                                  THE COMPANY
 
   
     IES was founded in June 1997 to create a leading national provider of
electrical contracting and maintenance services to the commercial, industrial
and residential markets. Concurrently with the closing of the Offerings, IES
will acquire 15 electrical contracting and maintenance service companies and a
related supply company with pro forma combined year ended September 30, 1997
revenues of $312.7 million, making it one of the largest providers of electrical
contracting and maintenance services in the United States. Of such 1997 pro
forma revenues, approximately 63% was derived from commercial and industrial
contracting, approximately 25% was derived from residential contracting and
approximately 12% was derived from electrical maintenance work. Combined
revenues of the Founding Companies, which have been in business an average of 18
years, increased at an average compound annual growth rate of approximately 20%
from fiscal 1994 through 1996.
    
 
     The Company offers a broad range of electrical contracting services,
including design and installation for both new and renovation projects in the
commercial, industrial and residential markets. The Company also offers
long-term and per call maintenance services, which generally provide recurring
revenues that are relatively independent of levels of construction activity.
Typically, the Founding Companies specialize in either commercial and industrial
or residential work, although a few of the Founding Companies have both
commercial and industrial and residential operations.
 
     In certain markets the Company offers design-and-build expertise and
specialized services, which typically require specific skills and equipment and
provide higher margins than general electrical contracting and maintenance
services. In a design-and-build project, the electrical contractor applies
in-house electrical engineering expertise to design the most cost-effective
electrical system for a given structure and purpose, taking into account local
code requirements. Specialized services offered by the Company include
installations of wiring or cabling for the following: data cabling for computer
networks; fiber optic cable systems; telecommunications systems; energy
management systems which control the amount of power used in facilities; fire
alarm and security systems; cellular phone transmission sites; "smart houses"
that integrate computer, energy management, security, safety, comfort and
telecommunication systems; lightning protection systems; clean rooms for
fabrication of microprocessors and similar devices; computer rooms; back-up
electrical systems and uninterruptible power supplies; high voltage distribution
and traffic signal systems.

INDUSTRY OVERVIEW
 
     General. Virtually all construction and renovation in the United States
generates demand for electrical contracting services. Depending upon the exact
scope of work, electrical work generally accounts for approximately 8% to 12% of
the total construction cost of the Company's commercial and industrial projects
and 5% to 10% of the total construction cost of the Company's residential
projects. In recent years, the Founding Companies have experienced a growing
demand for electrical contracting services per project due to increased
electrical code requirements, demand for additional electrical capacity,
including increased capacity for computer systems, additional data cabling
requirements and the construction of smart houses with integrated systems.
 
     The overall electrical contracting industry, including commercial,
industrial and residential markets, was estimated by the U.S. Census to have
generated annual revenues in excess of $40 billion in 1992, the most recent
available U.S. Census data. These Census data indicate that, the electrical
contracting industry is highly fragmented with more than 54,000 companies, most
of which are small, owner-operated businesses, performing various types of
electrical work. The Company believes there are significant opportunities for a
well-capitalized national company to provide comprehensive electrical
contracting and maintenance services and that the fragmented nature of the
electrical contracting industry will provide significant opportunities to
consolidate commercial and industrial and residential electrical contracting and
maintenance businesses.
 
     Commercial and Industrial Market. Commercial and industrial consumers of
electrical contracting and maintenance services include general contractors;
developers; consulting engineers; architects; owners and managers of large
retail establishments, office buildings, high-rise apartments and condominiums;
theaters and restaurants; hotels and casinos; manufacturing and processing
facilities; arenas and convention centers; hospitals; school districts; military
and other government agencies; airports; prisons and car lots. The Company
provides contracting and maintenance services to the full range of commercial
and industrial customers.
 
   
     From fiscal 1994 through 1996, the Founding Companies' revenues from
electrical contracting for commercial and industrial customers have grown at an
average compound annual rate of approximately 22% per year. The Company believes
that growth in the commercial and industrial market reflects a number of
factors, including (i) levels of construction and renovation activity; (ii)
regulations imposed by electric codes, which establish minimum power and wiring
requirements; (iii) safety codes mandating additional installation of smoke
detectors and the use of ground fault circuit protection devices in more
locations; (iv) revised national energy standards that dictate the use of more
energy-efficient lighting fixtures and other equipment; (v) continuing demand to
build out lease spaces in office buildings and to reconfigure space for new
tenants; (vi) increases in use of electrical power, creating needs for increased
capacity and outlets, as well as data cabling and fiber optics and (vii)
requirements of building owners and developers to facilitate marketing their
properties to tenants and buyers by installing electrical capacity in excess of
minimum code requirements.
    
 
   
     Residential Market. Contracting work for the residential market consists
primarily of electrical installations in new single family and low-rise
multifamily residence construction for customers such as large homebuilders and
apartment developers. The Company also provides maintenance services to these
customers as well as to individual property owners in some locations. The
residential market is primarily dependent on the number of single family and
multifamily home starts, which are in turn affected by interest rates, tax
considerations and general economic conditions. Competitive factors particularly
important in the residential market include a contractor's ability to build
relationships with customers by providing services in diverse geographic markets
as construction activity shifts to new locations. The Founding Companies'
residential electrical contracting revenues have grown at an average compound
annual rate of approximately 19% from fiscal 1994 through 1996.
    
 
STRATEGY
 
     The Company believes that its size, geographical diversity of operations,
industry relationships, expertise in specialized markets, number of licensed
electricians and access to design technology give the Company significant
competitive advantages in the electrical contracting and maintenance services
industry. Through increased size, the Company believes it will have greater
ability to compete for larger jobs that require greater
                                        2
<PAGE>   8
 
   
technical expertise, personnel availability and bonding capacity, to more
effectively allocate and share resources in serving customers in each of its
markets, and to attract, train and retain qualified electricians. The Company
also believes that increased size will provide increased efficiency in materials
purchasing, computer system development, employee benefits, bonding, insurance
and financing. The Company believes that the diversity of its operations will
diminish the effects of regional and market downturns, offer opportunities to
pursue growth in its existing markets and create a base of expertise to expand
into new markets and serve new customers.
    
 
     The Company plans to leverage its experienced management and extensive
relationships within the electrical contracting industry to increase its
revenues and reduce its cost infrastructure through internal growth as well as
the acquisition of additional electrical contracting businesses. The Company's
management includes a Chief Executive Officer and two Chief Operating Officers,
each with 25 years or more of experience in the electrical contracting industry.
The Company has extensive business relationships within the industry, in part
through Founding Companies that are members of the Independent Electrical
Contractors Association ("IEC"). The IEC is the second largest electrical trade
organization in the U.S. and has nearly 3,000 contracting firms as members. The
Company's Chief Executive Officer is a past president of the IEC, and two
founders are members of the executive committee of the IEC. The IEC sponsors
forum groups, which are discussion groups of members of the IEC that foster the
sharing of best business practices. The Founding Companies are members of the
IEC and other trade organizations, and the Company intends to expand the
practice of sharing best practices among the Founding Companies and with future
acquisitions.
 
     The Company's goal is to become a leading national provider of electrical
services by improving its operations, expanding its business and markets through
internal growth and pursuing an aggressive acquisition strategy.
 
     Operating Strategy. The Company believes there are significant
opportunities to increase revenues and profitability of the Founding Companies
and subsequently acquired businesses. The key elements of the Company's
operating strategy are:
 
          Share Information, Technical Capabilities and Best Practices. The
     Company believes it will be able to expand the services it offers in its
     local markets by leveraging the specialized technical and marketing
     strengths of individual Founding Companies. The Company will identify and
     share best practices that can be successfully implemented throughout its
     operations. The Company intends to use the computer-aided-design technology
     and expertise of certain of the Founding Companies to bid for more
     design-and-build projects and to assist customers in value engineering and
     creating project documents. The Company believes that its increased size,
     capital and workforce will permit it to pursue projects that require
     greater design and performance capabilities and the ability to meet
     accelerated timetables.
 
   
          Expand Scope of Maintenance and Specialized Services. The Company
     intends to further develop its long-term and per-call maintenance service
     operations, which generally realize higher gross margins and provide
     recurring revenues that are relatively independent of levels of
     construction activity. The Company also believes that certain specialized
     businesses currently offered by only a few of the Founding Companies can be
     expanded throughout the Company and in some cases can provide higher
     margins. Through sharing of expertise and specialized licenses and the
     ability to demonstrate a safety record in specialized markets served by the
     Founding Companies, the Company intends to expand its presence and
     profitability in markets where it previously relied on subcontractors.
    
 
          Establish National Market Coverage. The Company believes that the
     growth of many of the Founding Companies has been restricted due to the
     geographic limitations of existing operations and that the Company's broad
     geographic coverage will increase internal growth opportunities. The
     Company intends to leverage its geographic diversity to bid for additional
     business from existing customers that operate on a regional and national
     basis, such as developers, contractors, homebuilders and owners of national
     chains. The Company believes that significant demand exists from such
     companies to utilize the services of a single electrical contracting and
     maintenance service provider and that existing local and regional
     relationships can be expanded as the Company develops a nationwide network.
                                        3
<PAGE>   9
 
          Operate on Decentralized Basis. The Company believes that, while
     maintaining strong operating and financial controls, a decentralized
     operating structure will retain the entrepreneurial spirit present in each
     of the Founding Companies. The Company also will be structured to allow it
     to capitalize on the considerable local and regional market knowledge and
     customer relationships possessed by each Founding Company, as well as
     companies that may be acquired in the future. By maintaining a local and
     regional focus in each of its markets, the Company believes it will be able
     to build relationships with general contractors and other customers,
     address design preferences and code requirements, respond quickly to
     customer demands for higher-margin renovation and upgrade projects and
     adjust to local conditions.
 
   
          Attract and Retain Quality Employees. The Company believes that the
     ability to attract and retain qualified electricians is a critical
     competitive factor and that the Acquisitions and the Offerings will provide
     competitive advantages in this regard. The Company intends to attract and
     develop skilled employees by extending active recruiting and training
     programs, offering stock-based compensation for key employees, and offering
     expanded career paths and more stable income through the larger public
     company. The Company believes that this ability will allow it to increase
     efficiency and pursue additional customer relationships.
    
 
   
          Achieve Operating Efficiencies. Certain administrative functions will
     be centralized following the Offerings. In addition, by combining
     overlapping operations of certain of the Founding Companies, the Company
     expects to realize savings in overhead and other expenses. The Company
     intends to use its increased purchasing power to gain volume discounts in
     areas such as electrical materials, vehicles, advertising, bonding,
     employee benefits and insurance. The Company will seek to realize cost
     savings and other benefits by the sharing of purchasing, pricing, bidding
     and other business practices and the sharing of licenses. The Company
     intends to further develop and extend the use of computer systems to
     facilitate communication among the Founding Companies. At some locations,
     the larger combined workforce will provide additional staffing flexibility.
    
 
   
     Acquisition Strategy. The Company believes that, due to the highly
fragmented nature of the electrical contracting and maintenance services
industry, it has significant opportunities to pursue its acquisition strategy.
The Company intends to focus on acquiring companies with management philosophies
based on an entrepreneurial attitude as well as a willingness to learn and share
improved business practices through open communications. The Company believes
that many electrical contracting and service businesses that lack the capital
necessary to expand operations will become acquisition candidates. For these
acquisition candidates, the Company will provide (i) information on best
practices, (ii) expertise to expand in specialized markets, (iii) the
opportunity to focus on customers rather than administration, (iv) national name
recognition, (v) increased liquidity and (vi) the opportunity for a continued
role in management. The Founding Companies participate in professional
associations such as the IEC and Associated Builders and Contractors, and the
Company intends to continue these relationships, in part to assist in
identifying attractive acquisition candidates. Other key elements of the
Company's acquisition strategy are:
    
 
          Enter New Geographic Markets. The Company will pursue acquisitions
     that are located in new geographic markets, are financially stable and have
     the customer base necessary to integrate with or complement its existing
     business. The Company also expects that increasing its geographic diversity
     will allow it to better serve an increasingly nationwide base of customers
     and further reduce the impact on the Company of local and regional economic
     cycles, as well as weather-related or seasonal variations in business.
 
   
          Expand Within Existing Markets. Once the Company has entered a market,
     it will seek to acquire other well-established electrical contracting and
     maintenance businesses operating within that region, including "tuck-in"
     acquisitions of smaller companies. The Company believes that tuck-in
     acquisitions afford the opportunity to improve its overall cost structure
     through the integration of such acquisitions into existing operations as
     well as to increase revenues through access to additional specialized
     markets, such as heavy industrial markets. Despite the integration
     opportunities afforded by such tuck-in
    
                                        4

     acquisitions, the Company intends to maintain existing business names and
     identities to retain goodwill for marketing purposes.

                   SUMMARY PRO FORMA COMBINED FINANCIAL DATA
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
   
     IES will acquire the Founding Companies simultaneously with and as a
condition to the consummation of the Offerings. For financial statement
presentation purposes, Houston-Stafford has been identified as the "accounting
acquirer." The following summary unaudited pro forma combined financial data
present certain data for the Company, as adjusted for (i) the effects of the
Acquisitions, (ii) the effects of certain other pro forma adjustments to the
historical financial statements and (iii) the consummation of the Offerings and
the application of the net proceeds therefrom. The unaudited pro forma combined
income statement data assume that the Acquisitions, the Offerings and related
transactions were closed on October 1, 1996 and are not necessarily indicative
of the results that the Company would have obtained had these events actually
then occurred or of the Company's future results. During the periods presented
below, the Founding Companies were not under common control or management and,
therefore, the data presented may not be comparable to or indicative of
post-combination results to be achieved by the Company. The unaudited pro forma
combined income statement data are based on preliminary estimates, available
information and certain assumptions that Company management deems appropriate.
The unaudited pro forma combined financial data should be read in conjunction
with the other financial information included elsewhere in this Prospectus. See
"Selected Financial Data," the Unaudited Pro Forma Combined Financial Statements
and notes thereto, and the historical financial statements for certain of the
Founding Companies and the notes thereto, all included elsewhere in this
Prospectus.

                                  RISK FACTORS
 
     Prospective investors should carefully consider the following factors as
well as the other information contained in this Prospectus. This Prospectus
contains forward-looking statements. Actual results could differ materially from
those projected in the forward-looking statements as a result of a number of
factors, including the risk factors set forth below and elsewhere in this
Prospectus.
 
ABSENCE OF COMBINED OPERATING HISTORY
 
   
     IES was founded in June 1997 but has conducted no operations and generated
no revenue to date. IES has entered into agreements to acquire the Founding
Companies simultaneously with the closing of the Offerings. The Founding
Companies have been operating and will continue to operate as separate
independent entities, and there can be no assurance that the Company will be
able to integrate these businesses on an economic basis. In addition, there can
be no assurance that the recently assembled management group will be able to
oversee the combined entity and effectively implement the Company's operating or
growth strategies. The pro forma combined financial results of the Founding
Companies cover periods during which the Founding Companies and IES were not
under common control or management and, therefore, may not be indicative of the
Company's future financial or operating results. The success of the Company will
depend on management's ability to integrate the Founding Companies and other
future acquisitions into one organization in a profitable manner. The inability
of the Company to successfully integrate the Founding Companies and to
coordinate and integrate certain administrative, banking, insurance and
accounting functions and computer systems would have a material adverse effect
on the Company's financial condition and results of operations and would make it
unlikely that the Company's acquisition program will be successful.
    
 
EXPOSURE TO DOWNTURNS IN COMMERCIAL CONSTRUCTION OR HOUSING STARTS
 
     A substantial portion of the Company's business involves installation of
electrical systems in newly constructed and renovated commercial buildings,
plants and residences. The extent to which the Company is able to maintain or
increase revenues from new installation services will depend on the levels of
new construction starts from time to time in the geographic markets in which it
operates and likely will reflect the cyclical nature of the construction
industry. The level of new commercial installation services is affected by
fluctuations in the level of new construction of commercial buildings in the
markets in which the Company operates, due to local economic conditions, changes
in interest rates and other related factors. The housing industry is similarly
affected by changes in general and local economic conditions, such as employment
and income levels, the availability and cost of financing for home buyers
(including the continued deductibility of mortgage-linked interest expenses in
determining federal income tax), consumer confidence and housing demand.
Downturns in levels of commercial construction or housing starts would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Seasonality and Quarterly Fluctuations."
 
RELIANCE ON ACQUISITIONS
 
     One of the Company's principal growth strategies is to increase its
revenues, geographic diversity and the scope of services offered and to
diversify its business mix through the acquisition of electrical contracting
companies. There can be no assurance that the Company will be able to acquire
additional businesses or to integrate and manage such additional businesses
successfully. Acquisitions may involve a number of risks, including: adverse
short-term effects on the Company's reported operating results; diversion of
management's attention; dependence on retention, hiring and training of key
personnel; risks associated with unanticipated problems or legal liabilities and
amortization of acquired intangible assets. Some or all of these risks could
have a material adverse effect on the Company's financial condition or results
of operations. In addition, to the extent that consolidation becomes more
prevalent in the industry, the prices for attractive acquisition candidates may
increase and the number of attractive acquisition candidates may decrease. The
Company believes that the electrical contracting industry may experience
consolidation on both a national and a regional level by other companies that
have acquisition objectives similar to the Company's objectives. Other
 
                                        9
<PAGE>   15
 
consolidators may have greater financial resources than the Company to finance
acquisition and internal growth opportunities and might be willing to pay higher
prices than the Company for the same acquisition opportunities. If such
acquisitions can be made, there can be no assurance that the businesses acquired
will achieve sales and profitability that justify the investment therein. See
"Business -- Strategy."
 
MANAGEMENT OF GROWTH
 
     The Company expects to grow internally and through acquisitions. Management
expects to expend significant time and effort in evaluating, completing and
integrating acquisitions and opening new facilities. There can be no assurance
that the Company's systems, procedures and controls will be adequate to support
the Company's operations as they expand. Any future growth also will impose
significant added responsibilities on members of senior management, including
the need to identify, recruit and integrate new senior level managers and
executives. There can be no assurance that such additional management will be
identified and retained by the Company. If the Company is unable to manage its
growth efficiently and effectively, or is unable to attract and retain
additional qualified management, there could be a material adverse effect on the
Company's financial condition and results of operations. See
"Business -- Strategy."
 
AVAILABILITY OF ELECTRICIANS
 
   
     The Company's ability to provide high-quality electrical services on a
timely basis is dependent upon an adequate supply of skilled electricians.
Accordingly, the Company's ability to increase its productivity and
profitability will be limited by its ability to employ, train and retain skilled
electricians necessary to meet the Company's requirements. Many companies in the
electrical contracting and service industry are currently experiencing shortages
of qualified electricians, and there can be no assurance that the Company will
be able to maintain an adequate skilled labor force necessary to operate
efficiently, that the Company's labor expenses will not increase as a result of
a shortage in the supply of skilled technicians or that the Company will not
have to curtail its planned internal growth as a result of labor shortages. See
"Business -- Company Operations -- Employee Screening, Training and
Development."
    
 
COMPETITION
 
   
     The electrical contracting industry is highly competitive and is served by
small, owner-operated private companies, public companies and several large
regional companies. Additionally, the Company could face competition in the
future from other competitors entering the market, including public utilities.
Certain of the Company's larger competitors offer a greater range of services,
such as mechanical construction, plumbing and heating, ventilation and air
conditioning services. In certain geographic regions, the Company may not be
eligible to compete for certain contracts because its employees are not subject
to collective bargaining arrangements. See "Business -- Industry Overview."
Competition in the electrical contracting industry depends on a number of
factors, including price. Certain of the Company's competitors may have lower
overhead cost structures and may, therefore, be able to provide their services
at lower rates than the Company. See "Business -- Competition."
    
 
ACQUISITION FINANCING
 
   
     The Company intends to use its Common Stock for a portion of the
consideration for future acquisitions. If the Common Stock does not maintain a
sufficient valuation or potential acquisition candidates are unwilling to accept
Common Stock as part of the consideration for the sale of their businesses, the
Company may be required to utilize more of its cash resources, if available, in
order to pursue its acquisition program. If the Company does not have sufficient
cash resources, its growth could be limited unless it is able to obtain
additional capital through future debt or equity financings.
    
 
   
     The Company has reached an agreement in principle to obtain a bank line of
credit for $65 million for working capital and acquisitions. The line of credit
will be subject to customary drawing conditions and the completion of
negotiations with the lenders and the execution of appropriate loan
documentation. See
    
 
                                       10
<PAGE>   16
 
   
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Combined Liquidity and Capital Resources."
    
 
SEASONALITY; FLUCTUATION OF QUARTERLY OPERATING RESULTS
 
     The electrical contracting service business can be subject to seasonal
variations in operations and demand that affect the construction business,
particularly in residential construction, which is affected by weather
conditions. Quarterly results may also be materially affected by the timing of
acquisitions, the timing and magnitude of acquisition assimilation costs and
regional economic conditions. Accordingly, the Company's performance in any
particular quarter may not be indicative of the results which can be expected
for any other quarter or for the entire year. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Seasonality and
Quarterly Fluctuations."
 
CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS
 
   
     Following the completion of the Acquisitions and the Offerings, the
Company's executive officers, directors and affiliates will beneficially own
approximately 41% of the total outstanding shares of Common Stock and Restricted
Common Stock. These persons, if acting in concert, will be able to continue to
exercise control over the Company's affairs, to elect the entire Board of
Directors and to control the disposition of any matter submitted to a vote of
stockholders. See "Principal Stockholders."
    
 
   
PROCEEDS OF OFFERINGS AND BENEFITS TO AFFILIATES
    
 
   
Approximately $57.5 million, or approximately 67%, of the net proceeds of the
Offerings (net of estimated offering costs, including underwriting discounts
and commissions and costs to be incurred by the Company which have been funded
by advances from Mr. Snyder) will be paid in cash to the owners of the Founding
Companies (who will generally become officers, directors or employees of the
Company). In addition, approximately $6.4 million, or approximately 7% of the
net proceeds of the Offerings, will be used to repay historical indebtedness of
the Founding Companies. Net proceeds available for acquisitions, working
capital and general corporate purposes will be approximately $22.4 million, or
26% of the net proceeds of the Offerings. In connection with the Acquisitions,
the Company expects to incur approximately $18.2 million in indebtedness to
fund the transfer of a portion of the Owner Amounts. Advances to the Company
from Mr. Snyder amounted to approximately $1.6 million as of September 30,
1997. See "Use of Proceeds" and "Certain Transactions.
    
 
BENEFITS TO FOUNDER AND MANAGEMENT
 
   
     In connection with the formation of the Company, C. Byron Snyder, the
founder of IES, and management received in the aggregate 4,052,311 shares of
Common Stock for nominal consideration. These shares will represent, in the
aggregate, approximately 17.3% of the total outstanding Common Stock following
the consummation of the Offerings. Of these shares of Common Stock, the
2,655,709 shares held by Mr. Snyder are Restricted Common Stock, which are
entitled to elect one member of the Company's Board of Directors and to one-half
of one vote for each share held on all other matters on which they are entitled
to vote. Holders of Restricted Common Stock are not entitled to vote on the
election of any other directors and will control in the aggregate 5.7% of the
votes of all shares of Common Stock. See "Principal Stockholders." Mr. Snyder
will also be reimbursed for advances made to the Company to fund expenses of the
Offerings estimated to total approximately $4.8 million. See "Use of Proceeds."
    
 
NO PRIOR MARKET, POSSIBLE VOLATILITY OF STOCK
 
   
     Prior to the Offerings, no public market for the Common Stock has existed,
and the initial public offering price, which will be determined by negotiations
between the Company and representatives of the Underwriters, may not be
indicative of the price at which the Common Stock will trade after the
Offerings. See "Underwriting" for the factors to be considered in determining
the initial public offering price. The Company intends to make application to
list the Common Stock on the NYSE, but no assurance can be given that an
    
 
                                       11
<PAGE>   17
 
   
active trading market for the Common Stock will develop or, if developed,
continue after the Offerings. The market price of the Common Stock after the
Offerings may be subject to significant fluctuations from time to time in
response to numerous factors, including variations in the reported financial
results of the Company and changing conditions in the economy in general or in
the electrical contracting and maintenance service industry in particular. In
addition, the stock markets experience significant price and volume volatility
from time to time which may affect the market price of the Common Stock for
reasons unrelated to the Company's performance.
    
 
DEPENDENCE ON KEY PERSONNEL
 
   
     The Company's operations are dependent on the continued efforts of its
executive officers and senior management of the Founding Companies. Furthermore,
the Company will be dependent on the senior management of companies that may be
acquired in the future. Although the Company will enter into an employment
agreement with each of the Company's executive officers, there can be no
assurance that any individual will continue in such capacity for any particular
period of time. The loss of key personnel, or the inability to hire and retain
qualified employees could have an adverse effect on the Company's business,
financial condition and results of operations. The Company does not maintain key
man life insurance. See "Management."
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     As of October 20, 1997, 4,052,311 shares of Common Stock were issued and
outstanding. Simultaneously with the closing of the Offerings, the stockholders
of the Founding Companies will receive, in the aggregate, 12,313,025 shares of
Common Stock as a portion of the Acquisitions Consideration. None of these
16,365,336 shares was or will be issued in a transaction registered under the
Securities Act, and, accordingly, such shares may not be sold except in
transactions registered under the Securities Act or pursuant to an exemption
from registration, including the exemptions contained in Rules 144 and 701 under
the Securities Act. In addition, the current stockholders of the Company and the
owners of the Founding Companies have agreed with the Company not to sell,
contract to sell or otherwise dispose of any shares of Common Stock owned as of
the consummation of the Acquisitions, including shares received as consideration
in the Acquisitions, for a period of two years following receipt thereof without
the Company's consent. When these shares become saleable, the market price of
the Common Stock could be adversely affected by the sale of substantial amounts
of the shares in the public market. The current stockholders of the Company and
the stockholders of the Founding Companies have certain piggy-back registration
rights with respect to their shares of Common Stock, which may be exercised
during the two-year period referred to above.
    
 
   
     As of the closing of the Offerings, the Company also will have outstanding
options to purchase up to a total of approximately 2,628,600 shares of Common
Stock issued pursuant to the Company's 1997 Stock Option Plan (the "1997 Stock
Plan"). A total of 3,500,000 shares will be issuable pursuant to the 1997 Stock
Plan. The Company intends to file a registration statement covering all such
shares under the Securities Act. See "Management -- 1997 Stock Plan."
    
 
   
     The Company currently intends to file a registration statement covering up
to an additional 6,000,000 shares of Common Stock under the Securities Act for
its use in connection with future acquisitions. These shares generally will be
freely tradeable after their issuance by persons not affiliated with the Company
unless the Company contractually restricts their resale.
    
 
     There can be no assurance that the resale or the availability for sale of
the shares of Common Stock eligible for future sale will not have an adverse
effect on the prevailing market price of the Common Stock.
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
     The Company's Amended and Restated Certificate of Incorporation, Bylaws,
employment agreements and employee benefit plans contain provisions which may
have the effect of delaying, deferring or preventing a change in control of the
Company. For example, the Company's Amended and Restated Certificate of
Incorporation and Bylaws provide for, among other things, a classified Board of
Directors, the prohibition of
 
                                       12
<PAGE>   18
 
   
stockholder action by written consent and the affirmative vote of at least
66 2/3% of all outstanding shares of Common Stock to approve the removal of
directors from office. The Company's Board of Directors has the authority to
issue shares of preferred stock in one or more series and to fix the rights and
preferences of the shares of any such series without stockholder approval. Any
series of preferred stock is likely to be senior to the Common Stock with
respect to dividends, liquidation rights and, possibly, voting. In addition, the
Board of Directors may issue certain rights pursuant to the rights plan
authorized by the Amended and Restated Certificate of Incorporation. The ability
to issue preferred stock or rights could have the effect of discouraging
unsolicited acquisition proposals. The Company's 1997 Stock Plan contains
provisions that allow for, among other things, the acceleration of vesting or
payment of awards granted under such plan in the event of a "change of control,"
as defined in such plan. In addition, the Company has entered into employment
agreements with certain executive officers and key employees allowing for cash
payments under certain circumstances following a change in control, which is
generally defined to occur upon (i) the acquisition by any person of 20% or more
of the total voting power of the outstanding securities of the Company, (ii) the
first purchase pursuant to a tender or exchange offer for Common Stock, (iii)
the approval of certain mergers, sale of substantially all the assets, or
dissolution of the Company or (iv) a change in a majority of the members of the
Company's Board of Directors.
    
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
   
     The purchasers of the shares of Common Stock offered hereby will experience
immediate dilution in the net tangible book value of their shares of $12.21 per
share (assuming an initial public offering price of $14.00 per share). See
"Dilution." In the event the Company issues additional shares of Common Stock in
the future, including shares which may be issued in connection with acquisitions
or other public or private financings, purchasers of Common Stock in the
Offerings may experience further dilution in the net tangible book value per
share of the Common Stock. See "Dilution."

                                  THE COMPANY
 
   
     IES was founded in June 1997 to create a leading national provider of
electrical contracting and maintenance services. Concurrently with and as a
condition to the closing of the Offerings, IES will acquire the 16 Founding
Companies. The Founding Companies, which have been in business for an average of
18 years, had pro forma combined year ended September 30, 1997 revenues of
approximately $312.7 million. The Acquisitions Consideration to be paid by the
Company consists of approximately $57.5 million in cash (subject to adjustment
based on the initial public offering price of the Common Stock offered hereby)
and 12,313,025 shares of Common Stock. The Acquisitions Consideration was
determined by negotiations among the Company and representatives of the Founding
Companies. See "Certain Transactions." A brief description of each of the
Founding Companies is set forth below.
    
 
   
     HOUSTON-STAFFORD. Houston-Stafford was founded in 1973 and is headquartered

significant operations in Georgia, Virginia, Tennessee and Maryland.
Houston-Stafford had revenues of approximately $81.6 million for the year ended
September 30, 1997, primarily from residential contracting and, to a lesser
extent, from commercial and industrial contracting. Because Houston-Stafford has
developed ongoing relationships with developers and homebuilders that have
regional and national operations, Houston-Stafford has experience in
establishing business operations in different locations to meet the demands of
its national clientele for electrical contracting in various regions.
Houston-Stafford has approximately 1,000 employees. In April 1997
Houston-Stafford financed the acquisition of an electrical supply company
located in Houston. Ben Mueller, executive vice president of Houston-Stafford,
will become Senior Vice President and Chief Operating Officer -- Residential and
a director of the Company following consummation of the Offering. Roy D. Brown,
president of Houston-Stafford, will sign a five-year employment agreement with
IES to continue in his position as president of Houston-Stafford following
consummation of the Offering. John Wagner, who is vice president of

Vero Beach, Florida. Daniel had combined revenues of approximately $18.4 million
for the year ended September 30, 1997, primarily from commercial and industrial
contracting (including high-rise condominiums). Because developers generally
presell a certain percentage of condominiums prior to commencing construction,
Daniel has experience in meeting the accelerated contracting schedules that are
often required to meet mandated closing periods for condominium sales. Daniel
has approximately 240 employees. Thomas Daniel, founder and president of Daniel,
will sign a five-year employment agreement with IES to continue his present
position following consummation of the Offerings.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby (assuming an initial public offering price of $14.00 per share
and after deducting estimated underwriting discounts and commissions and
estimated offering expenses payable by the Company which have been funded by
advances from Mr. Snyder) are estimated to be approximately $86.3 million 
(approximately $100.0 million if the Underwriters' over-allotment options are 
exercised in full).
    
 
   
     Of the $86.3 million net proceeds, the Company estimates that approximately
$57.5 million (subject to adjustment based on the initial public offering price
of the Common Stock) will be used to pay the cash portion of the Acquisitions
Consideration, all of which will be paid to former stockholders and other equity
owners of the Founding Companies. In addition, approximately $6.4 million of the
net proceeds will be used to repay the estimated outstanding indebtedness of the
Founding Companies at the closing of the Offerings. The estimated outstanding
indebtedness to be repaid from the proceeds of the Offerings bears interest at a
weighted average interest rate of approximately 8.8% and matures at various
dates from December 1997 through October 2012. In connection with the
Acquisitions, the Company expects to incur approximately $18.2 million in
indebtedness to fund the transfer of a portion of the Owner Amounts. The
Company will use a portion of the proceeds received from the Offerings to repay
Mr. Snyder for the $4.8 million estimated offering costs expected to be
advanced by him to the Company. Such advances amounted to approximately $1.6 
million as of September 30, 1997. See "Certain Transactions."
    
 
   
     The approximately $22.4 million of remaining net proceeds will be used for
working capital and for general corporate purposes, which are expected to
include future acquisitions. Pending such uses, the Company intends to invest
the net proceeds of the Offerings in short-term, investment-grade,
interest-bearing securities. While the Company is continuously considering
possible acquisition prospects as part of its growth strategy, the Company is
not presently engaged in active negotiations with respect to any particular
acquisition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Combined Liquidity and Capital Resources."
    
 
   
     The Company has reached an agreement in principle to obtain a bank line of
credit for $65 million for working capital and acquisitions. The line of credit
will be subject to customary drawing conditions and the completion of
negotiations with the lenders and the execution of appropriate loan
documentation. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Combined Liquidity and Capital Resources."
    
 
                                DIVIDEND POLICY
 
   
     The Company currently intends to retain its future earnings, if any, to
finance the growth, development and expansion of its business and, accordingly,
does not currently intend to declare or pay any dividends on the Common Stock
for the foreseeable future. The declaration, payment and amount of future
dividends, if any, will be at the discretion of the Company's Board of Directors
after taking into account various factors, including, among others, the
Company's financial condition, results of operations, cash flows from
operations, current and anticipated capital requirements and expansion plans,
the income tax laws then in effect and the requirements of Delaware law. In
addition, the terms of the Company's proposed credit facility will prohibit the
payment of dividends by the Company. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Combined Liquidity and
    
   
Capital Resources."

                                    DILUTION
 
   
     At September 30, 1997, after giving effect to the Acquisitions as if they
had occurred at such date, the deficit in pro forma combined net tangible book
value of the Company would have been $44.4 million, or approximately $2.71 per
share. The deficit in pro forma combined net tangible book value is equal to the
aggregate net tangible book value (tangible assets less total liabilities) of
the Company after giving effect to the Acquisitions. The number of shares used
for the per share calculation includes the 16,365,336 shares outstanding after
the Acquisitions but prior to the Offerings. After giving effect to the
Acquisitions and the sale by the Company of the 7,000,000 shares of Common Stock
offered hereby (assuming an initial public offering price of $14.00 per share
and after deducting underwriting discounts and commissions and estimated
offering expenses payable by the Company), the pro forma combined net tangible
book value of the Company would have been $41.9 million, or $1.79 per share.
This represents an immediate increase in pro forma net tangible book value of
$4.50 per share to existing stockholders and an immediate dilution in net
tangible book value of $12.21 per share to new investors purchasing the shares
of Common Stock in the Offerings. The following table illustrates this per share
dilution:

                            SELECTED FINANCIAL DATA
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
   
     IES will acquire the Founding Companies simultaneously with and as a
condition to the consummation of the Offerings. For financial statement
presentation purposes, however, Houston-Stafford has been designated as the
"accounting acquirer." The following selected historical financial data for
Houston-Stafford as of December 31, 1995 and 1996, and September 30, 1997, and
for the years ended December 31, 1994, 1995 and 1996, and the year ended
September 30, 1997, have been derived from audited financial statements of
Houston-Stafford included elsewhere in this Prospectus and reflect all
adjustments, consisting of normal recurring adjustments, necessary for a fair
presentation of such data. The selected historical financial data for the nine
months ended September 30, 1996 and 1997, and as of December 31, 1992, 1993 and
1994, and for the years ended December 31, 1992 and 1993, have been derived from
the unaudited financial statements of Houston-Stafford, which have been prepared
on the same basis as the audited financial statements and, in the opinion of
Company management, reflect all adjustments consisting of normal recurring
adjustments, necessary for a fair presentation of such data. The results of
operations for the nine months ended September 30, 1997 should not be regarded
as indicative of the results that may be expected for the full year.
    
 
   
     The summary unaudited pro forma combined financial data below present
certain data for the Company, adjusted for (i) the effects of the Acquisitions,
(ii) the effects of certain other pro forma adjustments to the historical
financial statements and (iii) the consummation of the Offerings and the
application of the net proceeds therefrom. The unaudited pro forma combined
income statement data assume that the Acquisitions, the Offerings and related
transactions were closed on October 1, 1996, and are not necessarily indicative
of the results that the Company would have obtained had these events actually
occurred at that date or indicative of the Company's future results. During the
periods presented below, the Founding Companies were not under common control or
management and, therefore, the data presented may not be comparable to or
indicative of post-combination results to be achieved by the Company. The
unaudited pro forma combined income statement data are based on preliminary
estimates, available information and certain assumptions that Company management
deems appropriate. The unaudited pro forma combined financial data should be
read in conjunction with the other financial information included elsewhere in
this Prospectus. See the Unaudited Pro Forma Combined Financial Statements and
the notes thereto, included elsewhere in this Prospectus.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
     The following discussion should be read in conjunction with the Founding
Companies' Financial Statements and related notes thereto and "Selected
Financial Data" appearing elsewhere in this Prospectus.
 
   
     The Company's revenues are derived primarily from electrical construction
and maintenance services provided to commercial, industrial and residential
customers. Approximately 63% of the Company's pro forma combined year ended
September 30, 1997 revenues were from commercial and industrial contracting,
approximately 25% were from residential contracting, and approximately 12% were
derived from electrical maintenance work. In addition, approximately 88% of the
Company's pro forma combined year ended September 30, 1997 revenues of $312.7
million were derived from new construction and renovation, and approximately 12%
were attributable to maintenance work (including repair and replacement).
Revenues from fixed price construction and renovation contracts are generally
accounted for on a percentage-of-completion basis, using the cost-to-cost
method. The cost-to-cost method measures the percentage completion of a contract
based on total costs incurred to date compared to total estimated costs at
completion. Maintenance and other service revenues are recognized as the
services are performed.
    
 
   
     Cost of services consists primarily of salaries and benefits of employees,
subcontracted services, materials, parts and supplies, depreciation, fuel and
other vehicle expenses and equipment rentals. The Company's gross margin, which
is gross profit expressed as a percentage of revenues, depends on the relative
proportions of costs related to labor and materials. On jobs in which a higher
percentage of the cost of services consists of labor costs, the Company
typically achieves higher gross margins than on jobs where materials represent
more of the cost of services. Materials costs can be calculated with relatively
more accuracy than labor costs, and the Company seeks to maintain higher margins
on its labor-intensive projects to compensate for the potential variability of
labor costs for these projects. Selling, general and administrative expenses
consist primarily of compensation and related benefits for owners,
administrative salaries and benefits, advertising, office rent and utilities,
communications and professional fees. Certain owners and certain key employees
of the Founding Companies have agreed to reductions in their compensation and
related benefits totaling approximately $6.1 million in year ended September 30,
1997 in connection with the Acquisitions. Such reductions in salaries, bonuses
and benefits have been reflected as a pro forma adjustment in the Unaudited Pro
Forma Combined Statement of Operations and are reflected in the terms of
employment agreements with the Company.
    
 
   
     The Company believes that it will realize savings from (i) consolidation of
insurance and bonding programs; (ii) reduction in other general and
administrative expenses, such as training and advertising; (iii) the Company's
ability to borrow at lower interest rates than the Founding Companies; (iv)
consolidation of operations in certain locations and (v) greater volume
discounts from suppliers of materials, parts and supplies. Offsetting these
savings will be costs related to the Company's new corporate management, costs
of being a public company and integrating the Acquisitions.
    
 
   
     The Company has sold an aggregate of 4,052,311 shares of Common Stock to
its management and has recorded (for financial statement presentation purposes)
a non-recurring, non-cash compensation charge of $38.1 million relating to such
sale. This non-recurring compensation charge has been excluded from the total
pro forma combined amounts in the Unaudited Pro Forma Combined Financial
Statements.
    
 
   
     As a result of the Acquisitions, $122.7 million, representing the excess of
the consideration paid over the fair value of the net assets to be acquired,
will be recorded as goodwill on the Company's balance sheet. Goodwill will be
amortized as a non-cash charge to the income statement over a 40-year period.
The pro forma impact of this amortization expense, which is non-deductible for
tax purposes, is $3.1 million per year.

SUPPLEMENTAL UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION OF THE FOUNDING
COMPANIES
    
 
   
     The following supplemental unaudited pro forma combined financial
information for the periods presented do not purport to present those of the
combined Founding Companies in accordance with generally accepted accounting
principles, but represent merely a summation of the revenues, cost of services
(including depreciation), gross profit, selling, general and administrative
expenses and income from operations of the individual Founding Companies on a
historical basis and excludes the effects of the pro forma adjustments that are
included in the Unaudited Pro Forma Combined Statements appearing elsewhere in
this Prospectus. Selling, general and administrative expenses for periods prior
to the Acquisitions reflect the effects of salary and bonus distributions to the
owners of the Founding Companies. The data will not be comparable to, and may
not be indicative of, the Company's post-combination results of operations
because (i) the Founding Companies were not under common control or management
and had different tax structures (generally, S corporations or partnerships)
during the periods presented, (ii) the Company will use the purchase method to
establish a new basis of accounting to record the Acquisitions, (iii) the
Company will incur incremental costs for its corporate management and the costs
of being a public company and (iv) the combined data do not reflect the
potential benefits and cost savings the Company expects to realize when
operating as a combined entity.

combined financial information for the periods indicated:

(a) The fiscal years ended 1994, 1995 and 1996 are the years ended December 31,
    1994, 1995 and 1996 for all Founding Companies, except for Pollock and
    Hatfield, for which the fiscal years presented are the years ended October
    31, 1994, 1995 and 1996; Rodgers, for which the fiscal years presented are
    the years ended September 30, 1995, 1996 and 1997; and Summit, for which the
    fiscal years presented are the years ended March 31, 1995, 1996 and 1997.
    
 
   
(b) Represents the year ended September 30, 1997 for all Founding Companies,
    except that the amounts included for Ace, Hatfield, Popp and Reynolds are
    for the year ended June 30, 1997.
    
 
   
       Pro Forma Combined Results for the year ended September 30, 1997,
       compared to the fiscal year ended 1996
    
 
   
     Revenues increased approximately $40.5 million, or 15% from $272.2 million
for the fiscal year ended 1996 to $312.7 million for the year ended September
30, 1997. The increase in combined revenues occurred primarily at
Houston-Stafford, Mills, Daniel, Pollock and Haymaker. Houston-Stafford's
revenues increased $11.0 million, or 16% from 1996 to 1997, primarily due to an
overall increase in market demand and the consolidation of an electrical supply
company partially offset by the effects of unusually rainy weather in Texas.
Mills' revenues increased $9.0 million, or 14% from 1996 to 1997, primarily due
to a full year of revenues in 1997 from the acquisition of Fort Worth Regional
Electrical Systems, L.L.C. ("Regional Electric") in June 1996. Daniel's revenues
increased $5.8 million, or 46% from 1996 to 1997 primarily due to increased
contract revenues on several large high rise condominium projects in south
Florida. Pollock's revenues increased $4.5 million, or 28%, from 1996 to 1997,
primarily due to an increase in large commercial contracts, increased data
cabling work, and higher revenues for service work. Haymaker's revenues
increased
    
 
                                       24
<PAGE>   30
 
   
$4.2 million, or 56%, from 1996 to 1997, primarily due to a large hospital
contract and an overall increase in construction activity in Birmingham,
Alabama. Of the remaining ten Founding Companies, five reported an increase in
revenues and five recorded a decline in revenues between 1996 and 1997. The most
significant decline in revenue of $0.8 million occurred at Bexar-Calhoun,
primarily due to the completion in 1996 of an unusually large electrical
construction contract for a state university in Laredo, Texas. The most
significant increase in revenues among these other Founding Companies of $2.5
million or 18% occurred at Amber, primarily due to three large retail
construction contracts in 1997.
    
 
   
Gross profit increased $9.1 million, or 16% from $55.9 million for the fiscal
year ended 1996, to $65.0 million for the year ended September 30, 1997. The
increase in combined gross profit occurred primarily due to increases in gross
profit of $3.9 million or 30% at Houston-Stafford, $2.0 million or 70% at
Daniel, $1.3 million or 59% at Pollock and $1.3 million or 79% at Amber.
Houston-Stafford's gross margin increased from 18% in 1996 to 20% in 1997,
Daniel's gross margin increased from 23% in 1996 to 27% in 1997, Pollock's
gross margin increased from 14% in 1996 to 18% in 1997 and Amber's gross margin
increased from 12% in 1996 to 18% in 1997. The increases in Houston-Stafford's
gross profit and gross margin are primarily attributable to favorable pricing
associated with increased demand and higher discounts on certain long-term
material purchase commitments. Daniel's gross profit and gross margin increases
are primarily due to increased labor efficiencies and an increase in higher
margin high-rise residential contracts. Pollock's gross margin increases are
due to certain lower than expected and loss contracts in 1996 that did not
recur in 1997. Amber's gross profit increased as a result of an increase in
overall demand as well as demand for higher margin retail construction
contracts.
    
 
   
Selling, general and administrative expenses increased $7.5 million from $34.5
million in 1996 to $42.0 million in 1997. This increase occurred primarily due
to an increase in selling, general and administrative expenses of $3.7 million
at Houston-Stafford and $1.2 million at Mills. The increase in
Houston-Stafford's selling, general and administrative expenses was primarily
attributable to increased bonuses for certain key employees and to a lesser
degree higher insurance costs. Mills' increase in selling, general and
administrative expenses was attributable to a full year of general and
administrative expenses relating to the June 1996 acquisition of Regional
Electric, and a $0.2 million severance payment to the former owner of Regional
Electric.
    
 
   
  Pro Forma Combined Results for the fiscal year ended 1996, compared to the
  fiscal year ended 1995
    
 
   
     Revenues increased approximately $60.6 million, or 29% from $211.6 million
for the fiscal year ended 1995 to $272.2 million for the fiscal year ended 1996.
The increase in combined revenues occurred primarily at Houston-Stafford, Mills
and Bexar-Calhoun. Houston-Stafford's revenues increased $16.4 million, or 30%
from 1995 to 1996, primarily due to an overall increase in market demand and new
contractual arrangements for Houston-Stafford to be the sole or primary provider
of electrical installation services for certain residential contractors. Mills'
revenues increased $30.1 million, or 86% from 1995 to 1996, primarily due to the
acquisition of Regional Electric in June 1996 (which represents approximately
$5.2 million of 1996 revenues), an increase in market demand for large
industrial construction contracts for manufacturing and distribution facilities
in the greater Dallas area, and a 30% increase in maintenance and service
revenues. Bexar-Calhoun's revenues increased $5.3 million, or 19% from 1995 to
1996, as certain personnel were reassigned to the growing markets around Laredo
and New Braunfels, Texas, resulting in a $3.6 million increase in revenues in
these two markets between 1995 and 1996. Of the remaining 12 Founding Companies,
seven reported an increase in revenues, one reported relatively constant
revenues and four recorded a decline in revenues between 1995 and 1996. The most
significant decline in revenue of $2.0 million occurred at Ace, where an
unusually high demand for design-and-build projects in Valdosta, Georgia in 1995
did not recur in 1996. The most significant increase in revenues among these
other Founding Companies of $4.2 million or 43% occurred at Amber due to an
increase in large commercial projects on shopping malls and grocery stores in
central Florida.
    
 
   
     Gross profit increased $16.6 million, or 42% from $39.2 million for the
fiscal year ended 1995, to $55.9 million for the fiscal year ended 1996. Gross
margin increased to 21% in 1996 from 19% in 1995. The
    
 
                                       25

increase in combined gross profit occurred primarily due to increases in gross
profit of $5.4 million or 74% at Houston-Stafford, $7.0 million or 89% at Mills,
and $1.3 million or 18% at Bexar-Calhoun. Houston-Stafford's gross margin
increased from 14% in 1995 to 18% in 1996, Mills' gross margin increased from
22% in 1995 to 23% in 1996, and Bexar-Calhoun's gross margin remained constant
at 24% in 1995 and 1996. The increases in Houston-Stafford's gross profit and
gross margin are primarily attributed to favorable pricing associated with
increased demand and higher discounts on certain long-term material purchase
commitments. Mills' gross profit and gross margin increases are primarily
attributed to the acquisition of Regional Electric, increased demand for complex
industrial contracts, and an increase in higher margin maintenance service
revenues. Bexar-Calhoun's gross profit increased as a result of its overall
increase in business volume.
    
 
     Selling, general and administrative expenses increased 21% from $28.5
million in 1995 to $34.5 million in 1996. This increase occurred primarily due
to increases in selling, general and administrative expenses of $1.8 million at
Houston-Stafford and $2.9 million at Mills. The increase in Houston-Stafford's
selling, general and administrative expenses was primarily attributed to the
addition of infrastructure associated with its growth. Mills' increase in
selling, general and administrative expenses was attributed to increased
business volume, including that related to the acquisition of Regional Electric,
and increases in discretionary bonus and savings plan distributions.
 
   
  Pro Forma Combined Results for the fiscal year ended 1995 compared to the
  fiscal year ended 1994
    
 
   
     Revenues increased $30.4 million, or 17% from $181.2 million for the fiscal
year ended 1994, to $211.6 million for the fiscal year ended 1995. The increase
in combined revenues occurred primarily at Houston-Stafford, Mills and
Bexar-Calhoun. Houston-Stafford's revenues increased $6.1 million, or 13% from
1994 to 1995, primarily due to an overall increase in demand and a new contract
under which Houston-Stafford is the sole or primary provider of electrical
installation services for a multifamily residential contractor. Mills' revenues
increased $9.8 million, or 38% from 1994 to 1995, primarily due to increased
demand for higher margin industrial contracting services and a 61% increase in
maintenance and service revenues. Bexar-Calhoun's revenues increased $4.5
million, or 20% from 1994 to 1995, due to an increase in retail construction
activity in San Antonio.
    
 
     Of the remaining 12 Founding Companies, seven reported an increase in
revenues, two reported relatively constant revenues and three reported a decline
in revenues between 1994 and 1995. The most significant decline in revenues of
$1.3 million occurred at Hatfield, where an unusually large $2.0 million
contract was completed in 1994 and no comparable contract was performed in 1995.
The most significant increase in revenue among these other Founding Companies of
$2.6 million occurred at Ace due to an unusually high demand for
design-and-build commercial projects in 1995 as compared to 1994.
 
   
     Gross profit increased $7.7 million, or 24% from $31.5 million for the
fiscal year ended 1994, to $39.2 million for the fiscal year ended 1995. Gross
margin increased to 19% in 1995 from 17% in 1994. The increase in combined gross
profit occurred primarily due to increases in gross profit of $1.6 million or
26% at Houston-Stafford, $3.3 million or 71% at Mills, and $1.5 million or 30%
at Bexar-Calhoun. Houston-Stafford's gross margin increased from 12% in 1994 to
14% in 1995, Mills' gross margin increased from 18% in 1994 to 22% in 1995, and
Bexar-Calhoun's gross margin increased from 22% in 1994 to 24% in 1995,
respectively. The increase in Houston-Stafford's gross profit and gross margin
are primarily attributed to favorable pricing related to increased demand.
Mills' gross profit and gross margin increases are primarily attributed to
increased market demand for complex industrial contracts, and an increase in
higher margin maintenance and service revenues. Bexar-Calhoun's gross profit and
gross margin increased as a result of higher margin retail construction
contracts in San Antonio, Texas.
    
 
   
     Selling, general and administrative expenses increased 20% from $23.8
million in 1994 to $28.5 million in 1995. The increase in combined selling,
general and administrative expenses occurred primarily due to increases in
selling, general and administrative expenses of $0.7 million at
Houston-Stafford, $1.3 million at Mills and $0.5 million at Bexar-Calhoun. The
increase in Houston-Stafford's selling general and administrative expenses was
attributed to the addition of administrative infrastructure associated with its
growth. Mills' increase in selling, general and administrative expenses was
attributed to increased business volume and
    
 
                                       26

increases in discretionary bonus and savings plan distributions. Bexar-Calhoun's
increase in selling, general and administrative expenses was attributed to the
addition of administrative infrastructure associated with Bexar-Calhoun's
growth.
    
 
COMBINED LIQUIDITY AND CAPITAL RESOURCES
 
   
     Upon consummation of the Acquisitions and after applying the estimated net
proceeds of the Offerings as discussed under "Use of Proceeds," the Company will
have $25.8 million of pro forma cash and cash equivalents, $51.3 million of pro
forma working capital and no outstanding indebtedness other than debt relating
to Owner Amounts and capital lease obligations totaling $19.3 million. The
Founding Companies' historical indebtedness of $8.1 million is anticipated to be
transferred to the founders or repaid from the proceeds of the Offerings.
    
 
   
     On a combined basis, the Founding Companies generated $12.3 million of cash
from operating activities during the year ended September 30, 1997. Net cash
used in investing activities was $5.7 million on a combined basis and was
primarily used for capital expenditures. Net cash used in financing activities
was $7.8 million on a combined basis and was primarily used for debt repayment
and capital distributions.
    
 
   
     The Company has entered into a preliminary agreement with a commercial bank
under which it expects to enter into a credit facility effective concurrently
with the closing of the Offerings. According to the proposed terms of the
agreement, the credit facility will be a three-year revolving credit facility of
up to $65 million to be used for working capital and capital expenditures, to
finance acquisitions and for general corporate purposes. The Company's existing
and future subsidiaries will guarantee the repayment of all amounts due under
the facility, and the facility will be secured by the capital and stock of the
guarantors and the accounts receivable of the Company and the guarantors. The
Company expects that the credit facility will require the consent of the lenders
for acquisitions exceeding a certain level of cash consideration, prohibit the
payment of cash dividends by the Company, restrict the ability of the Company to
incur other indebtedness and require the Company to comply with certain
financial covenants. Availability of the credit facility will be subject to
customary drawing conditions, completion of negotiations with the lenders and
execution of definitive loan documentation.
    
 
   
     The Company anticipates that its cash flow from operations and proceeds
from the Offerings will provide sufficient cash to enable the Company to meet
its working capital needs, debt service requirements and planned capital
expenditures for property and equipment through 1998.
    
