ITEM 1. BUSINESS
 
GENERAL
 
     Metrocall, Inc. ("Metrocall" or the "Company") is the fifth largest paging
company in the United States, based on 2,142,351 pagers in service at December
31, 1996, providing local, regional and nationwide paging and other wireless
messaging services. While the Company operates regional and nationwide paging
networks throughout the United States, the Company's selling efforts are
currently concentrated in 32 markets and five operating regions: (i) the
Northeast (Massachusetts through Delaware); (ii) the Mid-Atlantic (Maryland and
the Washington, D.C. metropolitan area); (iii) the Southeast (including
Virginia, the Carolinas, Georgia, Florida, Alabama, Louisiana, Mississippi, and
Tennessee); (iv) the Southwest and (primarily Texas); and (v) the West
(primarily California, Nevada and Arizona). Through the Metrocall Nationwide
Wireless Network ("Nationwide Network"), the Company provides service to over
1,000 U.S. cities representing the top 100 Standard Metropolitan Statistical
Areas ("SMSAs").
 
     Set forth below is a table showing the Company's subscribers by geographic
region and number of units in service as of December 31, 1994, 1995 and 1996.

---------------
(1)  Includes approximately 420,000 pagers in service acquired in the FirstPAGE
     and MetroPaging acquisitions.
 
(2)  Includes approximately 900,000 pagers in service acquired in the Parkway,
     Satellite Paging, Message Network and A+ Network acquisitions.
 
     From December 31, 1993 to December 31, 1996, the Company has increased its
base of pagers in service from less than 250,000 to more than 2.1 million. This
growth has been accomplished through a combination of internal growth and a
program of mergers and acquisitions. In July, August, and November 1996,
Metrocall completed the Parkway Paging, Inc. ("Parkway"), Satellite Paging,
Message Network and A+ Network, Inc. ("A+ Network") acquisitions, respectively.
As a result of these acquisitions, Metrocall added approximately 900,000
subscribers to its base of pagers in service. In addition to the acquisitions,
the Company's total pagers in service grew approximately 32% through internal
growth in 1996. During 1995, the Company's total pagers in service grew
approximately 25%, exclusively through internal growth. In August and November
1994, Metrocall completed the FirstPAGE and the MetroPaging acquisitions,
respectively. As a result of the 1994 acquisitions, Metrocall added
approximately 420,000 subscribers to its base of pagers in service, more than
doubling its total pagers in service during 1994 alone.
 
                                        1
<PAGE>   3
 
     The Company's long-term strategy is to continue to expand its business by
providing paging and other wireless communication services to an increasingly
broad base of subscribers throughout the United States, while increasing total
revenues and EBITDA and de-emphasizing that portion of the business which has
historically leased pagers. The Company is seeking to increase its base of
subscribers by expanding its operations in existing, contiguous and other
markets, through start-up operations and internal growth. The Company has
significantly expanded its geographic coverage and subscriber base through four
acquisitions in 1996. Furthermore, the Company has signed a definitive
acquisition agreement to acquire the assets of Page America Group, Inc. ("Page
America").
 
     The Company's growth and expansion into new markets, whether internal or
through acquisitions, require significant capital investment for the
installation of paging equipment and technical infrastructure. The Company
incurred significant expenditures throughout the first three quarters of 1996
while it completed the expansion and build-out of its nationwide network.
 
     The Company's focus is now on integrating the 1996 acquisitions and
increasing the utilization of its networks completed during 1996. As a result of
the completion of the Company's nationwide network and an emphasis on
distribution channels through which pagers are generally sold rather than
leased, capital expenditures are expect to be reduced in 1997. While the Company
currently has no outstanding commitments with the exception of the Page America
transaction, the Company will continue to evaluate strategic acquisition targets
in the future. Potential future acquisitions will be evaluated on significant
strategic opportunities such as geographic coverage and regulatory licenses and
other factors including overall valuation, consideration and availability of
financing.
 
     Metrocall's paging operations are subject to regulation by the FCC and
various state regulatory agencies. Metrocall was incorporated under the laws of
the State of Delaware in 1982. Its executive offices are located at 6677
Richmond Highway, Alexandria, Virginia 22306, and its telephone number is (703)
660-6677.
 
BUSINESS STRATEGY
 
     The primary elements of the Company's business strategy are described
below.
 
  Distribution Strategy
 
     The Company's distribution strategy is designed to increase revenues,
EBITDA and subscribers in markets which have an existing sales presence. This
strategy entails: (i) pursuit of small- and mid-sized accounts; (ii) greater
emphasis on value-added, more profitable service offerings; (iii) expansion of
distribution channels, focusing on the increased use of indirect sales channels;
(iv) maintenance of a low cost operating structure, and (v) selling rather than
leasing pagers.
 
     - Pursuit of small- and mid-sized accounts.  The Company has historically
       focused its direct selling efforts on small accounts (historically those
       with less than 25 units in service) in order to minimize its dependence
       on any single customer and because the Company believes that smaller
       accounts are generally more profitable than larger accounts. Given
       increased operating efficiencies, the Company has been able to
       economically justify the pursuit of larger accounts, offering volume
       discounts where competition warrants. This strategy should facilitate
       growth of the customer base while maintaining operating margins.
 
     - Emphasis on value-added service offerings.  The Company continually
       develops and introduces enhanced services to increase average monthly
       revenue per unit ("ARPU") and attract new subscribers. A key feature of
       most of these services is that they can be made available to existing
       subscribers without the need for new customer equipment. During 1996, the
       Company adjusted its sales force's commission structure to focus on
       monthly recurring revenue as opposed to unit placements and the sale of
       customer owned and maintained ("COAM") units, which is an incentive to
       sell additional enhanced paging services and reduces capital expenditures
       requirements.
 
     - Expansion of distribution channels.  Given the growing appeal of the
       paging product to consumers, Metrocall continues to expand its
       distribution channels to access as wide a range of potential
 
                                        2
<PAGE>   4
 
       subscribers as possible. Database marketing efforts have expanded as well
       as new initiatives involving strategic alliances, franchising, and
       multi-level marketing, all designed to ultimately lower distribution
       costs. These new channels have allowed the Company to access subscribers
       that would not typically be targeted by the direct sales force and
       ensures efficient utilization of technical capacity by maximizing the
       number of subscribers on the Company's network. The importance of these
       indirect channels in the Company's subscriber base is growing, comprising
       approximately 50% of the Company's subscriber base at December 31, 1996.
 
       The Company believes that as the appeal of the paging product to the
       consumer segment grows, retail and direct response distribution will
       become an increasingly important focus of its marketing strategy. The
       consumer segment is particularly attractive because these customers
       typically buy, rather than lease, pagers, allowing the Company to more
       quickly recover capital invested in inventory, and rarely require
       discounts on service rates (although discounts for one year lump sum
       payments are common). Through the acquisitions of Parkway, Satellite
       Paging, Message Network and A+ Network, the Company inherited over 80
       company-owned retail stores. These new outlets allow the Company
       continued access to the retail market place.
 
       With a renewed focus on both local and nationwide small business and
       consumer markets, the Company has begun entering into strategic
       partnerships with selected companies that have large customer bases such
       as long-distance providers and cable companies. This approach, which
       seeks to establish a mutually beneficial relationship for both parties,
       provides access to a market that is predisposed toward the Company's
       products and services. The Company expects these partnerships to become
       an increasingly important component of its distribution strategy in the
       future.
 
     - Maintenance of low cost operating structure.  The Company is able to
       compete effectively and price its services competitively due to its low
       cost operating structure and its efficient use of capital. Administrative
       functions are consolidated in a national operations center which handles
       all back-office functions including management information systems,
       billing and inventory management. Acquisitions closed during 1996 more
       than doubled the size of the Company. The timely integration of these
       transactions into the Company's existing back-office systems will provide
       increased economies of scale and operating leverage in future periods.
 
     - Sale versus lease.  The Company has focused virtually all of its new
       strategic initiatives on the sale rather than lease of paging units
       resulting in lower capital and debt requirements for unit growth. As the
       1996 acquisitions are integrated and operating margins begin to expand,
       the Company believes its focus on COAM delineation will provide
       significant progress toward the Company's ultimate objective of
       generating free cash flow.
 
  Integration Strategy
 
     The Company's integration strategy is based upon the belief that certain
functions are best performed and managed centrally and that others are best
managed on a decentralized basis. During 1996, the Company has directed
significant resources and management attention to the integration of the
Parkway, Satellite Paging, Message Network and A+ Network acquisitions.
 
     The Company's integration strategy is designed to consolidate the acquired
companies into Metrocall and create a homogenous company focused on the
corporate mission of growing revenue, EBITDA while expanding its base of
subscribers. In order to maximize operating efficiencies, certain functions must
be performed centrally. The Company also believes that in order to maximize
opportunity for acquisition of new customers and retention of existing
customers, certain functions must be performed on a decentralized basis.
 
     Functional areas the Company believes should be performed centrally are
accounting, finance, cash management, accounts payable, accounts receivable,
payroll, inventory, billing systems, information systems management, network
engineering, human resource and employee benefit management. Functional areas
that the Company believes should be managed in a decentralized environment in
order to better respond to customer and competitive demands are sales,
marketing, customer service and technical maintenance.
 
                                        3
<PAGE>   5
 
     During 1996 the Company directed significant resources toward integrating
and consolidating centralized functions of Parkway, Satellite, Message Network
and A+ Network properties. By year end, the Company had completely consolidated
and centralized all accounting and financial functions, human resources,
inventory and network engineering of Parkway, Satellite Paging and Message
Network. The process of consolidating these functions has begun for the A+
Network. Decentralized functions such as sales and customer service at A+
Network, Parkway Paging, Satellite Paging and Message Network adopted
Metrocall's operating practices and standards to form a fully integrated sales
and service organization. Both Parkway and A+ Network utilized the same billing
platform as the Company bringing significant synergies to the integration
effort. Subsequent to year end, Message Network's billing system was converted
into the Company's leaving only Satellite's billing system to be converted.
 
     The Company gained operating synergies through the consolidation of
duplicative functions and the elimination of job functions and people resources.
Vendor consolidation for purchases of services, materials and products have
resulted in savings through increased volume discounts and economies of scale.
 
  Technical Infrastructure and Broadcast Spectrum
 
     The Company believes that a major point of competitive differentiation is
the quality of its paging networks. The Company has developed a state-of-the-art
paging system deploying current technology which achieves optimal building
penetration, wide-area coverage and the ability to deliver new and enhanced
paging services. During 1996, the Company added more than 1,000 transmitter
sites to its paging networks though internal construction and acquisitions.
Through its 1996 acquisitions, the Company has also increased its total
available broadcast spectrum in the Northeast, Southeast and Southwest regions
of the United States. The Company has existing paging transmission equipment and
spectrum capacity sufficient to support anticipated future growth.
 
     The Company's exclusive 929.5125 MHz nationwide network provides signal
coverage on a common frequency in each of the top 100 SMSAs in the United
States. The network is operated through Company owned transmitters and provides
nationwide service coverage in approximately 1,000 cities. The Company incurred
significant expenditures throughout the first three quarters of 1996 while it
completed the expansion and build-out of this nationwide network. The network
allows the Company to provide subscribers with low cost, price competitive
nationwide paging service, and also provides the Company a platform from which
to enter new markets cost effectively by using the existing nationwide network
infrastructure to carry a local frequency during the start-up period. In this
way, the Company can place a local or regional frequency in a pre-existing
nationwide transmitter and thus begin service in a new market at low incremental
cost without delay. Customers in new markets opened in this way can be
economically serviced by the National Customer Operations Center until such time
as a local sales office is established.
 
     The Company has a second exclusive nationwide network which has been fully
constructed on the 929.1875 MHz frequency. Ownership of this second nationwide
frequency ensures the Company has the flexibility to expand its operations
without potential capacity constraints.
 
     Together, the Company has over 1,150 transmitters on its two nationwide
networks with capacity to serve over one million additional subscribers. Each of
the Company's nationwide networks is fully compatible with the Motorola
InFlexion technology designed for high speed transmission and signaling. The
Company has more than 2,750 transmitters sites operating on a local, regional
and nationwide basis.
 
NEW PRODUCTS AND SERVICES
 
     The Company differentiates itself from its competitors by offering its
customers a variety of value-added services packaged to reflect the specific
subscriber's business or personal needs. Value-added services are billed as an
enhancement to the basic service and tend to result in higher ARPU. Two of these
valued added services, "One Touch" and "Metrocall Nationwide," are currently
available.
 
     One Touch Service(TM).  In June of 1995, the Company introduced its "One
Touch" (sometimes referred to as a "virtual office") advanced messaging service.
Each One Touch subscriber is assigned a personal
 
                                        4
<PAGE>   6
 
"1-800" telephone number and voice mailbox for a monthly fee. Through one
telephone number, customers can have calls routed to a home, office or cellular
phone and enjoy voice messaging and fax storage and forwarding services, all
with instant notification of mailbox activity via their pager. One Touch
services are offered either separately or in individualized packages designed to
meet the needs of special markets or affinity groups. The Company will, in the
near future, bill customers on a per-transaction basis (e.g., per page for
faxes) where appropriate, which should serve to increase per unit revenues. The
Company also will, in the near future, offer long distance service connection as
part of the One Touch service options. All One Touch services are available to
new and existing customers. An existing subscriber who desires One Touch
services does not require new equipment.
 
     Metrocall Nationwide.  Through its Nationwide Network the Company is able
to offer low-priced nationwide paging services in approximately 1,000 cities in
the top 100 SMSAs. Coverage is currently available in heavily traveled areas in
each location (e.g., airports, central business districts) and can be expanded
by the Company as warranted by customer demand for regional and nationwide
service.
 
     PCS Strategy.  During 1994, the FCC auctioned 1,237.5 KHz of narrowband
personal communication services ("PCS"') spectrum. The Company believes this
spectrum will allow paging operators to offer a broad array of new products and
services which heretofore were impossible to offer given the limited spectrum
allocated to traditional paging. These products include voice pagers, high speed
alphanumeric pagers and pagers which will allow subscribers to acknowledge the
receipt of messages. Several PCS systems are currently operational. The Company
elected not to participate in the spectrum auctions because the Company believes
that there will be ample PCS spectrum available which it can use to resell PCS
services to its existing customers. For example, the Company, through its
acquisition of A+ Network, has a minority ownership interest in CONXUS (formerly
PCS Development Corporation), a nationwide narrowband PCS license holder, and
has signed a memorandum of understanding to act as a co-developer of technology,
co-carrier of signal and distributor of services. The Company's affiliation with
CONXUS should enable it to offer its subscribers narrowband PCS services without
the licensing or capital cost associated with the construction of a narrowband
PCS network. The Company is pursuing similar relationships with other PCS
developers and operators. The Company believes that the current generation of
narrowband PCS product offerings are untested and subject to speculation and
uncertainty regarding competitive performance and financial viability. The
Company believes that until such performance and viability measures have been
proven, it will only offer such PCS services on a resale basis electing not to
incur the capital investment in equipment and broadcast spectrum.
 
PAGING OPERATIONS
 
     Subscribers and Services.  The Company currently provides four basic types
of paging services: (i) digital display pagers, which permit a subscriber to
receive a telephone number or other numeric coded information and to store
several such numeric messages that the customer can recall when desired; (ii)
alphanumeric display pagers, which allow the subscriber to receive and store
text messages; (iii) tone-only pagers, which notify the subscriber that a call
has been received by vibrating or emitting a beeping sound; and (iv)
tone-plus-voice pagers, which emit a beeping sound followed by a brief voice
message. The Company provides digital display, alphanumeric display and
tone-only service in all its markets, and provides tone-plus-voice service in a
few markets. Digital display paging service, which was introduced by the paging
industry over 10 years ago, has in recent years grown at a faster rate than
tone-only or tone-plus-voice service. A substantial majority of the Company's
pagers in service at December 31, 1996 were digital display pagers.
 
     Alphanumeric display service, which was introduced in the mid-1980s, has
grown at increasing rates as users and dispatch centers overcome technical and
operational obstacles to data input. For example, the Company now markets, under
its service mark "Notesender," a computer program designed for use in
transmitting alphanumeric messages from personal computers to pagers.
Alphanumeric paging access is also available via the Company's internet website,
www.metrocall.com, where any internet user can access our on-line alphanumeric
paging software. The Company also provides enhancements and ancillary services
such as

<PAGE>   7
 
personalized automated answering services, message protection, annual loss
protection and maintenance service on equipment. Personalized automated
answering services allow the subscriber to record a message that greets callers
who reach the subscriber's voice mailbox. Message protection allows a subscriber
to retrieve any calls that come in during the period when the subscriber was
beyond the reach of the Company's radio transmitters. Annual loss protection
allows subscribers who lease pagers to limit their costs of replacement upon
loss or destruction of the pager. Maintenance services are offered to
subscribers who own their own pagers.
 
     The Company's subscribers either lease or buy their pagers and purchase
either local, regional, multi-regional or nationwide service. Contracts with
large unit volume subscribers are typically for two to three year terms, while
contracts with smaller volume subscribers generally have one year terms with
annual renewals. The Company receives additional revenue for enhanced services
such as voice mail, personalized greetings and One Touch service. Volume
discounts on lease costs and service fees are typically offered to large unit
volume subscribers. In some instances, the Company's subscribers are resellers
that purchase services at substantially discounted rates, but are responsible
for marketing, billing and collection and related costs with respect to their
customers.
 
     The following table sets forth as of December 31, 1994, 1995 and 1996 the
respective numbers and percentages of pagers that are (i) serviced and owned by
the Company, (ii) serviced by the Company and owned by subscribers, (iii)
serviced by the Company and owned by subscribers sold through Company-owned
retail stores, (iv) serviced by the Company through resellers and owned by the
resellers or their subscribers, (v) serviced by the Company through other paging
carriers and owned by the carrier or their subscribers and (vi) serviced by the
Company and owned by subscribers who acquire equipment and service through
retailers.

