  The following summary is qualified in its entirety by reference to, and
should be read in conjunction with, the more detailed information and financial
statements, including the notes thereto, appearing elsewhere in this
Prospectus. See "Risk Factors" for information that should be carefully
considered by prospective investors.

                                  THE COMPANY

Integrated Electrical Services, Inc. ("IES" or the "Company"), a Delaware
Corporation, was founded in June 1997 to create a leading national provider and
consolidator of electrical contracting and maintenance services, focusing
primarily on the commercial, industrial and residential markets.  On January 30,
1998, concurrent with the closing of its initial public offering ("IPO" or
"Offering") of common stock, IES acquired, in separate transactions 16 companies
and related entities engaged in all facets of electrical contracting and
maintenance services (collectively, the "Founding Companies" or the "Founding
Company Acquisitions").  Subsequent to its IPO, and through September 11, 1998,
the Company has acquired 19 additional electrical contracting and maintenance
businesses (the "Post IPO Acquisitions").  Of these 19 Post IPO Acquisitions, 18
were accounted for using the purchase method of accounting (the "Post IPO
Purchased Companies") and one was accounted for using the pooling-of-interests
method of accounting (the "Pooled Company").  IES has acquired 35 electrical
contracting and maintenance service companies (collectively the "Companies")
with pro forma combined revenues of $705.0 million and $553.3 million for the
year ended September 30, 1997, and the nine months ended June 30, 1998,
respectively, making the Company one of the largest providers of electrical
contracting and maintenance services in the United States. Of such 1997 pro
forma revenues, approximately 80% was derived from commercial (approximately
46%) and industrial (approximately 34%) contracting, approximately 14% was
derived from residential contracting and approximately 6% was derived from
electrical maintenance work. Combined revenues of the  Companies, which have
been in business an average of 21 years, increased at an average compound annual
growth rate of approximately 17% from fiscal 1995 through 1997.

   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  Companies specialize in either commercial and industrial or
residential work, although a few of the  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  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 electrical contracting and maintenance services to the full
range of commercial and industrial customers.

  From fiscal 1995 through 1997, the Companies' revenues from electrical
contracting for commercial and industrial customers have grown at an average
compound annual rate of approximately 17% 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
multi-family home starts, which are in turn affected by interest rates, tax
considerations and





                                       3
<PAGE>   6
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  Companies residential electrical
contracting revenues have grown at an average compound annual rate of
approximately 19% from fiscal 1995 through 1997.

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 has 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 provides increased efficiency in materials purchasing, computer system
development, employee benefits, bonding, insurance and financing. The Company
believes that the diversity of its operations diminishes the effects of
regional and market downturns, offers opportunities to pursue growth in its
existing markets and creates a base of expertise to expand into new markets and
serve new customers.

  The Company leverages 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 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 Companies are members of the IEC and other trade
organizations, and the Company has implemented programs to share best practices
among the Companies and 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 Companies. The Company identifies and shares 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 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





                                       4
<PAGE>   7
   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  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 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  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.

     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 Companies. The Company also is structured to allow it to capitalize
   on the considerable local and regional market knowledge and customer
   relationships possessed by each  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 of the Companies  provides
   competitive advantages in this regard. The Company attracts and develops
   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 have been
   centralized. In addition, by combining overlapping operations of certain of
   the Companies, the Company expects to realize savings in overhead and other
   expenses. The Company uses 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
   additional 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 Companies. At some locations,
   the larger combined workforce provides additional staffing flexibility.





                                       5
<PAGE>   8
  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 
focuses 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 maintenance service businesses that lack the capital
necessary to expand operations will become acquisition candidates. For these
acquisition candidates, the Company provides (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 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 pursues 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
   seeks 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  maintains
   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 acquired the Founding Companies simultaneously with the consummation of
the Offering. Pursuant to the Securities and Exchange Commission's ("SEC") Staff
Accounting Bulletin No. 97 ("SAB97"), Houston-Stafford Electric, Inc. and
subsidiaries ("HSE") is considered for accounting purposes  the entity which
acquired the other Founding Companies and IES (the "Accounting Acquirer").  As
such, IES's consolidated historical financial statements represent the financial
position and results of operations of (i) HSE (as restated to include the
financial position and results of operations of the Pooled Company), and (ii)
the other Founding Companies and the Post IPO Purchased Companies beginning
on their respective dates of acquisition.  The following summary unaudited pro
forma combined financial data present certain data for IES, as adjusted for (i)
the effects of the acquisitions of the Founding Companies and the Post IPO
Purchased Companies, (ii) the effects of certain other pro forma adjustments to
the historical financial statements and (iii) the consummation of the Offering
(including the underwriters exercise of the overallotment option) and the
application of the net proceeds therefrom. Such pro forma  data include the
results of operations of IES  and the other Founding Companies and the Post IPO
Purchased Companies as if their acquisitions, the Offering 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 Companies were not under common control
or management and, therefore, the data presented may not be comparable to or
indicative of future performance.  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 of IES and for certain of the
Acquired Companies and the notes thereto, all included elsewhere in this
Prospectus.

(a) The unaudited pro forma combined income statement data reflect certain
    reductions in salary, bonus and benefits of the owners of the Companies to
    which they have agreed prospectively, and the effect of revisions of certain
    lease agreements between the Companies and certain stockholders of the
    Companies. Additionally, excludes the $13.6 million non-recurring, non-cash
    compensation charge recognized by IES related to the issuance of Common
    Stock to management and the $17.0 million non-recurring, non-cash
    compensation charge recorded by HSE in connection with a note receivable and
    rights held by an officer of HSE which was exchanged for cash and shares of
    IES common stock in connection with the Founding Company Acquisitions. See
    "Certain Transactions."

(b) Reflects amortization of the goodwill recorded as a result of the
    acquisitions of the Founding Companies and the Post IPO Purchased Companies
    over a 40-year period and computed on the basis described in the notes to
    the Unaudited Pro Forma Combined Financial Statements.

(c) Reflects additional interest expense related to the debt discussed in (g)
    below, net of the reduction of interest expense attributable to $8.1
    million of historical debt which was repaid with proceeds from the Offering
    or distributed prior to the acquisitions of the Founding Companies.
    Additionally, reflects elimination of interest income, and a $316,000
    reduction in minority interest expense.

(d) Assumes all pretax income before non-deductible goodwill and other
    permanent items is subject to a 38% overall tax rate.

(e) Includes (i) 12,313,025 shares issued to the owners of the Founding
    Companies, (ii) 1,396,602 shares issued to the management of IES, (iii)
    2,655,709 shares of Restricted Common Stock issued to the founder and
    Chairman of the Board of IES and trusts for the benefit of his children,
    (iv) the 8,050,000 shares sold in the Offering (including the underwriters
    exercise of the overallotment option for 1,050,000 shares), and (v)
    6,341,539 shares issued to the owners of the Post IPO Acquisitions. Also,
    the nine months ended June 30, 1998 includes 357,249 shares computed under
    the treasury stock method related to 3,110,550 options outstanding at
    September 11, 1998. See "Description of Capital Stock."

(f) Reflects the acquisitions of the eight post IPO Acquisitions which closed
    subsequent to June 30, 1998, as if they had occurred on June 30, 1998 as
    described in the notes to the Unaudited Pro Forma Combined Financial
    Statements. The unaudited pro forma combined balance sheet data are based
    upon preliminary estimates, available information and certain assumptions
    that management deems appropriate and should be read in conjunction with the
    other financial information and historical financial statements, and notes
    thereto, included elsewhere in this Prospectus.

(g) Reflects $4.2 million of previously undistributed earnings and nonoperating
    assets, net of liabilities distributed in connection with the acquisitions
    to the owners of the eight post IPO Acquisitions which closed subsequent to
    June 30, 1998. This amount was funded through transfers of cash and
    nonoperating assets. See "Certain Transactions." Also, includes
    approximately $63.6 million of debt incurred net of cash acquired to fund
    the cash portion of the consideration paid for the eight post IPO
    Acquisitions which closed subsequent to June 30, 1998.

                                  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

  Prior to January 30, 1998, the Founding Companies and prior to the date of
acquisition the Post IPO Acquisitions operated 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  Companies cover
periods during which the 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 Companies and other future acquisitions
into one organization in a profitable manner. The inability of the Company to
successfully integrate the 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





                                       9
<PAGE>   12
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 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 maintenance 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."





                                       10
<PAGE>   13
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 a bank line of credit for $175 million for working capital,
capital expenditures, other corporate purposes and acquisitions. The line of
credit is subject to customary drawing conditions. See "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

  The Company's executive officers, directors and affiliates beneficially own
approximately 31% 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."

POSSIBLE VOLATILITY OF STOCK

  The Common Stock is traded on the NYSE, but no assurance can be given that an
active trading market for the Common Stock will continue. The market price of
the Common Stock 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.





                                       11
<PAGE>   14
DEPENDENCE ON KEY PERSONNEL

  The Company's operations are dependent on the continued efforts of its
executive officers and senior management of the Companies. Furthermore, the
Company will be dependent on the senior management of companies that may be
acquired in the future. Although the Company entered 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 September 11, 1998, 28,182,698 shares of Common Stock and 2,655,709
shares of Restricted Common Stock were issued and outstanding. Prior to and
simultaneously with the closing of the Offering, the Company issued 13,709,627
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 addition,  the owners of the Companies have agreed with
the Company not to sell, contract to sell or otherwise dispose of 21,231,920
shares of Common Stock  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. Certain stockholders of the Company have certain piggy-back
registration rights with respect to 16,365,336 shares of Common Stock, which may
be exercised during the two-year period referred to above.  The Company has
outstanding options to purchase up to a total of  approximately 3,110,550 shares
of Common Stock issued pursuant to the Company's Option Stock Plans.

  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.





                                       12
<PAGE>   15
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 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.

                                  THE COMPANY

IES was founded in June 1997 to create a leading national provider and
consolidator of electrical contracting and maintenance services, focusing
primarily on the commercial, industrial and residential markets. Since the
closing of the Offering, IES has acquired 35 companies. The Companies, which
have been in business for an average of 21 years, had pro forma combined year
ended September 30, 1997, and the nine months ended June 30, 1998, revenues of
approximately $705.0 million and $553.0 million, respectively.

  Integrated Electrical Services, Inc. was incorporated in Delaware in June
1997. Its executive offices are located at 515 Post Oak Boulevard, Suite 450,
Houston, Texas 77027, and its telephone number is (713) 860-1500.

                                USE OF PROCEEDS

  This Prospectus relates to shares of Common Stock that may be offered and
issued by the Company from time to time in connection with the acquisitions of
the securities and assets of other businesses. Other than the securities and
assets acquired, there will be no proceeds to the Company from these offerings.

                          PRICE RANGE OF COMMON STOCK

  The Company's Common Stock has traded on the NYSE since January 27, 1998, the

                                DIVIDEND POLICY

  The Company intends to retain all of its earnings, if any, to finance the
expansion of its business and for general corporate purposes, including future
acquisitions, and does not anticipate paying any cash dividends on its Common
Stock for the foreseeable future. In addition, the Company's revolving credit
facility includes, and any additional lines of credit established in the future
may include, restrictions on the ability of the Company to pay dividends
without the consent of the lender.

                            SELECTED FINANCIAL DATA
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

  IES acquired the Founding Companies simultaneously with the consummation of
the Offering on January 30, 1998.  Pursuant to the Securities and Exchange
Commission's ("SEC") Staff Accounting Bulletin No. 97 ("SAB97"), Houston-
Stafford Electric, Inc. and subsidiaries ("HSE") is considered for accounting
purposes  the entity which acquired the other Founding Companies and IES (the
"Accounting Acquirer").  As such, IES's consolidated historical financial
statements represent the financial position and results of operations of (i) HSE
as restated to include the financial position and results of operations of the
Pooled Company, and (ii) the other Founding Companies and the Post IPO
Purchased Companies beginning on their respective dates of acquisition.  The
following selected historical financial data for IES 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 the
consolidated audited financial statements of IES 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 as of June 30, 1998, and for the nine months ended
June 30, 1997 and 1998, nine months ended September 30, 1997 and as of December
31, 1993 and for the year ended December 31, 1993, have been derived from the
unaudited consolidated financial statements of IES, 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 interim periods presented should not be regarded as
indicative of the results that may be expected for a full year.

  The summary unaudited pro forma combined financial data below present certain
data including IES  as adjusted for (i) the effects of the acquisitions of the
Founding Companies and the Post IPO Purchased Companies, (ii) the effects of
certain other pro forma adjustments to the historical financial statements and
(iii) the consummation of the Offering and the application of the net proceeds
therefrom. Such pro forma data include the results of operations of IES  and the
other Founding Companies and the Post IPO Purchased Companies as if their
acquisitions, the Offering 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 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.

(a) The unaudited pro forma combined income statement data reflect certain
    reductions in salary, bonus and benefits of the owners of the Companies to
    which they have agreed prospectively, and the effect of revisions of
    certain lease agreements between the Companies and certain stockholders of
    the Companies. Additionally, excludes the $13.6 million non-recurring,

    Acquisitions. See "Certain Transactions."

(b) Reflects amortization of the goodwill to be recorded as a result of the
    acquisitions of the Founding Companies and the Post IPO Purchased Companies
    over a 40-year period and computed on the basis described in the notes to
    the Unaudited Pro Forma Combined Financial Statements.

(c) Reflects additional interest expense related to the debt discussed in (g)
    below, net of the reduction of interest expense attributable to $8.1
    million of historical debt which was repaid with proceeds from the Offering
    or distributed prior to the acquisitions of the Founding Companies.
    Additionally, reflects elimination of interest income, and a $316,000
    reduction in minority interest expense.

    exercise of the overallotment option for 1,050,000 shares), and (v)

    September 11, 1998. See "Description of Capital Stock."

(f) Reflects the acquisitions of the 8 post IPO Acquisitions which closed
    subsequent to June 30, 1998, as if they had occurred on June 30, 1998 as
    described in the notes to the Unaudited Pro Forma Combined Financial
    Statements. The unaudited pro forma combined balance sheet data are based
    upon preliminary estimates, available information and certain assumptions
    that management deems appropriate and should be read in conjunction with the
    other financial information and historical financial statements, and notes
    thereto, included elsewhere in this Prospectus.

(g) Reflects $4.2 million of previously undistributed earnings and nonoperating
    assets, net of liabilities distributed in connection with the acquisitions
    to the owners of the 8 post IPO Acquisitions which closed subsequent to June
    30, 1998. This amount was funded through transfers of cash and nonoperating
    assets. See "Certain Transactions." Also, includes approximately $63.6
    million of debt incurred net of cash acquired to fund the cash portion of
    the consideration paid for the 8 post IPO Acquisitions which closed
    subsequent to June 30, 1998,

    financial position of the accounting acquirer (HSE) as of periods ended
    prior to January 30, 1998 (as restated for the Pooled Company) and HSE and
    the Post IPO Purchased Companies beginning on their respective dates of
    acquisition.

    based on (a) the shares issued to acquire HSE and the Pooled Company
    totaling 4,492,039 (basic and diluted) for periods ended prior to January
    30, 1998, and (b) the shares in (a) plus the shares issued to acquire the
    other Founding Companies and the Post IPO Purchased Companies beginning on
    their respective dates of acquisition, along with the incremental shares for
    options outstanding determined using the treasury stock method as follows:

               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. Of the Company's pro forma combined year ended September 30, 1997
revenues of $705.0 million, approximately 80% was derived from commercial and
industrial contracting, approximately 14% was derived from residential
contracting and approximately 6% was derived from electrical maintenance work.
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
greater 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 Companies have agreed to reductions in their compensation and
related benefits 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 has realized 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 Companies; (iv)
consolidation of operations in certain locations and (v) greater volume
discounts from suppliers of materials, parts and supplies. Offsetting these
savings are costs related to the Company's corporate management, costs of being
a public company and costs of integrating companies acquired in acquisitions.

  As a result of the acquisitions of the Companies accounted for as purchases,
the excess of the consideration paid over the fair value of the net assets
acquired was recorded as goodwill on the Company's balance sheet and is being
amortized as a non-cash charge to the income statement over a 40-year period.

  Integrated Electrical Services, Inc. and Subsidiaries Consolidated results for
the nine months ended June 30, 1998 compared to the nine months ended June 30,
1997

  Revenues increased $139.8 million, or 175%, from $79.8 million for the nine 
months ended June 30, 1997, to $219.6 million for the nine months ended June 30,
1998. The increase in revenues is principally due to the acquisition of  the
Founding Companies (excluding Houston-Stafford) on January 30, 1998, and the
acquisition of the Post IPO Acquisitions during the three months ended June 30,
1998.

  Gross profit increased $31.5 million, or 215%, from $14.7 million for the nine
months ended June 30, 1997, to $46.2 million for the nine months ended June 30,
1998. The increase in gross profit was principally due to the Acquisitions of
the Founding Companies (excluding Houston-Stafford) on January 30, 1998, and the
acquisitions of the Post IPO Acquisitions during the three months ended June 30,
1998.  As a percentage of revenues, gross profit increased from 18.4% in 1997 to
21.0% in 1998.  This increase is attributed to Houston Stafford's lower markup
on certain materials acquired under significant customer contracts and
additional overtime in the prior year.

  Selling, general and administrative expenses increased $19.3 million, or 189%,
from $10.2 million for the nine months ended June 30, 1997, to $29.5 million for
the nine months ended June 30, 1998. This increase in selling, general and
administrative expenses was primarily attributable to the Acquisitions of the
Founding Companies (excluding Houston-Stafford) on January 30, 1998, the
acquisitions of the Post IPO Acquisitions during the three months ended June 30,
1998, a $5.6 million bonus paid to the owners of Houston-Stafford during the
four months ended in January 1998, compared to a $1.5 million bonus during the
four months ended in January 1997, and approximately $1.7 million of additional
corporate costs incurred in 1998 associated with being a public company which
did not exist in 1997.  Excluding such bonuses and higher corporate costs,
selling, general and administrative expenses as a percentage of revenues
decreased from 10.7% in 1997 to 10.0% in 1998.

  Operating income decreased $6.5 million, or 233%, from $4.5 million for the 
nine months ended June 30, 1997, to $(2.0) million for the nine months ended
June 30, 1998.  This decrease in operating income is primarily attributed to the
Founding Company Acquisitions (excluding Houston-Stafford) on January 30, 1998,
the acquisitions of the Post IPO Acquisitions during the three months ended June
30, 1998, the non-recurring owner bonuses in 1997, which was partially offset by
higher corporate costs discussed above.  As a percentage of revenues, operating
income (excluding the owner bonuses and higher corporate costs noted above)
increased from 7.7% in 1997 to 10.3% in 1998.

  Integrated Electrical Services, Inc. and Subsidiaries Consolidated results for
the year ended September 30, 1997 compared to the year ended December 31, 1996.

  Revenues increased $15.7 million, or 15%, from $101.4 million for the year
ended December 31, 1996 to $117.1 million for the year 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 $4.8 million, or 30%, during the year ended September
30, 1997 to $21.2 million, and gross margin increased to 18% during the year
ended September 30, 1997 from 16% during the year ended December 31, 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 40% from $10.2 million
to $14.3 million. The increase was primarily attributable to an increase in
bonuses for certain key employees and to a lesser degree higher insurance
costs.

  Integrated Electrical Services, Inc. and Subsidiaries Consolidated results for
the year ended December 31, 1996 compared to the year ended December 31, 1995



                                       21
<PAGE>   24

  Revenues increased $28.1 million, or 38%, from $73.3 million for the year
ended December 31, 1995, to $101.4 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 $6.8 million, or 71%, from $9.6 million for the year
ended December 31, 1995 to $16.4 million for the year ended December 31, 1996.
Gross margin increased from 14% to 18% over these periods. The increase in
gross profit amounts and percentages is primarily attributable 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 29% from $7.9 million
to $10.2 million. The increase was attributable to the addition of
administrative infrastructure necessary to support Houston-Stafford'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.

INTEGRATED ELECTRICAL SERVICES, INC. AND SUBSIDIARIES CONSOLIDATED LIQUIDITY
AND CAPITAL RESOURCES

As of June 30, 1998, the Company had cash of $13.3 million and, had borrowed
$20.0 million under its Credit Facility, had $1.0 million of letters of credit
outstanding and had available capacity under its Credit Facility of $49.0
million.

During the nine months ended June 30, 1998, the Company generated $7.9 million
of net cash from operating activities.  Net cash used in investing activities
was $68.2 million, including $66.6 million used for the purchase of businesses.
Net cash flows provided by financing activities was $69.5 million resulting
primarily from $91.5 million of net proceeds from the IPO, $20.6 million from
borrowings under the Company's Credit Facility, reduced by payments of debt
assumed in connection with acquisitions and distributions to the Accounting
Acquirer totaling $42.7 million.

On August 7, 1998, the Company increased its three-year revolving credit
facility to $175.0 million (the "Credit Facility").  The Credit Facility is used
for working capital, capital expenditures, other corporate purposes and
acquisitions.  The amounts borrowed under the Credit Facility bear interest at
an annual rate equal to either (a) the London interbank offered rate ("LIBOR")
plus 1.0% to 2.0%, as determined by the ratio of the Company's total funded debt
to EBITDA (as defined), or (b) the higher of (i) the bank's prime rate and (ii)
the Federal Funds rate plus 0.5%, plus up to an additional 0.5% as determined by
the ratio of the Company's total funded debt to EBITDA.  Commitment fees of
0.25% to 0.375%, as determined by the ratio of the Company's total funded debt
to EBITDA, are due on any unused borrowing capacity under the Credit Facility.
The Company's subsidiaries have guaranteed the repayment of all amounts due
under the facility, and the facility is secured by the capital stock of the
guarantors and the accounts receivable of the Company and the guarantors.  The
Credit Facility requires the consent of the lenders for acquisitions exceeding a
certain level of cash consideration, prohibits the payment of cash dividends on
the Company's common stock, restricts the ability of the Company to incur other
indebtedness and requires the Company to comply with certain financial
covenants.  Availability of the Credit Facility is subject to customary drawing
conditions.

The Company anticipates that its cash flow from operations and proceeds from
its Credit Facility 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.

Through September 14, 1998, the Company utilized a combination of existing
cash, borrowings under its credit facility, and its common stock to acquire 35
companies with total 1997 revenues of approximately $ 705.0 million.  The cash
component of the consideration paid for these companies was funded with
proceeds from the IPO, existing cash, and borrowings under the Credit Facility.
As of September 14, 1998, $91.0 million was borrowed under the Credit Facility.

The Company intends to continue to pursue acquisition opportunities and may be
in various stages of negotiation, due diligence and documentation of potential
acquisitions at any time.  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 working capital, cash
flow from operations and borrowings, including any unborrowed portion of the
Credit Facility, as well as issuances of additional equity.  To the extent the
Company funds a significant portion of the consideration for future acquisitions
with cash, it may have to increase the amount of the Credit Facility or obtain
other sources of financing, including the issuance of



                                       22
<PAGE>   25
additional debt or equity.  Capital expenditures for equipment and expansion of
facilities are expected to be funded from cash flow from operations and
supplemented as necessary by borrowings under the Credit Facility.

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 generally 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 new construction projects and 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.

INFLATION

Due to the relatively low levels of inflation experienced in fiscal 1995, 1996,
and 1997, inflation did not have a significant effect on the results of the
company in those fiscal years, or any of the Acquired Companies during similar
periods.

RECENT ACCOUNTING PRONOUNCEMENTS

Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation," allows entities to choose between a new fair value
based method of accounting for employee stock options or similar equity
instruments and the current intrinsic, value-based method of accounting
prescribed by Accounting Principles Board Opinion No. 25 ("APB No. 25").
Entities electing to remain with the accounting in APB No. 25 must make pro
forma disclosures of net income and earnings per share as if the fair value
method of accounting had been applied. The Company will provide pro forma
disclosure of net income and earnings per share, as applicable, in the notes to
future consolidated annual financial statements.

In June, 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" which establishes standards for the way
public enterprises are to report information about operating segments in annual
financial statements and requires the reporting of selected information about
operating segments in interim financial reports issued to shareholders.  SFAS
No. 131 also establishes standards for related disclosures about products and
services, geographic areas, and major customers.  SFAS No. 131 is effective for
fiscal years beginning after December 15, 1997, at which time the Company will
adopt the provision.  This statement is not anticipated to have a material
impact on the Company's financial disclosures.

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, and 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.

In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
131, "Disclosure about Segments of an Enterprise and Related Information,"
which establishes standards for the way public enterprises are to report
information about operating segments in annual financial statements and
requires the reporting of selected information about operating systems in
interim financial reports issued to shareholders.  SFAS No. 131 is effective
for the Company for its year ended September 30, 1999, at which time the
Company will adopt the provision.  The Company is currently evaluating the
impact on the Company's financial disclosures.

In February 1998, the FASB issued SFAS No. 132, "Employers Disclosures about
Pensions and Other Retirement Benefits," which becomes effective for financial
statements for the year ended September 30, 1999.  SFAS No. 132 requires
revised disclosures about pension and other postretirement benefit plans.  The
Company is currently assessing the impact of this statement on its annual
financial statements.

On June 1, 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which becomes effective for the Company
for its year ended September 30, 2000.  SFAS No. 133 requires a company to
recognize all derivative



                                       23
<PAGE>   26

instruments (including certain derivative instruments embedded in other
contracts) as assets or liabilities in its balance sheet and measure them at
fair value.  The statement requires that changes in t he derivatives fair value
be recognized currently in earnings unless specific hedge accounting criteria
are met.  The Company is evaluating SFAS No.  133 and the impact on existing
accounting policies and financial reporting disclosures.  However, the Company
has not to date engaged in activities or entered into arrangements normally
associated with derivative instruments.

YEAR 2000 DATE CONVERSION

The Company is in the process of identifying and evaluating potential issues
for its information technology and third party relationships associated with
the date change in the year 2000.  The Company has not yet fully assessed any
Year 2000 remedial costs, but is in the process of identifying and developing
solutions to the Year 2000 issues.  While the Company is not currently able to
quantify the cost of corrective actions, it does not expect that these actions
will materially exceed the cost of normal software upgrades and replacements
expected to occur through the year 2000.  While the Company believes all
necessary work will be completed in a timely fashion, it cannot guarantee that
the systems of other companies on which the Company relies will be converted
within the same timeframe.  The Company is attempting to obtain assurances from
vendors, business partners, and others with which it conducts business that
their systems will be Year 2000 compliant.  If as a result of foregoing process
the Company determines that a material business interruption may occur due to
the Year 2000 issue, it will attempt to implement an appropriate contingency
plan.

MILLS RESULTS OF OPERATIONS

  Mills, headquartered in Dallas, Texas was founded in 1972 and operates
primarily in the greater Dallas-Fort Worth area. Mills derives a significant
portion of its revenues from higher margin design-and-build services and from
data cabling and fire alarm systems.

  The following table sets forth selected statement of operations data as a
percentage of revenues for the periods indicated:

  Mills results for the year ended September 30, 1997 compared to the year ended
December 31, 1996

  Revenues increased $9.0 million, or 14%, from $65.4 million for the year
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 in the
Fort 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.

 Mills results for the nine months ended September 30, 1997 compared to nine
months ended September 30, 1996

  Revenues increased $8.9 million, or 21%, 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 Fort 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.

 Mills results for the year ended December 31, 1996 compared to the year ended
December 31, 1995

  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
30% increase in maintenance and service revenues resulting from Mills' focus on
increasing its maintenance and service revenues.

  Gross profit increased $7.0 million, or 89%, from $7.9 million for the year
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.

 Muth results for the year ended September 30, 1997 compared to the year ended
December 31, 1996

  Revenues increased $2.0 million, or 12%, from $16.8 million for the fiscal
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
23% from 24% over these periods.

 Muth results for the nine months ended September 30, 1997 compared to nine
months ended September 30, 1996

  Revenues increased $2.0 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 $0.2 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 attributable 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.

 Muth results for the year ended December 31, 1996 compared to the year ended
December 31, 1995

  Revenues increased $0.8 million, or 5%, from $16.0 million for the year ended
December 31, 1995 to $16.8 million for the year ended December 31, 1996, due to
increased market demands for electrical contracting services, slightly offset
by delays caused by the harsh winter, 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 attributable to increased
margins on service work in 1996 and increased revenues.

  Selling, general and administrative expenses remained constant over these
periods.

  Revenues increased $2.5 million, or 18%, from $13.9 million for the year
ended December 31, 1996 to $16.4 million for the year ended September 30, 1997,

and gross margin increases in 1997 when compared to 1996 are attributable to an
increase in the overall demand, as well as demand for higher margin retail
construction contracts.

contracting and maintenance services.  Subsequent to its IPO, and through
September 11, 1998, the Company has acquired 19 additional electrical
contracting and maintenance businesses.  Of these 19 Post IPO Acquisitions, 18
were accounted for using the purchase method of accounting and one was
accounted for using the pooling of interests method of accounting.  IES has





                                       44

acquired 35 electrical contracting and maintenance service companies with pro
forma combined revenues of $705.0 million and $553.3 million for the year ended
September 30, 1997 and the nine months ended June 30, 1998, respectively, making
the Company one of the largest providers of electrical contracting and
maintenance services in the United States. Of such fiscal 1997 pro forma
revenues, approximately 80% was derived from commercial approximately 46% and
industrial approximately 34% contracting, approximately 14% was derived from
residential contracting and approximately 6% was derived from electrical
maintenance work. Combined revenues of the Companies, which have been in
business an average of 21 years, increased at an average compound annual
growth rate of approximately 17% from fiscal 1995 through 1997.

  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 Companies specialize in either commercial and industrial or
residential work, although a few of the 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 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





                                       45
<PAGE>   48
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 service 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, 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. 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 1995 through 1997, the Companies revenues from electrical
contracting for commercial and industrial customers have grown at an average
compound annual rate of approximately 17% 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





                                       46
<PAGE>   49
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 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 Companies residential electrical contracting revenues have grown
at an average compound annual rate of approximately 19% from fiscal 1995
through 1997.

  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 has 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
provides increased efficiency in materials purchasing, computer system
development, employee benefits, bonding, insurance and financing. The Company
believes that the diversity of its operations diminishes the effects of
regional and market downturns, offers opportunities to pursue growth in its
existing markets and creates a base of expertise to expand into new markets and
serve new customers.

  The Company leverages 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 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





                                       47
<PAGE>   50
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 Companies are
members of the IEC and other trade organizations, and the Company has
implemented programs to share best practices among the Companies and 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 Acquired 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 Companies. The Company identifies and shares 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 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 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  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 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





                                       48
<PAGE>   51
   entrepreneurial spirit present in each of the Companies. The Company also
   structured to allow it to capitalize on the considerable local and regional
   market knowledge and customer relationships possessed by each of the
   Companies, 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 of the Companies provide
   competitive advantages in this regard. The Company attracts and develops
   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 have been
   centralized. In addition, by combining overlapping operations of certain of
   the Companies, the Company expects to realize savings in overhead and other
   expenses. The Company uses 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
   additional 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 Acquired Companies. At some
   locations, the larger combined workforce provides 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
focuses 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 maintenance service businesses that lack the capital
necessary to expand operations will become acquisition candidates. For these
acquisition candidates, the Company  provides (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 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 pursues 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





                                       49
<PAGE>   52
   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
   seeks 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 maintains
   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.





                                       50
<PAGE>   53
  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 services. 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.

  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
revenues for the year ended September 30, 1997. As a result of emphasis on
quality and worker reliability, management and a dedicated sales and work force
at the Companies have been responsible for developing and maintaining
successful relationships with key customers. Customers of the 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.

   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





                                       51
<PAGE>   54
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 of the Companies 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 has centralized its consolidated accounting and financial
reporting activities at its operational headquarters in Houston, Texas, while
basic accounting activities are 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 owned and leased service trucks, vans and
support vehicles. It believes these vehicles generally are adequate for the
Company's current operations.

  At September 14, 1998, the Company maintained warehouses, sales facilities
and administrative offices at 76 locations.  Substantially of the Company's
facilities are leased. The Company leases its corporate headquarters located in
Houston, Texas.

  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





                                       52
<PAGE>   55
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. See "Risk Factors -- Competition."

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 11, 1998, the Company had approximately 8,141 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 has entered 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" (i) by the employee upon thirty days' written notice or (ii) by
the Company upon approval of 51% of the Board of Directors. 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 the greater of (i) three years' base salary or (ii) the base
salary for whatever period is then remaining on the initial term 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.





                                       58

  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 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.
See "Management -- Directors and Executive Officers" for the composition of the
Compensation Committee following the consummation of the Offerings. 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





                                       59
<PAGE>   62
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 150,000 shares of Common Stock have been granted to each of
Mr. Wise and Mr. Wombwell.  The options granted to Messrs. Wise and Wombwell
have an exercise price equal to 60% of the initial public offering price per
share in the offering. 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, other than due to death or disability or (iii) one year
following a termination of employment due to death or disability. In addition,
options can be granted to a non-employee director upon such terms as the Board
determines, whenever it believes such additional grant is appropriate. The
maximum number of shares of Common Stock that may be subject to outstanding
awards determined immediately after the grant of any award is 250,000.

                              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

trustees of the trusts are independent third parties not subject to control by
Mr. Snyder. In September 1997, IES issued an additional 442,589 shares to Mr.

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. The initial $1 million of such advances bore interest at 8.5%, and
additional advances bore interest at LIBOR plus 1.5%. All of Mr. Snyder's
advances were repaid from the net proceeds of the Offering.

  The Company has issued a total of 1,396,602 shares of Common Stock at $.01

indirectly, in real property to Mr. Weik and his immediate family. It is
anticipated that such real estate will be leased to the Company for an annual
rent of approximately $150,000. The Company believes that such rent is not in
excess of fair rental value for such facilities.

  Pollock leases certain real property from Mr. Pollock. Amounts paid pursuant
to this lease were $20,000 for fiscal 1995, $36,000 for fiscal 1996 and $36,000
for fiscal 1997.

  Since January 1, 1996, Mr. Muth has from time to time incurred indebtedness
from Muth, of which the largest aggregate amount outstanding at any time was
$205,000. All amounts owed by Mr. Muth to Muth will be repaid prior to the
closing of the Offerings. Mr. Muth is a director of the Company.

  Prior to the closing of the Acquisitions and the consummation of the
Offerings, certain assets of Muth will be purchased by Mr. Muth for $217,140.

  From time to time in the past Muth has completed electrical contracts for
Muth Properties, L.L.C., a limited liability company of which Mr. Muth is a
member. Total electrical contracts completed by Muth for Muth Properties,
L.L.C. were $82,731 for 1995, $82,032 for 1996 and $120,915 for the six months
ended June 30, 1997. Prior to the closing of the Acquisitions and the
consummation of the Offerings, a final payment of $162,900 will be made by Muth
Properties, L.L.C.  to Muth.

  Prior to July 1, 1997, Muth leased certain real property from Mr. Muth, d/b/a
D & D Properties. Lease payments made by Muth to Mr. Muth totaled $80,725 for
1994, $95,180 for 1995, $118,088 for 1996 and $56,906 for the six months ended
June 30, 1997. Effective July 1, 1997, Muth Properties, L.L.C. became the
lessor of these properties. It is anticipated that annual rentals paid to Muth
Properties, L.L.C. by Muth will be approximately $120,000.

   Stalvey Rentals, a general partnership of which Mr. Stalvey is a member, is
presently constructing a new facility to lease to Ace in Valdosta, Georgia and
an inducement letter has been executed regarding Ace's commitment to lease the
new facility for a period of 20 years beginning as soon as a certificate of
occupancy is obtained. Ace entered into a five year lease, with a five year
option period, with Mr. Stalvey and his brother. Initial annual rent on this
facility is $103,200, without respect to property taxes and insurance. Mr.
Stalvey is a director of the Company.

  In addition to the transactions described above, certain of the Founding
Companies have entered into lease agreements with parties related to the
Company, for rents that the Company believes are not in excess of fair rental
value.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

  The Company's authorized capital stock consists of 100,000,000 shares of
Common Stock, par value $0.01 per share, 2,655,709 shares of Restricted Common
Stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par
value $0.01 per share. As of September 11, 1998,  30,756,875 shares of Common
Stock and Restricted Common Stock are issued and outstanding. The following
summary of the terms and provisions of the Company's capital stock does not
purport to be complete and is qualified in its entirety by reference to the
Company's Amended and Restated Certificate of Incorporation and Bylaws, which
have been filed as exhibits to the Company's registration statement, of which
this Prospectus is a part, and applicable law.

COMMON STOCK AND RESTRICTED COMMON STOCK

  The holders of Common Stock are entitled to one vote for each share on all
matters voted upon by stockholders, including the election of directors. Such
holders are not entitled to vote cumulatively for the election of directors.
Holders of a majority of the shares of Common Stock entitled to vote in any
election of directors may elect all of directors standing for election.

  The holders of Restricted Common Stock, voting together as a single class,
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.  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.





                                       66
<PAGE>   69
  Each share of Restricted Common Stock will automatically convert to Common
Stock on a share-for-share basis 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)).

  The Common Stock is listed on the NYSE under the symbol "IEE." The Restricted
Common Stock is not 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 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





                                       67
<PAGE>   70
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 directors' and officers' liability insurance.
The foregoing provisions may extend to liabilities arising due to violations of
the federal securities laws. It is the position of the Securities and Exchange
Commission (the "Commission") that indemnification for liabilities under the
Securities Act is against public policy and is, therefore, unenforceable.

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.





                                       68
<PAGE>   71
  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,
2,655,709 shares of Restricted Common Stock, and 10,000,000 shares of preferred
stock. Any 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





                                       69
<PAGE>   72
made). The notice must contain certain 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. As of September
11, 1998, 28,101,166 shares of Common Stock and 2,655,709 shares of Restricted
Common Stock were issued and outstanding. Of such shares, 13,923,675 shares of
Common Stock and all of the shares of Restricted Common Stock were issued in a
transaction not registered under the Securities Act,





                                       70
<PAGE>   73
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 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 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.

  Prior to the Offering, there was 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 aggregate, these
groups hold 16,365,336 shares of Common Stock and Restricted 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 do not apply
to the registration statement containing this Prospectus or to any registration
statement filed with respect to employee benefit plans.

<PAGE>   74
                              PLAN OF DISTRIBUTION

  This Prospectus may be used by the Company for the offer and sale of up to
21,000,000 shares of Common Stock from time to time in connection with the
acquisition of other businesses, assets or securities in business combination
transactions. The consideration offered by the Company in such acquisitions, in
addition to any shares of Common Stock offered by this Prospectus, may include
assets, debt or other securities or assumption by the Company of liabilities of
the business being acquired, or a combination thereof. The terms of
acquisitions are typically determined by negotiations between the Company and
the owners of the businesses, assets or securities to be acquired, with the
Company taking into account the quality of management, the past and potential
earning power and growth of the businesses, assets or securities to be
acquired, and other relevant factors. Shares of Common Stock issued to the
owners of the businesses, assets or securities to be acquired are generally
valued at a price reasonably related to the market value of the shares of
Common Stock either at the time the terms of the acquisition are tentatively
agreed upon or at or about the time or times of added delivery of the shares of
Common Stock.

                                 LEGAL MATTERS

  Certain legal matters in connection with the Common Stock being offered
hereby will be passed upon for the Company by John F. Wombwell, Esq., Senior
Vice President, General Counsel and Secretary of the Company.  Mr. Wombwell

                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 16
companies and related entities engaged in all facets of electrical contracting
and maintenance services on January 30, 1998 (together, the Founding Companies),
and related transactions, (ii) IES's January 30, 1998, initial public offerings
in the United States and Canada and outside the United States and Canada
(including the underwriters exercise of the overallotment option for 1,050,000
shares) (the "Offering"), and (iii) the acquisitions of 19 additional electrical
contracting and maintenance businesses from April 1998 through September 11,
1998 (the "Post IPO Acquisitions"). Of these Post IPO Acquisitions, 18 were
accounted for using the purchase method of accounting and one was accounted for
using the pooling-of-interests method of accounting. The Founding Company
Acquisitions and the Post IPO Acquisitions are collectively referred to as the
"Companies". The Founding Company Acquisitions occurred simultaneously with the
closing of the Offering and were accounted for using the purchase method of
accounting. Pursuant to the Securities and Exchange Commission's ("SEC") Staff
Accounting Bulletin No. 97 (SAB97), Houston-Stafford Electric, Inc. ("HSE") is
for accounting purposes considered the entity which acquired the other Founding
Companies and IES (the "Accounting Acquirer"). As such, IES's consolidated
historical financial statements represent the financial position and results of
operations of (i) HSE as restated to include the financial position and results
of operations of the Pooled Company, and (ii) the other Founding Companies and
the Post IPO Acquisitions beginning on their respective dates of acquisition.

    The unaudited pro forma combined balance sheet gives effect to the 8 Post
IPO Acquisitions which were acquired subsequent to June 30, 1998, and related
transactions as if they had occurred on June 30, 1998. 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 Companies have contractually agreed to prospective
changes in salary, bonuses, benefits and lease payments, these changes have been
reflected in the unaudited pro forma combined statement of operations.

    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 combined 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 combined financial position or results of operations for any future
period. Since the 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 historical financial statements and notes thereto
included elsewhere in this Prospectus. See also "Risk Factors" included
elsewhere herein.

