                                     PART I

     In this Annual Report on Form 10-K, we will refer to Nucentrix Broadband
Networks, Inc., a Delaware corporation, as "Nucentrix," the "Company," "we,"
"us," and "our."

ITEM 1.  BUSINESS

OVERVIEW

     We provide broadband wireless Internet and wireless subscription television
services using up to approximately 200 MHz of radio spectrum licensed by the FCC
in the 2.1 GHz and 2.5 GHz bands, primarily in medium and small markets across
Texas, Oklahoma and the Midwestern United States. We own the basic trading area
("BTA") authorization, or otherwise license or lease MDS, MMDS and ITFS
spectrum, in 95 markets covering an estimated 9 million total households,
including two markets covering an estimated 400,000 total households for which
we have entered into a definitive agreement or letter of intent to acquire. On
average, we own or lease 151 MHz of spectrum per market. We often refer to our
frequencies collectively in this document as "MMDS."

     The FCC historically had limited the use of MMDS spectrum to one-way analog
transmissions. In September 1998, the FCC announced that it would authorize the
use of MMDS spectrum to provide digital

                                        2
<PAGE>

two-way services, including high-speed Internet, data, voice, and video
services. The FCC finalized its ruling in July 1999 and, in August 2000, opened
an initial, one-week filing window for applications for two-way services. We
filed over 400 applications with the FCC in this initial filing window to
provide digital two-way communications services in 70 of our markets. We have
received FCC licenses for over 95% of these applications, representing 90% of
these markets.

     In September 2001, after proceedings to identify additional spectrum for
third generation ("3G") wireless services that lasted almost one year, the FCC
decided not to relocate incumbent license holders and operators in the 2.5 GHz
band, such as the Company, to other frequency bands. The FCC also added a
flexible use allocation to the 2.5 GHz band, making this band available for
advanced mobile services, including 3G wireless systems. The flexible use
allocation is subject to the protection of existing fixed wireless licenses in
the 2.5 GHz band from interference. See "Business -- Spectrum Allocation
Proceedings for Advanced Wireless Services" of this report.

     Our long-term business strategy is to provide fixed, portable and,
ultimately, mobile broadband Internet access and other information services
using our high-capacity MMDS radio spectrum in medium and small markets. Our
expected range of services includes high-speed Internet connectivity that is
integrated with wireless Local Area Networks for businesses and Home Area
Networks for residential users, to distribute broadband services throughout a
customer's business and home. We currently provide high-speed wireless Internet
access service to over 420 accounts serving an estimated 3,200 end users in
Austin and Sherman-Denison, Texas. These end users primarily are medium-sized
and small businesses, small offices/home offices ("SOHOs") and telecommuters.
Our current service offerings include Internet access from 128 Kbps to 1.54
Mbps, or up to 50 times faster than service provided over standard dial-up
telephone lines. Through two national independent contractors, we also provide
value-added services such as e-mail, Web hosting and design, and domain name
service.

     We believe we are well positioned to bring advanced wireless services to
our medium and small markets, due to the relatively large amount of spectrum (an
average of 151 MHz per market) that we hold. The ability to deploy broadband
services extensively throughout our markets primarily will depend on four
prerequisites: (1) receipt of FCC authorization, (2) protection of our existing
spectrum licenses from relocation, (3) availability of a commercially viable
technology platform, and (4) additional capital to maintain our spectrum and
fund construction and deployment of our network. We achieved the first of these
prerequisites in 2001 with the receipt of over 95% of our two-way digital
operating licenses for which we had applied from the FCC. The second
prerequisite was achieved with the FCC's order in September 2001 not to relocate
license holders in the 2.5 GHz band. We currently are focused on validating the
most efficient technical platform from which to deliver our services and, during
the next 12 months, we likely will seek to raise capital for spectrum
maintenance, operating expenses and/or to fund deployment. There can be no
assurance that additional capital will be available on acceptable terms or in a
timely manner.

     We currently do not plan to launch additional Internet markets with
existing first generation technology. We believe that a "next generation"
technology platform that (1) addresses line-of-sight limitations that exist in
current generation equipment, (2) allows customers to install and upgrade their
customer premises equipment ("CPE") themselves, and (3) is cost effective to
deploy, must become commercially available before launching broadband services
in additional markets. We completed our field trial with Cisco Systems, Inc.
("Cisco") last year. Although beta customer reaction to the trial was positive,
we do not expect Cisco to bring to market a technology platform for delivering
broadband services over MMDS spectrum. We currently are evaluating the
development of next generation MMDS technology platforms, including a new
technology trial in one of our markets. In addition, we are continuing to
monitor the commitments by other MMDS operators to next generation technology
platforms. For example, in October 2001, Sprint Corporation ("Sprint") announced
that it was ending customer acquisition for MMDS Internet services provided with
first generation equipment, and freezing the number of MMDS markets it serves
until substantial progress is made on next generation MMDS technology. We also
are evaluating the accessibility of capital markets, and the availability of
other sources of financing. Until we are able to deploy a next generation
technology platform for which another major MMDS operator has made a substantial
purchase commitment, and have obtained financing on satisfactory terms and
conditions, we intend to continue to look for efficiencies, maximize our
                                        3
<PAGE>

cash resources and preserve strategic spectrum resources. This likely will
result in deployment of no new Internet markets in 2002 and will likely postpone
deployment until another large MMDS operator makes a substantial purchase
commitment to a particular next generation technology platform. See Item 7,
"MD&A -- Future Cash Requirements" in this report.

     Historically, we have used our spectrum to provide wireless subscription
television services, commonly referred to as "wireless cable." We presently have
wireless cable transmission facilities constructed and operating in 57 markets
in eight states. At March 31, 2002, we had approximately 75,600 wireless cable
customers, including approximately 70,600 customers who subscribed only to
programming service provided over our MMDS spectrum, and 5,000 "combo"
subscribers who subscribed to both our MMDS programming service and to DIRECTV,
Inc. ("DIRECTV") programming service sold by us. In addition, at March 31, 2002,
there were approximately 23,900 customers who received only DIRECTV programming
sold by us.

     We have marketed and sold DIRECTV digital broadcast satellite programming
as a commissioned sales agent for DIRECTV since 1998. We currently market and
sell DIRECTV programming under an agreement with DIRECTV entered into in
February 2001. DIRECTV pays us an up-front and a residual commission for each
subscriber to whom we sell a DIRECTV programming package. We also receive
certain equipment subsidies from DIRECTV -- approved equipment providers. Our
agreement with DIRECTV expires in February 2006. The up-front commissions we
receive from DIRECTV are subject to a chargeback that we pay DIRECTV if the
subscriber terminates, cancels or disconnects service before the end of one
year. The amount of the chargeback is prorated based on the length of time
remaining in the one-year chargeback period. Residual commissions are payable to
us until the earlier of (1) disconnection or termination of the subscriber, (2)
termination or expiration of our agreement with DIRECTV, or (3) five years after
activation of the subscriber. Our failure to achieve certain subscriber
benchmarks during any calendar year of our agreement with DIRECTV would result
in a reduction of the residual commission for the next calendar year. This sales
agency agreement applies only to new DIRECTV subscribers procured by the
Company. The Company plans to convert its existing wireless cable subscribers to
satellite programming provided by DIRECTV and Pegasus Satellite Television, Inc.
("Pegasus"), and cable programming provided by an affiliate of Time Warner Cable
("Time Warner"). See "Business -- Conversion of Wireless Cable Business."

     Our business strategy contemplates a decline in wireless cable subscribers,
DIRECTV subscribers, revenues, and cash flows in 2002 and beyond, as we allocate
most of our resources to develop our broadband wireless Internet access and
other advanced wireless services. As a result of our previously announced
strategic shift in the use of our spectrum from analog video service to digital
broadband wireless Internet and other advanced wireless services, we expect to
convert our wireless cable subscriber base to DIRECTV and wired cable
programming by March 2003. Except for a nominal residual royalty and recognition
of deferred revenue related to cash received at the time of conversion, we do
not expect our existing wireless cable subscriber base to continue to generate
material revenues or cash flows for the Company beyond March 2003. See
"Business -- Nucentrix's Broadband Wireless Services -- Conversion of Wireless
Cable Business" in this report.

     We use our spectrum to transmit and/or receive signals between a base
station and transmit/receive equipment at each customer's location. We own or
lease an average of 151 MHz of spectrum in 95 markets,

                                        4
<PAGE>

plus 20 MHz of Wireless Cable Service ("WCS") spectrum at 2.3 GHz in 19 markets.
The chart below depicts the MDS, MMDS, ITFS, and WCS spectrum we own and lease.

CORPORATE INFORMATION

     Nucentrix was incorporated under the laws of the State of Delaware in
October 1993 under the name Heartland Wireless Communications, Inc. Nucentrix
emerged from a reorganization under Chapter 11 of the U.S. Bankruptcy Code on
April 1, 1999, and we changed our name on that date to Nucentrix Broadband
Networks, Inc. See "Business -- Reorganization." Our executive offices are
located at 4120 International Parkway, Suite 2000, Carrollton, Texas 75007, and
our telephone number is (972) 662-4000.

NUCENTRIX'S BROADBAND WIRELESS SERVICES

     In July 1998, we entered our first market in Sherman-Denison, Texas on a
developmental basis as a retail high-speed Internet service provider ("ISP"). We
initially offered a one-way wireless Internet access service using a six-MHz
MMDS channel for downstream transmission and a standard telephone line
connection for an upstream path. In August 1998, we received a temporary
developmental authorization from the FCC to conduct two-way operations in this
market and, in February 1999, we began offering high-speed two-way Internet
access over our MMDS spectrum.

     We launched high-speed Internet service in Austin, Texas in May 1999, also
under a temporary developmental authorization from the FCC. We currently offer a
variety of Internet services in Austin and Sherman-Denison, Texas for
medium-sized and small businesses, telecommuters, SOHOs, and residential
customers, which include:

     - Internet access at speeds from 128 Kbps to 1.54 Mbps,

     - technical support,

     - e-mail,

     - Web design and hosting,

     - domain name registration, and

     - domain name and maintenance.

CONVERSION OF WIRELESS CABLE BUSINESS

     Through our wireless cable business, we currently offer our subscribers
local off-air VHF/UHF channels from affiliates of ABC, NBC, CBS, and Fox, and
other local independent broadcast stations, as well as cable programming such as
HBO, HBO2, Cinemax, Showtime, Disney, ESPN, CNN, USA, TBS, Discovery, TNN, A&E,
and other programming. The channels and programming that we offer in each market
vary depending upon the spectrum capacity we have in such market. The preceding
marks are trademarks of the respective organizations and are not owned by us.

                                        5
<PAGE>

     In March 2002, as part of our long-term plan to focus on the use of our
spectrum for broadband Internet and other advanced wireless services, we
announced the signing of agreements with DIRECTV, Pegasus and Time Warner Cable
to convert substantially all of our wireless cable subscribers to programming
provided by these entities. Our agreements with DIRECTV and Pegasus are sales
agency agreements, under which we plan to market and sell DIRECTV programming
packages to our existing residential single family ("SFU") wireless cable
subscribers. In exchange for each subscriber converted to a DIRECTV programming
package, we will receive a conversion payment, equipment subsidy and
installation subsidy, which are payable on a per subscriber basis after
conversion. The Company also will receive a residual royalty payment for a
converted subscriber for as long as the subscriber receives DIRECTV programming,
up to three years. The conversion payment and subsidies that we receive from
DIRECTV are subject to a chargeback that we pay DIRECTV if the subscriber
terminates, cancels or disconnects service before the end of one year. The
amount of the chargeback is prorated based on the length of time remaining in
the one-year chargeback period. The conversion payment that we receive from
Pegasus is also subject to a chargeback that we pay Pegasus if the subscriber
terminates, cancels, disconnects, or downgrades service before the end of one
year. The amount of this chargeback may vary depending upon the length of time
remaining in the chargeback period and the type of programming package canceled
or downgraded by the subscriber. Residual commissions are payable to us by
DIRECTV and Pegasus until the earlier of (1) disconnection, termination or (in
the case of Pegasus) downgrade of a programming package or (2) three years after
activation of the subscriber. We estimate that approximately 63,000 of our SFU
wireless cable subscribers will be eligible for conversion under the DIRECTV and
Pegasus agreements. These agreements apply only to existing SFU wireless cable
subscribers who subscribe only to programming service provided over MMDS
spectrum, and not to our existing "combo" or DIRECTV subscribers. We intend to
discuss a similar agreement with DIRECTV and Pegasus for multiple dwelling unit
("MDU") subscribers in the second quarter of 2002.

     Our agreement with Time Warner Cable is an Asset Purchase Agreement, under
which we will (1) grant Time Warner Cable the right to market its cable service
to certain of our existing SFU subscribers and (2) assign to Time Warner Cable
certain of our agreements to provide video service to MDUs, along with related
equipment and wiring at the MDUs. In exchange for each subscriber converted, we
will receive a payment in the month following the conversion. We estimate that
approximately 6,000 total SFU and MDU subscribers, all in Central Texas, will be
eligible for conversion under this agreement.

     As a result of this strategic shift in the focus of our business, revenues
and cash flows from our wireless cable business will decline substantially as
our subscribers convert to DIRECTV, Pegasus or Time Warner Cable or otherwise
disconnect their service with us. Except for the nominal residual royalty
payment and recognition of deferred revenue related to cash received at the time
of conversion, we do not expect our existing wireless cable subscriber base to
generate material revenues or cash flows for the Company after March 2003.
Although we intend to reduce expenditures associated with our wireless cable
business, ongoing costs of maintaining our FCC spectrum licenses and leases, as
well as other corporate overhead, will exceed revenues as we implement the
conversion program. See Item 7, "MD&A -- Future Cash Requirements" in this
report.

MMDS LICENSES AND LEASES

     We hold the licenses granted by the FCC for approximately 83% of our MDS
and MMDS channels. We lease from third-party license holders the rights to (1)
the remaining 17% of our MDS and MMDS channels and (2) all of our ITFS channels,
which generally comprise 20 of the 33 channels available in each market. All MDS
and MMDS licenses expire in either 2006 or 2011. Approximately 50% of our
MDS/MMDS licenses are for BTA channels that expire in 2006; the other 50% are
"incumbent" channels that expire in May 2011. ITFS licenses generally have a
term of 10 years. All licenses are subject to renewal by the FCC as described in
"Government Regulation." Although FCC custom and practice establish a
presumption of granting renewals of licenses, the presumption requires that the
licensee substantially comply with its regulatory obligations during the license
period, including construction obligations.

     Each of our channel leases typically covers four ITFS channels or one to
four MDS/MMDS channels. The initial terms of our leases for ITFS channels
typically expire five to ten years after the license grant date,
                                        6
<PAGE>

but in any event may not exceed 15 years. The initial terms of the leases for
MDS/MMDS channels typically expire five to 10 years from the lease execution
date. The average remaining terms of most of our current ITFS and MDS/MMDS
channel leases, including all renewal terms, is 11 years. We believe that
substantially all of our MDS/MMDS channel leases allow for use of the spectrum
for two-way data transmission. Approximately 72% of our ITFS channel leases in
our top 40 projected Internet markets conform to the FCC's new rules for two-way
use of this spectrum. We believe that another 11% of these ITFS channel leases,
although entered into before the issuance of the two-way rules, would be
"grandfathered" under the FCC's rules and authorized for two-way use of the
spectrum.

     We also hold authorizations for 90 BTAs in which we have the exclusive
right to apply for and develop available MDS and MMDS frequencies, subject to
our lease of MDS/MMDS channels in 10 BTAs and portions of four other BTAs to CS
Wireless Systems, Inc. ("CS Wireless"). Additionally, current FCC regulations
require these BTAs to be built out by August 2003, at the earliest. See
"Government Regulation -- BTA Auction and Service Requirements."

MARKETS

     The following tables provide information as of March 31, 2002, regarding
the 95 markets in which we operate a wireless cable or broadband wireless
Internet system, own the BTA authorization or have acquired additional
MDS/MMDS/ITFS spectrum rights. Certain of our spectrum rights are subject to
pending applications for new channel licenses, modifications to existing channel
licenses or special temporary and developmental authorizations, and must be
reviewed by the FCC's engineering and legal staff.

     We estimate that the BTAs and 35-mile protected service areas in our
markets include approximately 9 million households. Estimated household
information is based on 1990 census bureau data and data from a commercially
available 2001 population projection database. The actual number of households
that can receive and/or transmit an adequate unobstructed signal may vary
significantly from this estimate based on a number of factors, including
transmitter height and power, topography and the proximity of adjacent MMDS
systems.

 +  Operating wireless cable market.

++  Operating broadband wireless Internet market.

(1) Unless otherwise noted, the number of channels available includes channels
    (a) that are either licensed to us or leased to us from other license
    holders or (b) for which we or our ITFS lessors have filed applications with
    the FCC that we expect to be granted in 2002. The number of channels
    available includes leased ITFS channels that may not currently be available
    for two-way broadband wireless services.

(2) We have entered into a definitive purchase agreement to acquire
    substantially all of the MDS, MMDS and ITFS spectrum rights in this market.
    In October 2001, the FCC dismissed the BTA owner's application for consent
    to assign the Rockford BTA to the Company. As a result, the Company or the
    BTA owner may terminate the purchase agreement, or the parties may determine
    to modify the agreement. In November 2001, the BTA owner filed a Petition
    for Reconsideration of the FCC's decision. If the parties determine to
    proceed, the transaction will be subject to other customary closing
    conditions including due diligence.

(3) Four ITFS channels are subject to applications pending proceedings at the
    FCC, which we believe will be granted.

(4) We have entered into a letter intent to acquire the MMDS incumbent licenses
    and ITFS spectrum leases in this market. This transaction is subject to the
    execution of definitive agreements and other customary closing conditions,
    including due diligence and FCC approval.

     In addition to MDS, MMDS and ITFS spectrum rights owned by Nucentrix, we
are a party to an agreement with CS Wireless under which CS Wireless agreed to
assign to us 20 MHz of WCS spectrum at 2.3 GHz in 19 markets, primarily in
Texas. We currently lease this spectrum under an exclusive lease agreement with
CS Wireless. Assignment of the WCS spectrum is subject to FCC approval.

NETWORKS/SUPPLIERS

     Our two-way, broadband wireless business is built around a network
comprised of many elements. At the core of our network is a broadband wireless
platform that controls when, where and how subscribers access our network and
data is transported over the air between subscriber premises and our services
networks (e.g., the Internet for data services, the Public Switched Telephone
Network for voice services). This core wireless access system is the focus of
our next generation technology validation process.

     On either side of this core wireless network are specific computer and
communications equipment components that are typically supplied by third party
vendors, and are necessary for a complete "end-to-end" system solution. These
components are generally commercially available, field proven technologies, such
as radio antennas, power amplifiers, point-to-point microwave equipment,
routers, gateways, switching equipment, and communication servers from vendors
such as AML Wireless Systems, Inc., Andrew Corporation,

                                        10
<PAGE>

Inc., Cisco Systems, Inc., Hewlett-Packard Company, Juniper Networks, Inc.,
REMEC, Inc., Sun Microsystems, Inc., and many others.

     First generation broadband wireless access platforms generally are
characterized by:

     - Broadband data rates, typically in excess of 384 Kbps in the upstream and
       downstream direction,

     - A single base station serving a large coverage area, generally up to 35
       miles,

     - Externally mounted CPE, professionally installed by the service provider,
       and

     - Line-of-sight constraints, in which a visual line of sight is required
       between the base station and the CPE.

     Next generation technology platforms, commonly referred to as "second
generation," or 2G, are expected to deliver broadband data rates, but will be
characterized by:

     - Multi-cellular architectures using smaller cells to improve both the
       coverage and capacity performance of the network,

     - Small, relatively inexpensive CPE that can be located within the
       residence or place of business, with little or no significant
       line-of-sight requirement, and typically installed or configured by the
       customer, and

     - Potential nomadic or portable broadband services.

     There currently are many vendors designing and building 2G platforms. These
vendors include Alvarion Ltd., Apuerto, BeamReach Networks, Inc., Com Dev
International Ltd., Iospan Wireless, Inc., IP Wireless, Inc., Navini Networks,
Inc., NextNet Wireless, Inc., Soma Networks, Inc., Wi-LAN Inc., and others. Each
of these vendors has made unique engineering choices in the fundamental design
of its system to best position its technology for success. These choices include
multiple access method (e.g., CDMA, OFDM), duplexing method (frequency division
duplexing and time division duplexing), and the use of advanced access
techniques such as adaptive modulation and smart antennas.

     During the second half of 2001, certain of these vendors began to
commercialize their platforms, taking them from the lab, to field trials, to
commercial production. As of the date of this report, there are several known 2G
networks in commercial service in the United States, with more planned for
commercial launch in the first half of 2002, both domestically and
internationally. While we are encouraged with the progress these vendors are
making, we expect the process of development, trial and commercial testing to
continue through the remainder of 2002 as vendors progress through this product
cycle. This will afford us and other MMDS operators the opportunity to
thoroughly evaluate, compare and contrast the commercial viability and business
case potential of the substantial majority of 2G platforms in field environments
before making our critical platform decision.

CUSTOMER SUPPORT

     We provide customer and technical support to our Internet and wireless
cable business through our existing base of technical services personnel and a
company-owned and operated centralized customer care center. We have contracted
with Critical Path, Inc., a leading provider of Internet messaging solutions for
ISPs, for certain e-mail functions. ISP Alliance, Inc., a leading supplier of
systems and operational support for ISPs, provides Web design and hosting,
domain name registration and maintenance on a "pay as used" basis.

COMPETITION

  HIGH-SPEED INTERNET COMPETITION

     The Internet access market is highly competitive. We face competition from
many Internet access and service providers with significantly greater financial
resources, well-established brand names and large, existing customer bases. Our
competition in this industry includes:

     Internet Service Providers.  ISPs provide Internet access to residential
and business customers. These companies can:

     - provide Internet access over incumbent local exchange carriers' ("ILECs")
       networks at high speeds,

     - offer digital subscriber line ("DSL")-based access using their own DSL
       services, or DSL services offered by ILECs and others, and

     - have significant and sometimes nationwide marketing presences and combine
       these with strategic or commercial alliances with DSL-based incumbent and
       competitive carriers. Significant ISPs include AOL Time Warner, Inc.
       ("AOL"), Microsoft Corporation and EarthLink, Inc.

     Incumbent Local Exchange Carriers.  ILECs, such as SBC Communications, Inc.
Verizon Communications, Inc. and Qwest Communications International, Inc.
("Qwest") have existing metropolitan area networks and circuit-switched local
access networks. Most incumbent carriers have deployed commercial DSL services
in certain areas and are combining their DSL service with their own Internet
access services. The incumbent carriers generally have an established brand name
in their service areas and possess sufficient capital to deploy DSL services
rapidly.

     Interexchange Carriers.  Many of the interexchange carriers, such as AT&T
Corporation, WorldCom, Inc. ("WorldCom") and Sprint, have the capability to
support high-speed, end-to-end networking services. These carriers have deployed
large scale networks, have large numbers of existing business and residential
customers and enjoy strong name recognition. These companies increasingly are
bundling their services to include high-speed local access combined with
metropolitan and wide area networks, and a full range of Internet services and
applications. Other carriers, such as Qwest and Level 3 Communications, Inc.,
are building or managing high-capacity, nationwide IP-based networks and
partnering with ISPs to offer a range of services to businesses and consumers.

