ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On April 29, 1999, Integrated Electrical Services, Inc. (the "Company")
consummated the acquisition of all of the issued and outstanding capital stock
of Putzel Acquisition Corporation, Putzel Electrical Contractors, Inc. and
Morris Putzel, the sole stockholder (collectively, the "Significant
Acquisition"). The Significant Acquisition performs electrical contracting in
the Southeast United States. The consideration paid by the Company for the
Significant Acquisition was determined through negotiations between
representatives of the Company and the owners of the Significant Acquisition and
consisted of an aggregate of 589,060 shares of common stock of the Company and
approximately $10.5 million in cash. The cash portion of the consideration paid
for the Significant Acquisition was funded through proceeds from the Company's
offering of $150.0 million Senior Subordinated Notes on January 25, 1999. The
Company intends to continue using the assets of the Significant Acquisition in
the electrical contracting business.

ITEM 5.  OTHER EVENTS

         Integrated Electrical Services, Inc., a Delaware corporation (the
"Company") is a leading national provider and consolidator of electrical
contracting and maintenance services, focusing primarily on the commercial,
industrial, residential, powerline and data communication markets. In connection
with its business acquisitions, the Company plans to offer shares of the
Company's Common Stock, $.01 par value per share (the "Common Stock") pursuant
to its Registration Statement on Form S-1 (Registration No. 333-45479). In order
to comply with the disclosure requirements of the Securities and Exchange
Commission regarding the financial statements of businesses acquired or to be
acquired, the Company is filing this Current Report containing the following
audited and pro forma financial statements.

         (a)      Pro Forma Financial Information
                  See Pages 2 through 7

                      INTEGRATED ELECTRICAL SERVICES, INC.

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS
                              BASIS OF PRESENTATION

         The unaudited pro forma balance sheet reflects the acquisitions by
Integrated Electrical Services, Inc. ("IES"), of Rockwell Electric, Inc., Canova
Electrical Contracting, Inc. and Linemen, Inc. dba California Communications
(collectively, the "Acquisitions") which were acquired subsequent to December
31, 1998, as if they had occurred on December 31, 1998. The unaudited pro forma
statements of operations present the statement of operations data give effect to
the Acquisitions and the related pro forma adjustments as if they had occurred
on October 1, 1997.

         IES has analyzed the savings that it expects to realize from reductions
in salaries, bonuses and certain benefits to the owners. To the extent the
owners of the Acquisitions have contractually agreed to changes in salary,
bonuses, benefits and lease payments, these changes have been reflected in the
unaudited pro forma combined statement of operations.

         Certain 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 these dates and are not necessarily
representative of IES's combined financial position or results of operations for
any future period. Since the acquired entities were not under common control or
management prior to their acquisitions by IES, historical combined results may
not be comparable to, or indicative of, future performance. The unaudited pro
forma financial statements should be read in conjunction with the historical
consolidated financial statements and notes thereto included in the company's
Annual Report for the year ended September 30, 1998 filed on Form 10-K. See also
"Risk Factors" included elsewhere therein.

                             ROCKWELL ELECTRIC, INC.
                          NOTES TO FINANCIAL STATEMENTS
                                NOVEMBER 30, 1998

1.   Organization and description of business:

        Rockwell Electric, Inc. (the Company) is engaged primarily in systems
        integration and electrical contracting. The Company was incorporated on
        January 3, 1979, in the state of California. The Company's operations
        are primarily conducted in Southern California and involve
        prime-contracts, sub-contracts and technical service for electrical
        contracts, SCADA (Supervisory Control and Data Acquisition) systems and
        the fabrication of instrumentation and control panels. The primary
        market for the Company is the water and waste-water industry with
        emphasis on public works projects.

2.   Summary of significant accounting policies:

     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 the reported amounts of revenues and expenses
        during the reporting period. Actual results could differ from those
        estimates.

     Revenue and cost recognition

         The Company recognizes revenues from long-term contracts on the
         percentage-of-completion method. Under this method, the completion
         percentage is measured by the proportion of cost incurred to date to
         total estimated cost for each contract. This method is used because
         management believes the cost-to-cost method 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 in the near term.

         Contract costs include all direct material and labor costs and those
         indirect costs related to contract performance, such as indirect labor,
         supplies, insurance, equipment 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.

         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.

     Concentrations of credit risk

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

         The Company maintains cash balances at three financial institutions.
         Accounts at these institutions are insured by the Federal Deposit
         Insurance Corporation up to $100,000. At times, the balances in the
         Company's accounts may exceed this limit. The Company has not
         experienced any losses in such accounts. The Company believes it is not
         exposed to any significant credit risk on cash.

         The Company grants credit, generally without collateral, to its
         customers, which include national industrial and commercial
         enterprises, regional public agencies, and various general contractors.
         Management believes that its contract acceptance, billing and
         collection policies are adequate to minimize potential credit risk.

     Inventories

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

     Property and equipment

         Property and equipment are stated at cost. Depreciation is provided on
         a straight-line basis over the estimated useful lives of the assets (3
         to 7 years). 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 over its life. 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 statement of operations.

