ITEM 1. BUSINESS
 
THE COMPANY
 
    National Wireless Holdings Inc. ("NWH" or the "Company"), a Delaware
corporation organized on August 31, 1993, is a holding and strategic resource
company for telecommunications and other businesses. The Company currently
operates an electronic data interchange company, providing links between
healthcare providers and third party payors. In addition, the Company operates a
satellite programming uplink facility, an educational programming distribution
company and other early stage businesses. The Company also seeks to support,
finance and acquire new businesses and technologies in the telecommunications
and other industries. The Company recently acquired an interest in a company
organized to purchase a British telecommunications company, and may acquire or
invest in other businesses.
 
    In June 1997, the Company sold its wireless cable assets in Miami Florida in
exchange for $48 million of common stock of BellSouth Corporation.
 
    On September 10, 1997, the Company acquired additional shares of Electronic
Data Submission Systems, Inc. ("EDSS") from a stockholder, which when combined
with its existing share ownership represents 55% of the outstanding common stock
and control of EDSS. The Company acquired its interest in EDSS first as a lender
and then through exercise of a warrant and an option to purchase shares of EDSS
common stock.
 
    The Company's executive offices are located at 249 Royal Palm Way, Suite
301, Palm Beach, Florida 33480, telephone: (407) 822-9933.
 
ELECTRONIC DATA INTERCHANGE
 
    -- GENERAL
 
    NWH owns 55% of the capital stock of and manages EDSS. EDSS provides
electronic data interchange ("EDI") services and healthcare information
management services to the healthcare market. The market includes physicians,
hospitals, clinics, billing services, commercial insurance companies, managed
care organizations, preferred provider organizations, state and federal
governmental agencies and others (collectively, "Payors"). EDSS provides
healthcare EDI services on a real-time and batch-processing basis by utilizing
its proprietary software HECET Systems-Registered Trademark-. This software
allows medical providers and Payors to communicate electronically the
information needed to process and expedite the payment of insurance claims,
physician referrals and insurance authorizations. HECET
Systems-Registered Trademark- will also check patient eligibility and provide
comprehensive reporting on those claims. The EDSS private transaction network is
directly connected to over 4,000 physicians, and has direct or gateway access to
540 Payors.
 
    EDSS was incorporated in Colorado on January 7, 1991 and was reincorporated
in Delaware on September 10, 1997.
 
    -- INDUSTRY BACKGROUND
 
    The rapid expansion of the healthcare industry over the last decades led to
a significant increase in the number of claims and the complexity of the
processing of claims for reimbursement by Payors. These claims are still largely
processed on paper, a cumbersome, costly and inaccurate method. Recent advances
in computer software, telecommunications and microprocessor technology
facilitate the development of on-line, real-time systems that electronically
capture and transmit information, replacing the recording and processing of
transaction information on paper. In addition to offering greater convenience,
these electronic systems reduce processing costs, settlement delays and losses
from fraudulent transactions.
 
                                       3
<PAGE>
    Health care providers initiate electronic transaction processing through
dedicated point-of-service terminals, stand-alone software or software
integrated with the provider's management information system. The submission of
claims occurs by providers aggregating and editing claims throughout the day at
the provider's office and submitting them electronically to EDSS or its
competitors in batch. Claims are sorted, formatted and edited a second time by
EDSS or its competitors and are then forwarded electronically to the Payor. The
claim is processed by the Payor and the adjudicated response is transmitted back
to the provider. To the extent required, the Payor then sends a check to the
provider or, in certain circumstances, initiates an electronic funds transfer to
the provider's account.
 
    EDSS believes EDI transaction processing offers a number of benefits to
Payors and providers. The elimination or reduction of paper-based transactions
significantly lowers claims processing costs of Payors, and on-line encounter
and referral information provides more efficient medical cost management for
managed care organizations. In addition, Payors are able to more easily detect
fraud and screen for unusual utilization trends. Errors in transcriptions by
Payor examiners are virtually eliminated. From the health care providers'
standpoint, information pertaining to authorization and reimbursement can be
more easily accessed and transmitted. By processing claims electronically,
providers also reduce overhead costs and staff time and improve accounts
receivable management.
 
    The recent growth of managed care and governmental health care cost
containment efforts have increased the use of real time transaction processing
by hospitals and physicians. Certain state Medicaid programs permit providers to
electronically verify Medicaid eligibility on a real-time basis, and certain
managed care companies have encouraged their provider networks to utilize
real-time EDI for authorizations, encounter reports and referrals. EDSS believes
that there are significant opportunities for further expansion of EDI
transactions to the health care market, for claims processing, as performed
currently, for managed care client identification, for clinical and for other
purposes.
 
