PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus.
It may not contain all the information that is important to you. We encourage
you to read this entire prospectus carefully.

The Company

We are a leading owner and operator of wireless communications and
broadcast transmission infrastructure. After giving effect to the completion of
the proposed transactions we describe in this prospectus, as of December 31,
1998, we owned or managed 6,105 towers, including 4,419 towers in the United
States and Puerto Rico and 1,686 towers in the United Kingdom. Our customers
currently include many of the world's major wireless communications and
broadcast companies, including Bell Atlantic Mobile, BellSouth Mobility, AT&T
Wireless, Nextel and the British Broadcasting Corporation.

Our strategy is to use our leading domestic and international position to
capture the growing consolidation and build-out opportunities created by:
. the outsourcing of towers by major wireless carriers;
. the need for existing wireless carriers to expand coverage and improve
capacity;
. the additional demand for towers created by new entrants into the
wireless communications industry;
. the privatization of state-run broadcast transmission networks; and
. the introduction of new digital broadcast transmission technology and
wireless technologies.

Our two main businesses are leasing antenna space on wireless and broadcast
multi-tenant towers and operating broadcast transmission networks. We also
provide complementary services to our customers, including network design,
radio frequency engineering, site acquisition, site development and
construction, antenna installation and network management and maintenance. We
believe that our end-to-end service capabilities are a key competitive
advantage in forming strategic partnerships to acquire large wireless and
broadcast tower portfolios and in winning tower construction mandates.

Our primary business in the United States is the leasing of antenna space
to wireless carriers under long-term contracts. After completion of the
proposed transactions we describe in this prospectus, we will have tower
clusters in 26 of the 50 largest U.S. metropolitan areas, 23 of which are east
of the Mississippi river. We believe that by owning and managing large tower
clusters we are able to offer our customers the ability to expand their
networks rapidly and efficiently across particular markets or regions. Our
acquisition strategy has been focused on adding tower clusters. For example, we
have entered into agreements with both Bell Atlantic Mobile, which we refer to
as BAM, and BellSouth Mobility, which we refer to as BellSouth, that will allow
us to control and operate substantially all the towers in their 850 MHz
networks in the eastern, southwestern and midwestern United States.

<PAGE>

operators in the United Kingdom on the towers we acquired from the BBC and from
various wireless carriers. After completion of the One2One transaction
described in this prospectus, we will have a nationwide wireless footprint in
the United Kingdom. We believe that our towers are uniquely situated in
locations that wireless carriers seeking to lease antenna space find
particularly desirable.

We believe our towers are attractive to a diverse range of wireless
communications industries, including PCS, cellular, ESMR, SMR, paging, and
fixed microwave, as well as radio and television broadcasting. In the United
States our major customers include AT&T Wireless, Aerial, BAM, BellSouth,
Motorola, Nextel, PageNet and Sprint PCS. In the United Kingdom our major
customers include the BBC, Cellnet, Dolphin, NTL, ONdigital, One2One, Orange,
Virgin Radio and Vodafone.

We have embarked on a major construction program for our customers to
enhance our tower footprint. In 1998, we constructed 231 towers at an aggregate
cost of approximately $46.0 million, and had begun construction of an
additional 72 towers as of December 31, 1998. In 1999, we plan to construct
between 800 and 1,100 towers at an estimated aggregate cost of between $150.0
million and $200.0 million for wireless carriers such as BAM, BellSouth and
Nextel. The actual number of towers built may be outside that range depending
on acquisition opportunities and potential build-to-suit contracts from large
wireless carriers. In addition, we were selected to build and operate in the
United Kingdom the world's first digital terrestrial television system.

Industry Overview

As the wireless communications industry has become more competitive,
wireless carriers have sought operating and capital efficiencies by outsourcing
network services and the build-out and operation of new and existing
infrastructure. These carriers have also begun co-locating transmission
equipment with other carriers on multiple tenant towers. We believe that there
has been a fundamental shift in strategy among established carriers relating to
infrastructure ownership. In order to concentrate on their customer bases and
expansion of their service offerings, many such carriers have begun to sell
their wireless communications infrastructure to, or establish joint ventures
with, experienced infrastructure providers that have the proven ability to
manage networks.

The television broadcasting industry is experiencing significant change
because of the impending widespread deployment of digital terrestrial
television broadcasting. Many countries are expected to start to establish
digital services within the next five years. The shift to digital transmission
will require network design, development and engineering services and the
significant enhancement of existing broadcast transmission infrastructure,
including new transmission and monitoring equipment and the modification,
strengthening and construction of towers. In addition, state-run broadcast
transmission networks are continuing to be privatized throughout the world.

We expect these trends to continue globally in both the wireless
communications and broadcasting industries. We believe that the next logical
step for wireless carriers and broadcasters will be the outsourcing of the
operation of their towers and transmission networks, including the transmission
of their signals, in much the same way as the BBC has done with its
transmission network. We believe that such carriers and broadcasters will only
entrust the operation of their towers and the transmission of their signals to
those infrastructure providers, such as us, that have the ability to manage
towers and transmission networks and a proven track record of providing end-to-
end services to the wireless communications and broadcasting industries.

<PAGE>

Growth Strategy

Our objective is to become the premier global provider of wireless
communications and broadcast transmission infrastructure and related services.
Our experience in expanding tower footprints and operating analog and digital
transmission networks, our significant relationships with wireless carriers and
broadcasters and our ability to offer customers our in-house technical and
operational expertise positions us to accomplish this objective. The key
elements of our growth strategy are to:

Maximize Utilization of Tower Capacity. We seek to increase the number of
antenna leases on the towers and rooftops that we own or manage. Many of our
towers have significant capacity for additional antennas. We can increase the
number of tenants on these towers at a low incremental cost.

Leverage Expertise of U.S. and U.K. Personnel to Capture Global Growth
Opportunities. Our ability to design, develop (build) and operate wireless
communications and broadcast transmission networks, including the transmission
of signals, is an important competitive advantage in our pursuit of growth
opportunities, as evidenced by the BBC, One2One, BAM, BellSouth and Powertel
transactions.

Partner with Wireless Carriers to Assume Ownership of their Existing
Towers. We will continue to seek to partner with major wireless carriers in
order to assume ownership of their towers directly or through joint ventures or
control their towers through contractual arrangements. We believe that we will
be able to capitalize on our relationships with our strategic partners and
customers with international operations to expand our global footprint.

Provide Build-to-Suit Towers for Wireless Carriers and Broadcasters. We
are aggressively pursuing build-to-suit opportunities. As wireless carriers
continue to expand and fill-in their service areas, they will require
additional communications sites and will have to build new towers where co-
location is not available. Similarly, the introduction of digital terrestrial
television broadcasting in the United States and elsewhere in the world will
require the construction of new broadcast towers to accommodate new digital
transmission equipment and analog transmission equipment displaced from
existing towers.

Acquire Existing Broadcast Transmission Networks. We intend to pursue
selective acquisitions of broadcast transmission networks and related
infrastructure around the world. We believe we can capitalize on the experience
we have gained through the acquisition of the BBC's broadcast transmission
network and our roll-out of digital television transmission services throughout
the United Kingdom.

Continue to Decentralize Management Functions. In order to better manage
our tower lease-up efforts and build-out programs, and in anticipation of the
continued growth of our tower footprint throughout the United States, we have
begun and plan to continue decentralizing some management and operational
functions. To that end, in addition to our Pittsburgh operating headquarters
and regional office, we have opened five regional offices and plan to add 10
additional regional offices in connection with the proposed transactions
described below.

Proposed Transactions

Proposed BAM JV

On December 8, 1998, we entered into an agreement, which we call the
Formation Agreement, with BAM to form a joint venture to own and operate
approximately 1,427 towers. These towers represent substantially all the towers
in BAM's 850 MHz wireless network in the eastern and

3
<PAGE>

southwestern United States and provide coverage of 11 of the top 50 U.S.
metropolitan areas, including New York, Philadelphia, Boston, Washington, D.C.
and Phoenix. A substantial majority of these towers are over 100 feet tall and
can accommodate multiple tenants.

Upon its formation, we will manage the day-to-day operations of the
proposed joint venture. Concurrently with the formation of the joint venture,
BAM and the joint venture will enter into a master build-to-suit agreement
pursuant to which the joint venture will build and own the next 500 towers to
be built for BAM's wireless communications business. The joint venture will
have the right to build an additional 200 towers for BAM thereafter. Pursuant
to a global lease agreement, BAM will lease antenna space on the towers
transferred to the joint venture, as well as the towers built pursuant to the
build-to-suit agreement.

Upon its formation, we will own approximately 62.3% of the joint venture
and BAM and certain of its affiliates will own the other 37.7% along with a
0.001% interest in the joint venture's operating subsidiary. To form the
proposed joint venture, we will contribute $250.0 million in cash and
approximately 15.6 million shares of our common stock (valued at $197.0
million) to the joint venture. BAM and its affiliates will transfer
approximately 1,427 towers along with related assets and liabilities to the
joint venture. The joint venture expects to borrow $180.0 million under a
committed $250.0 million revolving credit facility, following which the joint
venture will make a $380.0 million cash distribution to BAM. The joint venture
initially will have approximately $46.0 million of cash to fund its operations
and pay costs and expenses associated with building new towers.

Proposed BellSouth Transaction

On March 8, 1999, we entered into a preliminary agreement, which we call
the Letter Agreement, with BellSouth and certain of its affiliates to control
and operate approximately 1,850 towers. These towers represent substantially
all the towers in BellSouth's 850 MHz wireless network in the southeastern and
midwestern United States and provide coverage of 12 of the top 50 U.S.
metropolitan areas, including Miami, Atlanta, Tampa, Nashville and
Indianapolis. A substantial majority of these towers are over 100 feet tall and
can accommodate multiple tenants.

We will be responsible for managing, maintaining, marketing and leasing the
available space on BellSouth's towers. BellSouth will enter into a master
build-to-suit agreement with us pursuant to which we will have the right to
build, control and operate the next 500 towers to be built for BellSouth's
wireless communications business. BellSouth will lease antenna space on the
towers subject to the Letter Agreement, as well as the towers built pursuant to
the build-to-suit agreement.

The transaction is structured as a taxable sale pursuant to a master
sublease. While we will have complete responsibility for the towers and will
receive all the economic benefits of leasing available space on the towers,
BellSouth will continue to own the tower infrastructure. We will pay BellSouth
$610.0 million, consisting of $430.0 million in cash and approximately 9.1
million shares of our common stock (valued at $180.0 million), subject to
adjustment. While the transaction is expected to close in a series of closings
beginning in the second quarter of 1999, we will begin marketing all the towers
immediately. In connection with our entering into the Letter Agreement, we have
placed $50.0 million in an escrow account which will be returned to us at the
first closing date. See "Risk Factors--We May Not Consummate the Proposed
Transactions."

Proposed Powertel Acquisition

On March 15, 1999, we entered into an agreement, which we call the Asset
Purchase Agreement, with Powertel to purchase approximately 650 towers and
related assets. These towers represent substantially all of Powertel's owned
towers in its 1.9 GHz wireless network in the southeastern and midwestern
United States. Approximately 90% of these towers are clustered in

4
<PAGE>

seven southeastern states, providing coverage of such major metropolitan areas
as Atlanta, Birmingham, Jacksonville, Memphis and Louisville, and a number of
major connecting highway corridors in the southeast. These towers are
complementary to BellSouth's 850 MHz footprint in the southeast and have
minimal coverage overlap. Substantially all of these towers are over 100 feet
tall, were built within the last three years and can accommodate multiple
tenants.

Concurrently with the tower acquisition, we will enter into master lease
agreements pursuant to which Powertel will lease antenna space on the towers we
acquire in the acquisition.

We will purchase the 650 towers from Powertel for an aggregate cash
purchase price of $275.0 million. Pursuant to the Asset Purchase Agreement and
a related escrow agreement, we have placed $50.0 million in escrow to be
applied to the purchase price at closing. See "Risk Factors--We May Not
Consummate the Proposed Transactions".

Proposed One2One Transaction

On March 5, 1999, we entered into an agreement, which we call the Framework
Agreement, with One2One, pursuant to which our U.K. operating subsidiary, which
we call CTI, has agreed to manage, develop and, at its option, acquire up to
821 towers. These towers represent substantially all the towers in One2One's
1,800 MHz nationwide wireless network in the United Kingdom. We believe this
transaction will position us to capitalize on lease-up and build-out
opportunities provided by the introduction of new wireless technologies such as
UMTS.

CTI will be responsible for managing and leasing available space on the
towers, and will receive all the income from any such third party leases. The
term of the management arrangement will be for up to 25 years. During the
three-year period following the closing, CTI will have the right, at its
option, to acquire for (Pounds)1.00 per site One2One's interest in the 821
towers, to the extent such interests can be assigned. One2One has also agreed
to include as part of the Framework Agreement, including CTI's right to acquire
sites during the three-year period, any new One2One towers constructed during
the term of the agreement.

As consideration for this transaction, CTI has agreed to provide One2One
with free rent on the 821 towers for nine years, free rent on newly constructed
One2One towers assigned to CTI for 15 years and free rent on CTI towers on
which One2One currently leases space for two years.

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

Although we expect the Proposed BAM JV, the Proposed Powertel Acquisition
and the Proposed One2One Transaction to be consummated during the first half of
1999, and the first closing of the Proposed BellSouth Transaction to be
consummated by May 31, 1999, the operative agreements governing these
transactions are subject to a number of significant conditions. Therefore, we
cannot guarantee you that we will close any of these proposed transactions on
the terms described in this document or at all. See "Risk Factors--We May Not
Consummate the Proposed Transactions". When we refer to financial information
in this prospectus as "after giving effect to" or "pro forma for" the Proposed
Transactions, we mean after giving effect to the proposed transactions
described above, other than the Proposed One2One Transaction, which does not
have a material impact on our pro forma financial results.

Recent Transactions

On August 21, 1998, we increased our ownership interest in CTSH to 80.0% by
consummating a share exchange with the shareholders of CTSH. The remaining
20.0% of CTSH's shares are owned by a company called TeleDiffusion de France,
or TdF, whose ultimate parent is France Telecom. Immediately prior to the
exchange, we converted all shares of our then existing preferred stock into
shares of our common stock and reclassified our then existing common stock into
shares of our common stock. We refer to the exchange and the conversions
collectively as the Roll-Up. At that time, we also raised approximately $150.0
million in an initial public offering of our common stock. We have allocated
the net proceeds from our IPO to finance a portion of our investment in the
Proposed BAM JV.

On October 8, 1998, we acquired all the outstanding shares of Millennium
Communications Limited for aggregate consideration of $14.5 million, consisting
of cash, our common stock and the assumption of indebtedness. Millennium
develops, owns and operates telecommunications towers and related assets in the
United Kingdom. On the date of acquisition, Millennium owned 102 tower sites.
Millennium is being operated as a subsidiary of CTI.

On December 21, 1998, we privately placed 200,000 shares of our 12 3/4%
Senior Exchangeable Preferred Stock due 2010, with a liquidation preference of
$1,000 per share. We used a portion of the net proceeds of the exchangeable
preferred stock offering to repay substantially all of our then outstanding
indebtedness under our senior credit facility. We have allocated the remaining
net proceeds of the preferred stock offering to finance the balance of our
investment in the Proposed BAM JV.

On March 15, 1999, we entered into a loan agreement to finance our escrow
payments in connection with the Proposed BellSouth Transaction and the Proposed
Powertel Acquisition. We intend to use a portion of the net proceeds of the
offerings to repay all amounts outstanding under this loan agreement.

(a) CCIC expects that it will incur incremental operating expenses as a result
of the Proposed Transactions. Such incremental expenses are currently
estimated to amount to approximately $5.2 million per year for the Proposed
BAM JV and approximately $15.9 million per year for the Proposed BellSouth
Transaction and the Proposed Powertel Acquisition. The Company has included
the effect of these incremental expenses in the accompanying summary pro
forma financial data in order to more accurately present the effect of the
Proposed Transactions on CCIC's consolidated results of operations. The
effect of these incremental expenses has not been reflected in the
Unaudited Pro Forma Condensed Consolidated Statement of Operations included
elsewhere in this document. See "Notes to Unaudited Pro Forma Condensed
Consolidated Statement of Operations."
(b) Corporate development expenses represent costs incurred in connection with
acquisitions and development of new business initiatives. These expenses
consist primarily of allocated compensation, benefits and overhead costs
that are not directly related to the administration or management of
existing towers.
(c) Represents charges related to the issuance of stock options to certain
employees and executives.
(d) Represents the aggregate number of sites of CCIC, CTI, the Proposed BAM JV
and the Proposed Powertel Acquisition at the end of the period. As of
December 31, 1998, we had contracts with 1,365 buildings in the United
States to manage on behalf of such buildings the leasing of space for
antennas on the rooftops of such buildings. A revenue producing rooftop
represents a rooftop where we have arranged a lease of space on such
rooftop and, as such, are receiving payments in respect of our management
contract. We generally do not receive any payment for rooftops under
management unless we actually lease space on such rooftops to third
parties. As of December 31, 1998, we had 1,284 rooftop sites under
management throughout the United States that were not revenue producing
rooftops but were available for leasing to customers and, in the United
Kingdom, we had 54 revenue producing rooftop sites that were occupied by
our transmitters but were not available for leasing to customers.

(e) EBITDA is defined as operating income (loss) plus depreciation and
amortization and non-cash compensation charges. Adjusted EBITDA is defined
as the sum of (i) annualized site rental and broadcast transmission EBITDA
before corporate development for the most recent calendar quarter and (ii)
EBITDA, less site rental and broadcast transmission EBITDA before corporate
development, for the most recent four calendar quarters. EBITDA and
Adjusted EBITDA are presented as additional information because management
believes them to be useful indicators of our ability to meet debt service
and capital expenditure requirements. They are not, however, intended as
alternative measures of operating results or cash flow from operations (as
determined in accordance with generally accepted accounting principles).
Furthermore, our measure of EBITDA may not be comparable to similarly
titled measures of other companies.
(f) For purposes of computing the ratio of earnings to fixed charges, earnings
represent income (loss) before income taxes, minority interests and fixed
charges. Fixed charges consist of interest expense, the interest component
of operating leases and amortization of deferred financing costs. For the
year ended December 31, 1998, our earnings were insufficient to cover our
fixed charges by $125.3 million. For the year ended December 31, 1998,
earnings were insufficient to cover fixed charges of the Restricted Group
by $98.7 million.
(g) Total interest expense for the year ended December 31, 1998 includes
amortization of deferred financing costs and discount of $47.2 million for
CCIC, $0.9 million for CTI and $0.6 million for the Proposed BAM JV.
(h) Pro forma balances of cash and cash equivalents for the Restricted Group
exclude $248.1 million of proceeds from the IPO and the offering of
exchangeable preferred stock (along with interest earned on such amounts
since the consummation of these transactions) that will be contributed to
the Proposed BAM JV, of which approximately $45.9 million will remain in
the Proposed BAM JV after its formation.
(i) Net debt represents total debt less cash and cash equivalents.

forth below for each of the four years in the period ended December 31, 1998,
and as of December 31, 1995, 1996, 1997 and 1998, have been derived from the

consummated in 1997 and 1998. Results of operations of these acquired
businesses are included in the Company's consolidated financial statements for
the periods subsequent to the respective dates of acquisition. [D] The summary
historical financial and other data for the Restricted Group (as defined) are
not intended as alternative measures of operating results or cash flows from

(a) Corporate development expenses represent costs incurred in connection with
acquisitions and development of new business initiatives. These expenses
consist primarily of allocated compensation, benefits and overhead costs
that are not directly related to the administration or management of
existing towers. For the year ended December 31, 1997, such expenses
include (i) nonrecurring cash bonuses of $0.9 million paid to certain
executive officers in connection with the CTI Investment and (ii) a
nonrecurring cash charge of $1.3 million related to the purchase by CCIC of
shares of common stock from CCIC's former chief executive officer in
connection with the CTI Investment. See "Certain Relationships and Related
Transactions".
(b) Represents charges related to the issuance of stock options to certain
employees and executives.
(c) Includes a $1.2 million fee received in March 1997 as compensation for
leading the investment consortium which provided the equity financing for
CTI in connection with the CTI Investment.
(d) Represents the aggregate number of sites of CCIC as of the end of each
period.
(e) As of December 31, 1998, CCIC had contracts with 1,365 buildings in the
United States to manage on behalf of such buildings the leasing of space
for antennas on the rooftops of such buildings. A revenue producing rooftop
represents a rooftop where CCIC has arranged a lease of space on such
rooftop and, as such, is receiving payments in respect of its management
contract. CCIC generally does not receive any payment for rooftops under
management unless CCIC actually leases space on such rooftops to third
parties. As of December 31, 1998, CCIC had 1,284 rooftop sites under
management throughout the United States that were not revenue producing but
were available for leasing to customers and, in the United Kingdom, we had
54 revenue producing rooftop sites that were occupied by the Company's
transmitters but were not available for leasing to customers.
(f) EBITDA is defined as operating income (loss) plus depreciation and
amortization and non-cash compensation changes. EBITDA is presented as
additional information because management believes it to be a useful
indicator of CCIC's ability to meet debt service and capital expenditure
requirements. It is not, however, intended as an alternative measure of

19
<PAGE>

operating results or cash flow from operations (as determined in accordance
with generally accepted accounting principles). Furthermore, CCIC's measure
of EBITDA may not be comparable to similarly titled measures of other
companies.
(g) For purposes of computing the ratio of earnings to fixed charges, earnings
represent income (loss) before income taxes, fixed charges and equity in
earnings (losses) of unconsolidated affiliate. Fixed charges consist of
interest expense, the interest component of operating leases and
amortization of deferred financing costs. For the years ended December 31,
1995, 1996, 1997 and 1998, earnings were insufficient to cover fixed
charges by $21,000, $0.9 million, $10.8 million and $37.8 million,
respectively.
(h) The 1995, 1996 and 1997 amounts represent (1) the Senior Convertible
Preferred Stock privately placed by CCIC in August 1997 and October 1997,
all of which has been converted into shares of common stock, and (2) the
Series A convertible preferred stock, the Series B convertible preferred
stock and the Series C convertible preferred stock privately placed by CCIC
in April 1995, July 1996 and February 1997, respectively, all of which has
been converted into shares of common stock in connection with the
consummation of the IPO. The 1998 amount represents the 12 3/4%
exchangeable preferred stock.

RISK FACTORS

You should carefully consider the risks described below, as well as the
other information included in this prospectus, when evaluating an investment in
our [E] common stock [D] notes.

We May Not Be Able to Manage the Integration Necessitated by Our Rapid Growth

Our ability to implement our growth strategy depends, in part, on our
successes in integrating our acquisitions, investments, joint ventures and
strategic alliances into our operations. We have grown significantly over the
past two years through acquisitions and, as evidenced by the Proposed
Transactions, such growth continues to be an important part of our business
plan. The addition of approximately 4,748 towers to our tower footprints
through the Proposed Transactions will increase our current business
considerably and will add operating complexities. Successful integration of
these transactions will depend primarily on our ability to manage these
combined operations and to integrate new management with and into our existing
management. We cannot guarantee that we will be able to successfully integrate
these acquired businesses and assets or any future acquisitions into our
business or implement our plans without delay. If we fail to do so it could
have a material adverse effect on our financial condition and results of
operations.

We regularly evaluate potential acquisition and joint venture opportunities
and are currently evaluating potential transactions that could involve
substantial expenditures, possibly in the near term. Implementation of our
acquisition strategy may impose significant strains on our management,
operating systems and financial resources. If we fail to manage our growth or
encounter unexpected difficulties during expansion it could have a material
adverse effect on our financial condition and results of operations. The
pursuit and integration of acquisitions, investments, joint ventures and
strategic alliances will require substantial attention from our senior
management, which will limit the amount of time they are able to devote to our
existing operations. If we are successful in consummating future acquisitions,
we may have to incur substantial amounts of debt and contingent liabilities and
an increase in amortization expenses related to goodwill and other intangible
assets, all of which could have a material adverse effect on our financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources".

Our Substantial Level of Indebtedness Could Adversely Affect Our Financial
Condition

We are a highly leveraged company. The following chart sets forth certain
important credit information and is presented as of December 31, 1998, (1)
assuming we had completed the offerings and (2) assuming we had completed the
offerings and consummated the Proposed Transactions, each as of December 31,
1998.

<PAGE>

In addition, assuming we had completed the Proposed Transactions on January
1, 1998, for the twelve months ended December 31, 1998, our earnings would have
been insufficient to cover fixed charges by $104.2 million.

Given our substantial indebtedness, we could be affected in the following
ways:

. We could be more vulnerable to general adverse economic and industry
conditions.

. We may find it more difficult to obtain additional financing to fund
future working capital, capital expenditures and other general
corporate requirements.

. We will be required to dedicate a substantial portion of our cash flow
from operations to the payment of principal and interest on our debt,
reducing the available cash flow to fund other projects.

. We may have limited flexibility in planning for, or reacting to,
changes in our business and in the industry.

. We will have a competitive disadvantage relative to other less
leveraged companies in our industry.

Our ability to service our debt and to fund planned capital expenditures in
connection with our business strategy will depend, to a degree, on factors
beyond our control, including general economic, financial, competitive and
regulatory environments. We cannot guarantee that we will be able to generate
enough cash flow from operations or that we will be able to obtain enough
capital to service our debt or fund our planned capital expenditures. In
addition, we may need to refinance some or all of our indebtedness on or before
maturity. We cannot guarantee, however, that we will be able to refinance our
indebtedness on commercially reasonable terms or at all.

Currently we have debt instruments in place which restrict our ability to
incur more indebtedness, pay dividends, create liens, sell assets and engage in
certain mergers and acquisitions. Some of our subsidiaries, under the debt
instruments, are also required to maintain specific financial ratios. Our
ability to comply with the restrictions of these instruments and to satisfy our
debt obligations will depend on our future operating performance. If we fail to
comply with the debt restrictions, we will be in default under those
instruments, which in some cases would cause the maturity of substantially all
of our long-term indebtedness to be accelerated. See "Description of Certain
Indebtedness" and "Description of Capital Stock--Senior Exchangeable Preferred
Stock".

We May Not Consummate the Proposed Transactions

The debt and equity offerings are not conditioned on the consummation of
the Proposed BAM JV, the Proposed BellSouth Transaction, the Proposed Powertel
Acquisition or the Proposed One2One Transaction, and we cannot guarantee that
we will complete any or all of these transactions. While we have signed
definitive agreements with respect to the Proposed BAM JV, the Proposed
Powertel Acquisition and the Proposed One2One Transaction, and a preliminary
agreement in connection with the Proposed BellSouth Transaction, there are many
conditions that must be satisfied before we can close these transactions.

In addition, we cannot assure you that the transactions, if and when
consummated, will be done so on the terms described in this prospectus. The
Formation Agreement relating to the Proposed BAM JV, the Letter Agreement
related to the Proposed BellSouth Acquisition, the Asset Purchase Agreement
relating to the Proposed Powertel Acquisition and the Framework Agreement
relating to the Proposed One2One Transaction include provisions that could
result in our purchasing fewer towers at closing. If one or more of these
transactions is not consummated or is consummated on significantly different
terms than those described in this prospectus, it could substantially affect
the implementation of our business strategy.

22
<PAGE>

Moreover, if the Proposed BAM JV is not consummated, the net proceeds from
the preferred stock offering would not be used to form the joint venture, and
if the Proposed BellSouth Transaction or the Proposed Powertel Acquisition is
not consummated, part of the net proceeds from the debt and equity offerings
would not be used to consummate those transactions. Therefore, in either case,
we would have substantial discretion in applying the proceeds of our prior
exchangeable preferred stock offering and of the debt and equity offerings to
other uses. See "--We Will Have Broad Discretion in the Application of Proceeds
from the Offerings". Further, we cannot guarantee that we would be able to
identify any other acquisition of comparable value to our business or that any
other acquisition that we did pursue would be on substantially the same
economic terms as any of the proposed transactions we describe in this
prospectus.

In connection with our entering into the Asset Purchase Agreement with
Powertel, we made a $50.0 million escrow payment, which amount, or some portion
thereof, is subject to our forfeit if the Proposed Powertel Acquisition does
not close as a result of our inability or unwillingness to deliver the balance
of the purchase price at the scheduled closing date. In connection with our
entering into the Letter Agreement with BellSouth, we placed $50.0 million into
an escrow fund. We could be forced to pay this amount to BellSouth if we do not
enter into definitive agreements with respect to the Proposed BellSouth
Transaction, or if we fail to comply with all conditions, covenants and
representations we are required to fulfill in connection with the closings of
the Proposed BellSouth Transaction. The loss of these escrow payments, alone or
together, would significantly affect our available working capital and could
have a material adverse effect on our ability to effect our business strategy.
See "The Proposed Transactions".

We Require Significant Capital to Expand Our Operations and Make Acquisitions

Our business strategy contemplates substantial capital expenditures (1) in
connection with the expansion of our tower footprints by partnering with
wireless carriers to assume ownership or control of their existing towers, by
pursuing build-to-suit opportunities and by pursuing other tower acquisition
opportunities and (2) to acquire existing transmission networks globally as
opportunities arise. We anticipate that we will build, through the end of 1999,
approximately 750 towers in the United States at a cost of approximately $175.0
million and approximately 200 towers in the United Kingdom at a cost of
approximately $23.0 million. We also expect that the capital expenditure
requirements related to the roll-out of digital broadcast transmission in the
United Kingdom will be approximately (Pounds)100.0 million ($170.0 million). In
addition to capital expenditures in connection with contracted build-to-suits,
we expect to apply a significant amount of capital to finance the cash portion
of the consideration being paid in connection with the Proposed Transactions.

To fund the execution of the our business strategy, including the Proposed
Transactions, we expect to use the net proceeds of the offerings, the
borrowings available under CCI's senior credit facility, the borrowings
available under CTI's credit facility and the remaining net proceeds from our
IPO and our 12 3/4% exchangeable preferred stock offering. Following
consummation of the offerings and assuming all the Proposed Transactions are
consummated, we believe we will have sufficient liquidity to fund our
operations and pursue our business strategy in the near term. Our business
strategy, however, includes the pursuit of additional tower acquisition and
build-out opportunities, and we may have additional cash needs as opportunities
arise. Some of the opportunities that we are currently pursuing could require
significant additional capital. In the event we do not otherwise have cash
available, or borrowings under our credit facilities have otherwise been
utilized, when an opportunity arises, we would be forced to seek additional
debt or equity financing or to forego the opportunity. In the event we
determine to seek additional debt or equity financing, there can be no
assurance that any such financing will be available (on commercially acceptable
terms or at all) or permitted by the terms of our existing indebtedness. To the
extent we are unable to finance future capital expenditures, we will be unable
to achieve our currently contemplated business strategy. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources".

23
<PAGE>

We Will Have Broad Discretion in the Application of Proceeds from the Offerings

We will allocate a substantial portion of the estimated net proceeds from
the equity and debt offerings to fund the Proposed BellSouth Transaction and
the Proposed Powertel Acquisition and for general corporate purposes. In
addition, we may use these funds for as yet unidentified acquisitions,
investments or joint ventures in the United States or abroad, especially if any
or all of the Proposed Transactions are not consummated. If we do not
consummate any or all of the Proposed Transactions, we would have a significant
amount of unallocated net proceeds. Due to the number and variability of
factors that we will analyze before we determine how to use these net proceeds,
we cannot determine now how we would reallocate such proceeds. In addition, in
such case we would have broad discretion in allocating these net proceeds from
the offerings without any action or approval of our stockholders. Moreover, the
indenture governing the issuance of the notes will not contain any restrictions
on the use of proceeds from the offerings. Accordingly, investors will not have
the opportunity to evaluate the economic, financial and other relevant
information that will be considered by us in determining the application of any
such net proceeds. See "Use of Proceeds".

As a Holding Company, We Depend on Dividends from Subsidiaries to Meet Cash
Requirements or Pay Dividends

Crown Castle International Corp. is a holding company with no business
operations of its own. CCIC's only significant asset is the outstanding capital
stock of its subsidiaries. CCIC conducts all its business operations through
its subsidiaries. Accordingly, CCIC's only source of cash to pay dividends or
make other distributions on its capital stock or to pay interest on its
outstanding indebtedness is distributions with respect to its ownership
interest in its subsidiaries from the net earnings and cash flow generated by
such subsidiaries. Although the notes will not require cash interest payments
until , at such time the notes will have accreted to $ million and will
require annual cash interest payments of . In addition, the notes mature on
. In addition, we will be required to begin paying cash interest payments on
our 10 5/8% discount notes in May 2003 and on our 12 3/4% exchangeable
preferred stock in March 2004. CCIC currently expects that the earnings and
cash flow of its subsidiaries will be retained and used by such subsidiaries in
their operations, including to service their respective debt obligations. Even
if CCIC determined to pay a dividend on or make a distribution in respect of
the capital stock of its subsidiaries, there can be no assurance that CCIC's
subsidiaries will generate sufficient cash flow to pay such a dividend or
distribute such funds to CCIC or that applicable state law and contractual
restrictions, including negative covenants contained in the debt instruments of
such subsidiaries, would permit such dividends or distributions. Furthermore,
the terms of CCI's senior credit facility and its outstanding notes place
restrictions on CCI's ability, and the terms of CTI's credit facility and its
outstanding bonds place restrictions on CTI's ability, to pay dividends or to
make distributions, and in any event, such dividends or distributions may only
be paid if no default has occurred under the applicable instrument. In
addition, CCIC's subsidiaries will be permitted under the terms of their
existing debt instruments to incur additional indebtedness that may restrict or
prohibit the making of distributions, the payment of dividends or the making of
loans by such subsidiaries to CCIC. See "--Our Substantial Level of
Indebtedness Could Adversely Affect Our Financial Condition" and "Description
of Certain Indebtedness".

Our Agreements with TdF Give TdF Substantial Governance and Economic Rights

We have entered into agreements with TdF that give TdF significant
protective rights with respect to the governance of CCIC and CTI, the ownership
of CTI and the disposition of shares in CCIC and CTI. CTI's operations
currently account for a substantial majority of our revenues.

TdF's Governance Rights

We have granted TdF the ability to govern some of our activities, including
the ability to:

24
<PAGE>

. prohibit us from entering into certain material transactions, including
material acquisitions;

. elect up to two members of our Board of Directors; and

. elect at least one director to the executive and nominating and
corporate governance committees of our Board of Directors.

In addition, TdF has significant governance rights over CTI. Although TdF
currently has only a 20% equity interest in CTI, these governance rights give
TdF generally rights characteristic of those that a 50% partner to a joint
venture would have.

TdF's exercise of these rights could be contrary to your interests and
could prevent us from conducting some activities that our Board of Directors
consider to be in our best interests and the best interests of our
shareholders. See "Certain Relationships and Related Transactions--Agreements
with TdF Related to the Roll Up--Governance Agreement".

TdF's CTSH Option

Under the circumstances described below, TdF also will have the right to
acquire all of our shares in CTSH or to require us to purchase all of TdF's
shares in CTSH, at fair market value in either case. This right will be
triggered under the following circumstances:

. the sale of all or substantially all of our assets;

. a merger, consolidation or similar transaction that would result in any
person owning more than 50% of our voting power or equity securities;

. an unsolicited acquisition by any person of more than 25% of our voting
power or equity securities; or

. other circumstances arising from an acquisition by any person that
would give rise to a right of the BBC to terminate our analog or
digital transmission contracts with the BBC.

Further, immediately before any of these events occurs, TdF will have the
right to require us to purchase 50% of their Class A common stock in cash at
the same price we would have to pay once the event occurs.

If we were required to sell our shares in CTSH to TdF, we would no longer
own our U.K. business. On the other hand, if we were required to purchase all
of TdF's shares in CTSH and/or purchase 50% of their Class A common stock, we
cannot guarantee that we would have the necessary funds to do so or that we
would be permitted to do so under our debt instruments. If we did not have
sufficient funds, we would have to seek additional financing. We cannot
guarantee, however, that such financing would be available on commercially
reasonable terms or at all. If such financing were not available, we might be
forced to sell certain other assets at unfavorable prices in order to generate
the cash needed to buy the shares from TdF. In addition, our obligation to
purchase TdF's shares could result in an event of default under our debt
instruments.

TdF's Liquidity Rights

Under certain other circumstances, TdF will have the right to require us to
purchase all of their shares in CTSH, at fair market value. We may elect to pay
either (1) in cash or (2) with our common stock at a discount of 15% to its
market value. We cannot guarantee that we will have sufficient funds to
purchase such shares for cash if TdF were to require us to purchase their
shares of capital stock of CTSH. If we did not have sufficient funds, we would
either need to seek additional financing or purchase the shares with our common
stock. We cannot guarantee that we could obtain such financing on terms
acceptable to us. If we were to issue shares of common stock to effect the

25
<PAGE>

purchase, this would result in substantial dilution of our other stockholders,
could adversely affect the market prices of the common stock and could impair
our ability to raise additional capital through the sale of our equity
securities. [E] See "--This Offering will Result in Substantial Dilution to the
Value of Our Common Stock".

TdF's Preemptive Rights

The Construction and Acquisition of Towers Involves Various Risks

Our growth strategy depends on our ability to construct, acquire and
operate towers in conjunction with the expansion of wireless carriers. As of
December 31, 1998, we had 72 towers under construction. We currently have plans
to commence construction on approximately 800 to 1,100 additional towers during
fiscal 1999. Our ability to construct new towers can be affected by a number of
factors beyond our control, including:

. zoning and local permitting requirements and national regulatory
approvals;

. availability of construction equipment and skilled construction
personnel; and

. bad weather conditions.

In addition, as the concern over tower proliferation has grown in recent
years, certain communities have placed restrictions on new tower construction
or have delayed granting permits required for construction. You should consider
that:

. the barriers to new construction may prevent us from building towers
where we want;

. we may not be able to complete the number of towers planned for
construction in accordance with the requirements of our customers; and

. we cannot guarantee that there will be a significant need for the
construction of new towers once the wireless carriers complete the
build-out of their tower network infrastructure.

Competition for the acquisition of towers is keen, and we expect it to
continue to grow. We not only compete against other independent tower owners
and operators, but also against wireless carriers, broadcasters and site
developers. As competition increases for tower acquisitions, we may be faced
with fewer acquisition opportunities, as well as higher acquisition prices.
While we regularly explore acquisition opportunities, we cannot guarantee that
we will be able to identify suitable towers to acquire in the future. In
addition, we may need to seek additional debt or equity financing in order to
fund such acquisitions and for working capital to fund the construction of the
towers we have already planned or have under contract. We cannot, however,
guarantee that such financing will be available or that the proposed financings
will be permitted under our debt instruments. Moreover, we cannot guarantee
that we will be able to identify, finance and complete future construction and
acquisitions on acceptable terms or that we will be able to manage profitably
and market under-utilized capacity on additional towers. The extent to which we
are unable to construct or acquire additional towers, or manage profitably
tower expansion, may have a material adverse effect on our financial condition
and results of operations.

26
<PAGE>

We believe that the time frame for the current wireless build-out cycle may
be limited to the next few years, as many PCS and PCN networks have already
been built out in large markets. If we do not move quickly and aggressively to
obtain growth capital and capture this infrastructure opportunity, our
financial condition and results of operations could be materially adversely
affected.

Our Business Depends on the Demand for Wireless Communications

Demand for our site rentals depends on demand for communication sites from
wireless carriers, which, in turn, depends on the demand for wireless services.
Most types of wireless services currently require ground-based network
facilities, including communication sites for transmission and reception. The
demand for our sites depends on certain factors which we cannot control,
including:

. the level of demand for wireless services generally;

. the financial condition and access to capital of wireless carriers;

. the strategy of carriers with respect to owning or leasing
communication sites;

. changes in telecommunications regulations; and

.general economic conditions.

The wireless communications industry has experienced significant growth in
recent years. A slowdown in the growth of, or reduction in, demand in a
particular wireless segment could adversely affect the demand for communication
sites. For example, we anticipate that a significant amount of our revenues
over the next several years will be generated from carriers in the PCS and PCN
market and, as such, we will be subject to downturns in PCS and PCN demand.
Moreover, wireless carriers often operate with substantial leverage, and
financial problems for our customers could result in accounts receivable going
uncollected, in the loss of a customer and the associated lease revenue or in a
reduced ability of these customers to finance expansion activities.

Finally, advances in technology, such as the development of new satellite
systems, could reduce the need for land-based transmission and reception
networks. The occurrence of any of these factors could have a material adverse
effect on our financial condition and results of operations.

Variability in Demand for Network Services May Reduce the Predictability of Our
Results

Demand for our network services fluctuates from period to period and within
periods. These fluctuations are caused by a number of factors, including:

. the timing of customers' capital expenditures;

. annual budgetary considerations of customers;

. the rate and volume of wireless carriers' tower build-outs;

. timing of existing customer contracts; and

. general economic conditions.

While demand for our network services fluctuates, we must incur certain
costs, such as maintaining a staff of network services employees in
anticipation of future contracts, even when there may be no current business.
Consequently, the operating results of our network services businesses for any
particular period may vary significantly, and should not be considered as
necessarily being indicative of longer-term results. Furthermore, as wireless
carriers complete their build-outs, the need for the construction of new towers
and the demand for certain network services could decrease significantly and
could result in fluctuations and, possibly, significant declines in our
operating performance.

27
<PAGE>

We Operate our Business in an Increasingly Competitive Industry--Many of Our
Competitors Have Significantly More Resources

We face competition for site rental customers from various sources,
including:

. other large independent tower owners;

. wireless carriers that own and operate their own tower footprints and
lease antenna space to other carriers;

. site development companies which acquire antenna space on existing
towers for wireless carriers and manage new tower construction; and

. traditional local independent tower operators.

Wireless communications carriers that own and operate their own tower
footprints generally are substantially larger and have greater financial
resources than we have. We believe that tower location and capacity, price,
quality of service and density within a geographic market historically have
been and will continue to be the most significant competitive factors affecting
the site rental business.

We compete for acquisition and new tower construction opportunities with
wireless communications carriers, broadcasters, site developers and other
independent tower operators. We believe that competition for tower acquisitions
will increase and that additional competitors will enter the tower market.
These additional competitors may have greater financial resources than we have.
See "--The Construction and Acquisition of Towers Involves Various Risks".

NTL, which owns the privatized engineering division of the Independent
Broadcasting Authority, is our principal competitor in the terrestrial
broadcast transmission market in the United Kingdom. We could encounter
significant competition from NTL for our transmission business with the BBC or
ONdigital following the expiration of our current contracts with these
broadcasters. See "--We Rely Heavily on Agreements with Several Business
Partners".

We Rely Heavily on Agreements with Several Business Partners

Assuming we had completed the Roll-Up and the Proposed Transactions as of
January 1, 1998, none of our customers would have accounted for more than ten
percent of our revenues except the BBC, which would have accounted for
approximately 25.1% of our revenues for the twelve month period ended December
31, 1998.

Our broadcast transmission business is substantially dependent on contracts
with the BBC. See "Business--U.K. Operations--Significant Contracts". The
initial term of our analog transmission contract with the BBC will expire on
March 31, 2007, and our digital transmission contract with the BBC expires on
October 31, 2010. In addition, our digital transmission contract with the BBC
may be terminated by the BBC after five years if the BBC's board of governors
does not believe that digital television in the United Kingdom has enough
viewers, subject to payment to CTI of predetermined cash compensation if this
occurs. We cannot guarantee that the BBC will renew these contracts or that
they will not attempt to negotiate terms that are not as favorable to us as
those in place now. If we were to lose the BBC contracts, our business, results
of operations and financial condition would be materially adversely affected.

In order to optimize service coverage in the United Kingdom and enable
viewers to receive all analog UHF television services using one receiving
antenna, CTI and NTL have agreed to share all UHF television sites. See
"Business--U.K. Operations--Significant Contracts". We are currently in
negotiations with NTL to amend the agreement to reflect the build-out of
digital transmission sites and equipment, new rates for site sharing fees for
new digital facilities and revised operating and

28

maintenance procedures for the new equipment. This agreement may be terminated
with five years' notice by either CTI or NTL, and is set to expire on December
31, 2005. Although we do not believe that the agreement will be terminated, we
cannot guarantee that it will not be, which could have a material adverse
effect on our business, results of operations and financial condition.

We Are Subject to Extensive Regulations Which Could Change at Any Time

We are subject to a variety of foreign, federal, state and local
regulation. In the United States, both the Federal Communications Commission
and Federal Aviation Administration regulate towers and other sites used for
wireless communications transmitters and receivers. Such regulations control
siting and marking of towers and may, depending on the characteristics of the
tower, require registration of tower facilities. Most proposals to construct
new antenna structures or to modify existing antenna structures are reviewed by
both the FCC and the FAA to ensure that a structure will not present a hazard
to aviation. We generally indemnify our customers against any failure to comply
with applicable standards. Failure to comply with applicable requirements may
lead to civil penalties or require us to assume costly indemnification
obligations. Local regulations include city or other local ordinances, zoning
restrictions and restrictive covenants imposed by community developers. These
regulations vary greatly but typically require tower owners to obtain approval
from local officials or community standards organizations prior to tower
construction. Local regulations can delay or prevent new tower construction or
site upgrade projects, thereby limiting our ability to respond to customers'
demands. In addition, such regulations increase the costs associated with new
tower construction. We cannot guarantee that existing regulatory policies will
not adversely affect the timing or cost of new tower construction or that
additional regulations will not be adopted which increase such delays or result
in additional costs. These factors could have a material adverse effect on our
financial condition and results of operations.

In the United Kingdom, both OFTEL and the Radiocommunications Agency
regulate and monitor telecommunications and frequency licensing for sites used
for wireless communications transmitters and receivers. Site rental fees for
broadcasting (but not telecommunications) are also subject to price regulation
by OFTEL. In order to construct or materially alter towers, we must receive
regulatory approvals from the Civil Aviation Authority, which ensures that new
antenna structures do not present a hazard to aviation, and from local
government planning authorities. In addition, we sometimes must receive
international frequency clearance. Our ability to respond to customers' demands
may be delayed or even prevented by the need to seek these approvals. We cannot
guarantee, therefore, that existing regulatory policies will not adversely
affect the timing or cost of new tower construction or that additional
regulations will not be adopted which increase such delays or result in
additional costs. These factors could have a material adverse effect on our
financial condition and results of operations.

Since we signed the analog transmission contract with the BBC, the BBC has
increased its service requirements to include 24-hour broadcasting on our
terrestrial transmission network for the BBC's two national television services
and a requirement for CTI to add a number of filler stations to its network to
extend existing BBC services. The BBC has agreed to increases of approximately
(Pounds)800,000 ($1,330,240) per year in the charges payable by the BBC to CTI
for these service enhancements. The additional charges may necessitate an
amendment to CTI's Transmission Telecommunications License. OFTEL, the relevant
regulatory authority in the United Kingdom, has confirmed in initial
discussions with CTI that it is not OFTEL's intention to prevent the provision
of such additional services to the BBC at an additional charge. CTI is
discussing with OFTEL the most appropriate way to rectify this situation in
order to allow the additional services to be provided to the BBC in return for
the additional agreed payments. While we expect the license to be amended,
there can be no assurance as to the final resolution of these issues with
OFTEL.

<PAGE>

Our customers may also become subject to new regulations or regulatory
policies which adversely affect the demand for communication sites. In
addition, as we pursue international opportunities, we will be subject to
regulation in foreign jurisdictions.

We are also subject to laws and regulations relating to worker health and
safety. If we fail to comply with such laws and regulations, it could have a
material adverse effect on our business, results of operations or financial
condition.

Costs of Compliance with Environmental Laws Could Adversely Affect Our
Financial Condition

Our operations are subject to foreign, federal, state and local laws and
regulations regarding the management, use, storage, disposal, emission, release
and remediation of, and exposure to, hazardous and nonhazardous substances,
materials or wastes. Under certain environmental laws, we could be held liable
for the remediation of hazardous substance contamination at current or former
facilities or at third-party waste disposal sites, and we also could be subject
to personal injury or property damage claims related to such contamination.
Although we believe that we are in substantial compliance with all applicable
environmental laws, we cannot guarantee that costs of compliance with existing
or future environmental laws will not have a material adverse effect on our
financial condition and results of operations. See "Business--Environmental
Matters".

Emissions from Our Antennas May Create Health Risks

Our towers are subject to government requirements and other guidelines
relating to radio frequency emissions. The potential connection between radio
frequency emissions and certain negative health effects, including some forms
of cancer, has been the subject of substantial study by the scientific
community in recent years. To date, the results of these studies have been
inconclusive. Although we have not been subject to any claims relating to radio
frequency emissions, we cannot guarantee that we will not be subject to such
claims in the future.

We Are Subject to Risks Associated with Our International Operations

We conduct business in countries outside the United States, which exposes
us to fluctuations in foreign currency exchange rates. For the twelve month
period ended December 31, 1998, assuming we had completed the Roll-Up on
January 1, 1998, but without giving effect to the Proposed Transactions,
approximately 74.3% of our consolidated revenues would have originated outside
the United States, all of which were denominated in currencies other than U.S.
dollars (principally pounds sterling). We have not historically engaged in
significant hedging activities with respect to our non-U.S. dollar operations.

Our international operations are subject to other risks, such as the
imposition of government controls, inflation, tariff or taxes and other trade
barriers, difficulties in staffing and managing international operations,
price, wage and exchange controls, and political, social and economic
instability. We cannot guarantee that these and other factors will not have a
material adverse effect on our financial condition or results of operations.

We Are Heavily Dependent on Our Senior Management

Our existing operations and continued future development are dependent to a
significant extent upon the performance and active participation of certain key
individuals, including senior management. We cannot guarantee that we will be
successful in retaining the services of these, or other key personnel. None of
our employees have signed noncompetition agreements. If we were to lose any of
these individuals, our financial condition and results of operations could be
materially adversely affected.

[D] The Notes Are Subject to the Risk of Fraudulent Conveyance Liability

Various laws enacted for the protection of creditors may apply to our
incurrence of indebtedness, including the issuance of the notes in this
offering. If a court were to find in a lawsuit by an unpaid creditor or
representative of creditors that we did not receive fair consideration or
reasonably equivalent value for incurring such indebtedness or obligation and,
at the time of such incurrence, we (1) were insolvent; (2) were rendered
insolvent by reason of such incurrence; (3) were engaged in a business or
transaction for which our remaining assets constituted unreasonably small
capital; or (4) intended to incur or believe we would incur obligations beyond
our ability to pay such obligations as they mature, such court, subject to
applicable statutes of limitation, could determine to invalidate, in whole or
in part, such indebtedness and obligations as fraudulent conveyances or
subordinate such indebtedness and obligations to existing or future creditors.

[D] Original Issue Discount Will Accrue on the Notes and Create a Tax Liability
for Noteholders

The notes will be issued at a substantial discount from their stated
principal amount at maturity. Consequently, although cash interest on the notes
generally will not be payable prior to , 2004, original issue discount
will be includable in the gross income of a holder of the notes for U.S.
federal income tax purposes in advance of the receipt of such cash payments on
the notes. See "Certain United States Federal Income Tax Considerations" for a
more detailed discussion on the U.S. federal income tax consequences of
purchase, ownership and disposition of the notes.

If a bankruptcy case is commenced by or against us under the U.S.
Bankruptcy Code after the issuance of the notes, the claim of a holder of notes
with respect to the principal amount thereof may be limited to an amount equal
to the sum of (1) the initial offering price and (2) that portion of the
original issue discount that is not deemed to constitute "unmatured interest"
for purposes of the U.S. Bankruptcy Code. Any OID that was not accrued as of
any such bankruptcy filing would constitute "unmatured interest."

If the notes provide initial holders with a yield to maturity which equals
or exceeds the Treasury-based interest rate in effect for the month of their
issuance plus five percentage points, then we will not be able to deduct
original issue discount with respect to the notes until paid. In the event that
such yield to maturity exceeds such interest rate plus six percentage points,
then we may not be able to deduct a portion of such original issue discount.
See "Certain United States Federal Income Tax Considerations--U.S. Holders--
Applicable High Yield Discount Obligations".

[E] Risk of Loss of Tax Benefits and Restrictions on Stock Transfer

If, as a result of any transaction involving our equity securities, an
ownership change occurs for federal income tax purposes, our ability to use our
net operating losses, which we refer to as NOLs, to offset taxable income, and
thereby reduce our tax liability, would be severely limited. Under Section 382
of the Internal Revenue Code of 1986, as amended, an ownership change would be
deemed to have occurred if on any testing date the ownership of stock by one or
more 5-percent shareholders had increased by more than 50 percentage points
during the preceding three years. The need to preserve our NOLs by complying
with the limitations imposed by Section 382 may limit our ability to raise
equity financing in the future.

The common stock sold in this offering will be deemed, for purposes of
Section 382, to have been acquired by a separate public group treated as a new
5-percent shareholder which had an increase in ownership. The ownership
increase by this new public group, as well as any ownership increase by other
5-percent shareholders, must be taken into account in determining whether we
have undergone an ownership change under Section 382.

31
<PAGE>

It is unclear whether the offering will result in an ownership change.
However, we have taken and must continue to take into account the public group
ownership increase resulting from the common stock sold in the offering for
three years after the sale in computing the change in ownership for future
transactions (including the issuance of additional common stock or equity-
related instruments).

We are Subject to Year 2000 Compliance Problems

We are in the process of conducting a comprehensive review of our computer
systems to identify which of our systems will need to be modified, upgraded or
converted to recognize dates after December 31, 1999, which is known as the
year 2000 problem. The failure to correct a material year 2000 problem could
result in a system failure, such as the failure of tower lighting or security
monitoring systems, or miscalculations causing disruption of operations
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

In 1997 we established a year 2000 project to ensure that the issue
received appropriate priority and that the necessary resources were made
available. This project includes the replacement of our worldwide business
computer systems with systems that use programs that will make approximately
90% of our business computer systems year 2000 compliant. The testing phase of
the year 2000 project is ongoing as hardware or system software is remediated,
upgraded or replaced. Testing as well as remediation is scheduled for
completion in June 1999. The final phase of our year 2000 project, contingency
planning, will be completed and tested to the extent possible by September
1999.

However, we cannot assure you that all year 2000 compliance issues will be
resolved without any future disruption or that we will not incur significant
additional expense. In addition, if some of our major suppliers and customers
fail to address their own year 2000 compliance issues, their non-compliance
could have a material adverse effect on us and our operations.

[E] Anti-Takeover Provisions in Our Certificate of Incorporation Could Have
Effects That Conflict with the Interests of Our Stockholders

Certain provisions of our certificate of incorporation, by-laws and
operative agreements entered into in connection with the Roll-Up could make it
more difficult for a third party to acquire control of us even if such change
in control would be beneficial to our stockholders. These provisions include:

. the right of the holders of our Class A common stock to elect up to two
members of the Board of Directors;

. a staggered Board of Directors;

. the authority of the Board of Directors to issue preferred stock
without approval of the holders of common stock (other than the holders
of our Class A common stock);

. the establishment of advance notice requirements for director
nominations and actions to be taken at annual meetings; and

. the requirement that the holders of our Class A common stock approve
certain changes to the certificate of incorporation or the by-laws.

In addition, our by-laws permit special meetings of the stockholders to be
called only upon the request of a majority of the Board of Directors, and deny
stockholders the ability to call such meetings. Pursuant to the governance
agreement with TdF, TdF generally will have the right to purchase our equity
interest in CTSH upon the occurrence of an acquisition of us that is not
approved by TdF. In addition, subject to certain limitations, our BBC contracts
may be terminated

32
<PAGE>

upon the occurrence of certain change of control events (as defined in such
contracts). Such provisions, as well as the provisions of Section 203 of the
Delaware General Corporation Law (to which we are subject), could impede a
merger, consolidation, takeover or other business combination or discourage a
potential acquirer from making a tender offer or otherwise attempting to obtain
control of us. In certain circumstances, the fact that corporate devices are in
place that will hinder takeover attempts could reduce the market value of our
common stock. See "--Our agreements with TdF Give TdF Substantial Governance
and Economic Rights" and "Description of Capital Stock".

