                                    SUMMARY

  The following summary highlights selected information about us. It does not
contain all of the information that is important to you. You should carefully
read this entire prospectus supplement and accompanying prospectus and the
other documents to which those documents refer you. In addition, you should
carefully consider the factors set forth under the caption "Risk Factors."
Unless otherwise indicated, dollar amounts over $1 million have been rounded
to one decimal place and dollar amounts less than $1 million have been rounded
to the nearest thousand.

                                  Our Company

We provide communications services to business and residential customers in
the Midwestern and Rocky Mountain regions of the United States. We offer
local, long distance, Internet access, data, voice mail and paging services,
from a single company on a single bill. We believe we are the first company in
many of our markets to offer one-stop shopping for communications services
tailored to customers' specific needs.

Our approach makes it easier for both our business and our residential
customers to satisfy their communications needs. It also allows businesses to
receive customized services, such as competitive long distance pricing and
enhanced calling features, that might not otherwise be directly available on a
cost-effective basis. As of March 31, 1999, we served over 494,700 local lines
in 408 cities and towns and have a combined total of 488 switches and central
office locations.

In addition to our core business of providing competitive local, long distance
and related communications services, we also derive revenue from:

 .  sale of advertising space in telephone directories

 .  traditional local telephone company services in east central Illinois and
   southeast South Dakota

 .  special access, private line and data services

 .  communications network maintenance services

 .  telephone equipment sales, leasing, service and installation

 .  video services

 .  telemarketing services

 .  computer networking services

 .  other communications services, including cellular, operator, payphone,
   mobile radio, paging services and Web site development and hosting

We plan to derive revenues from high-speed digital access and data services
using Digital Subscriber Line and other technologies.

In most of our markets, we compete with the existing local phone company by
leasing its lines and switches. In other markets, primarily in east central
Illinois and southeast South Dakota, we operate our own lines and switches. We
provide long distance services by using our own communications network
facilities and leasing capacity from long distance and local communications
providers. We are constructing fiber optic communications networks in Iowa,
Illinois, Wisconsin, Indiana, Missouri, Michigan, Minnesota, South Dakota,
North Dakota, Colorado and Wyoming to carry additional communications traffic
on our own network.

                                 Our Strategy

We want to be the leading and most admired provider of communications services
in our markets. To achieve this goal, we are:

 .  aggressively capturing customer share and generating revenue using leased
   communications network capacity

 .  concurrently building our own communications network

 .  migrating customers to our communications network to provide enhanced
   services and to reduce our operating costs

The principal elements of our business strategy are to:

Provide integrated communications services. We believe we can rapidly
penetrate our target markets and build customer loyalty by providing an
integrated product offering to business and residential customers.
                                      S-1
<PAGE>


Build customer share through branding. We believe we will create and strengthen
brand awareness in our target markets by branding our communications services
with the trade name McLeodUSA in combination with the distinctive black-and-
yellow motif of our telephone directories.

Provide outstanding customer service. Our customer service representatives are
available 24 hours a day, seven days a week, to answer customer calls. Our
customer-focused software and systems allow our representatives immediate
access to our customer and network data, enabling a rapid and effective
response to customer requests.

Emphasize small and medium sized businesses. We primarily target small and
medium sized businesses because we believe we can rapidly capture customer
share by providing face-to-face business sales and strong service support to
these customers.

Expand our fiber optic communications network. We are building a state-of-the-
art fiber optic communications network to deliver multiple services and reduce
operating costs.

Expand our intra-city fiber optic communications network. Within selected
cities, we plan to extend our network directly to our customers' locations.
This will allow us to provide expanded services and reduce the expense of
leasing communications facilities from the existing local telephone company.

Explore acquisitions and strategic alliances. We plan to pursue acquisitions,
joint ventures and strategic alliances that expand or complement our business.

Leverage proven management team. Our executive management team consists of
veteran telecommunications managers who successfully implemented similar
customer-focused telecommunications strategies in the past.

                                ----------------
As of June 30, 1999, based on our business plan, capital requirements and
growth projections as of that date, we estimated that we would require
approximately $1.4 billion through 2001 to fund our planned capital
expenditures and operating expenses. Our estimated aggregate capital
requirements include the projected cost of:

 .  building our fiber optic communications network, including intra-city fiber
   optic networks
 .  expanding operations in existing and new markets
 .  developing wireless services
 .  funding general corporate expenses
 .  integrating acquisitions
 .  constructing, acquiring, developing or improving telecommunication assets

We expect to use the following to address our capital needs:
 .  approximately $   million in net proceeds from the sale of the Series A
   preferred stock and the  % Senior Notes due 2009
 .  approximately $475.0 million of cash and investments on hand at June 30,
   1999
 .  projected operating cash flow
 .  additional issuances of debt or equity securities

Our estimate of future capital requirements is a forward-looking statement
within the meaning of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. The actual amount and timing of our future
capital requirements is subject to risks and uncertainties and may differ
materially from our estimates. Accordingly, we may need additional capital to
continue to expand our markets, operations, facilities, network and services.
See "Risk Factors--Failure to Raise Necessary Capital Could Restrict Our
Ability to Develop Our Network and Services and Engage in Strategic
Acquisitions."

                                ----------------
Our principal executive offices are located at McLeodUSA Technology Park, 6400

                                   preference payable quarterly on each  ,  ,  , and   ,
                                   commencing on    , 1999. Dividends will accrue from the date
                                   of the original issuance of the Series A preferred stock. Any
                                   dividend on the Series A preferred stock shall be, at our option,
                                   payable (1) in cash or (2) through the issuance of a number of
                                   shares of our Class A common stock equal to the dividend amount
                                   divided by the Discounted Current Market Value.
                                   For the foreseeable future, we intend to pay these dividends solely in
                                   shares of Class A common stock. If, in the future, we were to consider
                                   paying cash dividends on the Series A preferred stock we would have to
                                   comply with the restrictions contained in the indentures governing our
                                   outstanding indebtedness. See "Risk Factors--We Are Restricted from
                                   Paying Cash Dividends" and "Description of the Series A Preferred
                                   Stock--Dividends."
Conversion into Class A Common     Series A preferred stock is convertible at the option of its holder,
 Stock...........................  unless previously redeemed, at any time after the issue date, into
                                   shares of our Class A common stock at a conversion rate of
                                   shares of Class A common stock for each share of Series A preferred
                                   stock (representing a conversion price of $    per share of
                                   Class A common stock), subject to adjustment in certain events.
                                   In addition, if on or after     , 2002, the closing price of our
                                   Class A common stock has equaled or exceeded 135% of the
                                   Conversion Price for at least 20 out of 30 consecutive days on which
                                   the Nasdaq National Market is open for the transaction of business,
                                   we will have the option to convert all the Series A preferred
                                   stock into Class A common stock at the then current conversion rate.

                                   of   % of the liquidation preference, plus accumulated and
                                   unpaid dividends to the redemption date, on or after     ,
                                   2001, but prior to     , 2002, if the closing price of our
                                   Class A common stock equals or exceeds 150% of the conversion
                                   price, currently equal to $    per share, for a specified trading
                                   period, which we refer to as the provisional redemption. In addition

                                    preferred stock may be redeemed, at our
                                    option, initially at a redemption price of
                                      % of the liquidation preference and
                                    thereafter at prices declining to 100% on
                                    and after     , plus in each case, all

                                 Holdings, Inc.

  On June 1, 1999, we entered into an Agreement and Plan of Merger with Access

  The operations statement data and other financial data in the table include
the operations of these companies beginning on the dates they were acquired.
The balance sheet data in the table include the financial position of these
companies at the end of the periods presented, beginning with the period in
which they were acquired. These acquisitions affect the comparability of the
financial data for the periods presented.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the following table has been
adjusted to reflect the two-for-one stock split.

  The pro forma information presented in the operations statement data and
other financial data in the table reflects the operations of Ovation as if the
Ovation acquisition had occurred on January 1, 1998 and the pro forma
information in the balance sheet data in the table includes Ovation's financial
position as of December 31, 1998.

  The pro forma information presented in the operations statement data and
other financial data in the table includes the effects of the issuance of $300
million principal amount of our 8 3/8% senior notes in March 1998, $300 million
principal amount of our 9 1/2% senior notes in October 1998 and $500 million
principal amount of the 8 1/8% senior notes in February 1999 as if they had
occurred at the beginning of 1998 and the pro forma information presented in
the balance sheet data in the table includes the effects of the issuance of the
8 1/8% senior notes as if it had occurred at the end of 1998.

  The ratio of earnings to fixed charges and preferred stock dividends is
calculated as follows: earnings consist of net loss before income taxes plus
fixed charges (excluding capitalized interest). Fixed charges consist of
interest on all debt (including capitalized interest), amortization of debt
discount and deferred loan costs and the portion of rental expense that is
representative of the interest component of rental expense (deemed to be one-
third of rental expense which management believes is a reasonable approximation
of the interest component). Preferred stock dividends means the amount of pre-
tax earnings that is required to pay the dividends on outstanding preferred
stock. We had no shares of preferred stock outstanding during any of the
periods presented. For each of the years ended December 31, 1994, 1995, 1996,
1997 and 1998, earnings were insufficient to cover fixed charges by $11.4
million, $11.4 million, $22.6 million, $84.4 million and $135.5 million,
respectively. For the three months ended March 31, 1998 and 1999, earnings were
insufficient to cover fixed charges by $32 million and $51.7 million,
respectively. On a pro forma basis, earnings would not have been sufficient to

(1) EBITDA consists of operating loss before depreciation, amortization and
    other nonrecurring operating expenses. We have included EBITDA data because
    it is a measure commonly used in the industry. EBITDA is not a measure of
    financial performance under generally accepted accounting principles and
    should not be considered an alternative to net income as a measure of
    performance or to cash flows as a measure of liquidity.

                                  RISK FACTORS

  You should carefully consider the following risk factors and the other
information in this prospectus supplement before investing in our securities.
You should also consider the additional information set forth in our SEC
reports on Forms 10-K, 10-Q and 8-K and in the other documents considered a
part of this prospectus supplement and accompanying prospectus. See "Where You
Can Find More Information."

Fluctuations in the Market Price of Our Class A Common Stock May Make it More
Difficult for Us to Raise Capital.

  The market price of our Class A common stock is extremely volatile and has
fluctuated over a wide range. These fluctuations may impair our ability to
raise capital by offering equity securities. The market price may continue to
fluctuate significantly in response to various factors, including:

  . market conditions in the industry

  . announcements or actions by competitors

  . low trading volume

  . sales of large amounts of our Class A common stock in the public market
    or the perception that such sales could occur

  . quarterly variations in operating results or growth rates

  . changes in estimates by securities analysts

  . regulatory and judicial actions

  . general economic conditions

We May Not Be Able to Successfully Integrate Acquired Companies into Our
Operations, Which Could Slow Our Growth.

  The integration of acquired companies into our operations involves a number
of risks, including:

  . difficulty integrating new operations and personnel

  . diversion of management attention

  . potential disruption of ongoing business

  . inability to retain key personnel or customers

  . inability to successfully incorporate new assets and rights into our
    service offerings

  . inability to maintain uniform standards, controls, procedures and
    policies

  . impairment of relationships with employees, customers or vendors

  Failure to overcome these risks or any other problems encountered in
connection with acquisition transactions could slow our growth or lower the
quality of our services, which could reduce customer demand and adversely
affect our business.

Continued Rapid Growth of Our Network, Services and Subscribers Could Be Slowed
if We Cannot Manage this Growth.

  We have rapidly expanded and developed our network, services and subscriber
base. For example, we recently announced plans to offer high-speed digital
access and data services. Our expansion and development have placed and will
continue to place significant demands on our management, operational and
financial systems and procedures and controls. We may not be able to manage our
anticipated growth effectively, which would adversely affect our business,
results of operations and financial condition.

Further expansion and development will depend on a number of factors,
including:

  . cooperation of the existing local telephone companies

  . regulatory, judicial and governmental developments

  . changes in the competitive climate in which we operate

  . development of customer billing, order processing and network management
    systems

  . availability of financing

  . technological developments

  . availability of rights-of-way, building access and antenna sites

  . existence of strategic alliances or relationships

  . emergence of future opportunities

                                      S-10
<PAGE>

  We will need to continue to improve our operational and financial systems and
our procedures and controls as we grow. We must also develop, train and manage
our employees.

We Expect to Incur Significant Losses Over the Next Several Years.

  If we do not become profitable in the future, the value of our Class A common
stock may fall and we could have difficulty obtaining funds to continue our
operations. We have incurred net losses every year since we began operations.
Since January 1, 1994, our net losses have been as follows:

</TABLE>

We expect to incur net losses during the next several years while we develop
our businesses, expand our fiber optic communications network and develop
wireless services.

Failure to Raise Necessary Capital Could Restrict Our Ability to Develop Our
Network and Services and Engage in Strategic Acquisitions.

  We need significant capital to continue to expand our operations, facilities,
network and services. We cannot assure you that our capital resources will
permit us to fund our planned network deployment and operations or achieve
operating profitability. Our failure to generate or raise sufficient funds may
require us to delay or abandon some of our expansion plans or expenditures,
which could adversely affect our business and competitive position.

  As of June 30, 1999, based on our business plan, capital requirements and
growth projections as of that date, we estimated that we would require
approximately $1.4 billion through 2001 to fund our capital expenditures and
operating expenses. Our estimated aggregate capital requirements include the
projected costs of:

  . building our fiber optic communications network, including intra-city
    fiber optic networks

  . expanding operations in existing and new markets

  . developing wireless services

  . funding general corporate expenses

  . integrating acquisitions

  . constructing, acquiring, developing or improving telecommunications
    assets

  Our estimate of future capital requirements is a forward-looking statement
within the meaning of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. The actual amount and timing of our future
capital requirements may differ substantially from our estimate due to factors
such as:

  . strategic acquisition costs and effects of acquisitions on our business
    plan, capital requirements and growth projections

  . unforeseen delays

  . cost overruns

  . engineering design changes

  . changes in demand for our services

  . regulatory, technological or competitive developments

  . new opportunities

  We also expect to evaluate potential acquisitions, joint ventures and
strategic alliances on an ongoing basis. We may require additional financing if
we pursue any of these opportunities.

  We may meet any additional capital needs by issuing additional debt or equity
securities or borrowing funds from one or more lenders. We cannot assure you
that we will have timely access to additional financing sources on acceptable
terms. If we do not have such access, we may not be able to expand our markets,
operations, facilities, network and services through acquisitions as we intend.

                                      S-11
<PAGE>

Our High Level of Debt Could Limit Our Flexibility in Responding to Business
Developments and Put Us at a Competitive Disadvantage.

  We have substantial debt, which could adversely affect us in a number of
ways, including:

  . limiting our ability to obtain necessary financing in the future

  . limiting our flexibility to plan for, or react to, changes in our
    business

  . requiring us to use a substantial portion of our cash flow from
    operations to pay our debt obligations rather than for other purposes,
    such as working capital or capital expenditures

  . making us more highly leveraged than some of our competitors, which may
    place us at a competitive disadvantage

  . making us more vulnerable to a downturn in our business

  As of March 31, 1999, we had $1.8 billion of long-term debt and $785.4
million of stockholders' equity. As a result, we expect our fixed charges to
exceed our earnings for the foreseeable future.

Covenants in Debt Instruments Restrict Our Capacity to Borrow and Invest, Which
Could Impair Our Ability to Expand or Finance Our Operations.

  The indentures governing the terms of our long-term debt impose operating and
financial restrictions that limit our discretion on some business matters,
which could make it more difficult for us to expand, finance our operations or
engage in other business activities that may be in our interest. These
restrictions limit or prohibit our ability to:

  . incur additional debt

  . pay dividends or make other distributions

  . make investments or other restricted payments

  . enter into sale and leaseback transactions

  . pledge or mortgage assets or otherwise create liens

  . enter into transactions with related persons

  . sell assets

  . consolidate, merge or sell all or substantially all of our assets

If we fail to comply with these restrictions, all of our long-term debt could
become immediately due and payable.

Our Ability to Pay Cash Dividends is Restricted.

  We have never paid any cash dividends. We do not anticipate paying any cash
dividends for the foreseeable future. The indentures governing our debt
restrict our ability to pay cash dividends. You should not expect that cash
dividends will be paid on the shares of our Series A preferred stock or on the
shares of our Class A common stock that you may acquire upon the conversion of
the Series A preferred stock.

Our Dependence on Regional Bell Operating Companies to Provide Most of Our
Communications Services Could Make it Harder for Us to Offer Our Services at a
Profit.

  We depend on the regional Bell operating companies to provide most of our
core local and some of our long distance services. Today, without using the
communications facilities of these companies, we could not provide bundled
local and long distance services to most of our customers. Because of this
dependence, our communications services are highly susceptible to changes in
the conditions for access to these facilities and we may therefore have
difficulty offering our services at profitable and competitive rates.

  U S WEST Communications, Inc., Ameritech Corporation and Southwestern Bell
Telephone Company are our primary suppliers of local lines to our customers and
communications services that allow us to transfer and connect calls. Their
communications facilities allow us to provide (1) local service, (2) long
distance service and (3) private lines dedicated to our customers' use. If
these or other companies deny or limit our access to their communications
network elements or wholesale services, we may not be able to offer profitable
communications services.


                                      S-12
<PAGE>

  Our plans to provide local service using our own communications network
equipment also depend on the regional Bell operating companies. In order to
interconnect our network equipment and other communications facilities to
network elements controlled by the regional Bell operating companies, we must
first negotiate and enter into interconnection agreements with them.
Interconnection obligations imposed on the regional Bell operating companies by
the Telecommunications Act of 1996 have been, and continue to be, subject to a
variety of legal proceedings, which could affect our ability to obtain
interconnection agreements on acceptable terms. We cannot assure you that we
will succeed in obtaining interconnection agreements on terms that would permit
us to offer local services using our own communications network facilities at
profitable and competitive rates.

Actions by U S WEST May Make it More Difficult for Us to Offer Our
Communications Services.

  U S WEST has introduced several measures that may make it more difficult for
us to offer our communications services. For example, in February 1996, U S
WEST filed tariffs and other notices with the public utility commissions in its
fourteen-state service region to limit future Centrex access to its switches.
Centrex access allows us to aggregate lines, have control over several
characteristics of those lines and provide a set of standard features on those
lines. We use U S WEST's Centrex services to provide most of our local
communications services in U S WEST's service territories.

  In January 1997, U S WEST also proposed interconnection surcharges in several
of the states in its service region, which would increase our costs of
providing communications services in those states.

  We have challenged or are challenging these actions by U S WEST before the
FCC or applicable state public utility commissions. We cannot assure you we
will succeed in our challenges to these or other actions by U S WEST that would
prevent or deter us from using U S WEST's Centrex service or communications
network elements. If U S WEST successfully withdraws or limits our access to
Centrex services in any jurisdiction, we may not be able to offer
communications services in that jurisdiction, which could adversely affect our
business.

  We anticipate that U S WEST will also pursue legislation in states within our
target market area to reduce state regulatory oversight over its rates and
operations. If adopted, these initiatives could make it more difficult for us
to challenge U S WEST's actions in the future.

Competition in the Communications Services Industry Could Cause Us to Lose
Customers and Revenue and Could Make it More Difficult for Us to Enter New
Markets.

  We face intense competition in all of our markets. This competition could
result in loss of customers and lower revenue for us. It could also make it
more difficult for us to enter new markets. Existing local telephone companies,
including U S WEST, Ameritech, Southwestern Bell and GTE, currently dominate
their local telecommunications markets. Three major competitors, AT&T, MCI
WorldCom and Sprint, dominate the long distance market. Hundreds of other
companies also compete in the long distance marketplace. AT&T, MCI WorldCom and
Sprint also offer local telecommunications services in many locations.

  We also compete with other communications services companies which, like us,
compete with the existing local telephone companies in some markets.

  Other competitors may include cable television companies, providers of
communications network facilities dedicated to particular customers, providers
of digital access and data services, microwave and satellite carriers, wireless
telecommunications providers, private networks owned by large end-users, and
telecommunications management companies.

  These and other firms may enter the markets where we focus our sales efforts.
Many of our existing and potential competitors have financial and other
resources far greater than our own. In addition, the trend toward mergers and
strategic alliances in the communications industry may strengthen some of our
competitors, which could put us at a significant competitive disadvantage.

We May Not Succeed in Developing or Making a Profit from Wireless Services.

  Our proposal to offer wireless services involves a high degree of risk and
will impose significant

                                      S-13
<PAGE>

demands on our management and financial resources. Developing wireless services
may require us to, among other things, spend substantial time and money to
acquire, build and test a wireless infrastructure and enter into roaming
arrangements with wireless operators in other markets. We may not succeed in
developing wireless services. Even if we spend substantial amounts to develop
wireless services, we may not make a profit from wireless operations.

  Our ability to successfully offer wireless services will also depend on a
number of factors beyond our control, including:

  . changes in communications service rates charged by other companies

  . changes in the supply and demand for wireless services due to competition
    with other wireline and wireless operators in the same geographic area

  . changes in the federal, state or local regulatory requirements affecting
    the operation of wireless systems

  . changes in wireless technologies that could render obsolete the
    technology and equipment we choose for our wireless services

Competition in the Wireless Telecommunications Industry Could Make it Harder
for Us to Successfully Offer Wireless Services.

  The wireless telecommunications industry is experiencing increasing
competition and significant technological change. This will make it harder for
us to gain a share of the wireless communications market. We expect up to eight
wireless competitors in each of our target wireless markets. We could face
additional competition from mobile satellite services.

  Many of our potential wireless competitors have financial and other resources
far greater than our own and have more experience testing new or improved
products and services. In addition, several wireless competitors operate or
plan to operate, wireless telecommunications systems that encompass most of the
United States, which could give them a significant competitive advantage,
particularly if we only offer regional wireless services.

The Success of Our Communications Services Will Depend on Our Ability to Keep
Pace with Rapid Technological Changes in Our Industry.

  Communications technology is changing rapidly. These changes influence the
demand for our services. We need to be able to anticipate these changes and to
develop new and enhanced products and services quickly enough for the changing
market. This will determine whether we can continue to increase our revenues
and number of subscribers and be competitive. Failure to adapt to these changes
may adversely affect our business.

The Loss of Key Personnel Could Weaken Our Technical and Operational Expertise,
Delay Our Introduction of New Services or Entry into New Markets and Lower the
Quality of Our Service.

  We may not be able to attract, develop, motivate and retain experienced and
innovative personnel. There is intense competition for qualified personnel in
our business. The loss of the services of key personnel, or the inability to
attract additional qualified personnel, could cause us to make less successful
strategic decisions, which could hinder the introduction of new services or the
entry into new markets. We could also be less prepared for technological or
marketing problems, which could reduce our ability to serve our customers and
lower the quality of our services. As a result, our financial condition could
worsen.

  Our future success depends on the continued employment of our senior
management team, particularly Clark E. McLeod, our Chairman and Chief Executive
Officer, and Stephen C. Gray, our President and Chief Operating Officer. We do
not have term employment agreements with these employees.

Failure to Obtain and Maintain Necessary Permits and Rights-of-Way Could Delay
Installation of Our Networks and Interfere with Our Operations.

  To obtain access to rights-of-way needed to install our fiber optic cable, we
must reach agreements with state highway authorities, local governments,
transit authorities, local telephone companies, other utilities, railroads,
long distance carriers and other parties. The failure to obtain or maintain any
rights-of-way could delay our planned network expansion, interfere with our
operations and

                                      S-14
<PAGE>

adversely affect our business. For example, if we lose access to a right-of-
way, we may need to spend significant sums to remove and relocate our
facilities.

Government Regulation May Increase Our Cost of Providing Services, Slow Our
Expansion into New Markets and Subject Our Services to Additional Competitive
Pressures.

  Our facilities and services are subject to federal, state and local
regulation. The time and expense of complying with these regulations could slow
down our expansion into new markets, increase our costs of providing services
and subject them to additional competitive pressures. One of the primary
purposes of the Telecommunications Act of 1996 was to open the local telephone
services market to competition. While this has presented us with opportunities
to enter local telephone markets, it also has provided important benefits to
the existing local telephone companies, such as the ability, under specified
conditions, to provide out-of-region long distance service to customers in
their respective regions. In addition, we need to obtain and maintain licenses,
permits and other regulatory approvals in connection with some of our services.
Any of the following could adversely affect our business:

  . failure to maintain proper federal and state tariffs

  . failure to maintain proper state certifications

  . failure to comply with federal, state or local laws and regulations

  . failure to obtain and maintain required licenses and permits

  . burdensome license or permit requirements to operate in public rights-of-
    way

  . burdensome or adverse regulatory requirements

Our Management and Principal Stockholders Can Control McLeodUSA and May Have
Different Interests Than Those of Other Stockholders.

  As of July 1, 1999, Interstate Energy Corporation, M/C Investors L.L.C.,
Media/Communications Partners III Limited Partnership, Richard A. Lumpkin and
various trusts for the benefit of his family, Clark and Mary McLeod, and our
directors and executive officers beneficially owned approximately 40% of our
outstanding Class A common stock. These stockholders can collectively control
management policy and may be able to control corporate actions requiring a
stockholder vote, including election of the board of directors. Conflicts of
interest may arise between the interests of these stockholders and our other
stockholders. For example, the fact that these stockholders hold so much Class
A common stock could make it more difficult for a third party to acquire us.
You should expect these stockholders to resolve any conflicts in their favor.

Computer Systems May Malfunction and Interrupt Our Services if We and Our
Suppliers Do Not Attain Year 2000 Readiness.

  We and our major suppliers of communications services and network elements
rely greatly on computer systems and other technological devices. These may not
be capable of recognizing January 1, 2000 or subsequent dates. This problem
could cause any or all of our systems or services to malfunction or fail.

  We are reviewing our computer systems and programs and other technological
devices to determine which are not capable of recognizing the Year 2000 and to
verify system readiness for the millennium date. The review covers all of our
operations and is centrally managed. This review may not be sufficient,
however, to prevent interruptions to our systems and services.

  Some of our critical operations and services depend on other companies. For
example, we depend on the existing local telephone companies, primarily the
regional Bell operating companies, to provide most of our local and some of our
long distance services. To the extent U S WEST, Ameritech or Southwestern Bell
fail to address Year 2000 issues which might interfere with their ability to
fulfill their obligations to us, it could interfere with our operations. If we,
our major vendors, our material service providers or our customers fail to
address Year 2000 issues in a timely manner, our business, results of
operations and financial condition could be adversely affected.

Secondary Sales of Our Class A Common Stock in the Public Market Could
Adversely Affect Our Stock Price.

  We cannot assure you that the market price of our Class A common stock will
not fluctuate or decline significantly in the future as a consequence of sales
by existing stockholders. Accordingly, there can be no assurance that the
market price of the Class A common stock will exceed the Conversion Price of
the Series A preferred stock.

  As of July 1, 1999, after giving effect to the two-for-one stock split
announced June 30, 1999, there were outstanding:

  . 150.4 million shares of our Class A common stock

  . options to purchase 26.7 million shares of our Class A common stock

  . 62.8 million shares of Class A common stock owned by Interstate Energy,
    M/C Investors, Media/Communications Partners III, Richard A. Lumpkin and
    various trusts for the benefit of his family, Clark and Mary McLeod, and
    our directors and executive officers, all of which were eligible for sale
    in the public market either in accordance with Rule 144 under the
    Securities Act of 1933 or otherwise.

Payment of Dividends in Shares of Class A Common Stock May Not Result in Stated
Dividend Yield.

  In the event dividends are paid in shares of Class A common stock, the number
of shares of Class A common stock to be issued on each dividend payment date
will be determined by dividing the total dividend to be paid on each share of
Series A preferred stock by the Discounted Current Market Value, as defined
under "Description of the Series A Preferred Stock-- Dividends." If the market
price of Class A common stock applicable in determining the Discounted Current
Market Value is higher than the market price for the Class A common stock on
the dividend payment date and you sell your Class A common stock at such lower
price, your actual dividend yield could be lower than the stated dividend yield
on the Series A preferred stock. In addition, you are likely to incur
commissions and
other transaction costs in connection with the sale of such Class A common
stock.

The Series A Preferred Stock is Subordinated to All Our Liabilities.

  In the event of our bankruptcy, liquidation or winding-up, our assets will be
available to pay obligations on the Series A preferred stock only after all
indebtedness and other liabilities, including our existing senior notes, and
all subsequent series of preferred stock which rank senior to the Series A
preferred stock, have been paid. There may not be sufficient assets remaining
to pay amounts due on any or all of the Series A preferred stock then
outstanding. As of March 31, 1999, the Series A preferred stock would have been
junior in right of payment to our $1.8 billion of long-term debt, of which
$325.0 million is attributed to our subsidiaries. The Series A preferred stock
will also be junior in right of payment to our   % Senior Notes due 2009 being
offered concurrently with the Series A preferred stock.

Purchasers of Our Series A Preferred Stock Who Convert Their Shares to Class A
Common Stock Will Incur Immediate Dilution.

  Persons purchasing Series A preferred stock who convert their shares into
Class A common stock will incur immediate net tangible book value dilution of
$   per share, assuming that they converted all of their shares of Series A
preferred stock on March 31, 1999. Our existing stockholders will receive an
immediate increase in net tangible book value of $   per share. The per share
amounts give effect to the two-for-one stock split announced June 30, 1999.

Our Series A Preferred Stock is a New Issue of Securities and Has Never Been
Publicly Traded.

  Prior to this offering there has been no trading market for the Series A
preferred stock. We will seek to have the Series A preferred stock listed for
quotation on the Nasdaq National Market; however, no assurance can be given as
to the liquidity of, or trading market for, the Series A preferred stock. If an
active market for the Series A preferred stock fails to develop or be
sustained, the trading price of such Series A preferred stock could be
materially adversely affected.

                                USE OF PROCEEDS

  We will use the net proceeds from the sale of Series A preferred stock along
with funds available from prior offerings and from other financing sources: (1)
to fund development and construction costs of our fiber optic network,
including intra-city fiber optic networks, and construction, acquisition,
development and improvement of telecommunications assets; (2) to fund market
expansion activities in existing and new markets as well as acquisitions, joint
ventures and strategic alliances; (3) to fund development, construction and
operations necessary to include wireless services as part of our communications
services; and (4) for additional working capital and other general corporate
purposes, including funding operating deficits and net losses.

                                DIVIDEND POLICY

  We have never declared or paid any cash dividends on our capital stock and do
not anticipate paying cash dividends in the foreseeable future. The indentures
that govern the terms of our debt restrict our ability to pay cash dividends.
Future dividends on our Class A common stock, if any, will be at the discretion
of our board of directors and will depend upon, among other things, our
operations, capital requirements and surplus, general financial condition,
contractual restrictions in financing agreements and such other factors as our
board of directors may deem relevant. Although we have the option under the
Certificate of Designations of the Series A preferred stock of paying dividends
in cash, because of the restrictions contained in our indentures, we do not
expect to pay dividends in cash in the foreseeable future. Rather, we expect to
pay such dividends in shares of our Class A common stock.

               SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA

  The information in the following table is based on historical financial
information included in our prior SEC filings, including our annual report on
Form 10-K for the fiscal year ended December 31, 1998. The following summary
financial information should be read in connection with this historical
financial information, including the notes which accompany such financial
information. This historical financial information is considered a part of this
document. See "Where You Can Find More Information." Our audited historical
financial statements as of December 31, 1998 and 1997, and for each of the
three years ended December 31, 1998 were audited by Arthur Andersen LLP,
independent public accountants.

  The information in the table on the following page reflects consolidated
financial information for the following companies we have acquired:

  The operations statement data and other financial data in the table include
the operations of these companies beginning on the dates they were acquired.
The balance sheet data in the table include the financial position of these
companies at the end of the periods presented, beginning with the period in
which they were acquired. These acquisitions affect the comparability of the
financial data for the periods presented.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the following table has been
adjusted to reflect the two-for-one stock split.

  The pro forma information presented in the operations statement data and
other financial data in the table reflects the operations of Ovation as if the
Ovation acquisition had occurred on January 1, 1998 and the pro forma
information in the balance sheet data in the table includes Ovation's financial
position as of December 31, 1998.

  The pro forma information presented in the operations statement data and
other financial data in the table includes the effects of the issuance of $300
million principal amount of our 8 3/8% senior notes in March 1998, $300 million
principal amount of our 9 1/2% senior notes in October 1998 and $500 million
principal amount of the 8 1/8% notes in February 1999 as if they had occurred
at the beginning of 1998 and the pro forma information presented in the balance
sheet data in the table includes the effects of the issuance of the 8 1/8%
notes as if it had occurred at the end of 1998.

  The ratio of earnings to fixed charges and preferred stock dividends is
calculated as follows: earnings consist of net loss before income taxes plus
fixed charges (excluding capitalized interest). Fixed charges consist of
interest on all debt (including capitalized interest), amortization of debt
discount and deferred loan costs and the portion of rental expense that is
representative of the interest component of rental expense (deemed to be one-
third of rental expense which management believes is a reasonable approximation
of the interest component). Preferred stock dividends means the amount of pre-
tax earnings that is required to pay the dividends on outstanding preferred
stock. We had no preferred stock outstanding during any of the periods
presented. For each of the years ended December 31, 1994, 1995, 1996, 1997 and
1998, earnings were insufficient to cover fixed charges by $11.4 million, $11.4
million, $22.6 million, $84.4 million and $135.5 million, respectively. For the
three months ended March 31, 1998 and 1999, earnings were insufficient to cover
fixed charges by $32 million and $51.7 million, respectively. On a pro forma
basis, earnings would not have been sufficient to cover fixed charges by $188.6
and $61.7 million for the year ended December 31, 1998 and the three months
ended March 31, 1999, respectively.

(1) EBITDA consists of operating loss before depreciation, amortization and
    other nonrecurring operating expenses. We have included EBITDA data
    because it is a measure commonly used in the industry. EBITDA is not a
    measure of financial performance under generally accepted accounting
    principles and should not be considered an alternative to net income as a
    measure of performance or to cash flows as a measure of liquidity.

                            PRO FORMA FINANCIAL DATA

  The following unaudited pro forma financial information has been prepared to
give effect to:

 . the issuance of $300 million aggregate principal amount of our 8 3/8% senior
  notes in March 1998

 . the issuance of $300 million aggregate principal amount of our 9 1/2% senior
  notes in October 1998

 . the issuance of $500 million aggregate principal amount of our 8 1/8% senior
  notes in February 1999

 . our acquisition of Ovation Communications, Inc. in March 1999

  The Unaudited Pro Forma Condensed Consolidated Statements of Operations
reflects the Ovation acquisition using the purchase method of accounting, and
assumes that the Ovation acquisition and the issuance of the 8 3/8% senior
notes, the 9 1/2% senior notes and the 8 1/8% senior notes were consummated at
the beginning of 1998. The unaudited pro forma financial information is derived
from and should be read in conjunction with our consolidated financial
statements, Ovation's consolidated financial statements and the related notes
thereto incorporated by reference in this prospectus. The pro forma adjustments
are based upon available information and assumptions that management believes
to be reasonable. Depreciation and amortization were adjusted to include
amortization of intangibles acquired in the Ovation acquisition. The acquired
intangibles will be amortized over periods ranging from 3 to 30 years. For
purposes of this pro forma presentation, the issuance of the 8 3/8% senior
notes, the 9 1/2% senior notes and the 8 1/8% senior notes are collectively
referred to as the "Notes Offerings."

  The adjustments for the Ovation acquisition reflect the preliminary
allocation of the net purchase price of Ovation to the assets of Ovation,
including intangible assets, and record the payment of $121.3 million in cash
and the issuance of 11,193,234 shares of our Class A common stock (as adjusted
for the two-for-one stock split described below) valued at $16.88 per share (as
adjusted for the two-for-one stock split described below). The value of $16.88
per share represents the average closing price of our Class A common stock on
the Nasdaq National Market for the eleven trading days beginning five days
prior to the date the agreement was announced, January 7, 1999, and ending five
days after such announcement. The adjustments include the elimination of the
Ovation equity components, including common stock, treasury stock, other
capital and retained deficit.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the Pro Forma Financial Data
has been adjusted to reflect the two-for-one stock split.

  We have provided this unaudited pro forma financial data for informational
purposes only. This data does not necessarily indicate the operating results
that would have occurred had the Ovation acquisition been consummated at the
beginning of 1998, nor does it necessarily indicate future operating results or
financial position.

                  DESCRIPTION OF THE SERIES A PREFERRED STOCK

  The following is a summary of certain provisions of the Certificate of
Designations and the Series A preferred stock. Copies of the Certificate of
Designations and the form of Series A preferred stock share certificate are
available upon request at our address set forth under "Where You Can Find More
Information." This summary is not intended to be complete and is subject to,
and is qualified in its entirety by reference to, the Certificate of
Designations. The definitions of certain capitalized terms used in the
following summary that are not defined herein are defined in the Certificate of
Designations. For purposes of this description of the Series A preferred stock,
the words "McLeodUSA," "we," "our" or "us" refer to McLeodUSA Incorporated and
do not include its subsidiaries.

General

  At the consummation of this offering, we will issue 400,000 shares of our
   % Series A Cumulative Convertible Preferred Stock, $0.01 par value per
share, designated as "    % Series A Cumulative Convertible Preferred Stock."
When issued, the Series A preferred stock will be validly issued, fully paid
and nonassessable. The holders of the Series A preferred stock will have no
preemptive or preferential right to purchase or subscribe to stock,
obligations, warrants or any other of our securities of any class. We will seek
to have the Series A preferred stock approved for listing on the Nasdaq
National Market.

Ranking

  The Series A preferred stock will, with respect to dividend rights and rights
on liquidation, dissolution or winding-up, rank:

  .  junior to all our existing and future debt obligations

  .  junior to "Senior Stock," which is each class of our capital stock or
     series of preferred stock established after the Series A preferred stock
     by our board of directors that has terms which expressly provide that
     such class or series will rank senior to the Series A preferred stock

  .  on a parity with "Parity Stock," which is each class of capital stock or
     series of preferred stock established after the Series A preferred stock
     by our board of directors that has terms which expressly provide that
     such class or series will rank on a parity with the Series A preferred
     stock

  .  senior to "Junior Stock," which is all classes of our common stock,
     including our Class A common stock and Class B common stock, and any
     other class of our capital stock established after the Series A
     preferred stock by our board of directors whose terms do not expressly
     provide that such class or series ranks senior to, or on a parity with,
     our Series A preferred stock

  While any shares of Series A preferred stock are outstanding, we may not
authorize, create or increase the authorized amount of any class or series of
capital stock that ranks senior to the Series A preferred stock with respect to
the payment of dividends or amounts upon liquidation, dissolution or winding-up
without the consent of the holders of at least 66 2/3% of the outstanding
shares of Series A preferred stock. We may, however, without the consent of any
holder of Series A preferred stock, create additional classes of capital stock,
increase the authorized number of shares of preferred stock or issue series of
a stock that ranks on a parity with, or junior to, the Series A preferred stock
with respect, in each case, to the payment of dividends and amounts upon
liquidation, dissolution and winding-up. See "--Voting Rights."

Dividends

  Subject to the rights of any holders of Senior Stock and Parity Stock,
holders of shares of Series A preferred stock will be entitled to receive,
when, as and if declared by the board of directors out of funds of McLeodUSA
legally available for payment, cumulative dividends at the annual rate of    %
per share on the liquidation preference thereof of $1,000 per share of Series A
preferred stock (equivalent to $      per share

                                      S-25
<PAGE>

annually). Dividends on the Series A preferred stock will be payable quarterly
on        ,        ,         and          of each year commencing
               , 1999, at such annual rate and shall accrue from the most
recent date as to which dividends shall have been paid or, if no dividends have
been paid, from the date of the original issuance of the Series A preferred
stock. Each such dividend will be payable to holders of record as they appear
on our stock records at the close of business on the record date next preceding
such quarterly dividend payment date, which record dates will be established by
the board of directors but, in any event, will be not more than 60 days nor
less than 15 days before the respective quarterly dividend payment dates.
Dividends will be cumulative from such quarterly dividend payment date, whether
or not in any dividend period or periods there shall be funds of McLeodUSA
legally available for the payment of such dividends. Accumulations of dividends
on shares of Series A preferred stock will not bear interest. Dividends payable
on the Series A preferred stock for any period greater or less than a full
quarterly dividend period will be computed on the basis of a 360-day year
consisting of twelve 30-day months.

  Any dividend on the Series A preferred stock shall be, at the option of
McLeodUSA, payable (1) in cash or (2) through the issuance of shares of our
Class A common stock. If we pay dividends in shares of Class A common stock,
the number of shares of Class A common stock to be issued on each dividend
payment date will be determined by dividing the total dividend to be paid on
each share of Series A preferred stock by the applicable Discounted Current
Market Value (as defined below) of the Class A common stock. The transfer agent
is authorized and directed in the Certificate of Designations to aggregate any
fractional shares of Class A common stock that are issued as dividends, sell
them at the best available price and distribute the proceeds to the holders of
the Series A preferred stock in proportion to their respective interests. We
will pay the expenses of the transfer agent with respect to such sale,
including brokerage commissions. In the event the sale by the transfer agent of
such aggregated fractional interests would be restricted, McLeodUSA and the
transfer agent will agree upon other appropriate arrangements for the cash
realization of fractional interests. All shares of Class A common stock
distributed on the related dividend payment date in payment of dividends on the
Series A preferred stock will be freely transferable without restriction under
the Securities Act.

  The "Discounted Current Market Value" of the Class A common stock with
respect to a dividend payment date means the product of (x) 97% and (y) the
"Market Average Value" as of the record date relating to such dividend payment
date. The "Market Average Value" will equal the average of the daily closing
prices of the Class A common stock for the five consecutive Trading Days ending
on (and including) the fourth Trading Day prior to such dividend payment date.
The closing price for each Trading Day will be the last sales price on the
Nasdaq National Market, or the principal securities exchange or other
securities market on which the Class A common stock is then being traded.
"Trading Day" means any day on which the Class A common stock is traded for any
period on the Nasdaq National Market (or on the principal securities exchange
or other securities market on which the Class A common stock is then being
traded).

  No dividend will be declared or paid upon, or any sum set apart for the
payment of dividends upon, any outstanding share of the Series A preferred
stock with respect to any dividend period unless all dividends for all
preceding dividend periods have been declared and paid, or declared and a
sufficient sum set apart for the payment of such dividend, upon all outstanding
shares of Series A preferred stock.

   We will not (1) declare, pay or set apart funds for the payment of any
dividend or other distribution with respect to any Junior Stock or (2) redeem,
purchase or otherwise acquire for consideration any Junior Stock through a
sinking fund or otherwise, unless (A) all accrued and unpaid dividends with
respect to the Series A preferred stock and any Parity Stock at the time such
dividends are payable have been paid or funds have been set apart for payment
of such dividends and (B) sufficient funds have been paid or set apart for the
payment of the dividend for the current dividend period with respect to the
Series A preferred stock and any Parity Stock.

  No dividend will be declared or paid on any Parity Stock unless full
cumulative dividends have been paid on the Series A preferred stock for all
prior dividend periods; provided, however, if accrued dividends on the

                                      S-26
<PAGE>

Series A preferred stock for all prior dividend periods have not been paid in
full, then any dividend declared for any dividend period on the Series A
preferred stock and on any Parity Stock will be declared ratably in proportion
to accrued and unpaid dividends on the Series A preferred stock and such Parity
Stock.

  Notwithstanding anything herein to the contrary, we may declare and pay
dividends on Parity Stock or Junior Stock which are payable solely in shares of
Parity Stock or Junior Stock (in the case of Parity Stock) or of Junior Stock
(in the case of Junior Stock) or by the increase in the liquidation value of
Parity Stock or Junior Stock, as applicable, or repurchase, redeem or otherwise
acquire Junior Stock in exchange for Junior Stock and Parity Stock in exchange
for Parity Stock or Junior Stock.

  For the foreseeable future, we intend to pay all dividends on the Series A
preferred stock (except with respect to cash paid in lieu of fractional shares)
in shares of our Class A common stock. If, in the future, we were to consider
paying cash dividends on the Series A preferred stock we would have to comply
with the restrictions contained in the indentures governing our outstanding
indebtedness. See "Risk Factors--We Are Restricted from Paying Cash Dividends."

Redemption

Provisional Redemption

  We may redeem Series A preferred stock, upon not less than 30 nor more than
60 days' prior notice mailed by first-class mail to each holder's registered
address, at a redemption price of    % of the liquidation preference, plus
accumulated and unpaid dividends, if any, whether or not declared (including a
prorated dividend for any partial dividend period), to the redemption date (the
"Provisional Redemption Date"), on or after         , 2001, but prior to
       , 2002, if the closing price of our Class A common stock equals or
exceeds 150% of the Conversion Price for at least 20 Trading Days within any 30
Trading Day period. This type of redemption is a "Provisional Redemption."

  If we undertake a Provisional Redemption, the holders of shares of Series A
preferred stock that are called for redemption also will receive a payment
(referred to as the "additional payment") in an amount equal to the present
value of the aggregate value of the dividends that would thereafter have been
payable on the Series A preferred stock (whether or not such dividends have
been declared) for the period from the Provisional Redemption Date to       ,
2002 (which period is referred to as the "additional period"). The present
value will be calculated using the bond equivalent yield on U.S. Treasury notes
or bills having a term nearest in length to that of the additional period as of
the day immediately preceding the date on which a notice of Provisional
Redemption is mailed.

  We may effect any provisional redemption, in whole or in part, at our option,
by payment of the redemption price, including any additional payment, in cash,
through delivery of shares of Class A common stock or a combination thereof,
subject to applicable law, by delivering notice to the holders of the Series A
preferred stock not less than 30 nor more than 60 days prior to the scheduled
redemption date.

Optional Redemption

  Except under the foregoing circumstances for a Provisional Redemption, we may
not redeem the Series A preferred stock prior to            , 2002. Thereafter,
each share of the Series A preferred stock may be redeemed, at our option, in
whole or in part, at any time or from time to time, upon not less than 30 nor
more than 60 days' prior notice mailed by first-class mail to each holder's
registered address, at the following redemption prices, plus accumulated and
unpaid dividends, if any, to the date fixed for redemption (including a
prorated dividend for any partial dividend period), payable in cash.

                                      S-27
<PAGE>

  If redeemed during the 12-month period commencing on             (or, if such
date is not a date on which the Nasdaq National Market is open for business,
then on the next day the Nasdaq National Market is open for business) of the
years set forth below, the redemption prices shall be:

</TABLE>

  In the case of any partial optional redemption, selection of the Series A
preferred stock for redemption will be made by us in compliance with the
requirements of the principal national securities exchange, if any, on which
the Series A preferred stock is listed, or if the Series A preferred stock is
not listed on a national securities exchange, on a pro rata basis, by lot or
such other method as we, in our sole discretion, deem fair and appropriate;
provided, however, that we may redeem all the shares held by holders of fewer
than five shares (or all of the shares held by the holders who would hold fewer
than five shares as a result of such redemption) as we may determine.

  If any Provisional Redemption Date or other redemption date falls after a
dividend payment record date and prior to the related dividend payment date,
the holders of the Series A preferred stock at the close of business on such
record date will be entitled to receive the dividend payable on such shares on
the corresponding dividend payment date, notwithstanding the redemption of such
shares following such dividend payment record date. Except as provided for in
the preceding sentence, no payment or allowance will be made for accrued
dividends on any shares of Series A preferred stock called for redemption.

  Our ability to redeem the Series A preferred stock at our option is limited
by the terms of our outstanding indebtedness. We may not be able to redeem the
Series A preferred stock unless we simultaneously redeem or repay such
indebtedness.

Liquidation Preference

  Upon the voluntary or involuntary liquidation, dissolution or winding-up of
McLeodUSA, and subject to the rights of the creditors of McLeodUSA and holders
of Senior Stock and Parity Stock, each holder of Series A preferred stock will
be entitled to be paid, out of the assets of McLeodUSA available for
distribution to stockholders, an amount equal to the liquidation preference of
$1,000 per share of Series A preferred stock held by such holder, plus
accumulated and unpaid dividends thereon to the date fixed for liquidation,
dissolution or winding-up (including an amount equal to a prorated dividend for
the period from the last divided payment date to the date fixed for
liquidation, dissolution or winding-up) before any distribution is made on any
Junior Stock, including our Class A common stock. If, upon any voluntary or
involuntary liquidation, dissolution or winding-up of McLeodUSA, the amounts
payable with respect to the Series A preferred stock and all other Parity Stock
are not paid in full, the holders of the Series A preferred stock and the
Parity Stock will share equally and ratably in any distribution of the assets
of McLeodUSA in proportion to the respective amounts to which they are
entitled. After payment of the full amount of the liquidation preference of the
Series A preferred stock, and, if applicable, an amount equal to a prorated
dividend, the holders of shares of Series A preferred stock will not be
entitled to any further participation in any distribution of the assets of
McLeodUSA. However, neither the sale, conveyance, exchange or transfer (for
cash, shares of stock, securities or other consideration) of all or
substantially all of the property or assets of McLeodUSA nor the consolidation
or merger of McLeodUSA with, or into, one or more entities will be deemed to be
a liquidation, dissolution or winding-up of McLeodUSA.

  The Certificate of Designations will not contain any provision requiring
funds to be set aside to protect the liquidation preference of the Series A
preferred stock even though it is substantially in excess of the par value
thereof.

                                      S-28
<PAGE>

Voting Rights

  The holders of Series A preferred stock, except as otherwise required under
Delaware law or as provided in the Certificate of Designations, shall not be
entitled to vote on any matter required or permitted to be voted upon by our
stockholders. In exercising any such vote, each outstanding share of Series A
preferred stock will have one vote (excluding shares of Series A preferred
stock held by McLeodUSA or any entity controlled by McLeodUSA, which shares
will have no votes).

  The Certificate of Designations will provide that if dividends on the Series
A preferred stock are in arrears and unpaid for six or more dividend periods
(whether or not consecutive) then the holders of the outstanding shares of
Series A preferred stock, voting separately and as a class together with the
holders of any Parity Stock upon which like rights have been conferred and are
exercisable, will be entitled to elect to serve on the board of directors the
lesser of (x) two additional members to the board of directors or (y) that
number of directors constituting at least 25% of the members of the board of
directors, and the number of members of the board of directors will be
immediately and automatically increased by such number. Such voting rights of
the Series A preferred stock will continue until such time as all dividends in
arrears on the Series A preferred stock are paid in full, at which time the
term of any directors elected pursuant to the provisions of this paragraph
(subject to the right of holders of any other preferred stock to elect such
directors) shall terminate and the number of directors constituting the board
of directors will be immediately and automatically decreased by such number
(until the occurrence of any such subsequent event).

  The Certificate of Designations will also provide that, except as expressly
set forth above under "--Ranking," (1) the creation, authorization or issuance
of any shares of Junior Stock or Parity Stock, including the designation of a
series thereof within the existing class of Series A preferred stock, or (2)
the increase or decrease in the amount of authorized capital stock of any
class, including any preferred stock, shall not require the consent of the
holders of Series A preferred stock and shall not be deemed to affect adversely
the rights, preferences, privileges or voting rights of shares of Series A
preferred stock.

Conversion Rights

  Shares of Series A preferred stock will be convertible, in whole or in part,
at any time after the issue date, at the option of the holders thereof, into
shares of Class A common stock initially at the conversion price of $    per
share, subject to adjustment as described below ("Conversion Price"). The right
to convert shares of Series A preferred stock called for redemption will
terminate at the close of business on the relevant redemption date.

  We will have the option to convert all of the shares of Series A preferred
stock into shares of Class A common stock at the Conversion Price if, on or
after         , 2002, the closing price of our Class A common stock has equaled
or exceeded 135% of the Conversion Price for at least 20 out of 30 consecutive
days on which the Nasdaq National Market (or the principal securities exchange
or other securities market on which the Class A common stock is then being
traded) is open for the transaction of business.

  Conversion of shares of Series A preferred stock, or a specified portion
thereof, may be effected by delivering certificates evidencing such shares,
together with written notice of conversion and a proper assignment of such
certificates to McLeodUSA or in blank, to the office or agency to be maintained
by McLeodUSA for that purpose. Initially, Norwest Shareowner Services will
maintain such office.

  Each conversion will be deemed to have been effected immediately prior to the
close of business on the date on which the certificates for shares of Series A
preferred stock shall have been surrendered and notice (and if applicable,
payment of an amount equal to the dividends payable on such shares) received by
McLeodUSA. McLeodUSA will issue a certificate evidencing the Class A common
stock distributed upon conversion as soon as reasonably practical after the
conversion date.

  All shares of Class A common stock distributed upon conversion will be freely
transferable without restriction under the Securities Act.

  Holders of shares of Series A preferred stock at the close of business on a
dividend payment record date will be entitled to receive the dividend payable
on such shares on the corresponding dividend payment date notwithstanding the
conversion of such shares following the dividend payment record date and prior
to such

                                      S-29
<PAGE>

dividend payment date. However, shares of Series A preferred stock surrendered
for conversion during the period between the close of business on any dividend
payment record date and the opening of business on the corresponding dividend
payment date (except shares converted after the issuance of a notice of
redemption with respect to a redemption date during such period, which will be
entitled to such dividend) must be accompanied by payment of an amount equal
to the dividend payable on such shares on such dividend payment date. A holder
of shares of Series A preferred stock on a dividend payment record date who
(or whose transferee) tenders any such shares for conversion into shares of
Class A common stock on such dividend payment date will receive the dividend
payable on such shares of Series A preferred stock on such date, and the
converting holder need not include payment of the amount of such dividend upon
surrender of shares of Series A preferred stock for conversion. Except as
provided above, we will make no payment or allowance for unpaid dividends,
whether or not in arrears, on converted shares or the dividends on the shares
of Class A common stock issued upon such conversion.

  Fractional shares of Class A common stock will not be issued upon conversion
but, in lieu thereof, we will pay a cash adjustment based on the current
market price (as defined) of the Class A common stock on the business day
prior to such conversion date.

The Conversion Price is subject to adjustment upon certain events, including:

  (1) any redemption payment or payment of a dividend or other distribution
      payable in shares of Class A common stock to all holders of any class
      of capital stock of McLeodUSA, other than the issuance of shares of
      Class A common stock in connection with the payment (1) in redemption
      for, of dividends on or upon the conversion of the Series A preferred
      stock or (2) to all holders of the Series A preferred stock based upon
      the number of shares of Class A common stock into which the Series A
      preferred stock is then convertible;

  (2) any issuance to all holders of shares of McLeodUSA's common stock of
      rights, options or warrants entitling them to subscribe for or purchase
      shares of Class A common stock or securities convertible into or
      exchangeable for shares of Class A common stock at less than market
      value as of the date of conversion or exchange; provided, however, that
      no adjustment will be made with respect to such a distribution if the
      holder of shares of the Series A preferred stock would be entitled to
      receive such rights, options or warrants upon conversion at any time of
      shares of the Series A preferred stock into Class A common stock and
      provided, further, that if such rights, options or warrants are only
      exercisable upon the occurrence of certain triggering events, then the
      Conversion Price will not be adjusted until such triggering events
      occur;

  (3) any subdivision, combination or reclassification of Class A common
      stock;

  (4) any distribution consisting exclusively of cash or any other
      transaction for which the penultimate paragraph below is applicable,
      which specifies that no antidilution adjustment shall be made to all
      holders of shares of Class A common stock in an aggregate amount that,
      together with (1) all other such cash distributions made within the
      then preceding 12 months in respect of which no adjustment has been
      made and (2) any cash and the fair market value of other consideration
      paid or payable in respect of any tender offer by McLeodUSA or any of
      its subsidiaries for shares of Class A common stock concluded within
      the then preceding 12 months in respect of which no adjustment has been
      made, exceeds 15% of McLeodUSA's market capitalization (defined as the
      product of the then current market price of the Class A common stock
      times the number of shares of Class A common stock then outstanding on
      the record date of such distribution);

  (5) the completion of a tender or exchange offer which McLeodUSA or any of
      its subsidiaries makes for shares of Class A common stock that involves
      an aggregate consideration that, together with (1) any cash and other
      consideration payable in a tender or exchange offer by McLeodUSA or any
      of its subsidiaries for shares of any of the Class A common stock
      expiring within the then preceding 12 months in respect of which no
      adjustment has been made and (2) the aggregate amount of any such

                                     S-30
<PAGE>

     cash distributions referred to in clause 4 above to all holders of
     shares of Class A common stock within the then preceding 12 months in
     respect of which no adjustments have been made, exceeds 15% of
     McLeodUSA's market capitalization immediately prior to the expiration of
     such tender offer; or

  (6) a distribution to all holders of Class A common stock consisting of
      evidences of indebtedness, shares of capital stock other than Class A
      common stock or assets, including securities, but excluding those
      dividends and those issuances of rights, options, warrants and other
      distributions for which an adjustment to the Conversion Price as
      referred to above is applicable (other than in connection with a merger
      effected solely to reflect a change in the jurisdiction of
      incorporation of McLeodUSA).

  No adjustment of the Conversion Price will be required to be made:

      (A) until cumulative adjustments amount to one percent of such price,
  or

      (B) with respect to rights, options or warrants issued pursuant to
  certain employee benefit plans of McLeodUSA.

  McLeodUSA also may from time to time decrease the Conversion Price by any
amount for any period of at least 20 days, so long as the decrease is
irrevocable during such period, in which case McLeodUSA shall give at least 15
days' notice of such decrease. In addition to the foregoing adjustments,
McLeodUSA will be permitted to make such reductions in the Conversion Price as
it determines to be advisable in order that any stock dividend, subdivision of
shares, distribution of rights to purchase stock or securities or distribution
of securities convertible into or exchangeable for stock made by McLeodUSA to
its stockholders will not be taxable to the recipients. In the event McLeodUSA
elects to make such a reduction in the Conversion Price, McLeodUSA will comply
with the requirements of Rule 14e-1 under the Securities Exchange Act, and any
other securities laws and regulations thereunder, if and to the extent that
such laws and regulations are applicable in connection with the reduction of
the Conversion Price. See "Federal Tax Considerations."

  In the event that, after the issuance of the Series A preferred stock,
McLeodUSA distributes rights, options or warrants (other than those referred
to in clause B above) to all holders of Class A common stock, so long as any
such rights, options or warrants have not expired or been redeemed by
McLeodUSA, the holder of any shares of Series A preferred stock surrendered
for conversion will be entitled to receive upon such conversion, in addition
to the shares of Class A common stock then issuable upon such conversion,
which we call the conversion shares, a number of rights, options or warrants
to be determined as follows: (1) if such conversion occurs on or prior to the
date for the distribution to the holders of rights, options or warrants or
separate certificates evidencing such rights, options or warrants, called the
distribution date, the same number of rights, options or warrants to which a
holder of a number of shares of Class A common stock equal to the number of
conversion shares is entitled at the time of such conversion in accordance
with the terms and provisions applicable to the rights, options or warrants,
and (2) if such conversion occurs after such distribution date, the same
number of rights, options or warrants to which a holder of the number of
shares of Class A common stock into which such Series A preferred stock was
convertible immediately prior to such distribution date would have been
entitled on such distribution date in accordance with the terms and provisions
of and applicable to the rights, options or warrants.

  Except as stated above, the Conversion Price will not be adjusted for the
issuance of common stock, or any securities convertible into or exchangeable
for common stock or carrying the right to purchase any of the foregoing, in
exchange for cash, property or services.

  In case of:

      (1) any merger or consolidation of McLeodUSA, other than a merger or
  consolidation in which (a) McLeodUSA is the continuing corporation and (b)
  the Class A common stock outstanding immediately prior to the merger or
  consolidation is not exchanged for cash, securities or other property of
  another corporation;


                                     S-31
<PAGE>

     (2) any sale or transfer to another corporation of the property of
  McLeodUSA as an entirety or substantially as an entirety; or

     (3) any statutory exchange of securities with another corporation, other
  than in connection with a merger or acquisition,

there will be no adjustment of the Conversion Price. Each share of the then
outstanding Series A preferred stock will, without the consent of the holder of
any Series A preferred stock, become convertible only into the kind and amount
of securities, cash or other property receivable upon such merger,
consolidation, sale, transfer or statutory exchange by a holder of the number
of shares of Class A common stock into which such Series A preferred stock was
convertible immediately prior to such merger, consolidation, sale, transfer or
statutory exchange, assuming such holder of Class A common stock failed to
exercise his rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such merger, consolidation,
sale, transfer or statutory exchange. In the case of a cash merger of McLeodUSA
into another company or any other cash transaction of the type mentioned above,
the effect of these provisions would be that thereafter each share of Series A
preferred stock would be convertible at the Conversion Price in effect at such
time into the same amount of cash per share into which each share of Series A
preferred stock would have been convertible had such share been converted into
Class A common stock immediately prior to the effective date of such cash
merger or transaction. Depending upon the terms of such cash merger or
transaction, the aggregate amount of cash into which such shares of Series A
preferred stock would be converted could be more or less than the liquidation
preference with respect to such Series A preferred stock.