     Cable Modem Service Providers.  Cable modem service providers, like the
Time Warner Cable division of AOL, AT&T Broadband Corp., Comcast Corporation,
and Cox Communications, Inc., among others, currently offer consumers and
businesses high-speed Internet access over hybrid fiber coaxial cable networks.
Where deployed, these networks provide local access services similar to our
services, and in some cases at higher speeds.

     Satellite and Other Fixed Wireless Providers.  We will face competition
from satellite-based systems. Hughes Network Systems, a unit of Hughes
Electronics Corporation (through its DIRECWAY and DirecPC brands), and StarBand
Communications, Inc. (owned by Gilat Satellite Networks, Ltd., Microsoft
Corporation and EchoStar Communications Corporation ("EchoStar")) have announced
deployment of two-way broadband satellite service. In addition, many local and
regional ISPs use unlicensed spectrum to offer terrestrial fixed wireless
high-speed Internet access.

     Competitive Local Exchange Carriers.  We expect competitive local exchange
carriers ("CLECs") to offer DSL-based data services. Traditional CLECs,
including Allegiance Telecom, Inc., have extensive fiber-based networks in
numerous metropolitan areas and are capable of providing voice and high-speed
data services to businesses.

     3G Wireless.  We also expect more competition from 3G wireless providers,
as commercial mobile radio service providers begin to deploy 3G services in
their spectrum bands. The successful deployment of 3G wireless services could
significantly expand the availability of broadband services, especially to
consumers that currently are unserved by wireline connections.

                                        12
<PAGE>

     Many of these competitors are offering, or may soon offer, technologies and
services that will directly compete with some or all of our service offerings.
We may not be able to compete effectively, especially against established
industry competitors with significantly greater financial resources. We believe
the principal competitive factors that we face include:

     - transmission speed,

     - reliability of service,

     - ability to bundle services,

     - price performance,

     - customer support,

     - brand recognition,

     - operating experience, and

     - capital availability.

     For a further discussion of competition in this industry, see
"Business -- Risk Factors -- The Internet access market is highly competitive.
Because many competitors in our markets are well-established and have resources
significantly greater than those available to us, we may not be able to
establish a significant number of Internet access customers in our markets."

  OTHER TELEPHONY SERVICES

     We also will face intense competition from other providers of telephony
transmission services as we implement wireless telecommunications services and
voice over IP. This competition will be increased because MMDS spectrum
traditionally has not been used to deliver telephony services, and consumer
acceptance of such services delivered across MMDS spectrum is unknown at this
time. Many of the existing providers of telephony services, such as ILECs and
CLECs, have significantly greater financial and other resources than us and
better established brand awareness in their service areas.

GOVERNMENT REGULATION

     General.  MDS, MMDS and ITFS services are subject to regulation by the FCC
under the Communications Act of 1934, as amended ("Communications Act"). The
Communications Act authorizes the FCC, among other things, to;

     - issue, revoke, modify, and renew station licenses,

     - approve the assignment and/or transfer of control of such licenses,

     - approve the location and technical parameters of MDS, MMDS and ITFS
       transmission facilities (headends and base stations),

     - regulate the kind, configuration and operation of equipment used by MDS,
       MMDS and ITFS systems,

     - impose certain equal employment opportunity and other periodic reporting
       requirements on MDS, MMDS and ITFS operators, and

     - review and approve/disapprove certain terms of airtime lease agreements.

     MDS, MMDS and ITFS Licenses.  In our markets, a total of 32 six-MHz
channels and one four-MHz channel are available in the MDS, MMDS and ITFS
frequency bands. The FCC can license the 13 MDS and MMDS channels directly to
commercial entities for full-time operation without service restrictions. Except
in limited circumstances, the FCC generally can license 20 ITFS channels only to
qualified non-profit educational organizations. When using analog transmissions,
each of the ITFS channels must broadcast programming for educational purposes a
minimum of 20 hours per week. The remaining air time on ITFS channels may be
leased for commercial use, without further programming restrictions except that
the ITFS
                                        13
<PAGE>

license holder, at its option, must be entitled to recapture up to an additional
20 hours of air time per channel per week for educational programming. When
using digital transmissions, an ITFS licensee must reserve 5% of the capacity of
each 6 MHz channel for immediate ITFS use upon request. There is no additional
recapture requirement for an ITFS licensee when using digital transmissions.

     The FCC established MDS/MMDS spectrum in 1974 with the allocation of two
channels (MDS-1 and MDS-2/2A). In 1983, the FCC reallocated a total of eight
ITFS channels to MMDS to satisfy a growing demand for the delivery of video
entertainment programming to subscribers and to provide competition to hardwire
cable television systems. Simultaneous with this reallocation of spectrum, the
FCC amended its rules for the remaining ITFS channels to permit ITFS licensees,
subject to their meeting certain educational programming requirements, to lease
excess capacity to commercial MMDS service providers. ITFS channels originally
had been allocated solely for educational purposes.

     In 1985, the FCC established a lottery procedure for awarding MDS and MMDS
station licenses. In 1990, the FCC shifted to a one-day cut-off period
application process, under which all mutually exclusive MDS and MMDS licenses
were issued on essentially a first-come, first-served basis. In 1995, the FCC
adopted rules under which MDS and MMDS applications for new stations would be
subject to a competitive bidding process, or spectrum auction. The FCC generally
considers applications to be mutually exclusive if the grant of one application
would effectively preclude the grant of one or more of the other applications
due to interference that cannot be avoided through cooperation of the parties.
Using the competitive bidding process, in 1996 the FCC auctioned off one
authorization for each of the 493 BTAs. Each BTA authorization holder is
permitted to apply for, and following FCC grant, to construct facilities to
provide services over any unlicensed MDS or MMDS channel within the BTA, and has
preferred rights to the available ITFS frequencies within the BTA, subject to
the superior rights of any qualified ITFS applicant. The MDS and MMDS licenses
issued or applied for before the BTA auction are commonly referred to as
"incumbent" MDS/MMDS licenses, while the MDS and MMDS station authorizations
issued pursuant to BTA ownership are commonly referred to as "BTA" MDS/MMDS
licenses.

     The application and licensing process for ITFS stations is different from
those for MDS and MMDS stations. In 1995, the FCC adopted a national filing
window system. Under this system the FCC accepts applications for licenses for
new ITFS stations or major changes to existing ITFS licenses only if they are
filed within specific windows, typically five days, set by the FCC. Applications
filed in a particular window are subject only to competing proposals filed in
that same window. Where two or more applications are filed within the same
window and are predicted to cause each other harmful electrical interference,
licenses are awarded by the FCC pursuant to a comparative selection process.

     In 1998, the FCC, acting pursuant to the Balanced Budget Act of 1997,
tentatively concluded that competing ITFS applications should be subject to
auction, or competitive bidding. However, because the FCC was uncertain at the
time whether its conclusion correctly reflected Congress's intent with regard to
the treatment of competing ITFS applications, it decided not to proceed
immediately with the auction of ITFS applications and to first seek
Congressional guidance on the matter. In April 1999, having received no specific
guidance from Congress, the FCC reaffirmed its previous decision to use spectrum
auctions to resolve competing ITFS applications. The FCC did, however, state
that it would amend its rules regarding ITFS auctions if Congress were to
specify a change to the FCC's auction authority in this regard.

     Generally, in the case of MDS, MMDS and ITFS stations, the FCC issues the
station licensee a conditional license, allowing construction of the station to
commence. The station may be constructed and operated only in accordance with
the parameters set forth in the license. Channel transmission generally must
begin within one year of grant of the conditional license in the case of
incumbent MDS/MMDS licenses, 18 months in the case of ITFS licenses and by
August 2003 for BTA MDS/MMDS licenses. If channel construction deadlines for a
license are not met, then (1) the FCC may revoke the license or (2) in the case
of the BTA licenses, reduce the license service area if less than two-thirds of
the population of the BTA service area is capable of being reached by a station
signal by the expiration of the seven-year BTA build-out period. Although FCC
rules permit parties to request extensions of channel construction deadlines,
the FCC is not required to grant extensions. We believe that we have satisfied
all construction deadlines relating to our

                                        14
<PAGE>

licensed stations except for those licenses for which the deadline has not yet
passed or for which we have received an extension.

     MDS, MMDS and ITFS licenses generally have terms of 10 years. All BTA
MDS/MMDS licenses expire on March 28, 2006. All incumbent MDS/MMDS licenses
expire on May 1, 2011. Licenses may be renewed through applications filed with
the FCC within a certain period before expiration of the license term, and
petitions to deny applications for renewal may be filed by other parties during
certain periods following the filing of such applications. The FCC may revoke or
cancel licenses for violations of the Communications Act or the FCC's rules and
policies, whether or not related to the license under review. Alien ownership
exceeding prescribed levels and conviction of certain criminal offenses may also
render a licensee or applicant unqualified to hold a license. Although FCC
custom and practice establish a presumption granting renewals of licenses, the
presumption requires that the licensee substantially comply with its regulatory
obligations during the license period.

     FCC rules generally prohibit the sale for profit of an MDS or MMDS
conditional license or of a controlling interest in the conditional license
holder before construction of the station or, in certain instances, prior to the
completion of one year of operation. However, access to channels may be obtained
during these prohibited periods through the leasing of an MDS or MMDS license
holder's channel capacity. The granting of options to purchase a controlling
interest in a licensee or an option to purchase a license is also permitted
during these prohibited periods. During the lifetime of any such lease or option
agreement, the licensee must remain in control of its FCC license to avoid
violating FCC transfer-of-control rules. Our lease agreements with license
holders typically require the license holders, at our expense, to use their best
efforts, in cooperation with us, to make various required filings with the FCC
in connection with the maintenance and renewal of licenses. We believe this
reduces the likelihood that the FCC will revoke, cancel or fail to renew a
license.

     BTA Auction and Service Requirements.  In 1996, the FCC concluded its first
auction of available commercial MMDS spectrum in the 493 BTAs. Under the FCC's
rules, certain qualified small business auction winners, called "designated
entities," were permitted to pay off winning bids in installment payments. The
winner of a BTA has the exclusive right to apply for and develop the available
MDS and MMDS frequencies in the BTA, subject to certain specified interference
criteria that protect incumbent MDS and MMDS stations. Incumbent licensees also
must protect the BTA licensees from system interference caused by modifications
to incumbent stations, including power increases or base station relocations.

     BTA auction winners with MDS/MMDS spectrum rights have a "build-out" period
through August 2003. During the build-out period, a BTA holder can initiate or
expand service within its BTA without competition from other MDS/MMDS spectrum
applicants except in those areas and on those channels for which there is an
incumbent MDS/MMDS licensee. After the build-out period, a BTA holder can retain
its authorization for an entire BTA if its signal is capable of covering at
least two-thirds of the population within its BTA service area, excluding those
who are located within the protected service areas of incumbent MDS/ MMDS
stations licensed to others. If the BTA holder fails to meet the coverage
requirement after the build-out period, or the FCC does not waive, extend or
otherwise modify the build-out requirement, then the BTA license for the portion
of the BTA that is not capable of being served will be subject to forfeiture.
The FCC's rules allow BTAs to be partitioned and BTA licensees are permitted to
contract with other entities to allow them to file applications with the FCC for
available spectrum within the partitioned area. We expect the FCC to renew BTA
licenses after the expiration of their 10-year term if the authorization holder
satisfies the coverage requirement and is in compliance with the Communications
Act and the FCC's rules.

     BTAs.  We hold authorizations for 90 BTAs acquired in the 1996
auction.Failure to remit installment payments in a timely manner or to meet the
build-out deadlines could result in the forfeiture of some or all of the BTA
authorizations that we hold. We believe that we have satisfied the applicable
financial and coverage requirements, or that the FCC will waive, extend or
otherwise modify the build-out requirement, to allow us to retain substantially
all our BTA authorizations in which we intend to operate. In October 1997, we
entered into a lease and purchase option agreement with CS Wireless for BTA
channels in 10 BTAs and portions of four additional BTAs already licensed to us.
Under this agreement, CS Wireless has agreed to reimburse us

                                        15
<PAGE>

for all amounts paid to the FCC for the BTAs leased to CS Wireless. The
agreement also provides CS Wireless the option to purchase the leased BTA
channels.

     WCS Licenses.  In February 1997, the FCC reallocated and assigned the use
of the frequencies at 2305-2320 MHz and 2345-2360 MHz to WCS. WCS licensees are
permitted to provide fixed, mobile and radio location services throughout their
2.3 GHz band. In addition, satellite digital audio radio service ("SDARS") may
be provided on all frequencies in the band except for those at 2305-2310 MHz.
WCS licenses, which generally are awarded by the FCC through competitive
bidding, have terms of 10 years. Although the licenses carry with them a
"renewal expectancy," each WCS licensee is subject to certain "substantial
service" requirements that must be met during the initial license term.
"Substantial service" is defined by the FCC as "service which is sound,
favorable, and substantially above the level of mediocre service which just
might minimally warrant renewal." Failure by a licensee to meet this requirement
may result in a forfeiture of its license. We lease 20 MHz of WCS spectrum in 19
markets from CS Wireless. However, some SDARS providers have proposed to deploy
an extensive network of land-based repeaters that, if authorized by the FCC,
could create interference that substantially impairs the use of WCS spectrum for
two-way Internet, data and other services.

     Transmission.  The FCC also regulates transmitter locations and signal
strengths. The operation of an MDS, MMDS and ITFS system typically requires the
co-location of a commercially viable amount of spectrum operating under common
technical characteristics. To co-locate spectrum, an applicant must demonstrate
that its proposed signal does not violate interference standards in the
FCC-protected area of previously-authorized MDS, MMDS and ITFS stations. An MDS
and MMDS license holder generally is protected from interference from another
MDS or MMDS operator within a 35-mile radius of the base station called a
"protected service area." An ITFS license holder generally is entitled to
protection from electrical interference to all of its receive sites. In
addition, an ITFS station is entitled to a 35-mile protected service area (1)
during the use of the station's excess channel capacity by an MMDS operator if
it has requested and received a protected service area from the FCC or (2) from
all MDS, MMDS and ITFS station licensees that implement two-way digital
operations.

     Two-Way Authorization.  In September 1998, the FCC amended its rules to
allow for the use of MMDS spectrum for two-way digital services, including
high-speed Internet, data, voice, and video services. As amended, these rules
are referred to as the "two-way rules." The two-way rules are intended to
provide licensees and operators in the MDS, MMDS and ITFS spectrum with the
technical and operational flexibility to add various digital two-way services to
their current offerings. The two-way rules permit the use of MDS, MMDS and ITFS
frequencies for both downstream and response transmissions. Two-way service is
provided through the use of "response" stations, such as at the customer's
premises, and response station "hubs," or base stations, which serve as
collection points for response transmissions. The two-way rules also permit a
cellular system design using a "signal booster station," or additional
transmission site not located at the base station, which is used either to
originate or relay signals to customers and also serve as a response station hub
for those customers.

     Under the two-way rules, all MDS, MMDS and ITFS spectrum generally can be
used for upstream or downstream communications. All spectrum will continue to be
subject to the FCC's interference protection requirements and existing or future
spectrum capacity lease agreements. In addition, MDS, MMDS and ITFS operators
that operate digital two-way communications systems are permitted, subject to
certain limitations, to "shift" required ITFS educational programming to any
MDS, MMDS or ITFS channel within the same operating system, "load" ITFS
programming on to less than the total number of channels licensed to a
particular ITFS licensee or "swap" their spectrum for other spectrum in the same
market. However, channel swaps represent changes in licensees and require the
filing of applications with the FCC and receipt of FCC approval.

     The FCC opened an initial one-week filing window for two-way applications
in August 2000. We filed over 400 applications for 70 markets in this filing
window. We have received FCC licenses for over 95% of these applications,
representing 90% of these markets. These licenses cover our top 30 projected
Internet markets.

                                        16
<PAGE>

     Flexible Use Authorization.  In September 2001, after a period of study of
almost one year to identify additional spectrum for 3G wireless services, the
FCC decided not to relocate incumbent license holders and operators in the 2.5
GHz band, such as the Company, to other frequency bands. In connection with this
decision, the FCC also added a flexible use allocation to the 2.5 GHz band,
making this band available for advanced mobile services, including 3G wireless
systems. The flexible use allocation is subject to the protection of existing
fixed wireless licenses in the 2.5 GHz band from interference.

     Regulation of Internet Service Providers.  Congress has passed a number of
laws that concern the Internet, including the Digital Millennium Copyright Act,
the Children's Online Privacy Protection Act, the Children's Online Protection
Act, and the Protection of Children from Sexual Predators Act of 1998.
Generally, these laws provide liability limitations for Internet service
providers that do not knowingly engage in unlawful activity. We do not
anticipate that compliance with these laws will have an adverse impact on us.
However, we may be required to implement operating guidelines to comply with the
laws and could be subject to liability if we fail to implement appropriate
guidelines or otherwise violate any of these new laws.

     Aside from the use of spectrum, the FCC has held that Internet access
services are "information services" not subject to FCC regulation. Nevertheless,
the FCC has held that Internet dial-up traffic is interstate traffic subject to
FCC jurisdiction. Although the U.S. Court of Appeals for the D.C. Circuit
reversed and remanded that decision, the FCC has reaffirmed the holding on
remand. The FCC's affirmation of its holding is currently being appealed.

     There can, therefore, be no certainty that the providing of Internet access
services will continue to be free from FCC regulation.

     Regulation of Telecommunications Services.  If we begin providing wireless
telecommunications services or voice over IP services, we may be subject to a
variety of FCC and state regulation of our interstate and intrastate
telecommunications services, respectively. Although the FCC currently does not
consider voice over IP services to be telecommunications services, and thus does
not regulate them as such, this position could change. Moreover, the regulatory
status of voice over IP is unsettled at the state level. If we begin providing
voice over IP, we may be subject to regulation in some states but not in others.

     The Cable Act.  On October 5, 1992, Congress passed the Cable Television
Consumer Protection and Competition Act of 1992 (the "Cable Act"). Pursuant to
the Cable Act, effective October 6, 1993, commercial broadcasters may require
cable operators and other multichannel video service providers to obtain their
consent before retransmitting their signals. The FCC has exempted wireless cable
providers from the retransmission consent rules if the receive-site antenna is
either owned by the subscriber or within the subscriber's control and available
for purchase by the subscriber upon the termination of service. In all other
cases, wireless cable providers must obtain consent to retransmit broadcast
signals. We believe that we have obtained substantially all consents required to
retransmit local broadcast signals in our subscription television markets. We
cannot assure you that existing consents will be maintained or renewed or that
we will be able to obtain any additional necessary consents on terms
satisfactory to us, if at all. Unlike hardwire cable systems, wireless cable
systems are not required under the Cable Act and the FCC's "must carry" rules to
retransmit a specified number of local commercial and non-commercial television
or qualified low power television signals.

     Copyright.  Under the Federal copyright laws, permission from the copyright
holder generally must be secured before certain video programs may be
retransmitted. Under Section 111 of the Copyright Act of 1976, certain "cable
systems," including wireless cable providers, are entitled to engage in the
secondary transmission of broadcast programming without the prior permission of
the holders of copyrights in the programming if a compulsory copyright license
is secured. Such a license may be obtained upon the filing of certain reports
and the payment of certain fees set by copyright arbitration royalty panels. We
believe we have obtained all compulsory copyright licenses required for each of
our subscription television markets.

     In 1994, Congress enacted legislation that clarified the ability of
wireless cable providers to obtain the benefit of the Section 111 compulsory
copyright license. Periodically, Congress has considered proposals to phase out
the Section 111 compulsory license. In response to a request from Congress, the
U.S. Copyright Office held a public hearing on the issue of compulsory licenses
in May 1997 and endorsed eventual

                                        17
<PAGE>

replacement of the statutory license by a free market negotiated license while
recommending retention of the existing license for the near future. There can be
no assurances that Congress will not adopt legislation affecting this or other
recommendations. Because our wireless cable systems retransmit only a limited
number of broadcast channels, we do not believe that the termination of the
compulsory copyright license would have a material adverse effect on our
financial condition, results of operations or cash flows.

     Other Regulations.  As a lessee of antenna structure space, we indirectly
(through contractual commitments) may be subject to Federal Aviation
Administration regulation and FCC registration for the construction, maintenance
and lighting of transmission towers and by certain local zoning regulations
affecting construction of towers and other facilities. Federal environmental
regulations and state and local environmental land use, and zoning regulations
also may apply.

TRANSACTIONS

     Beaumont/Port Arthur, Texas Acquisition.  In April 2002, we signed a letter
of intent to acquire the MMDS incumbent licenses and ITFS spectrum leases in
Beaumont/Port Arthur, Texas in a Chapter 11 bankruptcy proceeding, for $300,000
in common stock of the Company as of the date of closing. This transaction is
subject to execution of definitive agreements and customary closing conditions,
including due diligence and FCC approval.

     Fayetteville and Fort Smith, Arkansas Acquisition.  In April 2001, the
Company completed the purchase of certain of the MMDS spectrum licenses, leases
and related assets of Smithco of Ft. Smith, Inc. and Smithco Investments of West
Memphis, Inc., in Fort Smith, Arkansas in exchange for the issuance of
approximately 153,000 shares of common stock of the Company, valued at $4.2
million as of the date of filing of our Form 10-Q for the first quarter of 2001,
in which we initially announced this transaction, and $1.7 million as of the
date of closing. The 153,000 shares of common stock includes up to approximately
16,000 shares issuable over two years. In addition, the Company entered into new
MDS spectrum leases for three channels (18 MHz) in Fort Smith and new ITFS
spectrum leases for 20 channels (120 MHz) in each of Fort Smith and
Fayetteville, Arkansas. The Company also assumed a lease and purchase agreement
for four MMDS channels (24 MHz) in Fort Smith that provides for the payment of
$337,000 in cash through September 2002.

     Rockford, Illinois Acquisition.  In May 2000, the Company entered into a
definitive agreement to acquire all of the MDS, MMDS and ITFS spectrum licenses,
lease rights and other assets of Wireless Cable of Rockford, LLC and Allen Leeds
in Rockford, Illinois. In October 2001, the FCC dismissed the BTA owner's
application for consent to assign the Rockford BTA to the Company. As a result,
the Company or the BTA owner may terminate the purchase agreement, or the
parties may determine to modify the agreement. In November 2001, the BTA owner
filed a Petition for Reconsideration of the FCC's decision. If the parties
determine to proceed, the transaction will be subject to other customary closing
conditions including due diligence.

SPECTRUM ALLOCATION PROCEEDINGS FOR ADVANCED WIRELESS SERVICES

     In the fourth quarter of 2000, the FCC and other government organizations
initiated proceedings to study, identify and authorize additional radio
frequencies for advanced wireless services, including 3G mobile wireless
services. Several frequency bands were studied in this process. One of the
frequency bands under consideration for such services was the 2.5 GHz band, in
which we hold substantially all of our MDS/ MMDS/ITFS wireless FCC licenses and
spectrum leases. In September 2001, the FCC adopted an order not to relocate
incumbent license holders and operators in the 2.5 GHz band, such as Nucentrix,
to other frequency bands. The FCC also added a flexible use allocation to the
2.5 GHz band, making this band available for advanced mobile services, including
3G wireless systems. The flexible use allocation is subject to the protection of
existing fixed wireless licenses in the 2.5 GHz band from interference.

