressly provided therein.

3. ADVANCES.

3.1 CONDITIONS PRECEDENT TO ADVANCES. Bank shall have no obligation to make any
Advance until the conditions set forth in the following subparagraphs and
elsewhere herein have been satisfied at the expense of Borrower, as determined
by Bank in its sole and absolute discretion:

   (a) Borrower shall have delivered to Bank, in form and substance satisfactory
   to Bank, this Agreement, the Note, the Security Agreements and such other
   documents, instruments, financing statements, certificates and agreements as
   Bank may reasonably request;

   delivered to Bank, in form and substance satisfactory to Bank in its sole and
   absolute discretion certified copies of resolutions of Borrower's board of
   directors or partners, as the case may be, authorizing Borrower to execute,
   deliver, honor and perform the Loan Documents and to grant the security
   interest in the Property as provided in the Security Agreements and
   certifying the names and signatures of the officers or partners, as the case
   may be, of Borrower authorized to sign the Loan Documents;

   (c) All of Bank's liens and security interests securing the Loan, shall have
   been validly perfected;

   (d) No material adverse change shall have occurred in the business or
   financial condition of Borrower or any guarantor since the date of the latest
   financial statements given to Bank by on behalf of Borrower or such
   guarantor;

   (e) Each of the warranties and representations made by Borrower in the Loan
   Documents shall be true and correct as of the date of each Advance; and

   (f) Borrower shall have kept and performed the various covenants, obligations
   and agreements on its part to be kept and performed under the Loan Documents
   and no Event of Default, or act or event which with the giving of notice or

   or under any of the other Loan Documents, shall have occurred and be
   continuing.

3.2 REQUEST FOR ADVANCES. Advances may be made by Bank at the oral or written
request of the persons named in Section 13 hereof, either one acting alone, who
are authorized to request Advances and direct disposition of any such Advances
until written notice of the revocation of such authority is received from
Borrower by Bank. Each request by Borrower for an Advance shall constitute a
reaffirmation, as of the date of such request, of all of the representations and
warranties of Borrower contained in this Agreement and in the other Loan
Documents.

3.3 NO WAIVER. No Advance shall constitute a waiver of any of the conditions to
any further Advances nor, in the event Borrower is unable to satisfy any such
condition, shall any such Advance have the effect of precluding Bank from
thereafter declaring such inability to be an Event of Default (as hereinafter
defined).

4. FEES.

4.1 FEES. As additional consideration for Bank's commitment to make Advances,
Borrower agrees to pay to Bank the following fees, which shall be non-refundable
to Borrower, shall be held and retained by Bank as its sole property and shall
not be applied to any payments due under the Loan Documents other than this
Section 4:

   or before the date hereof;

   (b) a non-utilization fee computed at the rate per annum set forth in Section
   13 hereof on the unused portion of the Maximum Amount and payable quarterly
   in arrears to be calculated from the date hereof, where the phrase "unused
   portion of the Maximum Amount" means the average difference between (i) the
   Maximum Amount and (ii) the outstanding principal balance of the Loan on each
   day during such period; and

   (c) an inspection fee in the amount per inspection set forth in Section 13
   hereof, payable within ten (10) days of Borrower being billed therefor by

                                (VARIABLE RATE)

Phoenix, Arizona                                                 June 30, 1995


         FOR VALUE RECEIVED, the undersigned ("Borrower"), promises to pay on or
before June 30, 1997 to BANK ONE, ARIZONA, NA, ("Bank"), or order, the aggregate
principal amount outstanding on Borrower's revolving line of credit as shown on
Bank's records which shall at all times be conclusive and govern, with interest
payable monthly on the unpaid balance outstanding from time to time at an annual
rate equal to one quarter* percent (0.250%) more than the "prime rate" of
interest charged by Bank One, Arizona, NA, as such rate shall change from time
to time during the term hereof. Interest is to be charged on a daily basis for
the actual number of days the principal is outstanding from the date of
disbursement to date of maturity. The rate of interest agreed to shall include
the interest rate as shown above, in accordance with the terms of this note,
plus any compensating balance requirement and any additional charges, costs and
fees incident to this loan to the extent they are deemed to be interest under
applicable Arizona law. It is expressly agreed by Borrower that the maximum
outstanding principal at any one time on this note shall not exceed the amount
of SIX MILLION FIVE HUNDRED THOUSAND AND NO/100THS DOLLARS ($6,500,000.00), and
the amount outstanding on this note at any specific time shall be the total
amount advanced hereunder by Bank less the amount of principal payments made
hereon from time to time by Borrower. All amounts payable hereunder shall be
paid in lawful money of the United States. Should the rate of interest as
calculated under this note exceed that allowed by law, the applicable rate of
interest will be the maximum rate of interest allowed by applicable law.

         Principal and interest shall be payable at the Commercial Banking
Center office of Bank One, Arizona, NA in Phoenix, Arizona, or at such other
place as the holder hereof may designate. At Bank's option, any payments may be
applied first to accrued interest and then to principal. All past-due payments
of principal or interest shall bear interest from their due date until paid at a
rate of interest 2% per annum higher than the interest rate specified above or
12% per annum, whichever is higher, payable on demand.

         This note shall become immediately due and payable at the option of the
holder hereof without presentment or demand or any notice to Borrower or any
other person obligated hereon, upon default in the payment of any of the
principal hereof or any interest thereon when due, or in payment under any other
agreement between Borrower and Bank, or if any event occurs or condition exists
which authorizes the acceleration of the maturity hereof under any security
agreement, mortgage, deed of trust or other agreement made by Borrower in favor
of Bank. Failure to exercise this option shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default.

*See Addendum attached hereto

         In the event any holder hereof utilizes the services of an attorney in
attempting to collect the amounts due hereunder or to enforce the terms hereof
or of any agreements related to this indebtedness, or if any holder hereof
becomes party plaintiff or defendant in any legal proceeding in relation to the
property described in any instrument securing this note or for the recovery or
protection of the indebtedness evidenced hereby, Borrower, its successors and
assigns, shall repay to such holder hereof, on demand, all costs and expenses so
incurred, including reasonable attorneys' fees, including those costs, expenses
and attorneys' fees incurred after the filing by or against the Borrower of any
proceeding under any chapter of the Bankruptcy Act, or similar federal or state
statute, and whether incurred in connection with the involvement of any holder
hereof as creditor in such proceedings or otherwise.

         Borrower and all sureties, endorsers and guarantors of this note waive
demand, presentment for payment, notice of non-payment, protest, notice of
protest and all other notice, filing of suit and diligence in collecting this
note or the release of any party primarily or secondarily liable hereon and
further agree that it will not be necessary for any holder hereof, in order to
enforce payment of this note by any of them, to first institute suit or exhaust
its remedies against any maker or others liable herefor, and consent to any
extension or postponement of time of payment of this note or any other
indulgence with respect hereto without notice thereof to any of them.

         Bank and Borrower will establish specific instructions and procedures
by which draws against said credit will be presented for disbursement, but
nothing contained herein shall create a duty on the part of Bank to make said

ADDENDUM TO REVOLVING LINE OF CREDIT NOTE, DATED JUNE 30, 1995, 1995 ("ORIGINAL
         NOTE"), BETWEEN SCHUFF STEEL COMPANY , AN ARIZONA CORPORATION
         ("BORROWER") AND BANK ONE, ARIZONA, NA, A NATIONAL BANKING ASSOCIATION
         ("BANK"),IN THE ORIGINAL PRINCIPAL AMOUNT OF $ 6,500,000.00.

         This Addendum is hereby incorporated into the Original Note as if fully
set forth therein. This Addendum and the Original Note shall be read together as
a consistent agreement. To the extent of any necessary inconsistency between the
two, however, the terms and provisions of this Addendum shall control. The
integrated agreement of the Original Note and this Addendum is herein called the
Note.

SECTION 1.  RECITALS.

         1.1 In the Revolving Line of Credit Loan Agreement, dated JUNE 30, 1995
("LOAN AGREEMENT"), between Borrower and Bank, Bank has agreed to extend to
Borrower credit up to $ 6,500,000.00. Borrower may obtain advances (individually
an "ADVANCE" and collectively the "ADVANCES") as provided in the Loan Agreement.

         1.2 Interest on Advances, as provided in the Note, is at the rate per
annum ("VARIABLE RATE") equal to sum of (i) one quarter percent (0.25%) and (ii)
the rate per annum most recently publicly announced by Bank, or its successors,
in Phoenix, Arizona, as its "prime rate", as in effect from time to time. The
Variable Rate will change on each day that the "prime rate" changes. The "prime
rate" is not necessarily the best or lowest rate offered by Bank, and Bank may
lend to its customers at rates that are at, above, or below its "prime rate".

         1.3 The purpose of this Addendum is to provide for some or all Advances
to bear interest at a fixed rate at the election of Borrower, all as more
specifically provided in this Addendum.

SECTION 2  DEFINITIONS.  As used in the Note:

         "BUSINESS DAY" means a day of the year on which banks are not required

Loan, a day on which dealings are carried on in the London interbank market.

         "FIXED RATE" means the rate per annum equal to the sum of (i) two and
one-half percent (2.50%) per annum, and (ii) the rate of interest determined by
Bank, based on Telerate System reports (Page 3807) or such other source as may
be selected by Bank, to be the rate at which deposits in United States dollars
are offered by major banks in London, England, to other major banks in the
London interbank market at 11:00 a.m. (London, England, local time) on the first
day of the Interest Period for the period in the London interbank market equal
to or next greater than the Interest Period.

         "FIXED RATE LOAN" means a Loan that bears or is requested to bear
interest at the Fixed Rate.

         "INTEREST PERIOD" means, for each Fixed Rate Loan, the period
commencing on the date selected by Borrower and ending on the last day of the
period selected by Borrower as provided herein and, thereafter, each subsequent
period commencing on the last day of the immediately preceding Interest Period
and ending on the last day of the period selected by Borrower as provided
herein. The duration of each Interest Period shall be thirty (30), sixty (60),
or ninety (90) days, as selected by Borrower as provided herein, provided,
however, that:

         (a) Interest Periods commencing on the same date shall be of the same
duration;

         (b) Whenever the last day of an Interest Period would otherwise occur
on a day other than a Business Day, the last day of the Interest Period shall be
extended to occur on the next succeeding Business Day, provided, however, that
if the extension would cause the last day of the Interest Period to occur in the
next following calendar month, the last day of the Interest Period shall occur
on the next preceding Business Day;

         (c) No Interest Period shall extend beyond the Maturity Date; and

         (d) As to a Fixed Rate Loan less than $1,000,000, the Interest Period
must start on a Business Day that is one of the last five (5) days of a calendar

         "VARIABLE RATE LOAN" means a Loan that bears or that is requested to
bear interest at the Variable Rate.

SECTION 3  INTEREST RATE.

         3.1 Except to the extent that unpaid Advances bear interest at the
Fixed Rate, interest shall accrue on unpaid Advances at the Variable Rate.

         3.2 In connection with any Advance, Borrower may elect on any Business
Day, upon notice that is received by Bank not later than 12:00 p.m. (Phoenix,
Arizona, local time) on such Business Day, that such Advance shall be a Fixed

not later than 12:00 p.m. (Phoenix, Arizona local time) on such Business Day,
convert any amount previously advanced under the Loan Agreement from one type of
Loan into the other type of Loan or continue a Fixed Rate Loan as a Fixed Rate
Loan for a new Interest Period, provided, that Borrower may make an election to
convert a Fixed Rate Loan to a Variable Rate Loan or to continue a Fixed Rate
Loan as a Fixed Rate Loan only on the last day of the Interest Period. Each such
notice of conversion or continuation shall specify (i) the date of such
conversion or continuation, (ii) the amount to be converted or continued, and
(iii) if applicable, the Interest Period. Any Advance not complying with the
foregoing requirements for an Advance bearing interest at the Fixed Rate shall

Period for such Fixed Rate Loan, at the Fixed Rate.

         3.4 Interest at the Variable Rate shall be computed on the basis of a
365 day year and accrue on a daily basis for the actual number of days elapsed.
Interest at the Fixed Rate shall be computed on the basis of a 360 day year and
shall accrue on a daily basis for the actual number of days elapsed.

         3.5 Notwithstanding any provision of the Loan Agreement to the
contrary:

             3.5.1 Bank shall be entitled to fund and maintain its funding of 
all or any part of any Fixed Rate Loan in any manner it sees fit.

             3.5.2 If prior to the commencement of any Interest Period, Bank
determines by reason of circumstances affecting the London interbank market,
adequate and reasonable means do not exist for ascertaining the Fixed Rate for
such Interest Period in the manner provided in the definition of "Fixed Rate",
then Bank shall promptly give notice thereof to Borrower and the respective
amount as to which Borrower has requested the Fixed Rate shall bear interest at
the Variable Rate.

             3.5.3 A Fixed Rate Loan must be in a minimum amount of $500,000. If
at any time a Fixed Rate Loan becomes less than $500,000, Bank, at its option,
may convert the Fixed Rate Loan to a Variable Rate Loan.

SECTION 4. PREPAYMENT AND CONVERSION PREMIUM. Borrower may prepay the
outstanding principal balance hereof, in whole or in part, at any time prior to
the Maturity Date. With any such prepayment of a Fixed Rate Loan or with a
conversion election of a Fixed Rate Loan to a Variable Rate Loan, in either case
other than on the last Business Day of the Interest Period for such Fixed Rate
Loan ("INTEREST PERIOD TERMINATION DATE") (whether made voluntarily or
involuntarily as a result of an acceleration of the Maturity Date or otherwise),
Borrower shall also pay (a) all accrued and unpaid interest on the principal
being prepaid, (b) all Other Amounts then due, and (c) a prepayment premium, if
any, equal to the product of (i) the Average Lost Monthly Interest Income and
(ii) the number of months from the date of prepayment to the Interest Period
Termination Date (with any fraction of a month counted as a month), discounted
to present value at the Discount Rate over a period equal to one-half of the
number of months in (ii) above. At the option of Bank, in its absolute and sole
discretion, any prepayment shall be applied to installments coming due under the
Note in the inverse order of their due dates.

BANK, in its absolute and sole discretion and without notice, may terminate the
commitment to issue Letters of Credit.

         15.2 Issuance Procedure. To obtain a Letter of Credit, BORROWER shall
complete and execute a Letter of Credit Agreement and submit it to the letter of
credit department of BANK. Upon receipt of a completed and executed Letter of
Credit Agreement, BANK will process the application in accordance with the
policies, procedures, and requirements of BANK then in effect. If the
application meets the requirements of BANK and is within the policies of BANK
then in effect, BANK will issue the requested Letter of Credit.

         15.3 Reimbursement of BANK for Payment of Drafts Drawn or Drawn and
Accepted Under Letters of Credit. The obligation of BORROWER to reimburse BANK
for payment by BANK of drafts drawn or drawn and accepted under a Letter of
Credit shall be as provided in the respective Letter of Credit Agreement. BANK
will notify BORROWER of payment by BANK of a draft drawn or drawn and accepted
under a Letter of Credit and of the respective Reimbursement Amount and will
give BORROWER the election (i) to pay the Reimbursement Amount pursuant to the
respective Letter of Credit Agreement or (ii) to pay the Reimbursement Amount by
BANK making an Advance subject to the terms and conditions of this Agreement and
applying the proceeds of the Advance to pay the Reimbursement Amount. If

<PAGE>   4
BORROWER does not communicate to BANK its election within two Business Days
after notification by BANK of payment of the draft or acceptance, BORROWER shall
be deemed to have elected to pay the Reimbursement Amount by BANK making an
Advance hereunder, provided that if the terms and conditions in this Agreement
for an Advance hereunder are not satisfied, BORROWER shall be deemed to have
elected to pay the Reimbursement Amount pursuant to the Letter of Credit
Agreement. Each Advance to pay a Reimbursement Amount shall be dated the date
that BANK pays the respective draft or acceptance and shall accrue interest from
and after such date. If BORROWER is to pay the Reimbursement Amount pursuant to
the Letter of Credit Agreement, BORROWER shall also pay to BANK interest on the
Reimbursement Amount from and including the date BANK pays the respective draft
or acceptance at the rate per annum at which interest is then accruing under the
Line of Credit Note until the Reimbursement Amount and such interest are paid in
full, provided that if BORROWER fails to pay the Reimbursement Amount and
accrued interest thereon within five (5) days after notification by BANK to
BORROWER of payment of the respective draft or acceptance, interest thereafter
shall accrue at the interest rate applicable to past-due payments under the Line
of Credit Note. Such interest shall be computed on the basis of a 360-day year
and accrue on a daily basis for the actual number of days elapsed.
Notwithstanding the above, if BORROWER elects or is deemed to have elected to
pay the Reimbursement Amount pursuant to the Letter of Credit Agreement and
fails to pay the Reimbursement Amount and interest thereon within five (5) days
after notification by BANK to BORROWER , BANK, in its absolute and sole
discretion and without notice to BORROWER and regardless of whether the terms
and conditions in this Agreement for Advances are satisfied, may make an Advance
under this Agreement in the amount of the Reimbursement Amount and accrued
interest thereon and apply the proceeds of such Advance to pay the Reimbursement
Amount and accrued interest.

16. Letters of Credit and Advances. Letters of Credit may be issued by BANK at
the oral or written request of the respective person or persons designated in
the Agreement to request Advances. Such person or persons are hereby authorized
by BORROWER to request Letters of Credit and Advances, to execute and deliver
Letter of Credit Agreements on behalf of BORROWER , and to direct disposition of
the proceeds of Advances until written notice of the revocation of such
authority is received from BORROWER by BANK and BANK has had a reasonable time
to act upon such notice. BANK shall have no duty to monitor for BORROWER or to
report to BORROWER the use of Letters or Credit or proceeds of Advances.
Advances shall be disbursed by BANK in the manner agreed upon by BANK and
BORROWER from time to time.

17. Limit on Letters of Credit and Advances. Anything in the Loan Documents to
the contrary notwithstanding, the sum from time to time of (i) the aggregate
amount of outstanding and undrawn Letters of Credit, (ii) the aggregate amount
of outstanding and unpaid drafts drawn or drawn and accepted under Letters of
Credit, (iii) the aggregate amount of unpaid Reimbursement Amounts, and (iv) the
amount of outstanding and unpaid Advances shall not exceed the lesser of (A) the
Maximum Amount and (B) the Borrowing Base, provided, that if such sum at any
time exceeds the lesser of (A) and (B), BORROWER , without notice or demand,
shall immediately make a payment to BANK in an amount equal to the sum of (1)
such excess and (2) accrued and unpaid interest thereon.

18. Collateral Upon Event of Default. Upon an event of default and demand by
BANK in its absolute and sole discretion, BORROWER shall immediately deliver to
BANK, as security for all obligations of Borrower under the Loan Documents
(including, without limitation, the obligation to pay Reimbursement Amounts),
immediately available funds in an amount equal to the sum of (i) the aggregate
amount of outstanding and undrawn Letters of Credit, and (ii) the aggregate
amount of outstanding and unpaid drafts drawn or drawn and accepted under
Letters of Credit. BORROWER hereby grants to BANK a security interest in all
such funds delivered to BANK to secure payment and performance of said
obligations.

19. Conditions Precedent to Each Advance and Letter of Credit. BANK shall be
obligated to issue a Letter of Credit or make an Advance when requested by
BORROWER only if the representations and warranties by the Loan Parties in the
Loan Documents are accurate on and as of the date of this Agreement and on and
as of the date of issuance of the Letter of Credit or of making the Advance
before and after giving effect to the Letter of Credit or the Advance and the
application of the proceeds of the Advance. Delay or failure by BANK to insist
on satisfaction of any condition of issuance of a Letter of Credit or making an
Advance shall not be a waiver of such condition precedent or any other condition
precedent. If BORROWER is unable to satisfy any condition precedent of issuance
of a Letter of Credit or making an Advance, the issuance of the Letter of Credit
or the making of the Advance shall not preclude BANK from thereafter declaring
the condition or event causing such inability to be an event of default.

Bank. The word "Indebtedness" includes any and all loans, debts, obligations and
liabilities of whatever nature of Borrower owed to Bank whenever and however
made, incurred or created, whether recovery upon such Indebtedness may be barred
by any statue of limitations, whether such Indebtedness may be otherwise
unenforceable, and whether Borrower is liable individually or jointly with
others.

      2. The liability of Guarantors shall not exceed at any one time the total
of (i) the principal sum of TEN MILLION AND NO/100THS Dollars ($10,000,000.00)
plus (ii) all interest owed thereon plus (iii) all costs, attorneys' fees,
losses and expenses which may be incurred by Bank by reason of Borrower's
default in the payment of the Indebtedness.

      3. This Guaranty shall bind and obligate the undersigned and their
successors and assigns with Borrower, jointly and severally, for the payment of
the Indebtedness. A separate action may be commenced against Guarantors whether
action is brought against Borrower or whether Borrower may be joined in any such
action. Guarantors waive any defenses Borrower may now or hereafter have to
payment of the Indebtedness.

      4. Guarantors authorize Bank, without notice or demand and without
affecting Guarantors' liability hereunder, to, from time to time: (a) renew,
compromise, extend, revise, accelerate or otherwise change the time for payment
of, or otherwise change the terms of, the Indebtedness or any part thereof (
including the rate of interest thereon); (b) take security for the payment of
this Guaranty or the Indebtedness, and exchange, enforce, waive, or release any

      5. The obligation of the Guarantors shall remain in full force and effect
until the entire Indebtedness shall have been paid, and shall not be affected
upon the happening of any event, including without limitation, any of the
following: (a) the Bank's failure to give notice to the Guarantors of the
occurrence of any event of default in the payment of the Indebtedness or
performance of the Borrower; (b) the Bank's waiver of the payment, performance
or observance by the Borrower of any obligations, covenants or agreements
related in any way to the Indebtedness; (c) the Bank's impairment, modification,
release or amendment of any obligation, covenant or term of any agreement
related to the Indebtedness; (d) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of any of the Borrower's assets or any
insolvency, bankruptcy, reorganization or other similar proceedings affecting
Borrower; or (e) any event or action that would, in the absence of this clause,
result as a matter of law in the release or discharge of the Guarantors from the

Borrowers, Guarantors, or other guarantors; (b) proceed against or exhaust any
security held from Guarantor or Borrowers; or (c) pursue any other remedy in
Bank's power whatsoever. Guarantors waive the benefits of Arizona Revised

and expenses which may be incurred by Bank in the enforcement of this Guaranty.

monies, securities and other property of Guarantors now or hereafter in the
possession of or on deposit with Bank, whether held in a general or special
account, or for safekeeping or otherwise; and every such lien and right of
set-off may be exercised without demand upon, or notice to Guarantors until the
Indebtedness is paid in full.

      10. This Guaranty is cumulative as to amounts and does not revoke or alter
any guaranty previously delivered to Bank or any guaranty subsequently deliver
to Bank. This Guaranty does not in any manner limit the amount of any borrowing
or other financing arrangement between Bank and Borrower.

      11. Guarantors acknowledge that the execution of this Guaranty shall not
entitle Guarantors to rely on the Bank to preserve or maintain any collateral or
other security that Bank may now have or hereafter acquire in connection with
the Indebtedness. Guarantors hereby release Bank from any obligation to inspect,
preserve or maintain any collateral or other security that Bank may now have or
hereafter acquire in connection with the Indebtedness, and any obligation to
monitor, control or see to the use of any monies advanced to the Borrower.

documents to make the agreements on its part herein contained; (b) the execution
of this Guaranty has been authorized by all necessary and proper actions; (c)
the execution and delivery of this Guaranty, the consummation of the

which it is a party or by which it is bound; and (d) Guarantor agrees that
during the term of this Guaranty it will maintain its separate existence, and
will not dissolve, terminate, merge or consolidate.

1.   ACCURACY OF RECITALS.

Borrower acknowledges the accuracy of the Recitals.

2.   MODIFICATION OF LOAN DOCUMENTS.

     2.1  The Loan Documents are modified as follows:

        2.1.1  Section 1.2 of the Loan Agreement is modified to read in its
               entirety as follows:

             1.2  ADVANCES.  Subject to the terms and conditions hereof,
             Advances of the Loan will be made in amounts not to exceed the
             amount ("Borrowing Base") calculated in accordance with the formula
             set forth in the Borrowing Base Certificate, attached hereto as
             Exhibit A and by this reference incorporated herein. In calculating
             the Borrowing Base, the percentage set forth in Section 13 hereof
             of the amount of Total Eligible Accounts Receivable of Borrower and
             B & K Steel Fabrications, Inc., an Arizona corporation ("B&K")
             (collectively, "Entities"), and the percentage set forth in Section
             13 hereof of the amount (determined on the basis of the lower of
             cost or market value) of Total Eligible Inventory of the Entities
             shall be used. "Eligible Account

                                       1
<PAGE>   2
     Receivable" is an amount owing to the Entities, as determined by Bank in
     its sole and absolute discretion, which has arisen from the delivery and/or
     shipment of products previously made and from services rendered for which
     an invoice has been issued by one of the Entities to its customer
     ("Customer") (a) which amount is not subject to any offset, counterclaim or
     defense asserted by the Customer, (b) which amount is subject to a
     perfected security interest in favor of Bank and is not subject to any
     other security interest, lien, claim or encumbrances, (c) which amount has
     not remained unpaid for more than the number of days set forth in Section
     13 after the date due under the terms of the related invoice, (d) where not
     more than fifteen percent (15%) of the total amount owing from the Customer
     has remained unpaid for more than the number of days set forth in Section
     13 after the date due under the terms of the related invoice, (e) which
     amount is not an uninsured amount owing from Customer located in a foreign
     country and (f) which amount is not owing from the United States of America
     or any agency, department or subdivision thereof, unless a properly
     executed assignment of claims has been received by Bank. "Eligible
     Inventory" is the inventory of the Entities (consisting of those items
     within the categories set forth in Section 13), as determined by Bank in
     its sole and absolute discretion, to be (a) in good condition and salable
     in the ordinary course of the Entities' business, (b) owned by one of the
     Entities free and clear of any mortgages, liens, security interests,
     claims, encumbrances or rights of others, excepting only the security
     interests in favor of Bank, (c) located at a location identified in a
     Security Agreement (hereinafter defined), (d) subject to a perfected
     security interest in favor of Bank, (e) not subject to any consignment to
     any Customer and (f) not acquired by any of the Entities in or as part of a
     bulk transfer of sale or assets unless one of the Entities has complied
     with all applicable bulk sales or bulk transfer laws. Notwithstanding
     anything in this paragraph to the contrary, Borrower shall be entitled to
     Advances of the Loan of at least $1,000,000.00 regardless of the Borrowing
     Base calculation.

2.1.2  Section 1.5 of the Loan Agreement is hereby modified to read in its

              (d) Petition by Borrower for reorganization or arrangement under
the bankruptcy laws. 

              (e) Attachment, garnishment, levy of execution, or judicial
seizure of any portion of the collateral which is not dismissed or stayed within

              (f) Insolvency of Borrower. 

              (g) Discontinuance by Borrower of the business or abandonment of
any substantial portion of Borrower's assets. 

              If any event of default shall occur, the whole of the principal
sum then remaining unpaid on all notes and other obligations to Bank, together
with the interest thereon, shall become immediately due and payable at the
election of Bank. If suit is instituted to collect the notes and other
obligations, Borrower promises to pay, in addition to the costs and
disbursements allowed by law, such additional sums as the court may award as
attorney's fees.

Bank's records which shall at all times be conclusive and govern, with interest

to date of maturity. The rate of interest agreed to shall include the interest
rate as shown above, in accordance with the terms of this note, plus any
compensating balance requirement and any additional charges, costs and fees
incident to this loan to the extent they are deemed to be interest under
applicable Arizona law. Bank and Borrower will establish specific instructions

Bank to make said disbursement if Borrower is in default. This note does not
evidence a revolving line of credit and the undersigned shall not be entitled to
total disbursements hereunder exceeding FIVE HUNDRED THOUSAND AND NO/100THS

rate of interest 2% per annum higher than the interest rate specified above or
12% per annum, whichever is higher, payable on demand.

         This note shall become immediately due and payable at the option of the
holder hereof without presentment or demand or any notice to Borrower or any
other person obligated hereon, upon default in the payment of any of the
principal hereof or any interest thereon when due, or in payment under any other
agreement between Borrower and Bank, or if any event occurs or condition exists
which authorized the acceleration of the maturity hereof under any security
agreement, mortgage, deed of trust or other agreement made by Borrower in favor
of Bank. Failure to exercise this option shall not constitute a waiver of the
right to exercise the same in the event of any subsequent default.

                           by (B) Borrower's Total Assets on a six month

            2.1.4 Section 5 of the Agreement is hereby deleted in its entirety 
and replaced with the following:

                  5. Net Working Capital. While the loan is outstanding, current
                  assets shall be maintained in excess of current liabilities by
                  $4,900,000.00 and a current ratio of 1.25:1.0 shall be
                  maintained and calculated by dividing current assets by
                  current liabilities after deducting short term advances to
                  shareholders. The outstanding balance on the $6,500,000.00

4.       Letters of Credit.

         4.1 Issuance of Letters of Credit. Subject to the terms and conditions
of this Agreement and the Letter of Credit Agreements and subject to the
policies, procedures, and requirements of BANK in effect from time to time for

making an Advance subject to the terms and conditions of this Agreement and
applying the proceeds of the Advance to pay the Reimbursement Amount. If DEBTOR

date. If DEBTOR is to pay the Reimbursement Amount pursuant to the Letter of
Credit Agreement, DEBTOR shall also pay to BANK interest on the Reimbursement
Amount from and including the date BANK pays the respective draft or acceptance
at the rate per annum at which interest is then accruing under the Line of
Credit Note until the Reimbursement Amount and such interest are paid in full,
provided that if DEBTOR fails to pay the Reimbursement Amount and accrued
interest thereon within five (5) days after notification by BANK to DEBTOR of
payment of the respective draft or acceptance, interest thereafter shall accrue
at the interest rate applicable to past-due payments under the Line of Credit
Note. Such interest shall be computed on the basis of a 360-day year and accrue
on a daily basis for the actual number of days elapsed. Notwithstanding the
above, if DEBTOR elects or is deemed to have elected to pay the Reimbursement
Amount pursuant to the Letter of Credit Agreement and fails to pay the
Reimbursement Amount and interest thereon within five (5) days after
notification by BANK to DEBTOR, BANK, in its absolute and sole discretion and
without notice to DEBTOR and regardless of whether the terms and conditions in
this Agreement for Advances are satisfied, may make an Advance under this
Agreement in the amount of the Reimbursement Amount and accrued interest thereon
and apply the proceeds of such Advance to pay the Reimbursement Amount and
accrued interest.


<PAGE>   4
5. Letters of Credit and Advances. Letters of Credit may be issued by BANK at
the oral or written request of the respective person or persons designated in
the Agreement to request Advances. Such person or persons are hereby authorized
by DEBTOR to request Letters of Credit and Advances, to execute and deliver
Letter of Credit Agreements on behalf of DEBTOR, and to direct disposition of
the proceeds of Advances until written notice of the revocation of such
authority is received from DEBTOR by BANK and BANK has had a reasonable time to
act upon such notice. BANK shall have no duty to monitor for DEBTOR or to report
to DEBTOR the use of Letters or Credit or proceeds of Advances. Advances shall
be disbursed by BANK in the manner agreed upon by BANK and DEBTOR from time to
time.

6. Limit on Letters of Credit and Advances. Anything in the Loan Documents to
the contrary notwithstanding, the sum from time to time of (i) the aggregate
amount of outstanding and undrawn Letters of Credit, (ii) the aggregate amount
of outstanding and unpaid drafts drawn or drawn and accepted under Letters of
Credit, (iii) the aggregate amount of unpaid Reimbursement Amounts, and (iv) the
amount of outstanding and unpaid Advances shall not exceed the amount of the
Commitment, provided, that if such sum at any time exceeds such amount, DEBTOR,
without notice or demand, shall immediately make a payment to BANK in an amount
equal to the sum of (A) such excess and (B) accrued and unpaid interest thereon.

7. Collateral Upon Event of Default. Upon an event of default and demand by BANK
in its absolute and sole discretion, DEBTOR shall immediately deliver to BANK as
security for all Obligations immediately available funds in an amount equal to
the sum of (i) the aggregate amount of outstanding and undrawn Letters of
Credit, and (ii) the aggregate amount of outstanding and unpaid drafts drawn or
drawn and accepted under Letters of Credit. DEBTOR hereby grants to BANK a
security interest in all such funds delivered to BANK to secure payment and
performance of the Obligations.