  Holders of Series A preferred stock at the close of business on a record date
will be entitled to receive the dividend payable on such shares on the
corresponding dividend payment date notwithstanding the conversion of such
shares following such record date and prior to such dividend payment date.
However, Series A preferred stock surrendered for conversion during the period
between the close of business on any record date and the opening of business on
the corresponding dividend payment date, except shares converted after the
issuance of a notice of redemption with respect to a redemption date during
such period or coinciding with such dividend payment date, which will be
entitled to such dividend, must be accompanied by payment of an amount equal to
the dividend payable on such shares on such dividend payment date. A holder of
Series A preferred stock on a record date who, or whose transferee, tenders any
such shares for conversion into shares of Class A common stock on such dividend
payment date will receive the dividend payable by McLeodUSA on such shares of
Series A preferred stock on such date. The converting holder need not include
payment of the amount of such dividend upon surrender of Series A preferred
stock for conversion. Except as provided above, McLeodUSA will make no payment
or allowance for unpaid dividends, whether or not in arrears, on converted
shares or for dividends on the Class A common stock issued upon such
conversion.

Change of Control


  Notwithstanding any other provision in the preceding paragraphs to the
contrary, if any Change in Control (as defined) occurs, then the Conversion
Price in effect will be adjusted immediately after such Change in Control as
described below. In addition, in the event of a Common Stock Change in Control
(as defined), each share of the Series A preferred stock shall be convertible
solely into common stock of the kind received by holders of Class A common
stock as the result of such Common Stock Change in Control.

  A "Change in Control" shall be deemed to have occurred at such time as:

 .      the sale, lease, transfer, conveyance or other disposition (other than
       by way of merger or consolidation), in one or a series of related
       transactions, of all or substantially all the assets of McLeodUSA to any
       "person" (as such term is used in Section 13(d)(3) of the Securities
       Exchange Act)

  .  the adoption of a plan relating to the liquidation, dissolution or
     winding-up of McLeodUSA

  .  the consummation of any transaction (including any merger or
     consolidation) the result of which is that any "person" (as defined
     above) other than any Permitted Holder (as defined below) becomes the
     beneficial owner (as such term is defined in Rules 13d-3 and 13d-5
     promulgated under the Securities Exchange Act, except that a person will
     be deemed to have beneficial ownership of all shares that such

                                      S-32
<PAGE>

     person has the right to acquire whether such right is exercisable
     immediately or only after the passage of time), directly or indirectly,
     of more than 50% of the voting stock of McLeodUSA, or

  .  the first day on which a majority of the members of the board of
     directors of McLeodUSA are not Continuing Directors (as defined in the
     Certificate of Designations)

"Permitted Holders" include: IES Industries Inc. and its successors and
assigns; Clark E. McLeod, Mary E. McLeod and Richard A. Lumpkin, and
foundations and trusts controlled by any of them; and affiliates (other than
the Company and its subsidiaries) of each of the foregoing.

  The term "Common Stock Change in Control" means any Change in Control in
which more than 50% of the value (as determined in good faith by McLeodUSA's
board of directors) or the consideration received by holders of Class A common
stock consists of common stock of another company that for each of the 10
consecutive Trading Days referred to in the definition of "Applicable Price"
below has been admitted for listing or admitted for listing subject to notice
of issuance on a national securities exchange or quoted on the Nasdaq National
Market; provided, however, that a Change in Control shall not be a Common
Stock Change in Control unless either (1) McLeodUSA continues to exist after
the occurrence of such Change in Control and the outstanding shares of Series
A preferred stock continue to exist as outstanding shares of Series A
preferred stock, or (2) not later than the occurrence of such Change in
Control, the outstanding shares of Series A preferred stock are converted into
or exchanged for shares of convertible preferred stock of a corporation
succeeding to McLeodUSA's business, which convertible preferred stock has
powers, preferences and relative, participating, optional or other rights, and
qualifications, limitations and restrictions, substantially similar to those
of the Series A preferred stock.

  The term "Non-Stock Change in Control" means any Change in Control other
than a Common Stock Change in Control.

  The term "Applicable Price" means (i) in the event of a Non-Stock Change in
Control in which the holders of the Class A common stock receive only cash,
the amount of cash received by the holder of one share of Class A common stock
and (ii) in the event of any other Non-Stock Change in Control or any Common
Stock Change in Control, the average of the closing prices for the Class A
common stock during the 10 Trading Days prior to and including the record date
for the determination of the holders of Class A common stock entitled to
receive cash, securities, property or other assets in connection with such
Non-Stock Change in Control or Common Stock Change in Control or, if there is
no such cash, securities, property or other assets or the date upon which such
Non-Stock Change in Control is deemed to have occurred, as the case may be, in
each case as adjusted in good faith by the board of directors to appropriately
reflect any of the events referred to in clauses 1 through 6 under "--
Conversion Rights."

  For purposes of calculating any adjustment to be made in the event of a
Change of Control, immediately after such Change in Control:

    (1) in the case of a Non-Stock Change in Control, the Conversion Price
  will thereupon become the lower of (A) the Conversion Price in effect
  immediately prior to such Non-Stock Change in Control, but after giving
  effect to any other prior adjustments, and (B) the results obtained by
  multiplying the greater of the Applicable Price and the then applicable
  Reference Market Price (as defined) by a fraction of which the numerator
  will be $1,000 and the denominator will be the then current redemption
  price per share or, prior to          , 2002, an amount per share of Series
  A preferred stock determined by McLeodUSA in its sole discretion, after
  consultation with an investment banking firm, to be the equivalent of the
  hypothetical redemption price that would have been applicable if the Series
  A preferred stock had been redeemable during such period; provided,
  however, that if, as a result of the operation of this clause (1), the
  cumulative number of shares of Class A common stock issued or issuable upon
  conversion of the Series A preferred stock, after giving effect to the
  adjustment described in this clause (1) and all prior conversions of Series
  A preferred stock, would exceed a number (the "Threshold Number") equal to
  20% of the outstanding shares of Class A common stock as of the issue date
  of the Series A preferred stock, then until and unless McLeodUSA obtains
  the approval of its common stockholders for the issuance

                                     S-33
<PAGE>

  of any shares of Class A common stock in excess of the Threshold Number,
  the Conversion Price shall be adjusted pursuant to this clause (1) to that
  price that would entitle the holders of Series A preferred stock to receive
  in the aggregate, upon conversion for all the Series A preferred stock
  (including all prior conversions of Series A preferred stock), no more than
  the Threshold Number of shares of Class A common stock; and

    (2) in the case of a Common Stock Change in Control, the Conversion Price
  in effect immediately prior to such Common Stock Change in Control, but
  after giving effect to any other prior adjustments, will thereupon be
  adjusted by multiplying such Conversion Price by a fraction, of which the
  numerator will be the Purchaser Stock Price (as defined) and the
  denominator will be the Applicable Price; provided, however, that in the
  event of a Common Stock Change in Control in which (A) 100% of the value of
  the consideration received by a holder of Class A common stock is common
  stock of the successor, acquiror or other third party (and cash, if any, is
  paid with respect to any fractional interests in such common stock
  resulting from such Common Stock Change in Control) and (B) all the Class A
  common stock will have been exchanged for, converted into, or acquired for,
  common stock (and cash with respect to fractional interests) of the
  successor, acquiror or other third party, the Conversion Price in effect
  immediately prior to such Common Stock Change in Control will thereupon be
  adjusted by multiplying such Conversion Price by a fraction, of which the
  numerator will be one (1) and the denominator will be the number of shares
  of common stock of the successor, acquiror, or other third party received
  by a holder of one share of our Class A common stock as a result of such
  Common Stock Change in Control.

  The foregoing Conversion Price adjustments in the event of a Non-Stock Change
in Control will apply in situations whereby a Change in Control not involving a
change in beneficial ownership of the Class A common stock has occurred or
whereby all or substantially all of the Class A common stock is acquired in a
transaction in which 50% or less of the value received by holders of such Class
A common stock consists of common stock that has been admitted for listing on a
national securities exchange or quoted on the Nasdaq National Market. If the
market price of the Class A common stock immediately prior to a Non-Stock
Change in Control is lower than the applicable Conversion Price then in effect,
the Conversion Price will be adjusted as described in clause 1 above and the
holders of the Series A preferred stock will be entitled to receive the amount
and kind of consideration that would have been received if the Series A
preferred stock had been converted into Class A common stock prior to the Non-
Stock Change in Control after giving effect to such adjustment.

  The foregoing Conversion Price adjustments in the event of a Common Stock
Change in Control will apply in situations whereby more than 50% of the value
received by holders of Class A common stock consists of common stock of another
company that has been admitted for listing on a national securities exchange or
quoted on the Nasdaq National Market, in which case the Series A preferred
stock will become convertible into shares of common stock of the other company.
If consideration for the Class A common stock consists partly of common stock
of another company and partly of other securities, cash or property, each share
of Series A preferred stock will be convertible solely into a number of shares
of such common stock determined so that the initial value of such shares
(measured as described in the definition of Purchaser Stock Price) equals the
value of the shares of Class A common stock into which such share of Series A
preferred stock was convertible immediately before the transaction (measured as
described in the definition of Applicable Price). If consideration for Class A
common stock is solely common stock of another company, each share of Series A
preferred stock will be convertible into the same number of shares of such
common stock of another company receivable by a holder of the number of shares
of Class A common stock into which such share of Series A preferred stock was
convertible immediately before such transaction.

  The term "Purchaser Stock Price" means, with respect to any Common Stock
Change in Control, the product of (1) the number of shares of common stock
received as consideration in such Common Stock Change in Control for each share
of Class A common stock, and (2) the average of the per share closing prices
for the common stock received as consideration in such Common Stock Change in
Control for the 10 consecutive

                                      S-34
<PAGE>

Trading Days prior to and including the record date for the determination of
the holders of Class A common stock entitled to receive such common stock, or,
if there is no such record date, the date upon which the holders of the Class A
common stock shall have the right to receive such common stock, in each case,
as adjusted in good faith by the board of directors of McLeodUSA to
appropriately reflect any of the events referred to in clauses 1 through 6
under "--Conversion Rights"; provided, however, that if no such closing prices
exist, then the Purchaser Stock Price shall be set at a price determined in
good faith by the board of directors of McLeodUSA.


  The term "Reference Market Price" shall initially mean $        (which is an
amount equal to 66 2/3% of the reported last sale price for the Class A common
stock on the Nasdaq National Market on          , 1999), and in the event of
any adjustment to the Conversion Price other than as a result of a Change in
Control, the Reference Market Price shall also be adjusted so that the ratio of
the Reference Market Price to the Conversion Price after giving effect to any
such adjustment shall always be the same as the ratio of $        to the
initial Conversion Price set forth on the cover page of this prospectus
supplement.

  Depending upon whether a Change in Control is a Non-Stock Change in Control
or Common Stock Change in Control, a holder of Series A preferred stock may
receive significantly different consideration upon conversion. In the event of
a Non-Stock Change in Control, the holder has the right to convert each share
of the Series A preferred stock into the kind and amount of the shares of stock
and other securities or property or assets receivable by a holder of the number
of shares of Class A common stock issuable upon conversion of such share of the
Series A preferred stock immediately prior to such Non-Stock Change in Control,
but after giving effect to the adjustment described above. However, in the
event of a Common Stock Change in Control in which less than 100% of the value
of the consideration received by a holder of Class A common stock is common
stock of the acquiror or other third party, a holder of a share of Series A
preferred stock who converts a share following the Common Stock Change in
Control will receive consideration in the form of such common stock only,
whereas a holder who has converted his share prior to the Common Stock Change
in Control will receive consideration in the form of common stock as well as
any other securities or assets (which may include cash) receivable thereupon by
a holder of the number of shares of Class A common stock issuable upon
conversion of such share of Series A preferred stock immediately prior to such
Common Stock Change in Control.

  In the case of certain reclassifications, consolidations, mergers, sales or
transfers of assets or other transactions pursuant to which the Class A common
stock is converted into the right to receive other securities, cash or other
property, each share of Series A preferred stock then outstanding would,
without the consent of any holders of Series A preferred stock, become
convertible only into the kind and amount of securities, cash and other
property receivable upon the transaction by a holder immediately prior to such
transaction if such holder had converted its share of Series A preferred stock.

  If at any such time McLeodUSA makes a distribution of property to its
stockholders that would be taxable to such stockholders as a dividend for
federal income tax purposes (for example, distributions of evidences of
indebtedness or assets of McLeodUSA, but generally not stock dividends or
rights to subscribe for capital stock) and, pursuant to the antidilution
provisions described above, the Conversion Price of the Series A preferred
stock is reduced, such reduction may be deemed to be the receipt of taxable
income by holders of the Series A preferred stock.

Consolidation, Merger and Sale of Assets

  The Certificate of Designations will provide that McLeodUSA, without the
consent of the holders of any of the outstanding Series A preferred stock, may
consolidate with or merge into any other Person or convey, transfer or lease
its properties and assets substantially as an entirety to any Person or may
permit any Person to consolidate with or merge into, or transfer or lease its
properties substantially as an entirety to, McLeodUSA
provided, however that (a) the successor, transferee or lessee is organized
under the laws of the United States,

                                      S-35
<PAGE>

any state thereof or the District of Columbia, (b) the shares of Series A
preferred stock shall become shares of such successor, transferee or lessee,
having in respect of such successor, transferee or lessee the same powers,
preferences and relative, participating, optional or other special rights and
the qualifications, limitations or restrictions thereon, the Series A preferred
stock had immediately prior to such transaction; and (c) certain other
conditions are met.

  Under any consolidation by McLeodUSA with, or merger by McLeodUSA into, any
other Person or any conveyance, transfer or lease of the properties and assets
of McLeodUSA substantially as an entirety as described in the preceding
paragraph, the successor resulting from such consolidation or into which
McLeodUSA is merged or the transferee or lessee to which such conveyance,
transfer or lease is made, will succeed to, and be substituted for, and may
exercise every right and power of, McLeodUSA under the shares of Series A
preferred stock, and thereafter, except in the case of a lease, the predecessor
(if still in existence) will be released from its obligations and covenants
with respect to the Series A preferred stock.

SEC Reports and Reports to Holders

  Whether or not we are required to file reports with the SEC, if any shares of
Series A preferred stock are outstanding, we will file with the SEC all such
reports and other information as we would be required to file with the SEC by
Sections 13(a) or 15(d) under the Securities Exchange Act. See "Where You Can
Find More Information." We will supply each holder of Series A preferred stock,
upon request, without cost to such holder, copies of such reports or other
information.

Transfer Agent, Registrar and Dividend Disbursing Agent

  The transfer agent, registrar, dividend disbursing agent and redemption agent
for the shares of Series A preferred stock will be Norwest Bank Minnesota, N.A.

                          FEDERAL TAX CONSIDERATIONS

  The following is a summary of certain material U.S. federal tax
considerations relevant to the purchase, ownership and disposition of our
Series A preferred stock and Class A common stock. This summary is based on
the current provisions of the Internal Revenue Code of 1986, as amended,
Treasury regulations and judicial and administrative authority, all of which
are subject to change, possibly on a retroactive basis. This summary applies
only to investors who hold our Series A preferred stock or Class A common
stock as capital assets, within the meaning of section 1221 of the Internal
Revenue Code, and does not discuss the tax consequences to special classes of
investors, such as brokers or dealers in securities or currencies, financial
institutions, tax-exempt entities, life insurance companies, persons holding
our convertible preferred stock or common stock as a part of a hedging, short
sale or conversion transaction or a straddle, investors whose functional
currency is not the United States dollar, persons who hold our convertible
preferred stock or common stock through partnerships or other pass-through
entities, or, except as specifically noted, foreign holders and certain U.S.
expatriates. State, local and foreign tax consequences of ownership of our
Series A preferred stock and Class A common stock are not summarized.

  We have not requested, and do not intend to request, any rulings from the
Internal Revenue Service concerning the federal tax consequences of an
investment in our Series A preferred stock or Class A common stock. You are
advised to consult with your own tax advisor regarding the consequences of
acquiring, holding or disposing of our Series A preferred stock or Class A
common stock in light of current tax laws, your particular investment
circumstances, and the application of state, local and foreign tax laws.

  When we refer in the summary to a "United States Holder," we mean a
beneficial owner of Series A preferred stock or Class A common stock that is:

  .  a citizen or resident of the United States for United States federal
     income tax purposes

  .  a corporation created or organized in the United States or under the
     laws of the United States or of any political subdivision thereof

  .  an estate whose income is includible in gross income for United States
     federal income tax purposes regardless of its source, or

  .  a trust if a court within the United States is able to exercise primary
     supervision of the administration of the trust and one or more United
     States persons has the authority to control all substantial decisions of
     the trust

  When we refer in the summary to a "Non-United States Holder," we mean a
beneficial owner of convertible preferred stock or common stock that is not a
United States Holder.

United States Holders

 Distributions

  We have the right to pay distributions on the Series A preferred stock and
the Class A common stock in cash or in shares of our Class A common stock. If
we distribute our Class A common stock, the amount of the distribution for
federal income tax purposes will be the fair market value (which may differ
from the Discounted Current Market Value) of the Class A common stock on the
date the distribution is paid, and the distribution will be subject to federal
income tax to the same extent as a cash distribution.

  A distribution on the Series A preferred stock or Class A common stock will
be treated as a dividend to the extent of our current or accumulated earnings
and profits attributable to the distribution as determined under U.S. federal
income tax principles. The amount of our earnings and profits at any time will
depend upon our future actions and financial performance. If the amount of the
distribution exceeds our current and accumulated earnings and profits
attributable to the distribution, the distribution will be treated as a
nontaxable return of capital and will be applied against and reduce your
adjusted tax basis in the stock, but not below zero. The

                                     S-37
<PAGE>

reduction in tax basis will increase the amount of any gain, or reduce the
amount of any loss, which you would otherwise realize on the sale or other
taxable disposition of the stock. If the distribution exceeds both our current
and accumulated earnings and profits attributable to the distribution and your
adjusted tax basis in your stock, the excess will be treated as capital gain
and will be either long-term or short-term capital gain depending on your
holding period for the stock.

  Corporate investors in our Series A preferred stock or Class A common stock
generally should be eligible for the 70% dividends-received deduction with
respect to the portion of any distribution on the stock taxable as a dividend.
However, corporate investors should consider certain provisions that may limit
the availability of a dividend received deduction, including the 46-day holding
period required by section 246(c) of the Internal Revenue Code, the rules of
section 246A which reduce the dividends-received deduction of dividends on
certain debt-financed stock, and the rules in section 1059 of the Internal
Revenue Code that reduce the basis of stock in respect of certain extraordinary
dividends, as well as the effect of the dividends-received deduction on the
determination of alternative minimum tax liability.

 Optional redemption for Class A common stock or cash

  If we redeem our Series A preferred stock for Class A common stock, the
exchange should constitute a recapitalization within the meaning of Section
368(a)(1)(E) of the Internal Revenue Code. You will not recognize gain or loss
on the exchange unless some of the Class A common stock is received in
discharge of dividend arrearages, in which case the redemption will be treated
as a distribution on the Series A preferred stock to the extent of the
dividends in arrears. The amount constituting a distribution will be taxed as a
dividend to the extent of our current or accumulated earnings and profits
attributable to the distribution at the time, in accordance with the treatment
described above for distributions. Your tax basis in our Class A common stock
received pursuant to the redemption generally will equal your tax basis in the
Series A preferred stock surrendered in exchange, and your holding period for
the Class A common stock generally will include the period you held your Series
A preferred stock. However, the tax basis of Class A common stock received in
discharge of dividend arrearages will be its fair market value on the date
received and the holding period of that stock will commence on the day after
its receipt.

  If we redeem our Series A preferred stock for cash, the redemption will be
taxable to you. The redemption generally will be treated as a sale or exchange
if you do not own, actually or constructively within the meaning of section 318
of the Internal Revenue Code, any stock of McLeodUSA other than the redeemed
Series A preferred stock. If you do own, actually or constructively, other
stock of McLeodUSA, a cash redemption of your Series A preferred stock may be
taxable in accordance with the treatment described above for distributions.
Such treatment as a distribution will not apply if the redemption (1) is
"substantially disproportionate" with respect to you under section 302(b)(2) of
the Internal Revenue Code, or (2) is "not essentially equivalent to a dividend"
under section 302(b)(1) of the Internal Revenue Code. A distribution to you
will be "not essentially equivalent to a dividend" if results in a meaningful
reduction in your stock interest in us, which should be the case if your
proportionate ownership interest, taking into account any actual ownership of
Class A common stock and any stock constructively owned, is reduced, your
relative stock interest in McLeodUSA is minimal, and you exercise no control
over our business affairs.

  If a cash redemption of your Series A preferred stock is treated as a sale or
exchange, it will result in capital gains or losses equal to the difference
between the amount of cash received and the adjusted tax basis in the Series A
preferred stock redeemed, except to the extent that the redemption price
includes unpaid dividends which we declare prior to the redemption. The capital
gain or loss will be long term if you have held the Series A preferred stock
for more than one year. Any cash you receive in discharge of dividend
arrearages on the Series A preferred stock will be treated as a distribution on
the Series A preferred stock to the extent of the dividends in arrears, taxable
in accordance with the treatment described above for distributions.

  If the cash you receive on redemption of your Series A preferred is taxed as
a dividend, your tax basis (reduced for amounts, if any, treated as return of
capital) in the redeemed Series A preferred stock will be

                                      S-38
<PAGE>

transferred to any remaining other McLeodUSA stock you own, subject, in the
case of a corporate taxpayer, to reduction of possible gain recognition under
section 1059 of the Internal Revenue Code in an amount equal to the nontaxed
portion of such dividend. If you do not actually own any other McLeodUSA stock,
having a remaining stock interest only constructively, you may lose the benefit
of your tax basis in the Series A preferred stock but the tax basis may be
shifted to the stock of the related person whose stock you constructively own.

  Under certain circumstances, section 305(c) of the Internal Revenue Code
requires that any excess of the redemption price of preferred stock over its
issue price be treated as constructively distributed on a periodic basis prior
to actual receipt. However, these rules do not apply if you and McLeodUSA are
not "related" within the meaning of Treasury regulations under section 305(c),
there are no plans, arrangements or agreements that effectively require or are
intended to compel us to redeem the Series A preferred stock, and our exercise
of the right to redeem would not reduce the yield of the Series A preferred
stock, as determined under the regulations. We intend to take the position that
the existence of our optional redemption rights does not result in a
constructive distribution under section 305(c). The preferred stock will also
be issued with a liquidation premium, since the liquidation preference will
exceed the proceeds received by us after excluding amounts deposited in the
deposit account. Although the regulations under section 305(c) do not
specifically address the treatment of liquidation premiums, we believe that a
similar rationale should apply to such premiums.

 Conversion

  You generally will not recognize gain or loss on conversion of shares of
Series A preferred stock into our Class A common stock, except with respect to
any cash paid in lieu of fractional shares of Class A common stock. However,
you may recognize gain or dividend income to the extent there are dividends in
arrears on such stock at the time of conversion into Class A common stock. Your
tax basis in the common stock received upon conversion of Series A preferred
stock generally will be equal to your tax basis in the Series A preferred stock
and the holding period of the Series A common stock generally will include your
holding period for the Series A preferred stock. However, the tax basis of any
Class A common stock received on conversion which is treated as a dividend will
be equal to its fair market value on the date of the distribution and the
holding period of that Class A common stock will commence on the day after its
receipt.

  You may be deemed to have received a constructive distribution of stock
taxable as a dividend if the conversion ratio of the Series A preferred stock
is adjusted to reflect a cash or property distribution on our Class A common
stock or to prevent dilution in the case of certain issuances of rights or
warrants to purchase Class A common stock at below market prices. Although an
adjustment to the conversion price made pursuant to a bona fide reasonable
adjustment formula which has the effect of preventing the dilution your
interest in McLeodUSA generally will not be considered to result in a
constructive distribution of stock, certain of the possible adjustments may
trigger this rule. If a nonqualifying adjustment is made, or if we fail to make
an adjustment in certain cases, you might be deemed to have received a taxable
stock dividend. If so, the amount of the dividend to be included in income
would be the fair market value of the additional Class A common stock to which
you would be entitled by reason of the increase in your proportionate equity
interest in McLeodUSA.

 Sale or other taxable disposition

  If you sell or dispose of your Series A preferred stock or Class A common
stock in a taxable transaction other than a redemption or conversion by us, you
will recognize capital gain or loss equal to the difference between the amount
of cash and the fair market value of property received and your tax basis in
the Series A preferred stock or Class A common stock. The gain or loss will be
long-term capital gain or loss if your holding period for the stock exceeds one
year. For corporate taxpayers, long-term capital gains are taxed at the same
rate as ordinary income. For individual taxpayers, net capital gains--the
excess of the taxpayer's net long-term capital gains over this net short-term
capital losses--are subject to a maximum tax rate of 20% if the stock is held
for more than one year.

Non-United States Holders

 Distributions

  Distributions received by you as a Non-United States Holder in respect of
the Series A preferred stock, whether in cash or shares of Class A common
stock, and distributions in respect of Class A common stock, to the extent
considered dividends for U.S. federal income tax purposes, generally will be
subject to withholding of United States federal income tax at a 30% rate or
such lower rate as may be specified by an applicable income tax treaty, unless
the dividend is effectively connected with your conduct of a trade or business
within the United States or, where a tax treaty applies, is attributable to a
United States permanent establishment you maintain. For distributions of Class
A common stock, any amounts we withhold will reduce the value of the Class A
common stock distributed to you. If the dividend is effectively connected with
your conduct of a trade or business within the United States or, where a tax
treaty applies, is attributable to your United States permanent establishment,
the dividend will be subject to federal income tax on a net income basis at
applicable graduated individual or corporate rates and will be exempt from the
30% withholding tax.

  In addition to the graduated rate described above, dividends received by a
corporate Non-United States Holder that are effectively connected with a
United States trade or business or, where a tax treaty applies, is
attributable to your United States permanent establishment, may, under certain
circumstances, be subject to an additional "branch profits tax" at a 30% rate
or at a lower rate specified by an applicable income tax treaty.

  For purposes of obtaining a reduced rate of withholding under an income tax
treaty, you will be required to provide certain information concerning your
country of residence and entitlement to tax treaty benefits.
If you claim exemption from withholding with respect to dividends effectively
connected with your conduct of a business within the United States, you must
provide appropriate certification, currently, Internal Revenue Service Form
4224, to McLeodUSA or its paying agent. If you are eligible for a reduced rate
of U.S. federal withholding tax you may obtain a refund of any excess withheld
amounts by timely filing an appropriate claim for refund.

  If a distribution exceeds our current and accumulated earnings and profits
attributable to the distribution, it will be treated first as a return of your
tax basis in the stock to the extent of your basis and then as gain from the
sale of a capital asset which would be taxable as described below. Any
withholding tax on distributions in excess of our current and accumulated
earnings and profits is refundable to you upon the timely filing of an
appropriate claim for refund with the Internal Revenue Service.

  Under currently applicable Treasury regulations, dividends paid to an
address outside the United States are presumed to be paid to a resident of
such country, unless the payor has knowledge to the contrary, for purposes of
the withholding discussed above, and, under the current interpretation of
these Treasury regulations, for purposes of determining the applicability of a
tax treaty rate. Under Treasury regulations currently scheduled to be
effective with respect to dividends paid after December 31, 2000, a Non-United
States Holder of McLeodUSA stock who wishes to claim the benefit of an
applicable treaty rate, and to avoid backup withholding as discussed below,
will be required to satisfy applicable certification and other requirements.
However, under either set of regulations, some payments to foreign partnership
and fiscally transparent entities may not be eligible for a reduced rate of
withholding tax under an applicable income tax treaty.

 Disposition of Series A preferred stock or Class A common stock

  Generally, you will not be subject to United States federal income tax on
any gain recognized upon the sale or other disposition of Series A preferred
stock or Class A common stock. However, you will be subject to federal income
tax on the gain if:

    (1) the gain is effectively connected with your United States trade or,
   if a tax treaty applies, attributable to your United States permanent
   establishment;

    (2) you are an individual who is a former citizen of the United States
   who lost such citizenship within the preceding ten-year period, or former
   long-term resident of the United States who relinquished United States
   residency on or after February 6, 1995, and the loss of citizenship or
   permanent residency had as one of its principal purposes the avoidance of
   United States tax; or

                                     S-40
<PAGE>

    (3) you are a non-resident alien individual, are present in the United
  States for 183 days or more days in the taxable year of disposition and
  either (a) have a "tax home" in the United States for United States federal
  income tax purposes or (b) the gain is attributable to an office or other
  fixed place of business you maintain in the United States.

  You will also be subject to federal income tax on the gain from the sale of
our Series A preferred stock or Class A common stock if we are or have been a
"United States real property holding corporation"--which we refer to in this
prospectus supplement as USRPHC--within the meaning of section 897(c)(2) of
the Internal Revenue Code at any time you held the stock, or within the five-
year period preceding the sale of the stock if you hold the stock for more
than five years. We believe we are not now a USRPHC, that we have not been an
USRPHC at any time since we were formed, and that it is unlikely we will
become a USRPHC. If we were a USRPHC or were to become a USRPHC, you would be
subject to U.S. income tax on any gain from your sale of Series A preferred
stock or from your sale of Class A common stock if you beneficially own, or
owned at any time during a specified 5-year period, more than 5 percent of the
total fair market value of the class of stock you sold.

 Redemption and conversion of Series A preferred stock

  As a Non-United States Holder, you generally will not recognize any gain or
loss for United States federal income tax purposes upon conversion of Series A
preferred stock into Class A common stock, except with respect to any cash
paid in lieu of fractional shares of Class A common stock, which would be
subject to the rules described under "Disposition of Series A preferred stock
or Class A common stock." However, you may recognize gain or dividend income
to the extent there are dividends in arrears on the Series A preferred stock
at the time of conversion into Class A common stock.

  A redemption of Series A preferred stock for cash will be an event which
will constitute either a dividend to the extent of our current and accumulated
earnings and profits or a sale or exchange. See "United States Holders--
Optional redemption for Class A common stock or cash." To the extent the
redemption is treated as a dividend, the tax consequences are described in
"Non-United States Holders--Distributions," and to the extent the redemption
is treated as a sale or exchange, the tax consequences are described in "Non-
United States Holders--Disposition of Series A preferred stock or Class A
common stock."

 Federal estate taxes

  If you are an individual Non-United States Holder, Series A preferred stock
or Class A common stock you hold or are treated as owning at the time of your
death will be included in your United States gross estate for United States
federal estate tax purposes and may be subject to United States federal estate
tax, unless an applicable estate tax treaty provides otherwise.

Information Reporting And Backup Withholding

  We generally will be required to report to certain holders of our Series A
preferred stock or Class A common stock and to the Internal Revenue Service
the amount of any dividends paid to the holder in each calendar year and the
amounts of tax withheld, if any, with respect to such payments. Copies of the
information returns reporting such dividends and withholding may also be made
available to the tax authorities in the country in which a Non-United States
Holder resides under the provisions of an applicable income tax treaty.

