RISK FACTORS

An investment in our common stock involves a high degree of risk. You
should carefully consider the risks described below and the other information
contained in this prospectus before deciding to invest in our common stock. We
believe the following risks represent the known, material risks facing our
company, in addition to the risks which typically face any company in our
industry. If any of the following risks actually occur, our business, financial
condition and operating results could be materially adversely affected. In that
case, the trading price of our common stock could decline, and you could lose a
part or all of your investment.

WE HAVE A LIMITED HISTORY OF OPERATING AND INTEGRATING OUR ACQUIRED BUSINESSES

If we are unable to integrate or successfully manage the companies we have
acquired or may acquire in the future, our business, financial condition and
results of operations could be materially and adversely affected. We were
founded in August 1997 but conducted no operations and generated no revenues
prior to acquiring four businesses in February 1998. These four businesses and
the other businesses we have acquired since February 1998 have been operating as
separate entities and we expect that many of these businesses and many others we
acquire will continue to operate as separate entities with a large degree of
operating autonomy. To manage the combined enterprise on a profitable basis, we
must institute certain necessary common systems and procedures. We intend to
integrate the computer, accounting and financial reporting systems, and certain
of the operational, administrative, banking and insurance procedures of the
businesses we acquire. However, we cannot be certain that we will successfully
institute these common systems and procedures. In addition, we cannot be
certain that our recently assembled management group will be able to
successfully manage the businesses we acquire as a combined entity and
effectively implement our operating or growth strategies.

THERE ARE RISKS RELATED TO OUR OPERATING AND INTERNAL GROWTH STRATEGIES

A key element of our strategy is to increase the profitability and revenues
of the businesses we acquire. Although we have begun to implement this strategy
by various means, we cannot be certain that we will be able to continue to do so
successfully. Another key component of our strategy is to operate the
businesses we acquire on a decentralized basis, with local management retaining
responsibility for day-to-day operations, profitability and the internal growth
of the individual business. If we do not implement proper overall business
controls, this decentralized operating strategy could result in inconsistent
operating and financial practices at the businesses we acquire, and our overall
profitability could be adversely affected. Our ability to generate internal
growth will be affected by, among other factors, our ability to:

. expand the range of services we offer to customers;

. attract new customers;

. increase the number of projects performed for existing customers;

. hire and retain employees;

5



. open additional facilities; and

. reduce operating and overhead expenses.

Many of the factors affecting our ability to generate internal growth may
be beyond our control, and we cannot be certain that our strategies will be
successful or that we will be able to generate cash flow sufficient to fund our
operations and to support internal growth. Our inability to achieve internal
growth could materially and adversely affect our business, financial condition
and results of operations.

WE MAY BE UNSUCCESSFUL IN IDENTIFYING OR INTEGRATING ACQUIRED COMPANIES

We have grown rapidly through the acquisition of 55 businesses. A
principal part of our business growth strategy will be to make additional
acquisitions on a selective basis as opportunities arise. One of our principal
growth strategies is to increase our revenues and the markets we serve through
the acquisition of additional electric and telecommunications infrastructure
contracting companies. We expect to face competition for acquisition
candidates, which may limit the number of acquisition opportunities and may lead
to higher acquisition prices. We cannot be sure that we will be able to
identify, acquire or profitably manage additional businesses. We also cannot be
sure that we can integrate successfully any acquired businesses with our other
operations without substantial costs, delays or other operational or financial
problems. Further, acquisitions involve a number of special risks which could
materially and adversely affect our business, financial condition and results of
operations. These special risks include:

. failure of the acquired businesses to achieve the results we expect;

. diversion of our management's attention from operational matters;

. our inability to retain key personnel of the acquired businesses;

. risks associated with unanticipated events or liabilities;

. difficulties integrating the operations and personnel of acquired companies;

. the potential disruption of our business;

. the difficulty of maintaining uniform standards, controls, procedures and
policies; and

. customer dissatisfaction or performance problems at the acquired business may
materially and adversely affect the reputation of our company.