     Sales and Marketing.  Subscribers who use paging services have
traditionally included small business operators and employees, professionals,
medical personnel, sales and service providers, construction and tradespeople,
and real estate brokers and developers. However, paging's appeal to the mass
market is growing, and the service is increasingly being adopted by individuals
for private, nonbusiness uses such as communicating with family members and
friends.
 
     While the Company historically has relied on its direct sales force to
obtain paging customers, it has implemented a strategy to capitalize on the
growing mass market appeal of paging products. This sales and marketing strategy
incorporates a multi-tiered distribution system that utilizes the following
distribution channels to access different market segments: (i) the Company's own
direct sales staff that concentrates on business accounts; (ii) database
telemarketing conducted by Company-employed professional sales staff
 
                                        6
<PAGE>   8
 
which utilizes computerized lead management and professional telemarketing
techniques to identify primarily small businesses and professionals as potential
subscribers; (iii) Company-owned retail stores, designed to sell higher ARPU
products and services to the consumer market; (iv) resellers, who purchase bulk
paging services and resell them to their own subscribers generally on a private
label basis; (v) retail outlets that sell pagers to the emerging consumer
market; (vi) independent dealers, representatives and agents, who use their own
sales forces to sell Metrocall paging equipment and services to their
established customer bases; (vii) strategic alliances, who market the Company's
products and services to established customer bases; and (viii) affiliates, who
offer expanded coverage options to their customers utilizing a Company-owned
frequency. As of December 31, 1996, the Company, through its 130 sales and
administrative offices, employed a sales force of 870 sales representatives,
including the Company's direct sales staff, telemarketing professionals and
sales representatives who call on retailers and resellers. The Company's
distribution channels are described briefly below.
 
  Direct Distribution Channels
 
     - Direct Sales.  Direct sales personnel sell primarily to businesses,
       placing special emphasis on key accounts, which are accounts that are of
       strategic importance to the Company. The businesses targeted by the
       Company's direct sales personnel are generally those that have highly
       mobile employees or employees with multiple work locations. Examples
       include hospitals, sales and service organizations, specialty trades,
       transportation, construction and manufacturing companies and government
       agencies. Direct sales personnel are compensated based on a percentage of
       sales contract value (plus certain quota incentives), reduced by any
       cancellations within the first 120 days of a contract. As previously
       discussed, sales compensation plans are designed to motivate direct sales
       personnel to increase sales of higher revenue products, such as
       nationwide service, alphanumeric service, voice mail, One Touch and other
       value-added services.
 
     - Database Telemarketing.  The Company's internal, professionally-trained
       staff uses computerized lead management and telemarketing techniques
       combined with the Company's proprietary lead screening and development
       protocol to generate sales. Using acquired lists to focus their effort,
       the internal staff targets groups of consumers and small businesses who
       have a propensity to use paging services but are either in a region where
       the Company does not have a direct sales effort or are not reached by
       other distribution channels. Telemarketing salespeople are compensated on
       a salary plus commission basis. The cost to add a new subscriber through
       this channel is lower than the cost through the direct sales channel.
 
     - Company-Owned Retail Stores.  Through the transactions with Parkway,
       Satellite Paging, Message Network and A+ Network, the Company acquired
       over 80 Company-owned retail outlets. These outlets are designed to sell
       higher ARPU services to the consumer market segment directly while
       providing a point of presence for the Company to enhance its brand
       recognition. These retail outlets take a variety of forms such as,
       in-line mall stores, kiosks, mall carts, retail merchandising units and
       strip center locations. Product offerings sold to consumers at these
       locations are paging, messaging, cellular, long distance, PCS and related
       accessories. Many of these locations function as customer service and
       payment centers in addition to offices for direct sales representatives.
 
  Indirect Distribution Channels
 
     - Resellers.  Resellers buy bulk paging services from the Company for
       resale to their own business clients and individual customers. The
       Company issues one monthly bill to each reseller who is responsible for
       marketing, billing and collection, and equipment maintenance. As a result
       of emphasizing this channel, the Company is able to achieve high network
       utilization at low incremental cost. The Company does not lease pagers to
       resellers.
 
     - Retail Outlets.  The Company sells pagers on a wholesale basis to retail
       outlets such as office supply, electronics and general merchandise chains
       for resale to consumers. These outlets are selected based on factors such
       as the number of stores in a region and the extent of their advertising.
       The outlets sell the
 
                                        7
<PAGE>   9
 
       pager itself and provide limited customer service to the consumer. The
       Company provides sales incentives and advertising support, and emphasizes
       training of sales personnel to enhance the retail outlet's effectiveness
       and to ensure that the customer is well educated regarding the product.
       The Company does not lease pagers to retailers. The Company believes that
       as consumer awareness of the product grows, retailers will become an
       increasingly important distribution channel.
 
     - Independent Dealers, Representatives and Agents.  The Company contracts
       with independent dealers, representatives and agents, including such
       outlets as small cellular phone dealers or independent specialty
       electronics stores. The Company typically uses dealers to reach specific
       consumer niches (e.g., ethnic or non-English speaking communities) and
       small businesses that are more efficiently accessed through this channel
       than through other distribution channels. In addition to selling the
       Company's pagers, independent dealers assist the subscriber in choosing a
       service plan and collect the initial payments. Independent dealers are
       paid commissions for their placement of customers with the Company.
 
     - Strategic Partners.  The Company has entered into contractual agreements
       with several selected national distribution partners who sell or resell
       Metrocall's paging services to their existing and future customer
       constituency. The Company supplies many of these partners with turnkey
       solutions, custom branded, for network services, products, customer
       services, billing, collections and fulfillment. The Company's strategy is
       to provide these value added services to enhance the business
       relationship and margin opportunities for both parties. Alliances with
       companies in the long distance, local exchange, cable, retail, direct
       response and multi-level marketing businesses have been engaged. The
       Company believes that these programs will help deliver paging services to
       market segments that our other distribution channels can not cost
       effectively reach.
 
     - Affiliates.  Through the merger with A+ Network, the Company now has a
       network of over one hundred paging carriers or affiliates that resell
       services on the 152.480 MHz private carrier paging frequency. The
       affiliates are independent owners of paging systems operating on this
       frequency in various markets throughout the nation who sell expanded
       coverage to their customers by utilizing the Company's infrastructure
       that links these independent networks to provide wide area and nationwide
       paging on a single channel. The Company provides expanded coverage
       options for approximately 130,000 subscribers throughout the nation
       through its affiliate network.
 
     The following table sets forth information regarding numbers of pagers in
service by distribution channel at December 31, 1994, 1995 and 1996.

     Centralized Organizational Structure.  In order to minimize its cost
structure, the Company centralizes operating functions where possible, utilizes
common billing and subscriber management systems throughout its markets. The
Company's centralized operating structure focuses regional management on sales
and distribution by transferring technical and back-office responsibilities to a
central location.
 
     The Company's administrative and back-office functions are located in a
single national operations center in Alexandria, Virginia. These functions
include all accounting, management information systems, inventory
 
                                        8
<PAGE>   10
 
and order fulfillment. As discussed earlier, the Company is in the process of
integrating its 1996 acquisitions into this structure.
 
     The Company also maintains a centralized National Customer Operations
Center. The Company's National Customer Operations Center handles customer
inquiries from existing and potential customers and supports the Company's
strategic distribution initiatives. The National Customer Operations Center is
staffed with approximately 150 employees and is open six days per week (with
emergency service provided seven days a week, 24 hours a day) with a toll-free
access number. In addition to responding to local customer service inquiries,
the National Customer Operations Center is a critical factor in marketing and
servicing the Nationwide Network to all markets in the United States. Efforts
are made to satisfy customers on initial inquiry to avoid repeat calls, thereby
increasing customer satisfaction and decreasing costs. The Company employs
state-of-the-art call management equipment (such as an automated call
distribution system) to provide quality customer service. The Company tracks
both productivity and quality of performance of its customer service
representatives.
 
     The Company also focuses on the allocation of administrative costs over a
greater number of units in service. While the Company expects revenue from units
in service to grow through internal growth, geographic expansion and its recent
acquisitions, the Company's administrative costs are expected to grow at a much
lower rate.
 
     Network and Equipment.  The Company has developed a state-of-the-art paging
system deploying current technology which achieves optimal building penetration,
wide-area coverage and the ability to deliver new and enhanced paging services.
This existing paging transmission equipment has significant capacity to support
future growth.
 
     The Company's paging services are initiated when telephone calls are placed
to the Company's paging terminals. These state-of-the-art terminals, which the
Company maintains within its service areas, have a modular design that allows
significant future expansion by adding or replacing modules rather than
replacing the entire terminal. The Company's paging terminals direct pages to
the Company's primary satellite, which signals terrestrial network transmitters
providing coverage throughout the service area.
 
     The Company operates a series of regional operating systems or networks
consisting of primary networks servicing the states of Arizona, California and
Nevada, and the area from Boston to the Virginia/North Carolina border. The
Company also has two exclusive licenses issued by the FCC for the same channel
in each of the largest 100 SMSAs and began operations of the Nationwide Network
on the channel in November 1993. The Company is also capable of providing local
paging in each market serviced by the Nationwide Network by using nationwide
transmitters to carry local messages. Services provided through the Nationwide
Network are marketed to subscribers directly through the Metrocall sales force
and indirectly through retailers and resellers.
 
     The Company does not manufacture any of the pagers or related transmitting
and computerized paging terminal equipment used in the Company's paging
operations. The equipment used in the Company's paging operations is available
for purchase from multiple sources, and the Company anticipates that equipment
and pagers will continue to be available to the Company in the foreseeable
future, consistent with normal manufacturing and delivery lead times. Because of
the high degree of compatibility among different models of pagers, transmitters,
computers and other paging equipment, the Company is able to design, supply and
operate its systems without being dependent upon any single source of such
equipment. The Company continually evaluates new developments in paging
technology in connection with the design and enhancement of its paging systems
and selection of products to be offered to subscribers.
 
     The Company achieves cost savings by purchasing pagers for a volume
discount from a limited number of companies, including Motorola, Inc.
("Motorola"), from which the Company currently purchases most of its pagers, and
NEC America, Inc. The Company purchases its transmitters and paging terminals
from Motorola and Glenayre Electronics, Incorporated.

PAGING INDUSTRY OVERVIEW
 
     Industry sources estimate that there were approximately 43.0 million pagers
in service in the United States at the end of 1996. Industry sources also
indicate that in recent years the number of pagers in service in the United
States has been growing at annual rates in excess of 20% per year and predict
that the number of pagers in service will continue to grow at compound annual
growth rates of approximately 15% through the year 2000. Factors that have been
described as contributing to this growth include (i) declining costs of service,
(ii) increasing consumer awareness of the benefits of mobile communications,
(iii) introduction of new or enhanced paging equipment and services, and (iv)
expanding channels of distribution.
 
     Although the United States paging industry has over 600 licensed paging
companies, the Company estimates that the ten largest paging companies,
including Metrocall, currently serve approximately 80% of the total paging
subscribers in the United States. These paging companies are facilities-based,
Commercial Mobile Radio Service ("CMRS") providers, previously classified as
either Radio Common Carrier ("RCC") or Private Carrier Paging ("PCP") operators,
servicing over 100,000 subscribers each in multiple markets and regions.
 
     The Company believes that future developments in the paging and wireless
communications industry will include (i) technological improvements that permit
increased service and applications to a wider market on a cost-effective basis,
(ii) consolidation of smaller, single-market operators and larger, multi-market
paging companies, and (iii) increased numbers of pagers in service, as a result
of general expansion into consumer and retail markets. Recent technological
developments in the paging industry include new paging services such as
"confirmation" or "response" paging that have the ability to send a message back
to the paging system that confirms that the paging message has been received,
digitized voice paging, two-way paging and notebook and sub-notebook computer
wireless data applications. Narrowband PCS may offer the ability to provide some
of these services on an expanded basis. While these services have been proven
technologically feasible, the economic viability has not been tested based on
the cost of licenses and capital infrastructure requirements.
 
PAGING TECHNOLOGY
 
     Paging is a method of one-way wireless communications that uses an assigned
radio frequency to contact a paging subscriber anywhere in a service area. A
subscriber carries a pager that receives messages by the broadcast of a one-way
radio signal. To contact a subscriber, a message is usually sent by placing a
telephone call to the subscriber's designated telephone number. The telephone
call is received by an electronic paging switch which then generates a signal
that is sent to radio transmitters in the service area. Depending upon the
topography of the service area, the operating radius of a radio transmitter
typically ranges from three to 20 miles. The transmitters send a signal that is
received by the pager carried by the subscriber and is delivered as a tone,
vibration, numeric or alphanumeric message. A tone-only pager notifies the
subscriber that a call has been received by emitting a beeping sound or
vibration. In the case of tone-plus-voice service, the subscriber's pager emits
a beeping sound followed by a brief voice message. Depending upon the type of
pager in use, the subscriber may receive a message that is displayed on the
pager or a subscriber may call his or her home, office or telemessaging service
to receive the message. A digital display pager permits a caller to transmit to
the subscriber a numeric message that may consist of a telephone number, an
account number or coded information. A digital display pager has the memory
capability to store several numeric messages that can be recalled by the
subscriber when desired. Alphanumeric display paging service allows subscribers
to receive and store messages consisting of both numbers and text.
 
     Metrocall believes that paging is the most cost-effective and reliable
means of conveying a variety of information rapidly over a wide geographic area
either directly to a person traveling or to various fixed locations. Because it
is a one-way communication tool, paging is an inherently lower cost way to
communicate than two-way communication methods. For example, pagers and air time
required to transmit an average message cost less than equipment and air time
for cellular and other wireless PCS telephones. Furthermore, pagers operate for
longer periods due to superior battery life, often exceeding one month on a
single AAA battery. Paging subscribers generally pay a flat monthly service fee,
which covers a certain number of messages sent to the subscriber. In addition,
pagers are unobtrusive, portable and historically have not become
 
                                       10
<PAGE>   12
 
obsolete even in the face of substantial technological advances in the
communications industry. Growth in the number of cellular telephone customers is
increasingly viewed as a complement to wireless messaging. Many cellular
telephone customers use pagers in conjunction with their telephones to screen
incoming calls and minimize battery use and cellular usage charges.
 
COMPETITION
 
     The Company experiences competition from one or more paging operators in
all of the regions in which it operates. Some of the Company's competitors have
greater financial resources than the Company. Since 1988, the Company has
competed with Paging Network, Inc. ("PageNet"), the world's largest provider of
paging services, in all of the Company's major markets. The Company believes
that competition for subscribers is based on price, geographic coverage and
quality of service. Metrocall believes that it compares favorably with its
competitors on these bases.
 
     With the introduction of the Nationwide Network, the Company's principal
competitors for national accounts are MobileMedia Communications, Inc. (using
the trade name MobileComm), SkyTel Corporation ("SkyTel"), a subsidiary of MTEL,
Inc., PageMart, Inc. ("PageMart"), and PageNet. In addition to MobileComm,
SkyTel, PageMart and PageNet, the Company is aware of other paging companies
that offer, or intend to offer, nationwide paging services to their subscribers.
 
     In 1994, the FCC began auctioning licenses for new PCS. PCS involves a
network of small, low-powered transceivers placed throughout a neighborhood,
business complex, community or metropolitan area to provide customers with
mobile voice and data communications. There are two types of PCS, narrowband and
broadband. Narrowband PCS is expected to provide enhanced or advanced paging and
messaging capabilities, such as "acknowledgment paging" or "talk-back" paging.
Broadband PCS is expected to provide new types of communications devices that
will include multi-functional portable phones and imaging devices. PCS providers
may compete directly and indirectly with the Company.
 
     Future technological developments in the wireless telecommunications
industry, such as PCS, and enhancements of current technology could create new
products and services which might compete with the paging services currently
offered by Metrocall. There can be no assurance that Metrocall would not be
adversely affected by such technological change.
 
REGULATION
 
     Federal.  Metrocall's paging operations are subject to regulation by the
FCC under the Communications Act of 1934, as amended (the "Communications Act").
The Communications Act requires that the Company obtain licenses from the FCC to
use radio frequencies to conduct its paging operations within specified
geographic areas. In addition to authorizing the use of the radio frequencies,
FCC licenses awarded to the Company set forth the technical parameters, such as
maximum power and tower height, under which the Company is permitted to use
those frequencies.
 
     The Company has historically provided paging services as both an RCC
operator and PCP operator. Traditionally, RCC frequencies were assigned on an
exclusive basis to a single licensee in a service area; RCCs were subject to
regulation by the states as well as by the FCC and were permitted (indeed,
required) to provide service to anyone requesting such service. PCP frequencies
were assigned on a shared basis (i.e., multiple parties in the same area could
apply for and obtain a license to use the same frequency); there were
restrictions on eligibility of PCP customers; and the states were preempted from
regulating PCP entry, rates, operation, terms of service, etc.
 
     In 1993, the FCC permitted PCPs to provide service to individuals, rather
than only for business purposes. Additionally, in November of 1993, the FCC
adopted new rules to provide "channel exclusivity" to PCP operators operating on
certain 929 MHz frequencies, provided the licensee meets certain qualifications.
The Company has obtained nationwide exclusivity on two of its 929 MHz
frequencies (one used for the Nationwide Network; the other obtained in the
First PAGE acquisition). Under the FCC's current rules, no other entity may
apply anywhere in the U.S. on either of the Company's frequencies. Any PCP
licenses other
 
                                       11
<PAGE>   13
 
than the Company's that were previously granted by the FCC may continue
operating on those frequencies, but those other licensees will not be allowed to
expand their paging services beyond their existing coverage areas. Additionally,
on other 929 MHz frequencies, the Company has local exclusivity in the Chicago,
IL area, and for regional exclusivity in the Northeast, Mid-Atlantic, and
(through the A+ Network merger) Southeast areas of the United States.
 
