                               PROSPECTUS SUMMARY

                                    TeleCorp

   We are the largest AT&T Wireless affiliate in the United States, with
licenses covering approximately 16.5 million people. We provide wireless
personal communications services in selected markets in the south-central and
northeast United States and in Puerto Rico, encompassing eight of the 100
largest metropolitan areas in the United States. Commencing with the launch of
our New Orleans market in February 1999, we have successfully launched our
services in 21 markets, including all of our major markets, and currently have
more than 100,000 subscribers. Our senior management team has substantial
experience in the wireless communications industry with companies such as AT&T,
Bell Atlantic and Sprint PCS.

                          Strategic Alliance with AT&T

   We entered into a venture with AT&T in July 1998 under which AT&T
contributed personal communications services, or PCS, licenses to us in
exchange for ownership in our company. AT&T is one of our largest investors,
beneficially owning approximately 18% of our class A common stock upon
completion of this offering and the concurrent offering to AT&T Wireless. As an
AT&T Wireless affiliate, we enjoy numerous strategic benefits, including the
following:

  .  Exclusivity. We are AT&T's exclusive provider of wireless mobility
     services using equal emphasis co-branding with AT&T in our covered
     markets, subject to AT&T's right to resell services on our network.

  .  Brand. We have the right to use the AT&T brand name and logo together
     with our SunCom brand name and logo in our covered markets, giving equal
     emphasis to each. We also benefit from AT&T's nationwide advertising and
     marketing campaigns.

  .  Roaming. We are AT&T's preferred roaming partner in our markets. Our
     roaming revenues increased from approximately $1.9 million in the first
     quarter of 1999 to approximately $9.5 million in the third quarter. We
     believe our AT&T Wireless affiliation will continue to provide us with a
     valuable base of recurring roaming revenue.

  .  Coast-to-Coast Coverage. Outside our markets, our wireless customers can
     place and receive calls in AT&T Wireless markets and the markets of AT&T
     Wireless' other roaming partners. Our ability to offer coast-to-coast
     coverage is a competitive advantage as users increasingly choose
     national rate plans. As of September 30, 1999, 19% of our customers have
     chosen one of our national SunRate(TM) pricing plans.

                                    Markets

   Our PCS licenses include several major population centers and popular
vacation destinations such as:

  .  San Juan, Puerto Rico and the U.S. Virgin Islands;

  .  New Orleans and Baton Rouge, Louisiana;

  .  Memphis, Tennessee;

  .  Little Rock, Arkansas;

  .  Manchester, Concord and Nashua, New Hampshire; and

  .  Worcester, Cape Cod, Martha's Vineyard and Nantucket, Massachusetts.

   Our launched networks covered approximately 65% of our licensed population
as of September 30, 1999, and by the end of 1999 we expect our network will
cover approximately 75% of our licensed population.

                             Competitive Strengths

   Our goal is to provide our customers with simple-to-buy, easy-to-use
wireless services, including coverage across the nation, superior call quality,
competitive pricing and personalized customer care. In addition to our
strategic alliance with AT&T, we believe we have several key business,
operational and marketing advantages, including our:

  .  Attractive Markets. Our markets have favorable demographic
     characteristics for personal communications services with an average
     population density of approximately 30% above the national average. We
     believe our markets are strategically important to AT&T because they are
     located near or adjacent to traffic corridors in and around large
     markets such as Boston, Houston and St. Louis. Our markets include major
     population and business centers and vacation destinations that attract
     an estimated 39 million visitors per year. Most of our markets are also
     adjacent to the markets of the other SunCom companies, Triton PCS, Inc.
     and Tritel Communications, Inc.

  .  Experienced and Incentivized Management. Our 21 member senior management
     team has an average of 11 years of experience in the wireless industry.
     Together, they will beneficially own approximately 11% of our class A
     common stock on a fully-diluted basis upon completion of this offering
     and the concurrent AT&T Wireless offering.

  .  Substantial Airwave Capacity. We have licenses with a minimum of 35 MHz
     of airwaves in our major urban markets of San Juan and New Orleans and
     30 MHz in Little Rock and Memphis. Megahertz, or MHz, represents a
     measure of airwave capacity. These amounts are equal to or greater than
     those held by each of our principal competitors in each of these
     markets. We believe these amounts of airwaves will enable us to
     competitively deploy new and enhanced voice and data services. This
     capacity will also permit us to provide service to the increasing number
     of wireless users and to service increased use by subscribers.

  .  Strong Capital Base. Upon completion of this offering and the concurrent
     offering, we will have approximately $1.6 billion of funded and
     committed capital. We believe our existing capital resources, including
     the proceeds of this offering and the concurrent offering, will be
     sufficient to fund our current business plan, including capital
     expenditures and operating losses, through the end of 2001.

  .  Advanced Digital Technology. We are building our network using time
     division multiple access technology, which makes our network compatible
     with AT&T's network and other time division multiple access networks.
     This technology allows us to offer enhanced features and services
     relative to standard cellular service, including extended battery life,
     integrated voicemail, paging, fax and e-mail delivery, enhanced voice
     privacy and short-messaging capability.

                                  Risk Factors

   You should consider carefully all of the information described in this
prospectus and, in particular, you should evaluate the specific factors under
"Risk Factors" beginning on page 6.

  .  has been restated to give effect to a 100-for-1 stock split of our
     common stock and series F preferred stock effected on August 27, 1999
     and a 3.09-for-1 stock split of our common stock and series F preferred
     stock effected on November 8, 1999, and

  .  assumes no exercise of the underwriters' over-allotment option or the
     issuance of up to 295,000 shares issuable to AT&T Wireless if the
     underwriter's over-allotment is exercised.

(a) Pro forma basic and diluted net loss attributable to common equity per
    share have been calculated assuming that our pending acquisitions of the
    remaining minority interest of Viper Wireless, Inc. that we do not
    currently own and of TeleCorp LMDS, Inc. and the completed acquisitions of
    Digital PCS, LLC, AT&T Puerto Rico and Wireless 2000, Inc. had been
    completed at the beginning of the periods presented. Since we had a net
    loss attributable to common equity in each of the periods presented, pro
    forma basic and diluted net loss attributable to common equity per share is
    the same.

    AT&T Wireless, our pending acquisitions and adjustments relating to
    completed acquisitions. See "Management's Discussion and Analysis of

                                  RISK FACTORS

   Investing in shares of our class A common stock involves a high degree of
risk. You should carefully consider the risks described below as well as all
the other information in this prospectus--including our financial statements
and related notes--before investing in our class A common stock. Our business,
operating results and financial condition could be seriously harmed due to any
of the following risks. The trading price of our class A common stock could
decline due to any of these risks, and you could lose all or part of your
investment.

We may never achieve operating profitability or generate sufficient cash flow
to meet our obligations.

   Our operating history is limited, and we have a history of operating losses.
If we do not achieve and maintain positive cash flow from operations on a
timely basis, we may be unable to develop our network or conduct our business
in an effective or competitive manner. As of September 30, 1999, we had
incurred cumulative net losses of approximately $199.1 million. We expect to
continue to incur operating losses and to generate negative cash flow from
operating activities during the next several years while we develop our
business and expand our network. Additionally, our business has required and
will continue to require substantial capital expenditures. We will have to
dedicate a substantial portion of any cash flow from operations to make
interest and principal payments on our debt, which will reduce funds available
for other purposes.

   As a result of the initial public offering, the value of some outstanding
stock option and restricted stock awards will become fixed and a portion of
them will be fully vested. Some other awards will become fixed upon FCC
approval of the pending Viper Wireless transaction. Based on the initial public
offering price of $20.00 per share, we expect to record approximately $29.7
million of additional compensation expense in the fourth quarter of 1999 in
connection with these awards. We expect to recognize an additional $54.3
million over time as the remaining awards vest. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

We depend on our agreements with AT&T for our success, and we would have
difficulty operating without them. In addition, our roaming rates with AT&T
will decline over time.

   We have entered into a number of agreements with AT&T, including:

  .  a license agreement;

  .  a stockholders' agreement;

  .  an intercarrier roamer services agreement;

  .  a roaming administration service agreement; and

  .  a long distance agreement.

   In limited situations, AT&T may withdraw from these agreements with us. If
any of the agreements we have entered into with AT&T are not renewed or are
terminated, we would have difficulty operating.

   In addition, under the roaming agreement, the roaming rate that AT&T pays to
us when AT&T's customers roam onto our network will decline over each of the
next several years and may be renegotiated. This may affect our roaming
revenue, most of which has historically been derived from AT&T Wireless'
customers traveling through our markets.

   We have agreements with AT&T for equipment discounts. Any disruption in our
relationship with AT&T could hinder our ability to obtain the infrastructure
equipment that we use in our network or harm our relationship with our vendors.

Our agreements with AT&T contain stringent development requirements which, if
not met, will result in the loss of some of our rights under those agreements.

   The agreements we have entered into with AT&T contain requirements regarding
the construction of our network, which, in many instances, are more stringent
than those imposed by the FCC. The construction of the

                                       6
<PAGE>

remainder of our network involves risks of unanticipated costs and delays. If
we fail to meet AT&T's requirements, AT&T could terminate the exclusivity of
our relationship. Other providers could then enter into agreements with AT&T
and we could lose access to customers. See "Business--Network Development" and
"Certain Relationships and Related Transactions--AT&T Agreements."

AT&T could terminate its exclusive relationship with us.

   If AT&T combines with specified entities with over $5 billion in revenue
from communications activities that have overlapping PCS or cellular licenses
with us, then AT&T may terminate its exclusivity obligations with us in markets
that overlap with markets of those entities. Other providers could then enter
into agreements with AT&T in those markets, exposing us to increased
competition, and we could lose access to customers.

   In addition, AT&T can at any time require us to enter into a resale
agreement which would allow AT&T to sell access to, and usage of, our services
in our licensed area on a nonexclusive basis using the AT&T brand. See "Certain
Relationships and Related Transactions--AT&T Agreements."

We rely on the use of the AT&T brand name and logo to market our services, and
a loss of use of this brand and logo or a decrease in the market value of this
brand and logo would hinder our ability to market our products.

   The AT&T brand and logo is highly recognizable and AT&T supports its brand
and logo by its marketing. If we lose our rights to use the AT&T brand and logo
under our license agreement, we would lose the advantages associated with
AT&T's marketing efforts. If we lose the rights to use this brand and logo,
customers may not recognize our brand readily and we may have to spend
significantly more money on advertising to create brand recognition. See
"Business--Marketing Strategy," "--Intellectual Property" and "Certain
Relationships and Related Transactions--AT&T Agreements."

   In addition, we depend on AT&T's success as a wireless communications
provider and the value of its brand and logo because many of our operations use
AT&T's network. If AT&T encounters problems in developing and operating its
wireless network it could adversely affect the value to us of the AT&T brand
and our agreements with AT&T. In that event, we may need to invest heavily in
obtaining other operating agreements and in marketing our brand to develop our
business, and we may not have funds to do so.

If we fail to maintain certain quality standards, AT&T could terminate its
exclusive relationship with us and our rights to the AT&T brand.

   If we fail to meet specified customer care, reception quality and network
reliability standards set forth under the stockholders' agreement, AT&T may
terminate its exclusivity obligations with us and our rights to use the AT&T
brand. If AT&T terminates its exclusivity obligations, other providers could
then enter into agreements with AT&T, exposing us to increased competition, and
we could lose access to customers. If we lose our rights to use the AT&T brand,
we would lose the advantages associated with AT&T's marketing efforts. If we
lose the rights to use this brand, customers may not recognize our brand
readily. We may have to spend significantly more money on advertising to create
a brand recognition. See "Certain Relationships and Related Transactions--AT&T
Agreements."

Our association with the other SunCom companies may harm our reputation if
consumers react unfavorably to them.

   We use the SunCom brand name to market our products and services in
conjunction with two other affiliates of AT&T Wireless, Triton PCS and Tritel
Communications, in order to broaden our marketing exposure and share the costs
of advertising. If either of those companies encounters problems in developing
and operating its network, it could harm consumer perception of the SunCom
brand, and in turn harm our own reputation.

                                       7

We may not be able to manage the construction of our network or the growth of
our business successfully.

   We have experienced rapid growth and development in a relatively short
period of time and expect to continue to experience rapid growth in the future.
Our financial performance will depend on our ability to manage such growth and
the successful construction of our network. Our management may not be able to
direct our development effectively, including implementing adequate systems and
controls in a timely manner or retaining qualified employees. This inability
could slow our growth and our ability to compete in the wireless communications
service industry.

We have substantial existing debt, and may incur substantial additional debt,
that we may be unable to service.

   We have a substantial amount of debt and may incur substantial additional
debt in the future, and we may not have sufficient funds to make interest and
principal payments on our debt. As of September 30, 1999, our outstanding debt
was approximately $629.8 million. Our senior credit facilities provide for
total borrowings in the amount of up to $560.0 million. In addition, Lucent has
committed to purchase up to an additional $75.0 million of junior subordinated
notes in connection with our development of new markets.

   We expect to incur substantial additional debt under existing commitments in
connection with the construction of our network and operation of our existing
markets. In addition, if we acquire licenses in additional markets we would
expect to incur substantial additional debt as part of the financing of the
acquisition and the construction and operation of PCS systems in those markets.
We may not have sufficient cash flow in the future to service any additional
debt we incur.

Our substantial amount of debt makes us especially susceptible to competition
and market fluctuations, which may affect our ability to grow our business or
service our debt.

   Our substantial amount of debt limits our ability to adjust to changing
market conditions. Because we require significant amounts of cash flow to
service our debt, we may not be able to discount our prices to maintain
competitive pricing packages. If our business does not grow, we may not have
funds to service our debt. We need to realize a significant amount of revenue
to pay our debt.

Our debt instruments contain restrictive covenants that may limit our operating
flexibility.

   The documents governing our indebtedness, including the credit facility and
senior subordinated note indenture, contain significant covenants that limit
our ability to engage in various transactions and, in the case of the credit
facility, require satisfaction of specified financial performance criteria. In
addition, under each of these documents, the occurrence of specific events, in
some cases after notice and grace periods, would constitute an event of default
permitting acceleration of the respective indebtedness. The limitations imposed
by the documents governing our outstanding indebtedness are substantial, and if
we fail to comply with them, our debts could become immediately payable at a
time when we are unable to pay them.

If we do not pay our debt owed to the U.S. government when due, the FCC may
impose financial penalties on us or terminate or modify our licenses.

   If we do not pay the interest and principal on any debt that we or our
subsidiaries owe to the U.S. government when it is due, the FCC may:

  .  impose substantial financial penalties;

  .  reclaim and reauction the licenses for which we incurred the debt;

  .  not renew any of our other licenses; and

  .  pursue other enforcement measures.

   Any of these FCC actions would slow our growth and our ability to compete in
the wireless communications industry. See "Description of Indebtedness--
Government Debt."

Some of our stockholders are obligated to make equity contributions to us in
the future and we cannot guarantee that they will make those contributions.

   We received unconditional and irrevocable equity commitments from some of
our stockholders in connection with the completion of our venture with AT&T and
certain other acquisitions. In return for these commitments, these stockholders
received shares of our common and preferred stock, which they pledged to us and
our senior bank lenders to secure their commitments. These stockholders are
required to fund $37.7 million of these commitments in 2000, $48.6 million in
2001 and the remaining $11.0 in 2002. Under certain circumstances, these
stockholders can transfer their interests in our preferred stock, subject to
the pledge, prior to funding their commitments. In the event any of these
stockholders do not fund the remaining portions of their commitments, we could
foreclose on their pledged shares, but we would likely have to obtain
alternative financing to complete our network. Such financing may not be
available on terms satisfactory to us. If we are unable to secure alternate
financing, we may have to delay, modify or abandon some of our plans to
construct the remainder of our network.

We may not be able to obtain the additional financing we may need to complete
our network and fund operating losses.

   We will make significant capital expenditures to finish the construction,
testing and deployment of our network. The actual expenditures necessary to
achieve these goals may differ significantly from our estimates. We cannot
predict whether any additional financing we may need will be available, or what
the terms of any such additional financing would be or whether our existing
debt agreements will allow additional financing. We may incur variable rate
debt, which would make us more vulnerable to interest rate increases. If we
cannot obtain additional financing when needed, we will have to delay, modify
or abandon some of our plans to construct the remainder of our network, which
could slow our growth and our ability to compete in the wireless communications
industry.

   We would have to obtain additional financing if, among other things:

  .  any of our sources of capital are unavailable or insufficient;

  .  we significantly depart from our business plan;

  .  we experience unexpected delays or cost overruns in the construction of
     our network;

  .  we experience increases in operating costs;

  .  changes in technology or governmental regulations create unanticipated
     costs; or

  .  we acquire additional licenses.

We have many competitors that have substantial coverage of our licensed areas,
which makes it difficult for us to acquire and maintain a strong competitive
position and to earn profits.

   We compete in our markets with three or more major U.S. wireless
communications services companies in each of our markets, such as:

  .  Bell Atlantic;

  .  BellSouth;

  .  GTE;

  .  SBC Communications; and

  .  Sprint PCS.

   In some markets, we compete with as many as five major competitors. Many of
these competitors have greater financial, marketing and sales and distribution
resources than we do. In addition, some of these

                                       9
<PAGE>

competitors have achieved substantial coverage in portions of our licensed
areas. Some of our competitors have more extensive coverage within our licensed
areas than we provide and also have broader regional coverage. In order to
attract customers and otherwise compete effectively, we may have to
significantly discount our prices, which may reduce our revenues and make it
more difficult for us to achieve positive cash flow to meet our obligations.
See "Business--Competition."

We may not be able to effectively compete with carriers who entered the
wireless communications market before us.

   Competitors who entered the wireless communications services market before
us may have a significant time-to-market advantage over us. As a new entrant in
the market, we may have to significantly discount our prices to attract
customers, which would make it more difficult for us to achieve positive cash
flow to meet our obligations. See "Business--Competition."

Some competitors may have different or better technology than us, and may
attract more customers.

   We compete with companies that use other communications technologies,
including paging and digital two-way paging, enhanced specialized mobile radio
and domestic and global mobile satellite service. Specialized mobile radio is a
digital technology system that reuses radio airwaves. These technologies may
have advantages over our technology, and may attract our customers. See
"Business--The Wireless Communications Industry."

Competitors who offer more services than us may attract more customers.

   Some of our competitors market other services, such as traditional telephone
service, cable television access and access to the Internet, together with
their wireless communications services, which may make their services more
attractive to customers. They may attract customers away from us, or prevent us
from attracting customers. In addition, in the future, we expect that providers
of traditional telephone services, energy companies, utility companies and
cable operators who expand their services to offer communications services may
compete with us and other wireless providers. See "Business--Competition."

We may not be able to acquire the sites necessary to complete our network.

   We must lease or otherwise acquire rights to use sites for the location of
network equipment and obtain zoning variances and other governmental approvals
for construction of our network and to provide wireless communications services
to customers in our licensed areas. If we encounter significant difficulties in
leasing or otherwise acquiring rights to sites for the location of network
equipment, we may need to alter the design of our network. Changes in our
development plan could slow the construction of our network, which would make
it harder to compete in the wireless communications industry or cause us not to
meet development requirements.

Difficulties in obtaining infrastructure equipment may affect our ability to
construct our network and meet our development requirements.

   If we do not receive our network equipment in a timely manner, we may be
unable to provide wireless communications services comparable to those of our
competitors. We have purchased a substantial majority of our network equipment
from Lucent. There is high demand for the equipment that we require to
construct our network, and manufacturers of this equipment, including Lucent,
could have substantial backlogs of orders. Accordingly, the lead time for the
delivery of this equipment may be long. Some of our competitors purchase large
quantities of communications equipment and may have established relationships
with the manufacturers of this equipment, such as Lucent. Consequently, they
may receive priority in the delivery of this equipment. If we fail to construct
our network in a timely manner, we may not be able to compete effectively, we
could lose our licenses or we could breach our agreements with AT&T. See
"Business--Network Development" and "Certain Relationships and Related
Transactions--AT&T Agreements."

                                       10

Potential acquisitions may require us to incur substantial additional debt and
integrate new technologies, operations and services, which may be costly and
time consuming.

   We continually evaluate opportunities for the acquisition of licenses and
properties that will compliment or extend our existing operations. If we
acquire new licenses or facilities, we may encounter difficulties that may be
costly and time-consuming and that may slow our growth, which could lower the
market value of our class A common stock. Examples of such difficulties are
that we may have to:

  .  incur substantial additional debt to finance the acquisitions;

  .  assume U.S. government debt related to any licenses we acquire;

  .  integrate new technologies with our technology;

  .  integrate new operations with our operations;

  .  integrate new services with our offering of services; or

  .  divert the attention of our management from other business concerns.

We may experience a high rate of customer turnover which may negatively impact
our business.

   Many providers in the personal communications services industry have
experienced a high rate of customer turnover as compared to cellular industry
averages. Our strategy to address customer turnover may not be successful, or
the rate of customer turnover may be unacceptable. The rate of customer
turnover may be the result of several factors, including network coverage,
reliability issues such as blocked and dropped calls, handset problems,
nonusage of phones, change of employment, affordability, customer care concerns
and other competitive factors. Price competition and other competitive factors
could also cause increased customer turnover.

We depend upon consultants and contractors for our network services, and if any
of them fail to perform its obligations to us, we may not complete our network
development on a timely basis.

   We have retained Lucent and other consultants and contractors to help us to
design, construct and support our network. See "Business--Network Development."
The failure by any of these consultants or contractors to fulfill its
contractual obligations could slow the construction of our network in a timely
manner, which could slow our growth and our ability to compete in the wireless
communications industry.

We may become subject to new health and safety regulations, which may result in
a decrease in demand for our services.

   Media reports have suggested that some radio airwave emissions from wireless
handsets may be linked to health concerns. These reports could discourage the
use of wireless handsets, which would decrease demand for our services. Recent
studies have also suggested that hand-held phones may interfere with medical
devices. Subsequent studies that raise public concern could decrease demand for
our services. Governmental authorities may create new regulations concerning
hand-held phones, and our handsets may not comply with rules adopted in the
future. Noncompliance would decrease demand for our services. In addition, some
state and local legislatures have passed or are considering restrictions on
wireless phone use for drivers. The passage or proliferation of this or future
legislation could decrease demand for our services. See "Business--Government
Regulation."

If the management agreement with TeleCorp Management is terminated, we may not
be able to comply with applicable FCC rules.

   Under our management agreement with TeleCorp Management, Mr. Vento and Mr.
Sullivan provide management services to us regarding the design, development
and operation of our network. If the management agreement is terminated, we may
have limited success and less ability to comply with the FCC rules regarding
our licenses. See "Business--Government Regulation" and "Management--Management
Agreement."

                                       11
<PAGE>

If we cannot retain senior management, we may not be able to effectively run
our business.

   We depend on Mr. Vento, our Chief Executive Officer, Mr. Sullivan, our
Executive Vice President and Chief Financial Officer, and Ms. Dobson, our Chief
Operating Officer, for management leadership. If we lose the services of any of
these executives, we may not be successful in running our business. We do not
carry life insurance on Mr. Vento, Mr. Sullivan or Ms. Dobson. See
"Management."

Government regulation, changes in our licenses or other governmental action
could affect how we do business.

   Congress, the FCC, the Federal Aviation Administration, state and local
regulatory authorities or the courts may adopt new regulations, amend existing
regulations, alter the administration of existing regulations or take other
actions that might cause us to incur significant costs in making changes to our
network, and such costs might affect our cash flows.

   As the FCC continues to implement changes to promote competition under the
Communication Act of 1934, as amended by the Telecommunication Act of 1996, it
may change how it regulates how our network connects with other carriers'
networks. The FCC may require us to provide lower cost services to other
carriers, which may lessen our revenues.

   Our licenses to provide wireless communications services, which are our
principal assets, have terms of ten years. The FCC may revoke all of our
licenses at any time for cause, which includes our failure to comply with the
terms of the licenses, our failure to remain qualified under applicable FCC
rules to hold the licenses, violations of FCC regulations and malfeasance and
other misconduct. The FCC may not renew our licenses upon expiration of their
terms. Further, the FCC could modify our licenses in a way that decreases their
value or use to us or allocate unused airwaves for similar services. The
nonrenewal or loss of any of our licenses would slow our growth and our ability
to compete in the wireless communications industry. See "Business--Government
Regulation."

We could lose our PCS licenses or incur financial penalties if the FCC
determines we are not a very small business or if we do not meet the FCC's
minimum construction requirements.

   The FCC could impose penalties on us related to our very small business
status and its requirements regarding minimum construction of our network that
could slow our growth and our ability to compete in the wireless communications
industry.

   We and TeleCorp Holding acquired PCS licenses as a very small business, and
TeleCorp Holding and we must remain a very small business for at least five
years to comply with applicable rules of the FCC, including rules governing our
capital and ownership structure and corporate governance. If the FCC determines
that we violated these rules or failed to meet its minimum construction
requirements, it could impose substantial penalties upon us or TeleCorp
Holding. Among other things, the FCC could:

  .  fine us;

  .  revoke our licenses;

  .  accelerate our installment payment obligations; or

  .  cause us to lose bidding credits retroactively.

See "Business--Government Regulation."

The technologies that we use may become obsolete, which would limit our ability
to compete effectively.

   If our technologies become obsolete, we may need to purchase and install
equipment necessary to allow us to convert to new technologies to compete in
the marketplace. We use the TDMA, or time division multiple access, technology
standard in our network. This digital technology allocates a discrete amount of

technologies, such as CDMA, or code division multiple access, and GSM, or
global system for mobile communications, may have significant advantages over
TDMA. CDMA codes and sends scrambled speech using very few information bits on
a network. GSM encompasses uniform standards in Europe and Japan. Our
agreements with AT&T include conditions requiring us to upgrade of our
technology to match the technology of AT&T. We may not be able to purchase and
install successfully the equipment necessary to allow us to convert to a new or
different technology or to adopt a new or different technology at an acceptable
cost, if at all. In addition, the technologies that we choose to invest in may
not lead to successful implementation of our business plan. See "Business--The
Wireless Communications Industry" and "Certain Relationships and Related
Transactions--AT&T Agreements."

We expect to incur operating costs due to fraud.

   Based upon the experiences of other providers of wireless communications
services, we expect to incur costs as a result of the unauthorized use of our
network and to lose revenues. If we are not able to control the unauthorized
use of our network, or if we experience unanticipated types of fraud, we will
not collect revenues owing to us and will incur costs. These costs include the
capital and administrative costs associated with detecting, monitoring and
reducing the incidence of fraud and the costs associated with payments to other
providers of wireless communications services for unbillable fraudulent roaming
on their networks.

A limited number of stockholders control us, and their interests may be
different from yours.

   Mr. Vento and Mr. Sullivan will continue to control at least 50.1% of our
total voting power after the offering through their ownership of the voting
preference stock and have agreed to vote their shares of this stock together on
all matters. In addition, Chase Capital Partners, Equity Linked Investors-II,
Hoak Communications Partners, L.P., Whitney Equity Partners, LP, Media
Communications Partners, AT&T Wireless and TWR Cellular, Inc., will control
approximately 37.0% of our total voting power, in the aggregate, after this
offering and the concurrent offering to AT&T Wireless. Mr. Vento and Mr.
Sullivan together, and collectively with these stockholders, will have the
power to elect all of our directors. They have agreed in a stockholders
agreement to arrangements for the designation of board nominees and to vote
their shares together to elect all of the nominees designated by them under the
stockholders agreement. As a result of their stock ownership, these
stockholders and our management will have the ability to control our future
operations and strategy. They will also be able to effect or prevent a sale or
merger or other change of control of us. In addition, by virtue of their
ownership of voting preference stock, Mr. Vento and Mr. Sullivan can control
the outcome of any matter that requires a vote of a majority of the common
stock and can prevent the approval of any matter that requires a supermajority
vote of the common stock.

   Conflicts of interest between these stockholders and management stockholders
and our public stockholders may arise with respect to sales of shares of class
A common stock owned by our initial investors and management stockholders or
other matters. For example, sales of shares by our initial investors and
management stockholders could result in a change of control under our credit
facility, which would constitute an event of default under the credit facility,
and under our senior subordinated discount note indenture, which would require
us to offer to repurchase those notes. In addition, the interests of our
initial investors and other existing stockholders regarding any proposed merger
or sale may differ from the interests of our new public stockholders,
especially if the consideration to be paid for the class A common stock is less
than the price paid by public stockholders in this offering.

Our initial investors, directors and members of our management have interests
in other personal communications services companies, and conflicts of interest
may arise from these investments and from other directorships held by our
directors.

   Our initial investors, or their affiliates, currently have significant
investments in personal communications services companies other than us. These
initial investors may in the future invest in other entities that compete with
us. In addition, several of our directors, including Mr. Vento and Mr.
Sullivan, serve as directors of, own, or may acquire interests in other
communications services companies. As a result, these directors may be

                                       13
<PAGE>

subject to conflicts of interest during their tenure as our directors. Also,
Mr. Vento or Mr. Sullivan may allocate a portion of their time to managing
these companies. Our interests may conflict with the interests of these
companies and any conflicts may not be resolved in our favor.

   In addition, Mr. Vento and Mr. Sullivan own several companies that have
acquired PCS licenses in markets where we do not currently operate. AT&T has
provided financing for these companies. Mr. Vento and Mr. Sullivan may allocate
a portion of their time to managing these companies. These relationships may
result in conflicts of interest between us and Mr. Vento and Mr. Sullivan and
these conflicts may not be resolved in our favor.

We do not intend to pay dividends in the foreseeable future.

   We have never declared or paid any cash dividends on our common stock. For
the foreseeable future, we intend to retain any earnings to finance the
development and expansion of our business, and we do not anticipate paying any
cash dividends on our common stock. Payment of any future dividends on our
common stock will depend on our earnings and capital requirements, the terms of
our debt instruments and preferred stock and other factors our board of
directors considers appropriate.

Our stock price is likely to be very volatile.

   Prior to this offering, you could not buy or sell our class A common stock
publicly. The market price of the class A common stock after this offering may
vary from the initial public offering price. The market price of our class A
common stock is likely to be highly volatile and could be subject to wide
fluctuations in response to factors such as the following, some of which are
beyond our control:

  .  quarterly variations in our operating results;

  .  operating results that vary from the expectations of securities analysts
     and investors;

  .  changes in expectations as to our future financial performance,
     including financial estimates by securities analysts and investors;

  .  changes in the status of our intellectual property and other proprietary
     rights;

  .  changes in law and regulation;

  .  announcements by third parties of significant claims or proceedings
     against us;

  .  changes in market valuations of other PCS companies;

  .  announcements of technological innovations or new services by us or our
     competitors;

  .  announcements by us or our competitors of significant contracts,
     acquisitions, strategic partnerships, joint ventures or capital
     commitments;

  .  additions or departures of key personnel;

  .  future sales of our class A common stock; and

  .  stock market price and volume fluctuations.

Additional shares of our class A common stock will be eligible for public sale
in the future and could cause our stock price to drop, even if our business is
doing well.

   After this offering and the concurrent offering to AT&T Wireless, we will
have 85,023,889 shares of class A common stock outstanding, or 86,698,889
shares if the underwriters' over-allotment option is exercised in full, and we
have reserved an additional 1,814,321 shares of class A common stock for the
issuance of stock options available for grant under our 1999 Stock Option Plan,
552,505 of which have been granted as of September 30, 1999, and 118,390 shares
are available for grant under our 1998 Restricted Stock Plan. In addition, we
anticipate issuing 1,337,322 shares of class A common stock in connection with
pending acquisitions, an aggregate of 16,051,110 shares of our class A common
stock may be issued upon conversion of our class C and class D and voting
preference common stock and our series F preferred stock, and, based on

                                       14
<PAGE>

the September 30, 1999 liquidation preference of the series A preferred stock
and the initial public offering price of $20.00 per share, 5,350,000 shares of
class A common stock would be issuable upon conversion of our outstanding
series A preferred stock. The shares sold in this offering, except for any
shares purchased by our affiliates, may be resold in the public market
immediately. The shares sold to AT&T Wireless in the concurrent offering and
the shares sold to some of our other stockholders in this offering will be
subject to the stockholders' agreement described in the table below. The
remaining shares of our outstanding class A common stock, representing
approximately 90.8% of the total class A common stock outstanding, will be
restricted securities and will become available for resale in the public market
as shown in the chart below.

   We also intend to register under the Securities Act of 1933 1,814,321 shares
of our class A common stock reserved for issuance under our 1999 Stock Option
Plan.

   As restrictions on resale end, the market price could drop significantly if
the holders of these restricted shares sell them or are perceived by the market
as intending to sell them. See "Shares Eligible for Future Sale."

We depend on our third party service providers to become year-2000 compliant
and we can not assure that this will occur.

   We are dependent upon the ability of our third party service providers to
make their software and equipment year-2000 compliant. The failure of such
third party service providers to be year-2000 compliant may affect, among other
things, our clearing house services and billing systems and our customers'
ability to receive local access and over the air activation or to roam on other
networks.

   We have engaged a nationwide provider of year-2000 services and initiated a
year-2000 readiness program. While we expect our systems will be year-2000
compliant, we can not guarantee that this will be the case.

Anti-takeover provisions affecting us could prevent or delay a change of
control that you may favor.

   Provisions of our restated certificate of incorporation that will become
effective upon closing of this offering and our bylaws, provisions of our debt
instruments and other agreements, and provisions of applicable Delaware law and
applicable federal and state regulations may discourage, delay or prevent a
merger or other change of control that stockholders may consider favorable. The
provisions of our restated certificate of incorporation or bylaws, among other
things, will:

  .  divide our board of directors into three classes, with members of each
     class to be elected in staggered three-year terms;

  .  limit the right of stockholders to remove directors;

  .  regulate how stockholders may present proposals or nominate directors
     for election at annual meetings of stockholders; and

                                       15
<PAGE>

  .  authorize our board of directors to issue preferred stock on one or more
     series, without stockholder approval.

   These provisions could:

  .  have the effect of delaying, deferring or preventing a change in control
     of our company;

  .  discourage bids for our class A common stock at a premium over the
     market price;

  .  lower the market price of, and the voting and other rights of the
     holders of, our class A common stock; or

  .  impede the ability of the holders of our class A common stock to change
     our management.

   In addition, our stockholders' agreement, credit facility and our senior
subordinated notes indenture contain limitations on our ability to enter into
change of control transactions. See "Certain Relationships and Related
Transactions," "Description of Indebtedness" and "Description of Capital
Stock--Anti-Takeover Provisions."

   Our business is subject to regulation by the FCC and state regulatory
commissions or similar state regulatory agencies in the states in which we
operate. This regulation may prevent some investors from owning our securities,
even if that ownership may be favorable to us. The FCC and some states have
statutes or regulations that would require an investor who acquires a specified
percentage of our securities or the securities of one of our subsidiaries to
obtain approval to own those securities from the FCC or the applicable state
commission.

You will experience immediate and substantial dilution.

   The initial public offering price is substantially higher than the net
tangible book value of each outstanding share of class A common stock.
Purchasers of class A common stock in this offering will suffer immediate and
substantial dilution. Based on our net tangible book deficit as of September
30, 1999, the dilution to investors in this offering in net tangible book
deficit will be $23.42 per share of the class A common stock.

This prospectus contains statements that are not statements of fact, and these
statements may prove to be incorrect, which may mean we need more capital than
we anticipate.

   All statements in this prospectus that are not statements of historical
facts are forward-looking statements. Forward-looking statements are inherently
speculative, and they may be incorrect. We base forward-looking statements in
this prospectus upon the following assumptions, among others, and they may be
incorrect:

  .  We will not incur any unanticipated costs in the construction of our
     network.

  .  We will be able to compete successfully in each of our markets.

  .  Demand for our services will meet wireless communications industry
     projections.

  .  Our network will satisfy the requirements described in our agreements
     with AT&T and support the services we expect to provide.

  .  We will be successful in working with AT&T and the other SunCom
     companies, as well as with other providers of wireless communications
     services and roaming partners, to ensure effective marketing of our
     network and the services we intend to offer.

  .  There will be no change in any governmental regulation or the
     administration of existing governmental regulations that requires a
     material change in the operation of our business.

   If one or more of these assumptions is incorrect, our actual business,
operations and financial results may differ materially from the expectations,
expressed or implied, in the forward-looking statements. Do not place undue
reliance on any forward-looking statements.

                              CONCURRENT OFFERING

   Concurrent with the shares offered by this prospectus, we are offering to
sell to AT&T Wireless by separate prospectus 1,950,000 shares of class A common
stock at a price per share of $18.65, which represents the initial public
offering price less the underwriting discount. In addition, if the
underwriters' over-allotment option is exercised, AT&T Wireless will also be
obligated to purchase at the same price the percentage of 295,000 additional
shares that is equal to the percentage of the 1,380,000 over-allotment shares
purchased by the underwriters. The consummation of the purchases by AT&T
Wireless in the concurrent offering will be conditioned upon consummation of
this offering and upon expiration of any applicable regulatory waiting periods.

                                USE OF PROCEEDS

   We estimate that the net proceeds from the sale of the 9,200,000 shares of
class A common stock in this offering and 1,950,000 shares in the concurrent
offering to AT&T Wireless will be approximately $206.6 million after deducting
the estimated underwriting discounts of this offering and estimated offering
expenses. If the underwriters exercise their over-allotment option in full,
which will require AT&T Wireless to purchase 295,000 shares in the concurrent
offering, subject to the conditions described above, we estimate that our
aggregate net proceeds will be approximately $237.9 million.