WE MAY NOT HAVE ACCESS TO SUFFICIENT FUNDING TO FINANCE FUTURE ACQUISITIONS

If we cannot secure additional financing on acceptable terms, we may
be unable to pursue our acquisition strategy successfully and we may be unable
to support our growth strategy. We cannot readily predict the timing, size and
success of our acquisition efforts or the capital we will need for these
efforts. We intend to continue to use our common stock for all or a portion of
the consideration for future acquisitions. These issuances could have a
dilutive effect on our then existing

6


stockholders. If our common stock does not maintain a sufficient market value or
potential acquisition candidates are unwilling to accept our common stock as
part of the consideration for the sale of their businesses, we may be required
to utilize more of our cash resources to pursue our acquisition program. Using
cash for acquisitions limits our financial flexibility and makes us more likely
to seek additional capital through future debt or equity financings. If we seek
more debt, we may have to agree to financial covenants that limit our
operational and financial flexibility. If we seek more equity, we may dilute the
ownership interests of our then existing stockholders. When we seek additional
debt or equity financings, we cannot be certain that additional debt or equity
will be available to us at all or on terms acceptable to us. Our $350 million
revolving credit facility contains a requirement to obtain the consent of the
lenders for acquisitions exceeding a certain level of cash consideration.

OUR BUSINESS GROWTH COULD OUTPACE THE CAPABILITY OF OUR CORPORATE MANAGEMENT AND
SYSTEMS

We expect to grow both internally and through acquisitions. We expect
to expend significant time and effort in evaluating, completing and integrating
acquisitions and opening new facilities. We cannot be certain that our systems,
procedures and controls will be adequate to support our operations as they
expand. Any future growth also will impose significant additional
responsibilities on members of our senior management, including the need to
recruit and integrate new senior level managers and executives. We cannot be
certain that we can recruit and retain such additional managers and executives.
To the extent that we are unable to manage our growth effectively, or are unable
to attract and retain additional qualified management, our financial condition
and results of operations could be materially and adversely affected.

WE MAY BE UNABLE TO ATTRACT AND RETAIN QUALIFIED EMPLOYEES

Our ability to provide high-quality services on a timely basis
requires that we employ an adequate number of skilled electricians, journeymen
linemen and project managers. Accordingly, our ability to increase our
productivity and profitability will be limited by our ability to employ, train
and retain skilled personnel necessary to meet our requirements. We, like many
of our competitors, are currently experiencing shortages of qualified personnel.
We cannot be certain that we will be able to maintain an adequate skilled labor
force necessary to operate efficiently and to support our growth strategy or
that our labor expenses will not increase as a result of a shortage in the
supply of skilled personnel.

THE EXTENT OF OUR UNIONIZED WORKFORCE COULD ADVERSELY AFFECT OUR OPERATIONS OR
ACQUISITION STRATEGY

As of September 30, 1999, approximately 36% of our employees were
covered by collective bargaining agreements. Although the majority of these
agreements prohibit strikes and work stoppages, we cannot be certain that
strikes or work stoppages will not occur in the future. Strikes or work
stoppages would adversely impact our relationship with our customers and could
materially and adversely affect our business, financial condition and results of
operations. In addition, our acquisition strategy could be adversely affected
because of our union status for a variety of reasons. For instance, our union
agreements may be incompatible with the union agreements of a business we want
to acquire and some businesses may not want to become affiliated with a union
based company.

7



WE MAY BE UNABLE TO SUCCESSFULLY COMPETE WITH OTHER COMPANIES IN THE INDUSTRY

The electric and telecommunications infrastructure contracting
industry is highly competitive and is served by numerous small, owner-operated
private companies, public companies and several large regional companies. In
addition, relatively few barriers prevent entry into our industry As a result,
any organization that has adequate financial resources and access to technical
expertise may become one of our competitors. Competition in the industry
depends on a number of factors, including price. Certain of our competitors may
have lower overhead cost structures and may, therefore, be able to provide their
services at lower rates than we can provide such services. In addition, some of
our competitors are larger and have greater resources than us. We cannot be
certain that our competitors will not develop the expertise, experience and
resources to provide services that are superior in both price and quality to our
services. Similarly, we cannot be certain that we will be able to maintain or
enhance our competitive position.