    -- BUSINESS STRATEGY
 
    EDSS's strategy is to grow as a provider of EDI services in the healthcare
market by expanding the number of markets it serves and broadening the EDI
services provided. The key elements of this strategy include:
 
    - CONTINUE TO DEVELOP MARKETING AT THE PROVIDER LEVEL. EDSS intends to
      expand business through aggressive marketing at the provider level with
      its user friendly HECET Systems-Registered Trademark-. By installing its
      own software product, HECET Systems-Registered Trademark-, EDSS maintains
      a competitive advantage via direct relationships with each individual
      physician or other health service provider's office. The vast majority of
      present market connectivity emanates from systems vendors that forward the
      transactions to a clearinghouse. The direct site connectivity created by
      HECET Systems-Registered Trademark- affords EDSS a quick and easy way to
      add EDI functionality to its client's offices while also providing
      technical interfaces to its installed system environment. HECET
      Systems-Registered Trademark- provides an installed proprietary software
      presence for EDSS, thereby reducing the likelihood that its services will
      be replaced with a competing product or service. EDSS provides flexible
      formatting and mapping capabilities matching current hardware and software
      used by or available to providers. With a broader base of providers, EDSS
      expects to expand its network of Payers serviced.
 
    - EXPAND INTO ADDITIONAL MARKETS. In pursuit of greater market share, EDSS
      plans to expand beyond its current operations in Colorado, Florida, Texas,
      and Illinois by opening offices in the tri-state area of New York/New
      Jersey/Connecticut and other densely populated areas throughout the
      country. In addition, EDSS will pursue an aggressive program to capture
      high transaction volume systems vendors, billing services and the new
      breed of internet claims aggregators. Both the current claims mining and
      after-market sales activities will also be expanded to maximize revenues,
      from each installed site.
 
                                       4
<PAGE>
    - PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES. EDSS will seek acquisitions
      of or alliances with other EDI businesses in order to achieve greater
      economies of scale and to remain a cost effective provider of transaction
      processing services. EDSS will target for acquisition or alliances
      companies with profitable transaction volumes and revenue producing
      technologies.
 
    - INCREASE THE SERVICES PROVIDED ELECTRONICALLY TO HEALTH CARE INDUSTRY
      PARTICIPANTS. The Company believes that much of the information that flows
      from and among each of the various participants in the health care market
      can be transmitted electronically with greater efficiency and cost
      effectiveness. EDSS plans to expand its services to include more
      adjudication capabilities and eventually eligibility and benefits
      verification, referrals, authorizations, enrollment capabilities,
      electronic remittance advice and electronic funds transfer, in addition to
      existing eligibility and referral capabilities Expanded real-time capacity
      will be necessary in order to report on the status of claims, gather and
      link clinical data with claims processing, and provide comparative data
      for providers who wish to subscribe to these optional services.
 
    -- COMPANY SERVICES
 
    EDSS' EDI services for third-party Payors, providers and billing services
include: electronic submission of claims, encounters, patient eligibility,
referrals and authorizations, claims status inquiry and remittance advice, and
customized reporting capabilities.
 
    TRANSACTION PROCESSING.  EDSS is a substantial processor of commercial
third-party Payor claims and plans to enhance its electronic network by
increasing connections with health care providers and Payors across the United
States. Network transactions are predominantly used to process reimbursement
claims in traditional fee-for-service commercial or government Payor systems and
to process encounter data in capitated environments. To submit claims, providers
collect data throughout the day using software provided by EDSS and then
electronically forward these claims in bulk to EDSS. EDSS electronically
collects and verifies receipt of the claims, performs Payor specific edits and
reformatting required to conform to a particular Payor's specifications,
aggregates daily transactions by Payor and transmits claims to Payors based upon
each Payor's chosen communications protocols. EDSS processed an aggregate of
approximately 8 million commercial third-party Payor claims in the fiscal year
ended September 30, 1997. EDSS' transaction network is connected with 540 of the
approximately 1,500 commercial third-party Payors, including all of the top 20
commercial Payors (based upon the number of members covered by such third-party
Payors).
 
    EDI INTERFACES.  EDSS has developed a range of hardware and software
interfaces to facilitate the adoption of EDI by providers and Payors.
 
    HECET SYSTEMS.-REGISTERED TRADEMARK-  HECET Systems-Registered Trademark-, a
proprietary PC-based software product, was developed by EDSS in 1993 and is
designed with open Application Program Interfaces ("APIs"). The APIs are
established at the operating system level and enable EDSS software to run on a
wide variety of operating systems including DOS, UNIX and Windows. HECET
Systems-Registered Trademark- functions as stand alone edit, formatting and
communications software for providers and Payors. The stand alone version of
HECET Systems-Registered Trademark- is offered directly to providers for a
nominal price.
 
    PAYOR GATEWAY.  EDSS has recently developed software to enable Payor
organizations to participate in EDI without requiring the Payor to develop
interface technology. EDSS' "Payor Gateway" software is designed to facilitate
the movement of transactions to and from the Payors' software. The Payor Gateway
manages telecommunications access, security and the retrieval of data and allows
the Payor to participate in EDI with EDSS assuming the responsibility for
interfacing the Payor Gateway software to the Payor's system.
 
    CUSTOMER SERVICE.  As an adjunct to its transaction processing services,
EDSS maintains customer service facilities with help desks for real-time
customer inquiries. Client support employs a modern call
 
                                       5
<PAGE>
tracking and response system which is directly connected to the processing
center. Customer support services, available via telephone, are frequently
included in the contract price for transaction processing services, but may also
be billed separately, depending upon the specific contract terms. EDSS also
offers other services, such as on-site product training and installation.
 
