                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Western Directional, Inc.:

     We have audited the accompanying balance sheet of WESTERN DIRECTIONAL, INC.
as of December 31, 1998, and the related statements of operations, stockholders'
equity, 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 WESTERN DIRECTIONAL, INC. as
of December 31, 1998, and the results of its operations and cash flows for the
year then ended, in conformity with generally accepted accounting principles.

                       NOTES TO THE FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

     WESTERN DIRECTIONAL, INC. (the Company) located in Elk Grove, California,
is engaged in heavy engineering construction which includes installation of
underground communications cable, and various types of sewer, water, and natural
gas pipelines. The Company performs its contract work substantially under
unit-price contracts with various contracts being modified by incentive and
penalty provisions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Supplemental Cash Flow Information

     The Company had noncash investing activities of approximately $513,000
related to the purchase of approximately $965,000 in property and equipment
during the year ended December 31, 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.
Depreciation expense was $221,259 for the year ended December 31, 1998.

     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
estimated 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.

  Revenue Recognition

     The Company generally recognizes revenue as services are performed. The
Company's contracts, however, generally provide that the customer compensate the
Company only upon full completion of all contract services. Revenues are
recognized using the percentage-of-completion method measured by the percentage
of costs incurred to date to the total estimated costs for each contract.
Contract costs include all direct material, direct labor, subcontract cost and
indirect costs related to contract performance, such as indirect labor,
supplies, tools, repairs, interest, and depreciation. 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 contract
costs and income. The resulting effects are recognized in the period in which
the revisions are determined.

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

  Income Taxes

     The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 109,
"Accounting for Income Taxes." 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 the enacted tax rates and laws that will be in effect when the
underlying assets or liabilities are recovered or settled.

     For income tax purposes, the Company reports income on the accrual method
of accounting.

     The Company has elected to be taxed under the provisions of subchapter S of
the Internal Revenue Code and the Revenue and Taxation Code of the State of
California. Under those provisions, the Company did not

                                       10

pay federal corporate income taxes on its taxable income for the year ended
December 31, 1998. However, the Company did pay a California franchise tax at a
reduced rate of 1.5% on the taxable income it earned within California.

     The stockholders are liable for individual federal and California taxes on
the Company's taxable income. In order for the stockholders to be able to pay
these taxes, the board of directors of the Company has resolved that the
stockholders may take minimum annual dividends up to the full tax liability on
the Company's taxable income. The expected federal and California tax liability
on the Company's taxable income for the year ended December 31, 1998 is
approximately $622,000.

  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 assets and liabilities at the date of financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates. Reference is
made to the "Revenue Recognition" section of this footnote for discussion of
certain estimates reflected in the Company's financial statements.

8. FINANCIAL INSTRUMENTS:

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

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, business property liability, workers' compensation, general
liability and an umbrella policy.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

10. MAJOR CUSTOMERS AND RISK CONCENTRATION:

     The Company had sales greater than 10 percent of total sales to two major
customers (comprising approximately 85% and 12% of total sales) during the year
ended December 31, 1998. Approximately 97% of trade receivables are due from one
of the major customers.

     The Company grants credit, generally without collateral, to its customers,
which include publicly traded companies and general contractors. Consequently,
the Company is subject to potential credit risk related to changes in business
and economic factors. However, management believes that its contract acceptance,
billing and collection policies are adequate to minimize the potential credit
risk.

11. SUBSEQUENT EVENTS:

  Acquisition of Company

     On March 3, 1999, the Company was acquired by Quanta Services, Inc. and
operates as a division of Manuel Bros., Inc. (a wholly-owned subsidiary of
Quanta Services, Inc.). In conjunction with this acquisition, third party notes
payable of $409,727 were paid in full.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1998

1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The following items comprise the significant accounting policies of the
Company. The financial statements and notes are representations of the Company's
management, who is responsible for their integrity and objectivity. The policies
reflect industry practices and conform to generally accepted accounting
principles.

  Business Activity

     The Company is engaged in the design, engineering, and construction
management of communication towers throughout the United States. The Company is
headquartered in Houston, Texas.

  Interim Financial Information

     The unaudited interim financial statements have been prepared pursuant to
the rules of the Securities and Exchange Commission ("SEC"). Certain information
and footnote disclosures, normally included in annual financial statements
prepared in accordance with generally accepted accounting principles, have been
condensed or omitted pursuant to those rules and regulations, although the
Company believes that the disclosures made are adequate to make the information
presented not misleading. In the opinion of management, all adjustments,
consisting only of normal recurring adjustments, necessary to fairly present the
financial position, results of operations and cash flows with respect to the
interim consolidated financial statements, have been included. The results of
operations for the interim periods are not necessarily indicative of the results
of the entire fiscal year.

  Use of Estimates

     Management uses estimates and assumptions in preparing financial
statements. 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.

  Property and Equipment

     Property and equipment are carried at cost. Provisions for depreciation are
calculated using the straight-line method. Maintenance and repairs are charged
to operations when incurred. Betterment and renewals are capitalized. When
property and equipment are sold otherwise or disposed of, the asset account and
related accumulated depreciation accounts are reduced, and any gain or loss is
included in operations. Depreciation expense for the year ended December 31,
1998 was $91,772.

  Operating Cycle

     The Company's "operating cycle" is the length of each individual contract.
Therefore, the accounts and retainage receivable and payable related to
contracts and the future taxes related to income earned on the contracts in
progress are treated as current items.

  Comparative Statements

     The Company experiences significant changes in timing, size and type of
jobs from year to year. Because of the effect of such differences on the balance
sheet and the statement of operations and changes in financial position,
comparative statements would not be completely valid without additional
explanations which would detract from the clarity of the financial report.
Therefore, comparative statements have not been included in this report.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenues and Cost

     The Company recognizes revenues from fixed-price and modified fixed-price
construction contracts on the percentage-of-completion method, measured by the
percentage of cost incurred to date to estimated total cost 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.

