                                  THE COMPANY
 
     The Company is one of the fastest growing providers of wireless messaging
services in the United States. The Company has grown to become the fifth largest
paging carrier in the United States, based on 1,374,146 subscribers at March 31,
1996. The Company's number of subscribers has increased at annual growth rates
of 180%, 136% and 60% in 1993, 1994 and 1995, respectively, as compared to an
average annual growth rate of approximately 31% for 1993 through 1995 for the
paging industry. The Company has made no acquisitions, and all subscriber growth
has been internally generated. The Company has invested heavily in order to
achieve rapid growth in its subscriber base and, as a result, the Company has
sustained net losses of $31.1 million, $45.8 million, $53.1 million and $11.6
million for 1993, 1994, 1995 and the three months ended March 31, 1996,
respectively.
 
     The Company offers local, multi-city, regional and nationwide paging and
other one-way wireless services in all 50 states, covering 90% of the population
of the United States. The Company also provides services in Puerto Rico, the
U.S. Virgin Islands and the Bahamas, and has recently initiated nationwide
services in Canada. The Company employs a digital, state of the art transmission
network that is 100% FLEX(R) enabled, allowing the use of high speed messaging
technology thereby providing increased transmission capacity.
 
OPERATING STRATEGY
 
     The Company attributes the significant growth of its paging business to the
successful implementation of its six operating principles: (i) diversified
distribution channels, (ii) nationwide common frequency, (iii) efficient network
architecture, (iv) spectrum-rich frequency position, (v) centralized
administration, and (vi) customer service capabilities.
 
          DIVERSIFIED DISTRIBUTION CHANNELS. The Company utilizes a number of
     distribution channels to market its products and services, including retail
     marketing, private brand strategic alliances and national sales offices.
 
             Retail Marketing. The Company believes that it is a leading
        supplier of paging units to consumers through retail distribution
        channels. The Company has been selected as the pager supplier for a
        number of leading retail chains, including Office Depot Inc., Comp USA,
        Inc., Montgomery Ward Company, Inc., Target Stores, Inc. and Best Buy,
        Inc.
 
             Private Brand Strategic Alliances. The Company was one of the first
        paging companies to broaden its distribution reach by establishing
        strategic relationships with large communications providers. The Company
        has established strategic relationships with GTE Corporation,
        Southwestern Bell Mobile Systems, AT&T Wireless Services, Ameritech
        Mobile Services, Inc. and long distance reseller EXCEL
        Telecommunications, Inc.
 
             National Sales Offices. The Company's national sales offices sell
        equipment and services through three distribution channels: direct
        sales, third-party resellers and local retailers. The
 
                                        4
<PAGE>   5
 
          Company has a direct sales force presence in over 75 Metropolitan
          Statistical Areas ("MSAs") through 65 offices.
 
          Management believes that a diversified approach to distribution is
     important to sustain growth as paging services more deeply penetrate the
     United States population, especially the consumer market. This
     diversification is a key element of the Company's strategy of expanding its
     subscriber base as rapidly as possible to increase cash flow through
     greater utilization of its nationwide wireless communications network. A
     diversified distribution strategy also provides a cost effective method for
     managing disconnection rates. The Company's average monthly disconnection
     rates for the twelve months ended December 31, 1994, December 31, 1995 and
     March 31, 1996 were 3.4%, 2.5% and 2.4% per month, respectively.
 
          NATIONWIDE COMMON FREQUENCY. The Company has constructed its
     nationwide messaging network on a common frequency. Use of a common
     frequency provides the Company with a number of important strategic
     advantages not available to many of its competitors, which operate on
     multiple frequencies across markets. The use of a common frequency enables
     the Company's customers to travel throughout the United States, Canada and
     the Bahamas while continuing to use the same messaging device. As a result,
     the Company is able to provide multi-city coverage customized to
     accommodate the customer's needs ("coverage on demand"). The common
     frequency also provides a competitive advantage to the Company when
     marketing its services to regional and national retailers and private brand
     strategic alliance partners. These distributors are able to buy the paging
     unit without being limited by where they can distribute the product or by
     the service they sell with the unit. This allows retailers and strategic
     partners to offer customers all service options while minimizing the number
     of stock keeping units ("SKUs") that the distributor must carry, thus
     reducing inventory carrying costs.
 
          EFFICIENT NETWORK ARCHITECTURE. The Company is an industry leader in
     the implementation of advanced telecommunications technologies, including
     pioneering the use of direct broadcast satellite ("DBS") technology for
     paging. The Company's nationwide wireless transmission network is 100%
     controlled by DBS technology, which gives the Company a flexible, highly
     reliable and efficient network architecture. The use of DBS technology
     eliminates the need for expensive terrestrial radio frequency ("Rf")
     control links and repeater equipment while enabling the Company to provide
     a wide range of coverage options. The Company's network covers the top 300
     MSAs across the United States, or approximately 90% of the total population
     in the United States, and is designed to serve a significantly larger
     subscriber base than the one currently served by the Company. The Company's
     wireless transmission network is 100% FLEX enabled, allowing the use of the
     high speed FLEX protocol to transmit messages and maximize system capacity.
 
          SPECTRUM-RICH FREQUENCY POSITION. The Company ranks among the top four
     paging carriers in the United States in licensed nationwide frequencies.
     The Company's exclusive frequency licenses include two nationwide paging
     frequencies and 150 kHz of nationwide Narrowband Personal Communications
     Service ("NPCS") frequency (the "NPCS Licenses"). The Company believes that
     this frequency has important strategic value because it may enable the
     Company to grow significantly its one-way subscriber base and to provide
     two-way messaging and other value-added services to its subscribers. As a
     result, the Company believes its spectrum-rich frequency position enables
     it to attract private brand strategic alliance partners.
 
          CENTRALIZED ADMINISTRATION. The Company has centralized customer
     service, information systems, inventory control and distribution, credit
     and collections, accounting and marketing functions. This centralized
     administration has enabled the Company to become one of the lowest cost
     providers of paging and other one-way wireless communications services in
     the United States. In addition, the administrative infrastructure is
     designed to support a significantly larger customer base than that
     currently served by the Company, which will allow it to realize additional
     operating efficiency as the Company continues to grow.
 
          CUSTOMER SERVICE CAPABILITIES. Management has focused on developing
     industry-leading customer service capabilities. The Company employs over
     575 highly trained customer service personnel operating in state of the art
     call center facilities. Management believes that these services are an
     important factor in supporting and retaining its strategic partners,
     retailers and subscribers.

FINANCIAL STRATEGY
 
     The Company's principal financial objectives are to (i) maximize
profitability with respect to its existing subscriber base, as measured by
operating profit before selling expenses per subscriber and (ii) grow the
subscriber base on a cost efficient basis, as measured by selling expenses
(including loss on equipment sales) per net subscriber addition. See footnotes
(3) and (4) to "-- Summary Financial Information." The Company achieves
operating efficiency through its efficient transmission network, its nationwide
common frequency and its centralized administration. The Company's operating
profit before selling expenses per subscriber per month for the Company's
one-way operations was $1.01, $1.45, $1.66 and $2.11 during each quarter of
1995, and was $2.23 during the quarter ended March 31, 1996, although on an
overall basis the Company has sustained increasing net losses for each year of
its operations. See "Risk Factors -- History of Operating Losses." The Company's
selling expenses per net subscriber addition were $91, $81, and $91 in the years
ended 1993, 1994 and 1995, respectively and were $86 for the quarter ended March
31, 1996.
 
     The Company's operating model is unique in the industry in that it follows
a strategy of selling rather than leasing messaging equipment to subscribers. As
of March 31, 1996, approximately 99% of the Company's units were Customer Owned
and Maintained ("COAM"). This COAM strategy results in the Company having much
less capital invested in messaging equipment than other paging carriers, which
lease messaging equipment to a majority of their subscribers. The Company
believes that its COAM strategy, coupled with its network design, enables it to
incur significantly lower capital expenditures, depreciation and amortization,
and interest expense associated with serving subscribers than other companies.
Management measures capital efficiency by the amount of capital employed per
subscriber and believes capital efficiency is an important indicator of its
financial performance. The Company's capital employed per subscriber was $42 and
$40 at December 31, 1994 and 1995, respectively and was $41 at March 31, 1996.
 
     The Company's strategy is to expand its subscriber base as rapidly as
possible and, through a combination of scale, operating efficiency and capital
efficiency, to provide a significant return on capital employed.
 
TWO-WAY MESSAGING STRATEGY
 
     One of the Company's principal strategies is to become a leading provider
of two-way messaging services in the United States. Management believes that the
introduction of two-way messaging services may present significant future growth
opportunities to the Company by enabling it to provide a new generation of
advanced messaging services, including data messaging, stored voice messaging
and other services, to new and existing subscribers.
 
     The Company's two-way messaging strategy is founded on four principal
competitive advantages: (i) nationwide spectrum, (ii) incremental introduction
of technology, (iii) established diversified distribution channels, and (iv)
operating efficiency.
 
     NATIONWIDE SPECTRUM. With the acquisition of the NPCS Licenses, the Company
became one of four companies with 150 kHz or more of nationwide NPCS frequency.
As a result, the Company is positioned to create a high capacity nationwide
network capable of delivering local, multi-city, regional, or nationwide data
and stored voice messaging services to a large number of subscribers.
 
     INCREMENTAL INTRODUCTION OF TECHNOLOGY. The Company intends to introduce
two-way messaging technology by initially building upon its one-way transmission
network, enabling the Company to minimize the level of capital expenditures and
investments. The Company plans to introduce two-way stored voice service paced
to the availability of infrastructure equipment, subscriber devices and to meet
the market demand for such services.
 
     ESTABLISHED DIVERSIFIED DISTRIBUTION CHANNELS. The Company plans to
leverage its established diversified distribution channels to achieve efficient
marketing of its two-way services.
 
     OPERATING EFFICIENCY. The Company expects to utilize its existing one-way
network and centralized administration to minimize incremental costs of product
and service expansion. Management believes that the Company's centralized
customer service, information systems, inventory control and distribution,
credit and
 
                                        6
<PAGE>   7
 
collections, accounting and marketing organizations will be capable of
supporting the Company's two-way strategy.
 
     As a result of these operating advantages, the Company plans to provide a
complete array of two-way services at affordable prices, including data and
stored voice services, that the Company believes should appeal to a large number
of potential subscribers.
 
     The Company expects to begin testing two-way data and stored voice services
in the second quarter of 1996. Upon completion of testing, two-way data services
are expected to be marketed on a city-by-city basis beginning in late 1996.
Two-way data services may include guaranteed alphanumeric message delivery with
acknowledgment and message with response capabilities. In 1997, the Company
plans to introduce its VoiceMart(TM) service, which should provide subscribers
with the ability to receive stored voice messages directly to their messaging
devices. Introduction of the VoiceMart service will be paced to the availability
of infrastructure equipment, subscriber devices and market demand.
 
INTERNATIONAL EXPANSION
 
     The Company plans to provide messaging services in selected countries on a
seamless international network. Management believes that its technology,
operational structure and distribution strategies can be replicated in foreign
countries to establish nationwide wireless networks. In each country in which
the Company plans to offer paging and messaging services, the Company will seek
to obtain a nationwide frequency common to at least one of the nationwide
frequencies it holds in the United States in order to allow a single messaging
device to be used in multiple countries. The Company expects to pursue
international opportunities through minority interests in joint venture
arrangements whereby the Company would contribute its expertise in designing and
managing messaging services with minimal incremental capital investments.
 
     The Company's international strategy is initially to pursue opportunities
in North America, Latin America, and South America. One of the Company's
affiliates, PageMart Canada Limited ("PageMart Canada"), has obtained a
nationwide license in Canada based on a frequency common to one of its
frequencies in the United States. PageMart Canada began providing service in the
largest metropolitan areas in Canada to U.S. subscribers in March 1996 and to
Canadian subscribers in April 1996. Through PageMart International, Inc., the
Company owns 20% of the voting common stock of PageMart Canada. Additionally,
PageMart International Inc. owns 33% of the voting common stock of PageMart
Canada Holding ("Canada Holding") which owns the remaining 80% of the voting
common stock of PageMart Canada. The Company also provides paging coverage in
the Bahamas.
 
     As a result of its business strategy, the Company has structured its
business into three operating divisions: PageMart One-Way, PageMart Two-Way and
PageMart International.
 
     The Morgan Stanley Shareholders (as defined herein) currently own
approximately 60.4% of the outstanding Common Stock of the Company and
approximately 48.9% of the outstanding voting Common Stock. After giving effect
to the Offering, the Morgan Stanley Shareholders will own approximately 51.3% of
the outstanding Common Stock and 38.9% of the outstanding voting Common Stock
(approximately 50.1% and 37.7%, respectively of the outstanding Common Stock and
outstanding voting Common Stock if the Underwriters' over-allotment option is
exercised in full). The Morgan Stanley Shareholders have informed the Company
that they intend, upon the consummation of the Offering, to convert such number
of their shares of non-voting Common Stock so that, following such conversion,
the Morgan Stanley Shareholders will own, in the aggregate, 49% of the
outstanding voting Common Stock of the Company. See "Principal Stockholders."

                         SUMMARY FINANCIAL INFORMATION
 
     The following table sets forth summary historical financial information and
operating data of the Company for each of the five fiscal years ended December
31, 1995 and for the three months ended March 31, 1995 and 1996. The financial
information and operating data for each of the five fiscal years ended December
31, 1995 were derived from, and should be read in conjunction with,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," the Consolidated Financial Statements of the Company and the notes
thereto included elsewhere in this Prospectus. The financial information and
operating data for the three months ended March 31, 1995 and 1996 were derived
from the unaudited consolidated financial statements of the Company and, in the
opinion of management, include all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of such data. Interim
results are not necessarily indicative of results to be expected for the full
fiscal year.

- ---------------
 
(1) Based on the weighted average number of shares and share equivalents
    outstanding during the period, plus the issuance of 1,000,000 shares of
    Class A Common Stock offered hereby, representing the number of shares the
    proceeds of which are to be used to repay the Company's vendor indebtedness.
    Also assumes such repayment occurred at the beginning of the applicable
    period.
 
(2) Average monthly revenue per unit ("ARPU") is calculated by dividing (i)
    recurring revenues, consisting of fees for airtime, voicemail, customized
    coverage options, excess usage fees and other recurring revenues and fees
    associated with the subscriber base for the quarter by (ii) the average
    number of units in service for the quarter. For the fiscal year periods,
    ARPU is stated as the monthly average for the final quarter of the year.
 
(3) Operating profit (loss) before selling expenses (selling expenses include
    loss on sale of equipment) per subscriber for the Company's one-way
    operations is calculated by dividing (i) recurring revenues less technical
    expenses, general and administrative expenses and depreciation and
    amortization for the quarter by (ii) the average number of units in service
    for the quarter. Stated as the monthly average for the final quarter of the
    year for the fiscal year periods.
 
(4) Selling expenses per net subscriber addition for the Company's one-way
    domestic operations is calculated by dividing (i) selling expenses,
    including loss on sale of equipment, for the period by (ii) the net
    subscriber additions for the period.
 
(5) EBITDA represents earnings (loss) before interest, taxes, depreciation and
    amortization. EBITDA is a financial measure commonly used in the paging
    industry. EBITDA is not derived pursuant to generally accepted accounting
    principles ("GAAP") and therefore should not be construed as an alternative
    to operating income, as an alternative to cash flows from operating
    activities (as determined in accordance with GAAP) or as a measure of
    liquidity. The calculation of EBITDA does not include the commitments of the
    Company for capital expenditures and payment of debt and should not be
    deemed to represent funds available to the Company. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operations"
    for a discussion of the financial operations and liquidity of the Company as
    determined in accordance with GAAP.
 
(6) Reflects the acquisition of the NPCS Licenses in the Federal Communications
    Commission ("FCC") NPCS auctions. See "Business -- Government Regulation."

                                  RISK FACTORS
 
     Prior to making an investment decision, prospective investors should
carefully consider, along with the other matters referred to in this Prospectus,
the specific factors set forth below.
 
HISTORY OF OPERATING LOSSES
 
     The Company has sustained losses from operating activities in each year of
operations since its organization in 1989, including an operating loss of $3.2
million for the three months ended March 31, 1996 and an aggregate of $81.7
million of operating losses for the three-year period ended December 31, 1995.
The Company expects to continue to incur operating losses for the next several
years. In addition, management anticipates that the Company's average monthly
revenue per unit ("ARPU") will decline in the foreseeable future due to
increased competition and a higher mix of subscribers added through private
brand strategic alliance programs and third-party resellers, both of which yield
lower ARPU. Although the Company's one-way operations generated $1.4 million of
positive EBITDA for the first quarter of 1996, the Company has had negative
EBITDA in each year of its operations, and negative EBITDA of $10.1 million for
the year ended December 31, 1995. EBITDA is not derived pursuant to GAAP and
therefore should not be construed as an alternative to operating income, as an
alternative to cash flows from operating activities (as determined in accordance
with GAAP) or as a measure of liquidity. The calculation of EBITDA does not
include the commitments of the Company for capital expenditures and payment of
debt and should not be deemed to represent funds available to the Company. The
Company's operating losses and negative EBITDA have resulted principally from
expenditures associated with the establishment of the Company's one-way
operations infrastructure and the growth of its subscriber base. Although the
Company expects that its one-way operations will continue to generate positive
EBITDA, as the Company begins development and implementation of two-way
messaging services, the Company will incur substantial additional operating
losses and negative EBITDA during the start-up phase for two-way services. Any
positive cash flow from the Company's one-way operations will be used primarily
to fund the Company's two-way operations for the next several years. There can
be no assurance that the Company's consolidated operations will become
profitable or have positive EBITDA or that its one-way operations will continue
to generate positive EBITDA. If the Company cannot achieve operating
profitability or positive EBITDA, it may not be able to make required debt
service payments, and the Common Stock may have little or no value. See
"Selected Historical Financial and Operating Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
HIGH LEVERAGE; STOCKHOLDERS' DEFICIT; RESTRICTIVE COVENANTS
 
     The Company is highly leveraged, primarily as a result of debt financing
incurred to fund the construction of the Company's nationwide operations
infrastructure, the growth of its subscriber base and to finance the acquisition
of the NPCS Licenses. At March 31, 1996, the Company's long-term debt was $225.2
million and its stockholders' deficit was $23.7 million. In addition, the
accretion of original issue discount on the Company's outstanding indebtedness
will cause an increase in indebtedness of $126.6 million by 2001. The Company's
deficiency of earnings before fixed charges to cover fixed charges for the three
months ended March 31, 1996 was $11.6 million and for each of the three years
ended December 31, 1993, 1994 and 1995, was $31.1 million, $45.8 million and
$53.1 million, respectively. See "Capitalization" and "Selected Historical
Financial and Operating Data."
 
     The indenture pursuant to which the Company's 15% Senior Discount Notes due
2005 (the "15% Notes") were issued (the "15% Indenture") and the indenture
pursuant to which the 12 1/4% Senior Discount Notes due 2003 (the "12 1/4%
Notes") of the Company's operating subsidiary, PageMart, Inc. ("PageMart") were
issued (the "12 1/4% Indenture") contain certain restrictive covenants. Such
restrictions affect, and in many respects significantly limit or prohibit, among
other things, the ability of the Company to incur additional indebtedness, make
prepayments of certain indebtedness, pay dividends, make investments, engage in
transactions with stockholders and affiliates, issue capital stock of restricted
subsidiaries, create liens, sell assets and engage in mergers and
consolidations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources."

<PAGE>   11
 
NO ASSURANCE THAT GROWTH STRATEGY WILL BE ACHIEVED
 
     The successful implementation of the Company's one-way messaging services
strategy to increase cash flow through the expansion of its subscriber base is
necessary for the Company to meet its capital expenditures, working capital and
debt service requirements. The Company expects to continue to incur operating
losses for the next several years. The Company's strategy assumes that the
paging and one-way wireless messaging industry will continue to grow rapidly,
and that the Company will continue to grow substantially faster than the
industry. The Company does not expect to continue to grow at its historical
rate, and there can be no assurance that the Company will be able to achieve the
growth contemplated by its business strategy. If such growth is not achieved,
the Company may not be able to make required payments on its outstanding
indebtedness and may have to refinance its outstanding indebtedness in order to
repay such obligations. No assurance can be given that the Company will be able
to refinance its outstanding indebtedness. In addition, as the Company begins
development and implementation of two-way services, the Company expects to make
substantial additional capital expenditures and sustain significant operating
losses, which will require additional debt or equity financing from sources
which may include joint venture arrangements. There can be no assurance that
such financing will be available to the Company on reasonable terms, or at all.
The Company will incur significant expenses and make substantial investments
associated with its two-way services prior to the time any significant revenues
from such services are generated. See "-- Risks of Implementation and Financing
of Two-Way Services" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
COMPETITIVE MARKET
 
     The Company faces significant competition in all of its markets. Many of
the Company's competitors, which include regional and national paging companies
and certain regional telephone companies, possess significantly greater
financial, technical and other resources than the Company. If any of such
companies were to devote additional resources to the paging or other wireless
messaging businesses or focus its strategy on the Company's marketing and
product niches, the Company's results of operations could be adversely affected.
Some of these larger competitors may also be able to use their substantial
financial resources to increase the already substantial pricing competition in
the markets in which the Company operates, which may have an adverse effect on
the Company's results of operations. For competitive and marketing reasons, the
Company generally sells each new unit for less than its acquisition cost. In
addition, a number of paging carriers have constructed or are in the process of
constructing nationwide paging networks that offer services similar to the
Company's services, including the provision of two-way messaging. See
"Business -- Competition."
 
     Industry reports indicate, and the Company believes, that the retail
distribution of pagers has become increasingly common in the paging industry.
Retail distribution is a key element of the Company's business strategy. Retail
distributors have typically selected only one paging carrier for their stores,
and the Company faces competition in its efforts to place units through retail
distributors. If the Company is unable to maintain its current sales
relationships with retail distributors or obtain new sales relationships with
other retail distributors, it may not be able to achieve the growth contemplated
by its business strategy. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- General."
 
ADVERSE EFFECT OF SUBSCRIBER DISCONNECTIONS
 
     The results of operations of paging service providers such as the Company
are significantly affected by subscriber disconnections. In order to realize net
growth in units in service, disconnected users must be replaced, and additional
users must be added. However, the sales and marketing costs associated with
attracting new subscribers are substantial relative to the costs of providing
service to existing customers, and expenses associated with each new unit
placement exceed the sales price and service initiation fee received by the
Company. Because the paging business is characterized by high fixed costs,
disconnections directly and adversely affect operating income. In addition,
because the Company plans to sell an increasing number of its units through
retail distribution channels, the Company's overall rate of disconnections may
increase since the Company expects that subscribers who purchase pagers through
retail outlets will tend to cancel their subscriptions at a higher rate than
subscribers obtained through other distribution channels. The Company's
 
                                       11
<PAGE>   12
 
average monthly disconnection rates for the twelve months ended December 31,
1994, December 31, 1995 and March 31, 1996 were 3.4%, 2.5% and 2.4% per month,
respectively. An increase in its rate of disconnections would adversely affect
the Company's results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- General."
 
RISKS OF IMPLEMENTATION AND FINANCING OF TWO-WAY SERVICES
 
     In the FCC NPCS auctions, the Company acquired a total of 100 kHz of
forward frequency and 50 kHz of return frequency nationwide. Specifically, the
Company acquired a 50 kHz unpaired nationwide NPCS license (the "Nationwide
Narrowband License") and five 50/50 kHz paired regional NPCS licenses (the
"Regional Narrowband Licenses" or collectively, with the Nationwide Narrowband
License, the NPCS Licenses). These acquired licenses could be utilized to offer
two-way messaging services or, if two-way messaging services are not fully
implemented, to expand the Company's existing one-way transmission capacity.
 
     The development and implementation of two-way services will require the
application of new technology and the construction of a transmission network, in
addition to the network used in the Company's existing one-way messaging
business. Existing two-way wireless data services have had only limited market
acceptance. There can be no assurance that two-way services will be commercially
viable, and the success of two-way services could be affected by matters beyond
the Company's control such as the future cost of infrastructure and subscriber
equipment, technological changes in wireless messaging services, marketing and
pricing strategies of competitors, regulatory developments and general economic
conditions.
 
     Significant additional financing will be required to fund the construction
of a transmission network for two-way services, other start-up costs and selling
expenses. The Company anticipates investing $75 to $100 million through fiscal
1997 to test and construct a two-way transmission network. Thereafter, the
Company anticipates that its two-way operations may require up to $100 million
of additional investment to substantially complete the network buildout. The
Company expects to require additional financing to complete the buildout, which
may include entering joint venture arrangements, however there can be no
assurance that sufficient financing will be available to the Company. The
Company's ability to incur indebtedness is limited by the covenants contained in
the 15% Indenture, the 12 1/4% Indenture, the Vendor Purchase Financing
Agreement (as defined herein) and the Revolving Credit Agreement (as defined
herein) and as a result, any additional financing may need to be equity
financing. The Company does not anticipate any significant revenues from two-way
services during 1996 or 1997. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
DEPENDENCE ON KEY PERSONNEL
 
     The success of the Company will be dependent, to a significant extent, upon
the continued services of the key executive officers of the Company. The Company
does not have employment agreements with any of its current executive officers,
although all current executive officers have entered into non-competition
agreements with the Company. The loss or unavailability of one or more of its
executive officers or the inability to attract or retain key employees in the
future could have an adverse effect upon the Company's operations. See
"Management -- Directors and Executive Officers."
 
TECHNOLOGICAL CHANGES
 
     The telecommunications industry is characterized by rapid technological
change. Future technology advances in the industry may result in the
availability of new services or products that could compete directly with the
paging and other wireless messaging services that are currently provided or are
being developed by the Company. Changes in technology could also lower the cost
of competitive products and services to a level where the Company's products and
services become less competitive or the Company is required to reduce the prices
of its services. The Company expects to respond to technological changes by
continuing to make investments in new and improved systems and related service
capability.
 