         At November 30, 1998, property and equipment consist of the following:

     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. Deferred taxes are recognized for differences between
         the bases of assets and liabilities for financial statement and income
         tax purposes. These differences relate primarily to the difference
         between the bases of long-term contracts and depreciable assets. The
         deferred tax assets and liabilities 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.
         Deferred taxes also are recognized for operating losses and tax credits
         that are available to offset future taxable income and income taxes.

         For income tax purposes, the Company uses the accrual basis and
         percentage-of-completion methods of accounting, depending upon the
         contract classification. Construction contracts are accounted for using
         the accrual basis method. Non-construction contracts are accounted for
         using the percentage-of-completion method. Under the accrual method,
         income is recognized upon the billing of revenues and expenses are
         generally deductible when incurred.

         The Company may also be subject to the alternative minimum tax (AMT).
         AMT is calculated based on the percentage-of-completion method at lower
         tax rates than the regular tax. The excess of AMT over regular tax is
         added to the regular tax. This excess is carried over to future years
         as a credit against regular tax until it is fully utilized. The credit
         cannot reduce the regular tax below AMT in any year.

     Fair value of financial instruments

         The Company's financial instruments consist of cash, accounts
         receivable, a line of credit, accounts payable and debt. The Company
         believes that the carrying values of these instruments on the
         accompanying balance sheet approximate their fair values.

3. Cost and estimated earnings on uncompleted contracts:

         At November 30, 1998, the Company had available federal and state
         alternative minimum tax credits of approximately $58,500 and $37,500,
         respectively, available to offset future income tax liabilities.

7.   Operating lease commitments:

         In November, 1994, the Company entered into a noncancellable operating
         lease agreement with its majority stockholder to lease a facility
         constructed and owned by the majority stockholder. The lease term began
         on December 1, 1994 and expires on November 30, 2004. The lease
         contains three (3) five-year renewal options under the same terms and
         conditions. The lease provides for adjustments in the annual rents on
         each anniversary date of the lease, based on an inflation index,
         limited to minimum and maximum increases of 3% and 8%, respectively.
         The Company is also responsible for the payment of property taxes,
         insurance, repairs and maintenance under the terms of the lease
         agreement.

         Effective June 1, 1997, the majority stockholder completed construction
         of additional office space at the premises. The original lease
         agreement was amended to increase the monthly lease payment, as of June
         1, 1997, for the additional lease space. All of the other terms and
         conditions of the original lease agreement remain unchanged.

         The monthly lease payments were $7,375 for the year ended November 30,
         1998. Rent expense under this lease for the year ended November 30,
         1998 was $88,500. Property taxes paid under the agreement were $6,720.

         Future minimum rental payments under the operating lease are as
         follows:

</TABLE>

8.   Benefit plans:

         On April 1, 1993, the Company established a salary reduction/profit
         sharing plan under Section 401(k) of the Internal Revenue Code that
         covers all eligible employees. The plan provides for the Company to
         match voluntary employee contributions at a discretionary rate up to
         100%. The maximum employee contribution the Company will match is 100%
         which equates to a maximum of 15% of annual compensation. Such matching
         rate can be changed at the Company's discretion. All contributions by
         the Company are funded currently and vest over 6 years. All employee
         contributions are immediately vested. Company matching contributions to
         the plan were $70,167 for the year ended November 30, 1998.

9.   Stockholders' agreement:

         The Company and the stockholders entered into an agreement on November
         15, 1996, which prohibits any stockholders from transferring, assigning
         or encumbering their stock, without prior written consent of the
         Company and the other stockholder. In addition, the Company is
         obligated to purchase the shares of a stockholder in the event of his
         death, termination or disability, in the event the remaining
         stockholder does not do so. The methodology for determining the
         purchase price is set forth in the agreement.

10.  Major customers and risk concentration:

         The Company's contract revenues are highly concentrated with three
         individual customers. These customers accounted for approximately 
         $3,982,000 or 44% of contract revenues for the year ended November 30,
         1998. The associated accounts receivable from these customers total
         approximately $536,000 or 28% of total accounts receivable at November
         30, 1998. The loss of a significant customer could have a material
         impact on the Company's future earnings results. The Company has
         recorded an allowance for doubtful accounts of $11,151 as of November
         30, 1998. Management believes that this allowance is adequate.

11.  Commitments and contingencies:

         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 operation.

                                       17

12.  Subsequent events:

         On January 27, 1999, the Company completed the sale of all of its
         outstanding common stock to Integrated Electrical Services, Inc.

         On March 1, 1999, the Company entered into a noncancellable operating
         lease agreement for additional office space. The lease term is for
         seven years commencing June 1, 1999 and ending May 31, 2006. The lease
         provides for base rent of $9,632 per month for the first year of
         tenancy, with an increase of 3% at the beginning of each year
         thereafter. The Company will also be responsible for a proportionate
         share of common area expenses.