2. ACQUISITION OF COMPANIES:

On January 30, 1998, the Company completed its initial public offering of its
stock, which involved the sale to the public of 7,000,000 shares of the
Company's common stock at $13.00 per share. The Company received net proceeds
from the Offering of approximately $78.8 million. Concurrent with the completion
of the Offering, IES acquired the Founding Companies for consideration
consisting of $53.4 million ($38.8 million excluding the cash paid to the
Accounting Acquirer) in cash and 12,313,025 shares (8,961,000 shares excluding
the shares issued to the owners of the Accounting Acquirer) of common stock.
Additionally, on February 5, 1998, the Company sold 1,050,000 shares of its
common stock pursuant to the overallotment option granted to the underwriters in
connection with the Offering for net proceeds of approximately $12.7 million.
The Company used approximately $7.6 million of the net proceeds from the
Offering to retire outstanding third party debt and approximately $16.0 million
to pay indebtedness incurred by the Founding Companies for distributions to the
owners prior to the Acquisitions. The Company used the remaining net proceeds to
fund a portion of the cash consideration for the Post IPO Acquisitions.

Subsequent to its IPO, and through June 30, 1998, the Company has acquired 11
additional electrical contracting and maintenance businesses for approximately
$30.9 million of cash and 3.5 million shares of common stock. Of these 11 Post
IPO Acquisitions, 10 were accounted for using the purchase method of accounting
and one was accounted for using the pooling-of-interests method of accounting.
Accordingly, the Company's historical financial statements have been restated to
include the historical financial statements of the Pooled Company.

Subsequent to June 30, 1998, and through September 11, 1998, the Company has
acquired eight additional electrical contracting and maintenance businesses for
approximately $63.6 million of cash (funded through borrowings under the 
Company's $175 million bank credit facility) and 2.8 million shares of 
common stock. All of those acquisitions were accounted for using the purchase 
method of accounting.

In connection with the acquisitions of the Founding Companies and the Post IPO
Acquisitions, the Company has recorded approximately $288 million of excess
total consideration paid over the net tangible assets acquired has been recorded
as goodwill in the accompanying consolidated financial statements. The
accompanying balance sheets include allocations of the respective purchase
prices initially assigned to the assets acquired and liabilities assumed based
on preliminary estimates of fair value and may be revised as additional
information concerning the valuation of such assets and liabilities becomes
available.

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 Integrated
Electrical Services, Inc., and subsidiaries as of December 31, 1996, and
September 30, 1997, and the results of their operations and their cash flows for
each of the two years in the period ended December 31, 1996, and for the year
ended September 30, 1997, in conformity with generally accepted accounting
principles.

         As discussed in Note 1, the accompanying consolidated financial
statements reflect the Company on a historical basis including Houston-Stafford
Electric, Inc., as the accounting acquirer restated for the effect of a
pooling-of-interests transaction.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  BUSINESS AND ORGANIZATION AND BASIS OF PRESENTATION:

Integrated Electrical Services, Inc. (the Company or IES), a Delaware
corporation, was founded in June 1997 to create a leading national provider and
consolidator of electrical contracting and maintenance services, focusing
primarily on the commercial, industrial and residential markets. On January 30,
1998, concurrent with the closing of its initial public offering (IPO or
Offering) of common stock, IES acquired, in separate transactions, for
consideration including $53.4 million of cash and 12,313,025 shares of common
stock, 16 companies and related entities engaged in all facets of electrical
contracting and maintenance services (collectively, the Founding Companies or
the Founding Company Acquisitions).

For financial statement presentation purposes, Houston-Stafford Electric, Inc.
(Houston-Stafford), one of the Founding Companies, has been identified as the
accounting acquirer. The acquisition of the remaining Founding Companies and IES
was accounted for using the purchase method of accounting. The allocation of
purchase prices to the assets acquired and liabilities assumed has been
initially assigned and recorded based on preliminary estimates of fair value and
may be revised as additional information concerning the valuation of such assets
and liabilities becomes available.

Subsequent to its IPO, and through June 30, 1998, the Company acquired 11
additional electrical contracting and maintenance businesses for approximately
$30.9 million of cash and 3,519,023 shares of common stock (the Post IPO
Acquisitions). Of these 11 Post IPO Acquisitions, 10 were accounted for using
the purchase method of accounting (the Purchased Companies) and one was
accounted for using the pooling-of-interests method of accounting (the Pooled
Company) resulting in a restatement of the Company's financial statements for
all periods presented (see Note 3).

The accompanying consolidated financial statements through January 30, 1998,
reflect the historical accounts of Houston-Stafford as the accounting acquirer.
The historical financial statements have been restated for all periods presented
for the effect of the acquisition accounted for as a pooling-of-interest. The
Founding Companies are included in the Company's results of operations beginning
February 1, 1998, and the Purchased Companies beginning on their respective
dates of acquisition. Houston-Stafford's results of operations through January
30, 1998, include a non-cash, non-recurring compensation charge of approximately
$17.0 million required by the Securities and Exchange Commission (SEC) in
connection with a note receivable and rights held by an officer of
Houston-Stafford which was exchanged for cash and shares of IES common stock in
connection with the Founding Company Acquisitions (see Note 10). The Company has
changed from a calendar to a September fiscal year.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation

The accompanying consolidated financial statements after January 30, 1998,
include the accounts of IES and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


Interim Financial Information

The interim financial statements for the nine months ended June 30, 1997 and
1998, and the nine months ended September 30, 1997, are unaudited and have been
prepared pursuant to the rules and regulations of the SEC. 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 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 $219,000 and $304,000 for the years ended December 31, 1995 and
1996, and $391,000 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.

Goodwill

Goodwill represents the excess of the aggregate of purchase price paid by the
Company in the acquisition of businesses accounted for as purchases over the
fair market value of the net assets acquired. Goodwill is amortized on a
straight-line basis over 40 years. As of September 30, 1997, accumulated
amortization was approximately $33,000.

The Company periodically evaluates the recoverability of intangibles resulting
from business acquisitions and measures the amount of impairment, if any, by
assessing current and future levels of income and cash flows as well as other
factors, such as business trends and prospects and market and economic
conditions.

Debt Issue Costs

Debt issue costs related to the Company's credit facility (see Note 6) are
included in other noncurrent assets and are amortized to interest expense over
the scheduled maturity of the debt.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


Revenue Recognition

The Company recognizes revenue when services are performed except when work is
being performed under a construction contract. Such contracts generally provide
that the customers accept completion of progress to date and compensate the
Company for services rendered measured in terms of hours expensed or some other
measure of progress. Revenues from construction contracts are recognized on the
percentage-of-completion method generally 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 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, 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.

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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



Income Taxes

The Company follows the asset and liability method of accounting for income
taxes in accordance with 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 13 for discussion of
significant estimates reflect in the Company financial statements.

New Accounting Pronouncements

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 consolidated financial position or results of
operations of the Company.

In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information,"
which establishes standards for the way public enterprises are to report
information about operating segments in annual financial statements and requires
the reporting of selected information about operating segments in interim
financial reports issued to shareholders. SFAS No. 131 is effective for the
Company for its year ended September 30, 1999, at which time the Company will
adopt the provision. The Company is currently evaluating the impact on the
Company's financial disclosures.

In February 1998, the FASB issued SFAS No. 132, "Employers Disclosures about
Pensions and Other Postretirement Benefits," which becomes effective for
financial statements for the year ended September 30, 1999. SFAS No. 132
requires revised disclosures about pension and other postretirement benefit
plans. The Company is currently assessing the impact of this statement on its
annual financial statements.

On June 1, 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which becomes effective for the Company for
its year ended September 30, 2000. SFAS No. 133 requires a company to recognize
all derivative instruments (including certain derivative instruments embedded in
other contracts) as assets or liabilities in its balance sheet and measure them
at fair value. The statement requires that changes in the derivatives fair value
be recognized currently in earnings unless specific hedge accounting criteria
are met. The Company is evaluating SFAS No. 133 and the impact on existing
accounting policies and financial reporting disclosures. However, the Company
has not to date engaged in activities or entered into arrangements normally
associated with derivative instruments.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


Earnings per Share

The Company has adopted SFAS No. 128, "Earning Per Share," which requires
restatement of all comparative per share amounts. Under the provisions of SFAS
No. 128, the presentation of primary earnings per share has been replaced with
earnings per share for potentially dilutive securities such as outstanding
options. All prior period earnings per share data have been restated.

For financial statement purposes as required by the rules and regulations of the
Securities Act, Houston-Stafford has been identified as the accounting acquirer
in the transaction with IES and its initial public offering. As such the shares
of IES beneficially owned by the shareholders of Houston-Stafford and the shares
issued in the pooling transaction have been used in the calculation of basic and
diluted earnings per share of the Company, for all periods prior to the IPO.

3.  BUSINESS COMBINATIONS:

On January 30, 1998, concurrent with the closing of its IPO, IES acquired, in
separate transactions, for consideration including $53.4 million of cash and
12,313,025 shares of common stock, 16 companies and related entities engaged in
all facets of electrical contracting and maintenance services. Subsequent to its
IPO, and through June 30, 1998, the Company has acquired 11 additional
electrical contracting and maintenance businesses for approximately $30.9
million of cash and 3.5 million shares of common stock. Of these 11 Post IPO
Acquisitions, 10 were accounted for using the purchase method of accounting and
the Pooled Company was accounted for using the pooling-of-interests method of
accounting. Accordingly, the Company's historical financial statements have been
restated to include the historical financial statements of the Pooled Company.

Pooling

On June 1, 1998, IES completed the acquisition of all the capital stock of H.R.
Allen, Inc. (Allen), in a business combination accounted for as a
"pooling-of-interests" transaction in accordance with the requirements of APB
No. 16. Allen, headquartered in Charleston, South Carolina, provides electrical
contracting and maintenance services. IES issued 1,140,000 shares of common
stock in exchange for all of the capital stock of Allen. There were no
transactions between IES, or Allen during periods prior to the business
combination.

The following table summarizes the unaudited restated revenues, net income and
per share data of the Company after giving effect to the Pooled Company (in
thousands, except per share data).

Purchases

The total consideration paid for the Purchased Companies through June 30, 1998,
was approximately $73.0 million (including assumed debt of approximately $5.2
million). The $53.7 million excess of the total consideration paid over the net
tangible assets acquired has been recorded as goodwill in the accompanying
consolidated financial statements. The accompanying June 30, 1998, consolidated
balance sheet includes allocations of the respective purchase prices to the
assets acquired and liabilities assumed based on preliminary estimates of fair
value and are subject to final adjustment.

The unaudited pro forma data presented below reflect the results of operations

Credit Facility

In January 1998, the Company obtained a credit facility from a commercial bank.
The credit facility is a three-year revolving credit facility of up to $65
million to be used for working capital, capital expenditures, other corporate
purposes and acquisitions. In August, the Company increased the credit facility
to $175.0 million. The credit facility matures July 30, 2001. Amounts borrowed
under the credit facility bear interest at an annual rate equal to either (a)
the London interbank offered rate (LIBOR) plus 1.0 percent to 2.0 percent, as
determined by the ratio of the Company's total funded debt to EBITDA (as defined
in the credit facility) or (b) the higher of (i) the bank's prime rate and (ii)
the Federal funds rate plus 0.5 percent plus up to an additional 5 percent, as
determined by the ratio of the Company's total funded debt to EBITDA. Commitment
fees of 0.25 percent to 0.375 percent, as determined by the ratio of the
Company's total funded debt to EBITDA, will be due on any unused borrowing
capacity under the credit facility. The Company's existing and future
subsidiaries

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


guarantee the repayment of all amounts due under the facility, and the facility
is secured by the capital stock of those subsidiaries and the accounts
receivable of the Company and those subsidiaries. The credit facility requires
the consent of the lenders for acquisitions exceeding a certain level of cash
consideration, prohibits the payment of cash dividends on the common stock,
restricts the ability of the Company to incur other indebtedness and requires
the Company to comply with various affirmative and negative covenants including
certain financial ratios. As of September 11, 1998, $42 million was borrowed
under the credit facility.

7.  LEASES:

The Company leases various facilities, at which it conducts its operations,
under noncancelable operating leases. For a discussion of leases with certain
related parties see Note 10.

9.  STOCKHOLDERS' EQUITY:

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 upon
disposition by the holder of such shares.

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 percent 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 has filed a registration statement
on Form S-8 under the Securities Act of 1933 registering the issuance of shares
upon exercise of options granted under this Plan. Options generally vest at the
rate of 20 percent per year, commencing on the first anniversary of the grant
date and will expire 10 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.

Director's 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 nonemployee directors. The number of
shares authorized and reserved for issuance under the Directors' Plan is 260,000
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 Offerings.

Each nonemployee director was 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
have an exercise price based on the fair market value at the date of grant and
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.

As of September 11, 1998, the Company had total outstanding options under these
Plans to purchase up to a total of approximately 3,110,550 shares of common
stock.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


Initial Public Offering

On January 30, 1998, the Company completed its initial public offering, issuance
to the public 7,000,000 shares of its common stock at a price of $13.00 per
share, resulting in net proceeds to the Company of $78.8 million after deducting
underwriting commissions and discounts. On February 5, 1998, the Company sold
1,050,000 shares of common stock pursuant to the overallotment option granted to
the underwriters. The Company realized net proceeds from the sale of $12.7
million.

10. RELATED-PARTY TRANSACTIONS:

The Company has transactions in the normal course of business with certain
affiliated companies. Amounts due from related parties at December 31, 1996, and
September 30, 1997, were $338,000 and $309,000.

The Company leases certain real properties from certain related parties. The
annual rentals for 1995, 1996 and for the year ended September 30, 1997,
approximated $210,000, $291,000 and $216,000, respectively.

In August 1996, the Company negotiated the purchase of the stock from an
officer. The selling price of the shares totaled $800,000. The Company signed an
installment promissory note that provided for the payout of $800,000 over seven
years at 8 percent interest, secured by the purchased stock. Subsequent to the
August 1996 transaction, the executive remained an officer of the Company and
was paid cash compensation of approximately $372,000 during the last four months
of 1996 and approximately $252,000 during the first nine months of 1997. These
amounts have been reflected as compensation expense in the accompanying income
statements for the applicable periods. At the closing of the IPO, the officer
exchanged the promissory note for cash and shares of IES common stock. In
connection therewith, the Company recorded a non-cash, non-recurring
compensation charge of approximately $17.0 million.

11.  EMPLOYEE BENEFIT PLANS:

Certain subsidiaries of the Company provide various defined contributions
savings plans for their employees (the Plans). The Plans cover substantially all
full-time employees of such subsidiaries. Participants vest at varying rates
ranging from full vesting upon participation to those that provide for vesting
to begin after three years of service and are fully vested after seven years.
Certain plans provide for a deferral option that allows employees to elect to
contribute a portion of their pay into the plan and provide for a discretionary
profit sharing contribution by the individual subsidiary. Generally the
subsidiaries match a portion of the amount deferred by participating employees.
Contributions for the profit sharing portion of the plan are generally at the
discretion of the individual subsidiary board of directors. The aggregate
contributions to the Plans were $50,000, $75,000 and $100,000 for the years
ended December 31, 1995 and 1996, and September 30, 1997.

12.  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.

13.  COMMITMENTS AND CONTINGENCIES:

Litigation

Subsidiaries of the Company are involved in various legal proceeds that have
arisen in the ordinary course of business. While it is not possible to predict
the outcome of such proceedings with certainty, in the opinion of the Company's
management, all such proceedings are either adequately covered by insurance or,
if not so covered should not ultimately result in any liability which would have
a material adverse effect on the financial position, liquidity or results of
operations of the Company.

Insurance

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

14.  RISK CONCENTRATION:

Financial instruments, which potentially subject the Company to concentrations
of credit risk consist principally of cash deposits and trade accounts
receivable. The Company grants credit, generally without collateral, to its
customers, which are generally contractors and home builders throughout the
United States. Consequently, the Company is subject to potential credit risk
related to changes in business and economic factors throughout the United States
within the construction and home-building market. However, the Company generally
is entitled to payment for work performed and has certain lien rights in that
work. Further, 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.

period from October 1, 1997 through January 30, 1998. 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 audit.

    We conducted our audit 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 audit provides 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 Integrated Electrical
Services, Inc. as of September 30, 1997, and the results of its operations and
its cash flows for the period from inception (June 26, 1997) through September

                      INTEGRATED ELECTRICAL SERVICES, INC.

                          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. The Company has elected a September fiscal
year.

    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 founder and current primary stockholder, on
behalf of the Company. The Company's founder and primary stockholder has also
committed to fund future organization expenses and offering costs. As of
September 30, 1997 and January 30, 1998, costs of approximately $1,560,000 and
$2,868,000, respectively, have been incurred in connection with the Offerings,
and such costs will be a reduction of the proceeds from the Offerings. IES has
treated these costs as deferred offering costs in the accompanying balance sheet
and statements of cash flows. IES utilized proceeds from the Offerings to
execute the Acquisitions and to repay its current primary stockholder for
funding deferred offering costs. 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".

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire year.

2. STOCKHOLDERS' EQUITY:

Common Stock and Preferred Stock

    In connection with the organization and initial capitalization of IES, the
Company issued 2,329,600 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 1,722,711 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 Chairman of the Board, and certain trusts established for the
benefit of his children, 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 $13.6
million, calculated based on the fair value of such shares which has been
determined to be $9.10 and $9.80 per share (a discount of 35% and 30%,
respectively, from the estimated initial public offering price) for the shares
issued in June 1997 and September 1997, respectively. The fair value of such
shares was based on specific factors related to the Company and the transaction
including restrictions on transferability and sale, the time value of money
during the holding period and the substantive progress of the transaction at
each issuance date. The nonrecurring compensation charge discussed above does
not include any of the shares issued to the founder and chairman of the board,
and certain trusts established for the benefit of his children. The shares
issued to the founder and Chairman of the Board, and such trusts, will be
reflected as acquisition costs in connection with the Acquisitions.

    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.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED


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 upon
disposition by the holder of such shares.

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 filed a
registration statement on Form S-8 under the Securities Act of 1933 registering
the issuance of shares upon exercise of options granted under this Plan. The
Company granted 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 nonemployee directors. 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 Offerings.

    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 and warrants. Diluted earnings per share will be
computed including the impacts of all potentially dilutive securities. The
Company adopted 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 shares, and conversion
and exercise prices. The Company adopted 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
did not have a material impact on the Company or its financial disclosures, as
the Company currently did not enter into any material transactions which result
in charges (or credits) directly to equity (such as additional minimum pension
liability changes, currency translation adjustments, and unrealized gains and
losses on available for sale securities).

5. FOUNDING COMPANY ACQUISITIONS:

    IES acquired the following entities (the Founding Companies) on January 30,
1998 contemporaneously with the initial public offering. The entities 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.

    The aggregate consideration that was paid by IES to acquire the Founding
Companies was approximately $53.4 million in cash and 12.3 million shares of
Common Stock. Additionally, approximately 3.9 million of the 4.1 million shares
issued to the IES founder and Chairman of the Board and certain trusts, and
certain other management, were reflected as acquisition costs as part of the
acquisition transactions.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

    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. BANK CREDIT FACILITY

    The Company entered into a credit facility with a commercial bank. The
credit facility is a three-year revolving credit facility of up to $70 million
to be used for working capital, capital expenditures, other corporate purposes
and acquisitions.

    On August 7, 1998, the Company increased its three-year revolving credit
facility with NationsBank of Texas, N.A. as agent (the "Credit Facility") from
$70.0 million to $175.0 million. The Credit Facility matures on July 30, 2001,
bears interest at the bank's prime rate or LIBOR, at the Company's option, plus
an applicable margin based on the ratio of debt to EBITDA (as defined). An
annual commitment fee from 0.25% to 0.375% is payable on any unused portion of
the Credit Facility. The Company's subsidiaries have guaranteed the repayment of
all amounts due under the facility, and the facility is secured by the capital
stock of the guarantors and the accounts receivable of the Company and the
guarantors.

    The Credit Facility will be used to fund acquisitions, capital expenditures
and working capital requirements. Under the terms of the Credit Facility the
Company is required to comply with various affirmative and negative covenants
including: (i) the maintenance of certain financial ratios, (ii) restrictions on
additional indebtedness, and (iii) restrictions on liens, guarantees and
dividends.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Mills Electrical Contractors, Inc.:

    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 and for the period from October 1, 1997 through January 30,
1998. 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 and for the period from October 1, 1997 through January 30,
1998, in conformity with generally accepted accounting principles.

                                                             ARTHUR ANDERSEN LLP

                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. 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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Interim Financial Information

    The interim consolidated 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 consolidated
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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of Securities and Exchange Commission's Staff Accounting Bulletin
No. 80 and are not necessarily indicative of the results to be expected for the
entire 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, net of an allowance for
obsolescence, 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 and
amortization expense was $179,000, $253,000, $385,000, $637,000 and $245,000 for
the years ended December 31, 1994, 1995 and 1996 and September 30, 1997 and for
the period from October 1, 1997 through January 30, 1998, 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 the purchase of 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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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.


                                      F-45
<PAGE>   121

    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 consolidated 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 Offerings.

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 consolidated 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.

</TABLE>


    Contract revenues from CIMA were approximately $250,000 and payments under
operating leases with officers of the Company were approximately $78,000 for the
period from October 1, 1997 through January 30, 1998. Additionally, the Company
has guaranteed an officer note at a bank with an outstanding balance of
approximately $125,000 at September 30, 1997. 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 and for the period from October 1, 1997 through January 30, 1998 were
$186,000, $450,000, $789,000, $789,000 and $275,000, respectively.

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.


                                      F-49
<PAGE>   125

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. The Company did
not have sales greater than 10 percent of total sales to any one customer during
the period from October 1, 1997 through January 30, 1998.

    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 and
for the period from October 1, 1997 through January 30, 1998. 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 and
for the period from October 1, 1997 through January 30, 1998, in conformity with
generally accepted accounting principles.

                     BW CONSOLIDATED, INC. AND SUBSIDIARIES

                   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 Consolidated
Subsidiary" in the accompanying consolidated financial statements.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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 employee of
CEC. The Company has changed from a calendar to a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire year.

</TABLE>

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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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.


                                      F-57
<PAGE>   133

    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 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 Offerings (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 consolidated financial position or results of operations
of the Company.

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 consolidated 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 consolidated
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.

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.

To Muth Electric, Inc.:

    We have audited the accompanying balance sheets of Muth Electric, Inc., a
South Dakota 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 each of the three years in the period ended December 31, 1996 and for
the year ended September 30, 1997 and for the period from October 1, 1997
through January 30, 1998. 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 Muth Electric, Inc., as of
December 31, 1995 and 1996 and September 30, 1997, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1996 and for the year ended September 30, 1997 and for the period
from October 1, 1997 through January 30, 1998, in conformity with generally

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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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, $212,000 and $91,000 for the years ended December 31, 1994, 1995, 1996
and September 30, 1997 and the period from October 1, 1997 through January 30,
1998, 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 

                                      F-69
<PAGE>   145
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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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
Offerings.

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 


                                      F-70
<PAGE>   146
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, $85,000 and $28,000 for the years ending
December 31, 1995, 1996 and September 30, 1997 and the period from October 1,
1997 through January 30, 1998, 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, $115,000 and $41,000 for the years ended
December 31, 1995 and 1996 and September 30, 1997 and the period from October 1,
1997 through January 30, 1998, 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 or the period from October 1, 1997 through January 30, 1998.

    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 and for the period from October 1, 1997 through January 30,
1998. 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 and for the period from
October 1, 1997 through January 30, 1998, 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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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
approximately $64,000, $107,000, $131,000 and $111,000 for the years ended
October 31, 1995 and 1996 and September 30, 1997 and for the period from 
October 1, 1997 through January 30, 1998, 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.


                                      F-78

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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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 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 


                                      F-79
<PAGE>   155
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 


                                      F-80
<PAGE>   156
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, $36,000 and $12,000 for
the years ended October 31, 1995 and 1996 and September 30, 1997 and for the 
period from October 1, 1997 through January 30, 1998, 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.

leases as recorded in short-term and long-term debt at October 31, 1996 and

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 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. During the period from October 1, 1997
through January 30, 1998, the Company had sales of approximately 25% and 12% 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.

                          NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

    Charles P. Bagby, Co., 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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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.

Supplemental Cash Flow Information (in thousands)

    The Company had the following noncash investing and financing activities
for the period from October 1, 1997 through January 30, 1998:

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 $21,000, $23,000 and $6,000 for the years ended December 31, 1996
and September 30, 1997 and the period from October 1, 1997 through January 30,
1998, 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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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.

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.

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 and for the period from October 1, 1997 through January
30, 1998. 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

                          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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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, $172,000 and $46,000
for the years ended December 31, 1995, 1996, and September 30, 1997, and for the
period from October 1, 1997 through January 30, 1998, 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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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
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.

assets. Interest is payable monthly at the bank's prime rate (8.5 percent at
September 30, 1997). The agreement stipulates a minimum interest rate of 8
percent. Any amounts available are limited to 75 percent of eligible accounts
receivable, as defined. At September 30, 1997 and December 31, 1996, the entire
amount of the line remains available to be borrowed. The line of credit is
subject to a continuing guarantee by the Company's majority stockholder. The
line of credit is due on demand, but in no event no later than July 5, 1998.

    At December 31, 1995, the maximum amount available under such line of credit
was approximately $99,000 as the Company had a $200,000 line of credit with the
bank.

6. LEASES:

    The Company leases office space from the majority stockholder under a
month-to-month operating lease. Rent expense incurred under this related-party
lease was approximately $67,000, $81,000, $83,000 and $29,000 for the years
ended December 31, 1995, 1996 and September 30, 1997 and for the period from
October 1, 1997 through January 30, 1998, respectively.

    There are no future minimum lease payments under this operating lease.

    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:

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 


                                     F-103
<PAGE>   179
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 contributions by the Company
under the plan were approximately $31,000, $44,000, $56,000 and $0 for the years
ending December 31, 1995, 1996 and September 30, 1997 and for the period from
October 1, 1997 through January 30, 1998, 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, sales of approximately 22 percent of total sales to one major customer
during the year ended September 30, 1997, and sales of approximately 51, 23 and
18 percent of total sales to three customers during the period from October 1,
1997 through January 30, 1998.

    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.

   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, and for the period from October 1, 1997 through
January 30, 1998. 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, and for the period from October 1, 1997 through
January 30, 1998, 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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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

    The Company distributed certain net assets to a stockholder of the Company 
totaling approximately $1,469,000.

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.


                                     F-110
<PAGE>   186

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 lesser of the life
of the lease or the estimated useful life of the asset. Depreciation and
amortization expense was $113,000, $125,000, $141,000 and $57,000 for the years
ended December 31, 1995, 1996 and September 30, 1997 and for the period from
October 1, 1997 through January 30, 1998, 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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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 


                                     F-111
<PAGE>   187

provision for current or deferred income taxes. The Company intends to terminate
its S Corporation status concurrently with the effective date of the Offerings.

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.

9. FINANCIAL INSTRUMENTS:

    The Company's financial instruments consist of cash and cash equivalents,

these instruments on the accompanying balance sheets approximates their fair

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 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 is self-insured for medical claims up to $14,000 per year in
total for all covered individuals. Additionally, the Company is part of the
state's workers' compensation plan and is responsible for claims up to $100,000
per accident with a maximum aggregate exposure for 24 months of $500,000. Claims
in excess of these amounts are covered by a stop-loss policy. Under the state's
policy, the Company has a $305,000 letter of credit which expires April 1, 1998.
The Company has recorded reserves for its portion of self-insured claims based
on estimated claims incurred through March 31, 1995 and 1996, December 31, 1996,
and September 30, 1997.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:

    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, sales of approximately 30 percent and
38 percent of total sales to two major customers during the year ended September
30, 1997, and sales of approximately 35 percent, 21 percent and 21 percent of
total sales to three major customers for the period from October 1, 1997 through
January 30, 1998.


    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, Incorporated (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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a March to a
September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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

     During the period from October 1, 1997 through January 30, 1998, the
Company's stockholder contributed approximately $268,000 in property and
equipment in exchange for payment of the stockholder's receivable to the 
Company.

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, $75,358 and $34,000 for the years ended March 31, 1997 and September
30, 1997 and for the period from October 1, 1997 through January 30, 1998,
respectively.


                                     F-121
<PAGE>   197

    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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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 


                                     F-122
<PAGE>   198

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.

     The receivable of $268,000 was subsequently repaid through a donation of
property and equipment from the Stockholder.

     The Company provides auto repair and restoration services to the
Stockholder. The Stockholder reimbursed the Company $81,161, $122,979 and
$27,958 for such services for the years ended March 31, 1997 and September 30,
1997 and for the period from October 1, 1997 through January 30, 1998,
respectively.

9. EMPLOYEE BENEFIT PLAN:

    The Company adopted a 401(k) savings and investment plan approved by the
Internal Revenue Service effective January 1, 1996, covering all eligible
Company employees. Contributions may be made to the plan by an employee at a
percentage of salary but cannot exceed the maximum allowed by the Internal
Revenue Code and may be matched by a discretionary Company contribution.

    The Company's contributions to the plan for the years ended March 31, 1997
and September 30, 1997 and for the period from October 1, 1997 through January
30, 1998, totaled $24,747, $24,660 and $8,751, respectively.

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 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.

12. MAJOR CUSTOMERS AND RISK CONCENTRATION:

    For the years ended March 31, 1997 and September 30, 1997, revenues from no
one individual customer exceeded 10 percent of total revenues.

    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 and for the period from October 1,
1997 through January 30, 1998. 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 and for
the period from October 1, 1997 through January 30, 1998, in conformity with
generally accepted accounting principles.

                         THURMAN & O'CONNELL CORPORATION

                          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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

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.

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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 $51,000 and $26,000
for the years ended December 31, 1995 and 1996 and September 30, 1997 and for
the period from October 1, 1997 through January 30, 1998, 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


                                     F-133
<PAGE>   209

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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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 Offerings (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


                                     F-134
<PAGE>   210

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.

3. PROPERTY AND EQUIPMENT:

    Property and equipment, at cost, consists of the following (in thousands):

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):

</TABLE>

    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.

6. RELATED-PARTY TRANSACTIONS:

    The Company earned revenue for electrical contracting services from
companies owned by a stockholder of approximately $47,000, $40,000, $25,000 and
$82,000 for the years ended December 31, 1995 and 1996, and September 30, 1997,
respectively and the period from October 1, 1997 through January 30, 1998, with
approximately $1,000, $2,000, $4,000 and $41,000 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, $8,000 and $2,000 for the years ended December 31, 1995 and 1996 and
September 30, 1997 and for the period from October 1, 1997 through January 30,
1998, 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, 1997 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 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, sales of
approximately 26, 12 and 12 percent of total sales to three major customers
during the year ended September 30, 1997 and sales of approximately 47 and 14
percent of total sales to two major customers during the period from October 1,
1997 through January 30, 1998.

    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.

                         RODGERS ELECTRIC COMPANY, INC.

                          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.

    On January 30, 1998, concurrent with the closing 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 Integrated Electrical
Services, Inc. (IES), the Company was acquired by IES. All outstanding shares of
the Company's common stock were exchanged for cash and shares of IES common
stock. 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. The Company has changed from a calendar to
a September fiscal year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Interim Financial Information

    The financial statements for the period from October 1, 1997 through January
30, 1998 are presented for purposes of complying with certain reporting
requirements of the Securities and Exchange Commission's Staff Accounting
Bulletin No. 80 and are not necessarily indicative of the results to be expected
for the entire 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 a 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 $47,000 and $18,000 for the year ended September 30, 1997 and for
the period from October 1, 1997 through January 30, 1998, 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.
Such contracts generally provide that the customers accept completion of
progress to date and compensate the Company for services rendered measured in
terms of hours expensed or some other measure of progress. 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,


                                     F-144
<PAGE>   220

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 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.

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 and for the period from October 1, 1997 through January
30, 1998 were $192,000 and $105,000, respectively.

10.  FINANCIAL INSTRUMENTS:

    The Company's financial instruments consist of cash and cash equivalents,
accounts 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.


                                     F-147
<PAGE>   223

Insurance

    The Company carries a broad range of insurance coverage, including business
auto liability, general liability 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 and total sales to four major customers comprising
approximately 34%, 15%, 15% and 10% of sales during the period from October 1,
1997 through January 30, 1998.

    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, including cyclical changes in the aerospace industry.
However, management believes that its contract acceptance, billing and
collection policies are adequate to minimize the potential credit risk.

Mr. Mark Henderson, President
Mark Henderson, Inc.
Decatur, Georgia

We have audited the consolidated balance sheets of Mark Henderson, Inc., a
Georgia corporation, and Subsidiaries as of September 30, 1997 and February 28,
1997 and the related consolidated statements of income, retained earnings, and
cash flows for the years then ended. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the consolidated financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the consolidated financial statements.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Mark Henderson, Inc.
and Subsidiaries as of September 30, 1997 and February 28, 1997, and the results
of their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

change in reporting entity. The financial statements include the accounts of
Holland Electrical Systems, Inc. a 45%-owned subsidiary.

and year ended February 28, 1997; its 75%-owned subsidiary, Spectrol, Inc. for
the short year beginning May 1, 1997 and ending September 30, 1997 and six
months ended April 30, 1997; and its 45%-owned subsidiary, Holland Electrical
Systems, Inc for the seven months beginning March 1, 1997 and ending September
30, 1997 and year ending February 28, 1997. All material intercompany
transactions have been eliminated.

Effective March 1, 1997, Mark Henderson, Inc. and its 75%-owned subsidiary
Spectrol, Inc. have changed their fiscal year to end September 30 for both
financial and tax reporting purposes. Holland Electrical Systems, Inc. retained
its February 28 year end.

In June, 1998, the Company and its stockholders entered into a definitive
agreement with Integrate Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock was exchanged for cash and
shares of IES common stock. In addition, the key executives of the Company
entered into employment agreements with the Company and IES which have initial
term of two-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.

The interim financial statements for the nine months ended June 30, 1998 and
1997, and the year ended September 30, 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.

Revenue recognition

Mark Henderson, Inc. and Subsidiaries record revenue from contracts on the
percentage of completion method which recognizes revenue as work on a contract
progresses. The revenue recognized is that percentage of the estimated total
revenue that incurred costs to date bear to total estimated costs, after giving
effect to Company estimates of costs to complete based upon the most recent
information. Because of the inherent uncertainties in estimating costs, it is at
least reasonably possible that the estimates used will change within the near
future.

The application of this method results in "costs and estimated earnings in
excess of billings" (current asset) with respect to certain contracts and
"billings in excess of costs and estimated earnings" (current liability) with
respect to other contracts.

Cost of revenues earned includes all direct material, labor, and subcontract
costs and those indirect costs related to contract performance, such as indirect
labor, insurance, and depreciation.

The Company considers accounts receivable to be fully collectible; accordingly,
no allowance for doubtful amounts is required. If amounts become uncollectible,
they will be charged to operations when that determination is made.

Property and equipment

Property and equipment are stated at cost. Depreciation is computed using
accelerated and straight-line depreciation methods over estimated service lives
for financial reporting purposes. Principal service lives are:

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Property and equipment (continued)

Expenditures for major renewals and betterments which extend the useful lives of
property and equipment are capitalized. Expenditures for maintenance and repairs
are charged to expense as incurred.

Cash and cash equivalents

For purposes of the statements of cash flows, the Company considers all
investments purchased with a maturity of three months or less to be cash
equivalents.

Use of estimates

Generally accepted accounting principles require management to estimate some
amounts reported in the financial statements; actual amounts could differ.

Compensated absences

Employees are entitled to paid vacations depending on job classification, length
of service, and other factors. The amount of compensation for future absences
cannot be reasonably estimated, and, accordingly, no liability has been recorded
in the accompanying financial statements.

Income taxes

Mark Henderson, Inc., with the consent of its shareholders, has elected to be
taxed under the provisions of Subchapter S of the Internal Revenue Code
effective March 1, 1997. Under those provisions, the Company does not pay income
taxes on their proportionate share of the Company's taxable income.

Spectrol, Inc. and Holland Electrical Systems, Inc. are taxable corporations,
and the financial statements include a provision for taxes on their earnings and
losses.

Holland Electrical Systems, Inc. reports income on long-term contracts on the
basis of the "completed contract" method of accounting for income tax purposes
while the aforementioned "percentage of completion" method of accounting is used
for financial reporting. Under the "completed contract" method, billings and
costs are accumulated during the period of construction, but no profits are
recognized until completion and acceptance of the work. The current liability of
deferred income taxes results from the deferral of gross profit on uncompleted
contracts. Deferred income taxes are reduced by the alternative minimum tax that
will be allowed as a credit in future years.

Spectrol, Inc. and Holland Electrical Systems, Inc. also incur deferred income
taxes as a result of timing differences between the recognition of depreciation
for income tax reporting and financial reporting. Accelerated depreciation is
used for tax reporting, and straight-line depreciation is primarily used for
financial statement reporting.

The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109. (SFAS 109) is based on the assumption
that tax laws and financial accounting standards differ in their recognition and
measurement of assets, liabilities, equity, revenues, expenses, gains, and
losses. Therefore, differences arise between the amount of taxable income and
pretax financial income for a year, and the tax bases of assets or liabilities
differ from the amounts reported in financial statements. Since Holland
Electrical Systems, Inc. uses the completed contract method of accounting for
income tax purposes, the primary temporary differences between tax and financial
statements is the unrecognized profit on jobs in progress.

NOTE 10 - STOCK BONUS PLAN

Under certain circumstances, an officer of Holland Electrical Systems, Inc. has
the option to purchase shares of common stock of Holland Electrical Systems,
Inc. for amounts based upon the book value of the shares at the time of
exercise.

NOTE 11 - OFF-BALANCE-SHEET RISK AND CONCENTRATION OF CREDIT RISK

In March 1990, the Financial Accounting Standards issued Statement of Financial
Accounting Standards No. 105, Disclosure of Information about Financial
Instruments with Off-Balance-Sheet Risk and Financial Instruments with
Concentrations of Credit Risk. The pronouncement requires disclosure of
information about financial instruments for which risk could exceed amounts
reflected in the financial statements and information about significant
geographic, industry, or other concentrations of credit risk for all financial
instruments.

The Company has a potential concentration of credit risk in that it maintains
deposits with financial institutions in excess of amounts insured by FDIC.

Financial instruments which potentially expose the Company to concentrations of
credit risk consist primarily of trade accounts receivable. The Company has not
experienced significant losses related to receivables from individual customers
or groups of customers in a particular industry or geographic area. Due to these
factors, management believes no additional credit risk beyond amounts provided
for collection losses is inherent in the Company's accounts receivable.

                       DAVIS ELECTRICAL CONSTRUCTORS, INC.
                          NOTES TO FINANCIAL STATEMENTS
                          YEAR ENDED SEPTEMBER 31, 1997

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ACTIVITIES

         The Company is a national industrial electrical contractor. The Company
extends credit to its customers who are concentrated primarily in the
Southeastern region of the United States. The home office is located in
Greenville, South Carolina with branch offices in Midland, Michigan operating as
Davis Constructors Division and in Baton Rouge, Louisiana operating as Davis
International Division.

    In September, 1998, the Company and its stockholders entered into a
definitive agreement with Integrated Electrical Services, Inc. (IES), pursuant
to which all outstanding shares of Company's common stock was exchanged for cash
and shares of IES common stock. In addition, the key executives of the Company
entered into employment agreements with the Company and IES which have an
initial term of three to 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.

     INTERIM FINANCIAL INFORMATION
      The interim financial statements for the nine months ended June 30, 1998
      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.

     REVENUE AND COST RECOGNITION
      The Company reports contract revenues from firm-price and guaranteed
      maximum contracts on the percentage-of-completion method, measured by the
      percentage of costs incurred to date, to the total estimated costs for
      each contract. Revisions in contract revenues and cost estimates are
      reflected in the period in which the facts that require the revisions
      become known. Revenues from cost-plus-percentage and cost-plus-fixed fee
      contracts are reported as the costs are incurred. Provisions for estimated
      losses on uncompleted contracts are made in the period in which such
      losses become known.

      Contract costs include all direct material, labor and sub-contract costs
      and those indirect costs related to contract performance, such as indirect
      labor, equipment repairs, equipment rent, tools and supplies. General and
      administrative costs are charged to expense as incurred.

     PROPERTY AND EQUIPMENT
      Property and equipment, including permanent improvements to existing
      facilities, are carried at cost. Maintenance, repairs and other expenses
      not resulting in improvements are charged to expense as incurred.
      Depreciation is calculated using accelerated methods over the estimated
      useful lives of the respective assets.

     INCOME TAXES
      The Company, with the consent of its stockholders, has elected to be taxed
      as an S corporation effective October 1, 1995. Earnings and losses after
      that date are included in the personal income tax returns of the
      stockholders. Accordingly, the Company will not incur income tax
      obligations, and the financial statements will not include a provision for
      income taxes, except for provision of taxes in those states that do not
      recognize the S corporation election.

     CASH AND CASH EQUIVALENTS
      For purposes of reporting cash flows, the Company considers all liquid,
      nonequity investments with an original maturity of three months or less to
      be cash equivalents. The Company places its temporary cash investments
      with high credit quality financial institutions. At times such investments
      may be in excess of the FDIC insurance limits.

     ESTIMATES
      The financial statements include estimates and assumptions that affect the
      Company's financial position and results of operations and disclosure of
      contingent assets and liabilities. Actual results could differ from these
      estimates.

