                               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 20 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 16% of our class A common stock upon
completion of this offering. 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 38% 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 12% of our class A
     common stock on a fully-diluted basis upon completion of this 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, we will have
     approximately $1.5 billion of funded and committed capital. We believe
     our existing capital resources, including the proceeds of this 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.

(1) Our restated certificate of incorporation provides that, subject to the
    rights of specific classes of stock to vote as a class on specified
    matters, until ownership restrictions of the Federal Communications
    Commission currently applicable to us no longer apply, the holders of our
    class A common stock will collectively possess 49.9% of the total voting
    power of the outstanding common stock. Our founders, Mr. Vento and Mr.
    Sullivan, as the holders of our voting preference common stock,
    collectively possess 50.1% of the total voting power of our outstanding
    common stock. See, "Business--Governmental Regulation--FCC Designated
    Entity and Small Business Regulation," "Principal Stockholders and
    Beneficial Ownership of Management" and "Description of Capital Stock."

(2) Includes the following number of shares of class A common stock that are
    issuable upon conversion of certain of our other securities that will be
    outstanding after this offering:

    .  14,912,778 shares issuable to the holders of our series F preferred
       stock at their option at any time,

    .  1,138,332 shares issuable to the holders of our class C, class D and
       voting preference common stock upon the consent of two-thirds of the
       class A common stock after the FCC ownership restrictions no longer
       apply to us, and

    .  552,505 shares issuable upon the exercise of outstanding employee and
       director options as of September 30, 1999 at a weighted average
       exercise price of $0.0065 per share, including 212,005 shares
       issuable within one year of completion of this offering. In addition,
       1,261,816 shares of class A common stock are available for awards
       under our 1999 Stock Option Plan and 118,390 shares are available for
       grant under our 1998 Restricted Stock Plan.

  Excluded from equivalents presented above are shares of class A common
  stock issuable to holders of our series A preferred stock at their option
  at any time after July 17, 2006, at a conversion rate equal to the
  liquidation preference on those shares divided by the market price of the
  class A common stock at the time of conversion. At the September 30, 1999
  liquidation preference of the series A preferred shares of approximately
  $107.0 million and a market price equal to an assumed initial public
  offering price of this offering of $17.00 per share, the outstanding shares
  of series A preferred stock would convert into 6,291,928 shares of class A
  common stock. See "Description of Capital Stock." Also excluded are
  1,337,322 shares to be issued in connection with pending acquisitions. See
  "Management's Discussion and Analysis of Financial Condition and Results of
  Operations--Acquisition History" and "--Recent Developments."

     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.

(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, Inc., 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.

                                  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 operating 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 offering, the value of some outstanding stock option and
restricted stock awards will become fixed and a portion of them will be fully
vested. Based on an assumed initial public offering price of $17.00 per share,
we expect to record approximately $24.8 million of additional compensation
expense in the fourth quarter of 1999 in connection with these awards. We
expect to recognize an additional $46.5 million will be recognized 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
<PAGE>

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."

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
radio airwaves to each user to permit many simultaneous conversations on one
radio airwave channel. Other digital

                                       12
<PAGE>

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 36.4% of our total voting power, in the aggregate, after this
offering. 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, we will have 81,673,889 shares of class A common stock
outstanding, or 82,843,889 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 the September 30, 1999
liquidation preference of the series A preferred stock and an assumed initial
public offering price of $17.00 per share, 6,291,928 shares of class A common
stock are 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 remaining
shares of our outstanding class A common stock, representing approximately
90.4% 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

   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;

                                       15
<PAGE>

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

  .  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.

   We expect the initial public offering price will be substantially higher
than the net tangible book value of each outstanding share of common stock.
Purchasers of 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 in net tangible book deficit will be $21.60 per share of
the class A common stock at an assumed initial public offering price of $17.00
per share, which is the midpoint of the initial public offering price range set
forth on the cover of this prospectus.

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.

                                USE OF PROCEEDS

   We estimate that the net proceeds from the sale of the 7,800,000 shares of
class A common stock in this offering will be approximately $122.3 million at
an assumed initial public offering price of $17.00 per share and after
deducting the estimated underwriting discounts and estimated offering expenses.
If the underwriters exercise their over-allotment option in full, we estimate
that our net proceeds will be approximately $140.9 million.

   We expect to use the net proceeds of this 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, 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 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 and the sale of 7,800,000 shares of class A common stock in this
     offering at an assumed initial public offering price of $17.00 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

                                    DILUTION

   If you invest in our class A common shares, 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. 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 7,800,000 class A common shares we are offering under this
prospectus, at an assumed initial public offering price per class A common
share of $17.00, and after deducting underwriting discounts and our estimated
expenses in connection with this offering, our net tangible book deficit as of
September 30, 1999, would have been approximately $(375,309,310) or
approximately $(4.60) per class A common share. This represents an immediate
decrease in net tangible book deficit of $2.14 per class A common share to
existing shareholders and an immediate dilution of $(21.60) per class A common
share to new investors. 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

deducting the underwriting discounts and estimated offering expenses payable by
us, at an assumed public offering price of $17.00 per share.

</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 an assumed initial public
offering price of $17.00 per share, 6,291,928 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 offering would be $(2.57). This represents an immediate
dilution in net tangible book deficit of $19.57 per share to purchasers of
class A common shares in the 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 the offering, the value of some outstanding stock option and
restricted stock awards will become fixed, although most of the awards will
remain subject to vesting requirements over approximately four years.
Accordingly, we will record approximately $71.3 million on our balance sheet as
deferred compensation and additional paid-in capital, based on an assumed
initial public offering price of $17.00 per share. This amount will be
amortized in the statement of operations as additional compensation expense as
the vesting requirements are met. Because some of these awards will be vested
upon the closing of this offering, we will record a charge of approximately
$24.8 million of the $71.3 million on our statement of operations as
compensation expense for the fourth quarter of 1999.

   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 $95.0 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 recently 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 $87.4 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 $105.7
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 $10 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 8.29%. 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
<PAGE>


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 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 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 for the first
nine months of 1999. We estimate capital expenditures for year 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 $1.2 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 $11.3 million, less a discount of $1.4
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 $140.0 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 $4.0 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, 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:

    mobile radio and PCS and enhanced specialized mobile radio technology
    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 20 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 and Martha's Vineyard, 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 38% 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 12% of our class
     A common stock on a fully-diluted basis upon completion of this
     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 we will have
     approximately $1.5 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 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
       .  Cape Cod             .  Little Rock           .  Nantucket
                                                        .  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 five of these ten markets, Jackson, Tennessee, Hammond,
Louisiana, Jonesboro, Arkansas, 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
<PAGE>

 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

 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.

  .  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

     initial investors other than AT&T on the one hand, and AT&T Wireless on
     the other hand;

items above will expire.

of stockholders. Ms. Hawkins-Key and Messrs. Hannon and Desai will be in the

meeting and $500 for participating in each teleconference. The directors are

compensation that we paid in the 1998 fiscal year to Mr. Vento, our Chief

upon achievement of corporate and individual performance objectives; however
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

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, 6,687 shares of series E preferred
stock and 3,799,832 shares of class A common stock are outstanding under this
plan. We repurchased an additional 1,155 shares of series E preferred stock and
813,712 shares of class A common stock from our stockholders, which we had
granted under this plan, and we have regranted some 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 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,
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.

(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 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

                 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 35.71% 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.

our board be approved by the affirmative vote of a majority of our entire

     the other hand;

   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.

                                       76

   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;

                                       77
<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.

                                       78

   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 voting common stock or class E
preferred stock from one of our employees in connection with the termination of
the employee's employment with us.

                                       79
<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 voting common stock;

  .  class B non-voting 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 voting 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
voting 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.

 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;

                                       81
<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-

                                      82
<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

                                       83
<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 $95.0 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 5,244 and 2,334,186 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 variable awards vest based upon certain events taking place, including our
reaching milestones in our minimum construction plan.

   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."

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.


                                       85

   AT&T owns stock in us and in Tritel Communications, and we may be deemed
affiliates by virtue of common ownership. Mr. Anderson and Mr. Fuqua, two of
our directors, also serve as directors of Tritel Communications. See
"Management." AT&T, CB Capital Investors and Equity-Linked Investors own stock
in us and in Triton PCS, and we may be deemed affiliates by virtue of common
ownership. Ms. Hawkins-Key, our director nominated by AT&T Wireless, and Mr.
Anderson also serve as directors of Triton PCS. See "Management."

   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.

                                      86
<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 $57,772, and of the class A common stock is $3,907. 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.


                                       89
<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;

  (3) 100% of the net cash proceeds of issuances of debt obligations, other
      than debt obligations permitted by the senior credit agreement,
      including the issuance of the notes; and

  (4) 50% of the net cash proceeds of issuances of equity securities, other
      than in connection with our equity investments and other than the
      proceeds of this offering, and, provided that, this clause (4) shall
      not apply at any time we have a class of equity securities publicly
      held;

provided that the prepayments and reductions described under clauses (3) and
(4) will not be required if, after giving effect to the issuance:

  (A) our leverage ratio would be less than 5.0 to 1.0; and

  (B) in the case of clause (4), we would be in pro forma compliance with
      each covenant contained in the senior credit agreement.

   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 $10 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

                                       90
<PAGE>

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:

      2006...........................................................  101.938%
      2007 and thereafter............................................  100.000%
</TABLE>

   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;


                                      91
<PAGE>

  .  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 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.

   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

                                       93
<PAGE>

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.

   Our authorized capital stock, as set forth in our restated certificate of
incorporation that will become effective upon closing of this offering, will

    .  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 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

   The holders of series A preferred stock and series B preferred stock are

related to their shares; provided that so long as any shares of series A
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.

Listing

   We have applied for quotation of our class A common stock on the Nasdaq
National Market under the trading symbol "TLCP."

                        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, we will have outstanding an aggregate of
81,673,889 shares of class A common stock assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options. Of
these shares, all of the shares sold in this offering, other than shares held
by our "affiliates" and certain of our other key employees other than 390,000
shares sold pursuant to the directed share program, 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 73,873,889 shares of
class A common stock that are not being sold in this offering, but which will
be outstanding at the time this offering is complete, will be eligible for sale
into the public market:

                                         stockholders have with the
                                         underwriters, subject to vesting
                                         requirements listed in our 1998
                                         Restricted Stock Plan. However, the
                                         underwriters can waive this
                                         restriction and allow these
                                         stockholders to sell their shares at
                                         any time.

                                         parties thereto, in which case all
                                         such shares will be subject to resale
                                         subject to volume limitations and, in

                                         Stockholders' agreement.
</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 90 days after
the date of this prospectus, 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 approximately816,739 class A common shares immediately after this
     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
90 days after the effective date of this offering 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:

   .  beginning 90 days after the date of this prospectus;

   .  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 86,037,088 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. 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.

   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.

   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, 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 $    per share. The
underwriters may allow, and these dealers may reallow, a concession not in
excess of $    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 1,170,000 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.

   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 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.

   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

                                      108

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.

                                 LEGAL MATTERS

   Certain legal matters in connection with the common stock we are offering
under this prospectus are being passed upon for us by McDermott, Will & Emery.
The underwriters have been represented by Cravath, Swaine & Moore. Wiley, Rein
& Fielding are also advising us on regulatory matters under the Federal
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
rendered.

   Equipment revenue is recognized upon delivery of the equipment to the
customer and when future obligations are no longer significant.

 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:

</TABLE>

   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:

<TABLE>
   <S>                              <C>

   Leasehold improvements.......... Lesser of useful life or lease term
</TABLE>

   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.

 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.

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.

   In addition, Lucent has agreed to make available up to an additional
$80,000,000 of junior subordinated vendor financing in amounts up to 30% of the
value of the equipment, software and services provided by Lucent in connection
with any additional markets the Company acquires, subject to certain conditions
as specified (the Vendor Expansion Facility). The expiration date for any notes
issued pursuant to the Vendor Expansion Facility is the date which is six
months after the scheduled maturity of the Notes, subject to mandatory
prepayment if certain future events occur.

 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.

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.

     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

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-

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.

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
period ended September 30, 1999 represent variable awards

   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,

   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

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:

   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

Senior Subordinated Discount Notes. The Notes are fully and unconditionally
guaranteed on a joint and several basis by TeleCorp Communications, Inc., one

17. Subsequent Events

 Initial Public Offering

   On November 2, 1999, the Company filed a preliminary prospectus with the
Securities and Exchange Commission for an initial public offering of 7,800,000
shares of Class A common stock with an estimated price range of $16 to $18 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 $9,400,000 and will be recognized as compensation expense over
the related vesting periods, of which approximately $1,700,000 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 $53,300,000 of which
$17,600,000 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 is
approximately $8,600,000, which will be recorded as deferred compensation, of
which $5,500,000 will 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 $16,900,000.
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 $16,900,000. 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 is approximately $8,600,000 which will be recorded as
         deferred compensation of which $5,500,000 will be recorded as
         compensation expense in the fourth quarter of 1999 if final share
         transfer approval is received from the FCC.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   As permitted by Section 101(b)(7) of the DGCL, 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: (1) for any breach
of the director's or executive officer's duty of loyalty to us or our
stockholders; (2) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (3) for unlawful
dividends and stock purchases under the DGCL; or (4) for any transaction from
which the director derived an improper personal benefit.

   In addition, Section 145 of the General Corporation Law of the State of
Delaware ("DGCL") provides that a corporation may indemnify a director,
officer, employee or agent against expenses (including attorneys' fees),
judgements, fines and for amounts paid in settlement in respect of or in
successful defense of any action, suit or proceeding if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interest of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.

   Our bylaws provide that: (1) we must indemnify our directors and officers to
the fullest extent permitted by Delaware law, subject to very limited
exceptions; (2) 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 (3) 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.

   Prior to the closing of this offering, we intend to enter 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.

ITEM 17. UNDERTAKINGS.

   (a) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant under the foregoing provisions, or otherwise, the registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling persons of the
registrant in the successful defense of any action suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether the indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.

   (b) The undersigned registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

          1.  Representations and Warranties.  The Company represents and
              -------------------------------
warrants to, and agrees with, each Underwriter as set forth below in this
Section 1.

          (a)  The Company has prepared and filed with the Commission a
     registration statement (file number 333-89393) on Form S-1, including a
     related preliminary prospectus, for registration under the Act of the
     offering and sale of the Securities.  The Company may have filed one or
     more amendments thereto, including a related preliminary prospectus, each
     of which has previously been furnished to you.  The Company will next file
     with the Commission either (1) prior to the Effective Date of such
     registration statement, a further amendment to such registration statement
     (including the form of final prospectus) or (2) after the Effective Date of
     such registration statement, a final prospectus in accordance with Rules
     430A and 424(b). In the case of clause (2), the Company has included in
     such registration statement, as amended at the Effective Date, all
     information (other than Rule 430A Information) required by the Act and the
     rules thereunder to be included in such registration statement and the
     Prospectus.  As filed, such amendment and form of final prospectus, or such
     final prospectus, shall contain all Rule 430A Information, together with
     all other such required information, and, except to the extent the
     Representatives shall agree in writing to a modification, shall be in all
     substantive respects in the form furnished to you prior to the Execution
     Time or, to the extent not completed at the Execution Time, shall contain
     only such specific additional information and other changes (beyond that
     contained in the latest Preliminary Prospectus) as the Company has advised
     you, prior to the Execution Time, will be included or made therein.

          (b)  On the Effective Date, the Registration Statement did or will,
     and when the Prospectus is first filed (if required) in accordance with
     Rule 424(b) and on the Closing Date (as defined herein) and on any date on
     which Option Securities are purchased, if such date is not the Closing Date
     (a "settlement date"), the Prospectus (and any supplements thereto) will,
     comply in all material respects with the applicable requirements of the Act
     and the rules thereunder; on the Effective Date and at the Execution Time,
     the Registration Statement did not or will not contain any untrue statement
     of a material fact or omit to state any material fact required to be stated
     therein or necessary in order to make the statements therein not
     misleading; and, on the Effective Date, the Prospectus, if not filed
     pursuant to Rule 424(b), will not, and on the date of any filing pursuant
     to Rule 424(b) and on the Closing Date and any settlement date, the
     Prospectus (together with any supplement thereto) will not, include any
     untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
                                                               --------

     -------
     information contained in or omitted from the Registration Statement, or the
     Prospectus (or any supplement thereto) in reliance upon and in

     partnerships in good standing under the laws of their respective
     jurisdictions of incorporation or formation, are duly qualified to do
     business and are in good standing as foreign corporations, limited
     liability companies or limited partnerships in each jurisdiction in which

     respective businesses requires such qualification, and have all power and
     authority necessary to own or hold their respective properties and to
     conduct the businesses in which they are engaged, except where the failure
     to so qualify or have such power or authority would not, singularly or in
     the aggregate, have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business.

          (d)  As of the Closing Date, the Company will have an authorized
     equity  capitalization as set forth in the Prospectus under the heading

     Market, Inc. for listing, subject to official notice of issuance and
     evidence of satisfactory distribution; the certificates for the Securities
     are in valid and sufficient form; the holders of outstanding shares of
     capital stock of the Company are not entitled to preemptive or other rights
     to subscribe for the Securities; and, except as set forth in the

     other obligations to issue, or rights to convert any obligations into or
     exchange any securities for, shares of capital stock of or ownership
     interests in the Company are outstanding.

          (e)  All of the outstanding shares of capital stock of each subsidiary

     transfer or any other claim of any third party, other than (i) liens,

     Regulation" fairly summarize the matters therein described.

          (g)  This Agreement has been duly authorized, executed and delivered
     by the Company and constitutes a valid and binding obligation of the
     Company enforceable in accordance with its terms.

          (h) The Company is not and, after giving effect to the offering and
     sale of the Securities and the application of the proceeds thereof as
     described in the Prospectus, will not be an "investment company" as defined
     in the Investment Company Act of 1940, as amended.  Neither the Company nor
     any of its subsidiaries is a "holding company" or a "subsidiary company" of
     a holding company or an "affiliate" thereof within the meaning of the
     Public Utility Holding Company Act of 1935, as amended.

          (i)  No consent, approval, authorization, filing with or order of any
     court or governmental agency or body is required in connection with the
     transactions contemplated herein, except such as have been obtained under
     the Act and such as
<PAGE>

                                                                               5

     may be required under the blue sky laws of any jurisdiction in connection
     with the purchase and distribution of the Securities by the Underwriters in
     the manner contemplated herein and in the Prospectus.

          (j)  Neither the issue and sale of the Securities nor the consummation
     of any other of the transactions herein contemplated nor the fulfillment of
     the terms hereof will conflict with, result in a breach or violation or
     imposition of any lien, charge or encumbrance upon any property or assets
     of the Company or any of its subsidiaries pursuant to, (i) the charter or
     by-laws of the Company or any of its subsidiaries, (ii) the terms of any
     indenture, contract, lease, mortgage, deed of trust, note agreement, loan
     agreement or other agreement, obligation, condition, covenant or instrument
     to which the Company or any of its subsidiaries is a party or bound or to
     which its or their property is subject, or (iii) any statute, law, rule,
     regulation, judgment, order or decree applicable to the Company or any of
     its subsidiaries of any court, regulatory body, administrative agency,
     governmental body, arbitrator or other authority having jurisdiction over
     the Company or any of its subsidiaries or any of its or their properties.

          (k)  No holders of securities of the Company have rights to the
     registration of such securities under the Registration Statement that have
     not been waived.

          (l)  The audited and unaudited consolidated historical financial
     statements and schedules of the Company and its consolidated subsidiaries
     included in the Prospectus and the Registration Statement present fairly in
     all material respects the financial condition, results of operations and
     cash flows of the Company as of the dates and for the periods indicated,
     comply as to form with the applicable accounting requirements of the Act
     and have been prepared in conformity with generally accepted accounting
     principles applied on a consistent basis throughout the periods involved
     (except as otherwise noted therein).  The selected financial data set forth
     under the caption "Selected Historical and Pro Forma Consolidated Financial
     Information" in the Prospectus and Registration Statement fairly present,
     on the basis stated in the Prospectus and the Registration Statement, the
     information included therein.  The historical financial information
     contained in the Prospectus under the headings "Capitalization", "Selected
     Historical and Pro Forma Consolidated Financial Information" and
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations" is derived from the accounting records of the entities covered
     thereby and fairly present the information purported to be shown thereby.
     The pro forma financial statements included in the Prospectus and the
     Registration Statement include assumptions that provide a reasonable basis
     for presenting the significant effects directly attributable to the
     transactions and events described therein, the related pro forma
     adjustments give appropriate effect to those assumptions, and the pro forma
     adjustments reflect the proper application of those adjustments to the
     historical financial statement
<PAGE>

                                                                               6

     amounts in the pro forma financial statements included in the Prospectus
     and the Registration Statement. The pro forma financial statements included
     in the Prospectus and the Registration Statement comply as to form in all
     material respects with the applicable accounting requirements of Regulation
     S-X under the Act and the pro forma adjustments have been properly applied
     to the historical amounts in the compilation of those statements.

          (m)  No action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company or any of its subsidiaries or its or their property is pending or,
     to the best knowledge of the Company, threatened that (i) could reasonably
     be expected to have a material adverse effect on the performance of this
     Agreement or the consummation of any of the transactions contemplated
     hereby or (ii) could reasonably be expected to have a material adverse
     effect on the condition (financial or otherwise), prospects, earnings,
     business or properties of the Company and its subsidiaries, taken as a
     whole, whether or not arising from transactions in the ordinary course of
     business, except as set forth in or contemplated in the Prospectus
     (exclusive of any supplement thereto).

          (n)  Each of the Company and each of its subsidiaries owns or leases
     all such properties as are necessary to the conduct of its operations as
     presently conducted.

          (o)  Neither the Company nor any subsidiary is in violation or default
     of (i) any provision of its charter or bylaws, (ii) the terms of any
     indenture, contract, lease, mortgage, deed of trust, note agreement, loan
     agreement or other agreement, obligation, condition, covenant or instrument
     to which it is a party or bound or to which its property is subject, or
     (iii) any statute, law, rule, regulation, judgment, order or decree of any
     court, regulatory body, administrative agency, governmental body,
     arbitrator or other authority having jurisdiction over the Company or such
     subsidiary or any of its properties, as applicable.

          (p)  PricewaterhouseCoopers LLP, who have certified certain financial
     statements of the Company and its consolidated subsidiaries and delivered
     their report with respect to the audited consolidated financial statements
     and schedules included in the Prospectus, are independent public
     accountants with respect to the Company within the meaning of the Act and
     the applicable published rules and regulations thereunder.

          (q)  The Company has filed all foreign, federal, state and local tax
     returns that are required to be filed or has requested extensions thereof
     (except in any case in which the failure so to file would not have a
     material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of
<PAGE>

                                                                               7

     the Company and its subsidiaries, taken as a whole, whether or not arising
     from transactions in the ordinary course of business, except as set forth
     in or contemplated in the Prospectus (exclusive of any supplement thereto))
     and has paid all taxes required to be paid by it and any other assessment,
     fine or penalty levied against it, to the extent that any of the foregoing
     is due and payable, except for any such assessment, fine or penalty that is
     currently being contested in good faith or as would not have a material
     adverse effect on the condition (financial or otherwise), prospects,
     earnings, business or properties of the Company and its subsidiaries, taken
     as a whole, whether or not arising from transactions in the ordinary course
     of business, except as set forth in or contemplated in the Prospectus
     (exclusive of any supplement thereto).

          (r)  No labor problem or dispute with the employees of the Company or
     any of its subsidiaries exists or is threatened or imminent, and the
     Company is not aware of any existing or imminent labor disturbance by the
     employees of any of its or its subsidiaries' principal suppliers,
     contractors or customers, that could have a material adverse effect on the
     condition (financial or otherwise), prospects, earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto).

          (s)  The Company and each of its subsidiaries are insured by insurers
     of recognized financial responsibility against such losses and risks and in
     such amounts as are prudent and customary in the businesses in which they
     are engaged; all policies of insurance and fidelity or surety bonds
     insuring the Company or any of its subsidiaries or their respective
     businesses, assets, employees, officers and directors are in full force and
     effect; the Company and its subsidiaries are in compliance with the terms
     of such policies and instruments in all material respects; and there are no
     claims by the Company or any of its subsidiaries under any such policy or
     instrument as to which any insurance company is denying liability or
     defending under a reservation of rights clause; neither the Company nor any
     such subsidiary has been refused any insurance coverage sought or applied
     for; and neither the Company nor any such subsidiary has any reason to
     believe that it will not be able to renew its existing insurance coverage
     as and when such coverage expires or to obtain similar coverage from
     similar insurers as may be necessary to continue its business at a cost
     that would not have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto).