                                       12
<PAGE>   13
 
     Several wireless two-way communication technologies, including cellular
telephone service, broadband personal communications services, specialized
mobile radio, low-speed data networks and mobile satellite services, are
currently in use or under development. Although these technologies are currently
more expensive than paging services or are not yet broadly available, future
implementation and technological improvements could result in increased capacity
and efficiency for wireless two-way communication and, accordingly, could result
in increased competition for the Company. Some of these service providers are
bundling paging services with two-way voice service in a combined handset. Large
manufacturers dominate technological development in the wireless communications
industry, and changes in their methods of distributing one-way wireless
messaging products could reduce the Company's access to technology and may have
an adverse effect on the Company's operations. There can be no assurance that
the Company will not be adversely affected by such technological change. See
"-- Dependence on Key Suppliers" and "Business -- Competition."
 
DEPENDENCE ON KEY SUPPLIERS
 
     The Company does not manufacture any of the pagers used in its paging
operations. The Company buys pagers primarily from Motorola, Inc. ("Motorola")
as well as some other manufacturers and therefore is dependent on such
manufacturers to obtain sufficient pager inventory for new subscriber and
replacement needs. In addition, the Company has acquired terminals and
transmitters primarily through vendor financing agreements with Motorola and
Glenayre Technologies, Inc. ("Glenayre") and thus is dependent on such
manufacturers for sufficient terminals and transmitters to meet its expansion
and replacement requirements. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources." There can be no assurance that the Company will not experience
significant delays in obtaining pagers, terminals or transmitters in the future.
The Company has never had a pager supply agreement with Motorola or any other
pager manufacturer and there can be no assurance that either Motorola or
Glenayre will enter into any new vendor financing agreements with the Company or
that the terms and conditions of any new agreement will be as favorable to the
Company as under past agreements. Although the Company believes that sufficient
alternative sources of pagers, terminals and transmitters exist, there can be no
assurance that the Company would not be adversely affected if it were unable to
obtain these items from current supply sources or on terms comparable to
existing terms.
 
POTENTIAL FOR CHANGE IN REGULATORY ENVIRONMENT
 
     The Company and the wireless communications industry are subject to
regulation by the FCC and various state regulatory agencies. Under prior law and
regulations, in situations involving mutually exclusive applications, FCC
licenses were issued through a system of lotteries and comparative hearings. The
Omnibus Budget Reconciliation Act of 1993 (the "Budget Act") amended the
Communications Act of 1934, as amended (the "Communications Act"), to authorize
the FCC to utilize a system of competitive auctions to issue licenses for the
use of frequencies for which there are mutually exclusive applications, where
the principal use of the license will be to offer service in return for
compensation from subscribers. Implementation of the auction procedures has made
expansion of the Company's operations more costly.
 
     The Budget Act also amended the Communications Act by eliminating many of
the regulatory distinctions governing mobile service providers. The FCC
implemented the new law by creating a new regulatory category called "commercial
mobile radio services" ("CMRS"), which includes most paging providers currently
operating as either radio common carriers ("RCCs") or private carrier paging
operators ("PCPs"), including the Company. The FCC has adopted new rules to
govern regulation of this new category, which will become effective in August
1996. As a result of the new rules, PCP licensees (such as the Company) will
have additional obligations beginning in August 1996. For example, these
licensees must provide connection upon reasonable request, must not engage in
any unreasonably discriminatory practices and will be subject to complaints
regarding any unlawful practices. PCP licensees will also be subject to
provisions that authorize the FCC to provide remedial relief to an aggrieved
party upon finding of a violation of the Communications Act and related consumer
protection provisions. In this regard, the FCC is currently considering certain
significant changes with respect to how paging is licensed and the ways in which
rates are determined for interconnection between local exchange carriers and
paging operators. See "Business -- Government Regulation."
 
                                       13
<PAGE>   14
 
     From time to time, legislation and regulations which could potentially
adversely affect the Company are proposed by federal and state legislators and
regulators. Legislation is currently in effect in Texas requiring paging
companies to contribute a portion of their taxable revenues to a
Telecommunications Infrastructure Fund created by the state legislature. See
"Business -- Government Regulation." Management does not believe that the Texas
law will have a material adverse affect on the Company's operations and is not
aware of any other currently pending legislation or regulations which will have
a material adverse impact on the Company's operations. However, there can be no
assurance that Federal or other state legislation will not be adopted, or that
the FCC or the various state agencies will not adopt regulations or take other
actions, that would adversely affect the business of the Company. See
"Business -- Government Regulation."
 
RESTRICTIONS ON FOREIGN OWNERSHIP
 
     Under existing law, except in extraordinary circumstances, no more than 25%
of the Company's capital stock may be owned, directly or indirectly, or voted by
non-U.S. citizens or their representatives, a foreign government or its
representatives, or a foreign corporation. See "Business -- Government
Regulation." If the foreign ownership of the Company were to exceed 25%, the FCC
could revoke the Company's FCC licenses if the FCC found the public interest
would be served by such revocation, although the Company could seek approval
from the FCC for the additional foreign ownership or take other actions to
reduce the Company's percentage of foreign ownership in order to avoid the loss
of its licenses. The Company's certificate of incorporation authorizes the Board
of Directors to cause the Company to redeem its equity securities owned by
foreigners at their then current market value (determined as set forth in the
certificate of incorporation) in order to ensure compliance with the rules,
regulations and policies of the FCC (the "FCC Rules"). Based on currently
available information, the Company estimates that its foreign ownership is
approximately 22%. However, this percentage is subject to change at any time
upon any transfer of direct or indirect ownership of the Company's Common Stock.
These restrictions on foreign ownership could also adversely affect the ability
of the Company to attract additional equity financing from entities that are, or
are owned by, non-U.S. persons.
 
RISKS OF INTERNATIONAL OPERATIONS
 
     The Company intends to continue to expand internationally. Recently, the
Company was successful in obtaining licenses for frequencies with its foreign
partners in Canada and the Bahamas. The Company may seek joint venture partners
in certain other countries, in particular where domestic regulations prohibit
foreign control of telecommunications companies. The Company will need to obtain
licenses for frequencies in any foreign country in which it seeks to expand and,
if the licenses are obtained, to construct or acquire a transmission network and
thereafter to begin sales and marketing efforts. However, there can be no
assurance that the Company will be able to obtain licenses in foreign countries,
that it will be successful in finding joint venture partners or that its foreign
operations, if established, will be profitable. Acquiring licenses, constructing
or acquiring a transmission network and commencing operations could require the
Company to provide funding for such operations and could require the Company to
seek additional debt or equity capital. In countries where the Company is or may
become a minority holder in a joint venture controlled by another party, such as
the Company's existing joint venture in Canada, the success of such joint
venture's operations will depend substantially on the efforts of the Company's
venture partner and may be impeded if disputes arise between the parties.
International operations are subject to various risks not present in domestic
operations such as fluctuations in currency exchange ratios, nationalization or
expropriation of assets, import/export controls, political instability,
variations in the protection of intellectual property rights, limitations on
foreign investment, restrictions on the ability to convert currency and the
additional expenses and risks inherent in conducting operations in
geographically distant locations, with customers speaking different languages
and having different cultural approaches to the conduct of business. To mitigate
the effects of foreign currency fluctuations on the results of its foreign
operations, the Company anticipates utilizing forward exchange contracts and
engaging in other efforts to hedge foreign currency transactions. However, there
can be no assurance as to the effectiveness of such mitigation efforts in
limiting any adverse effects of foreign currency fluctuations on the Company's
foreign operations and on the Company's overall results of operations. See
"Business -- International Expansion."

SIGNIFICANT OWNERSHIP
 
     The Morgan Stanley Shareholders currently own approximately 60.4% of the
outstanding Common Stock of the Company and approximately 48.9% of the
outstanding voting Common Stock. After giving effect to the Offering, the Morgan
Stanley Shareholders will own approximately 51.3% of the outstanding Common
Stock and 38.9% of the outstanding voting Common Stock (approximately 50.1% of
the outstanding Common Stock and 37.7% of the outstanding voting Common Stock if
the Underwriters' over-allotment option is exercised in full). The Morgan
Stanley Shareholders have informed the Company that they intend, upon the
consummation of the Offering, to convert such number of their shares of
non-voting Common Stock so that, following such conversion, the Morgan Stanley
Shareholders will own, in the aggregate, 49% of the outstanding voting Common
Stock of the Company. See "Principal Stockholders." The general partner and/or
the managing general partner of each of the general partner of the Morgan
Stanley Shareholders is a wholly-owned subsidiary of Morgan Stanley Group Inc.
("MS Group"). Four of the nine directors of the Company are employees of a
wholly-owned subsidiary of MS Group. As a result of its ownership interest in
the Company and certain rights pursuant to the Amended and Restated Agreement
among certain Stockholders dated as of May 10, 1996 (the "Stockholders
Agreement"), among the Morgan Stanley Shareholders, the Company and certain
other stockholders, the Morgan Stanley Shareholders have a significant influence
over the affairs of the Company. See "Certain Transactions."
 
POTENTIAL ADVERSE EFFECT ON MARKET PRICE BECAUSE OF SHARES ELIGIBLE FOR FUTURE
SALE
 
     Of the 39,713,226 shares of Class A Common Stock which will be outstanding
after consummation of the Offering, only the 6,000,000 shares being offered
hereby will be eligible for immediate resale in the public market without
restriction, except to the extent that any of such shares are acquired by an
affiliate of the Company. The future sale of a substantial number of shares of
Common Stock in the public market following the Offering, or the perception that
such sales could occur, could adversely affect the market price for Common
Stock. The Company has granted all the investors party to the Stockholders
Agreement certain registration rights with respect to the Common Stock owned by
these investors. If these investors should sell a substantial amount of such
Common Stock, the prevailing market price for the Common Stock could be
adversely affected. The Company, these investors and the officers and directors
of the Company have agreed not to sell any shares of the Common Stock, or any
securities convertible into or exercisable or exchangeable for Common Stock, for
a period of 180 days after the date of this Prospectus without the consent of
Morgan Stanley & Co. Incorporated ("MS & Co."). The Company intends to file a
registration statement to register up to 627,900 shares of Common Stock issuable
upon exercise of outstanding warrants and such shares will be eligible for
immediate resale in the public market after such registration statement becomes
effective. The agreement governing such warrants provides that the Company will
not cause such registration statement to become effective for a period of 180
days after the date of this Prospectus without MS & Co.'s prior written consent.
See "Shares Eligible for Future Sale."
 
ABSENCE OF PRIOR PUBLIC MARKET
 
     Prior to the Offering, there has been no public market for the Class A
Common Stock. Although the Class A Common Stock has been approved for trading on
the Nasdaq National Market ("Nasdaq"), subject to official notice of issuance,
there can be no assurance that an active public market for the Class A Common
Stock will develop and continue after the Offering or that the Class A Common
Stock offered hereby will trade at or above the initial public offering price.
MS & Co. will not act as a market-maker of the Class A Common Stock. See
"Underwriters."
 
ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BY-LAWS
AND DELAWARE LAW
 
     Certain provisions of the Company's Certificate of Incorporation, By-laws
and the Stockholders Agreement, as well as provisions of the Delaware General
Corporation Law, may have the effect of delaying or preventing transactions
involving a change of control of the Company, including transactions in which
stockholders might otherwise receive a substantial premium for their shares over
then current market prices, and may limit the ability of stockholders to approve
transactions that they may deem to be in their best interests. In particular,
under the certificate of incorporation, the Board of Directors is authorized to
issue one
 
                                       15
<PAGE>   16
 
or more classes of preferred stock having such designations, rights and
preferences as may be determined by the Board. See "Description of Capital
Stock."
 
POTENTIAL DILUTION OF VOTING POWER UPON CONVERSION INTO CLASS A COMMON STOCK
 
     As of March 31, 1996, there were 8,975,469 shares of Class B Common Stock
outstanding, 731,846 shares of Class C Common Stock outstanding and 725,445
shares of Class D Common Stock outstanding, representing, in the aggregate,
approximately 30.9% of the total outstanding Common Stock (26.3% after giving
effect to issuance of the Class A Common Stock offered hereby). Conversion of
shares of Class B Common Stock, Class C Common Stock or Class D Common Stock
into shares of Class A Common Stock would result in a decrease in the voting
power of the investors in the Class A Common Stock offered hereby, as well as
holders of the previously outstanding Class A Common Stock. After giving effect
to the Offering, if all such shares of Class B Common Stock, Class C Common
Stock and Class D Common Stock were so converted, the holders of such newly
converted Class A Common Stock would own approximately 26.3% of the outstanding
Class A Common Stock. Although shares of Class D Common Stock are freely
convertible into Class A Common Stock following the Offering, shares of Class B
Common Stock and Class C Common Stock are by their terms convertible into Class
A Common Stock only so long as the aggregate percentage of shares of Class A
Common Stock owned by certain holders remains below a certain level. See
"Description of Capital Stock -- Common Stock." The Morgan Stanley Shareholders
have informed the Company that any conversion of their shares of Class B Common
Stock into Class A Common Stock will be solely to maintain their current level
of ownership of voting Common Stock. See "Principal Stockholders."
 
DILUTION
 
     Investors in the Class A Common Stock offered hereby will experience an
immediate dilution of $15.38 per share in the net tangible book value of their
shares of Class A Common Stock. See "Dilution."
 
                                  THE COMPANY
 
     PageMart Wireless, Inc. ("Wireless") was incorporated in Delaware on
November 29, 1994 as a wholly-owned subsidiary of PageMart. Effective January
19, 1995, PageMart merged with a wholly-owned subsidiary of Wireless, pursuant
to which PageMart was the surviving corporation (the "Reorganization"). As part
of the Reorganization, each share of outstanding common stock of PageMart was
converted into the right to receive one share of Common Stock of Wireless. Upon
consummation of the Reorganization, the stockholders of PageMart had the same
ownership interest in Wireless as they had in PageMart, and Wireless owned all
of the capital stock of PageMart. On December 28, 1995, the name of the Company
was changed from PageMart Nationwide, Inc. to PageMart Wireless, Inc.
 
     The Company's executive offices are located at 6688 North Central
Expressway, Suite 800, Dallas, Texas 75206, its telephone number is (214)
750-5809 and its fax number is (214) 987-2029.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the Class A Common Stock
offered hereby are estimated to be approximately $70.9 million ($81.7 million if
the Underwriters' over-allotment option is exercised in full), after deducting
estimated underwriting discounts and commissions and estimated fees and expenses
of the Offering. The Company expects to use the proceeds of the Offering as
follows: approximately $50 million to fund the initial construction of the
Company's NPCS transmission network and approximately $13 million for the
retirement of the Company's vendor debt, with the balance to be used to repay
approximately $8 million of loans expected to be outstanding under the Company's
revolving credit facility and for other general corporate purposes. At March 31,
1996, there were no amounts outstanding under the revolving credit facility. The
Company expects to borrow up to $8 million under the revolving credit facility
subsequent to March 31, 1996 in order to fund working capital requirements and
capital expenditures associated with the Company's one-way messaging operations.
The weighted average cost of vendor debt at March 31, 1996 was 13.2%, and such
debt matures on various dates through 2000. The weighted average cost of
borrowings under the Company's revolving credit facility at March 31, 1996 was
9.5%, and amounts outstanding under the Revolving Credit Agreement mature on
March 31, 1999. The Company anticipates investing $75 to $100 million through
fiscal 1997 to test and construct a two-way transmission network.
 
                                       16
<PAGE>   17
 
Thereafter, the Company anticipates that its two-way operations may require up
to $100 million of additional investment to substantially complete the network
buildout. See "Risk Factors -- Risk of Implementation and Financing of Two-Way
Services" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     The Company has not paid dividends on the Common Stock since its
organization in 1989. The Company currently intends to retain future earnings
for the development of its business and does not anticipate paying cash
dividends on its Common Stock in the foreseeable future. The Company's future
dividend policy will be determined by its Board of Directors on the basis of
various factors, including the Company's results of operations, financial
condition, capital requirements and investment opportunities. In addition, the
Company's debt instruments substantially restrict (and currently prohibit) the
payment of cash dividends.
 
                                    DILUTION
 
     The deficit in net tangible book value of the Company as of March 31, 1996
was $165.5 million or $4.91 per share of outstanding Common Stock. After giving
effect to the sale of 6,000,000 shares of Class A Common Stock offered hereby,
the pro forma deficit in net tangible book value of the Company as of March 31,
1996 would have been approximately $94.6 million or $2.38 per share,
representing an immediate dilution of $15.38 per share to investors purchasing
shares in the Offering. The following table illustrates this per share dilution.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This discussion should be read in conjunction with the Company's
Consolidated Financial Statements and the notes thereto included elsewhere in
this Prospectus.
 
GENERAL
 
     The Company has constructed and operates a wireless messaging and
communications network and provides paging and other one-way wireless messaging
services to its subscribers. In addition, the Company sells and distributes
wireless messaging equipment to subscribers, retailers and resellers. The
Company earns recurring revenues from each subscriber in the form of fixed
periodic fees and incurs substantial operating expenses in offering its
services, including technical, customer service and general and administrative
expenses. See "-- Management's Presentation of Results of Operations."
 
     Since commencing operations in 1990, the Company has invested heavily in
its wireless communications network and administrative infrastructure in order
to establish nationwide coverage, sales offices in major metropolitan areas,
customer service call centers and centralized administrative support functions.
The Company incurs substantial fixed operating costs related to its one-way
wireless communications infrastructure, which is designed to serve a much larger
subscriber base than the Company currently serves in order to accommodate
growth. In addition, the Company incurs substantial costs associated with new
subscriber additions. As a result, the Company has generated significant net
operating losses for each year of its operations. See "-- Management's
Presentation of Results of Operations."
 
     The Company's strategy is to expand its subscriber base as rapidly as
possible to increase cash flow through greater utilization of its nationwide
wireless communications network. From January 1, 1992 to March 31, 1996, the
number of units in service increased from 52,125 to 1,374,146. None of the
Company's growth is attributable to acquisitions. Given its growth strategy and
the substantial associated selling and marketing expenses, the Company expects
to continue to generate operating losses in 1996 from its one-way wireless
communications business. In addition, the Company plans to begin development and
implementation of two-way wireless messaging services during 1996, and expects
to incur additional operating losses during the start-up phase for such
services. The Company does not anticipate any significant revenues from two-way
services during 1996 or 1997, however it expects to generate significant
revenues with respect to two-way services in 1998. See "Risk Factors -- Risks of
Implementation and Financing of Two-Way Services." The Company's ability to
generate operating income is primarily dependent on its ability to attain a
sufficiently large installed subscriber base that generates recurring revenues
which offset the fixed operating costs of its wireless networks, administration
and selling and marketing expenses. The Company intends to achieve this growth
by promoting its customized paging and other wireless messaging services through
its national sales offices, retail distribution channels, private brand
strategic alliances with GTE Corporation ("GTE"), Southwestern Bell Mobile
Systems ("SBMS"), AT&T Wireless Services ("AT&T Wireless"), Ameritech Mobile
Services, Inc. ("Ameritech") and long distance reseller EXCEL
Telecommunications, Inc. ("Excel"), and international expansion.
 
     Unlike most other paging carriers, the Company sells, rather than leases,
substantially all of the messaging equipment used by its subscribers. As a
result, the Company has much less capital invested in messaging equipment than
other paging carriers since it recoups a substantial portion of messaging
equipment costs upon sale to retailers and subscribers. This results in
significantly lower capital expenditures, depreciation and amortization than if
the Company leased such equipment to its subscribers. In addition, the Company's
financial results are much different than other paging carriers that lease
messaging equipment to subscribers because the Company recognizes the cost of
messaging equipment sold in connection with adding new subscribers at the time
of sale rather than capitalizing and depreciating the cost of messaging
equipment over periods ranging from three to five years as occurs with paging
carriers that lease messaging equipment to subscribers. However, the Company
expects to lease rather than sell a portion of its two-way messaging units. In
addition, the Company's retail distribution strategy results in the recognition
of expenses associated with
 
                                       21
<PAGE>   22
 
messaging equipment sales and other sales and marketing expenses in advance of
new subscribers being added to the base and generating revenues (as retailers
carry inventory).
 
     The Company sells its messaging equipment through multiple distribution
channels including direct sales, third-party resellers, private brand strategic
alliances and local and national retail stores. Selling and marketing expenses
are primarily attributable to compensation paid to the Company's sales force,
advertising and marketing costs and to losses resulting from the fact that, for
competitive and marketing reasons, the Company generally sells each new unit for
less than its acquisition cost. The Company's accounting practices result in
selling and marketing expenses, including loss on sale of equipment, being
recorded at the time a unit is sold. Units sold by the Company during a given
month may exceed units activated and in service due to inventory stocking and
distribution strategies of the retailers. As a result, selling and marketing
expenses per net subscriber addition may fluctuate from period to period. In
general, the Company anticipates that, based on its recent experience, 90% of
its units sold through retail distribution channels will be activated and in
service within 75 days of shipment.
 
     The Company derives its recurring revenue primarily from fixed periodic
fees for services that are not generally dependent on usage. Consequently, the
Company's ability to recoup its initial selling and marketing costs, to meet
operating expenses and to achieve profitability is dependent on the average
length of each customer's subscription period. As long as a subscriber continues
to utilize the Company's service, operating results benefit from the recurring
payments of the fixed fees without the incurrence of additional selling expenses
by the Company. Conversely, operating results are adversely affected by customer
disconnections. Each month a percentage of the Company's existing customers have
their service terminated for a variety of reasons, including failure to pay,
dissatisfaction with service and switching to a competing service provider. The
Company's average monthly disconnection rates for the twelve months ended
December 31, 1993, 1994, 1995 and March 31, 1996 were 3.7%, 3.4%, 2.5% and 2.4%,
respectively.
 
     More than 90% of the Company's ARPU is attributable to fixed fees for
airtime, coverage options and features. A portion of the remainder of additional
ARPU is dependent on usage.
 
RESULTS OF OPERATIONS
 
     The Company's principal operations to date are its domestic one-way
wireless messaging division. The following discussion of results of operations
analyzes the results of the Company's one-way wireless messaging operations,
unless otherwise indicated.
 
     Certain of the following financial information is presented on a per unit
basis. Management of the Company believes that such a presentation is useful in
understanding the Company's results because it is a meaningful comparison period
to period given the Company's growth rate and the significant differences in the
number of subscribers of other paging companies.
 
  THREE MONTHS ENDED MARCH 31, 1995 AND 1996
 
     Units in Service
 
     Units in service were 874,944 and 1,374,146 as of March 31, 1995 and 1996,
respectively, representing an annual growth rate of 57%. The Company has
experienced strong growth in units in service due primarily to the success of
its sales and marketing strategies in the direct sales, national retail and
third-party reseller channels, as well as from private brand strategic alliance
programs.
 
     Revenues
 
     Revenues for the three months ended March 31, 1995 and 1996 were $32.7
million and $48.5 million, respectively. Recurring revenues for airtime,
voicemail and other services for the same periods were $20.5 million and $33.7
million, respectively. Revenues from equipment sales and activation fees for the
three months ended March 31, 1995 and 1996 were $12.2 million and $14.8 million,
respectively. The increases in recurring revenues and revenues from equipment
sales and activation fees were primarily due to the rapid growth in the number
of units in service. The increase in equipment sales during the first quarter of
1996 was
 
                                       22
<PAGE>   23
 
somewhat offset by a decline in the average price per unit sold. The Company
expects equipment prices per unit generally to remain constant or decline only
slightly as sales volumes increase.
 
     The Company's ARPU was $8.28 and $8.61 in the first quarter of 1995 and
1996, respectively. In general, over the past twelve months the Company's ARPU
has increased primarily as a result of an increase in subscribers added through
retail and direct sales channels. In addition, a portion of the increase in ARPU
from the first quarter of 1995 to the first quarter of 1996 was due to a higher
mix of multi-city, regional and nationwide services as well as increased sales
of other value-added services such as voicemail and toll free numbers.
Management anticipates that the Company's ARPU will decline in the foreseeable
future due to increased competition and a higher mix of subscribers added
through private brand strategic alliance programs and third-party resellers,
both of which yield lower ARPU. ARPU is lower for subscribers added through
third-party resellers and private brand strategic alliances because these are
generally high volume customers that are charged reduced airtime rates. However,
because third-party resellers and private brand strategic alliance partners are
responsible for selling and marketing costs, billing, collection and other
administrative costs associated with end-users, the Company does not incur these
costs with respect to such subscribers.
 
     Cost of Equipment Sold
 
     The cost of equipment sold for the three months ended March 31, 1995 and
1996 was $13.4 million and $17.1 million, respectively. The increase was
directly related to the increase in the number of units sold partially offset by
lower average pager prices paid to suppliers. The Company expects pager costs
generally to remain constant, with only modest reductions in cost to the Company
as a result of volume purchases. Management anticipates that loss on equipment
sold will increase on a per unit basis for the foreseeable future due to
increased competition.
 
     Operating Expenses
 
     Technical expenses were $5.5 million and $8.1 million for the three months
ended March 31, 1995 and 1996, respectively. The increase resulted primarily
from the expansion of the Company's nationwide network infrastructure, which
resulted in greater expenses associated with the addition of new transmitter
sites, transmitter and terminal equipment and telecommunications expenses. On an
average monthly cost per unit in service basis, technical expenses were $2.21
and $2.06 in the first quarter of 1995 and 1996, respectively. The per unit
decrease was the result of increased operating efficiencies and economies of
scale experienced with the growth of the Company's subscriber base. During the
three months ended March 31, 1996, the Company incurred $147,000 in technical
expenses associated with the development of its two-way wireless messaging
services.
 
     Selling expenses for the three months ended March 31, 1995 and 1996 were
$8.6 million and $9.4 million, respectively. This increase resulted from greater
marketing and advertising costs related to the significant growth in units sold
as well as from increased sales compensation because of the addition of sales
personnel in new and existing operating markets. During the first quarter of
1995 and 1996, the Company added 102,214 and 134,122 net new units in service,
respectively. Sales and marketing employees increased from 338 at March 31, 1995
to 486 at March 31, 1996. Management believes the net loss on equipment sold to
be a component of selling and marketing expenses incurred to add new subscribers
because the Company sells, rather than leases units to new subscribers. See
"-- Management's Presentation of Results of Operations." Selling and marketing
expenses per net subscriber addition (including loss on equipment sales) were
$95 and $86 for the three months ended March 31, 1995 and 1996, respectively.
During the three months ended March 31, 1996 the Company incurred $126,000 in
selling expenses associated with its international operations.
 