     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 charges 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 assets, "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.

  Income Taxes

     The shareholders of Gem Engineering Co., Inc. have elected to be taxed
under Subchapter S of the Internal Revenue Code. Subchapter S taxes the
shareholders of the corporation individually on their proportionate share of the
corporation's income.

     The Company recognizes revenue on lump sum contracts on the percentage of
completion method of accounting for financial statement purposes and federal
income tax purposes. The Company has elected to convert from the cash basis of
accounting to the percentage of completion method as of January 1, 1997. The
Company will recognize the accumulated difference in the accounting methods at
January 1, 1997 of $1,517,598 over the next six years.

  Cash and Cash Equivalents

     Amounts included in cash and cash equivalents include cash on hand,
unrestricted cash deposits with banks, investments in money market mutual funds,
and short term (three months or less) securities of governmental agencies.

2 -- ACCOUNTS RECEIVABLE

     An aging of the accounts receivable of the Company at December 31, 1998 is

     The accounts receivable are pledged as security for the line of credit
loan. In management's opinion, an allowance for doubtful accounts is not deemed
necessary.

     During the year ended December 31, 1998, management wrote off as bad debts
$122,783 relating to prior year sales. The Company is currently pursuing
collection of these amounts even though they have been written off due to their
current inactivity.

4 -- INCOME TAXES

     As discussed in Note 1, the Company's shareholders elected to be taxed as a
Subchapter S Corporation. Subchapter S taxes the shareholders individually on
their proportionate share of the corporation's net income. Due to various timing
differences, income is recognized in different periods for tax reporting
purposes than for financial statement purposes. The shareholders taxable income
for the year ended December 31, 1998 will be as follows:

5 -- REVOLVING LINE OF CREDIT

     The Company has a line of credit with Merrill Lynch Business Financial
Services, Inc. in the amount of $2,000,000, with an expiration date of July 31,
2000. The line is secured by a first lien on all of the business assets of the
Company, and a personal guarantee of the shareholders of the company. The line
bears interest at 2.65% above the "30-day Dealer Commercial Paper Rate" reported
in the Wall Street Journal. The Company can borrow up to 80% of its accounts
receivable less than 90 days old, and not due from an affiliated person or
entity, or $2,000,000, whichever is less. At December 31, 1998, the Company did
not have an outstanding loan balance on the line.

     The line requires the Company have a "tangible net worth" in excess of
$1,000,000 and that the shareholders of the Company maintain personal liquidity
of cash and unencumbered marketable securities in excess of $1,000,000. The
Company is also required to maintain certain financial ratios during the term of
the loan.

6 -- RELATED PARTY TRANSACTIONS

     The shareholders of the Company (Gem) also own two other companies,
Communications Construction Incorporated (CCI) and Tower Erection Construction
Co., Inc. (TEC).

     Until 1997, CCI subcontracted tower communication work from Gem. CCI is not
presently performing any construction work and has loaned Gem $894,991 on an
unsecured basis with interest payable at 8.5%. Total interest paid CCI for 1998
was $66,483. In addition, $66,483 was owed to CCI as a result of intercompany

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

11 -- CONTINGENCIES

     The Company generally warrants its work to the owners of its completed work
for a period of one year. No allowance for warranty expense is provided, as
historically, this expense has been immaterial and charged to expense as
incurred.

     Contract payments on several jobs for the government have been reduced for
possible assessment of liquidating damages. In the opinion of management, the
government has no basis for the assessment when in fact the Company's claims for
additional reimbursement far exceed the liquidating damages which does not
include claims in revenues until the Company realization is probable and the
amount can be reliably estimated. The attorney representing the Company on these
claims has been engaged on a contingency fee arrangement so the Company should
not incur any legal cost in the pursuit of these claims.

     During the year the Company settled its lawsuit with Sherwin-Williams that
was filed on March 17, 1997. The suit alleged that Gem's subcontractor failed to
pay for paint delivered at the Jim Creek Naval Project. The suit was filed as a
Miller Act claim against Gem's bonding company. Gem was not a party, but
contractually agreed to indemnify the bonding company. The Company was
unsuccessful on its defense and incurred legal and settlement costs of $271,214,
which are included in indirect and administrative expenses for the year ended
December 31, 1998.

     Gem also incurred $103,170 in costs during the year to correct work
performed by one of its subcontractors, involving a communication tower for the
Kansas Department of Transportation. The tower suffered structural damage as a
result of improper installation, and the Company corrected the problem and
elected to avoid litigation with the subcontractor or its insurance company.

12 -- SUBSEQUENT EVENT TO AUDITOR'S REPORT (UNAUDITED)

     On May 28, 1999, the Company was acquired by Quanta Services, Inc. The
Company intends to lease certain property from the Company's shareholder
subsequent to the sale.

                           W.C. COMMUNICATIONS, INC.

                         NOTES TO FINANCIAL STATEMENTS
                                 (IN THOUSANDS)

1. BUSINESS AND ORGANIZATION

     W.C. Communications, Inc. (W.C. or the Company), a California Subchapter S
Corporation, is primarily engaged in the installation of fiber optic lines and
cables for the broadband industry in the continental United States. The Company
performs a majority of its contract work under unit-price contracts, with
contract terms generally ranging from three to 12 months.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Interim Financial Information

     The unaudited interim financial statements have been prepared pursuant to
the rules of the Securities and Exchange Commission (SEC). Certain information
and footnote disclosures, normally included in annual financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted pursuant to those rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements have been included. The results of
operations for the interim periods are not necessarily indicative of the results
of the entire year.

  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
deemed probable. As of December 31, 1998, management estimates all accounts to
be collectible.

  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 $279 for the year ended December 31, 1998.

     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 statement of operations.

