                                     PART I

Item 1.  Business.

Overview

     We provide communications services to business and residential customers in
the Midwestern and Rocky Mountain regions of the United States.  Our
communications services include local, long distance, Internet access, data,
voice mail and paging, all from a single company on a single bill.  We believe
we are the first communications provider in most 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 December 31, 1998, we served over 397,600 local
lines in 269 cities and towns.

     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 and paging services

     In most of our markets, we compete with the incumbent 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, Minnesota, South Dakota, North Dakota,
Colorado and Wyoming to carry additional communications traffic on our own
network.

     The following chronology highlights some of the important events in the
development of our business:


           Date                                     Event
- ---------------------------  ---------------------------------------------------
June 1991                    McLeodUSA was incorporated in Iowa as "McLeod
                             Telecommunications, Inc."

November 1992                McLeodUSA began operations, providing fiber optic
                             maintenance services for the Iowa Communications
                             Network. The Iowa Communications Network is a
                             fiber optic communications network that links many
                             of the State of Iowa's schools, libraries and
                             other public buildings.

August 1993                  McLeodUSA was reincorporated in the State of
                             Delaware.

December 1993                One of our wholly owned subsidiaries, McLeodUSA
                             Telecommunications Services, Inc., received
                             regulatory approvals in Iowa and Illinois to offer
                             local and long distance services.

January 1994                 McLeodUSA began providing local and long distance
                             services in Iowa and Illinois.

April 1995                   McLeodUSA acquired MWR Telecom, Inc., a
                             competitive access provider in Des Moines, Iowa.

June 1996                    McLeodUSA completed its initial public offering of
                             Class A common stock.

July 1996                    McLeodUSA acquired Ruffalo, Cody & Associates,
                             Inc., a telemarketing company.

September 1996               McLeodUSA acquired TelecomUSA Publishing Group,
                             Inc. (now known as McLeodUSA Media Group, Inc.), a
                             telephone directory company.

April and June 1997          The Federal Communications Commission awarded
                             McLeodUSA a total of 26 "D" and "E" block
                             frequency personal communications services ("PCS")
                             licenses for approximately $32.8 million.

May 1997                     McLeodUSA changed its name from "McLeod, Inc." to
                             "McLeodUSA Incorporated."

July 1997                    The FCC awarded McLeodUSA four wireless
                             communications services ("WCS") licenses.

September 1997               McLeodUSA acquired Consolidated Communications
                             Inc. ("CCI"), a diversified telecommunications
                             holding company offering a variety of
                             communications products and services, including
                             local exchange and long distance services and
                             telephone directory publishing.  As part of the
                             acquisition of CCI, McLeodUSA acquired one
                             additional "E" block frequency PCS license.


     As of the date hereof, we offer communications services to business and
residential customers in Iowa, Illinois, North Dakota, South Dakota, Wisconsin
and Colorado.  We also offer communications services to business customers in a
number of markets in Minnesota, Missouri, Indiana, and Wyoming.  Over the next
several years, depending on competitive and other factors, we intend to offer
communications services in Idaho, Montana, Nebraska and Utah.  We offer long
distance service in 48 states in the continental United States.

                                       2
<PAGE>
 
     Our 27 PCS licenses cover areas of Iowa, Illinois, Minnesota, Nebraska and
South Dakota, encompassing approximately 110,000 square miles and a population
of approximately 6.9 million.  We plan to offer PCS or other wireless services
as part of our communications services by building a wireless network, entering
into strategic acquisitions or alliances, or employing a combination of these
methods.  Our four WCS licenses cover the Major Economic Areas of Milwaukee,
Wisconsin, Minneapolis/St. Paul, Minnesota, Des Moines-Quad Cities,
Iowa/Illinois and Omaha, Nebraska.  We intend to use the frequency blocks
covered by these licenses to provide fixed services, such as wireless local
loop, Internet access or meter reading.  See "--Proposed Wireless Services," "--
Regulation" and "--Risk Factors--We May Not Succeed in Developing or Making a
Profit from Wireless Services."

     The statements in the foregoing paragraphs about our expansion plans and
proposed wireless services are forward-looking statements within the meaning of
the safe harbor provisions of the Private Securities Litigation Reform Act of
1995. These plans may be revised, and our actual geographic expansion and
services may differ materially from that indicated by our current plans, in each
case as a result of a variety of factors, including:

     .  the availability of financing and regulatory approvals
     .  the number of potential customers in a target market
     .  the existence of strategic alliances or relationships
     .  technological, regulatory or other developments in our business
     .  changes in the competitive climate in which we operate
     .  the emergence of future opportunities.

     Our principal executive offices are located at McLeodUSA Technology Park,
6400 C Street SW, P.O. Box 3177, Cedar Rapids, Iowa 52406-3177, and our main
phone number is (319) 364-0000.

Recent Transactions

     Acquisition of Talking Directories and Info America.  On February 10, 1999,
we acquired Talking Directories, Inc., a Michigan corporation, for an aggregate
of 2,556,390 shares of our Class A common stock.  In a related and concurrent
transaction, on February 10, 1999, we also acquired Info America Phone Books,
Inc., a Michigan corporation, for an aggregate of 1,203,007 shares of our Class
A common stock.  We also paid approximately $27 million of the outstanding
obligations of Talking Directories and Info America at the time of these
transactions.

     Talking Directories and Info America are related companies, headquartered
in Grand Rapids, Michigan, that together publish and distribute proprietary
"white page" and "yellow page" telephone directories primarily in Michigan and
northwestern Ohio. In 1998, Talking Directories and Info America collectively
published and distributed approximately 2.6 million copies of 19 telephone
directories. As of December 31, 1998, Talking Directories had 257 employees and
Info America had no employees.

     The Ovation Merger Agreement.  On January 7, 1999, we entered into an
Agreement and Plan of Merger with Ovation Communications, Inc., a Delaware
corporation, and several stockholders of Ovation by which Ovation will be merged
with and into a newly formed wholly owned subsidiary of McLeodUSA.  As a result
of the Ovation merger, (1) each share of Ovation's preferred stock will be
converted into the right to receive cash, and (2) each share of Ovation's common
stock will be converted, at the election of the stockholder, into the right to
receive cash or shares of our Class A common stock.  The amount of cash into
which each share of Ovation's preferred stock will be converted and the amount
of cash or number of shares of Class A common stock into which each share of
Ovation's common stock will be converted will be determined immediately before
completion of the Ovation merger based on formulas specified in the Ovation
merger agreement.  We estimate that we will be required to issue approximately
5.1 million shares of our Class A common stock and to pay approximately $141
million cash to effect the Ovation merger.  We will also assume approximately
$95 million in Ovation debt.  In addition, under the terms of the Ovation merger
agreement, each option to purchase Ovation common stock issued under Ovation's
stock option plan will become or be replaced by an option to purchase a number
of shares of our Class A common stock equal to the number of shares of Ovation
common stock that could have been 

                                       3
<PAGE>
 
purchased (assuming full vesting) under the Ovation stock option multiplied by
the exchange ratio used to convert Ovation common stock into Class A common
stock.

     Consummation of the Ovation merger is subject to the satisfaction of
several conditions.  Stockholders of Ovation holding in the aggregate
approximately 94% of the voting power attributable to Ovation's common stock and
preferred stock have agreed to vote all of their shares in favor of the Ovation
merger at a meeting of the stockholders of Ovation.

     In connection with the execution of the Ovation merger agreement, we
entered into a revolving credit agreement with Ovation by which we agreed to
lend Ovation up to $20 million on a senior subordinated unsecured basis.  In
addition, several Ovation stockholders agreed through December 31, 2001 to
restrictions on their ability to transfer the shares of Class A common stock
they will receive in the Ovation merger.  See "Security Ownership of Certain
Beneficial Owners and Management--Investor Agreement and Stockholders'
Agreements."

     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 cites in Michigan.  Ovation provides the following services:

     .  local and network access
      
     .  competitive local exchange
      
     .  incumbent local exchange
      
     .  long distance
      
     .  voice mail, teleconferencing and calling card

     .  Internet access

     As of December 31, 1998, Ovation served approximately 32,650 business local
lines and 12,900 residential local lines to approximately 2,900 business
customers and 11,750 residential customers in 135 cities and towns.  Ovation had
1998 revenues of $21.5 million, including revenues received between October 1,
1998 and December 31, 1998 as a result of Ovation's acquisition of BRE
Communications, L.L.C. d/b/a Phone Michigan on October 1, 1998.  As of December
31, 1998, Ovation had four switches, approximately 564 miles of fiber optic
communications network and 384 employees.

                                  ___________


     We have obtained information regarding Talking Directories, Info America
and Ovation from each of these companies, respectively.  Although we believe
this information is reliable, it has not been independently verified.  The
financial information about each of these companies is unaudited.

     Recent Financings. On February 22, 1999, we completed a private offering of
$500 million aggregate principal amount of our 8 1/8% senior notes due February
15, 2009, yielding net proceeds of approximately $487.8 million. The 8 1/8%
senior notes accrue interest at a rate of 8 1/8% per annum payable in cash semi-
annually in arrears on February 15 and August 15 of each year, starting August
15, 1999.

     As of December 31, 1998, we estimated, based on our business plan, capital
requirements and growth projections as of that date, our aggregate capital
requirements through 2001 would be $1.4 billion.  Our estimated aggregate
capital requirements include the projected cost of:

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

     .  expanding operations in existing and new markets
      
     .  developing wireless services
      
     .  funding general corporate purposes
      
     .  completing recent and pending acquisitions
      
     .  constructing, acquiring, developing or improving telecommunications
        assets

                                       4
<PAGE>
 
     The estimated costs and incremental capital needs associated with the
acquisitions of Talking Directories, Info America and Ovation are included in
our estimated aggregate capital requirements.

     We expect to use the following to address our capital needs:

     .  approximately $487.8 million in net proceeds from our offering of 8 1/8%
        senior notes

     .  approximately $591.7 million of cash and investments on hand at December
        31, 1998
     
     .  additional issuances of debt or equity securities
     
     .  projected operating cash flow

     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."

Business 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 reduce 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.

     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 local exchange carrier.

     Explore acquisitions and strategic alliances. We plan to pursue
     acquisitions, joint ventures 

                                       5
<PAGE>
 
     and strategic alliances to 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.

Market Potential

     The telecommunications industry is undergoing substantial changes due to
statutory, regulatory and technological developments.  We believe that we are
well-positioned to take advantage of these fundamental changes.

     Wireline Services.   The market for local exchange services consists of a
number of distinct service components, including:

     .    local network services, which generally include basic dial tone, local
          area charges, enhanced calling features and private line services
          (dedicated for a customer's use between locations)

     .    network access services, which consist of access provided by local
          exchange carriers to long distance communications network carriers

     .    short-haul long distance communications network services, which
          include intraLATA long distance calls and private lines

     .    other varied services, including operator services, Internet access,
          calling cards, publication of "white page" and "yellow page" telephone
          directories and the sale of business telephone equipment.

     Industry sources have estimated that the 1999 aggregate revenues of all
local exchange carriers will approximate $102 billion.  Until recently, there
was little competition in the local exchange markets, particularly for local
network and network access services.

     Before 1984, AT&T largely monopolized local and long distance telephone
services in the United States.  In 1984, as the result of a court decree, AT&T
was required to divest its local telephone systems (the "Divestiture"), which
created the present structure of the telecommunications industry in the U.S.
The Divestiture and subsequent related proceedings divided the country into 201
Local Access and Transport Areas ("LATAs").  As part of the Divestiture, AT&T's
former local telephone systems were organized into seven (now five, as a result
of industry consolidation) independent regional Bell operating companies.
Regional Bell operating companies were given the right to provide local
telephone service, local access service and intraLATA long distance service, but
were prohibited from providing interLATA service.  AT&T retained its long
distance services operations.  The separation of the regional Bell operating
companies from AT&T's long distance business created two distinct
telecommunications market segments: local exchange and long distance.  The
Divestiture decreed direct, open competition in the long distance segment, but
continued the regulated monopoly environment in local exchange services.

     Subsequently, several factors began to promote competition with respect to
local exchange services, including:

     .    growing customer demand for an alternative to the local exchange
          carrier monopoly, spurred partly by the development of competitive
          activities in the long distance market

     .    advances in the technology for transmission of voice, data and video
          requiring greater capacity and reliability levels than many local
          exchange carrier networks, which principally are copper-based, can
          accommodate

     .    the development of fiber optic and digital electronic technology,
          which reduced communications network construction costs while
          increasing transmission speeds, capacity

                                       6
<PAGE>
 
          and reliability compared to the older copper-based network typically
          employed by the existing local exchange carriers

     .    the significant access charges long distance carriers are required to
          pay to local exchange carriers to access the local exchange carriers'
          networks  

     .    statutory and regulatory initiatives in the telecommunications
          industry permitting and promoting competition in the local exchange
          market.

     Opportunities to compete in the local exchange market expanded
substantially on February 8, 1996, when the Telecommunications Act of 1996 was
enacted.  The Telecommunications Act of 1996 eliminated state legal prohibitions
against local exchange competition and requires incumbent local exchange
carriers to allow other providers of telecommunications services to purchase
elements of their local communications network offerings and to interconnect
with their communications facilities and equipment.  Most significantly, it
requires the incumbent local exchange carriers to complete local calls
originated by our customers and transferred or connected by us using our own
communications network facilities, and to deliver inbound local calls to us for
connection to our customers, assuring our customers of unimpaired local calling
ability.  In addition, local exchange carriers are obligated to provide local
number portability and dialing parity upon request and make their local services
available for resale by competitors.  Local exchange carriers also are required
to allow competitors non-discriminatory access to local exchange carrier poles,
conduit space and other rights-of-way.

     We believe that these requirements are likely, when fully implemented, to
increase competition among providers of local communications services and
simplify the process of switching from incumbent local exchange carrier services
to those offered by competitive local exchange carriers.  The Telecommunications
Act of 1996 also offers important benefits to the regional Bell operating
companies, however, such as the ability to provide interLATA long distance
services under specified conditions.  The process of implementing the
Telecommunications Act of 1996 is still incomplete, and important questions
remain unresolved.  See "--Regulation".

     A number of states have also taken regulatory and legislative action to
open local communications markets to various degrees of competition.  We expect
that continuing pro-competitive regulatory changes, together with increasing
customer demand, will create more opportunities for competitive service
providers to introduce additional services, expand their networks and address a
larger customer base.  However, we cannot assure you that government actions to
implement local telephone competition will be as complete or as timely as we
require to implement our business plans.

     Wireless Services. Demand for wireless communications has grown rapidly
over the past decade. According to the Cellular Telecommunications Industry
Association ("CTIA"), the number of wireless telephone subscribers nationwide
has grown from approximately 680,000 in 1986 to an estimated 61 million as of
June 30, 1998, with a compound annual growth rate of approximately 40% from
1990 through 1997. Wireless communication revenues for the 12-month period ended
June 30, 1998 are estimated by CTIA to have totaled over $29.6 billion, a 16%
increase over the prior 12-month period. We believe that the demand for wireless
communications will continue to grow dramatically, and that PCS will capture a
significant share of the wireless market, due to anticipated declines in costs
of service, increased function versatility, and increased awareness of the
productivity, convenience and safety benefits associated with such services. We
also believe the rapid growth of notebook computers and personal digital
assistants, combined with emerging software applications for wireless delivery
of electronic mail, fax and database searching, will further stimulate demand
for wireless service. In addition, we expect future competition between wireline
local exchange carriers and wireless service providers as "wireless local loop"
technology and reduced wireless rates facilitate migration of wireline minutes
to wireless carriers.

Current Products and Services

     We derive our revenue from:

     .    our core business of providing local, long distance and related
          communications services to end users, typically in a bundled package 

     .    the sale of advertising space in telephone directories

     .    traditional local telephone company services through the operation of
          Illinois Consolidated Telephone Company ("ICTC") in east central
          Illinois and Dakota Telecommunications Group, Inc. in 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
          and paging services

     For the year ended December 31, 1998, we derived 44% of our total revenues
from our core business of providing local, long distance and related
communications services, 24% from the sale of advertising space in telephone
directories, and 11% from traditional local telephone company services.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview."

     Integrated Communications Services.

     Overview.  As of December 31, 1998, we provided service, on a retail basis,
to over 397,000 local lines in our markets, primarily to small and medium sized
business customers and to residential customers.  Since beginning sales
activities in January 1994, we have increased our revenue from the sale of local
and long distance telecommunications services from $4.6 million for the year
ended December 31, 1994 to $267.4 million for the year ended December 31, 1998.

     In order to provide local communications services to most of our business
and residential customers in Iowa, Minnesota, North Dakota, South Dakota,
Colorado, Wisconsin, and Illinois, we purchase "Centrex" services through
various resale, interconnection and retail rate stability agreements with U S
WEST Communications, Inc. for our customers located in U S WEST's service
territories and Ameritech Corporation for most of our customers located in
Ameritech's service territories.  These "Centrex" agreements allow us to
partition part of the central office switching equipment serving the communities
in which we provide local services, which allows us to aggregate lines, have
control over several characteristics of those lines and provide a set of
standard features on them.  Our customers' telephone lines and numbers are
assigned to our portion of the switch.  U S WEST or Ameritech, as the case may
be, bills us for all the lines assigned to our customers and provides us with
call detail reports, which enable us to verify our customers' bills for both
local and long distance service.  These Centrex agreements protect us from
unilateral rate increases until 2002 or 2003, depending on the state.  We
believe that our Centrex-based local services are superior to a standard
business or residential telephone line, since we can offer features, such as
three-way calling, consultation hold and call transfer, at no extra charge.
Other custom calling features are available at additional cost.  Because we also
purchase the "Centrex Management System" and the "Centrex Mate Service" from U S
WEST and Ameritech, respectively, our personnel have on-line access to U S WEST
and Ameritech facilities and may make changes to the customers' services
electronically and quickly.

     In Missouri, we have an interconnection agreement with Southwestern Bell
Telephone Company that allows us to provide local service by leasing individual
lines and switches from Southwestern Bell for 

                                       8
<PAGE>
 
resale to our customers. This interconnection agreement provides for a wholesale
discount from the prevailing Southwestern Bell retail price, but does not allow
us to partition a portion of Southwestern Bell's switching equipment as with
Centrex services. As of the date hereof, we are renegotiating the terms of this
interconnection agreement with Southwestern Bell.

     In addition, in order to provide integrated communications services to many
of our business and residential customers in central Illinois and in the
Indianapolis, Indiana metropolitan area, we use our own switching equipment and
communications network facilities together with unbundled local "loop" elements
of Ameritech's telecommunications network that we purchase through
interconnection agreements.  In Cedar Rapids, Iowa and southeast South Dakota,
we also provide communications services to some of our business and residential
customers using only our own lines and communications network facilities.

     We provide most of our long distance service by purchasing communications
network capacity, in bulk, from national long distance carriers, and routing our
customers' long distance traffic over this capacity.  In some service areas, we
also carry long distance traffic on our own network facilities.

     Business Services.  End-user business customers can obtain local, long
distance and ancillary services, such as three-way calling and call transfer,
directly from us in each of the cities and towns in which we offer
communications services today.

     We generally offer business customers our integrated local communications
services at prices that are similar to the published retail rates for basic
business service provided by the incumbent local exchange carrier.  We offer our
business customers a flat rate or a negotiated rate for long distance service
consistent with their particular needs and within the guidelines of our filed
tariffs.  These rates are not subject to increase for the duration of the term
selected by the customer.  We also offer some of our business customers long
distance rates calculated by totaling their monthly calls and comparing the
total charges that would be applicable to such calls under different pricing
plans of the major long distance carriers.  The customer is then billed an
amount equal to the approximate lowest monthly charges among these plans, minus
any discount to which the customer may be entitled as a result of having made a
long-term commitment to use our services.

     Business customers previously served by CCI were on different long distance
rate plans.  We are transitioning these customers to our most appropriate rate
plan consistent with their needs.  Furthermore, in some states, including states
outside of our target markets, we offer business customers long distance service
only, in order to enhance our ability to attract business customers that have
offices outside of our target markets.

     Residential Services. We introduced our PrimeLine(R) service in 1996 and
now offer that service to residential and small business customers in various
cities and towns in Iowa, Illinois, North Dakota, South Dakota, Wisconsin,
Wyoming and Colorado. Our basic PrimeLine(R) service includes local and long
distance telephone service, as well as enhanced features such as three-way
calling, call transfer and consultation hold. Paging, voice mail, Internet
access and travel card services are also available at the customer's option as
part of our PrimeLine(R) service. We generally price our basic PrimeLine(R)
local service slightly higher than the rates for basic local service offered by
the incumbent local exchange carrier since our basic PrimeLine(R) local service
includes enhanced features that are not typically provided as part of the
incumbent local exchange carrier's basic local service. Our customers can add
paging, voice mail and Internet access services to their basic PrimeLine(R)
service at incremental rates designed to be no higher than separately purchasing
these services from other companies. We generally offer our PrimeLine(R)
customers a choice of either long distance rates that vary with the time of the
call or flat-rate long distance pricing applicable 24 hours a day, seven days a
week.

     Directory Services.  In 1998, we published 156 proprietary "white page" and
"yellow page" telephone directory titles and distributed approximately 14.2
million copies of these directories to local telephone subscribers in 21 states
in the Midwestern and Rocky Mountain regions of the United States, including
most of our target markets.  We also published 287 "white page" and "yellow
page" telephone directory titles for other companies and distributed
approximately 4 million copies of these directories to local telephone
subscribers in 38 states and the U.S. Virgin Islands.  Our telephone directory
services generated 1998 revenues of approximately $144.9 million, primarily from
the sale of advertising space in the directories.

                                       9
<PAGE>
 
     Many of our telephone directories serve as "direct mail" advertising
because they contain information on how to contact us and detailed product
descriptions and step-by-step instructions on the use of our telecommunications
products.  In addition, we believe that our directories' distinctive black-and-
yellow motif combined with the trade name McLeodUSA strengthens brand awareness
in our markets.  See "--Sales and Marketing."

     Traditional Local Telephone Services.  Through ICTC and Dakota
Telecommunications, we provide regulated incumbent local exchange telephone
service to subscribers in central Illinois and southeast South Dakota.

     ICTC operates in 37 exchanges, or service areas, the largest of which are
in Mattoon, Charleston, and Effingham, Illinois.  As of December 31, 1998, ICTC
had over 91,000 local access lines in its existing service areas.  ICTC offers a
broad range of local exchange services, including long distance carrier access
service, intraLATA toll service, local telephone service, local paging service,
national directory assistance, and equipment leasing.  Local telephone service
consists of furnishing a dial tone to local subscribers, at which time
subscribers can make a local call or a long distance call.  ICTC also offers
most of its local telephone subscribers custom calling features such as call
waiting, call forwarding, conference calling, speed dialing, caller
identification, and call blocking.  The rates for these and other local exchange
services are regulated by the Illinois Commerce Commission and the FCC.  To
provide these services, ICTC owns and operates three central office switches and
33 remote switches.

     As of December 31, 1998, Dakota Telecommunications served approximately
7,350 local service access lines in 13 telephone exchanges in southeastern South
Dakota.  Dakota Telecommunications provides a full range of communications
products and services, including local dial tone and enhanced services, local
private line and public telephone services, dedicated and switched data
transmission services, long distance telephone services, operator assisted
calling services, Internet access and related services.

     Special Access, Private Line and Data Services.  We provide, on a private
carrier basis, a wide range of special access, private line and data services to
our long distance carrier, wireless, cable television and other end-user
customers.  These services include:

     .    POP-to-POP special access

     .    end user/long distance carrier special access

     .    private line services

     POP-to-POP special access services provide telecommunications lines that
link the POPs of one long distance carrier or the POPs of different long
distance carriers in a market, allowing these POPs to exchange
telecommunications traffic for transport to final destinations.

     End user/long distance carrier special access services provide
telecommunications lines that connect an end user such as a large business to
the local POP of its selected long distance carrier.

     Long distance carrier special access services provide telecommunications
lines that link a long distance carrier POP to the local central office.  For
example, we have agreed to furnish long distance carrier special access services
to AT&T in up to 30 Midwestern cities in Illinois, Iowa, Minnesota, North Dakota
and South Dakota, providing a catalyst for the expansion of our intra-city
networks.

     Private line services provide telecommunications lines that connect various
locations of a customer's operation to transmit internal voice, video and/or
data traffic.  We provide private line services by using our own communications
network facilities, leasing communications network facilities from other
telecommunications carriers, or using some combination of owned and leased
communications network facilities

     Network Maintenance Services.  In 1990, the State of Iowa authorized
construction of the initial fiber optic links of the Iowa Communications Network
(the "Part I and II segments").  The Part I and II segments, which are owned by
the State of Iowa, provide 3,400 miles of fiber optic communications network
connections to approximately 139 sites in Iowa and are used primarily for
interactive distance 

                                       10
<PAGE>
 
learning, telemedicine and the State's own long distance telephone traffic. We
have entered into a fiber optic maintenance contract with the State of Iowa to
provide maintenance services for the Part I and II segments of the Iowa
Communications Network until 2004. Our maintenance activities under this
contract are performed on a 24-hour-per-day, 365-days-per-year basis, and
consist of alarm monitoring, repair services and cable location services.

     We believe that the expertise in fiber optic maintenance we have developed
through the maintenance of the Iowa Communications Network provides advantages
in maintaining our own communications network facilities.  Because commercial
use of the Part I and II segments is forbidden, however, neither McLeodUSA nor
any other communications carrier may use capacity on the Part I and II segments
to provide communications services to customers.

     Telephone Equipment Services.  We sell, lease, install and service
telephone systems, primarily to small and medium sized businesses in Iowa,
Illinois and Minnesota.  We believe these services provide valuable expertise
for and complement our communications services offerings, giving us additional
contact with the small and medium sized businesses we target in marketing our
communications services.

     Video Services.  We own 85% of Greene County Partners, Inc., a cable
television company that as of the date hereof provides cable television service
to approximately 16,800 subscribers in Illinois and Michigan.  Through Dakota
Telecommunications, we also own and operate 26 cable television systems located
in southeastern South Dakota, northwestern Iowa and southwestern Minnesota.  As
of December 31, 1998, these systems provided service to approximately 5,930
subscribers.

     We have also received a franchise from the city of Cedar Rapids, Iowa to
provide cable television service.  We are using this franchise to explore the
possible synergies between cable television and our advanced communications
services offerings, such as Integrated Services Digital Network ("ISDN"), low
and high speed Internet, video and other advanced services.  Depending on the
results of this preliminary initiative and on other factors, including
technological, regulatory or other developments in our business, changes in the
competitive climate in which we operate, and the emergence of future
opportunities, we may elect to offer cable service on an expanded basis in the
future.

     Telemarketing Services.  We provide direct marketing and telemarketing
services for third parties, as well as a variety of fund-raising services for
colleges, universities and other non-profit organizations throughout the United
States.  We believe that these services provide valuable marketing opportunities
and expertise for our communications services, particularly with respect to
potential residential customers.  In addition to providing telemarketing
services for third parties, we also use our telemarketing sales personnel for
sales of our PrimeLine(R) residential services.  See "--Sales and Marketing."

     Computer Networking Services.  Through Dakota Telecommunications, we
provide customized, integrated solutions for computing networks in some markets
in South Dakota.  Typical services include review of customer system
requirements; selection, design and planning of system components and networks;
and operating and network support services.

     Other Communications Services.  We provide pay telephone service, operator
services and paging services in some markets.  In addition, we own a minority
interest in a partnership that provides cellular service in central Illinois.

Expansion of Services Using Our Own Communications Network Facilities

     As of the date hereof, we are providing service to over 2,300 local lines
in Cedar Rapids, Iowa and southeast South Dakota using only our own switching
and fiber optic communications network facilities connected directly to our
customers' locations.  We are extending our intra-city fiber optic
communications network and switching capacity to enable us to provide expanded
services directly to our customers and reduce the expense of leasing
communications facilities from the existing telephone company.

     As of the date hereof, we are also offering service to over 7,000 local
lines located in central
                                       11
<PAGE>
 
Illinois and in Indianapolis, Indiana using our own switches and fiber optic
communications network facilities combined with network elements purchased from
Ameritech through interconnection agreements. We are building a state-of-the-art
fiber optic communications network to enable us to serve additional end-user
customers in this manner, using our communications network facilities in
combination with network elements of existing telephone companies. Our
communications network and switching capacity is also designed to serve other
wireline and wireless carriers on a wholesale basis.

     We have received state regulatory approval to offer local switched services
using our own communications network facilities in Colorado, Idaho, Iowa,
Illinois, Indiana, Minnesota, Missouri, Nebraska, North Dakota, South Dakota,
Utah, Wisconsin and Wyoming.  We intend to offer additional local switched
services using our own network facilities, either alone or in combination with
network elements purchased from existing telephone companies, in Des Moines,
Waterloo, Cedar Falls, Dubuque, Sioux City, Council Bluffs, and Iowa City, Iowa
and the Quad Cities of Iowa/Illinois (Davenport, Bettendorf, Rock Island and
Moline), among other places.  We then plan to expand these facilities-based
services to other cities as our communications network develops and our market
penetration increases.

     Our plans to provide local switched services using our own communications
network facilities will depend upon obtaining favorable interconnection
agreements and terms for leasing network elements from existing telephone
companies.  In August 1996, the FCC released a decision (the "Interconnection
Decision") implementing the interconnection portions of the Telecommunications
Act of 1996. The Interconnection Decision has been the subject of significant
legal dispute. In January 1999, the U.S. Supreme Court rejected challenges to
the Interconnection Decision and affirmed the authority of the FCC to establish
rules governing interconnection. We believe that additional disputes regarding
the Interconnection Decision and other related FCC actions are likely. 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. See "--Regulation."

     The foregoing statements are forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995 and where we actually
provide such services will depend on factors such as:

     .    the outcome of the judicial proceedings regarding the Interconnection
          Decision

     .    technological, regulatory or other developments in our business

     .    changes in the competitive climate in which we operate

     .    the emergence of future opportunities

     For a detailed description of the expansion of our fiber optic
communications network, see "--Network Facilities."

Proposed Wireless Services

     As of the date hereof, we do not offer wireless services, although we do
own a minority interest in a cellular telephone partnership serving parts of
east central Illinois.  In April and June 1997, the FCC awarded us a total of 26
"D" and "E" block frequency PCS licenses, each covering 10 MHz of radio
spectrum, and in September 1997 we acquired CCI and its "E" block frequency PCS
license, giving us a total of 27 PCS licenses in 25 markets covering areas of
Illinois, Iowa, Minnesota, Nebraska and South Dakota.  We paid approximately
$32.8 million for the 26 PCS licenses awarded to us by the FCC.  CCI paid the
FCC for its PCS license before we acquired CCI.  Our PCS licenses encompass
approximately 110,000 square miles and a population of approximately 6.9
million.  We plan to offer PCS or other wireless services as part of our
communications services by building a wireless network, entering into strategic
acquisitions or alliances, or employing a combination of these methods.

     PCS differs from traditional cellular telephone service principally in that
PCS systems operate at a higher frequency band and employ advanced digital
technology.  Compared to existing cellular service, these features are expected
to enable PCS system operators to offer customers lower cost service options,
lighter handsets with longer battery lives, and new and enhanced service
offerings.

                                       12
<PAGE>
 
     We will need to spend significant time and money to develop wireless
services.  To implement a wireless system, we will need to build or otherwise
acquire access to wireless infrastructure.  The infrastructure of a wireless
system generally consists of switches, base station transmitters and receivers,
and related equipment.  We may also incur costs related to site acquisition and
preparation, installation services, zoning approval or other permits, frequency
planning, construction and equipment procurement, installation and testing.
Furthermore, we believe that our ability to successfully offer wireless services
will depend on our ability to offer roaming service to our customers so they can
use their handsets outside our service area.  This will require us to establish
suitable roaming arrangements with other wireless operators in other markets
constructing systems compatible with our own.  We cannot predict when, or
whether, we will be able to enter into such roaming agreements with local
providers.

     We have entered into long-term agreements with our electric utility
stockholders (Alliant Energy Investments Inc. (collectively with its
predecessors and affiliates, "Alliant Energy"), and MHC Investment Company
(collectively with its predecessors and affiliates, "MidAmerican")) and with
Wisconsin Power and Light Company, Illinois Power Company and Illinois Central
Railroad Corporation, that will enable us to install base stations and other
equipment on such companies' towers.  See "--Network Facilities."  We expect the
use of these existing towers and other facilities occupied by other
telecommunications service providers and utility companies to facilitate our
development of wireless services.

     On July 21, 1997, the FCC also awarded us four WCS licenses covering
Milwaukee, Wisconsin, Minneapolis/St. Paul, Minnesota, Des Moines-Quad Cities,
Iowa/Illinois and Omaha, Nebraska.  We expect to use the frequency blocks
covered by such licenses to provide fixed services, such as wireless local loop,
Internet access or meter reading.

     As the wireline and wireless markets converge, we believe that we can
identify other opportunities to generate revenues from the wireless industry on
both a retail and a wholesale basis.  On a retail basis, we believe that we will
be able to enter into strategic arrangements with both cellular and PCS
companies on favorable economic terms to allow us to offer wireless services as
part of our integrated communications services offerings.  On a wholesale basis,
these opportunities may include (1) leasing tower sites to wireless providers,
(2) connecting or transferring wireless traffic through our communications
network facilities and (3) transporting wireless traffic using our fiber optic
communications network to interconnect wireless providers' cell sites or to
connect such sites to either our communications network facilities or to
communications network facilities of other providers of wireline services.  For
example, we have entered into agreements with five wireless companies to provide
access to several of the towers we control.

     The statements in the foregoing paragraphs about our plans to offer
wireless services are forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995.  These plans may be revised,
and our actual wireless services may differ materially from that indicated by
our current plans, in each case as a result of a variety of factors, including:

     .    the availability of financing and regulatory approvals

     .    the number of potential customers in a target market

     .    the existence of strategic alliances or relationships

     .    technological, regulatory or other developments in our business

     .    changes in the competitive climate in which we operate

     .    the emergence of future opportunities

Wireless Service" and "--Risk Factors--Competition in the Wireless
Telecommunications Industry Could Make it Harder for Us Successfully to Offer
Wireless Services."

Network Facilities

     As the incumbent local exchange carriers are compelled, by regulatory
changes and competitive forces, to unbundle their network components and to
permit resale of their network elements and products, we expect to be able to
provide our customers with a full range of communications services 

                                       13
<PAGE>
 
using a combination of our own communications network, the networks of the
incumbent local exchange carriers and the networks of other competitive
carriers.

     As of December 31, 1998, we owned approximately 7,100 route miles of fiber
optic communications network and expect to add approximately 2,000
additional route miles of fiber optic network during 1999.  We will decide
whether to begin construction of fiber optic network in a market based on
various economic factors, including:

     .    the number of our customers in a market

     .    the anticipated operating cost savings associated with such
          construction

     .    any strategic relationships with owners of existing infrastructure
          (e.g., utilities and cable operators)

     .    strategic acquisitions of providers of wireless services or owners of
          existing infrastructure

     We are installing backbone communications network facilities that form a
series of fiber optic "self-healing rings" and intra-city communications network
facilities that provide access directly to customer locations.  These
communications network facilities are intended to enable us to provide local and
long distance service using our own facilities in selected cities and towns in
Iowa, Illinois, Indiana, Wisconsin and Minnesota, and in Sioux Falls, South
Dakota.  Our communications networks are designed to support a wide range of
communications services, provide increased network reliability and reduce costs.
Our communications network consists of fiber optic cables, which typically
contain between 24 and 144 fiber strands, each of which is capable of providing
many telecommunications circuits.  A single pair of fibers on our network can
transmit 32,256 simultaneous voice conversations, whereas a typical pair of
copper wires can carry a maximum of 24 digitized simultaneous voice
conversations.  We expect that continuing developments in compression technology
and multiplexing equipment will increase the capacity of each fiber, providing
greater capacity at relatively low incremental cost.

     In 1995, the Iowa General Assembly passed legislation to extend the Iowa
Communications Network to 543 more endpoints (which are usually located in
schools or public libraries) throughout the State of Iowa (the "Part III
segments").  The majority of these fiber optic links, unlike the Part I and II
segments of the Iowa Communications Network, will be leased to the State of
Iowa, from a private entity, such as McLeodUSA.  As of December 31, 1998, we had
contracts to build and then lease capacity to the State of Iowa on 235 of such
segments.  Under our lease agreements with the State of Iowa, we are
constructing a "fiber-rich" broadband communications network on which the State
of Iowa has agreed to lease one DS-3 circuit for a period of seven years for a
total aggregate lease cost of approximately $27.0 million.  Upon completion of
installation of each segment, the leases provide that the State of Iowa will
make a one-time up-front lease payment to us for the capacity, with nominal
monthly lease payments thereafter.  At the end of a seven-year period, the
leases may be extended, upon terms to be mutually agreed upon.  During the term
of the leases, the State of Iowa may order additional DS-3 circuits at a
mutually agreed upon price.

     In September 1997, as a result of our acquisition of CCI, we acquired
approximately 900 route miles of fiber optic network facilities, parts of which
are currently connected to Ameritech unbundled network elements through an
interconnection agreement.  We believe that CCI's experience in serving end user
local lines under the interconnection agreement will substantially assist our
technical abilities in interconnection to the unbundled network elements of
incumbent local exchange carriers.

     In March 1999, as a result of our acquisition of Dakota Telecommunications,
we acquired approximately 290 additional route miles of fiber optic
communications network facilities.