     General and administrative expenses (including costs associated with
customer service, field administration and corporate headquarters) in the first
quarter of 1995 and 1996 were $9.7 million and $12.9 million, respectively. This
increase was attributable to the Company's expansion of its customer service
call centers and continued expansion into new markets to support the growing
subscriber base which required additional office space, administrative personnel
and customer service representatives. The Company increased the
 
                                       23
<PAGE>   24
 
number of representatives in its customer service call centers from 389 on March
31, 1995 to over 575 on March 31, 1996, and believes it operates one of the most
extensive of such facilities in the paging industry. On an average cost per
month per unit in service basis, general and administrative expenses were $3.92
and $3.29 in the first quarter of 1995 and 1996, respectively. The per unit
decrease was a result of increased operating efficiencies and economies of scale
achieved through the growth of the Company's subscriber base. During the three
months ended March 31, 1996, the Company incurred $127,000 in general and
administrative expenses associated with the development of its two-way wireless
messaging services.
 
     Depreciation and amortization for the three months ended March 31, 1995 and
1996 was $2.8 million and $4.2 million, respectively. The increase resulted from
the expansion of the Company's network infrastructure including transmitter and
terminal equipment, as well as the purchase and development of a new centralized
administrative system during 1995 and the first three months of 1996. As an
average cost per month per unit in service, depreciation and amortization was
$1.13 and $1.08 for the three months ended March 31, 1995 and 1996,
respectively.
 
     Interest Expense
 
     Interest expense increased from $6.7 million in the first quarter of 1995
to $8.4 million in the first quarter of 1996. The increase in 1996 was primarily
the result of increased interest expense related to the 15% Notes and the
12 1/4% Notes. Interest expense related to the 12 1/4% Notes was $2.8 million
and $3.2 million in the first quarter of 1995 and 1996, respectively. Interest
expense related to the 15% Notes was $3.2 million and $4.4 million in the first
quarter of 1995 and 1996, respectively.
 
     Net Loss
 
     The Company sustained net losses in the first quarter of 1995 and 1996 of
$13.7 million and $11.6 million, respectively, principally due to the cost of
funding the growth rate of the Company's subscriber base which resulted in an
increase in units sold, selling and marketing expenses, operating expenses and
interest expense.
 
  FISCAL YEARS 1993, 1994 AND 1995
 
     Units in Service
 
     Units in service were 327,303, 772,730 and 1,240,024 as of December 31,
1993, 1994 and 1995, respectively. This represents a growth rate of 136% and 60%
in 1994 and 1995, respectively. The Company has experienced strong growth in
units in service due primarily to the success of its sales and marketing
strategies in the direct sales, national retail and third-party reseller
channels, as well as from private brand strategic alliance programs. According
to industry sources, the paging industry in general has experienced growth rates
of 29%, 38% and 25% for 1993, 1994 and 1995, respectively.
 
     Revenues
 
     Revenues for the fiscal years 1993, 1994 and 1995 were $50.7 million,
$109.8 million and $159.2 million, respectively. Recurring revenues for airtime,
voicemail and other services for the same periods were $24.2 million, $56.6
million and $101.5 million, respectively. Revenues from equipment sales and
activation fees for 1993, 1994 and 1995 were $26.5 million, $53.2 million and
$57.7 million, respectively. The increases in recurring revenues and revenues
from equipment sales and activation fees were primarily due to rapid growth in
the number of units in service. The increase in equipment sales during 1995 was
somewhat offset by a decline in the average price per unit sold.
 
     The Company's ARPU was $9.81, $8.64 and $8.62 in the final quarter of 1993,
1994 and 1995, respectively. The Company's ARPU declined in 1994 and 1995
primarily as a result of an increase in subscribers added through third-party
resellers and distribution through private brand strategic alliance programs.
The decrease in 1995 was slightly offset by a higher mix of multi-city, regional
and nationwide services as well as increased sales of other value-added services
such as voicemail and toll free numbers.
 
                                       24
<PAGE>   25
 
     Cost of Equipment Sold
 
     The cost of equipment sold in 1993, 1994 and 1995 was $28.2 million, $57.8
million and $64.0 million, respectively. The increase was directly related to
the increase in the number of units sold partially offset by lower average pager
prices paid to suppliers.
 
     Operating Expenses
 
     Technical expenses were $9.5 million, $16.2 million and $25.7 million in
1993, 1994 and 1995, respectively. The increase resulted primarily from the
expansion of the Company's nationwide network infrastructure, which resulted in
greater expenses associated with the addition of new transmitter sites,
transmitter and terminal equipment and telecommunications expenses. On an
average monthly cost per unit in service basis, technical expenses were $3.55,
$2.45 and $2.13 in 1993, 1994 and 1995, respectively. The per unit decreases
were the result of increased operating efficiencies and economies of scale
experienced with the growth of the Company's subscriber base. During 1995, the
Company incurred $222,000 in technical expenses associated with the development
of its two-way wireless messaging services.
 
     Selling expenses in 1993, 1994 and 1995 were $17.3 million, $31.3 million
and $36.1 million, respectively. This increase resulted from greater marketing
and advertising costs related to the significant growth in units sold as well as
from increased sales compensation because of the addition of sales personnel in
new and existing operating markets. During the years ended December 31, 1993,
1994 and 1995, the Company added 210,269, 445,427 and 467,294 net new units in
service, respectively. Sales and marketing employees increased from 305 at
December 31, 1993 to 450 at December 31, 1994 and then decreased to 445 at
December 31, 1995. Management believes the net loss on equipment sold to be a
component of selling and marketing expenses incurred to add new subscribers. See
"-- Management's Presentation of Results of Operations." Selling and marketing
expenses per net subscriber addition (including loss on equipment sales) were
$91, $81 and $91 for the years ended December 31, 1993, 1994 and 1995,
respectively. The increase in 1995 was due to the addition of new sales offices,
expansion of existing sales offices and an increase in the number of retail
stores supported by the Company's marketing organization.
 
     General and administrative expenses (including costs associated with
customer service, field administration and corporate headquarters) in 1993, 1994
and 1995 were $15.6 million, $29.8 million and $43.5 million, respectively. This
increase was attributable to the Company's expansion of its customer service
call centers and continued expansion into new markets to support the growing
subscriber base which required additional office space, administrative personnel
and customer service representatives. The Company increased the number of
representatives in its customer service call centers from 69 on December 31,
1993 to 389 on December 31, 1994 and to 600 on December 31, 1995, and believes
it operates one of the most extensive of such facilities in the paging industry.
On an average cost per month per unit in service basis, general and
administrative expenses were $5.84, $4.52 and $3.60 in 1993, 1994 and 1995,
respectively. The per unit decreases were a result of increased operating
efficiencies and economies of scale achieved through the growth of the Company's
subscriber base. During 1995, the Company incurred $154,000 in general and
administrative expenses associated with the development of its two-way wireless
messaging services.
 
     Depreciation and amortization in 1993, 1994 and 1995 was $5.1 million, $8.1
million and $13.3 million, respectively. The increases resulted from the
expansion of the Company's network infrastructure including transmitter and
terminal equipment, as well as the purchase and development of a new centralized
administrative system in 1995. As an average cost per month per unit in service,
depreciation and amortization was $1.91, $1.23 and $1.10 for the years ended
December 31, 1993, 1994 and 1995, respectively.
 
     Interest Expense
 
     Interest expense increased from $6.5 million in 1993 to $12.9 million in
1994 and $30.7 million in 1995. The increase in 1994 was due to interest related
to the 12 1/4% Notes, partially offset by decreased borrowings under vendor
financing agreements. The increase in 1995 was primarily the result of the
issuance of the 15% Notes in January 1995, increased interest related to the
12 1/4% Notes, as well as increased borrowings under vendor financing
agreements. Interest expense related to the 12 1/4% Notes was $2.0 million,
$10.8 mil-
 
                                       25

lion and $11.8 million in 1993, 1994 and 1995, respectively. Interest expense
related to the 15% Notes was $15.3 million in 1995.
 
     Net Loss
 
     The Company sustained net losses in 1993, 1994 and 1995 of $31.1 million,
$45.8 million and $53.1 million, respectively, principally due to the cost of
funding the growth rate of the Company's subscriber base which resulted in an
increase in units sold, selling and marketing expenses, operating expenses and
interest expense.
 
MANAGEMENT'S PRESENTATION OF RESULTS OF OPERATIONS
 
  COMPARISON WITH GAAP PRESENTATION
 
     The Company's audited Consolidated Financial Statements for the years ended
December 31, 1993, 1994 and 1995, included elsewhere in this Prospectus, have
been prepared in accordance with GAAP. For internal management purposes the
Company prepares statements of operations that are derived from the Company's
GAAP financial statements but are reordered in a format that management uses for
its internal review of the Company's performance and that management believes
are useful in understanding the Company's results.
 
     Management believes that operating profit before selling expenses is a
meaningful indicator of the profitability of the Company's installed base of
units in service because it measures the recurring revenues received for
services less the costs (including depreciation and amortization) associated
with servicing that installed base. Operating profit before selling expenses per
subscriber per month for the Company's one-way operations has grown from $.33
during the second quarter of 1994 to $2.23 during the first quarter of 1996 due
primarily to the Company's increase in subscribers, operating efficiency and
resulting benefits in economies of scale.
 
     Separately, selling and marketing expenses (including loss on equipment
sold) provide a measure of the costs associated with obtaining new subscribers
that the Company needs to generate the incremental recurring revenue necessary
to achieve profitability. Under the GAAP presentation, recurring revenues and
equipment and activation revenues are aggregated and are not separately compared
to the costs associated with each.
 
     The items included in management's presentation of the results of
operations and their derivation from financial information presented in
accordance with GAAP are described below.
 
          Recurring Revenues. Recurring revenues include periodic fees for
     airtime, voicemail, customized coverage options, toll free numbers, excess
     usage fees and other recurring revenues and fees associated with the
     subscriber base. Recurring revenues do not include equipment sales revenues
     or initial activation fees. Recurring revenues are the same under both the
     management and GAAP presentations.
 
          Service Expenses. Service expenses under the management presentation
     include technical, customer service, general and administrative and
     headquarters expenses, but do not include selling and marketing expenses,
     depreciation or amortization.
 
          Depreciation and Amortization. This item is the same under the
     management and GAAP presentations.
 
          Operating Profit Before Selling Expenses. Operating profit before
     selling expenses under the management presentation is equal to recurring
     revenues less service expenses and depreciation and amortization. Operating
     profit before selling expenses is not derived pursuant to GAAP.
 
          Selling Expenses. Selling expenses under the management presentation
     represent the cost to the Company of selling pagers and other messaging
     units to a customer, and are equal to selling costs (sales compensation,
     advertising, marketing, etc.) plus costs of units sold less revenues from
     equipment sales and activation fees. As described above, the Company sells
     rather than leases substantially all of the one-way messaging equipment
     used by subscribers. Selling expenses under the management presentation are
     not derived pursuant to GAAP. Net loss on equipment sales is not included
     in the GAAP presentation of selling expenses.
 
                                       26
<PAGE>   27
 
          Operating Income (Loss). This item is the same under the management
     and GAAP presentations.
 
          EBITDA. EBITDA represents earnings (loss) before interest, taxes,
     depreciation and amortization. EBITDA is a financial measure commonly used
     in the paging industry. EBITDA is not derived pursuant to GAAP and
     therefore should not be construed as an alternative to operating income, as
     an alternative to cash flows from operating activities (as determined in
     accordance with GAAP) or as a measure of liquidity. The calculation of
     EBITDA does not include the commitments of the Company for capital
     expenditures and payment of debt and should not be deemed to represent
     funds available to the Company. In the fourth quarter of 1995, the
     Company's EBITDA from its one-way operations became positive for the first
     time.
 
  Selected Quarterly Results of Operations
 
     The table below sets forth management's presentation of results of one-way
domestic operations and other data on a quarterly basis for the eight most
recent fiscal quarters. This presentation should be read in conjunction with the
Consolidated Financial Statements of the Company and the notes thereto included
elsewhere in this Prospectus, and should not be considered in isolation or as an
alternative to results of operations that are presented in accordance with GAAP.

SEASONALITY
 
     Pager usage is slightly higher during the spring and summer months, which
is reflected in higher incremental usage fees earned by the Company. The
Company's retail sales are subject to seasonal fluctuations that affect retail
sales generally. Otherwise, the Company's results are generally not
significantly affected by seasonal factors.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's operations require substantial capital investment for the
development and installation of its wireless communications network, the
procurement of messaging equipment and expansion into new markets. To date,
these investments by the Company have been funded by the proceeds from the
issuance of common stock, preferred stock, the 12 1/4% Notes and the 15% Notes,
as well as borrowings under vendor financing agreements.
 
     Capital expenditures were $10.8 million, $16.7 million and $33.5 million
for the years ended December 31, 1993, 1994 and 1995, respectively and $11.8
million for the three months ended March 31, 1996. Capital expenditures for 1995
include approximately $8.7 million for the development of the Company's new
administrative system and approximately $1.0 million related to the development
of two-way messaging services. Capital expenditures for the first quarter of
1996 include approximately $223,000 related to the development of two-way
messaging services. The Company's expansion of its one-way wireless
communications network and related administrative facilities will require
capital expenditures currently estimated to be an
 
                                       28
<PAGE>   29
 
additional $18 million during 1996. During December 1995, the Company committed
to purchase $40 million in network infrastructure equipment from a significant
vendor from December 1, 1995 to October 31, 1999 (the "Vendor Commitment").
 
     The Company's net cash used in operating activities was $23.2 million,
$25.5 million and $2.9 million for the years ended December 31, 1993, 1994 and
1995, respectively, and the Company's operating activities provided net cash of
$366,000 for the three months ended March 31, 1996. The decrease in 1995 and the
improvement for the first quarter of 1996 was a result of improved operating
results from a larger subscriber base and higher efficiencies in working capital
achieved through improved collections procedures and improved inventory
management. Net cash used in investing activities was $18.6 million, $69.1
million and $110.2 million for the years ended December 31, 1993, 1994 and 1995
respectively, and $11.8 million for the three months ended March 31, 1996. The
increase in 1994 over 1993 was primarily due to the $58.9 million used for the
acquisition of the NPCS Licenses. Of the $110.2 million used in investing
activities in 1995, $74.1 million was for the acquisition of the NPCS Licenses
and the remainder was primarily for capital expenditures. Net cash provided by
financing activities, including proceeds from borrowings and issuances of common
and preferred stock was $61.8 million, $83.5 million and $125.5 million for the
years ended December 31, 1993, 1994 and 1995, respectively, and net cash used by
financing activities was $1.3 million for the three months ended March 31, 1996.
The increase in 1994 resulted from the $76.9 million of net proceeds from the
sale of stock (the "1994 Stock Offerings"). The increase in 1995 resulted
primarily from the $100.1 million of net proceeds from the sale of units,
consisting in the aggregate of $207.3 million principal amount at maturity of
the 15% Notes and 725,445 shares of Common Stock, and $24.5 million of net
proceeds from the sale of Common Stock (the "1995 Private Stock Offering").
Long-term obligations, less current maturities, increased by approximately $5.8
million during the three months ended March 31, 1996, $126.7 million during 1995
and $14.3 million during 1994. Net increases in borrowings were $47.3 million,
$16.5 million and $128.7 million for the years ended 1993, 1994 and 1995,
respectively. The net increase in 1994 resulted primarily from the accretion of
the 12 1/4% Notes and borrowings under vendor financing agreements. The
increases in 1995 and the first quarter of 1996 resulted from the issuance of
the 15% Notes, the accretion of the 12 1/4% Notes and borrowings under vendor
financing agreements.
 
     As of March 31, 1996, the Company's indebtedness under vendor financing
agreements was $13.7 million, its indebtedness under the 12 1/4% Notes was $98.0
million and its indebtedness under the 15% Notes was $119.1 million.
 
     The 12 1/4% Notes, which are unsecured senior obligations of PageMart,
mature in 2003 and were issued at a substantial discount from their principal
amount at maturity. The accretion of original issue discount on the 12 1/4%
Notes will cause an increase in indebtedness from March 31, 1996 to November 1,
1998 of $38.5 million. From and after November 1, 1998, interest on the 12 1/4%
Notes will be payable semiannually, in cash.
 
     The 15% Notes, which are unsecured senior obligations of Wireless, mature
in 2005 and were issued at a substantial discount from their principal amount at
maturity. The accretion of original issue discount on the 15% Notes will cause
an increase in indebtedness from March 31, 1996 to February 1, 2000 of $88.1
million. From and after February 1, 2000, interest on the 15% Notes will be
payable semiannually, in cash.
 
     In 1992, PageMart entered into an equipment lease agreement with Glenayre
(the "Vendor Lease Financing Agreement"), providing for the financing of
transmitter equipment up to a maximum aggregate amount of $15 million, pursuant
to lease term schedules mutually agreed upon for lease terms not exceeding 60
months. The Vendor Lease Financing Agreement is not a revolving line of credit
and the vendor's commitment expired on December 31, 1995. PageMart has an
option, at the expiration of any schedule to purchase all of the equipment
leased under that schedule at a nominal purchase price. The weighted average
interest rate in effect on March 31, 1996 with respect to the Vendor Lease
Financing Agreement was 13.49%. All outstanding indebtedness under the Vendor
Lease Financing Agreement will be repaid with a portion of the net proceeds from
the Offering.
 
                                       29
<PAGE>   30
 
     In May 1994, PageMart entered into a vendor purchase financing agreement
with Motorola (the "Vendor Purchase Financing Agreement"), providing for the
financing of transmitter equipment over a period of up to 36 months after the
acquisition of such equipment up to a maximum aggregate amount of $8 million.
The Vendor Purchase Financing Agreement is not a revolving line of credit. The
interest rate applicable to such financing is 4% above the prime rate quoted in
The Wall Street Journal from time to time. The weighted average interest rate in
effect on March 31, 1996 with respect to the Vendor Purchase Financing Agreement
was 12.5%.
 
     In May 1995, the Company entered into a four year Revolving Credit
Agreement (the "Revolving Credit Agreement") with BT Commercial Corporation, as
Agent, and Bankers Trust Company, as Issuing Bank, which provides for a $50
million revolving line of credit. Currently there are no loans outstanding under
the Revolving Credit Agreement. The maximum amount available under the Revolving
Credit Agreement at any time is limited to a borrowing base amount equal to the
lesser of (i) 80% of eligible accounts receivable plus 50% eligible inventory
owned by Wireless, and (ii) an amount equal to the service contribution (as
defined in the Revolving Credit Agreement) of Wireless and its subsidiaries for
the immediately preceding three-month period times 4.0. As of March 31, 1996,
the amount available under the Revolving Credit Agreement was $22.7 million.
 
     The Vendor Purchase Financing Agreement, the 12 1/4% Indenture, the 15%
Indenture and the Revolving Credit Agreement contain certain restrictive
covenants that, among other things, limit the ability of the Company to incur
indebtedness, pay dividends, repurchase capital stock, engage in transactions
with stockholders and affiliates, create liens, sell assets, enter into leases
and engage in mergers and consolidations, and the Revolving Credit Agreement
requires the Company to maintain certain financial ratios and limits the ability
of the Company to make capital expenditures. In addition, the 12 1/4% Indenture
prohibits PageMart from paying any dividends or making other distributions on
its capital stock, making loans to Wireless, merging or consolidating with
Wireless or assuming or guaranteeing any obligations of Wireless unless PageMart
is in compliance with certain interest coverage ratios and certain other
requirements. PageMart may, however, sell assets to Wireless in transactions
that are arm's-length in nature. Wireless is currently a holding company with no
business or operations of its own. Because all of Wireless's operations are
conducted through its subsidiaries, Wireless's cash flow and consequently its
ability to service debt, is almost entirely dependent upon the earnings of its
subsidiaries and the distribution of those earnings or upon loans or other
payment of funds by those subsidiaries to Wireless. Wireless's subsidiaries are
separate and distinct legal entities and have no obligation, contingent or
otherwise, to pay any amounts due pursuant to Wireless's obligations or to make
any funds available therefor, whether by dividends, loans or other payments.
Until the maturity of the 12 1/4% Notes, which mature on November 1, 2003, and
the indebtedness under the Vendor Purchase Financing Agreement, earlier
repayment of such indebtedness or compliance with the requirements of such debt
instruments, Wireless will be unable to use any amount of cash generated by the
operations of PageMart and its subsidiaries. However, currently Wireless does
not have significant cash requirements until August 2000 when interest on the
15% Notes must be paid in cash. See "Risk Factors -- High Leverage;
Stockholders' Deficit; Restrictive Covenants."
 
     On November 15, 1995, the Company purchased through PageMart International,
Inc., 200,000 shares of voting common stock of PageMart Canada, which represents
20% of the ownership of PageMart Canada. PageMart International, Inc. also owns
33% of the voting common stock of Canada Holding, which owns the remaining 80%
of the voting common stock of PageMart Canada. The Company's investment in
Canada Holding and PageMart Canada totals approximately $3.7 million.
 
     As of March 31, 1996, the Company had approximately $14.2 million in cash
and cash equivalents. The Company's cash balances, existing vendor financing
arrangements and borrowings under the Revolving Credit Agreement are expected to
be sufficient to fund the Company's one-way operations and related capital and
debt service requirements through 1997. See "Risk Factors -- No Assurance that
Growth Strategy will be Achieved."
 
     Significant additional financing will be required to fund the construction
of a transmission network for two-way services and other start-up costs and
selling and marketing expenses associated with the development and
implementation of two-way services. The Company anticipates investing $75 to
$100 million through
 
                                       30
<PAGE>   31
 
fiscal 1997 to test and construct a two-way transmission network. Thereafter,
the Company anticipates that the two-way operations may require up to $100
million of additional investment to substantially complete the network buildout.
The Company expects to require additional financing to complete the buildout
which may include entering into joint venture arrangements, however there can be
no assurance that sufficient financing will be available to the Company. The
Company's ability to incur indebtedness is limited by the covenants contained in
the 15% Indenture, the 12 1/4% Indenture, the Revolving Credit Agreement and the
Vendor Purchase Financing Agreement, and as a result any additional financing
may need to be equity financing. See "Risk Factors -- Risks of Implementation
and Financing of Two-Way Services."
 
     Future revenues, costs, product mix and new product acceptance are all
influenced by a number of factors which are inherently uncertain and difficult
to predict. Therefore, no assurance can be given that financing for such
investments will be available. No assurance can be given that the Company's
strategy will be implemented as currently planned or that the Company's
operations will generate positive cash flows.

                                    BUSINESS
 
GENERAL
 
     The Company is one of the fastest growing providers of wireless messaging
services in the United States. Since commencing operations in 1990, the Company
has grown to become the fifth largest paging carrier in the United States, based
on 1,374,146 subscribers at March 31, 1996. The Company's number of subscribers
has increased at annual growth rates of 180%, 136% and 60% in 1993, 1994 and
1995, respectively, as compared to an average annual growth rate of
approximately 31% for 1993 through 1995 for the paging industry. The Company has
made no acquisitions, and all subscriber growth has been internally generated.
The Company has invested heavily in order to achieve rapid growth in its
subscriber base and, as a result, the Company has sustained net losses of $31.1
million, $45.8 million, $53.1 million and $11.6 million for 1993, 1994, 1995 and
the three months ended March 31, 1996, respectively.
 
     The Company offers local, multi-city, regional and nationwide paging and
other one-way wireless services in all 50 states, covering 90% of the population
of the United States. The Company also provides services in Puerto Rico, the
U.S. Virgin Islands and the Bahamas, and has recently initiated nationwide
services in Canada. The Company employs a digital, state of the art transmission
network that is 100% FLEX enabled, allowing the use of high speed messaging
technology, thereby providing increased transmission capacity.
 
PAGING AND MESSAGING INDUSTRY
 
     Industry sources indicate that, as of December 31, 1995, there were over 34
million pagers in service in the United States, which represents a penetration
rate in excess of 13% of the population. The number of pagers in service in the
United States has grown at an annual rate of approximately 28% since 1989.
Factors that have driven subscriber growth include: (i) a continuing shift
toward a service-based economy; (ii) increasing awareness of the benefits of
mobile communication among the population at large, (iii) decreasing equipment
and service prices contrasting with higher priced wireless communication
services such as cellular telephone; (iv) significant productivity, reliability
and coverage area improvements in paging services; (v) improved paging product
functionality; and (vi) expansion of distribution into the mass consumer markets
(e.g. national retail chains and direct sales).
 
     INDUSTRY BACKGROUND/TRADITIONAL SERVICES. Historically, the industry has
been highly fragmented, characterized by a large number of small, local
operators. During the 1990s, however, consolidation increased significantly as
some paging companies grew rapidly, either internally or by acquisition. As a
result, industry sources have reported that over 45% of the estimated number of
pagers in service in the United States are now provided by the five largest
companies by subscriber level.
 
     Over the past decade, traditional paging services have evolved rapidly from
tone-only, digital pagers to sophisticated alphanumeric devices that store
messages with up to 240 characters. Paralleling this product evolution and
concurrent with the reduction in related service and product costs, the market
for paging services has grown from a base of largely specialized users, such as
doctors and business people having time sensitive communication needs, to the
mass consumer market.
 
     Although the paging and messaging industry continues to be characterized by
technological advances, certain basic characteristics are common to most one-way
wireless messaging services. Paging is a one-way wireless messaging technology
that uses an assigned frequency to contact a paging customer within a geographic
service area. Each customer who subscribes to a paging service is assigned a
specific telephone number (or a personal information number). The subscriber is
contacted through this telephone number (or a personal information number) when
the caller is connected, through the public-switched telephone network, with the
paging service.
 
     INDUSTRY EVOLUTION/NEW SERVICES. While paging has been historically a
one-way communications service, technology advances are now providing a two-way
capability for wireless messaging. In 1994, the FCC enhanced the potential for
two-way messaging by allocating and auctioning new frequencies for two-way
paging services. By the end of 1994, the FCC had successfully auctioned
frequencies for both nationwide and
 
                                       32
<PAGE>   33
 
regional two-way services. With the advent of two-way NPCS technology, the
opportunity exists for the development of two-way messaging products and
services that will include inexpensive stored voice and data acknowledgment
paging services that complement the cellular and broadband PCS service
offerings.
 