  Revenue Recognition

     The Company recognizes revenue when services are performed under
unit-priced contracts. Such contracts generally provide that the customer accept
completion of progress to date and compensate the Company for services which
have been rendered, measured typically in terms of units installed, hours
expended or some other measure of progress. 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. 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 customer contracts will be due upon completion of the contracts
and acceptance by the customer. Based on the Company's experience

                                       31

                           W.C. COMMUNICATIONS, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

with similar contracts in recent years, the retention balance at each balance
sheet date will be collected within the subsequent fiscal year.

  Fair Value of Financial Instruments

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

  Warranty Costs

     For certain contracts, the Company warrants labor for the first year after
completion of the contract. An accrual for warranty costs is recorded based upon
the historical level of warranty claims and management's estimate of future
costs.

  Income Taxes

     The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company is not subject to taxation for federal
purposes. Under S Corporation status, the stockholders report their shares of
the Company's taxable earnings or losses in their personal tax returns. The
Company terminated its S Corporation status concurrently with the effective date
of its acquisition by Quanta Services, Inc. (see Note 8).

  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.

</TABLE>

     Rent expense for the year ended December 31, 1998, was $309. Assets under
capital leases are included as part of property and equipment.

5. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

     During 1998, the Company had sales greater than 10 percent of total sales
to three customers, which accounted for 42 percent, 23 percent and 18 percent,
respectively, of the Company's revenues. Approximately 38 percent, 26 percent
and 2 percent of trade and retainage receivables at December 31, 1998, are due
from each of these customers, respectively.

     The Company grants credit, generally without collateral, to its customers,
which include real estate operators, general contractors and state and
regulatory agencies located throughout the continental United States.
Consequently, the Company is subject to potential credit risk related to changes
in business and economic factors within these areas. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.

6. RELATED-PARTY TRANSACTIONS

     During 1998, a receivable to the sole stockholder was recorded. The
receivable balance at December 31, 1998, was $246 and was paid off in June 1999.

7. 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.

8. SUBSEQUENT EVENT

     In June 1999, the Company was acquired by Quanta Services, Inc.

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 combined financial position of North Sky
Communications and affiliates as of December 31, 1998 and the results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998

1. BUSINESS AND ORGANIZATION

     North Sky Communications (North Sky) was established in 1990 as a joint
venture between North Pacific Utility Contractors, Inc. (North Pacific) and Sky
Antenna Systems, Inc. (Sky Antenna), to enter into contracts for the
construction, repair, maintenance and extension of cable, both aerial and
underground. North Sky, North Pacific and Sky Antenna are collectively referred
to as North Sky Communications and affiliates (the Company). The Company
operates in one segment primarily in Oregon, Washington, California and Nevada.
A majority of the Company's contract work is under unit-price contracts.

     The allocation of joint venture income or loss and distribution of cash
flow is shared equally between North Pacific and Sky Antenna in accordance with
the Joint Venture Agreement.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Basis of Presentation

     The combined financial statements include the accounts of North Sky, North
Pacific and Sky Antenna, which are under common ownership. Because of the common
ownership and significant transactions between North Sky and the two
corporations, combined financial statements are presented. All significant
intercompany accounts and transactions have been eliminated.

  Interim Financial Information

     The unaudited interim financial statements have been prepared pursuant to
the rules of the Securities and Exchange Commission (SEC). Certain information
and footnote disclosures, normally included in annual financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted pursuant to those rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. In the opinion of management, all adjustment necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements have been included. The results of
operations for the interim periods are not necessarily indicative of the results
of the entire year.

  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
deemed probable. As of December 31, 1998, there was no allowance for doubtful
accounts.

  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
lease term or the estimated useful life of the asset. Depreciation and
amortization expense was $512,746 for the year ended December 31, 1998.

     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 statement of income.

  Revenue Recognition

     Generally, the terms of the Company's contracts are on a unit price basis,
whereby payment is made based upon the units of work performed. The Company
recognizes revenue on these contracts when services are performed. Occasionally,
the Company will perform work under a fixed price or cost plus fee contracts.
Revenues from such contracts are recognized under the percentage-of-completion
method, measured by the percentage of costs incurred to date to total estimated
costs for each contract. Contract costs include all direct material, labor and
subcontract 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 certain contracts will be due upon completion of the contracts and
acceptance by the customer. Based on the Company's experience with similar
contracts, the retention balance at the balance sheet date will be collected
within the subsequent fiscal year.

  Fair Value of Financial Instruments

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

  Income Taxes

     North Sky is a joint venture and is taxed as a partnership under the
Internal Revenue Code. North Pacific and Sky Antenna have elected to file U.S.
federal and state taxes pursuant to Subchapter "S" of the Internal Revenue Code.
Thus, U.S. federal and state income taxes become the responsibility of the
shareholders.

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

3. PROPERTY AND EQUIPMENT

     Property and equipment at December 31, 1998, consists of the following:

5. NOTES PAYABLE, RELATED PARTY

     Sky Antenna has a note payable to its sole shareholder of $641,685. North
Pacific has a note payable to its sole shareholder of $572,500. These notes bear
no interest, are due on demand and have been classified as current on the
accompanying combined balance sheet as of December 31, 1998. These notes
represent salaries due to the shareholders and were issued on December 31, 1998
(see Note 9).

6. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

     The Company's operations vary with the general economic conditions of the
telecommunication and cable industry. Financial instruments which potentially
expose the Company to concentration of credit risk consist primarily of trade
accounts receivable. During 1998, the Company had one customer who accounted for
57% of the Company's revenues. This same customer represented $1,773,686 or 59%
of the Company's accounts receivable as of December 31, 1998.

     Sky Antenna and North Pacific individually expensed $1,800,000 for salaries
to the shareholders for the year ended December 31, 1998.