We may also face competition from the in-house service organizations
of our existing or prospective customers. Electric utility and
telecommunications service providers usually employ personnel who perform some
of the same types of services as we do. We cannot be certain that our existing
or prospective customers will continue to outsource services in the future.

OUR DEPENDENCE UPON FIXED PRICE CONTRACTS AND MASTER SERVICE AGREEMENTS COULD
ADVERSELY AFFECT OUR BUSINESS

We currently generate, and expect to continue to generate, a
significant portion of our revenues under fixed price contracts. We must
estimate the costs of completing a particular project to bid for such fixed
price contracts. The cost of labor and materials, however, may vary from the
costs we originally estimated. These variations, along with other risks
inherent in performing fixed price contracts, may result in actual revenue and
gross profits for a project differing from those we originally estimated and
could result in reduced profitability and losses on projects. Depending upon
the size of a particular project, variations from estimated contract costs can
have a significant impact on our operating results for any fiscal quarter or
year.

Certain of our customers assign work to us on a project by project
basis under master service agreements. Under master service agreements, our
customer generally has no obligation to assign work to us. We cannot be certain
that customers with whom we have master service agreements will continue to
assign work to us. A significant decline in work assigned to us under these
contracts could materially and adversely affect our results of operations.

OUR OPERATING RESULTS MAY VARY SIGNIFICANTLY QUARTER-TO-QUARTER

The electric and telecommunications infrastructure contracting
business can be subject to seasonal variations. During the winter months,
demand for new projects and maintenance services may be lower due to inclement
weather. Additionally, the industry can be highly cyclical. As a result, our
volume of business may be adversely affected by declines in new projects in
various geographic regions of the U.S. Our quarterly results may also be
materially affected by:

. the timing of acquisitions;

. variations in the margins of projects performed during any particular
quarter;

8


. the timing and magnitude of acquisition assimilation costs;

. the timing and volume of work under new agreements;

. the budgetary spending patterns of customers;

. the termination of existing agreements;

. costs we incur to support growth internally or through acquisitions or
otherwise;

. the change in mix of our customers, contracts and business;

. increases in construction and design costs; and

. regional or general economic conditions.

Accordingly, our operating results in any particular quarter may not
be indicative of the results that you can expect for any other quarter or for
the entire year.

WE COULD HAVE POTENTIAL EXPOSURE TO ENVIRONMENTAL LIABILITIES

Our operations are subject to various environmental laws and regulations,
including those dealing with the handling and disposal of waste products, PCBs,
fuel storage and air quality. As a result of past and future operations at our
facilities, we may be required to incur environmental remediation costs and
other cleanup expenses. In addition, we cannot be certain that we will be able
to identify or be indemnified for all potential environmental liabilities
relating to any acquired business.

THE DEPARTURE OF KEY PERSONNEL COULD DISRUPT OUR BUSINESS

We depend on the continued efforts of our executive officers and on
senior management of the businesses we acquire. Although we intend to enter
into an employment agreement with each of our executive officers and other key
employees, we cannot be certain that any individual will continue in such
capacity for any particular period of time. The loss of key personnel, or the
inability to hire and retain qualified employees, could adversely effect our
business, financial condition and results of operations. We do not intend to
carry key-person life insurance on any of our employees.

SHARES ELIGIBLE FOR FUTURE SALE BY OUR CURRENT STOCKHOLDERS MAY ADVERSELY AFFECT
OUR STOCK PRICE


If our stockholders sell substantial amounts of our common stock
(including shares issued upon the exercise of outstanding options) in the public
market following this offering, the market price of our common stock could fall.
Such sales might make it more difficult for us to sell equity or equity-related
securities in the future at a time and price that we deem appropriate. As of
October 30, 1999 we have outstanding 36,461,949 shares of common stock and
Limited Vote Common Stock, assuming no exercise of outstanding options after
October 30, 1999 and no conversion of our convertible subordinated notes or
Series A Preferred Stock. Of these shares, the 2,034,849 shares offered by this
prospectus, together with 26,220,670 additional shares are freely tradable or
tradable pursuant to Rule 144.