     The newly-auctioned NPCS spectrum is expected to allow greater
functionality than traditional paging spectrum because it has broader bandwidth
and offers "inbound" and "outbound" spectrum, allowing efficient two-way
communication. With two-way transmission capability, a subscriber unit will be
able to indicate its location to the network. As a result, the message can be
broadcast from the closest transmission site, rather than from all transmission
sites in the entire national, regional or local network, as is the case with
existing paging systems. This should enable more efficient use of the spectrum
in a given geographic area and should greatly increase overall system capacity.
 
     Advanced messaging services may be delivered through several kinds of
subscriber equipment and technology such as Motorola's stored voice messaging
product (which will allow delivery and storage of voice messages to a
pocket-sized pager-like device), enhanced alphanumeric subscriber units, PC
plug-in cards for laptop computers, palmtop computers and Personal Digital
Assistants ("PDAs"), allowing these devices to receive and acknowledge data
messages. Eventually these capabilities may be "built in" obviating the need to
purchase add-on devices such as PC cards. In addition, it is expected that the
enhanced functionality of two-way messaging will attract new subscribers through
value-added services such as voice messaging, wireless origination and delivery
of e-mail, integration of wireless devices into corporate wide area and local
area networks, database access and transaction services.
 
     INDUSTRY OUTLOOK. Future technology developments in the wireless messaging
industry are expected to evolve and drive subscriber growth as users demand more
sophisticated services and devices. The penetration into the mass markets will
continue as retail distribution expands and as non-paging telecommunication
service providers seek to private-label pagers and bundle these services with
their own product offerings. Major telecommunication providers such as AT&T
Wireless, Sprint Corporation and MCI Communications Corporation have all
recently entered into paging service agreements with major messaging service
providers, and this trend is expected to continue.
 
     The wireless industry in general and wireless messaging in particular are
expected to experience robust subscriber growth into the next decade. The
Company believes that its distinct business model positions it well to benefit
from the growth opportunities prevailing in the wireless messaging market today.
Specifically, the Company believes that the combination of its common frequency
nationwide network, centralized administration, diversified distribution
channels and strong spectrum position represents a competitive advantage that
will enable the Company to benefit from the ongoing industry developments.
 
OPERATING STRATEGY
 
     The Company attributes the significant growth of its paging business to the
successful implementation of its six operating principles: (i) diversified
distribution channels, (ii) nationwide common frequency, (iii) efficient network
architecture, (iv) spectrum-rich frequency position, (v) centralized
administration, and (vi) customer service capabilities.
 
          DIVERSIFIED DISTRIBUTION CHANNELS. The Company utilizes a number of
     distribution channels to market its products and services, including retail
     marketing, private brand strategic alliances and national sales offices.
 
             Retail Marketing. The Company believes that it is a leading
        supplier of paging units to consumers through retail distribution
        channels. The Company has been selected as the pager supplier for a
        number of leading retail chains, including Office Depot Inc., Comp USA,
        Inc., Montgomery Ward Company, Inc., Target Stores, Inc. and Best Buy,
        Inc.
 
             Private Brand Strategic Alliances. The Company was one of the first
        paging companies to broaden its distribution reach by establishing
        strategic relationships with large communications providers. The Company
        has established strategic relationships with GTE Corporation, Southwest-
 
                                       33
<PAGE>   34
 
        ern Bell Mobile Systems, AT&T Wireless Services, Ameritech Mobile
        Services, Inc. and long distance reseller EXCEL Telecommunications, Inc.
 
             National Sales Offices. The Company's national sales offices sell
        equipment and services through three distribution channels: direct
        sales, third-party resellers and local retailers. The Company has a
        direct sales force presence in over 75 MSAs through 65 offices.
 
          Management believes that a diversified approach to distribution is
     important to sustain growth as paging services more deeply penetrate the
     United States population, especially the consumer market. This
     diversification is a key element of the Company's strategy of expanding its
     subscriber base as rapidly as possible to increase cash flow through
     greater utilization of its nationwide wireless communication network. A
     diversified distribution strategy also provides a cost effective method for
     managing disconnection rates. The Company's average monthly disconnection
     rates for the twelve months ended December 31, 1994, December 31, 1995 and
     March 31, 1996 were 3.4%, 2.5% and 2.4% per month, respectively.
 
          NATIONWIDE COMMON FREQUENCY. The Company has constructed its
     nationwide messaging network on a common frequency. Use of a common
     frequency provides the Company with a number of important strategic
     advantages not available to many of its competitors which operate on
     multiple frequencies across markets. The use of a common frequency enables
     the Company's customers to travel throughout the United States, Canada and
     the Bahamas while continuing to use the same messaging device. As a result,
     the Company is able to provide multi-city coverage customized to
     accommodate the customer's needs ("coverage on demand"). The common
     frequency also provides a competitive advantage to the Company when
     marketing its services to regional and national retailers and private brand
     strategic alliance partners. These distributors are able to buy the paging
     unit without being limited by where they can distribute the product or by
     the service they sell with the unit. This allows retailers and strategic
     partners to offer customers all service options while minimizing the number
     of SKUs that the distributor must carry, thus reducing inventory carrying
     costs.
 
          EFFICIENT NETWORK ARCHITECTURE. The Company is an industry leader in
     the implementation of advanced telecommunications technologies, including
     pioneering the use of direct broadcast satellite technology for paging. The
     Company's nationwide wireless transmission network is 100% controlled by
     DBS technology, which gives the Company a flexible, highly reliable and
     efficient network architecture. The use of DBS technology eliminates the
     need for expensive terrestrial Rf control links and repeater equipment
     while enabling the Company to provide a wide range of coverage options. The
     Company's network covers the top 300 MSAs across the United States, or
     approximately 90% of the total population in the United States and is
     designed to serve a significantly larger subscriber base than the one
     currently served by the Company. The Company's wireless transmission
     network is 100% FLEX enabled, allowing the use of the high speed FLEX
     protocol to transmit messages and maximize system capacity.
 
          SPECTRUM-RICH FREQUENCY POSITION. The Company ranks among the top four
     paging carriers in the United States in licensed nationwide frequencies.
     The Company's exclusive frequency licenses include two nationwide paging
     frequencies and 150 kHz of nationwide NPCS frequency. The Company believes
     that this frequency has important strategic value because it may enable the
     Company to grow significantly its one-way subscriber base and to provide
     two-way messaging and other value-added services to its subscribers. As a
     result, the Company believes its spectrum-rich frequency position enables
     it to attract private brand strategic alliance partners.
 
          CENTRALIZED ADMINISTRATION. The Company has centralized customer
     service, information systems, inventory control and distribution, credit
     and collections, accounting and marketing functions. This centralized
     administration has enabled the Company to become one of the lowest cost
     providers of paging and other one-way wireless communications services in
     the United States. In addition, the administrative infrastructure is
     designed to support a significantly larger customer base than that
     currently served by the Company, which will allow it to realize additional
     operating efficiency as the Company continues to grow.
 
          CUSTOMER SERVICE CAPABILITIES. Management has focused on developing
     industry-leading customer service capabilities. The Company employs over
     575 highly trained customer service personnel operating
 
                                       34
<PAGE>   35
 
     in state of the art call center facilities. Management believes that these
     services are an important factor in supporting and retaining its strategic
     partners, retailers and subscribers.
 
TWO-WAY MESSAGING STRATEGY
 
     One of the Company's principal strategies is to become a leading provider
of two-way messaging services in the United States. Management believes that the
introduction of two-way messaging services may present significant future growth
opportunities to the Company by enabling it to provide a new generation of
advanced messaging services, including data messaging, stored voice messaging
and other services, to new and existing subscribers.
 
     The Company's two-way messaging strategy is founded on four principal
competitive advantages: (i) nationwide spectrum, (ii) incremental introduction
of technology, (iii) established diversified distribution channels, and (iv)
operating efficiency.
 
     NATIONWIDE SPECTRUM. With the acquisition of the NPCS Licenses, the Company
became one of four companies with 150 kHz or more of nationwide NPCS frequency.
As a result, the Company is positioned to create a high capacity nationwide
network capable of delivering local, multi-city, regional, or nationwide data
and stored voice messaging services to a large number of subscribers.
 
     INCREMENTAL INTRODUCTION OF TECHNOLOGY. The Company intends to introduce
two-way messaging technology by initially building upon its one-way transmission
network, enabling the Company to minimize the level of capital expenditures and
investments. The Company plans to introduce two-way stored voice service paced
to the availability of infrastructure equipment, subscriber devices and to meet
the market demand for such services.
 
     ESTABLISHED DIVERSIFIED DISTRIBUTION CHANNELS. The Company plans to
leverage its established diversified distribution channels to achieve efficient,
rapid market penetration of its two-way services.
 
     OPERATING EFFICIENCY. The Company expects to utilize its existing one-way
network and centralized administration to minimize incremental costs of product
and service expansion. Management believes that the Company's centralized
customer service, information systems, inventory control and distribution,
credit and collections, accounting and marketing organizations will be capable
of supporting the Company's two-way strategy.
 
     As a result of these operating advantages, the Company plans to provide a
complete array of two-way services at affordable prices, including stored voice
and data services, that the Company believes should appeal to a large number of
potential subscribers.
 
     The Company expects to begin testing two-way data and stored voice services
in the second quarter of 1996. Upon completion of testing, two-way data services
are expected to be marketed on a city-by-city basis beginning in late 1996.
Two-way data services may include guaranteed alphanumeric message delivery with
acknowledgment and message with response capabilities. In 1997, the Company
plans to introduce its VoiceMart service which should provide subscribers with
the ability to receive stored voice messages directly to their messaging
devices. Introduction of the VoiceMart service will be paced to the availability
of infrastructure equipment, subscriber devices and market demand.
 
COAM STRATEGY
 
     The Company's operating model is unique in the industry in that it follows
a strategy of selling rather than leasing messaging equipment to subscribers.
The selling expenses of the Company, which include advertising, compensation
paid to its sales force and the loss on pagers sold, associated with the
Company's COAM strategy, are substantial for each messaging unit. As of March
31, 1996, approximately 99% of the Company's messaging units were COAM, which
compares to an industry average of approximately 56%. The Company believes that
by following a COAM strategy it can achieve significantly better capital
efficiency than if it were to follow a lease strategy, which is reflected in its
relatively low capital employed per subscriber of $41 at March 31, 1996. Capital
employed per subscriber represents total assets, less NPCS Licenses, cash,
 
                                       35
<PAGE>   36
 
non-debt current liabilities and international investments divided by units in
service. The Company believes that its COAM strategy provides additional
benefits, including reduced risk of technological obsolescence and avoidance of
the credit risk associated with leasing pagers to end-users. In addition,
management believes that this strategy minimizes its disconnection rates in the
retail channel. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
SALES AND MARKETING
 
     The Company's customers include individuals, corporations and other
organizations that desire affordable communication services offering substantial
mobility, accessibility and the ability to receive timely information. The
Company utilizes a number of distribution channels to market its products and
services, including retail marketing, private brand strategic alliances and
national sales offices. Management believes that a diversified approach to
distribution is important to sustain growth as demand for paging services more
deeply penetrates the United States population, especially the consumer market.
This diversification is a key element of the Company's strategy of expanding its
subscriber base as rapidly as possible to increase cash flow through greater
utilization of its nationwide wireless communication network. The Company is not
dependent on any single customer or a few customers, the loss of one or more of
whom would have a material adverse effect on the Company.
 
     RETAIL MARKETING
 
     Since early 1993, the Company has been an industry pioneer in developing
the retail distribution channel through sales arrangements with regional and
national retail chains that sell electronic and business equipment or consumer
goods. The Company provides equipment to a retailer who then sells the equipment
to potential users. Once the unit is purchased, the customer can activate it and
subscribe for local, regional or nationwide paging coverage with the Company by
simply calling the toll-free number identified on the unit. Because the
Company's pagers operate on a common nationwide frequency, they can be sold in
any retail store located in the Company's nationwide coverage area. By contrast,
competitors that use multiple frequencies across markets require retailers to
maintain many more SKUs to serve each local market that utilizes a different
frequency.
 
     The Company has entered into sales arrangements with a number of large
retail chains such as Office Depot, Inc., Comp USA, Inc., Montgomery Ward
Company, Inc., Target Stores, Inc. and Best Buy, Inc. Retail distribution also
allows the Company to sell pagers in markets that would not support a direct
sales office but in which it has installed the necessary equipment required for
providing paging services. The Company can thus enter new markets by
capitalizing on its existing infrastructure of transmitters with the only
incremental expense being the procurement of local access phone lines. The
Company expects retail sales to become an increasingly important channel of
distribution for pagers. The number of national retail store locations has
increased to 3,690 stores at March 31, 1996, from 3,411 stores, 2,200 stores and
840 stores at December 31, 1995, 1994 and 1993, respectively. Approximately 25%
of the Company's sales are made through the retail channel.
 
     PRIVATE BRAND STRATEGIC ALLIANCES
 
     The Company has established numerous strategic relationships with large
communications providers. These companies utilize their brand awareness and
billing efficiencies to market private brand pagers and services using the
Company's transmission network. Approximately 10% of the Company's sales are
made through private brand strategic alliances, and the Company expects this
proportion to increase over the next several years.
 
     GTE CORPORATION. During 1993 and 1994, the Company and GTE signed a series
of agreements providing for the sale and marketing through GTE of GTE-labeled
services throughout the United States. In addition, several of these agreements
provide for joint cooperation in the deployment of paging network facilities for
the provision of wireless messaging and data transmission in the United States.
Pursuant to the terms of one of the agreements, GTE will purchase up to 250 new
transmitters to be deployed throughout the Company's
 
                                       36
<PAGE>   37
 
nationwide network. The Company will lease, operate and maintain the
transmitters and will provide wireless services to GTE customers, as well as
customers of the Company via the Company's nationwide network. The Company's
services are sold across the United States through GTE Telephone Operations, GTE
Phone Mart Stores and GTE Mobilnet.
 
     SOUTHWESTERN BELL MOBILE SYSTEMS. In May 1995, the Company and SBMS signed
an agreement for the sale and marketing through SBMS of SBMS-labeled services.
After a successful test in several Texas markets in the third quarter of 1995,
SBMS has expanded marketing of the service into its other major markets
including Chicago, Kansas City, St. Louis, Boston and Washington, D.C.
 
     AT&T WIRELESS SERVICES. In November 1995, the Company and AT&T Wireless
entered into a three-year agreement for the sale and marketing through AT&T
Wireless of AT&T Wireless-labeled services. In March 1996, AT&T Business
Communications commenced controlled introduction of its Personal Reach Service,
which utilizes the Company's network.
 
     AMERITECH MOBILE SERVICES, INC. In February 1996, the Company and Ameritech
signed an agreement for the sale and marketing through Ameritech of
Ameritech-labeled services.
 
     EXCEL TELECOMMUNICATIONS, INC. In March 1996, the Company and Excel, a long
distance reseller, signed an agreement for the sale and marketing through Excel
of Excel-labeled services.
 
     NATIONAL SALES OFFICES
 
     The Company's national sales offices sell equipment and services through
three distribution channels: direct sales, third-party resellers and local
retailers. The Company has a direct sales force of 445 personnel located in over
75 MSAs through 65 offices.
 
     DIRECT SALES. The Company markets its equipment through its direct sales
force and related marketing activities such as telemarketing and advertisements
in radio, print media and telephone company yellow pages. Direct sales
representatives are paid by commission (which varies depending on the type of
service subscribed for and other factors) for each unit sold or placed in
service. Approximately 30% of the Company's sales are generated through its
direct sales force.
 
     THIRD-PARTY RESELLERS. In addition to offering paging and messaging
services directly to end-users, the Company also provides services under
marketing agreements with third-party resellers. Typically, the Company offers
third-party resellers paging services in bulk quantities at a wholesale monthly
rate that is lower than the Company's regular retail rates. Approximately 35% of
the Company's sales are made through third-party resellers.
 
     LOCAL RETAILERS. The Company markets its services under sales arrangements
with local retailers located in the MSAs where national sales offices are
present.

MESSAGING SERVICES
 
  Paging Services
 
     The Company charges subscribers a monthly fee which covers the paging and
messaging services subscribed for and any additional services purchased by the
subscriber. The amount of the monthly fee varies primarily based on the type of
service provided and the geographic area covered. The Company charges higher
rates for multi-city and nationwide service options.
 
     The Company currently offers the following three basic types of one-way
paging and messaging services.
 
<TABLE>
<CAPTION>
           SERVICE                                        FUNCTIONS
- ------------------------------  -------------------------------------------------------------
<S>                             <C>
Numeric paging................  Provides the subscriber with the telephone number of the
                                person who is seeking to contact the subscriber. Numeric
                                pagers can store and retrieve up to 40 numeric messages,
                                which are displayed on a liquid crystal display.
Alphanumeric paging...........  Offers the subscriber the ability to receive a text message
                                rather than simply a numeric message. Alphanumeric pagers can
                                store and retrieve up to 40 messages of up to 80 characters
                                each, which are displayed on a liquid crystal display.
Wireless messaging............  Offers subscribers the ability to receive detailed text
                                messages and information services through "message ready"
                                electronic organizers and PCMCIA cards. Wireless messaging
                                devices are capable of receiving messages of several thousand
                                characters in length.
</TABLE>
 
     NUMERIC PAGING. Among the Company's subscribers who use a numeric display
pager, a high percentage select local coverage, although the percentage of
subscribers who select multi-city coverage has been increasing. Monthly fees for
regional and national paging coverage are substantially higher than the fees
charged for single local area coverage. The Company's revenues from multi-city
coverage increased to approximately 29% of airtime revenues for the month ended
March 31, 1996 from approximately 28% during the month ended December 31, 1995.
 
     ALPHANUMERIC PAGING. The Company launched its alphanumeric paging services
in July 1993 under the tradenames InfoPage(R) and InfoNow(SM), and the number of
subscribers utilizing this service represented approximately 1.6% of the
Company's total subscribers as of March 31, 1996. The percentage of paging
industry subscribers utilizing alphanumeric pagers at the end of 1995 was
reported to be approximately 9%. The Company has not focused a significant
portion of its selling and marketing efforts on alphanumeric paging service,
primarily because technology has inhibited the Company's ability to deliver the
service in a cost effective manner. With the Company's introduction of high
speed FLEX protocols, the Company anticipates alphanumeric paging service
becoming a larger portion of its selling and marketing efforts. The ability of
alphanumeric pagers to deliver longer text messages, including the ability to
store messages received for playback when desired by the subscriber, allows the
Company to charge significantly higher monthly fees for its InfoPage and InfoNow
services than for numeric display paging services.
 
     WIRELESS MESSAGING. The Company began offering one-way wireless messaging
services to subscribers with electronic organizers at the end of the first
quarter of 1994. The Company has developed strategic relationships with computer
manufacturers that are integrating advanced wireless messaging capabilities into
their applications software and a new generation of personal digital assistants
and portable computers. Handheld computers featuring PCMCIA slots can
accommodate PCMCIA pager cards to provide office professionals with "message
ready" devices that allow them to be in touch while away from their offices. The
Company's wireless services to PCMCIA pager cards is being marketed under the
service mark InfoAdvantage(SM).
 
     The Company has established the following strategic relationships for the
marketing and provision of wireless data transmission. The market for the
one-way delivery of extended length messages is small in comparison to
traditional numeric and alphanumeric services, and the Company has not realized
significant
 
                                       38
<PAGE>   39
 
revenues from these relationships to date. However, management believes these
relationships will be valuable for distribution of its two-way messaging
services.
 
          International Business Machines, Inc. ("IBM"). In December 1993, IBM
     selected PageMart to be a ThinkPad Proven Vendor to provide one-way
     wireless messaging services to IBM portable computer customers. PageMart
     markets its wireless services to existing owners of ThinkPads through a
     direct mail program and to new owners through a pre-installed computer
     slide show that IBM includes on selected new ThinkPad models.
 
          Mitsui Comtek Corporation ("Mitsui"). The Company has worked with
     Mitsui in the design of the industry's first electronic organizer with a
     built in wireless messaging receiver and now provides one-way messaging
     services for electronic organizers manufactured by Casio Computer Company
     Limited.
 
          CompuServe, Inc. ("CompuServe"). In May 1995, the Company was one of
     several paging carriers selected by CompuServe for the wireless delivery of
     electronic mail (or notice thereof) to CompuServe subscribers.
 
     ADDITIONAL VALUE-ADDED SERVICES
 
     In addition to paging services, the Company offers subscribers a number of
additional value-added services, including voicemail services that allow
subscribers to retrieve voice messages from persons attempting to contact the
subscriber. In addition, the Company offers a numeric message retrieval service
which allows a subscriber to retrieve messages that were sent at a time when the
subscriber was outside of his or her service area. Other optional services
include a nationwide toll-free 800 access number for paging subscribers, a
customized voice prompt that allows subscribers to record a personal greeting,
maintenance agreements and loss protection programs. Approximately 22% of the
Company's recurring revenues during the fiscal quarter ended March 31, 1996 were
derived from these additional services.
 
     The Company also plans to offer wireless connectivity to the Internet for
message transfer and information requests through the "PageMart Wireless Web"
service utilizing the Company's wireless communications network. These services
will include electronic mail, news and other information delivered to messaging
devices, as well as guaranteed message delivery with acknowledgment using the
Company's wireless network for transmission and response.
 
     TWO-WAY SERVICES
 
     One of the Company's principal strategies is to become a leading provider
of two-way messaging services in the United States. Management believes that the
introduction of two-way messaging services may present significant future growth
opportunities to the Company by enabling it to provide a new generation of
advanced messaging services, including data messaging, stored voice messaging
and other services, to new and existing subscribers.
 
     The Company expects to begin testing two-way data and stored voice services
in the second quarter of 1996. Upon completion of testing, two-way data services
are expected to be marketed on a city-by-city basis beginning in late 1996.
Two-way data services may include guaranteed alphanumeric message delivery with
acknowledgment and message with response capabilities. In 1997, the Company
plans to introduce its VoiceMart service, which should provide subscribers with
the ability to receive stored voice messages directly to their messaging
devices. Introduction of the VoiceMart service will be paced to the availability
of, infrastructure equipment subscriber devices and market demand.
 
     The Company's planned service offerings are expected to be delivered to a
pocket-sized subscriber unit containing a transmitter, enabling it to send a
signal identifying its location to the Company's network. Management estimates
that the Company's enhanced alphanumeric services and stored voice messaging
 
                                       39
<PAGE>   40
 
services will be offered to customers at monthly prices competitive with current
one-way alphanumeric paging services in similar service areas. The Company's
service offerings are expected to include:
 
          Enhanced Alphanumeric Messaging. The Company's enhanced alphanumeric
     messaging service will enable the subscriber to receive alphanumeric
     messages up to several thousand characters in length (compared to the
     approximately 80 characters in traditional one-way alphanumeric messaging)
     which will be input by either (i) a computer or other software-enabled
     device with the proper software and a modem that can access the Company's
     network or (ii) a dispatch operator. The service is expected to be based on
     Motorola's state of the art ReFLEX25(TM) technology. This technology will
     permit the network to locate the subscriber before sending the message and
     verify that the subscriber unit has obtained the message ("guaranteed
     delivery").
 
          The Company believes that penetration of alphanumeric service on a
     regional and nationwide basis has been limited to date due to the
     reluctance of many one-way paging operators to promote the service because
     of its relatively high use of system capacity during transmission. The NPCS
     Licenses and the ReFLEX25 and InFLEXion(TM) technologies should offer
     significant increases in capacity and delivery speed over the spectrum and
     technology currently delivering alphanumeric messaging services. The
     Company expects that its enhanced alphanumeric service will improve upon
     traditional service by permitting longer messages, by guaranteeing and
     acknowledging delivery and, eventually, by permitting the subscriber to
     initiate limited data responses. Management believes that these service
     enhancements, along with its competitive pricing, will appeal to
     subscribers of traditional alphanumeric messaging services and to cost
     conscious customers who have not previously subscribed to such services.
 
          VoiceMart Service. The Company's VoiceMart service will be an entirely
     new generation of messaging service. The service may utilize Motorola's
     state of the art InFLEXion compressed stored voice technology to deliver a
     high quality transmission of the sender's voice to the wireless stored
     voice messaging product. The unit will store up to four minutes of voice
     messages, which the subscriber will be able to play, fast-forward, rewind
     and delete, much like an answering machine or voice mailbox. If the
     subscriber unit is full, the sender's message will be stored in a network
     server. The network will then transmit a "message waiting" notification to
     the subscriber unit. The subscriber can delete old messages to enable the
     unit to immediately receive messages stored by the network. While the
     subscriber will not be able to respond directly to the caller by speaking
     into the unit, the subscriber unit will acknowledge receipt of the voice
     message to the network. The subscriber unit will have a volume control to
     allow the subscriber to listen to messages privately, or to play them aloud
     for others to hear.
 
          Other Services. Over time, the Company intends to participate in the
     growth of wireless data messaging services through new and existing
     strategic alliances, wireless data alliances with software companies and
     electronic equipment manufacturers to develop additional data messaging
     services. In addition to pocket-sized pagers, the Company expects that
     wireless data transmissions will be received by computers, organizers or
     PDAs equipped with two-way Rf modems or built-in Rf capability. It is
     anticipated that a limited response by the device will be possible.
 
     PACT(TM) SERVICES. The Company anticipates that its two-way messaging
network will also be capable of broadcasting the pACT protocol, a high speed
NPCS protocol developed by AT&T. However, the Company has not yet received a
commitment from its suppliers to provide such capability and there can be no
assurance that such capability will be made available to the Company. Messaging
services provided on the pACT protocol are expected to be very similar to
enhanced alphanumeric messaging, voice messaging services and other services
described above.
 
ONE-WAY TRANSMISSION NETWORK
 
     The Company utilizes DBS technology exclusively in its one-way transmission
network. Although the Company's one-way transmission network is substantially
built out, the Company continues to make expenditures to improve and expand its
coverage into new areas. The Company's use of the DBS system has certain cost
and performance advantages over traditional paging systems and traditional
satellite paging systems.
 