     We have reached agreements with our electric utility stockholders
(MidAmerican and Alliant Energy) and with Wisconsin Power and Light Company,
Illinois Power and Illinois Central Railroad that allow us to make use of those
companies' rights-of-way, underground conduits, distribution poles, transmission
towers and building entrances in exchange for rights by such companies to use
capacity on our network.  These agreements give us access to rights-of-way in
parts of Iowa, Illinois and Wisconsin for installation of our wireline and
wireless networks.  We expect our access to these rights-of-way to have a
significant positive impact on our capital costs for network construction and
the speed with which we can 

                                       14
<PAGE>
 
construct our networks. We believe that our strategic relationships with our
electric utility stockholders and other companies that own rights-of-way and
infrastructure give us a competitive advantage.

Sales and Marketing

     Until June 1996, we directed our communications sales efforts primarily
toward small and medium sized businesses.  In June 1996, we began marketing our
PrimeLine(R) services to residential customers.

     Marketing of our integrated communications services to business customers
is conducted by direct sales personnel, located at our headquarters in Cedar
Rapids, Iowa and in branch sales offices in Iowa, Illinois, North Dakota, South
Dakota, Minnesota, Missouri, Wisconsin, Indiana, Colorado, Nebraska and Wyoming.
Sales activities in our branch sales offices are organized and managed by
region.

     Marketing of our integrated communications services to residential
customers is conducted by telemarketers.  The telemarketers emphasize the
PrimeLine(R) integrated package of communications services and its flat-rated
per minute pricing structure for long distance service.  We also use Ruffalo
Cody's information database to identify attractive sales opportunities and
pursue those opportunities through a variety of methods, including calls from
our telemarketing personnel.

     Our sales force is trained to emphasize our customer-focused sales and
service efforts, including our 24-hours-per-day, 365-days-per-year customer
service center.  Our employees answer customer service calls directly rather
than requiring customers to use an automated queried message system.  We believe
that our emphasis on a single point of contact for meeting our customer's
communications needs is very appealing to our current and prospective customers.
We have also developed and installed customer-focused software for providing
integrated communications services.  This software permits us to present our
customers with one fully integrated monthly billing statement for local, long
distance, 800, international, voice mail, paging, Internet access and travel
card services, and will permit us to include additional services, such as
wireless services, when available.  We believe that our customer-focused
software platform is an important element in the marketing of our communications
services and gives us a competitive advantage in the marketplace.

     We believe our strategic acquisitions have enhanced our sales and marketing
efforts and increased our penetration of existing markets.  We believe these
acquisitions will also help accelerate our entry into new markets.  For example,
we began publishing and distributing telephone directories as a result of
acquisitions.  We can use our proprietary telephone directories as direct mail
advertising simply by including detailed product descriptions and information
about our communications products in them.  We believe that these telephone
directories provide us with a long-term marketing presence in the millions of
households and businesses that receive them.  We also believe that combining our
directories' distinctive black-and-yellow motif with the trade name McLeodUSA
strengthens brand awareness in all of our markets.

     In 1998, we expanded our communications sales and marketing efforts
primarily by opening new branch sales offices in North Dakota, South Dakota,
Minnesota, Colorado, Missouri, Wisconsin and Wyoming and continuing to expand
our sales and marketing efforts in Iowa and Illinois.  Over the next several
years, depending on competitive and other factors, we also intend to begin sales
and marketing efforts in Montana, Idaho and Utah.  The foregoing statements are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995 and the results of our actual expansion efforts
may be materially different, depending on a variety of other factors, including:

     .    the availability of financing and regulatory approvals
     .    the number of potential customers in a target market
     .    the existence of strategic alliances or relationships
     .    technological, regulatory or other developments in our business
     .    changes in the competitive climate in which we operate
     .    the emergence of future opportunities 

                                       15

Competition

     Wireline Competition.   The communications services industry is highly
competitive. We face intense competition from local exchange carriers, including
the regional Bell operating companies (primarily U S WEST, Ameritech and
Southwestern Bell) and GTE, which currently dominate their respective local
telecommunications markets.  Our long distance services also compete with the
services of hundreds of other companies in the long distance marketplace.  AT&T,
MCI WorldCom and Sprint currently dominate the long distance market.  Our local
and long distance services also compete with the services of other competitive
local exchange carriers in some markets.  Other competitors may include cable
television companies, competitive access providers, microwave and satellite
carriers, wireless telecommunications providers, and private networks owned by
large end-users.  In addition, we compete with the regional Bell operating
companies and other local exchange carriers, numerous direct marketers and
telemarketers, equipment vendors and installers, and telecommunications
management companies with respect to portions of our business.  Many of our
existing and potential competitors have financial and other resources far
greater than our own.

     We believe that the distinction between the local and long distance markets
is eroding, and other competitors will begin to offer integrated communications
services similar to our own.  For example, each of AT&T, MCI WorldCom and Sprint
has begun to offer local telecommunications services using their own network
facilities, network elements obtained from incumbent local exchange carriers, or
the facilities of other parties.  AT&T has announced its plan to enter into
exclusive arrangements with cable operators to use their local network
facilities for telecommunications services.  These and other companies currently
hold state regulatory certificates to offer local and long distance service in
Iowa, Illinois and other states within our target markets.  We cannot assure you
that these firms, and others, will not enter the markets or target the small and
medium sized businesses where we focus our sales efforts.

     A continuing trend toward business combinations and strategic alliances in
the telecommunications industry may strengthen our competitors.  For example,
WorldCom acquired MCI in September 1998 and AT&T acquired Teleport
Communications Group Inc. in July 1998 and Tele-Communications, Inc. in March
1999.  In addition, merger plans have been announced by Southwestern Bell and
Ameritech and by Bell Atlantic and GTE.  U S WEST and  Ameritech also announced
in May 1998 that each had entered into a marketing arrangement with Qwest
Communications, a long distance company.  The FCC ruled that these marketing
arrangements violate the Telecommunications Act of 1996, but both U S WEST and
Ameritech have appealed this ruling.  In addition, Southwestern Bell and
Williams Communications, Inc., a long distance company, have announced a
strategic alliance to supply services to each other.  These or other alliances
or combinations between our competitors could put us at a significant
competitive disadvantage.

     We depend on incumbent local exchange carriers to provide access service
for the origination and termination of most of our toll long distance traffic
and interexchange private lines.  Historically, charges for such access service
made up a significant percentage of the overall cost of providing long distance
service.  The FCC and various states are considering changes to access charge
rate levels and related issues involving support for universal service and other
public policy objectives.  The impact of these changes on us and our competitors
is not yet clear.  We could be adversely affected if we do not experience access
cost reductions proportionally equivalent to those of our competitors, if our
competitors receive a disproportionate share of universal service revenues, or
if regulation of incumbent local exchange carriers' access services is reduced.
As long as new Internet-based competitors continue to be exempt from these
charges, they could enjoy a significant cost advantage in this area.

     We also depend on incumbent local exchange carriers to provide our local
telephone service through access to local communications network elements,
termination service or local central office switching, or through wholesale
purchase of the local telephone services of such carriers that we then resell to
end users.  Any successful effort by the incumbent local exchange carriers to
deny or substantially limit our access to their network elements or wholesale
services would have a material adverse effect on our ability to provide local
telephone services.  Although the Telecommunications Act of 1996 imposes
interconnection obligations on incumbent local exchange carriers, we cannot
assure you that we will be able to obtain access to their communications network
elements or services at rates, and on terms and conditions, that will permit us
to offer local services at rates that are both profitable and competitive.

                                       16
<PAGE>
 
     The Telecommunications Act of 1996 also provides the incumbent local
exchange carriers with new competitive opportunities.  For example, under the
Telecommunications Act of 1996, the regional Bell operating companies will, upon
the satisfaction of various conditions, be able to offer interLATA long distance
services to local telephone service customers in their regions.  The regional
Bell operating companies are actively engaged in proceedings and other
activities by which they are seeking to satisfy those conditions.  We believe
that we have advantages over the incumbent local exchange carriers in providing
our telecommunications services, including our management's prior experience in
the competitive telecommunications industry and our emphasis on marketing
(primarily using a direct sales force for sales to business customers and
telemarketing for sales to residential customers) and on responsive customer
service.  However, the regional Bell operating companies may be allowed to offer
interLATA long distance services before their local exchange markets are
completely open to competition.  Under such circumstances in particular,
additional competition from the incumbent local exchange carriers could have a
material adverse effect on our business, results of operations and financial
condition.

     Competition for local and special access telecommunications services is
based principally on price, quality, network reliability, customer service and
service features.  We believe that our management expertise and emphasis on
customer service allows us to compete effectively with the incumbent local
exchange carriers in providing these services.  In addition, our fiber optic
communications networks provide both diverse access routing and redundant
electronics, which design features are not widely deployed by the local exchange
carriers' networks.  However, if the incumbent local exchange carriers,
particularly the regional Bell operating companies, charge alternative providers
such as McLeodUSA unreasonably high fees for interconnection to their networks,
significantly lower their rates for access and private line services, or offer
significant volume and term discount pricing options to their customers, we
could be at a significant competitive disadvantage.

     In the future, an important element of providing competitive services may
be the ability to offer customers high-speed broadband local connections.  The
FCC is considering a proposal that would allow incumbent local exchange carriers
to offer these and other services through separate affiliates, in which case
their network elements for providing these services would not need to be made
available to us or other competitors.  AT&T has announced that it is entering
into arrangements with cable companies for the exclusive use of their local
networks for broadband telecommunications and several cable companies are
offering broadband Internet access over their network facilities.  As of the
date hereof, we offer such broadband local access to our customers only in
limited areas in Cedar Rapids, Iowa and southeast South Dakota.  If we are
unable to meet future demands of our customers for broadband local access or
other services on a timely basis at competitive rates, we may be at a
significant competitive disadvantage.

     For more information about the regulatory environment in which we operate,
see "--Regulation."

     Wireless Competition.   The wireless telecommunications industry is
experiencing significant technological change, as evidenced by the increasing
pace of improvements in the capacity and quality of digital technology, shorter
cycles for new products and enhancements, and changes in consumer preferences
and expectations.  We believe the market for wireless telecommunications
services is likely to expand significantly as equipment costs and service rates
continue to decline, equipment becomes more convenient and functional, wireless
services become more diverse, technology improves and new competitors enter the
market.  We also believe providers of wireless services increasingly will offer,
in addition to products that supplement a customer's wireline communications
like cellular telephone services in use today, wireline replacement products
that may result in wireless services becoming the customer's primary mode of
communication.  Accordingly, we expect competition in the wireless
telecommunications business to be dynamic and intense as a result of the
entrance of new competitors and the development of new technologies, products
and services.  We anticipate that in the future there could potentially be eight
wireless competitors in each of our proposed PCS markets: two existing cellular
providers, five other PCS providers and Nextel Communications Inc., an ESMR
provider.  There are over ten principal cellular providers and over 20 principal
PCS licensees in our proposed PCS markets.  In addition, we could face
competition from mobile satellite services which are under development.

     Competition with these or other providers of wireless telecommunications
services may be intense.  Many of our potential wireless competitors have
substantially greater financial, technical, marketing, sales, manufacturing and
distribution resources than our own and have significantly greater experience
than us in testing new or improved wireless telecommunications products and
services.  Some 

                                       17
<PAGE>
 
competitors, particularly WCS carriers, are expected to market other services,
such as cable television access, with their wireless telecommunications service
offerings. We do not currently offer wireless cable television access. In
addition, several of our potential wireless competitors are operating or
planning to operate, through joint ventures and affiliation arrangements,
wireless telecommunications systems that encompass most of the United States. We
cannot assure you that we will be able to compete successfully in this
environment or that new technologies and products that are more commercially
effective than our technologies and products will not be developed. See
"--Wireless Services."

Regulation

     Overview.   Our services are subject to federal, state and local
regulation.  The FCC exercises jurisdiction over our facilities and services to
the extent they are used to provide, originate or terminate interstate or
international common carrier communications.  State regulatory commissions
retain jurisdiction over the same facilities and services to the extent they are
used to originate or terminate intrastate common carrier communications.  Local
governments may require us to obtain licenses, permits or franchises regulating
use of public rights-of-way necessary to install and operate our networks.  In
addition, the licensing, construction, operation, sale and interconnection
arrangements of wireless telecommunications systems are regulated to varying
degrees by the FCC.  The construction and operation of wireless systems also may
be subject to state and local regulation.

     Through our subsidiaries, we hold various federal and state regulatory
authorizations.  We often join other industry members in seeking regulatory
reform at the federal and state levels to open additional telecommunications
markets to competition.

     Through our wholly owned subsidiary McLeodUSA Network Services, we provide
competitive access services as a private carrier on a non-regulated basis.  In
general, a private carrier is one that provides service to customers on an
individually negotiated contractual basis, as opposed to a common carrier that
provides service to the public on the basis of generally available rates, terms
and conditions.  We believe that McLeodUSA Network Services' private carrier
status is consistent with applicable federal and state laws, as well as
regulatory decisions interpreting and implementing those laws as of the date
hereof.  Should such laws and/or regulatory interpretations change in the future
to reclassify McLeodUSA Network Services' regulatory status, we believe that
compliance with such reclassification would not have a material adverse effect
on us.

     Through our wholly owned subsidiaries, we are also subject to federal and
state regulatory requirements, including, in some states, bonding requirements,
due to our direct marketing, telemarketing and fund-raising activities.

     Federal Regulation.   The FCC classifies us as a non-dominant carrier.  As
a non-dominant carrier, our interstate and international services are not
subject to material federal regulation, although we are required to file tariffs
with the FCC for our common carrier services.  The FCC also imposes prior
approval requirements on transfers of control and assignments of radio licenses
and operating authorizations.  The FCC has the authority to condition, modify,
cancel, terminate or revoke such licenses and authorizations for failure to
comply with federal laws or the rules, regulations and policies of the FCC.  The
FCC may also impose fines or other penalties for such violations.  While we
believe we are in compliance with applicable laws and regulations, we cannot
assure you that the FCC or third parties will not raise issues with regard to
our compliance.

     The FCC's role with respect to local telephone competition arises
principally from the Telecommunications Act of 1996, which became effective
February 8, 1996.  The Telecommunications Act of 1996 preempts state and local
laws to the extent that they prevent competitive entry into the provision of any
telecommunications service and gives the FCC jurisdiction over important issues
related to local competition.  However, state and local governments retain
authority over significant aspects of the provision of local telecommunications.
The Telecommunications Act of 1996 imposes a variety of new duties on local
exchange carriers, including non-incumbent local exchange carriers like
McLeodUSA, in order to promote competition in local exchange and access
services.  These duties include requirements to:

                                       18
<PAGE>
 
     .    complete calls originated by competing carriers on a reciprocal basis
     .    permit resale of services
     .    permit users to retain their telephone numbers when changing carriers
     .    provide competing carriers access to poles, ducts, conduits and
          rights-of- way at regulated prices

     Incumbent local exchange carriers are also subject to additional
requirements.  These duties include obligations of the incumbent local exchange
carriers to:

     .    interconnect their networks with competitors
     .    offer collocation of competitors' equipment at their premises
     .    make available elements of their networks (including network
          facilities, features and capabilities) on non-discriminatory,
          cost-based terms
     .    offer wholesale versions of their retail services for resale at
          discounted rates

     Collectively, these requirements recognize that local exchange competition
is dependent upon cost-based and non-discriminatory interconnection with and use
of incumbent local exchange carrier networks.  Failure to achieve such
interconnection arrangements could have an adverse impact on the ability of
McLeodUSA or other entities to provide competitive local exchange services.
Under the Telecommunications Act of 1996, incumbent local exchange carriers are
required to negotiate in good faith with carriers requesting any or all of the
above arrangements.  In addition, in the Interconnection Decision and related
actions the FCC has adopted more specific rules to implement these requirements.
The Interconnection Decision has been the subject of significant legal dispute.
In January 1999, the U.S. Supreme Court rejected challenges to the
Interconnection Decision and affirmed the authority of the FCC to establish
rules governing interconnection.  We believe that additional disputes regarding
the Interconnection Decision and other related FCC actions are likely.

     The Telecommunications Act of 1996 also eliminates previous prohibitions on
the provision of interLATA long distance services by the regional Bell operating
companies and the general telephone operating companies.  The regional Bell
operating companies are permitted to provide interLATA long distance service
outside those states in which they provide local exchange service ("out-of-
region long distance service") upon receipt of any necessary state and/or
federal regulatory approvals that are otherwise applicable to the provision of
intrastate and/or interstate long distance service.  Under the
Telecommunications Act of 1996, the regional Bell operating companies will be
allowed to provide long distance service within the regions in which they also
provide local exchange service ("in-region service") on a state-by-state basis
upon specific approval of the FCC and satisfaction of other conditions,
including a checklist of interconnection requirements intended to open local
telephone markets to competition.  As of the date hereof, the FCC has not found
that any regional Bell operating company has met these interconnection
requirements.  If the FCC does permit U S WEST, Ameritech or Southwestern Bell
to provide long distance service in their local service regions before they meet
our local interconnection needs, they would be able to offer integrated local
and long distance services and could have a significant competitive advantage in
marketing those services to their existing local customers.

     The Telecommunications Act of 1996 imposes restrictions on the regional
Bell operating companies in connection with their entry into the interLATA long
distance services market.  Among other things, for the first three years (unless
extended by the FCC) the regional Bell operating companies must pursue such
activities only through separate subsidiaries with separate books and records,
financing, management and employees.  In addition, affiliate transactions with
these subsidiaries must be conducted on a non-discriminatory basis.

     In the future, an important element of providing competitive services may
be the ability to offer customers high-speed broadband local connections.  The
FCC is considering a proposal that would allow incumbent local exchange carriers
to offer these and other services through separate affiliates, in which case
their network elements for providing these services would not need to be made
available to us or other competitors.  AT&T has announced that it is entering
into arrangements with cable companies for the exclusive use of their local
networks for broadband telecommunications and several cable companies are
offering broadband Internet access over their network facilities.  As of the
date hereof, we offer such broadband local access to our customers only in
limited areas in Cedar Rapids, Iowa and southeast South 

                                       19
<PAGE>
 
Dakota. If we are unable to meet future demands of our customers for broadband
local access or other services on a timely basis at competitive rates, we may be
at a significant competitive disadvantage.

     The FCC also regulates the interstate access rates charged by incumbent
local exchange carriers for the origination and termination of interstate long
distance traffic.  Those access rates make up a significant portion of the cost
of providing long distance service.  The FCC has implemented changes to its
interstate access rules that result in restructuring of the access charge system
and changes in access charge rate levels.  These and related actions may reduce
access rates, and hence the cost of providing long distance service, especially
to business customers.  The impact of these new changes will not be known until
they are fully implemented over the next several years.  In a related
proceeding, the FCC has adopted changes to the methodology by which access has
been used in part to subsidize universal telephone service and other public
policy goals.  Telecommunications providers like McLeodUSA will pay a fee
calculated as a percentage of their revenues to support these goals.  The full
implications of these changes also remain uncertain and subject to change.

     In addition, the FCC and the states are considering related questions
regarding the applicability of access charge and universal service fees to
Internet service providers.  Currently, Internet service providers are not
subject to these expenses.  Many incumbent local exchange carriers and other
parties have argued that this exemption unfairly advantages Internet service
providers, particularly when they provide data, voice or other services in
direct competition with conventional telecommunications.

     In connection with its interconnection decisions, the FCC has granted local
exchange carriers additional flexibility in pricing their interstate special and
switched access services on a central office specific basis.  Under this pricing
scheme, local exchange carriers may establish pricing zones based on access
traffic density and charge different prices for central offices in each zone.
We anticipate that the FCC will grant local exchange carriers increasing pricing
flexibility as the number of interconnection agreements and competitors
increases.  The potential impact of such pricing flexibility on McLeodUSA and
other competitors is unclear at this time.

     As of the date hereof, we do not offer PCS services, although we do own a
minority interest in a cellular telephone partnership serving parts of east
central Illinois.  In April and June 1997, the FCC awarded us a total of 26 "D"
and "E" block frequency PCS licenses and in September 1997 we acquired CCI and
its "E" block frequency PCS license, giving us a total of 27 PCS licenses in 25
markets covering areas of Iowa, Illinois, Minnesota, Nebraska and South Dakota.
We paid approximately $32.8 million for the 26 PCS licenses awarded to us by the
FCC.  Our PCS licenses encompass approximately 110,000 square miles and a
population of approximately 6.9 million.  In July 1997, the FCC also awarded us
four WCS licenses in the Major Economic Areas of Milwaukee, Wisconsin,
Minneapolis/St. Paul, Minnesota, Des Moines-Quad Cities, Iowa/Illinois and
Omaha, Nebraska.  We are evaluating proposed wireless systems and expect to
utilize our PCS licenses as part of a network or a strategic combination to add
PCS or other wireless services to our integrated communications services.  We
intend to use the frequency blocks covered by our WCS licenses to provide fixed
services such as wireless local loop, Internet access or meter reading.

     All PCS licenses are awarded for a ten-year period, at the end of which,
absent prior revocation or a violation of the FCC's rules by the licensee, they
will be renewed.  As a PCS licensee, we are subject to "build-out" requirements
which require that specified levels of service be available by specified times.
If we fail to meet these coverage requirements, we may be subject to forfeiture
of our PCS licenses.

     PCS licenses permit use of radio spectrum that may be currently occupied by
fixed microwave systems.  The existing licensees of such systems retain the
right to continue to operate their systems until 2005.  To secure a sufficient
amount of unencumbered spectrum to operate a PCS system efficiently, we may need
to relocate many of these existing licensees.  In an effort to balance the
competing interests of existing microwave users and newly authorized PCS
licensees, the FCC has adopted a transition plan to relocate such microwave
operators to other spectrum blocks.  This transition plan allows most microwave
users to operate in the PCS spectrum for a one-year voluntary negotiation period
and an additional one-year mandatory negotiation period.  For public safety
entities dedicating a majority of their system communications for police, fire
or emergency medical services operations, the voluntary negotiation period is
three years.  Parties unable to reach agreement within these time periods may
refer the matter to the FCC for resolution, but the existing microwave user is
permitted to continue its operations until final FCC 

                                       20
<PAGE>
 
resolution of the matter. We estimate that we would be required to pay to
relocate approximately 50 microwave links operated by 19 different microwave
licensees in order to develop a PCS system in our target wireless markets. In
addition, the FCC has imposed new universal service requirements on wireless
carriers, as well as new number portability and enhanced "911" obligations on
commercial mobile radio service providers including PCS carriers, which may
require us to invest in advanced technology over the next few years.

     Wireless systems are also subject to Federal Aviation Administration
regulations respecting the location, lighting and construction of transmitter
towers and antennas and may be subject to regulation under the National
Environmental Policy Act and the environmental regulations of the FCC.  Wireless
providers also must satisfy a variety of FCC requirements relating to technical
and reporting matters.  One such requirement is the coordination of proposed
frequency usage between adjacent systems.  In addition, the height and power of
base station transmitting facilities and the type of signals they emit must fall
within specified parameters.

     The Communications Act of 1934 requires the FCC's prior approval of the
assignment or transfer of control of a PCS or other radio license.  In addition,
the FCC has established transfer disclosure requirements that require licensees
who transfer control of or assign a PCS license within the first three years to
file associated contracts for sale, option agreements, management agreements or
other documents disclosing the total consideration that the applicant would
receive in return for the transfer or assignment of its license.  Non-
controlling interests in an entity that holds a PCS license or PCS system
generally may be bought or sold by U.S. companies or individuals without prior
FCC approval, but subsequent notice must be provided to the FCC.

     The Telecommunications Act of 1996 imposes restrictions on investment in
McLeodUSA by foreign persons or corporations arising from our ownership of
common carrier radio licenses.  However, these restrictions generally do not
apply to investment by nationals of member countries of the World Trade
Organization.  As of the date hereof, we have no knowledge of any ownership by
or affiliation with foreign persons or telecommunications carriers in violation
of the Communications Act or the FCC's rules.

     Through our wholly owned subsidiaries, we are also subject to rules
governing telemarketing that have been promulgated by both the FCC and the
Federal Trade Commission.  The FCC and FTC telemarketing rules prohibit
telemarketers from engaging in deceptive telemarketing practices and require
that telemarketers make specified disclosures.  For example, these telemarketing
rules:

     .    prohibit the use of autodialers that employ prerecorded voice messages
          without the prior express consent of the dialed party

     .    proscribe the facsimile transmission of unsolicited advertisements

     .    require telemarketers to disclose clear and conspicuous information
          concerning quality, cost and refunds to a customer before a customer
          makes a purchase

     .    require telemarketers to compile lists of individuals who desire not
          to be contacted

     .    limit telemarketers to calling residences between the hours of 8:00
          a.m. and 9:00 p.m.

     .    require telemarketers to explicitly identify the seller and state the
          purpose of the call

     .    prohibit product misrepresentations

     State Regulation.  We provide intrastate common carrier services and are
subject to various state laws and regulations.  Most public utility commissions
subject providers such as McLeodUSA to some form of certification requirement,
which requires providers to obtain authority from the state public utility
commission before initiating service.  In most states, including Iowa and
Illinois, we are also required to file tariffs setting forth the terms,
conditions and prices for services that are classified as intrastate.  We are
required to update or amend these tariffs when we adjust our rates or add new
products, and are subject to various reporting and record-keeping requirements
in these states.

     Many states also require prior approval for transfers of control of
certified carriers, corporate reorganizations, acquisitions of
telecommunications operations, assignment of carrier assets, carrier stock

                                       21
<PAGE>
 
offerings and incurrence by carriers of significant debt obligations.
Certificates of authority can generally be conditioned, modified, canceled,
terminated or revoked by state regulatory authorities for failure to comply with
state law or the rules, regulations and policies of state regulatory
authorities.  Fines or other penalties also may be imposed for such violations.
State utility commissions or third parties could raise issues with regard to our
compliance with applicable laws or regulations which could have a material
adverse effect on our business, results of operations and financial condition.

     We hold certificates of authority to resell the local services of the
regional Bell operating companies and to offer local services using our own
communications network facilities in incumbent regional Bell operating company
exchanges in Iowa, Illinois, Wisconsin, Minnesota, North Dakota, South Dakota,
Wyoming, Idaho, Indiana, Missouri, Nebraska and Utah.  We also hold certificates
of authority to resell the local services of the regional Bell operating
companies in Colorado and Montana.  We intend to seek regulatory approval to
provide resale and facilities-based services in all states within our target
markets when the economic terms of interconnection with the incumbent local
exchange company make the provision of local services using our own
communications network facilities cost-effective. See "-- Expansion of Services
Using Our Own Communications Network Facilities."  We are also authorized to
offer long distance service in all 48 states in the continental United States.
We have obtained authority to offer long distance service in such states,
including states outside our target markets, because we believe this capability
will enhance our ability to attract business customers that have offices outside
of our target markets.  We may also apply for authority to provide services in
non-regional Bell operating company exchanges in our target market states and
other states in the futures.  While we expect and intend to obtain the necessary
regulatory authority in each jurisdiction where we plan to operate, we cannot
assure you that each respective agency will grant our request for authority.

     The Telecommunications Act of 1996 preserves the ability of states to
impose reasonable terms and conditions on the provision of intrastate service
and other related regulatory requirements.  In the last several years, Iowa,
Illinois, Minnesota, Wisconsin, Wyoming and North Dakota have enacted broad
changes in their telecommunications laws that authorize the entry of competitive
local exchange carriers and provide for new regulations to promote competition
in local and other intrastate telecommunications services.  As a general matter,
we believe the states will play a key role in the development of local exchange
competition.  Consequently, we could face regulatory decisions that adversely
affect our ability to compete in particular states.

     States also regulate the intrastate carrier access services of the
incumbent local exchange carriers.  We are required to pay access charges to
originate and connect our intrastate long distance traffic.  We could be
adversely affected by high access charges, particularly to the extent that the
incumbent local exchange carriers do not incur the same level of costs with
respect to their own intrastate long distance services.  In a related
development, states also will be developing intrastate universal service charges
parallel to the interstate charges created by the FCC.  For example, some
incumbent local exchange carriers are proposing that states create funds that
would be supported by potentially large payments by firms such as McLeodUSA
based on their total intrastate revenues.  Another state regulatory issue that
could adversely affect our business is the approval by some state regulatory
agencies of extended local area calling for incumbent local exchange carriers,
converting otherwise competitive intrastate toll service to local service.
States also are or will be addressing various intraLATA dialing parity issues
that may affect competition.  Our business could be adversely affected by these
or other developments.

     We believe that, as the degree of intrastate competition increases, states
will offer the local exchange carriers increasing pricing flexibility.  This
flexibility may present the local exchange carriers with an opportunity to
subsidize services that compete with our services with revenues generated from
non-competitive services, allowing incumbent local exchange carriers to offer
competitive services at prices below the cost of providing the service.  We
cannot predict the extent to which this may occur or its impact on our business.

     ICTC is subject to rate of return regulation by the Illinois Commerce
Commission.  Under such regulation, ICTC is allowed to earn up to a fixed rate
of return on its equity.  In the event that the Illinois Commerce Commission
finds that ICTC has exceeded its authorized rate of return on equity, ICTC could
be required to lower its customer rates or make refunds.  While we believe ICTC
is earning less than its authorized rate of return, we cannot assure you that
the Illinois Commerce Commission will not, at some 

                                       22
<PAGE>
 
future date, find that ICTC has earned more than its authorized rate of return
or that such a finding would not have a material adverse effect on us.

     In addition, a substantial proportion of ICTC's and Dakota
Telecommunications' revenues are derived from access charges imposed on long
distance carriers.  Access charge rate structures and rate levels have been
modified by recent regulatory changes, and further changes are possible.  If
such revisions result in a reduction of ICTC's and Dakota Telecommunications'
revenues and gross margins, it could have a material adverse effect on us.

     Several of our subsidiaries also hold state and federal certificates and
FCC licenses in connection with the operation of wireless telecommunications
services and paging services.

     Through our wholly owned subsidiaries, we engage in various direct
marketing, telemarketing and fund-raising activities.  Most states have laws
that govern these activities.  In states that regulate such activities, several
types of restriction have been imposed, either singly or in combination,
including requirements to:

     .    register with state authorities
     .    post professional bonds
     .    file operational contracts with state authorities
     .    respect statutory waiting periods
     .    register employees with state authorities
     .    prohibit control over funds collected from such activities

     Local Government Authorizations.  We are required to obtain construction
permits and licenses or franchises to install and expand our fiber optic
communications networks using municipal rights-of-way.  Some municipalities
where we have installed or anticipate constructing networks are proposing and
enacting ordinances regulating use of rights-of-way and imposing various fees in
connection with such use.  In some instances we have negotiated interim
agreements to authorize installation of facilities pending resolution of the fee
issue.  In many markets, the local exchange carriers do not pay rights-of-way
fees or pay fees that are substantially less than the fees we are required to
pay.  To the extent that competitors do not pay the same level of fees as us, we
could be at a competitive disadvantage.  We must also negotiate and enter into
franchise agreements with local governments in order to operate our video
services networks.  We have franchises for our existing services, but will need
additional franchises in order to expand into additional markets.  If we fail to
receive necessary permits or franchise agreements on commercially reasonable
terms or are unable to obtain or maintain right-of-way authorization or license
agreements, we could be materially adversely affected.  If we lose a right-of-
way, we could be required to remove our facilities from the right-of-way or
abandon our network in place.

Risk Factors

     In connection with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, set forth below are cautionary statements
identifying important factors that could cause our actual results to differ
materially from those projected in any forward-looking statements made by or on
behalf of us, whether oral or written.  We wish to ensure that any forward-
looking statements are accompanied by meaningful cautionary statements in order
to maximize to the fullest extent possible the protections of the safe harbor
established in the Private Securities Litigation Reform Act of 1995.
Accordingly, any such statements are qualified in their entirety by reference
to, and are accompanied by, the following important factors that could cause our
actual results to differ materially from those projected in our forward-looking
statements.


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:

                                       23
<PAGE>
 
     .    market conditions in the industry
     .    announcements and actions by competitors
     .    low trading volume
     .    quarterly variations in operating results or growth rates
     .    changes in estimates by securities analysts
     .    regulatory and judicial actions
     .    general economic conditions

     See "Market for Registrants' Common Equity and Related Stockholder Matters
- --Price Range of Class A Common Stock."

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
     .    inability successfully to 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.

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
subscribers.  This has 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
harm 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 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

     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 shares 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, 1995, our net losses have been as follows:

                                       24
<PAGE>
 
                            Net Losses
                            ----------

                    Period              Amount       
                    ------              ------
                    1995           $  11.3 million
                    1996           $  22.3 million
                    1997           $  79.9 million
                    1998           $ 124.9 million


We expect to incur significant operating 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. Failure to generate or raise sufficient
funds may require us to delay or abandon some of our expansion plans or
expenditures, which could harm our business and competitive position.

     As of December 31, 1998, 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 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
     .    completing recent and pending 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, we may not be
able to expand our markets, operations, facilities, network and services through
acquisitions as we intend.  See "Managements' Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."

                                       25
<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 debt 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 December 31, 1998, we had $1.2 billion of long-term debt and $462.8
million of stockholders' equity.  We incurred an additional $500 million of
long-term debt on February 22, 1999.  As a result, we expect our fixed charges
to exceed our earnings for the foreseeable future.  See "Managements' Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."

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
     .    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.  See "Managements' Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources."

We Are Prohibited from Paying Dividends.

  We do not anticipate paying any dividends for the foreseeable future.  The
indentures governing our debt prohibit us from paying cash dividends.  You
should therefore not expect to receive dividends on shares of our Class A common
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.

                                       26
<PAGE>
 
     U S WEST, Ameritech and Southwestern Bell 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.

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 them.
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 harm 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 our 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.

     Our local and long distance services also compete with the services of
other communications services companies competing 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, microwave
and satellite carriers, wireless telecommunications providers, private networks
owned by large end-users, and telecommunications management companies.

                                       27
<PAGE>
 
     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 and could put us at a significant competitive disadvantage.

     For additional information, see "--Competition."

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.

     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

     See "--Proposed Wireless Services."

Competition in the Wireless Telecommunications Industry Could Make it Harder for
Us Successfully to 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.  See "--
Competition--Wireless Competition."

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.

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 

                                       28
<PAGE>
 
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 harm 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.  See "--Regulation--Local Government Authorizations."

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 provides 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
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 harm 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

For additional information, see "--Regulation."

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

     As of December 31, 1998, Alliant Energy, MidAmerican, 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 59.4% of our
outstanding Class A common stock. These stockholders can collectively control
management policy and all 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 significantly harmed.  See "Managements'
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Date Conversion."

Employees

     As of December 31, 1998, we employed a total of 5003 full-time employees
and 570 part-time employees.  We believe that our future success will depend on
our continued ability to attract and retain highly skilled and qualified
employees.  We believe that our relations with our employees are good.

Item 2.  Properties.

     We own or lease offices and space in a number of locations, primarily for
sales offices and network equipment installations.  In August 1996, we purchased
approximately 194 acres of farm land in southern Cedar Rapids, Iowa for the
development of an office complex, known as the McLeodUSA Technology Park.  We
have constructed our new headquarters buildings on this site, consisting of a
one-story, 160,000 square foot office building, a two-story, 320,000 square foot
office building which also houses some of our telephone switching and computer
equipment, and a 36,000 square foot maintenance building and warehouse.  The
total cost of the construction of our new headquarters buildings was
approximately $35.6 million.  We also purchased approximately 120 acres of
undeveloped land adjacent to the McLeodUSA Technology Park for a purchase price
of approximately $1.4 million in August 1997.  As a result of our acquisition of
CCI, we also own a 60,000 square foot office building in Mattoon, Illinois, as
well as other properties in central Illinois.  We also maintain 55,000 square
feet of office space at our former headquarters in Cedar Rapids, Iowa, under a
lease expiring in March 2001.  In addition, we own 88 acres of undeveloped farm
and forest land in southern Cedar Rapids, Iowa.

Item 3.  Legal Proceedings.

     We are not aware of any material litigation against McLeodUSA. We are
involved in numerous regulatory proceedings before various public utility
commissions and the FCC, particularly in connection with actions by the regional
Bell operating companies.  For example, on February 5, 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.  Under the
terms of these tariffs and other notices, U S WEST would permit us to use its
central office switches until April 2005, but would not allow us to expand to
new cities and would severely limit the number of new lines we could partition
onto U S WEST's switches in cities we serve.

     We have challenged, or are challenging, this action by U S WEST in many of
the states where we do business or plan to do business. We have succeeded in
blocking this action in Iowa, Minnesota, South Dakota, North Dakota and
Colorado, although U S WEST could take further legal action in some of these

                                       30
<PAGE>
 
states. In Montana, Nebraska and Idaho, however, similar challenges to this
action have not succeeded. In Wyoming and Utah, challenges to this action remain
pending.

     U S WEST has introduced other measures that may make it more difficult or
expensive for us to use Centrex service. In January 1997, U S WEST proposed
interconnection surcharges in several of the states in its service region. In
February 1997, we joined other parties in filing a petition with the FCC
objecting to this proposal based on our belief that it violates several
provisions of the Telecommunications Act of 1996. The matter remains pending
before the FCC and various state public utility commissions.

     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.

     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 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
integrated communications services in that jurisdiction, which could have a
material adverse effect on our business, results of operations and financial
condition.  See "Business--Risk Factors--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" and "Business--Risk Factors--
Actions by U S WEST May Make it More Difficult for Us to Offer Our
Communications Services."

Dividend Policy

     We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying dividends in the foreseeable future. Restrictions
contained in the indentures that govern the terms of our debt prohibit us from
paying dividends. Future dividends, 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 (including the indentures that govern the
terms of our debt) and such other factors as our board of directors may deem
relevant. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources."