9


CERTAIN PROVISIONS OF OUR ARTICLES OF INCORPORATION AND BYLAWS COULD MAKE AN
ACQUISITION OF OUR COMPANY MORE DIFFICULT

The following provisions of our certificate of incorporation and
bylaws, as currently in effect, as well as Delaware law, could discourage
potential acquisition proposals, delay or prevent a change in our control or
limit the price that investors may be willing to pay in the future for shares of
our common stock. Our certificate of incorporation permits our Board of
Directors to issue ''blank check'' preferred stock and to adopt amendments to
our bylaws. Our bylaws contain restrictions regarding the right of stockholders
to nominate directors and to submit proposals to be considered at stockholder
meetings. Also, our certificate of incorporation and bylaws restrict the right
of stockholders to call a special meeting of stockholders and to act by written
consent. We are also subject to provisions of Delaware law which prohibit us
from engaging in any of a broad range of business transactions with an
"interested stockholder" for a period of three years following the date such
stockholder became classified as an interested stockholder.

WE DO NOT EXPECT TO PAY DIVIDENDS IN THE NEAR FUTURE

We have never paid any cash dividends and do not anticipate paying
cash dividends on our common stock in the immediate future.

THE BOOK VALUE OF YOUR COMMON STOCK MAY BE SUBSTANTIALLY DILUTED

In the event that we issue additional common stock in the future, including
shares that may be issued in connection with future acquisitions or other public
or private financings, purchasers of common stock in this offering may
experience dilution.

THE YEAR 2000 PROBLEM COULD DISRUPT OUR BUSINESS

Many currently installed computer systems and software products are
coded to accept only two-digit entries in the date code field. Beginning in the
year 2000, these date code fields will need to accept four-digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
system and software used by many companies may need to be upgraded to comply
with such ''Year 2000'' requirements. We cannot be certain that unexpected Year
2000 compliance problems of our systems or of our vendors, customers and service
providers will not materially and adversely affect our business, financial
condition or operating results. The unanticipated failure of one of these
systems to properly recognize date information beyond the year 1999 could have a
significant adverse impact on our ability to deliver services to customers and
to manage our continuing operations.

OUR FORWARD-LOOKING STATEMENTS MAY PROVE TO BE INACCURATE

A number of statements in this prospectus address activities, events
or developments which we anticipate may occur in the future, including our
strategy for internal growth and improved profitability, the nature and amount
of additional capital expenditures, acquisitions of assets and businesses and
industry trends. These statements are based on certain assumptions and analyses
we make in light of our perception of historical trends, current business and
economic conditions and expected future developments, as well as other factors
we believe are reasonable or appropriate. However, whether actual results and
developments will conform with our expectations is subject to a number of risks
and uncertainties, including:

10


. the risk factors discussed in this prospectus;

. general economic, market or business conditions;

. the business opportunities (or lack thereof) that may be presented to and
pursued by us; and

. changes in laws or regulations and other factors.

Many of these risks and uncertainties are beyond our control.
Consequently, we cannot be certain that the actual results or developments that
we anticipate will be realized or, even if substantially realized, that they
will have the expected effects on our business or operations.

USE OF PROCEEDS

We will not receive any proceeds from the sale of shares by the
selling stockholder.

Mr. Jones has contractually agreed with us not to sell 1,017,425
shares of our common stock until August 13, 2000, and 508,712 shares of our
common stock until August 13, 2001.

PLAN OF DISTRIBUTION

The common stock may be sold or distributed from time to time by the
selling stockholder, or by pledgees, donees or transferees of, or other
successors in interest to, the selling stockholder, directly to one or more
purchasers, including pledgees, or through brokers, dealers or underwriters who
may act solely as agents or may acquire shares as principals, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices, or at fixed prices, which may be changed. The
distribution of the common stock may be effected by one or more of the following
methods:

. ordinary brokers' transactions, which may include long or short sales;

. transactions involving cross or block trades or otherwise on the New York
stock Exchange or other stock exchange on which the common stock may be
listed from time to time;

. purchases by brokers, dealers or underwriters as principals and resale by
such purchasers for their own accounts pursuant to this prospectus;

. "at the market" to or through market makers or into an existing market for
the common stock;

. in other ways not involving market makers or established trading markets,
including direct sales to purchasers or sales effected through agents;

. through transactions in options, swaps or other derivatives (whether
exchange-listed or otherwise); or

. any combination of the foregoing, or by any other legally available means.