NOTE 5 - NOTE PAYABLE

         The Company has an unsecured $4,000,000 line of credit with a bank
which is partially guaranteed by the majority stockholder of the Company with
his guaranty limited to $2,000,000. The line bears interest at Libor plus 185
basis points and expires January 28, 1998. At September 30, 1997, $1,300,000 of
the line has been used under letters of credit which expire March 1, 1998 and
April 1, 1998, leaving $2,700,000 available for additional draws. At September
30, 1996, $1,250,000 of the line has been used under letters of credit which
expire March 1, 1997 and April 1, 1997, leaving $2,750,000 available for
additional draws. Letters of credit issued in connection with the lines of
credit are secured by the cash surrender value of life insurance on the life of
the majority stockholder of the Company. The provisions of the lines of credit
contain various covenants requiring the Company to maintain certain ratios and
to perform or not perform other actions. At September 30, 1997 and 1996, the
Company was in compliance with these provisions.

NOTE 7 - EMPLOYEE BENEFITS

         The Company provides deferred compensation to key employees under the
Davis Electrical Constructors, Inc. Incentive Plan. The plan provides for the
award of units to participants that are equivalent in value to one share of the
Company's stock at book value. Effective October 1, 1996, the Company elected to
suspend the Davis Electrical Constructors, Inc. Incentive Plan. The effect of
this election was to cease the appreciation in the book value of the unit as
compared to the initial value per unit defined by the plan on the date of award.
All other terms of the plan are still in effect. The present value of deferred
compensation under the plan since inception is computed as follows:

</TABLE>

         For the years ended September 30, 1997 and 1996, $203,550 and $188,047
was charged to operations under the Plan, respectively. The compensation
deferred under the plan is currently 60 percent vested to the participants.
Vesting under the plan begins after the fifth year of participation and
increases twenty percent per year until fully vested. Provisions for full
vesting of benefits under the plan are also provided upon the death or
disability of the participant, termination of the plan and certain other events
related to the majority stockholder.

NOTE 7 - EMPLOYEE BENEFITS, CONTINUED

         The participants shall receive payment of plan benefits upon
termination of employment or upon specific actions by the board of directors.
Upon termination of a participant's employment, the participant shall receive
payment of the value of his share units over such period of time (not to exceed
ten years) as the board shall determine in its absolute discretion.

         The Company also provides an executive bonus plan whereby the Company
shall pay bonuses for each fiscal year to each identified executive in an amount
equal to a specified percentage of Company's net profits for such fiscal year.

NOTE 8 - LEASE COMMITMENTS

         At September 30, 1997 and 1996, the Company was obligated under several
noncancellable operating leases on certain property and equipment that had an
initial or remaining term of more than one year. Lease payments charged to
operations under such leases were approximately $551,745 for the year ended
September 30, 1997 and $558,000 for the year ended September 30, 1996,
respectively. Future minimum lease payments under such operating leases that
have initial or non-cancelable terms in excess of one year are as follows:

NOTE 9 - INCOME TAXES, CONTINUED

         As discussed in Note 1, the Company has elected S corporation status
effective as of October 1, 1995. Accordingly, the deferred tax asset of $878,593
as of the date the election for the change was filed has been eliminated through
the deferred tax provision.

NOTE 10 - COMMITMENTS AND CONTINGENCIES

         The Company is self insured on major medical coverage which it provides
to its employees. Specific and aggregate excess reinsurance is carried by the
Company to limit potential costs under the self insured plan. Amounts due for
claims submitted by covered employees and the related charges to operations are
accounted for in the period the underlying occurrence or incident for the claim
occurs. Claims payable are processed by an administrator designated by the
Company.

NOTE 10 - COMMITMENTS AND CONTINGENCIES, CONTINUED

         The Company is insured for workers compensation claims in certain
states under policies with high deductible provisions generally totaling
$250,000 per incident. Specific and aggregate excess reinsurance is carried by
the Company to limit potential costs.

NOTE 11 - RELATED PARTY TRANSACTIONS

         The Company leases offices, warehouses and certain equipment from
stockholders and partnerships in which the stockholders are partners. For the
years ended September 30, 1997 and 1996, approximately $630,556 and $422,000 was
charged to operations under such operating leases, respectively.

NOTE 12 - MAJOR CUSTOMERS AND RISK CONCENTRATION

         The Company had sales of approximately 27.9 percent of total sales to
two major customers during 1997. In addition, the Company grants credit,
generally without collateral, to its customers, which are general contractors in
the industrial construction markets. Consequently, the Company is subject to
potential credit risk related to changes in business and economic factors within
the industrial construction markets. However, management believes that its
contract acceptance, billing and collection policies are adequate to minimize
the potential credit risk.

                          YEAR ENDED DECEMBER 31, 1997

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Business Activity

         The Company is a special trade contractor primarily engaged in
         nonresidential electrical work.

         Work is performed primarily under fixed-price contracts and unit-price
         contracts. Occasionally, cost-plus contracts are entered into.

         In May 1998, the Company and its stockholders entered into a definitive
         agreement with Integrate Electrical Services, Inc. (IES), pursuant to
         which all outstanding shares of the Company's common stock was
         exchanged for cash and shares of IES common stock. In addition, the key
         executives of the Company entered into employment agreements with the
         Company and IES which have 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.

         The interim financial statements for the three months ended March 31,
         1998 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.

         Use of Estimates

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and revenue and expenses during the
         period reported. Actual results could differ from those estimates.

         Revenue and Cost Recognition

         Contract revenues and costs on all significant long-term contracts are
         recognized using the percentage of completion method of accounting for
         each contract. The percentage of completion method recognizes


                                     F-176

                       FLORIDA INDUSTRIAL ELECTRICAL, INC.

                          NOTES TO FINANCIAL STATEMENTS

                          YEAR ENDED DECEMBER 31, 1997

                                 (IN THOUSANDS)



         revenue and cost as the work progresses. It takes into account the
         estimate of total contract revenue and cost expected to be realized at
         completion.

         Under the percentage of completion method, revenue is recognized based
         on the percentage that cost to date bears to total estimated cost,
         based on current estimates of cost to complete. No percentage of
         completion is recognized in the early stages of a contract (usually
         less than 5% complete) and any cost to date is not recognized.

         As contracts can extend over one or more years, revisions in estimates
         of cost and earnings during the course of the work are reflected in the
         accounting period in which the facts which require the revision become
         known. Provisions for estimated losses on uncompleted contracts are
         made in the period in which such losses are determined.

         Revenues from cost-plus contracts are recognized on the basis of costs
         incurred plus profit earned during the period.

         Contract revenue includes approved change orders, unpriced change
         orders initiated by the customer to the extent of cost incurred and
         known unit-price variances. Claims are recognized only when realization
         is probable and the amount can be reliably estimated.

         Contract cost includes all direct materials, labor, subcontract and
         other costs, and indirect costs identifiable with or allocable to the
         contract. Beginning August 1, 1996, the Company began allocating the
         cost of all owned equipment used for contracts directly to contract
         cost. Unallocated indirect and warranty costs are charged to expense as
         incurred and are included in cost of revenues earned. Unallocated
         material discounts earned are treated as a reduction of cost of
         revenues earned. General and administrative costs are charged to
         expense as incurred.

         The current assets, "Costs and estimated earnings in excess of billings
         on uncompleted contracts," represents revenues recognized in excess of
         amounts billed and costs incurred on contracts with no percentage of
         completion recognized. The current liability, "Billings in excess of
         costs and estimated earnings on uncompleted contracts," represents
         billings in excess of revenues recognized.

         Cash and Cash Equivalents

         The Company considers the following to be cash or cash equivalents: all
         cash on hand; demand

         deposits, savings accounts, money market accounts and certificates of
         deposit with financial institutions; brokerage houses' cash funds;
         mutual funds' cash funds; and other highly liquid debt instruments
         purchased with a maturity of three months or less.


Receivables

         Receivables are stated at net realizable value.

Property and Equipment

         Property and equipment are carried at cost less accumulated
         depreciation. Depreciation is computed by both the straight-line and
         accelerated methods over the estimated useful lives of the assets.

         Expenditures for maintenance and repairs are expense as incurred.
         Replacements and betterments which increase the value or materially
         extend the life of the related asset are capitalized. When assets are
         sold or retired, the cost and accumulated depreciation is removed from
         the accounts and any gain or loss is included in income.

Intangibles

         Intangibles are amortized on a straight-line basis over five years.

         Income Taxes

         The Company accounts for certain income and expense items differently
         for financial reporting and income tax purposes. Deferred income taxes
         reflect the estimated impact of these temporary timing differences by
         applying currently enacted tax laws. The nature of significant timing
         differences is described in the note entitled, "Income Taxes."

         Financial Instruments and Risk Concentration

         The Company is a minority business enterprise and operates throughout
         the southeastern United States, primarily in Florida.

                                 (IN THOUSANDS)


         Financial instruments which potentially subject the Company to
         concentrations of credit risk consist principally of cash and cash
         equivalents and contract receivables.

         The Company places cash and temporary cash investments with high
         quality financial institutions. At times, such investments may be in
         excess of the FDIC insurance limit.

         The Company provides credit, in the normal course of business, for
         construction contracts with both governmental and private entities.
         Significant contracts normally require payment and performance bonds.
         To reduce credit risk, the Company performs a credit evaluation before
         entering into a contract for which no bond is required.

         Historically, the Company has not incurred any significant credit
         related losses. In management's opinion, the Company's exposure to
         concentrations of credit risk is limited.

                       GALBRAITH ACQUISITION COMPANY, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                      FOR THE YEAR ENDED DECEMBER 31, 1997


NOTE 1:  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

GENERAL

Galbraith Acquisition Company, Inc. (the Corporation) was incorporated under the
laws of the state of Texas on September 17, 1994. The Corporation was formed as
a holding company for the purpose of acquiring its wholly owned subsidiary,
Galbraith Electric Company. Galbraith Electric Company, Inc. was founded in 1941
and is an electrical contractor whose principal activity is electrical
installation on new and existing commercial buildings. The work is performed
under fixed-price and modified fixed-price contracts. Most projects are located
in the central Texas area. The length of the contracts vary but are typically
less than one year.

In May, 1998, the Company and its stockholders entered into a definitive
agreement with Integrate Electrical Services, Inc. (IES), pursuant to which all
outstanding shares of the Company's common stock was exchanged for cash. In
addition, the key executives of the Company entered into employment agreements
with the Company and IES which 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.

The interim financial statements for the three months ended March 31, 1998 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.

Management uses estimates and assumptions in preparing these financial
statements in accordance with generally accepted accounting principles. Those
estimates and assumptions affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities, and the reported revenues
and expenses. Actual results could vary from the estimates that were used.

PRINCIPLES OF CONSOLIDATION

The  consolidated  financial  statements  include the accounts of  Galbraith
Acquisition  Company,  Inc. (a holding company) and its wholly owned
subsidiary.  Galbraith  Electric  Company,  Inc. is the  acquisition  company's
only subsidiary.  All significant intercompany transactions are eliminated in
the consolidation.

REVENUE AND COST RECOGNITION

Revenues from construction contracts are recognized on the
"percentage-of-completion" method, measured by the percentage of costs incurred
to date to the total estimated costs for each contract. That method is used
because management considers total cost to be the best available measure of
progress on the contracts. Because of inherent uncertainties in estimating
costs, it is at least reasonably possible that the estimates used will change
within the near term.


                                     F-192
<PAGE>   268
                       GALBRAITH ACQUISITION COMPANY, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                      FOR THE YEAR ENDED DECEMBER 31, 1997

Contract costs include all direct material, labor costs, and those other costs
related to contract performance such as indirect labor and insurance costs.
Selling, general, and administrative costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined. Changes in job performance, job conditions,
and estimated profitability may result in revisions to costs and income, which
are recognized in the period in which the revisions are determined. Changes in
estimated job profitability resulting from job performance, job conditions,
contract penalty provisions, claims, change orders, and settlements, are
accounted for as changes in estimates in the current period.

The asset, costs and estimated earnings in excess of billings on uncompleted
contracts, represents revenues recognized in excess of amounts billed. The
liability, billings in excess of costs and estimated earnings on uncompleted
contracts, represents billings in excess of revenues recognized.

INVENTORY

Inventory consists principally of materials and are valued at the lower of cost,
first-in, first-out method, or market.

PROPERTY AND EQUIPMENT

Property and equipment are stated at historical cost, net of accumulated
depreciation. Depreciation is computed using the straight-line method and
amounted to $59,178 and $60,408, including the depreciation for the excess cost
over net assets attributable to equipment, for the years ended December 31, 1997
and 1996, respectively. The excess of cost over net assets attributable to
equipment is being depreciated using the straight-line method over the estimated
remaining useful lives of the assets and amounted to $8,663 for each of the
years ended December 31, 1997 and 1996. Estimated lives used in calculating
depreciation are summarized by major asset category as follows:

- --------------------------------------------      ----------------------------
            Category                                       Useful Life

Building and improvements                                    31 to 40 years
Construction equipment                                        7 to 10 years
Vehicles                                                            5 years
Furniture and office equipment                                5 to 10 years


Maintenance, repairs, and minor replacements are charged to expense as incurred;
major replacements and betterments are capitalized. The cost of assets, which
are sold or retired, and the related accumulated depreciation are removed from
the accounts at the time of disposition, and any resulting gain or loss is
reflected in income for the period.

FEDERAL INCOME TAXES

Income taxes are provided for the tax effects of transactions reported in the
financial statements and consist of taxes currently due, plus deferred taxes
resulting from timing differences in the recognition of expense items for
financial accounting and tax purposes. The principal timing differences relate
to depreciation and bad debt 


                                     F-193

                       GALBRAITH ACQUISITION COMPANY, INC.

                      FOR THE YEAR ENDED DECEMBER 31, 1997

expense. The deferred taxes represent the future tax return consequences of
those differences, which will either be taxable or deductible when the assets
and liabilities are recovered or settled.

CASH EQUIVALENTS

For the purpose of the statements of cash flows, the Company considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of the Company's long-term debt approximates fair value
based on management's best estimate of interest rates that would be available to
the Company for similar debt obligations at December 31, 1997.

NOTE 2: CONTRACTS RECEIVABLE

                          NOTES TO FINANCIAL STATEMENTS



NATURE OF BUSINESS

    Arc Electric, Incorporated, a Virginia Corporation, is an electrical
    contractor headquartered in Chesapeake, Virginia. The Company specializes in
    hospital, industrial and office structures. The Company also installs
    industrial controls consisting of pneumatic, electrical and computer-based
    systems. The Company performs the majority of its contract work under fixed
    price contracts, with contract duration generally ranging from five to nine
    months. Arc Electric is a regional subcontractor operating from Richmond and
    southwestern Virginia through South Carolina.

    In September 1998, 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 were
    exchanged for cash and shares of IES common stock. In addition, the key
    executives of the Company have 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.

     The interim financial statements for the six months ended June 30, 1998 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ESTIMATES    The preparation of financial statements in conformity with
    generally accepted accounting principles requires management to make
    estimates and assumptions that affect the reported amounts of assets and
    liabilities and the reported amounts of revenues and expenses during the
    reporting period. Actual results could vary from the estimates that were
    used. Reference is made to the "Revenue Recognition" section below for
    discussion of significant estimates reflected in the Company's financial
    statements.

    REVENUE RECOGNITION     The Company recognizes revenue from long-term 
    contracts on the percentage-of-completion method, measured by the percentage
    of costs incurred to date compared to estimated total 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. Provisions for the total
    estimated losses, if any, on uncompleted contracts are made in the year 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 year 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 the 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 the 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued from preceding page)

    WARRANTY COSTS       For certain contracts, the Company warrants labor and
    materials for the first year after installation of new electrical systems.
    The Company charges warranty costs to operations in the year costs are
    incurred.

    CASH EQUIVALENTS     The Company considers all highly liquid debt 
    instruments purchased with an original maturity of three months or less to
    be cash equivalents.

    ACCOUNTS RECEIVABLE     The Company provides an allowance for doubtful 
    accounts receivable, based upon an analysis and aging of the accounts. The
    provision for uncollectible accounts charged to operations was $43,349 in
    1997.

    INVENTORY    Inventory is valued at the lower of cost or market, using the
    first-in, first-out method.

    PROPERTY AND EQUIPMENT      Depreciable assets are recorded at cost and
    depreciation and amortization are calculated 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 and amortization expense charged to operations was $118,100 in
    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
    the retirement or disposal of the property and equipment, the cost and
    related accumulated depreciation are removed from the accounts and any
    resulting gain or loss is recognized in the statement of income.

    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 and tax bases of assets and liabilities
    and are measured using enacted tax rates and laws.

PROPERTY AND EQUIPMENT

    Property and equipment, at cost, consists of the following (in thousands) as

JOINT VENTURE

    The Company formed a joint venture partnership with another electrical
    contractor to perform a large industrial contract. The partners are each
    responsible for performance of a specific phase of the contract. Each
    partner advanced $5,000 to fund the partnership, is responsible for funding
    its direct and indirect contract costs, and is responsible for maintaining
    job cost records for its portion of the job. The profit on the joint venture
    will be allocated based on job cost records. The Company's investment in the
    construction joint venture is accounted for by the pro rata combination
    method. At December 31, 1997, the financial statements include the following
    amounts related to Arc Electric, Incorporated's portion of the joint venture
    (in thousands):

FINANCIAL INSTRUMENTS

    The Company's financial instruments consist of cash and cash equivalents,
    accounts receivable, accounts payable, and short- and long-term debt. The
    Company believes that the carrying value of these instruments on the
    accompanying balance sheet approximates their fair value.

CONTINGENCIES

    Litigation

    The Company is involved in disputes and 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.

    In 1998, the Company is resolving disputed contract billings of $241,845
    through arbitration. At December 31, 1997, no revenue had been recognized
    for costs and estimated earnings on this disputed change order work.

    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.

MAJOR CUSTOMERS AND RISK CONCENTRATION

    The Company had sales of approximately 25 percent of total sales to two
    major customers during the year ended December 31, 1997.

    The Company routinely maintains cash balances in financial institutions in
    excess of federally insured limits.

    In addition, the Company grants credit, generally without collateral, to its
    customers, which are primarily general contractors located from Richmond and
    southwestern Virginia through South Carolina. Consequentially, the Company
    is subject to potential credit risk related to changes in business and
    economic factors within those areas. However, management believes that its
    contract acceptance, billing and collection policies are adequate to
    minimize the potential credit risk.

                         BRINK ELECTRIC CONSTRUCTION CO.

                          NOTES TO FINANCIAL STATEMENTS
                             MARCH 31, 1998 AND 1997



(1)  NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

a.   NATURE OF BUSINESS AND ORGANIZATION

Brink Electric Construction Co. (the Company) is engaged in the construction of
electric power transmission lines and substations in the western United States.
During the year ended March 31, 1998, the transmission and substation divisions
accounted for 28 percent and 72 percent of total revenues and 41 percent and 59
percent of gross profit, respectively. Work is generally performed under
unit-price contracts. The length of the majority of the contracts is less than
two years.

In August, 1998, 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 was exchanged for cash and
shares of IES common stock. In addition, the key executives of the Company
entered into employment agreements with the Company and IES which have initial
terms 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.

b.   SIGNIFICANT ACCOUNTING POLICIES

The interim financial statements for the three months ended June 30, 1998 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.

1.   Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

2.   Revenue and Cost Recognition

Revenues from construction contracts are recognized on the
percentage-of-completion method, measured by the percentage of costs to date to
estimated costs to complete for each contract. This method is used because
management considers costs incurred to be the best available measure of progress
on these contracts. Revenue from cost-plus-fee contracts is recognized on the
basis of costs incurred during the period plus the fee earned. Due to
uncertainties inherent in the estimation process, it is at least reasonably
possible that the completion costs for contracts in progress at March 31, 1998,
will be revised significantly in the near term.

Contract costs include all direct material, direct labor, and subcontract costs
and those indirect costs related to contract performance, such as labor,
supplies, tools, repairs, and depreciation costs. The costs of uninstalled
materials specifically produced or fabricated for a project and delivered to a
job site are included in the contract costs used to measure the extent of
progress. General and administrative costs are charged to expense as incurred.
Provisions for estimated costs are charged to expense as incurred. Provisions
for estimated losses on uncompleted contracts are made in the period in which
such losses are determined. Changes in job performance, job conditions, and
estimated profitability, including those arising from contract penalty
provisions and final contract settlements, may result in revisions to costs and
income and are recognized in the period in which the revisions are determined.

The asset, "Costs and Estimated Earnings in Excess of Billings on Uncompleted
Contracts," represents revenues recognized in excess of amounts billed. The
liability, "Billings in Excess of Costs and Estimated Earnings on Uncompleted
Contracts," represents billings in excess of revenues recognized.

3.   Property and Equipment

Equipment and leasehold improvements are stated at cost. Depreciation expense is
computed principally by the straight-line method based on the following
estimated useful lives:

includes contract receivables relating to the Company's billings to the joint
venture. The Company's share of the gross joint venture revenue, cost of revenue
and operating income is included in the statement of income.

                          NOTES TO FINANCIAL STATEMENTS
                             MARCH 31, 1998 AND 1997


(4)  STOCKHOLDERS' NOTES RECEIVABLE

Stockholder notes receivable represent Company financing of employee purchases
of Company stock. The notes bear interest at prime rate adjusted quarterly and
are due in August 1998. No principal or interest payments are required until
maturity. The notes are secured by the stock purchased.

(5)  SHORT-TERM BANK BORROWINGS/REVOLVING LINE OF CREDIT

At March 31, 1998 and 1997, the Company had available a revolving line of credit
with First Bank of South Dakota. Under the credit agreement, the available line
is the lesser of $2.5 million or a calculated asset borrowing base. There were
no amounts outstanding at March 31, 1998 and 1997. Interest is payable monthly
at the high Wall Street Journal Prime Rate, and the note is secured by
receivables and equipment. The credit agreement contains certain covenants, the
most restrictive of which include a requirement to maintain a minimum book
tangible net worth of $5,000,000 and a maximum debt-to-tangible net worth ratio
not to exceed 1.5 to 1.0. The line of credit matures August 1998.

(6)  NOTE PAYABLE

During the year ended March 31, 1997, the Company purchased 63,712 shares of its
common stock for $1,028,216. The stock purchase agreement requires the Company
to pay $400,000 in cash with the remaining $628,216 being financed over five
years. The agreement requires annual principal payments of $125,643 plus annual
interest payments at the rate of 2 percent below prime rate. The shares
purchased by the Company are held in escrow until satisfaction of the stock
purchase agreement and, accordingly, have been classified as treasury stock in
the accompanying financial statements. Interest expense under this note totaled
$58,033 and $9,816 during the years ended March 31, 1998 and 1997, respectively.

(7)  LEASE ARRANGEMENTS

The Company leases property and equipment used in its operations under various
agreements which are substantially month-to-month operating leases. The total
rental expense included in the statements of income for the years ended March
31, 1998 and 1997, was $571,100 and $535,306, respectively. Included in these
amounts are payments to a partnership affiliated with the Company through common
ownership:

                             MARCH 31, 1998 AND 1997


The effective rate differs from the federal statutory rate of 34 percent
primarily due to state taxes and certain nondeductible expenses for tax
purposes.

Deferred income taxes are provided on temporary differences between financial
statement and taxable income. At March 31, 1998, there are temporary differences
that relate principally to the use of accelerated depreciation for tax, the
deferral of taxable income on contracts less than 10 percent complete, joint
venture contracts, and accrued stockholder bonuses. Deferred tax assets total
$120,000 and $111,000 at March 31, 1998 and 1997, respectively, while deferred
tax liabilities total $199,430 and $64,000 at March 31, 1998 and 1997,
respectively.

                          NOTES TO FINANCIAL STATEMENTS
                             MARCH 31, 1998 AND 1997


(12) MAJOR CUSTOMERS AND RISK CONCENTRATION:

The Company had sales of approximately 25 percent of total sales to two major
customers during 1997.

In addition, the Company grants credit, generally without collateral, to its
customers, which are general contractors in the transmission line and substation
markets in the United States. 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.

                          Independent Auditor's Report


       Board of Directors
       Goss Electric Company, Inc.
       Decatur, Alabama

       We have audited the accompanying balance sheet of Goss Electric Company,
       Inc. as of December 31, 1997 and the related statements of income and
       retained earnings, and cash flows for the year 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 audit.

       We conducted our audit 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 audit
       provides 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 Goss Electric
       Company, Inc. at December 31, 1997, and the results of its operations and
       its cash flows for the year then ended in conformity with generally
       accepted accounting principles.

       The 1997 financial statements were reviewed by us, and our report
       thereon, dated April 1, 1998, stated that we were not aware of any
       material modifications that should be made to those statements for them
       to be in conformity with generally accepted accounting principles.
       However, a review is substantially less in scope than an audit and does
       not provide a basis for the expression of an opinion on the financial
       statements taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS
                           GOSS ELECTRIC COMPANY, INC.
                                December 31, 1997


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

A.   Company's activities and operating cycle - The Company is engaged in a
     single industry: the construction of industrial electric systems. The work
     is performed under cost-plus-fee contracts, fixed-price contracts, and
     fixed-price contracts modified by incentive and penalty provisions.
     Construction projects are located in the southeastern part of the United
     States.

     In September, 1998, the Company and its stockholders entered into a
     definitive agreement with Integrate Electrical Services, Inc. (IES),
     pursuant to which all outstanding shares of the Company's common stock was
     exchanged for cash and shares of IES common stock. In addition, the key
     executives of the Company entered into employment agreements with the
     Company and IES which have 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.

     The interim financial statements for the six months ended June 30, 1998 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.

B.   Revenues from cost-plus-fee contracts are recognized on the basis of costs
     incurred during the period plus the fee earned. Revenues from fixed-price
     and modified fixed-price construction contracts are recognized on the
     percentage-of-completion method, measured by the percentage of costs
     incurred to date to estimated total costs for each contract. This method is
     used because management considers expended costs to be the best available
     measure of progress on these contracts. Because of the inherent
     uncertainties in estimating costs, it is at least reasonably possible that
     the estimates used will change within the near term.

     The current asset, "Costs and estimated earnings in excess of billings on
     uncompleted contracts," represents revenue 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
     revenue recognized.

     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. Selling, general, and
     administrative costs are charged to expense as incurred. Provisions for
     estimated losses on uncompleted contracts are made in the period in which
     such losses are determined. Changes in job performance, job conditions, and
     estimated profitability, including those arising from contract penalty
     provisions, and final contract settlements may result in revisions to costs
     and income and are recognized in the period in which the revisions are
     determined. Profit incentives are included in revenues when their
     realization is reasonably assured. 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 the
     balance sheet date will be collected within the subsequent fiscal year.

                               December 31, 1997

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

C.   Property and equipment - Property and equipment is valued at cost less
     accumulated depreciation. Expenditures for maintenance, repairs and
     renewals of relatively minor items are charged to income as incurred.
     Depreciation and amortization are provided principally on the straight-line
     method over the estimated useful lives of related assets. Assets are
     generally depreciated over periods ranging from 3 to 10 years. For income
     tax purposes, accelerated methods of depreciation are generally used.

D.   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,
     determined by the first-in-first-out (FIFO) method.

E.   Allowance for doubtful accounts - The Company's receivables are deemed  
     collectible.  No allowance for doubtful accounts is provided.

F.   Investments - Investments in securities are classified as securities 
     available for sale.

G.   Cash and Cash Equivalents - The Company considers cash on hand and in
     demand deposits, as well as those investments which are generally part of
     its short-term management activities, to be cash and cash equivalents.

H.   Income Taxes - The Company, with the consent of its stockholders, has
     elected under the Internal Revenue Code and the Code of Alabama to be an S
     Corporation. In lieu of corporate income taxes, the stockholders of an S
     Corporation are taxed on their proportionate share of the Company's taxable
     income. Therefore, no provision or liability for income taxes has been
     included in the financial statements.

I.   Use of Estimates - The process of preparing financial statements in
     conformity with generally accepted accounting principles requires the use
     of estimates and assumptions regarding certain types of assets,
     liabilities, revenues, and expenses. Such estimates primarily relate to
     unsettled transactions and events as of the date of the financial
     statements. Accordingly, upon settlement, actual results may differ from
     estimated amounts.

J.   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." Adoption of this standard did not have a
     material effect on the financial position or results of operations of the
     Company.

                        MID-STATES ELECTRIC COMPANY, INC.
                      NOTES TO AUDITED FINANCIAL STATEMENTS
                          YEAR ENDED DECEMBER 31, 1997



NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

(1)      BUSINESS ACTIVITY. The Company is engaged as a licensed electrical
         contractor in several states and is based in Jackson, Tennessee. The
         work is performed under fixed-price contracts and fixed-price contracts
         modified by incentive provisions. The Company also manages, for a fee,
         construction projects of others.

         In July, 1998, the Company and its stockholders entered into a
         definitive agreement with Integrate Electrical Services, Inc. (IES),
         pursuant to which all outstanding shares of the Company's common stock
         was exchanged for cash and shares of IES common stock. In addition, the
         key executive of the Company entered into employment agreements with
         the Company and IES which have initial term of three 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.

         The interim financial statements for the six months ended June 30, 1998
         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.


         REVENUE AND COST RECOGNITION. Revenue from fixed-price and modified
         fixed-price construction contracts are recognized on the
         percentage-of-completion method, measured by the percentage of cost
         incurred to date to estimated total cost for each contract. Management
         considers total cost to be the best available measure of progress on
         the contracts.

         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. Selling, general, and
         administrative costs are charged to expense as incurred. Provisions for
         estimated losses on uncompleted contracts are made in the period in
         which such losses are determined. Changes in job performance, job
         conditions, and estimated profitability may result in revisions to
         costs and income and are recognized in the period in which the
         revisions are determined.

         The asset, "Costs and estimated earnings in excess of billings on
         uncompleted contracts", represents revenues recognized in excess of
         amounts billed. The liability, "Billings in excess of costs and
         estimated earnings on uncompleted contracts", represents billings in
         excess of revenues recognized.

(2)      INVENTORIES. Various electrical supplies are stated at cost using the
         first in, first out method or market value, whichever is less.

                        MID-STATES ELECTRIC COMPANY, INC.
                      NOTES TO AUDITED FINANCIAL STATEMENTS
                          YEAR ENDED DECEMBER 31, 1997


(3)      PROPERTY, PLANT AND EQUIPMENT. Properties and equipment are recorded at
         acquisition cost. Depreciation and amortization are computed based on
         the estimated useful lives of the individual assets and/or the life of
         the leases, respectively. Accelerated depreciation methods are used to
         depreciate certain equipment and automotive equipment. All building
         assets are depreciated or amortized using the straight-line method.
         Expenditures for maintenance and repairs are charged to expense as
         incurred.

(4)      INCOME TAXES. The Corporation's stockholders have elected "S"
         corporation status. No provision has been made for federal taxes since
         such taxes represent the personal liability of the individual
         stockholders.

         State income taxes have been provided for all items included in the
         statement of income, regardless of the period reflected for state
         income tax purposes. The Company uses the percentage of completion
         method to recognize contract income for both financial statement and
         tax purposes. Prior to the year ended December 31,1993, the company
         used the completed contracts method of income recognition for income
         tax reporting.

         Under Internal Revenue Code Section 481 the Company was allowed to
         recognize revenues and costs previously deferred over a four year
         period ending December 31, 1996. For financial statement purposes, the
         accrued salary to a more than five-percent stockholder is deducted as
         an expense but it cannot be claimed for tax purposes until the amount
         is actually paid in the subsequent year. Deferred taxes are reflected
         for timing differences which are composed of contract revenues and
         costs previously deferred for tax reporting and the recording of
         accrued salary to a more than five-percent stockholder.

(5)      CASH AND CASH EQUIVALENTS. Cash and cash equivalents include all cash
         accounts and temporary investments with an original maturity of three
         months or less.

(6)      USE OF ACCOUNTING ESTIMATES. The preparation of financial statements in
         conformity with generally accepted accounting principles requires
         management to make estimates and assumptions that affect the reported
         amounts of certain assets and liabilities and disclosures. Accordingly,
         the actual amounts could differ from those estimates. Any adjustments
         applied to estimated amounts are recognized in the year in which such
         adjustments are determined.

financial institution that exceeded regulatory insurance by approximately
$36,611. If the financial institution failed to completely perform under the
terms of the financial instruments, the exposure for credit loss would be the
amount on deposit in excess of regulatory insurance.

At December 31, 1997, the Company maintained approximately $39,000 in overnight
purchase of securities with the intention of resale with First Tennessee Bank.
These funds are used to purchase a Federal Home Loan Mortgage Corporation REMIC
on an overnight basis. The market value of this security was approximately
$40,000 as of December 31, 1997. In the event First Tennessee failed to
completely perform under the terms of the agreement, the Company's exposure to
credit loss would be offset by the value of the underlying security.

NOTE H - CONCENTRATION OF RISK (CONTINUED):

At December 31, 1997, the Company maintained approximately $247,000 in overnight
purchase of securities with intent to resale with First Bank. These funds are
used to purchase a Federal National Mortgage Association bond on an overnight
basis. The market value of this security is approximately $995,000 as of
December 31, 1997. In the event First Bank failed to completely perform under
the terms of the agreement, the Company's exposure to loss would be offset by
the value of the underlying security.

NOTE L - MAJOR CUSTOMERS AND RISK CONCENTRATION:

The Company had sales of approximately 75 percent of total sales to four major
customers during 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 the continental United States. 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.

                          T & H ELECTRICAL CORPORATION

                          NOTES TO FINANCIAL STATEMENTS

================================================================================
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Company's Activities and Operating Cycle

         The Company is engaged in the business of electrical construction
         contracting. The length of the Company's contracts varies but typically
         extends less than two years. The Company has therefore used the
         operating cycle concept in classifying all contract-related assets and
         liabilities as current on the balance sheet.

         In September, 1998, the Company and its stockholders entered into a
         definitive agreement with Integrate Electrical Services, Inc. (IES),
         pursuant to which all outstanding shares of the Company's common stock
         was exchanged for cash and shares of IES common stock. In addition, the
         key executives of the Company entered into employment agreements with
         the Company and IES which have 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.

         The interim financial statements for the nine months ended June 30,
         1998 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.

    Revenue and Cost Recognition

         Revenues from construction contracts through September 30, 1996 have
         been recognized on the percentage of completion method for financial
         accounting purposes and on the completed contract method for tax
         purposes. To qualify for the completed contract method for tax purposes
         the Company's gross revenues must not exceed $10 million for the
         preceding three years. For the three year period ending September 30,
         1996 the Company's average yearly gross revenues exceeded this
         threshold. Therefore, all contracts entered into after September 30,
         1996 are being accounted for using the percentage of completion method
         for both tax purposes and for financial accounting purposes.

         The percentage of completion method is computed using the cost to cost
         method. 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. General and
         administrative costs are charged to expense as incurred. Provisions for
         estimated losses on uncompleted contracts are made in the period in
         which such losses are determined. The asset, "Costs and estimated
         earnings in excess of billings on uncompleted contracts" represents
         revenues recognized in excess of amounts billed. The liability,
         "Billings in excess of costs and estimated earnings on uncompleted
         contracts" represents billings in excess of revenues recognized.

         The Company has several "Time-and-Materials" fee type jobs in process
         at September 30, l997 and 1996. Management refers to these jobs as
         "Open Ended Cost Plus Contracts", since these jobs do not have a fixed
         contract price as with Fixed Price Contracts. The total contract amount
         is determined by the amount of work ultimately performed. The amount
         under total contract price in the schedule of Contracts In Progress for
         these contracts is management's best estimate of the total that will be
         billed on these jobs.

    Property and Equipment

         Depreciation on such assets is being computed for both financial
         accounting reporting purposes and income tax reporting purposes under
         the modified accelerated cost recovery system. For the years ended
         September 30, l997 and l996, depreciation under this method totaled
         $287,297 and $290,187, respectively.

    Inventory Valuation

         Inventories are valued at the lower of cost (first-in, first-out) or
         market prices.

    Use of Estimates

         The preparation of financial statements in conformity with the income
         tax basis of accounting requires management to make estimates and
         assumptions that affect certain reported amounts and disclosures.
         Accordingly, actual results could differ from those estimates.

    Concentration of Credit Risk

         At year end, the Company had on deposit with a bank an amount in excess
         of FDIC insurance limits. The Company has not experienced any losses in
         such account and believes it is not exposed to any significant credit
         risk to cash.

    Deferred Income Taxes

         Deferred income taxes are provided for differences in timing in
         reporting income for financial statement and tax purposes arising from
         differences in the methods of accounting for construction contracts.
         For the year ended September 30, 1997, the Company had earnings before
         income taxes of $1,214,383 for income tax purposes and $637,340 for
         financial statement reporting purposes. Income tax expense for the year
         ended September 30, 1997 totaled $251,922 with $375,635 currently
         payable and a decrease in deferred of $123,713. A credit for prior year
         alternative minimum tax of $129,862 was available and used during the
         year ended September 30, 1997. For the year ended September 30, 1996,
         the Company had earnings before income taxes of $90,892 for income tax
         purposes and $258,042 for financial statement reporting purposes.
         Income tax expense for the year ended September 30, 1996 totaled
         $100,419 with $67,127 currently payable and $33,292 deferred.
         Alternative minimum tax for the year ended September 30, 1996 totaled
         $47,378.

DESCRIPTION OF LEASING ARRANGEMENTS

     The Company leased a vehicle under an operating lease which required
     monthly lease payments of $800.00 and expired June 30, 1997.

CONCENTRATION:

     The Company grants credit, generally without collateral, to its customers,
which are general contractors in the commercial and industrial construction
markets in North Carolina. 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.

     This Prospectus, as appropriately amended or supplemented, may be used from
time to time principally by persons (the "Selling Stockholders") who have
received shares of common stock, par value $0.01 per share (the "Common Stock"),
of Integrated Electrical Services, Inc. (the "Company") in connection with the
acquisition by the Company of securities or assets held by such persons, or
their transferees, and who wish to offer and sell such shares of Common Stock in
transactions in which they and any broker-dealer through whom such shares are
sold may be deemed to be Underwriters within the meaning of the Securities Act
of 1933, as amended (the "Securities Act"), as more fully described herein. The
Company will receive none of the proceeds from any such sale. Any commissions
paid or concessions allowed to any broker-dealer, and, if any broker-dealer
purchases such shares as principal, any profits received on the resale of such
shares, may be deemed to be underwriting discounts and commissions under the
Securities Act. Printing, certain legal and accounting, filing and other similar
expenses of this offering will be paid by the Company. The Selling Stockholders
will generally bear all other expenses of this offering, including brokerage
fees and any underwriting discounts or commissions.

to the offer and issuance by the Company from time to time of 21,000,000 shares
of Common Stock in connection with its acquisition of the securities and assets
of other businesses.

offered hereby on the NYSE. The last reported sale price of the Common Stock on
the NYSE on September 11, 1998 was $13 7/8 per share.

                              PLAN OF DISTRIBUTION
 
     This Prospectus, as appropriately amended or supplemented, may be used from
time to time principally by persons who have received shares of Common Stock in
connection with acquisitions by the Company of securities and assets held by
such persons, or their transferees, and who wish to offer and sell such shares
of Common Stock (such persons are herein referred to as "Selling Stockholders")
in transactions in which they and any broker-dealer through whom such shares are
sold may be deemed to be Underwriters within the meaning of the Securities Act.
The Company will receive none of the proceeds from any such sales. There
presently are no arrangements or understandings, formal or informal, pertaining
to the distribution of the shares of Common Stock described herein. Upon the
Company being notified by a Selling Stockholder that any material arrangement
has been entered into with a broker-dealer for the sale of shares of Common
Stock bought through a block trade, special offering, exchange distribution or
secondary distribution, a supplemented Prospectus will be filed, pursuant to
Rule 424(b) under the Securities Act, setting forth (i) the name of each Selling
Stockholder and the participating broker-dealer(s), (ii) the number of shares
involved, (iii) the price at which the shares were sold, (iv) the commissions
paid or the discounts allowed to such broker-dealer(s), where applicable, (v)
that such broker-dealer(s) did not conduct any investigation to verify the
information set out in this Prospectus and (vi) other facts material to the
transaction.
 
     Selling Stockholders may sell the shares being offered hereby from time to
time in transactions (which may involve crosses and block transactions) on the
NYSE, in negotiated transactions or otherwise, at market prices prevailing at
the time of the sale or at negotiated prices. Selling Stockholders may sell some
or all of the shares in transactions involving broker-dealers, who may act
solely as agent and/or may acquire shares as principal. Broker-dealers
participating in such transactions as agent may receive commissions from Selling
Stockholders (and, if they act as agent for the purchaser of such shares, from
such purchaser), such commissions computed in appropriate cases in accordance
with the applicable rules of the NYSE, which commissions may be at negotiated
rates where permissible under such rules. Participating broker-dealers may agree
with Selling Stockholders to sell a specified number of shares at a stipulated
price per share and, to the extent such broker-dealer is unable to do so acting
as an agent for the Selling Stockholder, to purchase as principal any unsold
shares at the price required to fulfill the broker-dealer's commitment to
Selling Stockholders. In addition or alternatively, shares may be sold by
Selling Stockholders and/or by or through other broker-dealers in special
offerings, exchange distributions or secondary distributions pursuant to and in
compliance with the governing rules of the NYSE, and in connection therewith
commissions in excess of the customary commission prescribed by such governing
rules may be paid to participating broker-dealers, or, in the case of certain
secondary distributions, a discount or concession from the offering price may be
allowed to participating broker-dealers in excess of the customary commission.
Broker-dealers who acquire shares as principal may thereafter resell such shares
from time to time in transactions (which may involve crosses and block
transactions and which may involve sales to or through other broker-dealers,
including transactions of the nature described in the preceding two sentences)
on the NYSE, in negotiated transactions or otherwise, at market prices
prevailing at the time of sale or at negotiated prices, and in connection with
such resales may pay to or receive commissions from the purchaser of such
shares.
 