   We expect to use the net proceeds of this offering and the concurrent
offering for general corporate purposes, including capital expenditures in
connection with the expansion of our personal communications services network,
sales and marketing activities and working capital. We anticipate spending
approximately $95 million in the fourth quarter of 1999 and approximately $185
million in the year 2000 on capital expenditures to continue our network
construction, although actual amounts expended may vary significantly depending
upon the progress of the construction and other factors. These capital
expenditures are expected to be funded through a combination of the proceeds of
this offering and the concurrent offering, cash on hand, available bank and
vendor credit facilities and committed equity investments. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

   A portion of the net proceeds may also be used for approved acquisitions.
Other than the pending acquisitions of TeleCorp LMDS and additional airwaves in
Louisiana, we have no agreements or commitments with respect to any such
acquisition. However, we continually evaluate opportunities and enter into
discussions regarding possible acquisitions of licenses and properties that
will complement or extend our existing operations. We may incur substantial
additional debt to finance any future acquisitions. We do not currently expect
that we would acquire licenses in any new market unless we are able to extend
the AT&T agreements to cover our operations in that market.

   Pending such uses, the net proceeds of this offering and the concurrent
offering will be invested in short term, interest-bearing, investment grade
securities.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying any cash dividends on our capital stock in the
foreseeable future. We currently intend to retain future earnings, if any, to
finance the expansion of our business. Any future determination to pay
dividends will be at the discretion of our board of directors and will be
dependent upon then existing conditions, including our financial conditions and
results of operations, contractual restrictions, business prospects and other
factors that the board of directors considers relevant. Our ability to pay
dividends is restricted by the terms of our preferred stock, our senior
subordinated notes indenture and our senior credit facilities. See "Description
of Capital Stock" and "Description of Indebtedness."

                                 CAPITALIZATION

   The following table sets forth our capitalization as of September 30, 1999:

  .  on an actual basis,

  .  giving pro forma effect to our pending acquisitions of TeleCorp LMDS and
     the remaining minority interest of Viper Wireless that we do not
     currently own, and adjustments related to completed acquisitions during
     the first nine months of 1999, and

  .  on a pro forma as adjusted basis to give effect to the items described
     above, the sale of 9,200,000 shares of class A common stock at the
     initial public offering price of $20.00 per share, and the sale of
     1,950,000 shares of class A common stock to AT&T Wireless at a price of
     $18.65 per share

   This information should be read together with "Selected Historical and Pro
Forma Consolidated Financial Information," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Unaudited Pro
Forma Condensed Consolidated Financial Statements" and our other financial
statements and related notes included elsewhere in this prospectus.

                                    DILUTION

   If you invest in our class A common shares in this offering, your interest
will be diluted by an amount equal to the difference between the initial public
offering price per class A common share and the net tangible book value per
class A common share after this offering and the concurrent offering to AT&T
Wireless. We calculate net tangible book value, which is total assets less
intangible assets, total liabilities and net mandatorily redeemable preferred
stock, by the number of outstanding class A common shares. Our net tangible
book deficit as of September 30, 1999, was approximately $(497,632,810) or
approximately $(6.74) per class A common share. After the sale of the 9,200,000
class A common shares we are offering under this prospectus at the initial
public offering price per class A common share of $20.00, and the sale of
1,950,000 shares of class A common stock to AT&T Wireless in the concurrent
offering at a price of $18.65 per share, and after deducting underwriting
discounts in connection with this offering and our estimated offering expenses,
our net tangible book deficit as of September 30, 1999, would have been
approximately $(291,011,310) or approximately $(3.42) per class A common share.
This represents an immediate decrease in net tangible book deficit of $3.32 per
class A common share to existing shareholders and an immediate dilution of
$23.42 per class A common share to new investors in this offering. The
following table illustrates this dilution on a per class A common share basis:

   The following table summarizes on an unaudited pro forma basis as of

concurrent offering to AT&T Wireless before deducting the underwriting discount
in this offering and our estimated offering expenses.

</TABLE>

   The foregoing discussion and table assumes no exercise of outstanding
options and no conversion of our outstanding preferred or common stock after
September 30, 1999 into class A common stock. An aggregate of 16,051,110 shares
of class A common stock are issuable upon conversion of our outstanding class
C, class D and voting preference common stock and our series F preferred stock,
subject to FCC ownership restrictions no longer being applicable to us, and,
based on the September 30, 1999 liquidation preference of our series A
preferred stock of approximately $107.0 million and the initial public offering
price of $20.00 per share, 5,350,000 shares of our class A common stock would
be issuable upon conversion of our series A preferred stock. As of September
30, 1999, an aggregate of 552,505 shares of class A common stock were issuable
upon the exercise of options outstanding under our 1999 Stock Option Plan at a
weighted average exercise price of $0.0065 per share. If all such shares of
capital stock were converted to class A common shares and all such options were
exercised, the net tangible book deficit per share immediately after completion
of the offerings would be $(1.72). This represents an immediate dilution in net
tangible book deficit of $21.72 per share to purchasers of class A common
shares in this offering.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

Overview

   Our predecessor, TeleCorp Holding Corp., Inc., was incorporated on July 29,
1996 to participate in the FCC's auction of PCS licenses in April 1997, as a
designated entity and very small business, as defined by the FCC. TeleCorp
Holding obtained PCS licenses in the New Orleans, Memphis, Beaumont and Little
Rock basic trading areas, as well as other licenses that were subsequently
transferred to unrelated entities. The FCC has divided the country into major
trading areas which are each further subdivided into basic trading areas for
the purposes of PCS licensing.

   We were incorporated on November 14, 1997 by the controlling stockholders of
TeleCorp Holding, which subsequently became our wholly-owned subsidiary. In
January 1998, we entered into a venture with AT&T under which AT&T contributed
PCS licenses to us in exchange for an equity interest in us and sold additional
PCS licenses to us for $21.0 million. In July 1998, we received final FCC
approval for the venture and, in connection with the completion of the venture,
we entered into exclusivity, licensing, roaming and long distance agreements
with AT&T Wireless. We are AT&T's exclusive provider of PCS in our licensed
markets subject to AT&T's right to resell services on our network. We use the
AT&T brand name and logo together with the SunCom name and logo, giving equal
emphasis to each. We have acquired PCS licenses in a total of eight major
trading areas covering approximately 16.5 million people. See "Acquisition
History" below.

   For periods prior to 1999 we were a development stage company. In the first
quarter of 1999, we commenced commercial operations in each of our major
mainland U.S. markets, after having launched our New Orleans market for roaming
services in late December 1998. We launched our service in our Puerto Rico
markets on June 30, 1999.

 Revenue

   We derive our revenue from:

  .  Service. We sell wireless personal communications services. The various
     types of service revenue associated with personal communications
     services for our subscribers include monthly recurring charges and
     monthly non-recurring airtime charges for local, long distance and
     roaming airtime used in excess of pre-subscribed usage. Our customers'
     charges are rate plan dependent, based on the number of pooled minutes
     included in their plans. Service revenue also includes monthly non-
     recurring airtime usage associated with our prepaid subscribers and non-
     recurring activation and de-activation service charges.

  .  Equipment. We sell wireless personal communications handsets and
     accessories that are used by our customers in connection with our
     wireless services.

  .  Roaming. We charge monthly, non-recurring, per minute fees to other
     wireless companies whose customers use our network facilities to place
     and receive wireless services.

   Roaming revenue constituted the largest component of our revenue during the
first six months of this year. We expect that as our customer base grows, there
will be a significant change in our gross revenue mix. As a result, service
revenue is expected to increase while roaming revenues and equipment sales are
expected to decrease, as a percent of gross revenue. Roaming minutes on our
network are expected to increase as AT&T and other carriers increase the number
of subscribers on their networks. Under our reciprocal roaming agreement with
AT&T, our largest roaming partner, the amount we will receive and pay for
roaming minutes declines for each of the next several years.


                                       22
<PAGE>

   It appears that the wireless industry is experiencing a general trend
towards offering rate plans containing larger buckets of minutes. This is
expected to result in decreases in gross revenue per minute.

   We have autonomy in determining our pricing plans. We have developed our
pricing plans to be competitive and to emphasize the advantages of our service.
We may discount our pricing in order to obtain customers or in response to
downward pricing in the market for wireless communications services.

 Cost of Revenue

   Equipment. We purchase personal communications handsets and accessories from
third party vendors to resell to our customers for use in connection with our
services. The cost of handsets is, and is expected to remain, higher than the
resale price to the customer. We record as cost of revenue an amount
approximately equal to our revenue on equipment sales. We record the excess
cost of handsets as a sales and marketing operating expense. We do not
manufacture any of this equipment.

   Roaming Fees. We pay fees to other wireless communications companies based
on airtime usage of our customers on other communications networks. It is
expected that reciprocal roaming rates charged between us and other carriers
will decrease. We do not have any significant minimum purchase requirements
other than our obligation to purchase at least 15 million roaming minutes from
July 1999 to January 2002 from another wireless provider in Puerto Rico
relating to customers roaming outside our coverage area. We believe we will be
able to meet these minimum requirements.

   Clearinghouse Fees. We pay fees to an independent clearinghouse for
processing our call data records and performing monthly inter-carrier financial
settlements for all charges that we pay to other wireless companies when our
customers use their network, and that other wireless companies pay to us when
their customers use our network. We do not have any significant minimum
purchase requirements. These fees are based on the number of transactions
processed in a month.

   Variable Interconnect. We pay monthly charges associated with the connection
of our network with other carriers' networks. These fees are based on minutes
of use by our customers. This is known as interconnection. We do not have any
significant minimum purchase requirements.

   Variable Long Distance. We pay monthly usage charges to other communications
companies for long distance service provided to our customers. These variable
charges are based on our subscribers' usage, applied at pre-negotiated rates
with the other carriers. We do not have any significant minimum purchase
requirements other than an obligation to AT&T Wireless to purchase a minimum
number of minutes of traffic annually over a specified time period and a
specified number of dedicated voice and data leased lines in order for us to
retain preferred pricing rates. We believe we will be able to meet these
minimum requirements.

 Operating Expense

   Operations and development. Our operations and development expense includes
engineering operations and support, field technicians, network implementation
support, product development, and engineering management. This expense also
includes monthly recurring charges directly associated with the maintenance of
network facilities and equipment. Operations and development expense is
expected to increase as we expand our coverage and add subscribers. In future
periods, we expect that this expense will decrease as a percentage of gross
revenues.

   Selling and marketing. Our selling and marketing expense includes brand
management, external communications, retail distribution, sales training,
direct, indirect, third party and telemarketing support. We also record the
excess cost of handsets over the resale price as a cost of selling and
marketing. Selling and

                                       23
<PAGE>

marketing expense is expected to increase as we expand our coverage and add
subscribers. In future periods, we expect that this expense will decrease as a
percentage of gross revenues.

   General and administrative. Our general and administrative expense includes
customer support, billing, information technology, finance, accounting and
legal services. Although we expect general and administrative
expense to increase in future periods we expect this expense will decrease
significantly as a percentage of gross revenues.

   As a result of this offering, the value of some outstanding stock option and
restricted stock awards will become fixed. Some other awards will become fixed
upon FCC approval of the pending Viper Wireless transaction. Most of the
awards, however, will remain subject to vesting requirements over approximately
four years. We expect to record approximately $84.0 million on our balance
sheet as deferred compensation and additional paid-in capital as a result of
the fixing of these awards, based on the initial public offering price of
$20.00 per share. This amount will be amortized in the statement of operations
as additional compensation expense as the vesting requirements are met. We
expect to record a charge of approximately $29.7 million of the $84.0 million
on our statement of operations as compensation expense for the fourth quarter
of 1999 in connection with these awards.

   Depreciation and amortization. Depreciation of property and equipment is
computed using the straight-line method, generally over three to ten years,
based upon estimated useful lives. Leasehold improvements are amortized over
the lesser of the useful lives of the assets or the term of the lease. Network
development costs incurred to ready our network for use are capitalized.
Amortization of network development costs begins when the network equipment is
ready for its intended use and will be amortized over its estimated useful life
ranging from five to ten years. We began amortizing the cost of the PCS
licenses, microwave relocation costs, and capitalized interest in the first
quarter of 1999, when PCS services commenced in some of our basic trading
areas. Microwave relocation entails transferring business and public safety
companies from radio airwaves that overlap with the portion of the airwaves
covered by our business to other portions of the airwaves. Amortization is
calculated using the straight-line method over 40 years. The AT&T agreements
are amortized on a straight-line basis over the related contractual terms,
which range from three to ten years. Amortization of the AT&T exclusivity
agreement, long distance agreement and the intercarrier roamer services
agreement began once wireless services were available to its customers.
Amortization of the network membership license agreement began on July 17,
1998, the date of the finalization of the AT&T transaction.

   Capital expenditures. Our principal capital requirements for deployment of
our wireless network include installation of equipment and, to a lesser extent,
site development work.

   Interest Income (Expense). Interest income is earned primarily on our cash
and cash equivalents. Interest expense through September 30, 1999 consists of
interest due on our senior credit facilities, vendor financing, and debt owed
to the U.S. government related to our licenses. Interest payable on the Lucent
series A notes and the Lucent series B notes on or prior to May 11, 2004 will
be payable in additional series A and series B notes. Thereafter, interest will
be paid in arrears in cash on each six month and yearly anniversary of the
series A and series B closing date or, if cash interest payments are prohibited
under the senior credit facilities or a qualifying high yield debt offering, in
additional series A and series B notes. The U.S. government financing receives
quarterly interest payments, which commenced in July 1998 and continued for one
year thereafter, then quarterly principal and interest payments for the
remaining nine years.

Results of Operations

 Nine Months ended September 30, 1999 Compared to Nine Months ended September
30, 1998

   The Company, which launched commercial service in the first quarter of 1999,
grew its customer base to 75,723 at September 30, 1999.

                                       24
<PAGE>

   For the nine months ended September 30, 1999, service revenue was $18.9
million, equipment revenue totaled $10.3 million and roaming revenue was $18.9
million. We began offering wireless services in each of our major mainland U.S.
markets in the first quarter of 1999, and in Puerto Rico on June 30, 1999. We
generated no revenue for the nine months ended September 30, 1998.

   Cost of revenue, consisting mainly of cost of equipment and roaming fees,
for the nine months ended September 30, 1999 was $23.1 million. We did not
generate any cost of revenue for the nine months ended September 30, 1998.

   Operations and development expense for the nine months ended September 30,
1999 was $25.9 million. This expense was primarily related to the engineering
and operating staff required to implement and operate our network. For the nine
months ended September 30, 1998, operations and development expense was $3.5
million as the Company was preparing for commercial launch.

   Selling and marketing expense for the nine months ended September 30, 1999
was $39.7 million, as compared to $2.5 million for the nine months ended
September 30, 1998. This increase was due to salary and benefits for a
substantially larger sales and marketing staff, and all other direct sales
costs, including advertising, related to acquiring customers and providing
wireless services. During the nine months ended September 30, 1998 the Company
was preparing for commercial launch.

   General and administrative expense for the nine months ended September 30,
1999 was $38.9 million, as compared to $15.9 million for the nine months ended
September 30, 1998. The increase was due to the growth of billing expense
related to our increasing 1999 customer base, as well as the growth of our
infrastructure and staffing related to information technology, customer care,
finance and legal functions incurred in conjunction with the development and
rapid expansion of our markets. During the nine months ended September 30, 1998
the Company was preparing for commercial launch.

   Depreciation and amortization expense for the nine months ended September
30, 1999 was $34.8 million, as compared to $0.6 million for the nine months
ended September 30, 1998. This increase was related to the amortization on
personal communications services licenses and AT&T agreements, as well as the
depreciation of our fixed assets subsequent to the commercial launch of our
wireless service markets.

   Interest expense, net of interest income, for the nine months ended
September 30, 1999 was $29.6 million, as compared to $2.9 million for the nine
months ended September 30, 1998. This increase in net interest expenses was
related to borrowings under our senior subordinated discount notes of $344.3
million, our senior credit facilities of $225 million and the issuance of $42.5
million aggregate principal amount of notes under the vendor financing provided
by Lucent.

 Year ended December 31, 1998 Compared to Year ended December 31, 1997

   Revenue for the year ended December 31, 1998 was approximately $29,200. This
revenue resulted from servicing AT&T's roaming customers in our Louisiana
markets. We began offering wireless services in most of our major markets in
the first quarter of 1999. We generated no revenue for the year ended 1997.

   Operations and development expense for the year ended December 31, 1998, was
approximately $9.8 million. This expense was primarily related to an increase
in engineering and operating staff devoted to the implementation of future
operations of our network. There was no operations and development expense for
the year ended December 31, 1997.

   Selling and marketing expenses for the year ended December 31, 1998, was
approximately $6.3 million, as compared to approximately $0.3 million for the
year ended December 31, 1997. The year-over-year increase was due to the
increase in corporate and regional sales and marketing staff in order to
prepare for domestic market launches in the first quarter of 1999.

                                       25
<PAGE>

   General and administrative expense for the year ended December 31, 1998, was
approximately $26.2 million, as compared to approximately $2.6 million for the
year ended December 31, 1997. The year-over-year increase was due to the
development and growth of infrastructure and staffing related to information
technology, customer care and other administrative functions incurred in the
preparation for commercial launch of our markets in the first quarter of 1999.

   Depreciation and amortization expense for the year ended December 31, 1998,
was approximately $1.6 million, as compared to approximately $11,000 for the
year ended December 31, 1997. This expense was related to depreciation of
furniture, fixtures and office equipment, as well as the initiation of
amortization on AT&T agreements.

   Interest expense, net of interest income, for the year ended December 31,
1998, was approximately $7.2 million, as compared to approximately $0.4 million
for the year ended December 31, 1997. This interest expense was related to
notes payable to shareholders and affiliates. This increase in interest expense
was related to borrowings under the senior credit facilities of $225.0 million
since July 1998 and the issuance of $10.0 million aggregate principal amount of
notes under the vendor financing provided by Lucent.

 From July 29, 1996 (inception) to December 31, 1996

   Selling and marketing expense and general and administrative expense for the
period from July 29, 1996 (inception), to December 31, 1996, was approximately
$0.5 million, which were associated with salary, benefits and expenses of
administrative personnel, as well as legal and other costs associated with our
formation.

Acquisition History

   Following approval of our venture with AT&T by the FCC, we completed the
following acquisitions:

   On April 20, 1999, we completed the acquisition of PCS licenses covering the
Baton Rouge, Houma, Hammond and Lafayette, Louisiana basic trading areas from
Digital PCS. As consideration for these licenses, we issued to Digital PCS $2.3
million of our common and preferred stock, paid Digital PCS approximately $0.3
million in reimbursement of interest paid on U.S. government debt related to
the licenses and assumed $4.1 million of debt owed to the U.S. government
related to these licenses. This debt is shown on our balance sheet net of a
discount of $0.6 million reflecting the below market interest rate on the debt.
These licenses cover a population of approximately 1.6 million, including a
population of 1.2 million in Baton Rouge and Lafayette covered by licenses we
already owned. These licenses also cover areas contiguous to our existing
licensed area, including travel corridors, which provide us with opportunities
to expand our covered area.

   On May 25, 1999, we completed the acquisition of a PCS license and related
assets covering the San Juan major trading area from AT&T. On May 24, 1999, we
sold to AT&T $40.0 million of our series A and F preferred stock. On May 25,
1999, we purchased the license and related assets from AT&T for $96.5 million
in cash. In addition, we reimbursed AT&T $3.2 million for microwave relocation
and $1.5 million for other expenses it incurred in connection with the
acquisition. This license covers a population of approximately 3.9 million in
Puerto Rico and the U.S. Virgin Islands.

   On June 2, 1999, we completed the acquisition of PCS licenses covering the
Alexandria, Lake Charles and Monroe, Louisiana basic trading areas from
Wireless 2000. As consideration for these licenses, we issued to Wireless 2000
approximately $0.4 million of common and preferred stock, paid Wireless 2000
$0.2 million for its costs for microwave relocation related to the Monroe
license and $0.4 million in reimbursement of interest paid on government debt
related to their licenses, and assumed $7.4 million of debt owed to the U.S.
government related to these licenses. This debt is shown on our balance sheet
net of a discount of $1.0 million reflecting the below market interest rate on
the debt. These licenses cover a population of approximately 0.8 million. These
licenses also cover areas contiguous to our existing licensed area, including
travel corridors,

                                       26
<PAGE>

which provide us with opportunities to expand our covered area. We cannot,
without AT&T's consent, develop the markets covered by the Monroe license.

   Our agreements with AT&T were extended to cover these markets, except for a
portion of the Monroe basic trading area, upon the closing of the Louisiana and
Puerto Rico acquisitions.

   We participated in the FCC's reauction of PCS licenses for additional
licenses through Viper Wireless. On April 15, 1999, the FCC announced that the
reauction ended, and Viper Wireless was the high bidder for additional airwaves
in New Orleans, Houma and Alexandria, Louisiana, San Juan, Puerto Rico,
Jackson, Tennessee and Beaumont, Texas. The FCC granted us all of these
licenses. At present, TeleCorp Holding owns 85% of Viper Wireless, and Mr.
Vento and Mr. Sullivan together own the remaining 15%. Mr. Vento and Mr.
Sullivan together have voting control over Viper Wireless. On September 30,
1999, we solicited the approval of the FCC for the transfer of shares of Viper
Wireless we do not yet own to TeleCorp Holding for 503,022 shares of our class
A common stock and 1,111 shares of our series E preferred stock. Any
consolidation of Viper Wireless into us will be subject to a final FCC order
approving the transaction. In order to finance the acquisition of Viper
Wireless, AT&T and some of our other initial investors paid $32.3 million for
additional shares of our preferred and common stock.

Recent Developments

   Since September 30, 1999, we have entered into the following agreements:

   On October 18, 1999, we agreed to acquire TeleCorp LMDS, Inc. through an
exchange of all of the outstanding stock of TeleCorp LMDS for 834,300 shares of
our class A common stock and 2,700 shares of our series C preferred stock.
TeleCorp LMDS's stockholders are Mr. Vento, Mr. Sullivan and three of our
initial investors. By acquiring TeleCorp LMDS, we will gain local multipoint
distribution service licenses covering 1100 MHz of airwaves in the Little Rock,
Arkansas basic trading area and 150 MHz of airwaves in each of the Beaumont,
Texas, New Orleans, Louisiana, San Juan and Mayaguez, Puerto Rico, and U.S.
Virgin Islands basic trading areas. These licenses will provide us with
additional airwaves that we can use to carry portions of our PCS network
traffic in these markets.

   On October 14, 1999, we agreed to purchase 15 MHz of additional airwaves in
the Lake Charles, Louisiana basic trading area from Gulf Telecomm, LLC. As
consideration for the additional airwaves we will pay Gulf Telecomm $362,844 in
cash, assume approximately $2.3 million in FCC debt related to the license and
reimburse Gulf Telecomm for all interest it paid to the FCC on debt related to
the license from June, 1998 until the date the transaction is completed.

   Each of these agreements are subject to governmental approvals and other
customary conditions to closing and they may not close on schedule or at all.
From time to time, we enter into discussions regarding the acquisition of other
licenses, including swapping our licenses for those of other license holders.

Liquidity and Capital Resources

   Since inception, our activities have consisted principally of:

  .  hiring a management team;

  .  raising capital;

  .  negotiating strategic business relationships;

  .  planning and participating in the PCS auction;

  .  initiating research and development;

                                       27
<PAGE>

  .  conducting market research; and

  .  developing our wireless services offering and network.

   We have been relying on the proceeds from borrowings and issuances of
capital stock, rather than revenues, for our primary sources of cash flow. We
began commercial operations in December 1998 and began earning recurring
revenues by the end of the first quarter of 1999.

   Cash and cash equivalents totaled $80.4 million at September 30, 1999, as
compared to $111.7 million at December 31, 1998. This decrease was the result
of incoming cash provided by financing activities of $432.8 million, offset by
$87.6 million of cash used in operating activities and $376.5 million of cash
used in network development and investing activities.

   During the nine months ended September 30, 1999, we increased long-term debt
by $386.4 million and received $65.8 million of preferred stock proceeds and
receipt of preferred stock subscriptions receivable net of direct issuance
costs. Cash outlays for capital expenditures required to develop and construct
our network totaled $245.5 million. We spent $72.4 million to purchase PCS
licenses. In addition, we were required to deposit $43.6 million with the FCC
for other licenses during the nine months ended September 30, 1999. Cash used
in operating activities of $87.6 million for the nine months ended September
30, 1999 resulted from a net loss of $144.1 million that was partially offset
by non-cash charges of $56.8 million. Net change in assets and liabilities was
a reduction of $0.3 million.

   From inception through September 1998, our primary source of financing was
notes issued to our stockholders. In July 1996, we issued $0.5 million of
subordinated promissory notes to our stockholders. We converted these notes
into 50 shares of our series A preferred stock in April 1997. In December 1997,
we issued various promissory notes totaling $2.8 million to our stockholders.
We converted these notes into mandatorily redeemable preferred stock in July
1998. From January 1 to September 30, 1998, we borrowed approximately $22.5
million in the form of promissory notes to existing and prospective
stockholders to satisfy working capital needs. We converted these notes into
our equity in July 1998 in connection with the completion of the venture with
AT&T.

   From inception through November 15, for aggregate cash payments of $141.9
million and other consideration, we have issued 97,473 shares of series A
preferred stock, 210,608 shares of series C preferred stock, 49,417 shares of
series D preferred stock, 25,041 shares of series E preferred stock, 14,912,778
shares of series F preferred stock, 73,873,889 shares of class A common stock,
283,813 shares of class C common stock, 851,429 shares of class D common stock;
and 3,090 shares of voting preference stock. The class C, class D and voting
preference common stock are convertible into an aggregate of 1,138,332 shares
of class A common stock. The issuances have been in connection with capital
infusions as well as with acquisition of licenses and other assets by the
company, as described below. The primary recipients of these shares were CB
Capital Investors, L.P; Equity-Linked Investors--II; Hoak Communications
Partners, L.P; Whitney Equity Partners. L.P; Media/Communications Partners;
AT&T Wireless PCS, LLC; TWR Cellular, Inc; as well as Gerald Vento and Thomas
Sullivan and other management. See "Principal Stockholders and Beneficial
Ownership of Management."

   Our preferred stock is convertible into shares of our common stock at
various times and following various events as follows:

  .  our series A preferred stock is convertible into shares of our class A
     common stock after July 17, 2006 at a conversion rate equal to the
     liquidation preference, which was approximately $107.0 million as of
     September 30, 1999, divided by the market price of the class A common
     stock at the time of conversion;

  .  our series F preferred stock is convertible at any time into shares of
     our class A or class B common stock on a share for share basis.


                                       28
<PAGE>

   We may redeem:

  .  shares of our series A preferred stock after the tenth anniversary of
     its issuance; and

  .  shares of our series B, series C and series D preferred stock at any
     time;

at the liquidation preference for the shares being redeemed.

   The holders of our series A, series B, series C, series D and series E
preferred stock have the right to require us to redeem their shares after the
twentieth anniversary of their issuance time at the liquidation preference for
the shares being redeemed.

   Holders of our series A preferred stock are entitled to a quarterly dividend
equal to 10% per annum of that stock's accumulated liquidation preference. The
accumulated liquidation preference of our series A preferred stock was
approximately $107.0 million in aggregate as of September 30, 1999. We may
defer payment of this dividend until December 31, 2008, and we are currently
doing so.

   Holders of our series C, D and E preferred stock are not entitled to a
dividend except to the extent declared by our board. Those series of stock,
however, are entitled to an accumulated liquidation preference, which was
approximately $275.8 million in aggregate as of September 30, 1999. The
liquidation preference accretes at a rate of 6% per annum, compounded
quarterly.

   See "Description of Capital Stock" for additional information on the
dividends, liquidation preferences, rankings and voting rights of the capital
stock.

 Equity Commitments

   In connection with completion of the venture with AT&T, we received
unconditional and irrevocable equity commitments from our stockholders in the
aggregate amount of $128.0 million in return for the issuance of preferred and
common stock. As of September 30, 1999, approximately $55.5 million of the
equity commitments had been funded. The remaining equity commitments are
required to be funded in an installment of $36.3 million in July 2000 and $36.2
million in July 2001.

   We received additional irrevocable equity commitments from our stockholders
in the aggregate amount of $5.0 million in return for the issuance of preferred
and common stock in connection with the Digital PCS acquisition. Our
stockholders funded $2.2 million of these equity commitments on April 30, 1999,
and are required to fund $1.4 million in each of July 2000 and July 2001.

   We have received additional irrevocable equity commitments from our
stockholders in the aggregate amount of approximately $40.0 million in return
for the issuance of preferred and common stock in connection with the Puerto
Rico acquisition. We received $12.0 million of these commitments on May 24,
1999, and $6.0 million are required to be funded in December 1999 and $11.0
million are required to be funded on each of March 30, 2001 and March 30, 2002.

   We also received irrevocable equity commitments from our stockholders in the
amount of approximately $32.3 million in connection with Viper Wireless'
participation in the FCC's reauction of PCS licenses. We received approximately
$6.5 million of these equity commitments on May 14, 1999, approximately $11.0
million on July 15, 1999 and approximately $14.8 million on September 29, 1999.
In the aggregate, we have obtained $205.3 million of equity commitments, of
which $102.0 million had been funded as of September 30, 1999.

   These equity commitments cannot be amended without our consent and the
consent of AT&T and all of the other initial investors. In addition, the terms
of our senior subordinated discount notes and our bank and vendor credit
facilities restrict us from waiving or amending these commitments. The
foregoing equity commitments are also secured by pledges of the shares of our
capital stock issued to each initial investor, other

                                       29
<PAGE>

than certain shares of preferred stock. Those pledges have been assigned to our
senior lenders as security for our senior credit facilities. Transfers of
shares of our capital stock pledged to secure an equity commitment remain
subject to such pledge until the equity commitment is funded in full.

   In addition, pursuant to the stockholders' agreement between our initial
investors, Mr. Vento and Mr. Sullivan and us, the initial investors are
restricted from transferring their shares of common stock prior to July 2001,
except to affiliates. Any transfers by them of class A common stock are subject
to rights of first offer and tag-along and drag-along rights in favor of AT&T
and the other initial investors. In addition to the approval of our senior
lenders, the terms of the stockholders' agreement may be amended only if agreed
to in writing by us and the beneficial holders of a majority of the class A
common stock party to the stockholders' agreement, including AT&T Wireless, 66
2/3% of the class A common stock beneficially owned by our initial investors
other than AT&T, and 66 2/3% of the class A common stock beneficially owned by
Mr. Vento and Mr. Sullivan. Following the offering and the expiration or waiver
of the 180 day restriction on transfers described under "Underwriting," shares
of preferred stock may be transferred, subject, however, to the pledge
described above and to the continuing obligation of the investor to fund its
commitment.

 Senior Subordinated Discount Notes

   On April 20, 1999, we sold $575.0 million aggregate principal amount at
maturity of 11 5/8% senior subordinated discount notes due April 15, 2009. Cash
interest on these notes will not accrue or be payable prior to April 15, 2004.
From April 15, 2004, cash interest will accrue at a rate of 11 5/8% per annum
on the principal amount at maturity of the notes through and including the
maturity date and will be payable semi-annually on April 15 and October 15 of
each year. In connection with the sale of these notes, we received net proceeds
of approximately $317 million after deducting initial purchasers' discount and
issuance expenses of approximately $11 million.

 Senior Credit Facilities

   In July 1998, we entered into senior credit facilities with a group of
lenders for an aggregate amount of $525.0 million. In October 1999 we entered
into amendments to the senior credit facilities under which the amount of
credit available to us was increased to $560.0 million. Our senior credit
facilities currently provide for:

  .   a $150.0 million senior secured term loan that matures in January 2007,

  .   a $225.0 million senior secured term loan that matures in January 2008,

  .   a $150.0 million senior secured revolving credit facility that matures
     in January 2007, and

  .   a $35.0 million senior secured term loan that matures in May 2009.

   We must repay the term loans in quarterly installments, beginning in
September 2002, and the commitments to make loans under the revolving credit
facility automatically and permanently reduce beginning in April 2005. As of
September 30, 1999, $225.0 million had been drawn under the senior credit
facilities and was then accruing interest at an annual rate of 8.48%. See
"Description of Indebtedness--Senior Credit Facilities."

 Vendor Financing

   In May 1998, we entered into a vendor procurement contract with Lucent,
under which we agreed to purchase radio, call connecting and related equipment
and services for the development of our network. We also entered into a note
purchase agreement with Lucent under which Lucent agreed to provide us with
$80.0 million of junior subordinated vendor financing. This $80.0 million
consisted of $40.0 million aggregate principal amount of increasing rate Lucent
series A notes and $40.0 million aggregate principal amount of increasing rate
Lucent series B notes. We borrowed $40.0 million under the series B note
facility and repaid

                                       30

this amount and accrued interest thereon in April 1999 from proceeds of our
sale of senior subordinated discount notes. This amount cannot be reborrowed.
As of September 30, 1999, we had outstanding approximately $42.5 million of our
Lucent series A notes, including $1.6 million of Lucent series A notes issued
as payment of interest in kind, plus $0.9 million of additional accrued
interest and accruing interest at a rate per annum of 8.5% as of September 30,
1999. The amount outstanding under these series A notes and any future series A
note borrowings is subject to mandatory prepayment in an amount equal to 50% of
the excess of $198.0 million in net proceeds we receive from an equity offering
other than this offering and the concurrent offering and the issuance of
capital stock used to acquire related business or assets.

   In October 1999 we entered into an amended and restated note purchase
agreement with Lucent under which Lucent has agreed to purchase up to $12.5
million of new series A notes and up to $12.5 million of new series B notes
under a vendor expansion facility in connection with our prior acquisition of
licenses in the San Juan, Puerto Rico, Evansville Indiana, Paducah, Kentucky
and Alexandria and Lake Charles, Louisiana markets. The obligation of Lucent to
purchase notes under this vendor expansion facility is subject to a number of
conditions, including that we commit to purchase one wireless call connection
equipment site and 50 network equipment sites for each additional market from
Lucent.

   In addition, pursuant to the amended and restated note purchase agreement
Lucent has agreed to make available up to an additional $50.0 million of new
vendor financing not to exceed an amount equal to 30% of the value of
equipment, software and services provided by Lucent in connection with any
additional markets we acquire. This $50.0 million of availability is subject to
a reduction up to $20 million on a dollar for dollar basis of any additional
amounts Lucent otherwise lends to us for such purposes under our senior credit
facilities, exclusive of amounts Lucent lends to us under its existing
commitments under our senior credit facilities. Any notes purchased under this
facility would be divided equally between Lucent series A and series B notes.

   The terms of Lucent series A and series B notes issued under these expansion
facilities would be identical to the terms of the original Lucent series A and
series B notes as amended, including a maturity date of October 23, 2009.

   Any Lucent series B notes issued under these expansion facilities will
mature and will be subject to mandatory prepayment on a dollar for dollar basis
out of the net proceeds of any future public or private offering or sale of
debt securities, exclusive of any private placement notes issued to finance any
additional market and borrowings under the senior credit facilities or any
replacement facility.

   The senior subordinated discount notes represent a large portion of our
capital resources that do not have required scheduled payments of principal or
interest for five years from their issue date. Accordingly, they represent a
significant source of our liquidity without creating a capital requirement in
the near term.

 Capital Expenditures

   From inception through December 31, 1998, cash outlays for capital
expenditures were approximately $108.7 million. The continued construction of
our network and the marketing and distribution of wireless communications
products and services will require substantial additional capital. We will
incur significant amounts of debt to implement our business plan and will be
highly leveraged. We estimate that our capital commitments will be sufficient
to meet our total capital requirements through December 31, 2001, although if
we acquire additional licenses or properties, we may need to incur substantial
additional debt to meet our capital requirements. These requirements include:

  .  license acquisition costs;

  .  capital expenditures for network construction;

  .  operating cash flow losses and other working capital costs;

  .  debt service; and

  .  closing fees and expenses.

Capital expenditures from inception to September 30, 1999, were approximately
$354.2 million. Capital expenditures were approximately $245.5 million for the
first nine months of 1999. We estimate capital expenditures for the years ended
December 31, 1999, and December 31, 2000, will be approximately $355.0 million
and $185.0 million, respectively.

   As of September 30, 1999, we have approximately $20.5 million of debt owed
to the U.S. government related to some of our licenses. This debt is shown on
our balance sheet at $17.9 million net of discounts of $2.6 million reflecting
the below market interest rates on the debt. As of September 30, 1999, we owe
the U.S. government $9.2 million less a discount of $1.3 million, for the
acquisition of PCS licenses in New Orleans, Memphis, Beaumont and Little Rock
obtained during the 1997 auction. The terms of the notes include: an interest
rate of 6.25%, quarterly interest payments which commenced in July 1998 and
continued for the one year thereafter, then quarterly principal and interest
payments for the remaining nine years. The promissory notes are collateralized
by the underlying PCS licenses. As of September 30, 1999, we have approximately
$7.7 million of liabilities for microwave relocation obligations. Approximately
$5.3 million is required to be paid within the next year, and the remaining
$2.4 million is required to be paid in the following year. We do not expect to
incur significant additional microwave relocation costs for our existing
markets.