                                                                               8

          (t)  The Company and its subsidiaries possess all licenses,
     certificates, permits and other authorizations issued by the appropriate
     federal, state or foreign regulatory authorities necessary to conduct their
     respective businesses, and neither the Company nor any such subsidiary has
     received any notice of proceedings relating to the revocation or
     modification of any such certificate, authorization or permit which, singly
     or in the aggregate, if the subject of an unfavorable decision, ruling or
     finding, would have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus.

          (u)  The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets
     is compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

          (v)  The Company has not taken, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization

     the sale or resale of the Securities.

          (w)  The Company and its subsidiaries are (i) in compliance with any

     Environmental Laws to conduct their respective businesses and (iii) have
     not received notice of any actual or potential liability for the
     investigation or remediation of any disposal or release of hazardous or
     toxic substances or wastes, pollutants or contaminants, except where such
     non-compliance with Environmental Laws, failure to receive required
     permits, licenses or other approvals, or liability would not, individually
     or in the aggregate, have a material adverse change in the condition
     (financial or otherwise), prospects, earnings, business or properties of
     the Company and its subsidiaries, taken as a whole, whether or not arising
     from transactions in the ordinary course of business, except as set forth
     in or contemplated in the Prospectus (exclusive of any

     Company nor any of the subsidiaries has been named as a "potentially
     responsible party" under the Comprehensive Environmental Response,
     Compensation, and Liability Act of 1980, as amended.

          (x)  In the ordinary course of its business, the Company periodically
     reviews the effect of Environmental Laws on the business, operations and
     properties of the Company and its subsidiaries, in the course of which it
     identifies and evaluates associated costs and liabilities (including,
     without limitation, any capital or operating expenditures required for
     clean-up, closure of properties or compliance with Environmental Laws, or
     any permit, license or approval, any related constraints on operating
     activities and any potential liabilities to third parties).  On the basis
     of such review, the Company has reasonably concluded that such associated
     costs and liabilities would not, singly or in the aggregate, have a
     material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of the Company and its
     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in
     the Prospectus (exclusive of any supplement thereto).

          (y)  Each of the Company and its subsidiaries has fulfilled its
     obligations,  if any, under the minimum funding standards of Section 302 of
     the United States Employee Retirement Income Security Act of 1974 ("ERISA")
     and the regulations and published interpretations thereunder with respect
     to each "plan" (as defined in Section 3(3) of ERISA and such regulations
     and published interpretations) in which employees of the Company and its
     subsidiaries are eligible to participate and each such plan is in
     compliance in all material respects with the presently applicable
     provisions of ERISA and such regulations and published interpretations.
     The Company and its subsidiaries have not incurred any unpaid liability to
     the Pension Benefit Guaranty Corporation (other than for the payment of
     premiums in the ordinary course) or to any such plan under Title IV of
     ERISA.

          (z)  The Company and its subsidiaries own, possess, license or have
     other rights to use, on reasonable terms, all trade and service marks,
     trade and service mark registrations, trade names, copyrights, licenses,
     inventions, trade secrets, technology, know-how and other intellectual
     property (collectively, the "Intellectual Property") necessary for the
     conduct of the Company's business as now conducted or as proposed in the
     Prospectus to be conducted.  Except as set forth in the Prospectus under
     the caption "Business--Intellectual Property," (a) there are no rights of
     third parties to any such Intellectual Property; (b) there is no material
     infringement by third parties of any such Intellectual Property; (c) there
     is no pending or threatened action, suit, proceeding or claim by others
     challenging the Company's rights in or to any such Intellectual Property,
     and the Company is
<PAGE>

                                                                              10

     unaware of any facts which would form a reasonable basis for any such
     claim; (d) there is no pending or threatened action, suit, proceeding or
     claim by others challenging the validity or scope of any such Intellectual
     Property, and the Company is unaware of any facts which would form a
     reasonable basis for any such claim; (e) there is no pending or threatened
     action, suit, proceeding or claim by others that the Company infringes or
     otherwise violates any patent, trademark, copyright, trade secret or other
     proprietary rights of others, and the Company is unaware of any other fact
     which would form a reasonable basis for any such claim and (f) there is no
     U.S. patent or published U.S. patent application which contains claims that
     dominate or may dominate any Intellectual Property described in the
     Prospectus as being owned by or licensed to the Company or that interferes
     with the issued or pending claims of any such Intellectual Property.
     Neither the Company nor any of its subsidiaries own, possess, license or
     have any other rights to use any patents, nor does the Company or any of
     its subsidiaries have any patent applications pending.

          (aa)  The Company and each of its subsidiaries have good and
     marketable title in fee simple to, or have valid rights to lease or
     otherwise use, all items of real and personal property which are material
     to the business of the Company and its subsidiaries, in each case free and
     clear of all liens, encumbrances, claims and defects and imperfections of
     title except such as (i) do not materially interfere with the use made and
     proposed to be made of such property by the Company and its subsidiaries or
     (ii) could not reasonably be expected to have a material adverse effect on
     the condition (financial or otherwise), prospects, earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business.

          (bb)  Except as described in the Prospectus, there are no outstanding
     subscriptions, rights, warrants, calls or options to acquire, or
     instruments convertible into or exchangeable for, or agreements or
     understandings with respect to the sale or issuance of, any shares of
     capital stock of or other equity or other ownership interest in the Company
     or any of its subsidiaries.

          (cc)  No forward-looking statement (within the meaning of Section 27A
     of the Securities Act and Section 21E of the Exchange Act) contained in the
     Prospectus has been made or reaffirmed without a reasonable basis or has
     been disclosed other than in good faith.

          (dd)  None of the Company or any of its subsidiaries does business
     with the government of Cuba or with any person or affiliate located in Cuba
     within the meaning of Florida Statutes Section 517.075.

                                                                              11

          (ee)  The Company and its subsidiaries have evaluated the accuracy of
     the representations made by (i) the vendors from whom components of the
     Company's internal information technology systems were purchased and (ii)
     the vendors from whom all network hardware was purchased regarding the risk
     that the products sold by such vendors may be unable to recognize and
     properly execute date-sensitive functions involving certain dates prior to
     and any dates after December 31, 1999 (the "Year 2000 Problem"); and the
     Company believes, after due inquiry, that each supplier, vendor, customer
     or financial service organization used or serviced by the Company and its
     subsidiaries has remedied or will remedy on a timely basis the Year 2000
     Problem.

          (ff)  Since the date as of which information is given in the
     Prospectus, (i) there has been no material adverse change or any
     development involving a prospective material adverse change in the
     condition, financial or otherwise, or in the earnings, business affairs,
     management or business prospects of the Company and its subsidiaries, taken
     as a whole, whether or not arising in the ordinary course of business, (ii)
     neither the Company nor any of its subsidiaries has incurred any material
     liability or obligation, direct or contingent, other than in the ordinary
     course of business, (iii) neither the Company nor any of its subsidiaries
     has entered into any material transaction other than in the ordinary course
     of business and (iv) except as otherwise disclosed in the Prospectus, there

     Company or any of its subsidiaries, or any dividend or distribution of any
     kind declared, paid or made by the Company or any of its subsidiaries on
     any class of their respective capital stock.

          (gg)  (i) The Company and its subsidiaries have the full use and
     benefit of all broadband personal communications services ("PCS") licenses
     issued by the Federal Communications Commission (the "FCC") to the Company

     Part F of Exhibit B upon consummation of the acquisition of a [list
     licenses to be acquired] from [                     ]; (ii) such Licenses
     have been duly issued by the FCC, are (in the case of Licenses listed on
     Parts A, B, C, D and E of Exhibit B) or will be (upon consummation of the
     relevant transaction in the case of Licenses listed on Part F of Exhibit B)
     held by a wholly owned subsidiary of the Company and are in full force and
     effect and (iii) the Company and its subsidiaries are in compliance in all

     material respects with all of the provisions of each such License held by
     any of them.

          (hh)  (i) The Company and each of its subsidiaries are in compliance
     in all material respects with the Communications Act of 1934, and any
     similar or successor federal statute, and the rules and regulations and

     Company has no knowledge of any investigation, notice of apparent
     liability, violation, forfeiture or other order or complaint issued by or
     before the FCC, or of any other proceedings (other than proceedings
     relating to the wireless communications industries generally) of or before
     the FCC, which could reasonably be expected to have a material adverse

     whole, whether or not arising from transactions in the ordinary course of
     business;  (iii) no event has occurred which (A) has resulted in, or after

     which could reasonably be expected to have a material adverse effect on the

     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business or (B)
     affects or could reasonably be expected in the future to affect any of the
     rights of the Company or any of its subsidiaries under any License held by
     the Company or any of its subsidiaries in any respect which could
     reasonably be expected to have a material adverse effect on the condition

          Any certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters in connection with the
offering of the Securities shall be deemed a representation and warranty by the
Company, as to matters covered thereby, to each Underwriter.

          2.  Purchase and Sale.  (a) Subject to the terms and conditions and in
              ------------------
reliance upon the representations and warranties herein set forth, the Company
agrees to sell to each Underwriter, and each Underwriter agrees, severally and
not jointly, to purchase from the Company, at a purchase price of $
per share, the amount of the Underwritten Securities set forth opposite such
Underwriter's name in Schedule I hereto.

          (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company hereby grants an
option to the several Underwriters to purchase, severally and not jointly, up to
1,170,000 Option Securities at the same purchase price per share as the
Underwriters shall pay for the Underwritten Securities.  Said option may be
exercised only to cover over-allotments in the sale of the Underwritten
Securities by the Underwriters.  Said option may be exercised in whole or in
part at any time (but not more than once) on or before the 30th day after the
date of the Prospectus upon written or telegraphic notice by the Representatives
to the Company setting forth the number of shares of the Option Securities as to
which the several Underwriters are exercising the option and the settlement
date.  The number of Option Securities to be purchased by each Underwriter shall
be the same percentage of the total number of shares of the Option Securities to
be purchased by the several Underwriters as such Underwriter is purchasing of
the Underwritten Securities, subject to such adjustments as you in your absolute
discretion shall make to eliminate any fractional shares.

          3.  Delivery and Payment.  Delivery of and payment for the
              ---------------------
Underwritten Securities and the Option Securities (if the option provided for in
Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
, 1999, or at such time on such later date not more than three Business Days
after the foregoing date as the Representatives shall designate, which date and
time may be postponed by agreement between the Representatives and the Company
or as provided in Section 9 hereof (such date and time of delivery and payment
for the Securities being herein called the "Closing Date").  Delivery of the
Securities shall be made to the Representatives for the respective accounts of
the several Underwriters against payment by the several Underwriters through the
Representatives of the purchase price thereof to or upon the order of the
Company by wire transfer payable in same-day funds to an account specified by
the Company.  Delivery of the Underwritten Securities and the Option Securities
shall be made through the facilities of The Depository Trust Company unless the
Representatives shall otherwise instruct.
<PAGE>

                                                                              14

          If the option provided for in Section 2(b) hereof is exercised after
the third Business Day prior to the Closing Date, the Company will deliver the
Option Securities (at the expense of the Company) to the Representatives, at 388
Greenwich Street, New York, New York, on the date specified by the
Representatives (which shall be within three Business Days after exercise of
said option) for the respective accounts of the several Underwriters, against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by wire transfer payable in
same-day funds to an account specified by the Company.  If settlement for the
Option Securities occurs after the Closing Date, the Company will deliver to the
Representatives on the settlement date for the Option Securities, and the
obligation of the Underwriters to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 6 hereof.

          4.  Offering by Underwriters.  It is understood that the several
              -------------------------
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.
<PAGE>

                                                                              15

          5.  Agreements.  The Company agrees with the several Underwriters
              -----------
that:

          (a)  The Company will use its best efforts to cause the Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereof, to become effective.  Prior to the termination of the offering of
     the Securities, the Company will not file any amendment of the Registration
     Statement or supplement to the Prospectus or any Rule 462(b) Registration
     Statement unless the Company has furnished you a copy for your review prior
     to filing and will not file any such proposed amendment or supplement to
     which you reasonably object.  Subject to the foregoing sentence, if the
     Registration Statement has become or becomes effective pursuant to Rule
     430A, or filing of the Prospectus is otherwise required under Rule 424(b),
     the Company will cause the Prospectus, properly completed, and any
     supplement thereto to be filed with the Commission pursuant to the
     applicable paragraph of Rule 424(b) within the time period prescribed and
     will provide evidence satisfactory to the Representatives of such timely
     filing.  The Company will promptly advise the Representatives (1) when the
     Registration Statement, if not effective at the Execution Time, shall have
     become effective, (2) when the Prospectus, and any supplement thereto,
     shall have been filed (if required) with the Commission pursuant to Rule
     424(b) or when any Rule 462(b) Registration Statement shall have been filed
     with the Commission, (3) when, prior to termination of the offering of the
     Securities, any amendment to the Registration Statement shall have been
     filed or become effective, (4) of any request by the Commission or its
     staff for any amendment of the Registration Statement, or any Rule 462(b)
     Registration Statement, or for any supplement to the Prospectus or for any
     additional information, (5) of the issuance by the Commission of any stop
     order suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (6) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the institution or threatening of any proceeding for such
     purpose.  The Company will use its best efforts to prevent the issuance of
     any such stop order or the suspension of any such qualification and, if
     issued, to obtain as soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     the Registration Statement or supplement the Prospectus to comply with the
     Act or the rules thereunder, the Company promptly will (1) notify the
     Representatives of any such event, (2) prepare and file with the
     Commission, subject to the second sentence of paragraph (a) of this Section
     5, an amendment or supplement which will correct such statement or omission
     or effect such
<PAGE>

                                                                              16

     compliance; and (3) supply any supplemented Prospectus to you in such
     quantities as you may reasonably request.

          (c)  As soon as practicable, but in any event not later than 15 months
     after the Effective Time, the Company will make generally available to its
     security holders and to the Representatives an earnings statement or
     statements of the Company and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)  The Company will furnish to the Representatives and counsel for
     the Underwriters signed copies of the Registration Statement (including
     exhibits thereto) and to each other Underwriter a copy of the Registration
     Statement (without exhibits thereto) and, so long as delivery of a
     prospectus by an Underwriter or dealer may be required by the Act, as many
     copies of each Preliminary Prospectus and the Prospectus and any supplement
     thereto as the Representatives may reasonably request.

          (e)  The Company will arrange, if necessary, for the qualification of
     the Securities for sale under the laws of such jurisdictions as the
     Representatives may reasonably designate and will maintain such
     qualifications in effect so long as required for the distribution of the
     Securities; provided that in no event shall the Company be obligated to
     qualify to do business in any jurisdiction where it is not now so qualified
     or to take any action that would subject it to service of process in suits,
     other than those arising out of the offering or sale of the Securities, in
     any jurisdiction where it is not now so subject.

          (f)  The Company will not, without the prior written consent of
     Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or
     otherwise dispose of, (or enter into any transaction which is designed to,
     or might reasonably be expected to, result in the disposition (whether by
     actual disposition or effective economic disposition due to cash settlement
     or otherwise) by the Company or any affiliate of the Company or any person
     in privity with the Company or any affiliate of the Company) directly or
     indirectly, including the filing (or participation in the filing) of a
     registration statement with the Commission in respect of, or establish or
     increase a put equivalent position or liquidate or decrease a call
     equivalent position within the meaning of Section 16 of the Exchange Act,
     any other shares of Common Stock or any securities convertible into, or
     exercisable, or exchangeable for, shares of Common Stock; or publicly
     announce an intention to effect any such transaction, for a period of 180
     days after the date of the Underwriting Agreement, provided, however, that
                                                        --------  -------
     (i) the Company may issue and sell Common Stock pursuant to any director or
     employee stock plan of the Company in effect at the Execution Time, and may
     issue options to purchase or make stock awards up to an aggregate of shares
     of Common Stock to directors, consultants or

                                                                              17

     employees outside of such plans, (ii) the Company may issue Common Stock
     issuable upon the conversion of securities or the exercise of warrants or
     options outstanding at the Execution Time and (iii) the Company may issue
     and sell, from time to time, Common Stock or securities convertible into
     Common Stock up to an aggregate amount of Common Stock equal to __% of the
     outstanding Common Stock following the offering in one or more transactions
     to acquire licenses or properties that complement or extend the Company's
     existing operations; provided further, however that with respect to clause
                          ----------------  -------
     (iii), the entity or entities acquiring such stock agree in writing to the
     same extent as the Company by the restrictions set forth in this paragraph
     5(f).

          (g)  The Company will not take, directly or indirectly, any action
     designed to or which has constituted or which might reasonably be expected
     to cause or result, under the Exchange Act or otherwise, in stabilization
     or manipulation of the price of any security of the Company to facilitate
     the sale or resale of the Securities.

          (h) The Company agrees to pay the costs and expenses relating to the
     following matters:  (i) the preparation, printing or reproduction and

     and sale of the Securities; (iv) the registration of the Securities under
     the Exchange Act and the listing of the Securities on the Nasdaq National

          encumbrance upon any property or assets of the Company or the
          Designated Subsidiaries  pursuant to, (i) the charter or by-laws of
          the Company or the Designated Subsidiaries,  (ii) the terms of any
          indenture, contract, lease, mortgage, deed of trust, note agreement,
          loan agreement or other agreement, obligation, condition, covenant or
          instrument to which the Company or the Designated Subsidiaries is a
          party or bound or to which its or their property is subject, or (iii)

          applicable to the Company or the Designated Subsidiaries of any court,
          regulatory body,
<PAGE>

                                                                              21

          administrative agency, governmental body, arbitrator or other
          authority having jurisdiction over the Company or the Designated
          Subsidiaries or any of its or their properties; and

               (x) no holders of securities of the Company have rights to the
          registration of such securities under the Registration Statement that
          have not been waived.

In rendering such opinion, such counsel may rely (A) as to matters involving the
application of laws other than those of The Commonwealth of Massachusetts, the
Delaware General Corporation Law or the Federal laws of the United States, to
the extent they deem proper and specified in such opinion, upon the opinion of
other counsel of good standing whom they believe to be reliable and who are
satisfactory to counsel for the Underwriters and (B) as to matters of fact, to
the extent they deem proper, on certificates or representations of responsible
officers of the Company and public officials.  References to the Prospectus in
this paragraph (b) include any supplements thereto at the Closing Date.

          In addition, such counsel shall deliver a statement to the effect
     that, subject to customary exceptions, such counsel has participated in the
     preparation of the Registration Statement and the Prospectus, including
     review and discussion of the contents thereof, and nothing has come to such
     counsel's attention that has caused it to believe that (i) the Registration
     Statement at the time the Registration Statement became effective under the
     Act (but after giving effect to any modifications incorporated therein
     pursuant to Rule 430A under the Act) and the date of such opinion contained
     or contains any untrue statement of a material fact or omitted to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading or (ii) the Prospectus, as of its date
     and the date of such opinion, contained or contains any untrue statement of
     a material fact or omitted to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; it being understood that such counsel express no
     comment with respect to the financial statements and the notes thereto and
     the schedules and other financial and statistical data (including, without
     limitation, summary or selected financial information) included in the
     Registration Statement or the Prospectus.

          (c)  The Company shall have requested and caused McConnell Valdes,
     special Puerto Rico counsel for the Company, to have furnished to the
     Representatives their opinion, dated the Closing Date and addressed to the
     Representatives, to the effect that:

               (i) each of TeleCorp Puerto Rico, Inc. and TeleCorp Puerto Rico
          Reality, Inc. (the "Puerto Rico Subsidiaries") has been duly
          incorporated and is validly existing as a corporation in good standing
          under the laws of Puerto Rico, with full corporate power and authority
          to own or lease, as the case may be, and to operate its properties and
          conduct its business as presently conducted[, and is duly qualified to
          do business as a foreign corporation and is in good standing under the
          laws of [list any]];

               (ii) all the outstanding shares of capital stock of each of the
          Puerto Rico Subsidiaries have been duly and validly authorized and
          issued and are fully paid and nonassessable;

               (iii) neither the issue and sale of the Securities, nor the
          consummation of any other of the transactions herein contemplated nor
          the fulfillment of the terms hereof will conflict with, result in a
          breach or violation of or imposition of any lien, charge or
          encumbrance upon any property or assets of the Puerto Rico
          Subsidiaries pursuant to (i) the charter or by-laws of the Puerto Rico
          Subsidiaries, (ii) the terms of any indenture, contract, lease,
          mortgage, deed of trust, note agreement, loan agreement or other
          agreement, obligation, condition, covenant or instrument to which
          either of the Puerto Rico Subsidiaries is a party or bound or to which
          their property is subject, or (iii) any statute, law, rule,
          regulation, judgment, order or decree applicable to the Puerto Rico
          Subsidiaries of any court, regulatory body, administrative agency,
          governmental body, arbitrator or other authority having jurisdiction
          over the Puerto Rico subsidiaries or any of its or their properties.

          (d)  The Company shall have  requested and caused Wiley, Rein &
     Fielding, special telecommunications counsel to the Company, to have
     furnished to the Representatives their written opinion, dated the Closing
     Date and addressed to the Representatives, in form and substance reasonably
     satisfactory to the Representatives.

          (e)  The Representatives shall have received from Cravath, Swaine &
     Moore, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date and addressed to the Representatives, with respect to the
     issuance and sale of the Securities, the Registration Statement, the
     Prospectus (together with any supplement thereto) and other related matters
     as the Representatives may
<PAGE>

                                                                              23

     reasonably require, and the Company shall have furnished to such counsel
     such documents as they request for the purpose of enabling them to pass
     upon such matters.

          (f)  The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chief Executive Officer and the
     Executive Vice President and Chief Financial Officer of the Company, dated
     the Closing Date, to the effect that the signers of such certificate have
     carefully examined the Registration Statement, the Prospectus, any
     supplements to the Prospectus and this Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

               (ii) [to the Company's knowledge], no stop order suspending the
          effectiveness of the Registration Statement has been issued and no
          proceedings for that purpose have been instituted or[, to the
          Company's knowledge,] threatened; and

               (iii) since the date of the most recent financial statements
          included in the Prospectus (exclusive of any supplement thereto),
          there has been no material adverse effect on the condition (financial
          or otherwise), prospects, earnings, business or properties of the
          Company and its subsidiaries, taken as a whole, whether or not arising
          from transactions in the ordinary course of business, except as set
          forth in or contemplated in the Prospectus (exclusive of any
          supplement thereto).

                                                                              24

          (g)  The Company shall have requested and caused
     PricewaterhouseCoopers LLP to have furnished to the Representatives, at the
     Execution Time and at the Closing Date, letters, dated respectively as of
     the Execution Time and as of the Closing Date, in form and substance
     satisfactory to the Representatives, confirming that they are independent
     accountants within the meaning of the Act and the applicable rules and
     regulations adopted by the Commission thereunder, and stating in effect
     that:

               (i) in their opinion the audited financial statements and
          financial statement schedules and pro forma financial statements
          included in the Registration Statement and the Prospectus and reported
          on by them comply as to form in all material respects with the
          applicable accounting requirements of the Act and the related rules
          and regulations adopted by the Commission;

               (ii) on the basis of carrying out certain specified procedures
          (but not an examination in accordance with generally accepted auditing
          standards) which would not necessarily reveal matters of significance
          with respect to the comments set forth in such letter; a reading of
          the minutes of the meetings of the stockholders, directors and
          executive, audit and compensation committees of the Company and the
          Subsidiaries; and inquiries of certain officials of the Company who
          have responsibility for financial and accounting matters of the
          Company and its subsidiaries as to transactions and events subsequent
          to September 30, 1999, nothing came to their attention which caused
          them to believe that:

                    (1) with respect to the period subsequent to September 30,
               1999, there were any changes, at a specified date not more than
               five days prior to the date of the letter, in the long-term debt
               of the Company and its subsidiaries or capital stock of the
               Company or decreases in the stockholders' equity of the Company
               as compared with the amounts shown on the September 30, 1999
               consolidated balance sheet included in the Registration Statement
               and the Prospectus, or for the period from October 1, 1999 to
               such specified date there were, as compared with the
               corresponding period in the preceding quarter, any decrease in
               total revenues or any increase in the total or per share amount
               of net loss of the Company, except in all instances for changes
               or decreases set forth in such letter, in which case the letter
               shall be accompanied by an explanation by the Company as to the
               significance thereof unless said explanation is not deemed
               necessary by the Representatives; or
<PAGE>

                                                                              25

                    (2) the information included in the Registration Statement
               and Prospectus in response to Regulation S-K, Item 301 (Selected
               Financial Data), and Item 402 (Executive Compensation) is not in
               conformity with the applicable disclosure requirements of
               Regulation S-K; and

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Registration Statement and the Prospectus, including the
          information set forth under the captions in the Prospectus, agrees
          with the accounting records of the Company and its subsidiaries,
          excluding any questions of legal interpretation.