8. Conditions Precedent to Each Advance and Letter of Credit. BANK shall be
obligated to issue a Letter of Credit or make an Advance when requested by
DEBTOR only if the representations and warranties by the Loan Parties in the
Loan Documents are accurate on and as of the date of this Agreement and on and
as of the date of issuance of the Letter of Credit or of making the Advance
before and after giving effect to the Letter of Credit or the Advance and the
application of the proceeds of the Advance. Delay or failure by BANK to insist
on satisfaction of any condition of issuance of a Letter of Credit or making an
Advance shall not be a waiver of such condition precedent or any other condition
precedent. If DEBTOR is unable to satisfy any condition precedent of issuance of
a Letter of Credit or making an Advance, the issuance of the Letter of Credit or
the making of the Advance shall not preclude BANK from thereafter declaring the
condition or event causing such inability to be an event of default.

         2.2 Each of the Loan Documents is modified to provide that it shall be
a default or an event of default thereunder if Borrower shall fail to comply
with any of the covenants of Borrower herein or if any representation or
warranty by Borrower herein is materially incomplete, incorrect, or misleading
as of the date hereof.

shall be a reference to such document as modified herein.

                               CONTINUING GUARANTY


TO:      THE BANK ONE, ARIZONA, NA

         1. For valuable consideration, the undersigned (hereinafter called
Guarantors) jointly and severally, unconditionally guarantee and promise to pay
to BANK ONE, ARIZONA, NA (hereinafter called Bank), or order, on demand, in
lawful money or the United States, any and all Indebtedness of 19TH
AVENUE/BUCHANAN LIMITED PARTNERSHIP, an Arizona limited partnership (hereinafter
called Borrowers) to Bank. The word "Indebtedness" is used herein in its most
comprehensive sense and includes any and all advances, debts, obligations and
liabilities of Borrowers, and any and all contracts, letters of credit or
commitments of Bank made for the benefit or at the request of Guarantors or
Borrowers, or any one or more of them, heretofore, now or hereafter made,
incurred or created, whether voluntary or involuntary, and however arising
whether due or not due, absolute or contingent, liquidated or unliquidated,
determined or undetermined, and whether Borrowers may be liable individually or
jointly with others, or whether recovery upon such Indebtedness may be, or
hereafter becomes, barred by any statute of limitations, or whether such
Indebtedness may be, or hereafter becomes, otherwise unenforceable.

         2. The liability of Guarantors shall not exceed at any one time the
total of the principal sum of THREE MILLION TWENTY-TWO THOUSAND FOUR HUNDRED
EIGHTY-FIVE AND NO/100 Dollars ($3,022,485.00) plus all accrued and accruing
interest upon the said guaranteed principal Indebtedness as contracted and
agreed by Borrowers. This Guaranty shall bind and obligate each of the
undersigned, his heirs, legatees, devisees, personal representatives, successors
and assigns, with said Borrower, jointly and severally, for the payment of said
Indebtedness precisely as if the same had been contracted and was due and owing
by him in person. The obligations hereunder are joint and several and
independent of the obligations of Borrowers and a separate action or actions may
be brought and prosecuted against Guarantors whether action is brought against
Borrowers or whether Borrowers be joined in any such action or actions; and
Guarantors waived the benefit of any statute of limitations affecting their
liability hereunder or the enforcement thereof. Guarantors further waive any
action against the Borrowers or Guarantors required by any statute, upon notice.

         3. No revocation hereof shall affect in any manner rights arising under
this Guaranty with respect to (a) liabilities which shall have been created,
contracted, assumed or incurred prior to actual receipt by the Bank of written
notice of such revocation; (b) liabilities which shall have been created,
contracted, assumed or incurred after actual receipt by Bank of such written
notice pursuant to any contract, letter of credit or commitment entered into by
the Bank prior to receipt of such notice, or (c) any of the aforementioned
liabilities arising out of or in any way related to the Indebtedness which shall
have been renewed, modified, extended, consolidated, amended or revised after
revocation of this Guaranty, any or all of which actions are contemplated and
hereby permitted by Guarantors, and this Guaranty shall continue in full force
and effect, and Bank shall have the rights herein provided for, as if no such
revocation had occurred. The sole effect of revocation hereof shall be to
exclude from this Guaranty liabilities and Indebtedness thereafter arising which
are unconnected with (a) liabilities and Indebtedness theretofore arising and
existing, or (b) transactions, contracts, letters of
<PAGE>   2
credit or commitments theretofore entered into or made, which are renewed
modified, extended, consolidated, amended or revised after such revocation. Any
such revocation of this Guaranty at any time or times by one or more of the
undersigned Guarantors shall not affect the liability hereunder of the remaining
Guarantors as to any future transactions or Indebtedness of the Borrowers, but
this Guaranty shall in all respects remain in force and effect as to such
Indebtedness and transactions. The death of any Guarantor shall not operate as a
revocation of liability hereunder of the estate of any such Guarantor as to
transactions entered into or Indebtedness created subsequent to such death until
actual receipt by Bank of written notice of the death of such Guarantor. Each of
the Guarantors severally waives notice of revocation given by any other
Guarantor or Guarantors. Any payment by Guarantors shall not reduce their
maximum obligation hereunder, unless written notice to that effect is actually
received by Bank at, or prior to, the time of such payment. Revocation of this
Guaranty shall not in any way affect the rights, duties, obligations or
liabilities of either Bank or Guarantors hereunder with respect to transactions
occurring or Indebtedness incurred prior to the effectiveness of such
revocation.

         4. Guarantors authorize Bank, from time to time, without notice or
demand and without affecting their liability hereunder, to (a) renew,
compromise, extend, revise, accelerate or otherwise change the time for payment
of, or otherwise change the terms of, the Indebtedness or any part thereof,
including increase or decrease of the rate of interest thereon, before and after
any revocation of this Guaranty; (b) take and hold security for the payment of
this Guaranty or the Indebtedness guaranteed, and exchange, enforce, waive and
release any such security, or take additional security; (c) apply such security
and direct the order or manner of sale thereof as Bank, in its discretion, may
determine; and (d) release or substitute any or more of the endorsers or
Guarantors or acquire additional Guarantors. Bank may, without notice, assign
this Guaranty in whole or in part.

         5. Guarantors waive any right to require Bank to (a) proceed against

permitted by law, Guarantor waives any and all statutes of limitations as a

Guarantor waives any right to require Bank, and Bank shall have no obligation,

<PAGE>   9
performance by Guarantor hereunder, (ii) arising from any application of any
Guarantor Collateral or any other property, interests in property, or rights to
property of Guarantor to payment or performance of the Obligations, or (iii)
otherwise arising in respect of the Guarantor Loan Documents, regardless of
whether such claims, remedies, and rights arise under any present or future
agreement, document, or instrument or are provided by any law, ordinance,
regulation, or rule (federal, state, or local)(including, without limitation,
(A) any and all rights of contribution, exoneration, indemnity, reimbursement,
and subrogation, and (B) any and all rights to participate in the rights and
remedies of Bank against Borrower, any other Loan Parties, and the Collateral).

7.  SUBORDINATION. If from time to time Borrower shall have liabilities or
obligations to Guarantor, such liabilities and obligations and any and all
assignments as security, grants in trust, liens, mortgages, security interests,
other encumbrances, and other interests and rights securing such liabilities and
obligations shall at all times be fully subordinate with respect to (i)
assignment as security, grant in trust, lien, mortgage, security interest, other
encumbrance, and other interest and right (if any), (ii) time and right of
payment and performance, and (iii) rights against any collateral therefore (if
any), to payment and performance in full of the Obligations and the right of
Bank to realize upon any or all Collateral. Guarantor agrees that such
liabilities and obligations of Borrower to Guarantor shall not be secured by any
assignment as security, grant in trust, lien, mortgage, security interest, other
encumbrance or other interest or right in any property, interests in property,
or rights to property of Borrower and that Borrower shall not pay, and Guarantor
shall not receive, payments of any or all liabilities or obligations of Borrower
to Guarantor until after termination of any Commitment, any letters of credit
issued by Bank for Borrower expire or are drawn in full, any drafts drawn or
drawn and accepted under any such letters of credit are paid in full, and
payment and performance of the Obligations in full. If, notwithstanding the
foregoing, Guarantor receives any payment from Borrower, such payment shall be
held in trust by Guarantor for the benefit of Bank, shall be segregated from the
other funds of Guarantor, and shall forthwith be paid by Guarantor to Bank and
applied to payment of the Borrower Obligations, whether or not then due. To
secure the Obligations Guarantor grants to Bank a lien and security interest in
all liabilities and obligations of Borrower to Guarantor, in any assignments as
security, grants in trust, liens, mortgages, security interests, other
encumbrances, other interests or rights securing such liabilities and
obligations, and in all of Guarantor's right, title, and interest in and to any
payments, property, interests in property, or rights to property acquired or
received by Guarantor from Borrower in respect of any liabilities or obligations
of Borrower to Guarantor.

8.  RIGHTS AND REMEDIES OF BANK. The rights and remedies of Bank shall be
cumulative and non-exclusive. Delay, discontinuance, or failure to exercise any
right or remedy of Bank shall not be a waiver thereof, of any other right or
remedy of Bank, or of the time of the essence provision. Exercise of any right
or remedy of Bank shall not cure or waive any Event of Default or invalidate any
act done in response to any Event of Default.

9.  LIMIT OF LIABILITY OF BANK. In exercising rights and remedies, neither Bank
nor any stockholder, director, officer, employee, agent, or representative of
Bank shall have any liability for any injury to the assets, business,
operations, or property of Guarantor or any other liability to Guarantor, other
than for its own gross negligence or willful misconduct.

10. SURVIVAL. The representations, warranties, and covenants of Guarantor in the
Guarantor Loan Documents shall survive the execution and delivery of this
Guaranty.

11. INTEGRATION, ENTIRE AGREEMENT, CHANGE, DISCHARGE, TERMINATION, WAIVER,
APPROVAL, CONSENT, ETC. The Guarantor Loan Documents contain the complete
understanding and agreement of Guarantor and Bank and supersede all prior
representations, warranties, agreements, arrangements, understandings, and
negotiations. No provision of the Guarantor Loan Documents may be changed,
discharged, supplemented, terminated, or waived except in writing signed by the
parties thereto. Delay or failure by Bank to insist on performance of any
obligation when due or compliance with any other term or condition in the
Guarantor Loan Documents shall not operate as a waiver thereof or of any other
obligation, term, or condition or of the time of the essence provision.
Acceptance of late payments or performance shall not be a waiver of the time of
the essence provision, the right of Bank to require that subsequent payments or
performance be made when due, or the right of 


                                    9
<PAGE>   10

not made when due. Any approval, consent, or statement that a matter is
satisfactory by Bank under the Guarantor Loan Documents must be in writing
executed by Bank and shall apply only to the Person(s) and facts specifically
set forth in the writing.

12. BINDING EFFECT. The Guarantor Loan Documents shall be binding upon Guarantor
and shall inure to the benefit of Bank and their successors and assigns and the
executors, legal administrators, personal representatives, heirs, devisees, and
beneficiaries of Guarantor, provided, however, that Guarantor may not delegate
any of its obligations under the Guarantor Loan Documents and any purported
delegation shall be void. Bank may from time to time in its absolute and sole
discretion assign it rights and delegate its obligations under the Loan
Documents, in whole or in part, without notice to or consent by Guarantor
(including, without limitation, participation). In addition to any greater or
lesser limitation provided by law, Guarantor shall not assert against any
assignee of Bank any claims or defenses Guarantor may have against Bank, except
claims and defenses, if any, arising under the Guarantor Loan Documents.

the Guarantor Loan Documents or relating to the Guarantor Collateral, and (vii)
in preparing for the foregoing, whether or not any legal proceeding is brought
or other action is taken. Such costs, expenses, and fees shall include, without
limitation, all such costs, expenses, and fees incurred in connection with any
bankruptcy, receivership, replevin, or other court proceedings (whether at the
trial or appellate level). Guarantor agrees to pay interest on such costs,
expenses, and fees at the Default Rate from the date incurred by Bank until paid
in full.

Loan Documents is unenforceable, the enforceability of the other provisions or
the other provisions and the remainder of the subject provision, respectively,
shall not be affected and they shall remain in full force and effect.

15. CHOICE OF LAW. The Guarantor Loan Documents shall be governed by the laws of
the State of Arizona, without giving effect to conflict of laws principles. If,
notwithstanding this SECTION 15, at any time the law of any jurisdiction other
than the State of Arizona is determined to be applicable to this Guaranty, then
to the maximum extent permitted by law, Guarantor expressly waives any and all
benefits of the law and rules of such jurisdiction that conflict with any
provision of this Guaranty.

the Guarantor Loan Documents as to which time is a factor.

<PAGE>   11
18. JOINT AND SEVERAL OBLIGATIONS.All obligations in any of the Guarantor Loan
Documents executed by more than one Person shall be the joint and several
obligations of each such Person. In each Guarantor Loan Document executed by
more than one Guarantor, each reference to Guarantor, Obligor, or Trustor shall
be a reference to each Person executing such Guarantor Loan Document
individually and all such Persons collectively.

19. COMMUNITY PROPERTY AND SEPARATE PROPERTY OF GUARANTOR. If this Guaranty is
executed by Persons who are married to each other, each such Person agrees that
(i) the Guarantor Loan Documents are made on behalf of the marital community of
each such Person and his or her spouse, and (ii) Bank shall have recourse
against the separate property of each such Person and the community property of
each such Person for satisfaction of the Guarantor Obligations.

20. BANK'S RIGHT OF SET-OFF. Guarantor grants to Bank (i) the right at any time
and from time to time after any Event of Default, in the absolute and sole
discretion of Bank and without demand or notice to Guarantor, to set-off and

special, time, or other, and whether provisional or final) held and any other
liabilities or other obligations of Bank to Guarantor ("DEPOSITS, LIABILITIES,
AND OBLIGATIONS") against or to the Guarantor Obligations, regardless of whether
the Deposits, Liabilities, or Obligations are contingent, matured, or unmatured,
and (ii) a security interest in the Deposits, Liabilities, and Obligations to
secure the Guarantor Obligations. In addition, Guarantor grants to Bank the
right upon occurrence of an event that with notice, passage of time, or both
would be an Event of Default to segregate all Deposits, Liabilities, and
Obligations into an account or otherwise under the sole control of Bank.

21. INDEMNIFICATION OF BANK. Guarantor agrees to indemnify, hold harmless, and
on demand defend Bank and its shareholders, directors, officers, employees,
agents, and representatives for, from, and against any and all damages, losses,
liabilities, penalties, costs, and expenses (including, without limitation,
costs and expenses of litigation and attorneys' fees) arising from any claim or
demand in respect of the Guarantor Loan Documents or any Guarantor Collateral
and arising at any time, whether before or after termination of any Commitment,
any letters of credit issued by Bank for Borrower expire or are drawn in full,
any drafts drawn or drawn and accepted under any such letters of credit are paid
in full, and payment and performance of the Obligations in full. The obligations
of Guarantor and the rights of Bank under this SECTION 21 shall survive
termination of any Commitment, the expiration or drawing in full of any letters
of credit issued by Bank to Borrower, the payment in full of any drafts drawn or
drawn and accepted under any such letters of credit, and payment and performance
of the Obligations in full and shall remain in full force and effect without
termination.

whether before or after termination of any Commitment, any letters of credit
issued by Bank for Borrower expire or are drawn in full, any drafts drawn or
drawn and accepted under any such letters of credit are paid in full, and
payment and performance of the Obligations in full, all or any part of any
amount received by Bank in payment of, or on account of, any Obligation is or
must be, or is claimed to be, avoided, rescinded, or returned by Bank to
Guarantor or any other Person for any reason whatsoever (including, without
limitation, bankruptcy, insolvency, or reorganization of Guarantor or any other
Person), such Obligation and any Liens and Encumbrances that secured such
Obligation at the time such avoided, rescinded, or returned payment was received
by Bank shall be deemed to have continued in existence or shall be reinstated,
as the case may be, all as though such payment had not been received.

23. NO CONSTRUCTION AGAINST BANK OR GUARANTOR. The Guarantor Loan Documents are
the result of negotiations between Guarantor and Bank. Accordingly, the
Guarantor Loan Documents shall not be construed for or against Guarantor or
Bank, regardless of which party drafted the Guarantor Loan Documents or any part
thereof.

24. HEADINGS. The headings at the beginning of each section of the Guarantor
Loan Documents are solely for convenience and are not part of the Guarantor Loan
Documents.

<PAGE>   9

performance by Guarantor hereunder, (ii) arising from any application of any
Guarantor Collateral or any other property, interests in property, or rights to
property of Guarantor to payment or performance of the Obligations, or (iii)
otherwise arising in respect of the Guarantor Loan Documents, regardless of

(A) any and all rights of contribution, exoneration, indemnity, reimbursement,
and subrogation, and (B) any and all rights to participate in the rights and
remedies of Bank against Borrower, any other Loan Parties, and the Collateral).

7. SUBORDINATION. If from time to time Borrower shall have liabilities or
obligations to Guarantor, such liabilities and obligations and any and all
assignments as security, grants in trust, liens, mortgages, security interests,
other encumbrances, and other interests and rights securing such liabilities and
obligations shall at all times be fully subordinate with respect to (i)
assignment as security, grant in trust, lien, mortgage, security interest, other

payment and performance, and (iii) rights against any collateral therefore (if

Bank to realize upon any or all Collateral. Guarantor agrees that such
liabilities and obligations of Borrower to Guarantor shall not be secured by any
assignment as security, grant in trust, lien, mortgage, security interest, other
encumbrance or other interest or right in any property, interests in property,
or rights to property of Borrower and that Borrower shall not pay, and Guarantor
shall not receive, payments of any or all liabilities or obligations of Borrower
to Guarantor until after termination of any Commitment, any letters of credit
issued by Bank for Borrower expire or are drawn in full, any drafts drawn or
drawn and accepted under any such letters of credit are paid in full, and
payment and performance of the Obligations in full. If, notwithstanding the
foregoing, Guarantor receives any payment from Borrower, such payment shall be
held in trust by Guarantor for the benefit of Bank, shall be segregated from the
other funds of Guarantor, and shall forthwith be paid by Guarantor to Bank and
applied to payment of the Borrower Obligations, whether or not then due. To
secure the Obligations Guarantor grants to Bank a lien and security interest in
all liabilities and obligations of Borrower to Guarantor, in any assignments as
security, grants in trust, liens, mortgages, security interests, other
encumbrances, other interests or rights securing such liabilities and
obligations, and in all of Guarantor's right, title, and interest in and to any
payments, property, interests in property, or rights to property acquired or
received by Guarantor from Borrower in respect of any liabilities or obligations
of Borrower to Guarantor.

8. RIGHTS AND REMEDIES OF BANK. The rights and remedies of Bank shall be
cumulative and non-exclusive. Delay, discontinuance, or failure to exercise any
right or remedy of Bank shall not be a waiver thereof, of any other right or
remedy of Bank, or of the time of the essence provision. Exercise of any right
or remedy of Bank shall not cure or waive any Event of Default or invalidate any
act done in response to any Event of Default.

9. LIMIT OF LIABILITY OF BANK. In exercising rights and remedies, neither Bank
nor any stockholder, director, officer, employee, agent, or representative of
Bank shall have any liability for any injury to the assets, business,
operations, or property of Guarantor or any other liability to Guarantor, other
than for its own gross negligence or willful misconduct.

10. SURVIVAL. The representations, warranties, and covenants of Guarantor in
the Guarantor Loan Documents shall survive the execution and delivery of this
Guaranty.

understanding and agreement of Guarantor and Bank and supersede all prior
representations, warranties, agreements, arrangements, understandings, and
negotiations. No provision of the Guarantor Loan Documents may be changed,
discharged, supplemented, terminated, or waived except in writing signed by the
parties thereto. Delay or failure by Bank to insist on performance of any
obligation when due or compliance with any other term or condition in the
Guarantor Loan Documents shall not operate as a waiver thereof or of any other
obligation, term, or condition or of the time of the essence provision.
Acceptance of late payments or performance shall not be a waiver of the time of
the essence provision, the right of Bank to require that subsequent payments or
performance be made when due, or the right of 


                                       9

and shall inure to the benefit of Bank and their successors and assigns and the
executors, legal administrators, personal representatives, heirs, devisees, and

any of its obligations under the Guarantor Loan Documents and any purported
delegation shall be void. Bank may from time to time in its absolute and sole
discretion assign it rights and delegate its obligations under the Loan
Documents, in whole or in part, without notice to or consent by Guarantor
(including, without limitation, participation). In addition to any greater or
lesser limitation provided by law, Guarantor shall not assert against any

or other action is taken. Such costs, expenses, and fees shall include, without
limitation, all such costs, expenses, and fees incurred in connection with any

shall not be affected and they shall remain in full force and effect.

15. CHOICE OF LAW. The Guarantor Loan Documents shall be governed by the laws of
the State of Arizona, without giving effect to conflict of laws principles. If,
notwithstanding this SECTION 15, at any time the law of any jurisdiction other

to the maximum extent permitted by law, Guarantor expressly waives any and all
benefits of the law and rules of such jurisdiction that conflict with any

18. JOINT AND SEVERAL OBLIGATIONS. All obligations in any of the Guarantor Loan
Documents executed by more than one Person shall be the joint and several

special, time, or other, and whether provisional or final) held and any other
liabilities or other obligations of Bank to Guarantor ("DEPOSITS, LIABILITIES,
AND OBLIGATIONS") against or to the Guarantor Obligations, regardless of whether

limitation, bankruptcy, insolvency, or reorganization of Guarantor or any other
Person), such Obligation and any Liens and Encumbrances that secured such
Obligation at the time such avoided, rescinded, or returned payment was received
by Bank shall be deemed to have continued in existence or shall be reinstated,
as the case may be, all as though such payment had not been received.

23. NO CONSTRUCTION AGAINST BANK OR GUARANTOR. The Guarantor Loan Documents are
the result of negotiations between Guarantor and Bank. Accordingly, the

                                      LEASE


                  THIS LEASE is entered into as of the 1st day of March, 1997,
by and between 19th AVENUE/BUCHANAN LIMITED PARTNERSHIP, an Arizona limited
partnership ("Landlord"), and SCHUFF STEEL COMPANY, an Arizona corporation
("Tenant").

ARTICLE 1.        LEASED PREMISES

1.1      Leased Premises. Landlord leases to Tenant the land and improvements
         located at 420 S. 19th Avenue, Phoenix, Arizona, as more particularly
         described on Exhibit "A" ("Leased Premises").

ARTICLE 2.        TERM

2.1      Term of Lease. The term of this Lease shall be twenty (20) years
         commencing on March 1, 1997 and ending on February 28, 2017.

2.2      Quiet Enjoyment. Landlord agrees that so long as the rent is being paid
         in the manner and at the time prescribed and the covenants and
         obligations of Tenant are being all and singularly kept, fulfilled and
         performed, Tenant shall lawfully and peaceably have, hold, possess, use
         and occupy and enjoy the Leased Premises so long as this Lease remains
         in force without hindrance, disturbance or molestation from Landlord,
         subject to the specific provisions of this Lease.

2.3      Surrender of Leased Premises. Upon any termination of this Lease,
         whether by lapse of time, cancellation pursuant to an election provided
         for herein, forfeiture, or otherwise, Tenant shall immediately
         surrender possession of the Leased Premises and all buildings and
         improvements on the same to Landlord in good and tenantable repair,
         reasonable wear and damage from fire or other casualty or peril
         excepted, and shall surrender all keys for the Leased Premises to
         Landlord at the place then fixed for the payment of rent and shall
         inform Landlord of all combinations of locks, safes and vaults, if any,
         in the Leased Premises.

         At any time during the ten (10) days before the termination date of
         this Lease, Tenant, if not in default hereunder at such time, shall
         have the right to remove, and at the end of the term, if directed to do
         so by Landlord, shall remove from the Leased Premises all furniture,
         furnishings, signs, and equipment then installed or in place in, on or
         about the Leased Premises; provided, however, Tenant shall, and it
         covenants and agrees to, make all repairs to the Leased Premises
         required because of such removal. If any of such property shall remain
         on the Leased Premises after the end of the term hereof, such property
         shall be and become the property of Landlord without any claim therein
         of Tenant. Landlord may direct Tenant to remove such property, in which
         case Tenant


                                      - 1 -
<PAGE>   6
         agrees to do so, and to reimburse Landlord for any expense of removal
         in the event Tenant shall fail to remove such property if and when
         directed.

         Upon termination of this Lease, Tenant shall peaceably surrender the
         Leased Premises, including all fixtures and tenant improvements, in a
         neat and broom clean condition, and Tenant shall repair any holes or
         openings made by Tenant in the walls, roof or floor of the building,
         remove any protuberance and perform any maintenance or repairs required
         of Tenant by this Lease. If directed to do so by Landlord, Tenant shall
         also remove any improvements, additions or alterations made to the
         Leased Premises by Tenant even though such improvements by the terms of
         this Lease become a part of the Leased Premises.

2.4      Holding Over. If Tenant, upon expiration or termination of this Lease,
         either by lapse of time or otherwise, remains in possession of the
         Leased Premises with Landlord's written consent but without a new lease
         reduced to writing and duly executed, Tenant shall be deemed to be
         occupying the Leased Premises as a tenant at will, subject to all the
         covenants, conditions and agreements of this Lease. If Tenant remains
         in possession without Landlord's written consent, Tenant shall be
         deemed to be in wrongful holdover and shall be subject to all the
         rights and remedies provided to Landlord under this Lease and the
         applicable laws, including any forcible entry and detainer actions or
         other eviction processes.

2.5      Abandonment. If Tenant, prior to the expiration or termination of this
         Lease by lapse of time or otherwise, relinquishes possession of the
         Leased Premises without Landlord's written consent, such relinquishment
         shall be deemed to be an abandonment of the Leased Premises and an
         event of default under this Lease.

         advance in equal monthly installments on the first day of each calendar
         month thereafter, without prior demand therefor.

         3.2.1    Computation of Adjusted Minimum Rent. The Adjusted Minimum
                  Rent shall be computed based on the increase in the Consumer
                  Price Index - U.S. City average - All Urban Consumers
                  ("Index") as published by the United States Department of
                  Labor's Bureau of Labor Statistics over the base period index.
                  The base period index shall be the index for the calendar
                  month of December 1996. The base period index shall be
                  compared with the Index for the same calendar month for each
                  subsequent December in the year immediately preceding the
                  effective date of each adjustment (comparison month). If the
                  Index for any comparison month is higher than the base period
                  index, then the Minimum Rent for the next succeeding
                  adjustment period shall be increased by the identical
                  percentage commencing with the next succeeding March 1. In no
                  event shall the Minimum Rent be less than that the amount paid
                  immediately prior to any such adjustment.

         3.2.2    Use of Different Index. If the Bureau discontinues the
                  publication of the Index, or publishes it less frequently, or
                  alters it in any manner, then Landlord shall adopt a
                  substitute index or substitute procedure which reasonably
                  reflects and monitors consumer prices.

3.3      Payment of Rent. Tenant shall, without prior notice or demand and
         without any setoff or deduction whatsoever, pay all rentals and other
         charges and render all statements herein prescribed at the Landlord's
         address or to such other person or corporation, and at such other
         place, as shall be designated by Landlord in writing at least ten (10)
         days prior to the next ensuing rental payment date.

3.4      Taxes.

         3.4.1    Rent Tax. Tenant shall pay as additional rent, any privilege
                  tax, sales tax, gross proceeds tax, rent tax or like tax (but
                  not including income tax), now or hereafter levied, assessed
                  or imposed by any federal, state, county or municipal
                  governmental authority, or any subdivision thereof, upon any
                  rent or other payments require to be paid under this Lease.

         3.4.2    Personal Property Tax. Tenant shall pay before delinquent, as
                  additional rent, all personal property taxes and assessments
                  levied or assessed by any governmental authority against any
                  personal property or fixtures of Tenant in, on or about the
                  Leased Premises.

         3.4.3    Real Property Tax. Tenant shall pay before delinquent,
                  exhibiting receipts to Landlord on demand, all real property
                  taxes and assessments levied or assessed against the Leased
                  Premises and improvements thereon, all water charges or


                                      - 3 -
<PAGE>   8
                  assessments levied in connection with any improvements or
                  irrigation projects, or district or other taxes, assessments
                  or governmental charges of any kind levied or assessed against
                  the Leased Premises. Tenant shall have the right, in good
                  faith and at its sole and own cost and expense and in its own
                  name or in the name of Landlord, to protest or contest or seek
                  to have reviewed, reduced, equalized or abated any tax or
                  assessment by legal proceedings in such manner as it may deem
                  advisable. No protest, contest or other action, however, shall
                  be maintained by Tenant after the time limited for the payment
                  without penalty or interest of the tax or assessment unless
                  Tenant shall have first paid the amount of such tax or
                  assessment under protest or shall have procured a stay of
                  proceedings to enforce the collection thereof, and shall have
                  also provided for the payment thereof, together with all
                  penalties, interest, cost and expenses, by the deposit of a
                  bond in form approved by Landlord if required by law to
                  accomplish such stay.

3.5      Interest. Tenant covenants and agrees that all sums to be paid under
         this Lease, if not paid when due, shall bear interest on the unpaid
         portion thereof at the rate of eighteen (18%) per annum from the date
         when due. If Landlord shall pay any monies, or incur any expenses in
         correction of any violation of any covenant of Tenant herein set forth,
         the amounts so paid, or, incurred shall, at Landlord's option and on
         notice to Tenant, be considered additional rentals payable by Tenant
         with the first installment of rental thereafter to become due and
         payable, and may be collected or enforced as by law provided with
         respect to rentals.

3.6      Utilities Consumed on Leased Premises. In addition to all rentals
         herein specified, Tenant shall be responsible for and shall pay for all
         utilities used or consumed in or upon the Leased Premises, and all
         sewer charges, as and when the charges therefor shall become due and
         payable, throughout the term of this Lease. Tenant shall make all
         appropriate applications to the local utility companies and pay all
         required deposits for meters and service for all utilities.

         In the event any utility or utility service (such as water or sewage
         disposal) are furnished to Tenant for which a lien could be filed
         against the Leased Premises or any portion thereof, Tenant shall, at
         Landlord's request, pay the cost thereof to Landlord as and when the
         charges therefor become due and payable; otherwise, Tenant shall
         deliver original receipted bills to Landlord within thirty (30) days
         after the same are due and payable without interest or penalty.

         In no event shall Landlord be liable for any interruption or failure in
         the supply of any utilities to the Leased Premises.

ARTICLE 4. SECURITY

4.1      Landlord's Lien. Landlord shall have a general lien on the leasehold
         estate hereby created and on all property kept or used on the Leased
         Premises, whether such property


                                      - 4 -
<PAGE>   9
         is exempt from execution or not, to secure payment of any and all
         monies then due or thereafter becoming due to Landlord under the terms
         and conditions of this Lease, and to secure the prompt performance and
         fulfillment by Tenant of each and every one of said terms and
         conditions. The lien as provided for in this Paragraph 4.1 attaches as
         of the date of execution hereof and shall remain in full force and 
         effect unless expressly waived by Landlord in writing.

4.2      Security in Addition to Other Remedies. The security given Landlord in
         this Article 4 shall not limit, replace or obviate the remedies of
         Landlord upon a default by Tenant as described in Article 10 below,
         including the right of Landlord to re-enter the Leased Premises,
         distrain for rent or pursue its general lien upon Tenant's property in
         the Leased Premises described in Paragraph 4.1 above.

ARTICLE 5. CONSTRUCTION, ALTERATIONS, MAINTENANCE AND REPAIRS

5.1      Tenant's Duty to Repair. Landlord shall not be called upon to make any
         improvements or repairs of any kind upon the Leased Premises and
         appurtenances unless such repairs are necessitated by the misuse or
         negligence of Landlord. Tenant shall keep and maintain in good order,
         condition and repair (including any such replacement, periodic
         painting, and restoration as is required for that purpose) the Leased
         Premises and every part thereof and any and all appurtenances hereto
         located. Any of the foregoing repairs required to be made by reason of
         the negligence of Landlord shall be the responsibility of the Landlord
         notwithstanding the provisions above contained in this paragraph.

         If Tenant refuses or neglects to commence and to complete repairs or
         maintenance required herein promptly and adequately, Landlord may, but
         shall not be required to, make and complete said repairs, and Tenant
         shall pay the cost thereof to Landlord as additional rent upon demand.
         Except as provided in Paragraph 8.1 (Fire and Casualty damage) and
         8.2 (Condemnation), Landlord shall not be obligated to repair, replace,
         maintain or alter the Leased Premises, and Tenant waives all laws in
         contravention thereof. With regard to repairs, Tenant expressly waives
         any right pursuant to any law now existing or which may be effective
         during the term hereof, to make repairs at Landlord's expense.

5.2      Tenant's Alterations and Improvements to Leased Premises. Tenant shall
         not make or cause to be made any alterations, additions or improvements
         to the building, or make any changes to the exterior of the building
         without first obtaining Landlord's written approval and consent.