Recent Sales of Unregistered Securities

     During 1998, we offered and sold the following equity securities that were
not registered under the Securities Act of 1933, as amended:

     (1) On April 24, 1998, we issued an aggregate of 70,508 shares of Class A
common stock and paid approximately $1 million to the stockholders of NewCom
Technologies, Inc. and NewCom OSP Services, Inc. (collectively, "NewCom") in

                                       32
<PAGE>
 
A common stock on The Nasdaq Stock Market at the time of the transaction and

A common stock on The Nasdaq Stock Market at the time of the transaction.

     Each issuance of securities described above was made in reliance upon the
exemption from registration provided by Section 4(2) of the Securities Act or
Regulation D promulgated thereunder for transactions by an issuer not involving
any public offering. The recipients of securities in each such transaction
represented their intention to acquire the securities for investment only and
not with a view to or for distribution in connection with such transactions. All
recipients had adequate access to information about us through their
relationship with us or through information about us made available to them.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

     The following discussion and analysis should be read together with our
consolidated financial statements and the notes thereto and the other financial
data appearing elsewhere in this Form 10-K.

Overview

     We derive our revenue from:

     .    our core business of providing local, long distance and related
          communications services to end users, typically in a bundled package

     .    the 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 and telephone equipment
          sales, leasing, service and installation

     .    telemarketing services

     .    other communications services, including video, computer networking,
          cellular, operator, payphone, mobile radio and paging services

     We began providing traditional local telephone company services and other
communications services as a result of our acquisition of CCI in September 1997,
telephone directory advertising as a result of our acquisition of TelecomUSA
Publishing in September 1996, and telemarketing services as a result of our
acquisition of Ruffalo Cody in July 1996.  The table set forth below summarizes
our percentage of revenues from these sources:

</TABLE>

     We began offering local and long distance services to business customers in
January 1994.  At the end of 1995, we began offering, on a test basis, long
distance services to residential customers.  In June 1996, we began marketing
and providing to residential customers in Cedar Rapids, Iowa and Iowa City, Iowa
an integrated package of communications services, marketed under the name
PrimeLine(R), that includes local and long distance service, voice mail,
Internet access and travel card services.  Since June 1996, we have expanded the
states in which we offer service to business customers to include Iowa,
Illinois, Indiana, Minnesota, Wisconsin, North Dakota, South Dakota, Colorado,
Missouri and Wyoming.  We also expanded our PrimeLine(R) service to additional
cities in Iowa and Illinois and began offering the service to customers in North
Dakota, South Dakota, Wisconsin, Wyoming and Colorado.  We plan to continue our
efforts to market and provide local, long distance and other communications
services to business customers and market our PrimeLine(R) service to
residential customers.

     Our principal operating expenses consist of cost of service; selling,
general and administrative expenses ("SG&A"); and depreciation and amortization.
Cost of service primarily includes local services purchased from regional Bell
operating companies, costs to terminate the long distance calls of our customers
through long distance carriers, costs of printing and distributing telephone
directories and costs 

                                       36
<PAGE>
 
associated with maintaining the Iowa Communications Network. The Iowa
Communications Network is a fiber optic communications network that links many
of the State of Iowa's schools, libraries and other public buildings. SG&A
consists of sales and marketing, customer service and administrative expenses,
including the costs associated with operating our communications network.
Depreciation and amortization include depreciation of our telecommunications
network and equipment; amortization of goodwill and other intangibles related to
our acquisitions, amortization expense related to the excess of estimated fair
market value in aggregate of options over the aggregate exercise price of such
options granted to some of our officers, other employees and directors; and
amortization of one-time installation costs associated with transferring
customers' local line service from the regional Bell operating companies to our
local telecommunications service.

     As we expand into new markets, both cost of service and SG&A will increase.
We expect to incur cost of service and SG&A expenses before achieving
significant revenues in new markets.  Fixed costs related to leasing of central
office facilities needed to provide telephone services must be incurred prior to
generating revenue in new markets, while significant levels of marketing
activity may be necessary in the new markets in order for us to build a customer
base large enough to generate sufficient revenue to offset such fixed costs and
marketing expenses.

     In January and February 1996, we granted options to purchase an aggregate
of 965,166 and 688,502 shares of our Class A common stock, respectively, at an
exercise price of $2.67 per share, to some of our directors, officers and other
employees.  The estimated fair market value of these options, in the aggregate,
at the date of grant was later determined to exceed the aggregate exercise price
by approximately $9.2 million.  Additionally, in September 1997, we granted
options to purchase an aggregate of 1,468,945 shares of our Class A common stock
at an exercise price of $24.50 to some employees of CCI.  The fair market value
of these options, in the aggregate, at the date of grant exceeded the aggregate
exercise price by approximately $15.8 million.  These amounts are being
amortized on a monthly basis over the four-year vesting period of the options.

     We have experienced operating losses since our inception as a result of
efforts to build our customer base, develop and construct our communications
network infrastructure, build our internal staffing, develop our systems and
expand into new markets.  We expect to continue to focus on increasing our
customer base and geographic coverage and bringing our customer base onto our
communications network.  Accordingly, we expect that our cost of service, SG&A
and capital expenditures will continue to increase significantly, all of which
may have a negative impact on operating results.

     In addition, our projected increases in capital expenditures will continue
to generate negative cash flows from construction activities during the next
several years while we install and expand our fiber optic communications network
and develop wireless services.  We may also be forced to change our pricing
policies to respond to a changing competitive environment, and we cannot assure
you that we will be able to maintain our operating margin.  We cannot assure you
that growth in our revenue or customer base will continue or that we will be
able to achieve or sustain profitability or positive cash flows.

     We have generated net operating losses since our inception and,
accordingly, have incurred no income tax expense.  We have reduced the net
deferred tax assets generated by these losses by a valuation allowance which
offsets the net deferred tax asset due to the uncertainty of realizing the
benefit of the tax loss carry forwards.  We will reduce the valuation allowance
when, based on the weight of available evidence, it is more likely than not that
some portion or all of the deferred tax assets will be realized.

Year Ended 1998 Compared with Year Ended 1997

     Total revenue increased from $267.9 million for the year ended December 31,
1997 to $604.1 million for the year ended December 31, 1998, representing an
increase of $336.2 million or 125%.  Revenue from the sale of local and long
distance communications services accounted for $157.4 million of this increase,
including $58.1 million contributed by CCI. Local exchange services generated by
ICTC increased by $51.7 million over 1997.  Private line and data revenues
accounted for $26.7 million of increased revenues over 1997, which was primarily
attributable to the acquisition of CCI.  Network maintenance and equipment
revenue increased $11.9 million over 1997 due primarily to the acquisitions of
Digital Communications of Iowa, Inc., ESI Communications, Inc., CCI and NewCom.
Other 

                                       37
<PAGE>
 
communications revenue, which was due almost entirely to the acquisition
of CCI, represented $17.9 million of the increase in revenues.  Directory
revenues increased $63.8 million from 1997 to 1998 due to revenues from new
directories acquired in 1998 and the acquisition of CCI.  The $6.8 million
increase in telemarketing revenues from 1997 to 1998 was due almost entirely to
the acquisition of CCI.

     Cost of service increased from $151.2 million for 1997 to $323.2 million
for 1998, representing an increase of $172.0 million or 114%.  This increase in
cost of service was due primarily to the growth in our local and long distance
communications services and to the acquisitions of Digital Communications, ESI
Communications, CCI, CCC and NewCom, which contributed an aggregate of 
$109.7 million to the increase. Cost of service as a percentage of revenue
decreased from 56% for 1997 to 53% for 1998, as a result of these acquisitions
and as a result of reductions in the cost of providing local and long distance
services as a percentage of local and long distance communications revenue,
which decreased from 84% in 1997 to 70% in 1998. This decrease was primarily due
to the realization of benefits associated with new wholesale line cost rate
agreements with the regional Bell operating companies and reduced long distance
costs resulting from migration of over 60% of customer long distance traffic to
our fiber optic communications network.


     SG&A increased from $148.2 million for the year ended December 31, 1997 
to $260.9 million for the year ended December 31, 1998, an increase of 
$112.7 million or 76%. The acquisitions of Digital Communications, ESI
Communications, CCI, CCC, NewCom and Inlet contributed an aggregate of 
$61.9 million to the increase. Also contributing to this increase were increased
costs of $50.8 million primarily related to expansion of selling, customer
support and administration activities to support our growth.

     Depreciation and amortization expenses increased from $33.3 million for the
year ended December 31, 1997 to $89.1 million for the year ended December 31,
1998, representing an increase of $55.8 million or 168%. This increase consisted
of $38.1 million related to the acquisitions of Digital Communications, ESI
Communications, CCI, CCC, NewCom and Inlet, and $17.7 million due primarily to
the growth of our communications network.

     Other operating expenses represented the amortization of capitalized costs
associated with CCD directories in progress at the time we acquired CCI.

     Interest income increased from $22.7 million for the year ended December
31, 1997, to $26 million in 1998. This increase resulted from increased earnings
on investments made with the remaining proceeds from our debt offerings in March
and July 1997 and the proceeds from our offerings of 8 3/8% senior notes and 
9 1/2% senior notes in March and October 1998, respectively.

     Gross interest expense increased from $39.0 million for the year ended
December 31, 1997 to $88.9 million in 1998. This increase was primarily a result
of an increase in the accretion of interest on our 10 1/2% senior discount notes
of $8.4 million and an increase of interest of $36 million as the result of the
issuance of our 9 1/4% senior notes, 8 3/8% senior notes and 9 1/2% senior
notes. Interest expense of approximately $8 million and $4.4 million was
capitalized as part of our construction of fiber optic communications network
during 1998 and 1997, respectively. In addition, interest expense of
approximately $2.6 million was capitalized as part of our operating facilities
building construction and our software development in 1998, with no
corresponding amount in 1997.


     Net loss increased from $79.9 million for the year ended December 31, 
1997 to $124.9 million for the year ended December 31, 1998, an increase of
$45 million. This increase resulted primarily from the following three factors:

     .    the expansion of our local and long distance services, which requires
          significant expenditures, a substantial portion of which is incurred
          before the realization of revenues

     .    the increased depreciation expense related to the construction and
          expansion of our communications networks and amortization of
          intangibles related to acquisitions

                                       38

     .    net interest expense on indebtedness to fund market expansion, network
          development and acquisitions 

Year Ended 1997 Compared with Year Ended 1996

     Revenue was $267.9 million for the year ended December 31, 1997, an
increase of $186.6 million or 229% from $81.3 million for 1996.  This increase
was due to the many acquisitions completed in 1997 and 1996 as well as the
increase in local and long distance customers.  Revenue from the sale of local
and long distance communications services accounted for $68.6 million of the
increase, including $23.1 million contributed by CCI from September 25, 1997 to
December 31, 1997.  Local exchange services represented $16.1 million for the
period from September 25, 1997 to December 31, 1997, for which there were no
corresponding 1996 revenues.  Private line and data revenues accounted for 
$6.9 million of increased revenues over 1996 which was primarily attributable to
the acquisition of CCI. Network maintenance and equipment revenue increased
$15.0 million over 1996 due to the acquisitions of Digital Communications, ESI
Communications and CCI. Other communications revenue, which was due entirely to
the acquisition of CCI, represented $9.9 million of 1997 revenues with no
corresponding 1996 amount. Directory revenues increased $65.9 million from 1996
to 1997 and were due to a full year of TelecomUSA Publishing revenues in 1997
and the acquisition of CCI on September 24, 1997. The increase in telemarketing
revenues from 1996 to 1997 of $4.1 million was due almost entirely to the
acquisition of CCI.

     Cost of service increased from $52.6 million for the year ended 
December 31, 1996 to $151.2 million for the year ended December 31, 1997,
representing an increase of $98.6 million or 187%. This increase in cost of
service was due primarily to the growth in our local and long distance
communications services and to the acquisitions of Ruffalo Cody, TelecomUSA
Publishing, Digital Communications, ESI Communications and CCI, which
contributed an aggregate of $62.2 million to the increase. Cost of service as a
percentage of revenue decreased from 65% for the year ended December 31, 1996 to
58% for the year ended December 31, 1997, primarily as a result of the effect of
these acquisitions. The cost of providing local and long distance services as a
percentage of local and long distance communications revenue increased from 70%
for the year ended December 31, 1996 to 73% for the year ended December 31,
1997, primarily as a result of increased line costs associated with our
accelerated expansion into new markets.

     SG&A increased from $46 million for the year ended December 31, 1996 to
$148.2 million for the year ended December 31, 1997, an increase of 
$102.2 million or 222%. The acquisitions of Ruffalo Cody, TelecomUSA Publishing,
Digital Communications, ESI Communications and CCI contributed an aggregate of
$54.3 million to the increase. Also contributing to this increase were increased
costs of $43.6 million primarily related to expansion of selling, customer
support and administration activities to support our growth.

     Depreciation and amortization expenses increased from $8.5 million for the
year ended December 31, 1996 to $33.3 million for the year ended December 31,
1997, representing an increase of $24.8 million or 292%.  The increase was
primarily due to $14.3 million related to the acquisitions of Ruffalo Cody,
TelecomUSA Publishing, Digital Communications, ESI Communications and CCI, and
$3.8 million due primarily to the growth of our network in 1997.

     Other operating expenses in 1997 represented the realization of a purchase
accounting adjustment related to the capitalization of costs associated with
TelecomUSA Publishing and CCI directories in progress at the time of the
acquisitions.

     Interest income increased from $6 million for the year ended December 31,
1996 to $22.7 million for the year ended December 31, 1997.  This increase
resulted from increased earnings on investments made with a portion of the
proceeds from our offerings of Class A common stock in June and November 1996
and from our private offerings of 10 1/2% senior discount notes and 9 1/4%
senior notes in March 1997 and July 1997, respectively.

     Gross interest expense increased from $869,000 for the year ended 
December 31, 1996 to $39.0 million for the year ended December 31, 1997. This
increase was primarily a result of accretion of

                                       39
<PAGE>
 
interest on the 10 1/2% senior discount notes of $26.8 million and accrual of
interest on the 9 1/4% senior notes of $9.5 million. Interest expense of
approximately $4.4 million and $204,000 was capitalized as part of our
construction of fiber optic network during the years ended December 31, 1997 
and 1996, respectively.

     Net loss increased from $22.3 million for the year ended December 31, 
1996 to $79.9 million for the year ended December 31, 1997, an increase of 
$57.6 million. This increase resulted primarily from the following three
factors:

     .    the construction and expansion of our communications network which
          require significant expenditures, a substantial portion of which is
          incurred before the realization of revenues

     .    the increased depreciation expense related to those networks and
          amortization of intangibles related to acquisitions 

     .    net interest expense on indebtedness to fund market expansion, network
          development and acquisitions

     Operating loss before depreciation, amortization and other non-recurring
operating expenses increased from a negative $17.3 million for the year ended
December 31, 1996 to a negative $31.5 million for the year ended December 31,
1997, an increase of $14.2 million.  The change reflected the increase in the
operating loss incurred in 1997 due primarily to the expansion of our local,
long distance and other communications services as described above.

Year Ended 1996 Compared with Year Ended 1995

     Revenue increased from $29 million for the year ended December 31, 1995 to
$81.3 million for the year ended December 31, 1996, representing an increase of
$52.3 million or 180%.  Revenue from the sale of local and long distance
communications services accounted for $19.9 million of this increase.  Included
in the year ended December 31, 1996 revenue was $8.6 million of revenue from
Ruffalo Cody, which was acquired on July 15, 1996, and $15.1 million in revenue
from TelecomUSA Publishing, which was acquired on September 20, 1996.  Excluding
these acquisitions, 1996 revenue would have been $57.6 million.

     Cost of service increased from $19.7 million for the year ended 
December 31, 1995 to $52.6 million for the year ended December 31, 1996, an
increase of $32.9 million or 168%. This increase in cost of service was due
primarily to the growth in our local and long distance communications services
and to the acquisitions of Ruffalo Cody and TelecomUSA Publishing, which
contributed $4.5 million and $6.7 million, respectively, to the increase. Cost
of service as a percentage of revenue decreased from 68% to 65%, primarily as a
result of the effect of these acquisitions. The cost of providing local and long
distance services as a percentage of local and long distance communications
revenue increased from 68% for the year ended December 31, 1995 to 70% for the
year ended December 31, 1996, primarily as a result of an increased number of
higher volume, price-sensitive customers and increased local line costs
associated with expansion into new markets.

     SG&A increased from $18.1 million for the year ended December 31, 1995 to
$46 million for the year ended December 31, 1996, an increase of $27.9 million
or 155%.  The acquisitions of Ruffalo Cody and TelecomUSA Publishing contributed
$3.3 million and $7.3 million, respectively, to the increase.  Increased costs
of $17.3 million related to expansion of selling, customer support and
administration activities to support our growth also contributed to this
increase.

     Depreciation and amortization expenses increased from $1.8 million for the
year ended December 31, 1995 to $8.5 million for the year ended December 31,
1996, an increase of $6.7 million or 362%.  This increase consisted of 
$2.1 million related to the acquisitions of Ruffalo Cody and TelecomUSA
Publishing; amortization expense of $2 million related to the excess of
estimated aggregate fair market value of options over the aggregate exercise
price of such options granted to some of our officers, other employees, and
directors; and $2.6 million due primarily to the growth of our network in 1996.

                                       40
<PAGE>
 
     Other operating expense in 1996 represented the realization of a purchase
accounting adjustment related to the capitalization of costs associated with
directories in progress at the time we acquired TelecomUSA Publishing.

     We had net interest income of $5.4 million for the year ended December 31,
1996 compared to net interest expense of $771,000 for the year ended 
December 31, 1995 as a result of earnings on investments made with a portion of
the proceeds of our public offerings of Class A common stock during 1996 and
decreased interest expense on reduced borrowings as a result of our repayment of
all amounts outstanding under a bank credit facility maintained by McLeodUSA
from May 1994 until June 1996 with a portion of the net proceeds from our
initial public offering of Class A common stock. We also had other non-operating
income of $495,000 for the year ended December 31, 1996.

     Net loss increased from $11.3 million for the year ended December 31, 
1995 to $22.3 million for the year ended December 31, 1996, an increase of 
$11 million. This increase resulted primarily from the expansion of the local
and long distance businesses, amortization and other operating expenses related
to the acquisitions of Ruffalo Cody and TelecomUSA Publishing and amortization
expense related to stock options granted to some of our officers, other
employees and directors. The development of our business and the construction
and expansion of our communications network require significant expenditures, a
substantial portion of which is incurred before the realization of revenues.

     Operating loss before depreciation, amortization and other non-recurring
operating expenses increased from a negative $8.7 million for the year ended
December 31, 1995 to a negative $17.3 million for the year ended December 31,
1996, an increase of $8.6 million.  The change reflected the increase in the
operating loss incurred in 1996 due primarily to the expansion of our local,
long distance and other communications services and the factors described above.

Liquidity and Capital Resources

     Our total assets increased from $1.3 billion at December 31, 1997 to $1.9
billion at December 31, 1998, primarily due to the net proceeds of approximately
$583.8 million from our private offerings of 8 3/8% senior notes and 9 1/2%
senior notes in March 1998 and October 1998, respectively. At December 31, 1998,
our current assets of $793.2 million exceeded our current liabilities of $180.0
million, providing working capital of $613.2 million, which represents an
increase of $234.6 million compared to December 31, 1997, primarily attributable
to the net proceeds from our private offerings of 8 3/8% senior notes and 9 1/2%
senior notes. At December 31, 1997, our current assets of $517.9 million
exceeded current liabilities of $139.3 million, providing working capital of
$378.6 million.

     Net cash used in operating activities totaled $22.5 million for the year
ended December 31, 1998 and $8.8 million for the year ended December 31, 1997.
During the year ended December 31, 1998, cash for operating activities was used
primarily to fund our net loss of $124.9 million for such period.  As a result
of the expansion of our local and long distance communications services, we also
required cash to fund:

     .    growth in trade receivables of $6.4 million

     .    growth in inventory of $8.2 million

     .    prepaid and other expenses of $34.3 million

     .    deferred line installation costs of $13.6 million

These amounts were partially offset by:

     .    increases in accounts payable and accrued expenses of $32.2 million

     .    increases in deferred revenue of $4.6 million

     .    increases in customer deposits of $4.1 million

     .    cumulative non-cash expenses of $123.2 million

     During the year ended December 31, 1997, cash for operating activities was
used primarily to fund our net loss of $79.9 million for such period.  We also
required cash to fund the growth in accounts receivable and deferred line
installation costs of $15.9 million and $9.7 million, respectively, offset by

                                       41

increases in accounts payable and accrued expenses of $27.1 million, deferred
revenues of $7.2 million, customer deposits of $3 million and cumulative non-
cash expenses of $60 million.

     Net cash used in investing activities totaled $424.0 million during the
year ended December 31, 1998 and $242.8 million during the year ended 
December 31, 1997. The expansion of our local and long distance communications
services, development and construction of our fiber optic communications
networks and other capital expenditures resulted in purchases of equipment and
fiber optic cable and other property and equipment totaling $289.9 million and
$151.3 million during the years ended December 31, 1998 and 1997, respectively.
We also used cash of $607.4 million to acquire available-for-sale securities
during the year ended December 31, 1998, offset by proceeds from sales and
maturities of available-for-sale securities of $506.4 million during the period.
During the year ended December 31, 1997, the cash used in investing activities
was partially offset by net proceeds of $120.2 million from the sales and
maturities of available-for-sale securities.

     During the year ended December 31, 1998, we used an aggregate of 
$27.8 million cash to acquire:


     .    directories from F.D.S.D. Rapid City Directories, Inc. in March 1998

     .    directories from Bi-Rite Directories, Inc. in March 1998

     .    directories from Smart Pages, Inc. and Yellow Pages Publishers, Inc.
          in September 1997

     .    the capital stock of CCI in September 1997


     In 1997, the FCC awarded us 26 "D" and "E" block frequency PCS licenses and
in September 1997 we acquired CCI and its "E" block frequency PCS license,
giving us a total of 27 PCS licenses in 25 markets covering areas of Iowa,
Illinois, Minnesota, Nebraska and South Dakota.  During 1996 and 1997, we paid
an aggregate of approximately $32.8 million for the 26 PCS licenses awarded to
us by the FCC.

     Net cash received from financing activities was $569.6 million during the
year ended December 31, 1998, primarily as a result of our private offerings of
8 3/8% senior notes in March 1998 and 9 1/2% senior notes in October 1998. Net
cash received from financing activities during the year ended December 31, 1997
was $487 million and was primarily obtained from our private offerings of 10
1/2% senior discount notes in March 1997 and 9 1/4% senior notes in July 1997.

     1998 Financings. On March 16, 1998, we completed a private offering of $300

"Change of Control Payment Date" (as defined in the indenture governing the 8
3/8% senior notes). The 8 3/8% senior notes will mature on March 15, 2008.

     On October 30, 1998, we completed a private offering of $300 million
aggregate principal amount of our 9 1/2% senior notes in which we received net

maturity, plus accrued and unpaid interest, on or after November 1, 2008. In the
event of specified equity investments in McLeodUSA by specified strategic
investors on or before November 1, 2001, we may, at our option, use all or a
portion of the net proceeds from such sale to redeem up to 33 1/3% of the
original principal amount of the 9 1/2% senior notes at a redemption price equal
to 111.5% of their principal amount plus accrued and unpaid interest, if any, to

a purchase price equal to 101% of the principal amount of the 9 1/2% senior
notes tendered by such holder plus accrued and unpaid interest, if any, to any
"Change of Control Payment Date" (as defined in the indenture governing the 9
1/2% senior notes). The 9 1/2% senior notes will mature on November 1, 2008.

     1997 Financings. On March 4, 1997, we completed a private offering of $500
million aggregate principal amount at maturity of our 10 1/2% senior discount
notes. The 10 1/2% senior discount notes were issued with an original issue
discount in which we received approximately $288.9 million in net proceeds. The
10 1/2% senior discount notes accrete from March 4, 1997 at a rate of 10 1/2%
per year, compounded semi-annually to an aggregate principal amount of $500
million by March 1, 2002. As of December 31, 1998, the accreted balance of the
10 1/2% senior discount notes was $361.9 million. Interest will not accrue on
the 10 1/2% senior discount notes before March 1, 2002. Thereafter, interest
will accrue at a rate of 10 1/2% per annum and will be payable in cash semi-
annually in arrears on March 1 and September 1 of each year, starting September
1, 2002. The 10 1/2% senior discount notes are redeemable, at our option, in
whole or in part, at any time on or after March 1, 2002, at 105.25% of their
principal amount at maturity, plus accrued and unpaid interest, declining to
100% of their principal amount at maturity, plus accrued and unpaid interest, on
or after March 1, 2005. In the event of specified equity investments in

at our option, use all or a portion of the net proceeds therefrom to redeem up
to a maximum of 33 1/3% of the original principal amount of the 10 1/2% senior
discount notes at a redemption price of 110.5% of their accreted value, provided
that at least 66 2/3% of the original principal amount of the 10 1/2% senior
discount notes would remain outstanding after giving effect to such redemption.
In addition, in the event of a "Change of Control" (as defined in the indenture
governing the 10 1/2% senior discount notes) of McLeodUSA, each holder of 10
1/2% senior discount notes will have the right to require us to repurchase all
or any part of such holder's 10 1/2% senior discount notes at a purchase price
equal to 101% of the accreted value thereof prior to March 1, 2002, or 101% of
the principal amount thereof plus accrued and unpaid interest, if any, on or
after March 1, 2002. The 10 1/2% senior discount notes will mature on March 1,
2007.

     On July 21, 1997, we completed a private offering of $225 million aggregate
principal amount of our 9 1/4% senior notes in which we received net proceeds of
approximately $217.6 million.  Interest on the 9 1/4% senior notes accrues at
the rate of 9 1/4% per annum and is payable in cash semi-annually in arrears on
July 15 and January 15, starting January 15, 1998.  The 9 1/4% senior notes are

maturity, plus accrued and unpaid interest, declining to 100.000% of their
principal amount at maturity, plus accrued and unpaid interest, on or after July
15, 2005. In the event of specified equity investments in McLeodUSA by specified
strategic investors on or before July 15, 2000, we may, at our option, use all
or a portion of the net proceeds from such sale to redeem up to 33 1/3% of the
original principal amount of the 9 1/4% senior notes at a redemption price equal
to 109.25% of their principal amount plus accrued and unpaid interest, if any,
to but excluding the redemption date, provided that at least 66 2/3% of the
original principal amount of the 9 1/4% senior notes would remain outstanding
immediately after giving effect to such redemption. In addition, in the event of
a "Change of Control" (as defined in the indenture governing the 9 1/4% senior

     Recent Events.  On February 10, 1999, we acquired Talking Directories for
an aggregate of 2,556,390 shares of our Class A common stock.  In a related and
concurrent transaction, on February 10, 1999, we also acquired Info America for
an aggregate of 1,203,007 shares of our Class A common stock.  We paid
approximately $27 million of the outstanding obligations of Talking Directories
and Info America at the time of these transactions.

     On March 5, 1999, we acquired Dakota Telecommunications for an aggregate of
1,375,000 shares of our Class A common stock and the assumption of $31 million
in debt.

     On January 7, 1999, we entered into the Ovation merger agreement with
Ovation and several stockholders of Ovation to acquire Ovation, subject to
several conditions, for an amount of cash and a number of shares of Class A
common stock to be determined immediately prior to consummation of the
transaction.  We estimate that we will be required to issue approximately 
5.1 million shares of our Class A common stock and to pay approximately 
$141 million cash to effect the Ovation merger. We will also assume
approximately $95 million in Ovation debt. Consummation of the Ovation merger is
subject to the satisfaction of several conditions, including receipt of
specified regulatory approvals and other customary conditions. We cannot assure
you that the Ovation merger will be consummated.

     On February 22, 1999, we completed a private offering of $500 million 
aggregate principal amount of our 8 1/8% senior notes in which we received net
proceeds of approximately $487.8 million. Interest on the 8 1/8% senior notes 
accrues at the rate of 8 1/8% per annum and is payable in cash semi-annually 
in arrears on February 15 and August 15, starting August 15, 1999. The 8 1/8% 
senior notes are redeemable at our option, in whole or in part, at any time on
or after February 15, 2004 at 104.063% of their principal amount at maturity, 
plus accrued and unpaid interest, declining to 100.000% of their principal 
amount at maturity,plus accrued and unpaid interest, on or after February 15, 
2007. In the event of specified equity investments in McLeodUSA by specified 
strategic investors on or before February 15, 2002, we may, at our option, use
all or a portion of the net proceeds from such sale to redeem up to 33 1/3% of
the original principal amount of the 8 1/8% senior notes at a redemption price
equal to 108.125% of their principal amount plus accrued and unpaid interest,
if any, to but excluding the redemption date, provided that at least 66 2/3% 
of the original principal amount of the 8 1/8% senior notes would remain 
outstanding immediately after giving effect to such redemption. In addition, 
in the event of a "Change of Control" (as defined in the indenture governing 
the 8 1/8% senior notes) of McLeodUSA, each holder of 8 1/8% senior notes will
have the right to require us to repurchase all or any part of such holder's 
8 1/8% senior notes at a purchase price equal to 101% of the principal amount
of the 8 1/8% senior notes tendered by such holder plus accrued and unpaid 
interest, if any, to any "Change of Control Payment Date" (as defined in the 
indenture governing the 8 1/8% senior notes). The 8 1/8% senior notes will 
mature on February 15, 2009.

     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 are senior unsecured
obligations of McLeodUSA ranking pari passu in right of payment with all other
existing and future senior unsecured obligations of McLeodUSA and senior to all
existing and future subordinated debt of McLeodUSA. The 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 are effectively subordinated to all existing and future secured
indebtedness of McLeodUSA and our subsidiaries to the extent of the value of the
assets

                                       44

securing such indebtedness. The 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 also are
effectively subordinated to all existing and future third-party indebtedness and
other liabilities of our subsidiaries.

     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. These
restrictions affect, and in many cases significantly limit or prohibit, among
other things, our and our subsidiaries' ability to:

     .    incur additional indebtedness

     .    pay dividends or make distributions in respect of our or our
          subsidiaries' capital stock

     .    redeem 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

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

We cannot assure you 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 interests.

     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.  Failure to generate or raise sufficient
funds may require us to delay or abandon some of our expansion plans or
expenditures, which could have a material adverse effect on our business,
results of operations or financial condition.

     As of December 31, 1998, 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.  Our estimated aggregate capital
requirements include the projected costs of:


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

     .    expanding operations in existing and new markets

     .    developing wireless services

     .    funding general corporate expenses

     .    completing recent and pending acquisitions

     .    constructing, acquiring, developing or improving telecommunications
          assets

     The estimated costs and incremental capital needs associated with the
acquisitions of Talking Directories, Info America, Dakota Telecommunications and
Ovation are included in our estimated aggregate capital requirements.


     We expect to use the following to address our capital needs:

     .    approximately $487.8 million in net proceeds from our offering of 8 
          1/8% senior notes

     .    approximately $591.7 million of cash and investments on hand at
          December 31, 1998

     .    additional issuances of debt or equity securities

     .    projected operating cash flow

                                       45
<PAGE>
 
     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.  Accordingly, we may need additional
capital to continue to expand our markets, operations, facilities, network and
services.

     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.

     We have received a non-binding commitment from The Chase Manhattan Bank to
lead a syndication to provide a senior secured revolving credit facility.  We
cannot assure you, however, that we will be successful in obtaining such credit
facility on acceptable terms or at all.

     Failure to generate or raise sufficient funds may require us to delay or
abandon some of our expansion plans or expenditures, which could have a material
adverse effect on our business, results of operations or financial condition.
See "Business--Risk Factors--Failure to Raise Necessary Capital Could Restrict
Our Ability to Develop Our Network and Services and Engage in Strategic
Acquisitions."

Market Risk

     At December 31, 1998, we recorded the marketable equity securities that we
hold at a fair value of $30.6 million.  These securities have exposure to price
risk.  A hypothetical ten percent adverse change in quoted market prices would
amount to a decrease in the recorded value of investments of approximately 
$3 million. We believe our exposure to market price fluctuations on all other
investments is nominal due to the short-term nature of our investment portfolio.

     We have no material future earnings or cash flow exposures from changes in
interest rates on our long-term debt obligations, as substantially all of our
long-term debt obligations are fixed rate obligations.

Year 2000 Date Conversion

     We are currently verifying system readiness for the processing of date-
sensitive information by our computerized information systems. The Year 2000
problem impacts computer programs and hardware timers using two digits (rather
than four) to define the applicable year. Some of our programs and timers that
have time-sensitive functions may recognize a date using "00" as the year 1900
rather than 2000, which could result in miscalculations or system failures.

     We are reviewing our IT and non-IT computer systems and programs 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.  The review includes:

     1.   increasing employee awareness and communication of Year 2000 issues

                                       46
<PAGE>
 
     2.   inventorying hardware, software and data interfaces and confirming
          Year 2000 readiness of key vendors

     3.   identifying mission-critical components for internal systems, vendor
          relations and other third parties

     4.   estimating costs for remediation

     5.   estimating completion dates

     6.   testing and verifying systems

     7.   remediating any identified problems by correcting or replacing systems
          or components

     8.   implementing the remediation plan

     9.   developing contingency plans

     10.  training for contingency plans

     We have completed more than 95% of the activities required for the first
three of these steps, more than 75% of the activities required for the fourth
and fifth steps, more than 30% of the activities required for the sixth and
seventh steps and more than 20% of the activities required for the eighth step.
We are in the initial stages of performing the activities required to complete
the remaining steps and have begun to develop contingency plans to handle our
most reasonably likely worst case Year 2000 scenarios.  The completion
percentages do not include information for pending or recently completed
acquisitions.  The review and related Year 2000 activities have not caused us to
defer or forego, to any material degree, any other critical IT project.

     We estimate that our Year 2000 readiness costs will not exceed 
$11.5 million. We generally expense these costs as incurred. As of February 28,
1999, we had incurred costs of $2.3 million in connection with our Year 2000
readiness activities.

     Our estimate of our Year 2000 readiness costs is a forward-looking
statement within the meaning of the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Costs, results, performance and
effects of Year 2000 activities described in those forward-looking statements
may differ materially from actual costs, results, performance and effects in the
future due to the interrelationship and interdependence of our computer systems
and those of our vendors, material service providers, customers and other third
parties.

     We have not yet fully identified our most reasonably likely worst case Year
2000 scenarios. We continue to contact our vendors, suppliers and third parties
with which we have material relationships, regarding their state of readiness.
This activity is focused primarily on mission critical systems and key business
suppliers.  U S WEST, Ameritech and Southwestern Bell are our primary suppliers
of local central office switching and local lines.  Until we have received and
analyzed substantial responses from them we will have difficulty determining our
worst case scenarios.

     We have begun to develop contingency plans to handle worst case scenarios,
to the extent they can be identified fully. We intend to complete our
contingency planning after completing our determination of worst case scenarios.
Completion of these activities depends upon the responses to the inquiries we
have made of our major vendors, material service providers and third parties
with which we have material relationships. We have also begun work on
contingency plans for some systems identified as critical to our operations.

     If we, our major vendors, our material service providers or our customers
fail to address Year 2000 issues in a timely manner, such failure could have a
material adverse effect on our business, results of operations and financial
condition. We depend on local exchange carriers, 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, such interference could have a material adverse effect on our
future operations.  If other telecommunications carriers are unable to resolve
Year 2000 issues, it is likely that we will be affected to a similar degree as
others in the telecommunications industry.

Effects of New Accounting Standards

     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use.  This statement provides guidance on
accounting for the costs of computer software developed or obtained for internal
use and is required to be adopted no later than our 1999 fiscal year.  We plan
to modify our method of capitalization of such costs by adopting this statement
prospectively on January 1, 1999.  We are currently evaluating this statement
but do not expect it to have a material impact on our financial condition or
results of operations.

     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" 
("SFAS 133"). SFAS 133 establishes accounting and reporting standards requiring
that every derivative instrument (including derivative instruments embedded in
other contracts) be recorded in the balance sheet as either an asset or
liability measured at its fair value. SFAS 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative's gains and losses to offset related results on the hedged
item in the income statement, and requires that a company must formally
document, designate and assess the effectiveness of transactions that receive
hedge accounting.

     SFAS 133 is effective for fiscal years beginning after June 15, 1999.  A
company may also implement SFAS 133 as of the beginning of any fiscal quarter
after issuance (that is, fiscal quarters beginning June 16, 1998 and
thereafter).  SFAS 133 cannot be applied retroactively.  SFAS 133 must be
applied to (a) derivative instruments and (b) derivative instruments embedded in
hybrid contracts that were issued, acquired or substantively modified after
December 31, 1997 (and, at the company's election, before January 1, 1998).

     We do not expect the impact of the adoption of SFAS 133 to be material to
our results of operations as we do not currently hold any derivative instruments
or engage in hedging activities.

Inflation

     We do not believe that inflation has had a significant impact on our
consolidated operations.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk.

     At December 31, 1998, we recorded the marketable equity securities that we
hold at a fair value of $30.6 million.  These securities have exposure to price
risk.  A hypothetical ten percent adverse change in quoted market prices would
amount to a decrease in the recorded value of investments of approximately 
$3 million. We believe our exposure to market price fluctuations on all other
investments is nominal due to the short-term nature of our investment portfolio.

     We have no material future earnings or cash flow exposures from changes in
interest rates on our long-term debt obligations, as substantially all of our
long-term debt obligations are fixed rate obligations.

Item 8.  Financial Statements and Supplementary Data.