 Other

   During the nine months ended September 30, 1999, we completed the
acquisition of additional PCS licenses from Digital PCS, LLC and Wireless 2000,
Inc. As part of these acquisitions, we assumed additional U.S. government
financing with the FCC amounting to $11.6 million, less a discount of $1.6
million. The terms of the notes include an interest rate of 6.125% for notes
assumed from Digital PCS, LLC. and 7.00% for notes assumed from Wireless 2000,
Inc., quarterly interest payments for a two--year period and then quarterly
principal and interest payments for the remaining eight years.

   In May 1998, we entered into a vendor procurement contract with Lucent under
which we are permitted to purchase up to $285.0 million of radio, call
connecting and related equipment and services for the development of our
wireless communications network. Through September 30, 1999, we have purchased
approximately $194.5 million of equipment and services from Lucent.

   We have operating leases primarily related to retail store locations,
distribution outlets, office space and rent for our network development. The
terms of some of the leases include a reduction of rental payments and
scheduled rent increases at specified intervals during the term of the leases.
We are recognizing rent expense on a straight-line basis over the life of the
lease, which establishes deferred rent on the balance sheet. As of September
30, 1999, the aggregate minimum rental commitments under non-cancelable
operating leases are as follows:

</TABLE>

   Rental expense, which is recorded ratably over the lease terms, was
approximately $2,000, $157,000, $3.2 million and $9.7 million for the period
ended December 31, 1996 and for the years ended December 31, 1997, 1998, and
for the nine months ended September 30, 1999 respectively.

   We own more than 163 communications towers situated on leased sites in all
of our markets. We are considering entering into sale/leaseback transactions
and may do so if we can obtain terms acceptable to us.

   We have entered into a series of agreements for software licenses,
consulting, transition support and maintenance with various vendors. The total
future commitments under the agreements is approximately $6.0 million as of
September 30, 1999.

   We have entered into letters of credit to facilitate local business
activities. We are liable under the letters of credit for nonperformance of
certain criteria under the individual contracts. The total amount of
outstanding letters of credit was $1.5 million at September 30, 1999. The
outstanding letters of credit reduce the amount available to be drawn under our
senior credit facility.

   We believe that the net proceeds of this offering and the concurrent
offering, the capital we have raised to date and the other capital resources
currently available to us, which includes the funding of the irrevocable equity
commitments from our initial investors, will be sufficient to meet our
projected capital requirements through December 31, 2001. If we acquire
additional licenses or properties, we may need to incur substantial additional
debt to complete the acquisitions and construct and operate the acquired
properties. The network development requirements imposed by our agreements with
AT&T create significant capital requirements much of which will be covered by
indebtedness we incur. Our ability to meet our capital requirements is subject
to our ability to construct our network and obtain customers in accordance with
our plans and assumptions and a number of other risks and uncertainties
including those discussed under the heading "Risk Factors." The development of
our network may not be completed as projected and we may not be able to
generate positive cash flow. If any of our projections are incorrect, we may
not be able to meet our projected capital requirements.

Quantitative and Qualitative Disclosure About Market Risk

   We are not exposed to fluctuations in currency exchange rates since all of
our services are invoiced in U.S. dollars. We are exposed to the impact of
interest rate changes on our short-term cash investments, consisting of U.S.
Treasury obligations and other investments in respect of institutions with the
highest credit ratings, all of which have maturities of three months or less.
These short term investments carry a degree of interest rate risk. We believe
that the impact of a 10% increase or decline in interest rates would not be
material to our investment income.

                                       33
<PAGE>

   We use interest rate swaps to hedge the effects of fluctuations in interest
rates on our senior credit facilities. These transactions meet the requirements
for hedge accounting, including designation and correlation. These interest
rate swaps are managed in accordance with our policies and procedures. We do
not enter into these transactions for trading purposes. The resulting gains or
losses, measured by quoted market prices, are accounted for as part of the
transactions being hedged, except that losses not expected to be recovered upon
the completion of hedged transactions are expensed. Gains or losses associated
with interest rate swaps are computed as the difference between the interest
expense per the amount hedged using the fixed rate compared to a floating rate
over the term of the swap agreement. As of September 30, 1999, we have entered
into six interest rate swap agreements totaling $225.0 million to convert our
variable rate debt to fixed rate debt. The interest rate swaps had no material
impact on our consolidated financial statements as of and for the year ended
December 31, 1998 or the nine month period ended September 30, 1999.

Year 2000

   The year-2000 issue is the result of computer programs being written using
two digits, rather than four digits, to define the applicable year. Programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year-2000. This could result in a major system failure or
miscalculations, including an inability to process transactions, send invoices
or engage in similar normal business activities. Because we rely on computer
hardware and software, telecommunications and related service industries are
highly susceptible to the year-2000 issue.

   Over the past two years, as we purchased the various components that
comprise our internal information technology systems, we received
representations from our vendors that these components were year-2000
compliant. Our non-information technology systems may also be susceptible to
the year-2000 issues. In particular, our network equipment that connects calls
contains embedded components that are date sensitive. We have received
assurances from Lucent that all of our network hardware purchased from them is
year-2000 compliant.

   We recently engaged Cayenta.com, a nation-wide provider of year-2000
services. We and Cayenta.com formed a year-2000 committee, and initiated a
year-2000 readiness program that:

  .  is developing an enterprise plan for addressing the year-2000 situation;

  .  is providing an inventory of all hardware, software, and network assets;

  .  has reviewed vendor contracts to determine if year-2000 language is
     included;

  .  is conducting an assessment of year-2000 readiness of TeleCorp
     technology assets; and

  .  will recommend further testing and remediation, if applicable.

   The scope of this effort includes our Virginia headquarters as well as our
locations in Arkansas, Louisiana, New England, Tennessee, and Puerto Rico. The
Cayenta.com engagement will address wireless network infrastructure, internally
developed and third party vender-developed applications, information technology
networks, and issues at our data centers, call centers, and call connection
sites.

   We also depend upon the ability of AT&T, AT&T's roaming partners and
Electronic Data Systems to ensure that their software and equipment are year-
2000 compliant. We rely on AT&T to provide our customers with over-the-air
activation and roaming. We rely on Electronic Data Systems to provide
clearinghouse services.

   Our costs with respect to year-2000 compliance have been approximately $0.4
million through September 30, 1999, and we anticipate that our total costs in
evaluating our information technology system will not exceed $1.5 million,
including costs to build the necessary redundancy into our systems.


                                       34
<PAGE>

   Although we expect our systems will be year-2000 compliant on a timely
basis, they may not be, and the systems of other parties may not be year-2000
compliant on a timely basis or be compatible with our systems. We believe that
the greatest risk to our ability to provide communications services is the
failure of our service providers to be year-2000 compliant, especially those
service providers that provide local access and some of the billing systems
upon which our long distance communications service relies. In the event one of
our vendors is not year-2000 compliant and their noncompliance affects us, we
believe that this effect will cause only a temporary disruption of our service,
if at all. Although we cannot estimate the material lost revenue due to this
worst case scenario, we do not believe that such losses, if any, will be
significant.

                      THE WIRELESS COMMUNICATIONS INDUSTRY

   Wireless communications systems use a variety of radio airwaves to transmit
voice and data. The wireless communications industry includes one-way radio
applications, such as paging or beeper services, and two-way radio
applications, such as personal communications services, or PCS, cellular
telephone and other technologies. Each application is licensed and operates in
a distinct radio airwave block.

   Since the introduction of commercial cellular service in 1983, the wireless
communications industry has experienced dramatic growth. The number of wireless
subscribers in the United States has increased from an estimated 340,000 at the
end of 1985 to over 69 million as of December 31, 1998, according to the
Cellular Telecommunications Industry Association, an international association
for the wireless industry. Paul Kagan Associates, an independent media and
telecommunications association, estimates that the number of wireless users
will increase to 142 million by 2003, with PCS users representing nearly 34% of
total users, a significant increase over the approximately 11% of total users
represented by PCS today. The following chart illustrates the estimated annual
growth in U.S. wireless communications customers, who use cellular, PCS or
other two-way wireless services through December 31, 1998:

    providers.

   In the wireless communications industry, there are two principal services
licensed by the FCC for transmitting voice and data signals: PCS and cellular.
Personal communications services, or PCS, is a term commonly used in the United
States to refer to service carried over the 1850 MHz to 1990 MHz portion of the
radio airwaves. Megahertz, or MHz, is a method of measuring radio airwaves.
Cellular is a term commonly used in the United States to refer to service
carried over the 824 MHz to 893 MHz portion of the radio airwaves. Cellular
service is the predominant form of wireless voice communications service
available. Cellular systems were originally analog-based systems, although
digital technology has been introduced in some markets. PCS systems use digital
technology. Analog technology currently has several limitations, including lack
of privacy and limited capacity. Digital systems convert voice or data signals
into a stream of digits that is compressed before transmission, enabling a
single radio channel to carry multiple simultaneous signal transmissions. This
enhanced capacity, along with improvements in digital signaling, allows
digital-based wireless technologies to offer new and enhanced services, such as
greater call privacy and robust data transmission features, including mobile
office applications like facsimile, e-mail and wireless connections to
computer/data networks and including the Internet. See "Business--Government
Regulation" for a discussion of the FCC auction process and allocation of
wireless licenses.

 Operation of Wireless Communications Systems

   Wireless communications system service areas, whether PCS, cellular or other
technologies, are divided into multiple units. Each unit contains a
transmitter, a receiver and signaling equipment to transmit wireless signals to
individual phones. This equipment is connected by telephone lines or microwave
signals to call connection equipment that uses computers to control the
operation of the communications system for the entire service area. The call
connection equipment controls the connection of calls and the connection of the
wireless

                                       36
<PAGE>

network to local telephone systems and long distance carriers. The system
controls the transfer of calls from equipment site to equipment site as a
subscriber's handset travels, coordinates calls to and from handsets, allocates
calls among the network equipment sites within the system and connects calls to
the local telephone system or to a long distance telephone carrier. Wireless
communications providers must establish agreements with local and long distance
carriers that allow them to pass calls, or interconnect, thereby integrating
their system with the existing communications system.

   Because the signal strength of a transmission between a handset and a
network equipment site declines as the handset moves away from the network
equipment site, the wireless network monitors the signal strength of calls in
progress. When the signal strength of a call declines to a predetermined level,
the call connection equipment may transfer the call to another network
equipment site where the signal is stronger. If a handset leaves the service
area of a PCS or cellular system, the call is disconnected unless there is a
technical connection with the adjacent system. If there is a technical
connection with the adjacent system, the customer may roam onto the adjacent
system.

   Analog handsets that use the cellular portion of the airwaves are
functionally compatible with cellular systems in all markets in the United
States. As a result, these handsets may be used wherever a subscriber is
located, as long as a cellular system is operational in the area and either the
service provider's system covers such area or a roaming arrangement exists with
a provider covering the area.

   Although PCS and cellular systems use similar technologies and hardware,
they operate on different portions of the airwaves and use different technical
and network standards. Use of advanced handsets makes it possible for users of
one type of system to roam on a different type of system outside of their
service area, and to transfer calls from one type of system to another if the
appropriate agreements are in place and the networks are properly configured to
transfer calls from one system to the next.

   Currently, PCS systems operate under one of three principal digital signal
transmission technological standards that various operators and vendors have
proposed for use in PCS systems: TDMA, CDMA or GSM. TDMA and GSM are both time
division-based standards but are incompatible with each other and with CDMA.
Accordingly, a subscriber of a system that uses TDMA technology is unable to
use a TDMA handset when travelling in an area not served by TDMA-based PCS
operators, unless the subscriber carries a special handset that permits the
subscriber to use the analog or digital system on the cellular portion of the
airwaves in that area and the appropriate agreements are in place.

   With an advanced handset, a user can place or receive calls using:

  .  a PCS system using the technological standard with which the handset is
     compatible;

  .  a digital system on the cellular portion of the airwaves using the
     corresponding technological standard; or

  .  an analog system on the cellular portion of the airwaves.

   If a PCS system operated by the service provider or covered by a roaming
agreement is operating in the area, the call will be placed via this system. If
there is no PCS system providing coverage, the call will be placed through a
digital system on the cellular portion of the airwaves operating in the area
and providing coverage to the user, and if no digital system on the cellular
portion of the airwaves is providing coverage, the call will be connected over
an analog system that uses the cellular portion of the airwaves providing
coverage. These handsets allow for a call in progress to be handed off to an
adjacent system, whether the same mode or band or otherwise, without
interruption if the appropriate agreements are in place. Prior generations of
handsets would cut off the call when the handset left the coverage of one
system and would require the customer to place the call again using the
adjacent system.

                                    BUSINESS

   We are the largest AT&T Wireless affiliate in the United States, with
licenses covering approximately 16.5 million people. We provide wireless PCS in
selected markets in the south-central and northeast United States and in Puerto
Rico, encompassing eight of the 100 largest metropolitan areas in the United
States. Commencing with the launch of our New Orleans market in February 1999,
we have successfully launched our services in 21 markets, including all of our
major markets, and currently have more than 100,000 subscribers. Our senior
management team has substantial experience in the wireless communications
industry with companies such as AT&T, Bell Atlantic and Sprint PCS.

   We entered into a venture with AT&T in July 1998 under which AT&T
contributed PCS licenses to us in exchange for ownership in our company. We are
AT&T's exclusive provider of wireless mobility services using equal emphasis
co-branding with AT&T in our covered markets, subject to AT&T's right to resell
services on our network. We have the right to use the AT&T brand name and logo
together with our SunCom brand name and logo, giving equal emphasis to each. We
are AT&T's preferred roaming partner for digital subscribers in our markets.
Additionally, our relationship with AT&T allows us to provide coast-to-coast
coverage to our customers.

   Our PCS licenses include several major population centers and popular
vacation destinations such as:

  .  San Juan, Puerto Rico and the U.S. Virgin Islands;

  .  New Orleans and Baton Rouge, Louisiana;

  .  Memphis, Tennessee;

  .  Little Rock, Arkansas;

  .  Manchester, Concord and Nashua, New Hampshire; and

  .  Worcester, Cape Cod, Martha's Vineyard and Nantucket, Massachusetts.

   Our launched networks covered approximately 65% of our licensed population
as of September 30, 1999, and by the end of 1999 we expect our network will
cover approximately 75% of our licensed population.

   Our goal is to provide our customers with simple-to-buy, easy-to-use
wireless services, including coverage across the nation, superior call quality,
competitive pricing and personalized customer care.

   We market our services through company stores, retail outlets, through our
direct corporate and telemarketing sales forces, and on the Internet through
our website. We have a strong distribution presence in our markets with 35
company-owned stores and more than 500 retail outlets where consumers can
purchase our services, including Best Buy, Circuit City, Office Depot, Office
Max, Staples and Radio Shack. As of September 30, 1999, we employed
approximately 340 sales employees, 84 of whom were dedicated to business-to-
business sales activities. Our affiliation with AT&T enables us to leverage its
marketing and sales efforts in our markets.

Strategic Alliance with AT&T

   One of our most important competitive advantages is our strategic alliance
with AT&T. In order to rapidly develop some of its wireless communications
markets, AT&T Wireless has focused on constructing its own network in selected
cities and has entered into agreements with independent wireless operators,
such as us, to construct and operate wireless networks in other markets. Our
strategic alliance with AT&T Wireless provides us with many business,
operational and marketing advantages, including:

  .  Exclusivity. We are AT&T's exclusive provider of wireless mobility
     services using equal emphasis co-branding with AT&T in our covered
     markets, subject to AT&T's right to resell services on our network.


                                       38
<PAGE>

  .  Brand. We have the right to use the AT&T brand name and logo together
     with our SunCom brand name and logo in our markets, giving equal
     emphasis to each.

  .  Roaming. We are AT&T's preferred roaming partner for digital subscribers
     in our markets. Our roaming revenues increased from approximately $1.9
     million in the first quarter of 1999 to approximately $9.5 million in
     the third quarter. We believe our AT&T affiliation will continue to
     provide us with a valuable base of recurring roaming revenue.

  .  Coast-to-Coast Coverage. Outside our markets, our wireless customers can
     place and receive calls in AT&T Wireless' markets and the markets of
     AT&T Wireless' other roaming partners. We believe our ability to offer
     coast-to-coast coverage is a competitive advantage as users increasingly
     choose national rate plans. As of September 30, 1999, 19% of our
     customers have chosen one of our national SunRate pricing plans.

  .  Products and Services. We receive preferred terms on selected products
     and services, including handsets, infrastructure equipment and back
     office support from companies who provide these products and services to
     AT&T.

  .  Marketing. We benefit from AT&T's nationwide marketing and advertising
     campaigns, including the success of the AT&T Digital One Rate SM plans,
     in the marketing of our own national SunRate plans. In addition, we are
     working with AT&T's national sales representatives to jointly market our
     wireless services to AT&T corporate customers located in our markets.

Competitive Strengths

   In addition to the advantages provided by our strategic alliance with AT&T,
we have the following competitive strengths:

  .  Attractive Markets. Our markets have favorable demographic
     characteristics for personal communications services. According to
     industry analysts, the average population density of our markets is
     approximately 30% above the national average. We believe our markets are
     strategically important to AT&T because they are located near or
     adjacent to traffic corridors in and around large markets such as
     Boston, Houston and St. Louis. Our markets include major population and
     business centers and vacation destinations that attract an estimated 39
     million visitors per year. Most of our markets are also adjacent to the
     markets of the other SunCom companies.

  .  Experienced and Incentivized Management. Our 21 member senior management
     team has an average of 11 years of experience with companies such as
     AT&T, Bell Atlantic, BellSouth, SBC Communications, ALLTEL and Sprint
     PCS. Together, they will beneficially own approximately 11% of our class
     A common stock on a fully-diluted basis upon completion of this offering
     and the concurrent offering. Our top three executives are:

    .  Gerald Vento, our co-founder and Chief Executive Officer, who has 20
       years of experience in communications and previously served as Chief
       Executive Officer of Sprint Spectrum/American PCS, L.P., leading the
       development of the first PCS network launched in North America.

    .  Thomas Sullivan, our co-founder, Executive Vice President and Chief
       Financial Officer, who formerly served as President of TeleCorp
       Holding, our predecessor company, and co-head of the
       telecommunications law practice at McDermott, Will & Emery.

    .  Julie Dobson, our Chief Operating Officer, who has extensive
       operating experience in the telecommunications industry, including
       18 years at Bell Atlantic, most recently as President of the New
       York region of Bell Atlantic Mobile Systems.

  .  Substantial Airwave Capacity. We have licenses with a minimum of 35 MHz
     of airwaves in our major urban markets of San Juan and New Orleans and
     30 MHz in Little Rock and Memphis. These

                                       39
<PAGE>

     amounts are equal to or greater than those held by each of our principal
     competitors in each of these markets. We believe these amounts of
     airwaves will enable us to competitively deploy new and enhanced voice
     and data services. This capacity will also permit us to provide service
     to the increasing number of wireless users and to service increased use
     by subscribers.

  .  Strong Capital Base. Upon completion of this offering and the concurrent
     offering we will have approximately $1.6 billion of funded and committed
     capital. We believe our capital resources, including the proceeds of
     this offering, will be sufficient to fund our current business plan,
     including capital expenditures and operating losses, through December
     31, 2001. Our initial investors included AT&T, Chase Capital, Desai
     Associates, Hoak Capital Corporation, J.H. Whitney & Co., M/C Partners,
     One Liberty Fund, Toronto Dominion Investments, and Northwood Capital
     Partners.

  .  Advanced Digital Technology. We are building our network using TDMA
     technology, which makes our network compatible with AT&T's network and
     other TDMA networks. TDMA technology allows enhanced features and
     services relative to analog cellular service, including extended battery
     life, integrated voicemail, paging, fax and e-mail delivery, enhanced
     voice privacy and short-messaging capability. Investment in TDMA product
     development has led to the development of an advanced generation of
     handsets capable of delivering stand-by battery life of up to 14 days.
     We believe that wireless users place great value on the convenience and
     reliability afforded by this technological advance. TDMA provides high
     network call clarity and in-building penetration. TDMA provides network
     capacity at least three times greater than existing analog cellular
     networks, which results in operating cost advantages. The increased
     volume of TDMA users has driven down handset prices and has increased
     the importance of TDMA as an industry standard.

Business Strategy

   Our goal is to become the leading provider of wireless personal
communications services in each of our markets, by providing our customers
with simple-to-buy and easy-to-use wireless services, including coverage
across the nation, superior call quality, competitive pricing and personalized
customer care. The elements of our strategy to achieve these objectives are:

  .  Leverage AT&T Relationship. We receive numerous benefits from AT&T,
     including market exclusivity, co-branding, roaming and coast-to-coast
     coverage, and preferred terms on selected products and services. Also,
     we benefit from AT&T's nationwide marketing and advertising campaigns,
     including those for the AT&T Digital One Rate SM plans, in the marketing
     of our national SunRate plans. In addition, we are working with AT&T's
     national sales representatives to jointly market our wireless services
     to AT&T corporate customers located in our markets.

  .  Provide Coast-to-Coast Coverage. Our market research indicates that
     scope and quality of coverage are extremely important to customers in
     their choice of a wireless service provider. We have designed extensive
     local calling areas, and we offer coast-to-coast coverage through our
     arrangements with AT&T Wireless and its roaming partners. Our network
     covers those areas where people are most likely to take advantage of
     wireless coverage, such as suburbs, metropolitan areas and vacation
     locations: the places where they live, work and play.

  .  Offer Superior Call Quality. We are committed to making the capital
     investment required to develop a superior network. We intend to invest
     approximately $55 per covered person in our licensed markets for the
     construction of our currently planned network, which we believe will
     ensure consistent quality performance and result in a high level of
     customer satisfaction. Our capital investment is designed to provide a
     highly reliable network as measured by performance factors such as
     percentage of call completion and number of dropped calls. We maintain a
     state-of-the-art network operations center and, to ensure continuous
     monitoring and maintenance of our network, we have a disaster recovery
     plan.

                                      40
<PAGE>

  .  Provide Enhanced Value at Low Cost. We offer our customers advanced
     services and features at competitive prices. Our pricing plans are
     designed to promote the use of wireless services by enhancing the value
     of our services to our customers. We include usage enhancing features
     such as call waiting, three-way conference calling, and short message
     service in our basic packages. We market our service with a simple, all-
     in-one focus: digital phone, pager and voice mail. We offer our
     customers affordable, simple calling plans, and we take advantage of the
     coast-to-coast reach of AT&T and its roaming partners. Our national
     SunRate plans are similar to AT&T Digital One Rate SM plans in which
     minutes can generally be used throughout the United States without
     paying additional roaming fees or long distance charges. We believe we
     can offer competitive services because of the cost advantages provided
     by our agreements with AT&T and the other SunCom companies, the cost-
     effective characteristics of TDMA and our centralized administrative
     functions and efficient distribution.

  .  Deliver Quality Customer Care. We serve our customers from our state-of-
     the-art facility in Memphis, Tennessee, which houses our customer
     service, collections and anti-fraud personnel. Convergys, a leading
     provider of outsourced call center services, provides backup call center
     support and, for our Spanish speaking customers, bilingual customer
     service from two facilities in Florida. We have implemented a "one call
     resolution" approach to customer care through the use of customer
     support tools such as an advanced diagnostic mechanism and access to
     online reference information. In addition, we emphasize proactive and
     timely customer service, including welcome packages and anniversary
     calls. Finally, we support our customer care initiatives through
     employee compensation plans based on subscriber satisfaction and
     retention.

Marketing Strategy

   We believe that our affiliation with the AT&T brand name and the distinctive
advantages of our TDMA network, combined with our simple-to-buy and easy-to-use
philosophy, will allow us to expand our customer base by capturing significant
market share from existing providers of wireless services in our markets.
Additionally, we expect to attract new users to wireless. We developed our
marketing strategy on the basis of extensive market research in each of our
markets. This research indicates that limited coverage of existing wireless
systems, relatively high costs, inconsistent performance and overall confusion
about wireless services drive subscriber dissatisfaction and reduce the
attractiveness of wireless services for potential new subscribers.

   We are focusing our marketing efforts on four primary market segments:

     .  corporate accounts;

     .  current wireless users;

     .  individuals with the intent to purchase a wireless product within six
  months; and

     .  prepaid subscribers.

   For each segment, we are creating a specific marketing program, including a
service package, pricing plan and promotional strategy. We believe that
targeted service offerings will increase customer loyalty and satisfaction,
reducing customer turnover.

   The following are key components of our marketing strategy:

 Branding

   We market our wireless services as "SunCom, Member of the AT&T Wireless
Network" and use the globally recognized AT&T brand name and logo in equal size
and prominence with the SunCom brand name and logo. We believe that consumers
associate the AT&T brand with reliability and quality.

   We have entered into agreements with Triton PCS and Tritel Communications,
other companies similarly affiliated with AT&T, to adopt a common regional
brand, SunCom. We and the other SunCom companies are establishing the SunCom
brand as a strong local presence with a service area covering a population of
approximately 43.0 million. We enjoy preferred pricing on equipment, handset
packaging and distribution by virtue of our affiliation with AT&T and the other
SunCom companies.

 Advertising/Promotion

   We believe that the most successful marketing strategy is to establish a
strong local presence in each of our markets. We are directing our media
efforts at the community level by advertising in local publications and
sponsoring local and regional events. We combine these local efforts with mass
market media, including television, radio, newspaper, magazine, outdoor and
Internet advertisements, to promote the SunCom and AT&T brands in the markets
we serve. Outside advertising agencies support our brand campaigns, and also
develop newspaper, radio and web page advertisements to promote specific
product offerings and direct marketing programs for targeted audiences. All of
our advertising materials use the SunCom and AT&T names and the tagline
"SunCom, Member of the AT&T Wireless Network."

 Pricing

   Our pricing plans are designed to be competitive and straightforward,
offering large buckets of minutes, large local calling areas and usage
enhancing features. We offer pricing plans tailored for our market segments,
including local, regional and national pricing plans. We also offer shared
minute pools that are available for businesses and families who have multiple
wireless users who want to share the bucket of minutes. Through September 30,
1999 our average usage per subscriber was approximately 420 minutes per month.

                                       43
<PAGE>

   We believe the pre-paid subscriber segment represents a large market
opportunity, and we offer pricing plans that will drive growth in these
categories. Pre-pay plans provide an opportunity for individuals whose credit
profiles would not otherwise allow them access to wireless communications to
take advantage of our services. In addition, our pre-pay plans provide an
attractive alternative for families and business users to control the usage of
family members or employees. We also structure our plans to be attractive to
the youth market, who we believe want to pay as they use the service. We
believe we differentiate ourselves from existing wireless competitors by
providing our pre-paid subscribers the same digital services and features
available to other customer segments. Our customers can use pre-pay service
virtually anywhere in the United States on our network, on AT&T's network or
through AT&T's extensive network of roaming agreements. Additionally, our pre-
pay customers hear a "whispered" announcement of time remaining in their
account before each call they place, which allows them to control usage and
reduce balance inquiries to customer service. By contrast, typical pre-pay
plans of our competitors limit service to their networks and usually provide
fewer features and a narrow selection of handsets. As of September 30, 1999,
prepay customers represented approximately 25% of our total subscribers.

   AT&T introduced AT&T Digital One Rate SM in May 1998, a suite of rate plans
that allows customers to purchase a large bucket of minutes per month that can
be used locally, or across the U.S., on AT&T's wireless network and its
extensive network of roaming partners for a fixed price with no additional
roaming or long distance charges. We believe AT&T Digital One Rate SM and other
competing flat rate plans are causing shifts in calling patterns in the
wireless industry. As of June 30, 1999, AT&T has reported over 1.5 million
subscribers on the AT&T Digital One Rate SM plans, and reported they were
adding an additional 100,000 subscribers a month. We believe growth in this
category will provide us a valuable roaming revenue stream as AT&T Digital One
Rate SM subscribers use their minutes while visiting our networks.

   We are able to offer a similar national SunRate plan by virtue of our
relationship with AT&T. Competing flat rate plans often limit flat rate usage
to the competitor's own networks. We are able to offer a differentiated
national rate plan by virtue of our roaming arrangements with AT&T and its
roaming partners. Through September 30, 1999, 19% of our subscribers had chosen
a national SunRate price plan.

   We believe our pricing policies differentiate us from our competition
through simplicity and design. We offer 12 price plans per region, on average,
and we design our plans to encourage customers to enter into long-term
agreements. As of September 30, 1999, approximately 50% of our total
subscribers, and approximately 75% of our total subscribers other than pre-pay
customers, were on annual contracts.

 Handsets

   We sell our service exclusively with handsets that are compatible with
wireless communications systems that operate using digital service on the PCS
portion of the airwaves, as well as digital and analog service on the cellular
portion of the airwaves. Through the use of technologically advanced Nokia,
Ericsson and Motorola handsets, our customers can use their phones across a
variety of wireless networks.

Service and Features

 Wireless Calling

   Our primary service is wireless calling, which features advanced handsets,
enhanced voice clarity, improved protection from eavesdropping and a broad
feature set. Our basic wireless service offering includes caller
identification, three-way conference calling, call waiting, voicemail, paging
and short-messaging.

 Feature-Rich Handsets

   As part of our basic service offering, we provide easy-to-use, interactive
menu-driven handsets that can be activated over the air. These handsets
primarily feature word prompts and easy-to-use menus rather than numeric codes
to operate handset functions. These handsets allow mobile access to e-mail and
other Internet services.

                                       44
<PAGE>

 Extended Battery Life

   Our advanced handsets offer significantly extended battery life over earlier
technologies, providing up to 14 days of stand-by battery life. Handsets
operating on a digital system are capable of "sleep-mode" while turned on but
not in use, improving efficiency and extending battery life. We expect that
this feature will increase usage, especially for incoming calls, as users will
be able to leave the phone on for significantly longer periods. The use of
these handsets further extends battery life by using a digital system for
roaming when in areas covered by digital systems.

 Improved Voice Quality

   We believe the version of TDMA we are using offers significantly improved
voice quality, more powerful error correction, less susceptibility to call
fading and enhanced interference rejection, which results in fewer dropped
calls compared to earlier versions of TDMA.

 Voice Privacy and Call Security

   Digital technology is inherently more secure than analog technologies. This
security provides increased voice privacy and enhanced fraud protection for our
customers.

 Wireless Services Inside Buildings

   As the use of wireless devices becomes more widespread, consumers
increasingly are demanding wireless services which extend into office
buildings, subways, airports, shopping centers and private homes. We use large
numbers of small network equipment sites to offer corporate users full coverage
inside buildings of outside calls. We also provide intra-office wireless
communications capabilities letting the user dial office extensions without the
need to dial the complete telephone number. In addition, we are working with a
number of hardware and software suppliers to develop next generation wireless
office services including the use of small network equipment sites within a
building that circumvent the local carrier.

 Data and Internet Services

   Because of the quality of digital signal transmission, wireless
communications systems are suitable for the transmission of wireless data
services such as applications providing weather reports, sports summaries,
stock quotes, monitoring of alarm systems and Internet access.

 Bundling and Affinity Marketing

   We may bundle our wireless communications services with other communications
services, including discounted long distance services, through strategic
alliances and resale agreements with AT&T and others. We also may offer service
options in partnership with local business and affinity marketing groups.
Examples of these arrangements include offering wireless services with utility
services, banking services, cable television, Internet access or alarm
monitoring services in conjunction with local information services. These
offerings provide the customer access to information, such as account status,
weather and traffic reports, stock quotes, sports scores and text messages from
any location.

Sales and Distribution

   Our sales strategy is to use a balanced mix of distribution channels to
maximize penetration within our licensed service area while minimizing customer
acquisition costs. Our channels include a network of company stores, nationally
recognized retailers, a direct sales force for corporate and business
customers, regional and local mass merchandisers, telesales, direct mail and
on-line sales. We also work with AT&T's sales channels to cooperatively
exchange leads and develop new business.

                                       45
<PAGE>

   We invest in training to ensure that knowledgeable staff is communicating
with customers and potential customers. We also take advantage of over-the-air
activation features available through our digital technology. Our goal is to
let customers use their phone within ten minutes of deciding to purchase the
handset. We provide point of sale materials and tools to educate customers on
their coverage areas and how to use the handset. We differentiate ourselves
from our competition by letting customers participate in the selection of their
phone number, and we offer a variety of custom faceplates to make a customer's
phone unique. We believe these tools, along with educating the customer, will
lead to reduced customer turnover.

 Company Stores

   We have opened 35 company stores for the distribution and sale of our
handsets and services. We believe that company stores offer a considerable
competitive advantage by providing a strong local presence. We also believe
that company stores offer one of the lowest customer acquisition costs among
our different distribution channels. Sales representatives in company stores
receive in-depth training to allow them to explain wireless communications
services simply and clearly. We believe this process distinguishes us from our
competitors and will increase subscribership within our markets. Our stores
range in size from small kiosks to 3600 square foot stores in the principal
retail district in each market. We expect to have a total of 45 SunCom stores
open by the end of 1999.

 Retail Outlets

   We have negotiated distribution agreements with national and regional mass
merchandisers and consumer electronics retailers, including Circuit City,
Cellular Warehouse, Metrocall, Office Depot, Staples, Best Buy and Office Max.
In Puerto Rico, we have relationships with Farmacia El Amal, Let's Talk
Wireless and Beeper Connections and Radio Shack. We currently have over 500
retail outlet locations where customers can purchase our services. We chose
these distributors based upon their ability to reach our target customers in
our service area. In some of these retail store locations, we are implementing
a store-within-a-store concept, which uses visual merchandising to leverage the
brand awareness created by both SunCom and AT&T advertising. The ease of
distribution of shrink-wrapped handsets appeals to mass merchandisers who have
altered their in-store merchandising to reflect the changing wireless
marketplace.

 Direct Sales

   We focus our direct sales distribution channel on high-revenue, high-profit
corporate users. Our direct corporate sales force consists of approximately 85
dedicated professionals targeting the wireless decision maker within large
corporations. We also benefit from AT&T's national corporate accounts sales
force. AT&T, in conjunction with us, supports marketing of our services to
AT&T's large national accounts located in our service areas. We have formed
regional advisory groups as an additional way to interface with corporate
customers in our markets. These advisory groups are comprised of local business
leaders, who are also wireless users or prospective users, and are designed to
provide timely feedback regarding our proposed wireless offerings and establish
a customer base prior to launch. We expect our direct sales force to grow to
approximately 135 business account executives by year end 1999.

 Direct Marketing

   We use direct marketing efforts such as direct mail and telemarketing. These
efforts are used to generate leads and stimulate prospects. Direct marketing
allows us to maintain low selling costs and to offer our customers additional
features or customized services. We employ 21 telesales representatives in our
Memphis call center, and we contract for 11 Spanish speaking telesales
representatives in Convergys' Fort Lauderdale operation.

                                       46
<PAGE>

 E-Commerce

   Our web page provides current information about us, our markets and our
product offerings. We are establishing an online store on our website, located
at www.suncom1.com. The web page conveys our marketing message and we expect it
will generate customers through online purchasing. All information that is
required to make a purchasing decision is available through our website.
Customers are able to choose any of our rate plans, features, handsets and
accessories. The online store will provide a secure environment for
transactions, and customers purchasing through the online store will experience
a similar business process to that of customers purchasing service through
other channels. We expect to add electronic bill viewing and online bill
payment capabilities to our website by year end 1999. Information on our
website is not part of this prospectus.

Customer Care

   We are committed to building strong customer relationships by providing
customers with prompt and helpful service. We serve our customers from our
state of the art facility in Memphis, Tennessee. Convergys, a leading provider
of outsourced call center services, provides back up call center support and
bilingual customer service, for our Spanish speaking customers, from two
facilities in Florida. As of September 30, 1999, the three centers employed 193
customer care representatives including 65 of our employees. The three center
structure allows us to distribute customer service calls between the centers to
promote cost effective 24 hour/seven days a week customer service.

   We have strict quality standards in our care operation, including a
commitment to handling at least 80% of calls within twenty seconds. All of our
centers have sophisticated infrastructure and information systems including
Lucent automated call distributors, Vantive Software, and diagnostic tools for
one call trouble resolution.

   We emphasize proactive and responsive customer service, including welcome
packages and first bill, three months and one year anniversary calls. We also
are expanding web-based services to include online account information to allow
customers to check billing, modify service or otherwise manage their accounts.

   We use a highly selective recruiting process, train our consultants for four
weeks before they take live customer calls, and provide a sophisticated set of
on-line tools for our representatives. Our experience with call forecasting and
our three center design provide us with the resources to serve our customer
base. We believe these initiatives will result in higher levels of customer
satisfaction and reduce customer turnover.

Network Development

   We launched commercial operations in February 1999 and have commenced our
services in each of our major markets. Consistent with our strategy, we
launched in markets which have attractive characteristics for a high volume of
wireless communications usage, including metropolitan "downtown" areas, the
surrounding suburbs, commuting and travel corridors, and popular leisure and
vacation destinations. Immediately upon launch, subscribers had access to
coast-to-coast coverage through roaming arrangements with AT&T and its roaming
partners, both inside and outside our licensed areas. Within each market,
geographic coverage will be based upon changes in wireless communications usage
patterns, demographic changes within our licensed areas and our experiences in
those markets. We currently provide coverage to approximately 65% of the
population of our licensed area. We define coverage to include an entire basic
trading area if we have a significantly developed system in that basic trading
area.