     PCP channels below 900 MHz are still allocated on a shared basis. The
Company obtained a 152.480 MHz shared frequency network through its merger with
A+ Network. Applications for those frequencies are first processed through a
frequency coordinator, which attempts to minimize overcrowding on a given
frequency. The coordinator then files the applications with the FCC, which
processes them on a first-come, first-served basis. So long as a given PCP
frequency is not congested with multiple licensees, the subscriber would not
perceive any differences between shared PCP services and exclusive paging
services. In most areas of the country where the Company holds shared PCP
licenses, the Company is the only paging operator, or one of only a few
operators, licensed on its particular frequency in that area.
 
     In August of 1993, as part of its Omnibus Budget Reconciliation Act (the
"Budget Act"), Congress amended the Communications Act to, inter alia, replace
the prior common carrier and private radio definitions with two newly defined
categories of mobile radio services: (1) CMRS (commercial mobile radio service)
and (2) PMRS (private mobile radio service). The CMRS definition essentially
supplants the prior RCC definition. The FCC has determined that PCP and RCC
paging services are classified as CMRS. The FCC has adopted technical,
operational and licensing rules for CMRS, which became effective on January 2,
1995, and which became applicable to "grandfathered" PCP operators (including
the Company) on August 10, 1996.
 
     Pursuant to authority granted by the Budget Act, the FCC has "forborne"
from enforcing against all CMRS licensees the following common carrier
regulations under Title II of the Communications Act: any interstate tariff
requirements, including regulation of CMRS rates and practices; the collection
of intercarrier contracts; certification concerning interlocking directorates;
and FCC approval relating to market entry and exit. Additionally, the Budget Act
preempted state authority over CMRS entry and regulation.
 
     Historically, paging licenses have been issued for terms of either 10 years
(for RCCs) or 5 years (for PCPs); all paging licenses issued in the future will
be for 10-year terms. Renewal applications must be approved by the FCC. The
Company's current licenses have expiration dates ranging from 1997 to 2007. In
the past, FCC renewal applications have been routinely granted. Although there
can be no assurance that any future applications filed by the Company will be
approved or acted upon in a timely manner by the FCC, based on its experience to
date, the Company knows of no reason to believe such applications would not be
approved or granted.
 
     The Communications Act also requires prior FCC approval for acquisitions by
the Company of radio licenses held by other companies, as well as transfers of
controlling interests of any entities that hold radio licenses. Although there
can be no assurance that any such future applications filed by the Company will
be approved or acted upon in a timely manner by the FCC, based on its experience
to date, the Company knows of no reason to believe such applications would not
be approved or granted.
 
     The Communications Act places limitations on foreign ownership of CMRS
licenses. These foreign ownership restrictions limit the percentage of Company
stock that may be owned or voted, directly or indirectly, by aliens or their
representatives, foreign governments or their representatives, or foreign
corporations. The Company's Certificate of Incorporation permits the redemption
of the Common Stock from stockholders where necessary to protect the Company's
compliance with there requirements.
 
     The FCC has authority to restrict the operation of licensed radio
facilities or to revoke or modify such licenses. The FCC may adopt changes to
its radio licensing rules at any time, and may impose fines for violations of
its rules. Under certain circumstances, the Company's license applications may
be deemed "mutually exclusive" with those of other paging companies, in which
case, the FCC would select between the mutually exclusive applicants. The FCC
previously used lottery procedures to select between mutually exclusive
applications. Pursuant to authority granted by the Budget Act, the FCC will in
the future select
 
                                       12
<PAGE>   14
 
between mutually exclusive CMRS paging applications through competitive bidding
procedures (i.e., auctions).
 
     Paging licenses have traditionally been issued on a site-specific basis. On
February 19, 1997, the FCC adopted rules to issue most paging licenses for
large, FCC-defined service areas. Although the rules are subject to a pending
appeal and potential petitions for reconsideration, if they become "final", the
following changes will occur. Licenses for 929 MHz PCP and 931 MHz RCC
frequencies will be issued for larger geographic areas than licenses for RCC
frequencies in lower frequency bands (which will be licensed in "Economic Areas"
or "EAs"). Shared PCP frequencies will continue to be allocated on a shared
basis and licensed in accordance with existing, site-specific procedures;
however, the FCC is considering changes to the application and licensing rules
for these frequencies. Mutually exclusive geographic area applications for all
RCC frequencies and exclusive 929 MHz PCP frequencies will be awarded through an
auction process. The FCC has stated that it will dismiss all pending mutually
exclusive applications for these frequencies , as well as all applications filed
after July 31, 1996 regardless of mutual exclusivity . A filing "freeze" is in
effect for the non-nationwide, exclusive paging frequencies pending commencement
of the auctions. The FCC has not yet announced when paging auctions will begin,
or the order in which it will make the various frequencies and geographic areas
available for bidding. Incumbent licensees will be able to trade in their
existing licenses for a single "wide-area" license based upon their current
coverage; incumbents will be entitled to interference protection from the
auction winners and will be able to modify their facilities within that area,
but they will not be permitted to expand their existing coverage.
 
     Because auctions are new to paging, the Company cannot predict their impact
on its paging business. At least initially, competitive bidding may increase the
Company's costs of obtaining licenses. The FCC's wide-area licensing and auction
rules may also serve as entry barriers to new participants in the paging
industry. In any service area where the Company is the successful bidder, or
where it trades in its licenses for "wide-area" licenses, the Company will save
on the application costs associated with modifying and adding facilities within
its service areas, and no other entity will be able to apply for the Company's
frequencies within those areas, Conversely, in geographic areas where the
Company is not the high bidder, its ability to expand its service territories in
those geographic areas will be curtailed. The Company's nationwide frequencies
will not be subject to competitive bidding, although the FCC is considering
imposing additional "build-out" requirements on the Company and other nationwide
licensees.
 
     The FCC could change its rules or policies in a manner that could have a
material adverse effect on the Company's business. Such actions could affect the
scope and manner of the Company's services, or could lead to increased
competition in the paging industry. Other changes may have a positive impact for
the Company. For example, under the Telecommunications Act of 1996 (the "Telecom
Act") and the FCC's interpreting orders, local exchange carriers ("LECs") are
prohibited from charging paging carriers for the "transport and termination" of
LEC-originated local calls. This could lead to substantial cost savings for the
Company. Moreover, under the Telecom Act and the FCC's rules, paging services
are entitled to compensation from any telecommunications carrier that terminates
a call on a paging network. This could lead to additional revenues for paging
carriers. The Company cannot predict the final outcome of any FCC proceeding or
the possible impact of future FCC proceedings.
 
     State.  The Budget Act preempts all state and local rate and entry
regulation of all CMRS operators. The Budget Act became effective August 10,
1994. Entry regulations typically refer to the process whereby an RCC operator
must apply to the state to obtain a certificate to provide service in that
state. Rate regulation typically refers to the requirement that RCC operators
file a tariff describing the Company's rates, terms and conditions by which it
provides paging services. Apart from rate and entry regulations, some states may
continue to regulate other aspects of the Company's business in the form of
zoning regulations, or "health and safety" measures. The Budget Act does not
preempt state authority to regulate such matters. Although there can be no
assurances given with respect to future state regulatory approvals, based on its
experience to date, the Company knows of no reason to believe such approvals
would not be granted. The Telecom Act requires that state and local zoning
regulations shall not unreasonably discriminate among providers of "functionally
equivalent" wireless services, and shall not have the effect of prohibiting the
provision of personal wireless services. The Telecom Act provides for expedited
judicial review of state and local zoning decisions.
 
                                       13
<PAGE>   15
 
Additionally, state and local governments may not regulate the placement,
construction and modification of personal wireless service facilities on the
basis of the environmental effects of radio frequency emissions, if the
facilities comply with the FCC's requirements.
 
     Pursuant to the Budget Act's preemption provisions, in August 1994, eight
states petitioned the FCC to retain rate regulation authority over intrastate
CMRS operators. The FCC denied those petitions, and all appeals before the FCC
have been exhausted. One state, Connecticut, filed an appeal of the FCC's order
denying its petition with the U.S. Court of Appeals for the Second Circuit; the
Second Circuit affirmed the FCC's decision in early 1996.
 
     Legislative Changes.  From time to time, federal and state legislators
propose legislation that could affect the Company's business, either
beneficially or adversely. For example, the Budget Act requires the FCC to hold
public auctions to award new PCS licenses throughout the United States. While
PCS services do not pose an imminent threat to the Company's business, such
regulatory and legislative actions may increase competition and affect the
Company's cost of operations. The recently-enacted Telecom Act will also have an
impact on the paging industry; the Company expects that that impact will be
mostly positive. For example, the Telecom Act imposes a duty on all
telecommunications carriers to provide interconnection to other carriers, and
requires LECs to, among other things, establish reciprocal compensation
arrangements for the transport and termination of calls, provide other
telecommunications carriers access to the network elements on an unbundled basis
on reasonable and non-discriminatory rates, terms and conditions. The Telecom
Act also requires the FCC to appoint an impartial entity to administer
telecommunications numbering and to make numbers available on an equitable
basis. Additionally, as previously indicated, the Telecom Act restricts state
and local authority with regard to zoning and environmental regulation of
telecommunications operators. Other provisions of the Telecom Act, however, may
provide for increased competition to the Company (for example, the provisions
allowing the FCC to forbear from applying regulations and provisions of the
Communications Act to any class of carriers, not only to CMRS, and the
provisions allowing public utilities to provide telecommunications services
directly) and may impose additional regulatory costs (for example, provisions
requiring contributions to universal service by providers of both interstate and
intrastate telecommunications). The Company cannot predict the impact of such
legislative actions on its operations.
 
     The foregoing description of certain regulatory factors does not purport to
be a complete summary of all present and proposed legislation and regulations
pertaining to the Company's operations.
 
SEASONALITY
 
     Generally, Metrocall's operating results are not significantly affected by
seasonal factors. However, selected markets reflect slower new pager
replacements during the winter months.
 
TRADEMARKS; SERVICE MARKS
 
     "Metrocall" is a registered trademark with the U.S. Patent and Trademark
Office ("Trademark Office") and is owned by the Company. The Company markets its
paging services under the service marks "Datacall," "Metronet" and
"Metromessage." In addition, the Company owns the service marks "In Touch,"
which it has used in connection with its paging services, and "Metrotext", which
it has used in connection with its marketing of computer programs designed for
use in transmitting alphanumeric messages from personal computers to pagers.
Copyright registration has been granted to the Metrotext computer program.
During 1996, the Trademark Office granted service marks for "Metrofax" and "The
Power in Paging." The Company has applications with the Trademark Office for
service marks "One Touch," "EZ Pack Paging" and "Notesender."
 
EMPLOYEES
 
     As of December 31, 1996, the Company had 2,321 full and part-time
employees, none of whom is represented by a labor union. The Company believes
that its relationship with its employees is good.
 
                                       14
<PAGE>   16
 
ITEM 2. PROPERTIES
 
     The Company does not hold title to any real property, although the Company
and its affiliates own interests in certain properties. At December 31, 1996,
the Company leased commercial office and retail space at approximately 130
locations in approximately 32 markets used in conjunction with its paging
operations. These office leases provide for monthly payments ranging from
approximately $450 to $40,000 and expire, subject to renewal options, on various
dates through July 2010.
 
     In April 1994, Metrocall entered into a 10-year lease for additional office
space near its existing headquarters building. The lease may be renewed for two
additional five-year periods. The lease provided for initial annual rent of
approximately $450,000 or $37,500 per month, with annual escalation of 3%. In
connection with this lease, Metrocall also has an option, exercisable from
January 2, 1995 through December 31, 1997, to acquire a 51% interest in the
property for approximately $2.9 million. On January 1, 1997, the Company expand
the office space under this lease increasing total payments to approximately
$68,000 per month.
 
     The Company leases sites for its transmitters on commercial broadcast
towers, buildings and other fixed structures. During 1996, the Company leased
transmitter sites for monthly rentals ranging from approximately $100 to $6,000
that expire, subject to renewal options, on various dates through June 2012.
 
ITEM 3. LITIGATION
 
     The Company is subject to certain legal and regulatory matters in the
normal course of business. In the opinion of management, the outcome of such
assertions will not have a material adverse effect on the financial position or
the results of the operations of the Company.
 
     In April 1996, the Company entered into an agreement to purchase certain of
the assets of Source One Wireless, Inc. ("Source One") and placed $1 million
cash in escrow. On June 26, 1996, the Company advised Source One that Source One
had failed to meet certain conditions to completion of the transaction and
terminated the agreement. On September 20, 1996, Source One filed an action in
the Circuit Court of Cook County, Illinois claiming that the Company had
breached the agreement and seeking specific performance of the purchase
agreement or unspecified damages in excess of $80 million. The Company intends
to vigorously defend the claims in this action and believes it has meritorious
defenses to this action.
 
     The Company has received communications from a seller in connection with an
acquisition that occurred in 1994 asserting damages resulting from alleged
misrepresentations in connection with the acquisition. The seller, who received
shares of the Company's Common Stock as acquisition consideration, is seeking to
receive additional shares of Common Stock and participation on the Company's
board of directors, among other requests. To date, no claim has been filed;
however, if necessary, management will vigorously defend any legal actions that
might arise from such assertions.

     On February 28, 1997, the last reported sales price of the Common Stock on
The Nasdaq National Market was $5 3/4 per share. As of February 28, 1997, the
Company had approximately 299 stockholders of record.
 
     Dividend Policy.  The Company has not declared or paid any cash dividends
or distributions on its capital stock since its initial public offering of
Common Stock in 1993. The Company currently intends to retain future earnings to
finance the growth and development of its business and does not anticipate
paying any cash dividends on the Common Stock in the foreseeable future. Future
cash dividends, if any, will be determined by the Board of Directors, and will
be based upon the Company's earnings, capital requirements, financial condition
and other factors deemed relevant by the Board of Directors. In addition,
certain covenants in the Company's Credit Facility, its Indenture and the terms
of the Series A Convertible Preferred Stock restrict or prohibit the payment of
cash dividends on the Company's Common Stock.
 
   
     Unregistered Securities.  On November 15, 1996, the Company issued 159,600
shares of Series A Convertible Preferred Stock ("Series A Preferred Stock") and
159,600 warrants representing the right to purchase an aggregate of 2.915
million shares of Metrocall Common Stock ("Warrants"). The aggregate purchase
price for the Series A Preferred Stock and the Warrants was $39.9 million. The
purchasers of these securities were John Hancock Mutual Life Insurance Company,
SunAmerica, Inc. and UBS Capital, LLC. Because the securities were sold to
qualified institutional buyers in a transaction not involving a public offering,
the sale was exempt from registration pursuant to Section 4(2) of the Securities
Act of 1933, as amended (the "Securities Act").
    
 
   
     The Series A Preferred Stock has a stated vale of $250 per share, and
carries a 14% dividend (subject to increase upon the occurrence of certain
events) payable in cash or additional shares of Series A Preferred Stock at the
election of the Company, a liquidation preference and redemption value of $250
per share, certain redemption rights and the right to elect directors of
Metrocall. In addition, beginning November 15, 2001, holders of Series A
Preferred Stock have the right to convert their Series A Preferred Stock
(including shares issued as dividends) into shares of Metrocall Common Stock
based upon the market price of Metrocall Common Stock at the time of conversion.
Series A Preferred Stock may, at the option of holders, be converted sooner upon
certain change of control events of Metrocall, as defined in the Certificate of
Designation for the Series A Preferred Stock.
    
 
   
     Each Warrant represents to right of the holder to purchase 18,266 shares of
Metrocall Common Stock, or an aggregate of 2.915 million shares. The exercise
price per share is $7.40. The Warrants contain certain provisions for adjustment
in the exercise price in the event Metrocall sells common stock or rights to
purchase common stock in private transactions for less than 125% of the then
current market price and other customary anti-dilution provisions. The Warrants
expire November 15, 2001. The Company has registered under the Securities Act
the resale of shares that may be obtained upon exercise of the Warrants.

          NOTES TO SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA
 
(1) 1994 and 1996 include the results of operations of acquired companies from
    their respective acquisition dates (see Note 3 to consolidated financial
    statements).
 
(2) Includes the impact of one-time, non-recurring charges for the forgiveness
    of certain stockholder notes receivable of approximately $4.8 million in
    1993, and for severance and other compensation costs incurred as part of a
    management reorganization charge of approximately $2.0 million in 1995.
 
   
(3) In 1993, 1994 and 1995 the Company refinanced balances outstanding under its
    then existing credit facilities. As a result of this refinancing the Company
    recorded extraordinary items of $439,000, $1.3 million and $2.7 million,
    respectively, representing charges to expense unamortized deferred financing
    costs and other costs, net of any income tax benefits, related to those
    credit facilities. In 1996, the Company recorded an extraordinary item for
    costs of approximately $3.7 million paid to purchase the A+ Network 11 7/8%
    senior subordinated notes outstanding. Additionally, the Company incurred
    breakage fees of approximately $1.7 million associated with the termination
    of two interest rate swap agreements in 1995. Costs associated with this
    termination have been included in interest and other (expense) income in the
    1995 statement of operations.
    
