ITEM 1.     BUSINESS

General

    Arch Communications Group, Inc. ("Arch" or the "Company") is a leading
provider of wireless messaging services, primarily paging services, and had 3.3
million pagers in service as of December 31, 1996. Arch has operations in a
total of 41 states and 180 of the 200 largest markets in the United States.

    The Company provides local, regional and nationwide paging services
employing digital networks covering approximately 85% of the United States
population. Arch offers four types of paging services: digital display,
alphanumeric display, tone-only and tone-plus-voice. Arch also offers enhanced
or complementary services, including voice mail, personalized greetings, message
storage and retrieval, pager loss protection and pager maintenance. As part of
its business, the Company rents, sells and repairs pagers. The Company is
licensed by the Federal Communications Commission ("FCC") to provide paging and
related services in the markets it serves. Generally, such licenses are
exclusive to a particular radio frequency, although multiple frequencies may be
licensed in any given market. See "Business -- Regulation".

    Arch has grown rapidly through a combination of internal growth and
acquisitions since it began operations in 1986. The Company's net revenues (the
sum of service revenues and product sales, less the cost of product sales), the
normal presentation of revenues in the paging industry, were $303,901,000 in the
year ended December 31, 1996. The Company's operating cash flow, or earnings
before interest, taxes, depreciation and amortization ("EBITDA"), the most
relevant measure of operating performance for the paging industry, was
$105,801,000 for the year. Because paging is a capital intensive industry,
particularly during periods of rapid growth, and because the Company has made
sizeable acquisitions accounted for by the purchase method of accounting, very
significant depreciation and amortization expenses are charged against Arch's
operations. Because the Company has incurred large amounts of debt in its growth
and in the course of its acquisition program, significant interest expense is
charged against its operations. As a result of these charges, the Company
historically has incurred net losses, including a net loss of $114,662,000 for
the year ended December 31, 1996.

ACQUISITION OF USA MOBILE

     On September 7, 1995, Arch Communications Group, Inc., a Delaware
corporation ("Old Arch"), completed its acquisition of USA Mobile, a Delaware
corporation, through the merger (the "Merger") of Old Arch with and into USA
Mobile, which simultaneously changed its name to Arch Communications Group, Inc.
In accordance with generally accepted accounting principles, Old Arch was
treated as the acquirer in the Merger for accounting and financial reporting
purposes, and the Company reports the historical financial statements of Old
Arch as the historical financial statements of the Company. As used herein,
unless the context otherwise requires, the terms "Arch" or the "Company" refer
to Arch Communications Group, Inc. from and after the Merger and Old Arch prior
to the Merger, in each case together with its wholly-owned direct and indirect
subsidiaries, and the term "USA Mobile" refers to USA Mobile Communications
Holdings, Inc. prior to the Merger together with its wholly-owned direct and
indirect subsidiaries.

PAGING INDUSTRY OVERVIEW

    Paging is a method of wireless communication which uses an assigned radio
frequency to contact a paging subscriber anywhere within a designated service
area. A subscriber carries a pager which 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 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 broadcast a signal
that is received by the pager a 


                                       3
<PAGE>   4
subscriber carries, which alerts the subscriber by a tone or vibration that
there is a voice, tone, digital or alphanumeric message.

    Arch believes that paging is the most cost-effective form of mobile wireless
communications. Paging has an advantage over conventional telephone service
because a pager's reception is not restricted to a single location, and over a
cellular telephone because a pager is smaller, has a longer battery life and,
most importantly, because pagers and air time required to transmit an average
message cost less than equipment and air time for cellular telephones. Paging
subscribers generally pay a flat monthly service fee for pager services,
regardless of the number of messages, unlike cellular telephone subscribers,
whose bills typically have a significant variable usage component. For these
reasons, some cellular subscribers use a pager in conjunction with their
cellular telephone to screen incoming calls and thus lower the expense of
cellular telephone service.

    Industry sources estimate that, since 1990, the number of pagers in service
in the United States has grown at an annual rate of nearly 30% and will continue
to grow at an annual rate of approximately 15% until the year 2000. Based on
industry sources, Arch believes that there were approximately 42 million pagers
in service in the United States at December 31, 1996. Factors contributing to
this growth include: (i) a continuing shift towards a service-based economy;
(ii) increasing mobility of workers and the population at large; (iii)
increasing awareness of the benefits of mobile communications among the
population at large; (iv) the relatively high cost of two-way mobile
communications, such as cellular telephone services; (v) introduction of new or
enhanced paging services, including nationwide paging capability; (vi)
continuing improvements in the performance of paging equipment; and (vii)
significant price/performance improvements in paging services. The paging
industry has undergone substantial consolidation over the past ten years, and
Arch believes that the top five paging carriers represent approximately 50% of
the pagers in service. Nonetheless, Arch believes that the paging industry
remains fragmented, with more than 300 licensed carriers in the United States,
and will continue to undergo consolidation.

    The paging industry has benefited from technological advances resulting from
research and development conducted by vendors of pagers and transmission
equipment. Such advances include microcircuitry, liquid crystal display
technology and standard digital encoding formats, which have enhanced the
capability and capacity of paging services while lowering equipment and air time
costs. Technological improvements have enabled Arch to provide better quality
services at lower prices to its subscribers and have generally contributed to
strong growth in the market for paging services.

    The paging industry has traditionally distributed its services through
direct marketing and sales activities. In recent years, additional channels of
distribution have evolved, including: (i) carrier-operated stores; (ii)
resellers, who purchase paging services on a wholesale basis from carriers and
resell those services on a retail basis to their own customers; (iii) agents who
solicit customers for carriers and are compensated on a commission basis; and
(iv) retail outlets that often sell a variety of merchandise, including pagers
and other telecommunications equipment. While most paging subscribers
traditionally have been business users, industry observers believe that pager
use among consumers has increased significantly in recent years. In addition,
paging subscribers have increasingly chosen to purchase rather than lease their
pagers. These trends are expected to continue.

BUSINESS STRATEGY

    Arch's strategic objective is to strengthen its position as one of the
leading paging companies in the United States. Arch believes that larger,
multi-market paging companies enjoy a number of competitive advantages,
including: (i) operating efficiencies resulting from more intensive utilization
of existing paging systems; (ii) economies of scale in purchasing and
administration; (iii) broader geographic coverage of paging systems; (iv)
greater access to capital markets and lower costs of capital; (v) the ability to
obtain additional radio spectrum; (vi) the ability to offer high-quality
services at competitive prices; and (vii) enhanced ability to attract and retain
management personnel. Arch believes that the current size and scope of its
operations afford it many of these advantages. Arch also believes that major
paging companies need to have national scope and presence in order to attract
marketing affiliations and other opportunities for growth, and Arch believes
that its ongoing expansion program will effectively complete Arch's national
scope and presence and position Arch to exploit such opportunities while
continuing to pursue its growth strategy.




                                       4
<PAGE>   5
    Arch employs a three-part growth strategy to expand its subscriber base and
geographic operations:

    Continued Market Development and Penetration. Arch increases its subscriber
base through continued development and penetration of its existing markets,
primarily through sales and marketing efforts. Expansion of Arch's sales and
marketing activities within areas of existing service coverage broadens Arch's
potential subscriber base with minimal incremental capital investment and, over
time, contributes to higher margins through increased system utilization.

    Expansion of Sales and Marketing Activities. Arch expands its marketing
coverage, principally by opening new sales offices, to areas contiguous to
existing sales operations within Arch's current system coverage. Expansion of
sales and marketing activities into new markets contiguous to existing sales
operations may solidify Arch's presence in existing markets and enable Arch to
leverage further its infrastructure within these markets.

    Acquisitions. Arch makes two types of acquisitions; fold-in and strategic.
Fold-in acquisitions are acquisitions of paging businesses located within or
adjacent to Arch's current system coverage. Fold-in acquisitions increase Arch's
subscriber base and revenues and offer opportunities to achieve operating
efficiencies by consolidating staff, eliminating duplicative overhead and
integrating the acquired subscribers into Arch's own paging system and billing
and collection processes. Arch also makes strategic acquisitions to expand
Arch's geographic coverage into new markets outside of Arch's current system
coverage.

    Although today Arch operates in 90 of the top 100 U.S. markets, the Company
historically has focused on medium-sized and small market areas with lower rates
of pager penetration and attractive demographics and Arch believes that such
markets will continue to offer significant opportunities for growth. In
addition, Arch believes that its increasing national scope and presence will
provide Arch with growth opportunities in larger markets, including major
metropolitan areas adjacent to certain of Arch's existing markets.

    Arch believes that its selection of low-cost operator status as its
competitive tactic provides it with flexibility to offer competitive prices
while still achieving target margins and EBITDA. Arch maintains a low-cost
operating structure through a combination of (i) the consolidation of certain
operating functions, including centralized purchases from key vendors, to
achieve economies of scale, and (ii) the installation of efficient, high-quality
transmission systems.

    Arch believes that its decentralized organizational structure enables it to
offer superior customer service and to respond to subscriber needs quickly and
effectively. Arch's operating regions operate largely as independent entities,
while strategic planning, equipment purchasing, capital formation, legal,
acquisition and similar functions are conducted on a centralized basis. The
management of each operating region makes staffing, administrative, operational
and marketing decisions within guidelines established by the senior management
of Arch.

    Arch has taken steps to position itself to participate in new and emerging
services and applications in narrowband wireless personal communications
("N-PCS"). These initiatives include (i) nationwide paging services, (ii) an
equity investment in CONXUS Communications, Inc. (formerly PCS Development
Corporation), which holds exclusive rights to regional two way messaging
licenses which provide nationwide coverage, and (iii) Arch's equity investment
in Benbow PCS Ventures, Inc. ("Benbow"), which gives Arch access to two regional
narrowband PCS licenses controlled by Benbow which will provide coverage to a
substantial portion of the western United States.

PAGING OPERATIONS

    Arch provides paging service to subscribers for a monthly fee. Subscribers
either lease the pager from Arch for an additional fixed monthly fee or they own
the pager, having purchased it either from Arch or from another vendor. The
monthly service fee is generally based upon the type of service provided, the
geographic area covered, the number of pagers provided to the customer and the
period of the subscriber's commitment. Subscriber-owned pagers provide a more
rapid recovery of Arch's capital investment than pagers owned and maintained by
Arch, but may generate less recurring revenue. Arch also sells pagers to
third-party resellers who lease or resell pagers to their own subscribers and
resell Arch's paging services under marketing agreements.




                                       5
<PAGE>   6
    Arch also provides enhancements and ancillary services such as voice mail,
personalized greetings, message storage and retrieval, pager loss protection and
pager maintenance services. Voice mail allows a caller to leave a recorded
message that is stored in Arch's computerized message retrieval center. When a
message is left, the subscriber can be automatically alerted through the
subscriber's pager and can retrieve the stored message by calling Arch's paging
terminal. Personalized greetings allow the subscriber to record a message to
greet callers who reach the subscriber's pager or voice mail box. Message
storage and retrieval allows a subscriber who leaves Arch's service area to
retrieve calls that arrived during the subscriber's absence from the service
area. Pager loss protection allows subscribers who lease pagers to limit their
costs of replacement upon loss or destruction of the pager. Pager maintenance
services are offered to subscribers who own their own equipment.

SUBSCRIBERS AND MARKETING

    Arch's paging accounts are generally businesses with employees who travel
frequently but must be immediately accessible to their offices or customers.
Arch's subscribers include proprietors of small businesses, professionals,
management and medical personnel, field sales personnel and service forces,
members of the construction industry and trades, and real estate brokers and
developers. In addition, Arch believes that pager use among consumers will
increase significantly in the future, although consumers do not currently
account for a substantial portion of Arch's subscriber base.

    Arch markets its paging services through a direct marketing and sales
organization which, as of December 31, 1996, operated approximately 200 retail
stores. Arch also markets its paging services indirectly through independent
resellers, agents and retailers. Arch typically offers resellers paging
services in large quantities at wholesale rates that are lower than retail
rates, and resellers offer the services to end-users at a mark-up. Arch's costs
of administering and billing resellers are lower than the costs of direct
end-users on a per pager basis. Arch also acts as a reseller of other paging
carriers' services when existing or potential Arch customers have travel
patterns that require paging service beyond the coverage of Arch's own
networks.