  Each holder of Series A preferred stock or Class A common stock--other than
an exempt holder such as a corporation, tax-exempt organization, qualified
pension or profit-sharing trust, individual retirement account, or a
nonresident alien individual who provides certification as to his or her
status as a nonresident--will be required to provide, under penalties of
perjury, a certification setting forth the holder's name, address, correct
federal taxpayer identification number and a statement that the holder is not
subject to backup withholding. If a nonexempt holder fails to provide the
required certification, we will be required to withhold 31% of the amount
otherwise payable to the holder, and remit the withheld amount to the Internal
Revenue Service as a credit

                                     S-41
<PAGE>

against the holder's federal income tax liability. However, no backup
withholding will be required with respect to any payment subject to the 30%
United States withholding tax discussed above. You should consult your own tax
advisor regarding your qualification for exemption from backup withholding and
the procedure for obtaining any applicable exemption.

  The Internal Revenue Service has finalized Treasury regulations regarding the
backup withholding and information rules which are effective for payments made
after December 31, 2000 subject to certain transition rules. In general, these
regulations unify certification procedures and forms and clarify and modify
reliance standards. Among other provisions, these regulations also include the
new provisions discussed below regarding sales of stock outside the United
States by or for a broker. A Non-United States Holder should consult its own
tax advisor regarding the application of the new regulations.

  Payment of the proceeds of a sale of Series A preferred stock or Class A
common stock by or through a United States office of a broker is subject to
both backup withholding and information reporting unless the beneficial owner
certifies under penalties of perjury that it is a Non-United States Holder or
otherwise establishes an exemption. In general, backup withholding and
information reporting will not apply to a payment of the proceeds of a sale of
Series A preferred stock or Class A common stock by or through a foreign office
of a broker. If, however, such broker is, for United States federal income tax
purposes a United States person, a "controlled foreign corporation" for U.S.
federal tax purposes, or a foreign person that derives 50% or more of its gross
income for a certain period from the conduct of a trade or business in the
United States, or, for taxable years beginning after December 31, 2000, a
foreign partnership in which one or more United States persons, in the
aggregate, own more than 50% of the income or capital interests in the
partnership or if the partnership is engaged in a trade or business in the
United States, such payments will be subject to information reporting, but not
backup withholding, unless (1) such broker has documentary evidence in its
records that the beneficial owner is a Non-United States Holder and certain
other conditions are met, or (2) the beneficial owner otherwise establishes an
exemption.

  For payments after December 31, 2000, certification will be required in the
case of the disposition of shares of Series A preferred stock or Class A common
stock held in an offshore account if the disposition is made through a foreign
broker described in the immediately preceeding paragraph.

  Any amounts withheld under the backup withholding rules may be allowed as a
refund or a credit against the holder's United States federal income tax
liability provided the required information is furnished to the Internal
Revenue Service.

  The foregoing discussion is for general information and is not tax advice.
Accordingly, each prospective holder of Series A preferred stock or Class A
common stock should consult its tax advisor as to the particular tax
consequences to it of the Series A preferred stock and Class A common stock,
including the applicability and effect of any state, local or foreign income
tax laws, and any recent or prospective changes in applicable tax laws.

</TABLE>

  In the underwriting agreement, the underwriters have severally agreed,
subject to the terms and conditions set forth therein, to purchase all of the
shares of Series A preferred stock offered hereby (other than those subject to
the over-allotment option described below), if any such shares are purchased.
In the event of a default by any underwriter, the underwriting agreement
provides that, in certain circumstances, the purchase commitments of the non-
defaulting underwriters may be increased or the underwriting agreement may be
terminated.

  The underwriters, for whom Salomon Smith Barney Inc., Goldman, Sachs & Co.
and Morgan Stanley Dean Witter are acting as representatives, propose initially
to offer the shares of Series A preferred stock to the public at the public
offering price set forth on the cover page of this prospectus supplement, and
to some dealers at such price less a concession not in excess of $   per share.
The underwriters may allow, and such dealers may reallow, a concession not in
excess of $   per share to other dealers. After the public offering, the public
offering price and such concessions may be changed.

  We have granted the underwriters an option, exercisable within 30 days of the
date of this prospectus supplement, to purchase up to 60,000 additional shares
of Series A preferred stock to cover over-allotments, if any, at the public
offering price set forth on the cover page of this prospectus supplement. To
the extent that the underwriters exercise such option, in whole or in part,
each underwriter will have a firm commitment, subject to several conditions, to
purchase the same proportion of the option shares as the number of shares
purchased by such underwriter in the above table bears to the total number of
Series A preferred stock purchased by all of the underwriters in the table
above.

  The following table shows the per share and total public offering price, the
underwriting discount to be paid to the underwriters, and the proceeds before
expenses to us. The totals are presented assuming either no exercise or full
exercise by the underwriters of the over-allotment option.

  In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell the shares of Series A preferred stock
and/or shares of our Class A common stock in the open market. These
transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of our shares
of Series A preferred stock in excess of the number of shares of Series A
preferred stock to be purchased by the underwriters in the offering, which
creates a syndicate short position. Syndicate covering transactions involve
purchases of our shares of Series A preferred stock in the open market after
the distribution has been completed in order to cover syndicate short
positions. Stabilizing transactions consist of bids or purchases of our shares
of Series A preferred stock and/or shares of our Class A common stock made for
the purpose of preventing or retarding a decline in the market price of our
shares of Series A preferred stock and/or shares of our Class A common stock
while the offering is in progress.

                                      S-43
<PAGE>

  The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when the
underwriters, in covering syndicate short positions or making stabilizing
purchases, repurchase shares originally sold by that syndicate member.

  Any of these activities may cause the price of our shares of Series A
preferred stock and/or our Class A common stock to be higher than the price
that otherwise would exist in the open market in the absence of such
transactions. These transactions may be effected on the Nasdaq National Market
or in the over-the-counter market, or otherwise and, if commenced, may be
discontinued at any time.

  In addition, in connection with this offering, the underwriters (and selling
group members) may engage in passive market making transactions in our Class A
common stock on the Nasdaq National Market prior to the pricing and completion
of the offering. Passive market making consists of displaying bids on the
Nasdaq National Market no higher than the bid prices of independent market
makers and making purchases at no higher than those independent bids and
effected in response to order flow. Net purchases by a passive market maker on
each day are limited to a specified percentage of the passive market maker's
average daily trading volume in our Class A common stock during a specified
period and must be discontinued when such limit is reached. Passive market
making may cause the price of our Class A common stock to be higher than the
price that otherwise would exist in the open market in the absence of such
transactions. If passive market making is commenced, it may be discontinued at
any time.

  We estimate that the total expenses of this offering will be $     .

  Salomon Smith Barney Inc. and Morgan Stanley Dean Witter have performed
investment banking and advisory services for us from time to time for which
they have received customary fees and expenses. They may, from time to time,
engage in transactions with and perform services for us in the ordinary course
of their business.

  The underwriting agreement provides that we will indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act, or
contribute to payments the underwriters may be required to make in respect of
such liabilities.

  We, our directors and officers, and several other stockholders have each
agreed with the underwriters that they will not offer, sell or contract to
sell, or otherwise dispose of, directly or indirectly, or announce an offering
of any shares of our Class A common stock or any securities convertible into,
or exchangeable for, shares of Class A common stock for a period of   days from
the date of this prospectus supplement, without the prior written consent of
Salomon Smith Barney Inc., except:

  .  in the case of McLeodUSA, any such transactions in connection with
     acquisitions, employee benefit or option plans, or upon conversion of
     outstanding securities

  .  in the case of our directors, officers and stockholders, dispositions of
     shares of our Class A common stock as bona fide gifts or pledges where
     the recipients of such gifts or the pledgees, as the case may be, agree
     in writing with the underwriters to be bound by these same restrictions

In addition, Clark E. McLeod, Mary E. McLeod, Interstate Energy, M/C, and
Richard A. Lumpkin and Gail G. Lumpkin and several other parties related to the
Lumpkins have agreed not to sell or otherwise dispose of any of our equity
securities without the consent of the board of directors of McLeodUSA. See
"Description of Capital Stock--Stockholders' Agreement."

                                    SUMMARY

  The following summary highlights selected information about us. It does not
contain all of the information that is important to you. You should carefully
read this entire prospectus supplement and accompanying prospectus and the
other documents to which those documents refer you. In addition, you should
carefully consider the factors set forth under the caption "Risk Factors."
Unless otherwise indicated, dollar amounts over $1 million have been rounded
to one decimal place and dollar amounts less than $1 million have been rounded
to the nearest thousand.

                                  Our Company

We provide communications services to business and residential customers in
the Midwestern and Rocky Mountain regions of the United States. We offer
local, long distance, Internet access, data, voice mail and paging services,
from a single company on a single bill. We believe we are the first company in
many of our markets to offer one-stop shopping for communications services
tailored to customers' specific needs.

Our approach makes it easier for both our business and our residential
customers to satisfy their communications needs. It also allows businesses to
receive customized services, such as competitive long distance pricing and
enhanced calling features, that might not otherwise be directly available on a
cost-effective basis. As of March 31, 1999, we served over 494,700 local lines
in 408 cities and towns and have a combined total of 488 switches and central
office locations.

In addition to our core business of providing competitive local, long distance
and related communications services, we also derive revenue from:

 .  sale of advertising space in telephone directories

 .  traditional local telephone company services in east central Illinois and
   southeast South Dakota

 .  special access, private line and data services

 .  communications network maintenance services

 .  telephone equipment sales, leasing, service and installation

 .  video services

 .  telemarketing services

 .  computer networking services

 .  other communications services, including cellular, operator, payphone,
   mobile radio, paging services and Web site development and hosting

We plan to derive revenues from high-speed digital access and data services
using Digital Subscriber Line and other technologies.

In most of our markets, we compete with the existing local phone company by
leasing its lines and switches. In other markets, primarily in east central
Illinois and southeast South Dakota, we operate our own lines and switches. We
provide long distance services by using our own communications network
facilities and leasing capacity from long distance and local communications
providers. We are constructing fiber optic communications networks in Iowa,
Illinois, Wisconsin, Indiana, Missouri, Michigan, Minnesota, South Dakota,
North Dakota, Colorado and Wyoming to carry additional communications traffic
on our own network.

                                 Our Strategy

We want to be the leading and most admired provider of communications services
in our markets. To achieve this goal, we are:

 .  aggressively capturing customer share and generating revenue using leased
   communications network capacity

 .  concurrently building our own communications network

 .  migrating customers to our communications network to provide enhanced
   services and to reduce our operating costs

The principal elements of our business strategy are to:

Provide integrated communications services. We believe we can rapidly
penetrate our target markets and build customer loyalty by providing an
integrated product offering to business and residential customers.

                                      S-1
<PAGE>


Build customer share through branding. We believe we will create and strengthen
brand awareness in our target markets by branding our communications services
with the trade name McLeodUSA in combination with the distinctive black-and-
yellow motif of our telephone directories.

Provide outstanding customer service. Our customer service representatives are
available 24 hours a day, seven days a week, to answer customer calls. Our
customer-focused software and systems allow our representatives immediate
access to our customer and network data, enabling a rapid and effective
response to customer requests.

Emphasize small and medium sized businesses. We primarily target small and
medium sized businesses because we believe we can rapidly capture customer
share by providing face-to-face business sales and strong service support to
these customers.

Expand our fiber optic communications network. We are building a state-of-the-
art fiber optic communications network to deliver multiple services and reduce
operating costs.

Expand our intra-city fiber optic communications network. Within selected
cities, we plan to extend our network directly to our customers' locations.
This will allow us to provide expanded services and reduce the expense of
leasing communications facilities from the existing local telephone company.

Explore acquisitions and strategic alliances. We plan to pursue acquisitions,
joint ventures and strategic alliances that expand or complement our business.

Leverage proven management team. Our executive management team consists of
veteran telecommunications managers who successfully implemented similar
customer-focused telecommunications strategies in the past.

                                ----------------
As of June 30, 1999, based on our business plan, capital requirements and
growth projections as of that date, we estimated that we would require
approximately $1.4 billion through 2001 to fund our planned capital
expenditures and operating expenses. Our estimated aggregate capital
requirements include the projected cost of:

 .  building our fiber optic communications network, including intra-city fiber
   optic networks
 .  expanding operations in existing and new markets
 .  developing wireless services
 .  funding general corporate expenses
 .integrating acquisitions
 .  constructing, acquiring, developing or improving telecommunication assets

We expect to use the following to address our capital needs:
 .  approximately $    million in net proceeds from the sale of the notes and
   the Series A preferred stock
 .  approximately $475.0 million of cash and investments on hand at June 30,
   1999
 .  projected operating cash flow
 .  additional issuances of debt or equity securities

Our estimate of future capital requirements is a forward-looking statement
within the meaning of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. The actual amount and timing of our future
capital requirements is subject to risks and uncertainties and may differ
materially from our estimates. Accordingly, we may need additional capital to
continue to expand our markets, operations, facilities, network and services.
See "Risk Factors--Failure to Raise Necessary Capital Could Restrict Our
Ability to Develop Our Network and Services and Engage in Strategic
Acquisitions."

                              Recent Developments

                  Acquisition of Ovation Communications, Inc.

  On March 31, 1999, we acquired Ovation Communications, Inc. for an aggregate
of 11,193,234 shares of our Class A common stock, after giving effect to the
two-for-one stock split described below, and $121.3 million in cash. We paid
approximately $105.6 million of the outstanding debt of Ovation at the time of
the transaction.

  Ovation is a diversified communications services company serving business
customers primarily in larger metropolitan areas in Minnesota, Illinois and
Wisconsin (such as Minneapolis/St. Paul, Chicago and Milwaukee) and in small to
mid-sized cities in Michigan. Ovation provides the following services:

  . local and network access

  . local and long distance telephone

  . voice mail, teleconferencing and calling card

  . Internet access

                         Announcement of Data Strategy

  On April 14, 1999, we announced plans to offer high-speed digital access and
data services as part of our integrated communications product package using
DSL (Digital Subscriber Line) and other technologies. These services are
expected to include:

  . basic dial tone transmitted digitally

  . high-speed data communications for Internet and intranet applications

  . commercial network connections for local area, metropolitan area and wide
    area networks

                     Follow-on Offering of Secondary Shares

  On May 18, 1999, we completed the sale of 18,000,000 shares of Class A common
stock in a secondary offering for the benefit of several selling stockholders
at a sale price of $27 13/16 per share, after giving effect to the two-for-one
stock split described below. We received no proceeds from the sale of these
shares.

Agreements to Acquire Access Communications Holdings, Inc. and S.J. Investments
                                 Holdings, Inc.

  On June 1, 1999, we entered into an Agreement and Plan of Merger with Access
Communications Holdings, Inc., a Utah corporation and certain of the
stockholders of Access, pursuant to which we will acquire Access.

  As a result of the Access merger, the outstanding shares of common stock of
Access will be converted in the aggregate into the right to receive
approximately $23.3 million and 1,939,864 shares of our Class A common stock,
after giving effect to the two-for-one stock split described below. We also
will assume approximately $48.3 million in Access debt.

  In a related transaction, on June 1, 1999, we entered into an Agreement and
Plan of Merger with an affiliated company of Access, S.J. Investments Holdings,
Inc., a Utah corporation, and the stockholders of SJIH, pursuant to which we
will acquire SJIH.

  As a result of the SJIH merger, the outstanding shares of common stock of
SJIH will be converted in the aggregate into the right to receive $25 million
and 1,939,864 shares of our Class A common stock, after giving effect to the
two-for-one stock split described below. We also will assume approximately
$48.3 million in SJIH debt. Consummation of the Access merger and the SJIH
merger are subject to the satisfaction of certain conditions.

  Although two legally separate corporations, Access and SJIH conduct business
as Access Long Distance. Access Long Distance serves business and residential
customers in the states of Arizona, California, Colorado, Florida, Idaho,
Nevada, New Mexico, Oregon, Utah and Washington. As of March 31, 1999, Access
Long Distance served approximately 17,500 commercial customers and
approximately 11,600 residential customers, generating 1998 revenues of $87
million. Access

<PAGE>


Long Distance is a switch-based provider of commercial and residential
telecommunications services, including long distance, toll-free and prepaid
calling cards. In addition, Access Long Distance also sells enhanced toll-free
services.

                             Market Area Expansion

  As a result of the Access Long Distance agreements, we will add four new
states to our current 16-state Midwest and Rocky Mountain market area: Arizona,
New Mexico, Oregon and Washington, and provide coverage of the entire U S WEST
geography. The additional states increase our addressable voice and data market
by approximately 23%.

                            Two-For-One Stock Split

  On June 30, 1999, we declared a two-for-one stock split to be effected in the
form of a stock dividend on our Class A common stock. The record date for the
stock split was July 12, 1999 and the distribution of the additional shares
will take place on July 26, 1999.

               Summary Consolidated Financial and Operating Data

  The information in the following table is based on historical financial
information included in our prior SEC filings, including our annual report on
Form 10-K for the fiscal year ended December 31, 1998. The following summary
financial information should be read in connection with this historical
financial information, including the notes which accompany such financial
information. This historical financial information is considered a part of this
document. See "Where You Can Find More Information." Our audited historical
financial statements as of December 31, 1998 and 1997, and for each of the
three years ended December 31, 1998 were audited by Arthur Andersen LLP,
independent public accountants.

  The information in the table on the following page reflects consolidated
financial information for the following companies we have acquired:

      Ovation Communications, Inc.         March 31, 1999
</TABLE>

  The operations statement data and other financial data in the table include
the operations of these companies beginning on the dates they were acquired.
The balance sheet data in the table include the financial position of these
companies at the end of the periods presented, beginning with the period in
which they were acquired. These acquisitions affect the comparability of the
financial data for the periods presented.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the following table has been
adjusted to reflect the two-for-one stock split.

  The pro forma information presented in the operations statement data and
other financial data in the table reflects the operations of Ovation as if the
Ovation acquisition had occurred on January 1, 1998 and the pro forma
information in the balance sheet data in the table includes Ovation's financial
position as of December 31, 1998.

  The pro forma information presented in the operations statement data and
other financial data in the table includes the effects of the issuance of $300
million principal amount of our 8 3/8% senior notes in March 1998, $300 million
principal amount of our 9 1/2% senior notes in October 1998 and $500 million
principal amount of the 8 1/8% senior notes in February 1999 as if they had
occurred at the beginning of 1998 and the pro forma information presented in
the balance sheet data in the table includes the effects of the issuance of the
8 1/8% senior notes as if it had occurred at the end of 1998.

  The ratio of earnings to fixed charges is calculated as follows: earnings
consist of net loss before income taxes plus fixed charges (excluding
capitalized interest). Fixed charges consist of interest on all debt (including
capitalized interest), amortization of debt discount and deferred loan costs
and the portion of rental expense that is representative of the interest
component of rental expense (deemed to be one-third of rental expense which
management believes is a reasonable approximation of the interest component).
For each of the years ended December 31, 1994, 1995, 1996, 1997 and 1998,
earnings were insufficient to cover fixed charges by $11.4 million, $11.4
million, $22.6 million, $84.4 million and $135.5 million, respectively. For the
three months ended March 31, 1998 and 1999, earnings were insufficient to cover
fixed charges by $32 million and $51.7 million, respectively. On a pro forma
basis, earnings would not have been sufficient to cover fixed charges by $188.6
million and $61.7 million for the year ended December 31, 1998 and the three
months ended March 31, 1999, respectively.

(1) EBITDA consists of operating loss before depreciation, amortization and
    other nonrecurring operating expenses. We have included EBITDA data because
    it is a measure commonly used in the industry. EBITDA is not a measure of
    financial performance under generally accepted accounting principles and
    should not be considered an alternative to net income as a measure of
    performance or to cash flows as a measure of liquidity.

                                  RISK FACTORS

  You should carefully consider the following risk factors and the other
information in this prospectus supplement before investing in our securities.
You should also consider the additional information set forth in our SEC
reports on Forms 10-K, 10-Q and 8-K and in the other documents considered a
part of this prospectus supplement and accompanying prospectus. See "Where You
Can Find More Information."

Fluctuations in the Market Price of Our Class A Common Stock May Make it More
Difficult for Us to Raise Capital.

  The market price of our Class A common stock is extremely volatile and has
fluctuated over a wide range. These fluctuations may impair our ability to
raise capital by offering equity securities. The market price may continue to
fluctuate significantly in response to various factors, including:

  . market conditions in the industry

  . announcements or actions by competitors

  . low trading volume

  . sales of large amounts of our Class A common stock in the public market
    or the perception that such sales could occur

  . quarterly variations in operating results or growth rates

  . changes in estimates by securities analysts

  . regulatory and judicial actions

  . general economic conditions

We May Not Be Able to Successfully Integrate Acquired Companies into Our
Operations, Which Could Slow Our Growth.

  The integration of acquired companies into our operations involves a number
of risks, including:

  . difficulty integrating new operations and personnel

  . diversion of management attention

  . potential disruption of ongoing business

  . inability to retain key personnel or customers

  . inability to successfully incorporate new assets and rights into our
    service offerings

  . inability to maintain uniform standards, controls, procedures and
    policies

  . impairment of relationships with employees, customers or vendors

  Failure to overcome these risks or any other problems encountered in
connection with acquisition transactions could slow our growth or lower the
quality of our services, which could reduce customer demand and adversely
affect our business and our ability to repay the notes.

Continued Rapid Growth of Our Network, Services and Subscribers Could Be Slowed
if We Cannot Manage this Growth.

  We have rapidly expanded and developed our network, services and subscriber
base. For example, we recently announced plans to offer high-speed digital
access and data services. Our expansion and development have placed and will
continue to place significant demands on our management, operational and
financial systems and procedures and controls. We may not be able to manage our
anticipated growth effectively, which would adversely affect our business,
results of operations and financial condition and our ability to repay the
notes.

Further expansion and development will depend on a number of factors,
including:

  . cooperation of the existing local telephone companies

  . regulatory, judicial and governmental developments

  . changes in the competitive climate in which we operate

  . development of customer billing, order processing and network management
    systems

  . availability of financing

  . technological developments

  . availability of rights-of-way, building access and antenna sites

  . existence of strategic alliances or relationships

  . emergence of future opportunities

                                      S-9
<PAGE>

  We will need to continue to improve our operational and financial systems and
our procedures and controls as we grow. We must also develop, train and manage
our employees.

We Expect to Incur Significant Losses Over the Next Several Years.

  If we do not become profitable in the future, the value of our Class A common
stock may fall and we could have difficulty obtaining funds to continue our
operations or to pay amounts due on the notes. We have incurred net losses
every year since we began operations. Since January 1, 1994, our net losses
have been as follows:

We expect to incur net losses during the next several years while we develop
our businesses, expand our fiber optic communications network and develop
wireless services.

Failure to Raise Necessary Capital Could Restrict Our Ability to Develop Our
Network and Services and Engage in Strategic Acquisitions.

  We need significant capital to continue to expand our operations, facilities,
network and services. We cannot assure you that our capital resources will
permit us to fund our planned network deployment and operations or achieve
operating profitability. Our failure to generate or raise sufficient funds may
require us to delay or abandon some of our expansion plans or expenditures,
which could adversely affect our business and competitive position and our
ability to repay the notes.

  As of June 30, 1999, based on our business plan, capital requirements and
growth projections as of that date, we estimated that we would require
approximately $1.4 billion through 2001 to fund our capital expenditures and
operating expenses. Our estimated aggregate capital requirements include the
projected costs of:

  . building our fiber optic communications network, including intra-city
    fiber optic networks

  . expanding operations in existing and new markets

  . developing wireless services

  . funding general corporate expenses

  . integrating acquisitions

  . constructing, acquiring, developing or improving telecommunications
    assets

  Our estimate of future capital requirements is a forward-looking statement
within the meaning of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. The actual amount and timing of our future
capital requirements may differ substantially from our estimate due to factors
such as:

  . strategic acquisition costs and effects of acquisitions on our business
    plan, capital requirements and growth projections

  . unforeseen delays

  . cost overruns

  . engineering design changes

  . changes in demand for our services

  . regulatory, technological or competitive developments

  . new opportunities

  We also expect to evaluate potential acquisitions, joint ventures and
strategic alliances on an ongoing basis. We may require additional financing if
we pursue any of these opportunities.

  We may meet any additional capital needs by issuing additional debt or equity
securities or borrowing funds from one or more lenders. We cannot assure you
that we will have timely access to additional financing sources on acceptable
terms. If we do not have such access, we may not be able to expand our markets,
operations, facilities, network and services through acquisitions as we intend.

Our High Level of Debt Could Limit Our Flexibility in Responding to Business
Developments and Put Us at a Competitive Disadvantage.

  We have substantial debt, which could adversely affect us in a number of
ways, including:

  . limiting our ability to obtain necessary financing in the future

                                      S-10
<PAGE>

  . limiting our flexibility to plan for, or react to, changes in our
    business

  . requiring us to use a substantial portion of our cash flow from
    operations to pay our debt obligations rather than for other purposes,
    such as working capital or capital expenditures

  . making us more highly leveraged than some of our competitors, which may
    place us at a competitive disadvantage

  . making us more vulnerable to a downturn in our business

  As of March 31, 1999, we had $1.8 billion of long-term debt and $785.4
million of stockholders' equity. As a result, we expect our fixed charges to
exceed our earnings for the foreseeable future.

Covenants in Debt Instruments Restrict Our Capacity to Borrow and Invest, Which
Could Impair Our Ability to Expand or Finance Our Operations.

  The indentures governing the terms of our long-term debt, including the notes
we are offering, impose operating and financial restrictions that limit our
discretion on some business matters, which could make it more difficult for us
to expand, finance our operations or engage in other business activities that
may be in our interest. These restrictions limit or prohibit our ability to:

  . incur additional debt

  . pay dividends or make other distributions

  . make investments or other restricted payments

  . enter into sale and leaseback transactions

  . pledge or mortgage assets or otherwise create liens

  . enter into transactions with related persons

  . sell assets

  . consolidate, merge or sell all or substantially all of our assets

If we fail to comply with these restrictions, all of our long-term debt could
become immediately due and payable.

Our Dependence on Regional Bell Operating Companies to Provide Most of Our
Communications Services Could Make it Harder for Us to Offer Our Services at a
Profit.

  We depend on the regional Bell operating companies to provide most of our
core local and some of our long distance services. Today, without using the
communications facilities of these companies, we could not provide bundled
local and long distance services to most of our customers. Because of this
dependence, our communications services are highly susceptible to changes in
the conditions for access to these facilities and we may therefore have
difficulty offering our services at profitable and competitive rates.

  U S WEST Communications, Inc., Ameritech Corporation and Southwestern Bell
Telephone Company are our primary suppliers of local lines to our customers and
communications services that allow us to transfer and connect calls. Their
communications facilities allow us to provide (1) local service, (2) long
distance service and (3) private lines dedicated to our customers' use. If
these or other companies deny or limit our access to their communications
network elements or wholesale services, we may not be able to offer profitable
communications services.

  Our plans to provide local service using our own communications network
equipment also depend on the regional Bell operating companies. In order to
interconnect our network equipment and other communications facilities to
network elements controlled by the regional Bell operating companies, we must
first negotiate and enter into interconnection agreements with them.
Interconnection obligations imposed on the regional Bell operating companies by
the Telecommunications Act of 1996 have been, and continue to be, subject to a
variety of legal proceedings, which could affect our ability to obtain
interconnection agreements on acceptable terms. We cannot assure you that we
will succeed in obtaining interconnection agreements on terms that would permit
us to offer local services using our own communications network facilities at
profitable and competitive rates.

<PAGE>

Actions by U S WEST May Make it More Difficult for Us to Offer Our
Communications Services.

  U S WEST has introduced several measures that may make it more difficult for
us to offer our communications services. For example, in February 1996, U S
WEST filed tariffs and other notices with the public utility commissions in its
fourteen-state service region to limit future Centrex access to its switches.
Centrex access allows us to aggregate lines, have control over several
characteristics of those lines and provide a set of standard features on those
lines. We use U S WEST's Centrex services to provide most of our local
communications services in U S WEST's service territories.

  In January 1997, U S WEST also proposed interconnection surcharges in several
of the states in its service region, which would increase our costs of
providing communications services in those states.

  We have challenged or are challenging these actions by U S WEST before the
FCC or applicable state public utility commissions. We cannot assure you we
will succeed in our challenges to these or other actions by U S WEST that would
prevent or deter us from using U S WEST's Centrex service or communications
network elements. If U S WEST successfully withdraws or limits our access to
Centrex services in any jurisdiction, we may not be able to offer
communications services in that jurisdiction, which could adversely affect our
business and our ability to repay the notes.

  We anticipate that U S WEST will also pursue legislation in states within our
target market area to reduce state regulatory oversight over its rates and
operations. If adopted, these initiatives could make it more difficult for us
to challenge U S WEST's actions in the future.

Competition in the Communications Services Industry Could Cause Us to Lose
Customers and Revenue and Could Make it More Difficult for Us to Enter New
Markets.

  We face intense competition in all of our markets. This competition could
result in loss of customers and lower revenue for us. It could also make it
more difficult for us to enter new markets. Existing local telephone companies,
including U S WEST, Ameritech, Southwestern Bell and GTE, currently dominate
their local telecommunications markets. Three major competitors, AT&T, MCI
WorldCom and Sprint, dominate the long distance market. Hundreds of other
companies also compete in the long distance marketplace. AT&T, MCI WorldCom and
Sprint also offer local telecommunications services in many locations.

  We also compete with other communications services companies which, like us,
compete with the existing local telephone companies in some markets.

  Other competitors may include cable television companies, providers of
communications network facilities dedicated to particular customers, providers
of digital access and data services, microwave and satellite carriers, wireless
telecommunications providers, private networks owned by large end-users, and
telecommunications management companies.

  These and other firms may enter the markets where we focus our sales efforts.
Many of our existing and potential competitors have financial and other
resources far greater than our own. In addition, the trend toward mergers and
strategic alliances in the communications industry may strengthen some of our
competitors, which could put us at a significant competitive disadvantage and
adversely affect our ability to repay the notes.

We May Not Succeed in Developing or Making a Profit from Wireless Services.

  Our proposal to offer wireless services involves a high degree of risk and
will impose significant demands on our management and financial resources.
Developing wireless services may require us to, among other things, spend
substantial time and money to acquire, build and test a wireless infrastructure
and enter into roaming arrangements with wireless operators in other markets.
We may not succeed in developing wireless services. Even if we spend
substantial amounts to develop wireless services, we may not make a profit from
wireless operations.

                                      S-12
<PAGE>

  Our ability to successfully offer wireless services will also depend on a
number of factors beyond our control, including:

  . changes in communications service rates charged by other companies

  . changes in the supply and demand for wireless services due to competition
    with other wireline and wireless operators in the same geographic area

  . changes in the federal, state or local regulatory requirements affecting
    the operation of wireless systems

  . changes in wireless technologies that could render obsolete the
    technology and equipment we choose for our wireless services

Competition in the Wireless Telecommunications Industry Could Make it Harder
for Us to Successfully Offer Wireless Services.