     Our consolidated financial statements, including our consolidated balance
sheets as of December 31, 1998 and 1997, consolidated statements of operations
for the years ended December 31, 1998, 1997 and 1996, consolidated statements of
stockholders' equity for the years ended December 31, 1998, 1997 and 1996,
consolidated statements of cash flows for the years ended December 31, 1998,
1997 and 1996, and notes to our consolidated financial statements, together with
a report thereon of Arthur Andersen LLP, dated January 27, 1999, are attached
hereto as pages F-2 through F-31.

Item 9.  Changes in and Disagreements with Accountants on Accounting and
         Financial Disclosure.

     On March 27, 1997, we engaged the accounting firm of Arthur Andersen LLP as
our principal independent accountants, to replace McGladrey & Pullen, LLP, our
former independent accountants, 

                                       48
<PAGE>
 
effective with such engagement. The decision to change independent accountants
was made following a review of competitive proposals submitted by Arthur
Andersen LLP and two other major public accounting firms, and was recommended by
the audit committee of our board of directors and approved by our board of
directors. McGladrey & Pullen, LLP did not resign and did not decline to stand
for re-election.

     During the fiscal years ended December 31, 1996 and 1995, and the interim
period between December 31, 1996 and March 27, 1997, there were no disagreements
with McGladrey & Pullen, LLP on any matter of accounting principles or
practices, financial statement disclosure, or auditing scope or procedure which
would have caused McGladrey & Pullen, LLP to make reference in their report to
such disagreements if not resolved to their satisfaction.

     McGladrey & Pullen, LLP's reports on the financial statements of McLeodUSA
for the fiscal years ended December 31, 1996 and 1995 contained no adverse
opinion or disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles.

     We provided McGladrey & Pullen, LLP with a copy of this disclosure and
requested that McGladrey & Pullen, LLP furnish us with a letter addressed to the
Securities and Exchange Commission stating whether it agrees with the above
statements. (A copy of the McGladrey & Pullen, LLP letter addressed to the SEC
is filed as Exhibit 16.1 to this Form 10-K).

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires our directors, officers and beneficial owners of more
than 10% of our Class A common stock to file with the SEC initial reports of
ownership of our equity securities and to file subsequent reports when there are
changes in such ownership. Officers, directors and beneficial owners of more
than 10% of our Class A common stock are required by SEC regulations to furnish
us with copies of all Section 16(a) reports they file.

  Based on our review of these reports and on written representations from the
reporting persons that no other reports were required, we believe that during
the fiscal year ended December 31, 1998 all Section 16(a) filing requirements
applicable to our officers, directors and greater than 10% beneficial owners
were complied with, except that one Form 4 for each of Stephen C. Gray and
Paul D. Rhines was filed late.

Compensation Committee Interlocks and Insider Participation

     During the fiscal year ended December 31, 1998, no member of our board of
directors served as a director or a member of the compensation committee of any
other company of which any executive officer served as a member of our board of
directors.

     In 1998, we paid 2060 Partnership, L.P. $1,654,000 for the rental of office
and parking spaces in Cedar Rapids, Iowa.  2001 Development Company, an Iowa
corporation, is the general partner and 80% owner of 2060 Partnership, L.P.
Alliant Energy and McLeodUSA own 54.55% and 3.03%, respectively, of the
outstanding stock of 2001 Development 

                                       56
<PAGE>
 
Company. The directors and officers of 2001 Development Company include Lee Liu
and Thomas M. Collins, directors of McLeodUSA, and Clark E. McLeod, a director
and executive officer of McLeodUSA.

     During 1998, we paid $86,000 to Shuttleworth & Ingersoll, P.C., a law firm
in Cedar Rapids, Iowa, for legal services rendered. We plan to retain the firm
in 1999.  We provide local and long distance telephone service for Shuttleworth
& Ingersoll.  Shuttleworth & Ingersoll paid us $64,000 for these services in
1998.  Thomas M. Collins is Of Counsel and a stockholder of Shuttleworth &
Ingersoll.

     For a description of other related-party transactions, see "Certain
Relationships and Related Transactions."

Employment, Confidentiality and Non-Competition Agreements

     We have entered into employment, confidentiality and non-competition
agreements with most members of our senior management, including the Named
Executive Officers.  These agreements typically provide that the applicable
senior management employee:

     .    may not compete with us during the term of his or her employment and
          for a one or two-year period following a termination for cause,
          resignation or voluntary termination of employment

     .    may not disclose any confidential information while employed by us and
          thereafter

The agreements have an indefinite term but may be terminated on 30 days' written
notice by either party, provided, however, that the confidentiality and non-
competition obligations survive any such termination. As partial consideration
for the execution of the employment, confidentiality and non-competition
agreements, we have granted to the employees signing such agreements options to
purchase shares of our Class A common stock at exercise prices which are based
on the fair market value of the Class A common stock on the date of grant. Such
options were granted under our 1996 Employee Stock Option Plan.

Change-of-Control Agreements

     We have entered into change-of-control agreements with our executive
officers, including the Named Executive Officers, which provide for payments and
benefits in connection with specified terminations of employment after a "change
of control" of McLeodUSA (as such term is defined in the change-of-control
agreements). The change-of-control agreements terminate on December 31, 2006,
unless a change of control has occurred during the six months preceding December
31, 2006, in which case the agreements terminate on December 31, 2007. If an
executive who is a party to a change-of-control agreement terminates employment
within six months after such a change of control or, if within 24 months after
such a change of control, the executive's employment is terminated by McLeodUSA
(other than for "disability," "cause," death or "retirement") or by the
executive following a "material reduction" in responsibilities or compensation
(as such terms are defined in the change-of-control agreements):

     .    the executive will be entitled to a lump sum payment equal to 12 or 
          24 times the executive's "average monthly compensation" (as defined in
          the change-of-control agreements) during the 12 months immediately
          preceding the change of control or the date of termination, whichever
          average monthly compensation is higher

     .    all of the executive's outstanding options to purchase stock of
          McLeodUSA will become immediately exercisable in full

     .    if the executive elects to continue coverage under McLeodUSA's group
          health plan, McLeodUSA will continue to pay the employer portion of
          the premiums for such coverage for the longer of 24 months or the
          period of coverage provided by the Internal Revenue Code of 1986, as
          amended (the "Code")

An executive who is entitled to payment(s) under a change-of-control agreement
is subject to a non-compete provision generally restricting the executive from
competing with McLeodUSA for a two-year period after the termination of
employment.

Directors' Compensation

     Directors who are also employees of McLeodUSA receive no directors fees.
Non-employee directors receive directors fees of $1,000 for each board of
directors and committee meeting attended in person and $500 for each board of
directors and committee meeting attended by telephone. In addition, directors
are reimbursed for their reasonable out-of-pocket travel expenses. Directors are
also eligible to receive grants of stock options under our Directors Stock
Option Plan (the "Directors Plan").

     The Directors Plan was adopted by our board of directors and approved by
our stockholders in 1993. On March 28, 1996, the Directors Plan was amended and
restated to be a "formula" plan providing for an automatic grant of stock
options to eligible non-employee directors. Under the Directors Plan, as
amended, the number of shares reserved for purchase upon exercise of options was
increased to an aggregate of 550,000 shares of our Class A common stock (subject
to adjustment for certain events, such as recapitalizations or stock splits,
effected without consideration) for grants to directors who are not officers or
employees of McLeodUSA (each an "Eligible Director"). Options to purchase
450,000 shares of Class A common stock had been granted under the Directors Plan
and options to purchase 142,314 shares of Class A common stock had been
exercised as of December 31, 1998. Under the Directors Plan, each Eligible
Director who commences service as a director is granted an initial option to
purchase 10,000 shares of Class A common stock. Each such Eligible Director is
also granted an additional option to purchase 5,000 shares of Class A common
stock immediately after each of the subsequent two annual stockholders' meetings
if the Eligible Director continues to be an Eligible Director. The Directors
Plan will terminate automatically on March 28, 2006, unless terminated earlier
by our board of directors.

     Other than the compensation described above, none of the directors received
any other compensation from McLeodUSA in 1998 in connection with their service
as directors.

Item 12.  Security Ownership of Certain Beneficial Owners and Management.

Stock Owned by Management

     The following beneficial ownership table sets forth information regarding
beneficial ownership of our Class A common stock as of February 28, 1999 by:

     .    each of our directors

     .    each Named Executive Officer

     .    all executive officers and directors as a group

Under the Exchange Act, a person is deemed to be a "beneficial owner" of a
security if he or she has or shares the power to vote or direct the voting of
such security or the power to dispose or direct the disposition of such
security. A person is also deemed to be a beneficial owner of any securities of
which that person has the right to acquire beneficial ownership within 60 days.
More than one person may be 

                                       58
<PAGE>
 
deemed to be a beneficial owner of the same securities. The percentage ownership
of each stockholder is calculated based on the total number of outstanding
shares of our Class A common stock as of February 28, 1999 plus those shares of
Class A common stock that such stockholder has the right to acquire within 60
days. Consequently, the denominator for calculating such percentage may be
different for each stockholder.


     The table is based upon information supplied by our directors and executive
officers.  Unless otherwise indicated in the footnotes to the table, each of the
stockholders listed has sole voting and dispositive power with respect to the
shares shown as beneficially owned. Also, except as noted below, the table
includes the following shares that the individuals named below have the right to
acquire within 60 days from February 28, 1999 upon exercise of options:

Investor Agreement and Stockholders' Agreements

     We have entered into an agreement (as amended, the "Investor Agreement")
with Alliant Energy, MidAmerican, Clark E. and Mary E. McLeod and several other
stockholders. The Investor Agreement provides that each of Alliant Energy,
MidAmerican and Clark and Mary McLeod, for so long as each owns at least 10% of
our outstanding capital stock, will vote such party's shares and take all action
within its power to:

                                       60
<PAGE>
 
     .    establish the size of our board of directors at nine directors

     .    cause to be elected to our board of directors one director designated
          by Alliant Energy for so long as Alliant Energy owns at least 10% of
          our outstanding capital stock

     .    cause to be elected to our board of directors one director designated
          by MidAmerican for so long as MidAmerican owns at least 10% of our
          outstanding capital stock

     .    cause to be elected to our board of directors three directors who are
          executive officers of McLeodUSA designated by Clark E. McLeod for so
          long as Clark E. and Mary E. McLeod collectively own at least 10% of
          our outstanding capital stock

     .    cause to be elected to our board of directors four independent
          directors nominated by the board

     On June 14, 1997, we entered into a stockholders' agreement (as amended,
the "June 1997 Stockholders' Agreement") with Alliant Energy, MidAmerican, Clark
and Mary McLeod and several shareholders of CCI.  The June 1997 Stockholders'
Agreement became effective on September 24, 1997.  Under the June 1997
Stockholders' Agreement, which amends and restates the Investor Agreement among
the parties thereto, each party agreed, for so long as such party owns at least
10% of our outstanding Class A common stock, for a period of three years after
September 24, 1997, 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 Alliant Energy for so long as Alliant Energy owns at least 10% of
          our outstanding Class A common stock

     .    cause to be elected to our board of directors one director designated
          by MidAmerican for so long as MidAmerican owns at least 10% of our
          outstanding Class A common stock

     .    cause to be elected to our board of directors three directors who are
          executive officers of McLeodUSA designated by Clark E. McLeod for so
          long as Clark E. and Mary E. McLeod collectively own at least 10% of
          our Class A common stock

     .    cause Richard A. Lumpkin to be elected to our board of directors for
          so long as the former shareholders of CCI who are a party to the
          agreement collectively own at least 10% of our Class A common stock

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


     The June 1997 Stockholders' Agreement also provides, among other things,
that:

     .    for a period ending in June 1999, and subject to exceptions, each of
          Alliant Energy and MidAmerican will refrain from acquiring, or
          agreeing or seeking to acquire, beneficial ownership of any securities
          issued by us

     .    if we grant any party to the agreement the opportunity to register any
          of our equity securities under the Securities Act, we will grant all
          other parties to the agreement the same opportunity to register their
          pro rata portion of our equity securities owned by them


The other operative provisions of the Investor Agreement remain unchanged in the
June 1997 Stockholders' Agreement.


     On November 18, 1998, we entered into a stockholders' agreement (the
"November 1998 Stockholders' Agreement") with Alliant Energy, Clark E. and Mary
E. McLeod, and Richard A. Lumpkin, Gail G. Lumpkin and several other parties
affiliated or related to the Lumpkins, but not including MidAmerican, which was
a party to prior agreements.

                                       61
<PAGE>
 
     The November 1998 Stockholders' Agreement provides, among other things,
that:

     .    until December 31, 2001, the parties to the agreement will not sell or
          otherwise dispose of any of our equity securities, or any other
          securities convertible into or exercisable for such equity securities,
          beneficially owned by them without receiving the prior written consent
          of our board of directors, except for transfers specifically permitted
          by the November 1998 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 to the agreement may sell or otherwise dispose of 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 or other disposition
          of our securities by such party, it will grant similar registration
          rights to the other parties to the agreement

     .    our board of directors will determine on an annual basis starting 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 or other disposition by the parties
          to the agreement

     .    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 other form which would not permit the inclusion of shares of
          Class A common stock owned by the parties to the agreement, we will
          give written notice of such offering to the parties and will undertake
          to register their shares of Class A common stock 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 November 1998 Stockholders' Agreement terminates on December 31, 2001.
In addition, if during any Annual Period we have not provided a party to the
agreement a reasonable opportunity to sell or otherwise dispose of 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 November 1998 Stockholders'
Agreement as it applies to such party within 10 business days following the end
of any such Annual Period.

     The November 1998 Stockholders' Agreement also contains provisions relating
to the designation and election of directors to our board of directors which
provisions take effect on the terms and under the circumstances specified in the
agreement.

     We have entered into a stockholders' agreement (the "Ovation Stockholders'
Agreement") with M/C Investors L.L.C. and Media/Communications Partners III
Limited Partnership (collectively, "M/C"), Alliant Energy, Clark E. and Mary E.
McLeod, Richard A. and Gail G. Lumpkin and several other parties related to the
Lumpkins with respect to the shares of our Class A common stock that M/C will
receive in the Ovation merger.

     The Ovation Stockholders' Agreement provides that:

     .    until December 31, 2001, M/C will not sell or otherwise dispose of any
          of our equity securities or any other securities convertible into or
          exercisable for such equity securities beneficially owned by M/C as a
          result of the Ovation merger without receiving the prior written
          consent of our board of directors, except for transfers specifically
          permitted by the Ovation Stockholders' Agreement

                                       62
<PAGE>
 
     .    our board of directors will determine on a quarterly basis starting
          with the quarter ending December 31, 1999 and ending on December 31,
          2001, the aggregate number, if any, of shares of Class A common stock,
          not to exceed in the aggregate 50,000 shares per quarter, that M/C may
          sell or otherwise dispose of during designated trading periods
          following the release of our quarterly or annual financial results

     .    our board of directors will determine on an annual basis for each of
          the years ending December 31, 2000 and December 31, 2001, 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 M/C as of the completion of the Ovation merger,
          to be registered by us under the Securities Act for sale or other
          disposition by M/C

     .    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 other form which would not permit the inclusion of shares of
          Class A common stock owned by M/C, during the period starting on
          January 1, 2000 and ending on December 31, 2001, we will give written
          notice of such offering to M/C and will undertake to register a number
          of shares of Class A common stock owned by M/C, if any, determined by
          our board of directors

     .    we may subsequently determine not to register any shares owned by M/C
          under the Securities Act and may either not file a registration
          statement or otherwise withdraw or abandon a registration statement
          previously filed

     The Ovation Stockholders' Agreement also contains various provisions
intended to insure that M/C is generally treated on a similar basis to the other
parties to the agreement in connection with any sale or other disposition of our
securities permitted by us with respect to any of these other parties or any
registration rights granted by us to any of these other parties under the
November 1998 Stockholders' Agreement for the period starting on January 1, 2000
and ending on December 31, 2001.  Similar protective rights are also granted in
the Ovation Stockholders' Agreement to each of these other parties with respect
to any sale or other disposition or registration of our securities owned by M/C
permitted by us under the Ovation Stockholders' Agreement.  In addition, during
the year ending December 31, 1999, if we participate in a strategic transaction
with an outside investor who agrees to acquire our securities at a premium to
their then average trading price, after we have been paid or otherwise received
our consideration or proceeds from such transaction as determined by us, the
parties to the Ovation Stockholders' Agreement may be entitled to participate in
such transaction on a pro rata basis as determined by our board of directors.

     Under the Ovation Stockholders' Agreement, each party has agreed, for so
long as each such party owns at least 2.5 million shares of our Class A common
stock, in the case of M/C, or 4.0 million shares of our Class A common stock, in
the case of the other parties, to (1) establish the size of our board of
directors at up to 11 directors, (2) cause to be elected to our board of
directors one director designated by M/C, for so long as M/C owns at least 2.5
million shares of our Class A common stock, and (3) cause to be elected to our
board the directors designated by the other parties as set forth in the Ovation
Stockholders' Agreement.

          The Ovation Stockholders' Agreement terminates on the earlier to occur
of the termination of the Ovation merger agreement and 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 or other disposition 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 the effective
time of the Ovation merger or (2) after January 1, 2000, the November 1998
Stockholders' Agreement has been terminated by all parties to such agreement,
then M/C may terminate the Ovation Stockholders' Agreement by providing written
notice of termination to all other parties (x) in the case of clause (1) above,
no later than 30 days following the end of such year and (y) in the case of
clause (2) above, at any time after January 1, 2000.  Lastly, the Ovation
Stockholders' Agreement will be terminated with respect to all parties other
than McLeodUSA and M/C at such time as the November 1998 Stockholders' Agreement
is terminated.

     In April 1997, McLeodUSA, Clark E. McLeod, Stephen C. Gray and Blake O.
Fisher, Jr. jointly purchased a jet aircraft for an aggregate of approximately
$2.25 million. Subsequently, the ownership was reallocated and Arthur L.
Christoffersen and Richard A. Lumpkin each purchased an interest. In connection
with the ownership reallocation, we paid approximately $1.35 million for a 60%
ownership percentage and Messrs. McLeod, Gray, Fisher, Christoffersen and
Lumpkin each paid approximately $180,000 for an ownership percentage of 8% each.
During 1998, Messrs. Fisher and Christoffersen sold their ownership back to
McLeodUSA for $180,000 each and Mr. McLeod purchased an additional 4% ownership
from us for $90,000, increasing his ownership percentage from 8% to 12%.
McLeodUSA and Messrs. McLeod, Gray and Lumpkin are parties to a Joint Ownership
Agreement by which they have agreed to share the operational expenses of the
aircraft in proportion to their respective ownership interest in the aircraft
(72% by McLeodUSA, 12% by Mr. McLeod and 8% each by Messrs. Gray and Lumpkin).
Messrs. McLeod and Fisher are directors and executive officers of McLeodUSA and
Mr. Christoffersen is an executive officer of McLeodUSA.

     We have entered into two agreements with Alliant Energy by which Alliant
Energy has agreed to grant us access to towers, rights-of-way, conduits and
poles in exchange for capacity on our communications network.

     In February 1996, we entered into two agreements with MidAmerican by which
MidAmerican has agreed to grant us access to towers, rights-of-way, conduits and

     On July 18, 1995 and March 29, 1996, respectively, we loaned $75,000 to
each of Kirk E. Kaalberg and Stephen K. Brandenburg in exchange for unsecured
notes executed by Mr. Kaalberg and Mr. Brandenburg, respectively. Interest
accrues on both loan amounts at the applicable rate established in Internal
Revenue Service regulations. Mr. Brandenburg made an annual interest-only
payment in 1998 and will make annual payments of $25,000 plus accrued interest
in each of the next three years. Mr. Kaalberg made an annual payment of $25,000
plus accrued interest in 1998 and will make similar payments in each of the next
two years.  Messrs. Kaalberg and Brandenburg are executive officers of
McLeodUSA.

     In December 1998, we entered into a split dollar arrangement for life
insurance policies owned by the McLeod Family 1998 Special Trust on the joint
lives of Clark and Mary McLeod.  The McLeod Family 1998 Special Trust agreed to
assign the policies to us as collateral for our payment of the premiums for
these policies.  No loans have been taken against these policies.  In 1998, the
premium payments paid by us on these policies totaled $1,880,000.  The aggregate
face amount of the policies is $113,000,000.  The McLeod Family 1998 Special
Trust is sole owner and beneficiary of each policy. We have agreed with Clark
and Mary McLeod that one of the principle reasons for entering into this
arrangement is to avoid any need for their heirs to liquidate their holdings of
our Class A common stock at or soon after the death of one or both of them.
Clark and Mary McLeod have agreed to restrictions on their ability to sell or

                                       64

otherwise dispose of their shares of Class A common stock.  See "-- Investor
Agreement and Stockholders' Agreements."  We also paid premiums of $138,257 for
a universal life policy on Clark and Mary McLeod with a face value of
$13,500,000.  We are the beneficiary of this policy.

     In March 1996, our board of directors adopted a policy requiring that any
material transactions between McLeodUSA and persons or entities affiliated with
officers, directors or principal stockholders of McLeodUSA be on terms no less
favorable to McLeodUSA than reasonably could have been obtained in arms' length
transactions with independent third parties or be approved by a majority of
disinterested directors.

                                    GLOSSARY

     Access--Telecommunications services that permit long distance carriers to
use local exchange facilities to originate and/or terminate long distance
service.

     Access to Rights-of-Way--Access to poles, ducts, conduits and other rights-
of-way.

     CAP (competitive access provider)--A company that provides its customers
with an alternative to the local exchange company for local transport of private
line and special access telecommunications services.

     Central offices--The switching centers or central switching facilities of
the local exchange companies.

     Collocation--The ability of a CAP such as McLeodUSA to connect its network
to the LECs central offices. Physical collocation occurs when a CAP places its
network connection equipment inside the local exchange company's central
offices. Virtual collocation is an alternative to physical collocation by which
the local exchange company permits a CAP to connect its network to the local
exchange company's central offices on comparable terms, even though the CAP's
network connection equipment is not physically located inside the central
offices.

     Dedicated--Telecommunications service or capacity reserved for use by
particular customers.

     Dialing Parity--The ability of a competing local or toll service provider
to provide telecommunications services in such a manner that customers have the
ability to route automatically, without the use of any access code, their
telecommunications to the service provider of the customer's designation.

     Digital--A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary digits 0 and 1. Digital transmission and switching technologies employ a
sequence of these pulses to represent information as opposed to the continuously
variable analog signal. The precise digital numbers minimize distortion (such as
graininess or snow in the case of video transmission, or static or other
background distortion in the case of audio transmission).

     FCC--Federal Communications Commission.

     Interconnection--Interconnection of facilities between or among local
exchange carriers, including potential physical collocation of one carrier's
equipment in the other carrier's premises to facilitate such interconnection.

     Initial Interconnection Decisions--Rulings by the FCC announced in
September 1992 and August 1993, which require the regional Bell operating
companies and most other large local exchange carriers to provide
interconnection in local exchange company central offices to any CAP, long
distance carrier or end user seeking such interconnection for the provision of
interstate special access and switched access transport services.

     Interconnection Decision--The August 1996 order issued by the FCC
implementing the interconnection provisions of the Telecommunications Act of
1996.

     InterLATA--Telecommunications services originating in a LATA and
terminating outside of that LATA.

     IntraLATA--Telecommunications services originating and terminating in the
same LATA.

     LATA (local access and transport area)--A geographic area composed of
contiguous local exchanges, usually but not always within a single state. The
State of Iowa contains all or part of five LATAs; the State of Illinois contains
all or part of 17 LATAs. There are approximately 200 LATAs in the United States.

                                       75
<PAGE>
 
     Local exchange--A geographic area determined by the appropriate state
regulatory authority in which calls generally are transmitted without toll
charges to the calling or called party.

     LEC (local exchange carrier)--A company providing local telephone services.

     Long distance carriers (interexchange carriers)--Long distance carriers
provide services between local exchanges on an interstate or intrastate basis. A
long distance carrier may offer services over its own or another carrier's
facilities.

     Number portability--The ability of an end user to change local exchange
carriers while retaining the same telephone number.

     POPs (points of presence)--Locations where a long distance carrier has
installed transmission equipment in a service area that serves as, or relays
calls to, a network switching center of that long distance carrier.

     Private line--A dedicated telecommunications connection between end user
locations.

     Public switched network--That portion of a local exchange company's network
available to all users generally on a shared basis (i.e., not dedicated to a
particular user). Traffic along the public switched network is generally
switched at the local exchange company's central offices.

     Public utility commission--A state regulatory body, established in most
states, which regulates utilities, including telephone companies providing
intrastate services.

     Reciprocal compensation--The same compensation of a new competitive local
exchange carrier for termination of a local call by the local exchange carrier
on its network, as the new competitor pays the local exchange carrier for
termination of local calls on the local exchange carrier network.

     Resale--Resale by a provider of telecommunications services (such as a
local exchange carrier) of such services to other providers or carriers on a
wholesale or a retail basis.

     Route mile--The number of miles of the telecommunications path in which
fiber optic cables are installed.

     Self-healing ring--A self-healing ring is a network design in which the
network backbone consists of a continuous ring connecting a central hub facility
with one or more network nodes (such as customer premises). Traffic is routed
between the hub and each of the nodes simultaneously in both a clockwise and a
counterclockwise direction. In the event of a cable cut or component failure
along one of these paths, traffic will continue to flow along the alternate path
so no traffic is lost. In the event of a catastrophic node failure, other nodes
will be unaffected because traffic will continue to flow along whichever path
(primary or alternate) does not pass through the affected node. The switch from
the primary to the alternate path will be imperceptible to most users.

     Special access services--The lease of private, dedicated telecommunications
lines or "circuits" along the network of a local exchange company or a CAP,

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors and Stockholders of
McLeodUSA Incorporated:

  We have audited the accompanying consolidated balance sheets of McLeodUSA
Incorporated (a Delaware corporation) and subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of operations and
comprehensive income, stockholders' equity, and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of McLeodUSA Incorporated's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of McLeodUSA
Incorporated and subsidiaries as of December 31, 1998 and 1997, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1998 in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

     Nature of business: McLeodUSA Incorporated and subsidiaries (the "Company")
is a diversified telecommunications company, incorporated in Delaware, that
provides a broad range of products and services to business customers in Iowa,
Illinois, North Dakota, South Dakota, Minnesota, Indiana, Colorado and Wyoming
and residential customers in Iowa, Illinois, North Dakota, South Dakota,
Wisconsin and Colorado. The Company's services primarily include local and long-
distance telecommunications services, telecommunications network maintenance
services and telephone equipment sales, service and installation, private line
and data services, the sale of advertising space in telephone directories, the
operation of an independent local exchange company, and telemarketing services.
The Company's business is highly competitive and is subject to various federal,
state and local regulations. In 1997, the Company's stockholders approved a
change in its name to McLeodUSA Incorporated from McLeod, Inc.

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

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

     Principles of consolidation: The accompanying financial statements include
those of the Company and its subsidiaries, substantially all of which are wholly
owned. All significant intercompany items and transactions have been eliminated
in consolidation.

     Regulatory accounting: Illinois Consolidated Telephone Company ("ICTC"), an
independent local exchange carrier and a wholly owned subsidiary of the Company,
prepares its financial statements in accordance with the provisions of Statement
of Financial Accounting Standards No. 71, "Accounting for the Effects of Certain
Types of Regulation" ("SFAS No. 71"). The provisions of SFAS No. 71 require,
among other things, that regulated enterprises reflect rate actions of
regulators in their financial statements, when appropriate. These rate actions
can provide reasonable assurance of the existence of an asset, reduce or
eliminate the value of an asset, or impose a liability on a regulated
enterprise. SFAS No. 71 also specifies that the actions of a regulator can
eliminate only liabilities imposed by the regulator.

     Cash and cash equivalents: For purposes of reporting cash flows, the
Company considers all highly liquid debt instruments purchased with a maturity
of three months or less and all certificates of deposit, regardless of maturity,
to be cash equivalents.

     Investments: Management determines the appropriate classification of the
securities at the time they are acquired and evaluates the appropriateness of
such classifications at each balance sheet date. The Company has classified its
securities as available-for-sale. Available-for-sale securities are stated at
fair value, and unrealized holding gains and losses are reported as a component
of stockholders' equity. Realized gains and losses are determined on the basis
of the specific securities sold.

     Trade receivables: In accordance with the industry practice for the
publication of telephone directories, trade receivables include certain unbilled
revenue from installment contracts. It is anticipated that a substantial portion
of all such amounts at December 31, 1997 and 1998 will be collected within one
year (see Note 2).

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

  Inventory: Inventory is carried principally at the lower of average cost or
market and consists primarily of new and reusable parts to maintain fiber optic
networks and parts and equipment used in the maintenance and installation of
telephone systems. All inventory is classified as raw materials.

  Property and equipment: Property and equipment is stated at cost. Construction
costs, including interest, are capitalized during the installation of fiber
optic telecommunications networks. Interest expense was also capitalized as part
of the construction of the Company's headquarters buildings and the development
of the Company's software.

  ICTC's property and equipment for its regulated operations is summarized as
follows at December 31, 1998 (In thousands):

  When regulated property and equipment are retired, the original cost, net of
salvage, is charged against accumulated depreciation. The cost of maintenance
and repairs of property and equipment including the cost of replacing minor
items not constituting substantial betterments is charged to operating expense.

  The provision for depreciation of regulated property and equipment is based
upon remaining life rates for property placed in service through 1980 and equal
life rates for property additions placed in service after 1980. The regulated
provision is equivalent to an annual composite rate of 5.58% for 1998.

  The provision for depreciation of nonregulated property and equipment is
recorded using the straight-line method based on the following estimated useful
lives:

</TABLE>

  The Company's telecommunications networks are subject to technological risks
and rapid market changes due to new products and services and changing customer
demand. These changes may result in changes in the estimated economic lives of
these assets.

  Other investments: Other investments primarily includes $26,195,000 for a
minority interest in a limited partnership which provides cellular services to
customers in east central Illinois. The Company follows the equity method of
accounting for this investment, which recognizes the Company's proportionate
share of the income and losses accruing to it under the terms of its partnership
agreement.

  Goodwill: Goodwill resulting from the Company's acquisitions is being
amortized over a range of 15 to 30 years using the straight-line method and the
acquisitions are periodically reviewed for impairment

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

based upon an assessment of future operations to ensure that it is appropriately
valued. Accumulated amortization on goodwill totaled $16,356,000 and $5,834,000
at December 31, 1998 and 1997, respectively.

  Other intangibles: Other intangibles consist of customer lists and noncompete
agreements related to the Company's acquisitions, deferred line installation
costs incurred in the establishment of local access lines for customers and
franchise rights to provide cable services to customers in three Illinois
counties and in a Michigan city. The customer lists and noncompete agreements
are being amortized using the straight-line method over periods ranging from 3
to 15 years. The deferred line installation costs are being amortized using the
straight-line method over 36 to 60 months, which approximates the average lives
of residential and business customer contracts. The franchise rights are being
amortized using the straight-line method over periods ranging from 10 to 15
years. Accumulated amortization on the other intangibles totaled $25,066,000 and
$9,158,000 at December 31, 1998 and 1997, respectively.

  Income tax matters: The Company recognizes deferred tax assets and liabilities
for the expected future tax consequences of events that have been included in
the financial statements or tax returns. Under this method, deferred tax assets
and liabilities are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Net
deferred tax assets are reduced by a valuation allowance when appropriate (see
Note 6). Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment.

  Deferred revenue: Amounts received in advance under long-term leases of fiber
optic telecommunications networks are recognized as revenue on a straight-line
basis over the life of the leases.

  Revenue recognition: Revenues for local and long-distance services are
recognized when subscribers use telecommunications services. The revenue from
long-term leases of fiber optic telecommunications networks is recognized over
the term of the lease. Base annual revenue for telecommunications network
maintenance is recognized on a straight-line basis over the term of the
contract. Additional services provided under these contracts are recognized as
the services are performed.

  ICTC's toll revenue is provided through a combination of billed carrier access
charges, traditional end-user billed toll revenues, interstate tariffed
subscriber line charges and ICTC's share of revenues and expenses from the non-
traffic sensitive pool administered by the National Exchange Carrier
Association.

  As allowed by the FCC, ICTC's presubscribed rate of return on interstate
access revenues for 1998 was 11.25%. The FCC further restricted overall
interstate revenues to a maximum 11.50% rate of return on related investments,
or to a maximum of 11.65% rate of return on related investments per any
individual rate element.

  Fees from telemarketing contracts are recognized as revenue in the period the
services are performed.

  Revenues from directories are recorded upon publication.

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

  Customer deposits consist of cash received from customers at the time a sales
contract is signed. They are recorded as revenue when the related directory is
published or when the related service is performed.

  Cost of service and deferred expenses: Cost of service includes local and 
long-distance services purchased from certain Regional Bell Operating Companies
and interexchange carriers, the cost of providing local exchange services to
customers in ICTC's service area and the cost of operating the Company's fiber
optic telecommunications networks. Cost of service also includes production
costs associated with the publication of directories and direct costs associated
with telemarketing services and the sale and installation of telephone systems.

  Deferred expenses consist of production and selling costs on unpublished
directory advertising orders. They are expensed when the related directory is
published and the related revenue of the directory is recognized.

  Key business suppliers: U S WEST, Ameritech and Southwestern Bell Company are
the Company's primary suppliers of local central office switching and local
lines.

  Stock options issued to employees: In fiscal year 1996, the Company adopted
the provisions of SFAS No. 123, Accounting for Stock-Based Compensation, which
establishes a fair value based method for the financial reporting of its stock-
based employee compensation plans. The Company measures compensation using the
intrinsic value based method as prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees. Under this method,
compensation is measured as the difference between the market value of the stock
on the grant date, less the amount required to be paid for the stock. The
difference, if any, is charged to expense over the vesting period of the
options.

  The estimated market value used for the stock options granted was determined
on a periodic basis by the Company's Board of Directors prior to the Company's
initial public offering on June 10, 1996. Subsequent to the Company's initial
public offering, the market value used for stock options granted is based upon
the closing price of the Class A common stock on the day before the grant date.

  Stock options issued to nonemployees: The Company uses the Black-Scholes model
to determine the fair value of the stock options issued to nonemployees at the
date of grant. This amount is amortized to expense over the vesting period of
the options.

  Loss per common share: Loss per common share has been computed using the
weighted average number of shares of common stock outstanding after giving
effect to the recapitalization in 1996. All stock options granted are anti-
dilutive, and therefore excluded from the computation of earnings per share. In
the future, these stock options may become dilutive.

  Fair value of financial instruments: The carrying amount of cash and cash
equivalents approximates fair value due to the short maturity of the
instruments. For other investments for which there are no quoted market prices,
a reasonable estimate of fair value could not be made without incurring
excessive cost. The $29.9 million carrying amount of unquoted investments at
December 31, 1998, represents the original cost of the investments, which
management believes is not impaired. The fair value of the Company's long-term
debt is estimated to be $1.3 billion based on the quoted market rates for the
same or similar issues or the current rates offered to the Company for debt with
similar maturities.

NOTE 3. INVESTMENTS

  At December 31, 1998, the Company held $187,136,000, $30,298,000 and
$30,614,000 in corporate debt securities, United States Government and
governmental agency securities and marketable equity securities, respectively.
At December 31, 1997, the Company held $4,493,000, $94,341,000 and $27,491,000
in repurchase agreements, corporate debt securities and marketable equity
securities, respectively. The Company has classified these securities as
available-for-sale, and at December 31, 1998 and 1997, the debt securities'
amortized cost approximates fair value. The marketable equity securities have
been recorded at their fair market value at December 31, 1998. The available-
for-sale securities have been classified as cash and cash equivalents, and
investment in available-for-sale securities-current, with $111,463,000 and
$136,585,000, respectively, being recorded in each classification at December
31, 1998. At December 31, 1997, $91,629,000 and $34,696,000, respectively, were
recorded in each classification.

  The contractual maturities of the available-for-sale securities of
$248,048,000 and $126,325,000 in 1998 and 1997, respectively, are due within one
year.

  Expected maturities will differ from contractual maturities because the
issuers of certain debt securities have the right to call or prepay their
obligations without any penalties. The amount classified as current assets on
the accompanying balance sheets represent the expected maturities of the debt
securities during the next year.

NOTE 4. PLEDGED ASSETS AND DEBT

  Debt offerings: On March 4, 1997, the Company completed a private offering of
10 1/2% Senior Discount Notes (the "Senior Discount Notes") due March 1, 2007 at
an original issue discount in which the Company received approximately $288.9
million in net proceeds. The Company filed a registration statement with the
Securities and Exchange Commission ("SEC") for the registration of $500 million
principal amount at maturity of 10 1/2% Senior Discount Notes due March 1, 2007
(the "Senior Discount Exchange Notes") to be offered in exchange for the Senior
Discount Notes (the "Senior Discount Exchange Offer"). The registration
statement was declared effective by the SEC on July 28, 1997 and the Senior
Discount Exchange Offer was commenced. The Senior Discount Exchange Offer
expired on August 24, 1997, at which time all of the Senior Discount Notes were
exchanged for the Senior Discount Exchange Notes. The form and terms of the
Senior Discount Exchange Notes are identical in all material respects to the
form and terms of the Senior Discount Notes except that (i) the Senior Discount
Exchange Notes have been registered under the Securities Act of 1933 (the
"Securities Act") and (ii) holders of the Senior Discount Exchange Notes are not
entitled to certain rights under a registration agreement relating to the Senior
Discount Notes. The Senior Discount Exchange Notes rank pari passu in right of
payment with all existing and future senior unsecured indebtedness of the
Company and rank senior in right of payment to all existing and future
subordinated indebtedness of the Company. The Senior Discount Exchange Notes
accrete interest at a rate of 10 1/2% per year, compounded semi-annually, to an
aggregate principal amount of $500 million by March 1, 2002. Interest will not
accrue on the Senior Discount Exchange Notes for five years, after which time
the Senior Discount Exchange Notes will accrue interest at 10 1/2%, payable 
semi-annually. The indenture related to the Senior Discount Exchange Notes
contains certain covenants which, among other things, restrict the ability of
the Company to incur additional indebtedness, pay dividends or make
distributions of the Company's or its subsidiaries' stock, enter into sale and
leaseback transactions, create liens, enter into transactions with affiliates or
related persons, or consolidate, merge or sell all of its assets.