 
(4) EBITDA (earnings before interest, taxes, depreciation and amortization, and
    certain one-time charges), while not a measure under generally accepted
    accounting principles ("GAAP"), is a standard measure of financial
    performance in the paging industry; EBITDA should not be considered in
    isolation or as an alternative to net income (loss), income (loss) from
    operations, cash flows from operating activities, or any other measure of
    performance under GAAP. EBITDA is, however, an approximation of the primary
    financial measure by which the Company's covenants are calculated under the
    Indenture and its credit facility. See "Management's Discussion and Analysis
    of Financial Condition and Results of Operations -- Liquidity and Capital
    Resources" for discussion of significant capital requirements and
    commitments. EBITDA excludes non-recurring charges for the forgiveness of
    certain stockholder notes receivable of approximately $4.8 million in 1993,
    and approximately $2.0 million incurred as part of a management
    reorganization charge in 1995.
 
(5) EBITDA margin is calculated by dividing (a) EBITDA by (b) the sum of (total
    revenues less the net book value of products sold).
 
(6) ARPU (average monthly paging revenue per unit) is calculated by dividing (a)
    service, rent and maintenance revenues for the period by (b) the average
    number of units in service for the period. ARPU calculation excludes
    revenues derived from non-paging services such as telemessaging, long
    distance and cellular telephone.
 
(7) Average monthly operating expense per unit is calculated by dividing (a)
    total recurring operating expenses before depreciation and amortization for
    the period by (b) the average number of units in service for the period. For
    this calculation, operating expenses exclude non-recurring charges for the
    forgiveness of certain stockholder notes receivable of approximately $4.8
    million in 1993, and approximately $2.0 million incurred as a part of a
    management reorganization charge in 1995.

OVERVIEW
 
     Metrocall is the fifth largest paging company in the United States, based
on 2,142,351 pagers in service as of December 31, 1996. From December 31, 1993
to December 31, 1996, the Company has increased its base of pagers in service
from less than 250,000 to more than 2.1 million. This growth has been
accomplished through a combination of internal growth and a program of mergers
and acquisitions. In July, August, and November 1996, Metrocall completed the
Parkway Paging, Satellite Paging, Message Network and A+ Network acquisitions,
respectively. As a result of these acquisitions, Metrocall added approximately
900,000 subscribers to its base of pagers in service. In addition to the
acquisitions, the Company grew its subscriber base by approximately 32% through
internal growth. During 1995, the Company's total pagers in service grew
approximately 25%, exclusively through internal growth. In August and November
1994, Metrocall completed the FirstPAGE acquisition and the MetroPaging
acquisition, respectively. As a result of these acquisitions, Metrocall added
approximately 420,000 subscribers to its base of pagers in service, more than
doubling its total pagers in service during 1994 alone. The consolidated
statements of operations for the years ended December 31, 1994 and 1996 includes
the results of operations for acquired companies from their respective
acquisition dates only. The definitions below relate to management's discussion
of the Company's results of operations that follows.
 
     - Service, rent and maintenance revenues: include primarily monthly,
       quarterly, semi-annually and annually billed recurring revenue, not
       generally dependent on usage, charged to subscribers for paging and
       related services such as voice mail and pager repair and replacement.
       Service, rent and maintenance revenues also include revenues derived from
       telemessaging, cellular and long distance services.
 
     - Net revenues: include service, rent and maintenance revenues and sales of
       customer owned and maintained ("COAM") pagers less net book value of
       pagers sold.
 
     - Service, rent and maintenance expenses: include costs related to the
       management, operation and maintenance of the Company's network systems
       and customer support centers.
 
     - Selling and marketing expenses: include salaries, commissions and
       administrative costs for the Company's sales force and related marketing
       and advertising expenses.
 
     - General and administrative expenses: include executive management,
       accounting, office telephone, rents and maintenance, information services
       and employee benefits.
 
                                       20

     The Company derives the majority of its revenues from fixed periodic
(usually monthly) fees, generally not dependent on usage, charged to subscribers
for paging services. While a subscriber continues to use the Company's service,
operating results benefit from this recurring revenue stream with minimal
requirements for incremental selling expenses or other fixed costs. The
Company's total revenues have grown from $37.7 million for the year ended
December 31, 1993 to approximately $150.0 million for the year ended December
31, 1996.
 
   
     In recent years, paging, including paging related services, has been one of
the fastest growing, most cost competitive forms of wireless communications.
Industry experts estimate that total pagers in service will increase to more
than 75 million by the end of the century from approximately 43 million in 1996.
In order to capitalize on this anticipated growth, the Company has expanded its
channels of distribution to include Company-owned and operated retail stores,
strategic partnerships and alliances, franchises and internet sales, among
others; with each focusing on the sale rather than lease of pagers. While there
has been an increase in the percentage of pagers sold through indirect, as
opposed to direct, channels, the Company does not believe this change will have
a material effect on its results of operations or liquidity. The Company's
average monthly service, rent and maintenance revenue per unit ("ARPU") for
paging services for the years ended December 31, 1995 and 1996 was $9.15 and
$8.01, respectively. This decline in ARPU is largely a function of the changing
mix of distribution channels through internal growth and acquisitions and an
overall average ARPU decline of approximately 6.6%. In order to increase
penetration and maximize utilization of its network, the Company emphasizes a
number of distribution channels characterized by lower ARPU, with
correspondingly lower costs. For example, the Company's strategic partners and
third-party resellers do not lease pagers from the Company and generally
purchase services in large quantities at discounted prices. This lower revenue
base is, however, offset by lower sales and administrative costs for their
subscribers. The Company has reduced capital expenditure requirements for these
new customers, as they do not need to make investments in paging equipment for
these subscribers. More customers are purchasing pagers either directly from the
Company or through Company owned retail stores, third-party retail outlets and
the Company's strategic partners. While the Company does not earn lease revenues
from these sold units, the overall capital expenditure requirement is reduced or
eliminated. Enhanced services have partially offset declines in ARPU. The
Company has been successful in marketing enhanced services such as nationwide
paging service and voice mail, to its subscriber base, as well as branded
customer service and billing services for the Company's strategic partners and
franchisees. Such services carry a low incremental cost to the Company. The
Company is attempting to offset declines in ARPU through the expansion of its
distribution channels, continued marketing of enhanced services and expansion
into support functions, including billing and customer service.
    
 
     The Company's growth and expansion into new markets, whether internal or
through acquisitions, require significant capital investment for the
installation of paging equipment and technical infrastructure. Additionally, the
Company incurred significant expenditures throughout the first three quarters of
1996 while it completed the expansion and buildout of its nationwide network.
The Metrocall Nationwide Network serves the top 100 Standard Metropolitan
Statistical Areas. The Company also purchases pagers for that portion of its
subscriber base that leases equipment from the Company.
 
     The Company's focus is now on integrating its 1996 acquisitions and
increasing the utilization of its networks constructed during 1996. As a result
of the completion of the Company's nationwide network and an emphasis on
distribution channels through which pagers are sold rather than leased, capital
expenditures are expected to be reduced in 1997. The combination of growing
revenues and EBITDA along with reduced levels of capital expenditures should
result in improving leverage ratios and access to capital in future periods.
While the Company has no current outstanding commitments, other than the
agreement to acquire the assets of Page America, the Company will continue to
evaluate strategic acquisition targets in the future. Potential future
acquisitions would be evaluated on significant strategic opportunities such as
geographic coverage and regulatory licenses and other factors including overall
valuation, consideration and availability of financing.
 
   
     The Company's long-term strategy is to continue to expand its business by
providing paging and other wireless communication services to an increasingly
broad base of subscribers throughout the United States, while increasing total
revenues and EBITDA and de-emphasizing that portion of the business which has
historically leased pagers. The Company believes that increases in revenues from
the sale of pagers and service
    
 
                                       21
<PAGE>   23
 
   
revenue from providing paging service to such pagers will more than make up for
losses of rental revenues derived from leasing pagers, which has increasingly
involved high volume, lower margin transactions. The Company is seeking to
increase its base of subscribers by expanding its operations in existing,
contiguous and other markets, through start-up operations and internal growth.
As discussed above, the Company significantly expanded its geographic coverage
and subscriber base through four acquisitions in 1996. Furthermore, the Company
has signed a definitive acquisition agreement to acquire the assets of Page
America, as discussed below.

---------------
(1) EBITDA (earnings before interest, taxes, depreciation and amortization and
    certain one-time charges), while not a measure under GAAP, is a standard
    measure of financial performance in the paging industry; EBITDA should not
    be considered in isolation or as an alternative to net income (loss), income
    (loss) from operations, cash flows from operating activities or any other
    measure of performance under GAAP. EBITDA is, however, an approximation of
    the primary financial measure by which the Company's covenants are
    calculated under the Indenture and its credit facility. See "-- Liquidity
    and Capital Resources" for discussion of significant capital requirements
    and commitments. EBITDA excludes one-time, non-recurring charges for
    severance and other compensation costs of approximately $2.0 million
    incurred as a part of a management reorganization charge in 1995.
 
(2) ARPU (average monthly paging revenue per unit) is calculated by dividing (a)
    service, rent and maintenance revenues for the period by (b) the average
    number of units in service for the period. ARPU calculation excludes
    revenues derived from non-paging services such as telemessaging, long
    distance and cellular telephone.
 
(3) Average monthly operating expense per unit is calculated by dividing (a)
    total recurring operating expenses before depreciation and amortization for
    the period by (b) the average number of units in service for the period. For
    this calculation, operating expenses exclude a non-recurring charge of
    approximately $2.0 million incurred as a part of a management reorganization
    in 1995.

YEAR ENDED DECEMBER 31, 1996 COMPARED WITH DECEMBER 31, 1995
 
     Total revenues increased approximately $39.1 million from $110.9 million in
the year ended December 31, 1995 ("1995") to approximately $150.0 million for
the year ended December 31, 1996 ("1996"). Net revenues increased approximately
$33.0 million, or 34.6% from $95.3 million in 1995 to $128.3 million in 1996.
The increase is attributable to greater service revenues due to the growth of
pagers in service from 944,013 at December 31, 1995 to 2,142,351 at December 31,
1996. The Parkway, Satellite Paging, Message Network and A+ Network
acquisitions, completed in July, August and November 1996, respectively, added
approximately 900,000 pagers to the Company's subscriber base. Operations of the
acquired companies are included in the results of operations from their
respective acquisition dates. ARPU for paging services has declined from $9.15
in 1995 to $8.01 in 1996 due primarily to the increase in the base of customers
serviced through indirect channels (which generally have lower ARPU due to
volume discounts) and an overall decline in monthly rates of approximately 6.6%
during 1996. On a pro forma basis, assuming each of the acquisitions occurred on
January 1, 1996, the ARPU for paging services (excluding long distance,
telemessaging and cellular services) is estimated to have been $8.52 and $8.21
per month for the year and quarter ended December 31, 1996. Factors affecting
ARPU in future periods include distribution mix of new subscribers, competition
and new technologies, among others. There can be no assurance that ARPU will not
decline in future periods.
 
     Net book value of products sold increased approximately $6.1 million from
$15.5 million in 1995 to $21.6 million in 1996. The gross margin on products
sold decreased from 17.0% in 1995 to 16.6% in 1996. Net book value of products
sold increased principally due to the increase in product sales, partially
offset by increased depreciation expense.
 
     Overall, the Company has experienced a decrease in total average operating
expenses per unit in service (operating expenses per unit before depreciation
and amortization) from 1995 to 1996. Average monthly operating expenses per unit
decreased from $6.71 for 1995 to $6.28 for 1996. Each component of operating
expenses is discussed separately below. Acquisitions require integration of each
company's administrative, finance, sales and marketing organizations, as well as
the integration of each company's technical network operations. Until the
operations of A+ Network are fully integrated, the Company expects average
operating expenses per unit to increase in 1997 from historical 1996 amounts. On
a pro forma basis, assuming that all acquisitions were completed as of January
1, 1996, the Company's average monthly total operating expense per unit in
service is estimated to have been approximately $7.05 for 1996 and $6.63 for the
quarter ended December 31, 1996. The increase in average monthly total operating
expense per unit is primarily due to higher overall per unit operating costs and
a lower number of subscribers per employee in the A+ Network operations.
 
     Service, rent and maintenance expenses increased approximately $11.0
million from $27.3 million in 1995 to $38.3 million in 1996 and increased as a
percentage of net revenues from 28.6% in 1995 to 29.9% in 1996. The Company
estimates that this overall increase in service, rent and maintenance expenses
is primarily attributable to the acquisitions of Parkway Paging ($1.1 million),
Satellite Paging and Message Network ($1.2 million), and A+ Network ($2.4
million) and increased carrier line costs paid to third party service providers
($2.8 million), increased transmitter site rental costs associated with expanded
system coverage ($1.7 million) and increased personnel costs ($1.7 million). On
a per unit basis, monthly service, rent and maintenance expenses decreased from
$2.71 in 1995 to $2.52 in 1996 as a result of combining operations for greater
efficiencies. On a pro forma basis, assuming that all acquisitions were
completed as of January 1, 1996, the Company's average monthly service, rent and
maintenance expense per unit in service is estimated to have been approximately
$2.55 for 1996 and $2.33 for the quarter ended December 31, 1996.
 
     Selling and marketing expenses increased approximately $8.5 million from
$15.7 million in 1995 to $24.2 million in 1996 and increased as a percentage of
net revenues from 16.4% in 1995 to 18.9% in 1996. The Company estimates this
increase in selling and marketing expenses is primarily associated with the
acquisitions of Parkway Paging ($0.7 million), Satellite Paging and Message
Network ($0.5 million), and A+ Network ($2.6 million) and in part due to
increased personnel costs, including salaries and commissions, ($3.6 million),
advertising and promotion ($0.7 million), rents ($0.2 million) and travel
expenses ($0.2
 
                                       24
<PAGE>   26
 
million). Monthly selling and marketing expenses per unit have increased
slightly from $1.55 in 1995 to $1.59 in 1996, due primarily to increasing the
Company's sales force as a result of acquisitions in new geographic areas for
the Company. Selling and marketing expenses may increase as a percentage of
revenue as the Company continues to increase markets and expand geographic
coverage. On a pro forma basis, assuming that all acquisitions were completed as
of January 1, 1996, the Company's average monthly selling and marketing expense
per unit in service for the year and quarter ended December 31, 1996 is
estimated to have been approximately $1.77 and $1.68, respectively.
 
     General and administrative expenses increased approximately $8.4 million
from $24.6 million in 1995 to $33.0 million in 1996 and decreased as a
percentage of net revenues from 25.9% in 1995 to 25.7% in 1996. The Company
estimates that this increase in general and administrative expenses is primarily
attributable to the acquisitions of Parkway Paging ($0.3 million), Satellite
Paging and Message Network ($0.5 million) and A+ Network ($3.7 million) from
their respective acquisition dates, offset by synergies resulting from the
reduction of duplicative functions, and in part due to increased expenses for
collection activities ($0.6 million), professional services, including legal and
accounting fees, ($1.2 million) and general corporate expenses ($2.1 million),
including personnel, taxes and maintenance. Monthly general and administrative
expenses per unit have decreased from $2.45 in 1995 to $2.17 in 1996. On a pro
forma basis, assuming that all acquisitions were completed as of January 1,
1996, the Company's average monthly general and administrative expense per unit
in service for the year and quarter ended December 31, 1996 is estimated to have
been approximately $2.73 and $2.62, respectively.
 
     EBITDA increased approximately $5.0 million from $27.8 million in 1995 to
$32.8 million in 1996. As a percentage of net revenues, EBITDA decreased from
29.1% in 1995 to 25.5% in 1996.
 
     Depreciation and amortization increased approximately $26.7 million from
$31.5 million in 1995 to $58.2 million in 1996 and increased as a percentage of
net revenues from 33.0% to 45.4% for 1995 and 1996, respectively. The Company
estimates that the increase in total depreciation expense resulted from
depreciation on additional pagers in service ($12.2 million) and paging
equipment ($2.7 million), other operating equipment ($3.4 million) and
depreciation of assets acquired in the acquisitions of Parkway, Satellite Paging
and Message Network and A+ Network ($2.0 million). Amortization increased
substantially during 1996 due to the amortization of goodwill and other
intangibles recorded in the acquisitions completed in 1996. Effective July 1,
1996, the Company changed the estimated useful lives of certain intangibles
acquired in 1994, including goodwill and regulatory licenses issued by the FCC
from 40 years to 15 years for goodwill and from 40 years to 25 years for FCC
licenses. The impact of these changes was to increase amortization expense for
1996 by approximately $1.3 million.
 
   
     Interest and other income (expense) decreased approximately $0.9 million
from $0.3 million in 1995 to a loss of $0.6 million in 1996. The decrease is the
result of the recognition of the Company's share of losses of A+ Network (from
June 1996 through November 15, 1996, during which time the Company's investment
was being accounted for under the equity method) of $4.1 million, and the
Company's equity in the Solo America loss ($0.2 million). These losses were
partially offset by a gain recognized on the sale of equipment ($1.2 million)
and increased interest income reflecting higher cash balances in the first half
of 1996.
    
 
     Interest expense increased approximately $7.9 million from $12.5 million in
1995 to $20.4 million in 1996 primarily due to the Company's 10 3/8% senior
subordinated notes being outstanding all of 1996. Since net proceeds from the
subordinated notes offering were used partially to refinance existing debt, the
impact is to increase interest expense by the marginal increase in the interest
rate of the debt.
 
     During the fourth quarter of 1996, the Company recognized an extraordinary
charge of approximately $3.7 million to expense fees and cash payments incurred
in the tender and consent solicitation for the A+ Network 11 7/8% senior
subordinated notes (the "A+ Notes") outstanding.
 