     References to the Prospectus in this paragraph (f) include any supplement
     thereto at the date of the letter.

          (h)  The Company shall have received from PricewaterhouseCoopers LLP
     (and furnished to the Representatives) a report with respect to a review of
     unaudited interim financial information of the Company for the nine-month
     period ended September 30, 1998, in accordance with Statement on Auditing
     Standards No. 71.

          (i)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Prospectus (exclusive of any supplement
     thereto), there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (f) of this Section 6 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the condition (financial or otherwise), earnings, business or
     properties of the Company and its subsidiaries taken as a whole, whether or
     not arising from transactions in the ordinary course of business, except as
     set forth in or contemplated in the Prospectus (exclusive of any supplement
     thereto) the effect of which, in any case referred to in clause (i) or (ii)
     above, is, in the sole judgment of the Representatives, so material and
     adverse as to make it impractical or inadvisable to proceed with the
     offering or delivery of the Securities as contemplated by the Registration
     Statement (exclusive of any amendment thereof) and the Prospectus
     (exclusive of any supplement thereto).

          (j)  Prior to the Closing Date, the Company shall have furnished to
     the Representatives such further information, certificates and documents as
     the Representatives may reasonably request.
<PAGE>

                                                                              26

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancelation shall be given to the Company in writing or by telephone or
facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be
delivered at the office of Cravath, Swaine & Moore, counsel for the
Underwriters, at Worldwide Plaza, 825 Eighth Avenue, New York, NY 10019, on the
Closing Date.

          7.  Reimbursement of Underwriters' Expenses.  If the sale of the
              ----------------------------------------
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
[because of any termination pursuant to Section 10 hereof or ]because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through Salomon Smith Barney on demand for all out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.

          8.  Indemnification and Contribution.  (a)  The Company agrees to
              ---------------------------------
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement for the registration of
the Securities as originally filed or in any amendment thereof, or in any
Preliminary Prospectus or the Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
                                               --------  -------
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any Underwriter through the
<PAGE>

                                                                              27

Representatives specifically for inclusion therein; and provided further,
                                                        -------- -------
however, that the Company shall not be liable to any Underwriter under this
- -------
paragraph of Section 7 to the extent that any such loss, claim, damage or
liability results solely from an untrue statement of a material fact contained
in, or the omission of a material fact from, a Preliminary Prospectus if (i)
such untrue statement or omission was completely corrected in the Prospectus
prior to the written confirmation of the sale of the Securities giving rise to
such liability, (ii) such Underwriter sold Securities to the person alleging
such loss, claim, damage or liability without (to the extent required by
applicable law) sending or giving the Prospectus at or prior to the written
confirmation of the sale of the Securities giving rise to such liability, (iii)
the Company had furnished copies of the Prospectus to such Underwriter prior to
the written confirmation of the sale of the Securities giving rise to such
liability and (iv) such Underwriter would not have been subject to such
liability if it had delivered the Prospectus to such person at or prior to the
written confirmation of such sale. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

          (b)  Each Underwriter severally and not jointly agrees to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signs the Registration Statement, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company acknowledges that the
statements set forth (i) in the last paragraph of the cover page regarding
delivery of the Securities and (i) under the heading "Underwriting" (A) the list
of Underwriters and their respective participation in the sale of the
Securities, (B) the sentences related to concessions and reallowances and (C)
the paragraph related to stabilization, syndicate covering transactions and
penalty bids in any Preliminary Prospectus and the Prospectus constitute the
only information furnished in writing by or on behalf of the several
Underwriters for inclusion in any Preliminary Prospectus or the Prospectus.

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at
<PAGE>

                                                                              28

the indemnifying party's expense to represent the indemnified party in any
action for which indemnification is sought (in which case the indemnifying party
shall not thereafter be responsible for the fees and expenses of any separate
counsel retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
- --------  -------
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

          (d)  In the event that the indemnity provided in paragraph (a) or  (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
- --------  -------
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder.  If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company shall be deemed to be equal
<PAGE>

                                                                              29

to the total net proceeds from the offering (before deducting expenses) received
by it, and benefits received by the Underwriters shall be deemed to be equal to
the total underwriting discounts and commissions, in each case as set forth on
the cover page of the Prospectus. Relative fault shall be determined by
reference to, among other things, whether any untrue or any alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information provided by the Company on the one hand or
the Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

          9.  Default by an Underwriter.  If any one or more Underwriters shall
              --------------------------
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
          --------  -------
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Company.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Prospectus or in any
other documents or arrangements may be effected.  Nothing contained in this
Agreement shall

                                                                              30

relieve any defaulting Underwriter of its liability, if any, to the Company and
any nondefaulting Underwriter for damages occasioned by its default hereunder.

          10.  Termination.  This Agreement shall be subject to termination in
               ------------
the absolute discretion of the Representatives, by notice given to the Company
prior to delivery of and payment for the Securities, if at any time prior to
such time (i) trading in the Company's Common Stock shall have been suspended by
the Commission or the Nasdaq National Market or trading in securities generally
on the New York Stock Exchange or the Nasdaq National Market shall have been
suspended or limited or minimum prices shall have been established on such
Exchange or the Nasdaq National Market, (ii) a banking moratorium shall have
been declared either by Federal or New York State authorities or (iii) there
shall have occurred any outbreak or escalation of hostilities, declaration by
the United States of a national emergency or war, or other calamity or crisis
the effect of which on financial markets is such as to make it, in the sole
judgment of the Representatives, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Prospectus
(exclusive of any supplement thereto).

          11.  Representations and Indemnities to Survive. The respective
               -------------------------------------------
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

          13.  Successors.  This Agreement will inure to the benefit of and be
               -----------
binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 8 hereof, and no other person will have any right or obligation
hereunder.

          14.  Applicable Law.  This Agreement will be governed by and construed
               ---------------
in accordance with the laws of the State of New York applicable to contracts
made and to be performed within the State of New York.

Series A Preferred Stock pursuant to this Section 4.3(b) shall be paid pro rata
to the holders entitled thereto. In the event that the funds legally available

  (c)    Certain Restrictions.
         --------------------

  (i)    Notwithstanding the provisions of Sections 4.3(b), (e) and (f), cash
dividends on the Series A Preferred Stock may not be declared, paid or set apart
for payment, nor may the Corporation redeem, purchase or otherwise acquire any
shares of Series A Preferred Stock, if (A) the Corporation is not solvent or
would be rendered insolvent thereby or (B) at such time the terms and provisions
of any law or agreement of the Corporation, including any agreement relating to
its indebtedness, specifically prohibit such declaration, payment or setting
apart for payment or such redemption, purchase or other acquisition, or provide
that such declaration, payment or setting apart for payment or such redemption,
purchase or other acquisition would constitute a violation or breach thereof or
a default thereunder.

  (ii)   So long as shares of Series A Preferred Stock are outstanding or
dividends payable on shares of Series A Preferred Stock have not been paid in
full in cash, then the Corporation shall not declare or pay cash dividends on,
or redeem, purchase or otherwise acquire for consideration, any shares of Common
Stock or other shares of Junior Stock, except with the prior written consent of
holders of a majority of the outstanding shares of Series A Preferred Stock,
except that the Corporation may acquire, in accordance with the terms of any
agreement between the Corporation and its employees, shares of Common Stock or
Preferred Stock at a price not greater than the Market Price as of such date.

  (iii)  The Corporation shall not permit any Subsidiary of the Corporation, or
cause any other Person, to make any distribution with respect to, or purchase or
otherwise acquire for consideration, any shares of capital stock of the
Corporation, unless the Corporation could, pursuant to paragraph (ii) above,
make such distribution or purchase or otherwise acquire such shares at such time
and in such manner.

such matters (other than the matters described in paragraphs (ii) and (iii)
below or as otherwise required by law).

                                      -5-
<PAGE>

  (ii)   Unless the consent or approval of a greater number of shares shall then
be required by law, the affirmative vote of the holders of a majority of the
outstanding shares of Series A Preferred Stock in person or by proxy, at each
special and annual meeting of stockholders called for the purpose, or by written
consent, shall be necessary to (A) authorize, increase the authorized number of
shares of or issue (including on conversion or exchange of any convertible or
exchangeable securities or by reclassification) any shares of any class or
classes of Senior Stock or Parity Stock or any additional shares of Series A
Preferred Stock, (B) authorize, adopt or approve each amendment to this Restated
Certificate of Incorporation that would increase or decrease the par value of
the shares of Series A Preferred Stock, alter or change the powers, preferences
or rights of the shares of Series A Preferred Stock or alter or change the
powers, preferences or rights of any other capital stock of the Corporation if
such alteration or change results in such capital stock being Senior Stock or
Parity Stock, (C) amend, alter or repeal any provision of this Restated
Certificate of Incorporation so as to affect the shares of Series A Preferred
Stock adversely, or (D) authorize or issue any security convertible into,
exchangeable for or evidencing the right to purchase or otherwise receive any
shares of any class or classes of Senior Stock or Parity Stock.

  (iii)  So long as the Initial Holders own in the aggregate at least two-thirds
(2/3) of the number of shares of Series A Preferred Stock owned by them on July
17, 1998, holders of shares of Series A Preferred Stock shall have the exclusive
right, voting separately as a single class, to nominate one director of the
Corporation. The foregoing right to nominate one director may be exercised at
any annual meeting of stockholders or a special meeting of stockholders or
holders of Series A Preferred Stock held for such purpose or any adjournment
thereof, or by the written consent, delivered to the Secretary of the
Corporation, of the holders of a majority of the issued and outstanding shares
of Series A Preferred Stock. Notwithstanding the foregoing, the Initial Holders
shall have the right, exercisable at any time by written notice delivered to the
Secretary of the Corporation, to surrender and cancel irrevocably such right to
nominate one director of the Corporation. So long as the Initial Holders own in
the aggregate at least two-thirds (2/3) of the number of shares of Series A
Preferred Stock owned by them on July 17, 1998, in the event any director so
nominated by the Initial Holders ceases to be a director of the Corporation
during such director's term (whether or not such director resigns, is removed
from the Board of Directors with or without cause or ceases to be a director by
reason of death, disability or for any other reason), the Initial Holders shall
have the right to designate a replacement for such director, and the Corporation
shall cause to be elected or appointed for the remainder of the term of any
director so replaced any person designated by the Initial Holders, upon written
notice to the Corporation and the other members of the Board of Directors which
notice shall set forth the name of the member being replaced and the name of the
new member.

  (e) Redemption at Option of the Corporation.  The Corporation shall have the
      ---------------------------------------
right to redeem shares of Series A Preferred Stock pursuant to the following
provisions:

  (i) The Corporation shall not have any right to redeem shares of the Series A

<PAGE>

30th day after the tenth anniversary of the issuance of such share.
Thereafter, subject to the restrictions in Section 4.3(c)(i), the Corporation
shall have the right, at its sole option and election, to redeem the shares of
the Series A Preferred Stock, in whole but not in part, at any time at a
redemption price (the "Series A Redemption Price") per share equal to the
                       -------------------------
Liquidation Preference as of the redemption date;

  (ii)   Notice of any redemption of the Series A Preferred Stock shall be
mailed at least ten, but not more than 60, days prior to the date fixed for

facilitate the redemption of the Series A Preferred Stock, the Board of
Directors may fix a record date for the determination of holders of Series A
Preferred Stock to be redeemed, or may cause the transfer books of the
Corporation to be closed for the transfer of the Series A Preferred Stock, not
more than 60 days prior to the date fixed for such redemption;

  (iii)  Within two Business Days after the redemption date specified in the
notice given pursuant to paragraph (ii) above and the surrender of the
certificate(s) representing shares of Series A Preferred Stock, the Corporation
shall pay to the holder of the shares being redeemed the Series A Redemption
Price therefor. Such payment shall be made by wire transfer of immediately
available funds to an account designated by such holder or by overnight delivery
(by a nationally recognized courier) of a bank check to such holder's address as
it appears on the books of the Corporation; and

  (iv)   Effective upon the date of the notice given pursuant to paragraph (ii)
above, notwithstanding that any certificate for such shares shall not have been
surrendered for cancellation, the shares represented thereby shall no longer be
deemed outstanding, the rights to receive dividends thereon shall cease to
accrue from and after the date of redemption designated in the notice of
redemption and all rights of the holders of the shares of the Series A Preferred
Stock called for redemption shall cease and terminate, excepting only the right
to receive the Series A Redemption Price therefor in accordance with paragraph
(iii) above and the right to convert such shares into shares of Class A Common
Stock until the close of business on the third Business Day preceding the
redemption date, as provided in Section 4.3(i).

  (f)    Redemption at Option of Holder.
         ------------------------------

  (i)    No holder of shares of Series A Preferred Stock shall have any right to
require the Corporation to redeem any shares of Series A Preferred Stock prior
to, with respect to any share of the Series A Preferred Stock, the 30th day
after the twentieth anniversary of the issuance of such share.  Thereafter,
subject to the restrictions set forth in Section 4.3(c)(i), each holder of
shares of Series A Preferred Stock shall have the right, at the sole option and
election of such holder, to require the Corporation to redeem all (but not less
than all) of the shares of Series A Preferred Stock owned by such holder at a
price per share equal to the Series A Redemption Price;

  (ii)   The holder of any shares of the Series A Preferred Stock may exercise

                                      -7-

such holder's right to require the Corporation to redeem such shares by
surrendering for such purpose to the Corporation, at its principal office or at
such other office or agency maintained by the Corporation for that purpose,
certificates representing the shares of Series A Preferred Stock to be redeemed,
accompanied by a written notice stating that such holder elects to require the
Corporation to redeem all (but not less than all) of such shares in accordance
with the provisions of this Section 4.3(f), which notice may specify an account
for delivery of the Series A Redemption Price;

  (iii)  Within two Business Days after the surrender of such certificates, the
Corporation shall pay to the holder of the shares being redeemed the Series A
Redemption Price therefor.  Such payment shall be made by wire transfer of
immediately available funds to an account designated by such holder or by
overnight delivery (by a nationally recognized courier) of a bank check to such
holder's address as it appears on the books of the Corporation; and

  (iv)   Such redemptions shall be deemed to have been made at the close of
business on the date of the receipt of such notice and of such surrender of the
certificates representing the shares of the Series A Preferred Stock to be
redeemed and the rights of the holder thereof, except for the right to receive

respect to each share of Series A Preferred Stock.

  (ii)   If, upon any liquidation, dissolution or winding up of the Corporation,
the assets of the Corporation available for distribution to the holders of

holders of the sums which such holders are entitled to receive in such case,
then all of the assets available for distribution to holders of the Series A
Preferred Stock and Series B Preferred Stock shall be distributed among and paid
to such holders ratably in proportion to the amounts that would be payable to

other Person nor the sale or other distribution to another Person of all or
substantially all the assets, property or business of the Corporation, shall be
deemed to be a liquidation, dissolution or winding up of the Corporation for
purposes of this Section 4.3(h).

  (i) Conversion.
      ----------

  (i)   Stockholders' Right To Convert.  No holder of shares of Series A
        ------------------------------
Preferred Stock shall have any right to convert any shares of Series A Preferred
Stock into Class A Common Stock or any other securities of the Corporation prior
to July 17, 2006. Thereafter, each share of Series A Preferred Stock held by the
Initial Holders or a Qualified Transferee shall be convertible, at the sole
option and election of the Initial Holders or Qualified Transferee, into fully
paid and non-assessable shares of Class A Common Stock.

  (ii)  Number of Shares of Class A Common Stock Issuable upon Conversion.  The
        -----------------------------------------------------------------
number of shares of Class A Common Stock to be issued upon conversion of shares
of Series A Preferred Stock pursuant to paragraph (i) above shall be equal to
the product of (A) the Series A Conversion Rate as of the date of the applicable
notice pursuant to paragraph (iv) below, multiplied by (B) the number of shares
of Series A Preferred Stock to be converted.

  (iii) Fractional Shares.  Notwithstanding any other provision of this Restated
        -----------------
Certificate of Incorporation, the Corporation shall not be required to issue
fractions of shares upon conversion of any shares of Series A Preferred Stock or
to distribute certificates which evidence fractional shares.  In lieu of
fractional shares, the Corporation may pay therefor, at the time of any
conversion of shares of Series A Preferred Stock as herein provided, an amount
in cash equal to such fraction multiplied by the Market Price of a share of
Class A Common Stock on such date.

  (iv)  Mechanics of Conversion.  The Initial Holders or Qualified Transferee
        -----------------------
may exercise its option to convert by surrendering for such purpose to the
Corporation, at its principal office or such other office or agency maintained
by the Corporation for that purpose, certificates representing the shares of
Series A Preferred Stock to be converted, accompanied by a written notice,
delivered in accordance with the terms of the Stockholders Agreement, stating
that such holder elects to convert such shares in accordance with this Section
4.3(i). The date of receipt of such certificates and notice by the Corporation
at such office shall be the conversion date (the "Series A Conversion Date").
                                                  ------------------------
If required by the Corporation, certificates surrendered for conversion shall be
endorsed or accompanied by a written instrument or instruments of transfer, in
form satisfactory to the Corporation, duly executed by the registered holder or
his or its attorney duly authorized in writing.  Within ten Business Days after
the Series A Conversion Date (or, if at the time of such surrender the shares of
Class A Common Stock are not listed or admitted for trading on any national
securities exchange and are not quoted on NASDAQ or any similar service, within
ten Business Days of the determination of the Market Price pursuant to the
Appraisal Procedure), the Corporation shall issue to such holder a number of
shares of Class A Common Stock into which such shares of Series A Preferred
Stock are convertible pursuant to paragraph (ii) above.  Certificates
representing such shares of Class A Common Stock

                                      -9-
<PAGE>

shall be delivered to such holder at such holder's address as it appears on the
books of the Corporation.

  (v)    Termination of Rights.  All shares of Series A Preferred Stock which
         ---------------------
shall have been surrendered for conversion as herein provided shall no longer be
deemed to be outstanding and all rights with respect to such shares, including
the rights, if any, to receive notices and to vote, shall immediately cease and
terminate on the Series A Conversion Date, except only the right of the holders
thereof to receive shares of Class A Common Stock in exchange therefor and
payment of any declared and unpaid dividends thereon.

  (vi)   No Conversion Charge or Tax.  The issuance and delivery of
         ---------------------------
certificates for shares of Class A Common Stock upon the conversion of shares of
Series A Preferred Stock shall be made without charge to the holder of shares of
Series A Preferred Stock for any issue or transfer tax, or other incidental
expense in respect of the issuance or delivery of such certificates or the
securities represented thereby, all of which taxes and expenses shall be paid by
the Corporation.

  (vii)  Reorganization, Reclassification and Merger Adjustment.  If there
         ------------------------------------------------------
occurs any capital reorganization or any reclassification of the Class A Common
Stock of the Corporation, the consolidation or merger of the Corporation with or
into another Person (other than a merger or consolidation of the Corporation in
which the Corporation is the continuing corporation and which does not result in
any reclassification or change of outstanding shares of its Class A Common
Stock) or the sale or conveyance of all or substantially all of the assets of
the Corporation to another Person, then each share of Series A Preferred Stock
shall thereafter be convertible into the same kind and amounts of securities
(including shares of stock) or other assets, or both, which were issuable or
distributable to the holders of outstanding Class A Common Stock of the
Corporation upon such reorganization, reclassification, consolidation, merger,
sale or conveyance, in respect of that number of shares of Class A Common Stock
into which such share of Series A Preferred Stock might have been converted
immediately prior to such reorganization, reclassification, consolidation,
merger, sale or conveyance; and, in any such case, appropriate adjustments (as
determined in good faith by the Board of Directors of the Corporation, whose
determination shall be conclusive) shall be made to assure that the provisions
set forth herein shall thereafter be applicable, as nearly as reasonably may be
practicable, in relation to any securities or other assets thereafter
deliverable upon the conversion of the Series A Preferred Stock.

  (viii) Notice of Adjustment.  Whenever the securities or other property
         --------------------
deliverable upon the conversion of the Series A Preferred Stock shall be
adjusted pursuant to the provisions hereof, the Corporation shall promptly give
written notice thereof to each holder of shares of Series A Preferred Stock at
such holder's address as it appears on the transfer books of the Corporation and
shall forthwith file, at its principal executive office and with any transfer
agent or agents for the Series A Preferred Stock and the Class A Common Stock, a
certificate, signed by the Chairman of the Board,

                                      -10-
<PAGE>

President or one of the Vice Presidents of the Corporation, and by its Chief
Financial Officer, Treasurer or one of its Assistant Treasurers, stating the
securities or other property deliverable per share of Series A Preferred Stock
calculated to the nearest cent or to the nearest one-hundredth of a share and
setting forth in reasonable detail the method of calculation and the facts
requiring such adjustment and upon which such calculation is based. Each
adjustment shall remain in effect until a subsequent adjustment hereunder is
required.

  (ix)   Reservation of Class A Common Stock.  The Corporation shall at all
         -----------------------------------
times reserve and keep available for issuance upon the conversion of the shares
of Series A Preferred Stock the maximum number of its authorized but unissued
shares of Class A Common Stock as is reasonably anticipated to be sufficient to
permit the conversion of all outstanding shares of Series A Preferred Stock, and
shall take all action required to increase the authorized number of shares of
Class A Common Stock if at any time there shall be insufficient authorized but
unissued shares of Class A Common Stock to permit such reservation or to permit
the conversion of all outstanding shares of Series A Preferred Stock.

  (j)    Qualified Transfer.  If at any time an Initial Holder or Qualified
         ------------------
Transferee desires to sell, transfer or otherwise dispose of shares of Series A
Preferred Stock pursuant to a Qualified Transfer, it shall, with respect to each
such proposed transfer, give written notice (a "Qualified Transfer Notice") to
                                                -------------------------
the Corporation at its principal executive office specifying up to ten
prospective transferees. Upon receipt of such notice, the Corporation shall have
ten days to give written notice to the Initial Holders or Qualified Transferee
specifying its disapproval of (A) any or all of such prospective transferees if
it has good reason for such disapproval and specifying such reason and (B) up to
two of such prospective transferees with or without good reason.

  (k)    Notice of Certain Events. In case the Corporation shall propose at any
         ------------------------
time or from time to time (i) to declare or pay any dividend payable in stock of
any class to the holders of Common Stock or to make any other distribution to
the holders of Common Stock, (ii) to offer to the holders of Common Stock rights
or warrants to subscribe for or to purchase any additional shares of Common
Stock or shares of stock of any class or any other securities, rights or

effect any consolidation, merger or sale, transfer or other disposition of all
or substantially all of the property, assets or business of the Corporation
which would, if consummated, adjust the Series A Conversion Rate or the
securities issuable upon conversion of shares of Series A Preferred Stock, or
(v) to effect the liquidation, dissolution or winding up of the Corporation,
then, in each such case, the Corporation shall mail to each holder of shares of
Series A Preferred Stock, at such holder's address as it appears on the transfer
books of the Corporation, a written notice of such proposed action, which shall
specify (A) the date on which a record is to be taken for the purpose of such
dividend or distribution of rights or warrants or, if a record is not to be
taken, the date as of which the holders of shares of Common Stock of record to
be entitled to such dividend or distribution of rights or warrants are to be
determined, or (B) the date on which such reclassification, consolidation,
merger, sale, conveyance, dissolution,

                                      -11-
<PAGE>

prior to the applicable record, determination or effective date, specified in
such notice.

         ----------------

authorized (other than Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, or
Common Stock), with respect to the payment of dividends and the distribution of
assets on liquidation, dissolution and winding up.

  (b) Dividends. Holders of Series F Preferred Stock shall be entitled to
      ---------
dividends in cash or property when, as and if, declared by the Board of
Directors of the Corporation.

  (c) Liquidation Preference.
      ----------------------

    (i)   In the event of any liquidation, dissolution or winding up of the
Corporation, the holders of Series F Preferred Stock shall be entitled to
receive out of the assets of the Corporation, whether such assets are capital or
surplus of any nature, after payment is made to holders of all series of
preferred stock ranking senior to the Series F Preferred Stock with respect to
rights on liquidation, dissolution or winding up, but before any payment shall
be made or any assets distributed to the holders of Common Stock or any series
of preferred stock ranking junior to the Series F Preferred Stock with respect
to rights on liquidation, dissolution or winding up, an amount equal to the
Liquidation Preference and no more.