  On July 21, 1997, the Company completed a private offering of $225 million
aggregate principal amount of 9 1/4% Senior Notes due July 15, 2007 (the "Senior
Notes"). The Company received net proceeds of approximately $217.6 million from
the Senior Note offering. Interest on the Senior Notes is payable in cash semi-
annually in arrears on July 15 and January 15 of each year at a rate of 9 1/4%
per annum, commencing January 15, 1998. The Senior Notes rank pari passu in
right of payment with all existing and future senior unsecured indebtedness of
the Company and rank senior in right of payment to all existing and future
subordinated indebtedness of the Company. As of December 31, 1997, the Senior
Notes had not been registered under the Securities Act and therefore cannot be
offered for resale, resold or otherwise transferred unless so registered or
unless an applicable exemption from the registration requirements of the
Securities Act is available. The Company has filed a registration statement with
the SEC for the registration of $225 million aggregate principal amount of 9
1/4% Senior Notes due July 15, 2007 (the "Exchange Notes") to be offered in
exchange for the Senior Notes (the "Exchange Offer"). The registration statement
was declared effective by the SEC on December 1, 1997, and the Exchange Offer
was commenced on December 2, 1997. The Exchange Offer expired on January 9,
1998, at which time all of the Senior Notes were exchanged for the Exchange
Notes. The form and terms of the Exchange Notes are identical in all material
respects to the form and terms of the Senior Notes except that (i) the Exchange
Notes have been registered under the Securities Act and (ii) holders of the
Exchange Notes will not be entitled to certain rights under a registration
agreement relating to the Senior Notes. The indentures relating to the Senior
Notes and the Exchange Notes contain certain covenants which are materially the
same as the covenants relating to the Senior Discount Exchange Notes.

  On March 16, 1998, the Company completed a private offering of its 8 3/8%
Senior Notes due March 5, 2008 (the "March 1998 Privately Placed Senior Notes"),

in exchange for the March 1998 Privately Placed Senior Notes (the "March
Exchange Offer"). The registration statement was declared effective by the SEC
on May 15, 1998 and the March Exchange Offer was commenced. The March Exchange
Offer expired on June 25, 1998, at which time all of the March 1998 Privately

the March Exchange Notes have been registered under the Securities Act of 1933
(the "Securities Act") and (ii) holders of the March Exchange Notes are not
entitled to certain rights under a registration agreement related to the March
1998 Privately Placed Senior Notes. Interest on the March 1998 Senior Notes will
be payable in cash semi-annually in arrears on March 15 and September 15 of each
year at a rate of 8 3/8% per annum, commencing September 15, 1998. The March
1998 Senior Notes rank pari passu in right of payment with all existing and
future senior unsecured indebtedness of the Company and rank senior in right of
payment to all existing and future subordinated indebtedness. The March 1998
Senior Notes will mature on March 15, 2008. The March 1998 Senior Notes will be
redeemable at the option of the Company, in whole or in part, at any time on or
after March 15, 2003 at 104.188% of their principal amount at maturity, plus
accrued and unpaid interest, declining to 100.000% of their principal amount at
maturity, plus accrued and unpaid interest, on or after March 15, 2006. In the
event of certain equity investments in the Company by certain strategic
investors on or before March 15, 2001, the Company may, at its option, use all
or a portion of the net proceeds from such sale to redeem up to 33 1/3% of the
originally issued principal amount of the March 1998 Senior Notes at a
redemption price equal to 108.375% of the principal amount of the March 1998
Senior Notes plus accrued and unpaid interest thereon, if any, to the redemption
date, provided that at least 66 2/3% of the originally issued principal amount
of the March 1998 Senior Notes would remain outstanding immediately after giving

Notes tendered by such holder plus accrued and unpaid interest, if any, to any
Change of Control Payment Date (as defined in the March 1998 Senior Note
Indenture).

  The March 1998 Senior Note Indenture imposes operating and financial
restrictions on the Company and its subsidiaries.  These restrictions affect,
and in certain cases significantly limit or prohibit, among other things, the
ability of the Company and its subsidiaries to incur additional indebtedness,
pay dividends or make distributions in respect of the Company's or such
subsidiaries' capital stock, make other restricted payments, enter into sale and
leaseback transactions, create liens upon assets, enter into transactions with
affiliates ore related persons, sell assets, or consolidate, merge or sell all

   In 1996, the Company used a portion of the proceeds from the Company's
initial public offering (see Note 8) to pay off all existing indebtedness under
three line of credit facilities, which were then canceled. Options to purchase
Class B common stock were granted to a stockholder which had guaranteed
borrowings under two of the facilities. The Company used the Black-Scholes model
to determine the value of the options, which was approximately $3,400,000, at
the date of grant. This value was being amortized over the vesting period of the
options. Upon cancellation of the credit facilities, the options' vesting
schedule and amortization of the fair value of the options were terminated. A
total of 1,300,688 Class B common stock options were outstanding at December 31,
1998 and December 31, 1997.

NOTE 5.   LEASES AND COMMITMENTS--(CONTINUED)

  Network construction:  During 1995, the Company was awarded contracts from
the State of Iowa to build fiber optic telecommunications network segments
throughout the State of Iowa. As of December 31, 1998, the contracts call for
the construction of 235 network segments. Upon completion of each segment, the
Company will receive approximately $115,000 for a seven-year lease for certain
capacity on that segment. The Company will recognize this revenue of
approximately $27,025,000 on a straight-line basis over the term of the lease
based on the relationship of individual segment costs to total projected costs.
For the years ended December 31, 1998, 1997 and 1996, revenue of $2,763,000,
$1,794,000 and $445,000, respectively, had been recognized under these
contracts.

  The Company estimates that minimum future construction costs required to
fulfill its obligations under the 1995 contract with the State of Iowa would be
approximately $5,393,000.  The Company, however, expects that its actual
construction costs will be higher with respect to such network segments, because
the Company is adding more fiber and route miles than is contractually required
with respect to such construction, in order to optimize the design of its
network. The Company anticipates that the minimum costs to complete this project
will be incurred in 1999.

  Buildings:  In August 1996, the Company purchased approximately 194 acres of
land on which the Company constructed its headquarters and associated buildings.
Of the land purchased, approximately 75 acres was purchased from a subsidiary of
a stockholder for approximately $692,000. At December 31, 1998, the total
remaining contracted commitments on the building in progress is approximately $8
million.

  Alcatel: In January 1999 the Company entered into an agreement with Alcatel
USA Marketing, Inc. to purchase equipment, software and services for a total
commitment of $200,000,000 over a six (6) year period. If McLeodUSA does not
meet the committed purchases on a cumulative annual basis, Alcatel retains the
right to renegotiate the applicable prices. If regulatory conditions
substantially prevent the Company from continuing to implement these plans, the
Company has the option to request renegotiation of unit prices based on revised
quantities of products or to renegotiate unit prices based on the quantities of
products purchased to that time and cease any further purchases of products.

NOTE 7.   STOCK-BASED COMPENSATION PLANS

  At December 31, 1998, the Company has various stock-based compensation plans
which are described below. Grants under the Company's stock option plans are
accounted for in accordance with Accounting Principles Board (APB) Opinion No.
25 and related Interpretations. The Company granted a total of 1,653,688 stock
options in January and February 1996 at an exercise price of $2.67 per share.
The estimated aggregate fair market value of these options at the date of grant
was later determined to exceed the aggregate exercise price by approximately
$9,190,000. Additionally, in September 1997, the Company granted a total of
1,468,945 stock options at an exercise price of $24.50 per share. The aggregate
fair market value of these options at the date of grant exceeded the aggregate
exercise price by approximately $15,790,000. As a result, the Company is
amortizing these amounts over the four-year vesting period of the options.
Compensation cost of $5,820,000 and $2,993,000 has been charged to income for
the year ended December 31, 1998 and 1997, respectively, using the intrinsic
value based method as prescribed by APB No. 25. Had compensation cost for all of
the stock-based compensation plans been determined based on the grant date fair
values of awards granted during 1998, 1997 and 1996, as prescribed by SFAS No.
123, reported net loss and loss per common share would have been as follows (in
thousands, except per share data):

  1992, 1993 and 1995 Incentive Stock Option Plans:   The Company has reserved
2,903,243 shares of Class A common stock for issuance to employees under the
1992, 1993 and 1995 Incentive Stock Option Plans. Options outstanding under
these plans were granted at prices equal to the estimated fair market value on
the dates of grant as determined by the Company's Board of Directors. Under the
1992 and 1993 plans, all options granted become exercisable at a rate of 25% per
year, on a cumulative basis, and expire seven years after the date of grant.
Under the 1995 plan, all options, except for options granted to the Company's
chairman and chief executive officer, become exercisable at a rate of 25% per
year, on a cumulative basis, beginning five years from the date of grant. The
options granted to the Company's chairman and chief executive officer vest at a
rate of 20% per year on a cumulative basis. All options granted under the 1995
plan expire ten years after the date of grant. These plans have been superseded
by the 1996 Employee Stock Option Plan, and no future grants of options will be
made under these plans.

  1996 Employee Stock Option Plan:   In 1997, the Company's stockholders
approved an amendment to the 1996 Employee Stock Option Plan to increase the
number of Class A common shares available under the plan to 37,500,000 shares
from 4,525,000 shares. At December 31, 1998, after adjusting for option
exercises, the Company has reserved 37,277,305 shares of Class A common stock
for issuance to employees under the plan, which supersedes the 1992, 1993 and
1995 Incentive Stock Option Plans. The exercise price for options granted under
this plan is the fair market value of the Company's Class A common stock on the
day before the grant date (or 110% of the fair market value if the grantee
beneficially owns more than 10% of the outstanding Class A common stock). The
options granted expire ten years after the grant date (or five years after the
grant date if the grantee beneficially owns more than 10% of the outstanding
Class A common stock), and vest over periods determined by the Compensation
Committee; however, no more than $100,000 worth of stock covered by the options
may become exercisable in any calendar year by an individual employee. The 1996
Plan will terminate in March 2006, unless terminated earlier by the Board of
Directors.

  Directors' Stock Option Plan:   The Company has reserved 397,686 shares of
Class A common stock for issuance under the Directors' Plan to directors who are
not officers or employees of the Company. The Director's Plan was adopted and
approved by the stockholders in 1993 and amended and restated on March 28, 1996
to be a "formula" plan providing for an automatic grant of options to eligible
directors. Each eligible director who commences service on the Board of
Directors after the amendment and restatement of the plan will be granted an
initial option to purchase 10,000 shares of Class A common stock. An additional
option to purchase 5,000 shares of Class A common stock will be granted after
each of the next two annual meetings to each eligible director who remains for
the two-year period. Options granted under the Directors' Plan vest at a rate of
25% per year, on a cumulative basis, and expire seven years after the date of
grant (ten years after the date of grant for options granted under the amended
and restated plan). However, upon a change in control of the Company as defined
in the Directors' Plan, all options will become fully exercisable. The Company
has the right to repurchase any Class A common stock issued pursuant to the
exercise of an option granted under this plan that is offered for sale to an
individual who is not an employee or director of the Company. The Directors'
Plan will terminate in March 2006, unless terminated earlier by the Board of
Directors.

  The fair value of each grant under the Company's stock option plans is
estimated at the grant date using the Black-Scholes option-pricing model with
the following weighted-average assumptions for grants in 1998, 1997 and 1996,
respectively: no expected dividends, risk-free interest rates of 4.65%, 5.48%,
and 6.08%; price volatility of 59.39% in 1998, 48.63% in 1997 and 40% in 1996
and expected lives of 4 years for all three years.

  Employee Stock Purchase Plan: Under the stock purchase plan, employees may
purchase up to an aggregate of 1,000,000 shares of Class A common stock through
payroll deductions. Employees of the Company who have been employed more than
six months and who are regularly scheduled to work more than 20 hours per week
are eligible to participate in the plan, provided that they own less than five
percent of the total combined voting power of all classes of stock of the
Company. The purchase price for each share will be determined by the
Compensation Committee, but may not be less than 90% of the closing price of the
Class A common stock on the first or last trading day of the payroll deduction
period, whichever is lower. No employee may purchase in any calendar year Class
A common stock having an aggregate fair value in excess of $25,000. Upon
termination of employment, an employee other than a participating employee who
is subject to Section 16(b) under the Securities Exchange Act of 1934, as
amended, will be refunded all moneys in his or her account and the employee's
option to purchase shares will terminate. The plan will terminate in March 2006,
unless terminated earlier by the Board of Directors. The Company has implemented
this plan effective February 1, 1997. Under the plan, the Company sold 132,893
shares of Class A common stock in 1998 and 38,080 shares in 1997. The fair value
of the employees' purchase rights was calculated for disclosure purposes using
the Black-Scholes model with the following assumptions: an expected life of 12
months in 1998 and 11 months in 1997; a risk-free interest rate of 4.65% in 1998
and 5.40% in 1997; expected volatility of 59.39% in 1998 and 48.63% in 1997; and
no expected dividends. The fair value of each purchase right granted in 1998 was
$10.76 and in 1997 was $6.35.

  In addition, options to purchase shares of Class B common stock were granted
to a stockholder which had guaranteed borrowings under certain credit facilities
which were paid off with a portion of the proceeds from the Company's initial
public offering and subsequently canceled. These options have a weighted-average
exercise price of $1.79 and are fully vested at December 31, 1998.

Note 8.   CAPITAL STOCK INFORMATION AND INVESTOR AGREEMENT

  Public offerings:   On June 10, 1996, the Company undertook an initial public
offering of Class A common stock which yielded net proceeds of approximately
$258 million. On November 20, 1996, the Company completed an additional public
offering of Class A common stock which yielded net proceeds of approximately
$138 million in additional capital.

  Recapitalization:   In May 1997, the Company's stockholders approved an
increase in the authorized Class A common stock from 75,000,000 shares of $.01
par value stock to 250,000,000 shares of $.01 par value stock. In March 1996,
the Company's Board of Directors had authorized an increase in the authorized
Class A common stock to 75,000,000 shares of $.01 par value stock from
15,000,000 shares of $.01 par value stock and an increase in the authorized
Class B common stock to 22,000,000 shares of $.01 par value stock from
15,000,000 shares of $.01 par value stock. All Class B common stock has rights
identical to Class A common stock other than their voting rights, which are
equal to .40 vote per share. Each share of Class B common stock is convertible
into one share of Class A common stock at the option of the holder. The restated
Articles of Incorporation also authorizes the Board of Directors to issue up to
2,000,000 shares of $.01 par value preferred stock. The terms of the preferred
stock are determined at the time of issuance. No preferred shares were issued or
outstanding at December 31, 1998. Also in March 1996, the Board of Directors
declared a 3.75 to 1 stock split for both the Class A and Class B common stock
which was effected in the form of a stock dividend. All references to share and
per share amounts give retroactive effect to this stock split and
recapitalization.

  Stockholders' Agreement: Certain of the Company's principal stockholders have
entered into a Stockholders' Agreement, which amended and restated a prior
Investor Agreement, and became effective on September 24, 1997. This agreement
provides for the election of directors designated by certain principal
stockholders and prevents certain principal stockholders from disposing of any
equity securities of the Company for a period of one year unless consented to by
the Board of Directors. In addition, certain principal stockholders agreed that
for a period of two years they will not acquire any securities or options issued
by the Company, except as allowed by previous agreements or by the Board of
Directors.

     On November 18, 1998, the Company entered into a stockholders' agreement
(the "November 1998 Stockholders' Agreement") with Alliant Energy, Clark E. and
Mary E. McLeod, and Richard A. Lumpkin, Gail G. Lumpkin and several other
parties affiliated or related to Richard A. Lumpkin (collectively, the
"Lumpkins," and together with Alliant Energy and Clark E. and Mary E. McLeod,
the "Principal Stockholders").

     The November 1998 Stockholders' Agreement provides, among other things,
that:

 
     . until December 31, 2001, the Principal Stockholders will not sell or
       otherwise dispose of any of our equity securities, or any other
       securities convertible into or exercisable for such equity securities,
       beneficially owned by such Principal Stockholder without receiving the
       prior written consent of the Company's board of directors, except for
       permitted transfers as provided in the November 1998 Stockholders'
       Agreement

 
     . the Company's board of directors will determine on a quarterly basis
       commencing with the quarter ending December 31, 1998 and ending on
       December 31, 2001, the aggregate number, if any, of shares of Class A

NOTE 9.   CHANGE-OF-CONTROL AGREEMENTS

  Change-of-Control Agreements: The Company has entered into change-of-control
agreements with certain executive employees, which provide for certain payments
in connection with termination of employment after a change of control (as
defined within the agreements) of the Company. The change-of-control agreements
terminate on December 31, 2006 unless a change of control occurs during the six-
month period prior to December 31, 2006, in which case the agreements terminate
on December 31, 2007. The agreements provide that if an executive terminates his
or her employment within six months after a change of control or if the
executive's employment is terminated within 24 months after a change of control
in accordance with the terms and conditions set forth in the agreements, the
executive will be entitled to certain benefits. The benefits include cash
compensation, immediate vesting of outstanding stock options and coverage under
the Company's group health plan.

NOTE 10.   RETIREMENT PLANS AND POSTRETIREMENT BENEFITS

     CCI, a wholly owned subsidiary of the Company, maintains noncontributory
defined pension and death benefit plans covering substantially all of its
salaried and hourly employees. The pension benefit formula used in the
determination of pension cost is based on the highest five consecutive calendar
years' base earnings within the last ten calendar years immediately preceding
retirement or termination. It is CCI's policy to fund pension costs as they
accrue subject to any applicable Internal Revenue Code limitations.

     In 1997, the Company offered salaried plan participants a choice between
transferring their plan assets to the hourly defined benefit plan or
participating in the 1996 Employee Stock Option Plan, as the salaried defined
benefit plan was terminated effective April 1, 1998.  This plan change
substantially reduced the expected future benefits under the defined benefits
pension plans and has been reflected in the tables below.  As a result of the
termination of the salaried plan, the Company recognized a gain of $2.2 million.
The Company continues to maintain the defined benefit pension plan for
substantially all hourly employees of CCI.

NOTE 10.   RETIREMENT PLANS AND POSTRETIREMENT BENEFITS--(CONTINUED)

  In addition to providing pension benefits, CCI provides an optional retiree
medical program to its salaried and union retirees and spouses under age 65 and
common life insurance coverage for the salaried retirees. All retirees are
required to contribute to the cost of their medical coverage while the salaried
life insurance coverage is provided at no cost to the retiree.

and 1997, and the components of net periodic benefit costs and the weighted-
average assumption for 1998, 1997 and 1996, are as follows (in thousands):

NOTE 10.   RETIREMENT PLANS AND POSTRETIREMENT BENEFITS--(CONTINUED)

  The postretirement benefit obligation is calculated assuming that health-care
costs increased by 8% in 1998 and 7.5% in 1999, and that the rate of increase
thereafter (the health-care cost trend rate) will decline to 5% in 2004 and
subsequent years. The health-care cost trend rate has a significant effect on
the amounts reported for costs each year as well as on the accumulated
postretirement benefit obligation. For example, a one percentage point increase
each year in the health-care trend rate would have the following effects:

</TABLE>

  The weighted average discount rate used in determining the benefit obligation
was 7% in 1998.

  The postretirement medical and life insurance benefit plans have been modified
effective January 1, 1998 to provide benefits only to employees meeting certain
age and years of service requirements as of January 1, 1998.

  CCI also has a nonqualified deferred compensation plan, which allows selected
employees to defer a portion of any compensation received. Those deferred
amounts are invested in various funds at December 31, 1998 to provide assets and
accumulated earnings to offset the deferred compensation amounts due to the
participating employees.

  In addition, the Company has various 401(k) profit-sharing plans available to
eligible employees. The Company contributed approximately $2,007,000, $1,252,000
and $242,000 for the years ended December 31, 1998, 1997 and 1996, respectively.
An additional discretionary 1998 contribution of $1,500,000 was also made.

NOTE 12.   RELATED PARTY TRANSACTIONS

  The Company has entered into agreements with two stockholders that gives
certain rights-of-way to the Company for the construction of its
telecommunications network in exchange for capacity on the network.

  The Company provided and purchased services from various companies, the
principals of which are stockholders or directors of McLeodUSA Incorporated or
are affiliates. Revenues from services provided totaled $3,698,000, $1,018,000
and $254,000 and services purchased, primarily rent, legal services and database
verification services, totaled $3,065,000, $2,030,000 and $934,000 for the years
ended December 31, 1998, 1997 and 1996, respectively.

  In December 1998, the Company entered into a split dollar arrangement for life
insurance policies owned by the McLeod Family 1998 Special Trust on the joint
lives of Clark and Mary McLeod. The McLeod Family 1998 Special Trust agreed to
assign the policies to the Company as collateral for the premium payments. No
loans have been taken against these policies. In 1998, the premium payments paid
by the Company totaled $1,880,000. The aggregate face amount of the policies is
$113,000,000. The McLeod Family 1998 Special Trust is sole owner and beneficiary
of each policy. The Company has agreed with Clark and Mary McLeod that one of
the principle reasons for entering into this arrangement is to avoid any need
for their heirs to liquidate their holdings of Class A common stock at or soon
after the death of one or both of them. Clark and Mary McLeod have agreed to
restrictions on their ability to sell or otherwise dispose of their shares of
Class A common stock. The Company also paid premiums of $138,257 for a universal
life policy on Clark and Mary McLeod with a face value of $13,500,000. The
Company is the beneficiary of this policy.

  During 1997, the Company also acquired two condominium units from a Company
director for a total purchase price of $171,000 and purchased a 15,000 square
foot building, which is used as a support facility for its fiber optic network,
from a stockholder for a cash purchase price of $500,000.

  In addition, at December 31, 1998 the Company has two $75,000 notes receivable
from officers. The notes bear interest at the applicable federal interest rate
for mid-term loans.  One note requires interest-only payments for one year and
then annual $25,000 payments plus interest until paid in full.   The other note
requires annual $25,000 payments plus interest until paid in full.

(1)  The fourth quarter 1997 results include the operations of CCI, which was
acquired on September 24, 1997.

NOTE 14:  INFORMATION BY BUSINESS SEGMENT

     The Company operates predominantly in the business of providing local, long
distance and related communications services to end users and the sale of
advertising space in telephone directories. The two business segments have
separate management teams and infrastructures that offer different products and
services. The principal elements of these segments are to provide integrated
communications services, provide outstanding customer service, expand fiber
optic network, expand intra-city fiber network build, and publish and distribute
directories to local area subscribers.

     The Company evaluates the performance of its operating segments based on
earnings before interest, taxes, depreciation and amortization, excluding
general corporate expenses ("EBITDA"). The accounting policies of the reportable
segments are the same as those described in Note 1 of Notes to Consolidated
Financial Statements. Intersegment transfers are accounted for on an arm's
length pricing basis.

     Identifiable assets (excluding intersegment receivables) are the Company's
assets that are identified in each business segment. Corporate assets primarily
include cash and cash equivalents, investments in available-for-sale securities,
administrative headquarters and goodwill recorded primarily as a result of the
CCI merger in 1997.

     In 1998, 1997 and 1996, no single customer or group under common control
represented 10% or more of the Company's sales.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

NOTE 15:   EFFECTS OF NEW ACCOUNTING STANDARDS

  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use.  This statement provides guidance on
accounting for the costs of computer software developed or obtained for internal
use and is required to be adopted no later than our 1999 fiscal year.  The
Company plans to modify its method of capitalization of such costs by adopting
this statement prospectively on January 1, 1999.  The Company is currently
evaluating this statement but does not expect it to have a material impact on
its financial condition or results of operations.

  In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133").  SFAS 133 establishes accounting and reporting standards requiring that
every derivative instrument (including derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value.  SFAS 133 requires that changes in the derivative's
fair value be recognized currently in earnings unless specific hedge accounting
criteria are met.  Special accounting for qualifying hedges allows a
derivative's gains and losses to offset related results on the hedged item in
the income statement, and requires that a company must formally document,
designate and assess the effectiveness of transactions that receive hedge
accounting.

  SFAS 133 is effective for fiscal years beginning after June 15, 1999.  A
company may also implement SFAS 133 as of the beginning of any fiscal quarter
after issuance (that is, fiscal quarters beginning June 16, 1998 and
thereafter).  SFAS 133 cannot be applied retroactively.  SFAS 133 must be
applied to (a) derivative instruments and (b) derivative instruments embedded in
hybrid contracts that were issued, acquired or substantively modified after
December 31, 1997 (and, at the company's election, before January 1, 1998).

  The Company does not expect the impact of the adoption of SFAS 133 to be
material to its results of operations as it does not currently hold any
derivative instruments or engage in hedging activities.

NOTE 16:  SUBSEQUENT EVENTS

  The Ovation Merger Agreement.  On January 6, 1999, the Company entered into an
Agreement and Plan of Merger (the "Ovation Merger Agreement") with Ovation
Communications, Inc., a Delaware corporation ("Ovation"), and certain
stockholders of Ovation pursuant to which Ovation will be merged with and into a
newly formed wholly owned subsidiary of the Company (the "Ovation Merger").  As
a result of the Ovation Merger, (i) each share of Ovation's preferred stock will
be converted into the right to receive cash, and (ii) each share of Ovation's
common stock will be converted, at the election of the stockholder, into the
right to receive cash or shares of Class A common stock.  The amount of cash
into which each share of Ovation's preferred stock will be converted and the
amount of cash or number of shares of Class A common stock into which each share
of Ovation's common stock will be converted will be determined immediately prior
to consummation of the Ovation Merger in accordance with formulas specified in
the Ovation Merger Agreement.  The Company estimates that it will be required to
issue approximately 5.1 million shares of Class A common stock and to pay
approximately $141 million cash to effect the Ovation Merger.  The Company will
also assume approximately $95 million in Ovation debt.  In addition, under the
terms of the Ovation Merger Agreement, each option to purchase Ovation common
stock issued under Ovation's stock option plan will become or be replaced by an
option to purchase a number of shares of Class A common stock equal to the
number of shares of Ovation common stock that could have been purchased
(assuming full vesting) under the Ovation stock option multiplied by the
exchange ratio used to convert Ovation common stock into Class A common stock.

  Consummation of the Ovation Merger is subject to the satisfaction of certain
conditions, including (i) approval of the Ovation Merger Agreement and the
Ovation Merger by the stockholders of Ovation,

NOTE 16:   SUBSEQUENT EVENTS--(CONTINUED)

(ii) effectiveness of the registration statement registering the shares of Class
A common stock to be issued in the Ovation Merger, (iii) compliance with the
applicable provisions of the Hart-Scott-Rodino Antitrust Improvements Act of
1976 and the related waiting periods thereunder, (iv) receipt of specified
regulatory approvals, and (v) certain other customary conditions.  Both the
Company and Ovation may terminate the Ovation Merger Agreement if the Ovation
Merger has not been consummated by May 1, 1999.  Certain stockholders of Ovation
holding in the aggregate approximately 94% of the voting power attributable to
Ovation's common stock and preferred stock have agreed to vote all of their
shares in favor of the Ovation Merger at a meeting of the stockholders of
Ovation.

  In connection with the execution of the Ovation Merger Agreement, the Company
entered into a Revolving Credit Agreement with Ovation pursuant to which the
Company agreed to lend Ovation up to $20 million on a senior subordinated
unsecured basis.  In addition, pursuant to a stockholders' agreement, certain
Ovation stockholders agreed through December 31, 2001 to certain restrictions on
their ability to transfer the shares of Class A common stock that they will
receive in the Ovation Merger.

  Acquisition of Talking Directories, Inc. and Info America Phone Books, Inc.
On February 10, 1999, the Company acquired Talking Directories, Inc., a Michigan
corporation ("Talking Directories"), in exchange for 2.6 million shares of its
Class A common stock.  In a related and concurrent transaction, on February 10,
1999, the Company acquired Info America Phone Books, Inc., a Michigan
corporation ("Info America"), in exchange for 1.2 million shares of Class A
common stock.  The Company also paid outstanding obligations of Talking
Directories and Info America of approximately $27 million.

  1999 Senior Note Offering. In February 1999, the Company completed a private
offering of $500 million aggregate principal amount of our 8 1/8% Senior Notes
due February 15, 2009 (the "1999 Senior Notes"), yielding net proceeds of
approximately $487.8 million. The 1999 Senior Notes accrue interest at a rate of
8 1/8% per annum payable in cash semi-annually in arrears on February 15 and
August 15 of each year, commencing August 15, 1999.

  Acquisition of Dakota Telecommunications Group, Inc.  On March 5, 1999, the
Company acquired Dakota Telecommunications Group, Inc. in exchange for 1,375,000
shares of its Class A common stock and the assumption of approximately $31
million in Dakota Telecommunications Group, Inc. debt.

are delivered to the Trustee and, where it is hereby expressly required, to the
Company.  Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 7.01 hereof) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this

requesting such action, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when (a) either (i) all
outstanding Notes have been delivered to the Trustee for cancellation or (ii)
all such Notes not theretofore delivered to the Trustee for cancellation (A)
have become due and payable, (B) will become due and payable at their Stated
Maturity within one year or (C) are to be called for redemption within one year
under irrevocable arrangements satisfactory to the Trustee for the giving of
notice of redemption by the Trustee in the name, and at the expense, of the
Company, and the Company, in the case of (A), (B) or (C) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
the purpose an amount sufficient to pay and discharge the entire indebtedness on
such Notes, for principal (and premium, if any) and interest to the date of such

the Company to the Trustee under Section 7.07 hereof, and, if money shall have
been deposited with the Trustee in trust for the Holders pursuant to this
Section 1.06, the obligations of the Trustee under this Section 1.06 and Section
4.03 hereof shall survive.

     All money deposited with the Trustee pursuant to this Section 1.06 shall be
held in trust and applied by it, in accordance with the provisions of the Notes
and this Indenture, to the payment, either directly or through any Paying Agent,
to the Persons entitled thereto, of the principal (and premium, if any) and
interest for the payment of which such money has been deposited with the
Trustee.  If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Section 1.06 by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to this
Section 1.06 until such time as the Trustee or Paying Agent is permitted to
apply all such money or U.S. Government Obligations in accordance with this
Section 1.06; provided that, if the Company has made any payment of interest on
or principal of any Notes because of the reinstatement of its obligations, the
Company shall be subrogated 

                                      26

statement filed and declared effective, in each case (i) through (iv) upon the
terms and conditions set forth in the Registration Agreement (each such event
referred to in clauses (i) through (iv), a "Registration Default"), then
interest will accrue (in addition to any stated interest on the Notes) (the
"Step-Up") at a rate of 0.5% per annum, during the 90-day period from and
including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured and shall
increase by 0.25% per annum at the end of each subsequent 90-day period, but in
no event shall such rate exceed 2.00% per annum, in the aggregate regardless of
the number of Registration Defaults.  Interest accruing as a result of the Step-
Up is referred to herein as "Special Interest."  Accrued Special Interest, if
any, shall be paid semi-annually on February 15 and August 15 of each year; and
the amount of accrued Special Interest shall be determined on the basis of the
number of days actually elapsed.  Any accrued and unpaid interest (including
Special Interest) on this Note upon the issuance of an Exchange Note (as defined
in the Indenture) in exchange for this Note shall cease to be payable to the
Holder hereof but such accrued and unpaid interest (including Special Interest)

August 1 (whether or not a Business Day), as the case may be, immediately
preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this Note
(or one or more Predecessor Notes) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Notes not more than 15
calendar days and not less than 10 calendar days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Notes may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

     The principal of this Note shall accrue interest at the rate of 8.125% per
annum, and in the case of a default in payment of principal and premium, if any,
upon acceleration or redemption, in which case interest shall be payable
pursuant to the preceding paragraph on such overdue principal (and premium, if
any), such interest shall be payable on demand and, if not so paid on demand,
such interest shall itself bear interest at the rate of 9.125% per annum (to the
extent that the payment of such interest shall be legally enforceable), and
shall accrue from the date of such demand for payment to the date payment of
such interest has been made or duly provided for, and such interest on unpaid
interest shall also be payable on demand.

     Payment of the principal of (and premium, if any) and interest on this Note
will be made at the corporate trust office of the Trustee and at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, New York, and at any other office or agency maintained by
the Company for such purpose, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Note Register.

trustee under the Indenture).  The Notes are limited in aggregate principal
amount to $500,000,000.  Reference is hereby made to the Indenture and all
indentures supplemental thereto for a statement of the respective rights,

     The Notes are subject to redemption upon not less than 30 nor more than 60
days' notice by mail to each Holder of Notes to be redeemed at such Holder's
address appearing in the Note Register, in amounts of $1,000 or an integral
multiple of $1,000, at any time on or after February 15, 2004 and prior to

Holder on the relevant Regular Record Date to receive interest due on an
Interest Payment Date that is on or prior to the Redemption Date), if redeemed
during the 12-month period beginning February 15 of each of the years indicated
below:

               2007     100.000%          

and thereafter at a Redemption Price equal to 100% of the principal amount,
together in the case of any such redemption with accrued interest to but
excluding the Redemption Date, but interest installments whose Stated Maturity
is on or prior to such Redemption Date will be payable to the Holders of such
Notes, or one or more Predecessor Notes, of record at the close of business on
the relevant Regular Record Dates referred to on the face hereof, all as
provided in the Indenture.

     The Notes are further subject to redemption prior to February 15, 2002 only
in the event that the Company receives net proceeds from any sale of its Common
Stock in a Strategic Equity Investment on or before February 15, 2002, in which
case the Company may, at its option, use all or a portion of any such net
proceeds to redeem Notes in a principal amount of up to an aggregate amount
equal to 33 1/3% of the original principal amount of the Notes, provided,
however, that Notes in an amount equal to at least 66 2/3% of the original
principal amount of the Notes remain outstanding after such redemption.  Such
redemption must occur on a Redemption Date within 90 days of any such sale and
upon not less than 30 nor more than 60 days' notice by mail to each Holder of
Notes to be redeemed at such Holder's address appearing in the Note Register, in
amounts of $1,000 or an integral multiple of $1,000 at a Redemption Price equal
to 108.125% of the principal amount of the Notes so redeemed, plus accrued and
unpaid interest thereon (if any) to but excluding the Redemption Date.

     The Notes do not have the benefit of any sinking fund obligations.

     The Indenture provides that, subject to certain conditions, if (i) a Change
of Control (as defined in the Indenture) occurs or (ii) certain Excess Proceeds
are available to the Company 

                                      33
<PAGE>
 
as a result of any Asset Sale, the Company shall be required to make a Change of
Control Offer or an Asset Sale Offer, as the case may be, for all or a specified
portion of the Notes.

     [If not a Global Security insert -- In the event of redemption or purchase
pursuant to an Asset Sale Offer of this Note in part only, a new Note or Notes
of like tenor for the unredeemed or unpurchased portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.]

     [If a Global Security insert -- In the event of a deposit or withdrawal of
an interest in this Note (including upon an exchange, transfer, redemption or
repurchase of this Note in part only) effected in accordance with the Applicable
Procedures, the Note Registrar, upon receipt of notice of such event from the
Depositary's custodian for this Note, shall make an adjustment on its records to
reflect an increase or decrease of the outstanding principal amount of this Note
resulting from such deposit or withdrawal, as the case may be.]

     If an Event of Default shall occur and be continuing, the principal of all
the Notes may be declared due and payable in the manner and with the effect
provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of (i) the
entire indebtedness of this Note, or (ii) certain restrictive covenants and
Events of Default with respect to this Note, in each case upon compliance with
certain conditions set forth therein.

     Unless the context otherwise requires, the Original Notes (as defined in
the Indenture) and the Exchange Notes (as defined in the Indenture) shall
constitute one series for all purposes under the Indenture, including without
limitation, amendments, waivers, redemptions, Change of Control Offers and Asset
Sale Offers.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time outstanding.
The Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Notes at the time outstanding,
on behalf of the Holders of all the Notes, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to 

                                      34
<PAGE>
 
pay the principal of (and premium, if any) and interest on this Note at the
times, place and rate, and in the coin or currency, herein prescribed.

forth, the transfer of this Note is registrable in the Note Register, upon
surrender of this Note for registration of transfer at the office or agency of
the Company in the Borough of Manhattan, The City of New York, New York, duly

satisfactory to the Company and the Note Registrar duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes, of authorized denominations and like tenor and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Notes are
exchangeable for a like tenor and aggregate principal amount of Notes of a
different authorized denomination, as requested by the Holder surrendering the
same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

twelve 30-day months; provided, however, that Special Interest shall be computed
on the basis of a 365- or 366-day year, as the case may be, and the number of

AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

amount of Notes outstanding at any time shall not exceed $500,000,000.  The
Notes shall be executed on behalf of the Company by its Chief Executive Officer,
its President or any Executive Vice President and shall be attested by the
Company's Secretary or one of its Assistant Secretaries, in each case by manual
or facsimile signature.

     The Notes shall be authenticated by manual signature of an authorized
officer of the Trustee and shall not be valid for any purpose unless so
authenticated.

     In case any officer of the Company whose signature shall have been placed
upon any of the Notes shall cease to be such officer of the Company before
authentication of such Notes by the Trustee and the issuance and delivery
thereof, such Notes may, nevertheless, be authenticated by the Trustee and
issued and delivered with the same force and effect as though such Person had
not ceased to be such officer of the Company.