                                       40
<PAGE>   41
 
     Traditional Paging Systems. The traditional method of controlling paging
transmitters in local and regional simulcasting systems is to use terrestrial Rf
control links that originate from one broadcast transmitter that is controlled
by a local paging terminal. At the paging terminal, the messages are received
and assembled for transmission via Rf or wireline control link to each
transmitter. Once a message is received by each transmitter in a simulcast
market, it in turn broadcasts the paging information using the paging broadcast
frequency. The Rf control link frequency is different from the paging broadcast
frequency.
 
     In order to simulcast the paging signal, a traditional system must be
fine-tuned (optimized) so that each transmitter broadcasts the paging signal at
the same time. Optimization becomes more complex and expensive as the service
area expands. In addition, since a traditional system requires line-of-site
transmission of the Rf control link signal, repeater stations must be used to
re-broadcast this Rf signal in a large system such as the New York or Los
Angeles metropolitan areas. The more distant the transmitter sites are from the
central Rf control link transmitter, the more repeaters are necessary. Repeater
stations make optimization more difficult and increase equipment and recurring
tower rental costs. For non-contiguous regional coverage either telephone lines
or microwave communication links are typically used in lieu of Rf control links.
 
     Traditional Satellite Paging Systems. Some paging system operators have
adopted an alternative approach using satellites, rather than telephone lines,
to communicate between the paging terminal and the traditional Rf control link
systems. Numeric and alphanumeric messages are processed by a central paging
terminal that uplinks the messages to a satellite, which then broadcasts the
messages to the destination cities. The satellite signal is received by one
central Rf radio control transmitter paging dish in each city and broadcast via
traditional Rf control link transmitters to the paging transmitters in that
city.
 
     With this infrastructure, the satellite is used only in place of other long
distance communication options. Both an Rf control link frequency and a paging
signal frequency must be employed as with a traditional system. The current
broadcast configuration employed by many other leading nationwide carriers has
the added inefficiency of satellite transmissions that address their entire
nationwide system or entire regions whenever a page transmission is sent, thus
limiting the total number of subscribers on the system.
 
     The Company's Direct Broadcast Satellite Paging System. The Company has
developed an innovative satellite-based transmission network that gives the
Company a flexible, highly reliable network architecture and an efficient
operating structure. The Company's network is comprised of three primary
components: network access, a nationwide network linking the Company's paging
terminals and a satellite network which controls the Company's transmitters.
 
     The Company's numeric and alphanumeric paging services can be accessed via
local telephone numbers or 800 numbers using a touch-tone key pad or personal
computer messaging software. Local numbers are provided by regional telephone
companies and 800 number service is provided by long distance telecommunications
services providers. The Company uses a nationwide data network to carry all
paging traffic from local telephone markets to its satellite uplink facilities
in Illinois. This network configuration allows the Company to add new lines
quickly and efficiently and provides the Company with back-up power, fire
protection and diverse routing capabilities.
 
     The Company began using DBS technology in 1990 and was the first one-way
wireless communications carrier to use DBS technology to control all of its
transmitters. Currently, the Company is one of only three carriers that employ
DBS technology in a nationwide paging system. With a DBS paging system, the
satellite can broadcast messages directly to each transmitter in the Company's
paging system, which then broadcasts the message to pagers on the Company's
nationwide broadcast frequency. DBS eliminates the expensive terrestrial radio
link and repeater equipment that many paging companies have employed to control
simulcast transmissions in large metropolitan markets. In addition, the
Company's satellite system can selectively address one or any combination of its
transmitters, thereby providing a wide range of coverage options and permitting
efficient use of paging frequencies in each market. The Company leases its
satellite services pursuant to the Satellite Service and Space Segment Lease
Agreement, dated January 2, 1995, with SpaceCom Systems, Inc. ("SpaceCom"). The
agreement subjects the Company to monthly service charges based on the amount
and types of services used and expires on January 31, 2002. The agreement may be
terminated by SpaceCom upon certain failures of the Company to pay monthly
service fees. The agreement
 
                                       41
<PAGE>   42
 
does not include any renewal provisions. Although the Company is currently party
to only one satellite service agreement, management believes that the services
provided by SpaceCom are sufficient to meet the Company's foreseeable needs and
that there are numerous alternate satellite sources available to the Company on
comparable terms and conditions. As a result, the Company does not believe the
loss of its relationship with its current satellite supplier would have a
material adverse effect on its business and operations.
 
     The Company does not manufacture any of the pagers used in its paging
operations. Currently, the Company buys approximately 60% of its pagers from
Motorola with the remainder purchased from other manufacturers. The Company is
dependent on such manufacturers to obtain sufficient pager inventory for new
subscriber units and replacement needs. See "Risk Factors -- Dependence on Key
Suppliers."
 
     BENEFITS OF THE DIRECT BROADCAST SATELLITE. The use of a DBS broadcast
system provides a number of benefits to the Company including:
 
     - Selectively addresses one or all markets to provide a wide range of
       local, multi-city, regional or nationwide coverage options. The Company's
       system configuration employs a high degree of spectrum efficiency with
       regard to the paging frequency because only the coverage area the
       customer has elected will be activated with each page.
 
     - Replaces terrestrial Rf control link equipment with satellite based
       equipment and signaling. This eliminates capital expenditures associated
       with terrestrial RF control link equipment and the associated
       telecommunications expenses, utilities and ongoing site rent and requires
       much lower expenditures for satellite receivers and satellite service.
 
     - Suffers significantly less degradation in performance due to building
       reflection and simulcasting problems, such as the overlapping of two
       independently controlled markets.
 
     - Allows for rapid deployment of the network system because the
       transmitters are operational immediately upon installation, while
       terrestrial Rf control links need to be optimized, which can take up to
       three months in some large urban markets.
 
     - Supports the high data rates that will be required in order to
       effectively provide enhanced services such as two-way messaging services.
       Management believes that this will allow the Company to implement higher
       speed signal technologies quickly and in a cost effective manner.
 
TWO-WAY MESSAGING
 
NARROWBAND PCS PROTOCOLS
 
     Paging networks use various "protocols" to provide seamless communications
between the various components which make up a paging network. Protocols
regulate the format and flow of messages which are transmitted over the network.
As such, protocols facilitate the orderly and efficient flow of message traffic
over the network. Motorola has developed, and licensed to Glenayre, several
protocols, including FLEX, ReFLEX25, ReFLEX50(TM) and InFLEXion. Of these four
protocols, the Company believes that ReFLEX25, ReFLEX50 and InFLEXion permit
two-way alphanumeric messaging, but only InFLEXion currently has the capability
to offer cost-efficient stored voice messaging, very high-speed data delivery
and the transmission of data to the subscriber unit. The Company also believes
that AT&T has also developed a proprietary protocol "Personal Air Communications
Technology," or pACT, for two-way wireless transmission of data and alphanumeric
messages.
 
                                       42
<PAGE>   43
 
     These various protocols have different transmission speeds and capacity
characteristics. Consequently, the ability to deliver various types of wireless
messaging services, including stored voice messaging, on a cost-efficient basis
is dependent upon the protocol used. The following table illustrates certain
characteristics of various protocols based on current publicly available
information.

TWO-WAY NETWORK BUILDOUT
 
     The Company expects to design and construct its nationwide NPCS network to
provide stored voice and data services and currently expects to complete
substantially its network buildout by the end of 1998. The key elements of the
network buildout are as follows:
 
          Design. The design of the Company's nationwide NPCS network is
     expected to be based upon Motorola's ReFLEX25 and InFLEXion technologies in
     order to achieve efficient use of the Company's spectrum and to accommodate
     a greater number of subscribers. The Company may also incorporate AT&T's
     proprietory messaging protocol pACT into its network. The design process
     requires extensive Rf planning, which involves the selection of specific
     sites for the placement of transmitters and receivers as well as
     functioning infrastructure equipment from manufacturers. As part of the
     design process, the Company's engineers are identifying sites using the
     Company's proprietary database (as well as other sources), which contains
     specific information about available sites throughout the nation. Sites are
     chosen on the basis of their coverage and on frequency propagation
     characteristics, such as terrain, topography, building penetration and
     population density. The Company's engineers currently project that the
     Company's nationwide NPCS network will consist of approximately 2,300
     transmitter/receiver sites and approximately 1,700 stand-alone receivers
     when the network is substantially completed.
 
          Equipment. The infrastructure of the Company's network will consist of
     radio transmitters and receivers, switches, Rf controllers and ancillary
     equipment, such as coaxial cable and antennas. The Company plans to
     purchase this infrastructure equipment (other than the ancillary equipment)
     from industry leading equipment suppliers, Motorola and Glenayre. The
     Company believes that currently there is only a limited number of suppliers
     of terminals and transmitters and as a result the Company is dependent on
     such suppliers for its infrastructure equipment needs. The Company
     currently has no
 
                                       43
<PAGE>   44
 
     agreements that require it to purchase infrastructure equipment or
     messaging units for its two-way services. See "Risk Factors -- Dependence
     on Key Suppliers."
 
          Development of Technology. While the terminals and transmitters will
     be similar to the equipment used in the Company's one-way messaging
     network, the Company believes that Motorola is conducting over-the-air
     testing of its InFLEXion technology, infrastructure equipment and
     subscriber units in its factory in Fort Worth, Texas. While the tests do
     not take into account certain factors prevalent in the design of the
     Company's two-way network buildout such as terrain topography, building
     penetration and population density, the Company believes that Motorola
     expects to establish that the technology and equipment can deliver a
     wireless voice message to subscriber unit under controlled circumstances.
     The Company also believes that Motorola's ReFlex technology has recently
     been introduced and has been used commercially by another paging company.
     However, there can be no assurance that two-way services will be
     commercially viable, and the success of two-way services could be affected
     by matters beyond the Company's control. See "Risk Factors -- Risks of
     Implementation and Financing of Two-Way Services."
 
     The Company expects to purchase a significant portion of its subscriber
messaging units from Motorola, with the remainder expected to be purchased from
other manufacturers. The Company understands that Motorola has licensed to other
wireless equipment manufacturers the relevant signaling system technology, as
Motorola has done with signaling system technology for its other FLEX protocols.
Although the Company believes that sufficient alternative sources of two-way
messaging units will exist, the Company would be adversely affected if it were
unable to obtain the units on satisfactory terms. See "Risk
Factors -- Dependence on Key Suppliers." The Company currently has no agreements
that require it to purchase infrastructure equipment or messaging units for its
two-way services.
 
     As the Company begins development and implementation of two-way services,
the Company expects to incur significant additional operating losses during the
start-up phase for such services, and it will be necessary for the Company to
make substantial investments. The Company anticipates requiring additional
sources of capital to fund the construction of a two-way messaging network,
including expenditures relating to the build-out requirements of the FCC. See
"-- Government Regulation." The Company anticipates investing $75 to $100
million through fiscal 1997 to test and construct a two-way transmission
network. Thereafter, the Company anticipates that its two-way operations may
require up to $100 million of additional investment to substantially complete
the network buildout. The Company expects to require additional financing to
complete the buildout, which may include joint venture arrangements, however
there can be no assurance that sufficient financing will be available to the
Company. See "Risk Factors -- Risks Related to Implementation and Financing of
Two-Way Services" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
INTERNATIONAL EXPANSION
 
     The Company plans to provide messaging services in selected countries on a
seamless international network. Management believes that its technology,
operational structure and distribution strategies can be replicated in foreign
countries to establish nationwide wireless networks. In each country in which
the Company plans to offer paging and messaging services, the Company will seek
to obtain a nationwide frequency common to at least one of the nationwide
frequencies it holds in the United States in order to allow a single messaging
device to be used in multiple countries. The Company expects to pursue
international opportunities through minority interests in joint venture
arrangements whereby the Company would contribute its expertise in designing and
managing messaging services with minimal incremental capital investments.
 
     The Company's international strategy is initially to pursue opportunities
in North America, Latin America, and South America. One of the Company's
affiliates, PageMart Canada, has obtained a nationwide license in Canada based
on a frequency common to one of its frequencies in the United States. PageMart
Canada began providing service in the largest metropolitan areas in Canada to
U.S. subscribers in March 1996 and to Canadian subscribers in April 1996. The
Company also provides paging coverage in the Bahamas.
 
                                       44
<PAGE>   45
 
     In 1994, PageMart Canada purchased the Canadian network facilities of
Motorola EMBARC Canada for approximately $1.7 million and entered into an
agreement with Motorola to sell transmission time to Motorola for five years. In
1995, Toronto Dominion Capital Group Ltd. ("TD Capital") and Working Ventures
Canadian Fund, Inc. ("Working Ventures") purchased a majority interest of Canada
Holding for $5 million. In January 1996, PageMart Canada was awarded one of the
same nationwide frequencies the Company uses in the United States. The Company's
cash investment in Canada Holding and PageMart Canada totals approximately $3.7
million. Through PageMart International, Inc. the Company owns 20% of the voting
common stock of PageMart Canada. Additionally, PageMart International Inc. owns
33% of the voting common stock of Canada Holding which owns the remaining 80% of
the voting common stock of PageMart Canada.
 
     The common frequency allows the Company's affiliates in each country to
provide customized coverage that extends beyond the borders of the serving
country, using the same pager. For example, a subscriber in New York could
choose New York and Toronto coverage.
 
COMPETITION
 
     The Company competes primarily on the basis of the price of its equipment
and wireless services as well as its coverage capability. Its competitors
include both companies which provide paging or other mobile communications
services in local markets in which the Company operates and regional and
nationwide paging service providers. These include both large and small paging
service providers and regional telephone companies, such as Paging Network, Inc.
MobileMedia Corporation Inc., AirTouch Communications, Inc. and Arch
Communications Group, Inc. Certain of these companies have substantially greater
financial, technical and other resources than the Company. In addition, a number
of paging carriers have constructed or are in the process of constructing
nationwide wireless networks that will compete with the Company's services,
including the provision of two-way messaging. Management believes that its low
cost base and service offerings will enable it to continue to compete
effectively in all markets.
 
     A number of competing technologies, including cellular telephone service,
broadband and narrowband personal communications services, specialized mobile
radio, low speed data networks and mobile satellite services, are used in, or
projected to be used for, two-way wireless messaging services. Cellular
telephone technology provides an alternative communications system for customers
who are frequently away from fixed-wire communications systems (i.e., ordinary
telephones). Compared to cellular telephone service, paging service is generally
less expensive, offers longer battery life, provides better in-building
penetration, extends over wider coverage areas, and is more transportable. For
those cellular customers for whom convenience and price are considerations,
paging can compete successfully by complementing their cellular usage.
Management believes that paging will remain one of the lowest-cost forms of
wireless messaging due to the low-cost infrastructure associated with paging
systems, as well as advances in technology that will reduce paging costs.
Broadband personal communications services technologies are currently under
development and will be similar to cellular technology. When offered
commercially, this technology will offer greater capacity for two-way wireless
messaging services and, accordingly, is expected to result in greater
competition.
 
     Technological advances in the telecommunications industry have created, and
are expected to continue to create, new services and products competitive with
the wireless services currently provided by the Company. In addition, certain
companies are developing one-way and two-way wireless messaging services which
may compete with the one-way and two-way wireless messaging services which the
Company expects to provide. There can be no assurance that the Company will not
be adversely affected as new competitive technologies become available and are
implemented in the future. In addition, the Company may be adversely affected if
cellular telephone companies or broadband personal communications service
providers begin to provide other wireless services or enter into partnerships
with other companies to provide wireless services that complement cellular or
broadband PCS services.

GOVERNMENT REGULATION
 
     Wireless messaging operations are subject to regulation by the FCC under
the Communications Act, including recent amendments contained in the
Telecommunications Act of 1996. At the present time, wireless messaging services
are primarily offered over radio frequencies that the FCC has allocated for
either common carriage (the licensees for which are known as RCCs), or private
carriage (the licensees for which are known as PCPs). RCCs are granted an
exclusive license to a particular radio frequency in a particular locality or
region. Certain qualified PCPs have been granted such exclusive use of their
frequencies as well. In addition, the FCC has recently granted, by auction,
regional and nationwide NPCS licenses that can be used for advanced paging
services, such as two-way paging.
 
     The Company provides one-way paging services directly to subscribers over
its own transmission facilities and is currently regulated as a PCP for most of
its services. The Company (through subsidiaries) holds certain RCC licenses (the
"RCC Licenses") and two exclusive nationwide PCP licenses, as well as exclusive
licenses on various PCP frequencies in certain metropolitan areas, including New
York, Los Angeles and Chicago (the "PCP Licenses"). Additionally, the Company
holds a Nationwide Narrowband License and five Regional Narrowband Licenses; the
latter five licenses authorize the Company to operate regional narrowband
systems on the same frequencies throughout the continental United States. The
Nationwide Narrowband License was granted on September 29, 1994, and the
Regional Narrowband Licenses were granted on January 27, 1995. The Nationwide
Narrowband License and the Regional Narrowband Licenses may be utilized in
connection with various two-way NPCS services or to expand the Company's
existing one-way transmission network.
 
     The Budget Act amended the Communications Act by creating a new
consolidated category of communications services called Commercial Mobile Radio
Services ("CMRS") in order to more uniformly regulate mobile wireless service
providers. RCCs, PCPs, and NPCS providers are included in the new CMRS category.
The FCC has promulgated regulations to implement these new statutory
requirements. In general, regulatory changes caused by the creation of the CMRS
category are scheduled to become effective in August 1996. Under the amended
Communications Act, differential regulation of providers of CMRS is permitted
only under limited circumstances. If there is no change in the recently adopted
rules, PCPs, RCCs, NPCS licensees and other CMRS providers will have
substantially similar obligations under the Communications Act beginning in
August 1996. All of these licensees will be prohibited from engaging in any
unreasonable discriminatory practices, will be subject to complaints regarding
any unlawful practices and will be subject to provisions that authorize the FCC
to provide remedial relief to an aggrieved party upon a finding of a violation
of the Communications Act and related consumer protection provisions. It is
expected that further rulemaking proceedings may be commenced by the FCC in its
efforts to reconcile its regulation of RCCs, PCPs, and NPCS licensees.
 
     The Company's PCP, RCC and NPCS Licenses (collectively, the "Licenses")
authorize the Company to use the radio frequencies necessary to conduct its
paging operations. The Licenses prescribe the technical parameters, such as
power output and tower height, under which the Company is authorized to use
those frequencies. The Licenses are for varying terms of up to 10 years, at the
end of which time renewal applications must be submitted to the FCC for
approval. Most of the Company's PCP and RCC Licenses expire between 1996 and
1999. In order to be granted the exclusive use of a frequency, the Company is
required to construct and maintain a specified minimum number of transmission
sites, depending upon the breadth of the exclusivity, each of which is licensed
by the FCC (the "Operating Licenses"). Of the Company's over 1,400 Operating
Licenses, 90 require renewal in 1996 and 318 require renewal in 1997. The
Nationwide Narrowband License will expire on September 29, 2004 unless renewed
by the Company. The Regional Narrowband Licenses will expire on January 27, 2005
unless otherwise renewed. FCC renewals are routinely granted in most cases upon
a demonstration of compliance with FCC regulations and adequate service to the
public. Although the Company is unaware of the existence of any circumstances
which would prevent the grant of any pending or future renewal applications, no
assurance can be given that the Licenses will be renewed by the FCC in the
future. Furthermore, although revocation and involuntary modification of
licenses are extraordinary regulatory measures, the FCC has the authority to
restrict the operation of licensed facilities or to revoke or modify licenses.
No License of the Company has ever been revoked or modified involuntarily.

     The Company has complied with FCC requirements with respect to the buildout
of its existing one-way paging network. There are separate FCC buildout
requirements with respect to the Company's NPCS Licenses. As a nationwide NPCS
licensee, the Company must construct base stations that provide coverage to a
composite area of 750,000 square kilometers or serve 37.5% of the U.S.
population within five years of the initial license grant date and must
construct base stations that provide coverage to a composite area of 1,500,000
square kilometers or serve 75% of the U.S. population within ten years of the
initial license grant date. Additionally, as a regional NPCS licensee, the
Company must construct base stations that provide coverage to a composite area
of 150,000 square kilometers or serve 37.5% of the population of the service
area within five years of its initial license grant date and must construct base
stations that provide coverage to a composite area of 300,000 square kilometers
or serve 75% of its service area population within ten years of the initial
license grant date. Failure to meet the construction requirements will result in
forfeiture of the license and ineligibility to regain it.
 
     The Communications Act requires licensees such as the Company to obtain
prior approval from the FCC for the assignment of any station license or the
transfer of control of any entity holding such licenses. The FCC has approved
each transfer of control for which the Company has sought approval. The
Communications Act also requires prior approval by the FCC of acquisitions of
paging companies. The Company also regularly applies for FCC authority to use
frequencies, modify the technical parameters of existing licenses, expand its
service territory and provide new services. Although there can be no assurance
that any requests for approval or applications filed by the Company will be
approved or acted upon in a timely manner by the FCC, or that the FCC will grant
the relief requested, the Company has no reason to believe any such requests,
applications or relief will not be approved or granted.
 
     The Communications Act limits foreign ownership of entities that hold
certain licenses from the FCC, including licenses of the type held by the
Company. Because of this limitation, except pursuant to FCC discretion, no more
than 25% of the Company's stock may be owned, directly or indirectly, or voted
by non-U.S. citizens or their representatives, a foreign government or its
representatives, or a foreign corporation. Based on currently available
information, the Company estimates that its foreign ownership is approximately
22%. However, this percentage is subject to change at any time upon any transfer
of direct or indirect ownership of the Company's Common Stock. If the Company
obtains knowledge that the foreign ownership of its stock exceeds 25%, it would
be forced to either seek approval from the FCC for the additional foreign
ownership or redeem common stock at their current market value (determined as
set forth in the Company's certificate of incorporation) from foreign
shareholders in an amount sufficient to reduce such ownership to below 25% (as
permitted by the Company's certificate of incorporation).
 
     The Budget Act imposed a structure of regulatory fees which the Company is
required to pay with respect to its Licenses. The FCC increased these fees for
fiscal year 1995. The FCC did not impose any increase in these fees for fiscal
year 1996. The Company believes that these regulatory fees will not have any
material adverse effect on the Company's business.
 
     On February 9, 1996, the FCC released a Notice of Proposed Rule Making
("NPRM"), which proposed a system of competitive bidding ("auctions") to issue
licenses for frequencies for which there are mutually exclusive applications.
Under the FCC proposal, licenses for individual paging channels for which there
are mutually exclusive applications would be auctioned on a geographic basis. In
defining the area within which existing users would be protected from
interference from the auction winners or neighboring licensees (an area known as
an "interference contour"), the FCC proposed a new methodology that in many
instances would reduce the size of the area within existing licensees'
interference contours. This change, however, would not have any impact on
licensees with nationwide exclusivity (such as the Company), because no other
operator has the right to apply for such licensees' exclusive frequencies.
 
     While the rulemaking proceeding is pending, the FCC proposed only to
process applications for which the relevant period for filing competing
applications had expired as of the date of the NPRM and which were not mutually
exclusive with other applications. Under the FCC's proposal, licensees with
nationwide exclusivity on a particular frequency (such as the Company), however,
would be permitted to expand their systems. In April 1996, the FCC issued a
Report and Order modifying the NPRM to, among other things, allow
 
                                       47
<PAGE>   48
 
incumbent licensees to file applications for additional transmission sites that
are within 40 miles of an authorized transmission site that was licensed to the
same applicant on the same channel on or before February 8, 1996 (except that,
pursuant to a June 1996 reconsideration order affecting solely 931 MHz licenses,
an application need only have been filed as of September 30, 1995, regardless of
whether such application was granted prior to February 8, 1996) and which is
operational as of the date the application for the additional transmission site
is filed. It is not clear when the rulemaking proceeding will be completed or
what, if any, new rules the FCC will issue as a result of the rulemaking
proceeding.
 
     In another ongoing rulemaking pertaining to interconnection between local
exchange carriers ("LECs") and CMRS providers, the FCC has proposed that
interconnection rates should be based on a "bill and keep" model (i.e., the LEC
and the CMRS provider charge each other a rate of zero for the termination of
the other's traffic). Under the current arrangement, LECs are required to
compensate CMRS providers for the reasonable costs incurred by such providers in
terminating traffic that originates at LEC facilities, and vice versa. The
Company believes that the FCC's "bill and keep" proposal, if applied to paging
services, would not have any material adverse effect on the Company's business.
 
     Some paging services are subject to state regulation as well as regulation
by the FCC. Prior to the amendment of the Communications Act by the Budget Act,
states were permitted to regulate entry into the RCC paging business. States
were not, however, permitted to regulate the provision of paging services by
PCPs. While the Communications Act prohibits states generally from regulating
the entry of or the rates charged by any CMRS provider, whether RCC or PCP, the
new law will not prohibit a state from regulating the other terms and conditions
of CMRS. Several states petitioned the FCC for authority to continue pre-
existing rate regulation over all CMRS providers. In August 1995, the FCC denied
all of the petitions filed by the states.
 
     From time to time, legislation and regulations which could potentially
affect the Company, either beneficially or adversely, are proposed by federal
and state legislators and regulators. In May 1995, the Texas Legislature created
the Telecommunications InfraStructure Fund (the "TIF") as part of the
Telecommunications Act of 1995 (the "Act"). The TIF was established to collect
$150 million annually from the telecommunications providers in Texas. The TIF is
composed of two separate accounts, a "telecommunications utilities account"
which includes telephone companies and long distance providers, and a
"commercial mobile service providers" ("CMSP") account which includes cellular
providers and paging companies. The accounts are financed by annual assessments
totaling $75 million each on the telecommunications utilities and the CMSPs
doing business in Texas. The fraction that is to be paid by each CMSP is
determined by such provider's portion of the total telecommunications receipts
reported by all CMSPs for the purpose of payment of state sales taxes. The TIF
is to be used for grants and loans for equipment, infrastructure, curricula and
training in education and medicine. The Act was signed into law effective
September 1, 1995.
 