    -- SALES AND MARKETING
 
    EDSS develops and maintains Payor, provider and vendor relationships through
its sales and marketing personnel located in five geographic regions. EDSS'
primary sales and marketing strategy focuses on selling its services to
organizations that have relationships with or access to a large number of
providers. EDSS' services are also sold directly to providers.
 
    To market its claims processing services, EDSS develops relationships with
third-party Payors and large submitters of claims. In addition, EDSS works
closely with practice management system vendors to provide an integrated
solution to providers. Real-time managed care EDI services are offered to
providers either directly by EDSS' sales force or indirectly through commercial
managed care organizations.
 
    -- CUSTOMERS
 
    The Company's principal customers consist of health care providers, such as
physicians, hospitals, clinics and billing services, and third-party Payors,
such as indemnity insurers, managed care organizations and state and federal
governmental agencies. No customer accounted for 10% or more of the Company's
revenues during fiscal 1997 or 1996.
 
    EDSS typically provides real-time services to customers under contracts that
are not exclusive and generally do not guarantee a specific transaction volume
or revenue stream. The pricing of EDSS' services is set under contracts
typically having terms of one to three years, subject to a variety of early
cancellation arrangements.
 
    EDSS' transactions include contracts with both Payors and claim submitters,
including providers, practice management system vendors, clearinghouses, billing
services and others. Submitter contracts with EDSS often contain exclusivity
provisions whereby the submitter agrees to process the claim through EDSS if
EDSS has network access to the Payor.
 
    -- OPERATIONS
 
    EDSS delivers its real-time services through an integrated electronic
transaction processing system, which includes EDSS-designed software, host
computer hardware, network management, switching services and the ability to
interact with the customers' personal computers and a variety of
point-of-service devices, most of which were originally designed by EDSS.
 
    EDSS' real-time host computer system consists of advanced computer networks
designed and configured to operate 24 hours a day, seven days a week. These
networks are configured to expand to meet increased transaction volume. The
networks are designed and manufactured to accommodate a fault-tolerant, nonstop
environment by maintaining on-line standby computers. The data center is further
protected by uninterruptible power supply systems. The software and related data
files are backed up nightly and stored off-site.
 
    EDSS' communications network consists of dedicated circuits, T-l facilities
and dial modem ports, which facilitate electronic real-time communication among
Payors, providers and other users of time-sensitive health care information.
This communications network is designed to provide a low cost, multipath host
access from a computer modem or point of service device with minimal delays and
a high degree of accuracy and integrity. EDSS uses a number of different
nationwide public communications networks to provide access to substantially all
potential domestic customers.
 
                                       6
<PAGE>
    -- PROPRIETARY RIGHTS
 
    EDSS owns certain of the software and systems designs that it uses and has a
limited, perpetual, nonexclusive, royalty-free license to use other software and
systems designs, such as the point-of-service device designs. The Company also
licenses certain other software from third parties.
 
    EDSS' success is dependent in part upon electronic transaction processing
technology developed by EDSS. A combination of trade secret, copyright,
trademark and contract protection is used to establish and protect that
technology. There can be no assurance these legal protections and the
precautions taken by EDSS will be adequate to prevent misappropriation of
technology used by EDSS. In addition, the legal protections do not prevent
independent third-party development of competitive technology.
 
    -- COMPETITION
 
    EDSS faces potential competition in the healthcare EDI market not only from
other companies that are similarly specialized, but also from companies involved
in other, more highly developed sectors of the electronic transaction processing
market. Such companies could enter into, or focus more attention on, the
healthcare transaction processing market as it develops. In addition, EDSS faces
competition by selected providers bypassing EDSS' electronic network and going
directly to the Payor. Many of EDSS' existing and potential competitors have
greater financial, marketing and technological resources. EDSS' principal
competitors include Envoy/NEIC, QuadraMed, HBO&Co, EDI USA and National Data
Corp. There is no assurance that EDSS can continue to compete successfully with
its existing and potential competitors in the health care EDI market.
 
    Factors influencing competition in the health care market include (i)
compatibility with the provider's software and inclusion in practice management
products, (ii) relationships with third-party Payors and managed care
organizations and (iii) price and quality of service.
 
    -- GOVERNMENT REGULATION AND HEALTH CARE REFORM
 
    The United States Food and Drug Administration (the "FDA") is responsible
for assuring the safety and effectiveness of medical devices under the Federal
Food, Drug and Cosmetic Act. Computer products are subject to regulation when
they are used or are intended to be used in the diagnosis of disease or other
conditions, or in the cure, mitigation, treatment or prevention of disease, or
are intended to affect the structure or function of the body. The FDA could
determine in the future that any predictive aspects of EDSS' products make them
clinical decision tools subject to FDA regulation. Compliance with these
regulations could be burdensome, time consuming and expensive. EDSS also could
become subject to future legislation and regulations concerning the development
and marketing of health care software systems. These could increase the cost and
time necessary to market new products and could affect EDSS in other respects
not presently foreseeable. EDSS cannot predict the effect of possible future
legislation and regulation.
 