     Notwithstanding any other provision hereof, the Trustee shall authenticate
and deliver Notes only upon receipt by the Trustee of an Officers' Certificate
complying with Section 10.04 hereof with respect to satisfaction of all
conditions precedent contained in this Indenture to authentication and delivery
of such Notes.

     Upon compliance by the Company with the provisions of the previous
paragraph, the Trustee shall, upon receipt of a Company Order requesting such
action, authenticate Notes for original issuance in an aggregate principal
amount not to exceed $500,000,000.  Such Company Order shall specify the amount
of Notes to be authenticated and the date on which the Notes are to be
authenticated and shall further provide instructions concerning registration,
amounts for each Holder and delivery.

     A Note shall not be valid or entitled to any benefit under this Indenture
or obligatory for any purpose unless executed by the Company and authenticated
by the manual signature of 

                                      39
<PAGE>
 
the Trustee as provided herein. The signature of an authorized officer of the
Trustee shall be conclusive evidence, and the only evidence, that such Note has
been authenticated and delivered under this Indenture.

     The Trustee may appoint an authenticating agent reasonably acceptable to
the Company to authenticate the Notes.  Unless limited by the terms of such
appointment, an authenticating agent may authenticate Notes whenever the Trustee
may do so.   Each reference in this Indenture to authentication by the Trustee
includes authentication by such agent.   Any authenticating agent of the Trustee
shall have the same rights hereunder as any Registrar or Paying Agent.  The
Trustee shall not be liable for any failure to act of the authenticating agent
in performing any duty either required herein or authorized herein to be
performed by such person in accordance with the Indenture.

     SECTION II.6.   Note Registrar and Paying Agent.  The Company shall
                     -------------------------------                    
maintain, pursuant to Section 4.02 hereof, an office or agency where the Notes
may be presented for registration of transfer or for exchange.  The Company
shall cause to be kept at such office a register (the register maintained in
such office being herein sometimes referred to as the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Notes and of transfers of Notes entitled to be
registered or transferred as provided herein.  The Trustee, at its Corporate
Trust Office, is initially appointed "Note Registrar" for the purpose of
registering Notes and transfers of Notes as herein provided.  The Company may,
upon written notice to the Trustee, change the designation of the Trustee as
Note Registrar and appoint another Person to act as Note Registrar for purposes
of this Indenture.  If any Person other than the Trustee acts as Note Registrar,
the Trustee shall have the right at any time, upon reasonable notice, to inspect
or examine the Note Register and to make such inquiries of the Note Registrar as
the Trustee shall in its discretion deem necessary or desirable in performing
its duties hereunder.

     The Company shall enter into an appropriate agency agreement with any
Person designated by the Company as Note Registrar or Paying Agent that is not a
party to this Indenture, which agreement shall incorporate the provisions of the
Trust Indenture Act and shall implement the provisions of this Indenture that
relate to such Note Registrar or Paying Agent.  Prior to the designation of any
such Person, the Company shall, by written notice (which notice shall include
the name and address of such Person), inform the Trustee of such designation.
If the Company fails to maintain a Note Registrar or Paying Agent, the Trustee
shall act as such.

     Upon surrender for registration of transfer of any Note at an office or
agency of the Company designated for such purpose, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Initial Notes or Exchange Notes, as
the case may be, of any authorized denomination or denominations, of like tenor
and aggregate principal amount, all as requested by the transferor.

                                      40
<PAGE>
 
     Every Note presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company, the Trustee or the Note
Registrar) be duly endorsed, or be accompanied by a duly executed instrument of
transfer in form satisfactory to the Company, the Trustee and the Note
Registrar, by the Holder thereof or such Holder's attorney duly authorized in
writing.

     SECTION II.7.   Paying Agent to Hold Money in Trust.  On or prior to 10:00
                     -----------------------------------                       
a.m. on each due date of the principal, premium, or any payment of interest with
respect to any Note, the Company shall deposit with the Paying Agent a sum
sufficient to pay such principal, premium or interest when so becoming due.

     The Company shall require each Paying Agent (other than the Trustee) to
agree in writing that such Paying Agent, shall hold in trust for the benefit of
Holders or the Trustee all money held by such Paying Agent for the payment of
principal, premium, or interest with respect to the Notes, shall notify the
Trustee of any default by the Company in making any such payment and at any time
during the continuance of any such default, upon the written request of the
Trustee, shall forthwith pay to the Trustee all sums held in trust by such
Paying Agent.

     The Company at any time may require a Paying Agent to pay all money held by
it to the Trustee and to account for any funds disbursed by such Paying Agent.
Upon complying with this Section 2.07, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

     SECTION II.8.   Registration, Registration of Transfer and Exchange.
                     --------------------------------------------------- 

     (a)  At the option of the Holder, and subject to the other provisions of
this Section 2.08, Notes may be exchanged for other Notes of any authorized
denominations and of a like tenor and aggregate principal amount, upon surrender
of the Notes to be exchanged at such office or agency.  Whenever any Notes are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Notes which the Holder making the exchange is
entitled to receive.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
(subject to the provisions in the Original Notes regarding the payment of
Special Interest) entitled to the same benefits under this Indenture, as the
Notes surrendered upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Note Registrar duly executed, by the Holder thereof or his
attorney duly authorized in writing.

                                      41
<PAGE>
 
     No service charge shall be made to the Holder for any registration of
transfer or exchange of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes, other than
exchanges pursuant to Sections 2.11, 3.06 or 9.06 hereof or in accordance with
any offer pursuant to Section 4.07 or 4.08 hereof not involving any transfer.

     Any holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected through a book entry system maintained by the holder of such
Global Security (or its agent) and the ownership of a beneficial interest in the
Note shall be reflected in a book entry.

     The Company shall not be required (i) to issue, register the transfer of or
exchange any Note during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of Notes selected for
redemption under Section 3.03 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any Note so
selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part.

     (b)  Certain Transfers and Exchanges.  Notwithstanding any other provision
          -------------------------------                                      
of this Indenture or the Notes, transfers and exchanges of Notes and beneficial
interests in a Global Security of the kinds specified in this Section 2.08(b)
shall be made only in accordance with this Section 2.08(b).

          (i) Restricted Global Security to Regulation S Global Security.  If
              ----------------------------------------------------------     
     the owner of a beneficial interest in the Restricted Global Security wishes
     at any time to transfer such interest to a Person who wishes to acquire the
     same in the form of a beneficial interest in the Regulation S Global
     Security, such transfer may be effected only in accordance with the
     provisions of this Clause (b)(i) and Clause (b)(vii) below and subject to
     the Applicable Procedures.  Upon receipt by the Trustee, as Note Registrar,
     of (A) an order given by the Depositary or its authorized representative
     directing that a beneficial interest in the Regulation S Global Security in
     a specified principal amount be credited to a specified Agent Member's
     account and that a beneficial interest in the Restricted Global Security in
     an equal principal amount be debited from another specified Agent Member's
     account and (B) a Regulation S Certificate, satisfactory to the Trustee and
     duly executed by the owner of such beneficial interest in the Restricted
     Global Security or his attorney duly authorized in writing, then the
     Trustee, as Note Registrar but subject to Clause (b)(vii) below, shall
     reduce the principal amount of the Restricted Global Security and increase
     the principal amount of the Regulation S Global Security by such specified
     principal amount as provided in Section 2.08(d)(3) hereof.

          (ii)  Regulation S Global Security to Restricted Global Security.  If
                ----------------------------------------------------------     
     the owner of a beneficial interest in the Regulation S Global Security
     wishes at any time to transfer such interest to a Person who wishes to
     acquire the same in the form of a beneficial interest in the Restricted
     Global Security, such transfer may be effected only in accordance with this
     Clause (b)(ii) and subject to the Applicable Procedures.  Upon receipt by
     the Trustee, as Note Registrar, of (A) an order given by the Depositary or
     its authorized representative directing that a beneficial interest in the
     Restricted Global Security in a specified principal amount be credited to a

     occur during the Restricted Period, a Restricted Notes Certificate,
     satisfactory to the Trustee and duly executed by the owner of such

     increase the principal amount of the Restricted Global Security by such
     specified principal amount as provided in Section 2.08(d)(3) hereof.

     ----------------------------                                               
     Holder of a Restricted Note (other than a Global Security) wishes at any
     time to transfer all or any portion of such Restricted Note to a Person who
     wishes to take delivery thereof in the form of a beneficial interest in the
     Restricted Global Security or the Regulation S Global Security, such
     transfer may be effected only in accordance with the provisions of this
     Clause (b)(iii) and Clause (b)(vii) below and subject to the Applicable

     satisfactory to the Trustee directing that a beneficial interest in the
     Restricted Global Security or Regulation S Global Security in a specified
     principal amount not greater than the principal amount of such Note be
     credited to a specified Agent Member's account and (B) a Restricted Notes
     Certificate (or the completion of the Certificate of Transfer on the Note),
     if the specified account is to be credited with a beneficial interest in

     completion of the Certificate of Transfer on the Note), if the specified
     account is to be credited with a beneficial interest in the Regulation S
     Global Security, in either case satisfactory to the Trustee and duly

               ---------------------------------------------- ------------------
     Regulation S Global Security.  Subject to Section 2.08(d)(2) hereof, if the
     ----------------------------                                               
     Holder of a Regulation S Note (other than a Global Security) wishes at any
     time to transfer all or any portion of such Regulation S Note to a Person
     who wishes to acquire the same in the form of a beneficial interest in the
     Restricted Global Security or the Regulation S Global Security, such
     transfer may be effected only in accordance with this Clause (b)(iv) and
     Clause (b)(vii) below and subject to the Applicable Procedures.  Upon
     receipt by the Trustee, as Note Registrar, of (A) such Regulation S Note as
     provided in Section 2.08(a) hereof and instructions satisfactory to the
     Trustee directing that a beneficial interest in the Restricted Global
     Security or Regulation S Global Security in a specified principal amount
     not greater than the principal amount of such Note be credited to a
     specified Agent Member's account and (B) if the transfer is to occur during
     the Restricted Period and the specified account is to be credited with a
     beneficial interest in the Restricted Global Security, a Restricted Notes
     Certificate (or the completion of the Certificate of Transfer on the Note)
     satisfactory to the Trustee and duly executed by such Holder or his
     attorney duly authorized in writing, then the Trustee, as Note Registrar
     but subject to Clause (b)(vii) below, shall cancel such Regulation S Note
     (and issue a new Regulation S Note in respect of any untransferred portion

          (v)  Non-Global Security to Non-Global Security.  A Note that is not a
               ------------------------------------------

          (vi) Exchanges between Global Security and Non-Global Security.  A
               ---------------------------------------------------------    
     beneficial interest in a Global Security may be exchanged for a Note that
     is not a Global Security as provided in Section 2.08(d)(2) hereof, provided
     that, if such interest is a beneficial interest in the Restricted Global
     Security, or if such interest is a beneficial interest in the Regulation S
     Global Security and such exchange is to occur during the Restricted 

                                      44
<PAGE>
 
     Period, then such interest shall be exchanged for a Restricted Note
     (subject in each case to Section 2.08(c) hereof). A Note that is not a
     Global Security may be exchanged for a beneficial interest in a Global
     Security only if (A) such exchange occurs in connection with a transfer

     is a Regulation S Note and such exchange occurs after the Restricted
     Period.

     ------------------------------                                            
     cause the Depositary to ensure that, until the expiration of the Restricted
     Period, beneficial interests in the Regulation S Global Security may be
     held only in or through accounts maintained at the Depositary by Euroclear
     or Cedel (or by Agent Members acting for the account thereof), and no
     person shall be entitled to effect any transfer or exchange that would
     result in any such interest being held otherwise than in or through such an
     account; provided that this Clause (b)(vii) shall not prohibit any transfer
     or exchange of such an interest in accordance with Clause (b)(ii) or (vi)
     above.

     (c)  Securities Act Legends.  Rule 144A Notes, Other Notes and their
          ----------------------                                         
respective Successor Notes shall bear a Restricted Note Legend, and the
Regulation S Notes and their Successor Notes shall bear a Regulation S Legend,
subject to the following:

          (i)   subject to the following Clauses of this Section 2.08(c), a Note
     or any portion thereof which is exchanged, upon transfer or otherwise, for
     a Global Security or any portion thereof shall bear the Securities Act
     Legend borne by such Global Security while represented thereby;

          (ii)  subject to the following Clauses of this Section 2.08(c), a new
     Note which is not a Global Security and is issued in exchange for another
     Note (including a Global Security) or any portion thereof, upon transfer or
     otherwise, shall bear the Securities Act Legend borne by such other Note,
     provided that, if such new Note is required pursuant to Section 2.08(b)(v)
     or (vi) hereof to be issued in the form of a Restricted Note, it shall bear
     a Restricted Note Legend and, if such new Note is so required to be issued
     in the form of a Regulation S Note, it shall bear a Regulation S Legend;

          (iii) Registered Notes shall not bear a Securities Act Legend;

          (iv)  at any time after the Notes may be freely transferred without
     registration under the Securities Act or without being subject to transfer
     restrictions pursuant to the Securities Act, a new Note which does not bear
     a Securities Act Legend may be issued in exchange for or in lieu of a Note
     (other than a Global Security) or any portion thereof which bears such a
     legend if the Trustee has received an Unrestricted Note Certificate,
     satisfactory to the Trustee and duly executed by the Holder of such
     legended Note or his attorney duly authorized in writing, and after such
     date and 

                                      45
<PAGE>
 
     receipt of such certificate, the Trustee shall authenticate and
     deliver such a new Note in exchange for or in lieu of such other Note as
     provided in this Article II;

          (v)   a new Note which does not bear a Securities Act Legend may be
     issued in exchange for or in lieu of a Note (other than a Global Security)
     or any portion thereof which bears such a legend if, in the Company's
     judgment, placing such a legend upon such new Note is not necessary to
     ensure compliance with the registration requirements of the Securities Act,
     and the Trustee, at the direction of the Company, shall authenticate and
     deliver such a new Note as provided in this Article II; and

          (vi)  notwithstanding the foregoing provisions of this Section
     2.08(c), a Successor Note of a Note that does not bear a particular form of
     Securities Act Legend shall not bear such form of legend unless the Company
     has reasonable cause to believe that such Successor Note is a "restricted
     security" within the meaning of Rule 144, in which case the Trustee, at the
     direction of the Company, shall authenticate and deliver a new Note bearing
     a Restricted Note Legend in exchange for such Successor Note as provided in
     this Article II.

     (d)  The provisions of Clauses (1), (2), (3), (4) and (5) below shall apply
only to Global Securities:

          (1)   Each Global Security authenticated under this Indenture shall be
     registered in the name of the Depositary or a nominee thereof and delivered
     to the Depositary or a nominee thereof or custodian therefor, and each such
     Global Security shall constitute a single Note for all purposes of this
     Indenture.

          (2)   Notwithstanding any other provision in this Indenture, no Global
     Security may be exchanged in whole or in part for Notes registered, and no
     transfer of a Global Security in whole or in part may be registered, in the
     name of any Person other than the Depositary or a nominee thereof unless
     (i) the Depositary notifies the Company that it is unwilling or unable to
     continue as a depositary for such Global Security or if at any time the
     Depositary ceases to be a clearing agency registered under the Exchange
     Act, and a successor depositary is not appointed by the Company within 90
     days, (ii) the Company 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 (iii) there shall
     have occurred and be continuing an Event of Default with respect to the
     Notes represented by such Global Security.

          (3)   If any Global Security is to be exchanged for other Notes or
     canceled in whole, it shall be surrendered by or on behalf of the
     Depositary or its nominee to the Trustee, as Note Registrar, for exchange
     or cancellation as provided in this Article II.  If any Global Security is
     to be exchanged for other Notes or canceled in part, or if 

                                      46
<PAGE>
 
     another Note is to be exchanged in whole or in part for a beneficial
     interest in any Global Security, then either (i) such Global Security shall
     be so surrendered for exchange or cancellation as provided in this Article
     II or (ii) the principal amount thereof shall be reduced or increased by an
     amount equal to the portion thereof to be so exchanged or canceled, or
     equal to the principal amount of such other Note to be so exchanged for a
     beneficial interest therein, as the case may be, by means of an appropriate
     adjustment made on the records of the Trustee, as Note Registrar, whereupon
     the Trustee, in accordance with the Applicable Procedures, shall instruct
     the Depositary or its authorized representative to make a corresponding
     adjustment to its records. Upon any such surrender or adjustment of a
     Global Security, the Trustee shall, subject to Section 2.08(d)(2) hereof
     and as otherwise provided in this Article II, authenticate and deliver any
     Notes issuable in exchange for such Global Security (or any portion
     thereof) to or upon the order of, and registered in such names as may be
     directed by, the Depositary or its authorized representative. Upon the
     request of the Trustee in connection with the occurrence of any of the
     events specified in the preceding paragraph, the Company shall promptly
     make available to the Trustee a reasonable supply of Notes that are not in
     the form of Global Securities. The Trustee shall be entitled to rely upon
     any order, direction or request of the Depositary or its authorized
     representative which is given or made pursuant to this Article II if such
     order, direction or request is given or made in accordance with the
     Applicable Procedures.

          (4)  Every Note authenticated and delivered upon registration of
     transfer of, or in exchange for or in lieu of, a Global Security or any
     portion thereof, whether pursuant to this Section, Section 2.05, 2.09,
     3.06, 4.07, 4.08 or 9.06 hereof or otherwise, shall be authenticated and
     delivered in the form of, and shall be, a Global Security, unless such Note
     is registered in the name of a Person other than the Depositary or a
     nominee thereof.

          (5)  None of the Company, the Trustee, any agent of the Trustee, any
     Paying Agent or the Note Registrar will have any responsibility or
     liability for any aspect of the Depository's records (or the records of the
     participant of such Depository) relating to or payments made on account of
     beneficial ownership interests of a Global Security or for maintaining,
     supervising or reviewing any records of the Depository relating to such
     beneficial ownership interests.

     SECTION II.9.  Replacement Notes.  If any mutilated Note is surrendered to
                    -----------------                                          
the Trustee, the Company shall execute and upon its written request the Trustee
shall authenticate and deliver, in exchange for any such mutilated Note, a new
Note containing identical provisions and of like principal amount, bearing a
number not contemporaneously outstanding.

                                      47

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Note and (ii) such
security or indemnity as may be required by them to save either of them and any
agent of each of them harmless, then, in the absence of notice to the Company or
the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Note, a new Note
containing identical provisions and of like principal amount, bearing a number
not contemporaneously outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 2.09, the Company may
require the payment by the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 2.09 in lieu of any
destroyed, lost or stolen Note shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Notes duly issued hereunder.

     The provisions of this Section 2.09 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     SECTION 2.10.  Outstanding Notes.  Notes outstanding at any time are all
                    -----------------                                        
Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation and those described in this Section 2.10 as not
outstanding.  A Note does not cease to be outstanding because the Company or an
Affiliate of the Company holds such Note.

     If a Note is replaced pursuant to Section 2.09 hereof, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that such replaced Note is held by a bona fide purchaser.

     If the Paying Agent segregates and holds in trust, in accordance with this
Indenture, on a redemption date or Maturity date money sufficient to pay all
principal, premium, if any, and interest payable on that date with respect to
the Notes (or portions thereof) to be redeemed or maturing, as the case may be,
then on and after that date such Notes (or such portions thereof) shall cease to
be outstanding and interest on them shall cease to accrue.

                                      48
<PAGE>
 
     In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent or any amendment,
modification or other change to this Indenture, Notes held or beneficially owned
by the Company or a Restricted Subsidiary of the Company or by an Affiliate of
the Company or a Restricted Subsidiary of the Company or by agents of any of the
foregoing shall be disregarded, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent or any amendment, modification or other change to this Indenture,
only Notes which a Trust Officer knows are so owned shall be so disregarded.
Notes so owned which have been pledged in good faith shall not be disregarded if
the pledgee establishes to the satisfaction of the Trustee such pledgee's right
so to act with respect to the Notes and that the pledgee is not the Company or
an Affiliate of the Company or any of their agents.

     SECTION 2.11.  Temporary Notes.  Pending the preparation of definitive
                    ---------------                                        
Notes, the Company may execute, and the Trustee shall authenticate, temporary
notes ("Temporary Notes") which are printed, lithographed, or otherwise
produced, substantially of the tenor of the definitive Notes in lieu of which
they are issued and with such appropriate insertions, omissions, substitutions
and other variations.

     If Temporary Notes are issued, the Company shall cause definitive Notes to
be prepared without unreasonable delay.  After the preparation of definitive
Notes, the Temporary Notes shall be exchangeable for definitive Notes upon
surrender of the Temporary Notes to the Trustee, without charge to the Holder.
Until so exchanged, Temporary Notes will evidence the same debt and will be
entitled to the same benefits under this Indenture as the definitive Notes in
lieu of which they have been issued.

     SECTION 2.12.  Cancellation.  The Company at any time may deliver Notes to
                    ------------                                               
the Trustee for cancellation.  The Note Registrar and the Paying Agent shall
forward to the Trustee any Notes surrendered to them for registration of
transfer, exchange, purchase or payment.  The Trustee shall cancel all Notes
surrendered for registration of transfer, exchange, purchase, payment or
cancellation and shall destroy such canceled Notes unless the Company shall by
Company Order otherwise direct. The Company may not issue new Notes to replace
Notes that have been delivered to the Trustee for cancellation.

     SECTION 2.13.  Payment of Interest; Interest Rights Preserved.  Interest on
                    ----------------------------------------------              
any Note which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Note is
registered at the close of business on the Regular Record Date for such interest
payment, which shall be the February 1 or August 1 (whether or not a Business
Day) immediately preceding such Interest Payment Date.

     Any interest on any Note which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to 

                                      49
<PAGE>
 
be payable to the registered Holder on the relevant Regular Record Date, and,
except as hereinafter provided, such Defaulted Interest, and any interest
payable on such Defaulted Interest, may be paid by the Company, at its election,
as provided in clause (a) or (b) below:

          (a)  The Company may elect to make payment of any Defaulted Interest,
     and any interest payable on such Defaulted Interest, to the Persons in
     whose names the Notes are registered at the close of business on a Special
     Record Date for the payment of such Defaulted Interest, which shall be
     fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on the
     Notes and the date of the proposed payment, and at the same time the
     Company shall deposit with the Trustee an amount of money equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as provided in this Clause.  Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 calendar days and not less than 10 calendar days prior
     to the date of the proposed payment and not less than 10 calendar days
     after the receipt by a Trust Officer of the Trustee of the notice of the
     proposed payment.  The Trustee shall promptly notify the Company of such
     Special Record Date and, in the name and at the expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be sent, first class mail, postage
     prepaid, to each Holder at such Holder's address as it appears in the Note
     Register, not less than 10 calendar days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been mailed as aforesaid, such Defaulted
     Interest shall be paid to the Persons in whose names the Notes are
     registered at the close of business on such Special Record Date and shall
     no longer be payable pursuant to the following clause (b).

          (b)  The Company may make payment of any Defaulted Interest, and any
     interest payable on such Defaulted Interest, on the Notes in any other
     lawful manner not inconsistent with the requirements of any securities
     exchange on which the Notes may be listed, and upon such notice as may be
     required by such exchange, if, after notice given by the Company to the
     Trustee of the proposed payment pursuant to this clause, such manner of
     payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section 2.13, each Note
delivered under this Indenture upon registration of transfer of, or in exchange
for, or in lieu of, any other Note, shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Note.

     SECTION 2.14.  Authorized Denominations.  The Notes shall be issuable in
                    ------------------------                                 
minimum denominations of $1,000 and any integral multiple thereof.

     SECTION 2.15.  Computation of Interest.  Interest on the Notes shall be
                    -----------------------                                 
computed on the basis of a 360-day year of twelve 30-day months; provided that
Special Interest shall be computed on the basis of a 365- or 366-day year, as
the case may be, and the number of days actually elapsed from the date Special
Interest commences to accrue to but not including the date on which Special
Interest ceases to accrue.

     SECTION 2.16.  Persons Deemed Owners.  Prior to the due presentation for
                    ---------------------                                    
registration of transfer of any Note, the Company, the Trustee, the Paying
Agent, the Note Registrar or any co-registrar may deem and treat the person in
whose name Note is registered as the absolute owner of such Note for the purpose
of receiving payment of principal of, premium, if any, and interest on such Note
and for all other purposes whatsoever, whether or not such Note is overdue, and
none of the Company, the Trustee, the Paying Agent, the Note Registrar or any
co-Registrar shall be affected by notice to the contrary.

     SECTION 2.17.  CUSIP Numbers.  The Company, in issuing the Notes, may use
                    -------------                                             
"CUSIP" and "ISIN" numbers for each series of Notes and, if so, the Trustee
shall use the relevant CUSIP and ISIN numbers in any notices to Holders as a
convenience to such Holders; provided that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP and ISIN
numbers printed in the notice or on the Notes and that reliance may be placed
only on the other identification numbers printed on the Notes.  The Company
shall promptly notify the Trustee of any change in any CUSIP or "ISIN" numbers
used.

     SECTION 2.18.  Holder Lists.  The Trustee shall preserve in as current a
                    ------------                                             
form as is reasonably practicable the most recent list available to it of the
names and addresses of Holders and shall otherwise comply with Trust Indenture
Act (S) 312(a).  If the Trustee is not the Note Registrar, the Company shall
furnish to the Trustee as of each Regular Record Date and at such other times as
the Trustee may request in writing a list in such form and as of such date as
the Trustee may reasonably require of the names and addresses of Holders,
including the aggregate principal amount of Notes held by each Holder.

                                 ARTICLE III.

                                  REDEMPTION

     SECTION III.1. Notice to Trustee.  If the Company elects to redeem Notes
                    -----------------                                        
pursuant to paragraph two or three of the reverse side of the Notes, it shall
notify the Trustee in writing of the Redemption Date and the principal amount of
Notes to be redeemed.  The Company shall give each such notice to the Trustee at
least 60 calendar days prior to the Redemption Date 

                                      51
<PAGE>
 
unless the Trustee consents in writing to a shorter period. Such notice shall be
accompanied by an Officers' Certificate and an Opinion of Counsel from the
Company to the effect that such redemption will comply with any conditions to
such redemption set forth herein and in the Notes.

     SECTION III.2.  Selection of Notes to be Redeemed.  If less than all the
                     ---------------------------------                       
Notes are to be redeemed at any time, the Trustee shall select the Notes to be
redeemed by lot, on a pro rata or other basis as it shall deem fair and
appropriate; provided that the Trustee may select for redemption in part only
Notes in denominations larger than $1,000.  In selecting Notes to be redeemed
pursuant to this Section 3.02, the Trustee shall make such adjustments,
reallocations and eliminations as it shall deem proper so that the principal
amount of each Note to be redeemed shall be $1,000 or an integral multiple
thereof, by increasing, decreasing or eliminating any amount less than $1,000
which would be allocable to any Holder.  If the Notes to be redeemed are
certificated Notes, the certificated Notes to be redeemed shall be selected by
the Trustee by prorating, as nearly as may be, the principal amount of
certificated Notes to be redeemed among the Holders of certificated Notes
registered in their respective names.  The Trustee in its discretion may
determine the particular Notes (if there are more than one) registered in the
name of any Holder which are to be redeemed, in whole or in part. Provisions of
this Indenture that apply to Notes called for redemption also apply to portions
of Notes called for redemption.  The Trustee shall notify the Company promptly
of the Notes or portions of Notes to be redeemed.

     SECTION III.3.  Notice of Redemption.  At least 30 calendar days but not
                     --------------------                                    
more than 60 calendar days before a Redemption Date, the Company shall send a
notice of redemption, first class mail, postage prepaid, to Holders of Notes to
be redeemed at the addresses of such Holders as they appear in the Note
Register.

     The notice shall identify the Notes to be redeemed and shall state:

          (a)  the Redemption Date;

          (b)  the Redemption Price (and shall specify the portion of such
     Redemption Price that constitutes the amount of accrued and unpaid interest
     to be paid, if any);

          (c)  the name and address of the Paying Agent;

          (d)  that the Notes called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price;

          (e)  if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the Redemption
     Date, a new Note or Notes in principal amount equal to the unredeemed
     portion will be issued;

                                      52
<PAGE>
 
          (f)  if fewer than all the outstanding Notes are to be redeemed, the
     identification and principal amounts of the particular Notes to be
     redeemed;

          (g)  that, unless the Company defaults in making the redemption
     payment, interest on the Notes (or portions thereof) called for redemption
     shall cease and such Notes (or portions thereof) shall cease to accrue
     interest on and after the Redemption Date;

          (h)  the paragraph of the Notes pursuant to which the Notes are being
     called for redemption; and

          (i)  any other information necessary to enable Holders to comply with
     the notice of redemption.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense.  In such event, the Company
shall provide the Trustee with the information required by this Section 3.03 in
a timely manner.

     SECTION III.4.  Effect of Notice of Redemption.  Once notice of redemption
                     ------------------------------                            
is mailed, Notes called for redemption shall become due and payable on the
Redemption Date and at the Redemption Price stated in such notice.  Upon
surrender to the Paying Agent, such Notes shall be paid at the Redemption Price
stated in such notice.  Failure to give notice or any defect in the notice to
any Holder shall not affect the validity of the notice to any other Holder.

     SECTION III.5.  Deposit of Redemption Price.  On or prior to 10:00 a.m.,
                     ---------------------------                             
New York City time, on each Redemption Date, the Company shall deposit with the
Paying Agent (or, if the Company, one of its Subsidiaries or any of their
Affiliates is the Paying Agent, the Paying Agent shall segregate and hold in
trust for the benefit of the Holders) money, in federal or other immediately
available funds, sufficient to pay the Redemption Price on all Notes to be
redeemed on that date other than Notes or portions of Notes called for
redemption on such date which have been delivered by the Company to the Trustee
for cancellation.

     So long as the Company complies with the preceding paragraph and the other
provisions of this Article III, interest on the Notes to be redeemed on the
applicable Redemption Date shall cease to accrue from and after such date and
such Notes or portions thereof shall be deemed not to be entitled to any benefit
under this Indenture except to receive payment of the Redemption Price on the
Redemption Date.  If any Note called for redemption shall not be so paid upon
surrender for redemption, then, from the Redemption Date until such principal is
paid, interest shall be paid on the unpaid principal and, to the extent
permitted by law, on any accrued but unpaid interest thereon, in each case at
the rate prescribed therefor by such Notes.

     SECTION III.6.  Notes Redeemed in Part.  Upon surrender and cancellation of
                     ----------------------                                     
a Note that is redeemed in part, the Company shall issue and the Trustee shall
authenticate and deliver to the surrendering Holder (at the Company's expense) a
new Note equal in principal amount to the unredeemed portion of the Note
surrendered and canceled; provided that each such Note shall be in a principal
amount of $1,000 or an integral multiple thereof.


                                  ARTICLE IV.

                                   COVENANTS

     SECTION IV.1.  Payment of Notes.  The Company shall promptly pay the
                    ----------------                                     
principal of, premium, if any, and interest on, the Notes on the dates and in
the manner provided in the Notes and in this Indenture.  Principal, premium and
interest shall be considered paid on the date due if, on such date, the Trustee
or the Paying Agent holds in accordance with this Indenture money sufficient to
pay all principal, premium and interest then due.

     To the extent lawful, the Company shall pay interest on (i) any overdue
principal of (and premium, if any, on) the Notes, at the interest rate borne on
the Notes, plus 1% per annum, and (ii) Defaulted Interest (without regard to any
applicable grace period), at the same rate.  The Company's obligation pursuant
to the previous sentence shall apply whether such overdue amount is due at its
Stated Maturity, as a result of the Company's obligations pursuant to Section
3.05, Section 4.07 or Section 4.08 hereof, or otherwise.

     SECTION IV.2.  Maintenance of Office or Agency.  The Company shall maintain
                    -------------------------------                             
in the Borough of Manhattan, The City of New York, an office or agency where
Notes may be presented or surrendered for payment, where Notes may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served.  The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency.  If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee its agent to
receive all presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies (in or outside of The City of New York) where the Notes may be
presented or surrendered for any or all of such purposes, and may from time to
time rescind such designations; provided that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in The City of New York, for such purposes.  The Company shall give
prompt written notice to the Trustee of any such designation and any change in
the location of any such other office or agency.

     SECTION IV.3.  Money for the Note Payments to be Held in Trust.  If the
                    -----------------------------------------------         
Company, any Subsidiary of the Company or any of their respective Affiliates
shall at any time act as Paying Agent with respect to the Notes, such Paying
Agent shall, on or before each due date of the principal of (and premium, if
any) or interest on any of the Notes, segregate and hold in trust for the
benefit of the Persons entitled thereto money sufficient to pay the principal
(and premium, if any) or interest so becoming due until such money shall be paid
to such Persons or otherwise disposed of as herein provided, and shall promptly
notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents with respect to
the Notes, it shall, prior to or on each due date of the principal of (and
premium, if any) or interest on any of the Notes, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Paying Agent shall promptly notify the Trustee of the
Company's action or failure so to act.

     SECTION IV.4.  Corporate Existence.  Subject to the provisions of Article
                    -------------------                                       
IV and Article V hereof, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect the corporate existence,
rights (charter and statutory) and franchises of the Company and each of its
Restricted Subsidiaries; provided that the Company and any such Restricted
Subsidiary shall not be required to preserve the corporate existence of any such
Restricted Subsidiary or any such right or franchise if the Board of Directors
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and provided further that any Restricted
Subsidiary may consolidate with, merge into, or sell, convey, lease or otherwise
dispose of all of its property and assets to the Company or any wholly owned
Restricted Subsidiary.

     SECTION IV.5.  Maintenance of Property.  The Company shall cause all
                    -----------------------                              
Property used or useful in the conduct of its business or the business of any of
its Restricted Subsidiaries and material to the Company and its 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 shall
cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as, in the judgment of the Company, may be necessary
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided that nothing in this Section
4.05 shall prevent the Company from discontinuing the operation or maintenance
of any of such Property if such discontinuance is, in the judgment of the
Company, desirable in the conduct of its business or the business of any of its
Restricted Subsidiaries.

discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all material taxes, assessments and governmental charges levied
or imposed upon the Company or any of its Restricted Subsidiaries or upon the
income, profits or Property of the Company or any of its Restricted Subsidiaries

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 by 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.

Control Offer"), at a purchase price (the "Change of Control Purchase Price") in
cash equal to 101 percent of the principal amount of such Notes (or portions

     pursuant to provisions substantially similar to those described in Section

     redemption of Preferred Stock of a Restricted Subsidiary of the Company,
     such Preferred Stock may only be exchanged for or redeemed with Preferred
     Stock of such Restricted Subsidiary; and

          (ix)   Indebtedness Incurred or Preferred Stock issued by a Restricted

          (i)    no Default or Event of Default shall have occurred and be
     continuing or shall occur as a consequence thereof;

          (ii)   after giving effect, on a pro forma basis, to such Restricted

     basis, the aggregate amount expended (the amount so expended, if other than
     cash, to be determined in good faith by a majority of the disinterested
     members of the Board of Directors, whose determination shall be conclusive
     and evidenced by a resolution thereof) or declared for all Restricted
     Payments after the Issue Date does not exceed the sum of (A) 50% of the

     immediately preceding the Issue Date and ending on the last day of the

     the definition of "Investments" in Section 1.01 hereof), not to exceed in
     the case of any Person the amount of Investments previously made subsequent
     to the Issue Date by the Company or any Restricted Subsidiary in such
     Person and which was treated as a Restricted Payment; provided that the
     Company or a Restricted Subsidiary of the Company may make any Restricted
     Payment with the aggregate net proceeds received after the date of the
     Indenture, including the fair value of property other than cash (determined

          (i)    paying a dividend on its Capital Stock at any time within 60
     days after the declaration thereof if, on the declaration date, the Company
     could have paid such dividend in compliance with the preceding paragraph of

     Restricted Subsidiary of the Company, in exchange for, or out of the
     proceeds of the substantially concurrent sale of Qualified Stock of the
     Company;

          (iii)  retiring any Indebtedness of the Company subordinated in right
     of payment to the Notes in exchange for, or out of the proceeds of, the
     substantially concurrent incurrence of Indebtedness of the Company (other
     than Indebtedness to a Subsidiary of the Company), provided that such new
     Indebtedness (A) is subordinated in right of payment to the Notes at least
     to the same extent as, (B) has an Average Life at least as long as, and (C)
     has no scheduled principal payments due in any amount earlier than, any
     equivalent amount of principal under the Indebtedness so retired;

     Company in exchange for, or out of the proceeds of, the substantially
     concurrent incurrence of Indebtedness of the Company or any Restricted
     Subsidiary that is permitted under

     Section 4.10 hereof (in the case of Indebtedness of Restricted
     Subsidiaries) and that (A) is not secured by any assets of the Company or
     any Restricted Subsidiary to a greater extent than the retired Indebtedness
     was so secured, (B) has an Average Life at least as long as the retired
     Indebtedness, and (C) is subordinated in right of payment to the Notes at
     least to the same extent as the retired Indebtedness;

     Capital Stock shall not exceed, in the aggregate, the sum of $2 million
     plus the aggregate cash proceeds received by the Company subsequent to the
     Issue Date from issuances of Capital Stock or options to acquire Capital
     Stock by the Company to directors, officers or employees of the Company and
     its Subsidiaries;

          (vi)   making payments or distributions to dissenting stockholders
     pursuant to applicable law in connection with a consolidation, merger or

permitted pursuant to clauses (x), (y) and (z) of clause (iii) of Section
4.11(a) hereof or clause (ii) of Section 4.11(b) hereof or this clause (viii),
plus (C) the net reduction in Investments made pursuant to this clause (viii)
resulting from distributions on or repayments of such Investments or from the
Net Cash Proceeds from the sale of any such Investment (except in each case to
the extent any such payment or proceeds are included in the calculation of
Consolidated Net Income) or from such Person becoming a Restricted Subsidiary
(valued in each case as provided in the definition of "Investment" set forth in
Section 1.01 hereof), provided that the net reduction in any Investment shall
not exceed the amount of such Investment; and

                                      68

     Restricted Subsidiary and any other Person; provided, in any case, that
     such transaction is on terms that are no less favorable, taken as a whole,

     have been obtained in a comparable transaction by the Company or such
     Restricted Subsidiary with Persons who are not Affiliates of the Company or
     the relevant Restricted Subsidiary (or, in the event that there are no
     comparable transactions involving Persons who are not Affiliates of the

Indebtedness to the Company or a Wholly-Owned Restricted Subsidiary), and (i)
such Subsidiary has total assets of $1,000 or less, (ii) such Subsidiary has
assets of more than $1,000 and an Investment in such Subsidiary in an amount
equal to the Fair Market Value of such Subsidiary would then be permitted under

such Person becoming a Subsidiary. Unless so designated as an Unrestricted
Subsidiary, any Person that becomes a Subsidiary of the Company or any of its
Restricted Subsidiaries shall be classified as a Restricted Subsidiary thereof.