9. SUBSEQUENT EVENT (UNAUDITED)

     Effective July 1, 1999, the Company was acquired by Quanta Services, Inc.
(Quanta). The related party notes payable were paid off by Quanta. After the
acquisition, North Sky, North Pacific and Sky Antenna were dissolved and a new
company was formed under Quanta. There were no material contingencies remaining

                         NOTES TO FINANCIAL STATEMENTS

A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Nature of Operations

     Crown Fiber Communications, Inc. ("the Company") incorporated in 1992 under
the laws of the State of Virginia. The Company is engaged in the construction
and installation of fiber optic and coaxial cable television and telephone
systems. The Company does not install headend electronics and equipment. Its
principal markets include Georgia, Virginia, Maryland, Alabama and Florida.

  Revenue Recognition

     The Company recognizes revenue from contracts on the completed-contract
method. This method is used because contracts are billed weekly on a per foot
basis and are cancelable at will. The results of this method on financial
position and results of operations do not vary significantly from those which
would result from use of the percentage-of-completion method.

  Interim Financial Information

     The unaudited interim financial statements have been prepared pursuant to
the rules of the Securities and Exchange Commission ("SEC"). Certain information
and footnote disclosures, normally included in annual financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted pursuant to those rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. In the opinion of management, all adjustments, necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements, have been included. The results of
operations for the interim periods are not necessarily indicative of the results
for the entire year.

  Accounts Receivable

     Management considers all accounts receivable to be collectible therefore no
allowance for doubtful accounts has been provided.

  Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Company considers all
instruments with an original maturity of three months or less to be cash
equivalents.

  Property and Equipment

     Property and equipment are stated at cost. Depreciation is provided by the
use of the straight-line and declining balance methods over the estimated useful
lives of the assets. Maintenance and repairs are charged to expense as incurred;
major renewals and betterments are capitalized. When items of property or
equipment are sold or retired, the related cost and accumulated depreciation are
removed from the accounts and any gain or loss is included in the results of
operations.

  Income Taxes

     The Company has elected to be taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions the shareholder is liable for
individual federal and state income taxes on the company's taxable income.
Therefore no provision or liability for federal or state income taxes has been
included in the financial statements.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Fair Value of Financial Instruments

     The Company's financial instruments include cash and cash equivalents,
accounts receivable, accounts payable and notes payable. The carrying amount of
these financial instruments have been estimated by management to approximate
fair value.

  Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. Those estimates and assumptions affect the reported amounts of
assets, liabilities, the disclosure of contingent assets and liabilities, and
the reported revenues and expenses.

  Deposits in Excess of Federally Insured Limits

     The Company maintains cash balances at several financial institutions. If
the financial institutions were not to honor their contractual obligations to
the Company, then the Company could incur losses. Management is of the opinion
that there is no risk because of the financial strength of the financial
institutions. Accounts at each institution are insured by the Federal Deposit
Insurance Corporation up to $100,000. At December 31, 1998, the Company's
uninsured cash bank balances total $2,220,427.

  Major Customers and Concentration of Credit Risk

     During 1998, the Company had greater than 10 percent of total sales to two
customers, which accounted for 40 and 32 percent of the company's revenues.
Approximately 14 percent of trade receivables at December 31, 1998, is due from
these customers. These customers have historically accounted for a significant
portion of the Company's business. Management anticipates the Company's
relationship with these customers to continue.

     The Company grants credit, generally without collateral, to its customers,
which include telecommunication utilities located throughout the southeastern
United States. Consequently, the company is subject to potential credit risk
related to changes in business and economic factors in the United States
telecommunications industry. However, management believes that its contract
acceptance, billing and collection policies are adequate to minimize the
potential credit risk.

We have audited the accompanying balance sheet of Edwards Pipeline Company LLC,
a North Carolina limited liability company, as of December 31, 1998, and the
related statements of operations, members' equity 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 Edwards Pipeline Company LLC as
of December 31, 1998, and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                           (IN THOUSANDS OF DOLLARS)

1. BUSINESS AND ORGANIZATION

     Edwards Pipeline Company LLC (Edwards or the Company) is a construction
contractor primarily engaged in pipeline installation for its customers that are
located primarily in North Carolina and South Carolina. Edwards performs a
majority of its contract work under unit-price and fixed-price contracts, with
contract terms generally ranging from six to 18 months.

     Edwards is a North Carolina limited liability company that is owned 65
percent by Edwards Utility Co., Inc., and 35 percent by WCE, Inc., and all
profits and losses are allocated ratably among the members.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Interim Financial Information

     The unaudited interim financial statements have been prepared pursuant to
the rules of the Securities and Exchange Commission (SEC). Certain information
and footnote disclosures, normally included in annual financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted pursuant to those rules and regulations, although the Company believes
that the disclosures made are adequate to make the information presented not
misleading. In the opinion of management, all adjustments necessary to fairly
present the financial position, results of operations and cash flows with
respect to the interim financial statements have been included. The results of
operations for the interim periods are not necessarily indicative of the results
for the entire year.

  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
deemed probable. As of December 31, 1998, management estimates all accounts to
be collectible.

  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 $641 for the year ended December 31, 1998.

     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 statement of operations.

  Other Assets, Net

     Goodwill, resulting from the acquisition of the Company in March 1995,
represents the excess of the acquisition cost over the fair value of the net
assets acquired and is being amortized on a straight-line basis over 40 years.
The net balance at December 31, 1998, was $364, and amortization expense for the
year ended December 31, 1998, was $10.

     In addition, the Company entered into a noncompete agreement with an
individual for $50, which is being amortized over the life of the agreement,
five years. The net balance at December 31, 1998, was $12, and amortization
expense for the year ended December 31, 1998, was $10.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Revenue Recognition

     The Company recognizes revenue when services are performed for unit-price
contracts. Unit-price contracts generally provide that the customer accept
completion of progress to date and compensate the Company for services which
have been rendered, measured typically in terms of units installed or some other
measure of progress. Revenues from fixed-price contracts are recognized on the
percentage-of-completion method, measured by the percentage of costs incurred to
date to total estimated costs for each contract. Contract costs include all
direct material, labor and subcontract 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 customer
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.