         Tenant shall present to the Landlord plans and specifications for such
         work at the time approval is sought. No addition, alteration, change or
         improvement shall be made which


                                      - 5 -
<PAGE>   10
         will weaken the structural strength, lessen the value of, or change the
         architectural appearance of any building or other construction.

         Landlord may condition its approval of any additions or alterations by
         Tenant on the requirement that Tenant or its contractor secure and bear
         the cost of a labor and materials payment bond for the amount of the
         proposed construction reflecting Landlord as an obligee.

         All building materials and fixtures installed by Tenant shall be new or
         completely reconditioned. All alterations, improvements, additions and
         fixtures made or installed by Tenant as aforesaid shall remain upon the
         Leased Premises at the expiration or earlier termination of this Lease
         and shall become the property of Landlord, unless Landlord shall, prior
         to the expiration or termination of this Lease, have given written
         notice to Tenant to remove the same, in which event Tenant shall remove
         the same and restore the Leased Premises to the same good order and
         condition in which it was at the commencement of this Lease. Should
         Tenant fail so to do, Landlord may do so, collecting, at Landlord's
         option, the cost and expense thereof from the Tenant as additional
         rent.

5.3      Furniture, Trade Fixtures and Equipment. Tenant shall not cut or drill
         into, or secure any trade fixtures, apparatus or equipment of any kind
         to any part of the Leased Premises without first obtaining the written
         consent of Landlord. All furnishings, trade fixtures, equipment, and
         machines installed by Tenant in the Leased Premises shall be new or
         completely reconditioned and remain the property of Tenant subject to
         Landlord's security interest as defined at Paragraph 4.1 above and 
         shall be removable at the expiration or earlier termination of this
         Lease or any renewal or extension thereof, provided Tenant shall not at
         such time be in default under any covenant or agreement contained in
         this Lease; and provided further, that in the event of such removal,
         Tenant shall promptly restore the Leased Premises to their original
         order and condition. Any such equipment not removed at or prior to such
         termination shall be and become the property of Landlord.

5.4      Initial Installation and Improvements by Tenant. Tenant shall submit to
         Landlord complete architectural, electrical and mechanical plans and
         specifications covering all work which Tenant proposes to do in the
         Leased Premises including the fixturing thereof, whether such work is
         to be done by Tenant or others. Such plans and specifications shall be
         prepared in such detail as Landlord may require, and Tenant agrees not
         to commence work upon any portion of the Leased Premises until Landlord
         has approved such plans and specifications in writing. Landlord agrees
         to act with reasonable promptness with respect to such plans and
         specifications. Any changes in said plans or specifications must be
         similarly approved by Landlord.

         All of Tenant's work and installations shall be done in a first class,
         workmanlike manner and in compliance with all laws, rules, regulations
         and orders of all governmental


                                      - 6 -
<PAGE>   11
         authorities having jurisdiction thereof, and, in the performance of
         Tenant's work, Tenant shall engage and employ only such labor as will
         not cause any conflict or controversy with any labor organization
         representing trades performing work for Landlord or others in the
         Leased Premises.

         Tenant shall, at Tenant's own expense, promptly remove from the Leased
         Premises all trash and debris which may accumulate in connection with
         Tenant's work in the Leased Premises.

         Landlord shall have no liability or responsibility for loss of, or any
         damage to fixtures, equipment or other property of Tenant so installed
         or placed on the Leased Premises.

5.5      Mechanic's Lien. If Tenant makes any alterations or improvements in the
         Leased Premises, Tenant must pay for them when made. Nothing in the
         Lease shall be construed to authorize Tenant or any person dealing with
         or under Tenant, to charge the rents of the Leased Premises, or the
         property of which the Leased Premises form a part, or the interest of
         Landlord in the estate of the Leased Premises, or any person under and
         through whom Landlord has acquired its interest in the estate of the
         Leased Premises, with a mechanic's lien or encumbrance of any kind, and
         under no circumstances shall Tenant be construed to be the agent,
         employee or representative of Landlord in the making of such
         alterations or improvements to the Leased Premises, but, on the
         contrary, the right or power to charge any lien, claim or encumbrance
         of any kind against Landlord's rents or the Leased Premises or said
         land is denied. So long as the laws of this state shall provide for the
         filing of a statutory bond to eliminate the attachment of mechanic's or
         materialmen's liens to real estate, Tenant shall require that its
         contractor or itself shall take such steps as are provided by law for
         the filing of said statutory bond prior to the initiation of any
         construction. If a mechanic's or materialmen's lien is threatened by
         any contractor or supplier, or in the event of the filing of a notice
         of any such lien, Tenant will promptly take steps immediately to have
         any such lien removed. If the lien is not removed within ten (10) days
         from the date of written notice from Landlord, Landlord shall have the
         right at Landlord's option to cause the lien to be discharged by record
         of payment, deposit, bond or order of a court of competent jurisdiction
         or otherwise, to pay any portion thereof and of the amounts so paid,
         including attorney's fees and expenses connected therewith and interest
         at the rate of eighteen percent (18%) per annum on any sums paid or
         advanced, shall be deemed to be additional rent due from Tenant to
         Landlord and shall be paid to Landlord immediately upon rendition to
         Tenant of a bill therefor. Tenant will indemnify and save harmless
         Landlord from and against all loss, claims, damages, costs or expenses
         suffered by Landlord by reason of any repairs, installations or
         improvement, made by Tenant.

         Except as may be expressly provided in this Lease, nothing in this
         Article 5 shall be construed to permit Tenant to place any materials 
         upon the Leased Premises or cause any labor or construction, or to make
         any alterations, additions, replacements or substantial repairs, in or
         about the Leased Premises. Landlord shall have the further right any
         time,


                                      - 7 -
<PAGE>   12
         and from time to time, to post and maintain on the Leased Premises such
         notices as Landlord deems necessary to protect the Leased Premises and
         Landlord, from all liens of any nature whatsoever.

         No mechanic's or materialmen's liens or mortgages, deeds of trust, or
         other liens of any character whatsoever created or suffered by Tenant
         shall in any way, or to any extent, affect the interest or rights of
         Landlord in any buildings or other improvements on the Leased Premises,
         or attach to or affect Landlord's title to or rights in the Leased
         Premises.

ARTICLE 6. USE OF LEASED PREMISES

6.1      Tenant's Use of Leased Premises. Tenant shall use and occupy the Leased
         Premises only for conducting its steel fabrication and erection
         business and related operations and for no other purpose without
         Landlord's prior written consent.

6.2      Conduct of Tenant's Operations. At all times throughout the Lease term,
         Tenant shall:

         6.2.1    Comply with any and all requirements of any of the constituted
                  public authorities, and with the terms of any state or federal
                  statue or local ordinance or regulation applicable to Tenant
                  or its use, safety, cleanliness or occupation of the Leased
                  Premises, and save Landlord harmless from penalties, fines,
                  costs, expenses or damages resulting from failure to do so.

         6.2.2    Give to Landlord prompt written notice of any accident, fire
                  or damage occurring on or to the Leased Premises.

         6.2.3    Conduct its business in the Leased Premises in all respects in
                  a dignified manner and in accordance with high standards of
                  store operation.

         6.2.4    Comply with all reasonable rules and regulations of Landlord
                  in effect at the time of the execution of this Lease or at any
                  time or times, and from time to time, promulgated by Landlord,
                  which Landlord in its sole discretion shall deem necessary in
                  connection with the demised Leased Premises, the building of
                  which the demised Leased Premises are a part or the Shopping
                  Center, including both the operation of Tenant's business
                  during certain minimum days and hours and the installation of
                  such fire extinguishers, water buckets and other safety
                  equipment as Landlord may reasonably require.

6.3      Rights Reserved by Landlord.

         6.3.1    Easements. Landlord expressly reserves all rights in and with
                  respect to the land hereby leased not inconsistent with
                  Tenant's use of the Leased Premises as provided in the Lease,
                  including (without in anyway limiting the generality of the


                                      - 8 -
<PAGE>   13
                  foregoing) the rights of Landlord to enter upon the Leased
                  Premises and give easements to others for the purpose of
                  installing, using, maintaining, renewing and replacing such
                  overhead or underground water, gas, sewer and other pipe
                  lines, and telephone, electric, and power lines, cables and
                  conduits as Landlord may deem desirable in connection with the
                  development or use of any other property in the neighborhood
                  of the land hereby leased, whether owned by Landlord or not,
                  all of which pipelines, lines and conduits shall be buried to
                  a sufficient depth or raised to a sufficient height so as not
                  to interfere with the use or stability of the building or any
                  other improvements on the land hereby leased.

         6.3.2    Inspection. Landlord reserves the right to, at all reasonable
                  times, by itself or its duly authorized agents, employees and
                  contractors to go upon and inspect the demised Leased Premises
                  and every part thereof, to enforce or carry out the provisions
                  of this Lease, to perform any defaulted obligation of Tenant
                  or for any other proper purposes.

         6.3.3    Presentation for Sale or Lease. Landlord hereby reserves the
                  right during usual business hours to enter the Leased Premises
                  and to exhibit the same for purposes of sale, lease or
                  mortgage, and during the last six (6) months of the term of
                  this Lease, to exhibit the Leased Premises to any prospective
                  Tenant, and to display a "For Sale" sign at any time, and also
                  after notice from either party of intention to terminate this
                  Lease, or at any time within six (6) months prior to the
                  expiration of the Lease, a "For Rent" sign, or both "For Sale"
                  and "For Rent" signs, and all said signs shall be placed upon
                  such part of the Leased Premises as Landlord shall require,
                  except on doors leading into the Leased Premises. Prospective
                  purchasers or tenants authorized by Landlord may inspect the
                  Leased Premises at reasonable hours at any time.

ARTICLE 7. LIABILITY INSURANCE AND INDEMNIFICATION

7.1      Insurance. During the term of this Lease, Tenant, at Tenant's expense,
         shall keep the building of which the Leased Premises are a part insured
         against loss or damage by fire and the hazards covered by extended
         coverage insurance in an amount equal to not less than the full
         insurable value of such building. The policy or policies therefor shall
         name Landlord as insured and shall be payable to Landlord. Tenant shall
         not commit or permit any acts in or about the Leased Premises which may
         in any way impair or invalidate such policy or policies of insurance
         for the building.

         Tenant shall be solely responsible for obtaining any fire or extended
         coverage insurance for personal property and improvements of Tenant and
         for all goods, commodities and materials stored by Tenant in or about
         the Leased Premises. Tenant agrees that if any property owned by it and
         located in the Leased Premises shall be damaged or destroyed, Landlord
         shall not have any liability to Tenant, nor to any insurer of Tenant,
         for or in respect of such damage or destruction, and Tenant shall
         require all policies of risk


                                      - 9 -

         insurance carried by it on its property in the Leased Premises to
         contain or be endorsed with a provision in and by which the insurer
         designated therein shall waive its right of subrogation against
         Landlord.

7.2      Operations of Tenant. All operations conducted by Tenant shall be at
         Tenant's sole risk. In addition, Tenant shall procure and keep in force
         at its own expense public liability insurance and comprehensive general
         liability insurance, including contractual liability insurance
         sufficient to cover all phases and aspects of the operation and conduct
         of its business, with minimum limits of $1,000,000 on account of bodily
         injuries to or death of one person, and $3,000,000 on account of bodily
         injuries to or death of more than one person as the result of any one
         accident or disaster, and $1,000,000 on account of damage to property.

7.3      Policy Requirements. All insurance policies required of Tenant in this
         Lease shall name as insured both Landlord and Tenant (and upon request,
         any other party named by Landlord) and shall contain an express waiver
         of any right of subrogation against Landlord and other named insureds
         designated by Landlord. All policies shall be in such companies as are
         authorized to write such coverage in Arizona, shall be acceptable to
         Landlord and/or its lender (which shall be named as an additional
         insured if requested in writing). Tenant will further deposit the
         policy or policies of such insurance or certificates thereof, with
         Landlord with evidence of payment of premium at all times commencing
         with the date of this Lease. Each policy shall provide against
         cancellation without thirty (30) days prior written notice to the named
         insureds.

7.4      Failure to Procure Insurance. In the event Tenant shall fail to procure
         insurance required under this Article 7 and fails to maintain such
         insurance in force continuously during the term of this Lease, Landlord
         shall be entitled to procure such insurance, and Tenant shall
         immediately reimburse Landlord for such premium expense.

7.5      Indemnification and Waiver of Claims. Tenant indemnifies Landlord and
         waives claims as follows:

         7.5.1    Indemnification. Tenant will indemnify Landlord and save it
                  harmless from and against any and all claims, actions,
                  damages, liability and expense in connection with loss of
                  life, personal injury and/or damage to property occurring in
                  or about, or arising from or out of, the Leased Premises and
                  adjacent sidewalks and loading platforms or areas or
                  occasioned wholly or in part by any act or omission of Tenant,
                  its agents, contractors, customers or employees. Additionally,
                  Tenant agrees to indemnify and hold harmless Landlord with
                  respect to any claim, cause of action or proceeding, in law or
                  in equity, civil, criminal or administrative, asserted or
                  brought by any person, firm or corporation. Tenant agrees to
                  defend at its own cost and expense any lawsuit or proceeding
                  referred to above and to reimburse Landlord for any reasonable
                  expenses or damages, including reasonable attorney's fees,
                  incurred in any such proceeding, lawsuit,


                                     - 10 -
<PAGE>   15
                  administrative action, or investigation commenced in whole or
                  in part by reason of said exclusive clause.

         7.5.2    Waiver of Claims. Landlord and Landlord's agents, employees
                  and contractors shall not be liable for, and Tenant hereby
                  releases all claims for, damage to person and property
                  sustained by Tenant or any person claiming through Tenant
                  resulting from any theft, fire, accident, occurrence or
                  condition in or upon the Leased Premises or building of which
                  they shall be a part.

                  In the event the Leased Premises or its contents are damaged
                  or destroyed by fire or other insured casualty, the rights, if
                  any, of either party hereto against the other with respect to
                  such damage or destruction are waived; and all policies of
                  fire and/or extended coverage or other insurance covering the
                  Leased Premises or its contents shall contain a clause or
                  endorsement providing in substance that the insurance shall
                  not be prejudiced if the insureds have waived the right of
                  recovery from any person or persons prior to the date and time
                  of loss or damage, if any.

         7.5.3    Notice of Claims or Suits. Tenant agrees to promptly notify
                  Landlord of any claim, action, proceeding or suit instituted
                  or threatened against Landlord. In the event Landlord is made
                  a party to any action for damages which Tenant has herewith
                  indemnified Landlord against, then Tenant shall pay all costs
                  and shall provide effective counsel in such litigation or
                  shall pay, at Landlord's option, the attorney fees and costs
                  incurred in connection with said litigation by Landlord.

ARTICLE 8. LOSS, DESTRUCTION OR TAKING OF LEASED PREMISES

8.1      Fire or Other Casualty. Tenant shall give to Landlord prompt written
         notice of any accident, fire or damage occurring on or to the Leased
         Premises and shall fully cooperate with Landlord in filing all
         necessary proofs of claim with insurance companies. The proceeds of
         such insurance applicable to the Leased Premises shall be paid to
         Landlord and Landlord shall rebuild, repair or restore the Leased
         Premises to the condition at the time immediately preceding the loss or
         damage; provided, however, that Landlord may elect to retain such
         insurance proceeds and shall not be required to rebuild, repair or
         restore the Leased Premises, and this Lease shall be terminated, if
         such damage or destruction occurs within the last year of the term of
         this Lease, or if more than one-third (1/3) of the Leased Premises is
         so damaged or destroyed. In the event of total destruction of the
         Leased Premises, the rent shall abate during the period of rebuilding,
         repair or restoration by Landlord, or, in the event of partial
         destruction of the Leased Premises, the rent shall abate pro rata
         during the period of rebuilding, repair or restoration by Lessor.

8.2      Condemnation. If title to all or any portion of the Leased Premises be
         taken by a public or quasi-public authority under any statute or by
         right of eminent domain of any


                                     - 11 -
<PAGE>   16
         governmental body, whether such loss or damage results from
         condemnation of part or all of the Leased Premises, Tenant shall not be
         entitled to participate or receive any part of the damages or award
         except where said award shall provide for moving or other reimbursable
         expenses for Tenant under applicable statute, in which event the latter
         sum shall be received by Tenant, and except that portion of any award
         allocated to the taking of Tenant's trade fixtures, equipment and
         personal property, or to a loss of business by Tenant. None of the
         awards or payments to Landlord shall be subject to any diminution or
         apportionment on behalf of Tenant or otherwise.

         If any power of eminent domain is exercised during the term of this
         Lease, such exercise shall not void or impair this Lease unless the
         amount of the Leased Premises so taken is such as to substantially and
         materially impair the usefulness of the Leased Premises for the purpose
         of which they are hereby demised, in which event either party may
         cancel this Lease by notice to the other within sixty (60) days after
         possession is taken, and the rental herein provided shall abate as of
         the date possession is taken by the condemning authority.

         If a portion of the Leased Premises shall be taken as herein provided
         for public improvements or otherwise under the exercise of the right of
         eminent domain and the Leased Premises shall continue to be reasonably
         suitable for the use which is hereby authorized, then the rental herein
         provided shall be reduced from the date of such taking in direct
         proportion to the reduction in usefulness of the Leased Premises.

ARTICLE 9. ASSIGNMENT, SUBLETTING, MORTGAGING AND SUBORDINATION

9.1      Assignment and Subletting by Tenant. Tenant shall not convey, assign,
         mortgage, pledge or encumber this Lease, in whole or in part, nor
         sublet the whole or any part of the Leased Premises, or permit the use
         of the whole or any part of the Leased Premises by any licensee or
         concessionaire, without first obtaining the written consent of
         Landlord. This prohibition shall be construed to include a prohibition
         against any assignment or subletting by operation of law, assignment
         for the benefit of creditors, voluntary or involuntary bankruptcy or
         reorganization, or otherwise, without the prior written consent of
         Landlord. Any assignment or sublease without Landlord's written consent
         is in violation of this Lease and a default hereunder and, at the
         option of Landlord, shall be voidable.

         Landlord's consent or refusal to consent to any such subletting may be
         based upon, but shall not be limited to, factors pertaining to (a) the
         acceptability of the proposed subtenant to the Leased Premises, and (b)
         the financial statement, credit and ability of any proposed subtenant
         to meet the obligations, terms and conditions of this Lease.

         The acceptance of any rental payments by Landlord from any alleged
         assignee shall not constitute approval of the assignment of this Lease
         by the Landlord, and the consent by


                                     - 12 -
<PAGE>   17
         Landlord to one assignment or subletting of the Leased Premises shall
         not constitute a waiver of Landlord's rights hereunder.

         Tenant shall pay to Landlord the sum of $500.00 as a Transfer Fee for
         such written consent. In the event of any such assignment, subletting,
         licensing or granting of a concession, made with the written consent of
         the Landlord as aforesaid, Tenant will nevertheless remain liable for
         the performance of all the terms, conditions, and covenants of this
         Lease. Any permitted assignment or subletting shall be by agreement in
         form and content acceptable to Landlord, and shall specify and require
         that each subtenant or assignee acquiring this Lease by acceptance of
         any sublease, assignment or transfer shall assume, be bound by, and be
         obligated to perform the terms and conditions of its sublessor and
         assignor under this Lease. A condition of such assignment or subletting
         is the agreement of the parties that Landlord shall receive the full
         and complete rental payment of subtenant or assignee, though such
         payments may be in excess of the original rental between Landlord and
         Tenant. It is the intent and understanding of the parties to this
         Agreement that Tenant shall not receive any monetary benefit in excess
         of the actual rental obligation of Tenant as agreed between the
         original Tenant and Landlord through a sublease or assignment to a
         third party. In the event of default of Tenant, Landlord, at Landlord's
         sole option, may succeed to the position of Tenant as to any subtenant
         or licensee of Tenant.

9.2      Assignment and Mortgaging by Landlord. The term "Landlord" as used in
         this Lease means the owner of the Leased Premises. So long as all sums
         held on Tenant's behalf in trust or escrow by Landlord are paid over to
         any purchaser of said Leased Premises, Landlord shall be and is hereby
         relieved of all covenants and obligations of Landlord hereunder after
         the date of sale of the Leased Premises, and it shall be construed
         without further agreement between the parties that the purchaser has
         assumed and agreed to carry out any and all covenants and obligations
         of Landlord hereunder from the date of such sale.

9.3      Subordination. This Lease shall, upon request by Landlord, be subject
         and subordinate to any and all leases, mortgages or deeds of trust
         hereinafter placed upon the Leased Premises, or any part thereof, and
         to all future modifications, consolidations, replacements, extensions
         and renewals of, and all amendments and supplements to said leases,
         mortgages or deeds of trust. Notwithstanding such subordination as
         aforesaid, this Lease, except as otherwise hereinafter provided, shall
         not terminate or be divested by foreclosure or other default
         proceedings under said leases, mortgages, deeds of trust, or
         obligations secured thereby, and Tenant shall attorn to and recognize
         the landlord, mortgagee, trustee, beneficiary or the purchaser at the
         foreclosure sale in the event of such foreclosure or other default
         proceeding, as Tenant's Landlord hereunder for the balance of the term
         of this Lease, subject to all of the terms and provisions hereof.

9.4      Offset Statement. Tenant agrees to execute, acknowledge and deliver any
         and all documents required to effectuate the provisions of this Article
         9, and within ten (10) days


                                     - 13 -
<PAGE>   18
         after request therefor by Landlord or in the event that upon any sale,
         assignment, lease or hypothecation of the Leased Premises and/or the
         land thereunder by Landlord, an offset statement shall be required by
         Tenant, Tenant agrees to deliver in recordable form a certificate (if
         such be the case) that this Lease is in full force and effect and there
         are no defenses or offsets thereto, or stating those claimed by Tenant,
         and the dates to which rental or other sums have been paid in advance,
         it being intended that any such statement delivered pursuant to this
         Paragraph 9.4 may be relied upon by any prospective purchaser,
         mortgagee, assignee or beneficiary. Tenant shall also deliver to any
         prospective institutional lender of Landlord, upon Landlord's
         reasonable request therefor, from time to time, Tenant's latest
         financial statements and such specific subordination agreement on
         Lender's form as may be required by Lender. Tenant acknowledges and
         agrees that the promises to issue statements pursuant to this Paragraph
         9.4 are a material consideration inducing Landlord to enter into this
         Lease, and that the breach of such promise shall be deemed a material
         breach of this Lease, and shall constitute a default hereunder.

ARTICLE 10. DEFAULT AND REMEDIES FOR DEFAULT

10.1     Events of Default. The occurrence of any of the following constitute an
         event of default hereunder:

         10.1.1   Tenant Bankruptcy/Insolvency. The filing of a petition by or
                  against Tenant for adjudication as a bankrupt or insolvent, or
                  for its reorganization or for the appointment of a receiver or
                  trustee of Tenant's property; an assignment by Tenant for the
                  benefit of creditors; or the taking of possession of the
                  property of Tenant by any governmental officer or agency
                  pursuant to statutory authority for the dissolution or
                  liquidation of Tenant.

         10.1.2   Delinquency in Payment. Failure of Tenant to pay when due any
                  installment of rent hereunder or any other sum herein required
                  to be paid by Tenant, and the continuance of such nonpayment
                  for five (5) days after written notice from Landlord.

         10.1.3   Abandonment. Abandonment of the Leased Premises by Tenant.

         10.1.4   Failure to Perform Covenants. Tenant's failure to perform any
                  other covenant or condition of this Lease within twenty (20)
                  days after written notice and demand, unless the failure is of
                  such a character as to require more than twenty (20) days to
                  cure, in which event Tenant's failure to proceed diligently to
                  cure such failure shall constitute an event of default.

10.2     Remedies of Landlord for Default by Tenant. Upon the occurrence of an
         event of default, Landlord shall have the right, then or at any time
         thereafter, and while such


                                     - 14 -
<PAGE>   19
         event of default shall continue, and in addition to and not in lieu of
         any other remedies, relief or rights available to Landlord at law or
         equity or contained in this Lease, to do any of the following:

         10.2.1   Landlord Cure. Landlord by itself or its authorized agents may
                  cure the default and charge Tenant for the costs of such cure,
                  which charge shall be due and payable as rental under this
                  Lease immediately upon written notice to Tenant.

         10.2.2   Distrain. Landlord may distrain for rent due.

         10.2.3   Exercise General Lien. Landlord may exercise its general lien
                  on the leasehold estate and all property in the Leased
                  Premises.

         10.2.4   Right of Re-Entry. Landlord shall have the right to re-enter
                  the Leased Premises to assume and take possession of the whole
                  or any part thereof, and to remove all persons or personal
                  property by direct or summary action, or in a different type
                  of suit or proceeding, by force or otherwise, without being
                  deemed guilty of trespass or other actionable wrong by reason
                  thereof, and without being liable for the damages therefor or
                  in connection therewith, and, after demand made therefor,
                  Tenant or anyone in possession claiming under Tenant shall be
                  deemed guilty of unlawful detainer and subject to such summary
                  or other action as may be provided by law. Additionally,
                  Landlord may relet the Leased Premises as the agent for and in
                  the name of the Tenant, at any rental readily acceptable,
                  applying the proceeds first to the payment of such rent as the
                  same comes due, and toward the fulfillment of the other
                  covenants and agreements of Tenant herein contained, and the
                  balance, if any, shall be paid to Tenantl; and the Tenant
                  hereby agrees that if Landlord shall recover or take
                  possession of said Leased Premises as aforesaid and be unable
                  to relet and rent the same so as to realize a sum equal to the
                  rent hereby reserved, Tenant shall pay to Landlord any loss or
                  difference of rent for the remainder of the term.

         10.2.5   Termination of Lease. Landlord, irrespective of the date on
                  which its right of re-entry shall have accrued or be
                  exercised, shall have the right, whether for rent or
                  possession or otherwise, to forfeit this Lease and terminate
                  the state of tenancy hereby created. This right to terminate
                  is exercisable by a written notice to Tenant, which written
                  notice may be part of a notice of default previously delivered
                  to Tenant, and, as such, may be conditioned upon Tenant's
                  failure to cure the default and the event of default. The
                  termination may be made effective as of the event of default
                  or thereafter, and, if not otherwise specified, will be deemed
                  to be effective immediately. Upon such termination and
                  forfeiture, Landlord


                                     - 15 -
<PAGE>   20
                  shall be entitled to and may take immediate possession of the
                  Leased Premises, any other notice or demand being hereby
                  waived. Such termination does not, however, release Tenant
                  from liability for rentals then overdue or remaining under the
                  Lease but shall operate to accelerate the entire balance of
                  the term rental, which shall become immediately due and
                  payable by Tenant, along with all overdue rentals and charges.

10.3     Non-Waiver of Remedies. It is expressly agreed that neither the taking
         of possession of the Leased Premises nor the institution of any
         proceedings by way of unlawful detainer, ejectment, quiet title, or
         otherwise, to secure possession of the Leased Premises, nor the
         re-entry by Landlord with or without the institution of such
         proceedings, nor the rerenting or subletting of the Leased Premises,
         shall operate to terminate this Lease in whole or in part, nor of
         itself constitute an exercise of Landlord's option to do so, but only
         by the giving of the written notice specifically specifying termination
         shall such termination be effected.

         In the event Tenant breaches this Lease, or any covenant, term or
         condition hereunder, and abandons the Leased Premises, this Lease shall
         continue in force and effect for so long as the Landlord does not
         terminate Tenant's right to possession, and Landlord may enforce all
         rights and remedies of Landlord including, without limitation, the
         right to recover rental as it becomes due hereunder. Acts of
         maintenance or preservation or efforts to relet the Leased Premises, or
         the appointment of a receiver upon the initiation of the Landlord to
         protect the Landlord's interest under this Lease shall not constitute a
         termination of Tenant's right to possession.

         Waiver by Landlord of any default, breach or failure of Tenant under
         this Lease shall not be construed as a wavier of any subsequent or
         different default, breach or failure. In case of a breach by Tenant of
         any of the covenants or undertakings of Tenant, Landlord nevertheless
         may accept from Tenant any payments hereunder without in any way
         waiving Landlord's right to exercise the remedies hereinbefore provided
         for by reason of any other breach or lapse which was in existence at
         the time such payment or payments were accepted by Landlord.

         It is expressly understood that the enumeration herein of express
         rights, options and privileges shall not limit Landlord nor deprive
         Landlord of any other remedy or action or cause of action by reason of
         any default of Tenant, including the right to recover from Tenant any
         deficiency upon re-renting.

         The specific remedies to which Landlord may resort under the terms of
         this Lease are cumulative and are not intended to be exclusive of any
         other remedies or means of redress to which they may be lawfully
         entitled in case of any breach or threatened breach by either of them
         or of any provisions of this Lease.

                                      LEASE


                  THIS LEASE is entered into as of the 1st day of March, 1997,
by and between 19th AVENUE/BUCHANAN LIMITED PARTNERSHIP, an Arizona limited
partnership ("Landlord"), and B & K STEEL FABRICATIONS, INC., an Arizona
corporation ("Tenant").

ARTICLE 1.        LEASED PREMISES

1.1      Leased Premises. Landlord leases to Tenant the land and improvements
         located at 619 N. Cooper Road, Gilbert, Arizona, as more particularly
         described on Exhibit "A" ("Leased Premises").

ARTICLE 2. TERM

2.1      Term of Lease. The term of this Lease shall be twenty (20) years
         commencing on March 1, 1997 and ending on February 28, 2017.

2.2      Quiet Enjoyment. Landlord agrees that so long as the rent is being paid
         in the manner and at the time prescribed and the covenants and
         obligations of Tenant are being all and singularly kept, fulfilled and
         performed, Tenant shall lawfully and peaceably have, hold, possess, use
         and occupy and enjoy the Leased Premises so long as this Lease remains
         in force without hindrance, disturbance or molestation from Landlord,
         subject to the specific provisions of this Lease.

2.3      Surrender of Leased Premises. Upon any termination of this Lease,
         whether by lapse of time, cancellation pursuant to an election provided
         for herein, forfeiture, or otherwise, Tenant shall immediately
         surrender possession of the Leased Premises and all buildings and
         improvements on the same to Landlord in good and tenantable repair,
         reasonable wear and damage from fire or other casualty or peril
         excepted, and shall surrender all keys for the Leased Premises to
         Landlord at the place then fixed for the payment of rent and shall
         inform Landlord of all combinations of locks, safes and vaults, if any,
         in the Leased Premises.

         At any time during the ten (10) days before the termination date of
         this Lease, Tenant, if not in default hereunder at such time, shall
         have the right to remove, and at the end of the term, if directed to do
         so by Landlord, shall remove from the Leased Premises all furniture,
         furnishings, signs, and equipment then installed or in place in, on or
         about the Leased Premises; provided, however, Tenant shall, and it
         covenants and agrees to, make all repairs to the Leased Premises
         required because of such removal. If any of such property shall remain
         on the Leased Premises after the end of the term hereof, such property
         shall be and become the property of Landlord without any claim therein
         of Tenant. Landlord may direct Tenant to remove such property, in which
         case Tenant


                                      - 1 -

         agrees to do so, and to reimburse Landlord for any expense of removal
         in the event Tenant shall fail to remove such property if and when
         directed.

         Leased Premises, including all fixtures and tenant improvements, in a
         neat and broom clean condition, and Tenant shall repair any holes or
         openings made by Tenant in the walls, roof or floor of the building,
         remove any protuberance and perform any maintenance or repairs required
         of Tenant by this Lease. If directed to do so by Landlord, Tenant shall
         also remove any improvements, additions or alterations made to the
         Leased Premises by Tenant even though such improvements by the terms of
         this Lease become a part of the Leased Premises.

2.4      Holding Over. If Tenant, upon expiration or termination of this Lease,
         either by lapse of time or otherwise, remains in possession of the
         Leased Premises with Landlord's written consent but without a new lease
         reduced to writing and duly executed, Tenant shall be deemed to be
         occupying the Leased Premises as a tenant at will, subject to all the
         covenants, conditions and agreements of this Lease. If Tenant remains
         in possession without Landlord's written consent, Tenant shall be
         deemed to be in wrongful holdover and shall be subject to all the
         rights and remedies provided to Landlord under this Lease and the
         applicable laws, including any forcible entry and detainer actions or
         other eviction processes.

2.5      Abandonment. If Tenant, prior to the expiration or termination of this
         Lease by lapse of time or otherwise, relinquishes possession of the
         Leased Premises without Landlord's written consent, such relinquishment
         shall be deemed to be an abandonment of the Leased Premises and an
         event of default under this Lease.

ARTICLE 3. RENTALS AND OTHER TENANT CONTRIBUTIONS

3.1      Minimum Rent. Tenant shall pay to Landlord minimum annual rent in the
         amount of Three Hundred Forty Thousand Dollars ($340,000.00) per year,
         payable in advance in equal monthly installments of Twenty-eight
         Thousand Three Hundred Thirty-three Dollars ($28,333.00) ("Minimum
         Rent") on the first day of each calendar month, without prior demand
         therefor.