COMPETITION

    Arch experiences competition from one or more competitors in all markets in
which it operates, but no single competitor competes with Arch in all of its
markets, although certain competitors hold nationwide licenses that would enable
them to compete in all of Arch's markets if they choose to do so. Although some
of Arch's competitors are small, privately owned companies serving one market
area, others are large diversified telecommunications companies, including AT&T.
Some of Arch's competitors possess financial, technical and other resources
greater than those of Arch. Major paging carriers that currently compete in one
or more of Arch's markets include Paging Network, Inc., MobileMedia Corporation
and AirTouch Communications, Inc. As paging services become increasingly
interactive, and as two-way services become increasingly competitive, the scope
of competition for communications service customers in Arch's markets may
broaden. For example, the FCC has commenced issuing licenses for the provision
of broadband personal communications services, with most grants going to major
telecommunications companies or conglomerates with greater financial resources
than Arch. Sprint, through its venture with American Personal Communications,
has initiated broadband PCS services in the Washington, D.C. and Baltimore
markets which include "short messaging", a form of advanced alphanumeric paging,
as part of its two-way voice communications product. In addition, the FCC has
created potential sources of competition by opening up new spectrum for such
services as General Wireless Communications Services ("GWCS") and Wireless
Communications Services ("WCS") as well as speeding up licensing of other
services through auctions including the Local Multipoint Distribution Service
("LMDS"), 220-222 MHz and broadband PCS services.

    Arch believes that competition for paging subscribers is based on quality of
service, geographic coverage and price. Arch believes it generally competes
effectively based on these factors.

SOURCES OF EQUIPMENT

    Arch does not manufacture any of the pagers or other equipment used in its
paging operations. The equipment used in Arch's paging operations is generally
available for purchase from multiple sources. Arch centralizes price and
quantity negotiations for all of its operating subsidiaries in order to achieve
cost savings from volume purchases. Arch buys pagers 


                                       6
<PAGE>   7
primarily from Motorola and NEC and purchases terminals and transmitters
primarily from Glenayre and Motorola. Arch anticipates that equipment and pagers
will continue to be available in the foreseeable future, consistent with normal
manufacturing and delivery lead times.

    Because of the high degree of compatibility among different models of
transmitters, computers and other paging equipment manufactured by suppliers,
Arch is able to design its systems without being dependent upon any single
source of such equipment. Arch routinely 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. Arch believes that its
paging system equipment is among the most technologically sophisticated in the
paging industry.

    REGULATION

    Paging operations and the construction, modification, ownership and
acquisition of paging systems are subject to extensive regulation by the FCC
under the Communications Act of 1934, as amended (the "Communications Act"),
and, to a much more limited extent, by public utility or public service
commissions in certain states. The following description does not purport to be
a complete discussion of all present and proposed legislation and regulations
relating to Arch's paging operations.

    FEDERAL REGULATION

    Paging companies historically have been subject to different federal
regulatory requirements depending upon whether they were providing service as a
Radio Common Carrier ("RCC"), a Private Carrier Paging ("PCP") operator or as a
reseller. Arch's paging operations encompass RCC, PCP and resale operations.
However, federal legislation enacted in 1993 required the FCC to reduce the
disparities in the regulatory treatment of similar mobile services (such as RCC
and PCP services), and the FCC has taken, and continues to take, actions to
implement this legislation.

    Under the new regulatory structure, all of Arch's paging services are
classified as commercial mobile radio service ("CMRS"). As a CMRS provider, Arch
is regulated as a common carrier, except that the FCC has exempted paging
services, which have been found to be highly competitive, from some typical
common carrier regulations, such as tariff filing requirements.

    The classification of Arch's paging operations as CMRS affects the level of
permissible foreign ownership, the nature and extent of state regulation and the
regulatory fees to which Arch is subject. In addition, the FCC now is required
to resolve competing requests for CMRS spectrum by conducting an auction, which
may have the effect of increasing the costs of acquiring additional spectrum in
markets in which Arch operates. Also, Arch is obligated to pay certain
regulatory fees in connection with its paging operations.

    The FCC's review and revision of rules affecting paging companies is ongoing
and the regulatory requirements to which Arch is subject may change
significantly over time. For example, the FCC has adopted a market area
licensing scheme for all paging channels under which carriers would be licensed
to operate on a particular channel throughout a broad geographic area (for
example, a Major Trading Area as defined by Rand McNally) rather than being
licensed on a site-by-site basis. These geographic area licenses will be awarded
pursuant to auction rules and procedures for which the FCC has issued initial
rules and asked for comments on some further proposals. Under the newly adopted
rules, existing paging facilities would be entitled to protection as
grandfathered systems. Arch is participating actively in this proceeding in
order to protect its existing operations and retain flexibility, on an interim
and long-term basis, to modify systems as necessary to meet subscriber demands.
The FCC is also considering whether CMRS operators should be obligated to
interconnect their systems with others and be prohibited from placing
restrictions on the resale of their services (except with respect to paging,
which has already been relieved of the obligation to provide resale). Arch
depends in its business on the assignment and use of standard and toll free
telephone numbers for its paging units. The FCC has proceedings underway that
may have a significant impact on the manner in which telephone numbers are
assigned and utilized by common carriers, including paging companies, and on the
ability of subscribers to retain their telephone numbers if, or when, they
change paging companies. Some of the alternatives under consideration by the
FCC, if adopted, could increase the cost to Arch of telephone numbers, restrict
the manner in which certain numbers could be used or affect the ability of Arch
to retain certain numbers previously assigned.



                                       7

    The Communications Act requires that Arch obtain licenses from the FCC to
use radio frequencies to conduct its paging operations within specified
geographic areas, and Arch is licensed by the FCC to provide paging services in
each geographic area in which it has operations. Licenses issued by the FCC to
Arch set forth the technical parameters, such as power strength and tower
height, under which Arch is authorized to use those frequencies. In many
instances, Arch requires the prior approval of the FCC before it can implement
any significant changes to its radio systems. Upon the effective date of FCC's
market area licensing rules, all of these site-specific licensing obligations
will be eliminated, with the exception of applications still required by Section
22.369 of the FCC Rules (request for authority to operate in a designated Quiet
Zone), Section 90.77 (request for authority to operate in a protected radio
receiving location) and Section 1.1301 et seq. (construction/modification that
may have a significant environmental impact), or for coordination with Canada or
Mexico.

    The FCC licenses granted to Arch are for varying terms of up to ten years,
at the end of which time renewal applications must be approved by the FCC. Some
of the authorizations held by Arch are subject to FCC construction obligations
which must be met for the licenses to be retained. In the past, FCC renewal
applications routinely have been granted in most cases upon a demonstration of
compliance with FCC regulations and adequate service to the public. The FCC has
granted each renewal application Arch has filed. Although Arch is unaware of any
circumstances which would prevent the grant of any pending or future renewal
applications, no assurance can be given that any of Arch's renewal applications
will be free of competing applications or will be granted by the FCC.
Furthermore, although revocation and involuntary modification of licenses are
extraordinary regulatory measures, the FCC has the authority to restrict the
operation of licensed facilities or to revoke or modify licenses.

    The Communications Act requires licensees, such as Arch, to obtain prior
approval from the FCC for the assignment or transfer of control of any
construction permit or station license, or any rights thereunder. The
Communications Act also requires prior approval by the FCC for acquisitions of
the licenses of, or controlling equity interests in, other paging companies by
Arch. To date, the FCC has approved each assignment and transfer of control for
which Arch has sought approval. Although there can be no assurance that any
requests for approval or applications filed by Arch will be acted upon in a
timely manner by the FCC, or that the FCC will grant the approval or relief
requested, Arch knows of no reason to believe any such requests, applications or
relief will not be approved or granted. Currently underway at the FCC is a
proceeding wherein the FCC's Wireless Telecommunications Bureau (the Bureau
directly regulating Arch's paging activities) is proposing to eliminate all
filing requirements associated with pro forma assignments and transfers of
control of wireless authorizations. This proposal would expedite the process and
reduce the cost related to corporate reorganizations.

    The Communications Act also limits foreign ownership of entities that hold
licenses from the FCC. Because Arch, through its subsidiaries, holds licenses
from the FCC, in general, no more than 25% of Arch's stock may be owned or voted
by aliens or their representatives, a foreign government or its representatives,
or a foreign corporation.

    The recently enacted Telecommunications Act of 1996 directly affects Arch.
Some aspects of the new statute could have a beneficial effect on Arch's
business. For example, proposed federal guidelines regarding antenna siting
issues may remove local and state barriers to the construction of communications
facilities, and efforts to increase competition in the local exchange and
interexchange industries may reduce the cost to Arch of acquiring necessary
communications services and facilities. On the other hand, some provisions
relating to telephone number portability, the assignment of new area codes, and
universal service obligations may place additional burdens upon Arch or subject
Arch to increased competition.

    STATE REGULATION

    In addition to regulation by the FCC, certain states impose various
regulations on the common carrier paging operations of Arch. Regulation in some
states historically required Arch to obtain certificates of public convenience
and necessity before constructing, modifying or expanding paging facilities or
offering or abandoning paging services. Rates, terms and conditions under which
Arch provided services, or any changes to those rates, have also been subject to
state regulation. However, under the Federal Budget Reconciliation Act of 1993
(the "Budget Act"), as a general rule, states are preempted from exercising rate
and entry regulation of CMRS, but may choose to regulate other terms and
conditions of service (for example, requiring the identification of an agent to
receive complaints). In certain instances, the construction and operation 



                                       8
<PAGE>   9
of radio transmitters also will be subject to zoning, land use, public health
and safety, consumer protection and other state and local taxes, levies and
ordinances. States also were accorded an opportunity to petition the FCC for
authority to continue to regulate CMRS rates, which petitions are to be
evaluated by the FCC applying the statutory criteria set forth in the Budget
Act.

    Seven states in which Arch operates applied to retain some jurisdiction over
CMRS, although certain of these requests were limited to two-way services and
not paging services. The FCC denied these states' requests, and those rulings
have become final, although there is nothing to prevent these states from filing
new petitions with the FCC for authority to regulate CMRS rates. States also may
regulate terms and conditions (other than entry or rates) of paging services
provided within such states. Arch believes that to date all required state
filings for Arch's paging operations have been made.

    FUTURE REGULATION

    From time to time, legislation which could potentially affect Arch, either
beneficially or adversely, is proposed by federal or state legislators. There
can be no assurance that legislation will not be enacted by the federal or state
governments, or that regulations will not be adopted or actions taken by the FCC
or state regulatory authorities, which might materially adversely affect the
business of Arch. Changes such as the allocation by the FCC of radio spectrum
for services that compete with Arch's business could adversely affect Arch's
results of operations.

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

OVERVIEW

    Arch is a leading provider of wireless messaging services, primarily paging
services, and had 3.3 million pagers in service as of December 31, 1996. From
September 1, 1993 through December 31, 1996, the Company's total subscriber base
grew at a compound annual rate of 115.7% and its compound annual rate of
internal subscriber base growth (excluding pagers added through acquisitions)
was 74.9%.

    Arch derives the majority of its revenues from fixed periodic (usually
monthly) fees, not dependent on usage, charged to subscribers for paging
services. As long as a subscriber remains on service, operating results benefit
from the recurring payments of the fixed periodic fees without incurrence of
additional selling expenses by Arch. Arch's service, rental and maintenance
revenues and the related expenses exhibit substantially similar growth trends.
Arch's average paging revenue per subscriber has declined over the past three
years for two principal reasons: (i) the percentage of subscriber-owned and
reseller-owned pagers for which Arch receives no recurring equipment rental
revenue has increased from 36% of pagers in service at August 31, 1993 to 53% of
pagers in service at December 31, 1996 and (ii) the percentage of net new pagers
in service added to Arch's subscriber base through indirect channels has
increased from 24% in the year ended August 31, 1993 to 39% in the year ended
December 31, 1996. Most of the indirect channel additions are derived from
resellers who purchase air time from Arch at wholesale prices. The reduction in
average paging revenue per subscriber resulting from these trends has been more
than offset by the elimination of associated expenses so that Arch's margins
have improved over such period.