12



In addition, the selling stockholder or his successors in interest may
enter into hedging transactions with broker-dealers who may engage in short
sales of common stock in the course of hedging the positions they assume with
the selling stockholder. The selling stockholder or his successors in interest
may also enter into option or other transactions with broker-dealers that
require the delivery to such broker-dealers of the shares, which shares may be
resold thereafter pursuant to this prospectus.

Brokers, dealers, underwriters or agents participating in the
distribution of the shares as agent may receive compensation in the form of
discounts, concessions or commissions from the selling stockholder (and, if they
act as agent for the purchaser of such shares, from such purchaser). Such
discounts concessions or commissions as to a particular broker, dealer,
underwriter or agent might be greater or less than those customary in the type
of transaction involved.

Any underwriter may engage in stabilizing transactions in accordance
with Rule 104 under the Exchange Act. Rule 104 permits stabilizing bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum. The underwriters may over-allot shares of the common stock
in connection with an offering of common stock, thereby creating a short
position in the underwriters' account. These transactions, if commenced, may be
discontinued at any time.

The selling stockholder and any brokers, dealers, underwriters or
agents that participate in the distribution of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act, and any discounts,
commissions or concessions received by any such persons might be deemed to be
underwriting discounts and commissions under the Securities Act. Neither we nor
the selling stockholder can presently estimate the amount of such compensation.
We know of no existing arrangements between the selling stockholder and may
other stockholder, broker, dealer, underwriter or agent relating to the sale or
distribution of the shares.

To the extent required, we will file, during any period in which
offers or sales are being made, a supplement to this prospectus which sets
forth, with respect to a particular offering, the specific number of shares to
be sold, the sales price, the name of any participating broker, dealer,
underwriter or agent, any applicable commission or discount and any other
material information with respect to the plan of distribution not previously
disclosed.

We will not receive any of the proceeds from the sale of the shares
offered by the selling stockholder. We will pay substantially all of the
expenses incident to this offering of the shares by the selling stockholder to
the public other than commissions and discounts of brokers, dealers,
underwriters or agents.

In order to comply with certain states' securities laws, if
applicable, the shares will be sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
common stock may not be sold unless the common stock has been registered or
qualified for sale in such state or an exemption from registration or
qualification is available and is satisfied.

LEGAL MATTERS

The validity of the shares of common stock offered hereby will be
passed upon for Quanta by Brad Eastman, Quanta's Vice President, Secretary and
General Counsel.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Delaware General Corporation Law

Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person in connection with such action, suit or proceeding if the
person acted in good faith and in a manner the person reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe the
person's conduct was unlawful. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had reasonable cause to
believe that the person's conduct was unlawful.

Section 145(b) of the DGCL states that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in

II-1


view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

Section 145(c) of the DGCL provides that to the extent that a present or
former director or officer of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he or she shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

Section 145(d) of the DGCL states that any indemnification under
subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made
by the corporation only as authorized in the specific case upon a determination
that indemnification of the present or former director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in subsections (a) and (b). Such determination shall be
made with respect to a person who is a director or officer at the time of such
determination (1) by a majority vote of the directors who are not parties to
such action, suit or proceeding, or (2) by a committee of such directors
designated by majority vote of such directors, even though less than a quorum,
or (3) if there are no such directors, or if such directors so direct, by
independent legal counsel in a written opinion, or (4) by the stockholders.

Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that he or she
is not entitled to be indemnified by the corporation as authorized in Section
145. Such expenses (including attorneys' fees) incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the corporation
deems appropriate.

Section 145(f) of the DGCL provides that the indemnification and
advancement of expenses provided by, or granted pursuant to, the other
subsections of Section 145 shall not be deemed exclusive of any other rights to
which those seeking indemnification or advancement of expenses may be entitled
under any bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in such person's official capacity and as to action
in another capacity while holding such office.