     The Company may agree to indemnify each Selling Stockholder as an
Underwriter under the Securities Act against certain liabilities, including
liabilities arising under the Securities Act. Each Selling Stockholder may
indemnify any broker-dealer that participates in transactions involving sales of
the shares against certain liabilities, including liabilities arising under the
Securities Act.
 
     The Selling Stockholders may resell the shares offered hereby only if such
securities are qualified for sale under applicable state securities or "blue
sky" laws or exemptions from such registration and qualification requirements
are available.

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
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 has entered into indemnification agreements with each of its 
executive officers and directors.

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) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
 
                                      II-5
<PAGE>   343
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
          (4) 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 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.

                          AGREEMENT AND PLAN OF MERGER

          AGREEMENT AND PLAN OF MERGER ("Agreement") dated as of September 11,
1998 among Integrated Electrical Services, Inc., a Delaware corporation ("IES"),
Davis Acquisition Corporation, a South Carolina corporation and a wholly owned
subsidiary of IES ("Acquisition"), Davis Electrical Constructors, Inc., a South
Carolina corporation ("Company"), and James B. Stephens, J. Michael Stephens,
William N. Byrd, James C. Henderson, J. Lowell Hughes and William M. Sumerel,
who are all of the stockholders of the Company (together, the "Company
Stockholders").

                                    RECITALS:

          WHEREAS, the Boards of Directors of IES and the Company have
determined that the combination of IES and the Company is in the best interests
of the stockholders of IES and the Company, respectively;

          WHEREAS, the Company Stockholders desire to sell to IES all of the
issued and outstanding shares of capital stock of the Company, free and clear of
all Liens (as defined in Section 10.16), and the Company Stockholders agree to
be bound by a covenant not to compete; and

          WHEREAS, IES desires to acquire such shares of capital stock of the
Company as more fully set forth herein and enforce the covenant not to compete.

          NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth herein, the parties hereto agree as follows:

                                    ARTICLE I

                                   THE MERGER

     SECTION 1.1. THE MERGER. (a) At the closing of the transactions
contemplated by this Agreement (the "Closing") and upon delivery of the
documents listed in Section 1.6, at the Effective Time (as hereinafter defined),
Acquisition shall be merged (the "Merger") with and into the Company in
accordance with the South Carolina Business Corporation Act, as amended ("South
Carolina Law"), whereupon the separate existence of Acquisition shall cease, and
the Company shall be the surviving corporation (the " Surviving Corporation").

          (b) Immediately following the delivery of the documents listed in
Section 1.6, the Company and Acquisition will file Articles of Merger (the
"Certificate of Merger") with the South Carolina Secretary of State and make all
other filings or recordings required by South Carolina Law in connection with
the Merger. The Merger shall become effective at such time (the "Effective
Time") as the Certificate of Merger is duly filed with the South Carolina


<PAGE>   7

Secretary of State (or at such later time as may be agreed in writing by the
parties hereto and specified in the Certificate of Merger).

          (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, assets, powers, privileges, and franchises and be
subject to all of the obligations, liabilities, restrictions, and disabilities
of the Company and Acquisition, all as provided under South Carolina Law.

          (d) The Closing of the transactions shall take place at the offices of
Merline & Thomas, P.A. in Greenville, South Carolina, at 10:00 a.m. eastern
standard time, on the first business day following the date first written above
in this Agreement.

     SECTION 1.2. CONVERSION OF SHARES.  At the Effective Time:

                    (a) (i) the shares of common stock, $1.00 par value, of the
     Company ("Company Common Stock") outstanding immediately prior to the
     Effective Time shall be converted into the right to receive, without
     interest, an aggregate of 214,046 shares of common stock, $0.01 par value,
     of IES ("IES Common Stock"), as equitably adjusted to give effect to any
     stock split, stock dividend or stock combination or reclassification of
     such shares occurring during the period from the date hereof to the
     Closing, and (ii) IES shall pay cash consideration equal to $49,814,605.00
     less the amount of deferred compensation paid to Company Stockholders
     pursuant to Section 5.16, by wire transfer of immediately available funds
     to the accounts designated by Company (collectively, the "Merger
     Consideration"); and

                    (b) each share of common stock of Acquisition outstanding
     immediately prior to the Effective Time shall be converted into and become
     one share of common stock of the Surviving Corporation with the same
     rights, powers, and privileges as the shares so converted and shall
     constitute the only outstanding shares of capital stock of the Surviving
     Corporation.

     SECTION 1.3. SURRENDER AND PAYMENT. At the Effective Time, the Company
Stockholders will deliver to IES the certificates listed on Schedule 3.2(a) (the
"Certificates") representing all of the outstanding shares of Company Common
Stock, and IES will deliver, in exchange therefor, the Merger Consideration
divided among the Company Stockholders in accordance with the written
instructions provided in Schedule 3.2(a). The Certificates will be duly endorsed
(or accompanied by duly execute powers), with signatures of those Company
Stockholders not present at the Closing guaranteed by a commercial bank or by a
member firm of the New York Stock Exchange (the "NYSE") for any Company
Stockholder that is not present at the Closing of the Merger.

     SECTION 1.4. WITHHOLDING RIGHTS. Each of the Surviving Corporation and IES
shall be entitled to deduct and withhold from the consideration otherwise
payable to any Person (as defined in Section 10.16) pursuant to this Article I
such amounts as it is required to deduct and withhold with respect to the making
of such payment under any provision of federal, state, local, 



                                     - 2 -
<PAGE>   8

or foreign tax law. To the extent that amounts are so withheld by the Surviving
Corporation or IES, as the case may be, such withheld amounts shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Company Common Stock in respect of which such deduction and
withholding was made by the Surviving Corporation or IES, as the case may be, so
long as the Surviving Corporation or IES actually pays over such withheld
amounts to the proper authority.

     SECTION 1.5. LOST CERTIFICATES. If any Certificate shall have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen, or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, IES will
issue in exchange for such lost, stolen, or destroyed Certificate the Merger
Consideration to be paid in respect of the shares of Company Common Stock
represented by such Certificates as contemplated by this Article I.

     SECTION 1.6. OTHER DOCUMENTS TO BE DELIVERED IMMEDIATELY PRIOR TO THE
EFFECTIVE TIME.

          (a) At the Closing and immediately prior to the Effective Time, the
Company and the Company Stockholders will deliver to IES:

          The Company Stockholders jointly and severally represent and warrant
to IES as follows upon execution of this Agreement and as of the Effective Time:

     SECTION 3.1. ORGANIZATION AND QUALIFICATION. The Company, and each of its
subsidiaries, if any, are listed on Schedule 3.1 (the "Subsidiaries"), and each
is a corporation duly organized, validly existing, and in good standing under
the laws of the state of its incorporation and has the requisite corporate power
to carry on its business as it is now being conducted. The Company, and each of
the Subsidiaries, is duly qualified to conduct business as a foreign corporation
in every state of the United States in which its ownership or lease of property
or the conduct of its business and operations makes such qualification
necessary, except for such states in which the Company's or the Subsidiaries'
failure to be so qualified is not reasonably expected to have, individually or
in the aggregate, a Company Material Adverse Effect (as defined in Section
10.16). Schedule 3.1 contains a list of all jurisdictions in which the Company
and each of the Subsidiaries is authorized or qualified to do business. The
Company has heretofore delivered to IES true and complete copies of the articles
of incorporation and bylaws of the 




                                     - 6 -

thereto, as currently in effect.

     SECTION 3.2. CAPITALIZATION; OWNERSHIP. (a) The authorized capital stock of
the Company consists of 500,000 shares of Company Common Stock, of which 62,500
shares are issued and outstanding (the "Company Shares"). The Company Shares are
all of the issued and outstanding shares of capital stock of the Company and
have been duly authorized and validly issued and are fully paid and
nonassessable and free of preemptive rights. There are not, as of the date
hereof, any outstanding or authorized subscriptions, options, warrants, calls,
rights, commitments, or any other agreements of any character (any of the
foregoing, a "Commitment") obligating the Company to issue any additional shares
of capital stock of the Company, or any other securities convertible into or
evidencing the right to subscribe for any shares of capital stock of the
Company. The Company Stockholders own the respective number of shares of Company
Common Stock set forth on Schedule 3.2(a) attached hereto, free and clear of all
Liens other than restrictions imposed by applicable securities laws. Each of the
Company Stockholders has full legal right, power and authority to exchange,
assign and transfer or cause to be exchanged, assigned or transferred their
respective shares of Company Common Stock. The delivery to IES of the Company
Shares pursuant to the terms of this Agreement will transfer valid title
thereto, free and clear of all Liens other than restrictions imposed by
applicable securities laws. No Company Stockholder has or will have appraisal or
similar rights as a result of the consummation of the transactions contemplated
by this Agreement.

          (b) The authorized capital stock of each of the Subsidiaries consists
of the number and type of shares of capital stock set forth on Schedule 3.2(b)
(collectively, "Subsidiary Stock"). Schedule 3.2(b) also sets forth the number
and type of shares of Subsidiary Stock which are issued and outstanding
(collectively, "Subsidiary Shares"), the securities of any other corporation
owned by the Company or any of the Subsidiaries, as well as the names of any
joint venture, partnership or other noncorporate entity in which the Company or
any of the Subsidiaries is a participant. The Subsidiary Shares are all of the
issued and outstanding shares of capital stock of the Subsidiaries and are
directly or ultimately owned by the Company, free and clear of any Liens other
than restrictions imposed by applicable securities laws, and have been duly
authorized and validly issued and are fully paid and nonassessable and free of
preemptive rights. Also set forth on Schedule 3.2(b) is a listing of all names
under which the Company and the Subsidiaries have done business within the five
(5) year period ending on the date of this Agreement, as well as the names of
all predecessors of the Company and the Subsidiaries, including the names of any
entities from whom the Company or the Subsidiaries previously acquired
significant assets within the five (5) year period ending on the date of this
Agreement. There are, as of the date hereof, no Commitments obligating any of
the Subsidiaries to issue any additional shares of capital stock of any such
Subsidiaries, or any other securities convertible into or evidencing the right
to subscribe for any shares of capital stock of any such Subsidiary.

     SECTION 3.3. AUTHORIZATION. The Company has the requisite corporate power
and authority to execute and deliver this Agreement and to consummate the
transactions contemplated by this Agreement. The Company Stockholders and the
Board of Directors of the

except where the failure to so administer the Company Benefit Plans or to comply
with such laws would not have, individually or in the aggregate, a Company
Material Adverse Effect. There are no pending or, to the Company Stockholders'
Knowledge, threatened investigations by any governmental entity, termination
proceedings, or other, suits or proceedings against or involving any Company

reasonably expected to have, individually or in the aggregate, a Company
Material Adverse Effect.

          (f) Neither the Company nor any of the Subsidiaries maintains or
contributes to any Company Welfare Plan that could not be unilaterally
terminated by the Company or any of the Subsidiaries at any time without
liability.

Company Benefit Plan that are not readily tradeable on a national securities

                      REPRESENTATIONS AND WARRANTIES OF IES

          IES represents and warrants to the Company Stockholders as follows
upon execution of this Agreement and as of the Effective Time:

     SECTION 4.1. ORGANIZATION AND QUALIFICATION. Each of IES and Acquisition is
a corporation duly organized, validly existing and in good standing under the
laws of the state of its incorporation, and IES has the requisite corporate
power to carry on its business as it is now conducted. IES is duly qualified to
conduct business as a foreign corporation in each jurisdiction in which its
ownership or lease of property or the conduct of its business and operations
makes such qualification necessary, except for such jurisdictions in which IES's
failure to be so qualified is not reasonably expected to have, individually or
in the aggregate, an IES Material Adverse Effect (as defined in Section 10.16).

     SECTION 4.2. CAPITALIZATION. (a) The authorized capital stock of IES
consists of 100,000,000 shares of IES Common Stock, 2,655,709 shares of
restricted voting common stock and 10,000,000 shares of preferred stock. As of
March 31, 1998, there were outstanding 21,759,627 shares of IES Common Stock
(including no shares of treasury stock), 2,655,709 shares of restricted voting
common stock, and no shares of preferred stock. All outstanding shares of
capital stock of IES have been duly authorized and validly issued and are fully
paid and non-assessable and free of preemptive rights.

          (b) The shares of IES Common Stock to be issued as part of the Merger
Consideration have been duly authorized and, when issued and delivered in
accordance with the terms of this Agreement, will have been validly issued and
will be fully paid and non-assessable, and the issuance thereof is not subject
to any preemptive or other similar right. The delivery of the Merger
Consideration to the Company Stockholders pursuant to the terms of this
Agreement will transfer valid title thereto, free and clear of all Liens.

     SECTION 4.3. AUTHORIZATION. The execution, delivery and performance by IES
of this Agreement, and the consummation by IES and Acquisition of the
transactions contemplated hereby, are within the corporate powers of IES and
Acquisition and have been duly authorized by all necessary corporate action. No
other corporate proceedings on the part of IES or Acquisition are necessary to
authorize the execution and delivery of this Agreement or the consummation by
IES and Acquisition of the transaction contemplated hereby. This Agreement has
been duly authorized, executed and delivered by IES and Acquisition and
constitutes the valid and binding obligation of IES and Acquisition enforceable
against IES and Acquisition in accordance with its terms.

     SECTION 4.4. CONSENTS AND APPROVAL; NO VIOLATION. Neither the execution and
delivery of this Agreement by IES and Acquisition, nor the consummation by IES
and Acquisition of the transactions contemplated by this Agreement, will: (a)
require any consent, approval, authorization, or permit of, or filing with or
notification to, any Governmental 




                                     - 18 -

Authority, except (i) the filing of articles of merger in accordance with South
Carolina Law, (ii) compliance with any applicable requirements of the 1933 Act,
the Securities Exchange Act of 1934, as amended (the "1934 Act"), and foreign or
state securities or Blue Sky laws, (iii) any regulatory approvals or routine
governmental consents normally acquired after the consummation of transactions
such as transactions of the nature contemplated by this Agreement, (iv) where
the failure to obtain such consent, approval, authorization, or permit, or to
make such filing or notification, is not reasonably expected to have,
individually or in the aggregate, an IES Material Adverse Effect or prevent or
delay, in any material respect, the consummation of the transactions
contemplated by this Agreement or (v) approvals required pursuant to the HSR
Act; (b) result in a default (or give rise to any right of termination,
cancellation, or acceleration) under any of the terms, conditions, or provisions
of any agreement or other instrument binding upon IES or any of its
subsidiaries, except for such defaults (or rights of termination, cancellation,
or acceleration) as to which requisite waivers or consents have been obtained or
which are not reasonably expected to have, individually or in the aggregate, an
IES Material Adverse Effect or prevent or delay, in any material respect, the
consummation of the transactions contemplated by this Agreement; or (c) assuming
compliance with the matters referred to in Section 4.4(a), violate any order,
writ, injunction, decree, statute, rule, or regulation applicable to IES or any
of its subsidiaries or any of their assets, except for violations which are not
reasonably expected to have, individually or in the aggregate, an IES Material
Adverse Effect or prevent or delay, in any material respect, the consummation of
the transactions contemplated by this Agreement. Neither IES nor Acquisition is
in violation of their Articles of Incorporation or Bylaws, and the consummation
of the transactions contemplated by this Agreement will not result in violation
of the Articles of Incorporation or Bylaws of either of them.

     SECTION 4.5. SEC FILINGS. (a) IES has filed with the Securities and

all material respects with the applicable requirements of the 1934 Act.

          (c) As of its filing date, each IES SEC Filing filed pursuant to the
1934 Act did not contain any untrue statement of a material fact or omit to

          (d) IES has previously delivered to the Company Stockholders copies of
IES's prospectus, dated April 30, 1998, as supplemented (the "Prospectus"). As
of its date, the Prospectus did not contain any 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, in light of the circumstances under which they
were made, not misleading.

following has been represented, guaranteed, or warranted to either of them by
Company or Company Stockholders or their agents or employees, or any other
person, expressly or by implication:

of the shares of Company Common Stock;

          (b) that the past performance or experience on the part of company, or
any officer, director or affiliate, their partners, salesmen, associates,
agents, or employees, or any other person, will in any way guarantee the actual
results of the ownership of the shares of Company Common Stock; or

          (c) that any projections, budgets, forecasts or other forward looking
information constitute a guarantee, representation or warranty that such
predictions, forecasts or information can, or will, be achieved.

          (a) The Company Stockholders shall file or cause to be filed all tax

but in each case only after IES has reviewed such filings and consented thereto,
which consent shall not be unreasonably withheld. Such Company tax returns shall

affiliates to, provide to each of the other parties hereto such cooperation and
information as any of them reasonably may request in filing any tax returns,
amended tax returns or claim for refund, determining a liability for Taxes or a

respect of Taxes. Such cooperation and information shall include providing
copies of all relevant portions of relevant tax returns, together with relevant
accompanying schedules and relevant work papers, relevant documents relating to
rulings or other determinations by taxing authorities and relevant records

Section 1374 of the Code caused in connection with the deemed 



                                     - 22 -
<PAGE>   28

sale of the Company's assets (including the assets of any qualified subchapter S
subsidiary) caused by a Section 338(h)(10) Election. The Company Stockholders
will include any income, gain, loss, deduction, or other tax item resulting from
the Section 338(h)(10) Election on their Tax returns to the extent permitted by
applicable law. On or before March 15, 1999, the certified public accounting
firm of Elliott Davis & Company, Greenville, South Carolina shall calculate each
Company Stockholder's federal and state income taxes for calendar year 1998 both
with a Section 338(h)(10) election and without a Section 338(h)(10) Election. If
a Company Stockholder's federal and state income taxes calculated with a Section
338(h)(10) Election exceeds the Company Stockholder's federal and state income
taxes without a Section 338(h)(10) Election, then IES shall have the opportunity
to review such calculation and, if in agreement, shall pay the difference to
such Company Stockholder within thirty (30) days following receipt of Elliot
Davis & Company's written calculations to such account as the Company
Stockholder shall direct. If the parties are unable to agree upon such
calculation, they shall mutually pick an independent "Big Six" accounting firm
to make such calculation, which calculation equally shall be binding upon both
parties. The parties shall split equally the fees and expenses of such

                                   ARTICLE VI

                                 INDEMNIFICATION

          The Company Stockholders and IES each make the following covenants:

     SECTION 6.1. INDEMNIFICATION BY THE COMPANY STOCKHOLDERS. The Company
Stockholders covenant and agree that they, jointly and severally, will
indemnify, defend, and hold harmless IES, the Company, and the Surviving
Corporation, and their respective officers, directors, employees, stockholders,
agents, representatives, and affiliates (the "IES Indemnitees") at all times
from and after the date of this Agreement from and against all claims, damages,
losses, liabilities (joint or several), obligations, penalties, defenses,
actions, lawsuits, proceedings, judgments, demands, assessments, adjustments,
costs, and expenses (including specifically, but without limitation, reasonable
fees, disbursements, and expenses of attorneys, accountants, other professional
advisors and of expert witnesses and costs of investigation and preparation)
(collectively, "Damages"), as they are incurred resulting from, relating to or
arising out of:

              (a) any breach of or any allegation or claim by a third party
     which, if true, would constitute a breach of any representation or warranty
     of Company Stockholders set forth herein or in the Schedules or
     certificates delivered in connection herewith;

              (b) any breach or non-performance, partial or total, by the
     Company or any of the Company Stockholders of any covenant or agreement of
     the Company (or any affiliate or subsidiary thereof) or the Company
     Stockholders (or any affiliate or subsidiary thereof) contained in this
     Agreement, other than Company obligations due after Closing; or

              (c) the remediation, cleanup, testing, analysis, removal,
     containment, treatment, storage, disposal, release or other action required
     by law or expense related to items, if any, set forth or described by
     Schedule 3.18.

          Notwithstanding anything in this Agreement to the contrary, any
Damages or other indemnification amounts owed or incurred by Company
Stockholders, on the one hand, or IES on the other hand, in this Agreement shall
be reduced by (i) reserves established by Company as of June 30, 1998 with
regard to a specific indemnity obligation, (ii) any insurance proceeds received
by Surviving Corporation or IES, on the one hand, or the Company Stockholders,
on the other hand, under insurance coverage; and (iii) any resulting tax
benefits.

          Notwithstanding any provision to the contrary in this Agreement, in no
event whatsoever shall the aggregate liability of the Company Stockholders, on
the one hand, or IES, on the other hand, under this Agreement (including all
costs, expenses and attorneys' fees paid or incurred by IES, the Company and/or
the Company Stockholders in connection therewith or with respect to any
indemnification or the curing of any and all misrepresentations or breaches
under 




                                     - 29 -
<PAGE>   35

this Agreement) exceed $18,000,000; provided, however, that the foregoing
limitation on liability shall not apply with respect to (i) indemnity
obligations under Section 6.1(a) relating to Section 3.2, Section 3.19 hereof or
(ii) with respect to indemnity obligations under Section 6.3(a) relating to
Section 4.2(b) hereof or (iii) the failure of IES and/or Acquisition to pay all
or any part of the Merger Consideration; (iv) with respect to any Damages that
relate to or occur as a result of fraudulent misrepresentations or fraudulent
actions; or (v) with respect to IES's obligations pursuant to Section 5.6.

     SECTION 6.2. INDEMNIFICATION RELATED TO TAX LIABILITIES. Except for any Tax
under Section 1374 of the Code, the Company Stockholders shall retain liability,
and shall indemnify IES, for the payment of any Tax liabilities with respect to
the conduct of the business of the Company or the Subsidiaries during all
periods ending as of the day immediately prior to the Effective Time.
Notwithstanding any provision in this Agreement to the contrary, IES and
Surviving Corporation shall pay and be responsible for all taxes under Section
1374 of the Code incurred by Company due to the transactions described in this
Agreement, and Company's failure to have adequate Tax reserves for such Taxes
shall not be deemed a breach of any representation, warranty or covenant in this
Agreement. Further, if Section 5.20 hereof was complied with and a Company
Stockholder's 1998 federal and/or state income Tax liability is subsequently
increased by the Internal Revenue Service or any state income Tax authority
above the greater of the amount of income taxes determined by Elliott Davis &
Company (a) with a Section 338(h)(10) Election and (b) without a Section
338(h)(10) Election, as a result of a successful challenge to a purchase price
reallocation resulting from the Section 338(h)(10) Election, IES will indemnify
and hold harmless each Company Stockholder for any resulting income tax,
penalties and interest within fifteen (15) days after such Company Stockholder
has paid such additional income Tax.

     SECTION 6.3. INDEMNIFICATION BY IES. IES covenants and agrees that it will
indemnify, defend, and hold harmless the Company Stockholders (the "Stockholder
Indemnitees") at all times from and after the date of this Agreement from and
against all claims, damages, losses, liabilities (joint or several),
obligations, penalties, defenses, actions, lawsuits, proceedings, judgments,
demands, assessments, adjustments, costs, and expenses (including specifically,
but without limitation, reasonable fees, disbursements, and expenses of
attorneys, accountants, other professional advisors and of expert witnesses and
costs of investigation and preparation), (collectively, "Damages"), as they are
incurred, resulting from, relating to or arising out of:

              (a) any breach of or any allegation or claim by a third party
     which, if true, would constitute a breach of any representation or warranty
     of IES and/or Acquisition set forth herein or in the Schedules or
     certificates delivered in connection herewith; and

              (b) any breach or non-performance, partial or total, by IES of any
     covenant or agreement of IES (or any affiliate or subsidiary thereof)
     contained in this Agreement.





                                     - 30 -
<PAGE>   36

              (c) the failure of IES and Surviving Corporation to fulfill their
     obligations described in Section 5.6.

     SECTION 6.4. INDEMNIFICATION PROCEEDINGS. Promptly after a party
indemnified pursuant to this Article VI ("Indemnitee") has received notice of or
has knowledge of any claim by a person not a party to this Agreement ("third
party") or the commencement of any action or proceeding by a third party, the
Indemnitee shall promptly, and in any event within fifteen (15) days of the
assertion of any claim or the discovery of any fact upon which Indemnitee
intends to base a claim for indemnification under this Agreement ("Indemnitee
Claim"), as a condition precedent to the Indemnitee Claim, give written notice
to the party or parties from whom indemnification is sought ("Indemnitor") of
such claim by the third party. Such notice shall state the nature and the basis
of such claim and a reasonable estimate of the amount thereof. In the event of
any Indemnitee Claim, Indemnitor, at its option, shall have the right to defend
or settle, at its own expense and by its own counsel, any such matter so long as
the Indemnitor pursues the same in good faith and diligently. If the Indemnitor
undertakes to defend or settle, it shall promptly notify the Indemnitee of its
intention to do so, and the Indemnitee shall cooperate with the Indemnitor and
its counsel in the defense thereof and in any settlement thereof.
Notwithstanding the foregoing, the Indemnitee shall have the right to
participate in any matter through counsel of its own choosing at Indemnitee's
own expense; provided that the Indemnitor's counsel shall always be lead counsel
and shall determine all litigation and settlement steps, strategy and the like.
Except as set forth in the preceding sentence, after the Indemnitor has notified
the Indemnitee of its intention to undertake to defend or settle any such
asserted liability, and for so long as the Indemnitor diligently pursues such
defense, the Indemnitor shall not be liable for any additional legal expenses
incurred by the Indemnitee in connection with any defense or settlement of such
asserted liability, except to the extent such participation is requested by the
Indemnitor, in which event the Indemnitee shall be reimbursed by the Indemnitor
for reasonable additional legal expenses and out-of-pocket expenses. If the
Indemnitor desires to accept a final and complete settlement of any such third
party claim and the Indemnitee refuses to consent to any such settlement which
contains a complete and irrevocable release of Indemnitee of all current and
future claims related to or arising out of the matter in dispute, then the
Indemnitor's liability under this Section with respect to such third party claim
shall be limited to the amount so offered in settlement by said third party. If
the Indemnitor does not undertake to defend such matter to which the Indemnitee
is entitled to indemnification hereunder, or fails diligently to pursue such
defense, the Indemnitee may undertake such defense through counsel of its
choice, at the cost and expense of the Indemnitor, and the Indemnitee may settle
such matter, without the consent of the Indemnitor, and the Indemnitor shall
immediately reimburse the Indemnitee for the amount paid in such settlement and
any other liabilities or expenses incurred (including all reasonable legal fees
and expenses) by the Indemnitee in connection therewith as such amounts,
liabilities, expenses and fees are incurred.

     SECTION 6.5. SOLE REMEDY. In the absence of fraud or fraudulent
misrepresentation, the indemnification provisions set forth in this Article VI
shall be the exclusive basis for the assertion of a monetary claim pursuant to
the Agreement or for the breach of a representation or warranty made pursuant to
this Agreement.




                                     - 31 -
<PAGE>   37

     SECTION 6.6. LIMITATIONS AND EXCEPTIONS. Notwithstanding any provision of
this Agreement to the contrary, neither Company nor the Company Stockholders
shall be liable or responsible in any manner to IES or Acquisition whether for
indemnification or otherwise, except for the indemnity as expressly provided for
in this Article VI. Neither party nor parties shall have any liability under
this Article VI with respect to any Damages to the extent that such Damages are
caused by the failure of the other party or parties to provide prompt notice as
provided in Section 6.4.

     SECTION 6.7. NO THIRD PARTY BENEFICIARIES. The foregoing indemnification is
given solely for the purpose of protecting the IES Indemnitees and the
Stockholder Indemnitees and shall not be deemed extended to, or interpreted in a
manner to confer any benefit, right, or cause of action upon, any other Person.

     SECTION 6.8. LIMITATION UPON INDEMNITY. The Company Stockholders, on the
one hand, and IES, on the other hand, shall be entitled to indemnification from
the other under the provisions of this Article VI for all claims subject to
indemnification by such party, but only after such time that the amount of, and
to the extent that, such claims for which the Indemnitee is entitled to be paid
exceed, in the aggregate, $500,000, (the "Indemnification Threshold") at which
time the indemnifying parties shall be liable for all Damages in excess of (but
not including) the Indemnification Threshold; provided, however, that the
foregoing limitation on liability shall not apply with respect to (a) indemnity
obligations under (i) Section 6.1(a) relating to Section 3.2, (ii) any item
disclosed on Schedule 3.18 hereto and (iii) Section 3.19 hereof, or (b) 
indemnity obligations under Section 6.3(a) relating to Section 4.2(b), or (c)
indemnity obligations under Section 6.2, or (d) obligations under Section 5.17,
or (e) indemnity obligations under Section 6.3(c) relating to Section 5.6, or
(f) obligations under Section 5.11(d), or (g) the failure of IES and/or
Acquisition to pay all or any part of the Merger Consideration; or (h) with
respect to any Damages that relate to or occur as a result of fraudulent
misrepresentations or fraudulent acts. 

     SECTION 6.9. PUNITIVE DAMAGES. Notwithstanding anything in this Agreement,
in the absence of fraud or fraudulent acts, no party hereto shall be entitled to
any punitive damages from any other party hereto. 

                                   ARTICLE VII

                            NONCOMPETITION COVENANTS

     SECTION 7.1. PROHIBITED ACTIVITIES. The Company Stockholders will not, for
a period of five (5) years following the Effective Time, directly or indirectly,
for themselves or on behalf of or in conjunction with any other Person:

              (a) engage, as an officer, director, shareholder, owner, partner,
     joint venturer, or in a managerial or advisory capacity, whether as an
     employee, independent contractor, consultant, or advisor, or as a sales
     representative, in any business offering 




                                     - 32 -
<PAGE>   38

     electrical contracting or instrumentation in direct competition with IES or
     any of its subsidiaries within 100 miles of where IES or any of its
     subsidiaries conducts business, including any territory serviced by IES or
     any of its subsidiaries (which subsidiaries, for purposes of this Article
     VII, shall include, without limitation, the Company) (the "Territory");

              (b) except for Scottie Woods and Frank Mew, call upon any Person
     who is, at that time, within the Territory, an employee of IES or any of
     its subsidiaries for the purpose or with the intent of enticing such
     employee away from or out of the employ of IES or any of its subsidiaries;

              (c) call upon any Person who is, at that time, or which has been,
     within one (1) year prior to that time, a customer of IES or any of its
     subsidiaries within the Territory for the purpose of soliciting or selling
     electrical contracting or instrumentation services or products in direct
     competition with IES or any of its subsidiaries within the Territory;

              (d) call upon any prospective acquisition candidate, on any
     Company Stockholder's own behalf or on behalf of any competitor in the
     electrical contracting or instrumentation business, which candidate, to the
     actual knowledge of such Stockholder after due inquiry, was called upon by
     IES or any subsidiary thereof or for which, to the actual knowledge of such
     Company Stockholder after inquiry, IES or any subsidiary thereof made an
     acquisition analysis, for the purpose of acquiring such entity; or

              (e) 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 or as required by law or legal process.

          Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Company Stockholder from acquiring, as a passive investor with
no involvement in the operations of the electrical contracting or
instrumentation business, not more than two percent (2%) of the capital stock of
a business providing services similar to those provided by IES whose stock is
publicly traded on a national securities exchange or over the counter.

     SECTION 7.2. EQUITABLE RELIEF. Because of the difficulty of measuring
economic losses to IES as a result of a breach of the foregoing covenant, and
because of the immediate and irreparable damage that could be caused to IES for
which it would have no other adequate remedy, each Company Stockholder agrees
that the foregoing covenant may be enforced by IES by injunctions, restraining
orders, and other equitable actions and agrees to waive any requirement for the
securing or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief.

     SECTION 7.3. REASONABLE RESTRAINT. It is agreed by the parties hereto that
the foregoing covenants in this Article VII impose a reasonable restraint on the
Company 




                                     - 33 -
<PAGE>   39

Stockholders in light of the activities and business of IES on the date of the
execution of this Agreement and the current plans of IES; but it is also the
intent of IES and the Company Stockholders that such covenants be construed and
enforced in accordance with the changing activities, business, and locations of
IES and its subsidiaries throughout the term of this covenant.

     SECTION 7.4. SEVERABILITY; REFORMATION. The covenants in this Article VII
are severable and separate, and the unenforceability of any specific covenant
shall not affect the continuing validity and enforceability of any other
covenant. In the event any court of competent jurisdiction shall determine that
the scope, time or territorial restrictions set forth in this Article VII 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 this
Agreement shall thereby be reformed.

     SECTION 7.5. MATERIAL AND INDEPENDENT COVENANT. The Company Stockholders
acknowledge that their agreements with the covenants set forth in this Article
VII are material conditions to IES's agreement to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. All of the
covenants in this Article VII 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 any Company Stockholder against IES or one of its subsidiaries,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by IES of such covenants. It is specifically agreed
that the five (5) year period during which the agreements and covenants of each
Company Stockholder made in this Article VII shall survive shall be computed by
excluding from such computation any time during which such Company Stockholder
is in violation of any provision of this Article VII. The covenants contained in
this Article VII shall not be affected by any breach of any other provision
hereby by any party hereto.

     SECTION 7.6. MATERIALITY. The Company and the Stockholders hereby agree
that this covenant is a material and substantial part of this transaction.

                                  ARTICLE VIII

                APPLICABLE SECURITIES LAWS/TRANSFER RESTRICTIONS

     SECTION 8.1. COMPANY STOCKHOLDERS' REPRESENTATIONS AND WARRANTIES
CONCERNING SECURITIES. As of the date hereof (which is the same date as the
Effective Time), the Company Stockholders hereby make the following
representations and warranties to and for the benefit of IES: (i) that the
Company Stockholders have been provided with copies of the Prospectus and have
been provided as much time and opportunity as they deemed appropriate to review
and study such Prospectus, and to consult with IES regarding the merits and
risks of the transactions contemplated by this Agreement; (ii) that the Company
Stockholders have had adequate opportunity to ask questions of and receive
answers from the officers of IES pertaining to the purchase of the IES Common
Stock pursuant to the Merger, and (iii) all such questions have been answered to
the satisfaction of the Company Stockholders, but receiving such information and
receiving such answers does not diminish in any respect the representations,
warranties and covenants of IES and Acquisition hereunder. The Company
Stockholders acknowledge that the shares of IES Common Stock to be delivered to
the Company Stockholders pursuant to this Agreement have not been registered
under the 1933 Act and therefore may not be resold without compliance with the
1933 Act. The IES Common Stock to be acquired by such Company Stockholders
pursuant to this Agreement is being acquired solely for their own respective
accounts, for investment purposes only, and with no present intention of
distributing, selling or otherwise disposing of it in connection with a
distribution. The Company Stockholders are able to bear the economic risk of an
investment in the IES Common Stock to be acquired pursuant to this Agreement and
can afford to sustain a total loss of such investment. Each Company Stockholder
has substantial knowledge and experience in making investment decisions of this
type (or is relying on qualified purchaser representatives with such knowledge
and experience in making this decision), and is capable, either individually or
with such purchaser representatives, of evaluating the merits and risks of this
investment. Each Company Stockholder is an "accredited investor" as defined in
Rule 501(a) of the 1933 Act.

     SECTION 8.2. TRANSFER RESTRICTIONS. Unless otherwise agreed by IES, except
for transfers to immediate family members who agree to be bound by the
restrictions set forth in this Section 8.2 (or trusts for the benefit of the
Company Stockholders or family members, or trusts in which a Company Stockholder
is both the grantor and the beneficiary, the trustees of which so agree) and
except in the event of the death of a Company Stockholder, for a period of two
years from the date of this Agreement, none of the Company Stockholders shall
sell, assign, exchange, transfer, appoint, or otherwise dispose of any shares of
IES Common Stock received by the Company Stockholders pursuant to this
Agreement. The certificates evidencing the IES Common Stock delivered to the
Company Stockholders pursuant to this Agreement will bear a legend substantially
in the form set forth below and containing such other information as IES may
deem necessary or appropriate:

     THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, ASSIGNED,
     EXCHANGED, TRANSFERRED, DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF
     WITHOUT THE WRITTEN CONSENT OF IES, AND THE ISSUER SHALL NOT BE REQUIRED TO
     GIVE EFFECT TO ANY ATTEMPTED SALE, ASSIGNMENT, EXCHANGE, TRANSFER,
     DISTRIBUTION, APPOINTMENT OR OTHER DISPOSITION PRIOR TO THE SECOND




                                     - 35 -
<PAGE>   41

     ANNIVERSARY OF THE EFFECTIVE TIME. UPON THE WRITTEN REQUEST OF THE HOLDER
     OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE THIS RESTRICTIVE LEGEND
     (AND ANY STOP ORDER PLACED WITH THE TRANSFER AGENT) AFTER THE DATE
     SPECIFIED ABOVE. 

     SECTION 8.3. RESALES. (a) In the event of the death of a Company
Stockholder, to the extent that any Company Stockholder's estate desires to sell
any IES Common Stock received by such Company Stockholder pursuant to this
Agreement within a period of two (2) years from the date of this Agreement, IES
shall, as soon as reasonably practicable, use reasonable efforts to register
such stock for resale under its current acquisition shelf registration statement
(or any successor acquisition shelf registration statement) and ensure that such
registration statement remains available for resales of such stock.

          (b) With a view to making available the benefits of certain rules and
regulations of the SEC that may permit the sale of the IES Common Stock received
hereunder to the public without registration, IES agrees to use its reasonable
efforts to:

              (i) make and keep public information regarding IES available as
     those terms are understood and defined in Rule 144 under the 1933 Act for a
     period of two years and 3 months following the Effective Time; and

              (ii) file with the SEC in a timely manner all reports and other
     documents required of IES under the 1933 Act and the 1934 Act.

                                   ARTICLE IX

                    NONDISCLOSURE OF CONFIDENTIAL INFORMATION

     SECTION 9.1. GENERAL. The Company Stockholders recognize and acknowledge
that they had in the past, currently have, and in the future may possibly have,
access to certain confidential information of the Company or the Surviving
Corporation, such as lists of customers or employees, operational policies, and
pricing and cost policies that are valuable, special, and unique assets of the
Company and will be valuable, special, and unique assets of the Surviving
Corporation. The Company Stockholders agree that for a period of two (2) years
following the Closing they will not disclose such confidential information to
any Person for any purpose or reason whatsoever (except such information as the
Company Stockholders may be required to disclose to any Governmental Authority
or to authorized representatives of IES or in accordance with legal process or
in order to enforce the terms of this Agreement). In the event of a breach or
threatened breach by the Company Stockholders of the provisions of this Section,
IES shall be entitled to an injunction restraining the Company Stockholders from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting IES from pursuing any other available remedy
for such breach or threatened breach, including the recovery of damages.





                                     - 36 -
<PAGE>   42

     SECTION 9.2. EQUITABLE RELIEF. Because of the difficulty of measuring
economic losses as a result of the breach of the foregoing covenants, and
because of the immediate and irreparable damage that would be caused for which
the Company, the Surviving Corporation, and/or IES would have no other adequate
remedy, the Company Stockholders agree that the foregoing covenants may be
enforced against them by injunctions, restraining orders, and other equitable
actions and agree to waive any requirement for the securing or posting of any
bond in connection with the obtaining of any such injunctive or other equitable
relief.

     SECTION 9.3. NON-PUBLIC INFORMATION. The Company Stockholders hereby
acknowledge that if they become aware of "material non-public information" (as
defined under applicable securities laws) regarding IES, that they will be
required, under applicable securities laws, to refrain from trading in IES
securities or disclosing any such information while such information is
non-public.

     SECTION 9.4. SURVIVAL. The obligations of the parties under this Article IX
shall survive the Closing of this Agreement.

                                    ARTICLE X

those set forth or referred to herein.

     SECTION 10.3. EXPENSES AND FEES. All costs and expenses incurred in
connection with this Agreement shall be paid by the party incurring such cost or
expense; provided, however, that IES shall pay all costs, including filing fees

and inure to the benefit of the parties hereto and their respective successors
and assigns; provided, however, that no party may assign, delegate, or otherwise

consent of each other party hereto, except IES or Acquisition may transfer or

entitled to rely on any representation, warranty, or covenant contained herein.

     SECTION 10.6. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The

shall survive the consummation of the transactions contemplated hereby and any
examination on behalf of the parties for a period of two years, following which

terms defined herein are equally applicable to both the singular and plural
forms of such terms.

     SECTION 10.8. AMENDMENTS AND WAIVERS. This Agreement may not be modified or
amended except by an instrument or instruments in writing signed by the party
against whom enforcement of any such modification or amendment is sought. Any
party hereto may, only by an instrument in writing, waive compliance by any
other party hereto with any term or provision of this Agreement on the part of
such other party hereto to be performed or complied with. The waiver by any
party hereto of a breach of any term or provision of this Agreement shall not be
construed as a waiver of any subsequent breach.