[E] Sales of a Substantial Number of Shares of Common Stock After the Equity
Offering Could Adversely Affect the Market Price of the Common Stock

Upon completion of the equity offering, we will have shares of common
stock outstanding. In addition, we have reserved for issuance shares of
common stock upon exercise of outstanding stock options, shares of common
stock upon exercise of outstanding warrants and shares of common stock for
the conversion of the outstanding Class A common stock. The shares sold in
the offering will be freely transferable without restriction under the
Securities Act, unless they are held by our "affiliates" as that term is used
under the Securities Act. See "Shares Eligible for Future Sale".

[E] This Offering Will Result in Substantial Dilution to the Value of Our
Common Stock

Persons purchasing shares of common stock in the equity offering will incur
immediate and substantial dilution in net tangible book value per share.
Purchasers of shares in the equity offering will experience dilution of $ per
share. In addition, until the second anniversary of the closing of the Roll-Up,
TdF has the right, and in certain circumstances the Company can require TdF, to
exchange its CTSH shares and warrants for CTSH shares for shares of our Class A
common stock (which is convertible into our common stock) and warrants for our
Class A common stock (which is convertible into our common stock). Such
exchange would be based on the exchange ratio used in the Roll-Up and, as a
result, could result in substantial additional dilution. Furthermore, following
the second anniversary of the Roll-Up, unless TdF shall have previously
exchanged its shares of capital stock of CTSH in accordance with the Governance
Agreement, TdF can require us to purchase all of TdF's equity interest in CTSH
at its fair market value, which purchase may be made, at our election, in
shares of common stock valued at a discount of 15% to its then current market
value. See "--Our Agreements with TdF Give TdF Substantial Governance and
Economic Rights". If we were to make such an election, it would result in
substantial additional dilution. See "--Our Agreements with TdF Give TdF
Substantial Governance and Economic Rights" and "Dilution". In addition, to the
extent that outstanding options and warrants to purchase common stock are
exercised, there could be substantial additional dilution.

Except in certain circumstances, if we issue any equity securities (other
than equity that is mandatorily exchangeable for debt, such as the exchangeable
preferred stock) to any person, including the equity offering and in connection
with the Proposed BAM JV and the Proposed BellSouth Transaction, we must offer
TdF the right to purchase, at the same cash price and on the same other terms
proposed, up to the amount of such equity securities as would be necessary for
TdF and its affiliates to maintain their consolidated ownership interest in us.
TdF will be able to exercise such preemptive rights in connection with our
acquisition of Millennium Communications Limited in the United Kingdom on
October 8, 1998 and in connection with our contribution of shares of our common
stock to the Proposed BAM JV and our payment of consideration in connection
with the Proposed BellSouth Transaction. If TdF exercises its preemptive
rights, it will be able to acquire up to 125,000 shares of our common stock at
a price of $13.00 per share as a result of the Millennium acquisition, up to
5.42 million shares at a price of $12.65 per share in connection with the
closing of the Proposed BAM JV. TdF will also have preemptive rights in
connection with the closing of the Proposed BellSouth Transaction.

[E] Fluctuations in Business Activity May Result in Volatility of Share Price

The market price of the common stock after the equity offering may be
significantly affected by factors such as quarterly variations in our results
of operations, the announcement of new contracts by us or our competitors,
technological innovation by us or our competitors and general market conditions
specific to particular industries. Such fluctuations may adversely affect the
market price of the common stock.

[D] There is Currently No Market for the Notes

The notes are a new issue of securities for which there is currently no
trading market. The underwriters have advised us that they intend to make a
market in the notes, although the underwriters are not obligated to do so and
may discontinue such market making at any time. We do not intend to apply for
listing of the notes on any domestic securities exchange or to seek approval
for quotation through an automated quotation system. Accordingly, there can be
no assurance that an active market will develop upon completion of the debt
offering or, if developed, that such market will be sustained or as to the
liquidity of any market.

USE OF PROCEEDS

[D] The net proceeds from the debt offering are estimated to be $
million, after deducting estimated fees and expenses. Concurrently with the
debt offering, we are offering shares of our common stock. The closing of
the debt offering is conditioned upon the closing of the equity offering.

[E] The net proceeds from the equity offering are estimated to be
approximately $ million, after deducting estimated fees and expenses.
Concurrently with the equity offering, we are offering $ million principal
amount at maturity of our % Senior Discount Notes due 2011. The closing of
the equity offering is conditioned upon the closing of the debt offering.

We expect to use the total net proceeds of the debt and equity offerings,
which are estimated to be $ million, to repay a term loan facility incurred
to finance a portion of the Proposed BellSouth Transaction and the Proposed
Powertel Acquisition, to finance the balance of the Proposed BellSouth
Transaction and the Proposed Powertel Acquisition and for general corporate
purposes. The loans we are repaying under the term loan facility were used to
refinance indebtedness under CCI's senior credit facility. The term loans
mature on November 30, 2007 and bear interest at an increasing rate on LIBOR,
not to exceed 16.0%.

However, the closing of the offerings is not contingent on the consummation
of any of the Proposed Transactions. The Proposed Transactions may not occur or
may occur on terms significantly different from those described in this
prospectus. If the Proposed BellSouth Transaction or Proposed Powertel
Acquisition does not occur, or if either or both occurs on terms different from
those described, we would be able to use the net proceeds from the offerings
that were allocated to finance the Proposed BellSouth Transaction and Proposed
Powertel Acquisition for working capital and general corporate purposes,
including to finance as yet unidentified acquisitions, investments or joint
ventures in the United States or abroad. In that situation, we would have broad
discretion in allocating a significant portion of the net proceeds from the
offerings without action or approval of [D] the holders of the discount notes
[E] the holders of our common stock. Accordingly, if the Proposed BellSouth
Transaction or the Proposed Powertel Acquisition is not consummated as
described in this prospectus, holders of our [D] discount notes [E] common
stock would not have the opportunity to evaluate the economic, financial and
other relevant information that we would consider in determining the
application of the net proceeds of the offerings.

[E] PRICE RANGE OF COMMON STOCK

Our common stock is listed and traded on the Nasdaq National Market under
the symbol "TWRS". The following table sets forth for the periods indicated the
high and low sale prices of the common stock as reported by Nasdaq:

<TABLE>
<CAPTION>
High Low
------ ------
<S> <C> <C>
1998
Third Quarter............................................ $13.31 $ 6.00
Fourth Quarter........................................... 23.50 9.87
1999
First Quarter (through March 15, 1999)................... $23.50 $16.63
</TABLE>

On March 15, 1999, the last reported sale price of the common stock as
reported by Nasdaq was $19.94. As of March 15, 1999, there were approximately
256 holders of record of the common stock.

[E] DIVIDEND POLICY

We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying cash dividends on our capital stock in the foreseeable
future. It is our current policy to retain earnings to finance the expansion of
our operations. Future declaration and payment of dividends, if any, will be
determined in light of the then-current conditions, including our earnings,
operations, capital requirements, financial condition and other factors deemed
relevant by the Board of Directors. In addition, our ability to pay dividends
is limited by the terms of our debt instruments and the terms of the
certificate of designations in respect of our 12 3/4% exchangeable preferred
stock. See "Description of Certain Indebtedness" and "Description of Capital
Stock".

[E] DILUTION

Dilution is the amount by which the offering price paid by the purchasers
of the common stock offered hereby will exceed the net tangible book value per
share of common stock after the offerings. Net tangible book value per share is
determined at any date by subtracting the total liabilities and minority
interests of the company from the total book value of the tangible assets of
the company and dividing the difference by the number of shares of common stock
deemed to be outstanding (including shares issuable upon conversion of
outstanding shares of Class A common stock) at such date.

Our net tangible book value on December 31, 1998, after subtracting the
interests of the preferred shareholders, was approximately $ or $ per
share. After giving effect to the receipt of approximately $ million of
estimated net proceeds from the sale by us of shares of common stock
pursuant to the offering, our pro forma net tangible book value at December 31,
1998 would have been approximately $ million or $ per share. This
represents an immediate increase in pro forma net tangible book value of $
per share to the existing stockholders and an immediate dilution of $ per
share to new investors purchasing shares of common stock in the offering. The
following table illustrates the substantial and immediate per share dilution to
new investors:

<TABLE>
<CAPTION>
Per Share

<S> <C>

(a) Before deducting underwriting discounts and estimated transaction
fees and expenses of $ million to be paid by us in connection
with the offering.
(b) Dilution is determined by subtracting net tangible book value per
share after the offering from the amount assumed paid by a new
investor per share of common stock.

All of the foregoing computations include the 11,340,000 shares of Class A
common stock owned by DFI, which are convertible into an aggregate of
11,340,000 shares of common stock. See "Certain Relationships and Related
Transactions--Agreements with TdF Related to the Roll-Up". The foregoing tables
and discussion assume no exercise of stock options or warrants after December
31, 1998 and exclude (i) shares issuable upon exercise of stock options
outstanding as of December 31, 1998 having a weighted average exercise price of
$ per share under our 1995 Stock Option Plan, (ii) additional shares
authorized for issuance under our 1995 Stock Option Plan, (iii) warrants to
purchase 1,314,990 shares of common stock at an exercise price of $7.50 per
share and (iv) 17,443,500 additional shares of common stock issuable upon
exercise of the TdF's put

right or our call right. In addition, following the second anniversary of the
Roll-Up, unless TdF shall have previously exchanged its shares of capital stock
of CTSH in accordance with the Governance Agreement, TdF may require us to
repurchase the shares of capital stock of CTSH held by TdF at fair market
value. Pursuant to the Governance Agreement, we could elect to pay for such
shares in shares of its common stock at a discount of 15% to their market
value. See "Risk Factors--Our Agreements with TdF Give TdF Substantial
Governance and Economic Rights". If we were to issue shares of our common stock
to effect the purchase, such issuance would result in substantial dilution to
our other stockholders. In addition, TdF has the right to acquire additional
shares of common stock pursuant to its preemptive rights under the Governance
Agreement. These shares may, in some cases (such as in connection with the
Proposed BAM JV) result in TdF having the right to acquire shares at below the
then current public market price. Since December 31, 1998, we have granted
options to purchase an additional shares of common stock, of which options
for shares have an exercise price of $ and options for shares have an
exercise price of $ . To the extent that outstanding stock options or warrants
are exercised, there will be further dilution to new investors. See "Risk
Factors--Our Agreements with TdF Give TdF Substantial Governance and Economic
Rights", "--This Offering Will Result in Substantial Dilution to the Value of
Our Common Stock", "Capitalization", "Management--Executive Compensation--Stock
Option Plan" and Notes 8 and 9 of Notes to Consolidated Financial Statements.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The following unaudited pro forma condensed consolidated financial
statements (the "Pro Forma Financial Statements") are based on the historical
financial statements of CCIC and the historical financial statements of the
entities acquired by CCIC during the period presented, adjusted to give effect
to the following transactions (collectively, the "Transactions"):

(1) the Roll-Up;

(2) the IPO;

(3) the conversion of CCIC's senior convertible preferred stock into
common stock (all of which, as of July 17, 1998, had been converted);

(4) the issuance of CCIC's 12 3/4% Exchangeable Preferred Stock due 2010;

(5) the debt and equity offerings;

(6) the Proposed BAM JV;

(7) the Proposed BellSouth Transaction; and

(8) the Proposed Powertel Acquisition.

In this pro forma discussion, we refer to the transactions set forth in
clauses (1) through (4) of the preceding sentence collectively as the 1998
Transactions, and we refer to the Proposed BAM JV, the Proposed BellSouth
Transaction and the Proposed Powertel Acquisition collectively as the Proposed
Transactions. We refer to all of the above transactions as the Transactions.

The Unaudited Pro Forma Condensed Consolidated Statement of Operations for
the year ended December 31, 1998 gives effect to the Transactions as if they
had occurred as of January 1, 1998. The Unaudited Pro Forma Condensed
Consolidated Balance Sheet gives effect to the (1) debt and equity offerings
and (2) the Proposed Transactions as if they had occurred as of December 31,
1998. The pro forma adjustments are described in the accompanying notes and are
based upon available information and certain assumptions that management
believes are reasonable.

[D] Included in the notes accompanying the Pro Forma Financial Statements
are tables summarizing the unaudited pro forma results of operations and
balance sheet for CCIC and its Restricted Subsidiaries (as defined in the
Indenture governing the 10 5/8% discount notes, the "10 5/8% Notes Indenture");
such group of companies is hereinafter referred to as the "Restricted Group".
The Restricted Group excludes CTI and the Proposed BAM JV, both of which are
designated as Unrestricted Subsidiaries (as defined in the 10 5/8% Notes
Indenture) under our debt instruments.

The Pro Forma Financial Statements do not purport to represent what CCIC's
results of operations or financial condition would actually have been had the
1998 Transactions, the debt and equity offerings or the Proposed Transactions
in fact occurred on such dates or to project CCIC's results of operations or
financial condition for any future date or period. The Pro Forma Financial
Statements should be read in conjunction with the consolidated financial
statements and the notes thereto included elsewhere in this document and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".

The Roll-Up, the Proposed BAM JV and the Proposed Powertel Acquisition are
accounted for under the purchase method of accounting. The total purchase price
for the Roll-Up, the Proposed BAM JV and the Proposed Powertel Acquisition have
been allocated to the identifiable tangible and intangible assets and
liabilities of the applicable acquired business based upon CCIC's preliminary
estimate of their fair values with the remainder allocated to goodwill and
other intangible assets. The allocations of the purchase prices are subject to
revision when additional information concerning asset and liability valuations
is obtained; however, the Company does not expect that any such revisions will
have a material effect on its consolidated financial position or results of
operations. The Company has recorded the purchase price for the Roll-Up based
on (i) the number of shares of CCIC's common stock and Class A common stock
exchanged for shares of CTI's capital stock and (ii) the price per share
received by CCIC in our IPO.

Notes to Unaudited Pro Forma Condensed Consolidated Statement of Operations
(Dollars in thousands)

(a) The historical results of operations for CTI are included in CCIC's
historical results of operations for the period from the date of the Roll-
Up, August 21, 1998, through December 31, 1998.

(b) Reflects the historical results of operations of CTI (under U.S. GAAP) for
the periods prior to the consummation of the Roll-Up on August 21, 1998.
Such results have been translated from pounds sterling to U.S. dollars at
the average Noon Buying Rate for the period.

(d) Reflects the incremental amortization of goodwill as a result of the Roll-
Up. Goodwill is being amortized over twenty years.

(e) Reflects the elimination of equity accounting adjustments to include CCIC's
percentage in CTI's earnings and losses.

(f) Reflects decrease in interest expense attributable to the repayment of
borrowings under CCIC's senior credit facility from a portion of the net
proceeds from the issuance of our 12 3/4% exchangeable preferred stock.

(g) Reflects the minority interest in dividends accrued on CTI's Redeemable
Preference Shares.

(h) Reflects (1) decrease in dividends of $4,348 attributable to the conversion
of the outstanding shares of senior convertible preferred stock into shares
of common stock and (2) increase in dividends of $25,682 attributable to 12
3/4% exchangeable preferred stock.

(i) Reflects (1) increase in interest expense of $29,570 as a result of the
issuance of the notes in the debt offering at an assumed interest rate of
% per annum and (2) nonrecurring financing fees of $3,000 related to the
term loans incurred to fund the escrow payments in connection with the
Proposed BellSouth Transaction and the Proposed Powertel Acquisition (the
"Term Loans").

(j) Reflects the historical results of operations of the tower operations to be
contributed to the Proposed BAM JV.

(k) Reflects additional revenues to be recognized by the Proposed BAM JV
pursuant to the BAM global lease and the Formation Agreement.

(l) CCIC expects that the Proposed BAM JV will incur incremental operating
expenses as a stand-alone entity. Such incremental expenses are currently
estimated to amount to approximately $5.2 million per year. In addition,
CCIC expects that it will incur incremental operating expenses as a result
of the Proposed BellSouth Transaction and the Proposed Powertel
Acquisition. Such incremental expenses are currently estimated to amount to
approximately $15.9 million per year. These incremental operating expenses
are based on management's best estimates rather than any contractual
obligations; as such, these amounts have not been presented as adjustments
in the accompanying Pro Forma Financial Statement.

(m) Reflects the incremental depreciation of property and equipment as a result
of the Proposed BAM JV. Property and equipment is being depreciated over
twenty years.

(n) Reflects additional interest expense attributable to borrowings under a

operations.

(p) Reflects additional revenues to be recognized by CCIC in connection with
the Proposed BellSouth Transaction pursuant to the Sublease and the Letter
Agreement. This amount includes $26,640 in revenues to be received from
BellSouth and $7,200 in revenues to be received from other tenants.

(q) Reflects additional costs to be incurred for ground rents in connection
with the Proposed BellSouth Transaction pursuant to the Letter Agreement.

(r) Reflects the incremental depreciation of property and equipment as a result
of the Proposed BellSouth Transaction. Property and equipment is being
depreciated over twenty years.

(s) Reflects the historical results of operations of the tower operations to be
acquired in the Proposed Powertel Acquisition.

(t) Reflects additional revenues to be recognized by CCIC in connection with
the Proposed Powertel Acquisition pursuant to the Master Site Agreements
and the Asset Purchase Agreement.

(u) Reflects the incremental depreciation of property and equipment as a result
of the Proposed Powertel Acquisition. Property and equipment is being
depreciated over twenty years.

SELECTED FINANCIAL AND OTHER DATA OF CCIC

The selected historical consolidated financial and other data for CCIC set
forth below for each of the four years in the period ended December 31, 1998,
and as of December 31, 1995, 1996, 1997 and 1998, have been derived from the
consolidated financial statements of CCIC, which have been audited by KPMG LLP,
independent certified public accountants. The results of operations for the
year ended December 31, 1998 are not comparable to the year ended December 31,
1997, and the results for the year ended December 31, 1997 are not comparable
to the year ended December 31, 1996 as a result of business acquisitions
consummated in 1997 and 1998. Results of operations of these acquired
businesses are included in the Company's consolidated financial statements for
the periods subsequent to the respective dates of acquisition. [[D] The
selected historical financial and other data for the Restricted Group (as
defined) are not intended as alternative measures of operating results or cash
flows from operations (as determined in accordance with generally accepted
accounting principles).] The information set forth below should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Results of Operations--CCIC" and the consolidated
financial statements and the notes thereto of CCIC included elsewhere in this

- --------
(a) Corporate development expenses represent costs incurred in connection with
acquisitions and development of new business initiatives. These expenses
consist primarily of allocated compensation, benefits and overhead costs
that are not directly related to the administration or management of
existing towers. For the year ended December 31, 1997, such expenses
include (i) nonrecurring cash bonuses of $0.9 million paid to certain
executive officers in connection with the CTI Investment and (ii) a
nonrecurring cash charge of $1.3 million related to the purchase by CCIC of
shares of common stock from CCIC's former chief executive officer in
connection with the CTI Investment. See "Certain Relationships and Related
Transactions".
(b) Represents charges related to the issuance of stock options to certain
employees and executives.
(c) Includes a $1.2 million fee received in March 1997 as compensation for
leading the investment consortium which provided the equity financing for
CTI in connection with the CTI Investment.
(d) Represents the aggregate number of sites of CCIC as of the end of each
period.
(e) As of December 31, 1998, CCIC had contracts with 1,365 buildings in the
United States to manage on behalf of such buildings the leasing of space
for antennas on the rooftops of such buildings. A revenue producing rooftop
represents a rooftop where CCIC has arranged a lease of space on such
rooftop and, as such, is receiving payments in respect of its management
contract. CCIC generally does not receive any payment for rooftops under
management unless CCIC actually leases space on such rooftops to third
parties. As of December 31, 1998, CCIC had 1,284 rooftop sites under
management throughout the United States that were not revenue producing but
were available for leasing to customers and, in the United Kingdom, the
Company had 54 revenue producing rooftop sites that were occupied by the
Company's transmitters but were not available for leasing to customers.
(f) EBITDA is defined as operating income (loss) plus depreciation and
amortization and non-cash compensation charges. EBITDA is presented as
additional information because management believes it to be a useful
indicator of CCIC's ability to meet debt service and capital expenditure
requirements. It is not, however, intended as an alternative measure of
operating results or cash flow from operations (as determined in accordance
with generally accepted accounting principles). Furthermore, CCIC's measure
of EBITDA may not be comparable to similarly titled measures of other
companies.
(g) For purposes of computing the ratio of earnings to fixed charges, earnings
represent income (loss) before income taxes, fixed charges and equity in
earnings (losses) of unconsolidated affiliate. Fixed charges consist of
interest expense, the interest component of operating leases and
amortization of deferred financing costs. For the years ended December 31,
1995, 1996, 1997 and 1998, earnings were insufficient to cover fixed
charges by $21,000, $0.9 million, $10.8 million and $37.8 million,
respectively.
(h) The 1995, 1996 and 1997 amounts represent (1) the Senior Convertible
Preferred Stock privately placed by CCIC in August 1997 and October 1997,
all of which has been converted into shares of common stock, and (2) the
Series A Convertible Preferred Stock, the Series B Convertible Preferred
Stock and the Series C Convertible Preferred Stock privately placed by CCIC
in April 1995, July 1996 and February 1997, respectively, all of which has
been converted into shares of common stock in connection with the
consummation of the IPO. The 1998 amount represents the 12 3/4% Senior
Exchangeable Preferred Stock due 2010.

SELECTED FINANCIAL AND OTHER DATA OF CTI

The selected historical financial data for CTI, which was 34.3% owned by
CCIC prior to the Roll-Up, presents (i) selected historical financial data of
the BBC Home Service Transmission Business prior to its acquisition by CTI (the
"Predecessor") for the year ended March 31, 1996 and the eleven and two months
ended February 27, 1997, (ii) selected historical consolidated financial data
of CTI after such acquisition for the one month ended March 31, 1997 and for
the nine months ended December 31, 1997, and (iii) selected historical
consolidated financial data of CTI for the eight months ended August 31, 1998.
The selected historical financial data for the year ended March 31, 1996 and
the eleven months ended February 27, 1997 have been derived from the financial
statements of the Predecessor, which have been audited by KPMG, Chartered
Accountants. The selected financial data for the one month ended March 31, 1997
and the nine months ended December 31, 1997 have been derived from the
consolidated financial statements of CTI, which have been audited by KPMG,
Chartered Accountants. The selected historical financial data for the two
months ended February 27, 1997 have been derived from the unaudited financial
statements of the Predecessor, and the selected historical financial data for
the eight months ended August 31, 1998 have been derived from the unaudited
consolidated financial statements of CTI, which include all adjustments that
CTI considers necessary for a fair presentation of the financial position and
results of operations for that period. The results of operations for the one
month ended March 31, 1997, the nine months ended December 31, 1997 and the
eight months ended August 31, 1998 are not necessarily indicative of the
results of operations of CTI that may be expected for the entire year. CCIC
acquired a majority ownership interest in CTI upon consummation of the Roll-Up
in August 1998 and, as a result, historical financial data of CTI for the year
ended December 31, 1998 is not presented. This information reflects financial
data for CTI as a whole, is not limited to that portion of the financial data
attributable to CCIC's percentage ownership of CTI prior to the Roll-Up and is
not indicative of any distributions or dividends that CCIC might receive in the
future. CTI is subject to significant restrictions on its ability to make
dividends and distributions to CCIC. See "Risk Factors--As a Holding Company,
We Depend on Dividends from Subsidiaries to Meet Cash Requirements or Pay
Dividends". The information set forth below should be read in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Results of Operations--CTI" and the consolidated financial
statements and the notes thereto of CTI included elsewhere in this document.

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

The following discussion sets forth separately the historical consolidated
results of operations of CCIC and CTI and is intended to assist in
understanding (1) CCIC's consolidated financial condition as of December 31,
1998 and its consolidated results of operations for each year in the three-year
period ended December 31, 1998 and (2) CTI's consolidated results of operations
for each twelve-month period in the two-year period ended March 31, 1998. The
statements in this discussion regarding the industry outlook, the Company's
expectations regarding the future performance of its businesses and the other
nonhistorical statements in this discussion are forward-looking statements.
These forward-looking statements are subject to numerous risks and
uncertainties, including but not limited to the uncertainties relating to
decisions on capital expenditures to be made in the future by wireless carriers
and broadcasters and the risks and uncertainties described in "Risk Factors".
This discussion should be read in conjunction with "Unaudited Pro Forma
Condensed Consolidated Financial Statements", "Selected Financial and Other
Data of CCIC", "Selected Financial and Other Data of CTI" and the consolidated
financial statements and the notes thereto included elsewhere in this document.
Results of operations of the acquired businesses that are wholly and majority
owned are included in the Company's consolidated financial statements for the
periods subsequent to the respective dates of acquisition. As such, the
Company's results of operations for the year ended December 31, 1998 are not
comparable to the year ended December 31, 1997, and the results for the year
ended December 31, 1997 are not comparable to the year ended December 31, 1996.

Overview

The continued growth of the Company's business depends substantially on the
condition of the wireless communications and broadcast industries. The Company
believes that the demand for communications sites will continue to grow and
expects that, due to increased competition, wireless carriers will continue to
seek operating and capital efficiencies by (1) outsourcing certain network
services and the build-out and operation of new and existing infrastructure and
(2) co-locating antennas and transmission equipment on multiple tenant towers.
In addition, wireless carriers are beginning to seek to sell their wireless
communications infrastructure to, or establish joint ventures with, experienced
infrastructure providers, such as the Company, that have the ability to manage
networks.

Further, the Company believes that wireless carriers and broadcasters will
continue to seek to outsource the operation of their towers and, eventually,
their transmission networks, including the transmission of their signals.
Management believes that the Company's ability to manage towers and
transmission networks and its proven track record of providing end-to-end
services to the wireless communications and broadcasting industries position it
to capture such business.

The willingness of wireless carriers to utilize the Company's
infrastructure and related services is affected by numerous factors, including
consumer demand for wireless services, interest rates, cost of capital,
availability of capital to wireless carriers, tax policies, willingness to co-
locate equipment, local restrictions on the proliferation of towers, cost of
building towers and technological changes affecting the number of
communications sites needed to provide wireless communications services to a
given geographic area. The Company's revenues that are derived from the
provision of transmission services to the broadcasting industry will be
affected by the timing of the roll-out of digital terrestrial television
broadcasts in both the United Kingdom and the United States, as well as in
other countries around the world, consumer demand for digital terrestrial
broadcasting, interest rates, cost of capital, zoning restrictions on tall
towers and the cost of building towers.

50
<PAGE>

As an important part of its business strategy, the Company will seek (1) to
take advantage of the operating leverage of its site rental business by
increasing the antenna space leased on its owned or managed communications
sites, (2) to leverage its in-house technical and operational expertise, (3) to
expand its tower footprints by partnering with wireless carriers to assume
ownership of their existing towers and by pursuing build-to-suit opportunities
and (4) to acquire existing transmission networks globally as opportunities
arise.

Results of Operations

The Company's primary sources of revenues are from (1) the rental of
antenna space on towers and rooftops sites, (2) the provision of network
services and (3) the provision of analog and digital broadcast transmission
services.

CCIC

CCIC's primary sources of revenues are from (1) the rental of antenna space
on towers and rooftop sites and (2) the provision of network services, which
includes network design and site selection, site acquisition, site development
and construction and antenna installation.

Site rental revenues are received primarily from wireless communications
companies, including cellular, PCS, paging, specialized mobile radio/enhanced
specialized mobile radio ("SMR/ESMR") and microwave operators. Site rental
revenues are generally recognized on a monthly basis under lease agreements,
which typically have original terms of five years (with three or four optional
renewal periods of five years each). Average revenues for CCIC's managed
rooftop sites are less than for the owned and managed towers because a
substantial portion of the revenues from the tenants at rooftop sites is
remitted to the building owner or manager.

Network services revenues consist of revenues from (1) network design and
site selection, (2) site acquisition, (3) site development and construction,
(4) antenna installation and (5) other services. Network services revenues are
received primarily from wireless communications companies. Network services
revenues are recognized under service contracts which provide for billings on
either a fixed price basis or a time and materials basis. Demand for CCIC's
network services fluctuates from period to period and within periods. See "Risk
Factors--Variability in Demand for Network Services May Reduce the
Predictability of Our Results". Consequently, the operating results of CCIC's
network services businesses for any particular period may vary significantly,
and should not be considered as indicative of longer-term results. CCIC also
derives revenues from the ownership and operation of microwave radio and SMR
networks in Puerto Rico where CCIC owns radio wave spectrum in the 2,000 MHz
and 6,000 MHz range (for microwave radio) and the 800 MHz range (for SMR).
These revenues are generally recognized under monthly management or service
agreements.

Costs of operations for site rental primarily consist of land leases,
repairs and maintenance, utilities, insurance, property taxes and monitoring
costs as well as, in the case of managed sites, rental payments. For any given
tower, such costs are relatively fixed over a monthly or an annual time period.
As such, operating costs for owned towers do not generally increase
significantly as additional customers are added. However, rental expenses at
certain managed towers increase as additional customer antennas are added,
resulting in higher incremental revenues but lower incremental margins than on
owned towers. Costs of operations for network services consist primarily of
employee compensation and related benefits costs, subcontractor services,
consulting fees, and other on-site construction and materials costs. CCIC
incurs these network services costs (1) to support its internal operations,
including construction and maintenance of its owned towers, and (2) to maintain
the employees necessary to provide end-to-end services to third parties
regardless of the level of such business at any time. The Company believes that
its experienced staff enables it to

51
<PAGE>

provide the type of end-to-end services that enhance its ability to acquire
access to the infrastructure of wireless carriers and to attract significant
build-to-suit contracts.

General and administrative expenses consist primarily of employee
compensation and related benefits costs, advertising, professional and
consulting fees, office rent and related expenses and travel costs. Corporate
development expenses represent costs incurred in connection with acquisitions
and development of new business initiatives. These expenses consist primarily
of allocated compensation, benefits and overhead costs that are not directly
related to the administration or management of existing towers.

Depreciation and amortization charges relate to CCIC's property and
equipment (primarily towers, construction equipment and vehicles), goodwill and
other intangible assets recorded in connection with business acquisitions.
Depreciation of towers and amortization of goodwill are computed with a useful
life of 20 years. Amortization of other intangible assets (principally the
value of existing site rental contracts at Crown) is computed with a useful
life of 10 years. Depreciation of construction equipment and vehicles are
generally computed with useful lives of 10 years and 5 years, respectively.

In May 1997, the Company consummated the TEA acquisition and the
TeleStructures acquisition. In August 1997, the Company consummated the
acquisition of Crown Communication. In August 1998, the Company consummated a
share exchange with the shareholders of CTSH, pursuant to which the Company's
ownership of CTSH increased from approximately 34.3% to 80%. In October 1998,
CTI consummated the Millennium acquisition. Results of operations of these
acquired businesses are included in the Company's consolidated financial
statements for the periods subsequent to the respective dates of acquisition.
As such, the Company's results of operations for the year ended December 31,
1998 are not comparable to the year ended December 31, 1997, and the results
for the year ended December 31, 1997 are not comparable to the year ended
December 31, 1996. See "--CTI" for a description of the revenues and operating
expenses that are included in CCIC's consolidated results of operations
subsequent to the consummation of the share exchange in August 1998.

Comparison of Years Ended December 31, 1998 and 1997

Consolidated revenues for 1998 were $113.1 million, an increase of $81.7
million from 1997. This increase was primarily attributable to (i) a $64.0
million, or 581.5%, increase in site rental and broadcast transmission
revenues, of which $52.5 million was attributable to CTI and $11.5 million was
attributable to the Crown operations; (ii) an $11.4 million increase in network
services revenues from the Crown operations; and (iii) $5.6 million in network
services revenues from CTI.

Costs of operations for 1998 were $47.8 million, an increase of $32.5
million from 1997. This increase was primarily attributable to (i) a $24.0
million increase in site rental and broadcast transmission costs, of which
$20.1 million was attributable to CTI and $3.9 million was attributable to the
Crown operations; (ii) a $3.8 million increase in network services costs
related to the Crown operations; and (iii) $4.2 million in network services
costs from CTI. Costs of operations for site rental and broadcast transmission
as a percentage of site rental and broadcast transmission revenues increased to
35.0% for 1998 from 20.1% for 1997, primarily due to (1) higher costs
attributable to the CTI operations which are inherent with CTI's broadcast
transmission business, and (2) higher costs for the Crown operations. Costs of
operations for network services as a percentage of network services revenues
decreased to 56.7% for 1998 from 64.4% for 1997, primarily due to improved
margins from the Crown operations. Margins from the Crown network services
operations vary from period to period, often as a result of increasingly
competitive market conditions.

General and administrative expenses for 1998 were $23.6 million, an
increase of $16.7 million from 1997. This increase was primarily attributable
to (i) an $11.3 million increase in expenses

53
<PAGE>

related to the Crown operations; (ii) a $2.8 million increase in expenses at
our corporate office; and (iii) $2.4 million in expenses at CTI. General and
administrative expenses as a percentage of revenues decreased for 1998 to 20.8%
from 21.7% for 1997 because of lower overhead costs as a percentage of revenues
for CTI, partially offset by higher overhead costs as a percentage of revenues
for Crown and the increase in costs at our corporate office.

Corporate development expenses for 1998 were $4.6 million, a decrease of
$1.1 million from 1997. Corporate development expenses for 1997 included
nonrecurring compensation charges associated with the CTI Investment of (i)
$0.9 million for certain executive bonuses and (ii) the repurchase of shares of
our common stock from a member of our Board of Directors, which resulted in
compensation charges of $1.3 million. Corporate development expenses for 1998
included discretionary bonuses related to the Company's performance totaling
approximately $1.8 million for certain members of our management.

We have recorded non-cash compensation charges of $12.8 million related to
the issuance of stock options to certain employees and executives. Such charges
are expected to amount to approximately $1.6 million per year through 2002 and
approximately $0.8 million in 2003. See "--Compensation Charges Related to
Stock Option Grants".

Depreciation and amortization for 1998 was $37.2 million, an increase of
$30.3 million from 1997. This increase was primarily attributable to (1) a $9.5
million increase in depreciation and amortization related to the property and
equipment, goodwill and other intangible assets acquired in the Crown
acquisition; and (2) $20.3 million of depreciation and amortization related to
the property and equipment and goodwill from CTI.

The equity in earnings (losses) of unconsolidated affiliate represents our
34.3% share of CTI's net earnings (losses) for the periods from March 1997
through August 1998 (at which time the share exchange with CTI's shareholders
was consummated). For the eight months ended August 31, 1998, after making
appropriate adjustments to CTI's results of operations for such period to
conform to generally accepted accounting principles of the United States, CTI
had net revenues, operating income, interest expense (including amortization of
deferred financing costs) and net income of $97.2 million, $18.6 million, $13.4
million and $6.0 million, respectively. Included in CTI's results of operations
for such period are non-cash compensation charges for approximately $3.8
million related to the issuance of stock options to certain members of CTI's
management.

Interest and other income for 1997 includes a $1.2 million fee received in
March 1997 as compensation for leading the investment consortium which provided
the equity financing for CTI. Interest income for 1998 resulted primarily from
(1) the investment of excess proceeds from the sale of the 10 5/8% discount
notes in November 1997; and (2) the investment of the net proceeds from the IPO
in August 1998. See "--Liquidity and Capital Resources".

Interest expense and amortization of deferred financing costs for 1998 was
$29.1 million, an increase of $19.8 million, or 214.3%, from 1997. This
increase was primarily attributable to amortization of the original issue
discount on the 10 5/8% Notes and interest on CTI's indebtedness.

Minority interests represent the minority shareholder's 20% interest in
CTI's operations.

Comparison of Years Ended December 31, 1997 and 1996

Consolidated revenues for 1997 were $31.4 million, an increase of $25.2
million from 1996. This increase was primarily attributable to (1) a $5.4
million, or 96.1%, increase in site rental revenues, of which $4.2 million was
attributable to the Crown operations and $0.7 million was attributable to the
Puerto Rico operations; (2) $10.4 million in network services revenues from
TEA; and (3) $7.2 million in network services revenues from the Crown
operations. The remainder of the increase was largely attributable to higher
revenues from SMR and microwave radio services in Puerto Rico and the monthly
service fees received from CTI beginning in March 1997.

54
<PAGE>

Costs of operations for 1997 were $15.4 million, an increase of $14.1
million from 1996. This increase was primarily attributable to (1) $8.5 million
of network services costs related to the TEA operations; (2) $3.9 million of
network services costs related to the Crown operations; and (3) $0.9 million in
site rental costs attributable to the Crown operations. Costs of operations for
site rental as a percentage of site rental revenues decreased to 20.1% for 1997
from 23.0% for 1996 because of increased utilization of the towers located in
the southwestern United States and Puerto Rico. Costs of operations for network
services as a percentage of network services revenues were 64.4% for 1997,
reflecting lower margins that are inherent in the network services businesses
acquired in 1997.

General and administrative expenses for 1997 were $6.8 million, an increase
of $5.1 million from 1996. This increase was primarily attributable to $3.0
million of expenses related to the Crown operations and $1.4 million of
expenses related to the TEA operations, along with an increase in costs of $0.2
million at CCIC's corporate office. General and administrative expenses as a
percentage of revenues decreased for 1997 to 21.7% from 27.0% for 1996 because
of lower overhead costs as a percentage of revenues for Crown and TEA.

Corporate development expenses for 1997 were $5.7 million, an increase of
$4.4 million from 1996. A substantial portion of this increase was attributable
to nonrecurring compensation charges associated with the CTI Investment of (1)
$0.9 million for certain executive bonuses and (2) the repurchase of shares of
CCIC's common stock from a member of its Board of Directors, which resulted in
compensation charges of $1.3 million. The remaining $2.2 million of the
increase in corporate development expenses was attributable to a higher
allocation of personnel costs, along with an overall increase in such costs,
associated with an increase in acquisition and business development activities.

Depreciation and amortization for 1997 was $7.0 million, an increase of
$5.7 million from 1996. This increase was primarily attributable to (1) $4.7
million of depreciation and amortization related to the property and equipment,
goodwill and other intangible assets acquired in the Crown acquisition; (2)
$0.5 million of depreciation and amortization related to the property and
equipment and goodwill acquired in the TEA and TeleStructures acquisitions; and
(3) $0.3 million resulting from twelve months of depreciation related to the
property and equipment acquired in the Puerto Rico acquisition.

The equity in losses of unconsolidated affiliate of $1.1 million represents
CCIC's 34.3% share of CTI's net loss for the period from March through December
1997. After making appropriate adjustments to CTI's results of operations for
such period to conform to generally accepted accounting principles of the
United States, CTI had net revenues, operating income, interest expense
(including amortization of deferred financing costs) and net losses of $103.5
million, $16.5 million, $20.4 million and $3.3 million, respectively.

Interest and other income for 1997 includes a $1.2 million fee received in
March 1997 as compensation for leading the investment consortium which provided
the equity financing for CTI, the impact on earnings of which was partially
offset by certain executive bonuses related to the CTI Investment and included
in corporate development expenses. Interest income for 1997 resulted primarily
from the investment of excess proceeds from the sale of CCIC's Series C
convertible preferred stock in February 1997.

Interest expense and amortization of deferred financing costs for 1997 was
$9.3 million, an increase of $7.5 million, or 413.3%, from 1996. This increase
was primarily attributable to (1) commitment fees related to an unfunded
interim loan facility related to the Crown acquisition and an unfunded
revolving credit facility; (2) interest on notes payable to the former
stockholders of Crown for a portion of the purchase price of the Crown
Communication Inc.; (3) amortization of the original issue discount on the 10
5/8% discount notes; (4) interest and fees associated with borrowings under

55
<PAGE>

CCIC's bank credit facility which were used to finance the Crown acquisition on
an interim basis; (5) interest on outstanding borrowings assumed in connection
with the Crown acquisition; and (6) interest on borrowings under CCIC's bank
credit facility which were used to finance the acquisition of the Puerto Rico
system.

CTI

CTI's primary sources of revenues are from (1) the provision of analog and
digital broadcast transmission services to the BBC and commercial broadcasters,
(2) the rental of antenna space on towers and (3) the provision of network
services, which includes broadcast consulting, network design and site
selection, site acquisition, site development and antenna installation and site
management and other services.

Broadcast transmission services revenues are received for both analog and
digital transmission services. Monthly analog transmission revenues are
principally received from the BBC under a contract with an initial 10-year term
through March 31, 2007. Digital transmission services revenues from the BBC and
ONdigital are recognized under contracts with initial terms of 12 years through
November 15, 2010. Monthly revenues from these digital transmission contracts
increase over time as the network rollout progresses. See "Business--U.K.
Operations--Significant Contracts".

Site rental revenues are received from other broadcast transmission service
providers (primarily NTL) and wireless communications companies, including all
four U.K. cellular operators (Cellnet, Vodafone, One2One and Orange). As of
December 31, 1998, approximately 200 companies rented space on approximately
514 of CTI's 919 towers and rooftops. Site rental revenues are generally
recognized on a monthly basis under lease agreements with original terms of
three to twelve years. Such lease agreements generally require annual payments
in advance, and include rental rate adjustment provisions between one and three
years from the commencement of the lease. Site rental revenues are expected to
become an increasing portion of CTI's total U.K. revenue base, and the Company
believes that the demand for site rental from communication service providers
will increase in line with the expected growth of these communication services
in the United Kingdom.

Network services revenues consist of (1) network design and site selection,
site acquisition, site development and antenna installation (collectively,
"network design and development") and (2) site management and other services.
Network design and development services are provided to (1) a number of
broadcasting and related organizations, both in the United Kingdom and other
countries; (2) all four U.K. cellular operators; and (3) a number of other
wireless communications companies, including Dolphin and Highway One. These
services are usually subject to a competitive bid, although a significant
proportion result from an operator coming onto an existing CTI site. Revenues
from such services are recognized on either a fixed price or a time and
materials basis. Site management and other services, consisting of both network
monitoring and equipment maintenance, are carried out in the United Kingdom for
a number of emergency service organizations. Revenues for such services are
received under contracts with original terms of between three and five years.
They provide for fixed prices with respect to network monitoring and variable
pricing dependent on the level of equipment maintenance carried out in a given
period.

Costs of operations for broadcast transmission services consist primarily
of employee compensation and related benefits costs, utilities, rental payments
under the Site-Sharing Agreement with NTL, circuit costs and repairs and
maintenance on both transmission equipment and structures.

Site rental operating costs consist primarily of employee compensation and
related benefits costs, utilities and repairs and maintenance. The majority of
such costs are relatively fixed in nature, with increases in revenue from new
installations on existing sites generally being achieved without a
corresponding increase in costs.

<PAGE>

Costs of operations for network services consist primarily of employee
compensation and related benefits costs and on-site construction and materials
costs.

General and administrative expenses consist primarily of office occupancy
and related expenses, travel costs, professional and consulting fees,
advertising, insurance and employee training and recruitment costs. Corporate
development expenses represent costs incurred in connection with acquisitions
and development of new business initiatives. These expenses consist primarily
of external professional fees related to specific activities and allocated
compensation, benefits and overhead costs that are not directly related to the
administration or management of CTI's existing lines of business.

Depreciation and amortization charges relate to CTI's property and
equipment (primarily towers, broadcast transmission equipment and associated
buildings) and goodwill recorded in connection with the acquisition of the Home
Service Transmission business from the BBC (the "BBC Home Service Transmission
Business"). Depreciation of towers is computed with useful lives of 20 to 25
years; depreciation of broadcast transmission equipment is computed with a
useful life of 20 years; and depreciation of buildings is computed with useful
lives ranging from 20 to 50 years. Amortization of goodwill is computed with a
useful life of 20 years.

The following information is derived from the Consolidated Profit and Loss
Accounts of (i) CTI for periods subsequent to February 28, 1997 (the date of
inception of CTI's operations) and (ii) the BBC Home Service Transmission
Business for periods prior to that date. For purposes of the following
discussion, CTI's results for the month ended March 31, 1997 have been combined
with the results of the BBC Home Service Transmission Business for the eleven
months ended February 27, 1997, and CTI's results for the nine months ended
December 31, 1997 have been combined with its results for the three months
ended March 31, 1998. The following discussion presents an analysis of such
combined results for the twelve-month periods ended March 31, 1998 and 1997.
Results for CTI are not comparable to results from the BBC Home Service
Transmission Business due to differences in the carrying amounts of property
and equipment and goodwill. As of December 31, 1997, CTI changed its fiscal
year end for financial reporting purposes from March 31 to December 31; as
such, the results for the three months ended March 31, 1998 are unaudited.

CTI uses the U.K. pound sterling as the functional currency for its
operations. The following amounts have been translated to U.S. dollars using
the average Noon Buying Rate for each period. The following amounts reflect
certain adjustments to present the results of operations in accordance with
U.S. generally accepted accounting principles ("GAAP"). For the results of the
BBC Home Service Transmission Business, such adjustments affect depreciation
and amortization expense as a result of differences in the carrying amounts for
property and equipment; for CTI, such adjustments affect (1) operating expenses
as a result of differences in the accounting for pension costs, and (2)
interest expense as a result of the capitalization of interest costs in
connection with constructed assets.

Comparison of Twelve Months Ended March 31, 1998 and Twelve Months Ended March
31, 1997

Consolidated revenues for the twelve months ended March 31, 1998 were
$127.3 million, an increase of $5.1 million from the twelve months ended March
31, 1997. This increase was primarily attributable to (1) a $1.4 million
increase in broadcast transmission services and site rental revenues and (2) a
$3.6 million increase in network services and other revenues. Revenues from the
BBC for the twelve months ended March 31, 1998 amounted to $79.5 million, or
62.5% of total revenues, as compared to $85.5 million, or 70.0% of total
revenues, for the twelve months ended March 31, 1997. Revenues from NTL for the
twelve months ended March 31, 1998 amounted to $11.8 million, or 9.2% of total
revenues. Network services revenues for the twelve months ended March 31, 1998
consisted of $10.6 million from network design and development services and
$3.1 million from site management and other services.

Costs of operations for the twelve months ended March 31, 1998 were $60.0
million, a decrease of $7.2 million from the twelve months ended March 31,
1997. This decrease was primarily attributable to a $7.4 million decrease in
broadcast transmission services and site rental costs, partially offset by a
$0.2 million increase in network services and other costs. Costs of operations
as a percentage of revenues for broadcast transmission services and site rental
were 47.5% for the

58
<PAGE>

twelve months ended March 31, 1998, as compared to 54.7% for the twelve months
ended March 31, 1997. This decrease was attributable to (1) increases in site
rental revenues from existing sites with little change in site operating costs;
and (2) the elimination, as of February 28, 1997, of certain costs recharged to
the BBC Home Service Transmission Business by the BBC. Costs of operations as a
percentage of revenues for network services and other were 44.2% for the twelve
months ended March 31, 1998, as compared to 58.6% for the twelve months ended
March 31, 1997. This decrease was attributable to (1) a higher proportion of
broadcast consulting revenues, which result in higher margins than certain
other network design and development services and (2) the elimination, as of
February 28, 1997, of certain costs recharged to the BBC Home Service
Transmission Business by the BBC. Costs of operations for site rental and
broadcast transmission for the twelve months ended March 31, 1998 includes non-
cash compensation charges for $1.1 million related to the issuance of stock
options to certain employees.

General and administrative expenses for the twelve months ended March 31,
1998 were $8.6 million, an increase of $1.4 million from the twelve months
ended March 31, 1997. As a percentage of revenues, general and administrative
expenses were 6.8% and 5.9% for the twelve months ended March 31, 1998 and
1997, respectively. This increase was attributable to costs incurred by CTI as
a separate enterprise which were not directly incurred by the BBC Home Service
Transmission Business as a part of the BBC.

Corporate development expenses for the twelve months ended March 31, 1998
relate primarily to costs incurred in connection with certain projects in
Australasia and non-cash compensation charges for $1.8 million related to the
issuance of stock options to certain executives.

Depreciation and amortization for the twelve months ended March 31, 1998
was $37.4 million, an increase of $20.1 million from the twelve months ended
March 31, 1997. Monthly charges for depreciation and amortization increased for
periods subsequent to February 28, 1997 due to (i) a decrease in the estimated
useful lives for certain transmission and power plant equipment from 25 to 20
years; and (ii) the amortization of goodwill recorded in connection with the
acquisition of the BBC Home Service Transmission Business.

Interest and other income for the twelve months ended March 31, 1998
resulted primarily from (i) the investment of excess proceeds from amounts
drawn under CTI's bank credit facilities in February 1997; and (ii) the
investment of cash generated from operations during the period.

Interest expense and amortization of deferred financing costs for the
twelve months ended March 31, 1998 was $24.2 million. This amount was comprised
of (1) $4.9 million related to amounts drawn under the CTI Credit Facility; (2)
$15.6 million related to the CTI Bonds; and (3) $3.7 million for the
amortization of deferred financing costs. Interest expense and amortization of
deferred financing costs of $1.4 million for the twelve months ended March 31,
1997 was attributable to amounts drawn under the CTI Credit Facility. The BBC
Home Service Transmission Business did not incur any financing costs as a part
of the BBC prior to February 28, 1997.

Liquidity and Capital Resources

59
<PAGE>

issuances of debt securities and the issuance of promissory notes to sellers.
Since its inception, CTI has generally funded its activities (other than the
acquisition of the BBC Home Service Transmission Business) through cash
provided by operations and borrowings under CTI's credit facility. CTI financed
the acquisition of the BBC Home Service Transmission Business with the proceeds
from equity contributions and the issuance of CTI's 9% bonds.

For the years ended December 31, 1996, 1997 and 1998, our net cash provided
by (used for) operating activities was ($0.5 million), ($0.6 million) and $45.0
million, respectively. For the years ended December 31, 1996, 1997 and 1998,
our net cash provided by financing activities was $21.2 million, $159.8 million
and $345.2 million, respectively. Our primary financing-related activities in
1998 included the following:

Exchangeable Preferred Stock Offering. On December 16, 1998, we privately
placed 200,000 shares of our 12 3/4% Senior Exchangeable Preferred Stock
due 2010, with a liquidation preference of $1,000 per share, resulting in
net proceeds to us of approximately $193.0 million. We used a portion of
the net proceeds of the exchangeable preferred stock offering to repay our
outstanding indebtedness under CCI's senior credit facility. We intend to
use the remainder of the net proceeds of the exchangeable preferred stock
offering to finance a portion of our investment in the Proposed BAM JV.

Initial Public Offering. On August 18, 1998, we consummated our IPO at a
price to the public of $13.00 per share. We sold 12,320,000 shares of our
common stock and received proceeds of $151.0 million (after underwriting
discounts of $9.1 million but before other expenses of the IPO, which
totaled approximately $4.1 million). We intend to use the net proceeds from
the IPO to finance a portion of our investment in the Proposed BAM JV.

Capital expenditures were $138.8 million for the twelve months ended
December 31, 1998, of which $3.7 million were for CCIC, $84.9 million was for
CCI and $50.2 million were for CTI. We anticipate that we will build, through
the end of 1999, approximately 750 towers in the United States at a cost of
approximately $175.0 million and approximately 200 towers in the United Kingdom
at a cost of approximately $23.0 million. We also expect that the capital
expenditure requirements related to the roll-out of digital broadcast
transmission in the United Kingdom will be approximately (Pounds)40.0 million
($66.5 million).

In addition to capital expenditures in connection with build-to-suits, we
expect to apply a significant amount of capital to finance the cash portion of
the consideration being paid in connection with the Proposed Transactions.

In connection with the Proposed BAM JV, we will contribute, in addition to
other consideration, $250.0 million in cash to the joint venture. The joint
venture expects to borrow $180.0 million under a committed $250.0 million
revolving credit facility, following which the joint venture will make a $380.0
million cash distribution to BAM. We have allocated the net proceeds of our IPO
and a portion of the net proceeds of our 12 3/4% exchangeable preferred stock
offering to finance our cash contribution to the joint venture.

In connection with the Proposed BellSouth Transaction, we will pay
BellSouth, in addition to other consideration, $430.0 million in cash. We have
deposited $50.0 million in an escrow account pending the first closing of the
transaction, which we funded through a loan agreement we entered into on March
15, 1999. We expect to use a portion of the net proceeds of the offerings to
finance this transaction.

In connection with the Proposed Powertel Acquisition, we will pay Powertel
$275.0 million in cash. We have deposited $50.0 million, which we funded
through the March 15, 1999 loan

60
<PAGE>

agreement, in an escrow account to be applied to the purchase price at closing.
We expect to use a portion of the net proceeds of the offerings to finance this
transaction.

We expect that the consummation of the Proposed Transactions and the
execution of our build-to-suit program will have a material impact on our
liquidity. We expect that once integrated, these transactions will have a
positive impact on liquidity, but will require some period of time to offset
the initial adverse impact on liquidity. In addition, we believe that as new
build to suit towers become operational and we begin to add tenants, they
should result in a long-term increase in liquidity.

Our liquidity may also be materially impacted if we fail to consummate any
or all of the Proposed Transactions. In the event we consummate the offerings
and subsequently fail to consummate the Proposed BAM JV, the Proposed BellSouth
Transaction or the Proposed Powertel Acquisition, the proceeds of the offerings
or, in the case of the Proposed BAM JV, the proceeds of our prior 12 3/4%
exchangeable preferred stock offering, would no longer be required to be
allocated to finance such transaction and would be available to us as
additional liquidity. If the Proposed Transaction giving rise to such
additional liquidity were the Proposed BellSouth Transaction or the Proposed
Powertel Acquisition, the increase in our liquidity could be somewhat offset by
any portion of the escrow payments made in connection with such transactions
that we may forfeit as a result of not closing such transactions. See "Risk
Factors--The Proposed Transactions".

As of December 31, 1998, after giving pro forma effect to the offerings, we
would have had consolidated cash and cash equivalents of $962.6 million
(including $6.5 million at CTI), consolidated long-term debt of $729.7 million,
consolidated redeemable preferred stock of $201.1 million and consolidated
stockholders' equity of $1,114.6 million. As of December 31, 1998, after giving
pro forma effect to the offerings and the Proposed Transactions, we would have
had consolidated cash and cash equivalents of $49.6 million (including $6.5
million at CTI and $45.9 million at the Proposed BAM JV), consolidated long-
term debt of $909.7 million, consolidated redeemable preferred stock of $201.1
million and consolidated stockholders' equity of $1,491.6 million.

As of March 1, 1999, CCI and its subsidiaries had unused borrowing
availability under its senior credit facility of approximately $54.0 million,
and CTI had unused borrowing availability under its credit facility of
approximately (Pounds)24.0 million ($39.9 million). As of December 31, 1998,
CCI and its subsidiaries and CTI and its subsidiaries had approximately $77.6
million and (Pounds)30.8 million ($51.2 million) of unused borrowing
availability, respectively, under CCI's senior credit facility and CTI's credit
facility. Upon its formation, the Proposed BAM JV will borrow $180.0 million
under a committed $250.0 million credit facility. CCI's senior credit facility
and CTI's credit facility require, and the

61
<PAGE>

Proposed BAM JV credit facility will require, that the respective borrowers
maintain certain financial covenants; in addition, all three credit facilities
place restrictions on the ability of the borrower and its subsidiaries to,
among other things, incur debt and liens, pay dividends, make capital
expenditures, undertake transactions with affiliates and make investments.
These facilities also limit the ability of the borrowing subsidiaries to pay
dividends to CCIC.

Prior to May 15, 2003, the interest expense on our 10 5/8% discount notes
will be comprised solely of the amortization of original issue discount.
Thereafter, the 10 5/8% discount notes will require annual cash interest
payments of approximately $26.7 million. Prior to December 15, 2003, we do not
expect to pay cash dividends on our exchangeable preferred stock or, if issued,
cash interest on the exchange debentures. Thereafter, assuming all dividends or
interest have been paid-in-kind, our exchangeable preferred stock or, if
issued, the exchange debentures will require annual cash dividend or interest
payments of approximately $47.8 million. Annual cash interest payments on the
CTI Bonds are (Pounds)11.25 million ($18.7 million). In addition, CCI's senior
credit facility and CTI's credit facility will require periodic interest
payments on amounts borrowed thereunder. Our ability to make scheduled payments
of principal of, or to pay interest on, our debt obligations, and our ability
to refinance any such debt obligations (including our 10 5/8% discount notes
and the CTI Bonds), will depend on our future performance, which, to a certain
extent, is subject to general economic, financial, competitive, legislative,
regulatory and other factors that are beyond our control. We anticipate that we
may need to refinance all or a portion of our indebtedness (including our 10
5/8% discount notes and the CTI Bonds) on or prior to its scheduled maturity.
There can be no assurance that we will be able to effect any required
refinancings of our indebtedness on commercially reasonable terms or at all.
See "Risk Factors".