   
     The Company's loss attributable to common stockholders increased
approximately $29.8 million from $20.1 million in 1995 to $49.9 million in 1996.
The increase in the loss attributable to common stockholders is primarily
attributable to increased depreciation and amortization expense and increased
interest costs in 1996. The Company's net losses are expected to continue for
additional periods in the future. In addition, the Page
    
 
                                       25
<PAGE>   27
 
   
America acquisition may result in increased net losses as a result of additional
depreciation and amortization and interest expense attributable to the Page
America transaction and borrowings to pay the cash portion of the purchase
price. In November 1996, the Company issued $39.9 million of Series A
Convertible Preferred Stock ("Series A Preferred") together with warrants to
acquire approximately 2.9 million shares of the Company's Common Stock with an
exercise price of $7.40 per share. The Series A Preferred bears dividends at 14%
of the stated value per year. Total dividends accrued but unpaid at December 31,
1996 were approximately $698,000. The total value allocated to the warrants,
$7.9 million or $2.70 per share, will be accreted over the term of the Series A
Preferred as preferred dividends. Since the issuance of the Series A Preferred,
accretion of the allocated value of the warrants was approximately $82,000.
    
 
YEAR ENDED DECEMBER 31, 1995 COMPARED WITH DECEMBER 31, 1994
 
     Net revenues increased approximately $44.4 million, or 87.2%, from $50.9
million in the year ended December 31, 1994 ("1994"), to $95.3 million for the
year ended December 31, 1995 ("1995"). The increase is attributable to greater
service revenues due to the growth of pagers in service from 755,547 at December
31, 1994 to 944,013 at December 31, 1995. The FirstPAGE and MetroPaging
acquisitions, completed on August 31, 1994 and November 29, 1994, respectively,
added approximately 420,000 pagers in service. Operations of FirstPAGE and
MetroPaging are included in the results of operations from their respective
acquisition dates. ARPU has declined from $10.53 in 1994 to $9.15 in 1995 due
primarily to the increase in the base of customers serviced through indirect
channels and, to a lesser extent, the inclusion of the operations of FirstPAGE
and MetroPaging. Declining ARPU during 1995 is generally offset by increased
sales of enhanced services including the Nationwide Network services. Product
sales increased $10.6 million from $8.1 million in 1994 to $18.7 million in 1995
largely due to the FirstPAGE and MetroPaging acquisitions, and increased as a
percentage of net revenues from 16.0% in 1994 to 19.6% in 1995 due to increased
sales to resellers and other indirect sales channels.
 
     Net book value of products sold increased approximately $8.5 million from
$7.0 million in 1994 to $15.5 million in 1995. The gross margin on products sold
increased from 14.5% in 1994 to 17.0% in 1995. Net book value of products sold
increased principally due to the increase in product sales, partially offset by
increased depreciation expense.
 
     Overall, the Company has experienced a decline in total average operating
expenses per unit in service (operating expenses per unit before depreciation
and amortization) from 1994 to 1995. Average monthly operating expenses per unit
decreased from $7.36 for 1994 to $6.71 for 1995. Each operating expense is
discussed separately below.
 
     Service, rent and maintenance expenses increased approximately $13.3
million from $14.0 million in 1994 to $27.3 million in 1995 and increased as a
percentage of net revenues from 27.5% in 1994 to 28.6% in 1995. The Company
estimates that this overall increase in service, rent and maintenance expenses
is primarily attributable to the acquisitions of FirstPAGE ($6.5 million) and
MetroPaging ($5.3 million) and, to a lesser extent, increased carrier line costs
paid to third party service providers ($0.8 million), increased transmitter site
rental costs associated with expanded system coverage ($0.4 million) and
increased personnel costs ($0.3 million). On a per-unit basis, monthly service,
rent and maintenance expenses declined from $2.97 in 1994 to $2.71 in 1995 as a
result of increased efficiencies due largely to the integration of the FirstPAGE
and MetroPaging operations.
 
     Selling and marketing expenses increased approximately $8.2 million from
$7.4 million in 1994 to $15.6 million in 1995 and increased as a percentage of
net revenues from 14.6% in 1994 to 16.4% in 1995. The Company estimates this
increase in selling and marketing expenses is primarily associated with the
acquisitions of FirstPAGE ($2.5 million) and MetroPaging ($4.2 million), and in
part due to increased personnel costs ($1.2 million) and travel expenses ($0.3
million). Additionally, the Company commenced operations in six new markets
during 1995 including Boston, Pittsburgh, Miami, San Diego, Phoenix and Las
Vegas. Monthly selling and marketing expenses per unit have declined from $1.57
in 1994 to $1.55 in 1995, due primarily to efficiencies gained by consolidating
the Company's sales force with those of FirstPAGE and
 
                                       26
<PAGE>   28
 
MetroPaging. Selling and marketing expenses may increase as a percentage of
revenue as the Company continues to increase markets and expand geographic
coverage.
 
     General and administrative expenses increased approximately $11.3 million
from $13.3 million in 1994 to $24.6 million in 1995 and decreased as a
percentage of net revenues from 26.2% in 1994 to 25.9% in 1995. The Company
estimates that this increase in general and administrative expenses is primarily
attributable to the acquisitions of FirstPAGE ($7.2 million) and MetroPaging
($4.9 million) from their respective acquisition dates, offset by synergies
resulting from the reduction of duplicative functions and lower personnel costs
($0.8 million). Monthly general and administrative expenses per unit have
declined from $2.82 in 1994 to $2.45 in 1995. General and administrative
expenses per unit should continue to decline as the Company realizes continued
benefits from the integration of its back-office operations and economies of
scale.
 
     In 1995, the Company recognized a charge for $2.0 million as a management
reorganization charge to accrue for severance and other compensation costs
associated with the replacement of the Company's Chairman of the Board and
resignation of its Chief Executive Officer. In addition, the Company instituted
a reduction-in-force whereby certain non-sales positions were eliminated.
Management estimates the reorganization and reduction-in-force will result in
approximately $1.0 million of savings in 1996.
 
     EBITDA increased approximately $11.6 million from $16.2 million in 1994 to
$27.8 million in 1995. As a percentage of net revenues, EBITDA decreased from
31.7% in 1994 to 29.1% in 1995.
 
     Depreciation and amortization increased approximately $17.7 million from
$13.8 million in 1994 to $31.5 million in 1995 and increased as a percentage of
net revenues from 27.2% to 33.1% for 1994 and 1995, respectively. The Company
estimates that the increase in total depreciation expense resulted from
depreciation on additional pagers in service ($5.8 million) and paging equipment
($2.1 million), other operating equipment ($1.2 million) and depreciation of
assets acquired in the FirstPAGE acquisition ($2.6 million) and MetroPaging
acquisition ($1.1 million). Amortization increased substantially during 1995 due
to the amortization of goodwill and other intangibles recorded in the
acquisitions of FirstPAGE ($3.2 million) and MetroPaging ($1.7 million).
Beginning in the quarter ended September 30, 1995, the Company began recording
all purchases of new pagers as a component of subscriber paging equipment.
Amounts previously classified as inventories in the prior year financial
statements have been reclassified to conform to the current period's
presentation. This resulted in an increase to depreciation expense of
approximately $2.7 million.
 
   
     Interest and other income increased approximately $0.1 million from $0.2
million in 1994 to $0.3 million in 1995. The increase is the result of interest
earned on cash balances, resulting from the completion of public offerings of
4.0 million shares of the Company's common stock and $150.0 million Senior
Subordinated Notes, net of amounts used to repay existing debt and other costs
largely offset by breakage fees of $1.7 million associated with the termination
of two interest rate swap agreements.
    
 
     Interest expense increased approximately $8.8 million from $3.7 million in
1994 to $12.5 million in 1995. Interest expense increased due to the completion
in October 1995 of the Company's public offering of senior subordinated notes
bearing interest at 10 3/8%, payable semiannually on April 1 and October 1, due
2007. This raised the Company's average level of debt outstanding and increased
the average interest rate in effect in 1995.
 
   
     During the fourth quarter of 1995, the Company recognized an extraordinary
charge of $2.7 million to expense unamortized debt financing costs and other
costs associated with the repayment of balances outstanding on its credit
agreement in October 1995.
    
 
     The Company's net loss increased approximately $17.7 million from $2.4
million in 1994 to $20.1 million in 1995.
 
INFLATION
 
     Inflation is not a material factor affecting the Company's business. Paging
system equipment and operating costs have not increased while pager costs have
declined significantly in recent years. This reduction
 
                                       27
<PAGE>   29
 
in costs has been reflected in lower prices charged to the Company's
subscribers. General operating expenses such as salaries, employee benefits and
occupancy costs are, however, subject to inflationary pressures.
 
NEW ACCOUNTING PRONOUNCEMENT
 
     On March 3, 1997, the Financial Accounting Standards Board released
Statement No. 128, "Earnings Per Share." Statement 128 requires dual
presentation of basic and diluted earnings per share on the face of the income
statement for all periods presented. Basic earnings per share excludes dilution
and is computed by dividing income available to common stockholders by the
weighted-average number of common shares outstanding for the period. Diluted
earnings per share reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity. Diluted earnings per share is computed similarly
to fully diluted earnings per share pursuant to Accounting Principles Bulletin
No. 15. Statement 128 is effective for fiscal years ending after December 15,
1997, and when adopted, it will require restatement of prior years' earnings per
share.
 
     Since the effect of outstanding options is antidilutive, they have been
excluded from the Company's computation of net loss per share. Accordingly,
management does not believe that Statement 128 will have an impact upon
historical net loss per share as reported.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's operations require the availability of substantial funds to
finance the growth of its existing paging operations and customer base,
development and construction of future wireless communications networks,
expansion into new markets and the acquisition of other wireless communications
companies. Further cash requirements also include debt service, working capital
and general corporate requirements.
 
   
     The Company has financed its internal growth in 1996 through its operating
cash flow, the use of available cash and, to a limited extent, borrowings under
the Company's credit facility. Net cash provided by operating activities
increased from $14.0 million for the year ended December 31, 1995 to $15.6
million for the year ended December 31, 1996. Of the $125.0 million of A+ Notes
outstanding, the Company refinanced approximately $122.5 million under its
credit facility. Through the refinancing of the A+ Notes, the Company expects to
lower its overall interest costs in future periods. See Note 7 to the Company's
consolidated financial statements for a discussion of the Company's credit
facility and other indebtedness.
    
 
   
     At December 31, 1996, the Company had a deficit in working capital of
approximately $7.3 million. The Company has experienced such deficits in prior
years and such deficits are likely to continue. Pursuant to the Page America
acquisition, the Company will assume current liabilities of Page America. This
may result in a significant increase in the Company's working capital deficit.
The Company attempts, when possible, to finance its growth through operating
cash flow and available cash balances rather than incurring additional
indebtedness. As a result, purchases of noncurrent assets, including pagers and
other network and transmission equipment, may be financed with current
liabilities (e.g., accounts payable), causing a deficit in working capital. The
Company currently has sufficient borrowing capacity available under its credit
facility, discussed below, to fund the working capital deficit at December 31,
1996.
    
 
     Cash flows used in investing activities were primarily to fund purchases of
property and equipment and complete the acquisitions of Parkway, Satellite
Paging, Message Network and A+ Network. Capital expenditures were approximately
$62.1 million and $44.1 million for the years ended December 31, 1996 and 1995,
respectively. The Company experienced much greater capital expenditure
requirements in 1996 due to the completion of the Company's Nationwide Network,
the expansion and upgrading of the Company's management information, database
and customer service systems and increased pager placements. In June 1996, the
Company completed a cash offer for approximately 4.4 million shares of the
outstanding common stock of A+ Network for $91.8 million. In July and August
1996, the Company acquired Parkway and Satellite Paging and Message Network,
respectively. The acquisitions of Parkway and Satellite were financed primarily
with cash payments totaling approximately $45 million and the issuance of shares
of the Company's Common Stock.
 
                                       28
<PAGE>   30
 
   
     Cash flows provided by financing activities for the year ended December 31,
1996, included payments on long-term debt approximately $25.5 million.
Borrowings under the Company's credit facility increased by approximately $194.9
million primarily for the acquisitions of Parkway ($28 million), Satellite and
Message Network ($17 million) and the purchase of the A+ Notes ($122.5 million)
and other working capital requirements. Borrowings under the Company's credit
facility are expected to further increase to finance the cash portion of the
Page America acquisition ($25 million plus, at the Company's option, additional
cash in substitution for all or a portion of the consideration payable in
securities of the Company). In November 1996, the Company sold Series A
Preferred, bearing dividends at 14% of the stated value per year, to a group of
investors. Net proceeds were approximately $38.3 million. Dividends on the
Series A Preferred may be paid in either cash or additional shares of Series A
Preferred, at the Company's option. However, under certain circumstances, as
defined in the certificate of designation, the dividend rate may increase to 16%
and dividends must be paid in cash to the extent permitted by the terms of the
Company's debt agreements. Further, Metrocall is required to redeem all
outstanding shares of Series A Preferred (including dividend shares) in November
2008 unless the holders have previously converted such shares to Common Stock.
From the net proceeds of the Series A Preferred, the Company repaid $25 million
outstanding under the credit facility.
    
 
   
     Total capital expenditures during 1997 are estimated to be approximately
$60 million primarily for the acquisition of pagers, paging and transmission
equipment and information system enhancement. This estimate does not include the
cash consideration to be paid in the Page America acquisition, or the related
transaction costs, but does include estimated capital expenditures related to
the Page America assets after the acquisition. The Company expects that its
capital expenditures in 1997 will be financed through a combination of operating
cash flow and borrowings. Projected capital expenditures are subject to change
based on the Company's internal growth, general business and economic conditions
and competitive pressures. The Company has aggregate rental commitments under
operating leases of approximately $11.9 million, $9.5 million and $6.4 million
for the years ending December 31, 1997, 1998 and 1999, respectively. Future cash
requirements include debt service costs, primarily interest. Based on existing
debt at December 31, 1996, estimated interest payments, including fees, in 1997
are approximately $31.3 million. Principal payments due in 1997 are
approximately $0.7 million. The Company will complete the acquisition of Page
America Group, Inc. during 1997 which is discussed further below.
    
 
     In January 1996, the Company completed a management reorganization. Under
the reorganization, the Company's Chairman of the Board was replaced and the
Company's Chief Executive Officer resigned. Severance and other separation costs
for the former Chairman and former Chief Executive Officer were accrued and
recorded as a management reorganization charge in the accompanying consolidated
financial statements as of and for the year ended December 31, 1995.
Additionally, certain nonsales employees were terminated and related severance
costs were included in the management reorganization charge. Severance costs
included approximately $285,000 of compensation expense recognized upon amending
option agreements with certain former employees and the Company's former Chief
Executive Officer to increase vesting and exercise periods. As of December 31,
1996, the balance of accrued but unpaid severance costs included in the
accompanying balance sheet was approximately $544,000.
 
     In connection with the acquisition of A+ Network, stockholders of A+
Network received approximately 8.1 million indexed Variable Common Rights
("VCRs"). Each VCR entitles the holder to receive a payment of up to $5.00 in
either the Company's Common Stock or cash, at the Company's option, if the
market value, as defined, of the Company's Common Stock at November 15, 1997, is
less than a specified target price. The target price will be adjusted downward,
but not upward, based on changes in an index composed of the average closing bid
prices of three other companies in the paging industry since the announcement of
the merger. If changes in the index cause the target price to be lower than a
floor price of $16.10 (which is not indexed and therefore not adjusted
downward), the VCR payment will be zero without regard to the trading value of
the Company's Common Stock. At November 15, 1996, the date the merger was
completed, and December 31, 1996, the target price was below the fixed floor
price of $16.10 per share resulting in no current obligation under the VCRs.
While the Company currently expects to incur no future obligations related to
the VCRs, there can be no assurance that future changes in the Company's stock
price or in the industry index, as defined in the merger agreement, will not
create an obligation for the Company in the future.

SENIOR SECURED CREDIT FACILITY
 
     On September 20, 1996, the Company amended and restated the loan agreement
governing the Company's existing credit facility. Subject to certain conditions
set forth in the new agreement, the Company may borrow up to $350 million under
two loan facilities. The first facility ("Facility A") is a $225 million
reducing revolving credit facility and the second ("Facility B") is a $125
million reducing credit facility (together Facility A and Facility B are
referred to as the "New Credit Facility"). The New Credit Facility has a term of
eight years and is secured by substantially all the assets of the Company.
Required quarterly principal repayments begin on March 31, 2000 and continue
through December 31, 2004. At December 31, 1996, a total of $169.9 million was
outstanding under the New Credit Facility. At January 1, 1997, total additional
borrowings available to the Company under the credit facility were approximately
$46.5 million. On January 14, 1997, the Company increased its borrowings under
the credit facility by $10 million primarily to fund working capital
requirements.
 
     The New Credit Facility contains various covenants that, among other
restrictions, require the Company to maintain certain financial ratios,
including total debt to annualized operating cash flow (not to exceed 6.0 to 1.0
from January 1, 1997 to December 31, 1997, and declining thereafter), senior
debt to annualized operating cash flow, annualized operating cash flow to pro
forma debt service, total sources of cash to total uses of cash, and operating
cash flow to interest expense (in each case, as such terms are defined in the
agreement relating to the New Credit Facility). The covenants also limit
additional indebtedness and future mergers and acquisitions (other than the
pending transaction with Page America discussed below) without the approval of
the lenders, and restrict the payment of cash dividends and other stockholders
distributions by Metrocall during the term of the New Credit Facility. The New
Credit Facility also prohibits certain changes in ownership control of
Metrocall, as defined, during the term of the New Credit Facility.
 