     SECTION 10.9. CONSTRUCTION OF CERTAIN PROVISIONS. It is understood and
agreed that the specification of any dollar amount in the representations and
warranties contained in this Agreement or the inclusion of any specific item in
the Schedules or Exhibits is not intended to imply that such amounts or higher
or lower amounts, or the items so included or other items, are or are not
material, and no party shall use the fact of the setting of such amounts or the
fact of the inclusion of any such item in the Schedules in any dispute or
controversy between the parties as to whether any obligation, item, or matter
not described herein or included in a Schedule or Exhibit is or is not material
for purposes of this Agreement. It is agreed that neither party shall allege
that a provision of this Agreement shall be construed against a party because
such party drafted such provision.

     SECTION 10.10. SEVERABILITY. If any term or other provision of this
Agreement is invalid, illegal, or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect. Upon such determination that any
term or other provision is invalid, illegal, or incapable of being enforced, the
parties hereto shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties as closely as possible in an
acceptable manner to the end that the transactions contemplated by this
Agreement are fulfilled to the extent possible.

     SECTION 10.11. JURISDICTION. Any legal action, suit, or proceeding in law
or equity arising out of or relating to this Agreement and transactions
contemplated by this Agreement may only be instituted in any state or federal
court in Harris County, Houston, Texas, and each party agrees not to assert, by
way of motion, as a defense, or otherwise, in any such action, suit, or
proceeding, any claim that it is not subject personally to the jurisdiction of
such court, that its property is exempt or immune from attachment or execution,
that the action, suit, or proceeding is brought in an inconvenient forum, that
the venue of the action, suit, or proceeding is improper or that this Agreement,
or the subject matter hereof or thereof may not be enforced in or by such court.
Each party further irrevocably submits to the jurisdiction of any such court in
any such action, suit, or proceeding. Any and all service of process and any
other notice in any such action, suit, or proceeding shall be effective against
any party if given by registered or certified mail, return receipt requested, or
by any other means of mail which requires a signed receipt, postage prepaid,
mailed to such party at the address listed in Section 10.4. Nothing herein
contained shall be deemed to affect the right of any party to serve process in
any manner permitted by law.

of this Agreement, it shall not be necessary to produce or account for more than

parties an original, duly executed counterpart of this Agreement.

         1.3     Accounting Terms; Preparation of Financials.

                 (a)      All accounting terms, definitions, ratios, and other
tests described herein shall be construed in accordance with United States
generally accepted accounting principles applied on a consistent basis with
those applied in the preparation of the Registration Statement, except as
expressly set forth in this Agreement.

                 (b)      The Restricted Entities shall prepare their financial
statements in accordance with United States generally accepted accounting
principles applied on a consistent basis with those applied in the preparation
of the Registration Statement, unless otherwise approved in writing by the
Agent.  In accordance with the foregoing, (i) any Acquisition which is
permitted to be treated as a pooling transaction shall be treated as a pooling
transaction, and following such an Acquisition the consolidated financial
statements of the Borrower shall be adjusted to reflect the results of such
Acquisition during the periods prior to such Acquisition in accordance with
generally accepted accounting principles and (ii) any Acquisition which is not
permitted to be treated as a pooling transaction shall be treated as an asset
purchase, without adjustment for prior periods.

                 (c)      Where expressly permitted in this Agreement, the
Borrower may elect to use the compliance calculations set forth in Schedule C
of a Compliance Certificate to calculate the Applicable Margin or compliance
with a financial covenant under this Agreement.  In such case the accounting
terms, definitions, ratios, and other tests used in making such calculation
shall be construed as required by paragraph (a) above except that the
consolidated financial results of the Borrower shall be deemed to be the
adjusted consolidated financial results of the Borrower set forth in Schedule B
of the Compliance Certificate.  The Borrower shall prepare Schedule B and C of
the Compliance Certificate in accordance with the following provisions:

                          (i)     The Borrower may select one or more
         Acquisitions for inclusion in the adjustments permitted in Schedule B
         or C of the Compliance Certificate; provided that if the inclusion of
         any Acquisition results in an increase in the consolidated EBITDA of
         the Borrower over the consolidated EBITDA of the Borrower required to
         be reported in Schedule A of the Compliance Certificate, then the
         Borrower must include all Acquisitions which would cause a decrease in
         the consolidated EBITDA of the Borrower in Schedule B and C of the
         Compliance Certificate.

<PAGE>   22
                          (ii)    If the Acquisition is treated as a pooling
         transaction, the Borrower shall adjust the pooling accounting
         treatment of the Acquisition to reflect nonrecurring items (both
         positive and negative) that are permitted to be adjusted in accordance
         with the pro forma financial statement guidelines established by the
         Securities and Exchange Commission for acquisition accounting for
         reported acquisitions by public companies or as approved by the Agent.

                          (iii)   If the Acquisition is not treated as a
         pooling transaction, the financial results of the acquired Person or
         assets shall be added to the applicable financial results of the
         Borrower in the same manner as if such transaction were a pooling
         transaction with such adjustments thereto as are required to reflect
         nonrecurring items (both positive and negative) that are permitted to
         be adjusted in accordance with the pro forma financial statement
         guidelines established by the Securities and Exchange Commission for
         acquisition accounting for reported acquisitions by public companies
         or as approved by the Agent.

                          (iv)    No Acquisition may be included in Schedule B
         or C of the Compliance Certificate at the request of the Borrower
         unless the financial reports of the acquired Person or assets from
         which Schedule B and C are prepared are (A) audited financial reports
         prepared by an independent certified public accounting firm, or (B)
         with respect to unaudited financial reports, are otherwise approved by
         the Agent.

         1.4     Types.  The "Type" of a Tranche refers to the determination
whether such tranche is a LIBOR Tranche or the Prime Rate Tranche.

         1.5     Interpretation.  Article, Section, Schedule, and Exhibit
references are to this Agreement, unless otherwise specified.  All references
to instruments, documents, contracts, and agreements are references to such
instruments, documents, contracts, and agreements as the same may be amended,
supplemented, and otherwise modified from time to time, unless otherwise
specified.  The word "including" shall mean "including but not limited to."
The word "or" shall mean "and/or" wherever necessary to prevent interpretation
of any provision against the Agent or the Banks.  Whenever the Borrower has an
obligation under this Agreement and the Credit Documents the expense of
complying with that obligation shall be an expense of the Borrower unless
otherwise specified.  Whenever any determination is to be made by the Agent or
any Bank, such determination shall be in such Person's sole discretion unless
otherwise specified in this Agreement.  If any provision in this Agreement and
the Credit Documents is held to be illegal, invalid, not binding, or
unenforceable, such provision shall be fully severable and this Agreement and
the Credit Documents shall be construed and enforced as if such illegal,
invalid, not binding, or unenforceable provision had never comprised a part of
this Agreement and the Credit Documents, and the remaining provisions shall
remain in full force and effect.  This Agreement and the Credit Documents have
been reviewed and negotiated by sophisticated parties with access to legal
counsel and shall not be construed against the drafter.  In the event of a
conflict between this Agreement and any other Credit Documents, this Agreement
shall control.

ARTICLE 2.       CREDIT FACILITIES.

         2.1     Revolving Loan Facility.

                 (a)      Revolving Loan Commitments.  Each Bank severally
agrees, on the terms and conditions set forth in this Agreement and for the
purposes set forth in Section 5.4, to make  Revolving Loan Advances to the
Borrower as such Bank's ratable share of Revolving Loan Borrowings requested by
the Borrower from time to time on any Business Day during the period from the
date of this Agreement until the Revolving Loan Maturity Date provided that the
aggregate outstanding principal amount of Revolving Loan Advances made by such
Bank plus such Bank's ratable share of the Swing Line Loan plus such Bank's
ratable share of the Letter of Credit Exposure shall not exceed such Bank's
Revolving Loan Commitment.  Revolving Loan Borrowings must be made in an amount
equal to or greater than $1,000,000, in the case of any Revolving Loan
Borrowing comprised of a LIBOR Tranche, or $1,000,000, in the case of any Prime
Rate Borrowing, and be made in multiples of $500,000,  in the case of any
Revolving Loan Borrowing comprised of a LIBOR Tranche, or $100,000, in the case
of any Prime Rate Borrowing.  Within the limits expressed in this Agreement,
the Borrower may from time to time borrow, prepay, and reborrow Revolving Loan
Borrowings.  The indebtedness of the Borrower to the Banks resulting from the
Revolving Loan Advances made by the Banks shall be evidenced by Revolving Loan
Notes made by the Borrower.

                 (b)      Method of Advancing

                          (i)     Each Revolving Loan Borrowing shall be made
pursuant to a Revolving Loan Borrowing Request given by the Borrower to the
Agent in writing or by telecopy not later than the time required pursuant to
Section 2.5(a)(i) to select the interest rate basis for the Revolving Loan
Borrowing.  Each Revolving Loan Borrowing Request shall be fully completed and
shall specify the information required therein, and shall be irrevocable and
binding on the Borrower.  Upon receipt of the Revolving Loan Borrowing Request
by the Agent, the Agent shall promptly forward notice of the Revolving Loan
Borrowing to the Banks.  Each Bank shall, before 1:00 p.m. (local time at the
Applicable Lending Office of the Agent) on the date of the requested Revolving
Loan Borrowing, make available from its Applicable Lending Office to the Agent
at the Agent's Applicable Lending Office, in immediately available funds, such
Bank's ratable share of such Revolving Loan Borrowing.  Subject to the
satisfaction of all applicable conditions precedent, after receipt by the Agent
of such funds, the Agent shall, by 4:00 p.m. (local time at the Applicable
Lending Office of the Agent), on the date requested for such Revolving Loan
Borrowing make such Revolving Loan Borrowing available to the Borrower in
immediately available funds at any account of Borrower which is designated in
writing by the Borrower to the Agent.

                          (ii)    Unless the Agent shall have received notice
from a Bank before the date of any Revolving Loan Borrowing that such Bank
shall not make available to the Agent such Bank's ratable share of such
Revolving Loan Borrowing, the Agent may assume that such Bank has





                                      -18-
<PAGE>   24
made its ratable share of such Revolving Loan Borrowing available to the Agent
on the date of such Revolving Loan Borrowing in accordance with paragraph (i)
above and the Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount.  If and to the extent that
such Bank shall not have so made its ratable share of such Revolving Loan
Borrowing available to the Agent, such Bank agrees that it shall pay interest
on such amount for each day from the date such amount is made available to the
Borrower by the Agent until the date such amount is paid to the Agent by such
Bank at the Federal Funds Rate in effect from time to time, provided that with
respect to such Bank if such amount is not paid by such Bank by the end of the
second day after the Agent makes such amount available to the Borrower, the
interest rates specified above shall be increased by a per annum amount equal
to 2.00% on the third day and shall remain at such increased rate thereafter.
Interest on such amount shall be due and payable by such Bank upon demand by
the Agent.  If such Bank shall pay to the Agent such amount and interest as
provided above, such amount so paid shall constitute such Bank's Revolving Loan
Advance as part of such Revolving Loan Borrowing for all purposes of this
Agreement even though not made on the same day as the other Revolving Loan
Advances comprising such Revolving Loan Borrowing.  In the event that such Bank
has not repaid such amount by the end of the fifth day after such amount was
made available to the Borrower, the Borrower agrees to repay to the Agent on
demand such amount, together with interest on such amount for each day from the
date such amount was made available to the Borrower until the date such amount
is repaid to the Agent at the interest rate charged to the Borrower for such
Revolving Loan Borrowing under the terms of this Agreement.

                          (iii)   The failure of any Bank to make available its
ratable share of any Revolving Loan Borrowing shall not relieve any other Bank
of its obligation, if any, to make available its ratable share of such
Revolving Loan Borrowing.  No Bank shall be responsible for the failure of any
other Bank to honor such other Bank's obligations hereunder, including any
failure to make available any funds as part of any Revolving Loan Borrowing.

                 (c)      Prepayment.

                          (i)     The Borrower may prepay the outstanding
principal amount of the Revolving Loan pursuant to written notice given by the
Borrower to the Agent in writing or by telecopy not later than (A) 1:00 p.m.
(local time at the Applicable Lending Office of the Agent) on the third
Business Day before the date of the proposed prepayment, in the case of the
prepayment of any portion of the Revolving Loan which is comprised of LIBOR
Tranches, or (B) 11:00 a.m. (local time at the Applicable Lending Office of the
Agent) on the same Business Day of the proposed prepayment, in the case of the
prepayment of any portion of the Revolving Loan comprised solely of the Prime
Rate Tranche.  Each such notice shall specify the principal amount and Tranche
or Tranches of the Revolving Loan which shall be prepaid, the date of the
prepayment, and shall be irrevocable and binding on the Borrower.  Prepayments
of the Revolving Loan shall be made in integral multiples of  $500,000,  in the
case of prepayments of any LIBOR Tranches, or $100,000, in the case of
prepayments of the Prime Rate Tranche.  If the prepayment would cause the
aggregate outstanding principal amount of any LIBOR Tranche comprising all or
any part of the Revolving





                                      -19-
<PAGE>   25
Loan or the aggregate outstanding principal amount of the Prime Rate Tranche
comprising all or any part of the Revolving Loan, to be less than $1,000,000,
in the case of any such LIBOR Tranche, or $1,000,000, in the case of the Prime
Rate Tranche, the prepayment must be in an amount equal to the entire
outstanding principal amount of such LIBOR Tranche under the Revolving Loan or
the entire outstanding principal amount of the Prime Rate  Tranche under the
Revolving Loan, as the case may be.  Upon receipt of any notice of prepayment,
the Agent shall give prompt notice of the intended prepayment to the Banks.
For each such notice given by the Borrower, the Borrower shall prepay the
Revolving Loan in the specified amount on the specified date as set forth in
such notice.  The Borrower shall have no right to prepay any principal amount
of the Revolving Loan except as provided in this Section 2.1(c)(i).

                          (ii)    Each prepayment of principal of any LIBOR
Tranche under the Revolving Loan pursuant to this Section 2.1(c) shall be
accompanied by payment of all accrued but unpaid interest on the principal
amount prepaid and any amounts required to be paid pursuant to Section 2.6 as a
result of such prepayment.

                 (d)      Repayment.  The Borrower shall pay to the Agent for
the ratable benefit of the Banks the aggregate outstanding principal amount of
the Revolving Loan on the Revolving Loan Maturity Date.

                 (e)      Reduction of Commitments.  The Borrower shall have
the right, upon at least three Business Days' irrevocable notice to the Agent,
to terminate in whole or reduce ratably in part the unused portion of the
Commitments; provided that each partial reduction shall be in the aggregate
amount of $5,000,000 or in integral multiples of $5,000,000 in excess thereof.
Any reduction or termination of the Commitments pursuant to this Section 2.1(e)
shall be permanent, with no obligation of the Banks to reinstate such
Commitments and the commitment fees provided for in Section 2.4(a) shall
thereafter be computed on the basis of the Commitments, as so reduced.

         2.2     Letter of Credit Facility.

                 (a)      Commitment for Letters of Credit.  The Issuing Bank
shall, on the terms and conditions set forth in this Agreement and for the
purposes set forth in Section 5.4, issue, increase, and extend Letters of
Credit at the request of the Borrower from time to time on any Business Day
during the period from the date of this Agreement until the Revolving Loan
Maturity Date provided that (i) the Letter of Credit Exposure shall not exceed
the Letter of Credit Sublimit and (ii) the aggregate outstanding principal
amount of Revolving Loan Borrowings plus the Letter of Credit Exposure plus the
Swing Line Loan shall not exceed the aggregate amount of the Revolving Loan
Commitments.  No Letter of Credit may have an expiration date later than 12
months after its issuance date, and each Letter of Credit which is
self-extending beyond its expiration date must be cancelable upon no more than
30 days notice prior to each extension period given by the Issuing Bank to the
beneficiary of such Letter of Credit.  No Letter of Credit may have an
expiration date later than 12 months after the Revolving Loan Maturity Date
unless approved by the Issuing Bank,





                                      -20-
<PAGE>   26
the Agent, and the Banks.  Each Letter of Credit must be in form and substance
acceptable to the Issuing Bank.  The indebtedness of the Borrower to the
Issuing Bank resulting from Letters of Credit requested by the Borrower shall
be evidenced by the Letter of Credit Applications made by the Borrower.

                 (b)      Requesting Letters of Credit.  Each Letter of Credit
shall be issued, increased, or extended pursuant to a Letter of Credit
Application or Letter of Credit Application Amendment, as applicable, given by
the Borrower to the Issuing Bank in writing or by telecopy promptly confirmed
in writing, such Letter of Credit Application or Letter of Credit Application
Amendment being given not later than 1:00 p.m. (local time at the Applicable
Lending Office of the Agent) on the third Business Day before the date of the
proposed issuance, increase, or extension of the Letter of Credit.  Each Letter
of Credit Application or Letter of Credit Application Amendment shall be fully
completed and shall specify the information required therein (including the
proposed form of the Letter of Credit or change thereto), and shall be
irrevocable and binding on the Borrower.  Upon receipt by the Issuing Bank of
the Letter of Credit Application or Letter of Credit Application Amendment, the
Issuing Bank shall give prompt notice thereof to the Agent, and the Agent shall
promptly inform the Banks of the proposed Letter of Credit or change thereto.
Subject to the satisfaction of all applicable conditions precedent, the Issuing
Bank shall, by 4:00 p.m. (local time at the Applicable Lending Office of the
Agent), on the date requested by the Borrower for the issuance, increase, or
extension of such Letter of Credit issue, increase, or extend such Letter of
Credit to the specified beneficiary.  Upon the date of the issuance, increase,
or extension of a Letter of Credit, the Issuing Bank shall be deemed to have
sold to each other Bank and each other Bank shall be deemed to have purchased
from the Issuing Bank a ratable participation in the related Letter of Credit
or change thereto.  The Issuing Bank shall notify the Agent of each Letter of
Credit issued, increased, or extended and the date and amount of each Bank's
participation in such Letter of Credit, and the Agent shall in turn notify the
Banks.

                 (c)      Reimbursements for Letters of Credit.  With respect
to any Letter of Credit and in accordance with the related Letter of Credit
Application, the Borrower agrees to pay to the Issuing Bank on demand fees due
with respect to such Letter of Credit as specified in Section 2.4(b)).  If the
Borrower does not pay upon demand of the Issuing Bank any amount due to the
Issuing Bank under any Letter of Credit Application, in addition to any rights
the Issuing Bank may have under such Letter of Credit Application, the Issuing
Bank may upon written notice to the Agent request the satisfaction of such
obligation by the making of a Revolving Loan Borrowing.  Concurrently with such
notice to the Agent, the Issuing Bank will use reasonable efforts provide like
notice to the Borrower, provided that failure to provide such notice to the
Borrower at such time shall not invalidate the effectiveness of such request
for a Revolving Loan Borrowing.  Upon such request, the Borrower shall be
deemed to have requested the making of a Revolving Loan Borrowing in the amount
of such obligation and the transfer of the proceeds thereof to the Issuing
Bank.  Such Revolving Loan Borrowing shall be a Prime Rate Borrowing.  The
Agent shall promptly forward notice of such Revolving Loan Borrowing to the
Borrower and the Banks, and each Bank shall, in accordance with the procedures
of Section 2.1(b), other than limitations on the size of Revolving





                                      -21-
<PAGE>   27
Loan Borrowings, and notwithstanding the failure of any conditions precedent,
make available such Bank's ratable share of such Revolving Loan Borrowing to
the Agent, and the Agent shall promptly deliver the proceeds thereof to the
Issuing Bank for application to such Bank's share of the obligations under such
Letter of Credit.  The Borrower hereby unconditionally and irrevocably
authorizes, empowers, and directs the Issuing Bank to make such requests for
Revolving Loan Borrowings on behalf of the Borrower, and the Banks to make
Revolving Loan Advances to the Agent for the benefit of the Issuing Bank in
satisfaction of such obligations.  The Agent and each Bank may record and
otherwise treat the making of such Revolving Loan Borrowings as the making of
Revolving Loan Borrowings to the Borrower under this Agreement as if requested
by the Borrower.  Nothing herein is intended to release the Borrower's
obligations under any Letter of Credit Application, but only to provide an
additional method of payment therefor.  The making of any Revolving Loan
Borrowing under this Section 2.2(c) shall not constitute a cure or waiver of
any Default or Event of Default, other than the payment Default or Event of
Default which is satisfied by the application of the amounts deemed advanced
hereunder, caused by the Borrower's failure to comply with the provisions of
this Agreement or any Letter of Credit Application.

                 (d)      Prepayments of Letters of Credit.  In the event that
any Letters of Credit shall be outstanding according to their terms after the
Revolving Loan Maturity Date, the Borrower shall pay to the Agent an amount
equal to the Letter of Credit Exposure allocable to such Letters of Credit to
be held in the Letter of Credit Collateral Account and applied in accordance
with paragraph (g) below.

                 (e)      Obligations Unconditional.  The obligations of the
Borrower and each Bank under this Agreement and the Letter of Credit
Applications to make payments as required to reimburse the Issuing Bank for
draws under Letters of Credit and to make other payments due in respect of
Letters of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement and the Letter of
Credit Applications under all circumstances, including: (i) any lack of
validity or enforceability of any Letter of Credit Document; (ii) any
amendment, waiver, or consent to departure from any Letter of Credit Document;
(iii) the existence of any claim, set-off, defense, or other right which the
Borrower or any Bank may have at any time against any beneficiary or transferee
of any Letter of Credit (or any Persons for whom any such beneficiary or any
such transferee may be acting), the Issuing Bank, or any other person or
entity, whether in connection with the transactions contemplated in this
Agreement or any unrelated transaction; (iv) any statement or any other
document presented under such Letter of Credit proving to be forged,
fraudulent, invalid, or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect; or (v) payment by the Issuing Bank
under any Letter of Credit against presentation of a draft or certificate which
does not comply with the terms of such Letter of Credit; provided, however,
that nothing contained in this paragraph (d) shall be deemed to constitute a
waiver of any remedies of the Borrower or any Bank in connection with the
Letters of Credit or the Borrower's or such Bank's rights under paragraph (e)
below.





                                      -22-
<PAGE>   28
         (f)     Liability of Issuing Bank.  The Issuing Bank shall not be
liable or responsible for:  (i) the use which may be made of any Letter of
Credit or any acts or omissions of any beneficiary or transferee in connection
therewith; (ii) the validity, sufficiency, or genuineness of documents related
to Letters of Credit, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent, or
forged; (iii) payment by the Issuing Bank against presentation of documents
which do not strictly comply with the terms of a Letter of Credit, including
failure of any documents to bear any reference or adequate reference to the
relevant Letter of Credit; or (iv) any other circumstances whatsoever in making
or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING
BANK'S OWN NEGLIGENCE); except that the Issuing Bank shall be liable to the
Borrower or any Bank to the extent of any direct, as opposed to consequential,
damages suffered by the Borrower or such Bank which the Borrower or such Bank
proves were caused by (A) the Issuing Bank's gross negligence or willful
misconduct in determining whether documents presented under a Letter of Credit
comply with the terms of such Letter of Credit, (B) the Issuing Bank's willful
failure to make or delay in making lawful payment under any Letter of Credit
after the presentation to it of documentation strictly complying with the terms
and conditions of such Letter of Credit or the Issuing Bank's payment of
greater than the maximum amount permitted under any Letter of Credit, or (C)
the Issuing Bank's negligence in the handling of money.

         (g)     Letter of Credit Collateral Account.

                 (i)      If the Borrower is required to deposit funds in the
Letter of Credit Collateral Account pursuant to Sections 2.2(d) or 6.4, then
the Borrower and the Agent shall establish the Letter of Credit Collateral
Account and the Borrower shall execute any documents and agreements, including
the Agent's standard form assignment of deposit accounts, that the Agent
reasonably requests in connection therewith to establish the Letter of Credit
Collateral Account and grant the Agent a first priority security interest in
such account and the funds therein.  The Borrower hereby pledges to the Agent
and grants the Agent a security interest in the Letter of Credit Collateral
Account, whenever established, all funds held in the Letter of Credit
Collateral Account from time to time, and all proceeds thereof as security for
the payment of the Obligations.

                 (ii)     Funds held in the Letter of Credit Collateral Account
shall be held as cash collateral for obligations with respect to Letters of
Credit and promptly applied by the Agent at the request of the Issuing Bank to
any reimbursement or other  obligations under Letters of Credit that exist or
occur.  To the extent that any surplus funds are held in the Letter of Credit
Collateral Account above the Letter of Credit Exposure, during the existence of
an Event of Default the Agent may (A) hold such surplus funds in the Letter of
Credit Collateral Account as cash collateral for the Credit Obligations or (B)
apply such surplus funds to any Credit Obligations in accordance with Section
6.9.  If no Default exists, the Agent shall release to the Borrower at the
Borrower's written request any funds held in the Letter of Credit Collateral
Account above the amounts required by Section 2.2(d).





                                      -23-
<PAGE>   29
                 (iii)    Funds held in the Letter of Credit Collateral Account
shall be invested in money market funds of the Agent or in another investment
if mutually agreed upon by the Borrower and the Agent, but the Agent shall have
no other obligation to make any other investment of the funds therein.  The
Agent shall exercise reasonable care in the custody and preservation of any
funds held in the Letter of Credit Collateral Account and shall be deemed to
have exercised such care if such funds are accorded treatment substantially
equivalent to that which the Agent accords its own property, it being
understood that the Agent shall not have any responsibility for taking any
necessary steps to preserve rights against any parties with respect to any such
funds.

         2.3     Swing Line Facility.

                 (a)      Commitment.  The Swing Line Lender agrees, on the
terms and conditions set forth in the Swing Line Note, to make  advances to the
Borrower under the Swing Line Note.  No Bank shall have any rights thereunder
(but each Bank shall have the obligation to reimburse the Swing Line Lender in
accordance with paragraph (b) below).  The indebtedness of the Borrower to the
Swing Line Lender resulting from the advances under the Swing Line Note made by
the Swing Line Lender shall be evidenced by the Swing Line Note made by the
Borrower.

                 (b)      Reimbursements for Swing Line Loan Obligations.  With
respect to the Swing Line Loan and the interest, premium, fees, and other
amounts owed by the Borrower to the Swing Line Lender in connection with the
Swing Line Note, and in accordance with the terms of the Swing Line Note, the
Borrower agrees to pay to the Swing Line Lender such amounts when due and
payable to the Swing Line Lender under the Swing Line Note.  If the Borrower
does not pay to the Swing Line Lender any such amounts when due and payable to
the Swing Line Lender under the Swing Line Note, in addition to any rights the
Swing Line Lender may have under such Swing Line Note, the Swing Line Lender
may upon written notice to the Agent request the satisfaction of such
obligation by the making of a Revolving Loan Borrowing in the amount of any
such amounts not paid when due and payable.  Concurrently with such notice to
the Agent, the Swing Line Lender will use reasonable efforts provide like
notice to the Borrower, provided that failure to provide such notice to the
Borrower at such time shall not invalidate the effectiveness of such request
for a Revolving Loan Borrowing. Upon such request, the Borrower shall be deemed
to have requested the making of a Revolving Loan Borrowing in the amount of
such obligation and the transfer of the proceeds thereof to the Swing Line
Lender.  Such Revolving Loan Borrowing shall be a Prime Rate Borrowing.  The
Agent shall promptly forward notice of such Revolving Loan Borrowing to the
Borrower and the Banks, and each Bank shall, in accordance with the procedures
of Section 2.1(b), other than limitations on the size of Revolving Loan
Borrowings, and notwithstanding the failure of any conditions precedent, make
available such Bank's ratable share of such Revolving Loan Borrowing to the
Agent, and the Agent shall promptly deliver the proceeds thereof to the Swing
Line Lender for application to such amounts owed to the Swing Line Lender.  The
Borrower hereby unconditionally and irrevocably authorizes, empowers, and
directs the Swing Line Lender to make such requests for Revolving Loan
Borrowings on behalf of the Borrower, and the Banks to make Revolving Loan
Advances to the Agent for the benefit of the Swing Line Lender in satisfaction
of





                                      -24-
<PAGE>   30
such obligations.  The Agent and each Bank may record and otherwise treat the
making of such Revolving Loan Borrowings as the making of a Revolving Loan
Borrowing to the Borrower under this Agreement as if requested by the Borrower.
Nothing herein is intended to release the Borrower's obligations under the
Swing Line Note, but only to provide an additional method of payment therefor.
The making of any Borrowing under this Section 2.3(b) shall not constitute a
cure or waiver of any Default or Event of Default, other than the payment
Default or Event of Default which is satisfied by the application of the
amounts deemed advanced hereunder, caused by the Borrower's failure to comply
with the provisions of this Agreement or the Swing Line Note.

         2.4     Fees.

                 (a)      Commitment Fees.  The Borrower shall pay to the Agent
for the ratable benefit of the Banks an unused commitment fee in an amount
equal to the product of the Applicable Margin for unused commitment fees in
effect from time to time multiplied by the average daily amount by which (i)
the aggregate amount of the Revolving Loan Commitments exceeds (ii) the
aggregate outstanding principal amount of the Revolving Loan plus the Letter of
Credit Exposure.  The unused commitment fee shall be due and payable in arrears
on the last day of each calendar quarter and on the Revolving Loan Maturity
Date.

                 (b)      Fees for Letters of Credit.  For each Letter of
Credit issued by the Issuing Bank, the Borrower shall pay to the Agent for the
ratable benefit of the Banks a letter of credit fee equal to the Applicable
Margin for letter of credit fees per annum on the face amount of such Letter of
Credit for the stated term of such Letter of Credit, with a minimum fee of
$500.  In addition, for each Letter of Credit issued by the Issuing Bank, the
Borrower shall pay to the Agent for the benefit of the Issuing Bank a fronting
fee of 0.125% per annum on the face amount of such Letter of Credit for the
stated term of such Letter of Credit, with a minimum fee of $500. The Borrower
shall pay each such letter of credit fee for each Letter of Credit quarterly in
arrears within ten days after when billed therefor by the Issuing Bank.

                 (c)      Agent Fee Letter.  The Borrower shall pay to the
parties specified therein the fees and other amounts payable under the Agent
Fee Letter.

                 (d)      Fee Letter.  The Borrower shall pay to the Banks the
upfront fee payable to each Bank under the Fee Letter, based upon such Bank's
commitment amount.

         2.5     Interest.

                 (a)      Election of Interest Rate Basis.  The Borrower may
select the interest rate basis for the Revolving Loan in accordance with the
terms of this Section 2.5(a):

                          (i)     Under the Revolving Loan Borrowing Request
provided to the Agent in connection with the making of each Revolving Loan
Borrowing, the Borrower shall select the





                                      -25-
<PAGE>   31
amount  and the Type of the Tranches, and for each LIBOR Tranche selected, any
permitted Interest Period for each such LIBOR Tranche, which will comprise such
Revolving Loan Borrowing, provided that (A) at no time shall there be more than
ten separate LIBOR Tranches outstanding and (B) each LIBOR Tranche must be in a
principal amount equal to or greater than $1,000,000 and be made in multiples
of $500,000, and the Prime Rate Tranche must be in a principal amount equal to
or greater than$1,000,000 and be made in multiples of $100,000.  Such interest
rate elections must be provided to the Agent in writing or by telecopy not
later than 1:00 p.m. (local time at the Applicable Lending Office of the Agent)
on the third Business Day before the date of any proposed Revolving Loan
Borrowing comprised of a LIBOR Tranche or 11:00 a.m. (local time at the
Applicable Lending Office of the Agent) on the same day of any proposed
Revolving Loan Borrowing which is a Prime Rate Borrowing.  The Agent shall
promptly forward copies of such interest rate elections to the Banks.  In the
case of any Revolving Loan Borrowing comprised of a LIBOR Tranche, upon
determination by the Agent, the Agent shall promptly notify the Borrower and
the Banks of the applicable interest rate for such Tranche.

                          (ii)    With respect to any Tranche, the Borrower may
continue or convert any portion of any LIBOR Tranche or the Prime Rate Tranche
to form new LIBOR Tranches or increase or decrease the amount of the Prime Rate
Tranche in accordance with this paragraph.  Each such continuation or
conversion shall be deemed to create a new LIBOR Tranche or increase or
decrease the amount of the Prime Rate Tranche, as applicable, for all purposes
of this Agreement.  Each such continuation or conversion shall be made pursuant
to a Continuation/Conversion Request given by the Borrower to the Agent in
writing or by telecopy not later than 1:00 p.m. (local time at the Applicable
Lending Office of the Agent) on the third Business Day before the date of the
proposed continuation or conversion.  Each Continuation/Conversion Request
shall be fully completed and shall specify the information required therein,
and shall be irrevocable and binding on the Borrower.  The Agent shall promptly
forward notice of the continuation or conversion to the Banks.  In the case of
any continuation or conversion into LIBOR Tranches, upon determination by the
Agent, the Agent shall notify the Borrower and the Banks of the applicable
interest rate.  Continuations and conversions of LIBOR Tranches shall be made
in integral multiples of $500,000, and continuations and conversions of  the
Prime Rate Tranche shall be made in integral multiples of $100,000.  No
continuation or conversion shall be permitted if such continuation or
conversion would cause the aggregate outstanding principal amount of any LIBOR
Tranche which would remain outstanding to be less than $1,000,000, or the
aggregate outstanding principal amount of the Prime Rate Tranche which would
remain outstanding to be less than $1,000,000.  At no time shall there be more
than ten separate LIBOR Tranches outstanding.  Any conversion of an existing
LIBOR Tranche is subject to Section 2.5.  Subject to the satisfaction of all
applicable conditions precedent, the Agent and the Banks shall before close of
business on the date requested by the Borrower for the continuation or
conversion, make such continuation or conversion.

                          (iii)   At the end of the Interest Period for any
LIBOR Tranche if the Borrower has not continued or converted such LIBOR Tranche
into  new Tranches as provided for in paragraph (ii) above, the Borrower shall
be deemed to have continued such LIBOR Tranche as





                                      -26-
<PAGE>   32
a new LIBOR Tranche with an Interest Period of one month.  All of the Prime
Rate Tranche shall continue as the Prime Rate Tranche unless the Borrower
converts such Prime Rate Tranche as provided for in paragraph (ii) above.

                 (b)      LIBOR Tranches.  Each LIBOR Tranche shall bear
interest during its Interest Period at a per annum interest rate equal to the
sum of the LIBOR for such Tranche plus the Applicable Margin for LIBOR Tranches
in effect from time to time.  The Borrower shall pay to the Agent for the
ratable benefit of the Banks all accrued but unpaid interest on each LIBOR
Tranche on the last day of the applicable Interest Period for such LIBOR
Tranche (and with respect to LIBOR Tranches with Interest Periods of greater
than three months, on the date which is three months after the first date of
the Interest Period for such LIBOR Tranche), when required upon prepayment as
specified elsewhere in this Agreement, on any date when such LIBOR Tranche is
prepaid in full, and on the Revolving Loan Maturity Date.

                 (c)      Prime Rate Tranche.  The Prime Rate Tranche shall
bear interest at a per annum interest rate equal to the Base Rate in effect
from time to time plus the Applicable Margin for the Prime Rate Tranche in
effect from time to time.  The Borrower shall pay to the Agent for the ratable
benefit of the Banks all accrued but unpaid interest on the aggregate
outstanding principal amount of the Prime Rate Tranche on the last day of each
calendar quarter, when required upon prepayment as specified elsewhere in this
Agreement, on any date the Prime Rate Tranche is prepaid in full, and on the
Revolving Loan Maturity Date.

                 (d)      Usury Protection.

                          (i)     If, with respect to any Bank and the
Borrower, the effective rate of interest contracted for by such Bank with the
Borrower under the Credit Documents, including the stated rates of interest
contracted for hereunder and any other amounts contracted for under the Credit
Documents which are deemed to be interest, at any time exceeds the Highest
Lawful Rate, then the outstanding principal amount of the loans made by such
Bank to the Borrower hereunder shall bear interest at a rate which would make
the effective rate of interest on the loans made by such Bank to the Borrower
under the Credit Documents equal the Highest Lawful Rate until the difference
between the amounts which would have been due by the Borrower to such Bank at
the stated rates and the amounts which were due by the Borrower to such Bank at
the Highest Lawful Rate (the "Lost Interest") has been recaptured by such Bank.
If, when the loans made hereunder are repaid in full, the Lost Interest has not
been fully recaptured by such Bank pursuant to the preceding paragraph, then,
to the extent permitted by law, the interest rates charged by such Bank to the
Borrower hereunder shall be retroactively increased such that the effective
rate of interest on the loans made by such Bank to the Borrower under the
Credit Documents was at the Highest Lawful Rate since the effectiveness of this
Agreement to the extent necessary to recapture the Lost Interest not recaptured
pursuant to the preceding sentence and, to the extent allowed by law, the
Borrower shall pay to such Bank the amount of the Lost Interest remaining to be
recaptured by such Bank.





                                      -27-
<PAGE>   33
                          (ii)    In calculating all sums paid or agreed to be
paid to any Bank by the Borrower for the use, forbearance, or detention of
money under the Credit Documents, such amounts shall, to the extent permitted
by applicable law, be amortized, prorated, allocated, and spread in equal parts
throughout the term of the Credit Documents.

                          (iii)   NOTWITHSTANDING THE FOREGOING OR ANY OTHER
TERM IN THIS AGREEMENT AND THE CREDIT DOCUMENTS TO THE CONTRARY, it is the
intention of each Bank and the Borrower to conform strictly to any applicable
usury laws.  Accordingly, if any Bank contracts for, charges, or receives any
consideration from the Borrower which constitutes interest in excess of the
Highest Lawful Rate, then any such excess shall be canceled automatically and,
if previously paid, shall at such Bank's option be applied to the outstanding
amount of the loans made hereunder by such Bank to the Borrower or be refunded
to the Borrower.

         2.6     Breakage Costs.  If (i) any payment of principal on or any
conversion of any LIBOR Tranche is made on any date other than the last day of
the Interest Period for such LIBOR Tranche, whether as a result of any
voluntary or mandatory prepayment (other than a prepayment upon the occurrence
of any event subject to Section 2.8 or 2.9), any acceleration of maturity, or
any other cause, (ii) any payment of principal on any LIBOR Tranche is not made
when due, or (iii) any LIBOR Tranche is not borrowed, converted, or prepaid in
accordance with the respective notice thereof provided by the Borrower to the
Agent, whether as a result of any failure to meet any applicable conditions
precedent for borrowing, conversion, or prepayment, the permitted cancellation
of any request for borrowing, conversion, or prepayment, the failure of the
Borrower to provide the respective notice of borrowing, conversion, or
prepayment, or any other cause not specified above which is created by the
Borrower, then the Borrower shall pay to each Bank upon demand any amounts
required to compensate such Bank for any losses, costs, or expenses, including
lost profits and administrative expenses, which are reasonably allocable to
such action, including losses, costs, and expenses related to the liquidation
or redeployment of funds acquired or designated by such Bank to fund or
maintain such Bank's ratable share of such LIBOR Tranche or related to the
reacquisition or redesignation of funds by such Bank to fund or maintain such
Bank's ratable share of such LIBOR Tranche following any liquidation or
redeployment of such funds caused by such action.  Such Bank need not prove
matched funding of any particular funds, and a certificate as to the amount of
such loss, cost, or expense detailing the calculation thereof and certifying
that such Bank customarily charges such amounts to its other customers in
similar circumstances submitted by such Bank to the Borrower shall be
conclusive and binding for all purposes, absent manifest error.

         2.7     Increased Costs.

                 (a)      Cost of Funds.  If due to either (i) any introduction
of, change in, or change in the interpretation of any law or regulation, in
each case, after the date of this Agreement or (ii) compliance with any
guideline or request from any central bank or other governmental authority
having appropriate jurisdiction (whether or not having the force of law) given
after the date of this





                                      -28-
<PAGE>   34
Agreement, there shall be any increase in the costs of any Bank attributable to
(x) committing to make any Revolving Loan Advance or obtaining funds for the
making, funding, or maintaining of such Bank's ratable share of any LIBOR
Tranche in the relevant interbank market or (y) committing to make Letters of
Credit or issuing, funding, or maintaining Letters of Credit (including any
increase in any applicable reserve requirement specified by the Federal Reserve
Board, including those for emergency, marginal, supplemental, or other
reserves), then the Borrower shall pay to such Bank upon demand any amounts
required to compensate such Bank for such increased costs, such amounts being
due and payable upon demand by such Bank.  A certificate as to the cause and
amount of such increased cost detailing the calculation of such cost  and
certifying that such Bank customarily charges such amounts to its other
customers in similar circumstances submitted by such Bank to the Borrower shall
be conclusive and binding for all purposes, absent manifest error.  No Bank may
make any claim for compensation under this Section 2.7(a) for increased costs
incurred before 90 days prior to the delivery of any such certificate.

                 (b)      Capital Adequacy.  If, due to either (i) any
introduction of, change in, or change in the interpretation of any law or
regulation, in each case, after the date of this Agreement or (ii) compliance
with any guideline or request from any central bank or other governmental
authority having appropriate jurisdiction (whether or not having the force of
law) given after the date of this Agreement, there shall be any increase in the
capital requirements of any Bank or its parent or holding company attributable
to (x) committing to make Revolving Loan Advances or making, funding, or
maintaining Revolving Loan Advances or (y) committing to make Letters of Credit
or issuing, funding, or maintaining Letters of Credit, as such capital
requirements are allocated by such Bank, then the Borrower shall pay to such
Bank upon demand any amounts required to compensate such Bank or its parent or
holding company for such increase in costs (including an amount equal to any
reduction in the rate of return on assets or equity of such Bank or its parent
or holding company), such amounts being due and payable upon demand by such
Bank.  A certificate as to the cause and amounts detailing the calculation of
such amounts  and certifying that such Bank customarily charges such amounts to
its other customers in similar circumstances submitted by such Bank to the
Borrower shall be conclusive and binding for all purposes, absent manifest
error.  No Bank may make any claim for compensation under this Section 2.7(b)
for increased costs incurred before 90 days prior to the delivery of any such
certificate.