                                       47
<PAGE>

   Construction of our network is scheduled for multiple phases. In the first
half of 1999, we completed the first phase and successfully launched service in
the following 15 markets:

       .  Baton Rouge          .  Lafayette             .  Nantucket
       .  Cape Cod             .  Little Rock           .  Nashua
       .  Concord              .  Martha's Vineyard     .  New Orleans
       .  Fayetteville         .  Manchester            .  San Juan
       .  Hot Springs          .  Memphis               .  Worcester

Our network currently covers a population of 10.7 million. Our subscriber base
and the number of minutes generated on our network have grown rapidly since we
commenced service. Since February 1999, our subscriber base has grown to more
than 100,000 customers.

   We are in the process of completing the second phase, covering ten
additional markets and 1.6 million additional potential customers. To date, we
have launched six of these ten markets, Jackson, Tennessee, Hammond, Louisiana,
Jonesboro, Arkansas, Portsmouth, New Hampshire and Ponce and Arecibo, Puerto
Rico. We expect to complete the second phase by the end of the second quarter
2000. Our network includes five call connection sites and 613 network equipment
sites. We expect that by the end of the second quarter 2000 our network will
cover a total of 25 markets and a population of 12.3 million, and will include
approximately 780 network equipment sites and five connection sites.

   The third and fourth phases of the plan will focus on expanding our coverage
to a total of 46 markets including a population of 3.3 million, and entail
launching service in Beaumont, Alexandria, Evansville, Paducah, Columbia,
Jefferson City, Pine Bluff, Fort Smith, and the Virgin Islands. Upon completion
of the fourth phase, which we expect by the end of 2001, we expect our network
will be available to a population of 15.6 million, and our network will include
8 call connection sites and 1,215 network equipment sites. Additional network
construction will further expand our coverage to all of our markets, except
Monroe.

   In the event we acquire additional licenses, we may modify our network
development plan, and we may need to incur substantial additional debt.

   We are committed to making the capital investment required to develop a
superior network. We intend to invest approximately $55 per covered person for
the construction of our network through 2001, which we believe will ensure
consistent quality performance and result in a high level of customer
satisfaction. Our capital investment is designed to provide a highly reliable
network as measured by performance factors such as percentage of call
completion and number of dropped calls.

   We intend to continue to meet our network development plan by using the
expertise of vendors recognized in the industry for providing high quality
services. Lucent is providing the necessary radio, call connecting and related
equipment for construction of our network. In addition, a number of other
experienced wireless vendors are assisting us in deploying our network.

   We have entered into an agreement with Lucent to purchase up to $285 million
of equipment, software and services for the development of our network. We pay
Lucent for equipment and software at Lucent's list prices less a discount on
the items purchased. Lucent has agreed to provide specified technical support
at no cost, and to provide us with incentive discount bonuses upon our
completing markets. The agreement provides for cooperative marketing of our
services. Lucent has agreed that the prices we pay and payment terms for
equipment, software and services will be no less favorable than those offered
by Lucent to any other affiliate of AT&T Wireless purchasing similar volumes.
We have the right to terminate the agreement at any time subject to paying for
materials already shipped. Lucent may terminate the agreement sixty days
following our material breach. The agreement contains indemnities and
limitations on liabilities for specific damages. Lucent provides us with
warranties on products they produce for specified periods of between 12 and 60
months. Lucent has agreed to provide us with vendor financing. See "Description
of Indebtedness--Vendor Financing."

   The network development requirements imposed by our agreements with AT&T
create significant capital requirements much of which will be covered by
indebtedness we incur. We believe that the capital we have

                                       48
<PAGE>

raised to date as well as the other capital resources currently available to us
under our senior credit facilities, our committed cash equity and the proceeds
of this offering will be sufficient to meet our projected capital requirements
through December 31, 2001. If we acquire additional licenses or properties, we
may need to incur substantial additional debt to complete the acquisition and
construct and operate the acquired properties.

 Network Construction

   As of September 30, 1999, we had leased approximately 735 network equipment
sites and we had built and now operate five sites containing network call
connection sites in four locations. We develop the network design, including
frequency planning for our network equipment sites. We designed our network to
allow us to use existing sites, which minimizes the construction of new towers
and significantly reduces our need to obtain zoning approvals. We use two
experienced vendors, WFI and Divine, to perform property acquisition,
construction and installation of our sites.

Network Operations

   We maintain a state-of-the-art network operations center and, to ensure
continuous monitoring and maintenance of our network, we have a disaster
recovery plan. The effective operation of our network requires:

  .  connection agreements and agreements to transmit signals from network
     equipment sites to call connection equipment with other communications
     providers;

  .  long distance connection;

  .  the implementation of roaming arrangements;

  .  the development of network monitoring systems; and

  .  the implementation of information technology systems.

 Connection

   Our network is connected to the public telephone network to facilitate the
origination and termination of traffic between our network and both the local
and long distance carriers. We have signed agreements with numerous carriers,
including, among others:

  .  BellSouth in New Orleans and Memphis;

  .  SBC Communications in Little Rock;

  .  Bell Atlantic in New England; and

  .  Puerto Rico Telephone in Puerto Rico.

   These agreements are standard agreements entered into with all qualifying
carriers on generally the same terms. Each party pays the other for the
carrying or completion of calls on the other's network.

 Long Distance

   We have executed a wholesale long distance agreement with AT&T providing for
preferred rates for long distance services. See "Certain Relationships and
Related Transactions--AT&T Agreements."

 Roaming

   Through our arrangements with AT&T and via the use of advanced handsets, our
customers have roaming capabilities on AT&T's wireless network and AT&T's
customers have roaming capability on our wireless network. Further, we have the
benefit of AT&T's roaming agreements with third party carriers at AT&T's
preferred pricing. These agreements, together with AT&T's wireless network,
cover approximately 98% of the U.S. population, including in-region roaming
agreements covering all of our launched service areas. AT&T has recently
experienced significant growth in roaming traffic in our markets as a result of
the success of the AT&T Digital One Rate SM plan.

                                       49

 Network Monitoring Systems

   Our network operations center provides around-the-clock monitoring and
maintenance of our entire network. The network operations center is equipped
with sophisticated electronics that constantly monitor the status of all
network equipment sites and call connection equipment and record network
traffic. The network operations center provides continuous monitoring of system
quality for blocked or dropped calls, call clarity and evidence of tampering,
cloning or fraud. We designed our network operations center to oversee the
interface between customer usage, data collected by call connection equipment
and our billing systems. Our network operations center is located in the
Memphis site containing call connection equipment, and we also have back-up
network operations center capabilities in our Arlington, Virginia data center.

 Information Technology

   We operate management information systems to handle customer care, billing,
network management and financial and administrative services. The systems focus
on three primary areas:

  .  network management, including service activation, pre-pay systems,
     traffic and usage monitoring, trouble management and operational support
     systems;

  .  customer care, including billing systems and customer service and
     support systems; and

  .  business systems, including financial, purchasing, human resources and
     other administrative systems.

   We have incorporated sophisticated network management and operations support
systems to facilitate network fault detection, correction and management,
performance and usage monitoring and security. System capabilities have been
developed to allow over-the-air activation of handsets and implement fraud
protection measures. We maintain stringent controls for both voluntary and
involuntary deactivations. Subscriber disconnections initiated by us are
minimized by:

  .  preactivation screening to identify any prior fraudulent or bad debt
     activity;

  .  credit review; and

  .  call pattern profiling to identify where activation and termination
     policy adjustments are needed.

   We entered into a long-term software license, development and implementation
agreement with LHS Communications Systems and CAP Gemini America to support our
established billing system, and we have engaged a variety of industry leaders
such as Lucent and Lightbridge to provide activation, fraud management and
support systems.

Technology

 TDMA Digital Technology

   We have chosen digital TDMA technology for our network. TDMA technology
allows for:

  .  the use of advanced handsets which allow for roaming across the PCS and
     cellular portion of the airwaves, including both analog and digital
     technologies;

  .  enhanced services and features, such as short-messaging, extended
     battery life, added call security and improved voice quality; and

  .  network equipment sites that are small and that improve network coverage
     with low incremental investment.

   TDMA technology is the digital technology choice of two of the largest
wireless communications companies in the United States, AT&T and SBC
Communications. This technology served an estimated 19 million subscribers
worldwide and nine million subscribers in North America as of December 31,
1998, according to the Universal Wireless Communications Consortium, an
association of TDMA providers and manufacturers. We believe that the increased
volume of TDMA has increased the probability that this technology will remain
an industry standard. TDMA equipment is available from leading
telecommunication vendors such as Lucent, Ericsson and Northern Telecom, Inc.

                                       50
<PAGE>

 Future Technology Development

   Our advanced TDMA technology provides us the ability to offer new services,
including information services, wireless service applications inside buildings,
two-way text messaging, voice-activated dialing, audio e-mail retrieval and web
browsing. In addition, TDMA technology provides us with a strong foundation for
the introduction of high-speed wireless data.

   The mobile data market is projected to grow at 30% annually over the next
seven years, leading to a vast array of new services. Today, we participate in
the data market through our short message service, one-way paging broadcasts,
and Internet e-mails sent to our mobile phones. These applications are provided
through the signaling capabilities of TDMA. We expect to introduce a suite of
information services, including news, sports, stock quotes and weather, in
January 2000. Our next series of offerings are scheduled for the second quarter
of 2000, using two-way short message service and handsets capable of accessing
the Internet.

   Our planned evolution to higher speed data applications, including video
conferencing, is through the implementation of enhanced data rates for global
evolution, which is expected to be available in 2001. With our TDMA
architecture, we expect to be able to support faster transmission speeds with
limited software and hardware upgrades. We are working with AT&T to plan for an
evolution to these third generation services in 2002, and with Lucent to
understand the implications on our network development.

Competition

   We believe subscribers choose a wireless communications service provider
principally based upon network coverage, pricing, quality of service and
customer care.

   We compete directly with at least two cellular providers and other PCS
providers in each of our markets and against enhanced special mobile radio
operations in some of our markets. We compete with at least one analog, one
CDMA and one GSM operator in each of our markets other than Puerto Rico and New
Orleans where there is no GSM system currently in operation. Most of the
existing cellular providers in our markets have an infrastructure in place and
have been operational for a number of years, with some of these competitors
having greater financial and technical resources than we do. These cellular
operators may upgrade their networks to provide services comparable to those
offered by us. We also compete with other PCS license holders in each of our
markets:

  .  in New Orleans, we compete primarily against Radiofone and BellSouth for
     cellular services, Sprint PCS and PrimeCo Personal Communications for
     PCS, and Nextel for enhanced special mobile radio;

  .  in Memphis, we compete primarily against GTE and BellSouth for cellular
     services, Powertel and Sprint PCS for PCS and Nextel for enhanced
     special mobile radio;

  .  in Little Rock, we compete primarily against ALLTEL and SBC
     Communications for cellular services and Sprint PCS for PCS;

  .  in New England, we compete primarily against SBC Communications and Bell
     Atlantic for cellular services and Sprint PCS, Omnipoint Technologies
     for PCS and Nextel for enhanced special mobile radio;

  .  in Puerto Rico, we compete primarily against Puerto Rico Telephone
     Company and Cellular One for cellular services and Centennial Cellular
     and NewCom Wireless Services, Inc. for PCS.

   We also compete with resellers of wireless communications services in each
of our markets. Resellers purchase large volumes of services on a wireless
operator's network, usually at a discount, and resell the services to end users
under the reseller's own brand name. While the network operator receives some
revenue from the sale of services to the reseller, the operator is competing
with its own customer for sales to the end users. The principal resellers in
our markets include MCI in New England and Motorola in Puerto Rico. We have
agreed to resell services to AT&T in each of our markets should AT&T desire to
do so. We have not yet entered into any such arrangements with AT&T or any
other party. The FCC informally limits the amount of our minutes AT&T can
resell in our market to less than a majority of the minutes they sell in our
market. If we allow AT&T to resell more than a majority of our minutes, the FCC
may question our compliance with FCC license requirements.

                                       51
<PAGE>

   As the most recent entrant into the market for wireless communications
services, we do not believe that we have obtained a significant share of the
market in any of our areas of operation. As a recent entrant, we face
significant competition from operators who have already established strong
market positions and have signed up many customers. Most of the existing
cellular operators have developed systems that have larger local and regional
coverage than we currently have or anticipate developing. We seek to compete by
offering a competitive product with attractive pricing plans and through our
extensive access to roaming, including in-region roaming, which gives us an
effective coverage area competitive with that of our principal competitors. We
have developed our pricing plans to be competitive and to emphasize the
advantages of our offerings. We have and may continue to discount our pricing
in order to obtain customers or in response to downward pricing in the market
for wireless communications services.

   We do not believe that we are at a significant competitive disadvantage to
competitors that can market wireless communications services together with
other services, such as traditional telephone service, cable television access
or Internet access. We may face such disadvantages in the future as a result of
modified offerings by our competitors or changes in consumer expectations if
such bundled offerings become common. If we were to become disadvantaged, we
would be forced to respond by modifying our pricing or seeking to offer
competitive bundled services. We may not be able to do so on profitable terms.

   Our ability to compete successfully will depend, in part, upon our ability
to anticipate and respond to various competitive factors affecting the
industry, including the introduction of new services, changes in consumer
preferences, demographic trends, economic conditions and competitors' discount
pricing strategies, all of which could adversely affect our operating margins.
We expect that once deployed, our extensive digital network will provide cost-
effective means to react appropriately to any price competition. Additionally,
we believe we have invested in network and information technology which
provides us scaleable cost effective capabilities to combat competition.

Government Regulation

   We are subject to substantial regulation by the FCC, state public utility
commissions and, in some cases, local authorities. Our principal operations are
classified as commercial mobile radio service by the FCC, subject to regulation
under Title II of the Communications Act of 1934, as amended by the
Telecommunications Act of 1996, as a common carrier and subject to regulation
under Title III of the Communications Act as a radio licensee. The states are
preempted from regulating our entry into and rates for commercial mobile radio
service offerings, but remain free to regulate other terms and conditions of
our commercial mobile radio service services and to regulate other intrastate
offerings by us. Congress and the states regularly enact legislation, and the
FCC, state commissions and local authorities regularly conduct rulemaking and
adjudicatory proceedings that could have a material adverse effect on us and
other similarly situated carriers. In addition, our nature as a regulated
entity may adversely affect our ability to engage in, or rapidly complete,
transactions and may require us to expend additional resources in due diligence
and filings related to FCC and other requirements, as compared to unregulated
entities.

 FCC Common Carrier Regulation Under Title II

   Under Title II of the Communications Act, among other things, we are:

  .  required to offer service upon reasonable request;

  .  prohibited from imposing unjust or unreasonable rates, terms or
     conditions of service;

  .  proscribed from unjustly or unreasonably discriminating among customers;

  .  required to reserve communications capacity for law enforcement
     surveillance operations and to make technical network changes to
     facilitate this surveillance;

  .  required to make our services and products accessible to, and usable by,
     Americans with disabilities, if readily achievable; and

                                       52
<PAGE>

  .  required to comply with limitations on our use of customer proprietary
     network information.

   Under the Telecommunications Act, we are entitled to benefits when
negotiating interconnection arrangements with other communications carriers,
such as resale rights, our customers being able to keep their old numbers when
switching to us and compensation equal to that of the carriers, but we are
subject to those same requirements when other carriers seek to interconnect
with our network. The FCC is still in the process of implementing some of these
benefits. While the rates of common carriers are subject to the FCC's
jurisdiction, the FCC forbears from requiring commercial mobile radio service
carriers to file tariffs for their services. Common carriers, including
commercial mobile radio service providers, are also prohibited under the
Communications Act from unreasonably restricting the resale of their services
and are required to offer unrestricted resale. There can be no assurance that
the FCC will not choose to regulate common carriers more comprehensively to
promote competition under the Telecommunications Act, which could have an
adverse effect on our operations.

 FCC Radio License Regulation Under Title III

   Among other things, Title III of the Communications Act:

  .  does not permit licenses to be granted or held by entities that have
     been subject to the denial of federal benefits;

  .  requires us to seek prior approval from the FCC to transfer control of
     us or to assign our radio authorizations, including subdividing our
     radio airwaves or partitioning geographic license areas, except in very
     limited circumstances; and

  .  limits foreign ownership in radio licensees, including PCS providers.

   While we believe that we comply with Title III, any future violation of
these limitations could result in license revocation, forfeiture or the forced
restructuring of our ownership to comply with the rules, any of which could
have a material adverse effect on us. The Title III restrictions could also
materially adversely affect our ability to attract additional equity financing.

 FCC Commercial Mobile Radio Service Regulation

   The FCC rules and policies impose substantial regulations on commercial
mobile radio service providers. Among other regulations, commercial mobile
radio service providers such as us:

  .  incur costs as a result of required contributions to federal programs;

  .  are prohibited from acquiring or holding an attributable interest in
     PCS, cellular or special mobile radio licenses with more than 45MHz of
     airwaves in the same metropolitan area, and more than 55 MHz in rural
     markets;

  .  are required to provide manual roaming service to enable a customer of
     one provider to obtain service while roaming in another carrier's
     service area;

  .  are required to route emergency calls to public safety centers and
     provide the public safety centers with information regarding the
     originating number and the location of the caller; and

  .  will be required to allow subscribers to retain their telephone numbers
     when changing service providers after March 31, 2000, in some
     circumstances.

   While we believe we comply with these regulations, any violation of the
commercial mobile radio service regulations could result in a revocation or
forfeiture of our licenses that would have a material adverse effect on us. In
addition, there can be no assurance that the FCC will not choose to regulate
commercial mobile radio service providers more comprehensively, which could
have an adverse effect on our operations.

                                       53
<PAGE>

 FCC Personal Communications Services Regulation

   We are subject to service-specific regulations under the FCC's rules. Among
other things, these regulations provide that PCS licensees, such as us, are
granted licenses for a 10-year term, subject to renewal. Under these policies,
we will be granted a renewal expectancy that would preclude the FCC from
considering competing applications if we have:

  .  provided "substantial" performance, that is "sound, favorable and
     substantially above a level of mediocre service just minimally
     justifying renewal;" and

  .  substantially complied with FCC rules and policies and the
     Communications Act.

   While we intend to structure our operations to secure a renewal expectancy,
there can be no assurance that a renewal expectancy will be granted and, if the
renewal expectancy is not granted, that our licenses will be renewed. Our
failure to obtain renewal of our licenses would have a material adverse effect
on our operations.

   These regulations also govern the transmission characteristics of PCS
handsets and network equipment sites and other technical requirements. PCS
licensees are required to comply with limits intended to ensure that these
operations do not interfere with radio services in other markets or in other
portions of the airwaves and to ensure emissions from mobile transmitters do
not cause adverse health effects. We are also subject to minimum construction
requirements that will require us to deploy facilities with service coverage of
a particular amount of the population of our licensed area within specified
time periods. While we believe we comply with all PCS regulations in effect,
any violation of the PCS regulations could result in a revocation or forfeiture
that would have a material adverse effect on us. In addition, there can be no
assurance that the FCC will not choose to regulate PCS licensees more
comprehensively, which could have an adverse effect on our operations.

 Relocation of Fixed Microwave Licensees

   Because PCS carriers use airwaves occupied by existing microwave licensees,
the FCC has adopted special regulations governing the relocation of incumbent
systems and cost-sharing among licensees that pay to relocate microwave
incumbents. Relocation usually requires a PCS operator to compensate an
incumbent for the costs of system modifications and new equipment required to
move the incumbent to new portions of the airwaves, including possible premium
costs for early relocation to alternate portions of the airwaves. The
transition plan allows most microwave users to operate in the PCS portion of
the airwaves for a one-year voluntary negotiation period and an additional one-
year mandatory negotiation period following the issuance of the PCS license.
These periods are longer for public safety entities. We have entered into all
necessary agreements for microwave relocation. Relocated licensees may exercise
their rights to move back to their original sites in the event the new sites
are inadequate. Any delay in the relocation of microwave users to other
portions of the airwaves also may affect adversely our ability to operate our
network. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

 FCC and Federal Aviation Administration Facilities Regulation

   Because we acquire and operate antenna sites for use in our network, we are
subject to FCC and Federal Aviation Administration regulations governing
registration of towers, the marking and lighting of structures and regulations
governing compliance with the National Environmental Policy Act of 1969, which
requires carriers to assess the impact of their operations on the environment,
including the health effects of radio airwave radiation on humans.

 FCC Designated Entity and Small Business Regulation

   Each of TeleCorp Holding, TeleCorp LMDS and Viper Wireless was the winning
bidder of licenses in the auction of PCS licenses. Viper Wireless also acquired
six licenses in the recent designated entity PCS reauction.

                                       54
<PAGE>

With respect to those licenses granted by the FCC, and additional designated
entity licenses acquired and to be acquired through auctions and later
transactions, we:

  (1) believe we qualify as a very small business and as an entrepreneurs,
      and

  (2) intend to diligently pursue and maintain our qualification as a very
      small business and as an entrepreneur in a manner intended to ensure
      compliance with the applicable FCC rules.

   We rely on representations of our investors to determine our compliance with
the FCC's rules applicable to PCS licenses. There can be no assurance, however,
that our investors or we will continue to satisfy these requirements during the
term of any PCS license granted to TeleCorp Holding or TeleCorp PCS, LLC, our
wholly owned subsidiary, or that we will be able successfully to implement
divestiture or other mechanisms included in our corporate charter that are
designed to ensure compliance with FCC rules. Any non-compliance with the FCC
very small business and entrepreneur rules could subject us to penalties,
including a fine, revocation of our PCS licenses, acceleration of installment
payment obligations or retroactive loss of bidding credits.

   Entrepreneurs.  In order to hold some of our PCS licenses, the qualifying
entity, an entrepreneur, and its affiliates must have had less than $125
million in average gross revenues in the last two years and less than $500
million in total assets at the time it filed its application to acquire the
licenses. In calculating revenues and assets for these purposes, the FCC
includes the gross revenues and total assets of our affiliates, those entities
that hold attributable interests in us and the affiliates of the entities.
However, the revenues and assets of affiliates are not attributable to the
licensee if the licensee maintains an organizational structure that satisfies
entrepreneur requirements. For at least five years after the initial licensing
of a these licenses, a licensee must continue to meet the control group
requirements to continue to qualify for the installment payment program and
must continue to meet the very small business requirements to continue to
qualify for the bidding credits received in the auction, although normal
business growth as a result of holding the licenses will not disqualify a
licensee.

   Very Small Business.  We are also structured under the FCC's rules to
qualify as a very small business. A very small business is an entity that,
together with its affiliates and entities that hold interests in the applicant
and their affiliates, has average annual gross revenues of not more than $15
million for the previous three calendar years. As a result of our
classification as a very small business, we were eligible for both a 25%
bidding credit and for a preferential installment payment program. In the more
recent reauction, Viper Wireless qualified as a very small business, eligible
for the same bidding credit, but the FCC has ceased to provide installment
payment financing.

   Control Group Requirements.  To avoid attribution of the revenues and assets
of some of our investors, we are required to maintain a conforming control
group and to limit the amount of equity held by these entities on a fully-
diluted basis. These requirements mandate that the control group, among other
things, have and maintain both actual and legal control of the licensee. Under
these control group requirements:

  .  an established group of investors meeting the financial qualifications
     must own at least three-fifths of the control group's equity, or 15% of
     the licensee's overall equity, on a fully-diluted basis and at least
     50.1% of the voting power, in the licensee entity; and

  .  additional members of the control group must hold, on a fully-diluted
     basis, the remaining 10% equity interest in the licensee entity.

   Additional members may be non-controlling institutional investors, including
most venture capital firms. A licensee must have met the requirements at the
time it filed its application to acquire these licenses and must

                                       55
<PAGE>

continue to meet the requirements for five years following the date that a
license is granted, although normal business growth is permitted. Beginning the
fourth year of the license term, the FCC rules:

  .  eliminate the requirement that additional members hold the 10% equity
     interest; and

  .  allow the qualifying investors to reduce the minimum required equity
     interest from 15% to 10%.

   If the FCC were to determine that we did not comply with the regulations, we
would be required to attribute the revenues of additional stockholders, which
would likely cause the loss of our status both as an entrepreneur and a very
small business. Loss of this status would have a materially adverse effect on
us.

   FCC Transfer Restrictions.  During the first five years of their license
terms, some PCS licensees may only transfer or assign their license, in whole
or in part, to other qualified entrepreneurs. The acquiring entities would take
over the license, or any portion of the license, subject to separately
established installment payment obligations. After five years, licenses are
transferable to entrepreneurs and non-entrepreneurs alike, subject to unjust
enrichment penalties. If transfer occurs during years six through ten of the
initial license term to a company that does not qualify for the same level of
auction preferences as the transferor, the sale would be subject to immediate
payment of the outstanding balance of the government installment payment debt
and payment of any unjust enrichment assessments as a condition of transfer.
The FCC has also initiated transfer disclosure regulations that require
licensees who transfer control of or assign a PCS license within the first
three years to file associated contracts for sale, option agreements,
management agreements or other documents disclosing the total consideration
that the applicant would receive in return for the transfer or assignment of
its license. If the FCC determines that a transferor or assignor is being
unjustly enriched by a proposed sale or transfer of a license, it may condition
its approval of the transaction on payment of money to the U.S. Treasury,
accelerate installment payments or require repayment of bidding credits.

 State and Local Regulation

   The FCC permits the states to:

  .  regulate terms and conditions of our commercial mobile radio service
     services other than rates and entry and may regulate all aspects of our
     intrastate toll services;

  .  regulate the intrastate portion of services offered by local telephone
     carriers, and therefore the rates we must pay to acquire critical
     facilities from other common carriers;

  .  administer numbering resources, subject to federal oversight; and

  .  have other responsibilities that impact the nature and profitability of
     our operations, including the ability to specify cost-recovery
     mechanisms for network modifications to support emergency public safety
     services.

   States and localities also regulate construction of new antenna site
facilities and are responsible for zoning and developmental regulations that
can materially impact our timely acquisition of sites critical to our radio
network. The states and localities regularly conduct legislative, rulemaking
and adjudicatory proceedings on matters within their jurisdiction that could
have a material adverse effect on us and other similarly situated carriers.
States may petition the FCC to expand their jurisdiction over commercial mobile
radio service rates and entry. There can be no assurance that a state in which
we operate will not attempt to engage in more comprehensive regulation of our
operations, which could increase the costs of providing service and materially
affect our ability to operate in that state.

 Emission and Hands-Free Regulation

   Media reports have suggested that some radio airwave emissions from wireless
handsets may be linked to health concerns, including the incidence of cancer.
Data gathered in studies performed by manufacturers of wireless communications
equipment dispute these media reports. Further, a major industry trade
association and governmental agencies have stated publicly that the use of
wireless handsets does not pose any undue health

                                       56
<PAGE>

risks. Nevertheless, concerns regarding radio airwave emissions could have the
effect of discouraging the use of wireless handsets, which would decrease
demand for our services.

   The FCC adopted rules specifying the methods to be used in evaluating radio
airwave emissions from radio equipment, including wireless handsets. The hand-
held digital telephones that we offer to our customers comply with the
standards adopted under the new rules. These handsets may not comply with any
rules adopted by the FCC in the future. The failure of these handsets to
remain in compliance with applicable FCC rules and standards would decrease
demand for our services.

   Recent studies have shown that hand-held digital telephones interfere with
medical devices, including hearing aids and pacemakers. The University of
Oklahoma Center for the Study of Wireless Electromagnetic Compatibility,
together with industry trade associations and other interested parties, are
currently studying the extent of, and possible solutions to, this
interference. If these studies demonstrate significant interference or create
public concern about interference, the results of these studies could decrease
demand for our services.

   Measures that would:

  .  require hands free use of cellular phones while operating motor
     vehicles;

  .  ban cellular phone use while driving;

  .  limit the length of calls while driving; or

  .  require people to pull to the side of the road to use cellular phones
     while driving,

have been proposed or are being considered in 12 state legislatures. In
addition, some gas stations have banned the use of mobile phones on their
premises. We cannot predict the success of the proposed laws concerning car
phone use or the effect on the use of cellular phones as a result of the
publicity surrounding or passage of these laws. In addition, more restrictive
measures or measures aimed at wireless services companies as opposed to users
may be proposed or passed in state legislatures in the future. The passage or
proliferation of this legislation could decrease demand for our services.

Intellectual Property

   The AT&T and globe design logo is a service mark registered with the U.S.
Patent and Trademark Office. AT&T owns the service mark. We use the AT&T and
globe design logo, on a royalty free basis, with equal emphasis on our SunCom
brand and logo, solely within our licensed area in connection with marketing,
offering and providing licensed services to end-users and resellers of our
services. Our license agreement with AT&T grants us the right and license to
use licensed marks on permitted mobile phones. This license agreement contains
numerous restrictions with respect to the use and modification of licensed
marks. See "Certain Relationships and Related Transactions--AT&T Agreements."

   We, Triton PCS and Tritel Communications have adopted a common brand,
SunCom, that is co-branded with equal emphasis with the AT&T brand name and
logo. Each of the SunCom companies owns one-third of Affiliate License Co.,
which owns the SunCom name. We and the other SunCom companies license the
SunCom name from Affiliate License Co. We use the brand to market, offer and
provide services to end-users and resellers of our PCS. See "--Marketing
Strategy," "Certain Relationships and Related Transactions--Other Related
Party Transactions."

Employees

   As of September 30, 1999, we employed approximately 793 people. None of our
employees currently are represented by a union. We believe that our relations
with our employees are good.

                                      57

Properties

   We lease space for our call connection equipment in New Orleans, Boston and
Puerto Rico and for our network operations center, our call connection
equipment, our customer care and our data center in Memphis. Further, we have
operating leases primarily related to our headquarters, regional offices,
retail store locations, distribution outlets, office space and network
equipment sites.

Legal Proceedings

   We are not a party to any lawsuit or proceeding which is likely, in the
opinion of management, to have a material adverse effect on our financial
position, results of operations and cash flows. We are a party to routine
filings and customary regulatory proceedings with the FCC relating to our
operations.

some bonuses are specified in employment agreements. The bonuses earned in 1997
were paid in 1998 and are not included in this table. The bonuses in the table
were earned in 1998 and were paid in 1999. Other annual compensation consists
of amounts reimbursed for relocation expenses and any taxes that we paid on
behalf of the executive for the reimbursement.

1998 Restricted Stock Plan

   In July 1998 we established the TeleCorp PCS, Inc. 1998 Restricted Stock
Plan to award key employees shares of our series E preferred stock and class A
common stock. Each award is subject to a five- or six-year vesting schedule
that depends on the employee's date of hire, with unvested shares being
redeemed by us for $.003 per share upon termination of employment. The shares
granted are subject to the same transfer restrictions and repurchase rights as
our shares held by AT&T and our other initial investors. See "Description of
Capital Stock." As of September 30, 1999, 6,760 shares of series E preferred
stock and 3,846,196 shares of class A common stock are outstanding under this
plan. We repurchased an additional 1,361 shares of series E preferred stock and
959,260 shares of class A common stock from our stockholders, which we had
granted under this plan, and we have regranted all of these repurchased shares
under this plan.

1999 Stock Option Plan

   On July 22, 1999, we implemented the 1999 Stock Option Plan to award
employees and members of our board options to acquire shares of our class A
common stock. Our board has the discretion to determine the terms of any
options granted under this plan. We have reserved 1,814,321 shares of our class
A common stock for issuance under this plan. On July 22, 1999, our board
approved the grant of options to virtually all our employees and three of our
directors to purchase 552,505 shares of class A common stock under our plan at
an exercise price of $.0065 per share, the estimated fair value of the class A
common stock on the date of grant. We effected these grants on August 31, 1999.
These options vest ratably over a three to four year period. Upon the closing
of the offering, the option holders will be able to exercise any vested
options.

Management Agreement

   Under a management agreement dated July 17, 1998, as amended, TeleCorp
Management, under our oversight, review and ultimate control and approval,
assists us with:

  .  administrative services, such as accounting, payment of all bills and
     collection;

  .  operational services, such as engineering, maintenance and construction;

  .  marketing services, such as sales, advertising and promotion;

  .  regulatory services, such as tax compliance, FCC applications and
     regulatory filings; and

  .  general business services, such as supervising employees, budgeting and
     negotiating contracts.

   Mr. Vento and Mr. Sullivan own TeleCorp Management.

   TeleCorp Management has agreed to provide the services of Mr. Vento and Mr.
Sullivan in connection with the performance of TeleCorp Management's
obligations under the management agreement. Mr. Vento and Mr. Sullivan have
agreed to devote their entire business time and attention to providing these
services, provided that they may devote reasonable periods of time to other
enumerated activities.

   We reimburse TeleCorp Management for all out of pocket expenses it incurs
for the retention of third parties on our behalf. We pay TeleCorp Management
fees of $550,000 per year, payable in monthly installments. TeleCorp Management
is also entitled to a potential annual bonus based upon the achievement of
objectives established by the compensation committee of our board for a
particular calendar year. In 1998, we paid bonuses totaling approximately
$285,000 to TeleCorp Management.

   The management agreement has a five-year term. We may terminate the
management agreement immediately in certain circumstances including:

  .  indictment of Mr. Vento or Mr. Sullivan for a felony;

  .  a material breach which remains uncured after 30 days written notice;

  .  the failure of TeleCorp Management to provide to us the services of Mr.
     Vento and Mr. Sullivan;

  .  an event of default on any of our credit agreements for borrowings of
     $25.0 million or more; or

  .  acceleration of any of our indebtedness over $25.0 million.

   TeleCorp Management may terminate the agreement voluntarily upon 30 days
written notice to us. TeleCorp Management may also terminate the agreement
immediately if:

  .  Mr. Vento and Mr. Sullivan are removed as directors or are demoted or
     removed from their respective offices or there is a material
     diminishment of Mr. Vento's and Mr. Sullivan's responsibilities, duties
     or status, which diminishment is not rescinded within 30 days after the
     date of receipt by our board from Mr. Vento and Mr. Sullivan of their
     respective written notice referring to the management agreement and
     describing the diminishment; or

  .  we relocate our principal offices without TeleCorp Management's consent
     to a location more than 50 miles from our principal offices in
     Arlington, Virginia.

   If TeleCorp Management terminates the agreement for the two preceeding
reasons or if we terminate the agreement because of a breach by TeleCorp
Management or we fail to comply with any of our credit agreements for borrowed
money in the amount of $25.0 million or more, TeleCorp Management will be
entitled to their management fee and annual bonus. Their annual bonus will be
determined as follows:

  .  if the date of termination is on or prior to June 30 or any applicable
     calendar year, the annual bonus will be equal to a pro rata portion of
     the annual bonus in respect of that year, as determined based upon our
     achievement of the objectives for that year;

                                       65
<PAGE>

  .  if the date of termination is after June 30 of any applicable calendar
     year, the annual bonus will be equal to the annual bonus payable in
     respect of that year, as determined based upon our achievement of the
     objectives for that year,

in either instance payable upon the later to occur of 30 days after
certification of our financial statements for that year and the last day of the
month after which a new management service provider is retained by us, and
conditioned upon TeleCorp Management having nominated a successor person or
persons, who are acceptable to our board, and:

  .  who would not cause a significant and detrimental effect on our
     eligibility to hold our PCS licenses and to realize the benefits, if
     any, that we derive from TeleCorp Management's status as a very small
     business; and

  .  to whom our voting preference common stock and class C common stock will
     be transferred by Mr. Vento and Mr. Sullivan.

   The management agreement protects us if TeleCorp Management does not
nominate an acceptable person or persons to provide management services to us.

   The shares of class A common stock and series E preferred stock that Mr.
Vento and Mr. Sullivan received under the securities purchase agreement vest in
accordance with the following schedule, which is contained in the management
agreement:

       July 17, 2003..........................................         15%
</TABLE>

   The remaining shares vest according to the completion of different steps in
our minimum construction plan.

   We are obligated to repurchase from Mr. Vento and Mr. Sullivan, and they are
required to sell to us, following the termination of the management agreement
for any reason, the amount of our class A common stock, up to 5,764,704 shares,
and our series E preferred stock, up to 18,219 shares, that have not yet
vested.

   During the term of the management agreement, and under limited circumstances
for a period following termination, TeleCorp Management, Mr. Vento and Mr.
Sullivan are prohibited from assisting or becoming associated with any person
or entity, other than as a holder of up to 5% of the outstanding voting shares
of any publicly traded company, that is actively engaged in the business of
providing mobile wireless communications services in our territory, and from
employing any person who was employed by us unless that person was not employed
by us for a period of at least six months.

Employee Agreement

   On July 17, 1998, we entered into an employee agreement with Ms. Dobson,
under which she serves as our Chief Operating Officer at a base annual salary
of $250,000. Ms. Dobson is eligible under the employee agreement, at our
board's discretion, to receive a potential annual bonus based upon the
achievement of objectives established by the compensation committee of our
board.

   Ms. Dobson's employee agreement provides that she is an employee-at-will. We
will reimburse the reasonable expenses that she incurs while performing her
services under her employee agreement and she may participate in our employee
benefit plans available to employees of comparable status and position.