         Future minimum rental payments under the operating lease agreement are
         as follows:

                          NOTES TO FINANCIAL STATEMENTS
                                DECEMBER 31, 1998


NOTE 1   ORGANIZATION AND DESCRIPTION OF BUSINESS

         The Company is engaged in the business of providing electrical
         contracting services on various commercial, institutional, industrial
         and multi-family residential projects located primarily in Western
         Pennsylvania. The Company began operations in 1972 and conducted
         business as a sole proprietorship until January 10, 1989, when it was
         incorporated under the laws of the Commonwealth of Pennsylvania


NOTE 2   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         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 the reported amounts of revenues
         and expenses during the reporting period. Actual results could differ
         from those estimates.

         REVENUE AND COST RECOGNITION

         Revenues are recognized on the percentage-of-completion method,
         measured by the costs incurred to date to the estimated total costs for
         each contract. Contract revenue earned is the amount of direct costs
         incurred plus the amount of gross profit recognized based on the extent
         of progress toward completion.

         Contract costs include all direct costs and job related overhead.
         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 condition, and estimated profitability may result in
         revisions to costs and income and are recognized in the period in which
         the revisions are determined. Because of inherent uncertainties in
         estimating costs and revenues, it is at least reasonably possible that
         the estimates used will change in the near term.

         CONCENTRATION OF CREDIT RISK
         
         The Company maintains cash balances with high quality financial
         institutions. At times such cash balances may be in excess of the FDIC
         insurance limit.

         The Company's revenues are highly concentrated with a few customers.
         Contract revenues from three customers in 1998 represented
         approximately 75% of total contract revenues for the year ended
         December 31, 1998. The contract accounts receivable from these
         customers were $324,670 as of December 31, 1998. The loss of a
         significant customer could have a material impact on the Company's
         future earnings results.

         The Company has recorded an allowance for doubtful accounts of
         approximately $10,000 as of December 31, 1998. Management believes that
         this allowance is adequate.

          FAIR VALUE OF FINANCIAL INSTRUMENTS

         The Company's financial instruments consist of cash, accounts
         receivable, accounts payable and notes payable. Estimates of the fair
         value of these instruments are based on interest rates available to the
         Company. At December 31, 1998, the carrying value of the Company's
         financial instruments approximated fair value.

          
         INCOME TAXES

         The Company has elected S corporation status for federal and state
         income tax purposes whereby the Company's taxable income and any tax
         credits resulting from operating losses will be included in the
         individual income tax return of its stockholder. Therefore, no
         provision for income taxes is included in these financial statements.

                     ---------------------------------------

                          NOTES TO FINANCIAL STATEMENTS
                  DECEMBER 31, 1998, MARCH 31, 1998 (UNAUDITED)
                         AND MARCH 31, 1999 (UNAUDITED)

1.   ORGANIZATION AND DESCRIPTION OF BUSINESS:

LINEMEN, INC dba CALIFORNIA COMMUNICATIONS (the Company) is engaged in the
installation of copper, coaxial and fiber-optic communications cable. The work
is performed under fixed-price and time-and-equipment contracts. The Company was
incorporated on August 13, 1996, in the state of California.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM FINANCIAL STATEMENTS

The accompanying interim financial statements and related disclosures for the
three months ended March 31, 1998 and 1999, have not been audited by independent
accountants. However, the financial statements for all interim periods have been
prepared in conformity with the accounting principles stated in the audited
financial statements for the year ended December 31, 1998, and include all
adjustments (which were of a normal, recurring nature) which, in the opinion of
management, are necessary to present fairly the financial position of the
Company and the results of operations and cash flows for each of the periods
presented. The operating results for the interim periods presented are not
necessarily indicative of results for the full year.

FINANCIAL STATEMENT CLASSIFICATION

In accordance with normal practice in the construction industry, the Company
includes in current assets and liabilities amounts realizable and payable over a
period in excess of one year. Consistent with this practice, asset and liability
accounts relating to construction contracts, including related deferred income
taxes, are classified as current. The lives of contracts entered into by the
Company generally range from one to two months.

REVENUE AND COST RECOGNITION

The Company recognizes revenues from long-term construction contracts on the
percentage-of-completion method. Under this method, the completion percentage is
measured by the proportion of costs incurred to date to total estimated costs
for each contract. However, no gross profit is recognized on contracts that are
less than ten percent complete. This method is used because management believes
the cost-to-cost method to be the best available measure of progress on the
contracts. Because of inherent uncertainties in estimating cost, it is at least
reasonably possible that the estimates used will change within the near term.


                                       33
<PAGE>   35


Contract costs include all direct material, labor and subcontract 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
revenue when realization is probable and the amount can be reliably estimated.
Contracts are considered completed when all costs except insignificant items
have been incurred and the owner has accepted the project.

The asset, "Costs and estimated gross profit in excess of billings on contracts
in progress," represents revenue recognized in excess of amounts billed.

INVENTORY

Inventory represents construction materials and supplies not allocated to
specific construction projects. Inventory is valued at lower of cost or market
based on the first-in, first-out method.