  Fair Value of Financial Instruments

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

  Income Taxes

     The Company is filing its tax returns as a partnership for federal income
tax purposes. Consequently, federal income taxes are not payable by, or provided
for, the Company. Members are taxed individually on their shares of the
Company's earnings. The Company's net income or loss is allocated among the
members in accordance with an agreement between the members.

  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.

5. RETIREMENT PLAN

     The Company has a deferred contribution profit sharing plan which covers
substantially all employees who have completed six months of service. The
Company follows the policy of funding retirement plan contributions annually as
accrued. The Company's contributions are determined at the discretion of the
members. The Company contributed $20 for 1998.

6. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK

     During 1998, the Company had greater than 10 percent of total sales to
three customers, which accounted for 44 percent, 23 percent and 18 percent,
respectively, of the Company's revenues. Approximately 0 percent, 24 percent and
66 percent of trade and retainage receivables at December 31, 1998, are due from
each of these customers, respectively.

     The Company grants credit, generally without collateral, to its customers,
which include real estate operators, general contractors and state and
regulatory agencies located throughout the continental United States.
Consequently, the Company is subject to potential credit risk related to changes
in business and economic factors within these areas. However, management
believes that its contract acceptance, billing and collection policies are
adequate to minimize the potential credit risk.

                          INDEPENDENT AUDITOR'S REPORT

To Haines Construction Co.:

     I have audited the accompanying balance sheet of Haines Construction Co.
(an Oklahoma Corporation) as of March 31, 1999 and the related statements of
income, stockholder's equity and cash flows for the year then ended. These
financial statements are the responsibility of the Company's management. My
responsibility is to express an opinion on these financial statements based on
my audit.

     I conducted my audit in accordance with generally accepted auditing
standards. Those standards require that I 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.
I believe that my audit provides a reasonable basis for my opinion.

     In my opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Haines Construction Co. as
of March 31, 1999, and the results of operations and its cash flows for the year
then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 1999

NOTE 1 -- BUSINESS AND SUMMARY OF ACCOUNTING POLICIES

     Haines Construction Co. (Haines or the Company) is a construction
contractor primarily engaged in pipeline installation for its customers that are
located primarily in Oklahoma, Texas and Kansas. Haines performs a majority of
its contract work under unit-price and fixed-price contracts, with contract
terms generally ranging from six to 12 months.

     A summary of the Company's significant accounting policies consistently
applied in the preparation of the accompanying financial statements follows.

  Interim Consolidated Financial Information

     The unaudited interim consolidated financial statements have been prepared
pursuant to the rules of the Securities and Exchange Commission ("SEC"). Certain
information and footnote disclosures, normally included in annual financial
statements prepared in accordance with generally accepted accounting principles,
have been condensed or omitted pursuant to those rules and regulations, although
the Company believes that the disclosures made are adequate to make the
information presented not misleading. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows with
respect to the interim consolidated financial statements, have been included.
The results of operations for the interim periods are not necessarily indicative
of the results for the entire fiscal year.

  Accounting Basis for Recording Income

     Profits on contracts are recorded on the percentage of completion method,
whereby recognition of earnings on contracts in progress is calculated based on
the ratio of cost incurred to date to expected cost to be incurred on each
contract. Contract costs include all direct material supplies, labor,
subcontracts, equipment costs, travel and per diem, and insurance and bonding
expense. 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. Any
required adjustments are recognized in the period in which the revisions become
known. At the time a loss on a contract becomes known, the entire amount of the
estimated ultimate loss on the contract is accrued.

     Non-contract revenue and expenses are reported on the accrual method of
accounting.

  Accounts Receivable

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

  Depreciation

     Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over their estimated service lives using the
straight-line method. Depreciation of $649,091 was reported for the current
year.

  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 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.

NOTE 5 -- LEASES

     The Company leases commercial property and equipment from HCC Rental
Services, LLC, a company owned by William B. Haines. The expense for the period
ending March 31, 1999 was $279,173. Future lease expenses cannot be determined
at this time.

     The Company also leased several vehicles under cancelable operating leases,
which expired October 31, 1998. The payments were $6,384 per month. Rental
expense that related to these operating leases was $44,687.

NOTE 6 -- INCOME TAXES

     Effective April 1, 1993, Haines Construction Co. adopted SFAS No. 109,
Accounting for Income Taxes, which requires an asset and liability approach to
financial accounting and reporting for income taxes. The difference between the
financial statement and tax basis of assets and liabilities is determined
annually.

     Deferred income tax assets and liabilities are computed for those
differences that have future tax consequences using the currently enacted tax
laws and rates that apply to the periods in which they are expected to affect
taxable income. Valuation allowances are established, if necessary, to reduce
the deferred tax liability to the amount that will more likely than not be
realized. Income tax expense is the current tax payable or refundable for the
period plus or minus the net change in the deferred tax assets and liabilities.

     Since the Company uses the ACRS/MACRS methods of accounting for income tax
purposes, the primary temporary differences between tax and financial statements
are depreciation and deferred revenue related to a change in tax accounting
method.

     SFAS 109 requires the following disclosure of the Company's total deferred
tax assets and liabilities:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     After considering all of the evidence, both positive and negative,
management has concluded it is more likely than not that all-future tax benefits
will be realized. Therefore, a valuation allowance is not needed for the
deferred tax liability. There was no prior balance in the valuation allowance
and therefore there was no change in the valuation allowance this period.

NOTE 7 -- CONCENTRATION OF CREDIT RISK

     The Company contracts to construct oil and natural gas pipelines primarily
in Oklahoma, Texas, and Kansas. Credit is extended based on an evaluation of
each customer's financial condition. Credit losses, if any, have been provided
for in the financial statements and have been generally within management's
expectations.

     The Company has concentrated its credit risk for cash by maintaining
deposits in financial institutions located within the same Oklahoma region,
which at times may exceed insured limits. The maximum loss that would have
resulted from that risk totaled $2,149,470 at March 31, 1999 for the excess of
the deposit liabilities reported by the financial institutions over the amounts
that would have been covered by federal insurance.