                                       66
<PAGE>

   If Ms. Dobson should die, we will pay any amounts that we owe her under her
employee agreement accrued prior to her death to her estate, heirs and
beneficiaries. All family medical benefits under the employee agreement for the
benefit of Ms. Dobson will continue for six months after death. Termination for
cause is:

  .  engaging in misconduct which has caused demonstrable and serious injury,
     financial or otherwise, to us or our reputation;

  .  being convicted of a felony or misdemeanor as evidenced by a judgment,
     order or decree of a court of competent jurisdiction;

  .  failing to comply with our board's directions, or neglecting or refusing
     to perform the executive's duties or responsibilities, unless changed
     significantly without the executive's consent; or

  .  violating the employee agreement or restricted stock grant plan.

   If we terminate Ms. Dobson for cause, or she voluntarily quits, we will pay
her any amounts that we owe her accrued prior to the cessation of employment.
If we terminate her other than for cause, we will pay Ms. Dobson an amount
equal to her then annual base salary, at normal payroll intervals, as well as
continue to cover her under our employee benefit plans for 12 months.

   Under her employee agreement, Ms. Dobson is subject to confidentiality
provisions, and has agreed, for one year after cessation of employment with us,
to non-competition and non-solicitation provisions and to limit public
statements concerning us.

Separation Agreement

   On March 8, 1999, we entered into a separation agreement with Mr. Dowski,
under which we agreed to pay Mr. Dowski:

  .  $17,500 per month for 12 months;

  .  a lump sum of $105,000, representing a 1998 bonus;

  .  a lump sum equal to earned but unpaid or unused vacation;

  .  $4,300 as reimbursement for relocation expenses, including taxes payable
     by Mr. Dowski on the sum; and

  .  a lump sum equal to outstanding travel and expense reimbursement.

   We also agreed to continue covering Mr. Dowski under our employee benefit
plans for 12 months.

   In addition, we repurchased 577 shares of Mr. Dowski's series E preferred
stock and 406,786 of Mr. Dowski's shares of class A common stock for an
aggregate amount of approximately $19 in accordance with his share grant
agreement concerning such restricted stock.

   The separation agreement contained mutual releases by Mr. Dowski and us of
each other. In addition, in the separation agreement, Mr. Dowski confirmed his
confidentiality agreements with us, and his one-year non-competition, non-
solicitation and limitation on public speaking agreements.

         PRINCIPAL STOCKHOLDERS AND BENEFICIAL OWNERSHIP OF MANAGEMENT

   The following table describes, as of September 30, 1999, the number of
shares of each class of our voting stock beneficially owned prior to and
following this offering and the concurrent offering to AT&T Wireless by:

    .  each of our directors;

    .  executive officers named in the summary compensation table above,

    .  each person known by us to beneficially own more than 5% of the
       outstanding shares of any class of our voting capital stock at such
       date, and

    .  all of our current directors and executive officers, as a group.

Except as otherwise indicated, the address for each director and executive
officer is c/o TeleCorp, 1010 N. Glebe Road, Suite 800, Arlington, Virginia
22201.

   The following table shows the beneficial ownership of our class A common
stock on the assumption that FCC restrictions on the conversion of some classes
of our capital stock into class A common stock no longer apply to us and any
required stockholder approvals have been obtained.

   Under the terms of our restated certificate of incorporation that will
become effective upon completion of this offering, until the occurrence of
defined events, and subject to specific rights granted to holders of other
classes of our capital stock, Mr. Vento and Mr. Sullivan, as the holders of
voting preference common stock, possess 50.1% of the voting power of all shares
of our capital stock, and the holders of class A common stock possess 49.9% of
the voting power of all shares of our capital stock. If, under circumstances
described under "Description of Capital Stock," we receive FCC approval for the
class A common stock and voting preference common stock to vote as a single
class, the class A common stock and the voting preference common stock will
vote as a single class on all matters and be granted one vote per outstanding
share. Holders of some of our other classes of capital stock have been granted
voting rights regarding matters specifically affecting those classes. Finally,
our initial investors beneficially holding a majority in interest of our common
stock have the right to nominate two members of our board and, so long as AT&T
continues to own not less than two-thirds of the shares of series A preferred
stock it owned on July 17, 1998, it will have the right to nominate one member
of our board.

*  Less than one percent.
(a)  Pursuant to SEC rules, percentages of beneficial ownership of the class A
     common stock are calculated assuming that shares of class A common stock
     issuable upon conversion of securities convertible into class A common
     stock are outstanding for purposes of each respective stockholder or
     group, but not outstanding for purposes of computing the percentage of any
     other person. Included in the calculation of beneficial ownership are
     shares of class A common stock issuable upon conversion or exercise of
     securities within 60 days of September 30, 1999 and conversion of our
     class C, class D and voting preference common stock upon lapse of FCC
     ownership restrictions.
(b)  Mr. Vento and Mr. Sullivan each own 1,545 shares of voting preference
     stock. Together, the voting preference stock possesses 50.1% of the voting
     power of all shares of our capital stock. Mr. Vento and Mr. Sullivan are
     required to vote their shares of voting preference stock together on all
     matters. The total voting power assumes conversion of all of our
     outstanding series F preferred stock, class C and class D common stock and
     the issuance of 552,505 shares issuable under outstanding options, subject
     in some cases to vesting. Percentage of total voting power is calculated
     on a fully-diluted basis assuming in all cases for all persons exercise of
     outstanding options and conversion of series F preferred stock and class C
     and class D common stock into shares of class A common stock.
(c) Consists of 352,956 shares of class A common stock, 575 shares of class C
    common stock and 3,780 shares of class D common stock held by TeleCorp
    Investment Corp., LLC., of which CB Capital Investors, L.P. owns a majority

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

AT&T Agreements

   On January 23, 1998, we and AT&T announced the formation of a venture under
which we are financing, constructing and operating a wireless communications
network using the AT&T and SunCom brand names and logos together, giving equal
emphasis to both. AT&T contributed licenses to us in exchange for an equity
interest in us. The venture provides the basis for an alliance between us and
AT&T to provide wireless communications services in particular markets. These
agreements are unique and were heavily negotiated by the parties. The parties
entered into these agreements as a whole, and, taken as a whole, we believe
that the terms of these agreements were no more favorable to any of the parties
than could have been obtained from third parties negotiated at arms' length.
AT&T, as a result of these agreements, owns shares of our capital stock. The
terms of the venture and the alliance are described in a number of agreements,
summaries of which are set forth below. These summaries are qualified by
reference to the agreements, which are exhibits to the registration statement
that we filed with the SEC, including this prospectus.

 Securities Purchase Agreement

   Under a securities purchase agreement, dated as of January 23, 1998, as
amended, among our initial investors, the former stockholders of TeleCorp
Holding, Mr. Vento and Mr. Sullivan and us, we received PCS licenses from AT&T
Wireless and TWR Cellular, Inc. in exchange for shares of our series A
preferred stock, series D preferred stock and series F preferred stock and
$21.0 million in cash. Our initial investors include AT&T Wireless, TWR
Cellular, Chase Capital Partners, Desai Associates, Hoak Capital Corporation,
J. H. Whitney & Co., M/C Partners, One Liberty Fund III, L.P., Toronto Dominion
Investments, Inc. and Northwood Capital Partners. Under the securities purchase
agreement, the initial investors other than AT&T agreed to contribute $128.0
million to us in exchange for shares of our series C preferred stock, class A
common stock, class C common stock, and class D common stock. In addition, the
securities purchase agreement provides that, upon the closing by us of an
acquisition of PCS licenses covering populations of one million or more people,
our initial investors other than AT&T will contribute an additional $5.0
million to us in exchange for additional shares of our series C preferred stock
and class A common stock. This obligation was satisfied in connection with our
purchase of the Digital PCS licenses. Approximately $39.0 million of the
contributions to be made by our initial investors other than AT&T were made
upon the closing of the transactions contemplated by the securities purchase
agreement, which occurred on July 17, 1998, and the remainder of the
contributions will be made over a three-year period. The obligations of such
initial investors to make its remaining contributions are:

  .  irrevocable and unconditional, and not subject to counterclaim, set-off,
     deduction or defense, or to abatement, suspension, deferment, diminution
     or reduction for any reason whatsoever; and

  .  secured by a pledge of the shares of our capital stock issued to each
     such initial investor under the securities purchase agreement.

   See "Management Discussion and Analysis of Financial Condition and Results
of Operations--Liquidity and Capital Resources."

   Under the securities purchase agreement, Mr. Vento and Mr. Sullivan
exchanged their shares of stock in TeleCorp Holding for shares of our series E
preferred stock, class A common stock, class C common stock and class D common
stock. Mr. Vento and Mr. Sullivan also each received 1,545 shares of our voting
preference stock in exchange for shares of stock we previously issued to them.
The other former stockholders of TeleCorp Holding exchanged their shares of
stock in TeleCorp Holding for shares of our series C preferred stock, class A
common stock, class C common stock and class D common stock. The table below
indicates each of the parties to the securities purchase agreement, their
contribution and the consideration received:

   Our initial investors other than AT&T also committed in the securities
purchase agreement to make additional irrevocable equity contributions in the
aggregate amount of $5.0 million in return for the issuance of preferred and
common stock in connection with the Digital PCS acquisition. In addition, upon
the closing of the transactions contemplated by the securities purchase
agreement, we also issued to other members of management shares of our series E
preferred stock and class A common stock. Up to 35.7% of the class A common
stock issued to members of management are under our restricted stock plan.
Shares issued under the restricted stock plan are subject to forfeiture
according to a schedule if employment of such stockholder with us is terminated
within six years after the closing of the securities purchase agreement.

 Stockholders' Agreement

   General. The stockholders' agreement, as amended, among our initial
investors, Messrs. Vento and Sullivan and us sets guidelines for our management
and operations and restricts the sale, transfer or other disposition of our
capital stock.

   Board of Directors. The stockholders' agreement provides that any action of
our board be approved by the affirmative vote of a majority of our entire
board, except in circumstances where voting by particular classes of directors
is required. The stockholders' agreement also provides that, upon closing of
this offering, our board will consist of nine directors.

                                       76
<PAGE>

   The parties to the stockholders' agreement have agreed to vote all of the
shares of class A voting common stock and voting preference stock to cause the
election of the following nine individuals to our board:

  .  Mr. Vento and Mr. Sullivan so long as each remains an officer and the
     management agreement with TeleCorp Management remains in effect;

  .  two individuals selected by holders of a majority in interest of the
     common stock beneficially owned by our initial investors other than
     AT&T;

  .  two additional individuals selected by Mr. Vento and Mr. Sullivan, so
     long as they remain officers, who must be acceptable to the holders of a
     majority in interest of the common stock beneficially owned by our
     initial investors other than AT&T on the one hand, and AT&T Wireless on
     the other hand;

  .  one individual nominated by AT&T Wireless in its capacity as the holder
     of series A preferred stock so long as AT&T has the right to nominate
     one director in accordance with our restated certificate of
     incorporation;

  .  one individual selected by Mr. Vento and Mr. Sullivan, so long as they
     remain officers, who must be acceptable to AT&T Wireless; and

  .  one individual selected by Mr. Vento and Mr. Sullivan, so long as they
     remain officers, who must be acceptable to the holders of a majority in
     interest of the class A voting common stock beneficially owned by our
     initial investors other than AT&T.

   The stockholders agreement provides that when FCC ownership restrictions no
longer apply to us, our board will have seven members and the right of Mr.
Vento and Mr. Sullivan to appoint the individuals set forth in the last two
items above will expire.

   Exclusivity. The parties to the stockholders' agreement have agreed that,
during the term of the stockholders' agreement, neither they nor any of their
respective affiliates will provide or resell, or act as the agent for any
person offering, within the areas covered by our licenses, wireless
communications services initiated or terminated using TDMA and portions of the
airwaves licensed by the FCC, except that AT&T and its affiliates may:

  .  resell or act as agent for us in connection with mobile wireless
     communications services;

  .  provide or resell wireless communications services only to or from
     specific locations, provided that any equipment sold in connection with
     the service must be capable of providing our wireless communications
     services; and

  .  resell mobile wireless communications services from another person in
     any area where we have not placed a system into commercial service.

   Additionally, with respect to some markets identified in the intercarrier
roamer services agreement with AT&T Wireless Services, each of us and AT&T
Wireless has agreed to cause our respective affiliates in their home carrier
capacities to:

  .  program and direct the programming of customer equipment so that the
     other party, in its capacity as the serving carrier, is the preferred
     provider in these markets; and

  .  refrain from inducing any of its customers to change such programming.

   AT&T Wireless has retained some PCS licenses within the areas covered by our
licenses for which we have a right of negotiation in the event of a proposed
transfer.

   If we materially breach any of our obligations, AT&T Wireless may terminate
its exclusivity obligations under the stockholders' agreement and may terminate
our rights to the AT&T brand and logo under the license agreement if a default
continues after the applicable cure periods lapse. These material breaches
include:

  .  AT&T Wireless and its affiliates decide to adopt a new technology
     standard other than TDMA in a majority of its markets, and we decline to
     adopt the new technology;

  .  each portion of our network does not, within one year after being placed
     into service, meet or exceed technical standards that AT&T has developed
     regarding voice quality and performance of network and call completion
     equipment. Each portion of our network must, within one year after being
     placed into service, perform on a level, as measured by these standards
     manuals, that meets or exceeds the levels achieved by the average of all
     comparable wireless communications networks owned and operated by AT&T;

  .  we fail to satisfy specific percentages that our entire network,
     measured as a single system, must meet, including as to percentage of
     calls completed, percentage of established calls that are dropped,
     percentages of calls that are not successfully transferred from one
     network equipment site to another as a handset moves, as well as
     technical standards regarding the functioning of network and call
     connection equipment; or

  .  we fail to meet specified customer care, reception quality and network
     reliability standards.

   In all of our launched markets, we believe we currently meet all of the
standards that we are required to satisfy by the first anniversary of each
launch date.

   The exclusivity provisions in the stockholders' agreement do not apply to
approximately 100,000 people that overlapped with the coverage area of licenses
AT&T purchased from Vanguard Cellular in Strafford, New Hampshire. We have
agreed with AT&T to exchange our licenses covering these people for licenses
covering other people. These exchanged populations will be covered under the
scope of our agreements with AT&T.

   Construction. The stockholders' agreement requires us to construct a PCS
system in the areas covered by our licenses according to a minimum construction
plan, which requires us to construct a system in areas covering:

  .  20% of the total 1995 population of the area covered by our licenses in
     the mainland United States by July 17, 1999, focusing on designated
     areas of Memphis and New Orleans;

  .  30% of the total 1995 population of the area covered by our licenses in
     Puerto Rico and the U.S. Virgin Islands by May 25, 2000, focusing on the
     core urban and suburban cities of the San Juan metropolitan area;

  .  40% of the total 1995 population of the area covered by our licenses in
     Puerto Rico and U.S. Virgin Islands by May 25, 2001, and also focusing
     on secondary cities throughout Puerto Rico;

  .  40% of the total 1995 population of the area covered by our licenses by
     July 17, 2000, and also focusing on designated areas of New England,
     Little Rock and Missouri and enhancing coverage in all markets;

  .  55% of the total 1995 population of the area covered by our licenses in
     the mainland United States by July 17, 2001 and also focusing on
     secondary cities and the important associated connecting highways;

  .  55% of the total 1995 population of the area covered by our licenses in
     Puerto Rico and the U.S. Virgin Islands by May 25, 2002, and continuing
     to expand the secondary cities of Puerto Rico and key cities to the U.S.
     Virgin Islands and the important associated connected highways;

                                       78
<PAGE>

  .  70% of the total 1995 population of the area covered by our licenses in
     the mainland United States by July 17, 2002, and continuing to expand
     the secondary cities and enhancing coverage of the core areas;

  .  70% of the total 1995 population of the area covered by our licenses in
     Puerto Rico and the U.S. Virgin Islands by May 25, 2003, and continuing
     to expand secondary cities and enhancing coverage and capacity of core
     areas;

  .  75% of the total 1995 population of the area covered by our licenses in
     the mainland United States by July 17, 2003, and also focusing on adding
     capacity sites and filling in the remaining suburban areas; and

  .  75% of the total 1995 population of the area covered by our licenses in
     Puerto Rico and the U.S. Virgin Islands by May 25, 2004, and also
     focusing on adding capacity sites and filling in the remaining suburban
     areas.

   In addition to the minimum construction plan, we are bound to do the
following:

  .  arrange for all necessary microwave relocation for our licenses and
     AT&T's retained licenses;

  .  ensure compatibility of our systems with the majority of systems in
     Louisiana, Oklahoma, Minnesota, Illinois and Texas, excluding Houston;

  .  satisfy the FCC construction requirements in the areas covered by our
     licenses and AT&T's retained licenses;

  .  offer service features such as call forwarding, call waiting and
     voicemail with respect to our systems, causing our systems to comply
     with AT&T's network, audio and system performance quality standards; and

  .  refrain from providing or reselling services other than long distance
     services that constitute mobile wireless communications services
     initiated or terminated using TDMA and portions of the airwaves licensed
     by the FCC or that are procured from AT&T.

   Disqualifying Transaction. If AT&T and an entity that:

  .  derives annual revenues from communications businesses in excess of $5
     billion;

  .  derives less than one-third of its aggregate revenues from wireless
     communications; and

  .  owns FCC licenses to offer, and does offer, mobile wireless
     communications services serving more than 25% of the residents, as
     determined by Equifax Marketing Decision Systems Inc., within the areas
     covered by our licenses

merge, consolidate, acquire or dispose of assets to each other, or otherwise
combine, then AT&T, upon written notice to us, may terminate its exclusivity
obligations where the territory covered by our licenses overlaps with
commercial mobile radio service licenses of the business combination partner.
Upon such termination, we have the right to cause AT&T, TWR Cellular, or any
transferee that acquired any shares of series A preferred stock, series D
preferred stock or series F preferred stock owned by AT&T Wireless on July 17,
1998, and any shares of our common stock into which any of these shares are
converted, to exchange their shares into shares of series B preferred stock. If
we decide to convert their shares into shares of series B preferred stock AT&T
may terminate its exclusivity obligations in all of our markets.

   Once so converted, we may redeem the shares of series B preferred stock at
any time in accordance with our restated certificate of incorporation.
Currently, only Sprint, SBC Communications, Bell Atlantic and BellSouth satisfy
the criteria for a business combination partner.

   Under some circumstances, if AT&T proposes to sell, transfer or assign to
any person that is not an affiliate of AT&T Wireless, any PCS system owned and
operated by AT&T Wireless and its affiliates in any of the St. Louis, Missouri,
Louisville, Kentucky, or Boston, Massachusetts basic trading areas, then AT&T
must provide us with the opportunity to offer our network for sale jointly with
AT&T for a 90-day period.

                                       79

   Acquisition of Licenses. The stockholders' agreement provides that we may
acquire any cellular license that our board has determined is a demonstrably
superior alternative to constructing a PCS system within the corresponding
areas covered by our licenses, if:

  .  a majority of the population covered by the license is within the areas
     covered by our licenses;

  .  AT&T Wireless and its affiliates do not own commercial mobile radio
     service licenses in the area covered by the license; and

  .  our ownership of the license will not cause AT&T Wireless or any
     affiliate to be in breach of any law or contract.

   Vendor Discounts; Roaming Agreements. AT&T Wireless has agreed in the
stockholders' agreement that, if we so request, and if such request shall not
result in any adverse impact to AT&T Wireless PCS, it will use all commercially
reasonable efforts:

  .  to assist us in obtaining discounts from any AT&T Wireless vendor with
     whom we are negotiating for the purchase of any infrastructure equipment
     or billing services; and

  .  to enable us to become a party to the roaming agreements between AT&T
     Wireless and its affiliates and operators of other cellular and PCS
     systems.

   Resale Agreements. We, upon the request of AT&T Wireless, will enter into
resale agreements relating to the areas covered by our licenses under which
AT&T may resell our services. The rates, terms and conditions of service that
we provide are to be at least as favorable, and to the extent permitted by
applicable law, more favorable, to AT&T Wireless, taken as a whole, as the
rates, terms and conditions that we provide to other customers.

   Subsidiaries. The stockholders' agreement provides that all of our
subsidiaries must be direct or indirect wholly owned subsidiaries. The
stockholders' agreement also provides that, without the prior written consent
of, or right of first offer to, AT&T Wireless, we and our subsidiaries may not:

  .  sell or dispose of a substantial portion of our assets or the assets of
     any of our subsidiaries; or

  .  liquidate, merge or consolidate until we meet minimum construction
     requirements.

   Restrictions on Transfer. The stockholders' agreement restricts the sale,
transfer or other disposition of our capital stock, such as by giving rights of
first offer, drag along and tag along rights and providing demand and piggyback
registration rights.

   If one of our stockholders who is a party to the stockholders' agreement
desires to transfer any or all of its shares of preferred or common stock,
other than voting preference stock and class C common stock, the selling
stockholder must first give written notice to us and:

  .  if the selling stockholder is one of our initial investors other than
     AT&T or any other stockholder who is a party to the stockholders'
     agreement, to AT&T Wireless; and

  .  if the selling stockholder is AT&T Wireless or TWR Cellular, to every
     other initial investor.

   The stockholders who receive notice from the selling stockholders may
acquire all, but not less than all, of the shares offered to be sold at the
price offered by the selling stockholder. If none of the stockholders opt to
purchase the shares of the selling stockholder, the selling stockholder can
sell its shares to any other person on the same terms and conditions as
originally offered to the stockholders. The right of first offer does not apply
to our repurchase of any shares of our class A common stock or class E
preferred stock from one of our employees in connection with the termination of
the employee's employment with us.

                                       80
<PAGE>

   A stockholder subject to the stockholders' agreement may not transfer 25% or
more of any of the following shares of our capital stock, whether alone or with
other stockholders or whether in one transaction or a series of transactions:

  .  series A preferred stock;

  .  series C preferred stock;

  .  series D preferred stock;

  .  series E preferred stock;

  .  series F preferred stock;

  .  voting preference stock;

  .  class A common stock;

  .  class B common stock;

  .  class C common stock; or

  .  class D common stock,

unless the proposed transfer includes an offer to our initial investors and Mr.
Vento and Mr. Sullivan to join in the transfer. Class C common stock and class
D common stock will count as one class of stock for purposes of the 25% test.
If a selling stockholder receives an offer from a bona fide purchaser to
transfer a selling stockholder's shares, the selling stockholder must follow
procedures included in the stockholders' agreement to include the other
stockholders in the proposed transfer.

   In addition to the foregoing restrictions, the initial investors have agreed
not to transfer any shares of their common stock until July 17, 2001 except to
affiliates, and Mr. Vento and Mr. Sullivan have agreed not to transfer any
shares of common stock prior to July 17, 2003, subject to limited exceptions,
including that 25% of their common stock may be transferred after July 17,
2001. In addition, some of our stockholders, including our initial investors,
Mr. Vento and Mr. Sullivan, are subject to restrictions imposed by the
underwriters prohibiting them from transferring any shares of their capital
stock for 180 days.

   Our stockholders who are subject to the stockholders' agreement also have
demand and piggyback registration rights. In some circumstances, stockholders
may demand that we register some or all of their securities with the SEC under
the Securities Act. See "Shares Eligible for Resale." Also, if we propose to
register any shares of our class A common stock or securities convertible into
or exchangeable for class A voting common stock with the SEC under the
Securities Act, we must notify all stockholders of our intention to do so, and
our stockholders may include in our registration their shares of class A voting
stock or securities convertible into or exchangeable for class A common stock.

   Amendments. In addition to the approval of our senior lenders, the terms of
the stockholders' agreement may be amended only if agreed to in writing by us
and the beneficial holders of a majority of the class A common stock party to
the stockholders' agreement, including AT&T Wireless, 66 2/3% of the class A
common stock beneficially owned by our initial investors other than AT&T, and
66 2/3% of the class A common stock beneficially owned by Mr. Vento and
Mr. Sullivan.

   Termination. The stockholders' agreement will terminate upon the earliest to
occur of:

  .  the receipt of the written consent of each party;

  .  July 17, 2009; and

  .  under specified circumstances, the date on which a single stockholder
     beneficially owns all of the outstanding shares of class A common stock.

                                       81

 Network Membership License Agreement

   Under a network license agreement dated as of July 17, 1998 between AT&T and
us, AT&T granted to us a royalty-free, non-transferable, non-sublicensable,
non-exclusive, limited license to use some of their licensed marks in our
markets, including:

  .  the logo containing the AT&T name and globe design;

  .  the expression "Member, AT&T Wireless Services Network"; and

  .  AT&T colors, graphics and overall configurations,

   The licensed marks may only be used in connection with licensed activities.
These licensed activities include:

  .  providing to our customers and resellers of our wireless services,
     solely within the areas covered by our licenses, mobile wireless
     communications services; and

  .  marketing and offering the licensed services within the areas covered by
     our licenses with limited advertising outside our licensed area.

   The license agreement also grants to us the right to use licensed marks on
specified mobile phones distributed to our customers.

   Except in specified instances, AT&T has agreed not to grant to any other
person a right to provide or resell, or act as agent for any person offering,
mobile wireless communications services under the licensed marks in our
licensed markets. AT&T retains all rights of ownership in the licensed marks,
subject to its exclusivity obligations to us, in both the areas covered by our
licenses and all other areas.

   The license agreement restricts our use and modification of any of the
licensed marks. Although we may develop our own marks, we may not use them
together with the licensed marks without the prior approval of AT&T. Any
services we market or provide using the licensed marks must be of comparable
quality to similar services that AT&T markets and provides in areas that are
comparable to the areas covered by our licenses. We may take into account
commercial reasonableness and the relative stage of development of the licensed
areas, to determine what is comparable service. We must also provide
sufficiently high quality services to provide maximum enhancement to and
protect licensed marks, such as attaining specified levels of network quality,
audio quality, system performance and meeting customer care standards. The
license agreement also defines specific testing procedures to determine
compliance with these standards and affords us with a grace period to cure any
instances of noncompliance. Following the cure period, we must stop using the
licensed marks until we comply with the standards, or we may be deemed to be in
breach of the license agreement and we may lose our rights to the licensed
marks.

   We may not assign, sublicense or transfer, by change of control or
otherwise, any of our rights under the license agreement, except that the
license agreement may be, and has been, assigned to our lenders under our
senior credit facilities. After the expiration of any applicable grace and cure
periods under our senior credit facilities, the lenders may then enforce our
rights under the license agreement and assign the license agreement to any
person with AT&T's consent.

   The initial term of the license agreement is for a period of five years,
which will be automatically renewed for an additional five-year period if each
party gives written notice to the other party of our election to renew the
license agreement and neither party gives notice of non-renewal.

   The license agreement may be terminated by AT&T at any time in the event of
our significant breach and the exhaustion of any applicable cure periods, which
include:

  .  our misuse of any licensed marks;

                                       82
<PAGE>

  .  our bankruptcy;

  .  our licensing or assignment of any of our rights under the license
     agreement, except as permitted by the terms of the license agreement;

  .  our loss of the licenses acquired from AT&T;

  .  our failure to maintain AT&T's quality standards in any material
     respect; or

  .  our change of control, which is defined as a transaction, other than a
     transfer by AT&T, that results in any person other than our initial
     stockholders or our senior lenders acquiring beneficial ownership of
     more than 50% of our voting stock, or 33.3% of our voting stock if the
     person acquiring our stock acquires more than our initial stockholders
     hold at that time. Also included is a transaction that results in any of
     the three largest telecommunications carriers, excluding AT&T and any
     wireless carrier using TDMA technology, or any regional bell operating
     company, or Microsoft acquiring more than 15% of our voting stock,
     excluding acquisitions through open market transactions or a majority of
     our directors are removed in a proxy contest.

Our rights under the license agreement are also subject to the minimum
construction plan set forth in the stockholders' agreement. For more
information concerning the minimum construction plan, see the discussion under
"Stockholders' Agreement" under the heading "A&T Agreements." After the
initial term, AT&T may also terminate the license agreement in connection with
a disqualifying transaction.

   Upon closing of the Digital PCS acquisition, the license agreement was
automatically amended to include the Baton Rouge, Houma, Hammond and
Lafayette, Louisiana basic trading areas under its scope. Upon closing of the
Puerto Rico acquisition, the license agreement was automatically amended to
include the San Juan major trading area under its scope. Upon the closing of
the Wireless 2000 acquisition, the license agreement was automatically amended
to include the Alexandria and Lake Charles, Louisiana basic trading areas and
certain other counties under the Monroe, Louisiana basic trading area under
its scope.

 Intercarrier Roamer Service Agreement/Roaming Administration Service
 Agreement

   Intercarrier Roamer Service Agreement. We entered into the intercarrier
roamer services agreement dated as of July 17, 1998 with AT&T Wireless
Services and several of its affiliates. We have agreed with AT&T Wireless that
each party, in its capacity as a serving provider, will provide services to
each others customers where it has a license or permit to operate a wireless
communications system. Each home carrier whose customers receive service from
a serving provider will pay to the serving provider all of the serving
provider's charges for wireless service and all of the applicable charges.
Each serving provider's service charges per minute or partial minute for use
for the first three years will be fixed at a declining rate.

   The intercarrier roamer service agreement has a term of 20 years, which is
automatically renewed on a year-to-year basis unless terminated by either
party upon 90 days prior written notice after 10 years. The intercarrier
roamer service agreement may be terminated immediately by either party upon
written notice to the other of a default of the other party. A party will be
in default under the intercarrier roamer service agreement upon any of the
following:

  .  material breach of any material term of the intercarrier roamer service
     agreement by a party that continues for thirty days after receipt of
     written notice of the breach from the nonbreaching party;

  .  voluntary liquidation or dissolution or the approval by the management
     or owners of a party of any plan or arrangement for the voluntary
     liquidation or dissolution of the party; or

  .  bankruptcy or insolvency of a party.

   The intercarrier roamer service agreement may also be suspended by either
party immediately upon written notice to the other party of the existence of a
breach of the agreement, whether or not the breach constitutes a default, if
the breach materially affects the service being provided to the customers of
the non-

                                      83
<PAGE>

breaching party. While the suspension is in effect, either in whole or in part,
the parties will work together to resolve as quickly as possible the difficulty
that caused the suspension. When the party who originally gave notice of
suspension concludes that the problem causing the suspension has been resolved,
that party will give to the other written notice to this effect, and the
agreement will resume in full effect within five business days after the
parties have mutually agreed that the problem has been resolved. Neither party
may assign or transfer its rights and obligations under the intercarrier roamer
service agreement without the written consent of the other party, except to an
affiliate or an assignee of its license.

   Roaming Administrative Service Agreement. Under the roaming administrative
service agreement dated as of July 17, 1998 between AT&T Wireless and us, AT&T
Wireless has agreed to make available to us the benefits of the intercarrier
roaming services agreements it has entered into with other wireless carriers,
subject to the consent of the other wireless carriers and to our remaining a
member in good standing of the North American Cellular Network.

   The roaming administrative service agreement has an initial term of two
years, which is automatically renewed on a year-to-year basis unless terminated
by either party upon 90 days prior written notice. Either party may terminate
the roaming administrative service agreement for any reason at any time upon
180 days prior written notice. Either party may also terminate the roaming
administrative service agreement:

  .  upon a material breach of the other party that is not cured or for which
     cure is not reasonably begun within 30 days after written notice of the
     claimed breach; or

  .  immediately by either party, after reasonable prior notice, if the other
     party's operations materially and unreasonably interfere with its
     operations and the interference is not eliminated within 10 days.

   AT&T Wireless can terminate the roaming administrative service agreement if:

  .  we are no longer a member in good standing of the North American
     Cellular Network; or

  .  the agreement under which AT&T Wireless receives roaming administration
     services is terminated or expires; provided, however, that AT&T Wireless
     will offer to resume its services in the event that it extends or
     continues that agreement.

   Neither party may assign or transfer its rights and obligations under the
roaming administrative service agreement without the written consent of the
other party, except to an affiliate or an assignee of its license, except that
AT&T Wireless may subcontract its duties.

 Resale Agreement

   The stockholders' agreement provides that, from time to time, at AT&T
Wireless' request, we are required to enter into a resale agreement with AT&T
Wireless PCS or other of its affiliates. The resale agreement would grant to
AT&T Wireless the right to purchase from us our wireless services on a non-
exclusive basis within a designated area and resell access to, and use of, our
services. AT&T Wireless must pay charges for any services that are resold,
including usage, roaming, directory assistance and long distance charges, and
taxes and tariffs. Any resale agreement would have an initial term of ten years
that would be automatically renewed on a year-to-year basis unless terminated
by either party upon 90 days prior written notice. In addition, AT&T Wireless
would be able to terminate any resale agreement for any reason at any time upon
180 days prior written notice.

 Long Distance Agreement

   Under the long distance agreement dated as of December 21, 1998 between AT&T
Wireless and us, we purchase interstate and intrastate long distance services
from AT&T Wireless at preferred rates. We then resell these long distance
services to our customers. We can only obtain these preferred rates if we
continue our affiliation with AT&T Wireless. The long distance agreement has a
term of up to three years.

   The long distance agreement requires that we meet a minimum traffic volume
during the term of the agreement, which are adjusted at least once each
calendar year at the time specified by AT&T Wireless. The

                                       84
<PAGE>

minimum traffic volume commitments may be adjusted more frequently upon mutual
agreement by AT&T Wireless and us. During the first year, we set the minimum
traffic volume commitment in our sole discretion. After the first calendar
year, the commitment may be increased by any amount or decreased by any amount
up to ten percent at our discretion. We may reduce the minimum traffic volume
commitments by more than ten percent with AT&T Wireless' permission. If we fail
to meet the volume commitments, we must pay to AT&T Wireless the difference
between the expected fee based on the volume commitment and the fees based on
actual volume.

   The long distance services we purchase from AT&T Wireless may only be used
in connection with:

  .  our commercial mobile radio services;

  .  calls that originate on our network; and

  .  those commercial mobile radio services that share our call connection
     equipment.

 Puerto Rico License

   In a series of transactions, we acquired a license and related assets
covering the San Juan major trading area from AT&T Wireless on May 25, 1999.
The following transactions took place ultimately to effect the acquisition of
the license and related assets from AT&T Wireless:

  .  on May 24, 1999, we sold to AT&T for $40.0 million 30,750 shares of our
     series A preferred stock, 10,250 shares of our series D preferred stock,
     and 3,090,000 shares of our series F preferred stock under a preferred
     stock purchase agreement;

  .  on May 25, 1999, we sold to our initial investors other than AT&T 39,997
     shares of our series C preferred stock and 12,358,950 shares of our
     class A common stock in exchange for an aggregate amount of $40.0
     million in cash under a stock purchase agreement, which will be funded
     over a three-year period.

  .  on May 25, 1999, we purchased the license for the San Juan major trading
     area and related assets, which included 27 constructed network equipment
     sites, call connection equipment and leases for additional network
     equipment sites, from AT&T for $96.5 million in cash under an asset
     purchase agreement; and

  .  we reimbursed AT&T $3.2 million for microwave relocation and $1.5
     million for other expenses it incurred in connection with this
     acquisition.

   In addition, Mr. Vento and Mr. Sullivan were issued fixed and variable
awards of 4,063 and 1,633,899 restricted shares of our series E preferred stock
and class A common stock, respectively, in exchange for their interest in
Puerto Rico Acquisition Corporation. Puerto Rico Acquisition Corporation was an
entity wholly-owned by Mr. Vento and Mr. Sullivan that was created for the
special purpose of acquiring the license and related assets of the San Juan
major trading area. The fixed awards typically vest over a five-year period.

   The stockholders' agreement sets forth network development requirements for
the Puerto Rico license. See "Certain Relationships and Related Transactions--
Stockholders Agreement--Construction."

   The San Juan major trading area covers a population of approximately 3.9
million in Puerto Rico, as well as the U.S. Virgin Islands. Our agreements with
AT&T were automatically amended to include the San Juan major trading area
under the scope of those agreements.

1999 Stock Option Plan

   On July 22, 1999, we implemented a 1999 Stock Option Plan to award employees
and members of the board options to acquire shares of our class A common stock.
Our board granted options to purchase 552,505 shares of class A common stock
under the plan with an exercise price equal to the fair market value of the
underlying stock at the date of the grant. For information regarding grants
under the plan, see "Management--1999 Stock Option Plan."

                                       85
<PAGE>

Management Agreement

   As of July 17, 1998, we entered into a management agreement with TeleCorp
Management, a company owned by Mr. Vento and Mr. Sullivan under which TeleCorp
Management provides to us administrative, operational, marketing, regulatory
and general business services. For information regarding compensation payable
under the management agreement, see "Management--Management Agreement."

   The terms of this agreement were no more favorable to the parties than they
could have obtained from third parties negotiated at arms' length.

Other Related Party Transactions

 Relationship with Entel Technologies and other Site Acquisition Service
 Providers

   We receive site acquisition, construction management, program management,
microwave relocation and engineering services under a master services agreement
with Wireless Facilities, Inc. Payments under the agreement were approximately
$30.7 million in the 1998 fiscal year. At the time of entering into the master
services agreement, Mr. Vento was a senior officer, and he and Mr. Sullivan
were the controlling stockholders, of Entel Technologies. In February 1998,
they sold their interests in Entel Technologies to Wireless Facilities, Inc.
The terms of this agreement were no more favorable to the parties than they
could have obtained from third parties negotiated at arms' length.

   American Towers, Inc. provides us with network site leases for PCS
deployment under a master site lease agreement. Chase Capital Partners, one of
our beneficial owners, has a noncontrolling interest in American Towers. The
terms of these lease agreements were no more favorable to the parties than they
could have obtained from third parties negotiated at arms' length.