     The Company is not required to contribute to the CMSP account until August
1996, when the Company becomes a commercial mobile radio service provider under
federal communications law. However, the Company joined an ad hoc coalition made
up of the largest paging companies to fight the TIF assessment based on its
unfair and disparate treatment of the CMSPs. The coalition filed a lawsuit in
federal court on November 22, 1995, challenging the TIF on constitutional
grounds. The lawsuit, among other things, requested an injunction prohibiting
the state from collecting the assessment until the Texas Legislature has had an
opportunity to rectify the disparity in treatment of the telecommunications
utilities and the CMSPs. The Texas Legislature does not reconvene until January
1997.
 
     On February 5, 1996, the District Court for the 261st Judicial District,
Travis County, Texas, entered a final judgment declaring that the assessment on
CMSP providers as proposed violated the "equal and uniform taxation" clause of
the Texas Constitution. The court further concluded that CMSPs could be taxed
only on a percentage of taxable telecommunications receipts that does not exceed
the percentage assessed against the telephone utilities. After August 10, 1996,
the Company will be assessed based on the lower rate applicable to
telecommunications utilities. Management is not aware of any other proposed or
pending state legislation imposing a similar assessment or creating a similar
fund.

TRADEMARKS
 
     The Company owns certain intellectual property, including without
limitation, trademark and service mark rights associated with certain federal
and foreign trademark registrations and applications, common law trademark,
trade name and service mark rights, and other legal and equitable rights
connected with the Company's voice and data communication products and services
and, in particular, one-way and two-way paging systems and technologies and
related services. The Company markets its multiple city wireless service under
the name Pick-Your-Cities(R) and its nationwide service under the name
Page-Me-USA(R), both of which are federally registered service marks. The
Company has filed applications with the United States Patent and Trademark
Office as well as certain foreign trademark offices to register approximately 85
additional service and trademarks. The Company also has full use of the name
PageMart, as a mark.
 
EMPLOYEES
 
     At March 31, 1996, the Company had 1,610 full-time employees, approximately
1,314 of whom were engaged in sales and customer service.
 
     No employees of the Company are covered by a collective bargaining
agreement, and management believes the Company's relationship with its employees
is good.
 
PROPERTIES
 
     The principal tangible assets of the Company are its paging network
equipment. Paging network equipment utilized by the Company includes paging
switching terminals, paging transmitters and a host of related equipment such as
satellite and digital link controllers, satellite dishes, antennas, cable, etc.
The Company continues to add equipment as it expands to new service areas. To
date, it has not experienced any difficulty or delay in obtaining equipment as
needed.
 
     The Company acquired the NPCS Licenses in auctions held by the FCC. The
NPCS Licenses permit the nationwide operation of NPCS networks with 100 kHz of
outbound capacity and 50 kHz of response capacity.
 
     The Company generally leases the locations used for its transmission
facilities under operating leases. These leases, which are generally for five
years or less, currently provide for aggregate annual rental charges of
approximately $4.7 million. The Company does not anticipate difficulty in
renewing these leases or finding equally suitable alternate facilities on
acceptable terms. The Company also leases approximately 130,238 square feet of
office space for its corporate headquarters in Dallas, Texas, at an annual cost
of approximately $1.1 million and varying lesser amounts for local offices at
other locations. Aggregate annual rental charges under the Company's local
office leases are approximately $1.8 million.
 
LEGAL PROCEEDINGS
 
     The Company is involved in various lawsuits arising in the normal course of
business. In management's opinion, the ultimate outcome of these lawsuits will
not have a material adverse effect on the results of operations or financial
condition of the Company.
 
     On July 8, 1994, an action against the Company was filed in the United
States District Court for the Eastern District of New York by Universal Contact
Communications Inc., a former reseller of the Company's wireless messaging
devices. The Company terminated the reseller relationship due to a monetary
default by plaintiff. The Company subsequently contacted plaintiff's customers
in an effort to provide continued service directly through the Company, and
discontinued plaintiff's paging services. In the complaint, plaintiff alleges,
among other things, that the Company violated federal law by making unsolicited
advertisements, breached its contract with plaintiff, slandered plaintiff,
converted certain confidential information and trade secrets, tortiously
interfered with plaintiff's business and contractual relations, and engaged in
unfair competition. Plaintiff seeks, among other things, compensatory damages of
$500,000 with respect to each of the nine causes of action included in the
complaint, punitive damages of $5,000,000, and various forms of injunctive
relief. The Company is vigorously defending the action. In management's opinion,
the ultimate outcome of this lawsuit is not expected to have a material adverse
effect on the results of operations or financial condition of the Company.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The compensation committee of the Company consists of Frank V. Sica, Guy L.
de Chazal, and Arthur Patterson. No executive officer of the Company serves as a
member of the compensation committee of the Company, or on the compensation
committee of another corporation, an executive officer of which serves as a
director of the Company or on the Company's compensation committee, and no
executive officer of the Company serves as a director of another corporation, an
executive officer of which serves as a member of the Company's compensation
committee.
 
STOCK OPTION PLAN
 
     The Company's Third Amended and Restated 1991 Stock Option Plan (the "Stock
Option Plan") authorizes the grant of non-qualified options ("NSOs") to purchase
shares of Class A Common Stock to key employees, directors and others deemed to
provide valuable services to the Company as additional compensation and to
encourage them to continue to provide service to the Company. In addition,
options qualifying as incentive stock options ("ISOs") under Section 422 of the
Internal Revenue Code of 1986, as amended, (the "Code") may be granted to
employees of the Company.
 
     The stock issuable under the Stock Option Plan includes shares of the
authorized but unissued or reacquired Class A Common Stock. The number of shares
for which options may be granted under the Stock Option Plan (together with the
number of shares issued under the Stock Issuance Plan described below) may not
exceed 4,550,000 shares. Shares underlying any options that are not exercised
prior to expiration or termination or are canceled are available for subsequent
option grants under the Stock Option Plan.
 
     The option exercise price per share will be fixed by the committee of the
Board responsible for administration of the Stock Option Plan (the "Stock Option
Plan Committee"), but in no event may the option price per share be less than
85%, with respect to options other than ISOs, or 100%, with respect to ISOs, of
the fair market value of a share of Class A Common Stock on the grant date. If
the individual to whom the ISO is granted is at the time the holder of at least
10% of the capital stock of the Company (a "Significant Stockholder"), then the
option price per share may not be less than 110% of the fair market value of the
Class A Common Stock on the grant date. Options are exercisable over such period
as may be determined by the Stock Option Plan Committee, but no option may
remain exercisable more than ten years from the grant date, and no ISO granted
to a Significant Stockholder may remain exercisable more than five years from
the grant date.
 
     If a participant ceases to perform services for the Company due to death or
permanent disability while holding one or more outstanding options under the
Stock Option Plan, then each such option will remain exercisable for the limited
period of time (not to exceed twelve months after the date of such cessation of
service) specified by the Stock Option Plan Committee in the option agreement.
In the event a participant is terminated for cause, all outstanding options of
such participant automatically terminate on the participant's termination date.
If a participant ceases to perform services for the Company for any reason other
than death, permanent disability or termination for cause, any outstanding
option will remain exercisable for the limited period of time (not to exceed
three months after the date of such cessation of service) specified by the Stock
Option Plan Committee in the option agreement.
 
     Shares of Class A Common Stock that are issued upon exercise of options
granted under the Stock Option Plan are subject to certain repurchase rights of
the Company. If a participant ceases to perform services for the Company while
holding unvested shares, the Company has the right to repurchase, at the option
price paid per share, all or (at the discretion of the Company and with the
written consent of the participant) less than all of those unvested shares.
Until such time as the Company's outstanding shares of Class A Common Stock are
first registered under Section 12 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") (which will occur in connection with this
Offering), the Company retains a right of first refusal with respect to any
proposed sale or other disposition by a participant (or any successor in
interest by reason of purchase, gift or other mode of transfer) of any shares of
Class A Common Stock issued under the Stock Option Plan.

     In the event of (i) a merger or consolidation in which the Company is not
the surviving entity and in which securities possessing fifty percent (50%) or
more of the total combined voting power of the Company's outstanding voting
securities are transferred to a person or persons different from those who held
such securities immediately prior to such transaction, (ii) the sale, transfer
or other disposition of all or substantially all of the Company's assets other
than in the ordinary course of business, or (iii) any reverse merger in which
the Company is the surviving entity but in which securities possessing fifty
percent (50%) or more of the total combined voting power of the Company's
outstanding voting securities are transferred to a person or persons different
from those who held such securities immediately prior to such transaction, the
vesting of each option outstanding under the Stock Option Plan will
automatically accelerate so that each such option will become fully exercisable
immediately prior to the effective date of such corporate reorganization.
 
     As of March 31, 1996, 2,793,274 options were outstanding at exercise prices
ranging from $0.08 to $12.00 per share.

FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE STOCK OPTION PLAN
 
     There will be no federal income tax consequences to the employee or the
Company upon the grant of either an ISO or an NSO under the Stock Option Plan.
Upon exercise of an NSO, an employee will recognize ordinary income in an amount
equal to (i) the fair market value, on the date of exercise, of the acquired
shares of Class A Common Stock; less (ii) the exercise price of the NSO. Subject
to Section 162(m) of the Code and the employee including such compensation in
income or the Company satisfying applicable reporting requirements, the Company
will be entitled to a tax deduction in the same amount.
 
     If any profits associated with a sale of Class A Common Stock acquired
pursuant to the exercise of an NSO under the Stock Option Plan could subject the
optionee to liability under Section 16(b) of the Exchange Act, there will be no
concurrent federal income tax consequences to either the optionee or the Company
as a result of the exercise of such NSO. The inclusion of such profits as income
to the optionee is generally deferred until the date on which the Section 16(b)
restrictions terminate. However, if the optionee makes a timely and proper 83(b)
election to be taxed at the time such Class A Common Stock is transferred to
him, then the excess of the fair market value of the shares of Class A Common
Stock on the exercise date over the exercise price will be taxed as ordinary
income. An 83(b) election must be made within thirty days of the date of
exercise of the NSO. In the absence of such an election, the excess of the fair
market value of the shares of Class A Common Stock on the date the Section 16(b)
restrictions expire over the exercise price will be considered compensation
taxable as ordinary income to the optionee. The Company will be entitled to a
tax
 
                                       57
<PAGE>   58
 
deduction in an amount equal to the amount required to be recognized as ordinary
income by the optionee at the time the optionee is subject to tax.
 
     Upon the exercise of an ISO, an employee recognizes no immediate taxable
income. Income recognition is deferred until the employee sells the shares of
Class A Common Stock. If the ISO is exercised no later than three months after
the termination of the employee's employment, and the employee does not dispose
of the shares acquired pursuant to the exercise of the ISO within two years from
the date the ISO was granted and within one year after the exercise of the ISO,
the gain on the sale will be treated as long-term capital gain. Certain of these
holding periods and employment requirements are liberalized in the event of an
employee's death or disability while employed by the Company. The Company is not
entitled to any tax deduction with respect to the grant or exercise of ISOs,
except that if the Class A Common Stock is not held for the full term of the
holding period outlined above, the gain on the sale of such Class A Common
Stock, being the lesser of: (i) the fair market value of the Class A Common
Stock on the date of exercise minus the option price; or (ii) the amount
realized on disposition minus the exercise price, will be taxed to the employee
as ordinary income and, subject to Section 162(m) of the Code and the employee
including such compensation in income or the Company satisfying applicable
reporting requirements, the Company will be entitled to a deduction in the same
amount. The excess of the fair market value of the Class A Common Stock acquired
upon exercise of an ISO over the exercise price therefor constitutes a tax
preference item for purposes of computing the "alternative minimum tax" under
the Code.
 
STOCK ISSUANCE PLAN
 
     The Company's Third Amended and Restated 1991 Stock Issuance Plan (the
"Stock Issuance Plan") authorizes the issuance of Class A Common Stock to key
employees and directors and others deemed to provide valuable services to the
Company as additional compensation and to encourage them to continue to provide
service to the Company.
 
     The number of shares that may be issued over the term of the Stock Issuance
Plan (together with any shares for which options have been granted under the
Stock Option Plan) may not exceed 4,550,000 shares.
 
     Shares may, in the absolute discretion of the committee of the Board
responsible for administration of the Stock Issuance Plan (the "Stock Issuance
Plan Committee"), be issued for consideration with a value less than 100% of the
fair market value of the issued shares. Under no circumstances, however, may any
shares be issued for consideration valued by the Stock Issuance Plan Committee
at less than 85% of the fair market value of such shares at the time of
issuance.
 
     The interest of a participant in the shares of Class A Common Stock issued
under the Stock Issuance Plan may, in the absolute discretion of the Stock
Issuance Plan Committee, be fully vested upon issuance or may vest in one or
more installments. The participant, however, has all the rights of a shareholder
with respect to the shares of Class A Common Stock issued thereunder, whether or
not such participant's interest in such shares is vested. Accordingly, the
participant has the right to vote the shares and to receive any cash dividends
or other distributions paid or made with respect to the shares.
 
     If the participant ceases to perform services for the Company for any
reason while such participant's interest in the shares of Class A Common Stock
issued under the Stock Issuance Plan remains unvested, then the Company has the
right to repurchase, at the original purchase price paid by the participant, all
or (at the discretion of the Company and with the written consent of the
participant) less than all shares in which the participant is not at the time
vested. In the event of (i) a merger or consolidation in which the Company is
not the surviving entity and in which securities possessing fifty percent (50%)
or more of the total combined voting power of the Company's outstanding voting
securities are transferred to a person or persons different from those who held
such securities immediately prior to such transaction, (ii) the sale, transfer
or other disposition of all or substantially all of the Company's assets other
than in the ordinary course of business, or (iii) any reverse merger in which
the Company is the surviving entity but in which securities possessing fifty
percent (50%) or more of the total combined voting power of the Company's
outstanding voting securities are transferred to a person or persons different
from those who held such securities immediately prior to such
 
                                       58
<PAGE>   59
 
transaction, all of the Company's repurchase rights will automatically terminate
and all shares subject to such repurchase rights will become immediately vested
in full.
 
     The Stock Issuance Plan Committee may also require as a condition of the
issuance of one or more shares of Class A Common Stock under the Stock Issuance
Plan that the Company shall have a right of first refusal with respect to any
proposed disposition by the participant (or any successor in interest by reason
of purchase, gift or other mode of transfer) of one or more shares of such Class
A Common Stock.
 
     As of March 31, 1996, 300,000 shares of Class A Common Stock had been
issued pursuant to the Stock Issuance Plan, all of which were vested.
 
STOCK PURCHASE PLAN
 
     On March 28, 1996, the Board of Directors adopted, and the Company's
stockholders subsequently approved, the Company's Employee Stock Purchase Plan
(the "Stock Purchase Plan"). Under the Stock Purchase Plan, the Company will
grant to each eligible employee of the Company and affiliated companies options
to purchase shares of Class A Common Stock at not less than 90% of the fair
market value of such stock on the purchase date or the grant date, whichever is
less.
 
  PURPOSE
 
     The purpose of the Stock Purchase Plan is to provide an opportunity by
which all eligible employees may purchase shares of Class A Common Stock through
voluntary, systematic payroll deductions. By this means such employees are
provided with an opportunity to acquire an interest in the economic progress of
the Company and a further incentive to promote its best interests. The Stock
Purchase Plan, which is intended to qualify under Section 423 of the Code, is
not subject to any provisions of ERISA.
 
  AVAILABLE SHARES AND ELIGIBILITY
 
     The maximum aggregate number of shares of Class A Common Stock that may be
issued under the Stock Purchase Plan is 500,000. All individuals who have 6
months of continuous service with the Company or an affiliate with a regularly
scheduled work week of 20 hours or more, including officers and employee
directors (except for any employee owning 5% or more of the combined voting
power or value of all classes of the stock of the Company), are eligible to
participate in the Stock Purchase Plan.
 
  GRANT OF OPTIONS
 
     On each January 1 and July 1 of a plan year, each eligible employee will be
granted an option to purchase that number of shares of Class A Common Stock with
an aggregate fair market value that does not exceed $25,000 for such plan year.
Each option will be exercised, in its entirety, on June 30 or December 31 (or
immediately preceding business day if such day is not a business day) depending
on the date of grant, and only while the holder is an employee of the Company or
an affiliate. Options must be exercised on such June 30 or December 31, after
which time the option will expire. The initial grant date is July 1, 1996. The
initial purchase date is December 31, 1996. Thereafter, grant dates will be
January 1 and July 1, and purchase dates will be June 30 and December 31,
respectively, of any year. For employees who become eligible after January 1 of
any plan year but prior to July 1 of such year, the first grant date will be
July 1 of such plan year. For employees who become eligible after July 1 of a
plan year, the first grant date will be January 1 of the subsequent plan year.
Options are not transferable except by will or by the laws of descent and
distribution and may be exercised during the employee option-holder's lifetime
only by him or her.
 
  PAYMENT AND PAYROLL DEDUCTIONS
 
     Payment for shares is made through elective payroll deductions. The minimum
payroll deduction is $10 per pay period. Amounts deducted are accumulated in a
payroll deduction account, without interest. A participant may revoke or
decrease at any time his or her contribution to the payroll deduction account.
 
                                       59
<PAGE>   60
 
However, increases in a participant's contribution to his or her payroll
deduction account may not be made more than twice during any plan year and only
in January and July of such plan year.
 
  HOLDING PERIOD
 
     Participants in the Stock Purchase Plan will not sell, transfer or
otherwise dispose of any shares of Class A Common Stock purchased pursuant to an
exercise of an option to purchase granted under the Stock Purchase Plan for a
period of 180 days from the date such shares are purchased.
 
  NEW STOCK PURCHASE PLAN BENEFITS
 
     Since participation in the Stock Purchase Plan is voluntary, it is not
possible to estimate the actual dollar value and number of shares of Class A
Common Stock that will be purchased under the Stock Purchase Plan by the
executive officers named in the Summary Compensation Table, all executive
officers as a group and all employees as a group.
 
  FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE STOCK PURCHASE PLAN
 
     The following briefly summarizes the federal income tax consequences under
the Code of participation in the Stock Purchase Plan.
 
     An employee will not realize taxable income upon the grant of a right to
purchase shares or upon the purchase of shares pursuant to the terms of the
Stock Purchase Plan even though the price paid for the shares is less than their
fair market value. If an employee disposes of shares acquired under the Stock
Purchase Plan, the amount of ordinary income, capital gain or capital loss
realized will depend on the holding period of the shares.
 
     If the employee disposes of shares more than one year after the shares have
been transferred and more than two years after the date of grant, the employee
will realize ordinary income in the year of disposition equal to the lesser of
(i) 10% of the fair market value of the shares on the date of grant or (ii) the
amount by which the fair market value of the shares on the date of disposition
exceeds the purchase price. Any additional gain from the sale will be long-term
capital gain.
 
     If the shares are disposed of within either of the holding periods
described above (a disqualifying disposition), the employee will realize
ordinary income equal to the excess of the fair market value of the shares on
the date of purchase pursuant to the Stock Purchase Plan over the purchase
price. This excess is taxed as ordinary income even if the shares are sold at a
loss. In addition, the employee will have capital gain or loss measured by the
difference between (i) the sale price and (ii) the purchase price plus the
amount of ordinary income recognized.
 
     The Company generally is not entitled to an income tax deduction when an
employee exercises an option to purchase a share under the Stock Purchase Plan
or upon the subsequent disposition of any such share. If the disposition is a
disqualifying disposition, the Company will be entitled to an income tax
deduction in the year of such disposition in an amount equal to the amount of
ordinary income recognized by the employee as a result of such disposition.
 
DIRECTORS PLAN
 
     On March 28, 1996, the Board of Directors adopted, and the Company's
stockholders approved, the Non-Employee Directors Stock Option Plan (the
"Directors Plan"). The following is a summary of the material terms of the
Directors Plan, a copy of which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The following summary does not
purport to be complete and is qualified in its entirety by the terms of the
Directors Plan.
 
                                       60
<PAGE>   61
 
  PURPOSE
 
     The purpose of the Directors Plan is to attract and retain competent
non-employee personnel to serve on the Company's Board of Directors and to
increase their identification with the interests of the Company's stockholders.
 
  ADMINISTRATION
 
     The Directors Plan is administered by the Compensation Committee. Subject
to the provisions of the Directors Plan, the Compensation Committee has powers
and authorities which are exclusively ministerial in nature, including the
authority to construe and interpret the Directors Plan, to define the terms used
therein, to prescribe, amend and rescind rules and regulations relating to the
administration of the Directors Plan, and to make all other determinations
deemed necessary or advisable for the administration of the Directors Plan.
 
  AVAILABLE SHARES AND ELIGIBILITY
 
     The aggregate number of shares of Class A Common Stock of the Company that
may be issued upon the exercise of all options granted under the Directors Plan
may not exceed 100,000, subject to adjustment pursuant to certain corporate
transactions, such as recapitalizations, mergers or changes in control. Shares
of Class A Common Stock subject to options which terminate without having been
exercised in full may again be made available for purposes of the Directors
Plan. Each member of the Board of Directors who is not an employee of the
Company or any of its affiliates and does not own more than 1% of the Common
Stock of the Company (a "Non-Employee Director") is entitled to receive options
under the Directors Plan.
 
  TERMS AND CONDITIONS OF OPTIONS
 
     Each option granted under the Directors Plan will be a NSO. On the day a
Non-Employee Director is first elected and duly qualified as a member of the
Board (a "New Director") such New Director will receive an option to purchase
25,000 shares of Class A Common Stock. On each subsequent third anniversary of
the date of grant, each Non-Employee Director who was previously elected to the
Board and who continues to serve in such capacity, shall be granted an option to
purchase an additional 25,000 shares of Class A Common Stock.
 
     The exercise price of the Class A Common Stock covered by each option is
the fair market value of such shares on the date of grant of the option, subject
to any adjustments as described in the Directors Plan. Options are exercisable
as to 1/12 of the shares subject thereto on the last day of each calendar
quarter following the date of the grant, with an additional 1/12 of such grant
exercisable as of the last day of each calendar quarter subsequent thereto. An
option is exercisable for a period of ten years from the date of grant of the
option, subject to earlier termination as described in the Directors Plan.
 
     An optionee may exercise an option by giving written notice to the
Compensation Committee together with payment in full of the exercise price. Such
payment may be made in certified or bank check or cash or in the form of such
other compensation as approved by the Compensation Committee. Options may be
exercised, during the lifetime of the optionee, only by the optionee or by his
guardian or legal representative.
 
     Except as otherwise provided below, an option may not be exercised unless
the optionee is then a director of the Company and unless he has remained
continuously in the Company's service as a director since the date of the grant
of the option. Notwithstanding the foregoing, upon termination of a director's
service for any reason other than death, disability or cause (as described in
the Directors Plan), options will be exercisable, to the extent otherwise
exercisable on such date, for 60 days after such termination, unless earlier
terminated in accordance with their terms. Upon termination of service for
cause, unexercised options terminate immediately. Upon termination of service by
reason of death or disability, options will be exercisable, to the extent
otherwise exercisable on such date, at any time within one year after the date
of death or disability, unless earlier terminated in accordance with their
terms. In the event of death or disability of the optionee, options may be
exercised by the optionee's estate or by a person who acquired the right to
exercise such option by bequest or inheritance or otherwise by reason of the
death or disability of the optionee.
 
                                       61
<PAGE>   62
 
  AMENDMENT AND TERMINATION
 
     The Board of Directors may at any time and from time to time, suspend,
terminate, modify or amend the Directors Plan; provided, however, that the
Directors Plan shall not be amended more than once during any six-month period
other than to comply with applicable law. Further, certain amendments shall be
subject to approval by the stockholders of the Company. Except as otherwise
provided in the Directors Plan, no suspension, termination, modification or
amendment of the Directors Plan may adversely affect any option previously
granted, unless the written consent of the optionee is obtained. The Directors
Plan is not subject to any provision of ERISA and is not qualified under Section
401(a) of the Code.
 
  NEW DIRECTORS PLAN BENEFITS
 
     Grants of options under the Directors Plan are determined by formula as set
forth therein. Currently, no director of the Company is eligible to participate
in the Directors Plan.
 
  CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Under present law, an optionee who is granted an NSO under the Directors
Plan will not be subject to federal income tax upon the grant, and the Company
will not be entitled to a tax deduction by reason of such grant. When the
optionee exercises the NSO, the excess of the fair market value of the shares
acquired on the exercise date over the exercise price will be considered
compensation taxable as ordinary income to the optionee, and the Company may
claim a tax deduction at that time equal to the amount of taxable income
realized by the optionee.
 
     If any profits associated with a sale of Class A Common Stock acquired
pursuant to the exercise of an NSO under the Directors Plan could subject the
optionee to liability under Section 16(b) of the Exchange Act, there will be no
concurrent federal income tax consequences to either the optionee or the Company
as a result of the exercise of such NSO. The inclusion of such profits as income
to the optionee is generally deferred until the date on which the Section 16(b)
restrictions terminate. However, if the optionee makes a timely and proper 83(b)
election to be taxed at the time such Class A Common Stock is transferred to
him, then the excess of the fair market value of the shares of Common Stock on
the exercise date over the exercise price will be taxed as ordinary income. An
83(b) election must be made within thirty days of the date of exercise of the
NSO. In the absence of such an election, the excess of the fair market value of
the shares of Common Stock on the date the Section 16(b) restrictions expire
over the exercise price will be considered compensation taxable as ordinary
income to the optionee. The Company will be entitled to a tax deduction in an
amount equal to the amount required to be recognized as ordinary income by the
optionee at the time the optionee is subject to tax.
 
     Upon the sale of any shares acquired pursuant to the exercise of an NSO
granted under the Directors Plan, an optionee will recognize gain in an amount
equal to the difference between the sales price and the optionee's tax basis in
such shares, which tax basis will include the exercise price paid plus the
amount required to be recognized as income by the optionee as a result of the
exercise of the NSO. Such gain will be short-term capital gain if the shares
have been held for twelve months or less and long-term capital gain if the
shares have been held for more than twelve months.
 
     The above tax information is only a brief summary of the federal income tax
consequences resulting from the receipt and/or exercise of NSOs. It is based on
present federal tax laws and regulations and does not purport to be a complete
description of such federal income tax consequences. The foregoing summary of
federal income tax consequences may change if the Code or regulations
promulgated thereunder are changed.