    Arch's total revenues have increased from $75.9 million in the year
ended December 31, 1994 to $162.6 million in the year ended December 31, 1995
and to $331.4 million in the year ended December 31, 1996. Over the same
periods, through operating efficiencies and economies of scale, Arch has been
able to reduce its per pager operating costs to enhance its competitive
position in its markets. Due to the rapid growth in its subscriber base, Arch
has incurred significant selling expenses, which are charged to operations in
the year incurred. Arch has reported net losses of $6.5 million, $36.6 million
and $114.7 million in the years ended December 31, 1994, 1995 and 1996,
respectively, as a result of significant depreciation and amortization expenses
related to acquired and developed assets and interest charges associated with
indebtedness. However, as its subscriber base has grown, Arch's operating
results have improved, as evidenced by an increase in its earnings before
interest, taxes, depreciation and amortization ("EBITDA") from $18.0 million in
the year ended December 31, 1994 to $47.2 million in the year ended December
31, 1995 and to $105.8 million in the year ended December 31, 1996.

    EBITDA is a standard measure of financial performance in the paging industry
and also is one of the financial measures used to calculate whether Arch and its
subsidiaries are in compliance with the covenants under their respective debt
agreements, but should not be construed as an alternative to operating income or
cash flows from operating activities as determined in accordance with generally
accepted accounting principles. Arch's financial objective is to increase its
EBITDA, as such earnings are a significant source of funds for servicing
indebtedness and for investment in continued growth, including purchase of
pagers and paging system equipment, construction and expansion of paging
systems, and possible acquisitions.

    On October 17, 1994, Arch announced that it was changing its fiscal year end
from August 31 to December 31. Arch filed a transition report on Form 10-K with
audited financial statements for the period September 1, 1994 through December
31, 1994 and has elected to include herein, for comparative purposes, unaudited
financial statements for the periods September 1, 1993 through December 31, 1993
and January 1, 1994 through December 31, 1994. Arch's quarterly and annual
reporting is now based on its fiscal year end of December 31.

<PAGE>   15
    YEAR ENDED DECEMBER 31, 1996 COMPARED WITH YEAR ENDED DECEMBER 31, 1995

    Total revenues increased $168.8 million, or 103.8%, to $331.4 million in the
year ended December 31, 1996 from $162.6 million in the year ended December 31,
1995 and net revenues increased $162.1 million, or 114.3%, from $141.8 million
to $303.9 million over the same period. Service, rental and maintenance
revenues, which consist primarily of recurring revenues associated with the sale
or lease of pagers, increased $152.9 million, or 110.4%, to $291.4 million in
the year ended December 31, 1996 from $138.5 million in the year ended December
31, 1995. These increases in revenues were due primarily to the increase in the
number of pagers in service from 2,006,000 at December 31, 1995 to 3,295,000 at
December 31, 1996. Acquisitions of paging companies added 474,000 pagers in
service during 1996, with the remaining 815,000 pagers added through internal
growth. Maintenance revenues represented less than 10% of total service, rental
and maintenance revenues in the years ended December 31, 1995 and 1996. Arch
does not differentiate between service and rental revenues. Product sales, less
cost of products sold, increased 274.0% to $12.5 million in the year ended
December 31, 1996 from $3.3 million in the year ended December 31, 1995 as a
result of a greater number of pager unit sales.

    Service, rental and maintenance expenses, which consist primarily of
telephone line and site rental expenses, increased to $65.0 million (21.4% of
net revenues) in the year ended December 31, 1996 from $29.7 million (20.9% of
net revenues) in the year ended December 31, 1995. The increase was due
primarily to increased expenses associated with system expansions and the
provision of paging services to a greater number of subscribers. As existing
paging systems become more populated through the addition of new subscribers,
the fixed costs of operating these paging systems are spread over a greater
subscriber base. Annual service, rental and maintenance expenses per subscriber
decreased to $25 in the year ended December 31, 1996 from $28 in the year ended
December 31, 1995.

    Selling expenses increased to $50.7 million (16.7% of net revenues) in the
year ended December 31, 1996 from $24.5 million (17.3% of net revenues) in the
year ended December 31, 1995. The increase in selling expenses was due to the
addition of sales personnel to support continued growth in the subscriber base,
as the number of net new pagers in service resulting from internal growth
increased by 122.7% from the year ended December 31, 1995 to the year ended
December 31, 1996. Arch's selling cost per net new pager in service decreased to
$62 in the year ended December 31, 1996 from $67 in the year ended December 31,
1995, primarily due to increased sales through indirect distribution channels.
Most selling expenses are directly related to the number of net new subscribers
added. Therefore, such expenses may increase in the future if pagers in service
are added at a more rapid rate than in the past.

    General and administrative expenses increased to $82.5 million (27.1% of net
revenues) in the year ended December 31, 1996 from $40.4 million (28.5% of net
revenues) in the year ended December 31, 1995. The increase in absolute dollars
was due primarily to increased expenses associated with supporting more pagers
in service.

    Depreciation and amortization expenses increased to $191.9 million (63.1% of
net revenues) in the year ended December 31, 1996 from $60.2 million (42.5% of
net revenues) in the year ended December 31, 1995. These expenses reflect Arch's
acquisitions of paging businesses, accounted for as purchases, and continued
investment in pagers and other system expansion equipment to support continued
growth. As a result of its May 1996 acquisition of Westlink Holdings, Inc.
("Westlink"), which was accounted for under the purchase method of accounting,
Arch expects its depreciation and amortization expenses to increase by
approximately $19 million annually through the year ending December 31, 2003.

    Operating loss increased to $86.1 million in the year ended December 31,
1996 from $13.0 million in the year ended December 31, 1995 as a result of the
factors outlined above.

    Net interest expense increased to $75.9 million in the year ended December
31, 1996 from $22.5 million in the year ended December 31, 1995. The increase
was attributable to an increase in Arch's outstanding debt. Interest expense in
1996 includes approximately $24 million of non-cash interest accretion on the 10
7/8% Senior Discount Notes due 2008 under which semi-annual interest payments
commence on September 15, 2001. See Note 3 to Arch's Consolidated Financial
Statements. Arch expects its future interest expense to increase significantly
as a result of the additional debt incurred in connection with its May 1996
acquisition of Westlink.




                                       15
<PAGE>   16
    During the years ended December 31, 1996 and 1995, the Company recognized
income tax benefits of $51.2 million and $4.6 million, respectively,
representing the tax benefit of operating losses subsequent to the acquisitions
of USA Mobile Communications Holdings, Inc. ("USA Mobile") and Westlink which
were available to offset deferred tax liabilities arising from the Company's
acquisitions of USA Mobile in September 1995 and Westlink in May 1996. The
Company expects to recognize the $21.2 million balance of such tax benefits in
the year ending December 31, 1997.

    During 1996 and 1995, Arch recognized an extraordinary charge of $1.9
million and $1.7 million, respectively, representing the write-off of
unamortized deferred financing costs associated with the prepayment of
indebtedness under separate prior credit facilities.

    Net loss increased to $114.7 million in the year ended December 31, 1996
from $36.6 million in the year ended December 31, 1995 as a result of the
factors outlined above. Included in the net loss for the year ended December 31,
1995 was a charge of $4.0 million representing Arch's pro rata share of USA
Mobile's net loss for the period of time from Arch's acquisition of its initial
37% interest in USA Mobile on May 16, 1995 through the completion of Arch's
acquisition of USA Mobile on September 7, 1995. Included in the net loss for the
year ended December 31, 1996 was a charge of $2.0 million representing Arch's
pro rata share of Benbow PCS Ventures, Inc.'s ("Benbow") losses since May 21,
1996. The increases in depreciation and amortization expenses attributable to
the Company's September 1995 acquisition of USA Mobile and its May 1996
acquisition of Westlink, as described above, will increase the Company's future
net losses (or decrease its future net income, if any).

     EBITDA increased 124.2% to $105.8 million (34.8 % of net revenues) in
the year ended December 31, 1996 from $47.2 million (33.3% of net revenues) in
the year ended December 31, 1995 as a result of the factors outlined above.

    YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994

    Total revenues increased $86.7 million, or 114.2%, to $162.6 million in the
year ended December 31, 1995 from $75.9 million in the year ended December 31
1994 and net revenues increased $78.7 million, or 124.7%, from $63.1 million to
$141.8 million over the same period. Service, rental and maintenance revenues
increased $77.0 million, or 125.2%, to $138.5 million in the year ended December
31, 1995 from $61.5 million in the year ended December 31, 1994. These increases
in revenues were due primarily to the increase in the number of pagers in
service from 538,000 at December 31, 1994 to 2,006,000 at December 31, 1995.
Acquisitions of paging companies added 1,102,000 pagers in service during 1995,
with the remaining 366,000 pagers added through internal growth. Maintenance
revenues represented less than 10% of total service, rental and maintenance
revenues in the years ended December 31, 1994 and 1995. Product sales, less cost
of products sold, increased 110.7% to $3.3 million in the year ended December
31, 1995 from $1.6 million in the year ended December 31, 1994 as a result of a
greater number of pager unit sales.

    Service, rental and maintenance expenses increased to $29.7 million (20.9%
of net revenues) in the year ended December 31, 1995 from $14.4 million (22.8%
of net revenues) in the year ended December 31, 1994. The increase in absolute
dollars was due primarily to increased expenses associated with system
expansions and the provision of paging services to a greater number of
subscribers. The decrease as a percentage of revenues resulted from the increase
in Arch's subscriber base described above. Annual service, rental and
maintenance expenses per subscriber decreased to $28 in the year ended December
31, 1995 from $35 in the year ended December 31, 1994.

    Selling expenses increased to $24.5 million (17.3% of net revenues) in the
year ended December 31, 1995 from $11.5 million (18.3% of net revenues) in the
year ended December 31, 1994. The increase in selling expenses was due to the
addition of sales personnel to support continued growth in the subscriber base,
as the number of net new pagers in service resulting from internal growth
increased by 117.9% from the year ended December 31, 1994 to the year ended
December 31, 1995. Arch's selling cost per net new pager in service decreased to
$67 in the year ended December 31, 1995 from $69 in the year ended December 31,
1994.

    General and administrative expenses increased to $40.4 million (28.5% of net
revenues) in the year ended December 31, 1995 from $19.2 million (30.5% of net
revenues) in the year ended December 31, 1994. The increase in absolute dollars
was due primarily to increased expenses associated with supporting more pagers
in service.

    Depreciation and amortization expenses increased to $60.2 million (42.5% of
net revenues) in the year ended December 31, 1995 from $18.3 million (29.0% of
net revenues) in the year ended December 31, 1994. These expenses reflect Arch's
acquisitions of paging businesses, accounted for as purchases, and continued
investment in pagers and other system expansion equipment to support continued
growth.

    Operating loss increased to $13.0 million in the year ended December 31,
1995 from $0.4 million in the year ended December 31, 1994 as a result of the
factors outlined above.

    Net interest expense increased to $22.5 million in the year ended December
31, 1995 from $5.0 million in the year ended December 31, 1994. The increase was
attributable to an increase in Arch's outstanding debt and higher interest
rates.

    During the year ended December 31, 1995, the Company recognized an income
tax benefit of $4.6 million representing the tax benefit of operating losses
subsequent to September 7, 1995 which were available to offset deferred tax
liabilities arising from the Company's acquisition of USA Mobile.

    During the year ended December 31, 1995, Arch recognized an extraordinary
charge of $1.7 million, representing the write-off of unamortized deferred
financing costs associated with the prepayment of indebtedness under a prior
credit facility in May 1995. During the year ended December 31, 1994, Arch
recognized an extraordinary charge of $1.1 million, representing the write-off
of unamortized deferred financing costs associated with the prepayment of
indebtedness under a prior credit facility in September 1994.