NOTE 8 -- EMPLOYEE BENEFIT PLAN

     The Company maintains a profit sharing plan covering substantially all
full-time employees. The Board of Directors determines contributions to the
plan. For the year ending March 31, 1999, the total profit sharing plan expense
was $54,235.

NOTE 9 -- CONTINGENT LIABILITIES

     The Company has one pending lawsuit in which it is named as the defendant.
Management is of the opinion that the final settlement will be favorable to the
Company. Therefore, no provision has been made in the financial statements for
the outcome of the lawsuit.

NOTE 10 -- NOTES RECEIVABLE

     Companies owned by William B. Haines owed the Company $580,029 in the form
of notes receivable and $3,096 accrued interest receivable.

NOTE 11 -- SUBSEQUENT EVENTS

     Subsequent to the balance sheet date, the Company incurred a note payable
in the amount of $413,806 for the purchase of equipment. In September 1999, the
Company was acquired by Quanta Services, Inc. and certain installment notes
payable were repaid. (Unaudited).

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

  Nature of business

     Bonneville Construction Company, Inc. (the "Company") was organized under
the laws of the State of Idaho on January 1, 1973. The Company leases its
corporate headquarters located in Las Vegas, Nevada, on a month to month basis.
The Company operates in the Western United States and the Pacific Island
regions. The Company is principally engaged in the construction of communication
cable systems. In connection with its normal construction activities, the
Company may be required to acquire performance bonds. The surety issuing the
bonds has recourse against the Company's assets in the event the surety is
required to honor the bonds. The length of the Company's contracts varies but is
typically less than one year. Billings are submitted as work progresses and the
balance and retainages are due upon completion.

  (Unaudited) Interim financial statements

     The accompanying balance sheet as of September 30, 1999 and the statements
of operations, stockholder's equity and cash flows for the nine months ended
September 30, 1999 and 1998, have not been audited. However, those financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information. Accordingly, they do not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In management's opinion, the
accompanying interim financial statements reflect all material adjustments
(consisting only of normal recurring accruals) necessary for a fair presentation
of the financial results for the interim periods presented. The financial
results for the nine months ended September 30, 1999 and 1998 are not
necessarily indicative of the financial results which will be reported for the
entire year.

     A summary of the Company's significant accounting policies follows:

  Use of estimates in the preparation of financial statements

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount 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. The Company's method of revenue recognition from construction
contracts is based significantly on estimates. Actual results could differ from
those estimates.

  Cash and cash equivalents

     For purposes of reporting cash flows, the Company considers investments
held in a bank sweep account to be cash equivalents.

     At various times throughout the year, the Company maintained cash balances
at financial institutions in excess of federally insured limits.

  Materials and supplies inventory

     Materials and supplies inventory are valued at the lower of cost (first-in,
first-out method) or market.

  Furniture and equipment

     Furniture and equipment are stated at cost, less accumulated depreciation.
Depreciation is provided primarily on the straight-line method over the
estimated lives of the related assets which range from 3 to 10 years.

<PAGE>   78
                     BONNEVILLE CONSTRUCTION COMPANY, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Income taxes

     The Company has elected, with the consent of its stockholders, to be taxed
under the provisions of Subchapter "S" of the Internal Revenue Code. Under those
provisions, the Company does not pay federal corporation income taxes on its
taxable income. Instead the stockholders account for their pro rata share of the
Company's income, losses, deductions and credits. As a result of this election,
no provision for income tax for the Company has been made in the accompanying
financial statements. The Company's tax basis in its assets and liabilities do
not differ materially from the basis for financial reporting.

  Revenue and cost recognition

     Revenues from fixed-price and unit-based 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. These
contracts generally provide that the customer accept completion of progress to
date and compensate the Company for services rendered measured typically in
terms of units installed or some other measure of progress. This method is used
because management considers the cost-to-cost method to be the best available
measure of progress on these contracts. No gross profit is recognized until a
contract has reached a stage of completion sufficient to reasonably determine,
in the opinion of management, the ultimate realizable profit. Provisions for
estimated losses on uncompleted contracts are made in the period such losses
become apparent.

     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. Also included in contract costs
are prepaid materials that have been purchased and billed to the owner. No gross
profit is recognized on these costs until used on the contract. General and
administrative costs and unallocated equipment costs are charged to expense as
incurred. Changes in job performance, job conditions, 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 Company believes that the retentions receivable balance as shown will
be collected within the next fiscal year.

     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 revenue recognized.

  Fair value of financial instruments

     The carrying amounts of financial instruments including cash, accounts
receivable, advances to related parties and accounts payable approximate their
fair values because of their short maturities.

     The carrying amounts of the line of credit, long-term debt, and due to
related parties approximate their fair values because the interest rates on
these instruments are at market rates.

     Accounts receivable consist of the following at December 31, 1998:

NOTE 6 -- JOINT VENTURE

     In February 1998, the Company entered into a joint venture arrangement with
a subcontractor to manage certain construction contracts. As part of this
agreement, the Company purchased existing receivables of the subcontractor in
exchange for cash. The subcontractor subsequently collected on these
receivables, but failed to remit the funds to the Company. As a result, the
Company recognized a loss of approximately $182,000 which is included in bad
debt expense at December 31, 1998. The agreement was rescinded in May 1998, with
no further liability to the Company.

The Company borrowed $645,000 to be repaid in 60 monthly payments of $13,363,
including interest at 8.85%. The loan is secured by certain existing equipment

extended through November 1999, under similar terms.

CONTRACT NEGOTIATION

unrelated third party where the resolution of certain change orders are under
negotiation. The third party is withholding payment of remaining balances due on
the contract totaling approximately $2,000,000 pending agreement on the costs
and merits of the work performed. Management has reduced the amounts billed as
of September 30, 1999 to the amount it expects to collect on resolution of these

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Trawick Construction Company Group:

     We have audited the accompanying combined balance sheet of Trawick
Construction Company Group (the Group) as defined in Note 1 to the combined
financial statements as of December 31, 1998 and the related combined statements
of income, stockholders' equity, and cash flows for the year then ended. These
combined financial statements are the representation of the Group'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 from
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 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 combined financial position of Trawick
Construction Company Group as of December 31, 1998, and the results of their
combined operations and their combined cash flows for the year then ended in
conformity with generally accepted accounting principles.