    The confidentiality of patient records and the circumstances under which
such records may be released for inclusion in EDSS' databases are subject to
substantial regulation by state governments. These state laws and regulations
govern both the disclosure and the use of confidential patient medical record
information. Although compliance with these laws and regulations is at present
principally the responsibility of the hospital, physician or other health care
provider, regulations governing patient confidentiality rights are evolving
rapidly. Additional legislation governing the dissemination of medical record
information has been proposed at both the state and federal level. This
legislation may require holders of such information to implement security
measures that may require substantial expenditures by EDSS. There can be no
assurance that changes to state or federal laws will not materially restrict the
ability of health care providers to submit information from patient records
using EDSS' products.
 
                                       7
<PAGE>
    The health care industry is highly regulated and subject to changing
political, economic and regulatory influences that may affect the procurement
practices and operation of health care organizations. EDSS' products are
designed to function within the structure of the health care financing and
reimbursement system currently being used in the United States. Changes in the
current health care financing and reimbursement systems could result in the need
for unplanned product enhancements, delays or cancellations of product orders or
shipments, or the revocation of endorsement of EDSS' products by hospital
associations or other customers. Any of such occurrences could have a material
adverse effect on EDSS' business, financial condition and results of operations.
During the past several years, the United States health care industry has been
subject to an increase in governmental regulation of, among other things,
reimbursement rates. Certain proposals to reform the U.S. health care system are
periodically considered by Congress and certain state legislatures. These
programs may contain proposals to increase governmental involvement in health
care and otherwise change the operating environment for EDSS' customers and
potential customers. Health care organizations may react to these proposals and
the uncertainty surrounding such proposals by curtailing or deferring
investments, including those for EDSS' products. On the other hand, changes in
the regulatory environment have increased and may continue to increase the needs
of health care organizations for cost-effective information management and
thereby enhance the marketability of EDSS' products and services. EDSS cannot
predict with any certainty what impact, if any, such proposals or health care
reforms might have on EDSS' business, results of operations and financial
condition. In addition, many health care providers are consolidating to create
integrated health care delivery systems with greater regional market power. As a
result, these emerging systems could have greater bargaining power, which may
lead to price erosion of EDSS' products. The failure of EDSS to maintain
adequate price levels would have a material adverse effect on EDSS' business,
financial condition and results of operations. Other legislative or
market-driven reforms could have unpredictable effects on EDSS' business,
financial condition and results of operations.
 
    -- FACILITIES
 
    EDSS' executive and corporate offices are located in Colorado Springs,
Colorado in approximately 6,500 square feet of office space under a lease that
expires April 30, 1998. EDSS also maintains offices at Ft. Lauderdale, FL,
Orlando, FL, Tampa, FL, and Dallas, TX. EDSS believes that its facilities are
adequate for its current operations.
 
    -- EMPLOYEES
 
    As of January 15, 1998 EDSS had approximately 44 employees, including
approximately 29 salaried and 15 hourly employees (including temporary
employees). None of these employees is represented by a union or other
collective bargaining group. EDSS believes its relationship with the employees
is good.
 
    -- LITIGATION
 
    EDSS is not currently party to any litigation.
 
WIRELESS CABLE BUSINESS
 
    -- GENERAL
 
    Wireless cable television is provided to subscribers by transmitting
microwave frequencies over the air on a direct "line-of-sight" from the
transmission facility to a small receiving antenna at each subscriber's
location. Local off-air VHF/UHF broadcasts can be provided to a subscriber by
retransmission of the broadcast over a wireless frequency or by installation of
an off-air antenna in conjunction with the wireless antenna located on the
subscriber's home or building.
 
    Wireless cable technology eliminates the need for large networks of cable
and amplifiers utilized by hard-wire cable television operators. To the
subscriber a wireless cable system generally operates in the
 
                                       8
<PAGE>
same fashion as a hard-wire cable system. Like the hard-wire cable systems,
wireless cable systems, in exchange for monthly fees, typically offer local
off-air broadcast channels, as well as programming such as HBO, ESPN, CNN, USA,
WGN, WTBS, A&E, Nickelodeon, Discovery, Disney, MTV and other programming
services. A wireless cable system utilizes microwave frequencies licensed by the
FCC to transmit multiple channels of video programming over the airwaves to
small receiving antennas mounted at the subscribers' locations. Additional
pay-per-view programming, such as recent movie releases and special sports
events, is generally available for a supplemental charge.
 
    The Company does not currently own any wireless cable systems or channels,
and, while the Company continues to seek and review opportunities in this area,
it has no specific agreements or understandings to acquire any such assets.
 
    -- SALE OF SOUTH FLORIDA TELEVISION
 
    In June 27, 1997, the Company completed the sale of its subsidiary, South
Florida Television Inc., which held its rights to provide wireless cable TV
service in Miami, to BellSouth Corporation (NYSE: BLS) for 1,048,321 shares of
BellSouth common stock, based on a $48 million purchase price.
 
    -- STRATEGIC ALLIANCES AND INVESTMENTS
 
    SPIKE TECHNOLOGIES.  On June 20, 1996, the Company entered into an agreement
with Spike Technologies, Inc. ("Spike") for testing of Spike's bidirectional
multipoint microwave antenna technology. The Company expects to invest up to
$500,000 in such testing but has not yet done so. The Company will have the
exclusive right to use Spike's technology in Florida, subject to certain
royalties to Spike. The Company will have the exclusive right to market Spike's
technology to wireless cable operators, including telephone companies, with a
royalty of 5% payable to the Company. In addition, the Company shall receive a
warrant to purchase 5% of Spike's common stock.
 