         2.8     Illegality.  Notwithstanding any other provision in this
Agreement, if it becomes unlawful for any Bank to obtain deposits or other
funds for making or funding such Bank's ratable share of any LIBOR Tranche in
the relevant interbank market, such Bank shall so notify the Borrower and the
Agent and such Bank's commitment to create LIBOR Tranches shall be suspended
until such condition has passed, all LIBOR Tranches applicable to such Bank
shall be converted to the Prime Rate Tranche as of the end of each applicable
Interest Period or earlier if necessary, and all subsequent requests for LIBOR
Tranches shall be deemed to be requests for Prime Rate Borrowings or
continuations and conversions of the Prime Rate Tranche, as applicable, with
respect to such Bank.





                                      -29-
<PAGE>   35
         2.9     Market Failure.  Notwithstanding any other provision in this
Agreement, if the Agent determines that: (a) quotations of interest rates for
the relevant deposits referred to in the definition of "LIBOR" are not being
provided in the relevant amounts, or maturities for purposes of determining the
rate of interest referred to in the definition of "LIBOR" or (b) the relevant
rates of interest referred to in the definition of "LIBOR" which are used as
the basis to determine the rate of interest for LIBOR Tranches will not
adequately cover the cost to any Bank of making or maintaining such Bank's
ratable share of any LIBOR Tranche, then if the Agent so notifies the Borrower,
the Agent and the Banks' commitment to create LIBOR Tranches shall be suspended
until such condition has passed, all LIBOR Tranches shall be converted to the
Prime Rate Tranche as of the end of each applicable Interest Period or earlier
if necessary, and all subsequent requests for LIBOR Tranches shall be deemed to
be requests for Prime Rate Borrowings or continuations and conversions of the
Prime Rate Tranche, as applicable, with respect to such Bank.

         2.10    Payment Procedures and Computations.

                 (a)      Payment Procedures.  Time is of the essence in this
Agreement and the Credit Documents.  All payment hereunder shall be made in
Dollars.  The Borrower shall make each payment under this Agreement and under
the Revolving Loan Notes not later than 12:00 noon (local time at the
Applicable Lending Office of the Agent) on the day when due to the Agent at the
Agent's Applicable Lending Office in immediately available funds.  All payments
by the Borrower hereunder shall be made without any offset, abatement,
withholding, deduction, counterclaim, or reduction.  Upon receipt of payment
from the Borrower of any principal, interest, or fees due to the Banks, the
Agent shall promptly after receipt thereof distribute to the Banks their
ratable share of such payments for the account of their respective Applicable
Lending Offices.  If and to the extent that the Agent shall not have so
distributed to any Bank its ratable share of such payments, the Agent agrees
that it shall pay interest on such amount for each day after the day when such
amount is made available to the Agent by the Borrower until the date such
amount is paid to such Bank by the Agent at the Federal Funds Rate in effect
from time to time, provided that if such amount is not paid by the Agent by the
end of the third day after the Borrower makes such amount available to the
Agent, the interest rates specified above shall be increased by a per annum
amount equal to 2.00% on the fourth day and shall remain at such increased rate
thereafter.  Interest on such amount shall be due and payable by the Agent upon
demand by such Bank.  Upon receipt of other amounts due solely to the Agent,
the Issuing Bank, the Swing Line Lender, or a specific Bank, the Agent shall
distribute such amounts to the appropriate party to be applied in accordance
with the terms of this Agreement.

                 (b)      Agent Reliance.  Unless the Agent shall have received
written notice from the Borrower prior to any date on which any payment is due
to the Banks that the Borrower shall not make such payment in full, the Agent
may assume that the Borrower has made such payment in full to the Agent on such
date and the Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such date an amount equal to the amount then due
such Bank.  If and to the extent the Borrower shall not have so made such
payment in full to the Agent, each Bank shall repay to the Agent forthwith on
demand such amount distributed to such Bank, together with interest





                                      -30-
<PAGE>   36
thereon from the date such amount is distributed to such Bank until the date
such Bank repays such amount to the Agent, at an interest rate equal to, the
Federal Funds Rate in effect from time to time, provided that with respect to
such Bank, if such amount is not repaid by such Bank by the end of the second
day after the date of the Agent's demand, the interest rates specified above
shall be increased by a per annum amount equal to 2.00% on the third day after
the date of the Agent's demand and shall remain at such increased rate
thereafter.

                 (c)      Sharing of Payments.  Each Bank agrees that if it
should receive any payment (whether by voluntary payment, by realization upon
security, by the exercise of the right of setoff or banker's lien, by
counterclaim or cross action, by the enforcement of any right under the Credit
Documents, or otherwise) in respect of any obligation of the Borrower to pay
principal, interest, fees, or any other obligation incurred under the Credit
Documents in a proportion greater than the total amount of such principal,
interest, fees, or other obligation then owed and due by the Borrower to such
Bank bears to the total amount of principal, interest, fees, or other
obligation then owed and due by the Borrower to all of the Banks immediately
prior to such receipt, then such Bank receiving such excess payment shall
purchase for cash without recourse from the other Banks an interest in the
obligations of the Borrower to such Banks in such amount as shall result in a
participation by all of the Banks, in proportion with the Banks' respective pro
rata shares, in the aggregate unpaid amount of principal, interest, fees, or
any such other obligation, as the case may be, owed by the Borrower to all of
the Banks; provided that if all or any portion of such excess payment is
thereafter recovered from such Bank, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, in proportion with the
Banks' respective pro rata shares, but without interest.

                 (d)      Authority to Charge Accounts.  The Agent, if and to
the extent payment owed to the Agent or any Bank is not made when due, may
charge from time to time against any account of the Borrower with the Agent any
amount so due.  The Agent agrees promptly to notify the Borrower after any such
charge and application made by the Agent provided that the failure to give such
notice shall not affect the validity of such charge and application.

                 (e)      Interest and Fees.  Unless expressly provided for in
this Agreement, (i) all computations of interest based on the Prime Rate
(including the Base Rate, when applicable) shall be made on the basis of a
365/366 day year, as the case may be, (ii) all computations of interest based
on the Federal Funds Rate (including the Base Rate, when applicable) shall be
made on the basis of a 360 day year, (iii) all computations of interest based
upon the LIBOR shall be made on the basis of a 360 day year, and (iv) all
computations of fees shall be made on the basis of a 360 day year, in each case
for the actual number of days (including the first day, but excluding the last
day) occurring in the period for which such interest or fees are payable.  Each
determination by the Agent of an interest rate or fee shall be conclusive and
binding for all purposes, absent manifest error.

                 (f)      Payment Dates.  Whenever any payment shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or





                                      -31-
<PAGE>   37
fees, as the case may be.  If the time for payment for an amount payable is not
specified in this Agreement or in any other Credit Document, the payment shall
be due and payable on demand by the Agent or the applicable Bank.

         2.11    Taxes.

                 (a)      No Deduction for Certain Taxes.  Any and all payments
by the Borrower shall be made free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges, or
withholdings, and all liabilities with respect thereto, other than taxes
imposed on the income and franchise taxes imposed on the Agent, any Bank, or
the Applicable Lending Office thereof by any jurisdiction in which any such
entity is a citizen or resident or any political subdivision of such
jurisdiction (all such nonexcluded taxes, levies, imposts, deductions, charges,
withholdings, and liabilities being hereinafter referred to as "Taxes").  If
the Borrower shall be required by law to deduct any Taxes from or in respect of
any sum payable to the Agent, any Bank, or the Applicable Lending Office
thereof, (i) the sum payable shall be increased as may be necessary so that,
after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.11), such Person receives an
amount equal to the sum it would have received had no such deductions been
made; (ii) the Borrower shall make such deductions; and (iii) the Borrower
shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

                 (b)      Other Taxes.  The Borrower agrees to pay any present
or future stamp or documentary taxes or any other excise or property taxes,
charges, or similar levies which arise from any payment made or from the
execution, delivery, or registration of, or otherwise with respect to, this
Agreement or the other Credit Documents (other than those which become due as a
result of any Bank joining this Agreement as a result of any Assignment and
Acceptance, which shall be paid by the Bank which becomes a Bank hereunder as a
result of such Assignment and Acceptance).

                 (c)      Foreign Bank Withholding Exemption.  Each Bank and
Issuing Bank that is not incorporated under the laws of the United States of
America or a state thereof agrees that it shall deliver to the Borrower and the
Agent (i) two duly completed copies of United States Internal Revenue Service
Form 1001 or 4224 or successor applicable form, as the case may be, certifying
in each case that such Bank is entitled to receive payments under this
Agreement and the Revolving Loan Notes payable to it, without deduction or
withholding of any United States federal income taxes, (ii) if applicable, an
Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the
case may be, to establish an exemption from United States backup withholding
tax, and (iii) any other governmental forms which are necessary or required
under an applicable tax treaty or otherwise by law to reduce or eliminate any
withholding tax, which have been reasonably requested by the Borrower.  Each
Bank which delivers to the Borrower and the Agent a Form 1001 or 4224 and Form
W-8 or W-9 pursuant to the next preceding sentence further undertakes to
deliver to the Borrower and the Agent two further copies of the said letter and
Form 1001 or 4224 and Form W-8 or W-9, or successor applicable forms, or other
manner of certification, as the case may be, on or





                                      -32-
<PAGE>   38
before the date that any such letter or form expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent letter
and form previously delivered by it to the Borrower and the Agent, and such
extensions or renewals thereof as may reasonably be requested by the Borrower
and the Agent certifying in the case of a Form 1001 or 4224 that such Bank is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes.  If an event (including
without limitation any change in treaty, law or regulation) has occurred prior
to the date on which any delivery required by the preceding sentence would
otherwise be required which renders all such forms inapplicable or which would
prevent any Bank from duly completing and delivering any such letter or form
with respect to it and such Bank advises the Borrower and the Agent that it is
not capable of receiving payments without any deduction or withholding of
United States federal income tax, and in the case of a Form W-8 or W-9,
establishing an exemption from United States backup withholding tax, such Bank
shall not be required to deliver such letter or forms.  The Borrower shall
withhold tax at the rate and in the manner required by the laws of the United
States with respect to payments made to a Bank failing to provide the requisite
Internal Revenue Service forms in a timely manner.  Each Bank which fails to
provide to the Borrower in a timely manner such forms shall reimburse the
Borrower upon demand for any penalties paid by the Borrower as a result of any
failure of the Borrower to withhold the required amounts that are caused by
such Bank's failure to provide the required forms in a timely manner.

         2.12    Change of Lending Office.

         (a)     Each Bank agrees that if it makes any demand for payment under
Section 2.7 or 2.11(a), or if any adoption or change of the type described in
Section 2.8 shall occur with respect to it, it will use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions and
so long as such efforts would not be disadvantageous to it, as determined in
its sole discretion) to designate a different lending office if the making of
such a designation would reduce or obviate the need for the Borrower to make
payments under Section 2.7 or 2.11(a), or would eliminate or reduce the effect
of any adoption or change described in Section 2.8.

         (b)     If any Bank (including any participant Bank under Section 8.5)
shall assert that any adoption or change of the type described in Section 2.8
hereof has occurred with respect to it, or if any Bank (including any
participant Bank under Section 8.5) requests compensation under Section 2.7, or
if the Borrower is required to pay any additional amount to any Bank or any
authority for the account of any Bank pursuant to Section 2.11, then the
Borrower may, at its expense and effort, upon notice to such Bank and the
Agent, require such Bank to, and such Bank promptly shall, assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in Section 8.5), all its interests, rights, and obligations under this
Agreement to an assignee that shall assume such obligations (which assignee may
be another Bank, if a Bank accepts such assignment); provided that (i) if such
assignee is not a Bank or an Affiliate thereof, the Borrower shall have
received the prior written consent of the Agent and the Issuing Bank which
consents shall not unreasonably be withheld or delayed, (ii) such Bank shall
have received payment of an amount equal to the aggregate





                                      -33-
<PAGE>   39
outstanding principal of such Bank's Revolving Loan Advances and its
participations in Letters of Credit, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder, from the assignee (at least to the
extent of such outstanding principal) and the Borrower (in the case of all
other amounts), and (iii) in the case of any such assignment resulting from a
claim for compensation under Section 2.7 or payment required to be made
pursuant to Section 2.11, such assignment will result in a reduction in such
compensation or payments compared to the compensation or payments payable to
the assigning Bank.  A Bank shall not be required to make any such assignment
and delegation if, prior thereto, as a result of a waiver by such Bank or
otherwise, the circumstances entitling the Borrower to require such assignment
and delegation no longer exist or cease to apply.

ARTICLE 3.       CONDITIONS PRECEDENT.

         3.1     Conditions Precedent to Initial Extension of Credit.  The

representation, and additional warranty of the representations and warranties
contained in each Credit Document as of such date); and

                 (b)      Default.  As of the date of the making of any
extension of credit hereunder, there shall exist no Default or Event of

under the laws of such Person's respective jurisdiction of organization and (b)

         4.2     Authorization.  The execution, delivery, and performance by
each Credit Party of the Credit Documents to which such Credit Party is a party
and the consummation of the transactions contemplated thereby (a) do not

Credit Party in accordance with such Credit Document's terms, except as limited
by applicable bankruptcy, insolvency, reorganization, moratorium, or similar
laws at the time in effect affecting the rights of creditors generally and
subject to the availability of equitable remedies.

         4.4     Absence of Conflicts and Approvals.   The execution, delivery,
and performance by each Credit Party of the Credit Documents to which such

         4.7     Financial Condition.

                 (a)      The Borrower has delivered to the Agent the
Registration Statement, including therein the proforma combined balance sheet
of the Borrower following the public offering of securities contemplated
therein and proforma combined statement of income for the periods shown
therein, which accurately and completely, in all material respects, present
fairly the financial condition of Borrower as of such date.  The Borrower has
delivered to the Agent the Interim Financial Statements, and the Interim
Financial Statements are accurate and complete in all material respects and
present fairly the financial condition of Borrower as of their date and for
their period in accordance with generally accepted accounting principles, as
applicable to interim financial reports.

                 (b)      As of the date of the Registration Statement and the
Interim Financial Statements, there were no material contingent obligations,
liabilities for taxes, unusual forward or long-term commitments, or unrealized
or anticipated losses of the Borrower or any of the Borrower's Subsidiaries,
except as disclosed in the Registration Statement and the Interim Financial
Statements, and adequate reserves for such items have been made in accordance
with generally accepted accounting principles.  No Material Adverse Change has
occurred since the date of the Registration Statement or the Interim Financial
Statements.  No Default exists.

         4.8     Condition of Assets.  Each Restricted Entity has good and
indefeasible title to substantially all of its owned property and valid
leasehold rights in all of its leased property, as reflected in the financial
statements most recently provided to the Agent free and clear of all Liens
except Permitted Liens.  Each Restricted Entity possesses and has properly
approved, recorded, and filed, where applicable, all permits, licenses,
patents, patent rights or licenses, trademarks, trademark rights, trade names
rights, and copyrights which are useful in the conduct of its business and
which the failure to possess could reasonably be expected to cause a Material
Adverse Change.  The material properties used in the operations of each
Restricted Entity are in good repair, working order, and condition, normal wear
and tear excepted.  The properties of each Restricted Entity have not been
adversely affected as a result of any fire, explosion, earthquake, flood,
drought, windstorm, accident, strike or other labor disturbance, embargo,
requisition or taking of property or cancellation of contracts, permits, or
concessions by a governmental authority, riot, activities of armed forces, or
acts of God or of any public enemy in any manner which (after giving effect to
any insurance proceeds) could reasonably be expected to cause a Material
Adverse Change.

         4.9     Litigation.  There are no actions, suits, or proceedings
pending or, to the knowledge of the Borrower, threatened against any Restricted
Entity at law, in equity, or in admiralty, or by or before any governmental

foreign, or any arbitrator which could reasonably be expected to cause a
Material Adverse Change.

         4.10    Subsidiaries.  As of the date of this Agreement, the Borrower
has no Subsidiaries except as disclosed in Schedule II.  The Borrower has no
Subsidiaries which have not been disclosed in writing to the Agent.

         4.11    Laws and Regulations.  Each Restricted Entity is in compliance
with all federal, state, and local laws and regulations which are applicable to
the operations and property of such Person where the failure to comply with the
same could reasonably be expected to cause a Material Adverse Change.

         4.12    Environmental Compliance.  Each Restricted Entity has been and
is in compliance with all Environmental Laws and has obtained and is in
compliance with all related permits necessary for the ownership and operation
of any such Person's properties, in each case, where the failure to be in
compliance with the same could reasonably be expected to cause a Material
Adverse Change.  Each Restricted Entity has not received notice of and has not
been investigated for any violation or alleged violation of any Environmental
Law in connection with any such Person's presently or previously owned
properties which currently threaten action or suggest liabilities which could
reasonably be expected to cause a Material Adverse Change.  Each Restricted
Entity does not and has not created, handled, transported, used, or disposed of
any Hazardous Materials on or about any such Person's properties (nor has any
such Person's properties been used for those purposes); has never been
responsible for the release of any Hazardous Materials into the environment in
connection with any such Person's operations and has not contaminated any
properties with Hazardous Materials; and does not and has not owned any
properties contaminated by any Hazardous Materials, in each case in any manner
which could reasonably be expected to cause a Material Adverse Change.

         4.13    ERISA.  Each Restricted Entity and each of their respective
Commonly Controlled Entities are in compliance with all provisions of ERISA to
the extent that the failure to be in compliance could reasonably be expected to
cause a Material Adverse Change.  No Restricted Entity nor any of their
respective Commonly Controlled Entities participates in or during the past five
years has participated in any employee pension benefit plan covered by Title IV
of ERISA or any multiemployer plan under Section 4001(a)(3) of ERISA.  With
respect to the Plans of the Restricted Entities, no Material Reportable Event
or Prohibited Transaction has occurred and exists that could reasonably be
expected to cause a Material Adverse Change.

         4.14    Taxes.  Each Restricted Entity has filed all United States
federal, state, and local income tax returns and all other domestic and foreign
tax returns which are required to be filed by such Person and has paid, or
provided for the payment before the same became delinquent of, all taxes due
pursuant to such returns or pursuant to any assessment received by such Person
except for tax payments being contested in good faith, for which adequate
reserves have been established and reported in accordance with general accepted
accounting principals, and which could not reasonably be expected to cause a
Material Adverse Change.  The charges, accruals, and reserves on the books





                                      -37-
<PAGE>   43
of the Restricted Entities in respect of taxes are adequate in accordance with
generally accepted accounting principles.

         4.15    True and Complete Disclosure.  All factual information
furnished by or on behalf of any Credit Party in writing to the Agent or any
Bank in connection with the Credit Documents and the transactions contemplated
thereby is true and accurate in all material respects on the date as of which
such information was dated or certified and does not contain any untrue
statement of material fact or omit to state any material fact necessary to make
the statements contained therein not misleading.  All projections, estimates,
and pro forma financial information furnished by any Credit Party were prepared
on the basis of assumptions, data, information, tests, or conditions believed
to be reasonable at the time such projections, estimates, and pro forma
financial information were furnished.

         4.16    Year 2000.

                 (a)      Except to the extent that a failure to do so could
not reasonably be expected to cause a Material Adverse Change, the Borrower (i)
has begun analyzing the operations of the Restricted Entities that could be
adversely affected by failure to become Year 2000 compliant (that is, that
computer applications, imbedded microchips and other systems will be able to
perform date-sensitive functions prior to and after December 31, 1999); and
(ii) is developing a plan for becoming Year 2000 compliant in a timely manner.
The Borrower reasonably believes that it will become Year 2000 compliant for
its operations and those of its Subsidiaries and Affiliates on a timely basis
except to the extent that a failure to do so could not reasonably be expected
to cause a Material Adverse Change.

                 (b)      The Borrower will promptly notify the Bank in the
event the Borrower determines that any computer application which is material
to the operations of the Borrower, its Subsidiaries, or its Affiliates or any
of its material vendors or suppliers will not be fully Year 2000 compliant on a
timely basis, except to the extent that such failure could not reasonably be
expected to cause a Material Adverse Change.

other Credit Document, the Borrower shall comply with and cause compliance with
the following covenants:

<PAGE>   46
reasonably requested, provided that the Borrower is given at least 3 Business

provided further that so long as no Default or Event of Default exists, the
Agent and the Banks shall not exercise the foregoing inspection right more

         5.4     Use of Proceeds.  The proceeds of the Revolving Loan
Borrowings shall be used by the Borrower for Acquisitions, working capital

the Board of Governors of the Federal Reserve System.

         5.5     Financial Covenants.  The Agent shall determine compliance
with the following financial covenants based upon the applicable Schedule of
the most recent Compliance Certificate delivered to the Agent pursuant to
Section 5.2(a) or 5.2(b).

                 (a)      Net Worth.  The Borrower shall not permit the
consolidated Net Worth of the Borrower as of the last day of each fiscal
quarter to be less than the sum of (i) $187,500,000, plus (ii) 90% of the
cumulative quarterly consolidated net income of the Borrower after March 31,
1998, for each fiscal quarter of the Borrower during which the Borrower has
positive consolidated net earnings; plus (iii) 100% of the net proceeds
received by Borrower after March 31, 1998, from any sale or issuance of any
equity securities of, or any other additions to capital by, the Borrower or its

under this Section 5.5(a) was not increased in clauses (i) through (iii) above

Worth of the Borrower resulting from any Acquisition.  Compliance with this
paragraph (a) shall be determined based upon Schedule C of the applicable
Compliance Certificate.

                 (b)      Maximum Debt to EBITDA Ratio.  As of the last day of
each fiscal quarter of the Borrower, the Borrower shall not permit the ratio of
(i) the consolidated Debt of the Borrower as of end of such fiscal quarter to
(ii) the consolidated EBITDA of the Borrower for the preceding four fiscal
quarters then ended, to be greater than 2.50 to 1.00.  Compliance with this
paragraph (b) shall be determined based upon Schedule C of the applicable
Compliance Certificate.

                 (c)      Minimum Fixed Charge Coverage Ratio.  As of the last
day of each fiscal quarter, the Borrower shall not permit the ratio of (i) the
consolidated EBITDA of the Borrower for the preceding four fiscal quarters then

(ii) (A) the consolidated Interest Expense of the Borrower for the preceding
four fiscal quarters then ended plus (B) the aggregate amount of Restricted
Payments declared or paid by the Borrower during such period plus (C) the
consolidated Capital Expenditures (other than Capital Expenditures that are
deemed to occur solely because of the making of an Acquisition) of the Borrower
during such period plus (D) the consolidated current maturities of the Borrower





                                      -41-

amount of the Revolving Loan as of the last day of such fiscal quarter or (2)
$4,000,000, to be less than 1.75 to 1.00; provided, that with respect to a
determination for which any component of such determination involves Persons
which were not Restricted Entities for the entire applicable period of
determination, the Cash Taxes paid by each such Person during such period may,
at the election of the Borrower, be deemed to be equal to the product of (a)
the EBITDA of such Person for the applicable period multiplied by (b) 39%.
Compliance with this paragraph (c) shall be determined based upon Schedule C of
the applicable Compliance Certificate.

                 (d)      Capital Expenditures. The Borrower shall not permit
the consolidated Capital Expenditures (other than Capital Expenditures that are
deemed to occur because of the making of an Acquisition) of the Borrower during
any four quarter period to exceed an amount equal to 6% of the consolidated Net
Worth of the Borrower as of the end of the applicable four quarter period;
provided, that with respect to a determination including any fiscal quarter
which involves Persons which were not Restricted Entities for the entire
applicable period of determination, the Capital Expenditures of each such
Person for each such quarterly period shall be deemed to be equal to the
quotient of (i) the consolidated Capital Expenditures of such Person for the
fiscal year then most recently ended, divided by (ii) 4.  Compliance with this
paragraph (d) shall be determined based upon Schedule C of the applicable
Compliance Certificate.

         5.6     Debt.

                 (a)      The Borrower shall not permit any Restricted Entity

Permitted Debt.

                 (b)      The Borrower shall, as soon as available but in any
event not less than 10 Business Days prior to the issuance of any preferred
stock or subordinated indebtedness, deliver to the Agent a copy of the
certificate of designation or subordinated debt documents, as applicable,
together with a certificate, signed by a Responsible Officer of the Borrower,
certifying that such preferred stock or subordinated indebtedness constitutes
Qualified Preferred Stock or Subordinated Debt pursuant to the terms of this
Agreement.

         5.7     Liens.  The Borrower shall not permit any Restricted Entity to

to create, incur, assume, or suffer to exist any obligations in respect of

Restricted Entity of the underlying commodity for the relevant period, but no
Derivatives which are speculative in nature.

         5.9     Corporate Transactions. The Borrower shall not, without the
Agent's consent, permit any Restricted Entity to (a) merge, consolidate, or
amalgamate with another Person, or liquidate, wind up, or dissolve itself  (or
take any action towards any of the foregoing), (b) convey, sell, lease, assign,
transfer, or otherwise dispose of any of its property, businesses, or other
assets outside of the ordinary course of business, or (c) make any Acquisition
except that:

                 (i)      Any Subsidiary of the Borrower may merge,
         consolidate, or amalgamate into the Borrower or any wholly owned
         Subsidiary of the Borrower, or convey, sell, lease, assign, transfer,
         or otherwise dispose of any of its assets to the Borrower or any
         wholly-owned Subsidiary of the Borrower (and if such disposition
         transfers all or substantially all of the assets of transferring
         Subsidiary, such subsidiary may then liquidate, wind up, or dissolve
         itself); provided that the Borrower or the wholly-owned Subsidiary, as
         applicable, is the surviving or acquiring entity; and

                 (ii)     The Borrower or any Subsidiary of the Borrower may
         make any Acquisition (by purchase or merger) provided that (A) the
         Borrower or such Subsidiary of the Borrower is the acquiring or
         surviving entity, (B) the aggregate of all consideration (other than
         common stock of the Borrower) paid by the Restricted Entities in

         Majority Banks, (C) the aggregate of all consideration (other than
         common stock of the Borrower) paid by the Restricted Entities in
         connection with all Acquisitions during any calendar year (exclusive
         of any such consideration paid prior to the date of this Agreement)
         does not exceed $30,000,000 without the prior consent of the Majority
         Banks, (D) no Default or Event of Default exists and the Acquisition
         would not reasonably be expected to cause a Default or Event of
         Default (including any default under Section 5.5 with respect to
         historical and future proforma financial status and results), and (E)
         the acquired assets are in substantially the same business as the
         Borrower; provided that to the extent that the Borrower obtains the
         consent of the Majority Banks to an Acquisition pursuant to
         subsections (B) or (C) above, the consideration paid by the Restricted
         Entities in connection with such Acquisition shall not be included in
         the calculations of the limitations contained in such subsections.

         5.10    Distributions.  The Borrower shall not (a) declare or pay any
dividends; (b) purchase, redeem, retire, or otherwise acquire for value any of
its capital stock now or hereafter outstanding; or make any distribution of

of it; (c) allocate or otherwise set apart any sum for the payment of any
dividend or





                                      -43-

distribution on, or for the purchase, redemption, or retirement of, any shares
of its capital stock; or (d) make any other distribution by reduction of
capital or otherwise in respect of any shares of its capital stock, except that
the Borrower may make payments of dividends on Qualified Preferred Stock.

         5.11    Transactions with Affiliates.  The Borrower shall not permit
any Restricted Entity to enter into any transaction directly or indirectly with
or for the benefit of an Affiliate except transactions with an Affiliate for
the leasing of property, the rendering or receipt of services, or the purchase
or sale of inventory or other assets in the ordinary course of business if the
monetary or business consideration arising from such a transaction would be
substantially as advantageous to such Restricted Entity as the monetary or
business consideration which such Restricted Entity would obtain in a
comparable arm's length transaction.

         5.12    Insurance.

                 (a)      The Borrower shall cause each Restricted Entity to
maintain insurance with responsible and reputable insurance companies or
associations reasonably acceptable to the Agent in such amounts and covering
such risks as are usually carried by companies engaged in similar businesses
and owning similar properties in the same general areas in which such Persons
operate.  Without limiting the foregoing, the Borrower shall maintain insurance
coverage for the Restricted Entities equal to or better than, on an item by
item basis for each item, the coverage for the Restricted Entities existing on
the date of this Agreement.  The Borrower shall deliver to the Agent
certificates evidencing such policies or copies of such policies at the Agent's
request following a reasonable period to obtain such certificates taking into
account the jurisdiction where the insurance is maintained.

                 (b)      All policies representing liability insurance of the
Restricted Entities shall name the Agent and the Banks as additional named
insureds in a form satisfactory to the Agent. All proceeds of such liability
insurance coverage for the Agent and the Banks shall be paid as directed by the
Agent to indemnify the Agent or the applicable Bank for the liability covered.
In the event that proceeds of property or liability insurance are paid to any
Restricted Entity in violation of the foregoing, the Restricted Entity shall
hold the proceeds in trust for the Agent, segregate the proceeds from the other
funds of such Restricted Entity, and promptly pay the proceeds to the Agent
with any necessary endorsement.  The Agent shall have the right, but not the
obligation, during the existence of an Event of Default, to make proof of loss
under, settle and adjust any claim under, and receive the proceeds under the
insurance, and the reasonable expenses incurred by the Agent in the adjustment
and collection of such proceeds shall be paid by the Borrower.  The Borrower
irrevocably appoints the Agent as its attorney in fact to take such actions in
its name.  If the Agent does not take such actions, the Borrower may take such
actions subject to the approval of any final action by the Agent.  The Agent
shall not be liable or responsible for failure to collect or exercise diligence
in the collection of any proceeds.





                                      -44-

         5.13    Investments.  The Borrower shall not permit any Restricted
Entity to make or hold any direct or indirect investment in any Person,
including capital contributions to the Person, investments in the debt or
equity securities of the Person, and loans, guaranties, trade credit, or other
extensions of credit to the Person, except for Permitted Investments.

         5.14    Lines of Business.  The Borrower shall not permit the
Restricted Entities to change the character of their business as conducted on
the date of this Agreement, or engage in any type of business not reasonably
related to such business as presently and normally conducted.

         5.15    Compliance with Laws.  The Borrower shall cause each
Restricted Entity to comply with all federal, state, and local laws and
regulations which are applicable to the operations and property of such
Persons, in each case, where the failure to comply could reasonably be expected
to cause a Material Adverse Change.

         5.16    Environmental Compliance.  The Borrower shall cause each
Restricted Entity to comply with all Environmental Laws and obtain and comply
with all related permits necessary for the ownership and operation of any such
Person's properties, in each case, where the failure to comply could reasonably
be expected to cause a Material Adverse Change.  The Borrower shall cause each
Restricted Entity to promptly disclose to the Agent any notice to or
investigation of such Persons for any violation or alleged violation of any
Environmental Law in connection with any such Person's presently or previously
owned properties which represent liabilities which could reasonably be expected
to cause a Material Adverse Change.  The Borrower shall not permit any
Restricted Entity to create, handle, transport, use, or dispose of any
Hazardous Materials on or about any such Person's properties; release any
Hazardous Materials into the environment in connection with any such Person's
operations or contaminate any properties with Hazardous Materials; or own
properties contaminated by any Hazardous Materials, in each case in any manner
that could reasonably be expected to cause a Material Adverse Change.

         5.17    ERISA Compliance.  The Borrower shall cause each Restricted
Entity to (i) comply in all material respects with all applicable provisions of
ERISA and prevent the occurrence of any Reportable Event or Prohibited
Transaction with respect to, or the termination of, any of their respective
Plans, in each case, where the failure to do so could reasonably be expected to
cause a Material Adverse Change and (ii) not create or participate in any
employee pension benefit plan covered by Title IV of ERISA or any multiemployer
plan under Section 4001(a)(3) of ERISA.

         5.18    Payment of Certain Claims.  The Borrower shall cause each
Restricted Entity to pay and discharge, before the same shall become
delinquent, (a) all taxes, assessments, levies, and like charges imposed upon
any such Person or upon any such Person's income, profits, or property by
authorities having competent jurisdiction prior to the date on which penalties
attach thereto except for tax payments being contested in good faith for which
adequate reserves have been established  and reported in accordance with
generally accepted accounting principals which could not reasonably be expected
to cause a Material Adverse Change and (b) all trade payables and current
operating





                                      -45-
<PAGE>   51
liabilities, unless the same are less than 90 days past due or are being
contested in good faith, have adequate reserves established and reported in
accordance with general accepted accounting principals, and could not
reasonably be expected to cause a Material Adverse Change.

         5.19    Subsidiaries. Upon the formation or acquisition of any new
Subsidiary, the Borrower shall and shall cause such Subsidiary to promptly, but
in any event within 30 days after the formation or acquisition of such new
Subsidiary, execute and deliver to the Agent such guaranties, security
agreements, pledge agreements, amendment agreements, consents, and other
documents and agreements as the Agent requests so that such Subsidiary
guarantees and secures the Credit Obligations on the same terms as the existing
Subsidiaries of the Borrower (including the execution and delivery of a Joinder
Agreement in substantially the form of Exhibit G for the purpose of joining
such Subsidiary as a party to the Guaranty, the Security Agreement, and, if
applicable, the Stock Pledge Agreement or the Partnership Pledge Agreement, or
the execution of such new guaranties, pledge agreements, security agreements,
and consents as the Agent determines are necessary to have the same effect in
different jurisdictions).  In connection therewith and within 30 days after the
formation or acquisition of such new Subsidiary, the Borrower shall provide
corporate documentation and opinion letters reasonably satisfactory to the
Agent reflecting the corporate status of such new Subsidiary of the Borrower
and the enforceability of such agreements.

<PAGE>   52
                 (d)      Security and Support Documents.  Any Security

reasonable control of any Bank) cease to create the Lien on the property
purported to be subject to such agreement in accordance with the terms of such
agreement, or cease to be in full force and effect, or shall be contested by
any party thereto;

                 (e)      Guaranty.  (i) the Guaranty shall at any time and for

obligation thereunder, or (ii) any breach by any Guarantor of any of the
covenants contained in Section 1 of the Guaranty;

                 (f)      Material Debt Default.  (i) Any principal, interest,

of all Debt of such Persons so in default exceeds $250,000; (ii) any other
event shall occur or condition shall exist under any agreement or instrument
relating to any Debt of any such Person (other than the Credit Obligations) the

such event or condition shall not be cured within the applicable grace period,
if any, and the aggregate amount of all Debt of such Persons so in default

reasonably be expected to cause a Material Adverse Change and such breach is
not cured within the applicable grace period, if any;

                 (h)      Bankruptcy and Insolvency.  (i) there shall have been
filed against any Restricted Entity or any such Person's properties, without

benefit of creditors or other arrangement with creditors, or admits in writing
such Person's inability to pay such Person's debts as they become due (the
occurrence of any Event of Default under clause (i) or (ii) of this paragraph
being a "Bankruptcy Event of Default");





                                      -47-
<PAGE>   53
                 (h)      Adverse Judgment.  The aggregate outstanding amount

Control.

         6.2     Termination of Revolving Loan Commitments.  Upon the
occurrence of any Bankruptcy Event of Default, all of the commitments of the
Agent and the Banks hereunder shall terminate.  During the existence of any
Event of Default other than a Bankruptcy Event of Default, the Agent shall at
the request of the Majority Banks declare by written notice to the Borrower all
of the commitments of the Agent and the Banks hereunder terminated, whereupon
the same shall immediately terminate.

         6.3     Acceleration of Credit Obligations.  Upon the occurrence of
any Bankruptcy Event of Default, the aggregate outstanding principal amount of
all loans made hereunder, all accrued interest thereon, and all other Credit
Obligations shall immediately and automatically become due and payable.  During
the existence of any Event of Default other than a Bankruptcy Event of Default,
the Agent shall at the request of the Majority Banks declare by written notice
to the Borrower the aggregate outstanding principal amount of all loans made
hereunder, all accrued interest thereon, and all other Credit Obligations to be
immediately due and payable, whereupon the same shall immediately become due
and payable.  In connection with the foregoing, except for the notice provided
for above in this Article VI, the Borrower waives notice of any Default or
Event of Default, grace, notice of intent to accelerate, notice of
acceleration, presentment, demand, notice of nonpayment, protest, and all other
notices.

         6.4     Cash Collateralization of Letters of Credit.  Upon the
occurrence of any Bankruptcy Event of Default, the Borrower shall pay to the
Agent an amount equal to the Letter of Credit Exposure to be held in the Letter
of Credit Collateral Account for disposition in accordance with Section 2.2(g).
During the existence of any Event of Default other than a Bankruptcy Event of
Default, the Agent shall at the request of the Majority Banks require by
written notice to the Borrower that the Borrower pay to the Agent an amount
equal to the Letter of Credit Exposure to be held in the Letter of Credit
Collateral Account for disposition in accordance with Section 2.2(g), whereupon
the Borrower shall pay to the Agent such amount for such purpose.

         6.5     Default Interest.  If any Event of Default exists based upon a
default in the payment of any amounts owing hereunder, the Agent shall at the
request of the Majority Banks declare by written notice to the Borrower that
the Credit Obligations specified in such notice shall bear interest beginning
on the date specified in such notice until paid in full at the applicable
Default Rate for such Credit Obligations, whereupon the Borrower shall pay such
interest to the Agent for the benefit of the Agent and the Banks, as
applicable, upon demand by the Agent.  If any other Event of Default exists,
the Agent shall at the request of the Majority Banks declare by written notice
to the Borrower that, unless such Event of Default is cured to the satisfaction
of the Agent and the Majority Banks





                                      -48-
<PAGE>   54
on or before the 30th day following the occurrence of such Event of Default,
the Credit Obligations specified in such notice shall bear interest beginning
on such 30th day until paid in full at the applicable Default Rate for such
Credit Obligations, whereupon the Borrower shall, if such Event of Default is
not cured by such date, pay such interest to the Agent for the benefit of the
Agent and the Banks, as applicable, upon demand by the Agent after such date.

         6.6     Right of Setoff.  During the existence of an Event of Default,
the Agent and each Bank is hereby authorized at any time, to the fullest extent
permitted by law, to set off and apply any indebtedness owed by the Agent or
such Bank to the Borrower against any and all of the obligations of the
Borrower under this Agreement and the Credit Documents, irrespective of whether
or not the Agent or such Bank shall have made any demand under this Agreement
or the Credit Documents and although such obligations may be contingent and
unmatured.  The Agent and each Bank, as the case may be, agrees promptly to
notify the Borrower after any such setoff and application made by such party
provided that the failure to give such notice shall not affect the validity of
such setoff and application.

         6.7     Actions Under Credit Documents.  Following an Event of
Default, the Agent shall at the request of the Majority Banks take any and all
actions permitted under the other Credit Documents, including the Guaranty and
the Security Documents.

         6.8     Remedies Cumulative.  No right, power, or remedy conferred to
the Agent or the Banks in this Agreement and the Credit Documents, or now or
hereafter existing at law, in equity, by statute, or otherwise, shall be
exclusive, and each such right, power, or remedy shall to the full extent
permitted by law be cumulative and in addition to every other such right,
power, or remedy.  No course of dealing and no delay in exercising any right,
power, or remedy conferred to the Agent or the Banks in this Agreement and the
Credit Documents, or now or hereafter existing at law, in equity, by statute,
or otherwise, shall operate as a waiver of or otherwise prejudice any such
right, power, or remedy.

         6.9     Application of Payments. Prior to the Revolving Loan Maturity
Date or any acceleration of the Credit Obligations, all payments made hereunder
shall be applied to the Credit Obligations as directed by the Borrower, subject
to the rules regarding the application of payments to certain Credit
Obligations provided for hereunder and in the Credit Documents.  Following the
Revolving Loan Maturity Date or any acceleration of the Credit Obligations, all
payments and collections shall be applied to the Credit Obligations in the
following order:

                 First, to the payment of the costs, expenses, reimbursements
                 (other than reimbursement obligations with respect to draws
                 under Letters of Credit), and indemnifications of the Agent
                 that are due and payable under the Credit Documents;





                                      -49-
<PAGE>   55
                 Then, ratably to the payment of the costs, expenses,
                 reimbursements (other than reimbursement obligations with
                 respect to draws under Letters of Credit), and
                 indemnifications of the Banks that are due and payable under
                 the Credit Documents;

                 Then, ratably to the payment of all accrued but unpaid
                 interest and fees and obligations under Interest Hedge
                 Agreements due and payable under the Credit Documents;

                 Then, ratably to the payment of all outstanding principal and
                 reimbursement obligations for draws under Letters of Credit
                 due and payable under the Credit Documents;

                 Then, ratably to the payment of any other amounts due and
                 owing with respect to the Credit Obligations; and

                 Finally, any surplus held by the Agent and remaining after
                 payment in full of all the Credit Obligations and reserve for
                 Credit Obligations not yet due and payable shall be promptly
                 paid over to the Borrower or to whomever may be lawfully
                 entitled to receive such surplus.  All applications shall be
                 distributed in accordance with Section 2.10(a).