LEASEHOLD IMPROVEMENTS AND EQUIPMENT

Leasehold improvements and equipment, carried at cost, is depreciated over the
estimated useful life of the related asset. Depreciation is computed
substantially on the straight-line method for financial statement purposes and
accelerated methods for income tax reporting purposes. Transportation and
construction equipment are depreciated over 5 years. Office equipment is
depreciated between 3 and 7 years. Leasehold improvements are depreciated over
15 years.

At December 31, 1998, leasehold improvements and equipment consisted of:

</TABLE>

Depreciation charged to general and administrative expenses amounted to $120,567
for the year ended December 31, 1998.

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.
Deferred taxes are recognized for differences between the bases of assets and
liabilities for financial statement and income tax purposes. The differences
relate primarily to the difference between the bases of long-term


                                       34
<PAGE>   36


contracts and depreciable assets. The deferred tax assets and liabilities
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. Deferred taxes also are recognized for operating losses and tax credits
that are available to offset future taxable income and income taxes.

For income tax purposes, the Company reports income on the cash method of
accounting. Under this method, billings and costs are accumulated during the
period of construction, but billings are not recorded until received and costs
are not recorded until paid.

The Company may also be subject to the alternative minimum tax (AMT). AMT is
calculated based on the percentage-of-completion method at lower tax rates than
the regular tax. The excess of AMT over regular tax is added to the regular tax.
This excess is carried over to future years as a credit against regular tax
until it is fully utilized. The credit cannot reduce the regular tax below AMT
in any 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
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

CONCENTRATIONS OF RISK

The Company's contracts receivable and contract revenue are highly concentrated
in two customers. These customers account for approximately 98% of contracts
receivable in the year ended December 31, 1998. The associated contract revenue
from these customers represented approximately 95% of total contract revenue at
December 31, 1998. The loss of either of these significant customers could have
a material impact on the Company's future earnings results.

The Company grants credit to its customers and the company's management believes
that its contract acceptance, billing, and collection policies are adequate to
minimize potential credit risk.

The Company maintains its demand deposits in commercial banks with Federal
Deposit Insurance Corporation limits of $100,000 per bank.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company's financial instruments consist of cash, accounts receivable and
accounts payable. Estimates of the fair value of these instruments are based on
interest rates available to the Company. At December 31, 1998, the carrying
value of the Company's financial instruments approximated the fair value.

a general partner. Equipment rent expensed to contract costs amounted to $39,682
for the year ended December 31, 1998 of which $17,250 is included in accounts
payable.

AGREEMENT AND PLAN OF MERGER

         AGREEMENT AND PLAN OF MERGER ("Agreement") dated as of April 29, 1999
among Integrated Electrical Services, Inc., a Delaware corporation ("IES"),
Putzel Acquisition Corporation, a Delaware corporation and a wholly owned
subsidiary of IES ("Acquisition"), Putzel Electrical Contractors, Inc., a
Georgia corporation ("Company"), and Morris Purcel, who is the sole stockholder
of the Company (the "Company Stockholder").

                                    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 Stockholder desires to enter into an exchange with
IES of all of the issued and outstanding shares of capital stock of the Company,
free and clear of all liens, and the Company Stockholder agrees to be bound by a
covenant not to compete;

         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;

         WHEREAS, IES, the Company and the Company Stockholder intends the
combination of IES and the Company to qualify as a tax-free reorganization under
the provisions of Section 368 of the Internal Revenue Code of 1986, as amended
(the "Code"), and the regulations thereunder;

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

                                    ARTICLE I

                                   THE MERGER

THE MERGER. (a) At the closing of the transactions contemplated by this
Agreement (the "Closing") and after delivery of the documents listed in Section
1.6, at the Effective Time (as hereinafter defined) the Company shall be merged
(the "Merger") with and into Acquisition in accordance with the General
Corporation Law of the State of Delaware ("Delaware Law") and the Georgia
Business Corporation Code of the State of Georgia ("Georgia Law"), whereupon the
separate existence of the Company shall cease, and Acquisition 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 a certificate of merger (the
"Certificates of Merger") with the Delaware Secretary of State and the Georgia
Secretary of State and make all other filings or recordings required by Delaware
Law and Georgia Law in connection with the Merger. The Merger shall become
effective at such time (the "Effective Time") as the Certificates of Merger are
duly filed with the Delaware Secretary of State and the Georgia Secretary of
State (or at such later time as may be agreed in writing by the parties hereto
and specified in the Certificates of Merger).

<PAGE>   7

         (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 Delaware Law.

         (d) The Closing of the transactions shall take place at the offices of
IES in Houston, Texas, at 9:00 a.m., on April 29, 1999.

         (e) The Certificates of Merger shall include a provision for changing
the name of the Surviving Corporation to Putzel Electrical Contractors, Inc., if
such name is available and can be obtained from the respective states.

CONVERSION OF SHARES.   At the Effective Time:

         (a) the shares of common stock Class "A", $100.00 par value, and the
shares of common stock Class "B", no 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 589,060 shares of
common stock, $0.01 par value, of IES ("IES Common Stock") and cash
consideration of $10,500,000 (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.