     The 2.1 GHz band, however, remains under consideration by the FCC for
relocation for 3G services. We currently use the 2.1 GHz band for upstream
transmissions in our existing wireless networks, and the 2.1 GHz band is part of
our plan for future broadband wireless networks. We could be required to
relocate current and
                                        18
<PAGE>

future broadband wireless services in the 2.1 GHz band to another frequency
band. We are not able to determine at this time the impact that relocation would
have on our operations; however, relocation of operations to another frequency
band could require new or additional equipment, raise operating costs, delay the
provision of service, or render service uneconomic in certain areas.

TRADEMARKS

     We own common law trademark rights in and have United States trademark
registrations on the trademarks NUCENTRIX BROADBAND NETWORKS, CYBERWAVE,
HEARTLAND WIRELESS COMMUNICATIONS, INC., HEARTLAND WIRELESS COMMUNICATIONS, INC.
and design, HEARTLAND CABLE TELEVISION, and in the stylized mark HEARTLAND. We
also own common law rights in, and have federal registrations pending in the
United States for, the marks NUCENTRIX, NUCENTRIX TELECOM and THINK FAST. We
consider these intellectual property rights important to our business.

EMPLOYEES

     As of March 31, 2002, we had approximately 300 employees. None of our
employees is subject to a collective bargaining agreement. We have experienced
no work stoppages and believe that we generally have good relations with our
employees. We also use the services of independent contractors in our wireless
cable systems.

REORGANIZATION

     On December 4, 1998, we filed a voluntary, prenegotiated Plan of
Reorganization (the "Plan") and disclosure statement under Chapter 11 of the
U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the District of Delaware
(In re Heartland Wireless Communications, Inc., Case No. 98-2692 (JJF)). We
filed the Plan with the prepetition agreement from the holders of more than 70%
in principal amount of our $115 million 13% senior notes and $125 million 14%
senior notes to support the Plan. On March 15, 1999, the Bankruptcy Court
confirmed our Plan, which became effective on April 1, 1999 (the "Effective
Date"). As of the Effective Date we changed our name from Heartland Wireless
Communications, Inc. ("Heartland"), to Nucentrix Broadband Networks, Inc.

     As of the Effective Date:

     - all previously issued and outstanding common stock, options granted under
       our stock option plans, warrants and any other equity interests in
       Nucentrix were canceled,

     - holders of our senior notes received 9,700,000 shares of newly issued
       common stock, and

     - holders of $40.2 million of convertible subordinated notes received
       300,000 shares of newly issued common stock and warrants to purchase
       825,000 shares of common stock at an exercise price of $27.63 per share,
       subject to downward adjustment in the event of a sale or merger of the
       Company.

     We are obligated under the Plan to issue warrants to acquire an additional
275,000 shares of common stock at an exercise price of $27.63 per share, subject
to downward adjustment in the event of a sale or merger of the Company. These
warrants will be allocated pro rata to holders of our common stock. We expect
these warrants to be issued in the second quarter of 2002. We also have been
required to issue additional shares of common stock to settle miscellaneous
unsecured claims under our Plan. As of March 31, 2002, we had issued 27,810
shares of our common stock to settle these claims. Based on information
currently available to us, we believe we will not be required to issue more than
5,000 additional shares of common stock to settle these miscellaneous unsecured
claims.

     In December 2000, several former stockholders of Heartland filed a lawsuit
against certain of our current and former directors and officers, to whom we may
have indemnity obligations, and former holders of senior notes, in the District
Court for Bryan County, Oklahoma. See Item 3, "Legal Proceedings." The
plaintiffs allege that the defendants purposely undervalued our enterprise value
as part of the Plan confirmation process

                                        19
<PAGE>

in order to extinguish all prepetition equity holders' interests. In June 2001,
the U.S. Bankruptcy Court for the District of Delaware granted the Company's
motion to enforce the Plan, and ordered that the plaintiffs dismiss this lawsuit
with prejudice. Plaintiffs have appealed the decision of the Bankruptcy Court to
the U.S. District Court for the District of Delaware. We believe the lawsuit is
without merit and intend to vigorously defend the lawsuit on behalf of our
current and former director and officer defendants.

RISK FACTORS

     Our business operations and the implementation of our long-term business
strategy are subject to significant risks inherent in our business, including,
without limitation, the risks and uncertainties described below. The occurrence
of any one or more of the risks or uncertainties described below could have a
material adverse effect on our financial condition, results of operations and
cash flows. Additionally, further discussion of these risk factors and other
risks may be found in Item 7, "MD&A" and elsewhere in this Item 1.

  WE MAY NOT BE ABLE TO OBTAIN THE ADDITIONAL FINANCING NECESSARY TO IMPLEMENT
  OUR LONG-TERM BUSINESS STRATEGY ON SATISFACTORY TERMS AND CONDITIONS.

     To implement our long-term business strategy, we will need additional
capital for capital expenditures, operating expenses, system development costs,
and acquisition costs, including debt that may be assumed in future
acquisitions. We plan to finance these activities by debt or equity financings,
secured or unsecured credit facilities, vendor financing, sales of assets, joint
ventures, or other arrangements. We cannot assure you that we will be able to
obtain the financing we will need to fund the implementation of our long-term
business strategy on satisfactory terms and conditions, if at all. If we incur
additional debt, we may have to dedicate a substantial portion of our cash flow
from operations to the payment of principal and interest, which may cause us to
be more vulnerable to competitive pressures and economic downturns. Our failure
to obtain additional financing in a timely manner and on acceptable terms would
adversely affect our ability to continue as a going concern and may require us
to delay, reduce or eliminate the launch of new high-speed Internet access
systems or sell some or a substantial portion of our assets.

  WE ARE PURSUING A NEW BUSINESS THAT WE HAVE NOT PREVIOUSLY OPERATED ON A LARGE
  SCALE. WE MAY NOT BE ABLE TO SUCCESSFULLY IMPLEMENT OUR LONG-TERM BUSINESS
  STRATEGY OR REVERSE OUR HISTORY OF LOSSES.

     We historically have used our radio spectrum to provide wireless cable
services and incurred substantial operating and net losses from these
operations. The principal focus of our long-term business strategy currently is
to transition the use of our MDS, MMDS and ITFS radio spectrum to provide
broadband wireless services, such as high-speed Internet access. We have
launched commercial high-speed Internet access service in only two of our
markets, and the revenues that we have received in these two initial markets are
immaterial to date (approximately 1% of consolidated revenues in 2001). When we
determine to deploy additional markets, we intend to increase our capital
expenditures to develop and launch broadband wireless services in additional
markets, and we expect operating expenses from our broadband wireless operations
to exceed revenues from those operations until our customer base increases. As a
result, we anticipate that our net and operating losses will continue until we
successfully implement our business strategy. We cannot assure you that we can
develop, market and expand our broadband wireless services in the two initial
markets or any additional markets to the extent necessary to successfully
compete in the broadband services industry.

  WE CANNOT ASSURE YOU THAT THE NEXT GENERATION TECHNOLOGY FOR OUR NETWORK
  PLATFORM WILL PROVIDE THE BENEFITS THAT WE NEED TO BE COMPETITIVE WITH OTHER
  BROADBAND SERVICE PROVIDERS, OR THAT IT WILL BE READY FOR COMMERCIAL
  DEPLOYMENT IN A TIMELY MANNER. IF THIS TECHNOLOGY PROVES UNRELIABLE, OR DOES
  NOT BECOME COMMERCIALLY VIABLE IN TIME TO MEET PERCEIVED DEMAND, THEN DEMAND
  FOR OUR SERVICES AND OUR ABILITY TO TIMELY IMPLEMENT OUR LONG-TERM BUSINESS
  STRATEGY COULD BE ADVERSELY AFFECTED.

     We currently are evaluating the development of next generation technology
platforms for delivery of broadband wireless service over MMDS radio spectrum,
as well as the technology commitments by other MMDS operators such as Sprint and
WorldCom. We believe some of these technology platforms will address
line-of-sight limitations that exist in current generation equipment, and allow
customers to install and upgrade
                                        20
<PAGE>

their customer premises equipment themselves. However, next generation MMDS
technology is largely unproven in commercial applications. We cannot assure you
that new technology will provide the advantages we expect or that it will be
ready for commercial deployment in a timely manner, if at all. Our failure to
achieve or maintain reliable service capabilities could significantly reduce or
delay consumer demand for our services. In addition, it is unlikely that we
would commit to a specific technology platform for any significant deployment
until another major MMDS operator makes a significant commitment to the same
technology. In October 2001, Sprint announced that it was ending customer
acquisition for MMDS Internet services and freezing the number of MMDS markets
it serves until substantial progress is made on next generation MMDS technology.
The failure of a technology platform to become commercially ready in a timely
manner could delay, reduce or eliminate our launch of new broadband wireless
Internet systems.

  WE EXPECT THAT OPEN TECHNOLOGY STANDARDS AMONG MMDS EQUIPMENT MANUFACTURERS
  WILL LOWER EQUIPMENT AND OTHER COSTS FOR SERVICE PROVIDERS. THERE IS NO
  ASSURANCE THAT THESE STANDARDS WILL EVOLVE.

     We believe that open, or non-proprietary, manufacturing standards
ultimately are necessary in next generation MMDS technology to lower
infrastructure and customer premise equipment costs, and allow for
interoperability and flexibility for service providers. Although there are
discussions among various vendors to develop open standards in this area, there
is no assurance that these standards will evolve in the near future or at all.
The failure of these standards to evolve could result in higher operating costs
and unacceptable operating margins.

  THE INTERNET ACCESS MARKET IS HIGHLY COMPETITIVE. BECAUSE MANY COMPETITORS IN
  OUR MARKETS ARE WELL-ESTABLISHED AND HAVE RESOURCES SIGNIFICANTLY GREATER THAN
  THOSE AVAILABLE TO US, WE MAY NOT BE ABLE TO ESTABLISH A SIGNIFICANT NUMBER OF
  INTERNET ACCESS CUSTOMERS IN OUR MARKETS.

     As we enter the high-speed Internet access business, we will be forced to
compete with numerous service providers, including the following:

     - other ISPs which have developed high-speed access capabilities such as
       DSL along with their existing services,

     - ILECs which are providing DSL-based services in addition to their
       existing wide area, metropolitan and local area networks,

     - interexchange carriers, which are expanding their networks to support
       high-speed local access, including DSL-based services and a full range of
       Internet services and applications,

     - cable modem service providers offering high-speed access services to
       consumers and businesses,

     - satellite and other fixed wireless data service providers, which have
       deployed or are developing broadband two-way data and voice services,

     - CLECs, which are offering high-speed data and other services, and

     - 3G wireless providers, which are expected to offer broadband mobile
       wireless services and capabilities.

     Many of our competitors are well-established and have larger and better
developed networks and systems, longer-standing relationships with customers and
suppliers, greater name recognition and significantly greater financial,
technical and marketing resources than we have. Many of these companies can
subsidize competing services with revenues from other services and have ready
access to capital markets. As competition increases in the high-speed Internet
access market, we anticipate intensified downward pricing pressure for our
services. If we are unable to compete effectively it will adversely affect our
ability to successfully implement our business strategy.

                                        21
<PAGE>

  WE CANNOT PREDICT WHETHER WE WILL BE SUCCESSFUL IN IMPLEMENTING OUR LONG-TERM
  BUSINESS STRATEGY BECAUSE IT INCLUDES OPERATIONS THAT HAVE NOT BEEN WIDELY
  DEPLOYED ON A COMMERCIAL BASIS. OUR FAILURE TO ACHIEVE OR SUSTAIN MARKET
  ACCEPTANCE COULD IMPAIR OUR ABILITY TO ACHIEVE PROFITABILITY.

     Our primary business strategy of providing broadband wireless services over
MMDS spectrum has not been widely deployed on a commercial basis. The success of
our long-term business strategy depends on our ability to develop and market our
high-speed Internet access service at profitable rates. We will face a number of
difficulties and uncertainties generally associated with new businesses, such
as:

     - lack of consumer acceptance,

     - difficulty in obtaining financing,

     - competition from providers using more traditional and commercially proven
       sources for these services,

     - advances in competing technologies, and

     - changes in laws and regulations.

     We have launched commercial high-speed Internet access service in only two
of our existing markets, and we cannot assure you that businesses and consumers
will accept our service as a commercially viable alternative to other means of
Internet access. In addition, the bankruptcies of fixed wireless point-to-point
providers Advanced Radio Telecom Corporation, Teligent, Inc. and Winstar
Communications, Inc., may adversely affect demand for our fixed wireless
point-to-multipoint services.

     To date we have not commercially launched wireless local loop or voice over
IP services over our spectrum. We cannot assure you that a system can be
designed to deliver telephony services over our spectrum on a commercial basis
or, if such a system can be designed, that we will receive the requisite
regulatory approvals to offer these services or that we will be able to deploy
these services in a commercially successful manner or at all.

  WE ARE SUBJECT TO EXTENSIVE FEDERAL LAWS, RULES AND REGULATIONS. THE LAWS,
  RULES AND REGULATIONS TO WHICH WE ARE SUBJECT COULD CHANGE AT ANY TIME IN AN
  UNPREDICTABLE MANNER.

     Our continued ability to acquire, lease and maintain MDS, MMDS and ITFS
spectrum, which is vital to our operations, is subject to extensive regulation.
These regulations directly affect the breadth of services we are able to offer,
as well as the rates, terms and conditions of those services. We also are
affected indirectly by other governmental regulations on companies that offer
competing services. Regulations and their application are subject to continual
change as a result of new legislation, regulations adopted from time to time by
regulatory authorities and judicial interpretation of these laws and
regulations. We are not able to predict the extent to which any change in the
regulatory environment could affect our business. We cannot assure you that
changes in legislation, regulations and interpretations would not have a
significant adverse impact on our ability to implement our business strategy.

     Aside from the use of spectrum, the FCC has held that Internet access
services are "information services" not subject to FCC regulation. Nevertheless,
the FCC has held that the Internet dial-up traffic is interstate traffic subject
to FCC jurisdiction. While the U.S. Court of Appeals for the D.C. Circuit
reversed and remanded the FCC's holding regarding Internet dial-up traffic, the
FCC has reaffirmed the holding on appeal. The FCC's affirmation of its holding
currently is being appealed. There can, therefore, be no certainty that the
providing of Internet access services will continue to be free from FCC
regulation. Moreover, if we begin providing wireless telecommunications or voice
over IP services, we will be subject to FCC and state regulation of our
interstate and intrastate telecommunications services, respectively.

  CHANGES IN THE REGULATORY STATUS OF THE 2.5 GHZ BAND MAY ADVERSELY AFFECT
  CURRENT AND FUTURE FIXED WIRELESS OPERATIONS.

     The FCC recently issued an order to allow limited mobile wireless use of
the 2.5 GHz band, in which we hold many of our FCC licenses and spectrum leases.
Under the FCC's order, existing licensees in the 2.5 GHz

                                        22
<PAGE>

band can offer mobile wireless services in addition to previously authorized
fixed services. Although the FCC's order seeks to protect fixed wireless use
from any interference by mobile systems, there is no assurance that the addition
of mobile services to the 2.5 GHz band will not adversely affect the operation
of fixed wireless systems in this band. Furthermore, we will rely on spectrum
leases with third party license holders to deliver some of our fixed wireless
services. If competition for use of this spectrum band develops from mobile
providers, we may not be able to obtain renewals for these leases on favorable
or acceptable terms. Additionally, use of the 2.5 GHz band for mobile services
will require an extensive rulemaking proceeding at the FCC to address
interference issues with fixed services currently authorized in the band. The
failure to finalize interference rules in the 2.5 GHz band could delay, limit or
eliminate the launch of mobile services in this band.

  THE 2.1 GHZ BAND IS ONE OF SEVERAL FREQUENCY BANDS CURRENTLY BEING CONSIDERED
  AS A SOURCE OF ADDITIONAL SPECTRUM FOR 3G MOBILE SYSTEMS. WE COULD BE REQUIRED
  TO RELOCATE EXISTING AND FUTURE OPERATIONS IN THE 2.1 GHZ BAND TO ACCOMMODATE
  3G MOBILE SYSTEMS.

     Various government agencies, including the FCC, have developed a plan to
identify additional spectrum for 3G services that includes the 2.1 GHz band. We
currently use the 2.1 GHz band in our existing wireless networks, and the 2.1
GHz band is part of our plan for future networks. We could be required to
relocate current and future broadband wireless services to another frequency
band. We are not able to determine at this time the impact that relocation would
have on our operations; however, relocation of operations to another frequency
band could require new or additional equipment, raise operating costs, delay the
provision of service, or render service uneconomic in certain areas.

  WE DEPEND ON FCC-REGULATED LICENSES AND SPECTRUM LEASES. THE FAILURE TO
  MAINTAIN SPECTRUM RIGHTS IN VARIOUS MARKETS COULD ADVERSELY AFFECT OUR ABILITY
  TO TIMELY IMPLEMENT OUR BUSINESS STRATEGY.

     We depend upon licenses granted to us by the FCC and leases with other FCC
license holders for access to spectrum capacity necessary to operate our
Internet business. These licenses are subject to renewal as determined by the
FCC. FCC licenses also specify construction deadlines by which channel
transmissions must begin, which, if not met, would permit the FCC to revoke the
license. We cannot assure you that:

     - the FCC will renew our licenses as their initial terms expire,

     - our spectrum lessors will continue to hold valid licenses for their
       spectrum,

     - we will be able to renew our spectrum leases on terms acceptable to us,
       or

     - the FCC will grant requests for extensions of construction deadlines.

     The failure to maintain FCC licenses and spectrum leases will reduce the
spectrum available for our use. If we fail to maintain sufficient FCC licenses
or spectrum leases in markets where we operate or in which we intend to launch
two-way Internet access service, then the resulting reduction in spectrum
capacity could have a material adverse effect on our ability to:

     - serve our existing Internet access customer base,

     - serve increasing customer demand for high-speed Internet access service,
       and

     - add services such as voice over IP or wireless telecommunications
       services.

     We cannot assure you that we will be able to obtain replacement spectrum or
other acceptable alternatives in a market if we lose an FCC license or spectrum
lease in that market.

                                        23

  OUR BROADBAND WIRELESS SYSTEMS WILL REQUIRE APPROVAL FROM THE FCC. ALTHOUGH WE
  HAVE RECEIVED FCC APPROVAL FOR OVER 95% OF THE APPLICATIONS WE FILED IN THE
  FCC'S INITIAL FILING WINDOW IN AUGUST 2000, WE WILL BE REQUIRED TO OBTAIN
  APPROVAL FOR ANY NEW APPLICATIONS AND ANY MODIFICATIONS TO OUR INITIAL
  APPLICATIONS. IF WE DO NOT OBTAIN REQUISITE APPROVALS FOR NEW APPLICATIONS OR
  MODIFICATIONS TO EXISTING APPLICATIONS IN A PARTICULAR MARKET, THEN WE MAY NOT
  BE ABLE TO OPERATE IN THAT MARKET.

     In August 2000, we filed over 400 applications with the FCC to receive
authorization for two-way broadband wireless operations in 70 markets. We have
received approval for over 95% of these applications, representing 90% of these
markets. We will be required to obtain additional approval for any new
applications and any modifications to our initial applications that we desire to
file to supplement spectrum capacity or modify a network design. New
applications and modifications to existing applications will be necessary for
deployment of a next generation technology platform. These applications must
meet FCC interference protection rules or contain the consent of other MDS, MMDS
and ITFS licensees in these markets and adjacent markets. We cannot assure you
that:

     - applications for new spectrum capacity or network modifications will not
       be preempted or otherwise limited by previously or concurrently filed
       applications of other operators, or

     - we will be able to obtain the necessary cooperation and consents from
       channel licensees in our markets or adjacent markets to enable us to
       optimize our network designs.

     If we do not receive the required consents for additional spectrum capacity
in a particular market, or we are not able to modify a network design, we may be
unable to operate service in that market in a cost-effective manner.

  OUR BASIC TRADING AREA, OR "BTA," AUTHORIZATIONS ARE SUBJECT TO FORFEITURE IF
  WE DEFAULT ON OUR PURCHASE PRICE PAYMENTS OR FAIL TO MEET CERTAIN SERVICE
  REQUIREMENTS. THE COSTS OF THE BUILD-OUT TO SATISFY OUR BTA SERVICE
  REQUIREMENTS COULD BE MATERIAL.

     We acquired authorizations for 93 BTAs in August 1996 at a total cost of
approximately $19.8 million. As of March 31, 2002, $10.1 million in principal
amount of this debt remained payable quarterly through August 2006. Each BTA is
subject to an individual installment note. If we fail to make one or more
scheduled installment payments on a BTA note after any applicable grace period,
that BTA authorization may be forfeited to the FCC.

     To retain a BTA authorization, we must provide a required level of service
in the BTA by August 2003. We will satisfy the service requirement for a BTA if
we construct MDS and MMDS stations capable of providing a signal to at least
two-thirds of the BTA population outside of the service areas of other MDS and
MMDS operators within our BTAs. If we fail to meet this requirement, or the FCC
does not waive, extend or otherwise modify the build-out requirement, then the
BTA authorization for the portion of the BTA that is not capable of being served
may be subject to forfeiture. Constructing MDS and MMDS channels capable of
providing service to the required population in unconstructed BTAs could require
substantial capital expenditures.

  CONVERSION OF OUR EXISTING WIRELESS CABLE SUBSCRIBERS WILL REQUIRE US TO
  MARKET, SELL AND INSTALL DIRECTV PROGRAMMING SERVICES TO EXISTING SUBSCRIBERS
  WHO CHOOSE TO ACCEPT THE CONVERSION OFFER. WE DO NOT EXPECT OUR EXISTING
  WIRELESS CABLE SUBSCRIBER BASE TO GENERATE MATERIAL REVENUES OR CASH FLOWS FOR
  THE COMPANY BEYOND MARCH 2003.

     Our sales agency agreements with DIRECTV and Pegasus require us to market,
sell and install DIRECTV programming packages to our existing wireless cable
subscribers, except for approximately 6,000 subscribers in Central Texas, to
whom Time Warner Cable has agreed to market, sell and install a conversion
offer. The failure of the Company or Time Warner Cable to effectively market,
sell or install conversion offers, or poor subscriber response to the conversion
program, will reduce the amounts payable by DIRECTV, Pegasus and Time Warner
Cable to us for converted subscribers. Except for a nominal residual royalty and
recognition of deferred revenue related to cash received at the time of
conversion, we do not expect our

                                        24
<PAGE>

existing wireless cable subscriber base to generate material revenues or cash
flows for the Company beyond March 2003. Although we intend to reduce
expenditures associated with our wireless cable business, ongoing costs of
maintaining our strategic FCC spectrum licenses and leases, as well as other
corporate overhead, will exceed revenues as we implement the conversion program.

  WE DEPEND ON KEY PERSONNEL. IF WE LOSE OUR CHIEF EXECUTIVE OFFICER, OUR
  ABILITY TO CARRY OUT OUR LONG-TERM BUSINESS STRATEGY COULD BE ADVERSELY
  AFFECTED.

     Our future success largely depends on the expertise of Carroll D. McHenry,
our Chief Executive Officer, President and Chairman of the Board, and other
members of senior management. We have employment agreements with Mr. McHenry and
other members of senior management, but do not maintain a key person life
insurance policy on the life of Mr. McHenry or other members of senior
management.

  BUILDING AND TOWER OWNERS CONTROL ACCESS TO CERTAIN STRATEGIC ANTENNA SITES.