 
   
     The Company intends to continue pursuing attractive acquisition
opportunities. The timing, size or success of any acquisition effort and the
associated potential capital commitments cannot be predicted. The Company
expects to fund future acquisitions primarily with a portion of the net proceeds
of the Offerings, working capital, cash flow from operations and borrowings,
including any unborrowed portion of the proposed credit facility, as well as
issuances of additional equity.
    
 
   
     Due to the relatively low levels of inflation experienced in fiscal 1994,
1995 and 1996, inflation did not have a significant effect on the results of the
combined Founding Companies in those fiscal years, or any of the Founding
Companies individually.
    
 
HOUSTON-STAFFORD RESULTS OF OPERATIONS
 
   
     Houston-Stafford was founded in 1973 and is headquartered in Stafford,
Texas near Houston. It operates primarily in Texas, with other significant

     Revenues increased $11.0 million, or 21% from $53.1 million for the nine
months ended September 30, 1996 to $64.1 million for the nine months ended
September 30, 1997, primarily as a result of increased demand and the
consolidation of an electrical supply company, partially offset by the effects
of unusually rainy weather in Texas.
    
 
   
     Gross profit increased $3.9 million during the first nine months of 1997 to
$12.5 million, and gross margin increased to 19% in 1997 from 16% in 1996 as a
result of favorable pricing related to the increase in demand and higher
discounts on certain long-term material purchase commitments.
    
 
   
     Selling, general and administrative expenses increased 83% from $4.4
million to $8.1 million. The increase was attributable to an increase in bonuses
for certain key employees and to a lesser degree higher insurance costs.

     Revenues increased $16.4 million, or 30% from $54.1 million for the year
ended December 31, 1995, to $70.5 million for the year ended December 31, 1996,
primarily due to an overall increase in demand and new contracts under which
Houston-Stafford is the sole or primary provider of electrical installation
services for certain significant residential contractors.
    
 
     Gross profit increased $5.4 million, or 74% from $7.4 million for the year

attributed to favorable pricing related to the increase in demand and higher
discounts on certain long-term material purchase commitments.
    
 
   
     Selling, general and administrative expenses increased 30% from $6.0
million to $7.8 million. The increase was attributable to the addition of
administrative infrastructure necessary to support the company's growth and the
establishment of a new merit bonus system. Selling, general, and administrative
expenses as a percentage of revenues remained constant during 1996 when compared
to 1995.

ended December 31, 1994, to $54.1 million for the year ended December 31, 1995,
due to increased demand and a new contract where the company is the sole or
primary provider of electrical contracting services for a significant
multi-family residential contractor.
    
 
     Gross profit increased $1.6 million, or 26% from $5.8 million for the year
ended December 31, 1994 to $7.4 million for the year ended December 31, 1995.
Gross margin increased from 12% to 14% over these periods due to favorable
pricing partially offset by lower profits from government projects in 1995.
 
     Selling, general and administrative expenses increased 14% in 1995 when
compared to 1994 as a result of the additional infrastructure necessary to
support the company's growth. Selling, general and administrative expenses as a

  Mills results for the nine months ended September 30, 1997 compared to nine
  months ended September 30, 1996
    
 
   
     Revenues increased $8.9 million, or 20% from $43.7 million for the nine
months ended September 30, 1996 to $52.6 million for the nine months ended
September 30, 1997, primarily as a result of the acquisition of Regional
Electric, which specializes in commercial and industrial electrical contracting
and fire alarm, data cabling and control system installation in the greater Fort
Worth area.
    
 
   
     Gross profit decreased $1.1 million, or 11%, during the first nine months
of 1997 as compared to the nine months ended September 30, 1996. Gross margin
decreased from 22% to 16% due to a decrease in demand for higher margin, complex
industrial work offset by an increase in demand for lower margin commercial
work, as well as a planned increase in the operating infrastructure at Regional
Electric to support Mill's growth strategy in the Ft. Worth market.
    
 
   
     Selling, general and administrative expenses increased 30% from $3.8
million to $5.0 million. The increase was attributable to a full year of general
and administrative expenses relating to the June 1996 acquisition of Regional
Electric, and a $0.2 million severance payment to the former owner of Regional
Electric.

ended December 31, 1996, to $74.4 million for the year ended September 30, 1997,
primarily due to the acquisition of Regional Electric in June 1996 (which
represents approximately $13 million of 1997 and $5.2 million of 1996 revenues).
    
 
   
     Gross profit decreased $1.1 million, or 7% from $14.9 million for the year
ended December 31, 1996 to $13.8 million for the year ended September 30, 1997.
Gross margin decreased from 23% to 19% due to a decrease in demand for higher
margin, complex industrial work offset by an increase in demand for lower margin
commercial work, as well as a planned increase in the operating infrastructure
at Regional Electric to support Mill's growth strategy on the Ft. Worth market.
    
 
   
     Selling, general and administrative expenses increased 15% from $7.6
million to $8.8 million. The increase was attributable to a full year of general
and administrative expenses relating to the June 1996 acquisition of Regional
Electric, and a $0.2 million severance payment to the former owner of Regional
Electric.

     Revenues increased $30.1 million, or 86% from $35.3 million for the year
ended December 31, 1995 to $65.4 million for the year ended December 31, 1996,
primarily due to the acquisition of Regional Electric in June 1996 (which
represents approximately $5.2 million of 1996 revenues), an increase in demand
for large and complex industrial construction contracts for manufacturing and
distribution facilities in the greater Dallas area for which only a select group
of electrical contractors have the resources and expertise to bid and a

ended December 31, 1995 to $14.9 million for the year ended December 31, 1996.
Gross margin increased to 23% from 22% during this period due to an increase in
higher margin maintenance and service work.
 
     Selling, general and administrative expenses increased 61% from $4.7
million to $7.6 million. The increase was attributable to increased business
volume, including that related to the acquisition of operations of Regional
Electric and increases in discretionary bonus and savings plan distributions.

  Bexar-Calhoun results for the nine months ended September 30, 1997 compared to
  nine months ended September 30, 1996
    
 
   
     Revenues decreased $0.9 million, or 3% from $25.0 million in 1996 to $24.1
million in 1997, primarily due to an increase in overall growth offset by the
completion in 1996 of an unusually large electrical construction contract for a
state university in Laredo, Texas.
    
 
   
     Gross profit decreased $0.8 million, or 13% from $6.1 million in 1996 to
$5.3 million in 1997. Gross margin decreased from 24% in 1996 to 22% in 1997.
The decrease in gross profit related to completion of the large state university
contract in 1996 and gross margin declined due to a change in customer mix
associated with a decrease in higher margin retail construction in San Antonio.
    
 
     Selling, general and administrative expenses remained relatively constant
from 1996 to 1997.

     Gross profit decreased $0.8 million, or 10% from $8.0 million for the year
ended December 31, 1996, to $7.2 million for the year ended September 30, 1997.
Gross margins decreased to 22% from 24% over these periods. The decrease in
gross profit related to completion of the large state university contract in
1996 and gross margin declined due to a change in customer mix associated with a
decrease in higher margin retail construction in San Antonio.

     Revenues increased $5.3 million, or 19% from $27.7 million in 1995 to $33.0
million in 1996, primarily due to reassignment of certain personnel to Laredo
and New Braunfels, Texas. Bexar-Calhoun realized a $3.6 million increase in
revenues in these two markets between 1995 and 1996, in part from an unusually
large electrical construction contract for a university in Laredo, Texas.
    
 
   
     Gross profit increased $1.2 million, or 18% from $6.8 million in 1995 to
$8.0 million in 1996. Gross margin remained stable over these periods. The
increase in gross profit was attributed to higher revenues.
    
 
     Selling, general and administrative expenses did not significantly change

  December 31, 1994
 
     Revenues increased $4.5 million, or 20% from $23.2 million in 1994 to $27.7
million in 1995, primarily due to a significant increase in the volume of
Bexar-Calhoun's retail construction business in the San Antonio, Texas market.

due to higher margin retail construction.
 
     Selling, general and administrative expenses increased 18% from $3.1
million in 1994 to $3.6 million in 1995. The increase was attributable to the
addition of infrastructure associated with Bexar-Calhoun's growth.

     Revenues increased $1.9 million, or 16% from $12.5 million for the nine
months ended September 30, 1996 to $14.5 million for the nine months ended
September 30, 1997, due to a significant increase in market demand that was
offset by work delays caused by the harsh winter, which lasted from November
1996 through early April 1997.
    
 
   
     Gross profit increased $0.3 million, or 10% from $2.8 million for the nine
months ended September 30, 1996 to $3.0 million for the nine months ended
September 30, 1997. Gross margin decreased to 21% from 22% over these periods.
The decreases in the gross margin are solely attributed to the harsh winter and
related work delays in early 1997.
    
 
   
     Selling, general and administrative expenses increased 5% from $2.1 million
to $2.3 million. The increase was attributable to the increase in market demand
and related infrastructure costs.

period ended December 31, 1996 to $18.8 million for the fiscal year ended
September 30, 1997, due to a significant increase in market demand that was
offset by work delays caused by the harsh winter, which lasted from November
1996 through early April 1997.
    
 
   
     Gross profit increased $0.3 million, or 7% from $4.0 million for the fiscal
period ended December 31, 1996 to $4.3 million for the fiscal year ended
September 30, 1997. The increase in gross profit is attributable to increased
market demand that was offset by work delays caused by the harsh winter, which
lasted from November 1996 through early April 1997. Gross margin decreased to
22% from 24% over these periods.

which started in November 1996 and continued through early April 1997.
 
   
     Gross profit increased $0.2 million, or 5% from $3.8 million for the year
ended December 31, 1995 to $4.0 million for the year ended December 31, 1996.
There was no significant change in gross margin. The gross profit and gross
margin increases in 1996 when compared to 1995 were attributed to increased
margins on service work in 1996 and increased revenues.
    
 
     Selling, general and administrative expenses remained constant over these
periods.
 
  Muth results for the year ended December 31, 1995 compared to the year ended
  December 31, 1994
 
   
     Revenues increased $2.5 million, or 19% from $13.5 million for the year
ended December 31, 1994 to $16.0 million for the year ended December 31, 1995,
primarily due to increased overall demand.
    
 
     Gross profit increased $0.1 million from $3.7 million for the year ended
December 31, 1994, to $3.8 million for the year ended December 31, 1995. Gross
margin decreased to 24% from 27% over these periods due to a lower and more
normal mix of higher margin design-and-build projects in 1995.
 
     Selling, general and administrative expenses increased 9% from $2.7 million
to $2.9 million. The increase was due to an increase in administrative salaries
attributable to the additional infrastructure associated with Muth's growth.

SEASONALITY AND QUARTERLY FLUCTUATIONS
 
     The Company's results of operations from residential construction are
seasonal, depending on weather trends, with typically higher revenues generated
during the spring and summer and lower revenues during the fall and winter. The
commercial and industrial aspect of the Company's business is less subject to
seasonal trends, as this work is performed inside structures protected from the
weather. The Company's service business is not affected by seasonality. In
addition, the construction industry has historically been highly cyclical. The
Company's volume of business may be adversely affected by declines in
construction projects resulting from adverse regional or national economic
conditions. Quarterly results may also be materially affected by the timing of
acquisitions and the timing and magnitude of acquisition assimilation costs.
Accordingly, operating results for any fiscal period are not necessarily
indicative of results that may be achieved for any subsequent fiscal period.

     IES was founded in June 1997 to create a leading national provider of
electrical contracting and maintenance services to the commercial, industrial
and residential markets. Concurrently with the closing of the Offerings, IES
will acquire 15 electrical contracting and maintenance service companies and a
related supply company with pro forma combined year ended September 30, 1997
revenues of $312.7 million, making it one of the largest providers of electrical
contracting and maintenance services in the United States. Of such pro forma
revenues, approximately 63% was derived from commercial and industrial
contracting, approximately 25% was derived from residential contracting and
approximately 12% was derived from electrical maintenance work. Combined
revenues of the Founding Companies, which have been in business an average of 18
years, increased at an average compound annual growth rate of approximately 20%
from fiscal 1994 through 1996.
    
 
     The Company offers a broad range of electrical contracting services,
including design and installation for both new and renovation projects in the
commercial, industrial and residential markets. The Company also offers
long-term and per-call maintenance services, which provide recurring revenues
that are relatively independent of levels of construction activity. Typically,
the Founding Companies specialize in either commercial and industrial or
residential work, although a few of the Founding Companies have both commercial
and industrial and residential operations.
 
     In certain markets the Company offers design-and-build expertise and
specialized services, which typically require specific skills and equipment and
provide higher margins than general electrical contracting and maintenance
services. In a design-and-build project, the electrical contractor applies
in-house electrical engineering expertise to design the most cost-effective
electrical system for a given structure, local code requirements and purpose.
Specialized services offered by the Company include installations of wiring or
cabling for the following: data cabling for computer networks; fiber optic cable
systems; telecommunications systems; energy management systems which control the
amount of power used in facilities; fire alarm and security systems; cellular
phone transmission sites; "smart houses" that integrate computer, energy
management, security, safety, comfort and telecommunication systems; lightning
protection systems; clean rooms for fabrication of microprocessors and similar
devices; computer rooms; back-up electrical systems and uninterruptible power
supplies; high voltage transmission distribution and traffic signal systems.
 
INDUSTRY OVERVIEW
 
     General. Virtually all construction and renovation in the United States
generates demand for electrical contracting services. Depending upon the exact
scope of work, electrical work generally accounts for approximately 8% to 12% of
the total construction cost of the Company's commercial and industrial projects
and 5% to 10% of the total construction cost of the Company's residential
projects. In recent years, the Founding Companies have experienced a growing
demand for electrical contracting services per project due to increased
electrical code requirements, demand for additional electrical capacity,
including increased capacity for computer systems, additional data cabling
requirements and the construction of smart houses with integrated systems.
 
     The overall electrical contracting industry, including commercial,
industrial and residential markets, was estimated by the U.S. Census to have
generated annual revenues in excess of $40 billion in 1992, the most recent
available U.S. Census data. Based on this Census data, the electrical
contracting industry is highly fragmented with more than 54,000 companies, most
of which are small, owner-operated businesses, performing various types of
electrical work. The Company believes there are significant opportunities for a
well-capitalized national company to provide comprehensive electrical
contracting and maintenance services and that the fragmented nature of the
electrical contracting industry will provide significant opportunities to
consolidate commercial and industrial and residential electrical contracting and
maintenance businesses.
 
     Commercial and Industrial Market. Commercial and industrial consumers of
electrical contracting and maintenance services include a broad range of
customers, including general contractors; developers; consulting engineers;
architects; owners and managers of large retail establishments, office
buildings, apartments and condominiums; theaters and restaurants; hotels and
casinos; manufacturing and processing facilities; arenas
 
                                       45
<PAGE>   51
 
and convention centers; hospitals; school districts; military and other
government agencies; airports; prisons and car lots. High-rise residential
projects are viewed as commercial rather than residential projects because the
electrical wiring methods and field skills require similar techniques.
Commercial and industrial electrical construction is most often performed by a
subcontractor for a general contractor, although an electrical contractor may
also perform services directly as a prime contractor. Generally, contracts are
obtained through a competitive bid process or on negotiated terms through
ongoing customer relationships.
 
     Typically, electrical contracting services for the industrial and
commercial market involve wiring a structure to specifications set by the
customer, increasingly with design-and-build engineering expertise provided by
the electrical contractor. The normal commercial or industrial job is wired
through pipe or conduit, which is installed through metal or concrete
structures. Some commercial and industrial contractors prefabricate certain
components offsite, at the contractor's office or at the facilities of a
subcontractor or manufacturer, and these items are transported to the job site
ready to be installed.
 
   
     From fiscal 1994 through 1996, the Founding Companies' revenues from
electrical contracting for commercial and industrial customers have grown at an
average compound annual rate of approximately 22% per year. The Company believes
that growth in the commercial and industrial market reflects a number of
factors, including (i) levels of construction and renovation activity; (ii)
regulations imposed by electric codes, which establish minimum power and wiring
requirements; (iii) safety codes mandating additional installation of smoke
detectors and the use of ground fault circuit protection devices in more
locations; (iv) revised national energy standards that dictate the use of more
energy-efficient lighting fixtures and other equipment; (v) continuing demand to
build out lease spaces in office buildings and to reconfigure space for new
tenants; (vi) increases in use of electrical power, creating needs for increased
capacity and outlets, as well as data cabling and fiber optics and (vii)
requirements of building owners and developers to facilitate marketing their
properties to tenants and buyers by installing electrical capacity in excess of
minimum code requirements.
    
 
   
     Residential Market. The residential market consists primarily of electrical
installations in new single family and low-rise multifamily residence
construction. The typical residential electrical wiring job is done with
plastic-jacketed wiring installed through wood studs. As in the commercial and
industrial market, the opportunities for design-and-build projects have grown
recently for residential contractors. The residential market, with its
repetitive floor plans, lends itself to prefabrication techniques. The use of
prefabricated components increases productivity by reducing construction time,
labor costs and skill requirements. The residential market is primarily
dependent on the number of single family and multifamily home starts, which are
in turn affected by interest rates, tax considerations and general economic
conditions. Competitive factors particularly important in the residential market
include a contractor's ability to build relationships with customers such as
large homebuilders and apartment developers by providing services in diverse
geographic markets as construction activity shifts to new locations. The
Founding Companies' residential electrical contracting revenues have grown at an
average compound annual rate of approximately 19% from fiscal 1994 through 1996.
    
 
     Residential electrical contractors with specialized expertise and the
necessary licenses are in a position to meet market demand for increasingly
complex residential electrical systems. For example, some newly constructed
homes have been designed as smart houses with integrated computer-controlled
systems wired in during construction. In addition, more stringent building and
fire codes have resulted in more complex wiring requirements for smoke detectors
and alarms.
 
STRATEGY
 
     The Company believes that its size, geographical diversity of operations,
industry relationships, expertise in specialized markets, number of licensed
electricians and access to design technology give the Company significant
competitive advantages in the electrical contracting and maintenance services
industry. Through increased size, the Company believes it will have greater
ability to compete for larger jobs that require greater technical expertise,
personnel availability and bonding capacity, to more effectively allocate and
share resources in serving customers in each of its markets and to attract,
train and retain qualified electricians. The Company also believes that
increased size will provide increased efficiency in materials purchasing,
computer
 
                                       46
<PAGE>   52
 
system development, employee benefits, bonding, insurance and financing. The
Company believes that the diversity of its operations will diminish the effects
of regional and market downturns, offer opportunities to pursue growth in its
existing markets and create a base of expertise to expand into new markets and
serve new customers.
 
     The Company plans to leverage its experienced management and extensive
relationships within the electrical contracting industry to increase its
revenues and reduce its cost infrastructure through internal growth as well as
the acquisition of additional electrical contracting businesses. The Company's
management includes a Chief Executive Officer and two Chief Operating Officers,
each with 25 years or more of experience in the electrical contracting industry.
The Company has extensive business relationships within the industry, in part
through Founding Companies that are members of the IEC. The IEC is the second
largest electrical trade organization in the U.S. and has nearly 3,000
contracting firms as members. The Company's Chief Executive Officer is a past
president of the IEC, and two founders are members of the executive committee of
the IEC. The IEC sponsors forum groups, which are discussion groups of members
of the IEC that foster the sharing of best business practices. The Founding
Companies are members of the IEC and other trade organizations, and the Company
intends to expand the practice of sharing best practices among the Founding
Companies and with future acquisitions.
 
     The Company's goal is to become a leading national provider of electrical
services by improving its operations, expanding its business and markets through
internal growth and pursuing an aggressive acquisition strategy.
 
     Operating Strategy. The Company believes there are significant
opportunities to increase revenues and profitability of the Founding Companies
and subsequently acquired businesses. The key elements of the Company's
operating strategy are:
 
          Share Information, Technical Capabilities and Best Practices. The
     Company believes it will be able to expand the services it offers in its
     local markets by leveraging the specialized technical and marketing
     strengths of individual Founding Companies. The Company will identify and
     share best practices that can be successfully implemented throughout its
     operations. The Company intends to use the computer-aided-design technology
     and expertise of certain of the Founding Companies to bid for more
     design-and-build projects and to assist customers in value engineering and
     creating project documents. The Company believes that its increased size,
     capital and workforce will permit it to pursue projects that require
     greater design and performance capabilities and the ability to meet
     accelerated timetables.
 
          Expand Scope of Maintenance and Specialized Services. The Company
     intends to further develop its long-term and per call maintenance service
     operations, which generally realize higher gross margins and provide
     recurring revenues that are relatively independent of levels of
     construction activity. The Company also believes that certain specialized
     businesses currently offered by only a few of the Founding Companies can be
     expanded throughout the Company and in some cases can provide higher
     margins. Through sharing of expertise and specialized licenses and the
     ability to demonstrate a safety record in specialized markets served by the
     Founding Companies, the Company intends to expand its presence and
     profitability in markets where it previously relied on subcontractors.
 
          Establish National Market Coverage. The Company believes that the
     growth of many of the Founding Companies has been restricted due to the
     geographic limitations of existing operations and that the Company's broad
     geographic coverage will increase internal growth opportunities. The
     Company intends to leverage its geographic diversity to bid for additional
     business from existing customers that operate on a regional and national
     basis, such as developers, contractors, homebuilders and owners of national
     chains. The Company believes that significant demand exists from such
     companies to utilize the services of a single electrical contracting and
     maintenance service provider and existing local and regional relationships
     can be expanded as the Company develops a nationwide network.
 
          Operate on Decentralized Basis. The Company believes that, while
     maintaining strong operating and financial controls, a decentralized
     operating structure will retain the entrepreneurial spirit present in each
     of the Founding Companies. The Company also will be structured to allow it
     to capitalize on the
 
                                       47
<PAGE>   53
 
     considerable local and regional market knowledge and customer relationships
     possessed by each Founding Company, as well as companies that may be
     acquired in the future. By maintaining a local and regional focus in each
     of its markets, the Company believes it will be able to build relationships
     with general contractors and other customers, address design preferences
     and code requirements, respond quickly to customer demands for
     higher-margin renovation and upgrade projects and adjust to local
     conditions.
 
   
          Attract and Retain Quality Employees. The Company believes that the
     ability to attract and retain qualified electricians is a critical
     competitive factor and that the Acquisitions and the Offerings will provide
     competitive advantages in this regard. The Company intends to attract and
     develop skilled employees by extending active recruiting and training
     programs, offering stock-based compensation for key employees, and offering
     expanded career paths and more stable income through the larger public
     company. The Company believes that this ability will allow it to increase
     efficiency and pursue additional customer relationships.
    
 
   
          Achieve Operating Efficiencies. Certain administrative functions will
     be centralized following the Offerings. In addition, by combining
     overlapping operations of certain of the Founding Companies, the Company
     expects to realize savings in overhead and other expenses. The Company
     intends to use its increased purchasing power to gain volume discounts in
     areas such as electrical materials, vehicles, advertising, bonding,
     employee benefits and insurance. The Company will seek to realize cost
     savings and other benefits by the sharing of purchasing, pricing, bidding
     and other business practices and the sharing of licenses. The Company
     intends to further develop and extend the use of computer systems to
     facilitate communication among the Founding Companies. At some locations,
     the larger combined workforce will provide additional staffing flexibility.
    
 
     Acquisition Strategy. The Company believes that, due to the highly
fragmented nature of the electrical contracting and maintenance services
industry, it has significant opportunities to pursue its acquisition strategy.
The Company intends to focus on acquiring companies with management philosophies
based on both an entrepreneurial attitude as well as a willingness to learn and
share improved business practices through open communications. The Company
believes that many electrical contracting and service businesses that lack the
capital necessary to expand operations will become acquisition candidates. For
these acquisition candidates, the Company will provide (i) information on best
practices, (ii) expertise in expanding in specialized markets, (iii) the
opportunity to focus on customers rather than administration, (iv) national name
recognition, (v) increased liquidity and (vi) the opportunity for a continued
role in management. The Founding Companies participate in professional
associations such as the IEC and Associated Builders and Contractors, and the
Company intends to continue these relationships, in part to assist in
identifying attractive acquisition candidates. Other key elements of the
Company's acquisition strategy are:
 
          Enter New Geographic Markets. The Company will pursue acquisitions
     that are located in new geographic markets, are financially stable and have
     the customer base necessary to integrate with or complement its existing
     business. The Company also expects that increasing its geographic diversity
     will allow it to better serve an increasingly nationwide base of customers
     and further reduce the impact on the Company of local and regional economic
     cycles, as well as weather-related or seasonal variations in business.
 
   
          Expand Within Existing Markets. Once the Company has entered a market,
     it will seek to acquire other well-established electrical contracting and
     maintenance businesses operating within that region, including "tuck-in"
     acquisitions of smaller companies. The Company believes that tuck-in
     acquisitions afford the opportunity to improve its overall cost structure
     through the integration of such acquisitions into existing operations as
     well as to increase revenues through access to additional specialized
     markets, such as heavy industrial markets. Despite the integration
     opportunities afforded by such tuck-in acquisitions, the Company intends to
     maintain existing business names and identities to retain goodwill for
     marketing purposes.

COMPANY OPERATIONS
 
     The Company offers a broad range of electrical contracting services,
including installation and design, for both new and renovation projects in the
commercial, industrial and residential markets. The Company also offers
long-term and per call maintenance services, which generally provide recurring
revenues that are relatively independent of levels of construction activity.
 
     In certain markets the Company offers design-and-build expertise and
specialized services, which typically require specific skills and equipment and
provide higher margins than general electrical contracting and maintenance
services. The Company also acts as a subcontractor for a variety of national,
regional and local builders in the installation of electrical and other systems.
 
     Commercial and Industrial. New commercial and industrial work begins with
either a design request or engineer's plans from the owner or general
contractor. Initial meetings with the parties allow the contractor to prepare
preliminary and then more detailed design specifications, engineering drawings
and cost estimates. Once a project is awarded, it is conducted in scheduled
phases, and progress billings are rendered to the owner for payment, less a
retainage of 5% to 10% of the construction cost of the project. Actual field
work (ordering of equipment and materials, fabrication or assembly of certain
components, delivery of materials and components to the job site, scheduling of
work crews and inspection and quality control) is coordinated during these
phases. The Company generally provides the materials to be installed as a part
of these contracts, which vary significantly in size from a few hundred dollars
to several million dollars and vary in duration from less than a day to more
than a year.
 
     Residential. New residential installations begin with a builder providing
architectural or mechanical drawings for the residences within the tract being
developed. The Company typically submits a bid or contract proposal for the
work. Company personnel analyze the plans and drawings and estimate the
equipment, materials and parts and the direct and supervisory labor required for
the project. The Company delivers a written bid or negotiates an arrangement for
the job. The installation work is coordinated by the Company's field supervisors
along with the builder's personnel. Payments for the project are generally
obtained within 30 days, at which time any mechanics' and materialmen's liens
securing such payments are released. Interim payments are often obtained to
cover labor and materials costs on larger projects.
 
   
     Maintenance Services. The Company's maintenance services are supplied on a
long-term and per call basis. The Company's long-term maintenance services are
provided through service contracts that require the customer to pay an annual or
semiannual fee for periodic diagnostic services at a specific discount from
standard prices for repair and replacement service. The Company's per call
maintenance services are initiated when a customer requests emergency repair
service or the Company calls the client to schedule periodic maintenance work.
Service technicians are scheduled for the call or routed to the customer's
residence or business by the dispatcher. Service personnel work out of the
Company's service vehicles, which carry an inventory of equipment, tools, parts
and supplies needed to complete the typical variety of jobs. The technician
assigned to a service call travels to the residence or business, interviews the
customer, diagnoses the problem, prepares and discusses a price quotation,
performs the work and often collects payment from the customer. Most work is
warrantied for one year. During the year ended September 30, 1997, the Company
had $35.8 million in revenues for periodic maintenance services provided under
existing service contracts and for emergency or other routine service calls.
    
 
   
     Major Customers. The Company has a diverse customer base, with no single
customer accounting for more than 5% of the Company's pro forma combined 1997
revenues. As a result of emphasis on quality and worker reliability, management
and a dedicated sales and work force at the Founding Companies have been
responsible for developing and maintaining successful relationships with key
customers. Customers of the Founding Companies generally include general
contractors; developers; consulting engineers; architects; owners and managers
of large retail establishments, office buildings, apartments and condominiums,
theaters and restaurants; hotels and casinos; manufacturing and processing
facilities; arenas and convention centers; hospitals; school districts; military
and other government agencies; airports; prisons and car lots. The Company
intends to continue its emphasis on developing and maintaining relationships
with its customers by providing superior, high-quality service.
    
 
                                       49
<PAGE>   55
 
     Employee Screening, Training and Development. The Company is committed to
providing the highest level of customer service through the development of a
highly trained workforce. Employees are encouraged to complete a progressive
training program to advance their technical competencies and to ensure that they
understand and follow the applicable codes, the Company's safety practices and
other internal policies. The Company supports and funds continuing education for
its employees, as well as apprenticeship training for its technicians under the
Bureau of Apprenticeship and Training of the Department of Labor and similar
state agencies. Employees who train as apprentices for four years may seek to
become journeymen electricians and, after additional years of experience, master
electricians. The Company pays progressive increases in compensation to
employees who acquire such additional training, and more highly trained
employees serve as foremen, estimators and project managers. The Company's
master electricians are licensed in one or more cities or other jurisdictions in
order to obtain the permits required in the Company's business, and certain
master electricians have also obtained specialized licenses in areas such as
security systems and fire alarm installation. In some areas, licensing boards
have set continuing education requirements for maintenance of licenses. Because
of the lengthy and difficult training and licensing process for electricians,
the Company believes that the number, skills and licenses of its employees
constitute a competitive strength in the industry.
 
     The Company actively recruits and screens applicants for its technical
positions and has established programs in some locations to recruit apprentice
technicians directly from high schools and vocational-technical schools. Prior
to employment, the Company will make an assessment of the technical competence
level of all potential new employees, confirm background references, conduct
random drug testing and check criminal and driving records.
 
   
     Purchasing. As a result of economies of scale derived through the
Acquisitions and the Company's in-house supply operations, the Company believes
it will be able to purchase equipment, parts and supplies at discounts to
historical levels. In addition, as a result of the Company's size, it believes
it will also lower its costs for (i) the purchase or lease and maintenance of
vehicles; (ii) bonding, casualty and liability insurance; (iii) health insurance
and related benefits; (iv) retirement benefits administration; (v) office and
computer equipment; (vi) marketing and advertising; (vii) long distance services
and (viii) a variety of accounting, financial management and legal services.
    
 
     Substantially all the equipment and component parts the Company sells or
installs are purchased from manufacturers and other outside suppliers. The
Company is not materially dependent on any of these outside sources.
 
MANAGEMENT INFORMATION AND CONTROLS
 
     The Company intends to centralize its consolidated accounting and financial
reporting activities at its operational headquarters in Houston, Texas, while
basic accounting activities will be conducted at the operating level. The
Company believes that its current information systems hardware and software are
adequate to meet current needs for financial reporting, internal management
control and other necessary information and the needs of newly acquired
corporations.
 
PROPERTY AND EQUIPMENT
 
   
     The Company operates a fleet of approximately 850 owned and leased service
trucks, vans and support vehicles. It believes these vehicles generally are
adequate for the Company's current operations.
    
 
   
     At September 30, 1997, the Company maintained offices at 48 locations. All
of the Company's facilities are leased. The Company's corporate headquarters are
located in Houston, Texas. The paragraphs below summarize the Company's primary
office and operating facilities.
    
 
     The Company's primary warehouses, sales facilities and administrative
offices are as follows, subject to consolidation of certain facilities to
achieve operating efficiencies and subject to the execution of leases with

     In addition to the facilities listed above, the Company may operate on a
short-term basis in other locations as may be required from time to time to
perform its contracts. Upon the consummation of the Offerings, the Company will
lease its principal and administrative offices in Houston, Texas and is
currently in the process of obtaining office space for this purpose.
    
 
     The Company believes that its properties are generally adequate for its
present needs. Furthermore, the Company believes that suitable additional or
replacement space will be available as required.
 
COMPETITION
 
   
     The electrical contracting industry is highly fragmented and competitive.
Most of the Company's competitors are small, owner-operated companies that
typically operate in a limited geographic area. There are few public companies
focused on providing electrical contracting services. In the future, competition
may be encountered from new entrants, such as public utilities and other
companies attempting to consolidate electrical contracting service companies.
Competitive factors in the electrical contracting industry include (i) the
availability of qualified and licensed electricians, (ii) safety record, (iii)
cost structure, (iv) relationships with customers, (v) geographic diversity,
(vi) ability to reduce project costs, (vii) access to technology, (viii)
experience in specialized markets and (ix) ability to obtain bonding.
    
 
REGULATIONS
 
     The Company's operations are subject to various federal, state and local
laws and regulations, including (i) licensing requirements applicable to
electricians; (ii) building and electrical codes; (iii) regulations relating to
consumer protection, including those governing residential service agreements
and (iv) regulations relating to worker safety and protection of the
environment. The Company believes it has all required licenses to conduct its
operations and is in substantial compliance with applicable regulatory
requirements. Failure of the Company to comply with applicable regulations could
result in substantial fines or revocation of the Company's operating licenses.
 
     Many state and local regulations governing electricians require permits and
licenses to be held by individuals. In some cases, a required permit or license
held by a single individual may be sufficient to authorize specified activities
for all the Company's electricians who work in the state or county that issued
the permit or license. The Company intends to implement a policy to ensure that,
where possible, any such permits or licenses that may be material to the
Company's operations in a particular geographic region are held by at least two
Company employees within that region.
 
LITIGATION
 
     Each of the Founding Companies has, from time to time, been a party to
litigation arising in the normal course of its business, most of which involves
claims for personal injury or property damage incurred in connection with its
operations. Management believes that none of these actions will have a material
adverse effect on the financial condition or results of operations of the
Company.
 
EMPLOYEES
 
   
     At September 30, 1997, the Company had approximately 3,550 employees. The
Company is not a party to any collective bargaining agreements. The Company
believes that its relationship with its employees is satisfactory.

EMPLOYMENT AGREEMENTS
 
   
     The Company will enter into employment agreements with each executive
officer of the Company which prohibits such officer from disclosing the
Company's confidential information and trade secrets and generally restricts
these individuals from competing with the Company for a period of two years
after the date of the termination of employment with the Company. Each of the
agreements has an initial term of five years and provides for annual extensions
at the end of its initial term, subject to the parties' mutual agreement, and is
terminable by the Company for "cause" upon ten days' written notice and without
"cause" by either party upon thirty days' written notice. The employment
agreements provide that the Company shall pay each executive officer the annual
salary set forth above under "-- Executive Compensation," which salary may be
increased by the Board of Directors. Such agreements also provide that each
executive officer will be reimbursed for out-of-pocket business expenses and
shall be eligible to participate in all benefit plans and programs as are
maintained from time to time by the Company. All employment agreements provide
that if the officer's employment is terminated by the Company without "cause" or
is terminated by the officer for "good reason," the officer will be entitled to
receive a lump sum severance payment at the effective time of termination equal
to the base salary (at the rate then in effect) for the greater of (i) the time
period remaining under the term of the agreement or (ii) one year. In addition,
the time period during which such officer is restricted from competing with the
Company will be shortened from two years to one year.
    
 
   
     The employment agreements contain certain provisions concerning a
change-in-control of the Company, including the following: (i) in the event the
officer's employment is terminated within two years following the change in
control by the Company other than for "cause" or by the officer for "good
reason," or the officer is terminated by the Company within three months prior
to the change in control at the request of the acquirer in anticipation of the
change in control, the officer will be entitled to receive a lump sum severance
amount equal to three years' base salary and the provisions which restrict
competition with the Company shall not apply; (ii) in any change-of-control
situation, the officer may elect to terminate his employment by giving five
business days' written notice prior to the closing of the transaction giving
rise to the change-in-control, which will be deemed a termination of employment
by the Company without "cause," and the provisions of the employment agreement
governing the same will apply, except that the severance amount otherwise
payable shall be doubled (but not to exceed six times the officer's base pay)
(if the successor does not give written notice of its acceptance of the
Company's obligations under the employment agreement at least ten business days
prior to the anticipated closing date, the severance amount shall be tripled,
but not to exceed nine times base salary) and provisions which restrict
competition with the Company shall not apply; and (iii) if any payment to the
officer is subject to the 20% excise tax on excess parachute payments, the
officer shall be made "whole" on a net aftertax basis. A change in control is
generally defined to occur upon (i) the acquisition by any person of 20% or more
of the total voting power of the outstanding securities of the Company, (ii) the
first purchase pursuant to a tender or exchange offer for Common Stock, (iii)
the approval of certain mergers, sale of substantially all the assets, or
dissolution of the Company or (iv) a change in a majority of the members of the
Company's Board of Directors.
    
 
   
     In general, a "parachute payment" is any "payment" made by the Company in
the nature of compensation that is contingent on a change in control of the
Company and includes the present value of the accelerations of vesting and the
payment of options and other deferred compensation amounts upon a change in
control. If the aggregate present value of the parachute payments to certain
individuals, including officers, equals or exceeds three times that individual's
"base amount" (generally, the individual's average annual compensation from the
Company for the five calendar years ending before the date of the change in
control), then all parachute amounts in excess of the base amount are "excess"
parachute payments. An individual will
    
 
                                       56
<PAGE>   62
 
   
be subject to a 20% excise tax on excess parachute amounts and the Company will
not be entitled to a tax deduction for such payments.
    
 
1997 STOCK PLAN
 
   
     The Company's 1997 Stock Plan was adopted by the Board of Directors and
stockholders in October 1997. The purpose of the 1997 Stock Plan is to provide
officers, employees and consultants with additional incentives by increasing
their ownership interests in the Company. Individual awards under the 1997 Stock
Plan may take the form of one or more of: (i) either incentive stock options
("ISOs") or non-qualified stock options ("NQSOs"); (ii) stock appreciation
rights; (iii) restricted or phantom stock; (iv) bonus stock awards; (v) awards
not otherwise provided for, the value of which is based in whole or in part upon
the value of the Common Stock and (vi) cash awards that may or may not be based
on the achievement of performance goals, including goals related to one or more
of the following: cash flow, return on equity, sales, profit margin, earnings
per share and stock price.
    
 
   
     The Compensation Committee or the Company's President, to the extent such
duties are delegated to him by the Compensation Committee, will administer the
1997 Stock Plan and select the individuals who will receive awards and establish
the terms and conditions of those awards. The Compensation Committee will not be
eligible to receive awards under the plan, and the President will not have the
authority to make grants to officers or directors of the Company. The maximum
number of shares of Common Stock that may be subject to outstanding awards,
determined immediately after the grant of any award, may not exceed the greater
of 3,500,000 shares or 15% of the aggregate number of shares of Common Stock
outstanding; provided, however, that ISOs may not be granted with respect to
more than 1,000,000 shares. Shares of Common Stock which are attributable to
awards which have expired, terminated or been canceled or forfeited are
available for issuance or use in connection with future awards. The maximum
number of shares of Common Stock with respect to which any person may receive
options and stock appreciation rights in any year is 250,000 shares and the
maximum value of any other amount may not exceed $4 million as of the date of
its grant.
    
 
   
     The 1997 Stock Plan will remain in effect for ten years, unless earlier
terminated by the Board of Directors. The 1997 Stock Plan may be amended by the
Board of Directors or the Compensation Committee without the consent of the
stockholders of the Company, except that any amendment will be subject to
stockholder approval if required by any federal or state law or regulation or by
the rules of any stock exchange or automated quotation system on which the
Common Stock may then be listed or quoted.
    
 
   
     NQSOs to purchase a total of 150,000 shares of Common Stock have been
granted to each of Mr. Wise and Mr. Wombell. In addition, at the consummation of
the Offerings, NQSOs to purchase approximately 2,328,600 shares will be granted
to other key employees of the Company and to employees of the Founding
Companies. Each of the foregoing options will have an exercise price equal to
the initial public offering price of the shares offered hereby, other than the
options granted to Messrs. Wise and Wombwell, which have been granted with
exercise price equal to 60% of the initial public offering price per share. Each
of these options will vest at the rate of 20% per year, commencing on the first
anniversary of grant and will expire at the earliest of (i) ten years from the
date of grant, (ii) three months following termination of employment, other than
due to death or disability or (iii) one year following a termination of
employment due to death or disability.
    
 
1997 DIRECTORS STOCK PLAN
 
   
     The Company's 1997 Directors Stock Plan was adopted by the Board of
Directors and approved by the Company's stockholders in October 1997. The
Directors Plan provides for (i) the automatic grant to each non-employee
director serving at the consummation of the Offerings of an option to purchase
5,000 shares, (ii) the automatic grant to each non-employee director of an
option to purchase 5,000 shares upon such person's initial election as a
director and (iii) an automatic annual grant to each non-employee director of an
option to purchase 5,000 shares on each September 30th on which such director
remains a non-employee director. All options will have an exercise price per
share equal to the fair market value of the Common Stock on the date of grant,
will vest over five years at the rate of 20% per year and will expire on the
earliest of (i) ten years from the date of grant, (ii) three months after
termination of service as a director, due to death or
    
 
                                       57
<PAGE>   63

                              CERTAIN TRANSACTIONS
 
ORGANIZATION OF THE COMPANY
 
   
     The Company was founded in June 1997 by C. Byron Snyder. In connection with
the formation of IES, IES issued to Mr. Snyder, the Snyder Children's Trust and
D. Merril Cummings a total of 2,329,600 shares of Common Stock for nominal
consideration. Mr. Snyder is currently president and a director of the Company.
The trustee of the Snyder Children's Trust is an independent third party not
subject to control by Mr. Snyder. In September 1997, IES issued an additional
442,589 shares to Mr. Snyder and such trust. The value of the Common Stock
issued to Mr. Snyder was estimated at $9.10 per share and has been reflected as
a non-cash compensation charge in the IES financial statements. In October 1997,
Mr. Snyder exchanged 2,655,709 shares of Common Stock for an equal number of
shares of Restricted Common Stock. Mr. Snyder has agreed to advance whatever
funds are necessary to effect the Acquisitions and the Offerings. As of
September 30, 1997, Mr. Snyder had outstanding advances to the Company in the
aggregate amount of approximately $1.6 million at September 30, 1997, all of
which are non-interest-bearing. All of Mr. Snyder's advances will be repaid from
the net proceeds of the Offerings.
    
 
   
     The Company has issued a total of 1,396,602 shares of Common Stock at $.01
per share to various members of management, including: Mr. Pollock -- 465,914
shares, Mr. Mills -- 232,957 shares, Mr. Mueller -- 232,957 shares, Mr.
Wise -- 100,000 shares, Mr. Wombwell -- 100,000 shares and other key
employees -- 264,774 shares. The Company also granted options to purchase 5,000
shares of Common Stock under the Directors Plan, effective upon the consummation
of the Offerings, to the non-employee directors of the Company upon the closing
of the Offerings.
    
 
   
     Simultaneously with the closing of the Offerings, the Company will acquire
by stock purchase all the issued and outstanding capital stock and other equity
interests of the Founding Companies, at which time each Founding Company will
become a wholly owned subsidiary of the Company. The Acquisitions Consideration
was negotiated by the parties and was based primarily upon the pro forma
adjusted net income of each Founding Company. The Acquisitions Consideration
consists of (i) an estimated $57.5 million in cash (subject to adjustment based
on the initial public offering price) and (ii) 12,313,025 shares of Common
Stock. In addition, the Company intends to repay approximately $6.4 million of
the historical indebtedness of the Founding Companies. In connection with the
Acquisitions, owners of certain of the Founding Companies will receive the Owner
Amounts, in the amounts set forth below. The Company will incur approximately
$18.2 million in indebtedness to fund the Owner Amounts.
    
 
     The consummation of each Acquisition is subject to customary conditions.
These conditions include, among others, the accuracy of the representations and
warranties by the Founding Companies, their stockholders and the Company; the
performance by each of the parties of their respective covenants; and the
nonexistence of a material adverse change in the results of operations,
financial condition or business of each Founding Company. There can be no
assurance that the conditions to closing of the Acquisitions will be satisfied
or waived or that the acquisition agreements will not be terminated prior to
consummation.
 
   
     The following table sets forth for each Founding Company (i) the
approximate portion of the Acquisitions Consideration to be paid to the
stockholders of each of the Founding Companies in cash and in shares of Common
Stock, which cash is subject to adjustments based on the initial public offering
price of the Common Stock offered hereby and (ii) the total debt which would
have been assumed by the Company as of

one-half of one vote for each share held on all other matters on which they are
entitled to vote. Holders of Restricted Common Stock are not entitled to vote on
the election of any other directors. Only the holder of the Restricted Common
Stock may remove the director such holder is entitled to elect.
 
   
     Subject to the rights of any then outstanding shares of preferred stock,
holders of Common Stock and Restricted Common Stock are together entitled to
participate pro rata in such dividends as may be declared in the discretion of
the Board of Directors out of funds legally available therefor. Holders of
Common Stock and Restricted Common Stock together are entitled to share ratably
in the net assets of the Company upon liquidation after payment or provision for
all liabilities and any preferential liquidation rights of any preferred stock
then outstanding. Holders of Common Stock and holders of Restricted Common Stock
have no preemptive rights to purchase shares of stock of the Company. Shares of
Common Stock are not subject to any redemption provisions and are not
convertible into any other securities of the Company. Shares of Restricted
Common Stock are not subject to any redemption provisions and are convertible
into Common Stock as described below. All outstanding shares of Common Stock and
Restricted Common Stock are, and the shares of Common Stock to be issued
pursuant to the Offering and the Acquisitions will be, upon payment therefor,
fully paid and non-assessable.
    
 
   
     Each share of Restricted Common Stock will automatically convert to Common
Stock on a share-for-share basis (i) in the event of a disposition of such share
of Restricted Common Stock by the holder thereof (other than a distribution by a
holder to its partners or beneficial owners, or a transfer to a related party of
such holders (as defined in Sections 267, 707, 318 and/or 4946 of the Internal
Revenue Code of 1986, as amended)), (ii) in the event any person acquires
beneficial ownership of 15% or more of the total number of outstanding shares of
Common Stock or (iii) in the event any person offers to acquire 15% or more of
the total number of outstanding shares of Common Stock.
    
 
     The Company intends to make application to list the Common Stock on the
NYSE under the symbol "IEE." The Restricted Common Stock will not be listed on
any exchange.
 
PREFERRED STOCK
 
     The preferred stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series. Subject to the provisions
of the Company's Amended and Restated Certificate of
 
                                       63
<PAGE>   69
 
   
Incorporation and limitations prescribed by law, the Board of Directors is
expressly authorized to adopt resolutions to issue the shares, to fix the number
of shares and to change the number of shares constituting any series, and to
provide for or change the voting powers, designations, preferences and relative,
participating, optional or other special rights, qualifications, limitations or
restrictions thereof, including dividend rights (including whether dividends are
cumulative), dividend rates, terms of redemption (including sinking fund
provisions), redemption prices, conversion rights and liquidation preferences of
the shares constituting any class or series of the preferred stock, in each case
without any further action or vote by the stockholders. The Company has no
current plans to issue any shares of preferred stock of any class or series.
    
 
     One of the effects of undesignated preferred stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of preferred stock pursuant to the Board of Directors'
authority described above may adversely affect the rights of the holders of
Common Stock. For example, preferred stock issued by the Company may rank prior
to the Common Stock as to dividend rights, liquidation preference or both, may
have full or limited voting rights and may be convertible into shares of Common
Stock. Accordingly, the issuance of shares of preferred stock may discourage
bids for the Common Stock at a premium or may otherwise adversely affect the
market price of the Common Stock.
 
STATUTORY BUSINESS COMBINATION PROVISION
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("Section 203"). Section 203 provides, with certain
exceptions, that a Delaware corporation may not engage in any of a broad range
of business combinations with a person or an affiliate, or associate of such
person, who is an "interested stockholder" for a period of three years from the
date that such person became an interested stockholder unless: (i) the
transaction resulting in a person becoming an interested stockholder, or the
business combination, is approved by the Board of Directors of the corporation
before the person becomes an interested stockholder, (ii) the interested
stockholder acquired 85% or more of the outstanding voting stock of the
corporation in the same transaction that makes such person an interested
stockholder (excluding shares owned by persons who are both officers and
directors of the corporation, and shares held by certain employee stock
ownership plans) or (iii) on or after the date the person becomes an interested
stockholder, the business combination is approved by the corporation's board of
directors and by the holders of at least 66% of the corporation's outstanding
voting stock at an annual or special meeting, excluding shares owned by the
interested stockholder. Under Section 203, an "interested stockholder" is
defined as any person who is (i) the owner of 15% or more of the outstanding
voting stock of the corporation or (ii) an affiliate or associate of the
corporation and who was the owner of 15% or more of the outstanding voting stock
of the corporation at any time within the three-year period immediately prior to
the date on which it is sought to be determined whether such person is an
interested stockholder.
 
     A corporation may, at its option, exclude itself from the coverage of
Section 203 by including in its certificate of incorporation or bylaws by action
of its stockholders to exempt itself from coverage. The Company has not adopted
such an amendment to its Amended and Restated Certificate of Incorporation or
Bylaws.
 
LIMITATION ON DIRECTORS' LIABILITIES
 
   
     Pursuant to the Company's Amended and Restated Certificate of Incorporation
and under Delaware law, directors of the Company are not liable to the Company
or its stockholders for monetary damages for breach of fiduciary duty, except
for liability in connection with a breach of the duty of loyalty, for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for dividend payments or stock repurchases illegal under
Delaware law or any transaction in which a director has derived an improper
personal benefit. The Company has entered into indemnification agreements with
its directors and executive officers which indemnify such person to the fullest
extent permitted by its Amended and Restated Certificate of Incorporation, its
Bylaws and the Delaware General Corporation Law. The Company also intends to
obtain
    
 
                                       64
<PAGE>   70
 
   
directors' and officers' liability insurance. The foregoing provisions may
extend to liabilities arising due to violations of the federal securities laws.
    
 
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS
 
     The Company's Amended and Restated Certificate of Incorporation and Bylaws
include provisions that may have the effect of discouraging, delaying or
preventing a change in control of the Company or an unsolicited acquisition
proposal that a stockholder might consider favorable, including a proposal that
might result in the payment of a premium over the market price for the shares
held by stockholders. These provisions are summarized in the following
paragraphs.
 
     Classified Board of Directors. The Amended and Restated Certificate of
Incorporation provides for the Board of Directors to be divided into three
classes of directors serving staggered three-year terms. The classification of
the Board of Directors has the effect of requiring at least two annual
stockholder meetings, instead of one, to replace a majority of members of the
Board of Directors.
 
     Supermajority Voting. The Amended and Restated Certificate of Incorporation
requires the approval of the holders of at least 75% of the then outstanding
shares of the Company's capital stock entitled to vote thereon and the approval
of the holders of at least 75% of the then outstanding shares of each class of
stock of the Company voting separately as a class on, among other things,
certain amendments to the Amended and Restated Certificate of Incorporation. The
Board of Directors may amend, alter, change or repeal any bylaws without the
assent or vote of the stockholders, but any such bylaws may be altered, amended
or repealed upon the affirmative vote of at least 66 2/3% of the stock entitled
to vote thereon.
 
   
     Authorized but Unissued or Undesignated Capital Stock. The Company's
authorized capital stock will consist of 100,000,000 shares of Common Stock,
including 2,655,709 shares of Restricted Common Stock, and 10,000,000 shares of
preferred stock. After the Offerings, the Company will have outstanding
23,365,336 shares of Common Stock (assuming the Underwriters' over-allotment
options are not exercised). The authorized but unissued (and in the case of
preferred stock, undesignated) stock may be issued by the Board of Directors in
one or more transactions. In this regard, the Company's Amended and Restated
Certificate of Incorporation grants the Board of Directors broad power to
establish the rights and preferences of authorized and unissued preferred stock.
The issuance of shares of preferred stock pursuant to the Board of Directors'
authority described above could decrease the amount of earnings and assets
available for distribution to holders of Common Stock and adversely affect the
rights and powers, including voting rights, of such holders and may also have
the effect of delaying, deferring or preventing a change in control of the
Company. The Board of Directors does not currently intend to seek stockholder
approval prior to any issuance of preferred stock, unless otherwise required by
law.
    
 
     Special Meeting of Stockholders. The Bylaws provide that special meetings
of stockholders of the Company may only be called by the Chairman of the Board
of Directors upon the written request of the Board of Directors pursuant to a
resolution approved by a majority of the Board of Directors.
 
     Stockholder Action by Written Consent. The Amended and Restated Certificate
of Incorporation and Bylaws generally provide that any action required or
permitted by the stockholders of the Company must be effected at a duly called
annual or special meeting of the stockholders and may not be effected by any
written consent of the stockholders.
 
     Notice Procedures. The Bylaws establish advance notice procedures with
regard to stockholder proposals relating to the nomination of candidates for
election as director, the removal of directors and amendments to the Amended and
Restated Certificate of Incorporation or Bylaws to be brought before annual
meetings of stockholders of the Company. These procedures provide that notice of
such stockholder proposals must be timely given in writing to the Secretary of
the Company prior to the annual meeting. Generally, to be timely, notice must be
received at the principal executive offices of the Company not less than 80 days
prior to an annual meeting (or if fewer than 90 days' notice or prior public
disclosure of the date of the annual meeting is given or made by the Company,
not later than the tenth day following the date on which the notice of the date
of the annual meeting was mailed or such public disclosure was made). The notice
must contain certain
 
                                       65
<PAGE>   71
 
information specified in the Bylaws, including a brief description of the
business desired to be brought before the annual meeting and certain information
concerning the stockholder submitting the proposal.
 