SURRENDER AND PAYMENT. At the Effective Time, the Company Stockholder 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 to the Company
Stockholder in accordance with the written instructions provided in Schedule
3.2(a). The Certificates will be duly endorsed (or accompanied by a duly
executed stock power), with the signature of the Company Stockholder, if not
present at the Closing of the Merger, guaranteed by a commercial bank or by a
member firm of the New York Stock Exchange.

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 10.15) 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, 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.

         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 Certificate as contemplated by this Article I.

            REPRESENTATIONS AND WARRANTIES OF THE COMPANY STOCKHOLDER

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

         SECTION 3.1. ORGANIZATION AND QUALIFICATION. The Company 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 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 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 10.15). Schedule 3.1 contains a list of all
jurisdictions in which the Company 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 Company in each instance including
any amendments thereto, as currently in effect.

         SECTION 3.2. CAPITALIZATION; OWNERSHIP. (a) The authorized capital
stock of the Company consists of 500 shares of Class "A" common stock and 1000
shares of Class "B"common stock, of which 250 shares of Class "A" common stock
and 298 shares of Class "B" common stock 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 Stockholder owns the number of shares of
Company Common Stock set forth on Schedule 3.2(a) attached hereto, free and
clear of all Liens (as defined in Section 10.15). 


                                     - 5 -
<PAGE>   11


The Company Stockholder has full legal right, power and authority to exchange,
assign and transfer or cause to be exchanged, assigned or transferred his 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. The Company Stockholder does not or will not have appraisal or
similar rights as a result of the consummation of the transactions contemplated
by this Agreement.

         (b) The Company has no subsidiaries.

         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 Stockholder and the
Board of Directors of the Company have by unanimous written consent (a)
determined that participating in the Merger is in the best interests of the
Company and its stockholders and (b) approved this Agreement and the Merger. No
other corporate proceedings on the part of the Company or the Company
Stockholder are necessary to authorize the execution and delivery of this
Agreement or the consummation by the Company and the Company Stockholder of the
transactions contemplated hereby. This Agreement has been duly authorized,
executed, and delivered by the Company and the Company Stockholder and
constitutes the valid and binding obligation of the Company and the Company
Stockholder, enforceable against the Company and the Company Stockholder in
accordance with its terms.

         SECTION 3.4. CONSENTS AND APPROVALS; NO VIOLATION. Neither the
execution and delivery of this Agreement by the Company or the Company
Stockholder, nor the consummation by the Company or the Company Stockholder 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 Authority (as defined in Section 10.15), except (i) the filing of
the Certificates of Merger in accordance with Delaware Law and Georgia Law, (ii)
any regulatory approvals or routine governmental consents normally acquired
after the consummation of transactions such as transactions of the nature
contemplated by this Agreement, which consents and approvals are listed on
Schedule 3.4,or or (iii) 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, a Company
Material Adverse Effect or prevent or delay, in any material respect, the
consummation of the transactions contemplated by this Agreement; (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 contract,
commitment or similar agreement to which the Company is a party, except (i) as
set forth on Schedule 3.4 or (ii) 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, a Company 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
3.4(a), violate any order, writ, injunction, decree, statute, rule, or
regulation applicable to the Company or any of their assets, except for
violations which are not reasonably expected to have, individually or in the
aggregate, a Company Material Adverse Effect or prevent or delay, in any
material respect, the consummation of the transactions contemplated by this
Agreement. The Company is not, and the consummation of the transactions
contemplated by this Agreement will not result, in violation of its Articles of
Incorporation or Bylaws.

         SECTION 3.5. AFFILIATE RELATIONSHIPS. Except as set forth on Schedule
3.5, neither the Company Stockholder nor any affiliate of the Company
Stockholder, and no director, officer, employee or agent of or consultant to the
Company, owns, directly or indirectly, in whole or in part, any property, assets
or right, tangible or intangible, which is associated with any property, asset
or right owned by the Company or which the Company is operating or using or the
use of which is necessary for its business. Also included in Schedule 3.5 is
disclosure of any relationships which the Company Stockholder has, or any
director, officer, employee, or agent of or consultant to the Company has, with
the Company or any other corporation, partnership, firm, association or business
organization, entity or enterprise which is a competitor, potential competitor,
supplier or customer of the Company. The Persons named on Schedule 3.5 are the
only Persons who may be deemed affiliates of the Company under Rule 145 of the
Securities Act of 1933, as amended (the "1933 Act").