     We will be required to obtain rights from building and tower owners to
install our antennas and other equipment to provide service to our customers. We
cannot assure you that we will be able to obtain, at costs or on terms
acceptable to us, the rights necessary to expand our services as planned.

  OUR INDUSTRY IS SUBJECT TO RAPID TECHNOLOGY CHANGES.

     The high-speed Internet access industry is subject to rapid technological
change, frequent new service introductions and evolving industry standards. We
believe that our future success will depend largely on our ability to anticipate
or adapt to these changes and to offer, on a timely basis, services that meet
evolving standards. We cannot predict the extent to which competitors using
existing or currently undeployed methods of delivery of Internet access services
will compete with our services. We cannot assure you that:

     - existing, proposed or undeveloped technologies will not render our
       broadband wireless systems less profitable or less viable,

     - we will have the resources to acquire new technologies or to introduce
       new services that could compete with future technologies, or

     - we will be successful in responding to technological changes in a timely
       and cost effective manner.

  WE MAY BE LIABLE FOR INFORMATION SENT THROUGH OUR NETWORK.

     The law relating to the liability of Internet access providers for
information carried on, stored on or disseminated through their network is
unsettled. Several private lawsuits seeking to impose liability upon Internet
access providers currently are pending. In addition, legislation has been
enacted and new legislation has been proposed that imposes liability for the
transmission of or prohibits the transmission of certain types of information on
the Internet, including sexually explicit and gambling information. While no one
has ever asserted a claim against us relating to this issue, someone may assert
a claim of that type in the future and may be successful in imposing liability
on us. Although we carry Internet liability insurance, it may not be adequate to
compensate claimants or may not cover us if we become liable for information
carried on or disseminated through our networks.

  OUR FAILURE TO FILE THIS ANNUAL REPORT ON FORM 10-K ON OR BEFORE THE APRIL 16,
  2002, DUE DATE SUBJECTS US TO DELISTING PROCEEDINGS UNDER THE RULES OF THE
  NASDAQ STOCK MARKET. IF OUR SHARES ARE DELISTED, OUR STOCKHOLDERS MAY
  EXPERIENCE SUBSTANTIALLY DECREASED LIQUIDITY IN THEIR SHARES, THE MARKET PRICE
  OF OUR STOCK WOULD LIKELY DECLINE AND OUR ABILITY TO OBTAIN FINANCING MAY BE
  ADVERSELY AFFECTED.

     Our stock is traded on The Nasdaq Stock Market. For continued listing,
Nasdaq requires companies to file with Nasdaq all reports required to be filed
with the Securities and Exchange Commission on or before the date those filings
are required to be filed with the Securities and Exchange Commission. This
report was required to be filed with the Securities and Exchange Commission on
April 16, 2002.

                                        25
<PAGE>

     We received a letter from The Nasdaq Stock Market notifying us that, as a
result of our failure to timely file this Annual Report on Form 10-K, our common
stock would be delisted from The Nasdaq Stock Market at the opening of business
on April 29, 2002, unless we requested a hearing in accordance with the Nasdaq
rules. We timely requested a hearing regarding the delisting of our common
stock, and a hearing has been set for May 23, 2002. We filed this report on Form
10-K on May 8, 2002, and believe that the filing of this report will eliminate
the need for the hearing and result in the continued listing of our common stock
on The Nasdaq Stock Market. However, we can make no assurances that Nasdaq will
not require a hearing or that, if a hearing is conducted, we will receive a
favorable determination for the continued listing of our common stock. If The
Nasdaq Stock Market were to delist the Company's common stock, our stockholders
would find it more difficult to dispose of their shares or obtain accurate
quotations as to their market value, and the market price of our stock would
likely decline. The failure of our stock to be listed on The Nasdaq Stock Market
also may adversely affect our ability to raise capital through the issuance of
securities or otherwise obtain financing.

  WE HAVE A LARGE PORTION OF OUR COMMON STOCK HELD BY A SMALL NUMBER OF OUR
  STOCKHOLDERS. THIS CONCENTRATION OF OWNERSHIP CAN AFFECT STOCKHOLDER VOTES AND
  CAUSE OUR STOCK PRICE TO BE VOLATILE IN THE PUBLIC TRADING MARKET.

     A large portion of our common stock is held by a small number of
stockholders. As a result, these stockholders are able to influence the outcome
of stockholder votes on various matters, including the election of directors and
extraordinary corporate transactions including business combinations. In
addition, the occurrence of sales of a large number of shares of our common
stock, or the perception that these sales could occur, may affect our stock
price and could impair our ability to obtain capital through an offering of
equity securities. Furthermore, the current ratios of ownership of our common
stock reduces the public float and liquidity of our common stock which can in
turn affect the market price of our common stock.

ITEM 2.  PROPERTIES

     We currently lease approximately 21,000 square feet of office space for our
executive offices in Carrollton, Texas. We also lease approximately 9,600 square
feet of space for telemarketing, customer care operations and training
facilities in Denison, Texas. We believe that the facilities described above are
leased at fair market value and are adequate for the foreseeable future.

     The principal physical assets of our operating systems consist of satellite
signal reception equipment, radio transmitters and transmission antennas and
customer premises equipment. We lease space or have options to lease space for
our broadband wireless Internet operations on about 100 communications towers.
The leases and options have terms from one to 15 years.

ITEM 3.  LEGAL PROCEEDINGS

     Securities Litigation.  Nucentrix and certain of our former officers and
directors were co-defendants in a stockholder action originally filed in
February 1998 in the United States District Court for the Northern District of
Texas, styled Coates, et al. v. Heartland Wireless Communications, Inc., et
al.(3-98-CV-0452-D). The Coates action involved federal securities laws claims
brought by two former stockholders of Heartland against Heartland and six former
officers and/or directors. In June 2000, the court dismissed the plaintiffs'
complaint with prejudice. The plaintiffs appealed the dismissal to the U.S.
Court of Appeals for the Fifth Circuit. In addition, three of our former
officers and directors were co-defendants in a purported class action lawsuit
originally filed in July 1998 in State District Court in Kleburg County, Texas,
styled Thompson, et al. v. David E. Webb, et al. (98-371-D). Plaintiffs in the
Thompson action alleged state securities laws violations, misrepresentation and
civil conspiracy claims.

     In 2001, the parties in the Coates and Thompson lawsuits executed
settlement agreements for the respective lawsuits. In January 2002, the court in
Thompson approved the settlement and entered a Final Judgment and Order of
Dismissal with prejudice in this matter. In March 2002, the Court of Appeals in
Coates dismissed the appeal pursuant to the settlement agreement entered into in
that lawsuit. All amounts payable by the defendants in the settlement of both
the Coates and Thompson lawsuits will be covered by the

                                        26
<PAGE>

proceeds from the Company's primary directors and officers liability insurance
policy. Accordingly, this settlement will not have a material adverse effect on
the consolidated financial condition, results of operations or cash flows of the
Company.

     Other Litigation.  Nucentrix and certain officers and directors of
Nucentrix are parties to several purported class action lawsuits relating to
administrative late fees, alleged breach of various consumer lease and credit
laws and alleged breach of Federal notice and privacy statutes. All of these
lawsuits were filed by the same plaintiff's attorney in various state and
federal courts in Texas, as follows:

     - Garcia, et al. v. Heartland Wireless Communications, Inc. d/b/a Heartland
       Cable Television (98-60898-1), filed in May 1998 and pending in the 79th
       Judicial District Court in Brooks County, Texas (dismissed and appealed),

     - John Nolen, Jr., et al. v. Nucentrix Broadband Networks, Inc.
       (DC-00-155), filed in May 2000 and pending in the 229th Judicial District
       Court in Duval County, Texas,

     - Nolen, et al. v. Nucentrix Broadband Networks, Inc., et al.(L-00CV134),
       filed in October 2000 in U.S. District Court for the Southern District of
       Texas, Laredo Division (dismissed and appealed),

     - Perez, et al. v. Nucentrix Broadband Networks, Inc. (01-141-D), filed in
       March 2001 and pending in the 105th Judicial District Court in Kleberg
       County, Texas,

     - Garcia v. Heartland Wireless Communications, Inc. (01-04-10449CV), filed
       in April 2001 in the 79th Judicial District Court in Brooks County, Texas
       (dismissed and appealed),

     - Torres v. Nucentrix Broadband Networks, Inc. (01-61022-1), filed in
       September 2001 and pending in County Court at Law No. 1 in Nueces County,
       Texas,

     - Santellana v. Nucentrix Broadband Networks, Inc. (S-01-6109-CV-B), filed
       in November 2001 in the 156th Judicial District Court in San Patricio
       County, Texas (dismissed),

     - Ysasi and Garcia v. Nucentrix Broadband Networks, Inc., DIRECTV, Inc., et
       al. (C-02-001), filed in January 2002 in U.S. District Court for the
       Southern District of Texas, Corpus Christi Division (dismissed), and

     - Santellana v. Nucentrix Broadband Networks, Inc. and DIRECTV, Inc.
       (C-02-079), filed in February 2002 and pending in U.S. District Court for
       the Southern District of Texas, Corpus Christi Division.

     These lawsuits generally allege that administrative late fees charged by
Nucentrix are unenforceable and/or usurious. The lawsuits generally seek to
certify a class to represent all persons who have entered into wireless cable
service agreements with Nucentrix or who have paid an administrative late fee to
Nucentrix, and seek a declaration that any contractual provisions for
Nucentrix's administrative late fees are usurious and/or unenforceable as a
penalty, money damages, interest, attorneys' fees, and costs.

     In addition, the Nolen lawsuit filed in the Southern District of Texas
alleges violation of the federal Racketeering Influenced and Corrupt
Organizations Act ("RICO"). The Nolen action alleges that Nucentrix and other
defendants together caused the collection of an unlawful debt comprised of a
service fee for subscription television services and an administrative late fee,
in violation of RICO. The plaintiff in Nolen seeks disgorgement and payment of
unspecified restitution to members of the purported class, as well as treble
damages, attorneys' fees, interest and costs.

     Furthermore, the Ysasi and Garcia action and first Santellana lawsuit noted
above allege breach of several federal and state statutes relating to consumer
lease and credit transactions, including the Consumer Leasing Act, Truth in
Lending Act, Magnuson-Moss Warranty Act, and the Texas Business and Commerce
Code. The plaintiffs in these matters seek statutory, compensatory and punitive
damages, as well as attorneys' fees, costs and interest. Finally, the second
Santellana lawsuit noted above alleges breach of notice and privacy provisions
of the Cable Act by Nucentrix and DIRECTV.

     We believe the above actions to be without merit and intend to vigorously
defend them. The initial Garcia lawsuit and the second Nolen lawsuit noted above
have been dismissed by the U.S. Bankruptcy Court for the
                                        27
<PAGE>

District of Delaware and the U.S. District Court for the Southern District of
Texas, respectively. The plaintiffs have appealed these decisions. In March
2002, the courts in the second Garcia lawsuit and in the first Santellana
lawsuit granted our Motions to Compel Arbitration and dismissed these lawsuits.
The plaintiff in Garcia has filed a notice of appeal. In April 2002, the U.S.
District Court for the Southern District of Texas dismissed the federal claims
in the Ysasi and Garcia lawsuit with prejudice and dismissed the state law
claims (which were supplemental to the federal claims) without prejudice. In
addition, Texas courts in Nueces and San Patricio counties have dismissed two
similar late fee lawsuits filed by the same plaintiff's attorney against the
Company, with no appeal. While it is not feasible to predict or determine the
final outcome of these proceedings or to estimate the amounts or potential range
of loss with respect to these matters, and while management does not expect such
an adverse outcome, management believes that an adverse outcome in one or more
of these proceedings could have a material adverse effect on our financial
condition, results of operations or cash flows.

     State Court Action.  In December 2000, several former stockholders of
Heartland filed a lawsuit against certain of our current and former directors
and officers, and former holders of our senior notes (several of whom currently
own more than five percent of our outstanding common stock), styled Hunt Capital
Group, L.L.C., et al., v. Carroll D. McHenry, et al., Case No. OJ-2000-534 in
the District Court for Bryan County, Oklahoma. The plaintiffs allege that the
defendants purposely undervalued our enterprise value as part of the Plan
confirmation process in order to extinguish all prepetition equity holders'
interests. The plaintiffs seek unspecified damages in excess of $10,000 on
behalf of all prepetition stockholders of Heartland, under theories of fraud,
negligent misrepresentation, unjust enrichment, breach of fiduciary duty, and
constructive trust.

     In February 2001, certain of the defendants removed this lawsuit to the
U.S. District Court for the Eastern District of Oklahoma, which was subsequently
assigned Civil Action No. 01-095-S. The defendants concurrently sought transfer
of venue from the Eastern District of Oklahoma to the U.S. District Court for
the District of Delaware and, in April 2001, the U.S. District Court for the
Eastern District of Oklahoma granted the defendants' motion to transfer venue to
U.S. District Court for the District of Delaware. In addition, in February 2001
we filed, in the U.S. Bankruptcy Court for the District of Delaware, an
Emergency Motion to Enforce Plan of Reorganization and Confirmation Order,
seeking to enjoin and prevent the state court action from proceeding as a
violation of the terms of our confirmed Plan. In June 2001, the Bankruptcy Court
granted our motion and ordered that the plaintiffs dismiss the lawsuit with
prejudice. Plaintiffs have appealed this decision to the U.S. District Court for
the District of Delaware. The appeal is pending.

     We may have certain indemnity obligations to the director and officer
defendants in the Hunt Capital matter. We believe the allegations to be without
merit and intend to vigorously defend this action on behalf of the director and
officer defendants.

     Other.  Nucentrix is involved in routine legal and regulatory proceedings
incident to our business. We do not believe that any other pending legal or
regulatory matter will have a material adverse effect on our consolidated
financial condition, results of operations or cash flows.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were no matters submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of the fiscal
year ended December 31, 2001.

     Nucentrix's Annual Meeting of Stockholders for 2002 is scheduled for June
28, 2002. This date has changed by more than 30 days from the May 10 date of
Nucentrix's 2001 Annual Meeting of Stockholders. Therefore, as required by the
Securities Exchange Act of 1934, the dates originally disclosed in Nucentrix's
proxy statement for the 2001 annual meeting by which stockholder proposals for
the 2002 annual meeting must be delivered to Nucentrix for purposes of Rule
14a-8 and Rule 14a-4(c) of the Securities Exchange Act have been changed to May
26, 2002, as described below.

     To qualify for inclusion in the proxy statement and form of proxy relating
to the 2002 annual meeting of stockholders, under Rule 14a-8 of the Securities
Exchange Act a proposal intended by a stockholder for presentation at that
meeting must be received by Nucentrix at its principal executive offices on or
before

                                        28
<PAGE>

May 26, 2002. Under Rule 14a-4(c) of the Securities Exchange Act, the Board of
Directors may exercise discretionary voting authority under proxies solicited by
it on any matter properly presented by a stockholder at Nucentrix's 2002 Annual
Meeting that the stockholder does not seek to have included in Nucentrix's proxy
statement under Rule 14a-8 of the Securities Exchange Act if, except as
described in the following sentence, the proxy statement discloses the nature of
the matter and how the Board of Directors intends to exercise its discretion to
vote on such matter, unless Nucentrix is notified of the proposal on or before
May 26, 2002, and the stockholder satisfies the other requirements of Rule
14a-4(c)(2). If Nucentrix first receives notice of such matter after May 26,
2002, the Board of Directors may exercise discretionary voting authority on any
matter as permitted under Rule 14a-(c)(2), without including any discussion of
the matter in the proxy statement for the 2002 annual meeting. Nucentrix
reserves the right to reject, rule out of order or take other appropriate action
on any proposal that does not comply with the requirements described above and
other applicable requirements.

     We received a letter from The Nasdaq Stock Market notifying us that, as a
result of our failure to timely file this Annual Report on Form 10-K, our common
stock would be delisted from The Nasdaq Stock Market at the opening of business
on April 29, 2002, unless we requested a hearing in accordance with the Nasdaq
rules. We timely requested a hearing regarding the delisting of our common
stock, and a hearing has been set for May 23, 2002. We filed this report on Form
10-K on May 8, 2002, and believe that the filing of this report will eliminate
the need for the hearing and result in the continued listing of our common stock
on The Nasdaq Stock Market. However, we can make no assurances that Nasdaq will
not require a hearing or that, if a hearing is conducted, we will receive a
favorable determination for the continued listing of our common stock.

     The number of record holders of common stock as of March 31, 2002, was 18.

DIVIDENDS

     We have not paid any cash dividends on our common stock, and do not intend
to pay cash dividends in the foreseeable future. Our Board of Directors may
reexamine our dividend policy from time to time. However, if we raise capital in
the future through financings obtained from outside sources, the terms of these
financings may restrict or prohibit us from paying any dividends on our common
stock.

ITEM 6.  SELECTED FINANCIAL DATA

     The following table presents summary historical financial and other data
for Nucentrix. As a result of the application of Fresh Start Reporting,
financial information as of December 31, 2001, 2000 and 1999, and for the years
ended December 31, 2001 and 2000, and the period from the Effective Date to
December 31, 1999 (the "Successor Period"), is presented on a different basis
than the financial information as of December 31, 1998 and 1997, and for each of
the years in the two year period ended December 31, 1998, and for the period
from January 1, 1999, to the Effective Date (collectively, the "Predecessor
Period"). See Item 1, "Business -- Reorganization." The selected historical
financial data presented below as of and for each of the years in the five year
period ended December 31, 2001, is derived from the audited consolidated
financial statements of Nucentrix. Historically, we have used our spectrum
primarily to deliver wireless cable services, and we have announced our intent
to convert this subscriber base and clear our spectrum to provide broadband
wireless Internet, data and other services. Therefore, our historical results
are not necessarily indicative of our future results as we pursue our business
strategy as described in Item 1, "Business -- Overview." You should read the
financial data below together with Item 7, "Management's Discussion and Analysis
of Financial Condition and Results of Operations," and with Nucentrix's
consolidated financial statements, including the notes thereto, included
elsewhere in this report.

(1) We changed the useful lives for depreciating the nonrecoverable portion of
    subscriber installation costs in 1997.

(2) In the fourth quarter of 2001, in accordance with Statement of Financial
    Accounting Standards ("SFAS") No. 121, we wrote down systems and equipment,
    and license and leased license investments (spectrum licenses and leases) to
    estimated fair value, which resulted in a non-cash impairment charge of
    $14.1 million. See Item 7, "MD&A -- Results of Operations for the Three
    Years Ended December 31, 2001 -- Impairment of Long-Lived Assets," and note
    2 to the consolidated financial statements. In the second and third quarters
    of 1998, we wrote down license and leased license investments, systems and
    equipment and other long-lived assets to estimated fair value, which
    resulted in a non-cash impairment charge of $105.8 million.

(3) We filed a voluntary petition for reorganization under Chapter 11 of the
    U.S. Bankruptcy Code on December 4, 1998. Our Plan was confirmed on March
    15, 1999, and became effective on April 1, 1999. Accordingly, we have
    reclassified our prior senior and subordinated notes, which were subject to
    compromise in the reorganization, to "Liabilities Subject to Compromise" at
    December 31, 1998. Expenses related to our reorganization, such as
    professional fees and administrative expenses, were classified as
    "Reorganization costs." See note 1(c) to the consolidated financial
    statements.

(4) Loss per basic and dilutive common share for each period presented has been
    calculated using the provisions of SFAS No. 128, "Earnings per Share," which
    is effective for periods ending after December 15, 1997, and requires
    restatement of all prior period loss per share data. Earnings per share
    information has not been presented for the Predecessor Period because
    Nucentrix was recapitalized on the Effective Date, in connection with the
    Plan, and accordingly, per share amounts are not comparable between the
    Predecessor Period and the Successor Period. See note 1(l) to the
    consolidated financial statements.

(5) "EBITDA," or earnings before interest, taxes, depreciation, amortization,
    and non-recurring items, is widely used by analysts, investors and other
    interested parties in the Internet, cable television and telecommunications
    industries. EBITDA is also a widely accepted financial indicator of a
    company's ability to incur and service indebtedness. EBITDA is not a
    financial measure determined by generally accepted accounting principles and
    should not be considered as an alternative to net income as a measure of
    operating results or to cash flows as a measure of funds available for
    discretionary or other liquidity purposes. EBITDA may not be comparably
    calculated from one company to another.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

     General.  We provide broadband wireless Internet and wireless subscription
television services using up to approximately 200 MHz of radio spectrum licensed
by the FCC in the 2.1 GHz and 2.5 GHz bands, primarily in medium and small
markets across Texas, Oklahoma and the Midwestern United States. We own the BTA
authorization, or otherwise license or lease MDS, MMDS and ITFS spectrum, in 95
markets covering an estimated 9 million total households, including two markets
covering an estimated 400,000 total households for which we have entered into a
definitive agreement or letter of intent to acquire. On average, we own or lease
151 MHz of spectrum per market. Our long-term business strategy is to provide
fixed, portable and, ultimately, mobile broadband Internet access and other
information services using our high-capacity MMDS radio spectrum in medium and
small markets. See Item 1, "Business -- Overview" in this report.

     Historically, we have used our spectrum to provide wireless subscription
television services, commonly referred to as "wireless cable." We presently have
wireless cable transmission facilities constructed and operating in 57 markets
in eight states. At March 31, 2002, we had approximately 75,600 wireless cable
customers, including approximately 70,600 customers who subscribed only to
programming service provided over our MMDS spectrum, and 5,000 "combo"
subscribers who subscribed to both our MMDS programming service and to DIRECTV
programming service sold by us. In addition, at March 31, 2002, there were
approximately 23,900 customers who received only DIRECTV programming sold by us.
In March 2002, as part of our long-term plan to focus on the use of our spectrum
for broadband Internet and other advanced wireless services, we announced the
signing of agreements with DIRECTV, Pegasus and Time Warner Cable to convert
substantially all of our wireless cable subscribers to programming provided by
these entities. See Item 1, "Business -- Conversion of Wireless Cable Business"
in this report.

     Reorganization.  On April 1, 1999, the Effective Date, we consummated our
Plan to, among other things, exchange approximately $325 million of senior and
subordinated debt and accrued interest for common stock. As a result of the
application of Fresh Start Reporting, financial information in the consolidated
financial statements as of December 31, 2001, 2000 and 1999, and for the years
ended December 31, 2001 and 2000, and the period from the Effective Date to
December 31, 1999 (the "Successor Period"), is presented on a different basis
than the financial information for the period January 1, 1999, to the Effective
Date (the "Predecessor Period"). Accordingly, such information is not
comparable. The Predecessor Period includes operations through March 31, 1999,
plus the gain on debt forgiveness recognized on the Effective Date. The
Successor Period includes operations from the Effective Date through December
31, 2001. See Item 1, "Business -- Reorganization."

     Revenues.  Our revenues currently consist primarily of monthly fees paid by
wireless cable subscribers for basic programming, premium programming, equipment
rental, and other miscellaneous fees, and revenues from our agency relationship
with DIRECTV (which will include revenues from DIRECTV and others in 2002 from
the conversion program discussed in Item 1 of this report). Revenues also
include fees generated from Internet operations in Austin and Sherman-Denison,
Texas. Unless the context requires otherwise, all references to "subscribers" or
"systems" are to our wireless cable subscribers and systems because revenues and
subscribers from our Internet business were immaterial in 2001 (approximately 1%
of consolidated revenues).