    (ii)  If upon any liquidation, dissolution or winding up of the Corporation
the assets of the Corporation to be distributed are insufficient to permit the
payment to all holders of Series F Preferred Stock and any other series of
preferred stock ranking on a parity with Series F Preferred Stock with respect
to rights on liquidation, dissolution or winding up, to receive their full
preferential amounts, the entire assets of the Corporation shall be distributed
among the holders of Series F Preferred Stock and all such other series ratably
in accordance with their respective Liquidation Preference.

    (iii) After payment to the holders of Series F Preferred Stock of the
amounts set forth in paragraph (i) above, the entire remaining assets and funds
of the Corporation legally available for distribution, if any, shall be
distributed among the holders of the Participating Stock in proportion to the
shares of Participating Stock then held by them as of the date of the
liquidation, dissolution or winding up of the Corporation.

    (iv)  Neither the consolidation or merger of the Corporation with or into
any other Person nor the sale or other distribution to another Person of all or
substantially all the assets, property or business of the Corporation, shall be
deemed to be a liquidation, dissolution or winding up of the Corporation for
purposes of this Section 4.8(c).

  (d) Voting Rights.
      -------------

    (i)   The holders of shares of Series F Preferred Stock shall not have any
right to vote on any matters to be voted on by the stockholders of the
Corporation, except as otherwise provided in paragraph (ii) below or as provided
by law, and the shares of Series F Preferred Stock shall not be included in
determining the number of shares voting or

                                      -18-
<PAGE>

entitled to vote on any such matters (other than the matters described in
paragraph (ii) below or as otherwise required by law).

  (ii)  The affirmative vote of holders of not less than a majority of Series
F Preferred Stock shall be required to (A) authorize, increase the authorized
number of shares of or issue (including on conversion or exchange of any
convertible or exchangeable securities or by reclassification) any shares of any
class or classes of stock ranking senior to or pari passu with the Series F
Preferred Stock or any additional shares of Series F Preferred Stock, (B)
authorize, adopt or approve each amendment to this Restated Certificate of
Incorporation that would increase or decrease the par value of the shares of
Series F Preferred Stock, alter or change the powers, preferences or rights of
the shares of Series F Preferred Stock or alter or change the powers,
preferences or rights of any other capital stock of the Corporation if such
alteration or change results in such capital stock ranking senior to or pari
passu with the Series F Preferred Stock, (C) amend, alter or repeal any
provision of this Restated Certificate of Incorporation so as to affect the
shares of Series F Preferred Stock adversely, or (D) authorize or issue any
security convertible into, exchangeable for or evidencing the right to purchase
or otherwise receive any shares of any class or classes of stock senior to or
pari passu with the Series F Preferred Stock.

  (e) Conversion. The shares of Series F Preferred Stock shall be convertible
      ----------
into shares of Common Stock as follows:

  (i)   Optional Conversion.  Each share of Series F Preferred Stock shall be
        -------------------
convertible, at the option of the holder thereof, at any time and from time to
time, into one fully paid and non-assessable share of Non-Tracked Common Stock;
provided that, unless and until the Tracked Common Stock shall be convertible
into Class A Common Stock in accordance with Section 4.9(e)(i), each of the
first 63,127 shares of Series F Preferred Stock converted pursuant to this
paragraph shall be convertible into one fully paid and non-assessable share of
Class D Common Stock.

  (ii)  Mechanics of Optional Conversion. In order for a holder of Series F
        --------------------------------
Preferred Stock to convert such shares into shares of Common Stock, such holder
shall surrender the certificate(s) for such shares of Series F Preferred Stock
at the office of the transfer agent for the Series F Preferred Stock (or if the
Corporation serves as its own transfer agent, at the principal office of the
Corporation), together with written notice that such holder elects to convert
all or any number of the shares of the Series F Preferred Stock represented by
such certificate(s). If required by the Corporation, certificates surrendered
for conversion shall be endorsed or accompanied by a written instrument or
instruments of transfer, in form satisfactory to the Corporation, duly executed
by the registered holder or his or its attorney duly authorized in writing. The
date of receipt of such certificates and notice by the transfer agent (or by the
Corporation if the Corporation serves as its own transfer agent) shall be the
conversion date (the "Optional Conversion Date"). The Corporation shall, within
                      ------------------------
ten Business Days after the Optional Conversion Date, issue and deliver at such
office to such holder of Series F Preferred Stock, or to his or its nominees,
one or more certificates for the number of whole shares of Common

                                      -19-
<PAGE>

Stock (and any shares of Series F Preferred Stock represented by the certificate
delivered to the Corporation by the holder thereof that are not converted into
Common Stock) issuable upon such conversion in accordance with the provisions
hereof.

  (iii) Reservation of Shares. The Corporation shall at all times when the
        ---------------------
Series F Preferred Stock shall be outstanding, reserve and keep available out of
its authorized but unissued stock, for the purpose of effecting the conversion
of the Series F Preferred Stock, such number of its duly authorized shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of Series F Preferred Stock. Before taking any action
which would cause Common Stock upon the conversion of Series F Preferred Stock,
to be issued below the then par value of the shares of Common Stock the
Corporation will take any corporate action that may, in the opinion of its
counsel, be necessary in order that the Corporation may validly and legally
issue fully paid and non-assessable shares of Common Stock, as the case may be,
to the holders of Series F Preferred Stock.

  (iv)  Adjustments for Dividends. Upon any conversion of Series F Preferred
        -------------------------
Stock, no adjustment to the conversion ratio shall be made for declared and
unpaid dividends on the Series F Preferred Stock surrendered for conversion or
on the Common Stock delivered upon conversion.

  (v)   Termination of Rights. All shares of Series F Preferred Stock which
        ---------------------
shall have been surrendered for conversion as herein provided shall no longer be
deemed to be outstanding and all rights with respect to such shares, including
the rights, if any, to receive notices and to vote, shall immediately cease and
terminate on the Optional Conversion Date, except only the right of the holders
thereof to receive shares of Common Stock in exchange therefor and payment of
any declared and unpaid dividends thereon. On and as of the Optional Conversion
Date, the shares of Common Stock issuable upon such conversion shall be deemed
to be outstanding, and the holder thereof shall be entitled to exercise and
enjoy all rights with respect to such shares of Common Stock including the
rights, if any, to receive notices and to vote. Shares of Series F Preferred
Stock converted into Common Stock will be restored to the status of authorized
but unissued shares of Common Stock or preferred stock without designation as to
class or series, and may thereafter be issued, whether or not designated as
shares of Class A Common Stock or Series F Preferred Stock.

  (vi)  No Conversion Charge or Tax. The issuance and delivery of certificates
        ---------------------------
for shares of Common Stock upon the conversion of shares of Series F Preferred
Stock shall be made without charge to the holder of shares of Series F Preferred
Stock for any issue or transfer tax, or other incidental expense in respect of
the issuance or delivery of such certificates or the securities represented
thereby, all of which taxes and expenses shall be paid by the Corporation.

  (vii) Reorganization, Reclassification and Merger Adjustment. If there occurs
any capital reorganization or any reclassification of the Common Stock of the
Corporation, the consolidation or merger of the Corporation with or into another
Person

                                      -20-
<PAGE>

(other than a merger or consolidation of the Corporation in which the
Corporation is the continuing corporation and which does not result in any
reclassification or change of outstanding shares of its Common Stock) or the
sale or conveyance of all or substantially all of the assets of the Corporation
to another Person, then each share of Series F Preferred Stock shall thereafter
be convertible into the same kind and amounts of securities (including shares of
stock) or other assets, or both, which were issuable or distributable to the
holders of outstanding Common Stock of the Corporation upon such reorganization,
reclassification, consolidation, merger, sale or conveyance, in respect of that
number of shares of Common Stock into which such share of Series F Preferred
Stock might have been converted immediately prior to such reorganization,
reclassification, consolidation, merger, sale or conveyance; and, in any such
case, appropriate adjustments (as determined in good faith by the Board of
Directors of the Corporation, whose determination shall be conclusive) shall be
made to assure that the provisions set forth herein shall thereafter be
applicable, as nearly as reasonably may be practicable, in relation to any
securities or other assets thereafter deliverable upon the conversion of the
Series F Preferred Stock.

  (f) Certain Restrictions.
      --------------------

  (i)   Notwithstanding the provisions of Sections 4.8(b), cash dividends on the
Series F Preferred Stock may not be declared, paid or set apart for payment, nor
may the Corporation redeem, purchase or otherwise acquire any shares of Series F
Preferred Stock, if (A) the Corporation is not solvent or would be rendered
insolvent thereby or (B) at such time the terms and provisions of any law or
agreement of the Corporation, including any agreement relating to its
indebtedness, specifically prohibit such declaration, payment or setting apart
for payment or such redemption, purchase or other acquisition, or provide that
such declaration, payment or setting apart for payment or such redemption,
purchase or other acquisition would constitute a violation or breach thereof or
a default thereunder.

  (ii)  The Corporation shall not permit any Subsidiary of the Corporation, or
cause any other Person, to make any distribution with respect to, or purchase or
otherwise acquire for consideration, any shares of Common Stock or other shares
of capital stock of the Corporation ranking junior to or on a parity basis with
the Series F Preferred Stock unless the Corporation could, pursuant to paragraph
(i) above, make such distribution or purchase or otherwise acquire such shares
at such time and in such manner.

  (g) Redemption.  The Series F Preferred Stock is not redeemable.
      ----------

  (h) Sinking Fund. There shall be no sinking fund for the payment of dividends
      ------------
or Liquidation Preferences on the Series F Preferred Stock.

  4.9 Common Stock.
      ------------

  (a) General.   Except as otherwise provided herein, all shares of Common Stock
      -------
issued and outstanding shall be identical, and shall entitle the holders thereof
to the same

                                      -21-
<PAGE>

rights, powers and privileges of stockholders under Delaware law. For purposes
of this Section 4.9 (and the definitions relating thereto), the Class A Common
Stock and the Class B Common Stock are herein collectively referred to as the
"Non-Tracked Common Stock" and the Class C Common Stock and the Class D Common
Stock are herein collectively referred to as the "Tracked Common Stock".

  (b) Dividends.  Subject to Section 4.10(b) and the express terms of any
      ---------
outstanding series of Preferred Stock, dividends may be paid in cash or
otherwise with respect to each class of Common Stock out of the assets of the
Corporation, upon the terms, and subject to the limitations, provided in this
Section 4.9(b), as the Board of Directors may determine.

  (i)   Dividends on the Non-Tracked Common Stock.  Dividends on the Non-Tracked
        -----------------------------------------
Common Stock may be declared and paid only out of the excess of (A) the funds of
the Corporation legally available therefor over (B) the Tracked Business
Available Dividend Amount (the "Non-Tracked Business Available Dividend
                                ---------------------------------------
Amount").
- ------

  (ii)  Dividends on Tracked Common Stock. Dividends on the Tracked Common Stock
        ---------------------------------
may be declared and paid only out of the lesser of (A) the funds of the
Corporation legally available therefor and (B) the Tracked Business Available
Dividend Amount. The Corporation shall not declare or pay cash dividends on, or
redeem, purchase or otherwise acquire for consideration, any shares of Tracked
Common Stock unless concurrently therewith the Corporation shall declare or pay
cash dividends on, or redeem, purchase or otherwise acquire for consideration,
as the case may be, on the same terms, all shares of Tracked Common Stock
ratably in accordance with the number of shares of each class of Tracked Common
Stock then outstanding.

  (iii) Discrimination in Dividends Among the Tracked and Non-Tracked Common
        --------------------------------------------------------------------
        Stock. The Board of Directors may at any time, subject to the provisions
        ------
of Sections 4.9(b)(i) and (ii) and Section 4.10, declare and pay dividends
exclusively on the Non-Tracked Common Stock, exclusively on the Tracked Common
Stock or on both such categories of Common Stock in equal or unequal amounts,
notwithstanding the relative amounts of the Non-Tracked Business Available
Dividend Amount and the Tracked Business Available Dividend Amount.

  (c) Voting.
      ------

  (i)   The holders of shares of Common Stock shall be entitled to such voting
rights as hereinafter provided, and shall be entitled to notice of any
stockholders' meeting and to vote upon such matters as provided herein and in
the Bylaws of the Corporation, and as may be provided by law. Holders of any
class of Common Stock shall not be entitled to cumulate their votes for any
purpose. Except as otherwise required by law or provided herein, regardless of
the number of shares of any class of Common Stock then outstanding, each class
of Common Stock shall be entitled to the number of votes enumerated below and
the number of votes or fractional votes to which each share of a particular
class of Common Stock shall be entitled shall be the quotient determined by

                                      -22-
<PAGE>

dividing the aggregate number of votes to which such class of Common Stock is
entitled by the number of shares of such class of Common Stock then outstanding.
Except as otherwise required by law or provided herein, the Class A Common Stock
shall have 4,990,000 votes; the Class B Common Stock shall have no votes; the
Class C Common Stock shall have no votes; the Class D Common Stock shall have no
votes; and the Voting Preference Common Stock shall have 5,010,000 votes.

  (ii)  A quorum for the transaction of business shall be present when a
majority of the shares of Voting Preference Common Stock outstanding as of the
record date are present and when shares of all classes of Common Stock with at
least 5,010,000 votes are present, except that (x) with respect to actions
requiring a majority vote of the Class A Common Stock, the presence of a
majority of the outstanding shares of Class A Common Stock shall also be
required for a quorum to be present, (y) with respect to actions requiring the
vote of a majority vote of the Class C Common Stock, the presence of a majority
of the outstanding shares of Class C Common Stock shall also be required for a
quorum to be present and (z) with respect to actions requiring the vote of a
majority vote of the Class D Common Stock, the presence of a majority of the
outstanding shares of Class D Common Stock shall also be required for a quorum
to be present. Except as otherwise required by law or provided herein, the
majority vote of the Voting Preference Common Stock present at any meeting at
which a quorum is present shall be sufficient to approve any action required to
be approved by the holders of the Common Stock.

  (iii) In any matter requiring a separate class vote of holders of any class of
Common Stock or a separate vote of two or more classes of Common Stock voting
together as a single class, for the purposes of such a class vote, each share of
Common Stock of such classes shall be entitled to one vote per share.

  (iv)  In the event that the Corporation shall have received an opinion of
regulatory counsel of nationally recognized standing to the effect that the
rules, regulations or policies of the Federal Communications Commission (the
"FCC") permit the Class A Common Stock and the Voting Preference Common Stock
 ---
(x) to be voted as a single class on all matters, (y) to be treated as a single
class for purposes of all quorum requirements and (z) to have one vote per
share, then, unless the Board of Directors of the Corporation shall have
determined, within 30 days after the date of receipt of such opinion, that
obtaining the FCC consent described below would be reasonably expected to have a
significant detrimental effect on the Corporation, the Corporation shall, upon
the affirmative vote of 66-2/3% or more of the Class A Common Stock, seek
consent from the FCC to permit the Class A Common Stock and Voting Preference
Common Stock to vote and act as a single class in the manner described above.
From and after the date that such consent is obtained, the Class A Common Stock
and the Voting Preference Common Stock shall be voted as a single class on all
matters, shall be treated as a single class for purposes of all quorum
requirements, and shall have one vote per share; provided, that the voting
rights of the the Class B Common Stock, Class C Common Stock and Class D Common
Stock and the Preferred Stock shall remain unaffected.

  (v)   The holders of shares of Class B Common Stock shall be entitled to vote

                                      -23-
<PAGE>

as a separate class on any amendment, repeal or modification of any provision of
this Restated Certificate of Incorporation that adversely affects the powers,
preferences or special rights of the holders of the Class B Common Stock.

  (d) Dissolution, Liquidation or Winding Up. Upon the dissolution, liquidation
      --------------------------------------
or winding up of the Corporation, after any preferential amounts to be
distributed to the holders of the Preferred Stock and any other class or series
of stock having a preference over the Common Stock then outstanding have been
paid or declared and funds sufficient for the payment thereof in full set apart
for payment, (i) the holders of the Tracked Common Stock shall be entitled to
receive pro rata the Tracked Business Available Liquidation Amount and (ii) the
holders of the Non-Tracked Common Stock shall be entitled to receive pro rata
the excess of (A) all the remaining assets of the Corporation available for
distribution to its stockholders over (B) the Tracked Business Available
Liquidation Amount.

  (e) Conversion.
      ----------

  (i)   Each share of Class B Common Stock may, at the option of the holder
thereof, at any time, be converted into one fully paid and non-assessable share
of Class A Common Stock.

  (ii)  Each share of Class A Common Stock may, at the option of the holder
thereof, at any time, be converted into one fully paid and non-assessable share
of Class B Common Stock.

  (iii) In the event that the Corporation shall have received an opinion of
regulatory counsel of nationally recognized standing to the effect that the
rules, regulations or policies of the FCC permit the conversion of shares of
Tracked Common Stock into Class A Common Stock or Class B Common Stock, then,
unless the Board of Directors of the Corporation shall have determined, within
30 days after receipt of such opinion, that permitting such conversion would be
reasonably expected to have a significant detrimental effect on the Corporation,
shares of Class C Common Stock and Class D Common Stock shall, upon the
affirmative vote of 66-2/3% or more of the Class A Common Stock, be convertible
as follows: (x) each share of Class C Common Stock may, at the option of the
holder thereof, be converted into one fully paid and non-assessable share of
Class A Common Stock or or Class B Common Stock, and (y) each share of Class D

fully paid and non-assessable share of Class A Common Stock or Class B Common
Stock.

  4.10 Participating Stock.
       -------------------

  (a) Changes in Capital Stock. The Corporation shall not effect any change in
      ------------------------
or reclassification of any class or series of the outstanding Participating
Stock, whether through stock dividends, stock splits, reverse stock splits,
combinations or otherwise, without the payment to the Corporation of any
consideration therefor in money, services

                                      -24-
<PAGE>

      ---------------------------
dividends on, or redeem, purchase or otherwise acquire for consideration, any

for consideration, as the case may be, on the same terms, all shares of
Participating Stock ratably in accordance with the number of shares of each
class and series of Participating Stock then outstanding.

  (c) Notices. Any written notice or communication by the Corporation to holders
      -------
of any class or series of Participating Stock shall be sent to all holders of
Participating Stock.

  4.11 Exchange of Capital Stock.  Notwithstanding any other provision of this
       -------------------------
Restated Certificate of Incorporation to the contrary, in the event that AT&T
Wireless PCS, LLC terminates its obligations under Section 8.6 of the
Stockholders Agreement pursuant to Section 8.8(c) thereof with respect to any
Overlap Territory (as defined therein) (any such termination being referred to
hereinafter as the "Exchange Event"), the following provisions shall apply:
                    --------------

  (a) Right to Exchange. The Corporation shall have the right, exercisable in
      -----------------
its sole discretion by written notice (the "Exchange Notice") given to the
                                            ---------------
Initial Holders and Section 4.11 Transfers within 60 days after the Exchange
Event, to:

  (i)   require the Initial Holders and each Section 4.11 Transferee to exchange
for an equivalent number of shares of Series B Preferred Stock either (A) all of
the shares of Series A Preferred Stock then owned by the Initial Holders and
each Section 4.11 Transferee or (B) a number of shares of Series A Preferred
Stock then owned by each such holder equal to the product of (x) the number of
shares of Series A Preferred Stock then owned by such holder multiplied by (y) a
fraction, the numerator of which is equal to the number of POPs (as defined in
the Stockholders Agreement) in the Overlap Territory and the denominator of
which is equal to the total number of POPs in the Territory (as defined in the
Stockholders Agreement); and

  (ii)  require the Initial Holders and each Section 4.11 Transferee to
exchange, for a number of shares of Series B Preferred Stock determined in
accordance with paragraph (b) below, either (A) all of the shares of Series D
Preferred Stock, Series F Preferred Stock and Common Stock owned by the Initial
Holder on July 17, 1998 (or shares of Common Stock into which such shares of
Series D Preferred Stock, and Series F Preferred Stock shall have been
converted) and that the Initial Holders or a Section 4.11 Transferee continues
to own on the date of delivery of the Exchange Notice (any such shares of Series
D Preferred Stock, Series F Preferred Stock or Common Stock being referred to
hereinafter collectively as "Original Shares") or (B) a number of Original
                             ---------------
Shares of Series D Preferred Stock, Series F Preferred Stock and Common Stock
equal to the product of (x) the number of Original Shares of Series D Preferred
Stock,

                                      -25-
<PAGE>

Series F Preferred Stock and Common Stock, as the case may be, then owned by
each such holder, multiplied by (y) a fraction, the numerator of which is equal
to the number of POPs in the Overlap Territory and the denominator of which is
equal to the total number of POPs in the Territory; provided, that (x) if the
Corporation exercises its right under clause (i)(A) of this paragraph (a), it
shall be required to exercise its right under clause (ii)(A) of this paragraph
(a), and vice-versa; and if the Corporation exercises its right under clause
(i)(B) of this paragraph (a), it shall be required to exercise its right under
clause (ii)(B) of this paragraph (a), and vice-versa and (y) the provisions of
this Section 4.11(a) shall not apply to any Section 4.11 Transferee which is a
Cash Equity Investor.

(Shares of Series A Preferred Stock, Series D Preferred Stock, Series F
Preferred Stock and Series G Preferred Stock (and shares of Common Stock into
which such shares shall have been converted) and shares of Common Stock subject
to exchange pursuant to this Section 4.11 are hereinafter referred to
collectively as "Exchange Shares.")
                 ---------------

     (b) Number of Shares of Series B Preferred Stock Issuable in Exchange. The
         -----------------------------------------------------------------
number of shares of Series B Preferred Stock issuable in exchange for Original
Shares pursuant to clause (ii) of paragraph (a) above shall be equal to the
quotient of the aggregate purchase price paid by the Initial Holders for the
Original Shares being exchanged, divided by $1,000.

     (c) Fractional Shares. Notwithstanding any other provision of this Restated
         -----------------
Certificate of Incorporation, the Corporation shall not be required to issue
fractions of shares upon exchange of any Exchange Shares or to distribute
certificates which evidence fractional shares. In lieu of fractional shares, the
Corporation may pay therefor, at the time of any exchange of Exchange Shares as
herein provided, an amount in cash equal to such fraction multiplied by the
Market Price of a share of Common Stock on such date.

     (d) Mechanics of Exchange. The Exchange Notice shall specify the date fixed
         ---------------------
for the exchange (the "Exchange Date"), which shall be at least ten but no more
                       -------------
than 60 days following delivery of the Exchange Notice, and the place designated
for exchange of the Exchange Shares pursuant to this Section 4.11. Such notice
will be sent by first class or registered mail, postage prepaid, to the Initial
Holders and each Section 4.11 Transferee at such holder's address last shown on
the records of the transfer agent for the Exchange Shares (or the records of the
Corporation if it serves as its own transfer agent). On or before the Exchange
Date, the Initial Holders and each Section 4.11 Transferee shall surrender its
certificate or certificates for all such shares to the Corporation at the place
designated in such notice. If required by the Corporation, certificates
surrendered for exchange shall be endorsed or accompanied by a written
instrument or instruments of transfer, in form satisfactory to the Corporation,
duly executed by the Initial Holders and each Section 4.11 Transferee or its
attorney duly authorized in writing.

     (e) Termination of Rights. On and after the Exchange Date (whether or not
         ---------------------
the applicable certificates have theretofore been surrendered), all rights with
respect to the Exchange Shares, including the rights, if any, to receive notices
and to vote, will

                                      -26-
<PAGE>

terminate, except only the rights of the Initial Holders and Section 4.11
Transferees to receive certificates for the number of shares of Series B
Preferred Stock into which such Exchange Shares have been exchanged, upon
surrender of its certificate or certificates therefor, and payment of any
declared but unpaid dividends thereon (which shall accrue and be payable at the
times and on the other terms applicable to such dividends when declared) and
payment of any deferred dividends in respect of Series A Preferred Stock which
shall be payable as set forth in Section 4.3(b)(iii). Within ten Business Days
after the Exchange Date, the Corporation shall issue and deliver to the Initial
Holders and each Section 4.11 Transferee, or on its written order to its
nominees, a certificate or certificates for the number of whole shares of Series
B Preferred Stock issuable upon such exchange in accordance with the provisions
hereof, together with cash in lieu of fractional shares calculated in accordance
with paragraph (c) of this Section 4.11.

     (f) Reservation of Shares. The Corporation shall at all times reserve and
         ---------------------
keep available for issuance upon the exchange of Exchange Shares the maximum
number of its authorized but unissued shares of Series B Preferred Stock as is
reasonably anticipated to be sufficient to permit the exchange of all
outstanding Exchange Shares, and shall take all action required to increase the
authorized number of shares of Series B Preferred Stock if at any time there
shall be insufficient authorized but unissued shares of Series B Preferred Stock
to permit such reservation or to permit the exchange of all outstanding Exchange
Shares.