         SECTION 3.6. FINANCIAL STATEMENTS. Attached as Schedule 3.6 are (a) the
audited consolidated balance sheet, statement of income and statement of cash
flows of the Company as of and for the years ended December 31, 1996 and 1997
and the audited consolidated balance sheet, statement of income and statement of
cash flows of the Company as of and for the year ended December 31, 1998
(collectively, the "Company Financial Statements"). The Company Financial
Statements present fairly the consolidated financial position, results of
operations, and changes in financial position of the Company as of the
respective dates or for the respective periods to which they apply in accordance

favorable determination letter from the Internal Revenue Service with respect to
each Company Benefit Plan that is intended to be qualified under Section 401(a)

         (b) All Company Benefit Plans are and have been administered in
compliance with their terms and all applicable laws, including, without
limitation, ERISA and the Code, 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 Stockholder's Knowledge, threatened investigations by any
governmental entity, termination proceedings, or other suits or proceedings
against or involving any Company Benefit Plan. All such plans that are intended

         SECTION 3.22. TAX TREATMENT. Neither the Company nor, to the Company
Stockholder's Knowledge, any of its affiliates has taken, has agreed or failed
to take, or intends to take any action or has any knowledge of any fact or
circumstance that would prevent the Merger from qualifying as a reorganization
within the meaning of Section 368 of the Code (a "368 Reorganization").

         SECTION 3.23. SECTION 368(a)(2)(D) REPRESENTATIONS. The Company and the
Company Stockholder hereby represent and warrant the following to be true and
correct as of the Effective Time:

         (a) The fair market value of the IES Common Stock and other
consideration received by the Company Stockholder will be approximately equal to
the fair market value of the Company Common Stock surrendered in the exchange.


                                     - 14 -
<PAGE>   20


         (b) There is no plan or intention of the Company Stockholder to have
IES redeem, or have a party related to IES acquire, shares of IES Common Stock
received in the Merger which would reduce the Company Stockholder's ownership of
a number of shares of IES Common Stock received in the Merger to a number of
shares having a value, as of the date of the Merger, of less than 40% of the sum
of (i) the value at the Effective Time of all the Company Common Stock held
immediately prior to the Merger by the Company Stockholder and (ii) the value at
the Effective Time of any other instruments (such as debt of the Company which
is guaranteed by the Company Stockholder) which are classified for federal
income tax purposes as stock of the Company (collectively, "Shares") and which
are held immediately prior to the Merger by the Company Stockholder. For
purposes of this representation, Shares outstanding immediately prior to the
Merger include Shares redeemed prior to the Merger by reason of this Agreement
or otherwise as part of the Merger, and the value of all Shares outstanding
immediately prior to the Merger shall be determined with regard to any
extraordinary distributions (i.e., distributions with respect to Shares other
than regular, normal dividends) by the Company by reason of this Agreement or
otherwise as part of the Merger. For purposes of this representation, a party is
related to IES if such party and IES would be treated as related parties within
the meaning of Treasury Regulations Section 1.368-1(e)(3).

         (c) Acquisition will acquire substantially all of the properties
including the business assets of the Company. For purposes of this
representation, amounts paid by the Company to dissenters, amounts paid by the
Company to Company Stockholder who receives cash or other property, amounts used
by the Company to pay reorganization expenses, and all redemptions and
distributions (except for regular, normal dividends, if any) made by the Company
immediately preceding the Merger, will be included as assets of the Company held
immediately prior to the Merger.


         (d) The Company and the Company Stockholder will pay their respective
expenses, if any, incurred in connection with the Merger.

         (e) There is no intercorporate indebtedness existing between IES and
the Company or between Acquisition and the Company that was issued, acquired or
will be settled at a discount.

         (f) The Company is not an investment company. For purposes of this
representation, an investment company means a regulated investment company (as
defined in the Code), a real estate investment trust (as defined in the Code),
or a corporation, 50 percent or more of the value of whose total assets are
stock and securities and 80 percent or more of the value of whose total assets
are assets held for investment within the meaning of Section 368(a)(2)(F)(iii)
of the Code.

         (g) The Company is not under the jurisdiction of a court in a case
under Title 11 of the United States Code, or a receivership, foreclosure, or
similar proceeding in a federal or state court.


                                     - 15 -
<PAGE>   21


         (h) On the date of the Merger, the fair market value of the assets of
the Company will exceed the sum of its liabilities, plus the amount of
liabilities, if any, to which its assets are subject.

         (i) None of the compensation received by any stockholder-employees of
the Company will be separate consideration for, or allocable to, any of their
shares of Company Common Stock. None of the shares of IES Common Stock to be
received by any stockholder-employee will be separate consideration for, or
allocable to, any employment agreements, and the compensation paid to any
stockholder-employee will be for services actually rendered and will be
commensurate with amounts paid to third parties bargaining at arm's length for
similar services.

         (j) The payment of cash in lieu of issuing fractional shares of IES
Common Stock is solely for the purpose of avoiding the expense and inconvenience
to IES of issuing fractional shares and does not represent separately
bargained-for consideration. The total cash consideration that will be paid in
the Merger to the Company Stockholder instead of issuing fractional shares of
IES Common Stock will not exceed one percent of the total consideration that

         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' 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 10.15).

         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

(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 the Merger
Consideration have been duly authorized and, when issued and delivered in
accordance with the terms of this Agreement, will

transactions contemplated hereby, are within the corporate powers of IES and
Acquisition and have been duly authorized by all necessary corporate action.
This Agreement has been duly 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 Authority, except (i) the filing of the
Certificates of Merger in accordance with Delaware Law and Georgia 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, or (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; (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.