     Subscription revenues from wireless cable subscribers and continuing
monthly service fees from DIRECTV for each DIRECTV customer generated are
recognized as service is provided. If the Company does not meet minimum
subscriber benchmarks each year, the DIRECTV continuing monthly service fee will
be reduced.

     Effective January 1, 2001, wireless cable and DIRECTV installation revenue,
and revenue received from our agency relationship with DIRECTV (except for
continuing monthly service fees, which are recognized as received), is
recognized to the extent of direct selling costs incurred, and the remainder is
deferred and amortized to income over the expected subscriber relationship
period of three years. A chargeback reserve is recorded for all DIRECTV
contingencies. Prior to 2001, wireless cable installation revenue was offset
against

                                        32
<PAGE>

the nonrecoverable portion of installation costs, with the excess cost
capitalized and amortized to depreciation expense over the expected subscriber
relationship period of three years. Prior to 2001, DIRECTV installation revenue
(cash received directly from the customer in conjunction with the sale) was
offset against direct incremental costs, with the resulting amount recorded as a
net asset. This asset, referred to as "subscriber acquisition costs," was
amortized as a component of Selling, General and Administrative expense in
proportion to the revenues projected to be generated over the expected
subscriber relationship period. Revenue from our agency relationship with
DIRECTV (other than monthly service fees) was recognized as the contingencies
related to each revenue component were resolved. A chargeback reserve was not
recorded for canceled subscribers. The Company revised the application of its
SFAS No. 51 accounting for wireless cable installation and DIRECTV revenues
prospectively, effective January 1, 2001, as discussed above. See
"MD&A -- Revised Application of Accounting Policy and Restatement of 2001
Quarterly Results."

     System Operations Expenses.  System operations expenses include channel
lease payments, wireless cable programming costs, labor, and overhead, and costs
related to service calls and disconnects, transmitter site and tower rentals,
and certain repairs and maintenance expenditures. Programming costs, with the
exception of minimum payments, channel lease payments, and repairs and
maintenance, are variable expenses based on the number of subscribers.

     Selling, General and Administrative ("SG&A") Expenses.  SG&A expenses
include office and administrative costs of operating our 57 wireless cable
markets and our two Internet markets, as well as sales and marketing and bad
debt expenses related to these operations and corporate costs directly and
indirectly allocated to these operations. In addition, the direct incremental
costs incurred in generating a customer relationship with DIRECTV, comprised of
material, equipment and labor, are recorded as an asset. This asset, referred to
as "subscriber acquisition costs," is amortized as a component of SG&A expense
over the expected subscriber relationship period of three years. Prior to 2001,
the direct incremental cost was offset by DIRECTV installation revenue, with
only the resulting excess cost recorded as subscriber acquisition costs and
amortized as a component of SG&A expense in proportion to revenues projected to
be generated over the expected subscriber relationship period. The Company
revised the application of its SFAS No. 51 accounting for DIRECTV installation
revenue prospectively, effective January 1, 2001, as discussed above. See
"MD&A -- Revised Application of Accounting Policy and Restatements of 2001
Quarterly Results."

     Depreciation and Amortization Expense.  Depreciation and amortization
expense includes depreciation of systems and equipment and capitalized
installation costs, and amortization of license and leased license investment.
Our policy is to capitalize the direct costs of wireless cable installations.
These direct costs include reception materials and equipment on subscriber
premises and installation labor. These direct costs are capitalized as systems
and equipment in the accompanying consolidated balance sheets, and are amortized
over the useful life of the asset (currently five years) for the recoverable
portion and the estimated average subscription term (currently three years) for
the nonrecoverable portion of such costs. The nonrecoverable portion of the cost
of a wireless cable installation becomes fully depreciated upon disconnection of
the subscriber. Prior to 2001, the Company capitalized only the excess of
nonrecoverable costs of wireless cable installations over installation revenue.
The Company revised the application of its SFAS No. 51 accounting for wireless
cable nonrecoverable installation costs prospectively, effective January 1,
2001, as discussed above. See "MD&A -- Revised Application of Accounting Policy
and Restatement of 2001 Quarterly Results."

     EBITDA.  EBITDA, or earnings before interest, taxes, depreciation,
amortization, and non-recurring items, is widely used by analysts, investors and
other interested parties in the Internet, cable television and telecommunication
industries. EBITDA is also widely accepted as a financial indicator of a
company's ability to incur and service indebtedness. EBITDA is not a financial
measure determined by generally accepted accounting principles and should not be
considered an alternative to net income as a measure of operating results or to
cash flows as a measure of funds available for discretionary or other liquidity
purposes. EBITDA may not be comparably calculated from one company to another.

RESULTS OF OPERATIONS FOR THE THREE YEARS ENDED DECEMBER 31, 2001

     The following table summarizes the operating results for the year ended
December 31, 2001, in comparison to the years ended December 31, 2000 and 1999,
combining the 1999 results for the 1999 Predecessor Period (January 1, 1999,
through the Effective Date) with the Successor Period (the Effective Date
through December 31, 1999). The most significant impact of the Plan was a
decrease in depreciation and amortization expense due to the write-down of
certain long-lived assets to estimated fair value, a decrease in interest
expense due to the extinguishment of certain liabilities subject to compromise,
and a one-time, non-recurring gain on extinguishment of liabilities subject to
compromise. Specific trends addressed within the discussion of operating results
will refer to the combined results as presented in this table, unless otherwise
noted:

</Table>

     Revenues.  Our revenues were $49.8 million in 2001, $61.0 million in 2000
and $70.5 million in 1999, representing a 18% decrease from 2000 to 2001 and a
13% decrease from 1999 to 2000. The average number of wireless cable subscribers
for the year ended December 31, 2001, was 94,000 compared to 121,000 and 145,000
for the years ended December 31, 2000 and 1999, respectively. In addition,
during the years ended December 31, 2001, 2000 and 1999, we had 23,000, 16,500
and 9,300 average subscribers, respectively, who received only DIRECTV
programming sold by us. Beginning in January 2000, we did not include these
customers in our reported wireless cable subscriber base but we do receive
certain agency revenue from DIRECTV related to these accounts, as well as
equipment lease payments from a portion of these customers. We also do not
include these customers or their related revenues in our calculation of
recurring average revenue per subscriber. Prior year calculations have been
revised to conform with this presentation.

     The decline in revenues from 1999 to 2001 was primarily due to fewer total
wireless cable subscribers resulting from:

     - decreased sales and marketing as we continued to shift our principal
       business focus from providing wireless cable service to testing and
       developing our broadband wireless IP-based services,

     - price increases for our wireless cable service in the first and third
       quarters of 2001 and fourth quarter of 1998, which resulted in increased
       disconnects by video subscribers in 2001 and 1999, respectively, and

     - the suspension, in seven markets in March 2000, of our offer of video
       programming provided solely over MMDS frequencies in anticipation of
       transitioning this spectrum to Internet services.

     In addition, in 2001 the Company adjusted the fair value of its liabilities
at Fresh Start by $2.5 million, and correspondingly reduced revenues that had
been deferred and recognized since Fresh Start. Also, in

                                        34
<PAGE>

connection with its revised application of SFAS No. 51 in 2001, the Company
established a $2.2 million chargeback reserve for canceled subscribers. These
two changes resulted in a reduction in total revenues in 2001 of $4.7 million.

     This decline was partially offset by a revision in policy for recognizing
wireless cable and DIRECTV installation revenue and revenue received from our
agency relationship with DIRECTV (except for continuing monthly service fees,
which are recognized as received). Prior to 2001, wireless cable installation
revenue was offset against the nonrecoverable portion of installation costs,
with the excess cost capitalized and amortized to depreciation expense over the
expected subscriber relationship period. Prior to 2001, DIRECTV installation
revenue (cash received directly from the customer in conjunction with the sale)
was offset against direct incremental costs, with the resulting amount recorded
as a net asset and amortized to SG&A in proportion to the revenues projected to
be generated over the expected subscriber relationship period. Beginning in
2001, these revenues are now recognized to the extent of direct selling costs
incurred, and the remainder is deferred and amortized to income over the
expected subscriber relationship period of three years. This resulted in $3.4
million of additional revenues in 2001.

     Average monthly recurring revenue per subscriber was $37.06, $35.44 and
$35.04 for the years ended December 31, 2001, 2000 and 1999, respectively. The
increase over these periods is due to overall higher priced packages being
purchased by our subscribers, including increased purchases of premium
programming and price increases for wireless cable services.

     We expect to convert our wireless cable subscriber base to satellite
programming provided by DIRECTV and Pegasus, and cable programming provided by
Time Warner Cable, by March 2003. Except for a nominal residual royalty and
recognition of deferred revenue related to cash received at the time of
conversion, we do not expect our existing wireless cable subscriber base to
continue to generate material revenues or cash flows for the Company beyond
March 2003. See Item 1, "Business -- Conversion of Wireless Cable Business" in
this report. We expect to recognize revenues associated with the conversion of
subscribers to DIRECTV and Pegasus to the extent of direct selling costs
incurred, and the remainder to be deferred and amortized to income over the
expected subscriber relationship period of three years. A chargeback reserve
will be recorded for all DIRECTV contingencies. We do not expect the decline in
revenues to be offset materially by an increase in revenues from our Internet
business in 2002, as it is unlikely that we will be able to validate the most
efficient technical platform for delivery of advanced wireless services early
enough in 2002 to then deploy and successfully operate this technology in our
markets.

     System Operations Expense.  System operations expenses were $25.7 in 2001,
$28.4 million in 2000 and $32.4 million in 1999. As a percentage of revenues,
system operations expenses were 52% in 2001, 47% in 2000 and 46% in 1999. The
decrease in system operations expense over the periods presented was primarily
due to lower service call expense and programming expense as a result of lower
subscriber count and a larger proportion of DIRECTV subscribers, which have
lower programming costs. System operations expense as a percent of revenue
increased in 2001 and 2000 due to higher costs under certain spectrum leases
that were renegotiated in preparation for providing two-way broadband wireless
services, and due to the fixed portion of technical labor in certain video
markets which has been reduced to minimum levels with the decline in
subscribers. We expect system operations expense to decrease further in 2002 as
we reduce technical and operational support in our wireless cable markets to
minimum levels and eliminate programming and service call costs. We will
continue to incur labor costs through 2002 and the first quarter of 2003 in
connection with the conversion of our wireless cable subscriber base. See Item
1, "Business -- Conversion of Wireless Cable Business" in this report.

     SG&A Expense.  SG&A expense was $25.5 million in 2001, $32.8 million in
2000 and $35.3 million in 1999. As a percent of revenues, SG&A expense was 51%
in 2001, 54% in 2000 and 50% in 1999. SG&A expense decreased annually from 1999
through 2001 due to savings from the consolidation of certain offices and
management in our wireless cable markets, lower bad debt expense due to improved
collections, lower wireless cable marketing expenses, and a reduction in
start-up and general and administrative costs, principally incurred in the first
quarter of 2001, related to our broadband wireless Internet business. The
reduction in overall SG&A from 1999 through 2001 was partially offset by
increased costs related to the development of

                                        35
<PAGE>

Internet access and other IP-based services and related infrastructure at the
end of 2000 and the beginning of 2001, the operation of our two operating
Internet markets in Austin and Sherman-Denison, Texas and allocable corporate
overhead. Internet SG&A decreased from 2000 to 2001, primarily due to a
reduction in force and related cost savings caused by a delay in availability of
a next generation technology platform. We expect overall SG&A expenses to
continue to decline in 2002 as wireless cable television field offices are
closed and related administrative costs are reduced.

     Depreciation and Amortization.  Depreciation and amortization expense was
$25.7 million in 2001, $27.3 million in 2000 and $25.3 million in 1999. The
increase in depreciation and amortization expense from 1999 to 2000 was
primarily due to a larger number of disconnected MMDS subscribers. When
subscribers are disconnected, the remaining balance of nonrecoverable equipment
related to the installation of that subscriber is written off to depreciation
expense. The decrease in depreciation and amortization expense from 2000 to 2001
is principally due to fewer disconnects in 2001 compared to 2000 and, to a
lesser extent, the sale of used equipment during 2000 and 2001. We expect
depreciation and amortization to increase in 2002 as wireless cable assets are
fully depreciated, and wireless cable market operations are closed upon
conversion of our wireless cable subscriber base as discussed above.

     Impairment of Long-Lived Assets.  In the fourth quarter of 2001, we
reviewed our systems and equipment, and license and leased license investment
assets (spectrum licenses and leases) for impairment in accordance with the
requirements of SFAS No. 121. Events and circumstances that we considered in our
review included (i) the expected conversion of substantially all of our wireless
cable subscribers to satellite and cable programming provided by other
companies, (ii) the need to continue evaluating the development of technology
for MMDS service which likely would delay deployment of new Internet markets
beyond 2002, and (iii) the uncertainties associated with raising capital
required to implement our long-term business plan.

     In determining whether an impairment was required for systems and
equipment, we examined the future cash flows expected to be generated from these
assets and the amount that we estimated could be realized for these assets in an
orderly disposition, if required. In analyzing our license and leased license
investment assets, we retained the services of a third party to provide a fair
market valuation. As a result, we determined that a non-cash impairment charge
of $14.1 million in 2001 was required to write down systems and equipment and
license and leased license investments to estimated fair value, as follows:

                                                              =============

     Although the third party market valuation of our aggregate license and
leased license investment assets was substantially in excess of our aggregate
carrying cost, as required by SFAS No. 121 we examined these assets on an
individual market basis and determined that the carrying value related to ten
markets should be written down in the total amount of $9.4 million.

     Our estimates of future gross revenues and operating cash flows, the
remaining estimated lives of long-lived assets, or both could be reduced in the
future due to changes in, among other things, technology, government regulation,
available financing, or competition. As a result, the carrying amounts of
long-lived assets could be reduced by additional amounts which would be material
to the Company's financial position and results of operations.

     Operating Loss.  We generated operating losses of $41.2 million ($27.1
million excluding the impairment of long-lived assets) in 2001, $27.5 million in
2000 and $22.4 million in 1999. The improvement in operating losses (excluding
the impairment of long-lived assets) from 2000 to 2001 resulted from lower
programming expense, decreased marketing costs and other SG&A savings discussed
above, and lower depreciation and amortization expense. The increased losses
from 1999 to 2000 were primarily due to lower wireless cable revenues,
additional expenditures related to testing and development of broadband wireless
services, and increased depreciation related to a larger number of disconnects
in 2000. Increased losses for 2000 were partially offset by lower programming
expense, savings from consolidation of certain offices and

                                        36
<PAGE>

management in our wireless cable markets, lower wireless cable marketing costs,
and lower bad debt expense. Compared to 2001, we expect operating loss in 2002
to decrease slightly.

     EBITDA.  EBITDA was a negative $1.4 million for the year ended December 31,
2001, a negative $202,000 for the year ended December 31, 2000 and a positive
$2.8 million for the year ended December 31, 1999. The decrease in EBITDA from
1999 to 2001 was primarily due to decreased wireless cable revenues resulting
from fewer subscribers as we continued to shift our principal focus to
developing our broadband wireless IP-based services, and from start-up and SG&A
costs related to our broadband wireless Internet operations. We expect EBITDA to
decrease materially from 2001 in 2002, as we convert wireless cable subscribers
and clear our spectrum for our broadband wireless Internet business.

     Interest Income.  Interest income was $984,000 in 2001, $2 million in 2000
and $1.6 million in 1999. The decrease in interest income from 2000 to 2001 was
due to higher earnings during 2000 on larger unrestricted cash balances. The
increase in interest income from 1999 to 2000 was due to higher rates earned in
2000 on larger unrestricted cash balances partly resulting from cash received on
the sale of our investment in Wireless One, Inc. ("Wireless One") during 2000.
Average interest rates were 4.8% in 2001, 6.3% in 2000, and 5.4% in 1999.

     Interest Expense.  Interest expense was $1.2 million in 2001, $1.4 million
in 2000 and $1.1 million in 1999. Interest expense decreased from 2000 to 2001
due to lower principal balances on our BTA debt and capital leases. Interest
expense increased slightly from 1999 to 2000 because of higher debt balances
related to capital lease obligations incurred in connection with the sale and
leaseback of 34 tower sites that were sold during the fourth quarter of 1999 and
the first nine months of 2000. Interest rates on our capital lease obligations
in 2001 were an average of 14.9%. The interest rate on other notes payable in
2001 was 9.5%.

     Other income (expense).  Other income was $589,000 during 2001, $4.8
million during 2000 and $485,000 during 1999. Other income in 2001 principally
includes the recognition of a deferred gain on the sale and leaseback of 34 of
our towers during 1999 and 2000 and a $100,000 gain from the sale of our equity
interest in a Mexican MMDS company. During the first and third quarters of 2000,
we received $3.8 million and $723,000, respectively, in exchange for our equity
interest in Wireless One. The entire amount was recognized as other income, as
our investment balance had been reduced to zero. Other income during 2000 also
included the recognition of the deferred gain on the tower sale and leaseback
described above. Other income in 1999 consists primarily of cash settlements
from certain litigation matters.

     Income Tax Benefit.  Federal income tax law related to reorganizations
generally requires that the amount of income from discharge of indebtedness that
occurs in connection with a Chapter 11 bankruptcy be used to reduce federal tax
attributes. Generally, the reduction is applied to reduce net operating loss
carryforwards, followed by other tax attributes including the basis of certain
assets and the tax basis of subsidiary stock ("Tax Attribute Reduction"). An
election exists to reduce the basis of depreciable assets first, which can be
favorable under certain circumstances. Management elected to apply the required
reduction first to tax basis in depreciable assets, and then to net operating
loss carryforwards. The amount of reduction in depreciable assets was
approximately $56 million. The amount of reduction in net operating loss
carryforwards was approximately $118 million, leaving approximately $222 million
in remaining net operating loss carryforwards. No income tax benefit was
recorded for the years ended December 31, 2001, 2000 and 1999.

     Reorganization Costs.  During the year ended December 31, 1999, we incurred
$3.3 million in expenses related to our reorganization under Chapter 11 of the
U.S. Bankruptcy Code. These costs were for financial and legal advisors,
accountants and administrative costs. There were no reorganization costs in 2000
or 2001.

     Gain on Debt Forgiveness.  In connection with our reorganization under
Chapter 11, on the April 1, 1999, Effective Date of our reorganization, we
recorded an extraordinary gain of approximately $173.8 million reflecting the
extinguishment of certain liabilities subject to compromise in exchange for
common stock and warrants. Upon consummation of our Plan on April 1, 1999, our
senior and convertible subordinated notes totaling approximately $318 million,
including the interest accrued thereon and associated unamortized discounts and
debt issuance costs, were canceled and exchanged for 10 million shares of
newly-issued common

                                        37
<PAGE>

stock and warrants to acquire 825,000 shares of common stock, with a combined
estimated fair value of $144.2 million as of the Effective Date. This
extraordinary gain is not taxable to us pursuant to Federal income tax law
because it arose in connection with our recapitalization under Chapter 11 of the
U.S. Bankruptcy Code. It does, however, result in a permanent Tax Attribute
Reduction.

     Net Loss.  We have recorded net losses since our inception. Our net loss
was $40.9 million in 2001 ($26.8 million excluding the impairment of long-lived
assets) and $22.1 million in 2000. Excluding the gain of $4.8 million in 2000
discussed below, net loss in 2000 was $26.9 million. Excluding the extraordinary
gain on debt forgiveness discussed above, we incurred a net loss of $7.6 million
for the period from January 1, 1999, to the Effective Date and a net loss of
$17.2 million for the period from the Effective Date to December 31, 1999. The
net loss from 1999 to 2001 was primarily impacted by the following:

     - lower wireless cable revenue and programming costs related to fewer
       subscribers,

     - the impact of revising the application of SFAS No. 51, in 2001

     - cost savings from consolidation of certain market offices and management,

     - decreased subscription television marketing expenses,

     - the impairment of long-lived assets in 2001,

     - a gain of $4.8 million during 2000 on the exchange of our equity interest
       in Wireless One and on the sale and leaseback of our towers, and

     - no reorganization costs in 2001 or 2000 compared to $3.3 million in 1999.

     Loss per share for the year ended December 31, 2001, was $3.95 per share,
compared to $2.17 in 2000 and $1.71 for the period from the Effective Date to
December 31, 1999. Earnings per share information has not been presented for the
Predecessor Period as Nucentrix was recapitalized on the Effective Date in
connection with our Plan and, accordingly, per share amounts are not comparable
between the Predecessor Period and the Successor Period. Compared to 2001, we
expect our net loss in 2002 to increase as wireless cable assets are fully
depreciated and wireless cable market operations are closed upon conversion of
our wireless cable subscriber base.

BALANCE SHEET AS OF DECEMBER 31, 2001, COMPARED TO THE BALANCE SHEET AS OF
DECEMBER 31, 2000

     Material changes to balance sheet accounts from 2000 to 2001 were as
follows:

     - The decrease in subscriber receivables resulted primarily from a decrease
       of 27,000 average wireless cable subscribers.

     - The decrease in other receivables resulted primarily from a decrease in
       receivables from DIRECTV resulting from a change in the structure of
       certain subsidy programs and from lower installs compared to the prior
       year.

     - The decrease in systems and equipment, and license and leased license
       investment was due to the impairment of long-lived assets.

     - The decrease in net other assets resulted from the elimination of an
       intangible asset created in Fresh Start Accounting and from normal
       amortization of intangible assets. In addition, long-term restricted
       cash, representing restricted investments in bank certificates pledged as
       collateral for long-term capital leases, now have less than a year to
       maturity and are classified as short-term restricted assets.

     - The decrease in accounts payable and accrued liabilities is primarily due
       to a decrease in deferred revenue resulting from a change in the
       structure of certain subsidy programs from DIRECTV, from lower
       programming and subscriber related payables resulting from a lower
       subscriber count in the current year, and from a reduction in accrued
       taxes. This was partially offset by the establishment of a canceled
       subscriber chargeback reserve in 2001 for 1999 through 2001 deferred
       revenue related to our agency relationship with DIRECTV.

                                        38
<PAGE>

     - The decrease in other long-term liabilities is primarily due to a
       reclassification to current liabilities of certain tax related
       obligations.

LIQUIDITY AND CAPITAL RESOURCES

     The broadband wireless business is capital-intensive. Since inception, we
have spent funds to lease or otherwise acquire MMDS channel rights in various
markets and operating systems, to construct video operating systems and two
Internet systems, and to finance initial system operating losses. Our primary
sources of capital have been subscription fees, debt financing, the sale of
common stock, and the sale of MMDS spectrum rights that were not essential to
our business strategy. The approval by the FCC of the use of MMDS spectrum for
digital two-way communications services and the FCC's flexible use authorization
will allow us to use our spectrum to provide fixed, portable and, ultimately,
mobile broadband wireless services such as high-speed Internet access services,
voice over IP and wireless telecommunications services. The growth of our
business by using our spectrum to provide broadband data and voice
communications services will require substantial investment in capital
expenditures.

     Cash used in operations was $2.9 million during the year ended December 31,
2001, compared to $1.9 million during the year ended December 31, 2000. Cash
used in operations during 2001 was primarily due to increased subscriber
acquisition costs related to our DIRECTV agency relationship, and severance
payments related to a reduction in force in the first quarter and to pay accrued
property taxes and other liabilities. Cash provided by operations during 2000
included higher revenue received from our agency relationship with DIRECTV due
to higher installs in 2000. Cash provided by operations during the year ended
December 31,1999, was $8.0 million. The increase in cash used in operations from
1999 to 2000 resulted primarily from recognition during 2000 of deferred agency
revenue received in 1999 from our alliance with DIRECTV, and from payment of
previously accrued reorganization costs.