    Net loss increased to $36.6 million in the year ended December 31, 1995 from
$6.5 million in the year ended December 31, 1994 as a result of the factors
outlined above. Included in the net loss for the year ended December 31, 1995
was a charge of $4.0 million representing Arch's pro rata share of USA Mobile's
net loss for the period of time from Arch's acquisition of its initial 37%
interest in USA Mobile on May 16, 1995 through the completion of Arch's
acquisition of USA Mobile on September 7, 1995.

    EBITDA increased 162.6% to $47.2 million (33.3% of net revenues) in the year
ended December 31, 1995 from $18.0 million (28.5% of net revenues) in the year
ended December 31, 1994 as a result of the factors outlined above.

    Four Months Ended December 31, 1994 Compared with Four Months Ended December
31, 1993

    Total revenues increased 44.7% to $28.0 million in the four months ended
December 31, 1994 from $19.4 million in the four months ended December 31, 1993
and net revenues increased 34.6% from $17.3 million to $23.3 million over the
same period. Service, rental and maintenance revenues increased 38.8% to $22.8
million in the four months ended December 31, 1994 from $16.5 million in the
four months ended December 31, 1993. These increases in revenues were due
primarily to the increase in the number of pagers in service from 288,000 at
December 31, 1993 to 538,000 at December 31, 1994. Maintenance revenues
represented less than 10% of total service, rental and maintenance revenues in
the four months ended December 31, 1993 and 1994. Product sales, less cost of
products sold, decreased to $0.5 million in the four months ended December 31,
1994 from $0.9 million in the four months ended December 31, 1993, due to
decreased margins on equipment sales which more than offset the increase in
product sales.

    Service, rental and maintenance expenses increased to $5.2 million (22.4% of
net revenues) in the four months ended December 31, 1994 from $4.0 million
(22.8% of net revenues) in the four months ended December 31, 1993. The increase
in absolute dollars was due primarily to increased expenses associated with
system expansions and the provision of paging services to a greater number of
subscribers. The decrease as a percentage of revenues resulted from the increase
in Arch's subscriber base described above. As existing paging systems become
more populated through the addition of new subscribers, the fixed costs of
operating these paging systems are spread over a greater subscriber base.
Annualized service, rental and maintenance expenses per subscriber decreased to
$33 in the four months ended December 31, 1994 from $44 in the four months ended
December 31, 1993.

    Selling expenses increased to $4.3 million (18.6% of net revenues) in the
four months ended December 31, 1994 from $3.1 million (17.6% of net revenues) in
the four months ended December 31, 1993. The increase in selling expenses was
due to the addition of sales personnel to support continued growth in the
subscriber base and a higher level of sales, as the number of net new pagers in
service resulting from internal growth nearly doubled from the four months ended
December 31, 1993 to the four months ended December 31, 1994. Despite the
increase in absolute dollars, Arch's selling cost per net new pager in service
decreased to $68 in the four months ended December 31, 1994, primarily due to
increased sales through indirect distribution channels, from $90 in the four
months ended December 31, 1993.

    General and administrative expenses increased to $7.0 million (30.1% of net
revenues) in the four months ended December 31, 1994 from $5.5 million (31.8% of
net revenues) in the four months ended December 31, 1993. The increase in
absolute dollars was due primarily to increased expenses associated with
supporting more pagers in service.

    Depreciation and amortization expenses increased to $6.9 million (29.5% of
net revenues) in the four months ended December 31, 1994 from $5.5 million
(32.0% of net revenues) in the four months ended December 31, 1993. These
expenses reflect Arch's acquisitions of paging businesses and continued
investment in pagers and other system expansion capital to support continued
growth.

    Operating loss decreased to $0.1 million in the four months ended December
31, 1994 from $0.7 million in the four months ended December 31, 1993 as a
result of the factors outlined above.

    Net interest expense increased to $2.0 million in the four months ended
December 31, 1994 from $1.1 million in the four months ended December 31, 1993.
The increase was attributable to an increase in Arch's outstanding debt and
higher interest rates.

    During the four months ended December 31, 1994, Arch recognized an
extraordinary charge of $1.1 million, representing the write-off of unamortized
deferred financing costs associated with the prepayment of indebtedness under a
prior credit facility in September 1994.

    Net loss increased to $3.3 million in the four months ended December 31,
1994 from $1.9 million in the four months ended December 31, 1993 as a result of
the factors outlined above.

    EBITDA increased 40.1% to $6.7 million (28.9% of net revenues) in the four
months ended December 31, 1994 from $4.8 million (27.8% of net revenues) in the
four months ended December 31, 1993 as a result of the factors outlined above.


LIQUIDITY AND CAPITAL RESOURCES

    Arch's business strategy requires the availability of substantial funds to
finance the expansion of existing operations, to fund capital expenditures for
pagers and paging system equipment, to finance acquisitions and to service debt.

    CAPITAL EXPENDITURES AND COMMITMENTS

    Excluding acquisitions of paging businesses, Arch's capital expenditures
increased from $33.5 million in the year ended December 31, 1994 to $60.5
million in the year ended December 31, 1995 and to $165.2 million in the year
ended December 31, 1996. To date, Arch has funded its capital expenditures with
net cash provided by operating activities, the issuance of equity securities and
the incurrence of debt.

    Arch has agreed, to the extent such funds are not available to Benbow from
other sources, to advance to Benbow sufficient funds to service debt obligations
incurred by Benbow in connection with its acquisition of its narrowband PCS
licenses and to finance build out of a regional narrowband PCS system. Arch
estimates that the total cost to Benbow of servicing such debt obligations and
constructing such regional narrowband PCS system will be approximately $75
million over the next five years.




                                       18
<PAGE>   19
    Arch currently anticipates capital expenditures of approximately $120
million to $130 million for the year ending December 31, 1997, primarily for the
purchase of pagers and paging system equipment. Such amounts are subject to
change based on the Company's internal growth rate and acquisition activity, if
any, during 1997. Arch believes that it will have sufficient cash available from
operations and credit facilities to fund these expenditures.

    ACQUISITIONS

    In May 1996, Arch completed its acquisition of Westlink for aggregate
consideration of $325.4 million in cash (including direct transaction costs).
See Note 2 to the Company's Consolidated Financial Statements.

    In September 1995, Arch completed its acquisition of USA Mobile for an
aggregate consideration of $582.2 million, consisting of $88.9 million in cash
(including direct transaction costs), 7,599,493 shares of common stock valued at
$209.0 million on the date of completion and the assumption of liabilities of
$284.3 million, including $241.2 million of long-term debt. See Note 2 to the
Company's Consolidated Financial Statements.

    During 1995, the Company also completed five additional acquisitions for
aggregate consideration of $36.1 million in cash plus the issuance of 395,000
shares of common stock valued at $6.9 million on the date of completion. See
Note 2 to the Company's Consolidated Financial Statements.

    The Company has pursued and intends to continue to pursue acquisitions of
paging businesses as part of its growth strategy. As a result, the Company
evaluates acquisition opportunities on an ongoing basis and from time to time is
engaged in discussions with respect to possible acquisitions.

    SOURCES OF FUNDS

    Arch's net cash provided by operating activities was $14.2 million, $14.7
million and $37.8 million in the years ended December 31, 1994, 1995 and 1996,
respectively.

    Arch believes that its capital needs for the foreseeable future will be
funded with borrowings under current and future credit facilities, net cash
provided by operations and, depending on the Company's needs and market
conditions, possible sales of equity or debt securities. For additional 
information, see Note 3 to the Company's Consolidated Financial Statements.

INFLATION

    Inflation has not had a material effect on Arch's operations to date. Paging
systems equipment and operating costs have not increased in price and Arch's
pager costs have declined substantially in recent years. This reduction in costs
has generally been reflected in lower pager prices charged to subscribers who
purchase their pagers. Arch's general operating expenses, such as salaries,
employee benefits and occupancy costs, are subject to normal inflationary
pressures.

FACTORS AFFECTING FUTURE OPERATING RESULTS

    The following important factors, among others, could cause the Company's
actual operating results to differ materially from those indicated or suggested
by forward-looking statements made in this Form 10-K or presented elsewhere by
the Company's management from time to time.

    INDEBTEDNESS AND HIGH DEGREE OF LEVERAGE

    The Company is highly leveraged. At December 31, 1996, the Company has
outstanding $918.2 million of total debt, including: (i) $299.3 million accreted
value of the 10 7/8% Senior Discount Notes due 2008; (ii) $125 million principal
amount of the 9-1/2% Senior Notes due 2004 of USA Mobile II; (iii) $100 million
principal amount of the 14% Senior Notes due 2004 of USA Mobile II; (iv) $327.5
million borrowed under the Arch Enterprises Credit Facility; (v) $53.0 million
borrowed under the USA Mobile II Credit Facility; and (vi) $13.4 million
principal amount of the Company's 6-3/4% Convertible Subordinated Debentures due
2003. The ability of the Company to make payments of principal and interest on
its indebtedness will be dependent upon the Company's subsidiaries achieving and
sustaining levels of performance in the 



                                       19
<PAGE>   20
future that will permit such subsidiaries to pay sufficient dividends,
distributions or fees to the Company. Many factors, some of which will be beyond
the Company's control, such as prevailing economic conditions, will affect the
performance of the Company and its subsidiaries. In addition, covenants imposed
by the current and future credit facilities and other indebtedness of the
Company and its subsidiaries will restrict the ability of the Company and its
subsidiaries to incur additional indebtedness and prohibit certain activities
and may limit other aspects of the Company's operations. There can be no
assurance that the Company or its subsidiaries will be able to generate
sufficient cash flow to cover required interest and principal payments on their
current and future indebtedness. If the Company is unable to meet interest and
principal payments in the future, it may, depending upon the circumstances which
then exist, seek additional equity or debt financing, attempt to refinance its
existing indebtedness or sell all or part of its business or assets to raise
funds to repay its indebtedness. There can be no assurance that sufficient
equity or debt financing will be available or, if available, that it will be on
terms acceptable to the Company, that the Company will be able to refinance its
existing indebtedness or that sufficient funds could be raised through asset
sales. The Company's high degree of leverage may have important consequences for
the Company, including: (i) the ability of the Company and its subsidiaries to
obtain additional financing for acquisitions, working capital, capital
expenditures or other purposes, if necessary, may be impaired or such financing
may not be on favorable terms; (ii) a substantial portion of the cash flow of
the Company's subsidiaries will be used to pay interest expense, which will
reduce the funds which would otherwise be available for operations and future
business opportunities; (iii) the Company may be more highly leveraged than its
competitors which may place it at a competitive disadvantage; and (iv) the
Company's high degree of leverage will make it more vulnerable to a downturn in
its business or the economy generally.

    FUTURE CAPITAL NEEDS

    The Company's business strategy requires the availability of substantial
funds to finance the continued development and future growth and expansion of
its operations, including possible acquisitions. The amount of capital required
by the Company will depend upon a number of factors, including subscriber
growth, technological developments, marketing and sales expenses, competitive
conditions, acquisition strategy and acquisition opportunities. No assurance can
be given that additional equity or debt financing will be available to the
Company on acceptable terms, if at all. The unavailability of sufficient
financing when needed would have a material adverse effect on the Company.

    HISTORY OF LOSSES

    The Company has not reported any net income since its inception. The Company
reported net losses of $6.5 million, $36.6 million and $114.7 million in the
years ended December 31, 1994, 1995 and 1996, respectively. These net losses
have resulted principally from (i) substantial depreciation and amortization
expenses, primarily related to intangible assets and pager depreciation, and
(ii) interest expense on debt incurred primarily to finance acquisitions of
paging operations and other costs of growth. Substantial and increased amounts
of debt are expected to be outstanding for the foreseeable future, which will
result in significant additional interest expense which could have a substantial
negative impact on the Company. The Company expects to continue to report net
losses for the foreseeable future. The Company also expects that its
depreciation and amortization expenses will increase by approximately $19
million annually through the year ending December 31, 2003 as a result of its
May 1996 acquisition of Westlink. Such increased depreciation and amortization
expenses will increase the Company's future net losses (or decrease its future
net income, if any).