     (g) Adjustments for Dividends.  Upon any exchange of Exchange Shares, no
         -------------------------
adjustment to the rate of conversion shall be made for accrued and unpaid
dividends (whether or not declared) on the Exchange Shares, as the case may be,
surrendered for exchange or on the Series B Preferred Stock delivered upon
exchange.

     (h) No Exchange Charge or Tax. The issuance and delivery of certificates
         -------------------------

     7.4 Continuing Rights.  The rights to indemnification and reimbursement or
         -----------------
advancement of expenses provided by, or granted pursuant to, this Article VII
shall continue as to a person who has ceased to be a Director or officer (or
other person indemnified hereunder), shall inure to the benefit of the
executors, administrators, legatees and distributees of such person, and in
either case, shall inure whether or not the claim asserted is based on matters
which antedate the adoption of this Article VII.

     7.5 Insurance.  The Corporation shall have power to purchase and maintain
         ---------
insurance on behalf of any person who is or was a Director, officer, employee or
agent of the Corporation, or is or was serving at the request of the
Corporation, as a director, officer, employee or agent of an Other Entity,
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the Corporation would have the power to indemnify such person against such
liability under the provisions of this Article VII, the Bylaws or under Section
145 of the GCL or any other provision of law.

     7.6 Contract Rights; No Repeal. The provisions of this Article VII shall be
         --------------------------
a contract between the Corporation, on the one hand, and each Director and
officer who serves in such capacity at any time while this Article VII is in
effect and any other person indemnified hereunder, on the other hand, pursuant
to which the Corporation and each such Director, officer, or other person intend
to be legally bound. No repeal or modification of this Article VII shall affect
any rights or obligations with respect to any state of facts then or, heretofore
or thereafter brought or threatened based in whole or in part upon any such
state of facts.

     7.7 Enforceability; Burden of Proof.  The rights to indemnification and
         -------------------------------
reimbursement or advancement of expenses provided by, or granted pursuant to,
this Article VII shall be enforceable by any person entitled to such
indemnification or reimbursement or advancement of expenses in any court of
competent jurisdiction.  The burden of proving that such indemnification or
reimbursement or advancement of expenses is not appropriate shall be on the

                                      -36-
<PAGE>

Corporation.  Neither the failure of the Corporation (including its Board of
Directors, its independent legal counsel and its stockholders) to have made a
determination prior to the commencement of such action that such indemnification
or reimbursement or advancement of expenses is proper in the circumstances nor
an actual determination by the Corporation (including its Board of Directors,
its independent legal counsel and its stockholders) that such person is not
entitled to such indemnification or reimbursement or advancement of expenses
shall constitute a defense to the action or create a presumption that such
person is not so entitled.  Such a person shall also be indemnified for any
expenses incurred in connection with successfully establishing his or her right
to such indemnification or reimbursement or advancement of expenses, in whole or
in part, in any such Proceeding.

     7.8 Service at the Request of the Corporation. Any Director or officer of
         -----------------------------------------
the Corporation serving in any capacity in (a) another corporation of which a
majority of the shares entitled to vote in the election of its directors is
held, directly or indirectly, by the Corporation or (b) any employee benefit
plan of the Corporation or any corporation referred to in clause (a) shall be
deemed to be doing so at the request of the Corporation.

     7.9 Right to Be Covered by Applicable Law. Any person entitled to be
         -------------------------------------
indemnified or to reimbursement or advancement of expenses as a matter of right
pursuant to this Article VII may elect to have the right to indemnification or
reimbursement or advancement of expenses interpreted on the basis of the
applicable law in effect at the time of the occurrence of the event or events
giving rise to the applicable Proceeding, to the extent permitted by law, or on
the basis of the applicable law in effect at the time such indemnification or
reimbursement or advancement of expenses is sought. Such election shall be made,
by a notice in writing to the Corporation, at the time indemnification or
reimbursement or advancement of expenses is sought; provided, however, that if
no such notice is given, the right to indemnification or reimbursement or
advancement of expenses shall be determined by the law in effect at the time
indemnification or reimbursement or advancement of expenses is sought.

                                 ARTICLE VIII

                                      -37-
<PAGE>

     No Director of the Corporation shall be liable to the Corporation or any of
its stockholders for monetary damages for breach of fiduciary duty as a
Director, provided that this provision does not eliminate the liability of the
Director (i) for any breach of the Director's duty of loyalty to the Corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the GCL or (iv) for any transaction from which the Director
derived an improper personal benefit.  For purposes of the prior sentence, the
term "damages" shall, to the extent permitted by law, include without
limitation, any judgment, fine, amount paid in settlement, penalty, punitive
damages, excise or other tax assessed with respect to an employee benefit plan,
or expense of any nature (including, without limitation, counsel fees and
disbursements).  Each person who serves as a Director of the Corporation while
this Article VIII is in effect shall be deemed to be doing so in reliance on the
provisions of this Article VIII, and neither the amendment or repeal of this
Article VIII, nor the adoption of any provision of this Restated Certificate of
Incorporation inconsistent with this Article VIII, shall apply to or have any
effect on the liability or alleged liability of any Director of the Corporation
for, arising out of, based upon, or in connection with any acts or omissions of
such Director occurring prior to such amendment, repeal, or adoption of an
inconsistent provision.  The provisions of this Article VIII are cumulative and
shall be in addition to and independent of any and all other limitations on or
eliminations of the liabilities of Directors of the Corporation, as such,
whether such limitations or eliminations arise under or are created by any law,
rule, regulation, bylaw, agreement, vote of stockholders or disinterested
Directors, or otherwise.


                                  ARTICLE IX

     9.1 Number, Terms and Election of Directors.
         ---------------------------------------

     (a) Subject to the rights, if any, of the holders of any class or series of
Preferred Stock to elect additional directors under specified circumstances, the
number of directors of the Corporation shall be fixed and may be increased or
decreased from time to time by the Board of Directors, but in no case shall the
number be less than one nor more than fifteen.

     (b) Upon the closing of an offer and sale of the Class A Common Stock of
the Corporation to the public (a "Public Offering") pursuant to an effective
Registration Statement under the Securities Act of 1933, as amended (the "1933
Act"), in which (i) the aggregate gross proceeds received by the Corporation in
connection with such Registration Statement(s) equals or exceeds $20 million,
and (ii) the Class A Common Stock shall have been listed for trading on the New
York Stock Exchange or the American Stock Exchange or authorized for trading on
NASDAQ, including without limitation its National Market System, the then
current directors and any new directors taking office upon such closing shall be
divided into three classes, as nearly equal in number as possible, by the
affirmative vote (which vote may be taken prior to such closing) of a majority
of the directors then holding office. One class of directors shall be appointed
to the Board of Directors for a term expiring at the first annual meeting of
stockholders to be held after the closing date of the Public Offering, another
class of directors shall be appointed to the Board of Directors for a term
expiring at the second annual meeting of stockholders to be held after the
closing date of the Public Offering, and another class of

                                      -38-
<PAGE>

directors shall be appointed to the Board of Directors for a term expiring the
third annual meeting of stockholders to be held after the closing date of the
Public Offering, with members of each class to hold office until their
successors are elected and qualified. At each succeeding annual meeting of the
stockholders of the Corporation, the successors of the class of directors whose
term expires at that meeting shall be elected by plurality vote of all votes
cast at such meeting to hold office for a term expiring at the annual meeting of
stockholders held in the third year following their year of election.


     9.2 Newly Created Directorships and Vacancies. Subject to the rights, if
         -----------------------------------------
any, of the holders of any and all series of Preferred Stock to elect additional
directors pursuant to the terms and conditions of such Preferred Stock, newly
created directorships resulting from any increase in the number of directors and
any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other cause shall be filled solely by the
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the board of directors, or by a sole remaining
director. Any director elected in accordance with the preceding sentence shall
hold office for the remainder of the full term of the class of directors in
which the new directorship was created or the vacancy occurred and until such
director's successor shall have been elected and qualified. No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of an incumbent director.

     9.3 Removal.  Subject to the rights, if any, of the holders of any and all
         -------
series of Preferred Stock to elect additional directors pursuant to the terms
and conditions of such Preferred Stock, any director may be removed from office
by the stockholders only for cause and only in the following manner. At any
annual meeting or special meeting of the stockholders of the Corporation, the
notice of which shall state that the removal of a director or directors is among
the purposes of the meeting, the affirmative vote of the holders of at least a
majority of the outstanding shares of capital stock of the Corporation entitled
to vote generally in the election of the directors, voting together as a single
class, may remove such director or directors for cause.

     9.4 Additional Rights of Certain Stockholders Regarding Directors.
         -------------------------------------------------------------
Notwithstanding anything to the contrary contained in this Article IX, so long
as a Stockholder (as such term is defined in the Stockholders' Agreement) or
group of Stockholders has the right to nominate one or more of the directors of
the Corporation pursuant to the terms of the Stockholders' Agreement or this
Fifth Amended and Restated Certificate of Incorporation (including, without
limitation, the right of the Initial Holders to nominate a director pursuant to
Section 4.3(d)(iii) hereof), then, with respect to any directors so nominated by
such Stockholder or group of Stockholders, such Stockholder or group of
Stockholders, as the case may be, shall have the right to cause the Corporation
to remove any director so nominated by such Stockholder or group of
stockholders, as the case may be, with or without cause, and any vacancy caused
by the removal of such director or otherwise during the term of such director
(whether or not such director resigns, is removed from the Board of Directors
with or without cause or ceases to be a director by reason of death, disability
or for any other reason) shall be filled in accordance with the terms of the

                                      -39-
<PAGE>

Stockholders' Agreement or this Fifth Amended and Restated Certificate of
Incorporation, as the case may be.

          IN WITNESS WHEREOF, the undersigned officer of the Corporation has
executed this Fifth Amended and Restated Certificate of Incorporation this ___
day of ___________, 1999.

                                  ARTICLE 1.

                                 STOCKHOLDERS

     1.1  Annual Meeting.  The annual meeting of the stockholders of the
          --------------
Corporation for the election of directors and for the transaction of such other
business as may properly come before such meeting shall be held at such place,
either within or without the State of Delaware, at 9:00 A.M.  on the second
Wednesday of each April of each year (or, if such day is a legal holiday, then
on the next succeeding business day), or at such other date and hour, as may be
fixed from time to time by resolution of the Board of Directors and set forth in
the notice or waiver of notice of the meeting.

          At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before an annual meeting.  To be
properly brought before an annual meeting, business must be (i) specified in the
notice of the meeting (or any supplement thereto) given by or at the direction
of the Board of Directors, (ii) otherwise properly brought before the meeting by
or at the direction of the Board of Directors or (iii) otherwise properly
brought before the meeting by a stockholder of the Corporation who was
stockholder of record at the time of giving of notice provided for in this
Section, who is entitled to vote at the meeting and who complied with the notice
procedures set forth in this Section.  For business to be properly brought
before an annual meeting by a stockholder, the stockholder must have given
timely notice thereof in writing to the Secretary of the Corporation at the
principal executive office of the corporation.  To be timely, a stockholder's
notice shall be delivered not less than 90 days prior to the first anniversary
of the preceding year's meeting;  provided, however, that in the event that the
date of the annual meeting is advanced by more than 30 days or delayed by more
than 60 days from such anniversary date, notice by the stockholder, to be
timely, must be so delivered not later than the 10th day following the day on
which public announcement (as defined herein) of the date of such meeting is
first made.

          Such stockholder's notice shall set forth as to each matter the
stockholder proposes to bring before the annual meeting (i) a brief description
of the business desired to be brought before the meeting and the reasons for
conducting such business at the meeting and any material interest in such
business of such stockholder and the beneficial owner, if any, on whose behalf
the proposal is made; and (ii) as to the stockholder giving the notice and the
beneficial owner, if any, on whose behalf the proposal is made (A) the name and
address of such stockholder, as they appear on the Corporation's books, and the
name and address of such beneficial owner and (B) the class and number of shares
of the
<PAGE>

Corporation which are owned beneficially and of record by such stockholder and
such beneficial owner; and (iii) in the event that such business includes a
proposal to amend either the Certificate of Incorporation or the Bylaws of the
Corporation, the language of the proposed amendment. Notwithstanding anything in
these Bylaws to the contrary, no business shall be conducted at any annual
meeting except in accordance with the preceding paragraph, and the Chairman of
the Board or other person presiding at an annual meeting of stockholders, may
refuse to permit any business to be brought before an annual meeting without
compliance with the foregoing procedures. "Public Announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Sections 13,
14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). In addition to the provisions of this paragraph, a stockholder shall also
comply with all applicable requirements of the Exchange Act and the rules and
regulations thereunder with respect to the matters set forth herein. Nothing in
these Bylaws shall be deemed to affect any rights of the Stockholders to request
inclusion of proposals in the Corporation's proxy statement pursuant to Rule
14a-8 under the Exchange Act.

     1.2 Special Meetings. Special meetings of the stockholders may be called at
         ----------------
any time by the Chairman of the Board (or, in the event of his absence or
disability, by the President). A special meeting shall be called by the Chairman
of the Board (or, in the event of his absence or disability, by the President),
or by the Secretary, immediately upon receipt of a written request therefor by
stockholders holding in the aggregate not less than 35% of the outstanding
shares of the Corporation at the time entitled to vote at any meeting of the
stockholders or by a request of a majority of the Board of Directors. If such
officers shall fail to call such meeting within 20 days after receipt of such
request, any stockholder or member of the Board of Directors executing such
request may call such meeting.

     Any such special meeting of the stockholders shall be held at such place,
within or without the State of Delaware, as shall be specified in the notice or
waiver of notice thereof.

     1.3  Notice of Meetings; Waiver. The Secretary or any Assistant Secretary
          --------------------------
shall cause written notice of the place, date and hour of each meeting of the
stockholders, and, in the case of a special meeting, the purpose or purposes for
which such meeting is called, to be given personally or by mail, not less than
ten nor more than 60 days before the date of the meeting, to each stockholder of
record entitled to vote at such meeting. If such notice is mailed, it shall be
deemed to have been given to a stockholder when deposited in the United States
mail, postage prepaid, directed to the stockholder at his address as it appears
on the record of stockholders of the Corporation, or, if he shall have filed
with the Secretary a written request that notices to him be mailed to some other
address, then directed to him at such other address. Such further notice shall
be given as may be required by law.

                                       2
<PAGE>

         Whenever notice is required to be given to stockholders hereunder, a
written waiver, signed by a stockholder, whether before or after the time stated
therein, shall be deemed equivalent to notice.  Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the
stockholders need be specified in a written waiver of notice.  The attendance of
any stockholder at a meeting of stockholders shall constitute a waiver of notice
of such meeting, except when the stockholder attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business on the ground that the meeting is not lawfully called or convened.

    1.4  Quorum; Voting.  Except as otherwise required by law or by the
         --------------
Corporation's Certificate of Incorporation, as then amended and in effect (the
"Certificate of Incorporation"), at any meeting of the stockholders, a majority
of all shares issued and outstanding and entitled to vote upon a question to be
considered at the meeting shall constitute a quorum when represented at such
meeting by the holders thereof in person or by their duly constituted and
authorized attorney or attorneys, but holders of a lesser interest may adjourn
any meeting from time to time, and the meeting may be held as adjourned without
further notice.  When a quorum is present at any meeting, a majority of the
stock so represented thereat and voting on any question brought before such
meeting shall be determinative, except where a larger vote is required by law,
by the Certificate of Incorporation or by these by-laws, and except that the
vote required for the election of directors shall be as set forth in the
Certificate of Incorporation.

         Except as set forth in the Certificate of Incorporation, if, pursuant
to Section 5.5 of these Bylaws, a record date has been fixed, every holder of
record of shares entitled to vote at a meeting of stockholders shall be entitled
to one vote for each share outstanding in his name on the books of the
Corporation at the close of business on such record date. If no record date has
been fixed, then every holder of record of shares entitled to vote at a meeting
of stockholders shall be entitled to one vote for each share of stock standing
in his name on the books of the Corporation at the close of business on the day
next preceding the day on which notice of the meeting is given, or, if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held.

    1.5  Voting by Ballot. No vote of the stockholders need be taken by written
         ----------------
ballot or conducted by inspectors of election, unless otherwise required by law.
Any vote which need not be taken by ballot may be conducted in any manner
approved by the meeting.

    1.6  Adjournment.  If a quorum is not present at any meeting of the
         -----------
stockholders, the stockholders present in person or by proxy shall have the
power to adjourn any such meeting from time to time until a quorum is present.
Notice of any adjourned meeting of the stockholders of the Corporation need not
be given if the place, date and hour thereof are announced at the meeting at

Arlington, Virginia 22201

Ladies and Gentlemen:

         We refer to the Registration Statement (the "Registration Statement")
on Form S-1 (File No. 333-89393), filed by TeleCorp PCS, Inc., a Delaware
corporation (the "Company"), with the Securities and Exchange Commission (the
"Commission"), for the purpose of registering under the Securities Act of 1933,
as amended (the "Securities Act"), shares of the Company's Class A Common Stock,
par value $.01 per share (the "Class A Common Stock"), to be offered to the
public pursuant to an Underwriting Agreement (the "Underwriting Agreement")
among the Company and Salomon Smith Barney Inc., Lehman Brothers Inc., Deutsche
Bank Securities Inc., Merrill Lynch, Pierce Fenner & Smith Incorporated, as
representatives of the underwriters.

         In connection with the foregoing registration, we have acted as counsel
for the Company and have examined originals or copies, certified or otherwise
identified to our satisfaction, of all such records of the Company and all such
agreements, certificates of public officials, certificates of officers or
representatives of the Company and others, and such other documents,
certificates and corporate or other records as we have deemed necessary or
appropriate as a basis for the opinion set forth herein. In our examination we
have assumed the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified
or photostatic copies and the authenticity of the originals of such latter
documents.

         We are members of the Bar of The Commonwealth of Massachusetts and do
not purport to be experts on, or generally familiar with, or certified to
express legal conclusions based upon, the laws of any other jurisdiction, other
than the corporate laws of the State of Delaware and the laws of the United
States to the extent applicable hereto. Accordingly, as to matters of law set
forth below, our opinion is limited to matters of law under the laws of the
District of Columbia, the laws of the United States to the extent applicable
hereto and the corporate laws of the State of Delaware, and we express no
opinion as to the laws of any states or jurisdictions other than as specified
above.
<PAGE>

         Based upon the foregoing and subject to the other qualifications stated
herein, we are of the opinion that the shares of Class A Common Stock being
registered by the Company pursuant to the Registration Statement have been duly
authorized and, when issued and delivered in accordance with the terms of the
Underwriting Agreement, will be legally issued, fully paid and non-assessable.

         We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and any abbreviated registration statements relating
thereto that may be filed to register additional securities identical to those
covered by the Registration Statement (including a registration statement filed
pursuant to Rule 462(b) under the Securities Act), and to the reference to this
firm under the caption "Legal Matters" contained in the prospectus filed as a
part thereof. In giving such consent, we do not thereby admit that we are in the
category of persons whose consent is required under Section 7 of the Securities
Act.


                                                   Very truly yours,

                                                   /s/ McDermott, Will & Emery

end adjustments and footnote disclosure.

          (b) The forecast of the Company and its Subsidiaries contained in the

          6.6  Compliance with Other Instruments, etc.  Neither the Company
               ---------------------------------------

of incorporation or by-laws.  Neither the Company nor any Subsidiary is, and,
after giving effect to the Financing Transactions, neither the Company nor any
Subsidiary will be, in material violation of any term of any agreement or
instrument to which it is a party or by which it or any of its properties or
assets is bound, or any term of any applicable law, ordinance, rule or
regulation of any Governmental Authority or any term of any applicable order,
judgment or decree of any court, arbitrator or Governmental Authority, the
consequences of any which violation (or all such violations in the aggregate)
would reasonably be expected to have a Material Adverse Effect; and the
execution, delivery and performance of this Agreement and the Notes will not
result in any material violation of or be in material conflict with or

section 6.8 of the Disclosure Schedule.  Except in each case as specified
therein, the Company does not have outstanding securities convertible into or
exchangeable for any shares of its Capital Stock, nor will it have outstanding

Capital Stock or any securities convertible into or exchangeable for any shares
of its Capital Stock.

and its Subsidiaries to be outstanding, or for which the Company or any
Subsidiary will have commitments, on the Effective Date and the Initial Series B
Closing Date, in each case, after giving effect to the Financing Transactions.

                --------------------------
Subsidiaries has good and marketable title to all its material owned properties

other than the Liens in favor of the Administrative Agent for the benefit of the
Lenders and other Liens permitted under the Credit Agreement including any Liens
as to which the Lenders shall have granted their consent or waived any objection
and other Liens which could not reasonably be expected to have a Material
Adverse Effect.  On each Closing Date and after giving effect to the Financing

undisturbed possession under all leases necessary for the operation of its
business, and all such leases will be valid and subsisting and will be in full
force and effect except where such failure could not reasonably be expected to

          6.14  Federal Reserve Regulations.  The Company will not use any of
                ---------------------------
the proceeds of the sale of the Notes for the purpose, whether immediate,
incidental or ultimate, of buying a "margin stock" or of maintaining, reducing
or retiring any indebtedness originally incurred to purchase a stock that is
currently a "margin stock", or for any other purpose which might constitute this
transaction a "purpose credit", in each case, within the meaning of Regulation U
of such Board (12 C.F.R. 221, as amended), or otherwise take or permit to be
taken any action which would involve a violation of such Regulation U or of
Regulation T (12 C.F.R. 220, as amended) or Regulation X (12 C.F.R. 224, as
amended) or any other regulation of such Board.  No Debt of the Company or any
Subsidiary being reduced or retired out of the proceeds of the sale of the Notes
was incurred for the purpose of purchasing or carrying any such "margin stock"
and neither the Company nor any Subsidiary owns or has any present intention of
acquiring any such "margin stock".

          6.15  Status Under Certain Federal Statutes.  Neither the Company
                -------------------------------------
nor any Subsidiary is, and after giving effect to the Financing Transactions
none of them will be, (a) an "investment company", or a company "controlled" by
an "investment company", within the meaning of the Investment Company Act of
1940, as amended; (b) a "holding company" or a "subsidiary company" of a
"holding company", or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company", as such terms are defined in the Public Utility
Holding Company Act of 1935, as amended; (c) a "public utility", as such term is
defined in the Federal Power Act, as amended; or (d) a "rail carrier or a person
controlled by or affiliated with a rail carrier", within the meaning of Title
49, U.S.C., or a "carrier" to which 49 U.S.C.  11301(b)(1) is applicable.
Neither the Company nor any Subsidiary is subject to regulation under any
Federal or state statute, regulation, decree or order which limits its ability
to incur Debt or conditions such ability upon any act, approval or consent of
any Governmental Authority.

          6.16  Compliance with ERISA.  Neither the acquisition of the Notes
                ---------------------
by you nor the consummation of any of the other transactions contemplated by
this Agreement is or will constitute a "prohibited transaction" within the
meaning of Section 4975 of the Code, or Section 406 of ERISA.

          6.17  Offer of Securities.  The sale of the Notes in accordance with
                -------------------
the terms of this Agreement (a) is exempt from the registration requirements of
the Securities Act and applicable state securities or blue sky laws and (b) does
not require the qualification of an indenture under the Indenture Act.  Neither
the Company nor any financial advisor of the

                                      -13-
<PAGE>

Company has directly or indirectly offered the securities to be purchased by you
pursuant to this Agreement or any part thereof or any similar securities for
sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with any Person other than you.
Neither the Company nor anyone acting on its behalf has taken or will take any
action which would subject the issuance and sale of the Notes to the
registration and prospectus delivery provisions of the Securities Act.

          6.18  Use of Proceeds.  The Company will apply the proceeds of the
                ---------------
sale of the Notes solely to develop PCS Systems in the Designated Areas and the
SLE Expansion Area.

          6.19  Solvency of the Company.  As of each Closing Date, (a) the
                -----------------------
aggregate value of all the assets of the Company and its Subsidiaries taken as a
whole, at a fair valuation, will exceed the total liabilities of such Person
(including contingent, subordinated, unmatured and unliquidated liabilities);
(b) each of the Company and its Subsidiaries will be able to pay its debts as
they mature; and (c) neither  the Company nor any Subsidiary will have
unreasonably small capital for the business in which it is proposed to be
engaged.  For purposes of this section 6.19, the "fair valuation" of any asset
will be that amount which may be realized within a reasonable time, either
through collection or sale of such asset at fair market value, defining the
latter as the amount which could be obtained for the property in question within
such period by a willing seller from a willing buyer, each having reasonable
knowledge of the relevant facts, neither being under any compulsion to act, with
equity to both.  Neither the Company nor any Subsidiary has any intent to
hinder, delay or defraud any entity to which it is, or will become, on or after
the Initial Series A Closing Date, indebted or to incur debts that would be
beyond its ability to pay as they mature.