     Charter Provisions Relating to Rights Plan. The Amended and Restated
Certificate of Incorporation authorizes the Board of Directors of the Company to
create and issue rights (the "Rights") entitling the holders thereof to purchase
from the Company shares of capital stock or other securities. The times at
which, and the terms upon which, the Rights are to be issued may be determined
by the Board of Directors and set forth in the contracts or instruments that
evidence the Rights. The authority of the Board of Directors with respect to the
Rights includes, but is not limited to, the determination of (i) the initial
purchase price per share of the capital stock or other securities of the Company
to be purchased upon exercise of the Rights, (ii) provisions relating to the
times at which and the circumstances under which the Rights may be exercised or
sold or otherwise transferred, either together with or separately from, any
other securities of the Company, (iii) antidilutive provisions which adjust the
number or exercise price of the Rights or amount or nature of the securities or
other property receivable upon exercise of the Rights, (iv) provisions which
deny the holder of a specified percentage of the outstanding securities of the
Company the right to exercise the Rights and/or cause the Rights held by such
holder to become void, (v) provisions which permit the Company to redeem the
Rights and (vi) the appointment of a rights agent with respect to the Rights. If
authorized by the Board of Directors, the Rights would be intended to protect
the Company's stockholders from certain non-negotiated takeover attempts which
present the risk of a change of control on terms which may be less favorable to
the Company's stockholder than would be available in a transaction negotiated
with and approved by the Board of Directors. The Board of Directors believes
that the interests of the stockholders generally are best served if any
acquisition of the Company or a substantial percentage of the Company's Common
Stock results from arm's-length negotiations and reflects the Board of
Directors' careful consideration of the proposed terms of a transaction. In
particular, the Rights if issued would be intended to help (i) reduce the risk
of coercive two-tiered, front-end loaded or partial offers which may not offer
fair value to all stockholders of the Company, (ii) deter market accumulators
who through open market or private purchases may achieve a position of
substantial influence or control without paying to stockholders a fair control
premium and (iii) deter market accumulators who are simply interested in putting
the Company "in play."
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is Harris Trust and
Savings Bank.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     The market price of the Common Stock could be adversely affected by the
sale of substantial amounts of Common Stock in the public market. All of the
7,000,000 shares sold in the Offerings, except for shares acquired by affiliates
of the Company, will be freely tradeable. Simultaneously with the closing of the
Offerings, the stockholders of the Founding Companies will receive, in the
aggregate, 12,313,025 shares of Common Stock as a portion of the consideration
for their businesses. Certain other stockholders of the Company will hold, in
the aggregate, an additional 1,396,602 shares of Common Stock and 2,655,709
shares of Restricted Common Stock. None of these 16,365,336 shares was issued in
a transaction registered under the Securities Act, and, accordingly, such shares
may not be sold except in transactions registered under the Securities Act or
pursuant to an exemption from registration, including the exemptions contained
in Rules 144 and 701 under the Securities Act.
    
 
   
     In general, under Rule 144 as currently in effect, a person, or persons
whose shares are aggregated, who has beneficially owned his or her shares for at
least one year but not more than two years, or a person who may be deemed an
"affiliate" of the Company who has beneficially owned shares for at least one
year, would be entitled to sell within any three month period a number of shares
that does not exceed the greater of 1% of the then outstanding shares of the
Common Stock or the average weekly trading volume of the Common Stock during the
four calendar weeks preceding the date on which notice of the proposed sale is
sent to the Securities and Exchange Commission. Sales under Rule 144 are also
subject to certain manner of sale provisions, notice requirements and the
availability of current public information about the Company. A person who is
not
    
 
                                       66
<PAGE>   72
 
deemed to have been an affiliate of the Company at any time for 90 days
preceding a sale and who has beneficially owned his shares for at least two
years would be entitled to sell such shares under Rule 144 without regard to the
volume limitations, manner of sale provisions, notice requirements or the
availability of current public information about the Company.
 
   
     In general, under Rule 701 under the Securities Act, any employee, officer,
or director of or consultant to the Company who purchased his or her shares
pursuant to a written compensatory plan or contract is entitled to rely on the
resale provisions of Rule 701. Such provisions permit nonaffiliates to sell
their Rule 701 shares without having to comply with the public information,
holding period, volume limitation, or notice provisions of Rule 144 and permit
affiliates to sell their Rule 701 shares without having to comply with the Rule
144 holding period restrictions, in each case commencing 90 days after the
commencement of the Offerings.
    
 
   
     The Company has authorized the issuance of 3,500,000 shares of its Common
Stock in accordance with the terms of the Stock Option Plan. Options to purchase
300,000 shares have been granted under the Stock Option Plan and it is
anticipated that approximately 2,328,600 shares of Common Stock will be granted
upon the closing of the Offerings to certain other officers, directors and
former stockholders of the Founding Companies. The Company intends to file a
registration statement on Form S-8 under the Securities Act registering the
issuance of shares upon exercise of options granted under the Plan. As a result,
such shares will be eligible for resale in the public market.
    
 
     The Company currently intends to file a registration statement covering
6,000,000 additional shares of Common Stock under the Securities Act for its use
in connection with future acquisitions. These shares generally will be freely
tradeable after their issuance by persons not affiliated with the Company unless
the Company contractually restricts their resale.
 
   
     The Company and each of its directors and executive officers have agreed
not to (i) directly or indirectly, offer, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant for the sale of, or otherwise transfer or dispose
of any shares of Common Stock or any securities convertible into or exchangeable
or exercisable for Common Stock or file any registration statement under the
Securities Act with respect to any of the foregoing or (ii) enter into any swap
or any other agreement or any transaction that transfers, in whole or in part,
directly or indirectly, the economic consequence of ownership of the Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock whether any such swap or transaction described in clause (i) or
(ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise, for a period of 180 days from the date of this
Prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner &
Smith Incorporated on behalf of the Underwriters, except for (i) shares issued
in connection with acquisitions, provided that (except with respect to shares
issued in transactions in which the issuance or resale of such shares is not
registered under the Securities Act), the recipients of such shares agree to be
bound by similar restrictions and (ii) any shares of Common Stock issued or
options to purchase Common Stock granted pursuant to the Company's benefit plans
described herein. In addition, the current stockholders of the Company and the
owners of the Founding Companies have agreed with the Company not to sell,
contract to sell or otherwise dispose of any shares of Common Stock owned as of
the consummation of the Acquisitions, including shares received as consideration
in the Acquisitions, for a period of two years following receipt thereof,
subject to the rights of such holders to exercise their registration rights as
described below.
    
 
   
     Prior to the Offerings, there has been no established trading market for
the Common Stock, and no predictions can be made as to the effect that sales of
Common Stock under Rule 144, pursuant to a registration statement, or otherwise,
or the availability of shares of Common Stock for sale, will have on the market
price prevailing from time to time. Sales of substantial amounts of Common Stock
in the public market, or the perception that such sales could occur, could
depress the prevailing market price. Such sales may also make it more difficult
for the Company to issue or sell equity securities or equity-related securities
in the future at a time and price that it deems appropriate. See "Risk
Factors -- Shares Eligible for Future Sale."
    
 
     Former stockholders of the Founding Companies, certain executive officers
and directors are entitled to certain rights with respect to the registration of
their shares of Common Stock under the Securities Act. In the
 
                                       67
<PAGE>   73
 
   
aggregate, these groups hold 16,365,336 shares of Common Stock. If the Company
proposes to register any of its securities under the Securities Act, such
stockholders are entitled to notice of such registration and are entitled to
include, at the Company's expense, all or a portion of their shares therein,
subject to certain conditions. These registration rights will not apply to the
registration statement the Company intends to file for use in future
acquisitions or with respect to employee benefit plans.
    
 
   
       CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES TO NON-U.S. HOLDERS
    
 
   
     The following is a general summary of certain United States federal income
and estate tax consequences expected to result under current law from the
purchase, ownership and taxable disposition of Common Stock by a person or
entity other than (i) a citizen or resident of the United States, (ii) a
corporation, partnership or other entity created or organized in or under the
laws of the United States or of any state thereof, (iii) an estate, the income
of which is subject to United States federal income taxation regardless of its
source or (iv) a trust whose administration is subject to the primary
supervision of a United States court and which has one or more United States
fiduciaries who have the authority to control all substantial decisions of the
trust (a "Non-U.S. Holder"). This summary does not address all of the United
States federal income and estate tax considerations that may be relevant to a
Non-U.S. Holder in light of its particular circumstances or to Non-U.S. Holders
that may be subject to special treatment under United States federal income tax
laws (such as insurance companies, tax-exempt organizations, financial
institutions, brokers, dealers in securities, and taxpayers that are neither
citizens nor residents of the United States, or that are foreign corporations,
foreign partnerships or foreign estates or trusts as to the United States).
Furthermore, this summary does not discuss any aspect of state, local or foreign
taxation. This summary is based on current provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), Treasury regulations, judicial opinions,
published positions of the United States Internal Revenue Service (the "IRS")
and other applicable authorities, all of which are subject to change, possibly
with retroactive effect. Each prospective purchaser of Common Stock is advised
to consult its tax advisor with respect to the tax consequences of acquiring,
holding and disposing of Common Stock.
    
 
   
DIVIDENDS
    
 
   
     Dividends paid to a Non-U.S. Holder of Common Stock generally will be
subject to withholding of United States federal income tax at a 30 percent rate
(or such lower rate as may be specified by an applicable income tax treaty)
unless the dividends are effectively connected with the conduct of a trade or
business of the Non-U.S. Holder within the United States, in which case the
dividends will be taxed at ordinary United States federal income tax rates and
will not be subject to the withholding tax described above. If the Non-U.S.
Holder is a corporation, such effectively connected income may also be subject
to an additional "branch profits tax."
    
 
   
SALE OR DISPOSITION OF COMMON STOCK
    
 
   
     A Non-U.S. Holder generally will not be subject to United States federal
income tax in respect of any gain recognized on the sale or other taxable
disposition of Common Stock so long as (i) the gain is not effectively connected
with a trade or business of the Non-U.S. Holder in the United States; (ii) in
the case of a Non-U.S. Holder who is an individual and holds the Common Stock as
a capital asset, either (a) such holder is not present in the United States for
183 or more days in the taxable year of the disposition or (b) such holder does
not have a "tax home" in the United States for United States federal income tax
purposes or does not maintain an office or other fixed place of business in the
United States to which such gain is attributable; (iii) the Non-U.S. Holder is
not subject to tax pursuant to the provisions of United States federal income
tax law applicable to certain United States expatriates or (iv) the Common Stock
continues to be "regularly traded on an established securities market" for
United States federal income tax purposes and the Non-U.S. Holder has not held,
directly or indirectly, at any time during the five-year period ending on the
date of disposition (or, if shorter, the Non-U.S. Holder's holding period), more
than 5 percent of the outstanding Common Stock.
    
 
                                       68
<PAGE>   74
 
   
BACKUP WITHHOLDING AND INFORMATION REPORTING
    
 
   
     United States backup withholding tax generally will not apply to dividends
paid on Common Stock to a Non-U.S. Holder at an address outside the United
States. The Company must report annually to the IRS and to each Non-U.S. Holder
the amount of dividends paid to such holder and the amount, if any, of tax
withheld with respect to such dividends. This information may also be made
available to the tax authorities in the Non-U.S. Holder's country of residence.
    
 
   
     Upon the sale or other taxable disposition of Common Stock by a Non-U.S.
Holder to or through a United States office of a broker, the broker must backup
withhold at a rate of 31 percent and report the sale to the IRS, unless the
holder certifies its non-U.S. status under penalties of perjury or otherwise
establishes exemption. Upon the sale or other taxable disposition of Common
Stock by a Non-U.S. Holder to or through the foreign office of a United States
broker, or a foreign broker with certain types of relationships to the United
States, the broker must report the sale to the IRS (but is not required to
backup withhold) unless the broker has documentary evidence in its files that
the seller is a Non-U.S. Holder and certain other conditions are met, or the
holder otherwise establishes an exemption.
    
 
   
     Backup withholding is not an additional U.S. federal income tax. Amounts
withheld under the backup withholding rules are generally allowable as a refund
or credit against such Non-U.S. Holder's United States federal income tax
liability, if any, provided that the required information is furnished to the
IRS.
    
 
   
     The United States Treasury department has recently issued regulations
generally effective for payments made after December 31, 1998 that will affect
the procedures to be followed by a Non-U.S. Holder in establishing such holder's
status as a Non-U.S. Holder for purposes of the withholding, backup withholding
and information reporting rules discussed herein. Among other things, a Non-U.S.
Holder may be required to furnish new certification of foreign status.
Prospective investors should consult their advisors concerning the effect of
such regulations on an investment in the Common Stock.
    
 
   
FEDERAL ESTATE TAXES
    
 
   
     Common Stock owned or treated as owned by an individual who is not a
citizen or resident (as specially defined for United States federal estate tax
purposes) of the United States at the time of death will be included in such
individual's gross estate for United States federal estate tax purposes, unless
an applicable estate tax treaty provides otherwise.

Sanders Morris Mundy Inc. are acting as representatives. Subject to the terms
and conditions set forth in the International Purchase Agreement, and
concurrently with the sale of 5,600,000 shares of Common Stock to the U.S.
Underwriters pursuant to the U.S. Purchase Agreement, the Company has agreed to
sell to the International Managers, and the International Managers severally
have agreed to purchase from the Company, an aggregate of 1,400,000 shares of
Common Stock. The public offering price per share and the total underwriting
discount per share are identical under the U.S. Purchase Agreement and the
International Purchase Agreement.
    
 
   
     In the U.S. Purchase Agreement and the International Purchase Agreement,
the several U.S. Underwriters and the several International Managers,
respectively, have agreed, subject to the terms and conditions set forth
therein, to purchase all of the shares of Common Stock being sold pursuant to
each such Purchase Agreement if any of such shares being sold pursuant to each
such Purchase Agreement are purchased. Under certain circumstances, the
commitments of the non-defaulting U.S. Underwriters or the International
Managers (as the case may be) may be increased as set forth in the U.S. Purchase
Agreement and the International Purchase Agreement, respectively. The closing
with respect to the sale of shares of Common Stock to be purchased by the
International Managers and the U.S. Underwriters are conditioned upon one
another.
    
 
   
     The U.S. Underwriters and the International Managers have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for the
coordination of their activities. Under the terms of the Intersyndicate
Agreement, the Underwriters are permitted to sell shares of Common Stock to each
other for purposes of resale at the public offering price, less an amount not
greater than the selling concession. Under the terms of the Intersyndicate
Agreement, the U.S. Underwriters and any dealer to whom they sell shares of
Common Stock will not offer to sell or sell shares of Common Stock to persons
who are non-United States and non-Canadian persons, and the International
Managers and any dealer to whom they sell shares of Common Stock will not offer
to sell or sell shares of Common Stock to persons who are United States or
Canadian

persons or to persons they believe intend to resell to United States or Canadian
persons, except, in each case, for transactions pursuant to the Intersyndicate
Agreement.
    
 
   
     The U.S. Representatives have advised the Company that the U.S.
Underwriters propose initially to offer the shares of Common Stock to the public
at the initial public offering price set forth on the cover page of this
Prospectus, and to certain dealers at such price less a concession not in excess
of $     per share. The U.S. Underwriters may allow, and such dealers may
reallow, a discount not in excess of $     per share to certain other dealers.
After the Offerings, the initial public offering price, concession and discount
may be changed.
    
 
   
     The Company has granted the U.S. Underwriters an option, exercisable for 30
days after the date of this Prospectus, to purchase up to an aggregate of
840,000 additional shares of Common Stock at the initial public offering price
set forth on the cover page hereof, less the underwriting discount. The U.S.
Underwriters may exercise this option to cover overallotments, if any, made on
the sale of the shares of Common Stock offered hereby. If the U.S. Underwriters
exercise this option, each U.S. Underwriter will have a firm commitment, subject
to certain conditions, to purchase approximately the same percentage thereof
which the number of shares of Common Stock to be purchased by it shown in the
foregoing table bears to the 5,600,000 shares of Common Stock initially offered
hereby. The Company has also granted an option to the International Managers,
which expires 30 days after the date of this Prospectus, to purchase up to
210,000 additional shares of Common Stock to cover over-allotments, if any, on
terms similar to those granted to the U.S. Underwriters.
    
 
   
     The Company and each of its directors and executive officers have agreed
not to (i) directly or indirectly, offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant for the sale of, or otherwise transfer or
dispose of any shares of Common Stock or any securities convertible into or
exchangeable or exercisable for Common Stock or file any registration statement
under the Securities Act with respect to any of the foregoing or (ii) enter into
any swap or any other agreement or any transaction that transfers, in whole or
in part, directly or indirectly, the economic consequence of ownership of the
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock whether any such swap or transaction described in clause (i) or
(ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise, for a period of 180 days from the date of this
Prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner &
Smith Incorporated on behalf of the Underwriters, except for (i) shares issued
in connection with acquisitions, provided that (except with respect to shares
issued in transactions in which the issuance or resale of such shares is not
registered under the Securities Act), the recipients of such shares agree to be
bound by similar restrictions and (ii) any shares of Common Stock issued or
options to purchase Common Stock granted pursuant to the Company's benefit plans
described herein.
    
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments the Underwriters may be required to make in respect thereof.
 
   
     Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase the Common Stock. As an exception to these
rules, the U.S. Underwriters are 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 pegging, fixing or maintaining the price of the
Common Stock.
    
 
   
     If the Underwriters create a short position in the Common Stock in
connection with the Offering, (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the U.S. Underwriters
may reduce that short position by purchasing Common Stock in the open market.
The U.S. Underwriters may also elect to reduce any short position by exercising
all or part of the over-allotment option described above.
    
 
   
     The U.S. Underwriters may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the U.S. Underwriters purchase
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
    
 
                                       71
<PAGE>   77
 
   
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of the Offerings.
    
 
     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 affect on the price of a security to the extent that it were
to discourage 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 U.S.
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
    
 
     The Company intends to make application to list the Common Stock on the
NYSE under the symbol "IEE."
 
   
     The U.S. Underwriters have reserved for sale, at the initial public
offering price, up to 700,000 shares of Common Stock for certain employees,
directors and business associates of, and certain other persons designated by,
the Company who have expressed an interest in purchasing such shares of Common
Stock. The number of shares available for sale to the general public in the
Offerings will be reduced to the extent such persons purchase such reserved
shares. Any reserved shares not so purchased will be offered to the general
public on the same basis as other shares offered hereby.
    
 
   
     Prior to the Offerings, there has been no established trading market for
the shares of Common Stock. The initial public offering price for the Common
Stock offered hereby has been determined by negotiations between the Company and
the Underwriters. Among the factors considered in making such determination were
the history of and the prospects for the industry in which the Company competes,
an assessment of the Company's management, the past and present operations of
the Founding Companies and the Company, the historical results of operations of
the Founding Companies and the Company and the trend of its revenues and
earnings, the prospects for future earnings of the Company, the general
condition of prices of similar securities of generally comparable companies and
other relevant factors. 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 the Offerings at or above the initial public
offering price.
    
 
     The Underwriters have informed the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
                                 LEGAL MATTERS
 
   
     Certain legal matters in connection with the Common Stock being offered
hereby will be passed upon for the Company by Andrews & Kurth L.L.P., Houston,
Texas and for the Underwriters by Vinson & Elkins L.L.P., Houston, Texas.
Partners in the firm of Andrews & Kurth L.L.P. own shares of Common Stock not
exceeding 1% of the shares of Common Stock to be outstanding upon the
consummation of the Offerings.

          INTEGRATED ELECTRICAL SERVICES, INC. AND FOUNDING COMPANIES
 
               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                             BASIS OF PRESENTATION
 
   
     The following unaudited pro forma combined financial statements give effect
to (i) the acquisitions by Integrated Electrical Services, Inc. (IES), of the
outstanding capital stock and other equity interests of Ace, Amber,
Bexar-Calhoun, Daniel, Hatfield, Haymaker, Houston-Stafford, Mills, Muth,
Pollock, Reynolds, Rodgers, Summit, Popp and Thurman & O'Connell (together, the
Founding Companies), and related transactions, and (ii) IES's initial public
offerings (the Offerings). The acquisitions (the Acquisitions) will occur
simultaneously with the closing of the Offerings and will be accounted for using
the purchase method of accounting. Houston-Stafford has been identified as the
accounting acquirer for financial statement presentation purposes.
    
 
   
     The unaudited pro forma combined balance sheet gives effect to the
Acquisitions and related transactions, and the Offering, as if they had occurred
on September 30, 1997. The unaudited pro forma combined statements of operations
give effect to these transactions as if they had occurred on October 1, 1996.
    
 
     IES has preliminarily analyzed the savings that it expects to be realized
from reductions in salaries, bonuses and certain benefits to the owners. To the
extent the owners of the Founding Companies have contractually agreed to
prospective reductions in salary, bonuses, benefits and lease payments, these
reductions have been reflected in the unaudited pro forma combined statements of
operations. With respect to other potential cost savings, IES has not and cannot
quantify these savings until completion of the Acquisitions. It is anticipated
that these savings will be offset by costs related to IES's new corporate
management and by the costs associated with being a public company. However,
because these costs cannot be accurately quantified at this time, they have not
been included in the pro forma financial information of IES.
 
   
     The pro forma adjustments are based on preliminary estimates, available
information and certain assumptions that Company management deems appropriate
and may be revised as additional information becomes available. The pro forma
financial data do not purport to represent what IES's financial position or
results of operations would actually have been if such transactions in fact had
occurred on those dates and are not necessarily representative of IES's
financial position or results of operations for any future period. Since the
Founding Companies were not under common control or management, historical
combined results may not be comparable to, or indicative of, future performance.
The unaudited pro forma combined financial statements should be read in
conjunction with the other financial statements and notes thereto included
elsewhere in this Prospectus. See also "Risk Factors" included elsewhere herein.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1. GENERAL:
 
   
     Integrated Electrical Services, Inc. (IES), was founded to create a leading
national provider of electrical contracting and maintenance services to the
commercial, industrial and residential markets. IES has conducted no operations
to date and will acquire the Founding Companies concurrently with and as a
condition of the closing of the Offerings.
    
 
   
     The historical financial statements reflect the financial position and
results of operations of the Founding Companies and were derived from the
respective Founding Companies' financial statements where indicated. The periods
included in these financial statements for the individual Founding Companies are
as of and for the year ended September 30, 1997, except for Ace, Hatfield,
Reynolds, and Popp for which the period is as of and for the year ended June 30,
1997. The audited historical financial statements included elsewhere herein have
been included in accordance with Securities and Exchange Commission (SEC) Staff
Accounting Bulletin No. 80.
    
 
2. ACQUISITION OF FOUNDING COMPANIES:
 
   
     Concurrently with and as a condition to the closing of the Offerings, IES
will acquire all of the outstanding capital stock and other equity interests of
the Founding Companies. The acquisitions will be accounted for using the
purchase method of accounting with Houston-Stafford being treated as the
accounting acquirer.
    
 
   
     The following table sets forth the consideration to be paid (a) in cash and
(b) in shares of Common Stock to the common stockholders of each of the Founding
Companies, other than the accounting acquirer (Houston-Stafford). For purposes
of computing the estimated purchase price for accounting purposes, the value of
the shares was determined using an estimated fair value of $10.50 per share (or
$94.1 million), which is less than the estimated initial public offering price
of $14.00 per share due to restrictions on the sale and transferability of the
shares issued. The total estimated purchase price of $135.9 million for the
acquisitions is based upon preliminary estimates and is subject to certain
purchase price adjustments at and following closing. The table does not reflect
net transfers of $29.8 million which represents previously undistributed 
earnings and nonoperating assets and liabilities that will be transferred in 
connection with the Acquisitions to the owners of the Founding Companies.

     (a) Reflects the $6.1 million reduction in salaries, bonuses and benefits
         to the owners of the Founding Companies. These reductions in salaries,
         bonuses and benefits have been agreed prospectively in accordance with
         the terms of the employment agreements. Such employment agreements are
         primarily for five years, contain restrictions related to competition
         and provide severance for termination of employment in certain
         circumstances.
    
 
     (b) Reflects the amortization of goodwill to be recorded as a result of
         these Acquisitions over a 40-year estimated life, as well as a
         reduction in historical Founding Companies' minority interest expense
         attributable to minority interests that will be acquired as part of the
         transaction.
 
   
     (c) Reflects the reversal of the non-recurring compensation charge of $38.1
         million recorded by IES for shares issued to management for nominal
         consideration. Also, reflects interest expense of $1.4 million on
         borrowings of $18.2 million necessary to fund the transfers discussed
         in 3(a) above, net of interest savings of $.8 million on the $8.1
         million of debt to be repaid using proceeds from the Offering or to be
         transferred to the Founding Companies as discussed in 3(a) above.
    
 
     (d) Reflects the incremental provision for federal and state income taxes
         at a 38% overall tax rate before goodwill and other permanent items,
         relating to the other statements of operations adjustments and for
         income taxes on S Corporation income not provided for in the historical
         financial statements.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
   
To Houston-Stafford Electric, Inc.:
    
 
   
     We have audited the accompanying consolidated balance sheets of
Houston-Stafford Electric, Inc., a Texas corporation, and consolidated entity as
of December 31, 1995 and 1996 and September 30, 1997, and the related
consolidated statements of operations, cash flows and stockholder's equity for
each of the three years in the period ended December 31, 1996 and for the year
ended September 30, 1997. 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 Houston-Stafford Electric,
Inc. and consolidated entity as of December 31, 1995 and 1996 and September 30,
1997, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996 and for the year ended
September 30, 1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
    
 
1. BUSINESS AND ORGANIZATION AND BASIS OF PRESENTATION:
 
     Houston-Stafford Electric, Inc. (the Company), a Texas corporation, focuses
on providing electrical system installation and repair services primarily for
residential and mid-sized to large commercial facilities. Work on new structures
is performed primarily under fixed-price contracts. The Company performs the
majority of its contract work under fixed-price contracts with contract terms
ranging from six to 18 months. The Company performs the majority of its work in
Texas and has operations in other states.
 
   
In April 1997, the Company acquired an electrical supply company from a  third
party for $100,000. The purchase of such electrical supply company has been
reflected as a purchase business combination. Consequently, the accompanying
financial statements reflect the consolidated results of operations and
financial position of the Company and the acquired electrical supply company
for periods subsequent to April 1997. All significant intercompany transactions
and balances have been eliminated for those periods.
    
 
   
     In October 1997, the Company and its stockholder entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

</TABLE>
    
 
  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are valued by the Company at the lower of cost or market
using the first-in, first-out (FIFO) method.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation expense was
approximately $55,000, $76,000 and $133,000 for the years ended December 31,
1994, 1995 and 1996 and $187,000 for the year ended September 30, 1997,
respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools,
repairs and depreciation costs. Provisions for total estimated losses on
uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income. The
effects of these revisions are recognized in the period in which the revisions
are determined. An amount equal to contract costs attributable to claims is
included in revenues when realization is probable and the amount can be reliably
estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's
 
                                      F-16

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
experience with similar contracts in recent years, the retention balance at each
balance sheet date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs.
 
  Accounts Receivable and Provision for Doubtful Accounts
 
   
     Accounts receivable at December 31, 1995, 1996 and September 30, 1997,
include approved claims and change orders which were expected to be collected
within the fiscal year.
    
 
     The Company provides an allowance for doubtful accounts based on a
specified percentage of outstanding receivables and the specific identification
of accounts receivable where collection is no longer probable.
 
  Income Taxes
 
     The Company follows the asset and liability method of accounting for income
taxes in accordance with Statement of Financial Accounting Standards (SFAS) No.
109. Under this method, deferred assets and liabilities are recorded for future
tax consequences of temporary differences between the financial reporting and
tax bases of assets and liabilities, and are measured using enacted tax rates
and laws.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 11 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of
recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

assumption of a note due HSC Building Co., Inc., of $25,376.
    
 
   
     At September 30, 1997, the company did not have a balance due to or from

     In May 1996, the Company acquired a building and land at a cost of
$220,115. The financing for the acquisition was provided by an officer of the
Company, Ben Mueller. An installment promissory note of $208,123 was signed by

     In August 1996, the Company negotiated the purchase of the stock of Ben
Mueller, a principal who had a one-third interest. The selling price of the
shares totaled $800,000. The Company has signed an installment promissory note
which will provide for the payout of $800,000 over seven years at 8 percent
interest and is secured by the purchased stock.
    
 
   
     Certain costs incurred by the Company are allocated to other affiliated
companies on the basis of gross payroll dollars.
    
 
   
     As a result of the acquisition of the electrical supply company, the
Company assumed two non-compete agreements with certain related parties. The

     The Company has a defined contribution benefit plan. The Company may make
discretionary contributions. Through September 30, 1997, the Company has made no
contributions to the plan.
    
 
10. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, receivables from related parties, other receivables,
accounts payable, a line of credit, notes payable and long-term debt. The
Company believes that the carrying value of these instruments on the
accompanying balance sheets approximates their fair value.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company also
carries employment practices liability coverage. The Company has not incurred
significant uninsured losses on any of these items.
 
     Additionally, the Company provides workers' compensation coverage. The
policy has no deductible and provides coverage in the amount of $500,000 per
accident.
 
   
     During 1997, a general contractor with which the Company does business
acquired a line of credit from a bank on which the Company agreed to act as 2nd
guarantor. This guaranty expires in December of 1997 and is in the amount of
$750,000.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company had sales of approximately 15 percent, 11 percent and 10
percent of total sales to one major customer during the years ended December 31,
1995, 1996 and September 30, 1997, respectively.
    
 
     In addition, the Company grants credit, generally without collateral, to
its customers, which are general contractors and home builders, located
primarily in Texas. Consequently, the Company is subject to potential credit
risk related to changes in business and economic factors within the Texas
construction and home-building market. However, management believes that its
contract acceptance, billing and collection policies are adequate to minimize
any potential credit risk.
 
   
     The Company routinely maintains cash balances in financial institutions in
    
   
excess of federally insured limits.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
   
     Integrated Electrical Services, Inc., a Delaware corporation (IES or the
Company), was founded in June 1997 to create a leading national provider of
electrical contracting and maintenance services, focusing primarily on the
residential, commercial and industrial markets. IES intends to acquire certain
U.S. businesses (the Acquisitions), complete the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of its common stock and, subsequent to the Offerings,
continue to acquire through merger or purchase similar companies to expand its
national and regional operations.
    
 
   
     IES has not conducted any operations, and all activities to date have
related to the Offerings and the Acquisitions. All expenditures of the Company
to date have been funded by its current primary stockholder, on behalf of the
Company. The Company's primary stockholder has also committed to fund future
organization expenses and offering costs. As of September 30, 1997, costs of
approximately $1,560,000 have been incurred in connection with the Offerings,
and such costs will be treated as a reduction of the proceeds from the
Offerings. IES has treated these costs as deferred offering costs in the
accompanying balance sheet. IES is dependent upon the Offerings to execute the
pending Acquisitions and to repay its current primary stockholder for funding
deferred offering costs. There is no assurance that the pending Acquisitions
will be completed. The ability of IES to generate future operating revenues is
dependent upon the ability of the Company to manage the effect on the combined
companies of changes in demand for commercial and residential construction, the
effect of business growth, including the availability of electricians, and the
need for other key personnel. These risk factors are discussed in more detail in
"Risk Factors".
    
 
2. STOCKHOLDERS' EQUITY:
 
  Common Stock and Preferred Stock
 
   
     In connection with the organization and initial capitalization of IES, the
Company issued 2,329,569 shares (as restated for the 2,329.6-for-one stock split
discussed below) of common stock at $.01 par value (Common Stock). IES
subsequently issued another 1,722,742 shares (as restated for the
2,329.6-for-one stock split discussed below) of Common Stock at $.01 par value
to certain management of IES. Consequently, as restated for the 2,329.6-for-one
stock split discussed below, the Company had issued a total of 2,655,709 shares
to its founder and an aggregate of 1,396,602 shares to other executive
management of the Company. As a result of the issuance of shares to management
for nominal consideration, the Company recorded for financial statement
presentation purposes, a nonrecurring, noncash compensation charge of $38.1
million, which is calculated based on a fair value which is discounted from the
estimated initial public offering price.
    
 
   
     IES effected a 2,329.6-for-one stock split in October 1997, for each share
of common stock of the Company then outstanding. In addition, the Company
increased the number of authorized shares of Common Stock to 100,000,000 and
increased the number of authorized shares of $.01 par value preferred stock to
10,000,000. The effects of the Common Stock split and the increase in the shares
of authorized Common Stock have been retroactively reflected on the balance
sheet, statement of stockholders' equity and in the accompanying notes.
Additionally, the difference between the initial capitalization and the par
value of Common Stock outstanding subsequent to the stock split has been
reflected as a receivable from stockholders, which is presented as a reduction
in stockholders' equity in the accompanying financial statements .
    
 
   
  Restricted Common Stock
    
 
   
     In October 1997, the 2,655,709 shares of Common Stock held by the founder
of IES were converted into 2,655,709 shares of restricted common stock. The
shares of restricted common stock have rights similar to shares of Common Stock,
except that such shares are entitled to elect one member of the board of
directors and are entitled to one-half of one vote for each share held on all
other matters. Each share of restricted

common stock will convert into Common Stock (i) upon disposition by the holder
of such shares, or (ii) in the event that any person acquires, or offers to
acquire, 15% or more of the total outstanding shares of Common Stock.
    
 
  Stock Plan
 
   
     In September 1997, the Company's board of directors and stockholders
approved the Company's 1997 Stock Plan (the Plan), which provides for the
granting or awarding of incentive or nonqualified stock options, stock
appreciation rights, restricted or phantom stock, and other incentive awards to
directors, officers, key employees and consultants of the Company. The number of
shares authorized and reserved for issuance under the Plan is the greater of 3.5
million shares or 15% of the aggregate number of shares of Common Stock
outstanding. The terms of the option awards will be established by the
Compensation Committee of the Company's board of directors. The Company intends
to file a registration statement on Form S-8 under the Securities Act
registering the issuance of shares upon exercise of options granted under this
Plan. The Company expects to grant nonqualified stock options to purchase a
total of approximately 2.3 million shares of Common Stock to key employees of
the Company at the initial public offering price upon consummation of the
Offerings. These options will vest at the rate of 20 percent per year,
commencing on the first anniversary of the grant date and will expire ten years
from the date of grant, three months following termination of employment due to
death or disability, or one year following termination of employment by means
other than death or disability. In September 1997, 300,000 options were granted
to certain key employees under the Plan with an exercise price equal to 60% of
the initial public offering price. These options vest at a rate of 20 percent
per year, commencing on the date of grant. The compensation expense recognized
for these options prior to September 30, 1997 was not material as they were not
granted until September 1997.
    
 
  Directors' Stock Plan
 
   
     In September 1997, the Company's board of directors and stockholders
approved the 1997 Directors' Stock Plan (the Directors' Plan), which provides
for the granting or awarding of stock options to nonemployees. The number of
shares authorized and reserved for issuance under the Directors' Plan is 250,000
shares. The Directors' Plan provides for the automatic grant of options to
purchase 5,000 shares to each nonemployee director serving in such capacity at
the commencement of the Offering.
    
 
     Each nonemployee director will be granted options to purchase an additional
5,000 shares at the time of an initial election of such director. In addition,
each director will be automatically granted options to purchase 5,000 shares
annually at each September 30 on which such director remains a director. All
options will have an exercise price based on the fair market value at the date
of grant and have vesting terms similar to options granted under the Stock Plan
discussed above.
 
     The Directors' Plan allows nonemployee directors to receive additional
option grants in amounts and at terms as deemed appropriate by the Company's
board of directors.
 
3. STOCK-BASED COMPENSATION:
 
     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," allows entities to choose between a new fair value
method of accounting for employee stock options or similar equity instruments
and the current method of accounting prescribed by Accounting Principles Board
(APB) Opinion No. 25 under which compensation expense is recorded to the extent
that the fair market value of the related stock is in excess of the options
exercise price at date of grant. Entities electing to remain with the accounting
in APB Opinion No. 25 must make pro forma disclosures of net income and earnings
per share as if the fair value method of accounting prescribed in SFAS No. 123
had been applied. The Company will measure compensation expense attributable to
stock options based on the method prescribed in APB Opinion

No. 25 and will provide the required pro forma disclosure of net income and
earnings per share, as applicable, in the notes to future consolidated annual
financial statements.
 
   
4. NEW ACCOUNTING PRONOUNCEMENTS:
    
 
   
     SFAS No. 128 requires the presentation of basic earnings per share and
diluted earnings per share in financial statements of public enterprises rather
than primary and fully diluted earnings per share as previously required. Under
the provisions of this statement, basic earnings per share will be computed
based on weighted average shares outstanding and will exclude dilutive
securities such as options, warrants, etc. Diluted earnings per share will be
computed including the impacts of all potentially dilutive securities. The
Company will adopt this statement in December 1997, but does not anticipate that
the statement will have a material impact on the Company.
    
 
   
     SFAS No. 129 will require additional disclosure of information about an
entity's capital structure, including information about dividend and liquidation
preferences, voting rights, contracts to issue additional share, conversion and
exercise prices, etc. The Company will adopt this statement in December 1997.
    
 
   
     SFAS No. 130 requires the presentation of comprehensive income in an
entity's financial statements. Comprehensive income represents all changes in
equity of an entity during the reporting period, including net income and
charges directly to equity which are excluded from net income. This statement is
not anticipated to have a material impact on the Company, or its financial
disclosures, as the Company currently does not plan to enter into any material
transactions which result in charges (or credits) directly to equity (such
additional minimum pension liability changes, currency translation adjustments,
unrealized gains and losses on available for sale securities, etc.).
    
 
   
5. FOUNDING COMPANY ACQUISITIONS:
    
 
   
     IES has signed definitive agreements to acquire the following entities (the
Founding Companies) to be effective contemporaneously with the Offerings. The
entities to be acquired are:
    
 
         Ace Electric, Inc.
         Amber Electric, Inc.
         BW Consolidated, Inc. and Subsidiaries
         Daniel Electrical Contractors, Inc. and Daniel Electrical of Treasure
         Coast, Inc.
         Hatfield Electric, Inc.
   
         Charles P. Bagby Company, Inc. and General Partner, Inc.
    
         Houston-Stafford Electric, Inc. and Stark Investments, Inc.
         Mills Electrical Contractors, Inc. and Subsidiaries
         Muth Electric, Inc.
         Pollock Electric, Inc.
         Reynolds Electric Corp.
         Rodgers Electric Co., Inc.
         Summit Electric of Texas, Inc.
         Thomas Popp & Co., Inc.
         Thurman & O'Connell Corp.
 
     The aggregate consideration that will be paid by IES to acquire the
Founding Companies is approximately $57.5 million in cash and 12.3 million
shares of Common Stock.
 
     In addition, the Company has entered into employment agreements with
certain key executives of the Founding Companies and the executive officers of
IES. These employment agreements generally prohibit such individuals from
disclosing confidential information and trade secrets, and restrict such
individuals from

competing with the Company for a period of two years following termination of
employment. The initial term of these employment agreements is five years with
provisions for annual extensions at the end of the initial term.
 
   
6. EVENTS SUBSEQUENT TO THE DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC
   ACCOUNTANTS (UNAUDITED)
    
 
   
     The Company expects to enter into a credit facility effective concurrently
with the closing of the Offerings. A commercial bank has agreed to structure the
credit facility subject to the terms and conditions of a commitment letter.
According to these terms, the credit facility will be a three-year revolving
credit facility of up to $65 million to be used for working capital, capital
expenditures, to finance acquisitions and for other general corporate purposes.
The Company's existing and future subsidiaries will guarantee the repayment of
all amounts due under the facility and the facility will be secured by the
capital stock of those subsidiaries and the accounts receivable of the Company
and those subsidiaries. The Company expects that the credit facility will
require the consent of the lenders for acquisitions exceeding a certain level of
cash consideration, prohibit the payment of cash dividends by the Company,
restrict the ability of the Company to incur other indebtedness and require the
    
   
Company to comply with certain financial covenants.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Mills Electrical Contractors, Inc. and Subsidiary:
 
   
     We have audited the accompanying consolidated balance sheets of Mills
Electrical Contractors, Inc., a Texas corporation, and Subsidiary as of December
31, 1995 and 1996 and September 30, 1997, and the related consolidated
statements of operations, cash flows and stockholders' equity for each of the
three years in the period ended December 31, 1996 and for the year ended
September 30, 1997. 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 Mills Electrical
Contractors, Inc. and Subsidiary as of December 31, 1995 and 1996 and September
30, 1997, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1996 and for the year ended
September 30, 1997, in conformity with generally accepted accounting principles.

               MILLS ELECTRICAL CONTRACTORS, INC. AND SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
   
     The accompanying consolidated financial statements include the accounts of
Mills Electrical Contractors, Inc. (Mills), a Texas corporation, and its 89%
owned subsidiary, Fort Worth Regional Electrical Systems, L.L.C. (RES), a Texas
limited liability company (collectively, the Company). The subsidiary was formed
during 1996. In September 1997, Mills sold 10% of the capital stock of RES to an
officer of RES at net book value per share resulting in proceeds to the Company
of $71,000. Financial statements prior to 1996 reflect only the accounts of
Mills, Inc. All significant intercompany transactions have been eliminated in
consolidation.
    
 
     The Company focuses on providing electrical system installation and repair
services primarily for mid-sized to large commercial facilities as well as
residential facilities. The Company performs the majority of its contract work
under fixed price contracts, with contract terms generally ranging from 12 to 36
months. The Company performs the majority of its work in the Dallas-Fort Worth,
Texas, area.
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offering) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Supplemental Cash Flow Information (in thousands)
 
   
     The Company had the following noncash investing and financing activities
for the years ended December 31, 1994, 1995, 1996 and September 1997:

     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation and
amortization expense was $179,000, $253,000 and $385,000 and 637,000 for the
years ended December 31, 1994, 1995 and 1996 and September 30, 1997,
respectively.
    
 
     In June 1996, RES agreed to purchase a business, consisting of equipment in
a capital lease transaction and an agreement to lease a building under an
operating lease, as well as purchased the rights to the name "Regional Electric
Systems" from an individual who became an officer of RES. The acquired assets
were recorded at their estimated fair market value using the purchase method of
accounting. The transaction resulted in the recognition of goodwill of
approximately $185,000 which is being amortized over a 20 year period.
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools
and repairs. Provisions for the total estimated losses on uncompleted contracts
are made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs.

  Accounts Receivable and Provision for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable and a general reserve based upon the total trade and retainage accounts
receivable balances.
 
  Income Taxes
 
     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their share of the
Company's taxable earnings or losses in their personal tax returns.
Consequently, the accompanying financial statements of the Company include only
a provision for state income taxes and do not include a provision for current or
deferred federal income taxes. The Company intends to terminate its S
Corporation status concurrently with the effective date of the Offering.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 11 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
   
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairment would be to expense the difference between the fair value of such
property and its carrying value. Adoption of this standard did not have a
material effect on the consolidated financial position or results of operations
of the Company.

     Additionally, the Company has guaranteed an officer note at a bank with an
outstanding balance of approximately $298,000 at December 31, 1996. The
Company's property and equipment has been cross-pledged as collateral.
 
8. EMPLOYEE BENEFIT PLAN:
 
   
     The Company has a defined contribution profit-sharing plan that covers all
employees meeting certain age and service requirements. Company contributions to
the plan are at the discretion of the board of directors. Contributions to the
plan charged to operations in 1994, 1995, 1996 and the year ended September 30,
1997 were $186,000, $450,000, $789,000 and $789,000, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
9. FINANCIAL INSTRUMENTS:
 
   
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, accounts payable, a line of credit, notes payable and
long-term debt. The Company believes that the carrying values of these
instruments on the accompanying consolidated balance sheets approximates their
fair values.
    
 
10. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
   
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's consolidated
financial position or results of operations.
    
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including workers'
compensation, business auto liability, commercial general liability, property
and an umbrella policy. The Company has not incurred significant uninsured
losses on any of these items.
 
11. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company had sales greater than 10 percent of total sales to three major
customers (comprising approximately 20%, 12% and 11% of total sales), two major
customers (comprising approximately 15% and 13% of total sales), two major
customers (comprising approximately 20% and 18% of total sales) and one major
customer (comprising approximately 32% of total sales during the years ended
December 31, 1994, 1995, 1996 and September 1997, respectively.
    
 
     In addition, the Company grants credit, generally without collateral, to
its customers, which are usually general contractors located primarily in the
Dallas-Fort Worth, Texas area. Consequently, the Company is subject to potential
credit risk related to changes in business and economic factors within the
Dallas-Fort Worth, Texas, area. However, management believes that its contract
acceptance, billing and collection policies are adequate to minimize the
potential credit risk.
 
  Cash and Cash Equivalents
 
     The Company routinely maintains cash balances in financial institutions in
excess of federally insured limits.
 
12. BACKCHARGE CLAIMS:
 
   
     It is the Company's policy to recognize income from backcharge claims only
when a definitive agreement has been reached and collection is reasonably
assured. In December 1996, the Company reached a settlement on one of its
backcharge claims related to prior periods for approximately $856,000 which is
reflected in the accompanying consolidated statement of operations for the year
ended December 31, 1996, as an increase in revenues and as a component of other
receivables in the accompanying consolidated balance sheet at December 31, 1996.
This amount was collected in 1997.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To BW Consolidated, Inc. and Subsidiaries:
 
   
     We have audited the accompanying consolidated balance sheets of BW
Consolidated, Inc., a Texas corporation, and Subsidiaries as of December 31,
1995 and 1996 and September 30, 1997, and the related consolidated statements of
operations, cash flows and stockholders' equity for each of the three years in
the period ended December 31, 1996 and for the year ended September 30, 1997.
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 BW Consolidated, Inc. and
Subsidiaries as of December 31, 1995 and 1996 and September 30, 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1996 and for the year ended September 30, 1997, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS, ORGANIZATION AND BASIS OF PRESENTATION:
 
     BW Consolidated, Inc. (the Company), a Nevada S Corporation, and
Subsidiaries, two of which are Texas limited partnerships, focuses on providing
electrical system installation and repair services primarily for residential and
mid-sized to large commercial facilities. The Company performs the majority of
its contract work under fixed price contracts with contract terms generally
ranging from three to 24 months. The Company performs the majority of its work
in Texas.
 
     In January 1996, the original parent company, Bexar Enterprises, Inc., a
Nevada C Corporation, was merged with BW Investments, Inc., Bexar Electric
Company, Inc., and Calhoun Electric Company, Inc., all wholly owned
subsidiaries. The survivor of the merger was Calhoun Electric Company, Inc., a
Texas S Corporation, and its 90 percent owned subsidiary, Bexar Electric
Company, Ltd. (BEC), a Texas limited partnership. The 10 percent minority
interest in the partnership was purchased by employees of Bexar Electric
Company, Ltd. An additional 10 percent minority interest in Bexar Electric
Company, Ltd. (a Texas limited partnership), was purchased by employees of the
Company in January 1997.
 
     In May 1997, Calhoun Electric Company, Inc., a Texas S Corporation,
transferred its assets and liabilities to Calhoun Electric Company, Ltd. (CEC),
a Texas limited partnership. Subsequent to this transfer, Calhoun Electric
Company, Inc., a Texas S Corporation, reorganized as a Nevada S Corporation and
changed its name to BW Consolidated, Inc.
 
     The accompanying financial statements present BW Consolidated, Inc. (and
its predecessors), together with its majority-owned subsidiaries on a
consolidated basis. All significant intercompany activity has been eliminated in
consolidation. Additionally, minority interests in subsidiaries of BW
Consolidated, Inc. have been reflected as "Minority Interest" in the
accompanying consolidated financial statements.
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment. Additionally, in October 1997, the majority shareholder of the
Company transferred 15 percent of its interest in CEC to a former shareholder of
Calhoun Electric Company, Inc. and current employer of CEC.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid debt instruments with an original
maturity of three months or less when purchased to be cash equivalents.

  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
average cost method.
 
  Property and Equipment
 
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the consolidated statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools,
repairs and depreciation costs. Provisions for the total estimated losses on
uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income and
their effects are recognized in the period in which the revisions are
determined. An amount equal to contract costs attributable to claims is included
in revenues when realization is probable and the amount can be reliably
estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts,"' represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     The Company warrants labor for the first year after installation of new
electrical systems and servicing of existing electrical systems. A reserve for
warranty costs is recorded based upon the historical level of warranty claims
and management's estimate of future costs.
 
  Provision for Doubtful Accounts
 
   
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
    
 
  Income Taxes
 
   
     The Company has elected S Corporation status effective January 1, 1996, as
defined by the Internal Revenue Code, whereby the Company itself is not subject
to taxation for federal purposes. Under S Corporation status, the stockholders
report their share of the Company's taxable earnings or losses in their personal
tax returns. Consequently, the accompanying financial statements of the Company
do not include a provision for current or deferred income taxes (see Note 7).
The Company intends to terminate its S Corporation status concurrently with the
effective date of the Offering (see Note 1).
    
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 10 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncements
 
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairment would be to expense the difference between the fair value of such
property and its carrying value. Adoption of this standard did not have a
material effect on the financial position or results of operations of the
Company.

     The Company currently has two lines of credit established. The first line
of credit for $750,000, secured by BEC accounts receivable, inventory and
equipment, requires monthly payments of interest at 1 percent over the prime
rate. At December 31, 1995 and 1996 and at September 30, 1997, respectively,
there were no advances outstanding against the line and the full $750,000 was
available. The note maturity date is April 1998. The second line of credit for
$500,000, secured by CEC accounts receivable, inventory, equipment and trucks,
requires monthly payments of interest at 1/2 percent over the prime rate. During
the 1997, this line of credit agreement was renewed and was increased from
$300,000 to $500,000. At December 31, 1995 and 1996, respectively, there were no
advances outstanding against the line and the full $300,000 was available. At
September 30, 1997, there was no advance outstanding against the line and the
full $500,000 was available. The note maturity date is May 1998.

     Deferred income tax provisions result from temporary differences in the
recognition of income and expenses for financial reporting purposes and for tax
purposes. The tax effects of these temporary differences, representing deferred
tax assets and liabilities, result principally from the following:

     Effective January 1, 1996, the Company elected S Corporation status for
Calhoun Electric and partnership status for Bexar Electric. The Company will no
longer be directly responsible for any deferred tax liability which might exist.
The removal of the deferred tax liability which existed as of December 31, 1995,
is recognized in the 1996 consolidated statement of operations (see Note 2).

     The Company recognized interest income from a stockholder of $--, $30,000,
$13,000 and $5,000 in 1994, 1995, 1996 and for the year ended September 30,
1997, respectively.
    
 
9. EQUITY:
 
     In 1991, the Company adopted an employee stock ownership plan (ESOP) for
the benefit of the Company's employees. The plan covered substantially all
employees of the Company. The Company's contributions to the plan are at the
discretion of the board of directors, but may not exceed the maximum allowable
deduction permitted under the Internal Revenue Code at the time of the
contribution. Under this ESOP plan, employees cannot make contributions to the
plan. The Company made a contribution of $35,000 and $25,000 in 1994 and 1995,
respectively. Effective December 8, 1995, the Company has requested and received
approval from the Internal Revenue Service to terminate the ESOP plan. In
accordance with the termination of the ESOP, the Company repurchased as treasury
stock 5,088 shares for $961,000.
 
   
     In 1996, the Company sold a minority interest in the limited partnership of
Bexar Electric to certain employees of the Company. The minority interest is
considered a limited partner; the minority interest held 10 percent and 20
percent at December 31, 1996 and September 30, 1997, respectively.
    
 
10. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, notes receivable from stockholders, accounts payable, a
line of credit, notes payable and long-term debt. The Company believes that the
carrying value of these instruments on the accompanying balance sheets
approximates their fair value.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant uninsured losses on any of these items.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
     The Company had sales of approximately 11 percent of total sales to one
major customer during the year ended December 31, 1996.
 
   
     The Company had accounts receivable balances of approximately 15 percent
and 14 percent of total accounts receivable from two major customers as of
December 31, 1996, and approximately 10% due from one major customer for the
year ended September 30, 1997.
    
 
   
     The Company had cash and cash equivalents in financial institutions which
exceeded the federally insured limits by $911,000, $269,000 and $858,000 at
December 31, 1995 and 1996, and September 30, 1997, respectively.
    
 
   
     In addition, the Company grants credit, generally without collateral, to
its customers, which are primarily general contractors, located in Central and
South Texas. Consequently, the Company is subject to potential credit risk
related to changes in business and economic factors within the state of Texas.
However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.

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 Muth Electric, Inc., as of
December 31, 1995 and 1996 and September 30, 1997, and the results of its

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
     Muth Electric, Inc. (the Company), a South Dakota corporation, focuses on
providing electrical system installation and repair services primarily for
residential and commercial facilities. The Company performs the majority of its
contract work under fixed-price contracts with contract terms generally ranging
from one to 12 months. The Company performs the majority of its work in South
Dakota and surrounding states.
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offering) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the estimated useful
life of the asset. Depreciation expense was approximately $142,000, $185,000,
$224,000 and $212,000 for the years ended December 31, 1994, 1995, 1996 and
September 30, 1997, respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-
 
                                      F-66

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
completion method measured by the percentage of costs incurred to date to total
estimated costs for each contract. Contract costs include all direct material
and labor costs and those indirect costs related to contract performance, such
as indirect labor and depreciation costs. Provisions for the total estimated
losses on uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income and
their effects are recognized in the period in which the revisions are
determined. An amount equal to contract costs attributable to claims is included
in revenues when realization is probable and the amount can be reliably
estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     The Company warrants labor and materials for the first year after
installation of new electrical systems. A reserve for warranty costs is recorded
based upon the historical level of warranty claims and management's estimate of
future costs.
 
  Accounts Receivable and Provision for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable, as well as provides a general reserve for potential unknown
adjustments.
 
  Income Taxes
 
     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their share of the
Company's taxable earnings or losses in their personal tax returns.
Consequently, the accompanying financial statements of the Company do not
include a provision for current or deferred income taxes. The Company intends to
terminate its S Corporation status concurrently with the effective date of the
Offering.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 9 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective November 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of

recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

5. LINE OF CREDIT:
 
   
     The Company has three lines of credit with a bank totaling $1,140,000 of
available credit. The line of credit expires January 1998 and bears interest at
9 percent. The line of credit is unsecured. At September 30, 1997, borrowings
outstanding under the line of credit were $540,000.
    
 
6. EMPLOYEE BENEFIT PLAN:
 
   
     The Company has a defined 401(k) contribution profit-sharing plan. The Plan
provides for the Company to match one-half of the first 5 percent contributed by
each employee. Total contributions by the Company under the plan were
approximately $83,000, $93,000 and $85,000 for the years ending December 31,
1995, 1996 and September 31, 1997 respectively. The Company may also make
discretionary contributions. The Company declared discretionary contributions of
$70,000 and $65,000 for the years ended December 31, 1995 and 1996,
respectively, and had accrued approximately $74,000 at December 31, 1996,
relating to all contributions to be funded in the subsequent fiscal year.
    