  The wireless telecommunications industry is experiencing increasing
competition and significant technological change. This will make it harder for
us to gain a share of the wireless communications market. We expect up to eight
wireless competitors in each of our target wireless markets. We could face
additional competition from mobile satellite services.

  Many of our potential wireless competitors have financial and other resources
far greater than our own and have more experience testing new or improved
products and services. In addition, several wireless competitors operate or
plan to operate, wireless telecommunications systems that encompass most of the
United States, which could give them a significant competitive advantage,
particularly if we only offer regional wireless services.

The Success of Our Communications Services Will Depend on Our Ability to Keep
Pace with Rapid Technological Changes in Our Industry.

  Communications technology is changing rapidly. These changes influence the
demand for our services. We need to be able to anticipate these changes and to
develop new and enhanced products and services quickly enough for the changing
market. This will determine whether we can continue to increase our revenues
and number of subscribers and be competitive. Failure to adapt to these changes
may adversely affect our business and our ability to repay the notes.

The Loss of Key Personnel Could Weaken Our Technical and Operational Expertise,
Delay Our Introduction of New Services or Entry into New Markets and Lower the
Quality of Our Service.

  We may not be able to attract, develop, motivate and retain experienced and
innovative personnel. There is intense competition for qualified personnel in
our business. The loss of the services of key personnel, or the inability to
attract additional qualified personnel, could cause us to make less successful
strategic decisions, which could hinder the introduction of new services or the
entry into new markets. We could also be less prepared for technological or
marketing problems, which could reduce our ability to serve our customers and
lower the quality of our services. As a result, our financial condition could
worsen and could adversely affect our ability to repay the notes.

  Our future success depends on the continued employment of our senior
management team, particularly Clark E. McLeod, our Chairman and Chief Executive
Officer, and Stephen C. Gray, our President and Chief Operating Officer. We do
not have term employment agreements with these employees.

Failure to Obtain and Maintain Necessary Permits and Rights-of-Way Could Delay
Installation of Our Networks and Interfere with Our Operations.

  To obtain access to rights-of-way needed to install our fiber optic cable, we
must reach agreements with state highway authorities, local governments,
transit authorities, local telephone companies, other utilities, railroads,
long distance carriers and other parties. The failure to obtain or maintain any
rights-of-way could delay our planned network expansion, interfere with our
operations and adversely affect our business and our ability to repay the
notes. For example, if we lose access to a right-of-way, we may need to spend
significant sums to remove and relocate our facilities.

Government Regulation May Increase Our Cost of Providing Services, Slow Our
Expansion into New Markets and Subject Our Services to Additional Competitive
Pressures.

  Our facilities and services are subject to federal, state and local
regulation. The time and expense of complying with these regulations could slow
down our expansion into new markets, increase

                                      S-13
<PAGE>

our costs of providing services and subject them to additional competitive
pressures. One of the primary purposes of the Telecommunications Act of 1996
was to open the local telephone services market to competition. While this has
presented us with opportunities to enter local telephone markets, it also has
provided important benefits to the existing local telephone companies, such as
the ability, under specified conditions, to provide out-of-region long distance
service to customers in their respective regions. In addition, we need to
obtain and maintain licenses, permits and other regulatory approvals in
connection with some of our services. Any of the following could adversely
affect our business and our ability to repay the notes:

  . failure to maintain proper federal and state tariffs

  . failure to maintain proper state certifications

  . failure to comply with federal, state or local laws and regulations

  . failure to obtain and maintain required licenses and permits

  . burdensome license or permit requirements to operate in public rights-of-
    way

  . burdensome or adverse regulatory requirements

Our Management and Principal Stockholders Can Control McLeodUSA and May Have
Different Interests Than the Noteholders.

  Certain decisions concerning our operations or financial structure may
present conflicts of interests between our stockholders and the holders of the
notes. For example, if we encounter financial difficulties or are unable to pay
our debts as they mature, the interests of our stockholders might conflict with
those of the holders of the notes. In addition, our stockholders may have an
interest in pursuing acquisitions, divestitures, financings or other
transactions that, in their judgment could enhance their equity investment,
even though such transactions might involve risk to the holders of the notes.

  As of July 1, 1999, Interstate Energy Corporation, M/C Investors L.L.C.,
Media/Communications Partners III Limited Partnership, Richard A. Lumpkin and
various trusts for the benefit of his family, Clark and Mary McLeod, and our
directors and executive officers beneficially owned approximately 40% of our
outstanding Class A common stock. Because these stockholders can collectively
control management policy and may be able to control corporate actions
requiring a stockholder vote, any such conflict of interest may be resolved in
favor of our stockholders to the detriment of the holders of the notes.

Computer Systems May Malfunction and Interrupt Our Services if We and Our
Suppliers Do Not Attain Year 2000 Readiness.

  We and our major suppliers of communications services and network elements
rely greatly on computer systems and other technological devices. These may not
be capable of recognizing January 1, 2000 or subsequent dates. This problem
could cause any or all of our systems or services to malfunction or fail.

  We are reviewing our computer systems and programs and other technological
devices to determine which are not capable of recognizing the Year 2000 and to
verify system readiness for the millennium date. The review covers all of our
operations and is centrally managed. This review may not be sufficient,
however, to prevent interruptions to our systems and services.

  Some of our critical operations and services depend on other companies. For
example, we depend on the existing local telephone companies, primarily the
regional Bell operating companies, to provide most of our local and some of our
long distance services. To the extent U S WEST, Ameritech or Southwestern Bell
fail to address Year 2000 issues which might interfere with their ability to
fulfill their obligations to us, it could interfere with our operations. If we,
our major vendors, our material service providers or our customers fail to
address Year 2000 issues in a timely manner, our business, results of
operations, financial condition and ability to repay the notes could be
adversely affected.

We Depend upon Payments from Our Subsidiaries to Pay Principal and Interest on
Our Debt Obligations.

  We are a holding company, which means we conduct all of our operations and
derive all of our operating income from our subsidiaries. Our ability to pay
our obligations, including our obligation to pay principal and interest on the
notes, depends on receiving dividends and other payments from our subsidiaries,
raising additional funds in a public or private equity or debt offering or
selling assets. Our subsidiaries constitute separate legal entities and have no
obligation to pay any amounts due on the notes or to make funds available to
us. Our subsidiaries' ability to pay dividends or make other payments or
advances to us will depend on their operating results and the requirements of
applicable law.

The Notes Are Subordinate to Our Subsidiaries' Obligations and Our Own Secured
Obligations.

  The notes will be effectively subordinated in right of payment to all
liabilities of our subsidiaries. This means that in the event of a bankruptcy,
liquidation or reorganization, our subsidiaries must pay their creditors in
full before we could use their assets to pay you. As of March 31, 1999, our
subsidiaries had total liabilities after the elimination of loans and advances
from us to our subsidiaries of approximately $325.0 million. In addition, the
indenture that will govern the notes and the indentures governing our 10 1/2%
senior discount notes, 9 1/4% senior notes, 8 3/8% senior notes, 9 1/2% senior
notes and 8 1/8% senior notes, which we refer to collectively as our
indentures, permit us and our subsidiaries to incur additional debt.

  The notes will be unsecured and will be subordinated to our secured debt.
This means if we default on any of our secured debt, our secured creditors
could foreclose on their collateral and receive
payment out of the proceeds of that collateral before we could use those assets
to pay you. If the value of
the collateral is less than the amount owed, our secured creditors will have
equal rights with you to our remaining assets. As of March 31, 1999, we had
total secured debt of approximately $52.1 million. The
indentures permit us and our subsidiaries to incur additional secured debt,
including unlimited purchase money debt and up to $250 million under one or
more credit facilities.

There Is No Established Trading Market for the Notes, Which Could Make it More
Difficult for You to Sell Your Notes and Could Adversely Affect Their Price.

  The notes constitute a new issue of securities for which no established
trading market exists. Consequently, it may be more difficult for you to sell
your notes. If notes are traded after their initial issuance, they may trade at
a discount, depending upon:

  . our financial condition

  . prevailing interest rates

  . the market for similar securities

  . other factors beyond our control, including general economic conditions.

  We do not intend to apply for a listing or quotation of the notes on any
securities exchange. The underwriters have informed us that they intend to make
a market in the notes. However, the underwriters have no obligation to do so,
and may discontinue any market-making activities at any time without notice. We
cannot assure you of the development or liquidity of any trading market for the
notes following the offering.

                                USE OF PROCEEDS

  We will use the net proceeds from the sale of the notes along with funds
available from prior offerings and from other financing sources: (1) to fund
development and construction costs of our fiber optic network, including intra-
city fiber optic networks, and construction, acquisition, development and
improvement of telecommunications assets; (2) to fund market expansion
activities in existing and new markets as well as acquisitions, joint ventures
and strategic alliances; (3) to fund development, construction and operations
necessary to include wireless services as part of our communications services;
and (4) for additional working capital and other general corporate purposes,
including funding operating deficits and net losses.

  The operations statement data and other financial data in the table include
the operations of these companies beginning on the dates they were acquired.
The balance sheet data in the table include the financial position of these
companies at the end of the periods presented, beginning with the period in
which they were acquired. These acquisitions affect the comparability of the
financial data for the periods presented.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the following table has been
adjusted to reflect the two-for-one stock split.

  The pro forma information presented in the operations statement data and
other financial data in the table reflects the operations of Ovation as if the
Ovation acquisition had occurred on January 1, 1998 and the pro forma
information in the balance sheet data in the table includes Ovation's financial
position as of December 31, 1998.

  The pro forma information presented in the operations statement data and
other financial data in the table includes the effects of the issuance of $300
million principal amount of our 8 3/8% senior notes in March 1998, $300 million
principal amount of our 9 1/2% senior notes in October 1998 and $500 million
principal amount of the 8 1/8% notes in February 1999 as if they had occurred
at the beginning of 1998 and the pro forma information presented in the balance
sheet data in the table includes the effects of the issuance of the 8 1/8%
notes as if it had occurred at the end of 1998.

  The ratio of earnings to fixed charges is calculated as follows: earnings
consist of net loss before income taxes plus fixed charges (excluding
capitalized interest). Fixed charges consist of interest on all debt (including
capitalized interest), amortization of debt discount and deferred loan costs
and the portion of rental expense that is representative of the interest
component of rental expense (deemed to be one-third of rental expense which
management believes is a reasonable approximation of the interest component).
For each of the years ended December 31, 1994, 1995, 1996, 1997 and 1998,
earnings were insufficient to cover fixed charges by $11.4 million, $11.4
million, $22.6 million, $84.4 million and $135.5 million, respectively. For the
three months ended March 31, 1998 and 1999, earnings were insufficient to cover
fixed charges by $32 million and $51.7 million, respectively. On a pro forma
basis, earnings would not have been sufficient to cover fixed charges by $188.6
and $61.7 million for the year ended December 31, 1998 and the three months
ended March 31, 1999, respectively.

(1) EBITDA consists of operating loss before depreciation, amortization and
    other nonrecurring operating expenses. We have included EBITDA data because
    it is a measure commonly used in the industry. EBITDA is not a measure of
    financial performance under generally accepted accounting principles and
    should not be considered an alternative to net income as a measure of
    performance or to cash flows as a measure of liquidity.

                            PRO FORMA FINANCIAL DATA

  The following unaudited pro forma financial information has been prepared to
give effect to:

 .the issuance of $300 million aggregate principal amount of our 8 3/8% senior
       notes in March 1998

 .the issuance of $300 million aggregate principal amount of our 9 1/2% senior
     notes in October 1998

 .the issuance of $500 million aggregate principal amount of our 8 1/8% senior
     notes in February 1999

   .our acquisition of Ovation Communications, Inc. in March 1999

  The Unaudited Pro Forma Condensed Consolidated Statements of Operations
reflects the Ovation acquisition using the purchase method of accounting, and
assumes that the Ovation acquisition and the issuance of the 8 3/8% senior
notes, the 9 1/2% senior notes and the 8 1/8% senior notes were consummated at
the beginning of 1998. The unaudited pro forma financial information is derived
from and should be read in conjunction with our consolidated financial
statements, Ovation's consolidated financial statements and the related notes
thereto incorporated by reference in this prospectus. The pro forma adjustments
are based upon available information and assumptions that management believes
to be reasonable. Depreciation and amortization were adjusted to include
amortization of intangibles acquired in the Ovation acquisition. The acquired
intangibles will be amortized over periods ranging from 3 to 30 years. For
purposes of this pro forma presentation, the issuance of the 8 3/8% senior
notes, the 9 1/2% senior notes and the 8 1/8% senior notes are collectively
referred to as the "Notes Offerings."

  The adjustments for the Ovation acquisition reflect the preliminary
allocation of the net purchase price of Ovation to the assets of Ovation,
including intangible assets, and record the payment of $121.3 million in cash
and the issuance of 11,193,234 shares of our Class A common stock (as adjusted
for the two-for-one stock split described below) valued at $16.88 per share (as
adjusted for the two-for-one stock split described below). The value of $16.88
per share represents the average closing price of our Class A common stock on
the Nasdaq National Market for the eleven trading days beginning five days
prior to the date the agreement was announced, January 7, 1999, and ending five
days after such announcement. The adjustments include the elimination of the
Ovation equity components, including common stock, treasury stock, other
capital and retained deficit.

  On June 30, 1999, we announced that our board of directors had declared a
two-for-one stock split to be effected in the form of a stock dividend. The
record date for the stock split was July 12, 1999. Stockholders of record at
the market close on that date will receive one additional share of our Class A
common stock for each share held. Distribution of the additional shares will
take place on July 26, 1999. All information in the Pro Forma Financial Data
has been adjusted to reflect the two-for-one stock split.

  We have provided this unaudited pro forma financial data for informational
purposes only. This data does not necessarily indicate the operating results
that would have occurred had the Ovation acquisition been consummated at the
beginning of 1998, nor does it necessarily indicate future operating results or
financial position.

(1) EBITDA consists of operating loss before depreciation, amortization and
    other nonrecurring operating expenses. We have included EBITDA data because
    it is a measure commonly used in the industry. EBITDA is not a measure of
    financial performance under generally accepted accounting principles and
    should not be considered an alternative to net income as a measure of
    performance or to cash flows as a measure of liquidity.

                            DESCRIPTION OF THE NOTES

General

  The notes will be issued under an indenture, which we refer to as the base
indenture, as supplemented by a first supplemental indenture, which we refer to
as the supplemental indenture, between McLeodUSA and United States Trust
Company of New York, as trustee. We refer to the base indenture and the
supplemental indenture taken together as the indenture. For purposes of this
description of the notes, references to "McLeodUSA," "we," "our" or "us" refers
to McLeodUSA Incorporated and does not include its subsidiaries except for
purposes of financial data determined on a consolidated basis.

  The terms of the notes include those stated in the indenture and those made a
part of the indenture by reference to the Trust Indenture Act of 1939 as in
effect on the date of the base indenture. The notes will be subject to all of
those terms, and holders of the notes are referred to the indenture and the
Trust Indenture Act for a complete statement of the applicable terms. A copy of
the indenture is available from McLeodUSA on request. The statements and
definitions of terms under this caption relating to the notes and the indenture
are summaries and do not purport to be complete. These summaries make use of
terms defined in the indenture and are qualified in their entirety by express
reference to the indenture. Some of the terms used in this description are
defined below under "--Definitions."

  The notes will rank equal in right of payment with our 10 1/2% senior
discount notes, 9 1/4% senior notes, 8 3/8% senior notes, the 9 1/2% senior
notes and the 8 1/8% senior notes, and all other existing and future senior
unsecured indebtedness of McLeodUSA and will rank senior in right of payment to
all existing and future subordinated indebtedness of McLeodUSA. As of March 31,
1999, McLeodUSA had no outstanding subordinated indebtedness and, other than
our 10 1/2% senior discount notes, the 9 1/4% senior notes, 8 3/8% senior
notes, 9 1/2% senior notes and 8 1/8% senior notes, had no outstanding
indebtedness that would rank equal with the notes. For a description of these
notes and other outstanding indebtedness of McLeodUSA, see "Other
Indebtedness." The notes will not be secured by any assets and will be
effectively subordinated to any existing and future secured indebtedness of
McLeodUSA and its subsidiaries, including any Senior Credit Facility or
Qualified Receivable Facility, to the extent of the value of the assets
securing such indebtedness. As of March 31, 1999, the total secured
indebtedness of McLeodUSA and its subsidiaries was approximately $52.1 million.

  The operations of McLeodUSA are conducted through its subsidiaries and,
therefore, McLeodUSA depends upon cash flow from those entities to meet its
obligations. The subsidiaries will have no direct obligation to pay amounts due
on the notes and will not guarantee the notes. As a result, the notes will be
effectively subordinated to all existing and future third-party indebtedness,
including any Senior Credit Facility or any applicable Qualified Receivable
Facility, and other liabilities of McLeodUSA's subsidiaries, including trade
payables. As of March 31, 1999, the total liabilities of McLeodUSA's
subsidiaries, after the elimination of loans and advances by McLeodUSA to its
subsidiaries, were approximately $325.0 million. Any rights McLeodUSA or its
creditors may have, including the holders of notes, to participate in the
assets of any of McLeodUSA's subsidiaries upon any liquidation or
reorganization of any such subsidiary will be subject to the prior claims of
that subsidiary's creditors, including trade creditors.

Principal, Maturity and Interest

  The notes will be limited in principal amount to $400 million and will mature
on        , 2009. Interest on the notes will accrue at the rate of   % per
annum and will be payable in cash semi-annually in arrears on       and
of each year, commencing       , 2000. Interest will be computed on the basis
of a 360-day year comprised of twelve 30-day months.

  Principal and interest will be payable at the office of the Paying Agent but,
at the option of McLeodUSA, interest may be paid by check mailed to the
registered holders at their registered addresses. The notes will be issued
without coupons and in fully registered form only, in minimum denominations of
$1,000 and any integral multiples of $1,000 in excess thereof. Unless otherwise
designated by McLeodUSA, McLeodUSA's office or agency in New York will be the
office of the trustee maintained for such purpose. The notes will be issued
only against payment therefor in immediately available funds.

                                      S-23
<PAGE>

Book-Entry System

  The notes will initially be issued in the form of one or more Global
Securities, as defined in the indenture, held in book-entry form. The notes
will be deposited with the trustee as custodian for the Depository, and the
Depository or its nominee will initially be the sole registered holder of the
notes for all purposes under the indenture. Except as set forth below, a Global
Security may not be transferred except as a whole by the Depository to a
nominee of the Depository or by a nominee of the Depository to the Depository.

  The notes that are issued as described below under "--Certificated Notes"
will be issued in definitive form. Upon the transfer of a note in definitive
form, such note will, unless the Global Security has previously been exchanged
for notes in definitive form, be exchanged for an interest in the Global
Security representing the principal amount notes being transferred.

  Upon the issuance of a Global Security, the Depository or its nominee will
credit, on its internal system, the accounts of persons holding through it with
the individual beneficial interests in such Global Security representing the
respective principal amounts of the notes held by such persons. Ownership of
beneficial interests in a Global Security will be limited to persons that have
accounts with the Depository, referred to herein as participants, or to persons
that may hold interests through participants. Ownership of beneficial interests
by participants in a Global Security will be shown on, and the transfer of that
ownership interest will be effected only through, records maintained by the
Depository or its nominee for such Global Security. Ownership of beneficial
interests in such Global Security by persons that hold through participants
will be shown on, and the transfer of that ownership interest within such
participant will be effected only through, records maintained by such
participant. The laws of some jurisdictions require that some purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Security.

  Payment of principal of, premium, if any, and interest on notes represented
by any such Global Security will be made to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole holder of the notes
represented thereby for all purposes under the indenture. None of McLeodUSA,
the trustee, any agent of McLeodUSA or the underwriters will have any
responsibility or liability for:

  1. any aspect of the Depository's reports relating to or payments made on
     account of beneficial ownership interests in a Global Security
     representing any notes or for maintaining, supervising or reviewing any
     of the Depository's records relating to such beneficial ownership
     interests or

  2. any other matter relating to the actions and practices of the Depository
     or any of its participants.

  McLeodUSA has been advised by the Depository that upon receipt of any payment
of principal of, premium on, if any, or interest on any Global Security, the
Depository will immediately credit, on its book-entry registration and transfer
system, the accounts of participants with payments in amounts proportionate to
their respective beneficial interests in the principal or face amount of such
Global Security, as shown on the records of the Depository. McLeodUSA expects
that payments by participants to owners of beneficial interests in a Global
Security held through such participants will be governed by standing
instructions and customary practices as is now the case with securities held
for customer accounts registered in "street name" and will be the sole
responsibility of such participants.

  So long as the Depository or its nominee is the registered owner or holder of
such Global Security, the Depository or such nominee, as the case may be, will
be considered the sole owner or holder of the notes represented by such Global
Security for the purposes of receiving payment on the notes, receiving notices
and for all other purposes under the indenture and the notes. Beneficial
interests in notes will be evidenced only by, and transfers thereof will be
effected only through, records maintained by the Depository and its
participants. Except as provided above, owners of beneficial interests in a
Global Security will not be entitled to, and will

                                      S-24
<PAGE>

not be considered the holders of, such Global Security for any purposes under
the indenture. Accordingly, each person owning a beneficial interest in a
Global Security must rely on the procedures of the Depository and, if such
person is not a participant, on the procedures of the participant through which
such person owns its interest, to exercise any rights of a holder under the
indenture. McLeodUSA understands that, under existing industry practices, in
the event that McLeodUSA requests any action of holders or that an owner of a
beneficial interest in a Global Security desires to give or take any action
that a holder is entitled to give or take under the indenture, the Depository
would authorize the participants holding the relevant beneficial interest to
give or take such action, and such participants would authorize beneficial
owners owning through such participants to give or take such action or would
otherwise act upon the instructions of beneficial owners owning through them.

  The Depository has advised McLeodUSA that it will take any action permitted
to be taken by a holder of notes, including the presentation of notes for
exchange as described below, only at the direction of one or more participants
to whose account with the Depository interests in the Global Security are
credited and only in respect of such portion of the aggregate principal amount
of the notes as to which such participant or participants has or have given
such direction.

  The Depository has advised McLeodUSA that the Depository is a limited-purpose
trust company organized under the Banking Law of the State of New York, a
"banking organization" within the meaning of New York Banking Law, a member of
the Federal Reserve System, a "clearing corporation" within the meaning of the
New York Uniform Commercial Code and a "clearing agency" registered under the
Securities Exchange Act. The Depository was created to hold the securities of
its participants and to facilitate the clearance and settlement of securities
transactions among its participants in such securities through electronic book-
entry changes in accounts of the participants, thereby eliminating the need for
physical movement of securities certificates. The Depository's participants
include securities brokers and dealers including the underwriters, banks, trust
companies, clearing corporations and various other organizations some of whom,
and/or their representatives, own the Depository. Access to the Depository's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship
with a participant, either directly or indirectly, and dealers including the
underwriterss, banks, trust companies, clearing corporations and various other
organizations some of whom, and/or their representatives, own the Depository.
Access to the Depository's book-entry system is also available to others, such
as banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly.

  The information in this section concerning the Depository and the
Depository's book-entry system has been obtained from sources that McLeodUSA
believes to be reliable, but McLeodUSA takes no responsibility for the accuracy
thereof.

Certificated Notes

  The notes represented by a Global Security are exchangeable for certificated
notes only if:

  . the Depository notifies McLeodUSA that it is unwilling or unable to
    continue as a depository for such Global Security or if at any time the
    Depository ceases to be a clearing agency registered under the Securities
    Exchange Act, and a successor depository is not appointed by within 90
    days

  . McLeodUSA executes and delivers to the trustee a notice that such Global
    Security shall be so transferable, registrable and exchangeable, and such
    transfer shall be registrable, or

  . there shall have occurred and be continuing an Event of Default with
    respect to the notes represented by such Global Security

Any Global Security that is exchangeable for certificated notes pursuant to the
preceding sentence will be transferred to, and registered and exchanged for,
certificated notes in authorized denominations and registered in such names as
the Depository or its nominee holding such Global Security may direct. Subject
to the

                                      S-25
<PAGE>

foregoing, a Global Security is not exchangeable, except for a Global Security
of like denomination to be registered in the name of the Depository or its
nominee. In the event that a Global Security becomes exchangeable for
certificated notes:

  . certificated notes will be issued only in fully registered form in
    denominations of $1,000 or integral multiples thereof

  . payment of principal, any repurchase price, and interest on the
    certificated notes will be payable, and the transfer of the certificated
    notes will be registrable, at the office or agency we maintain for such
    purposes, and

  . no service charge will be made for any issuance of the certificated
    notes, although McLeodUSA may require payment of a sum sufficient to
    cover any tax or governmental charge imposed in connection therewith

Optional Redemption

  The notes will be subject to redemption at the option of McLeodUSA, in whole
or in part, at any time on or after      , 2004 and prior to maturity, upon not
less than 30 nor more than 60 days' notice, in amounts of $1,000 or an integral
multiple of $1,000, at the redemption prices, expressed as percentages of
principal amount, set forth below, plus accrued and unpaid interest thereon, if
any, if redeemed during the twelve month periods beginning        of the years
indicated below:

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

   2007 and after....................................................  100.000%
</TABLE>

  The notes will be redeemable prior to      , 2002 only in the event that
McLeodUSA receives net proceeds from the sale of its common stock in a
Strategic Equity Investment on or before      , 2002, in which case McLeodUSA
may, at its option, use all or a portion of any such net proceeds to redeem up
to 33 1/3% of the originally issued principal amount of the notes; provided,
that at least 66 2/3% of the originally issued principal amount of the notes
would remain outstanding after such redemption. Such redemption must occur on a
Redemption Date within 90 days of such sale and upon not less than 30 nor more
than 60 days' notice mailed to each holder of notes to be redeemed at such
holder's address appearing in the Security Register, in amounts of $1,000 or an
integral multiple of $1,000 at a redemption price equal to    % of the
principal amount of the notes so redeemed, plus accrued and unpaid interest
thereon, if any, to but excluding the Redemption Date.

  If less than all of the notes are to be redeemed, the trustee shall select,
in such manner as it shall deem fair and appropriate, the particular notes to
be redeemed or any portion thereof that is an integral multiple of $1,000.

Mandatory Redemption

  Except as set forth under "--Repurchase at the Option of Holders upon a
Change of Control" and "--Asset Sales," McLeodUSA is not required to make
mandatory redemption payments or sinking fund payments with respect to the
notes.

Repurchase at the Option of Holders upon a Change of Control

  Upon the occurrence of a Change of Control, each holder shall have the right
to require McLeodUSA to repurchase all or any part, equal to $1,000 principal
amount or an integral multiple thereof, of such holder's notes pursuant to the
offer described below (the "Change of Control Offer") at a purchase price (the
"Change of Control Purchase Price") equal to 101% of the principal amount of
the notes plus accrued and unpaid interest, if any, to any Change of Control
Payment Date.


                                      S-26
<PAGE>

  Within 30 days following any Change of Control, McLeodUSA or the trustee, at
the request and expense of McLeodUSA shall mail a notice to each holder
stating:

  . that a Change of Control Offer is being made pursuant to the covenant
    described under "--Repurchase at the Option of Holders upon a Change of
    Control" and that all notes timely tendered will be accepted for payment

  . the Change of Control Purchase Price and the purchase date (the "Change
    of Control Payment Date"), which shall be no earlier than 30 days nor
    later than 60 days from the date such notice is mailed

  . that any notes or portions thereof not tendered or accepted for payment
    will continue to accrue interest

  . that, unless McLeodUSA defaults in the payment of the Change of Control
    Purchase Price, all notes or portions thereof accepted for payment
    pursuant to the Change of Control Offer shall cease to accrue interest
    from and after the Change of Control Payment Date

  . that holders electing to have any notes or portions thereof purchased
    under a Change of Control Offer will be required to surrender their notes
    before the close of business on the third Business Day preceding the
    Change of Control Payment Date

  . that holders will be entitled to withdraw their election if the Paying
    Agent receives, not later than the close of business on the second
    Business Day preceding the Change of Control Payment Date, a telegram,
    telex, facsimile transmission or letter setting forth the name of the
    holder, the principal amount of notes delivered for purchase, and a
    statement that such holder is withdrawing its election to have such notes
    or portions thereof purchased

  . that holders electing to have notes purchased under the Change of Control
    Offer must specify the principal amount that is being tendered for
    purchase, which principal amount must be $1,000 or an integral multiple
    thereof

  . that holders whose notes are being purchased only in part will be issued
    new notes equal in principal amount to the unpurchased portion of the
    note or notes surrendered, which unpurchased portion must be equal to
    $1,000 in principal amount or an integral multiple thereof, and

  . any other information necessary to enable any holder to tender notes and
    to have such notes purchased pursuant to the indenture

  McLeodUSA will comply with the requirements of Section 14(e) under the
Securities Exchange Act and any other securities laws or regulations, to the
extent such laws and regulations are applicable, in connection with the
repurchase of notes under a Change of Control Offer.

  On the Change of Control Payment Date, McLeodUSA will:

  .accept for payment notes or portions thereof properly tendered under the
   Change of Control Offer

  . irrevocably deposit with the Paying Agent in immediately available funds
    an amount equal to the Change of Control Purchase Price in respect of all
    notes or portions thereof accepted, and

  . deliver, or cause to be delivered, to the trustee the notes accepted
    together with an Officers' Certificate listing the notes or portions
    thereof tendered to McLeodUSA and accepted for payment

The Paying Agent shall promptly mail to each holder of accepted notes payment
in an amount equal to the Change of Control Purchase Price for such notes, and
the trustee shall promptly authenticate and mail to each holder a new note
equal in principal amount to any unpurchased portion of the notes surrendered,
if any; provided that each such new note shall be in a principal amount of
$1,000 or any integral multiple thereof.

  The existence of the holders' right to require, subject to several
conditions, McLeodUSA to repurchase notes upon a Change of Control may deter a
third party from acquiring McLeodUSA in a transaction that constitutes a Change
of Control. If a Change of Control Offer is made, there can be no assurance
that McLeodUSA will have sufficient funds to pay the Change of Control Purchase
Price for all notes tendered by holders seeking to accept the Change of Control
Offer. In addition, instruments governing other indebtedness of McLeodUSA may
prohibit McLeodUSA from purchasing any notes prior to their Stated Maturity,
including

                                      S-27
<PAGE>

under a Change of Control Offer. In the event that a Change of Control Offer
occurs at a time when McLeodUSA does not have sufficient available funds to pay
the Change of Control Purchase Price for all notes tendered pursuant to such
offer or at a time when McLeodUSA is prohibited from purchasing the notes, and
McLeodUSA is unable either to obtain the consent of the holders of the relevant
indebtedness or to repay such indebtedness, an Event of Default would occur
under the indenture. In addition, one of the events that constitutes a Change
of Control under the indenture is a sale, conveyance, transfer or lease of all
or substantially all of the property of McLeodUSA. The indenture is governed by
New York law, and there is no established definition under New York law of
"substantially all" of the assets of a corporation. Accordingly, if McLeodUSA
were to engage in a transaction in which it disposed of less than all of its
assets, a question of interpretation could arise as to whether such disposition
was of "substantially all" of the assets of McLeodUSA and whether McLeodUSA was
required to make a Change of Control Offer.