    DEVELOPING TECHNOLOGY.  The Company is reviewing on a preliminary basis
investments in or acquisitions of telecommunications technology companies
 
OTHER OPERATIONS
 
    LANDTEL COMMUNICATIONS, INC.  In December 1997 the Company acquired a 24%

Anagram was organized in Delaware on August 22, 1995 to engage in, among other
things, the business of acquiring European television programming for U.S.
distribution via wireless cable transmission. The Company has invested an
additional $322,173 in Anagram. The majority of Anagram's programming consists
of educational series relating to science and technology, natural history,
history and world cultures and "how to" programs. The Company believes that
Anagram will provide valuable programming for educational television, including
ITFS wireless cable channel owners.
 
    TLC PRODUCTIONS.  On August 22, 1995, the Company completed the acquisition
of all of the outstanding capital stock of TLC Productions, Inc. ("TLC"), from
its sole shareholder. TLC is a full-service teleport and uplink facility located
in North Miami, Florida, that provides satellite uplink services to clients who
then are able to rebroadcast signals to video programming distributors.

RESULTS OF OPERATIONS
 
1997 AS COMPARED TO 1996
 
Gain on Sale of SFTV:
 
    During 1997, the Company realized a pre-tax gain of $44,196,516 from the
sale in a tax-free reorganization of the Company's wireless cable subsidiary
("SFTV") in Miami, Florida in exchange for $48,000,000 of BellSouth common
stock. The Company recorded $16,900,000 of deferred income taxes on such gain.
In addition, the Company had a net unrealized gain of $959,275 as of October 31,
1997 on its positions in BellSouth common stock.
 
Service Revenue:
 
    Service revenue increased from $1,223,561 in 1996 to $3,308,080 in 1997 as a
result primarily of increased revenues of TLC in 1996 and the addition of
revenues from the acquisition of a controlling interest in EDSS in December
1996.
 
Interest and Dividend Income:
 
    Interest income decreased from $1,094,173 in 1996 to $870,810 in 1997 as a
result of a reduction in funds invested in interest bearing instruments.
Dividend income increased from $0 in 1996 to $538,791 in 1997, reflecting net
dividends on the BellSouth common stock.
 
Cost of Services:
 
    Cost of services increased from $799,045 in 1996 to $1,626,661 in 1997 as a
result of increased costs of operation of TLC and costs associated with the
operations of EDSS.
 
Wireless Market and Technology Development:
 
    Market development expenses decreased from $798,870 in 1996 to $455,422 in
1997 as a result of lower activity in the development of the Miami market and
the sale of the related assets in June 1997. Technology development expenses
increased from $35,370 in 1996 to $100,000 in 1997.
 
Professional Fees:
 
    Professional fees increased from $273,234 in 1996 to $473,430 in 1997 as a
result of increased activity relating to various transactions in 1997.
 
General and Administrative:
 
    General and administrative expense increased from $790,511 in 1996 to
$2,459,347 in 1997 as the Company incurred additional costs in connection with
selling its wireless cable assets in the Miami market and increased costs
relating to the operations of EDSS.
 
Depreciation and Amortization:
 
    Depreciation and amortization increased from $564,139 in 1996 to $832,413 in
1997 as a result of the effect during 1997 of the acquisition of EDSS and
increased amounts of equipment placed in service during 1996 at TLC.
 
Net Income (Loss):
 
    As a result of each of the foregoing events, net income amounted to
$25,959,164 in 1997 as compared to a loss of ($1,016,824) in 1996.
 
                                       13
<PAGE>
1996 AS COMPARED TO 1995:
 
Service Revenue:
 
    Service revenue increased from $945,616 in 1995 to $1,223,561 in 1996 as a
result primarily of increased revenues of TLC in 1996.
 
Interest Income:
 
    Interest income decreased from $1,154,673 in 1995 to $1,094,173 in 1996 as a
result of a reduction in funds invested in interest bearing instruments due to
investments in affiliates and subsidiaries and acquisitions of transmission
equipment.
 
Cost of Services:
 
    Cost of services increased from $512,449 in 1995 to $799,045 in 1996 as a
result of increased costs of operation of TLC.
 
Wireless Market and Technology Development:
 
    Market development expenses decreased from $835,560 in 1995 to $798,870 in
1996 as a result of lower activity in the development of the Miami market.
Technology development expenses decreased from $39,776 in 1995 to $35,370 in
1996 as a result of lower activity in technology development in 1996.
 
Professional Fees:
 
    Professional fees decreased from $294,547 in 1995 to $273,234 in 1996 as a
result of less acquisition activity in 1996.
 
General and Administrative:
 
    General and administrative expense increased from $641,737 in 1995 to
$790,511 in 1996 as the Company incurred additional costs while developing the
Miami market.
 
Depreciation and Amortization:
 
    Depreciation and amortization increased from $363,232 in 1995 to $564,139 in
1996 as a result of certain equipment being placed in service during 1996 which
resulted in the commencement of depreciation and amortization.
 