Compensation Charges Related to Stock Option Grants

During the period from April 24, 1998 through July 15, 1998, we granted
options to employees and executives for the purchase of 3,236,980 shares of our
common stock at an exercise price of $7.50 per share. Of such options, options
for 1,810,730 shares vested upon consummation of the IPO and the remaining
options for 1,426,250 shares will vest at 20% per year over five years,
beginning one year from the date of grant. In addition, we have assigned our
right to repurchase shares of our common stock from a stockholder (at a price
of $6.26 per share) to two individuals (including a newly-elected director)
with respect to 100,000 of such shares. Since the granting of these options and
the assignment of these rights to repurchase shares occurred subsequent to the
date of the share exchange agreement with CTI's shareholders and at prices
substantially below the price to the public in the IPO, we have recorded a non-
cash compensation charge related to these options and shares based upon the
difference between the respective exercise and purchase prices and the price to
the public in the IPO. Such compensation charge will total approximately $18.4
million, of which approximately $10.6 million was recognized upon consummation
of the IPO (for such options and shares which vested upon consummation of the
IPO), and the remaining $7.8 million is being recognized over five years
(approximately $1.6 million per year) through the second quarter of 2003. An
additional $1.6 million in non-cash compensation charges will be recognized
through the third quarter of 2001 for stock options issued to certain members
of CTI's management prior to the consummation of the share exchange.

Impact of Recently Issued Accounting Standards

62
<PAGE>

incurred and broadly defines such costs. We have deferred certain costs
incurred in connection with potential business initiatives and new geographic
markets, and SOP 98-5 will require that such deferred costs be charged to
results of operations upon its adoption. SOP 98-5 is effective for fiscal
years beginning after December 15, 1998. We will adopt the requirements of SOP
98-5 as of January 1, 1999. The cumulative effect of the change in accounting
principle for the adoption of SOP 98-5 will result in a charge to results of
operations in our financial statements for the three months ending March 31,
1999; it is currently estimated that such charge will amount to approximately
$2,300,000.

In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS
133"). SFAS 133 requires that derivative instruments be recognized as either
assets or liabilities in the consolidated balance sheet based on their fair
values. Changes in the fair values of such derivative instruments will be
recorded either in results of operations or in other comprehensive income,
depending on the intended use of the derivative instrument. The initial
application of SFAS 133 will be reported as the effect of a change in
accounting principle. SFAS 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. We will adopt the requirements of SFAS
133 in our financial statements for the three months ending March 31, 2000. We
have not yet determined the effect that the adoption of SFAS 133 will have on
our consolidated financial statements.

Year 2000 Compliance

The year 2000 problem is the result of computer programs having been
written using two digits (rather than four) to define the applicable year. Any
of our computer programs that have date-sensitive software may recognize a
date using "00" as 1900 rather than the year 2000, or may not recognize the
date at all. This could result in a system failure or miscalculations causing
disruption of operations including, among other things, a temporary inability
to process transactions, send invoices, or engage in similar normal business
activities.

In 1997 we established a year 2000 project to ensure that the issue
received appropriate priority and that necessary resources were made
available. This project includes the replacement of our worldwide business
computer systems with systems that use programs primarily from J.D. Edwards,
Inc. The new systems are expected to make approximately 90% of our business
computer systems year 2000 compliant and are in production today. Remaining
business software programs, including those supplied by vendors, will be made
year 2000 compliant through the year 2000 project or they will be retired.
None of our other information technology projects has been delayed due to the
implementation of the year 2000 project.

Our year 2000 project is divided into the following phases: (1)
inventorying year 2000 items; (2) assigning priorities to identified items;
(3) assessing the year 2000 compliance of items determined to be material to
us; (4) repairing or replacing material items that are determined not to be
year 2000 compliant; (5) testing material items; and (6) designing and
implementing contingency and business continuation plans for each organization
and company location. We have completed the inventory and priority assessment
phases and are 90% complete with the assessing compliance phase. The remaining
items include various third party assurances regarding the year 2000 status of
their operations. We are now continuing with the testing phase of the year
2000 project. All critical broadcast equipment and non-information technology
related equipment has been tested and is either year 2000 compliant, has been
designated as year 2000 ready, or will be repaired or replaced by June 1999. A
year 2000 ready designation implies the equipment or system will function
without adverse effects beyond year 2000 but may not be aware of the century.
All critical information technology systems have been designated year 2000
compliant or are scheduled to be retired or remediated by July 1999. The
testing phase is ongoing as hardware or system software is

63
<PAGE>

remediated, upgraded or replaced. Testing as well as remediation is scheduled
for completion in July 1999. The final phase of our year 2000 project,
contingency planning, will be completed and tested to the extent possible by
September 1999.

We have expended $6.9 million on the year 2000 project through December 31,
1998, of which approximately $6.8 million related to the implementation of the
J.D. Edwards Systems and related hardware. Funds for the year 2000 project are
provided from a separate budget of $0.6 million for all items.

The failure to correct a material year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect our results of
operations, liquidity and financial condition. Due to the general uncertainty
inherent in the year 2000 problem, resulting in part from the uncertainty of
the year 2000 readiness of third-party suppliers and customers, we are unable
to determine at this time whether the consequences of year 2000 failures will
have a material impact on our results of operations, liquidity or financial
condition. The year 2000 project is expected to significantly reduce our level
of uncertainty about the year 2000 problem and, in particular, about the year
2000 compliance and readiness of our material business partners. We believe
that, with the implementation of new business systems and completion of the
project as scheduled, the possibility of significant interruptions of normal
operations should be reduced.

INDUSTRY BACKGROUND

General

The Company owns, operates and manages wireless communications and
broadcast transmission infrastructure, including towers and other
communications sites, and also provides a full range of complementary network
support services. Each of the wireless communications and broadcasting
industries is currently experiencing a period of significant change.

The wireless communications industry is growing rapidly as new wireless
technologies are developed and consumers become more aware of the benefits of
wireless services. Wireless technologies are being used in more applications
and the cost of wireless services to consumers is declining. A significant
number of new competitors in the wireless communications industry have
developed as additional frequency spectrum has become available for a wide
range of uses, most notably Personal Communications Services ("PCS") (known as
"PCN" in the United Kingdom). This competition, combined with an increasing
reliance on wireless communications by consumers and businesses, has led to an
increased demand for higher quality, uninterrupted service and improved
coverage, which, in turn, has led to increased demand for communications sites
as new carriers build out their networks and existing carriers upgrade and
expand their networks to maintain their competitiveness. These trends are
affecting the wireless communications industry around the world.

As the wireless communications industry has become more competitive,
wireless carriers have sought operating and capital efficiencies by outsourcing
certain network services and the build-out and operation of new and existing
infrastructure and by co-locating transmission equipment with other carriers on
multiple tenant towers. The need for co-location has also been driven by the
growing trend by municipalities to slow the proliferation of towers. Further,
the Company believes that there has been a fundamental shift in strategy among
established wireless carriers relating to infrastructure ownership. The Company
believes that in order to free up capital for the growth and management of
their customer bases and expansion of their service offerings, such carriers
are beginning to seek to sell their wireless communications infrastructure to,
or establish joint ventures with, experienced infrastructure providers that
have the ability to manage networks. The Company believes that those
infrastructure providers with a proven track record of providing end-to-end
services will be best positioned to successfully acquire access to such
wireless communications infrastructure.

The television broadcasting industry is experiencing significant change
because of the impending widespread deployment of digital terrestrial
television broadcasting (known as "DTV" in the United States and "DTT" in the
United Kingdom). In the United States, the FCC has required the four major
networks (ABC, CBS, NBC and Fox) to commence DTV broadcasts in the top ten
markets by May 1999 and in the top 30 markets by November 1999. In the United
Kingdom, pursuant to the Broadcasting Act 1996, six digital television
transmission multiplexes, which permit the holders to transmit digital
television broadcasting services, have been allocated. The Company successfully
began commercial operation of the DTT network from an initial 22 transmission
sites on November 15, 1998. Australia, France, Germany, Japan, Spain and Sweden
are expected to be the next countries to introduce digital terrestrial
television, followed by other European nations and later by developing
countries. Many countries are expected to start to establish digital services
within the next five years. The shift to digital transmission will require
network design, development and engineering services and the significant
enhancement of existing broadcast transmission infrastructure, including new
transmission and monitoring equipment and the modification, strengthening and
construction of towers (including over 1,000 tall towers in the United States).
In addition, state-run broadcast transmission networks are continuing to be
privatized throughout the world.

The Company expects these trends to continue around the world in both the
wireless communications and broadcasting industries. The Company believes that
the next logical step in the outsourcing of infrastructure by wireless carriers
and broadcasters will be the outsourcing of the

65
<PAGE>

operation of their towers and transmission networks, including the transmission
of their signals, in much the same way as the BBC has done with its
transmission network. This outsourcing will allow carriers to realize
additional operating and capital efficiencies and to focus on management of
their customer bases and expansion of their service offerings. Management
believes that such carriers will only entrust the transmission of their signals
to those infrastructure providers, such as the Company, that have the ability
to manage towers and transmission networks and a proven track record of
providing end-to-end services to the wireless communications and broadcasting
industries.

Development of the Tower Industry

United States. The U.S. wireless communications industry was transformed in
the 1970s through the issuance of licenses by the FCC to provide high quality
communications services to vehicle-mounted and hand-held portable telephones,
pagers and other devices. The licensees built and began operating wireless
networks that were supported by communication sites, transmission equipment and
other infrastructure. In the early 1980s, the number of towers began to expand
significantly with the development of more advanced wireless communications
systems, particularly cellular and paging. Nevertheless, as additional towers
were built by the wireless carriers, they often were built for a single purpose
rather than as multiple tenant towers. Further, these towers were generally
owned and maintained by carriers and were treated as corporate cost centers
operated primarily for the purpose of transmitting or receiving such carriers'
signals.

During the mid-to-late 1980s, a number of independent operators of towers
began to emerge. These independent tower operators focused on owning and
managing towers with multiple tenants by adding lessees to existing and
reconstructed towers. The Company believes the majority of these operators were
small business owners with a small number of local towers and few services
other than site rental. In the last five years, however, several larger
independent tower operators have emerged as demand for wireless services has
continued to grow and as additional high frequency licenses have been awarded
for new wireless services (including PCS, narrowband paging and wireless local
loop), each requiring networks with extensive tower infrastructure. These
independent tower operators have sought to acquire smaller operators as well as
suitable clusters of towers formerly owned by carriers and broadcasters in
order to establish regional and national "tower footprints". Carriers expanding
or building a network in a geographic area generally seek to lease space for
antennas from a tower company with a strategically located cluster of towers
and other communication sites in that area in order to efficiently and
effectively establish service coverage in a given market.

Today, towers are owned by a variety of companies, including wireless
carriers, local and long distance telecommunications companies, broadcasting
companies, independent tower operators, utilities and railroad companies.
Despite the increasing demand for towers, the tower industry in the United
States remains highly fragmented, with only a few independent tower operators
owning a large number of towers. The pace of consolidation has begun to
accelerate, however, as the larger independent operators continue to acquire
small local operators and purchase towers from wireless communications
companies. In addition, wireless carriers are building out new, or filling in
existing, tower footprints for new and existing wireless services. Independent
operators have also expanded into a number of associated network and
communication site services, including the design of communication sites and
networks, the selection and acquisition of tower and rooftop sites (including
the resolution of zoning and permitting issues) and the construction of towers.
Previously, carriers typically handled such services through in-house
departments, and local nonintegrated service contractors focused on specific
segments such as radio frequency engineering and site acquisition.

Broadcast towers in the United States have typically been owned and
operated on a fragmented basis. Typically, each network affiliate in each major
market owns and operates its own television broadcasting tower. Local stations
often have co-located their transmission equipment on these towers. Radio
broadcast towers have also typically been erected by each station in a given

66
<PAGE>

market. Both television and radio broadcast towers have generally been
constructed only for a single user and would require substantial strengthening
to house new digital transmission equipment or other analog transmission
equipment. As a result, similar to wireless communications towers, such towers
historically have been treated as corporate cost centers operated primarily for
the purpose of transmitting such broadcasters' signals.

United Kingdom. The first towers in the United Kingdom were built for the
BBC's MF radio services. Additional towers were built in the 1940s to transmit
HF radio services around the world. In the 1950s, both the BBC and Independent
Television Authority (the predecessor of the Independent Broadcasting
Authority) built towers for transmission of VHF television. The BBC used some
of these towers and built additional towers in the 1960s for its VHF/FM radio
services. UHF television started in 1964 and is now transmitted from some 1,100
towers. These towers have been built at a relatively constant rate (compared
with wireless communications towers). The majority of tall towers were built in
the 1950s and 1960s. The number of smaller towers built peaked at approximately
80 per year in the 1970s, reducing to approximately 25 per year in the early
1990s. The size and structure of towers varies widely due to location, antenna
requirements and wind loading. Towers built primarily for broadcast
transmission are often able to carry wireless communications antennas. Those
that are currently incapable of doing so can be strengthened or replaced.

Since 1982, the growth of wireless communications in the United Kingdom has
led to significant expansion in the number of towers. Historically, there have
been four major wireless carriers in the United Kingdom, each of which, in
general, built towers for its own use, rather than as multiple tenant owners.
These towers are owned and maintained by such carriers and, as in the United
States, were treated as corporate cost centers operated primarily for the
purpose of transmitting or receiving their signals. With the smaller geographic
size of the United Kingdom, as compared to the United States, these carriers
typically constructed their tower footprint to provide national coverage.
Because of this nationwide build out, independent tower owners have not
developed as they have in the United States. In addition to wireless
communications providers, towers in the United Kingdom are owned by a variety
of companies, such as telecommunications companies, utilities and railroad
companies.

Today, tower owners are upgrading their networks to provide more capacity
and better service to their customers, while new entrants to the wireless
communications market have sought to acquire rapid access to networks that
provide national coverage. With the significant costs associated with the
approval process for and the construction of new towers, and the significant
capital requirements associated with ownership of tower infrastructure,
wireless carriers have begun to look to third party tower owners to co-locate
their antennas on existing towers, to build, own and operate new towers and to
acquire such carriers' portfolios of existing towers.

Characteristics of the Tower Industry

Management believes that, in addition to the favorable growth and
outsourcing trends in the wireless communications and broadcasting industries
and high barriers to entry as a result of regulatory and local zoning
restrictions associated with new tower sites, tower operators benefit from
several favorable characteristics. The ability of tower operators to provide
antenna sites to customers on multiple tenant towers provides them with
diversification against the specific technology, product and market risks
typically faced by any individual carrier. The emergence of new technologies,
carriers, products and markets may allow independent tower operators to further
diversify against such risks. Additionally, tower operators face increased
"Not-In-My-Backyard" ("NIMBY") sentiment by communities and municipalities,
which is reducing the number of opportunities for new towers to be built and
driving the trend toward co-location on multiple tenant towers.

The Company believes that independent tower operators also benefit from the
contractual nature of the site rental business and the predictability and
stability of monthly, recurring revenues. In addition, the site rental business
has low variable costs and significant operating leverage. Towers

67
<PAGE>

generally are fixed cost assets with minimal variable costs associated with
additional tenants. A tower operator can generally expect to experience
increasing operating margins when new tenants are added to existing towers.

The site rental business typically experiences low tenant churn as a result
of the high costs that would be incurred by a wireless communications carrier
were it to relocate an antenna to another site and consequently be forced to
re-engineer its network. Moving a single antenna may alter the pre-engineered
maximum signal coverage, requiring a reconfigured network at significant cost
to maintain the same coverage. Similarly, a television or FM broadcaster would
incur significant costs were it to relocate a transmitter because, in order to
avoid interruption of its transmissions, it would be necessary for the
broadcaster to install and commence operations of a second broadcast site prior
to ceasing signal transmission at the first site. In addition, regulatory
problems associated with licensing the location of the new antenna with the
FCC, in the United States, or being licensed for the location by the
Radiocommunications Agency (the "RA") in the United Kingdom, may arise if the
new location is at the edge of the wireless communication carrier's coverage
area and if there is a possible adverse impact on other carriers. Municipal
approvals are becoming increasingly difficult to obtain and may also affect the
carrier's decision to relocate. The costs associated with network
reconfiguration and FCC, RA and municipal approval and the time required to
complete these activities may not be justified by any potential savings in
reduced site rental expense.

Trends in the Wireless Communications and Broadcasting Industries

The Company's existing and future business opportunities are affected by
the ongoing trends within the two major industries it serves, namely the
wireless communications industry and the radio and television broadcasting
industry. Each of these industries is currently experiencing a period of
significant change that the Company believes is creating an increasing demand
for communication sites and related infrastructure and network support
services.

Wireless Communications

The wireless communications industry now provides a broad range of
services, including cellular, PCS, paging and SMR. The industry has benefitted
in recent years from increasing demand for its services, and industry experts
expect this demand to continue to increase.

The Company believes that more communication sites will be required in the
future to accommodate the expected increase in demand for wireless
communications services. Further, the Company sees additional opportunities
with the development of higher frequency technologies (such as PCS), which have
a reduced cell range as a result of signal propagation characteristics that
require a more dense network of towers. In addition, network services may be
required to service the network build-outs of new carriers and the network
upgrades and expansion of existing carriers.

In addition to the increasing demand for wireless services and the need to
develop and expand wireless communications networks, the Company believes that
other trends influencing the wireless communication industry have important
implications for independent tower operators. In order to speed new network
deployment or expansion and generate efficiencies, carriers are increasingly
co-locating transmission equipment with that of other network operators. The
trend towards co-location has been furthered by the NIMBY arguments generated
by local zoning/planning authorities in opposition to the proliferation of
towers. Further, the number of competitors in wireless communications is
increasing due to the auction of new spectrum and the deployment of new
technologies. In this increasingly competitive environment, many carriers are
dedicating their capital and operations primarily to those activities that
directly contribute to subscriber growth, such as marketing and distribution.
These carriers, therefore, have sought to reduce costs and increase efficiency
through the outsourcing of infrastructure network functions such as
communication site ownership, construction, operation and maintenance. Further,
the Company believes that these

68
<PAGE>

carriers are beginning to seek to move their tower portfolios off their balance
sheets through sales to, or joint ventures with, experienced tower operators
who have the proven capability to provide end-to-end services to the wireless
communications industry.

United States. Current emerging wireless communications systems, such as
PCS and SMR, represent an immediate and sizable market for independent tower
operators and network services providers as carriers build out large nationwide
and regional networks. While several PCS and SMR carriers have already built
limited networks in certain markets, these carriers still need to fill in "dead
zones" and expand geographic coverage. The Cellular Telecommunications Industry
Association ("CTIA") estimates that, as of June 1998, there were 57,674 antenna
sites in the United States. The Personal Communications Industry Association
("PCIA") estimates that the wireless communications industry will construct at
least 100,000 new antenna sites over the next 10 years. As a result of advances
in digital technology, SMR operators, including Nextel, have also begun to
design and deploy digital mobile telecommunications networks in competition
with cellular carriers. In particular response to the increased competition,
cellular operators are re-engineering their networks by increasing the number
of sites, locating sites within a smaller radius, filling in "dead zones" and
converting from analog to digital cellular service in order to manage
subscriber growth, extend geographic coverage and provide competitive services.
The demand for communication sites is also being stimulated by the development
of new paging applications, such as e-mail and voicemail notification and two-
way paging, as well as other wireless data applications. In addition, as
wireless communications networks expand and new networks are deployed, the
Company anticipates that demand for microwave transmission facilities that
provide "backhaul" of traffic between communications sites to or from a central
switching facility will also increase.

Licenses are also being awarded, and technologies are being developed, for
numerous new wireless applications that will require networks of communication
sites. Future potential applications include those that will be deployed by the
winners of licenses auctioned in February and March 1998 for local multi-point
distribution services, including wireless local loop, wireless cable
television, wireless data and wireless Internet access, as well as forthcoming
auctions for PCS and local multi-point distribution services. Radio spectrum
required for these technologies has, in many cases, already been awarded and
licensees have begun to build out and offer services through new wireless
systems. Examples of these systems include local loop networks operated by
WinStar and Teligent, wireless cable networks operated by companies such as
Cellular Vision and CAI Wireless, and data networks being constructed and
operated by RAM Mobile Data, MTEL and Ardis.

United Kingdom. As in the United States, the development of newer wireless
communications technologies, such as PCN and digital Terrestrial Trunked Radio
("TETRA"), provides tower operators with immediate opportunities for site
rental and new tower build out. The four existing national GSM/PCN carriers
continue to fill in "dead zones" and add capacity to their networks. Also, the
carrier that is using the TETRA standard, which is similar to GSM and has been
adopted throughout Europe, is deploying a network across the United Kingdom.
The United Kingdom's newly-licensed wireless local loop operators have the
potential to be important site rental customers. Wireless local loop operators
provide telephony services that are comparable to the range and quality of
services delivered over the fixed wire networks. This technology is being
rapidly deployed as a low-cost alternative to fixed networks. To date, a total
of seven spectrum licenses have been awarded to companies planning to deploy
wireless loop systems. In addition, the deployment of a new national digital
PMR system (using the TETRA standard) for the use of the U.K. emergency
services and the announced licensing in early 1999 by the U.K. Government of
UMTS (Universal Mobile Telecommunications Service) networks, which will be the
third generation of cellular, should create additional demand for antenna space
and tower sites.

Radio and Television Broadcasting

General. There are currently three main transmission delivery methods for
television and radio broadcasts: terrestrial, direct-to-home ("DTH") satellite
and cable. Terrestrial technology, the most

69
<PAGE>

common delivery method in the United States and many other countries including
the United Kingdom, relies on signal transmission by wireless telegraphy from a
network of terrestrial transmitters for direct reception by viewers or
listeners through an aerial system. Satellite signals are transmitted to
satellites that then beam the signal over a target area (satellite footprint)
for reception by a customer's satellite dish. A satellite customer must either
purchase or rent a dish and a receiver/decoder and pay subscription fees to the
relevant provider. A cable television customer typically rents a
receiver/decoder and pays a subscription fee to receive services that are
distributed to the home through co-axial or fiber optic cable.

Until the 1990s, all three delivery methods used analog technology, which
remains the most widespread technology in use today. In the early 1990s,
digital technology was developed for radio and television broadcasting and has
begun to be introduced for the transmission of radio and television signals.
Digital transmission is now possible by terrestrial, satellite and cable
methods.

Digital technology allows a number of signals to be compressed and
interleaved, using a technical process called "multiplexing", before the
combined signal is transmitted within a single frequency channel. This process
makes the signal more robust, allowing the use of parts of the spectrum
unavailable to analog. A greater quantity of audio-visual information can be
transmitted with the same amount of frequency spectrum allowing higher
resolution or multiple channels to be broadcast. At the point of reception, the
compression and interleaving are decoded and individual signals recovered.

Some of the principal advantages of digital compared to analog transmission
include: (1) greater number, choice and flexibility of broadcasting services
offered; (2) scope for greater interactivity on the part of viewers and
listeners; (3) greater capacity for pay-television (subscription and pay-per-
view) as well as free-to-air services; and (4) enhanced picture quality and
sound. The development and timing of implementation of digital transmission
technology to the general public is a function of several factors, including
technological advancement, cost of equipment and conversion process, quality
improvement of visual and sound transmission and demand for terrestrial
bandwidth. The transition to digital transmission will involve additional costs
to viewers and program and transmission service providers. Viewers will require
additional equipment such as set-top boxes or digital televisions. Program
providers have begun to re-equip their studios and production facilities with
digital technology.

United States. Prior to the introduction of digital transmission, the U.S.
broadcasting industry had generally been a mature one in terms of demand for
transmission tower capacity, although even then opportunities existed for
independent tower operators to purchase transmission networks, manage them on
behalf of broadcasters under long-term contracts and lease space on
broadcasting towers to wireless carriers.

The FCC-mandated introduction of digital television broadcasting will
provide new opportunities for independent tower operators. The conversion of
broadcasting systems from analog to digital technology will require a
substantial number of new towers to be constructed to accommodate the new
systems and analog equipment displaced from existing towers. Even with DTV
transmissions, television station owners will continue to broadcast the
existing analog signals for a number of years. Broadcasters that own their own
tower infrastructure may elect to remove third-party tenants from their towers
to make room for their own DTV equipment. These displaced tenants, and tower
owners that are unable to remove existing third party tenants from their
towers, will require new towers to accommodate their transmission equipment.
The National Association of Broadcasters projects that by the year 2010
approximately 1,400 tall towers will be required to be built, strengthened or
modified to support DTV, with 200 towers required in the top 50 markets within
the next five years. Further, because of the need for broadcasters to purchase
new transmission equipment to deploy DTV, they will have fewer resources to
devote to the build out of new tower infrastructure. The Company believes that
these circumstances, along with the relative scarcity of suitable sites and

70
<PAGE>

prevalent NIMBY attitudes, will allow experienced tower operators to build and
operate multiple tenant broadcast towers to transmit DTV signals. These towers
will also be attractive sites for the distribution of FM radio broadcasts.

United Kingdom. The broadcasting industry in the United Kingdom has
generally been a mature one in terms of demand for transmission tower capacity.
Existing towers provide almost universal coverage for analog transmission,
which remains the primary mode of transmission for television and radio
programs in the United Kingdom. Most of the BBC's radio services, three
Independent National Radio services and many local services are broadcast by
analog terrestrial means. Some radio services are also available by satellite
and cable for reception on fixed installations, but not portable or mobile
sets.

Digital television services in the United Kingdom were launched in 1998
from terrestrial transmitters (DTT) and satellite (DST). The Broadcasting Act
of 1996 sets out a framework for the licensing of digital terrestrial
multiplexes and an industry interest group has been established to coordinate
the establishment of digital television in the United Kingdom. The British
Government has allocated six multiplexes for DTT: two and one-half of these
multiplexes were reserved for the BBC, ITV, Channel 4, S4C and Channel 5, three
were awarded to ONdigital (which is a joint venture of Carlton Communications
PLC and Granada Group PLC) and the other one-half was awarded to S4C Digital
Network. The Company has been awarded the digital transmission contract for the
four multiplexes held by the BBC and ONdigital, while NTL has been awarded the
digital transmission contract for the other two multiplexes.

Build-out of digital terrestrial transmission equipment in the United
Kingdom is being based on existing analog terrestrial infrastructure, including
transmission sites and towers. In the initial phase of the rollout of digital
terrestrial transmission equipment, 81 analog transmission sites and towers
will be upgraded with new transmitters and associated systems required to
support DTT. Digital broadcasts from these sites are expected to reach
approximately 90% of the U.K. population. It is expected that additional sites
will continue to be upgraded until the "vast majority" of viewers can receive
digital broadcasts.

While no formal timetable has been set for the discontinuation of analog
terrestrial television broadcasting, the British Government has announced its
intention to review, by 2002, the timing of analog "switch-off". When analog
television transmission ceases, large amounts of frequency spectrum will be
released. New uses for this spectrum have not yet been defined but applications
are likely to include other digital broadcasting applications and mobile
communications. The spectrum is inherently suitable for terrestrial
transmission, so it is likely that existing towers will be used to provide many
of the new services.

In September 1995, the BBC launched the United Kingdom's first digital
radio service, which is now broadcast to approximately 60% of the U.K.
population from 29 transmission sites. Independent Local Radio licenses for
additional digital radio multiplexes are expected to be issued by the end of
1999.

To date, existing broadcast towers have been used as transmission sites for
the BBC's digital radio service, and it is anticipated that existing towers
also will be used for the independent services, often sharing the antennas used
for the BBC's digital radio service. While digital radio has the advantage of
using a single frequency network, which enables expanded geographic coverage as
compared with the multiple frequency networks used for analog radio, to
replicate the coverage of analog radio it will be necessary to broadcast
digital radio from more sites than at present. Although detailed planning has
not yet begun, it is expected that existing towers will provide the necessary
sites. As with DTT, the Company believes that ownership of key broadcasting
sites across the United Kingdom will allow an experienced operator to provide
the infrastructure necessary to accommodate the growth in digital radio at
minimum cost.

BUSINESS

We are a leading owner and operator of wireless communications and
broadcast transmission infrastructure. After giving effect to the completion of
the Proposed Transactions, as of December 31, 1998, we owned or managed 6,105
towers, including 4,419 towers in the United States and Puerto Rico and 1,686
towers in the United Kingdom. Our customers currently include many of the
world's major wireless communications and broadcast companies, including BAM,
BellSouth, AT&T Wireless, Nextel and the BBC.

Our strategy is to use our leading domestic and international position to
capture the growing consolidation and build-out opportunities created by:

. the outsourcing of towers by major wireless carriers;
. the need for existing wireless carriers to expand coverage and improve
capacity;
. the additional demand for towers created by new entrants into the
wireless communications industry;
. the privatization of state-run broadcast transmission networks; and
. the introduction of new digital broadcast transmission technology and
wireless technologies.

Our primary business in the United States is the leasing of antenna space
to wireless operators under long-term contracts. After completion of the
proposed transactions we describe in this prospectus, we will have tower
clusters in 26 of the 50 largest U.S. metropolitan areas, including 23
metropolitan areas east of the Mississippi river. We believe that by owning and
managing large tower clusters we are able to offer customers the ability to
fulfill rapidly and efficiently their network expansion plans across particular
markets or regions. Our acquisition strategy has been focused on adding tower
clusters. For example, we have entered into agreements with BAM and BellSouth
that will allow us to control and operate substantially all the towers in their
850 MHz networks in the eastern, southwestern and midwestern United States.

Our primary business in the United Kingdom is the operation of television
and radio broadcast transmission networks. Our towers provide broadcast
coverage to 99% of the population and substantially all of the major
metropolitan markets. In 1997, we acquired the BBC's national broadcast
transmission infrastructure and network services. Following the acquisition of
the BBC's tower infrastructure, we were awarded long-term contracts to provide
the BBC and other broadcasters analog and digital transmission services. We
also lease antenna space to wireless operators in the United Kingdom on the
towers we acquired from the BBC and from various wireless carriers. We believe
that these broadcast towers are uniquely situated in locations that wireless
carriers seeking to lease antenna space find particularly desirable.

72
<PAGE>

We have embarked on a major construction program for our customers to
enhance our tower footprint. In 1998, we constructed 231 towers at an aggregate
cost of approximately $46.0 million, and had begun construction of an
additional 72 towers as of December 31, 1998. In 1999, we plan to construct
between 800 and 1,100 towers at an estimated aggregate cost between $150.0
million and $200.0 million for wireless carriers such as BAM, BellSouth and
Nextel. The actual number of towers built may be outside that range depending
on acquisition opportunities and potential build-to-suit contracts from large
wireless carriers. In addition, we were selected to build and operate the
world's first digital terrestrial television system in the United Kingdom based
on our broadcast engineering expertise.

Growth Strategy

Our objective is to become the premier global provider of wireless
communications and broadcast transmission infrastructure and related services.
Our experience in establishing and expanding our existing tower footprints, our
experience in owning and operating both analog and digital transmission
networks, our significant relationships with wireless carriers and broadcasters
and our ability to offer customers our in-house technical and operational
expertise, uniquely position us to capitalize on global growth opportunities.
The key elements of our business strategy are to:

. Maximize Utilization of Tower Capacity. We are seeking to take advantage
of the substantial operating leverage of our site rental business by
increasing the number of antenna leases on our owned and managed
communications sites. We believe that many of our towers have
significant capacity available for additional antenna space rental and
that increased utilization of our tower capacity can be achieved at low
incremental cost. For example, prior to our purchase of the BBC's
broadcast transmission network in 1997, the rental of available antenna
capacity on the BBC's premier tower sites was not actively marketed to
third parties. We believe there is substantial demand for such capacity.
In addition, we believe that the extra capacity on our tower footprints
in the United States and the United Kingdom will be highly desirable to
new entrants into the wireless communications industry. Such carriers
are able to launch service quickly and relatively inexpensively by
designing the deployment of their networks based on our attractive
existing tower footprints. Further, we intend to selectively build and
acquire additional towers to improve the coverage of our existing tower
footprints to further increase their attractiveness. We intend to use
targeted sales and marketing techniques to increase utilization of and
investment return on our existing, newly constructed and acquired
towers.

. Leverage Expertise of U.S. and U.K. Personnel to Capture Global Growth
Strategy. We are seeking to leverage the skills of our personnel in the
United States and the United Kingdom. We believe that our ability to
manage networks, including the transmission of signals, will be an
important competitive advantage in our pursuit of global growth
opportunities, as evidenced by the BBC, One2One, BAM, BellSouth and
Powertel transactions. With our wireless communications and broadcast
transmission network design and radio frequency engineering expertise,
we are well positioned (1) to partner with major wireless carriers to
assume ownership of their existing towers, (2) to provide build-to-suit
towers for wireless carriers and broadcasters and (3) to acquire
existing broadcast transmission networks that are being privatized
around the world.

. Partner with Wireless Carriers to Assume Ownership of their Existing
Towers. In addition to the proposed joint venture with BAM and the
transaction with BellSouth, we are continuing to seek to partner with
other major wireless carriers to assume ownership of their existing
towers directly or through joint ventures or control their towers
through contractual arrangements. We believe the primary criteria of
such carriers in selecting a company to own and operate their wireless
communications infrastructure will be the company's perceived capability
to maintain the integrity of their networks, including their
transmission

73
<PAGE>

signals. Therefore, we believe that those companies with a proven track
record of providing end-to-end services will be best positioned to
successfully acquire access to such wireless communications
infrastructure. We believe that similar opportunities will arise
globally as the wireless communications industry further expands.

. Provide Build-to-Suit Towers for Wireless Carriers and Broadcasters. As
wireless carriers continue to expand and fill-in their service areas,
they will require additional communications sites and will have to build
new towers where co-location is not available. Similarly, the
introduction of digital terrestrial television broadcasting in the
United States will require the construction of new broadcast towers to
accommodate new digital transmission equipment and analog transmission
equipment displaced from existing towers. We are aggressively pursuing
these build-to-suit opportunities, leveraging on our ability to offer
end-to-end services.

. Acquire Existing Broadcast Transmission Networks. In 1997, CTI
successfully acquired the privatized domestic broadcast transmission
network of the BBC. In addition, we are implementing the roll-out of
digital television transmission services throughout the United Kingdom.
As a result of this experience, we are well positioned to acquire other
state-owned analog and digital broadcast transmission networks globally
when opportunities arise. These state-owned broadcast transmission
networks typically enjoy premier sites giving an acquirer the ability to
offer unused antenna capacity to new and existing radio and television
broadcasters and wireless carriers, as well as to install new
technologies such as digital terrestrial transmission services. In
addition, our experience in broadcast transmission services allows us to
consider, when attractive opportunities arise, acquiring wireless
transmission networks as well as the acquisition of associated wireless
communications infrastructure. We are currently pursuing international
acquisition and privatization opportunities, including a bid in
connection with the state-run auction of Australia's National
Transmission Network.

. Continue to Decentralize Management Functions. In order to better manage
our tower lease-up efforts and build-out programs, and in anticipation
of the continued growth of our tower footprints throughout the United
States, we have begun and plan to continue decentralizing some
management and operational functions. To that end, in addition to our
Pittsburgh operating headquarters and regional office, we have opened
and staffed five regional offices, including Houston, Louisville,
Phoenix, Albany and Puerto Rico. Upon consummation of the Proposed
Transactions we plan to open 10 additional regional offices, five in
connection with the Proposed BAM JV, three in connection with the
Proposed BellSouth Transaction and two in connection with the Proposed
Powertel Acquisition. The principal responsibilities of these offices
are to manage the leasing of tower space on a regional basis through a
dedicated local sales force, to maintain the towers already located in
the region and to implement our build-to-suit commitments in the area.
We believe that by moving a significant amount of our operating
personnel to regional offices we will be better able to strengthen our
relationship with regional carriers, serve our customers more
effectively and identify additional build-to-suit opportunities with
local and regional carriers.

U.S. Operations

Overview

Our primary business focus in the United States is the leasing of antenna
space on multiple tenant towers and rooftops to a variety of wireless carriers
under long-term lease contracts. Supporting our competitive position in the
site rental business, we maintain in-house expertise in, and offer our
customers, infrastructure and network support services that include network
design and communication site selection, site acquisition, site development and
construction and antenna installation.

We lease antenna space to our customers on our owned and managed towers. We
generally receive fees for installing customers' equipment and antennas on a
tower and also receive monthly rental payments from customers payable under
site rental leases that generally range in length from three to five years. Our
U.S. customers include such companies as AT&T Wireless, Aerial Communications,
AirTouch Cellular, Arch Communications, Bell Atlantic Mobile, BellSouth
Mobility, Cellular One, Federal Express, Lucent Technologies, Motorola, Nextel,
Nokia, PageNet, Skytel, Sprint PCS and TSR Wireless, as well as private network
operators and various federal and local government agencies, such as the FBI,
the IRS and the U.S. Postal Service.

At December 31, 1998, without giving effect to the Proposed Transactions,
we owned or managed 609 towers and 78 rooftop sites in the United States and
Puerto Rico. These towers and rooftop sites are located in western Pennsylvania
(primarily in and around the greater Pittsburgh area), in the southwestern
United States (primarily in western Texas), across Puerto Rico and along I-95
in North Carolina and South Carolina.

Upon completion of the Proposed BAM JV, the joint venture will control and
operate approximately 1,427 towers. These towers represent substantially all
the towers in BAM's 850 MHz wireless network in the eastern and southwestern
United States and provide coverage of 11 of the top 50 U.S. metropolitan areas
including New York, Philadelphia, Boston, Washington, D.C. and Phoenix. A
substantial majority of these towers are over 100 feet tall and can accommodate
multiple tenants.

After consummation of the Proposed BellSouth Transaction, we will control
and operate 1,850 towers. These towers represent substantially all the towers
in BellSouth's 850 MHZ wireless network in the southeastern and midwestern
United States and provide coverage of 12 of the top 50 U.S. metropolitan areas,
including Miami, Atlanta, Tampa, Nashville and Indianapolis. A substantial
majority of these towers are over 100 feet tall and can accommodate multiple
tenants.

Upon completion of the Proposed Powertel Acquisition, we will own and
operate an additional 650 towers. These towers represent substantially all of
Powertel's owned towers in its 1.9 GHz wireless

76
<PAGE>

network in the southeastern and midwestern United States. Approximately 90% of
these towers are clustered in seven southeastern states providing coverage of
such metropolitan areas as Atlanta, Birmingham, Jacksonville, Memphis and
Louisville, and a number of major connecting highway corridors in the
Southeast. These towers are complementary to BellSouth's 850 MHZ footprint in
the southeast and have minimal coverage overlap. Substantially all of these
towers are over 100 feet tall, were built within the last three years and can
such accommodate multiple tenants.

We are actively seeking to enter into arrangements with other major
wireless carriers and independent tower operators to acquire additional tower
footprints. We believe that, like BAM, BellSouth and Powertel, other wireless
carriers will seek to enter into contractual arrangements with independent
tower carriers, such as us, for the ownership or control of their tower
footprints.

We also plan to leverage CCI's network design expertise to construct new
towers. We plan to build towers in areas where carriers' signals fail to
transmit in their coverage area. The areas, commonly known as "dead zones", are
attractive tower locations. When population density and perceived demand are
such that we believe the economics of constructing such towers are justified,
we build towers that can accommodate multiple tenants. The multiple tenant
design of these towers obviates the need for expensive and time consuming
modifications to upgrade undersized towers, saving critical capital and time
for carriers facing time-to-market constraints. The towers are also designed to
easily add additional customers, and the equipment shelters are built to
accommodate another floor for new equipment and air conditioning units when
additional capacity is needed. The tower site is zoned for multiple carriers at
the time the tower is constructed to allow new carriers to quickly utilize the
site. In addition, the towers, equipment shelters and site compounds are
engineered to protect and maintain the structural integrity of the site.

Our existing build-to-suit contracts include an agreement with Nextel,
under which we have already constructed 67 sites and have an option to
construct up to 96 additional sites. In connection with the Proposed BAM JV,
BAM and the joint venture will enter into a master build-to-suit agreement
pursuant to which the joint venture will build and own the next 500 towers to
be built for BAM's wireless communications business over the next five years.
Further, we have agreed to enter into a build-to-suit agreement with BellSouth,
as part of the Proposed BellSouth Transaction, to construct at least 500 towers
on behalf of BellSouth in the region covered by that transaction over the next
five years. See "The Proposed Transactions--The Proposed BAM JV--Build to Suit
Agreement" and "--The Proposed BellSouth Transaction--Build to Suit Agreement".

Site Rental

In the United States, we rent antenna space on our owned and managed towers
and rooftops to a variety of carriers operating cellular, PCS, SMR, ESMR,
paging and other networks.

Tower Site Rental. We lease space to our customers on our owned and managed
towers. We generally receive fees for installing customers' equipment and
antennas on a tower (as provided in our network services programs) and also
receive monthly rental payments from customers payable under site leases. In
the United States, the majority of our outstanding customer leases, and the new
leases typically entered into by us, have original terms of five years (with
three or four optional renewal periods of five years each) and provide for
annual price increases based on the Consumer Price Index.

77
<PAGE>

We also provide a range of site maintenance services in order to support
and enhance our site rental business. We believe that by offering services such
as antenna, base station and tower maintenance and security monitoring, we are
able to offer quality services to retain our existing customers and attract
future customers to our communication sites. We were the first site management
company in the United States selected by a major wireless carrier to
exclusively manage its tower network and market the network to other carriers
for co-location.

The following table describes, without giving effect to the Proposed
Transactions, our top ten revenue producing towers in the United States and
Puerto Rico:

</TABLE>

We have existing master lease agreements with AT&T Wireless, Aerial
Communications, BAM, Nextel and Sprint PCS, among others, which provide certain
terms (including economic terms) that govern new leases entered into by such
parties during the term of their master lease agreements, including the lease
of space on towers in the Pittsburgh major trading area ("Pittsburgh MTA"),
which includes greater Pittsburgh and parts of Ohio, West Virginia and western
Pennsylvania. Each of the Aerial Communications and Sprint PCS agreements has a
10-year master lease term through December 2006, with one 10-year and one five-
year renewal period. Rents are adjusted periodically based on the cumulative
Consumer Price Index. Nextel's master lease agreement with the Company has a
10-year master lease term through October 2006, with two 10-year renewal
options. We have also entered into an independent contractor agreement with
Nextel. The BAM agreement has a 25-year master lease term through December
2020.

We have significant site rental opportunities arising out of our existing
agreements with BAM and Nextel. In our existing lease agreement with BAM, we
have exclusive leasing rights for 117 existing towers and we currently have
sublessees on 58 of these towers in the greater Pittsburgh area. The lease
agreement provides that CCI may sublet space on any of these towers to another
carrier subject to certain approval rights of BAM. To date, BAM has never
failed to approve a sublease proposed by CCI. If the Proposed BAM JV is formed,
it is expected that these 117 towers will be among the 1,427 towers to be
contributed to the joint venture by BAM. Because we would maintain the right to
put sublessees on those 117 towers, revenue resulting from the addition of new
tenants on those towers would continue to be realized by us rather than the
joint venture. In connection with the Nextel Agreement, as of December 31,
1998, we have the option to own and operate up to 96 additional towers.

We will also enter into master lease agreements and have significant site
rental opportunities in connection with the Proposed Transactions. In
connection with the Proposed BAM JV we will enter into a global lease under
which BAM will lease antenna space on the towers transferred to the joint

78
<PAGE>

venture, as well as the towers built pursuant to the build-to-suit agreement.
In connection with the Proposed BellSouth Transaction, we will be paid a
monthly site maintenance fee from BellSouth for its use of space on the towers
we control. We will also enter into a master lease agreement with the sellers
in the Proposed Powertel Acquisition pursuant to which the sellers will rent
space on the acquired towers. In each of the Proposed Transactions, we will be
permitted to lease additional space on the towers to third parties. See "The
Proposed Transactions".

Rooftop Site Rental. We are a leading rooftop site management company in
the United States. Through our subsidiary, Spectrum, we develop new sources of
revenue for building owners by effectively managing all technical aspects of
rooftop telecommunications, including two-way radio systems, microwave
facilities, fiber optics, wireless cable, paging, rooftop infrastructure
services and optimization of equipment location. We also handle billing and
collections and all calls and questions regarding the site, totally relieving
the building's management of this responsibility. In addition to the technical
aspects of site management, we provide operational support for both wireless
carriers looking to build out their wireless networks, and building owners
seeking to out source their site rental activities. We generally enter into
management agreements with building owners and receive a percentage of the
revenues generated from the tenant license agreements.

Network Services

We design, build and operate our own communication sites. Through CCI, we
have developed an in-house expertise in certain value-added services that we
offer to the wireless communications and broadcasting industries. Because we
view CCI as a turn-key provider with "end-to-end" design, construction and
operating expertise, we offer our customers the flexibility of choosing between
the provision of a full ready-to-operate network infrastructure or any of the
component services involved therein. Such services include network design and
site selection, site acquisition, site development and construction and antenna
installation.

Network Design and Site Selection. We have extensive experience in network
design and engineering and site selection. While we maintain sophisticated
network design services primarily to support the location and construction of
Company-owned multiple tenant towers, we do from time to time provide network
design and site selection services to carriers and other customers on a
consulting contract basis. Our network design and site selection services
provide our customers with relevant information, including recommendations
regarding location and height of towers, appropriate types of antennas,
transmission power and frequency selection and related fixed network
considerations. In 1998, we provided network design services primarily for our
own footprints and also for certain customers, including Triton Communications,
Nextel, Aerial Communications and Sprint PCS. These customers were typically
charged on a time and materials basis.

To capitalize on the growing concerns over tower proliferation, we have
developed a program called "Network Solutions" through which we will attempt to
form strategic alliances with local governments to create a single
communications network in their communities. To date our efforts have focused
on western Pennsylvania, where we have formed alliances with three
municipalities. These alliances are intended to accommodate wireless carriers
and local public safety, emergency services and municipal services groups as
part of an effort to minimize tower proliferation. By promoting towers designed
for co-location, these alliances will reduce the number of towers in
communities while serving the needs of wireless carriers and wireless
customers.

Site Acquisition. In the United States, we are engaged in site acquisition
services for our own purposes and for third parties. Based on data generated in
the network design and site selection process, a "search ring", generally of a
one-mile radius, is issued to the site acquisition department for verification
of possible land purchase or lease deals within the search ring. Within each
search

79
<PAGE>

ring, Geographic Information Systems ("GIS") specialists select the most
suitable sites, based on demographics, traffic patterns and signal
characteristics. Once a site is selected and the terms of an option to purchase
or lease the site are completed, a survey is prepared and the resulting site
plan is created. The plan is then submitted to the local zoning/planning board
for approval. If the site is approved, our construction department takes over
the process of constructing the site.

We have provided site acquisition services to several customers, including
AT&T Wireless, Aerial Communications, AirTouch Cellular, BAM, BellSouth, GTE
Mobilnet, Nextel, Omnipoint, Pagemart, Sprint PCS and Teligent. These customers
engage us for such site acquisition services on either a fixed price contract
or a time and materials basis.

Site Development and Construction and Antenna Installation. We have
provided site development and construction and antenna installation services to
the U.S. communications industry for over 18 years. We have extensive
experience in the development and construction of tower sites and the
installation of antenna, microwave dishes and electrical and telecommunications
lines. Our site development and construction services include clearing sites,
laying foundations and electrical and telecommunications lines, and
constructing equipment shelters and towers. We have designed and built and
presently maintain tower sites for a number of our wireless communications
customers and a substantial part of our own tower network. We can provide cost-
effective and timely completion of construction projects in part because our
site development personnel are cross-trained in all areas of site development,
construction and antenna installation. A varied inventory of heavy construction
equipment and materials are maintained by us at our 45-acre equipment storage
and handling facility in Pittsburgh, which is used as a staging area for
projects in major cities in the eastern region of the United States. We
generally set prices for each site development or construction service
separately. Customers are billed for these services on a fixed price or time
and materials basis and we may negotiate fees on individual sites or for groups
of sites. We have the capability and expertise to install antenna systems for
our paging, cellular, PCS, SMR, ESMR, microwave and broadcasting customers. As
this service is performed, we use our technical expertise to ensure that there
is no interference with other tenants. We typically bill for our antenna
installation services on a fixed price basis.

Our construction management capabilities reflect Crown's extensive
experience in the construction of networks and towers. For example, Crown was
instrumental in launching networks for Sprint PCS, Nextel and Aerial
Communications in the Pittsburgh MTA. In addition, Crown supplied these
carriers with all project management and engineering services which included
antenna design and interference analyses.

In 1998, we provided site development and construction and antenna
installation services to approximately 33 customers in the United States,
including AT&T Wireless, BAM, Nextel and Sprint PCS.

Broadcast Site Rental and Services

We also provide site rental and related services to customers in the
broadcasting industry in the United States. The launch of DTV in the United
States will require significant expansion and modification of the existing
broadcast infrastructure. Because of the significant cost involved in the
construction or modification of tall towers, along with the large capital
expenditures broadcasters will incur in acquiring digital broadcast equipment,
we believe that the television broadcasting industry, which has historically
been opposed to co-location and third party ownership of broadcast
infrastructure, will seek to outsource tower ownership due to cost constraints.
See "Industry Background".

80
<PAGE>

Our objective is to become a leader in the build out of the approximately
200 tall towers expected to be built in the United States over the next five
years. We believe that our experience in providing digital transmission
services in the United Kingdom will make us an attractive provider of broadcast
services to the major networks and their affiliates. In addition, we will seek
to partner with broadcasters and major station ownership groups that own
property zoned for tall towers, but that lack sufficient resources and
expertise to build a tower. We will then attempt to co-locate on the tower the
transmitters of commercial broadcast television stations and high powered FM
radio stations in that market as well as wireless carriers.

Electronic news gathering ("ENG") systems benefit from the towers and
services offered by the Company. The ENG trucks, often in the form of local
television station news vans with telescoping antennas on their roofs, send
live news transmission back to the studio from the scene of an important event.
Typically, these vans cannot transmit signals beyond about 25 miles. In
addition, if they are shielded from the television transmitter site, they
cannot make the connection even at close range. We have developed an ENG
repeater system that can be used on many of our towers in western Pennsylvania
and expect to develop similar systems in other markets in which we have or
develop tower footprints. This system allows the ENG van to send a signal to
one of our local towers where the signal is retransmitted back to the
television transmitter site. The retransmission of the signal from our tower to
the various television transmitter sites is done via a microwave link. We
charge the station for the ENG receiver system at the top of our tower and also
charge them for the microwave dish they place on our tower. Our ENG customers
are affiliates of the NBC, ABC, CBS and Fox networks.

We also have employees with considerable direct construction experience and
market knowledge in the U.S. broadcasting industry, having worked with numerous
television networks around the United States, and a number of other local
broadcasting companies. We have installed master FM and television systems on
buildings across the country. We have supervised the construction and operation
of the largest master FM antenna facility in the United States and have
engineered and installed two 2,000 foot broadcast towers with master FM
antennas. We believe that this experience may help us negotiate favorable
construction contracts for both tower and rooftop sites, and to gain an
expertise in the complex issues surrounding electronic compatibility and RF
engineering.

Significant Contracts

We have many agreements with telecommunications providers in the United
States, including leases, site management contracts and independent contractor
agreements. We currently have important contracts with, among others, BAM,
Nextel and BellSouth. While these agreements currently are important to us, our
most significant contracts in the U.S. will result from consummation of the
Proposed Transactions. In addition, we are party to a contract with the State
of New York, which we believe to be the first of its kind, to manage all State-
owned real estate for wireless communications purposes for the next 20 years.
This contract includes the rights to more than 16,000 structures and rooftops,
tens of thousands of miles of rights-of-way and millions of acres of State-
owned land.

81
<PAGE>

Customers

In both our site rental and network services businesses, we work with a
number of customers in a variety of businesses including cellular, PCS, ESMR,
paging and broadcasting. We work primarily with large national carriers such as
BAM, BellSouth, Sprint PCS, Nextel and AT&T Wireless. For the year ended
December 31, 1998, no customer in the United States accounted for more than
10.0% of CCI's revenues, other than Nextel, which accounted for approximately
12.5% of CCI's consolidated revenues. Nextel revenues are expected to grow as
we build out Nextel interstate corridor sites.

Sales and Marketing

Our sales and marketing personnel, located in our regional offices, target
carriers expanding their networks, entering new markets, bringing new
technologies to market and requiring maintenance or add-on business. All types
of wireless carriers are targeted including broadcast, cellular, paging, PCS,
microwave and two-way radio. We are also interested in attracting 9-1-1,
federal, state, and local government agencies, as well as utility and
transportation companies to locate on existing sites. Our objective is to pre-
sell capacity on our towers by promoting sites prior to construction. Rental
space on existing towers is also aggressively marketed and sold.

We utilize numerous public and proprietary databases to develop detailed
target marketing programs directed at auction block license awardees, existing
tenants and specific market groups. Mailings focus on regional build outs, new
sites and services. The use of databases, such as those with information on
sites, demographic data, licenses and deployment status, coupled with measured
coverage data and RF coverage prediction software, allows our sales and
marketing personnel to target specific carriers' needs for specific sites. To
foster productive relationships with our major existing tenants and potential
tenants, we have formed a team of account relationship managers. These managers
work to develop build-to-suit, site leasing services and site management
opportunities, as well as ensure that customers' emerging needs are translated
into new site products and services.

The marketing department maintains our visibility within the wireless
communications industry through regular advertising and public relations
efforts including actively participating in trade shows and generating regular
press releases, newsletters and targeted mailings (including promotional
flyers). Our promotional activities range from advertisements and site listings
in industry publications to maintaining a presence at national trade shows.
Potential clients are referred to our Web site, which contains Company
information as well as site listings. In addition, our sites are listed on the
Cell Site Express Web site. This Web site enables potential tenants to locate
existing structures by latitude, longitude or address. Clients can easily
contact us via e-mail through the Web site or Cell Site Express. Our network
services capabilities are marketed in conjunction with our tower footprints.

To follow up on targeted mailings and to cold-call on potential clients, we
have established a telemarketing department. Telemarketers field inbound and
outbound calls and forward leads to local

82
<PAGE>

sales representatives or relationship managers for closure. Local sales
representatives are stationed in each cluster to develop and foster close
business relationships with decision-makers in each customer organization.
Sales professionals work with marketing specialists to develop sales
presentations targeting specific client demands.

In addition to a dedicated, full-time sales and marketing staff, a number
of senior managers spend a significant portion of their efforts on sales and
marketing activities. These managers call on existing and prospective customers
and also seek greater visibility in the industry through speaking engagements
and articles in national publications. Furthermore, many of these managers have
been recognized as industry experts, are regularly quoted in articles and are
called on to testify at local hearings and to draft local zoning ordinances.

Public and community relations efforts include coordinating community
events, such as working with amateur radio clubs to supply emergency and
disaster recovery communications, charitable event sponsorship, and promoting
charitable donations through press releases.

Competition

In the United States, we compete with other independent tower owners, some
of which also provide site rental and network services; wireless carriers,
which own and operate their own tower networks; service companies that provide
engineering and site acquisition services; and other potential competitors,
such as utilities, outdoor advertisers and broadcasters, some of which have
already entered the tower industry. Wireless carriers that own and operate
their own tower networks generally are substantially larger and have greater
financial resources than us. We believe that tower location, capacity, price,
quality of service and density within a geographic market historically have
been and will continue to be the most significant competitive factors affecting
tower rental companies. We also compete for acquisition and new tower
construction opportunities with wireless carriers, site developers and other
independent tower operating companies and believe that competition for tower
site acquisitions will increase and that additional competitors will enter the
tower market, some of which may have greater financial resources than us.

The following is a list of the independent tower companies that we compete
with in the United States: American Tower Corporation, Pinnacle Towers,
SpectraSite, SBA Communications, WesTower, Unisite, LCC International and
Lodestar Communications.

The following companies are primarily competitors for our rooftop site
management activities in the United States: AAT, APEX, Commsite International,
JJS Leasing, Inc., Motorola, Signal One, Subcarrier Communications, Tower
Resources Management and Unisite.