3.2      Adjustment of Minimum Rent. The minimum annual rent is subject to
         adjustment every five (5) years during the term of this Lease, with
         each adjustment to commence on March 1 of the year of adjustment
         ("Adjusted Minimum Rent"). The Adjusted Minimum Rent shall be effective
         as of March 1, 2002, March 1, 2007, and March 1, 2012 during the term

<PAGE>   4
         3.2.1    Computation of Adjusted Minimum Rent. The Adjusted Minimum
                  Rent shall be computed based on the increase in the Consumer
                  Price Index - U.S. City average - All Urban Consumers
                  ("Index") as published by the United States Department of
                  Labor's Bureau of Labor Statistics over the base period index.
                  The base period index shall be the index for the calendar
                  month of December 1996. The base period index shall be
                  compared with the Index for the same calendar month for each
                  subsequent December in the year immediately preceding the
                  effective date of each adjustment (comparison month). If the
                  Index for any comparison month is higher than the base period
                  index, then the Minimum Rent for the next succeeding
                  adjustment period shall be increased by the identical
                  percentage commencing with the next succeeding March 1. In no
                  event shall the Minimum Rent be less than that the amount paid
                  immediately prior to any such adjustment.

         3.2.2    Use of Different Index. If the Bureau discontinues the
                  publication of the Index, or publishes it less frequently, or
                  alters it in any manner, then Landlord shall adopt a
                  substitute index or substitute procedure which reasonably
                  reflects and monitors consumer prices.

3.3      Payment of Rent. Tenant shall, without prior notice or demand and
         without any setoff or deduction whatsoever, pay all rentals and other
         charges and render all statements herein prescribed at the Landlord's
         address or to such other person or corporation, and at such other
         place, as shall be designated by Landlord in writing at least ten (10)
         days prior to the next ensuing rental payment date.

3.4      Taxes.

         3.4.1    Rent Tax. Tenant shall pay as additional rent, any privilege
                  tax, sales tax, gross proceeds tax, rent tax or like tax (but
                  not including income tax), now or hereafter levied, assessed
                  or imposed by any federal, state, county or municipal
                  governmental authority, or any subdivision thereof, upon any
                  rent or other payments require to be paid under this Lease.

         3.4.2    Personal Property Tax. Tenant shall pay before delinquent, as
                  additional rent, all personal property taxes and assessments
                  levied or assessed by any governmental authority against any
                  personal property or fixtures of Tenant in, on or about the
                  Leased Premises.

         3.4.3    Real Property Tax. Tenant shall pay before delinquent,
                  exhibiting receipts to Landlord on demand, all real property
                  taxes and assessments levied or assessed against the Leased
                  Premises and improvements thereon, all water charges or
                  assessments levied in connection with any improvements or
                  irrigation projects, or district or other taxes, assessments
                  or governmental charges of any kind levied or assessed against
                  the Leased Premises. Tenant shall have the right, in good
                  faith


                                      - 3 -
<PAGE>   5
          and at its sole and own cost and expense and in its own name or in the
          name of Landlord, to protest or contest or seek to have reviewed,
          reduced, equalized or abated any tax or assessment by legal
          proceedings in such manner as it may deem advisable. No protest,
          contest or other action, however, shall be maintained by Tenant after
          the time limited for the payment without penalty or interest of the
          tax or assessment unless Tenant shall have first paid the amount of
          such tax or assessment under protest or shall have procured a stay of
          proceedings to enforce the collection thereof, and shall have also
          provided for the payment thereof, together with all penalties,
          interest, cost and expenses, by the deposit of a bond in form approved
          by Landlord if required by law to accomplish such stay.

3.5      Interest. Tenant covenants and agrees that all sums to be paid under
         this Lease, if not paid when due, shall bear interest on the unpaid
         portion thereof at the rate of eighteen (18%) per annum from the date
         when due. If Landlord shall pay any monies, or incur any expenses in
         correction of any violation of any covenant of Tenant herein set forth,
         the amounts so paid, or, incurred shall, at Landlord's option and on
         notice to Tenant, be considered additional rentals payable by Tenant
         with the first installment of rental thereafter to become due and
         payable, and may be collected or enforced as by law provided with
         respect to rentals.

3.6      Utilities Consumed on Leased Premises. In addition to all rentals
         herein specified, Tenant shall be responsible for and shall pay for all
         utilities used or consumed in or upon the Leased Premises, and all
         sewer charges, as and when the charges therefor shall become due and
         payable, throughout the term of this Lease. Tenant shall make all
         appropriate applications to the local utility companies and pay all
         required deposits for meters and service for all utilities.

         In the event any utility or utility service (such as water or sewage
         disposal) are furnished to Tenant for which a lien could be filed
         against the Leased Premises or any portion thereof, Tenant shall, at
         Landlord's request, pay the cost thereof to Landlord as and when the
         charges therefor become due and payable; otherwise, Tenant shall
         deliver original receipted bills to Landlord within thirty (30) days
         after the same are due and payable without interest or penalty.

         In no event shall Landlord be liable for any interruption or failure in
         the supply of any utilities to the Leased Premises.

ARTICLE 4. SECURITY

4.1      Landlord's Lien. Landlord shall have a general lien on the leasehold
         estate hereby created and on all property kept or used on the Leased
         Premises, whether such property is exempt from execution or not, to
         secure payment of any and all monies then due or thereafter becoming
         due to Landlord under the terms and conditions of this Lease, and to


                                      - 4 -
<PAGE>   6
         secure the prompt performance and fulfillment by Tenant of each and
         every one of said terms and conditions. The lien as provided for in
         this Paragraph 4.1 attaches as of the date of execution hereof and
         shall remain in full force and effect unless expressly waived by
         Landlord in writing.

4.2      Security in Addition to Other Remedies. The security given Landlord in
         this Article 10 shall not limit, replace or obviate the remedies of
         Landlord upon a default by Tenant as described in Article below,
         including the right of Landlord to re-enter the Leased Premises,
         distrain for rent or pursue its general lien upon Tenant's property in
         the Leased Premises described in Paragraph 4.1 above.

ARTICLE 5. CONSTRUCTION, ALTERATIONS, MAINTENANCE AND REPAIRS

5.1      Tenant's Duty to Repair. Landlord shall not be called upon to make any
         improvements or repairs of any kind upon the Leased Premises and
         appurtenances unless such repairs are necessitated by the misuse or
         negligence of Landlord. Tenant shall keep and maintain in good order,
         condition and repair (including any such replacement, periodic
         painting, and restoration as is required for that purpose) the Leased
         Premises and every part thereof and any and all appurtenances hereto
         located. Any of the foregoing repairs required to be made by reason of
         the negligence of Landlord shall be the responsibility of the Landlord
         notwithstanding the provisions above contained in this paragraph.

         If Tenant refuses or neglects to commence and to complete repairs or
         maintenance required herein promptly and adequately, Landlord may, but
         shall not be required to, make and complete said repairs, and Tenant
         shall pay the cost thereof to Landlord as additional rent upon demand.
         Except as provided in Paragraph 8.1 (Fire and Casualty damage) and 8.2
         (Condemnation), Landlord shall not be obligated to repair, replace,
         maintain or alter the Leased Premises, and Tenant waives all laws in
         contravention thereof. With regard to repairs, Tenant expressly waives
         any right pursuant to any law now existing or which may be effective
         during the term hereof, to make repairs at Landlord's expense.

5.2      Tenant's Alterations and Improvements to Leased Premises. Tenant shall
         not make or cause to be made any alterations, additions or improvements
         to the building, or make any changes to the exterior of the building
         without first obtaining Landlord's written approval and consent.

         Tenant shall present to the Landlord plans and specifications for such
         work at the time approval is sought. No addition, alteration, change or
         improvement shall be made which will weaken the structural strength,
         lessen the value of, or change the architectural appearance of any
         building or other construction.

         Landlord may condition its approval of any additions or alterations by
         Tenant on the requirement that Tenant or its contractor secure and bear
         the cost of a labor and materials


                                      - 5 -
<PAGE>   7
         payment bond for the amount of the proposed construction reflecting
         Landlord as an obligee.

         All building materials and fixtures installed by Tenant shall be new or
         completely reconditioned. All alterations, improvements, additions and
         fixtures made or installed by Tenant as aforesaid shall remain upon the
         Leased Premises at the expiration or earlier termination of this Lease
         and shall become the property of Landlord, unless Landlord shall, prior
         to the expiration or termination of this Lease, have given written
         notice to Tenant to remove the same, in which event Tenant shall remove
         the same and restore the Leased Premises to the same good order and
         condition in which it was at the commencement of this Lease. Should
         Tenant fail so to do, Landlord may do so, collecting, at Landlord's
         option, the cost and expense thereof from the Tenant as additional
         rent.

5.3      Furniture, Trade Fixtures and Equipment. Tenant shall not cut or drill
         into, or secure any trade fixtures, apparatus or equipment of any kind
         to any part of the Leased Premises without first obtaining the written
         consent of Landlord. All furnishings, trade fixtures, equipment, and
         machines installed by Tenant in the Leased Premises shall be new or
         completely reconditioned and remain the property of Tenant subject to
         Landlord's security interest as defined at Paragraph 4.1 above and
         shall be removable at the expiration or earlier termination of this
         Lease or any renewal or extension thereof, provided Tenant shall not at
         such time be in default under any covenant or agreement contained in
         this Lease; and provided further, that in the event of such removal,
         Tenant shall promptly restore the Leased Premises to their original
         order and condition. Any such equipment not removed at or prior to such
         termination shall be and become the property of Landlord.

5.4      Initial Installation and Improvements by Tenant. Tenant shall submit to
         Landlord complete architectural, electrical and mechanical plans and
         specifications covering all work which Tenant proposes to do in the
         Leased Premises including the fixturing thereof, whether such work is
         to be done by Tenant or others. Such plans and specifications shall be
         prepared in such detail as Landlord may require, and Tenant agrees not
         to commence work upon any portion of the Leased Premises until Landlord
         has approved such plans and specifications in writing. Landlord agrees
         to act with reasonable promptness with respect to such plans and
         specifications. Any changes in said plans or specifications must be
         similarly approved by Landlord.

         All of Tenant's work and installations shall be done in a first class,
         workmanlike manner and in compliance with all laws, rules, regulations
         and orders of all governmental authorities having jurisdiction thereof,
         and, in the performance of Tenant's work, Tenant shall engage and
         employ only such labor as will not cause any conflict or controversy
         with any labor organization representing trades performing work for
         Landlord or others in the Leased Premises.


                                      - 6 -
<PAGE>   8
         Tenant shall, at Tenant's own expense, promptly remove from the Leased
         Premises all trash and debris which may accumulate in connection with
         Tenant's work in the Leased Premises.

         Landlord shall have no liability or responsibility for loss of, or any
         damage to fixtures, equipment or other property of Tenant so installed
         or placed on the Leased Premises.

5.5      Mechanic's Lien. If Tenant makes any alterations or improvements in the
         Leased Premises, Tenant must pay for them when made. Nothing in the
         Lease shall be construed to authorize Tenant or any person dealing with
         or under Tenant, to charge the rents of the Leased Premises, or the
         property of which the Leased Premises form a part, or the interest of
         Landlord in the estate of the Leased Premises, or any person under and
         through whom Landlord has acquired its interest in the estate of the
         Leased Premises, with a mechanic's lien or encumbrance of any kind, and
         under no circumstances shall Tenant be construed to be the agent,
         employee or representative of Landlord in the making of such
         alterations or improvements to the Leased Premises, but, on the
         contrary, the right or power to charge any lien, claim or encumbrance
         of any kind against Landlord's rents or the Leased Premises or said
         land is denied. So long as the laws of this state shall provide for the
         filing of a statutory bond to eliminate the attachment of mechanic's or
         materialmen's liens to real estate, Tenant shall require that its
         contractor or itself shall take such steps as are provided by law for
         the filing of said statutory bond prior to the initiation of any
         construction. If a mechanic's or materialmen's lien is threatened by
         any contractor or supplier, or in the event of the filing of a notice
         of any such lien, Tenant will promptly take steps immediately to have
         any such lien removed. If the lien is not removed within ten (10) days
         from the date of written notice from Landlord, Landlord shall have the
         right at Landlord's option to cause the lien to be discharged by record
         of payment, deposit, bond or order of a court of competent jurisdiction
         or otherwise, to pay any portion thereof and of the amounts so paid,
         including attorney's fees and expenses connected therewith and interest
         at the rate of eighteen percent (18%) per annum on any sums paid or
         advanced, shall be deemed to be additional rent due from Tenant to
         Landlord and shall be paid to Landlord immediately upon rendition to
         Tenant of a bill therefor. Tenant will indemnify and save harmless
         Landlord from and against all loss, claims, damages, costs or expenses
         suffered by Landlord by reason of any repairs, installations or
         improvement, made by Tenant.

         Except as may be expressly provided in this Lease, nothing in this
         Article 5 shall be construed to permit Tenant to place any materials
         upon the Leased Premises or cause any labor or construction, or to make
         any alterations, additions, replacements or substantial repairs, in or
         about the Leased Premises. Landlord shall have the further right any
         time, and from time to time, to post and maintain on the Leased
         Premises such notices as Landlord deems necessary to protect the Leased
         Premises and Landlord, from all liens of any nature whatsoever.


                                      - 7 -
<PAGE>   9
         No mechanic's or materialmen's liens or mortgages, deeds of trust, or
         other liens of any character whatsoever created or suffered by Tenant
         shall in any way, or to any extent, affect the interest or rights of
         Landlord in any buildings or other improvements on the Leased Premises,
         or attach to or affect Landlord's title to or rights in the Leased
         Premises.

ARTICLE 6. USE OF LEASED PREMISES

6.1      Tenant's Use of Leased Premises. Tenant shall use and occupy the Leased
         Premises only for conducting its steel fabrication and erection
         business and related operations and for no other purpose without
         Landlord's prior written consent.

6.2      Conduct of Tenant's Operations. At all times throughout the Lease term,
         Tenant shall:

                  public authorities, and with the terms of any state or federal
                  statue or local ordinance or regulation applicable to Tenant
                  or its use, safety, cleanliness or occupation of the Leased
                  Premises, and save Landlord harmless from penalties, fines,
                  costs, expenses or damages resulting from failure to do so.

         6.2.2    Give to Landlord prompt written notice of any accident, fire
                  or damage occurring on or to the Leased Premises.

         6.2.3    Conduct its business in the Leased Premises in all respects in

                  (5)      Comply with all reasonable rules and regulations of

                           this Lease or at any time or times, and from time to
                           time, promulgated by Landlord, which Landlord in its
                           sole discretion shall deem necessary in connection
                           with the demised Leased Premises, the building of
                           which the demised Leased Premises are a part or the
                           Shopping Center, including both the operation of
                           Tenant's business during certain minimum days and
                           hours and the installation of such fire
                           extinguishers, water buckets and other safety
                           equipment as Landlord may reasonably require.

6.3      Rights Reserved by Landlord.

         6.3.1    Easements. Landlord expressly reserves all rights in and with
                  respect to the land hereby leased not inconsistent with
                  Tenant's use of the Leased Premises as provided in the Lease,
                  including (without in anyway limiting the generality of the
                  foregoing) the rights of Landlord to enter upon the Leased
                  Premises and give easements to others for the purpose of
                  installing, using, maintaining, renewing and replacing such
                  overhead or underground water, gas, sewer and other pipe
                  lines,


                                      - 8 -
<PAGE>   10
                  and telephone, electric, and power lines, cables and conduits
                  as Landlord may deem desirable in connection with the
                  development or use of any other property in the neighborhood
                  of the land hereby leased, whether owned by Landlord or not,
                  all of which pipelines, lines and conduits shall be buried to
                  a sufficient depth or raised to a sufficient height so as not
                  to interfere with the use or stability of the building or any
                  other improvements on the land hereby leased.

         6.3.2    Inspection. Landlord reserves the right to, at all reasonable
                  times, by itself or its duly authorized agents, employees and
                  contractors to go upon and inspect the demised Leased Premises
                  and every part thereof, to enforce or carry out the provisions
                  of this Lease, to perform any defaulted obligation of Tenant
                  or for any other proper purposes.

         6.3.3    Presentation for Sale or Lease. Landlord hereby reserves the
                  right during usual business hours to enter the Leased Premises
                  and to exhibit the same for purposes of sale, lease or
                  mortgage, and during the last six (6) months of the term of
                  this Lease, to exhibit the Leased Premises to any prospective
                  Tenant, and to display a "For Sale" sign at any time, and also
                  after notice from either party of intention to terminate this
                  Lease, or at any time within six (6) months prior to the
                  expiration of the Lease, a "For Rent" sign, or both "For Sale"
                  and "For Rent" signs, and all said signs shall be placed upon
                  such part of the Leased Premises as Landlord shall require,
                  except on doors leading into the Leased Premises. Prospective
                  purchasers or tenants authorized by Landlord may inspect the
                  Leased Premises at reasonable hours at any time.

ARTICLE 7. LIABILITY INSURANCE AND INDEMNIFICATION

7.1      Insurance. During the term of this Lease, Tenant, at Tenant's expense,
         shall keep the building of which the Leased Premises are a part insured
         against loss or damage by fire and the hazards covered by extended
         coverage insurance in an amount equal to not less than the full
         insurable value of such building. The policy or policies therefor shall
         name Landlord as insured and shall be payable to Landlord. Tenant shall
         not commit or permit any acts in or about the Leased Premises which may
         in any way impair or invalidate such policy or policies of insurance
         for the building.

         Tenant shall be solely responsible for obtaining any fire or extended
         coverage insurance for personal property and improvements of Tenant and
         for all goods, commodities and materials stored by Tenant in or about
         the Leased Premises. Tenant agrees that if any property owned by it and
         located in the Leased Premises shall be damaged or destroyed, Landlord
         shall not have any liability to Tenant, nor to any insurer of Tenant,
         for or in respect of such damage or destruction, and Tenant shall
         require all policies of risk insurance carried by it on its property in
         the Leased Premises to contain or be endorsed 


                                      - 9 -
<PAGE>   11
         with a provision in and by which the insurer designated therein shall
         waive its right of subrogation against Landlord.

7.2      Operations of Tenant. All operations conducted by Tenant shall be at
         Tenant's sole risk. In addition, Tenant shall procure and keep in force
         at its own expense public liability insurance and comprehensive general
         liability insurance, including contractual liability insurance
         sufficient to cover all phases and aspects of the operation and conduct
         of its business, with minimum limits of $1,000,000 on account of bodily
         injuries to or death of one person, and $3,000,000 on account of bodily
         injuries to or death of more than one person as the result of any one
         accident or disaster, and $1,000,000 on account of damage to property.

7.3      Policy Requirements. All insurance policies required of Tenant in this
         Lease shall name as insured both Landlord and Tenant (and upon request,
         any other party named by Landlord) and shall contain an express waiver
         of any right of subrogation against Landlord and other named insureds
         designated by Landlord. All policies shall be in such companies as are
         authorized to write such coverage in Arizona, shall be acceptable to
         Landlord and/or its lender (which shall be named as an additional
         insured if requested in writing). Tenant will further deposit the
         policy or policies of such insurance or certificates thereof, with
         Landlord with evidence of payment of premium at all times commencing
         with the date of this Lease. Each policy shall provide against
         cancellation without thirty (30) days prior written notice to the named
         insureds.

7.4      Failure to Procure Insurance. In the event Tenant shall fail to procure
         insurance required under this Article 7 and fails to maintain such
         insurance in force continuously during the term of this Lease, Landlord
         shall be entitled to procure such insurance, and Tenant shall
         immediately reimburse Landlord for such premium expense.

7.5      Indemnification and Waiver of Claims. Tenant indemnifies Landlord and
         waives claims as follows:

         7.5.1    Indemnification. Tenant will indemnify Landlord and save it
                  harmless from and against any and all claims, actions,
                  damages, liability and expense in connection with loss of
                  life, personal injury and/or damage to property occurring in
                  or about, or arising from or out of, the Leased Premises and
                  adjacent sidewalks and loading platforms or areas or
                  occasioned wholly or in part by any act or omission of Tenant,
                  its agents, contractors, customers or employees. Additionally,
                  Tenant agrees to indemnify and hold harmless Landlord with
                  respect to any claim, cause of action or proceeding, in law or
                  in equity, civil, criminal or administrative, asserted or
                  brought by any person, firm or corporation. Tenant agrees to
                  defend at its own cost and expense any lawsuit or proceeding
                  referred to above and to reimburse Landlord for any reasonable
                  expenses or damages, including reasonable


                                     - 10 -
<PAGE>   12
                  attorney's fees, incurred in any such proceeding, lawsuit,
                  administrative action, or investigation commenced in whole or
                  in part by reason of said exclusive clause.

         7.5.2    Waiver of Claims. Landlord and Landlord's agents, employees
                  and contractors shall not be liable for, and Tenant hereby
                  releases all claims for, damage to person and property
                  sustained by Tenant or any person claiming through Tenant
                  resulting from any theft, fire, accident, occurrence or
                  condition in or upon the Leased Premises or building of which
                  they shall be a part.

                           In the event the Leased Premises or its contents are
                           damaged or destroyed by fire or other insured
                           casualty, the rights, if any, of either party hereto
                           against the other with respect to such damage or
                           destruction are waived; and all policies of fire
                           and/or extended coverage or other insurance covering
                           the Leased Premises or its contents shall contain a
                           clause or endorsement providing in substance that the
                           insurance shall not be prejudiced if the insureds
                           have waived the right of recovery from any person or
                           persons prior to the date and time of loss or damage,
                           if any.

         7.5.3    Notice of Claims or Suits. Tenant agrees to promptly notify
                  Landlord of any claim, action, proceeding or suit instituted
                  or threatened against Landlord. In the event Landlord is made
                  a party to any action for damages which Tenant has herewith
                  indemnified Landlord against, then Tenant shall pay all costs
                  and shall provide effective counsel in such litigation or
                  shall pay, at Landlord's option, the attorney fees and costs
                  incurred in connection with said litigation by Landlord.

ARTICLE 8. LOSS, DESTRUCTION OR TAKING OF LEASED PREMISES

8.1      Fire or Other Casualty. Tenant shall give to Landlord prompt written
         notice of any accident, fire or damage occurring on or to the Leased
         Premises and shall fully cooperate with Landlord in filing all
         necessary proofs of claim with insurance companies. The proceeds of
         such insurance applicable to the Leased Premises shall be paid to
         Landlord and Landlord shall rebuild, repair or restore the Leased
         Premises to the condition at the time immediately preceding the loss or
         damage; provided, however, that Landlord may elect to retain such
         insurance proceeds and shall not be required to rebuild, repair or
         restore the Leased Premises, and this Lease shall be terminated, if
         such damage or destruction occurs within the last year of the term of
         this Lease, or if more than one-third (1/3) of the Leased Premises is
         so damaged or destroyed. In the event of total destruction of the
         Leased Premises, the rent shall abate during the period of rebuilding,
         repair or restoration by Landlord, or, in the event of partial
         destruction of the Leased Premises, the rent shall abate pro rata
         during the period of rebuilding, repair or restoration by Lessor.

8.2      Condemnation. If title to all or any portion of the Leased Premises be
         taken by a public or quasi-public authority under any statute or by
         right of eminent domain of any 


                                     - 11 -
<PAGE>   13
         governmental body, whether such loss or damage results from
         condemnation of part or all of the Leased Premises, Tenant shall not be
         entitled to participate or receive any part of the damages or award
         except where said award shall provide for moving or other reimbursable
         expenses for Tenant under applicable statute, in which event the latter
         sum shall be received by Tenant, and except that portion of any award
         allocated to the taking of Tenant's trade fixtures, equipment and
         personal property, or to a loss of business by Tenant. None of the
         awards or payments to Landlord shall be subject to any diminution or
         apportionment on behalf of Tenant or otherwise.

         If any power of eminent domain is exercised during the term of this
         Lease, such exercise shall not void or impair this Lease unless the
         amount of the Leased Premises so taken is such as to substantially and
         materially impair the usefulness of the Leased Premises for the purpose
         of which they are hereby demised, in which event either party may
         cancel this Lease by notice to the other within sixty (60) days after
         possession is taken, and the rental herein provided shall abate as of
         the date possession is taken by the condemning authority.

         If a portion of the Leased Premises shall be taken as herein provided
         for public improvements or otherwise under the exercise of the right of
         eminent domain and the Leased Premises shall continue to be reasonably
         suitable for the use which is hereby authorized, then the rental herein
         provided shall be reduced from the date of such taking in direct
         proportion to the reduction in usefulness of the Leased Premises.

ARTICLE 9. ASSIGNMENT, SUBLETTING, MORTGAGING AND SUBORDINATION

9.1      Assignment and Subletting by Tenant. Tenant shall not convey, assign,
         mortgage, pledge or encumber this Lease, in whole or in part, nor
         sublet the whole or any part of the Leased Premises, or permit the use
         of the whole or any part of the Leased Premises by any licensee or
         concessionaire, without first obtaining the written consent of
         Landlord. This prohibition shall be construed to include a prohibition
         against any assignment or subletting by operation of law, assignment
         for the benefit of creditors, voluntary or involuntary bankruptcy or
         reorganization, or otherwise, without the prior written consent of
         Landlord. Any assignment or sublease without Landlord's written consent
         is in violation of this Lease and a default hereunder and, at the
         option of Landlord, shall be voidable.

         Landlord's consent or refusal to consent to any such subletting may be
         based upon, but shall not be limited to, factors pertaining to (a) the
         acceptability of the proposed subtenant to the Leased Premises, and (b)
         the financial statement, credit and ability of any proposed subtenant
         to meet the obligations, terms and conditions of this Lease.

         The acceptance of any rental payments by Landlord from any alleged
         assignee shall not constitute approval of the assignment of this Lease
         by the Landlord, and the consent by Landlord to one assignment or
         subletting of the Leased Premises shall not constitute a waiver of
         Landlord's rights hereunder.


                                     - 12 -
<PAGE>   14
         Tenant shall pay to Landlord the sum of $500.00 as a Transfer Fee for
         such written consent. In the event of any such assignment, subletting,
         licensing or granting of a concession, made with the written consent of
         the Landlord as aforesaid, Tenant will nevertheless remain liable for
         the performance of all the terms, conditions, and covenants of this
         Lease. Any permitted assignment or subletting shall be by agreement in
         form and content acceptable to Landlord, and shall specify and require
         that each subtenant or assignee acquiring this Lease by acceptance of
         any sublease, assignment or transfer shall assume, be bound by, and be
         obligated to perform the terms and conditions of its sublessor and
         assignor under this Lease. A condition of such assignment or subletting
         is the agreement of the parties that Landlord shall receive the full
         and complete rental payment of subtenant or assignee, though such
         payments may be in excess of the original rental between Landlord and
         Tenant. It is the intent and understanding of the parties to this
         Agreement that Tenant shall not receive any monetary benefit in excess
         of the actual rental obligation of Tenant as agreed between the
         original Tenant and Landlord through a sublease or assignment to a
         third party. In the event of default of Tenant, Landlord, at Landlord's
         sole option, may succeed to the position of Tenant as to any subtenant
         or licensee of Tenant.

9.2      Assignment and Mortgaging by Landlord. The term "Landlord" as used in
         this Lease means the owner of the Leased Premises. So long as all sums
         held on Tenant's behalf in trust or escrow by Landlord are paid over to
         any purchaser of said Leased Premises, Landlord shall be and is hereby
         relieved of all covenants and obligations of Landlord hereunder after
         the date of sale of the Leased Premises, and it shall be construed
         without further agreement between the parties that the purchaser has
         assumed and agreed to carry out any and all covenants and obligations
         of Landlord hereunder from the date of such sale.

9.3      Subordination. This Lease shall, upon request by Landlord, be subject
         and subordinate to any and all leases, mortgages or deeds of trust
         hereinafter placed upon the Leased Premises, or any part thereof, and
         to all future modifications, consolidations, replacements, extensions
         and renewals of, and all amendments and supplements to said leases,
         mortgages or deeds of trust. Notwithstanding such subordination as
         aforesaid, this Lease, except as otherwise hereinafter provided, shall
         not terminate or be divested by foreclosure or other default
         proceedings under said leases, mortgages, deeds of trust, or
         obligations secured thereby, and Tenant shall attorn to and recognize
         the landlord, mortgagee, trustee, beneficiary or the purchaser at the
         foreclosure sale in the event of such foreclosure or other default
         proceeding, as Tenant's Landlord hereunder for the balance of the term
         of this Lease, subject to all of the terms and provisions hereof.

9.4      Offset Statement. Tenant agrees to execute, acknowledge and deliver any
         and all documents required to effectuate the provisions of this Article
         9, and within ten (10) days after request therefor by Landlord or in 
         the event that upon any sale, assignment, lease or hypothecation of the
         Leased Premises and/or the land thereunder by Landlord, an offset


                                     - 13 -
<PAGE>   15
         statement shall be required by Tenant, Tenant agrees to deliver in
         recordable form a certificate (if such be the case) that this Lease is
         in full force and effect and there are no defenses or offsets thereto,
         or stating those claimed by Tenant, and the dates to which rental or
         other sums have been paid in advance, it being intended that any such
         statement delivered pursuant to this Paragraph 9.4 may be relied upon
         by any prospective purchaser, mortgagee, assignee or beneficiary.
         Tenant shall also deliver to any prospective institutional lender of
         Landlord, upon Landlord's reasonable request therefor, from time to
         time, Tenant's latest financial statements and such specific
         subordination agreement on Lender's form as may be required by Lender.
         Tenant acknowledges and agrees that the promises to issue statements
         pursuant to this Paragraph 9.4 are a material consideration inducing
         Landlord to enter into this Lease, and that the breach of such promise
         shall be deemed a material breach of this Lease, and shall constitute a
         default hereunder.

ARTICLE 10. DEFAULT AND REMEDIES FOR DEFAULT

10.1     Events of Default. The occurrence of any of the following constitute an
         event of default hereunder:

         10.1.1   Tenant Bankruptcy/Insolvency. The filing of a petition by or
                  against Tenant for adjudication as a bankrupt or insolvent, or
                  for its reorganization or for the appointment of a receiver or
                  trustee of Tenant's property; an assignment by Tenant for the
                  benefit of creditors; or the taking of possession of the
                  property of Tenant by any governmental officer or agency
                  pursuant to statutory authority for the dissolution or
                  liquidation of Tenant.

         10.1.2   Delinquency in Payment. Failure of Tenant to pay when due any
                  installment of rent hereunder or any other sum herein required
                  to be paid by Tenant, and the continuance of such nonpayment
                  for five (5) days after written notice from Landlord.

         10.1.3   Abandonment. Abandonment of the Leased Premises by Tenant.

         10.1.4   Failure to Perform Covenants. Tenant's failure to perform any
                  other covenant or condition of this Lease within twenty (20)
                  days after written notice and demand, unless the failure is of
                  such a character as to require more than twenty (20) days to
                  cure, in which event Tenant's failure to proceed diligently to
                  cure such failure shall constitute an event of default.

10.2     Remedies of Landlord for Default by Tenant. Upon the occurrence of an
         event of default, Landlord shall have the right, then or at any time
         thereafter, and while such event of default shall continue, and in
         addition to and not in lieu of any other remedies, relief or rights
         available to Landlord at law or equity or contained in this Lease, to
         do any of the following:


                                     - 14 -
<PAGE>   16
         10.2.1   Landlord Cure. Landlord by itself or its authorized agents may
                  cure the default and charge Tenant for the costs of such cure,
                  which charge shall be due and payable as rental under this
                  Lease immediately upon written notice to Tenant.

                  or any part thereof, and to remove all persons or personal
                  property by direct or summary action, or in a different type
                  of suit or proceeding, by force or otherwise, without being
                  deemed guilty of trespass or other actionable wrong by reason
                  thereof, and without being liable for the damages therefor or
                  in connection therewith, and, after demand made therefor,
                  Tenant or anyone in possession claiming under Tenant shall be
                  deemed guilty of unlawful detainer and subject to such summary
                  or other action as may be provided by law. Additionally,
                  Landlord may relet the Leased Premises as the agent for and in
                  the name of the Tenant, at any rental readily acceptable,

                  to relet and rent the same so as to realize a sum equal to the
                  rent hereby reserved, Tenant shall pay to Landlord any loss or
                  difference of rent for the remainder of the term.