         SECTION 4.5. SEC FILINGS. (a) IES has filed with the Securities and
Exchange Commission ("SEC") all material forms, statements, reports and

and the rules and regulations thereunder.

                  (b) As of its filing date, each IES SEC Filing complied as to
         form in 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 state any material fact necessary in order to make the
         statements made therein, in the light of the circumstances under which
         they were made, not misleading.

         "Prospectus"), as well as a copy of the annual report to shareholders
         for the year ended September 30, 1998 (the "Annual Report"). 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.

         SECTION 4.6. TAX TREATMENT. Neither IES nor, to IES' Knowledge, any of
its affiliates has taken, has agreed or failed to take, or intends to take any
action or has any knowledge of any fact or circumstance that would prevent the
Merger from qualifying as a 368 Reorganization.

         SECTION 4.7. SECTION 368(a)(2)(D) REPRESENTATIONS. IES hereby
represents and warrants the following to be true and correct as of the Effective
Time:

         (a) The Merger was negotiated through arm's length bargaining.
Accordingly, the fair market value of the IES stock and other consideration
received by the Company Stockholder will be approximately equal to the fair
market value of the Company Common Stock surrendered in the exchange.

         (b) Prior to the Merger, IES will be in control of Acquisition within
the meaning of Section 368(c)(1) of the Code.

         (c) Following the Merger, Acquisition has no current plan or intent to
issue additional shares of its stock that would result in IES losing control of
Acquisition within the meaning of Section 368(c)(1) of the Code.

         (d) IES has no current plan or intention to reacquire any of its stock
issued in the Merger.

         (e) IES has no current plan or intention to liquidate Acquisition; to
merge Acquisition with and into another corporation; to sell or otherwise
dispose of any of the assets of the Company acquired in the Merger, except for
dispositions made in the ordinary course of business or transfers described in
section 368(a)(2)(C) of the Code.

         (f) Following the Merger, Acquisition will continue the historic
business of the Company or use a significant portion of the Company's business
assets in a business.

the Company or between Acquisition and the Company that was issued, acquired, or
will be settled at a discount.

         (h) Neither IES nor Acquisition is an investment company as defined in
section 368(a)(2)(f)(iii) and (iv) of the Code.

         (i) None of the compensation received by any stockholder-employees of
the Company will be separate consideration for, or allocable to, any of their
shares of Company Common Stock. None of the shares of IES Common Stock to be
received by any stockholder-employee will be separate consideration for, or
allocable to, any employment agreements, and the compensation paid to any
stockholder-employee will be for services actually rendered and will be
commensurate with amounts paid to third parties bargaining at arm's length for
similar services.

relating to Section 3.2 or Section 3.19 hereof or with respect to any Damages
that relate to or occur as a result of fraudulent misrepresentations or
fraudulent acts.

         Payment of Damages to IES Indemnitees can be made by paying 50% in IES
Common Stock and 50% in cash, the IES Common Stock being valued at the closing
of the day preceding the day of settlement.

         SECTION 6.2. INDEMNIFICATION RELATED TO TAX LIABILITIES. The Company
Stockholder 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
during all periods ending as of or prior to the Effective Time.

         SECTION 6.3. INDEMNIFICATION BY IES. IES covenants and agrees that it
will indemnify, defend, protect and hold harmless the Company Stockholder (the
"Stockholder Indemnitee") 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, costs, and expenses (including specifically, but without
limitation, fees, disbursements, and expenses of attorneys, accountants, other
professional advisors and of expert witnesses and costs of investigation and
preparation), as they are incurred, directly or indirectly resulting from,
relating to or arising out of:

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

         (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.

         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 60 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 Indemnitor'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, out-of-pocket expenses and allocable
share of employee compensation incurred in connection with such participation
for any employee whose participation is so requested. 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 legal fees and expenses) by the
Indemnitee in connection therewith as such amounts, liabilities, expenses and
fees are incurred.

         SECTION 6.5. OTHER REMEDIES. Notwithstanding the indemnification
obligations contained within this Article VI, in no event shall the
indemnification provisions hereof limit in any way the ability of any of the
parties to this Agreement to seek any other remedies which may be available to
them under law.

         SECTION 6.6. INDEMNIFICATION IF NEGLIGENCE OF INDEMNITEE. The
indemnification provided in this Article VI shall be applicable whether or not
negligence of the Indemnitee is alleged or proven.


                                     - 26 -
<PAGE>   32


         SECTION 6.7. NO THIRD-PARTY BENEFICIARIES. The foregoing
indemnification is given solely for the purpose of protecting the IES
Indemnitees and the Stockholder Indemnitee 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 Stockholder, 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 exceed, in the aggregate, one percent (1%) of
the value of the Merger Consideration, or $210,000; provided, however, that the
foregoing limitation on liability shall not apply with respect to indemnity
obligations under Section 6.1(a) relating to Section 3.2, Section 3.18, Section
3.19, or 6.1(e) hereof or with respect to any Damages that relate to or occur as
a result of fraudulent misrepresentations or fraudulent acts.