 Relationship with the Initial Purchasers of the Senior Subordinated Discount
 Notes

   Chase Securities Inc. was one of the initial purchasers of the outstanding
notes. Chase Securities Inc. and its affiliates perform various investment
banking and commercial banking services from time to time for us and our
affiliates. Chase Securities Inc. acted as our lead manager for our offering of
our senior subordinated discount notes. The Chase Manhattan Bank, an affiliate
of Chase Securities Inc., is the agent bank and a lender under our senior
credit facilities. Michael R. Hannon, a member of our board, is a General
Partner of Chase Capital Partners, an affiliate of Chase Securities Inc. In
addition, CB Capital Investors, L.P., an affiliate of Chase Capital Partners,
is one of our initial investors and owns shares of our common and preferred
stock. For further information concerning these relationships, see
"Management," "Principal Stockholders and Beneficial Ownership of Management"
and "Underwriting." The terms of our senior credit facilities were no more
favorable to the parties than they could have obtained from third parties
negotiated at arms' length.

 Relationships with Tritel Communications and Triton PCS

   We have formed Affiliate License Co. with Triton PCS and Tritel
Communications to adopt a common brand, SunCom, that is co-branded with AT&T on
an equal emphasis basis. Under the agreement, we, Triton PCS and Tritel
Communications each own one third of Affiliate License Co., the owner of the
SunCom name. We and the other SunCom companies license the SunCom name from
Affiliate License Co. Mr. Sullivan is a director of Affiliate License Co. The
terms of this agreement were no more favorable to the parties than they could
have obtained from third parties negotiated at arms' length.

   Tritel Communications owned a controlling interest in Digital PCS at the
time we acquired licenses from Digital PCS. Tritel Communications may be
deemed an affiliate of Digital PCS. In addition, at the time we acquired
licenses from Digital PCS, Mr. Anderson and Mr. Fuqua were directors of Tritel
Communications. See "Business--Recent Developments." The terms of this
agreement were no more favorable to the parties than they could have obtained
from third parties negotiated at arms' length.

 Relationship with Other Entities

   TeleCorp Holding. TeleCorp Holding, our predecessor company, was
incorporated to participate in the FCC's auction of licenses in April 1997.
TeleCorp Holding raised money from investors to develop any licenses it
obtained in the auction. TeleCorp Holding successfully obtained licenses in
the New Orleans, Memphis, Beaumont, Little Rock, Houston, Tampa, Melbourne and
Orlando basic trading areas. In August 1997, TeleCorp Holding transferred the
Houston, Tampa, Melbourne and Orlando basic trading area licenses to four
newly-formed entities created by TeleCorp Holding's stockholders:

  .  THC of Houston;

  .  THC of Tampa;

  .  THC of Melbourne; and

  .  THC of Orlando;

and issued notes in the aggregate amount of approximately $2.7 million to
these entities to develop these licenses. These licenses were transferred
along with the related operating assets and liabilities in exchange for
investment units consisting of class A, B and C common stock and series A
preferred stock in August 1997. Concurrently, TeleCorp Holding distributed the
investment units, on a pro rata basis, in a partial stock redemption to
TeleCorp Holding's existing stockholder group. As a result of this
distribution, TeleCorp Holding no longer retains any ownership equity interest
in the newly formed entities. TeleCorp Holding performed administrative and
management services and paid costs on behalf of these entities for the year
ended December 31, 1997 worth the aggregate amount of $0.7 million. In 1998,
upon the closing of the agreements with AT&T, TeleCorp Holding paid
approximately $2.0 million to the four THC entities as payment of the notes,
offset by the approximately $0.7 million in services and costs. The terms of
these transactions were no more favorable to the parties than they could have
obtained from third parties negotiated at arms' length.

   TeleCorp WCS. On May 5, 1997, TeleCorp Holding lent approximately $3.0
million to TeleCorp WCS, Inc. in exchange for interest-free notes from
TeleCorp WCS. On May 5, 1997, TeleCorp Holding received equity investments in
exchange for the right to receive:

  .  the notes from TeleCorp WCS;

  .  any cash, notes or other assets received by TeleCorp Holding on behalf
     of the notes; or

  .  any capital stock into which the notes were converted.

   TeleCorp WCS repaid approximately $2.7 million of the notes with cash to
TeleCorp Holding, and TeleCorp Holding forwarded this cash to the equity
investors. TeleCorp WCS issued a note in the amount of approximately $0.3
million directly to the investors on behalf of the remaining $0.3 million
outstanding under the notes. TeleCorp WCS converted these notes into capital
stock issued to the investors in 1998.

                                      87
<PAGE>

   Mr. Sullivan and Mr. Vento own 2,875 and 4,625 shares of class C common
stock of TeleCorp WCS, respectively, which represents 60% of its outstanding
class A common stock. At the time of entering into the transactions with
TeleCorp WCS, Mr. Sullivan and Mr. Vento were stockholders in TeleCorp Holding.

   The terms of these transactions were no more favorable to the parties than
they could have obtained from third parties negotiated at arms' length.

   TeleCorp Investment Corp.; TeleCorp Investment Corp. II.  TeleCorp
Investment Corp. owns 352,956 shares of our class A common stock, 575 shares of
our class C common stock, 3,780 shares of our class D common stock and 1,160.17
shares of our series C preferred stock. Some of our stockholders own stock in
TeleCorp Investment Corp., as follows:

  .  Chase Capital Partners, one of our initial investors, owns an 80% equity
     interest;

  .  Mr. Sullivan and Mr. Vento each own a 2.4% equity interest;

  .  Mr. Chandler owns a 2.0% equity interest; and

  .  Mr. Dowski owns a 1.6% equity interest.

   In addition, TeleCorp Investment Corp. II was formed to purchase from
Entergy Technology Holding Corporation 492,064 shares of class A common stock
and 11,366 shares of class D common stock. The purchase of shares was concluded
on July 15, 1999. Mr. Vento, Mr. Sullivan and Ms. Dobson each own 5.99% of
TeleCorp Investment Corp. II. Mr. Vento and Mr. Sullivan serve as managers of
TeleCorp Investment Corp. II.

   The terms of these transactions were no more favorable to the parties than
they could have obtained from third parties negotiated at arms' length.

   Viper Wireless.  Viper Wireless was formed to participate in the FCC's
reauction of PCS licenses in most of our markets. TeleCorp Holding owns 85% of
Viper Wireless, and Mr. Vento and Mr. Sullivan collectively own the remaining
15%. Mr. Vento and Mr. Sullivan collectively have voting control over Viper
Wireless. On September 30, 1999, we solicited the approval of the FCC for the
transfer of the shares of Viper Wireless we do not yet own to TeleCorp Holding.

   AT&T and some of our other initial investors have funded an aggregate of
approximately $32.3 million in exchange for additional shares of our preferred
and common stock in connection with the Viper Wireless reauction. AT&T received
one share each of our series D preferred stock and our series F preferred
stock, and each of the other participating initial investors received one share
each of our class A common stock and our series C preferred stock, for each
$1,000 of the pro rata portion of the amount we invested in Viper Wireless,
which is based upon their portion of the aggregate amount. Additionally, upon
approval of the FCC, some of our employees, Mr. Vento and Mr. Sullivan will
receive a total of 1,111 shares of series E preferred stock and 503,022 shares
of class A common stock. Our employees will receive their shares as restricted
stock that will vest ratably over 5 years. Mr. Vento and Mr. Sullivan will
receive their shares in exchange for shares they hold in Viper Wireless, and
their shares will vest immediately. The estimated value of the series E
preferred stock is $81,092, and of the class A common stock is $10,060,440. As
part of this financing, we paid approximately $0.5 million to Chase Securities,
Inc., an initial purchaser and an affiliate of one of our initial investors,
for placement advice. The terms of these transactions were no more favorable to
the parties than they could have obtained from third parties negotiated at
arms' length.

   On April 20, 1999, the FCC announced that the reauction ended, and Viper
Wireless was the higher bidder for additional portions of the airwaves in New
Orleans, Houma and Alexandria, Louisiana, San Juan, Puerto Rico, Jackson,
Tennessee and Beaumont, Texas. The FCC has granted us all of these licenses.
AT&T and the investors funded a total of approximately $32.3 million to satisfy
Viper Wireless' payment to the FCC.

 TeleCorp LMDS

   On October 18, 1999, we agreed to acquire TeleCorp LMDS, Inc. through an
exchange of all of the outstanding stock of TeleCorp LMDS for 834,300 shares of
our class A common stock and 2,700 shares of our series C preferred stock.
TeleCorp LMDS's stockholders are Mr. Vento, Mr. Sullivan and three of our
initial investors. By acquiring TeleCorp LMDS, we will gain LMDS licenses
covering airwaves in Little Rock, Arkansas, Beaumont, Texas, New Orleans,
Louisiana, San Juan and Mayaguez, Puerto Rico, and the U.S. Virgin Islands. See
"Principal Stockholders and Beneficial Ownership of Management."

 Relationship with Toronto Dominion

   Toronto Dominion Investments, one of our initial investors, and TD
Securities (USA), an affiliate of Toronto Dominion Investments, which is a
lender under our senior credit facilities, may be deemed to be under common
control by virtue of their relationship to each other and to us. The terms of
our senior credit facilities were no more favorable to the parties than they
could have obtained from third parties negotiated at arms' length.

 Relationships with Stockholders

   From inception through June 1998, our primary source of financing was notes
issued to some of our initial investors. In July 1996, we issued $0.5 million
of subordinated promissory notes to such investors. These notes were converted
into 50 shares of our series A preferred stock in April 1997. In December 1997,
we issued various promissory notes to some of our initial investors. These
notes were converted into mandatorily redeemable preferred stock in July 1998.
From January 1, 1998 to June 30, 1998, we borrowed approximately $22.5 million
in the form of promissory notes to existing and prospective investors to
satisfy working capital needs. These notes were converted into equity in July
1998 in connection with the completion of the venture with AT&T.

   The terms of these transactions were no more favorable to the parties than
they could have obtained from third parties negotiated at arms' length.

 Relationship with McDermott, Will & Emery

   We use the services of a law firm, McDermott, Will & Emery, to which Mr.
Sullivan, our executive vice president, was counsel until October 1999 and a
partner prior to July 1998. The terms of these arrangements were no more
favorable to McDermott, Will & Emery than could have been obtained from third
parties negotiated at arms' length.

                          DESCRIPTION OF INDEBTEDNESS

Senior Credit Facilities

   Our credit agreement, as amended, provides for senior credit facilities for
$560.0 million with several lenders, including The Chase Manhattan Bank, as
administrative agent and issuing bank, TD Securities (USA) Inc., as syndication
agent, and Bankers Trust Company, as documentation agent.

   The senior credit facilities provide for:

  .  a $150.0 million senior secured term loan, the tranche A term loan,
     which matures in January 2007;

  .  a $225.0 million senior secured term loan, the tranche B term loan,
     which matures in January 2008;

  .  a $150.0 million senior secured revolving credit facility, which matures
     in January 2007; and

  .  a $35.0 million senior secured term loan, the tranche C term loan,
     established under an expansion facility, which matures in May 2009.

   The tranche A term loan is required to be repaid, beginning in September
2002, in 18 consecutive quarterly installments. The amount of each of the first
six installments is $3.75 million. The amount of each of the next four
installments is approximately $9.4 million. The amount of each of the last
eight installments is $11.25 million. The tranche B term loan is required to be
repaid, beginning in September 2002, in 22 consecutive quarterly installments.
The amount of each of the first 18 installments is approximately $0.6 million.
The amount of each of the last four installments is approximately $54.0
million. The tranche C term loan is required to be repaid in May 2009. The
commitments to make loans under the revolving credit facility automatically and
permanently reduce, beginning in April 2005, in eight consecutive quarterly
reductions. The amount of each of the first four reductions is $12.5 million.
The amount of each of the last four reductions is $25.0 million.

   We may select the rate at which interest accrues on all loans. We may choose
a eurodollar loan, which accrues at a reserve-adjusted London Interbank
Offering Rate, with a margin equal to:

  .  between 1.25% and 2.75% per annum, depending upon our leverage ratio,
     with respect to the tranche A Term loan and the revolving credit loans;
     and

  .  3.0% per annum, with respect to the tranche B term loan.

   Alternatively, we may choose an alternative rate loan, which accrues at the
higher of (a) the administrative agent's prime rate and (b) the federal funds
rate plus 0.50% plus, in each case,

  .  a rate between 0.25% and 1.75% per annum, depending on our leverage
     ratio with respect to the tranche A term loan and the revolving credit
     loans; and

  .  2.0% per annum, with respect to the tranche B term loan.

  .  2.0% per annum, with respect to the tranche C term loan.

   Interest on any overdue amounts will accrue at a rate per annum equal to
2.00% plus the rate otherwise applicable to these amounts.

   The terms of the senior credit facilities require us to pay a commitment fee
accruing at an annual rate of between 0.50% and 1.25% on the unused portion of
the revolving credit and tranche A term loan facilities, depending on the
percentage of undrawn tranche A and revolving credit commitments. The
commitment fees are payable quarterly in arrears, and a separate agent's fee is
payable to the administrative agent. The senior credit facilities also require
us to purchase an interest rate hedging contract covering an amount equal to at
least 50% of the total amount of our outstanding indebtedness, excluding
indebtedness that bears interest at a fixed rate. As of December 31, 1998 and
September 30, 1999, we hedged 100% of our outstanding indebtedness under our
senior credit facilities of $225,000,000 to take advantage of favorable
interest rate swaps. The six outstanding interest rate swap contracts fix LIBOR
at annual interest rates from 5.20% to 5.26%. The contracts mature in September
of 2003.


                                       90
<PAGE>

   The tranche A term loan automatically will be reduced to the extent its
undrawn portion exceeds $50.0 million in July 2000 by the amount of the excess.
The term loans will be prepaid, and commitments under the revolving credit
facility will be reduced, in an aggregate amount equal to:

  (1) 50% of the excess cash flow of each fiscal year beginning with the
      fiscal year ending December 31, 2001;

  (2) 100% of the net proceeds of asset sales outside of the ordinary course
      of business, in excess of a $1.0 million annual threshold, or unused
      insurance proceeds; and

  (3) 100% of the net cash proceeds of issuances of debt obligations, other
      than debt obligations permitted by the senior credit agreement;
      provided that the prepayments and reductions will not be required if,
      after giving effect to the issuance, our leverage ratio would be less
      than 5.0 to 1.0.

   Each of our existing and future domestic subsidiaries unconditionally
guarantees all our obligations under the senior credit facilities. The
facilities and the credit facility subsidiary guarantees, and any related
hedging contracts provided by the lenders under the senior credit facilities,
are secured by substantially all of our assets and the assets of each of our
existing and future domestic subsidiaries, including a first priority pledge of
all of the capital stock held by us or any of our subsidiaries. Under the
senior credit facilities, no action may be taken against our licenses unless
and until the requisite approval is obtained from the FCC.

   The senior credit agreement contains financial and other covenants customary
for senior credit agreements. The senior credit agreement also contains
customary representations, warranties, indemnities, conditions precedent to
borrowing and events of default.

   Borrowings under the senior credit facilities are available to finance
capital expenditures related to the construction of our network, the
acquisition of related businesses, working capital needs and subscriber
acquisition costs.

Senior Subordinated Discount Notes

   On April 20, 1999, we sold $575,000,000 aggregate principal amount at
maturity of 11 5/8% senior subordinated discount notes due April 15, 2009. Cash
interest on these notes will not accrue or be payable prior to April 15, 2004.
From April 15, 2004, cash interest will accrue at a rate of 11 5/8% per annum
on the principal amount at maturity of the notes through and including the
maturity date and will be payable semi-annually on April 15 and October 15 of
each year. In connection with the sale of these notes, we received net proceeds
of approximately $317 million after deducting initial purchasers' discount and
issuance expenses of approximately $11 million.

   These notes are general senior unsecured obligations subordinate to all of
our existing and future senior debt and will rank equally in right of payment
with all our existing and future unsecured and unsubordinated indebtedness and
senior in right of payment to any of our subordinated indebtedness. The notes
are guaranteed by our subsidiary, Telecorp Communications, Inc., and may be
guaranteed by future subsidiaries. The notes are redeemable at any time and
from time to time at our option, in whole or in part on or after April 15,
2004, plus accrued and unpaid interest. The redemption prices for the senior
subordinated discount notes, if redeemed during the 12-month period beginning
on April 15 of the years described below are as follows:

</TABLE>

                                       91
<PAGE>

   In addition, on or prior to April 15, 2002, we may redeem, at our option,
up to 35% of the aggregate principal amount at maturity of the notes with the
net proceeds of one or more equity offerings, at 111.625% of the accreted
value thereof, as long as notes representing at least 65% of the aggregate
initial accreted value of the notes originally issued remain outstanding after
each redemption and that the redemption occurs within 60 days of the closing
of any equity offering.

   If we experience a change of control, each holder of senior subordinated
discount notes will have the right to require us to repurchase all or any part
of the holder's notes at a purchase price in cash equal to:

     (1) 101% of the accreted value on the purchase date, if the date is on
  or before April 15, 2004; or

     (2) 101% of the principal amount at maturity, plus accrued and unpaid
  interest, if any, to the purchase date, if the date is after April 15,
  2004.

   A change of control would occur under the indenture if any of the following
occurs:

  .  any person or group, as the terms are used in the applicable provisions
     of the Securities Exchange Act of 1934, other than some permitted
     holders, becomes the beneficial owners, as defined in the beneficial
     ownership provisions under the Exchange Act, except that a person shall
     be deemed to have beneficial ownership of all the securities that the
     person has the right to acquire within one year, upon the happening of
     an event or otherwise, directly or indirectly, of our securities
     representing 50% or more of the combined voting power of our then
     outstanding voting stock;

  .  the following individuals cease for any reason to constitute more than a
     majority of the number of directors then serving on our board:
     individuals who, on April 23, 1999, constituted our board and any new
     director, other than a director whose initial assumption of office is in
     connection with an actual or threatened election contest, including, but
     not limited to, a consent solicitation relating to the election of our
     directors, whose appointment or election by our board or nomination for
     election by our stockholders was approved by the vote of at least two-
     thirds of the directors then still in office or whose appointment,
     election or nomination was previously so approved or recommended or made
     in accordance with the terms of the stockholders' agreement; or

  .  our stockholders shall approve any plan of liquidation, whether or not
     otherwise in compliance with the provisions of the indenture.

   The indenture under which the notes were issued restricts, among other
things, our ability to:

  .  incur debt;

  .  create levels of debt that are senior to the notes but junior to our
     senior debt;

  .  pay dividends on or redeem capital stock;

  .  make some investments or redeem other subordinated debt;

  .  make particular dispositions of assets;

  .  engage in transactions with affiliates;

  .  engage in particular business activities; and

  .  engage in mergers, consolidations and particular sales of assets.

   The indenture provides for acceleration of payments under the senior
subordinated discount notes upon customary events of default, including cross
defaults, judgment defaults and events of bankruptcy.

Vendor Financing

   In May 1998, we entered into a vendor procurement contract with Lucent,
under which we agreed to purchase radio, call connecting and related equipment
and services for the development of our network. We also entered into a note
purchase agreement with Lucent under which Lucent agreed to provide us with
$80.0 million of junior subordinated vendor financing. This $80.0 million
consisted of $40.0 million aggregate principal amount of increasing rate Lucent
series A notes and $40.0 million aggregate principal amount of increasing rate
Lucent series B notes.

   We borrowed $40.0 million under the series B note facility and repaid this
amount and accrued interest of $227,778 in April 1999 from proceeds of our sale
of senior subordinated discount notes. This amount cannot be reborrowed. As of
September 30, 1999, we had outstanding approximately $42.5 million of our
Lucent series A notes, including $1.6 million of Lucent series A notes issued
as payment of interest in kind, plus $0.9 million of additional accrued
interest and accruing interest at a rate per annum of 8.5% as of September 30,
1999. Proceeds from the sale of these notes have been used to develop our
network in designated areas. The Lucent series A notes as amended mature in
October 2009 and amounts outstanding under these series A notes and any future
series A note borrowings are subject to mandatory prepayment in an amount equal
to 50% of the excess of $198.0 million in net proceeds we receive from an
equity offering other than this offering and the concurrent offering and the
issuance of capital stock used to acquire related businesses or assets.

   In October 1999 we entered into an amended and restated note purchase
agreement with Lucent under which Lucent has agreed to purchase up to $12.5
million of new series A notes and up to $12.5 of new series B notes under a
vendor expansion facility in connection with our prior acquisition of licenses
in the San Juan, Puerto Rico, Evansville Indiana, Paducah, Kentucky and
Alexandria and Lake Charles, Louisiana markets. The obligation of Lucent to
purchase notes under this vendor expansion facility is subject to a number of
conditions, including that we commit to purchase one wireless call connection
equipment site and 50 network equipment sites for each additional market from
Lucent.

   In addition, pursuant to the amended and restated note purchase agreement
Lucent has agreed to make available up to an additional $50.0 million of new
vendor financing not to exceed an amount equal to 30% of the value of
equipment, software and services provided by Lucent in connection with any
additional markets we acquire. This $50.0 million of availability is subject to
a reduction up to $20 million on a dollar for dollar basis of any additional
amounts Lucent otherwise lends to us for such purposes under our senior credit
facilities. Any notes purchased under this facility would be divided equally
between Lucent series A and series B notes.

   The terms of Lucent series A and series B notes issued under these expansion
facilities would be identical to the terms of the original Lucent series A and
series B notes as amended, including a maturity date of October 23, 2009.

   In addition, any Lucent series B notes issued under the vendor expansion
facility will mature and will be subject to mandatory prepayment on a dollar
for dollar basis out of the net proceeds of any future public or private
offering or sale of debt securities, exclusive of any private placement of
notes issued to finance any additional markets and borrowings under the senior
credit facilities or any replacement facility.

   Lucent series A notes, including any Lucent series A notes issued under the
vendor expansion facility, initially accrue interest at a rate of 8.5% per
annum. If the Lucent series A notes are not redeemed in full on or prior to
January 1, 2001, the rate will increase by 1.5% per annum on each January 1
thereafter, beginning January 1, 2001, provided that the maximum interest rate
will not exceed 12 1/8%. Interest on the Lucent series A notes will be payable
semi-annually, provided that prior to May 11, 2004, interest will be payable in
additional Lucent series A notes and subsequently will be payable in cash,
unless prohibited by the senior credit facilities or the indenture.

                                       93
<PAGE>

   Any Lucent series B notes issued under the vendor expansion facility will
initially accrue interest at a rate of 10% per annum. If the Lucent series B
notes are not redeemed in full on or prior to January 1, 2000, the rate will
increase by 1.5% per annum on each January 1 beginning on January 1, 2000,
provided that the maximum interest rate will not exceed 12 1/8%. Interest on
the Lucent series B notes will be payable semi-annually, provided that prior to
May 11, 2004, interest will be payable in additional Lucent series B notes and
subsequently will be payable in cash unless prohibited by the terms of the
senior credit facilities or the indenture.

   Upon a change of control, we must offer to repay the Lucent series A and
series B notes at their principal amount plus a premium, unless prohibited by
our senior credit facilities or the senior subordinated notes indenture. In the
event a change of control occurs prior to May 1, 2002 in the case of the Lucent
series A notes, or in the case of the Lucent series B notes, May 1, 2000, the
Company may elect to prepay all of the Lucent series A or series B notes in
accordance with the optional prepayment provisions, but that such time
restrictions do not apply to any notes held by Lucent or its affiliates. The
Lucent Series A and Series B notes may not be prepaid, however, if prohibited
by the terms of the senior credit facilities, the senior subordinated notes
indenture or other indebtedness that ranks senior to the Lucent series A and
series B notes.

   The Lucent series A notes may be prepaid without payment of a premium at any
time prior to May 1, 2002. In addition, the Lucent series A notes may be
prepaid at any time after May 1, 2002 without payment of a premium to the
extent Lucent or its affiliates have retained them. The Lucent series B notes
may be prepaid without payment of a premium at any time prior to May 1, 2000.
In addition, the Lucent series B notes may be prepaid at any time after May 1,
2000 without payment of a premium to the extent Lucent or its affiliates have
retained them. We cannot redeem the series A Notes that Lucent has assigned or
participated to a third party from May 1, 2002 through April 30, 2007 and any
redemption thereafter will require the payment of a premium. We cannot redeem
the series B Notes that Lucent has assigned or participated to a third party
from May 1, 2000 through April 30, 2005 and any redemption thereafter will
require the payment of a premium. The premiums decrease in each year after the
first year in which the premiums first become payable. The Lucent series A and
series B Notes may not be prepaid, however, if prohibited by the terms of our
senior credit facilities, the senior subordinated notes indenture or other
indebtedness that ranks senior to the Lucent series A and series B Notes.

   If Lucent has not completed specified resales in respect of the Lucent
series A or series B notes then outstanding prior to January 1, 2003, we must
pay Lucent up to 3% of the then outstanding principal amount of all the Lucent
series A and series B notes to defray any actual marketing distribution and
other costs incurred by Lucent in connection with any resales of series A and
series B notes.

Government Debt

   In connection with our purchase of our licenses, we issued to the FCC
secured installment payment plan notes in an aggregate principal amount of $9.2
million. This debt is shown on our balance sheet at a value of $8.0 million
reflecting a discount of $1.2 million reflecting the below market interest rate
on the debt. The FCC notes are due April 28, 2007, and bear interest at a rate
of 6.25% per annum. In addition, we assumed $4.1 million in aggregate principal
amount of additional secured installment payment plan notes in connection with
the Digital PCS acquisition. This debt is shown on our balance sheet at a value
of $3.0 million reflecting a discount of $1.1 million reflecting the below
market interest rate on the debt. The Digital PCS notes are due August 21,
2007, and bear interest at a rate of 6.125% per annum. In connection with the
Wireless 2000 acquisition, we assumed $7.4 million in aggregate principal
amount of additional secured installment payment plan notes. This debt is shown
on our balance sheet at a value of $6.1 million reflecting a discount of $1.3
million reflecting the below market interest rate on the debt. The Wireless
2000 notes are due September 17, 2006, and bear interest at a rate of 7.0% per
annum. A security agreement secures the FCC notes, Wireless 2000 notes and
Digital PCS notes, which grants the FCC a first priority security interest in
the license for which the applicable note was issued. In the event of a default
under the FCC notes, Wireless 2000 notes or Digital PCS notes, the FCC may
revoke the licenses for which the defaulted notes were issued.

    .  3,090 shares of voting preference common stock

    .  200,000 shares of series B preferred stock

    .  215,000 shares of series C preferred stock

    .  50,000 shares of series D preferred stock

    .  30,000 shares of series E preferred stock

    .  15,450,000 shares of series F preferred stock

    .  1,000,000 undesignated shares

   As of September 30, 1999 our outstanding capital stock consisted of:

    .  73,835,264 shares of class A voting common stock

    .  283,813 shares of class C common stock

    .  851,429 shares of class D common stock

    .  49,417 shares of series D preferred stock

    .  24,980 shares of series E preferred stock

    .  14,912,778 shares of series F preferred stock

   Subject to any required approval of holders of any shares of any class or
series of preferred stock, our board has the power, by resolution, to issue
additional shares of preferred stock with the preferences, rights and
designations as it determines.

Voting Rights

   Subject to the rights of specific classes of stock to vote as a class on
some matters, regardless of the number of shares outstanding, the holders of
the class A common stock are entitled to an aggregate 4,990,000 votes and the
holders of voting preference common stock are entitled to an aggregate
5,010,000 votes of all outstanding capital stock. Each holder of class A common
stock shall have the number of votes equal to 4,990,000 divided by the number
of outstanding shares of class A common stock multiplied by the number of
shares of class A common stock held by such stockholder. No other class of
capital stock has the right to vote on any matter except as required by law. In
addition, for so long as AT&T and its affiliates continue to hold at least two-
thirds of the shares of series A preferred stock they held as of May 14, 1999,
they will be entitled, but not obliged, to nominate one of our directors.


                                       95
<PAGE>

   Our restated certificate of incorporation that will become effective upon
closing of this offering provides that, except where a class of capital stock
has the right to vote as a class, a quorum will be present so long as a
majority of the outstanding voting preference common stock and shares
representing at least 5,010,000 votes are present. When a class vote is
required, a majority of that class must also be present. Any further action not
requiring a class vote may be approved by the affirmative vote of a majority of
voting preference common stock present at any meeting where a quorum is
present.
   The holders of each class of preferred stock have the right to vote as a
class on any measure to:

  .  authorize or issue any shares senior to or on a parity with the class;

  .  amend our restated certificate of incorporation to change any of the
     characteristics of the class; or

  .  authorize or issue any security convertible into, exchangeable for or
     granting the right to purchase or otherwise receive any shares of stock
     senior to or on a parity with the class.

   The majority of each class of preferred stock must affirmatively vote to
act.

   Subject to any class voting requirements, shares of common stock
representing at least two-thirds of the votes entitled to be cast for the
election of our directors must affirmatively vote for any amendment, alteration
or repeal of our certificate of incorporation or bylaws, unless any amendment,
alteration or repeal is proposed and declared advisable by our board, in which
case only the affirmative vote of a majority of these shares is required.

   If:

  .  we receive an opinion of regulatory counsel that class A common stock
     and voting preference common stock can vote and be treated as a single
     class of stock for quorum purposes and have one vote per share;

  .  not less than two-thirds of the outstanding class A common stock
     affirmatively vote for the single class status; and

  .  our board determines that it is not likely to be detrimental to us,

we will seek the approval of the FCC to have class A common stock and voting
preference common stock vote and be treated together as a single class with one
vote per share.

   Some of our stockholders have entered into agreements regarding the voting
of their shares on particular matters, including the election of directors.
These agreements include the stockholders' agreement and the investors
stockholders' agreement among our initial investors and the management
stockholders. See "Certain Relationships and Related Transactions--AT&T
Agreements."

Conversion

   After July 17, 2006, holders of series A preferred stock may convert their
shares into shares of class A common stock at a conversion rate equal to the
liquidation preference of series A preferred stock divided by the market price
of class A common stock.

   If we receive an opinion of regulatory counsel that class A common stock and
voting preference common stock can vote and be treated as a single class of
stock with one vote per share, then, unless our board determines that it is
likely to be detrimental to us, holders of class C common stock and class D
common stock may convert their shares into shares of class A common stock or
class B common stock upon the affirmative vote of the holders of 66 2/3% or
more of the class A common stock. We expect that in 2004, the FCC ownership
restrictions will no longer apply to us, allowing regulatory counsel to deliver
this opinion.

                                       96
<PAGE>

   At any time, holders of series F preferred stock may convert each share into
one share of class A or class B common stock; provided, that, until the class C
common stock and class D common stock is convertible into class A common stock
as set forth in the preceding paragraph, the first 195,063 of these shares to
be converted are convertible into shares of class D common stock.

   At any time, holders of class A common stock and class B common stock may
convert their shares into shares of the other class.

   All conversions are subject to obtaining any required FCC approvals. Holders
of preferred or common stock may elect to convert any or all of their shares by
giving written notice to us prior to the requisite FCC approvals. This
conversion will not become effective until the final receipt of all necessary
FCC approvals.

Redemption

   We have the right to redeem our capital stock as follows:

  .  shares of series A preferred stock: following 30 days after the 10th
     anniversary of issuance at the liquidation preference of the series A
     preferred stock;

  .  shares of series B preferred stock: at any time at the liquidation
     preference of the series B preferred stock; and

  .  shares of series C preferred stock and series D preferred stock: at any
     time at the liquidation preferences of series C preferred stock and
     series D preferred stock; provided, that if we redeem any shares of
     either series C preferred stock or series D preferred stock, we must
     redeem a proportionate number of shares of the other.

   In addition, the holders of some classes of capital stock have the right to
require us to redeem their shares as follows:

  .  holders of series A preferred stock or series B preferred stock:
     following the 30th day after the 20th anniversary of issuance at the
     liquidation preference of the series A preferred stock or series B
     preferred stock; and

  .  holders of series C preferred stock, series D preferred stock or series
     E preferred stock: following the 30th day after the 20th anniversary of
     issuance at the liquidation preference of the series C preferred stock,
     series D preferred stock and series E preferred stock.

   Neither we nor any holder of shares of any class of our capital stock may
cause us to redeem our capital stock if, at that time:

  .  we are insolvent or will be rendered insolvent by the redemption; or

  .  law or any of our agreements prohibits the redemption.

   Further, our restated certificate of incorporation restricts our ability to
redeem any shares of capital stock to the extent shares of capital stock
ranking senior to or on a parity with the shares remain outstanding or
dividends on the senior or parity shares have not been paid in full.

   Our restated certificate of incorporation also provides for our redemption
of any shares of our capital stock that is held by stockholders whose holding
of the shares, in the opinion of our board, may result in the loss of, or
failure to obtain the reinstatement of, any of our licenses or franchises.

   The management agreement provides for the redemption by us of specific
shares of class A common stock and series E preferred stock held by Mr. Vento
and Mr. Sullivan in particular circumstances. See "Management--Management
Agreement."

Dividends

preferred stock or series B preferred stock are outstanding, no dividends may
be paid on any shares of any class of capital stock ranking junior to series A
preferred stock or series B preferred stock. Dividends accrue from the date of
issuance of the shares and are payable quarterly, provided that we have the
option to defer payments for up to ten and one-half years from the date of
issuance.

   Subject to the rights of the holders of the preferred stock, our board may
declare dividends on the common stock; provided, that dividends on class C
common stock and class D common stock may only be paid up to the amount by
which funds legally available for the dividends exceed the excess of:

  (1) fair market value of the assets of TeleCorp Holding less TeleCorp
     Holding's liabilities over

  (2) the aggregate par value of class C common stock and class D common
     stock, at our board's discretion.

   Dividends may only be paid on the other classes of common stock up to the
amount legally available after subtracting the maximum amount payable in
respect of class C common stock and class D common stock, at our board's
discretion.

   We may not pay dividends on any shares of any class of our capital stock if,
at the time:

  .  we are insolvent or will be rendered insolvent by the payments; or

  .  law or any of our agreements prohibits the dividend payments.

   Further, our restated certificate of incorporation restricts our ability to
pay any dividends on any class of capital stock to the extent shares of capital
stock ranking senior to or on a parity with the class remain outstanding or
dividends on the senior or parity shares have not been paid in full.

Liquidation Preference

   The holders of preferred stock are entitled to preferences with respect to
distributions upon our liquidation, dissolution or winding up as follows:

  .  holders of series A preferred stock and series B preferred stock are
     entitled to a preference per share equal to $1,000 plus accrued and
     unpaid dividends on the shares;

  .  holders of series C preferred stock are entitled to a preference per
     share equal to the paid-in capital per share of series C preferred stock
     together with interest on $1,000 from the date of issuance at a rate of
     6% per annum, compounded quarterly, less the amount of any dividends
     paid on the share, plus accrued and unpaid dividends;

  .  holders of series D preferred stock are entitled to a preference per
     share equal to $1,000 together with interest from the date of issuance
     at rate of 6% per annum, compounded quarterly, less the amount of any
     dividends paid on the share, plus accrued and unpaid dividends;

  .  holders of series E preferred stock are entitled to a preference per
     share equal to the amount of accrued and unpaid dividends on the share,
     together with interest on $1,000 from the date of issuance at a rate of
     6% per annum, compounded quarterly, less the amount of any dividends
     declared and paid on the share; and

  .  holders of series F preferred stock are entitled to a preference equal
     to $.000032 plus accrued and unpaid dividends on the shares.

   Following payment of all amounts payable to the holders of preferred stock
upon our liquidation, dissolution or winding up, the holders of class C common
stock and class D common stock will be entitled to receive the fair market
value of the assets of TeleCorp Holding less TeleCorp Holding's liabilities.
The holders of the other classes of common stock will be entitled to receive
the remaining amounts available for distribution.

Transfer Restriction

   Some of our stockholders have entered into agreements that restrict transfer
of their shares and provide for the happening of specified events, such as
share conversions. See "Certain Relationships and Related Transactions--AT&T
Agreements" and "--Management Agreement."

   Our restated certificate of incorporation provides that, upon the happening
of specified events described in the stockholders' agreement, we have the right
to exchange all or some of the shares of series A preferred stock, series D
preferred stock, series F preferred stock and common stock held by AT&T for an
equal number of shares of series B preferred stock. See "Certain Relationships
and Related Transactions--AT&T Agreements."

Anti-Takeover Effects of Certain Provisions of Delaware Law and our Amended and
Restated Certificate of Incorporation and Bylaws

   We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Generally, Section 203 prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the interested
stockholder attained that status with the approval of the board of directors or
unless the business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to the interested stockholder. Generally, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within three years did own, 15% or more of a corporation's voting stock. This
statute could prohibit or delay the accomplishment of mergers or other
takeovers or changes in control with respect to us and, accordingly, may
discourage attempts to acquire us.

                                      100
<PAGE>

   In addition, provisions of our restated certificate of incorporation and
bylaws, which provisions will be in effect upon the closing of the offering and
are summarized in the following paragraphs, may be deemed to have an anti-
takeover effect. These provisions may delay, defer or prevent a tender offer or
takeover attempt that a stockholder might consider to be in its best interest,
including those attempts that might result in a premium over the market price
for the shares held by stockholders.