   
PENDING ACQUISITION
    
 
   
     On April 22, 1996, the Company signed a definitive acquisition agreement
(the "Page America Agreement") with Page America Group, Inc. of Hackensack, New
Jersey ("Page America"). The Page America Agreement was subsequently amended on
January 30, 1997, (the "Amended Page America Agreement"). Pursuant to the
Amended Page America Agreement, (i) Metrocall will acquire substantially all of
the assets and assume substantially all of Page America's accounts payable and
certain obligations under various office and equipment leases and (ii) Page
America will receive (a) $25 million in cash, (b) 1,500 shares of Series B
Preferred Stock having a stated value of $15 million, (c) 762,960 shares of the
Company's Common Stock and (d) additional shares of the Company's Common Stock
or other equity securities (CSE Preferred Stock, see Note 8 to the Company's
Consolidated Financial Statements) having a value equal to $15 million, subject
to adjustment based on certain changes in Page America's working capital and
service revenues. Under the terms of the Page America Agreement, the Company has
retained the option to substitute cash at closing for all or a portion of the
equity securities that are part of the consideration. Consummation of the Page
America acquisition is subject to a number of conditions including, but not
limited to, receipt of all necessary regulatory approvals and approval by the
Page America stockholders. There can be no assurance that such approvals will be
obtained. The pending transaction, if consummated, will be accounted for as a
purchase for financial reporting purposes. The Company expects to finance the
cash portion of the purchase price with borrowings under its credit facility by
leveraging Page America's operating cash flow as permitted under the agreement
governing the New Credit Facility.
    
 
ADDITIONAL FACTORS AFFECTING FUTURE OPERATING RESULTS AND FINANCIAL CONDITION
 
     The ability of the Company to meet its debt service and other obligations
will be dependent upon the future performance of the Company and its cash flows
from operations, which will be subject to financial, business and other factors,
certain of which are beyond its control, such as prevailing economic conditions.
Management believes that funds generated from the Company's operations and funds
available under its credit facility will be sufficient to meet projected capital
expenditures and debt service requirements and to fund the Company's operations
for the foreseeable future. Although management has no further obligation to do
so (other than Page America discussed above), it plans to continue to expand its
geographic service areas
 
                                       30
<PAGE>   32
 
through internal growth and will continue to evaluate potential strategic
acquisition targets in the future which may result in substantial capital
requirements for which additional financing may be required. No assurance can be
given that such additional financing would be available on terms satisfactory to
the Company. Additionally, the following important factors, among others, could
cause the Company's operating results and financial condition to differ
materially from those indicated or suggested by forward looking statements made
in this annual report.
 
  Substantial Indebtedness
 
     At December 31, 1996, the Company had outstanding approximately $327.8
million in long term debt consisting of bank loans, senior subordinated notes,
mortgage indebtedness and capital leases, and expects to incur additional
indebtedness in connection with the Page America acquisition. The Company
increased its borrowings outstanding under its credit facility by $10.0 million
in January 1997. Additionally, the Company expects to incur additional
indebtedness (in the form of draws under the Company's senior secured credit
facility) to meet working capital needs and other purposes. This substantial
indebtedness, along with the net losses and working capital deficits sustained
by the Company in recent periods, will have consequences for the Company,
including the following: (i) the ability of the Company to obtain additional
financing for working capital, capital expenditures, debt service requirements
or other purposes may be impaired; (ii) a substantial portion of the Company's
cash flow from operations will be required to be dedicated to the payment of the
Company's interest expense; (iii) indebtedness under the New Credit Facility
bears interest at floating rates, which will cause the Company to be vulnerable
to increases in interest rates; (iv) the Company may be more highly leveraged
than companies with which it competes, which may place it at a competitive
disadvantage; and (v) the Company may be more vulnerable in the event of a
downturn in its business or in general economic conditions. In addition, the
ability of the Company to access borrowings under its credit facility and to
meet its debt service and other obligations (including compliance with financial
covenants) will be dependent upon the future performance of the Company and its
cash flows from operations, which will be subject to financial, business and
other factors, certain of which are beyond its control, such as prevailing
economic conditions. No assurance can be given that, in the event the Company
were to require additional financing, such additional financing would be
available on terms permitted by agreements relating to existing indebtedness or
otherwise satisfactory to Metrocall.
 
  Possible Impact of Competition and Technological Change
 
   
     The Company faces competition from other paging companies in all markets in
which it operates. The wireless communications industry is a highly competitive
industry, with price being one of the primary means of differentiation among
providers of numeric messaging services which account for the substantial
majority of the Company's revenues. Companies in the industry also compete on
the basis of coverage area, enhanced services, transmission quality, system
reliability and customer service. Certain of Metrocall's competitors possess
greater financial, technical, marketing and other resources than Metrocall. In
addition, other entities offering wireless two-way communications technology,
including cellular telephone, specialized mobile radio services and personal
communications services, compete with the paging services provided by Metrocall.
There can be no assurance that additional competitors will not enter markets
served by Metrocall or that Metrocall will be able to compete successfully. In
this regard, certain long distance carriers have or have announced their
intention to market paging services jointly with other telecommunications
services.
    
 
     The wireless communications industry is characterized by rapid
technological change. Future technological advances in the wireless
communications industry could create new services or products competitive with
the paging and wireless messaging services provided or to be developed by
Metrocall. Recent and proposed regulatory changes by the Federal Communications
Commission ("FCC") are aimed at encouraging such services and products.
 
     In particular, in 1994, the FCC began auctioning licenses for new personal
communications services ("PCS"). The FCC's rules also provide for the private
use of PCS spectrum on an unlicensed basis. PCS will involve a network of small,
low-powered transceivers placed throughout a neighborhood, business complex,
community or metropolitan area to provide customers with mobile voice and data
communications. There are
 
                                       31
<PAGE>   33
 
two types of PCS, narrowband and broadband. Narrowband PCS is expected to
provide enhanced or advanced paging and messaging capabilities, such as
"acknowledgment paging" or "talk-back" paging. Several PCS systems are currently
operational. Additionally, other existing or prospective radio services have
potential to compete with Metrocall. For example, the FCC has authorized
non-geostationary mobile satellite service systems in several frequency bands,
and has initiated proceedings to consider making additional licenses in some of
those bands available. Licensees of those satellite services (some of whom have
already launched satellites) are permitted to offer signaling and other mobile
services that could compete with terrestrial paging companies. A recent FCC
decision will allow land mobile licensees in the 220-222 MHz band to offer
commercial paging services. The FCC has also initiated a rule making proceeding
proposing to allow Multiple Address Systems, a fixed microwave service in
various 900 MHz frequency bands, to offer mobile services. Any of these services
may compete directly or indirectly with Metrocall.
 
     Moreover, changes in technology could lower the cost of competitive
services and products to a level where Metrocall's services and products would
become less competitive or to where Metrocall would be required to reduce the
prices of its services and products. There can be no assurance that Metrocall
will be able to develop or introduce new services and products to remain
competitive or that Metrocall will not be adversely affected in the event of
such technological developments.
 
     Technological changes also may affect the value of the pagers owned by
Metrocall and leased to its subscribers. If Metrocall's subscribers requested
more technologically advanced pagers, Metrocall could incur additional capital
expenditures if it were required to replace pagers to its subscribers.
 
  History of Net Losses
 
     Metrocall has sustained net losses of $2.4 million, $20.1 million and $49.1
million for the years ended December 31, 1994, 1995 and 1996. No assurance can
be given that losses can be reversed in the future. In addition, at December 31,
1996, Metrocall's accumulated deficit was $96.8 million and Metrocall had a
deficit in working capital of $7.3 million. Metrocall's business requires
substantial funds for capital expenditures and acquisitions that result in
significant depreciation and amortization charges. Additionally, substantial
levels of borrowing, which will result in significant interest expense, are
expected to be outstanding in the foreseeable future. Accordingly, net losses
are expected to continue to be incurred in the future. There can be no assurance
that Metrocall will be able to operate profitably at any time in the future.
 
  Litigation
 
     In April 1996, the Company entered into an agreement to purchase certain of
the assets of Source One Wireless, Inc. ("Source One") and placed $1 million
cash in escrow. On June 26, 1996, the Company advised Source One that Source One
had failed to meet certain conditions to completion of the transaction and
terminated the agreement. On September 20, 1996, Source One filed an action in
the Circuit Court of Cook County, Illinois claiming that the Company had
breached the agreement and seeking specific performance of the purchase
agreement or unspecified damages in excess of $80 million. The Company intends
to vigorously defend the claims in this action and believes it has meritorious
defenses to this action.
 
  Subscriber Turnover
 
   
     The results of operations of paging service providers, such as Metrocall,
can be significantly affected by subscriber cancellations and by subscribers who
switch their service to other carriers. Metrocall's average monthly subscriber
turnover rate for the year ended December 31, 1996 was approximately 2.1%. In
order to realize net growth in subscribers, disconnected subscribers must be
replaced and new subscribers must be added. The sales and marketing costs
associated with attracting new subscribers are substantial relative to the costs
of providing service to existing customers. Because Metrocall's business is
characterized by high fixed costs, disconnections directly and adversely affect
Metrocall's results of operations. An increase in its subscriber cancellation
rate may adversely affect Metrocall's results of operations.
    
 
                                       32
<PAGE>   34
 
  Potential for Change in Regulatory Environment
 
     Metrocall's paging operations are subject to regulation by the FCC and, to
a lesser extent, by various state regulatory agencies. There can be no assurance
that those agencies will not adopt regulations or take actions that would have a
material adverse effect on the business of Metrocall. Changes in regulation of
Metrocall's paging business or the allocation of radio spectrum for services
that compete with Metrocall's business could adversely affect Metrocall's
results of operations. For example, the FCC is currently engaged in a rule
making proceeding whereby it proposes to issue paging licenses on a wide-area
basis by competitive bidding. Although, Metrocall believes that the proposed
rule changes may simplify Metrocall's regulatory compliance burdens,
particularly regarding adding or relocating transmitter sites, those rule
changes may also increase Metrocall's costs of obtaining paging licenses.
 
  Intangible Assets
 
     Intangible assets, net of accumulated amortization, increased from
approximately $129.1 million in 1995 to approximately $452.6 million in 1996
primarily as a result of the Company's 1996 acquisitions of Parkway, Satellite,
Message Network and A+ Network. At December 31, 1996, the Company's total assets
of approximately $651.5 million included net intangible assets of approximately
$452.6 million. Intangible assets include state certificates and FCC licenses,
customer lists, debt financing costs, goodwill and certain other intangibles.
The Company will record, for financial reporting purposes, additional intangible
assets in connection with its acquisition of the assets of Page America in 1997.
Long-lived assets and identifiable intangibles to be held and used are reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount should be addressed. Impairment is measured by comparing the
book value to the estimated undiscounted future cash flows expected to result
from use of the assets and their eventual disposition. The Company's estimates
of anticipated gross revenues, the remaining estimated lives of tangible and
intangible assets, or both, could be reduced significantly in the future due to
changes in technology, regulation, available financing and competitive pressures
in any of the Company's individual markets. As a result, the carrying amount of
long-lived assets and intangible assets including goodwill could be reduced
materially in the future.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Metrocall, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Metrocall,
Inc., and subsidiaries as of December 31, 1995 and 1996, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1996. 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 an 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 Metrocall, Inc., and
subsidiaries as of December 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

     On July 16, 1996, the Company acquired Parkway Paging, Inc. of Plano, Texas
("Parkway"). On August 30, 1996, the Company acquired substantially all the
assets of Satellite Paging of Fairfield, New Jersey and Message Network of Boca
Raton, Florida (together, "Satellite"). On November 15, 1996, the Company
acquired A+ Network, Inc. of Pensacola, Florida ("A+ Network"). The Company
acquired the operations of A+ Network through a merger of A+ Network with and
into Metrocall. On August 31, and November 29, 1994, Metrocall acquired
FirstPAGE USA, Inc. ("FirstPAGE") and MetroPaging Inc. ("MetroPaging," formerly
AllCity Paging, Inc.), respectively. The consolidated statements of operations
include the results of acquired companies since their respective acquisition
dates.
 
  Risks and Other Important Factors
 
     The Company sustained net losses of $2.4 million, $20.1 million, and $49.1
million for the years ended December 31, 1994, 1995 and 1996, respectively. The
Company's loss from operations for the year ended December 31, 1996 was $25.4
million. In addition, at December 31, 1996, the Company has an accumulated
deficit of $96.8 million and a deficit in working capital of $7.3 million. The
Company's losses from operations and its net losses are expected to continue for
additional periods in the future. There can be no assurance that the Company's
operations will become profitable.
 
     The Company's operations require the availability of substantial funds to
finance the maintenance and growth of its existing paging operations and
customer base, development and construction of future wireless communications
networks, expansion into new markets, and the acquisition of other wireless
communication companies. At December 31, 1996, the Company had incurred
approximately $328 million in long-term debt and capital leases. Amounts
available under the Company's credit facility are subject to certain financial
covenants and other restrictions such that as of January 1, 1997, approximately
$46.5 million of additional borrowings were available to the Company under its
credit facility. The Company's ability to borrow additional amounts in the
future is dependent on its ability to comply with the provisions of its credit
facility. On January 14, 1997, the Company increased borrowings outstanding
under its credit facility by $10.0 million.
 
     The Company is also subject to certain additional risks and uncertainties
including changes in technology, business integration, competition and
regulation (see also Notes 2 and 14).
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
   
     In addition to Metrocall, the accompanying consolidated financial
statements include the accounts of Metrocall's 61% interest in Beacon Peak
Associates Ltd. ("Beacon Peak"), Metrocall's 20% interest in Beacon
Communications Associates ("Beacon Communications"), and Metrocall of Virginia,
Inc. and Metrocall, USA, Inc., nonoperating wholly owned subsidiaries that hold
certain of the Company's regulatory licenses issued by the Federal
Communications Commission (the "FCC").

2.  SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

     Beacon Communications owns the building that is the Company's headquarters.
Since Beacon Communications' debt related to the building is guaranteed by the
Company's lease (expiring 2008) and because the Company has made the only
substantive investment in Beacon Communications, the accounts of Beacon
Communications have been consolidated in the accompanying financial statements.
In 2008, the Company and Beacon Communications could agree upon alternate
arrangements that could result in an accounting treatment other than
consolidation. Beacon Peak owns land, adjacent to the Beacon Communications
building, which is valued at cost.
 
     The minority interest in Beacon Peak is $501,000 and $499,000 as of
December 31, 1995 and 1996, respectively. Beacon Communications has a
partnership deficit as of both December 31, 1995 and 1996, respectively, and
accordingly, the minority interest is not recognized in the accompanying
consolidated financial statements.
 
     All significant intercompany transactions have been eliminated in
consolidation.
 
  Use of Estimates in the Preparation of Financial Statements
 
     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.
 
  Revenue Recognition
 
     The Company recognizes revenue under service, rental and maintenance
agreements with customers as the related services are performed. The Company
leases (as lessor) radio pagers under operating leases. Substantially all the
leases are on a month-to-month basis. Advance billings for services are deferred
and recognized as revenue when earned. Sales of equipment are recognized upon
delivery.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include short-term, highly liquid investments
purchased with original maturities of three months or less.
 
  Property and Equipment
 
     Property and equipment are carried at cost. Depreciation is computed using
the straight-line method over the following estimated useful lives.

     Purchases of property and equipment in the accompanying consolidated
statements of cash flows are reflected net of the net book value of products
sold to approximate the net addition to subscriber equipment.
 
     The Company currently purchases a significant amount of its subscriber
paging equipment from one supplier. Although there are other manufacturers of
similar subscriber paging equipment, the inability of this supplier to provide
equipment required by the Company could result in a decrease of pager placements
and decline in sales, which could adversely affect operating results.

</TABLE>
 
     Debt financing costs represent fees and other costs incurred in connection
with the issuance of long-term debt. These costs are amortized to interest
expense over the term of the related debt using the effective interest rate
method.
 
  Long-Lived Assets
 
     Long-lived assets and identifiable intangibles to be held and used are
reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount should be addressed. Impairment is measured by
comparing the book value to the estimated undiscounted future cash flows
expected to result from use of the assets and their eventual disposition. At
December 31, 1996, the market value of the Company's Common Stock was $5.016 per
share and the net book value was $6.78 per share. However, the Company has
determined that there has been no permanent impairment in the carrying value of
long-lived assets reflected in the accompanying balance sheet.
 
     Effective July 1, 1996, the Company changed the estimated useful lives of
certain intangibles acquired in 1994, including goodwill and regulatory licenses
issued by the FCC recorded in the acquisitions of FirstPAGE USA, Inc., and
MetroPaging, Inc., from 40 years to 15 years for goodwill and from 40 years to
25 years for FCC licenses. The impact of these changes was to increase
amortization expense for the year ended December 31, 1996, by approximately $1.3
million.
 
  Loss Per Common Share Attributable to Common Stockholders
 
     Loss per common share attributable to common stockholders for the years
ended December 31, 1994, 1995 and 1996, is based upon the weighted-average
number of common equivalent shares outstanding during the period. The effect of
outstanding options and warrants on net loss per share for the years ended
December 31, 1994, 1995, and 1996, is not included because such options and
warrants would be antidilutive (see Note 8).

3.  ACQUISITIONS
 
  1994 Acquisitions
 
     On August 31, 1994, the Company acquired 100% of the outstanding common
stock of FirstPAGE by means of a merger of FPGE Acquisition Corp., Inc.,
formerly a wholly owned subsidiary of Metrocall formed to effect the FirstPAGE
merger, with and into FirstPAGE, leaving FirstPAGE a wholly owned subsidiary of
the Company. The acquisition was financed through the issuance of 2,869,190
shares of the Company's Common Stock and options to purchase 47,387 shares of
the Company's Common Stock and an assumption of substantially all liabilities of
FirstPAGE.
 