         10.2.5   Termination of Lease. Landlord, irrespective of the date on
                  which its right of re-entry shall have accrued or be
                  exercised, shall have the right, whether for rent or
                  possession or otherwise, to forfeit this Lease and terminate
                  the state of tenancy hereby created. This right to terminate
                  is exercisable by a written notice to Tenant, which written
                  notice may be part of a notice of default previously delivered
                  to Tenant, and, as such, may be conditioned upon Tenant's
                  failure to cure the default and the event of default. The
                  termination may be made effective as of the event of default
                  or thereafter, and, if not otherwise specified, will be deemed
                  to be effective immediately. Upon such termination and
                  forfeiture, Landlord shall be entitled to and may take
                  immediate possession of the Leased Premises, any other notice
                  or demand being hereby waived. Such termination does not,
                  however, release Tenant from liability for rentals then
                  overdue or remaining under the Lease but shall operate to
                  accelerate the entire balance of the term rental, which shall
                  become immediately due and payable by Tenant, along with all
                  overdue rentals and charges.

10.3     Non-Waiver of Remedies. It is expressly agreed that neither the taking
         of possession of the Leased Premises nor the institution of any
         proceedings by way of unlawful detainer, ejectment, quiet title, or
         otherwise, to secure possession of the Leased Premises, nor the
         re-entry by Landlord with or without the institution of such
         proceedings, nor the rerenting or subletting of the Leased Premises,
         shall operate to terminate this Lease in whole or in part, nor of
         itself constitute an exercise of Landlord's option to do so, but only
         by the giving of the written notice specifically specifying termination
         shall such termination be effected.

         In the event Tenant breaches this Lease, or any covenant, term or
         condition hereunder, and abandons the Leased Premises, this Lease shall
         continue in force and effect for so long as the Landlord does not
         terminate Tenant's right to possession, and Landlord may enforce all
         rights and remedies of Landlord including, without limitation, the
         right to recover rental as it becomes due hereunder. Acts of
         maintenance or preservation or efforts to relet the Leased Premises, or
         the appointment of a receiver upon the initiation of the Landlord to
         protect the Landlord's interest under this Lease shall not constitute a
         termination of Tenant's right to possession.

         Waiver by Landlord of any default, breach or failure of Tenant under
         this Lease shall not be construed as a wavier of any subsequent or
         different default, breach or failure. In case of a breach by Tenant of
         any of the covenants or undertakings of Tenant, Landlord nevertheless
         may accept from Tenant any payments hereunder without in any way
         waiving Landlord's right to exercise the remedies hereinbefore provided
         for by reason of any other breach or lapse which was in existence at
         the time such payment or payments were accepted by Landlord.

         It is expressly understood that the enumeration herein of express
         rights, options and privileges shall not limit Landlord nor deprive
         Landlord of any other remedy or action or cause of action by reason of
         any default of Tenant, including the right to recover from Tenant any
         deficiency upon re-renting.

         The specific remedies to which Landlord may resort under the terms of
         this Lease are cumulative and are not intended to be exclusive of any
         other remedies or means of redress to which they may be lawfully
         entitled in case of any breach or threatened breach by either of them
         or of any provisions of this Lease.

ARTICLE 11. GENERAL PROVISIONS

11.1     No Brokers. Neither Landlord nor Tenant has employed a broker who has
         or may have a legitimate claim to a commission arising from Tenant's

         subject to the provisions of Article 9; provided, however, that the
         liability of Landlord hereunder and any successor in interest and title
         to the Leased Premises shall be limited to its interest in the Leased
         Premises, and no other assets of the Landlord other than its interest
         in the Leased Premises shall be affected by reason of any liability
         which said Landlord or successor in interest may have under this Lease.

11.4     Notices. Wherever in this Lease it shall be required or permitted that
         notice or demand be given or served by either party to this Lease to or
         on the other, such notice or demand shall not be deemed to have been
         duly given or served unless made in writing and either personally
         delivered or forwarded by certified mail, return receipt requested,
         postage prepaid, to the address for each party provided below. Such
         addresses may be changed from time to time by either party by serving
         notices as above provided. While Tenant is in possession of the Leased
         Premises, notices to the Tenant may also be delivered or forwarded by
         certified mail to the Leased Premises.

                  only agreement between the parties hereto pertaining to the
                  Leased Premises. It is understood that there are no oral

                  displayed by Landlord to Tenant with respect to the subject
                  matter thereof, and none shall be used to interpret or
                  construe this Lease. It is further agreed by and between the
                  parties hereto that there shall be no modification or
                  amendment to this Lease, except as may be executed in writing
                  between the parties hereto. It is further understood by Tenant
                  that Landlord may not now, or in the future, own all of the
                  Leased Premises. Tenant agrees not to cancel its Lease,
                  reduce, abate, or offset rents, or pursue any other remedies
                  under this Lease, or at law or equity, with respect to
                  Landlord, for any violation, breach or default of this Lease
                  by virtue of any act or omission on, or with respect to,
                  property not owned by Landlord.

         11.6.2   Headings/Captions. The headings or captions of Articles or
                  Paragraphs in this Lease are for convenience and reference
                  only and they in no way define, limit, or describe the scope
                  or intent of this Lease or the provisions of such Articles.

                  and each gender shall include all genders. Landlord and

                  referred to in or made a part of this Lease, shall likewise
                  include both the singular and the plural, a corporation,
                  co-partnership, individual or person acting in any fiduciary
                  capacity as executor, administrator, trustee, or in any other
                  representative capacity. All covenants herein contained on the
                  part of Tenant shall be joint and several.

         11.6.4   Time of Essence. Time is hereby expressly declared to be of
                  the essence of this Lease and of each and every covenant,
                  term, condition and provision hereof.

         11.6.5   Impartial Construction. The language in all parts of this
                  Lease shall be in all cases construed as a whole according to
                  its fair meaning and not strictly for nor against either
                  Landlord or Tenant.

         11.6.6   Governing Law. The laws of the State in which the Leased
                  Premises are located shall govern the validity,
                  interpretation, performance and enforcement of this Lease.

         11.6.7   Partial Invalidity. If any term covenant or condition of this
                  Lease or the application thereof to any person or circumstance
                  shall, to any extent, be invalid or unenforceable, the
                  remainder of this Lease, or the application of such term
                  covenant or condition to persons or circumstances other than
                  those as to which it is held invalid or unenforceable shall
                  not be affected thereby, and each term, covenant or condition
                  of this Lease shall be valid and be enforced to the fullest
                  extent permitted by law.

                  of this Lease shall be without force and effect, all
                  amendments to be in writing executed by the parties or their
                  respective successors in interest.

11.7     Execution and Delivery of Lease. The submission of this Lease for
         examination does not constitute a reservation or option for the Leased
         Premises. This Lease shall be executed in duplicate and shall become
         effective as of the date first written only when an executed original
         is delivered to each party.

their own behalf or through their duly authorized representative.

                                      LEASE


                  THIS LEASE is entered into as of the 1st day of May, 1997, by
and between 19th AVENUE/BUCHANAN LIMITED PARTNERSHIP, an Arizona limited
partnership ("Landlord"), and SCHUFF STEEL COMPANY, an Arizona corporation
("Tenant").

ARTICLE 1. LEASED PREMISES

1.1      Leased Premises. Landlord leases to Tenant the land and improvements
         located at 1841 W. Buchanan Street, Phoenix, Arizona, as more
         particularly described on Exhibit "A" ("Leased Premises").

ARTICLE 2. TERM

2.1      Term of Lease. The term of this Lease shall be twenty (20) years
         commencing on May 1, 1997 and ending on April 30, 2017.

2.2      Quiet Enjoyment. Landlord agrees that so long as the rent is being paid
         in the manner and at the time prescribed and the covenants and
         obligations of Tenant are being all and singularly kept, fulfilled and
         performed, Tenant shall lawfully and peaceably have, hold, possess, use
         and occupy and enjoy the Leased Premises so long as this Lease remains
         in force without hindrance, disturbance or molestation from Landlord,
         subject to the specific provisions of this Lease.

2.3      Surrender of Leased Premises. Upon any termination of this Lease,
         whether by lapse of time, cancellation pursuant to an election provided
         for herein, forfeiture, or otherwise, Tenant shall immediately
         surrender possession of the Leased Premises and all buildings and
         improvements on the same to Landlord in good and tenantable repair,
         reasonable wear and damage from fire or other casualty or peril
         excepted, and shall surrender all keys for the Leased Premises to
         Landlord at the place then fixed for the payment of rent and shall
         inform Landlord of all combinations of locks, safes and vaults, if any,
         in the Leased Premises.

         At any time during the ten (10) days before the termination date of
         this Lease, Tenant, if not in default hereunder at such time, shall
         have the right to remove, and at the end of the term, if directed to do
         so by Landlord, shall remove from the Leased Premises all furniture,
         furnishings, signs, and equipment then installed or in place in, on or
         about the Leased Premises; provided, however, Tenant shall, and it
         covenants and agrees to, make all repairs to the Leased Premises
         required because of such removal. If any of such property shall remain
         on the Leased Premises after the end of the term hereof, such property
         shall be and become the property of Landlord without any claim therein
         of Tenant. Landlord may direct Tenant to remove such property, in which
         case Tenant


                                      - 1 -
<PAGE>   6
         agrees to do so, and to reimburse Landlord for any expense of removal
         in the event Tenant shall fail to remove such property if and when
         directed.

         Upon termination of this Lease, Tenant shall peaceably surrender the
         Leased Premises, including all fixtures and tenant improvements, in a
         neat and broom clean condition, and Tenant shall repair any holes or
         openings made by Tenant in the walls, roof or floor of the building,
         remove any protuberance and perform any maintenance or repairs required
         of Tenant by this Lease. If directed to do so by Landlord, Tenant shall
         also remove any improvements, additions or alterations made to the
         Leased Premises by Tenant even though such improvements by the terms of
         this Lease become a part of the Leased Premises.

2.4      Holding Over. If Tenant, upon expiration or termination of this Lease,
         either by lapse of time or otherwise, remains in possession of the
         Leased Premises with Landlord's written consent but without a new lease
         reduced to writing and duly executed, Tenant shall be deemed to be
         occupying the Leased Premises as a tenant at will, subject to all the
         covenants, conditions and agreements of this Lease. If Tenant remains
         in possession without Landlord's written consent, Tenant shall be
         deemed to be in wrongful holdover and shall be subject to all the
         rights and remedies provided to Landlord under this Lease and the
         applicable laws, including any forcible entry and detainer actions or
         other eviction processes.

2.5      Abandonment. If Tenant, prior to the expiration or termination of this
         Lease by lapse of time or otherwise, relinquishes possession of the
         Leased Premises without Landlord's written consent, such relinquishment
         shall be deemed to be an abandonment of the Leased Premises and an
         event of default under this Lease.

ARTICLE 3. RENTALS AND OTHER TENANT CONTRIBUTIONS

3.1      Minimum Rent. Tenant shall pay to Landlord minimum annual rent in the
         amount of One Hundred Thirty-five Thousand Dollars ($135,000.00) per
         year, payable in advance in equal monthly installments of Eleven
         Thousand Two Hundred Fifty Dollars ($11,250.00) ("Minimum Rent") on the
         first day of each calendar month, without prior demand therefor.

3.2      Adjustment of Minimum Rent. The minimum annual rent is subject to
         adjustment every five (5) years during the term of this Lease, with
         each adjustment to commence on May 1 of the year of adjustment
         ("Adjusted Minimum Rent"). The Adjusted Minimum Rent shall be effective
         as of May 1, 2002, May 1, 2007, and May 1, 2012 during the term hereof,
         with the Adjusted Minimum Rent payable in advance in equal monthly
         installments on the first day of each calendar month thereafter,
         without prior demand therefor.

         3.2.1    Computation of Adjusted Minimum Rent. The Adjusted Minimum
                  Rent shall be computed based on the increase in the Consumer
                  Price Index - U.S. City average - All Urban Consumers
                  ("Index") as published by the United States Department of
                  Labor's Bureau of Labor Statistics over the base period index.
                  The base period index shall be the index for the calendar
                  month of March 1996. The base period index shall be compared
                  with the Index for the same calendar month for each subsequent
                  March in the year immediately preceding the effective date of
                  each adjustment (comparison month). If the Index for any
                  comparison month is higher than the base period index, then
                  the Minimum Rent for the next succeeding adjustment period
                  shall be increased by the identical percentage commencing with
                  the next succeeding May 1. In no event shall the Minimum Rent
                  be less than that the amount paid immediately prior to any
                  such adjustment.

         3.2.2    Use of Different Index. If the Bureau discontinues the
                  publication of the Index, or publishes it less frequently, or
                  alters it in any manner, then Landlord shall adopt a
                  substitute index or substitute procedure which reasonably
                  reflects and monitors consumer prices.

3.3      Payment of Rent. Tenant shall, without prior notice or demand and
         without any setoff or deduction whatsoever, pay all rentals and other
         charges and render all statements herein prescribed at the Landlord's
         address or to such other person or corporation, and at such other
         place, as shall be designated by Landlord in writing at least ten (10)
         days prior to the next ensuing rental payment date.

3.4      Taxes.

         3.4.1    Rent Tax. Tenant shall pay as additional rent, any privilege
                  tax, sales tax, gross proceeds tax, rent tax or like tax (but
                  not including income tax), now or hereafter levied, assessed
                  or imposed by any federal, state, county or municipal
                  governmental authority, or any subdivision thereof, upon any
                  rent or other payments require to be paid under this Lease.

         3.4.2    Personal Property Tax. Tenant shall pay before delinquent, as
                  additional rent, all personal property taxes and assessments
                  levied or assessed by any governmental authority against any
                  personal property or fixtures of Tenant in, on or about the
                  Leased Premises.

         3.4.3    Real Property Tax. Tenant shall pay before delinquent,
                  exhibiting receipts to Landlord on demand, all real property
                  taxes and assessments levied or assessed against the Leased
                  Premises and improvements thereon, all water charges or
                  assessments levied in connection with any improvements or
                  irrigation projects, or district or other taxes, assessments
                  or governmental charges of any kind levied or assessed against
                  the Leased Premises. Tenant shall have the right, in good
                  faith and at its sole and own cost and expense and in its own
                  name or in the name


                                      - 3 -

                  of Landlord, to protest or contest or seek to have reviewed,
                  reduced, equalized or abated any tax or assessment by legal
                  proceedings in such manner as it may deem advisable. No
                  protest, contest or other action, however, shall be maintained
                  by Tenant after the time limited for the payment without
                  penalty or interest of the tax or assessment unless Tenant
                  shall have first paid the amount of such tax or assessment
                  under protest or shall have procured a stay of proceedings to
                  enforce the collection thereof, and shall have also provided
                  for the payment thereof, together with all penalties,
                  interest, cost and expenses, by the deposit of a bond in form
                  approved by Landlord if required by law to accomplish such
                  stay.

3.5      Interest. Tenant covenants and agrees that all sums to be paid under
         this Lease, if not paid when due, shall bear interest on the unpaid
         portion thereof at the rate of eighteen (18%) per annum from the date
         when due. If Landlord shall pay any monies, or incur any expenses in
         correction of any violation of any covenant of Tenant herein set forth,
         the amounts so paid, or, incurred shall, at Landlord's option and on
         notice to Tenant, be considered additional rentals payable by Tenant
         with the first installment of rental thereafter to become due and
         payable, and may be collected or enforced as by law provided with
         respect to rentals.

3.6      Utilities Consumed on Leased Premises. In addition to all rentals
         herein specified, Tenant shall be responsible for and shall pay for all
         utilities used or consumed in or upon the Leased Premises, and all
         sewer charges, as and when the charges therefor shall become due and
         payable, throughout the term of this Lease. Tenant shall make all
         appropriate applications to the local utility companies and pay all
         required deposits for meters and service for all utilities.

         In the event any utility or utility service (such as water or sewage
         disposal) are furnished to Tenant for which a lien could be filed
         against the Leased Premises or any portion thereof, Tenant shall, at
         Landlord's request, pay the cost thereof to Landlord as and when the
         charges therefor become due and payable; otherwise, Tenant shall
         deliver original receipted bills to Landlord within thirty (30) days
         after the same are due and payable without interest or penalty.

         In no event shall Landlord be liable for any interruption or failure in
         the supply of any utilities to the Leased Premises.

ARTICLE 4. SECURITY

4.1      Landlord's Lien. Landlord shall have a general lien on the leasehold
         estate hereby created and on all property kept or used on the Leased
         Premises, whether such property is exempt from execution or not, to
         secure payment of any and all monies then due or thereafter becoming
         due to Landlord under the terms and conditions of this Lease, and to
         secure the prompt performance and fulfillment by Tenant of each and
         every one of said terms and conditions. The lien as provided for in
         this Paragraph 4.1 attaches as of


                                      - 4 -
<PAGE>   9
         the date of execution hereof and shall remain in full force and effect
         unless expressly waived by Landlord in writing.

4.2      Security in Addition to Other Remedies. The security given Landlord in
         this Article 4 shall not limit, replace or obviate the remedies of
         Landlord upon a default by Tenant as described in Article 10 below,
         including the right of Landlord to re-enter the Leased Premises,
         distrain for rent or pursue its general lien upon Tenant's property in
         the Leased Premises described in Paragraph 4.1 above.

ARTICLE 5. CONSTRUCTION, ALTERATIONS, MAINTENANCE AND REPAIRS

5.1      Tenant's Duty to Repair. Landlord shall not be called upon to make any
         improvements or repairs of any kind upon the Leased Premises and
         appurtenances unless such repairs are necessitated by the misuse or
         negligence of Landlord. Tenant shall keep and maintain in good order,
         condition and repair (including any such replacement, periodic
         painting, and restoration as is required for that purpose) the Leased
         Premises and every part thereof and any and all appurtenances hereto
         located. Any of the foregoing repairs required to be made by reason of
         the negligence of Landlord shall be the responsibility of the Landlord
         notwithstanding the provisions above contained in this paragraph.

         If Tenant refuses or neglects to commence and to complete repairs or
         maintenance required herein promptly and adequately, Landlord may, but
         shall not be required to, make and complete said repairs, and Tenant
         shall pay the cost thereof to Landlord as additional rent upon demand.
         Except as provided in Paragraph 8.1 (Fire and Casualty damage) and 8.2
         (Condemnation), Landlord shall not be obligated to repair, replace,
         maintain or alter the Leased Premises, and Tenant waives all laws in
         contravention thereof. With regard to repairs, Tenant expressly waives
         any right pursuant to any law now existing or which may be effective
         during the term hereof, to make repairs at Landlord's expense.

5.2      Tenant's Alterations and Improvements to Leased Premises. Tenant shall
         not make or cause to be made any alterations, additions or improvements
         to the building, or make any changes to the exterior of the building
         without first obtaining Landlord's written approval and consent.

         Tenant shall present to the Landlord plans and specifications for such
         work at the time approval is sought. No addition, alteration, change or
         improvement shall be made which will weaken the structural strength,
         lessen the value of, or change the architectural appearance of any
         building or other construction.

         Landlord may condition its approval of any additions or alterations by
         Tenant on the requirement that Tenant or its contractor secure and bear
         the cost of a labor and materials


                                      - 5 -
<PAGE>   10
         payment bond for the amount of the proposed construction reflecting
         Landlord as an obligee.

         All building materials and fixtures installed by Tenant shall be new or
         completely reconditioned. All alterations, improvements, additions and
         fixtures made or installed by Tenant as aforesaid shall remain upon the
         Leased Premises at the expiration or earlier termination of this Lease
         and shall become the property of Landlord, unless Landlord shall, prior
         to the expiration or termination of this Lease, have given written
         notice to Tenant to remove the same, in which event Tenant shall remove
         the same and restore the Leased Premises to the same good order and
         condition in which it was at the commencement of this Lease. Should
         Tenant fail so to do, Landlord may do so, collecting, at Landlord's
         option, the cost and expense thereof from the Tenant as additional
         rent.

5.3      Furniture, Trade Fixtures and Equipment. Tenant shall not cut or drill
         into, or secure any trade fixtures, apparatus or equipment of any kind
         to any part of the Leased Premises without first obtaining the written
         consent of Landlord. All furnishings, trade fixtures, equipment, and
         machines installed by Tenant in the Leased Premises shall be new or
         completely reconditioned and remain the property of Tenant subject to
         Landlord's security interest as defined at Paragraph 4.1 above and 
         shall be removable at the expiration or earlier termination of this
         Lease or any renewal or extension thereof, provided Tenant shall not
         at such time be in default under any covenant or agreement contained
         in this Lease; and provided further, that in the event of such
         removal, Tenant shall promptly restore the Leased Premises to their
         original order and condition. Any such equipment not removed at or
         prior to such termination shall be and become the property of
         Landlord.

5.4      Initial Installation and Improvements by Tenant. Tenant shall submit to
         Landlord complete architectural, electrical and mechanical plans and
         specifications covering all work which Tenant proposes to do in the
         Leased Premises including the fixturing thereof, whether such work is
         to be done by Tenant or others. Such plans and specifications shall be
         prepared in such detail as Landlord may require, and Tenant agrees not
         to commence work upon any portion of the Leased Premises until Landlord
         has approved such plans and specifications in writing. Landlord agrees
         to act with reasonable promptness with respect to such plans and
         specifications. Any changes in said plans or specifications must be
         similarly approved by Landlord.

         All of Tenant's work and installations shall be done in a first class,
         workmanlike manner and in compliance with all laws, rules, regulations
         and orders of all governmental authorities having jurisdiction thereof,
         and, in the performance of Tenant's work, Tenant shall engage and
         employ only such labor as will not cause any conflict or controversy
         with any labor organization representing trades performing work for
         Landlord or others in the Leased Premises.


                                      - 6 -
<PAGE>   11
         Tenant shall, at Tenant's own expense, promptly remove from the Leased
         Premises all trash and debris which may accumulate in connection with
         Tenant's work in the Leased Premises.

         Landlord shall have no liability or responsibility for loss of, or any
         damage to fixtures, equipment or other property of Tenant so installed
         or placed on the Leased Premises.

5.5      Mechanic's Lien. If Tenant makes any alterations or improvements in the
         Leased Premises, Tenant must pay for them when made. Nothing in the
         Lease shall be construed to authorize Tenant or any person dealing with
         or under Tenant, to charge the rents of the Leased Premises, or the
         property of which the Leased Premises form a part, or the interest of
         Landlord in the estate of the Leased Premises, or any person under and
         through whom Landlord has acquired its interest in the estate of the
         Leased Premises, with a mechanic's lien or encumbrance of any kind, and
         under no circumstances shall Tenant be construed to be the agent,
         employee or representative of Landlord in the making of such
         alterations or improvements to the Leased Premises, but, on the
         contrary, the right or power to charge any lien, claim or encumbrance
         of any kind against Landlord's rents or the Leased Premises or said
         land is denied. So long as the laws of this state shall provide for the
         filing of a statutory bond to eliminate the attachment of mechanic's or
         materialmen's liens to real estate, Tenant shall require that its
         contractor or itself shall take such steps as are provided by law for
         the filing of said statutory bond prior to the initiation of any
         construction. If a mechanic's or materialmen's lien is threatened by
         any contractor or supplier, or in the event of the filing of a notice
         of any such lien, Tenant will promptly take steps immediately to have
         any such lien removed. If the lien is not removed within ten (10) days
         from the date of written notice from Landlord, Landlord shall have the
         right at Landlord's option to cause the lien to be discharged by record
         of payment, deposit, bond or order of a court of competent jurisdiction
         or otherwise, to pay any portion thereof and of the amounts so paid,
         including attorney's fees and expenses connected therewith and interest
         at the rate of eighteen percent (18%) per annum on any sums paid or
         advanced, shall be deemed to be additional rent due from Tenant to
         Landlord and shall be paid to Landlord immediately upon rendition to
         Tenant of a bill therefor. Tenant will indemnify and save harmless
         Landlord from and against all loss, claims, damages, costs or expenses
         suffered by Landlord by reason of any repairs, installations or
         improvement, made by Tenant.

         Except as may be expressly provided in this Lease, nothing in this
         Article 5  shall be construed to permit Tenant to place any materials
         upon the Leased Premises or cause any labor or construction, or to make
         any alterations, additions, replacements or substantial repairs, in or
         about the Leased Premises. Landlord shall have the further right any
         time, and from time to time, to post and maintain on the Leased
         Premises such notices as Landlord deems necessary to protect the Leased
         Premises and Landlord, from all liens of any nature whatsoever.


                                      - 7 -
<PAGE>   12
         No mechanic's or materialmen's liens or mortgages, deeds of trust, or
         other liens of any character whatsoever created or suffered by Tenant
         shall in any way, or to any extent, affect the interest or rights of
         Landlord in any buildings or other improvements on the Leased Premises,
         or attach to or affect Landlord's title to or rights in the Leased
         Premises.

ARTICLE 6. USE OF LEASED PREMISES

6.1      Tenant's Use of Leased Premises. Tenant shall use and occupy the Leased
         Premises only for conducting its steel fabrication and erection
         business and related operations and for no other purpose without
         Landlord's prior written consent.

6.2      Conduct of Tenant's Operations. At all times throughout the Lease term,
         Tenant shall:

                  public authorities, and with the terms of any state or federal
                  statue or local ordinance or regulation applicable to Tenant
                  or its use, safety, cleanliness or occupation of the Leased
                  Premises, and save Landlord harmless from penalties, fines,
                  costs, expenses or damages resulting from failure to do so.

         6.2.2    Give to Landlord prompt written notice of any accident, fire
                  or damage occurring on or to the Leased Premises.

         6.2.3    Conduct its business in the Leased Premises in all respects in
                  a dignified manner and in accordance with high standards of

                  (5)      Comply with all reasonable rules and regulations of
                           Landlord in effect at the time of the execution of
                           this Lease or at any time or times, and from time to
                           time, promulgated by Landlord, which Landlord in its
                           sole discretion shall deem necessary in connection
                           with the demised Leased Premises, the building of
                           which the demised Leased Premises are a part or the
                           Shopping Center, including both the operation of
                           Tenant's business during certain minimum days and
                           hours and the installation of such fire
                           extinguishers, water buckets and other safety
                           equipment as Landlord may reasonably require.

6.3      Rights Reserved by Landlord.

         6.3.1    Easements. Landlord expressly reserves all rights in and with
                  respect to the land hereby leased not inconsistent with
                  Tenant's use of the Leased Premises as provided in the Lease,
                  including (without in anyway limiting the generality of the
                  foregoing) the rights of Landlord to enter upon the Leased
                  Premises and give easements to others for the purpose of
                  installing, using, maintaining, renewing and replacing such
                  overhead or underground water, gas, sewer and other pipe

                  lines, and telephone, electric, and power lines, cables and
                  conduits as Landlord may deem desirable in connection with the
                  development or use of any other property in the neighborhood
                  of the land hereby leased, whether owned by Landlord or not,
                  all of which pipelines, lines and conduits shall be buried to
                  a sufficient depth or raised to a sufficient height so as not
                  to interfere with the use or stability of the building or any
                  other improvements on the land hereby leased.

         6.3.2    Inspection. Landlord reserves the right to, at all reasonable
                  times, by itself or its duly authorized agents, employees and
                  contractors to go upon and inspect the demised Leased Premises
                  and every part thereof, to enforce or carry out the provisions
                  of this Lease, to perform any defaulted obligation of Tenant
                  or for any other proper purposes.

         6.3.3    Presentation for Sale or Lease. Landlord hereby reserves the
                  right during usual business hours to enter the Leased Premises
                  and to exhibit the same for purposes of sale, lease or

7.1      Insurance. During the term of this Lease, Tenant, at Tenant's expense,
         shall keep the building of which the Leased Premises are a part insured
         against loss or damage by fire and the hazards covered by extended
         coverage insurance in an amount equal to not less than the full
         insurable value of such building. The policy or policies therefor shall
         name Landlord as insured and shall be payable to Landlord. Tenant shall
         not commit or permit any acts in or about the Leased Premises which may
         in any way impair or invalidate such policy or policies of insurance
         for the building.

         Tenant shall be solely responsible for obtaining any fire or extended
         coverage insurance for personal property and improvements of Tenant and
         for all goods, commodities and materials stored by Tenant in or about
         the Leased Premises. Tenant agrees that if any property owned by it and
         located in the Leased Premises shall be damaged or destroyed, Landlord
         shall not have any liability to Tenant, nor to any insurer of Tenant,
         for or in respect of such damage or destruction, and Tenant shall
         require all policies of risk insurance carried by it on its property in
         the Leased Premises to contain or be endorsed with a provision in and
         by which the insurer designated therein shall waive its right of
         subrogation against Landlord.

7.2      Operations of Tenant. All operations conducted by Tenant shall be at
         Tenant's sole risk. In addition, Tenant shall procure and keep in force
         at its own expense public liability insurance and comprehensive general
         liability insurance, including contractual liability insurance
         sufficient to cover all phases and aspects of the operation and conduct
         of its business, with minimum limits of $1,000,000 on account of bodily
         injuries to or death of one person, and $3,000,000 on account of bodily
         injuries to or death of more than one person as the result of any one
         accident or disaster, and $1,000,000 on account of damage to property.

7.3      Policy Requirements. All insurance policies required of Tenant in this
         Lease shall name as insured both Landlord and Tenant (and upon request,
         any other party named by Landlord) and shall contain an express waiver
         of any right of subrogation against Landlord and other named insureds
         designated by Landlord. All policies shall be in such companies as are
         authorized to write such coverage in Arizona, shall be acceptable to
         Landlord and/or its lender (which shall be named as an additional
         insured if requested in writing). Tenant will further deposit the
         policy or policies of such insurance or certificates thereof, with
         Landlord with evidence of payment of premium at all times commencing
         with the date of this Lease. Each policy shall provide against
         cancellation without thirty (30) days prior written notice to the named
         insureds.

7.4      Failure to Procure Insurance. In the event Tenant shall fail to procure
         insurance required under this Article 7 and fails to maintain such
         insurance in force continuously during the term of this Lease, Landlord
         shall be entitled to procure such insurance, and Tenant shall
         immediately reimburse Landlord for such premium expense.

7.5      Indemnification and Waiver of Claims. Tenant indemnifies Landlord and
         waives claims as follows:

         7.5.1    Indemnification. Tenant will indemnify Landlord and save it
                  harmless from and against any and all claims, actions,
                  damages, liability and expense in connection with loss of
                  life, personal injury and/or damage to property occurring in
                  or about, or arising from or out of, the Leased Premises and
                  adjacent sidewalks and loading platforms or areas or
                  occasioned wholly or in part by any act or omission of Tenant,
                  its agents, contractors, customers or employees. Additionally,
                  Tenant agrees to indemnify and hold harmless Landlord with
                  respect to any claim, cause of action or proceeding, in law or
                  in equity, civil, criminal or administrative, asserted or
                  brought by any person, firm or corporation. Tenant agrees to
                  defend at its own cost and expense any lawsuit or proceeding
                  referred to above and to reimburse Landlord for any reasonable
                  expenses or damages, including reasonable attorney's fees,
                  incurred in any such proceeding, lawsuit, administrative
                  action, or investigation commenced in whole or in part by
                  reason of said exclusive clause.

         7.5.2    Waiver of Claims. Landlord and Landlord's agents, employees
                  and contractors shall not be liable for, and Tenant hereby
                  releases all claims for, damage to person and property
                  sustained by Tenant or any person claiming through Tenant
                  resulting from any theft, fire, accident, occurrence or
                  condition in or upon the Leased Premises or building of which
                  they shall be a part.

                           In the event the Leased Premises or its contents are
                           damaged or destroyed by fire or other insured
                           casualty, the rights, if any, of either party hereto
                           against the other with respect to such damage or
                           destruction are waived; and all policies of fire
                           and/or extended coverage or other insurance covering
                           the Leased Premises or its contents shall contain a
                           clause or endorsement providing in substance that the
                           insurance shall not be prejudiced if the insureds
                           have waived the right of recovery from any person or
                           persons prior to the date and time of loss or damage,
                           if any.

         7.5.3    Notice of Claims or Suits. Tenant agrees to promptly notify
                  Landlord of any claim, action, proceeding or suit instituted
                  or threatened against Landlord. In the event Landlord is made
                  a party to any action for damages which Tenant has herewith
                  indemnified Landlord against, then Tenant shall pay all costs
                  and shall provide effective counsel in such litigation or
                  shall pay, at Landlord's option, the attorney fees and costs
                  incurred in connection with said litigation by Landlord.

ARTICLE 8. LOSS, DESTRUCTION OR TAKING OF LEASED PREMISES

8.1      Fire or Other Casualty. Tenant shall give to Landlord prompt written
         notice of any accident, fire or damage occurring on or to the Leased
         Premises and shall fully cooperate with Landlord in filing all
         necessary proofs of claim with insurance companies. The proceeds of
         such insurance applicable to the Leased Premises shall be paid to
         Landlord and Landlord shall rebuild, repair or restore the Leased
         Premises to the condition at the time immediately preceding the loss or
         damage; provided, however, that Landlord may elect to retain such
         insurance proceeds and shall not be required to rebuild, repair or
         restore the Leased Premises, and this Lease shall be terminated, if
         such damage or destruction occurs within the last year of the term of
         this Lease, or if more than one-third (1/3) of the Leased Premises is
         so damaged or destroyed. In the event of total destruction of the
         Leased Premises, the rent shall abate during the period of rebuilding,
         repair or restoration by Landlord, or, in the event of partial
         destruction of the Leased Premises, the rent shall abate pro rata
         during the period of rebuilding, repair or restoration by Lessor.