We believe that the majority of our competitors in the site acquisition
business operate within local market areas exclusively, while a small minority
of firms appear to offer their services nationally, including SBA
Communications Corporation, Whalen & Company and Gearon & Company (a subsidiary
of American Tower Corporation). We offer our services nationwide and we believe
we are currently one of the largest providers of site development services to
the U.S. and international markets. The market includes participants from a
variety of market segments offering individual, or combinations of, competing
services. The field of competitors includes site acquisition consultants,
zoning consultants, real estate firms, right-of-way consulting firms,
construction companies, tower owners/managers, radio frequency engineering
consultants, telecommunications equipment vendors (which provide turnkey site
development services through multiple subcontractors) and carriers' internal
staff. We believe that carriers base their decisions on site development
services on certain criteria, including a company's experience, track record,
local reputation, price and time for completion of a project. We believe that
we compete favorably in these areas.

U.K. Operations

Overview

We own and operate, through our 80% interest in CTI, one of the world's
most established television and radio transmission networks and are expanding
our leasing of antenna space on our towers to a variety of wireless carriers.
We provide transmission services for four of the six digital terrestrial
television services in the U.K., two BBC analogue television services, six
national BBC radio services (including the first digital audio broadcast
service in the United Kingdom), 37 local BBC radio stations and two national
commercial radio services through our network of transmitters, which reach
99.4% of the U.K. population. These transmitters are located on approximately
1,300 towers, more than half of which we own and the balance of which are
licensed to us under a site-sharing agreement (the "Site-Sharing Agreement")
with NTL, our principal competitor in the United Kingdom. We have also secured
long-term contracts to provide digital television transmission services to the
BBC and ONdigital. See "--Significant Contracts". In addition to providing
transmission services, we also lease antenna space on our transmission
infrastructure to various communications service providers and provide
telecommunications network installation and maintenance services and
engineering consulting services.

Our core revenue generating activity in the United Kingdom is the analog
terrestrial transmission of radio and television programs broadcast by the BBC.
CTI's business, which was formerly owned by the BBC, was privatized under the
Broadcasting Act 1996 and sold to CTI in February 1997. At the time the BBC
Home Service Transmission Business was acquired, CTI entered into a 10-year
transmission contract with the BBC for the provision of terrestrial analog
television and analog and digital radio transmission services in the United
Kingdom. In the twelve months ended December 31, 1998, approximately 60.6% of
CTI's consolidated revenues were derived from the provision of services to the
BBC.

At December 31, 1998, we owned, leased or licensed 861 transmission sites
on which we operated 865 towers, including the 102 towers we acquired in the
Millennium acquisition. In addition, as of December 31, 1998 we were
constructing eight new towers on existing sites and had 112 site acquisition
projects in process for new tower sites. We have 54 revenue producing rooftop
sites that are occupied by our transmitters but are not available for leasing
to our customers. Our sites are located throughout England, Wales, Scotland and
Northern Ireland.

We expect to significantly expand our existing tower footprints in the
United Kingdom by building and acquiring additional towers. We believe our
existing tower network encompasses many of the most desirable tower locations
in the United Kingdom for wireless communications. However, due to the shorter
range over which communications signals carry (especially newer technologies
such as PCN) as compared to broadcast signals, wireless communications
providers require a denser footprint of towers to cover a given area.
Therefore, in order to increase the attractiveness of our tower footprints to
wireless communications providers, we will seek to build or acquire new
communications towers. Using our team of over 300 engineers with state-of-the-
art network design and radio frequency engineering expertise, we locate sites
and design towers that will be attractive to multiple tenants. We seek to
leverage such expertise by entering into build-to-suit contracts with various
carriers, such as BT, Cable & Wireless Communications, Cellnet, Dolphin,
Energis, Highway One, One2One, Orange and Scottish Telecom, thereby securing an
anchor tenant for a site before incurring capital expenditures for the site
build-out. As of December 31, 1998, we were building eight towers that we will
own. In addition, we expect to make strategic acquisitions of existing
communications sites (primarily those owned by wireless carriers) in order to
expand our infrastructure and to further leverage our site management
experience.

On March 5, 1999, we entered into an agreement with One2One pursuant to
which CTI has agreed to manage, develop and, at its option, acquire 821 towers.
These towers represent

84
<PAGE>

substantially all the towers in One2One's nationwide 900 MHz wireless network
in the United Kingdom. These towers will allow CTI to market a nationwide
network of towers to third generation wireless carriers in the United Kingdom
following the completion of the pending auction of such licenses by the U.K.
government.

We believe that we generally have significant capacity on our towers in the
United Kingdom. Although approximately 133 of our towers are poles with limited
capacity, we typically will be able to build new towers that will support
multiple tenants on these sites (subject to the applicable planning process).
We intend to upgrade these limited capacity sites where we believe we can
achieve appropriate returns to merit the necessary capital expenditure. For
example, in connection with a contract with Vodafone, we are upgrading 68 of
these sites with limited capacity. See "--Significant Contracts--Vodafone".
Approximately 59 of our sites are used for Medium Frequency ("MF") broadcast
transmissions. At this frequency, the entire tower is used as the transmitting
antenna and is therefore electrically "live". Such towers are therefore
unsuitable for supporting other tenant's communications equipment. However, MF
sites generally have substantial ground area available for the construction of
new multiple tenant towers.

Transmission Business

Analog. For the twelve months ended December 31, 1998, CTI generated
approximately 52.8% of its revenues from the provision of analog broadcast
transmission services to the BBC. Pursuant to the BBC Analog Transmission
Contract, we provide terrestrial transmission services for the BBC's analog
television and radio programs and certain other related services (including BBC
digital radio) for an initial 10-year term through March 31, 2007. See "--
Significant Contracts". For the twelve months ended December 31, 1998, the BBC
Analog Transmission Contract generated revenues of approximately (Pounds)49.4
million ($82.1 million) for us.

In addition to the BBC Analog Transmission Contract, we have separate
contracts to provide maintenance and transmission services for two national
radio stations, Virgin Radio and Talk Radio. These contracts are for periods of
eight years commencing from, respectively, March 31, 1993 and February 4, 1995.

We own all of the transmission equipment used for broadcasting the BBC's
domestic radio and television programs, whether located on one of CTI's sites
or on an NTL or other third-party site. As of December 31, 1998, CTI had 3,465
transmitters, of which 2,196 were for television broadcasting and 1,269 were
for radio.

A few of our most powerful television transmitters together cover the
majority of the U.K. population. The coverage achieved by the less powerful
transmitters is relatively low, but is important to the BBC's ambition of
attaining universal coverage in the United Kingdom. This is illustrated by the
following analysis of the population coverage of our analog television
transmitters:

<TABLE>
<CAPTION>
Combined
Number of sites population

-------------------- ----------
<S> <C>

top 16...................................... 79
top 26...................................... 86
top 51...................................... 92
all......................................... 99.4
</TABLE>

All of our U.K. transmitters are capable of unmanned operation and are
maintained by mobile maintenance teams from 27 bases located across the United
Kingdom. Access to the sites is strictly controlled for operational and
security reasons, and buildings at 140 of the sites are protected by

85
<PAGE>

security alarms connected to CTI's Technical Operations Centre at Warwick. The
Site-Sharing Agreement provides us with reciprocal access rights to NTL's
broadcast transmission sites on which we have equipment.

Certain of our transmitters that serve large populations or important
geographic areas have been designated as priority transmitters. These
transmitters have duplicated equipment so that a single failure will not result
in total loss of service but will merely result in an output-power reduction
that does not significantly degrade the service to most viewers and listeners.

Digital. We have entered into contracts with the holders (including the
BBC) of four of the six DTT multiplexes allocated by the U.K. government to
design, build and operate their digital transmission networks. In connection
with the implementation of DTT, new transmission infrastructure will be
required. We have committed to invest approximately (Pounds)100.0 million
($170.0 million) for the build out of new infrastructure to support DTT over
the next two years, (Pounds)55.3 million ($92.0 million) of which we had
already invested by December 31, 1998. By the year 2000, 81 transmission sites
will need to be upgraded with new transmitters and associated systems to
support DTT. Of these sites, 49 are owned by us with the remainder owned by
NTL. An arrangement similar to that of the Site-Sharing Agreement is being
negotiated to govern the particular issues arising out of the sharing of
digital transmission sites between NTL and us.

We successfully began commercial operation of the DTT networks from an
initial 22 transmission sites on November 15, 1998. This launch marks the first
stage of the project to introduce the digital broadcast system that will
eventually replace conventional analog television services in the United
Kingdom. As the network size expands during 1999, the number of viewers who are
able to receive the service will increase significantly. We have accepted an
invitation from the U.K. television regulator, the Independent Television
Commission (ITC), to play a major role in planning further DTT network
extensions to be built in the year 2000 and beyond.

We are currently the sole provider of transmission services for digital
radio broadcasts in the United Kingdom. In September 1995, the BBC launched its
initial DAB scheme over our transmission network, and this service is now
broadcast to approximately 60% of the U.K. population. A license for an
independent national digital radio network was awarded to the Digital One
consortium during 1998 and it is expected that this service will commence
during 1999. We are in negotiations to provide accommodation and access to
masts and antennas at 24 transmission sites to support the launch of Digital
One. In addition, local digital radio licenses will be awarded during 1999. We
believe we are well positioned to become the transmission service provider to
the winners of such licenses.

Site Rental

The BBC transmission network provides a valuable initial footprint for the
creation of wireless communications networks. As of December 31, 1998,
approximately 200 companies rented antenna space on approximately 405 of CTI's
919 towers and rooftops. These site rental agreements have normally been for
three to 12 years and are generally subject to rent reviews every three years.
Site sharing customers are generally charged annually in advance, according to
rate cards that are based on the antenna size and position on the tower. Our
largest site rental customer in the United Kingdom is NTL under the Site-
Sharing Agreement. This agreement generated approximately (Pounds)592,000
($984,400) of site rental revenue in December 1998.

We also provide a range of site maintenance services in order to support
and enhance our U.K. site rental business. We believe that by offering services
such as antenna, base station and tower maintenance and monitoring, we are able
to offer quality services to retain our existing customers and attract future
customers to our communications sites. We complement our U.K. transmission
experience with our site management experience in the United States to provide
customers with a top-of-the-line package of service and technical support.

=== =============== ========
</TABLE>

Other than NTL, CTI's largest (by revenue) site rental customers consist
mainly of wireless carriers such as Cellnet, One2One, Orange and Vodafone.
Revenues from these non-BBC sources are expected to become an increasing
portion of CTI's total U.K. revenue base, as the acquired BBC Home Service
Transmission Business is no longer constrained by governmental restrictions on
the BBC's commercial activities. We believe that the demand for site rental
from communication service providers will increase in line with the expected
growth of these communication services in the United Kingdom.

We have master lease agreements with all of the major U.K.
telecommunications site users including BT, Cable & Wireless Communications,
Cellnet, Dolphin, Energis, Highway One, One2One, Orange, Scottish Telecom and
Vodafone. These agreements typically specify the terms and conditions
(including pricing and volume discount plans) under which these customers have
access to all sites within our U.K. portfolio. Customers make orders for
specific sites using the standard terms included in the master lease
agreements. As of December 31, 1998, there were approximately 400 applications
in process for installations at existing sites under such agreements.

Network Services

CTI provides broadcast and telecommunications engineering services to
various customers in the United Kingdom. We retained all the BBC Home Service
Transmission Business employees upon CTI's acquisition. Accordingly, we have
engineering and technical staff of the caliber and experience necessary not
only to meet the requirements of our current customer base, but also to meet
the challenges of developing digital technology. Within the United Kingdom, CTI
has worked with several telecommunications operations on design and build
projects as they roll-out their networks. CTI has had success in bidding for
broadcast consulting contracts, including, over the last four years, in
Thailand, Taiwan, Poland and Sri Lanka.

With the expertise of our engineers and technical staff, we are a turn-key
provider to the wireless communications and broadcast industries. We can
provide customers with a ready-to-operate network infrastructure or any of the
component services involved therein. Such services include network design and
site selection, site acquisition, site development and antenna installation.

87
<PAGE>

contract basis. Our network design and site selection services provide our
customers with relevant information including recommendations regarding
location and height of towers, appropriate types of antennas, transmission
power and frequency selection and related fixed network considerations.

Site Acquisition. In the United Kingdom, we are involved in site
acquisition services for our own purposes and for third parties. We recognize
that the site acquisition phase often carries the highest risk for a project.
To ensure the greatest possible likelihood of success and timely acquisition,
we combine a desktop survey of potential barriers to development with a
physical site search that includes initial design analyses, CDM assessments
and, where necessary, line-of-sight surveys. We leverage off our experience in
site acquisition and co-location when meeting with local planning authorities.

Site Development and Antenna Installation. We use a combination of external
and internal resources for site construction. Our engineers are experienced in
both construction techniques and construction management, ensuring an efficient
and simple construction phase. Selected civil contractors are managed by CTI
staff for the ground works phase. Specialist erection companies, with whom we
have a long association, are used for tower installation. Final antenna
installation is undertaken by our own experienced teams.

Site Management and Other Services. We also provide complete site
management, preventive maintenance, fault repair and system management services
to the Scottish Ambulance Service. We also maintain a mobile radio system for
the Greater Manchester Police and provide maintenance and repair services for
transmission equipment and site infrastructure.

Significant Contracts

CTI's principal analog broadcast transmission contract is the BBC Analog
Transmission Contract. CTI also has entered into two digital television
transmission contracts, the BBC Digital Transmission Contract and the ONdigital
Digital Transmission Contract (as defined). CTI also provides facilities to NTL
(in its capacity as a broadcast transmission provider to non-CTI customers)
under the Site-Sharing Agreement. CTI also has long-term service agreements
with broadcast customers such as Virgin Radio and Talk Radio. In addition, CTI
has several agreements with telecommunications providers, including leases,
site management contracts and independent contractor agreements. CTI has
entered into contracts to design and build infrastructure for customers such as
Cellnet, One2One, Orange, Scottish Telecom and Vodafone.

BBC Analog Transmission Contract

CTI entered into a 10-year transmission contract with the BBC for the
provision of terrestrial analog television and analog and digital radio
transmission services in the United Kingdom at the time the BBC Home Service
Transmission Business was acquired, which contract was subsequently amended on
July 16, 1998 (the "BBC Analog Transmission Contract") to incorporate a small
number of minor modifications requested by the BBC. The BBC Analog Transmission
Contract provides for charges of approximately (Pounds)46.5 million ($77.3
million) to be payable by the BBC to CTI for the year ended March 31, 1998 and
each year thereafter to the termination date, adjusted annually at the
inflation rate less 1%. In addition, for the duration of the contract an annual
payment of (Pounds)300,000 ($498,840) is payable by the BBC for additional
broadcast-related services. At the BBC's request, since October 1997, the
number of television broadcast hours has been increased to 24 hours per day for
the BBC's two national television services, which has added over
(Pounds)500,000 ($831,400) annually to the payments made by the BBC to the
Company.

88
<PAGE>

The BBC Analog Transmission Contract also provides for CTI to be liable to
the BBC for "service credits" (i.e., rebates of its charges) in the event that
certain standards of service are not attained as a result of what the contract
characterizes as "Accountable Faults" or the failure to meet certain "response
times" in relation to making repairs at certain key sites. We believe that CTI
is well-equipped to meet the BBC's service requirements by reason of the
collective experience its existing management gained while working with the
BBC. Following completion of three formal six-month performance reviews, CTI
achieved a 100% "clean sheet" performance, incurring no service credit
penalties.

The initial term of the BBC Analog Transmission Contract ends on March 31,
2007. Thereafter, the BBC Analog Transmission Contract may be terminated with
12 months' prior notice by either of the parties, expiring on March 31 in any
contract year, from and including March 31, 2007. It may also be terminated
earlier (i) by mutual agreement between CTI and the BBC, (ii) by one party upon
the bankruptcy or insolvency of the other party within the meaning of section
123 of the Insolvency Act 1986, (iii) upon certain force majeure events with
respect to the contract as a whole or with respect to any site (in which case
the termination will relate to that site only), (iv) by the non-defaulting
party upon a material breach by the other party and (v) upon the occurrence of
certain change of control events (as defined in the BBC Analog Transmission
Contract).

BBC Commitment Agreement

On February 28, 1997, in connection with the acquisition of the BBC Home
Service Transmission Business, the Company, TdF, TeleDiffusion de France S.A.,
which is the parent company of TdF and DFI ("TdF Parent"), and the BBC entered
into the BBC Commitment Agreement (the "BBC Commitment Agreement"), whereby we
and TdF agreed (i) not to dispose of any shares in CTSH or any interest in such
shares (or enter into any agreement to do so) until February 28, 2000; and (ii)
to maintain various minimum indirect ownership interests in CTI and CTSH for
periods ranging from three to five years commencing February 28, 1997. These
provisions restrict our ability and the ability of TdF to sell, transfer or
otherwise dispose of their respective CTSH shares (and, indirectly, their CTI
shares). The restrictions do not apply to disposals of which the BBC has been
notified in advance and to which the BBC has given its prior written consent,
which, subject to certain exceptions, consent shall not be unreasonably
withheld or delayed. The BBC has consented to waive the above restrictions (i)
to enable the Company and TdF to enter into the Governance Agreement and the
CTSH Shareholders' Agreement and (ii) to allow the exercise of rights under
such agreements and (iii) to permit the roll-up of CTI immediately prior to the
IPO.

The BBC Commitment Agreement also required TdF Parent and us to enter into
a services agreements with CTI. The original services agreement entered into by
TdF Parent and CTI on February 28, 1997 (pursuant to which TdF makes available
certain technical consultants, executives and engineers to CTI) was amended on
August 21, 1998 to extend the original minimum term of services provided from
three years to seven years, commencing February 28, 1997, thereafter terminable
on 12-month's prior notice given by CTI to TdF after February 28, 2003. See
"The Roll-Up--Roll-Up Arrangements--CTI Series Agreement".

ONdigital Digital Transmission Contract

In 1997, the Independent Television Commission awarded ONdigital three of
the five available commercial digital terrestrial television multiplexes for
new program services. We bid for and won the 12 year contract from ONdigital to
build and operate its digital television transmission network (the "ONdigital
Digital Transmission Contract"). The contract provides for approximately
(Pounds)20.0 million ($34.0 million) of revenue per year from 2001 to 2008,
with lesser amounts payable before and after these years and with service
credits repayable for performance below agreed thresholds.

89
<PAGE>

BBC Digital Transmission Contract

In 1998, we bid for and won the 12 year contract from the BBC to build and
operate its digital terrestrial television transmission network (the "BBC
Digital Transmission Contract"). This contract provides for approximately
(Pounds)10.5 million ($17.8 million) of revenue per year (assuming the BBC
commits to the full DTT roll-out contemplated by the BBC Digital Transmission
Contract) during the 12 year period, with service credits repayable for
performance below agreed thresholds. There is a termination provision during
the three-month period following the fifth anniversary of our commencement of
digital terrestrial transmission services for the BBC exercisable by the BBC
but only if the BBC's Board of Governors determines, in its sole discretion,
that DTT in the United Kingdom does not have sufficient viewership to justify
continued DTT broadcasts. Under this provision, the BBC will pay us a
termination fee in cash that substantially recovers the Company's capital
investment in the network, and any residual ongoing operating costs and
liabilities. Like the BBC Analog Transmission Contract, the contract is
terminable upon the occurrence of certain change of control events (as defined
in the BBC Digital Transmission Contract).

BT Digital Distribution Contract

Under the BBC Digital Transmission Contract and the ONdigital Digital
Transmission Contract, in addition to providing digital terrestrial
transmission services, CTI has agreed to provide for the distribution of the
BBC's and ONdigital's broadcast signals from their respective television
studios to CTI's transmission network. Consequently, in May 1998, CTI entered
into a 12 year distribution contract (the "BT Digital Distribution Contract")
with British Telecommunications plc ("BT") (with provisions for extending the
term), in which BT has agreed to provide fully duplicated, fiber-based, digital
distribution services, with penalties for late delivery and service credits for
failure to deliver 99.99% availability.

Site-Sharing Agreement

In order to optimize service coverage and enable viewers to receive all
analog UHF television services using one receiving antenna, the BBC, as the
predecessor to CTI, and NTL made arrangements to share all UHF television
sites. This arrangement was introduced in the 1960s when UHF television
broadcasting began in the United Kingdom. In addition to service coverage
advantages, the arrangement also minimizes costs and avoids the difficulties of
obtaining additional sites.

Under the Site-Sharing Agreement, the party that is the owner, lessee or
licensee of each site is defined as the "Station Owner". The other party (the
"Sharer") is entitled to request a license to use certain facilities at that
site. The Site-Sharing Agreement and each site license provide for the Station
Owner to be paid a commercial license fee in accordance with the Site-Sharing
Agreement ratecard and for the Sharer to be responsible, in normal
circumstances, for the costs of accommodation and equipment used exclusively by
it. The Site-Sharing Agreement may be terminated with five years' prior notice
by either of the parties and expires on December 31, 2005 or on any tenth
anniversary of that date. It may also be terminated (i) following a material
breach by either party which, if remediable, is not remedied within 30 days of
notice of such breach by the non-breaching party, (ii) on the bankruptcy or
insolvency of either party and (iii) if either party ceases to carry on a
broadcast transmission business or function.

Negotiations are in progress between NTL and us to amend the Site-Sharing
Agreement to account for the build-out of digital transmission sites and
equipment, a new rate card related to site sharing fees for new digital
facilities and revised operating and maintenance procedures related to digital
equipment.

90
<PAGE>

Vodafone

On April 16, 1998, under Vodafone's master lease agreement with us,
Vodafone agreed to locate antennas on 122 of our existing communication sites
in the United Kingdom. The first 39 sites had been completed by the end of
December 1998. This included 4 sites at which a new tower had been constructed
to replace an existing structure of limited capacity. The remaining sites are
expected to be completed by end of July 1999 and will include the construction
of a further 60 replacement towers. After their upgrade, these sites will be
able to accommodate additional tenants.

Customers

For the twelve months ended December 31, 1998, the BBC accounted for
approximately 60.6% of CTI's consolidated revenues. This percentage has
decreased from 64.6% for the twelve months ended March 31, 1998 and is expected
to continue to decline as CTI continues to expand its site rental business. CTI
provides all four U.K. PCN/cellular operators (Cellnet, One2One, Orange and
Vodafone) with infrastructure services and also provides fixed
telecommunications operators, such as BT, Cable & Wireless Communications,
Energis and Scottish Telecom, with microwave links and backhaul infrastructure.
The following is a list of some of CTI's leading site rental customers by
industry segment.

Sales and Marketing

We have 20 sales and marketing personnel in the United Kingdom who identify
new revenue-generating opportunities, develop and maintain key account
relationships, and tailor service offering to meet the needs of specific
customers. An excellent relationship has been maintained with the BBC, and
successful new relationships have been developed with many of the major
broadcast and wireless communications carriers in the United Kingdom. We have
begun to actively cross-sell our products and services so that, for example,
site rental customers are also offered build-to-suit services.

Competition

NTL, the privatized engineering division of the IBA and now a subsidiary of
NTL Inc. (formerly International CableTel Inc.), is CTI's primary competition
in the terrestrial broadcast transmission market in the United Kingdom. NTL
provides analog transmission services to ITV, Channels 4 and 5, and S4C. It
also has been awarded the transmission contract for the new DTT multiplex
service from Digital 3 & 4 Limited, and a similar contract for the DTT service
for SDN (CTI has been awarded similar contracts for the BBC and ONdigital--
serving a total of four multiplexes compared with NTL's two). Since its
creation in 1991, NTL has diversified from its core television broadcasting
business using its transmission infrastructure to enter into the radio
transmission and telecommunications sectors.

91
<PAGE>

Although CTI and NTL are direct competitors, they have reciprocal rights to
the use of each others' sites for broadcast transmission usage in order to
enable each of them to achieve the necessary country-wide coverage. This
relationship is formalized by the Site-Sharing Agreement entered into in 1991,
the time at which NTL was privatized.

NTL also offers site rental on approximately 1,000 of its sites (some of
which are managed on behalf of third parties). Like CTI, NTL offers a full
range of site-related services to its customers, including installation and
maintenance. CTI believes its towers to be at least as well situated as NTL's
and that it will be able to expand its own third-party site-sharing
penetration. CTI also believes that its penetration of this market has to date
lagged behind NTL only because of the governmental restrictions on the
commercial activities of CTI's business prior to its privatization.

All four U.K. mobile operators own site infrastructure and lease space to
other users. Their openness to sharing with direct competitors varies by
operator. Cellnet and Vodafone have agreed to cut site costs by jointly
developing and acquiring sites in the Scottish Highlands. BT and Cable &
Wireless Communications are both major site sharing customers but also compete
by leasing their own sites to third parties. BT's position in the market is
even larger when considered in combination with its interest in Cellnet.

Several other companies compete in the market for site rental. These
include British Gas, Racal Network Systems, Aerial Sites Plc, Relcom Aerial
Services and the Royal Automobile Club. Some companies own sites initially
developed for their own networks, while others are developing sites
specifically to exploit this market.

CTI faces competition from a large number of companies in the provision of
network services. The companies include NTL, specialty consultants and
equipment manufacturers such as Nortel and Ericsson.

Properties

In the United States, the Company's interests in its tower sites are
comprised of a variety of fee interests, leasehold interests created by long-
term lease agreements, private easements and easements, licenses or rights-of-
way granted by government entities. In rural areas, a tower site typically
consists of a three- to five-acre tract, which supports towers, equipment
shelters and guy wires to stabilize the structure. Less then 3,000 square feet
are required for a self-supporting tower structure of the kind typically used
in metropolitan areas. The Company's land leases generally have five- or ten-
year terms and frequently contain one or more renewal options. Some land leases
provide "trade-out" arrangements whereby the Company allows the landlord to use
tower space in lieu of paying all or part of the land rent. As of December 31,
1998, the Company had approximately 384 land leases. Pursuant to the Senior
Credit Facility, the Company's senior lenders have liens on a substantial
number of the Company's land leases and other property interests in the United
States.

In the United Kingdom, tower sites range from less than 400 square feet for
a small rural TV booster station to over 50 acres for a high-power radio
station. As in the United States, the site accommodates the towers, equipment
buildings or cabins and, where necessary, guy wires to support the structure.
Land is either owned freehold, which is usual for the larger sites, or is held
on long-term leases that generally have terms of 21 years or more.

Legal Proceedings

We are occasionally involved in legal proceedings that arise in the
ordinary course of business. Most of these proceedings are appeals by
landowners of zoning and variance approvals of local zoning boards. While the
outcome of these proceedings cannot be predicted with certainty,

92
<PAGE>

management does not expect any pending matters to have a material adverse
effect on our financial condition or results of operations. We are currently in
discussions with the Department of Labor (the "DOL") to settle an investigation
the DOL has conducted into employment practices put into place prior to our
acquisition of CCI. Upon notification by the DOL of its investigation, the
practices were ceased. We anticipate the settlement to be approximately
$200,000.

Employees

At March 1, 1999, we employed 928 people worldwide. Other than in the
United Kingdom, we are not a party to any collective bargaining agreements. In
the United Kingdom, we are party to a collective bargaining agreement with the
Broadcast, Entertainment, Cinematographic and Technicians Union. This agreement
establishes bargaining procedures relating to the terms and conditions of
employment for all of CTI's non-management staff. We have not experienced any
strikes or work stoppages, and management believes that our employee relations
are satisfactory.

Regulatory Matters

United States

Federal Regulations. Both the FCC and FAA regulate towers used for wireless
communications transmitters and receivers. Such regulations control the siting
and marking of towers and may, depending on the characteristics of particular
towers, require registration of tower facilities. Wireless communications
devices operating on towers are separately regulated and independently licensed
based upon the particular frequency used.

The FCC, in conjunction with the FAA, has developed standards to consider
proposals for new or modified antenna structures. These standards mandate that
the FCC and the FAA consider the height of proposed antenna structures, the
relationship of the structure to existing natural or man-made obstructions and
the proximity of the antenna structures to runways and airports. Proposals to
construct or to modify existing antenna structures above certain heights are
reviewed by the FAA to ensure the structure will not present a hazard to
aviation. The FAA may condition its issuance of a no-hazard determination upon
compliance with specified lighting and/or marking requirements. The FCC will
not license the operation of wireless telecommunications devices on towers
unless the tower is in compliance with the FAA's rules and is registered with
the FCC, if necessary. The FCC will not register a tower unless it has been
cleared by the FAA. The FCC may also enforce special lighting and painting
requirements. Owners of wireless transmissions towers may have an obligation to
maintain painting and lighting to conform to FAA and FCC standards. Tower
owners may also bear the responsibility of notifying the FAA of any tower
lighting outage. The Company generally indemnifies its customers against any
failure to comply with applicable regulatory standards. Failure to comply with
the applicable requirements may lead to civil penalties.

The 1996 Telecom Act limits certain state and local zoning authorities'
jurisdiction over the construction, modification and placement of towers. The
new law prohibits any action that would (i) discriminate between different
providers of personal wireless services or (ii) prohibit or have the effect of
prohibiting the provision of personal wireless service. Finally, the 1996
Telecom Act requires the federal government to help licensees for wireless
communications services gain access to preferred sites for their facilities.
This may require that federal agencies and departments work directly with
licensees to make federal property available for tower facilities.

Local Regulations. Local regulations include city and other local
ordinances, zoning restrictions and restrictive covenants imposed by community
developers. These regulations vary greatly, but typically require tower owners
to obtain approval from local officials or community standards organizations
prior to tower construction. Local zoning authorities generally have been
hostile to construction of new transmission towers in their communities because
of the height and visibility of the towers.

Licenses Under the Communications Act of 1934. We hold, through certain of
our subsidiaries, licenses for radio transmission facilities granted by the
FCC, including licenses for common carrier microwave and commercial mobile
radio services ("CMRS"), including SMR and paging facilities, as well as
private mobile radio services ("PMRS") including industrial/business radio
facilities, which are subject to additional regulation by the FCC. We are
required to obtain the FCC's approval prior to the transfer of control of any
of our FCC licenses. Consummation of the IPO and the Roll-Up would have
resulted in a transfer of control of us under the FCC's rules and policies if,
after such transactions, over 50% of our voting stock would have been owned by
new stockholders.

We, as the parent company of the licensees of common carrier and CMRS
facilities, are also subject to Section 310(b)(4) of the Communications Act of
1934, as amended, which would limit us to a maximum of 25% foreign ownership
absent a ruling from the FCC that foreign ownership in excess of 25% is in the
public interest. In light of the World Trade Organization Agreement on Basic
Telecommunications Services ("WTO Agreement"), which took effect on February 5,
1998, the FCC has determined that such investments are generally in the public
interest if made by individuals and entities from WTO-member nations. We are
over 25% foreign owned by companies headquartered in France, the United Kingdom
and New Zealand. See "Principal and Selling Stockholders". Each of these
nations is a signatory to the WTO Agreement. The FCC has granted approval of up
to 49.9% foreign ownership of us, at least 25% of which will be from WTO-member
nations.

United Kingdom

Telecommunications systems and equipment used for the transmission of
signals over radio frequencies have to be licensed in the United Kingdom. These
licenses are issued on behalf of the British Government by the Secretary of
State for Trade and Industry under the Telecommunications Act 1984 and the
Wireless Telegraphy Acts 1949, 1968 and 1998. CTI has a number of such licenses
under which it runs the telecommunications distribution and transmission
systems which are necessary for the provision of its transmission services.
CTI's operations are subject to comprehensive regulation under the laws of the
United Kingdom.

Licenses under the Telecommunications Act 1984

CTI has the following three licenses under the Telecommunications Act 1984:

Transmission License. The Transmission License is a renewable license to
run telecommunications systems for the transmission via wireless telegraphy of
broadcasting services. This license is for a period of at least twenty-five
years from January 23, 1997, and is CTI's principal license. Its main
provisions include:

(i) a price control condition covering the provision of all analog radio
and television transmission services to the BBC under the BBC Analog
Transmission Agreement (for an initial price of approximately (Pounds)44
million for regulated elements of the services provided by CTI under the
BBC Analog Transmission Agreement in the year ended March 31, 1997,
subject to an increase cap which is 1% below the rate of increase in the
Retail Price Index over the previous calendar year). The current price
control condition applies until March 31, 2006;

(ii) a change of control provision which requires notification of
acquisitions of interest in CTI of more than 20% by a public
telecommunications operator or any Channel 3 or Channel 5 licensee, which
acquisitions entitle the Secretary of State to revoke the license;

(iii) a site sharing requirement requiring CTI to provide space on its
towers to analog and digital broadcast transmission operators and
including a power for the Director General of

94
<PAGE>

Telecommunications ("OFTEL"), as the regulator, to determine prices if
there is failure between the site owner and the prospective site sharer to
agree to a price;

(iv) a fair trading provision enabling OFTEL to act against anti-
competitive behavior by the licensee; and

(v) a prohibition on undue preference or discrimination in the provision
of the services it is required to provide third parties under the
Transmission License.

OFTEL has made a determination with respect to a complaint made by Classic
FM and NTL in respect of certain charges, imposed previously by the BBC under
the Site-Sharing Agreement with NTL for the use by Classic FM of BBC radio
antennas and passed on to Classic FM by NTL. OFTEL's position is that the Site-
Sharing Agreement did not cover charges for new services to customers such as
Classic FM, thereby enabling OFTEL to intervene and determine the appropriate
rate under the "Applicable Rate" mechanism in CTI's Transmission License. This
procedure could result in the fees NTL pays to CTI for site sharing facilities
for Classic FM, currently calculated under the Site-Sharing Agreement, being
determined at a reduced rate and otherwise not being covered by the terms of
any existing contract which could lead to a diminution of CTI's income of
approximately (Pounds)300,000 per annum (equivalent to approximately 0.4% of
revenues and 1.0% of EBITDA for the fiscal year ended March 31, 1997). CTI has
applied for leave to obtain a judicial review of this decision. In addition,
CTI has made a provision of approximately (Pounds)1.9 million relating to any
rate adjustment imposed by OFTEL with respect to previous charges for Classic
FM under the Site-Sharing Agreement.

CTI is discussing with OFTEL certain amendments to CTI's Telecommunications
Act Transmission License to ensure that the price control condition
accommodates the provision by CTI of additional contractually agreed upon
services to the BBC in return for additional agreed upon payments. See "Risk
Factors--Regulatory Compliance and Approval".

The Secretary of State has designated the Transmission License a public
telecommunications operator ("PTO") license in order to reserve to himself
certain emergency powers for the protection of national security. The PTO
designation is, however, limited to this objective. CTI does not have a full
domestic PTO license and does not require one for its current activities. The
Department of Trade and Industry has, nevertheless, indicated that it would be
willing to issue CTI such a license. As a result CTI would gain wider powers to
provide services to third parties including public switched voice telephony and
satellite uplink and would grant CTI powers to build out its network over
public property (so-called "code powers").

General Telecom License. The General Telecom License is a general license
to run telecommunications systems and authorizes CTI to run all the necessary
telecommunications systems to convey messages to its transmitter sites (e.g.,
via leased circuits or using its own microwave links). The license does not
cover the provision of public switched telephony networks (which would require
a PTO license as described above).

Satellite License. The Satellite License is a license to run
telecommunications systems for the provision of satellite telecommunication
services and allows the conveyance via satellite of messages, including data
and radio broadcasting. The license excludes television broadcasting direct to
the home via satellite although distribution via satellite of television
broadcasting services which are to be transmitted terrestrially is permitted.

Licenses under the Wireless Telegraphy Acts 1949, 1968 and 1998

CTI has a number of licenses under the Wireless Telegraphy Acts 1949, 1968
and 1998, authorizing the use of radio equipment for the provision of certain
services over allocated radio frequencies including:

(i) a Broadcasting Services License in relation to the transmission
services provided to the BBC, Virgin Radio and Talk Radio;

95
<PAGE>

(ii) a Fixed Point-to-Point Radio Links License;

(iii) two DAB Test and Development Licenses; and

(iv) DTT Test & Development Licenses.

All the existing licenses under the Wireless Telegraphy Acts 1949, 1968 and
1998 have to be renewed annually with the payment of a significant fee. The
BBC, Virgin Radio and Talk Radio have each contracted to pay their portion of
these fees. ONdigital is obligated under the ONdigital Digital Transmission
Contract to pay most of their portion of these fees.

Environmental Matters

Our operations are subject to foreign, federal, state and local laws and
regulations relating to the management, use, storage, disposal, emission, and
remediation of, and exposure to, hazardous and nonhazardous substances,
materials and wastes ("Environmental Laws"). As an owner and operator of real
property, we are subject to certain Environmental Laws that impose strict,
joint and several liability for the cleanup of on-site or off-site
contamination relating to existing or historical operations, and also could be
subject to personal injury or property damage claims relating to such
contamination. We are potentially subject to cleanup liabilities in both the
United States and the United Kingdom.

We are also subject to regulations and guidelines that impose a variety of
operational requirements relating to RF emissions. The potential connection
between RF emissions and certain negative health effects, including some forms
of cancer, has been the subject of substantial study by the scientific
community in recent years. To date, the results of these studies have been
inconclusive. Although we have not been subject to any claims relating to RF
emissions, we have established operating procedures designed to reduce employee
exposures to RF emissions and are presently evaluating certain of our towers
and transmission equipment in the United States and the United Kingdom to
determine whether RF emission reductions are possible.

In addition, we are subject to licensing, registration and related
requirements concerning tower siting, construction and operation. In the United
States, the FCC's decision to license a proposed tower may be subject to
environmental review pursuant to the National Environmental Policy Act of 1969
("NEPA"), which requires federal agencies to evaluate the environmental impacts
of their decisions under certain circumstances. The FCC regulations
implementing NEPA place responsibility on each applicant to investigate any
potential environmental effects of a proposed operation and to disclose any
significant effects on the environment in an environmental assessment prior to
commencing construction. In the event the FCC determines that a proposed tower
would have a significant environmental impact, the FCC would be required to
prepare an environmental impact statement. This process could significantly
delay or prevent the registration or construction of a particular tower, or
make tower construction more costly. In certain jurisdictions, local laws or
regulations may impose similar requirements.

We believe that we are in substantial compliance with all applicable
Environmental Laws. Nevertheless, there can be no assurance that the costs of
compliance with existing or future Environmental Laws will not have a material
adverse effect on our business, results of operations, or financial condition.

THE PROPOSED TRANSACTIONS

Proposed BAM JV

On December 8, 1998, BAM, certain of the Transferring Partnerships, the
Company and CCA Investment Corp., our wholly owned indirect subsidiary
("CCAIC"), entered into the Formation Agreement to form the Proposed BAM JV to
own and operate a significant majority of BAM's towers. We will own
approximately 62.3% of the Proposed BAM JV and BAM and certain of its
affiliates will own the remaining 37.7% along with a 0.001% interest in the
joint venture's operating subsidiary. For financial reporting purposes, we
intend to consolidate the Proposed BAM JV's results of operations and financial
condition with our own.

We will manage the day-to-day operations of the Proposed BAM JV. The
Proposed BAM JV will actively seek to add additional tenants to its towers in
order to increase its revenues. The Proposed BAM JV will also construct and own
new towers that are needed by BAM's wireless communications business. See "--
Build-to-Suit Agreement" and "--Global Lease". The Proposed BAM JV will have
regional offices that will be staffed primarily with our employees to perform
marketing, billing, operations and maintenance functions.

Although the Proposed BAM JV is expected to be formed during the first
quarter of 1999, the Formation Agreement is subject to a number of significant
conditions. There can be no assurance that the Proposed BAM JV will be formed
on the terms described in this document or at all.

The following descriptions of the agreements related to the Proposed BAM JV
are summaries of the material portions of those agreements. These descriptions
are qualified in their entirety by reference to the complete texts of the
agreements, each of which is available as set forth under the heading
"Available Information".

Formation Agreement

Formation of the Proposed BAM JV. Pursuant to the Formation Agreement,
CCAIC will contribute $250.0 million in cash and approximately 15.6 million
shares of our common stock (valued at $197.0 million) to the Proposed BAM JV.
BAM and the Transferring Partnerships will transfer approximately 1,427 towers
along with related assets and liabilities to the Proposed BAM JV. The Proposed
BAM JV expects to borrow $180.0 million under a committed $250.0 million
revolving credit facility. The joint venture will make a $380.0 million cash
distribution to BAM.

Concurrently with the formation of the joint venture, BAM and the Proposed
BAM JV will enter into a master Build-to-Suit Agreement, a Global Lease and a
transitional services agreement and we will enter into a services agreement
with the Proposed BAM JV.

Terms and Conditions. In connection with its contribution of assets and
liabilities to the Proposed BAM JV, BAM is making certain representations and
warranties to the Proposed BAM JV concerning the contributed assets and
liabilities. In general, the Proposed BAM JV will have until June 30, 2000, to
raise any claims for indemnification for breaches of the representations and
warranties by BAM. However, BAM's indemnification obligations are subject to a
number of significant limitations including a per occurrence deductible of
$25,000, an aggregate deductible of $7.5 million and an absolute cap of $195.0
million.

The formation of the Proposed BAM JV is subject to a number of significant
conditions. These conditions include:

. accuracy of the representations and warranties of BAM and us;

. receipt of bank financing by the Proposed BAM JV;

97
<PAGE>

. receipt of certain third party consents required for the transfer of the
tower assets to the Proposed BAM JV;

. receipt of regulatory approvals;

. absence of litigation;

. receipt of certain environmental studies; and

. absence of any material adverse effect with respect to our business,
assets, operations, conditions (financial or otherwise) or prospects and
of our subsidiaries taken as a whole.

There can be no assurance that these conditions will be satisfied or waived. If
they are not satisfied or waived, the Proposed BAM JV may not be formed on the
terms described in this document or at all. See "Risk Factors--The Proposed BAM
JV May Not Occur".

Build-to-Suit Agreement

In connection with the formation of the Proposed BAM JV, BAM and the
Proposed BAM JV will enter into the Build-to-Suit Agreement. Pursuant to the
Build-to-Suit Agreement and subject to certain conditions, BAM and the Proposed
BAM JV have agreed that (i) the next 500 towers to be built for BAM's wireless
communications business will be constructed and owned by the Proposed BAM JV
and (ii) immediately thereafter the Proposed BAM JV will have a right of first
refusal to construct the next 200 additional towers to be built for BAM. BAM is
required to submit these 700 site proposals to the Proposed BAM JV during the
five-year period following the formation of the joint venture; however, the
five-year period will be extended for additional one-year periods, until 700
site proposals are submitted to the Proposed BAM JV. The Proposed BAM JV will
be required to build towers in the general vicinity of the locations proposed
by BAM. Upon completion of a tower, it will become subject to the Global Lease
(as discussed below). Space not leased by BAM or its affiliates on each tower
is available for lease by the Proposed BAM JV to third parties.

The Build-to-Suit Agreement sets out various time periods for BAM to
identify its tower needs within certain search areas, and for the Proposed BAM
JV to locate sites and to thereafter complete site acquisition and development
work, including permitting and construction.

Global Lease

In connection with the formation of the Proposed BAM JV, BAM and the
Proposed BAM JV will enter into the Global Lease. All of the approximately
1,427 towers to be acquired by the Proposed BAM JV from BAM and the
Transferring Partnerships pursuant to the Formation Agreement, and all towers
constructed by the Proposed BAM JV pursuant to the Build-to-Suit Agreement,
will be governed by the Global Lease. The average monthly rent paid by BAM on
each of the 1,427 towers contributed to the Proposed BAM JV by BAM will be
approximately $1,850. Minimum monthly rents on the towers built pursuant to the
Build-to-Suit Agreement will range from $1,250 to $1,833 depending on the
region in which the tower is located. These rents may increase based on the
amount of BAM's equipment to be installed at a site. Rents are subject to
annual increase based on the consumer price index, subject to certain
adjustments. For all sites, the initial lease term is ten years. BAM has the
right to extend any lease for three additional five-year terms and one
additional term of four years and eleven months. Each lease will automatically
renew for an option term unless BAM notifies the Proposed BAM JV at least six
months before the then current term expires. Space not leased by BAM or its
affiliates on each tower is available for lease by the Proposed BAM JV to third
parties.

98
<PAGE>

Operating Agreements

In connection with the formation of the Proposed BAM JV, BAM and CCAIC will
enter into limited liability company operating agreements that will establish
and govern the limited liability companies comprising the Proposed BAM JV.

Governance. The business and affairs of the Proposed BAM JV will be managed
by its managers under the supervision of a board of representatives. Each
manager will be selected by CCAIC. Members of the board of representatives will
be selected by each of BAM and CCAIC in proportion to their ownership interests
in the Proposed BAM JV. The board of representatives initially will have six
members, with two selected by BAM and four selected by CCAIC. So long as BAM
maintains at least a 5.0% interest in the Proposed BAM JV, it will maintain the
right to designate at least one member of the board of representatives.

The managers will operate the Proposed BAM JV on a day-to-day basis. In
general, the managers will have the power and authority to take all necessary
or appropriate actions to conduct the Proposed BAM JV's business in accordance
with its then current business plan. Actions requiring the approval of the
board of representatives generally will be authorized upon the affirmative vote
of a majority of the members of the board of representatives. However, the
following actions will require the mutual consent of BAM and CCAIC, either by
written consent or by the approval of representatives of each of BAM and CCAIC
at a meeting of the board of representatives:

. engaging in any business other than owning, acquiring, constructing,
leasing and operating communications towers in the United States;

. taking any voluntary action that would cause the Proposed BAM JV to be
insolvent or voluntarily entering into a bankruptcy proceeding;

. incurring any debt other than the Proposed BAM JV Credit Facility and
ordinary course trade payables;

. incurring any liens;

. issuing any additional equity interests in the Proposed BAM JV;

. becoming liable with respect to contingent obligations such as
guarantees or the obligation to make take-or-pay or similar payments;

. failing to preserve the Proposed BAM JV's existence under Delaware law
or its qualification to do business in each jurisdiction in which such
qualification is necessary or desirable;

. mergers or consolidations;

. sales of assets outside the ordinary course;

. entry into contracts with affiliates except in the ordinary course and
on an arm's-length basis;

. any dividends or distributions; provided, if the Proposed BAM JV has
been dissolved and the Proposed BAM JV Credit Facility has been repaid
in full, BAM's consent will not be required;

. the determination of the methodology to be used in calculating payments
under the management agreement and the services agreement pursuant to
which the Company will manage and provide services to the Proposed BAM
JV;

. approval of the business plan;

. entry into contracts that (1) restrict the business activities of the
Proposed BAM JV in any geographic area, (2) contain exclusivity
provisions, (3) are inconsistent with any of the

99
<PAGE>

agreements entered into in connection with the formation of the Proposed
BAM JV or (4) provide for the purchase or sale of goods or services
involving an amount in excess of $10.0 million per year; and

. exercising any voting rights with respect to the shares of common stock
of the Company held by the Proposed BAM JV; provided, if BAM and CCAIC
do not agree as to how the shares should be voted, the shares will be
voted pro rata with all shares of common stock of the Company voted on
the matter.

Restrictions on Transfers of Interests; Rights of First Refusal; Tag-Along
Rights. Except for transfers to wholly owned affiliates, neither BAM nor
CCAIC may transfer its interest in the Proposed BAM JV to a third party unless
it first offers its interest to the other on terms and conditions, including
price, no less favorable than the terms and conditions on which it proposes to
sell its interest to the third party. In addition, if BAM or CCAIC wishes to
transfer its interest in the Proposed BAM JV to a third party, the other party
will have the right to require the third party, as a condition to the sale, to
purchase a pro rata portion of its interest in the Proposed BAM JV on the same
terms and conditions, including price. BAM may only transfer its 0.001%
interest in the operating subsidiary of the Proposed BAM JV to its wholly
owned affiliates or in connection with a merger or consolidation transaction
to which BAM or Bell Atlantic Corporation is a party.

Dissolution of the Proposed BAM JV. We have agreed with BAM that upon a
dissolution of the Proposed BAM JV, in satisfaction of our respective
interests in the Proposed BAM JV, we would receive all the assets and
liabilities of the Proposed BAM JV other than the approximately 15.6 million
shares of our common stock held by the Proposed BAM JV and BAM would receive
all of the shares of our common stock held by the Proposed BAM JV and a
payment from us, equal to 14.0% of the fair market value of the assets and
liabilities of the joint venture (other than our common stock), to be made in
cash or our common stock (at our election). BAM would continue to retain its
0.001% interest in the joint venture's operating subsidiary. For so long as it
retains such interest, the operations formerly included in the Proposed BAM JV
would remain subject to the operating restrictions set forth under "--
Governance". A dissolution of the Proposed BAM JV may be triggered (1) by BAM
at any time following the third anniversary of the formation of the Proposed
BAM JV and (2) by us at any time following the fourth anniversary of its
formation; however, if the we trigger the dissolution prior to the seventh
anniversary, we may be required to make additional cash payments to BAM.

Transitional Services Agreement; Services Agreement

In connection with the formation of the Proposed BAM JV, BAM and the
Proposed BAM JV are expected to enter into a transitional services agreement
pursuant to which BAM will provide the Proposed BAM JV with services necessary
to ensure a smooth transition of the business to the Proposed BAM JV. In
addition, we and the Proposed BAM JV are expected to enter into the services
agreement pursuant to which we will provide the Proposed BAM JV with certain
services.

Proposed BellSouth Transaction

On March 5, 1999, we entered into the Letter Agreement with BellSouth
Mobility Inc., BellSouth Telecommunications Inc. and certain of its
affiliates. Subject to approval by BellSouth's Board of Directors, the Letter
Agreement sets forth the terms of our agreement under which BellSouth will
sell to us, in a taxable sale pursuant to a master sublease agreement, their
1,850 wireless communications towers for $610.0 million, consisting of $430.0
million in cash and approximately 9.1 million shares of our common stock
(valued at $180.0 million), subject to adjustments. The aggregate
consideration will be subject to increase if BellSouth transfers more than
1,850 towers to us in connection with the transaction.

100
<PAGE>

We will be responsible for managing, maintaining and leasing the available
space on BellSouth's wireless communications towers located throughout Indiana,
Kentucky, Louisiana, Mississippi, Alabama, Arkansas, Florida, Georgia and
Tennessee. While we will have complete responsibility for the towers, and their
monitoring and maintenance, BellSouth will continue to fully own its
communications components including switching equipment, shelters and cell site
facilities. BellSouth will pay a fee of $1,200 per month per site to us for its
services on existing and build-to-suit towers.

The transaction is expected to close in a series of closings, beginning in
the second quarter of 1999, and is expected to be fully closed no later than
eight months thereafter. In connection with our entering into the Letter
Agreement we have placed $50.0 million in an escrow account which will be
returned to us at the first stage of the multi-stage closing. There can be no
assurance, however, that the Proposed BellSouth Transaction will be consummated
on the terms described in this document or at all. See "Risk Factors--We May
Not Consummate the Proposed Transactions."

The following description of the agreements related to the Proposed
BellSouth Transaction are summaries of the material portions of those
agreements. These descriptions are qualified in their entirety by reference to
the complete text of the agreements, each of which is available as set forth
under the heading "Available Information".

Letter Agreement

General. Pursuant to the Letter Agreement, a newly formed subsidiary of
ours, that we call CCSI, will receive rights to lease, sublease, design,
develop, contract, operate, market and manage approximately 1,850 tower sites
owned by BellSouth Mobility Inc., BellSouth Telecommunications Inc. and certain
of BellSouth's affiliates, or to be constructed on behalf of BellSouth, in
Indiana, Kentucky, Louisiana, Mississippi, Alabama, Arkansas, Florida, Georgia
and Tennessee, which we call the Territory, in exchange for aggregate
consideration of $610.0 million, consisting of $430.0 million in cash and
approximately 9.1 million shares of our common stock (valued at $180.0
million), subject to adjustments.

The terms and conditions of the sublease of the 1,850 sites by BellSouth to
CCSI are set forth in an agreement, which we call the Sublease, to be entered
into between BellSouth and CCSI and us. Further, we have agreed to enter into a
site management agreement, which we call the Site Management Agreement,
pursuant to which we will agree to provide certain management services on sites
which are not part of the 1,850 towers contemplated by the Sublease, because of
restrictions on transfer, and which will be designated by BellSouth. The Letter
Agreement further contemplates a build-to-suit agreement to be entered into by
BellSouth and CCSI pursuant to which CCSI will develop and construct at least
500 towers in the Territory over a period of five years, which period will be
extended for an additional two-year period in the event CCSI has not completed
at least 500 tower builds within the initial five-year time period.

The Letter Agreement provides that the transaction will require further
documentation including the preparation, acceptance and delivery of a
definitive agreement to sublease, which we call the Agreement to Sublease, the
terms of which have not yet been fully negotiated.

Consideration. Pursuant to the Letter Agreement, we will pay to BellSouth
the sum of $324,324.32 for each site leased or subleased to CCSI pursuant to
the Sublease. In the event that subleases covering the full 1,850 towers are
transferred to CCSI as contemplated by the Letter Agreement, the aggregate
consideration payable to BellSouth will consist of $430.0 million in cash and
$180.0 million in our common stock; provided, however, that we will retain the
option to increase the cash portion of the aggregate consideration by up to
$30.0 million and decrease the equity portion to not less than $150.0 million.
Such option must be exercised by us prior to the first

101
<PAGE>

closing. The number of shares of our common stock included in the consideration
will be approximately 9.1 million shares and was determined using the average
closing price of our common stock on the 30 trading days immediately preceding
March 5, 1999, which we call the Initial Share Price. While the Letter
Agreement contemplates the sublease by BellSouth of approximately 1,850 sites
to CCSI, in the event that additional sites are subleased to CCSI, the
consideration paid for the next 250 sites will be payable in cash only. If CCSI
subleases more than 2,100 sites from BellSouth in connection with the Sublease,
consideration for any additional towers will be payable in shares of our common
stock.

The Letter Agreement further provides that if the average closing price of
our common stock during the 30 day period immediately preceding the first
anniversary of the final closing which we call the Subsequent Share Price is
less than the Initial Share Price, then we will, at our option, (1) pay
BellSouth cash in an amount, which we call the Make-up Amount, equal to (x) the
difference between the Initial Share Price and the Subsequent Share Price
multiplied by (y) the number of shares issued as part of the consideration less
(z) the gross proceeds from all sales of such shares prior to the first
anniversary of the final closing or (2) issue to BellSouth the number of shares
of our common stock equal to the Make-up Amount divided by the Subsequent Share
Price; in each case not to exceed $50.0 million in cash or $75.0 million in
common stock.

Pursuant to the Letter Agreement, the consideration will be subject to
adjustment based on the amount we are required to pay in calendar year 1999 for
ground rent on sites contemplated by the Letter Agreement. If a post-closing
audit demonstrates that the amount we are required to pay, in aggregate, for
such ground rents exceeds $11.4 million, BellSouth will be required to pay to
CCSI an amount equal to a certain multiple of the amount by which the rents
exceed $11.4 million, not to exceed $45.0 million.

Escrow Payment. In connection with the signing of the Letter Agreement, we
deposited the amount of $50.0 million into an escrow account which we call the
BellSouth Escrow Payment. Upon approval of the Proposed BellSouth Transaction
by BellSouth's Board of Directors, BellSouth will be entitled to receive the
BellSouth Escrow Payment in full in the event that:

. we and BellSouth fail to execute the Agreement to Sublease within 90
days of the date of the Letter Agreement (and BellSouth has negotiated
the operative documents in good faith) or

. the Agreement to Sublease is executed but the initial closing fails to
occur as a result of any breach of the Agreement to Sublease by us or
CCSI or any failure of us or CCSI to satisfy the closing conditions set
forth in the Agreement to Sublease.

Upon consummation of the first closing, the BellSouth Escrow Payment will
be returned to us. Further, if BellSouth's Board of Directors fails to approve
the Proposed BellSouth Transaction within the applicable time period, the
BellSouth Escrow Payment will be returned to us. BellSouth has agreed to seek
the approval of its Board of Directors as soon as practicable, but no later
than April 26, 1999.

In the event that BellSouth's Board of Directors does not approve the
Proposed BellSouth Transaction within 90 days of the Letter Agreement, and if
at any time within one year following expiration or termination of the Letter
Agreement BellSouth transfers, sells, assigns, leases, subleases or otherwise
disposes of all or substantially all of the tower assets contemplated by the
Letter Agreement, BellSouth will be required to pay to us an amount equal to
the greater of (i) $15.0 million or (ii) one-half of the amount by which the
total consideration received by BellSouth pursuant to such transfer, sale,
assignment, lease or sublease exceeds the total consideration that would have
been paid to BellSouth by us pursuant to the Letter Agreement.