    GROWTH AND ACQUISITION STRATEGY

    The Company has pursued and intends to continue to pursue acquisitions of
paging businesses as well as the continued internal growth of the Company's
paging business. The process of integrating acquired paging businesses may
involve unforeseen difficulties and may require a disproportionate amount of the
time and attention of the Company's management and the financial and other
resources of the Company. No assurance can be given that suitable additional
acquisitions can be identified, financed and completed on acceptable terms, or
that the Company's future acquisitions will be successful. Implementation of the
Company's growth strategies will be subject to numerous other contingencies
beyond the control of the Company, including general and regional economic
conditions, interest rates, competition, changes in regulation or technology and
the ability to attract and retain skilled employees. Accordingly, no assurance
can be given that the Company's growth strategies will prove effective or that
the goals of the Company will be achieved.




                                       20
<PAGE>   21
    DEPENDENCE ON KEY PERSONNEL

    The success of the Company will be dependent, to a significant extent, upon
the continued services of a relatively small group of executive personnel. The
Company does not have employment agreements with any of its current executive
officers, although all current executive officers have entered into
non-competition agreements with the Company. The loss or unavailability of one
or more of its executive officers or the inability to attract or retain key
employees in the future could have an adverse effect upon the Company's
operations.

    COMPETITION AND TECHNOLOGICAL CHANGE

    The Company faces competition from other paging service providers in all
markets in which it operates as well as from certain competitors who hold
nationwide licenses. The Company believes that competition for paging
subscribers is based on quality of service, geographic coverage and price and
that the Company generally competes effectively based on these factors. Monthly
fees for basic paging services have, in general, declined since the Company
commenced operations in September 1986, due in part to competitive conditions,
and the Company may face significant price-based competition in the future which
could adversely affect the Company. Some of the Company's competitors possess
greater financial, technical and other resources than the Company. A trend
towards increasing consolidation in the paging industry in particular and the
wireless communications industry in general in recent years has led to
competition from increasingly larger and better capitalized competitors. If any
of such competitors were to devote additional resources to the paging business
or focus its strategy on the Company's markets, the Company's results of
operations could be adversely affected. A variety of wireless two-way
communication technologies currently are in use or under development. Although
such technologies generally are higher priced than paging services or not widely
available, technological improvements could result in increased capacity and
efficiency for wireless two-way communication and, accordingly, could result in
increased competition for the Company. Two-way service providers also could
elect to provide paging service as an adjunct to their primary services. Future
technological advances in the telecommunications industry could increase new
services or products competitive with the paging services provided by the
Company or could require the Company to reduce the price of its paging services
or incur additional capital expenditures to meet competitive requirements.
Recent and proposed regulatory changes by the FCC are aimed at encouraging such
technological advances and new services. For example, the FCC has created
potential sources of competition by opening up new spectrum for such services as
the General Wireless Communications Service ("GWCS") and the Wireless
Communications Service ("WCS") as well as speeding up licensing of other
services through auctions, including the Local Multipoint Distribution Service
("LMDS"), 220-222 MHz and broadband PCS services. Entities offering service on
wireless two-way communications technology, including cellular telephones and
specialized mobile radio services, also compete with the paging services that
the Company provides. There can be no assurance that the Company will be able to
compete successfully with its current and future competitors in the paging
business or with competitors offering alternative communication technologies.

    SUBSCRIBER TURNOVER

    The results of operations of wireless messaging service providers, such as
the Company, can be significantly affected by subscriber cancellations. The
sales and marketing costs associated with attracting new subscribers are
substantial relative to the costs of providing service to existing customers.
Because the paging business is characterized by high fixed costs,
disconnection's directly and adversely affect operating cash flow. An increase
in its subscriber cancellation rate may adversely affect the Company's results
of operations.




                                       21
<PAGE>   22
    DEPENDENCE ON SUPPLIERS

    The Company does not manufacture any of the pagers used in its paging
operations. The Company buys pagers primarily from Motorola, Inc. ("Motorola")
and NEC America, Inc. ("NEC") and therefore is dependent on such manufacturers
to obtain sufficient pager inventory for new subscriber and replacement needs.
In addition, the Company purchases terminals and transmitters primarily from
Glenayre Technologies, Inc. ("Glenayre") and Motorola and thus is dependent on
such manufacturers for sufficient terminals and transmitters to meet its
expansion and replacement requirements. To date, the Company has not experienced
significant delays in obtaining pagers, terminals or transmitters, but there can
be no assurance that the Company will not experience such delays in the future.
The Company has never had a purchase agreement with Glenayre or NEC. The
Company's purchase agreement with Motorola expires in December 1997, with a
provision for automatic renewal for a one-year term. Although the Company
believes that sufficient alternative sources of pagers, terminals and
transmitters exist, there can be no assurance that the Company would not be
adversely affected if it were unable to obtain these items from current supply
sources or on terms comparable to existing terms.

    GOVERNMENT REGULATION, FOREIGN OWNERSHIP AND POSSIBLE REDEMPTION

    The paging operations of the Company are subject to regulation by the FCC
and various state regulatory agencies. There can be no assurance that those
agencies will not propose or adopt regulations or take actions that would have a
material adverse effect on the Company's business. Changes in regulation of the
Company's paging business or the allocation of radio spectrum for services that
compete with the Company's business could adversely affect the Company's results
of operations. Indeed, the FCC has created potential sources of competition by
opening up new spectrum for such services as the GWCS and the WCS as well as,
speeding up licensing of other services through auctions, including the LMDS,
220-222 MHz and broadband PCS services. Further, the FCC has recently adopted
rules implementing a market area licensing scheme. In addition, some aspects of
the recently enacted Telecommunications Act of 1996 could have a beneficial
effect on Arch's business, but other provisions may place additional burdens
upon Arch or subject Arch to increased competition. The Communications Act of
1934, as amended, limits foreign ownership of entities that hold certain
licenses from the FCC. Because the Company, through its subsidiaries, holds FCC
licenses, in general, no more than 25% of the Company's stock can be owned or
voted by aliens or their representatives, a foreign government or its
representative or a foreign corporation, the Company's Restated Certificate of
Incorporation permits the redemption of shares of the Company's capital stock
from foreign stockholders where necessary to protect the Company's regulatory
licenses, but such redemption would be subject to the availability of capital to
the Company and any restrictions contained in the debt instruments of the
Company and under Delaware law. The failure to redeem such shares promptly could
jeopardize the Company's FCC licenses.

    The financial statements and schedules listed in Item 14(a)(1) and (2) are
included in this Report beginning on Page F-1.


ITEM 9.       CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
              FINANCIAL DISCLOSURE

    On September 7, 1995, the Board of Directors of Arch, including the members
of its Audit Committee, approved the engagement of Arthur Andersen LLP as
Arch's  independent accountants to replace the firm of Price Waterhouse LLP,
whose engagement as independent accountants of USA Mobile was terminated upon
the completion of Arch's acquisition of USA Mobile. Prior to September 7, 1995,
Arthur Andersen LLP served as Arch's independent accountants and Price
Waterhouse LLP served as USA Mobile's independent accountants. The reports of
Price Waterhouse LLP on USA Mobile's financial statements for the years ended
December 31, 1993 and December 31, 1994 did not contain an adverse opinion or a
disclaimer of opinion and were not qualified as to uncertainty, audit scope or
accounting principles.

    During USA Mobile's years ended December 31, 1993 and December 31, 1994 and
through September 7, 1995, (i) there were no disagreements between USA Mobile
and Price Waterhouse LLP on any matter of accounting principles or
practices, financial statement disclosure or auditing scope or procedure which
disagreements, if not resolved  to the satisfaction of Price Waterhouse LLP,
would have caused it to make a reference to the subject matter of the
disagreement in connection with its report, and (ii) USA Mobile did not consult
Arthur Andersen LLP regarding (a) the application of accounting principles to a
specified transaction either completed or proposed, (b) the type of audit
opinion that might be rendered on USA Mobile's financial statements or (c)
items which concerned the subject matter of any disagreement with Price
Waterhouse LLP or reportable events as described in subparagraph (a) (2) of
Item 304 of Regulation S-K under the Exchange Act.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Arch Communications Group, Inc.:

    We have audited the accompanying consolidated balance sheets of Arch
Communications Group, Inc. (a Delaware corporation) (the "Company") and
subsidiaries as of December 31, 1995 and 1996 and the related consolidated
statements of operations, stockholders' equity (deficit) and cash flows for the
year ended August 31, 1994, for the four months ended December 31, 1994 and each
of the two years in the period ended December 31, 1996. These consolidated
financial statements and the schedule referred to below are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these consolidated financial statements and schedule based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Arch Communications Group,
Inc. and subsidiaries as of December 31, 1995 and 1996 and the results of their
operations and their cash flows for the year ended August 31, 1994, for the four
months ended December 31, 1994 and each of the two years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

    Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index at Item
14(a)(2) is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in our audits of
the basic financial statements and, in our opinion, fairly states, in all
material respects, the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.



                                                             ARTHUR ANDERSEN LLP

                         ARCH COMMUNICATIONS GROUP, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

    Organization -- Arch Communications Group, Inc. ("Arch") is a leading
provider of wireless messaging services, primarily paging services.

    Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of Arch and its wholly-owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated.

    Revenue Recognition -- Arch recognizes revenue under rental and service
agreements with customers as the related services are performed. Maintenance
revenues and related costs are recognized ratably over the respective terms of
the agreements. Sales of equipment are recognized upon delivery. Commissions are
recognized as an expense when incurred.

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

    Cash Equivalents -- Cash equivalents include short-term, interest-bearing
instruments purchased with remaining maturities of three months or less. The
carrying amount approximates fair value due to the relatively short period to
maturity of these instruments.

    Inventories -- Inventories consist of new pagers which are held specifically
for resale. Inventories are stated at the lower of cost or market, with cost
determined on a first-in, first-out basis.

    Property and Equipment -- Effective October 1, 1995, Arch changed its
estimate of the useful life of pagers from four years to three years. This
change was made to better reflect the estimated period during which pagers will
produce equipment rental revenue. The change did not have a material effect on
depreciation expense or net loss in the quarter ended December 31, 1995.

    Pagers sold or otherwise retired are removed from the accounts at their net
book value using the first-in, first-out method.

    Property and equipment is stated at cost and is depreciated using the
straight-line method over the following estimated useful lives:

$87,450,000 for the year ended August 31, 1994, the four months ended December
31, 1993 and 1994, and the years ended December 31, 1995 and 1996, respectively.

    Amortization expense related to intangible and other assets totaled
$5,720,000, $2,058,000 (unaudited), $2,233,000, $35,171,000 and $104,421,000 for
the year ended August 31, 1994, the four months ended December 31, 1993 and 1994
and the years ended December 31, 1995 and 1996, respectively.

    Subscriber lists, Federal Communications Commission ("FCC") licenses and
goodwill are amortized over their estimated useful lives, ranging from five to
ten years using the straight-line method. Non-competition agreements are
amortized over the terms of the agreements using the straight-line method. Other
assets consist of contract rights, organizational and FCC application and
development costs which are amortized using the straight-line method over their
estimated useful lives not exceeding ten years. Development costs include
nonrecurring, direct costs incurred in the development and expansion of paging
systems, and are amortized over a two-year period.

    Deferred financing costs incurred in connection with Arch's credit
agreements (see Note 3) are being amortized over periods not to exceed the terms
of the related agreements. As credit agreements are amended or renegotiated,
unamortized deferred financing costs are written-off as an extraordinary charge.
For the four months ended December 31, 1994, a charge of $1,137,000 was
recognized, a charge of $1,684,000 was recognized in the second quarter of 1995
in connection with the closing of a new credit facility and a charge of
$1,904,000 was recognized in the second quarter of 1996 in connection with the
closing of another new credit facility.