  Except as described herein with respect to a Change of Control the indenture
does not contain any other provisions that permit holders of notes to require
that McLeodUSA repurchase or redeem notes in the event of a takeover,
recapitalization or similar restructuring.

Asset Sales

  McLeodUSA will not, and will not permit any Restricted Subsidiary to,
consummate an Asset Sale unless:

  . McLeodUSA or such Restricted Subsidiary, as the case may be, receives
    consideration for such Asset Sale at least equal to the Fair Market
    Value, as evidenced by a Board Resolution delivered to the trustee, of
    the Property or assets sold or otherwise disposed of

  . at least 75% of the consideration received by McLeodUSA or such
    Restricted Subsidiary for such Property or assets consists of

    (a) cash, readily-marketable cash equivalents, or Telecommunications
   Assets

    (b) shares of publicly-traded Voting Stock of any Person engaged in the
   Telecommunications Business in the United States, or

    (c) the assumption of Indebtedness of McLeodUSA or such Restricted
   Subsidiary, other than Indebtedness that is subordinated to the notes, and
   the release of McLeodUSA or the Restricted Subsidiary, as the case may be,
   from all liability on the Indebtedness assumed, and

  . McLeodUSA or such Restricted Subsidiary, as the case may be, uses the Net
    Cash Proceeds from such Asset Sale in the manner set forth in the next
    paragraph.

  Within 360 days after any Asset Sale, McLeodUSA or such Restricted
Subsidiary, as the case may be, may at its option:

  . reinvest an amount equal to the Net Cash Proceeds, or any portion
    thereof, from such Asset Sale in Telecommunications Assets or in Capital
    Stock of any Person engaged in the Telecommunications Business and/or

  . apply an amount equal to such Net Cash Proceeds, or remaining Net Cash
    Proceeds, to the permanent reduction of Indebtedness of McLeodUSA, other
    than Indebtedness to a Restricted Subsidiary, that is senior to or ranks
    equally with the notes or to the permanent reduction of Indebtedness or
    preferred stock of any Restricted Subsidiary, other than Indebtedness to,
    or preferred stock owned by, McLeodUSA or another Restricted Subsidiary.

Any Net Cash Proceeds from any Asset Sale that are not used to reinvest in
Telecommunications Assets or in Capital Stock of any Person engaged in the
Telecommunications Business and/or to reduce senior or equally ranked
Indebtedness of McLeodUSA or Indebtedness or preferred stock of its Restricted
Subsidiaries shall constitute Excess Proceeds.

  If at any time the aggregate amount of Excess Proceeds calculated as of such
date exceeds $25 million, McLeodUSA shall, within 30 days, use such Excess
Proceeds to make an offer to purchase (an "Asset Sale Offer") from all holders
of notes on a pro rata basis with the holders of all other Indebtedness that
ranks equally with the notes and that requires McLeodUSA to make an offer
equivalent to an Asset Sale Offer, notes in an aggregate principal amount equal
to the maximum principal amount that may be purchased out of

                                      S-28
<PAGE>

Excess Proceeds, at a purchase price (the "Asset Sale Purchase Price") in cash
equal to 100% of the principal amount thereof plus accrued and unpaid
interest, if any, to the purchase date, in accordance with the procedures set
forth in the indenture. Upon completion of an Asset Sale Offer, including
payment of the Asset Sale Purchase Price, any surplus Excess Proceeds that
were the subject of such offer shall cease to be Excess Proceeds, and
McLeodUSA may then use such amounts for general corporate purposes.

  McLeodUSA will comply with the requirements of Section 14(e) under the
Securities Exchange Act and any other securities laws or regulations, to the
extent such laws and regulations are applicable, in connection with the
repurchase of notes pursuant to an Asset Sale Offer.

Covenants

  Set forth below are several covenants that are contained in the indenture:

 Limitation on Consolidated Indebtedness

  McLeodUSA will not, and will not permit any Restricted Subsidiary to, Incur
any Indebtedness after the Issue Date unless either:

  A. the ratio of:

    .  the aggregate consolidated principal amount of Indebtedness of
       McLeodUSA outstanding as of the most recent available quarterly or

       since such balance sheet date and the receipt and application of the
       proceeds thereof, to

       Indebtedness for which consolidated financial statements of
       McLeodUSA have been filed with the SEC or have otherwise become
       publicly available, determined on a pro forma basis as if any such
       Indebtedness had been Incurred and the proceeds thereof had been
       applied at the beginning of such four fiscal quarters

    would be less than 5.5 to 1.0 for such four-quarter periods ending

       thereafter, or

  B.  McLeodUSA's Consolidated Capital Ratio as of the most recent quarterly
      or annual balance sheet of McLeodUSA that has been filed with the SEC
      or has otherwise become publicly available, after giving pro forma

    .  the Incurrence of such Indebtedness and any other Indebtedness
       Incurred since such balance sheet date, and

    .  paid-in capital received since such balance sheet date or

         Owned Restricted Subsidiary,

    Indebtedness and such Indebtedness shall be deemed to have been Incurred
    at the time of such transfer or other disposition

  5. Indebtedness Incurred to renew, extend, refinance or refund (each, a

     to clause 3 above in an aggregate principal amount not to exceed the
     aggregate principal amount of and accrued interest on the Indebtedness

     only be permitted under this clause 5 if

    (A)  in the case of any refinancing of the notes or Indebtedness which
         ranks equally to the notes, the refinancing Indebtedness is made
         equal in rank to the notes or constitutes Subordinated
         Indebtedness, and, in the case of any refinancing of Subordinated
         Indebtedness, the refinancing Indebtedness constitutes Subordinated
         Indebtedness, and

    (B)  in any case, the refinancing Indebtedness by its terms, or by the
         terms of any agreement or instrument pursuant to which such
         Indebtedness is issued,

      (x)  does not provide for payments of principal of such Indebtedness

           events or circumstances, but excluding any retirement required
           by virtue of the acceleration of any payment with respect to
           such Indebtedness upon any event of default thereunder, in each
           case prior to the time the same are required by the terms of
           the Indebtedness being refinanced, and

           time the same are required by the terms of the Indebtedness
           being refinanced, other than a

                                     S-30
<PAGE>

         redemption or other retirement at the option of the holder of

Consolidated Indebtedness" covenant, the maximum amount of Indebtedness that
McLeodUSA or a Restricted Subsidiary may Incur pursuant to this "--Covenants--

  (a) such Affiliate Transaction or series of Affiliate Transactions is on

  If any Event of Default (other than an Event of Default specified in clause
(g) or (h) above) occurs and is continuing, then and in every such case, unless
the principal amount of the outstanding notes has become due and payable, the
trustee or the holders of not less than 25% of the outstanding aggregate
principal amount of the notes may declare the principal amount of the notes and
any accrued and unpaid interest on all the notes then outstanding to be
immediately due and payable by a notice in writing to McLeodUSA (and to the
trustee if given by holders of the notes), and upon any such declaration, such
principal amount and any accrued and unpaid interest will become and be
immediately due and payable. If any Event of Default specified in clause (g) or
(h) above occurs, the principal amount of the notes and any accrued and unpaid
interest on the notes then outstanding shall become immediately due and payable
without notice to McLeodUSA and without any declaration or other act on the
part of the trustee or any holder of any notes. In the event of a declaration
of acceleration because an Event of Default set forth in clause (e) above has
occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied, or cured or waived
by the holders of the relevant Indebtedness, within 60 days after such event of
default, provided that no judgment or decree for the payment of money due on
the notes has been obtained by the trustee. Under specified circumstances, the
holders of a majority in principal amount of the outstanding notes by notice to
McLeodUSA and the trustee may rescind an acceleration and its consequences.

  McLeodUSA will be required to deliver to the trustee annually a statement
regarding compliance with the indenture, and McLeodUSA is required within 30
days after becoming aware of any Default or Event of Default, to deliver to the
trustee a statement describing such Default or Event of Default, its status and
what action McLeodUSA is taking or proposes to take with respect thereto. The
trustee may withhold from holders of the notes notice of any continuing Default
or Event of Default, other than relating to the payment of principal or
interest, if the trustee determines that withholding such notice is in the
holders' interest.

Amendment, Supplement and Waiver

  The provisions of the indenture may be amended, supplemented or waived under
the conditions set forth in the accompanying prospectus under "Description of
Debt Securities -- Modification of the Indentures."

Satisfaction and Discharge of the Indenture; Defeasance and Covenant Defeasance

  The provisions of the base indenture regarding (a) satisfaction and discharge
of McLeodUSA's obligations under the indenture and (b) defeasance and covenant
defeasance are described in the accompanying prospectus under "Description of
Debt Securities -- Satisfaction and Discharge of Indentures" and "-- Defeasance
and Covenant Defeasance," respectively. All such provisions of the base
indenture will apply to the notes. In addition, the covenant defeasance
provisions of the base indenture shall, pursuant to the supplemental indenture,
also apply to the provisions described in this prospectus supplement under
"Description of the Notes-- Repurchase at the Option of Holders upon a Change
of Control," " -- Asset Sales," "-- Covenants" and "-- Consolidation, Merger,
Conveyance, Lease or Transfer."


The Trustee

  United States Trust Company of New York is the trustee under the indenture
and its current address is 114 West 47th Street, New York, New York 10036.

  The holders of not less than a majority in principal amount of the
outstanding notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the trustee,
subject to several exceptions. Except during the continuance of an Event of
Default, the trustee will perform only such duties as are specifically set
forth in the indenture. The indenture provides that in case an Event of Default
shall occur (which shall not be cured or waived), the trustee will be required,
in the exercise of its rights and powers under the indenture, to use the degree
of care of a prudent person in the conduct of such person's own affairs.
Subject to such provisions, the trustee will be under no obligation to exercise
any of its rights or powers under the indenture at the request of any of the
holders of the notes, unless such holders shall have offered to the trustee
indemnity satisfactory to it against any loss, liability or expense.

No Personal Liability of Controlling Persons, Directors, Officers, Employees
and Stockholders

  No controlling Person, director, officer, employee, incorporator or
stockholder of McLeodUSA, as such, shall have any liability for any covenant,
agreement or other obligations of McLeodUSA under the notes or the indenture or
for any claim based on, in respect of, or by reason of, such obligations or
their creation, solely by reason of its past, present or future status as a
controlling Person, director, officer, employee, incorporator or stockholder of
McLeodUSA. By accepting a note each holder waives and releases all such
liability (but only such liability). The waiver and release are part of the
consideration for issuance of the notes. Nonetheless, such waiver may not be
effective to waive liabilities under the federal securities laws and it has
been the view of the SEC that such a waiver is against public policy.

Transfer and Exchange

  The outstanding notes are subject to various restrictions on transfer. A
holder may transfer or exchange notes in accordance with the indenture.
McLeodUSA, the Security Registrar and the trustee may require a holder, among
other things, to furnish appropriate endorsements and transfer documents and
McLeodUSA may require a holder to pay any taxes and fees required by law or
permitted by the indenture.

contingent obligations, the maximum liability upon the occurrence of the
contingency giving rise to the obligation; provided that the amount outstanding
at any time of any Indebtedness issued with original issue discount (including,
without limitation, our 10 1/2% senior discount notes) is the face amount of
such Indebtedness less the remaining unamortized portion of the original issue

  The indentures governing our 10 1/2% senior discount notes, 9 1/4% senior
notes, 8 3/8% senior notes, 9 1/2% senior notes and 8 1/8% senior notes impose
operating and financial restrictions on us and our subsidiaries that are
substantially the same as the restrictions governing the notes. These
restrictions affect, and in some cases significantly limit or prohibit, among
other things, our ability and the ability of our subsidiaries to incur
additional indebtedness, pay dividends or make distributions in respect of our
or such subsidiaries' capital stock, make other restricted payments, enter into
sale and leaseback transactions, create liens upon assets, enter into
transactions with affiliates or related persons, sell assets, or consolidate,
merge or sell all or substantially

all of our, or our subsidiaries' assets. There can be no assurance that such
covenants will not adversely affect our ability to finance our future
operations or capital needs or to engage in other business activities that may
be in our interest.

  We have received a non-binding commitment from The Chase Manhattan Bank to
lead a syndication to provide a proposed revolving credit facility to a newly
formed, wholly owned subsidiary of McLeodUSA (the "Borrower"). The proposed
revolving credit facility would be guaranteed by us and all of our subsidiaries
and would be secured by a first priority lien on all our, our subsidiaries' and
the Borrower's current and future assets and properties and by a first priority
pledge of the stock of the Borrower and our other subsidiaries. One of the
covenants in the proposed revolving credit facility would restrict our ability
to prepay, redeem or purchase debt and one of the events of default would be
the occurrence of a default by us or the Borrower with respect to other
indebtedness. The Borrower would be obligated to pay interest and fees with
respect to the proposed revolving credit facility at the rates and in the
amounts specified in such commitment. We expect that revisions will be made to
such commitment and that additional matters will be negotiated with the
prospective lenders prior to the finalization of the proposed revolving credit
facility. We cannot assure you that we will complete the proposed revolving
credit facility on acceptable terms or at all.

dated the date hereof, each underwriter has severally agreed to purchase from

underwriting agreement.

</TABLE>

  In the underwriting agreement, the underwriters have severally agreed,
subject to the terms and conditions set forth therein, to purchase all of the
principal amount offered hereby (other than those subject to the over-allotment
option described below), if any such notes are purchased. In the event of a
default by any underwriter, the underwriting agreement provides that, in
certain circumstances, the purchase commitments of the non-defaulting
underwriters may be increased or the underwriting agreement may be terminated.

  The underwriters, for whom Salomon Smith Barney Inc., Credit Suisse First
Boston Corporation and Lehman Brothers Inc. are acting as representatives,
propose initially to offer the notes to the public at the public offering price
set forth on the cover page of this prospectus, and to some dealers at such
price less a concession not in excess of $   per note. The underwriters may
allow, and such dealers may reallow, a concession not in excess of $   per note
to other dealers. After the public offering, the public offering price and such
concessions may be changed.

  In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell the notes in the open market. These
transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of the notes
in excess of the principal amount to be purchased by the underwriters in the
offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of our notes in the open market after the
distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of bids or purchases of our notes made for the
purpose of preventing or retarding a decline in the market price of our notes
while the offering is in progress.

  The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when the
underwriters, in covering syndicate short positions or making stabilizing
purchases, repurchase shares originally sold by that syndicate member.

  Any of these activities may cause the price of our notes to be higher than
the price that otherwise would exist in the open market in the absence of such
transactions. These transactions may be effected on the open market, or
otherwise and, if commenced, may be discontinued at any time.

  Salomon Smith Barney Inc. and Credit Suisse First Boston Corporation have
performed investment banking and advisory services for us from time to time for
which they have received customary fees and expenses. They may, from time to
time, engage in transactions with and perform services for us in the ordinary
course of their business.

  The underwriting agreement provides that we will indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act, or
contribute to payments the underwriters may be required to make in respect of
such liabilities.

  We have agreed with the underwriters not to offer, sell or contract to sell,
or otherwise dispose of, directly or indirectly, or announce the offering of,
any debt securities issued or guaranteed by us for a period of 90 days from the
date of this prospectus supplement without the prior written consent of Salomon
Smith Barney Inc.

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

  This prospectus and the information incorporated by reference in it include
"forward-looking statements" within the meaning of Section 27A of the
Securities Act and Section 21E of the Securities Exchange Act. We intend the
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements in these sections. All statements regarding our
expected financial position and operating results, our business strategy, our
financing plans, our future capital requirements, forecasted demographic and
economic trends relating to our industry, our ability to complete acquisitions,
to realize anticipated cost savings and other benefits from acquisitions and to
recover acquisition-related costs, and similar matters are forward-looking
statements. These statements are subject to known and unknown risks,
uncertainties and other factors that could cause our actual results to differ
materially from the statements. The forward-looking information is based on
various factors and was derived using numerous assumptions. In some cases, you
can identify these statements by our use of forward-looking words such as
"may," "will," "should," "anticipate," "estimate," "expect," "plan," "believe,"
"predict," "potential" or "intend." You should be aware that these statements
only reflect our predictions. Actual events or results may differ
substantially. Important factors that could cause our actual results to be
materially different from our expectations include those discussed in the
applicable prospectus supplement under the caption "Risk Factors." We undertake
no obligation to update or revise publicly any forward-looking statements,
whether as a result of new information, future events or otherwise.

                                  Our Company

  We provide communications services to business and residential customers in
the Midwestern and Rocky Mountain regions of the United States. We offer local,
long distance, Internet access, data, voice mail and paging services, from a
single company on a single bill. We believe we are the first company in many of
our markets to offer one-stop shopping for communications services tailored to
customers' specific needs.

  Our approach makes it easier for both our business and our residential
customers to satisfy their communications needs. It also allows businesses to
receive customized services, such as competitive long distance pricing and
enhanced calling features, that might not otherwise be directly available on a
cost-effective basis.

  In addition to our core business of providing competitive local, long
distance and related communications services, we also derive revenue from:

  . sale of advertising space in telephone directories

  . traditional local telephone company services in east central Illinois and
    southeast South Dakota

  . special access, private line and data services

  . communications network maintenance services

  . telephone equipment sales, leasing, service and installation

  . video services

  . telemarketing services

  . computer networking services

  . other communications services, including cellular, operator, payphone,
    mobile radio, paging services and Web site development and hosting

  In most of our markets, we compete with the existing local phone company by
leasing its lines and switches. In other markets, primarily in east central

                              COVERAGE RATIOS

  For each of the years ended December 31, 1994, 1995, 1996, 1997 and 1998,
earnings were insufficient to cover fixed charges by $11.4 million, $11.4
million, $22.6 million, $84.4 million and $135.5 million, respectively. For the
three months ended March 31, 1998 and 1999, earnings were insufficient to cover
fixed charges by $32.0 million and $51.7 million, respectively. For the purpose
of calculating the ratio of earnings to fixed charges, earnings consist of net
loss before income taxes plus fixed charges (excluding capitalized interest).
Fixed charges consist of interest on all debt (including capitalized interest),
amortization of debt discount and deferred loan costs and the portion of rental
expense that is representative of the interest component of rental expense
(deemed to be one-third of rental expense which management believes is a
reasonable approximation of the interest component). Because we did not have
any preferred stock outstanding during any of these periods, the ratio of
earnings to fixed charges and preferred stock dividends is the same as the
ratio of earnings to fixed charges.

                                USE OF PROCEEDS

  Unless we specify otherwise in the applicable prospectus supplement, we will
use the net proceeds from the sale of the offered securities for general
corporate purposes, including working capital, the repayment or refinancing of
our indebtedness, future acquisitions and/or capital expenditures. Until we
apply the net proceeds for specific purposes, we may invest such net proceeds
in short-term or marketable securities.

                          DESCRIPTION OF COMMON STOCK

  The following summary description of our capital stock is based on the
provisions of our certificate of incorporation and bylaws and the applicable
provisions of the Delaware General Corporation Law. For information on how to
obtain copies of our certificate of incorporation and bylaws, see "Where You
Can Find More Information."

General

  Under our certificate of incorporation, we have authority to issue
274,000,000 shares of capital stock, consisting of 250,000,000 shares of Class
A common stock, 22,000,000 shares of Class B common stock and 2,000,000 shares
of preferred stock. We have declared a two-for-one stock split to be effected
in the form of a stock dividend for our Class A common stock. The record date
for the stock split was July 12, 1999 and distribution of the additional shares
will take place on July 26, 1999. Giving effect to this stock split, we had
issued and outstanding as of July 1, 1999, 150,417,738 shares of our Class A
common stock, no shares of our Class B common stock and no shares of our
preferred stock.

  The rights of the holders of our Class A common stock and our Class B common
stock discussed below are subject to such rights as our board of directors may
from time to time confer on holders of our preferred stock that may be issued
in the future. Such rights may adversely affect the rights of holders of our
Class A common stock or our Class B common stock, or both.

Class A Common Stock

  Voting Rights. Each holder of our Class A common stock is entitled to attend
all special and annual meetings of our stockholders and, together with the
holders of all other classes of stock entitled to vote at such meetings, to
vote upon any matter, including, without limitation, the election of directors.
Holders of our Class A common stock are entitled to one vote per share.

  Liquidation Rights. In the event of any dissolution, liquidation or winding
up of McLeodUSA, whether voluntary or involuntary, the holders of our Class A
common stock, the holders of our Class B common stock and the holders of any
class or series of stock entitled to participate with our Class A and Class B
common stock, will become entitled to participate in the distribution of any of
our assets remaining after we have paid, or provided for payment of, all of our
debts and liabilities and after we have paid, or set aside for payment, to the
holders of any class of stock having preference over our Class A common stock
in the event of dissolution, liquidation or winding up, the full preferential
amounts, if any, to which they are entitled.

  Dividends. Dividends may be paid on our Class A common stock, our Class B
common stock and on any class or series of stock entitled to participate with
our Class A and Class B common stock when and as declared by our board of
directors. We have never paid, however, any cash dividends and the indentures
governing our outstanding debt securities prohibit us from paying cash
dividends.

  No Preemptive or Conversion Rights. The holders of our Class A common stock
have no preemptive or subscription rights to purchase additional securities
issued by us nor any rights to convert their Class A common stock into other of
our securities or to have their shares redeemed by us.

Class B Common Stock

  Voting Rights. Each holder of our Class B common stock is entitled to attend
all special and annual meetings of our stockholders and, together with the
holders of all other classes of stock entitled to vote at such meetings, to
vote upon any matter or thing, including, without limitation, the election of
directors. Holders of our Class B common stock are entitled to .40 vote per
share.

  Liquidation Rights. In the event of any dissolution, liquidation or winding
up of McLeodUSA, whether voluntary or involuntary, the holders of our Class B
common stock, the holders of our Class A common stock

                                       5
<PAGE>

and the holders of any class or series of stock entitled to participate with
our Class B and Class A common stock, will become entitled to participate in
the distribution of any of our assets remaining after we have paid, or provided
for payment of, all of our debts and liabilities and after we have paid, or set
aside for payment, to the holders of any class of stock having preference over
our Class B common stock in the event of dissolution, liquidation or winding up
the full preferential amounts, if any, to which they are entitled.

  Dividends. Dividends may be paid on our Class B common stock, our Class A
common stock and on any class or series of stock entitled to participate with
our Class B and Class A common stock when and as declared by our board of
directors.

  Conversion into Our Class A Common Stock; No Other Preemptive or Conversion
Rights. The shares of our Class B common stock may be converted at any time at
the option of the holder into fully paid and nonassessable shares of our Class
A common stock at the rate of one share of our Class A common stock for each
share of Class B common stock, as adjusted for any stock split. Except for this
conversion right, the holders of our Class B common stock have no preemptive or
subscription rights to purchase additional securities issued by us nor any
rights to convert their Class B common stock into other of our securities or to
have their shares redeemed by us.

Certain Charter and Statutory Provisions

  Classified Board. Our certificate of incorporation provides for the division
of our board of directors into three classes of directors, serving staggered
three-year terms. Our certificate of incorporation further provides that the
approval of the holders of at least two-thirds of the shares entitled to vote
thereon and the approval of a majority of our entire board of directors are
necessary for the alteration, amendment or repeal of certain sections of our
certificate of incorporation relating to the election and classification of our
board of directors, limitation of director liability, indemnification and the
vote requirements for such amendments to our certificate of incorporation.
These provisions may have the effect of deterring hostile takeovers or delaying
changes in control or management of our company.

  Certain Statutory Provisions. We are subject to the provisions of Section 203
of the Delaware General Corporation Law. In general, this statute prohibits a
publicly held Delaware corporation like us from engaging in a business
combination with an interested stockholder for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless

  . before such date, the corporation's board of directors approved either
    the business combination or the transaction that resulted in the
    stockholder becoming an interested stockholder,

  . upon consummation of the transaction that resulted in such person
    becoming an interested stockholder, the interested stockholder owned at
    least 85% of the voting stock of the corporation outstanding at the time
    the transaction commenced, excluding, for purposes of determining the
    number of shares outstanding, shares owned by certain directors or
    certain employee stock plans, or

  . on or after the date the stockholder became an interested stockholder,
    the business combination is approved by the corporation's board of
    directors and authorized by the affirmative vote, and not by written
    consent, of at least two-thirds of the outstanding voting stock of the
    corporation excluding that stock owned by the interested stockholder.

  A "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder. An "interested
stockholder" is a person, other than the corporation and any direct or indirect
wholly owned subsidiary of the corporation, who together with affiliates and
associates, owns or, as an affiliate or associate, within three years prior,
did own 15% or more of the corporation's outstanding voting stock.

  Section 203 expressly exempts from the requirements described above any
business combination by a corporation with an interested stockholder who became
an interested stockholder at a time when the section did not apply to the
corporation. As permitted by the Delaware General Corporation Law, our original
certificate of incorporation provided that it would not be governed by Section
203. Several of our stockholders, including

                                       6
<PAGE>

Clark E. and Mary E. McLeod and Interstate Energy Corporation became interested
stockholders within the meaning of Section 203 while that certificate of
incorporation was in effect. Accordingly, future transactions between us and
any of these stockholders will not be subject to the requirements of Section
203.

  Our certificate of incorporation empowers our board of directors to redeem
any of our outstanding capital stock at a price determined by our board of
directors, which price will be at least equal to the lesser of

  .  fair market value, as determined in accordance with our certificate of
     incorporation, or

  .  in the case of a "Disqualified Holder," such holder's purchase price, if
     the stock was purchased within one year of such redemption,

to the extent necessary to prevent the loss or secure the reinstatement of any
license, operating authority or franchise from any governmental agency. A
"Disqualified Holder" is any holder of shares of our capital stock whose
holding of such stock may result in the loss of, or failure to secure the
reinstatement of, any license or franchise from any governmental agency held by
us or any of our subsidiaries to conduct any portion of our business or the
business of any of our subsidiaries. Under the Telecommunications Act of 1996,
non-U.S. citizens or their representatives, foreign governments or their
representatives, or corporations organized under the laws of a foreign country
may not own, in the aggregate, more than 20% of a common carrier licensee or
more than 25% of the parent of a common carrier licensee if the Federal
Communications Commission, or FCC, determines that the public interest would be
served by prohibiting such ownership. Additionally, the FCC's rules may under
some conditions limit the size of investments by foreign telecommunications
carriers in U.S. international carriers.

Limitation of Liability and Indemnification

  Limitations of Director Liability. Section 102(b)(7) of the Delaware General
Corporation Law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. Although Section
102(b)(7) does not change directors' duty of care, it enables corporations to
limit available relief to equitable remedies such as injunction or rescission.
Our certificate of incorporation limits the liability of our directors to us or
our stockholders to the full extent permitted by Section 102(b)(7).
Specifically, our directors are not personally liable for monetary damages to
us or our stockholders for breach of the director's fiduciary duty as a
director, except for liability for:

  .any breach of the director's duty of loyalty to us or our stockholders

  . acts or omissions not in good faith or that involve intentional
    misconduct or a knowing violation of law

  . unlawful payments of dividends or unlawful stock repurchases or
    redemptions as provided in Section 174 of the Delaware General
    Corporation Law

  . any transaction from which the director derived an improper personal
    benefit

  Indemnification. To the maximum extent permitted by law, our bylaws provide
for mandatory indemnification of our directors and officers against any
expense, liability or loss to which they may become subject, or which they may
incur as a result of being or having been a director or officer of McLeodUSA.
In addition, we must advance or reimburse directors and officers for expenses
incurred by them in connection with indemnifiable claims. We also maintain
directors' and officers' liability insurance.

Transfer Agent and Registrar

  The transfer agent and registrar for our Class A common stock is Norwest Bank
Minnesota, N.A.

Stockholders' Agreements

  On November 18, 1998, we entered into a stockholders' agreement (the
"Stockholders' Agreement") with several of our significant stockholders
consisting of IES Investments Inc. (a subsidiary of Interstate Energy), Clark
E. and Mary E. McLeod, and Richard A. and Gail G. Lumpkin and several other
parties related to the Lumpkins.

                                       7
<PAGE>

  The Stockholders' Agreement provides, among other things, that:

  . until December 31, 2001, the parties will not sell any of our equity
    securities without receiving the prior written consent of our board of
    directors, except for transfers specifically permitted by the
    Stockholders' Agreement

  . our board of directors will determine on a quarterly basis starting with
    the quarter ending December 31, 1998 and ending on December 31, 2001, the
    aggregate number, if any, of shares of our Class A common stock, not to
    exceed in the aggregate 150,000 shares per quarter, that the parties may
    sell during designated trading periods following the release of our
    quarterly or annual financial results

  . to the extent our board of directors grants registration rights to a
    party to the agreement in connection with a sale of our securities by
    such party, it will grant similar registration rights to the other
    parties

  . our board of directors will determine on an annual basis commencing with
    the year ending December 31, 1999 and ending on December 31, 2001 (each
    such year, an "Annual Period"), the aggregate number, if any, of shares
    of our Class A common stock, not to exceed in the aggregate on an annual
    basis a number of shares equal to 15% of the total number of shares of
    Class A common stock beneficially owned by the parties as of December 31,
    1998 (the "Registrable Amount"), to be registered by us under the
    Securities Act for sale by the parties

  . in any underwritten offering of shares of Class A common stock by us,
    other than an offering on a registration statement on Form S-4 or Form S-
    8 or any other form which would not permit the inclusion of shares of our
    Class A common stock owned by the parties, we will undertake to register
    the shares of our Class A common stock of such parties up to the
    Registrable Amount, if any, as determined by our board of directors

  . we may subsequently determine not to register any shares of the parties
    under the Securities Act and may either not file a registration statement
    or otherwise withdraw or abandon a registration statement previously
    filed

  The Stockholders' Agreement terminates on December 31, 2001. If during any
Annual Period we have not provided a party a reasonable opportunity to sell an
aggregate number of shares of Class A common stock equal to not less than 15%
of the total number of shares of Class A common stock beneficially owned by
such party as of December 31, 1998, then such party may terminate the
Stockholders' Agreement as it applies to such party.