102
<PAGE>

Closings. In connection with the Letter Agreement, we and BellSouth have
agreed that the sublease of the sites pursuant to the Sublease will be
consummated in a series of closings not to
exceed a period of eight months and will include a minimum number of sites to
be included in each closing, the first of which is expected to take place on
May 31, 1999. BellSouth has agreed to use all commercially reasonable efforts
to sublease approximately 250 sites at each closing, grouped so as to be
located in contiguous regions, until all sites have been subleased prior to or
at the final closing. The sites to be included on the initial closing date will
be located in Kentucky and Indiana.

Termination Right. The Letter Agreement provides that in the event that any
one of the closings contemplated by the Proposed BellSouth Transaction is not
consummated due to our or TowerCo's failure to comply with all conditions,
covenants and representations required of them, in addition to any other
remedies BellSouth may have at equity or law, BellSouth will have the right to
require us to pay to BellSouth a termination fee of $50.0 million which we call
the Termination Fee, to terminate all agreements between the parties, and at
BellSouth's option, to rescind all prior closings. If BellSouth elects to
rescind the prior closings, payment of the Termination Fee shall be made by
netting it against the amounts previously paid to BellSouth at the previous
closings, and BellSouth shall return to us any amount which is in excess of the
Termination Fee.

Sublease

Pursuant to the Letter Agreement, the parties fully and completely agreed
upon the terms of the Sublease.

General. Pursuant to the terms of the Sublease, BellSouth has agreed to
grant a lease to CCSI, pursuant to which CCSI will lease (or sublease) the
land, tower and improvements which we call the Subleased Property at each site
other than certain space reserved by BellSouth and space utilized by third
parties under existing subleases. BellSouth has agreed to lease to CCSI all its
sites in the Territory except where it is legally prohibited from doing so and
except for sites that are specifically excluded from the Sublease. BellSouth
expects that the number of sites available for sublease will be approximately
1,850. The sites constructed pursuant to the Build to Suit Agreement, as
described below, will also be made part of and subject to the Sublease.

Pursuant to the Sublease, CCSI will be entitled to use the Subleased
Property of each site for constructing, installing, operating, managing,
maintaining and marketing the tower and improvements on each site, including
leasing space to third party tenants. BellSouth has agreed to pay CCSI a site
maintenance charge of $1,200 per month per site, subject to an increase of five
percent (5%) per year for the first ten (10) years following the applicable
commencement date of the sublease on such site. If, after the tenth anniversary
following each commencement date, the then current site maintenance charge is
below the market rate, then such site maintenance charge will automatically be
increased on such anniversary and each anniversary thereafter by the consumer
price index ("CPI"). If the then site maintenance charge is above the market
rate, then such site maintenance charge will be automatically reset at ninety
percent (90%) of such agreed upon market rate and will increase on each
following anniversary by the then current annual market rate of increase for
comparable properties. CCSI has agreed to pay as rent to BellSouth the ground
rents relating to each site that is leased by BellSouth, and rent of $1.00 per
year for sites that are owned by BellSouth. In addition, CCSI has agreed to
sublease available space to any party to existing colocation agreements with
BellSouth; provided that CCSI will receive all rents and other economic
benefits from the parties to such colocation agreements.

Term. The term of the Sublease will be one hundred (100) years for sites
owned by BellSouth and, for sites leased by BellSouth, one day less than the
term of the underlying ground lease. CCSI will be responsible for negotiating
and obtaining extensions or renewals of the ground leases. In

103
<PAGE>

addition, if CCSI is able to acquire a fee simple interest in a site, CCSI has
agreed to transfer such fee simple interest to BellSouth for $1.00, in which
event CCSI will pay no ground rent as of the date fee simple title vests in
BellSouth.

Reserved Space. Under the Sublease, BellSouth has reserved space which we
call the Reserved Space on each site. The Reserved Space generally relates to
the portion of the site, including space on the tower, in use by BellSouth and
its affiliates. In certain circumstances and subject to certain conditions
described in the Sublease, BellSouth has the right to increase the number of
antennas on its reserved space to twelve (12), without increasing the related
site maintenance payment, on up to one hundred twenty (120) towers. BellSouth
also has the right to substitute the Reserved Space for other available space
on the tower, as well as a right of first refusal and right of substitution as
to available space which CCSI intends to sublease to any third party.

If BellSouth ceases using its Reserved Space on a site and elects to
assign, sublet or otherwise transfer the interest in the Reserved Space on such
site, CCSI will have the right to, at any time, acquire BellSouth's interest in
the applicable Reserved Space by paying to BellSouth consideration of (1)
$5,000 (subject to increase based on the CPI) plus (2) a grant to BellSouth of
the right to receive up to thirty-five percent (35%) of all gross revenues
payable to CCSI in respect of such Reserved Space.

BellSouth will have the right to put to CCSI its rights in its Reserved
Space with respect to a site, and thereby add such space to the Sublease;
provided that the number of sites subject to such a put right may not exceed
the greater of one and one half percent (1 1/2%) or thirty (30) of the total
sites. In such event, BellSouth will assign to CCSI all its rights in the
Reserved Space on that site and will thereafter no longer be responsible for
the related site maintenance charge.

Withdrawal Right. After the tenth anniversary of the first closing,
BellSouth will have the right, subject to certain notice requirements, to
withdraw its rights on any site. In such case, BellSouth will assign to CCSI
all its rights, including the ground lease and any Reserved Space, with respect
to any withdrawn site and shall no longer be responsible for the related site
maintenance charge.

Termination. The Sublease may be terminated by each party in the event of
certain breaches by the other party, including the failure to timely make
required payments under the Sublease, breaches of covenants and other
agreements in the Sublease, breaches of representations and warranties and
insolvency. In the case of BellSouth's right to terminate, BellSouth may
terminate the Sublease as to an applicable site following a breach (and failure
to cure) relating to that particular site. BellSouth may terminate the entire
Sublease upon the occurrence of unwaived defaults by CCSI in respect of more
than fifty (50) sites during any consecutive five-year period.

Build to Suit Agreement

In connection with the Letter Agreement, BellSouth agreed to enter into the
Build to Suit Agreement with us and CCSI pursuant to which CCSI will develop
and construct all towers built in the Territory on behalf of BellSouth for a
period of five years. If CCSI has not constructed at least 500 towers over the
five year period following the signing of the Build to Suit Agreement, the term
of the Build to Suit Agreement will be extended for up to an additional two
years until such time as CCSI has constructed 500 towers. BellSouth will be
required, pursuant to the Build to Suit Agreement, to submit to CCSI all
proposals to develop and construct tower sites within the Territory until CCSI
has completed construction of 500 towers. CCSI will be required to develop and
construct tower sites in locations that satisfy BellSouth's engineering
requirements. Upon substantial

104
<PAGE>

completion of a tower site, the site will become subject to and part of the
Sublease. The Build to Suit Agreement will provide that space not reserved by
BellSouth on each tower will be available for lease by CCSI to third parties.

Site Maintenance Agreement

In connection with the Agreement to Sublease, the parties will enter into a
Site Maintenance Agreement whereby CCSI will perform certain identified
services at those sites in the Territory which are not leased or subleased to
CCSI pursuant to the Sublease and which sites are designated by BellSouth for
inclusion in the Site Maintenance Agreement. Pursuant to the Letter Agreement,
we and BellSouth have agreed that BellSouth will pay to us a site maintenance
fee of $333.00 per site per month, increased annually by the CPI, for sites
designated under the Site Maintenance Agreement. Further, the parties have
agreed that the total number of sites to be covered by the Site Management
Agreement will not exceed 100 sites.

Site Marketing Agreement

On March 25, 1998, we and BellSouth entered into the Site Marketing
Agreement pursuant to which we market BellSouth's sites located in Kentucky. In
connection with the Letter Agreement, we agreed to renew the Site Marketing
Agreement, the term of which ended on February 15, 1999, and to extend the
scope of the agreement to include the entire Territory.

Registration Rights Agreement

As a condition to the Letter Agreement, we have agreed to enter into a
registration rights agreement whereby we will grant to BellSouth certain demand
and piggyback registration rights in respect of shares of our common stock we
pay to BellSouth as consideration for the Proposed BellSouth Transaction.

Proposed Powertel Acquisition

On March 15, 1999, we and CCP Inc., our wholly owned indirect subsidiary,
entered into the Asset Purchase Agreement with Powertel, Inc. and five of its
subsidiaries, which we refer to collectively as Powertel, pursuant to which the
parties agreed that we would purchase from Powertel approximately 650 towers
and related assets and liabilities.

We will pay to Powertel aggregate consideration of $275.0 million, which we
refer to below as the Purchase Price, (subject to adjustment based on the
amount of towers actually tendered to us at closing) for the 650 towers. At
closing, Powertel will pay us a credit against the purchase price in an
aggregate amount of $383,000.00, which we call the Purchase Price Credit, as
consideration for our acceptance of certain towers containing site leases which
may require revenue received from Powertel or its affiliates to be shared with
the site lessors. We call the Purchase Price less the Purchase Price Credit,
the Closing Price. Pursuant to the Asset Purchase Agreement, we have placed
$50.0 million in escrow to be applied to the Closing Price. In the event that
Powertel has fulfilled all conditions precedent to closing and we are unable or
unwilling to deliver the balance of the Closing Price, Powertel will receive up
to the full $50.0 million as liquidated damages. See"--Asset Purchase
Agreement", "--Escrow Agreement" and "Risk Factors--We May Not Consummate the
Proposed Transactions".

Pursuant to the Asset Purchase Agreement, at closing Powertel will assign
and we will assume five master site agreements, which we call the Master Site
Agreements, pursuant to which Powertel will agree to pay us monthly rent of
$1,800 per tower for continued use of space Powertel or its affiliates occupies
on the towers. This per tower amount is subject to increase on each fifth
anniversary of the agreement and as Powertel adds equipment to these towers.

105
<PAGE>

Although the Proposed Powertel Acquisition is expected to be consummated on
or before June 4, 1999, the Asset Purchase Agreement is subject to a number of
significant conditions. There can be no assurance that the Proposed Powertel
Acquisition will be consummated on the terms described in this document or at
all. See "Risk Factors--We May Not Consummated the Proposed Transactions".

The following descriptions of the agreements related to the Proposed
Powertel Acquisition are summaries of the material portions of those
agreements. These descriptions are qualified in their entirety by reference to
the complete text of the agreements, each of which is available as set forth
under the heading "Available Information".

Asset Purchase Agreement

Purchase Price. Pursuant to the Asset Purchase Agreement, we will pay the
Closing Price in cash on or before June 4, 1999, which we refer to as the
Closing Date, to Powertel for Powertel's tower structures, rights to tower
sites, related assets and rights under applicable governmental permits. The
purchase price is subject to adjustment up or down based on the actual number
of sites tendered at closing. The Asset Purchase Agreement provides that sites
considered defective or incomplete, which we call "Rejected Sites", will not be
tendered at closing, and consequently, the purchase price will be reduced by an
amount equal to $423,077 for each Rejected Site.

Terms and Conditions. In connection with the Proposed Powertel Acquisition,
we and Powertel are making certain representations and warranties which must be
true on the Closing Date in order for the transaction to be consummated. Other
conditions which must be satisfied on the Closing Date include:

. compliance by us and Powertel with the Asset Purchase Agreement;

. absence of litigation;

. receipt of regulatory approvals; and

. absence of any material adverse effect with respect to the Powertel
assets and assumed liabilities.

In addition, pursuant to the Asset Purchase Agreement, we have deposited
$50.0 million in cash, which we refer to as the Escrow Deposit, with SunTrust
Bank Atlanta, which we refer to as the Escrow Agent. At closing, the Escrow
Deposit will be delivered to Powertel and credited against the Closing Price.
However, we have agreed that the Escrow Deposit will be forfeited to Powertel
in the event that we are unable to receive adequate financing to consummate the
acquisition and thus are unable to close the acquisition in a timely manner. As
a condition to the Asset Purchase Agreement, we have agreed to use our
reasonable best efforts to have a registration statement relating to such
financing declared effective as expeditiously as possible. Further, upon the
occurrence of certain events, we are required to provide Powertel with adequate
written assurance that we have at least one alternative financing source, which
in Powertel's sole judgment provides it assurance that we will have on hand a
minimum of an additional $225.0 million in cash to apply to the Purchase Price
at closing. We refer to this as a Financing Assurance. Such Financing Assurance
must be received by Powertel within five days of the occurrence of certain
events including:

. our failure to file the registration statement before March 19, 1999;

. the withdrawal or abandonment of the registration statement or the
decision not to proceed with the offerings;

. our failure to commence presentations to institutional investors by May
15, 1999 or, after commencement of such presentations, termination or
abandonment of such presentations and failure to proceed to pricing of
the offerings.

106
<PAGE>

In the event we are required to provide Powertel with a Financing
Assurance, Powertel will have five days to accept or reject it. If Powertel
rejects the Financing Assurance, we will have ten days from receipt of the
rejection to deliver the $225.0 million balance of the Closing Price to the
Escrow Agent, who will deliver the entire Closing Price to Powertel at closing.
However, if we are unable or unwilling to deliver the additional sum into
escrow, Powertel will have the right to unilaterally terminate the Asset
Purchase Agreement, and receive, as its sole remedy, from the Escrow Deposit
liquidated damages in the amount of $10.0 million on or prior to May 15, 1999
or $25.0 million after May 15, 1999 but prior to June 4, 1999. If on June 4,
1999, Powertel has fulfilled all of its obligations and conditions precedent to
closing in all material respects and has not defaulted or breached its
obligations under the Asset Purchase Agreement, and we have failed to deliver
the additional sum into escrow or are otherwise unable or unwilling to deliver
the Purchase Price, Powertel will receive as liquidated damages the entire
amount of the Escrow Deposit.

Master Site Agreement

On the Closing Date, the parties to the Asset Purchase Agreement and
certain of Powertel's affiliates will enter into Master Site Agreements
governing all towers acquired pursuant to the Asset Purchase Agreement.
Pursuant to the Master Site Agreements, Powertel or certain affiliates will
agree to continue to lease the space it currently occupies on the towers to be
acquired by us. The monthly rent paid by Powertel for each tower will be
$1,800. Such monthly payment is subject to increase based on an agreed upon
schedule if and when Powertel adds equipment to a site. Nonetheless, the
monthly rent, including additional rents related to the addition of certain
equipment, shall be increased on each fifth anniversary of the agreement up to
an amount that is 115% of the rent paid during the preceding five year period.
The Master Site Agreements provide that space not occupied by Powertel on the
acquired towers can be leased to third parties at our sole option.

Pursuant to the Master Site Agreements, the term of each tower lease will
be ten years. Powertel has the right to extend any site lease for up to three
additional five year periods. Each site lease will automatically renew for an
option term unless Powertel notifies us of its intent not to renew at least 180
days prior to the end of the then current term.

Proposed One2One Transaction

On March 5, 1999, we entered into an agreement, which we call the Framework
Agreement, with One2One, pursuant to which CTI has agreed to manage, develop
and, at its option, acquire up to 821 towers. These towers represent
substantially all the towers in One2One's 1,800 MHz nationwide wireless network
in the United Kingdom. Approximately one-half of these 821 towers can
accommodate additional tenants. We expect to upgrade or replace the other
towers as demand for space on such towers arises. We believe that the cost of
upgrading or replacing any single tower will not exceed $40,000.

CTI will be responsible for managing and leasing available space on the
towers, and will receive all the income from any such third party leases. The
term of the management arrangements will be up to 25 years. During the three-
year period following the closing, CTI will have the right, at its option, to
acquire for (Pounds)1.00 per site One2One's interest in the 821 towers, to the
extent such interests can be assigned. One2One has also agreed to include as
part of the Framework Agreement, including CTI's right to acquire sites during
the three-year period, any new One2One towers constructed during the term of
the agreement.

Framework Agreement

Terms and Conditions. The 821 existing towers will be managed by CTI
pursuant to a management contract with an initial term of 10 years, which is
extendable at CTI's option for an

107
<PAGE>

additional 15 years. CTI will also assume all liabilities in connection with
the 821 existing towers. During the three-year period following the closing,
which we call the Option Period, One2One will assign to CTI, at CTI's option,
One2One's interest in the sites on which the 821 existing towers are located.
For sites where the underlying ground lease is not assignable, the management
contract will continue in effect. CTI also has the right during the Option
Period to assume ownership of any new One2One towers which are built by or for
One2One during the Option Period.

Consideration. As consideration for the Framework Agreement, One2One will
receive varying rent-free periods of site use depending on the type of tower
site as follows:

. The 821 existing towers. One2One will enter into a 25 year site sharing
agreement with CTI permitting One2One to continue to occupy the 821
existing towers. This agreement will be rent-free until March 2007 (with a
retroactive adjustment to April 1998). After the expiration of this initial
period, One2One will pay to CTI an annually indexed rental fee (based on
(Pounds)3,750.0 per site index adjusted from 1999) plus a further
additional compensatory payment to CTI in the event that CTI is chosen as
the contractor with respect to fewer than 250 new One2One sites. See "--
One2One ADC Contract".

. New One2One sites. One2One will also enter into 25 year site sharing
agreements with CTI to occupy all new One2One towers and pay CTI an
annually indexed rental fee (based on (Pounds)4,000.0 per site index
adjusted from 1999) after an initial rent-free period of fifteen years.

. 166 CTI towers currently under lease by One2One. One2One currently
occupies 166 CTI sites under a master lease agreement. This master lease
will be modified to allow One2One to occupy these sites rent-free from
April 1998 until March 2000.

The Framework Agreement is conditional upon the approvals of both One2One
and CTI's board of directors and senior creditors.

One2One ADC Contract

In connection with the Framework Agreement, CTI entered into a separate
contract with One2One, which we refer to as the ADC Contract, under which CTI
will provide acquisition, design and construction services for up to 250 new
One2One sites. If One2One requests CTI's services with respect to all 250
sites, CTI will be paid aggregate fees in excess of (Pounds)7.0 million. CTI
also believes that some of the new sites will be new builds, which are known as
greenfield sites, under the Framework Agreement, and thus CTI will be eligible
to assume ownership of these greenfield sites following their construction,
pursuant to the terms of the Framework Contract.

Severance Agreements

The Company has entered into severance agreements (the "Severance
Agreements") with Messrs. Miller, Ivy, Green, Gwyn, Rees, Reese and Hawk (the
"Executives"). Pursuant to the Severance Agreements, the Company is required to
provide severance benefits to the Executives if they are terminated by the
Company without Cause (as defined in the Severance Agreements) or the
Executives terminate with Good Reason (as defined in the Severance Agreements)
(collectively, a "Qualifying Termination"). The Severance Agreements provide
for enhanced severance benefits if the Executives incur a Qualifying
Termination within the two-year period following a Change in Control (as
defined in the Severance Agreements) of the Company (the "Change in Control
Period"). Upon a Qualifying Termination that does not occur during the Change
in Control Period, an eligible Executive is entitled to (i) a lump sum payment
equal to two times the sum of his base salary and annual bonus, (ii) continued
coverage under specified welfare benefit programs for two years and (iii)
immediate vesting of any outstanding options and restricted stock awards. Upon
a Qualifying Termination during the Change in Control Period, an eligible
Executive is entitled to (i) receive a lump sum payment equal to three times
the sum of his base salary and annual bonus, (ii) continued coverage under
specified welfare benefit programs for three years and (iii) immediate vesting
of any outstanding options and restricted stock awards.

Crown Arrangements

The Company and Mr. Crown have entered into a Memorandum of Understanding
and a related Services Agreement. Pursuant to the Services Agreement, Mr. Crown
has agreed to continue to serve in a consulting capacity to (and as Chairman
of) CCI for a two-year period expiring on December 9, 2000, and the Company has
agreed, for such two-year period, to pay Mr. Crown cash compensation of
$300,000 annually, along with certain executive perquisites. At the end of such
two-year period, the Company will pay Mr. Crown a severance benefit of
$300,000. At the time of entering to the Memorandum of Understanding, the
Company also agreed to vest all of Mr. Crown's

115
<PAGE>

existing stock options; to immediately grant Mr. Crown options to purchase
50,000 shares of common stock at $7.50 per share; and, upon the closing of the
IPO, to grant Mr. Crown options to purchase 625,000 shares of common stock at
the price to public in the IPO ($13.00 per share).

Stock Option Plans

1995 Stock Option Plan

The Company has adopted the 1995 Stock Option Plan, which was reamended on
July 1, 1998 (the "1995 Stock Option Plan"). The purpose of the 1995 Stock
Option Plan is to advance the interests of the Company by providing additional
incentives and motivations which help the Company to attract, retain and
motivate employees, directors and consultants. The description set forth below
summarizes the general terms of the 1995 Stock Option Plan and the options
granted pursuant to the 1995 Stock Option Plan.

Pursuant to the 1995 Stock Option Plan, the Company can grant options to
purchase up to 18,000,000 shares of common stock. Options granted under the
1995 Stock Option Plan may either be incentive stock options ("ISOs") under
Section 422 of the Code or nonqualified stock options. The price at which a
share of common stock may be purchased upon exercise of an option granted under
the 1995 Stock Option Plan will be determined by the Board of Directors and, in
the case of nonqualified stock options, may be less than the fair market value
of the common stock on the date that the option is granted. The exercise price
may be paid in cash, in shares of common stock (valued at fair market value at
the date of exercise), in option rights (valued at the excess of the fair
market value of the common stock at the date of exercise over the exercise
price) or by a combination of such means of payment, as may be determined by
the Board.

Employees, directors or consultants of the Company (including its
subsidiaries and affiliates) are eligible to receive options under the 1995
Stock Option Plan (although only certain employees are eligible to receive
ISOs). The 1995 Stock Option Plan is administered by the Board and the Board is
authorized to interpret and construe the 1995 Stock Option Plan. Subject to the
terms of the 1995 Stock Option Plan, the Board is authorized to select the
recipients of options from among those eligible, to establish the number of
shares that may be issued under each option and to take any actions
specifically contemplated or necessary or advisable for the administration of
the 1995 Stock Option Plan.

No options may be granted under the 1995 Stock Option Plan after July 31,
2005, which is ten years from the date the 1995 Stock Option Plan was
originally adopted and approved by the Board and stockholders of the Company.
The 1995 Stock Option Plan will remain in effect until all options granted
under the 1995 Stock Option Plan have been exercised or expired. The Board, in
its discretion, may terminate the 1995 Stock Option Plan at any time with
respect to any shares of common stock for which options have not been granted.
The 1995 Stock Option Plan may be amended by the Board without the consent of
the stockholders of the Company, other than as to a material increase in
benefits, an increase in the number of shares that may be subject to options
under the 1995 Stock Option Plan or a change in the class of individuals
eligible to receive options under the 1995 Stock Option Plan. However, no
change in any option previously granted under the 1995 Stock Option Plan may be
made which would impair the rights of the holder of such option without the
approval of the holder.

Pursuant to the 1995 Stock Option Plan, options are exercisable during the
period specified in each option agreement or certificate; provided, however,
that no option is exercisable later than ten years from the date the option is
granted. Options generally have been exercisable over a period of ten years
from the grant date and vested in equal installments over a four or five year
period of service with the Company as an employee. A change in control
generally accelerates the vesting of

116
<PAGE>

options granted to employees and some of the options vest upon the achievement
of specific business goals or objectives. An option generally must be exercised
within 12 months of a holder ceasing to be involved with the Company as an
employee, director or consultant as a result of death and within three months
if the cessation is for other reasons; however, these periods can be extended
by decision of the Board (other than in the case of an ISO). Shares of common
stock subject to forfeited or terminated options again become available for
option awards. The Board may, subject to certain restrictions in the 1995 Stock
Option Plan (and, in the case of an ISO, in Section 422 of the Code), extend or
accelerate the vesting or exercisability of an option or waive restrictions in
an option agreement or certificate.

The 1995 Stock Option Plan provides that the total number of shares covered
by the 1995 Stock Option Plan, the number of shares covered by each option, and
the exercise price per share under each option will be proportionately adjusted
in the event of a recapitalization, stock split, dividend, or a similar
transaction.

No grant of any option will constitute realized taxable income to the
grantee. Upon exercise of a nonqualified option, the holder will recognize
ordinary income in an amount equal to the excess of the fair market value of
the stock received over the exercise price paid therefor and the tax basis in
any shares of common stock received pursuant to the exercise of such option
will be equal to the fair market value of the shares on the exercise date if
the exercise price is paid in cash. The Company will generally have a deduction
in parity with the amount realized by the holder. The Company has the right to
deduct and withhold applicable taxes relating to taxable income realized by the
holder upon exercise of a nonqualified option and may withhold cash, shares or
any combination in order to satisfy or secure its withholding tax obligation.
An ISO is not subject to taxation as income to the employee at the date of
grant or exercise and the Company does not get a business deduction as to an
ISO; provided, the stock is not sold within two years after the ISO was granted
and one year after the ISO was exercised. The ISO is effectively taxed at
capital gain rates upon the sale of the stock by the employee. However, if the
stock acquired upon exercise of an ISO is sold within two years of the ISO
grant date or one year exercise of the date, then it is taxed the same as a
Nonqualified Option. Upon the exercise of an ISO, the difference between the
value of the stock and the exercise price is recognized as a preference item
for alternative minimum tax purposes.

As of December 31, 1998, options to purchase a total of 13,082,220 shares
of common stock have been granted. Options for 572,825 shares of common stock
have been exercised, options for 282,750 shares have been forfeited and options
for 12,226,645 shares remain outstanding. The outstanding options are for (i)
345,000 shares with an exercise price of $0.40 per share, (ii) 43,750 shares
with an exercise price of $1.20 per share, (iii) 50,000 shares with an exercise
price of $1.60 per share, (iv) 175,000 shares with an exercise price of $2.40
per share, (v) 5,385 shares with an exercise price of $3.09 per share, (vi)
5,385 shares with an exercise price of $4.03 per share, (vii) 1,630,625 shares
with an exercise price of $4.20 per share, (viii) 23,135 shares with an
exercise price of $4.76 per share, (ix) 5,385 shares with an exercise price of
$5.24 per share, (x) 28,000 shares with an exercise price of $5.97 per share;
(xi) 107,200 shares with an exercise price of $6.00 per share, (xii) 5,633,030
shares with an exercise price of $7.50 per share, (xiii) 28,000 shares with an
exercise price of $7.77 per share, (xiv) 28,000 shares with an exercise price
of $10.08 per share, (xv) 75,000 shares with an exercise price of $11.31 per
share, (xvi) 75,000 shares with an exercise price of $11.50 per share, (xvii)
125,000 shares with an exercise price of $11.94 per share, (xviii) 253,750
shares with an exercise price of $12.50 per share and (xix) 3,590,000 shares
with an exercise price of $13.00 per share. The options exercisable at $0.40
per share are fully vested and held by Ted B. Miller, Jr. Vested and
exercisable options also include options for (i) 43,750 shares at $1.20 per
share, (ii) 50,000 shares at $1.60 per share, (iii) 175,000 shares at $2.40 per
share, (iv) 1,463,625 shares at $4.20 per share, (v) 23,135 shares at $4.76 per
share, (vi) 107,200 shares at $6.00 per share, (vii) 2,805,630 shares at $7.50
per share, (viii) 128,750 shares at $12.50 per share

117
<PAGE>

and (ix) 90,000 shares at $13.00 per share. Except for the options for 23,135
shares with an exercise price of $4.76 per share and options for 3,036,250
shares with an exercise price of $7.50, the exercise prices for all of the
options were equal to or in excess of the estimated fair value of the common
stock at the dates on which the numbers of shares and the exercise prices were
determined; as such, in accordance with the "intrinsic value based method" of
accounting for stock options, the Company did not recognize compensation cost
related to the grant of these options. The options for 23,135 shares with an
exercise price of $4.76 were issued in 1998 in exchange for services received
from nonemployees; as such, the Company will account for the issuance of these
options in 1998 based on the fair value of the services received. Options for
3,036,250 shares granted at an exercise price of $7.50 per share (which is
below the estimated fair market value at the date of grant) were included in
the group of options which vested at the consummation of the initial public
offering of common stock. The Company will account for these options in 1998
based upon the fair market value of services received. The remaining options
for 2,731,230 shares granted at an exercise price of $7.50 per share (which is
below the estimated fair market value at the date of grant) were granted in
1998 and generally are taken into account and vest over five years. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Compensation Charges Related to Stock Option Grants".

Between January 1, 1998 and December 31, 1998, the Company granted to its
executive officers and directors options for a total of 2,240,500 shares at an
exercise price of $7.50 and 3,235,000 shares at an exercise price of $13.00
under the 1995 Stock Option Plan. Mr. Miller received options for 928,000
shares, Mr. Ivy received options for 560,000 shares, Mr. Green received options
for 425,000 shares, Mr. Gwyn received options for 75,000 shares, Mr. Rees
received options for 90,000 shares, Mr. Crown received options for 137,500
shares and Mr. McKenzie received 25,000 shares, in each case at an exercise
price of $7.50 per share. Mr. Miller received options for 1,035,000 shares, Mr.
Ivy received options for 545,000 shares, Mr. Green received options for 515,000
shares, Mr. Gwyn received options for 175,000 shares, Mr. Rees received options
for 250,000 shares, Mr. Crown received options for 625,000 shares, Messrs.
Ferenbach, Hack and Schutz each received options for 25,000 shares and Messrs.
Azibert, Chetaille and Murphy each received options for 5,000 shares, in each
case at an exercise price of $13.00 per share.

The options granted include ISOs for 627,750 shares with an exercise price
of $7.50 per share. As of December 31, 1998, ISOs for 81,250 shares have been
forfeited and none of the outstanding ISOs are exercisable.

CTSH Stock Option Plans

CTSH has established certain stock option plans for the benefit of its
employees (the "CTSH Stock Option Plans"). Upon consummation of the Roll-Up in
August 1998, all of the outstanding options to purchase shares of capital stock
of CTSH ("CTSH Options") granted pursuant to the CTSH Stock Option Plans were
converted into and replaced by options to purchase shares of the Company's
common stock ("CCIC Options"). The Company's Board of Directors has adopted
each of the CTSH Option Plans. Options granted under the CTSH Stock Options
Plans may be adjusted at the discretion of the Company or, in the case of
options granted under the CTSH Share Bonus Plan (as defined), the CTSH Trustee
(as defined) to take into account any variation of the share capital of the
Company subject to the written confirmation of the auditors of the Company that
the adjustment in their opinion is fair and reasonable. The description set
forth below summarizes the general terms of each of the various plans that
constitute the CTSH Stock Options Plans.

Included in CTI's operating expenses for the nine months ended September
30, 1998 are noncash compensation charges for (Pounds)2.5 million ($4.2
million) related to the issuance of stock options to certain executives and
employees.

be exercised in full and on one occasion. Outstanding options granted pursuant
to the CTSH All Employee Plan will lapse if not exercised by the earlier of (i)
the first anniversary of the option holder's death, (ii) six months following
the termination of the option holder's employment with the Company, (iii) six
months following the earlier of (a) a change of control of the Company, (b) the

been paid by each participant. No additional options will be granted under the
CTSH All Employee Plan in the future.

Plan will lapse on the earlier of (i) the first anniversary of the option
holder's death, (ii) six months after the termination of the option holder's
employment with the Company (other than a termination for cause, or the
voluntary resignation of the option holder), (iii) immediately upon any other

option holder being adjudicated bankrupt under U.K. law, (vi) the surrender of

shares of common stock at prices ranging from (Pounds)1.43 ($2.39) to
(Pounds)6.04 ($10.08) per share. No additional options will be granted under
the CTSH Management Plan in the future.

CTSH Bonus Share Plan. In connection with the Castle Transmission Services
(Holdings) Ltd. Bonus Share Plan (the "CTSH Bonus Share Plan"), CTSH has
executed the Employee Benefit Trust (the "CTSH Trust"), a discretionary
settlement for the benefit of past and present CTI employees, directors and
their families. CTI employees and directors are able to participate in the CTSH
Bonus Share Plan by foregoing a portion of their annual bonuses awarded by the
Company in consideration for options to purchase shares of the Company's common
stock held by the CTSH Trust at predetermined prices per share depending upon
the year in which the investment is made. The predetermined price for 1997
investment was (Pounds)13.00 ($21.70) per unit (each of which will be converted
into seven shares of common stock upon consummation of the Roll-Up), and the
CTI board has determined that the predetermined price for any investment in
1998 and 1999 will be (Pounds)16.90 ($28.21) and (Pounds)21.97 ($36.68)
respectively.

All outstanding options granted pursuant to the CTSH Bonus Share Plan are
vested and may be exercised in whole or in part at the discretion of the option
holder prior to the lapsing of the

119
<PAGE>

option. All options will lapse on the earlier of (i) the first anniversary of
the option holder's death, (ii) six months after the termination of the option
holder's employment with the Company, (iii) six months following a Corporate
Event, (iv) the option holder being adjudicated bankrupt under U.K. law, (v)
the surrender of the option or (vi) the seventh anniversary of the grant of the
option. In order to satisfy the demand created by the exercise of options
granted pursuant to the CTSH Bonus Share Plan, the CTSH Trustee has been
granted a call option by the Company ("the U.K. Option Agreement") to purchase
up to 149,709 shares of common stock from the Company at a price of
(Pounds)1.86 ($3.11) per share, the funds for which are to be contributed to
the CTSH Trust by CTSH (which has already provided for such payment in its
financial statements). Currently there are outstanding options to purchase
149,709 shares of common stock from the CTSH Trustee for a nominal sum upon
exercise. Following the Offering, CTI employees and directors will continue to
be able to effectively invest a proportion of their annual bonuses in common
stock of the Company under the CTSH Bonus Share Plan for the fiscal years 1998
and 1999. Thereafter, no additional options will be granted under the CTSH
Share Bonus Plan. Grants under the CTSH Bonus Share Plan are determined by
converting monetary awards into options to purchase shares at predetermined
prices.

CTSH Option Grants to Certain Executives. In January and April of 1998,
CTSH granted options to purchase a total of 300,000 ordinary shares and
299,700,000 preference shares of CTSH to Ted B. Miller, Jr., David L. Ivy and

exercise price of (Pounds)1.43 and 210,000 shares of the Company's common stock
at an exercise price of (Pounds)3.57. Upon the Roll-Up, the exercise prices

determine to sell or transfer 2% or more of the voting securities then issuable
or outstanding to a third party who is not an affiliate of any of the
Initiating Stockholders, the other Stockholders would have the opportunity and
the right to sell to the purchasers in such proposed transfer (upon the same
terms and conditions as the Initiating Stockholders) up to that number of
Shares owned by such Stockholder equaling the product of (i) a fraction, the
numerator of which is the number of Shares owned by such Stockholder as of the
date of such proposed transfer and the denominator of which is the aggregate
number of Shares owned

by the Initiating Stockholders and by all Stockholders exercising tag-along

CTSH Shareholders' Agreement

On August 21, 1998, CCIC, TdF and CTSH entered into a Shareholders'
Agreement to govern the relationship between CCIC and TdF as Shareholders of
CTSH (the "CTSH Shareholders' Agreement").

Corporate Governance. The CTSH Shareholders' Agreement provides that the
Board of CTSH shall be comprised of six directors, of which CCIC and TdF will
each have the right to appoint and remove two directors with the remaining two
directors to be mutually agreed upon by CCIC and TdF. CCIC has the right to
nominate the chairman, chief executive officer, chief operating officer and
chief financial officer of CTSH, subject to approval buy a super majority vote
of the Board of CCIC.

The affirmative vote of a majority of the Board, including a director
nominated by CCIC and a director nominated by TdF, is necessary for the
adoption of a resolution. Further, the prior written consent of each of CCIC
and TdF, in their capacities as shareholders, is required for the following
actions, among others, significant acquisitions and dispositions; issuance of
new shares; entry into transactions with shareholders, except pursuant to the
CTI Services Agreement and/or the CTI Operating Agreement; entry into new lines
of business; capital expenditures outside the budget; entry into banking and
other financing facilities; entry into joint venture arrangements; payment of
dividends, except for (1) dividends payable in respect of CTSH's redeemable
preferred shares and (2) dividends permitted by CTSH's financing facilities;
and establishing a public market for CTSH shares. Similar governance
arrangements also apply to CTSH's subsidiaries.

If either CCIC or TdF vetoes a transaction (either at Board or shareholder
level), the other shareholder is entitled to pursue that transaction in its own
right and for its own account.

Transfer Provisions. Subject to certain exceptions, neither CCIC nor TdF
may transfer any interest in shares held in CTSH to a third party. Transfers of
shares to affiliated companies are permitted, subject to certain conditions. No
shares may be transferred if such transfer would (1) entitle the BBC to
terminate either of the BBC contracts, (2) subject CTSH to possible revocation
of its licenses under the Telecommunications Act 1984 or the Wireless
Telegraphy Acts 1949, 1968 and 1998 or (3) cause CCIC or TdF to be in breach of
the Commitment Agreement between the Company, TdF, TdF Parent and the BBC
(under which the Company and TdF have agreed to maintain certain minimum
ownership levels in CTSH for a period of five years). See "Business--U.K.
Operations--Significant Contracts--BBC Commitment Agreement".

In addition, shares may be sold to a third party, subject to a right of
first refusal by the other party, after the later of (1) the second anniversary
of the closing of the Roll-up, and (2) the expiration of the period for the
completion of the TdF Put Right (as defined) or the Company Call Right (as
defined). If CCIC purchases TdF's shares pursuant to such right of first
refusal, it may elect (instead of paying the consideration in cash) to
discharge the consideration by issuing its common stock at a discount of 15% to
its market value. If the right of first refusal is not exercised, the selling
shareholder must procure and offer on the same terms for the shares held by the
other party. If the Company elects to issue common stock to TdF pursuant to the
right of first refusal, TdF will be entitled to certain demand registration
rights and tag along rights.

TdF Put Right. TdF has the right to put its shares of CTSH to CCIC for cash
(the "TdF Put Right") if there is a change of control of CCIC. Such right is
exercisable if (1) TdF has not exchanged

128
<PAGE>

its shares pursuant to the Governance Agreement by the second anniversary of
the closing of the Roll-Up, or (2) prior to the second anniversary of the
closing of the Roll-Up, if TdF has ceased to be Qualified for the purposes of
the Governance Agreement.

The consideration payable on the exercise of the TdF Put Right will be an
amount agreed between CCIC and TdF or, in the absence of agreement, the fair
market value as determined by an independent appraiser.

TdF Exit Right. TdF also has the right after the earlier of (1) the second
anniversary of the closing of the Roll-Up, or (2) TdF ceasing to be Qualified
for purposes of the Governance Agreement, to require CCIC, upon at least six
months' notice, to purchase all, but not less than all, of the shares it
beneficially owns in CTSH (the "TdF Exit Right").

The consideration to be paid to TdF, and the manner in which it is
calculated, upon exercise of the TdF Exit Right is substantially the same as
described upon exercise of the TdF Put Right.

CCIC is entitled to discharge the consideration payable on the exercise of
the TdF Exit Right either in cash or by issuing common stock to TdF at a
discount of 15% to its market value. If CCIC elects to issue common stock to
TdF on the exercise of the TdF Exit Right, TdF will be entitled to certain
demand registration rights and tag-along rights.

CCIC Deadlock Right. CCIC has the right to call TdF's shares of CTSH,
subject to certain procedural requirements, for cash if, after the third
anniversary of the closing of the Roll-Up, TdF refuses on three occasions
during any consecutive six-month period to agree to the undertaking by CTSH of
certain types of transactions (including acquisitions and disposals) that would
fall within CTSH's core business (the "CCIC Deadlock Right"). The consideration
due on the exercise of the CCIC Deadlock Right is payable in cash, the fair
market value of the TdF interest to be determined in the same manner described
above upon exercise of the TdF Put or Exit Rights.

CCIC Shotgun Right. Provided that TdF has not, pursuant to the Governance
Agreement, exchanged its share ownership in CTSH for shares of CCIC, CCIC may
(1) by notice expiring on August 21, 2003, or (2) at any time within 45 days of
CCIC becoming aware of a TdF Change of Control (as defined in the Governance
Agreement) offer to purchase TdF's shares in CTSH. TdF is required to either
sell its shares or agree to purchase CCIC's shares in CTSH at the same price
contained in CCIC's offer for TdF's shares of CTSH.

The consummation of any transfer of shares between CCIC and TdF pursuant to
any of the transfer provisions described above is subject to the fulfillment of
certain conditions precedent, including obtaining all necessary governmental
and regulatory consents.

Termination. The Shareholders' Agreement terminates if either CCIC or TdF
ceases to be qualified. CCIC remains qualified on the condition that it holds
at least 10% of the share capital of CTSH.

CTI Services Agreement

On February 28, 1997, CTI and TdF Parent entered into a Services Agreement
(the "CTI Services Agreement") pursuant to which TdF Parent agreed to provide
certain consulting services to CTI in consideration for a minimum annual fee of
(Pounds)400,000 ($667,800) and reimbursement for reasonable out-of-pocket
expenses. TdF Parent has agreed to, among other things, provide the services of
ten executives or engineers to CTI on a part-time basis and to provide a
benchmarking review of CTI. In addition, TdF Parent has agreed to provide
additional services relating to research, development and professional training
on terms (including as to price) to be determined. Following

129
<PAGE>

February 28, 2003, the CTI Services Agreement will be terminable on 12-month's
prior notice given by CTI to TdF.

CTI Operating Agreement

The following summary of the terms of the CTI Operating Agreement is
subject to the negotiation of definitive documentation, although the Company
expects such agreement to have the general terms described herein. Under the
CTI Operating Agreement (the "CTI Operating Agreement"), the Company will be
permitted to develop business opportunities relating to terrestrial wireless
communications (including the transmission of radio and television
broadcasting) anywhere in the world except the United Kingdom. CTI will be
permitted to develop such business opportunities solely in the United Kingdom.
The Company and TdF also intend to establish, pursuant to the CTI Operating
Agreement, a joint venture to develop digital terrestrial transmission services
in the United States. See "Business--U.S. Operations--Network Services--
Broadcast Site Rental and Services".

The CTI Operating Agreement will also establish a framework for the
provision of business support and technical services to the Company and its
subsidiaries (other than CTI) in connection with the development of any
international business by the Company. TdF will have the right, if called upon
to do so by the Company or CTSH, to provide all or part of such services to the
Company and its subsidiaries (other than CTI) in connection with the provision
of broadcast transmission services.

DESCRIPTION OF CAPITAL STOCK

The following summary does not purport to be complete and is subject to the
detailed provisions of, and qualified in its entirety by reference to, the
Certificate of Incorporation, the Certificate of Designations, the By-laws, the
Governance Agreement, the CTSH Shareholders Agreement and the Stockholders'
Agreement, and to the applicable provisions of the Delaware General Corporation
Law (the "DGCL").

General

The authorized capital stock of the Company consists of 600,000,000 shares
of common stock, par value $.01 per share), 90,000,000 shares of Class A Common
Stock, par value $.01 per share (the "Class A Common Stock"), and 10,000,000
shares of Preferred Stock, par value $.01 per share. There are 94,905,902
shares of common stock outstanding, 11,340,000 shares of Class A Common Stock
outstanding, and 201,063 shares of 12 3/4% Senior Exchangeable Preferred Stock
due 2010.

Common Stock

Voting Rights

Each share of common stock is entitled to one vote. The common stock votes
together as a single class on all matters presented for a vote of the
stockholders, except as provided under the DGCL. All the outstanding shares of
common stock are held by directors, executive officers, other employees and
affiliates of the Company or its subsidiaries.

Dividends

Each share of common stock is entitled to receive dividends if, as and when
declared by the Board of Directors out of funds legally available therefor,
subject to approval of certain holders of the Senior Convertible Preferred
Stock.

Liquidation Rights

In the event of the dissolution of the Company, after satisfaction of
amounts payable to creditors and distribution to the holders of outstanding
Senior Convertible Preferred Stock, if any, of amounts to which they may be
preferentially entitled, holders of common stock are entitled to share ratably
in the assets available for distribution to the stockholders.

Other Provisions

There are no preemptive rights to subscribe for any additional securities
which the Company may issue, and there are no redemption provisions or sinking
fund provisions applicable to the common stock. All outstanding shares of
common stock are legally issued, fully paid and nonassessable.

Class A Common Stock

Voting Rights

Each share of Class A Common Stock is entitled to one vote for each such
share on all matters presented to the stockholders, except with respect to the
election of directors. The holders of the shares of Class A Common Stock vote,
except as provided under the DGCL, together with the holders of the common
stock and any other class or series of stock of the Company accorded such
general voting rights, as a single class.

134
<PAGE>

So long as TdF is Qualified, holders of shares of Class A Common Stock
voting as a separate class have the right to elect two directors to the Board
of Directors of the Company; provided, however, that if TdF is not Qualified,
so long as the ownership interest of the TdF Group is at least 5%, holders of
Class A Common Stock voting as a separate class have the right to elect one
director.

The holders of Class A Common Stock, subject to certain limitations
described in "The Roll-Up--Governance Agreement--Governance Limitations", have
a Veto over certain significant actions, described in "Governance--Veto
Rights", taken by the Company.

Convertibility

Each share of Class A Common Stock is convertible, at the option of its
record holder, into one share of common stock at any time.

In the event of any transfer of any share of Class A Common Stock to any
Person other than an Affiliate (as defined in Rule 12b-2 of the Exchange Act),
such share of Class A Common Stock automatically converts, without any further
action, into one share of common stock; provided, however, and subject to
certain conditions described in the Certificate of Incorporation, that a holder
of shares of Class A Common Stock may pledge such holder's shares to a
financial institution pursuant to a bona fide pledge of such shares of Class A
Common Stock as collateral security for any indebtedness or other obligation of
any Person due to the pledgee or its nominee.

Further, each share of Class A Common Stock automatically converts into one
share of common stock on the first date on which the ownership interest of TdF
Group is less than 5%.

Other Provisions

Pursuant to the Governance Agreement, so long as it remains Qualified, TdF
has anti-dilutive rights in connection with maintaining a certain percentage of
voting power in the Company and, accordingly, the Company may not, subject to
certain exceptions relating primarily to compensation of directors and
employees, issue, sell or transfer additional securities (except for the IPO)
unless TdF is offered the right to purchase, at the same price, an amount such
that it would maintain such percentage of voting power in the Company. All
outstanding shares of Class A Common Stock are legally issued, fully paid and
nonassessable.

Preferred Stock

Pursuant to the Certificate of Incorporation, the Company may issue up to
10,000,000 shares of Preferred Stock in one or more series. The Board of
Directors has the authority, without any vote or action by the stockholders
(other than any rights of TdF under the Governance Agreement), to create one or
more series of Preferred Stock up to the limited of the Company's authorized
but unissued shares of Preferred Stock and to fix the designations,
preferences, rights, qualifications, limitations and restrictions thereof,
including the voting rights, dividend rights, dividend rate, conversion rights,
terms of redemption (including sinking fund provisions), redemption price or
prices, liquidation preferences and the number of shares constituting any
series. See "Risk Factors--Anti-Takeover Provisions".

Senior Exchangeable Preferred Stock

Exchangeable Preferred Stock

$1,000 per share and is exchangeable, at the option of the Company, in whole
but not in part, for its 12 3/4% Senior Subordinated Exchange Debentures due
2010.

135
<PAGE>

Voting Rights

The shares of Exchangeable Preferred Stock have no voting rights, except as
required by law and as specified in the Certificate of Designations. In the
event that the Company fails to meet its obligations under the Certificate of
Designations, the holders of the Exchangeable Preferred Stock will be entitled
to elect two additional members to the Board of Directors.

Dividends

Dividends are paid on each March 15, June 15, September 15 and December 15
commencing March 15, 1999, at an annual fixed rate of 12 3/4%. On or before
December 15, 2003, the Company has the option to pay dividends in cash or in
additional fully paid and non-assessable shares of Exchangeable Preferred Stock
having an aggregate liquidation preference equal to the amount of such
dividends. After December 15, 2003, dividends will be paid only in cash.

Mandatory Redemption

The Company is required to redeem all of the shares of Exchangeable
Preferred Stock outstanding on December 15, 2010 at a redemption price equal to
100% of the liquidation preference of such shares, plus accumulated and unpaid
dividends to the date of redemption.

Optional Redemption

On or after December 15, 2003, the Company may redeem some or all of the
shares of Exchangeable Preferred Stock at any time at certain specified
redemption prices. In addition, before December 15, 2001, the Company may
redeem up to 35% of the Exchangeable Preferred Stock with the proceeds of
certain public equity offerings or strategic equity investments at a redemption
price equal to 112.750% of the liquidation preference of the Exchangeable
Preferred Stock, together with accumulated and unpaid dividends.

Change of Control

If the Company experiences specific kinds of changes in control, it will be
required to make an offer to purchase any and all shares of Exchangeable
Preferred Stock at a purchase price of 101% of the liquidation preference of
such shares together with all accumulated and unpaid dividends.

Certain Covenants

The Exchangeable Preferred Stock was issued under a Certificate of
Designations that became part of the Company's Certificate of Incorporation.
The Certificate of Designations contains certain covenants that, among other
things, limit our ability and the ability of certain of the Company's
subsidiaries to borrow money; pay dividends on stock or purchase capital stock;
make investments and sell assets or merge with or into other companies.

Ranking

The Exchangeable Preferred Stock ranks (1) senior to all other classes of
capital stock of the Company established after the issue date of the
Exchangeable Preferred Stock that do not expressly provide that they rank on a
parity with the Exchangeable Preferred Stock as to dividends and distributions
upon the liquidation, winding up and dissolution of the Company and (2) on a
parity with any class of capital stock established after the date of issuance
of the Exchangeable Preferred Stock the terms of which provide that such class
or series will rank on a parity with the Exchangeable Preferred Stock as to
dividends and distributions upon the liquidation, winding up and dissolution of
the Company.

In connection with the offering of the Senior Convertible Preferred Stock
in August 1997 and October 1997, the Company issued warrants to purchase an
aggregate of 1,314,990 shares of common stock at a price of $7.50 per share.

Certificate of Incorporation and By-laws

Stockholders' rights and related matters are governed by the DGCL, the
Certificate of Incorporation and the By-laws. Certain provisions of the
Certificate of Incorporation and By-laws, which are summarized below, may have
the effect, either alone or in combination with each other, of discouraging or
making more difficult a tender offer or takeover attempt that is opposed by the
Company's Board of Directors but that a stockholder might consider to be in its
best interest. Such provisions may also adversely affect prevailing market
prices for the common stock. The Company believes that such provisions are
necessary to enable the Company to develop its business in a manner that will
foster its long-term growth without disruption caused by the threat of a
takeover not deemed by the Board of Directors to be in the best interests of
the Company and its stockholders.

Classified Board of Directors and Related Provisions

The Certificate of Incorporation provides that the directors of the
Company, other than those directors who may be elected by holders of any series
of Preferred Stock or holders of the Class A Common Stock, initially are to be
divided into three classes of directors, initially consisting of three, three
and four directors. One class of directors, initially consisting of three
directors, will be elected for a term expiring at the annual meeting of
shareholders to be held in 1999, another class initially consisting of three
directors will be elected for a term expiring at the annual meeting of
stockholders to be held in 2000, and another class initially consisting of four
directors shall be initially elected for a term expiring at the annual meeting
of stockholders in 2001. The classified board provisions will prevent a party
who acquires control of a majority of the outstanding Voting Stock of the
Company from obtaining control of the Board of Directors until the second
annual stockholders meeting following the date such party obtains the
controlling interest. The provisions of the Certificate of Incorporation
relating to the classified nature of the Company's Board of Directors may not
be amended without the affirmative vote of the holders of at least 80% of the
voting power of the Company's outstanding Voting Stock. "Voting Stock" is
defined in the Certificate of Incorporation as the outstanding shares of
capital stock of the Company entitled to vote in a general vote of stockholders
of the Corporation as a single class with shares of common stock of the
Company, which shares of capital stock include the shares of Class A Common
Stock.

No Stockholder Action by Written Consent; Special Meeting

The Certificate of Incorporation prohibits stockholders (other than holders
of Class A Common Stock with respect to matters upon which such holders are
entitled to vote as a separate class) from taking action by written consent in
lieu of an annual or special meeting and, thus, stockholders may only take
action at an annual or special meeting called in accordance with the By-laws.
The By-laws provide that special meetings of stockholders may only be called by
the Secretary of the Company at the direction of the Board of Directors
pursuant to a resolution adopted by the Board.

These provisions could have the effect of delaying consideration of a
stockholder proposal until the next annual meeting. The provisions would also
prevent the holders of a majority of the voting power of the capital stock of
the Company entitled to vote from unilaterally using the written consent
procedure to take stockholder action.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

The By-laws establish advance notice procedures with regard to stockholder
proposals and the nomination, other than by or at the direction of the Board of
Directors, of candidates for election as directors. These procedures provide
that the notice of stockholder proposals and stockholder nominations for the
election of directors at an annual meeting must be in writing and received by
the Secretary no less than 90 days nor more than 120 days prior to the first
anniversary of the preceding year's annual meeting; provided, however, that
with respect to the annual meeting to be held in 1999, the anniversary date
shall be deemed to be April 1, 1999; provided further that in the event that
the date of the annual meeting is advanced by more than 30 days, or delayed by
more than 90 days, from such anniversary date, notice by the stockholder to be
timely must be delivered not earlier than the 120th day prior to such annual
meeting and not later than the close of business on the later of the 90th day
prior to such annual meeting or the 10th day following the day on which public
disclosure of the date of the annual meeting was made. The notice of
nominations for the election of directors must set forth certain information
with respect to the stockholder giving the notice and with respect to each
nominee.

By requiring advance notice of nominations by stockholders, the foregoing
procedures will afford the Board of Directors an opportunity to consider the
qualifications of the proposed nominees and, to the extent deemed necessary or
desirable by the Board of Directors, to inform stockholders about such
qualifications. By requiring advance notice of other proposed business, such
procedures will provide the Board of Directors with an opportunity to inform
stockholders, prior to such meetings, of any business proposed to be conducted
at such meetings, together with any recommendations as to the Board of
Directors' position regarding action to be taken with respect to such business,
so that stockholders can better decide whether to attend such a meeting or to
grant a proxy regarding the disposition of any such business.

Dilution

The Certificate of Incorporation provides that the Board of Directors is
authorized to create and issue, whether or not in connection with the issuance
and sale of any of its stock or other securities or property, rights entitling
the holders to purchase from the Company shares of stock or other securities of
the Company or any of other corporation, recognizing that, under certain
circumstances, the creation and issuance of such rights could have the effect
of discouraging third parties from seeking, or impairing their right to seek,
to acquire a significant portion of the outstanding securities of the Company,
to engage in any transaction which might result in a change of control of the
corporation or to enter into any agreement, arrangement or understanding with
another party to accomplish the foregoing or for the purpose of acquiring,
holding, voting or disposing of any securities of the Company.

Indemnification

The Certificate of Incorporation and By-laws provide that the Company shall
indemnify each director or officer of the Company to the fullest extent
permitted by law.

Amendments

The Certificate of Incorporation and By-laws provide that the Company may
at any time and from time to time, amend, alter, change or repeal any provision
contained in the Certificate of Incorporation or a Preferred Stock designation;
provided, however, the affirmative vote of the holders of at least 80% of the
voting power of the then outstanding Voting Stock, voting together as a single
class, is required to amend, repeal or adopt any provision inconsistent with
certain provisions of the Certificate of Incorporation, including the
provisions referred to above relating to the classification of

138
<PAGE>

the Board of Directors, prohibiting stockholder action by written consent, and
prohibiting the calling of special meetings by stockholders.

The By-laws may be amended by either the holders of 80% of the voting power
of the Voting Stock or by the majority of the Board; provided that the Board
may alter, amend or repeal or adopt new By-laws in conflict with certain
provisions thereof by a two-thirds vote of the entire Board.