 
7. RELATED-PARTY TRANSACTIONS:
 
   
     The Company periodically will obtain loans from the stockholder to meet
current cash needs. The Company will also loan out excess funds to the
stockholder. Loans neither to nor from the stockholder are charged interest. A
total of $172,000 was due from a stockholder at September 30, 1997.
    
 
     The Company has an outstanding trade receivable in the amount of $74,000 to
a company owned by a member of the stockholder's family.
 
     The Company also provides real estate management services to a company
owned by the stockholder.
 
   
     The Company leases facilities from the Company's stockholder. The leases
expire annually. The rent paid under these related-party leases was
approximately $95,000, $118,000 and $115,000 for the years ended December 31,
1995 and 1996 and September 30, 1997, respectively.
    
 
8. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, accounts payable, lines of credit, notes payable and
long-term debt. The Company believes that the carrying value of these
instruments on the accompanying balance sheets approximates their fair value.

9. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, workers compensation and an umbrella policy.
The Company has not incurred significant uninsured losses on any of these items.
 
   
     The Company is self-insured for medical claims up to $20,000 per year per
covered individual. Claims in excess of these amounts are covered by a stop-loss
policy. The Company has recorded reserves for its portion of self-insured claims
based on estimated claims incurred through December 31, 1995 and 1996 or 1997.
    
 
10. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company did not have sales greater than 10 percent of total sales to
any one customer during the years ended December 31, 1994, 1995 and 1996 or
September 30, 1997.
    
 
   
     In addition, the Company grants credit, generally without collateral, to
its customers located primarily in the Midwest region. Consequently, the Company
is subject to potential credit risk related to changes in business and economic
factors within the Midwest. However, management believes that its contract
acceptance, billing and collection policies are adequate to minimize the
potential credit risk.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Pollock Electric Inc.:
 
   
     We have audited the accompanying balance sheets of Pollock Electric Inc., a
Texas Corporation, as of October 31, 1995 and 1996 and September 30, 1997, and
the related statements of operations, cash flows and stockholder's equity for
the years then ended. 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 Pollock Electric Inc. as of
October 31, 1995 and 1996 and September 30, 1997, and the results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
     Pollock Electric Inc., a Texas corporation (the Company), provides
electrical system installation, data and fiber optic cabling installation and
repair services primarily for mid-sized to large commercial facilities. The
Company performs the majority of its contract work under fixed price contracts,
with contract terms generally ranging from one to 12 months. The Company
performs the majority of its work in the commercial and industrial markets in
Harris County, Texas, and surrounding areas.
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the eleven months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation expense was
$64,144, $107,242 and $131,190 for the years ended October 31, 1995 and 1996 and
September 30, 1997, respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools,
repairs and depreciation costs. Provisions for the total

                             POLLOCK ELECTRIC INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions, estimated
profitability and final contract settlements may result in revisions to costs
and income and their effects are recognized in the period in which the revisions
are determined. An amount equal to contract costs attributable to claims is
included in revenues when realization is probable and the amount can be
reasonably estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor and materials for the
first year after installation of new electrical systems. The Company generally
warrants labor for one year after servicing existing electrical systems. A
reserve for warranty costs is recorded based upon the historical level of
warranty claims and management's estimate of future costs.
 
  Accounts Receivable and Provision for Doubtful Accounts
 
   
     Accounts receivable at October 31, 1995 and 1996 and September 30, 1997,
include immaterial amounts of claims and unapproved change orders, however, the
Company generally does not recognize change orders until they are approved.
    
 
     The Company provides an allowance for doubtful accounts based upon a
percentage of gross sales revenue. In addition, the Company reserves for
specific accounts when collection of such accounts is no longer probable.
 
  Income Taxes
 
     The Company follows the asset and liability method of accounting for income
taxes in accordance with Statement of Financial Accounting Standards (SFAS) No.
109. Under this method, deferred tax assets and liabilities are recorded for
future tax consequences of temporary differences between the financial reporting
and tax bases of assets and liabilities, and are measured using the enacted tax
rates and laws.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 11 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective November 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of

recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

5. LINE OF CREDIT:
 
   
     The Company has a $2,500,000 line of credit with a bank. At October 31,
1995 and 1996 and September 30, 1997, unpaid borrowings were $625,000,
$1,350,000 and $1,610,000, respectively. The line of credit expires February 28,
1998, and bears interest at the bank's prime lending rate plus 1 percent. The
line of credit is personally guaranteed by Jon Pollock, sole stockholder and
president of the Company, and is secured by all accounts, contract rights,
chattel paper, instruments, general intangibles, rights to payments of any kind,
all interest of the Company in any goods, and a blanket lien of all property and
equipment. The borrowing base is limited to 75 percent of eligible accounts
receivable that are outstanding less than 60 days from the invoice date.
    
 
   
     Interest is computed monthly on the unpaid balance and is payable monthly.
The Company has restrictive and various financial covenants with which the
Company was in compliance at September 30, 1997.
    
 
6. LEASES:
 
     The Company leases its office space from its sole stockholder and president
under a lease agreement with a primary lease term of one year beginning November
15, 1991. At the expiration of the primary lease term, the Company exercised its
option to extend the lease for an additional five-year period. Effective
November 1, 1995, the lease agreement was modified to include additional office
space. The basic rent was increased to $3,000 per month, and the expiration date
was extended to November 30, 1998.
 
   
     In addition to the basic lease cost, the Company must pay insurance, actual
taxes, maintenance and other operating costs. The rent paid under this
related-party lease was approximately $20,000, $36,000 and $36,000 for the years
ended October 31, 1995 and 1996 and September 30, 1997, respectively.
    
 
     Future minimum lease payments under this noncancelable operating lease are

     Certain vehicles and equipment have been leased under terms that constitute
capital leases. Accordingly, the costs of the assets (the lower of the cash
purchase price or the present value of the future minimum lease payments) were
recorded as an addition to property and the related liabilities were recorded as
lease obligations. The assets are amortized using the straight-line method, and
interest expense is recorded on the basis of the outstanding lease obligation.

8. RELATED-PARTY TRANSACTIONS:
 
   
     The Company leases its office space from its sole stockholder and
president. Total payments made under this lease agreement were approximately
$20,000, $36,000, and $36,000 for the years ended October 31, 1995 and 1996 and
September 30, 1997, respectively. (See Note 6).
    
 
     In 1995, the Company encouraged its employees to purchase personal
computers by making the down payments for the purchases. The employees are
repaying the Company through payroll deductions. The outstanding amounts are
classified as accounts receivable, other in the accompanying balance sheets.
 
9. EMPLOYEE BENEFIT PLANS:
 
  Stock Appreciation Plan
 
     On May 4, 1994, the Company adopted a stock appreciation rights plan titled
the Stock Unit Plan (the Plan). Under the Plan, stock rights or units were
awarded to employees valued at the book value of the
 
                                      F-81

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
Company's stock at that date. Subsequent increases in the book value of the
stock accrue to the benefit of the officer or employee, while decreases in the
book value reduce accrued benefits. Payments of amounts accrued under the Plan
are payable at retirement or resignation from the Company, except for cases of
termination with cause, at which time the units and benefits are forfeited.
Deferred compensation liability accrued under the Plan totaled $11,500, $17,435
and $17,435 at October 31, 1995 and 1996 and September 30, 1997, respectively.
The change in the value of the stock appreciation rights under the Plan are
recorded as compensation expense as the Company's net book value fluctuates.
    
 
  Stock Purchase Agreement
 
     The Company has entered into various agreements with certain of its
officers to provide for business continuity in the event of the death of the
Company's president and sole stockholder. The agreements provide for the
purchase of life insurance on the Company's president through split-dollar
arrangements and term insurance to provide funds for the officers of the Company
to acquire the president's stock in the event of his death. All amounts advanced
by the Company to pay premiums that are not subject to reimbursement from the
officers shall be collectible by the Company from the net equity of the
insurance policy or from the proceeds paid thereon.
 
  Profit-Sharing and 401(k) Plan
 
   
     Effective November 1, 1994, the Company established a defined contribution
plan for its employees. Employees over the age of 21 are eligible to participate
after one year of service with the Company. Under this plan, employees may elect
to defer up to 15 percent of their salary, subject to Internal Revenue Code
limits. The Company may make a discretionary match as well as a discretionary
profit-sharing contribution. The Company's contribution for the years ended
October 31, 1995 and 1996, totaled $16,970 and $22,466, respectively, and the
Company has accrued approximately $21,500 at September 30, 1997, for
contributions to be funded in the subsequent fiscal year.
    
 
10. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, accounts payable, a line of credit and notes payable. The
Company believes that the carrying value of these instruments on the
accompanying balance sheets approximates their fair value.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, workers' compensation, general liability and an umbrella policy.
The Company has not incurred significant uninsured losses on any of these items.
 
12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company had sales of approximately 16 percent of total sales to one
major customer during the years ended October 31, 1995 and 1996. During the year
ended September 30, 1997, the Company had sales of approximately 11% and 10% of
total sales to two major customers.

     In addition, the Company grants credit, generally without collateral, to
its customers, which are general contractors located primarily in Harris County,
Texas, and surrounding areas. Consequently, the Company is subject to potential
credit risk related to changes in business and economic factors within the
commercial and industrial markets in this geographic region. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.
 
   
     The Company routinely maintains cash balances in financial institutions in
excess of federally insured limits.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
   
To Charles P. Bagby Company, Inc.:
    
 
   
     We have audited the accompanying balance sheets of Charles P. Bagby
Company, Inc., an Alabama S-Corporation, as of December 31, 1996 and September
30, 1997, and the related statements of operations, cash flows and stockholder's
equity for the years ended December 31, 1996 and September 30, 1997 and for the
nine months ended September 30, 1997. 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 Charles P. Bagby Company,
Inc. as of December 31, 1996 and September 30, 1997, and the results of its
operations and its cash flows for the years ended December 31, 1996 and
September 30, 1997, and for the nine months ended September 30, 1997, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
   
     Charles P. Bagby Company, Inc. (an Alabama S-Corporation), and its
majority-owned subsidiary, Haymaker Electric, Ltd. (collectively, the
"Company"), focuses on providing electrical system installation and repair
services primarily for mid-sized to large commercial facilities. The Company
performs the majority of its contract work under cost-plus-fee contracts and
fixed price contracts, with contract terms generally ranging from two to 18
months. The Company performs the majority of its work in the state of Alabama.
All significant intercompany activity has been eliminated in consolidation.
    
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid debt instruments with an original
maturity of three months or less when purchased to be cash equivalents.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation expense was
$21,000 for the year ended December 31, 1996, and $23,000 for the year ended
September 30, 1997.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract
 
                                      F-89

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
performance, such as indirect labor, supplies, tools, repairs and depreciation
costs. Provisions for the total estimated losses on uncompleted contracts are
made in the period in which such losses are determined. Changes in job
performance, job conditions, estimated profitability and final contract
settlements may result in revisions to costs and income and their effects are
recognized in the period in which the revisions are determined. An amount equal
to contract costs attributable to claims is included in revenues when
realization is probable and the amount can be reliably estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs.
 
  Provision for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
 
  Income Taxes
 
   
     The Company is an Alabama sub-chapter S corporation and is not subject to
federal income tax. The earnings of the Company are taxable to the individual
stockholder.
    
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 10 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective November 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairment would be to expense the difference between the fair value of such
property and its carrying value. Adoption of this standard did not have a
material effect on the financial position or results of operations of the
Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
5. LONG-TERM DEBT:
 
   
     The Company has a $650,000 line of credit with a bank. The line of credit
expires June 30, 1998, and bears interest at 1 percent over the prime lending
rate. The line of credit is secured by a stockholder of a partner corporation.
No borrowings were outstanding under this line of credit at December 31, 1996 or
September 30, 1997.
    
 
   
6. EMPLOYEE BENEFIT PLAN:
    
 
   
     The Company has a defined contribution profit-sharing plan. The plan
provides for the Company to match 3 percent of the gross salary of each employee
subject to certain limitations. All participants are immediately fully vested.
Total contributions by the Company under the plan were approximately $51,000 for
the year ended December 31, 1996, and $106,000 for the year ended September 30,
1997.
    
 
   
7. FINANCIAL INSTRUMENTS:
    
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, notes receivable, accounts payable, a line of credit and
short-term borrowings. The Company believes that the carrying value of these
instruments on the accompanying balance sheets approximates their fair value.
 
   
8. COMMITMENTS AND CONTINGENCIES:
    
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant uninsured losses on any of these items.
 
   
9. MAJOR CUSTOMERS AND RISK CONCENTRATION:
    
 
   
     The Company had sales comprising approximately 10%, 11% and 11% of total
sales to three major customers during the years ended December 31, 1996 and
    
   
September 30, 1997.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Amber Electric, Inc.:
 
   
     We have audited the accompanying balance sheets of Amber Electric, Inc., a
Florida corporation, as of December 31, 1995 and 1996 and September 30, 1997,
and the related statements of operations, cash flows and stockholder's equity
for the years then ended. 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 Amber Electric, Inc. as of
December 31, 1995 and 1996 and September 30, 1997, and the results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
     Amber Electric, Inc. (the Company), a Florida corporation, focuses on
providing electrical system installation and repair services primarily for
residential and mid-sized to large commercial facilities. The Company performs
the majority of its contract work under fixed price contracts, with contract
terms generally ranging from two to 12 months. The Company performs the majority
of its work in central Florida.
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line and declining-balance methods over the estimated useful
lives of the related assets. Leasehold improvements are capitalized and
amortized over the estimated useful life of the asset. Depreciation and
amortization expense was approximately $62,000, $87,000 and $172,000 for the
years ended December 31, 1995, 1996, and September 30, 1997, respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools,
repairs and depreciation costs. Provisions for the total estimated losses on
uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income and
their effects are recognized in the period in which the revisions are
determined. An amount equal to contract costs attributable to claims is included
in revenues when realization is probable and the amount can be reliably
estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
one year after servicing of existing electrical systems.
 
  Allowance for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
 
  Income Taxes
 
     The Company follows the asset and liability method of accounting for income
taxes in accordance with Statement of Financial Accounting Standards (SFAS) No.
109. Under this method, deferred assets and liabilities are recorded for future
tax consequences of temporary differences between the financial reporting and
tax bases of assets and liabilities, and are measured using enacted tax rates
and laws.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote for discussion of significant
estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective November 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of
 
                                      F-99

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

8. RELATED-PARTY TRANSACTIONS:
 
     During 1995, the Company transferred its interest in the cash surrender
value of life insurance policies in exchange for a note receivable bearing
annual interest of 4 percent to a partnership controlled by the majority
stockholder of the Company. The entire principal and accrued interest is due
August 2005. The Company continues to pay premiums for this policy, also
increasing the receivable.
 
     The Company had a note payable to the majority stockholder at December 31,
1996, which represented a bonus to the stockholder and was loaned to the Company
without interest attached. The balance was subsequently paid to the stockholder.
 
     The Company will advance money to employees on occasion. Advanced amounts
are based on certain levels of employment and are repaid to the Company based on
a variety of repayment plans.
 
9. EMPLOYEE BENEFIT PLAN:
 
     The Company has a defined contribution profit-sharing plan. The plan
provides for the Company to match, on a discretionary basis, one-half of the
first 4 percent contributed by each employee. Total

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
contributions by the Company under the plan were approximately $31,000, $44,000
and $56,000 for the years ending December 31, 1995, 1996 and September 30, 1997,
respectively. The Company had accrued approximately $5,000 at September 30,
1997, for contributions to be funded in the subsequent fiscal year.
    
 
10. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, employee advances, notes receivable, a line of credit,
accounts payable, notes payable and long-term debt. The Company believes that
the carrying value of these instruments on the accompanying balance sheets
approximates their fair value.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is involved in disputes or legal actions arising in the
ordinary course of business. Management does not believe the outcome of such
legal actions will have a material adverse effect on the Company's financial
position or results of operations.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant uninsured losses on any of these items.
 
   
     The Company provides for workers' compensation insurance through a
partially self-insured plan whereby the Company is responsible for certain
incurred losses with a maximum of 125 percent of standard state-rated workers'
compensation premiums. Estimated claims incurred during the years ended December
31, 1995, 1996 and September 30, 1997 were not material. Accordingly, the
Company has not recorded any reserves for its portion of self-insurance claims.
During 1997, the Company enrolled in a secured individual preferred dividend
safety incentive program for workers' compensation with a maximum premium of 100
percent of the total normal state-rated premium. Employee health insurance is
provided for under a fully insured medical plan consisting of HMO and POS
programs.
    
 
12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company had sales of approximately 16 percent of total sales to one
major customer for the year ended December 31, 1995, sales of approximately 15
and 13 percent of total sales to two major customers for the year ended December
31, 1996, and sales of approximately 22 percent of total sales to one major
customer during the year ended September 30, 1997.
    
 
     In addition, the Company grants credit, generally without collateral, to
its customers, which are real estate operations, general contractors, etc.,
located primarily in central Florida. Consequently, the Company is subject to
potential credit risk related to changes in business and economic factors within
the central Florida region. However, management believes that its contract
acceptance, billing and collection policies are adequate to minimize the
potential credit risk.
 
   
     The Company routinely maintains cash balances in financial institutions in
    
   
excess of federally insured limits.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Daniel Electrical Contractors, Inc. and
  Daniel Electrical of Treasure Coast, Inc.:
 
   
     We have audited the accompanying combined balance sheets of Daniel
Electrical Contractors, Inc., a Florida corporation, and Daniel Electrical of
Treasure Coast, Inc., a Florida corporation, as of December 31, 1995 and 1996
and September 30, 1997, and the related combined statements of operations, cash
flows and stockholder's equity for the years then ended and for the nine months
ended September 30, 1997. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these combined 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 combined financial statements referred to above present
fairly, in all material respects, the combined financial position of Daniel
Electrical Contractors, Inc. and Daniel Electrical of Treasure Coast, Inc., as
of December 31, 1995 and 1996 and September 30, 1997, and the combined results
of their operations and their cash flows for the years then ended and for the
nine months ended September 30, 1997, in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
     Daniel Electrical Contractors, Inc. and Daniel Electrical of Treasure
Coast, Inc., (collectively, the Company), both Florida corporations focuses on
providing electrical system installation and repair services primarily for
residential and mid-sized to large commercial facilities. The Company performs
the majority of its contract work under fixed price contracts with contract
terms generally ranging from six to 18 months. The Company performs the majority
of its work in Dade County, Florida.
 
   
     The combined financial statements include the accounts of Daniel Electrical
Contractors, Inc. and Daniel Electrical of Treasure Coast, Inc. These entities
are related by virtue of common ownership. All material intercompany
transactions and balances have been eliminated in combination.
    
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings)of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1996 are unaudited and have been prepared pursuant to the rules and regulations
of the Securities and Exchange Commission. Accordingly, they do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of the Company's
management, the unaudited interim financial statements contain all adjustments
(consisting of normal recurring adjustments) considered necessary for a fair
presentation. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Investments
 
   
     Investments in securities are classified as securities available for sale
and consist of equity securities. Unrealized holding gains and losses on
securities available-for-sale are reported as net amount as a separate component
of stockholder's equity.
    
 
  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.
 
  Property and Equipment
 
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the
 
                                      F-110

                   DANIEL ELECTRICAL OF TREASURE COAST, INC.
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
lesser of the life of the lease or the estimated useful life of the asset.
Depreciation and amortization expense was $113,000, $125,000 and $142,000 for
the years ended December 31, 1995, 1996 and September 30, 1997, respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed, except when
work is being performed under a construction contract. Revenues from
construction contracts are recognized on the percentage-of-completion method
measured by the percentage of costs incurred to date to total estimated costs
for each contract. Contract costs include all direct material and labor costs
and those indirect costs related to contract performance, such as indirect
labor, supplies, tools, repairs and depreciation costs. Provisions for the total
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions, estimated
profitability and final contract settlements may result in revisions to costs
and income and their effects are recognized in the period in which the revisions
are determined. An amount equal to contract costs attributable to claims is
included in revenues when realization is probable and the amount can be reliably
estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs.
 
  Accounts Receivable and Allowance for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
 
  Income Taxes
 
     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company itself is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their share of the
Company's taxable earnings or losses in their personal tax returns.
Consequently, the accompanying financial statements of the Company do not
include a provision for current or deferred income taxes. The Company intends to
terminate its S Corporation status concurrently with the effective date of the
Offering.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 10 for discussion of
significant estimates reflected in the Company's combined financial statements.
    
 
  New Accounting Pronouncement
 
   
     Effective November 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairments would be to expense the difference between the fair value of such
property and its carrying value. Adoption of this standard did not have a
material effect on the combined financial position or results of operations of
the Company.

     The Company had sales of approximately 32 percent and 21 percent of total
sales to two major customers during the year ended December 31, 1995, sales of
approximately 29 percent and 25 percent of total sales to two major customers
during the year ended December 31, 1996, and sales of approximately 30 percent
and 38 percent of total sales to two major customers during the year ended
September 30, 1997.
    
 
     In addition, the Company grants credit, generally without collateral, to
its customers, which are general contractors located primarily in southern
Florida. Consequently, the Company is subject to potential credit risk related
to changes in business and economic factors within the southern Florida region.
However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.
 
   
     The Company routinely maintains cash balances in financial institutions in
    
   
excess of federally insured limits.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
     Summit Electric of Texas, Inc. (the Company), a Texas corporation, focuses
on providing electrical system installation and repair services primarily for
mid-sized to large commercial facilities. The Company performs the majority of
its contract work under fixed price contracts, with contract duration generally
ranging from two to eight months. The Company performs the majority of its work
primarily in Houston, Texas.
 
   
     On a limited basis, the Company provides auto repair and restoration
services to its sole stockholder (the Stockholder) and third parties. The
revenues and cost of services related to such activities have not been removed
from the Company's results of operations for the year ended March 31, 1997 and
September 30, 1997, as such amounts are not material.
    
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the six months ended September 30,
1996 and 1997, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using an accelerated method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation expense was
$72,101 and $75,358 for the years ended March 31, 1997 and September 30, 1997,
respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-
 
                                      F-121
<PAGE>   200
 
                         SUMMIT ELECTRIC OF TEXAS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
completion method measured by the percentage of costs incurred to date to total
estimated costs for each contract. Contract costs include all direct material
and labor costs and those indirect costs related to contract performance, such
as indirect labor, supplies, tools, repairs and depreciation costs. Provisions
for the total estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in job performance, job conditions,
estimated profitability and final contract settlements may result in revisions
to costs and income, and their effects are recognized in the period in which the
revisions are determined. An amount equal to contract costs attributable to
claims is included in revenues when realization is probable and the amount can
be reliably estimated.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs.
 
  Accounts Receivable and Provision for Doubtful Accounts
 
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
 
  Income Taxes
 
     The Company follows the asset and liability method of accounting for income
taxes in accordance with Statement of Financial Accounting Standards (SFAS) No.
109. Under this method, deferred assets and liabilities are recorded for future
tax consequences of temporary differences between the financial reporting and
tax bases of assets and liabilities and are measured using enacted tax rates and
laws.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities and
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 11 for discussion of
significant estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective April 1, 1996, the Company adopted SFAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of
recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
property is necessary. The effect of any impairment would be to expense the
difference between the fair value of such property and its carrying value.
Adoption of this standard did not have a material effect on the financial
position or results of operations of the Company.

     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, workers' compensation and an umbrella policy.
The Company has not incurred significant uninsured losses on any of these items.

     In addition, the Company grants credit, generally without collateral, to
its customers, which are primarily general contractors located in Houston,
Texas. Consequently, the Company is subject to potential credit risk related to
changes in business and economic factors within Houston, Texas. However,
management believes that its contract acceptance, billing and collection
policies are adequate to minimize the potential credit risk.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Thurman & O'Connell Corporation:
 
   
     We have audited the accompanying balance sheets of Thurman & O'Connell
Corporation, a Kentucky corporation, as of December 31, 1995 and 1996 and
September 30, 1997, and the related statements of operations, cash flows and
stockholders' equity for the years then ended. 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 Thurman & O'Connell
Corporation as of December 31, 1995 and 1996 and September 30, 1997, and the
results of its operations and its cash flows for the years then ended in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BUSINESS AND ORGANIZATION:
 
   
     Thurman & O'Connell Corporation (the Company), a Kentucky corporation,
focuses on providing electrical system installation and repair services
primarily to large commercial facilities. The Company performs the majority of
its contract work under fixed price contracts, with contract terms generally
ranging from 12 to 24 months. The Company performs the majority of its work in
Kentucky.
    
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Interim Financial Information
 
   
     The interim financial statements for the nine months ended September 30,
1997 and 1996, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim financial statements contain all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation. The results of operations for the interim periods are
not necessarily indicative of the results for the entire fiscal year.
    
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
maintains its principal cash balances in one financial institution. The balances
are insured by the Federal Deposit Insurance Corporation up to $100,000.
 
  Inventories
 
     Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.
 
  Property and Equipment
 
   
     Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Depreciation expense was approximately $53,000, $49,000 and $52,000 for the
years ended December 31, 1995 and 1996 and September 30, 1997, respectively.
    
 
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
 
  Revenue Recognition
 
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
completion method measured by the percentage of costs incurred to date to total
estimated costs for each contract. Contract costs include all direct material
and labor costs and those indirect costs related to contract performance, such
as indirect labor, supplies, tools, repairs and depreciation costs. Provisions
for the total estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in job performance, job conditions,
estimated profitability and final contract settlements may result in revisions
to costs and income and their effects are recognized in the period in which the
revisions are determined.
 
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.
 
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
 
  Warranty Costs
 
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems.
 
  Income Taxes
 
   
     The stockholders of the Company have elected S Corporation status as
defined by the Internal Revenue Code, whereby the Company itself is not subject
to taxation for federal purposes. Under S Corporation status, the stockholders
report their share of the Company's taxable earnings or losses in their personal
tax returns. The provision for income taxes in the accompanying financial
statements relates to income and other taxes incurred by the Company in those
localities that do not permit the Company to report its net income with that of
its stockholders (S Corporation treatment). The Company intends to terminate its
S Corporation status concurrently with the effective date of the Offering (as
defined in Note 1).
    
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities,
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote for discussion of significant
estimates reflected in the Company's financial statements.
 
  New Accounting Pronouncement
 
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if an impairment of such property is necessary. The effect of any
impairment would be to expense the difference between the fair value of such
property and its carrying value. Adoption of this standard did not have a
material effect on the financial position or results of operations of the
Company.

5. LONG-TERM DEBT:
 
   
     During 1996, the Company refinanced the note payable to a bank which was in
place at December 31, 1995, with a variable rate note payable. The note is
payable in monthly principal and interest payments of $1,051 through October
2004, at which time any unpaid principal and interest is due. The note is
collateralized by a cash account at the bank, and the Company has agreed not to
pay dividends in excess of the Company's net income for any fiscal year.
Interest is based upon a variable rate of 1% above the rate being offered on the
sweep account (6% as of December 31, 1996 and September 30, 1997).
    
 
     At December 31, 1995, the Company had a note payable to a bank which
required monthly principal payments of $1,051 plus interest at the prime rate
(8.25% at December 31, 1995) through July 2008. Under the agreement, the Company
agreed not to pay dividends in excess of the Company's net income for the year.
The note was collateralized by the Company's land and building.
 
   
     The approximate aggregate maturities of long-term debt as of September 30,
1997, are as follows (in thousands):

     The Company has a $1,000,000 line of credit with a bank. The line of credit
expires in April 1998 and bears interest at the prime lending rate. All
receivables are pledged as collateral under the agreement, and the Company has
agreed not to pay dividends in excess of net income for the year and to maintain
its deposit accounts with the bank. There were no borrowings under this
agreement at December 31, 1996 or September 30, 1997. In 1995, the Company had a
$500,000 unsecured line of credit at prime with a bank, which expired in April
1996. There were no borrowings under this agreement during 1995 or 1996.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
6. RELATED-PARTY TRANSACTIONS:
 
   
     The Company earned revenue for electrical contracting services from
companies owned by a stockholder of approximately $47,000, $40,000 and $25,000
for the years ended December 31, 1995 and 1996, and September 30, 1997,
respectively, with approximately $1,000, $2,000 and $4,000 of the revenue being
recorded as receivables at the respective balance sheet dates. In addition, the
Company had a receivable from another stockholder in the amount of approximately
$1,000, $2,000 and $5,000 as of December 31, 1995 and 1996 and September 30,
1997, respectively, related to travel expense advances.
    
 
7. EMPLOYEE BENEFIT PLAN:
 
   
     During 1995, the Company adopted a defined contribution 401(k) savings plan
covering employees meeting certain minimum service and age requirements, as
defined. The plan provides for discretionary contributions on the part of the
Company. For the years ended December 31, 1995 and 1996 and September 30, 1997,
the Company elected to match 100% of the first 2 percent contributed by each
employee. The contributions paid by the Company totaled approximately $9,000,
$12,000 and $8,000 for the years ended December 31, 1995 and 1996 and September
30, 1997, respectively.
    
 
8. FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, accounts payable, a line of credit, and long-term debt. The
Company believes that the carrying value of these instruments on the
accompanying balance sheets approximates their fair value.
 
9. STOCKHOLDERS' AGREEMENT:
 
   
     The Company has a right of first refusal on any stock voluntarily offered
for sale by a stockholder subject to certain terms and conditions. The
redemption price shall be as determined by the stockholders on an annual basis
or by formula which is contained in the agreement if a value has not been
established by the stockholders. Such redemption price is payable in not more
than 10 equal quarterly installments with interest at the prime rate. As of
September 30, 1996 and December 31, 1996, the redemption price was determined to
be $5.141 per share.
    
 
   
     Upon the death of any stockholder, the Company shall redeem the stock held
by such stockholder provided that the redemption is requested in writing by the
personal representative of the deceased stockholder within two months of the
appointment of such representative or the Company elects to redeem such stock
within the same two-month period. The redemption price pursuant to this
paragraph is the same as described above. Such redemption price may be paid in
full at the closing or in installments, the down payment being the greater of
one-fifth of redemption price or any life insurance proceeds received by the
Company resulting from the death of the stockholder with the balance payable in
quarterly installments over not more than five years with interest at the prime
rate. Coverage under the key-man term life insurance purchased by the Company
totaled $1,000,000 as of December 31, 1995 and 1996, and September 30, 1997.
    
 
10. DIVIDENDS:
 
     As long as the election made by the stockholders to report the operations
of the Company on their individual federal and state income tax returns remains
in effect, the board of directors of the Company is required to declare a
dividend, subsequent to the close of the Company's tax year and prior to the
date when payment of individual income taxes is required, to provide the
stockholders sufficient cash to pay any applicable individual income taxes
resulting from the inclusion of the Company's taxable income on their individual
income tax returns. In addition, at the discretion of the Company's board of
directors, an additional

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
minimum dividend shall be authorized which, when combined with the dividend
required to meet the tax obligations of the shareholders, shall equal not less
than 50 percent of the net pretax income of the Company.
 
11. COMMITMENTS AND CONTINGENCIES:
 
  Litigation
 
     The Company is not currently involved in any significant disputes or legal
actions, however, such actions could arise in the ordinary course of business.
 
  Insurance
 
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability and an umbrella policy. The Company has not
incurred significant uninsured losses on any of these items.
 
12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
 
   
     The Company had sales of approximately 25, 18, 12, 12 and 11 percent of
total sales to five major customers during 1995, sales of approximately 48, 11
and 10 percent of total sales to three major customers during 1996 and sales of
approximately 26, 12 and 12 percent of total sales to three major customers
during the year ended September 30, 1997.
    
 
   
     In addition, the Company grants credit, generally without collateral, to
its customers, which are general contractors in the commercial and industrial
construction markets in Kentucky. Consequently, the Company is subject to
potential credit risk related to changes in business and economic factors within
the commercial and industrial construction markets in this state. However,
management believes that its contract acceptance, billing and collection
    
   
policies are adequate to minimize the potential credit risk.

                         NOTES TO FINANCIAL STATEMENTS
    
 
   
1. BUSINESS AND ORGANIZATION:
    
 
   
  Principles of Presentation
    
 
   
     Rodgers Electric Company, Inc. is a Washington corporation. The Company
provides electrical contracting services to commercial and industrial customers
in Western Washington. Most of the Company's revenue is from partnering with
customers and providing engineering services for design-build projects on a time
and material basis with a guaranteed not-to-exceed price.
    
 
   
     In October 1997, the Company and its stockholders entered into a definitive
agreement with Integrated Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock will be exchanged for cash and
shares of IES common stock, concurrent with the consummation of the initial
public offerings in the United States and Canada and outside the United States
and Canada (the Offerings) of additional common stock by IES. In addition, the
key executives of the Company entered into employment agreements with the
Company and IES which have an initial term of five years, and generally restrict
the disclosure of confidential information as well as restrict competition with
the Company and IES for a period of two years following termination of
employment.
    
 
   
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
    
 
   
  Cash and Cash Equivalents
    
 
   
     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
    
 
   
  Property and Equipment
    
 
   
     Property and equipment are stated at cost, and depreciation is computed
using an accelerated method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset. Depreciation expense was
approximately $25,000 and $47,000 for the years ended March 31, 1997 and
September 30, 1997, respectively.
    
 
   
     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.
    
 
   
  Revenue Recognition
    
 
   
     The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to date to total estimated costs for each contract.
Contract costs include all direct material and labor costs and those indirect
costs related to contract performance, such as indirect labor, supplies, tools,
repairs and depreciation costs. Provisions for the total estimated losses on
uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income, and
their effects are recognized in the period in which the revisions are
determined. An amount equal to contract costs attributable to claims is included
in revenues when realization is probable and the amount can be reliably
estimated.
    
 
   
     The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance at each balance sheet
date will be collected within the subsequent fiscal year.

                         RODGERS ELECTRIC COMPANY, INC.
    
 
   
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents billings in excess of revenues
recognized.
    
 
   
  Warranty Costs
    
 
   
     For certain contracts, the Company warrants labor for the first year after
installation of new electrical systems. The Company generally warrants labor for
30 days after servicing of existing electrical systems. A reserve for warranty
costs is recorded based upon the historical level of warranty claims and
management's estimate of future costs. A reserve for warranty costs is recorded
based upon the historical level of warranty claims and management's estimate for
future costs.
    
 
   
  Accounts Receivable and Provision for Doubtful Accounts
    
 
   
     The Company provides an allowance for doubtful accounts based upon the
specific identification of accounts receivable where collection is no longer
probable.
    
 
   
  Income Taxes
    
 
   
     The Company follows the asset and liability method of accounting for income
taxes in accordance with Statement of Financial Accounting Standards (SFAS) No.
109. Under this method, deferred assets and liabilities are recorded for future
tax consequences of temporary differences between the financial reporting and
tax bases of assets and liabilities and are measured using enacted tax rates and
laws.
    
 
   
  Use of Estimates
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities and
disclosures of contingent liabilities at the date of the financial statements
and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. Reference is made to the
"Revenue Recognition" section of this footnote and Note 11 for discussion of
significant estimates reflected in the Company's financial statements.
    
 
   
  New Accounting Pronouncement
    
 
   
     Effective April 1, 1996, the Company adopted SFAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment or other assets may be impaired, an evaluation of
recoverability would be performed. If an evaluation is required, the estimated
future undiscounted cash flows associated with the asset are compared to the
asset's carrying amount to determine if an impairment of such property is
necessary. The effect of any impairment would be to expense the difference
between the fair value of such property and its carrying value. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

recognition of income and expenses for financial reporting purposes and for tax
purposes. The tax effects of these temporary differences, representing deferred
tax assets result principally from the following (in thousands):

9. EMPLOYEE BENEFIT PLAN:
    
 
   
     The Company has a profit sharing plan which covers substantially all
qualified employees. The profit sharing contribution is made at the discretion
of the Directors. Benefits payable under the profit sharing plan are limited to
contributions made and earnings therein. Company contributions for the year
ended September 30, 1997 were $192,000.
    
 
   
10. FINANCIAL INSTRUMENTS:
    
 
   
     The Company's financial instruments consist of cash and cash equivalents,
accounts receivable, notes receivable, accounts payable, and short and long-term
debt. The Company believes that the carrying values of these instruments on the
accompanying balance sheets approximate their fair values.
    
 
   
11. COMMITMENTS AND CONTINGENCIES:
    
 
   
  Litigation
    
 
   
     The Company is periodically involved in disputes or legal actions arising
in the ordinary course of business. Management does not believe the outcome of
such legal actions will have a material adverse effect on the Company's
financial position or results of operations.
    
 
   
  Insurance
    
 
   
     The Company carries a broad range of insurance coverage, including business
auto liability, general liability, workers' compensation and an umbrella policy.
    
 
   
12. MAJOR CUSTOMERS AND RISK CONCENTRATION:
    
 
   
     The Company had sales greater than 10% of total sales to three major
customers, comprising approximately 25%, 22% and 13% of sales during the year
ended September 30, 1997.
    
 
   
     In addition, the Company grants credit, generally without collateral, to
its customers, which are primarily commercial and industrial companies located
in the North Puget Sound area of Western Washington. Consequently, the Company
is subject to potential credit risk related to changes in business and economic
factors in that area. However, management believes that its contract acceptance,
billing and collection policies are adequate to minimize the potential credit
    
   
risk.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Subsection (a) of section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent 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, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
 
     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
made to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the 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.
 
     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
action, suit or proceeding referred to in subsections (a) and (b) of Section 145
in the defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith; that indemnification provided for by Section 145
shall not be deemed exclusive of any other rights to which the indemnified party
may be entitled; that indemnification provided for by Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of such person's heirs, executors and administrators; and empowers the
 
                                      II-1

corporation to purchase and maintain insurance on behalf of a director or
officer of the corporation against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such
whether or not the corporation would have the power to indemnify him against
such liabilities under Section 145.
 
     Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that such provision shall not eliminate or limit the liability of a
director (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.
 
     Article Eighth of the Company's Amended and Restated Certificate of
Incorporation states that:
 
     No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty by such director as a director; provided, however, that this Article Eighth
shall not eliminate or limit the liability of a director to the extent provided
by applicable law (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 DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. No amendment to or repeal of this Article
Eighth shall apply to, or have any effect on, the liability or alleged liability
of any director of the Corporation for or with respect to any acts or omissions
of such director occurring prior to such amendment or repeal. If the DGCL 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 DGCL, as so amended.
 
     In addition, Article VI of the Company's Bylaws further provides that the
Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.
 
     The Company intends to enter into indemnification agreements with each of
its executive officers and directors.
 
   
     Under Section 6 of the U.S. and International Purchase Agreements filed as
Exhibits 1.1 and 1.2 to this Registration Statement, the Underwriters have
agreed to indemnify, under certain conditions, the Company, its officers and
directors, and persons who control the Company within the meaning of the
Securities Act of 1933, as amended, against certain liabilities.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.
 
     The undersigned registrant hereby undertakes:
 
          (1) That for purposes of determining any liability under the
     Securities Act of 1933, 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(h) under the Securities Act shall be deemed to be
     part of this Registration Statement as of the time it was declared
     effective.
 
          (2) That for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment that contains a form
     of prospectus shall be deemed to be a new registration
 
                                      II-4

     statement relating to the securities offered therein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
   
          (3) To provide to the Underwriters at the closing specified in the
     underwriting agreement certificates in such denominations and registered in
     such names as required by the Underwriters to permit prompt delivery to
     each purchaser.

Stock"), offered hereby are being offered by Integrated Electrical Services,
Inc. (the "Company").
    
 
   
    Of the shares of Common Stock being offered hereby, 1,400,000 shares (the

underwriting discount per share are identical for both Offerings and the
closings for both Offerings are conditioned upon each other. See "Underwriting."
    
 
   
    Prior to the Offerings, there has been no public market for the Common
Stock. It is currently estimated that the initial public offering price will be
between $  and $  per share. See "Underwriting" for information relating to the
factors to be considered in determining the initial public offering price.
Shares of Common Stock are being reserved for sale to certain employees,
directors and business associates of, and certain other persons designated by,

and other persons are expected to purchase, in the aggregate, not more than 10%

     Certain persons participating in the Offerings may engage in transactions

     The Company has also entered into a U.S. purchase agreement (the "U.S.
Purchase Agreement") with certain other underwriters in the United States and
Canada (the "U.S. Underwriters" and, together with the International Managers,
the "Underwriters"), for whom Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Donaldson, Lufkin & Jenrette Securities Corporation, Equitable
Securities Corporation and Sanders Morris Mundy Inc. are acting as
representatives. Subject to the terms and conditions set forth in the U.S.
Purchase Agreement, and concurrently with the sale of 1,400,000 shares of Common
Stock to the International Managers pursuant to the International Purchase
Agreement, the Company has agreed to sell to the U.S. Underwriters, and the U.S.
Underwriters severally have agreed to purchase from the Company, an aggregate of
5,600,000 shares of Common Stock. The public offering price per share of Common
Stock and the total underwriting discount per share are identical under the
International Purchase Agreement and the U.S. Purchase Agreement.
    
 
   
     In the International Purchase Agreement and the U.S. Purchase Agreement,
the several International Managers and the several U.S. Underwriters,
respectively, have agreed, subject to the terms and conditions set forth
therein, to purchase all of the shares of Common Stock being sold pursuant to
each such Purchase Agreement if any of such shares being sold pursuant to each
such Purchase Agreement are purchased. Under certain circumstances, the
commitments of non-defaulting International Managers or U.S. Underwriters (as
the case may be) may be increased as set forth in the International Purchase
Agreement and the U.S. Purchase Agreement, respectively. The closing with
respect to the sale of shares of Common Stock to be purchased by the
International Managers and the U.S. Underwriters are conditioned upon one
another.
    
 
   
     The International Managers and the U.S. Underwriters have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for the
coordination of their activities. Under the terms of the Intersyndicate
Agreement, the Underwriters are permitted to sell shares of Common Stock to each
other for the purposes of resale at the public offering price, less an amount
not greater than the selling concession. Under the terms of the Intersyndicate
Agreement, the International Managers and any dealer to whom they sell shares of
Common Stock will not offer to sell or sell shares of Common Stock to persons
who are United States or Canadian persons or to persons they believe intend to
resell to persons who are United States or
    
<PAGE>   240
 
                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
 
   
Canadian persons, and the U.S. Underwriters and any dealer to whom they sell
shares of Common Stock will not offer to sell or sell shares of Common Stock to
persons who are non-United States and non-Canadian persons or to persons they
believe intend to resell to persons who are non-United States persons or non-
Canadian persons, except, in each case, for transactions pursuant to the
Intersyndicate Agreement.
    
 
   
     The Lead Managers have advised the Company that the International Managers
propose initially to offer the shares of Common Stock to the public at the
initial public offering price set forth on the cover page of this Prospectus,
and to certain dealers at such price less a concession not in excess of $
per share. The International Managers may allow, and such dealers may reallow, a
discount not in excess of $     per share to certain other dealers. After the
Offerings, the initial public offering price, concession and discount may be
changed.
    
 
   
     The Company has granted the International Managers an option, exercisable
by the Lead Managers for 30 days after the date of this Prospectus, to purchase
up to an aggregate of 240,000 additional shares of Common Stock at the initial
public offering price set forth on the cover page hereof, less the underwriting
discount. The International Managers may exercise this option to cover
overallotments, if any, made on the sale of the shares of Common Stock offered
hereby. If the International Managers exercise this option, each International
Manager will have a firm commitment, subject to certain conditions, to purchase
approximately the same percentage thereof which the number of shares of Common
Stock to be purchased by it shown in the foregoing table bears to the 1,400,000
shares of Common Stock initially offered hereby. The Company has also granted an
option to the U.S. Underwriters, which expires 30 days after the date of this
Prospectus, to purchase up to 810,000 additional shares of Common Stock to cover
over-allotments, if any, on terms similar to those granted to the International
Managers.
    
 
   
     The Company and each of its directors and executive officers have agreed
not to (i) directly or indirectly, offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant for the sale of, or otherwise transfer or
dispose of any shares of Common Stock or any securities convertible into or
exchangeable or exercisable for Common Stock or file any registration statement
under the Securities Act with respect to any of the foregoing or (ii) enter into
any swap or any other agreement or any transaction that transfers, in whole or
in part, directly or indirectly, the economic consequence of ownership of the
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock whether any such swap or transaction described in clause (i) or
(ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise, for a period of 180 days from the date of this
Prospectus without the prior written consent of Merrill Lynch, Pierce, Fenner &
Smith Incorporated on behalf of the Underwriters, except for (i) shares issued
in connection with acquisitions, provided that (except with respect to shares
issued in transactions in which the issuance or resale of such shares is not
registered under the Securities Act), the recipients of such shares agree to be
bound by similar restrictions and (ii) any shares of Common Stock issued or
options to purchase Common Stock granted pursuant to the Company's benefit plans
described herein.
    
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments the Underwriters may be required to make in respect thereof.
 
   
     Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase the Common Stock. As an exception to these
rules, the U.S. Underwriters are 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 pegging, fixing or maintaining the price of the
Common Stock.
    
 
   
     If the Underwriters create a short position in the Common Stock in
connection with the Offering, (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the U.S. Underwriters
may reduce that short position by purchasing Common Stock in the open market.
The U.S.
    
<PAGE>   241
 
                 [ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS]
 
Underwriters may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.
 
   
     The U.S. Underwriters may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the U.S. Underwriters purchase
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 and selling group members
who sold those shares as part of the Offerings.
    
 
     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 affect on the price of a security to the extent that it were
to discourage 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 U.S.
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
    
 
     The Company intends to make application to list the Common Stock on the
NYSE under the symbol "IEE."
 
   
     The U.S. Underwriters have reserved for sale, at the initial public
offering price, up to 700,000 shares of Common Stock for certain employees,
directors and business associates of, and certain other persons designated by,
the Company who have expressed an interest in purchasing such shares of Common
Stock. The number of shares available for sale to the general public in the
Offerings will be reduced to the extent such persons purchase such reserved
shares. Any reserved shares not so purchased will be offered to the general
public on the same basis as other shares offered hereby.
    
 
   
     Prior to the Offerings, there has been no established trading market for
the shares of Common Stock. The initial public offering price for the Common
Stock offered hereby has been determined by negotiations between the Company and
the Underwriters. Among the factors considered in making such determination were
the history of and the prospects for the industry in which the Company competes,
an assessment of the Company's management, the past and present operations of
the Founding Companies and the Company, the historical results of operations of
the Founding Companies and the Company and the trend of its revenues and
earnings, the prospects for future earnings of the Company, the general
condition of prices of similar securities of generally comparable companies and
other relevant factors. 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 the Offerings at or above the initial public
offering price.
    
 
     The Underwriters have informed the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
   
     Each International Manager represents and agrees that (a) it has not
offered or sold and prior to the expiration of six months from the closing date
of the Offerings, will not offer or sell any shares of Common Stock to persons
in the United Kingdom, except to persons whose ordinary activities involve them
in acquiring, holding, managing or disposing of investments (as principal or
agent) for the purposes of their businesses or otherwise in circumstances which
have not resulted and will not result in an offer to the public in the United
Kingdom within the meaning of the Public Offers of Securities Regulations 1995,
(b) it has complied with and will comply with all applicable provisions of the
Financial Services Act 1986 with respect to anything done by it in relation to
the Common Stock in, from or otherwise involving the United Kingdom, and (c) it
has only issued or passed on and will only issue or pass on to any person in the
United Kingdom any document received by it in connection with the issue or sale
of the Common Stock if that person is of a kind

described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom such document may
otherwise lawfully be issued or passed on.
    
 
   
     No action has been or will be taken in any jurisdiction (except in the
United States) that would permit a public offering of the shares of Common Stock
or the possession, circulation or distribution of this Prospectus or any other
material relating to the Company or the shares of Common Stock in any
jurisdiction where action for that purpose is required. Accordingly, the shares
of Common Stock may not be offered or sold, directly or indirectly, and neither
this Prospectus nor any other offering material or advertisements in connection

hereinafter provided in Section 10 hereof), for whom Merrill Lynch, Donaldson,
Lufkin & Jenrette Securities Corporation, Equitable Securities Corporation and
Sanders Morris Mundy Inc. are acting as representatives (in such capacity, the
"Representatives"), with respect to the issue and sale by the Company and the
purchase by the U.S. Underwriters, acting severally and not jointly, of the
respective numbers of shares of Common Stock, par value $.01 per share, of the
Company ("Common Stock") set forth in said Schedule A, and with respect to the
grant by the Company to the U.S. Underwriters, acting severally and not
jointly, of the option described in Section 2(b) hereof to purchase all or any
part of 840,000 additional shares of Common Stock to cover over-allotments, if

Securities") to be purchased by the U.S. Underwriters and all or any part of
the 840,000 shares of Common Stock subject to the option described in Section

         It is understood that the Company is concurrently entering into an
agreement dated the date hereof (the "International Purchase Agreement")
providing for the offering by the Company of an aggregate of 1,400,000 shares

and, together with the U.S. Option Securities, the "Option Securities").  The
Initial International Securities and the International Option Securities are
hereinafter called the "International Securities".  It is understood that the
Company is not obligated to sell and the U.S. Underwriters are not obligated to
purchase, any Initial U.S. Securities unless all of the Initial International
Securities are contemporaneously purchased by the International Managers.

         The U.S. Underwriters and the International Managers are hereinafter
collectively called the "Underwriters", the Initial U.S. Securities and the
Initial International Securities are hereinafter collectively called the

Agreement of even date herewith (the "Intersyndicate Agreement") providing for
the coordination of certain transactions among the Underwriters under the
direction of Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated (in such capacity, the "Global Coordinator").

public offering of the U.S. Securities as soon as the Representatives deem
advisable after this Agreement has been executed and delivered.

         The Company and the U.S. Underwriters agree that up to 700,000 shares
of the Initial U.S. Securities to be purchased by the U.S. Underwriters (the
"Reserved Securities") shall be reserved for sale by the Underwriters to
certain eligible employees and persons having business relationships with the
Company, as part of the distribution of the Securities by the Underwriters,
subject to the terms of this Agreement, the applicable rules, regulations and
interpretations of the National Association of Securities Dealers, Inc. and all
other applicable laws, rules and regulations.  To the extent that such Reserved
Securities are not orally confirmed for purchase by such eligible employees and
persons having business relationships with the Company by the end of the first
business day after the date of this Agreement, such Reserved Securities may be
offered to the public as part of the public offering contemplated hereby.

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (No. 333-38715) covering the
registration of the Securities under the Securities Act of 1933, as amended
(the "1933 Act"), including the related preliminary prospectus or prospectuses.
Promptly after execution and delivery of this Agreement, the Company will
either (i) prepare and file a prospectus in accordance with the provisions of
Rule 430A ("Rule 430A") of the rules and regulations of the Commission under
the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule
424(b)") of the 1933 Act Regulations or (ii) if the Company has elected to rely
upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term
sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule
424(b).  Two forms of prospectus are to be used in connection with the offering
and sale of the Securities:  one relating to the U.S. Securities (the "Form of
U.S. Prospectus") and one relating to the International Securities (the "Form
of International Prospectus").  The Form of International Prospectus is
identical to the Form of U.S. Prospectus, except for the front cover and back
cover pages and the information under the caption "Underwriting" [and the
inclusion in the Form of International Prospectus of a section under the
caption "Certain United States Tax Considerations for Non-United States
Holders."]  The information included in any such prospectus or in any such Term
Sheet, as the case may be, that was omitted from such registration statement at
the time it became effective but that is deemed to be part of such registration
statement at the time it became effective (a) pursuant to paragraph (b) of Rule
430A is referred to





                                       2
<PAGE>   7
as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is
referred to as "Rule 434 Information."  Each Form of U.S. Prospectus and Form
of International Prospectus used before such registration statement became
effective, and any prospectus that omitted, as applicable, the Rule 430A
Information or the Rule 434 Information, that was used after such effectiveness
and prior to the execution and delivery of this Agreement, is herein called a
"preliminary prospectus."  Such registration statement, including the exhibits
thereto and schedules thereto at the time it became effective and including the
Rule 430A Information and the Rule 434 Information, as applicable, is herein
called the "Registration Statement."  Any registration statement filed pursuant
to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule
462(b) Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement.  The final
Form of U.S. Prospectus and the final Form of International Prospectus in the
forms first furnished to the Underwriters for use in connection with the
offering of the Securities are herein called the "U.S. Prospectus" and the
"International Prospectus," respectively, and collectively, the "Prospectuses."
For purposes of this Agreement, all references to the Registration Statement,
any preliminary prospectus, the U.S. Prospectus, the International Prospectus
or any Term Sheet or any amendment or supplement to any of the foregoing shall
be deemed to include the copy filed with the Commission pursuant to its
Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

         At the Closing Time (defined below), the Company will acquire all of
the outstanding capital stock or other equity interests of each of the
companies listed on Schedule D (each, a "Founding Company" and, collectively,
the "Founding Companies"), in each case pursuant to a stock purchase agreement
(each an "Acquisition Agreement" and, collectively, the "Acquisition
Agreements"), each as described in the Prospectuses under the caption "Certain
Transactions -  Organization of the Company" (collectively, the "Combination").

         SECTION 1.       Representations and Warranties.

         (a)     Representations and Warranties by the Company.  The Company
represents and warrants to each U.S.  Underwriter as of the date hereof, as of
the Closing Time referred to in Section 2(c) hereof, and as of each Date of
Delivery (if any) referred to in Section 2(b), hereof and agrees with each U.S.
Underwriter, as follows:

                 (i)      Compliance with Registration Requirements.  Each of
         the Registration Statement and any Rule 462(b) Registration Statement
         has become effective under the 1933 Act and no stop order suspending
         the effectiveness of the Registration Statement or any Rule 462(b)
         Registration Statement has been issued under the 1933 Act and no
         proceedings for that purpose have been instituted or are pending or,
         to the knowledge of the Company, are contemplated by the Commission,
         and any request on the part of the Commission for additional
         information has been complied with.