     (b)  The Company shall not, and shall not permit any of its Restricted

transactions that would result in a Person (other than a newly formed Subsidiary
having no outstanding Indebtedness (other than Indebtedness to the Company or a
Restricted Subsidiary) at the date of determination) becoming a Restricted
Subsidiary (whether through an acquisition, the redesignation of an Unrestricted
Subsidiary or otherwise), unless, after giving effect to such action,
transaction or series of transactions on a pro forma basis, (i) the Company
could incur at least $1 of additional Indebtedness pursuant to Section 4.09(a)
hereof and (ii) no Default or Event of Default would occur.

be effective as of the date specified in such Board Resolution, which shall not
be prior to the date such Board Resolution is delivered to the Trustee.

     SECTION IV.18.  Reports.  For as long as any Notes remain outstanding, the
                     -------                                                   
Company shall furnish to the Holders of the Notes and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.  The Company
shall file with the Trustee within 15 days after it files them with the
Commission copies of the annual and quarterly reports and the information,
documents, and other reports that the Company is required to file with the
Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC
Reports").  In the event the Company shall cease to be required to file SEC
Reports pursuant to the Exchange Act, the Company shall nevertheless continue to
file such reports with the Commission (unless the Commission shall not accept
such a filing) and in any event with the Trustee.  The Company shall furnish
copies of the SEC Reports to the Holders of Notes at the time the Company is
required to file the same with the Trustee and will make such information
available to investors who request it in writing.

of Default specified in Section 6.01(g) or Section 6.01(h) hereof) occurs and is
continuing, then and in every such case, the Trustee by a notice in writing to
the Company may, and at the direction of the Holders of not less than 25 percent
of the outstanding aggregate principal amount of Notes by a notice in writing to
the Company and the Trustee, shall declare the Default Amount and any accrued
and unpaid interest on all Notes then outstanding to be immediately due and
payable.  Upon any such declaration, such Default Amount and any accrued and
unpaid interest on all Notes then outstanding will become and be immediately due
and payable.

     If an Event of Default specified in Section 6.01(g) or Section 6.01(h)
hereof occurs, the Default Amount and any accrued and unpaid interest on all
Notes then outstanding shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of Notes.

     In the event of a declaration of acceleration because an Event of Default
set forth in Section 6.01(e) hereof 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 Section 6.01(e)
hereof shall be remedied, or cured, or waived by the holders of the relevant
Indebtedness, within 60 calendar days after such event of default; provided no
judgment or decree for the payment of the money due on the Notes has been
obtained by the Trustee as hereinafter in this Article VI provided.

     At any time after a declaration of acceleration with respect to Notes has
been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article VI provided, the Holders
of a majority in principal amount of the outstanding Notes, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if,

          (a)  the Company has paid or deposited with the Trustee a sum
     sufficient to pay:

          (i)  all overdue installments of interest on all Notes,

                                      80
<PAGE>
 
          (ii)   the principal of (and premium, if any, on) any Notes which have
     become due otherwise than by such declaration of acceleration and interest
     thereon at the rate or rates prescribed therefor in such Notes,

          (iii)  to the extent that payment of such interest is lawful, interest
     on the Defaulted Interest at the rate prescribed therefor in the Notes and
     this Indenture, and

          (iv)   all moneys paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel and all other amounts due to the Trustee
     pursuant to Section 7.07 hereof; and

          (b)     all Events of Default with respect to the Notes, other than
     the non-payment of the principal of Notes which have become due solely by
     such declaration of acceleration, have been cured or waived by the Holders
     as provided herein.

     No such rescission shall affect any subsequent Default or impair any right
consequent thereon.

     SECTION VI.3.  Other Remedies.  The Company covenants that if an Event of
                    --------------                                            
Default specified in Section 6.01(a) or Section 6.01(b) hereof occurs the
Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit
of the Holders, the whole amount then due and payable on the Notes for principal
(and premium, if any) and interest and, to the extent that payment of such
interest shall be legally enforceable, interest upon the overdue principal (and
premium, if any) and upon Defaulted Interest, at the rate or rates prescribed
therefor in such Notes; and, in addition thereto, such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and all other amounts due to the Trustee pursuant to
Section 7.07 hereof.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may and, at the
direction of the Holders of not less than a majority of the outstanding
aggregate principal amount of the Notes, shall institute a judicial proceeding
for the collection of the sums so due and unpaid, and may prosecute such
proceeding to judgment or final decree, and may enforce the same against the
Company or any other obligor upon such Notes and collect the moneys adjudged or
decreed to be payable in the manner provided by law out of the Property and
assets of the Company or any other obligor upon such Notes, wherever situated.

     If an Event of Default with respect to the Notes occurs and is continuing,
the Trustee may in its discretion proceed to protect and enforce its rights and
the rights of the Holders by 

                                      81
<PAGE>
 
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

     SECTION VI.4.  Waiver of Past Defaults.  The Holders of not less than a
                    -----------------------                                 
majority in principal amount of the outstanding Notes may, on behalf of the
Holders of all the Notes, waive any past Default and its consequences under this
Article VI, except a Default (a) in the payment of the principal of (or
premium, if any) or interest on, any Note, or (b) in respect of a covenant or
provision hereof which under Section 9.02 hereof cannot be modified or amended
without the consent of the Holders of each outstanding Note affected.

                    -------------------                                 
majority in principal amount of the outstanding Notes shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee; provided that

          (a)  such direction shall not be in conflict with any rule of law or
     with this Indenture or unduly prejudicial to the rights of other Holders
     and would not subject the Trustee to personal liability, and

          (b)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction.

     SECTION VI.6.  Limitation on Suits.  No Holder of Notes shall have any
                    -------------------                                    
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

          (a)  such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Notes;

          (b)  the Holders of not less than 25 percent in principal amount of
     the outstanding Notes shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

          (c)  such Holder or Holders have offered and, if requested, provided
     to the Trustee security or indemnity satisfactory to the Trustee in its
     reasonable discretion against the costs, expenses and liabilities to be
     incurred in compliance with such request;

          (d)  the Trustee for 30 calendar days after its receipt of such
     notice, request and offer of indemnity has failed to institute any such
     proceeding; and

                                      82
<PAGE>
 
          (e)  no direction inconsistent with such written request has been
     given to the Trustee during such 30-day period by the Holders of a majority
     in principal amount of the outstanding Notes;

in any event, it being understood and intended that no one or more Holders of
Notes shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders of Notes, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all Holders of Notes.

     SECTION VI.7.  Rights of Holders to Receive Payment.  Notwithstanding any
                    ------------------------------------                      
other provision of this Indenture, the right of any Holder to receive payment of
principal of (premium, if any) and interest on the Notes held by such Holder, on
or after the respective due dates expressed in the Notes or the redemption dates
or purchase dates provided for therein, or to bring suit for the enforcement of
any such payment on or after such respective dates, shall be absolute and
unconditional and shall not be impaired or affected without the consent of such

voluntary or involuntary case under United States bankruptcy laws, as now or
hereafter constituted, relative to the Company or any other obligor upon the
Notes or the Property and assets of the Company or of such other obligor or
their creditors, the Trustee (irrespective of whether the principal of such
Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled

          THIRD:   To the Company.

the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10 percent in principal amount of

                    --------------------------------                      
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

     SECTION 6.12.  Trustee May Enforce Claims Without Possession of the Notes.
                    ----------------------------------------------------------  
All rights of action and claims under this Indenture or the Notes may be
prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name, as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Notes.

                    ----------------------------------                        
Holder of Notes has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case the Company, the Trustee and the Holders shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

     SECTION 6.14.  Rights and Remedies Cumulative.  Except as otherwise
                    ------------------------------                      
provided in Section 2.09 hereof, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

     SECTION 6.15.  Delay or Omission Not Waiver.  No delay or omission of the

Trustee or of any Holder of any Note to exercise any right or remedy accruing
upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.  Every right and
remedy given by this Article VI or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

funds or adequate indemnity against such risk of liability is not reasonably
assured to it.

accordance with Section 10.02 hereof from the Company or any Holder of Notes.

     (c)  Holders may communicate as provided in Section 312(b) of the Trust
Indenture Act with other Holders with respect to their rights under this
Indenture or under the Notes.

     (d)  Each Holder of Notes, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee shall be
held accountable by reason of the disclosure of any such information as to the
names and addresses of the Holders in accordance with this Section 7.06,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under this Section 7.06.

     (e)  Within 60 calendar days after April 15 of each year commencing with
the year 1999, the Trustee shall transmit by mail to all Holders of Notes, a
brief report dated as of such April 15 if and to the extent required under
Section 313(a) of the Trust Indenture Act.

principal of, premium, if any, and interest on, particular Notes.

     The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation or removal of the Trustee and discharge of this
Indenture.  Subject to any other rights available to the Trustee under
applicable bankruptcy law, when the Trustee incurs expenses after the occurrence

the Trustee and no appointment of a successor Trustee pursuant to this Article
VII shall become effective until the acceptance of appointment by the successor
Trustee under this Section 7.08.

     (b)  The Trustee may resign at any time by giving written notice thereof to
the Company.  If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 calendar days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the outstanding Notes, delivered to the Trustee
and to the Company.

     (d)  If at any time:

          (i)  the Trustee shall fail to comply with Section 310(b) of the Trust
     Indenture Act after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Note for at least six months,
     unless the Trustee's duty to resign is stayed in accordance with the
     provisions of Section 310(b) of the Trust Indenture Act; or

                                      90
<PAGE>
 
          (ii)  the Trustee shall cease to be eligible under Section 7.10 hereof
     and shall fail to resign after written request therefor by the Company or
     by any such Holder; or

          (iii) the Trustee shall become incapable of acting or a decree or

     been entered in respect of the Trustee in an involuntary case under the
     United States bankruptcy laws, as now or hereafter constituted, or any
     other applicable Federal or state bankruptcy, insolvency or similar law; or
     a decree or order by a court having jurisdiction in the premises shall have
     been entered for the appointment of a receiver, custodian, liquidator,
     assignee, trustee, sequestrator (or other similar official) of the Trustee
     or of its Property and assets or affairs, or any public officer shall take
     charge or control of the Trustee or of its Property and assets or affairs
     for the purpose of rehabilitation, conservation, winding up or liquidation;
     or

          (iv)  the Trustee shall commence a voluntary case under the United
     States bankruptcy laws, as now or hereafter constituted, or any other
     applicable Federal or state bankruptcy, insolvency or similar law or shall
     consent to the appointment of or taking possession by a receiver,
     custodian, liquidator, assignee, trustee, sequestrator (or other similar
     official) of the Trustee or its Property and assets or affairs, or shall
     make an assignment for the benefit of creditors, or shall admit in writing
     its inability to pay its debts generally as they become due, or shall take
     corporate action in furtherance of any such action,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to the Notes, or (ii) subject to Section 6.10 hereof, any
Holder who has been a bona fide Holder of a Note for at least six months may, on
behalf of such Holder and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee for the Notes.

     (e)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by or pursuant to a Board Resolution, shall promptly appoint a successor
Trustee.  If, within one year after such resignation, removal or incapability,
or the occurrence of such vacancy, a successor Trustee shall be appointed by the
Holders of a majority in principal amount of the outstanding Notes delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with this
Section 7.08, become the successor Trustee and to that extent replace any
successor Trustee appointed by the Company.  If no successor Trustee shall have
been so appointed by the Company or the Holders and shall have accepted
appointment in the manner hereinafter provided, any Holder that has been a bona
fide Holder of a Note for at least six months may, subject to Section 6.10

                                      91
<PAGE>
 
hereof, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

     (f)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee by mailing written
notice of such resignation, removal and appointment by first class mail, postage
prepaid, to the Holders as their names and addresses appear in the Note
Register.  Each notice shall include the name of the successor Trustee with
respect to the Notes and the address of its Corporate Trust Office.

     (g)  In the event of an appointment hereunder of a successor Trustee, each
such successor Trustee so appointed shall execute, acknowledge and deliver to
the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all Property and money held by such former
Trustee hereunder, subject to its Lien, if any, provided for in Section 7.07
hereof.

     (h)  Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
Section 7.08(g) hereof.

     (i)  No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article VII and under the Trust Indenture Act.

                     ---------------------------                             
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder; provided that such corporation shall be
otherwise qualified and eligible under this Article VII and under the Trust
Indenture Act, without the execution or filing of any paper or any further act
on the part of any of the parties hereto.  In case any Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Notes so authenticated with the same effect
as if such successor Trustee had itself authenticated such Notes.  In the event
that any Notes shall not have been authenticated by such predecessor Trustee,
any such successor Trustee may authenticate and deliver such Notes, in either
its own name or that of its predecessor Trustee,

of authentication of the Trustee.

in either case having a combined capital and surplus of at least $25,000,000.

     If such Person publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining

surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.
Neither the Company nor any Affiliate of the Company shall serve as Trustee
hereunder.  If at any time the Trustee shall cease to be eligible to serve as

resign immediately in the manner and with the effect specified in this Article
VII.

     If the Trustee has or shall acquire any "conflicting interest" within the

                                  DEFEASANCE

     SECTION VIII.1.   Company's Option to Effect Legal Defeasance or Covenant
                       -------------------------------------------------------
Defeasance.  The Company may elect, at its option, at any time, to have Section
- ----------                                                                     
8.02 or Section 8.03 hereof applied to the outstanding Notes (in whole and not
in part) upon compliance with the conditions set forth below in this Article
VIII.  Such election shall be evidenced by a Board Resolution delivered to the
Trustee.

     SECTION VIII.2.   Legal Defeasance and Discharge.  Upon the Company's
                       ------------------------------                     
exercise of its option to have this Section 8.02 applied to the outstanding
Notes (in whole and not in part), the Company shall be deemed to have been
discharged from its obligations with respect to such Notes as provided in this
Section 8.02 on and after the date the conditions set forth in Section 8.04
hereof are satisfied (hereinafter called "Defeasance").  For this purpose, such
Defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Notes and to have satisfied all its
other obligations under such Notes and this Indenture insofar as such Notes are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall
survive until otherwise terminated or discharged hereunder:

     (a)  the rights of Holders of such Notes to receive, solely from the trust
fund described in Section 8.04 hereof and as more fully set forth in such
Section 8.04, payments in respect of the principal of and any premium and
interest on such Notes when such payments are due,

     (b)  the Company's obligations with respect to such Notes under Sections
2.09, 2.10, 2.12, 4.02 and 4.03 hereof,

     (c)  the rights, powers, trusts, duties and immunities of the Trustee under
this Indenture,

     (e)  this Article VIII.

     Subject to compliance with this Article VIII, the Company may exercise its
option to have this Section 8.02 applied to the outstanding Notes (in whole and
not in part) notwithstanding the prior exercise of its option to have Section
8.03 hereof applied to such Notes.

     SECTION VIII.3.  Covenant Defeasance.  Upon the Company's exercise of its
                      -------------------                                     
option to have this Section 8.03 applied to the outstanding Notes (in whole and
not in part), (i) the Company shall be released from its obligations under
Section 5.01(c) and (d), Sections 4.05 through 4.18, inclusive, and any covenant
added to this Indenture subsequent to the Issue Date pursuant to Section 9.01
hereof, (ii) the occurrence of any event specified in Section 6.01(c) or Section
6.01(d) hereof, with respect to any of Section 5.01(c) and (d), Sections 4.05
through 4.18, inclusive, and any covenant added to this Indenture subsequent to
the Issue Date pursuant to Section 9.01 hereof, shall be deemed not to be or
result in an Event of Default, in each case with respect to such Notes as
provided in this Section 8.03 on and after the date the conditions set forth in
Section 8.04 hereof are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Sections 6.01(c) and 6.01(d)
hereof), whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or by reason of any reference in any such Section to
any other provision herein or in any other document; but the remainder of this
Indenture and such Notes shall be unaffected thereby.

     SECTION VIII.4.  Conditions to Defeasance or Covenant Defeasance.  The
                      -----------------------------------------------      
following shall be the conditions to the application of Section 8.02 or Section
8.03 hereof to the outstanding Notes:

with the Trustee as trust funds in trust for the purpose of making the following
payments, specifically pledged as security for, and dedicated solely to the
benefits of the Holders of such Notes, (i) money in an amount, or (ii) U.S.
Government Obligations which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(iii) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any installment of interest on such
Notes on the respective Stated Maturities thereof, in accordance with the terms
of this Indenture and such Notes.

     (b)  In the event of an election to have Section 8.02 hereof apply to the
outstanding Notes, the Company shall have delivered to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee stating that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date of this Indenture, there has been a change in the
applicable Federal income tax law, in either case (i) or (ii) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Notes will not recognize gain or loss for Federal income tax purposes as a
result of the deposit,

                                      95
<PAGE>
 
Defeasance and discharge to be effected with respect to such Notes and will be
subject to Federal income tax on the same amount, in the same manner and at the
same times as would be the case if such deposit, Defeasance and discharge were
not to occur.

     (c)  In the event of an election to have Section 8.03 hereof apply to the
outstanding Notes, the Company shall have delivered to the Trustee an Opinion of
Counsel reasonably acceptable to the Trustee to the effect that the Holders of
such Notes will not recognize gain or loss for Federal income tax purposes as a
result of the deposit and Covenant Defeasance to be effected with respect to
such Notes and will be subject to Federal income tax on the same amount, in the
same manner and at the same times as would be the case if such deposit and
Covenant Defeasance were not to occur.

     (d)  No Default or Event of Default with respect to the outstanding Notes
shall have occurred and be continuing at the time of such deposit after giving
effect thereto or at any time on or prior to the 91st calendar day after the
date of such deposit (it being understood that this condition shall not be
deemed satisfied until after such 91st calendar day).

     (e)  Such Defeasance or Covenant Defeasance shall not cause the Trustee to
have a conflicting interest within the meaning of the Trust Indenture Act
(assuming for the purpose of this clause (e) that all Notes are in default
within the meaning of such Act).

     (f)  Such Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which it is bound.

     (g)  Such Defeasance or Covenant Defeasance shall not result in the trust
arising from such deposit constituting an investment company within the meaning
of the Investment Company Act of 1940, as amended, unless such trust shall be
registered under such Act or exempt from registration thereunder.

     (h)  The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent with respect to such Defeasance or Covenant Defeasance have been
complied with.

     SECTION VIII.5.  Deposited Money and U.S. Government Obligations to be Held
                      ----------------------------------------------------------
in Trust; Miscellaneous Provisions.  All money and U.S. Government Obligations
- ----------------------------------                                            
(including the proceeds thereof) deposited with the Trustee pursuant to Section
8.04 hereof in respect of the outstanding Notes shall be held in trust and
applied by the Trustee, in accordance with the provisions of such Notes and this
Indenture, to the payment, either directly or through any such Paying Agent as
the Trustee may determine, to the Holders of such Notes, of all sums due and to
become due thereon in respect of principal and any premium and interest, but
money so held in trust need not be segregated from other funds except to the
extent required by

                                      96
<PAGE>
 
law. The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 8.04 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of outstanding Notes.

     Anything in this Article VIII to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Order any
money or U.S. Government Obligations held by it as provided in Section 8.04
hereof which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof that would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to the outstanding Notes.

     The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal, premium, if any, or
interest that remains unclaimed for two years; provided that the Trustee or such
                                               --------                         
Paying Agent before being required to make any payment may cause to be published
at the expense of the Company once in a newspaper of general circulation in the
City of New York or mail to each Holder entitled to such money at such Holder's
address (as set forth in the Note Register) notice that such money remains
unclaimed and that after a date specified therein (which shall be at least 30
days from the date of such publication or mailing) any unclaimed balance of such
money then remaining will be repaid to the Company. After payment to the
Company, Holders entitled to such money must look to the Company for payment as
general creditors unless an applicable law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

     SECTION VIII.6.  Reinstatement.  If the Trustee or Paying Agent is unable
                      -------------                                           
to apply any money in accordance with this Article VIII with respect to any
Notes by reason of any order or judgement of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application then the
obligations under this Indenture and such Notes from which the Company has been
discharged or released pursuant to Sections 8.02 or 8.03 hereof shall be revived
and reinstated as though no deposit had occurred pursuant to this Article VIII
with respect to such Notes, until such time as the Trustee or Paying Agent is
permitted to apply all money held in trust pursuant to Section 8.05 hereof with
respect to such Notes in accordance with this Article VIII; provided that if the
Company makes any payment of principal of or any premium or interest on any such
Note following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Notes to receive such
payment from the money so held in trust.

may, at any time, and from time to time, without notice to or consent of any
Holder of Notes, enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

     Holders of all of the Notes, or to surrender any right or power herein
     conferred upon the Company; or

          (c)  to add any additional Events of Default; or

     provision hereof which may be inconsistent with any other provision hereof
     or to add any other provisions with respect to matters or questions arising
     under this Indenture; provided that such actions shall not adversely affect
                           --------

                    -----------------------                                     
not less than a majority in principal amount of the outstanding Notes, by Act of
said Holders delivered to the Company and the Trustee, the Company and the
Trustee may enter into one or more indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any manner the rights of
the Holders; provided that no such supplemental indenture shall, without the
consent of the Holder of each outstanding Note,

<PAGE>
 
          (a)  change the Stated Maturity of the principal of, or any
     installment of interest on, any Note, or alter the redemption provisions
     thereof, or reduce the principal amount thereof (or any premium, if any),
     or the interest thereon, that would be due and payable upon Maturity
     thereof, or change the place of payment where, or the coin or currency in
     which, any Note or any premium or interest thereon is payable, or impair
     the right to institute suit for the enforcement of any such payment on or
     after the Maturity thereof; or

          (b)  reduce the percentage in principal amount of the outstanding
     Notes, the consent of whose Holders is required for any such supplemental
     indenture; or

          (c)  modify any of the provisions of Section 6.04 hereof, except to

          (d)  subordinate in right of payment, or otherwise subordinate, the
     Notes to any other Indebtedness; or

          (e)  modify any of the provisions of this Section 9.02, except to
     increase any percentage set forth herein or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each outstanding Note affected thereby.

     It shall not be necessary for any Act of Holders under this Section 9.02 to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

     SECTION IX.3.  Effect of Supplemental Indentures.  Upon the execution of
                    ---------------------------------                        
any supplemental indenture under this Article IX, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Notes theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby.

     SECTION IX.4.  Compliance with Trust Indenture Act.  Every amendment or
                    -----------------------------------                     
supplement to this Indenture or the Notes shall comply with the Trust Indenture
Act as then in effect.

     SECTION IX.5.  Revocation and Effect of Consents and Waivers.  A consent to
                    ---------------------------------------------               
an amendment, supplement or a waiver by a Holder of a Note shall bind the Holder
and every subsequent Holder of such Note or portion of such Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
or waiver is not made on such Note; 

                                      99
<PAGE>
 
provided that any such Holder or subsequent Holder may revoke the consent or 
- --------                                   
waiver as to such Holder's Note or portion of such Note if the Trustee receives
the notice of revocation at least one day prior to the date the amendment,
supplement or waiver becomes effective. After an amendment, supplement or waiver
becomes effective pursuant to this Article IX, it shall bind every Holder.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to give their consent or take any
other action described above or required or permitted to be taken pursuant to
this Indenture. If a record date is fixed, then notwithstanding the immediately
preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such
action, whether or not such Persons continue to be Holders after such record
date. No such consent shall be valid or effective for more than 120 calendar
days after such record date.

     SECTION IX.6.  Notation on or Exchange of Notes.  If a supplemental
                    --------------------------------                    
indenture changes the terms of a Note, the Trustee may require the Holder
thereof to deliver such Note to the Trustee. The Trustee may place an
appropriate notation on such Note regarding the changed terms and return it to
the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for such Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Note shall not affect the validity of such amendment
or supplement.

     SECTION IX.7.  Trustee to Execute Supplemental Indentures.  The Trustee
                    ------------------------------------------              
shall execute any supplemental indenture authorized pursuant to this Article IX
if such supplemental indenture does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may, but shall
not be required to, execute such supplemental indenture. In executing any
supplemental indenture, the Trustee shall be (subject to Section 7.01 hereof)
fully protected in relying upon an Officers' Certificate and an Opinion of
Counsel, which shall not be at the expense of the Trustee, stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.

                   ----------------------------                                
provision of this Indenture limits, qualifies or conflicts with the duties
imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of, Sections

                                      100
<PAGE>
 
310 to 318, inclusive, of the Trust Indenture Act, such imposed duties or
incorporated provision shall control.

     SECTION X.2.  Notices.  Any notice or communication shall be in writing and
                   -------

additional or different addresses for subsequent notices or communications. Any
notice or communication mailed to a Holder shall be sent to the Holder by first
class mail, postage prepaid, at the Holder's address as it appears in the Note
Register and shall be duly given if so sent within the time prescribed. Failure
to mail a notice or communication to a Holder or any defect in it shall not
affect its sufficiency with respect to other Holders. If a notice or
communication is mailed to the Company, the Trustee or a Holder in the manner
provided above, it is duly given, whether or not the addressee receives it. In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give notice by mail to Holders, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

     SECTION X.3.  Certificate and Opinion as to Conditions Precedent.  Upon any

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

- ------------------------------------
below, the Company shall prepare and, not later than 60 days following the
Closing Date, shall file with the Commission the Exchange Offer Registration
Statement with respect to the Registered Exchange Offer. The Company shall use
its best efforts to cause the Exchange Offer Registration Statement to become
effective under the Act within 150 days of the Closing Date.

          (b)    Upon the effectiveness of the Exchange Offer Registration
Statement, the Company shall promptly commence the Registered Exchange Offer, it
being the objective of such Registered Exchange Offer to enable each Holder
electing to exchange Securities for New Securities (assuming that such Holder is
not an affiliate of the Company within the meaning of the Act, acquires the New
Securities in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the New
Securities) to trade such New Securities from and after their receipt without
any limitations or restrictions under the Act and without material restrictions

the United States.

          (c)    In connection with the Registered Exchange Offer, the Company
shall:

          (i)    mail to each Holder a copy of the Prospectus forming part of
     the Exchange Offer Registration Statement, together with an appropriate
     letter of transmittal and related documents;

          (ii)   keep the Registered Exchange Offer open for not less than 30
     days and not more than 45 days after the date notice thereof is mailed to
     the Holders (or longer if required by applicable law);

          (iii)  utilize the services of a depositary for the Registered
     Exchange Offer with an address in the Borough of Manhattan, The City of New
     York; and

          (d)    As soon as practicable after the close of the
Registered Exchange Offer, the Company shall:

          (i)    accept for exchange all Securities tendered and not validly
     withdrawn pursuant to the Registered Exchange Offer;

          (ii)   deliver to the Trustee for cancellation all securities so
     accepted for exchange; and

          (iii)  cause the Trustee or the New Securities Trustee, as the case
     may be, promptly to authenticate and deliver to each Holder of Securities
     New Securities equal in principal amount to the Securities of such Holder
     so accepted for exchange.

          (e)    The Purchasers and the Company acknowledge that, pursuant to
interpretations by the Commission's staff of Section 5 of the Act, and in the
absence of an applicable exemption therefrom, each Exchanging Dealer is required
to deliver a Prospectus in connection with a sale of any New Securities received
by such Exchanging Dealer pursuant to the Registered Exchange Offer in exchange
for Securities acquired for its own account as a result of market-making
activities or other trading activities.  Accordingly, the Company shall:

          (i)    include the information set forth in Annex A hereto on the
     cover of the Exchange Offer Registration Statement, in Annex B hereto in
     the forepart of the Exchange Offer Registration Statement in a section
     setting forth details of the Exchange Offer, and in Annex C hereto in the
     underwriting or plan of distribution section of the Prospectus forming a
     part of the Exchange Offer Registration Statement, and include the
     information set forth in Annex D hereto in the Letter of Transmittal
     delivered pursuant to the Registered Exchange Offer; and

          (ii)   use its best efforts to keep the Exchange Offer Registration
     Statement continuously effective under the Act during the Exchange Offer
     Registration Period for delivery by Exchanging Dealers in connection with
     sales of New Securities received pursuant to the Registered Exchange Offer,
     as contemplated by Section 4(h) below.

          (f)  In the event that any Purchaser determines that it is not
eligible to participate in the Registered Exchange Offer with respect to the
exchange of Securities constituting any portion of an unsold allotment, at the
request of such Purchaser, the Company shall issue and deliver to such Purchaser
or the party purchasing New Securities registered under a Shelf Registration
Statement as contemplated by Section 3 hereof from such Purchaser, in exchange
for such Securities, a like principal amount of New Securities. The Company
shall seek to cause the CUSIP Service Bureau to issue the same CUSIP number for
such New Securities as for New Securities issued pursuant to the Registered
Exchange Offer.

          3.   Shelf Registration.  If, (i) because of any change in law or
               ------------------                                          
applicable interpretations thereof by the Commission's staff, the Company
determines upon advice of its outside counsel that it is not permitted to effect
the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for
any other reason the Exchange Offer Registration Statement has not been filed
with the Commission within 60 days of the Closing Date, or (iii) for any other
reason the Registered Exchange Offer is not consummated within 180 days of the
Closing Date, or (iv) any Purchaser so requests with respect to Securities held
by it following consummation of the Registered Exchange Offer, or (v) in the
case of any Purchaser that participates in the Registered Exchange Offer or
acquires New Securities pursuant to Section 2(f) hereof, such Purchaser does not
receive freely tradeable New Securities in exchange for Securities constituting
any portion of an unsold allotment (it being understood that, for purposes of
this Section 3, (x) the requirement that a Purchaser deliver a Prospectus
containing the information required by Items 507 and/or 508 of Regulation S-K
under the Act in connection with sales of New Securities acquired in exchange
for such Securities shall result in such New Securities being not "freely
tradeable" but (y) the requirement that an Exchanging Dealer deliver a
Prospectus in connection with sales of New Securities acquired in the Registered
Exchange Offer in exchange for Securities acquired as a result of market-making
activities or other trading activities shall not result in such New Securities
being not "freely tradeable"), the following provisions shall apply:

          (a)  The Company shall as promptly as practicable (but in no event
more than 30 days after so required or requested pursuant to this Section 3),
file with the Commission and thereafter shall use its best efforts to cause to
be declared effective under the Act a Shelf Registration Statement relating to
the offer and sale of the Securities or the New Securities, as applicable, by
the Holders from time to time in accordance with the methods of distribution
elected by such Holders and set forth in such Shelf Registration Statement;
provided, that with respect to New Securities received by a Purchaser in
- --------
exchange for Securities constituting any portion of an unsold allotment, the
Company may, if permitted by current interpretations by the Commission's staff,
file a post-effective amendment to the Exchange Offer Registration Statement
containing the information required by Regulation S-K Items 507 and/or 508, as
applicable, in satisfaction of its obligations under this paragraph (a) with
respect thereto, and any such Exchange Offer Registration Statement, as so
amended, shall be referred to herein as, and governed by the provisions herein
applicable to, a Shelf Registration Statement.

          (b)  The Company shall use its best efforts to keep the Shelf
Registration Statement continuously effective in order to permit the Prospectus
forming part thereof to be usable by Holders for a period of two years from the
date the Shelf Registration Statement is declared effective by the Commission or
such shorter period that will terminate when all the Securities or New
Securities, as applicable, covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement (in any such case, such period
being called the "Shelf Registration Period").  The Company shall be deemed not
to have used its best efforts to keep the Shelf Registration Statement effective
during the requisite period if it voluntarily takes any action that would result
in Holders of securities covered thereby not being able to offer and sell such
securities during that period, unless (i) such action is required by applicable
law, or (ii) such action is taken by the Company in good faith and for valid
business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, so long as the
Company promptly thereafter complies with the requirements of Section 4(k)
hereof, if applicable.

          (c)  No Holder of Securities may include any of its Securities in any
Shelf Registration Statement pursuant to this Agreement unless such Holder
furnishes to the Company in writing, within 10 days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein, and each such Holder agrees to furnish promptly to
the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

     shall use its best efforts to reflect in each such document, when so filed
     with the Commission, such comments as you and your counsel reasonably may
     propose.

          (b)  The Company shall ensure that (i) any Registration Statement and
     any amendment thereto and any Prospectus forming part thereof and any
     amendment or supplement thereto complies in all material respects with the
     Act and the rules and regulations thereunder, (ii) any Registration
     Statement and any amendment thereto does not, when it becomes effective,
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading and (iii) any Prospectus forming part of any
     Registration Statement, and any amendment or supplement to such Prospectus,
     does not include an untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements, in the light of
     the circumstances under which they were made, not misleading.

          (c)  (1)   The Company shall advise you and, in the case of a Shelf

     any such Holder or Exchanging Dealer, confirm such advice in writing:

               (i)   of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

               (ii)  of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the securities
          included therein for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

               (iii) of the happening of any event that requires the making of
          any changes in the Registration Statement or the Prospectus so that,
          as of such date, the statements therein are not misleading and do not
          omit to state a material fact required to be stated therein or

     facilitate the timely preparation and delivery of certificates representing
     Securities to be sold pursuant to any Registration Statement free of any
     restrictive legends and in such denominations and registered in such names

designated by the Majority Holders to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, will reimburse the Purchasers for the reasonable fees and
disbursements of counsel acting in connection therewith. Notwithstanding the
foregoing, the Holders of any Securities or New Securities being registered on
the Shelf Registration Statement shall pay all agency or brokerage fees and
commissions and underwriting discounts and commissions attributable to the sale
of such Securities or New Securities and the fees and disbursements of any
counsel retained by such Holders other that counsel referred to above.

          6.  Indemnification and Contribution.
              -------------------------------- 

          (a) In connection with any Registration Statement, the Company agrees
     to indemnify and hold harmless each Holder of securities covered thereby
     (including each Purchaser and, with respect to any Prospectus delivery as
     contemplated in Section 4(h) hereof, each Exchanging Dealer), the
     directors, officers, employees and agents of each such Holder and each
     person who controls any such Holder within the meaning of either the Act or
     the Exchange Act against any and all losses, claims, damages or
     liabilities, joint or several, to which they or any of them may become
     subject under the Act, the Exchange Act or other Federal or state statutory
     law or regulation, at common law or otherwise, insofar as such losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement as originally filed
     or in any amendment thereof, or in any preliminary Prospectus or
     Prospectus, or in any amendment thereof or supplement thereto, or arise out
     of or are based upon the omission or alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and agrees to reimburse each such
     indemnified party, as incurred, for any legal or other expenses reasonably
     incurred by them in connection with investigating or defending any such
     loss, claim, damage, liability or action; provided, however, that the
                                               --------  -------          
     Company will not be liable in any case to the extent that any such loss,
     claim, damage or liability arises out of or is based upon any such untrue
     statement or alleged untrue 
<PAGE>
 
                                                                              18

     statement or omission or alleged omission made therein in reliance upon and
     in conformity with written information furnished to the Company by or on
     behalf of any such Holder specifically for inclusion therein. This
     indemnity agreement will be in addition to any liability which the Company
     may otherwise have.

          The Company also agrees to indemnify or contribute to Losses of, as
     provided in Section 6(d), any underwriters of Securities registered under a
     Shelf Registration Statement, their officers and directors and each person
     who controls such underwriters on substantially the same basis as that of
     the indemnification of the Purchaser and the selling Holders provided in
     this Section 6(a) and shall, if requested by any Holder, enter into an
     underwriting agreement reflecting such agreement, as provided in Section
     4(q) hereof.