          6.20  Certain Fees.  Except for the fees referred to in section 3.4
                ------------
and as disclosed on section 6.20 of the Disclosure Schedule, no broker's or
finder's fee or commission has been paid or will be payable by the Company with
respect to the offer, issue and sale of the Notes or with respect to the
Financing Transactions and the Company hereby indemnifies you against, and will
hold you harmless from, any claim, demand or liability asserted against you for
broker's or finder's fees alleged to have been incurred by the Company or any
other Person (other than you or your Affiliates) in connection with any such
offer, issue and sale or the Financing Transactions or any of the other
transactions contemplated by this Agreement.

          6.21  Regulatory Compliance.  (a) The Company and its Subsidiaries
                ---------------------
are in compliance with the Communications Act and the Telecommunications Act,
except to the extent that the failure to be in compliance could not reasonably
be expected to have a Material Adverse Effect.

          (b) None of the chief executive officer, chief operating officer,
chief financial officer, general counsel or any other officer or employee of the
Company specifically charged with having knowledge of or monitoring FCC matters
has knowledge of any investigation, notice of apparent liability, violation,
forfeiture or other order or complaint issued by or before the FCC,

                                      -14-
<PAGE>

or of any other proceedings of or before the FCC, which could reasonably be
expected to have a Material Adverse Effect.

          (c) Each of the Company and its Subsidiaries holds all Licenses
necessary for the operation of its business as currently conducted except where
the failure to hold such Licenses could not reasonably be expected to have a
Material Adverse Effect.  No event has occurred which (i) results in, or after
notice or lapse of time or both would result in, revocation, suspension, adverse
modification, non-renewal, impairment, restriction or termination of, or order
of forfeiture with respect to, any such License in any respect that could
reasonably be expected to have a Material Adverse Effect, or (ii) affects or
could reasonably be expected in the future to affect any of the rights of the
Borrower or its Subsidiaries under any License in any respect that could
reasonably be expected to have a Material Adverse Effect.

          (d) The Company and its Subsidiaries have duly filed in a timely
manner all material filings, reports, applications, documents, instruments and
information required to be filed by it under the Communications Act, the
Telecommunications Act and under any other applicable federal, state and local
laws, and all such filings were when made true, correct and complete in all
material respects, except to the extent that the failure of any of the foregoing
to be true and correct could not reasonably be expected to have a Material
Adverse Effect.

          (e) TeleCorp Holdings currently qualifies, and at all times since it
has held any Licenses from the FCC has qualified and will qualify, as a "very
small business," as defined in 47 C.F.R. 101.112(b), and neither the Company nor
TeleCorp Holdings has committed or has any present intention to take any action
that would result in TeleCorp Holdings not being qualified as a "very small
business" other than by reason of its annual gross revenues.  As a result of the
closing of the transactions under Article II and Article III of the Securities
Purchase Agreement the Company owns 100% of the issued and outstanding Capital
Stock of TeleCorp Holdings.

          6.22  Disclosure.  Neither this Agreement nor any other document,
                ----------
certificate or instrument delivered to you by or on behalf of the Company in
connection with the transactions contemplated by this Agreement taken as a whole
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements contained herein and therein, in
light of the circumstances under which they were made, not misleading (it being
understood that, except as set forth in section 6.4, no representation or
warranty is made with respect to any projections or other prospective financial
information).  There is no fact known to the Company (other than matters of a
general economic or political nature which do not affect the Company uniquely)
which has resulted in, or could reasonably be expected to result in, a Material
Adverse Effect, which has not been set forth in this Agreement or in the other
documents, certificates and instruments delivered to you by or on behalf of the
Company in connection with the transactions contemplated hereby and thereby.

favorable to the Company or such Restricted Subsidiary, as the case may be, than
those which might be obtained, in the good faith judgment of the Company, in an
arm's length transaction at the time from Persons which are not Affiliates and,
in the case of any transaction between the Company and any Management
Stockholder(or any Affiliate of any Management Stockholder) shall have been
approved by a majority of the directors (excluding any directors who are either
Management Stockholders or who are selected by the Management Stockholders and
are not subject to approval by any of the other holders of the Capital Stock of
the Company); provided that the foregoing restrictions shall not apply to the
transactions contemplated under the Transaction Documents or any transaction
between the Company and any Wholly-Owned Subsidiary or between one Wholly-Owned
Subsidiary and another Wholly-Owned Subsidiary.

          11.8  Corporate Existence, etc.; Business.  The Company shall at all
                -----------------------------------
times preserve and keep in full force and effect its corporate existence,
rights, qualifications and franchises (including, without limitation, all
Licenses) deemed material to its business and those of each of its Subsidiaries
(including, in the case of TeleCorp Holdings,  its qualification as a "very
small business" as defined as 47 C.F.R. 101.112(b) other than by reason of its
annual gross revenues), except as otherwise specifically permitted by section
11.5 and except to the extent that failure to do so could not reasonably be
expected to have a Material Adverse Effect.

          11.9  Limitation on Designation of Unrestricted Subsidiaries.  The
                ------------------------------------------------------
Company may designate any Subsidiary of the Company (other than the Real
Property Subsidiary and the Equipment Subsidiary) as an "Unrestricted
Subsidiary" under this Agreement (a "Designation") only if:

          (i) no Default or Event of Default shall have occurred and be
     continuing at the time of or after giving effect to such Designation; and

          (ii) the Company would be permitted under the Indenture to make an
     Investment at the time of Designation (assuming the effectiveness of such
     Designation) in an amount (the "Designation Amount") equal to the Fair
     Value of the aggregate amount of its Investments in such Subsidiary on such
     date;

          (iii)  the Company would be permitted to incur $1.00 of additional
     Debt pursuant to the terms of any supplemental indenture to the Indenture
     at the time of Designation (assuming the effectiveness of such
     Designation); and

          (iv) such Subsidiary does not and will not own or hold any FCC
     licenses (other than FCC licenses in respect of cellular communications
     covering an area that has been built out and is, on the date of
     Designation, actively and continuously in operation).

                                      -27-
<PAGE>

          In the event of any such Designation, the Company shall be deemed to
have made an Investment constituting a Restricted Payment in an amount equal to
the Designation Amount.

          The Company shall not, and shall not permit any Restricted Subsidiary,
at any time (x) to provide direct or indirect credit support for or a guarantee
of any Debt of any Unrestricted Subsidiary (including of any undertaking,
agreement or instrument evidencing such Debt), (y) be directly or indirectly
liable for any Debt of any Unrestricted Subsidiary or (z) be directly or
indirectly liable for any Debt which provides that the holder thereof may (upon
notice, lapse of time or both) declare a default thereon or cause the payment
thereof to be accelerated or payable prior to its final scheduled maturity upon
the occurrence of a default with respect to any Debt of any Unrestricted
Subsidiary (including any right to take enforcement action against such
Unrestricted Subsidiary), except, in the case of clause (x) or (y), to the
extent permitted under the terms of any covenant with respect to Restricted
Payments contained in a this Agreement.  The Company may revoke any Designation
of a Subsidiary as an Unrestricted Subsidiary (a "Revocation"), whereupon such
Subsidiary shall then constitute a Restricted Subsidiary, if:

          (a)  no Default or Event of Default shall have occurred and be
     continuing at the time of and after giving effect to such Revocation; and

          (b)  all Liens and Debt of such Unrestricted Subsidiary outstanding
     immediately following such Revocation would, if incurred at such time, have
     been permitted to be incurred for all purposes of this Agreement.

          All Designations and Revocations must be evidenced by resolutions of
the Board delivered to you certifying compliance with the foregoing provisions.

          11.10  Limitation on Activities of the Company and the Restricted
                 ----------------------------------------------------------
Subsidiaries.  The Company shall not, and shall not permit any Restricted

               -------------------------------
conditions or events ("Events of Default") shall occur and be continuing:

premium, if any, on or any other amount (other than interest not paid in
connection with a prepayment or redemption) with respect to any Note when the
same becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration or otherwise; or

          (b) if the Company shall default in the payment of any cash interest

and payable; or

                                      -28-
<PAGE>

          (c) if the Company shall default in the performance of section 11.5;
or

          (d) if the Company shall default in the performance of or compliance
with any other term contained in this Agreement and such default shall not have
been remedied within 30 days after such failure shall first have become known to
any Responsible Officer of  the Company or written notice thereof shall have
been received by the Company from any holder of any Note; or

          (e) if any representation or warranty made in writing by or on behalf
of the Company in this Agreement or in any instrument furnished in compliance
with this Agreement shall prove to have been false or incorrect in any material
respect on the date as of which made; or

          (f) if the Company or any Subsidiary shall default (as principal or
guarantor or other surety) in the payment of any principal of or premium or

outstanding in the aggregate in a principal amount of at least $15,000,000), or
if any event shall occur or condition shall exist in respect of any such Senior
Debt or under any evidence of any such Senior Debt or of any mortgage, indenture
or other agreement relating thereto, the effect of which default in payment
event or condition is to cause the acceleration of the payment of such Senior
Debt, or to require the Company or Subsidiary to repurchase such Senior Debt,
before its stated maturity or before its regularly scheduled dates of payment;
provided that in the event such default in payment or such event or condition is
- --------
waived and any acceleration rescinded prior to the acceleration of the Notes or
the commencement of any exercise of remedies under section 13 and in any event
within 30 days following such occurrence by each affected holder of such Senior
Debt and by each Person that acquired a remedy as a result of such default in
payment or such event or condition, then such default in payment or such event
or condition shall be deemed waived hereunder; or

          (g) if a final judgment or judgments shall be rendered against the
Company or any Subsidiary for the payment of money in excess of $15,000,000 in
the aggregate (excluding any such judgment covered by insurance not disputed by
the carrier thereof) and any one of such judgments shall not be discharged or
execution thereon stayed or bonded pending appeal within 90 days after entry
thereof or, in the event of such a stay, such judgment shall not be discharged
or satisfied within 90 days after such stay expires; or

          (h) if the Company or any Material Subsidiary shall (i) be generally
not paying its debts as they become due, (ii) file, or consent by answer or
otherwise to the filing against it of, a petition for relief or reorganization
or arrangement or any other petition in bankruptcy, for liquidation or to take

the foregoing; or

                                      -29-

Subsidiary, a custodian, receiver, trustee or other officer with similar powers
with respect to it or with respect to any substantial part of its property, or
if an order for relief shall be entered in any case or proceeding for
liquidation or reorganization or otherwise to take advantage of any bankruptcy
or insolvency law of any jurisdiction, or ordering the dissolution, winding-up
or liquidation of the Company or any Material Subsidiary, or if any petition for
any such relief shall be filed against the Company or any Material Subsidiary
and such petition shall not be dismissed within 60 days; or

          (j) the Company shall be in default of or shall breach any of its
obligations under the Procurement Contract and as a result thereof such
Procurement Contract shall have terminated; provided that no Event of Default
                                            --------
shall exist under this clause (j) if none of the Notes are then held by the
Vendor or, if held by the Vendor, participations have been granted in such Notes
(other than participations to Persons who are Affiliates), then (i) (A)  upon
the occurrence of any Event of Default described in paragraphs (h) and (i) of
this section 12, the Commitments shall automatically terminate and (B) with
respect to any other Event of Default, the Required Holders of the Notes
(subject to section 17) may by notice to the Company declare the Commitments
terminated forthwith whereupon the Commitments shall be terminated, and (ii) (A)
upon the occurrence of any Event of Default described in paragraphs (h) and (i)
of this section 12, the unpaid principal amount of and accrued interest on the
Notes shall automatically be due and payable or (B) with respect to any other
Event of Default (x) if such event is an Event of Default described in
paragraphs (a), (b), (f) or (j), of this section 12 the Required Holders of
Notes at such time outstanding (subject to section 17) may at any time (unless
all defaults shall have been remedied) at its or their option, by written notice
or notices to the Company, declare the Notes to be due and payable; or (y) if
                                                                        -
such event is an Event of Default described in any other paragraph of this
section 12 and such event occurs before the Credit Agreement shall have been
executed and delivered and shall be in full force and effect, the Required
Holders of the Notes (subject to section 17) may declare the Notes due and
payable; whereupon, with reference to any such declaration, the Notes shall
forthwith mature and become due and payable together with interest accrued
thereon, without presentment, demand, protest or notice, all of which are hereby
waived.

          At any time after the principal of, and interest on, all the Notes are
declared due and payable, the holders of 66% or more in aggregate principal
amount of the Notes then outstanding, by written notice to the Company, may
rescind and annul any such declaration and its consequences if (1) the Company
has paid all overdue interest on the Notes and the principal of, and premium, if
any, on any Notes which have become due otherwise by reason of such declaration,
and interest on such overdue principal and premium and (to the extent permitted
by applicable law) any overdue interest in respect of the Notes at the rate of
2% per annum above the then effective rate of interest on the Notes, (2) all
Events of Default, other than non-payment of amounts which have become due
solely by reason of such declaration, and all conditions and

                                      -30-
<PAGE>

events which constitute Events of Default or Potential Events of Default have
been cured or waived and (3) no judgment or decree shall have been entered for
the payment of any monies due pursuant to the Notes or this Agreement that has
not been vacated; but no such rescission and annulment shall extend to or affect
any subsequent Event of Default or Potential Event of Default or impair any
right consequent thereon.

          13.  Remedies on Default, etc.    If any Event of Default shall occur
               -------------------------
and be continuing, the holder of any Note at the time outstanding may, to the
extent permitted by applicable law, proceed to protect and enforce the rights of
such holder by an action at law, suit in equity or other appropriate proceeding,
whether for the specific performance of any agreement contained herein or in
such Note, or for an injunction against a violation of any of the terms hereof
or thereof, or in aid of the exercise of any power granted hereby or thereby or
by law or otherwise.  No course of dealing and no delay on the part of any
holder of any Note in exercising any right, power or remedy shall operate as a
waiver thereof or otherwise prejudice such holder's rights, powers or remedies.
No right, power or remedy conferred by this Agreement or by any Note upon any
holder thereof shall be exclusive of any other right, power or remedy referred
to herein or therein or now or hereafter available at law, in equity, by statute
or otherwise.

          14.  Subordination.
               -------------

          14.1  Notes Subordinate to Senior Debt.  The Company covenants and
                --------------------------------
agrees, and each holder of a Note, by its acceptance thereof, likewise covenants
and agrees, that, to the extent and in the manner hereinafter set forth in this
section, the payment of the principal of, premium, if any, and interest on each
and all the Notes and the repurchase, redemption or other retirement of the
Notes is hereby expressly made subordinate and subject in right of payment to
the prior payment in full in cash or cash equivalents or, as acceptable to the
holders of Senior Debt, in any other manner, of all Senior Debt in the manner
set forth in this section 14.  The terms of this section 14 are for the benefit
of, and shall be enforceable directly by, each holder of Senior Debt, and each
holder of Senior Debt whether now outstanding or hereafter created, incurred,
assumed or guaranteed shall be deemed to have acquired such Senior Debt in
reliance upon the covenants and provisions contained in this Agreement.

          14.2  Payment of Proceeds Upon Dissolution, Etc.  Upon any payment or
                -----------------------------------------
distribution of assets of the Company to creditors upon any liquidation,
dissolution, winding-up, reorganization, assignment for the benefit of
creditors, marshaling of assets or liabilities or any bankruptcy,
reorganization, receivership, insolvency or similar proceedings of the Company
or its property, whether voluntary or involuntary (each such event, if any,
herein sometimes referred to as a "Proceeding"):

          (a) The holders of Senior Debt shall receive payment in full in cash
or cash equivalents or, as acceptable to the holders of Senior Debt, in any
other manner, of all amounts due on or to become due on or in respect of all
Senior Debt (including any interest accruing thereon after the commencement of
any such Proceeding, whether or not allowed as a claim

                                      -31-
<PAGE>

against the Company in such Proceeding) or provision shall be made for such
payment in a manner acceptable to such holders before the holders of the Notes
are entitled to receive any payment or distribution whether by setoff,
exercising contractual or statutory rights or otherwise and whether in the form
of cash, stock or property or otherwise (excluding any payment or distribution
described in the last paragraph of section 14.2(b)), on account of the principal
of, premium, if any, interest on or any other obligation owing in respect of the
Notes or on account of any purchase, redemption or other acquisition of Notes by
the Company (all such payments, distributions, purchases, redemptions and
acquisitions, whether or not in connection with a Proceeding (but excluding any
payment or distribution described in the last paragraph of section 14.2(b)),
being herein referred to, individually and collectively, as a "Securities
Payment"); and

          (b) Any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, by set-off or otherwise,
to which the holders of the Notes would be entitled but for the provisions of
this section 14, shall be paid by the Company or the  liquidating trustee or
agent or other Person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Senior Debt or their representatives or trustees under any credit
agreement, indenture or other agreement under which any such Senior Debt may
have been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Senior Debt held or represented by each, to the extent necessary
to make payment in full in cash or cash equivalents or, as acceptable to the
holders of Senior Debt, in any other manner, of all Senior Debt remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Debt.

          In the event that, notwithstanding the foregoing provisions of this
section, the holder of any Notes shall have received in connection with any
Proceeding any Securities Payment before all Senior Debt is paid in full or
payment thereof is provided for in cash or cash equivalents, then and in such
event such Securities Payment shall be held in trust for the benefit of and paid
over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to make payment in full in
cash or cash equivalents or, as acceptable to the holders of the Senior Debt, in
any other manner, of all Senior Debt remaining unpaid after giving effect to any
concurrent payment to or for the holders of Senior Debt.

          For purposes of this section 14 only, the words "payment or
distribution" or "any payment or distribution of any kind or character, whether
in cash, property or securities" shall not be deemed to include a payment or
distribution of stock or securities of the Company provided for by a plan of
reorganization or readjustment authorized by an order or decree of a court of
competent jurisdiction in a reorganization proceeding under any applicable
bankruptcy law or of any other corporation provided for by such plan of
reorganization or readjustment, which stock or securities are subordinated in
right of payment to all then outstanding Senior Debt to substantially the same
extent, or to a greater extent than, the Notes are so subordinated as

                                      -32-
<PAGE>

provided in this section 14. The consolidation of the Company with, or the
merger of the Company into, another Person or the liquidation or dissolution of
the Company following the conveyance, transfer or lease of all or substantially
all of its properties and assets to another Person upon the terms and conditions
set forth in section 11.5 and so long as permitted under the terms of the Senior
Debt shall not be deemed a Proceeding for the purposes of this section if the
Person formed by such consolidation or into which the Company is merged or the
Person which acquires by conveyance, transfer or lease such properties and
assets, as the case may be, shall, as a part of such consolidation, merger,
conveyance, transfer or lease, comply with the conditions set forth in section
14.

          (c) To the extent any payment of Senior Debt (whether by or on behalf
of the Company, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or
other similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then if such payment is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Senior Debt or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

          14.3  No Payment When Senior Debt in Default.  In the event that any
                --------------------------------------
Senior Payment Default (as defined below) shall have occurred and be continuing,
then no Securities Payment whether by setoff, exercising contractual or
statutory rights or otherwise and whether in the form of cash, stock or property
or otherwise shall be made, unless and until such Senior Payment Default shall
have been cured or waived in writing or shall have ceased to exist or all
amounts then due and payable in respect of such Senior Debt (including, without
limitation, amounts that have become and remain due by acceleration) shall have
been paid in full in cash.  "Senior Payment Default" means any default in the
payment of the principal of, premium, if any, or interest on any Senior Debt
when due, whether at the stated maturity of any such payment or by declaration
of acceleration, call for redemption, notice of the exercise of an option to
require such repayment, mandatory payment or prepayment or otherwise.

          In the event that any Senior Nonmonetary Default (as defined below)
shall have occurred and be continuing, then, upon the receipt by the Company of
written notice of such Senior Nonmonetary Default from the Administrative Agent
to which such Senior Nonmonetary Default relates or, if no loans or other
amounts are then outstanding under the Credit Agreement or any renewal,
extension or refunding thereof, and the Credit Agreement and any such renewal,
extension or refunding have been terminated, upon receipt of such notice by or
on behalf of any other holder or holders of Senior Debt in an aggregate amount
in excess of $25,000,000, no Securities Payment shall be made whether by setoff,
exercising contractual or statutory rights or otherwise and whether in the form
of cash, stock or property or otherwise during the period (the "Payment Blockage
Period") commencing on the date of such receipt by the Company of such written
notice and ending on the earlier of (a) the date, if any, on which the Senior
Debt to which such Senior Nonmonetary Default relates is discharged or such
Senior Nonmonetary Default

                                      -33-
<PAGE>

shall have been cured or waived in writing or shall have ceased to exist and any
acceleration of Senior Debt to which such Senior Nonmonetary Default relates
shall have been rescinded or annulled and (b) the 179th day after the date of
receipt of such written notice. No more than one Payment Blockage Period may be
commenced with respect to the Notes during any period of 360 consecutive days
and there shall be a period of at least 181 consecutive days in each period of
360 consecutive days when no Payment Blockage Period is in effect. Following the
commencement of any Payment Blockage Period, the holders of Senior Debt shall be
precluded from commencing a subsequent Payment Blockage Period until the
conditions set forth in the preceding sentence shall have been satisfied. For
all purposes of this paragraph, no Senior Nonmonetary Default that existed and
was continuing on the date of commencement of any Payment Blockage Period with
respect to the Senior Debt initiating such Payment Blockage Period shall be, or
may be made, the basis for the commencement of a subsequent Payment Blockage
Period by any holder of Senior Debt or any representative or trustee under any
indenture under which any such Senior Debt may have been issued unless such
Senior Nonmonetary Default shall have been cured for a period of not less than
90 consecutive days. "Senior Nonmonetary Default" means any default (other than
a Senior Payment Default), under the terms of any instrument or agreement
pursuant to which any Senior Debt is outstanding, permitting one or more holders
of such Senior Debt or any representative or trustee under any indenture under
which any such Senior Debt may have been issued to declare such Senior Debt due
and payable prior to the date on which it would otherwise become due and
payable.

          In the event that, notwithstanding the foregoing, the Company shall
make any Securities Payment to any holder prohibited by the foregoing provisions
of this section 14.3, then in such event such Securities Payment shall be held
in trust and paid over and delivered forthwith to the representatives or trustee
under any indenture under which any such Senior Debt may have been issued
ratably according to the aggregate amounts remaining unpaid on account of the
Senior Debt held or represented by under the Senior Debt or, if there is no such
representative or trustee with respect to such Senior Debt, to the holders of
such Senior Debt.

          The provisions of this section 14.3 shall not apply to any Securities
Payment with respect to which section 14.2 hereof would be applicable.

          14.4  Acceleration of Subordinated Debt.  If an Event of Default
                ---------------------------------
shall have occurred and be continuing (other than an Event of Default pursuant
to paragraphs (h) or (i) of section 12), the holders of the Notes shall give the
holders of the Senior Debt not less than 30 days prior written notice before
accelerating the Notes which notice shall state it is a "Notice of Intent to
Accelerate".  Upon such declaration, the holders of Senior Debt outstanding at
the time such Subordinated Debt so becomes due and payable shall be entitled to
receive payment in full in cash, cash equivalents or, as acceptable to the
holders of the Senior Debt, in any other manner on all amounts due or to become
due on or in respect of such Senior Debt, before the Company may make, and
before any holder of Subordinated Debt is entitled to receive, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
securities or other property on account of any Subordinated Debt.  All payments
in respect of the

                                      -34-
<PAGE>

Subordinated Debt postponed under this section 14.4 shall be immediately due and
payable upon the termination of such postponement; the remittance in full of
such payments by the Company in accordance with the terms of the this Agreement
and the acceptance thereof by the holders of the Notes shall be deemed to
constitute a cure by the Company and a waiver by the holders of the Notes of any
Event of Default that existed immediately prior to such remittance and
acceptance to the extent that such Event of Default existed solely as a
consequence of the previous non-payment of such postponed payments during such
period of postponement.

          14.5  Payment Permitted If No Default.  Nothing contained in this
                -------------------------------
section 14 or elsewhere in this Agreement or in any of the Notes shall prevent
the Company, at any time except during the pendency of any Proceeding referred
to in section 14.2 or under the conditions described in section 14.3, from
making Securities Payments in accordance with the terms of this Agreement.
Nothing in this section 14 shall have any effect on the right of the holders to
accelerate the maturity of the Notes upon the occurrence of an Event of Default,
but, in that event, no payment may be made in violation of the provisions of
this section 14 with respect to the Notes.  If payment of the Notes is
accelerated because of an Event of Default, the Company shall promptly notify
the holders of the Senior Debt (or their representatives) of such acceleration.