Net Loss:
 
    As a result of each of the foregoing events, net loss increased from
$640,081 in 1995 to $1,016,824 in 1996.
 
EDSS RESULTS OF OPERATIONS:
 
EDSS has incurred operating losses of $1,580,183 on a cumulative basis through
September 30, 1997, including $297,508 in 1997, $501,334 in 1996 and $771,545 in
1995. Such losses have been financed principally through a $400,000 loan from
EDSS' President and a $1,000,000 line of credit from the Company pursuant to a
loan agreement, which has been substantially utilized as of October 31, 1997.
Based upon existing contracts with physicians and providers and current expense
levels, management believes that EDSS would achieve positive cash flow from
operations for fiscal 1998 without the need to obtain additional financing.
EDSS, however, may seek to obtain additional financing, and the Company may
provide additional funds, to accelerate EDSS' strategic business plan.

LIQUIDITY AND CAPITAL RESOURCES
 
    The Company funds its operations with the net proceeds from its initial
public offering in 1994 of 2,000,000 shares of Common Stock aggregating, after
payment of offering costs, approximately $22,000,000 and the recent sale of its
South Florida wireless cable subsidiary for $48 million in BellSouth common
stock. The proceeds have been used for, and are currently reserved to fund
acquisitions of, additional EDI (electronic data interchange) investments,
wireless telecommunications assets, media businesses, development of its other
businesses and development and acquisition of new technologies and businesses in
other areas. Such amount, with interest thereon, is expected to be sufficient to
implement this business plan through October 1999, or for a shorter period if
the Company determines to invest a substantial portion of its assets in major
acquisitions or equity investments. Following completion of the sale of its
South Florida wireless cable assets, the Company has allocated its capital to
development of its other businesses and to acquisitions.
 
    As of October 31, 1997, the Company had approximately $54 million in cash
and net marketable BellSouth common stock as well as its interest in EDSS, its
full-service teleport and satellite uplink facility in Miami, its investment in
an educational video programming distributor, its investment in Landtel, and
investments in other early stage companies.
 
    Prior to completion of the merger of its South Florida subsidiary with a
BellSouth subsidiary, the Company sold 300,000 shares of BellSouth common stock
short, and, prior to the end of fiscal 1997, sold 50,000 additional shares of
BellSouth common stock short, and received an aggregate of approximately
$15,920,000 in cash proceeds from such sales. Subsequent to year-end, the
Company settled 150,000 shares of its short position outstanding as of October
31, 1997. While the Company continues to review its position in BellSouth common
stock and from time to time since year-end has sold and purchased shares and
options on the position, it has not yet determined whether it will sell or hedge
its remaining BellSouth securities in the near future or how it will invest the
proceeds of any such sale.
 
    In October 1997, the Company paid an aggregate of $4,267,900 as a $1.30 per
share dividend to common stockholders of record on September 12, 1997.
 
    On September 10, 1997, the Company purchased for $750,000 from a stockholder
an additional 5% of the common stock of Electronic Data Submission Systems, Inc.
("EDSS"), which when combined with its existing share ownership represents 55%
of the outstanding common stock and control of EDSS. In addition, pursuant to a
loan agreement between EDSS and the Company, dated June 19, 1995, the Company
has outstanding loans to EDSS of $988,000, which have been eliminated from the
balance sheet in consolidation. The Company may invest additional amounts in
EDSS to finance its sales growth.
 
    The Company may, when and if the opportunity arises, acquire or invest in
other businesses in the wireless telecommunications industry, media businesses
or in unrelated areas. If such an opportunity arises, the Company may use a
portion of its funds for that purpose. For instance, the Company has invested
$240,000 in Landtel, and may invest up to an additional $9,600,000 in Landtel to
fund a possible acquisition of a British telecommunications company. Other than
Landtel, the Company has no specific arrangements with respect to any such
acquisitions or investments at the present time and is not currently involved in
any negotiations with respect to any such acquisition. There can be no assurance
that any such acquisitions or investments will be made.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
National Wireless Holdings Inc.:
 
    We have audited the accompanying consolidated balance sheets of NATIONAL
WIRELESS HOLDINGS INC. as of October 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the years in the three year period ended October 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of National
Wireless Holdings Inc. as of October 31, 1997 and 1996, and the consolidated
results of their operations and their cash flows for each of the years in the
three year period ended October 31, 1997, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. COMPANY OPERATIONS AND BASIS OF PRESENTATION:
 
    National Wireless Holdings Inc. (the "Company"), a Delaware corporation
organized on August 31, 1993, is a holding and strategic resource company
generally for telecommunications and other businesses. The Company currently
operates an electronic data interchange company, providing links between
healthcare providers and third party payors. In addition, the Company operates a
satellite programming uplink facility, an educational programming distribution
company and other early stage businesses. The Company also seeks to support,
finance and acquire new businesses and technologies in the telecommunications
and other industries. The Company recently acquired an interest in a company
organized to purchase a British telecommunications company, and may acquire or
invest in other businesses. In June 1997, the Company sold its wireless cable
assets in Miami Florida in exchange for common stock of BellSouth Corporation
(see Note 3).
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
CASH EQUIVALENTS:
 
    The Company considers all highly liquid investments with maturities, when
purchased, of three months or less to be cash equivalents. Cash equivalents
consist primarily of investments in various money market funds.
 