Rights Plan

Rights

The Board of Directors of the Company has declared a dividend of one right
(the "Rights") for each outstanding share of common stock and each outstanding
share of Class A Common Stock. The Rights will be issued to the holders of
record of common stock and Class A Common Stock outstanding on the date of the
consummation of the IPO (the "Issuance Date"), and with respect to common stock
and Class A Common Stock issued thereafter until the Distribution Date (as
defined below), and, in certain circumstances, with respect to common stock and
Class A Common Stock issued after the Distribution Date. Each Right, when it
becomes exercisable as described below, will entitle the registered holder to
purchase from the Company one one-thousandth (1/1000th) of a share of Series A
Participating Cumulative Preferred Stock (the "Preferred Shares") at a price of
$110.00 per (1/1000th) of a share, subject to adjustment in certain
circumstances (the "Purchase Price"). The description and terms of the Rights
are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and the Rights Agent named therein. The Rights will not be exercisable
until the Distribution Date and will expire on the tenth annual anniversary of
the Rights Agreement (the "Expiration Date"), unless earlier redeemed by the
Company. Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends with respect to the Rights or the
Preferred Shares relating thereto.

Distribution Date

Under the Rights Agreement, the Distribution Date is the earlier of (i)
such time as the Company learns that a person or group (including any affiliate
or associate of such person or group) has acquired, or has obtained the right
to acquire, beneficial ownership of more than 15% of the outstanding voting
securities of the Company (such person or group being an "Acquiring Person"),
subject to the exceptions relating to the TDF Group and the Berkshire Group
described in the paragraph below, unless provisions preventing accidental
triggering of the distribution of the Rights apply, and (ii) the close of
business on such date, if any, as may be designated by the Board of Directors
following the commencement of, or first public disclosure of an intent to
commence, a tender or exchange offer for more than 15% or more of the
outstanding shares of Voting Securities.

Each member of the TdF Group will not otherwise be considered an Acquiring
Person if (a) during the first five years following the adoption of the Rights
Agreement, the aggregate ownership interest of the TdF Group does not exceed
25% (or 30% if the Board so elects) of the outstanding Voting Securities or (b)
thereafter, the aggregate ownership interest of the TdF Group does not exceed
the lesser of (i) 25% or 30%, as applicable, of the Voting Securities then
outstanding and (ii) the greater of (x) the aggregate interest of the TdF Group
as of the fifth anniversary of the Rights Agreement and (y) 15% of the then
outstanding Voting Securities. Each member of the Berkshire Group will not
otherwise be deemed an Acquiring Person if the aggregate ownership interest of
the Berkshire Group does not exceed the greater of (a) the aggregate ownership
interest of the Berkshire Group upon the execution of the Rights Agreement,
reduced by an amount equal to any disposition of Voting Securities following
the date the Rights Agreement is executed and (b) 15% of the outstanding Voting
Securities.

139
<PAGE>

Triggering Event and Effect of Triggering Event

At such time as there is an Acquiring Person, the Rights will entitle each
holder (other than such Acquiring Person) of a Right to purchase, at the
Purchase Price, that number of one-thousandths (1/1000ths) of a Preferred Share
equivalent to the number of shares of common stock that at the time of such
event would have a market value of twice the Purchase Price.

In the event the Company is acquired in a merger or other business
combination by an Acquiring Person or an affiliate or associate of an Acquiring
Person that is a publicly traded corporation or 50% or more of the Company's
assets or assets representing 50% or more of the Company's revenues or cash
flow are sold, leased, exchanged or otherwise transferred (in one or more
transactions) to an Acquiring Person or an affiliate or associate of an
Acquiring Person that is a publicly traded corporation, each Right will entitle
its holder (other than Rights beneficially owned by such Acquiring Person or
its affiliates or associates) to purchase, for the Purchase Price, that number
of common shares of such corporation which at the time of the transaction would
have a market value or, in certain circumstances, book value of twice the
Purchase Price. In the event the Company is acquired in a merger or other
business combination by an Acquiring Person or an affiliate or associate of an
Acquiring Person that is not a publicly traded entity or 50% or more of the
Company's assets or assets representing 50% or more of the Company's revenues
or cash flow are sold, leased, exchanged or otherwise transferred (in one or
more transactions) to an Acquiring Person or affiliate or associate of an
Acquiring Person that is not a publicly traded entity, each right will entitle
its holder (subject to the next paragraph) to purchase, for the Purchase Price,
at such holder's option, (i) that number of shares of the surviving corporation
in the transaction with such entity (which surviving corporation could be the
Company) which at the time of the transaction would have a book value of twice
the Purchase Price, (ii) that number of shares of the ultimate parent of or
entity controlling such surviving corporation which at the time of the
transaction would have a book value of twice the Purchase Price or (iii) if
such entity has an affiliate which has publicly traded common shares, that
number of common shares of such affiliate which at the time of the transaction
would have market value of twice the Purchase Price.

Any Rights that are at any time beneficially owned by an Acquiring Person
(or any affiliate or associate of an Acquiring Person) will be null and void
and nontransferable and any holder of any such right (including any purported
transferee or subsequent holder) will be unable to exercise or transfer any
such Right.

Redemption

At any time prior to the earlier of (i) such time as a person or group
becomes an Acquiring Person and (ii) the Expiration Date, the Board of
Directors may redeem the Rights in whole, but not in part, at a price (in cash
or common stock or other securities of the Company deemed by the Board of
Directors to be at least equivalent in value) of $.01 per Right (which amount
shall be subject to adjustment as provided in the Rights Agreement) (the
"Redemption Price"). Immediately upon the action of the Board of Directors
ordering the redemption of the Rights, and without any further action and
without any notice, the right to exercise the Rights will terminate and the
only right of the holders of Rights will be to receive the Redemption Price.

In addition, at any time after there is an Acquiring Person, the Board of
Directors may elect to exchange each Right for consideration per Right
consisting of one-half of the securities that would be issuable at such time
upon exercise of one Right pursuant to the terms of the Rights Agreement.

Amendment

At any time prior to the Distribution Date, the Company may, without the
approval of any holder of any Rights, supplement or amend any provision of the
Rights Agreement (including, without

140
<PAGE>

limitation, the date on which the Expiration Date or Distribution Date shall
occur, the definition of Acquiring Person, the time during which the Rights may
be redeemed or the terms of the Preferred Shares), except that no supplement or
amendment shall be made which reduces the Redemption Price (other than pursuant
to certain adjustments therein).

Certain Effects of the Rights Plan

The Rights plan is designed to protect stockholders of the Company in the
event of unsolicited offers to acquire the Company and other coercive takeover
tactics which, in the opinion of the Board of Directors, could impair its
ability to represent stockholder interests. The provisions of the Rights Plan
may render an unsolicited takeover of the Company more difficult or less likely
to occur or might prevent such a takeover, even though such takeover may offer
the Company's stockholders the opportunity to sell their stock at a price above
the prevailing market rate and may be favored by a majority of the stockholders
of the Company.

Section 203 of the Delaware General Corporation Law

Section 203 of the DGCL prohibits certain transactions between a Delaware
corporation and an "interested stockholder", which is defined as a person who,
together with any affiliates and/or associates of such person, beneficially
owns, directly or indirectly, 15% or more of the outstanding voting shares of a
Delaware corporation. This provision prohibits certain business combinations
(defined broadly to include mergers, consolidations, sales or other
dispositions of assets having an aggregate value of 10% or more of the
consolidated assets of the corporation, and certain transactions that would
increase the interested stockholder's proportionate share ownership in the
corporation) between an interested stockholder and a corporation for a period
of three years after the date the interested stockholder acquired its stock,
unless: (i) the business combination is approved by the corporation's Board of
Directors prior to the date the interested stockholder acquired shares; (ii)
the interested stockholder acquired at least 85% of the voting stock of the
corporation in the transaction in which it became an interested stockholder; or
(iii) the business combination is approved by a majority of the Board of
Directors and by the affirmative vote of two-thirds of the outstanding voting
stock owned by disinterested stockholders at an annual or special meeting. A
Delaware corporation, pursuant to a provision in its certificate of
incorporation or by-laws, may elect not to be governed by Section 203 of the
DGCL. The Certificate of Incorporation does not exclude the Company from the
restrictions imposed by Section 203 of the DGCL and, as a result, the Company
will be subject to its provisions upon consummation of the IPO.

Under certain circumstances, Section 203 of the DGCL makes it more
difficult for a person who could be an "interested stockholder" to effect
various business combinations with a corporation for a three-year period,
although the stockholders may elect to exclude a corporation from the
restrictions imposed thereunder. The Certificate of Incorporation of the
Company does not exclude the Company from the restrictions imposed under
Section 203 of the DGCL. It is anticipated that the provisions of Section 203
of the DGCL may encourage companies interested in acquiring the Company to
negotiate in advance with the Board of Directors, since the stockholder
approval requirement would be avoided if a majority of the directors then in
office approves, prior to the date on which a stockholder becomes an interested
stockholder, either the business combination or the transaction which results
in the stockholder becoming an interested stockholder.

Limitations of Directors' Liability

The Certificate of Incorporation provides that no director of the Company
will be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director except for liability: (1)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (2) for acts of omissions not in good faith or which involve
intentional misconduct or a

141
<PAGE>

knowing violation of law, (3) under Section 174 of the DGCL, or (4) for any
transaction from which the director derived an improper personal benefit. The
effect of these provisions will be to eliminate the rights of the Company and
its stockholders (through stockholders' derivatives suits on behalf of the
Company) to recover monetary damages against a director for breach of fiduciary
duty as a director (including breaches resulting from grossly negligent
behavior), except in the situations described above. These provisions will not
limit the liability of directors under federal securities laws and will not
affect the availability of equitable remedies such as an injunction or
rescission based upon a director's breach of his duty of care.

DESCRIPTION OF CERTAIN INDEBTEDNESS

Senior Credit Facility

Pursuant to the Amended and Restated Loan Agreement dated as of July 10,
1998, two wholly owned subsidiaries of CCIC, CCI and Crown Castle International
Corp. de Puerto Rico ("CCIC(PR)") (collectively, the "Borrowers"), have entered
into the Senior Credit Facility with a group of banks and other financial
institutions led by Key Corporate Capital Inc. ("KeyCorp") and PNC Bank,
National Association, as arrangers and agents. The following summary of certain
provisions of the Senior Credit Facility does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the provisions of
the Senior Credit Facility.

The Senior Credit Facility provides for revolving credit loans in an
aggregate principal amount not to exceed $100.0 million, for working capital
needs, acquisitions and general corporate purposes. The Senior Credit Facility
includes a $5.0 million sublimit available for the issuance of letters of
credit. As of March 1, 1999, CCI and its subsidiaries had unused borrowing
availability under the Senior Credit Facility of $54.0 million.

The loan commitment under the Senior Credit Facility reduces by $5.0
million commencing March 31, 2001 and by $5.0 million each calendar quarter
thereafter until December 31, 2004, when the Senior Credit Facility matures. In
addition, the Senior Credit Facility provides for mandatory reduction of the
loan commitment and mandatory prepayment with the (i) net proceeds of certain
asset sales, (ii) net proceeds of certain required capital contributions to CCI
by CCIC relating to the proceeds from the sale of equity, convertible or debt
securities, subject to certain exceptions, (iii) net proceeds of any unused
insurance proceeds and (iv) a percentage of the excess cash flow of the
Borrowers, commencing with the calendar year ending December 31, 2000.

The Borrowers' obligations under the Senior Credit Facility are guaranteed
by each direct and indirect majority owned subsidiary of CCI and are also
secured by (i) a pledge by the Borrowers of all of the outstanding capital
stock of each of their respective direct subsidiaries and (ii) a perfected
first priority security interest in substantially all of the personal property
of the Borrowers and their subsidiaries. In addition, the Senior Credit
Facility is guaranteed on a limited recourse basis by CCIC, limited in recourse
to the collateral pledged by CCIC (the capital stock of CCI). The capital stock
of CTSH will not be pledged to secure the Senior Credit Facility.

The loans under the Senior Credit Facility will bear interest, at the
Borrowers' option, at either (A) a "base rate" equal to KeyCorp's prime lending
rate plus an applicable spread ranging from 0% to 1.5% (determined based on a
leverage ratio) or (B) a "LIBOR rate" plus an applicable spread ranging from
1.0% to 3.25% (determined based on a leverage ratio). Following the occurrence
and during the continuance of an event of default under the Senior Credit
Facility, the loans will bear interest at the "base rate" plus 3.5%.

The Senior Credit Facility contains a number of covenants that, among other
things, restrict the ability of the Borrowers and their respective subsidiaries
to dispose of assets, incur additional indebtedness, incur guaranty
obligations, repay subordinated indebtedness except in accordance with the
subordination provisions, pay dividends or make capital distributions, create
liens on assets, enter into leases, make investments, make acquisitions, engage
in mergers or consolidations, make capital expenditures, engage in certain
transactions with subsidiaries and affiliates and otherwise restrict corporate
activities. In addition, the Senior Credit Facility will require compliance
with certain financial covenants, including requiring the Borrowers and their
respective subsidiaries to maintain a maximum ratio of indebtedness to
operating cash flow, a minimum ratio of operating cash flow to fixed charges, a
minimum ratio of operating cash flow to projected debt service and a minimum
ratio of operating cash flow to interest expense. CCIC does not expect that
such covenants will materially impact the ability of the Borrowers and their
respective subsidiaries to operate their respective businesses.

143
<PAGE>

Pursuant to the terms of the Senior Credit Facility, CCI is entitled to pay
dividends or make distributions to CCIC in order to permit CCIC to pay its out-
of-pocket costs for corporate development and overhead and to pay cash interest
on certain indebtedness of CCIC (including the Notes); provided that the amount
of such dividends or distributions does not exceed (i) $6.0 million in any year
ending on or prior to October 31, 2002 or (ii) $33.0 million in any year
thereafter. The Senior Credit Facility also allows CCI to pay dividends or
distribute cash to CCIC to the extent required to pay taxes allocable to the
Borrowers and their respective subsidiaries. All of the above-mentioned
dividends or distributions, however, including dividends or distributions that
are intended to pay interest on the Notes, may not be made by CCI so long as
any default or event of default exists under the Senior Credit Facility.

The Senior Credit Facility contains customary events of default, including
the failure to pay principal when due or any interest or other amount that
becomes due within two days after the due date thereof, any representation or
warranty being made by the Borrowers that is incorrect in any material respect
on or as of the date made, a default in the performance of any negative
covenants or a default in the performance of certain other covenants or
agreements for a period of thirty days, default in certain other indebtedness,
certain insolvency events and certain change of control events. In addition, a
default under the Notes Indenture will result in a default under the Senior
Credit Facility.

CTI Credit Facility

Pursuant to the Loan Amendment Agreement dated May 21, 1997 (the "CTI
Credit Facility"), among CTI, as borrower, CTSH, as guarantor, Credit Suisse
First Boston, as arranger and agent ("CSFB"), and J.P. Morgan Securities Ltd.,
as co-arranger ("JPM"), CTI's (Pounds)162.5 million term and revolving loan
facilities (the "Old Facilities") were amended to a (Pounds)64.0 million
revolving loan facility. The following summary of certain provisions of the CTI
Credit Facility does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the provisions of the CTI Credit
Facility.

The CTI Credit Facility provides for revolving credit loans in an aggregate
principal amount not to exceed (Pounds)64.0 million to finance capital
expenditures in respect of digital terrestrial television with up to
(Pounds)46.5 million of such amount available for working capital needs and for
general corporate purposes. As of March 1, 1999, CTI and its subsidiaries had
unused borrowing availability under the CTI Credit Facility of approximately
(Pounds)24.0 million ($39.9 million).

The loan commitment under the CTI Credit Facility will be automatically
reduced to zero in three equal semi-annual installments commencing on May 31,
2001 and ending on May 31, 2002, when the CTI Credit Facility matures. In
addition, the CTI Credit Facility provides for mandatory cancellation of all or
part of the loan commitment and mandatory prepayment (i) with an amount equal
to the net proceeds of certain asset sales and (ii) upon the consummation of an
initial public offering or the listing on any stock exchange of the shares of
CTI, CTSH or CCIC.

CTI's and CTSH's obligations under the CTI Credit Facility are secured by
fixed and floating charges over all of their respective assets. The loans under
the CTI Credit Facility will bear interest at a "LIBOR rate" plus 0.85% and a
spread related to the lenders' cost of making the CTI Credit Facility available
to CTI.

The CTI Credit Facility contains a number of covenants that, among other
things, restrict the ability of CTI to dispose of assets, incur additional
indebtedness, incur guaranty obligations, repay subordinated indebtedness
except in accordance with the subordination provisions, pay dividends or make
capital distributions, create liens on assets, make investments, make
acquisitions, engage in certain transactions with subsidiaries and affiliates
and otherwise restrict corporate activities. In

144
<PAGE>

addition, the CTI Credit Facility will require compliance with certain
financial covenants, including requiring CTI to maintain a maximum ratio of
indebtedness to EBITDA, a minimum ratio of EBITDA to interest expense, and a
minimum tangible net worth. CCIC does not expect that such covenants will
materially impact the ability of CTI to operate its business.

The CTI Credit Facility contains customary events of default, including the
failure to pay principal or any interest or any other amount that becomes due
within three business days after the due date thereof, any representation or
warranty being made by CTI that is untrue or misleading on the date made, a
default in the performance of any of its covenants under the CTI Credit
Facility (unless, if such default is capable of remedy, such default is cured
within 14 days of CTI becoming aware of such default), default in certain other
indebtedness, certain insolvency events and certain change of control events.

On July 17, 1998, the lenders (acting through Credit Suisse First Boston,
as agent) under the CTI Credit Facility waived a provision in the CTI Credit
Facility that would have required the repayment of the CTI Credit Facility
concurrently with the listing of the Company's common stock.

The 10 5/8% Notes

On November 20, 1997, the Company privately placed $251.0 million principal
amount at maturity ($150,010,150 initial accreted value) of its 10 5/8% Senior
Discount Notes due 2007 (the "10 5/8% Notes"). The following is a summary of
certain terms of the 10 5/8% Notes and is qualified in its entirety by
reference to the indenture governing the 10 5/8% Notes (the "10 5/8%Notes
Indenture") relating to the 10 5/8% Notes. A copy of the 10 5/8 Notes Indenture
has been filed with the Registration Statement of which this prospectus forms a
part.

The 10 5/8% Notes are unsecured senior obligations of the Company, and will
rank pari passu in right of payment with all existing and future senior
indebtedness of the Company and will be senior to future subordinated
indebtedness of the Company. The 10 5/8% Notes mature on November 15, 2007. The
10 5/8% Notes will accrete in value until November 15, 2002. Thereafter, cash
interest will accrue on the 10 5/8% Notes at the rate of 10.625% per annum and
will be payable semi-annually, commencing on May 15, 2003.

Except as stated below, the 10 5/8% Notes are not redeemable prior to
November 15, 2002. Thereafter, the 10 5/8% Notes are redeemable at the option
of the Company, in whole or in part, at any time or from time to time, at a
premium which is at a fixed percentage that declines to par on or after
November 15, 2005, in each case together with accrued and unpaid interest, if
any, to the date of redemption. In the event the Company consummates a public
equity offering or certain strategic equity investments prior to November 15,
2000, the Company may, at its option, use all or a portion of the proceeds from
such offering to redeem up to 35% of the original aggregate principal amount at
maturity of the 10 5/8% Notes at a redemption price equal to 110.625% of the
accreted value of the 10 5/8% Notes to be redeemed, plus accrued and unpaid
interest, if any, thereon to the redemption date, provided at least 65% of the
original aggregate principal amount at maturity of the 10 5/8% Notes remains
outstanding after each such redemption.

Upon the occurrence of a Change of Control (as defined in the 10 5/8% Notes
Indenture), each holder of Notes has the right to require the Company to
purchase all or a portion of such holder's 10 5/8% Notes at a price equal to
101% of the aggregate principal amount thereof, together with accrued and
unpaid interest to the date of purchase.

The 10 5/8% Notes Indenture contains certain covenants, including covenants
that limit (i) indebtedness, (ii) restricted payments, (iii) distributions from
restricted subsidiaries, (iv) transactions with affiliates, (v) sales of assets
and subsidiary stock (including sale and leaseback transactions), (vi) dividend
and other payment restrictions affecting restricted subsidiaries, and (vii)
mergers or consolidations.

The CTI Bonds

On May 21, 1997, a subsidiary of CTSH issued (Pounds)125.0 million
aggregate principal amount of its 9% Guaranteed Bonds due 2007 (the "CTI
Bonds"). The CTI Bonds are listed on the Luxembourg Stock Exchange. The
following is a summary of certain terms of the Bonds and is qualified in its
entirety by reference to the trust deed dated May 21, 1997 (the "Trust Deed")
relating to the Bonds. A copy of the Trust Deed has been filed with the
Registration Statement of which this prospectus forms a part.

The CTI Bonds constitute direct, general and unconditional guaranteed
obligations of the subsidiary of CTSH and rank pari passu with all other
present and future unsecured and unsubordinated obligations of such subsidiary.
The CTI Bonds are guaranteed jointly and severally by CTI and CTSH. The CTI
Bonds will mature on March 30, 2007. Interest on the Bonds is payable annually
in arrears on March 30 in each year, the first payment having been made on
March 30, 1998.

The CTI Bonds may be redeemed at the option of the Company in whole or in
part, at any time or from time to time, at the greater of their principal and
such price as will provide a gross redemption yield 0.5% per annum above the
gross redemption yield of the benchmark gilt plus, in either case, accrued and
unpaid interest.

Upon the occurrence of a Put Event (as defined in the Trust Deed), each
holder of CTI Bonds has the right to require such subsidiary to purchase all or
a portion of such holder's CTI Bonds at a price equal to 101% of the aggregate
principal amount thereof, together with accrued and unpaid interest to the date
of purchase.

The Trust Deed contains certain covenants, including covenants that limit
(i) indebtedness, (ii) restricted payments, (iii) distributions from restricted
subsidiaries, (iv) transactions with affiliates, (v) sales of assets and
subsidiary stock, (vi) dividend and other payment restrictions affecting
restricted subsidiaries, and (vii) mergers or consolidations.

Proposed BAM JV Credit Facility

Key Corporate Capital Inc. ("KeyCorp") has committed, subject to formation
of the joint venture and certain other conditions, to provide the Proposed BAM
JV with a revolving credit facility not to exceed $250.0 million. The following
summary of certain provisions of the proposed loan facility (the "Proposed BAM
JV Credit Facility") does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the provisions of the Proposed BAM
JV Credit Facility.

The Proposed BAM JV Credit Facility provides for revolving credit loans in
an aggregate principal amount not to exceed $250.0 million, $180.0 million of
which is expected to be drawn in connection with the formation of the Proposed
BAM JV, and the balance of which will be used for acquisition and construction
of tower facilities, capital expenditures, working capital needs and general
corporate purposes. The borrowing base until September 30, 2001, is based on a
multiple of test operating cash flow. On September 30, 2001 (the "Conversion
Date"), the borrowing base test will be eliminated and the amount of the
facility will be decreased to the borrowing base as of that date. The Proposed
BAM JV Credit Facility includes a $25.0 million sublimit available for the
issuance of letters of credit.

The amount of the facility after the Conversion Date will be reduced on a
quarterly basis until March 31, 2006, when the Proposed BAM JV Credit Facility
matures. The annual percentage reduction in this loan commitment is 3.0% in
2001 (two quarters), 7.5% in 2002, 22.5% in 2003, 26.0% in 2004, 32.0% in 2005
and 9.0% in 2006 (one quarter). In addition, the Proposed BAM JV Credit
Facility provides for mandatory reduction of the loan commitment and mandatory
prepayment

146
<PAGE>

with the (1) net proceeds of certain asset sales, (2) 50% of capital
contributions to Holdco subject to certain significant exceptions including
capital expenditures pursuant to the Build-to-Suit Agreement, (3) net proceeds
of any unused insurance proceeds and (4) a percentage of the excess cash flow
of the Proposed BAM JV, commencing with the calendar year ending December 31,
2001.

The Proposed BAM JV's obligations under the Proposed BAM JV Credit Facility
are secured by (1) a pledge of the membership interest in the Proposed BAM JV
and (2) a perfected first priority security interest in the Proposed BAM JV's
interest in tenant leases including the Global Lease. The Proposed BAM JV
Credit Facility contractually permits the Proposed BAM JV to pay maintenance,
operating, ground lease and other expenses and costs relating to the tower
facilities out of the tower rentals whether or not an event of default has
occurred.

The loans under the Proposed BAM JV Credit Facility will bear interest, at
the Proposed BAM JV's option, at either (A) a "base rate" equal to KeyCorp's
prime lending rate plus an applicable spread ranging from 0% to 1.25%
(determined based on a leverage ratio) or (B) a "LIBOR rate" plus an applicable
spread ranging from 1.0% to 2.875% (determined based on a leverage ratio). The
Proposed BAM JV must hedge approximately 50% of its variable interest rate
obligations for a period of two years. Following the occurrence of and during
the continuance of an event of default under the Proposed BAM JV Credit
Facility, the loans will bear interest at the "base rate" plus 4.875%.

The Proposed BAM JV Credit Facility will contain a number of covenants
that, among other things, restrict the ability of the Proposed BAM JV to
dispose of assets, incur additional indebtedness, incur guaranty obligations,
repay subordinated indebtedness except in accordance with the subordination
provisions, pay dividends or make capital distributions, create liens on
assets, enter into leases, make investments, make acquisitions, engage in
mergers or consolidations, make capital expenditures, engage in certain
transactions with subsidiaries and affiliates and otherwise restrict company
activities. In addition, the Proposed BAM JV Credit Facility will require
compliance with certain financial covenants, including requiring the Proposed
BAM JV to maintain a minimum ratio of operating cash flow to indebtedness, a
minimum ratio of operating cash flow to fixed charges, a minimum ratio of
operating cash flow to projected debt service and a minimum ratio of operating
cash flow to interest expense. The Proposed BAM JV does not expect that such
covenants will materially impact its ability to operate its business.

The Proposed BAM JV Credit Facility contains customary events of default,
including the failure to pay principal when due or any interest or other amount
that becomes due within two days after the due date thereof, any representation
or warranty being made by the Proposed BAM JV that is incorrect in any material
respect on or as of the date made, a default in the performance of any negative
covenants or a default in the performance of certain other covenants or
agreements (including the Formation Agreement) for a period of days, default in
certain other indebtedness, certain insolvency events and certain change of
control events. During the first two years of the Proposed BAM JV Credit
Facility, capital contributions can cure an operating cash flow default and
certain other covenant and agreement defaults.

CCIC Term Loan Facility

Pursuant to a Term Loan Agreement dated as of March 15, 1999, the Company
has entered into a credit facility (the "Term Loan Facility") with a group of
banks and other financial institutions led by Goldman Sachs Credit Partners
L.P., Salomon Brothers Holding Company Inc. and Credit Suisse First Boston. As
of March 16, 1999, the Company had borrowed $100.0 million under the Term Loan
Facility to fund or refinance its escrow payments made in connection with the
Proposed Powertel Acquisition and the Proposed BellSouth Transaction. The
following summary of the Term Loan Facility does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, the provisions
of the Term Loan Facility.

147
<PAGE>

The Term Loan Facility provides for term loans in an aggregate principal
amount not to exceed $100.0 million. The loans under the Term Loan Facility
mature on November 30, 2007 and bear interest at an increasing rate based on
LIBOR as set forth in the Term Loan Agreement, but in no event shall the
interest on such loans exceed 16%. At any time the Company may, at its option,
prepay the term loans without penalty or premium. Subject to limited
exceptions, the Term Loan Facility requires the Company to prepay the loans
without penalty or premium with the proceeds of (1) any offering of debt or
equity securities, (2) the incurrence of other debt (other than debt under the
Senior Credit Facility), (3) asset sales for cash consideration, or with a fair
market value, in excess of $1.0 million, (4) any recovery of amounts deposited
in escrow in connection with the Proposed Powertel Acquisition and the Proposed
BellSouth Transaction and (5) amounts reserved for the Proposed BAM JV if the
Formation Agreement expires or is otherwise terminated.

The Term Loan Agreement contains covenants substantially identical to the
covenants contained in the Company's 10 5/8% Notes. At any time on or after
March 16, 2000, the lenders under the Term Loan Agreement may exchange their
term loans for an equal aggregate principal amount of the Company's Senior
Exchange Notes due 2007. These exchange notes will be issued pursuant to an
indenture dated as of March 15, 1999, between the Company and United States
Trust Company of New York, as trustee. These exchange notes will have the same
maturity as the term loans and will bear interest at the rate in effect with
respect to the term loans on the date of exchange. The covenants contained in
the exchange note indenture will be substantially identical to the covenants
contained in the certificate of designations governing the Company's 12 3/4%
Senior Exchangeable Preferred Stock due 2011, with additional covenants
restricting the incurrence of liens and sale-leaseback transactions.

[D] DESCRIPTION OF THE NOTES

General

You can find the definitions of certain terms used in the following summary
under the subheading "Certain Definitions." In this summary, the word "Company"
refers only to Crown Castle International Corp. and not to any of its
Subsidiaries.

The Company will issue the notes under an Indenture (the "Indenture")
between itself and United States Trust Company of New York, as trustee. The
terms of the notes include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act").

The following description is a summary of the material provisions of the
Indenture. It does not restate the Indenture in its entirety. We urge you to
read the Indenture, because it, and not this description, define your rights as
holders of the notes. A copy of the proposed form of Indenture has been filed
as an exhibit to the registration statement which includes this prospectus and
is available as set forth below under "--Additional Information."

These notes:

(1) are general obligations of the Company;

(2) are unsecured;

(3) are pari passu in right of payment with all future unsecured senior
Indebtedness of the Company.

The operations of the Company are conducted through its Subsidiaries and,
therefore, the Company depends on the cash flow of its Subsidiaries to meet its
obligations, including its obligations under the notes. The Company's
Subsidiaries will not be guarantors of the notes and the notes will be
effectively subordinated to all Indebtedness (including all borrowings under
the Senior Credit Facility, the CTI Credit Facility and the CTI Bonds) and
other liabilities and commitments (including trade payables and lease
obligations) of the Company's Subsidiaries. Any right of the Company to receive
assets of any of its Subsidiaries upon the latter's liquidation or
reorganization (and the consequent right of the holders of the notes to
participate in those assets) will be effectively subordinated to the claims of
that Subsidiary's creditors, except to the extent that the Company is itself
recognized as a creditor of such Subsidiary, in which case the claims of the
Company would still be subordinate in right of payment to any security in the
assets of such Subsidiary and any indebtedness of such Subsidiary senior to
that held by the Company. As of December 31, 1998, after giving pro forma
effect to the Proposed Transactions, the Company's Subsidiaries would have had
$441.6 million of Indebtedness outstanding, and would have had $77.6 million
and $51.2 million of unused borrowing availability, respectively, under the
Senior Credit Facility and the CTI Credit Facility. The provisions of the
Senior Credit Facility, the CTI Credit Facility and the CTI Bonds contain
substantial restrictions on the ability of such Subsidiaries to dividend or
distribute cash flow or assets to the Company. See "Risk Factors--Holding
Company Structure; Restrictions on Access to Cash Flow of Subsidiaries" and
"Description of the Senior Credit Facility."

As of the date of the Indenture, all of the Company's Subsidiaries other
than (1) CTSH and its subsidiaries and (2) Crown Castle Investment Corp. and
Crown Castle Investment Corp. II and their subsidiaries, through which the
Company intends to hold its interest in the Proposed BAM JV, will be Restricted
Subsidiaries. However, under certain circumstances, the Company will be able to
designate current or future Subsidiaries as Unrestricted Subsidiaries.
Unrestricted Subsidiaries will not be subject to many of the restrictive
covenants set forth in the Indenture.

Principal, Maturity and Interest

The notes will be limited in aggregate principal amount at maturity to $
million and will mature on , 2011. The notes are being offered at a
substantial discount from their
principal amount at maturity. See "Certain United States Federal Income Tax
Considerations--U.S. Holders--Interest and Original Issue Discount." Until
, 2004, no interest will accrue, but the Accreted Value will accrete
(representing the amortization of original issue discount) between the date of
original issuance and , 2004, on a semiannual bond equivalent basis
using a 360-day year comprised of twelve 30-day months such that the Accreted
Value shall be equal to the full principal amount of the notes on ,
2004 (the "Full Accretion Date"). The initial Accreted Value per $1,000 in
principal amount of notes will be $300.0 million (representing the original
price at which notes are being offered in the debt offering). Beginning on
, 2004, interest on the notes will accrue at the rate of % per
annum and will be payable in U.S. dollars semiannually in arrears on
and , commencing on , 2004, to holders of
record on the immediately preceding and . Holders of
record on such record dates will become irrevocably entitled to receive accrued
interest, in respect of the interest period during which such record date
occurs as of the close of business on such record date. Interest on the notes
will accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Full Accretion Date. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months. Principal,
premium, if any, and interest on the notes will be payable at the office or
agency of the Company maintained for such purpose within the City and State of
New York or, at the option of the Company, payment of interest may be made by
check mailed to the holders of the notes at their respective addresses set
forth in the register of holders of notes; provided that all payments of
principal, premium and interest with respect to notes the holders of which have
given wire transfer instructions to the Company will be required to be made by
wire transfer of immediately available funds to the accounts in the United
States specified by those holders. Until otherwise designated by the Company,
the Company's office or agency in New York will be the office of the trustee
maintained for such purpose. The notes will be issued in denominations of
$1,000 and integral multiples thereof.

Optional Redemption

Except as described below, the notes will not be redeemable at the
Company's option prior to , 2004. Thereafter, the notes will be
subject to redemption at any time at the option of the Company, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest thereon, if any, to the applicable redemption date
(subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date), if redeemed during
the twelve-month period beginning on of the years indicated below:

Year Percentage
---- ----------
2004........................................ %
2005........................................ %
2006........................................ %
2007 and thereafter......................... 100.000%

During the first 36 months after the date of original issuance of the
notes, the Company may on any one or more occasions redeem up to 35% of the
aggregate principal amount at maturity of notes originally issued at a
redemption price of % of the Accreted Value thereof on the redemption date
with the net cash proceeds of one or more Public Equity Offerings and/or
Strategic Equity Investments; provided that at least 65% of the aggregate
principal amount at maturity of notes originally issued remains outstanding
immediately after the occurrence of such redemption (excluding

150
<PAGE>

notes held by the Company or any of its Subsidiaries); and provided, further,
that such redemption shall occur within 60 days of the date of the closing of
such Public Equity Offering and/or Strategic Equity Investment.

Selection and Notice

If less than all of the notes are to be redeemed at any time, selection of
notes for redemption will be made by the trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the notes are listed, or, if the notes are not so listed, on a pro rata basis,
by lot or by such method as the trustee shall deem fair and appropriate;
provided that no notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each holder of notes to be redeemed at its
registered address. Notices of redemption may not be conditional. If any note
is to be redeemed in part only, the notice of redemption that relates to such
note shall state the portion of the principal amount thereof to be redeemed. A
new note in principal amount equal to the unredeemed portion thereof will be
issued in the name of the holder thereof upon cancellation of the original
note. notes called for redemption become due on the date fixed for redemption.
On and after the redemption date, interest ceases to accrue on notes or
portions of them called for redemption.

Mandatory Redemption

The Company is not required to make mandatory redemption or sinking fund
payments with respect to the notes.

Repurchase at the Option of Holders

Change of Control

If a Change of Control occurs, each holder of notes will have the right to
require the Company to repurchase all or any part (equal to $1,000 or an
integral multiple thereof) of such holder's notes pursuant to the offer
described below (the "Change of Control Offer") at an offer price in cash equal
to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest thereon, if any (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date), to the date of purchase or, in the case of repurchases of notes prior to
the Full Accretion Date, at a purchase price equal to 101% of the Accreted
Value thereof on the date of repurchase, to such date of repurchase (the
"Change of Control Payment"). Within 30 days following any Change of Control,
the Company will mail a notice to each holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
notes on the date specified in such notice, which date shall be no earlier than
30 days and no later than 60 days from the date such notice is mailed (the
"Change of Control Payment Date"), pursuant to the procedures required by the
Indenture and described in such notice.

On the Change of Control Payment Date, the Company will, to the extent
lawful:

(1) accept for payment all notes or portions thereof properly tendered
pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of
Control Payment in respect of all notes or portions thereof so tendered;
and

(3) deliver or cause to be delivered to the trustee the notes so accepted
together with an Officers' Certificate stating the aggregate principal
amount of notes or portions thereof being purchased by the Company.

151
<PAGE>

The paying agent will promptly mail to each holder of notes so tendered the
Change of Control Payment for such notes, and the trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each holder
a new note equal in principal amount to any unpurchased portion of the notes
surrendered, if any; provided that each such new note will be in a principal
amount of $1,000 or an integral multiple thereof.

The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. The Company will
comply, to the extent applicable, with the requirements of Section 14(e) of the
Exchange Act and any other securities laws or regulations applicable to any
Change of Control Offer. To the extent that the provisions of any such
securities laws or securities regulations conflict with the provisions of the
covenant described above, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the covenant described above by virtue thereof.

The Change of Control purchase feature is a result of negotiations between
the Company and the Initial Purchasers. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company would decide to do so in the future. Subject to the
limitations discussed below, the Company could, in the future, enter into
certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
Indenture, but that could increase the amount of Indebtedness outstanding at
such time or otherwise affect the Company's capital structure. Restrictions on
the ability of the Company to incur additional Indebtedness are contained in
the covenants described under "--Certain Covenants--Incurrence of Indebtedness
and Issuance of Preferred Stock," "--Certain Covenants--Liens" and "--Certain
Covenants--Sale and Leaseback Transactions." Such restrictions can only be
waived with the consent of the holders of a majority in principal amount of the
notes then outstanding. Except for the limitations contained in such covenants,
however, the Indenture will not contain any covenants or provisions that may
afford holders of the notes protection in the event of certain highly leveraged
transactions.

The Senior Credit Facility limits the Company's access to the cash flow of
its Subsidiaries and will, therefore, restrict the Company's ability to
purchase any notes. The Senior Credit Facility also provides that the
occurrence of certain change of control events with respect to the Company
constitute a default thereunder. In the event that a Change of Control occurs
at a time when the Company's Subsidiaries are prohibited from making
distributions to the Company to purchase notes, the Company could cause its
Subsidiaries to seek the consent of the lenders under the Senior Credit
Facility to allow such distributions or could attempt to refinance the
borrowings that contain such prohibition. If the Company does not obtain such a
consent or repay such borrowings, the Company will remain prohibited from
purchasing notes. In such case, the Company's failure to purchase tendered
notes would constitute an Event of Default under the Indenture which would, in
turn, constitute a default under the Senior Credit Facility. Future
indebtedness of the Company and its Subsidiaries may contain prohibitions on
the occurrence of certain events that would constitute a Change of Control or
require such indebtedness to be repurchased upon a Change of Control. Moreover,
the exercise by the holders of their right to require the Company to repurchase
the notes could cause a default under such indebtedness, even if the Change of
Control itself does not, due to the financial effect of such repurchase on the
Company. Finally, the Company's ability to pay cash to the holders of notes
following the occurrence of a Change of Control may be limited by the Company's
then existing financial resources, including its ability to access the cash
flow of its Subsidiaries. See "Risk Factors--Repurchase of the notes Upon a
Change of Control" and "Risk Factors--Holding Company Structure; Restrictions
on Access to Cash Flow of Subsidiaries." There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases.

152
<PAGE>

The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set
forth in the Indenture applicable to a Change of Control Offer made by the
Company and purchases all notes validly tendered and not withdrawn under such
Change of Control Offer. The provisions under the Indenture relative to the
Company's obligation to make an offer to repurchase the notes as a result of a
Change of Control may be waived or modified with the written consent of the
holders of a majority in principal amount of the notes then outstanding.

The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Restricted Subsidiaries taken as a whole.
Although there is a developing body of case law interpreting the phrase
"substantially all," there is no precise established definition of the phrase
under applicable law. Accordingly, the ability of a holder of notes to require
the Company to repurchase such notes as a result of a sale, lease, transfer,
conveyance or other disposition of less than all of the assets of the Company
and its Subsidiaries taken as a whole to another Person or group may be
uncertain.

Asset Sales

The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be)
receives consideration at the time of such Asset Sale at least equal to the
fair market value (evidenced by a resolution of the Board of Directors set
forth in an Officers' Certificate delivered to the trustee) of the assets
or Equity Interests issued or sold or otherwise disposed of; and

(2) except in the case of a Tower Asset Exchange, at least 75% of the
consideration therefor received by the Company or such Restricted
Subsidiary is in the form of cash or Cash Equivalents; provided that the
amount of:

(a) any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet), of the Company or any
Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the notes or any
guarantee thereof) that are assumed by the transferee of any such
assets pursuant to a customary novation agreement that releases the
Company or such Restricted Subsidiary from further liability; and

(b) any securities, notes or other obligations received by the
Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash within
20 days of the applicable Asset Sale (to the extent of the cash
received), shall be deemed to be cash for purposes of this provision.

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the
Company or the applicable Restricted Subsidiary may apply such Net Proceeds to:

(1) reduce Indebtedness under a Credit Facility;

(2) reduce other Indebtedness of any of the Company's Restricted
Subsidiaries;

(3) the acquisition of all or substantially all the assets of a Permitted
Business;

(4) the acquisition of Voting Stock of a Permitted Business from a Person
that is not a Subsidiary of the Company; provided, that, after giving
effect thereto, the Company or its Restricted Subsidiary owns a majority of
such Voting Stock; or

153
<PAGE>

(5) the making of a capital expenditure or the acquisition of other long-
term assets that are used or useful in a Permitted Business.

Pending the final application of any such Net Proceeds, the Company may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph will be deemed to constitute "Excess
Proceeds." When the aggregate amount of Excess Proceeds exceeds $5.0 million,
the Company will be required to make an offer to all holders of notes and all
holders of other senior Indebtedness of the Company containing provisions
similar to those set forth in the Indenture with respect to offers to purchase
or redeem with the proceeds of sales of assets (an "Asset Sale Offer") to
purchase the maximum principal amount (or accreted value, as applicable) of
notes and such other senior Indebtedness of the Company that may be purchased
out of the Excess Proceeds. The offer price for the notes will be payable in
cash and will be 100% of the principal amount of any notes purchased after the
Full Accretion Date, plus accrued interest to the date of purchase, and 100% of
the Accreted Value of any notes purchased prior to the Full Accretion Date. In
the case of any such other senior Indebtedness, the offer price will be 100% of
the principal amount (or accreted value, as applicable) thereof plus accrued
and unpaid interest thereon, if any, to the date of purchase. Each Asset Sale
Offer will be made in accordance with the procedures set forth in the Indenture
and such other senior Indebtedness of the Company. To the extent that any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company
may use such Excess Proceeds for any purpose not otherwise prohibited by the
Indenture. If the aggregate principal amount of notes and such other senior
Indebtedness of the Company tendered into such Asset Sale Offer surrendered by
holders thereof exceeds the amount of Excess Proceeds, the trustee shall select
the notes and such other senior Indebtedness to be purchased on a pro rata
basis. Upon completion of such offer to purchase, the amount of Excess Proceeds
shall be reset at zero.

Certain Covenants

Restricted Payments

The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution
on account of the Company's or any of its Restricted Subsidiaries' Equity
Interests (including, without limitation, any payment in connection with
any merger or consolidation involving the Company or any of its Restricted
Subsidiaries) or to the direct or indirect holders of the Company's or any
of its
Restricted Subsidiaries' Equity Interests in their capacity as such (other
than dividends or distributions payable in Equity Interests (other than
Disqualified Stock) of the Company or to the Company or a Restricted
Subsidiary of the Company);

(2) purchase, redeem or otherwise acquire or retire for value (including
without limitation, in connection with any merger or consolidation
involving the Company) any Equity Interests of the Company or any direct or
indirect parent of the Company (other than any such Equity Interests owned
by the Company or any Restricted Subsidiary of the Company);

(3) make any payment on or with respect to, or purchase, redeem, defease
or otherwise acquire or retire for value any Indebtedness that is
subordinated to the notes, except a payment of interest or principal at
Stated Maturity; or

(4) make any Restricted Investment, (all such payments and other actions
set forth in clauses (1) through (4) above being collectively referred to
as "Restricted Payments"),

154
<PAGE>

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default shall have occurred and be continuing or would occur as a
consequence thereof; and

(2) the Company would have been permitted to incur at least $1.00 of
additional Indebtedness pursuant to the Debt to Adjusted Consolidated Cash
Flow Ratio test set forth in the first paragraph of the covenant described
below under the caption "--Incurrence of Indebtedness and Issuance of
Preferred Stock"; provided that the Company and its Restricted Subsidiaries
will not be required to comply with this clause (2) in order to make any
Restricted Investment; and

(3) such Restricted Payment, together with the aggregate amount of all
other Restricted Payments made by the Company and its Restricted
Subsidiaries after the date of the Indenture (excluding Restricted Payments
permitted by clauses (2), (3) and (4) of the next succeeding paragraph), is
less than the sum, without duplication, of:

(a) 50% of the Consolidated Net Income of the Company for the period
(taken as one accounting period) from the beginning of the first fiscal
quarter commencing after the date of the Indenture to the end of the
Company's most recently ended fiscal quarter for which internal
financial statements are available at the time of such Restricted
Payment (or, if such Consolidated Net Income for such period is a
deficit, less 100% of such deficit); plus

(b) 100% of the aggregate net cash proceeds received by the Company
since the IPO Date as a contribution to its common equity capital or
from the issue or sale of Equity Interests of the Company (other than
Disqualified Stock and except to the extent such net cash proceeds are
used to incur new Indebtedness outstanding pursuant to clause (11) of
the second paragraph of the covenant described below under the caption
"Incurrence of Indebtedness and Issuance of Preferred Stock") or from
the issue or sale of Disqualified Stock or debt securities of the
Company that have been converted into such Equity Interests (other than
Equity Interests (or Disqualified Stock or convertible debt securities)
sold to a Subsidiary of the Company and other than Disqualified Stock
or convertible debt securities that have been converted into
Disqualified Stock); plus

(c) to the extent that any Restricted Investment that was made after
the date of the Indenture is sold for cash or otherwise liquidated or
repaid for cash, the lesser of (A) the cash return of capital with
respect to such Restricted Investment (less the cost of disposition, if
any) and (B) the initial amount of such Restricted Investment; plus

(d) to the extent that any Unrestricted Subsidiary of the Company and
all of its Subsidiaries are designated as Restricted Subsidiaries after
the date of the Indenture, the
lesser of (A) the fair market value of the Company's Investments in
such Subsidiaries as of the date of such designation, or (B) the sum of
(x) the fair market value of the Company's Investments in such
Subsidiaries as of the date on which such Subsidiaries were originally
designated as Unrestricted Subsidiaries and (y) the amount of any
Investments made in such Subsidiaries subsequent to such designation
(and treated as Restricted Payments) by the Company or any Restricted
Subsidiary; provided that:

(i) in the event the Unrestricted Subsidiaries designated as
Restricted Subsidiaries are CTSH and its Subsidiaries, the
references in clauses (A) and (B) of this clause (d) to fair market
value of the Company's Investments in such Subsidiaries shall mean
the amount by which the fair market value of all such Investments
exceeds 34.3% of the fair market value of CTSH and its Subsidiaries
as a whole; and

(ii) in the event the Unrestricted Subsidiaries designated as
Restricted Subsidiaries are CCAIC and its Subsidiaries, the
references in clauses (A) and (B) of this clause (d)

155
<PAGE>

to fair market value of the Company's Investments in such
Subsidiaries shall mean the amount by which the fair market value of
all such Investments exceeds $250.0 million; plus

(e) 50% of any dividends received by the Company or a Restricted
Subsidiary after the date of the Indenture from an Unrestricted
Subsidiary of the Company, to the extent that such dividends were not
otherwise included in Consolidated Net Income of the Company for such
period.

The foregoing provisions will not prohibit:

(1) the payment of any dividend within 60 days after the date of
declaration thereof, if at said date of declaration such payment would have
complied with the provisions of the Indenture;

(2) the making of any Investment or the redemption, repurchase,
retirement, defeasance or other acquisition of any subordinated
Indebtedness or Equity Interests of the Company in exchange for, or out of
the net cash proceeds from the sale since the IPO Date (other than to a
Subsidiary of the Company) of, any Equity Interests of the Company (other
than any Disqualified Stock); provided that such net cash proceeds are not
used to incur new Indebtedness pursuant to clause (11) of the second
paragraph of the covenant described below under the caption "-- Incurrence
of Indebtedness and Issuance of Preferred Stock"); and provided further
that, in each such case, the amount of any such net cash proceeds that are
so utilized shall be excluded from clause (3)(b) of the preceding
paragraph;

(3) the defeasance, redemption, repurchase or other acquisition of
subordinated Indebtedness with the net cash proceeds form an incurrence of
Permitted Refinancing Indebtedness;

(4) the payment of any dividend by a Restricted Subsidiary of the Company
to the holders of its Equity Interests on a pro rata basis; or

(5) the repurchase, redemption or other acquisition or retirement for
value of any Equity Interests of the Company or any Restricted Subsidiary
of the Company held by any member of the Company's (or any of its
Restricted Subsidiaries') management pursuant to any management equity
subscription agreement or stock option agreement in effect as of the date
of the Indenture; provided that the aggregate price paid for all such
repurchased, redeemed, acquired or retired Equity Interests shall not
exceed (a) $500,000 in any twelve-month period and (b) $5.0 million in the
aggregate.

The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash)
in the Subsidiary so designated will be deemed to be Restricted Payments
at the time of such designation and will reduce the amount available for
Restricted Payments under the first paragraph of this covenant. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the fair market value of such Investments at the time of such
designation. Such designation will only be permitted if such Restricted Payment
would be permitted at such time and if such Restricted Subsidiary otherwise
meets the definition of an Unrestricted Subsidiary. The Board of Directors may
designate any Unrestricted Subsidiary to be a Restricted Subsidiary if such
designation would not cause a Default.

The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or the
applicable Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment. The fair market value of any property, assets or
Investments required by this covenant to

156
<PAGE>

be determined shall be determined by the Board of Directors whose resolution
with respect thereto shall be delivered to the trustee.

Incurrence of Indebtedness and Issuance of Preferred Stock

The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "incur") any Indebtedness (including Acquired Debt)
and that the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock;
provided that the Company may incur Indebtedness (including Acquired Debt) or
issue shares of Disqualified Stock and the Company's Restricted Subsidiaries
may incur Indebtedness if, in each case, the Company's Debt to Adjusted
Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or
the issuance of such Disqualified Stock, after giving pro forma effect to such
incurrence or issuance as of such date and to the use of proceeds therefrom as
if the same had occurred at the beginning of the most recently ended four full
fiscal quarter period of the Company for which internal financial statements
are available, would have been no greater than 7.5 to 1.

The provisions of the first paragraph of this covenant will not apply to the
incurrence of any of the following items of Indebtedness or to the issuance of
any of the following items of Disqualified Stock or preferred stock
(collectively, "Permitted Debt"):

(1) the incurrence by the Company or any of its Restricted Subsidiaries
of Indebtedness (including Indebtedness under Credit Facilities) in an
aggregate principal amount (with letters of credit being deemed to have a
principal amount equal to the maximum potential liability of the Company
and its Restricted Subsidiaries thereunder) at any one time outstanding not
to exceed the greater of (x) $200.0 million less the aggregate amount of
all Net Proceeds of Asset Sales applied to repay Indebtedness under a
Credit Facility pursuant to the covenant described above under the caption
"--Repurchase at the Option of Holders--Asset Sales" and (y) 70% of the
Eligible Receivables that are outstanding as of such date of incurrence;

(2) the incurrence by the Company and its Restricted Subsidiaries of the
Existing Indebtedness;

(3) the incurrence by the Company of the Indebtedness represented by the
notes;

(4) the incurrence by the Company of Indebtedness represented by the 12%
Senior Subordinated Exchange Debentures due 2011;

(5) the incurrence by the Company or any of its Restricted Subsidiaries
of Indebtedness represented by Capital Lease Obligations, mortgage
financings or purchase money obligations, in each case incurred for the
purpose of financing all or any part of the purchase price or cost of
construction or improvement of property, plant or equipment used in the
business of the
Company or such Restricted Subsidiary, in an aggregate principal amount,
including all Permitted Refinancing Indebtedness incurred to refund,
refinance or replace any other Indebtedness incurred pursuant to this
clause (5), not to exceed $10.0 million at any one time outstanding;

(6) the incurrence by the Company or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness in exchange for, or the net proceeds
of which are used to extend, refinance, renew, replace, defease or refund
Indebtedness of the Company or any of its Restricted Subsidiaries or
Disqualified Stock of the Company (other than intercompany Indebtedness)
that was permitted by the Indenture to be incurred under the first
paragraph hereof or clauses (2), (3), (4), (5) or this clause (6) of this
paragraph;

157
<PAGE>

(7) the incurrence by the Company or any of its Restricted Subsidiaries
of intercompany Indebtedness between or among the Company and any of its
Restricted Subsidiaries; provided, however, that (i) if the Company is the
obligor on such Indebtedness, such Indebtedness is expressly subordinated
to the prior payment in full in cash of all Obligations with respect to the
notes and that (A) any subsequent issuance or transfer of Equity Interests
that results in any such Indebtedness being held by a Person other than the
Company or a Restricted Subsidiary and (B) any sale or other transfer of
any such Indebtedness to a Person that is not either the Company or a
Restricted Subsidiary shall be deemed, in each case, to constitute an
incurrence of such Indebtedness by the Company or such Restricted
Subsidiary, as the case may be;

(8) the incurrence by the Company or any of its Restricted Subsidiaries
of Hedging Obligations that are incurred for the purpose of fixing or
hedging interest rate risk with respect to any floating rate Indebtedness
that is permitted by the terms of the Indenture to be outstanding or
currency exchange risk;

(9) the guarantee by the Company or any of its Restricted Subsidiaries of
Indebtedness of the Company or a Restricted Subsidiary of the Company that
was permitted to be incurred by another provision of the Indenture;

(10) the incurrence by the Company or any of its Restricted Subsidiaries
of Acquired Debt in connection with the acquisition of assets or a new
Subsidiary and the incurrence by the Company's Restricted Subsidiaries of
Indebtedness as a result of the designation of an Unrestricted Subsidiary
as a Restricted Subsidiary; provided that, in the case of any such
incurrence of Acquired Debt, such Acquired Debt was incurred by the prior
owner of such assets or such Restricted Subsidiary prior to such
acquisition by the Company or one of its Restricted Subsidiaries and was
not incurred in connection with, or in contemplation of, such acquisition
by the Company or one of its Restricted Subsidiaries; and provided further
that, in the case of any incurrence pursuant to this clause (10), as a
result of such acquisition by the Company or one of its Restricted
Subsidiaries, the Company's Debt to Adjusted Consolidated Cash Flow Ratio
at the time of incurrence of such Acquired Debt, after giving pro forma
effect to such incurrence as if the same had occurred at the beginning of
the most recently ended four full fiscal quarter period of the Company for
which internal financial statements are available, would have been less
than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the
same period without giving pro forma effect to such incurrence;

(11) the incurrence by the Company of Indebtedness not to exceed, at any
one time outstanding, the sum of (i) 2.0 times the aggregate net cash
proceeds plus (ii) 1.0 times the fair market value of non-cash proceeds
(evidenced by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the trustee), in each case, from the
issuance and sale, other than to a Subsidiary, of Equity Interests (other
than Disqualified Stock) of the Company since the IPO Date (less the amount
of such proceeds used to make Restricted Payments as provided in clause
(c)(ii) of the first paragraph or clause (2) of the second paragraph of the
covenant described above under the caption "--Restricted Payments");
provided that such Indebtedness does not mature prior to the Stated
Maturity of the notes and the Weighted Average Life to Maturity of such
Indebtedness is longer than that of the notes; and

(12) the incurrence by the Company or any of its Restricted Subsidiaries
of additional Indebtedness and/or the issuance by the Company of
Disqualified Stock in an aggregate principal amount, accreted value or
liquidation preference, as applicable, at any time outstanding, not to
exceed an amount equal to $100.0 million less the aggregate amount of all
Investments made pursuant to clause (12) of the definition of Permitted
Investments; provided that, notwithstanding the foregoing, the aggregate
principal amount, accreted value or liquidation preference, as applicable,
permitted to be incurred or issued pursuant to this clause (12) shall not
be reduced to less than $25.0 million.

158
<PAGE>

The Indenture will also provide that (i) the Company will not incur any
Indebtedness that is contractually subordinated in right of payment to any
other Indebtedness of the Company unless such Indebtedness is also
contractually subordinated in right of payment to the notes on substantially
identical terms; provided, however, that no Indebtedness of the Company shall
be deemed to be contractually subordinated in right of payment to any other
Indebtedness of the Company solely by virtue of being unsecured and (ii) the
Company will not permit any of its Unrestricted Subsidiaries to incur any
Indebtedness other than Non-Recourse Debt.