                       TRAWICK CONSTRUCTION COMPANY GROUP

                   NOTES TO THE COMBINED FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS AND ORGANIZATION

     Trawick Construction Company Group (the Group) includes the financial
statements of the following companies under common control and ownership:
Trawick Construction Company, Inc. (a Florida S-corporation) and Communication
Manpower, Inc. (a Florida S-corporation.) Trawick Construction Company, Inc.
operates in the telephone line installation industry. Communication Manpower,
Inc. provides labor to telecommunication companies.

  Common Stock

     Common stock at December 31, 1998, is composed of the following:

          a. Trawick Construction Company, Inc. -- 500 shares authorized,
     issued, and outstanding at $100 par value per share

          b. Communication Manpower, Inc. -- 1,000 shares authorized, issued,
     and outstanding at $1 par value per share

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Combination

     The combined financial statements of the Group include the accounts of the
entities listed in Note 1. All significant intercompany accounts and
transactions have been eliminated in combination.

  Interim Combined Financial Information

     The interim combined financial statements for the nine months ended
September 30, 1998 and 1999, 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 footnote disclosures
required by generally accepted accounting principles for complete financial
statements. In the opinion of the Group's management, the unaudited interim
combined financial statements contain all adjustments, consisting of normal
recurring adjustments considered necessary for a fair presentation. The combined
results of operations for the combined interim periods are not necessarily
indicative of the results for the entire fiscal year.

  Revenue Recognition

     The Group recognizes revenue when services are performed, except when work
is being performed under a fixed-price contract. These fixed-price contracts
generally provide that the customer accept completion of progress to date and
compensate the Group for services which have been rendered, measured typically
in terms of units installed, hours expended, or some other nature of progress.
Revenues from fixed-price contracts are recognized on the
percentage-of-completion method, measured by the percentage of costs incurred to
date to total estimated costs for each contract. Contract costs include all
direct material, labor and subcontract 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 identified. Changes in
job performance, job conditions, estimated profitability, and final contract
settlements may result in revisions to estimated costs and revenues. The effects
of these revisions are recognized in the period in which the changes occur.

     The balances billed but not paid by customers pursuant to retainage
provisions in customer contracts will be due upon completion of the contracts
and acceptance by the customer. The Group believes that the retention balance
shown on the accompanying combined balance sheet will be collected within the
next fiscal year.

                       TRAWICK CONSTRUCTION COMPANY GROUP

           NOTES TO THE COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  Marketable Securities

     Marketable securities have been categorized as available for sale
securities and as a result are stated at fair value. Unrealized holding gains
and losses are included as a component of stockholders' equity until realized.

  Accounts Receivable

     The Group considers accounts receivable to be fully collectible;
accordingly, no allowance for doubtful accounts is required.

  Cash and Cash Equivalents

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

  Compensated Absences

     Employees of the Group are entitled to paid vacation, paid sick days, and
personal days off, depending on job classification, length of service, and other
factors. It is impractical to estimate the amount of compensation for future
absences and, accordingly, no liability has been recorded in the accompanying
financial statements. The Group's policy is to recognize the costs of
compensated absences when actually paid to employees.

  Customer Deposits

     Advance payments for future work received from customers is recorded as
customer deposits under current liabilities. The payments are recognized as
income as the work is performed, which is believed to be within one year.

  Use of Estimates

     The Group is required to make estimates and assumptions in preparing
financial statements in conformity with generally accepted accounting
principles. These 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 differ from those
estimates.

  Fair Value of Financial Instruments

     The Group's financial instruments consist of cash, accounts receivable,
accounts payable, and debt. The Group believes that the carrying value of these
instruments on the accompanying combined balance sheet approximates their fair
value due to either the short-term nature of the instrument or the interest
rates on the debt being comparable to rates currently available to the Group.

NOTE 3 -- PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost and depreciated over the
estimated useful lives of the various assets generally by accelerated methods.

     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 combined statements of operations.

</TABLE>

     The total depreciation expense was $715,955 for 1998.

NOTE 4 -- PROFIT SHARING PLAN

     The Group maintains a qualified profit sharing plan for substantially all
full-time employees. The annual contribution to the plan, as determined by the
Board of Directors, is discretionary but may not exceed 15% of the annual
aggregate compensation paid to all participating employees. The contribution was
$245,505 in 1998.

NOTE 5 -- INCOME TAXES

     Both Trawick Construction Company, Inc. and Communication Manpower, Inc.,
with the consent of their stockholders, have elected S-corporation status under
appropriate sections of the Internal Revenue Code and a similar section of the
Florida income tax laws, which provide that in lieu of corporate income taxes,
the stockholders have consented to include their proportionate share of each
company's taxable income in their individual returns. Therefore, these
statements do not include a provision for Federal or Florida income taxes.

     The income taxes shown on the statements of income represent income taxes
due to the States of Alabama, Georgia, and Mississippi.

NOTE 6 -- OPERATING LEASES

     The Group had an agreement with a party related to one of its stockholders
for the rental of land and building on an annual basis. The lease was treated as
an operating lease under generally accepted accounting principles. The total
rent expense was $32,000 for 1998.

     During 1998, the Group purchased the real estate at its fair market value.

     The Group has other operating lease arrangements for temporary rental of
equipment at its job site locations for lease terms of less than one year. The
minimal lease payment for the next lease term will be approximately $174,000.

of credit risk consist principally of temporary cash investments and trade

credit evaluations of its customers' financial condition and, generally,
requires no collateral from its customers.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Conti Enterprises, Inc.:

     We have audited the accompanying statement of assets, liabilities and
divisional equity of the Telecommunications Division of Conti Enterprises, Inc.
as of December 31, 1998, and the related statements of divisional operating
profit 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.