8.2      Condemnation. If title to all or any portion of the Leased Premises be
         taken by a public or quasi-public authority under any statute or by
         right of eminent domain of any governmental body, whether such loss or
         damage results from condemnation of part or all of the Leased Premises,
         Tenant shall not be entitled to participate or receive any part of the
         damages or award except where said award shall provide for moving or
         other


                                     - 11 -
<PAGE>   16
         reimbursable expenses for Tenant under applicable statute, in which
         event the latter sum shall be received by Tenant, and except that
         portion of any award allocated to the taking of Tenant's trade
         fixtures, equipment and personal property, or to a loss of business by
         Tenant. None of the awards or payments to Landlord shall be subject to
         any diminution or apportionment on behalf of Tenant or otherwise.

         If any power of eminent domain is exercised during the term of this
         Lease, such exercise shall not void or impair this Lease unless the
         amount of the Leased Premises so taken is such as to substantially and
         materially impair the usefulness of the Leased Premises for the purpose
         of which they are hereby demised, in which event either party may
         cancel this Lease by notice to the other within sixty (60) days after
         possession is taken, and the rental herein provided shall abate as of
         the date possession is taken by the condemning authority.

         If a portion of the Leased Premises shall be taken as herein provided
         for public improvements or otherwise under the exercise of the right of
         eminent domain and the Leased Premises shall continue to be reasonably
         suitable for the use which is hereby authorized, then the rental herein
         provided shall be reduced from the date of such taking in direct
         proportion to the reduction in usefulness of the Leased Premises.

ARTICLE 9. ASSIGNMENT, SUBLETTING, MORTGAGING AND SUBORDINATION

9.1      Assignment and Subletting by Tenant. Tenant may convey, assign,
         mortgage, pledge or encumber this Lease, in whole or in part, and
         sublet the whole or any part of the Leased Premises, or permit the use
         of the whole or any part of the Leased Premises by any licensee or
         concessionaire, without first obtaining the written consent of
         Landlord.

9.2      Assignment and Mortgaging by Landlord. The term "Landlord" as used in
         this Lease means the owner of the Leased Premises. So long as all sums
         held on Tenant's behalf in trust or escrow by Landlord are paid over to
         any purchaser of said Leased Premises, Landlord shall be and is hereby
         relieved of all covenants and obligations of Landlord hereunder after
         the date of sale of the Leased Premises, and it shall be construed
         without further agreement between the parties that the purchaser has
         assumed and agreed to carry out any and all covenants and obligations
         of Landlord hereunder from the date of such sale.

9.3      Subordination. This Lease shall, upon request by Landlord, be subject
         and subordinate to any and all leases, mortgages or deeds of trust
         hereinafter placed upon the Leased Premises, or any part thereof, and
         to all future modifications, consolidations, replacements, extensions
         and renewals of, and all amendments and supplements to said leases,
         mortgages or deeds of trust. Notwithstanding such subordination as
         aforesaid, this Lease, except as otherwise hereinafter provided, shall
         not terminate or be divested by foreclosure or other default
         proceedings under said leases, mortgages, deeds of trust,


                                     - 12 -
<PAGE>   17
         or obligations secured thereby, and Tenant shall attorn to and
         recognize the landlord, mortgagee, trustee, beneficiary or the
         purchaser at the foreclosure sale in the event of such foreclosure or
         other default proceeding, as Tenant's Landlord hereunder for the
         balance of the term of this Lease, subject to all of the terms and
         provisions hereof.

9.4      Offset Statement. Tenant agrees to execute, acknowledge and deliver any
         and all documents required to effectuate the provisions of this Article
         9, and within ten (10) days after request therefor by Landlord or in
         the event that upon any sale, assignment, lease or hypothecation of the
         Leased Premises and/or the land thereunder by Landlord, an offset
         statement shall be required by Tenant, Tenant agrees to deliver in
         recordable form a certificate (if such be the case) that this Lease is
         in full force and effect and there are no defenses or offsets thereto,
         or stating those claimed by Tenant, and the dates to which rental or
         other sums have been paid in advance, it being intended that any such
         statement delivered pursuant to this Paragraph 9.4 may be relied upon
         by any prospective purchaser, mortgagee, assignee or beneficiary.
         Tenant shall also deliver to any prospective institutional lender of
         Landlord, upon Landlord's reasonable request therefor, from time to
         time, Tenant's latest financial statements and such specific
         subordination agreement on Lender's form as may be required by Lender.
         Tenant acknowledges and agrees that the promises to issue statements
         pursuant to this Paragraph 9.4 are a material consideration inducing
         Landlord to enter into this Lease, and that the breach of such promise
         shall be deemed a material breach of this Lease, and shall constitute a
         default hereunder.

ARTICLE 10. DEFAULT AND REMEDIES FOR DEFAULT

10.1     Events of Default. The occurrence of any of the following constitute an
         event of default hereunder:

         10.1.1   Tenant Bankruptcy/Insolvency. The filing of a petition by or
                  against Tenant for adjudication as a bankrupt or insolvent, or
                  for its reorganization or for the appointment of a receiver or
                  trustee of Tenant's property; an assignment by Tenant for the
                  benefit of creditors; or the taking of possession of the
                  property of Tenant by any governmental officer or agency
                  pursuant to statutory authority for the dissolution or
                  liquidation of Tenant.

         10.1.2   Delinquency in Payment. Failure of Tenant to pay when due any
                  installment of rent hereunder or any other sum herein required
                  to be paid by Tenant, and the continuance of such nonpayment
                  for five (5) days after written notice from Landlord.

         10.1.3   Abandonment. Abandonment of the Leased Premises by Tenant.


                                     - 13 -
<PAGE>   18
         10.1.4   Failure to Perform Covenants. Tenant's failure to perform any
                  other covenant or condition of this Lease within twenty (20)
                  days after written notice and demand, unless the failure is of
                  such a character as to require more than twenty (20) days to
                  cure, in which event Tenant's failure to proceed diligently to
                  cure such failure shall constitute an event of default.

10.2     Remedies of Landlord for Default by Tenant. Upon the occurrence of an
         event of default, Landlord shall have the right, then or at any time
         thereafter, and while such event of default shall continue, and in
         addition to and not in lieu of any other remedies, relief or rights
         available to Landlord at law or equity or contained in this Lease, to
         do any of the following:

         10.2.1   Landlord Cure. Landlord by itself or its authorized agents may
                  cure the default and charge Tenant for the costs of such cure,
                  which charge shall be due and payable as rental under this
                  Lease immediately upon written notice to Tenant.

         10.2.2   Distrain. Landlord may distrain for rent due.

         10.2.3   Exercise General Lien. Landlord may exercise its general lien
                  on the leasehold estate and all property in the Leased
                  Premises.

         10.2.4   Right of Re-Entry. Landlord shall have the right to re-enter
                  the Leased Premises to assume and take possession of the whole
                  or any part thereof, and to remove all persons or personal
                  property by direct or summary action, or in a different type
                  of suit or proceeding, by force or otherwise, without being
                  deemed guilty of trespass or other actionable wrong by reason
                  thereof, and without being liable for the damages therefor or
                  in connection therewith, and, after demand made therefor,
                  Tenant or anyone in possession claiming under Tenant shall be
                  deemed guilty of unlawful detainer and subject to such summary
                  or other action as may be provided by law. Additionally,
                  Landlord may relet the Leased Premises as the agent for and in
                  the name of the Tenant, at any rental readily acceptable,
                  applying the proceeds first to the payment of such rent as the
                  same comes due, and toward the fulfillment of the other
                  covenants and agreements of Tenant herein contained, and the
                  balance, if any, shall be paid to Tenant; and the Tenant
                  hereby agrees that if Landlord shall recover or take
                  possession of said Leased Premises as aforesaid and be unable
                  to relet and rent the same so as to realize a sum equal to the
                  rent hereby reserved, Tenant shall pay to Landlord any loss or
                  difference of rent for the remainder of the term.

         10.2.5   Termination of Lease. Landlord, irrespective of the date on
                  which its right of re-entry shall have accrued or be
                  exercised, shall have the


                                     - 14 -
<PAGE>   19
                  right, whether for rent or possession or otherwise, to forfeit
                  this Lease and terminate the state of tenancy hereby created.
                  This right to terminate is exercisable by a written notice to
                  Tenant, which written notice may be part of a notice of
                  default previously delivered to Tenant, and, as such, may be
                  conditioned upon Tenant's failure to cure the default and the
                  event of default. The termination may be made effective as of
                  the event of default or thereafter, and, if not otherwise
                  specified, will be deemed to be effective immediately. Upon
                  such termination and forfeiture, Landlord shall be entitled to
                  and may take immediate possession of the Leased Premises, any
                  other notice or demand being hereby waived. Such termination
                  does not, however, release Tenant from liability for rentals
                  then overdue or remaining under the Lease but shall operate to
                  accelerate the entire balance of the term rental, which shall
                  become immediately due and payable by Tenant, along with all
                  overdue rentals and charges.

10.3     Non-Waiver of Remedies. It is expressly agreed that neither the taking
         of possession of the Leased Premises nor the institution of any
         proceedings by way of unlawful detainer, ejectment, quiet title, or
         otherwise, to secure possession of the Leased Premises, nor the
         re-entry by Landlord with or without the institution of such
         proceedings, nor the rerenting or subletting of the Leased Premises,
         shall operate to terminate this Lease in whole or in part, nor of
         itself constitute an exercise of Landlord's option to do so, but only
         by the giving of the written notice specifically specifying termination
         shall such termination be effected.

         In the event Tenant breaches this Lease, or any covenant, term or
         condition hereunder, and abandons the Leased Premises, this Lease shall
         continue in force and effect for so long as the Landlord does not
         terminate Tenant's right to possession, and Landlord may enforce all
         rights and remedies of Landlord including, without limitation, the
         right to recover rental as it becomes due hereunder. Acts of
         maintenance or preservation or efforts to relet the Leased Premises, or
         the appointment of a receiver upon the initiation of the Landlord to
         protect the Landlord's interest under this Lease shall not constitute a
         termination of Tenant's right to possession.

         Waiver by Landlord of any default, breach or failure of Tenant under
         this Lease shall not be construed as a wavier of any subsequent or
         different default, breach or failure. In case of a breach by Tenant of
         any of the covenants or undertakings of Tenant, Landlord nevertheless
         may accept from Tenant any payments hereunder without in any way
         waiving Landlord's right to exercise the remedies hereinbefore provided
         for by reason of any other breach or lapse which was in existence at
         the time such payment or payments were accepted by Landlord.

         It is expressly understood that the enumeration herein of express
         rights, options and privileges shall not limit Landlord nor deprive
         Landlord of any other remedy or action


                                     - 15 -
<PAGE>   20
         or cause of action by reason of any default of Tenant, including the

            This Schuff Steel Company Supplemental Retirement and Deferred
Compensation Plan (the "Plan") is adopted by Schuff Steel Company (the

of the Internal Revenue Code of 1986, as amended (the "Code"). The Plan is
intended to be a "top-hat" plan (i.e., an unfunded deferred compensation plan
maintained for a select group of management or highly compensated employees)
under Sections 201(2), 301(a)(3), and 401(a)(1) of the Employee Retirement
Income Security Act of 1974 ("ERISA").

            Accordingly, the following Plan is adopted.

            Participation in the Plan is voluntary. In order to participate, an
otherwise Eligible Employee must make written application in such manner as may
be required by the Employer.

            Nothing contained herein shall be construed as a promise or guaranty
by the Employer to any Eligible Employee of continuous employment and each
Eligible Employee shall be deemed an "Employee at Will".

            2.2 RE-EMPLOYMENT. If a Participant whose employment with the
Employer has been terminated is re-employed, he or she shall become a

      allocated under Paragraph 3.2(b) above, shall be allocated among
      Participants' Accounts in such proportions as determined by the Employer,
      in its sole discretion.

            3.3 PERMISSIBLE TYPES OF EMPLOYER CONTRIBUTIONS. Payments on account

            4.1 INVESTMENTS. The amounts allocated to the Participant Accounts
shall be invested by the Trustee in accordance with either the directions of the
Investment Committee or the provisions of the Trust Agreement (as the case may
be).

            4.2 INVESTMENT IN SINGLE FUND AND REASONABLE RULES. The Trustee may
cause all contributions made to it by the Employer and the income therefrom,
without distinction between principal and income, to be held and administered as
a single fund, in which event the Trustee shall not separately invest any share
of any Participant. The Trustee may adopt reasonable rules for the
administration of such common fund and for the determination of the


                                      - 6 -
<PAGE>   8
proportionate interest of each Participant in the fund. In the alternative, the
Trustee may cause contributions made by the Employer and the income therefrom to
be invested in separate shares for any and all Participants, in which event
reasonable rules for the administration of such separate funds shall be adopted
by the Trustee.

            4.3 VALUATION OF ASSETS AND ALLOCATION OF CHANGES. The common fund
assets of the Trust Fund will be valued as of the close of the last day of each
Plan Quarter at their fair market value and the Account of each Participant
shall be adjusted for any net appreciation or net depreciation in the assets of
the common fund portion of the Trust Fund and any net income or loss of the
common fund portion of the Trust Fund for such quarter, with each common fund
portion of the Account being credited or charged in the ratio that the amount of
the Account (as of the close of the last day of the Plan Quarter) bears to the
total (as of the close of the last day of the Plan Quarter) of all remaining
common fund portions of the Accounts. For purposes of such adjustment of
Accounts, any contribution made by the Employer with respect to a Plan Year or
by the Employer during the Plan Quarter shall be considered as having been made
immediately after such valuation and adjustment. In addition to the valuations
required by the first sentence of this Paragraph 4.3, the assets of the Trust
Fund may be valued at such other times during the Plan Year as either the
Trustee or the Investment Committee deems appropriate.

            4.4 ACCOUNTING FOR DISTRIBUTIONS. As of the date of any distribution
hereunder, the distribution to a Participant or his or her Beneficiary or
Beneficiaries shall be charged to such Participant's Account.


                                      - 7 -
<PAGE>   9
            4.5 SEPARATE ACCOUNTS. A separate account under the Plan shall be
established and maintained by the Employer to reflect the Account for each
Participant and to show separately the deemed earnings and losses credited or
debited to such Account.

                              ARTICLE V. - VESTING

            5.1 ACCOUNT VESTING ON DEATH, RETIREMENT OR TOTAL AND PERMANENT
DISABILITY. If a Participant's employment is terminated due to death,
Retirement, or Total and Permanent Disability, one hundred percent (100%) of
such Participant's Account shall vest in the Participant (or in his or her
Beneficiary, as the case may be), and shall be distributed or set aside in
accordance with the provisions of Article VI.

            5.2 ACCOUNT VESTING ON TERMINATION. If a Participant's employment is
terminated for any other reason other than death, Retirement, or Total and
Permanent Disability, the following percentages of the Participant's Account
shall vest in the Participant and shall be distributed to or set aside for such
Participant in accordance with the provisions of Article VI:

</TABLE>

            For purposes of this Paragraph 5.2, a "Service for Vesting" shall
mean a Plan Year during which the Eligible Employee completes not less than one
thousand (1,000) hours of service.


                                      - 8 -
<PAGE>   10
Further, for purposes of this Paragraph 5.2, service will be determined on the
basis of months employed and an Eligible Employee will be credited with one
hundred (100) hours of service for each month (or portion of a month) such
Eligible Employee was employed by the Employer.

            5.3 FORFEITURE TO EMPLOYER FOR CERTAIN ACTS. Notwithstanding
anything contained in this Plan or the Trust to the contrary, including but not
limited to the provisions of Paragraphs 1.15, 3.1, 3.2, 3.2(c), 1.15, 3.1, 3.2,
3.2(c),5.1 and 5.2, a Participant shall forfeit to the Employer any and all
amounts accrued in such Participant's Account if he or she commits any criminal
act or willful or malicious act which damages the Employer or any of its
employees. In this event, a forfeiture shall not be allocated to the remaining
Participants, and shall be made directly to the Employer.

            5.4 CHANGE IN CONTROL. If a Change of Control of the Employer
occurs, one hundred percent (100%) of each Participant's Account shall vest in
each respective Participant and each Participant's Account as of the date of the
Change of Control shall be valued and distributed to or set aside for such
Participant in accordance with the provisions of Article VI. For purposes of
this Paragraph 5.4, a "Change of Control" shall occur when there has been a sale
of substantially all of the assets of the Employer or any person (other than
DAVID A. SCHUFF or a descendant of DAVID A. SCHUFF) obtains ownership or voting
power with respect to or greater than seventy-five percent (75%) of the
aggregate value or voting power, as applicable, of the Employer's capital stock.

                     ARTICLE VI. - DISTRIBUTION OF BENEFITS

            6.1 AMOUNT. A Participant (or his or her Beneficiary) shall become
entitled to receive a distribution in an aggregate amount equal to the vested
portion of the Participant's


                                     - 9 -
<PAGE>   11
Account, on the last day of the Plan Quarter immediately preceding the date of
Participant's termination of employment. Any payment due hereunder from the
Trust which is not paid by the Trust will be paid by the Employer from its
general assets in which case the Employer will be reimbursed by the Trust within
a reasonable period of time as soon as administratively feasible.

            6.2 METHOD OF PAYMENT.

                  (a) Cash Payments. All payments under the Plan shall be made
      in cash or in kind, pursuant to the election of a Participant.

                  (b) Paragraph 5.1 and 5.4 Distributions. In the event a
      Participant becomes entitled to benefits under Paragraph 5.1, an aggregate
      amount equal to the Participant's Account will be paid by the Trust or the
      Employer, as provided by Paragraphs 6.1 and 8.1, in a lump sum, on or
      before thirty (30) days following the date of Participant's termination of
      employment, or in annual installments made over a period selected by the
      Participant, or in the form of an annuity for the life of the Participant
      (or the joint lives of the Participant and his or her spouse) of
      actuarially equivalent value to the Participant's lump sum benefit, as
      selected by the Participant prior to his or her termination of employment.
      If a Participant fails to designate properly the manner of payment of the
      Participant's benefit under the Plan, such payment will be distributed in
      a lump sum within thirty (30) days following the Participant's
      termination.

                  In the case of distributions to a Participant or his or her
      Beneficiary by virtue of an entitlement pursuant to Paragraph 5.4, an
      aggregate amount equal to the Participant's Account will be paid by the
      Trust or the Employer, as provided by Paragraphs 6.1 and 8.1, in a lump
      sum.


                                     - 10 -
<PAGE>   12
                  If the whole or any part of a distribution hereunder is to be
      made in installments, the total to be so paid shall continue to be deemed
      to be invested under such procedures as the Employer may establish, in
      which case, any deemed income, gain, or loss attributable thereto shall be
      reflected in the installment payments, in such equitable manner as the
      Employer shall determine.

                  (c) Paragraph 5.2 Distributions. In the event a Participant
      becomes entitled to benefits under Paragraph 5.2 by reason of a voluntary
      termination of employment, (i.e. resignation) then an amount equal to
      twenty-five percent (25%) of the Participant's Account will be paid by the
      Trust or the Employer as provided in Paragraphs 6.1 and 8.1, in a lump sum
      on or before thirty (30) days following the date of Participant's
      termination of employment and the remaining balance of the Participant's
      Account will be paid in three (3) equal annual installments beginning on
      the one (1) year anniversary of the initial payment required hereunder and
      continuing on the next two (2) successive one (1) year anniversaries
      thereafter. The undistributable portion of the amount payable hereunder
      shall continue to be invested under such procedures as the Employer may
      establish, in which case, any deemed income, gain, or loss attributable
      thereto shall be reflected in the installment payments, in such equitable
      manner as the Employer shall determine.

            6.3 DEATH BENEFITS. If a Participant dies before terminating his or
her employment with the Employer and before the commencement of distributions to
the Participant hereunder, the entire value of the Participant's Account shall
be paid, as provided in Paragraph 6.2(b), to the person or persons designated in
accordance with Paragraph 7.1.

            Upon the death of a Participant after distributions hereunder have
begun but before he or she has received all distributions to which he or she is
entitled under the Plan, the remaining


                                     - 11 -
<PAGE>   13
distributions shall be paid to the person or persons designated in accordance
with Paragraph 7.1, in the manner in which such distributions were payable to
the Participant.

            6.4 WAIVER. Each Eligible Employee acknowledges that computation of
benefits to which he or she may be entitled upon termination of his or her
employment hereunder may take considerable time, particularly in the event that
appraisals may be necessary. Accordingly, each Eligible Employee hereby
expressly waives the statutory requirements of A.R.S. Section 23-353A which
requires an employer to pay wages due an employee by the end of the next regular
pay period or within three (3) working days, if sooner, and the statutory
requirements of A.R.S. Section 23-355 which allows an employee to seek treble
the amount of unpaid wages in a civil action against an employer for unpaid
wages due an employee.

                 ARTICLE VII. - BENEFICIARIES; PARTICIPANT DATA

            7.1 DESIGNATION OF BENEFICIARIES. Each Participant from time to time
may designate any person or persons (who may be named contingently or
successively) to receive such distributions as may be payable under the Plan
upon or after the Participant's death, and such designation may be changed from
time to time by the Participant by filing a new designation. Each designation
will revoke all prior designations by the same Participant, shall be in a form
prescribed by the Employer, and will be effective only when filed in writing
with the Employer during the Participant's lifetime.

            In the absence of a valid beneficiary designation, or if, at the
time any distribution is due to a Beneficiary, there is no living Beneficiary
validly named by the Participant, the Employer shall pay any such distribution
to the Participant's spouse, if then living, but otherwise to the Participant's
then living descendants, if any, per stirpes by right of representation, but, if
none, to the


                                     - 12 -
<PAGE>   14
Participant's estate. In determining the existence or identity of anyone
entitled to a distribution hereunder, the Employer may rely conclusively upon
information supplied by the Participant's personal representative, executor, or
administrator. If a question arises as to the existence or identity of anyone
entitled to receive a distribution, or if a dispute arises with respect to any
such distribution, then, notwithstanding the foregoing, the Employer, in its
sole discretion, may distribute such payment to the Participant's estate without
liability for any tax or other consequences which might flow therefrom, or may
take such other action as the Employer deems to be appropriate.

            7.2 INFORMATION TO BE FURNISHED BY PARTICIPANTS AND BENEFICIARIES;
INABILITY TO LOCATE PARTICIPANTS OR BENEFICIARIES. Any communication, statement,
or notice addressed to a Participant or to a Beneficiary at his or her last post
office address as shown on the Employer's records shall be binding on the
Participant or Beneficiary for all purposes of the Plan. The Employer shall not
be obligated to search for any Participant or Beneficiary beyond the sending of
a certified letter to such last known address. If the Employer notifies any
Participant or Beneficiary that he or she is entitled to an amount under the
Plan and the Participant or Beneficiary fails to claim such amount or make his
or her location known to the Employer within three (3) years thereafter, then,
except as otherwise required by law, if the location of the spouse of the
Participant or one or more of the issue of the Participant is known to the
Employer, the Employer may direct distribution of such amount to the spouse or
any one or more or all of such issue, and in such proportions as the Employer,
in its sole discretion, determines. If the location of none of the foregoing
persons can be determined, the Employer shall have the right, in its sole
discretion, to direct that the amount payable shall be deemed to be a
Forfeiture, except that the dollar amount of the Forfeiture, unadjusted for
deemed gains or losses in the interim, shall be

                                    - 13 -
<PAGE>   15
paid by the Employer if a claim for the benefit subsequently is made by the
Participant or the Beneficiary to whom it was payable within one (1) year of
such Forfeiture. If a benefit payable to an unlocated Participant or Beneficiary
is subject to escheat pursuant to applicable state law, the Employer shall not
be liable to any person for any payment made in accordance with such law.

                 ARTICLE VIII. - COVENANTS OF ELIGIBLE EMPLOYEE

            8.1 NONCOMPETITION. To induce the Employer to adopt this Plan, each
Eligible Employee hereby covenants that during the term of employment and for a
period of thirty-six (36) months after Eligible Employee's termination of
employment with Employer for reasons of employee dishonesty, fraud, wilful
misconduct, criminal conduct, resignation or voluntary cessation of work, each
Eligible Employee will not, either separately, jointly or in association with
others, anywhere within that portion of the United States situated west of the
Mississippi River, establish, engage in, or become interested in, directly or
indirectly, as employee, owner, partner, member, shareholder, guarantor, lender,
consultant, agent, or otherwise, or furnish any information to, work for, or
assist in any manner any person or entity in competing with Employer or any
affiliate of Employer in the business of steel fabrication, erection or detail.
The terms "partner, member, stockholder, co-venturer, lender, provider of
capital, employee, associate or any similar party" shall include, but shall not
be limited to, any person or entity doing business with Employer or any
affiliate of Employer at the time of, or who has done business with Employer or
any affiliate of Employer during the one (1) year period immediately preceding,
Eligible Employee's termination of employment.

            8.2 NON-DISCLOSURE. Each Eligible Employee covenants that he will
not divulge to any competitor, or potential competitor, any of the merchandising
or marketing


                                     - 14 -
<PAGE>   16
techniques, business affairs, business relationship lists, policies, plans,
finances, trade practices, trade secrets, methods, ideas and developments,
software, research techniques, systems or similar information of Employer, with
which Eligible Employee became acquainted during the time Eligible Employee was
associated with Employer.

            8.3 DISCLOSURE. Each Eligible Employee shall disclose promptly to
Employer any and all knowledge of intellectual properties conceived or made by
an Eligible Employee during the term of this Agreement and related to the
business or activities of Employer or any of its affiliates, and hereby assigns
and agrees to execute any instrument or assignment necessary hereafter in order
to assign all of Eligible Employee's interest therein to Employer. The
obligations of an Eligible Employee pursuant to this Paragraph 8.3 shall
continue beyond the termination of Employment with respect to intellectual
properties conceived or made by an Eligible Employee during his employment and
shall be binding upon an Eligible Employee's assigns, executors, administrators
and/or legal representatives.

            8.4 REMEDIES. It is understood by the parties that the covenants
herein contained are for the protection of confidential business information and
business relationships of Employer which are a valuable property right, and that
a breach of any covenant contained in this Agreement would cause substantial
damage to Employer. The parties further agree that damages at law would be an
inadequate remedy for the breach of any of Employee's covenants and that, in
addition to any and all other remedies to which Employer would otherwise be
entitled, Employer shall be entitled to injunctive relief with respect thereto.
Notwithstanding anything contained in this Plan to the contrary, an Employee's
liability for damages to Employer and the Plan by reason of a


                                     - 15 -
<PAGE>   17
breach of Paragraph 6.1, 8,1, shall not exceed the total amount paid or to be
paid Employee under Articles V and VI and above.

            8.5 ENFORCEMENT. Each Eligible Employee and Employer intend that the
covenants of Article VIII shall be deemed a series of separate covenants, one
for each county of each and every state included within the geographical area,
and one for each month of the period specified above. If, in any judicial
proceeding, a court shall refuse to enforce any of such covenants, then such
unenforceable covenants shall be deemed eliminated from the provisions hereof
for the purpose of such proceedings to the extent necessary to permit the
remaining separate covenants to be enforced in such proceedings. If, in any
judicial proceeding, a court shall refuse to enforce any one or more of such
separate covenants because the total time and/or geographical area thereof is
deemed to be excessive or unreasonable, then it is the intent of the parties
hereto that such covenants, which would otherwise be unenforceable due to such
excessive or unreasonable period of time, be enforced for such lesser period of
time and/or geographical area as shall be deemed reasonable and not excessive by
such court.

                             ARTICLE IX. - THE TRUST

            9.1 ESTABLISHMENT OF TRUST. The Employer shall establish the Trust
with the Trustee, pursuant to such terms and conditions as are set forth in the
Trust Agreement attached as Exhibit "A", to be entered into between the Employer
and the Trustee. The Trust is intended to be treated as a "grantor" trust under
the Code, and the establishment of the Trust is not intended to cause
Participants to realize current income on amounts contributed thereto, and the
Trust shall be so interpreted.

                           ARTICLE X. - ADMINISTRATION


                                     - 16 -
<PAGE>   18
            10.1 ADMINISTRATIVE AUTHORITY. Except as otherwise specifically
provided herein, the Employer shall have the sole responsibility for and the
sole control of the operation and administration of the Plan, and shall have the
power and authority to take all action and to make all decisions and
interpretations which may be necessary or appropriate in order to administer and
operate the Plan, including, without limiting the generality of the foregoing,
the power, duty, and responsibility to:

                  (a) Resolve and determine all disputes or questions arising
      under the Plan, including the power to determine the rights of Eligible
      Employees, Participants, and Beneficiaries, and their respective benefits,
      and to remedy any ambiguities, inconsistencies, or omissions in the Plan.

                  (b) Adopt such rules of procedure and regulations as in its
      opinion may be necessary for the proper and efficient administration of
      the Plan and as are consistent with the Plan.

                  (c) Implement the Plan in accordance with its terms and the
      rules and regulations adopted as above.

                  (d) Make determinations with respect to the eligibility of any
      Eligible Employee as a Participant and make determinations concerning the
      crediting and distribution of Plan Accounts.

                  (e) Appoint any persons or firms, or otherwise act to secure
      specialized advice or assistance, as it deems necessary or desirable in
      connection with the administration and operation of the Plan. The Employer
      shall be entitled to rely conclusively upon, and shall be fully protected
      in any action or omission taken by it in good faith reliance upon, the


                                     - 17 -
<PAGE>   19
      advice or opinion of such firms or persons. The Employer shall have the
      power and authority to delegate from time to time by written instrument
      all or any part of its duties, powers, or responsibilities under the Plan,
      both ministerial and discretionary, as it deems appropriate, to any person
      or committee, and in the same manner to revoke any such delegation of
      duties, powers, or responsibilities. Any action of such person or
      committee in the exercise of such delegated duties, powers, or
      responsibilities shall have the same force and effect for all purposes
      hereunder as if such action had been taken by the Employer. Further, the
      Employer may authorize one or more persons to execute any certificate or
      document on behalf of the Employer, in which event any person notified by
      the Employer of such authorization shall be entitled to accept and
      conclusively rely upon any such certificate or document executed by such
      person as representing action by the Employer until such third person
      shall have been notified of the revocation of such authority.

            10.2  INVESTMENT COMMITTEE.

                  (a) The Trust Fund shall be invested by the Trustee as
      directed by an Investment Committee, which shall consist of the President
      of the Employer and three (3) Participants appointed by a majority of all
      Participants, who shall signify in writing their acceptance of such
      appointment. Any member of the Investment Committee may resign upon giving
      written notice to the Participants. Each appointee (other than the
      President of the Employer) shall hold office at the pleasure of the
      Participants. Vacancies arising in the Investment Committee from death,
      resignation or otherwise, shall be filled by the Participants, but the
      Investment Committee may act notwithstanding the existence of the
      vacancies so long as there is at least one (1) member of the Investment
      Committee.


                                     - 18 -
<PAGE>   20
                  At any time the Board of Directors of the Employer may adopt
      the resolution abolishing the Investment Committee and assigning all of
      the duties of the Investment Committee to the Trustee; such resolution
      shall be effective as soon as it is communicated in writing to both the
      Investment Committee and the Trustee, or at such other subsequent
      effective date as provided in the resolution. Whenever such a resolution
      is effective as to the Plan, the term "Trustee" shall be deemed to replace
      the term "Investment Committee." Such a resolution may be rescinded by the
      Board of Directors of the Employer and shall be effective as soon as it is
      communicated in writing to the Trustee, or shall be effective at such
      later date as provided in the resolution.

                  (b) The Investment Committee shall not take any action nor
      direct the Trustee to take any action that would result in benefitting one
      Participant or a group of Participants at the expense of another, or
      discriminating between Participants similarly situated, or applying
      different rules to a substantially similar set of facts.

                  (c) The Investment Committee shall act by a majority (or by
      all members if there be only one or two members) of members constituting
      the Investment Committee at the time of such action, and such action may
      be taken either by vote at a meeting or in writing without a meeting.

                  (d) Except as otherwise provided in the Plan, the Investment
      Committee shall have control of the investment of the Trust Fund of the
      Plan including the common and separate portions thereof, with all powers
      necessary to enable it to carry out its duties in that respect. The
      Investment Committee shall have the right, exercisable at any time by
      delivery to the Trustee of an instrument in writing, to instruct or direct
      the Trustee with respect to the


                                     - 19 -
<PAGE>   21
      investment of the Trust Fund. The Investment Committee may inspect the
      records of the Employer or Trustee whenever such inspection may be
      reasonably necessary in order to determine any fact pertinent to the
      performance of the duties of the Investment Committee. The Investment
      Committee, however, shall not be required to make any inspection, but may,
      in good faith, rely upon any statement of the Trustee or Employer or any
      of its officers or employees.