   Nomination and Election of Directors. Our restated certificate of
incorporation provides that following completion of this offering, our nine
member board of directors will be divided into three classes of directors. Each
class will serve a staggered three-year term where one-third of the board of
directors will be elected each year. In general, this means that a director
will stand for election only once every three years. The classified board
provision could have the effect of discouraging a third party from making a
tender offer or otherwise attempting to obtain control of us, even though the
attempt might be beneficial to us and our stockholders. In addition, the
classified board provision could delay the stockholders who do not agree with
the policies of the board from removing a majority of the board for two years.

   Board of Directors Removal and Vacancies. Our restated certificate of
incorporation provides that directors may be removed only for cause and only by
the affirmative vote of the holders of a majority of the outstanding shares of
voting stock cast, at an annual or special meeting, except that any director
nominated by any holder of our preferred stock having the right to nominate
such director may be removed and replaced by such holder with or without cause.
In addition, our bylaws authorize the board of directors to fill vacant
directorships or increase the size of the board of directors except that any
vacancy that was left by a nominee of a stockholder entitled to nominate the
nominee will be filled by a new director selected by the holder, subject to any
required approvals. This may prevent a stockholder from removing incumbent
directors and simultaneously gaining control of the board of directors by
filling the resulting vacancies created by such removal with its own nominees.

   Special Meetings of Stockholders. Our bylaws provide that special meetings
of our stockholders may be called only by the Chairman, the President or a
majority of the board of directors or stockholders holding 35% of our
outstanding voting shares.

   Authorized But Unissued Shares. The authorized but unissued shares of common
stock and preferred stock are available for future issuance without stockholder
approval, subject to the limitations imposed by the Nasdaq National Market.
These additional shares may be used for a variety of corporate purposes,
including future public offerings to raise additional capital, corporate
acquisitions and employee benefit plans. The existence of authorized but
unissued and unreserved common stock and preferred stock could render more
difficult or discourage an attempt to obtain control of us by means of a proxy
contest, tender offer, merger or otherwise.

   Amendment to Our Certificate of Incorporation. Amendments to our restated
certificate of incorporation which are not proposed by our board must be
approved by the affirmative vote of at least two-thirds of our outstanding
shares of capital stock entitled to vote in the election of directors. Any
amendment proposed by the board requires only the minimum vote required by law
or any applicable terms of our capital stock. Our bylaws may be amended in the
same manner as our restated certificate of incorporation or, alternatively, by
a majority vote of our board of directors.

   Stockholder Proposals. The bylaws require that stockholders wishing to bring
any business, including the nomination of directors, before an annual meeting
of stockholders, deliver written notice to us not less than 90 days prior to
the date of the annual meeting of stockholders. If, however, the date of the
meeting is scheduled to occur more than 30 days before or more than 90 days
after the anniversary of the prior year's annual meeting, notice by the
stockholder must be delivered to us not later than the close of business on the
tenth day following the day on which we publicly announce the date of our
annual meeting. The foregoing provisions regarding director nomination
procedures do not apply to holders of our capital stock who have the right to
nominate directors under our stockholders' agreement or restated certificate of
incorporation. These provisions may discourage or make more difficult the
acquisition of control of us by means of a tender offer, open market purchase,
proxy contest or otherwise.

                                      101
<PAGE>

   The Delaware General Corporation Law provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation, or bylaws,
unless a corporation's certificate of incorporation or bylaws, as the case may
be, requires a greater percentage.

Indemnification of Directors and Executive Officers and Limitation of
Liability

   Our restated certificate of incorporation includes a provision that
eliminates the personal liability of our directors and executive officers for
monetary damages for breach of fiduciary duty as a director or executive
officer, except:

  .  for any breach of the director's or executive officer's duty of loyalty
     to us or our stockholders;

  .  for acts or omissions not in good faith or that involve intentional
     misconduct or a knowing violation of law;

  .  for unlawful dividends and stock purchases under the Delaware General
     Corporation Law; or

  .  for any transaction from which the director derived an improper personal
     benefit.

   Our bylaws provide that:

  .  we must indemnify our directors and officers to the fullest extent
     permitted by Delaware law, subject to very limited exceptions;

  .  we may indemnify our other employees and agents to the same extent that
     we indemnify our officers and directors, unless otherwise required by
     law, our amended and restated certificate of incorporation, our bylaws
     or agreements; and

  .  we must advance expenses, as incurred, to our directors and executive
     officers in connection with any legal proceeding to the fullest extent
     permitted by Delaware law, subject to limited exceptions.

   We have entered into indemnity agreements with each of our directors and
executive officers to give them additional contractual assurances regarding
the scope of the indemnification described above and to provide additional
procedural protections. In addition, we have obtained directors' and officers'
insurance providing indemnification for our directors, officers and key
employees for various liabilities. We believe that these indemnification
provisions and agreements are necessary to attract and retain qualified
directors and officers.

   The limitation of liability and indemnification provisions in our restated
certificate of incorporation and bylaws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary duty. These
provisions may also have the effect of reducing the likelihood of stockholder
derivative litigation against directors and officers, even though a derivative
action, if successful, might otherwise benefit us and our stockholders.
Furthermore, a stockholder's investment may be adversely affected to the
extent we pay the costs of settlement and damage awards against directors and
officers under these indemnification provisions.

   At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees for which indemnification is sought, nor
are we aware of any threatened litigation that my result in claims for
indemnification.

Transfer Agent and Registrar

   The transfer agent and registrar for our class A common stock is State
Street Bank and Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no public market for our class A
common stock. As described below, only a limited number of shares will be
available for sale shortly after this offering due to contractual and legal
restrictions on resale. Sales of substantial amounts of our class A common
stock in the public market after the restrictions lapse or are waived could
cause the market price of our class A common stock to drop significantly.

   Upon completion of this offering and the concurrent offering to AT&T
Wireless, we will have outstanding an aggregate of 85,023,889 shares of class A
common stock assuming no exercise of the underwriters' over-allotment option,
or the purchase by AT&T Wireless of additional shares in connection with such
exercise, and no exercise of outstanding options. Of these shares, all of the
shares sold in this offering, other than shares sold to some of our existing
stockholders, will be freely tradable without restriction or further
registration under the Securities Act. The remaining class A common shares held
by existing shareholders are "restricted securities" as that term is defined in
Rule 144 under the Securities Act. These shares are eligible for public sale
only if registered under the Securities Act or sold under an exemption to
registration under the Securities Act. There are also contractual restrictions
on some of the holders of these shares which restrict their ability to sell the
shares.

   The following table summarizes approximately when the 77,223,889 shares of
class A common stock that constitute either restricted securities or securities
held by affiliates will be eligible for sale into the public market:

</TABLE>

   These rules and contractual restrictions governing the shares' eligibility
for public sale are as follows:

Rule 144

   In general, under Rule 144 as currently in effect, beginning January 11,
2000, 90 days after we became subject to reporting requirements under the
Securities Exchange Act of 1934, a person who has beneficially owned class A
common stock for at least one year would be entitled to sell within any three-
month period a number of shares that does not exceed the greater of:

  .  1% of the number of class A common shares then outstanding, which will
     equal approximately850,239 class A common shares immediately after this
     offering and the concurrent offering; or

  .  the average weekly trading volume of the class A common shares on the
     Nasdaq National Market during the four calendar weeks preceding the
     filing of a notice of Form 144 with respect to such sale.

   Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us.

                                      103
<PAGE>

Rule 144(k)

   Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell these shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Unless
otherwise restricted, these shares may be sold immediately upon the completion
of this offering.

Rule 701

   As of October 18, 1999, we have granted to our employees and certain
directors and officers options to purchase an aggregate of 552,505 shares of
class A common stock, of which options to purchase 75,844 of class A common
stock had vested.

   In general, under Rule 701, any of our employees, directors, officers,
consultants or advisors who purchase class A common shares from us in
connection with a compensatory stock or option plan or other written agreement
before the effective date of this offering is entitled to resell these shares
after January 11, 2000, 90 days after we became subject to reporting
requirements under the Securities Exchange Act of 1934, in reliance on Rule
144, without having to comply with certain restrictions, including the holding
period contained in Rule 144.

   The SEC has indicated that Rule 701 will apply to typical stock options
granted by an issuer before it becomes subject to the reporting requirements of
the Securities Exchange Act of 1934, along with the shares acquired upon
exercise of these options, including exercises after the date of this
prospectus. Securities issued in reliance on Rule 701 are restricted securities
and, subject to the contractual restrictions described below, may be sold:

   .  after January 11, 2000;

   .  by persons other than affiliates subject only to the manner of sale
provisions of Rule 144; and

  .  by affiliates under Rule 144 without compliance with its one year
     minimum holding period requirement.

Lock-up Agreements

   Our executive officers, directors, other key employees and our initial
investors have signed lock-up agreements under which they agreed not to dispose
of or hedge any capital stock or any securities convertible into or
exchangeable for capital stock for a period of 180 days from the date of this
prospectus.

Stock Options

   Following the completion of this offering, we intend to file a registration
statement on Form S-8 under the Securities Act covering the shares of class A
common shares reserved for issuance under our stock option plan and other
options issued to our employees, directors and officers. We expect the
registration statement to be filed soon after the date of this prospectus and
automatically to become effective upon filing. Accordingly, class A common
stock registered under the registration statement will, subject to vesting
provisions and volume limitations under the Securities Act applicable to our
affiliates, be available for sale in the open market immediately, or, in the
case of certain directors and other key employees, immediately after the 180-
day lock-up agreements expire.

Registration Rights

   Commencing on the first anniversary of the completion of this offering,
stockholders beneficially holding 86,037,089 shares of class A common stock
prior to completion of this offering are entitled to request that we register
their shares of class A common stock under the Securities Act. AT&T Wireless
will also have such rights with respect to the shares of class A common stock
they purchase in the concurrent offering. After these shares are registered,
they will become freely tradable without restriction under the Securities Act.
However, under the stockholders' agreement, these stockholders have agreed not
to transfer their shares until at least July 17, 2001.

               MATERIAL U.S. TAX CONSEQUENCES TO NON-U.S. HOLDERS

   Following is a general discussion of material U.S. federal income and estate
tax consequences of the ownership and disposition of the class A common stock
applicable to non-U.S. holders of class A common stock. For purposes of this
discussion, a non-U.S. holder is any holder of class A common stock that, for
U.S. federal income tax purposes, is not a U.S. person. This discussion does
not address all aspects of U.S. federal income and estate taxation that may be
relevant in light of a non-U.S. holder's particular facts and circumstances,
such as being a U.S. expatriate, and does not address any tax consequences
arising under the laws of any state, local or non-U.S. taxing jurisdiction.
Furthermore, the following discussion is based on current provisions of the
Internal Revenue Code of 1986, as amended, and administrative and judicial
interpretations thereof, all as in effect on the date hereof, and all of which
are subject to change, possibly with retroactive effect. We have not and will
not seek a ruling from the Internal Revenue Service with respect to the U.S.
federal income and estate tax consequences described below, and as a result,
there can be no assurance that the Internal Revenue Service may disagree with
or challenge any of the conclusions set forth in this discussion.

   For purposes of this discussion, the term U.S. person means:

  .  a citizen or resident of the United States;

  .  a corporation, partnership or other entity created or organized in the
     United States or under the laws of the United States or any political
     subdivision thereof;

  .  an estate whose income is included in gross income for U.S. federal
     income tax purposes regardless of its source; or

  .  a trust whose administration is subject to the primary supervision of a
     U.S. court and which has one or more U.S. persons who have the authority
     to control all substantial decisions of the trust.

Dividends

   A dividend paid to a non-U.S. holder generally will be subject to U.S.
withholding tax either at a rate of 30% of the gross amount of the dividend or
such lower rate as may be specified by an applicable income tax treaty.
Dividends received by a non-U.S. holder that are effectively connected with a
U.S. trade or business conducted by the non-U.S. holder are exempt from that
withholding tax. However, those effectively connected dividends, net of certain
deductions and credits, are taxed at the same graduated rates applicable to
U.S. persons.

   In addition to the graduated tax described above, dividends received by a
corporate non-U.S. holder that are effectively connected with a U.S. trade or
business of the corporate non-U.S. holder may also be subject to a branch
profits tax at a rate of 30% or such lower rate as may be specified by an
applicable income tax treaty.

   A non-U.S. holder that is eligible for a reduced rate of withholding tax
pursuant to an applicable income tax treaty may be required to submit
documentation to avail itself of that treaty and may be able to obtain a refund
of any excess amounts withheld by us by filing an appropriate claim for refund
with the Internal Revenue Service.

Gain on Disposition of Class A Common Stock

   A non-U.S. holder generally will not be subject to U.S. federal income tax
on any gain realized upon the sale or other disposition of class A common stock
unless:

  .  the gain is effectively connected with a U.S. trade or business of the
     non-U.S. holder, which gain, in the case of a corporate non-U.S. holder,
     must also be taken into account for branch profits tax purposes;

                                      105
<PAGE>

  .  the non-U.S. holder is an individual who holds his or her class A common
     stock as a capital asset, which generally means as an asset held for
     investment purposes, and who is present in the United States for a
     period or periods aggregating 183 days or more during the calendar year
     in which the sale or disposition occurs and certain other conditions are
     met; or

  .  We are or we have been a United States real property holding corporation
     for U.S. federal income tax purposes at any time within the shorter of
     the five-year period preceding the disposition or the holder's holding
     period for its class A common stock. We believe that we are not and will
     not become a United States real property holding corporation for U.S.
     federal income tax purposes.

Backup Withholding and Information Reporting

   Generally, we would be required to report annually to the Internal Revenue
Service the amount of dividends, if any, paid on the class A common stock, the
name and address of the recipient, and the amount, if any, of tax withheld. A
similar report would be sent to the recipient. Pursuant to applicable income
tax treaties or other agreements, the Internal Revenue Service may make its
reports available to tax authorities in the recipient's country of residence.

   Dividends paid to a non-U.S. holder at an address within the United States
may be subject to backup withholding at a rate of 31% if the non-U.S. holder
fails to establish that it is entitled to an exemption or to provide a correct
taxpayer identification number and other information to the payer. Backup
withholding will generally not apply to dividends paid to non-U.S. holders at
an address outside the United States on or prior to December 31, 2000 unless
the payer has knowledge that the payee is a U.S. person. Under the recently
finalized Treasury Regulations regarding withholding and information
reporting, payment of dividends to non-U.S. holders at an address outside the
United States after December 31, 2000 may be subject to backup withholding at
a rate of 31% unless such non-U.S. Holder satisfies various certification
requirements.

   Under current treasury regulations, the payment of the proceeds of the
disposition of class A common stock to or through the U.S. office of a broker
is subject to information reporting and backup withholding at a rate of 31%
unless the holder certifies its non-U.S. status under penalties of perjury or
otherwise establishes an exemption. Generally, the payment of the proceeds of
the disposition by a non-U.S. holder of class A common stock outside the
United States to or through a foreign office of a broker will not be subject
to backup withholding but will be subject to information reporting
requirements if the broker is:

  .  a U.S. person;

  .  a controlled foreign corporation for U.S. federal income tax purposes;
     or

  .  a foreign person 50% or more of whose gross income for certain periods
     is from the conduct of a U.S. trade or business

unless the broker has documentary evidence in its files of the holders' non-
U.S. status and certain other conditions are met, or the non-U.S. holder
otherwise establishes an exemption. Neither backup withholding nor information
reporting generally will apply to a payment of the proceeds of a disposition
of class A common stock by or through a foreign office of a foreign broker not
subject to the preceding sentence.

   In general, the recently finalized treasury regulations, described above,
do not significantly alter substantive withholding and information reporting
requirements but would alter procedures for claiming benefits of an income tax
treaty and change the certifications procedures relating to the receipt by
intermediaries of payments on behalf of the beneficial owner of shares of
class A common stock. Non-U.S. holders should consult their tax advisors
regarding the effect, if any, of those final treasury regulations on an
investment in the class A common stock. Those final treasury regulations are
generally effective for payments made after December 31, 2000.


                                      106
<PAGE>

   Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the Internal
Revenue Service.

Estate Tax

   An individual non-U.S. holder who owns class A common stock at the time of
his or her death or had made certain lifetime transfers of an interest in class
A common stock will be required to include the value of that class A common
stock in his or her gross estate for U.S. federal estate tax purposes, unless
an applicable estate tax treaty provides otherwise.

   The foregoing discussion is a summary of the principal U.S. federal income
and estate tax consequences of the ownership, sale or other disposition of
class A common stock by non-U.S. holders. Accordingly, investors are urged to
consult their own tax advisors with respect to the income and estate tax
consequences of the ownership and disposition of class A common stock,
including the application and effect of the laws of any state, local, foreign
or other taxing jurisdiction.

</TABLE>

Of the 9,200,000 shares of our class A common stock being offered by this
prospectus, 1,610,000 shares will be offered to some of our existing
stockholders.

   The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of various legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the shares, other than those
covered by the over-allotment option described below, if they purchase any of
the shares. The underwriters have agreed to reimburse us for certain of our
expenses.

   The underwriters, for whom Salomon Smith Barney Inc., Lehman Brothers Inc.,
Deutsche Bank Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith
Incorporated are acting as representatives, propose to offer some of the shares
directly to the public at the public offering price listed on the cover page of
this prospectus and some of the shares to various dealers at the public
offering price less a concession not in excess of $0.81 per share. The
underwriters may allow, and these dealers may reallow, a concession not in
excess of $0.10 per share on sales to other dealers. If all of the shares are
not sold at the initial offering price, the representatives may change the
public offering price and the other selling terms. The representatives have
advised us that the underwriters do not intend to confirm any sales to any
accounts over which they exercise discretionary authority.

   We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to 1,380,000 additional shares of
class A common stock at the public offering price less the underwriting
discount. The underwriters may exercise their option solely for the purpose of
covering over-allotments, if any, in connection with this offering. To the
extent this option is exercised, each underwriter will be obligated, subject to
various conditions, to purchase a number of additional shares approximately
proportionate to its initial purchase commitment.

   The price of the shares to be sold to AT&T Wireless in the concurrent
offering is expected to be equal to the initial public offering price per share
less an amount equal to the underwriting discount we pay to the underwriters in
this offering. The underwriters will not receive any compensation in connection
with the concurrent offering.

   At our request, the underwriters will reserve up to approximately 390,000
shares of class A common stock to be sold, at the initial public offering
price, to our directors, officers and employees and their friends and family
members. This directed share program will be administered by Merrill Lynch,
Pierce, Fenner & Smith Incorporated. The number of shares of common stock
available for sale to the general public will be reduced to the extent these
individuals purchase reserved shares. Any reserved shares which are not so
purchased will be offered by the underwriters to the general public on the same
basis as the other shares offered hereby.

   Our executive officers, directors, other key employees and initial investors
have agreed that, for a period of 180 days from the date of this prospectus,
they will not, without the prior written consent of Salomon Smith

                                      108
<PAGE>

Barney Inc., dispose of any of our capital stock, or any securities convertible
into or exchangeable for our capital stock, except for shares of our class A
common stock acquired in the public market following the offering by persons
other than our officers and directors.

   We have also agreed with the underwriters that, for a period of 180 days
from the date of this prospectus, we will not, without the prior written
consent of Salomon Smith Barney Inc., issue or sell any shares of our class A
common stock, or any securities convertible into or exchangeable for our class
A common stock, provided, however, that we may issue class A common stock in
exchange for outstanding securities convertible or exercisable into our class A
common stock, under certain stock awards to our employees and directors and in
connection with certain acquisitions.

   Prior to this offering, there has been no public market for the class A
common stock. Consequently, the initial public offering price for the shares
was determined by negotiations between us and the representatives. Among the
factors considered in determining the initial public offering price were our
record of operations, our current financial condition, our future prospects,
our markets, the economic conditions in and future prospects for the industry
in which we compete, our management, and currently prevailing general
conditions in the equity securities markets, including current market
valuations of publicly traded companies considered comparable to us. We cannot
assure you, however, that the prices at which the shares will sell in the
public market after this offering will not be lower than the price at which
they are sold by the underwriters or that an active trading market in the class
A common stock will develop and continue after this offering.

   The following table shows the underwriting discounts and commissions we must
pay to the underwriters in connection with this offering. These amounts are
shown assuming both no exercise and full exercise of the underwriters' option
to purchase additional shares of class A common stock to cover over-allotments.

   We have agreed to indemnify the underwriters against various liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

   In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may over-allot, or engage in syndicate covering transactions,
stabilizing transactions and penalty bids. Over-allotment involves syndicate
sales of class A common stock in excess of the number of shares to be purchased
by the underwriters in the offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of the class A common stock
made for the purpose of preventing or retarding a decline in the market price
of the class A common stock while the offering is in progress. Penalty bids
permit the underwriters to reclaim a selling concession from a syndicate member
when Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member. These activities may cause the price of the class A common stock to be
higher than the price that would otherwise would exist in the open market in
the absence of these transactions. These transactions may be effected on the
Nasdaq national market or in the over-the-counter market, or otherwise and, if
commenced, may be discontinued at any time.

   Deutsche Bank Securities Inc. and Lehman Brothers Inc. have performed
investment banking and advisory services for us from time to time for which
they have received customary compensation and reimbursement of expenses. Among
other services, they have acted as underwriters and arrangers for our senior
subordinated discount notes offering and as agents and lenders under our senior
credit facilities.

communications laws.

                       Report of Independent Accountants

To the Board of Directors and Stockholders
TeleCorp PCS Inc. and Subsidiaries and Predecessor Company:

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, changes in stockholders' equity
(deficit) and cash flows present fairly, in all material respects, the
financial position of TeleCorp PCS Inc. and Subsidiaries and Predecessor
Company (the Company) at December 31, 1997 and 1998 and September 30, 1999 and
the consolidated results of their operations and their cash flows for the
period July 29, 1996 (date of inception) to December 31, 1996, for the years
ended December 31, 1997 and 1998 and for the nine month period ended September
30, 1999, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

                                 ------------

   The consolidated financial statements and the Notes have been adjusted to
give effect to the stock split as described in Note 16.

1. Organization

   TeleCorp Holding Corp., Inc. (Holding) was incorporated in the State of
Delaware on July 29, 1996 (date of inception). Holding was formed to
participate in the Federal Communications Commission's (FCC) Auction of F-Block
Personal Communications Services (PCS) licenses (the Auction) in April 1997.
Holding successfully obtained licenses in the New Orleans, Memphis, Beaumont,
Little Rock, Houston, Tampa, Melbourne and Orlando Basic Trading Areas (BTAs).
Holding qualifies as a Designated Entity and Very Small Business under Part 24
of the rules of the FCC applicable to broadband PCS.

   In April 1997, Holding entered into an agreement to transfer the PCS
licenses for the Houston, Tampa, Melbourne and Orlando BTAs to four newly-
formed entities created by Holding's existing stockholder group: THC of
Houston, Inc.; THC of Tampa, Inc.; THC of Melbourne, Inc.; and THC of Orlando,
Inc. These licenses were transferred along with the related operating assets
and liabilities in exchange for investment units consisting of Class A, B and C
common stock and Series A preferred stock in August 1997. Concurrently, Holding
distributed the investment units, on a pro rata basis, in a partial stock
redemption to Holding's existing stockholder group and issued an aggregate of
approximately $2.7 million in affiliate notes payable (see Note 5) to the
newly-formed entities. As a result of this distribution, Holding no longer
retains any ownership equity interest in the newly-formed entities. Because the
above transaction was non-monetary in nature and occurred between entities with
the same stockholder group, the transaction was accounted for at historical
cost (see Note 14).

   TeleCorp PCS, Inc. (TeleCorp) was incorporated in the State of Delaware on
November 14, 1997 by the controlling stockholders of Holding. TeleCorp will be
the exclusive provider of wireless mobility services in its licensed regions in
connection with a strategic alliance with AT&T Corporation and its affiliates
(collectively AT&T). Upon finalization of the AT&T Transaction, Holding became
a wholly-owned subsidiary of TeleCorp (see Note 6).

   TeleCorp has various wholly-owned subsidiaries which includes TeleCorp
Communications, Inc., TeleCorp LLC and Holding. TeleCorp receives services from
TeleCorp Management Corp., an affiliate company owned by two officers and
stockholders of TeleCorp (see Note 14).

2. Summary of Significant Accounting Policies

 Basis of presentation

   Holding was formed to explore various business opportunities in the wireless
telecommunications industry. TeleCorp was formed to continue the activity of
Holding through its strategic alliance with AT&T. Since inception, Holding's
and TeleCorp's activities have consisted principally of hiring a management
team, raising capital, negotiating strategic business relationships,
participating in the Auction and operating wireless networks. Consequently, for
purposes of the accompanying financial statements, Holding has been treated as
a "predecessor" entity. Therefore, the financial statements as of December 31,
1997 and for the period July 29, 1996 to December 31, 1996 and for the year
ended December 31, 1997 include the historical financial information of
Holding, the predecessor entity. The financial statements as of and for the
year ended December 31, 1998 and for all periods thereafter, include the
historical financial information of Holding and TeleCorp. The Chief Executive
Officer and President of Holding maintain the positions of Chief Executive
Officer and Executive Vice President and Chief Financial Officer, respectively,
of TeleCorp. In addition, these

officers own a majority of the voting stock of TeleCorp and, prior to the
finalization of the AT&T Transaction, owned a majority of the voting stock of
Holding. As a result of this relationship, certain financing relationships and
the similar nature of business activities, Holding and TeleCorp are considered
companies under common control. Therefore, the accompanying financial
statements incorporate the combined business activities of Holding and
TeleCorp. Collectively, TeleCorp and Holding are referred to as the Company in
the accompanying consolidated financial statements.

 Unaudited Interim Financial Information

   The unaudited consolidated statements of operations and cash flows for the
nine months ended September 30, 1998, and related footnotes, have been prepared
in accordance with generally accepted accounting principles for interim
financial information and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles. In the opinion of management, the interim data includes
all adjustments (consisting of only normal recurring adjustments) necessary for
a fair statement of the results for the interim period.

 Consolidation

   The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries, which includes TeleCorp Communications,
Inc., TeleCorp LLC and Holding. All intercompany accounts and transactions have
been eliminated in consolidation. For the nine months ended September 30, 1999,
the Company has consolidated the results of Viper Wireless, Inc. since the
Company's absence of voting control is considered temporary (see Notes 7 and
17).

 Development Stage Company

   Prior to January 1, 1999, the Company's activities principally have been
planning and participation in the Auction, initiating research and development,
conducting market research, securing capital and developing its proposed
service and network. Since the Auction, the Company has been relying on the
borrowing of funds and the issuance of common and preferred stock rather than
recurring revenues, for its primary sources of cash flow. Accordingly, the
Company's financial statements for all periods prior to January 1, 1999 were
presented as a development stage enterprise, as prescribed by Statement of
Financial Accounting Standards No. 7, "Accounting and Reporting by Development
Stage Enterprises." In the first quarter of 1999, the Company commenced
operations in the New Orleans, Memphis and Little Rock BTA's and began
providing wireless mobility services for its customers. As a result, the
Company exited the development stage in the quarter ended March 31, 1999.

   The Company incurred cumulative losses through September 30, 1999 of
approximately $199,000,000. The Company expects to continue to incur
significant operating losses and to generate negative cash flow from operating
activities for at least the next several years while it constructs its network
and develops its customer base. The Company's ability to eliminate operating
losses and to generate positive cash flow from operations in the future will
depend upon a variety of factors, many of which it is unable to control. These
factors include: (1) the cost of constructing its network, (2) changes in
technology, (3) changes in governmental regulations, (4) the level of demand
for wireless communications services, (5) the product offerings, pricing
strategies and other competitive factors of the Company's competitors and (6)
general economic conditions. If the Company's is unable to implement its
business plan successfully, it may not be able to eliminate operating losses,
generate

positive cash flow or achieve or sustain profitability which would materially
adversely affect its business, operations and financial results as well as its
ability to make payments on its debt obligations.

 Fair Value of Financial Instruments

   The Company believes that the carrying amount of its financial instruments
approximate fair value.

 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 on the date of the financial
statements and the reported amounts of expenses during the reporting period.
Actual results could differ from those estimates.

 Concentration of Credit Risk

   Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents.
The Company has invested its excess cash in overnight sweep accounts and U.S.
Treasury obligations. The Company has not experienced any losses on its cash
and cash equivalents.

 Cash Equivalents

   The Company considers all highly liquid instruments with a maturity from
purchase date of three months or less to be cash equivalents. Cash equivalents
consist of overnight sweep accounts and U.S. Treasury obligations.

 Revenue Recognition

   The Company earns revenue by providing wireless mobility services to both
its subscribers and subscribers of other wireless carriers traveling in the
Company's service area, as well as sale of equipment and accessories.

   Wireless mobility services revenue consists of monthly service fees,
activation fees, airtime and long distance revenue. Generally, access fees,
airtime and long distance charges are billed monthly and are recognized when
service is provided. Prepaid service revenue is collected in advance, is
recorded as deferred revenue and recognized as service is provided.

   Roaming revenue consists of the airtime and long distance charged to the
subscribers of other wireless carriers for use of the Company's network while
traveling in the Company's service area and is recognized when the service is

   Equipment revenue is recognized upon delivery of the equipment to the

 PCS Licenses and Microwave Relocation Costs

   PCS licenses include costs incurred, including capitalized interest related
to the U.S. Government financing, to acquire FCC licenses in the 1850-1990 MHz
radio frequency band. Interest capitalization on the

U.S. Government financing began when the activities necessary to get the
Company's network ready for its intended use were initiated and concluded when
the wireless networks were ready for intended use. The PCS licenses are issued
conditionally for ten years. Historically, the FCC has granted license renewals
providing the licensees have complied with applicable rules, policies and the
Communications Act of 1934, as amended. The Company believes it has complied
with and intends to continue to comply with these rules and policies.

   As a condition of each PCS license, the FCC requires each license-holder to
relocate existing microwave users (Incumbents) within the awarded spectrum to
microwave frequencies of equal capacity. Microwave relocation costs include the
actual and estimated costs incurred to relocate the Incumbent's microwave links
affecting the Company's licensed frequencies.

   PCS licenses, microwave relocation costs, and capitalized interest consist
of the following:

   The Company began amortizing the cost of the PCS licenses, microwave
relocation costs, and capitalized interest in March 1999, when PCS services
commenced in certain BTAs. Amortization is calculated using the straight-line
method over 40 years. Amortization expense for the nine months ended September
30, 1999 was $1,716,091.

 Property and Equipment and Network Under Development

   Property and equipment are recorded at cost and depreciation is computed
using the straight-line method over the following estimated useful lives:

   Expenditures for repairs and maintenance are charged to operations when
incurred. Gains and losses from disposals, if any, are included in the
statements of operations. Network under development includes all costs related
to engineering, cell site acquisition, site development, interest expense and
other development costs being incurred to ready the Company's wireless network
for use.

   Internal and external costs incurred to develop the Company's billing,
financial systems and other internal applications during the application
development stage are capitalized as internal use software. All costs incurred
prior to the application development stage are expensed as incurred. Training
costs and all post implementation internal and external costs are expensed as
incurred.

 Intangible assets--AT&T Agreements

   The AT&T Agreements consist of the fair value of various agreements with
AT&T (see Note 6) exchanged for mandatorily redeemable preferred stock and
Series F preferred stock (see notes 6 and 7). The AT&T Agreements are amortized
on a straight-line basis over the related contractual terms, which range from
three to ten years. Amortization on the AT&T Exclusivity Agreement, Long
Distance Agreement and the Intercarrier Roamer Services Agreement began once
wireless services were available to its customers. Amortization of the Network
Membership License Agreement began on July 17, 1998, the date of the
finalization of the AT&T Transaction. During 1999, the Company completed
acquisitions for additional licenses (see Note 7).

 Inventory

   Inventory consists of the following:

Inventory is valued at the lower of cost or market and is recorded net of an
allowance for obsolescence. No allowance for obsolescence has been recorded as
of December 31, 1998 and September 30, 1999.

 Deferred Financing Costs

   In connection with entering into the credit facility and the senior-
subordinated discount rates (see Note 5), the Company incurred certain debt
issuance costs. The Company has capitalized financing costs of $9,109,677 and
$20,108,970, as of December 31, 1998 and September 30, 1999, respectively. The
financing costs are being amortized using the straight line method over the
term of the credit facility. For the year ended December 31, 1998 and for the
nine months ended September 30, 1999, the Company recorded interest expense
related to the amortization of the deferred financing costs of $524,924 and
$1,199,642, respectively.

 Long-Lived Assets

   The Company periodically evaluates the recoverability of the carrying value
of property and equipment, network under development, intangible assets, PCS
licenses and microwave relocation costs. The Company considers historical
performance and anticipated future results in its evaluation of potential
impairment. Accordingly, when indicators of impairment are present, the Company
evaluates the carrying value of these assets in relation to the operating
performance of the business and future and undiscounted cash flows expected to
result from the use of these assets. Impairment losses are recognized when the
sum of the present value of expected future cash flows are less than the
assets' carrying value. No such impairment losses have been recognized to date.

 Income Taxes

   The Company accounts for income taxes in accordance with the liability
method. Deferred income taxes are recognized for tax consequences in future
years for differences between the tax bases of assets and

liabilities and their financial reporting amounts at each year-end, based on
enacted laws and statutory tax rates applicable to the periods in which the
differences are expected to affect taxable income. Valuation allowances are
established, when necessary, to reduce net deferred tax assets to the amount
expected to be realized. The provision for income taxes consists of the current
tax provision and the change during the period in deferred tax assets and
liabilities.

 Start-Up and Advertising Costs

   Start-up costs are expensed as incurred. The Company expenses production
costs of print, radio and television advertisements and other advertising costs
as such costs are incurred. Advertising expenses in selling and marketing for
1996, 1997, and 1998 were insignificant. Advertising expenses in selling and
marketing were $9,331,592 for the nine months ended September 30, 1999.

 Interest Rate Swaps

   The Company uses interest swaps to hedge the effects of fluctuations in
interest rates from their Senior Credit Facility (see Note 5). These
transactions meet the requirements for hedge accounting, including designation
and correlation. The interest rate swaps are managed in accordance with the
Company's policies and procedures. The Company does not enter into these
transactions for trading purposes. The resulting gains or losses, measured by
quoted market prices, are accounted for as part of the transactions being
hedged, except that losses not expected to be recovered upon the completion of
hedged transactions are expensed. Gains or losses associated with interest rate
swaps are computed as the difference between the interest expense per the
amount hedged using the fixed rate compared to a floating rate over the term of
the swap agreement. As of December 31, 1998, the Company has entered into six
interest rate swap agreements with various commercial lenders totaling a
notional amount of $225,000,000 to convert the Company's variable rate debt of
LIBOR plus 3.25% to fixed rate debt. The six outstanding interest rate swap
contracts fix LIBOR at annual interest rates from 5.20% to 5.26%. The contracts
mature in September of 2003. The interest rate swaps had no material impact on
the consolidated financial statements as of and for the year ended December 31,
1998 and as of and for the nine months ended September 30, 1999.

 Segment Reporting

   The Company presently operates in a single business segment as a provider of
wireless mobility services in its licensed regions primarily in the south-
central and northeastern United States. The Company operates in various MTAs
including New Orleans, LA, Memphis, TN, Little Rock, AK, Boston, MA and Puerto
Rico.

 Stock Compensation

   The Company periodically issues restricted stock awards to its employees.
Upon reaching a measurement date, the Company records deferred compensation
equal to the estimated fair value of the stock award. Deferred compensation is
amortized to compensation expense over the related vesting period.

 Recently Issued Accounting Standards

   In July 1999, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 137, "Deferral of the Effective
Date of FAS 133" which defers the effective date of SFAS No. 133, "Accounting
for Derivative Instruments and Hedging Activities". SFAS 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 2000. The Company
has not determined the effect of adopting this standard.

 Net Loss Attributable to Common Equity Per Share and Pro Forma Net Loss
 Attributable to Common Equity Per Share

   The Company computes net loss attributable to common equity per share in
accordance with SFAS No. 128, "Earnings Per Share," and SEC Staff Accounting
Bulletin No. 98 (SAB 98). Under the provisions of SFAS No. 128 and SAB 98,
basic net loss attributable to common equity per share is computed by dividing
the net loss attributable to common equity for the period by the weighted
average number of common equity shares outstanding during the period, which
includes Series F Preferred Stock and all classes of Common Stock. Diluted net
loss attributable to common equity per share is computed by dividing the net
loss attributable to common equity for the period by the weighted average
number of common and dilutive common equivalent shares outstanding during the
period. As the Company had a net loss attributable to common equity in each of
the periods presented, basic and diluted net loss attributable to common
equity per share are the same. Pro forma basic and diluted net loss
attributable to common equity per share has been calculated assuming the
completion of our pending acquisitions of Telecorp LMDS, Inc., the
finalization of the share issuance of Viper Wireless, Inc. (see Note 17) and
the completed acquisitions (see Note 7) as if these acquisitions were in
effect in the periods presented. As the Company had a net loss attributable to
common equity in each of the periods presented, pro forma basic and diluted
net loss attributable to common equity per share is the same.

printing, legal and accounting fees totaled $10,999,293. The Notes mature April
15, 2009, unless previously redeemed by the Company. As interest accrues, it
will be added to the principal as an increase to interest expense and the
carrying value of the Notes until April 15, 2004. The Company will begin paying
interest semi-annually on April 15 and October 15 of each year beginning
October 15, 2004. The Notes are not collateralized. The Notes

principal was $16,716,212.