                            CONTI ENTERPRISES, INC.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS AND SUMMARY OF ACCOUNTING POLICIES:

  Business:

     The Telecommunications Division (the "Division") of Conti Enterprises, Inc.
(the "Company") is engaged primarily as a utility contractor for private
entities located in the eastern United States.

  Basis of presentation:

     The accompanying financial statements present the financial position and
results of operations and cash flows of the Division and are not intended to
present the financial position, results of operations and cash flows of the
Company taken as a whole. In addition, as discussed in Note 4, certain expenses
have been allocated to the Division by the Company and, accordingly, the
accompanying financial statements are not necessarily indicative of the
financial position, results of operations or cash flows of the Division had it
operated as a separate entity.

     The unaudited financial statements have been prepared pursuant to the rules
of the Securities and Exchange Commission ("SEC"). In the opinion of management,
all adjustments, consisting only of normal recurring adjustments, necessary to
fairly present the financial position, results of operations and cash flows with
respect to the unaudited financial statements of the Division, have been
included. The results of operations for the interim periods are not necessarily
indicative of the results for the entire 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 certain reported amounts and disclosures. Accordingly,
actual results could differ from those estimates.

  Basis for recording income on construction contracts:

     Profits on contracts are credited to income under the
percentage-of-completion method of accounting, based on the estimated stage of
completion of individual contracts. At the time a loss on a contract becomes
known, the entire amount of the estimated ultimate loss on both short and
long-term contracts is recorded. Because of the inherent uncertainties in
estimating costs, it is at least reasonably possible that the estimates used
will change within the near term.

  Machinery and equipment:

     Machinery and equipment are stated at cost, net of depreciation to date.
Depreciation is provided on the straight-line method at rates calculated to
provide for the retirement of machinery and equipment at the end of their
estimated useful lives.

  Income taxes:

     The Company, with the consent of its stockholders, has elected to be
treated as an "S" Corporation under Sections 1371-1378 of the Internal Revenue
Code. Under these sections, corporate income or loss, in general, is allocated
to the stockholders for inclusion in their personal income tax returns.
Accordingly, there is no provision for Federal income tax in the accompanying
financial statements attributable to the operations of the Division.

NOTE 4 -- ALLOCATED COSTS AND EXPENSES:

     Common corporate general and administrative expenses, interest expense,
other income and owner's compensation are allocated among each of the Company's
divisions based primarily on a percentage of direct construction costs.

     Management considers its methodologies for specifically identifying or
allocating costs and expenses to the Division to be reasonable and to present
fairly the costs and expenses of the Division.

NOTE 5 -- SUBSEQUENT EVENT:

     On October 1, 1999, the Company sold the Division to Quanta Services, Inc.
("Quanta") for cash and stock of Quanta.

ITEM 7. PRO FORMA FINANCIAL INFORMATION

                     QUANTA SERVICES, INC. AND SUBSIDIARIES

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

                             BASIS OF PRESENTATION

     The following unaudited pro forma combined financial statements include the
consolidated financial statements of Quanta Services, Inc. and subsidiaries
("Quanta" or the "Company") as of September 30, 1999 and for the nine months
then ended (unaudited) and for the year ended December 31, 1998 adjusted as
follows: (i) the unaudited pro forma combined balance sheet at September 30,
1999 gives effect to the acquisition of nine businesses acquired by Quanta from
October 1, 1999 through November 1, 1999 (the "Subsequent Acquisitions") as if
they occurred on September 30, 1999; (ii) the unaudited pro forma combined
statement of operations for the year ended December 31, 1998 gives effect to the
following events as if they had occurred on January 1, 1998 (a) Quanta's initial
public offering ("IPO"), (b) the pre-acquisition results of the four entities
acquired concurrent with the IPO ("the Founding Companies") and eleven
additional businesses acquired subsequent to the IPO through December 31, 1998
which were accounted for using the purchase method of accounting (together, the
"1998 Acquisitions"), (c) the acquisition of 39 businesses accounted for using
the purchase method of accounting from January 1, 1999 through November 1, 1999
(the "1999 Acquisitions"), (d) the issuance of the Convertible Subordinated
Notes, (e) the follow-on public offering completed by Quanta in January of 1999
and (f) the issuance of Series A Convertible Preferred Stock in September of
1999; and (iii) the unaudited pro forma combined statement of operations for the
nine months ended September 30, 1999 gives effect to the following events as if
they had occurred on January 1, 1999 (a) the follow-on public offering, (b) the
pre-acquisition results of the 1999 Acquisitions as if they occurred on January
1, 1999 and (c) the issuance of Series A Convertible Preferred Stock in
September of 1999.

     Quanta has preliminarily 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 companies have contractually agreed to prospective
reductions in salaries, bonuses, benefits and lease payments, these reductions
have been reflected in the unaudited pro forma combined statements of
operations. With respect to other potential cost savings, Quanta has not and
cannot quantify these savings until a period subsequent to the acquisitions. It
is anticipated that these savings will be partially offset by costs related to
Quanta's new corporate infrastructure and by the costs associated with being a
public company. However, because these costs cannot be accurately quantified at
this time, they have not been included in the pro forma financial information of
Quanta.

     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 Quanta's financial position or
results of operations would actually have been if such transactions in fact had
occurred on those dates and are not necessarily representative of Quanta's
financial position or results of operations for any future period. Since the
acquired businesses were not under common control or management during the
entire period covered by the pro forma financial statements, 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 Company's historical consolidated financial statements and notes
thereto included in the Company's Annual Report on Form 10-K which was filed
with the SEC on March 31, 1999 and additionally the Company's related financial
statements on Form 8-K which was filed with the SEC on June 17, 1999 giving
effect to a pooling-of-interests transaction which occurred in February 1999.