     Cash used in investing activities principally relates to the acquisition
and installation of subscriber equipment, the upgrade of transmission equipment
in certain markets, and the acquisition of MMDS spectrum rights, partially
offset by the sale of MMDS spectrum rights that are not a part of our strategic
plan. Cash used in investing activities was $1.8 million in 2001 compared to
$4.6 million in 2000. Cash used in investing activities during 2001 included
expenditures for engineering, legal, site acquisition, and other costs related
to the acquisition of MMDS channel rights. Cash used in investing activities in
2000 included expenditures related to our applications for two-way licenses,
partially offset by $4.5 million from the exchange of our equity interest in
Wireless One and approximately $780,000 from the sale-leaseback of our
communications towers. Cash used in investing activities was $8.9 million in
1999. Cash used in investing activities decreased from 1999 to 2000 primarily
due to $4.5 million received in the first nine months of 2000 from the exchange
of our equity interest in Wireless One. In addition, we had lower expenditures
for systems and equipment related to our wireless cable business, partially
offset by higher expenditures for engineering, legal, site acquisition, and
other costs related to our application for two-way licenses.

     Cash used in financing activities was $2.0 million during 2001 compared to
$285,000 during 2000 and $878,000 during 1999. Cash used in financing activities
in 2001 was for payments on our BTA debt and capital lease obligations related
to the sale and leaseback of our 34 communications towers. Cash used by
financing activities during 2000 also included principal payments on our BTA
debt and capital lease obligations. This was partially offset by $1.5 million in
cash proceeds received from the exercise of employee stock options. Cash used
during 1999 was for principal payments on our BTA debt, capital lease
obligations and other notes payable, several of which have been fully repaid,
offset by $1.1 million in cash proceeds from employee stock option exercises.

     At March 31, 2002, we had approximately $13.9 million of unrestricted cash
and cash equivalents and $300,000 in restricted cash representing collateral
securing various outstanding letters of credit to certain of our vendors. As set
forth in note 1(b) to the consolidated financial statements, the consolidated
financial statements contained in this report have been prepared on a "going
concern" basis, which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. In conjunction
with its 2001 year end audit, KPMG LLP, our independent accountants, has issued
an audit opinion with respect to

                                        39
<PAGE>

our 2001 consolidated financial statements which includes a qualification that
raises substantial doubts about our ability to continue as a going concern. The
consolidated financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

     KPMG LLP has stated in its report that the qualification in their report
which raises substantial doubt about our ability to continue as a going concern
is based on our history of recurring net operating losses and our resulting
dependence on access to additional financing to avoid the negative cash balance
that we project for the second quarter of 2003. We have discussed these two
matters in Item 1, "Business -- Risk Factors -- We are pursuing a new business
that we have not previously operated on a large scale. We may not be able to
successfully implement our long-term business strategy or correct our history of
losses," and "Business -- Risk Factors -- We may not be able to obtain the
additional financing necessary to implement our long-term business strategy on
satisfactory terms and conditions."

     As we have described elsewhere in this report,

     - additional capital will be required to implement our long-term business
       plan and we likely will seek additional capital or alternative financing
       in the next 12 months,

     - we have in place a business plan that management believes will allow
       Nucentrix to continue to operate in the normal course of business,
       without obtaining additional financing or deploying any new Internet
       markets in 2002, at least through the first quarter of 2003, and

     - if we are unable to obtain financing in a timely manner and on acceptable
       terms, we have an alternative plan that management believes will allow
       Nucentrix to continue operations at least through the second quarter of
       2003. This plan would include reducing or eliminating spectrum carrying
       and construction costs in non-strategic markets, reducing corporate
       overhead (including personnel reductions) and reducing or eliminating
       other discretionary expenditures.

FUTURE CASH REQUIREMENTS

     Our goal is to become a leading provider of advanced wireless services in
our markets. To implement our long-term business strategy we intend to first
offer high-speed fixed and portable broadband Internet access to medium-sized
and small businesses, SOHOs, telecommuters, and residential consumers in our
markets. Subject to market demand, technological developments and interference
regulations, a flexible use allocation in the 2.5 GHz band could allow us
ultimately to offer mobile 3G and voice services.

     The growth of our business by using our spectrum to provide fixed, portable
or mobile broadband Internet service will require substantial investment in
capital expenditures. We expect that next generation MMDS technology will
provide greater coverage capabilities by addressing line-of-sight limitations
that exist in current equipment, and will allow customers to install and upgrade
customer premises equipment themselves. These improvements should allow us to
reduce subscriber-related costs and operating expenses; however, the development
and launch of broadband wireless MMDS networks will be capital intensive, and
additional capital will be required to implement our long term strategy of
providing advanced wireless services in medium and small markets.

     We estimate that a launch of a next generation broadband wireless system
providing high-speed Internet access in a typical market will involve an initial
expenditure of approximately $500,000 to $1.5 million for network equipment,
depending upon the system design and type and sophistication of the equipment.
In addition, we estimate that the acquisition and installation of each new
Internet subscriber will cost between $500 and $800 depending upon the type of
customer. This includes charges for equipment, labor and direct commissions.
This may be offset partially by installation and other up-front fees. Other
launch costs include the cost of securing adequate space for marketing and
operational facilities, as well as costs related to employees. As a result of
these costs, operating losses are likely to be incurred by a system during the
start-up period.

     As part of our long-term plan to focus on the use of our spectrum for
broadband Internet and other advanced wireless services, in March 2002 we
announced agreements to convert substantially all of our

                                        40
<PAGE>

wireless cable subscribers to DIRECTV and Time Warner Cable programming. We
estimate that approximately 63,000 of our subscribers will be eligible for
conversion to DIRECTV programming, and approximately 6,000 subscribers will be
eligible for conversion to Time Warner Cable.

     As a result of this strategic shift in the focus of our business, revenues
and cash flows from our subscription television business will decline
substantially as our wireless cable subscribers convert to DIRECTV, Pegasus or
Time Warner Cable or otherwise disconnect their service with us. Except for a
nominal residual royalty payment and recognition of deferred revenue related to
cash received at the time of conversion, we do not expect our existing wireless
cable subscriber base to continue to generate material revenues or cash flows
for the Company after March 2003. Although we intend to reduce expenditures
associated with our wireless cable business, ongoing costs of maintaining our
FCC spectrum licenses and leases, as well as other corporate overhead, will
exceed revenues as we implement the conversion program.

     We are continuing to evaluate the development of technology for MMDS
service, the commitments by other MMDS operators to specific technology
platforms, the accessibility of capital markets, and the availability of other
sources of financing. However, until we are able to deploy a technology platform
for which another major MMDS operator has made a substantial purchase
commitment, and have obtained financing on satisfactory terms and conditions, we
intend to continue to look for efficiencies, maximize our cash resources and
preserve strategic spectrum resources. This likely will result in deployment of
no new Internet markets in 2002. We expect that cash on hand of $13.9 million at
March 31, 2002, and cash generated from operations will be sufficient to fund
operations in the normal course of business at least through the first quarter
of 2003.

     The consolidated financial statements do not reflect any adjustments that
might result from the outcome of these uncertainties.

     We are continuing to evaluate our near and long-term capital needs, and
likely will seek additional capital in the next 12 months. Options for raising
additional capital include the sale of debt or equity securities, borrowings
under secured or unsecured loan arrangements, including vendor equipment
financing, and sales of assets. We can provide no assurance that such capital or
financing will be available in a timely manner or on satisfactory terms. If the
Company is unable to obtain financing in a timely manner and on acceptable
terms, management has developed and intends to implement a plan that management
believes will allow the Company to continue operations at least through the
second quarter of 2003. This plan would include reducing or eliminating spectrum
carrying and construction costs in non-strategic markets, reducing corporate
overhead (including personnel reductions) and reducing or eliminating other
discretionary expenditures.

     As set forth in note 1(b) to the consolidated financial statements, the
consolidated financial statements contained in this report have been prepared on
a "going concern" basis, which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. In conjunction
with its 2001 year end audit, KPMG LLP, our independent accountants, has issued
an audit opinion with respect to our 2001 consolidated financial statements
which includes a qualification that raises substantial doubts about our ability
to continue as a going concern. The consolidated financial statements do not
include any adjustments that might result from the outcome of this uncertainty.

     KPMG LLP has stated in its report that the qualification in their report
which raises substantial doubt about our ability to continue as a going concern
is based on our history of recurring net operating losses and our resulting

     As we have described above in this section and elsewhere in this report,

     - additional capital will be required to implement our long-term business
       plan and we likely will seek additional capital or alternative financing
       in the next 12 months,

                                        41
<PAGE>

     - we have in place a business plan that management believes will allow
       Nucentrix to continue to operate in the normal course of business,
       without obtaining additional financing or deploying any new Internet
       markets in 2002, at least through the first quarter of 2003, and

       and construction costs in non-strategic markets, reducing corporate
       overhead (including personnel reductions) and reducing or eliminating
       other discretionary expenditures.

EFFECTS OF REORGANIZATION

     Our company and certain of our subsidiaries file a consolidated federal
income tax return. Subsidiaries in which we own less than 80% of the voting
stock will file separate federal income tax returns. We have had no material
state or federal income tax expense since inception. As of December 31, 1999 and
before taking into consideration the effects of the reorganization, we had
approximately $366.8 million in net operating losses for U.S. federal income tax
purposes, expiring in years 2013 through 2019. We estimate that approximately
$38 million of the above losses relate to various acquisitions and as such are
subject to certain limitations.

     We adopted Fresh Start Reporting on the April 1, 1999, Effective Date of
our Plan in accordance with SOP 90-7. Fresh Start Reporting resulted in a new
reporting entity with assets and liabilities adjusted to fair value and
beginning retained earnings set to zero. Liabilities subject to compromise also
were adjusted to zero in the debt discharge portion of the Fresh Start Reporting
entry. In addition, on the Effective Date our outstanding common stock was
canceled and newly issued shares of common stock and warrants were distributed
to certain creditors in satisfaction of their claims against us. In connection
with the debt discharge, Nucentrix recorded an extraordinary gain of
approximately $174 million.

     Federal income tax law generally requires that the amount of income from
discharge of indebtedness that occurs in connection with a Chapter 11 bankruptcy
be used to reduce federal tax attributes. Generally, the reduction is applied to
reduce net operating loss carryforwards, followed by other tax attributes
including the basis of certain assets and the tax basis of subsidiary stock. An
election exists to reduce the basis of depreciable assets first, which can be
favorable under certain circumstances. Management has elected to apply the
required reduction first to tax basis in depreciable assets, and then to net
operating loss carryforwards. The amount of reduction in the tax basis of
depreciable assets was approximately $56 million, leaving approximately $183
million in remaining basis in depreciable assets. The amount of reduction in net
operating loss carryforwards was approximately $118 million, leaving
approximately $222 million in remaining net operating loss carryforwards at
December 31, 2000.

     In addition to the permanent Tax Attribute Reduction, we also must limit
the annual deduction of pre-bankruptcy net operating losses and "built-in
deductions" to an amount no greater than the fair market value of Nucentrix
immediately after the reorganization, multiplied by the long-term tax exempt
rate. The annual limitation applicable to our pre-bankruptcy net operating
losses and "built-in" deductions currently is estimated to be approximately $7.3
million.

CRITICAL ACCOUNTING POLICIES

     The consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States, which require the
Company to make estimates and assumptions. The Company's significant accounting
policies and methods used in the preparation of the consolidated financial
statements are discussed in note 1 of the notes to consolidated financial
statements. The Company believes that of its significant accounting policies,
the following may involve a higher degree of judgment and complexity.

     Revenues currently consist primarily of monthly fees paid by wireless cable
subscribers for basic programming, premium programming, equipment rental, and
other miscellaneous fees, and revenues from our agency relationship with DIRECTV
(which will include revenues from DIRECTV and others in 2002 from

                                        42
<PAGE>

the conversion program discussed in Item 1, "Business" of this report). Revenues
also include fees generated from Internet operations in Austin and
Sherman-Denison, Texas. Unless the context requires otherwise, all references to
"subscribers" or "systems" are to wireless cable subscribers and systems because
revenues and subscribers from Internet business were immaterial in 2001
(approximately 1% of consolidated revenues).

     Subscription revenues from wireless cable subscribers and continuing
monthly service fees from DIRECTV for each DIRECTV customer generated are
recognized as service is provided. If the Company does not meet minimum
subscriber benchmarks each year, the DIRECTV continuing monthly service fee will
be reduced.

     Effective January 1, 2001, wireless cable and DIRECTV installation revenue,
and revenue received from our agency relationship with DIRECTV (except for
continuing monthly service fees, which are recognized as received), is
recognized to the extent of direct selling costs incurred, and the remainder is
deferred and amortized to income over the expected subscriber relationship
period of three years. A chargeback reserve is recorded for all DIRECTV
contingencies. Prior to 2001, wireless cable installation revenue was offset
against the nonrecoverable portion of installation costs, with the excess cost
capitalized and amortized to depreciation expense over the expected subscriber
relationship period of three years. Prior to 2001, DIRECTV installation revenues
(cash received directly from the customer in conjunction with the sale) was
offset against direct incremental costs, with the resulting amount recorded as a
net asset. This asset, referred to as "subscriber acquisition costs," was
amortized as a component of SG&A expense in proportion to the revenues projected
to be generated over the expected subscriber relationship period. Revenue from
our agency relationship with DIRECTV (other than monthly service fees) was
recognized as the contingencies related to each revenue component were resolved.
A chargeback reserve was not recorded for canceled subscribers. The Company
revised the application of its SFAS No. 51 accounting for wireless cable
installation and DIRECTV revenues prospectively, effective January 1, 2001, as
discussed above. See "MD&A -- Revised Application of Accounting Policy and
Restatement of 2001 Quarterly Results."

     The direct costs of wireless cable installations include reception
materials and equipment on subscriber premises and installation labor, which are
amortized over the useful life of the asset (presently five years) for the
recoverable portion and the estimated average subscription term (presently three
years) for the nonrecoverable portion of such costs. The nonrecoverable portion
of the cost of a subscriber installation becomes fully depreciated upon
disconnection of the subscriber. Prior to 2001, the Company capitalized only the
excess of non-recoverable costs of wireless cable installations over
installation revenues. The Company revised the application of its SFAS No. 51
accounting for wireless cable non-recoverable installation costs prospectively,
effective January 1, 2001, to discontinue the netting of installation fees
against nonrecoverable costs of subscriber installations. See "MD&A -- Change in
Accounting Policies and Restatement of 2001 Quarterly Results."

     Our revenue recognition for wireless cable and DIRECTV installation
revenue, and amortization of the recoverable portion of direct costs of wireless
cable installations, is based on assumptions regarding our expected subscriber
term. The expected subscriber term of three years currently used for these
purposes is based on historic subscriber churn rates. If a different subscriber
term was used, the revenue amounts reported could be materially different than
amounts reported in this report, and if the subscriber term changes in future
years, the amounts reported in future years would not be comparable to the years
reported in this report.

     The direct incremental costs incurred in generating a customer relationship
with DIRECTV, comprised of material, equipment and labor, are recorded as an
asset. This asset, referred to as "subscriber acquisition costs," is amortized
as a component of SG&A expense over the expected subscriber relationship period
of three years.

     Our long-term operating assets, which include headend and base station
equipment, are recorded at cost and amortized on a straight-line basis over the
estimated useful lives. Our licenses and leased license investments, which
include our FCC licenses and spectrum leases, are amortized from the inception
of service in each market. In accordance with SFAS No. 121, we review our
long-lived assets and certain intangibles for impairment whenever events or
changes in circumstances indicate that the carrying amount of these assets may
not be recoverable. Recoverability of assets to be held and used is measured by
a comparison of the
                                        43
<PAGE>

carrying amount of an asset to the future net cash flows expected to be
generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the net asset exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value less
costs to sell. In the fourth quarter of 2001, we wrote down our systems and
equipment, and license and leased license investments by a total of $14.1
million. See "MD&A -- Results of Operations for the Three Years Ended December
31, 2001 -- Impairment of Long-Lived Assets" and note 2 to the consolidated
financial statements.

REVISED APPLICATION OF ACCOUNTING POLICY AND RESTATEMENT OF 2001 QUARTERLY
RESULTS

     The Company revised its application of SFAS No. 51, Financial Reporting by
Cable Television Companies ("SFAS No. 51"), for its wireless cable service and
DIRECTV programming service during the fourth quarter of 2001, retroactively
effective to the beginning of 2001. Prior to this revision:

     - wireless cable installation revenue was offset against the nonrecoverable
       portion of installation costs, with the excess cost capitalized and
       amortized to depreciation expense over the expected subscriber
       relationship period of three years,

     - the excess nonrecoverable costs of a wireless cable installation over
       installation revenue were capitalized and amortized to depreciation
       expense over the expected subscriber relationship period of three years,

     - DIRECTV installation revenue was offset against direct incremental costs,
       with the resulting amount recorded as a net asset,

     - this asset, referred to as "subscriber acquisition costs," was amortized
       as a component of SG&A expense in proportion to the revenues projected to
       be generated over the expected subscriber relationship period, and

     - revenue from our agency relationship with DIRECTV (other than monthly
       service fees) was recognized as the contingencies related to each revenue
       component were resolved; a chargeback reserve was not recorded for
       canceled subscribers.

     The revised application of SFAS No. 51 resulted in the following changes to
the Company's accounting practices:

     - wireless cable and DIRECTV installation revenue, and revenue received
       from our agency relationship with DIRECTV (except for continuing monthly
       service fees, which are recognized as received), is recognized to the
       extent of direct selling costs incurred, the remainder is deferred and
       amortized to income over the expected subscriber relationship period of
       three years, and a chargeback reserve is recorded for all DIRECTV
       contingencies, and

     - direct incremental costs incurred in generating a customer relationship
       with DIRECTV, comprised of material, equipment and labor, is recorded as
       an asset and amortized as a component of SG&A expense over the expected
       subscriber relationship period of three years.

     Since the revised application of SFAS No. 51 was retroactively effective to
the beginning of 2001, financial information for the first three quarters of
2001 has been revised. The revised application of SFAS No. 51 resulted in $3.2
million of additional revenue in the first three quarters of 2001. Also, in
connection with its revised application of SFAS No. 51 in 2001, the Company
reduced revenues to establish a $2.2 million chargeback reserve for canceled
subscribers. In addition, in 2001 the Company adjusted the fair value of its
liabilities at Fresh Start and correspondingly reduced revenues that had been
deferred and recognized since Fresh Start for a net reduction in revenues in the
first three quarters of $2.2 million. Other miscellaneous adjustments reduced
revenues in the first three quarters a total of approximately $200,000.

                                        44
<PAGE>

     The net effect of the Company's changes on its financial results for the
first, second and third quarters of 2001, as previously reported in the
Company's Quarterly Reports on Form 10-Q for such quarters, was:

     - a decrease in reported revenues from:

      - $13.9 million to $13.9 million (0%) in the first quarter,

      - $13.3 million to $12.6 million (5.3%) in the second quarter, and

      - $12.6 million to $11.9 million (5.6%) in the third quarter,

     - an increase in reported operating loss from:

      - $6.7 million to $7.9 million (17.9%) in the first quarter,

      - $6.4 million to $7.2 million (12.5%) in the second quarter, and

      - $5.7 million to $6.7 million (17.5%) in the third quarter,

     - an increase in reported net loss and net loss per basic and diluted
       common share from:

      - $6.5 million ($0.63) to $7.7 million ($0.75) (18.5%) in the first
        quarter,

      - $6.2 million ($0.60) to $7.1 million ($0.68) (14.5%) in the second
        quarter, and

      - $5.7 million ($0.55) to $6.7 million ($0.64) (17.5%) in the third
        quarter.

     See note 16 of the notes to consolidated financial statements. For periods
prior to 2001, neither the revised application of SFAS No. 51 nor the other
changes discussed above had a material impact on the Company's consolidated
financial statements.

     The Company's long-term operating assets are recorded at cost and amortized
on a straight-line basis over the estimated useful lives, from one to 16 years.
These assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable. Included
in these operating assets are costs of headend and base station equipment, which
historically have been used in the operation of our wireless cable television
business. As we implement our strategic shift in the use of our spectrum from
video service to broadband wireless Internet and other advanced wireless
services, we expect to be able to use our headends and base stations in the
provision of such services.

     The Company's licenses and leased license investments, which include costs
incurred to acquire and/or develop spectrum rights, are amortized over 15 years
beginning with the inception of service in each market since Fresh Start and
12.5 years for those markets that existed at Fresh Start.

COMMITMENTS AND CONTINGENCIES

     We are a party to several purported class action lawsuits alleging that we
overcharged our customers for administrative late fees, breached warranties in
connection with our subscription television service, and/or violated various
federal and state requirements relating to consumer credit and leasing
transactions. We believe the lawsuits are without merit and intend to vigorously
defend them. While it is not feasible to predict or determine the final outcome
of these proceedings or to estimate the amounts or potential range of loss with
respect to these matters, and while we do not expect such an adverse outcome, we
believe that an adverse outcome in one or more of these proceedings could have a
material adverse effect on our consolidated financial condition, results of
operations and/or cash flows. For a more detailed discussion of legal matters,
see Item 3, "Legal Proceedings."

     In May 2000, we entered into a definitive agreement to acquire all of the
MDS, MMDS and ITFS spectrum licenses, lease rights and other assets of Wireless
Cable of Rockford, LLC and Allen Leeds in Rockford, Illinois. In October 2001,
the FCC dismissed the BTA owner's application for consent to assign the Rockford
BTA to the Company. As a result, the Company or the BTA owner may terminate the
purchase agreement, or the parties may determine to modify the agreement. In
November 2001, the BTA owner filed a

                                        45
<PAGE>

Petition for Reconsideration of the FCC's decision. If the parties determine to
proceed, the transaction will be subject to other customary closing conditions
including due diligence.

CONTRACTUAL OBLIGATIONS

     The Company's contractual obligations include long-term debt (primarily
related to BTA installment notes), capital lease obligations (primarily related
to tower leases), operating leases (primarily related to spectrum leases), and
other long-term obligations (purchase installments for spectrum license
acquisitions and settlement payments), as summarized below.

INFLATION

     We do not believe that inflation has had or is likely to have any
significant impact on our operations. We believe that we will be able to
increase subscriber rates, if necessary, to keep pace with inflationary
increases in costs.

RECENTLY ISSUED ACCOUNTING PRINCIPLES

     In June 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 142, "Goodwill and Other Intangibles." SFAS 142 requires that ratable
amortization of goodwill be replaced with periodic fair-value based tests of the
goodwill's impairment, and that intangible assets other than goodwill be
amortized over their useful lives. Additionally, under the provision of the new
accounting standard, an acquired intangible asset should be separately
recognized if the benefit of the intangible asset is obtained through
contractual or other legal rights, or if the intangible asset can be sold,
transferred, licensed, rented, or exchanged, regardless of the acquirer's intent
to do so. The provisions of SFAS 142 will be effective for fiscal years
beginning after December 15, 2001, and will thus be adopted by the Company, as
required, in fiscal year 2002. The impact of SFAS 142 on the Company's financial
statements has not yet been determined.