ARTICLE 7.  THE AGENT AND THE ISSUING BANK

         7.1     Authorization and Action.  Each Bank hereby appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof and of the other Credit Documents, together with such powers as are
reasonably incidental thereto.  Statements under the Credit Documents that the
Agent may take certain actions, without further qualification, means that the
Agent may take such actions with or without the consent of the Banks or the
Majority Banks, but where the Credit Documents expressly require the
determination of the Banks or the Majority Banks, the Agent shall not take any
such action without the prior written consent thereof.  As to any matters not
expressly provided for by this Agreement or any other Credit Document
(including, without limitation, enforcement or collection of the Revolving Loan
Notes), the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the written
instructions of the Majority Banks, and such instructions shall be binding upon
all Banks and all holders of Revolving Loan Notes; provided, however, that the
Agent shall not be required to take any action which exposes the Agent to
personal liability or which is contrary to this Agreement, any other Credit
Document, or applicable law.

         7.2     Reliance, Etc.  Neither the Agent, the Issuing Bank, nor any
of their respective Related Parties (for the purposes of this Section 7.2,
collectively, the "Indemnified Parties") shall be liable for any action taken
or omitted to be taken by any Indemnified Party under or in connection





                                      -50-
<PAGE>   56
with this Agreement or the other Credit Documents, INCLUDING ANY INDEMNIFIED
PARTY'S OWN NEGLIGENCE, except for any Indemnified Party's gross negligence or
willful misconduct.  Without limitation of the generality of the foregoing, the
Agent and the Issuing Bank:  (a) may treat the payee of any Revolving Loan Note
as the holder thereof until the Agent receives written notice of the assignment
or transfer thereof signed by such payee and in form satisfactory to the Agent;
(b) may consult with legal counsel (including counsel for the Borrower),
independent public accountants, and other experts selected by it and shall not
be liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants, or experts; (c) makes
no warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties, or representations made in or in
connection with this Agreement or the other Credit Documents; (d) shall not
have any duty to ascertain or to inquire as to the performance or observance of
any of the terms, covenants, or conditions of this Agreement or any other
Credit Document on the part of the Credit Parties or to inspect the property
(including the books and records) of the Credit Parties; (e) shall not be
responsible to any Bank for the due execution, legality, validity,
enforceability, genuineness, sufficiency, or value of this Agreement or any
other Credit Document; and (f) shall incur no liability under or in respect of
this Agreement or any other Credit Document by acting upon any notice, consent,
certificate, or other instrument or writing (which may be by telecopier or
telex) reasonably believed by it to be genuine and signed or sent by the proper
party or parties.

         7.3     Affiliates.  With respect to its Revolving Loan Commitments,
the Revolving Loan Advances made by it, its interests in the Letters of Credit,
and the Revolving Loan Notes issued to it, the Agent and the Issuing Bank shall
have the same rights and powers under this Agreement as any other Bank and may
exercise the same as though it were not the Agent.  The term "Bank" or "Banks"
shall, unless otherwise expressly indicated, include the Agent and the Issuing
Bank in their individual capacity.  The Agent, the Issuing Bank, and their
respective Affiliates may accept deposits from, lend money to, act as trustee
under indentures of, and generally engage in any kind of business with, any
Credit Party, and any Person who may do business with or own securities of any
Credit Party, all as if the Agent were not an agent hereunder  and the Issuing
Bank were not the issuer of Letters of Credit hereunder and without any duty to
account therefor to the Banks.

         7.4     Bank Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank and based
on the Registration Statement, the Interim Financial Statements, and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it shall, independently and without reliance upon the Agent
or any other Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

         7.5     Expenses.  To the extent not paid by the Borrower, each Bank
severally agrees to pay to the Agent and the Issuing Bank on demand such Bank's
ratable share of the following: (a) all reasonable out-of-pocket costs and
expenses of the Agent and the Issuing Bank in connection with





                                      -51-
<PAGE>   57
the preparation, execution, delivery, administration, modification, and
amendment of this Agreement and the other Credit Documents, including the
reasonable fees and expenses of outside counsel for the Agent and the Issuing
Bank with respect to advising the Agent and the Issuing Bank as to their
respective rights and responsibilities under this Agreement and the Credit
Documents, and (b) all out-of-pocket costs and expenses of the Agent and the
Issuing Bank in connection with the preservation or enforcement of the rights
of the Agent, the Issuing Bank, and the Banks under this Agreement and the
other Credit Documents, whether through negotiations, legal proceedings, or
otherwise, including fees and expenses of counsel for the Agent and the Issuing
Bank.  The provisions of this paragraph shall survive the repayment and
termination of the credit provided for under this Agreement and any purported
termination of this Agreement which does not expressly refer to this paragraph.

         7.6     Indemnification.  To the extent not reimbursed by the
Borrower, each Bank severally agrees to protect, defend, indemnify, and hold
harmless the Agent, the Issuing Bank, and each of their respective Related
Parties (for the purposes of this Section 7.6, collectively, the "Indemnified
Parties"), from and against all demands, claims, actions, suits, damages,
judgments, fines, penalties, liabilities, and out-of-pocket costs and expenses,
including reasonable costs of attorneys and related costs of experts such as
accountants (collectively, the "Indemnified Liabilities"), actually incurred by
any Indemnified Party which are related to any litigation or proceeding
relating to this Agreement, the Credit Documents, or the transactions
contemplated thereunder, INCLUDING ANY INDEMNIFIED LIABILITIES CAUSED BY ANY
INDEMNIFIED PARTY'S OWN NEGLIGENCE, but not Indemnified Liabilities which are a
result of any Indemnified Party's gross negligence or willful misconduct.  The
provisions of this paragraph shall survive the repayment and termination of the
credit provided for under this Agreement and any purported termination of this
Agreement which does not expressly refer to this paragraph.

         7.7     Successor Agent and Issuing Bank.  The Agent or the Issuing
Bank may resign at any time by giving written notice thereof to the Banks and
the Borrower and may be removed at any time with or without cause by the
Majority Banks upon receipt of written notice from the Majority Banks to such
effect.  Upon receipt of notice of any such resignation or removal, the
Majority Banks shall have the right to appoint a successor Agent or Issuing
Bank with the consent of the Borrower, which consent shall not be unreasonably
withheld.  If no successor Agent or Issuing Bank shall have been so appointed
by the Majority Banks with the consent of the Borrower, and shall have accepted
such appointment, within 30 days after the retiring Agent's or Issuing Bank's
giving of notice of resignation or the Majority Banks' removal of the retiring
Agent or Issuing Bank, then the retiring Agent or Issuing Bank may, on behalf
of the Banks and the Borrower, appoint a successor Agent or Issuing Bank, which
shall be, in the case of a successor agent, a commercial bank organized under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $500,000,000 and, in the case of the
Issuing Bank, a Bank.  Upon the acceptance of any appointment as Agent or
Issuing Bank by a successor Agent or Issuing Bank, such successor Agent or
Issuing Bank shall thereupon succeed to and become vested with all the rights,
powers, privileges, and duties of the retiring Agent or Issuing Bank, and the
retiring Agent or Issuing Bank





                                      -52-
<PAGE>   58
shall be discharged from any duties and obligations under this Agreement and
the other Credit Documents after such acceptance, except that the retiring
Issuing Bank shall remain the Issuing Bank with respect to any Letters of
Credit outstanding on the effective date of its resignation or removal and the
provisions affecting the Issuing Bank with respect to such Letters of Credit
shall inure to the benefit of the retiring Issuing Bank until the termination
of all such Letters of Credit.  After any Agent's or Issuing Bank's resignation
or removal hereunder as Agent or Issuing Bank, the provisions of this Article 7
shall inure to such Person's benefit as to any actions taken or omitted to be
taken by such Person while such Person was Agent or Issuing Bank under this
Agreement and the other Credit Documents.

ARTICLE 8.       MISCELLANEOUS.

         8.1     Expenses.  The Borrower shall pay on demand of the applicable
party specified herein (a) all reasonable out-of-pocket costs and expenses of
the Agent and the Issuing Bank in connection with the preparation, execution,
delivery, administration, modification, and amendment of this Agreement and the
other Credit Documents, including the reasonable fees and expenses of outside
counsel for the Agent and the Issuing Bank, and (b) all out-of-pocket costs and
expenses of the Agent, the Issuing Bank, and each Bank in connection with the
preservation or enforcement of their respective rights under this Agreement and
the other Credit Documents, whether through negotiations, legal proceedings, or
otherwise, including fees and expenses of counsel for the Agent, the Issuing
Bank, and each Bank.  The provisions of this paragraph shall survive the
repayment and termination of the credit provided for under this Agreement and
any purported termination of this Agreement which does not expressly refer to
this paragraph.

         8.2     Indemnification.  The Borrower agrees to protect, defend,
indemnify, and hold harmless the Agent, the Issuing Bank, each Bank, and each
of their respective Related Parties (for the purposes of this Section 8.2,
collectively, the "Indemnified Parties"), from and against all demands, claims,
actions, suits, damages, judgments, fines, penalties, liabilities, and
out-of-pocket costs and expenses, including reasonable costs of attorneys and
related costs of experts such as accountants (collectively, the "Indemnified
Liabilities"), actually incurred by any Indemnified Party which are related to
any litigation or proceeding relating to this Agreement, the Credit Documents,
or the transactions contemplated thereunder, INCLUDING ANY INDEMNIFIED
LIABILITIES CAUSED BY ANY INDEMNIFIED PARTY'S OWN NEGLIGENCE, but not
Indemnified Liabilities which are a result of any Indemnified Party's gross
negligence or willful misconduct.  The provisions of this paragraph shall
survive the repayment and termination of the credit provided for under this
Agreement and any purported termination of this Agreement which does not
expressly refer to this paragraph.

         8.3     Modifications, Waivers, and Consents.  No modification or
waiver of any provision of this Agreement or the Revolving Loan Notes, nor any
consent required under this Agreement or the Revolving Loan Notes, shall be
effective unless the same shall be in writing and signed by the Majority Banks
and the Borrower, and then such modification, waiver, or consent shall be
effective

(a) waive any of the conditions specified in Section 3.1 or 3.2, (b) increase
the Revolving Loan Commitments of the Banks, (c) forgive or reduce the amount
or rate of any principal, interest, or fees payable under the Credit Documents,
or postpone or extend the time for payment thereof, (d) release any Guaranty or
any material collateral securing the Credit Obligations (except as otherwise
permitted or required herein), or (e) change the percentage of Banks required
to take any action under this Agreement, the Revolving Loan Notes, or the
Security Documents, including any amendment of the definition of "Majority
Banks" or this Section 8.3.  No modification, waiver, or consent shall, unless
in writing and signed by the Agent or the Issuing Bank affect the rights or
obligations of the Agent or the Issuing Bank, as the case may be, under the
Credit Documents.  The Agent shall not modify or waive or grant any consent
under any other Credit Document of such action would be prohibited under this
Section 8.3 with respect to the Credit Agreement or the Revolving Loan Notes.

         8.4     Survival of Agreements.  All representations, warranties, and
covenants of the Borrower in this Agreement and the Credit Documents shall
survive the execution of this Agreement and the Credit Documents and any other
document or agreement.

         8.5     Assignment and Participation.  This Agreement and the Credit
Documents shall bind and inure to the benefit of the Borrower and their
respective successors and assigns and the Agent and the Banks and their
respective successors and assigns.  The Borrower may not assign its rights or
delegate its duties under this Agreement or any Credit Document.

                 (a)      Assignments.  Any Bank may assign to one or more
banks or other entities all or any portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Revolving Loan Commitments, the Revolving Loan Advances owing to it, the
Revolving Loan Notes held by it, and the participation interest in the Letters
of Credit owned by it); provided, however, that (i) each such assignment shall
be of a constant, and not a varying, percentage of all of such Bank's rights
and obligations under this Agreement, (ii) assignments of Revolving Loan
Commitments shall be made in minimum amounts of $5,000,000 and be made in
integral multiples of $1,000,000 and the assigning Bank, if it retains any
Revolving Loan Commitments, shall maintain at least $5,000,000 in Revolving
Loan Commitments, (iii) each such assignment shall be to an Eligible Assignee,
(iv) the parties to each such assignment shall execute and deliver to the
Agent, for its acceptance and recording in the Register, an Assignment and
Acceptance, together with the Revolving Loan Notes subject to such assignment,
and (v) each Eligible Assignee (other than the Eligible Assignee of the Agent)
shall pay to the Agent a $3,500 administrative fee.  Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment and Acceptance, which effective date shall be at least three
Business Days after the execution thereof, (A) the assignee thereunder shall be
a party hereto for all purposes and, to the extent that rights and obligations
hereunder have been assigned to it pursuant to such Assignment and Acceptance,
have the rights and obligations of a Bank hereunder and (B) such Bank
thereunder





                                      -54-
<PAGE>   60
shall, to the extent that rights and obligations hereunder have been assigned
by it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of such Bank's
rights and obligations under this Agreement, such Bank shall cease to be a
party hereto).

                 (b)      Term of Assignments.  By executing and delivering an
Assignment and Acceptance, the Bank thereunder and the assignee thereunder
confirm to and agree with each other and the other parties hereto as follows:
(i) other than as provided in such Assignment and Acceptance, such Bank makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency of value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such Bank makes no representation or warranty
and assumes no responsibility with respect to the financial condition of any
Credit Party or the performance or observance by any Credit Party of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the Registration Statement and such
other documents and information as it has deemed appropriate to make its own
credit analysis and decision to enter into such Assignment and Acceptance; (iv)
such assignee shall, independently and without reliance upon the Agent, such
Bank or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement as are delegated to the Agent by the
terms hereof, together with such powers as are reasonably incidental thereto;
and (vi) such assignee agrees that it shall perform in accordance with their
terms all of the obligations which by the terms of this Agreement are required
to be performed by it as a Bank.

                 (c)      The Register.  The Agent shall maintain at its
address referred to in Section 8.6 a copy of each Assignment and Acceptance
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Banks and the Revolving Loan Commitments of each Bank from
time to time (the "Register").  The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the
Agent, the Issuing Bank, and the Banks may treat each Person whose name is
recorded in the Register as a Bank hereunder for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower or
any Bank at any reasonable time and from time to time upon reasonable prior
notice.





                                      -55-
<PAGE>   61
                 (d)      Procedures.  Upon its receipt of an Assignment and
Acceptance executed by a Bank and an Eligible Assignee, together with the
Revolving Loan Notes subject to such assignment, the Agent shall, if such
Assignment and Acceptance has been completed in the appropriate form, (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register, and (iii) give prompt notice thereof to the Borrower.
Within five Business Days after its receipt of such notice, the Borrower shall
execute and deliver to the Agent in exchange for the surrendered Revolving Loan
Notes a new Revolving Loan Note to the order of such Eligible Assignee in an
amount equal to the Revolving Loan Commitment assumed by it pursuant to such
Assignment and Acceptance and, if such Bank has retained any Revolving Loan
Commitment hereunder, a new Revolving Loan Note to the order of such Bank in an
amount equal to the Revolving Loan Commitment retained by it hereunder.  Such
new Revolving Loan Notes shall be dated the effective date of such Assignment
and Acceptance and shall be in the appropriate form.

                 (e)      Participation.  Each Bank may sell participation to
one or more banks or other entities in or to all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Revolving Loan Commitments, the Revolving Loan Advances owing to
it, its participation interest in the Letters of Credit, and the Revolving Loan
Notes held by it); provided, however, that (i) such Bank's obligations under
this Agreement (including, without limitation, its Revolving Loan Commitments
to the Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of any such Revolving Loan
Notes for all purposes of this Agreement, (iv) the Borrower, the Agent, and the
Issuing Bank and the other Banks shall continue to deal solely and directly
with such Bank in connection with such Bank's rights and obligations under this
Agreement, and (v) such Bank shall not require the participant's consent to any
matter under this Agreement, except that upon 10 days' written notice of such
participation to the Agent and the Borrower, such Bank may permit the
participant to possess consent rights with respect to changes in the principal
amount of the Revolving Loan Notes, reductions in fees or interest, extensions
of the applicable maturity date, or releases of any collateral or guarantor
(except to the extent otherwise permitted herein or in any of the other Credit
Documents).  The Borrower hereby agrees that participants shall have the same
rights under Sections 2.6, 2.7, 2.8, 2.9, 2.10, and 8.2 as a Bank to the extent
of their respective participation.

                 (f)      Assignments or Pledges to Federal Reserve Banks.  In
addition to the foregoing rights of assignment and participation, any Bank may
assign or pledge any portion of its rights under this Agreement (including the
Revolving Loan Advances owed to such Bank) to any Federal Reserve Bank in
accordance with applicable law without notice to or the consent of the Borrower
or the Agent, provided that (i) such Bank shall not be relieved of its
obligations under this Agreement as





                                      -56-
<PAGE>   62
a result thereof and (ii) in no event shall the Federal Reserve Bank be
entitled to direct the actions of the pledging or assigning Bank under this
Agreement.

         8.7     Choice of Law.  This Agreement and the Revolving Loan Notes
have been prepared, are being executed and delivered, and are intended to be
performed in the State of Texas, and the substantive laws of the State of Texas
and the applicable federal laws of the United States shall govern the validity,
construction, enforcement, and interpretation of this Agreement and the
Revolving Loan Notes; provided however, Chapter 15 of the Texas Credit Code
does not apply to this Agreement or the Revolving Loan Notes.  Each Letter of
Credit shall be governed by the Uniform Customs and Practice for Documentary
Credits, International Chamber of Commerce Publication No. 500 (1993 version).

         8.8     Forum Selection.  THE BORROWER IRREVOCABLY CONSENTS TO THE
JURISDICTION OF THE COURTS OF THE STATE OF TEXAS AND OF ANY FEDERAL COURT
LOCATED IN SUCH STATE IN CONNECTION WITH ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO THE CREDIT DOCUMENTS OR ANY TRANSACTIONS RELATED THERETO.
THE BORROWER AGREES AND SHALL NOT CONTEST THAT PROPER FORUM AND VENUE FOR ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE CREDIT DOCUMENTS OR ANY
TRANSACTIONS RELATING THERETO ARE IN THE COURTS OF THE STATE OF TEXAS IN HARRIS

FORUM.

         8.9     Service of Process.  IN ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO THE CREDIT DOCUMENTS OR ANY TRANSACTIONS RELATING THERETO,
THE BORROWER WAIVES PERSONAL SERVICE OF ANY SUMMONS,





                                      -57-

COMPLAINT, OR OTHER PROCESS OR NOTICE AND AGREES THAT SERVICE BY FIRST CLASS
MAIL, RETURN RECEIPT REQUESTED, TO THE BORROWER AT ITS ADDRESS FOR NOTICES

         8.10    Waiver of Jury Trial.  THE BORROWER IRREVOCABLY WAIVES ANY
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THE CREDIT DOCUMENTS OR ANY TRANSACTIONS RELATING THERETO.

         8.11    Amendment and Restatement.  This Agreement represents a full
and complete amendment and restatement of the Credit Agreement dated as of
January 30, 1998, among the Borrower, NationsBank of Texas, N.A., as
predecessor in interest to NationsBank, N.A., as the Agent, and the Banks named
therein, and that prior version is deemed replaced hereby as of the
effectiveness of this Agreement.  The indebtedness under such prior version of
this Agreement continues under this Agreement (as reallocated among the Banks
in connection with the effectiveness of this Agreement) and the execution of
this Agreement does not indicate a payment, satisfaction, novation, or
discharge thereof.  All security and support for the indebtedness under the
prior version of this Agreement continues to secure and support the
indebtedness hereunder.  Upon the effectiveness of this Agreement, all
outstanding Revolving Loan Advances shall be reallocated among the Banks
ratably in accordance with their Commitments.  Amounts payable under the prior
version of this Agreement shall accrue thereunder until the effectiveness of
this Agreement and the Agent shall arrange with the Borrower and the Banks to
prorate and ratably distribute to the Agent and the Banks all amounts payable
under the prior version of this Agreement for the periods prior to the
effectiveness of this Agreement.

         8.12    Counterparts.  This Agreement may be executed in multiple
counterparts which together shall constitute one and the same instrument.

         8.13    No Further Agreements.  THIS WRITTEN AGREEMENT AND THE CREDIT
DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                                    GUARANTY
             (Subsidiaries of Integrated Electrical Services, Inc.)


        This Guaranty dated as of July 30, 1998 ("Agreement"), is made by the
undersigned subsidiaries of Integrated Electrical Services, Inc., a Delaware
corporation (each a "Guarantor"), in favor of NationsBank, N.A., successor in
interest by merger to NationsBank of Texas, N.A., in its capacity as agent
("Agent") for certain financial institutions which are or may become parties to
the Credit Agreement described below.

                                  INTRODUCTION

        This Agreement is given in connection with the Credit Agreement dated
as of July 30, 1998 (as modified from time to time, the "Credit Agreement"),
among Integrated Electrical Services, Inc., a Delaware corporation
("Borrower"), certain financial institutions which are or may become parties
thereto, and the Agent, the defined terms of which are used herein unless
otherwise defined herein.  It is a condition precedent to the obligation of the
Banks to make any extension of credit under the Credit Agreement that the
Guarantors execute and deliver this Agreement to the Agent.  Each Guarantor is
a Subsidiary of the Borrower.  Because each Guarantor receives and, as a result
of its ownership by the Borrower, expects to continue to receive financial and
management support from the Borrower, each Guarantor will obtain substantial
benefit from the extensions of credit expected to be made to the Borrower under
the Credit Agreement.


        Therefore, to induce the Agent and such financial institutions to
enter into the Credit Agreement, the Guarantors jointly and severally agree
with the Agent as follows:

Section 1.       Guaranty. The Guarantors irrevocably and jointly and
severally guarantee to the Agent the full payment when due of (a) all
principal, interest, fees, reimbursements, indemnifications, and other amounts
now or hereafter owed by the Borrower to the Agent and the Banks (and with
respect to the Interest Hedge Agreements, the Affiliates of the Banks) under
the terms of the Credit Agreement and the other Credit Documents, including
amounts owed under the terms of the Credit Agreement and the other Credit
Documents for which the Borrower has obtained relief under bankruptcy or other
laws providing for relief from creditors, and (b) any increases, extensions,
and rearrangements of the foregoing obligations under any amendments,
supplements, and other modifications of the documents and agreements creating
the foregoing obligations (collectively, the "Guaranteed

<PAGE>   69
Obligations").  This is a guaranty of payment and not merely a guaranty of
collection, and each Guarantor is liable as a primary obligor.  If any of the
Guaranteed Obligations are not punctually paid when due, whether by maturity,
acceleration, or otherwise, and the Agent shall notify any Guarantor of such
default and make demand for payment hereunder, such Guarantor shall immediately
pay to the Agent the full amount of the Guaranteed Obligations which are due
and payable.  Each Guarantor shall make each payment to the Agent in U.S.
Dollars in immediately available funds as directed by the Agent.  The Agent is
hereby authorized at any time following any demand for payment hereunder to set
off and apply any indebtedness owed by the Agent to any Guarantor against any
and all of the obligations of such Guarantor under this Agreement.  The Agent
agrees to promptly notify such Guarantor after any such setoff and application,
but the failure to give such notice shall not affect the validity of such
setoff and application.

Section 2.       Guaranty Absolute.

        2.1      This Agreement shall be deemed accepted by the Agent upon
receipt, and the obligations of the Guarantors under this Agreement are
effective immediately and are continuing and cover all Guaranteed Obligations
arising prior to and after the date hereof.  This Agreement may not be revoked
by any Guarantor and shall continue to be effective with respect to Guaranteed
Obligations arising or created after any attempted revocation by any Guarantor.

        2.2      Each Guarantor guarantees that the Guaranteed Obligations will
be paid strictly in accordance with the terms of the Credit Agreement and the
other Credit Documents, regardless of any law, regulation, or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Agent or the Banks with respect thereto.  Each Guarantor agrees
that such Guarantor's obligations under this Agreement shall not be released,
diminished, or impaired by, and waives any rights which such Guarantor might
otherwise have which relate to:

                 (a)      Any lack of validity or enforceability of the
Guaranteed Obligations, any Credit Document, or any other agreement or
instrument relating thereto; any increase, reduction, extension, or
rearrangement of the Guaranteed Obligations; any amendment, supplement, or
other modification of the Credit Documents; any waiver or consent granted under
the Credit Documents, including waivers of the payment and performance of the
Guaranteed Obligations; or any sale, assignment, delegation, or other transfer
of the Guaranteed Obligations or the Credit Documents;

                 (b)      Any grant of any security or support for the
Guaranteed Obligations or any impairment of any security or support for the
Guaranteed Obligations, including any

<PAGE>   70
full or partial release, exchange, subordination, or waste of any collateral
for the Guaranteed Obligations or any full or partial release of the Borrower,
any Guarantor, or any other Person liable for the payment or performance of the
Guaranteed Obligations; any change in the organization or structure of the
Borrower, any Guarantor, or any other Person liable for the payment or
performance of the Guaranteed Obligations; or the insolvency, bankruptcy,
liquidation, or dissolution of the Borrower, any Guarantor, or any other Person
liable for the payment or performance of the Guaranteed Obligations;

                 (c)      The manner of applying payments on the Guaranteed
Obligations or the proceeds of any security or support for the Guaranteed
Obligations against the Guaranteed Obligations;

                 (d)      The failure to give notice of the occurrence of any
of the events or actions referred to in this Section 2.2, notice of any default
or event of default, however denominated, under the Credit Documents, notice of
intent to demand, notice of demand, notice of presentment for payment, notice
of nonpayment, notice of intent to protest, notice of protest, notice of grace,
notice of dishonor, notice of intent to accelerate, notice of acceleration,
notice of bringing of action to enforce the payment or performance of the
Guaranteed Obligations, notice of any sale or foreclosure of any collateral for
the Guaranteed Obligations, notice of any transfer of the Guaranteed
Obligations, notice of the financial condition of or other circumstances
regarding the Borrower, any Guarantor, or any other Person liable for the
Guaranteed Obligations, or any other notice of any kind relating to the
Guaranteed Obligations (and the parties intend that no Guarantor shall be
considered a "Debtor" as defined in Section 9.105 of the Texas Business and
Commerce Code for the purpose of notices required to be given to a Debtor
thereunder); or

                 (e)      Any other action taken or omitted which affects the
Guaranteed Obligations, whether or not such action or omission prejudices any
Guarantor or increases the likelihood that any Guarantor will be required to
pay the Guaranteed Obligations pursuant to the terms hereof--it is the
unambiguous and unequivocal intention of each Guarantor that such Guarantor
shall be obligated to pay the Guaranteed Obligations when due, notwithstanding
any occurrence, circumstance, event, action, or omission whatsoever, whether
contemplated or uncontemplated, and whether or not particularly described
herein.

         2.3     This Agreement shall continue to be effective or be
reinstated, as the case may be, if any payment on the Guaranteed Obligations
must be refunded for any reason including any bankruptcy proceeding.  In the
event that the Agent or any Bank must refund any payment received against the
Guaranteed Obligations, any prior release from the terms of this Agreement
given to any Guarantor by the Agent shall be without effect, and this Agreement
shall be reinstated in full force and effect.  It is the intention of each
Guarantor that such





                                      -3-
<PAGE>   71
Guarantor's obligations hereunder shall not be discharged except by final
payment of the Guaranteed Obligations.

        2.4      (a)      Each Guarantor is a Subsidiary of the Borrower and
receives and, because of its ownership by the Borrower, expects to continue to
receive business opportunities, financial support, and management support from
the Borrower.  Each Guarantor has agreed to enter into this Agreement so that
the Borrower can receive the benefits of the Guaranteed Obligations and
continue to provide these services to such Guarantor.

                 (b)      In consummating the transactions contemplated by the
Credit Documents, no Guarantor intends to disturb, delay, hinder, or defraud
either present or future creditors of such Guarantor.  Each Guarantor is
familiar with, and has independently reviewed books and records regarding, the
financial condition of the Borrower and is familiar with the value of the
security and support for the payment and performance of the Guaranteed
Obligations.  Based upon such examination, and taking into account the fairly
discounted value of such Guarantor's contingent obligations under this
Agreement and the value of the subrogation and contribution claims such
Guarantor could make in connection with this Agreement, and assuming each of
the transactions contemplated by the Credit Documents is consummated and the
Borrower makes full use of the credit facilities thereunder, the present
realizable fair market value of the assets of such Guarantor exceeds the total
obligations of such Guarantor, and such Guarantor is able to realize upon its
assets and pay its obligations as such obligations mature in the normal course
of business.

                 (c)      If notwithstanding the foregoing it is judicially
determined with respect to any Guarantor that entering into this Agreement
would violate Section 548 of the United States Bankruptcy Code or any
comparable provisions of any state law, then such Guarantor shall be liable
under this Guaranty only for amounts aggregating up to the largest amount that
would not render such Guarantor's obligations hereunder subject to avoidance
under Section 548 of the United States Bankruptcy Code or any comparable
provisions of any state law.

                 (d)      Each Guarantor agrees that each Guarantor shall have
rights of contribution and subrogation against each other Guarantor with
respect to any payments made in connection with the Guaranteed Obligations.

Section 3.       Unimpaired Collection.

        3.1      There are no conditions precedent to the enforcement of this
Agreement, except as expressly contained herein.  It shall not be necessary for
the Agent, in order to





                                      -4-
<PAGE>   72
enforce payment by any Guarantor under this Agreement, to show any proof of the
Borrower's default, to exhaust the Agent's remedies against the Borrower, any
Guarantor, or any other Person liable for the payment or performance of the
Guaranteed Obligations, to enforce any security or support for the payment or
performance of the Guaranteed Obligations, or to enforce any other means of
obtaining payment or performance of the Guaranteed Obligations.  Each Guarantor
waives any rights under Chapter 34 of the Texas Business and Commerce Code,
Section 17.001 of the Texas Civil Practice and Remedies Code, and Rule 31 of
the Texas Rules of Civil Procedure related to the foregoing.  Neither the Agent
nor the Banks shall be required to mitigate damages or take any other action to
reduce, collect, or enforce the Guaranteed Obligations.

        3.2      With respect to each Guarantor, all Subordinated Obligations
of such Guarantor (as defined below) shall be subordinate and junior in right
of payment and collection to the payment and collection in full of all
Guaranteed Obligations as described below:

                 (a)  As used herein, the term "Subordinated Obligations" for
such Guarantor means: (i) all present and future indebtedness, liabilities, and
obligations of any kind owed by the Borrower, any Guarantor, or any other
Person liable for the payment or performance of the Guaranteed Obligations to
such Guarantor, including debt obligations, equity obligations, and other
contractual obligations requiring payments of any kind to be made to such
Guarantor and including any right of subrogation (including any statutory
rights of subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C.
Section  509, or under Chapter 34 of the Texas Business and Commerce Code),
contribution, indemnification, reimbursement, exoneration, or any right to
participate in any claim or remedy of the Agent against the Borrower, any
Guarantor, or any Person liable for the payment or performance of the
Guaranteed Obligations, or any collateral which the Agent now has or may
acquire, and (ii) any increases, extensions, and rearrangements of the
foregoing obligations under any amendments, supplements, and other
modifications of the documents and agreements creating the foregoing
obligations.

                 (b)      Until all Guaranteed Obligations have been
irrevocably paid in full (and therefore the payment thereof is no longer
subject to being set aside or returned under the law), such  Guarantor agrees
not to take any action to enforce payment of such the Subordinated Obligations
of such Guarantor, but this standstill is not intended as a permanent waiver of
the subrogation, contribution, indemnification, reimbursement, exoneration,
participation, or other rights of such Guarantor.

                 (c)      Upon any receivership, insolvency proceeding,
bankruptcy proceeding, assignment for the benefit of creditors, reorganization,
arrangement with creditors, sale of





                                      -5-
<PAGE>   73
assets for creditors, dissolution, liquidation, or marshaling of the assets of
the Borrower, any Guarantor, or any other Person liable for the payment or
performance of the Guaranteed Obligations, all amounts due with respect to the
Guaranteed Obligations shall be paid in full before such Guarantor shall be
entitled to collect or receive any payment with respect to the Subordinated
Obligations of such Guarantor, and all payments to which such Guarantor would
be entitled to collect or receive on the Subordinated Obligations of such
Guarantor shall be paid over to the Agent for application to the Guaranteed
Obligations.

                 (d)      Following notice from the Agent to the Borrower that
an Event of Default exists and that no further payments shall be made on the
Subordinated Obligations of such Guarantor until (i) all amounts due with
respect to the Guaranteed Obligations shall be paid in full or (ii) the Agent
revokes such notice, such Guarantor shall not be entitled to collect or receive
any payment with respect to the Subordinated Obligations of such Guarantor.

                 (e)      Any lien, security interest, or assignment securing
the repayment of the Subordinated Obligations of such Guarantor shall be fully
subordinate to any lien, security interest, or assignment in favor of the Agent
which secures the Guaranteed Obligations.  At the request of the Agent, such
Guarantor will take any and all steps necessary to fully evidence the
subordination granted hereunder, including amending or terminating financing
statements and executing and recording subordinations of liens.

                 (f)      This is an absolute and irrevocable agreement of
subordination and the Agent may, without notice to such Guarantor, take any
action described in Section 2.2 without impairing or releasing the obligations
of such Guarantor hereunder.

                 (g)      Such Guarantor shall not assign or otherwise transfer
to any other Person any interest in the Subordinated Obligations of such
Guarantor unless such Guarantor causes the assignee or other transferee to
execute and deliver to the Agent a subordination agreement in substantially the
form of the subordination provisions in this Agreement.

                 (h)  If any amount shall be paid to such Guarantor in
violation of this Section 3.2, such amount shall be held in trust for the
benefit of the Agent and immediately turned over to the Agent, with any
necessary endorsement, to be applied to the Guaranteed Obligations.

Section 4.       Miscellaneous.

        4.1      Each Guarantor hereby affirms and shall comply with the
representations, warranties, and covenants made by the Borrower in the Credit
Agreement to the extent that





                                      -6-
<PAGE>   74
such representations, warranties, and covenants are applicable to such
Guarantor, including all of the representations and warranties in Section 4 of
the Credit Agreement and all of the covenants in Section 5 of the Credit
Agreement.

         4.2     Each Guarantor shall pay to the Agent on demand (a) all
reasonable out-of-pocket costs and expenses of the Agent in connection with the
preparation, execution, delivery, administration, modification, and amendment
of this Agreement and the other Credit Documents to which such Guarantor is a
party, including the reasonable fees and out-of-pocket expenses of outside
counsel for the Agent with respect to advising the Agent as to its rights and
responsibilities under this Agreement and the Credit Documents to which such
Guarantor is a party, and (b) all costs and expenses of the Agent in connection
with the enforcement of the Agent's rights under this Agreement and the other
Credit Documents to which such Guarantor is a party, whether through
negotiations, legal proceedings, or otherwise, including fees and expenses of
counsel for the Agent.  The provisions of this paragraph shall survive any
purported termination of this Agreement and the Credit Documents that does not
expressly reference this paragraph.

         4.3     Each Guarantor agrees to protect, defend, indemnify, and hold
harmless the Agent, each Bank, and each of their respective Related Parties
(collectively, the "Indemnified Parties"), from and against all demands,
claims, actions, suits, damages, judgments, fines, penalties, liabilities, and
costs and expenses, including reasonable costs of attorneys and related costs
of experts such as accountants (collectively, the "Indemnified Liabilities"),
actually incurred by the Indemnified Parties which are related to any
litigation or proceeding relating to this Agreement, the Credit Documents, or
the transactions contemplated thereunder, INCLUDING INDEMNIFIED LIABILITIES
CAUSED BY ANY INDEMNIFIED PARTIES' OWN NEGLIGENCE, but not Indemnified
Liabilities which are a result of any Indemnified Parties' gross negligence or
willful misconduct or negligence in the handling of money.  The provisions of
this paragraph shall survive any purported termination of this Agreement and
the Credit Documents that does not expressly reference this paragraph.

         4.4     Each Guarantor agrees that this Agreement shall be governed by
the laws of the State of Texas.  If any provision in this Agreement is held to
be unenforceable, such provision shall be severed and the remaining provisions
shall remain in full force and effect.  All representations, warranties, and
covenants of any Guarantor in this Agreement shall survive the execution of
this Agreement and any other contract or agreement.  The Agent's remedies under
this Agreement and the Credit Documents to which any Guarantor is a party shall
be cumulative, and no delay in enforcing this Agreement and the Credit
Documents to which such Guarantor is a party shall act as a waiver of the
Agent's rights thereunder.  The provisions of this Agreement may be waived or
amended only in a writing signed by the





                                      -7-
<PAGE>   75
party against whom enforcement is sought.  This Agreement shall bind and inure
to the benefit of each Guarantor and the Agent and their respective successors
and assigns.  Each Guarantor may not assign its rights or delegate its duties
under this Agreement.  The Agent may assign its rights and delegate its duties
under this Agreement in accordance with the terms of the Credit Agreement.
This Agreement may be executed in multiple counterparts each of which shall
constitute one and the same agreement.  Unless otherwise specified, all notices
and other communications between such Guarantor and the Agent provided for in
this Agreement and the Credit Documents to which such Guarantor is a party
shall be in writing, including telecopy, and delivered or transmitted to the
addresses set forth below, or to such other address as shall be designated by

officer of such Guarantor or the Agent, as the case may be.

$[Amount]                        Houston, Texas                          [date]


         For value received, the undersigned INTEGRATED ELECTRICAL SERVICES,
INC., a Delaware corporation ("Borrower"), hereby promises to pay to the order
of [Bank Name] ("Bank"), the principal amount of [Amount] ($[ ]) or, if less,
the aggregate outstanding principal amount of the Revolving Loan Advances (as
defined in the Credit Agreement referred to below) made by the Bank to the
Borrower, together with accrued but unpaid interest on the principal amount of
each such Revolving Loan Advance from the date of such Revolving Loan Advance
until such principal amount is paid in full, at such interest rates, and at such
times, as are specified in the Credit Agreement.

         This Note is one of the Notes referred to in, and is entitled to the
benefits of, and is subject to the terms of, the Credit Agreement dated as of
July 30, 1998 (as the same may be modified from time to time, the "Credit
Agreement"), among the Borrower, the financial institutions parties thereto
("Banks"), and NationsBank, N.A., successor in interest by merger to NationsBank
of Texas, N.A., as agent for the Banks ("Agent"). Capitalized terms used herein
but not defined herein shall have the meanings specified by the Credit
Agreement. The Credit Agreement, among other things, (a) provides for the making
of Revolving Loan Advances by the Bank to the Borrower from time to time, the
indebtedness of the Borrower resulting from each such Revolving Loan Advance
being evidenced by this Note, and (b) contains provisions for acceleration of
the maturity of this Note upon the happening of certain events stated in the
Credit Agreement and for prepayments of principal prior to the maturity of this
Note upon the terms and conditions specified in the Credit Agreement.

         Both principal and interest are payable to the Agent in the currency,
at the times, in the locations, and in the manner specified in the Credit
Agreement. The Bank shall record all Revolving Loan Advances and payments of
principal made under this Note, but no failure of the Bank to make such
recordings shall affect the Borrower's repayment obligations under this Note.

         It is contemplated that because of prepayments there may be times when
no indebtedness is owed under this Note. Notwithstanding such prepayments, this
Note shall remain valid and shall be in force as to Revolving Loan Advances made
pursuant to the Credit Agreement after such prepayments.

         It is the intention of the Bank and the Borrower to conform strictly to
any applicable usury laws. Accordingly, the terms of the Credit Agreement
relating to the prevention of usury will be strictly followed.

         No Further Agreements.  THIS WRITTEN AGREEMENT AND THE CREDIT
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         EXECUTED as of the date first above written.

                                PROMISSORY NOTE
                                  (Swing Line)


$5,000,000.00                                                      July 30, 1998

         INTEGRATED ELECTRICAL SERVICES, INC., a Delaware corporation
("Borrower"), for value received, hereby promises to pay to the order of
NATIONSBANK, N.A., successor in interest by merger to NationsBank of Texas,
N.A. ("Lender"), the principal sum of FIVE MILLION AND NO/100 DOLLARS
($5,000,000.00) or, if less, the outstanding principal amount advanced under
this Promissory Note ("Note") and interest thereon, all as required by this
Note.

         This Note is the Swing Line Note referred to in, and is entitled to
the benefits of, and is subject to the terms of, the Credit Agreement dated as
of July 30, 1998 (as modified from time to time, the "Credit Agreement"), among
the Borrower, the financial institutions parties thereto ("Banks"), and
NationsBank, N.A., successor in interest by merger to NationsBank of Texas,
N.A., as agent for the Banks ("Agent"). Capitalized terms used herein but not
defined herein shall have the meanings specified by the Credit Agreement.

         Subject to the terms of this Note, the Lender shall from time to time
prior to the Maturity Date (hereinafter defined) make advances ("Advances") to
the Borrower under this Note. The aggregate outstanding principal amount of
such advances shall not exceed the face amount of this Note. The Borrower
shall request Advances by providing the Lender with notice not later than 11:00
a.m., Houston, Texas, time on the date of the requested Advance. The request
must specify the amount of the requested Advance and the date of funding for
such Advance. The Lender shall, before 4:00 p.m., Houston, Texas, time on the
date of such Advance, make such Advance available to the Borrower in
immediately available funds at the Borrower's account with the Lender.