          14.6  Subrogation To Rights of Holders of Senior Debt.  Subject to
                -----------------------------------------------
the payment in full in cash or cash equivalents, or as acceptable to the holders
of Senior Debt, in any other manner, of all Senior Debt, the holders of the
Notes shall be subrogated to the rights of the holders of such Senior Debt to
receive payments and distributions of cash, property and securities applicable
to the Senior Debt until the principal of, premium, if any, and interest on the
Notes shall be paid in full.  For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the holders of the Notes would be entitled except for the
provisions of this section 14, and no payments pursuant to the provisions of
this section 14 to the holders of Senior Debt by holders of the Notes, shall, as
among the Company, its creditors other than holders of Senior Debt and the
holders of the Notes, be deemed to be a payment or distribution by the Company
to or on account of the Senior Debt.

          14.7  Provisions Solely To Define Relative Rights.  The provisions
                -------------------------------------------
of this section 14 are and are intended solely for the purpose of defining the
relative rights of the holders of the Notes on the one hand and the holders of
Senior Debt on the other hand.  Nothing contained in this section 14 or
elsewhere in this Agreement or in the Notes is intended to or shall (a) impair,
as among the Company, its creditors other than holders of Senior Debt and the
holders of the Notes, the obligation of the Company, which is absolute and
unconditional (and which, subject to the rights under this section 14 of the
holders of Senior Debt, is intended to rank equally with all other general
obligations of the Company), to pay to the holders of the Notes the principal
of, premium, if any, and interest on the Notes as and when the same shall become
due and payable in accordance with their terms; or (b) affect the relative
rights against the Company of the holders of the Notes and creditors of the

to any holder (or Transferee) in respect of any amounts pursuant to such
paragraph (a) if such holder (or Transferee), in addition to complying with the

Borough as such place of payment, in which case the principal office of such
other bank or trust company shall thereafter be such place of payment.

          18.2  Home Office Payment.  So long as you or your nominee shall be

cost and expenses of preparing and reproducing this Agreement and the Notes, of

and compliance with all agreements and conditions contained herein on its part
to be performed or complied with; (b) the cost of delivering to your principal
office, insured to your satisfaction, the Notes sold to you hereunder and any

finders and, subject to section 16, any and all liabilities with respect to any
taxes (including interest and penalties but excluding taxes measured by or
payable with respect to gross or net income) which may be payable in respect of
the execution and delivery of this Agreement, the issue of the Notes and any
amendment or waiver under or in respect of this Agreement and the Notes. The
obligation of the Company under this section 18.3 shall survive any disposition
or payment of the Notes and the termination of this Agreement.

          19.  Survival of Representations and Warranties.  All representations
               ------------------------------------------
and warranties contained in this Agreement or made in writing by or on behalf of
the Company in connection with the transactions contemplated by this Agreement

this Agreement and any disposition or payment of the Notes. All statements
contained in any certificate or other instrument delivered by or on behalf of
the Company pursuant to this Agreement shall be deemed representations and
warranties of the Company under this Agreement.

          20.  Amendments and Waivers.  Any term of this Agreement or of the
               ----------------------
Notes may be amended and the observance of any term of this Agreement or of the
Notes may be waived (either generally or in a particular instance and either
retroactively or prospectively) only with the written consent of  the Company
and the Required Holders (subject to section 17); provided that, without the
                                                  --------

          22.  Indemnification.  The Company will indemnify and hold harmless
               ---------------
each holder of Notes and each person who controls a holder within the meaning of
the Securities Act or the Exchange Act and each of the holder's subsidiaries and
each holder's respective directors, officers, employees, agents and advisors
(any and all of whom are referred to as the "Indemnified Party") from and
against any and all losses, claims, damages and liabilities, whether joint or
several (including all legal fees or other expenses reasonably incurred by
counsel for any Indemnified Party in connection with the preparation for or
defense of any pending or threatened third party claim, action or proceeding,
whether or not resulting in any liability), to which such Indemnified Party may
become subject (whether or not such Indemnified Party is a party thereto) under
any applicable federal or state law or otherwise, caused by or arising out of,
the Financing Transactions, or this Agreement or any transaction contemplated
hereby or thereby (including, without limitation, any of the foregoing relating
to the violation of, non-compliance with or liability under any Environmental
Law applicable to the operations of the Company or its Subsidiaries), other
than, with respect to any Indemnified Party, losses, claims, damages or
liabilities that are the result of the gross negligence or willful misconduct of
such Indemnified Party.

          Promptly after receipt by an Indemnified Party of notice of any claim,
action or proceeding with respect to which an Indemnified Party is entitled to
indemnity hereunder, such Indemnified Party will notify the Company of such
claim or the commencement of such action or proceeding; provided that the
                                                        --------
failure of an Indemnified Party to give notice as provided herein shall not
relieve the Company of its obligations under this section 22 with respect to
such Indemnified Party, except to the extent that the Company is actually
prejudiced by such failure. The Company will assume the defense of such claim,
action or proceeding and will employ counsel reasonably satisfactory to the
Indemnified Party and will pay the fees and expenses of such counsel.
Notwithstanding the preceding sentence, the Indemnified Party will be entitled,
at the expense of the Company, to employ counsel separate from counsel for the
Company and for any other party in such action if the Indemnified Party
reasonably determines that a conflict of interest or other reasonable basis
exists which makes representation by counsel chosen by the Company not
advisable, but the Company will not be obligated to pay the fees and expenses of
more than one counsel for all Indemnified Parties.

                                      -58-

state securities and "blue sky" laws and regulations, at any time sell to one or
more Eligible Assignees ("Participants") participating interests in any Note
owned by such holder, the Commitments of such holder or any other interest of
such holder hereunder. In the event of any such sale by a holder of a
participating interest to a Participant, such holder's obligations under this
Agreement to the Company and any other holder shall remain unchanged, such
holder shall remain solely responsible for the performance thereof, such holder
shall remain the holder of any such Note for all purposes under this Agreement,
and the Company shall continue to deal solely and directly with such holder in
connection with such holder's rights and obligations under this Agreement.  No
holder shall be entitled to create in favor of any Participant, in the
participation  agreement pursuant to which such Participant's participating
interest shall be created or otherwise, any right to vote on,  consent to or
approve any matter relating to this Agreement except for those specified in
clauses (a) and (b) of section 20.  The Company also agrees that each
Participant shall be entitled to the benefits of section 16 with respect to its
participation in the Commitments and the Notes outstanding from time to time as
if it were a holder; provided that, in the case of section 16, such Participant

further, that no Participant shall be entitled to receive  any greater amount
- -------
pursuant to such section than the transferor holder would have been entitled to
receive in respect of the amount of the participation transferred by such
transferor holder to such Participant had no such transfer occurred.

          23.3  Assignments.  Subject to section 24, any holder may, in
                -----------

to time assign to any other holder or to an Eligible Assignee (an "Assignee")
all or any part of its Notes and Commitments pursuant to an assignment and
acceptance executed by such Assignee and such assigning holder and delivered to
the Company for acceptance and recording in the Register (an "Assignment and
Acceptance"); provided that, in the case of any such assignment to an Eligible
              --------

of less than all the Notes and Commitments of the assigning holder, the sum of
the aggregate principal amount of the assigning holder's remaining Notes and the
aggregate amount of Unused Commitment is not less than $5,000,000 (or such
lesser amount as may be agreed to by the Company). Upon such execution,
delivery, acceptance and recording, from and after the effective date determined

a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a holder hereunder, and (ii) the assigning
holder thereunder shall, to the extent provided in such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all or the remaining portion of an
assigning holder's rights and obligations under this Agreement, such assigning
holder shall cease to be a party hereto but shall be entitled to the benefits of
section 16 in respect of the period prior to such assignment).

          23.4  Register.  The Company shall maintain a copy of each Assignment
                --------
and Acceptance delivered to it and a register (the "Register") for the
recordation of the names and addresses of the holders, the registered owners of
the Obligations evidenced by the Notes and the principal amount of the Notes
owing to each holder from time to time. The entries in the Register shall be
prima facie evidence of the accuracy thereof, and the Company and the holders
shall treat each Person whose name is recorded in the Register as the owner of a
Note hereunder as the owner thereof for all purposes of this Agreement,
notwithstanding any notice to the contrary. Any assignment or transfer of all or
part of any Note shall be registered on the Register only upon surrender for
registration of assignment or transfer of such Note, duly endorsed by (or
accompanied by a written instrument of assignment or transfer duly executed by)
the holder thereof, and thereupon one or more new Note(s) in the same aggregate
principal amount shall be issued to the designated Assignee(s) and the old Note
shall be returned to the Company marked "canceled". The Register shall be
available for inspection by any holder at any reasonable time and from time to
time upon reasonable prior notice.

Company pursuant to this Agreement or which has been delivered to such holder by
or on behalf of the Company in connection with such holder's credit evaluation
of the Company and its Subsidiaries prior to becoming a party to this Agreement;
provided that no such disclosure may be made unless such Transferee or
- --------
prospective Transferee and its advisers and agents shall have executed and
delivered to the Company an agreement reasonably acceptable to the Company to
keep such information confidential.

          23.6  Assignment to Federal Reserve Bank.  Nothing contained herein

satisfactory to the Company of the loss, theft, destruction or mutilation of any
Note and, in the case of any such loss, theft or destruction of any Note, upon
delivery of an indemnity bond in such reasonable amount as the Company may
determine (or, in the case of any Note held by you or another institutional
holder or your or its nominee, of an indemnity agreement from you or such other
holder) or, in the case of any such mutilation, upon the surrender of such Note
for cancellation to the Company at its principal office, the Company at its
expense will execute and deliver, in lieu thereof, a new Note in the unpaid
principal amount of such lost, stolen, destroyed or mutilated Note, dated so
that there will be no loss of interest on such Note and otherwise of like tenor.
Any Note in lieu of which any such new Note has been so executed and delivered
by the Company shall not be deemed to be an outstanding Note for any purpose of
this Agreement.

          (a) You shall not engage in any remarketing efforts (i) prior to
October 23, 1999, with respect to any assignment of any Unused Commitment
related to the Series A Note Commitment or any Series A Notes and (ii) prior to
October 23, 1999, with respect to any assignment of any Unused Commitment
related to the Series B Note Commitment or any Series B Notes except as provided

the period in which you are restricted from remarketing the Notes.  The Company
will consider any such request and will not object to any such request if it
concludes (in the exercise of its business judgement based on such criteria as
it considers appropriate) that any such remarketing will not impair the ability
of the Company to any High Yield Offering.  The restrictions set forth in this
section 24 shall not apply to any remarketing of the Notes to any of your
Affiliates.

          (b) You shall provide the Company at least with 60 days prior written

assigned (a "Remarketing Transfer"). Upon receipt of a Remarketing Notice, the
Company and its Subsidiaries shall cooperate with you and your underwriters or
agents in each remarketing effort undertaken by you.  Such cooperation shall
include, if requested by you, (i) the Company providing customary information in
respect of the Company and its Subsidiaries and making customary representations
and warranties with respect to such information in connection with any Offering
and, if required by the Securities Act, the Company acting as co-registrant,
issuer or co-issuer of such Offering, (ii) senior officers of the Company and
its Subsidiaries participating to a reasonable degree and upon reasonable prior
notice, in the "road show" for any Offering or in meetings with prospective
transferees or assignees of the Notes and, (iii) appropriate personnel from the
Company and its Subsidiaries assisting in the drafting of a registration
statement or offering circular used in marketing of any Offering; provided that
                                                                  --------
the Company may elect to combine the registration of such Offering with the
registration of any of the Company's other High Yield Debt.  The Company will
promptly

                                      -61-
<PAGE>

after delivery of a Remarketing Notice, upon your request, direct its counsel
(i) to prepare required documentation for Refinancing Securities and/or any
required amendments to this Agreement to permit a Remarketing Transfer or (ii)
to review any such documentation prepared by your counsel, and the Company will
work diligently with you to finalize such documentation and issue such
Refinancing Securities in the manner you request.

          (c) In connection with any Remarketing Transfer involving a sale of
Notes, the holders of the Notes or Refinancing Securities that are the subject
of such Remarketing Transfer shall, if you so request, be granted the right to
decline any optional or mandatory prepayments of such Notes or Refinancing
Securities (excluding regularly scheduled installments of principal) for a
period of up to five years from the date of consummation of such Remarketing

$50,000,000 aggregate principal amount). The expiration date for the Expansion
Notes issued to finance a particular Expansion Area shall be October 23, 2009.
The Company acknowledges that your obligation to purchase Expansion Notes is
contingent on:

     (a) the Company irrevocably committing to purchase one mobile switching

     either pursuant to the Procurement Contract or under a new procurement
     contract acceptable to the Company and the Vendor;

     service marks, roaming, access to the AT&T network with seamless
     integration for customers;

     (c) an agreement among AT&T PCS, TWR and the other parties to the
     Stockholders' Agreement (in each case together with the Affiliated
     Successors (as defined in the Stockholders' Agreement) that none of them
     will offer any Company Communications Services (as defined in the
     Stockholders' Agreement) in such Expansion Area (other than the right of
     AT&T PCS to offer resale services similar to those set forth in Section 8.6
     of the Stockholders' Agreement);

     (d) the Company having received either cash equity contributions or
     irrevocable commitments to provide, over a time frame acceptable to you,
     cash equity contributions, per POP in such Expansion Area in an amount of
     not less than $10;

     (e) the Company having Licenses covering such Expansion Area that (i) are
     in full force and effect with no pending appeal, and (ii) are not subject
     to any pending or, to the knowledge of the Company, threatened revocation
     or termination proceeding or action;

     (f) the Company being in compliance with all Licenses covering such
     Expansion Area in all material respects; and

     (g) the Company and the Vendor having into a new procurement contract or
     amendment of the Procurement Contract, as described above.

                                      -64-
<PAGE>

Your exclusivity rights under the Procurement Contract with respect to the
Expansion Area shall not terminate if any of these conditions are not satisfied
and as a result you do not purchase any Expansion Notes.  The Company's and your

     (B) the number of POPs in Expansion Areas for which Expansion Notes have
     been or concurrent therewith are being issued and the denominator of which
     is 16,800,000; and

     (ii)  enter into an agreement and/or an amendment to this Agreement related
     to the purchase of the Expansion Notes.

provisions of this Agreement, if any, shall apply) as those contained in Article
4 and Article 5 of the Indenture (including, to the extent applicable and solely

contained therein) and the same events of default as those contained in Article
6 of the Indenture (including, to the extent applicable and solely for the
purposes of applying and interpreting such provisions, all defined terms
contained therein), in each case, with such conforming changes as may be
necessary or appropriate to reflect that the Series B Notes are not being issued
under the Indenture and do not have the benefit of any guarantees by the
Subsidiaries and with such other modifications as the parties may agree.

          31.  Existing Events of Default; Effectiveness.  Prior to the date
               -----------------------------------------

          A. Section 3.1 of the Stockholders' Agreement shall be amended and
             restated in its entirety as follows:

     "3.1 Board of Directors Upon IPO Date.  Effective upon the IPO Date, the
          --------------------------------
Board of Directors shall consist of nine (9) directors; provided, however, that
                                                        --------  -------

of the Class A Voting Common Stock Beneficially Owned by the Cash Equity

          (b) Gerald Vento (so long as he is an officer of the Company and the
Management Agreement remains in full force and effect);

          (c) Thomas Sullivan (so long as he is an officer of the Company and
the Management Agreement remains in full force and effect);

          (d) One (1) individual nominated by AT&T PCS pursuant to the Restated
Certificate in its capacity as holder of Series A Preferred Stock (the "Series A

(1) individual selected by the holders of Voting Preference Stock, who shall be

Directors shall consist of seven (7) directors elected in accordance with
Section 3.1(a)-(d) and (e)(i).

     In the event that Mr. Vento or Mr. Sullivan shall cease to be an officer of

than one-quarter of the number of shares of Common Stock Beneficially Owned by
the Cash Equity Investors on July 17, 1998, the number of directors the Cash

Stock Options described herein.

        2.  Administration.  The Plan will be administered by the Board of
            --------------
Directors of the Company (the "Board"). The Board is authorized, subject to the
provisions of the Plan, to establish such rules and regulations as it deems
necessary for the proper administration of the Plan and to make such
determinations and interpretations and to take such action or inaction in
connection with the Plan and any Stock Options granted hereunder as it deems
necessary or advisable. All determinations and interpretations made by the Board
shall be binding and conclusive on all participants and their legal
representatives. The Board may correct any defect or supply any omission or
reconcile any inconsistency in the Plan or in any option agreement in the manner
and to the extent it shall deem expedient to effectuate the purposes of the
Plan. No member of the Board, and no officer or employee of the Company, shall
be liable for any act or failure to act hereunder, by any other member of the
Board or any officer or employee or by any agent to whom duties in connection
with the administration of this Plan have been delegated or, except in
circumstances involving his bad faith, gross negligence or fraud, for any act or
failure to act by the member of the Board or any officer or employee.

        3.  Participants.  The Board, in its sole discretion may designate
            ------------
employees, officers and directors of the Company and its affiliates from time to
time to receive Stock Options under the Plan. Designation of a participant in
any year shall not require the Board to designate such person to receive a Stock
Option in any other year or, once designated, to receive the same type or amount
of Stock Options as granted to the participant or any other participant in any
year. The Board shall consider such factors as it deems pertinent in selecting
participants and in determining the type and amount of their respective Stock
Options.

        4.  Shares Reserved under the Plan.  Subject to adjustment under
            ------------------------------
Section 6 below, there is hereby reserved for issuance under the Plan an
aggregate of 587,159 Common Shares. Such shares may be authorized but unissued
shares or may be shares issued and thereafter acquired by the Company. Any
shares subject to Stock Options may thereafter be subject to new options under
this Plan if there is a lapse, expiration or termination of any such options, or
if shares are issued under such options and thereafter are reacquired by the
Company pursuant to rights reserved by the Company upon issuance thereof.

- ---------------------
 *Amended October 18, 1999 by the Company's Board of Directors.
<PAGE>

        5.  Stock Options.  Stock Options will consist of awards from the
            -------------
Company, in the form of agreements, which will enable the holder to purchase a
specific number of Common Shares, at set terms and at a fixed purchase price.
Stock Options may be "incentive stock options" within the meaning of Section 422
of the Internal Revenue Code ("Incentive Stock Options") or Stock Options which
do not constitute Incentive Stock Options ("Nonqualified Stock Options"). The
Board will have the authority to grant to any participant one or more Incentive
Stock Options, Nonqualified Stock Options, or both types of Stock Options. Each
Stock Option shall be subject to such terms and conditions consistent with the
Plan as the Board may impose from time to time, subject to the following
limitations:

                (a)  Exercise Price.  Subject to Paragraph (e) below, each Stock
                     --------------
Option granted hereunder shall have such per-share exercise price as the Board
may determine at the date of grant.

                (b)  Payment of Exercise Price.  Options granted under the Plan
                     -------------------------
may provide for the payment of the exercise price by delivery of cash or a check
to the order of the Company in an amount equal to the exercise price of such
options, or by delivery to the Company of Common Shares already owned by the
participant having a Fair Market Value equal in amount to the exercise price of
the options being exercised or by any combination of such methods of payment.
The Fair Market Value of any Common Shares which may be delivered upon exercise
of an option shall be determined by the Board.

                (c)  Exercise Period.  Stock Options granted under the Plan
                     ---------------
shall be exercisable at such times and subject to such terms and conditions as
shall be determined by the Board. In addition, Stock Options shall not be
exercisable more than ten years after the date they are granted. All Stock
Options shall terminate at such earlier times and upon such conditions or
circumstances as the Board shall in its discretion set forth in such option at
the date of grant.

                (d)  Exercise of Options.  Each option granted under the Plan
                     -------------------
shall be exercisable either in full or in installments at such time or times and
during such period as shall be set forth in the agreement evidencing such
option, subject to the provisions of paragraph (c) above. To the extent that an
option to purchase Common Shares is not exercised by an optionee when it becomes
initially exercisable, it shall not expire but shall be carried forward and
shall be exercisable, on a cumulative basis, until the expiration of the
exercise period or such earlier time as the Board shall, in its sole discretion,
set forth in such option at the date of grant.

                (e)  Limitations on Incentive Stock Options.  Incentive Stock
                     --------------------------------------
Options may be granted only to participants who are employees of the Company at
the date of grant. The aggregate Fair Market Value (determined as of the time
the option is granted) of the Common Shares with respect to which Incentive
Stock Options are exercisable for the first time by a participant during any
calendar year (under all option plans of the Company) shall not exceed $100,000.
Incentive Stock Options may not be granted to any participant who, at the time
of grant, owns stock possessing (after the application of the attribution rules
of Section 424(d) of the

                                      -2-
<PAGE>

Internal Revenue Code) more than 10% of the total combined voting power of all
classes of stock of the Company, unless the option price is fixed at not less
than 110% of the Fair Market Value of the Common Shares on the date of grant and
the exercise of such option is prohibited by its terms after the expiration of
five years from the date of grant of such option.

                (f)  Redesignation as Nonqualified Stock Options.  Options
                     -------------------------------------------
designated as "incentive stock options" that fail to continue to meet the
requirements of Section 422 of the Internal Revenue Code shall be redesignated
as nonqualified options for Federal income tax purposes automatically without
further action by the Board on the date of such failure to continue to meet the
requirements of Section 422 of the Internal Revenue Code.

                (g)  Limitation of Rights in Shares.  The recipient of a Stock
                     ------------------------------
Option shall not be deemed for any purpose to be a shareholder of the Company
with respect to any of the shares subject thereto except to the extent that the
Stock Option shall have been exercised and, in addition, a certificate shall
have been issued and delivered to the participant.

        6.  Adjustment Provisions.
            ---------------------
                (a)  If the Company shall at any time change the number of
issued Common Shares without new consideration to the Company (such as by stock
dividend, stock split, recapitalization, reorganization, exchange of shares,
liquidation, combination or other change in corporate structure affecting the
Common Shares) or make a distribution of cash or property which has a
substantial impact on the value of issued Common Shares, the total number of
shares available for Stock Options under this Plan shall be appropriately
adjusted, and the number of shares covered by each outstanding Stock Option and
the option exercise price of each outstanding Stock Option shall be adjusted so
that the net value of such Stock Option shall not be changed.

                (b)  In the case of any sale of assets, merger, consolidation,
combination or other corporate reorganization or restructuring of the Company
with or into another corporation which results in the outstanding Common Shares
being converted into or exchanged for different securities, cash or other
property, or any combination thereof (an "Acquisition"), subject to the
provisions of this Plan and any limitation applicable to the Stock Option,
including without limitation, the termination of any unexercised options upon
the sale of the Company's assets, any participant to whom a Stock Option has
been granted shall have the right thereafter and during the term of the Stock
Option, to receive upon exercise thereof the Acquisition Consideration (as
defined below). The term "Acquisition Consideration" shall mean the kind and
amount of securities, cash or other property or any combination thereof
receivable in respect of one Common Share upon consummation of an Acquisition.

                (c)  Notwithstanding any other provision of this Plan, the Board
may authorize the issuance, continuation or assumption of Stock Options or
provide for other equitable adjustments after changes in the Common Shares
resulting from any merger,

                                      -3-
<PAGE>

consolidation, sale of assets, acquisition of property or stock,
recapitalization, reorganization or similar occurrence upon such terms and
conditions as it may deem equitable and appropriate.

        7.  Nontransferability.  Each Stock Option granted under the Plan to a
            ------------------
participant shall not be transferable by him otherwise than by law or by will or
the laws of descent and distribution, and shall be exercisable, during his
lifetime, only by him (or his legal representative in the case of
incapacitation).  In the event of the death of a participant while the
participant is rendering services to the Company, each Stock Option theretofore
granted to him shall be exercisable during such period after his death as the
Board shall in its discretion set forth in such option or right at the date of
grant (but not beyond the stated duration of the option or right) and then only:

                (i)  By the executor or administrator of the estate of the
deceased participant or the person or persons to whom the deceased participant's
rights under the Stock Option shall pass by will or the laws of descent and
distribution; an d

                (ii) To the extent that the deceased participant was entitled to
do so at the date of his death.