    On November 8, 1994, CONXUS Communications, Inc. ("CONXUS"), formerly PCS
Development Corporation, was successful in acquiring the rights to a two-way
paging license in five designated regions in the United States in the FCC
narrowband wireless spectrum auction. As of December 31, 1996 Arch's investment
in CONXUS totaled $6.5 million representing an equity interest of 10.5%
accounted for under the cost method.

    In connection with Arch's May 1996 acquisition of Westlink Holdings, Inc.
("Westlink") (see Note 2), Arch acquired Westlink's 49.9% share of the capital
stock of Benbow PCS Ventures, Inc. ("Benbow"). Benbow has exclusive rights to a
50kHz outbound/12.5kHz inbound narrowband personal communications license in
each of the central and western regions of the United States. Arch has agreed,
to the extent such funds are not available to Benbow from other sources, to
advance Benbow sufficient funds to build out its narrowband personal
communications system. Arch's investment in Benbow is accounted for under the
equity method whereby Arch's share of Benbow's losses since the acquisition date
of Westlink are recognized in Arch's accompanying consolidated statements of
operations under the caption equity in loss of affiliate.

    In accordance with Statement of Financial Accounting Standards ("SFAS") No.
121 "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to
be Disposed of" Arch evaluates the recoverability of its carrying value of the
Company's long-lived assets and certain intangible assets based on estimated
undiscounted cash flows to be generated from each of such assets as compared to
the original estimates used in measuring the assets. To the extent impairment is
identified, Arch reduces the carrying value of such impaired assets. To date,
Arch has not had any such impairments.

      Fair Value of Financial Instruments -- Arch's financial instruments, as
defined under SFAS No. 107 "Disclosures about Fair Value of Financial
Instruments", include its cash, its debt financing and interest rate protection
agreements. The fair value of cash is equal to the carrying value at December
31, 1995 and 1996.




                                      F-8
<PAGE>   34
    As discussed in Note 3, Arch's debt financing primarily consists of (1)
senior bank debt, (2) fixed rate senior notes and (3) convertible subordinated
debentures. Arch considers the fair value of senior bank debt to be equal to the
carrying value since the related facilities bear a current market rate of
interest. Arch is unable to determine the fair value of the convertible
subordinated debentures due to the specific terms and conversion features
available in their respective agreements. These various facilities were
negotiated with the creditors based on the facts and circumstances available at
the time the debt was incurred. Since Arch has undergone significant change over
the past year, management is unable to determine what rates and terms would be
available currently.

    Arch's fixed rate senior notes are traded publicly. The following table
depicts the fair value of this debt based on the current market quote as of
December 31, 1995 and 1996 (in thousands):

</TABLE>

    At December 31, 1996 Arch had off balance sheet interest rate protection
agreements consisting of interest rate swaps and interest rate caps with
notional amounts of $165.0 million and $55.0 million, respectively. The fair
values of the interest rate swaps and interest rate caps at December 31, 1996
were $361,000 and $10,000, respectively.

    Net Income (Loss) Per Common Share -- Net income (loss) per common share is
based on the weighted average number of common shares outstanding. Shares of
stock issuable pursuant to stock options and upon conversion of the subordinated
debentures (see Note 3) have not been considered, as their effect would be
anti-dilutive. In February 1997, the Financial Accounting Standards Board issued
SFAS No. 128 "Earnings Per Share". The Company intends to adopt this standard in
1997. The adoption of this standard is not expected to have an effect on the
Company's financial position or results of operations.

    Unaudited Interim Consolidated Financial Statements -- The consolidated
statements of operations and cash flows for the four months ended December 31,
1993 are unaudited and, in the opinion of Arch's management, include all
adjustments, consisting of normal, recurring adjustments, necessary for a fair
presentation of Arch's consolidated financial position, results of operations
and cash flows. The results of operations for the four months ended December 31,
1993 are not necessarily indicative of the results for any other period.

    Change in Year End -- In October 1994, Arch changed its fiscal year end from
August 31 to December 31. Arch's quarterly and annual reporting is now based on
Arch's fiscal year end of December 31.

    Reclassifications -- Certain amounts of prior periods were reclassified to
conform with the 1996 presentation.

2.  ACQUISITIONS

    During the year ended August 31, 1994, Arch acquired a paging system located
in Rhode Island for approximately $3,325,000.

    During the four months ended December 31, 1994, Arch acquired, in separate
transactions, the paging assets of a system located in Florida and the stock of
a paging company located in Illinois and Wisconsin for an aggregate purchase
price of approximately $31 million including 900,000 shares of Arch common stock
valued at $15.9 million. In connection with the stock acquisition, the fair
value of assets acquired was approximately $33 million, less liabilities assumed
of approximately $2 million. In December 1994, Arch purchased certain paging
system assets and frequencies from BellSouth Telecommunications, Inc. for
approximately $500,000 in cash.

    On September 7, 1995, Arch completed its acquisition of USA Mobile
Communications Holdings, Inc. ("USA Mobile"). The acquisition was completed in
two steps. First, in May 1995, Arch acquired approximately 37%, or 5,450,000
shares, of USA Mobile's then outstanding common stock for $83.9 million in cash,
funded by borrowings under the Arch Enterprises Credit Facility (see Note 3).
Accordingly, Arch accounted for its investment in USA Mobile under the equity
method of accounting. Arch recorded a charge of $4.0 million for the year ended
December 31, 1995 representing it's pro rata share of USA Mobile's net loss from
May until the acquisition was completed. Second, on September 7, 1995, the
acquisition was completed through the merger of Arch with and into USA Mobile
("the Merger"). Upon consummation of the Merger, USA Mobile was renamed Arch
Communications Group, Inc. In the Merger, each share of USA Mobile's outstanding
common stock was exchanged for Arch common stock on a .8020-for-one basis (an
aggregate of 7,599,493 shares of Arch common stock) and the 5,450,000 USA Mobile
shares purchased by Arch in May 1995 were retired. Outstanding shares of USA
Mobile's Series A Redeemable Preferred Stock were not affected by the Merger
(see Note 4). Arch is treated as the acquirer in the Merger for accounting and
financial reporting purposes and the purchase price was allocated based upon the
fair market values of assets acquired and liabilities assumed. The aggregate
consideration paid or exchanged in the Merger was $582.2 million, consisting of
cash paid of $88.9 million, including direct transaction costs, 7,599,493 shares
of Arch common stock valued at $209.0 million and the assumption of liabilities
of $284.3 million, including $241.2 million of long-term debt.

    During the year ended December 31, 1995, Arch completed five acquisitions of
paging companies, in addition to the Merger, for purchase prices aggregating
approximately $43.0 million, consisting of cash of $36.1 million and 395,000
shares of Arch common stock valued at $6.9 million. Goodwill resulting from the
acquisitions and the Merger is being amortized over a ten-year period using the
straight-line method.

    On May 21, 1996, Arch completed its acquisition of all the outstanding
capital stock of Westlink for $325.4 million in cash, including direct
transaction costs. The purchase price was allocated based on the fair values of
assets acquired and liabilities assumed (including deferred income taxes arising
in purchase accounting), which amounted to $383.6 million and $58.2 million,
respectively.

    These acquisitions have been accounted for as purchases, and the results of
their operations have been included in the consolidated financial statements
from the dates of the respective acquisitions. The following unaudited pro forma
summary presents the consolidated results of operations as if the acquisitions
had occurred at the beginning of the periods presented, after giving effect to
certain adjustments, including depreciation and amortization of acquired assets
and interest expense on acquisition debt. These pro forma results have been
prepared for comparative purposes only and do not purport to be indicative of
what would have occurred had the acquisitions been made at the beginning of the
period presented, or of results that may occur in the future.

    Senior Bank Debt -- Arch, through its operating subsidiaries, has entered
into two credit agreements. Arch Communications Enterprises, Inc. ("Arch
Enterprises"), a wholly-owned subsidiary of Arch, and Arch have entered into a
credit agreement with a group of banks and financial institutions who have
agreed, subject to certain terms and conditions set forth in the agreement, to
provide (i) a $250 million, seven-year reducing revolver facility (the "Arch
Enterprises Revolver"), (ii) a $150 million, seven-year term loan (the "Tranche
A Term Loan"), and (iii) a $100 million, eight-year term loan (the "Tranche B
Term Loan"). The Arch Enterprises Revolver, Tranche A Term Loan and Tranche B
Term Loan are collectively referred to as the Arch Enterprises Credit Facility.
Arch and the operating subsidiaries of Arch Enterprises have guaranteed all
obligations under the Arch Enterprises Credit Facility.

    USA Mobile Communications, Inc. II ("USA Mobile II"), a wholly owned
subsidiary of Arch and the direct subsidiaries of USA Mobile II (the "USA Mobile
II Borrowing Subsidiaries") are parties to a Credit Agreement dated September 8,
1995, as amended, with a bank and other lenders establishing the USA Mobile II
Credit Facility. Under the USA Mobile II Credit Facility, a bank and the other
lenders have agreed to advance up to $60 million to the USA Mobile II Borrowing
Subsidiaries for working capital purposes under a reducing revolving credit
facility. Upon the closing of the USA Mobile II Credit Facility, the bank and
the other lenders did not require the contemporaneous grant of a security
interest in the assets of USA Mobile II and its subsidiaries but they have
reserved the right to require such a security interest upon the occurrence of
certain triggering events. Arch and USA Mobile II have guaranteed the
obligations of the USA Mobile II Borrowing Subsidiaries under the USA Mobile II
Credit Facility. Arch's guarantee is secured by the pledge of the stock of Arch
Enterprises and USA Mobile II.

    In March 1997, the USA Mobile II Borrowing Subsidiaries entered into a new
credit agreement, pursuant to which the lenders have agreed, subject to certain
terms and conditions set forth in the agreement, to provide a $110 million
five-year reducing revolving credit facility (the "1997 USA Mobile II Credit
Facility") which replaces the existing USA Mobile Credit Facility. The terms of
the 1997 USA Mobile II Credit Facility are substantially the same as the USA
Mobile II Credit Facility except that scheduled mandatory reductions commence on
June 30, 2000.

    The Arch Enterprises Credit Facility and the USA Mobile II Credit Facility
are subject to scheduled mandatory reductions commencing on December 31, 1999
and December 31, 1998, respectively. The Tranche A Term Loan and Tranche B Term
Loan will be amortized in quarterly installments commencing on March 31, 1998.
Availability under the Arch Enterprises Credit Facility and USA Mobile II Credit
Facility also is reduced to the extent that Arch Enterprises or USA Mobile II
receives proceeds, above a specified limit, from the sale of assets outside the
ordinary course of business or insurance proceeds that are not used to repair or
replace damaged property. The Tranche A Term Loan and Tranche B Term Loan and
USA Mobile II Credit Facility also are reduced to the extent that the cash flow
of Arch Enterprises or USA Mobile II exceeds certain levels.

    Except for the Tranche B Term Loan, borrowings under the Credit Facilities
bear interest based on a reference rate equal to either (i) the bank's Alternate
Base Rate, or (ii) the bank's LIBOR rate, in each case plus a margin which is
based on the ratio of total debt to annualized operating cash flow. Borrowings
under the Tranche B Term Loan bear interest at either the bank's Alternate Base
Rate plus 1.75%, or the bank's LIBOR rate plus 3.00%. Interest is payable
quarterly in arrears. Arch Enterprises is required to maintain interest rate
protection on at least 50% of outstanding borrowings under the Arch Enterprises
Credit Facility, and has entered into interest rate swap and interest rate cap
agreements. Entering into interest rate cap and swap agreements involves both
the credit risk of dealing with counterparties and their ability to meet the
terms of the contracts and interest rate risk. The notional principal amount of
the interest rate swaps outstanding were $165 million at December 31, 1996. The
weighted average fixed payment rate was 5.839% while the weighted average rate
of variable interest payments under the Arch Enterprises Credit Facility was
5.544% at December 31, 1996. The total notional values of the interest rate cap
agreements were $55 million with cap levels between 7% and 8% at December 31,
1996. In the event of non-performance by the counterparty to these interest rate
protection agreements, Arch Enterprises would be subject to the prevailing
interest rates specified in the Arch Enterprises Credit Facility.