For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (1) through (12) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify (or later reclassify in whole
or in part) such item of Indebtedness in any manner that complies with this
covenant. Accrual of interest, accretion or amortization of original issue
discount and the payment of interest in the form of additional Indebtedness
will not be deemed to be an incurrence of Indebtedness for purposes of this
covenant. Indebtedness under Credit Facilities outstanding on the date of the
Indenture shall be deemed to have been incurred on such date in reliance on the
exception provided by clause (1) of the definition of Permitted Debt.

Liens

The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien securing Indebtedness or trade payables on any asset now owned
or hereafter acquired, or any income or profits therefrom or assign or convey
any right to receive income therefrom, except Permitted Liens.

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to:

(1) pay dividends or make any other distributions to the Company or any
of its Restricted Subsidiaries on its Capital Stock or with respect to any
other interest or participation in, or measured by, its profits;

(2) pay any indebtedness owed to the Company or any of its Restricted
Subsidiaries;

(3) make loans or advances to the Company or any of its Restricted
Subsidiaries; or

(4) transfer any of its properties or assets to the Company or any of its
Restricted Subsidiaries.

However, the foregoing restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

(1) Existing Indebtedness or Indebtedness under the Senior Credit
Facility, in each case as in effect on the date of the Indenture, and any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings thereof; provided that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings are no more restrictive, taken as
a whole, with respect to such dividend and other payment restrictions than
those contained in the applicable series of Existing Indebtedness or in the
Senior Credit Facility, in each case as in effect on the date of the
Indenture;

159
<PAGE>

(2) encumbrances and restrictions applicable to any Unrestricted
Subsidiary, as the same are in effect as of the date on which such
Subsidiary becomes a Restricted Subsidiary, and as the same may be amended,
modified, restated, renewed, increased, supplemented, refunded, replaced or
refinanced; provided that such amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacement or refinancings
are no more restrictive, taken as a whole, with respect to such dividend
and other payment restrictions than those contained in the applicable
series of Indebtedness of such Subsidiary as in effect on the date on which
such Subsidiary becomes a Restricted Subsidiary;

(3) any Indebtedness (incurred in compliance with the covenant under the
heading "--Incurrence of Indebtedness and Issuance of Preferred Stock") or
any agreement pursuant to which such Indebtedness is issued if the
encumbrance or restriction applies only in the event of a payment default
or default with respect to a financial covenant contained in such
Indebtedness or agreement and such encumbrance or restriction is not
materially more disadvantageous to the holders of the notes than is
customary in comparable financings (as determined by the Company) and the
Company determines that any such encumbrance or restriction will not
materially affect the Company's ability to pay interest or principal on the
notes;

(4) the Indenture;

(5) applicable law;

(6) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect
at the time of such acquisition (except to the extent such Indebtedness was
incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the
properties or assets of any Person, other than the Person, or the property
or assets of the Person, so acquired, provided that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of the Indenture
to be incurred;

(7) by reason of customary non-assignment provisions in leases or
licenses entered into in the ordinary course of business;

(8) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in
clause (4) in the prior paragraph on the property so acquired;

(9) the provisions of agreements governing Indebtedness incurred pursuant
to clause (4) of the second paragraph of the covenant described above under
the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock";

(10) any agreement for the sale of a Restricted Subsidiary that restricts
that Restricted Subsidiary pending its sale;

(11) Permitted Refinancing Indebtedness, provided that the restrictions
contained in the agreements governing such Permitted Refinancing
Indebtedness are no more restrictive, taken as a whole, than those
contained in the agreements governing the Indebtedness being refinanced;

(12) Liens permitted to be incurred pursuant to the provisions of the
covenant described under the caption "Liens" that limit the right of the
debtor to transfer the assets subject to such Liens;

(13) provisions with respect to the disposition or distribution of assets
or property in joint venture agreements and other similar agreements; and

(14) restrictions on cash or other deposits or net worth imposed by
customers under contracts entered into in the ordinary course of business.

Merger, Consolidation or Sale of Assets

The Company may not consolidate or merge with or into (whether or not the
Company is the surviving corporation), or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets in
one or more related transactions, to another corporation, Person or entity
unless:

(1) the Company is the surviving corporation or the entity or the Person
formed by or surviving any such consolidation or merger (if other than the
Company) or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made is a corporation organized or
existing under the laws of the United States, any state thereof or the
District of Columbia;

(2) the entity or Person formed by or surviving any such consolidation or
merger (if other than the Company) or the entity or Person to which such
sale, assignment, transfer, lease, conveyance or other disposition shall
have been made assumes all the obligations of the Company under the notes
and the Indenture pursuant to a supplemental indenture in a form reasonably
satisfactory to the trustee;

(3) immediately after such transaction no Default exists; and

(4) except in the case of a merger of the Company with or into a Wholly
Owned Restricted Subsidiary of the Company and except in the case of a
merger entered into solely for the purpose of reincorporating the Company
in another jurisdiction, the Company or the entity or Person formed by or
surviving any such consolidation or merger (if other than the Company), or
to which such sale, assignment, transfer, lease, conveyance or other
disposition shall have been made will, at the time of such transaction and
after giving pro forma effect thereto as if such transaction had occurred
at the beginning of the applicable four-quarter period, be permitted to
incur at least $1.00 of additional Indebtedness pursuant to the Debt to
Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph
of the covenant described above under the caption "--Incurrence of
Indebtedness and Issuance of Preferred Stock."

Transactions with Affiliates

The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless:

(1) such Affiliate Transaction is on terms that are no less favorable to
the Company or the relevant Restricted Subsidiary than those that would
have been obtained in a comparable transaction by the Company or such
Restricted Subsidiary with an unrelated Person; and

(2) the Company delivers to the trustee:

(a) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of
$1.0 million, a resolution of the Board of Directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction
complies with clause (1) above and that such Affiliate Transaction has
been approved by a majority of the disinterested members of the Board
of Directors; and

(b) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of
$10.0 million, an opinion as to the fairness to the holders of such
Affiliate Transaction from a financial point of view issued by an
accounting, appraisal or investment banking firm of national standing.

161
<PAGE>

Notwithstanding the foregoing, the following items shall not be deemed to
be Affiliate Transactions:

(1) any employment arrangements with any executive officer of the Company
or a Restricted Subsidiary that is entered into by the Company or any of
its Restricted Subsidiaries in the ordinary course of business and
consistent with compensation arrangements of similarly situated executive
officers at comparable companies engaged in Permitted Businesses;

(2) transactions between or among the Company and/or its Restricted
Subsidiaries;

Crown Transition Agreements, as the same are in effect on the date of the
Indenture.

Sale and Leaseback Transactions

The Company will not, and will not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company or any of its Restricted Subsidiaries may enter into a sale and
leaseback transaction if:

(1) the Company or such Restricted Subsidiary, as applicable, could have:

(a) incurred Indebtedness in an amount equal to the Attributable Debt
relating to such sale and leaseback transaction pursuant to the Debt to
Adjusted Consolidated Cash Flow Ratio test set forth in the first
paragraph of the covenant described above under the caption "--
Incurrence of Indebtedness and Issuance of Preferred Stock";

(b) incurred a Lien to secure such Indebtedness pursuant to the
covenant described above under the caption "--Liens";

(2) the gross cash proceeds of such sale and leaseback transaction are

permitted by, and the Company applies the proceeds of such transaction in
compliance with, the covenant described above under the caption "--
Repurchase at the Option of Holders--Asset Sales."

Limitation on Issuances and Sales of Capital Stock of Restricted Subsidiaries

The Company:

(1) will not, and will not permit any Restricted Subsidiary of the
Company to, transfer, convey, sell, lease or otherwise dispose of any
Equity Interests in any Restricted Subsidiary of the Company to any Person
(other than the Company or a Wholly Owned Restricted Subsidiary of the
Company); and

(2) will not permit any Restricted Subsidiary of the Company to issue
any of its Equity Interests (other than, if necessary, shares of its
Capital Stock constituting directors' qualifying

162
<PAGE>

shares) to any Person other than to the Company or a Wholly Owned
Restricted Subsidiary of the Company, unless, in each such case:

(a) as a result of such transfer, conveyance, sale, lease or other
disposition or issuance such Restricted Subsidiary no longer
constitutes a Subsidiary; and

(b) the cash Net Proceeds from such transfer, conveyance, sale,
lease or other disposition or issuance are applied in accordance with
the covenant described above under the caption "--Repurchase at the
Option of Holders--Asset Sales."

Limitations on Issuances of Guarantees of Indebtedness

The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee or pledge any assets to secure the payment of any
other Indebtedness of the Company unless such Subsidiary simultaneously
executes and delivers a supplemental indenture to the Indenture providing for
the Guarantee of the payment of the notes by such Subsidiary, which Guarantee
shall be senior to or pari passu with such Subsidiary's Guarantee of or pledge
to secure such other Indebtedness. Notwithstanding the foregoing, any such
Guarantee by a Subsidiary of the notes shall provide by its terms that it shall
be automatically and unconditionally released and discharged upon any sale,
exchange or transfer, to any Person other than a Subsidiary of the Company, of
all of the Company's stock in, or all or substantially all the assets of, such
Subsidiary, which sale, exchange or transfer is made in compliance with the
applicable provisions of the Indenture. The form of such Guarantee will be
attached as an exhibit to the Indenture.

Business Activities

The Company will not, and will not permit any Subsidiary to, engage in any
business other than Permitted Businesses, except to such extent as would not be
material to the Company and its Subsidiaries taken as a whole.

Reports

Whether or not required by the rules and regulations of the Securities and
Exchange Commission (the "Commission"), so long as any notes are outstanding,
the Company will furnish to the holders of notes:

(1) all quarterly and annual financial information that would be
required to be contained in a filing with the Commission on Forms 10-Q and
10-K if the Company were required to file such Forms, including a
"Management's Discussion and Analysis of Financial Condition and Results
of Operations" that describes the financial condition and results of
operations of the Company and its consolidated Subsidiaries (showing in
reasonable detail, in the footnotes to the financial statements and in
"Management's Discussion and Analysis of Financial Condition and Results
of Operations" (in each case to the extent not prohibited by the
Commission's rules and regulations);

(a) the financial condition and results of operations of the Company
and its Restricted Subsidiaries separate from the financial condition
and results of operations of the Unrestricted Subsidiaries of the
Company; and

(b) the Tower Cash Flow for the most recently completed fiscal
quarter and the Adjusted Consolidated Cash Flow for the most recently
completed four-quarter period) and, with respect to the annual
information only, a report thereon by the Company's certified
independent accountants; and

163
<PAGE>

(2) all current reports that would be required to be filed with the
Commission on Form 8-K if the Company were required to file such reports,
in each case within the time periods specified in the Commission's rules
and regulations.

In addition, whether or not required by the rules and regulations of the
Commission, the Company will file a copy of all such information and reports
with the Commission for public availability within the time periods specified
in the Commission's rules and regulations (unless the Commission will not
accept such a filing) and make such information available to securities
analysts and prospective investors upon request.

Events of Default and Remedies

Each of the following constitutes an Event of Default:

(1) default for 30 days in the payment when due of interest on the
notes;

(2) default in payment when due of the principal of or premium, if any,
on the notes;

(3) failure by the Company or any of its Subsidiaries to comply with the
provisions described under the caption "--Certain Covenants--Merger,
Consolidation or Sale of Assets" or failure by the Company to consummate a
Change of Control Offer or Asset Sale Offer in accordance with the
provisions of the Indenture applicable thereto;

(4) failure by the Company or any of its Subsidiaries for 30 days after
notice to comply with any of its other agreements in the Indenture or the
notes;

(5) default under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Company or any of its Significant
Subsidiaries (or the payment of which is guaranteed by the Company or any
of its Significant Subsidiaries) whether such Indebtedness or guarantee
now exists, or is created after the date of the Indenture, which default:

(a) is caused by a failure to pay principal of or premium, if any,
or interest on such Indebtedness prior to the expiration of the grace
period provided in such Indebtedness on the date of such default (a
"Payment Default"); or

(b) results in the acceleration of such Indebtedness prior to its
express maturity and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment Default or the
maturity of which has been so accelerated, aggregates $20.0 million or
more;

(6) failure by the Company or any of its Significant Subsidiaries to pay
final judgments aggregating in excess of $20.0 million, which judgments
are not paid, discharged or stayed for a period of 60 days; or

(7) certain events of bankruptcy or insolvency with respect to the
Company or any of its Restricted Subsidiaries.

If any Event of Default occurs and is continuing, the trustee or the
holders of at least 25% in principal amount at maturity of the then outstanding
notes may declare all the notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Company, all
outstanding notes will become due and payable without further action or notice.
Holders of the notes may not enforce the Indenture or the notes except as
provided in the Indenture. Subject to certain limitations, holders of a
majority in principal amount at maturity of the then outstanding notes may
direct the trustee in its exercise of any trust or power.

164
<PAGE>

The holders of a majority in aggregate principal amount at maturity of the
notes then outstanding by notice to the trustee may on behalf of the holders of
all of the notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the notes.

The Indenture provides that if a Default occurs and is continuing and is
known to the trustee, the trustee must mail to each holder of the notes notice
of the Default within 90 days after it occurs. Except in the case of a Default
in the payment of principal of or interest on any note, the trustee may
withhold notice if and so long as a committee of its trust officers determines
that withholding notice is not opposed to the interest of the holders of the
notes. In addition, the Company is required to deliver to the trustee, within
90 days after the end of each fiscal year, a certificate indicating whether the
signers thereof know of any Default that occurred during the previous year. The
Company is also required to deliver to the trustee, forthwith after the
occurrence thereof, written notice of any event that would constitute a
Default, the status thereof and what action the Company is taking or proposes
to take in respect thereof.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
notes, the Indenture or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each holder of notes by accepting a note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
Commission that such a waiver is against public policy.

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding notes ("Legal
Defeasance") except for:

(1) the rights of holders of outstanding notes to receive payments in
respect of the principal of, premium, if any, and interest on such notes
when such payments are due from the trust referred to below;

(2) the Company's obligations with respect to the notes concerning
issuing temporary notes, registration of notes, mutilated, destroyed, lost
or stolen notes and the maintenance of an office or agency for payment and
money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the trustee,
and the Company's obligations in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company released with respect to certain covenants that
are described in the Indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or
Event of Default with respect to the notes. In the event Covenant Defeasance
occurs, certain events (not including non-payment and bankruptcy, receivership,
rehabilitation and insolvency events with respect to the Company) described
under "--Events of Default and Remedies" will no longer constitute an Event of
Default with respect to the notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Company must irrevocably deposit with the trustee, in trust, for
the benefit of the holders of the notes, cash in United States dollars,
non-callable Government Securities, or a

165
<PAGE>

combination thereof, in such amounts as will be sufficient, in the opinion
of a nationally recognized firm of independent public accountants, to pay
the principal of, premium, if any, and interest on the outstanding notes
on the stated maturity or on the applicable redemption date, as the case
may be, and the Company must specify whether the notes are being defeased
to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Company shall have delivered to
the trustee an opinion of counsel in the United States reasonably
acceptable to the trustee confirming that (A) the Company has received
from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of the Indenture, there has been a change in
the applicable federal income tax law, in either case to the effect that,
and based thereon such opinion of counsel shall confirm that, the holders
of the outstanding notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and will
be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance
had not occurred;

(3) in the case of Covenant Defeasance, the Company shall have delivered
to the trustee an opinion of counsel in the United States reasonably
acceptable to the trustee confirming that the holders of the outstanding
notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such Covenant Defeasance had not
occurred;

(4) no Default or Event of Default shall have occurred and be continuing
on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit) or
insofar as Events of Default from bankruptcy or insolvency events with
respect to the Company are concerned, at any time in the period ending on
the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under any material
agreement or instrument (other than the Indenture) to which the Company or
any of its Restricted Subsidiaries is a party or by which the Company or
any of its Restricted Subsidiaries is bound;

(6) the Company must have delivered to the trustee an opinion of counsel
to the effect that after the 91st day following the deposit, the trust
funds will not be subject to the effect of any applicable bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally;

(7) the Company must deliver to the trustee an Officers' Certificate
stating that the deposit was not made by the Company with the intent of
preferring the holders of notes over the other creditors of the Company
with the intent of defeating, hindering, delaying or defrauding creditors
of the Company or others; and

(8) the Company must deliver to the trustee an Officers' Certificate and
an opinion of counsel, each stating that all conditions precedent provided
for relating to the Legal Defeasance or the Covenant Defeasance have been
complied with.

Transfer and Exchange

A holder may transfer or exchange notes in accordance with the Indenture.
The registrar and the trustee may require a holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a holder to pay any taxes and fees required by

166
<PAGE>

law. The Company is not required to transfer or exchange any note selected for
redemption. Also, the Company is not required to transfer or exchange any note
for a period of 15 days before a selection of notes to be redeemed.

The registered holder of a note will be treated as the owner of it for all
purposes.

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, the Indenture or
the notes may be amended or supplemented with the consent of the holders of at
least a majority in principal amount at maturity of the notes then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, notes), and any existing default or
compliance with any provision of the Indenture or the notes may be waived with
the consent of the holders of a majority in principal amount at maturity of the
then outstanding notes (including consents obtained in connection with a tender
offer or exchange offer for notes).

Without the consent of each holder affected, an amendment or waiver may not
(with respect to any notes held by a non-consenting holder):

(1) reduce the principal amount of notes whose holders must consent to an
amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any note or
alter the provisions with respect to the redemption (but not any
required repurchase in connection with an Asset Sale Offer or Change of
Control Offer) of the notes;

(3) reduce the rate of or change the time for payment of interest on any
note;

(4) waive a Default or Event of Default in the payment of principal of or
premium, if any, or interest on the notes (except a rescission of
acceleration of the notes by the holders of at least a majority in
aggregate principal amount of the notes and a waiver of the payment
default that resulted from such acceleration);

(5) make any note payable in money other than that stated in the notes;

(6) make any change in the provisions of the Indenture relating to waivers
of past Defaults or the rights of holders of notes to receive payments
of principal of or premium, if any, or interest on the notes;

(7) waive a redemption payment (but not any payment upon a required
repurchase in connection with an Asset Sale Offer or Change of Control
Offer) with respect to any note;

(8) except as provided under the caption "--Legal Defeasance and Covenant
Defeasance" or in accordance with the terms of any Subsidiary
Guarantee, release a Subsidiary Guarantor from its obligations under
its Subsidiary Guarantee or make any change in a Subsidiary Guarantee
that would adversely affect the holders of the notes; or

(9) make any change in the foregoing amendment and waiver provisions.

Notwithstanding the foregoing, without the consent of any holder of notes,
the Company and the trustee may amend or supplement the Indenture or the notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
notes in addition to or in place of certificated notes, to provide for the
assumption of the Company's obligations to holders of notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the holders of notes or that does not adversely affect
the legal rights under the Indenture of any such holder, or to comply with
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.

167

Concerning the Trustee

The Indenture contains certain limitations on the rights of the trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The trustee will be permitted to engage in
other transactions; however, if it acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue or resign.

The holders of a majority in principal amount at maturity of the then
outstanding notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the trustee,
subject to certain exceptions. The Indenture provides that in case an Event of
Default shall occur (which shall not be cured), the trustee will be required,
in the exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any holder of notes, unless such holder shall have offered to
the trustee security and indemnity satisfactory to it against any loss,
liability or expense.

[E] SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of the offering, we will have outstanding shares of
common stock ( shares if the over-allotment option is exercised in full). Of
these shares, the shares of common stock ( if the over-allotment option is
exercised in full) sold in the offering will be freely tradeable without
restriction or further registration under the Securities Act, unless held by an
"affiliate" of the Company as that term is defined in Rule 144 promulgated
under the Securities Act ("Rule 144"), which shares will be subject to the
resale limitation of Rule 144. The remaining shares of common stock ( if
the over-allotment option is exercised in full) have not been registered under
the Securities Act and may not be sold unless they are registered or unless an
exemption from registration, such as the exemption provided by Rule 144, is
available. As a result of the contractual restrictions described below and the
provisions of Rule 144, approximately shares will be eligible for sale upon
expiration of the lock-up agreements 90 days after the date of this prospectus
and approximately shares will be eligible for sale upon expiration of their
respective one-year holding periods.

We have agreed, during the period beginning from the date of this
prospectus and continuing to and including the date 90 days after the date of
this prospectus, not to offer, sell, contract to sell or otherwise dispose of
any of our securities that are substantially similar to the common stock,
including but not limited to any securities that are convertible into or
exchangeable for, or that represent the right to receive, common stock or any
such substantially similar securities, without the prior written consent of
Goldman Sachs & Co. In addition, the selling stockholders, our directors,
executive officers and certain other officers, who represent in the aggregate
approximately % of the outstanding common stock after the offering (assuming
no exercise of the underwriters' over-allotment option), will be required,
during the period beginning from the date of this prospectus and continuing to
and including the date 90 days after the date of this prospectus, not to,
directly or indirectly, offer, pledge, sell, contract to sell or otherwise
dispose of any of our securities outstanding as of the date of this prospectus,
including but not limited to any securities that are convertible into or
exchangeable for, or that represent the right to receive any common stock or
substantially similar securities, or enter into any swap or other arrangement
that transfers, in whole or in part, the economic consequences of ownership of
any of our securities, without the prior written consent of Goldman Sachs & Co.
See "Underwriting".

In general, under Rule 144 as currently in effect, a stockholder, including
an "affiliate", who has beneficially owned his or her restricted securities (as
that term is defined in Rule 144) for at least one year from the later of the
date such securities were acquired from us or (if applicable) the date they
were acquired from an affiliate, is entitled to sell, within any three-month
period, a number of such shares that does not exceed the greater of 1% of the
then outstanding shares of common stock (which will equal approximately
shares immediately after the offering) or the average weekly trading volume in
the common stock during the four calendar weeks preceding the date on which
notice of such sale was filed under Rule 144, provided certain requirements
concerning availability of public information, manner of sale and notice of
sale are satisfied. In addition, under Rule 144(k), if a period of at least two
years has elapsed between the later of the date restricted securities were
acquired from us or (if applicable) the date they were acquired from an
affiliate of ours, a stockholder who is not an affiliate of ours at the time of
sale and has not been an affiliate of ours for at least three months prior to
the sale is entitled to sell the shares immediately without compliance with the
foregoing requirements under Rule 144.

Approximately shares of common stock (approximately including shares
issuable upon conversion or exercise of outstanding securities) will be subject
to demand and piggyback registration rights. In addition, the Company estimates
that upon the expiration of the 90-day lockup period described above,
approximately shares may be sold under Rule 144, subject to the volume
restrictions contained therein.

183
<PAGE>

Except as indicated above, the Company is unable to estimate the amount,
timing and nature of future sales of outstanding common stock. No prediction
can be made as to the effect, if any, that market sales of shares of common
stock or the availability of shares for sale will have on the market price of
the common stock prevailing from time to time. Nevertheless, sales of
significant numbers of shares of common stock in the public market could
adversely affect the market price of the common stock and could impair the
Company's ability to raise capital through an offering of its equity
securities. See "Risk Factors--[E] Shares of a Substantial Number of Shares of
Common Stock After the Equity Offering Could Adversely Affect the Market Price
of the Common Stock" and "[E] Underwriting."

[D] CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following general discussion summarizes certain of the material U.S.
federal income and estate tax aspects of the purchase, ownership and
disposition of the notes. This discussion is a summary for general information
only and does not consider all aspects of U.S. federal income tax that may be
relevant to the purchase, ownership and disposition of the notes by a
prospective investor in light of such investor's personal circumstances. This
discussion also does not address the U.S. federal income tax consequences of
ownership of notes not held as capital assets within the meaning of Section
1221 of the Internal Revenue Code of 1986, as amended (the "Code"), or the U.S.
federal income tax consequences to investors subject to special treatment under
the U.S. federal income tax laws, such as dealers in securities or foreign
currency, tax-exempt entities, banks, thrifts, insurance companies, persons
that hold the notes as part of a "straddle," a "hedge" against currency risk or
a "conversion transaction," persons that have a "functional currency" other
than the U.S. dollar, and investors in pass-through entities. In addition, this
discussion is limited to the U.S. federal income tax consequences to initial
holders that purchase the notes for cash at their issue price (as defined
below) pursuant to the Offer. It does not describe any tax consequences arising
out of the tax laws of any state, local or foreign jurisdiction.

This discussion is based upon the Code, regulations of the Treasury
Department, Internal Revenue Service ("IRS") rulings and pronouncements and
judicial decisions now in effect, all of which are subject to a change
(possibly on a retroactive basis). The Company has not and will not seek any
rulings or opinions from the IRS or counsel with respect to the matters
discussed below. There can be no assurance that the IRS will not take positions
concerning the tax consequences of the purchase, ownership or disposition of
the notes which are different from those discussed herein.

Persons considering the purchase of notes should consult their own advisors
concerning the application of U.S. federal income tax laws, as well as the laws
of any state, local or foreign taxing jurisdiction, to their particular
situations.

U.S. Holders

The following discussion is limited to the U.S. federal income tax
consequences relevant to a "U.S. Holder," which means a beneficial owner of a
note that is (i) a citizen or resident of the United States, (ii) a corporation
or other entity taxable as a corporation created or organized under the laws of
the United States or any political subdivision thereof or therein, (iii) an
estate the income of which is subject to U.S. federal income taxation
regardless of its sources, (iv) a trust if a U.S. court is able to exercise
primary jurisdiction over administration of the trust and one or more U.S.
persons have authority to control all substantial decisions of the trust or (v)
otherwise subject to U.S. federal income taxation with respect to its worldwide
income on a net income basis. Certain U.S. federal income tax consequences
relevant to a holder other than a U.S. Holder are discussed separately below.

Interest and Original Issue Discount

The notes will be issued with original issue discount ("OID"). OID is the
excess of (i) the stated redemption price at maturity of a note over (ii) its
issue price.

The "stated redemption price at maturity" of a note is the sum of all
payments provided by the instrument. The "issue price" of a note is the first
price at which a substantial amount of the notes are sold to the public for
cash (excluding sales to bond houses, brokers or similar persons or
organizations acting in the capacity as underwriters, placement agents or
wholesalers).

A U.S. Holder is required to include OID in income as ordinary interest as
it accrues under a constant yield method in advance of receipt of the cash
payments attributable to such income, regardless of such U.S. Holder's regular
method of accounting. A U.S. Holder will not be required to report separately
as taxable income actual distributions of stated interest with respect to the
notes. In

185
<PAGE>

general, the amount of OID included in income by the holder of a note is the
sum of the daily portions of OID for each day during the taxable year (or
portion of the taxable year) on which such holder held such note. The "daily
portion" is determined by allocating the OID for an accrual period ratably to
each day in that accrual period. The "accrual period" for a note may be of any
length and may vary in length over the term of a note, provided that each
accrual period is no longer than one year and each scheduled payment of
principal or interest occurs either on the first or final day of an accrual
period.

The amount of OID for an accrual period is generally equal to the product
of the note's adjusted issue price at the beginning of such accrual period and
its yield to maturity. The "adjusted issue price" of a note at the beginning of
any accrual period is the sum of the issue price of the note plus the amount of
OID allocable to all prior accrual periods minus the amount of any prior
payments on the note. Under the constant yield method of determining OID, a
U.S. Holder generally will have to include in income increasingly greater
amounts of OID in successive accrual periods.

Applicable High Yield Discount Obligation
The OID on any obligation that constitutes an "applicable high yield
discount obligation" is not deductible until paid. An "applicable high yield
discount obligation" is any debt instrument that (i) has a maturity date which
is more than five years from the date of issue, (ii) has a yield to maturity
which equals or exceeds the applicable Federal rate ("AFR") (as set forth in
Section 1274(d) of the Code) for the calendar month in which the obligation is
issued plus five percentage points and (iii) has "significant original issue
discount." The AFR is an interest rate, announced monthly by the IRS, that is
based on the yield of debt obligations issued by the U.S. Treasury, which AFR
is 5.23% for March, 1999. A debt instrument generally has "significant original
issue discount" if, as of the close of any accrual period ending more than five
years after the date of issue, the excess of the interest (including OID) that
has accrued on the obligation over the interest (including OID) that is
required to be paid thereunder exceeds the product of the issue price of the
instrument and its yield to maturity. Moreover, if the debt instrument's yield
to maturity exceeds the AFR plus six percentage points, a ratable portion of
the issuing corporation's deduction for OID (the "Disqualified OID") (based on
the portion of the yield to maturity that exceeds the AFR plus six percentage
points) will be denied. The Disqualified OID will be treated as a dividend
generally eligible for the dividends-received deduction in the case of
corporate holders to the extent it would have been so treated had such amount
been distributed by the issuing corporation with respect to its stock.

Sale, Exchange or Redemption of the Notes

Upon the sale, exchange, retirement or other disposition of a note, a U.S.
Holder will generally recognize taxable capital gain or loss equal to the
difference between (i) the amount realized on the disposition (except to the
extent that amounts received are attributable to accrued interest, which
portion of the consideration would be taxed as ordinary income if the interest
was previously untaxed) and (ii) the U.S. Holder's adjusted tax basis in the
note. A U.S. Holder's adjusted tax basis in a note generally will equal the
cost of the note to the U.S. Holder increased by any OID included in income
through the date of disposition and decreased by any payments received on the
notes. In the case of a U.S. Holder who is an individual, such capital gain
will be subject to tax at a maximum rate of 20% if the note has been held for
more than 12 months at the time of the sale, exchange, retirement or other
disposition.

A U.S. Holder will not recognize any taxable gain or loss on the exchange
of notes for new notes pursuant to the Exchange Offer.

Information Reporting and Backup Withholding

U.S. Holders of notes may be subject, under certain circumstances, to
information reporting and "backup withholding" at a 31% rate with respect to
cash payments in respect of principal (and

186
<PAGE>

premium, if any), interest (including OID) and the gross proceeds from
dispositions of notes. Backup withholding applies only if the U.S. Holder (i)
fails to furnish its social security or other taxpayer identification number
("TIN") within a reasonable time after a request therefor, (ii) furnishes an
incorrect TIN, (iii) fails to report properly interest or dividends, or (iv)
fails, under certain circumstances, to provide a certified statement, signed
under penalty of perjury, that the TIN provided is its correct number and that
it is not subject to backup withholding. Any amount withheld from a payment to
a U.S. Holder under the backup withholding rules is allowable as a credit (and
may entitle such holder to a refund) against such U.S. Holder's U.S. federal
income tax liability, provided that the required information is furnished to
the IRS. Certain persons are exempt from backup withholding, including
corporations and financial institutions. U.S. Holders of notes should consult
their tax advisors as to their qualification for exemption from backup
withholding and the procedure for obtaining such exemption.

The Company will furnish annually to the IRS and to record holders of the
notes (to whom it is required to furnish such information) information relating
to the amount of OID and interest, as applicable.

Non-U.S. Holders

The following discussion is limited to the U.S. federal income tax
consequences relevant to a holder of a note that is not a U.S. Holder (a "Non-
U.S. Holder").

Subject to the discussion of backup withholding below, payments of interest
(including OID) on a note to any Non-U.S. Holder will generally not be subject
to U.S. federal income or withholding tax, provided that (1) the holder is not
(i) an actual or constructive owner of 10% or more of the total voting power of
all voting stock of the Company or (ii) a controlled foreign corporation
related (directly or indirectly) to the Company through stock ownership or
(iii) a foreign tax-exempt organization or a foreign private foundation for
U.S. federal income tax purposes, (2) such interest payments are not
effectively connected with the conduct by the Non-U.S. Holder of a trade or
business within the United States and (3) the Company or its paying agent
receives (i) from the Non-U.S. Holder, a properly completed Form W-8 (or
substitute Form W-8) under penalties of perjury which provides the Non-U.S.
Holder's name and address and certifies that the Non-U.S. Holder of the note is
a Non-U.S. Holder or (ii) from a security clearing organization, bank or other
financial institution that holds the notes in the ordinary course of its trade
or business (a "financial institution") on behalf of the Non-U.S. Holder,
certification under penalties of perjury that such a Form W-8 (or substitute
Form W-8) has been received by it, or by another such financial institution,
from the Non-U.S. Holder, and a copy of the Form W-8 (or substitute Form W-8)
is furnished to the payor.

A Non-U.S. Holder that does not qualify for exemption from withholding
under the preceding paragraph generally will be subject to withholding of U.S.
federal income tax at the rate of 30% (or lower applicable treaty rate) on
payments of interest (including OID) on the notes.

If the payments of interest (including OID) on a note are effectively
connected with the conduct by a Non-U.S. Holder of a trade or business in the
United States, such payments will be subject to U.S. federal income tax on a
net basis at the rates applicable to U.S. persons generally (and, with respect
to corporate holders, may also be subject to a 30% branch profits tax). If
payments are subject to U.S. federal income tax on a net basis in accordance
with the rules described in the preceding sentence, such payments will not be
subject to U.S. withholding tax so long as the holder provides the Company or
its paying agent with a properly executed Form 4224.

Non-U.S. Holders should consult any applicable income tax treaties, which
may provide for a lower rate of withholding tax, exemption from or reduction of
branch profits tax, or other rules different from those described above.

187
<PAGE>

Sale, Exchange or Redemption of Notes

Subject to the discussion concerning backup withholding, any gain realized
by a Non-U.S. Holder on the sale, exchange, retirement or other disposition of
a note generally will not be subject to U.S. federal income tax, unless (i)
such gain is effectively connected with the conduct by such Non-U.S. Holder of
a trade or business within the United States, (ii) the Non-U.S. Holder is an
individual who is present in the United States for 183 days or more in the
taxable year of the disposition and certain other conditions are satisfied or
(iii) the Non-U.S. Holder is subject to tax pursuant to the provisions of U.S.
federal tax law applicable to certain U.S. expatriates.

Federal Estate Tax

Notes held (or treated as held) by an individual who is a Non-U.S. Holder
at the time of his or her death will not be subject to U.S. federal estate tax
provided that (i) the individual does not actually or constructively own 10% or
more of the total voting power of all voting stock of the Company and (ii)
income on the note was not effectively connected with the conduct by such Non-
U.S. Holder of a trade or business within the United States.

Information Reporting and Backup Withholding

The Company must report annually to the IRS and to each Non-U.S. Holder any
interest (including OID) that is subject to withholding or that is exempt from
U.S. withholding tax. Copies of those information returns may also be made
available, under the provisions of a specific treaty or agreement, to the tax
authorities of the country in which the Non-U.S. Holder resides.

The regulations provide that backup withholding (which generally is a
withholding tax imposed at the rate of 31% on payments to persons that fail to
furnish certain required information) and information reporting will not apply
to payments made in respect of the notes by the Company to a Non-U.S. Holder,
if the holder certifies as to its non-U.S. status under penalties of perjury or
otherwise establishes an exemption (provided that neither the Company nor its
paying agent has actual knowledge that the holder is a U.S. person or that the
conditions of any other exemption are not, in fact, satisfied).

The payment of the proceeds from the disposition of notes to or through the
U.S. office of any broker, U.S. or foreign, will be subject to information
reporting and possible backup withholding unless the owner certifies as to its
non-U.S. status under penalty of perjury or otherwise establishes an exemption,
provided that the broker does not have actual knowledge that the holder is a
U.S. person or that the conditions of any other exemption are not, in fact,
satisfied. The payment of the proceeds from the disposition of a note to or
through a non-U.S. office of a non-U.S. broker that is not a U.S. related
person will not be subject to information reporting or backup withholding. For
this purpose, a "U.S. related person" is (i) a "controlled foreign corporation"
for U.S. federal income tax purposes or (ii) a foreign person 50% or more of
whose gross income from all sources for the three-year period ending with the
close of its taxable year preceding the payment (or for such part of the period
that the broker has been in existence) is derived from activities that are
effectively connected with the conduct of a U.S. trade or business.

In the case of the payment of proceeds from the disposition of notes to or
through a non-U.S. office of a broker that is either a U.S. person or a U.S.
related person, the regulations require information reporting on the payment
unless the broker has documentary evidence in its files that the owner is a
Non-U.S. Holder and the broker has no knowledge to the contrary. Backup
withholding will not apply to payments made through foreign offices of a broker
that is a U.S. person or a U.S. related person (absent actual knowledge that
the payee is a U.S. person).

Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. Holder will be allowed as a refund or a credit against such Non-U.S.
Holder's U.S. federal income tax liability, provided that the requisite
procedures are followed.

The Treasury Department recently promulgated final regulations regarding
the withholding and information reporting rules discussed above. In general,
the final regulations do not significantly alter the substantive withholding
and information reporting requirements but rather unify current certification
procedures and forms and clarify reliance standards. The final regulations are
generally effective for payments made after December 31, 1999, subject to
certain transition rules. Non-U.S. Holders should consult their own tax
advisors with respect to the impact, if any, of the final regulations.

[E] CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following general discussion summarizes certain of the material U.S.
federal income and estate tax aspects of the ownership and disposition of
common stock applicable to Non-U.S. Holders (as defined) of common stock. In
general, a "Non-U.S. Holder" is a person other than: (i) a citizen or resident
of the United States, (ii) a corporation or other entity taxable as a
corporation created or organized under the laws of the United States or any
political subdivision thereof or therein, (iii) an estate the income of which
is subject to U.S. federal income taxation regardless of its sources or (iv) a
trust if a U.S. court is able to exercise primary jurisdiction over
administration of the trust and one or more U.S. persons have authority to
control all substantial decisions of the trust. The discussion is based upon
the Internal Revenue Code of 1986, as amended (the "Code"), regulations of the
Treasury Department, Internal Revenue Service ("IRS") rulings and
pronouncements and judicial decisions now in effect, all of which are subject
to change (possibly on a retroactive basis). The discussion does not address
aspects of U.S. federal taxation other than income and estate taxation and does
not address all aspects of federal income and estate taxation. The discussion
does not consider any specific facts or circumstances that may apply to a
particular Non-U.S. Holder and does not address all aspects of U.S. federal
income tax law that may be relevant to Non-U.S. Holders that may be subject to
special treatment under such law (for example, insurance companies, tax-exempt
organizations, financial institutions, broker-dealers or certain U.S.
expatriates).

Persons considering the purchase of common stock should consult their own
tax advisors concerning the application of U.S. federal income tax laws, as
well as the laws of any state, local or foreign taxing jurisdiction to their
particular situations.

Dividends

In general, the gross amount of dividends paid to a Non-U.S. Holder will be
subject to U.S. withholding tax at a 30% rate (or any lower rate prescribed by
an applicable tax treaty) unless the dividends are (i) effectively connected
with a trade or business carried on by the Non-U.S. Holder within the United
States and a Form 4224 is filed with the withholding agent or (ii) if a tax
treaty applies, are attributable to a United States permanent establishment of
the Non-U.S. Holder. If either exception applies, the dividend will be taxed at
ordinary U.S. federal income tax rates. A Non-U.S. Holder may be required to
satisfy certain certification requirements in order to claim the benefit of an
applicable treaty rate or otherwise claim a reduction of, or exemption from,
the withholding obligation pursuant to the above described rules. In the case
of a Non-U.S. Holder that is a corporation, effectively connected income may
also be subject to an additional branch profits tax (which is generally imposed
on a foreign corporation at a rate of 30% of the deemed repatriation from the
United States of "effectively connected earnings and profits" or such lower
rate as an applicable tax treaty may provide). To the extent a distribution
exceeds current or accumulated earnings or profits ("E&P"), it will be treated
first as a return of the holder's basis to the extent thereof, and then as a
gain from the sale of a capital asset. Any withholding tax on a distribution in
excess of the Company's E&P is refundable to the Non-U.S. Holder upon filing an
appropriate claim with the IRS.

Disposition of Common Stock

Generally, a Non-U.S. Holder will not be subject to U.S. federal income tax
on any gain recognized upon the disposition of common stock unless: (i) the
gain is effectively connected with a trade or business carried on by the Non-
U.S. Holder within the United States, or, alternatively, if a tax treaty
applies, attributable to a United States permanent establishment maintained by
the Non-U.S. Holder (in which case such gain will be subject to tax at the
rates and in the manner applicable to U.S. persons, and, if the holder is a
foreign corporation, the branch profits tax may also apply), (ii) the common
stock is disposed of by an individual Non-U.S. Holder, who holds the common
stock as a capital asset and is present in the United States for 183 days or
more in the taxable year of the disposition and certain other conditions are
met (in which case such gain will be subject to a flat 30%

190
<PAGE>

tax, which may be offset by United States source capital losses (even though
the individual is not considered a resident of the United States)) or (iii) (A)
the Company is or has been a "U.S. real property holding corporation" within
the meaning of Section 897(c)(2) of the Code at any time within the shorter of
the five-year period preceding such disposition or such Non-U.S. Holder's
holding period and (B) assuming that the common stock is "regularly traded on
an established securities market" for U.S. federal income tax purposes, the
Non-U.S. Holder held, directly or indirectly, at any time during the applicable
period from clause (A) above, including on the date of disposition, more than
5% of the outstanding common stock. Although the Company believes it currently
is not a U.S. real property holding corporation, the Company anticipates
becoming such a corporation as a result of the proposed joint venture with BAM
and the Proposed BellSouth Transaction. Non-U.S. Holders should consult
applicable treaties, which may exempt from U.S. taxation gains realized upon
the disposition of common stock in certain cases.

Estate Tax

Common stock owned (or treated as owned) by an individual Non-U.S. Holder
at the time of death will be includible in the individual's gross estate for
U.S. federal estate tax purposes, and may be subject to U.S. federal estate
tax, unless an applicable treaty provides otherwise.

Information Reporting and Backup Withholding

On October 6, 1997, the IRS issued final regulations relating to
withholding, information reporting and backup withholding that unify current
certification procedures and forms and clarify reliance standards (the "Final
Regulations"). The Final Regulations generally will be effective with respect
to payments made after December 31, 1999.

Except as provided below, this section describes rules applicable to
payments made on or before December 31, 1999. Backup withholding (which
generally is a withholding tax imposed at the rate of 31% on certain payments
to persons that fail to furnish the information required under the U.S.
information reporting and backup withholding rules) generally will not apply to
(i) dividends paid to Non-U.S. Holders that are subject to the 30% withholding
discussed above (or that are not so subject because a tax treaty applies that
reduces or eliminates such 30% withholding) or (ii) dividends paid on the
common stock to a Non-U.S. Holder at an address outside the United States
(unless the payor has actual knowledge that the payee is a U.S. person). The
Company will be required to report annually to the IRS and to each Non-U.S.
Holder the amount of dividends paid to, and the tax withheld with respect to,
such holder, regardless of whether any tax was actually withheld or whether
withholding was required. This information may also be made available to the
tax authorities in the Non-U.S. Holder's country of residence.

In the case of a Non-U.S. Holder that sells common stock to or through a
U.S. office of a broker, the broker must backup withhold at a rate of 31% and
report the sale to the IRS, unless the holder certifies its Non-U.S. status
under penalties of perjury or otherwise establishes an exemption. In the case
of a Non-U.S. Holder that sells common stock to or through the foreign office
of a U.S. broker, or a foreign broker with certain types of relationships to
the United States, the broker must report the sale to the IRS (but not backup
withhold) unless the broker has documentary evidence in its files that the
seller is a Non-U.S. Holder or certain other conditions are met, or the holder
otherwise establishes an exemption. A Non-U.S. Holder will generally not be
subject to information reporting or backup withholding if such Non-U.S. Holder
sells the common stock to or through a foreign office of a non-U.S. broker.

Any amount withheld under the backup withholding rules from a payment to a
holder is allowable as a credit against the holder's U.S. federal income tax,
which may entitle the holder to a refund, provided that the holder furnishes
the required information to the IRS. In addition, certain penalties may be
imposed by the IRS on a holder who is required to supply information but does
not do so in the proper manner.

191
<PAGE>

The Final Regulations eliminate the general, current legal presumption that
dividends paid to an address in a foreign country are paid to a resident of
that country. In addition, the Final Regulations impose certain certification
and documentation requirements on Non-U.S. Holders claiming the benefit, under
a tax treaty, of a reduced withholding rate with respect to dividends.

Prospective purchasers of the common stock are urged to consult their own
tax advisors as to the effect, if any, of the Final Regulations on their
purchase, ownership and disposition of the common stock.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
Crown Castle International Corp.:

We have audited the accompanying consolidated balance sheets of Crown
Castle International Corp. and subsidiaries as of December 31, 1997 and 1998,
and the related consolidated statements of operations and comprehensive loss,
cash flows and stockholders' equity (deficit) for each of the years in the
three-year period ended December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Crown
Castle International Corp. and subsidiaries as of December 31, 1997 and 1998,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1998, in conformity with generally
accepted accounting principles.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Crown Castle
International Corp. and its majority and wholly owned subsidiaries,
collectively referred to herein as the "Company." All significant intercompany
balances and transactions have been eliminated in consolidation. Certain
reclassifications have been made to the prior year's financial statements to be
consistent with the presentation in the current year.

The Company owns, operates and manages wireless communications sites and
broadcast transmission networks. The Company also provides complementary
services to its customers, including network design, radio frequency
engineering, site acquisition, site development and construction, antenna
installation and network management and maintenance. The Company's
communications sites are located throughout the United States, in Puerto Rico
and in the United Kingdom. In the United States and Puerto Rico, the Company's
primary business is the leasing of antenna space to wireless operators under
long-term contracts. In the United Kingdom, the Company's primary business is
the operation of television and radio broadcast transmission networks; the
Company also leases antenna space to wireless operators in the United Kingdom.

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, the
disclosure of contingent assets and liabilities as of the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Summary of Significant Accounting Policies

Cash Equivalents
Cash equivalents consist of highly liquid investments with original
maturities of three months or less.

Inventories
Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out (FIFO) method.

Property and Equipment
Property and equipment is stated at cost, net of accumulated depreciation.
Depreciation is computed utilizing the straight-line method at rates based upon
the estimated useful lives of the various classes of assets. Additions,
renewals and improvements are capitalized, while maintenance and repairs are
expensed. Upon the sale or retirement of an asset, the related cost and
accumulated depreciation are removed from the accounts and any gain or loss is
recognized.

In March 1995, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of
("SFAS 121"). SFAS 121 requires that long-lived assets and certain identifiable
intangibles be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. SFAS 121 was

F-7
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

effective for fiscal years beginning after December 15, 1995. The adoption of
SFAS 121 by the Company in 1996 did not have a material impact on its
consolidated financial statements.

Goodwill and Other Intangible Assets
Goodwill and other intangible assets represents the excess of the purchase
price for an acquired business over the allocated value of the related net
assets (see Note 2). Goodwill is amortized on a straight-line basis over a
twenty year life. Other intangible assets (principally the value of existing
site rental contracts at Crown Communications) are amortized on a straight-line
basis over a ten year life. The carrying value of goodwill and other intangible
assets will be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of the acquired assets may not
be recoverable. If the sum of the estimated future cash flows (undiscounted)
expected to result from the use and eventual disposition of an asset is less
than the carrying amount of the asset, an impairment loss is recognized.
Measurement of an impairment loss is based on the fair value of the asset.

Deferred Financing Costs
Costs incurred to obtain financing are deferred and amortized over the
estimated term of the related borrowing. At December 31, 1997, other accrued
liabilities includes $1,160,000 of such costs related to the issuance of the
Company's 10 5/8% Senior Discount Notes.

Revenue Recognition
Site rental revenues are recognized on a monthly basis under lease or
management agreements with terms ranging from 12 months to 25 years. Broadcast
transmission revenues are recognized on a monthly basis under transmission
contracts with terms ranging from 8 years to 12 years.

Network services revenues from site development, construction and antennae
installation activities are recognized under a method which approximates the
completed contract method. This method is used because these services are
typically completed in three months or less and financial position and results
of operations do not vary significantly from those which would result from use
of the percentage-of-completion method. These services are considered complete
when the terms and conditions of the contract or agreement have been
substantially completed. Costs and revenues associated with installations not
complete at the end of a period are deferred and recognized when the
installation becomes operational. Any losses on contracts are recognized at
such time as they become known.

Network services revenues from design, engineering, site acquisition, and
network management and maintenance activities are recognized under service
contracts with customers which provide for billings on a time and materials,
cost plus profit, or fixed price basis. Such contracts typically have terms
from six months to two years. Revenues are recognized as services are performed
with respect to the time and materials contracts. Revenues are recognized using
the percentage-of-completion method for cost plus profit and fixed price
contracts, measured by the percentage of contract costs incurred to date
compared to estimated total contract costs. Provisions for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined.

Corporate Development Expenses
Corporate development expenses represent costs incurred in connection with
acquisitions and development of new business initiatives.

F-8

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Income Taxes
The Company accounts for income taxes using an asset and liability
approach, which requires the recognition of deferred income tax assets and
liabilities for the expected future tax consequences of events that have been
recognized in the Company's financial statements or tax returns. Deferred
income tax assets and liabilities are determined based on the temporary
differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates.

Per Share Information
Per share information is based on the weighted-average number of common
shares outstanding during each period for the basic computation and, if
dilutive, the weighted-average number of potential common shares resulting from
the assumed conversion of outstanding stock options, warrants and convertible
preferred stock for the diluted computation.

A reconciliation of the numerators and denominators of the basic and
diluted per share computations is as follows:

<TABLE>

====== ======== ========
Loss per common share--basic and diluted........ $(0.27) $ (2.27) $ (1.02)
====== ======== ========
</TABLE>

The calculations of common shares outstanding for the diluted computations
exclude the following potential common shares as of December 31, 1998: (i)
options to purchase 16,585,197 shares of common stock at exercise prices
ranging from $-0- to $17.625 per share; (ii) warrants to purchase 1,314,990
shares of common stock at an exercise price of $7.50 per share; and (iii)
shares of Castle Transmission Services (Holdings) Ltd ("CTI") stock which are
convertible into 17,443,500 shares of common stock. The inclusion of such
potential common shares in the diluted per share computations would be
antidilutive since the Company incurred net losses for each of the three years
in the period ended December 31, 1998.

Foreign Currency Translation
CTI uses the British pound as the functional currency for its operations.
The Company translates CTI's results of operations using the average exchange
rate for the period, and translates CTI's assets and liabilities using the
exchange rate at the end of the period. The cumulative effect of changes in the
exchange rate is recorded as a translation adjustment in stockholders' equity.

Financial Instruments
The carrying amount of cash and cash equivalents approximates fair value
for these instruments. The estimated fair value of the 10 5/8% Senior Discount
Notes and the 9% Guaranteed

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Bonds is based on quoted market prices, and the estimated fair value of the
other long-term debt is determined based on the current rates offered for
similar borrowings. The estimated fair value of the interest rate swap
agreement is based on the amount that the Company would receive or pay to
terminate the agreement at the balance sheet date. The estimated fair values of
the Company's financial instruments, along with the carrying amounts of the
related assets (liabilities), are as follows:

Interest rate swap agreement......... -- (97) -- (47)
</TABLE>

The Company's interest rate swap agreement is used to manage interest rate
risk. The net settlement amount resulting from this agreement is recognized as
an adjustment to interest expense. The Company does not hold or issue
derivative financial instruments for trading purposes.

Stock Options
In October 1995, the FASB issued Statement of Financial Accounting
Standards No. 123, Accounting for Stock-Based Compensation ("SFAS 123"). SFAS
123 establishes alternative methods of accounting and disclosure for employee
stock-based compensation arrangements. The Company has elected to continue the
use of the "intrinsic value based method" of accounting for its employee stock
option plans (see Note 9). This method does not result in the recognition of
compensation expense when employee stock options are granted if the exercise
price of the options equals or exceeds the fair market value of the stock at
the date of grant. See Note 9 for the disclosures required by SFAS 123.

Recent Accounting Pronouncements
In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 establishes
standards for the reporting and display of comprehensive income in a company's
financial statements. Comprehensive income includes all changes in a company's
equity accounts (including net income or loss) except investments by, or
distributions to, the company's owners. Items which are components of
comprehensive income (other than net income or loss) include foreign currency
translation adjustments, minimum pension liability adjustments and unrealized
gains and losses on certain investments in debt and equity securities. The
components of comprehensive income must be reported in a financial statement
that is displayed with the same prominence as other financial statements. SFAS
130 is effective for fiscal years beginning after December 15, 1997. The
Company has adopted the requirements of SFAS 130 in its financial statements
for 1998.

In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, Disclosures about Segments of an Enterprise and Related Information
("SFAS 131"). SFAS 131 establishes standards for the way that public companies
report, in their annual financial statements, certain information about their
operating segments, their products and services, the geographic areas in which
they operate and their major customers. SFAS 131 also requires that certain
information about operating segments be reported in interim financial
statements. SFAS 131 is effective for periods beginning after December 15,
1997. The Company has adopted the requirements of SFAS 131 in its financial
statements for the year ended December 31, 1998 (see Note 13).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

In April 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued Statement of Position 98-5,
Reporting on the Costs of Start-Up Activities ("SOP 98-5"). SOP 98-5 requires
that costs of start-up activities be charged to expense as incurred and broadly
defines such costs. The Company has deferred certain costs incurred in
connection with potential business initiatives and new geographic markets, and
SOP 98-5 will require that such deferred costs be charged to results of
operations upon its adoption. SOP 98-5 is effective for fiscal years beginning
after December 15, 1998. The Company will adopt the requirements of SOP 98-5 as
of January 1, 1999. The cumulative effect of the change in accounting principle
for the adoption of SOP 98-5 will result in a charge to results of operations
in the Company's financial statements for the three months ending March 31,
1999; it is currently estimated that such charge will amount to approximately
$2,300,000.

In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS
133"). SFAS 133 requires that derivative instruments be recognized as either
assets or liabilities in the consolidated balance sheet based on their fair
values. Changes in the fair values of such derivative instruments will be
recorded either in results of operations or in other comprehensive income,
depending on the intended use of the derivative instrument. The initial
application of SFAS 133 will be reported as the effect of a change in
accounting principle. SFAS 133 is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. The Company will adopt the requirements of
SFAS 133 in its financial statements for the three months ending March 31,
2000. The Company has not yet determined the effect that the adoption of SFAS
133 will have on its consolidated financial statements.

2.Acquisitions

During the three years in the period ended December 31, 1998, the Company
consummated a number of business acquisitions which were accounted for using
the purchase method. Results of operations and cash flows of the acquired
businesses are included in the consolidated financial statements for the
periods subsequent to the respective dates of acquisition.

Motorola, Inc. ("Motorola")
On June 28, 1996, the Company acquired fifteen telecommunications towers
and related assets, and assets related to specialized mobile radio and
microwave services, from Motorola in Puerto Rico. The purchase price consisted
of $9,919,000 in cash. Motorola provided certain management services related to
these assets for a period of ninety days after the closing date. Management
fees for such services amounted to $57,000 for the year ended December 31,
1996.

Other Acquisitions
During 1996, the Company acquired a number of other telecommunications
towers and related equipment from various sellers. The aggregate total purchase
price for these acquisitions of $1,039,000 consisted of $1,006,000 in cash and
a $33,000 payable to a seller.

TEA Group Incorporated and TeleStructures, Inc. (collectively, "TEA")
On May 12, 1997, the Company acquired all of the common stock of TEA. TEA
provides telecommunications site selection, acquisition, design and development
services. The purchase price of $14,215,000 consisted of $8,120,000 in cash (of
which $2,001,000 was paid in 1996 as an option payment), promissory notes
payable to the former stockholders of TEA totaling $1,872,000, the assumption
of $1,973,000 in outstanding debt and 535,710 shares of the Company's Class B

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Common Stock valued at $2,250,000 (the estimated fair value of such common
stock on that date). The Company recognized goodwill of $9,568,000 in
connection with this acquisition. The Company repaid the promissory notes with
a portion of the proceeds from the issuance of its 10 5/8% Senior Discount
Notes (see Note 5).