        8.  Other Provisions.  Stock Options under the Plan may also be subject
            ----------------
to such other provisions (whether or not applicable to any other Stock Options
under the Plan) as the Board, in its sole discretion, determines appropriate,
including without limitation, provisions determining the effect that a
termination of employment shall have on the participant's Stock Options,
provisions for the installment purchase of Common Shares under Stock Options,
provisions to assist the participant in financing the acquisition of Common
Shares, provisions for the forfeiture of, or restrictions on resale or other
disposition of Common Shares acquired under any form of Stock Option, provisions
for the acceleration of exercisability or vesting of Stock Options in the event
of a change of control of the Company, provisions for the payment of the value
of Stock Options to participants in the event of a change of control of the
Company, provisions for the forfeiture of, or provisions to comply with Federal
and state securities laws, or understandings or conditions as to the
participant's employment in addition to those specifically provided for under
the Plan. Notwithstanding the foregoing, such additional provisions shall not
cause any Incentive Stock Option granted under the Plan to fail to qualify as an
Incentive Stock Option within the meaning of Section 422 of the Code.

        9.  Fair Market Value.  For purposes of this Plan and any Incentive
            -----------------
Stock Options awarded hereunder, Fair Market Value of Common Shares shall be the
amount determined in good faith by the Board from time to time as the fair
market value of the Common Shares of the Company.

        10. Withholding.  All payments or distributions or deliveries made
            -----------
pursuant to the Plan shall be net of any amounts required to be withheld
pursuant to applicable federal, state and local tax withholding requirements. If
the Company is required to issue Common Shares pursuant

                                      -4-
<PAGE>

to the exercise of Stock Options, it may require the participant to remit to it
an amount sufficient to satisfy such tax withholding requirements prior to the
delivery of any certificates for such Common Shares. The Board may, in its
discretion and subject to such rules as it may adopt, permit a participant to
pay all or a portion of the federal, state and local withholding taxes arising
in connection with the exercise of a Stock Option, by electing to have the
Company withhold Common Shares having a Fair Market Value equal to the amount
required to be withheld.

        11.  Tenure.  A participant's right, if any, to continue to serve the
             ------
Company as an officer, employee, director or otherwise, shall not be enlarged or
otherwise affected by his designation as a participant under the Plan, nor shall
this Plan in any way interfere with the right of the Company, subject to the
terms of any separate employment agreement to the contrary, at any time to
terminate such employment or to increase or decrease the compensation of the
participant from the rate in existence at the time of the grant of a Stock
Option. Whether an authorized leave of absence, or absence in military or
government service, shall constitute termination of employment shall be
determined by the Board at the time.

        12.  Other Employee Benefits.  The amount of any compensation that may
             -----------------------
be deemed to be received by an participant as a result of the grant of a Stock
Option, the vesting of a Stock Option, the exercise of a Stock Option or the
sale of Common Shares received upon such exercise will not constitute
compensation with respect to which any other participant benefits of such
employee are determined, including, without limitation, benefits under any
bonus, pension, profit sharing, life insurance or salary continuation plan,
unless separate provision to the contrary is contained in such other plan.

        13.  Duration, Amendment and Termination.  No Stock Option shall be
             -----------------------------------
granted after December 31, 2008; provided, however, that the terms and
conditions applicable to any Stock Option granted prior to such date shall
continue to have force and effect in accordance with the participant's stock
option agreement, and such agreement may thereafter be amended or modified by
mutual agreement between the Company and the participant or such other persons
as may then have an interest therein. Also, by mutual agreement between the
Company and a participant hereunder, under this Plan or under any other present
or future plan of the Company, Stock Options may be granted to such participant
in substitution and exchange for, and in cancellation of, any Stock Options
previously granted such participant under this Plan, or any other present or
future plan of the Company. The Board may amend the Plan from time to time or
terminate the Plan at any time. However, no action authorized by this Section 13
shall reduce the amount of any existing Stock Option or change the terms and
conditions thereof without the participant's consent.

        14.  Governing Law.  This Plan and actions taken in connection herewith
             -------------
shall be governed and construed in accordance with the laws of the Commonwealth
of Virginia (regardless of the law that might otherwise govern under applicable
Virginia principles of conflict of laws).

                                      -5-

        15. Approval.  The Plan was adopted by the Board of the Company on
            --------
June 23, 1999 and amended by the Board on October 18, 1999.

                           INDEMNIFICATION AGREEMENT
                           -------------------------


          This Indemnification Agreement (this "Agreement") is made as of
__________, 1999, by and between TeleCorp PCS, Inc., a Delaware corporation (the
"Company"), and the individual whose name appears below the word "Indemnitee" on
the signature page (the "Indemnitee").  In consideration of the services of the
Indemnitee, and to induce the Indemnitee to continue to serve as a director
and/or officer, the Company and the Indemnitee agree as follows:


                                R E C I T A L S

     A.  The Indemnitee has agreed to serve as a director and/or officer of the
     Company and in such capacity will render valuable services to the Company.

     B.  The Company has concluded that insurance and statutory indemnity
     provisions may provide inadequate protection to individuals requested to
     serve as its directors and officers.

     C.  To induce and encourage the Indemnitee to serve as a director and/or
     officer of the Company, the Company's Board of Directors has decided that
     this Agreement is not only reasonable and prudent, but necessary, to
     promote and ensure the best interests of the Company and its stockholders.

                               1.   Definitions
                                    -----------
As used in this Agreement:

1.1  "Agent" means a director, officer, employee or agent of the Company or of
     any other corporation, partnership, joint venture, trust, employee benefit
     plan, or other enterprise that the Indemnitee served in any of such
     capacities at the request of the Company.

and/or assets as an entirety to, one or more entities that are not Subsidiaries
or other affiliates of the Company (a "Business Combination"), unless (1) as a
result of the Business Combination more than 50% of the outstanding voting power
generally in the election of directors of the surviving or resulting entity or a
parent thereof (the "Successor Entity") immediately after the reorganization
are, or will be, owned, directly or indirectly, by holders of the Company's
voting securities immediately before the Business Combination; and (2) no Person
(excluding
<PAGE>

the Successor Entity or an Excluded Person) beneficially owns, directly or
indirectly, more than 50% of the outstanding shares or the combined voting power
of the outstanding voting securities of the Successor Entity, after giving
effect to the Business Combination, except to the extent that such ownership
existed prior to the Business Combination; and (3) at least 50% of the members
of the board of directors of the entity resulting from the Business Combination
were members of the Board of Directors at the time of the execution of the
initial agreement, or of the action of the Board of Directors, providing for the

Exchange Act other than an Excluded Person becomes the beneficial owner (as

securities of the Company representing more than 50% of the combined voting
power of the Company's then outstanding securities entitled to then vote
generally in the election of directors of the Company, other than as a result of
(1) an acquisition directly from the Company, (2) an acquisition by the Company,
(3) an acquisition by any employee benefit plan (or related trust) sponsored or
maintained by the Company or a Successor Entity, or (4) an acquisition by an
entity pursuant to a transaction which is expressly excluded under clause (b)
above; or

     (d)  During any period not longer than two consecutive years, individuals
who at the beginning of such period constituted the Board of Directors cease to
constitute at least a majority thereof, unless the election, or the nomination
for election by the Company's stockholders, of each new member of the Board of
Directors was approved by a vote of at least three-fourths of the members of the
Board of Directors then still in office who were members at the beginning of
such period (including for these purposes, new members whose election or
nomination was so approved), but excluding for this purpose, any such individual
whose initial assumption of office occurs as a result of an actual or threatened
election contest with respect to the election or removal of directors or other
actual or threatened solicitation of proxies or consents by or on behalf of a
person other than the Board of Directors.

1.3  "Excluded Person" means (a) any person described in and satisfying the
     conditions of Rule 13d-1(b)(1) under the Exchange Act, (b) the Company, (c)

     of the Indemnitee, and any expenses of establishing a right to
     indemnification pursuant to this Agreement, to the extent actually and
     reasonably incurred by the Indemnitee in connection with any Proceeding.
     "Expenses" does not include the amount of judgments, fines, penalties or
     ERISA excise taxes actually levied against the Indemnitee.

1.5  "Indemnified Costs" means all Expenses, judgments, fines, penalties and
     ERISA excise taxes actually and reasonably incurred by the Indemnitee in
     connection with the investigation, defense, appeal, or settlement of any
     Proceeding.

1.6  "Person" means an individual, corporation, partnership, limited liability
     company, association, joint stock company, business trust, unincorporated
     organization, or other legal entity.

1.7  A "Potential Change in Control Event" will be deemed to have occurred if:

     (a) the Company enters into an agreement or arrangement that would
     constitute a Change in Control Event if consummated;

     (b) any person (including the Company) publicly announces an intention to
     take or to consider taking actions that would constitute a Change in
     Control Event if consummated; or

     (c) the Board of Directors adopts a resolution to the effect that, for
     purposes of this Agreement, a Potential Change in Control Event has
     occurred.

1.8  "Proceeding" means any threatened, pending or completed action, suit or
     proceeding (including appeals thereof), whether brought by or in the name
     of the Company or otherwise and whether of a civil, criminal or
     administrative or investigative nature, in which the Indemnitee is or will
     be a party at the time because the Indemnitee is or was an Agent, whether
     or not the Indemnitee is serving in such capacity at the time any liability
     or Expense is incurred for which indemnification or reimbursement is to be
     provided under this Agreement.

                             2.   Indemnification
                                  ---------------

2.1  Indemnification in Third Party Actions.  The Company will indemnify the
     --------------------------------------
     Indemnitee if the Indemnitee becomes a party to, is threatened to be made a
     party to, is a witness or other participant in, or is otherwise involved in
     any Proceeding (other than a Proceeding by or in the name of the Company to
     procure a judgment in its favor), because the Indemnitee is or was an
     Agent, against all Indemnified Costs, to the fullest extent permitted by
     applicable law. Any settlement must be approved in writing by the Company.

2.2  Indemnification in Proceedings By or In the Name of the Company.  The
     ---------------------------------------------------------------
     Company will indemnify the Indemnitee if the Indemnitee is a party to, is
     threatened to be made a party to, is a witness or other participant in, or
     is otherwise involved in any Proceeding by or in the name of the Company to
     procure a judgment in its favor because the Indemnitee was or is an Agent
     of the Company against all Expenses in connection with the defense or
     settlement of the Proceeding, to the fullest extent permitted by applicable
     law.

                                      -3-
<PAGE>

2.3  Partial Indemnification.  If the Indemnitee is entitled under any provision
     -----------------------
     of this Agreement to indemnification by the Company for some or a portion
     of, but not the total amount of, the Indemnified Costs, the Company will
     nevertheless indemnify the Indemnitee for the portion of the Indemnified
     Costs to which the Indemnitee is entitled.

2.4  Indemnification Hereunder Not Exclusive.  The indemnification provided by
     ---------------------------------------
     this Agreement is not exclusive of any other rights to which the Indemnitee
     may be entitled under the Company's Certificate of Incorporation, the
     Bylaws, any agreement, any vote of stockholders or disinterested directors,
     applicable law, or otherwise, both as to action in the Indemnitee's
     official capacity and as to action in another capacity on behalf of the
     Company.

2.5  Indemnification of Indemnified Costs of Successful Party.  Notwithstanding
     --------------------------------------------------------
     any other provisions of this Agreement, to the extent that the Indemnitee
     has been successful in defense of any Proceeding or in defense of any
     claim, issue or matter in the Proceeding, on the merits or otherwise,
     including, but not limited to, the dismissal of a Proceeding without
     prejudice, the Indemnitee will be indemnified against all Indemnified Costs
     incurred in connection therewith to the fullest extent permitted by
     applicable law.

2.6  Indemnified Costs Advanced.  The Indemnified Costs incurred by the
     --------------------------
     Indemnitee in any Proceeding will be paid promptly by the Company in
     advance of the final disposition of the Proceeding at the written request
     of the Indemnitee to the fullest extent permitted by applicable law. The
     advances to be made will be paid by the Company to the Indemnitee within 30
     days following delivery of the written request by Indemnitee to the
     Company, accompanied by substantiated documentation.

2.7  Limitations on Indemnification.  Notwithstanding anything to the contrary
     ------------------------------
     in this Agreement, the Company is not required to make payments to:

          (a) indemnify or advance Indemnified Costs with respect to Proceedings
     initiated or brought voluntarily by the Indemnitee and not by way of
     defense, except with respect to Proceedings brought to establish or enforce
     a right to indemnification under this Agreement or any other statute or law
     or otherwise as required under applicable law;

          (b) indemnify the Indemnitee for any Indemnified Costs for which
     payment is actually made to the Indemnitee under an insurance policy,
     except for any excess beyond the amount of payment under the policy;

          (c) indemnify the Indemnitee for any Indemnified Costs sustained in
     any Proceeding for an accounting of profits made from the purchase or sale
     by the Indemnitee of securities of the Company pursuant to Section 16(b) of
     the Securities Exchange Act of 1934, as amended, the rules and regulations
     promulgated thereunder and amendments thereto or similar provisions of any
     federal, state or local law;

                                      -4-
<PAGE>

          (d) indemnify the Indemnitee for any Indemnified Costs resulting from
     Indemnitee's conduct that is finally adjudged by a court of competent
     jurisdiction to have been willful misconduct, knowingly fraudulent or
     deliberately dishonest; or

          (e) indemnify the Indemnitee if a court of competent jurisdiction
     finally determines that such payment is unlawful.

                               3.   Presumptions
                                    ------------

3.1  Presumption Regarding Standard of Conduct.  The Indemnitee will be
     -----------------------------------------
     conclusively presumed to have met the relevant standards of conduct as
     defined by applicable law for indemnification pursuant to this Agreement
     unless a determination that the Indemnitee has not met the relevant
     standards is made by (a) the Board of Directors of the Company by a
     majority vote of a quorum consisting of directors who are not parties to
     the Proceeding, (b) the stockholders of the Company by majority vote, or
     (c) in a written opinion by independent legal counsel, selection of whom
     has been made by the Company's Board of Directors and approved by the
     Indemnitee.

3.2  Determination of Right to Indemnification.
     -----------------------------------------

     3.2.1  Burden.  If a claim under this Agreement is not paid by the Company
            ------
     within 30 days of receipt of written notice, the right to indemnification
     as provided by this Agreement will be enforceable by the Indemnitee in any
     court of competent jurisdiction. The burden of proving by clear and
     convincing evidence that indemnification or advances are not appropriate
     will be on the Company. Neither the failure of the directors, stockholders,
     or independent legal counsel to have made a determination before the
     commencement of the action that indemnification or advances are proper in
     the circumstances because the Indemnitee has met the applicable standard of
     conduct, nor an actual determination by the directors, stockholders or
     independent legal counsel that the Indemnitee has not met the applicable
     standard of conduct, will be a defense to the action or create a
     presumption that the Indemnitee has not met the applicable standard of
     conduct.

     3.2.2  Standard.  The Indemnitee's Expenses incurred in connection with
             --------
     any Proceeding concerning the Indemnitee's right to indemnification or
     advances in whole or in part pursuant to this Agreement will also be
     indemnified by the Company regardless of the outcome of the Proceeding,
     unless a court of competent jurisdiction determines that each of the
     material assertions made by the Indemnitee in the Proceeding was not made
     in good faith or was frivolous.

                             4.   Other Agreements
                                  ----------------

4.1  Change in Control Event.  If there is a Change in Control Event or a
     -----------------------
     Potential Change in Control Event of the Company (other than a Change in
     Control Event or Potential Change in Control Event that has been approved
     by a majority of the Company's Board

                                      -5-
<PAGE>

     of Directors who were directors immediately before the Change in Control
     Event or Potential Change in Control Event), then with respect to all
     matters thereafter arising concerning the rights of the Indemnitee to be
     indemnified for Indemnified Costs, the Company will seek legal advice only
     from independent counsel selected by the Indemnitee, and reasonably
     satisfactory to the Company, and who has not otherwise performed other
     services for the Company or the Indemnitee within the last three years
     ("Special Independent Counsel"). The Special Independent Counsel, among
     other things, will render its written opinion to the Company and the
     Indemnitee as to whether and to what extent the Indemnitee would be
     permitted to be indemnified under applicable law. The Company will pay the
     reasonable fees and expenses of the Special Independent Counsel.

4.2  Maintenance of Liability Insurance.
     ----------------------------------

     4.2.1 Affirmative Covenant of the Company. While the Indemnitee continues
           -----------------------------------
     to serve as a director or officer of the Company, and thereafter while the
     Indemnitee is subject to any possible Proceeding, the Company will promptly
     obtain and maintain in full force and effect directors' and officers'
     liability insurance ("D&O Insurance") in reasonable amounts from reputable
     insurers. The Company has no obligation, however, to obtain or maintain D&O
     Insurance if it determines in good faith that insurance is not reasonably
     available, the premium costs for insurance are disproportionate to the
     amount of coverage provided, the coverage provided by insurance is so
     limited by exclusions that it provides an insufficient benefit, or the
     Indemnitee is covered by similar insurance maintained by a subsidiary of
     the Company. If at the time it receives a notice a Proceeding has commenced
     the Company has D&O Insurance, the Company will give prompt notice of such
     commencement to the insurers as required by the respective policies. The
     Company will thereafter take all necessary or desirable action to cause
     such insurers to pay, on behalf of the Indemnitee, all amounts payable as a
     result of such proceeding in accordance with the terms of such policies.

     4.2.2  Indemnitee Named as Insured.  In all D&O Insurance policies, the
            ---------------------------
     Indemnitee will be named as an insured in a manner that provides the
     Indemnitee the same rights and benefits accorded to the most favorably
     insured of the Company's directors and officers.

4.3  Agreement to Serve.  Indemnitee will serve or continue to serve as an Agent
     ------------------
     of the Company for so long as the Indemnitee is duly elected or appointed
     or until the Indemnitee voluntarily resigns. Indemnitee will give notice to
     the Company at least thirty (30) days before voluntarily resigning.


4.4  Effect of this Agreement on Employment Agreement.  Any present or future
     ------------------------------------------------
     employment agreement between the Indemnitee and the Company is not modified
     by this Agreement. Nothing contained in this Agreement creates in the
     Indemnitee any right of continued employment.

                                      -6-
<PAGE>

4.5  Nature of Rights; Separability.  The rights afforded to the Indemnitee by
     ------------------------------
     this Agreement are contract rights and may not be diminished, eliminated or
     otherwise affected by amendments to the Company's Certificate of
     Incorporation, Bylaws or agreements, including D&O Insurance policies. Each
     provision of this Agreement is a separate and distinct agreement and
     independent of the others, so that if any provision of this Agreement is
     held to be invalid or unenforceable for any reason, the invalidity or
     unenforceability will not affect the validity or enforceability of the
     other provisions. To the extent required, any provision of this Agreement
     may be modified by a court of competent jurisdiction to preserve its
     validity and to provide the Indemnitee with the broadest possible
     indemnification permitted under applicable law.

4.6  Savings Clause.  If this Agreement or any portion of it is invalidated on
     --------------
     any ground by any court of competent jurisdiction, then the Company will
     nevertheless indemnify the Indemnitee as to Indemnified Costs with respect
     to any Proceeding to the full extent permitted by any applicable portion of
     this Agreement that is not invalidated, or by any applicable law.

4.7  Repayment of Indemnified Costs.  The Indemnitee will reimburse the Company
     ------------------------------
     for all Indemnified Costs paid by the Company in defending any Proceeding
     against the Indemnitee if and only to the extent that a court of competent
     jurisdiction finally decides that the Indemnitee is not entitled to be
     indemnified by the Company for such Indemnified Costs under the provisions
     of applicable law, the Company's Bylaws, Certificate of Incorporation, this
     Agreement, or otherwise. The Indemnitee will repay such amounts advanced
     only if, and to the extent that, it is ultimately determined that
     Indemnitee is not entitled to be indemnified for such Indemnified Costs by
     the Company pursuant to this Agreement.

4.8  Repayment.  The Indemnitee will promptly repay to the Company any amounts
     ---------
     paid to the Indemnitee pursuant to other rights of indemnification or under
     any insurance policy, to the extent those payments are duplicative of
     payments under this Agreement.

                        5.   Indemnification Procedure
                             -------------------------

5.1  Notice.  Promptly after receipt of notice that a Proceeding has commenced,
     ------
     the Indemnitee will, if a claim is to be made under this Agreement, notify
     the Company of that fact. The failure to notify the Company will not
     relieve it from any liability that it may have to the Indemnitee except to
     the extent of the Company's material damage resulting from such failure.

5.2  Company Participation.  The Company will be entitled to participate in any
     ---------------------
     Proceeding at its own expense and, except as otherwise provided below, to
     the extent that it may wish, the Company may assume the defense of any
     Proceeding for which indemnification is sought hereunder, with counsel
     reasonably satisfactory to the Indemnitee. After the Company notifies the
     Indemnitee of the Company's election to assume the defense of a

                                      -7-
<PAGE>

     Proceeding, during the Company's good faith active defense the Company will
     not be liable to the Indemnitee under this Agreement for any legal or other
     expenses subsequently incurred by the Indemnitee in connection with the
     defense of the Proceeding, other than reasonable costs of investigation or
     as otherwise provided below. The Indemnitee will have the right to employ
     the Indemnitee's counsel in any Proceeding, but the fees and expenses of
     the counsel incurred after the Company assumes the defense of the
     Proceeding will be at the expense of the Indemnitee, unless (a) the
     employment of counsel by the Indemnitee has been authorized by the Company,
     (b) the Indemnitee has reasonably concluded that there may be a conflict of
     interest between the Company and the Indemnitee in the conduct of the
     defense of a Proceeding, or (c) the Company has not in fact employed
     counsel to assume the defense of a Proceeding. In each of the foregoing
     cases the fees and expenses of the Indemnitee's counsel will be at the
     expense of the Company. The Company will not be entitled to assume the
     defense of any Proceeding brought by or on behalf of the Company or as to
     which the Indemnitee has made the conclusion that there may be a conflict
     of interest between the Company and the Indemnitee.

5.3  Settlement.  The Company will not settle or compromise any Proceeding in
     ----------
     any manner that would impose any penalty or limitation on the Indemnitee
     without the Indemnitee's consent. The Indemnitee will not settle or
     compromise any Proceeding without the Company's consent. Neither the
     Company nor the Indemnitee will unreasonably withhold their consent or
     approval under this Agreement.

5.4  Subrogation.  If the Company pays Indemnified Costs, the Company will be
     -----------
     subrogated to the extent of such payment to all of the rights of recovery
     of the Indemnitee against third parties. The Indemnitee will do all things
     reasonably necessary to secure such rights, including the execution of
     documents necessary to enable the Company effectively to bring suit to
     enforce such rights.

                         6.   Miscellaneous Provisions
                              ------------------------

6.1  Amendments; Waivers.  Amendments, waivers, consents and approvals under
     -------------------
     this Agreement must be in writing and designated as such. No failure or
     delay in exercising any right will be deemed a waiver of such right.

6.2  Integration.  This Agreement is the entire agreement between the parties
     -----------
     pertaining to its subject matter, and supersedes all prior agreements and
     understandings of the parties in connection with such subject matter.

6.3  Interpretation; Governing Law.  This Agreement is to be construed as a
     -----------------------------
     whole and in accordance with its fair meaning. This Agreement is to be
     interpreted in accordance with the laws of the State of Delaware relating
     to indemnification of Agents.

6.4  Headings.  Headings of Sections and subsections are for convenience only
     --------
     and are not a part of this Agreement.

                                      -8-
<PAGE>

6.5  Counterparts.  This Agreement may be signed in one or more counterparts,
     ------------
     all of which constitute one agreement.

6.6  Successors and Assigns.  This Agreement is binding upon and inures to the
     ----------------------
     benefit of each party and such party's respective heirs, personal
     representatives, successors and assigns. Nothing in this Agreement, express
     or implied, is intended to confer any rights or remedies upon any other
     person.

6.7  Expenses; Legal Fees.  Each party will pay its own expenses in the
     --------------------
     negotiation, preparation and performance of this Agreement. The prevailing
     party in any action relating to this Agreement will be entitled to
     reasonable legal fees, costs and expenses incurred in such action.

6.8  Representation by Counsel; Interpretation.  Each party acknowledges that it
     -----------------------------------------
     has been given an opportunity to be represented by counsel in connection
     with this Agreement. Any rule of law, including, but not limited to,
     Section 1654 of the California Civil Code, or any legal decision that would
     require interpretation of any claimed ambiguities in this Agreement against
     the party that drafted it, has no application and is expressly waived.

6.9  Specific Performance.  The Company acknowledges that in view of the
     --------------------
     uniqueness of the matters contemplated by this Agreement, the Indemnitee
     would not have an adequate remedy at law for money damages if this
     Agreement is not being performed in accordance with its terms. The Company
     therefore agrees that the Indemnitee will be entitled to specific
     enforcement of the terms hereof in addition to any other remedy to which
     the Indemnitee may be entitled.

6.10 Time is of the Essence.  Time is of the essence in the performance of each
     ----------------------
     provision of this Agreement.