  Under the Stockholders' Agreement, each party also agreed, until such party
owns less than 4 million shares of Class A common stock or until December 31,
2001, whichever occurs first, to vote such party's shares and take all action
within its power to:

  . establish the size of our board of directors at up to 11 directors

  . cause to be elected to our board of directors one director designated by
    Interstate Energy for so long as IES Investments owns at least 4 million
    shares of Class A common stock

    executive officers of McLeodUSA designated by Clark McLeod for so long as
    Clark and Mary McLeod collectively own at least 4 million shares of Class
    A common stock

    as the former stockholders of Consolidated Communications, Inc. who are a
    party to the agreement collectively own at least 4 million shares of
    Class A common stock

  . cause to be elected to our board of directors up to six non-employee
    directors nominated by our board

<PAGE>

  On January 7, 1999, in connection with the Ovation acquisition, M/C Investors
L.L.C. and Media/Communications Partners III Limited Partnership (collectively,
"M/C") entered into a separate stockholders' agreement (the "Ovation
Stockholders' Agreement") with the parties to the Stockholders' Agreement.

  The Ovation Stockholders' Agreement provides that, until December 31, 2001,
M/C will not sell any of our equity securities without receiving the prior
written consent of our board of directors. The Ovation Stockholders' Agreement
also contains various provisions intended to insure that M/C is treated on a
basis similar to the parties to the Stockholders' Agreement in connection with
permitted sales of our securities under the Stockholders' Agreement generally
starting December 31, 1999. In addition, for so long as M/C owns at least 2.5
million shares of our Class A common stock, M/C has agreed to vote its shares
in accordance with the voting agreement contained in the Stockholders'
Agreement and the other partries have agreed to vote their shares to cause to
be elected to our board of directors one director designated by M/C.

  The Ovation Stockholders' Agreement terminates on December 31, 2001. In
addition, if (1) during each of the years ending December 31, 2000 and December
31, 2001, we have not provided M/C a reasonable opportunity to register under
the Securities Act for sale an aggregate number of shares of our Class A common
stock equal to not less than 15% of the total number of shares of Class A
common stock beneficially owned by M/C as of March 31, 1999, or (2) after
January 1, 2000, the Stockholders' Agreement has been terminated by all parties
to such agreement, then M/C may terminate the Ovation Stockholders' Agreement.
The Ovation Stockholders' Agreement will be terminated with respect to all
parties other than M/C and us at such time as the Stockholders' Agreement is
terminated.

                         DESCRIPTION OF PREFERRED STOCK

  The following description is a general summary of the terms of the preferred
stock which we may issue. The description below and in any prospectus
supplement does not purport to be complete and is subject to and qualified in
its entirety by reference to our certificate of incorporation, the applicable
certificate of designations to our certificate of incorporation which will
determine the terms of the related series of preferred stock and our bylaws,
each of which will be made available upon request.

General

  Our certificate of incorporation authorizes our board of directors, from time
to time and without further stockholder action, to provide for the issuance of
up to 2,000,000 shares of preferred stock, par value $.01 per share, in one or
more series, and to fix the relative rights and preferences of the shares,
including voting powers, dividend rights, liquidation preferences, redemption
rights and conversion privileges. As of the date of this prospectus, no shares
of preferred stock are outstanding. As a result of its broad discretion with
respect to the creation and issuance of preferred stock without stockholder
approval, the board of directors could adversely affect the voting power of the
holders of our Class A common stock and Class B common stock and, by issuing
shares of preferred stock with certain voting, conversion and/or redemption
rights, may discourage any attempt to obtain control of us.

  The rights, preferences, privileges and restrictions of the preferred stock
of each series will be fixed by the certificate of designations relating to
such issues. You should refer to the prospectus supplement relating to the
class or series of preferred stock being offered for the specific terms of that
class or series, including:

  (1)  the title and stated value of the preferred stock being offered

  (2)  the number of shares of preferred stock being offered, their
       liquidation preference per share, if any, and their purchase price

       calculating the payment date(s) applicable to the preferred stock
       being offered

       cumulative, the date from which dividends on the preferred stock being
       offered shall accumulate

       preferred stock being offered

  (6)  the provisions for a sinking fund, if any, for the preferred stock
       being offered

  (7)  the provisions for redemption, if applicable, of the preferred stock
      being offered

  (8)  any listing of the preferred stock being offered on any securities
       exchange or market

  (9)  the terms and conditions, if applicable, upon which the preferred
       stock being offered will be convertible into, or exchangeable for, our
       Class A common stock or debt securities, including the conversion or
       exchange price, or the manner of calculating the price, and the
       conversion or exchange period

  (10)  voting rights, if any, of the preferred stock being offered

  (11)  whether interests in the preferred stock being offered will be
        represented by depositary shares

  (12)  a discussion of any material and/or special United States federal
        income tax considerations applicable to the preferred stock being
        offered

                                       10
<PAGE>

  (13)  the relative ranking and preferences of the preferred stock being
        offered as to dividend rights and rights upon liquidation,
        dissolution or winding up of our affairs

  (14)  any limitations on the issuance of any class or series of preferred
        stock ranking senior to or on a parity with the series of preferred
        stock being offered as to dividend rights and rights upon
        liquidation, dissolution or winding up of our affairs

  (15)  any other specific terms, preferences, rights, limitations or
        restrictions of the preferred stock being offered

Rank

  Unless otherwise specified in the applicable prospectus supplement, the
preferred stock will, with respect to distribution rights and rights upon
liquidation, dissolution or winding up of McLeodUSA, rank:

  (1)  senior to all of our classes or series of common stock and to all
       equity securities the terms of which specifically provide that such
       equity securities rank junior to the preferred stock being offered

  (2)  on a parity with all equity securities we have issued, other than
       those referred to in clauses (1) and (3) of this subheading

  (3)  junior to all equity securities we have issued, the terms of which
       specifically provide that such equity securities rank senior to the
       preferred stock being offered

For purposes of this description, the term "equity securities" does not include
convertible debt securities.

Distributions

  Holders of the preferred stock of each series will be entitled to receive,
when, as and if declared by our board of directors, out of our assets legally
available for payment to stockholders, cash distributions, or distributions in
kind or in other property if expressly permitted and described in the
applicable prospectus supplement, at such rates and on such dates as will be
set forth in the applicable prospectus supplement. Each such distribution shall
be payable to holders of record as they appear on our stock transfer books on
such record dates as shall be fixed by our board of directors. Distributions on
any series of preferred stock, if cumulative, will be cumulative from and after
the date set forth in the applicable prospectus supplement.

Redemption

  The terms and conditions, if any, upon which the preferred stock will be
subject to mandatory redemption or redemption at our option, either in whole or
in part, will be described in the applicable prospectus supplement.

Liquidation Preference

  Upon any voluntary or involuntary liquidation, dissolution or winding up of
our affairs, then, before any distribution or payment shall be made to the
holders of any Class A common stock or Class B common stock or any other class
or series of shares of our capital stock ranking junior to the preferred stock
in the distribution of assets upon any liquidation, dissolution or winding up
of our company, the holders of each series of preferred stock shall be entitled
to receive out of our assets legally available for distribution to stockholders
liquidating distributions in the amount of the liquidation preference set forth
in the applicable prospectus supplement, plus an amount equal to all
accumulated and unpaid distributions. After payment of the full amount of the
liquidating distributions to which they are entitled, the holders of shares of
preferred stock will have no right or claim to any of our remaining assets. If,
upon any such voluntary or involuntary liquidation, dissolution or winding up,
our available assets are insufficient to pay the amount of the liquidating
distributions on all outstanding shares of preferred stock and the
corresponding amounts payable on all shares of other classes or series of our
shares of capital stock ranking on a parity with the preferred stock in the
distribution of assets, then the holders of the preferred stock and all other
such classes or series of shares of capital stock shall share ratably in any
such distribution of assets in proportion to the full liquidating distributions
to which they would otherwise be respectively entitled.

                                       11
<PAGE>

  If liquidating distributions shall have been made in full to all holders of
preferred stock, our remaining assets shall be distributed among the holders of
any other classes or series of shares of capital stock ranking junior to the
preferred stock upon liquidation, dissolution or winding up, according to their
respective rights and preferences and in each case according to their
respective number of shares. For such purposes, our consolidation or merger
with or into any other corporation, trust or entity, or the sale, lease or
conveyance of all or substantially all of our property or business, shall not
be deemed to constitute a liquidation, dissolution or winding up of our
company.

Voting Rights

  Holders of preferred stock will have the voting rights as indicated in the
applicable prospectus supplement.

Conversion Rights

  The terms and conditions, if any, upon which any series of preferred stock is
convertible into Class A common stock will be set forth in the applicable
prospectus supplement relating thereto. Such terms will include the number of
shares of Class A common stock into which the shares of preferred stock are
convertible, the conversion price or the manner of calculating the conversion
price, the conversion date(s) or period(s), provisions as to whether conversion

stock.

                        DESCRIPTION OF DEPOSITARY SHARES

  The following description is a general summary of the terms of the depositary
shares which we may issue. This summary does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, all of the
provisions of the applicable Deposit Agreement and related depositary receipts.

General

  We may issue depositary receipts for depositary shares, each of which will
represent a fractional interest of a share of a particular series of preferred
stock, as specified in the applicable prospectus supplement. Shares of
preferred stock of each series represented by depositary shares will be
deposited under a separate Deposit Agreement between the "depositary" named in
the Deposit Agreement and us. Subject to the terms of the Deposit Agreement,
each owner of a depositary receipt will be entitled, in proportion to the
fractional interest of a share of a particular series of preferred stock
represented by the depositary shares evidenced by that depositary receipt, to
all the rights and preferences of the preferred stock represented by those
depositary shares, including dividend, voting, conversion, redemption and
liquidation rights.

  The depositary shares will be evidenced by depositary receipts issued
pursuant to the applicable Deposit Agreement. Immediately following the
issuance and delivery of our preferred stock to the depositary, we will cause
the depositary to issue, on our behalf, the depositary receipts. Copies of the
applicable form of Deposit Agreement and depositary receipt may be obtained
from us upon request, and the statements made in this summary relating to the
Deposit Agreement and the depositary receipts to be issued under the Deposit
Agreement are summaries of provisions of the Deposit Agreement and the related
depositary receipts.

Dividends and Other Distributions

  The depositary will distribute all cash dividends or other cash distributions
received in respect of the preferred stock to the record holders of depositary
receipts evidencing the related depositary shares in proportion to the number
of such depositary receipts owned by such holders, subject to the obligations
of holders to file proofs, certificates and other information and to pay some
charges and expenses to the depositary.

  In the event of a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary receipts
entitled to that property, subject to the obligations of holders to file
proofs, certificates and other information and to pay some charges and expenses
to the depositary, unless the depositary determines that it is not feasible to
make the distribution, in which case the depositary may, with our approval,
sell the property and distribute the net proceeds from the sale to the holders.

  No distribution will be made in respect of any depositary share to the extent
that it represents any preferred stock converted into other securities.

Withdrawal of Preferred Stock

  Upon surrender of the depositary receipts at the corporate trust office of
the depositary, unless the related depositary shares have previously been
called for redemption or converted into other securities, the holders of those
depositary receipts will be entitled to delivery at the corporate trust office,
to or upon the holder's order, of the number of whole or fractional shares of
the preferred stock and any money or other property represented by the
depositary shares evidenced by the depositary receipts. Holders of depositary
receipts will be entitled to receive whole or fractional shares of the related
preferred stock on the basis of the proportion of preferred stock represented
by the depositary share as specified in the applicable prospectus supplement,
but holders of the shares of preferred stock will not thereafter be entitled to
receive depositary shares therefor. If the depositary receipts delivered by the
holder evidence a number of depositary shares in excess of the number of
depositary shares representing the number of shares of preferred stock to be
withdrawn, the depositary will deliver to the holder at the same time a new
depositary receipt evidencing the excess number of depositary shares.

Redemption of Depositary Shares

  Whenever we redeem shares of preferred stock held by the depositary, the
depositary will redeem, as of the same redemption date, the number of
depositary shares representing shares of the preferred stock so redeemed,
provided we have paid in full to the depositary the redemption price of the
preferred stock to be redeemed plus an amount equal to any accrued and unpaid
dividends thereon to the date fixed for redemption. The redemption price per
depositary share will be equal to the corresponding proportion of the
redemption price and any other amounts per share payable with respect to the
preferred stock. If fewer than all the depositary shares are to be redeemed,
the depositary shares to be redeemed will be selected pro rata, as nearly as
may be practicable without creating fractional depositary shares, or by another
equitable method.

  From and after the date fixed for redemption, all dividends in respect of the
shares of preferred stock called for redemption will cease to accrue, the
depositary shares called for redemption will no longer be deemed to be
outstanding and all rights of the holders of the depositary receipts evidencing
the depositary shares called for redemption will cease, except the right to
receive any moneys payable upon the redemption and any money or other property
to which the holders of the depositary receipts were entitled upon the
redemption and surrender thereof to the depositary.

Voting of the Preferred Stock

  Upon receipt of notice of any meeting at which the holders of the preferred
stock are entitled to vote, the depositary will mail the information contained
in the notice of meeting to the record holders of the depositary receipts
evidencing the depositary shares which represent such preferred stock. Each
record holder of depositary receipts evidencing depositary shares on the record
date, which will be the same date as the record date for the preferred stock,
will be entitled to instruct the depositary as to the exercise of the voting
rights pertaining to the amount of preferred stock represented by the holder's
depositary shares. The depositary will vote the amount of preferred stock
represented by the depositary shares in accordance with the instructions, and
we will agree to take all reasonable action which may be deemed necessary by
the depositary in order to enable the depositary to do so. The depositary will
abstain from voting the amount of preferred stock represented by the depositary
shares to the extent it does not receive specific instructions from the holders
of depositary receipts evidencing the depositary shares. The depositary shall
not be responsible for any failure to carry out any instruction to vote, or for
the manner or effect of any such vote made, as long as such action or non-
action is in good faith and does not result from negligence or willful
misconduct of the depositary.

Liquidation Preference

  In the event of our liquidation, dissolution or winding up, whether voluntary
or involuntary, the holders of each depositary receipt will be entitled to the
fraction of the liquidation preference accorded each share of preferred stock
represented by the depositary shares evidenced by such depositary receipt, as
set forth in the applicable prospectus supplement.

Conversion of Preferred Stock

  The depositary shares, as such, are not convertible into our common stock or
any of our other securities or property. Nevertheless, if specified in the
applicable prospectus supplement relating to an offering of depositary shares,
the depositary receipts may be surrendered by their holders to the depositary
with written instructions to the depositary to instruct us to cause conversion
of the preferred stock represented by the depositary shares evidenced by the
depositary receipts into whole shares of our Class A common stock, other shares
of our preferred stock or other of our equity or debt securities, and we have
agreed that upon receipt of those instructions and any amounts payable in
respect thereof, we will cause the conversion thereof utilizing the same
procedures as those provided for delivery of preferred stock to effect such
conversion. If the depositary shares evidenced by a depositary receipt are to
be converted in part only, a new depositary receipt or receipts will be issued
for any depositary shares not to be converted. No fractional shares of Class A
common stock will be issued upon conversion, and if such conversion would
result in a fractional share being issued, we will pay an amount in cash equal
to the value of the fractional interest based upon the average of the closing
prices of the Class A common stock for a specified period of time prior to the
conversion.

Amendment and Termination of the Deposit Agreement

  The form of depositary receipt evidencing the depositary shares which
represent the preferred stock and any provision of the Deposit Agreement may
at any time be amended by agreement between the depositary and us. However,
any amendment that materially and adversely alters the rights of the holders
of depositary receipts or that would be materially and adversely inconsistent
with the rights granted to the holders of the related preferred stock will not
be effective unless such amendment has been approved by the existing holders
of at least a majority of the depositary shares evidenced by the depositary
receipts then outstanding. No amendment shall impair the right, subject to
certain exceptions in the Deposit Agreement, of any holder of depositary
receipts to surrender any depositary receipt with instructions to deliver to
the holder the related preferred stock and all money and other property, if
any, represented thereby, except in order to comply with law. Every holder of
an outstanding depositary receipt at the time any such amendment becomes
effective shall be deemed, by continuing to hold such receipt, to consent and
agree to such amendment and to be bound by the Deposit Agreement as amended
thereby.

  Unless specified otherwise in the applicable prospectus supplement, we may
terminate the Deposit Agreement upon not less than 30 days prior written
notice to the depositary if a majority of each class of depositary shares
affected by such termination consents, whereupon the depositary shall deliver
or make available to each holder of depositary receipts, upon surrender of the
depositary receipts held by such holder, such number of whole or fractional
shares of preferred stock as are represented by the depositary shares
evidenced by such depositary receipts together with any other property held by
the depositary with respect to such depositary receipt. In addition, the
Deposit Agreement will automatically terminate if:

  (1)  all outstanding depositary shares shall have been redeemed

  (2)  there shall have been a final distribution in respect of the related
       preferred stock in connection with any liquidation, dissolution or
       winding up of our company and such distribution shall have been
       distributed to the holders of depositary receipts evidencing the
       depositary shares representing such preferred stock

  (3)  each share of the related preferred stock shall have been converted
       into our securities not represented by depositary shares

Charges of Preferred Stock Depositary

  We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the Deposit Agreement. In addition, we will pay
the fees and expenses of the depositary in connection with the performance of
its duties under the Deposit Agreement. However, holders of depositary
receipts will pay the fees and expenses of the depositary for any duties
requested by such holders to be performed which are outside of those expressly
provided for in the Deposit Agreement.


Miscellaneous

  The depositary will forward to holders of depositary receipts any reports
and communications from us which are received by the depositary with respect
to the related preferred stock.

  Unless specified otherwise in the applicable prospectus supplement, neither
we nor the depositary will be liable if either of us is prevented from or
delayed in, by law or any circumstances beyond its control, performing its
obligations under the Deposit Agreement. The obligations of the depositary and
our company under the Deposit Agreement will be limited to performing their
duties thereunder in good faith and without negligence, in the case of any
action or inaction in the voting of preferred stock represented by the
depositary shares, gross negligence or willful misconduct, and we and the
depositary will not be obligated to prosecute or defend any legal proceeding
in respect of any depositary receipts, depositary shares or shares of
preferred stock represented thereby unless satisfactory indemnity is
furnished. We and the depositary may rely on written advice of counsel or
accountants, or information provided by persons presenting shares of preferred
stock represented thereby for deposit, holders of depositary receipts or other
persons believed in good faith to be competent to give such information, and
on documents believed in good faith to be genuine and signed by a proper
party.

  In the event the depositary shall receive conflicting claims, requests or
instructions from any holders of depositary receipts, on the one hand, and us,
on the other hand, the depositary shall be entitled to act on such claims,
requests or instructions received from us.

                         DESCRIPTION OF DEBT SECURITIES

  The following discussion describes certain general provisions of the debt
securities to which this prospectus and any applicable prospectus supplement
may relate. The particular terms of the debt securities being offered and the
extent to which these general provisions may apply will be set forth in the
indenture or supplemental indenture under which the particular debt securities
are issued, and will be described in a prospectus supplement relating to such
debt securities. A form of the senior indenture and a form of the subordinated
indenture under which the debt securities may be issued have been filed as
exhibits to the registration statement of which this prospectus is a part. All
section references appearing in this prospectus are to sections of each
indenture unless otherwise indicated, and capitalized terms used but not
defined below shall have the respective meanings set forth in each Indenture.

General

  Our debt securities will be unsecured general obligations and may be either
senior debt securities, which we refer to as Senior Securities, or subordinated
debt securities, which we refer to as Subordinated Securities. The debt
securities will be issued pursuant to a written agreement, known as an
Indenture, to be entered into by us and an independent third party, known as a
Trustee, who will be legally obligated to carry out the terms of the Indenture.
Senior Securities and Subordinated Securities will be issued under separate
indentures referred to as a Senior Indenture and a Subordinated Indenture,
respectively, or together referred to as the Indentures. The statements made
under this heading relating to the debt securities and the Indentures are
summaries of their anticipated provisions, do not purport to be complete and
are qualified in their entirety by reference to the Indentures and the debt
securities themselves.

  The indebtedness represented by Subordinated Securities will be subordinated
in right of payment to the prior payment in full of our Senior Indebtedness
(which term includes our Senior Securities), as described below under "--
Ranking."

  All of our operations are conducted through subsidiaries. Our subsidiaries
are separate and distinct legal entities and have no obligation, contingent or
otherwise, to pay any amounts due pursuant to the debt securities or to make
any funds available therefor, whether by dividends, loans or other payments,
other than as expressly provided in a guarantee. The payment of dividends or
the making of loans and advances to us by our subsidiaries may be subject to
contractual, statutory or regulatory restrictions, which, if material, would be
disclosed in the applicable prospectus supplement. Moreover, such payments,
loans and advances would be contingent upon the earnings of the subsidiaries.
Any right we may have to receive assets of any of our subsidiaries upon
liquidation or recapitalization of the subsidiaries (and the consequent right
of the holders of debt securities to participate in those assets) will be
subject to the claims of the subsidiaries' creditors. In the event that we are
recognized as a creditor of a subsidiary, our claims would still be subject to
any security interest in the assets of such subsidiary and any indebtedness of
such subsidiary senior to that of the debt securities, and would be dependent
primarily upon the receipt of funds from our subsidiaries.

  Except as set forth in the applicable Indenture or in one or more
supplemental indentures and described in an applicable prospectus supplement,
the debt securities may be issued without limit as to aggregate principal
amount, in one or more series, in each case as established from time to time in
or under authority granted by a resolution of our board of directors or as
established in the applicable Indenture or in one or more supplemental
indentures. All debt securities of one series need not be issued at the same
time and, unless otherwise provided, a series may be reopened, without the
consent of the holders of the debt securities of such series, for issuances of
additional debt securities of such series.

  It is expected that each Indenture will provide that there may be more than
one Trustee thereunder, each with respect to one or more series of debt
securities. Any Trustee under an Indenture may resign or be removed with
respect to one or more series of debt securities, and a successor Trustee may
be appointed to act with

                                       16
<PAGE>

respect to such series. In the event that two or more persons are acting as
Trustee with respect to different series of debt securities, each such Trustee
will be a trustee of a trust under the applicable Indenture separate and apart
from the trust administered by any other Trustee, and, except as otherwise
provided in the Indenture or supplemental indenture, any action permitted to be
taken by each Trustee may be taken by each such Trustee with respect to, and
only with respect to, the one or more series of debt securities for which it is
Trustee under the applicable Indenture.

  The applicable prospectus supplement will describe the specific terms of any
series of debt securities being offered, including:

  (1)  The title of such debt securities and whether such debt securities are
       Senior Securities or Subordinated Securities

  (2)  The aggregate principal amount of such debt securities and any limit
       on such aggregate principal amount

  (3)  The percentage of the principal amount at which such debt securities

  (4)  The date or dates, or the method for determining such date or dates,
       on which the principal of such debt securities will be payable and the
       amount of principal payable thereon

       which such rate or rates will be determined, at which such debt
       securities will bear interest, if any

       from which any such interest will accrue, the dates on which any such
       interest will be payable, the regular record dates for such interest
       payment dates, or the method by which record dates may be determined,
       the persons to whom such interest will be payable, and the basis upon
       which interest is to be calculated if other than a 360-day year of
       twelve 30-day months

  (7)  The place or places where the principal of (and premium, if any) and
       interest, if any, on such debt securities will be payable, where such

       exchange and where notices or demands to or upon us in respect of such
       debt securities and the applicable Indenture may be served

  (8)  The period or periods within which, the price or prices at which, and

       securities pursuant to any sinking fund or analogous provision or at
       the option of a holder thereof, and the period or periods within
       which, the date and dates on which, the price or prices at which, and
       the other terms and conditions upon which, such debt securities will
       be redeemed, repaid or purchased, in whole or in part, pursuant to
       such obligation

  (10) If other than U.S. dollars, the currency or currencies in which such
       debt securities are denominated or in which the principal of (and
       premium, if any) or interest or Additional Amounts (as defined below),
       if any, on the debt securities is payable, which may be a foreign

  (11)  Whether the amount of payments of principal of (and premium, if any)
        or interest or Additional Amounts, if any, on such debt securities

        currency, currencies, currency unit or units or composite currency or
        currencies) and the manner in which such amounts are to be determined

                                       17

        currency or currencies, currency unit or units or composite currency
        or currencies in which such debt securities are to be so payable

  (13)  Any additions to, modifications of or deletions from the terms of

        of any tax, assessment or governmental charge and, if so, whether we
        will have the option to redeem such debt securities in lieu of making

or bear no interest or bear interest at a rate which at the time of issuance is
below market rates, which we refer to as Original Issue Discount Securities.
Special U.S. federal income tax, accounting and other considerations applicable
to Original Issue Discount Securities will be described in the applicable
prospectus supplement.

  Except as set forth in the applicable Indenture or in one or more
supplemental indentures, the applicable Indenture will not contain any
provisions that would limit our ability to incur indebtedness or that would
afford you protection in the event of a highly leveraged or similar transaction
involving us or in the event of a change of control. You should refer to the
applicable prospectus supplement for information with respect to any deletions
from, modifications of or additions to the Events of Default or our covenants
that are described below, including any addition of a covenant or other
provision providing event risk or similar protection.

  For the purposes of certain Events of Default described below and any
additional covenants or other provisions that may be set forth in one or more
supplemental indentures, we may designate certain of our Subsidiaries as
"Unrestricted Subsidiaries." All Subsidiaries that are not designated as
Unrestricted Subsidiaries will be "Restricted Subsidiaries." The terms and
conditions, if any, under which a Subsidiary may be designated as an
Unrestricted Subsidiary will be set forth in the applicable supplemental
indenture and described in the applicable prospectus supplement.

                                       18
<PAGE>

  We refer to a corporation, partnership, limited liability company, joint
venture or similar entity in which we or one or more of our other Subsidiaries
own or control, directly or indirectly, a majority of the outstanding voting
stock, partnership interests, membership interests or similar interests, as the
case may be, as a "Subsidiary." For the purposes of this definition, "voting
stock" means stock or other equity interests having voting power for the
election of directors, or comparable governing body, as the case may be,
whether at all times or only so long as no senior class of stock has such
voting power by reason of any contingency.

Denomination, Interest, Registration and Transfer

  Unless otherwise described in the applicable prospectus supplement, dollar-
denominated debt securities that are in registered form will be issuable in
denominations of $1,000 and any integral multiple thereof (except for
registered debt securities issued in global form, which may be of any
denomination), and dollar-denominated debt securities that are in bearer form
will be issuable in denominations of $5,000 (except for bearer debt securities
issued in global form, which may be of any denomination) (Section 302).

  Unless otherwise specified in the applicable prospectus supplement, the
principal of (and applicable premium, if any) and interest (and Additional
Amounts, if any) on any series of debt securities that are in registered form
will be payable at the corporate trust office of the Trustee, the address of
which will be stated in the applicable prospectus supplement. At our option,
payment of interest on debt securities that are in registered form may be made
by check mailed to the address of the person entitled thereto as it appears in
the applicable register for such debt securities or by wire transfer of funds
to such person at an account maintained within the United States. Unless
otherwise specified in the applicable prospectus supplement, payment of the
principal of (and applicable premium, if any) and interest (and Additional
Amounts, if any) on any debt securities that are in bearer form will be made
only at an office or agency of ours located outside the United States (Sections
301, 305, 306, 307 and 1002).

  Any interest not punctually paid or duly provided for on any interest payment
date with respect to a debt security, which we refer to as Defaulted Interest,
will forthwith cease to be payable to the holder on the applicable regular
record date and may either be paid to the person in whose name such debt
security is registered at the close of business on a special record date, which
we refer to as the Special Record Date, for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof is to be given to the
holder of such debt security not less than ten days before such Special Record
Date, or may be paid at any time in any other lawful manner, all as more
completely described in the applicable Indenture or supplemental indenture
(Section 307).

  Subject to certain limitations imposed upon debt securities issued in book-
entry form, the debt securities of any series will be exchangeable for other
debt securities of the same series and of a like aggregate principal amount and
tenor of different authorized denominations upon surrender of such debt
securities at the corporate trust office of the applicable Trustee. In
addition, subject to certain limitations imposed upon debt securities issued in
book-entry form, the debt securities of any series may be surrendered for
registration of transfer or exchange thereof at the corporate trust office of
the applicable Trustee. Every debt security surrendered for registration of
transfer or exchange must be duly endorsed or accompanied by a written
instrument of transfer. No service charge will be made for any registration of
transfer or exchange of any debt securities, but we may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith (Section 305). If the applicable prospectus supplement
refers to any transfer agent (in addition to the applicable Trustee) initially
designated by us with respect to any series of debt securities, we may at any
time rescind the designation of such transfer agent or approve a change in the
location through which any such transfer agent acts, except that we will be
required to maintain a transfer agent in each place of payment for such series.
We may at any time designate additional transfer agents with respect to any
series of debt securities (Section 1002).

                                       19
<PAGE>

  Neither we nor any Trustee will be required to:

  (1)  issue, register the transfer of or exchange debt securities of any
       series during a period beginning at the opening of business 15 days
       before any selection of debt securities of that series to be redeemed
       and ending at the close of business on the day of mailing of the
       relevant notice of redemption

  (2)  register the transfer of or exchange any debt security, or portion
       thereof, called for redemption, except the unredeemed portion of any
       debt security being redeemed in part, or

  (3)  issue, register the transfer of or exchange any debt security that has
       been surrendered for repayment at the option of the holder, except the
       portion, if any, of such debt security not to be repaid (Section 305)

Merger, Consolidation or Sale of Assets

  We will be permitted to consolidate with, or sell, lease or convey all or
substantially all of our assets to, or merge with or into, any other entity,
provided that:

  (1)  either we are the continuing entity, or the successor entity (if other
       than us) formed by or resulting from any such consolidation or merger
       or which has received the transfer of such assets is an entity
       organized or existing under the laws of the United States, any state
       thereof or the District of Columbia and expressly assumes payment of
       the principal of (and premium, if any), interest on, and all other
       amounts payable in connection with, all of the outstanding debt
       securities and the due and punctual performance and observance of all
       of the covenants and conditions contained in each Indenture

  (2)  immediately after giving effect to such transaction and treating any
       indebtedness that becomes an obligation of us or any Subsidiary as a
       result thereof as having been incurred by us or such Subsidiary at the
       time of such transaction, no Event of Default under the Indentures or
       supplemental indentures, and no event which, after notice or the lapse
       of time, or both, would become such an Event of Default, will have
       occurred and be continuing, and

  (3)  an officer's certificate and legal opinion covering such conditions
       are delivered to each Trustee (Sections 801 and 803)

Certain Covenants

  Existence. Except as described above under "Merger, Consolidation or Sale of
Assets," we will be required to do or cause to be done all things necessary to
preserve and keep in full force and effect our existence, rights (by
certificate of incorporation, by-laws and statute) and franchises, and those of
our Restricted Subsidiaries, but we and any such Restricted Subsidiary will not
be required to preserve the existence of a Restricted Subsidiary or any such
right or franchise if we determine that the preservation of such existence,
right or franchise is no longer desirable in the conduct of our business and
that the loss of such right or franchise is not disadvantageous in any material
respect to the holders of the debt securities. Furthermore, any Restricted
Subsidiary may consolidate with, merge into, or sell, convey, lease or
otherwise dispose of all of its property and assets to us or any wholly owned
Restricted Subsidiary (Section 1004).