                              CERTAIN TRANSACTIONS
 
RELATED PARTY TRANSACTIONS
 
     The Company was organized in 1989 by Roger D. Linquist, MSVCF, Accel
Telecom L.P., Accel Partners L.P. and Frances W. Hopkins. Through the
acquisition of preferred stock in 1991 and 1993, MSLEF II became the owner of
capital stock representing a majority of the voting power in the Company. The
general partner of MSLEF II and the managing general partner of the general
partner of MSVCF are both wholly owned subsidiaries of MS Group. Four of the
eight directors of the Company are employees of MS & Co. MS & Co. acted as
placement agent for the offering of the 12 1/4% Notes and the offering of the
15% Notes and received compensation from the Company in the amount of $2.6
million and $3.8 million, respectively, for acting in such capacity. MS & Co. is
acting as an underwriter in the Offering.
 
     In two transactions consummated in March and May of 1993, the Company
issued a total of 5,277,611 shares of the Company's Series C Preferred Stock,
having an aggregate liquidation preference of $17,205,011, for an aggregate
purchase price of $17,205,011, of which 5,214,724 shares were issued to MSLEF
II. During the fiscal quarter ended September 30, 1994, the Company issued an
aggregate of 11,242,857 shares of Common Stock in the 1994 Stock Offerings at a
purchase price of $7.00 per share. The aggregate net proceeds (after expenses)
of the 1994 Stock Offerings were approximately $76.9 million. Of the shares
issued in the 1994 Stock Offerings, 5,000,000 shares of Common Stock were issued
to MSCP III, Morgan Stanley Capital Investors, L.P. ("MSCI"), MSVCF II, Morgan
Stanley Venture Capital Fund II, C.V. ("MSVC II"), and Morgan Stanley Venture
Investors, L.P. ("MSVI"), 2,857,143 shares were issued to First Plaza Group
Trust and 1,242,857 shares to certain other institutional investors. The
remaining 2,142,857 shares of the Common Stock issued in the 1994 Stock
Offerings were acquired by an affiliate of Pulsar pursuant to a private
placement.
 
     On May 11, 1995, the Company completed the issuance of 3,598,429 shares of
Common Stock in the 1995 Private Stock Offering at a purchase price of $7.00 per
share. The net proceeds (after expenses) of the 1995 Private Stock Offering were
approximately $24.5 million. Of the shares issued in the 1995 Private Stock
Offering, 2,277,286 were purchased by the MS Merchant Banking Funds (as defined
herein), other than MSLEF II, and 357,143 shares were purchased by First Plaza
Group Trust. The remaining 964,000 shares of Common Stock were purchased by
other institutional investors and the following officers of the Company: John D.
Beletic (3,000 shares), Daniel W. Hay (1,000 shares), G. Clay Myers (5,000
shares), Todd A. Bergwall (1,000 shares), Lawrence H. Wecsler (1,000 shares),
Paul L. Turner (1,000 shares), Kenneth L. Hilton (18,000 shares) and Douglas H.
Kramp (15,000 shares).
 
     In October 1995, MSLEF II, MSCP III, MSCI, MSVCF, MSVCF II, MSVC II, MSCP
892 Investors, L.P. ("MSCP 892"), and MSVI (collectively, the "Morgan Stanley
Shareholders") exchanged a portion of their Class A Common Stock of the Company
for Class B Common Stock in a share-for-share exchange without payment of any
additional consideration. See "Risk Factors -- Significant Ownership."
 
     As of March 31, 1996, John D. Beletic, President of the Company, was
indebted to the Company in the amount of $118,800 under three promissory notes.
The first promissory note (the "First Note") was issued in January 1994 for
$97,800 in connection with a stock option exercise by Mr. Beletic and bears
interest at the rate of 3.55% per annum. Interest on the outstanding balance is
due and payable annually beginning on January 28, 1995. The outstanding
principal balance on the First Note is due and payable on January 28, 1999. The
second promissory note (the "Second Note") was issued in November 1994 and bears
interest at the rate of 7% per annum. Under the terms of the Second Note, Mr.
Beletic may receive loans in various amounts, the total of which may not exceed
$200,000. There were no amounts outstanding under the Second Note at March 31,
1996. The third promissory note (the "Third Note") was issued in May 1995 for
$21,000 in connection with the purchase of Class A Common Stock by Mr. Beletic
and bears interest at the rate of 6.9% per annum. Interest on the outstanding
principal is due and payable annually beginning on May 11, 1996. The outstanding
principal balance on the Third Note is due and payable on May 11, 1999. The
First Note, the Second Note and the Third Note are all secured by the Class A
Common Stock owned by Mr. Beletic.

ELECTION OF DIRECTORS
 
     Pursuant to the Stockholders Agreement, the Morgan Stanley Shareholders
have the right to designate and have elected one-half of the members of the
Board of Directors of the Company for so long as the total number of shares of
Common Stock of the Company owned by the Morgan Stanley Shareholders constitutes
at least 50% of the outstanding Common Stock of the Company. If such ownership
falls below 50%, the number of directors that the Morgan Stanley Shareholders
will have the right to designate and have elected will be reduced to the number
of directors which constitutes a percentage representation on the Board equal to
the Morgan Stanley Shareholders' aggregate percentage ownership of the
outstanding Common Stock of the Company. The rights of each of MSLEF II, MSCP
III, MSVCF and MSVCF II to designate and have elected one member of the Board of
Directors terminates once the total number of shares of Common Stock of the
Company owned by such investor falls below 7.5%. However, each such stockholder
will continue to have such rights if its ownership of Common Stock exceeds 2%
and such stockholder has determined that the continued possession of such rights
is necessary or desirable in order for such stockholder to qualify as a "venture
capital operating company" within the meaning of Department of Labor Regulation
Section 2510.3-101. MSVCF has made such a determination and continues,
therefore, to have the right to designate and have elected one director. After
giving effect to the Offering, the Morgan Stanley Shareholders will own 51.3% of
the Common Stock of the Company (50.1% if the Underwriters' over-allotment
option is exercised in full) and 38.9% of the voting Common Stock (37.7% if the
Underwriters' over-allotment is exercised in full). The Morgan Stanley
Shareholders have informed the Company that they intend, upon the consummation
of the Offering, to convert such number of their shares of non-voting Common
Stock so that, following such conversion, the Morgan Stanley Shareholders will
own, in the aggregate, 49% of the outstanding voting Common Stock of the
Company.
 
     Accel Telecom L.P., Accel III, L.P. and Accel Investors 89, L.P.
(collectively, "Accel") also has the right to designate one director for
election to the Board of Directors so long as Accel owns at least 7.5% of the
outstanding Common Stock of the Company. So long as Pulsar owns at least 5% of
the outstanding capital stock of the Company (or until the expiration of the
Pulsar Exclusivity Period, as defined in the Stockholders' Agreement), it will
have the right to designate one member of the Board of Directors.
 
     So long as J.P. Morgan Capital Corporation ("Morgan Capital") owns no less
than 4% of the Common Stock of the Company, the Company will permit a
representative of such holder to attend as an observer all meetings of the Board
of Directors of the Company and all committees thereof. Such representative is
entitled to receive all written materials and other information given to
directors in connection with such meetings.
 
     So long as the Morgan Stanley Shareholders hold securities representing at
least 10% of the outstanding Common Stock, the Company is required to maintain
compensation and audit committees of its Board of Directors, each consisting of
up to four directors. Accel and those members of the Board of Directors who are
not designated by the Morgan Stanley Shareholders are each entitled to designate
one director on each such committee and the Morgan Stanley Shareholders are
entitled to designate up to two directors on each such committee.
 
     The Company will not amend the Company's Restated Certificate of
Incorporation or By-laws to eliminate the right of stockholders of the Company
to take action upon written consent without a meeting, without prior notice and
without a vote as provided in the Company's By-laws, so long as the MS Merchant
Banking Funds hold at least 7.5% of the Company's Common Stock.
 
REGISTRATION RIGHTS
 
     The Stockholders Agreement provides that the parties thereto, which include
substantially all of the current stockholders of the Company (collectively, the
"Holders"), collectively have the right to "demand" an unlimited number of
registrations at any time at least six months after this Offering. The Company
will bear the costs and expenses of such "demand" registrations. Pursuant to
these "demand" rights, Holders of Common Stock (the "Registrable Securities")
may request in writing that the Company file a registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), covering the
registration of a number of shares equal to at least three million shares of
Common Stock or a lesser number if such number
 
                                       64
<PAGE>   65
 
represents a majority of the Registrable Securities then outstanding. The
Company is obligated within ten days of the receipt thereof to give written
notice of such request to all Holders and to use its best efforts to effect as
soon as practicable the registration under the Securities Act of all Registrable
Securities that the Holders request to be registered within 20 days of such
notice by the Company. Unless the Holders of a majority of the Registrable
Securities to be registered shall consent in writing, no other party (including
the Company) will be permitted to offer securities under such demand
registration. Under certain circumstances, Pulsar may also request that the
Company file a registration under the Securities Act covering the registration
of all of the Registrable Securities Pulsar owns. Pulsar may make no more than
two such requests. The Company is not obligated to effect more than one demand
registration in any six-month period.
 
     In the event the managing underwriter advises the Holders that the size of
the offering is such that the success of the offering would be materially and
adversely affected by inclusion of all Registrable Securities requested to be
included, then the number of shares of Registrable Securities to be included in
the underwriting will be reduced on a pro rata basis, provided that the Company
will first reduce entirely all securities other than Registrable Securities to
be included in such underwriting.
 
     The Stockholders Agreement also provides that, if the Company proposes to
register any of its stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than this Offering), the Company shall, at such time, promptly (but in no event
less than 30 days before the filing date) give each Holder written notice of
such registration, and such notice shall offer the Holders the opportunity to
register such number of shares of Registrable Securities as such Holder may
request. Subject to certain restrictions, upon the written request of each
Holder given within 20 days after delivery of such notice by the Company, the
Company shall cause to be registered under the Securities Act all of the
Registrable Securities that each such Holder has requested to be registered.
 
     If the underwriters determine that the total amount of securities requested
to be included in any such offering would materially and adversely affect the
success of such offering, the Company will be required to include in the
offering, in addition to any shares to be registered by the Company, only that
number of such Registrable Securities that the underwriters determine in their
sole discretion would not affect the success of such offering.
 
RESTRICTIONS ON TRANSFER
 
     Under the Stockholders Agreement, if MSLEF II, MSCI, MSCP 892 and MSCP III
(collectively, the "MS Merchant Banking Funds") propose to transfer (other than
in a sale to the public) shares which, taken together with any prior transfers
by the MS Merchant Banking Funds, represent more than 10% of the shares owned by
them on the date of the Stockholders Agreement, the Holders have a right to
require the transferee to purchase their shares on a pro rata basis. The Holders
(other than Morgan Capital) who own at least 67% of the voting Common Stock (the
"Compelling Holders") also have the right to require all Holders (other than
Morgan Capital) to sell their shares to any third party that buys all of the
shares owned by the Compelling Holders.
 
     The Stockholders Agreement further provides for certain restrictions on the
amount of Common Stock which may be transferred by the parties to the
Stockholders Agreement for a period of one year following any public offering of
the Company's Common Stock (including this Offering), based on, with certain
exceptions, the percentage of shares of Common Stock sold in any such offering
by certain institutional investors party to the Stockholders Agreement (the
"Transfer Restrictions"). These restrictions on transfer, and the right of the
Compelling Holders described above, will terminate, subject to certain
extensions, approximately one year following the consummation of the Offering.
The Stockholders Agreement also provides for certain restrictions on the
transfer of shares of Common Stock by holders thereof subject to Regulation Y of
the Board of Governors of the Federal Reserve System (the "Regulation Y
Restriction"). None of the foregoing provisions of the Stockholders' Agreement
apply to Morgan Capital. Morgan Capital has, however, entered into a separate
agreement with the Company pursuant to which Morgan Capital is subject to
restrictions which are nearly identical to the Transfer Restrictions and the
Regulation Y Restriction.

RESTRICTIONS ON AMENDMENT OF CERTIFICATE OF INCORPORATION
 
     The Company will not amend the Company's Amended and Restated Certificate
of Incorporation or By-laws to eliminate the right of stockholders of the
Company to take action upon written consent of the holders of a majority of the
outstanding shares of Class A Common Stock without a meeting, without prior
notice and without a vote as provided in the Company's By-laws, so long as the
MS Merchant Banking Funds hold at least 7.5% of the Company's Common Stock. See
"Description of Capital Stock."

 (1) Each share of Class B and C Common Stock is convertible by certain
     institutional investors subject to certain voting control and regulatory
     restrictions at the option of the holder into one share of Class A Common
     Stock. Each share of Class D Common Stock is convertible, at the option of
     the holder, at any time following the completion of this Offering, into one
     share of Class A Common Stock. See "Description of Capital Stock -- Common
     Stock." The number of shares of Class A Common Stock and percentages under
     this heading do not account for such conversion rights, although the
     intended conversion of certain shares of Class B Common Stock and Class C
     Common Stock into Class A Common Stock is reflected under the heading Class
     A Common Stock to be Owned After the Offering. See footnote (2) below.
 
 (2) Holders of Class B, C and D Common Stock have no voting power except under
     certain limited exceptions. See "Description of Capital Stock." The Morgan
     Stanley Shareholders have informed the Company that they intend, upon the
     consummation of the Offering, to convert their shares of non-voting Common
     Stock so that, following such conversion, the Morgan Stanley Shareholders
     will own, in the aggregate, 49% of the outstanding voting Common Stock of
     the Company. In addition, Morgan Capital has informed the Company that it
     intends to convert all but 100 shares of Class A Common Stock held directly
     or indirectly by it into Class C Common Stock immediately prior to the
     effectiveness of the Registration Statement of which this Prospectus forms
     a part. Amounts under the heading Class B, C and D Common Stock to be Owned
     After the Offering reflect such intended conversions.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The following summary of the Company's capital stock does not purport to be
complete and is subject to and qualified in its entirety by the Company's
Amended and Restated Certificate of Incorporation, as amended (the
"Certificate"), and the laws of the State of Delaware.
 
     The Certificate authorizes the issuance of 85,000,000 shares of Capital
Stock, consisting of 60,000,000 shares of Class A Common Stock, 12,000,000
shares of Class B Common Stock, 2,000,000 shares of Class C Common Stock,
1,000,000 shares of Class D Common Stock and 10,000,000 shares of preferred
stock. As of March 31, 1996, 23,278,915 of the authorized shares of Class A
Common Stock were outstanding, 8,975,469 of the authorized shares of Class B
Common Stock were outstanding, 731,846 of the authorized shares of Class C
Common Stock were outstanding, 725,445 of the authorized shares of Class D
Common Stock were outstanding and none of the authorized shares of Preferred
Stock were outstanding. As of March 31, 1996, there were 97 holders of Class A
Common Stock, eight holders of Class B Common Stock, one holder of Class C
Common Stock and one holder of Class D Common Stock. As of March 31, 1996,
2,793,274 shares of Class A Common Stock were reserved for issuance upon
exercise of outstanding stock options, 627,900 shares of such stock were
reserved for issuance upon exercise of the warrants issued by the Company in
1993 in connection with the placement of the 12 1/4% Notes (the "1993
Warrants"), 714,286 shares of such stock were reserved for issuance upon
conversion of securities by unaffiliated third-party Canadian stockholders of
Canada Holding and 206,748 shares of such stock were reserved for issuance on
exercise of the warrants issued to Mitsui Co., Ltd. in 1995 (the "Mitsui
Warrants"). See "Management -- Stock Option Plan," "Management -- Stock Issuance
Plan" and " -- Warrants."
 
COMMON STOCK
 
     Class A Common Stock. Holders of Class A Common Stock are entitled to one
vote for each share of Class A Common Stock held on each matter submitted to a
vote of stockholders, including the election of directors. Holders of Class A
Common Stock are not entitled to cumulative voting. Shares of Class A Common
Stock have no preemptive or other subscription rights and are convertible
(except as provided in the Stockholders Agreement) (i) by the Morgan Stanley
Shareholders into an equal number of shares of Class B Common Stock and (ii) by
Morgan Capital and BT Investment Partners, Inc. (together, the "Regulated
Shareholders") into an equal number of shares of Class C Common Stock.
 
     Class B Common Stock. Holders of the Class B Common Stock have no right to
vote on matters submitted to a vote of stockholders, except (i) as otherwise
required by law and (ii) that the holders of Class B Common Stock shall have the
right to vote as a class on any amendment, repeal or modification to the
Certificate that adversely affects the powers, preferences or special rights of
the holders of such class. Shares of Class B Common Stock have no preemptive or
other subscription rights and are convertible into an equal number of shares of
Class A Common Stock (x) at the option of the holder thereof to the extent the
Morgan Stanley Shareholders do not, in the aggregate, own more than 49% of the
outstanding shares of Class A Common Stock and (y) automatically upon the
transfer by any Morgan Stanley Shareholder of such shares to a person that is
not a Morgan Stanley Shareholder or an affiliate of a Morgan Stanley
Shareholder.
 
     Class C Common Stock. Holders of the Class C Common Stock have no right to
vote on matters submitted to a vote of stockholders, except (i) as otherwise
required by law and (ii) that the holders of Class C Common Stock shall have the
right to vote as a class on any amendment, repeal or modification to the
Certificate that adversely affects the powers, preferences or special rights of
the holders of such class. Shares of Class C Common Stock have no preemptive or
other subscription rights and are convertible, at the option of the holder
thereof, into an equal number of shares of Class A Common Stock but only to the
extent such holder and its affiliates would not, as a result of such conversion,
own, control or have the power to vote a greater number of shares of Class A
Common Stock than such holder and its affiliates are permitted to own, control
or have the power to vote under Regulation Y of the Board of Governors of the
Federal Reserve System (12 C.F.R. part 225) ("Regulation Y").
 
                                       70
<PAGE>   71
 
     Class D Common Stock. Holders of the Class D Common Stock have no right to
vote on matters submitted to a vote of stockholders, except (i) as otherwise
required by law and (ii) that the holders of Class D Common Stock shall have the
right to vote on any merger, consolidation or disposition of assets that
requires stockholder approval under Delaware law, in which case holders of Class
D Common Stock shall vote (at a rate of one vote per share of Class D Common
Stock held) with holders of Common Stock as a single class on such matter unless
otherwise required by law. Shares of Class D Common Stock have no preemptive or
other subscription rights and are convertible, at the option of the holder
thereof, into an equal number of shares of Class A Common Stock at any time
after the consummation of the Offering.
 
     Conversion of the Class B Common Stock, the Class C Common Stock and the
Class D Common Stock into shares of Class A Common Stock would result in a
decrease in the voting power of the holders of the previously outstanding Class
A Common Stock and the holders of the Class A Common Stock offered hereby.
 
     Dividends. All holders of Common Stock are entitled to receive such
dividends or other distributions, if any, as may be declared from time to time
by the Board of Directors in its discretion out of funds legally available
therefor, subject to the prior rights of any preferred stock then outstanding,
and to share equally, share for share, in such dividends or other distributions
as if all shares of Common Stock were of a single class. Dividends or other
distributions declared or paid in shares of Common Stock, or options, warrants
or rights to acquire such stock or securities convertible into or exchangeable
for shares of such stock, are payable to all of the holders of Common Stock
ratably according to the number of shares held by them, in shares of Class A
Common Stock to holders of that class of stock, Class B Common Stock to holders
of that class of stock, Class C Common Stock to holders of that class of stock,
and Class D Common Stock to holders of that class of stock.
 
     Liquidation. Subject to the prior rights of holders of all classes of stock
outstanding having prior rights with respect to the assets of the Company, upon
the liquidation or dissolution of the Company, the holders of Common Stock are
entitled to share ratably according to the number of shares held by them in all
assets remaining available for distribution to stockholders.
 
     Full Payment and Nonassessability. All outstanding shares of Common Stock
are, and the shares to be issued by the Company pursuant to the Offering will
be, fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Board of Directors, without further stockholder authorization, is
authorized to issue additional shares of preferred stock in one or more class or
series and to fix the rights, preferences and privileges of each additional
class or series, including dividend rights and preferences over dividends on the
Common Stock, conversion rights, voting rights (in addition to those provided by
law), redemption rights and the terms of any sinking fund therefor, and rights
upon liquidation, including preferences over the Common Stock. The issuance of
any such preferred stock may have the effect of delaying or preventing
transactions involving a change of control of the Company, including
transactions in which stockholders might otherwise receive a substantial premium
for their shares over then current market prices, and may limit the ability of
the stockholders to approve transactions that they deem to be in their best
interests.
 
CERTAIN REDEMPTION RIGHTS
 
     Under the Certificate, the Company has the right to redeem outstanding
shares of its capital stock if the Board of Directors determines that such
redemption is necessary to prevent the loss or secure the reinstatement of any
governmental license or franchise held by the Company at a price equal to the
current market value of such shares (as determined in accordance with the
Certificate). For example, if at any time the percentage of the Company's
outstanding capital stock owned by persons or entities that are not U.S. persons
under the FCC rules ("Non-U.S. Persons") were to exceed 25%, the Company could
redeem shares of the Company's capital stock held by Non-U.S. Persons. If the
Company were to redeem shares of its stock in order to comply with regulatory
restrictions, the shares to be redeemed would be selected in a manner determined
by the Board of Directors, which may include selection first of the most
recently purchased shares,
 
                                       71
<PAGE>   72
 
selection by lot or selection in any other manner determined by the Board of
Directors. Based on currently available information, the Company estimates that
its percentage of foreign ownership is approximately 22%.
 
WARRANTS
 
     In 1993, the Company issued the 1993 Warrants to purchase Common Stock at
an exercise price of $3.26 per share as part of the placement of the 12 1/4%
Notes. The 1993 Warrants may be exercised in whole or in part at any time until
December 31, 2003. The 1993 Warrants are currently exercisable for 627,900
shares of Class A Common Stock. In 1995, the Company issued to Mitsui Co., Ltd.
the Mitsui Warrants to purchase Common Stock at an exercise price of $10.00 per
share. The Mitsui Warrants may be exercised in whole or in part starting on
March 20, 1997 and until March 20, 2005. The Mitsui Warrants will be exercisable
for 206,748 shares of Class A Common Stock. The number of shares covered by the
1993 Warrants and the Mitsui Warrants may be adjusted on the occurrence of
certain events, specifically including, in the case of the 1993 Warrants, the
issuance of securities of the Company at less than fair market value (as defined
therein), or certain dividends, distributions or recapitalizations with respect
to the Class A Common Stock. See "Shares Eligible for Future Sale."
 
LIMITATION ON DIRECTORS' LIABILITY
 
     The Certificate provides that the Company's directors are not liable to the
Company or its stockholders for monetary damages for breach of their fiduciary
duties to the fullest extent permitted by Delaware law. Under existing Delaware
law, directors would not be liable except under certain circumstances, including
breach of the director's duty of loyalty, acts or omissions not in good faith or
involving intentional misconduct or a knowing violation of law or any
transaction from which the director derived improper personal benefit. The
inclusion of this provision in the Certificate may have the effect of reducing
the likelihood of derivative litigation against directors and may discourage or
deter stockholders or the Company from bringing a lawsuit against directors of
the Company for breach of their duty of care. However, the provision does not
affect the availability of equitable remedies such as an injunction or
rescission.
 
DELAWARE TAKEOVER STATUTE
 
     Section 203 of the Delaware Corporation Law, as amended ("Section 203"),
provides that, subject to certain exceptions specified therein, an "interested
stockholder" of a Delaware corporation shall not engage in any business
combination, including mergers or consolidations or acquisitions of additional
shares of the corporation with the corporation for a three-year period following
the date that such stockholder becomes an "interested stockholder" unless (i)
prior to such date, the board of directors of the corporation approved either
the business combination or the transaction which resulted in the stockholder
becoming an "interested stockholder", (ii) upon consummation of the transaction
which resulted in the stockholder becoming an "interested stockholder", the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding certain shares) or
(iii) on or subsequent to such date, the business combination is approved by the
board of directors of the corporation and authorized at an annual or special
meeting of stockholders by the affirmative vote of at least 66 2/3% of the
outstanding voting stock which is not owned by the "interested stockholder."
Except as otherwise specified in Section 203, an "interested stockholder" is
defined to include (x) any person that is the owner of 15% or more of the
outstanding voting stock of the corporation, or is an affiliate or associate of
the corporation and was the owner of 15% or more of the outstanding voting stock
of the corporation at any time within three years immediately prior to the
relevant date and (y) the affiliates and associates of any such person.
 
     These provisions could have the effect of delaying, deferring or preventing
a change of control of the Company. The Company's stockholders, by adopting an
amendment to its Certificate or bylaws, may elect not to be governed by Section
203, effective twelve months after adoption. Neither the Certificate nor the
By-laws presently exclude the Company from the restrictions imposed by Section
203.
 