                 At the respective times the Registration Statement, any Rule
         462(b) Registration Statement and any post-effective amendments
         thereto became effective and at the Closing Time (and, if any U.S.
         Option Securities are purchased, at the Date of Delivery), the
         Registration Statement, the Rule 462(b) Registration Statement and any
         amendments and supplements thereto complied and will comply in all
         material respects with the requirements of the 1933 Act and the 1933
         Act Regulations and did not and will not contain an untrue statement
         of a material fact or omit to state a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading.  Neither of the Prospectuses nor any amendments or
         supplements thereto, at the time the Prospectuses or any amendments or
         supplements thereto were issued and at the Closing Time (and, if any
         U.S.  Option Securities are purchased, at the Date of Delivery),
         included or will include an untrue statement of a





                                       3
<PAGE>   8
         material fact or omitted or will omit to state a material fact
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.  If Rule 434
         is used, the Company will comply with the requirements of Rule 434 and
         the Prospectuses shall not be "materially different", as such term is
         used in Rule 434, from the prospectuses included in the Registration
         Statement at the time it became effective.  The representations and
         warranties in this subsection shall not apply to statements in or
         omissions from the Registration Statement or the U.S. Prospectus made
         in reliance upon and in conformity with information furnished to the
         Company in writing by any U.S. Underwriter through the Representatives
         expressly for use in the Registration Statement or the U.S.
         Prospectus.

                 Each preliminary prospectus and the prospectuses filed as part
         of the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
         complied when so filed in all material respects with the 1933 Act
         Regulations and each preliminary prospectus and the Prospectuses
         delivered to the Underwriters for use in connection with this offering
         was identical to the electronically transmitted copies thereof filed
         with the Commission pursuant to EDGAR, except to the extent permitted
         by Regulation S-T.

                 (ii)     Independent Accountants.  The accountants who
         certified the financial statements and supporting schedules included
         in the Registration Statement are independent public accountants as
         required by the 1933 Act and the 1933 Act Regulations.

                 (iii)    Financial Statements.  The financial statements
         included in the Registration Statement and the Prospectuses, together
         with the related schedules and notes, present fairly the financial
         position of the Company, the Founding Companies, and their respective
         consolidated subsidiaries at the dates indicated and the statement of
         operations, stockholders' equity and cash flows of the Company, the
         Founding Companies and their consolidated subsidiaries for the periods
         specified; said financial statements have been prepared in conformity
         with generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods involved.  The supporting
         schedules included in the Registration Statement present fairly in
         accordance with GAAP the information required to be stated therein.
         The selected financial data and the summary financial information
         included in the Prospectuses present fairly the information shown
         therein and have been compiled on a basis consistent with that of the
         audited financial statements included in the Registration Statement.
         The pro forma financial statements and the related notes thereto
         included in the Registration Statement and the Prospectuses present
         fairly the information shown therein, have been prepared in accordance
         with the Commission's rules and guidelines with respect to pro forma
         financial statements and have been properly compiled on the bases
         described therein, and the assumptions used in the preparation thereof
         are reasonable and the adjustments used therein are appropriate to
         give effect to the transactions and circumstances referred to therein.

                 (iv)     No Material Adverse Change in Business.  Since the
         respective dates as of which information is given in the Registration
         Statement and the Prospectuses, except as otherwise stated therein,
         (A) there has been no material adverse change in the condition,
         financial or otherwise, or in the earnings, business affairs or
         business prospects of the Company, the Founding Companies and their
         respective subsidiaries considered as one enterprise, whether or not
         arising in the ordinary course of business (a "Material Adverse
         Effect"), (B) there have been no transactions entered into by the
         Company, the Founding Companies or their respective subsidiaries,
         other than those in the ordinary course of business, which are
         material with respect to the Company, the Founding Companies and their
         respective subsidiaries considered as one enterprise, and (C) there
         has been no dividend or





                                       4
<PAGE>   9
         distribution of any kind declared, paid or made by the Company on any
         class of its capital stock or, except as set forth in the
         Prospectuses, by any Founding Company on any class of its capital
         stock.

                 (v)      Good Standing of the Company.  The Company has been
         duly organized and is validly existing as a corporation in good
         standing under the laws of the State of Delaware and has corporate
         power and authority to own, lease and operate its properties and to
         conduct its business as described in the Prospectuses and to enter
         into and perform its obligations under this Agreement.  The Company is
         duly qualified as a foreign corporation to transact business and is in
         good standing in each other jurisdiction in which such qualification
         is required, whether by reason of the ownership or leasing of property
         or the conduct of business, except where the failure so to qualify or
         to be in good standing would not result in a Material Adverse Effect.

                 (vi)     Good Standing of Founding Companies.  The Company has
         no subsidiaries as of the date hereof.  As of the Closing Time, the
         only subsidiaries of the Company will be the Founding Companies and
         their respective subsidiaries.  Each Founding Company or subsidiary
         thereof that is a corporation has been duly organized and is validly
         existing as a corporation in good standing under the laws of the
         jurisdiction of its incorporation, has corporate power and authority
         to own, lease and operate its properties and to conduct its business
         as described in the Prospectuses and is duly qualified as a foreign
         corporation to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct of
         business, except where the failure so to qualify or to be in good
         standing would not result in a Material Adverse Effect.  Except as
         otherwise disclosed in the Registration Statement, all of the issued
         and outstanding capital stock of each Founding Company or subsidiary
         has been duly authorized and validly issued, is fully paid and
         non-assessable, and upon consummation of the Combination, will be
         owned by the Company, directly or through subsidiaries, free and clear
         of any security interest, mortgage, pledge, lien, encumbrance, claim
         or equity.  None of the outstanding shares of capital stock of any
         founding company subsidiary was issued in violation of the preemptive
         or similar rights of any security holder of such subsidiary.  Each
         Founding Company or subsidiary thereof that is a partnership or
         limited liability company has been duly formed and is validly existing
         in good standing under the laws of the jurisdiction of organization,
         has power and authority to own, lease and operate its properties and
         to conduct its business as described in the Prospectuses and is duly
         qualified to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct of
         business, except where the failure so to qualify or to be in good
         standing would not result in a Material Adverse Effect.  Exhibit 21 to
         the Registration Statement sets forth a complete list of the Founding
         Companies and their subsidiaries, except to the extent permitted by
         the rules and regulations of the Commission.

                 (vii)    Capitalization.  As of the Closing Time, the Company
         had authorized capital stock consisting of 100,000,000 shares of
         Common Stock, par value $.01 per share, and 10,000,000 shares of
         Preferred Stock, par value $.01 per share (the "Preferred Stock").
         Prior to the closing of  the transactions contemplated by each of the
         Acquisition Agreements and the issuance of shares of Common Stock as
         contemplated thereby and by the U.S. Purchase Agreement and the
         International Purchase Agreement, the Company had issued and
         outstanding 4,052,311 shares of Common Stock and no shares of
         Preferred Stock; upon  consummation of the Combination and the
         issuance of 12,313,026 shares of Common Stock as contemplated by the
         Acquisition Agreements, (which, together with the 4,052,311 shares of
         Common Stock issued prior to the Combination, are all the shares of
         Common Stock issued or to be issued prior to the issuance and sale of
         the Securities), but without giving effect to the issuance of the
         Securities pursuant to the terms of the U.S. Purchase





                                       5
<PAGE>   10
         Agreement and the International Purchase Agreement, the Company will
         have issued and outstanding 16,365,337 shares of Common Stock and no
         shares of Preferred Stock.   All of such shares of Common Stock have
         been duly authorized and, when issued and delivered to the purchasers
         thereof against payment therefor as provided in the Acquisition
         Agreements, will be validly issued, fully paid and nonassessable.
         None of the outstanding shares of capital stock of the Company was
         issued in violation of the preemptive or other similar rights of any
         security holder of the Company.  Except as described in the
         Prospectuses, there are no outstanding options, warrants or other
         rights calling for the issuance of, and there are no commitments to
         issue any shares of, capital stock of the Company or any security
         convertible into or exchangeable or exercisable for capital stock of
         the Company.

                 (viii)   Authorization of Agreement.  This Agreement and the
         International Purchase Agreement have been duly authorized, executed
         and delivered by the Company.

                 (ix)     Authorization and Description of Securities.  The
         Securities to be purchased by the U.S.  Underwriters and the
         International Managers from the Company have been duly authorized for
         issuance and sale to the U.S. Underwriters pursuant to this Agreement
         and the International Managers pursuant to the International Purchase
         Agreement, respectively, and, when issued and delivered by the Company
         pursuant to this Agreement and the International Purchase Agreement,
         respectively, against payment of the consideration set forth herein
         and the International Purchase Agreement, respectively, will be
         validly issued, fully paid and non-assessable.  The Common Stock
         conforms to all statements relating thereto contained in the
         Prospectuses and such description conforms to the rights set forth in
         the instruments defining the same.  No holder of the Securities will
         be subject to personal liability by reason of being such a holder.
         The issuance of the Securities is not subject to the preemptive or
         other similar rights of any security holder of the Company.

                 (x)      Absence of Defaults and Conflicts.  Neither the
         Company nor any of the Founding Companies or their respective
         subsidiaries is in violation of its charter or by-laws or in default
         in the performance or observance of any obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, lease or other
         agreement or instrument to which the Company, any Founding Company or
         any of their respective subsidiaries is a party or by which it or any
         of them may be bound, or to which any of the property or assets of the
         Company or any subsidiary is subject (collectively, "Agreements and
         Instruments") except for such defaults that would not result in a
         Material Adverse Effect.  The execution, delivery and performance of
         this Agreement, the International Purchase Agreement, and the
         Acquisition Agreements and the consummation of the transactions
         contemplated in this Agreement, the International Purchase Agreement
         and in the Registration Statement (including the issuance and sale of
         the Securities and the use of the proceeds from the sale of the
         Securities as described in the Prospectuses under the caption "Use of
         Proceeds") and compliance by the Company with its obligations under
         this Agreement, the International Purchase Agreement and the
         Acquisition Agreements have been duly authorized by all necessary
         corporate action and do not and will not, whether with or without the
         giving of notice or passage of time or both, conflict with or
         constitute a breach of, or default or Repayment Event (as defined
         below) under, or result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of the Company, any
         Founding Company or any subsidiary pursuant to, the Agreements and
         Instruments (except for such conflicts, breaches or defaults or liens,
         charges or encumbrances that would not result in a Material Adverse
         Effect), nor will such action result in any violation of the
         provisions of the charter or by-laws of the Company, any Founding
         Company or any subsidiary thereof or any applicable law, statute,
         rule, regulation, judgment, order,





                                       6
<PAGE>   11
         writ or decree of any government, government instrumentality or court,
         domestic or foreign, having jurisdiction over the Company, any
         Founding Company or any subsidiary thereof or any of their assets,
         properties or operations.  As used herein, a "Repayment Event" means
         any event or condition which gives the holder of any note, debenture
         or other evidence of indebtedness (or any person acting on such
         holder's behalf) the right to require the repurchase, redemption or
         repayment of all or a portion of such indebtedness by the Company, any
         Founding Company or any subsidiary thereof.

                 (xi)     Absence of Labor Dispute.  No labor dispute with the
         employees of the Company, any Founding Company or any subsidiary
         thereof exists or, to the knowledge of the Company, is imminent, and
         neither the Company nor any Founding Company is aware of any existing
         or imminent labor disturbance by the employees of any of its or any
         subsidiary's principal suppliers, manufacturers, customers or
         contractors, which, in either case, may reasonably be expected to
         result in a Material Adverse Effect.

                 (xii)    Absence of Proceedings.  There is no action, suit,
         proceeding, inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign, now pending, or, to
         the knowledge of the Company, threatened, against or affecting the
         Company, any Founding Company or any subsidiary thereof, which is
         required to be disclosed in the Registration Statement (other than as
         disclosed therein), or which might reasonably be expected to result in
         a Material Adverse Effect, or which might reasonably be expected to
         materially and adversely affect the properties or assets thereof or
         the consummation of the transactions contemplated in this Agreement,
         the International Purchase Agreement or the Acquisition Agreements or
         the performance by the Company of its obligations hereunder or
         thereunder; the aggregate of all pending legal or governmental
         proceedings to which the Company, any Founding Company  or any
         subsidiary thereof is a party or of which any of their respective
         property or assets is the subject which are not described in the
         Registration Statement, including ordinary routine litigation
         incidental to the business, could not reasonably be expected to result
         in a Material Adverse Effect.

                 (xiii)   Accuracy of Exhibits.  There are no contracts or
         documents which are required to be described in the Registration
         Statement or the Prospectuses or to be filed as exhibits thereto which
         have not been so described and filed as required.

                 (xiv)    Possession of Intellectual Property.  The Company,
         the Founding Companies and their subsidiaries own or possess, or can
         acquire on reasonable terms, adequate patents, patent rights,
         licenses, inventions, copyrights, know-how (including trade secrets
         and other unpatented and/or unpatentable proprietary or confidential
         information, systems or procedures), trademarks, service marks, trade
         names or other intellectual property (collectively, "Intellectual
         Property") necessary to carry on the business now operated by them,
         and neither the Company, any Founding Company nor any of its
         subsidiaries has received any notice or is otherwise aware of any
         infringement of or conflict with asserted rights of others with
         respect to any Intellectual Property or of any facts or circumstances
         which would render any Intellectual Property invalid or inadequate to
         protect the interest of the Company, such Founding Company or any of
         its subsidiaries therein, and which infringement or conflict (if the
         subject of any unfavorable decision, ruling or finding) or invalidity
         or inadequacy, singly or in the aggregate, would result in a Material
         Adverse Effect.

                 (xv)     Absence of Further Requirements.  No filing with, or
         authorization, approval, consent, license, order, registration,
         qualification or decree of, any court or governmental authority or
         agency is necessary or required for the performance by the Company of
         its obligations hereunder, in

         connection with the offering, issuance or sale of the Securities under
         this Agreement and the International Purchase Agreement or the
         consummation of the transactions contemplated by this Agreement, the
         International Purchase Agreement or the Acquisition Agreements, except
         such as have been already obtained or as may be required under the
         1933 Act or the 1933 Act Regulations and foreign or state securities
         or blue sky laws.

                 (xvi)    Possession of Licenses and Permits.  The Company,
         each Founding Company and their subsidiaries possess such permits,
         licenses, approvals, consents and other authorizations (collectively,
         "Governmental Licenses") issued by the appropriate federal, state,
         local or foreign regulatory agencies or bodies necessary to conduct
         the business now operated by them.  The Company, each Founding Company
         and their subsidiaries are in compliance with the terms and conditions
         of all such Governmental Licenses, except where the failure so to
         comply would not, singly or in the aggregate, have a Material Adverse
         Effect.  All of the Governmental Licenses are valid and in full force
         and effect, except when the invalidity of such Governmental Licenses
         or the failure of such Governmental Licenses to be in full force and
         effect would not have a Material Adverse Effect.  Neither the Company
         nor any Founding Company or their subsidiaries has received any notice
         of proceedings relating to the revocation or modification of any such
         Governmental Licenses which, singly or in the aggregate, if the
         subject of an unfavorable decision, ruling or finding, would result in
         a Material Adverse Effect.

                 (xvii)   Title to Property.  The Company, each Founding
         Company and their subsidiaries have good and marketable title to all
         real property owned by them and good title to all other properties
         owned by them, in each case, free and clear of all mortgages, pledges,
         liens, security interests, claims, restrictions or encumbrances of any
         kind except such as (a) are described in the Prospectuses or (b) do
         not, singly or in the aggregate, materially affect the value of such
         property and do not interfere with the use made and proposed to be
         made of such property by the Company, the Founding Companies or any of
         their subsidiaries.  All of the leases and subleases material to the
         business of the Company, the Founding Companies or any of their
         subsidiaries, considered as one enterprise, and under which the
         Company, the Founding Company or any of their subsidiaries holds
         properties described in the Prospectuses, are in full force and
         effect, and neither the Company nor any Founding Company or any of
         their subsidiaries has any notice of any material claim of any sort
         that has been asserted by anyone adverse to the rights of the Company,
         such Founding Company or any subsidiary under any of the leases or
         subleases mentioned above, or affecting or questioning the rights of
         the Company, such Founding Company or such subsidiary to the continued
         possession of the leased or subleased premises under any such lease or
         sublease.

                 (xviii)  Compliance with Cuba Act.  The Company has complied
         with, and is and will be in compliance with, the provisions of that
         certain Florida act relating to disclosure of doing business with
         Cuba, codified as Section 517.075 of the Florida statutes, and the
         rules and regulations thereunder (collectively, the "Cuba Act") or is
         exempt therefrom.

                 (xix)    Investment Company Act.  The Company is not, and upon
         the issuance and sale of the Securities as herein contemplated, the
         application of the net proceeds therefrom as described in the
         Prospectuses or consummation of the Combination will not be, an
         "investment company" or an entity "controlled" by an "investment
         company" as such terms are defined in the Investment Company Act of
         1940, as amended (the "1940 Act").

                 (xx)     Environmental Laws.  Except as described in the
         Registration Statement and except as would not, singly or in the
         aggregate, result in a Material Adverse Effect, (A) neither the
         Company, any Founding Company or any subsidiary thereof is in
         violation of any federal, state, local or foreign statute, law, rule,
         regulation, ordinance, code, policy or rule of common law or any
         judicial or administrative interpretation thereof, including any
         judicial or administrative order, consent, decree or judgment,
         relating to pollution or protection of human health, the environment
         (including, without limitation, ambient air, surface water,
         groundwater, land surface or subsurface strata) or wildlife,
         including, without limitation, laws and regulations relating to the
         release or threatened release of chemicals, pollutants, contaminants,
         wastes, toxic substances, hazardous substances, petroleum or petroleum
         products (collectively, "Hazardous Materials") or to the manufacture,
         processing, distribution, use, treatment, storage, disposal, transport
         or handling of Hazardous Materials (collectively, "Environmental
         Laws"), (B) the Company, the Founding Companies and their subsidiaries
         have all permits, authorizations and approvals required under any
         applicable Environmental Laws and are each in compliance with their
         requirements, (C) there are no pending or threatened administrative,
         regulatory or judicial actions, suits, demands, demand letters,
         claims, liens, notices of noncompliance or violation, investigation or
         proceedings relating to any Environmental Law against the Company, any
         Founding Company  or any of their subsidiaries and (D) there are no
         events or circumstances that might reasonably be expected to form the
         basis of an order for clean-up or remediation, or an action, suit or
         proceeding by any private party or governmental body or agency,
         against or affecting the Company, any Founding Company or any of their
         subsidiaries relating to Hazardous Materials or any Environmental
         Laws.

                 (xxi)    Registration Rights.  There are no persons with
         registration rights or other similar rights to have any securities
         registered pursuant to the Registration Statement or otherwise
         registered by the Company under the 1933 Act.

                 (xxii)   Tax Returns.  The Company, each Founding Company and
         each subsidiary have  filed all Federal, state, local and foreign
         income tax returns which have been required to be filed and have paid
         all taxes indicated by said returns and all assessments received by it
         or any of them to the extent that such taxes have become due and are
         not being contested in good faith, except for the filing of those
         returns, and the paying of those taxes, the failure to file or pay,
         respectively, individually or in the aggregate, would not have a
         Material Adverse Effect.  All tax liabilities have been adequately
         provided for in the financial statements of the Company or the
         applicable Founding Company.

                 (xxiii)  Insurance.  The Company and the Founding Companies
         and their subsidiaries carry, or are covered by, insurance in such
         amounts and covering such risks as is reasonably adequate for the
         conduct of their respective businesses and the value of their
         respective properties and as is customary for companies in the
         Company's industry.

                 (xxiv)   ERISA.  The Company and the Founding Companies and
         their subsidiaries are in compliance in all material respects with all
         presently applicable provisions of the Employee Retirement Income
         Security Act of 1974, as amended, including the regulations and
         published interpretations thereunder ("ERISA").

                 (xxv)    Related Party Transactions.  No relationship, direct
         or indirect, exists between or among the Company or any Founding
         Company or subsidiary, on the one hand, and the directors, officers,
         shareholders, customers or suppliers of the Company, such Founding
         Company or its





                                       9
<PAGE>   14
         subsidiaries on the other hand, which is required to be described in
         the Prospectuses which is not so described.

                 (xxvi)   Reserved Shares.  Each of the persons identified by
         the Company to the Underwriters to receive Reserved Shares is a
         citizen of the United States and currently is a resident of one of the
         United States.

                 (xxvii)  Consummation of Combination.   As of the date of this
         Agreement, all conditions to consummation of the transactions
         contemplated by each Acquisition Agreement have been satisfied, with
         the exception of the Closing of the sale of the Securities pursuant to
         this Agreement and the International Purchase Agreement.  There have
         been no amendments or supplements to any of the Acquisition Agreements
         since the original execution thereof on October 21, 1997.  The Company
         has notified the Underwriters of any waiver of any conditions to
         consummation of such Acquisition Agreements.  The Closing (as defined
         in the Acquisition Agreements) with respect to each Acquisition
         Agreement has occurred.  At or prior to the Closing Time, the
         transactions contemplated by each Acquisition Agreement will be
         consummated, with the result that each Founding Company will become a
         wholly-owned direct or indirect subsidiary of the Company as described
         in the Prospectuses.

         (b)     Officer's Certificates.  Any certificate signed by any officer
of the Company or any of its subsidiaries delivered to the Global Coordinator,
the Representatives or to counsel for the U.S. Underwriters shall be deemed a
representation and warranty by the Company to each U.S. Underwriter as to the
matters covered thereby.

         SECTION 2.       Sale and Delivery to U.S. Underwriters; Closing.

         (a)     Initial Securities.  On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein  set
forth, the Company agrees to sell to each U.S. Underwriter, severally and not
jointly, and each U.S. Underwriter, severally and not jointly, agrees to
purchase from the Company, at the price per share set forth in Schedule B, the
number of Initial U.S. Securities set forth in Schedule A opposite the name of
such U.S. Underwriter, plus any additional number of Initial U.S. Securities
which such Underwriter may become obligated to purchase pursuant to the
provisions of Section 10 hereof.

         (b)     Option Securities.  In addition, on the basis of the
representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Company hereby grants an option to the U.S.
Underwriters, severally and not jointly, to purchase up to an additional
840,000 shares of Common Stock at the price per share set forth in Schedule B,
less an amount per share equal to any dividends or distributions declared by
the Company and payable on the Initial U.S. Securities but not payable on the
U.S. Option Securities.  The option hereby granted will expire 30 days after
the date hereof and may be exercised in whole or in part from time to time only
for the purpose of covering over-allotments which may be made in connection
with the offering and distribution of the Initial U.S.  Securities upon notice
by the Global Coordinator to the Company setting forth the number of U.S.
Option Securities as to which the several U.S. Underwriters are then exercising
the option and the time and date of payment and delivery for such U.S. Option
Securities.  Any such time and date of delivery for the U.S. Option Securities
(a "Date of Delivery") shall be determined by the Global Coordinator, but shall
not be later than seven full business days after the exercise of said option,
nor in any event prior to the Closing Time, as hereinafter defined.  If the
option is exercised as to all or any portion of the U.S. Option Securities,
each of the U.S. Underwriters, acting severally and not jointly, will purchase
that proportion of the total number of U.S. Option Securities then being 
purchased which the number of Initial U.S. Securities set forth in Schedule A
opposite the name of such U.S. Underwriter bears to the total number





                                       10
<PAGE>   15
of Initial U.S. Securities, subject in each case to such adjustments as the
Global Coordinator in its discretion shall make to eliminate any sales or
purchases of fractional shares.

         (c)     Payment.  Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of Vinson
& Elkins L.L.P., 1001 Fannin, Houston, Texas, or at such other place as shall
be agreed upon by the Global Coordinator and the Company, at 9:00 A.M. (Eastern
time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern
time) on any given day) business day after the date hereof (unless postponed in
accordance with the provisions of Section 10), or such other time not later
than ten business days after such date as shall be agreed upon by the Global
Coordinator and the Company (such time and date of payment and delivery being
herein called "Closing Time").

         In addition, in the event that any or all of the U.S. Option
Securities are purchased by the U.S. Underwriters, payment of the purchase
price for, and delivery of certificates for, such U.S. Option Securities shall
be made at the above-mentioned offices, or at such other place as shall be
agreed upon by the Global Coordinator and the Company, on each Date of Delivery
as specified in the notice from the Global Coordinator to the Company.

         Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery
to the Representatives for the respective accounts of the U.S. Underwriters of
certificates for the U.S. Securities to be purchased by them.  It is understood
that each U.S. Underwriter has authorized the Representatives, for its account,
to accept delivery of, receipt for, and make payment of the purchase price for,
the Initial U.S. Securities and the U.S. Option Securities, if any, which it
has agreed to purchase.  Merrill Lynch, individually and not as representative
of the U.S. Underwriters, may (but shall not be obligated to) make payment of
the purchase price for the Initial U.S. Securities or the U.S. Option
Securities, if any, to be purchased by any U.S.  Underwriter whose funds have
not been received by the Closing Time or the relevant Date of Delivery, as the
case may be, but such payment shall not relieve such U.S. Underwriter from its
obligations hereunder.

         (d)     Denominations; Registration.  Certificates for the Initial
U.S. Securities and the U.S. Option Securities, if any, shall be in such
denominations and registered in such names as the Representatives may request
in writing at least one full business day before the Closing Time or the
relevant Date of Delivery, as the case may be.  The certificates for the
Initial U.S. Securities and the U.S. Option Securities, if any, will be made
available for examination and packaging by the Representatives in The City of
New York not later than 10:00 A.M. (Eastern time) on the business day prior to
the Closing Time or the relevant Date of Delivery, as the case may be.


         SECTION 3.       Covenants of the Company.  The Company covenants with
each U.S. Underwriter as follows:

         (a)     Compliance with Securities Regulations and Commission
Requests.  The Company, subject to Section 3(b), will comply with the
requirements of Rule 430A or Rule 434, as applicable, and will notify the
Global Coordinator immediately, and confirm the notice in writing, (i) when any
post-effective amendment to the Registration Statement shall become effective,
or any supplement to the Prospectuses or any amended Prospectuses shall have
been filed, (ii) of the receipt of any comments from the Commission, (iii) of
any request by the Commission for any amendment to the Registration Statement
or any amendment or supplement to the Prospectuses or for additional
information, and (iv) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or of any order
preventing or suspending the use





                                       11
<PAGE>   16
of any preliminary prospectus, or of the suspension of the qualification of the
Securities for offering or sale in any jurisdiction, or of the initiation or
threatening of any proceedings for any of such purposes.  The Company will
promptly effect the filings necessary pursuant to Rule 424(b) and will take
such steps as it deems necessary to ascertain promptly whether the form of
prospectus transmitted for filing under Rule 424(b) was received for filing by
the Commission and, in the event that it was not, it will promptly file such
prospectus.  The Company will make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

         (b)     Filing of Amendments.  The Company will give the Global
Coordinator notice of its intention to file or prepare any amendment to the
Registration Statement (including any filing under Rule 462(b)), any Term Sheet
or any amendment, supplement or revision to either the prospectus included in
the Registration Statement at the time it became effective or to the
Prospectuses, will furnish the Global Coordinator with copies of any such
documents a reasonable amount of time prior to such proposed filing or use, as
the case may be, and will not file or use any such document to which the Global
Coordinator or counsel for the U.S. Underwriters shall object.

         (c)     Delivery of Registration Statements.  The Company has
furnished or will deliver to the Representatives and counsel for the U.S.
Underwriters, without charge, signed copies of the Registration Statement as
originally filed and of each amendment thereto (including exhibits filed
therewith or incorporated by reference therein) and signed copies of all
consents and certificates of experts, and will also deliver to the
Representatives, without charge, a conformed copy of the Registration Statement
as originally filed and of each amendment thereto (without exhibits) for each
of the U.S. Underwriters.  The copies of the Registration Statement and each
amendment thereto furnished to the U.S. Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (d)     Delivery of Prospectuses.  The Company has delivered to each
U.S. Underwriter, without charge, as many copies of each preliminary prospectus
as such U.S. Underwriter reasonably requested, and the Company hereby consents
to the use of such copies for purposes permitted by the 1933 Act.  The Company
will furnish to each U.S. Underwriter, without charge, during the period when
the U.S. Prospectus is required to be delivered under the 1933 Act or the
Securities Exchange Act of 1934 (the "1934 Act"), such number of copies of the
U.S. Prospectus (as amended or supplemented) as such U.S. Underwriter may
reasonably request.  The U.S. Prospectus and any amendments or supplements
thereto furnished to the U.S. Underwriters will be identical to the
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (e)     Continued Compliance with Securities Laws.  The Company will
comply with the 1933 Act and the 1933 Act Regulations so as to permit the
completion of the distribution of the Securities as contemplated in this
Agreement, the International Purchase Agreement and in the Prospectuses.  If at
any time when a prospectus is required by the 1933 Act to be delivered in
connection with sales of the Securities, any event shall occur or condition
shall exist as a result of which it is necessary, in the opinion of counsel for
the U.S. Underwriters or for the Company, to amend the Registration Statement
or amend or supplement any Prospectus in order that the Prospectuses will not
include any untrue statements of a material fact or omit to state a material
fact necessary in order to make the statements therein not misleading in the
light of the circumstances existing at the time it is delivered to a purchaser,
or if it shall be necessary, in the opinion of such counsel, at any such time
to amend the Registration Statement or amend or supplement any Prospectus in
order to comply with the requirements of the 1933 Act or the 1933 Act
Regulations, the Company will promptly prepare and file with the Commission,
subject to Section 3(b), such amendment or supplement as 





                                       12
<PAGE>   17
may be necessary to correct such statement or omission or to make the
Registration Statement or the Prospectuses comply with such requirements, and
the Company will furnish to the U.S. Underwriters such number of copies of such
amendment or supplement as the U.S. Underwriters may reasonably request.

         (f)     Blue Sky Qualifications.  The Company will use its best
efforts, in cooperation with the U.S.  Underwriters, to qualify the Securities
for offering and sale under the applicable securities laws of such states and
other jurisdictions (domestic or foreign) as the Global Coordinator may
designate and to maintain such qualifications in effect for a period of not
less than one year from the later of the effective date of the Registration
Statement and any Rule 462(b) Registration Statement; provided, however, that
the Company shall not be obligated to file any general consent to service of
process or to qualify as a foreign corporation or as a dealer in securities in
any jurisdiction in which it is not so qualified or to subject itself to
taxation in respect of doing business in any jurisdiction in which it is not
otherwise so subject.  In each jurisdiction in which the Securities have been
so qualified, the Company will file such statements and reports as may be
required by the laws of such jurisdiction to continue such qualification in
effect for a period of not less than one year from the effective date of the
Registration Statement and any Rule 462(b) Registration Statement.

         (g)     Rule 158.  The Company will timely file such reports pursuant
to the 1934 Act as are necessary in order to make generally available to its
security holders as soon as practicable an earnings statement for the purposes
of, and to provide the benefits contemplated by, the last paragraph of Section
11(a) of the 1933 Act.

         (h)     Use of Proceeds.  The Company will use the net proceeds
received by it from the sale of the Securities in the manner specified in the
Prospectuses under "Use of Proceeds".

         (i)     Listing.  The Company will use its best efforts to effect the
listing of the Common Stock (including the Securities) on the New York Stock
Exchange.

         (j)     Restriction on Sale of Securities.  During a period of 180
days from the date of the Prospectuses, the Company will not, without the prior
written consent of the Global Coordinator, (i) directly or indirectly, offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of any share of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock or
file any registration statement under the 1933 Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Common Stock, or any securities convertible
into or exercisable or exchangeable for Common Stock, whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise.  The foregoing
sentence shall not apply to (A) the Securities to be sold hereunder or under
the International Purchase Agreement, or in connection with the Combination as
described in the Prospectuses, (B) any shares of Common Stock issued or options
to purchase Common Stock granted pursuant to employee benefit plans of the
Company referred to in the Prospectuses or (C) shares of Common Stock issued in
connection with acquisitions by the Company of other businesses, provided that,
(except with respect to shares issued in transactions in which the issuance or
resale of such shares will not be registered under the 1933 Act) the recipients
of such shares agree in writing for the benefit of the U.S. Underwriters not to
take any action described in clauses (i) or (ii) above with respect to such
shares until the expiration of 180 days from the date of the Prospectuses.





                                       13
<PAGE>   18
         (k)     Reporting Requirements.  The Company, during the period when
the Prospectuses are required to be delivered under the 1933 Act or the 1934
Act, will file all documents required to be filed with the Commission pursuant
to the 1934 Act within the time periods required by the 1934 Act and the rules
and regulations of the Commission thereunder.

         (l)     Compliance with NASD Rules.  The Company hereby agrees that it
will ensure that the Reserved Securities will be restricted as required by the
National Association of Securities Dealers, Inc. (the "NASD") or the NASD rules
from sale, transfer, assignment, pledge or hypothecation for a period of three
months following the date of this Agreement.  The Underwriters will notify the
Company as to which persons will need to be so restricted.  At the request of
the Underwriters, the Company will direct the transfer agent to place a stop
transfer restriction upon such securities for such period of time.  Should the
Company release, or seek to release, from such restrictions any of the Reserved
Securities, the Company agrees to reimburse the Underwriters for any reasonable
expenses (including, without limitation, legal expenses) they incur in
connection with such release.

         (m)     Compliance with Rule 463.  The Company will file with the
Commission such reports on Form SR as may be required pursuant to Rule 463 of
the 1933 Act Regulations.

Agreement, including (i) the preparation, printing and filing of the
Registration Statement (including financial statements and exhibits) as
originally filed and of each amendment thereto, (ii) the preparation, printing
and delivery to the Underwriters of this Agreement, any Agreement among
Underwriters and such other documents as may be required in connection with the
offering, purchase, sale, issuance or delivery of the Securities, (iii) the
preparation, issuance and delivery of the certificates for the Securities to
the Underwriters, including any stock or other transfer taxes and any stamp or
other duties payable upon the sale, issuance or delivery of the Securities to
the Underwriters and the transfer of the Securities between the U.S.
Underwriters and the International Managers, (iv) the fees and disbursements of
the Company's counsel, accountants and other advisors, (v) the qualification of
the Securities under securities laws in accordance with the provisions of
Section 3(f) hereof, including filing fees and the reasonable fees and
disbursements of counsel for the Underwriters in connection therewith and in

contained in Section 1 hereof or in certificates of any officer of the Company
delivered pursuant to the provisions hereof, to the performance by the Company
of its covenants and other obligations hereunder, and to the following further
conditions:

         (a)     Effectiveness of Registration Statement.  The Registration

the Registration Statement shall have been issued under the 1933 Act or
proceedings therefor initiated or threatened by the Commission, and any request
on the part of the Commission for additional information shall have been
complied with to the reasonable satisfaction of counsel to the U.S.
Underwriters.  A prospectus containing the Rule 430A Information shall have

post-effective amendment providing such information shall have been filed and
declared effective in accordance with the requirements of Rule 430A) or, if the
Company has elected to rely upon Rule 434, a Term Sheet shall have been filed
with the Commission in accordance with Rule 424(b).

         (b)     Opinions of Counsel for the Company and the Founding
Companies.  At Closing Time, the Representatives shall have received (i) the

inclusive, (xii), (xiv) (solely as to the information in the Prospectus under
"Description of Capital Stock--Common Stock") and the penultimate paragraph of
Exhibit A-1 hereto.  In giving such opinion such counsel may rely, as to all
matters governed by the laws of jurisdictions other than the law of the State
of New York, the federal law of the United States and the General Corporation
Law of the State of Delaware, upon the opinions of counsel satisfactory to the
Representatives.  Such counsel may also state that, insofar as such opinion
involves factual matters, they have relied, to the extent they deem proper,
upon certificates of officers of the Company and its subsidiaries and
certificates of public officials.

         (d)     Officers' Certificate.  At Closing Time, there shall not have
been, since the date hereof or since the respective dates as of which
information is given in the Prospectuses, any material adverse change in the

considered as one enterprise, whether or not arising in the ordinary course of
business, and the Representatives shall have received a certificate of the
President or a Vice President of the Company and of the chief financial or
chief accounting officer of the Company, dated as of Closing Time, to the

<PAGE>   20
order suspending the effectiveness of the Registration Statement has been
issued and no proceedings for that purpose have been instituted or are pending
or are contemplated by the Commission.

         (e)     Accountant's Comfort Letter.  At the time of the execution of
this Agreement, the Representatives shall have received from Arthur Andersen
LLP a letter dated such date, in form and substance satisfactory to the
Representatives, together with signed or reproduced copies of such letter for
each of the other U.S. Underwriters containing statements and information of
the type ordinarily included in accountants' "comfort letters" to underwriters
with respect to the financial statements and certain financial information
contained in the Registration Statement and the Prospectuses.

         (f)     Bring-down Comfort Letter.  At Closing Time, the
Representatives shall have received from Arthur Andersen LLP a letter, dated as
of Closing Time, to the effect that they reaffirm the statements made in the
letter furnished pursuant to subsection (e) of this Section, except that the
specified date referred to shall be a date not more than three business days

have been approved for listing on the New York Stock Exchange, subject only to
official notice of issuance.

         (h)     No Objection.  The NASD has confirmed that it has not raised
any objection with respect to the fairness and reasonableness of the
underwriting terms and arrangements contemplated hereby.

Acquisition Agreement shall have been consummated, with the result that each
Founding Company is a wholly-owned direct or indirect subsidiary of the Company
as described in the Prospectuses.

         (k)     Purchase of Initial International Securities.
Contemporaneously with the purchase by the U.S.  Underwriters of the Initial
U.S. Securities under this Agreement, the International Managers shall have

Agreement.

         (l)     Conditions to Purchase of U.S. Option Securities.  In the
event that the U.S. Underwriters exercise their option provided in Section 2(b)
hereof to purchase all or any portion of the U.S. Option Securities, the
representations and warranties of the Company contained herein and the
statements in any certificates furnished by the Company or any subsidiary of
the Company hereunder shall be true and correct as of each Date of Delivery
and, at the relevant Date of Delivery, the Representatives shall have received:

                 (i)      Officers' Certificate.  A certificate, dated such
         Date of Delivery, of the President or a Vice President of the Company
         and of the chief financial or chief accounting officer of the Company
         confirming that the certificate delivered at the Closing Time pursuant
         to Section 5(d) hereof remains true and correct as of such Date of
         Delivery.

         purchased on such Date of Delivery and otherwise to the same effect as
         the opinions required by Sections 5(b)(i) and (ii) hereof.





                                       16
<PAGE>   21
                 (iii)    Opinion of Counsel for U.S. Underwriters.  The
         favorable opinion of Vinson & Elkins L.L.P., counsel for the U.S.
         Underwriters, dated such Date of Delivery, relating to the U.S. Option
         Securities to be purchased on such Date of Delivery and otherwise to
         the same effect as the opinion required by Section 5(c) hereof.

                 (iv)     Bring-down Comfort Letter.  A letter from Arthur
         Andersen LLP, in form and substance satisfactory to the
         Representatives and dated such Date of Delivery, substantially in the
         same form and substance as the letter furnished to the Representatives
         pursuant to Section 5(f) hereof, except that the "specified date" in
         the letter furnished pursuant to this paragraph shall be a date not
         more than five days prior to such Date of Delivery.

         (m)     Additional Documents.  At Closing Time and at each Date of
Delivery, counsel for the U.S. Underwriters shall have been furnished with such
documents and opinions as they may require for the purpose of enabling them to
pass upon the issuance and sale of the Securities as herein contemplated, or in
order to evidence the accuracy of any of the representations or warranties, or
the fulfillment of any of the conditions, herein contained; and all proceedings
taken by the Company in connection with the issuance and sale of the Securities
as herein contemplated shall be satisfactory in form and substance to the
Representatives and counsel for the U.S. Underwriters.

         (n)     Termination of Agreement.  If any condition specified in this
Section shall not have been fulfilled when and as required to be fulfilled,
this Agreement, or, in the case of any condition to the purchase of U.S. Option
Securities on a Date of Delivery which is after the Closing Time, the
obligations of the several U.S. Underwriters to purchase the relevant Option
Securities, may be terminated by the Representatives by notice to the Company
at any time at or prior to Closing Time or such Date of Delivery, as the case
may be, and such  termination shall be without liability of any party to any
other party except as provided in Section 4 and except that Sections 1, 6, 7
and 8 shall survive any such termination and remain in full force and effect.

SECTION 6.       Indemnification.

         (a)     Indemnification of U.S. Underwriters. The Company agrees to
indemnify and hold harmless each U.S.  Underwriter and each person, if any, who
controls any U.S. Underwriter within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act as follows:

                 (i)      against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement (or any amendment thereto), including the
         Rule 430A Information and the Rule 434 Information, if applicable, or
         the omission or alleged omission therefrom of a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact included in any preliminary prospectus or
         the Prospectuses (or any amendment or supplement thereto), or the
         omission or alleged omission therefrom of a material fact necessary in
         order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                 (ii)     against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, to the extent of the aggregate
         amount paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement





                                       17
<PAGE>   22
         or omission; provided that (subject to Section 6(d) below) any such
         settlement is effected with the written consent of the Company; and

                 (iii)    against any and all expense whatsoever, as incurred
         (including the fees and disbursements of counsel chosen by Merrill
         Lynch), reasonably incurred in investigating, preparing or defending
         against any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
U.S. Underwriter through the Representatives expressly for use in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any preliminary
prospectus or the U.S. Prospectus (or any amendment or supplement thereto).

         (b)     Indemnification of Company, Directors and Officers.  Each U.S.
Underwriter severally agrees to indemnify and hold harmless the Company, its
directors, each of its officers who signed the Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 15 of
the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection
(a) of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), including the Rule 430A Information and
the Rule 434 Information, if applicable, or any preliminary U.S. prospectus or
the U.S. Prospectus (or any amendment or supplement thereto) in reliance upon
and in conformity with written information furnished to the Company by such
U.S. Underwriter through the Representatives expressly for use in the
Registration Statement (or any amendment thereto) or such preliminary
prospectus or the U.S. Prospectus (or any amendment or supplement thereto).

         (c)     Actions against Parties; Notification.  Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it
is not materially prejudiced as a result thereof and in any event shall not
relieve it from any liability which it may have otherwise than on account of
this indemnity agreement.  In the case of parties indemnified pursuant to
Section 6(a) above, counsel to the indemnified parties shall be selected by
Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b)
above, counsel to the indemnified parties shall be selected by the Company.  An
indemnifying party may participate at its own expense in the defense of any
such action; provided, however, that counsel to the indemnifying party shall
not (except with the consent of the indemnified party) also be counsel to the
indemnified party.  In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.  No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever
in respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each





                                       18
<PAGE>   23
indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.

         (d)     Settlement without Consent if Failure to Reimburse.  If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 6(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

         (e)     Indemnification for Reserved Securities.  In connection with
the offer and sale of the Reserved Securities, the Company agrees, promptly
upon a request in writing to indemnify and hold harmless the Underwriters from
and against any and all losses, liabilities, claims, damages and expenses
incurred by them as a result of the failure of any person or entity to whom
Reserved Securities are offered to pay for and accept delivery of Reserved
Securities which, by the end of the first business day following the date of
this Agreement, were subject to a properly confirmed agreement to purchase.

         SECTION 7.       Contribution.  If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the U.S.  Underwriters on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause (i) is not permitted by applicable law, in such proportion
as is appropriate to reflect not only the relative benefits referred to in
clause (i) above but also the relative fault of the Company on the one hand and
of the U.S. Underwriters on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

         The relative benefits received by the Company on the one hand and the
U.S. Underwriters on the other hand in connection with the offering of the U.S.
Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the U.S.
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total underwriting discount received by the U.S.
Underwriters, in each case as set forth on the cover of the U.S. Prospectus,
or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to
the aggregate initial public offering price of the U.S. Securities as set forth
on such cover.

         The relative fault of the Company on the one hand and the U.S.
Underwriters on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company or by the U.S.  Underwriters and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

         The Company and the U.S. Underwriters agree that it would not be just
and equitable if contribution pursuant to this Section 7 were determined by pro
rata allocation (even if the U.S. Underwriters were treated





                                       19
<PAGE>   24
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 7.  The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
7 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 7, no U.S. Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the U.S. Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such U.S. Underwriter has otherwise been required to pay by reason of any such
untrue or alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls a
U.S. Underwriter within the meaning of Section 15 of the 1933 Act or Section 20
of the 1934 Act shall have the same rights to contribution as such U.S.
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act shall have the same rights to contribution as the Company.  The U.S.
Underwriters' respective obligations to contribute pursuant to this Section 7
are several in proportion to the number of Initial U.S. Securities set forth
opposite their respective names in Schedule A hereto and not joint.

         SECTION 8.       Representations, Warranties and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its
subsidiaries submitted pursuant hereto, shall remain operative and in full
force and effect, regardless of any investigation made by or on behalf of any
U.S. Underwriter or controlling person, or by or on behalf of the Company, and
shall survive delivery of the Securities to the U.S. Underwriters.

         SECTION 9.       Termination of Agreement.

         (a)     Termination; General.  The Representatives may terminate this
Agreement, by notice to the Company, at any time at or prior to Closing Time
(i) if there has been, since the time of execution of this Agreement or since
the respective dates as of which information is given in the U.S. Prospectus,
any material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Company, the Founding
Companies and their subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there has occurred any
material adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or
economic conditions, in each case the effect of which is such as to make it, in
the judgment of the Representatives, impracticable to market the Securities or
to enforce contracts for the sale of the Securities, or (iii) if trading in any
securities of the Company has been suspended or materially limited by the
Commission or the New York Stock Exchange, or if trading generally on the
American Stock Exchange or the New York Stock Exchange or in the Nasdaq
National Market has been suspended or materially limited, or minimum or maximum
prices for trading have





                                       20
<PAGE>   25
been fixed, or maximum ranges for prices have been required, by
any of said exchanges or by such system or by order of the Commission, the
National Association of Securities Dealers, Inc. or any other governmental
authority, or (iv) if a banking moratorium has been declared by either Federal
or New York authorities.

         (b)     Liabilities.  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that
Sections 1, 6, 7 and 8 shall survive such termination and remain in full force
and effect.

         SECTION 10.  Default by One or More of the U.S. Underwriters.  If one
or more of the U.S. Underwriters shall fail at Closing Time or a Date of
Delivery to purchase the Securities which it or they are obligated to purchase
under this Agreement (the "Defaulted Securities"), the Representatives shall
have the right, within 24 hours thereafter, to make arrangements for one or
more of the non-defaulting U.S. Underwriters, or any other underwriters, to
purchase all, but not less than all, of the Defaulted Securities in such
amounts as may be agreed upon and upon the terms herein set forth; if, however,
the Representatives shall not have completed such arrangements within such
24-hour period, then:

        (a)     if the number of Defaulted Securities does not exceed 10% of
the number of U.S. Securities to be purchased on such date, each of the
non-defaulting U.S. Underwriters shall be obligated, severally and not jointly,
to purchase the full amount thereof in the proportions that their respective
underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting U.S. Underwriters, or

         (b)     if the number of Defaulted Securities exceeds 10% of the
number of U.S. Securities to be purchased on such date, this Agreement or, with
respect to any Date of Delivery which occurs after the Closing Time, the
obligation of the U.S. Underwriters to purchase and of the Company to sell the
Option Securities to be purchased and sold on such Date of Delivery shall
terminate without liability on the part of any non-defaulting U.S. Underwriter.

         No action taken pursuant to this Section shall relieve any defaulting
U.S. Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a
termination of this Agreement or, in the case of a Date of Delivery which is
after the Closing Time, which does not result in a termination of the
obligation of the U.S.  Underwriters to purchase and the Company to sell the
relevant U.S. Option Securities, as the case may be, either the Representatives
or the Company shall have the right to postpone Closing Time or the relevant
Date of Delivery, as the case may be, for a period not exceeding seven days in
order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements.  As used herein, the term
"U.S. Underwriter" includes any person substituted for a U.S. Underwriter under
this Section 10.

         SECTION 11.  Notices.  All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the U.S.
Underwriters shall be directed to the Representatives at North Tower, World

                      FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                SECTION 5(b)(i)


         (i)     The Company has been duly incorporated and is validly existing
as a corporation in good standing under the laws of the State of Delaware.

         (ii)    The Company has corporate power and authority to own, lease
and operate its properties and to conduct its business as described in the
Prospectuses and to enter into and perform its obligations under the U.S.
Purchase Agreement and the International Purchase Agreement.

         (iii)   The Company is duly qualified as a foreign corporation to
transact business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect.

         (iv)    As of the Closing Time, the Company had authorized capital
stock consisting of 100,000,000 shares of Common Stock, par value $.01 per
share, and 10,000,000 shares of Preferred Stock, par  value $.01 per share (the
"Preferred Stock").  Prior to the closing of  the transactions contemplated by
each of the Acquisition Agreements and the issuance of shares of Common Stock
as contemplated thereby and by the U.S. Purchase Agreement and the
International Purchase Agreement, the Company had issued and outstanding
4,052,311 shares of Common Stock and no shares of Preferred Stock; upon
consummation of the Combination and the issuance of 12,313,026 shares of Common
Stock as contemplated by the Acquisition Agreements, (which, together with the
4,052,311 shares of Common Stock issued prior to the Combination, are all the
shares of Common Stock issued or to be issued prior to the issuance and sale of
the Securities), but without giving  effect to the issuance of the Securities
pursuant to the terms of the U.S. Purchase Agreement and the International
Purchase Agreement, the Company will have issued and outstanding 16,365,337
shares of Common Stock and no shares of Preferred Stock.  All of such shares
of Common Stock have been duly authorized and, when issued and delivered to the
purchasers thereof against payment therefor as provided in the Acquisition
Agreements, will be validly issued, fully paid and nonassessable.  None of the
outstanding shares of capital stock of the Company was issued in violation of
the preemptive or  other similar rights of any security holder of the Company.
Except as described in the Prospectuses, to our knowledge there are no
outstanding options, warrants or other rights calling for the issuance of, and
there are no commitments to issue any shares of, capital stock of the Company
or any security convertible into or exchangeable or exercisable for capital
stock of the Company.

         (v)     The Securities to be purchased by the U.S. Underwriters and
the International Managers from the Company have been duly authorized for
issuance and sale to the Underwriters pursuant to the U.S. Purchase Agreement
and the International Purchase Agreement, respectively, and, when issued and
delivered by the Company pursuant to the U.S. Purchase Agreement and the
International Purchase Agreement, respectively, against payment of the
consideration set forth in the U.S. Purchase Agreement and the International
Purchase Agreement, will be validly issued and fully paid and non-assessable
and no holder of the Securities is or will be subject to personal liability by
reason of being such a holder.





                                      A1-1
<PAGE>   33
         (vi)    The issuance of the Securities is not subject to the
preemptive or other similar rights of any security holder of the Company.

         (vii)   Each Acquisition Agreement has been duly and validly
authorized, executed and delivered by the Company and constitutes the valid and
binding obligation of each of the Company enforceable in accordance with its
terms, except as may be limited by bankruptcy, insolvency and other laws
affecting creditors' rights generally, or as may be modified by a court of
equity.

         (viii)  The transactions contemplated by each Acquisition Agreement
have been consummated as described in the Prospectuses.  As a result of the
Combination, all of the issued and outstanding capital stock or other equity
interest of each Founding Company and their subsidiaries is owned by the
Company, directly or through subsidiaries, free and clear of any security
interest, mortgage, pledge, lien, encumbrance, claim, shareholders agreement,
or voting trust, and no options, warrants or other rights to purchase,
agreements, or other obligations to issue or other rights to convert any other
obligations into shares of capital stock or ownership interests in any Founding
Company or any subsidiary thereof are outstanding.

         (ix)    The U.S. Purchase Agreement and the International Purchase
Agreement have been duly authorized, executed and delivered by the Company.

         (x)     The Registration Statement, including any Rule 462(b)
Registration Statement, has been declared effective under the 1933 Act; any
required filing of the Prospectuses pursuant to Rule 424(b) has been made in
the manner and within the time period required by Rule 424(b); and, to the best
of our knowledge, no stop order suspending the effectiveness of the
Registration Statement or any Rule 462(b) Registration Statement has been
issued under the 1933 Act and no proceedings for that purpose have been
instituted or are pending or threatened by the Commission.

         (xi)    The Registration Statement including any Rule 462(b)
Registration Statement and the Rule 430A Information, as applicable, the
Prospectuses and each amendment or supplement to the Registration Statement and
the Prospectuses as of their respective effective or issue dates (other than
the financial statements and supporting schedules included therein or omitted
therefrom, as to which we need express no opinion) complied as to form in all
material respects with the requirements of the 1933 Act and the 1933 Act
Regulations.

         (xii)   The form of certificate used to evidence the Common Stock
complies in all material respects with all applicable statutory requirements,
with any applicable requirements of the charter and by-laws of the Company and
the requirements of the New York Stock Exchange.

         (xiii)  To the best of our knowledge, there is not pending or
threatened any action, suit, proceeding, inquiry or investigation, to which the
Company or any Founding Company is a party, or to which the property of the
Company or any Founding Company is subject, before or brought by any court or
governmental agency or body, domestic or foreign, which might reasonably be
expected to result in a Material Adverse Effect, or which might reasonably be
expected to materially and adversely affect the properties or assets thereof or
the consummation of the transactions contemplated in the U.S. Purchase
Agreement, the International Purchase Agreement or the Acquisition Agreements
or the performance by the Company of its obligations thereunder.

         (xiv)   The information in the Prospectuses under the headings
"Management -- Employment Agreements," "--1997 Stock Plan," "--1997 Directors
Stock Plan;" "Certain Transactions;" "Description of





                                      A1-2
<PAGE>   34
Capital Stock," "Certain United States Tax Considerations for Non-United States
Holders" and "Shares Eligible For Future Sale," and in the Registration
Statement under Item 14, to the extent that it constitutes matters of law,
summaries of legal matters, the Company's charter and bylaws or legal
conclusions, has been reviewed by us  and is correct in all material respects.

         (xv)    To the best of our knowledge, there are no statutes or
regulations that are required to be described in the Prospectuses that are not
described as required.

         (xvi)   All descriptions in the Prospectuses of contracts and other
documents to which the Company or any Founding Company is a party are accurate
in all material respects; to the best of our knowledge, there are no
franchises, contracts, indentures, mortgages, loan agreements, notes, leases or
other instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

         (xvii)  The Company is not in violation of its charter, by-laws or
other governing documents and, to our best knowledge, no default by the Company
exists in the due performance or observance of any material obligation,
agreement, covenant or condition contained in any contract, indenture,
mortgage, loan agreement, note, lease or other agreement or instrument that is
described or referred to in the Registration Statement or the Prospectuses or
filed or incorporated by reference as an exhibit to the Registration Statement.