MARKETABLE SECURITIES:
 
    The Company's marketable securities consist of an investment in BellSouth
Corporation common stock. The Company's marketable equity securities have been
classified as available for sale. Available for sale securities are carried at
fair value, with unrealized gains and losses, net of tax effects, reported as a
separate component of stockholders' equity, until realized.
 
WIRELESS FREQUENCY LICENSE AND ACQUISITION COSTS:
 
    Wireless frequency license and acquisition costs are capitalized and
amortized on the straight-line method over the life of the related agreements,
which range from 5 to 10 years. License and acquisition costs are expensed when
management determines that the related market will not be developed and the
costs cannot be recovered through resale.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS:
 
    Equipment is recorded at cost and depreciation expense is provided under the
straight-line method over the estimated useful lives of the related assets,
which range from 5 to 10 years; leasehold improvements are amortized over the
shorter of the life of the improvements or the related lease term.
 
INTANGIBLE ASSETS:
 
    Intangible assets consist primarily of goodwill. Goodwill represents the
excess of the purchase price over the net assets of acquired companies and is
being amortized on the straight-line method over 10 to 15 years.

    Based upon events or changes in circumstances, the Company assesses any
impairment in value of its long-lived assets, including intangible assets, by
making a comparison of the current and projected operating cash flows of each of
its assets over its remaining useful life, on an undiscounted basis, to the
carrying amount of the related assets. Such carrying amounts would be adjusted,
if necessary, to reflect any impairment in value.
 
INCOME TAXES:
 
    The Company accounts for income taxes under the liability method of
accounting. Under the liability method, deferred taxes are determined based on
differences between the financial statement and tax bases of assets and
liabilities at enacted tax rates in effect in the year in which the differences
are expected to reverse. Valuation allowances are established, when necessary,
to reduce deferred tax assets to the amounts expected to be realized.
 
NET INCOME (LOSS) PER SHARE DATA:
 
    Net income (loss) per share is computed based on net income (loss) for the
period divided by the weighted average number of common shares and common share
equivalents outstanding during the period.
 
ESTIMATES:
 
    The presentation of financial statements in conformity with generally
accepted accounting principles requires the Company's management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenue and expenses
during the reporting period. Actual results could differ from those estimates.
 
RECENTLY ISSUED PRONOUNCEMENTS:
 
    The Company has adopted the disclosure only provisions of SFAS No. 123
"Accounting for Stock Based Compensation." The Company has considered the impact
of SFAS Nos. 128, 129, 130 and 131 will have on the Company's financial position
and results of operations when adopted and does not believe it to be material.
 
3. SALE OF SFTV:
 
    On February 26, 1997, the Company and its wholly-owned subsidiary, South
Florida Television, Inc. ("SFTV") entered into an Agreement and Plan of
Reorganization, as amended, (the "Merger Agreement") which became effective on
June 27, 1997 with BellSouth Corporation ("BellSouth") and its wholly-owned
subsidiary, Bell South South Florida Merger Subsidiary, Inc. ("BellSouth Sub"),
pursuant to which BellSouth Sub merged into SFTV. SFTV became a wholly-owned
subsidiary of BellSouth and the Company received an aggregate of $48,000,000 in
BellSouth common stock (the "Merger") which resulted in a pre-tax gain of
approximately $44,200,000 The Merger has been treated as a tax-free
reorganization.

    In August 1996, the Company completed a partial exercise of its option to
acquire a 50% interest in Electronic Data Submission Systems, Inc. ("EDSS") by
purchasing 11% of EDSS voting common stock for $343,800 in cash. The investment
is carried at cost in the accompanying consolidated balance sheet as of October
31, 1996.
 
    On December 13, 1996, the Company exercised a warrant and an option to
purchase additional shares of the common stock of EDSS, which when combined with
its existing share ownership represents 50% of the outstanding common stock and,
pursuant to the EDSS Shareholders Agreement, dated as of July 25, 1996, control

which an aggregate of $887,500 was paid to EDSS and $1,000,000 was paid to the
principal stockholder of EDSS.
 
    The acquisition has been accounted for under the purchase method of
accounting and the results of operations from the date of purchase have been
reflected in the consolidated statement of operations. On September 10, 1997,
the Company purchased an additional 5% of the common stock of EDSS from the
president of EDSS for $750,000. The purchase price has been allocated
principally to intangible assets (goodwill) and is being amortized over 15

processing while enhancing the payment process. The Company has entered has
entered into various service agreements with health care providers including
FHS, Inc., FHP Health Care, Metra Health Insurance Company, Mutual of Omaha and
Prudential Insurance Company.
 
    EDSS has incurred operating losses of $1,580,183 on a cumulative basis
through September 30, 1997. Such losses have been financed principally through a
$400,000 loan from the Company's president and a $1,000,000 line of credit from
the Company. Based upon existing contracts with physicians and providers and
current expense levels, management of EDSS believes that it will achieve
positive cash flow from operations for fiscal 1998 without the need to obtain
additional financing. The Company, however, may seek to obtain additional
financing to accelerate its strategic business plan.
 