                  (e) The members of the Investment Committee shall serve
      without compensation for their services.

            10.3  MUTUAL EXCLUSION OF RESPONSIBILITY.  Neither the Trustee nor
the Employer shall be obligated to inquire into or be responsible for any act or
failure to act, or the authority therefor, on the part of the other.

            10.4 UNIFORMITY OF DISCRETIONARY ACTS. Whenever in the
administration or operation of the Plan discretionary actions by the Employer
are required or permitted, such actions shall be consistently and uniformly
applied to all persons similarly situated, and no such action shall be taken
which shall discriminate in favor of any particular person or group of persons.

            10.5 LITIGATION. Except as may be otherwise required by law, in any
action or judicial proceeding affecting the Plan, no Participant or Beneficiary
shall be entitled to any notice or service of process, and any final judgment
entered in such action shall be binding on all persons interested in, or
claiming under, the Plan.

            10.6 PAYMENT OF ADMINISTRATION EXPENSES. All expenses incurred in
the administration and operation of the Plan and the Trust, excluding any taxes
payable by the


                                     - 20 -
<PAGE>   22
Employer or its shareholders in respect of the Plan or Trust, shall be paid by
the Employer. The Plan or Trust shall reimburse the Employer for any taxes
attributable to the earnings of the Trust. Such reimbursement shall be an amount
equal to the combined federal and state income taxes attributable to Trust
earnings, computed at the highest applicable marginal individual federal and
state tax rates in effect for the Plan Year coinciding with or within which the
taxable year of the Employer ends.

            10.7 CLAIMS PROCEDURE. Any person claiming a benefit under the Plan
(a "Claimant") shall present the claim, in writing, to the Employer, and the
Employer shall respond in writing. If the claim is denied, the written notice of
denial shall state, in a manner calculated to be understood by the Claimant: or;

                  (a) The specific reason or reasons for the denial, with
      specific references to the Plan provisions on which the denial is based;

                  (b) A description of any additional material or information
      necessary for the Claimant to perfect his or her claim and an explanation
      of why such material or information is necessary; and

                  (c) An explanation of the Plan's claims review procedure.

            The written notice denying or granting the Claimant's claim shall be
provided to the Claimant within ninety (90) days after the Employer's receipt of
the claim, unless special circumstances require an extension of time for
processing the claim. If such an extension is required, written notice of the
extension shall be furnished by the Employer to the Claimant within the initial
ninety (90) day period and in no event shall such an extension exceed a period
of ninety (90) days from the end of the initial ninety (90) day period. Any
extension notice shall indicate the special circumstances requiring the
extension and the date on which the Employer expects to render a


                                     - 21 -
<PAGE>   23
decision on the claim. Any claim not granted or denied within the period noted
above shall be deemed to have been denied.

            Any Claimant whose claim is denied, or deemed to have been denied
under the preceding sentence (or such Claimant's authorized representative),
may, within sixty (60) days after the Claimant's receipt of notice of the
denial, or after the date of the deemed denial, request a review of the denial
by notice given, in writing, to the Employer. Upon such a request for review,
the claim shall be reviewed by the Employer (or its designated representative),
which may, but shall not be required to, grant the Claimant a hearing. In
connection with the review, the Claimant may have representation, may examine
pertinent documents, and may submit issues and comments in writing.

            The decision on review normally shall be made within sixty (60) days
of the Employer's receipt of the request for review. If an extension of time is
required due to special circumstances, the Claimant shall be notified, in
writing, by the Employer, and the time limit for the decision on review shall be
extended to one hundred twenty (120) days. The decision on review shall be in
writing and shall state, in a manner calculated to be understood by the
Claimant, the specific reasons for the decision and shall include references to
the relevant Plan provisions on which the decision is based. The written
decision on review shall be given to the Claimant within the sixty (60) day (or,
if applicable, the one hundred twenty (120) day) time limit discussed above. If
the decision on review is not communicated to the Claimant within the sixty (60)
day (or, if applicable, the one hundred twenty (120) day) period discussed
above, the claim shall be deemed to have been denied upon review. All decisions
on review shall be final and binding with respect to all concerned parties.

                             ARTICLE XI. - AMENDMENT

            11.1 RIGHT TO AMEND. The Employer, by written instrument executed by
the Employer, shall have the right to amend the Plan, at any time and with
respect to any provisions hereof, and all parties hereto or claiming any
interest hereunder shall be bound by such amendment; provided, however, that no
such amendment shall deprive a Participant or a Beneficiary of a right accrued
hereunder prior to the date of the amendment.

            11.2 AMENDMENTS TO ENSURE PROPER CHARACTERIZATION OF PLAN.
Notwithstanding the provisions of Paragraph 11.1, the Plan and the Trust
Agreement may be amended by the Employer at any time, retroactively if required,
if found necessary, in the opinion of the Employer, in order to ensure that the
Plan is characterized as "top-hat" plan of deferred compensation maintained for
a select group of management or highly compensated employees as described under
ERISA Sections 201(2), 301(a)(3), and 401(a)(1), and to conform the Plan to the
provisions and requirements of any applicable law (including ERISA and the
Code). No such amendment shall be considered prejudicial to any interest of a
Participant or a Beneficiary hereunder.

                           ARTICLE XII. - TERMINATION

            12.1 EMPLOYER'S RIGHT TO TERMINATE OR SUSPEND PLAN. The Employer
reserves the right, at any time, to terminate the Plan and/or its obligation to
make further contributions. The Employer also reserves the right, at any time,
to suspend its obligation to make further contributions for a fixed or
indeterminate period of time.

            12.2 AUTOMATIC TERMINATION OF PLAN. The Plan, but not the Trust,
automatically shall terminate upon the dissolution of the Employer, or upon its
merger into or


                                     - 23 -
<PAGE>   25
consolidation with any other corporation or business organization, if there is a
failure by the surviving corporation or business organization to adopt
specifically and agree to continue the Plan.

            12.3 SUSPENSION OF CONTRIBUTIONS. In the event of a suspension of
the Employer contributions, the Employer shall continue the remaining aspects of
the Plan during the period of the suspension.

            12.4 ALLOCATION AND DISTRIBUTION. This Paragraph 12.4 shall become
operative upon a complete termination of the Plan. The provisions of this
Paragraph 12.4 also shall become operative in the event of a partial termination
of the Plan, as determined by the Employer, but only with respect to that
portion of the Plan attributable to the Participants to whom the partial
termination is applicable. Upon the effective date of any such event,
notwithstanding any other provisions of the Plan, no persons who were not
theretofore Participants shall be eligible to become Participants, the value of
the interest of all Participants and Beneficiaries shall be determined and
become 100% vested and, after deduction of estimated expenses in liquidating
and, if applicable, paying Plan benefits, paid to them as soon as is practicable
after such termination.

            12.5 SUCCESSOR TO EMPLOYER. Any corporation or other business
organization which is a successor to the Employer by reason of a consolidation,
merger, or purchase of substantially all of the assets of the Employer shall
have the right to become a party to the Plan by adopting the same by resolution
of the entity's board of directors or other appropriate governing body. If,
within ninety (90) days from the effective date of such consolidation, merger,
or sale of assets, such new entity does not become a party hereto, as above
provided, the Plan automatically shall be terminated, and the provisions of
Paragraph 12.4 shall become operative.

                         ARTICLE XIII. - MISCELLANEOUS

            13.1 LIMITATIONS ON LIABILITY OF EMPLOYER. Neither the establishment
of the Plan nor any modification thereof, nor the creation of any account under
the Plan, nor the payment of any benefits under the Plan shall be construed as
giving to any Participant or other person any legal or equitable right against
the Employer, or any officer or employer thereof except as provided by law or by
any Plan provision. The Employer does not in any way guarantee any Participant's
Account from loss or depreciation, whether caused by poor investment performance
of an investment or the inability to realize upon an investment due to an
insolvency affecting an investment vehicle or any other reason. In no event
shall the Employer, or any successor, employee, officer, director, or
stockholder of the Employer, be liable to any person on account of any claim
arising by reason of the provisions of the Plan or of any instrument or
instruments implementing its provisions, or for the failure of any Participant,
Beneficiary, or other person to be entitled to any particular tax consequences
with respect to the Plan, or any credit or distribution hereunder.

            13.2 CONSTRUCTION. If any provision of the Plan is held to be
illegal or void, such illegality or invalidity shall not affect the remaining
provisions of the Plan, but shall be fully severable, and the Plan shall be
construed and enforced as if said illegal or invalid provision had never been
inserted herein. For all purposes of the Plan, where the context admits, the
singular shall include the plural, and the plural shall include the singular.
Headings of Articles and Paragraphs herein are inserted only for convenience of
reference and are not to be considered in the construction of the Plan. The laws
of the State of Arizona shall govern, control, and determine all questions of
law arising with respect to the Plan and the interpretation and validity of its
respective provisions, except where those laws are preempted by the laws of the
United States. Participation under the Plan


                                     - 25 -
<PAGE>   27
will not give any Participant the right to be retained in the service of the
Employer nor any right or claim to any benefit under the Plan unless such right
or claim has specifically accrued hereunder.

            The Plan is intended to be and at all times shall be interpreted and
administered so as to qualify as an unfunded deferred compensation plan, and no
provision of the Plan shall be interpreted so as to give any individual any
right in any assets of the Employer which right is greater than the rights of a
general unsecured creditor of the Employer.

            13.3 SPENDTHRIFT PROVISION. No amount payable to a Participant or a
Beneficiary under the Plan will, except as otherwise specifically provided by
law, be subject in any manner to anticipation, alienation, attachment,
garnishment, sale, transfer, assignment (either at law or in equity), levy,
execution, pledge, encumbrance, charge, or any other legal or equitable process,
and any attempt to do so will be void; nor will any benefit be in any manner
liable for or subject to the debts, contracts, liabilities, engagements, or
torts of the person entitled thereto. Further, (i) the withholding of taxes from
Plan benefit payments, (ii) the recovery under the Plan of overpayments of
benefits previously made to a Participant or Beneficiary, (iii) if applicable,
the transfer of benefit rights from the Plan to another plan, or (iv) the direct
deposit of benefit payments to an account in a banking institution (if not
actually part of an arrangement constituting an assignment or alienation) shall
not be construed as an assignment or alienation.

            In the event that any Participant's or Beneficiary's benefits
hereunder are garnished or attached by order of any court, the Employer may
bring an action or a declaratory judgment in a court of competent jurisdiction
to determine the proper recipient of the benefits to be paid under the Plan.
During the pendency of said action, any benefits that become payable shall be
held as credits to the Participant's or Beneficiary's Account or, if the
Employer prefers, paid into the court as they


                                     - 26 -
<PAGE>   28
become payable, to be distributed by the court to the recipient as the court
deems proper at the close of said action.

            IN WITNESS WHEREOF, the Employer has caused the Plan to be executed
effective as of the 1st day of January, 1996.

                                 TRUST AGREEMENT


                                    RECITALS

                  THIS TRUST AGREEMENT is made and entered into effective as of
the 1st day of January, 1996 by and between SCHUFF STEEL COMPANY (the
"Employer"), which sponsors the SCHUFF STEEL COMPANY SUPPLEMENTAL RETIREMENT AND
DEFERRED COMPENSATION PLAN (the "Plan"), and SCOTT SCHUFF (the "Trustee").

                  The Plan provides for the Employer to pay all Plan benefits
from its general revenues and assets. The Employer wishes to establish a trust
fund for the purpose of providing a source from which to pay certain benefits
under the Plan, such trust fund being subject to the claims of the Employer's
creditors in the event of the Employer's bankruptcy or insolvency. Contributions
to the trust fund shall be held by the Trustee and invested, reinvested and
distributed in accordance with the provisions of this Trust Agreement.

                  The Trust established by this Trust Agreement is intended to
be a "grantor trust," with the result that the corpus and income of the Trust
are treated for tax purposes as assets and income of the Employer.

                  NOW, THEREFORE, in consideration of the mutual covenants
contained herein, the Employer and the Trustee, intending to be legally bound,
declare and agree as follows:


                                      - 1 -
<PAGE>   35
                       ARTICLE I. - ESTABLISHMENT OF TRUST

                  1.1 TRUST DEPOSITS. The Employer shall deposit with the
Trustee, in trust (the "Trust"), certain funds, which shall be held,
administered and distributed by the Trustee as provided in this Trust Agreement.

                  1.2 IRREVOCABILITY. The Trust shall be revocable by the
Employer until the occurrence of a Change of Control, at which time the Trust
shall become irrevocable. For purposes hereof, a "Change of Control" shall be
deemed to occur when there is a sale of substantially all of the assets of the
Employer or when any person (other than David A. Schuff or a descendant of David
A. Schuff) acquires, directly or indirectly, greater than seventy-five percent
(75%) of the aggregate voting power over Schuff Steel Company's voting stock.

                  1.3 GRANTOR TRUST. The Trust is intended to be a grantor
trust, of which the Employer is the grantor, within the meaning of sub-part E,
part 1, subchapter J, chapter 1, subtitle A of the Internal Revenue Code of
1986, as amended, and shall be construed accordingly.

                  1.4 PLAN ASSETS. The principal of the Trust, and any earnings
thereon, shall be held separate and apart from other funds of the Employer and
shall be used exclusively for the uses and purposes of the Plan and general

interest in, any assets of the Trust. Any rights created under the Plan, and

                  1.5 ACCEPTANCE OF TRUST. The Trustee accepts the Trust
established under the Trust Agreement on the terms and subject to the provisions

all of the duties and obligations imposed upon it under this Trust Agreement.

                  ARTICLE II. - PLAN AS PART OF TRUST AGREEMENT

                  2.1 INCORPORATION BY REFERENCE. The Plan is expressly
incorporated herein and made a part hereof with the same force and effect as if
the Plan had been fully set forth herein. A copy of the Plan has been delivered
to the Trustee. All capitalized terms defined in the Plan shall have the same
meanings when used herein unless expressly provided to the contrary herein. The
Employer shall deliver to the Trustee copies of all amendments to the Plan made
after the date of this Trust Agreement.

                  2.2 BENEFIT PROVISIONS. The terms of the Plan shall govern the
amount, form and timing of benefit payments under the Plan to which a Plan
Participant or Beneficiary is entitled.

                  2.3 AMENDMENT OF PLAN. The incorporation of the Plan into this
Trust Agreement shall not affect the provisions of the Plan concerning the
amendment or termination thereof.

         ARTICLE III. - PAYMENTS TO PLAN PARTICIPANTS AND BENEFICIARIES

                  3.1 PAYMENT DIRECTION AND TAXES. The Employer shall deliver to
the Trustee a statement (the "Payment Direction") that indicates the amounts
payable (net of payroll taxes and withholding) in respect to any Plan
Participant who becomes entitled to receive a distribution from the Plan (or his
or her Beneficiaries), which distribution is a benefit for which the


                                      - 3 -
<PAGE>   37
Employer has made contributions to the Trust, and that provides the time for the
payment of such amounts. Except as otherwise provided herein, the Trustee shall
make payments to a Plan Participant or his or her Beneficiaries in accordance
with such Payment Direction. The Employer shall make provision for the reporting
and withholding of any federal, state or local taxes that may be required to be
withheld with respect to the payment of benefits pursuant to the terms of the
Plan and shall remit such amounts withheld to the appropriate taxing
authorities.

                  3.2 ENTITLEMENT TO BENEFITS. The entitlement of a Plan
Participant or his or her Beneficiaries to benefits under the Plan shall be as
set forth in the Plan, and any claim for such benefits shall be considered and
reviewed under the procedures set out in the Plan.

                  3.3 PAYMENTS BY EMPLOYER. The Employer may make payment of
benefits directly to the Plan Participant or his or her Beneficiaries as they
become due under the terms of the Plan. The Employer shall notify the Trustee of
its decision to make payment of benefits directly prior to the time amounts are
payable to a Plan Participant or his or her Beneficiaries.

         ARTICLE IV. - TRUSTEE RESPONSIBILITY WHEN EMPLOYER IS INSOLVENT

                  4.1 CESSATION OF PAYMENTS ON EMPLOYER INSOLVENCY. The Trustee
shall cease payment of benefits to the Plan Participant or his or her
Beneficiaries if the Employer is Insolvent. The Employer shall be considered
"Insolvent" for purposes of this Trust Agreement if (i) the Employer is unable
to pay its debts as they become due, or (ii) the Employer is subject to a
pending proceeding as a debtor under the United States Bankruptcy Code.

                  4.2 CLAIMS OF CREDITORS. At all times during the continuance
of this Trust, the principal and income of the Trust shall be subject to claims
of general creditors of the Employer under federal and state law as set forth
below.


                                      -4-
<PAGE>   38

                  (a) The Board of Directors and the chief executive officer of
         the Employer shall have the duty to inform the Trustee in writing of
         the Employer's Insolvency. If a person claiming to be a creditor of the
         Employer alleges in writing to the Trustee that the Employer has become
         Insolvent, the Trustee shall determine whether the Employer is
         Insolvent and, pending such determination, the Trustee shall
         discontinue payment of benefits to Plan Participants and Beneficiaries.

                  (b) Unless the Trustee has actual knowledge of the Employer's
         Insolvency, or has received notice from the Employer or a person
         claiming to be a creditor alleging that the Employer is Insolvent, the
         Trustee shall have no duty to inquire whether the Employer is
         Insolvent. The Trustee may in all events rely on such evidence
         concerning the Employer's solvency as may be furnished to the Trustee
         and that provides the Trustee with a reasonable basis for making a
         determination concerning the Employer's solvency.

                  (c) If at any time the Trustee has determined that the
         Employer is Insolvent, the Trustee shall discontinue payments to Plan
         Participants and Beneficiaries and shall hold the assets of the Trust
         for the benefit of the Employer's general creditors. Nothing in this
         Trust Agreement shall in any way diminish any rights of any Plan
         Participant or Beneficiary to pursue his or her rights as a general
         creditor of the Employer with respect to benefits due under the Plan or
         otherwise.

                  (d) The Trustee shall resume the payment of benefits to the
         Plan Participants and Beneficiaries in accordance with the terms of
         this Trust Agreement only after the Trustee has determined that the
         Employer is not Insolvent (or is no longer Insolvent).

                      (e) Except as provided herein and in Paragraph 12.2, the
         Employer shall have no right or power to direct the Trustee to return
         to the Employer or to divert to others any of the Trust assets before
         all payments of benefits have been made to all Plan Participants and
         Beneficiaries (or to the Employer, in the case of a Forfeiture of a
         Participant's benefit upon a termination of employment which results in
         a Forfeiture under the terms of the Plan or the inability to locate a
         payee under the terms of the Plan) pursuant to the terms of the Plan.

                        ARTICLE V. - INVESTMENT AUTHORITY

         and preferred stocks, mortgages, debentures, bonds, notes or other
         evidences of indebtedness, and other forms of securities, including
         those issued by the Employer; provided, however, that no stock,

         pledge or lease of the property of any corporation, company or
         association, any of the securities which may at any time be held by it,
         and to do any act with reference thereto, including the exercise of
         options, the making of agreements or subscriptions and the payment of
         expenses, assessments or subscriptions, which may be deemed necessary
         or advisable in connection therewith and to hold and retain any
         securities which it may so acquire.

                  (d) To vote, personally or by general or limited proxy, any
         securities which may be held by it at any time and, similarly, to

         name or in the name of a nominee, or in any form permitting title to

         in units of participation in one or more common, collective or
         commingled trust funds that may be established and maintained by the
         Trustee. Any such common, collective or commingled trust fund may be
         specifically designated for investment in guaranteed investment
         contracts.

                      (h) To invest any part or all of the Trust (including cash

                              SCHUFF STEEL COMPANY

                             1997 STOCK OPTION PLAN


        1. PURPOSE OF THE PLAN. The purpose of this 1997 Stock Option Plan, as
amended (the "Plan"), of Schuff Steel Company, an Arizona corporation
("Company"), is to provide the Company with a means of attracting and retaining
the services of highly motivated and qualified directors and key personnel. The
Plan is intended to advance the interests of the Company by affording to
directors and key employees, upon whose skill, judgment, initiative and efforts
the Company is largely dependent for the successful conduct of its business, an
opportunity for investment in the Company and the incentives inherent in stock
ownership in the Company. In addition, the Plan contemplates the opportunity for
investment in the Company by employees of companies that do business with the
Company. For purposes of this Plan, the term Company shall include subsidiaries,
if any, of the Company.

        2. LEGAL COMPLIANCE. It is the intent of the Plan that all options
granted under it ("Options") shall be either "Incentive Stock Options" ("ISOs"),
as such term is defined in Section 422 of the Internal Revenue Code of 1986, as
amended ("Code"), or non-qualified stock options ("NQOs"); provided, however,
ISOs shall be granted only to employees of the Company. An Option shall be
identified as an ISO or an NQO in writing in the document or documents
evidencing the grant of the Option. All Options that are not so identified as
ISOs are intended to be NQOs. In addition, the Plan provides for the grant of
NQOs to employees of companies that do business with the Company. It is the
further intent of the Plan that it conform in all respects with the requirements
of Rule 16b-3 of the Securities and Exchange Commission under the Securities
Exchange Act of 1934, as amended ("Rule 16b-3"). To the extent that any aspect
of the Plan or its administration shall at any time be viewed as inconsistent
with the requirements of Rule 16b-3 or, in connection with ISOs, the Code, such
aspect shall be deemed to be modified, deleted or otherwise changed as necessary
to ensure continued compliance with such provisions.

        3. ADMINISTRATION OF THE PLAN.

               3.1 PLAN COMMITTEE. The Plan shall be administered by the Board
of Directors (the "Board") until such time as the board appoints a committee
("Committee"). The members of the Committee shall be appointed from time to time
by the Board and shall consist of not less than two (2) persons, each of whom
shall qualify as a "non-employee director" under Rule 16b-3. Such persons shall
be directors of the Company. All references herein to the "Committee" shall
include the Board prior to the time that a Committee is appointed or at any time
thereafter that the Board is authorized to act in accordance with this Plan.

               3.2 GRANTS OF OPTIONS BY THE COMMITTEE. In accordance with the
provisions of the Plan, the Committee, by resolution, shall select those
eligible persons to whom Options shall be granted ("Optionees"); shall determine
the time or times at which each Option shall be granted, whether an Option is an
ISO or an NQO and the number of shares to be subject to each Option; and shall
fix the time and manner in which the Option may be exercised, the Option
exercise
<PAGE>   2
price, and the Option period. The Committee shall determine the form of option
agreement to evidence the foregoing terms and conditions of each Option, which
need not be identical, in the form provided for in SECTION 7. Such option
agreement may include such other provisions as the Committee may deem necessary
or desirable consistent with the Plan, the Code and Rule 16b-3.

               3.3 COMMITTEE PROCEDURES. The Committee from time to time may
adopt such rules and regulations for carrying out the purposes of the Plan as it
may deem proper and in the best interests of the Company. The Committee shall
keep minutes of its meetings and records of its actions. A majority of the
members of the Committee shall constitute a quorum for the transaction of any
business by the Committee. The Committee may act at any time by an affirmative
vote of a majority of those members voting. Such vote may be taken at a meeting
(which may be conducted in person or by any telecommunication medium) or by
written consent of Committee members without a meeting.

               3.4 FINALITY OF COMMITTEE ACTION. The Committee shall resolve all
questions arising under the Plan and option agreements entered into pursuant to
the Plan. Each determination, interpretation, or other action made or taken by
the Committee shall be final and conclusive and binding on all persons,
including, without limitation, the Company, its shareholders, the Committee and
each of the members of the Committee, and the directors, officers and employees
of the Company, including Optionees and their respective successors in interest.

               3.5 NON-LIABILITY OF COMMITTEE MEMBERS. No Committee member shall
be liable for any action or determination made by him or her in good faith with
respect to the Plan or any Option granted under it.

        4. BOARD POWER TO AMEND, SUSPEND, OR TERMINATE THE PLAN. The Board may,
from time to time, make such changes in or additions to the Plan as it may deem
proper and in the best interests of the Company and its shareholders. The Board
may also suspend or terminate the Plan at any time, without notice, and in its
sole discretion. Notwithstanding the foregoing, no such change, addition,
suspension, or termination by the Board shall (i) materially impair any Option
previously granted under the Plan without the express written consent of the
optionee; or (ii) be undertaken without shareholder approval if such shareholder
approval is required by applicable law or regulation.

        5. SHARES SUBJECT TO THE PLAN. For purposes of the Plan, the Committee
is authorized to grant Options for up to 600,000 shares of the Company's common
stock ("Common Stock"), or the number and kind of shares of stock or other
securities which, in accordance with SECTION 13, shall be substituted for such
shares of Common Stock or to which such shares shall be adjusted. The Committee
is authorized to grant Options under the Plan with respect to such shares. Any
or all unsold shares subject to an Option which for any reason expires or
otherwise terminates (excluding shares returned to the Company in payment of the
exercise price for additional shares) may again be made subject to grant under
the Plan.


                                        2
<PAGE>   3
        6. OPTIONEES. Options shall be granted only to officers, directors or
key employees of the Company or employees of companies that do business with the
Company designated by the Committee from time to time as Optionees. Any Optionee
may hold more than one option to purchase Common Stock, whether such option is
an Option held pursuant to the Plan or otherwise. An Optionee who is an employee
of the Company ("Employee Optionee") and who holds an Option must remain a
continuous full or part-time employee of the Company from the time of grant of
the Option to him until the time of its exercise, except as provided in SECTION
10.3.

        7. GRANTS OF OPTIONS. The Committee shall have the sole discretion to
grant Options under the Plan and to determine whether any Option shall be an ISO
or an NQO, except that any Options granted to members of the Committee shall be
granted by the Board. The terms and conditions of Options granted under the Plan
may differ from one another as the Committee, in its absolute discretion, shall
determine as long as all Options granted under the Plan satisfy the requirements
of the Plan. Upon determination by the Committee that an Option is to be granted
to an Optionee, a written option agreement evidencing such Option shall be given
to the Optionee, specifying the number of shares subject to the Option, the
Option exercise price, whether the Option is an ISO or an NQO, and the other
individual terms and conditions of such Option. Such option agreement may
incorporate generally applicable provisions from the Plan, a copy of which shall
be provided to all Optionees at the time of their initial grants under the Plan
or within a reasonable period of time thereafter. The Option shall be deemed
granted as of the date specified in the grant resolution of the Committee, and
the option agreement shall be dated as of the date of such resolution.
Notwithstanding the foregoing, unless the Committee consists solely of
non-employee directors under Rule 16b-3, any Option granted to an executive
officer, director or 10% beneficial owner for purposes of Section 16 of the
Securities Exchange Act of 1934, as amended ("Section 16 of the 1934 Act"),
shall either be (a) conditioned upon the Optionee's agreement not to sell the
shares of Common Stock underlying the Option for at least six (6) months after
the date of grant or (b) approved by the entire Board or by the shareholders of
the Company. Notwithstanding the above and subject to adjustment as provided in
Section 13, the number of shares subject to options that may be granted to any
one Optionee under this Plan shall be limited to 300,000.

        8. OPTION EXERCISE PRICE. The price per share to be paid by the Optionee
at the time an ISO is exercised shall not be less than one hundred percent
(100%) of the Fair Market Value (as hereinafter defined) of one share of the
optioned Common Stock on the date on which the Option is granted. No ISO may be
granted under the Plan to any person who, at the time of such grant, owns
(within the meaning of Section 424(d) of the Code) stock possessing more than
ten percent (10%) of the total combined voting power of all classes of stock of
the Company or of any parent thereof, unless the exercise price of such ISO is
at least equal to one hundred and ten percent (110%) of Fair Market Value on the
date of grant. The price per share to be paid by the Optionee at the time an NQO
is exercised shall be determined by the Committee. For purposes of the Plan, the
"Fair Market Value" of a share of the Company's Common Stock as of a given date
shall be: (i) the closing price of a share of the Company's Common Stock on the
principal exchange on which shares of the Company's Common Stock are then
trading, if any, on the day immediately preceding such date, or, if shares were
not traded on such date, then on the next preceding trading day during which a
sale occurred; or (ii) if the Company's Common Stock is not traded on an
exchange but is quoted on Nasdaq or a successor quotation system, (1) the last
sales price (if the Common Stock is then


                                        3
<PAGE>   4
listed as a National Market Issue under the Nasdaq National Market System) or
(2) the closing representative bid price (in all other cases) for the Common
Stock on the day immediately preceding such date as reported by Nasdaq or such
successor quotation system; or (iii) if the Company's Common Stock is not
publicly traded on an exchange and not quoted on Nasdaq or a successor quotation
system, the closing bid price for the Common Stock on such date as determined in
good faith by the Committee; or (iv) if the Company's Common Stock is not
publicly traded, the fair market value established by the Committee acting in
good faith. In addition, with respect to any ISO, the Fair Market Value on any
given date shall be determined in a manner consistent with any regulations
issued by the Secretary of the Treasury for the purpose of determining fair
market value of securities subject to an ISO plan under the Code.

        9. CEILING OF ISO GRANTS. The aggregate Fair Market Value (determined at
the time any ISO is granted) of the Common Stock with respect to which an
Optionee's ISOs, together with incentive stock options granted under any other
plan of the Company and any parent, are exercisable for the first time by such
Optionee during any calendar year shall not exceed $100,000. If an Optionee
holds such incentive stock options that become first exercisable (including as a
result of acceleration of exercisability under the Plan) in any one year for
shares having a Fair Market Value at the date of grant in excess of $100,000,
then the most recently granted of such ISOs, to the extent that they are
exercisable for shares having an aggregate Fair Market Value in excess of such
limit, shall be deemed to be NQOs. In addition, the maximum number of shares
under this Plan available for grant as ISOs shall be 600,000.

        10. DURATION, EXERCISABILITY, AND TERMINATION OF OPTIONS.

               10.1 OPTION PERIOD. The option period shall be determined by the
Committee with respect to each Option granted. In no event, however, may the
option period exceed ten (10) years from the date on which the Option is
granted, or five (5) years in the case of a grant of an ISO to an Optionee who
is a ten percent (10%) shareholder at the date on which the Option is granted as
described in SECTION 8.

               10.2 EXERCISABILITY OF OPTIONS. Each Option shall be exercisable
in whole or in consecutive installments, cumulative or otherwise, during its
term as determined in the discretion of the Committee; provided, however, that
no Option shall be exercised or exercisable prior to five (5) years from the
date of grant unless the Company shall have consummated an initial public
offering of the Company's Common Stock pursuant to an effective registration
statement under the Securities Act of 1933, as amended (an "IPO") prior to the
expiration of such five (5) year period.

               10.3 TERMINATION OF OPTIONS DUE TO TERMINATION OF EMPLOYMENT,
DISABILITY, OR DEATH OF OPTIONEE. All Options granted under the Plan to any
Employee Optionee shall terminate and may no longer be exercised if the Employee
Optionee ceases, at any time during the period between the grant of the Option
and its exercise, to be an employee of the Company; provided, however, that the
Committee may, in the exercise of its discretion, extend the date to exercise
any Option to a date that extends beyond the date the Optionee terminates
employment with the Company. Notwithstanding the foregoing, (i) if the Employee
Optionee's employment terminates due to disability (as defined in Section
22(e)(3) of the Code and subject to such proof of


                                        4
<PAGE>   5
disability as the Committee may require), such Option may be exercised by the
Employee Optionee (or by his guardian(s), or conservator(s), or other legal
representative(s)) before the earlier of the expiration of twelve (12) months
after such termination or the expiration of the Option (to the extent that the
Option was exercisable by him on the date of the termination of his employment);
or (ii) in the event of the Employee Optionee's death, an Option exercisable by
him at the date of his death shall be exercisable by his legal
representative(s), legatee(s), or heir(s), or by his beneficiary or
beneficiaries so designated by him, as the case may be, within the earlier of
twelve (12) months after his death or the expiration of the Option (to the
extent that the Option was exercisable by him on the date of his death).

        11. MANNER OF OPTION EXERCISE; RIGHTS AND OBLIGATIONS OF OPTIONEES.

               11.1 WRITTEN NOTICE OF EXERCISE. An Optionee may elect to
exercise an Option in whole or in part, from time to time, subject to the terms
and conditions contained in the Plan and in the agreement evidencing such
Option, by giving written notice of exercise to the Company at its principal
executive office.

               11.2 CASH PAYMENT FOR OPTIONED SHARES. If an Option is exercised
for cash, such notice shall be accompanied by a cashier's or personal check, or
money order, made payable to the Company for the full exercise price of the
shares purchased.