                                   ARTICLE VII

                            NONCOMPETITION COVENANTS

         SECTION 7.1. PROHIBITED ACTIVITIES. The Company Stockholder will not,
for a period of two (2) years following the Effective Time, directly or
indirectly, for himself or on behalf of or in conjunction with any or 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 any services or products 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) 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 services or
products in direct competition with IES or any of its subsidiaries within the
Territory;

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


                                     - 27 -
<PAGE>   33


         (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.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit the Company Stockholder from acquiring, as a passive investor with
no involvement in the operations of the business, not more than one percent (1%)
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, the 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 Stockholder 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 Stockholder 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.
During the term of this covenant, if IES or one of its subsidiaries engages in
new and different activities, enters a new business, or establishes new
locations for its current activities or business in addition to or other than
the activities or business it is currently conducting in the locations currently
established therefor, then the Company Stockholder will be precluded from
soliciting the customers or employees of such new activities or business or from
such new location and from directly competing with such new activities or
business within 100 miles of its then-established operating location(s) through
the term of these covenants.

         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 COVENANTS. The Company
Stockholder acknowledges that his agreements with the covenants set forth in
this Article VII are material conditions to IES' 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


                                     - 28 -
<PAGE>   34


cause of action of the 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 two (2) year period during which the agreements and
covenants of the Company Stockholder made in this Article VII shall survive
shall be computed by excluding from such computation any time during which the
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 hereof by any party hereto.

         SECTION 7.6. MATERIALITY. The Company and the Company Stockholder
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 STOCKHOLDER'S REPRESENTATIONS AND WARRANTIES
CONCERNING SECURITIES. As of the date hereof (which is the same date as the
Effective Time), the Company Stockholder hereby makes the following
representations and warranties to and for the benefit of IES: (i) that the
Company Stockholder has been provided with copies of the Prospectus and annual
report and have been provided as much time and opportunity as he 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 Stockholder has 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 Stockholder. The
Company Stockholder is able to bear the economic risk of an investment in the
IES Common Stock and can afford to sustain a total loss of such investment. The
Company Stockholder has such knowledge and experience in financial and business
matters that it, she or he is capable of evaluating the merits and risks of the
proposed investment and therefore has the capacity to protect its, her or his
own interests in connection with the acquisition of the IES Common Stock
pursuant hereto.

         SECTION 8.1. 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 Stockholder or family members, or trust in which the Company Stockholder
is both the grantor and the beneficiary, the trustees of which so agree), the
Company Stockholder shall not sell, assign, exchange, transfer, appoint, or
otherwise dispose of any shares of IES Common Stock received by the Company
Stockholder pursuant to this Agreement. The restriction set forth in this
Section 8.2 shall expire with respect to 20% of the IES Common Stock on the
first anniversary, 40% of the IES Common Stock on the second anniversary and 40%
of the IES Common Stock on the third anniversary of the Effective Time. The
certificates evidencing the IES Common Stock delivered to the Company
Stockholder 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:


                                     - 29 -
<PAGE>   35


         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
         DATES SPECIFIED IN THE AGREEMENT. FOLLOWING SUCH DATES THE ISSUER
         AGREES TO REMOVE THE RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH
         THE TRANSFER AGENT) UPON THE WRITTEN REQUEST OF THE HOLDER OF THIS
         CERTIFICATE.

                                   ARTICLE IX

                    NONDISCLOSURE OF CONFIDENTIAL INFORMATION

         SECTION 9.1. GENERAL. The Company Stockholder recognizes and
acknowledges that he 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 Stockholder agrees that he will not disclose
such confidential information to any Person for any purpose or reason whatsoever
(except such information as the Company Stockholder may be required to disclose
to any Governmental Authority or to authorized representatives of IES). In the
event of a breach or threatened breach by the Company Stockholder of the
provisions of this Section, IES shall be entitled to an injunction restraining
the Company Stockholder 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.

         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 Stockholder agrees that the foregoing covenants may be
enforced against him 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 9.3. NON-PUBLIC INFORMATION. The Company Stockholder hereby
acknowledges that if he becomes aware of "material non-public information" (as
defined under applicable securities laws) regarding IES, that he 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. The Company Stockholder further agrees to communicate such
requirement to all personnel of the Company, the Surviving Corporation or
others, having knowledge of such "material non-public information" regarding
IES.

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

         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

                                     - 32 -

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.

         SECTION 10.12. SPECIFIC PERFORMANCE. The parties hereto agree that

not performed in accordance with the terms hereof and that the parties shall be

the same agreement, and shall become effective when one or more counterparts
have been signed by each of the parties and delivered to the other party. In

for more than one such counterpart. A telecopied facsimile of an executed

agreement of each party to the terms hereof. However, each party agrees to
promptly deliver to the other parties an original, duly executed counterpart of
this Agreement.

         SECTION 10.14. MUTUAL INDEMNIFICATION AGAINST CLAIMS OF BROKERS. Each