         (xviii) No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign (other than under the 1933 Act and the
1933 Act Regulations, which have been obtained, or as may be required under the
securities or blue sky laws of the various states, as to which we express no
opinion) is necessary or required in connection with the due authorization,
execution and delivery of the U.S. Purchase Agreement and the International
Purchase Agreement or for the offering, issuance, sale or delivery of the
Securities.

         (xix)   No registration under the Act and no filing with, consent,
approval, authorization, order, registration or qualification of or with any
court or governmental agency or body is required for the issuance of the
Company Common Stock to the stockholders of each Founding Company pursuant to
the Acquisition Agreements or the consummation of the other transactions
contemplated by the Acquisition Agreements, except such filings, consents,
approvals, authorizations, registrations or qualifications as have been
obtained or made.

         (xx)    The execution, delivery and performance of the U.S. Purchase
Agreement and the International Purchase Agreement and the consummation of the
transactions contemplated in the U.S. Purchase Agreement, the International
Purchase Agreement and in the Registration Statement (including the issuance
and sale of the Securities, and the use of the proceeds from the sale of the
Securities as described in the Prospectuses under the caption "Use Of
Proceeds") and compliance by the Company with its obligations under the U.S.
Purchase Agreement and the International Purchase Agreement do not and will
not, whether with or without the giving of notice or lapse of time or both,
conflict with or constitute a breach of, or default or Repayment Event (as
defined in Section 1(a)(x) of the Purchase Agreements) under or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Company or any Founding Company pursuant to any contract,
indenture, mortgage, deed of trust, loan or credit agreement, note, lease or
any other agreement or instrument, known to us, to which the Company or any
Founding Company is a party or by which it or any of them may be bound, or to
which any of the property





                                      A1-3
<PAGE>   35
or assets of the Company or any Founding Company is subject (except for such
conflicts, breaches or defaults or liens, charges or encumbrances that would
not have a Material Adverse Effect), nor will such action result in any
violation of the provisions of the charter, by-laws or other governing
documents of the Company or any Founding Company, or any applicable law,
statute, rule, regulation, judgment, order, writ or decree, known to us, of any
government, government instrumentality or court, domestic or foreign, having
jurisdiction over the Company or any Founding Company or any of their
respective properties, assets or operations.

         (xxi)   To the best of our knowledge, except as set forth in the
Prospectuses, there are no persons with registration rights or other similar
rights to have any securities registered pursuant to the Registration Statement
or otherwise registered by the Company under the 1933 Act.

         (xxii)  The Company is not, and will not be after consummation of the
Combination or application of the proceeds of the offering of the Securities as
set forth in the Prospectuses, an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the 1940
Act.

         Nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the Rule 430A
Information, (except for financial statements and schedules and other financial
data included therein or omitted therefrom, as to which we make no statement),
at the time such Registration Statement or any such amendment became effective,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading or that the Prospectuses or any amendment or supplement thereto
(except for financial statements and schedules and other financial data
included therein or omitted therefrom, as to which we make no statement), at
the time the Prospectuses were issued, at the time any such amended or
supplemented prospectus was issued or at the Closing Time, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

         In rendering opinions set forth above with respect to matters
concerning the Founding Companies, such counsel may rely (A) as to matters
involving the application of the laws of the jurisdiction of incorporation or
organization of each Founding Company, upon the opinion of counsel to each
Founding Company (which opinion shall be dated and furnished to the U.S.
Representatives at the Closing Time, shall be satisfactory in form and
substance to counsel for the U.S.  Underwriters and shall expressly state that
the U.S. Underwriters may rely on such opinion as if it were addressed to
them), provided that such counsel shall state in their opinion that they
believe that they and the U.S. Underwriters are justified in relying upon such
opinion, and (B), as to matters of fact (but not as to legal conclusions), to
the extent they deem proper, on certificates of responsible officers of the
Company and public officials.  Such opinion shall not state that it is to be
governed or qualified by, or that it is otherwise subject to, any treatise,
written policy or other document relating to legal opinions, including, without
limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

                       FORM OF OPINION OF COUNSEL OF EACH
                                FOUNDING COMPANY
                  TO BE DELIVERED PURSUANT TO SECTION 5(b)(ii)

         (i)     Such Founding Company or any subsidiary thereof  that is a
corporation has been duly incorporated and is validly existing as a corporation
in good standing under the laws of the jurisdiction of its incorporation, has
corporate power and authority to own, lease and operate its properties and to
conduct its business as described in the Prospectuses and is duly qualified as
a foreign corporation to transact business and is in good standing in each
jurisdiction in which such qualification is required, whether by reason of the
ownership or leasing of property or the conduct of business, except where the
failure so to qualify or to be in good standing would not result in a Material
Adverse Effect.  None of the outstanding shares of capital stock of such
Founding Company or any subsidiary thereof was issued in violation of the
preemptive or similar rights of any security holder of such Founding Company or
subsidiary.  All of the issued and outstanding capital stock of such Founding
Company or any subsidiary thereof has been duly authorized and validly issued,
and is fully paid and non-assessable.   Such Founding Company or subsidiary
thereof that is a partnership or limited liability company has been duly formed
and is validly existing in good standing under the laws of the jurisdiction of
organization, has power and authority to own, lease and operate its properties
and to conduct its business as described in the Prospectuses and is duly
qualified to transact business and is in good standing in each jurisdiction in
which such qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except where the failure so to
qualify or to be in good standing would not result in a Material Adverse
Effect.

         (ii)    Each Acquisition Agreement has been duly and validly
authorized by such Founding Company and its shareholders and constitutes the
valid and binding obligation of such Founding Company and its shareholders
enforceable in accordance with its terms, except as may be limited by
bankruptcy, insolvency and other laws affecting creditors' rights generally, or
as may be modified by a court of equity.

         (iii)   Neither such Founding Company nor any subsidiary is in
violation of its charter, by-laws or other governing documents and, to the best
of our knowledge, no default by such Founding Company or any of its
subsidiaries exists in the due performance or observance of any material
obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described or referred to in the Registration Statement or
the Prospectuses or filed or incorporated by reference as an exhibit to the
Registration Statement.

         In rendering opinions set forth above, such counsel may rely as to
matters of fact (but not as to legal conclusions), to the extent they deem
proper, on certificates of responsible officers of the Founding Company and
public officials.  Such opinion shall not state that it is to be governed or
qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation,
the Legal Opinion Accord of the ABA Section of Business Law (1991).

Ladies and Gentlemen:

         Integrated Electrical Services, Inc., a Delaware corporation (the
"Company"), confirms its agreement with Merrill Lynch International ("Merrill
Lynch") and each of the other international underwriters named in Schedule A
hereto (collectively, the "International Managers", which term shall also
include any underwriter substituted as hereinafter provided in Section 10
hereof), for whom Merrill Lynch, Donaldson, Lufkin & Jenrette Securities
Corporation, Equitable Securities Corporation and Sanders Morris Mundy Inc. are
acting as representatives (in such capacity, the "Lead Managers"), with respect
to the issue and sale by the Company and the purchase by the International
Managers, acting severally and not jointly, of the respective numbers of shares
of Common Stock, par value $.01 per share, of the Company ("Common Stock") set
forth in said Schedule A, and with respect to the grant by the Company to the
International Managers, acting severally and not jointly, of the option
described in Section 2(b) hereof to purchase all or any part of 210,000
additional shares of Common Stock to cover over-allotments, if any.  The
aforesaid 1,400,000 shares of Common Stock (the "Initial International
Securities") to be purchased by the International Managers and all or any part
of the 210,000 shares of Common Stock subject to the option described in
Section 2(b) hereof (the "International Option Securities") are hereinafter
called, collectively, the "International Securities".

         It is understood that the Company is concurrently entering into an
agreement dated the date hereof (the "U.S.  Purchase Agreement") providing for
the offering by the Company of an aggregate of 5,600,000 shares of Common Stock
(the "Initial U.S. Securities") through arrangements with certain underwriters
in the United States and Canada (the "U.S.  Underwriters") for which Merrill
Lynch, Pierce, Fenner & Smith Incorporated, Donaldson, Lufkin & Jenrette
Securities Corporation, Equitable Securities Corporation and Sanders Morris
Mundy Inc. are acting as representatives (the "U.S.  Representatives") and the
grant by the Company to the U.S. Underwriters, acting severally and not
jointly, of an option to purchase all or any part of the U.S. Underwriters' pro
rata portion of up to 840,000 additional shares of Common Stock solely to cover
overallotments, if any (the "U.S. Option Securities" and, together with the
International Option Securities, the "Option Securities").  The Initial U.S.
Securities and the U.S. Option Securities are hereinafter called the "U.S.
Securities".  It is
<PAGE>   5
understood that the Company is not obligated to sell and the International
Managers are not obligated to purchase, any Initial International Securities
unless all of the Initial U.S. Securities are contemporaneously purchased by
the U.S.  Underwriters.

         The International Managers and the U.S. Underwriters are hereinafter
collectively called the "Underwriters", the Initial International Securities
and the Initial U.S. Securities are hereinafter collectively called the
"Initial Securities", and the International Securities, and the U.S. Securities
are hereinafter collectively called the "Securities".

         The Underwriters will concurrently enter into an Intersyndicate
Agreement of even date herewith (the "Intersyndicate Agreement") providing for
the coordination of certain transactions among the Underwriters under the
direction of Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated (in such capacity, the "Global Coordinator").

         The Company understands that the International Managers propose to
make a public offering of the International Securities as soon as the Lead
Managers deem advisable after this Agreement has been executed and delivered.

         The Company and the International Managers agree that up to 700,000
shares of the Initial U.S. Securities to be purchased by the U.S. Underwriters
(the "Reserved Securities") shall be reserved for sale by the Underwriters to
certain eligible employees and persons having business relationships with the
Company, as part of the distribution of the Securities by the Underwriters,
subject to the terms of this Agreement, the applicable rules, regulations and
interpretations of the National Association of Securities Dealers, Inc. and all
other applicable laws, rules and regulations.  To the extent that such Reserved
Securities are not orally confirmed for purchase by such eligible employees and
persons having business relationships with the Company by the end of the first
business day after the date of this Agreement, such Reserved Securities may be
offered to the public as part of the public offering contemplated hereby.

         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (No. 333-38715) covering the
registration of the Securities under the Securities Act of 1933, as amended
(the "1933 Act"), including the related preliminary prospectus or prospectuses.
Promptly after execution and delivery of this Agreement, the Company will
either (i) prepare and file a prospectus in accordance with the provisions of
Rule 430A ("Rule 430A") of the rules and regulations of the Commission under
the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule
424(b)") of the 1933 Act Regulations or (ii) if the Company has elected to rely
upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term
sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule
424(b).  Two forms of prospectus are to be used in connection with the offering
and sale of the Securities:  one relating to the International Securities (the
"Form of International Prospectus") and one relating to the U.S. Securities
(the "Form of U.S. Prospectus").  The Form of International Prospectus is
identical to the Form of U.S. Prospectus, except for the front cover and back
cover pages and the information under the caption "Underwriting" [and the
inclusion in the Form of International Prospectus of a section under the
caption "Certain United States Tax Considerations for Non-United States
Holders."]  The information included in any such prospectus or in any such Term
Sheet, as the case may be, that was omitted from such registration statement at
the time it became effective but that is deemed to be part of such registration
statement at the time it became effective (a) pursuant to paragraph (b) of Rule
430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph (d)
of Rule 434 is referred to as "Rule 434 Information."  Each Form of
International Prospectus and Form of U.S. Prospectus used before such
registration statement became effective, and any prospectus that omitted, as
applicable, the Rule 430A

Information or the Rule 434 Information, that was used after such effectiveness
and prior to the execution and delivery of this Agreement, is herein called a
"preliminary prospectus."  Such registration statement, including the exhibits
thereto and schedules thereto at the time it became effective and including the
Rule 430A Information and the Rule 434 Information, as applicable, is herein
called the "Registration Statement."  Any registration statement filed pursuant
to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule
462(b) Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement.  The final
Form of International Prospectus and the final Form of U.S. Prospectus in the
forms first furnished to the Underwriters for use in connection with the
offering of the Securities are herein called the "International Prospectus" and
the "U.S.  Prospectus," respectively, and collectively, the "Prospectuses."
For purposes of this Agreement, all references to the Registration Statement,
any preliminary prospectus, the International Prospectus, the U.S. Prospectus
or any Term Sheet or any amendment or supplement to any of the foregoing shall
be deemed to include the copy filed with the Commission pursuant to its
Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

         At the Closing Time (defined below), the Company will acquire all of
the outstanding capital stock or other equity interests of each of the
companies listed on Schedule D (each, a "Founding Company" and, collectively,
the "Founding Companies"), in each case pursuant to a stock purchase agreement
(each an "Acquisition Agreement" and, collectively, the "Acquisition
Agreements"), each as described in the Prospectuses under the caption "Certain
Transactions -  Organization of the Company" (collectively, the "Combination").

International Manager, as follows:

                 (i)      Compliance with Registration Requirements.  Each of
         the Registration Statement and any Rule 462(b) Registration Statement
         has become effective under the 1933 Act and no stop order suspending
         the effectiveness of the Registration Statement or any Rule 462(b)
         Registration Statement has been issued under the 1933 Act and no
         proceedings for that purpose have been instituted or are pending or,
         to the knowledge of the Company, are contemplated by the Commission,
         and any request on the part of the Commission for additional
         information has been complied with.

                 At the respective times the Registration Statement, any Rule
         462(b) Registration Statement and any post-effective amendments
         thereto became effective and at the Closing Time (and, if any
         International Option Securities are purchased, at the Date of
         Delivery), the Registration Statement, the Rule 462(b) Registration
         Statement and any amendments and supplements thereto complied and will
         comply in all material respects with the requirements of the 1933 Act
         and the 1933 Act Regulations and did not and will not contain an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading.  Neither of the Prospectuses nor any
         amendments or supplements thereto, at the time the Prospectuses or any
         amendments or supplements thereto were issued and at the Closing Time
         (and, if any International Option Securities are purchased, at the
         Date of Delivery), included or will include an untrue statement of a
         material fact or omitted or will omit to state a material fact
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.  If Rule 434
         is used, the Company will comply with the requirements of Rule 434 and
         the Prospectuses





                                       3

         shall not be "materially different", as such term is used in Rule 434,
         from the prospectuses included in the Registration Statement at the
         time it became effective.  The representations and warranties in this
         subsection shall not apply to statements in or omissions from the
         Registration Statement or the International Prospectus made in reliance
         upon and in conformity with information furnished to the Company in
         writing by any International Manager through the Lead Managers
         expressly for use in the Registration Statement or the International
         Prospectus.

                 Each preliminary prospectus and the prospectuses filed as part
         of the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
         complied when so filed in all material respects with the 1933 Act
         Regulations and each preliminary prospectus and the Prospectuses
         delivered to the Underwriters for use in connection with this offering
         was identical to the electronically transmitted copies thereof filed
         with the Commission pursuant to EDGAR, except to the extent permitted
         by Regulation S-T.

                 (ii)     Independent Accountants.  The accountants who
         certified the financial statements and supporting schedules included
         in the Registration Statement are independent public accountants as
         required by the 1933 Act and the 1933 Act Regulations.

                 (iii)    Financial Statements.  The financial statements
         included in the Registration Statement and the Prospectuses, together
         with the related schedules and notes, present fairly the financial
         position of the Company, the Founding Companies, and their respective
         consolidated subsidiaries at the dates indicated and the statement of
         operations, stockholders' equity and cash flows of the Company, the
         Founding Companies and their consolidated subsidiaries for the periods
         specified; said financial statements have been prepared in conformity
         with generally accepted accounting principles ("GAAP") applied on a
         consistent basis throughout the periods involved.  The supporting
         schedules included in the Registration Statement present fairly in
         accordance with GAAP the information required to be stated therein.
         The selected financial data and the summary financial information
         included in the Prospectuses present fairly the information shown
         therein and have been compiled on a basis consistent with that of the
         audited financial statements included in the Registration Statement.
         The pro forma financial statements and the related notes thereto
         included in the Registration Statement and the Prospectuses present
         fairly the information shown therein, have been prepared in accordance
         with the Commission's rules and guidelines with respect to pro forma
         financial statements and have been properly compiled on the bases
         described therein, and the assumptions used in the preparation thereof
         are reasonable and the adjustments used therein are appropriate to
         give effect to the transactions and circumstances referred to therein.

                 (iv)     No Material Adverse Change in Business.  Since the
         respective dates as of which information is given in the Registration
         Statement and the Prospectuses, except as otherwise stated therein,
         (A) there has been no material adverse change in the condition,
         financial or otherwise, or in the earnings, business affairs or
         business prospects of the Company, the Founding Companies and their
         respective subsidiaries considered as one enterprise, whether or not
         arising in the ordinary course of business (a "Material Adverse
         Effect"), (B) there have been no transactions entered into by the
         Company, the Founding Companies or their respective subsidiaries,
         other than those in the ordinary course of business, which are
         material with respect to the Company, the Founding Companies and their
         respective subsidiaries considered as one enterprise, and (C) there
         has been no dividend or distribution of any kind declared, paid or
         made by the Company on any class of its capital stock or, except as
         set forth in the Prospectuses, by any Founding Company on any class of
         its capital stock.

                 (v)      Good Standing of the Company.  The Company has been
         duly organized and is validly existing as a corporation in good
         standing under the laws of the State of Delaware and has corporate
         power and authority to own, lease and operate its properties and to
         conduct its business as described in the Prospectuses and to enter
         into and perform its obligations under this Agreement.  The Company is
         duly qualified as a foreign corporation to transact business and is in
         good standing in each other jurisdiction in which such qualification
         is required, whether by reason of the ownership or leasing of property
         or the conduct of business, except where the failure so to qualify or
         to be in good standing would not result in a Material Adverse Effect.

                 (vi)     Good Standing of Founding Companies.  The Company has
         no subsidiaries as of the date hereof.  As of the Closing Time, the
         only subsidiaries of the Company will be the Founding Companies and
         their respective subsidiaries.  Each Founding Company or subsidiary
         thereof that is a corporation has been duly organized and is validly
         existing as a corporation in good standing under the laws of the
         jurisdiction of its incorporation, has corporate power and authority
         to own, lease and operate its properties and to conduct its business
         as described in the Prospectuses and is duly qualified as a foreign
         corporation to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct of
         business, except where the failure so to qualify or to be in good
         standing would not result in a Material Adverse Effect.  Except as
         otherwise disclosed in the Registration Statement, all of the issued
         and outstanding capital stock of each Founding Company or subsidiary
         has been duly authorized and validly issued, is fully paid and
         non-assessable, and upon consummation of the Combination, will be
         owned by the Company, directly or through subsidiaries, free and clear
         of any security interest, mortgage, pledge, lien, encumbrance, claim
         or equity.  None of the outstanding shares of capital stock of any
         founding company subsidiary was issued in violation of the preemptive
         or similar rights of any security holder of such subsidiary.  Each
         Founding Company or subsidiary thereof that is a partnership or
         limited liability company has been duly formed and is validly existing
         in good standing under the laws of the jurisdiction of organization,
         has power and authority to own, lease and operate its properties and
         to conduct its business as described in the Prospectuses and is duly
         qualified to transact business and is in good standing in each
         jurisdiction in which such qualification is required, whether by
         reason of the ownership or leasing of property or the conduct of
         business, except where the failure so to qualify or to be in good
         standing would not result in a Material Adverse Effect.  Exhibit 21 to
         the Registration Statement sets forth a complete list of the Founding
         Companies and their subsidiaries, except to the extent permitted by
         the rules and regulations of the Commission.

                 (vii)    Capitalization.  As of the Closing Time, the Company
         had authorized capital stock consisting of 100,000,000 shares of
         Common Stock, par value $.01 per share, and 10,000,000 shares of
         Preferred Stock, par value $.01 per share (the "Preferred Stock").
         Prior to the closing of  the transactions contemplated by each of the
         Acquisition Agreements and the issuance of shares of Common Stock as
         contemplated thereby and by the U.S. Purchase Agreement and the
         International Purchase Agreement, the Company had issued and
         outstanding 4,052,311 shares of Common Stock and no shares of
         Preferred Stock; upon  consummation of the Combination and the
         issuance of 12,313,026 shares of Common Stock as contemplated by the
         Acquisition Agreements, (which, together with the 4,052,311 shares of
         Common Stock issued prior to the Combination, are all the shares of
         Common Stock issued or to be issued prior to the issuance and sale of
         the Securities), but without giving effect to the issuance of the
         Securities pursuant to the terms of the U.S. Purchase Agreement and
         the International Purchase Agreement, the Company will have issued and
         outstanding 16,365,337 shares of Common Stock and no shares of
         Preferred Stock.   All of such shares of Common Stock have been duly
         authorized and, when issued and delivered to the





                                       5
<PAGE>   9
         purchasers thereof against payment therefor as provided in the
         Acquisition Agreements, will be validly issued, fully paid and
         nonassessable.  None of the outstanding shares of capital stock of the
         Company was issued in violation of the preemptive or other similar
         rights of any security holder of the Company.  Except as described in
         the Prospectuses, there are no outstanding options, warrants or other
         rights calling for the issuance of, and there are no commitments to
         issue any shares of, capital stock of the Company or any security
         convertible into or exchangeable or exercisable for capital stock of
         the Company.

                 (viii)   Authorization of Agreement.  This Agreement and the
         U.S. Purchase Agreement have been duly authorized, executed and
         delivered by the Company.

                 (ix)     Authorization and Description of Securities.  The
         Securities to be purchased by the International Managers and the U.S.
         Underwriters from the Company have been duly authorized for issuance
         and sale to the International Managers pursuant to this Agreement and
         the U.S. Underwriters pursuant to the U.S.  Purchase Agreement,
         respectively, and, when issued and delivered by the Company pursuant
         to this Agreement and the U.S. Purchase Agreement, respectively,
         against payment of the consideration set forth herein and the U.S.
         Purchase Agreement, respectively, will be validly issued, fully paid
         and non-assessable.  The Common Stock conforms to all statements
         relating thereto contained in the Prospectuses and such description
         conforms to the rights set forth in the instruments defining the same.
         No holder of the Securities will be subject to personal liability by
         reason of being such a holder.  The issuance of the Securities is not
         subject to the preemptive or other similar rights of any security
         holder of the Company.

                 (x)      Absence of Defaults and Conflicts.  Neither the
         Company nor any of the Founding Companies or their respective
         subsidiaries is in violation of its charter or by-laws or in default
         in the performance or observance of any obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         deed of trust, loan or credit agreement, note, lease or other
         agreement or instrument to which the Company, any Founding Company or
         any of their respective subsidiaries is a party or by which it or any
         of them may be bound, or to which any of the property or assets of the
         Company or any subsidiary is subject (collectively, "Agreements and
         Instruments") except for such defaults that would not result in a
         Material Adverse Effect.  The execution, delivery and performance of
         this Agreement, the U.S. Purchase Agreement, and the Acquisition
         Agreements and the consummation of the transactions contemplated in
         this Agreement, the U.S. Purchase Agreement and in the Registration
         Statement (including the issuance and sale of the Securities and the
         use of the proceeds from the sale of the Securities as described in
         the Prospectuses under the caption "Use of Proceeds") and compliance
         by the Company with its obligations under this Agreement, the U.S.
         Purchase Agreement and the Acquisition Agreements have been duly
         authorized by all necessary corporate action and do not and will not,
         whether with or without the giving of notice or passage of time or
         both, conflict with or constitute a breach of, or default or Repayment
         Event (as defined below) under, or result in the creation or
         imposition of any lien, charge or encumbrance upon any property or
         assets of the Company, any Founding Company or any subsidiary pursuant
         to, the Agreements and Instruments (except for such conflicts,
         breaches or defaults or liens, charges or encumbrances that would not
         result in a Material Adverse Effect), nor will such action result in
         any violation of the provisions of the charter or by-laws of the
         Company, any Founding Company or any subsidiary thereof or any
         applicable law, statute, rule, regulation, judgment, order, writ or
         decree of any government, government instrumentality or court,
         domestic or foreign, having jurisdiction over the Company, any
         Founding Company or any subsidiary thereof or any of their assets,
         properties or operations.  As used herein, a "Repayment Event" means
         any event or condition which gives the holder of any note,





                                       6
<PAGE>   10
         debenture or other evidence of indebtedness (or any person acting on
         such holder's behalf) the right to require the repurchase, redemption
         or repayment of all or a portion of such indebtedness by the Company,
         any Founding Company or any subsidiary thereof.

                 (xi)     Absence of Labor Dispute.  No labor dispute with the
         employees of the Company, any Founding Company or any subsidiary
         thereof exists or, to the knowledge of the Company, is imminent, and
         neither the Company nor any Founding Company is aware of any existing
         or imminent labor disturbance by the employees of any of its or any
         subsidiary's principal suppliers, manufacturers, customers or
         contractors, which, in either case, may reasonably be expected to
         result in a Material Adverse Effect.

                 (xii)    Absence of Proceedings.  There is no action, suit,
         proceeding, inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign, now pending, or, to
         the knowledge of the Company, threatened, against or affecting the
         Company, any Founding Company or any subsidiary thereof, which is
         required to be disclosed in the Registration Statement (other than as
         disclosed therein), or which might reasonably be expected to result in
         a Material Adverse Effect, or which might reasonably be expected to
         materially and adversely affect the properties or assets thereof or
         the consummation of the transactions contemplated in this Agreement,
         the U.S. Purchase Agreement or the Acquisition Agreements or the
         performance by the Company of its obligations hereunder or thereunder;
         the aggregate of all pending legal or governmental proceedings to
         which the Company, any Founding Company  or any subsidiary thereof is
         a party or of which any of their respective property or assets is the
         subject which are not described in the Registration Statement,
         including ordinary routine litigation incidental to the business,
         could not reasonably be expected to result in a Material Adverse
         Effect.

                 (xiii)   Accuracy of Exhibits.  There are no contracts or
         documents which are required to be described in the Registration
         Statement or the Prospectuses or to be filed as exhibits thereto which
         have not been so described and filed as required.

                 (xiv)    Possession of Intellectual Property.  The Company,
         the Founding Companies and their subsidiaries own or possess, or can
         acquire on reasonable terms, adequate patents, patent rights,
         licenses, inventions, copyrights, know-how (including trade secrets
         and other unpatented and/or unpatentable proprietary or confidential
         information, systems or procedures), trademarks, service marks, trade
         names or other intellectual property (collectively, "Intellectual
         Property") necessary to carry on the business now operated by them,
         and neither the Company, any Founding Company nor any of its
         subsidiaries has received any notice or is otherwise aware of any
         infringement of or conflict with asserted rights of others with
         respect to any Intellectual Property or of any facts or circumstances
         which would render any Intellectual Property invalid or inadequate to
         protect the interest of the Company, such Founding Company or any of
         its subsidiaries therein, and which infringement or conflict (if the
         subject of any unfavorable decision, ruling or finding) or invalidity
         or inadequacy, singly or in the aggregate, would result in a Material
         Adverse Effect.

                 (xv)     Absence of Further Requirements.  No filing with, or
         authorization, approval, consent, license, order, registration,
         qualification or decree of, any court or governmental authority or
         agency is necessary or required for the performance by the Company of
         its obligations hereunder, in connection with the offering, issuance
         or sale of the Securities under this Agreement and the U.S. Purchase
         Agreement or the consummation of the transactions contemplated by this
         Agreement, the U.S. Purchase Agreement or the Acquisition Agreements,
         except such as have been already obtained or as may be required under
         the 1933 Act or the 1933 Act Regulations and foreign or state
         securities or blue sky laws.





                                       7
<PAGE>   11
                 (xvi)    Possession of Licenses and Permits.  The Company,
         each Founding Company and their subsidiaries possess such permits,
         licenses, approvals, consents and other authorizations (collectively,
         "Governmental Licenses") issued by the appropriate federal, state,
         local or foreign regulatory agencies or bodies necessary to conduct
         the business now operated by them.  The Company, each Founding Company
         and their subsidiaries are in compliance with the terms and conditions
         of all such Governmental Licenses, except where the failure so to
         comply would not, singly or in the aggregate, have a Material Adverse
         Effect.  All of the Governmental Licenses are valid and in full force
         and effect, except when the invalidity of such Governmental Licenses
         or the failure of such Governmental Licenses to be in full force and
         effect would not have a Material Adverse Effect.  Neither the Company
         nor any Founding Company or their subsidiaries has received any notice
         of proceedings relating to the revocation or modification of any such
         Governmental Licenses which, singly or in the aggregate, if the
         subject of an unfavorable decision, ruling or finding, would result in
         a Material Adverse Effect.

                 (xvii)   Title to Property.  The Company, each Founding
         Company and their subsidiaries have good and marketable title to all
         real property owned by them and good title to all other properties
         owned by them, in each case, free and clear of all mortgages, pledges,
         liens, security interests, claims, restrictions or encumbrances of any
         kind except such as (a) are described in the Prospectuses or (b) do
         not, singly or in the aggregate, materially affect the value of such
         property and do not interfere with the use made and proposed to be
         made of such property by the Company, the Founding Companies or any of
         their subsidiaries.  All of the leases and subleases material to the
         business of the Company, the Founding Companies or any of their
         subsidiaries, considered as one enterprise, and under which the
         Company, the Founding Company or any of their subsidiaries holds
         properties described in the Prospectuses, are in full force and
         effect, and neither the Company nor any Founding Company or any of
         their subsidiaries has any notice of any material claim of any sort
         that has been asserted by anyone adverse to the rights of the Company,
         such Founding Company or any subsidiary under any of the leases or
         subleases mentioned above, or affecting or questioning the rights of
         the Company, such Founding Company or such subsidiary to the continued
         possession of the leased or subleased premises under any such lease or
         sublease.

                 (xviii)  Compliance with Cuba Act.  The Company has complied
         with, and is and will be in compliance with, the provisions of that
         certain Florida act relating to disclosure of doing business with
         Cuba, codified as Section 517.075 of the Florida statutes, and the
         rules and regulations thereunder (collectively, the "Cuba Act") or is
         exempt therefrom.

                 (xix)    Investment Company Act.  The Company is not, and upon
         the issuance and sale of the Securities as herein contemplated, the
         application of the net proceeds therefrom as described in the
         Prospectuses or consummation of the Combination will not be, an
         "investment company" or an entity "controlled" by an "investment
         company" as such terms are defined in the Investment Company Act of
         1940, as amended (the "1940 Act").

         Registration Statement and except as would not, singly or in the
         aggregate, result in a Material Adverse Effect, (A) neither the
         Company, any Founding Company or any subsidiary thereof is in
         violation of any federal, state, local or foreign statute, law, rule,
         regulation, ordinance, code, policy or rule of common law or any

         without limitation, ambient air, surface water, groundwater, land
         surface or subsurface strata) or wildlife, including, without

         Laws"), (B) the Company, the Founding Companies and their

         an action, suit or proceeding by any private party or governmental
         body or agency, against or affecting the Company, any Founding Company
         or any of their subsidiaries relating to Hazardous Materials or any
         Environmental Laws.

                 (xxi)    Registration Rights.  There are no persons with
         registration rights or other similar rights to have any securities

         income tax returns which have been required to be filed and have paid
         all taxes indicated by said returns and all assessments received by it
         or any of them to the extent that such taxes have become due and are

         Material Adverse Effect.  All tax liabilities have been adequately

         applicable Founding Company.

                 (xxiii)  Insurance.  The Company and the Founding Companies
         and their subsidiaries carry, or are covered by, insurance in such
         amounts and covering such risks as is reasonably adequate for the
         conduct of their respective businesses and the value of their
         respective properties and as is customary for companies in the
         Company's industry.

                 (xxiv)   ERISA.  The Company and the Founding Companies and

         presently applicable provisions of the Employee Retirement Income
         Security Act of 1974, as amended, including the regulations and
         published interpretations thereunder ("ERISA").

         or indirect, exists between or among the Company or any Founding
         Company or subsidiary, on the one hand, and the directors, officers,
         shareholders, customers or suppliers of the Company, such Founding
         Company or its subsidiaries on the other hand, which is required to be
         described in the Prospectuses which is not so described.

                 (xxvi)   Reserved Shares.  Each of the persons identified by
         the Company to the Underwriters to receive Reserved Shares is a
         citizen of the United States and currently is a resident of one of the
         United States.

                 (xxvii)  Consummation of Combination.   As of the date of this
         Agreement, all conditions to consummation of the transactions
         contemplated by each Acquisition Agreement have been satisfied, with
         the exception of the Closing of the sale of the Securities pursuant to
         this Agreement and the U.S. Purchase Agreement.   There have been no
         amendments or supplements to any of the Acquisition Agreements since
         the original execution thereof on October 21, 1997.  The Company has
         notified the Underwriters of any waiver of any conditions to
         consummation of such Acquisition Agreements.  The Closing (as defined
         in the Acquisition Agreements) with respect to each Acquisition
         Agreement has occurred.  At or prior to the Closing Time, the
         transactions contemplated by each Acquisition Agreement will be
         consummated, with the result that each Founding Company will become a
         wholly- owned direct or indirect subsidiary of the Company as
         described in the Prospectuses.

         (b)     Officer's Certificates.  Any certificate signed by any officer
of the Company or any of its subsidiaries delivered to the Global Coordinator,
the Lead Managers or to counsel for the International Managers shall be deemed
a representation and warranty by the Company to each International Manager as
to the matters covered thereby.

         SECTION 2.       Sale and Delivery to International Managers; Closing.

         (a)     Initial Securities.  On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein  set
forth, the Company agrees to sell to each International Manager, severally and
not jointly, and each International Manager, severally and not jointly, agrees
to purchase from the Company, at the price per share set forth in Schedule B,
the number of Initial International Securities set forth in Schedule A opposite
the name of such International Manager, plus any additional number of Initial
International Securities which such International Manager may become obligated
to purchase pursuant to the provisions of Section 10 hereof.

         (b)     Option Securities.  In addition, on the basis of the
representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Company hereby grants an option to the
International Managers, severally and not jointly, to purchase up to an
additional 210,000 shares of Common Stock at the price per share set forth in
Schedule B, less an amount per share equal to any dividends or distributions
declared by the Company and payable on the Initial International Securities but
not payable on the International Option Securities.  The option hereby granted
will expire 30 days after the date hereof and may be exercised in whole or in
part from time to time only for the purpose of covering over-allotments which
may be made in connection with the offering and distribution of the Initial
International Securities upon notice by the Global Coordinator to the Company
setting forth the number of International Option Securities as to which the
several International Managers are then exercising the option and the time and
date of payment and delivery for such International Option Securities.  Any
such time and date of delivery for the International Option Securities (a "Date
of Delivery") shall be determined by the Global Coordinator, but shall not be
later than seven full business days after the exercise of said option, nor in
any event prior to the Closing Time, as hereinafter defined.  If the option is
exercised as to all or any portion of the International Option Securities, each
of the International Managers, acting severally and not jointly, will purchase
that proportion of the total number of International Option Securities then
being purchased which the number of Initial International Securities set forth
in Schedule A opposite the name of such International Manager bears to the
total number





                                       10
<PAGE>   14
of Initial International Securities, subject in each case to such adjustments
as the Global Coordinator in its discretion shall make to eliminate any sales
or purchases of fractional shares.

         (c)     Payment.  Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of Vinson
& Elkins L.L.P., 1001 Fannin, Houston, Texas, or at such other place as shall
be agreed upon by the Global Coordinator and the Company, at 9:00 A.M. (Eastern
time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern
time) on any given day) business day after the date hereof (unless postponed in
accordance with the provisions of Section 10), or such other time not later
than ten business days after such date as shall be agreed upon by the Global
Coordinator and the Company (such time and date of payment and delivery being
herein called "Closing Time").

         In addition, in the event that any or all of the International Option
Securities are purchased by the International Managers, payment of the purchase
price for, and delivery of certificates for, such International Option
Securities shall be made at the above-mentioned offices, or at such other place
as shall be agreed upon by the Global Coordinator and the Company, on each Date
of Delivery as specified in the notice from the Global Coordinator to the
Company.

         Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery
to the Lead Managers for the respective accounts of the International Managers
of certificates for the International Securities to be purchased by them.  It
is understood that each International Manager has authorized the Lead Managers,
for its account, to accept delivery of, receipt for, and make payment of the
purchase price for, the Initial International Securities and the International
Option Securities, if any, which it has agreed to purchase.  Merrill Lynch,
individually and not as representative of the International Managers, may (but
shall not be obligated to) make payment of the purchase price for the Initial
International Securities or the International Option Securities, if any, to be
purchased by any International Manager whose funds have not been received by
the Closing Time or the relevant Date of Delivery, as the case may be, but such
payment shall not relieve such International Manager from its obligations
hereunder.

         (d)     Denominations; Registration.  Certificates for the Initial
International Securities and the International Option Securities, if any, shall
be in such denominations and registered in such names as the Lead Managers may
request in writing at least one full business day before the Closing Time or
the relevant Date of Delivery, as the case may be.  The certificates for the
Initial International Securities and the International Option Securities, if
any, will be made available for examination and packaging by the Lead Managers
in The City of New York not later than 10:00 A.M. (Eastern time) on the
business day prior to the Closing Time or the relevant Date of Delivery, as the
case may be.

         SECTION 3.       Covenants of the Company.  The Company covenants with
each International Manager as follows:

         (a)     Compliance with Securities Regulations and Commission
Requests.  The Company, subject to Section 3(b), will comply with the
requirements of Rule 430A or Rule 434, as applicable, and will notify the
Global Coordinator immediately, and confirm the notice in writing, (i) when any
post-effective amendment to the Registration Statement shall become effective,
or any supplement to the Prospectuses or any amended Prospectuses shall have
been filed, (ii) of the receipt of any comments from the Commission, (iii) of
any request by the Commission for any amendment to the Registration Statement
or any amendment or supplement to the Prospectuses or for additional
information, and (iv) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement or of any order
preventing or suspending the use





                                       11
<PAGE>   15
of any preliminary prospectus, or of the suspension of the qualification of the
Securities for offering or sale in any jurisdiction, or of the initiation or
threatening of any proceedings for any of such purposes.  The Company will
promptly effect the filings necessary pursuant to Rule 424(b) and will take
such steps as it deems necessary to ascertain promptly whether the form of
prospectus transmitted for filing under Rule 424(b) was received for filing by
the Commission and, in the event that it was not, it will promptly file such
prospectus.  The Company will make every reasonable effort to prevent the
issuance of any stop order and, if any stop order is issued, to obtain the
lifting thereof at the earliest possible moment.

         (b)     Filing of Amendments.  The Company will give the Global
Coordinator notice of its intention to file or prepare any amendment to the
Registration Statement (including any filing under Rule 462(b)), any Term Sheet
or any amendment, supplement or revision to either the prospectus included in
the Registration Statement at the time it became effective or to the
Prospectuses, will furnish the Global Coordinator with copies of any such
documents a reasonable amount of time prior to such proposed filing or use, as
the case may be, and will not file or use any such document to which the Global
Coordinator or counsel for the International Managers shall object.

         (c)     Delivery of Registration Statements.  The Company has
furnished or will deliver to the Lead Managers and counsel for the
International Managers, without charge, signed copies of the Registration
Statement as originally filed and of each amendment thereto (including exhibits
filed therewith or incorporated by reference therein) and signed copies of all
consents and certificates of experts, and will also deliver to the Lead
Managers, without charge, a conformed copy of the Registration Statement as
originally filed and of each amendment thereto (without exhibits) for each of
the International Managers.  The copies of the Registration Statement and each
amendment thereto furnished to the International Managers will be identical to
the electronically transmitted copies thereof filed with the Commission
pursuant to EDGAR, except to the extent permitted by Regulation S-T.

         (d)     Delivery of Prospectuses.  The Company has delivered to each
International Manager, without charge, as many copies of each preliminary
prospectus as such International Manager reasonably requested, and the Company
hereby consents to the use of such copies for purposes permitted by the 1933
Act.  The Company will furnish to each International Manager, without charge,
during the period when the International Prospectus is required to be delivered
under the 1933 Act or the Securities Exchange Act of 1934 (the "1934 Act"),
such number of copies of the International Prospectus (as amended or
supplemented) as such International Manager may reasonably request.  The
International Prospectus and any amendments or supplements thereto furnished to
the International Managers will be identical to the electronically transmitted
copies thereof filed with the Commission pursuant to EDGAR, except to the
extent permitted by Regulation S-T.

         (e)     Continued Compliance with Securities Laws.  The Company will
comply with the 1933 Act and the 1933 Act Regulations so as to permit the
completion of the distribution of the Securities as contemplated in this
Agreement, the U.S. Purchase Agreement and in the Prospectuses.  If at any time
when a prospectus is required by the 1933 Act to be delivered in connection
with sales of the Securities, any event shall occur or condition shall exist as
a result of which it is necessary, in the opinion of counsel for the
International Managers or for the Company, to amend the Registration Statement
or amend or supplement any Prospectus in order that the Prospectuses will not
include any untrue statements of a material fact or omit to state a material
fact necessary in order to make the statements therein not misleading in the
light of the circumstances existing at the time it is delivered to a purchaser,
or if it shall be necessary, in the opinion of such counsel, at any such time
to amend the Registration Statement or amend or supplement any Prospectus in
order to comply with the requirements of the 1933 Act or the 1933 Act
Regulations, the Company will





                                       12
<PAGE>   16
promptly prepare and file with the Commission, subject to Section 3(b), such
amendment or supplement as may be necessary to correct such statement or
omission or to make the Registration Statement or the Prospectuses comply with
such requirements, and the Company will furnish to the International Managers
such number of copies of such amendment or supplement as the International
Managers may reasonably request.

         (f)     Blue Sky Qualifications.  The Company will use its best
efforts, in cooperation with the International Managers, to qualify the
Securities for offering and sale under the applicable securities laws of such
states and other jurisdictions (domestic or foreign) as the Global Coordinator
may designate and to maintain such qualifications in effect for a period of not
less than one year from the later of the effective date of the Registration
Statement and any Rule 462(b) Registration Statement; provided, however, that
the Company shall not be obligated to file any general consent to service of
process or to qualify as a foreign corporation or as a dealer in securities in
any jurisdiction in which it is not so qualified or to subject itself to
taxation in respect of doing business in any jurisdiction in which it is not
otherwise so subject.  In each jurisdiction in which the Securities have been
so qualified, the Company will file such statements and reports as may be
required by the laws of such jurisdiction to continue such qualification in
effect for a period of not less than one year from the effective date of the
Registration Statement and any Rule 462(b) Registration Statement.

         (g)     Rule 158.  The Company will timely file such reports pursuant
to the 1934 Act as are necessary in order to make generally available to its
security holders as soon as practicable an earnings statement for the purposes
of, and to provide the benefits contemplated by, the last paragraph of Section
11(a) of the 1933 Act.

         (h)     Use of Proceeds.  The Company will use the net proceeds
received by it from the sale of the Securities in the manner specified in the
Prospectuses under "Use of Proceeds".

         (i)     Listing.  The Company will use its best efforts to effect the
listing of the Securities Common Stock (including the Securities) on the New
York Stock Exchange.

         (j)     Restriction on Sale of Securities.  During a period of 180
days from the date of the Prospectuses, the Company will not, without the prior
written consent of the Global Coordinator, (i) directly or indirectly, offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of any share of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock or
file any registration statement under the 1933 Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Common Stock or any securities convertible into
or exercisable or exchangeable for Common Stock, whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise.  The foregoing
sentence shall not apply to (A) the Securities to be sold hereunder or under
the U.S. Purchase Agreement or in connection with the Combination as described
in the Prospectuses, (B) any shares of Common Stock issued or options to
purchase Common Stock granted pursuant to employee benefit plans of the Company
referred to in the Prospectuses or (C) shares of Common Stock issued in
connection with acquisitions by the Company of other businesses, provided that,
(except with respect to shares issued in transactions in which the issuance or
resale of such shares will not be registered under the 1933 Act) the recipients
of such shares agree in writing for the benefit of the International Managers
not to take any action described in clauses (i) or (ii) above with respect to
such shares until the expiration of 180 days from the date of the Prospectuses.

         (k)     Reporting Requirements.  The Company, during the period when
the Prospectuses are required to be delivered under the 1933 Act or the 1934
Act, will file all documents required to be filed with the Commission pursuant
to the 1934 Act within the time periods required by the 1934 Act and the rules
and regulations of the Commission thereunder.

         (l)     Compliance with NASD Rules.  The Company hereby agrees that it
will ensure that the Reserved Securities will be restricted as required by the
National Association of Securities Dealers, Inc. (the "NASD") or the NASD rules
from sale, transfer, assignment, pledge or hypothecation for a period of three
months following the date of this Agreement.  The Underwriters will notify the
Company as to which persons will need to be so restricted.  At the request of
the Underwriters, the Company will direct the transfer agent to place a stop
transfer restriction upon such securities for such period of time.  Should the
Company release, or seek to release, from such restrictions any of the Reserved
Securities, the Company agrees to reimburse the Underwriters for any reasonable
expenses (including, without limitation, legal expenses) they incur in
connection with such release.

         (m)     Compliance with Rule 463.  The Company will file with the
Commission such reports on Form SR as may be required pursuant to Rule 463 of
the 1933 Act Regulations.

thereto, (ii) the preparation, printing and delivery to the Underwriters of
this Agreement, any Agreement among Underwriters and such other documents as

(iv) the fees and disbursements of the Company's counsel, accountants and other
advisors, (v) the qualification of the Securities under securities laws in

Underwriters of copies of each preliminary prospectus, any Term Sheets and of

conditions:

         (a)     Effectiveness of Registration Statement.  The Registration

         (m)     Additional Documents.  At Closing Time and at each Date of

         (n)     Termination of Agreement.  If any condition specified in this

Closing Time, the obligations of the several International Managers to purchase
the relevant Option Securities may be terminated by the Lead Managers by notice
to the Company at any time at or prior to Closing Time or such Date of
Delivery, as the case may be, and such  termination shall be without liability
of any party to any other party except as provided in Section 4 and except that
Sections 1, 6, 7 and 8 shall survive any such termination and remain in full
force and effect.

         SECTION 6.       Indemnification.

         (a)     Indemnification of International Managers.  The Company agrees
to indemnify and hold harmless each International Manager and each person, if
any, who controls any International Manager within the meaning of Section 15 of
the 1933 Act or Section 20 of the 1934 Act as follows:

                 (i)      against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Registration Statement (or any amendment thereto), including the
         Rule 430A Information and the Rule 434 Information, if applicable, or
         the omission or alleged omission therefrom of a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact included in any preliminary prospectus or
         the Prospectuses (or any amendment or supplement thereto), or the
         omission or alleged





                                       17
<PAGE>   21
         omission therefrom of a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading;

                 (ii)     against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, to the extent of the aggregate
         amount paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission; provided that (subject to Section 6(d) below) any such
         settlement is effected with the written consent of the Company; and

                 (iii)    against any and all expense whatsoever, as incurred
         (including the fees and disbursements of counsel chosen by Merrill
         Lynch), reasonably incurred in investigating, preparing or defending
         against any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
International Manager through the Lead Managers expressly for use in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any preliminary
prospectus or the International Prospectus (or any amendment or supplement
thereto).

         (b)     Indemnification of Company, Directors and Officers.  Each
International Manager severally agrees to indemnify and hold harmless the
Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all
loss, liability, claim, damage and expense described in the indemnity contained
in subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information, if applicable, or any preliminary
international prospectus or the International Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by such International Manager through the Lead
Managers expressly for use in the Registration Statement (or any amendment
thereto) or such preliminary prospectus or the International Prospectus (or any
amendment or supplement thereto).

         (c)     Actions against Parties; Notification.  Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it
is not materially prejudiced as a result thereof and in any event shall not
relieve it from any liability which it may have otherwise than on account of
this indemnity agreement.  In the case of parties indemnified pursuant to
Section 6(a) above, counsel to the indemnified parties shall be selected by
Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b)
above, counsel to the indemnified parties shall be selected by the Company.  An
indemnifying party may participate at its own expense in the defense of any
such action; provided, however, that counsel to the indemnifying party shall
not (except with the consent of the indemnified party) also be counsel to the
indemnified party.  In no event shall the indemnifying parties be liable for
fees and expenses of more than one





                                       18
<PAGE>   22
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances.  No indemnifying party shall, without the
prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 6 or Section 7 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.

         (d)     Settlement without Consent if Failure to Reimburse.  If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 6(a)(ii) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

         (e)     Indemnification for Reserved Securities.  In connection with
the offer and sale of the Reserved Securities, the Company agrees, promptly
upon a request in writing, to indemnify and hold harmless the Underwriters from
and against any and all losses, liabilities, claims, damages and expenses
incurred by them as a result of the failure of any person or entity to whom
Reserved Securities are offered to pay for and accept delivery of Reserved
Securities which, by the end of the first business day following the date of
this Agreement, were subject to a properly confirmed agreement to purchase.

         SECTION 7.       Contribution.  If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the International Managers on the other hand from
the offering of the Securities pursuant to this Agreement or (ii) if the
allocation provided by clause (i) is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and of the International Managers on the other hand in connection with the
statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations.

         The relative benefits received by the Company on the one hand and the
International Managers on the other hand in connection with the offering of the
International Securities pursuant to this Agreement shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
the International Securities pursuant to this Agreement (before deducting
expenses) received by the Company and the total underwriting discount received
by the International Managers, in each case as set forth on the cover of the
International Prospectus, or, if Rule 434 is used, the corresponding location
on the Term Sheet, bear to the aggregate initial public offering price of the
International Securities as set forth on such cover.





                                       19
<PAGE>   23
         The relative fault of the Company on the one hand and the
International Managers on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company or by the International Managers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

         The Company and the International Managers agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined
by pro rata allocation (even if the International Managers were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
7.  The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 7 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

         Notwithstanding the provisions of this Section 7, no International
Manager shall be required to contribute any amount in excess of the amount by
which the total price at which the International Securities underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such International Managers has otherwise been required to
pay by reason of any such untrue or alleged untrue statement or omission or
alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls an
International Managers within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
International Manager, and each director of the Company, each officer of the
Company who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as the
Company.  The International Managers' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the number of Initial
International Securities set forth opposite their respective names in Schedule
A hereto and not joint.

         SECTION 8.       Representations, Warranties and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company or any of its
subsidiaries submitted pursuant hereto, shall remain operative and in full
force and effect, regardless of any investigation made by or on behalf of any
International Manager or controlling person, or by or on behalf of the Company,
and shall survive delivery of the Securities to the International Managers.

         SECTION 9.       Termination of Agreement.

         (a)     Termination; General.  The Lead Managers may terminate this
Agreement, by notice to the Company, at any time at or prior to Closing Time
(i) if there has been, since the time of execution of this Agreement or since
the respective dates as of which information is given in the International
Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company, the Founding Companies and their subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
if there has occurred any material adverse





                                       20
<PAGE>   24
change in the financial markets in the United States or the international
financial markets, any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development involving a prospective change
in national or international political, financial or economic conditions, in
each case the effect of which is such as to make it, in the judgment of the
Lead Managers, impracticable to market the Securities or to enforce contracts
for the sale of the Securities, or (iii) if trading in any securities of the
Company has been suspended or materially limited by the Commission or the New
York Stock Exchange, or if trading generally on the American Stock Exchange or
the New York Stock Exchange or in the Nasdaq National Market has been suspended
or materially limited, or minimum or maximum prices for trading have been
fixed, or maximum ranges for prices have been required, by any of said
exchanges or by such system or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority, or
(iv) if a banking moratorium has been declared by either Federal or New York
authorities.

         (b)     Liabilities.  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that
Sections 1, 6, 7 and 8 shall survive such termination and remain in full force
and effect.

         SECTION 10.      Default by One or More of the International Managers.
If one or more of the International Managers shall fail at Closing Time or a
Date of Delivery to purchase the Securities which it or they are obligated to
purchase under this Agreement (the "Defaulted Securities"), the Lead Managers
shall have the right, within 24 hours thereafter, to make arrangements for one
or more of the non-defaulting International Managers, or any other
underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Lead Managers shall not have completed such
arrangements within such 24-hour period, then:

         (a)     if the number of Defaulted Securities does not exceed 10% of
the number of International Securities to be purchased on such date, each of
the non-defaulting International Managers shall be obligated, severally and not
jointly, to purchase the full amount thereof in the proportions that their
respective underwriting obligations hereunder bear to the underwriting
obligations of all non-defaulting International Managers, or

         (b)     if the number of Defaulted Securities exceeds 10% of the
number of International Securities to be purchased on such date, this Agreement
or, with respect to any Date of Delivery which occurs after the Closing Time,
the obligation of the International Managers to purchase and of the Company to
sell the Option Securities to be purchased and sold on such Date of Delivery
shall terminate without liability on the part of any non-defaulting
International Manager.

         No action taken pursuant to this Section shall relieve any defaulting
International Manager from liability in respect of its default.

         In the event of any such default which does not result in a
termination of this Agreement or, in the case of a Date of Delivery which is
after the Closing Time, which does not result in a termination of the
obligation of the International Managers to purchase and the Company to sell
the relevant International Option Securities, as the case may be, either the
Lead Managers or the Company shall have the right to postpone Closing Time or
the relevant Date of Delivery, as the case may be, for a period not exceeding
seven days in order to effect any required changes in the Registration
Statement or Prospectus or in any other documents or arrangements.  As used
herein, the term "International Manager" includes any person substituted for an
International Manager under this Section 10.

         SECTION 11.      Notices.  All notices and other communications
hereunder shall be in writing and shall be deemed to have been duly given if

the International Managers shall be directed to the Lead Managers at North
Tower, World Financial Center, New York, New York 10281-1201 attention of *;

         SECTION 12.      Parties.  This Agreement shall each inure to the
benefit of and be binding upon the International Managers and the Company and
their respective successors.  Nothing expressed or mentioned in this Agreement
is intended or shall be construed to give any person, firm or corporation,
other than the International Managers and the Company and their respective
successors and the controlling persons and officers and directors referred to
in Sections 6 and 7 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any

hereof are intended to be for the sole and exclusive benefit of the
International Managers and the Company and their respective successors, and
said controlling persons and officers and directors and their heirs and legal

a successor by reason merely of such purchase.

GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
SPECIFIED TIMES OF DAY IN THIS AGREEMENT REFER TO NEW YORK CITY TIME.

                      FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                SECTION 5(b)(i)

         (i)     The Company has been duly incorporated and is validly existing
as a corporation in good standing under the laws of the State of Delaware.

         (ii)    The Company has corporate power and authority to own, lease
and operate its properties and to conduct its business as described in the
Prospectuses and to enter into and perform its obligations under the U.S.
Purchase Agreement and the International Purchase Agreement.

         (iii)   The Company is duly qualified as a foreign corporation to
transact business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except where the failure so to qualify or
to be in good standing would not result in a Material Adverse Effect.

         (iv)    As of the Closing Time, the Company had authorized capital
stock consisting of 100,000,000 shares of Common Stock, par value $.01 per
share, and 10,000,000 shares of Preferred Stock, par  value $.01 per share (the
"Preferred Stock").  Prior to the closing of  the transactions contemplated by
each of the Acquisition Agreements and the issuance of shares of Common Stock
as contemplated thereby and by the U.S. Purchase Agreement and the
International Purchase Agreement, the Company had issued and outstanding
4,052,311 shares of Common Stock and no shares of Preferred Stock; upon
consummation of the Combination and the issuance of 12,313,026 shares of Common
Stock as contemplated by the Acquisition Agreements, (which, together with the
4,052,311 shares of Common Stock issued prior to the Combination, are all the
shares of Common Stock issued or to be issued prior to the issuance and sale of
the Securities), but without giving  effect to the issuance of the Securities
pursuant to the terms of the U.S. Purchase Agreement and the International
Purchase Agreement, the Company will have issued and outstanding 16,365,337
shares of Common Stock and no shares of Preferred Stock.   All of such shares
of Common Stock have been duly authorized and, when issued and delivered to the
purchasers thereof against payment therefor as provided in the Acquisition
Agreements, will be validly issued, fully paid and nonassessable.  None of the
outstanding shares of capital stock of the Company was issued in violation of
the preemptive or  other similar rights of any security holder of the Company.
Except as described in the Prospectuses, to our knowledge there are no
outstanding options, warrants or other rights calling for the issuance of, and
there are no commitments to issue any shares of, capital stock of the Company
or any security convertible into or exchangeable or exercisable for capital
stock of  the Company.

         (v)     The Securities to be purchased by the U.S. Underwriters and
the International Managers from the Company have been duly authorized for
issuance and sale to the Underwriters pursuant to the U.S. Purchase Agreement
and the International Purchase Agreement, respectively, and, when issued and
delivered by the Company pursuant to the U.S.  Purchase Agreement and the
International Purchase Agreement, respectively, against payment of the
consideration set forth in the U.S. Purchase Agreement and the





                                      A1-1
<PAGE>   32
International Purchase Agreement, will be validly issued and fully paid and
non-assessable and no holder of the Securities is or will be subject to
personal liability by reason of being such a holder.

         (vi)    The issuance of the Securities is not subject to the
preemptive or other similar rights of any security holder of the Company.

         (vii)   Each Acquisition Agreement has been duly and validly
authorized, executed and delivered by the Company and constitutes the valid and
binding obligation of each of the Company enforceable in accordance with its
terms, except as may be limited by bankruptcy, insolvency and other laws
affecting creditors' rights generally, or as may be modified by a court of
equity.

         (viii)  The transactions contemplated by each Acquisition Agreement
have been consummated as described in the Prospectuses.  As a result of the
Combination, all of the issued and outstanding capital stock or other equity
interest of each Founding Company and their subsidiaries is owned by the
Company, directly or through subsidiaries, free and clear of any security
interest, mortgage, pledge, lien, encumbrance, claim, shareholders agreement,
or voting trust, and no options, warrants or other rights to purchase,
agreements, or other obligations to issue or other rights to convert any other
obligations into shares of capital stock or ownership interests in any Founding
Company or any subsidiary thereof are outstanding.

         (ix)    The U.S. Purchase Agreement and the International Purchase
Agreement have been duly authorized, executed and delivered by the Company.

         (x)     The Registration Statement, including any Rule 462(b)
Registration Statement, has been declared effective under the 1933 Act; any
required filing of the Prospectuses pursuant to Rule 424(b) has been made in
the manner and within the time period required by Rule 424(b); and, to the best
of our knowledge, no stop order suspending the effectiveness of the
Registration Statement or any Rule 462(b) Registration Statement has been
issued under the 1933 Act and no proceedings for that purpose have been
instituted or are pending or threatened by the Commission.

         (xi)    The Registration Statement including any Rule 462(b)
Registration Statement and the Rule 430A Information, as applicable, the
Prospectuses and each amendment or supplement to the Registration Statement and
the Prospectuses as of their respective effective or issue dates (other than
the financial statements and supporting schedules included therein or omitted
therefrom, as to which we need express no opinion) complied as to form in all
material respects with the requirements of the 1933 Act and the 1933 Act
Regulations.

         (xii)   The form of certificate used to evidence the Common Stock
complies in all material respects with all applicable statutory requirements,
with any applicable requirements of the charter and by-laws of the Company and
the requirements of the New York Stock Exchange.

         (xiii)  To the best of our knowledge, there is not pending or
threatened any action, suit, proceeding, inquiry or investigation, to which the
Company or any Founding Company is a party, or to which the property of the
Company or any Founding Company is subject, before or brought by any court or
governmental agency or body, domestic or foreign, which might reasonably be
expected to result in a Material Adverse Effect, or which might reasonably be
expected to materially and adversely affect the properties or assets thereof or
the consummation of the transactions contemplated in the U.S. Purchase

Agreement, the International Purchase Agreement or the Acquisition Agreements
or the performance by the Company of its obligations thereunder.

         (xiv)   The information in the Prospectuses under the headings
"Management -- Employment Agreements," "--1997 Stock Plan," "--1997 Directors
Stock Plan;" "Certain Transactions;" "Description of Capital Stock," "Certain
United States Tax Considerations for Non-United States Holders" and "Shares
Eligible For Future Sale," and in the Registration Statement under Item 14, to
the extent that it constitutes matters of law, summaries of legal matters, the
Company's charter and bylaws or legal conclusions, has been reviewed by us  and
is correct in all material respects.

         (xv)    To the best of our knowledge, there are no statutes or
regulations that are required to be described in the Prospectuses that are not
described as required.

         (xvi)   All descriptions in the Prospectuses of contracts and other
documents to which the Company or any Founding Company is a party are accurate
in all material respects; to the best of our knowledge, there are no
franchises, contracts, indentures, mortgages, loan agreements, notes, leases or
other instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

         (xvii)  The Company is not in violation of its charter, by-laws or
other governing documents and, to our best knowledge, no default by the Company
exists in the due performance or observance of any material obligation,
agreement, covenant or condition contained in any contract, indenture,
mortgage, loan agreement, note, lease or other agreement or instrument that is
described or referred to in the Registration Statement or the Prospectuses or
filed or incorporated by reference as an exhibit to the Registration Statement.

         (xviii) No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign (other than under the 1933 Act and the
1933 Act Regulations, which have been obtained, or as may be required under the
securities or blue sky laws of the various states, as to which we express no
opinion) is necessary or required in connection with the due authorization,
execution and delivery of the U.S. Purchase Agreement and the International
Purchase Agreement or for the offering, issuance, sale or delivery of the
Securities.

         (xix)   No registration under the Act and no filing with, consent,
approval, authorization, order, registration or qualification of or with any
court or governmental agency or body is required for the issuance of the
Company Common Stock to the stockholders of each Founding Company pursuant to
the Acquisition Agreements or the consummation of the other transactions
contemplated by the Acquisition Agreements, except such filings, consents,
approvals, authorizations, registrations or qualifications as have been
obtained or made.

         (xx)    The execution, delivery and performance of the U.S. Purchase
Agreement and the International Purchase Agreement and the consummation of the
transactions contemplated in the U.S. Purchase Agreement, the International
Purchase Agreement and in the Registration Statement (including the issuance
and sale of the Securities, and the use of the proceeds from the sale of the
Securities as described in the Prospectuses under the caption "Use Of
Proceeds") and compliance by the Company with its obligations under the U.S.
Purchase Agreement and the International Purchase Agreement do not and will





                                      A1-3
<PAGE>   34
not, whether with or without the giving of notice or lapse of time or both,
conflict with or constitute a breach of, or default or Repayment Event (as
defined in Section 1(a)(x) of the Purchase Agreements) under or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Company or any Founding Company pursuant to any contract,
indenture, mortgage, deed of trust, loan or credit agreement, note, lease or
any other agreement or instrument, known to us, to which the Company or any
Founding Company is a party or by which it or any of them may be bound, or to
which any of the property or assets of the Company or any Founding Company is
subject (except for such conflicts, breaches or defaults or liens, charges or
encumbrances that would not have a Material Adverse Effect), nor will such
action result in any violation of the provisions of the charter, by-laws or
other governing documents of the Company or any Founding Company, or any
applicable law, statute, rule, regulation, judgment, order, writ or decree,
known to us, of any government, government instrumentality or court, domestic
or foreign, having jurisdiction over the Company or any Founding Company or any
of their respective properties, assets or operations.

         (xxi)   To the best of our knowledge, except as set forth in the
Prospectuses, there are no persons with registration rights or other similar
rights to have any securities registered pursuant to the Registration Statement
or otherwise registered by the Company under the 1933 Act.

         (xxii)  The Company is not, and will not be after consummation of the
Combination or application of the proceeds of the offering of the Securities as
set forth in the Prospectuses, an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the 1940
Act.

         Nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the Rule 430A
Information, (except for financial statements and schedules and other financial
data included therein or omitted therefrom, as to which we make no statement),
at the time such Registration Statement or any such amendment became effective,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading or that the Prospectuses or any amendment or supplement thereto
(except for financial statements and schedules and other financial data
included therein or omitted therefrom, as to which we make no statement), at
the time the Prospectuses were issued, at the time any such amended or
supplemented prospectus was issued or at the Closing Time, included or includes
an untrue statement of a material fact or omitted or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

         In rendering opinions set forth above with respect to matters
concerning the Founding Companies, such counsel may rely (A) as to matters
involving the application of the laws of the jurisdiction of incorporation or
organization of each Founding Company, upon the opinion of counsel to each
Founding Company (which opinion shall be dated and furnished to the U.S.
Representatives at the Closing Time, shall be satisfactory in form and
substance to counsel for the U.S.  Underwriters and shall expressly state that
the U.S. Underwriters may rely on such opinion as if it were addressed to
them), provided that such counsel shall state in their opinion that they
believe that they and the U.S. Underwriters are justified in relying upon such
opinion, and (B), as to matters of fact (but not as to legal conclusions), to
the extent they deem proper, on certificates of responsible officers of the
Company and public officials.  Such opinion shall not state that it is to be
governed or qualified by, or that it is otherwise subject to, any treatise,
written policy or other document relating to legal opinions, including, without
limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

                       FORM OF OPINION OF COUNSEL OF EACH
                                FOUNDING COMPANY
                  TO BE DELIVERED PURSUANT TO SECTION 5(b)(ii)

         (i)     Such Founding Company or any subsidiary thereof  that is a
corporation has been duly incorporated and is validly existing as a corporation
in good standing under the laws of the jurisdiction of its incorporation, has
corporate power and authority to own, lease and operate its properties and to
conduct its business as described in the Prospectuses and is duly qualified as
a foreign corporation to transact business and is in good standing in each
jurisdiction in which such qualification is required, whether by reason of the
ownership or leasing of property or the conduct of business, except where the
failure so to qualify or to be in good standing would not result in a Material
Adverse Effect.  None of the outstanding shares of capital stock of such
Founding Company or any subsidiary thereof was issued in violation of the
preemptive or similar rights of any security holder of such Founding Company or
subsidiary.  All of the issued and outstanding capital stock of such Founding
Company or any subsidiary thereof has been duly authorized and validly issued,
and is fully paid and non-assessable.   Such Founding Company or subsidiary
thereof that is a partnership or limited liability company has been duly formed
and is validly existing in good standing under the laws of the jurisdiction of
organization, has power and authority to own, lease and operate its properties
and to conduct its business as described in the Prospectuses and is duly
qualified to transact business and is in good standing in each jurisdiction in
which such qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except where the failure so to
qualify or to be in good standing would not result in a Material Adverse
Effect.

         (ii)    Each Acquisition Agreement has been duly and validly
authorized by such Founding Company and its shareholders and constitutes the
valid and binding obligation of such Founding Company and its shareholders
enforceable in accordance with its terms, except as may be limited by
bankruptcy, insolvency and other laws affecting creditors' rights generally, or
as may be modified by a court of equity.

         (iii)   Neither such Founding Company nor any subsidiary is in
violation of its charter, by-laws or other governing documents and, to the best
of our knowledge, no default by such Founding Company or any of its
subsidiaries exists in the due performance or observance of any material
obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described or referred to in the Registration Statement or
the Prospectuses or filed or incorporated by reference as an exhibit to the
Registration Statement.

         In rendering opinions set forth above, such counsel may rely as to
matters of fact (but not as to legal conclusions), to the extent they deem
proper, on certificates of responsible officers of the Founding Company and
public officials.  Such opinion shall not state that it is to be governed or
qualified by, or that it is otherwise subject to, any treatise, written policy
or other document relating to legal opinions, including, without limitation,
the Legal Opinion Accord of the ABA Section of Business Law (1991).

         meeting of stockholders of the Corporation.

                 Preferred Stock that is redeemed, purchased or retired by the
         Corporation shall, assume the status of authorized but unissued
         Preferred Stock and may thereafter, subject to the provisions of any
         Directors' Resolution providing for the issue of any particular series

         shares of any class or series of Preferred Stock as provided by the
         Board of Directors with respect to any such class or series of

         from time to time determine, payable to stockholders of record on such
         dates, not exceeding 60 days preceding the dividend payment dates, as
         shall be fixed for such purpose by the Board of Directors in advance of
         payment of each particular dividend.  All dividends on Common Stock
         shall be paid pari passu with dividends on Restricted Voting Common
         Stock.

                 In the event of any liquidation, dissolution or winding up of
         the Corporation, whether voluntary or involuntary, after the
         distribution or payment to the holders of shares of any class or
         series of Preferred Stock as provided by the Board of Directors with
         respect to any such class or series of Preferred Stock, the remaining
         assets of the Corporation available for distribution to stockholders
         shall be distributed among and paid to the holders of Common Stock and
         Restricted Voting Common Stock ratably in proportion to the number of
         shares of Common Stock and Restricted Voting Common Stock held by them
         respectively.

                 Except as otherwise required by law, each holder of shares of
         Common Stock shall be entitled to one vote for each share of Common
         Stock standing in such holder's name of the books of the Corporation.

                 (c)      Subject to the preferred rights of the holders of
         shares of any class or series of Preferred Stock as provided by the
         Board of Directors with respect to any such class or series of
         Preferred Stock, the holders of the Restricted Voting Common Stock
         shall be entitled to receive, as and when declared by the Board of
         Directors out of the funds of the Corporation legally available
         therefor, such dividends (payable in cash, stock or otherwise) as the
         Board of Directors may from time to time determine, payable to
         stockholders of record on such dates, not exceeding 60 days preceding
         the dividend payment dates, as shall be fixed for such purpose by the
         Board of Directors in advance of payment of each particular dividend.
         All dividends on Restricted Voting Common Stock shall be paid pari
         passu with dividends on Common Stock.

                 In the event of any liquidation, dissolution or winding up of
         the Corporation, whether voluntarily or involuntarily, after the
         distribution or payment to the holders of shares of any class or
         series of Preferred Stock as provided by the Board of Directors with
         respect to any such class or series of Preferred Stock, the remaining
         assets of the Corporation available for distribution to stockholders
         shall be distributed among and paid to the holders of Restricted
         Voting Common Stock and Common Stock ratably in proportion to the
         number of shares of Restricted Voting Common Stock and Common Stock
         held by them respectively.

         shall be entitled to elect one member of the Board of Directors, but
         shall not otherwise be entitled to vote in the election of directors
         of the Corporation.  Subject to the foregoing, and except as otherwise

         Restricted Voting Common Stock standing in such holder's name of the
         books of the Corporation.

                 Each share of the Restricted Voting Common Stock will
         automatically convert into Common Stock on a share-for-share basis (a)
         in the event of a disposition of such share of Restricted Voting
         Common Stock by the holder thereof (other than a disposition which is
         a distribution by a holder to its partners or beneficial owners or a
         transfer to a related party of such holder (as defined in Sections
         267, 707, 318 and/or 4946 of the Internal Revenue Code of 1986, as
         amended)), (b) in the event any person acquires beneficial ownership
         of 15% or more of the outstanding shares of Common Stock of the
         Corporation, or (c) in the event any person offers to acquire 15% or
         more of the outstanding shares of Common Stock of the Corporation.

                 After January 1, 2000, the Corporation may elect to convert
         any outstanding shares of Restricted Voting Common Stock into shares
         of Common Stock.

                 (d)      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 laws.

         5.      The Board of Directors is hereby authorized to create and
issue, whether or not in connection with the issuance and sale of any of its
stock or other securities, rights (the "Rights") entitling the holders thereof
to purchase from the Corporation shares of capital stock or other securities.
The times at which and the terms upon which the Rights are to be issued will be
determined by the Board of Directors and set forth in the contracts or
instruments that evidence the Rights.  The authority of the Board of Directors
with respect to the Rights shall include, but not be limited to, determination
of the following:





                                      -4-

                 (a)      The initial purchase price per share of the capital
         stock or other securities of the Corporation to be purchased upon
         exercise of the Rights;

                 (b)      Provisions relating to the times at which and the
         circumstances under which the Rights may be exercised or sold or
         otherwise transferred, either together with or separately from, any
         other securities of the Corporation;

                 (c)      Provisions that adjust the number or exercise price
         of the Rights or amount or nature of the securities or other property
         receivable upon exercise of the Rights in the event of a combination,
         split or recapitalization of any capital stock of the Corporation, a
         change in ownership of the Corporation's securities or a
         reorganization, merger, consolidation, sale of assets or other
         occurrence relating to the Corporation or any capital stock of the
         Corporation, and provisions restricting the ability of the Corporation
         to enter into any such transaction absent an assumption by the other
         party or parties thereto of the obligations of the Corporation under
         such Rights;

                 (d)      Provisions that deny the holder of a specified
         percentage of the outstanding securities of the Corporation the right
         to exercise the Rights and/or cause the Rights held by such holder to
         become void;

                 (e)      Provisions that permit the Corporation to redeem the
         Rights; and

                 (f)      The appointment of a Rights Agent with respect to the
         Rights;

         and such other provisions relating to the Rights as may be determined
by the Board of Directors.

         6.      No holder of stock of the Corporation shall be entitled as of
right to purchase or subscribe for any part of any unissued stock of the
Corporation or any additional stock to be issued whether or not by reason of
any increase of the authorized capital stock of the Corporation, or any bonds,
certificates of indebtedness, debentures or other securities convertible into
stock or such additional authorized issuance of new stock, but rather such
stock, bonds, certificates of indebtedness, debentures and other securities may
be issued and disposed of pursuant to resolution of the Board of Directors to
such persons, firms, corporations or associations, and upon such terms as may
be deemed advisable by the Board of Directors in the exercise of their
discretion.

         7.      The following provisions are inserted for the management of
the business and for the conduct of the affairs of the Corporation, and for
creating, defining, limiting and regulating the powers of the Corporation, the
directors and the stockholders.

                 (a)      Subject to any limitation contained in the bylaws,
         the Board of Directors may make bylaws, and from time to time may
         alter, amend or repeal any bylaws, but any bylaws made by the Board of
         Directors may be altered, amended or repealed by the stockholders at

<PAGE>   6
         any meeting of stockholders by the affirmative vote of the holders of
         at least 66 2/3% of the outstanding shares entitled to vote thereon,
         provided notice that an amendment is to be considered and acted upon
         is inserted in the notice of waiver of notice of such meeting.

                 (b)      Any vote or votes authorizing liquidation of the
         Corporation or proceedings for its dissolution may provide, subject to
         (i) any agreements among and between stockholders, (ii) the rights of
         creditors and (iii) rights expressly provided for particular classes
         or series of stocks, for the distribution pro rata among the
         stockholders of the Corporation of the assets of the Corporation,
         wholly or in part in kind, whether such assets be in cash or other
         property, and may authorize the Board of Directors of the Corporation
         to determine the value of the different assets of the Corporation for
         the purpose of such liquidation and may divide, such assets or any
         part thereof among the stockholders of the Corporation in such manner
         that every stockholder will receive a proportionate amount in value
         (determined as aforesaid) of cash or property of the Corporation upon
         such liquidation or dissolution even though each stockholder may not
         receive a strictly proportionate part of each such asset.

                 (c)      The Corporation shall, to the maximum extent
         permitted from time to time under the General Corporation Law of the
         State of Delaware, indemnify and upon request shall advance expenses
         to any person who is or was a party or is threatened to be made a
         party to any threatened, pending or completed action, suit, proceeding
         or claim, whether civil, criminal, administrative or investigative, by
         reason of the fact that he is or was or has agreed to be a director or
         officer of the Corporation, or while a director or officer 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 employee
         benefit plans, against expenses (including attorneys' fees and
         expenses), judgments, fines, penalties and amounts paid in settlement
         or incurred in connection with the investigation, preparation to
         defend or defense of such action, suit, proceeding or claim, whether
         civil, criminal, administrative or investigative, by reason of the
         fact that he is or was or has agreed to be a director or officer of
         the Corporation, or while a director or officer 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 employee benefit
         plans, against expenses (including attorneys' fees and expenses),

         in connection with the investigation, preparation to defend or defense
         of such action, suit, proceeding, claim or counterclaim initiated by
         or on behalf of such person.  Such indemnification shall not be
         exclusive of other indemnification rights arising under any bylaw,
         agreement, vote of directors or stockholders or otherwise and shall
         inure to the benefit of the heirs and legal representatives of such
         person.  Any repeal or modification of the foregoing provisions of
         this Section 7(c) shall be prospective only, and shall not adversely
         affect any right or protection of a director or officer of the
         Corporation existing at the time of such repeal or modification.

<PAGE>   7
                 (d)      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 General Corporation Law of the State of
         Delaware, or (iv) for any transaction from which the director derived
         an improper personal benefit.  If the General Corporation Law of the
         State of Delaware 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 General Corporation Law
         of the State of Delaware, as so amended.  Any repeal or modification
         of this Section by the stockholders of the Corporation shall be
         prospective only, and shall not adversely affect any limitation on the
         personal liability of a director of the Corporation existing at the
         time of such repeal or modification.

         8.      Subject to the rights of the holders of any class or series of
stock having a preference over the Common Stock as to dividends or upon
liquidation to elect additional directors under specific circumstances:

                 (a)      after March 1, 1998, any action required or permitted
         to be taken by the stockholders of the Corporation must be effected at
         a duly called annual or special meeting of stockholders of the
         Corporation and may not be effected by any consent in writing of such
         stockholders;

                 (b)      special meetings of the stockholders of the
         Corporation may be called only by the Chairman of the Board of
         Directors and shall be called within ten (10) days after receipt of
         the written request of the Board of Directors, pursuant to a
         resolution approved by a majority of the whole Board of Directors; and

                 (c)      the business permitted to be conducted at any special
         meeting of the stockholders is limited to the business brought before
         the meeting by the Chairman or by the Secretary at the request of a
         majority of the Board of Directors.

         9.      The number of directors which shall constitute the whole board
shall be such as from time to time shall be fixed by, or in the manner provided
in, the bylaws, but in no case shall the number be less than two nor more than
15.

         The directors shall be classified with respect to the time for which
they shall severally hold office by dividing them into three classes which
classes shall consist of an equal, or as near to equal as possible, number of
directors.  As to the initial election, the director or directors of the first
class shall be elected for a term expiring at the next annual meeting of
stockholders to be held in 1998; the director or directors of the second class
for a term expiring at the annual meeting to be held in 1999; and the director
or directors of the third class for a term expiring at the annual meeting to be





                                      -7-
<PAGE>   8
held in 2000.  At each annual meeting, commencing with the annual meeting in
1998, the successor or successors to the class of directors whose term shall
expire in that year shall be elected to hold office or the term of three years,
so that the term of office or one class of directors shall expire in each year.
Any increase or decrease in the number of directors constituting the Board
shall be apportioned among the classes so as to maintain the number of
directors in each class as near as possible to one-third the whole number of
directors as so adjusted.  Any director elected or appointed to fill a vacancy
shall hold office for the remaining term of the class to which such
directorship is assigned.  No decrease in the number of directors constituting
the Corporation's Board of Directors shall shorten the term of any incumbent
director.  Any vacancy in the Board of Directors, whether arising through
death, resignation or removal of a director, or through an increase in the
number of directors of any class, shall be filled by the majority vote of the
remaining directors, although less than a quorum, or by a sole remaining
director.  The bylaws may contain any provision regarding classification of the
Corporation's directors not inconsistent with the terms hereof.  The right to
cumulate votes in the election of directors is expressly prohibited.

                 A director of the Corporation may be removed only for cause
and only upon the affirmative vote of the holders of 66 2/3 percent of the
outstanding capital stock of the Corporation entitled to vote at an election of
directors, subject to further restrictions on removal, not inconsistent with
this Section 9, as may be contained in the bylaws.

                 Notwithstanding the foregoing, whenever the holders of any one
or more classes or series of Preferred Stock issued by the Corporation shall
have the right, voting separately by class or series, to elect directors at an
annual or special meeting of stockholders, the election, term of office,
filling of vacancies and other features of such directorships shall be governed
by the terms of the Directors' Resolutions applicable thereto, and such
directors so elected shall not be subject to the provisions of this Section 9
unless expressly provided by such terms.

                 Notwithstanding the foregoing, the holders of Restricted
Voting Common Stock voting as a class shall be entitled to elect one member of
the Board of Directors, and only the holders of the Restricted Voting Common
Stock shall be entitled to remove such member from the Board of Directors.

                 10.      Election of directors need not be by written ballot
unless the bylaws of the Corporation shall so provide.  Meetings of
stockholders 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
provisions contained in the statutes of the State of Delaware) outside the
State of Delaware at such place or places as may be designated from time to
time by the Board of Directors or the bylaws of the Corporation.

                 11.      The Corporation reserves the right to amend, alter,
change or repeal any provision contained in this Certificate of Incorporation
in the manner set forth below, and all rights and conferred upon the directors
or stockholders of the Corporation herein or in any amendment hereof are
granted subject to this reservation.

treated as votes cast.  The provisions of this paragraph will govern with
respect to all votes of stockholders except as otherwise provided for in these
Bylaws or in the certificate of incorporation or by a specific statutory
provision superseding the provisions contained in these Bylaws or the
certificate of incorporation.

such issue of a new certificate or certificates, the Board of Directors may, in
its discretion and as a condition precedent to the issuance thereof, require
the owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require

dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock
or for the purpose of any other lawful action, the Board of Directors may fix,
in advance, a record date, which shall not be more than sixty (60) nor less
than ten (10) days before the date of such meeting, nor more than sixty (60)
days prior to any other action.  A determination of stockholders of record

as amended from time to time, indemnify all officers and directors of the
Corporation whom it may indemnify pursuant thereto.  The provisions of this
Article IX shall apply to acts or omissions occurring before or after the
adoption hereof.  The right of indemnification herein provided for shall not be
exclusive of any other right to which any Director or officer may now or
hereafter be entitled under any statute, bylaw, agreement, vote of stockholders
or disinterested Directors or otherwise, shall continue as to a person who has
ceased to be such Director or officer entitled to indemnification pursuant to
this Article IX and shall inure to the benefit of the heirs, executors and

Houston, Texas 77003

Gentlemen:

                We have acted as counsel to Integrated Electrical Services,
Inc., a Delaware corporation (the "Company"), in connection with the
preparation of its Registration Statement on Form S-1 (Registration No.
333-38715) (the "Registration Statement"), filed by the Company under the
Securities Act of 1933, as amended (the "Securities Act"), with respect to the
offering and sale by the Company of up to 8,050,000 shares of its common stock,
par value $0.01 per share (the "Common Stock").  This opinion also relates to
any registration statement of the Company relating to the registration of
additional shares of Common Stock pursuant to Rule 462(b) under the Securities
Act.

                We have examined originals or copies of (i) the Amended and
Restated Certificate of Incorporation of the Company; (ii) the Bylaws of the
Company, as amended; (iii) certain resolutions of the Board of Directors and
the stockholders of the Company; and (iv) such other documents and records as
we have deemed necessary and relevant for purposes hereof.  We have relied upon
certificates of public officials and officers of the Company as to certain
matters of fact relating to this opinion and have made such investigations of
law as we have deemed necessary and relevant as a basis hereof.  We have not
independently verified any factual matter relating to this opinion.

                We have assumed the genuineness of all signatures, the
authenticity of all documents, certificates and records submitted to us as
copies, and the conformity to original documents, certificates and records of
all documents, certificates and records submitted to us as copies.

                Based upon the foregoing, and subject to the limitations and
assumptions set forth herein, and having due regard for such legal
considerations as we deem relevant, we are of the opinion that:

                1.      The Company is a corporation duly incorporated,
validly existing and in good standing under the laws of the State of Delaware.


                2.      The issuance of the Common Stock has been duly
authorized, and when issued and delivered by the Company against payment
therefor as described in the Registration Statement, such shares will be
validly issued, fully paid and nonassessable.

                The foregoing opinion is based on and is limited to the General
Corporation Law of the State of Delaware and the relevant laws of the United
States of America, and we render no opinion with respect to the laws of any
other jurisdiction.

                We hereby consent to the filing of this opinion with the
Securities and Exchange Commission as Exhibit 5.1 to the Registration Statement
and to the reference to this firm under the caption "Legal Matters" in the
prospectus contained in the Registration Statement.  By giving such consent, we
do not admit that we are included within the category of persons whose consent
is required under Section 7 of the Securities Act or the rules and regulations
issued thereunder.  This opinion may be incorporated by reference in a
registration statement of the Company relating to the registration of
additional shares of Common Stock pursuant to Rule 462(b) under the Securities
Act, in which case the opinions expressed herein will apply to the additional
shares registered thereunder.

                                                Very truly yours,

                                                /s/ Andrews & Kurth, L.L.P.

         fulfill all lawful policies established by the Company.

                 (c)      Except as set forth on Schedule 1(c) hereto,
         Executive shall not, during the term of his employment hereunder,
         engage in any other business activity pursued for gain, profit or
         other pecuniary advantage if such activity interferes in any material
         respect with Executive's duties and responsibilities hereunder.  The
         foregoing limitations shall not be construed as prohibiting Executive
         from making personal investments in such form or manner as will
         neither require his services in the operation or affairs of the
         companies or enterprises in which such investments are made nor
         violate the terms of paragraph 3 hereof.

                 (d)      Executive shall be entitled to vacation in accordance
         with the policies of the Company.

         2.      Compensation.  For all services rendered by Executive, the
Company shall compensate Executive as follows:

                 (a)      Base Salary.  The base salary payable to Executive
         during the term shall be $_____________________ per year, payable in
         accordance with the Company's payroll procedures for officers, but not
         less frequently than monthly.  Such base salary may be increased from
         time to time, at the discretion of the Board of Directors of IES (the
         "IES Board"), in light of the Executive's position, responsibilities
         and performance.

                 (b)      Executive Perquisites, Benefits and Other
         Compensation.  Executive shall be entitled to receive additional
         benefits and compensation from the Company in such form and to such
         extent as specified below:

                          (i)     Reimbursement for all business travel and
                 other out-of-pocket expenses (including those costs to
                 maintain any professional certifications held or obtained by
                 Executive) reasonably incurred by Executive in the performance
                 of his duties pursuant to this Agreement and in accordance
                 with the Company's policy for executives of the Company.  All
                 such expenses shall be appropriately documented in reasonable
                 detail by Executive upon submission of any request for
                 reimbursement, and in a format and manner consistent with the
                 Company's expense reporting policy.

                          (ii)    Executive shall, subject to the satisfaction
                 of any general eligible criteria, be eligible to participate
                 in all compensation and benefit plans and programs as are
                 maintained from time to time for executives of the Company.

                          (iii)   The Company shall provide Executive with such
                 other perquisites as may be deemed appropriate for Executive
                 by the IES Board.

                 3.       Non-Competition Agreement.

                 (a)      Executive recognizes that the Company's willingness
         to enter into this Agreement is based in material part on Executive's
         agreement to the provisions of this paragraph 3 and that Executive's
         breach of the provisions of this paragraph 3 could materially damage
         the Company.  Subject to the further provisions of this Agreement,
         Executive will not, during the term of his employment with the
         Company, and for a period of two years immediately following the
         termination of such for any reason whatsoever, either for Cause or in
         the event the Executive terminates his employment without Good Reason,
         except as may be set forth herein, directly or indirectly, for himself
         or on behalf of or in conjunction with any other person, company,
         partnership, corporation or business of whatever nature:

                          (i)     engage, as an officer, director, shareholder,
                 owner, partner, joint venturer, or in a managerial capacity,
                 whether as an employee, independent contractor, consultant or
                 advisor, or as a sales representative, in any electrical
                 contracting business in direct competition with any IES
                 Company within 100 miles of where any IES Company conducts
                 business, including any territory serviced by an IES Company
                 during the term of Executive's employment (the "Territory");

                          (ii)    call upon any person who is, at that time, an
                 employee of an IES Company for the purpose or with the intent
                 of enticing such employee away from or out of the employ of
                 the IES Company;

                          (iii)   call upon any person or entity which is, at
                 that time, or which has been, within one year prior to that
                 time, a customer of an IES Company within the Territory for
                 the purpose of soliciting or selling electrical contracting
                 products or services in direct competition with the IES
                 Companies within the Territory; or

                          (iv)    call upon any prospective acquisition
                 candidate, on Executive's own behalf or on behalf of any
                 competitor, which candidate was, to Executive's knowledge
                 after due inquiry, either called upon by an IES Company or for
                 which an IES Company made an acquisition analysis, for the
                 purpose of acquiring such entity.

                          (v)     disclose customers, whether in existence or
                 proposed, of the Company to any person, firm, partnership,
                 corporation or business for any reason or purpose whatsoever
                 except to the extent that the Company has in the past
                 disclosed such information to the public for valid business
                 reasons.

                 Notwithstanding the above, the foregoing covenant shall not be
         deemed to prohibit Executive from acquiring as an investment (i) not
         more than 1% of the capital stock of a





                                      -3-
<PAGE>   4


         competing  business, whose stock is traded on a national securities
         exchange, the Nasdaq Stock Market or on an over-the-counter or similar
         market or (ii) not more than 5% of the capital stock of a competing
         business whose stock is not publicly traded unless the Board of
         Directors of the Company consents to such acquisition.

                 (b)      Because of the difficulty of measuring economic
         losses to the Company and IES as a result of a breach of the foregoing
         covenant, and because of the immediate and irreparable damage that
         could be caused to the Company and IES for which they would have no
         other adequate remedy, Executive agrees that foregoing covenant may be
         enforced by the Company, in the event of breach by him, by injunctions
         and restraining orders.  Executive further agrees to waive any
         requirement for the Company's securing or posting of any bond in
         connection with such remedies.

                 (c)      It is agreed by the parties that the foregoing
         covenants in this paragraph 3 impose a reasonable restraint on
         Executive in light of the activities and business of the IES Companies
         on the date of the execution of this Agreement and the current plans
         of the IES Companies; but it is also the intent of the Company and
         Executive that such covenants be construed and enforced in accordance
         with the changing activities, business and locations of the IES
         Companies throughout the term of this covenant, whether before or
         after the date of termination of the employment of Executive, unless
         the Executive was conducting such new business prior to any IES
         Company conducting such new business.  For example, if, during the
         term of this Agreement, an IES Company engages in new and different
         activities, enters a new business or establishes new locations for its
         current activities or business in addition to or other than the
         activities or business enumerated under the Recitals above or the
         locations currently established therefor, then Executive will be
         precluded from soliciting the customers or employees of such new
         activities or business or from such new location and from directly
         competing with such new business within 100 miles of its
         then-established operating location(s) through the term of this
         covenant, unless the Executive was conducting such new business prior
         to any IES Company conducting such new business.

                 (d)      It is further agreed by the parties hereto that, in
         the event that Executive shall cease to be employed hereunder and
         shall enter into a business or pursue other activities not in
         competition with the electrical contracting activities of the IES
         Companies or similar activities or business in locations the operation
         of which, under such circumstances, does not violate clause (a)(i) of
         this paragraph 3, and in any event such new business, activities or
         location are not in violation of this paragraph 3 or of Executive's
         obligations under this paragraph 3, if any, Executive shall not be
         chargeable with a violation of this paragraph 3 if the IES Companies
         shall thereafter enter the same, similar or a competitive (i)
         business, (ii) course of activities or (iii) location, as applicable.





                                      -4-
<PAGE>   5



                 (e)      The covenants in this paragraph 3 are severable and
         separate, and the unenforceability of any specific covenant shall not
         affect the provisions of any other covenant.  Moreover, in the event
         any court of competent jurisdiction shall determine that the scope,
         time or territorial restrictions set forth are unreasonable, then it
         is the intention of the parties that such restrictions be enforced to
         the fullest extent which the court deems reasonable, and the Agreement
         shall thereby be reformed.

                 (f)      All of the covenants in this paragraph 3 shall be
         construed as an agreement independent of any other provision in this
         Agreement, and the existence of any claim or cause of action of
         Executive against the Company or IES, whether predicated on this
         Agreement or otherwise, shall not constitute a defense to the
         enforcement by IES or the Company of such covenants. It is
         specifically agreed that the period of two years (subject to the
         further provisions of this Agreement) following termination of
         employment stated at the beginning of this paragraph 3, during which
         the agreements and covenants of Executive made in this paragraph 3
         shall be effective, shall be computed by excluding from such
         computation any time during which Executive is in violation of any
         provision of this paragraph 3.

                 (g)      The Company and the Stockholders hereby agree that
         this covenant is a material and substantial part of this transaction.

         4.      Term; Termination; Rights on Termination.  The term of this
Agreement shall begin on the Effective Date and continue for five years (the
"Initial Term") and, unless terminated sooner as herein provided, shall
continue thereafter at Executive's and Company's mutual election on a
year-to-year basis on the same terms and conditions contained herein in effect
as of the time of renewal (the "Extended Term"); provided, however, upon a
Change in Control (as defined in paragraph 11(d)) the term of this Agreement
shall automatically continue following such Change in Control for a period
equal to the then remaining term or two years, whichever period is longer,
unless earlier terminated as provided in paragraph 11. This Agreement and
Executive's employment may be terminated in any one of the followings ways:

                 (a)      Death.  The death of Executive shall immediately
         terminate this Agreement with no severance compensation due to
         Executive's estate.

                 (b)      Disability.  If, as a result of incapacity due to
         physical or mental illness or injury, Executive shall have been absent
         from his full-time duties hereunder for four consecutive months, then
         30 days after receiving written notice (which notice may occur before
         or after the end of such four-month period, but which shall not be
         effective earlier than the last day of such four-month period), the
         Company may terminate Executive's employment hereunder, provided that
         Executive is unable to resume his full-time duties at the conclusion
         of such notice period.  Also, Executive may terminate his employment





                                      -5-
<PAGE>   6


         hereunder if his health should become impaired to an extent that makes
         the continued performance of his duties hereunder hazardous to his
         physical or mental health, provided that Executive shall have
         furnished the Company with a written statement from a doctor
         reasonably acceptable to the Company to such effect and provided,
         further, that, at the Company's request made within 30 days of the
         date of such written statement, Executive shall submit to an
         examination by a doctor selected by the Company who is reasonably
         acceptable to Executive or Executive's doctor and such second doctor
         shall have concurred in the conclusion of Executive's doctor.  In the
         event this Agreement is terminated as a result of Executive's
         disability, Executive shall receive from the Company, in a lump sum
         payment due within 10 days of the effective date of termination, the
         base salary at the rate then in effect (i) during the Initial Term,
         for whatever time period, if any, is remaining under the Initial Term,
         provided that such period shall not be less than one year, and (ii)
         during the Extended Term, equivalent to one year of base salary.

                 (c)      Cause.  The Company may terminate this Agreement and
         Executive's employment 10 days after written notice to Executive for
         "Cause", which shall be: (1) Executive's willful, material and
         irreparable breach of this Agreement (which remains uncured 10 days
         after receipt of written notice); (2) Executive's gross negligence in
         the performance or intentional nonperformance (in either case
         continuing for 10 days after receipt of written notice of need to
         cure) of any of Executive's material duties and responsibilities
         hereunder; (3) Executive's dishonesty or fraud with respect to the
         business, reputation or affairs of the Company or IES which materially
         and adversely affects the Company or IES (monetarily or otherwise); or
         (4) Executive's conviction of a felony crime involving moral
         turpitude.  In the event of a termination for Cause, Executive shall
         have no right to any severance compensation.

                 (d)      Without Cause.  Executive may, without Good Reason
         (as hereinafter defined) terminate this Agreement and Executive's
         employment, effective 30 days after written notice is provided to the
         Company.  Executive may only be terminated without Cause by the
         Company during either the Initial Term or Extended Term if such
         termination is approved by at least 51% of the members of the IES
         Board.  Should Executive be terminated by the Company without Cause or
         should Executive terminate with Good Reason during the Initial Term,
         Executive shall receive from the Company, in a lump sum payment due on
         the effective date of termination, the base salary at the rate then in
         effect for whatever time period is remaining under the Initial Term or
         for one year, whichever amount is greater.  Should Executive be
         terminated by the Company without Cause or should Executive terminate
         with Good Reason during the Extended Term, Executive shall receive
         from the Company, in a lump sum payment due on the effective date of
         termination, the base salary at the rate then in effect equivalent to
         one year of base salary.  Further, any termination without Cause by
         the Company or by Executive for Good Reason shall operate to shorten
         the period set forth in paragraph 3(a) and during which the terms of
         paragraph 3 apply to one





                                      -6-
<PAGE>   7


         year from the date of termination of employment.  If Executive resigns
         or otherwise terminates his employment without Good Reason, rather
         than the Company terminating his employment pursuant to this paragraph
         4(d), Executive shall receive no severance compensation.

                 Executive shall have "Good Reason" to terminate his employment
         hereunder upon the occurrence of any of the following events, unless
         such event is agreed to in writing by Executive:  (a) Executive is
         demoted by means of a material reduction in authority,
         responsibilities or duties to a position of less stature or importance
         within the Company than the position described in Section 1 hereof;
         (b) Executive's annual base salary as then in effect is reduced; or
         (c) the relocation of the Company's principal executive offices to a
         location outside the greater [____________________] area or the
         Company's requiring Executive to relocate anywhere other than the
         Company's principal executive offices.

         If termination of Executive's employment arises out of the Company's
failure to pay Executive on a timely basis the amounts to which he is entitled
under this Agreement or as a result of any other breach of this Agreement by
the Company, as determined by a court of competent jurisdiction or pursuant to
the provisions of paragraph 18 below, the Company shall pay all amounts and
damages to which Executive may be entitled as a result of such breach,
including interest thereon and all reasonable legal fees and expenses and other
costs incurred by Executive to enforce his rights hereunder.  Further, none of
the provisions of paragraph 3 shall apply in the event this Agreement is
terminated as a result of a breach by the Company.

         Upon termination of this Agreement for any reason provided above, in
addition to the above payments, if any, Executive shall be entitled to receive
all compensation earned and all benefits and reimbursements due through the
effective date of termination, paid to Executive in a lump sum on the effective
date.   All other rights and obligations of the Company and Executive under
this Agreement  shall cease as of the effective date of termination, except
that the Executive's obligations under paragraphs 3, 5, 6, 7, and 8 herein
shall survive such termination in accordance with their terms.

         5.      Return of Company Property.  All records, designs, patents,
business plans, financial statements, manuals, memoranda, lists and other
property delivered to or compiled by Executive by or on behalf of the Company,
IES or any IES Companies or their representatives, vendors or customers which
pertain to the business of the Company or IES or any IES Companies shall be and
remain the property of the Company or IES or the IES Company, as the case may
be, and be subject at all times to their discretion and control.  Likewise, all
correspondence, reports, records, charts, advertising materials and other
similar data pertaining to the business, activities or future plans of the
Company or IES or the IES Company which is collected by Executive shall be
delivered promptly to the Company without request by it upon termination of
Executive's employment.





                                      -7-
<PAGE>   8


         6.      Inventions.  Executive shall disclose promptly to the Company
any and all significant conceptions and ideas for inventions, improvements and
valuable discoveries, whether patentable or not, which are conceived or made by
Executive, solely or jointly with another, during the period of employment or
within one year thereafter, if conceived during employment, and which are
directly related to the business or activities of the Company and which
Executive conceives as a result of his employment by the Company.  Executive
hereby assigns and agrees to assign all his interests therein to the Company or
its nominee.  Whenever requested to do so by the Company, Executive shall
execute any and all applications, assignments or other instruments that the
Company shall deem necessary to apply for and obtain Letters Patent of the
United States or any foreign country or to otherwise protect the Company's
interest therein.

         7.      Trade Secrets.  Executive agrees that he will not, during or
after the term of this Agreement, disclose the specific terms of the Company's
or IES' relationships or agreements with their respective significant vendors
or customers or any other significant and material trade secret of the Company
or IES, whether in existence or proposed, to any person, firm, partnership,
corporation or business for any reason or purpose whatsoever.

         8.      Confidentiality.

                 (a)      Executive acknowledges and agrees that all
         Confidential Information (as defined below) of the Company is
         confidential and a valuable, special and unique asset of the Company
         that gives the Company an advantage over its actual and potential,
         current and future competitors.  Executive further acknowledges and
         agrees that Executive owes the Company a fiduciary duty to preserve
         and protect all Confidential Information from unauthorized disclosure
         or unauthorized use, that certain Confidential Information constitutes
         "trade secrets" under applicable laws and, that unauthorized
         disclosure or unauthorized use of the Company's Confidential
         Information would irreparably injure the Company.

                 (b)      Both during the term of Executive's employment and
         after the termination of Executive's employment for any reason
         (including wrongful termination), Executive shall hold all
         Confidential Information in strict confidence, and shall not use any
         Confidential Information except for the benefit of the Company, in
         accordance with the duties assigned to Executive.  Executive shall
         not, at any time (either during or after the term of Executive's
         employment), disclose any Confidential Information to any person or
         entity (except other employees of the Company who have a need to know
         the information in connection with the performance of their employment
         duties), or copy, reproduce, modify, decompile or reverse engineer any
         Confidential Information, or remove any Confidential Information from
         the Company's premises, without the prior written consent of the
         President of the Company, or permit any other person to do so.
         Executive shall take reasonable precautions to protect the physical
         security of all documents and other material containing Confidential
         Information (regardless of the medium on which the Confidential
         Information is stored).  This Agreement





                                      -8-
<PAGE>   9


         applies to all Confidential Information, whether now known or later to
         become known to Executive.

                 (c)      Upon the termination of Executive's employment with
         the Company for any reason, and upon request of the Company at any
         other time, Executive shall promptly surrender and deliver to the
         Company all documents and other written material of any nature
         containing or pertaining to any Confidential Information and shall not
         retain any such document or other material.  Within five days of any
         such request, Executive shall certify to the Company in writing that
         all such materials have been returned.

                 (d)      As used in this Agreement, the term "Confidential
         Information" shall mean any information or material known to or used
         by or for the Company (whether or not owned or developed by the
         Company and whether or not developed by Executive) that is not
         generally known to persons in the electrical contracting business.
         Confidential information includes, but is not limited to, the
         following: all trade secrets of the Company; all information that the
         Company has marked as confidential or has otherwise described to
         Executive (either in writing or orally) as confidential; all nonpublic
         information concerning the Company's products, services, prospective
         products or services, research, product designs, prices, discounts,
         costs, marketing plans, marketing techniques, market studies, test
         data, customers, customer lists and records, suppliers and contracts;
         all Company business records and plans; all Company personnel files;
         all financial information of or concerning the Company; all
         information relating to operating system software, application
         software, software and system methodology, hardware platforms,

         property; all technical specifications; any proprietary information
         belonging to the Company; all computer hardware or software manual;
         all training or instruction manuals; and all data and all computer
         system passwords and user codes.

         9.      No Prior Agreements.   Executive hereby represents and
warrants to the Company that the execution of this Agreement by Executive and
his employment by the Company and the performance of his duties hereunder will
not violate or be a breach of any agreement with a former employer, client or
any other person or entity.  Further, Executive agrees to indemnify the Company
for any claim, including, but not limited to, reasonable attorneys' fees and
expenses of investigation, by any such third party that such third party may
now have or may hereafter come to have against the Company based upon or
arising out of any non-competition agreement, invention or secrecy agreement
between Executive and such third party which was in existence as of the date of
this Agreement.

         10.     Assignment; Binding Effect.  Executive understands that he has
been selected for employment by the Company on the basis of his personal
qualifications, experience and skills.  Executive agrees, therefore, that he
cannot assign all or any portion of his performance under this





                                      -9-

Agreement.  Subject to the preceding two sentences and the express provisions
of paragraph 12 below, this Agreement shall be binding upon, inure to the
benefit of and be enforceable by the parties hereto and their respective heirs,
legal representatives, successors and assigns.

         11.     Change in Control.

                 (a)      Executive understands and acknowledges that the
         Company may be merged or consolidated with or into another entity and
         that such entity shall automatically succeed to the rights and
         obligations of the Company hereunder or that the Company may undergo a
         Change in Control (as defined below).  In the event a Change in
         Control is initiated or occurs during the Initial Term or Extended
         Term, then the provisions of this paragraph 11 shall be applicable.

                 (b)      In the event of a Change in Control wherein the
         Company and Executive have not received written notice at least ten
         business days prior to the date of the event giving rise to the Change
         in Control from the successor to all or a substantial portion of the
         Company's business and/or assets that such successor is willing as of
         the closing to assume and agrees to perform the Company's obligations
         under this Agreement in the same manner and to the same extent that
         the Company is hereby required to perform, then Executive may, at
         Executive's sole discretion, elect to terminate Executive's employment
         on such Change in Control by providing written notice to the Company
         prior to the closing of the transaction giving rise to the Change in
         Control.  In such case, the applicable provisions of paragraph 4(d)
         will apply as though the Company had terminated Executive without
         Cause; however, the amount of the lump sum severance payment due
         Executive shall be triple the amount calculated under the terms of
         paragraph 4(d), but shall in no event exceed nine times Executive's
         base salary.

                 (c)      In any Change in Control situation, Executive may, at
         Executive's sole discretion, elect to terminate Executive's employment
         upon the effective date of such Change in Control by providing written
         notice to the Company at least five business days prior to the closing
         of the transaction giving rise to the Change in Control.  In such
         case, the applicable provisions of paragraph 4(d) will apply as though
         the Company had terminated Executive without Cause; however, the
         amount of the lump sum severance payment due Executive shall be double
         the amount calculated under the terms of paragraph 4(d), but shall in
         no event exceed six times Executive's base salary.

                 (d)      If, on or within two years following the effective
         date of a Change in Control the Company terminates Executive's
         employment other than for Cause or Executive terminates his employment
         for Good Reason, or if Executive's employment with the Company is
         terminated by the Company within three months before the effective
         date of a Change in Control and it is reasonably demonstrated that
         such termination (i) was at the





                                      -10-
<PAGE>   11


         request of a third party that has taken steps reasonably calculated to
         effect a Change in Control, or (ii) otherwise arose in connection with
         or anticipation of a Change in Control, then Executive shall receive
         from Company, in a lump sum payment due on the effective date of
         termination, the greater of (i) the equivalent of three years' base
         salary at the rate then in effect, or (ii) the base salary for
         whatever period is then remaining on the Initial Term, if any.

                 (e)      A "Change in Control" shall be deemed to have
         occurred if:

                          (i)     any person, entity or group (as such terms
                 are used in Sections 13(d) and 14(d)(2) of the Securities
                 Exchange Act of 1934, as amended (the "Act"), other than the
                 IES Companies or an employee benefit plan of the IES
                 Companies, acquires, directly or indirectly, the beneficial
                 ownership (as defined in Section 13(d) of the Act) of any
                 voting security of IES and immediately after such acquisition
                 such person is, directly or indirectly, the beneficial owner
                 of voting securities representing 20% or more of the total
                 voting power of all of the then outstanding voting securities
                 of IES entitled to vote generally in the election of
                 directors;

                          (ii)    upon the first purchase of IES's common stock
                 pursuant to a tender or exchange offer (other than a tender or
                 exchange offer made by IES);

                          (iii)   the stockholders of IES shall approve a
                 merger, consolidation, recapitalization or reorganization of
                 IES, or a reverse stock split of outstanding voting
                 securities, or consummation of any such transaction if
                 stockholder approval is not obtained, other than any such
                 transaction which would result in at least 75% of the total
                 voting power represented by the voting securities of the
                 surviving entity outstanding immediately after such
                 transaction being beneficially owned by the holders of all of
                 the outstanding voting securities of IES immediately prior to
                 the transactions with the voting power of each such continuing
                 holder relative to other such continuing holders not
                 substantially altered in the transaction;

                          (iv)    the stockholders of IES shall approve a plan
                 of complete liquidation or dissolution of IES or an agreement
                 for the sale or disposition by IES of all or substantially all
                 of IES's assets; or

                          (v)     if, at any time during any period of two
                 consecutive years, individuals who at the beginning of such
                 period constitute the Board cease for any reason to constitute
                 at least a majority thereof, unless the election or nomination
                 for the election by the Company's stockholders of each new
                 director was approved by a vote of at least two-thirds of the
                 directors then still in office who were directors at the
                 beginning of the period.

                 (f)      Notwithstanding anything in this Agreement to the
         contrary, a termination pursuant to paragraph 11(b), (c), or (d) shall
         operate to automatically waive in full the noncompetition restrictions
         imposed on Executive pursuant to paragraph 3(a).

                 (g)      If it shall be finally determined that any payment
         made or benefit provided to Executive in connection with a "change in
         control" of the Company or IES, whether or not made or provided
         pursuant to this Agreement, is subject to the excise tax imposed by
         Section 4999 of the Internal Revenue Code of 1986, as amended, or any
         successor thereto, the Company shall pay Executive an amount of cash
         (the "Additional Amount") such that the net amount received by
         Executive after paying all applicable taxes on such Additional Amount
         shall be equal to the amount that Executive would have received if
         Section 4999 were not applicable.