          (b) Each Holder of securities covered by a Registration Statement
     (including each Purchaser and, with respect to any Prospectus delivery as
     contemplated in Section 4(h) hereof, each Exchanging Dealer) severally
     agrees to indemnify and hold harmless (i) the Company, (ii) each of its
     directors, (iii) each of its officers who signs such Registration Statement
     and (iv) each person who controls the Company within the meaning of either
     the Act or the Exchange Act to the same extent as the foregoing indemnity
     from the Company to each such Holder, but only with reference to written
     information relating to such Holder furnished to the Company by or on
     behalf of such Holder specifically for inclusion in the documents referred
     to in the foregoing indemnity.  This indemnity agreement will be in
     addition to any liability which any such Holder may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     6 or notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section 6, notify the indemnifying party in writing of the
     commencement thereof; but the failure so to notify the indemnifying party
     (i) will not relieve it from liability under paragraph (a) or (b) above
     unless and to the extent it did not otherwise learn of such action and such
     failure results in the forfeiture by the indemnifying party of 
<PAGE>
 
                                                                              19

     substantial rights and defenses and (ii) will not, in any event, relieve
     the indemnifying party from any obligations to any indemnified party other
     than the indemnification obligation provided in paragraph (a) or (b) above.
     The indemnifying party shall be entitled to appoint counsel of the
     indemnifying party's choice at the indemnifying party's expense to
     represent the indemnified party in any action for which indemnification is
     sought (in which case the indemnifying party shall not thereafter be
     responsible for the fees and expenses of any separate counsel retained by
     the indemnified party or parties except as set forth below); provided,
                                                                  -------- 
     however, that such counsel shall be satisfactory to the indemnified party.
     -------
     Notwithstanding the indemnifying party's election to appoint counsel to
     represent the indemnified party in an action, the indemnified party shall
     have the right to employ separate counsel (including local counsel), and
     the indemnifying party shall bear the reasonable fees, costs and expenses
     of such separate counsel (and local counsel) if (i) the use of counsel
     chosen by the indemnifying party to represent the indemnified party would
     present such counsel with a conflict of interest, (ii) the actual or
     potential defendants in, or targets of, any such action include both the
     indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that there may be legal defenses available
     to it and/or other indemnified parties which are different from or
     additional to those available to the indemnifying party, (iii) the
     indemnifying party shall not have employed counsel satisfactory to the
     indemnified party to represent the indemnified party within a reasonable
     time after notice of the institution of such action or (iv) the
     indemnifying party shall authorize the indemnified party to employ separate
     counsel at the expense of the indemnifying party. An indemnifying party
     will not, without the prior written consent of the indemnified parties,
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless such settlement, compromise or consent includes an
     unconditional release of each
<PAGE>
 
                                                                              20

     indemnified party from all liability arising out of such claim, action,
     suit or proceeding.

          (d) In the event that the indemnity provided in paragraph (a) or (b)
     of this Section 6 is unavailable to or insufficient to hold harmless an
     indemnified party for any reason, then each applicable indemnifying party,
     in lieu of indemnifying such indemnified party, shall have a joint and
     several obligation to contribute to the aggregate losses, claims, damages
     and liabilities (including legal or other expenses reasonably incurred in
     connection with investigating or defending same) (collectively "Losses") to
     which such indemnified party may be subject in such proportion as is
     appropriate to reflect the relative benefits received by such indemnifying
     party, on the one hand, and such indemnified party, on the other hand, from
     the Initial Placement and the Registration Statement which resulted in such
     Losses; provided, however, that in no case shall any Purchaser or any
             --------  -------                                            
     subsequent Holder of any Security or New Security be responsible, in the
     aggregate, for any amount in excess of the purchase discount or commission
     applicable to such Security, or in the case of a New Security, applicable
     to the Security which was exchangeable into such New Security, as set forth
     on the cover page of the Final Memorandum, nor shall any underwriter be
     responsible for any amount in excess of the underwriting discount or
     commission applicable to the securities purchased by such underwriter under
     the Registration Statement which resulted in such Losses.  If the
     allocation provided by the immediately preceding sentence is unavailable
     for any reason, the indemnifying party and the indemnified party shall
     contribute in such proportion as is appropriate to reflect not only such
     relative benefits but also the relative fault of such indemnifying party,
     on the one hand, and such indemnified party, on the other hand, in
     connection with the statements or omissions which resulted in such Losses
     as well as any other relevant equitable considerations.  Benefits received
     by the Company shall be deemed to be equal to the sum of (x) the total net
     proceeds from the Initial Placement (before deducting expenses) as set
     forth on the cover page of the Final Memorandum and (y) the total amount of
     additional interest which the Company was not required to pay as a result
     of registering the 
<PAGE>
 
                                                                              21

     securities covered by the Registration Statement which resulted in such
     Losses. Benefits received by the Purchasers shall be deemed to be equal to
     the total purchase discounts and commissions as set forth on the cover page
     of the Final Memorandum, and benefits received by any other Holders shall
     be deemed to be equal to the value of receiving Securities or New
     Securities, as applicable, registered under the Act. Benefits received by
     any underwriter shall be deemed to be equal to the total underwriting
     discounts and commissions, as set forth on the cover page of the Prospectus
     forming a part of the Registration Statement which resulted in such Losses.
     Relative fault shall be determined by reference to whether any alleged
     untrue statement or omission relates to information provided by the
     indemnifying party, on the one hand, or by the indemnified party, on the
     other hand. The parties agree that it would not be just and equitable if
     contribution were determined by pro rata allocation or any other method of
     allocation which does not take account of the equitable considerations
     referred to above. Notwithstanding the provisions of this paragraph (d), no
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation. For purposes of
     this Section 6, each person who controls a Holder within the meaning of
     either the Act or the Exchange Act and each director, officer, employee and
     agent of such Holder shall have the same rights to contribution as such
     Holder, and each person who controls the Company within the meaning of
     either the Act or the Exchange Act, each officer of the Company who shall
     have signed the Registration Statement and each director of the Company
     shall have the same rights to contribution as the Company, subject in each
     case to the applicable terms and conditions of this paragraph (d).

          (e)  The provisions of this Section 6 will remain in full force and
     effect, regardless of any investigation made by or on behalf of any Holder
     or the Company or any of the officers,  directors or controlling persons
     referred to in Section 6 hereof, and will survive the sale by a Holder of
     securities covered by a Registration Statement.

underwritten Shelf Registration Statement hereunder unless such Holder (i)
agrees to sell such Holder's Securities on the basis provided in any
underwriting arrangements entered into in connection therewith and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

          8.  Miscellaneous.
              ------------- 

          (a) No Inconsistent Agreements.  The Company has not, as of the date
              --------------------------                                      
     hereof, entered into, nor shall it, on or after the date hereof, enter
     into, any agreement with respect to its securities that is inconsistent
     with the rights granted to the Holders herein or otherwise conflicts with
     the provisions hereof.

          (b) Amendments and Waivers.  The provisions of this Agreement,
              ----------------------                                    
     including the provisions of this sentence, may not be amended, qualified,
     modified or supplemented, and waivers or consents to departures from the
     provisions hereof may not be given, unless the Company has obtained the
     written consent of the Holders of at least a majority of the then
     outstanding aggregate principal amount of Securities (or, after the
     consummation of any Exchange Offer in accordance with Section 2 hereof, of
     Securities and New Securities); provided that, with respect to any matter
                                     --------                                 
     that directly or indirectly affects the rights of any Purchaser hereunder,
     the Company shall obtain the written consent of each such Purchaser against
     which such amendment, qualification, supplement, waiver or consent is to be
     effective.  Notwithstanding the foregoing (except the foregoing proviso), a
     waiver or consent to departure from the provisions hereof with respect to a
     matter that relates exclusively to the rights of Holders whose securities
     are being sold pursuant to a Registration Statement and that does not
     directly or indirectly affect the rights of other Holders may be given by
     the Majority Holders, determined on the basis of securities being sold
     rather than registered under such Registration Statement.

                  [FORM OF OFFERING MEMORANDUM DESCRIPTION OF
                            REGISTRATION AGREEMENT]



                      EXCHANGE OFFER; REGISTRATION RIGHTS

          The Company and the Initial Purchasers will enter into the
Registration Agreement on or prior to the Closing Date.  The Company will agree,
pursuant to the Registration Agreement with the Initial Purchasers, for the
benefit of the holders, that the Company will, at its cost, (i) no later than 60
days after the Closing Date file the Exchange Offer Registration Statement with
the Commission relating to the Registered Exchange Offer to exchange the Notes
for Exchange Notes having terms substantially identical in all material respects
to the Notes (except that the Exchange Notes will not contain terms with respect
to transfer restrictions) and (ii) use its best efforts to cause the Exchange
Offer Registration Statement to be declared effective under the Securities Act
not later than 150 days after the Closing Date.  Upon the effectiveness of the
Exchange Offer Registration Statement, the Company will offer the Exchange Notes
in exchange for surrender of the Notes.  The Company will keep the Registered
Exchange Offer open for not less than 30 days and not more than 45 days (or
longer if required by applicable law) after the date notice of the Registered
Exchange Offer is mailed to the holders.  For each Note surrendered to the
Company pursuant to the Registered Exchange Offer, the holder of such Note will
receive an Exchange Note having a principal amount equal to that of the
surrendered Note.  Interest on each Exchange Note will accrue from the last
Interest Payment Date on which interest was paid on the Note surrendered in
exchange therefor, or, if no interest has been paid on such Note, from the date
of its original issue.  Under existing Commission interpretations, the Exchange
Notes would be freely transferable by holders other than affiliates of the
Company after the Registered Exchange Offer without further registration under
the Securities Act if the holder of the Exchange Notes represents that it is
acquiring the Exchange Notes 
<PAGE>
 
                                                                               2

in the ordinary course of its business, that it has no arrangement or
understanding with any person to participate in the distribution of the Exchange
Notes and that it is not an affiliate of the Company, as such terms are
interpreted by the Commission; provided that broker-dealers ("Participating
Broker-Dealers") receiving Exchange Notes in the Registered Exchange Offer will
have a prospectus delivery requirement with respect to resales of such Exchange
Notes. The Commission has taken the position that Participating Broker-Dealers
may fulfill their prospectus delivery requirements with respect to Exchange
Notes (other than a resale of an unsold allotment from the original sale of the
Notes) with the prospectus contained in the Exchange Offer Registration
Statement. Under the Registration Agreement, the Company is required to allow
Participating Broker-Dealers and other persons, if any, with similar prospectus
delivery requirements to use the prospectus contained in the Exchange Offer
Registration Statement in connection with the resale of such Exchange Notes.

          A holder of Notes (other than certain specified holders) who wishes to
exchange such Notes for Exchange Notes in the Registered Exchange Offer will be
required to represent that any Exchange Notes to be received by it will be
acquired in the ordinary course of its business, and that at the time of the
commencement of the Registered Exchange Offer it has no arrangement or
understanding with any person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Notes and that it is not an
"affiliate" of the Company, as defined in Rule 405 of the Securities Act, or if
it is an affiliate, that it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.

          In the event that applicable interpretations of the staff of the
Commission do not permit the Company to effect such a Registered Exchange Offer,
or if for any other reason the Registered Exchange Offer is not consummated
within 180 days after the Closing Date, or if the Initial Purchasers so request
with respect to Notes not eligible to be exchanged for Exchange Notes in the
Registered Exchange Offer, or if any holder of Notes does not receive freely
tradeable Exchange Notes in the Registered Exchange Offer, the Company will, at
its cost, (a) as promptly as practicable, file a Shelf Registration Statement
<PAGE>
 
                                                                               3

covering resales of the Notes or the Exchange Notes, as the case may be, (b) use
its best efforts to cause the Shelf Registration Statement to be declared
effective under the Securities Act and (c) keep the Shelf Registration Statement
effective until two years after its effective date or such shorter period ending
when all resales of Notes or Exchange Notes covered by such Shelf Registration
Statement have been made.  The Company will, in the event a Shelf Registration
Statement is filed, among other things, provide to each holder for whom such
Shelf Registration Statement was filed copies of the prospectus which is a part
of the Shelf Registration Statement, notify each such holder when the Shelf
Registration Statement has become effective and take certain other actions as
are required to permit unrestricted resales of the Notes or the Exchange Notes,
as the case may be.  A holder selling such Notes or Exchange Notes pursuant to
the Shelf Registration Statement generally would be required to be named as a
selling security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Agreement which are applicable to such holder
(including certain indemnification obligations).

          If (i) within 60 days after the Closing Date, neither the Exchange
Offer Registration Statement nor the Shelf Registration Statement has been filed
with the Commission; (ii) within 150 days after the Closing Date the Exchange
Offer Registration Statement has not been declared effective; (iii) within 180
days after the Closing Date, neither the Registered Exchange Offer has been
consummated nor the Shelf Registration Statement has been declared effective; or
(iv) after either the Exchange Offer Registration Statement or the Shelf
Registration Statement has been declared effective, such Registration Statement
thereafter ceases to be effective or usable (subject to certain exceptions) in
connection with resales of Notes or Exchange Notes in accordance with and during
the periods specified in the Registration Agreement, Special Interest will
accrue and be payable semi-annually on the Notes and the Exchange Notes (in
addition to the stated interest on the Notes and the Exchange Notes) from and
including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured.  Special
Interest will accrue and be payable semi-annually at a rate of

                                                                               4

0.50% per annum during the 90-day period immediately following the occurrence of
any Registration Default and shall increase by 0.25% per annum at the end of
each subsequent 90-day period, but in no event shall such rate exceed 2.00% per
annum in the aggregate regardless of the number of Registration Defaults.

          The summary herein of certain provisions of the Registration Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Registration Agreement, a
copy of which is available upon request to the Company.

Each broker-dealer that receives New Securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Securities.  The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.  This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Securities received in exchange for Securities where such New Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities.  The Company has agreed that, starting on the Expiration
Date (as defined herein) and ending on the close of business on the first
anniversary of the Expiration Date, it will make this Prospectus available to
any broker-dealer for use in connection with any such resale.  See "Plan of
Distribution."

Each broker-dealer that receives New Securities for its own account in exchange
for Securities, where such Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Securities.  See "Plan of Distribution."

                             PLAN OF DISTRIBUTION
                             --------------------

     Each broker-dealer that receives New Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities.  The Company has agreed
that, starting on the Expiration Date and ending on the close of business on the
first anniversary of the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale.

          The Company will not receive any proceeds from any sale of New
Securities by broker-dealers.  New Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the New Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Securities.  Any broker-dealer that resells New Securities that were received by
it for its own account pursuant to the Exchange Offer and any broker or dealer
that participates in a distribution of such New Securities may be deemed to be
an "underwriter" within the meaning of the Securities Act and any profit of any
such resale of New Securities and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act.  The Letter of Transmittal states that by acknowledging that it will
deliver and by delivering a prospectus, a broker-dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
<PAGE>
 
          For a period of 1 year after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

and/or 508.]

     the Equipment or Software supplied by DSC or manufactured by its suppliers
     in accordance with any design or any special instruction furnished by the
     Purchaser, or which is used by the Purchaser in a manner or for a purpose

ARTICLE 2. ORDERING PROCEDURE
           ------------------

This article is hereby replaced in its entirety with the following:

   2.1 Purchaser may purchase or license Equipment, Software, Systems, or
   Installation Services by sending a written order ("Purchase Order") to
   ALCATEL.  The Purchase Order will constitute a firm offer and will identify,
   by quantity, part number and description, the Equipment, Software, System, or
   Installation Services that Purchaser desires to purchase or license, the
   price ("Contract Price" as defined in Article 3) of the ordered items, and
   the requested delivery dates and installation dates, as applicable.  The
   terms and conditions of this Agreement shall control over any conflicting
   terms and conditions stated on any Purchase Order.  All Purchase Orders are
   subject to review and acceptance by ALCATEL.

   2.2 Upon acceptance of a Purchase Order, ALCATEL shall furnish the requested
   Products to Purchaser for delivery on a mutually agreed upon date.

   2.3 Purchaser may, subject to mutual written agreement on the impact on the
   Contract Price and time of performance, make modifications to a Purchase
   Order any time prior to the scheduled shipment date.

   2.4 ALCATEL will provide Purchaser with a reasonable opportunity, upon at
   least three (3) days prior written request by Purchaser, to inspect all
   Equipment purchased and the operation of any Software licensed pursuant to
   this Agreement for conformance with ALCATEL's specifications therefor
   provided such inspection occurs not less than five (5) working days prior to
   shipment.  Neither such opportunity to inspect, nor any inspection made by
   Purchaser prior to shipment, nor any statement or indication by Purchaser
   prior to Purchaser's receipt of such Equipment or Software shall in any way
   be deemed to constitute acceptance of such Equipment or Software by
   Purchaser.  Unless otherwise mutually agreed, in writing, payment for
   Equipment or Software before inspection shall not constitute acceptance
   thereof and is without prejudice to claims Purchaser may have against ALCATEL
   with respect thereto.  Equipment and Software shipped to Purchaser may be
   inspected by Purchaser for conformance to ALCATEL's specifications therefor
   within fifteen (15) days after the date of shipment and shall be deemed
   accepted on the fifteenth (15) day unless Purchaser advises ALCATEL, in
   writing, of the reason for rejection within twenty (20) days after the date
   of shipment.  Any Product rejected by Purchaser shall be repaired or replaced
   in accordance with the WARRANTY provisions of this Agreement.

   ALCATEL reserves the right to subcontract such portions of the (a) Equipment
   manufacture and/or Software development, and/or Installation Services to
   subcontractors of ALCATEL's choice as ALCATEL deems appropriate.  In the
   event Purchaser deems the conduct of any on-site subcontractor to be
   objectionable Purchaser shall so advise ALCATEL and if, after a reasonable
   time, the conduct of the subcontractor has not become acceptable, Purchaser
   may request ALCATEL remove such subcontractor, provided, however, Purchaser
   shall be liable to ALCATEL for any increase in the Contract Price due to an
   increase in the cost or time to perform the work, by a substitute
   subcontractor, which is or would be performed by the subcontractor in
   question.

ARTICLE 8. WARRANTY and ARTICLE 9. WARRANTY ON REPAIRED MATERIALS
           --------                ------------------------------

Both of the aforementioned articles are replaced in their entirety by the

ARTICLE 8. WARRANTY
           --------

   8.1 ALCATEL warrants, for the applicable period stated below, that the
   Equipment and Software media shall, under normal use and service, be free
   from defects in material and faulty workmanship.  ALCATEL further warrants
   that the Equipment and Software shall materially conform to ALCATEL's
   specifications therefor in effect on the date of shipment.  However, ALCATEL
   does not warrant that Software will operate uninterrupted or error free.  The
   initial warranty period ("Initial Warranty Period") for any Product shall be:
   (a) thirteen (13) months from the date of shipment for Product installed by
   ALCATEL or a ALCATEL subcontractor; or (b) twelve (12) months from the date
   of shipment of Product not installed by ALCATEL or a ALCATEL subcontractor.
   Notwithstanding the above described Initial Warranty Period, the Initial
   Warranty Period for ALCATEL's Litespan(R)/Starspan(R) Products

<PAGE>
 
   shall be five (5) years under both options (a) and (b) above in lieu of the
   thirteen (13) and twelve (12) month periods respectively referenced therein.

   8.2 ALCATEL warrants that no later than December 31, 1998, all Product will
   have the following functionality: (a) no value for current date will cause
   any interruption in operation; (b) date-based functionality will behave
   consistently for dates prior to, during, and after the year 2000; (c) in all
   interfaces and data storage, the century in any date will be specified either
   explicitly or by unambiguous algorithms or inferencing rules; and (d) the
   year 2000 will be recognized as a leap year. The forgoing warranty shall
   apply only if Purchaser has implemented ALCATEL's or applicable third party's
   (for whom ALCATEL is the sublicensor) hardware or software patches, updates,
   or enhancements containing modifications to the Product, all provided at no
   charge, to make it meet this warranty.

   8.3 Subject to the provisions of this article, defective Product will be (a)
   returned by Purchaser to ALCATEL's designated facility, at Purchaser's
   expense, (b) repaired or replaced by ALCATEL at no charge to Purchaser, and
   (c) returned to Purchaser's point of shipment at ALCATEL's expense. Purchaser
   shall assume risk of loss or damage to Product returned to ALCATEL for repair
   or replacement until delivery to ALCATEL.  Upon receipt, and until its
   delivery to Purchaser, ALCATEL shall assume the risk of loss or damage to the
   Product being repaired or replaced.  Corrections to Software shall be
   provided electronically or on suitable media chosen by ALCATEL.

   8.4 ALCATEL's sole obligation, and Purchaser's sole remedy, under this
   article is limited to the repair or replacement, at ALCATEL's option, of the
   defective Equipment or correction of erroneous Software.  In the event of a
   warranty claim regarding Equipment, Purchaser shall obtain a Material Return
   Authorization ("MRA") from ALCATEL prior to the return of any defective
   Equipment or part thereof.  Upon receipt of the defective Equipment and the
   MRA or confirmation of a Software error, ALCATEL shall repair or replace the
   returned Equipment or correct the Software unless:  (a) the Product was
   altered, repaired, or reworked by a party other than ALCATEL without
   ALCATEL's prior written consent; or (b) such defects or errors were the
   result of (i) Purchaser's improper storage, mishandling, abuse, or misuse of
   the Product; (ii) Purchaser's use of the Product in conjunction with another
   product which is electronically or mechanically incompatible, or of an
   inferior quality; or (iii) damage by fire, explosion, power failure, or any
   act of nature. ALCATEL shall warrant any Product corrected, repaired, or
   replaced for ninety (90) days from the date of correction or shipment, as
   applicable, or until the end of the Initial Warranty Period, whichever is
   longer.

   8.5 THE FOREGOING WARRANTIES ARE NON-TRANSFERABLE AND ARE PROVIDED IN LIEU
   OF, AND ALCATEL AND ITS SUPPLIERS AND LICENSORS DISCLAIM ALL OTHER
   WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF
   MERCHANTABILITY AND FITNESS FOR INTENDED OR PARTICULAR PURPOSE.

ARTICLE 12. SOFTWARE LICENSE
            ----------------

This Article is hereby amended in its entirety to read as follows:

   12.1  ALCATEL hereby grants Purchaser, and Purchaser hereby accepts, a

   the Software for which activation has been authorized by ALCATEL, solely on a
   single System, or unit of Equipment, as may be applicable.  Use of the
   Software on multiple Systems or with any equipment furnished by a party other

   shall not at any time modify, disassemble, or decompile such Software, or
   transfer or reverse engineer any portion of the Software or functioning of
   any Equipment, or permit others to do so, without ALCATEL's prior written
   consent.  Purchaser agrees it will not attempt to transfer Confidential
   Information, including any Software or System, without the prior written
   consent of ALCATEL.  Purchaser further agrees that it shall not reproduce or
   copy such Software in whole or in part except for backup and archival
   purposes.  Certain network management Software is provided by third parties
   and may be subject to additional license restrictions.

   12.3  In the event of a Purchaser breach regarding Confidential Information,
   ALCATEL reserves the right, upon notice to Purchaser, to (a) require the
   immediate return of all Confidential Information, including all applicable
   Software and copies thereof, wherever

   and all associated documentation for which Purchaser is in breach of license
   rights, or has not paid the applicable fee, and (b) terminate the license for
   such Software and associated documentation granted to Purchaser. Upon receipt
   of such notice, Purchaser agrees to immediately discontinue use and enjoyment
   of such Software and associated documentation.

   12.4  The rights and obligations of Purchaser under Articles 12 and 15 will
   survive expiration or termination of this Agreement for any reason, and shall
   continue even if the Software is no longer used with the Equipment.

Sub-article 23.7 is hereby added to read as follows:

   23.7  Neither party shall disclose the existence of this Agreement (other

   thereof, except with regard to the ownership of intellectual property, will
   be resolved by mutual agreement of the parties.  If such dispute,
   controversy, or claim cannot be settled by mutual agreement of the parties
   such dispute, controversy, or claim will be settled by arbitration in
   accordance with the Rules of Arbitration of the American Arbitration
   Association as in force on the date one party notifies the other, in writing,
   of its right to seek such arbitration.  The arbitration shall be conducted by
   a single arbitrator selected in accordance with the aforementioned rules.

   extraordinary courts or tribunals in the jurisdiction of its choice in order
   to apply for emergency, special or pre-judgment relief with regard to its
   intellectual property rights or rights to receive or make payment hereunder,
   and the parties agree not to contest such jurisdiction.  Judgement upon the
   award rendered by the arbitrator may be entered in any court having
   jurisdiction thereof.

Attachment 1, on a cumulative basis (as measured annually, beginning on the
first anniversary date of the effective date of this Amendment 4) ALCATEL
retains the right to re-negotiate the applicable prices.  In the event that
McLeodUSA exceeds the committed purchases on a cumulative basis (as measured
annually, beginning on the first anniversary date of the effective date of this
Amendment 4) McLeodUSA retains the right to re-negotiate the applicable prices.

McLeodUSA retains the right to verify the industry competitiveness of the
pricing and technology on an annual basis through a Request For Proposal (RFP)
process.  ALCATEL will receive a first right of refusal to match reasonable and
legitimate offers for

           to McLeodUSA Incorporated and Alcatel USA Marketing, Inc.
<PAGE>
 
comparable products and services based on the same criteria used for submittal
and evaluation of third party proposals for the then-subject RFP.

ALCATEL agrees to make commercially reasonable effort to ship generally
available products included on each McLeodUSA purchase order within eight (8)
business weeks (excluding ALCATEL observed holidays) after ALCATEL's acceptance
of each order provided McLeodUSA continuously provides ALCATEL with a monthly
rolling forecast, in printed or electronic format commencing on the date this
Amendment Number 4 becomes effective, of anticipated product purchases.  The
above time frame shall not be applicable to (product) purchase orders for which
ALCATEL has advised McLeodUSA of a longer shipment or lead time requirement.
If, with respect to fifty percent (50%) or more of all orders to which the above
stated time frame applies, ALCATEL has not shipped such orders within ten (10)
weeks after ALCATEL's acceptance of such orders McLeodUSA shall have the right
to re-negotiate the total commitment under this Addendum A.  ALCATEL further
agrees to provide McLeodUSA with product availability intervals (i.e. lead times
order is required before shipment) on an annual basis.

SUPPORT
- -------

ALCATEL agrees to provide a total of five (5) man-years of Operational Engineer
(OE) support during the term of this Agreement with no more than two (2) OE's
committed in the first year and a maximum of three (3) OE's supporting McLeodUSA
simultaneously at any point in time.  These OE's will be located at McLeodUSA
offices and McLeodUSA will provide all necessary office space and facilities for
the OE's.  McLeodUSA may request changes in OE support, by notifying ALCATEL, in
writing, no less than ninety (90) days before any changes in support are to be
effective.  ALCATEL will pay all customary employee expenses associated with
initially locating an OE to the office designated by McLeodUSA however,
McLeodUSA will reimburse ALCATEL for any travel, subsistence, and/or other
reasonable expenses incurred by the OE's when travel is requested or required by
McLeodUSA and any expenses associated with permanently (for this project
assignment) relocating any OE to another McLeodUSA office (which requires a
relocation of the OE's residence) if so requested by McLeodUSA.

TRAINING
- --------

ALCATEL agrees to provide on-site training classes at the rate of one (1) per
quarter in years 1 and 2 of the project, and one (1) class semi-annually in
years 3-6.  During the first two (2) years of the project a class may be
requested at any time during the year (even in advance of accrual) provided,
however, no more than two (2) classes will be taught consecutively at any time.
Training classes will be taught at times mutually agreed between the parties.

SUBCONTRACTORS
- --------------

ALCATEL agrees to provide McLeodUSA with a list of ALCATEL approved installation
subcontractors for Litespan(R) products.

PROVISIONING TEMPLATES
- ----------------------

ALCATEL agrees, once the Litespan(R) product templates are developed for
McLeodUSA, to establish a method of pre-loading, at ALCATEL facilities, required
Litespan(R)/Starspan(R) operating software, software keys, and pre-provisioning
Litespan systems, as applicable, prior to shipment to McLeodUSA. This will be
based on the predefined configuration models, as applicable.

PROBLEM ESCALATION
- ------------------

ALCATEL agrees to provide McLeodUSA with implementation/outage notice and
escalation documentation and procedures for all ALCATEL manufactured systems.

INDUSTRY STANDARDS COMPLIANCE
- -----------------------------

ALCATEL certifies that the RPOTS channel unit will meet the Industry Standard
Carrier Serving Area (CSA) guidelines as specified by industry standards and if,
during the period of Litespan(R) product deployment, the RPOTS channel unit does
not meet the published CSA guidelines, ALCATEL will provide the appropriate
channel unit to meet McLeodUSA service requirements.

ENHANCED COMMUNICATIONS
- -----------------------

The parties agree to work together to establish a mutually acceptable electronic
interface for order processing, trouble reporting, management reporting,
forecasting, and any other procedures which can be electronically linked and
automated, if possible.

BELLCORE LABS INDICES
- ---------------------

Bellcore Labs document TR-418, issue 2, describes a quality and reliability
index in terms of "returned and failed modules" over a given volume of product.
ALCATEL agrees that if, anytime after deployment of a reasonable number of
Litespan(R) products, the rate of "returned and failed modules" for all
Litespan(R) products deployed exceeds the Bellcore Labs applicable quality and
reliability index (per TR-418, issue 2, or the then current Bellcore Labs
standard) McLeodUSA has the right to temporarily or permanently cease further
placement of Litespan(R) Products.  However, McLeodUSA agrees that prior to
taking any such action it will give ALCATEL a reasonable time to rectify any
breach of the above referenced Bellcore Labs index.

   Example:  Assume the Bellcore reliability index states that the "returned and
   failed module" rate per 1000 units deployed is 20, then McLeodUSA could

                                    Page 3

                         PROPRIETARY AND CONFIDENTIAL
           to McLeodUSA Incorporated and Alcatel USA Marketing, Inc.
<PAGE>
 
   require ALCATEL to take remedial action if ALCATEL's "returned and failed
   module" rate equals or exceeds 20.

OVERNIGHT RESPONSE
- ------------------

ALCATEL agrees that if McLeodUSA encounters a shortage of certain Litespan(R)
components in its "Rotating Pool", upon receipt of appropriate purchase order
documentation from McLeodUSA, ALCATEL will use all commercially reasonable
efforts to "overnight" ship such components to McLeodUSA.

LITECRAFT(R) LICENSES
- ---------------------

ALCATEL agrees to provide up to forty (40) licenses, upon McLeodUSA's request,
of the then current applicable version of LITECRAFT(R) software at no additional
charge, thereafter each license of LITECRAFT(R) software shall cost $2,222.00.

EXTENDING THE WARRANTY
- ----------------------

ALCATEL will provide a five (5) year warranty on Litespan(R) products.  The
charge for extending the warranty to seven (7) years is an additional $2.10 per
line for both copper and fiber based collocation models, payable as Litespan(R)
product is ordered by McLeodUSA.  The charge for extending the warranty to seven
(7) years for network build Litespan(R) products will be three percent (3%) of
the purchase price of such products (excluding shipping and taxes).  The
additional charge for extending the warranty is to be included on each McLeodUSA
purchase order.

CTAC SUPPORT
- ------------

ALCATEL will provide Customer Technical Assistance Center (CTAC) support, as
defined in this Agreement, for either the six (6) year deployment period or the
warranty period, whichever is longer, at no additional charge.  Access to CTAC
support by McLeodUSA personnel shall be controlled by authorization code(s) as
mutually agreed by ALCATEL and McLeodUSA.

SEED STOCK
- ----------

McLeodUSA agrees, that by December 31, 1998, it will purchase two (2) fully
functional "100% line-card filled" Litespan(R) HDT's as "seed stock" for
deployment as may be deemed necessary by McLeodUSA, and to establish and
maintain a complete "Rotating Pool" of spare Litespan(R) products.

SOFTWARE MAINTENANCE FEE
- ------------------------

ALCATEL agrees to provide annual updates, releases, and upgrades to maintain the
purchased features of Litespan(R) operating software, LITECRAFT(R) software, and
AMS software for: (i) a prepaid maintenance fee of $3.00 per line as lines are
shipped (1,076,400 X $3.00 for a total of $3,229,200.00 over the ALCATEL
Litespan(R) product deployment

                                    Page 4

plans); or (ii) a one-time lump-sum prepaid software maintenance fee of
$2,700,000.00 (based on Attachment 1), to cover such updates, releases and
upgrades through the year 2003, payable in full no later than October 30, 1998.
The above charges are based on McLeodUSA performing all Litespan(R) product
software upgrades and do not include any required hardware. These prepaid
software maintenance fees do not include any future software features beyond the
proposed GR-303, copper fed Litespan(R), Starspan(R), Integrated P-Phone, VT
UPSR and current features of Litespan(R) operating software as of the effective
date of this Amendment. In the event McLeodUSA elects to enhance Litespan(R)
operating characteristics (for example, Broadband features), ALCATEL agrees to
negotiate, in good faith, pricing for the enhanced features offered at that
time.

LUMP SUM OFFER
- --------------

If McLeodUSA purchases the prepaid, lump-sum software maintenance for
$2,700,000.00 (see Software Maintenance Fee above), and purchases the extended
                   ------------------------                                   
Litespan(R) products warranty for two (2) additional years pursuant to the
paragraph above entitled Extending the Warranty, ALCATEL will provide two (2)
                         ----------------------                              
fully equipped Litespan(R) systems, configured per the defined Collocation Model
configuration, at no charge for use as "seed stock" to support any immediate
demand for ALCATEL Litespan(R) product.  These two (2) "seed stock" systems will
be shipped to a McLeodUSA designated facility upon ALCATEL's receipt of the
software maintenance fee prepayment, in full, and receipt of written
acknowledgment from McLeodUSA of acceptance of the extended warranty offer.

P-PHONE
- -------

ALCATEL agrees, as a future feature, to provide integrated GR-303 capability for
Electronic Business Sets or P-Phone capability for current Litespan(R) products
with trials beginning December 18, 1998.  Until the integrated P-Phone card is
available ALCATEL will provide an interim solution, using other cards, for up to
2000 lines.  This interim solution will be priced at $700.00 per "P-Phone
equivalent" card.  When the P-Phone capability is available, ALCATEL agrees to
provide applicable Litespan(R) operating software and any common equipment
support modules, required to support integrated P-Phone, at no additional
charge.  The integrated P-Phone card will be priced at $700.00 per card.   When
the integrated P-Phone card is available, that card can be substituted for the
interim solution.  If ALCATEL does not meet the P-Phone availability by December
31, 1998, McLeodUSA reserves the right to request an increase in the number of
interim solution lines.  It is understood that if the integrated P-Phone card is
not available by June 30, 1999, McLeodUSA shall have the right to negotiate the
applicable prices.

Product Credit
- --------------

If McLeodUSA acquires Seventeen Million One Hundred Seventy Five Thousand Eight
Hundred Ninety Two Dollars ($17,175,892.00), or more, of the total
Litespan(R)/Starspan(R) product commitment during the first 24 months of the
project plan, ALCATEL will grant McLeodUSA a Litespan(R) product credit of Three
Hundred Sixty-Five Thousand Dollars ($365,000.00) for the FTTC trial products
already delivered to McLeodUSA ATS Division in Cedar Rapids, IA.  If McLeodUSA
fails to achieve the Litespan(R) product purchase

                                    Page 5

                         PROPRIETARY AND CONFIDENTIAL
           to McLeodUSA Incorporated and Alcatel USA Marketing, Inc.
<PAGE>
 
commitment in the first 24 months of the project plan, the amount of Litespan(R)
product credit will be pro-rated to the same level of actual product purchases
(i.e. if 80% of purchase commitment is made, product credit would equal 80% of
the product purchases for the FTTC trial). Any amount payable to ALCATEL from
McLeodUSA would be due on the 25th month after execution of this Amendment.

LAB SYSTEM
- ----------

ALCATEL agrees to provide McLeodUSA a Litespan(R)/Starspan(R) lab system at no
charge consisting of: a COT, 1 RT, and a rack mounted ONU-24, ONU-48, and ONU-
96/LS 200.  As ALCATEL develops new products and enhancements, McLeodUSA may
elect to add these capabilities to the McLeodUSA lab for the purpose of product
evaluation and network integration testing. If any new ALCATEL
Litespan(R)/Starspan(R) enhancement is accepted and deployed in McLeodUSA's
network, the new enhancement will remain in McLeodUSA's lab at no charge, and
any item (i.e. enhancement) which is not accepted and deployed within six (6)
months of delivery will be returned to ALCATEL's designated facility.

REGULATORY CHANGES
- ------------------

ALCATEL understands that McLeodUSA's business plans have been developed under
the Telecommunications Act of 1996 and in the event that said Act's intent is
modified or repealed by a governmental authority with appropriate jurisdiction
to the extent that it substantially prevents McLeodUSA from continuing to
implement the plans contemplated in this Amendment, ALCATEL agrees that should
such regulatory conditions occur, McLeodUSA shall have the option to request re-
negotiation of unit prices based on revised quantities or to re-negotiate unit
prices based on the quantities purchased to date and cease any further purchases
of Litespan(R)/Starspan(R) product.

LINE COST REDUCTION
- -------------------

Line cost reduction can be facilitated via a multi-year discounted prepayment
schedule (see table below) against the purchase price of the total number of ONU
protect optics needed for McLeodUSA's network build plan.  ALCATEL's
calculations, assuming 90% of the anticipated Two Hundred Million Dollar
($200,000,000.00) of product purchased is for network-build applications, of the
total purchase price for protection for the optical path between the HDT and the
remote ONU's or BRXs is valued at Thirty-Five Million Four Hundred Thousand
Dollars ($35,400,000.00) or approximately Forty-Three Dollars ($43.00) per line.
ALCATEL offers McLeodUSA a discount of Five Million Four Hundred Thousand Dollar
($5,400,000.00) which would result in a net price of Thirty Million Dollars
($30,000,000.00), payable as follows:

exceeded.

RPOTS CHANNEL UNIT PRICE DECREASE
- ---------------------------------

An additional discount of Twelve percent (12%) is offered on the RPOTS channel
unit, decreasing the price from $250 to $221 per unit.

NOTE: The package pricing for the Collocation systems at 100% fill remains
unchanged.

CONTINUOUS RPOTS PRICE DECREASES
- --------------------------------

In addition, as long as McLeodUSA meets or exceeds the cumulative purchase
volume shown in Attachment 1 a continuous improvement discount will be offered
on the RPOTS channel unit.  This discount will be cumulative and applicable at
the beginning of each calendar year for new purchases to be made during that
year, as follows:
 
               Cumulative