     In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations," which addresses financial accounting and reporting
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. The standard applies to legal obligations
associated with the retirement of long-lived assets that result from the
acquisition, construction, development, and/or normal use of the asset. SFAS No.
143 requires that the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred if a reasonable
estimate of fair value can be made. The fair value of the liability is added to
the carrying amount of the associated asset and this additional carrying amount
is depreciated over the life of the asset. The liability is accreted at the end
of each period through charges to operating expense. If the obligation is
settled for other than the carrying amount of the liability, the Company will
recognize a gain or loss on settlement. The Company is required to adopt the
provisions of SFAS No. 143 no later than the beginning of fiscal year 2003, with
early adoption permitted. The Company does not expect the adoption of SFAS No.
143 to have a material effect on its consolidated financial condition, results
of operations or cash flows.

     In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets," which addresses financial
accounting and reporting for the impairment or disposal of long-lived assets.
While SFAS No. 144 supersedes SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of," it retains many
of the fundamental provisions of that
                                        46
<PAGE>

statement. SFAS No. 144 becomes effective for fiscal years beginning after
December 15, 2001, with early applications encouraged. The Company does not
expect the adoption of this statement to have a material effect on its
consolidated financial condition, results of operations or cash flows.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK

     We are exposed to market risk from changes in marketable securities
(certificates of deposit). At December 31, 2001, our marketable securities were
recorded at a fair value of approximately $300,000, with an overall weighted
average return of approximately 3% and an overall weighted average life of less
than 1 year. The marketable securities held by us have exposure to price risk,
which is estimated as the potential loss in fair value due to a hypothetical
change of 30 basis points (10% of our overall average return on marketable
securities) in quoted market prices. This hypothetical change would have an
immaterial effect on the recorded value of the marketable securities.

     We are not exposed to material future earnings or cash flow fluctuations
from changes in interest rates on long-term debt since 100% of our long-term
debt is at a fixed rate as of December 31, 2001. The fair value of our long-term
debt at December 31, 2001, is estimated to be $10.6 million based on the overall
rate of the long-term debt of 9.5% and an overall maturity of 5 years compared
to terms and rates currently available in long-term financing markets. To date,
we have not entered into any derivative financial instruments to manage interest
rate risk and are not currently evaluating the future use of any such financial
instruments.

     We do not currently have any exposure to foreign currency transaction gains
or losses. All business transactions are in U.S. dollars.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Nucentrix Broadband Networks, Inc.

     We have audited the accompanying consolidated balance sheets of Nucentrix
Broadband Networks, Inc. and subsidiaries as of December 31, 2001 and 2000 and
the related consolidated statements of operations, stockholders' equity and cash
flows for the years ended December 31, 2001 and 2000, the periods from January
1, 1999 to April 1, 1999, the effective date of the reorganization discussed in
the fourth paragraph below (the "Effective Date"), and from the Effective Date
to December 31, 1999. In connection with our audits of the consolidated
financial statements, we also have audited the accompanying financial statement
schedule. These consolidated financial statements and financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements based on our
audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. 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 Nucentrix
Broadband Networks, Inc. and subsidiaries as of December 31, 2001 and 2000, and
the results of their operations and their cash flows for the years ended
December 31, 2001 and 2000, the periods from the Effective Date to December 31,
1999 and from January 1, 1999 to the Effective Date, in conformity with
accounting principles generally accepted in the United States of America. Also,
in our opinion, the related financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

     The accompanying consolidated financial statements have been prepared
assuming the Company will continue as a going concern. As discussed in note 1(b)
to the consolidated financial statements, the Company's recurring losses from
operations and the resulting dependence upon access to additional financing
raise substantial doubt about its ability to continue as a going concern.
Management's plans with regard to these matters are also discussed in note 1(b).
The consolidated financial statements and financial statement schedule do not
include any adjustments that might result from the outcome of this uncertainty.

     As discussed in note 1(c) to the consolidated financial statements, upon
consummation of a prenegotiated Plan of Reorganization under Chapter 11 of the
United States Bankruptcy Code on the Effective Date, the Company adopted Fresh
Start Reporting in accordance with American Institute of Certified Public
Accountants Statement of Position 90-7, Financial Reporting by Entities in
Reorganization Under the Bankruptcy Code. As a result of the application of
Fresh Start Reporting, the consolidated financial statements of Nucentrix
Broadband Networks, Inc. and subsidiaries for the period from the Effective Date
to December 31, 1999 are presented on a different cost basis than those for
periods prior to the Effective Date, and accordingly, are not directly
comparable.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
             (TABLES IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

(1) GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  (a) DESCRIPTION OF BUSINESS

     Nucentrix Broadband Networks, Inc. ("Nucentrix" or the "Company") provides
broadband wireless Internet and wireless subscription television services using
up to approximately 200 megahertz ("MHz") of radio spectrum licensed by the
Federal Communications Commission ("FCC") in the 2.1 gigahertz ("GHz") and 2.5
GHz bands, primarily in medium and small markets across Texas, Oklahoma and the
Midwestern United States. The Company owns the basic trading area ("BTA")
authorization, or otherwise licenses or leases spectrum, in over 90 markets. On
average, the Company owns or leases 151 MHz of spectrum per market. This
spectrum commonly is referred to as Multichannel Multipoint Distribution
Service, or "MMDS," and Instructional Television Fixed Service, or "ITFS." The
Company currently provides high-speed wireless Internet access service in two
markets, primarily to medium-sized and small businesses, small offices/home
offices and telecommuters. Nucentrix also provides wireless subscription
television service, commonly referred to as "wireless cable," in 57 markets.

     In March 2002, as part of the Company's long-term plan to focus on the use
of its spectrum for broadband Internet and other advanced wireless services, the
Company announced the signing of agreements with DIRECTV, Inc. ("DIRECTV"),
Pegasus Satellite Television, Inc. ("Pegasus") and an affiliate of Time Warner
Cable ("Time Warner Cable") to convert substantially all of the Company's
wireless cable subscribers to programming provided by these entities.

  (b) GOING CONCERN AND LIQUIDITY

     Nucentrix's consolidated financial statements have been presented on a
going concern basis which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business.

     The Company has incurred operating losses of $41.2 million, $27.5 million,
$17.1 million, and $5.4 million for the years ended December 31, 2001 and 2000,
for the period from the Effective Date to December 31, 1999, and for the period
from January 1, 1999, to the Effective Date, respectively. The growth of the
Company's business by using its spectrum to provide fixed, portable or mobile
broadband Internet service will require substantial investment in capital
expenditures, and additional capital will be required to implement the Company's
long term strategy of providing advanced wireless services in medium and small
markets. The Company currently is focused on validating the most efficient
technology platform from which to deliver its services, and during the next 12
months, the Company likely will seek to raise capital for spectrum maintenance,
operating expenses and/or to fund deployment. There can be no assurance that
additional capital will be available on acceptable terms or in a timely manner.

     As part of its long-term shift in strategic focus, the Company announced
the signing of agreements with DIRECTV, Pegasus and Time Warner Cable to convert
substantially all of its wireless cable subscribers to programming provided by
these entities. In exchange for each subscriber converted, the Company will
receive a conversion payment and, in the case of subscribers converted to
DIRECTV and Pegasus, an equipment subsidy, installation payment and residual
royalty. As a result of these transactions, revenues and cash flows from the
Company's wireless cable business will decline substantially as its wireless
cable subscribers convert to DIRECTV or Time Warner Cable or otherwise
disconnect their service. Except for a nominal residual royalty payment, the
Company does not expect its existing wireless cable subscriber base to generate
material revenues or cash flows for the Company after March 2003. Although the
Company intends to reduce expenditures associated with its wireless cable
business, ongoing costs of maintaining the Company's FCC spectrum licenses and
leases, as well as other corporate overhead, will exceed recurring revenues as
the Company implements its conversion program.

              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company is continuing to evaluate the technology for MMDS service, the
commitments by other MMDS operators to specific technology platforms, the
accessibility of capital markets, and the availability of other sources of
financing. However, until the Company is able to deploy a technology platform
for which another major MMDS operator has made a substantial purchase
commitment, and has obtained financing on satisfactory terms and conditions, the
Company intends to continue to look for efficiencies, maximize its cash
resources and preserve its strategic spectrum resources. This likely will result
in deployment of no new Internet markets in 2002. The Company expects that cash
on hand, cash generated from operations, and equipment financing will be
sufficient to fund operations in the normal course of business at least through
the first quarter of 2003.

     If the Company is unable to obtain financing in a timely manner and on
acceptable terms, management has developed and intends to implement a plan that
would allow the Company to continue operations at least through the second
quarter of 2003. This plan would include reducing or eliminating spectrum
carrying and construction costs in non-strategic markets, reducing corporate
overhead (including personnel reductions) and reducing or eliminating other
discretionary expenditures.

     The consolidated financial statements do not include any adjustments that
might result from the outcome of the uncertainties discussed above.

  (c) FINANCIAL RESTRUCTURING

     On December 4, 1998, Nucentrix filed a voluntary, prenegotiated Plan of
Reorganization (the "Plan" or "Plan of Reorganization") under Chapter 11 of the
U.S. Bankruptcy Code, with the prepetition support from holders of more than 70%
in principal amount of its 13% Senior Notes ("Old 13% Notes") and 14% Senior
Notes ("Old 14% Notes") (collectively, "the Old Senior Notes"). On March 15,
1999, the Bankruptcy Court confirmed the Plan, which became effective on April
1, 1999 (the "Effective Date"). On the Effective Date, the Company changed its
name from Heartland Wireless Communications, Inc. ("Heartland") to Nucentrix
Broadband Networks, Inc. On the Effective Date, Nucentrix canceled all issued
and outstanding common stock, stock options and warrants and issued 10,000,000
shares of new common stock and warrants to purchase 825,000 shares of common
stock. Nucentrix also is obligated under the Plan to issue warrants to purchase
an additional 275,000 shares of common stock to certain classes of or claims
against and/or interests in Nucentrix, which will become issuable upon the
resolution of certain pending litigation claims.

     Nucentrix continued business operations as a debtor-in-possession until the
Plan was fully consummated. Prior to April 1, 1999, the obligations of Nucentrix
that were eligible for compromise under the Plan were classified as Liabilities
Subject to Compromise on the Company's consolidated balance sheets as of
December 31, 1998, and March 31, 1999. As of December 4, 1998, Nucentrix
discontinued the accrual of interest and amortization of deferred debt issuance
costs and discounts to notes payable related to Liabilities Subject to
Compromise. On March 15, 1999, the U.S. Bankruptcy Court for the District of
Delaware confirmed the Plan, and Nucentrix consummated the Plan on April 1,
1999.

     On April 1, 1999, Nucentrix adopted Fresh Start Reporting in accordance
with American Institute of Certified Public Accountants Statement of Position
90-7, "Financial Reporting by Entities in Reorganization under the Bankruptcy
Code" ("SOP 90-7"). Fresh Start Reporting resulted in a new reporting entity
with assets and liabilities adjusted to fair value and beginning retained
earnings set to zero. Liabilities Subject to Compromise were adjusted to zero in
the debt discharge portion of the Fresh Start Reporting. In connection with the
debt discharge, Nucentrix recorded an extraordinary gain of approximately $174
million. The effects

              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Federal income tax law requires that the amount of income from discharge of
indebtedness that occurs in connection with a Chapter 11 bankruptcy be used to
permanently reduce federal tax attributes. These reductions may be applied to
one or more tax items, including but not limited to pre-bankruptcy net operating
loss carryforwards, the tax basis of certain assets and the tax basis of
subsidiary stock ("Tax Attribute Reduction"). Management has elected to apply
the required reduction first to tax basis in depreciable assets, and then to net
operating loss carryforwards. The amount of reduction in the tax basis of
depreciable assets was approximately $56 million. The amount of reduction in net
operating loss carryforwards was approximately $118 million, which left
approximately $222 million in remaining net operating loss carryforwards at
December 31, 2000 (see note 10).

     During 2001, the Company determined that revenue of approximately $2.5
million should not have been deferred and recognized beyond the Fresh Start
Reporting date. The Company made this change as of December 31, 2001, by
reducing intangibles associated with the Fresh Start Reporting.

  (d) PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of Nucentrix and
its majority-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.

  (e) CASH AND CASH EQUIVALENTS

     Nucentrix considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents. Cash and cash
equivalents consist of money market funds, overnight repurchase agreements and
other investment securities.

  (f) RESTRICTED ASSETS

     Restricted assets consist of bank certificates of deposit with an original
maturity of less than one year. These investments are considered held to
maturity and are stated at amortized cost which approximates fair value. The
Company has pledged these certificates of deposit as letters of credit for
capital leases with remaining terms of less than one year.

  (g) IMPAIRMENT OF LONG-LIVED ASSETS

     Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting
for the Impairment of Long-Lived Assets to be Disposed of," requires that
long-lived assets and certain intangibles be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. Recoverability of assets to be held and used is measured
by a comparison of the carrying amount of an asset to the future net cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the net asset exceeds the fair value of the assets. Assets to
be disposed of are reported at the lower of the carrying amount or fair value
less costs to sell.

  (h) SYSTEMS AND EQUIPMENT

     Systems and equipment are recorded at cost and principally include the cost
of transmission equipment as well as direct costs of subscriber installations
(see note 3). Upon installation, depreciation and amortization of systems and
equipment is recorded on a straight-line basis over the estimated useful lives,
from one to 16 years.

     The direct costs of wireless cable subscriber installations include
reception materials and equipment on subscriber premises and installation labor,
which are amortized over the useful life of the asset (presently five years) for
the recoverable portion and the estimated average subscription term (presently
three years) for the
                                       F-9
<PAGE>
              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

nonrecoverable portion of such costs. The nonrecoverable portion of the cost of
a wireless cable installation becomes fully depreciated upon disconnection of
the subscriber. Prior to 2001, the Company capitalized only the excess of
nonrecoverable costs of subscriber installations over installation revenues. The
Company revised its accounting for wireless cable nonrecoverable installation
costs prospectively, effective January 1, 2001, to discontinue the netting of
installation revenues against nonrecoverable costs of subscriber installations.

     In the fourth quarter of 2001, Nucentrix wrote down the value of its
systems and equipment to fair market value (estimated by management) in
accordance with SFAS No. 121 (see note 2). The re-valued systems and equipment
will be amortized over the average remaining life of 12 months.

  (i) LICENSE AND LEASED LICENSE INVESTMENT

     License and leased license investment includes costs incurred to acquire
and/or develop MMDS and ITFS spectrum rights and are amortized on a
straight-line basis over 15 years beginning with inception of service in each
market since Fresh Start and 12.5 years for those markets that existed at Fresh
Start (see note 4).

     In the fourth quarter of 2001, Nucentrix wrote down the value of its
license and leased license investment assets to estimated fair market value in
accordance with SFAS No. 121 (see note 2). The re-valued license and leased
license investment assets will be amortized over the average remaining life of
10 years.

  (j) REVENUE RECOGNITION

     Revenues currently consist primarily of monthly fees paid by wireless cable
subscribers for basic programming, premium programming, equipment rental, and
other miscellaneous fees, and revenues from the Company's agency relationship
with DIRECTV. Revenues also include fees generated from Internet operations in
Austin and Sherman-Denison, Texas. Unless the context requires otherwise, all
references to "subscribers" or "systems" are to wireless cable subscribers and
systems because revenues and subscribers from the Company's Internet business
were approximately 1% of consolidated revenues in 2001.

     Subscription revenues from wireless cable subscribers and continuing
monthly service fees from DIRECTV for each DIRECTV customer generated are
recognized as service is provided. If the Company does not meet minimum
subscriber benchmarks each year, the DIRECTV continuing service fee will be
reduced.

     Effective January 1, 2001, wireless cable and DIRECTV installation revenue
and revenue received from the Company's agency relationship with DIRECTV (except
for continuing monthly service fees, which are recognized as received), is
recognized to the extent of direct selling costs incurred, and the remainder is
deferred and amortized to income over the expected subscriber relationship
period of three years. A chargeback reserve is recorded for all DIRECTV
contingencies. Prior to 2001, wireless cable installation revenue was offset
against the nonrecoverable portion of installation costs, with the excess cost
capitalized and amortized to depreciation expense over the expected subscriber
relationship period of three years. Prior to 2001, DIRECTV installation revenue
(cash received directly from the customer in conjunction with the sale) was
offset against direct incremental costs, with the resulting amount recorded as a
net asset. This asset, referred to as "subscriber acquisition costs," was
amortized as a component of selling, general and administrative ("SG&A") expense
in proportion to the revenues projected to be generated over the expected
subscriber relationship period. Revenue from the agency relationship with
DIRECTV (other than monthly service fees) was recognized as the contingencies
related to each revenue component were resolved. A chargeback reserve was not
recorded for canceled subscribers. The Company revised its accounting for
wireless cable installation and DIRECTV revenues prospectively, effective
January 1, 2001, as discussed above.

              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  (k) INCOME TAXES

     Nucentrix utilizes the asset and liability method for accounting for
deferred income taxes. Under this method, deferred tax assets and liabilities
are recognized for the future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax bases and operating loss and tax credit
carryforwards. Deferred tax assets and liabilities are measured using enacted
tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
the period that includes the enactment date. Valuation allowances are
established when necessary to reduce deferred tax assets to the amount expected
to be realized. Based on the foregoing policy, deferred tax assets net of
deferred tax liabilities have been fully reserved.

  (l) NET LOSS PER COMMON SHARE -- BASIC AND DILUTED

     The Company has presented basic and diluted loss per share, computed on the
basis of the weighted average number of common shares outstanding during the
period. Outstanding options to purchase 796,100 and 902,700 shares of common
stock at December 31, 2001 and 2000, respectively, and outstanding warrants to
purchase 825,000 shares of common stock at December 31, 2001 and 2000, were not
included in the computation of diluted loss per share because their effects are
antidilutive. Earnings per share information has not been presented for the
Predecessor Period as the Company was recapitalized on the Effective Date in
connection with the Plan and, accordingly, per share amounts are not comparable
between the Predecessor and Successor Periods.

  (m) USE OF ESTIMATES

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

  (n) CONCENTRATIONS OF CREDIT RISK AND ACCOUNTS RECEIVABLE

     Nucentrix's subscribers and the related accounts receivable are primarily
residential subscribers that are concentrated in eight states across Texas,
Oklahoma and the Midwestern United States. Nucentrix establishes an allowance
for doubtful accounts based upon factors surrounding the credit risk of specific
subscribers, historical trends and other information.

  (o) OTHER ASSETS

     Other assets at December 31, 2001 principally include purchased software
and subscriber acquisition costs, and at December 31, 2000, principally include
excess reorganization value, purchased software and subscriber acquisition
costs. Subscriber acquisition costs consist of the direct incremental costs
incurred in generating a customer relationship with DIRECTV (materials,
equipment and labor). Subscriber acquisition costs are amortized as a component
of SG&A expense over the expected customer relationship period of three years.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  (p) RECLASSIFICATIONS

     Certain prior year balances have been reclassified to conform to the
current year presentation.

  (q) STOCK-BASED COMPENSATION

     The Company accounts for its stock-based employee compensation plan using
the intrinsic value-based method prescribed by Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No. 25") and
related interpretations. As such, compensation expense is recorded on the date
of grant to the extent the current market price of the underlying stock exceeds
the exercise price. The Company has provided pro forma disclosures as if the
fair value-based method of accounting for these plans, as prescribed by SFAS No.
123, "Accounting for Stock-Based Compensation," had been applied (see note 9).

  (r) COMPREHENSIVE INCOME

     Comprehensive income includes net income and other comprehensive income
which is generally comprised of changes in the fair value of available-for-sale
marketable securities, foreign currency translation adjustments and adjustments
to recognize additional minimum pension liabilities. For all periods presented,
comprehensive income (loss) and net income (loss) are the same amount.

  (s) SEGMENT REPORTING

     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," requires that public companies report operating segments based
upon how management allocates resources and assesses performance. Based on the
criteria outlined in SFAS No. 131, Nucentrix was comprised of two reportable
segments at the end of 2001: (i) distribution of wireless cable services, and
(ii) delivery of IP-based services (see note 15).

(2) IMPAIRMENT OF LONG-LIVED ASSETS

     In the fourth quarter of 2001, the Company reviewed its systems and
equipment, and license and leased license investment assets for impairment in
accordance with the requirements of SFAS No. 121. Events and circumstances that
the Company considered as impairment indicators included (i) the expected
conversion of substantially all of its wireless cable subscribers to satellite
and cable programming provided by other companies, (ii) the need to continue
evaluating the development of technology for MMDS service which likely would
delay deployment of new Internet markets beyond 2002, and (iii) the
uncertainties associated with raising capital required to implement the
Company's long-term business plan.

     In determining whether an impairment was required for systems and
equipment, the Company examined the future cash flows expected to be generated
from these assets and the amount that management estimated could be realized for
these assets in an orderly disposition, if required, and compared this amount to
the carrying amount of the assets. In analyzing its license and leased license
investment assets, the Company retained the services of a third party to provide
a fair market valuation. Based on this analysis, the Company determined that a
non-cash impairment charge in 2001 of $14.1 million was required, as follows:

<Table>
<S>                                                            <C>

     Although the third party market valuation of the Company's aggregate
license and leased license investment was substantially in excess of the
Company's aggregate carrying amount, as required by SFAS

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

No. 121 the Company examined these assets on an individual market basis and
determined that the carrying amount, related to ten markets should be written
down in the total amount of $9.4 million.

     The Company's estimates of future gross revenues and operating cash flows,
the remaining estimated lives of long-lived assets, or both could be reduced in
the future due to changes in, among other things, technology, government
regulation, available financing, or competition. As a result, the carrying
amounts of long-lived assets could be reduced by additional amounts which would
be material to the Company's financial position and results of operations.

(3) SYSTEMS AND EQUIPMENT

     Systems and equipment consists of the following at December 31, 2001 and
2000:

</Table>

     See note 2 for discussion of systems and equipment write-down in the fourth
quarter of 2001.

     In the fourth quarter of 1999, Nucentrix sold 30 of its communication
towers to SBA Towers, Inc. ("SBA Towers") for approximately $6.2 million in a
transaction accounted for as a sale-leaseback (see note 6). This transaction
resulted in a deferred gain of approximately $3.8 million. The sale of four
additional tower sites was closed in the second and third quarters of 2000 for
approximately $830,000, resulting in a deferred gain of approximately $450,000.
During the years ended December 31, 2001 and 2000, $417,000 and $400,000,
respectively, of the total $4.2 million gain was recognized as other income. The
remaining deferred gain is included in other long-term liabilities (long-term
portion) and accrued liabilities (current portion) on the accompanying
consolidated balance sheet as of December 31, 2001.

(4) FCC LICENSES AND OPERATING LEASES

     License and leased license investment consists primarily of costs incurred
in connection with the Company's acquisition and development of FCC spectrum
rights. Spectrum rights represent the right to utilize all of the capacity on
spectrum operated under a license received from the FCC. These assets are
recorded at cost and amortized using the straight line method over the assets'
estimated useful lives. Accumulated amortization on license and leased license
investment was $22.1 million and $15.2 million at December 31, 2001 and 2000,
respectively. Additions to license and leased license investment of $5.2 million
and $3.2 million during 2001 and 2000, respectively, consisted of engineering
and other costs related to the preparation and filing of applications with the
FCC for two-way use of the Company's spectrum, as well as the cost to acquire
new licenses in several markets. See note 2 for discussion of license and leased
license investment write-down in the fourth quarter of 2001.