               11.3 STOCK SWAP FEATURE. At the time of the Option exercise, and
subject to the discretion of the Committee to accept payment in cash only, the
Optionee may determine whether the total purchase price of the shares to be
purchased shall be paid solely in cash or by transfer from the Optionee to the
Company of previously acquired shares of Common Stock, or by a combination
thereof. If the Optionee elects to pay the total purchase price in whole or in
part with previously acquired shares of Common Stock, the value of such shares
shall be equal to their Fair Market Value on the date of exercise, determined by
the Committee in the same manner used for determining Fair Market Value at the
time of grant for purposes of SECTION 8.

               11.4 INVESTMENT REPRESENTATION FOR NON-REGISTERED SHARES AND
LEGALITY OF ISSUANCE. The receipt of shares of Common Stock upon the exercise of
an Option shall be conditioned upon the Optionee (or any other person who
exercises the Option on his or her behalf as permitted by SECTION 10.3)
providing to the Committee a written representation that, at the time of such
exercise, it is the intent of such person(s) to acquire the shares for
investment only and not with a view toward distribution. The certificate for
unregistered shares issued for investment shall be restricted by the Company as
to transfer unless the Company receives an opinion of counsel satisfactory to
the Company to the effect that such restriction is not necessary under then
pertaining law. The providing of such representation and such restrictions on
transfer shall not, however, be required upon any person's receipt of shares of
Common Stock under the Plan in the event that, at the time of grant of the
Option relating to such receipt or upon such receipt, whichever is the
appropriate measure under applicable federal or state securities laws, the
shares subject to the Option shall be (i) covered by an effective and current
registration statement under the Securities Act of 1933, as amended, and (ii)
either qualified or exempt from qualification under applicable state securities
laws. The Company shall, however, under no circumstances be required to sell or
issue


                                        5
<PAGE>   6
any shares under the Plan if, in the opinion of the Committee, (i) the issuance
of such shares would constitute a violation by the Optionee or the Company of
any applicable law or regulation of any governmental authority, or (ii) the
consent or approval of any governmental body is necessary or desirable as a
condition of, or in connection with, the issuance of such shares.

               11.5 SHAREHOLDER RIGHTS OF OPTIONEE. Upon exercise, the Optionee
(or any other person who exercises the Option on his behalf as permitted by
SECTION 10.3) shall be recorded on the books of the Company as the owner of the
shares, and the Company shall deliver to such record owner one or more duly
issued stock certificates evidencing such ownership. No person shall have any
rights as a shareholder with respect to any shares of Common Stock covered by an
Option granted pursuant to the Plan until such person shall have become the
holder of record of such shares. Except as provided in SECTION 13, no
adjustments shall be made for cash dividends or other distributions or other
rights as to which there is a record date preceding the date such person becomes
the holder of record of such shares.

               11.6 HOLDING PERIODS FOR TAX PURPOSES. The Plan does not provide
that an Optionee must hold shares of Common Stock acquired under the Plan for
any minimum period of time. Optionees are urged to consult with their own tax
advisors with respect to the tax consequences to them of their individual
participation in the Plan.

        12. SUCCESSIVE GRANTS. Successive grants of Options may be made to any
Optionee under the Plan.

        13. ADJUSTMENTS.

               (a) Except as provided herein, if the outstanding Common Stock
shall be hereafter increased or decreased, or changed into or exchanged for a
different number or kind of shares or other securities of the Company or of
another corporation, by reason of a recapitalization, reclassification,
reorganization, merger, consolidation, share exchange, or other business
combination in which the Company is the surviving parent corporation, stock
split-up, combination of shares, or dividend or other distribution payable in
capital stock or rights to acquire capital stock, appropriate adjustment shall
be made by the Committee in the number and kind of shares for which options may
be granted under the Plan. In addition, the Committee shall make appropriate
adjustment in the number and kind of shares as to which outstanding and
unexercised options shall be exercisable, to the end that the proportionate
interest of the holder of the option shall, to the extent practicable, be
maintained as before the occurrence of such event. Such adjustment in
outstanding options shall be made without change in the total price applicable
to the unexercised portion of the option but with a corresponding adjustment in
the exercise price per share.

               (b) In the event of the dissolution or liquidation of the
Company, any outstanding and unexercised options shall terminate as of a future
date to be fixed by the Committee; provided, however, that the Committee shall
accelerate the exercisability of such options and shall give each Optionee at
least 30 days to exercise such options prior to their termination.

               (c) In the event of a Reorganization (as hereinafter defined),
then,


                                        6
<PAGE>   7
                      (i) If there is no plan or agreement with respect to the
Reorganization ("Reorganization Agreement"), or if the Reorganization Agreement
does not specifically provide for the adjustment, change, conversion, or
exchange of the outstanding and unexercised options for cash or other property
or securities of another corporation, then any outstanding and unexercised
options shall terminate as of a future date to be fixed by the Committee;
provided, however, that the Committee shall accelerate the exercisability of
such options and shall give each Optionee at least 30 days to exercise such
options prior to their termination; or

                      (ii) If there is a Reorganization Agreement, and the
Reorganization Agreement specifically provides for the adjustment, change,
conversion, or exchange of the outstanding and unexercised options for cash or
other property or securities of another corporation, then the Committee shall
adjust the shares under such outstanding and unexercised options, and shall
adjust the shares remaining under the Plan which are then available for the
issuance of options under the Plan if the Reorganization Agreement makes
specific provisions therefor, in a manner not inconsistent with the provisions
of the Reorganization Agreement for the adjustment, change, conversion, or
exchange of such options and shares.

               (d) The term "Reorganization" as used in this SECTION 13 shall
mean any reorganization, merger, consolidation, share exchange, or other
business combination pursuant to which the Company is not the surviving parent
corporation after the effective date of the Reorganization, or any sale or
lease of all or substantially all of the assets of the Company.

               (e) The Committee shall provide to each optionee then holding an
outstanding and unexercised option not less than thirty (30) calendar days'
advanced written notice of any date fixed by the Committee pursuant to this
SECTION 13 and of the terms of any Reorganization Agreement providing for the
adjustment, change, conversion, or exchange of outstanding and unexercised
options.

                   Any adjustment to any outstanding ISO pursuant to this 
SECTION 13, if made by reason of a transaction described in Section 424(a) of
the Code, shall be made so as to conform to the requirements of that Section and
the regulations thereunder. If any other transaction described in Section 424(a)
of the Code affects the Common Stock subject to any unexercised ISO theretofore
granted under the Plan (hereinafter for purposes of this SECTION 13 referred to
as the "old option"), the Board of Directors of the Company or of any surviving
or acquiring corporation may take such action as it deems appropriate, in
conformity with the requirements of that Code Section and the regulations
thereunder, to substitute a new option for the old option, in order to make the
new option, as nearly as may be practicable, equivalent to the old option, or to
assume the old option.

               (f) All adjustments and determinations under this SECTION 13
shall be made by the Committee in good faith in its sole discretion.

        14. CONTINUED EMPLOYMENT. Neither the creation of the Plan nor the
granting of Option(s) under it shall be deemed to create a right in an Employee
Optionee to continued employment with the Company, and each such Employee
Optionee shall be and shall remain subject to discharge by the Company as though
the Plan had never come into existence.


                                        7
<PAGE>   8
        15. TAX WITHHOLDING. The exercise of any Option granted under the Plan
is subject to the condition that if at any time the Company shall determine, in
its discretion, that the satisfaction of withholding tax or other withholding
liabilities under any federal, state or local law is necessary or desirable as a
condition of, or in connection with, such exercise or a later lapsing of time or
restrictions on or disposition of the shares of Common Stock received upon such
exercise, then in such event, the exercise of the Option shall not be effective
unless such withholding shall have been effected or obtained in a manner
acceptable to the Company. When an Optionee is required to pay to the Company an
amount required to be withheld under applicable income tax laws in connection
with the exercise of any Option, the Committee may require the Optionee to
satisfy the obligation, in whole or in part, by withholding shares of Common
Stock having a value equal to the amount required to be withheld. The value of
the Common Stock withheld pursuant to the election shall be determined by the
Committee, in accordance with the criteria set forth in SECTION 8, with
reference to the date the amount of tax to be withheld is determined. The

                                    RECITALS

        A. The Company has adopted the Schuff Steel Company 1997 Stock Option
Plan, as amended (the "Plan"), as an incentive to attract and retain key 
employees, officers and directors whose services are considered unusually 
valuable by providing an opportunity to have a proprietary interest in the 
success of the Company; and

        B. The Company's Board of Directors (the "Board") believes that the
granting of the Option herein described to Employee is consistent with the
stated purposes for which the Plan was adopted;

        NOW, THEREFORE, in consideration of the mutual covenants and conditions
hereinafter set forth and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the Company and Employee agree
as follows:

        1. Grant of Option. The Company hereby grants to the Employee the right

___________________________ shares (such number being subject to adjustment as
provided in Section 13 of the Plan) of the common stock of the Company (the
"Stock") on the terms and conditions set forth herein and in the Plan. This 
Option may be exercised in whole or in part and from time to time as 
hereinafter provided.

        The Option granted under this Agreement is intended to qualify as an
"incentive stock option" under Section 422 of the Internal Revenue Code of 1986,
as amended.

        2. Vesting. All of the Options granted hereunder shall vest sixty (60)
months after the Date of Grant, except that, in the event the Company

        of Grant;

        Date of Grant; and

               (e) ________ shares shall vest sixty (60) months after the Date
        of Grant.


        3. Purchase Price. The price at which the Employee shall be entitled to
purchase the Stock covered by the Option shall be $_________ per share (the Fair
Market Value on the Date of Grant).

termination as provided herein or in the Plan.

        5. Exercise of Option. The Option may be exercised by Employee as to all

exercised by Employee by delivery to the Company of written notice of exercise
and payment of the purchase price as provided in Sections 7 and 8 hereof.

defined in the Plan) of all shares of Stock with respect to which the Option is
first exercisable by the Employee in any calendar year may not exceed $100,000.
To the extent such limitation is for any reason exceeded, the amount in excess

persons other than Employee pursuant to the terms of this option agreement or
the Plan, such notice shall be signed by such other person or persons and shall
be accompanied by proof acceptable to the Company of the legal right of such
person or persons to exercise the Option. All shares of Stock delivered by the

        9. Confidentiality and Nondisclosure Agreement.

               (a) Employee hereby acknowledges and agrees that in the course of
        Employee's employment with the Company, Employee has and will become
        acquainted with Company Confidential Information (as defined in
        subsection (b) of this Section 9), and that Company Confidential
        Information has been developed at great expense to the Company, is
        proprietary to the Company, and is and shall remain the exclusive
        property of the Company. Accordingly, for and in consideration for the
        Options granted hereunder, and other good and valuable consideration,
        Employee hereby agrees that (i) Employee will not, without the express
        written consent of the Company, during Employee's employment with the
        Company or at any time thereafter (or until such time as Company
        Confidential Information becomes generally known, or readily
        ascertainable by proper means, by persons unrelated to the Company),
        disclose to others, copy, make any use of, or remove from the Company's
        premises any Company Confidential Information, except as Employee's
        duties for the Company may specifically require; (ii) in the event of
        dispute or litigation, Employee shall have the burden of proof by clear
        and convincing evidence that the Company Confidential Information has
        become generally known, or readily ascertainable by proper means, by
        persons unrelated to the Company; and (iii) upon termination of
        employment, Employee shall promptly deliver to the Company the originals
        and all copies of any and all materials, documents, notes, manuals, or
        lists containing or embodying Company Confidential Information, or
        relating directly or indirectly to the Company's business, in the
        possession or control of the Employee. In the event Employee violates
        this Section 9, the Options granted to Employee hereunder shall lapse
        immediately upon and at the time of such violation, regardless of
        whether Company shall then have knowledge of such violation or whether
        Employee's employment shall have then been terminated.

               (b) For purposes of this Section 9, "Company Confidential
        Information" shall include, without limitation, the following
        information which is the confidential, proprietary information, and
        trade secrets of the Company: (i) customer lists, consultant lists, and
        customer information as compiled by the Company, including customer
        orders, product or service usage, product or service volumes, pricing,

        expirations, and other compiled customer information; (ii) the Company's

        including sources and costs; (v) information relating to designs,
        formulas, developmental or experimental work, know-how, products,
        processes, computer programs, source codes, data bases, designs,


                                       -3-
<PAGE>   4
        schematics, inventions, creations, original works of authorship, or
        other subject matter related to the Company's business, research and
        development, strategic planning, manufacturing, engineering, fabrication
        or erection operations, purchasing, finance, marketing, promotion,
        distribution, licensing, and selling activities, whether now existing,
        or acquired, developed, or made available anytime in the future to the
        Company; (vi) all information which Employee has a reasonable basis to
        consider confidential or which is treated by the Company as
        confidential; and (vii) any and all information having independent
        economic value to the Company that is not generally known to, and not
        readily ascertainable by proper means by, persons who can obtain
        economic value from its disclosure or use. Employee acknowledges that
        such information is Company Confidential Information whether disclosed
        to or learned by Employee or originated by Employee during employment by
        the Company. In case of doubt, all information about the Company shall
        be presumed to be confidential.

               (c) Employee agrees that damages cannot compensate Company in the
        event of a violation of this Section 9 and that, if such violation
        should occur, injunctive relief shall be essential for the protection of
        Company and its successors and assigns. Accordingly, Employee hereby
        covenants and agrees that, in the event any of the provisions of this
        Section 9 shall be violated or breached, Company shall be entitled to
        obtain injunctive relief against the party or parties violating such
        covenants, without bond but upon due notice, in addition to such further
        or other relief as may be available at equity or law. Obtainment of such
        an injunction by Company shall not be considered an election of remedies
        or a waiver of any right to assert any other remedies which Company has
        at law or in equity. No waiver of any breach or violation hereof shall
        be implied from forbearance or failure by Company to take action
        thereof.

               (d) Employee hereby agrees that upon the commencement by Employee
        of employment with any third party during the period in which the terms
        of this Section 9 are in effect, Employee shall promptly disclose to
        each such new employer the terms of this Section 9. Employee further
        agrees and authorizes the Company to notify others, including customers
        of the Company and any such future employers of Employee, of the terms
        of this Section 9 and of Employee's obligations hereunder.

               (e) The provisions of this Section 9 shall survive any
        termination of this Agreement or of Employee's employment with the
        Company.

        10. Termination of Employment. In the event that Employee is terminated
as an employee of the Company for any reason other than as a result of
Employee's disability (which shall be subject to Section 11 below), then the
Option granted hereunder shall terminate and shall no longer be exercisable,
unless the Committee in its sole and absolute discretion, and without any
obligation to do so, determines to extend the date to exercise any Option or
portion thereof to a date that is within three (3) months after the date of
termination, but only to the extent that Employee was entitled to exercise the
Option at the date of termination, and provided that in no event shall the
Option, or any part thereof, be exercisable after the Expiration Date.

<PAGE>   5
        11. Death or Disability of Employee. In the event of the termination of
Employee's employment with Company as a result of the death or disability (as
defined in the Plan) of Employee within a period during which the Option, or any
part thereof, could have been exercised by Employee (the "Option Period"), the
Option shall lapse unless it is exercised within the Option Period or within
twelve (12) months after the date of such termination by reason of Employee's
disability by Employee or any person authorized to act on Employee's behalf, or
within twelve (12) months after the date of Employee's death by Employee's legal
representative or representatives or by the person or persons entitled to do so
under Employee's last will and testament or if Employee fails to make a
testamentary disposition of such Option or shall die intestate, by the person or
persons entitled to receive such Option under the applicable laws of descent and
distribution. An Option may be exercised following the death or disability of
the Employee only if the Option was exercisable by the Employee immediately
prior to his or her death or disability. In no event shall the Option, or any
part thereof, be exercisable after the Expiration Date. The Board or the
Committee shall have the right to require evidence satisfactory to it of the
rights of any person or persons seeking to exercise the Option under this
Section 11 to exercise the Option, and whether or not the Employee has suffered
a disability within the meaning of this Section 11 shall be determined by the
Board or the Committee.


        12. Nontransferability. The Option granted by this option agreement
shall be exercisable only during the term of the Option provided in Section 4
hereof and, except as provided in Sections 10 and 11 above, only by Employee
during his lifetime and while an Employee of the Company. The Option granted by
this option agreement shall be subject to the restrictions on transfer as set
forth in Section 17 of the Plan and Section 14 hereof.

in the manner herein provided; (ii) applicable taxes required to be withheld
have been paid or withheld in full; (iii) approval of any governmental authority
required in connection with the Option, or the issuance of shares thereunder,
has been received by the Company; and (iv) if required by the Board or the
Committee, Employee has delivered to the Board or the Committee an Investment
Letter in form and content satisfactory to the Company as provided in Section 14
hereof.

        14. Securities Act. The Company shall have the right, but not the
obligation, to cause the shares of Stock issuable upon exercise of the Option to
be registered under the appropriate rules and regulations of the Securities and
Exchange Commission. The Company shall not be required to deliver any shares of
Stock pursuant to the exercise of all or any part of the Option if, in the
opinion of counsel for the Company, such issuance would violate the Securities
Act of 1933 or any other applicable federal or state securities laws or
regulations. The Board or the Committee may require that Employee, prior to the
issuance of any such shares pursuant to exercise of the Option, sign and deliver
to the Company a written statement ("Investment Letter") stating (i) that
Employee is purchasing the shares for investment and not with a view to the sale
or distribution thereof; (ii) that Employee will not sell any shares received
upon exercise of the Option or any other shares of the Company that Employee may
then own or thereafter acquire except either (a) through a broker on a national
securities exchange or (b) with the prior written


                                       -5-
<PAGE>   6
approval of the Company; and (iii) containing such other terms and conditions as
counsel for the Company may reasonably require to assure compliance with the
Securities Act of 1933 or other applicable federal or state securities laws and
regulations. Such Investment Letter shall be in form and content acceptable to
the Board or the Committee in its sole discretion. If shares of Stock or other
securities issuable pursuant to the exercise of the Option have not been
registered under the Securities Act of 1933 or other applicable federal or state
securities laws or regulations, such shares shall bear a legend restricting the
transferability thereof, such legend to be substantially in the following form:

               "The shares represented by this certificate have not been
               registered or qualified under federal or state securities laws.
               The shares may not be offered for sale, sold, pledged or
               otherwise disposed of unless so registered or qualified, unless
               an exemption exists or unless such disposition is not subject to
               the federal or state securities laws, and the availability of any
               exemption or the inapplicability of such securities laws must be
               established by an opinion of counsel, which opinion and counsel
               shall both be reasonably satisfactory to the Company."

        15. Federal and State Taxes. Upon exercise of the Option, or any part
thereof, the Employee may incur certain liabilities for federal, state or local
taxes and the Company may be required by law to withhold such taxes for payment
to taxing authorities. Upon determination by the Company of the amount of taxes
required to be withheld, if any, with respect to the shares to be issued
pursuant to the exercise of the Option, Employee shall pay all Federal state and
local tax withholding requirements, including by having the Company withhold
Stock having a Fair Market Value on the date that tax is to be determined equal
to the tax otherwise required to be withheld.

        16. Definitions; Copy of Plan. To the extent not specifically provided
herein, all capitalized terms used in this option agreement shall have the same
meanings given to them in the Plan. By the execution of this Agreement, Employee
acknowledges receipt of a copy of the Plan.

        17. Administration. This option agreement shall at all times be subject
to the terms and conditions of the Plan and the Plan shall in all respects be
administered by the Board or by the Committee in accordance with the terms of
and as provided in the Plan. The Board or the Committee, as appropriate, shall
have sole and complete discretion with respect to all matters reserved to it by
the Plan and decisions of the majority of the Board or the Committee with
respect thereto and to this option agreement shall be final and binding upon
Employee and the Company. In the event of any conflict between the terms and
conditions of this option agreement and the Plan, the provisions of the Plan
shall control.

        18. Obligation to Exercise. Employee shall have no obligation to
exercise any option granted by this Agreement.


                                       -6-
<PAGE>   7
        19. Notice of Sale. In the event Employee disposes of any shares of
Stock acquired upon exercise of an Option by sale or exchange either (a) within
two (2) years after the Date of Grant of the Option or (b) within one (1) year
after the acquisition of such shares of Stock, Employee shall notify the Company
of such disposition and of the amount realized upon such disposition.

        20. Governing Law. This option agreement shall be interpreted and
administered under the laws of the State of Arizona without regard to conflict
of law principles.

        21. Amendments. This option agreement may be amended only by a written
agreement executed by the Company and Employee. The Company and Employee
acknowledge that changes in federal tax laws enacted subsequent to the Date of
Grant, and applicable to stock options, may provide for tax benefits to the
Company or Employee. In any such event, the Company and Employee agree that this
option agreement may be amended as necessary to secure for the Company and
Employee any benefits that may result from such legislation. Any such amendment
shall be made only upon the mutual consent of the parties, which consent (of
either party) may be withheld for any reason.

        IN WITNESS WHEREOF, the Company has caused this option agreement to be
duly executed and Employee has hereunto set his or her hand as of the date first
written above.

shares of Stock. In the event the Option shall be exercised by a person or
persons other than Employee pursuant to Section 10 hereof, such notice shall be
signed by such other person or persons and shall be accompanied by proof
acceptable to the Company of the legal right of such person or persons to
exercise the Option. All shares delivered by the Company upon exercise of the
Option as provided herein shall be fully paid and nonassessable upon delivery.

        7. Method of Payment for Options. Payment for shares purchased upon the
exercise of the Option shall be made by the Employee in cash or such other
method permitted by the Board or the Committee in its sole discretion, including
(i) tendering shares, (ii) authorizing a third party to sell the shares (or a
sufficient portion thereof) acquired upon exercise of a stock option and
assigning the delivery to the Company of a sufficient amount of the sale
proceeds to pay for all the shares acquired through such exercise, or (iii) any
combination of the above.

        8.     Confidentiality and Nondisclosure Agreement.

               (a) Employee hereby acknowledges and agrees that in the course of
        Employee's employment with the Company, Employee has and will become
        acquainted with Company Confidential Information (as defined in
        subsection (b) of this Section 8), and that Company Confidential
        Information has been developed at great expense to the Company, is
        proprietary to the Company, and is and shall remain the exclusive
        property of the Company. Accordingly, for and in consideration for the
        Options granted hereunder, and other good and valuable consideration,
        Employee hereby agrees that (i) Employee will not, without the express
        written consent of the Company, during Employee's employment with the
        Company or at any time thereafter (or until such time as Company
        Confidential Information becomes generally known, or readily
        ascertainable by proper means, by persons unrelated to the Company),
        disclose to others, copy, make any use of, or remove from the Company's
        premises any Company Confidential Information, except as Employee's
        duties for the Company may specifically require; (ii) in the event of
        dispute or litigation, Employee shall have the burden of proof by clear
        and convincing evidence that the Company Confidential Information has
        become generally known, or readily ascertainable by proper means, by
        persons unrelated to the Company; and (iii) upon termination of
        employment, Employee shall promptly deliver to the Company the originals
        and all copies of any and all materials, documents, notes, manuals, or
        lists containing or embodying Company Confidential Information, or
        relating directly or indirectly to the Company's business, in the
        possession or control of the Employee. In the event Employee violates
        this Section 8, the Option granted to Employee hereunder shall lapse
        immediately upon and at the time of such violation, regardless of
        whether Company shall then have knowledge of such violation or whether
        Employee's employment shall have then been terminated.

               (b) For purposes of this Section 8, "Company Confidential
        Information" shall include, without limitation, the following
        information which is the confidential, proprietary information, and
        trade secrets of the Company: (i) customer lists, consultant lists, and
        customer information as compiled by the Company, including customer
        orders, product or service usage, product or service volumes, pricing,
        customer technology, sale and contract terms and conditions, contract
        expirations, and other compiled customer information; (ii) the Company's
        own internal practices and procedures; (iii) the Company's financial
        condition and financial results of operation to the extent not generally
        made available to the public; (iv) supply of materials information,
        including sources and costs; (v) information relating to designs,
        formulas, developmental or experimental work, know-how, products,
        processes, computer programs, source codes, data bases, designs,
        schematics, inventions, creations, original works of authorship, or
        other subject matter related to the Company's business, research and
        development, strategic planning, manufacturing, engineering, fabrication
        or erection operations, purchasing, finance, marketing, promotion,
        distribution, licensing, and selling activities, whether now existing,
        or acquired, developed, or made available anytime in the future to the
        Company; (vi) all


                                        3
<PAGE>   4
        information which Employee has a reasonable basis to consider
        confidential or which is treated by the Company as confidential; and
        (vii) any and all information having independent economic value to the
        Company that is not generally known to, and not readily ascertainable by
        proper means by, persons who can obtain economic value from its
        disclosure or use. Employee acknowledges that such information is
        Company Confidential Information whether disclosed to or learned by
        Employee or originated by Employee during employment by the Company. In
        case of doubt, all information about the Company shall be presumed to be
        confidential.

               (c) Employee agrees that damages cannot compensate Company in the
        event of a violation of this Section 8 and that, if such violation
        should occur, injunctive relief shall be essential for the protection of
        Company and its successors and assigns. Accordingly, Employee hereby
        covenants and agrees that, in the event any of the provisions of this
        Section 8 shall be violated or breached, Company shall be entitled to
        obtain injunctive relief against the party or parties violating such
        covenants, without bond but upon due notice, in addition to such further
        or other relief as may be available at equity or law. Obtainment of such
        an injunction by Company shall not be considered an election of remedies
        or a waiver of any right to assert any other remedies which Company has
        at law or in equity. No waiver of any breach or violation hereof shall
        be implied from forbearance or failure by Company to take action
        thereof.

               (d) Employee hereby agrees that upon the commencement by Employee
        of employment with any third party during the period in which the terms
        of this Section 8 are in effect, Employee shall promptly disclose to
        each such new employer the terms of this Section 8. Employee further
        agrees and authorizes the Company to notify others, including customers
        of the Company and any such future employers of Employee, of the terms
        of this Section 8 and of Employee's obligations hereunder.

               (e) The provisions of this Section 8 shall survive any
        termination of this option agreement or of Employee's employment with
        the Company.

        9. Termination of Employment. In the event that Employee is terminated
as an employee of or consultant to the Company for any reason other than as a
result of Employee's disability (which shall be subject to Section 10 below),
then the Option granted hereunder shall terminate and shall no longer be
exercisable, unless the Committee in its sole and absolute discretion, and
without any obligation to do so, determines to extend the date to exercise any
Option or portion thereof to a date that is within three (3) months after the
date of termination, but only to the extent that Employee was entitled to
exercise the Option at the date of termination, and provided that in no event
shall the Option, or any part thereof, be exercisable after the Expiration Date.


                                        4
<PAGE>   5
        10. Death or Disability of Employee. In the event of the termination of
Employee's employment with Company as a result of the death or disability (as
defined in the Plan) of Employee within a period during which the Option, or any
part thereof, could have been exercised by Employee (the "Option Period"), the
Option shall lapse unless it is exercised within the Option Period or within
twelve (12) months after the date of such termination by reason of Employee's
disability by Employee or any person authorized to act on Employee's behalf, or
within twelve (12) months after the date of Employee's death by Employee's legal
representative or representatives or by the person or persons entitled to do so
under Employee's last will and testament or if Employee fails to make a
testamentary disposition of such Option or shall die intestate, by the person or
persons entitled to receive such Option under the applicable laws of descent and
distribution. An Option may be exercised following the death or disability of
the Employee only if the Option was exercisable by the Employee immediately
prior to his or her death or disability. In no event shall the Option, or any
part thereof, be exercisable after the Expiration Date. The Board or the
Committee shall have the right to require evidence satisfactory to it of the
rights of any person or persons seeking to exercise the Option under this
Section 10 to exercise the Option, and whether or not the Employee has suffered
a disability within the meaning of this Section 10 shall be determined by the
Board or the Committee.

        11. Nontransferability. The Option granted by this option agreement
shall be exercisable only during the term of the Option provided in Section 4
hereof and, except as provided in Sections 9 and 10 above, only by Employee
during his lifetime and while an employee of or consultant to the Company. The
Option granted by this option agreement shall be subject to the restrictions on
transfer as set forth in Section 17 of the Plan and Section 13 hereof.

        12. Delivery of Shares. No shares of Stock shall be delivered upon
exercise of the Option until (i) the purchase price shall have been paid in full
in the manner herein provided; (ii) applicable taxes required to be withheld
have been paid or withheld in full; (iii) approval of any governmental authority
required in connection with the Option, or the issuance of shares thereunder,
has been received by the Company; and (iv) if required by the Committee,
Employee has delivered to the Committee an Investment Letter in form and content
satisfactory to the Company as provided in Section 13 hereof.

        13. Securities Act. The Company shall have the right, but not the
obligation, to cause the shares of Stock issuable upon exercise of the Option to
be registered under the appropriate rules and regulations of the Securities and
Exchange Commission. The Company shall not be required to deliver any shares of
Stock pursuant to the exercise of all or any part of the Option if, in the
opinion of counsel for the Company, such issuance would violate the Securities
Act of 1933 or any other applicable federal or state securities laws or
regulations. The Company may require that Employee, prior to the issuance of any
such shares pursuant to exercise of the Option, sign and deliver to the Company
a written statement ("Investment Letter") stating (i) that Employee is
purchasing the shares for investment and not with a view to the sale or
distribution thereof; (ii) that Employee will not sell any shares received upon
exercise of the Option or any other shares of the Company that Employee may then
own or thereafter acquire except either (a)


                                        5
<PAGE>   6
through a broker on a national securities exchange or (b) with the prior written
approval of the Company; and (iii) containing such other terms and conditions as
counsel for the Company may reasonably require to assure compliance with the
Securities Act of 1933 or other applicable federal or state securities laws and
regulations. Such Investment Letter shall be in form and content acceptable to
the Company in its sole discretion. If shares of Stock or other securities
issuable pursuant to the exercise of the Option have not been registered under
the Securities Act of 1933 or other applicable federal or state securities laws
or regulations, such shares shall bear a legend restricting the transferability
thereof, such legend to be substantially in the following form:

               "The shares represented by this certificate have not been
               registered or qualified under federal or state securities laws.
               The shares may not be offered for sale, sold, pledged or
               otherwise disposed of unless so registered or qualified, unless
               an exemption exists or unless such disposition is not subject to
               the federal or state securities laws, and the availability of any
               exemption or the inapplicability of such securities laws must be
               established by an opinion of counsel, which opinion and counsel
               shall both be reasonably satisfactory to the Company."

        14. Federal and State Taxes. Upon exercise of the Option, or any part
thereof, the Employee may incur certain liabilities for federal, state or local
taxes and the Company may be required by law to withhold such taxes for payment
to taxing authorities. Upon determination by the Company of the amount of taxes
required to be withheld, if any, with respect to the shares to be issued
pursuant to the exercise of the Option, Employee shall pay all Federal, state
and local tax withholding requirements, including by having the Company withhold
Stock having a Fair Market Value on the date that tax is to be determined equal
to the tax otherwise required to be withheld.

        15. Definitions; Copy of Plan. To the extent not specifically provided
herein, all capitalized terms used in this option agreement shall have the same
meanings given to them in the Plan. By the execution of this Agreement, Employee
acknowledges receipt of a copy of the Plan.

        16. Administration. This option agreement shall at all times be subject
to the terms and conditions of the Plan and the Plan shall in all respects be
administered by the Board or by the Committee in accordance with the terms of
and as provided in the Plan. The Board or the Committee, as appropriate, shall
have sole and complete discretion with respect to all matters reserved to it by
the Plan and decisions of the majority of the Board or the Committee with
respect thereto and to this option agreement shall be final and binding upon
Employee and the Company. In the event of any conflict between the terms and
conditions of this option agreement and the Plan, the provisions of the Plan
shall control.

        17. Obligation to Exercise. Employee shall have no obligation to
exercise any option granted by this Agreement.


                                        6

        18. Governing Law. This option agreement shall be interpreted and
administered under the laws of the State of Arizona without regard to conflict
of law principles.

        19. Amendments. This option agreement shall be subject to the terms and
conditions set forth in the Plan and may be amended only by a written agreement
executed by the Company and Employee. The Company and Employee acknowledge that
changes in federal tax laws enacted subsequent to the Date of Grant, and
applicable to stock options, may provide for tax benefits to the Company or
Employee. In any such event, the Company and Employee agree that this option
agreement may be amended as necessary to secure for the Company and Employee any
benefits that may result from such legislation. Any such amendment shall be made
only upon the mutual consent of the parties, which consent (of either party) may
be withheld for any reason.

        IN WITNESS WHEREOF, the Company has caused this option agreement to be
duly executed and Employee has hereunto set his hand as of the date first
written above.

(1) Common stock equivalents, which were dilutive, were included in the
    computation of weighted average number of shares outstanding from the date 
    of grant.
(2) These items are treated as common stock equivalents from inception since
    they were issued at prices below the expected initial public offering price 
    of the Company's common shares during the twelve month period immediately 
    preceding the offering, and are computed using the treasury stock method 
    assuming an estimated initial public offering price of $11.00 per share.