 Senior Credit Facilities

   In July 1998, the Company entered into a credit facility (the Senior Credit
Facility) with a group of commercial lenders, under which the Company may
borrow up to $525,000,000, in the aggregate, consisting of (i) up to
$150,000,000 in revolving loans (the Senior Revolving Credit Facility) with a
maturity date of January 2007, (ii) a $150,000,000 term loan (the Tranche A
Term Loan) with a maturity date of January 2007, and (iii) a $225,000,000 term
loan (the Tranche B Term Loan) with a maturity date of January 2008. A total of
$225,000,000 of indebtedness from the Tranche B Term Loan was outstanding as of
December 31, 1998 and September 30, 1999. The Senior Credit Facility also
provides for an uncommitted $75,000,000 senior term loan (the Expansion
Facility) with a maturity date of January 2008.

   Beginning in September 2002, principal repayments will be made in 18
quarterly installments for the Tranche A Term Loan and 22 quarterly
installments for the Tranche B Term Loan. Quarterly principal repayments for
the Tranche A Term Loan are as follows: first six, $3,750,000; next four,
$9,375,000; last eight, $11,250,000. Quarterly principal repayments for the
Tranche B Term Loan are as follows: first 18, $562,500, last four, $53,718,750.
Interest payments on the senior credit facility are made quarterly. The Senior
Credit Facility contains a prepayment provision whereby certain amounts
borrowed must be repaid upon the occurrence of certain specified events.

   The commitment to make loans under the Tranche A Term loan will terminate in
July 2001, or earlier if elected by the Company. Beginning in April 2005, the
commitment to make loans under the Senior Revolving Credit Facility will be
permanently reduced on a quarterly basis through April 2007 as follows: first
four reductions, $12,500,000; last four reductions $25,000,000. The unpaid
principal on the Senior Revolving Credit Facility is due January 2007. In July
2000, if the undrawn portion of the Tranche A Term Loan exceeds $50,000,000 the
amount of the Tranche A Term Loan will be automatically reduced by such excess.

   The interest rate applicable to the Senior Credit Facility is based on, at
the Company's option, (i) LIBOR (Eurodollar Loans) plus the Applicable Margin,
as defined, or (ii) the higher of the administrative agent's prime rate or the
Federal Funds Effective Rate (ABR Loans), plus the Applicable Margin, as
defined. The Applicable Margin for Eurodollar Loans will range from 125 to 325
basis points based upon certain events by the Company, as specified. The
Applicable Margin for ABR Loans will range from 25 to 225 basis points based
upon certain events by the Company, as specified. At December 31, 1998, the
interest rate applicable to the Tranche B Term Loan was 8.75% and interest
incurred for the year ended December 31, 1998 was $9,210,187 of which
$7,710,187 was expensed and $1,500,000 was capitalized. At September 30, 1999,
the interest rate applicable to the Tranche B Term Loan was 8.48%, and for the
nine months ended September 30, 1999 interest incurred on the Tranche B Term
Loan was $14,093,750 of which $9,615,395 was expensed and $4,478,355 was
capitalized.

   The loans from the Senior Credit Facility are subject to an annual
commitment fee which ranges from 0.50% to 1.25% of the available portion of the
Tranche A Term Loan and the Senior Revolving Credit Facility. The Company has
expensed $3,305,905 and $2,863,252, for the year ended December 31, 1998 and
for the nine months ended September 30, 1999, respectively, related to these
bank commitment fees. The Senior Credit Facility requires the Company to
purchase interest rate hedging contracts covering amounts equal to at least

50% of the total amount of the outstanding indebtedness of the Company. As of
December 31, 1998 and September 30, 1999, the Company hedged 100% of its
outstanding indebtedness of $225,000,000 to take advantage of favorable
interest rate swaps. The six outstanding interest rate swap contracts fix LIBOR
at annual interest rates from 5.20% to 5.26%. The contracts mature in September
of 2003.

   Initially, borrowings under the Senior Credit Facility are subject to a
maximum Senior Debt to Total Capital ratio, as defined, of 50%. This ratio is
increased to 55% if certain specified operating benchmarks are achieved. In
addition, the Company must comply with certain financial and operating
covenants. The financial covenants include various debt to equity, debt to
EBITDA, interest coverage, and fixed charge coverage ratios, as defined in the
Senior Credit Facility. The operating covenants include minimum subscribers,
minimum aggregate service revenue, minimum coverage of population and maximum
capital expenditure thresholds. As of December 31, 1998 and September 30, 1999,
the Company was in compliance with these covenants.

   The Company may utilize the Expansion Facility as long as the Company is not
in default of the Senior Credit Facility and is in compliance with each of the
financial covenants. However, none of the lenders are required to participate
in the Expansion Facility.

   The Senior Credit Facility is collateralized by substantially all of the
assets of the Company. In addition, the Senior Credit Facility has been
guaranteed by the Company's subsidiaries and shall be guaranteed by
subsequently acquired or organized domestic subsidiaries of the Company.

 Lucent Note Agreements

   In May 1998, the Company entered into a Note Purchase Agreement (the Lucent
Note Agreement) with Lucent Technologies, Inc. (Lucent) which provides for the
issuance of increasing rate 8.5% Series A (the Series A Notes) and 10.0% Series
B (the Series B Notes) junior subordinated notes (the Subordinated Notes) with
an aggregate face value of $80,000,000. The aggregate face value of the
Subordinated Notes shall decrease dollar for dollar, upon the occurrence of
certain events as defined in the Lucent Note Agreement. The proceeds of the
Subordinated Notes are to be used to develop the Company's network in certain
designated areas. As of December 31, 1998, the Company had $10,460,400
outstanding under the Series A Notes. As of September 30, 1999, the Company had
$42,515,924 outstanding under the Series A Notes. During the nine months ended
September 30, 1999, the Company borrowed and repaid $40,000,000 on the Lucent
Series B Notes plus $227,778 of accrued interest. Interest expense for the year
ended December 31, 1998 and for the nine months ended September 30, 1999 was
$460,000 and $2,283,302, respectively.

   The Series A and Series B Notes will not amortize and will have a maturity
date six months after the final maturity of the Company's high yield debt
offering, but in no event later than May 1, 2012. The Series A Notes will have
a mandatory redemption at par plus accrued interest from the proceeds of a
subsequent equity offering to the extent the net proceeds exceed an amount
identified in the Lucent Note Agreement. If the Series A Notes and Series B
Notes are not redeemed in full by January 2001 and January 2000, respectively,
the interest rate on each note will increase by 1.5% per annum on January 1.
However, the interest rate applicable to the Subordinated Notes shall not
exceed 12.125%. Interest payable on the Series A Notes and the Series B Notes
on or prior to May 11, 2004 shall be payable in additional Series A and Series
B Notes. Thereafter, interest shall be paid in arrears in cash on each six
month and yearly anniversary of the Series A and Series B closing date or, if
cash interest payments are prohibited under the Senior Credit Facility and/or
the Senior Subordinated Discount Notes, in additional Series A and Series B
Notes. As of December 31, 1998 and September 30, 1999, interest accrued under
the Series A Notes of $460,400 and $2,515,924, respectively has been included
in long-term debt.

   The Company may redeem the Subordinated Notes held by Lucent or any of its

premium, as specified. All of the outstanding notes under the Lucent Note
Agreement as of December 31, 1998 and September 30, 1999 are held by Lucent.
The Company must comply with certain operating covenants. As of December 31,
1998 and September 30, 1999, the Company was in compliance with these operating
covenants.

 U.S. Government financing

   As of December 31, 1998 and September 30, 1999, the Company owes the U.S.
Government $9,192,938 and $20,519,972, less a discount of $1,268,272 and
$2,637,037, respectively, for the acquisition of PCS licenses in New Orleans,
Memphis, Beaumont and Little Rock obtained during the 1997 F-Block auction. The
terms of the notes include: an interest rate of 6.25%, quarterly interest
payments which commenced in July 1998 and continue for the one year thereafter,
then quarterly principal and interest payments for the remaining 9 years. The
promissory notes are collateralized by the underlying PCS licenses.

   During the nine months ended September 30, 1999, the Company completed the
acquisition of additional PCS licenses from Digital PCS, LLC and Wireless 2000,
Inc. (see Note 7). As part of these acquisitions, the Company assumed
additional U.S. Government financing with the FCC amounting to $11,550,645,
less a discount of $1,630,562. The terms of the notes include an interest rate
of 6.125% for notes assumed from Digital PCS, LLC and 7.00% for notes assumed
from Wireless 2000, Inc., quarterly interest payments for a two-year period and
then quarterly principal and interest payments for the remaining eight years.

   The notes were discounted using management's best estimate of the prevailing
market interest rate at the time of issuance of 10.25%.

 Notes payable to stockholders

   In July 1996, the Company issued $498,750 of subordinated promissory notes
to two stockholders. The notes bore interest at a rate of 10%, compounded semi-
annually, and were due in full in July 2002. In April 1997, these notes were
converted into 50 shares of Series A preferred stock.

   In December 1997, the Company issued various promissory notes totaling
$2,808,500 to stockholders. The notes bore interest at a rate of 6% and were
converted into mandatorily redeemable preferred stock of the Company in July
1998. The notes were discounted using management's best estimate of the
prevailing market interest rate at the time of issuance of 10.25%. The effect
on the Company's 1997 financial statements of discounting these notes was not
material.

   From January 1, 1998 to June 30, 1998, the Company borrowed approximately
$22,491,500 in the form of promissory notes from existing and prospective
stockholders to satisfy the working capital needs of the Company. The
promissory notes bore interest at the rate of 6.25% per annum compounded
quarterly and were payable in one lump sum on August 31, 1998. In July 1998,
these notes were converted to mandatorily redeemable preferred stock of the
Company (see Note 11) in connection with the AT&T Transaction.

6. AT&T Transaction

   In January 1998, the Company entered into a Securities Purchase Agreement
(the Securities Purchase Agreement) with AT&T Wireless PCS, Inc. and TWR
Cellular, Inc. (both subsidiaries of AT&T Corporation and collectively referred
to as AT&T PCS), the stockholders of Holding and various venture capital
investment firms (the Cash Equity Investors). The Securities Purchase Agreement
provides the Company will be a provider of wireless mobility services in its
licensed regions utilizing the AT&T brand name.

   Upon the receipt of FCC approval in July 1998, the Company finalized the
transaction contemplated in the Securities Purchase Agreement (the AT&T
Transaction). As a result, the Company (i) issued preferred stock and paid AT&T
$21,000,000 in exchange for 20 MHz PCS licenses with a fair value of
$94,850,000 and certain operating agreements with AT&T for exclusivity, network
membership, long distance and roaming with a fair value of $27,050,000; (ii)
issued preferred and common stock for 100% of the outstanding ownership
interests in Holding, which includes 10 MHz PCS licenses which was recorded at
historical cost; and (iii) issued preferred and common stock for a cash
commitment from the Cash Equity Investors of $128,000,000 to be paid over a
three year term (see Note 11) plus an additional $5,000,000 upon the closing of
the Digital PCS, Inc. transaction (see Note 7).

   The general terms of the operating agreements with AT&T are summarized
below:

  .  AT&T Exclusivity: The Company will be AT&T's exclusive facilities-based
     provider of mobile wireless telecommunications services within the
     Company's BTAs for an initial ten year period. This agreement will
     automatically renew for a one-year term and then operate on a year-to-
     year basis unless one party terminates at least ninety (90) days prior
     to the end of any one-year term.

     The Company has determined the fair value of this agreement to be
     $11,870,000 and is amortizing this value over the initial 10 year term.

  .  Network Membership License Agreement: The Network Membership License
     Agreement (the License Agreement) defines that AT&T will make available
     to the Company use of the AT&T logo and the right to refer to itself as
     a "Member of the AT&T Wireless Network" to market its PCS services.
     Through the use of these rights, the Company expects to participate in
     and benefit from AT&T promotional and marketing efforts. The License
     Agreement has an initial five-year term with a five-year renewal term if
     both the Company and AT&T elect to renew at least ninety 90 days prior
     to the expiration of the initial term.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                                 ------------


     The Company has determined the fair value of this agreement to be
     $8,480,000 and is amortizing this value over the initial five year term.

  .  Intercarrier Roamer Services Agreement: AT&T and the Company have
     entered into a twenty-year reciprocal roaming agreement provided that
     their customers who own tri-mode phones will roam on the other's mobile
     wireless systems at commercially reasonable rates to the extent
     commercially and technologically feasible. Thereafter, this agreement
     shall renew automatically on a year-to-year basis unless either the
     Company or AT&T terminates this agreement by written notice at least 90
     days prior to the conclusion of the original or any subsequent term.
     After ten years, this agreement may be terminated by the Company or AT&T
     at any time upon 90 days prior written notice.

     The Company has determined the value of this roaming agreement to be
     $3,500,000 and is amortizing this value over the initial 10 year term.

  .  Long Distance Agreement: The long distance agreement provides that AT&T
     will be the exclusive provider for long distance services to the
     Company's customers within the Company's licensed regions for an initial
     three year period. The long distance agreement requires that the Company
     meet a minimum traffic volume commitment during the term of the
     agreement. If the Company fails to meet such volume commitments, the
     Company must pay to AT&T the difference between the expected fee based
     on the volume of the commitment and the fees based on actual volume.

     The Company had determined the fair value of this agreement to be
     $3,200,000 and is amortizing this value over the initial three year
     term.

   Triton PCS, Inc. (Triton), Tritel Communications (Tritel), and the Company
have adopted a common brand, SunCom, which is co-branded with equal emphasis
with the AT&T brand name and logo. On April 16, 1999, Triton, Tritel and
TeleCorp Communications formed a new company, Affiliate License Co., L.L.C., to
own, register and maintain the marks SunCom, SunCom Wireless and other SunCom
and Sun formative marks (SunCom Marks) and to license the SunCom marks to
Triton, Tritel and the Company. Triton, Tritel and TeleCorp Communications each
have a 33% membership interest in Affiliate License Co., L.L.C. On April 16,
1999, Triton entered into an agreement to settle a potential dispute regarding
prior use of the SunCom brand. In connection with this settlement, Triton
agreed to pay $975,000 to acquire the SunCom Marks which were contributed to
Affiliate License Co., L.L.C. The Company paid $325,000 in royalty payments to
reimburse Triton for the contributed SunCom marks.

7. Acquisitions

   On April 20, 1999, the Company completed the acquisition of 10 MHz PCS
licenses covering the Baton Rouge, Houma, Hammond and Lafayette, Louisiana
BTA's from Digital PCS, LLC. The total purchase price of $6,113,889 was
comprised of $2,334,819 of mandatorily redeemable preferred stock and common
stock of the Company, the assumption of U.S. Government financing with the FCC
of $4,101,455, less a discount of $608,941, and $286,556 in cash as

Equity Investors have irrevocably committed to contribute $5,000,000 in
exchange for mandatorily redeemable preferred stock and common stock over a two
year period from the close of this transaction. As of September 30, 1999 the
Company has received $2,200,000 of the $5,000,000 commitment.

   As a result of completing this transaction, the Company's available
borrowings under the Lucent Note Agreement (see Note 5) increased by
$15,000,000 ($7,500,000 of Series A and $7,500,000 of Series B) and certain
Cash Equity Investors committed $39,996,600 in cash in exchange for mandatorily
redeemable preferred and common stock. The Cash Equity Investors cash
commitment of $39,996,600 will be funded over a three year period from the
close of this transaction. As of September 30, 1999, the Company received
$11,998,980 of this cash commitment. As a part of obtaining this additional
preferred and common stock financing, the Company paid $2,000,000 to a Cash
Equity Investor upon the closing of the transaction. In addition, certain
officers, the Chief Executive Officer and the Executive Vice President and
Chief Financial Officer of the Company were issued fixed and variable awards of
5,318 and 2,380,536 restricted shares of mandatorily redeemable Series E
preferred stock and Class A common stock, respectively, in exchange for their
interest in Puerto Rico Acquisition Corporation. Puerto Rico Acquisition
Corporation was a special purpose entity wholly-owned by the Company's Chief
Executive Officer and Executive Vice President and Chief Financial Officer. The
fixed awards typically vest over a five-year period. The estimated fair value
of these shares has been recorded as deferred compensation and is being
amortized over the related vesting periods. The variable awards vest based upon
certain future events taking place, such as build-out milestone POP coverage,
the completion of our initial public offering and other events. Upon the
occurrence of these future events, the Company will remeasure the variable
awards and record compensation expense, deferred compensation and additional
paid-in-capital.

   On June 2, 1999 the Company acquired from Wireless 2000, Inc. 15 MHz PCS
licenses in the Alexandria, Lake Charles and Monroe, Louisiana BTAs. The total
purchase price of $7,448,318 was comprised of $370,810 of mandatorily
redeemable preferred stock and common stock of the Company, the assumption of
U.S. Government financing with the FCC of $7,449,190, less a discount of
$1,021,621, and $649,939 in cash as reimbursement of microwave relocation costs
and reimbursement of FCC interest and legal costs. The entire purchase price
has been allocated to the PCS licenses acquired.

   In February 1999, Viper Wireless, Inc. (Viper), was formed to participate in
the C-Block PCS license reauction for additional spectrum in most of the
Company's markets. Viper was initially capitalized for $100 and was equally-
owned by the Company's Chief Executive Officer and Executive Vice President-
Chief Financial Officer. In order to participate in the reauction, the Company
paid the FCC an initial deposit of $17,818,549, on behalf of Viper.
Simultaneously, the Company transferred this initial deposit to Viper in
exchange for an 85% ownership interest which represented a 49.9% voting
interest.

   On April 15, 1999, the FCC announced Viper was the high bidder for 15 MHz
licenses in New Orleans, Houma and Alexandria, Louisiana, San Juan, Puerto Rico
and Jackson, Tennessee and 30 MHz licenses in Beaumont, Texas. The total
auction price is $32,286,000 plus legal fees of $46,566. During the nine months
ended September 30, 1999, the FCC refunded $11,361,351 of the initial deposit;
however, the Company was required to pay the FCC $11,059,194 as a final deposit
on behalf of Viper. As of and for the nine months ended September 30, 1999,
Viper had no financial activity other than its capitalization which includes
the transfer of the initial deposit to Viper. The Company received final
regulatory approval of the license transfer from the FCC on September 9, 1999.
The entire purchase price has been allocated to the PCS licenses acquired.

   AT&T and certain of the Company's other stockholders have committed an
aggregate of up to approximately $32,300,000 in exchange for additional shares
of mandatorily redeemable preferred stock, Series F preferred stock and common
stock of the Company. As part of this financing, the Company paid approximately
$500,000 to an affiliate of a Cash Equity Investor for closing this preferred
and common stock financing. In May and July 1999, AT&T and the certain Cash
Equity Investors funded approximately $17,516,000 of their commitment to the
Company. The Company made its final payment of $14,769,600 to the FCC on
September 13, 1999 with respect to these licenses and received the remaining
funding commitments from AT&T and the certain Cash Equity Investors on
September 29, 1999.

8. Mandatorily Redeemable Preferred Stock and Stockholders' Equity

 Holding

   Holding's authorized capital stock consisted of 6,000 shares of no par value
mandatorily redeemable Series A preferred stock, 125,000 shares of no par value
Class A common stock, 175,000 shares of no par value Class B common stock and
175,000 shares of no par value Class C common stock. This capital stock was in
existence during 1996, 1997, and through July 1998, the closing of the AT&T
Transaction, at which time Holding became a wholly-owned subsidiary of the
Company. Subsequent to the AT&T Transaction, the authorized and outstanding
shares of Holding were cancelled and replaced with 1,000 authorized shares of
common stock of which 100 shares were issued to the Company.

9. Restricted Stock Plan

   In July 1998, the Company adopted a Restricted Stock Plan (the Plan) to
attract and retain key employees and to reward outstanding performance. Key
employees selected by management may elect to become participants in the Plan
by entering into an agreement which provides for issuance of fixed and variable
units consisting of Series E mandatorily redeemable preferred stock and Class A
common stock. The fixed units typically vest over a five or six year period.
The variable units vest based upon certain events taking place, such as
buildout milestones, Pop coverage, the completion of an initial public offering
and other events. Unvested shares are forfeited upon termination of employment.
The shares issued under the Plan shall consist of units transferred to
participants without payment as additional compensation for their services to
the Company. The total number of units that may be awarded to key employees
shall not exceed 7,085 units or a defined number of shares of Series E
preferred stock and Class A common stock, respectively, as determined upon
award. Any units not granted on or prior to July 17, 2003 shall be awarded to
two officers of the Company. Each participant has voting, dividend and
distribution rights with respect to all shares of both vested and unvested
common stock. Prior to the Class A shares becoming publicly traded, the Company
retains the right of first offer to buy the employees' vested shares at the
offer price. After the Class A shares become publicly traded, the right of
first offer will no longer exist for the Series E preferred shares. In addition
the shares contain rights of inclusion and first negotiation. The Company may
repurchase unvested shares, and under certain circumstances, vested shares of
participants whose employment with the Company terminates. The repurchase price
is equal to $0.01 and $0.00003 per share for the Series E preferred and common
stock, respectively.

10. Employee and Director Stock Option Plan

   On July 22, 1999, the Company implemented the 1999 Stock Option Plan to
allow employees and members of the Board of Directors to acquire shares of
Class B common stock. The options will have an option term of 10 years, ratable
vesting over a three to four year period, exercise prices equal to the
estimated fair value of the underlying Class B common stock on the date of
award and restrictions on exercisability until (i) a qualified initial public
offering (IPO) to which the Class A voting common stock has been registered
under the Securities Act of 1933 for aggregate proceeds of $20,000,000, (ii)
the sale of all or substantially all of the assets of the Company or (iii) the
sale of all or substantially all of the outstanding capital stock of the
Company. The Company has reserved 1,814,321 shares of Class A common stock for
issuance under this plan.

   On July 22, 1999, the Company granted 552,505 stock options at an exercise
price of $.0065 per share. The stock options awarded during the nine month

   For federal income tax purposes, start-up costs are being amortized over
five years starting January 1, 1999 when active business operations commenced.
As of September 30, 1999, the Company had approximately $161 million of net
operating losses. The net operating losses will begin to expire in 2017. There
may be a limitation on the annual utilization of net operating losses and
capitalized start-up costs as a result of certain ownership changes that have
occurred since the Company's inception. A valuation allowance is recognized if,
based on the weight of available evidence, it is more likely than not that some
portion or all of the deferred tax asset will not be realized. Based on the
Company's financial results, management has concluded that a full valuation
allowance for all of the Company's deferred tax assets is appropriate.

13. Commitments

   In May 1998, the Company entered into a vendor procurement contract (the
Vendor Procurement Contract) with Lucent, pursuant to which the Company may
purchase up to $285,000,000 of radio, switching and related equipment and
services for the development of the Company's wireless communications network.
Through December 31, 1998 and September 30, 1999, the Company has purchased
approximately $90,900,000 and $194,500,000, respectively, of equipment and
services from Lucent since the inception of the Vendor Procurement Contract.

   The Company has operating leases primarily related to retail store
locations, distribution outlets, office space, and rent for the Company's
network build-out. The terms of some of the leases include a reduction of
rental payments and scheduled rent increases at specified intervals during the
term of the leases. The Company is recognizing rent expense on a straight-line
basis over the life of the lease, which establishes deferred rent on the
balance sheet. As of September 30, 1999, the aggregate minimum rental
commitments under non-cancelable operating leases are as follows:

1997 and 1998, and nine months ended September 30, 1999, respectively.

   The Company has entered into a series of agreements for software licenses,
consulting, transition support and maintenance with various vendors. The total
future commitments under the agreements are approximately $6,000,000 as of
September 30, 1999.

   The Company has entered into letters of credit to facilitate local business
activities. The Company is liable under the letters of credit for
nonperformance of certain criteria under the individual contracts. The total
amount of outstanding letters of credit was $1,425,000 and $1,476,000 at

of credit reduce the amount available to be drawn under the Senior Credit
Facility (see Note 5). The Company is unaware of any events that would have
resulted in nonperformance of a contract during the year ended December 31,
1998 or the nine months ended September 30, 1999.

14. Related Parties

   The Company utilizes the services of a law firm in which the Executive Vice
President and Chief Financial Officer of the Company was also a partner. The
Company incurred expenses of approximately $110,000, $250,000, $2,123,000 and
$1,868,300 for the period ended December 31, 1996, for the years ended December
31, 1997 and 1998 and for the nine months ended September 30, 1999,
respectively, for legal services. As of December 31, 1997, 1998 and September
30, 1999, the Company owed the law firm $70,464, $160,000 and $306,087,
respectively. Subsequent to December 31, 1997, the officer resigned from the

site for program management and $1,100,000 for microwave relocation services
for all of the Company's existing regions. Fees for engineering services are
based upon Entel's customary hourly rates. For the period ended December 31,
1996 and for the years ended December 31, 1997 and 1998 and for the nine months
ended September 30, 1999, the Company paid $30,829, $1,939,795, $30,719,865 and
$63,310,066, respectively, to Entel for these services. As of December 31, 1997
and 1998 and September 30, 1999, the Company owed Entel $170,596, $21,177,516
and $10,981,097, respectively. Subsequent to December 31, 1997, the Chief
Executive Officer and Executive Vice President sold 100% of their interests in
Entel.

   In April 1997, Holding entered into an agreement to transfer PCS licenses,
operating assets, liabilities and U.S. Government financing, for the Houston,
Tampa, Melbourne and Orlando BTAs to four newly-formed entities created by
Holding's existing stockholder group: THC of Houston, Inc.; THC of Tampa, Inc.;
THC of Melbourne, Inc.; and THC of Orlando, Inc. (the THC entities). These
assets and liabilities were transferred in exchange for investment units of the
newly-formed THC entities which consisted of Class A, B and C common stock and
Series A preferred stock in August 1997. The carrying amount of the total
assets and liabilities transferred was $15,678,814 and $12,034,212,
respectively. Simultaneously, Holding reacquired shares of its preferred and
common stock in a $6,370,070 partial stock redemption through the exchange of
the investment units in the newly-formed companies of $3,644,602, which
represented the net difference between the cost of the assets and liabilities
transferred and the issuance of an aggregate of $2,725,468 of notes payable to
those newly-formed THC entities. Summarized below is a reconciliation of this
activity:

</TABLE>

   As a result of this transfer, Holding no longer retains any ownership
interest in the THC entities. Because this transaction was nonmonetary in
nature and occurred between entities with the same stockholder group, the
transaction was recorded at historical cost. Subsequent to the transfer, the
Company reduced the notes payable by $652,895, which represented certain costs
incurred by the Company on behalf of the THC entities for the year ended
December 31, 1997 pursuant to Transfer Agreements and Management Agreements.
The combined amounts owed THC Houston, Inc., THC Tampa, Inc., THC Melbourne,
Inc., and THC Orlando, Inc. of $2,072,573 as of December 31, 1997 were repaid
in full during 1998. As of December 31, 1998 and September 30, 1999, the
combined amounts owed by the Company to THC Houston, Inc., THC Tampa, Inc., THC
Melbourne, Inc., and THC Orlando, Inc. were $547,047 and $2,491, respectively.

   As of December 31, 1997, the Company had amounts payable of $824,164 to
TeleCorp WCS, Inc. (WCS), an affiliate, formerly TeleCorp Management
Corporation, Inc. The amount payable to WCS represented $1,200,000 of funds
received by the Company on behalf of WCS related to wireless communications
service licenses owned by WCS reduced by expenses and other payments owed by
WCS to the Company. The entire balance due WCS as of December 31, 1997 was
repaid during 1998.

   Pursuant to a Management Agreement, TeleCorp Management Corp. (TMC) provides
assistance to the Company in the form of administrative, operational,
marketing, regulatory and general business services. For these services,
beginning in July 1998, the Company pays a management fee to TMC of $550,000
per year plus reimbursement of certain business expenses, payable in equal
monthly installments, plus an annual bonus. The

upon the occurrence of certain defined events. TMC may terminate the agreement
at any time with proper notice. The Officers of TMC own all of the ownership
interest in TMC. For the year ended December 31, 1998, the Company paid
approximately $250,000 to TMC for these services plus $282,500 in bonuses to
TMC officers. For the nine months ended September 30, 1999, the Company paid
approximately $1,073,000 to TMC for these services.

   The Company has entered into a Master Site Lease Agreement with American
Towers, Inc., a company partially owned by certain stockholders of the Company.
Under this arrangement American Towers provides network site leases for PCS
deployment. The Company has incurred $16,862 and $77,460 expense for the year
ended December 31, 1998 and the nine months ended September 30, 1999,
respectively.

15. Defined Contribution Plan

   During 1998, the Company established the TeleCorp Communications, Inc.
401(k) Plan (the 401(k) Plan), a defined contribution plan in which all
employees over the age of 21 are immediately eligible to participate in the
401(k) Plan. TeleCorp Communications, Inc. is a wholly-owned subsidiary of the
Company. Under the 401(k) Plan, participants may elect to withhold up to 15% of
their annual compensation, limited to $160,000 of total compensation as
adjusted for inflation. The Company may make a matching contribution based on a
percentage of the participant's contributions. Participants vest in the
Company's matching contributions as follows: 20% after one year; 60% after two
years and 100% after three years. Total Company contributions to the 401(k)
Plan were $505,495 and $628,262 for the year ended December 31, 1998 and for
the nine months ended September 30, 1999, respectively.

16. Subsidiary Guarantee

   On April 23, 1999, the Company completed the issuance and sale of 11 5/8%
Senior Subordinated Discount Notes. The Notes are fully and unconditionally
guaranteed on a joint and several basis by TeleCorp Communications, Inc., one
of the Company's wholly-owned subsidiaries. Summarized financial information of
TeleCorp, TeleCorp Communications, Inc. and non-guarantor subsidiaries as of

17. Subsequent Events

 Initial Public Offering

   On November 22, 1999, the Company filed a new registration statement with
the Securities and Exchange Commission increasing its initial public offering
to 9,200,000 shares of Class A common stock which it priced at $20 per share.

 Concurrent Offering

   On November 22, 1999, the Company filed a new registration statement with
the Securities and Exchange Commission to increase its concurrent offering to
AT&T Wireless to 1,950,000 shares of class A common stock which it priced at
$18.65 per share.

 Deferred Compensation

   Upon an initial public offering, the variable stock option awards (see Note
10) will reach their measurement date. At that point, the Company will record
deferred compensation expense based on the difference between the estimated
fair value and the exercise price of the award. Deferred compensation has been
estimated to be $11,100,000 and will be recognized as compensation expense over
the related vesting periods, of which approximately $2,000,000 will be recorded
as compensation expense in the fourth quarter of 1999.

   In addition, certain variable restricted stock awards will become fixed upon
effectiveness of an initial public offering (see Note 9). This will result in
estimated deferred compensation of approximately $62,800,000 of which
$21,200,000 will be recorded as compensation expense in the fourth quarter of
1999.

   Certain employees, the Chief Executive Officer and the Executive Vice
President of the Company will be issued a total of 1,111 shares and 503,022
shares of mandatorily redeemable Series E preferred stock and Class A common
stock, respectively, pending final FCC approval of the share issuance related
to the Viper Wireless transaction. The Chief Executive Officer's and the
Executive Vice President's shares vest immediately and the employees' shares
vest ratably over five years. The total estimated fair value of these shares,
based on the initial public offering price, is approximately $10,100,000, which
the Company expects to record as deferred compensation, of which $6,500,000 is
expected to be recorded as compensation expense in the fourth quarter of 1999
if final share transfer approval is received from the FCC.

 Stock Split

   On November 8, 1999, the Company filed an amendment to its certificate of
incorporation with the Delaware Secretary of State to effect a 3.09-for-1 stock
split of its outstanding and authorized Series F preferred stock and all
classes of its common stock. The stock split has been retroactively reflected
in the financial statements for all periods presented. In addition, the
amendment to the Company's certificate of incorporation increased the
authorized number of shares of each of the Class A common stock and the Class B
common stock by 15 million. In addition, the Board of Directors and the
stockholders approved further amendments and restatements to the Company's
certificate of incorporation to become effective upon the closing of the
Company's pending initial public offering, including a 300 million increase in
the number of authorized shares of the Company's class A common stock.

                                 ------------

 Pending Acquisitions

   On October 18, 1999, the Company agreed to acquire TeleCorp LMDS, Inc.
(TeleCorp LMDS) through a purchase of all of the outstanding stock of TeleCorp
LMDS for an estimated aggregate purchase price of approximately $19,200,000.
The consideration will be comprised of Series C preferred stock and Class A
common stock. TeleCorp LMDS' only assets are LMDS licenses. The purchase price
has been preliminarily allocated to the acquired licenses, subject to
adjustment, based on a final valuation. TeleCorp LMDS' stockholders are Mr.
Vento, Mr. Sullivan and three of our Cash Equity Investors. By acquiring
TeleCorp LMDS, the Company will gain local multipoint distribution service, or
LMDS. The LMDS licenses will provide the Company with additional airwaves to
use as back-haul portions of the Company's PCS network traffic in several of
the Company's markets.

   On October 14, 1999, the Company agreed to purchase 15 MHz of additional
airwaves in the Lake Charles, Louisiana basic trading area from Gulfstream
Telecomm, L.L.C. Total consideration approximates $2,700,000 and consists of
approximately $400,000 in cash plus the assumption of approximately $2,300,000
in debt related to the license. Additionally, the Company will reimburse Gulf
Telecomm for all interest it paid to the FCC on debt related to the license
from June 1998 until the date the transaction is completed.

   Each of these agreements are subject to governmental approvals and other
customary conditions to closing, but no assurance can be given that they will
be closed on schedule or at all.

 Vendor Financing

   In October 1999, the Company entered into an amended and restated note
purchase agreement with Lucent for the issuance of up to $12,500,000 of new
series A notes and up to $12,500,000 of new series B notes under a vendor
expansion facility in connection with prior acquisitions of licenses in certain
markets. The terms of these notes issued under these facilities are identical
to the original Lucent series A and series B notes.

   In addition, pursuant to the amended and restated note purchase agreement,
Lucent has agreed to make available up to an additional $50.0 million of new
vendor financing not to exceed an amount equal to 30% of the value of
equipment, software and services provided by Lucent in connection with any
additional markets we acquire. This $50.0 million of availability is subject to
a reduction up to $20 million on a dollar for dollar basis of any additional
amounts Lucent otherwise lends to us for such purposes under our senior credit
facilities. Any notes purchased under this facility would be divided equally
between Lucent series A and series B notes.

   The terms of Lucent series A and series B notes issued under these expansion
facilities would be identical to the terms of the original Lucent series A and
series B notes as amended, including a maturity date of October 23, 2009.

   In addition, any Lucent series B notes issued under the vendor expansion
facility will mature and will be subject to mandatory prepayment on a dollar
for dollar basis out of the net proceeds of any future public or private
offering or sale of debt securities, exclusive of any private placement of
notes issued to finance any additional markets and borrowings under the senior
credit facilities or any replacement facility.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED

                       CONSOLIDATED FINANCIAL STATEMENTS

                                 ------------

   On October 18, 1999, the Company agreed to acquire TeleCorp LMDS, Inc.
through a purchase of all of the outstanding stock of TeleCorp LMDS for an
aggregate purchase price of approximately $19,200,000. The consideration will
be comprised of Series C preferred stock and Class A Common Stock. TeleCorp
LMDS' only assets are LMDS licenses. The purchase price has been preliminarily
allocated to the acquired licenses, subject to adjustment based upon a final
valuation. TeleCorp LMDS' stockholders are Mr. Vento, Mr. Sullivan and three of
the Company's Cash Equity Investors. By acquiring TeleCorp LMDS, the Company
will gain local multipoint distribution service, or LMDS. The LMDS licenses
will provide the Company with additional airwaves the Company can use to back-
haul portions of its PCS network traffic in several of its markets.

   On October 14, 1999, the Company agreed to purchase 15 MHz of additional
airwaves from Gulf Telecomm, LLC for $362,844 in cash, the assumption of
approximately $2.3 million of FCC debt and the reimbursement of Gulf Telecomm
for all interest paid to the FCC from June 1998 until the transaction is
completed. This acquisition has not been included in the unaudited pro forma
condensed consolidated financial statements due to its immateriality.

   The proforma adjustments result from the following:

  (i)  The amortization of the extension of the Network Membership License
       Agreement related to the AT&T Puerto Rico acquisition as if the
       transaction occurred on January 1, 1998, and
  (ii)  The accretion of manditorily redeemable preferred stock issued
        related to asset acquisitions which have completed (AT&T Puerto Rico,
        Wireless 2000, Digital PCS and Viper Wireless) or to be issued
        related to pending acquisitions (TeleCorp LMDS) as if the
        transactions occurred on January 1, 1998.
  (iii)  Certain employees, the Chief Executive Officer and the Executive
         Vice President of the Company will be issued a total of 1,111 shares
         and 503,022 shares of mandatorily redeemable Series E preferred
         stock and Class A common stock, respectively, pending final FCC
         approval of the share issuance related to the Viper Wireless
         transaction. The Chief Executive Officer and the Executive Vice
         President's shares vest immediately and the employees' shares vest
         ratably over five years. The total estimated fair value of these
         shares, based on the initial IPO price, is approximately $10,100,000
         which the Company expects to record as deferred compensation of
         which $6,500,000 is expected to be recorded as compensation expense
         in the fourth quarter of 1999 if final share transfer approval is
         received from the FCC.