    The interest rate cap agreements will pay the Company the difference between
LIBOR and the cap level if LIBOR exceeds the cap levels at any of the quarterly
reset dates. If LIBOR remains below the cap level, no payment is made to the
Company. The transaction fees for these instruments are being amortized over the
terms of the agreements.

    Under the interest rate swap agreements, the Company will pay the difference
between LIBOR and the fixed swap rate if the swap rate exceeds LIBOR, and the
Company will receive the difference between LIBOR and the fixed swap rate if
LIBOR exceeds the swap rate. Settlement occurs on the quarterly reset dates
specified by the terms of the contracts. At December 31, 1995 and 1996, the
Company had a net payable of $26,000 and $124,000, respectively, on the interest
rate swaps.

    The Arch Enterprises Credit Facility and the USA Mobile II Credit Facility
each require payment of a fee of .375% per annum on the daily average available
revolving commitment, depending on the ratio of total debt to annualized
operating cash flow, and an annual agency fee of $50,000 and $35,000,
respectively.

    The Arch Enterprises Credit Facility is secured by all of the assets of the
operating subsidiaries of Arch Enterprises and the pledge of all of the stock of
Arch's direct and indirect subsidiaries. The lenders in the USA Mobile II Credit
Facility have reserved the right to require the grant of a security interest in
the assets of USA Mobile II and its subsidiaries upon the occurrence of an event
of default under the USA Mobile II Credit Facility.

    The Credit Facilities contain restrictions that limit, among other things,
additional indebtedness and encumbrances on assets, mergers and sales of assets;
repurchase or redemption of capital stock; capital expenditures; acquisitions
that exceed certain dollar limitations without the lenders prior approval; and
prepayment of indebtedness other than indebtedness under the Credit Facilities.
The Credit Facilities also, in effect, prohibit the payment of cash dividends.
Additionally, the Credit Facilities require that Arch Enterprises and USA Mobile
II meet certain financial covenants, including covenants with respect to ratios
of cash flow to fixed charges, cash flow to debt service, cash flow to interest
service and total indebtedness to cash flow. As of December 31, 1996, both Arch
Enterprises and USA Mobile II were in compliance with the covenants of their
respective credit agreements.

    At December 31, 1996, Arch Enterprises had outstanding borrowings of $327.5
million under the Arch Enterprises Credit Facility at a weighted average annual
interest rate of 8.35%, and USA Mobile II had outstanding borrowings of $53.0
million under the USA Mobile II Credit Facility at a weighted average annual
interest rate of 8.51%. At December 31, 1996, $9.5 million was available under
the Arch Enterprises Credit Facility and $7.0 million was available under the
USA Mobile II Credit Facility.

    Senior Notes - On March 12, 1996, Arch completed a public offering of 10
7/8% Senior Discount Notes due 2008 (the "Senior Discount Notes") in the
aggregate principal amount at maturity of $467.4 million ($275.0 million initial
accreted value). Interest does not accrue on the Senior Discount Notes prior to
March 15, 2001. Commencing September 15, 2001, interest on the Senior Discount
Notes is payable semi-annually at an annual rate of 10 7/8%. The $266.1 million
net proceeds from the issuance of the Senior Discount Notes, after deducting
underwriting discounts and commissions and offering expenses, were used
principally to fund a portion of the purchase price of Arch's acquisition of
Westlink (see Note 2). Prior to the completion of the Westlink acquisition, Arch
used $225.0 million of the net proceeds to repay existing indebtedness under
Arch's credit facilities with the remainder primarily invested in short-term,
interest-bearing instruments.

    The completion of the Merger (see Note 2) constituted a "change in control"
of USA Mobile II under the Indenture relating to the USA Mobile II 14% Notes. On
October 6, 1995, USA Mobile II commenced an offer to permit the holders of the
USA Mobile II 14% Notes to sell them to USA Mobile II, in whole or in part, at a
price in cash equal to 102% of the principal amount thereof. The offer to
purchase the USA Mobile II 14% Notes expired on November 6, 1995 with none of
the USA Mobile II 14% Notes being tendered. No redemption offer is required or
will be made as a result of the Merger for the USA Mobile II 9-1/2% Notes.

    The Senior Discount Notes and the Senior Notes contain certain restrictive
covenants which, among other things, limit the ability of Arch or USA Mobile II
to: incur additional indebtedness; pay dividends; redeem capital stock or
subordinated debt; make certain investments; grant liens on its assets; sell
assets; enter into transactions with related parties; and merge, consolidate or
transfer substantially all of its assets, under certain circumstances.

    Convertible Subordinated Debentures - On March 6, 1996, the holders of $14.1
million principal amount of Arch's 6-3/4% Convertible Subordinated Debentures
due 2003 ("Arch Convertible Debentures") elected to convert their Arch
Convertible Debentures into Arch common stock at a conversion price of $16.75
per share and received approximately 843,000 shares of Arch common stock
together with a $1.6 million cash premium.

    Interest on the remaining outstanding Arch Convertible Debentures is payable
semiannually on June 1 and December 1. The Arch Convertible Debentures are
unsecured and are subordinated to all existing indebtedness of Arch.

    The Arch Convertible Debentures are redeemable on or after December 1, 1997,
at the option of Arch, in whole or in part, at certain prices declining annually
to 100% of the principal amount at maturity plus accrued interest. The Arch
Convertible Debentures also are subject to redemption at the option of the
holders, at a price of 100% of the principal amount plus accrued interest, upon
the occurrence of certain events.

    The Arch Convertible Debentures are convertible at their principal amount
into shares of Arch's common stock at any time prior to redemption or maturity
at an initial conversion price of $16.75 per share, subject to adjustment.

    Maturities of Debt -- Scheduled long-term debt maturities at December 31,
1996, as adjusted by the 1997 USA Mobile II Credit Facility, are as follows (in
thousands):

4.  REDEEMABLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY

    Redeemable Preferred Stock -- In connection with the Merger (see Note 2),
Arch assumed the obligations associated with 22,530 outstanding shares of Series
A Redeemable Preferred Stock issued by USA Mobile. The preferred stock is
recorded at its accreted redemption value, based on 10% annual accretion through
the redemption date. On January 30, 1997 all outstanding preferred stock was
redeemed for $3,744,000 in cash.




                                      F-13

    Stock Options -- Arch has a 1989 Stock Option Plan (the "1989 Plan") which
provides for the grant of incentive and nonqualified stock options to key
employees, directors and consultants to purchase Arch's common stock. Incentive
stock options are granted at exercise prices not less than the fair market value
on the date of grant. The 1989 Plan provides for the granting of options to
purchase a total of 1,128,944 shares of common stock. Options generally vest
over a five-year period from the date of grant with the first such vesting (20%
of granted options) occurring one year from the date of grant and continuing
ratably at 5% on a quarterly basis thereafter. However, in certain
circumstances, options may be immediately exercised in full. Options generally
have a duration of 10 years. All outstanding options on September 7, 1995 became
fully exercisable and vested as a result of the Merger.

    On October 22, 1996, the Board of Directors of Arch authorized the grant of
new options from the 1989 Plan to each employee who had an outstanding option at
a price greater than $12.50 (the fair market value of Arch's common stock on
October 23, 1996). The new option would be for the total number of shares (both
vested and unvested) subject to each employee's outstanding stock option
agreement(s). As a result of this action 531,846 options were terminated and
regranted at a price of $12.50. The Company treated this as a cancellation and
reissuance under APB opinion No. 25 "Accounting for Stock Issued to Employees".

    As a result of the Merger, Arch assumed a stock option plan originally
adopted by USA Mobile in 1994 and amended and restated on January 26, 1995 (the
"1994 Plan"), which provides for the grant of up to 601,500 options to purchase
Arch's common stock. Under the 1994 Plan, incentive stock options may be granted
to employees and nonqualified stock options may be granted to employees,
directors and consultants. Incentive stock options are granted at exercise
prices not less than the fair market value on the date of grant. Option duration
and vesting provisions are similar to the 1989 Plan. All outstanding options
under the 1994 Plan became fully exercisable and vested as a result of the
Merger.

    In January 1995, Arch adopted a 1995 Outside Directors' Stock Option Plan
(the "1995 Directors' Plan"), which terminated upon completion of the Merger.
Prior to termination of the 1995 Directors' Plan, 15,000 options were granted at
an exercise price of $18.50 per share. Options have a duration of ten years and
vest over a five-year period from the date of grant with the first such vesting
(20% of granted options) occurring one year from the date of grant and
continuing ratably at 5% on a quarterly basis thereafter.

    As a result of the Merger, Arch assumed from USA Mobile the Non-Employee
Directors' Stock Option Plan (the "Outside Directors Plan"), which provides for
the grant of up to 80,200 options to purchase Arch's common stock to
non-employee directors of Arch. Outside directors receive a grant of 3,000
options annually under the Outside Directors Plan, and newly elected or
appointed outside directors receive options to purchase 3,000 shares of common
stock as of the date of their initial election or appointment. Options are
granted at fair market value of Arch's common stock on the date of grant.
Options have a duration of ten years and vest over a three-year period from the
date of grant with the first such vesting (25% of granted options) occurring on
the date of grant and future vesting of 25% of granted options occurring on each
of the first three anniversaries of the date of grant.

    On February 10, 1997 the Board of Directors adopted, subject to stockholder
approval at the Company's annual meeting on May 20, 1997, the 1997 Stock Option
Plan under which 1,500,000 shares are available for future grants.

    Employee Stock Purchase Plan -- On May 28, 1996, the stockholders approved
the 1996 Employee Stock Purchase Plan (ESPP). The ESPP allows eligible employees
the right to purchase common stock on a semi-annual basis at the lower of 85% of
the market price at the beginning or the end of each six-month offering period.
During 1996, 46,842 shares were issued under the ESPP for a total consideration
of $373,000. At December 31, 1996, 203,158 shares are available for future
issuance.

    Accounting for Stock-Based Compensation -- Arch accounts for its stock
option and stock purchase plans under APB Opinion No. 25 "Accounting for Stock
Issued to Employees", since all options have been issued at a grant price equal
to fair market value, no compensation cost has been recognized in the Statement
of Operations. Had compensation cost for these plans been determined consistent
with SFAS No. 123 "Accounting for Stock-Based Compensation", Arch's net loss and
loss per share would have been increased to the following pro forma amounts:

</TABLE>

    Because the SFAS No. 123 method of accounting has not been applied to the
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 fair
value of each option grant is estimated on the date of grant using the
Black-Scholes option pricing model. In computing these pro forma amounts Arch
has assumed a risk-free interest rate of 6%, an expected life of 5 years, an
expected dividend yield of zero and an expected volatility of 50%.

    The weighted average fair values (computed consistent with SFAS No. 123) of
options granted under all plans in 1995 and 1996, were $11.89 and $4.95,
respectively. The weighted average fair value of shares sold under the ESPP in
1996 was $5.46.

    Stockholders Rights Plan -- Upon completion of the Merger, Arch's existing
stockholders rights plan was terminated. In October 1995, Arch's Board of
Directors adopted a new stockholders rights plan (the Rights) and declared a
dividend of one preferred stock purchase right (a Right) for each outstanding
share of common stock to stockholders of record at the close of business on
October 25, 1995. Each Right entitles the registered holder to purchase from
Arch one one-thousandth of a share of Series B Junior Participating Preferred
Stock, at a cash purchase price of $150, subject to adjustment. Pursuant to the
Plan, the Rights automatically attach to and trade together with each share of
common stock. The Rights will not be exercisable or transferable separately from
the shares of common stock to which they are attached until the occurrence of
certain events. The Rights will expire on October 25, 2005, unless earlier
redeemed or exchanged by Arch in accordance with the Plan.