     On November 29, 1994, the Company acquired 100% of the outstanding common
stock of MetroPaging by means of a merger of ACPI Acquisition Corporation,
formerly a wholly owned subsidiary of Metrocall formed to effect the MetroPaging
merger, with and into MetroPaging, leaving MetroPaging a wholly owned subsidiary
of the Company. The acquisition was financed through the issuance of 630,645
shares of the Company's Common Stock and an assumption of substantially all
liabilities of MetroPaging.
 
     In May 1995, the total number of shares of Metrocall Common Stock issued to
MetroPaging stockholders was adjusted, reducing the total purchase price by
approximately $105,000. This adjustment reduced goodwill recorded as a result of
the acquisition.
 
  Parkway Paging, Inc.
 
     On July 16, 1996, the Company acquired all the outstanding common stock of
Parkway for cash and the assumption of certain long-term obligations together
totaling approximately $28.0 million. The acquisition was financed through
drawings on the Company's credit facility.
 
  Satellite Paging and Message Network
 
     On August 30, 1996, the Company acquired substantially all the assets of
Satellite for cash, the assumption of certain liabilities and the issuance of
shares of the Company's Common Stock. The total number of shares to be issued
under the terms of the agreement has not been finalized and will fluctuate based
on the Company's stock price and final capital expenditures and working capital
amounts. As of December 31, 1996, the Company had issued 1,771,869 shares of
Metrocall Common Stock. The cash paid in the acquisition was financed through
drawings on the Company's credit facility.
 
  A+ Network, Inc.
 
     On November 15, 1996, the Company completed its merger with A+ Network of
Pensacola, Florida pursuant to an Agreement and Plan of Merger dated May 16,
1996. The total purchase price was approximately $286.4 million, consisting of
approximately 8.1 million shares of the Company's Common Stock valued at
approximately $42.6 million ($5.25 per share), 8.1 million indexed Variable
Common Rights ("VCRs"), approximately $91.8 million paid in a cash tender offer
completed in July 1996, indebtedness refinanced under the Company's existing
credit facility of approximately $122.5 million, and other assumed indebtedness,
estimated future liabilities and transaction fees, but excluding deferred income
tax liabilities of approximately $57.4 million recorded in the merger.

3.  ACQUISITIONS -- (CONTINUED)

     Prior to November 15, 1996, the Company acquired approximately 40% of the
A+ Network common stock outstanding in a cash tender offer completed in July
1996. For financial reporting purposes, the Company accounted for its investment
in A+ Network under the equity method. As such, the Company recorded its share
of A+ Network's net loss of approximately $4.1 million through November 15,
1996, which has been classified as Other Expense in the accompanying statement
of operations for the year ended December 31, 1996.
 
     In addition, the Company repurchased approximately 40% of all options
outstanding to acquire A+ Network common stock for $13.98 per share or
approximately $4.0 million including related payroll taxes. The remaining A+
Network options, with an exercise price of $6.04 per common share, were assumed
by the Company and exchanged for Metrocall options (see Note 8).
 
     Cash payments made in the merger were financed through the Company's credit
facility.
 
     All of the Company's acquisitions have been accounted for as purchases for
financial reporting purposes. The purchase prices for the 1994 acquisitions and
the 1996 acquisitions of Parkway, Satellite and A+ Network transactions have
been allocated as follows (in thousands):

     On October 2, 1995, the Company completed a public offering of $150.0
million Senior Subordinated Notes (the "Notes"), due 2007, bearing interest at
10.375% per annum, payable semiannually on April 1 and October 1, commencing
April 1, 1996. The Notes are general unsecured obligations subordinated in right
to the Company's existing long-term debt and other senior obligations, as
defined. After underwriting discounts, commissions and other professional fees,
net proceeds from the Notes were approximately $145.0 million.
 
     The Company incurred total loan origination fees and other direct financing
costs of approximately $5.0 million, which will be recognized as interest
expense over the term of the Notes. Debt financing costs are included in
intangible assets in the accompanying consolidated balance sheets as of December

     In connection with the merger with A+ Network, the Company offered to

due 2005 (the "A+ Notes") for $1,005 per $1,000 principal amount plus accrued
and unpaid interest (the "Offer"). Concurrent with the Offer, the Company
solicited consents to amend the indenture governing the A+ Notes to eliminate
substantially all restrictive covenants and certain related events of default
contained therein in exchange for a payment of $5.00 for each $1,000 principal
amount of the A+ Notes. Of the total outstanding, approximately $122.5 million
were validly tendered and retired. Tendered notes were financed under the
Company's credit facility. Additionally, sufficient consents were received so
that substantially all restrictive covenants and related events of default were
eliminated. The principal balance of the notes untendered, $2.5 million, has
been assumed by the Company. Interest on the notes is payable semi-annually in
May and November. The Company incurred fees of approximately $3.7 million in
connection with the tender and consent process which has been recorded as an
extraordinary item for the year ended December 31, 1996.
 
     The A+ Notes may be redeemed at the Company's option after November 1,

  Capital Lease Obligations
 
     In April 1994, the Company entered into a lease agreement (the "Lease
Agreement") for additional office space. The Lease Agreement required initial
minimum monthly rents of $37,500. In January 1997, the Company acquired
additional office space under the Lease Agreement. Initial monthly payments will
increase to approximately $68,000 beginning January 1997. The Lease Agreement
will continue to be treated as a capital lease for financial reporting purposes.
The Lease Agreement continues for an initial period of ten years

and may be renewed for two additional five-year periods. In connection with the
Lease Agreement, the Company entered into an Option and Purchase Agreement (the
"Purchase Agreement"), which gives the Company an option to acquire a 51%
interest in the property housing the office space, discussed above. The Company
may exercise the option from January 2, 1995, through December 31, 1997. At the
time the option is exercised, the Company, along with the owners of the
remaining 49% interest in the property, will contribute the property to a
limited partnership for which the Company will serve as general partner and
receive a 51% equity interest. When, if ever, the Company exercises the purchase
option to the Purchase Agreement, the purchase price will be approximately $2.9
million.
 
     On July 1, 1996, the Company entered into a lease agreement for certain
computer equipment. The lease agreement requires quarterly rental payments of
approximately $115,000 for a period of three years. This lease agreement has
been accounted for as a capital lease for financial reporting purposes.

  New Credit Facility
 
     On September 20, 1996, the Company entered into an agreement to amend and
restate the loan agreement governing the Company's existing credit facility.
Subject to certain conditions set forth in the new agreement, the Company may
borrow up to $350,000,000 under two loan facilities. The first facility
("Facility A") is a $225,000,000 reducing revolving credit facility and the
second ("Facility B") is a $125,000,000 reducing credit facility (together
Facility A and Facility B are referred to as the "New Credit Facility"). The New
Credit Facility has a term of eight years and is secured by substantially all
the assets of the Company. Required quarterly principal repayments begin on
March 31, 2000 and continue through December 31, 2004. At December 31, 1996, a
total of $169,904,000 was outstanding under the New Credit Facility. On January
14, 1997, the Company increased its borrowings outstanding under the New Credit
Facility by $10,000,000.
 
     The New Credit Facility contains various covenants that, among other
restrictions, require the Company to maintain certain financial ratios,
including total debt to annualized operating cash flow (not to exceed 6.0 to 1.0
from January 1, 1997 to December 31, 1997, and declining thereafter), senior
debt to annualized operating cash flow, annualized operating cash flow to pro
forma debt service, total sources of cash to total uses of cash, and operating
cash flow to interest expense (in each case, as such terms are defined in the
agreement relating to the New Credit Facility). The New Credit Facility also
requires the Company to raise additional equity (approximately $10,000,000) if
its ratio of cash flow to interest expense is less than 2.0 to 1.0 for the
quarter ended June 30, 1997. The covenants also limit additional indebtedness
and future mergers and acquisitions (other than the pending transaction
discussed in Note 14) without the approval of the lenders and restrict the
payment of cash dividends and other stockholders distributions by Metrocall
during the term of the

agreement. The New Credit Facility also prohibits certain changes in ownership
control of Metrocall, as defined.
 
     Under the New Credit Facility, the Company may designate all or any portion
of the borrowings outstanding as either a floating base rate advance or a
Eurodollar rate advance with an applicable margin that ranges from 0.0% to
1.750% for base rate advances and 0.875% to 2.750% for Eurodollar rate advances.
The predefined margins will be based upon the level of indebtedness outstanding
relative to annualized cash flow, as defined in the agreement relating to the
New Credit Facility. Commitment fees of 0.25% to 0.375% per year (depending on
the level of Metrocall's indebtedness outstanding to annualized cash flow) will
be charged on the average unused balance and will be charged to interest expense
as incurred. Pursuant to the terms of the New Credit Facility, Metrocall must
obtain and maintain interest rate protection on at least 50% of Metrocall's
outstanding debt; all fixed rate debt, including the 10 3/8% Senior Subordinated
Notes due 2007, will count against this requirement. At December 31, 1996, the
obligation to obtain interest rate protection had not commenced and accordingly
the Company had not entered into any interest rate protection agreements.
 
     The Company incurred loan origination fees and direct financing costs in
connection with the New Credit Facility of approximately $4.5 million which will
be amortized and charged to interest expense over the term of the New Credit
Facility.
 
     The weighted-average balances outstanding under all credit facilities
outstanding for the years ended December 31, 1994, 1995 and 1996, were
approximately $35,818,000, $108,222,000 and $39,902,000, respectively. The
highest outstanding borrowings under these facilities for the years ended
December 31, 1994, 1995 and 1996, were approximately $100,320,000, $113,320,000
and $169,904,000, respectively. For the years ended December 31, 1994, 1995 and
1996, interest expense relating to these facilities was approximately
$3,458,000, $7,630,000 and $3,737,000, respectively, at weighted-average
interest rates of 9.7%, 7.0% and 9.4%, respectively. The effective interest
rates as of December 31, 1995 and 1996 were 8.5% and 8.0%, respectively.
 
  Former Credit Facility
 
     On August 31, 1994, the Company entered into a secured credit agreement
(the "Agreement," as amended) with a group of lenders (the "Lenders") for $175.0
million, consisting of a seven-year $100.0 million reducing revolver and a
seven-year $75.0 million revolving credit and term loan (collectively, the
"Facility"). Borrowings under the Facility were used to refinance existing
indebtedness (under its former credit agreement, discussed below) and finance
the acquisitions of FirstPAGE and MetroPaging (see Note 3), as well as capital
expenditures and general corporate requirements. On September 20, 1996, the
Company amended and restated the Agreement with an agreement for the New Credit
Facility discussed above.
 
   
     Upon completion of the Notes offering, discussed above, the Company repaid
all amounts outstanding under the Facility and terminated the interest rate swap
agreements. Accordingly, upon repayment, the Company recorded an extraordinary
charge to write-off then existing unamortized debt financing costs of $2.7
million in the year ended December 31, 1995. The Company also incurred breakage
fees of approximately $1.7 million associated with the termination of the
interest rate swap agreements which have been recorded as interest and other
income (expense) in the 1995 consolidated statement of operations.
    
 
  Prior Credit Facility
 
     In November 1993, the Company entered into a revolving credit agreement
("Credit Facility") with a group of banks. The Credit Facility provided for an
$85.0 million secured seven-year revolving credit facility.

Borrowings under the Credit Facility were used to refinance balances outstanding
under a previous credit agreement. On August 31, 1994, the balances outstanding
under the Credit Facility ($12.5 million) were refinanced with the Facility
discussed above.
 
     The Company incurred loan origination fees and direct financing costs in
connection with the revolving credit agreement. In connection with the repayment
of indebtedness outstanding under its then existing credit facility, the Company
recognized an extraordinary charge to write-off existing unamortized debt
financing costs, net of income tax benefit of $36,000, of approximately $1.3
million in 1994.
 
  Promissory Note Payable
 
     The Company assumed indebtedness in the A+ Network merger of approximately
$627,000. The promissory note is payable as consideration for an acquisition
completed by A+ Network in May 1996. The promissory note bears interest at 7.5%
with monthly principal and interest payments of $8,333 through June 2005.

8.  STOCK AND STOCK RIGHTS
 
     The authorized capital stock of Metrocall consists of 33,500,000 shares of
common stock, par value $0.01 per share ("Metrocall Common Stock" or "Common
Stock") and 1,000,000 shares of preferred stock, par value $0.01 per share
("Preferred Stock"), of which 810,000 shares have been designated as Series A
Convertible Preferred Stock ("Series A Preferred Stock"), 9,000 shares will be
designated Series B Convertible Preferred Stock ("Series B Preferred Stock") and
4,000 shares will be designated as Common Stock Equivalent Preferred Stock ("CSE
Preferred Stock").
 
  Common Stock
 
     On September 27, 1995, the Company completed a secondary public offering of
4.0 million shares of the Company's Common Stock (the "Secondary Offering"), at
$28.25 per share. After underwriting discounts, commissions and other
professional fees, net proceeds from the Secondary Offering were approximately
$107.0 million.

8.  STOCK AND STOCK RIGHTS -- (CONTINUED)

     At the Company's annual meeting of the Company's stockholders in May 1996,
the Company's stockholders approved an increase in the authorized number of
shares of Common Stock from 20,000,000 to 26,000,000. Additionally, at a special
meeting of the Company's stockholders in November 1996, the stockholders
increased the authorized number of shares of Common Stock from 26,000,000 to
33,500,000. The Company intends to seek approval from its stockholders at its
annual meeting in May 1997 to increase the number of authorized shares of Common
Stock to 60,000,000.
 
     Because the Company holds licenses from the FCC, no more than 20 percent of
the Company's Common Stock may, in the aggregate, be owned directly or
indirectly, or voted by a foreign government, a foreign corporation, or resident
of a foreign country. The Company's amended and restated certificate of
incorporation permits the redemption of the Company's Common Stock from
stockholders, where necessary, to protect the Company's regulatory licenses.
Such stock may be redeemed at fair market value or if the stock was purchased
within one year of such redemption, at the lesser of fair market value or such
holder's purchase price.
 
  Series A Preferred Stock
 
     The Board of Directors has designated 810,000 shares of Preferred Stock as
Series A Preferred Stock. On November 15, 1996, the Company issued 159,600
shares of Series A Preferred Stock, together with the warrants discussed below,
for $250 per share or $39.9 million. The Company incurred fees of approximately
$1.6 million. Net proceeds from the Series A Preferred Stock ($38.3 million)
were used to reduce outstanding bank indebtedness ($25 million) and to fund
existing working capital requirements ($13.3 million). Each share of Series A
Preferred Stock has a stated value of $250 per share and has a liquidation
preference over shares of the Company's Common Stock equal to the stated value.
The Series A Preferred Stock carries a dividend of 14% of the stated value per
year, payable semiannually in cash or in additional shares of Series A Preferred
Stock, at the Company's option. Upon the occurrence of a triggering event, as
defined in the certificate of designation for Series A Preferred Stock, and so
long as the triggering event continues, the dividend rate increases to 16% per
year. Triggering events include, among other things, (i) the failure of the
stockholders of Metrocall to approve an increase in the number of authorized
shares of Common Stock to at least 50,000,000 on or prior to June 1, 1997, (ii)
the Company issues or incurs indebtedness or equity securities senior with
respect to payment of dividends or distributions on liquidation or redemption to
the Series A Preferred Stock in violation of limitations set forth in the
certificate of designation, and (iii) default on the payment of indebtedness in
an amount of $5,000,000 or more. So long as a triggering event described in (i)
above is continuing, dividends must be paid in cash to the extent permitted by
the terms of agreements relating to the Company's debt. At December 31, 1996,
accrued but unpaid dividends were approximately $698,000.
 
     Holders of Series A Preferred Stock have the right, beginning five years
from the date of issuance, to convert their Series A Preferred Stock (including
shares issued as dividends) into shares of Metrocall Common Stock based on the
market price of the Common Stock at the time of conversion. Series A Preferred
Stock may, at the holders' option, be converted sooner upon a change of control
of Metrocall, as defined in the certificate of designation. The Series A
Preferred Stock must be redeemed on November 15, 2008, for an amount equal to
the stated value plus accrued and unpaid dividends.
 
   
     The Series A Preferred Stock may be redeemed by the Company in whole or in
part (subject to certain minimums) beginning November 15, 1999. Prior to then,
the Series A Preferred Stock may be redeemed by the Company in whole in
connection with a sale of the Company (as described in the Series A Preferred
Stock certificate of designation) unless the holders have exercised their rights
to convert to Metrocall Common Stock in connection with the transaction. The
redemption price prior to November 15, 2001, is equal to the stated value of the
shares of Series A Preferred Stock, plus accrued and unpaid dividends, and a
redemption

premium, as defined. After November 15, 2001, the Series A Preferred Stock may
be redeemed for the stated value of $250 per share, without premium.
 
     Holders of Series A Preferred Stock have the right to elect two members to
the Company's Board of Directors. If a triggering event has occurred and is
continuing, the holders of Series A Preferred Stock have the right to elect
additional directors so that directors elected by such holders shall constitute
no less than 40% of the members of the Board of Directors. The Company is
required to obtain the approval of the holders of not less than 75% of the
Series A Preferred Stock before undertaking (i) any changes in the Metrocall
Certificate of Incorporation and Bylaws that adversely affect the rights of
holders of the Series A Preferred Stock, (ii) a liquidation, winding up or
dissolution of the Company or the purchase of shares of capital stock of
Metrocall from holders of over 5% of the issued and outstanding voting
securities, (iii) any payment of dividends on or redemption of Metrocall Common
Stock; or (iv) issuance of any additional shares of Series A Preferred Stock
(except in payment of dividends) or any shares of capital stock having
preferences on liquidation or dividends ranking equally to the Series A
Preferred Stock. The Company is also required to obtain approval of holders of
not less than a majority of the issued and outstanding Series A Preferred Stock
before undertaking (i) any acquisition involving consideration having a value
equal to or greater than 50% of the market capitalization of the Company or (ii)
any sale of the Company unless Metrocall redeems the Series A Preferred Stock.
 