5. LEASE AND PURCHASE COMMITMENTS:
 
    The Company leases administrative facilities and office equipment under
operating leases that expire between 1999 and 2002. Certain of the leases
contain escalation clauses providing for increased rentals based on operating
expenses or the consumer price index. Rent expense, net of rental income under
operating leases was approximately $243,000, $200,000 and $188,000 for the years
ended October 31, 1997, 1996 and 1995, respectively.

8. INCOME TAXES:
 
    As of October 31, 1997, the deferred income tax liability relates to the
gain on sale of SFTV. As of October 31, 1996, deferred tax assets, principally
$1,800,000 of net operating loss carryforwards, were offset by a 100% valuation
allowance. During 1997 these NOL's were either utilized to reduce taxable income
or were transferred to BellSouth as part of the sale of SFTV.
 
    The difference between the actual provision for income taxes and the
provision for income taxes computed by applying the statutory federal rate to
income before provision for income taxes is attributable to the following:

    No options were forfeited or expired during any period presented. The
remaining weighted average contractual life of options outstanding at October
31, 1997 was 4.15 years.
 
    The Company has elected to adopt the disclosure-only provisions of Statement
of Financial Accounting Standards No. 123 "Accounting for Stock-Based
Compensation". Accordingly, no compensation cost has been recognized with regard
to options granted under the Plan in the accompanying financial statements. If
stock-based compensation costs had been recognized based on the estimated fair
values at the dates of grant for options awarded during 1997, net income and net
income per common share for 1997 would have been reduced by approximately
$125,000, or $.04 per share.
 
    These pro forma adjustments to net income and net income per common share
assume fair values of each option grant estimated using the Black-Scholes option
pricing formula. The more significant assumptions underlying the determination
of such fair value for options granted during 1997 include: (i) weighted average
risk-free interest rates of 5.92%; (ii) weighted average expected option life of
5 years; (iii) an expected volatility of 41%, and (iv) an expected dividend
yield of 0%. The per share weighted average fair value at the dates of grant for
options awarded during 1997 was $4.67.
 
11. RELATED-PARTY TRANSACTIONS:
 
    On July 9, 1997 the Company loaned $1,100,000 to an officer of the Company
under a note receivable which bears interest at 8% and is due on July 9, 1998.
The officer pledged 100,000 shares of the Company's common stock as collateral.
The balance, including accrued interest, is $1,178,093 as of October 31, 1997.
 
    The note payable to related party of $400,000 as of October 31, 1997
represents a loan by EDSS to the president of EDSS. The note bears interest at
the bank's prime rate plus 2% (10.5% at October 31, 1997) and is due on demand
after the full payment of an intercompany loan of $998,000 due from EDSS to the
Company.
 
    In fiscal 1997, 1996 and 1995, the Company purchased new service vehicles
from an automobile dealership which is owned by the Chairman of the Company for
approximately $29,000, $33,000 and $76,000, respectively.
 
    The Company leases office space in Rantoul, Illinois from a company which is
owned jointly by the Chairman and an officer of the Company, for $1,750 per
month. The lease agreement is on a month-to-month basis based on the needs of
the Company. The Company also subleases office space in New York to a company
owned by a director of the Company for $800 per month. The sublease, which
commenced December 1, 1994, is on a month-to-month basis based on the needs of
the Company.
 
12. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
    The following methods and assumptions were used to estimate the fair value
of each category of financial instruments:
 
CASH AND CASH EQUIVALENTS:
 
    Cash equivalents comprise money market funds whose carrying amounts
approximate fair value due to the short-term maturity of the instruments.

12. FAIR VALUE OF FINANCIAL INSTRUMENTS: (CONTINUED)
LONG-TERM DEBT AND NOTE PAYABLE:
 
    Long-term debt relates principally to service vehicle loans payable and a
note payable to a related party. Interest rates on the loans approximate the
rates available at October 31, 1997 and the Company believes that their carrying
value of debt at October 31, 1997 approximates fair value.
 
MARKETABLE SECURITIES:
 
    Marketable securities are reflected at fair value in the accompanying
consolidated balance sheet at October 31, 1997.
 
13. QUARTERLY FINANCIAL INFORMATION (UNAUDITED):
 
    Quarterly information for 1997, 1996 and 1995 is set forth in the table

</TABLE>
 
    The sum of the quarterly net income (loss) per common share amounts for 1997
are not equal to the full year amount primarily because the computations of the
weighted average number of common shares outstanding for each quarter and the
full year are made independently.
 
14. SUBSEQUENT EVENTS (UNAUDITED):
 
    Subsequent to year end, the Company settled 150,000 shares of its short
position outstanding as of October 31, 1997 which resulted in a realized loss of
approximately $960,000, net of a deferred tax benefit of $640,000.
 
    In December 1997 the Company acquired a 24% interest in Landtel
Communications, Inc. ("Landtel"), a company organized to purchase a U.K.
telecommunications company, for $240,000 plus a commitment to provide up to
$9,600,000 in the event Landtel completes the proposed acquisition. There can be
no assurance that Landtel will complete the proposed acquisition or otherwise
carry on any business.