REGISTRAR AND TRANSFER AGENT
 
     KeyCorp Shareholder Services, Inc., is the Registrar and Transfer Agent for
the Company's Class A Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have outstanding
39,713,226 shares of Common Stock (40,613,226 shares if the Underwriters'
over-allotment option is exercised in full). Upon completion of the Offering and
after giving effect to the intended conversion of shares of Class B Common Stock
and Class C Common Stock by certain holders thereof, the Company will have
outstanding 33,733,260 (34,633,260 if the Underwriters' over-allotment option is
exercised in full) shares of Class A Common Stock, 3,826,049 shares of Class B
Common Stock, 1,428,472 shares of Class C Common Stock, and 725,445 shares of
Class D Common Stock. See "Principal Stockholders." Shares of Class B, C and D
Common Stock are convertible, subject to certain ownership and regulatory
restrictions, at the option of the holder into an equal number of shares of
Class A Common Stock. Shares of Class A Common Stock held by the Morgan Stanley
Shareholders are convertible into an equal number of shares of Class B Common
Stock and shares of Class A Common Stock held by the Regulated Shareholders are
convertible into an equal number of shares of Class C Common Stock. The Company
has outstanding 2,793,274 options to purchase shares of Class A Common Stock
pursuant to the Stock Option Plan. In 1995, 36,654 shares of Class A Common
Stock were issued upon the exercise of options granted pursuant to the Stock
Option Plan. Approximately 32,387 of such shares were registered pursuant to a
Form S-8 registration statement. However, the shares registered under the Form
S-8 are subject to certain transfer restrictions contained in the stock purchase
agreement executed by each optionee upon exercise of each option. In addition,
834,648 shares of Common Stock are issuable upon the exercise of outstanding
warrants. See "Description of Capital Stock." Of such shares, the Company
intends to file a registration statement under the Securities Act to register
627,900 shares of Common Stock issuable upon exercise of the 1993 Warrants, thus
permitting resale of such shares in the public market without restriction under
the Securities Act. The agreement governing such warrants provides that the
Company will not cause such registration statement to become effective for a
period of 180 days after the date of this Prospectus without MS & Co.'s prior
written consent. Only the 6,000,000 shares sold in the Offering will be freely
transferable in the United States without restriction under the Securities Act
unless such shares of Common Stock are held by an "affiliate" of the Company (as
that term is defined under the rules and regulations of the Securities Act). Any
such affiliate will be subject to the resale limitations of Rule 144 adopted
under the Securities Act in the event such affiliate desires to publicly dispose
of such shares. Restricted securities may not be resold except in compliance
with the registration requirements of the Securities Act or pursuant to an
exemption therefrom, such as the exemptions provided by Rule 144 and Rule 144A.
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an affiliate, who has beneficially owned
"restricted securities" for at least two years will be entitled to sell within
any three-month period a number of shares that does not exceed the greater of
(i) 1% of the then outstanding shares of Common Stock (approximately 397,117
shares immediately after the Offering) and (ii) the average weekly trading
volume in the Common Stock on all national securities exchanges and/or reported
through the automated quotation system of registered securities associations
during the four calendar weeks immediately preceding the date on which notice of
the sale is filed with the Securities and Exchange Commission (the
"Commission"). Sales pursuant to Rule 144 are also subject to certain other
requirements regarding the manner of sale, notice and availability of current
public information about the Company. A person (or persons whose shares are
aggregated) who is not deemed to have been an affiliate of the Company at any
time during the three months immediately preceding the sale is entitled to sell
restricted securities pursuant to Rule 144(k) without regard to the limitations
described above, provided that three years have expired since the later of the
date on which such restricted securities were acquired from the Company or the
date they were acquired from an affiliate of the Company. As defined in Rule
144, an "affiliate" of an issuer is a person that directly, or indirectly
through one or more intermediaries, controls or is controlled by, or is under
common control with, such issuer. The Commission has proposed reducing the
periods of beneficial ownership of "restricted securities" required by Rule 144.
Under the proposal, persons who have beneficially owned restricted securities
for at least one year instead of two years as currently required, would be able
to resell such securities by complying with the volume limitations described
above. In the case of a person who is not deemed to be an affiliate of the
Company during the preceding three months, the proposal would permit sales
without regard to the limitations described above as long as such person had
held the securities for at least two years, instead of three years as currently
required. There can be no assurance that the proposed revisions to Rule 144 will
be adopted by the Commission.

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to take
and pay for all of the shares of Common Stock offered hereby (other than those
covered by the Underwriters' over-allotment option described below) if any such
shares are taken.
 
     The Underwriters propose to offer part of the Common Stock directly to the
public at the Price to Public set forth on the cover page hereof and part to
certain dealers at a price that represents a concession not in excess of $.55
per share under the public offering price. The Underwriters may allow, and such
dealers may reallow, a concession not in excess of $.10 per share to other
Underwriters or to certain other dealers. After the initial offering of the
Common Stock, the offering price and other selling terms may from time to time
be varied by the Underwriters.
 
     The Company has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.
 
     Each Underwriter has represented and agreed that (i) it has not offered or
sold and during the period of six months from the date hereof will not offer or

Regulations 1995 (the "Regulation"); (ii) it has complied and will comply with
all applicable provisions of the Financial Services Act of 1986 and the
Regulation with respect to anything done by it in relation to the shares in,
from or otherwise involving the United Kingdom; and (iii) it has only issued or

1986 (Investment Advertisements) (Exemptions) Order 1995 or is a person to whom
such document may otherwise lawfully be issued or passed on.
 
     Pursuant to the Underwriting Agreement, the Company has granted to the
Underwriters an option, exercisable for 30 days from the date of this
Prospectus, to purchase up to 900,000 additional shares of Common Stock at the
Price to Public set forth on the cover page hereof, less underwriting discounts
and commissions. The Underwriters may exercise such option to purchase solely
for the purpose of covering over-allotments, if any, made in connection with the
offering of the shares of Common Stock hereby. To the extent such option is
exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number set forth next to such Underwriter's name in the preceding
table bears to the total number of shares of Common Stock offered by the
Underwriters hereby.
 
     The Company, all of the Company's executive officers and directors, and
certain other shareholders of the Company who own in the aggregate approximately
32.6 million shares of Common Stock, have agreed that, without the prior written
consent of MS & Co. they will not (a) offer, pledge, sell, contract to sell,
sell any option or contract to purchase, purchase any option or contract to
sell, grant any option, right or warrant to purchase, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock (whether such
shares or any such securities are then owned by such person or are thereafter
acquired directly from the Company), or (b) enter into any swap or similar
agreement that transfers, in whole or in part, any of the economic consequences
of ownership of the Common Stock, whether any such transaction described in
clause (a) or (b) of this paragraph is settled by delivery of such Common Stock
or such other securities, in cash or otherwise, for a period of 180 days after
the date of this Prospectus, other than (i) the sale to the Underwriters of the
shares of Common Stock under the Underwriting Agreement, (ii) the issuance by
the Company of shares of Common Stock upon the exercise of an option or warrant
or the conversion of a security outstanding on the date of this Prospectus, or
(iii) any options granted or shares of Common Stock issued pursuant to existing
benefit plans of the Company.
 
     Prior to the Offering, the Morgan Stanley Shareholders, affiliates of MS &
Co., beneficially own in the aggregate 60.4% of the shares of Common Stock
outstanding. Immediately after the consummation of the Offering, the Morgan
Stanley Shareholders will own approximately 51.3% of the shares of Common Stock
outstanding and 38.9% of the outstanding voting Common Stock (approximately
50.1% and 37.7%, respectively of the outstanding Common Stock and outstanding
voting Common Stock if the Underwriters' over-allotment option is exercised in
full). The Morgan Stanley Shareholders have informed the Company that they
intend, upon the consummation of the Offering, to convert such number of their
shares of non-voting Common Stock so that, following such conversion, the Morgan
Stanley Shareholders will own, in the aggregate, 49% of the outstanding voting
Common Stock of the Company. In addition, affiliates of J.P. Morgan Securities
Inc., one of the Underwriters, own 696,726 shares of Class A Common Stock and
731,846 shares of Class C Common Stock. The Company has been informed that such
affiliates intend to convert all but 100 shares of Class A Common Stock into
Class C Common Stock immediately prior to the effectiveness of the Registration
Statement of which this Prospectus forms a part. Four of the Company's nine
directors are employees of MS & Co. MS & Co. acted as the placement agent for
the offering of the 12 1/4% Notes and 15% Notes and received compensation for
acting in such capacity. See "Certain Transactions."
 
     By virtue of such relationships described above, the provisions of Schedule
E ("Schedule E") to the Bylaws of the NASD apply to the Offering. Accordingly,
the public offering price can be no higher than that recommended by a "qualified
independent underwriter." In accordance with the requirements of Schedule E,
Lehman Brothers Inc. is assuming the responsibilities of acting as qualified
independent underwriter, and the initial public offering price of the shares of
Class A Common Stock offered hereby will not be higher than the
 
                                       75
<PAGE>   76
 
initial public offering price recommended by Lehman Brothers Inc. Lehman
Brothers Inc. also has participated in the preparation of the Registration
Statement of which this Prospectus is a part and has performed due diligence
with respect thereto.
 
     Pursuant to the requirements of Schedule E, the Underwriters will not
confirm sales of shares of Common Stock offered hereby to any accounts over
which they exercise discretionary authority without the prior written approval
of the transaction by the customer.
 
     At the request of the Company, the Underwriters have reserved 400,000
shares of the Class A Common Stock for sale at the initial public offering price
to employees of the Company and certain other individuals who have expressed an
interest in purchasing such shares. The number of shares available for sale to
the public will be reduced to the extent such individuals purchase such reserved
shares. Reserved shares purchased by such individuals will, except as restricted
by applicable securities laws, be available for resale following the Offering.
 
     Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock has been
determined by negotiations between the Company and the Underwriters in
accordance with the recommendations of Lehman Brothers Inc., the "qualified
independent underwriter," as required by Schedule E. Among the factors
considered in determining the initial public offering price were the sales,
earnings and certain other financial and operating information of the Company in
recent periods, the future prospects of the Company and its industry in general,
and certain ratios, market prices of securities and certain financial and
operating information of companies engaged in activities similar to those of the
Company and such other factors as may be deemed relevant. The initial public
offering price does not necessarily bear any relationship to the Company's
assets, book value, revenues or other established criteria of value, and should
not be considered indicative of the actual value of the Common Stock.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF PAGEMART WIRELESS, INC.:
 
     We have audited the accompanying consolidated balance sheets of PageMart
Wireless, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1994
and 1995, and the related consolidated statements of operations, stockholders'
equity (deficit) and cash flows for each of the three years in the period ended
December 31, 1995. 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 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 financial statements referred to above present fairly,
in all material respects, the financial position of PageMart Wireless, Inc. and
subsidiaries as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. GENERAL
 
     PageMart, Inc. ("PageMart") was incorporated as a Delaware corporation on
May 8, 1989, to provide wireless messaging products and services. In January
1995, PageMart effected a corporate reorganization pursuant to which PageMart
Nationwide, Inc., a Delaware corporation, became the holding company parent of
PageMart. In December 1995, the corporate name was changed from PageMart
Nationwide, Inc. to PageMart Wireless, Inc. ("Wireless"). Wireless and its
subsidiaries are referred to herein as the "Company." The consolidated financial
statements of the Company include the accounts of PageMart and PageMart PCS,
Inc. ("PageMart PCS"). PageMart PCS holds one of the NPCS Licenses (defined
herein) and certain other assets to be used in two-way wireless messaging. The
consolidated financial statements of PageMart include the accounts of PageMart
II, Inc., PageMart Operations, Inc., PageMart of California, Inc., PageMart of
Virginia, Inc. and PageMart International, Inc. Each of these companies is a
wholly-owned subsidiary of PageMart. PageMart II, Inc. and PageMart Operations,
Inc. hold certain Federal Communications Commission ("FCC") licenses. PageMart
International, Inc., which has had no significant operations to date, holds
certain investments in an international venture in Canada. Other than these
licenses and international investments, the subsidiaries of PageMart have no
significant assets or liabilities.
 
     The Company has incurred substantial losses from operations and negative
cash flows from operations since inception and is highly leveraged. Management
expects to continue to incur operating losses in 1996. These losses are driven
by the Company's investment in the growth of its subscriber base and continued
expansion into additional markets. The Company's business plan calls for
substantial growth in its subscriber base in order for the Company to achieve
operating profitability and positive cash flows from operations. There can be no
assurance that the Company will meet its business plan, achieve operating
profitability, or achieve positive cash flows from operations. If the Company
cannot achieve operating profitability, it may not be able to make the required
payments on existing or future obligations.
 
     The Company has made significant investments in Narrowband Personal
Communications Services ("NPCS") licenses through participation in auctions
conducted by the FCC. The Company plans to utilize these assets in connection
with two-way wireless messaging services. The Company's success in implementing
two-way services is dependent primarily upon market acceptance of proposed
two-way services and the ability of the Company to successfully develop and
construct a transmission network and market its two-way services. There can be
no assurance that two-way services offered will be accepted by the market or
that the Company will be successful in developing and constructing a
transmission network or marketing its two-way services.
 
     During 1993, the Company received net proceeds of approximately $17 million
from the issuance of Series C Preferred Stock and net proceeds of approximately
$71 million from the issuance of 12 1/4% Senior Discount Notes due 2003 and
common stock warrants (see Note 5). During 1994, the Company received net
proceeds of approximately $76.9 million from the issuance of common stock (the
"1994 Stock Offerings"). In conjunction with the 1994 Stock Offerings, each
outstanding share of preferred stock was converted into one share of common
stock (see Note 8).
 
     During 1995, the Company received net proceeds of approximately $100
million in connection with the issuance of 15% Senior Discount Notes due 2005
and non-voting common stock (see Note 5 and Note 8) and net proceeds of
approximately $24.5 million from the issuance of common stock (see Note 8).
Additionally, the Company entered into a revolving credit agreement with BT
Commercial Corporation, as Agent and Bankers Trust Company, as Issuing Bank,
which provides for a $50 million revolving line of credit (the "Revolving Credit
Agreement") (see Note 5).
 
     In management's opinion, the Company's current working capital combined
with borrowings expected to be available from the Revolving Credit Agreement
will be sufficient to support the planned growth for its one-way wireless
communications operations through 1996. As the Company begins implementation and

development of two-way services, the Company anticipates requiring additional
sources of capital to fund the construction and operation of a two-way messaging
network.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CONSOLIDATION
 
     The accompanying financial statements include the accounts of Wireless and
its wholly owned subsidiaries. All significant intercompany balances and
transactions have been eliminated.
 
CASH AND CASH EQUIVALENTS
 
     The Company includes as cash and cash equivalents cash on hand, cash in
banks and highly liquid investments with original maturities of three months or
less.
 
SHORT-TERM INVESTMENTS
 
     Short-term investments consist of investments in high-grade commercial
paper with original maturities of more than three months for which market value
approximates cost. The Company's short-term investments are made in reputable,
creditworthy companies and government issues and do not generate significant
credit risk to the Company.
 
INVENTORIES
 
     Inventories consist of pagers held for resale and are stated at the lower
of cost or market. Cost is determined by using the specific identification
method, which approximates the first-in, first-out method. The Company purchases
a majority of its pagers from Motorola, Inc.
 
RESTRICTED INVESTMENTS
 
     Restricted investments represent certificates of deposit in the amount of
$500,000 pledged as collateral on the Company's notes payable to a vendor.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost and depreciated using the
straight-line method for financial reporting purposes and accelerated methods
for tax reporting purposes over estimated useful lives ranging from three to
seven years. Depreciation expense totaled approximately $4,860,000, $7,824,000
and $12,683,000 for the years ended December 31, 1993, 1994 and 1995,
respectively. The Company purchases a majority of its network equipment from
Motorola, Inc. and Glenayre Technologies, Inc. Maintenance and repair costs are
charged to expense as incurred.
 
     Property and equipment consisted of the following (in thousands):

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
REVENUE RECOGNITION
 
     The Company recognizes equipment revenue immediately upon the shipment of
pagers adjusted by allowances for normal returns. Recurring revenue, including
revenue from airtime charges and fees for other services such as voicemail,
customized coverage options and toll-free numbers are recognized in the month in
which the service is provided. All expenses related to the sale of equipment are
recognized at the time of sale. Deferred revenue represents advance billings for
services not yet performed. Such revenue is deferred and recognized in the month
in which the service is provided. Patent licensing revenues are recognized on a
straight-line basis over the term of the related agreement (see Note 6). Patent
licensing revenues of $383,000 are included in recurring revenues in fiscal
1995.
 
USE OF ESTIMATES
 
     The preparation of 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 financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
ADVERTISING EXPENSES
 
     Advertising expenses are expensed as incurred.
 
EARNINGS PER SHARE
 
     Net loss per share amounts as reflected on the statements of operations are
based upon the weighted average number of common shares outstanding. The
weighted average number of common shares outstanding assumes that the preferred
shares were converted into common shares at January 1, 1993 (see Note 8). As
required by the Securities and Exchange Commission rules, all warrants, options
and shares issued during the year immediately preceding the initial public
offering are assumed to be outstanding for all periods presented. Shares
issuable upon the exercise of stock options and warrants granted before the year
immediately preceding the initial public offering were not included in the net
loss per share calculation as the effect from the exercise of those options
would be antidilutive.
 
RECLASSIFICATIONS
 
     Certain amounts in the prior years' consolidated financial statements have
been reclassified to conform with the current year presentation.
 
ACCOUNTING FOR LONG-LIVED ASSETS
 
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of" ("SFAS 121"). The Company will adopt SFAS
121 for the fiscal year ending December 31, 1996. SFAS 121 establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used and for long-lived assets and certain identifiable intangibles to be
disposed of. SFAS 121 requires that those assets to be held and used be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable through future cash flows.
SFAS 121 requires that those assets to be disposed of be reported at the lower
of the carrying amount or the fair value less cost to sell. Adoption of SFAS 121
is not expected to have a material effect on the financial statements of the
Company.

INTERIM FINANCIAL PRESENTATION
 
     The accompanying unaudited consolidated financial statements have been
prepared by the Company in accordance with generally accepted accounting
principles for interim financial information and substantially in the form
prescribed by the Securities and Exchange Commission in instructions to Form
10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring adjustments) considered necessary
for a fair presentation have been included. Operating results for the three
month period ended March 31, 1996 are not necessarily indicative of the results
that may be expected for the year ending December 31, 1996.
 
3. NARROWBAND PERSONAL COMMUNICATIONS SERVICES LICENSES
 
     During July and December 1994, the Company participated in auctions of NPCS
frequencies conducted by the FCC. As a result of the auctions, the Company was
awarded two nationwide NPCS licenses for a total purchase price of approximately
$133 million. Amortization of the NPCS licenses will commence when placed in
service. The NPCS licenses will be amortized over a period not to exceed 40
years. The Company intends to follow the provisions of Statement of Financial
Accounting Standards No. 34 "Capitalization of Interest Cost" with respect to
its NPCS licenses and the related construction of its two-way messaging network.
 
4. INVESTMENT IN UNCONSOLIDATED SUBSIDIARY
 
     Effective November 15, 1995, PageMart International, Inc. owns 200,000
shares of common stock of PageMart Canada Limited ("PageMart Canada") which
represents 20% of the ownership of PageMart Canada. The remaining 800,000 shares
(representing 80% of the ownership) is held by PageMart Canada Holding
Corporation ("Canada Holding"). Canada Holding is owned 50% (1,000,000 shares of
Class A Common Stock) by third-party Canadian investors unrelated to PageMart
and 50% (1,000,000 shares of Class B Common Stock) by PageMart International,
Inc. The common shares have identical economic rights. However, voting control
of Canada Holding is held by the Class A Common Stockholders as the Class A
shares have two votes per share. The Company accounts for its investments in
PageMart Canada and Canada Holding under the equity method. Such investments are
included in Other Assets in the Consolidated Balance Sheet.
 
     The agreement among stockholders contains provisions which restrict the
transfer of Canada Holding shares and PageMart Canada shares for periods ranging
from three to five years. During the two years following the third anniversary
of the transactions, the third-party Canadian investors may exchange the
1,000,000 Class A common shares they hold in Canada Holding for 714,286 shares
of voting common stock of Wireless, subject to certain U.S. and Canadian
ownership requirements. Wireless is ultimately responsible for effectuating the
exchange within the U.S. and Canadian ownership regulations. Such exchange may
be accelerated in the event Wireless enters into an agreement to be acquired.
After the third anniversary of the transactions, Wireless will have the right to
purchase the shares held by the third-party Canadian investors at their fair
market value provided regulatory ownership requirements permit such purchase.

     During the fourth quarter of 1993, the Company completed an offering in
which it issued $136.5 million principal amount (at maturity) of 12 1/4% Senior
Discount Notes due 2003 (the "12 1/4% Notes") with an initial accreted value of
$71.6 million together with warrants to purchase 627,900 shares of its common
stock for $3.26 per share. From and after May 1, 1999, interest on the 12 1/4%
Notes will be payable semiannually in cash at the rate of 12 1/4% per annum. The
12 1/4% Notes represent senior indebtedness of the Company and are redeemable at
the option of the Company, in whole or in part, at any time after November 1,
1998, at $136.5 million plus accrued interest. In addition, at any time prior to
November 1, 1996, up to 35% of the accreted value of the 12 1/4% Notes are
redeemable at the option of the Company with the proceeds of a Public Equity
Offering (as defined) at 111% of accreted value plus accrued and unpaid
interest, if any.
 
     In July 1994, the Company commenced an exchange offer pursuant to an
effective registration statement whereby all outstanding 12 1/4% Notes were

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In June 1995, the Company commenced an exchange offer pursuant to an
effective registration statement whereby all outstanding 15% Notes were
exchanged for the Company's 15% Senior Discount Exchange Notes due 2005.
 
     The 12 1/4% Notes and the 15% Notes carry certain restrictive covenants
that, among other things, limit the ability of the Company to incur
indebtedness, pay dividends, prepay subordinated indebtedness, repurchase
capital stock, create liens, sell assets, engage in mergers and consolidations,
and enter into transactions with any holder of 5% or more of any capital stock
of the Company or any of its affiliates. The Company is in compliance with all
such restrictive covenants.
 
     On May 11, 1995, the Company entered into the Revolving Credit Agreement
which provides for a $50 million revolving line of credit. As of December 31,
1995, there were no loans outstanding under the Revolving Credit Agreement. The
maximum amount available under the Revolving Credit Agreement at any time is
limited to a borrowing base amount equal to the lesser of (i) a specified
percentage of eligible accounts receivable and inventory owned by Wireless, and
(ii) an amount equal to the service contribution of the Company as defined in
the Revolving Credit Agreement for the immediately preceding three-month period
times 4.0 (or 4.5, at all times prior to December 31, 1995). The interest rate
applicable to loans under the Revolving Credit Agreement is, at the option of
Wireless, either at a prime rate plus 1 1/4% or a Eurodollar rate plus 2 1/2%.
Commitments under the Revolving Credit Agreement expire and all loans thereunder
will be due and payable on March 31, 1999.
 
     The Revolving Credit Agreement contains certain covenants that, among other
things, limit the ability of the Company to incur indebtedness, make capital
expenditures and investments, pay dividends, repurchase capital stock, engage in
transactions with affiliates, create liens, sell assets, or engage in mergers
and consolidations, and also requires the Company to maintain certain financial
ratios.
 
     The Revolving Credit Agreement is secured by all trade receivables and
inventory owned by Wireless from time to time and by all of the capital stock of
PageMart owned by Wireless. As of December 31, 1995, the maximum amount
available under the Revolving Credit Agreement was $28.2 million.

7. FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used by the Company in
estimating the fair value disclosures for its financial instruments. For cash

Sheets are equal to fair value. For debt, management estimated the fair value
based upon quoted market prices for publicly traded debt and based on the
appropriate interest rate at year-end for all other debt.

PREFERRED STOCK
 
     On August 5, 1994, in conjunction with the 1994 Stock Offerings and the

     During the third quarter of 1994, the Company issued an aggregate of
11,242,857 shares of common stock in the 1994 Stock Offerings at a purchase

     The Stockholders' Agreement provides that the parties thereto ("Holders")
shall collectively have the right to "demand" registrations at any time at least
six months after an initial public offering following which the common stock of
the Company is publicly traded. Pursuant to these "demand" rights, Holders of
common stock (the "Registrable Securities") may request in writing that the
Company file a registration statement under the Securities Act of 1933, as
amended (the "Securities Act"), covering the registration of a number of shares
equal to at least three million shares or a lesser number if such number
represents a majority of the Registrable Securities then outstanding.
 
     On March 20, 1995, the Company granted to a strategic partner warrants to
purchase a total of 206,748 shares of the Company's common stock at an exercise

     Under the provisions of the Plan, the Company may also issue stock to
employees. The stock vests over a period not to exceed forty-eight months.
Additional vesting occurs upon death or disability. Upon the termination of an
officer, the Company can repurchase the unvested stock at cost. Under the Plan,
the Company issued 300,000 shares to an officer during 1992, at $.326 per share.
All awards under the Plan have been made at a price at or above the estimated
fair value of the Company's common stock at the date of grant.
 
     In the second quarter of 1992, a non-employee consultant was granted
options to purchase 20,000 shares of stock at an exercise price of $.33 per
share. The options were exercised during 1995.
 
     In October 1995, the FASB issued Statement No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123"). The Company will adopt SFAS 123 for the
fiscal year ending December 31, 1996. SFAS 123 establishes financial accounting
and reporting standards for stock-based employee compensation plans and for
transactions in which an entity issues its equity instruments to acquire goods
or services from nonemployees. SFAS 123 recommends, but does not require, that
companies account for all stock-based transactions as compensatory at the fair
value of the equity instrument. However, since SFAS 123 does not require that
the accounting be adopted, it allows companies to continue to account for such
stock-based transactions under the provision of Accounting Principles Board
Opinion No. 25 (the Company's current method), and disclose what the pro forma
impact of adopting SFAS 123 would have been to net income and earnings per share
had the Company elected to adopt the recommended accounting. The Company
anticipates that it will not adopt the recommended accounting of SFAS 123, but
will disclose the pro forma impact in the footnotes to the financial statements.
 
10. FEDERAL INCOME TAXES
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income Taxes." SFAS
109 requires an asset and liability approach which requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of
events which have been recognized in the Company's financial statements. The
Company had approximately $104.7 million and $126.8 million of net operating
loss carryforwards for federal income tax purposes at

December 31, 1994 and 1995, respectively. The net operating loss carryforwards
will expire in the years 2004 through 2010 if not previously utilized. The
utilization of these carryforwards is subject to certain limitations. Of the net
operating loss carryforwards at December 31, 1995, management has estimated that
approximately $34.1 million is subject to an annual utilization limit of $4.8
million.
 
     In connection with the adoption of SFAS 109, the Company has recorded a
valuation reserve equal to its net deferred tax asset at each reporting period,
due to historical and anticipated future operating losses. Accordingly, the
adoption of SFAS 109 did not have an effect on the Company's financial position
or results of operations. Management will evaluate the appropriateness of the
reserve in the future based upon historical and operating results of the
Company.
 
     Deferred income taxes reflect the tax consequences on future years of
temporary differences between the tax basis of assets and liabilities and their
financial reporting basis and the potential benefits of certain tax
carryforwards. The significant deferred tax assets and liabilities, as
determined under the provisions of SFAS 109, and the change in those assets and
liabilities are as follows (in thousands):