  Series B Preferred Stock
 
     In connection with the Page America transaction (see Note 14), the Board of
Directors has authorized the designation of 9,000 shares of Preferred Stock as
Series B Preferred Stock. Each share of Series B Preferred Stock will have a
stated value of $10,000 per share and a liquidation preference, which is junior
to the Series A Preferred Stock but senior to the shares of Metrocall Common
Stock, equal to its stated value. The Series B Preferred Stock will carry a
dividend of 14% of the stated value per year, payable semiannually in cash or in
additional shares of Series B Preferred Stock, at the Company's option. The
Company has agreed to issue 1,500 shares of Series B Preferred Stock pursuant to
the Amended Page America Agreement (see Note 14).
 
     Subject to the approval of the conversion rights by holders of the
Metrocall Common Stock, beginning on September 1, 1997, and quarterly
thereafter, the holders of Series B Preferred Stock will have the right to
convert up to 25% of the number of Series B Preferred Stock initially issued
(plus shares of Series B Preferred Stock issued as dividends on such shares, and
as dividends on such dividends) into shares of Metrocall Common Stock at the
current market value of the Common Stock, as defined.
 
     The Series B Preferred Stock must be redeemed on the twelfth anniversary of
the initial issuance for an amount equal to the stated value, plus accrued and
unpaid dividends. The Series B Preferred Stock may also be redeemed by the
Company in whole or in part at any time for an amount equal to the stated value
of the sales to be redeemed plus accrued and unpaid dividends. If Metrocall
elects to redeem Series B Preferred Stock, the holders thereof will have the
right to convert any Series B Preferred stock that was then convertible into
Metrocall Common Stock within 15 business days after receipt of notice of
redemption.
 
     The Company is required to obtain the approval of holders of a majority of
the issued and outstanding Series B Preferred Stock before undertaking (i) any
changes in the Metrocall Certificate of Incorporation and Bylaws that adversely
affect the rights of the holders of Series B Preferred Stock and (ii) any
changes in the Series B Certificate of Designation. The Series B Preferred Stock
also contains restrictions on the ability of Metrocall to incur any debt or
issue securities (other than the Series A Preferred Stock) that are senior to
the Series B Preferred Stock.

8.  STOCK AND STOCK RIGHTS -- (CONTINUED)

  Common Stock Equivalent Preferred Stock
 
     In connection with the Page America transaction (see Note 14), the Board of
Directors has authorized the designation of 4,000 shares of Preferred Stock as
Common Stock Equivalent Preferred Stock. Pursuant to the Amended Page America
Agreement (see Note 14), Page America may receive CSE Preferred Stock. Each
share of CSE Preferred Stock will equal .001 shares of a series of preferred
stock. Each share of CSE Preferred Stock will have one vote per share on all
matters submitted to a vote of holders of Metrocall Common Stock, will be
entitled to receive a dividend equal to any dividend declared and paid with
respect to the Metrocall Common Stock, will have a liquidation preference equal
to that of the Metrocall Common Stock and will be automatically converted into
Metrocall Common Stock when sufficient shares have been approved by the
Company's stockholders. In the event sufficient shares of Metrocall Common Stock
are not available and the Company's stockholders have not approved an increase
in the authorized number of shares of Metrocall Common Stock to 60,000,000 by
June 1, 1997, the CSE Preferred Stock will be automatically converted into that
number of shares of Series B Preferred Stock equal to the total share value of
the CSE Preferred Stock (as of the closing of the Page America transaction)
divided by $10,000.
 
  Warrants
 
     In connection with the issuance of the Series A Preferred Stock, discussed
above, the Company issued on November 15, 1996, warrants to purchase Metrocall
Common Stock. Each warrant represents the right of the holder to purchase 18.266
shares of Metrocall Common Stock or an aggregate of 2,915,254 shares of
Metrocall Common Stock. The exercise price per share is $7.40. The warrants
expire November 15, 2001.
 
     The total value allocated to the warrants for financial reporting purposes,
$7.9 million or $2.70 per share, will be accreted over the term of the Series A
Preferred Stock as preferred dividends.
 
  Variable Common Rights
 
     As part of the merger consideration, stockholders of A+ Network received
VCRs equal to the number of shares of Metrocall Common Stock they received in
the merger. Each VCR entitles the holder to receive a payment of up to $5.00 in
either the Company's Common Stock or cash, at the Company's option, if the
market value, as defined, of the Company's Common Stock at November 15, 1997, is
less than a specified target price. The target price will be adjusted downward,
but not upward, based on changes in an index composed of the average closing bid
prices of three other companies in the paging industry since the announcement of
the merger. If changes in the index cause the target price to be lower than a
floor price of $16.10 (which is not indexed and therefore not adjusted
downward), the VCR payment will be zero without regard to the trading value of
the Company's Common Stock. At November 15, 1996, the date the merger was
completed, the target price was estimated to be approximately $5.97 per share.
For financial reporting purposes, no value has been assigned to the VCRs. As of
December 31, 1996, the target price was below the fixed floor price of $16.10
per share.
 
  Stock Option Plans
 
     In 1993, the Company adopted a Stock Option Plan (the "1993 Plan"). Under
the 1993 Plan, as amended, options to purchase up to an aggregate of 975,000
shares of Common Stock were reserved for grants to key employees of the Company.
The 1993 Plan limits the maximum number of shares that may be granted to any
person eligible under the 1993 Plan to 325,000. All options have been issued
with exercise prices equal to the fair market value at date of grant. All
options granted under the 1993 Plan become fully vested and exercisable on the
second anniversary of the date of grant. Each option granted under the 1993 Plan
will terminate no later than ten years after the date the option was granted.

Metrocall 1996 Stock Option Plan in May 1996, discussed below, no additional
options will be granted under the 1993 Plan.
 
     In 1993, the Company also adopted a Directors Stock Option Plan (the
"Directors Plan"). Under the Directors Plan, options to purchase up to an
aggregate of 25,000 shares of Common Stock are available for grants to directors
of the Company who are neither officers nor employees of the Company ("Eligible
Director"). Options issued under the Directors Plan vest fully on the six-month
anniversary of the date of grant. Each Eligible Director was also granted an
option to purchase 1,000 shares of Common Stock on the first and second
anniversaries of the grant date of the initial option if the director continues
to be an Eligible Director on each of such anniversary dates.
 
     In May 1996, the Company's stockholders approved the Metrocall 1996 Stock
Option Plan (as amended, the "1996 Plan") an amendment to which was approved by
the stockholders in November 1996. Under the 1996 Plan, options to purchase up
to an aggregate of 2,000,000 shares of Common Stock were reserved for grant to
key employees, officers and nonemployee directors who have never been employed
by the Company ("Qualified Director"). The 1996 Plan limits the maximum number
of shares that may be granted to any person eligible under the 1996 Plan to
750,000. If any option granted under the 1996 Plan expires or terminates prior
to exercise in full, the shares subject to that option shall be available for
future grants under the 1996 Plan. All employees of the Company and Qualified
Directors of the Company are eligible to participate in the 1996 Plan. Each
option granted under the 1996 Plan will terminate no later than ten years after
the date the option was granted.
 
     Under the 1996 Plan, both incentive stock options and nonstatutory stock
options are available for employees. For incentive stock options, the option
price shall not be less than the fair market value of a share of Metrocall
Common Stock on the date the option is granted. For nonstatutory options, the
option price shall not be less than the par value of Metrocall Common Stock. All
options granted to Qualified Directors shall be nonstatutory options. Upon
approval of the 1996 Plan, each Qualified Director was granted an initial option
to purchase 10,000 shares of Metrocall Common Stock. Thereafter, every Qualified
Director will be granted an initial option to purchase 10,000 shares of
Metrocall Common Stock at the time the Qualified Director commences service on
the board of directors. Subsequently, each Qualified Director who received an
initial grant of an option shall receive an additional option to purchase 1,000
shares of Metrocall Common Stock on each anniversary of the initial option,
provided that the director continues to be a Qualified Director on each
anniversary date. Options granted to Qualified Directors shall become fully
vested six months after the date of grant. The exercise price for options
granted to Qualified Directors shall be the fair market value of Metrocall
Common Stock on the date the option is granted or the date of shareholder
approval of the 1996 Plan, if later.
 
     In connection with the merger of Metrocall and FirstPAGE, Metrocall
exchanged options to purchase 47,387 shares of Metrocall Common Stock with
former FirstPAGE option holders. These options are fully vested and exercisable
and have an exercise price of approximately $1.04 per common share. Of the total
options exchanged, 23,219 were unexercised at December 31, 1996.
 
     In connection with the merger of Metrocall and A+ Network, Metrocall
exchanged options to purchase shares of Metrocall Common Stock with former A+
Network option holders. These options are fully vested and exercisable and have
an exercise price of approximately $6.04 per common share. Of the total options
exchanged, none had been exercised through December 31, 1996.

     On September 18, 1996 the Compensation Committee of the Board of Directors
approved a change in the exercise price for substantially all outstanding Common
Stock options for current employees and officers. The new exercise price was
$7.94 per share, the fair market value on the date of the change. On February 5,
1997, the Compensation Committee of the Board of Directors approved a change in
the exercise price for substantially all outstanding options for current
employees, officers and directors. The new exercise price was $6.00 per share,
the fair market value on the date of the change. Repricing of options for
nonemployee directors is subject to stockholder approval.
 
  Employee Stock Purchase Plan
 
     In May 1996, the Company's stockholders approved the Metrocall, Inc.
Employee Stock Purchase Plan (the "Stock Purchase Plan"). Substantially all
full-time employees are eligible to participate in the Stock Purchase Plan.
Participants in the Stock Purchase Plan may elect to purchase shares of
Metrocall Common Stock at the lesser of 85% of the fair market value on either
the first or last trading day of each payroll deduction period. No employee may
purchase in one calendar year shares of Common Stock having an aggregate fair
market value in excess of $25,000. Total shares authorized for issuance under
the Stock Purchase Plan are 300,000. In July 1996, 11,942 shares were issued
under the Stock Purchase Plan for $9.24 per share. At December 31, 1996, 35,203
shares were due to participants in the Stock Purchase Plan at a price of $4.14
per share. The weighted-average fair value of shares sold in 1996 was $6.56 per

compensation cost has been recognized for its stock option and stock purchase
plans other than for approximately $285,000 of compensation expense recognized
in 1995 upon amending option agreements with certain former employees (see Note
5). Had compensation cost for the Company's stock-based compensation plans been
determined for 1995 and 1996 grants using the fair value at the grant dates for
awards under those plans consistent with the method of SFAS Statement No. 123,
the Company's loss and loss per share information would have been increased to

     Because the Statement No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.
 
     The weighted-average fair value of options granted in 1995 and 1996 was
$7.34 and $5.89, respectively, after the effect of repricing discussed above.
The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions used for grants in 1995 and 1996: risk free rate of 6.43%, expected
lives of ten years and expected volatility of 60.6%.
 
9.  COMMITMENTS AND CONTINGENCIES
 
  Legal and Regulatory Matters
 
     The Company is subject to certain legal and regulatory matters in the
normal course of business. In the opinion of management, the outcome of such
assertions will not have a material adverse effect on the financial position or
the results of the operations of the Company.
 
     In April 1996, the Company entered into an agreement to purchase certain of
the assets of Source One Wireless, Inc. ("Source One") and placed $1 million
cash in escrow. On June 26, 1996, the Company advised Source One that Source One
had failed to meet certain conditions to completion of the transaction and
terminated the agreement. On September 20, 1996, Source One filed an action in
the Circuit Court of Cook County, Illinois, claiming that the Company had
breached the agreement and seeking specific performance of the purchase
agreement or unspecified damages in excess of $80 million. The Company intends
to vigorously defend the claims in this action and believes it has meritorious
defenses to this action.
 
     The Company has received communications from a seller in connection with an
acquisition that occurred in 1994 asserting damages resulting from alleged
misrepresentations in connection with the acquisition. The seller, who received
shares of the Company's Common Stock as acquisition consideration, is seeking to
receive additional shares of Common Stock and participation on the Company's
board of directors, among other requests. To date, no claim has been filed;
however, if necessary, management will vigorously defend any legal actions that
might arise from such assertions.

  Leases
 
     The Company has various leasing arrangements (as lessee) for office space
and communications equipment sites. Rental expense related to operating leases
was approximately $2,627,000, $4,818,000, and $8,612,000 for the years ended
December 31, 1994, 1995 and 1996, respectively.
 
     Minimum rental payments as of December 31, 1996, required under operating
leases that have initial or remaining noncancelable lease terms in excess of one
year are as follows (in thousands):

</TABLE>
 
     Rent expense for lease agreements between the Company and related parties
for office space, tower sites and transmission systems, excluding consolidated
entities, was approximately $215,000, $359,000 and $334,000 for the years ended
December 31, 1994, 1995 and 1996, respectively.
 
     The Company leases office and warehouse space from a company owned by a
director of the Company. The annual rental commitment under these leases, which
expire in 1998, is approximately $520,000. The Company believes the terms of
these leases are at least as favorable as those that could be obtained from a
non-affiliated party.
 
  Profit Sharing Plan and Retirement Benefits
 
     In 1995, the Company adopted the Metrocall, Inc. Savings and Retirement
Plan (the "Plan") a combination employee savings plan and discretionary
profit-sharing plan that covers substantially all full-time employees. The Plan
qualifies under section 401(k) of the Internal Revenue Code (the "IRC"). Under
the Plan, participating employees may elect to voluntarily contribute on a
pretax basis between 1% and 15% of their salary up to the annual maximum
established by the IRC. The Company has agreed to match 25% of the employee's
contribution, up to 3% of each participant's gross salary. Contributions made by
the Company vest 20% per year beginning on the second anniversary of the
participant's employment. Profit sharing contributions are discretionary. The
Company's expense for contributions under this Plan and the Company's previous
profit sharing plan, recorded in the accompanying consolidated statements of
operations were $200,000, $93,000, and $112,000 for the years ended December 31,
1994, 1995 and 1996, respectively.
 
10.  EQUITY INVESTMENT
 
     The Company acquired a 33 1/3% interest in Solo America, a national sales
and marketing distribution company. In its relationship with Solo America, the
Company has agreed to advance $1 million to Solo America, payable in three
installments, in exchange for Solo America's efforts to market the Company's
paging products and services. Through December 31, 1996, the Company has made
equity installments totaling $666,666. The Company recorded a charge of
approximately $207,000 to recognize the Company's share of Solo America's net
loss in the year ended December 31, 1996. The Company has recorded a further
reserve against the investment in Solo America at December 31, 1996 of
approximately $238,000.

11.  INCOME TAXES
 
     As of December 31, 1996, the Company had net operating loss and investment
tax credit carryforwards of approximately $122.8 million and $1.1 million,
respectively, which expire in the years 1999 through 2011. The benefits of these
carryforwards may be limited in the future due to significant changes in the
ownership of the Company. Net operating loss carryforwards may be used to offset
up to 90 percent of the Company's alternative minimum taxable income. The
provision for alternative minimum tax will be allowed as a credit carryover
against regular tax in the future in the event regular tax exceeds alternative
minimum tax expense. To the extent that acquired net operating losses are
utilized in future periods, the benefit will first be recognized to reduce
acquired intangible assets before reducing the provision for income taxes.
 
     Under the provisions of SFAS No. 109, the tax effect of the net operating
loss and investment tax credit carryforwards, together with net temporary
differences, represents a net deferred tax asset for which management has
reserved 100% due to the uncertainty of future taxable income. These
carryforwards will be benefited for financial reporting purposes when utilized
to offset future taxable income.
 
     The components of net deferred tax assets (liabilities) were as follows as
of December 31, 1995 and 1996 (in thousands):

     The sum of the per share amounts may not equal the annual amounts because
of the changes in the weighted-average number of shares outstanding during the
year. The loss from operations in the quarter ended December 31, 1995, includes
a charge of $2,050,000 for management reorganization charge described in Note 5.
Net loss for the three months ended December 31, 1995 and 1996, includes charges
for extraordinary items, net of applicable tax benefit, if any, for the
write-off of deferred financing costs of $2,695,000 ($0.23 per share) and costs
associated with the repurchase of the A+ Notes of $3,675,000 ($0.23 per share),
respectively, discussed in Note 6.
    
 
14.  PENDING ACQUISITION
 
     On April 22, 1996, the Company signed a definitive acquisition agreement
(the "Page America Agreement") with Page America Group, Inc. of Hackensack, New
Jersey ("Page America"). The Page America Agreement was subsequently amended on
January 30, 1997 (the "Amended Page America Agreement"). Pursuant to the Amended
Page America Agreement, as subsequently modified, (i) Metrocall will acquire
substantially all of the assets and assume substantially all of Page America's
accounts payable and certain obligations under various office and equipment
leases and (ii) Page America will receive (a) $25 million in cash subject to
reduction for amounts payable for pagers provided by the Company, (b)1,500
shares of Series B Preferred Stock with a stated value of $15 million, (c)
762,960 shares of the Company's Common Stock and (d) additional shares of the
Company's Common Stock or other equity securities (CSE Preferred Stock, see Note
8) having a value equal to $15 million, subject to adjustment based on certain
changes in Page America's working capital and service revenues. Consummation of
the Page America acquisition is subject to a number of conditions including, but
not limited to, receipt of all necessary regulatory approvals and approval by
the Page America stockholders. There can be no assurance that such approvals
will be obtained. The pending transaction, if consummated, will be accounted for
as a purchase.