    Public Offering -- In February 1995, Arch issued 2,701,296 shares of common
stock for net proceeds of approximately $46.2 million. Arch used its net
proceeds to repay borrowings of approximately $46.2 million outstanding under a
prior credit facility (see Note 3).

5.  INCOME TAXES

    Arch adopted the provisions of SFAS No. 109, "Accounting for Income Taxes",
in the year ended August 31, 1994. Such adoption had no effect on Arch's net
loss or financial position.

    The components of the net deferred tax asset (liability) recognized in the
accompanying consolidated balance sheets at December 31, 1995 and 1996 are as

    The effective income tax rate differs from the statutory Federal tax rate
primarily due to the nondeductibility of goodwill amortization. The net
operating loss (NOL) carryforwards expire at various dates through 2011. The
Internal Revenue Code contains provisions that may limit the NOL carryforwards
available to be used in any given year if certain events occur, including
significant changes in ownership, as defined.

6.  COMMITMENTS AND CONTINGENCIES

    Arch has operating leases for office and transmitting sites with lease terms
ranging from one month to approximately ten years. In most cases, Arch expects
that, in the normal course of business, leases will be renewed or replaced by
other leases.

    Future minimum lease payments under noncancellable operating leases at
December 31, 1996 are as follows (in thousands):

    Total rent expense under operating leases for the year ended August 31,
1994, the four months ended December 31, 1993 and 1994 and the years ended
December 31, 1995 and 1996 approximated $3,026,000, $883,000 (unaudited),
$1,202,000, $6,423,000 and $14,746,000, respectively.

7.  EMPLOYEE BENEFIT PLANS

    Arch has two retirement savings plans, including a plan assumed by Arch in
the Merger (see Note 2), qualifying under Section 401(k) of the Internal Revenue
Code covering eligible employees, as defined. Under the plans, a participant may
elect to defer receipt of a stated percentage of the compensation which would
otherwise be payable to the participant for any plan year (the deferred amount)
provided, however, that the deferred amount shall not exceed the maximum amount
permitted under Section 401(k) of the Internal Revenue Code. The plans provide
for Arch matching contributions. Matching contributions for the year ended
August 31, 1994, the four months ended December 31, 1993 and 1994 and the years
ended December 31, 1995 and 1996 approximated $74,000, $21,000 (unaudited),
$25,000, $124,000 and $217,000, respectively.

                         ARCH COMMUNICATIONS GROUP, INC.

                             1997 STOCK OPTION PLAN

     Adopted by the Board of Directors on February 10, 1997

1. Purpose

     The purpose of this 1997 Stock Option Plan (the "Plan") of Arch
Communications Group, Inc., a Delaware corporation (the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and incentives in order to better align the
interests of such persons with those of the Company's stockholders. Except where
the context otherwise requires, the term "Company" shall include any present or
future subsidiary corporations of Arch Communications Group, Inc. as defined in
Section 424(f) of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code").

2. Eligibility

     All of the Company's employees, officers, directors, consultants and
advisors are eligible to be granted options ("Options") under the Plan. Any
person who has been granted an Option under the Plan shall be deemed a
"Participant".

3. Administration, Delegation

     (a) Administration by Board of Directors. The Plan will be administered by
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Options and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable
from time to time to interpret and correct the provisions of the Plan and any
Option. No member of the Board shall be liable for any action or determination
relating to the Plan. All decisions by the Board shall be made in the sole
discretion of the Board and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Option.

     (b) Delegation to Executive Officers. To the extent permitted by applicable
law, the Board may delegate to one or more executive officers of the Company the
power to grant Options and exercise such other powers under the Plan as the
Board may determine, provided that the Board shall fix the maximum number of
shares subject to Options and the maximum number of shares for any one
Participant to be made by such executive officers.

<PAGE>   2

     (c) Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean a Committee or the Board or the executive officer
referred to in Section 3(b) to the extent of such delegation.

4. Stock Available for Options

     (a) Number of Shares. Subject to adjustment under Section 4(c), Options may
be granted under the Plan for up to 1,500,000 shares of common stock, $.01 par
value per share, of the Company (the "Common Stock"). If any Option expires or
is terminated, surrendered or canceled without having been fully exercised, the
unused Common Stock covered by such Option shall again be available for the
grant of Options under the Plan, subject, however, in the case of Incentive
Stock Options (as defined hereinafter) to any limitation required under the
Code. Shares issued under the Plan may consist in whole or in part of authorized
but unissued shares or treasury shares.

     (b) Per-Participant Limit. Subject to adjustment under Section 4(c), the
maximum number of shares with respect to which an Option may be granted to any
Participant under the Plan shall be 200,000 shares per calendar year. The
per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code.

     (c) Adjustment to Common Stock. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares, liquidation, spin-off or other similar change in
capitalization or event, or any distribution to holders of Common Stock other
than a normal cash dividend, (i) the number and class of securities available
under this Plan and (ii) the number and class of security and exercise price per
share subject to each outstanding Option shall be appropriately adjusted by the
Company (or substituted Options may be granted, if applicable) to the extent the
Board shall determine, in good faith, that such an adjustment (or substitution)
is necessary and appropriate. If this Section 4(c) applies and Section 6(e)(1)
also applies to any event, Section 6(e)(1) shall be applicable to such event,
and this Section 4(c) shall not be applicable to such event.

5. Stock Options

     (a) General. The Board may grant Options to purchase Common Stock and
determine the number of shares of Common Stock to be covered by each Option, the
exercise price of each Option and the conditions and limitations applicable to
the exercise of each Option, including conditions relating to applicable federal
or state securities laws, as it considers necessary or advisable. An


                                       -2-

<PAGE>   3

Option which is not intended to be an Incentive Stock Option (as hereinafter
defined) shall be designated a "Nonstatutory Stock Option".

     (b) Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c) Exercise Price. The Board shall establish the exercise price at the
time each Option is granted; provided, however, that in no event shall Options
be granted with an exercise price below the fair market value of the Common
Stock at the date of grant ("Fair Market Value") as determined by the Board in
good faith.

     (d) Duration of Options. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify.

     (e) Exercise of Option. Options may be exercised only by delivery to the
Company of a written notice of exercise signed by the proper person together
with payment in full as specified in Section 5(f) for the number of shares for
which the Option is exercised.

     (f) Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (i) in cash or by check, payable to the order of the Company;

          (ii) except as the Board may otherwise provide with respect to an
Option, delivery of an irrevocable and unconditional undertaking by a
creditworthy broker to deliver promptly to the Company sufficient funds (in cash
or by check) to pay the exercise price, or delivery by the Participant to the
Company of a copy of irrevocable and unconditional instructions to a
creditworthy broker to deliver promptly to the Company sufficient funds (in cash
or by check) to pay the exercise price;

          (iii) to the extent permitted by the Board and explicitly provided in
the agreement evidencing the Option (i) by delivery of shares of Common Stock
owned by the Participant valued at their fair market value as determined by the
Board in good faith ("Fair Market Value"), which Common Stock was owned by the
Participant at least six months prior to such delivery, (ii) by


                                       -3-

<PAGE>   4

delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (iii) by payment of such other lawful consideration
as the Board may determine; or

          (iv) any combination of the above permitted forms of payment.

6. General Provisions Applicable to Options

     (a) Transferability of Options. Except as the Board may otherwise determine
or provide with respect to an Option, Options shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant. References to Participant, to the extent
relevant in the context, shall include references to authorized transferees.

     (b) Documentation. Each Option under the Plan shall be evidenced by a
written instrument in such form as the Board shall determine. Each Option may
contain terms and conditions in addition to those set forth in the Plan.

     (c) Board Discretion. The terms of each Option need not be identical, and
the Board need not treat Participants uniformly.

     (d) Termination of Status. The Board shall determine the effect on an
Option of the disability, death, retirement, authorized leave of absence or
other change in the employment or other status of a Participant and the extent
to which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or the beneficiary designated by a
Participant in the event of the Participant's death (the "Designated
Beneficiary"). In the absence of an effective designation by a Participant,
Designated Beneficiary shall mean the Participant's estate.

     (e) Acquisition Events.

          (i) Consequences of Acquisition Events. Upon the occurrence of an
Acquisition Event (as defined below), or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall provide written
notice to the Participants that all Options then outstanding shall become
immediately exercisable in full as of a specified date (the "Acceleration Date")
prior to the Acquisition Event and will terminate immediately prior to the
consummation of such Acquisition Event, except to the extent exercised by the
Participants between the Acceleration Date and the consummation of such
Acquisition Event. An "Acquisition Event" shall mean: (a) any merger or
consolidation which results in the voting securities


                                       -4-

<PAGE>   5

of the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of
the surviving or acquiring entity) less than 50% of the combined voting power of
the voting securities of the Company or such surviving or acquiring entity
outstanding immediately after such merger or consolidation; (b) any sale of all
or substantially all of the assets of the Company; (c) the complete liquidation
of the Company; or (d) the acquisition of "beneficial ownership" (as defined in
Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) of securities of the Company representing 50% or more of the combined
voting power of the Company's then outstanding securities (other than through a
merger or consolidation or an acquisition of securities directly from the
Company) by any "person", as such term is used in Sections 13(d) and 14(d) of
the Exchange Act other than the Company, any trustee or other fiduciary holding
securities under an employee benefit plan of the Company, or any corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportion as their ownership of stock of the Company.

          (ii) Assumption of Options Upon Certain Events. The Board may grant
Options under the Plan in substitution for options and other stock-based awards
held by employees of another corporation who become employees of the Company as
a result of a merger or consolidation of the employing corporation with the
Company or the acquisition by the Company of property or stock of the employing
corporation. The substitute Options shall be granted on such terms and
conditions as the Board considers appropriate in the circumstances.

     (f) Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Company for payment of, any taxes required by law
to be withheld in connection with such Participant's Option no later than the
date of the event creating the tax liability. The Board may allow Participants
to satisfy such tax obligations in whole or in part in shares of Common Stock,
including shares retained from the Option creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

     (g) Amendment of Option. The Board may amend, modify or terminate any
outstanding Option, including but not limited to substituting therefor another
Option, changing the date of exercise or converting an Incentive Stock Option to
a Nonstatutory Stock Option, provided that the Participant's consent to such
action shall be required unless the Board determines that the action, taking
into account any related action, would not materially and adversely affect the
Participant.

                                       -5-

<PAGE>   6

     (h) Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan until (i) all conditions
of the Option have been met or removed to the satisfaction of the Company, (ii)
in the opinion of the Company's counsel, all other legal matters in connection
with the issuance and delivery of such shares have been satisfied, including any
applicable securities laws and any applicable stock exchange or stock market
rules and regulations, and (iii) the Participant has executed and delivered to
the Company such representations or agreements as the Company may consider
appropriate to satisfy the requirements of any applicable laws, rules or
regulations.

7. Miscellaneous

     (a) No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Option, and the grant of an Option shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Option agreement.

     (b) No Rights As Stockholder. Subject to the provisions of the applicable
Option agreement, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock issuable upon
exercise of an Option until becoming the record holder thereof.

     (c) Effective Date and Term of Plan. The Plan shall become effective on the
date on which it is adopted by the Board, but no Option granted to a Participant
designated as subject to Section 162(m) by the Board shall become exercisable
unless and until the Plan has been approved by the Company's stockholders. No
Options shall be granted under the Plan after the completion of ten years from
the earlier of (i) the date on which the Plan was adopted by the Board or (ii)
the date the Plan was approved by the Company's stockholders, but Options
previously granted may extend beyond that date.

     (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time, provided that no Option granted to a
Participant designated as subject to Section 162(m) by the Board after the date
of such amendment shall become exercisable, to the extent that such amendment to
the Plan was required to grant such Option to a particular Participant, unless
and until such amendment shall have been approved by the Company's stockholders.



                                       -6-

     (e) Stockholder Approval. For purposes of this Plan, stockholder approval
shall mean approval by a vote of the stockholders in accordance with the
requirements of Section 162(m) of the Code.

     (f) Governing Law. The provisions of the Plan and all Options granted
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.