         Subject to the terms hereof, the Borrower may prepay the Advances on
this Note by providing the Lender with notice of the intended prepayment not
later than 11:00 a.m., Houston, Texas, time on the date of prepayment,
specifying the amount and the date of such prepayment. Each partial prepayment
of the Advances shall be in a minimum amount of $100,000 or an integral
multiple thereof or, if the aggregate outstanding principal amount of the
Advances would be less than $100,000 following the prepayment, in the remaining
aggregate outstanding principal amount of the Advances, together with accrued
interest to the date of such prepayment on the principal amount prepaid.
Amounts prepaid shall be applied in the inverse order of maturity.

         Notwithstanding anything herein to the contrary, the Borrower shall
pay to the Lender the outstanding principal balance of this Note on July 30,
2001 ("Maturity Date").

<PAGE>   85
         It is contemplated that because of prepayments there may be times when
no indebtedness is owed under this Note. Notwithstanding such prepayments,
this Note shall remain valid and shall be in force as to Advances made pursuant
to the Credit Agreement after such prepayments.

         The Advances shall bear interest at a per annum rate equal to the
difference of (a) (i) the Adjusted Base Rate in effect from time to time plus
(ii) the Applicable Margin for the Prime Rate Tranche in effect from time to
time, calculated on the basis of a 365/366-day year for the actual number of
days elapsed, minus (b) the Applicable Margin for Commitment Fees in effect
from time to time, calculated on the basis of a 360-day year for the actual
number of days elapsed.

         The Borrower shall pay to the Lender all accrued but unpaid interest
on the aggregate outstanding principal amount of the Advances on the last day
of each calendar quarter, when the Advances are prepaid in full, and on the
Maturity Date.

         The Lender shall record in its records all Advances made under this
Note and all payments of principal and interest on the Advances. Any failure
of the Lender to make such recordings, however, shall not affect the Borrower's
repayment obligations. The Lender's records shall be presumptive evidence of
the principal and interest owed by the Borrower.

         The Borrower shall make each payment required under this Note not
later than 12:00 noon, Houston, Texas, time on the date when due in Dollars to
the Lender at such location as is specified by the Lender in writing in
immediately available funds. During the existence of an Event of Default, the
Borrower hereby authorizes the Lender, if and to the extent payment is not made
when due under this Note, to charge from time to time against any account of
the Borrower with the Lender any amount so due. Whenever any payment to be
made under this Note shall be stated to be due on a day other than a day on
which the Lender is open for business in Houston, Texas ("Business Day"), such
payment shall be made on the next succeeding Business Day, and such extension
of time shall in such case be included in the computation of the payment of
interest. All payments shall be applied as directed by the Borrower or, if not
directed by the Borrower, as determined by the Lender.

         Each of the following shall be an "Event of Default" for the purposes
of this Note: (a) the Borrower (i) fails to pay when due any principal amounts
due under this Note or (ii) fails to pay when due any interest or other amounts
due under this Note and such failure has not been cured within five Business
Days, (b) there shall occur any Event of Default under the Credit Agreement, or
(c) the Lender shall resign or be removed as Agent under the Credit Agreement.

         During the continuation of any Event of Default, the Lender may
declare by written notice to the Borrower all of the commitments of the Lender
hereunder terminated (whereupon the same shall terminate) and the Lender may
declare by written notice to the Borrower the aggregate outstanding principal
amount of the Advances, all accrued interest thereon, and all other amounts
payable by the Borrower under this Note to be immediately due and payable
(whereupon the same shall immediately and automatically become due and
payable). Upon the occurrence of any Event

<PAGE>   86
of Default relating to bankruptcy or insolvency, all of the commitments of the
Lender hereunder shall terminate, and the aggregate outstanding principal
amount of all Advances made under this Note, all accrued interest thereon, and
all other amounts payable by the Borrower under this Note shall immediately and
automatically become due and payable.

         Except for the notices provided for above and in the Credit Agreement,
the Borrower waives notice of intent to demand, demand, presentment for
payment, notice of nonpayment, protest, notice of setoff, notice of protest,
notice of dishonor, notice of intent to accelerate, notice of acceleration, and
all other notices in connection with the foregoing.

         During the existence of an Event of Default, the Lender is authorized
at any time, to the fullest extent permitted by law, to setoff and apply any
indebtedness owed by the Lender to the Borrower against any and all of the
obligations of the Borrower under this Note, irrespective of whether or not the
Lender shall have made any demand under this Note and although such obligations
may be contingent and unmatured. Following an Event of Default, the Lender may
exercise (a) all of its rights under this Note and the Credit Agreement
(including Section 2.3(b) thereof) (such agreements being the "Loan Documents")
and (b) all other rights at law or in equity. During the existence of an Event
of Default, all payments and collections shall be applied in the order
determined by the Lender.

         No right, power, or remedy conferred to the Lender in the Credit
Agreement or any Loan Document, or now or hereafter existing at law, in equity,
by statute, or otherwise shall be exclusive, and each such right, power, or
remedy shall to the full extent permitted by law be cumulative and in addition
to every other such right, power or remedy. No course of dealing and no delay
in exercising any right, power, or remedy conferred to the Lender in this Note,
or now or hereafter existing at law, in equity, by statute, or otherwise shall
operate as a waiver of or otherwise prejudice any such right, power, or remedy.
No notice to or demand upon the Borrower shall entitle the Borrower to similar
notices or demands in the future.

         If the Borrower fails to pay when due any amount payable under this
Note, at the request of the Lender the amount not paid when due shall bear
interest beginning on the date due until paid in full at the rate otherwise set
for outstanding principal hereunder plus 2.00%.

         It is the intention of the Lender and the Borrower to conform strictly
to any applicable usury laws. Accordingly, the terms of the Credit Agreement
relating to the prevention of usury will be strictly followed.

         This Note shall be governed by the laws of the State of Texas without
regard to any principles of conflicts of laws. If any provision in this Note
is held to be unenforceable, such provision shall be severed and the remaining
provisions shall remain in full force and effect. All representations,
warranties, and covenants of the Borrower in this Note shall survive the
execution of this Note, the other Loan Documents, and any other contract or
agreement. The Lender's remedies under this Note and the Loan Documents shall
be cumulative, and no delay in enforcing this Note or the other Loan Documents
shall act as a waiver of the Lender's rights hereunder. The provisions





                                      -3-
<PAGE>   87
of this Note may be waived or amended only in a writing signed by the party
against whom enforcement of such waiver or amendment is sought. This Note
shall bind the Borrower and the Borrower's successors and assigns and shall
inure to the benefit of the Lender and the Lender's successors and assigns.
The Borrower may not assign the Borrower's rights or delegate the Borrower's
duties under this Note or the other Loan Documents. The Lender may assign and
participate the Lender's rights and delegate the Lender's duties under this
Note. Unless otherwise specified, all notices provided for in this Note shall
be made in accordance with the terms of the Credit Agreement.

         This Note evidences a modification and extension of certain
indebtedness previously evidenced by that certain promissory note of the
Borrower in favor of NationsBank of Texas, N.A., predecessor in interest to
NationsBank, N.A., dated as of January 30, 1998, in the maximum principal
amount of $5,000,000 (such promissory note is referred to as the "Original
Note"). The indebtedness represented by the Original Note continues under this
Note and the execution of this Note does not indicate a payment, satisfaction,
novation, or discharge thereof. All security and support for the Original Note
and the indebtedness represented thereby continues to secure and support this
Note and the indebtedness hereunder.

         THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         EXECUTED as of the date first above written.

         2.1     Grant of Security Interest.  Each Debtor hereby grants to the

obligated to perform or fulfill any of the obligations of any Debtor
thereunder, including any obligation to make any inquiry as to the nature or
sufficiency of any payment any Debtor may be entitled to receive thereunder, to
present or file any claim, or to take any action to collect or enforce any
claim for payment thereunder.

assets which comprise the Collateral of such Debtor as reflected in such
Debtor's financial statements free from any liens, security interests,
assignments, adverse claims, restrictions, or other encumbrances whatsoever
except the Permitted Liens.  No effective recorded interest, financing
statement, or similar recording or filing covering any part of the Collateral

<PAGE>   91
any lien, security interest, assignment, restriction, claim, or other
encumbrance on or against the Collateral, or lease, sell, or otherwise transfer
any of such Debtor's rights in the Collateral except as otherwise permitted
under this Agreement.

         3.2     Perfection.

                 (a)      General.

                          (i)     As of the date of this Agreement, the true
and correct name of such Debtor as listed on such Debtor's certificate of
incorporation is the name specified for such Debtor on the signature pages of
this Agreement.  Such Debtor has had no prior names other than those listed for
such Debtor in Schedule I.  Such Debtor has not used and does not use any trade
names other than those listed in Schedule I.  Without ten days' advance written
notice to the Secured Party, such Debtor shall not change such Debtor's name.

                          (ii)    As of the date of this Agreement, such
Debtor's chief executive office is located at the Chief Executive Office
Location for such Debtor.  Without ten days' advance written notice to the
Secured Party, such Debtor shall not change the location of such Debtor's chief
executive office from the Chief Executive Office Location for such Debtor.

                          (iii)   A carbon, photographic, or other reproduction
of this Agreement shall be sufficient as a financing statement and may be filed

                 (b)      Perfection of Receivables.

                          (i)     Such Debtor shall provide the Secured Party
with advance written notice of any material increase in the amount of
Receivables in the form of accounts or general intangibles for the payment of
money from governmental agencies that require consents or other actions to
assign, perfect, or realize upon  (including Receivables from the federal
government that are subject to the Federal Assignment of Claims Act),
instruments, and chattel paper and the opportunity to perfect a first priority
security interest (subject only to Permitted Liens) in any such Receivables of
such Debtor.  Upon written request of the Secured Party, such Debtor shall take
such actions as the Secured Party may reasonably request to permit the Secured
Party to perfect a first priority security interest in any such Receivables of
such Debtor, including obtaining necessary consents from governmental agencies,
delivery of instruments to the Secured Party with all necessary endorsements,
and delivery of assignment agreements requested by the Secured Party.

<PAGE>   92
                          (ii)    With respect to Receivables of such Debtor in
the form of chattel paper, such Debtor shall, upon written request from the
Agent, mark conspicuously all such Collateral with a legend, in form and
substance reasonably satisfactory to the Secured Party, indicating that such
Collateral is subject to the security interests granted hereunder.  Such Debtor
shall, during the existence of an Event of Default and upon request by the
Secured Party, promptly deliver to the Secured Party possession of the
Receivables of such Debtor in the form of chattel paper.

                          (iii)   No authorization, consent, or other action is
necessary to allow such Debtor to perform such Debtor's obligations hereunder
with respect to the Receivables of such Debtor in the form of accounts and
general intangibles for the payment of money.

         3.3     Priority.

                 (a)      The security interests created by this Agreement are
or, with respect to any security interest in Collateral of any Subsidiary
acquired by the Borrower in an Acquisition transaction, will be within 30 days
following the closing of such Acquisition, first priority except as set forth
below, subject only to the Permitted Liens, and such Debtor shall preserve and
maintain the status of such security interests to the end that such security
interests remain first priority security interests, except as set forth below,
in the Collateral subject only to the Permitted Liens.  Permitted Liens for
taxes, assessments, or other governmental charges or levies may be first
priority to the extent required by applicable law.

                 (b)      If the proceeds of the Secured Obligations are used
to pay any indebtedness secured by prior liens, the Secured Party is subrogated
to all of the rights and liens of the holders of such indebtedness.

         3.4     Further Assurances.

                 (a)      There are no actions, suits, proceedings, or
investigations pending or, to the knowledge of such Debtor, threatened against
or affecting any material portion of the Collateral, or involving the validity
or enforceability of this Agreement or the priority of the liens, security
interests, or assignments created hereunder with respect to any material
portion of the Collateral.  If the validity or priority of this Agreement or of
any liens, security interests, or assignments created or purported to be
created hereunder or the title of such Debtor to any Collateral of such Debtor
shall be endangered, questioned, or attacked in any material respect or if any
material legal proceedings are instituted against such Debtor with respect
thereto, such Debtor shall give prompt written notice thereof to the Secured
Party, and the action proposed to be taken by such Debtor in connection
therewith.  During the existence of an Event of Default, such Debtor shall not
initiate any action with respect to





                                      -5-
<PAGE>   93
such material matters without granting the Secured Party advance written notice
of such Debtor's intent to initiate such actions and the opportunity to consult
with such Debtor regarding such Debtor's proposed actions (unless immediate
action is necessary to prevent loss to such Debtor).  At the Secured Party's
request, during the existence of an Event of Default, such Debtor shall take
any actions reasonably requested by the Secured Party with respect to such
matters, including diligently endeavoring to cure any material defect existing
or claimed, and taking all reasonably necessary and desirable steps for the
defense of any legal proceedings, including the employment of counsel, the
prosecution or defense of litigation, and the release or discharge of all
adverse claims.  During the existence of an Event of Default, the Secured
Party, whether or not named as a party to any legal proceedings, is authorized
to take any additional steps as the Secured Party deems necessary or desirable
for the defense of any such legal proceedings or the protection of the validity
or priority of this Agreement and the liens, security interests, and
assignments created hereunder, including the employment of independent counsel,
the prosecution or defense of litigation, the compromise or discharge of any
adverse claims made with respect to any Collateral of such Debtor and the
payment or removal of prior liens or security interests, and the reasonable
expenses of the Secured Party in taking such action shall be paid by such
Debtor.  Provided, that the Secured Party shall first request in writing that
such Debtor take such additional steps and such Debtor shall, after reasonable
opportunity, have failed to do so.

                 (b)      Such Debtor agrees that at any time such Debtor shall
promptly execute and deliver all further agreements, and take all further
action, that the Secured Party may reasonably request, in order to further
evidence the liens, security interests, and assignments granted or purported to
be granted hereunder and perfect and protect the same or to enable the Secured
Party to exercise and enforce the Secured Party's rights and remedies
hereunder.  Without limiting the foregoing, such Debtor shall at the Secured
Party's reasonable request execute financing statements, assignments, notices,
certificates of title and applications therefor, and such other documents and
agreements as the Secured Party may reasonably request in order to perfect and
preserve the security interests granted or purported to be granted hereunder.
Such Debtor shall furnish to the Secured Party from time to time any statements
and schedules further identifying and describing any Collateral of such Debtor
and such other reports in connection with the Collateral of such Debtor as the
Secured Party may reasonably request.

                 (c)      During the existence of an Event of Default, such
Debtor agrees that, if such Debtor fails to perform under this Agreement, the
Secured Party may, but shall not be obligated to, after written request to such
Debtor to perform, perform such Debtor's obligations under this Agreement, and
any reasonable expenses incurred by the Secured Party in performing such
Debtor's obligations shall be paid by such Debtor.  Any such performance





                                      -6-
<PAGE>   94
by the Secured Party may be made by the Secured Party in reasonable reliance on
any statement, invoice, or claim, without inquiry into the validity or accuracy
thereof.  The amount and nature of any expense of the Secured Party hereunder
shall be conclusively established by a certificate of any officer of the
Secured Party absent manifest error.

                 (d)      Such Debtor irrevocably appoints the Secured Party as
such Debtor's attorney in fact, with full authority to act during the existence
of an Event of Default for such Debtor and in the name of such Debtor, to take
any action and execute any agreement which the Secured Party deems necessary or
advisable to accomplish the purposes of this Agreement, including the matters
that the Secured Party is expressly authorized to take pursuant to this
Agreement (including the matters described in paragraph (c) above), and
instituting proceedings the Secured Party deems necessary or desirable to
enforce the rights of the Secured Party with respect to this Agreement.
Provided, that the Secured Party shall first request in writing that such
Debtor take such actions and such Debtor shall, after reasonable opportunity,
have failed to do so.

                 (e)      The powers conferred on the Secured Party under this
Agreement are solely to protect the Secured Party's rights under this Agreement
and shall not impose any duty upon it to exercise any such powers.  Except as
elsewhere provided hereunder, the Secured Party shall have no duty as to any of
the Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to the Collateral.

         3.5     Insurance.  With respect to any casualty or condemnation to
the Collateral, all proceeds of such casualty or condemnation which are due to
such Debtor, including any property insurance proceeds, condemnation awards,
proceeds from actions, and any other proceeds, are assigned to the Secured
Party and shall be paid directly to the Secured Party for disposition in
accordance with Section 5.12 of the Credit Agreement.

         3.6     Value of Receivables.  Such Debtor shall use such Debtor's
commercially reasonable efforts to collect payments on the Receivables of such
Debtor when due.  Unless otherwise specified herein, such Debtor shall use
commercially reasonable efforts to perform such Debtor's obligations under each
contract giving rise to any Receivables of such Debtor.

Section 4.       General Remedies.  During the existence of an Event of
Default, the Secured Party may, at the Secured Party's option, exercise one or
more of the remedies specified elsewhere in this Agreement or the following
remedies:





                                      -7-
<PAGE>   95
         4.1     Interim Remedies.

                 (a)      To the extent permitted by law, the Secured Party may
exercise all the rights and remedies of a secured party under the UCC.

                 (b)      The Secured Party may prosecute actions in equity or
at law for the specific performance of any covenant or agreement herein
contained or in aid of the execution of any power herein granted or for the
enforcement of any other appropriate legal or equitable remedy.

                 (c)      The Secured Party may occupy any premises owned or
leased by any Debtor where any Collateral is assembled for a reasonable period
in order to effectuate the Secured Party's rights and remedies hereunder or
under law, without obligation to any Debtor with respect to such occupation.

         4.2     Remedies - Receivables.

                 (a)      During the existence of an Event of Default, the
Secured Party may establish Collateral Accounts for the purpose of collecting
the Receivables of such Debtor and holding the proceeds thereof, and may direct
such Debtor to instruct all account debtors and obligors on the Receivables of
such Debtor to make all payments on the Receivables of such Debtor directly to
the Secured Party for deposit into such Collateral Account.  After such
direction to such Debtor and until such direction has been rescinded (i) all
collections and proceeds of the Receivables of such Debtor shall be directed to
such Collateral Accounts, (ii) all proceeds of the Receivables of such Debtor
which may from time to time come into the possession of such Debtor shall be
held in trust for the Secured Party, segregated from the other funds of such
Debtor, and delivered immediately to the Secured Party in the form received
with any necessary endorsement for deposit into such Collateral Account, such
delivery in no event to be later than one Business Day after receipt thereof by
such Debtor, and (iii) such Debtor shall not adjust, settle, or compromise the
amount or payment of any Receivable of such Debtor, release wholly or partly
any account debtor or obligor for any Receivable of such Debtor, or allow any
credit or discount on any Receivable of such Debtor, without the advanced
written consent of the Secured Party.

                 (b)      In connection with the foregoing, the Secured Party
shall have the right at any time during the existence of an Event of Default to
take any of the following actions, in the Secured Party's own name or in the
name of such Debtor:  change the accounts which shall be the Collateral
Accounts for the Receivables of such Debtor; compromise or extend the time for
payment of the Receivables of such Debtor upon such terms as the Secured Party
may determine; endorse the name of such Debtor on checks, instruments, or other
evidences of payment on the Receivables of such Debtor; make written or verbal
requests for verification of amount owing on the Receivables of such Debtor
from





                                      -8-
<PAGE>   96
any Persons which the Secured Party believes are account debtors or obligors on
the Receivables of such Debtor; open mail addressed to such Debtor and, to the
extent of checks or other proceeds of the Receivables of such Debtor, dispose
of same in accordance with this Agreement; take action in the Secured Party's
name or such Debtor's name to enforce collection; and take all other action
necessary to carry out this Agreement and give effect to the Secured Party's
rights hereunder.  Costs and expenses incurred by the Secured Party in
collection and enforcement of the Receivables of such Debtor, including
attorneys' fees and out-of-pocket expenses, shall be reimbursed by such Debtor
to the Secured Party on demand.

         4.3     Foreclosure.

                 (a)      The Secured Party may foreclose on any Collateral in
any manner permitted by the courts of or in the State of Texas or the State in
which any Collateral is located.  If the Secured Party should institute a suit
for the collection of the Secured Obligations and for foreclosure under this
Agreement, the Secured Party may at any time before the entry of a final
judgment dismiss the same, and take any other action permitted by this
Agreement.

                 (b)      To the extent permitted by law, the Secured Party may
exercise all the foreclosure rights and remedies of a secured party under the
UCC.  In connection therewith, the Secured Party may sell any Collateral at
public or private sale, at the office of the Secured Party or elsewhere, for
cash or credit and upon written notice to such Debtor, such other terms as the
Secured Party deems commercially reasonable.  The Secured Party may sell any
Collateral at one or more sales, and the security interest granted hereunder
shall remain in effect as to the unsold portion of the Collateral.  Each Debtor
hereby deems ten days advance notice of the time and place of any public or
private sale reasonable notification, recognizing that if the Collateral is
perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, shorter notice may be reasonable.  The
Secured Party shall not be obligated to make any sale of Collateral regardless
of notice of sale having been given.  The Secured Party may adjourn any sale by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was adjourned.  In
the event that any sale hereunder is not completed or is defective in the
opinion of the Secured Party, the Secured Party shall have the right to cause
subsequent sales to be made hereunder.  Any statements of fact or other
recitals made in any bill of sale, assignment, or other document representing
any sale hereunder, including statements relating to the occurrence of an Event
of Default, acceleration of the Secured Obligations, notice of the sale, the
time, place, and terms of the sale, and other actions taken by the Secured
Party in relation to the sale may be conclusively relied upon by the purchaser
at any sale hereunder.  The Secured Party may delegate to any agent the
performance of any





                                      -9-
<PAGE>   97
acts in connection with any sale hereunder, including the sending of notices
and the conduct of the sale.

         4.4     Application of Proceeds.  Unless otherwise specified herein,
any cash proceeds received by the Secured Party from the sale of, collection
of, or other realization upon any part of the Collateral or any other amounts
received by the Secured Party hereunder may be, at the discretion of the
Secured Party (a) held by the Secured Party in one or more Collateral Accounts
as cash collateral for the Secured Obligations or (b) applied to the Secured
Obligations.  Amounts applied to the Secured Obligations shall be applied in
the following order:

                 First, to the payment of the costs and expenses of exercising
         the Secured Party's rights hereunder, whether expressly provided for
         herein or otherwise; and

                 Second, to the payment of the Secured Obligations in the order
         set forth in Section 6.9 of the Credit Agreement.

Any surplus cash collateral or cash proceeds held by the Secured Party after
payment in full of the Secured Obligations and the termination of all
commitments of the Secured Party to all Debtors shall be paid over by the
Secured Party to the Borrower for distribution to the Debtors entitled to
receive such surplus or to any other Persons that may be lawfully entitled to
receive such surplus.

         4.5     Waiver of Certain Rights.  To the full extent each Debtor may
do so, such Debtor shall not insist upon, plead, claim, or take advantage of
any law providing for any appraisement, valuation, stay, extension, or
redemption, and such Debtor hereby waives and releases the same, and all rights
to a marshaling of the assets of such Debtor, including the Collateral, or to a
sale in inverse order of alienation in the event of foreclosure of the liens
and security interests hereby created.  Such Debtor shall not assert any right
under any law pertaining to the marshaling of assets, sale in inverse order of
alienation, the administration of estates of decedents or other matters
whatever to defeat, reduce, or affect the right of the Secured Party under the
terms of this Agreement.

Section 5.       Miscellaneous.

         5.1     Choice of Law.  Except to the extent that the validity,
perfection, or effect of perfection or nonperfection of the security interests
created hereunder, or the remedies hereunder, in respect of any particular
Collateral are required to be governed by the laws of a jurisdiction other than
the State of Texas, this Agreement shall be subject to and construed and
enforced in accordance with the substantive laws of the State of Texas.

Agreement and the Credit Documents to which such Debtor is a party shall be in

forth below, or to such other address as shall be designated by such Debtor or

Agreement and the Credit Documents shall act as a waiver of the Secured Party's
rights thereunder.  The provisions of this Agreement may be waived or amended
only in a writing signed by the party against whom enforcement is sought.  This
Agreement shall bind and inure to the benefit of each Debtor and the Secured
Party and their respective successors and assigns.  Each Debtor may not assign

         5.4     Joinder.  Any present or future Subsidiary of the Borrower may

under the prior versions of this Agreement continue to secure such indebtedness
under this version of this Agreement without impairment or interruption.

BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

and agrees with the Secured Party as follows:

        3.1      Ownership. Such Pledgor owns all of its rights in the Pledged
Interests as set forth next to its name on Schedule I attached hereto, free and
clear of any liens, security interests, assignments, options, adverse claims,
restrictions, and other encumbrances whatsoever, and has the capacity to enter
into modifications of the Partnership Agreement applicable to the Pledged
Interests of such Pledgor without the consent of any other party other than the

interest, assignment, option, restriction, claim, or other encumbrance on or
against the Collateral, or lease, sell, or otherwise transfer any of its rights
in the Collateral, except (a) as permitted under the Credit Agreement, or (b)

                 (a)      Such Pledgor waives any provision of the Partnership
Agreement applicable to the Pledged Interests of such Pledgor prohibiting or
otherwise restricting the grant of the security interest hereunder. No consent

Party of its rights hereunder.

                 (b)      As of the date of this Agreement, the true and
correct name of such Pledgor as listed on such Pledgor's certificate of

Pledgor has not used and does not use any trade names other than those listed

appropriate office in lieu thereof.

         3.3     Priority. The security interest created by this Agreement is
first priority (except to the extent otherwise permitted in the Credit
Agreement), and each Pledgor shall preserve and maintain the status of such
security interest to the end that this Agreement shall remain a first priority
security interest in the Collateral.

         3.4     Value.

                 (a)      The Partnership Agreement applicable to the Pledged
Interests of such Pledgor has been duly authorized, executed, and delivered by
all parties thereto, and is in full force and effect, enforceable against all
parties thereto in accordance with its terms, subject to bankruptcy and general

Agreement has been made available for review by the Secured Party in connection
with the execution of this Agreement, and such Partnership Agreement has not
been amended, supplemented, or otherwise modified, or performance thereunder
waived.

<PAGE>   113
                 (b)      Such Pledgor shall furnish to the Secured Party
promptly upon the giving or receipt thereof, copies of all material notices,
requests, and other documents given to any party to the Partnership Agreement
applicable to the Pledged Interests of such Pledgor or received by such Pledgor
under such Partnership Agreement, and from time to time furnish to the Secured
Party such information and reports regarding the Collateral as the Secured
Party may reasonably request.

                 (c)      Such Pledgor has performed all of its obligations
under the Partnership Agreement applicable to the Pledged Interests of such
Pledgor, and has no liability with respect to any additional capital
contributions or other payment obligations thereunder. Such Pledgor shall use
its commercially reasonable efforts to maintain the Partnership Agreement
applicable to the Pledged Interests of such Pledgor in full force and effect.

                 (d)       Such Pledgor shall not without the advance written
consent of the Secured Party amend, supplement, or otherwise modify the
Partnership Agreement applicable to the Pledged Interests of such Pledgor as in
effect on the date hereof, waive performance under or terminate any provisions
thereof, or consent to any of those actions. Such Pledgor shall not take any
action in connection with such Partnership Agreement which materially impairs
the value of the rights of the Secured Party therein, or consent to any such
actions. If the Secured Party so requests, such Pledgor shall withhold from
taking any action under such Partnership Agreement, or shall take such actions
under such Partnership Agreement as the Secured Party may request.

                 (e)      Such Pledgor shall not initiate any remedies or take
any action to enforce such Pledgor's rights under the Partnership Agreement
applicable to the Pledged Interests of such Pledgor without giving the Secured
Party advance written notice of such Pledgor's intent to initiate such remedies
or take such actions thereunder and the opportunity to consult with such
Pledgor regarding such Pledgor's proposed actions.

         3.5     Use and Condition.

                 (a)      So long as no Default or Event of Default shall exist
and be continuing and until the Borrower has received notice from the Secured
Party pursuant to Section 4.1(c) of this Agreement (which notice the Borrower
shall promptly forward to the Pledgors), each Pledgor shall be entitled to
receive and retain any cash dividends or distributions distributed in respect
of the Pledged Interests of such Pledgor, provided that any: (i) non-cash
dividends, distributions, instruments, and other property received or otherwise
distributed in respect of or in substitution for any such Pledged Interests;
(ii) cash dividends and other distributions in connection with a partial or
total liquidation or dissolution of any Partnership or in





                                      -5-
<PAGE>   114
connection with a reduction of capital, capital surplus, or paid-in-surplus of
any Partnership; and (iii) cash distributed in respect of a redemption of
principal of, or in exchange for, any such Pledged Interests, shall be promptly
delivered to the Secured Party for disposition in accordance with Section 4.3
and shall, if received by any Pledgor, be received in trust for the benefit of
the Secured Party, be segregated from the other property or funds of such
Pledgor, and be promptly delivered to the Secured Party as Collateral in the
same form as so received, with any necessary endorsement.

                 (b)      With regard to the Pledged Interests of each Pledgor,
so long as no Default or Event of Default shall exist and be continuing and
until the Borrower has received notice from the Secured Party pursuant to
Section 4.1(d) of this Agreement (which notice the Borrower shall promptly
forward to the Pledgors), each Pledgor shall be entitled to exercise any voting
and other consensual rights pertaining to the Pledged Interests of such Pledgor
for any purpose not inconsistent with the terms of this Agreement. The Secured
Party shall execute and deliver (or cause to be executed and delivered) to such
Pledgor any instruments that such Pledgor may reasonably request to enable such
Pledgor to exercise the voting and other rights which it is entitled to
exercise hereunder and to receive the dividends, distributions, or interest
payments which it is authorized to receive and retain hereunder.

         3.6     Further Assurances.

                 (a)      Each Pledgor agrees that at any time such Pledgor
shall promptly execute and deliver all further agreements, and take all further
action, that may be necessary or that the Secured Party may reasonably request,
in order to further evidence the security interests granted or purported to be
granted hereunder and perfect and protect the same or to enable the Secured
Party to exercise and enforce its rights and remedies hereunder. Without
limiting the foregoing, each Pledgor shall at the Secured Party's reasonable
request: (i) mark conspicuously any tangible Collateral with a legend, in form
and substance satisfactory to the Secured Party, indicating that such
Collateral is subject to the security interest granted or purported to be
granted hereunder; and (ii) execute financing statements, amendments and
continuations of financing statements, and such other documents and agreements
as the Secured Party may reasonably request in order to perfect and preserve
the security interests granted or purported to be granted hereunder. Each
Pledgor shall furnish to the Secured Party from time to time any statements and
schedules further identifying and describing any of the Collateral and such
other reports in connection with the Collateral as the Secured Party may
reasonably request.

                 (b)      During the existence of an Event of Default, each
Pledgor agrees that, if such Pledgor fails to perform under this Agreement, the
Secured Party may, but shall not be obligated to, after written request to such
Pledgor to perform, perform such Pledgor's





                                      -6-
<PAGE>   115
obligations under this Agreement and any expenses reasonably incurred by the
Secured Party in performing such Pledgor's obligations shall be paid by such
Pledgor. Any such performance by the Secured Party may be made by the Secured
Party in reasonable reliance on any statement, invoice, or claim, without
inquiry into the validity or accuracy thereof. The amount and nature of any
expense of the Secured Party hereunder shall be conclusively established,
absent manifest error, by a certificate of any officer of the Secured Party.

                 (c)      Each Pledgor irrevocably appoints the Secured Party
as such Pledgor's attorney in fact, with full authority to act during the
existence of an Event of Default for such Pledgor and in the name of such
Pledgor, to take any action and execute any agreement which the Secured Party
deems necessary or advisable to accomplish the purposes of this Agreement,
including taking actions the Secured Party is expressly authorized to take
pursuant to this Agreement (such as the matters described in paragraph (b)
above), instituting proceedings the Secured Party deems necessary or desirable
to enforce the rights of the Secured Party with respect to this Agreement, and
taking actions with respect to receiving, endorsing, and collecting instruments
made payable to such Pledgor representing any dividend, interest payment, or
other distribution in respect of the Pledged Interests of such Pledgor and
giving full discharge for the same. Provided, that the Secured Party shall
first request in writing that such Pledgor take actions and such Pledgor shall,
after reasonable opportunity, have failed to do so.

                 (d)      The powers conferred on the Secured Party under this
Agreement are solely to protect its rights under this Agreement and shall not
impose any duty upon it to exercise any such powers. Except as elsewhere
provided hereunder, the Secured Party shall have no duty as to any of the
Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to the Collateral. The
Secured Party shall have no responsibility for (i) ascertaining or taking
action with respect to calls, conversions, exchanges, rights of first refusal,
or other matters relative to any Pledged Interests, whether or not the Secured
Party has or is deemed to have knowledge of such matters, or (ii) taking any
necessary steps to preserve rights against any parties with respect to any
Pledged Interests.

         3.7     Pledgor Remains Liable. Anything herein to the contrary
notwithstanding: (a) such Pledgor shall remain liable under the Partnership
Agreement applicable to the Pledged Interests of such Pledgor to the extent set
forth therein to perform such Pledgor's obligations thereunder to the same
extent as if this Agreement had not been executed; (b) the exercise by Secured
Party of any rights hereunder shall not release such Pledgor from any
obligations under such Partnership Agreement; and (c) Secured Party shall not
have any obligation under such Partnership Agreement by reason of this
Agreement, nor shall Secured Party be obligated to perform or fulfill any of
the obligations of such Pledgor thereunder,





                                      -7-
<PAGE>   116
including any obligation to make any inquiry as to the nature or sufficiency of
any payment such Pledgor may be entitled to receive thereunder, to present or
file any claim, or to take any action to collect or enforce any claim for
payment thereunder.

Section 4.       Remedies. During the continuation of any Event of Default:

        4.1      Interim Remedies.

                 (a)      The Secured Party may exercise all the rights and
remedies of a secured party under the UCC.

                 (b)      The Secured Party may prosecute actions in equity or
at law for the specific performance of any covenant or agreement herein
contained or in aid of the execution of any power herein granted or for the
enforcement of any other appropriate legal or equitable remedy.

                 (c)      During the continuance of an Event of Default,
following written notice to the Borrower (which notice the Borrower shall
promptly forward to the Pledgors) and to the extent specified in such written
notice, all rights of the Pledgors to receive cash dividends or distributions
shall cease, and all such rights shall thereupon become vested in the Secured
Party who shall thereupon have the sole right to receive such cash dividends.
All cash dividends or distributions received by any Pledgor in violation of the
foregoing shall be received in trust for the benefit of the Secured Party,
shall be segregated from other funds of such Pledgor, and shall be promptly
paid over to the Secured Party to be held as Pledged Interests in the same form
as so received (with any necessary endorsement).

                 (d)      During the continuance of an Event of Default,
following written notice to the Borrower (which notice the Borrower shall
promptly forward to the Pledgors) and to the extent specified in such written
notice, all rights of the Pledgors to exercise the voting and other consensual
rights which they would otherwise be entitled to exercise under the Partnership
Agreements and pursuant to this Agreement shall cease, and all such rights
shall thereupon become vested in the Secured Party who shall thereupon have the
sole right to exercise such voting and other consensual rights, and the Secured
Party may instruct each Pledgor to take or not take action under the applicable
Partnership Agreements. Following such notice from the Secured Party, each
Pledgor authorizes all other parties to the Partnership Agreement applicable to
the Pledged Interests of such Pledgor to follow the instructions of the Secured
Party and ignore the instructions of such Pledgor with respect to such
Pledgor's rights under such Partnership Agreement.

                 (e)      During the continuance of an Event of Default,
following written





                                      -8-
<PAGE>   117
notice to the Borrower (which notice the Borrower shall promptly forward to the
Pledgors) and to the extent specified in such written notice, the Secured Party
shall have the right, without further notice to any Pledgor, to transfer or to
register, in the name of the Secured Party or any of its nominees, any of the
Pledged Interests.

                 (f)      The Secured Party may require any Pledgor to promptly
assemble any tangible Collateral of such Pledgor and make it available to the
Secured Party at a place to be designated by the Secured Party. The Secured
Party may occupy any premises owned or leased by any Pledgor where the
Collateral is assembled for a reasonable period in order to effectuate its
rights and remedies hereunder or under law, without obligation to such Pledgor
with respect to such occupation. The Secured Party shall have no obligation to
take any action to assemble or otherwise take control of the Collateral,
whether for the purposes of sale or otherwise.

                 (g)      The Secured Party may take any action permitted under
the Credit Agreement or other Credit Documents, including declaring the unpaid
portion of the Secured Obligations to be immediately due and payable under the
terms of the Credit Agreement.

         4.2     Foreclosure.

                 (a)      The Secured Party may foreclose on the Collateral in
any manner permitted by the courts of or in the State of Texas. If the Secured
Party should institute a suit for the collection of the Secured Obligations and
for the foreclosure of this Agreement, the Secured Party may at any time before
the entry of a final judgment dismiss the same, and take any other action
permitted by this Agreement.

                 (b)      The Secured Party may exercise all the rights and
remedies of a secured party under the UCC, including foreclosure.

                          (i)     If, in the opinion of the Secured Party,
there is any question that a public or semipublic sale or distribution of any
Collateral will violate any state or federal securities law, the Secured Party
in its discretion (A) may offer and sell the Pledged Interests privately to
purchasers who will agree to take them for investment purposes and not with a
view to distribution, or (B) may, if lawful, sell such securities in an
intrastate offering under Section 3(a)(11) of the Securities Act of 1933, as
amended, and no sale so made in good faith by the Secured Party shall be deemed
to be not "commercially reasonable" because so made. Each Pledgor shall
cooperate fully with Secured Party in all respects in selling or realizing upon
all or any part of the Collateral. In addition, each Pledgor shall fully comply





                                      -9-
<PAGE>   118
with the securities laws of the United States, the State of Texas, and other
states and take such actions as may be necessary to permit the Secured Party to
sell or otherwise dispose of any partnership interests pledged hereunder in
compliance with such laws; provided that this Section 4.2(b)(i) shall not
require any Pledgor to file a registration statement with respect to such
partnership interests.

                          (ii)    The Secured Party may sell, after notice to
the Pledgor, any Collateral at public or private sale, at the office of the
Secured Party or elsewhere, for cash or credit and upon such other terms as the
Secured Party deems commercially reasonable. The Secured Party may sell any
Collateral at one or more sales, and the security interest granted hereunder
shall remain in effect as to the unsold portion of the Collateral. Each Pledgor
hereby deems ten days advance notice of the time and place of any public or
private sale reasonable notification, recognizing that if the Collateral is
perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, shorter notice may be reasonable. The
Secured Party shall not be obligated to make any sale of Collateral regardless
of notice of sale having been given. The Secured Party may adjourn any sale by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was adjourned. In the
event that any sale hereunder is not completed or is defective in the opinion
of the Secured Party, the Secured Party shall have the right to cause
subsequent sales to be made hereunder. Any statements of fact or other recitals
made in any bill of sale, assignment, or other document representing any sale
hereunder, including statements relating to the occurrence of an Event of
Default, acceleration of the Secured Obligations, notice of the sale, the time,
place, and terms of the sale, and other actions taken by the Secured Party in
relation to the sale shall be conclusive evidence of the truth of the matters
so stated. The Secured Party may delegate to any agent the performance of any
acts in connection with any sale hereunder, including the sending of notices
and the conduct of the sale.

         4.3     Application of Proceeds. Unless otherwise specified herein,
any cash proceeds received by the Secured Party from the sale of, collection
of, or other realization upon any part of the Collateral shall be applied by
the Secured Party in accordance with and in the manner specified by Section 6.9
of the Credit Agreement.

         4.4     Waiver of Certain Rights. To the full extent each Pledgor may
do so, no Pledgor shall insist upon, plead, claim, or take advantage of any law
providing for any appraisement, valuation, stay, extension, or redemption, and
each Pledgor hereby waives and releases the same, and all rights to a
marshaling of the assets of such Pledgor, including the Collateral, or to a
sale in inverse order of alienation in the event of foreclosure of the liens
and security interests hereby created. No Pledgor shall assert any right under
any law pertaining to the marshaling of assets, sale in inverse order of
alienation, the administration





                                      -10-
<PAGE>   119
of estates of decedents or other matters whatever to defeat, reduce, or affect
the right of the Secured Party under the terms of this Agreement.

Section 5.       Miscellaneous.

        5.1      Notices. All notices and other communications from the Secured
Party to any Pledgor provided for in this Agreement shall be delivered or
transmitted to the Borrower, and shall be deemed delivered to any such Pledgor
upon delivery to the Borrower. All notices and other communications between the
parties provided for in this Agreement shall be delivered or transmitted as
provided in the Credit Agreement to the applicable address set forth therein.

        5.2      General. This miscellaneous provisions contained in Article 8
of the Credit Agreement are incorporated herein as if fully set forth herein.
This Agreement may be executed in multiple counterparts each of which shall
constitute one and the same agreement.

        5.3      Amendment and Restatement. This Agreement represents an
amendment, restatement, and consolidation of the Pledge Agreements, each dated
as of January 30, 1998, made by certain of the Pledgors in favor of NationsBank
of Texas, N.A., predecessor in interest to NationsBank, N.A., as Secured Party,
and all previous versions are deemed replaced hereby. The indebtedness secured
under the prior versions of this Agreement continues to be secured under this
version of this Agreement and the execution of this Agreement does not indicate
a payment, satisfaction, novation, or discharge thereof. All security interests
under the prior versions of this Agreement continue to secure such indebtedness
under this version of this Agreement without impairment or interruption.

THIS WRITTEN AGREEMENT REPRESENTS THE FINAL AGREEMENT AMONG THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.