  Maintenance of Properties. We will be required to cause all of our properties
used or useful in the conduct of our business or the business of any Restricted
Subsidiary and material to us and our Restricted Subsidiaries taken as a whole
to be maintained and kept in good condition, repair and working order and
supplied with all necessary equipment and to cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as
in our judgment may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times, but we and
our Restricted Subsidiaries will not be prevented from discontinuing the
operation or maintenance of any of such property if such discontinuance is in
our judgment, desirable on the conduct of our business or the business of any
of our Restricted Subsidiaries (Section 1005).

                                       20

  Payment of Taxes and Other Claims. We will be required to pay or discharge or
cause to be paid or discharged, before the same become delinquent:

  (1)  all material taxes, assessments and governmental charges levied or
       imposed upon us or any Restricted Subsidiary or upon our income,
       profits or property or that of any Restricted Subsidiary and

  (2)  all material lawful claims for labor, materials and supplies that, if
       unpaid, might by law become a lien upon our property or that of any
       Restricted Subsidiary; but we will not be required to pay or discharge
       or cause to be paid or discharged any such tax, assessment, charge or
       claim whose amount, applicability or validity is being contested in
       good faith in appropriate proceedings upon stay of execution or the
       enforcement thereof and for which adequate reserves in accordance with
       GAAP or other appropriate provision has been made. (Section 1007).

Additional Covenants and/or Modifications to the Covenants Described Above

  Any additional covenants and/or modifications to the covenants described
above with respect to any series of our debt securities, including any
covenants relating to limitations on incurrence of indebtedness or other
financial covenants, will be set forth in the applicable Indenture or
supplemental indenture and described in the related prospectus supplement.

Events of Default, Notice and Waiver

  Each Indenture may provide that some or all of the following events are
"Events of Default" with respect to any series of debt securities issued
thereunder, subject to any modifications, additions or deletions provided in
any supplemental indenture with respect to any series of debt securities:

  (1)  default for 30 days in the payment of any installment of interest on
       or any Additional Amounts payable in respect of any debt security of
       such series

  (2)  default in the payment of principal of (or premium, if any, on) any
       debt security of such series when such amount becomes due and payable,
       whether upon its maturity, declaration of acceleration, call for
       redemption or otherwise

  (3)  default in making any sinking fund payment as required for any debt
       security of such series

  (4)  default in the performance, or breach, of any of our other covenants
       or warranties contained in the applicable Indenture (other than any
       covenant or warranty otherwise provided for in the provisions relating
       to Events of Default), continued for 60 days after written notice as
       provided in the applicable Indenture

  (5)  certain events of bankruptcy, insolvency or reorganization, or court
       appointment of a receiver, liquidator or trustee of us or any
       Restricted Subsidiary or either of their property

  (6)  any other Event of Default provided with respect to a particular
       series of debt securities (Section 501)

  If an Event of Default under an Indenture (other than an Event of Default
described in clause 5 above) with respect to debt securities of any series at
the time outstanding occurs and is continuing, then in every such case, unless
the principal amount of all of the outstanding debt securities of such series
has already become due and payable, the applicable Trustee or, generally, the
holders of not less than 25% of the principal amount of the outstanding debt
securities of that series will have the right to declare the principal amount
(or, if the debt securities of that series are Original Issue Discount
Securities or indexed securities, such portion of the principal amount as may
be specified in the terms thereof) of all the debt securities of that series,
and any accrued and unpaid interest thereon, to be due and payable immediately
by written notice thereof to us (and to the applicable Trustee if given by the
holders) and upon any such declaration such principal or specified portion
thereof and any accrued and unpaid interest thereon shall become immediately
due and payable. If an Event of Default described in clause 5 above occurs with
respect to the debt securities of any series, then the principal amount of all
debt securities of that series and any accrued and unpaid interest thereon
shall become immediately due and payable without any act on the part of the
Trustee or any holder of such debt securities. At any time after such a
declaration of acceleration with respect to debt securities of such series (or
of all debt securities then outstanding under any Indenture, as the case may
be)

                                       21
<PAGE>

has been made, but before a judgment or decree for payment of the money due has
been obtained by the applicable Trustee, however, the holders of not less than
a majority in principal amount of the outstanding debt securities of such
series (or of all debt securities then outstanding under the applicable
Indenture, as the case may be) may rescind and annul such declaration and its
consequences if:

  (1)  we have deposited with the applicable Trustee all required payments of
       the principal of (and premium, if any) and interest and Additional
       Amounts, if any, on the debt securities of such series (or of all debt
       securities then outstanding under the applicable Indenture, as the
       case may be), plus certain fees, expenses, disbursements and advances
       of the applicable Trustee, and

  (2)  all Events of Default, other than the non-payment of accelerated
       principal (or specified portion thereof), with respect to debt
       securities of such series (or of all debt securities then outstanding
       under the applicable Indenture, as the case may be) have been cured or
       waived as provided in such Indenture (Section 502)

  Each Indenture also will provide that the holders of not less than a majority
in principal amount of the outstanding debt securities of any series (or of all
debt securities then outstanding under the applicable Indenture, as the case
may be) may waive any past default with respect to such series and its
consequences, except a default:

  (1)  in the payment of the principal of (or premium, if any) or interest or
       Additional Amounts, if any, on any debt security of such series, or

  (2)  in respect of a covenant or provision contained in the applicable
       Indenture that cannot be modified or amended without the consent of
       the holder of each outstanding debt security affected thereby (Section
       513)

  Each Trustee will be required to give notice to the holders of the applicable
debt securities within 90 days of a default under the applicable Indenture
unless such default has been cured or waived; but the Trustee may withhold
notice of any default (except a default in the payment of the principal of (or
premium, if any) or interest or Additional Amounts, if any, on such debt
securities or in the payment of any sinking fund installment in respect of such
debt securities) if specified responsible officers of such Trustee consider
such withholding to be in the interest of such holders (Section 601).

  Each Indenture will provide that no holders of debt securities of any series
may institute any proceedings, judicial or otherwise, with respect to such
Indenture or for any remedy thereunder, except in the cases of failure of the
applicable Trustee, for 60 days, to act after it has received a written request
to institute proceedings in respect of an Event of Default from the holders of
not less than 25% in principal amount of the outstanding debt securities of
such series, as well as an offer of indemnity reasonably satisfactory to it
(Section 507). This provision will not prevent any holder of debt securities
from instituting suit for the enforcement of payment of the principal of (and
premium, if any) and interest and Additional Amounts, if any, on such debt
securities at the respective due dates thereof (Section 508).

  Subject to provisions in each Indenture relating to its duties in case of
default, no Trustee will be under any obligation to exercise any of its rights
or powers under an Indenture at the request or direction of any holders of any
series of debt securities then outstanding under such Indenture, unless such
holders offer to the Trustee reasonable security or indemnity (Section 602).
The holders of not less than a majority in principal amount of the outstanding
debt securities of any series (or of all debt securities then outstanding under
an Indenture, as the case may be) will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
applicable Trustee, or of exercising any trust or power conferred upon such
Trustee. A Trustee may refuse, however, to follow any direction that is in
conflict with any law or with the applicable Indenture or that may involve such
Trustee in personal liability or may be unduly prejudicial to the holders of
debt securities of such series not joining therein (Section 512).

  Within 120 days after the close of each fiscal year, we will be required to
deliver to each Trustee a certificate, signed by one of several specified
officers, stating whether or not such officer has knowledge of any default
under the applicable Indenture and, if so, specifying each such default and the
nature and status thereof (Section 1008).


                                       22

Modification of the Indentures

  Modifications and amendments of an Indenture will be permitted to be made
only with the consent of the holders of not less than a majority in principal
amount of all outstanding debt securities issued under such Indenture that are
affected by such modification or amendment; but no such modification or
amendment may, without the consent of the holder of each such debt security
affected thereby:

  (1)  change the stated maturity of the principal of (or the premium, if
       any), or any installment of interest (or Additional Amounts, if any)
       on, any such debt security

  (2)  reduce the principal amount of, or the rate or amount of interest on,
       or any premium payable on redemption of, or any Additional Amounts
       payable with respect to, any such debt security, or reduce the amount
       of principal of an Original Issue Discount Security that would be due
       and payable upon declaration of acceleration of the maturity thereof
       or would be provable in bankruptcy, or adversely affect any right of
       repayment of the holder of any such debt security

  (3)  change the place of payment, or the coin or currency for payment, of
       principal (or premium, if any) or interest or Additional Amounts, if
       any, on any such debt security

  (4)  impair the right to institute suit for the enforcement of any payment
       on or with respect to any such debt security

  (5)  release any guarantors from their guarantees of any such debt
       securities, or, except as contemplated in any supplemental indenture,
       make any change in a guarantee of such debt securities that would
       adversely affect the interests of the holders thereof

  (6)  reduce the percentage in principal amount of outstanding debt
     securities of any series necessary to modify or amend the Indenture, to
     wave compliance with certain provisions thereof or certain defaults or
     consequences thereunder or to reduce the quorum or voting requirements
     in the Indenture, or

  (7)  modify the ranking or priority of such debt securities (Section 902)

  The holders of not less than a majority in principal amount of the
outstanding debt securities of each series affected thereby will have the right
to waive compliance by us with certain covenants in such Indenture (Section
1010).

  Modifications and amendments of an Indenture will be permitted to be made by
us and the Trustee thereunder without the consent of any holder of debt
securities for any of the following purposes:

  (1)  to evidence the succession of another person to us as obligor under
       such Indenture

  (2)  to add to our covenants for the benefit of the holders of all or any
       series of debt securities or to surrender any right or power conferred
       upon us in the Indenture

  (3)  to add Events of Default for the benefit of the holders of all or any
       series of debt securities

  (4)  to add or change any provisions of an Indenture to facilitate the
       issuance of, or to liberalize certain terms of, debt securities in
       bearer form, or to permit or facilitate the issuance of debt
       securities in uncertificated form, provided that such action shall not
       adversely affect the interests of the holders of the debt securities
       of any series in any material respect

  (5)  to change or eliminate any provisions of an Indenture, if such change
       or elimination becomes effective only when there are no debt
       securities outstanding of any series created prior thereto that are
       entitled to the benefit of such provision

  (6)  to secure the debt securities

  (7)  to establish the form or terms of debt securities of any series

  (8)  to provide for the acceptance of appointment by a successor Trustee or
       facilitate the administration of the trusts under an Indenture by more
       than one Trustee

  (9)  to cure any ambiguity, defect or inconsistency in an Indenture,
       provided that such modifications shall not adversely affect the
       interests of the holders of debt securities of any series


                                       23
<PAGE>


  (10) to supplement any of the provisions of an Indenture to the extent
       necessary to permit or facilitate defeasance and discharge of any
       series of such debt securities, if such action does not adversely
       affect the interests of the holders of the debt securities of any
       series in any material respect

  (11) to make any change that does not adversely affect the legal rights
       under an Indenture of any holder of debt securities of any series
       issued thereunder

  (12) to add a guarantor of the securities of any series, or

  (13) to comply with the requirements of the SEC in order to effect or
       maintain the qualification of the Indenture under the Trust Indenture
       Act (Section 901)

Ranking

  The Senior Securities will constitute part of our Senior Indebtedness (as
defined below) and will rank pari passu with all of our outstanding senior
debt. Except as set forth in the applicable prospectus supplement, the
Subordinated Securities will be subordinated, in right of payment, to the prior
payment in full of the Senior Indebtedness, including the Senior Securities.
However, our obligation to pay the principal of (and premium, if any) and
interest and Additional Amounts (if any) on such Subordinated Securities will
not otherwise be impaired (Section 1603 of the Subordinated Indenture).

  In the event of any distribution of our assets in connection with any
dissolution, winding up, liquidation or reorganization of us, whether in a
bankruptcy, insolvency, reorganization or receivership proceeding or upon an
assignment for the benefit of creditors or any other marshalling of our assets
and liabilities or otherwise, except a distribution in connection with a
merger, consolidation or sale of assets that complies with the requirements
described above under "Merger, Consolidation or Sale of Assets," the holders of
all Senior Indebtedness will first be entitled to receive payment of the full
amount due thereon before the holders of any of the Subordinated Securities
will be entitled to receive any payment in respect of the Subordinated
Securities. If a payment default occurs and is continuing with respect to any
amount payable in respect of any Senior Indebtedness, or if any event occurs
that would permit the holders of any Senior Indebtedness to accelerate the
maturity thereof, the holders of all Senior Indebtedness will first be entitled
to receive payment of the full amount due thereon before the holders of any of
the Subordinated Securities will be entitled to receive any payment in respect
of the Subordinated Securities. If the principal amount of the Subordinated
Securities of any series is declared due and payable pursuant to the
Subordinated Indenture and such declaration has not been rescinded and
annulled, the holders of all Senior Indebtedness outstanding at the time of
such declaration will first be entitled to receive payment of the full amount
due thereon before the holders of any of the Subordinated Securities will be
entitled to receive any payment in respect of the Subordinated Securities
(Section 1601 of the Subordinated Indenture).

  After all Senior Indebtedness is paid in full and until the Subordinated
Securities are paid in full, holders of Subordinated Securities will be
subrogated to the right of holders of Senior Indebtedness to the extent that
distributions otherwise payable to holders of Subordinated Securities have been
applied to the payment of Senior Indebtedness (Section 1602 of the Subordinated
Indenture). By reason of such subordination, in the event of a distribution of
assets upon insolvency, certain of our general creditors may recover more,
ratably, than holders of Subordinated Securities.

  Senior Indebtedness will be defined in the Subordinated Indenture as the
principal of (and premium, if any) and interest and Additional Amounts, if any,
on, or substantially similar payments to be made by us in respect of, the
following, whether outstanding at the date of execution of the applicable
Indenture or thereafter incurred, created, guaranteed or assumed, and whether
or not contingent:

  (1) any obligation for money borrowed

  (2) any obligation evidenced by bonds, debentures, notes, guarantees or
      other similar instruments, including, without limitation, any such
      obligations incurred in connection with the acquisition of property,
      assets or businesses, excluding trade accounts payable made in the
      ordinary course of business

                                       24
<PAGE>


  (3) any reimbursement obligation with respect to letters of credit,
      bankers' acceptances or similar facilities

  (4) any obligation issued or assumed as the deferred purchase price of
      property or services (but excluding trade accounts payable or accrued
      liabilities arising in the ordinary course of business, which in either
      case are not more than 60 days overdue or which are being contested in
      good faith)

  (5) any capital lease obligation

  (6) the maximum fixed redemption or repurchase price of capital stock
      which, by its terms, matures, is mandatorily redeemable or redeemable
      at the option of the holder thereof, or is exchangeable for
      indebtedness at any time, and, to the extent held by persons other than
      us or our Restricted Subsidiaries, the maximum fixed redemption or
      repurchase price of any such stock of our Restricted Subsidiaries, at
      the time of determination

  (7) every obligation under interest rate and currency protection agreements

  (8) any attributable indebtedness with respect to any sale and leaseback
      transaction and

  (9) any obligation of the type referred to in clauses (1) through (8) of
      another person and all dividends and distributions of another person
      the payment of which, in either case, we have guaranteed or are
      responsible or liable, directly or indirectly, as obligor, guarantor or
      otherwise

in each case other than (i) any such indebtedness, obligation or liability
referred to in clauses (1) through (9) above as to which, in the instrument
creating or evidencing the same pursuant to which the same is outstanding, it
is provided that such indebtedness, obligation or liability is not superior in
right of payment to the Subordinated Securities or ranks equally with the
Subordinated Securities, (ii) any such indebtedness, obligation or liability
which is subordinated to our indebtedness to substantially the same extent as
or to a greater extent than the Subordinated Securities are subordinated, and
(iii) the Subordinated Securities.

Satisfaction and Discharge of the Indentures

  We may terminate our obligations under either Indenture with respect to debt
securities of any series when:

  (1) either (A) all outstanding debt securities of such series have been
      delivered to the Trustee for cancellation or (B) all debt securities of
      such series not theretofore delivered to the Trustee for cancellation
      have become due and payable, will become due and payable at their
      Stated Maturity within one year or, if redeemable at our option, are to
      be called for redemption within one year under arrangements
      satisfactory to the Trustee for the giving of notice of redemption by
      the Trustee in our name and at our expense, and we have irrevocably
      deposited or caused to be deposited with the Trustee funds in an amount
      sufficient to pay and discharge the entire indebtedness on such debt
      securities not theretofore delivered to the Trustee for cancellation,
      for the principal of (and premium, if any,) and interest and Additional
      Amounts, if any, to the date of deposit or Stated Maturity or date of
      redemption,

  (2) we have paid or caused to be paid all sums payable by us under such
      Indenture, and

  (3) we have delivered a Company Certificate and an Opinion of Counsel
      relating to compliance with the conditions set forth in such Indenture
      (Section 401).

Defeasance and Covenant Defeasance

  Each Indenture will provide that, if the provisions relating to defeasance or
covenant defeasance or both are made applicable to the debt securities of or
within any series, we may elect either:

  (1) to defease and be deemed to have paid and be discharged from any and
      all obligations with respect to such debt securities, which we refer to
      as defeasance (except for the obligation to pay additional amounts, if
      any, upon the occurrence of certain events of tax, assessment or
      governmental charge

                                       25
<PAGE>

     with respect to payments on such debt securities, and the obligations to
     register the transfer or exchange of such debt securities, to replace
     temporary or mutilated, destroyed, lost or stolen debt securities, to
     maintain an office or agency in respect of such debt securities and to
     hold moneys for payment in trust) (Section 1402), or

  (2) to be released from our obligations with respect to such debt
      securities under certain specified covenants contained in Article Ten
      of such Indenture and, if so specified in any supplemental indenture
      relating to a series of debt securities, from any obligations arising
      under additional covenants applicable to such series of debt
      securities, all as described in the applicable prospectus supplement,
      and any omission to comply with such obligations shall not constitute
      an Event of Default with respect to such debt securities, which we
      refer to as covenant defeasance (Section 1403)

in either case upon the irrevocable deposit by us with the applicable Trustee,
in trust, of an amount, in such currency or currencies, currency unit or units
or composite currency or currencies in which such debt securities are payable
at stated maturity, or government obligations, or both, applicable to such debt
securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient without
reinvestment to pay the principal of (and premium, if any) and interest and
Additional Amounts, if any, on such debt securities, and any mandatory sinking
fund or analogous payments thereon, on the scheduled due dates therefor.

  Such a trust will only be permitted to be established if, among other things,
we have delivered to the applicable Trustee an opinion of counsel (as specified
in the applicable Indenture) to the effect that the holders of such debt
securities will not recognize income, gain or loss for federal income tax
purposes as a result of such defeasance or covenant defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such defeasance or covenant
defeasance had not occurred, and such opinion of counsel, in the case of
defeasance, will be required to refer to and be based upon a ruling of the
Internal Revenue Service or a change in applicable U.S. federal income tax law
occurring after the date of the Indenture (Section 1404).

  The applicable prospectus supplement may further describe the provisions, if
any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the debt
securities of or within a particular series.

Conversion and Exchange

  The terms, if any, on which debt securities of any series are convertible
into or exchangeable for Class A common stock, preferred stock, or other debt
securities, including the initial conversion price or conversion rate, any
adjustments to such conversion price or conversion rate and the conversion
period, and the conditions upon which such conversion will be effected, will be
set forth in the applicable prospectus supplement. Such terms may include
provisions for conversion or exchange to be either mandatory or at the option
of the holders or ourselves.

Redemption and Repurchase

  The debt securities may be redeemable at our option, may be subject to
mandatory redemption pursuant to a sinking fund or otherwise, or may be subject
to repurchase by us at the option of the holders, in each case upon the terms,
at the times and at the prices set forth in the applicable prospectus
supplement.

Global Securities

  The debt securities of a series may be issued in whole or in part in the form
of one or more global securities, which we refer to as the Global Securities,
to be deposited with, or on behalf of, a depository identified in the
applicable prospectus supplement relating to such series. Global Securities may
be issued in either registered or bearer form and in either temporary or
permanent form. The specific terms of the depository arrangement with respect
to a series of debt securities will be described in the applicable prospectus
supplement relating to such series.

        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

  We may issue stock purchase contracts, including contracts obligating holders
to purchase from us, and obligating us to sell to the holders, a specified
number of shares of Class A common stock, Class B common stock or preferred
stock at a future date or dates. The price per share of Class A common stock,
Class B common stock or preferred stock may be fixed at the time the stock
purchase contracts are issued or may be determined by a specific reference to a
formula set forth in the stock purchase contracts. The stock purchase contracts
may be issued separately or as part of stock purchase units consisting of (1) a
stock purchase contract and (2) debt securities, preferred securities or debt
obligations of third parties, including U.S. Treasury securities, securing the
holders' obligations to purchase the Class A common stock, Class B common stock
or the preferred stock under the stock purchase contracts. The stock purchase
contracts may require us to make periodic payments to the holders of the stock
purchase units or vice versa, and such payments may be unsecured or prefunded
on some basis. The stock purchase contracts may require holders to secure their
obligations thereunder in a specified manner.

  Unless otherwise specified in the applicable prospectus supplement, the
securities related to the stock purchase contracts will be pledged to a
collateral agent, for our benefit, pursuant to a pledge agreement. The pledged
securities will secure the obligations of holders of stock purchase contracts
to purchase Class A common stock, Class B common stock or preferred stock under
the related stock purchase contracts. The rights of holders of stock purchase
contracts to the related pledged securities will be subject to our security
interest in those pledged securities. That security interest will be created by
the pledge agreement. No holder of stock purchase contracts will be permitted
to withdraw the pledged securities related to such stock purchase contracts
from the pledge arrangement except upon the termination or early settlement of
the related stock purchase contracts. Subject to that security interest and the
terms of the purchase contract agreement and the pledge agreement, each holder
of a stock purchase contract will retain full beneficial ownership of the
related pledged securities.

  Except as described in the applicable prospectus supplement, the collateral
agent will, upon receipt of distributions on the pledged securities, distribute
such payments to us or a purchase contract agent, as provided in the pledge
agreement. The purchase contract agent will in turn distribute payments it
receives as provided in the stock purchase contract. The applicable prospectus
supplement will describe the terms of any stock purchase contracts or stock
purchase units.

                       DESCRIPTION OF SUBSCRIPTION RIGHTS

General

  We may issue subscription rights to purchase our debt securities, Class A
common stock, Class B common stock, preferred stock, depositary shares or
warrants to purchase debt securities, preferred stock, Class A common stock or
Class B common stock. We may issue subscription rights independently or
together with any other offered security. The subscription rights may or may
not be transferable by the purchaser receiving the subscription rights. In
connection with any subscription rights offering to our stockholders, we may
enter into a standby underwriting arrangement with one or more underwriters
pursuant to which the underwriter(s) will purchase any offered securities
remaining unsubscribed for after the subscription rights offering. In
connection with a subscription rights offering to our stockholders,
certificates evidencing the subscription rights and a prospectus supplement
will be distributed to our stockholders on the record date for receiving
subscription rights in the subscription rights offering set by us.

  The applicable prospectus supplement will describe the following terms of
subscription rights in respect of which this prospectus is being delivered:

  (1)  the title of the subscription rights

  (2)  the securities for which the subscription rights are exercisable

  (3)  the exercise price for the subscription rights

  (4)  the number of subscription rights issued to each stockholder

  (5)  the extent to which the subscription rights are transferable

  (6)  if applicable, a discussion of the material United States federal
       income tax considerations applicable to the issuance or exercise of
       the subscription rights

  (7)  any other terms of the subscription rights, including terms,
       procedures and limitations relating to the exchange and exercise of
       the subscription rights

  (8)  the date on which the right to exercise the subscription rights shall
       commence, and the date on which the right shall expire

  (9)  the extent to which the subscription rights include an over-
       subscription privilege with respect to unsubscribed securities

  (10)  if applicable, the material terms of any standby underwriting
        arrangement entered into by us in connection with the subscription
        rights offering

Exercise Of Subscription Rights

  Each subscription right will entitle the holder of subscription rights to
purchase for cash the principal amount of debt securities, shares of preferred
stock, depositary shares, Class A common stock, Class B common stock, warrants
or any combination thereof, at the exercise price as shall in each case be set
forth in, or be determinable as set forth in, the applicable prospectus
supplement. Subscription rights may be exercised at any time up to the close of
business on the expiration date for such subscription rights set forth in the
applicable prospectus supplement. After the close of business on the expiration
date, all unexercised subscription rights will become void.

  Subscription rights may be exercised as set forth in the applicable
prospectus supplement. Upon receipt of payment and the subscription rights
certificate properly completed and duly executed at the corporate trust office
of the subscription rights agent or any other office indicated in the
prospectus supplement, we will, as soon as practicable, forward the debt
securities, shares of preferred stock, Class A common stock or Class B common
stock, depositary shares or warrants purchasable upon such exercise. In the
event that not all of the subscription rights issued in any offering are
exercised, we may determine to offer any unsubscribed offered securities
directly to persons other than stockholders, to or through agents, underwriters
or dealers or through a combination of such methods, including pursuant to
standby underwriting arrangements, as set forth in the applicable prospectus
supplement.

the underwriting arrangements applicable to such offering.

  We may sell the securities in any of the following ways, or in any

  A prospectus supplement will set forth the terms of the offering of the

  If underwriters are used in the sale of any securities, such securities will
be acquired by the underwriters for their own account and may be resold from
time to time in one or more transactions, including negotiated transactions,
at a fixed public offering price or at varying prices determined at the time
of sale. Such securities may be either offered to the public through
underwriting syndicates represented by one or more managing underwriters, or

prospectus supplement are deemed to be underwriters in connection with the
securities offered thereby. Unless otherwise set forth in the applicable
prospectus supplement, the obligations of the underwriters to purchase such
securities will be subject to certain conditions precedent and the

any commissions payable by us to such agent will be set forth, in the
prospectus supplement. Unless otherwise indicated in the prospectus
supplement, any such agent will be acting on a best efforts basis for the
period of its appointment.

  If so indicated in the applicable prospectus supplement, we will authorize
underwriters, dealers or agents to solicit offers by institutional investors
to purchase the securities from us at the public offering price set forth in
the prospectus supplement pursuant to delayed delivery contracts providing for
payment and delivery on a specified date in the future. There may be
limitations on the minimum amount which may be purchased by any such
institutional investor or on the portion of the aggregate principal amount of
the particular securities which may be sold pursuant to such arrangements.
Institutional investors to which such offers may be made, when authorized,
include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions, and such other
institutions as may be approved by us. The obligations of any such purchasers
pursuant to such delayed delivery and payment arrangements will be subject

conditions set forth in the prospectus supplement, and the prospectus
supplement will set forth the commission payable for solicitation of such
contracts. Underwriters, dealers or agents will not have any responsibility in
respect of the validity of such arrangements or the performance of McLeodUSA or
such institutional investors thereunder.

  Securities offered other than Class A common stock may be a new issue of
securities with no established trading market. Unless otherwise indicated in
the applicable prospectus supplement, we do not intend to list any offered
securities other than our Class A common stock on any securities exchange or
other market. Any underwriters to whom such securities are sold by us for
public offering and sale may make a market in such securities, but such
underwriters will not be obligated to do so and may discontinue any market
making at any time without notice. No assurance can be given as to the
liquidity of or the trading markets for any such securities.

of business.

Item 15. Indemnification of Directors and Officers

  Under Section 145 of the Delaware General Corporation Law ("DGCL"), a
corporation may indemnify its directors, officers, employees and agents and
its former directors, officers, employees and agents and those who serve, at
the corporation's request, in such capacities with another enterprise, against
expenses (including attorneys' fees), as well as judgments, fines and
settlements in nonderivative lawsuits, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding in which they or
any of them were or are made parties or are threatened to be made parties by
reason of their serving or having served in such capacity. The DGCL provides,
however, that such person must have acted in good faith and in a manner such
person reasonably believed to be in (or not opposed to) the best interests of
the corporation and, in the case of a criminal action, such person must have
had no reasonable cause to believe his or her conduct was unlawful. In
addition, the DGCL does not permit indemnification in an action or suit by or
in the right of the corporation, where such person has been adjudged liable to
the corporation, unless, and only to the extent that, a court determines that
such person fairly and reasonably is entitled to indemnity for costs the court
deems proper in light of liability adjudication. Indemnity is mandatory to the
extent a claim, issue or matter has been successfully defended.

  The Amended and Restated Certificate of Incorporation of the Company (the
"Restated Certificate") contains provisions that provide that no director of
the Company shall be liable for breach of fiduciary duty as a director except
for (1) any breach of the directors' duty of loyalty to the Company or its
stockholders; (2) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law; (3) liability under
Section 174 of the DGCL; or (4) any transaction from which the director
derived an improper personal benefit. The Restated Certificate contains
provisions that further provide for the indemnification of directors and
officers to the fullest extent permitted by the DGCL. Under the Bylaws of the
Company, the Company is required to advance expenses incurred by an officer or
director in defending any such action if the director or officer undertakes to
repay such amount if it is determined that the director or officer is not
entitled to indemnification. In addition, the Company has entered into
indemnity agreements with each of its directors pursuant to which the Company
has agreed to indemnify the directors as permitted by the DGCL. The Company
has obtained directors and officers liability insurance against certain
liabilities, including liabilities under the Securities Act.

incorporated herein by reference:

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 the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in this
  registration statement;

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

  provided, however, that subparagraphs (i) and (ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in the periodic reports filed by the Registrant
pursuant to Section 13 or Section 15(d) of the Securities 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 herein, 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.

  The undersigned Registrant hereby undertakes that, for the 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 that is incorporated by reference in this
registration statement shall be

                                     II-4
<PAGE>

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.

  The undersigned Registrant hereby undertakes to supplement the prospectus,
after the expiration of the subscription period, to set forth the results of
the subscription offer, the transactions by the underwriters during the
subscription period, the amount of unsubscribed securities to be purchased by
the underwriters, and the terms of any subsequent reoffering thereof. If any
public offering by the underwriters is to be made on terms differing from
those set forth on the cover page of the prospectus, a post-effective
amendment will be filed to set forth the terms of such offering.

  The undersigned Registrant hereby undertakes that:

  (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance under 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 of 1933 shall be deemed to be part of this
registration statement as of the time it was declared effective.

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

  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 provisions described under Item 15 above 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 against the Registrant 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 Securities Act and will be governed
by the final adjudication of each issue.

  The undersigned Registrant hereby undertakes to file an application for
purposes of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Act.