     Nucentrix depends on leases with third parties for some of its spectrum
rights. FCC licenses generally must be renewed every 10 years. All licenses are
subject to renewal by the FCC. Although FCC custom and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

practice establish a presumption of granting renewals of licenses, the
presumption requires that the licensee substantially comply with its regulatory
obligations during the license period.

     Spectrum lease agreements generally require payments based on the greater
of specified minimums or amounts based upon subscriber levels or revenues.
Spectrum lease payments generally begin upon the completion of construction of
transmission equipment and facilities and upon approval for operation under FCC
rules. For certain leases, payments begin upon grant of the spectrum rights.
Spectrum lease expense was $3.6 million, $3.5 million, $900,000, and $2.7
million for the years ended December 31, 2001 and 2000, the period from January
1, 1999, to the Effective Date, and the period from the Effective Date to
December 31, 1999, respectively.

     Nucentrix also has other operating leases for office space, vehicles,
equipment, and transmission tower space. Rent expense incurred in connection
with these leases was $2.8 million, $2.6 million, $1 million, and $2.7 million
for the years ended December 31, 2001 and 2000, the period from January 1, 1999,
to the Effective Date, and the period from the Effective Date to December 31,
1999, respectively.

     Future minimum lease payments due under noncancellable leases at December
31, 2001, are as follows:

     In December 1999, Nucentrix entered into capital lease agreements with SBA
Towers to lease back space on 34 towers that Nucentrix sold to SBA Towers in
1999 and 2000 (see note 3). A lease obligation of $2.2 million was recorded in
connection with the lease of 30 of the towers as of December 31, 1999, and an
additional obligation of $294,000 was recorded when the sale of the four
remaining towers closed during 2000. These capital lease obligations have an
initial term of 10 years, with three (3) five-year renewal options. The Company
also leases computer and office equipment under capital leases, with remaining
terms of less than one year.

     Other notes payable at December 31, 2001 and 2000, relate to the
acquisition of BTAs from the FCC. The note payable to the FCC bears interest at
9.5%, payable quarterly over ten years beginning November 1996. Quarterly
principal payments are payable over the remaining eight years beginning November
1998.

     Nucentrix and CS Wireless Systems, Inc. ("CS Wireless") entered into a
lease and purchase option agreement for certain spectrum rights associated with
the BTAs (collectively, the "Leased BTAs") awarded to Nucentrix at a total cost
of approximately $5.2 million. Under this agreement, CS Wireless reimburses
Nucentrix for principal and interest paid to the FCC for the Leased BTAs. As of
December 31, 2001 and 2000, the amount of FCC debt related to the Leased BTAs
totaled $2.0 million (net of current portion of $400,000), and $2.4 million (net
of current portion of $400,000), respectively, and CS Wireless' obligation to
the Company has been recorded as a receivable.

     Aggregate maturities of long-term debt and capital lease obligations as of
December 31, 2001, for the five years ending December 31, 2006, are as follows:
2002 -- $2.4 million; 2003 -- $2.1 million; 2004 -- $2.4 million; 2005 -- $2.6
million; and 2006 -- $2.2 million.

  DEBT CANCELLATION UNDER THE PLAN

     On April 1, 1999, under the terms of the Plan, the Old 13% Notes, Old 14%
Notes and Old Convertible Notes were canceled. The holders of the Old Senior
Notes and Old Convertible Notes received 9,700,000 and 300,000 shares,
respectively, of newly issued common stock in exchange for cancellation of their
debt. The holders of the Old Convertible Notes also received warrants to
purchase 825,000 shares of newly issued common stock. As of December 4, 1998,
Nucentrix discontinued the accrual of interest and amortization of deferred debt
issuance costs and discounts on notes payable related to Liabilities Subject to
Compromise. If interest had continued to be accrued, total interest expense
would have been $12.6 million for the period from January 1, 1999, to the
Effective Date.

(8) ACQUISITIONS/DISPOSITIONS

     Fayetteville and Fort Smith, Arkansas Acquisition.  In April 2001, the
Company completed the purchase of certain of the MMDS spectrum licenses, leases
and related assets of Smithco of Ft. Smith, Inc. and Smithco Investments of West
Memphis, Inc., in Fort Smith, Arkansas in exchange for the issuance of
approximately 153,000 shares of common stock of the Company, valued at $4.2
million as of the date of filing of the Company's Form 10-Q for the first
quarter of 2001, in which the Company initially announced this transaction. The
153,000 shares of common stock includes up to approximately 16,000 shares
issuable over two years. In addition, the Company entered into new MDS spectrum
leases for three channels (18 MHz) in Fort Smith and new ITFS spectrum leases
for 20 channels (120 MHz) in each of Fort Smith and Fayetteville, Arkansas. The
Company also assumed a lease and purchase agreement for four MMDS channels (24
MHz) in Fort Smith the provides for the payment of $337,000 in cash through
September 2002.

     Rockford, Illinois Acquisition.  In May 2000, the Company entered into a
definitive agreement to acquire all of the MDS, MMDS and ITFS spectrum licenses,
lease rights and other assets of Wireless Cable of Rockford, LLC and Allen Leeds
in Rockford, Illinois. In October 2001, the FCC dismissed the BTA owner's
application for consent to assign the Rockford BTA to the Company. As a result,
the Company or the BTA owner may terminate the purchase agreement, or the
parties may determine to modify the agreement. In November 2001, the BTA owner
filed a Petition for Reconsideration of the FCC's decision. If the parties
determine to proceed, the transaction will be subject to other customary closing
conditions including due diligence.

     Exchange of Equity Interest in Wireless One, Inc.  In January 2000, the
Company exchanged 2,911,725 shares of common stock in Wireless One, Inc.
("Wireless One") for approximately $3.8 million, pursuant to Wireless One's plan
of reorganization under Chapter 11 of the Bankruptcy Code. In July 2000, an
additional 547,783 shares of common stock in Wireless One was exchanged for
approximately $700,000. After these transactions, Nucentrix retained no equity
interest in Wireless One. Losses recorded in prior years for Wireless One had
reduced the carrying amount of the Company's investment to zero. Accordingly,
the proceeds have been classified as a gain on sale of assets and included in
other income in the consolidated statement of operations for the year ended
December 31, 2000.

</Table>

     The net changes in the total valuation allowance for the years ended
December 31, 2001, and 2000, the periods from the Effective Date to December 31,
1999 and from January 1, 1999, to the Effective Date, were increases (decreases)
of $17.5 million, ($62.4) million, $8.9 million, and $2.6 million, respectively.
In assessing the realizability of deferred tax assets, Nucentrix considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets
depends on the generation of future taxable income during the periods in which
the temporary differences become deductible. Nucentrix considers the scheduled
reversal of deferred tax liabilities, projected future taxable income, and tax
planning strategies in making this assessment. Based upon these considerations,
Nucentrix has fully reserved all deferred tax assets to the extent that such
assets exceed deferred tax liabilities.

     As a result of the cancellation of the Old Senior Notes, Old Convertible
Notes and common stock outstanding at the Effective Date, and the issuance of
new shares of common stock and warrants in accordance with the Plan, federal tax
law requires that the amount of income from discharge of indebtedness

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

that occurs in connection with a Chapter 11 bankruptcy be used to permanently
reduce federal tax attributes. These reductions may be applied to one or more
tax items, including but not limited to pre-bankruptcy net operating loss
carryforwards, the tax basis of certain assets and the tax basis of subsidiary
stock. Management has elected to apply the required reduction first to tax basis
in depreciable assets, and then to net operating loss carryforwards. The amount
of reduction in the tax basis of depreciable assets was approximately $56
million. The amount of reduction in net operating loss carryforwards was
approximately $118 million, leaving approximately $222 million in remaining net
operating loss carryforwards at December 31, 2000. The net operating loss
carryforwards at December 31, 2001 are $261 million and expire in years 2013
through 2020. Nucentrix estimates that approximately $38 million of the
carryforwards at December 31, 2001 relate to various acquisitions and are
subject to certain limitations.

     In addition to the permanent Tax Attribute Reduction, the Company also must
limit the annual deduction of pre-bankruptcy net operating losses and "built-in
deductions" to an amount no greater than the fair market value of the Company
immediately after the restructuring, multiplied by the long-term tax exempt
rate. This annual limitation is currently estimated to be approximately $7.3
million.

(11) BENEFIT PLAN

     The Company sponsors a 401(k) savings plan in which substantially all
employees are eligible to participate upon completion of six months of service.
The plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974, as amended. The plan permits eligible employees to contribute up to
20% of their compensation, subject to the annual maximum allowed by the Internal
Revenue Service. The Company may make discretionary matching contributions to
the plan. The Company began making discretionary matching contributions to the
plan for the 2001 plan year on April 1, 2001, and contributed $113,000 during
the year ended December 31, 2001. No discretionary matching contributions were
made by the Company during the year ended December 31, 2000, for the period from
the Effective Date to December 31, 1999, or for the period from January 1, 1999,
to the Effective Date.

(12) RELATED PARTY TRANSACTION

     During 1999, Nucentrix leased office space from entities owned by certain
former officers and directors of Nucentrix for which the expense amounted to
approximately $19,000 for the period from January 1, 1999, to the Effective
Date, $58,000 for the period from the Effective Date to December 31, 1999. In
connection with its restructuring, Nucentrix terminated approximately 56,000
square feet of such leases. The Company then terminated all of these remaining
leases in November 1999.

(13) COMMITMENTS AND CONTINGENCIES

     Securities Litigation.  Nucentrix and certain of its former officers and
directors were co-defendants in a stockholder action originally filed in
February 1998 in the United States District Court for the Northern District of
Texas, styled Coates, et al. v. Heartland Wireless Communications, Inc., et al.
(3-98-CV-0452-D). The Coates action involved federal securities laws claims
brought by two former stockholders of Heartland against Heartland and six former
officers and/or directors. In June 2000, the court dismissed the plaintiffs'
complaint with prejudice. The plaintiffs appealed the dismissal to the U.S.
Court of Appeals for the Fifth Circuit. In addition, three of the Company's
former officers and directors were co-defendants in a purported class action
lawsuit originally filed in July 1998 in State District Court in Kleburg County,
Texas, styled Thompson, et al. v. David E. Webb, et al. (98-371-D). Plaintiffs
in the Thompson action alleged state securities laws violations,
misrepresentation and civil conspiracy claims.

     In 2001, the parties in the Coates and Thompson lawsuits executed
settlement agreements for the respective lawsuits. In January 2002, the court in
Thompson approved the settlement and entered a Final Judgment and Order of
Dismissal with prejudice in this matter. In March 2002, the Court of Appeals in
                                       F-20
<PAGE>
              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Coates dismissed the appeal pursuant to the settlement agreement entered into in
that lawsuit. All amounts payable by the defendants in the settlement of both
the Coates and Thompson lawsuits will be covered by the proceeds from the
Company's primary directors and officers liability insurance policy.
Accordingly, this settlement will not have a material adverse effect on the
consolidated financial condition, results of operations or cash flows of the
Company.

     Other Litigation.  Nucentrix and certain officers and directors of
Nucentrix are parties to several purported class action lawsuits relating to
administrative late fees, alleged breach of various consumer lease and credit
laws and alleged breach of Federal notice and privacy statutes. All of these
lawsuits were filed by the same plaintiff's attorney in various state and
federal courts in Texas, as follows:

     - Garcia, et al. v. Heartland Wireless Communications, Inc. d/b/a Heartland
       Cable Television (98-60898-1), filed in May 1998 and pending in the 79th
       Judicial District Court in Brooks County, Texas (dismissed and appealed),

     - John Nolen, Jr., et al. v. Nucentrix Broadband Networks, Inc.
       (DC-00-155), filed in May 2000 and pending in the 229th Judicial District
       Court in Duval County, Texas,

     - Nolen, et al. v. Nucentrix Broadband Networks, Inc., et al. (L-00CV134),
       filed in October 2000 in U.S. District Court for the Southern District of
       Texas, Laredo Division (dismissed and appealed),

     - Perez, et al. v. Nucentrix Broadband Networks, Inc.(01-141-D), filed in
       March 2001 and pending in the 105th Judicial District Court in Kleberg
       County, Texas,

     - Garcia v. Heartland Wireless Communications, Inc.(01-04-10449CV), filed
       in April 2001 in the 79th Judicial District Court in Brooks County, Texas
       (dismissed and appealed),

     - Torres v. Nucentrix Broadband Networks, Inc.  (01-61022-1), filed in
       September 2001 and pending in County Court at Law No. 1 in Nueces County,
       Texas,

     - Santellana v. Nucentrix Broadband Networks, Inc.(S-01-6109-CV-B), filed
       in November 2001 and pending in the 156th Judicial District Court in San
       Patricio County, Texas (dismissed),

     - Ysasi and Garcia v. Nucentrix Broadband Networks, Inc., DIRECTV, Inc., et
       al. (C-02-001), filed in January 2002 in U.S. District Court for the
       Southern District of Texas, Corpus Christi Division (dismissed), and

     - Santellana v. Nucentrix Broadband Networks, Inc. and DIRECTV, Inc.
       (C-02-079), filed in February 2002 and pending in U.S. District Court for
       the Southern District of Texas, Corpus Christi Division.

     These lawsuits generally allege that administrative late fees charged by
Nucentrix are unenforceable and/or usurious. The lawsuits generally seek to
certify a class to represent all persons who have entered into wireless cable
service agreements with Nucentrix or who have paid an administrative late fee to
Nucentrix, and seek a declaration that any contractual provisions for
Nucentrix's administrative late fees are usurious and/or unenforceable as a
penalty, money damages, interest, attorneys' fees, and costs.

     In addition, the Nolen lawsuit filed in the Southern District of Texas
alleges violation of the federal Racketeering Influenced and Corrupt
Organizations Act ("RICO"). The Nolen action alleges that Nucentrix and other
defendants together caused the collection of an unlawful debt comprised of a
service fee for subscription television services and an administrative late fee,
in violation of RICO. The plaintiff in Nolen seeks disgorgement and payment of
unspecified restitution to members of the purported class, as well as treble
damages, attorneys' fees, interest and costs.

     Furthermore, the Ysasi and Garcia action and first Santellana lawsuit noted
above allege breach of several federal and state statutes relating to consumer
lease and credit transactions, including the Consumer Leasing Act, Truth in
Lending Act, Magnuson-Moss Warranty Act, and the Texas Business and Commerce
                                       F-21
<PAGE>
              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Code. The plaintiffs in these matters seek statutory, compensatory and punitive
damages, as well as attorneys' fees, costs and interest. Finally, the second
Santellana lawsuit noted above alleges breach of notice and privacy provisions
of the Cable Television Consumer Protection and Competition Act by Nucentrix and
DIRECTV.

     The Company believes the above actions to be without merit and intends to
vigorously defend them. The initial Garcia lawsuit and the second Nolen lawsuit
noted above have been dismissed by the U.S. Bankruptcy Court for the District of
Delaware and the U.S. District Court for the Southern District of Texas,
respectively. The plaintiffs have appealed these decisions. In March 2002, the
courts in the second Garcia lawsuit and in the initial Santellana lawsuit
granted the Company's Motion to Compel Arbitration and dismissed these lawsuits.
The plaintiff in Garcia has filed a notice of appeal. In April 2002, the U.S.
District Court for the Southern District of Texas dismissed the federal claims
in the Ysasi and Garcia lawsuit with prejudice, and dismissal the state law
claims (which were supplemental to the federal claims) without prejudice. In
addition, Texas courts in Nueces and San Patricio counties have dismissed two
similar late fee lawsuits filed by the same plaintiff's attorney against the
Company, with no appeal. While it is not feasible to predict or determine the
final outcome of these proceedings or to estimate the amounts or potential range
of loss with respect to these matters, and while management does not expect such
an adverse outcome, management believes that an adverse outcome in one or more
of these proceedings could have a material adverse effect on the Company's
financial condition, results of operations or cash flows.

     State Court Action.  In December 2000, several former stockholders of
Heartland filed a lawsuit against certain of the Company's current and former
directors and officers, and former holders of Old Senior Notes, styled Hunt
Capital Group, L.L.C., et al., v. Carroll D. McHenry, et al., Case No.
OJ-2000-534 in the District Court for Bryan County, Oklahoma. The plaintiffs
allege that the defendants purposely undervalued the Company's enterprise value
as part of the Plan confirmation process in order to extinguish all prepetition
equity holders' interests. The plaintiffs seek unspecified damages in excess of
$10,000 on behalf of all prepetition stockholders of Heartland, under theories
of fraud, negligent misrepresentation, unjust enrichment, breach of fiduciary
duty, and constructive trust.

     In February 2001, certain of the defendants removed this lawsuit to the
U.S. District Court for the Eastern District of Oklahoma, which was subsequently
assigned Civil Action No. 01-095-S. The defendants concurrently sought transfer
of venue from the Eastern District of Oklahoma to the U.S. District Court for
the District of Delaware and, in April 2001, the U.S. District Court for the
Eastern District of Oklahoma granted the defendants' motion to transfer venue to
U.S. District Court of Delaware. In addition, in February 2001 the Company
filed, in the U.S. Bankruptcy Court for the District of Delaware, an Emergency
Motion to Enforce Plan of Reorganization and Confirmation Order, seeking to
enjoin and prevent the state court action from proceeding as a violation of the
terms of the Company's Plan. In June 2001, the Bankruptcy Court granted the
Company's motion and ordered that the plaintiffs dismiss the lawsuit with
prejudice. Plaintiffs have appealed this decision to the U.S. District Court for
the District of Delaware. The appeal is pending.

     The Company may have certain indemnity obligations to the director and
officer defendants in the Hunt Capital matter. The Company believes the
allegations to be without merit and intend to vigorously defend this action on
behalf of the director and officer defendants.

     Asset Purchases.  In April 2001 the Company completed the purchase of
certain of the MMDS spectrum licenses, leases and related assets of Smithco of
Ft. Smith, Inc. and Smithco Investments of West Memphis, Inc. in Fort Smith,
Arkansas in exchange for the issuance of approximately 153,000 shares of common
stock of the Company, valued at $4.2 million as of the date of filing of the
Company's Form 10-Q for the first quarter of 2001, in which the Company
initially announced this transaction. The 153,000 shares of common stock
includes up to approximately 16,000 shares issuable over two years. In addition,
the Company entered into new MDS spectrum leases for three channels (18 MHz) in
Fort Smith and new ITFS spectrum leases for 20 channels (120 MHz) in each of
Fort Smith and Fayetteville, Arkansas. The Company also

                                       F-22
<PAGE>
              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

assumed a lease and purchase agreement for four MMDS channels (24 MHz) in Fort
Smith that provides for the payment of $337,000 in cash through September 2002.

     In May 2000, the Company entered into a definitive agreement to acquire all
of the MMDS and ITFS spectrum licenses, lease rights and other assets of
Wireless Cable of Rockford, LLC and Allen Leeds in Rockford, Illinois. In
October 2001, the FCC dismissed the BTA owner's application for consent to
assign the Rockford BTA to the Company. As a result, the Company or the BTA
owner may terminate the purchase agreement, or the parties may determine to
modify the agreement. In November 2001, the BTA owner filed a Petition for
Reconsideration of the FCC's decision. If the parties determine to proceed, the
transaction will be subject to other customary closing conditions, including due
diligence.

     Spectrum Allocation Proceedings for Advanced Wireless Services.  In the
fourth quarter of 2000, the FCC and other government organizations initiated
proceedings to study, identify and authorize additional radio frequencies for
advanced wireless services, including 3G mobile wireless services. Several
frequency bands were studied in this process. One of the frequency bands under
consideration for such services was the 2.5 GHz band, in which the Company holds
substantially all of its MMDS and ITFS FCC licenses and spectrum leases. In
September 2001, the FCC adopted an order not to relocate incumbent license
holders and operators in the 2.5 GHz band, such as Nucentrix, to other frequency
bands. The FCC also added a flexible use allocation to the 2.5 GHz band, making
this band available for advanced mobile services, including 3G wireless systems.
The flexible use allocation is subject to the protection of existing fixed
wireless licenses in the 2.5 GHz band from interference.

     The 2.1 GHz band, however, remains under consideration by the FCC for
relocation for 3G services. The Company currently uses the 2.1 GHz band for
upstream transmissions in its existing networks, and the 2.1 GHz band is part of
the Company's plan for future networks. The Company could be required to
relocate current and future broadband wireless services in the 2.1 GHz band to
another frequency band. The Company is not able to determine at this time the
impact that relocation would have on its operations; however, relocation of
operations to another frequency band could require new or additional equipment,
raise operating costs, delay the provision of service, or render service
uneconomic in certain areas.

     Other.  The Company also is a party to other legal and regulatory
proceedings, a majority of which are incidental to its business. In the opinion
of management, and after consideration for amounts recorded in the accompanying
consolidated financial statements, the ultimate effects of such other matters
are not expected to have a material adverse effect on the consolidated financial
condition, results of operations or cash flows of the Company.

(14) FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following table presents the carrying amounts and estimated fair value
of Nucentrix's financial instruments at December 31, 2001 and 2000. The fair
value of a financial instrument is defined as the amount at which the instrument
could be exchanged in a current transaction between willing parties:

Long-term debt.................................   10,569     10,569    12,199     12,199
</Table>

     The fair value of cash and cash equivalents, accounts receivable and
accounts payable approximate the carrying amounts of these assets and
liabilities because of the short maturity of these instruments.

<PAGE>
              NUCENTRIX BROADBAND NETWORKS, INC. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The carrying value of bank certificates of deposit approximates fair value
since the term of the underlying deposits is short-term at the reporting date.
The carrying amount of note receivable from affiliate approximates fair value
since the interest rate (9.5% at December 31, 2001) equates to the market rate
of interest. The fair value of the long-term debt is based on management's
estimates derived from current rates offered for similar borrowings.

(15) SEGMENT REPORTING

     Historically, the Company has been considered to have a single reportable
segment: the distribution of subscription television, or "wireless cable,"
services. However, based on the Company's long-term business strategy to provide
broadband wireless services in its markets, the Company is considered to be
comprised of two reportable segments: (i) distribution of wireless cable
services and (ii) delivery of IP-based services. The Company measures segment
profit as EBITDA. EBITDA is defined as earnings before interest, taxes,
depreciation, amortization, and non-recurring items. Information regarding
operating segments as of and for the years ended December 31, 2001, 2000 and
1999, is presented in the following tables. For comparison purposes, references
to the year ended December 31, 1999, represent the combined amounts for the
period of January 1, 1999, through the Effective Date and the period from the
Effective Date through December 31, 1999.

(A)  Revenues from the wireless cable services segment's agency relationship
     with DIRECTV represent approximately $2.1 million, $6.3 million, and $4.3
     million of the Company's consolidated revenue for the years ended December
     31, 2001, 2000 and 1999, respectively.

(B)  Intersegment revenue (expense) represents a charge from the IP-based
     services segment to the wireless cable services segment for the use of
     shared assets. The "other" category includes corporate expenses, other
     income and assets not considered part of the two reportable segments.

(C)  EBITDA.  EBITDA, or earnings before interest, taxes, depreciation,
     amortization, and non-recurring items, is widely used by analysts,
     investors and other interested parties in the Internet, cable television
     and telecommunication industries. EBITDA is also widely accepted as a
     financial indicator of a company's ability to incur and service
     indebtedness. EBITDA is not a financial measure determined by generally
     accepted accounting principles and should not be considered an alternative
     to net income as a measure of operating results or to cash flows as a
     measure of funds available for discretionary or other liquidity purposes.
     EBITDA may not be comparably calculated from one company to another.