Section 145(g) of the DGCL provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of his or her status as such, whether or
not the corporation would have the power to indemnify such person against such
liability under the provisions of Section 145.

Section 145(j) of the DGCL provides that the indemnification and
advancement of expenses provided by, or granted pursuant to, Section 145 shall,
unless otherwise provided when authorized or ratified, continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

II-2


CERTIFICATE OF INCORPORATION

The Certificate of Incorporation provides that a director of the Company
shall not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability for
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided for in Section 174 of the DGCL. If the DGCL is amended to authorize
the further elimination or limitation of the liability of directors, then the
liability of a director of the Company, in addition to the limitation on
personal liability described above, shall be limited to the fullest extent
permitted by the amended DGCL. Further, any repeal or modification of such
provision of the Certificate of Incorporation by the stockholders of the Company
shall be prospective only, and shall not adversely affect any limitation on the
personal liability of a director of the Company existing at the time of such
repeal or modification.

BYLAWS

The Bylaws of the Company provide that the Company will indemnify and hold
harmless any director or officer of the Company to the fullest extent permitted
by applicable law, as in effect as of the date of the adoption of the Bylaws or
to such greater extent as applicable law may thereafter permit, from and against
all losses, liabilities, claims, damages, judgments, penalties, fines, amounts
paid in settlement and expenses (including attorneys' fees) whatsoever arising
out of any event or occurrence related to the fact that such person is or was a
director or officer of the Company and further provide that the Company may, but
is not required to, indemnify and hold harmless any employee or agent of the
Company or a director, officer, employee or agent of any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise who
is or was serving in such capacity at the written request of the Company;
provided, however, that the Company is only required to indemnify persons
serving as directors, officers, employees or agents of the Company for the
expenses incurred in a proceeding if such person has met the standards of
conduct that make it permissible under the laws of the State of Delaware for the
Company to indemnify the claimant for the amount claimed, but the burden of
proving such defense will be on the Company. The Bylaws further provide that,
in the event of any threatened, or pending action, suit or proceeding in which
any of the persons referred to above is a party or is involved and that may give
rise to a right of indemnification under the Bylaws, following written request
by such person, the Company will promptly pay to such person amounts to cover
expenses reasonably incurred by such person in such proceeding in advance of its
final disposition upon the receipt by the Company of (i) a written undertaking
executed by or on behalf of such person providing that such person will repay
the advance if it is ultimately determined that such person is not entitled to
be indemnified by the Company as provided in the Bylaws and (ii)satisfactory
evidence as to the amount of such expenses.

INSURANCE

The Company maintains liability insurance for the benefit of its directors
and officers.

(b) Financial Statement Schedules.

All schedules are omitted because they are not applicable or because the
required information is contained in the Financial Statements or Notes thereto.

Item 17. Undertakings

The undersigned Registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after
the effective date of this registration statement (or the most
recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the
information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume
of securities offered (if the total dollar value of securities
offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed
with the Securities and Exchange Commission pursuant to Rule
424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20% change in the maximum aggregate
offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement; and

(iii) to include any material information with respect to the plan of
distribution not previously disclosed in the registration
statement or any material change to such information in the
registration statement;

II-6


provided, however, that the undertakings set forth in clauses (i) and (ii) above
do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3,
and the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to the
Commission by Quanta Services, Inc. pursuant to Section 13 or 15(d) of the
Securities and Exchange Act of 1934 that are incorporated by reference in this
registration statement.

(2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering; and

(4) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(5) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit, or proceeding) is asserted by
such director, officer, or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

(6) The undersigned Registrant hereby undertakes that:

(i) For the purposes of determining any liability under the
Securities Act of 1933, the information omitted from the form of
prospectus filed as part of this Registration Statement in
reliance upon Rule 430A and contained in a form of prospectus
filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of
this Registration Statement as of the time it was declared
effective.

(ii) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form
of prospectus shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such new securities at that time shall be deemed to be the
initial bona fide offering thereof.