         12.     No Mitigation or Offset.  Executive shall not be required to
mitigate the amount of any Company payment provided for in this Agreement by
seeking other employment or otherwise.  The amount of any payment required to
be paid to Executive by the Company pursuant to this Agreement shall not be
reduced by any amounts that are owed to the Company by Executive, or by any
setoff, counterclaim, recoupment, defense or other claim, right or action.

         13.     Release.  Notwithstanding anything in this Agreement to the
contrary, Executive shall not be entitled to receive any payments pursuant to
this Agreement unless Executive has executed (and not revoked) a general
release of all claims Executive may have against the Company and its affiliates
in a form of such release reasonably acceptable to the Company.

         14.     Indemnification.  In the event Executive is made a party to
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by the Company
against Executive), by reason of the fact that he is or was performing services
under this Agreement, then the Company shall indemnify Executive against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, as actually and reasonably incurred by Executive in connection
therewith.  In the event that both Executive and the Company are made a party
to the same third-party action, complaint, suit or proceeding, the Company
agrees to engage competent legal representation, and Executive agrees to use
the same representation, provided that if counsel selected by the Company shall
have a conflict of interest that prevents such counsel from representing
Executive, Employee may engage separate counsel and the Company shall pay all
attorneys' fees and reasonable expenses of such separate counsel.  Further,
while Executive is expected at all times to use his best efforts to faithfully
discharge his duties under this Agreement, Executive cannot be held liable to
the Company for errors or omissions made in good faith where Executive has not
exhibited gross, willful and wanton negligence and misconduct nor performed
criminal and fraudulent acts which materially damage the business of the
Company.

         15.     Complete Agreement. Executive has no oral representations,
understandings or agreements with the Company, IES or any of their officers,
directors or representatives covering the same subject matter as this
Agreement.  This written Agreement is the final, complete and exclusive
statement and expression of the agreement between the Company, IES and
Executive and of all the terms of this Agreement, and it cannot be varied,
contradicted or supplemented by evidence of any prior or contemporaneous oral
or written agreements.  This written Agreement may not be later modified except
by a further writing signed by a duly authorized officer of the Company and
Executive, and no term of this Agreement may be waived except by writing signed
by the party waiving the benefit of such term.  Without limiting the generality
of the foregoing, either party's failure to insist on strict compliance with
this Agreement shall not be deemed a waiver thereof.

         16.     Notice. Whenever any notice is required hereunder, it shall be
given in writing addressed as follows:

         To the Company:          c/o Integrated Electrical Services, Inc.

such change in accordance with this paragraph 16.

         17.     Severability; Headings.  If any portion of this Agreement is

deemed valid and operative and, so far as is reasonable and possible, effect
shall be given to the intent manifested by the portion held invalid or
inoperative.  The paragraph headings herein are for reference purposes only and

If the parties do not promptly agree on a mediator, the parties shall request
the Association of Attorney Mediators in Harris County, Texas to appoint a
mediator certified by the Supreme Court of Texas.  If the mediator is unable to
facilitate a settlement of the dispute within a reasonable period of time, as
determined by the mediator, the mediator shall issue a written statement to the
parties to that effect and any unresolved dispute or controversy arising under

arbitration, conducted before a panel of three arbitrators in Houston, Texas,
in accordance with the rules of the American Arbitration Association then in
effect.  The arbitrators shall have the authority to order back-pay, severance
compensation, vesting of options (or cash compensation in lieu of vesting of
options), reimbursement of costs, including those incurred to enforce this
Agreement, and interest thereon in the event the arbitrators determine that
Executive was terminated without disability or Cause, as defined in paragraphs
4(b) and 4(c), respectively, or that the Company has otherwise materially
breached this Agreement.  A decision by a majority of the arbitration panel
shall be final and binding.  Judgment may be entered on the arbitrators' award
in any court having jurisdiction.  The costs and expenses, including reasonable
attorneys' fees, of the prevailing party in any dispute arising under this
Agreement will be promptly paid by the other party.

         19.     Governing Law.  This Agreement shall in all respects be

conflicts of law provisions.

         20.     Counterparts.  This Agreement may be executed simultaneously
in two or more counterparts, each of which shall be deemed an original and all
of which together shall constitute but one and the same instrument.


         IN WITNESS WHEREOF, the parties hereto have executed this Agreement
effective for all purposes as of the Effective Date.

         WHEREAS, the certificate of incorporation and bylaws of the Company
provide for the indemnification of the Company's directors and executive

and, along with the Delaware General Corporation Law, contemplate that the
Company may enter into agreements with respect to such indemnification; and

         WHEREAS, the Board of Directors of the Company has concluded that it
is reasonable, prudent and in the best interests of the Company's stockholders
for the Company to contractually obligate itself to indemnify certain of its
Authorized Representatives (defined below) so that they will serve or continue
to serve with greater certainty that they will be adequately protected.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company and Indemnitee hereby agree as follows:

         1.      Definitions.  For purposes of this Agreement, except as
otherwise expressly provided or unless the context otherwise requires, the
following terms shall have the following respective meanings:

         or proceeding (whether formal or informal, or civil, criminal,
         administrative, legislative, arbitrative or investigative) in respect
         of which Indemnitee is, was or at any time becomes, or is threatened
         to be made, a party, witness, subject or target, by reason of the fact

                 (iii)    the words "herein," "hereof" and "hereunder" and

                 (iv)     unless the context indicates otherwise, reference to
         any Section means such Section hereof; and

similar matter involving the interpretation or meaning of this Agreement, this

provisions of this Agreement, that provision providing the most comprehensive
indemnification shall apply.

as a director of the Company, provided that the foregoing shall not eliminate
or limit the liability of Indemnitee (i) for any breach of Indemnitee's duty of
loyalty to the Company 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 relating
to unlawful dividend payments and unlawful stock purchases or redemptions or
(iv) for any transaction from which Indemnitee derived an improper personal
benefit.

         4.      Indemnity.  (a)  Subject to the following provisions of this
Agreement, the Company shall hold harmless and indemnify Indemnitee against all
Expenses and Liabilities actually incurred by Indemnitee in connection with any
Proceeding; provided, however, that no indemnity shall be paid by the Company
pursuant to this Agreement:

                 (i)      for amounts actually paid to Indemnitee pursuant to
         one or more policies of directors and officers liability insurance
         maintained by the Company or pursuant to a trust fund, letter of
         credit or other security or funding arrangement provided by the
         Company; provided, however, that if it should subsequently be
         determined that Indemnitee is not entitled to retain any such amount,
         this clause (i) shall no longer apply to such amount;

                 (ii)     in respect of remuneration paid to Indemnitee if it
         shall be determined by a final judgment or other final adjudication
         that payment of such remuneration was in violation of applicable law;

                 (iii)    on account of Indemnitee's conduct which is finally
         adjudged to constitute willful misconduct or to have been knowingly
         fraudulent, deliberately dishonest or from which the Indemnitee
         derives an improper personal benefit; or

                 (iv)     on account of any suit in which final judgment is
         rendered against Indemnitee for an accounting of profits made from the
         sale or purchase by Indemnitee of securities of the Company pursuant
         to the provisions of Section 16(b) of the Securities Exchange Act of
         1934, as amended.

         (b)     If Indemnitee is entitled under any provision of this
Agreement to indemnification by the Company for only a portion (but not,
however, for the total amount) of any Expenses or Liabilities actually incurred
by Indemnitee in connection with any Proceeding, the Company shall nevertheless
indemnify Indemnitee for the portion of such Expenses and Liabilities to which
Indemnitee is entitled.  If the indemnification provided for herein in respect
of any Expenses or Liabilities actually incurred by Indemnitee in connection
with any Proceeding is finally determined by a court of competent jurisdiction
to be prohibited by applicable law, then the Company, in lieu of indemnifying
Indemnitee, shall contribute to the amount paid or payable by Indemnitee as a
result of such Expenses and Liabilities in such proportion as is appropriate to
reflect (i) the relative benefits received by the Company on the one hand and
Indemnitee on the other hand from the events, circumstances, conditions,
happenings, actions or transactions from which such Proceeding arose, (ii) the
relative fault of the Company (including its other Authorized Representatives)
on the one hand and of Indemnitee on the other hand in connection with the
events,





                                      -3-
<PAGE>   4
circumstances and happenings which resulted in such Expenses and Liabilities,
such relative fault to be determined by reference to, among other things, the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent the events, circumstances and/or happenings resulting in
such Expenses and Liabilities, and (iii) any other relevant equitable
considerations, it being agreed that it would not be just and equitable if such
contribution were determined by pro rata or other method of allocation which
does not take into account the foregoing equitable considerations.

         (c)     The indemnification provided herein shall be applicable only
to Proceedings commenced after the date hereof, regardless, however, of whether
they arise from acts, omissions, facts or circumstances occurring before or
after the date hereof.

         (d)     The indemnification provided herein shall be applicable
whether or not negligence of Indemnitee is alleged or proved, and regardless of
whether such negligence be contributory or sole.

         (e)     Amounts paid by the Company to Indemnitee under this Section 4
are subject to refund by Indemnitee as provided in Section 8.

         5.      Notification and Defense of Claims.  (a)  Promptly after the
receipt by Indemnitee of notice of the commencement of any Proceeding,
Indemnitee will, if a claim in respect thereof is to be made against the
Company under this Agreement, notify the Company of the commencement of such
Proceeding; provided, however, that the omission to so notify the Company will
not relieve the Company (i) from any liability which it may have to Indemnitee
under this Agreement unless, and then only to the extent that, such omission
results in insufficient time being available to permit the Company or its
counsel to effectively defend against or make timely response to any loss,
claim, damage, liability or expense resulting from such Proceeding or otherwise
has a material adverse effect on the Company's ability to promptly deal with
such loss, claim, damage, liability or expense or (ii) from any liability which
it may have to Indemnitee otherwise than under this Agreement.

         (b)     The following provisions shall apply with respect to any such
Proceeding as to which Indemnitee notifies the Company of the commencement
thereof:

                 (i)      The Company shall be entitled to participate therein
         at its own expense.

                 (ii)     Except as otherwise provided below, to the extent it
         may elect to do so, the Company (jointly with any other indemnifying
         party similarly notified) will be entitled to assume the defense
         thereof, with counsel of its own selection reasonably satisfactory to
         Indemnitee.  After notice from the Company to Indemnitee of its
         election so to assume the defense thereof, the Company will not be
         liable to Indemnitee under this Agreement for any Expenses
         subsequently incurred by Indemnitee in connection with the defense of
         such Proceeding other than reasonable costs of investigation or as
         otherwise provided below.  Indemnitee shall have the right to employ
         separate counsel in such





                                      -4-
<PAGE>   5
         Proceeding but the fees and expenses of such counsel incurred after
         notice from the Company of its assumption of the defense thereof shall
         be at the expense of Indemnitee unless (1) the employment of separate
         counsel by Indemnitee has been authorized by the Company; (2)
         Indemnitee shall have reasonably concluded that there may be a
         conflict of interest between the Company and Indemnitee in the conduct
         of the defense of such Proceeding; or (3) the Company shall not in
         fact have employed counsel to assume the defense of such Proceeding,
         in each of which cases the reasonable fees and expenses of
         Indemnitee's counsel shall be borne by the Company.  The Company shall
         not be entitled to assume the defense of any Proceeding brought by or
         on behalf of the Company or as to which Indemnitee shall have made the
         conclusion provided for in (2) above.  Nothing in this subparagraph
         (ii) shall affect the obligation of the Company to indemnify
         Indemnitee against Expenses and Liabilities paid in settlement for
         which it is otherwise obligated hereunder.

                 (iii)    The Company shall not be liable to indemnify
         Indemnitee under this Agreement for any amounts paid in settlement of
         any Proceedings or claims effected without its prior written consent.
         The Company shall not settle any Proceeding or claim in any manner
         which would impose any penalty or limitation on Indemnitee without
         Indemnitee's prior written consent.  Neither the Company nor
         Indemnitee will unreasonably withhold or delay its consent to any
         proposed settlement.

         6.      Advancement of Expenses, etc.  If requested to do so by
Indemnitee with respect to any Proceeding, the Company shall advance to or for
the benefit of Indemnitee, prior to the final disposition of such Proceeding,
the Expenses actually incurred by Indemnitee in investigating, defending or
appealing such Proceeding.  Any judgments, fines or amounts to be paid in
settlement of any Proceeding shall also be advanced by the Company upon request
by Indemnitee.  Advances made by the Company under this Section 6 are subject
to refund by Indemnitee as provided in Section 8.

         7.      Right of Indemnitee to Bring Suit.  (a)  If a claim for
indemnification or a claim for an advance under this Agreement is not paid in
full by the Company within 30 days after receipt by the Company from Indemnitee
of a written request or demand therefor, Indemnitee may bring suit against the
Company to recover the unpaid amount of the claim.  If, in any such action,
Indemnitee makes a prima facie showing of entitlement to indemnification under
this Agreement, the Company shall have the burden of proving that
indemnification is not required under this Agreement.  The only defense to any
such action shall be that indemnification is not required by this Agreement.

         (b)     In the event that any action is instituted by Indemnitee to
enforce Indemnitee's rights or to collect monies due to Indemnitee under this
Agreement and if Indemnitee is successful in such action, the Company shall
reimburse Indemnitee for all Expenses incurred by Indemnitee with respect to
such action.





                                      -5-
<PAGE>   6
         8.      Repayment Obligation of Indemnitee.  If the Company advances
or pays any amount to Indemnitee under Section 4, 6 or 7 and if it shall
thereafter be finally adjudicated that Indemnitee was not entitled to be
indemnified hereunder for all or any portion of such amount, Indemnitee shall
promptly repay such amount or such portion thereof, as the case may be, to the
Company.  If the Company advances or pays any amount to Indemnitee under
Section 4, 6 or 7 and if Indemnitee shall thereafter receive all or a portion
of such amount under one or more policies of directors and officers liability
insurance maintained by the Company or pursuant to a trust fund, letter of
credit or other security or funding arrangement provided by the Company,
Indemnitee shall promptly repay such amount or such portion thereof, as the
case may be, to the Company.

         9.      Changes in Law.  If any change after the date of this
Agreement in any applicable law, statute or rule expands the power of the
Company to indemnify Authorized Representatives, such change shall be within
the purview of Indemnitee's rights and the Company's obligations under this
Agreement.  If any  change after the date of this Agreement in any applicable
law, statute or rule narrows the right of the Company to indemnify an
Authorized Representative, such change shall, to the fullest extent permitted
by applicable law, leave this Agreement and the parties' rights and obligations
hereunder unaffected.

         10.     Continuation of Indemnity.  All agreements and obligations of
the Company hereunder shall continue during the period Indemnitee is an
Authorized Representative, and shall continue after Indemnitee has ceased to
occupy such position or have such relationship so long as Indemnitee shall be
subject to any possible Proceeding.

         11.     Nonexclusivity.  The indemnification and other rights provided
by any provision of this Agreement shall not be deemed exclusive of any other
rights to which Indemnitee may be entitled under (i) any statutory or common
law, (ii) the Company's certificate of incorporation, (iii) the Company's
bylaws, (iv) any other agreement or (v) any vote of stockholders or
disinterested directors or otherwise, both as to action in Indemnitee's
official capacity and as to action in another capacity while occupying any of
the positions or having any of the relationships referred to in this Agreement.
Nothing in this Agreement shall in any manner affect, impair or compromise any
indemnification Indemnitee has or may have by virtue of any agreement
previously entered into between Indemnitee and the Company.

         12.     Severability.  If any provision of this Agreement shall be
held to be invalid, illegal or unenforceable (i) the validity, legality or
enforceability of the remaining provisions of this Agreement shall not be in
any way affected or impaired thereby and (ii) to the fullest extent possible,
the provisions of this Agreement shall be construed so as to give effect to the
intent manifested by the provision held invalid, illegal or unenforceable.
Each provision of this Agreement is a separate and independent portion of this
Agreement.

         13.     Modification and Waiver.  No supplement, modification or
amendment of this Agreement shall be binding unless executed in writing by both
of the parties.  No waiver of any of





                                      -6-
<PAGE>   7
the provisions of this Agreement shall be binding unless executed in writing by
the person making the waiver nor shall such waiver constitute a continuing
waiver.

         14.     Notices.  All notices, requests, demands and other
communications hereunder shall be in writing and shall be addressed (i) if to
the Company, at its principal office address as shown on the signature page
hereof or such other address as it may have designated by written notice to
Indemnitee for purposes hereof, directed to the attention of the Secretary and
(ii) if to Indemnitee, at Indemnitee's address as shown on the signature page
hereof or to such other address as Indemnitee may have designated by written
notice to the Company for purposes hereof.  Each such notice or other
communication shall be deemed to have been duly given if (a) delivered by hand
and receipted for by the party to whom said notice or other communication shall
have been directed, (b) transmitted by facsimile transmission, at the time that
receipt of such transmission is confirmed, or (c) mailed by certified or
registered mail with postage prepaid, on the third business day after the date
on which it is so mailed.

         15.     Governing Law.  THIS AGREEMENT SHALL BE DEEMED TO BE A
CONTRACT MADE UNDER, AND SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF TEXAS WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW.

         16.     Heirs, Successors and Assigns.  (a)  This Agreement shall be
binding upon, inure to the benefit of and be enforceable by (i) Indemnitee and
Indemnitee's personal or legal representatives, executors, administrators,
heirs, devisees and legatees and (ii) the Company and its successors and
assigns.  This Agreement shall not inure to the benefit of any other person or
Enterprise.

         (b)     The Company agrees to require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place.  As used herein, the term "Company" shall include any
successor to its business and/or assets as aforesaid which executes and
delivers the assumption and agreement provided for in this Section 16 or which
otherwise becomes bound by all terms and provisions of this Agreement by
operation of law.

the Company, subject to such limitations on such delegated powers and duties as
the Committee may impose.  Upon any such delegation all references in the Plan

suspended and the method or methods by which Awards may be settled, exercised
canceled, forfeited, or suspended; (vi) determine whether, to what extent, and

property, and other amounts payable with respect to an Award shall be deferred
either automatically or at the election of the holder thereof or of the
Committee; (vii) interpret and administer the Plan and any instrument or
agreement relating to an Award made under the Plan; (viii) establish, amend,
suspend, or waive such rules and regulations and appoint such agents as it
shall deem appropriate for the proper administration of the Plan; and (ix) make
any other determination and take any other action that the Committee deems
necessary or desirable for the administration of the Plan.  Unless otherwise
expressly provided in the Plan, all designations, determinations,
interpretations, and other decisions under or with respect to the Plan or any
Award shall be within the sole discretion of the Committee, may be made at any

to more than 1,000,000 Shares. If any Award is forfeited or otherwise
terminates or is canceled without the delivery of Shares or other
consideration, then the Shares covered by such Award, to the extent of such
forfeiture, termination or cancellation, shall again be Shares with respect to
which Awards may be granted.

         (b)     Sources of Shares Deliverable Under Awards.  Any Shares
delivered pursuant to an Award may consist, in whole or in part, of authorized
and unissued Shares or of treasury Shares.

         (c)     Adjustments.  In the event that the Committee determines that
any dividend or other distribution (whether in the form of cash, Shares, other
securities, or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Shares or other securities of the Company, issuance
of warrants or other rights to purchase Shares or other securities of the
Company, or other similar corporate transaction or event affects the Shares
such that an adjustment is determined by the Committee to be appropriate in
order to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, then the Committee shall, in such
manner as it may deem equitable, adjust any or all of (i) the number and type
of Shares (or other securities or property) with respect to which Awards may be
granted, (ii) the number and type of Shares (or other securities or property)
subject to outstanding Awards, and (iii) the grant or exercise price with
respect to any Award or, if deemed appropriate, make provision for a cash
payment to the holder of an outstanding Award; provided, in each case, that
with respect to Awards of Incentive Stock Options and Awards intended to
qualify





                                      -4-
<PAGE>   5
as performance based compensation under Section 162(m)(4)(C) of the Code, no
such adjustment shall be authorized to the extent that such authority would
cause the Plan to violate Section 422(b)(1) of the Code or would cause such
Award to fail to so qualify under Section 162(m) of the Code, as the case may
be, or any successor provisions thereto; and provided, further, that the number
of Shares subject to any Award denominated in Shares shall always be a whole
number.

         SECTION 5.   Eligibility.

         Any Employee and Consultant shall be eligible to be designated a
Participant.  However, no Employee or Consultant may receive Options and/or
Stock Appreciation Rights with respect to more than 250,000 Shares during any
calendar year.  The maximum amount of compensation that may be paid to any
Participant with respect to any single Award that is not an Option or Stock
Appreciation and which is intended to qualify as "performance based"
compensation under Section 162(m) of the Code in any calendar year shall not
exceed $4.0 million, determined as of the date of grant of such Award.

         SECTION 6.   Awards.

         (a)     Options.  Subject to the provisions of the Plan, the Committee
shall have the authority to determine the Participants to whom Options shall be
granted, the number of Shares to be covered by each Option, the purchase price
therefor and the conditions and limitations applicable to the exercise of the
Option, including the following terms and conditions and such additional terms
and conditions, as the Committee shall determine, that are not inconsistent
with the provisions of the Plan.

                 (i)      Exercise Price.  The purchase price per Share
         purchasable under an Option shall be determined by the Committee at
         the time the Option is granted.

                 (ii)     Time and Method of Exercise.  The Committee shall
         determine the time or times at which an Option may be exercised in
         whole or in part, and the method or methods by which, and the form or
         forms (which may include, without limitation, cash, check acceptable
         to the Company, Shares already-owned for more than six months,
         outstanding Awards, Shares that would otherwise be acquired upon
         exercise of the Option, a "cashless-broker" exercise (through
         procedures approved by the Company), other securities or other
         property, or any combination thereof, having a Fair Market Value on
         the exercise date equal to the relevant exercise price) in which
         payment of the exercise price with respect thereto may be made or
         deemed to have been made.

                 (iii)    Incentive Stock Options.  The terms of any Incentive
         Stock Option granted under the Plan shall comply in all respects with
         the provisions of Section 422 of the Code, or any successor provision,
         and any regulations promulgated thereunder.  Incentive Stock Options
         may be granted only to employees of the Company and its parent
         corporation and subsidiary corporations, within the meaning of Section
         424 of the Code.





                                      -5-
<PAGE>   6
         (b)     Stock Appreciation Rights.  Subject to the provisions of the
Plan, the Committee shall have the authority to determine the Participants to
whom Stock Appreciation Rights shall be granted, the number of Shares to be
covered by each Stock Appreciation Right Award, the grant price thereof and the
conditions and limitations applicable to the exercise thereof.  A Stock
Appreciation Right may be granted in tandem with another Award, in addition to
another Award, or freestanding and unrelated to another Award.  A Stock
Appreciation Right granted in tandem with or in addition to another Award may
be granted either at the same time as such other Award or at a later time.

                 (i)      Grant Price.  The grant price of a Stock Appreciation
         Right shall be determined by the Committee on the date of grant.

                 (ii)     Other Terms and Conditions.  Subject to the terms of
         the Plan and any applicable Award Agreement, the Committee shall
         determine, at or after the grant of a Stock Appreciation Right, the
         term, methods of exercise, methods of settlement, and any other terms
         and conditions of any Stock Appreciation Right.  Any such
         determination by the Committee may be changed by the Committee from
         time to time and may govern the exercise of Stock Appreciation Rights
         granted or exercised prior to such determination as well as Stock
         Appreciation Rights granted or exercised thereafter.  The Committee
         may impose such conditions or restrictions on the exercise of any
         Stock Appreciation Right as it shall deem appropriate.

         (c)     Restricted Stock.  Subject to the provisions of the Plan, the
Committee shall have the authority to determine the Participants to whom
Restricted Stock shall be granted, the number of Shares of Restricted Stock to
be granted to each such Participant, the duration of the Restricted Period
during which, and the conditions, including performance criteria, if any, under
which, the Restricted Stock may be forfeited to the Company, and the other
terms and conditions of such Awards.

                 (i)      Dividends.  Dividends paid on Restricted Stock may be
         paid directly to the Participant, may be subject to risk of forfeiture
         and/or transfer restrictions during any period established by the
         Committee or sequestered and held in a bookkeeping cash account (with
         or without interest) or reinvested on an immediate or deferred basis
         in additional shares of Common Stock, which credit or shares may be
         subject to the same restrictions as the underlying Award or such other
         restrictions, all as determined by the Committee in its discretion.

                 (ii)     Registration.  Any Restricted Stock may be evidenced
         in such manner as the Committee shall deem appropriate, including,
         without limitation, book-entry registration or issuance of a stock
         certificate or certificates.  In the event any stock certificate is
         issued in respect of Restricted Stock granted under the Plan, such
         certificate shall be registered in the name of the Participant and
         shall bear an appropriate legend referring to the terms, conditions,
         and restrictions applicable to such Restricted Stock.





                                      -6-
<PAGE>   7
                 (iii)    Forfeiture and Restrictions Lapse.  Except as
         otherwise determined by the Committee or the terms of the Award that
         granted the Restricted Stock, upon termination of a Participant's
         employment (as determined under criteria established by the Committee)
         for any reason during the applicable Restricted Period, all Restricted
         Stock shall be forfeited by the Participant and re-acquired by the
         Company.  The Committee may, when it finds that a waiver would be in
         the best interests of the Company and not cause such Award, if it is
         intended to qualify as performance based compensation under Section
         162(m) of the Code, to fail to so qualify under Section 162(m) of the
         Code, waive in whole or in part any or all remaining restrictions with
         respect to such Participant's Restricted Stock.  Unrestricted Shares,
         evidenced in such manner as the Committee shall deem appropriate,
         shall be issued to the holder of Restricted Stock promptly after the
         applicable restrictions have lapsed or otherwise been satisfied.

                 (iv)     Transfer Restrictions.  During the Restricted Period,
         Restricted Stock will be subject to the limitations on transfer as
         provided in Section 6(j)(iii).

         (d)     Performance Awards.  The Committee shall have the authority to
determine the Participants who shall receive a Performance Award, which shall
be denominated as a cash amount at the time of grant and confer on the
Participant the right to receive payment of such Award, in whole or in part,
upon the achievement of such performance goals during such performance periods
as the Committee shall establish with respect to the Award.

                 (i)      Terms and Conditions.  Subject to the terms of the
         Plan and any applicable Award Agreement, the Committee shall determine
         the performance goals to be achieved during any performance period,
         the length of any performance period, the amount of any Performance
         Award and the amount of any payment or transfer to be made pursuant to
         any Performance Award.

                 (ii)     Payment of Performance Awards.  Performance Awards
         may be paid (in cash and/or in Shares, in the sole discretion of the
         Committee) in a lump sum or in installments following the close of the
         performance period, in accordance with procedures established by the
         Committee with respect to such Award.

         (e)     Bonus Shares.  The Committee shall have the authority, in its
discretion, to grant Bonus Shares to Participants.  Each Bonus Share shall
constitute a transfer of an unrestricted Share to the Participant, without
other payment therefor, as additional compensation for the Participant's
services to the Company.

         (f)     Phantom Shares.  The Committee shall have the authority to
grant Awards of Phantom Shares to Participants upon such terms and conditions
as the Committee may determine.

                 (i)      Terms and Conditions.  Each Phantom Share Award shall
         constitute an agreement by the Company to issue or transfer a
         specified number of Shares or pay an





                                      -7-
<PAGE>   8
         amount of cash equal to a specified number of Shares, or a combination
         thereof to the Participant in the future, subject to the fulfillment
         during the Restricted Period of such conditions, including performance
         objectives, if any, as the Committee may specify at the date of grant.
         During the Restricted Period, the Participant shall not have any right
         to transfer any rights under the subject Award, shall not have any
         rights of ownership in the Phantom Shares and shall not have any right
         to vote such shares.

                 (ii)     Dividends.  Any Phantom Share award may provide that
         any or all dividends or other distributions paid on Shares during the
         Restricted Period be credited in a cash bookkeeping account (without
         interest) or that equivalent additional Phantom Shares be awarded,
         which account or shares may be subject to the same restrictions as the
         underlying Award or such other restrictions as the Committee may
         determine.

         (g)     Cash Awards.  The Committee shall have the authority to
determine the Participants to whom Cash Awards shall be granted, the amount,
and the terms or conditions, if any, as additional compensation for the
Participant's services to the Company or its Affiliates.  A Cash Award may be
granted (simultaneously or subsequently) separately or in tandem with another
Award and may entitle a Participant to receive a specified amount of cash from
the Company upon such other Award becoming taxable to the Participant, which
cash amount may be based on a formula relating to the anticipated taxable
income associated with such other Award and the payment of the Cash Award.

         (h)     Other Stock-Based Awards.  The Committee may also grant to
Participants an Other Stock-Based Award, which shall consist of a right which
is an Award denominated or payable in, valued in whole or in part by reference
to, or otherwise based on or related to, Shares as is deemed by the Committee
to be consistent with the purposes of the Plan.  Subject to the terms of the
Plan, the Committee shall determine the terms and conditions of any such Other
Stock- Based Award.

         (i)     Replacement Grants.       Awards may be granted from time to
time in substitution for similar awards held by employees of other corporations
who become Participants as the result of a merger or consolidation of the
employing corporation with the Company or any subsidiary, or the acquisition by
the Company or any subsidiary of the assets of the employing corporation, or
the acquisition by the Company or any subsidiary or an affiliate of stock of
the employing corporation.  The terms and conditions of substitute Awards
granted may vary from the terms and conditions set forth in the Plan, to the
extent the Committee, at the time of grant, deems it appropriate to conform, in
whole or in part, to the provisions of awards in substitution for which they
are granted.

         (j)     General.

                 (i)      Awards May Be Granted Separately or Together.  Awards
         may, in the discretion of the Committee, be granted either alone or in
         addition to, in tandem with, or in substitution for any other Award
         granted under the Plan or any award granted under any other plan of
         the Company or any Affiliate.  Awards granted in addition to or in
         tandem with other Awards or awards granted under any other plan of the
         Company or any Affiliate may





                                      -8-
<PAGE>   9
         be granted either at the same time as or at a different time from the
         grant of such other Awards or awards.

                 (ii)     Forms of Payment by Company Under Awards.  Subject to
         the terms of the Plan and of any applicable Award Agreement, payments
         or transfers to be made by the Company or an Affiliate upon the grant,
         exercise or payment of an Award may be made in such form or forms as
         the Committee shall determine, including, without limitation, cash,
         Shares, other securities, other Awards or other property, or any
         combination thereof, and may be made in a single payment or transfer,
         in installments, or on a deferred basis, in each case in accordance
         with rules and procedures established by the Committee.  Such rules
         and procedures may include, without limitation, provisions for the
         payment or crediting of reasonable interest on installment or deferred
         payments.

                 (iii)    Limits on Transfer of Awards.

                          (A)     Except as provided in (C) below, each Award,
                 and each right under any Award, shall be exercisable only by
                 the Participant during the Participant's lifetime, or, if
                 permissible under applicable law, by the Participant's
                 guardian or legal representative as determined by the
                 Committee.

                          (B)     Except as provided in (C) below, no Award and
                 no right under any such Award may be assigned, alienated,
                 pledged, attached, sold or otherwise transferred or encumbered
                 by a Participant otherwise than by will or by the laws of
                 descent and distribution (or, in the case of Restricted Stock,
                 to the Company) and any such purported assignment, alienation,
                 pledge, attachment, sale, transfer or encumbrance shall be
                 void and unenforceable against the Company or any Affiliate.

                          (C)     Notwithstanding anything in the Plan to the
                 contrary, to the extent specifically provided by the Committee
                 with respect to a grant, an Award other than an Incentive
                 Stock Option may be transferred to immediate family members or
                 related family trusts, limited partnerships or similar
                 entities or on such terms and conditions as the Committee may
                 establish.

                 (iv)     Term of Awards.  The term of each Award shall be for
         such period as may be determined by the Committee; provided, that in
         no event shall the term of any Award exceed a period of 10 years from
         the date of its grant.

                 (v)      Share Certificates.  All certificates for Shares or
         other securities of the Company or any Affiliate delivered under the
         Plan pursuant to any Award or the exercise thereof shall be subject to
         such stop transfer orders and other restrictions as the Committee may
         deem advisable under the Plan or the rules, regulations, and other
         requirements of the SEC, any stock exchange upon which such Shares or
         other securities are then listed, and any





                                      -9-
<PAGE>   10
         applicable Federal or state laws, and the Committee may cause a legend
         or legends to be put on any such certificates to make appropriate
         reference to such restrictions.

                 (vi)     Consideration for Grants.  Awards may be granted for
         no cash consideration or for such consideration as the Committee
         determines including, without limitation, such minimal cash
         consideration as may be required by applicable law.

                 (vii)    Delivery of Shares or other Securities and Payment by
         Participant of Consideration.  No Shares or other securities shall be
         delivered pursuant to any Award until payment in full of any amount
         required to be paid pursuant to the Plan or the applicable Award
         Agreement (including, without limitation, any exercise price, tax
         payment or tax withholding) is received by the Company.  Such payment
         may be made by such method or methods and in such form or forms as the
         Committee shall determine, including, without limitation, cash,
         Shares, other securities, other Awards or other property, withholding
         of Shares, cashless exercise with simultaneous sale, or any
         combination thereof; provided that the combined value, as determined
         by the Committee, of all cash and cash equivalents and the Fair Market
         Value of any such Shares or other property so tendered to the Company,
         as of the date of such tender, is at least equal to the full amount
         required to be paid pursuant to the Plan or the applicable Award
         Agreement to the Company.

                 (viii)   Performance Criteria and Payment Limits.  The
         Committee shall establish performance goals applicable to those Awards
         (other than Options and Rights) the payment of which is intended by
         the Committee to qualify as "performance-based compensation" as
         described in Section 162(m)(4)(C) of the Code.  Until changed by the
         Committee, the performance goals shall be based upon the attainment of
         such target levels of net income, cash flows, return on equity, profit
         margin or sales, stock price, and/or earnings per share as may be
         specified by the Committee.  Which factor or factors to be used with
         respect to any grant, and the weight to be accorded thereto if more
         than one factor is used, shall be determined by the Committee at the
         time of grant.  With respect to any Restricted Stock Award, Phantom
         Stock Award, or Cash Award granted in tandem with, and expressed as a
         percentage of, a Share-denominated Award, which is intended to qualify
         as "performance-based compensation", the maximum payment to any
         Participant with respect to such Award in any calendar year shall be
         an amount (in cash and/or in Shares) equal to the Fair Market Value of
         the number of Shares subject to such Award.

         SECTION 7.   Amendment and Termination.

         Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:

                 (i)      Amendments to the Plan.  The Board or the Committee
         may amend, alter, suspend, discontinue, or terminate the Plan without
         the consent of any stockholder, Participant, other holder or
         beneficiary of an Award, or other Person; provided, however,





                                      -10-
<PAGE>   11
         notwithstanding any other provision of the Plan or any Award
         Agreement, without the approval of the stockholders of the Company no
         such amendment, alteration, suspension, discontinuation, or
         termination shall be made that would increase the total number of
         Shares available for Awards under the Plan, except as provided in
         Section 4(c) of the Plan.

                 (ii)     Amendments to Awards.  The Committee may waive any
         conditions or rights under, amend any terms of, or alter any Award
         theretofore granted, provided no change, other than pursuant to
         Section 7(c), in any Award shall reduce the benefit to Participant
         without the consent of such Participant.  Notwithstanding the
         foregoing, with respect to any Award intended to qualify as
         performance-based compensation under Section 162(m) of the Code, no
         adjustment shall be authorized to the extent such adjustment would
         cause the Award to fail to so qualify.

                 (iii)    Adjustment of Awards Upon the Occurrence of Certain
         Unusual or Nonrecurring Events.  The Committee is hereby authorized to
         make adjustments in the terms and conditions of, and the criteria
         included in, Awards in recognition of unusual or nonrecurring events
         (including, without limitation, the events described in Section 4(c)
         of the Plan) affecting the Company, any Affiliate, or the financial
         statements of the Company or any Affiliate, or of changes in
         applicable laws, regulations, or accounting principles, whenever the
         Committee determines that such adjustments are appropriate in order to
         prevent dilution or enlargement of the benefits or potential benefits
         intended to be made available under the Plan.  Notwithstanding the
         foregoing, with respect to any Award intended to qualify as
         performance-based compensation under Section 162(m) of the Code, no
         adjustment shall be authorized to the extent such adjustment would
         cause the Award to fail to so qualify.

         SECTION 8.   Change in Control.

         Notwithstanding any other  provision of this Plan to the contrary, in
the event of a Change in Control of the Company all outstanding Awards
automatically shall become fully vested immediately prior to such Change in
Control (or such earlier time as set by the Committee), all restrictions, if
any, with respect to such Awards shall lapse, and all performance criteria, if
any, with respect to such Awards shall be deemed to have been met in full.  For
purposes of this Plan, a "Change in Control" shall be deemed to occur:

                 (i)    any person, entity or group (as such terms are used in
       Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as
       amended (the "Act"), other than the Company or its subsidiaries or an
       employee benefit plan of the Company or its subsidiaries, acquires,
       directly or indirectly, the beneficial ownership (as defined in Section
       13(d) of the Act) of any voting security of the Company and immediately
       after such acquisition such person is, directly or indirectly, the
       beneficial owner of voting securities representing 20% or more of the
       total voting power of all of the then outstanding voting securities of

                 (ii)   upon the first purchase of the Company's common stock
       pursuant to a tender or exchange offer (other than a tender or exchange
       offer made by the Company);

                 (iii)  the stockholders of the Company shall approve a merger,
       consolidation, recapitalization or reorganization of the Company, or a
       reverse stock split of outstanding voting securities, or consummation of
       any such transaction if stockholder approval is not obtained, other than
       any such transaction which would result in at least 75% of the total
       voting power represented by the voting securities of the surviving
       entity outstanding immediately after such transaction being beneficially
       owned by the holders of all of the outstanding voting securities of the
       Company immediately prior to the transactions with the voting power of
       each such continuing holder relative to other such continuing holders
       not substantially altered in the transaction;

                 (iv)   the stockholders of the Company shall approve a plan of
       complete liquidation or dissolution of the Company or an agreement for
       the sale or disposition by the Company of all or substantially all of
       the Company's assets; or

                 (v)    if, at any time during any period of two consecutive
       years, individuals who at the beginning of such period constitute the
       Board cease for any reason to constitute at least a majority thereof,
       unless the election or nomination for the election by the Company's
       stockholders of each new director was approved by a vote of at least
       two-thirds of the directors then still in office who were directors at
       the beginning of the period.

       SECTION 9.   General Provisions.

       (a)    No Rights to Awards.  No Employee, Participant or other Person
shall have any claim to be granted any Award, and there is no obligation for
uniformity of treatment of Employees, Participants, or holders or beneficiaries
of Awards.  The terms and conditions of Awards need not be the same with
respect to each recipient.

       (b)    Withholding.  The Company or any Affiliate is authorized to
withhold from any Award, from any payment due or transfer made under any Award
or under the Plan or from any compensation or other amount owing to a
Participant the amount (in cash, Shares, other securities, Shares that would
otherwise be issued pursuant to such Award, other Awards or other property) of
any applicable taxes payable in respect of an Award, its exercise, the lapse of
restrictions thereon, or any payment or transfer under an Award or under the
Plan and to take such other action as may be necessary in the opinion of the
Company to satisfy all obligations for the payment of such taxes.  In addition,
the Committee may provide, in an Award Agreement, that the Participant may
direct the Company to satisfy such Participant's tax obligation through the
withholding of Shares otherwise to be acquired upon the exercise or payment of
such Award.

       (c)    No Right to Employment.  The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate.  Further, the





                                      -12-
<PAGE>   13
Company or an Affiliate may at any time dismiss a Participant from employment,
free from any liability or any claim under the Plan, unless otherwise expressly
provided in the Plan or in any Award Agreement.

       (d)    Governing Law.  The validity, construction, and effect of the
Plan and any rules and regulations relating to the Plan shall be determined in
accordance with the laws of the State of Delaware and applicable Federal law.

       (e)    Severability.  If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to the applicable laws, or if it cannot
be construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall
be stricken as to such jurisdiction, Person or Award and the remainder of the
Plan and any such Award shall remain in full force and effect.

       (f)    Other Laws.  The Committee may refuse to issue or transfer any
Shares or other consideration under an Award if, acting in its sole discretion,
it determines that the issuance of transfer or such Shares or such other
consideration might violate any applicable law or regulation or entitle the
Company to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant, other holder or beneficiary
in connection with the exercise of such Award shall be promptly refunded to the
relevant Participant, holder or beneficiary.

       (g)    No Trust or Fund Created.  Neither the Plan nor the Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant
or any other Person.  To the extent that any Person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any general unsecured creditor of the
Company or any Affiliate.

       (h)    No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any
rights thereto shall be canceled, terminated, or otherwise eliminated.

       (i)    Headings.  Headings are given to the Sections and subsections of
the Plan solely as a convenience to facilitate reference.  Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

       (j)    Parachute Tax Gross-Up.  To the extent that the grant, payment,
or acceleration of vesting or payment, whether in cash or stock, of any Award
made to a Participant under the Plan (a "Benefit") is subject to a golden
parachute excise tax under Section 4999(a) of the Code (a 





                                      -13-
<PAGE>   14
"Parachute Tax"), the Company shall pay such person an amount of cash (the
"Gross-up Amount") such that the "net" Benefit received by the person under this
Plan, after paying all applicable Parachute Taxes (including those on the
Gross-up Amount) and any federal or state taxes on the Gross-up Amount, shall be
equal to the Benefit that such person would have received if such Parachute Tax
had not been applicable.

       SECTION 10.   Effective Date of the Plan.

       The Plan shall be effective as of the date of its approval by the Board.

       SECTION 11.   Term of the Plan.

       No Award shall be granted under the Plan after the 10th anniversary of
the approved date. However, unless otherwise expressly provided in the Plan or
in an applicable Award Agreement, any Award granted prior to such termination,
and the authority of the Board or the Committee to amend, alter, adjust,
suspend, discontinue, or terminate any such Award or to waive any conditions or
rights under such Award, shall extend beyond such termination date.

Committee who are present at any meeting thereof at which a quorum is present,
or acts unanimously approved by the members of the Committee in writing, shall
be the acts of the Committee. Subject to the terms of the Plan and applicable
law, and in addition to other express powers and authorizations conferred on

to: (i) determine the members of the Board who are Directors; (ii) interpret

                                      -2-
<PAGE>   3
Shares covered by such Option, to the extent of any such forfeiture,

Options may be granted.

         (b)     Sources of Shares Deliverable Under Options.  Any Shares
delivered pursuant to an Option may consist, in whole or in part, of authorized
and unissued Shares or of treasury Shares.

         (c)     Adjustments.  In the event that the Committee determines that
any dividend or other distribution (whether in the form of cash, Shares, other

split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Shares or other securities of the Company, issuance
of warrants or other rights to purchase Shares or other securities of the
Company, or other similar corporate transaction or event affects the Shares
such that an adjustment is determined by the Committee to be appropriate in
order to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, then the Committee shall, in such
manner as it may deem equitable, adjust any or all of (i) the number and type
of Shares (or other securities or property) with respect to which Options may
be granted, (ii) the number and type of Shares (or other securities or
property) subject to outstanding Options, and (iii) the grant or exercise price

         SECTION 5.   Eligibility.

        Each member of the Board who is a Director automatically shall be a
Participant.

         SECTION 6.   Options.

         (a)     Initial Grants. Each Director who serves in such capacity on
the date of the closing of the initial public offering of the Common Stock (the
"IPO") shall automatically receive, on such date, an Option for 5,000 shares of
Common Stock.  Each person who is elected as a Director for the first time
after such IPO date shall automatically receive, on the date of his or her
election, an Option for 5,000 shares of Common Stock.

         (b)     Annual Grants.  On each September 30th that this Plan is in
effect, each Director on that day shall automatically receive an Option for
5,000 shares of Common Stock.

         (c)     Exercise Price.  Subject to adjustment pursuant to Section
4(c), the purchase price per Share purchasable under an Option shall be the
Fair Market Value per Share at the time the Option is granted.

         (d)     Vesting.  Subject to the further provisions of the Plan, each
Option shall become vested (exercisable) as to 20% of the shares of Common
Stock granted on each anniversary of the date of grant of such Option.





                                      -3-
<PAGE>   4
         (e)     Time and Method of Exercise.  An Option may be exercised in
whole or in part by cash, check acceptable to the Company, Shares already owned
for more than six months, a "cashless-broker" exercise (through procedures
approved by the Company), or any combination thereof, having a Fair Market
Value on the exercise date equal to the relevant exercise price.

         (f)     Term.  Each Option shall expire 10 years from its date of
grant, but shall be subject to earlier termination as follows: Options, to the
extent exercisable as of the date the Participant ceases to serve as a member
of the Board, must be exercised within three months of such date unless such
termination results from the Participant's death or disability, in which case
the Participant's Options may be exercised by the Participant's legal
representative or the person to whom the Participant's rights shall pass by
will or the laws of descent and distribution, as the case may be, within one
year from the date of termination; provided, however, that such event shall not
extend the normal expiration date of such Options.

         (g)     Automatic Limits.  In the event that the number of shares of
Common Stock available for grants under this Plan is insufficient to make all
automatic grants provided for in paragraphs (a) or (b) above on the applicable
date, then all Directors who are entitled to a grant on such date shall share
ratably in the number of shares then available for grant under this Plan, and
shall have no right to receive a grant with respect to the deficiencies in the
number of available shares and all future grants under this Section 6 shall
terminate.

         (h)     Discretionary Grants.  The Board may make additional grants of
Options to a Director when, in the discretion of the Board, such additional
grant is merited by the circumstances.  Such discretionary grants shall be on
such terms as the Board may establish for the grant.

         (i)     Limits on Transfer of Options.

                 (A)      Except as provided in (C) below, each Option, and
         each right under any Option, shall be exercisable only by the
         Participant during the Participant's lifetime, or, if permissible
         under applicable law, by the Participant's guardian or legal
         representative as determined by the Committee.

                 (B)      Except as provided in (C) below, no Option and no
         right under any such Option may be assigned, alienated, pledged,
         attached, sold or otherwise transferred or encumbered by a Participant
         otherwise than by will or by the laws of descent and distribution and
         any such purported assignment, alienation, pledge, attachment, sale,
         transfer or encumbrance shall be void and unenforceable against the
         Company.

                 (C)      Notwithstanding anything in the Plan to the contrary,
         an Option may be transferred to immediate family members or related
         family trusts, limited partnerships or similar entities or on such
         terms and conditions as the Committee may establish.





                                      -4-
<PAGE>   5
         (j)     Share Certificates.  All certificates for Shares or other
securities of the Company or any affiliate delivered under the Plan pursuant to
any Option or the exercise thereof shall be subject to such stop transfer
orders and other restrictions as the Committee may deem advisable under the
Plan or the rules, regulations, and other requirements of the SEC, any stock
exchange upon which such Shares or other securities are then listed, and any
applicable Federal or state laws, and the Committee may cause a legend or
legends to be put on any such certificates to make appropriate reference to
such restrictions.

         (k)     Delivery of Shares or other Securities and Payment by
Participant of Consideration.  No Shares or other securities shall be delivered
pursuant to any Option until payment in full of any amount required to be paid
pursuant to the Plan or the applicable Option agreement (including, without
limitation, any exercise price, tax payment or tax withholding) is received by
the Company.

         SECTION 7.   Amendment and Termination.

         Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Option Agreement or in the Plan:

                 (i)      Amendments to the Plan.  The Board or the Committee
         may amend, alter, suspend, discontinue, or terminate the Plan without
         the consent of any stockholder, Participant, other holder or
         beneficiary of an Option, or other Person; provided, however,
         notwithstanding any other provision of the Plan or any Option
         Agreement, without the approval of the stockholders of the Company no
         such amendment, alteration, suspension, discontinuation, or
         termination shall be made that would increase the total number of
         Shares available for Options under the Plan, except as provided in
         Section 4(c) of the Plan.

                 (ii)     Adjustment of Options Upon the Occurrence of Certain
         Unusual or Nonrecurring Events.  The Committee is hereby authorized to
         make adjustments in the terms and conditions of, and the criteria
         included in, Options in recognition of unusual or nonrecurring events
         (including, without limitation, the events described in Section 4(c)
         of the Plan) affecting the Company, any Affiliate, or the financial
         statements of the Company or any Affiliate, or of changes in
         applicable laws, regulations, or accounting principles, whenever the
         Committee determines that such adjustments are appropriate in order to
         prevent dilution or enlargement of the benefits or potential benefits
         intended to be made available under the Plan.

         SECTION 8.   Change in Control.

         Notwithstanding any other  provision of this Plan to the contrary, in
the event of a Change in Control of the Company all outstanding Options
automatically shall become fully vested immediately prior to such Change in
Control (or such earlier time as set by the Committee).  For purposes of this
Plan, a "Change in Control" shall be deemed to occur:

<PAGE>   6
              (i)    any person, entity or group (as such terms are used in
       Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as
       amended (the "Act"), other than the Company or its subsidiaries or an
       employee benefit plan of the Company or its subsidiaries, acquires,
       directly or indirectly, the beneficial ownership (as defined in Section
       13(d) of the Act) of any voting security of the Company and immediately
       after such acquisition such person is, directly or indirectly, the
       beneficial owner of voting securities representing 20% or more of the
       total voting power of all of the then outstanding voting securities of
       the Company entitled to vote generally in the election of directors;

              (ii)   upon the first purchase of the Company's common stock
       pursuant to a tender or exchange offer (other than a tender or exchange
       offer made by the Company);

              (iii)  the stockholders of the Company shall approve a merger,
       consolidation, recapitalization or reorganization of the Company, or a
       reverse stock split of outstanding voting securities, or consummation of
       any such transaction if stockholder approval is not obtained, other than
       any such transaction which would result in at least 75% of the total
       voting power represented by the voting securities of the surviving
       entity outstanding immediately after such transaction being beneficially
       owned by the holders of all of the outstanding voting securities of the
       Company immediately prior to the transactions with the voting power of
       each such continuing holder relative to other such continuing holders
       not substantially altered in the transaction;

              (iv)   the stockholders of  the Company shall approve a plan of
       complete liquidation or dissolution of the Company or an agreement for
       the sale or disposition by the Company of all or substantially all of
       the Company's assets; or

              (v)    if, at any time during any period of two consecutive
       years, individuals who at the beginning of such period constitute the
       Board cease for any reason to constitute at least a majority thereof,
       unless the election or nomination for the election by the Company's
       stockholders of each new director was approved by a vote of at least
       two-thirds of the directors then still in office who were directors at
       the beginning of the period.

       SECTION 9.   General Provisions.

       (a)    No Rights to Options.  No Participant or other Person shall have
any claim to be granted any Option, and there is no obligation for uniformity
of treatment of Participants or holders or beneficiaries of Options.

       (b)    Withholding.  The Company is authorized to withhold from any
Option or from any compensation or other amount owing to a Participant the
amount (in cash, Shares, other securities, Shares that would otherwise be
issued pursuant to such Option, other Options or other property) of any
applicable taxes payable in respect of an Option, its exercise, or any payment
or transfer under an Option or under the Plan and to take such other action as
may be necessary in the opinion of the





                                      -6-
<PAGE>   7
Company to satisfy all obligations for the payment of such taxes.  In addition,
the Participant may direct the Company to satisfy such Participant's tax
obligation through the withholding of Shares otherwise to be acquired upon the
exercise or payment of such Option.

       (c)    No Right to Continued Board Membership.  The grant of an Option
shall not be construed as giving a Participant the right to be a member of the
Board.

       (d)    Governing Law.  The validity, construction, and effect of the
Plan and any rules and regulations relating to the Plan shall be determined in
accordance with the laws of the State of Delaware and applicable Federal law.

       (e)    Severability.  If any provision of the Plan or any Option is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Option, or would disqualify the Plan or any
Option under any law deemed applicable by the Committee, such provision shall
be construed or deemed amended to conform to the applicable laws, or if it
cannot be construed or deemed amended without , in the determination of the
Committee, materially altering the intent of the Plan or the Option, such
provision shall be stricken as to such jurisdiction, Person or Option and the
remainder of the Plan and any such Option shall remain in full force and
effect.

       (f)    Other Laws.  The Committee may refuse to issue or transfer any
Shares or other consideration under an Option if, acting in its sole
discretion, it determines that the issuance of transfer or such Shares or such
other consideration might violate any applicable law or regulation or entitle
the Company to recover the same under Section 16(b) of the Exchange Act, and
any payment tendered to the Company by a Participant, other holder or
beneficiary in connection with the exercise of such Option shall be promptly
refunded to the relevant Participant, holder or beneficiary.

       (g)    No Trust or Fund Created.  Neither the Plan nor the Option shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company and a Participant or any other
Person.  To the extent that any Person acquires a right to receive payments
from the Company pursuant to an Option, such right shall be no greater than the
right of any general unsecured creditor of the Company.

       (h)    No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Option, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares or whether such fractional Shares or any
rights thereto shall be canceled, terminated, or otherwise eliminated.

       (i)    Headings.  Headings are given to the Sections and subsections of
the Plan solely as a convenience to facilitate reference.  Such headings shall

       (j)    Parachute Tax Gross-Up.  To the extent that the grant, payment,
or acceleration of vesting or payment, whether in cash or stock, of any Option
made to a Participant under the Plan (a "Benefit") is subject to a golden
parachute excise tax under Section 4999(a) of the Internal Revenue Code (a
"Parachute Tax"), the Company shall pay such person an amount of cash (the
"Gross-up Amount") such that the "net" Benefit received by the person under
this Plan, after paying all applicable Parachute Taxes (including those on the
Gross-up Amount) and any federal or state taxes on the Gross-up Amount, shall
be equal to the Benefit that such person would have received if such Parachute
Tax had not been applicable.

       The Plan shall be effective as of the date of its approval by the Board.

       SECTION 11.   Term of the Plan.

the approved date. However, unless otherwise expressly provided in the Plan,
any Option granted prior to such termination, and the authority of the Board or
the Committee to amend, alter, adjust, or terminate such Option shall extend
beyond such termination date.