Crown Communications ("CCM"), Crown Network Systems, Inc. ("CNS") and
Crown Mobile Systems, Inc. ("CMS") (collectively, "Crown")
On July 11, 1997, the Company entered into an asset purchase and merger
agreement with the owners of Crown. On August 15, 1997, such agreement was
amended and restated, and the Company acquired (i) substantially all of the
assets, net of outstanding liabilities, of CCM and (ii) all of the outstanding
common stock of CNS and CMS. Crown provides network services, which includes
site selection and acquisition, antenna installation, site development and
construction, network design and site maintenance, and owns and operates
telecommunications towers and related assets. The purchase price of
$185,021,000 consisted of $27,843,000 in cash, a short-term promissory note
payable to the former owners of Crown for $76,230,000, the assumption of
$26,009,000 in outstanding debt and 7,325,000 shares of the Company's Class B
Common Stock valued at $54,939,000 (the estimated fair value of such common
stock on that date). The Company recognized goodwill and other intangible
assets of $146,103,000 in connection with this acquisition. The Company
financed the cash portion of the purchase price with proceeds from the
issuance of redeemable preferred stock (see Note 8), and repaid the promissory
note with proceeds from the issuance of additional redeemable preferred stock
and borrowings under the Senior Credit Facility (see Note 5).

In 1997, the Company organized Crown Communication Inc. ("CCI," a Delaware
corporation) as a wholly owned subsidiary to own the net assets acquired from
CCM and the common stock of CNS and CMS. In January 1998, the Company merged
Castle Tower Corporation ("CTC," a wholly owned operating subsidiary) with and
into CCI, establishing CCI as the principal domestic operating subsidiary of
the Company.

CTI
On April 24, 1998, the Company entered into a share exchange agreement
with certain shareholders of CTI pursuant to which certain of CTI's
shareholders agreed to exchange their shares of CTI for shares of the Company.
On August 18, 1998, the exchange was consummated and the Company's ownership
of CTI increased from approximately 34.3% to 80%. The Company issued
20,867,700 shares of its Common Stock and 11,340,000 shares of its Class A
Common Stock, with such shares valued at an aggregate of $418,700,000 (based
on the price per share to the public in the Company's initial public offering
as discussed in Note 9). The Company recognized goodwill of $344,204,000 in
connection with this transaction, which was accounted for as an acquisition
using the purchase method. CTI's results of operations and cash flows are
included in the consolidated financial statements for the period subsequent to
the date the exchange was consummated.

Pro Forma Results of Operations (Unaudited)
The following unaudited pro forma summary presents consolidated results of
operations for the Company as if (i) the TEA and Crown acquisitions had been
consummated as of January 1, 1997 and (ii) the share exchange with CTI's
shareholders had been consummated as of January 1 for both 1997 and 1998.
Appropriate adjustments have been reflected for depreciation and amortization,
interest expense, amortization of deferred financing costs, income taxes and

of CTI. The purchase price of $14,473,000 consisted of $9,813,000 in cash, the
repayment of $2,396,000 in outstanding debt and 358,678 shares of the Company's
common stock valued at $2,264,000 (the market value of such common stock on
that date).

Agreement with Bell Atlantic Mobile ("BAM")
On December 8, 1998, the Company entered into an agreement with BAM to form
a joint venture ("Crown Atlantic") to own and operate a significant majority of
BAM's towers. Upon formation of Crown Atlantic (which is currently expected to
occur in March 1999), (i) the Company will contribute to Crown Atlantic
$250,000,000 in cash and 15,575,046 shares of its Common Stock in exchange for
a 62.3% ownership interest in Crown Atlantic, (ii) Crown Atlantic will borrow
$180,000,000 under a committed $250,000,000 revolving credit facility, and
(iii) BAM will contribute to Crown Atlantic approximately 1,427 towers in
exchange for a cash distribution of $380,000,000 from Crown Atlantic and a
37.7% ownership interest in Crown Atlantic. Upon dissolution of Crown Atlantic,
BAM would receive (i) the shares of the Company's Common Stock contributed to
Crown Atlantic and (ii) a payment (either in cash or in shares of the Company's
Common Stock, at the Company's election) equal to 14.0% of the fair market
value of Crown Atlantic's other net assets; the Company would then receive the
remaining assets and liabilities of Crown Atlantic. The Company will account
for its investment in Crown Atlantic as an acquisition using the purchase
method, and will include Crown Atlantic's results of operations and cash flows
in the Company's consolidated financial statements for periods subsequent to
formation.

4.Investments in Affiliates

Investment in CTI
On February 28, 1997, the Company used a portion of the net proceeds from
the sale of the Series C Convertible Preferred Stock (see Note 8) to purchase
an ownership interest of approximately 34.3% in CTI (a company incorporated
under the laws of England and Wales). The Company led a consortium of investors
which provided the equity financing for CTI. The funds invested by the
consortium were used by CTI to purchase, through a wholly owned subsidiary, the
domestic broadcast transmission division of the British Broadcasting
Corporation (the "BBC"). The cost of the Company's investment in CTI amounted
to approximately $57,542,000. The Company accounted for its investment in CTI
utilizing the equity method of accounting prior to the consummation of the
share exchange agreement with CTI's shareholders in August 1998 (see Note 2).

In March 1997, as compensation for leading the investment consortium, the
Company received a fee from CTI amounting to approximately $1,165,000. This fee
was recorded as other income by the Company when received. In addition, the
Company received approximately $1,679,000 from CTI as reimbursement for costs
incurred prior to the closing of the purchase from the BBC.

In June 1997, as compensation for the successful completion of the
investment in CTI and certain other acquisitions and investments, the Company
paid bonuses to two of its executive officers totaling $913,000. These bonuses
are included in corporate development expenses on the Company's consolidated
statement of operations.

Senior Credit Facility
CTC had a credit agreement with a bank (as amended, the "Bank Credit
Agreement") which consisted of secured revolving lines of credit (the
"Revolving Credit Facility") and a $2,300,000 term note (the "Term Note"). On
January 17, 1997, the Bank Credit Agreement was amended to: (i) increase the
available borrowings under the Revolving Credit Facility to $50,000,000; (ii)
repay the

F-15
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Term Note, along with accrued interest thereon, with borrowings under the
Revolving Credit Facility; and (iii) extend the termination date for the Bank
Credit Agreement to December 31, 2003. Available borrowings under the Revolving
Credit Facility were generally to be used to construct new towers and to
finance a portion of the purchase price for towers and related assets. The
amount of available borrowings was determined based on the current financial
performance (as defined) of: (i) the assets to be acquired; and (ii) assets
acquired in previous acquisitions. In addition, up to $5,000,000 of borrowing
availability under the Revolving Credit Facility could be used for letters of
credit.

In October 1997, the Bank Credit Agreement was amended to (i) increase the
available borrowings to $100,000,000; (ii) include the lending bank under
Crown's bank credit agreement as a participating lender; and (iii) extend the
maturity date to December 31, 2004 (as amended, the "Senior Credit Facility").
On October 31, 1997, additional borrowings under the Senior Credit Facility,
along with the proceeds from the October issuance of Senior Preferred Stock
(see Note 8), were used to repay (i) the promissory note payable to the former
stockholders of Crown and (ii) the outstanding borrowings under Crown's bank
credit agreement (see Note 2). In November 1997, the Company repaid all of the
outstanding borrowings under the Senior Credit Facility with a portion of the
proceeds from the issuance of its 10 5/8% Senior Discount Notes (as discussed
below). Upon the merger of CTC into CCI in January 1998, CCI became the primary
borrower under the Senior Credit Facility. In December 1998, the Company again
repaid all of the outstanding borrowings under the Senior Credit Facility with
a portion of the proceeds from the issuance of its 12 3/4% Senior Exchangeable
Preferred Stock (see Note 8). As of December 31, 1998, approximately
$77,570,000 of borrowings was available under the Senior Credit Facility, of
which $5,000,000 was available for letters of credit. There were no letters of
credit outstanding as of December 31, 1998.

The amount of available borrowings under the Senior Credit Facility will
decrease by $5,000,000 at the end of each calendar quarter beginning on March
31, 2001 until December 31, 2004, at which time any remaining borrowings must
be repaid. Under certain circumstances, CCI may be required to make principal
prepayments under the Senior Credit Facility in an amount equal to 50% of
excess cash flow (as defined), the net cash proceeds from certain asset sales
or the net cash proceeds from certain sales of equity or debt securities by the
Company.

The Senior Credit Facility is secured by substantially all of the assets of
CCI and the Company's pledge of the capital stock of CCI and its subsidiaries.
In addition, the Senior Credit Facility is guaranteed by the Company.
Borrowings under the Senior Credit Facility bear interest at a rate per annum,
at the Company's election, equal to the bank's prime rate plus 1.5% or a
Eurodollar interbank offered rate (LIBOR) plus 3.25% (9.25% and 8.32%,
respectively, at December 31, 1998). The interest rate margins may be reduced
by up to 2.25% (non-cumulatively) based on a financial test, determined
quarterly. As of December 31, 1998, the financial test permitted a reduction of
1.5% in the interest rate margin for prime rate borrowings and 2.25% in the
interest rate margin for LIBOR borrowings. Interest on prime rate loans is due
quarterly, while interest on LIBOR loans is due at the end of the period (from
one to three months) for which such LIBOR rate is in effect. The Senior Credit
Facility requires CCI to maintain certain financial covenants and places
restrictions on CCI's ability to, among other things, incur debt and liens, pay
dividends, make capital expenditures, dispose of assets, undertake transactions
with affiliates and make investments.

10 5/8% Senior Discount Notes due 2007 (the "Notes")
On November 25, 1997, the Company issued $251,000,000 aggregate principal
amount of the Notes for cash proceeds of $150,010,000 (net of original issue
discount). The Company used a

F-16
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

portion of the net proceeds from the sale of the Notes to (i) repay all of the
outstanding borrowings, including accrued interest thereon, under the Senior
Credit Facility; (ii) repay the promissory notes payable, including accrued
interest thereon, to the former stockholders of TEA (see Note 2); (iii) repay
certain indebtedness, including accrued interest thereon, from a prior
acquisition; and (iv) repay outstanding installment debt assumed in connection
with the Crown acquisition (see Note 2).

The Notes will not pay any interest until May 15, 2003, at which time semi-
annual interest payments will commence and become due on each May 15 and
November 15 thereafter. The maturity date of the Notes is November 15, 2007.
The Notes are net of unamortized discount of $99,407,000 and $82,901,000 at
December 31, 1997 and 1998, respectively.

The Notes are redeemable at the option of the Company, in whole or in part,
on or after November 15, 2002 at a price of 105.313% of the principal amount
plus accrued interest. The redemption price is reduced annually until November
15, 2005, after which time the Notes are redeemable at par. Prior to November
15, 2000, the Company may redeem up to 35% of the aggregate principal amount of
the Notes, at a price of 110.625% of the accreted value thereof, with the net
cash proceeds from a public offering of the Company's common stock.

The Notes are senior indebtedness of the Company; however, they are
unsecured and effectively subordinate to the liabilities of the Company's
subsidiaries, which include outstanding borrowings under the Senior Credit
Facility, the CTI Credit Facility and the CTI Bonds. The indenture governing
the Notes (the "Indenture") places restrictions on the Company's ability to,
among other things, pay dividends and make capital distributions, make
investments, incur additional debt and liens, issue additional preferred stock,
dispose of assets and undertake transactions with affiliates. As of December
31, 1998, the Company was effectively precluded from paying dividends on its
capital stock under the terms of the Indenture.

Reporting Requirements Under the Indenture (Unaudited)
The following information (as such capitalized terms are defined in the
Indenture) is presented solely as a requirement of the Indenture; such
information is not intended as an alternative measure of financial position,
operating results or cash flow from operations (as determined in accordance
with generally accepted accounting principles). Furthermore, the Company's
measure of the following information may not be comparable to similarly titled
measures of other companies.

Upon consummation of the share exchange with CTI's shareholders (see Note
2), which increased the Company's ownership interest in CTI to 80%, the Company
designated CTI as an Unrestricted Subsidiary. In addition, the net proceeds
from the Company's initial public offering of common stock (see Note 9) were
placed into a newly formed subsidiary that was also designated as an
Unrestricted Subsidiary. Prior to these transactions, the Company did not have
any Unrestricted Subsidiaries. Summarized financial information for (i) the

CTI Credit Facility
CTI has a credit agreement with a syndicate of banks (as amended, the "CTI
Credit Facility") which consists of a (Pounds)64,000,000 (approximately
$106,419,000) secured revolving line of credit. Available borrowings under the
CTI Credit Facility are generally to be used to finance capital expenditures
and for working capital and general corporate purposes. As of December 31,
1998, approximately $51,243,000 of borrowings was available under the CTI
Credit Facility.

The loan commitment under the CTI Credit Facility will be automatically
reduced to zero in three equal semi-annual installments beginning on May 31,
2001 until May 31, 2002, when the CTI Credit Facility matures. Under certain
circumstances, CTI may be required to make principle prepayments from the
proceeds of certain asset sales.

The CTI Credit Facility is secured by substantially all of CTI's assets.
Borrowings under the CTI Credit Facility bear interest at a rate per annum
equal to a Eurodollar interbank offered rate (LIBOR) plus 0.85% (approximately
6.99% at December 31, 1998). Interest is due at the end of the period (from one
to six months) for which such LIBOR rate is in effect. The CTI Credit Facility
requires CTI to maintain certain financial covenants and places restrictions on
CTI's ability to, among other things, incur debt and liens, pay dividends, make
capital expenditures, dispose of assets, undertake transactions with affiliates
and make investments.

9% Guaranteed Bonds due 2007 ("CTI Bonds")
CTI has issued (Pounds)125,000,000 (approximately $207,850,000) aggregate
principal amount of the CTI Bonds. Interest payments on the CTI Bonds are due
annually on each March 30. The maturity date of the CTI Bonds is March 30,
2007. The CTI Bonds are stated net of unamortized discount.

The CTI Bonds are redeemable, at the option of CTI, in whole or in part at
any time, at the greater of their principal amount and such a price as will
provide a gross redemption yield 0.5% per annum above the gross redemption
yield on the benchmark gilt plus, in either case, accrued and unpaid interest.
Under certain circumstances, each holder of the CTI Bonds has the right to
require CTI to repurchase all or a portion of such holder's CTI Bonds at a
price equal to 101% of their aggregate principal amount plus accrued and unpaid
interest.

The CTI Bonds are guaranteed by CTI; however, they are unsecured and
effectively subordinate to the outstanding borrowings under the CTI Credit
Facility. The trust deed governing the CTI Bonds places restrictions on CTI's
ability to, among other things, pay dividends and make capital distributions,
make investments, incur additional debt and liens, dispose of assets and
undertake transactions with affiliates.

Restricted Net Assets of Subsidiaries
Under the terms of the Senior Credit Facility, the CTI Credit Facility and
the CTI Bonds, the Company's subsidiaries are limited in the amount of
dividends which can be paid to the Company. For CCI, the amount of such
dividends is limited to (i) $6,000,000 per year until October 31, 2002, and
$33,000,000 per year thereafter, and (ii) an amount to pay income taxes
attributable to the Company's Restricted Subsidiaries. CTI is effectively
precluded from paying dividends. The restricted net assets of the Company's
subsidiaries totaled approximately $826,321,000 at December 31, 1998.

Interest Rate Swap Agreement
The interest rate swap agreement had an outstanding notional amount of
$17,925,000 at January 29, 1997 (inception) and terminated on February 24,
1999. The Company paid a fixed rate

F-20
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

of 6.28% on the notional amount and received a floating rate based on LIBOR.
This agreement effectively changed the interest rate on $17,925,000 of
borrowings under the Senior Credit Facility from a floating rate to a fixed
rate of 6.28% plus the applicable margin. The Company does not believe there is
any significant exposure to credit risk due to the creditworthiness of the
counterparty. In the event of nonperformance by the counterparty, the Company's
loss would be limited to any unfavorable interest rate differential.

6.Income Taxes

The provision for income taxes consists of the following:

respectively.

At December 31, 1998, the Company has net operating loss carryforwards of
approximately $56,000,000 which are available to offset future federal taxable
income. These loss carryforwards will expire in 2010 through 2018. The
utilization of the loss carryforwards is subject to certain limitations.

7.Minority Interests

Minority interests represent the minority stockholder's interest in CTI.

8.Redeemable Preferred Stock

Exchangeable Preferred Stock
On December 16, 1998, the Company issued 200,000 shares of its 12 3/4%
Senior Exchangeable Preferred Stock due 2010 (the "Exchangeable Preferred
Stock") at a price of $1,000 per share (the liquidation preference per share).
The net proceeds received by the Company from the sale of such shares amounted
to approximately $193,000,000 (after underwriting discounts of $7,000,000 but
before other expenses of the offering, which amounted to approximately
$8,059,000). A portion of the net proceeds was used to repay outstanding
borrowings under the Senior Credit Facility of $73,750,000, and the remaining
net proceeds are currently invested in short-term investments.

The holders of the Exchangeable Preferred Stock are entitled to receive
cumulative dividends at the rate of 12 3/4% per share, compounded quarterly on
each March 15, June 15, September 15 and

F-22
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

December 15 of each year, beginning on March 15, 1999. On or before December
15, 2003, the Company has the option to pay dividends in cash or in additional
shares of Exchangeable Preferred Stock. After December 15, 2003, dividends are
payable only in cash.

The Company is required to redeem all outstanding shares of Exchangeable
Preferred Stock on December 15, 2010 at a price equal to the liquidation
preference plus accumulated and unpaid dividends. On or after December 15,
2003, the shares are redeemable at the option of the Company, in whole or in
part, at a price of 106.375% of the liquidation preference. The redemption
price is reduced on an annual basis until December 15, 2007, at which time the
shares are redeemable at the liquidation preference. Prior to December 15,
2001, the Company may redeem up to 35% of the Exchangeable Preferred Stock, at
a price of 112.75% of the liquidation preference, with the net proceeds from
certain public equity offerings. The shares of Exchangeable Preferred Stock are
exchangeable, at the option of the Company, in whole but not in part, for 12
3/4% Senior Subordinated Exchange Debentures due 2010.

The Company's obligations with respect to the Exchangeable Preferred Stock
are subordinate to all indebtedness of the Company (including the Notes), and
are effectively subordinate to all debt and liabilities of the Company's
subsidiaries (including the Senior Credit Facility, the CTI Credit Facility and
the CTI Bonds). The certificate of designations governing the Exchangeable
Preferred Stock places restrictions on the Company's ability to, among other
things, pay dividends and make capital distributions, make investments, incur
additional debt and liens, issue additional preferred stock, dispose of assets
and undertake transactions with affiliates.

Senior Preferred Stock
In August 1997, the Company issued 292,995 shares of its Senior Convertible
Preferred Stock (the "Senior Preferred Stock") at a price of $100 per share.
The net proceeds received by the Company from the sale of such shares amounted
to approximately $29,266,000, most of which was used to pay the cash portion of
the purchase price for Crown (see Note 2). In October 1997, the Company issued
an additional 364,500 shares of its Senior Preferred Stock at a price of $100
per share. The net proceeds received by the Company from the sale of such
shares amounted to $36,450,000. This amount, along with borrowings under the
Senior Credit Facility, was used to repay the promissory note from the Crown
acquisition (see Note 2).

The holders of the Senior Preferred Stock were entitled to receive
cumulative dividends at the rate of 12.5% per share, compounded annually. At
the option of the holder, each share of Senior Preferred Stock (plus any
accrued and unpaid dividends) was convertible, at any time, into shares of the
Company's common stock at a conversion price of $7.50 (subject to adjustment in
the event of an underwritten public offering of the Company's common stock). At
the date of issuance of the Senior Preferred Stock, the Company believes that
its conversion price represented the estimated fair value of the common stock
on that date. In July 1998, all of the shares of Senior Preferred Stock were
converted into shares of common stock (see Note 9).

The purchasers of the Senior Preferred Stock were also issued warrants to
purchase an aggregate 1,314,990 shares of the Company's common stock at an
exercise price of $7.50 per share (subject to adjustment in the event of an
underwritten public offering of the Company's common stock). The warrants are
exercisable, in whole or in part, at any time until August and October of 2007.
At the date of issuance of the warrants, the Company believes that the exercise
price represented the estimated fair value of the common stock on that date. As
such, the Company has not assigned any value to the warrants in its
consolidated financial statements.

Series Preferred Stock
The holders of the Company's Series A Convertible Preferred Stock (the
"Series A Preferred Stock"), the Series B Convertible Preferred Stock (the
"Series B Preferred Stock") and the Series C Convertible Preferred Stock (the
"Series C Preferred Stock") (collectively, the "Series Preferred Stock") were
entitled to receive dividends, if and when declared, at the same rate as
dividends were declared and paid with respect to the Company's common stock.
Each of the outstanding shares of Series Preferred Stock was automatically
converted into five shares of common stock upon consummation of the Company's
initial public offering (see Note 9).

In February and April of 1997, the Company issued 3,529,832 shares of its
Series C Preferred Stock at a price of $21.00 per share. The net proceeds
received by the Company from the sale of the Series C Preferred Stock amounted
to approximately $74,024,000. A portion of this amount was used to purchase the
ownership interest in CTI (see Note 4).

9.Stockholders' Equity

Common Stock
On August 18, 1998, the Company consummated its initial public offering of
common stock at a price to the public of $13 per share (the "IPO"). The Company
sold 12,320,000 shares of its common stock and received proceeds of
$151,043,000 (after underwriting discounts of $9,117,000 but before other
expenses of the IPO, which amounted to approximately $4,116,000). The net
proceeds from the IPO are currently invested in short-term investments.

In anticipation of the IPO, the Company (i) amended and restated the 1995
Stock Option Plan to, among other things, authorize the issuance of up to
18,000,000 shares of common stock pursuant to awards made thereunder and (ii)
approved an amendment to its certificate of incorporation to increase the
number of authorized shares of common and preferred stock to 690,000,000 shares
and 10,000,000 shares, respectively, and to effect a five-for-one stock split
for the shares of common stock then outstanding. The effect of the stock split
has been presented retroactively in the Company's consolidated financial
statements for all periods presented.

In July 1998, all of the holders of the Company's Senior Convertible
Preferred Stock converted such shares into an aggregate of 9,629,200 shares of
the Company's common stock. Upon consummation of the IPO, all of the holders of
the Company's then-existing shares of Class A Common Stock, Class B Common
Stock, Series A Convertible Preferred Stock, Series B Convertible Preferred
Stock and Series C Convertible Preferred Stock converted such shares into an
aggregate of 39,842,290 shares of the Company's common stock.

In March 1997, the Company repurchased, and subsequently retired, 814,790
shares of its common stock from a member of the Company's Board of Directors at
a cost of approximately $3,422,000. Of this amount, $1,311,000 was recorded as
compensation cost and is included in corporate development expense on the
Company's consolidated statement of operations. In August 1998, the Company
repurchased, and subsequently retired, 141,070 shares of its common stock from
a former employee at a cost of approximately $883,000.

F-24
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
Class A Common Stock
Upon consummation of the share exchange agreement with CTI's shareholders
(see Note 2), an affiliate of CTI's remaining minority shareholder received all
of the currently outstanding shares of the Company's Class A Common Stock. Each
share of Class A Common Stock is convertible, at the option of its holder at
any time, into one share of Common Stock. The holder of the Class A Common
Stock is entitled to one vote per share on all matters presented to a vote of
the Company's shareholders, except with respect to the election of directors.
The holder of the Class A Common Stock, voting as a separate class, has the
right to elect up to two members of the Company's Board of Directors. The
shares of Class A Common Stock also provide certain governance and anti-
dilutive rights.

Compensation Charges Related to Stock Option Grants
During the period from April 24, 1998 through July 15, 1998, the Company
granted options to employees and executives for the purchase of 3,236,980
shares of its common stock at an exercise price of $7.50 per share. Of such
options, options for 1,810,730 shares vested upon consummation of the IPO and
the remaining options for 1,426,250 shares will vest at 20% per year over five
years, beginning one year from the date of grant. In addition, the Company has
assigned its right to repurchase shares of its common stock from a stockholder
(at a price of $6.26 per share) to two individuals (including a newly-elected
director) with respect to 100,000 of such shares. Since the granting of these
options and the assignment of these rights to repurchase shares occurred
subsequent to the date of the share exchange agreement with CTI's shareholders
and at prices substantially below the price to the public in the IPO, the
Company has recorded a non-cash compensation charge related to these options
and shares based upon the difference between the respective exercise and
purchase prices and the price to the public in the IPO. Such compensation
charge will total approximately $18.4 million, of which approximately $10.6
million was recognized upon consummation of the IPO (for such options and
shares which vested upon consummation of the IPO), and the remaining $7.8
million is being recognized over five years (approximately $1.6 million per
year) through the second quarter of 2003. An additional $1.6 million in non-
cash compensation charges will be recognized through the third quarter of 2001
for stock options issued to certain members of CTI's management prior to the
consummation of the share exchange.

Stock Options
In 1995, the Company adopted the Crown Castle International Corp. 1995
Stock Option Plan (as amended, the "1995 Stock Option Plan"). Up to 18,000,000
shares of the Company's common stock were reserved for awards granted to
certain employees, consultants and non-employee directors of the Company and
its subsidiaries or affiliates. These options generally vest over periods of up
to five years from the date of grant (as determined by the Company's Board of
Directors) and have a maximum term of ten years from the date of grant.

Upon consummation of the share exchange agreement with CTI's shareholders
(see Note 2), the Company adopted each of the various CTI stock option plans.
All outstanding options to purchase shares of CTI under such plans have been
converted into options to purchase shares of the Company's common stock. Up to
4,392,451 shares of the Company's common stock were reserved for awards granted
under the CTI plans, and these options generally vest over periods of up to
three years from the date of grant.

The weighted-average fair value of options granted during the years ended
December 31, 1996, 1997 and 1998 was $0.50, $1.30 and $4.54, respectively. The
fair value of each option was estimated on the date of grant using the Black-
Scholes option-pricing model and the following weighted-average assumptions
about the options (the minimum value method was used prior to the IPO):

<TABLE>

</TABLE>

The exercise prices for options granted during the years ended December
31, 1996 and 1997 were equal to or in excess of the estimated fair value of
the Company's common stock at the date of grant. As such, no compensation cost
was recognized for stock options during those years (see Note 1 and
"Compensation Charges Related to Stock Option Grants"). If compensation cost
had been recognized for stock options based on their fair value at the date of
grant, the Company's pro forma net loss for the years ended December 31, 1996,
1997 and 1998 would have been $973,000 ($0.28 per share), $12,586,000 ($2.37
per share) and $75,660,000 ($1.91 per share), respectively. The pro forma
effect of stock options on the Company's net loss for those years may not be
representative of the pro forma effect for future years due to the impact of
vesting and potential future awards.

10.Employee Benefit Plans

The Company and its subsidiaries have various defined contribution savings
plans covering substantially all employees. Depending on the plan, employees
may elect to contribute up to 20% of their eligible compensation. Certain of
the plans provide for partial matching of such contributions. The cost to the
Company for these plans amounted to $98,000 and $197,000 for the years ended
December 31, 1997 and 1998, respectively.

CTI has a defined benefit plan which covers all of its employees hired on
or before March 1, 1997. Employees hired after that date are not eligible to
participate in this plan. The net periodic pension cost attributable to this
plan for the four months ended December 31, 1998 was $1,115,000. As of
December 31, 1998, (i) the accumulated benefit obligation under this plan
amounted to $13,635,000 (all of which was vested); (ii) the projected benefit
obligation amounted to $15,298,000; (iii) the fair value of the plan's assets
amounted to $15,848,000; and (iv) the prepaid pension cost attributable to
this plan amounted to $1,704,000.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

11. Related Party Transactions

The Company leases office space in a building formerly owned by its Chief
Executive Officer. Lease payments for such office space amounted to $50,000 and
$130,000 for the years ended December 31, 1996 and 1997, respectively.

Included in other receivables at December 31, 1997 and 1998 are amounts due
from employees of the Company totaling $499,000 and $368,000, respectively.

12. Commitments and Contingencies

At December 31, 1998, minimum rental commitments under operating leases are
as follows: years ending December 31, 1999--$19,721,000; 2000--$19,456,000;
2001--$19,298,000; 2002--$19,293,000; 2003--$18,996,000; thereafter--
$112,848,000. Rental expense for operating leases was $277,000, $1,712,000 and
$9,620,000 for the years ended December 31, 1996, 1997 and 1998, respectively.

The Company is involved in various claims, lawsuits and proceedings arising
in the ordinary course of business. While there are uncertainties inherent in
the ultimate outcome of such matters and it is impossible to presently
determine the ultimate costs that may be incurred, management believes the
resolution of such uncertainties and the incurrence of such costs should not
have a material adverse effect on the Company's consolidated financial position
or results of operations.

13. Operating Segments and Concentrations of Credit Risk

Operating Segments
The Company's reportable operating segments for 1998 are (i) the domestic
operations of CCI and (ii) the United Kingdom operations of CTI. Financial
results for the Company are reported to management and the Board of Directors
in this manner, and much of the Company's current debt financing is structured
along these geographic lines. In addition, the Company's financial performance
is evaluated by outside securities analysts based on these operating segments.
See Note 1 for a description of the primary revenue sources from these two
segments.

As discussed in Note 2, CTI's results of operations are included in the
Company's consolidated financial statements beginning in 1998. Prior to that
time, the domestic operations of CCI represented the Company's only reportable
segment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The measurement of profit or loss currently used to evaluate the results of
operations for the Company and its operating segments is earnings before
interest, taxes, depreciation and amortization ("EBITDA"). The Company defines
EBITDA as operating income (loss) plus depreciation and amortization and non-
cash compensation charges. EBITDA is not intended as an alternative measure of
operating results or cash flow from operations (as determined in accordance
with generally accepted accounting principles), and the Company's measure of
EBITDA may not be comparable to similarly titled measures of other companies.
There are no significant revenues resulting from transactions between the
Company's operating segments. Total assets for the Company's operating segments
are determined based on the separate consolidated balance sheets for CCI and
CTI. The results of operations and financial position for CTI reflect
appropriate adjustments for their presentation in accordance with generally
accepted accounting principles in the United States. The financial results for
the Company's operating segments are as follows:

Major Customers
For the years ended December 31, 1996, 1997 and 1998, CCI had revenues
from a single customer amounting to $2,634,000, $5,998,000 and
$14,168,000, respectively. For the year ended December 31, 1998,
consolidated net revenues includes $33,044,000 from a single customer of
CTI.

Concentrations of Credit Risk
Financial instruments that potentially subject the Company to
concentrations of credit risk are primarily cash and cash equivalents and
trade receivables. The Company mitigates its risk with respect to cash and
cash equivalents by maintaining such deposits at high credit quality
financial institutions and monitoring the credit ratings of those
institutions.

The Company derives the largest portion of its revenues from customers
in the wireless telecommunications industry. In addition, the Company has
concentrations of operations in certain geographic areas (primarily the
United Kingdom, Pennsylvania, Texas, New Mexico, Arizona and Puerto Rico).
The Company mitigates its concentrations of credit risk with respect to
trade receivables by actively monitoring the creditworthiness of its
customers. Historically, the Company has not incurred any significant
credit related losses.

15. Subsequent Events (Unaudited)

BellSouth Mobility Inc. and BellSouth Telecommunications Inc. ("BellSouth")
In March 1999, the Company entered into an agreement with BellSouth to
acquire the operating rights for approximately 1,850 of their towers. The
transaction is structured as a lease agreement and will be treated as a sale of
the towers for tax purposes. The Company will pay BellSouth consideration of
$610,000,000, consisting of $430,000,000 in cash and $180,000,000 in shares of
its common stock. The Company will account for this transaction as a purchase
of tower assets. The transaction is expected to close over a period of up to
eight months beginning in the second quarter of 1999. Upon entering into the
agreement, the Company placed $50,000,000 into an escrow account. In order to
fund this escrow deposit, the Company borrowed $45,000,000 under the Senior
Credit Facility.

Powertel, Inc. ("Powertel")
In March 1999, the Company entered into an agreement with Powertel to
purchase approximately 650 of their towers and related assets. The purchase
price for these towers will be $275,000,000 in cash. The Company will account
for this transaction as an acquisition using the purchase method. Upon entering
into the agreement, the Company placed $50,000,000 into an escrow account. The
Company funded this escrow deposit with borrowings under a $100,000,000 loan
agreement provided by a syndicate of investment banks. The remaining
$50,000,000 of borrowings under this loan agreement were used to repay the
amount drawn under the Senior Credit Facility in connection with the BellSouth
escrow deposit.

Proposed Securities Offerings
The Company intends to offer shares of its common stock and debt securities
in concurrent underwritten public offerings. The proceeds from such offerings
would be used to repay amounts drawn under the loan agreement in connection
with the BellSouth and Powertel transactions, and to pay the remaining purchase
price for such transactions. Any securities will only be offered by means of a
prospectus forming a part of a registration statement filed with the Securities
and Exchange Commission. There can be no assurance that such securities
offerings can be successfully completed.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors
of Castle Transmission Services (Holdings) Ltd:

We have audited the accompanying balance sheet of the BBC Home Service
Transmission business ("Home Service") at March 31, 1996 and the consolidated
balance sheets of Castle Transmission Services (Holdings) Ltd and its
subsidiaries ("Castle Transmission") at March 31, 1997 and December 31, 1997
and the profit and loss accounts, cash flow statements and reconciliations of
movements in corporate funding for Home Service for the year ended March 31,
1996 and the period from April 1, 1996 to February 27, 1997 and the related
consolidated profit and loss accounts, cash flow statements and reconciliations
of movements in shareholders' funds for Castle Transmission for the period from
February 28, 1997 to March 31, 1997 and the period from April 1, 1997 to
December 31, 1997. These financial statements are the responsibility of Castle
Transmission's and Home Service's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards in the United Kingdom, which do not differ in any material respect
from generally accepted auditing standards in the United States. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free from material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Home Service at March 31,
1996 and the consolidated financial position of Castle Transmission at March
31, 1997 and December 31, 1997 and the results of operations and cash flows of
Home Service for the year ended March 31, 1996 and for the period from April 1,
1996 to February 27, 1997 and of Castle Transmission for the period from
February 28, 1997 to March 31, 1997 and for the period from April 1, 1997 to
December 31, 1997 in conformity with generally accepted accounting principles
in the United Kingdom.

Generally accepted accounting principles in the United Kingdom vary in
certain respects from generally accepted accounting principles in the United
States. Application of generally accepted accounting principles in the United
States would have affected results of operations for the year ended March 31,
1996 and the period from April 1, 1996 to February 27, 1997 for Home Service
and the period from February 28, 1997 to March 31, 1997 and from April 1, 1997
to December 31, 1997 for Castle Transmission and shareholders' equity at
March 31, 1996 for Home Service and at March 31, 1997 and December 31, 1997 for
Castle Transmission to the extent summarised in Note 27 to these financial
statements.

Service Transmission business of the British Broadcasting Corporation ("BBC")
which was the predecessor business.

These consolidated financial statements have been prepared in accordance
with generally accepted accounting principles ("GAAP") applicable in the United
Kingdom (UK) and comply with the financial reporting standards of the Institute
of Chartered Accountants in England and Wales. A summary of the differences
between UK GAAP and United States (US) GAAP as applicable to Castle
Transmission is set out in Note 27.

Castle Transmission Services (Holdings) Ltd (the "Company") was
incorporated on August 27, 1996 and did not trade in the period to February 27,
1997. CTI was incorporated by the BBC on May 9, 1996 and did not trade in the
period to February 27, 1997. On February 27, 1997, the assets and liabilities
of Home Service were transferred to CTI. On February 28, 1997 CTI was acquired
by the Company. During the period between August 27, 1996 and February 27, 1997
Castle Transmission did not trade and received no income and incurred no
expenditure. Accordingly the first consolidated profit and loss account for
Castle Transmission represents the trading of Castle Transmission for the
period from February 28, 1997 to March 31, 1997. CTF was incorporated
April 9, 1997.

The financial statements for the year ended March 31, 1996 and the period
from April 1, 1996 to February 27, 1997 represent the profit and loss accounts,
balance sheet, cash flow statements and reconciliations of movements in
corporate funding of Home Service. They have been prepared from the separate
financial records and management accounts of Home Service.

Home Service was charged a management fee by the BBC representing an
allocation of certain costs including pension, information technology,
occupancy and other administration costs which were incurred centrally by the
BBC but which were directly attributable to Home Service. Management believes
such allocation is reasonable. Such costs are based on the pension arrangement
and the cost structure of the BBC and are not necessarily representative of
such costs of Castle Transmission under separate ownership.

Home Service did not incur any costs in relation to financing as necessary
funding was provided from the BBC through the corporate funding account. No
interest is charged by the BBC on such funds because there is no debt at BBC
which is attributable to Home Service.

Home Service was not a separate legal entity and therefore was not directly
subject to taxation on its results. The BBC is a not-for-profit organisation
and is not subject to taxation except to the extent of activities undertaken
with the objective of making a profit, including all external activities
(principally site sharing and commercial projects). The tax charge attributable
to Home Service has been calculated as if Home Service were under separate
ownership since April 1, 1994 and as if all of its results of operations were
subject to normal taxation.

Redundancy costs were incurred by the BBC which related to Home Service
staff. The redundancy costs amounted to (Pounds)1.1m in 1996 and (Pounds)0.6m
in the period from April 1, 1996 to

F-38

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

February 27, 1997. The redundancy programmes were controlled by the BBC and the
costs were not recharged to Home Service. No adjustment has been made in the
Home Service financial statements for these costs because any costs incurred
would have been reflected in the cost base of Home Service, and as described in
note 25 would have been off-set by an increase in turnover from the BBC.

The consolidated financial statements for the two months ended February 27,
1997 and as of and for the eight months ended August 31, 1998 are unaudited;
however, in the opinion of all the directors, all adjustments (consisting of
normal recurring adjustments) necessary for a fair presentation have been made.
Accounting measurements at interim dates inherently involve greater reliance on
estimates than at year end. Operating results for the eight month period ended
August 31, 1998 are not necessarily indicative of the results that may be
expected for the year ending December 31, 1998.

2 Accounting policies

The following accounting policies have been applied consistently in dealing
with items which are considered material in relation to the financial
statements of Home Service and the consolidated financial statements of Castle
Transmission.

Basis of consolidation

The consolidated financial statements include the financial statements of
the Company and its subsidiaries made up to March 31, 1997 and December 31,
1997 after elimination of all significant inter-company accounts and
transactions. The acquisition method of accounting has been adopted. Under this
method, the results of subsidiaries acquired or disposed of in the period are
included in the consolidated profit and loss account from the date of
acquisition or up to the date of disposal.

Goodwill

Purchased goodwill on acquisitions (representing the excess of the fair
value of the consideration given over the fair value of the separable net
assets acquired) is capitalised and amortised over 20 years, the period over
which the Directors consider that the Group will derive economic benefits.

Tangible fixed assets and depreciation

Depreciation is provided to write off the cost or valuation less the
estimated residual value of tangible fixed assets by equal instalments over
their estimated useful economic lives as follows:

Land and buildings

Other plant and machinery.................. 3-10 years 3-10 years
Computer equipment......................... 5 years 5 years
Motor vehicles............................. -- 3 years
</TABLE>

Strategic spares, which comprise those spares that are vital to the
operation of the transmission system, are included in the capitalised value of
the asset to which they relate and are depreciated over the life of the asset.

Assets under construction are included within fixed assets. The associated
labour costs are capitalised using a predetermined labour rate, and any over or
under recoveries are recognised in the profit and loss account in the period in
which they arise.

Foreign currencies

Transactions in foreign currencies are translated at the rate of exchange
ruling at the date of the transaction. Monetary assets and liabilities, to the
extent that they are denominated in foreign currency, are retranslated at the
rate of exchange ruling at the balance sheet date and gains or losses are
included in the profit and loss account.

Leases

Where the Company enters into a lease which entails taking substantially
all the risks and rewards of ownership of an asset, the lease is treated as a
"finance lease'. The asset is recorded in the balance sheet as a tangible fixed
asset and is depreciated over its useful life or term of the lease, whichever
is shorter. Future instalments under such leases, net of finance charges, are
included within creditors. Rentals payable are apportioned between the finance
element, which is charged to the profit and loss account, and the capital
element which reduces the outstanding obligation for future instalments.

Operating lease rentals are charged to the profit and loss account on a
straight line basis over the period of the lease.

Pensions

The pension costs charged in the period include costs incurred, at the
agreed employer's contribution rate. See note 20 for further details.

Stocks

Stocks held are general maintenance spares and manufacturing stocks. Stocks
are stated at the lower of weighted average cost and net realisable value.

Work in progress

For individual projects, the fees on account and project costs are
recorded in work in progress. When a project is complete, the project balances
are transferred to turnover and cost of

F-40

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

sales as appropriate, and the net profit is recognised. Where the payments on
account are in excess of project costs, these are recorded as payments on
account.

Provision is made for any losses as soon as they are foreseen.

Taxation

The charge for taxation is based on the result for the period and takes
into account taxation deferred because of timing differences between the
treatment of certain items for taxation and accounting purposes. Provision is
made for deferred tax only to the extent that it is probable that an actual
liability will crystallise.

Turnover

Turnover represents the amounts (excluding value added tax) derived from
the provision of transmission and maintenance contracts, site sharing
arrangements and commercial projects. Revenue is recognised on the basis of
contracts or as services are provided to customers.

Issue costs

Costs incurred in raising funds are deducted from the amount raised and
amortised over the life of the debt facility on a constant yield basis.

8 Taxation

Home Service

There is no tax charge in respect of the results of Home Service for the
year ended March 31, 1996 or for the period from April 1, 1996 to February 27,
1997. As a separate legal entity subject to normal taxation, Home Service would
have capital allowances available as discussed below which would result in
taxable losses for all periods. Deferred tax assets have not been recognised on
such tax losses as management has concluded that it is not likely that the
deferred tax asset would be realised.

Castle Transmission

There is no tax charge in respect of the period from February 28, 1997 to
March 31, 1997 and April 1, 1997 to December 31, 1997. Based on an agreement
with the Inland Revenue Service, Castle Transmission will have capital
allowances available on capital expenditure incurred by Home Service and the
BBC prior to the acquisition of approximately (Pounds)179 million. The
accelerated tax deductions associated with such capital allowances result in a
taxable loss for both periods. Deferred tax assets have not been recognised on
such tax losses as management has concluded that it is not likely that the
deferred tax asset would be realised based on the limited operating history of
Castle Transmission.

On May 21, 1997, CTF issued and Castle Transmission guaranteed,
(Pounds)125,000,000 9 percent Guaranteed Bonds due 2007 (the "Guaranteed
Bonds"). The Guaranteed Bonds are redeemable at their principal amount, unless
previously redeemed or purchased and cancelled, on March 30, 2007.

The Guaranteed Bonds may be redeemed in whole but not in part, at the
option of CTF, at their principal amount plus accrued interest if, as a result
of certain changes in the laws and regulations of the United Kingdom, CTF or
Castle Transmission becomes obliged to pay additional amounts.

The Guaranteed Bonds may be redeemed in whole or in part, at the option of
CTF, at any time at the higher of their principal amount and such a price as
will provide a gross redemption yield 0.50 percent per annum above the gross
redemption yield on the benchmark gilt plus (in either case) accrued interest.

Bondholders may, in certain circumstances including but not limited to a
change in control of CTF, or the early termination of the agreement between CTI
and the BBC relating to the domestic analogue transmission of radio and
television programmes by CTI, require the Guaranteed Bonds to be redeemed at
101 percent of their principal amount plus accrued interest.

The Guaranteed Bonds were issued at an issue price of 99.161 percent. The
Guaranteed Bonds are shown net of unamortised discount and issue costs.
Interest accrues from the date of issue and is payable in arrears on March 30
each year commencing March 30, 1998.

On February 28, 1997 the Group entered into term and revolving loan
facilities with a syndicate of banks. There are three facilities. Facility A
and Facility B are (Pounds)122,500,000 and (Pounds)35,000,000 term loan
facilities. Facility A is repayable in instalments, the last of which is due in
June 2004, and Facility B is repayable in two instalments in December 2004 and
June 2005. These facilities were made available to finance the amount owed to
the BBC on the acquisition of the Home Service transmission business and were
drawn down in full on February 28, 1997.

The third facility, Facility C, is a (Pounds)5,000,000 revolving loan
facility maturing in June 2005 under which advances are to be made to the Group
to finance its working capital requirements and for general corporate purposes.
This facility was undrawn at March 31, 1997.

Borrowings under the facilities are secured by fixed and floating charges
over substantially all of the assets and undertakings of the Group and bear
interest at 2.25 percent above LIBOR for Facility B and between 0.875 percent
and 1.75 percent above LIBOR (depending on the annualised debt coverage and the
outstanding percentage of the facilities) for Facilities A and C.

The net proceeds of the Guaranteed Bonds were used to repay substantially
all of the amounts outstanding under Facilities A, B and C. The remaining
balance of Facilities A, B and C was replaced by a (Pounds)64,000,000 revolving
loan facility maturing in May 2002 (the "New Facility"), under which advances
will be made to CTI to finance its working capital requirements and finance
capital expenditures in respect of Digital Terrestrial Television.

Borrowings under the New Facility are secured by fixed and floating charges
over substantially all of the assets and undertakings of Castle Transmission
and bear interest at LIBOR plus the applicable margin plus cost rate.

Included within bank loans and overdrafts is an amount of (Pounds)3,142,000
at March 31, 1997 and (Pounds)1,055,000 at December 31, 1997 representing
finance costs deferred to future accounting periods in accordance with FRS4. As
a result of the issuance of the Guaranteed Bonds and the New Facility, the
remaining deferred financing costs of (Pounds)1,930,000, relating to Facilities
A, B and C were charged to the profit and loss account during the period from
April 1, 1997 to December 31, 1997.

Home Service did not make any provisions for liabilities and charges. On
the acquisition by Castle Transmission, a provision was established for costs
associated with the split of the BBC transmission business between Home Service
and World Service comprising redundancy costs and costs relating to the
relocation and reorganisation of shared sites. No payments or additional
provisions were made in the one month period and the balance on acquisition and
at March 31, 1997 was (Pounds)1,723,000.

(Pounds)1,250,000 in respect of a contingent liability for wind loading fees
that existed at February 27, 1997. See notes 18 and 24 for further details.

A further provision of (Pounds)417,000, in respect of these wind loading

On incorporation the Company had an authorised share capital of 100
Ordinary Shares of (Pounds)1 each of which 1 share was allotted, called up and
fully paid.

On January 23, 1997, the 100 issued and unissued Ordinary Shares of
(Pounds)1 each were subdivided into Ordinary Shares of 1 pence each and the
authorised share capital of the Company was increased to (Pounds)114,772,900 by
the creation of 11,467,290 additional Ordinary Shares of 1 pence each and by
the creation of 11,465,812,710 Redeemable Preference Shares of 1 pence each.

On February 28, 1997 the Company issued for cash 10,234,690 Ordinary Shares
of 1 pence each at par and 10,224,555,210 Redeemable Preference Shares of 1
pence each at par.

On September 19, 1997 a further 55,000 Ordinary Shares of 1 pence each and
54,945,000 Redeemable Preference Shares of 1 pence each were issued at par for
cash. These shares were issued to certain members of the management team.
Management believes that this sale price reflects the fair value of the shares
at that date.

The Redeemable Preference Shares are redeemable on December 31, 2050. The
Company may also redeem any number of Redeemable Preference Shares at any time
by giving at least two business days' notice in writing to the holders. In
addition, the Company shall redeem in full all the Redeemable Preference Shares
on or before the earlier or any listing or sale of 87.5 percent or more of the
issued share capital. No premium is payable on redemption.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The holders of the Redeemable Preference Shares are entitled to receive a
dividend in respect of periods from January 1, 2004 at a rate of 5 percent per
annum. Dividends shall accrue on a daily basis and shall, unless the Company is
prohibited from paying dividends by the Companies Act 1985 or is not permitted
by any financing agreement to which it is a party to pay such dividend, become
a debt due from and payable to the holders of the Redeemable Preference Shares
on January 1 of each year beginning January 1, 2005.

In accordance with FRS4: Capital Instruments, a finance cost has been
calculated to result in a constant rate of return over the period and carrying
amount for these Redeemable Preference Shares and has been included in the
profit and loss account as an appropriation.

On a winding up of the Company, the holders of the Redeemable Preference
Shares would be entitled, in priority to any payment to the holders of the
Ordinary Shares, to receive an amount equal to the nominal amount paid up on
each Redeemable Preference Share together with all arrears and accruals of the
preferential dividend payable thereon, whether or not such dividend has become
due and payable.

The holders of the Redeemable Preference Shares have no right to vote at
any general meeting of the Company.

At December 31, 1997 two of the shareholders held share warrants which
entitled them to a maximum of 772,500 Ordinary Shares and 771,727,500
Redeemable Preference Shares issued at par. These are subject to adjustment in
accordance with the conditions set out in the warrant instrument which relate
to any reorganisation of the Company's share capital. The rights under the
share warrants can be exercised by giving 7 days' notice to the Company. The
rights lapse on the earliest of the following dates: the date of a listing of
any part of the share capital on the Official List of the London Stock Exchange
or any other stock exchange; the date of any sale of 85 percent or more of the
issued share capital of the Company; the date on which the Company goes into
liquidation; and February 28, 2007.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

As the two transactions were enacted for the purpose of the sale and
purchase of Home Service, a provisional fair value exercise was performed by
CTI on the acquisition of the trade and net assets of Home Service on 27
February 1997, giving rise to acquisition goodwill of (Pounds)39.6 million.

The fair value exercise was only provisional at March 31, 1997 as the
elapsed time had not been sufficient to form a final judgement on the fair
value adjustments. The fair value exercise has now been finalised and as a
result goodwill has been increased by (Pounds)1.2 million. See note 24.

The consideration paid for the acquisition of the shares of CTI by the
Company amounted to (Pounds)45 million plus fees of (Pounds)7.5 million.
(Pounds)7.2 million had been paid or accrued at March 31, 1997, which gave rise
to additional goodwill of (Pounds)7.5 million.

In addition, the BBC was paid (Pounds)199 million by CTI as a repayment of
the loan made by the BBC on the transfer of the assets and liabilities of Home
Service. The total consideration paid by the Group amounted to (Pounds)244
million (excluding fees), which resulted in total goodwill in the Consolidated
Financial Statements of (Pounds)48 million. This goodwill has been capitalised
and will be written off over 20 years, the period over which the Directors
consider that the Group will derive economic benefits.

(a) Capital commitments at the end of the financial period for which no
provision has been made, were as follows:

20 Pension scheme

Home Service

Home Service participated in a multi-employer pension scheme operated by
the BBC. The scheme is a defined benefit scheme whereby retirement benefits are
based on the employees' final

F-52
<PAGE>

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

remuneration and length of service and is funded through a separate trustee
administered scheme. Contributions to the scheme are based on pension costs for
all members of the scheme across the BBC and are made in accordance with the
recommendations of independent actuaries who value the scheme at regular
intervals, usually triennially. Pension scheme assets are not apportioned
between different parts of the BBC.

The pension rate charged to Home Service was 4.5 percent for the year ended
March 31, 1996 and for the period from April 1, 1996 to February 27, 1997. This
charge took into account the surplus shown by the last actuarial valuation of
the BBC scheme. Amounts charged were as follows: (Pounds)521,000 in 1996 and
(Pounds)491,000 in the period from April 1, 1996 to February 27, 1997.

Castle Transmission

The pension charge is not comparable between Home Service and Castle
Transmission due to the former having a reduced charge as a result of the
surplus in the BBC Pension scheme.

Under the terms of the sale agreement Castle Transmission was temporarily
participating in the BBC Pension scheme until July 31, 1997. From August 1,
1997 the Group was committed under the sale agreement to establish its own
pension scheme.

In respect of past service benefits, members were able to choose between
transferring past service benefits to the Group scheme or leaving them in the
BBC Pension scheme. To the extent that past service benefits were transferred,
the BBC Pension scheme made a full transfer payment to the Group scheme
calculated in accordance with the actuarial basis as set out in the sale
agreement.

The pension charge for the period from February 28, 1997 to March 31, 1997
included in the accounts represented contributions payable to the BBC Pension
scheme and amounted to (Pounds)156,000. Contributions are calculated at the
employers' contribution rate of 17.7 per cent of pensionable salary. The
contribution rate has been determined by a qualified actuary and is specified
in the sale agreement.

At August 1, 1997 Castle Transmission established its own pension scheme.
This is a defined benefit scheme and assets were transferred from the BBC
Pension scheme to the extent that members chose to transfer past benefits. From
August 1, the Castle Transmission Pension Scheme will be liable in respect of
future pension benefits. The pension charge for the period from April 1, 1997
to December 31, 1997 was (Pounds)1,490,000.

There were no outstanding or prepaid contributions at either the beginning
or end of the financial periods.

The Group also established a defined contribution scheme which will have a
backdated start date of August 1, 1997. This scheme will be open to employees
joining the Group after March 1, 1997. The defined benefit scheme will not be
open to these employees. The pensionable charge for the period from April 1,
1997 to December 31, 1997 represents contributions under this scheme amounting
to (Pounds)nil.

The total consideration paid by Castle Transmission included the assumption

Fair value adjustments

The fair value adjustments result from the completion of the fair value
exercise performed by CTI on the acquisition of Home Service and the under
accrual of fees by the Company, in relation to the acquisition of CTI, at March
31, 1997. The (Pounds)1,237,000 increase in goodwill relates predominantly to
the provision of (Pounds)1,250,000 in respect of a dispute over wind loading
fees. This dispute was an existing contingent liability at the date of
acquisition and consequently provision has been made against the fair value of
the assets and liabilities of Home Service at February 27, 1998.

25 Related party disclosures

Home Service

Throughout the year ended March, 31 1996 and the period from April 1, 1996
to February 27, 1997, Home Service entered into a number of transactions with
other parts of the BBC. Substantially all of these transactions are exempt from
the disclosure provisions of FRS 8 "Related Party Disclosures" as they have
been undertaken between different parts of the BBC, and are eliminated in the
consolidated accounts of the BBC. However, brief details of the nature of these
transactions are set out below.

The majority of Home Service's income arises from trading with other parts
of the BBC. Prices are set at BBC group level on the basis of cost budgets
prepared by Home Service. The aggregate value of such sales in each of the
years covered by the combined financial statements is given in Note 3.

Administrative costs include expenses re-charged to Home Service by the
BBC. These re-charges related to costs incurred centrally in respect of
pension, information technology, occupancy and other administration costs.
These charges amounted to (Pounds)5.8 million in 1996 and (Pounds)1.2 million
in the period between April 1, 1996 and February 27, 1997. The reduced charge
for the period to February 27, 1997 is a result of more functions being carried
out by employees of Home Service in preparation for the change to a stand alone
entity.

In addition, re-charges were also made for distribution costs relating to
telecommunication links between the BBC and the transmitting stations and these
were then internally re-charged to other parts of the BBC. The charges amounted
to (Pounds)5.6 million in 1996 and (Pounds)6.4 million in the period between
April 1, 1996 and February 27, 1997.

Ongoing BBC relationship

At the time of the acquisition of Home Service, Castle Transmission entered
into a ten year transmission contract with the BBC for the provision of
domestic terrestrial analogue television and radio transmission services
expiring on March 31, 2007. Thereafter, the contract continues until terminated
by twelve months notice by either party on March 31 in any contract year from
and including March 31, 2007. It may also be terminated early if certain
conditions are met.

The contract provides for charges of approximately (Pounds)46 million to be
payable by the BBC to Castle Transmission for the year to March 31, 1998.
Castle Transmission's charges for subsequent years of the contract are largely
determined by a formula which escalates the majority of the charges by a factor
which

F-58
<PAGE>

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

is 1% below the rate of increase in the Retail Price Index over the previous
calendar year. Those elements of the charges which are subject to the
escalation formula for the contract year commencing April 1, 1998 amount to
approximately (Pounds)46 million.

26 Post balance sheet events

On January 23, 1998, the Board of Directors adopted: (i) the All Employee
Share Option Scheme; (ii) the Management Share Option Scheme; and (iii)
individual share option arrangements for certain directors of the Company.

The All Employee Share Option Scheme provides for an unlimited number of
shares to be granted to all employees of the Company. The Board may select any
number of individuals to apply for the grant of an option. Not later than
thirty days following the date by which an application must be made, the Board
may grant to each applicant the number of options specified in his application.
These options may be exercised at the earliest of the third anniversary of the
date of grant, in the event of a flotation or in the event of a take-over,
reconstruction, liquidation or option exchange as set out in the Scheme rules.
For options granted under this scheme the option price and the number of shares
will not change during the life of the option.

Under the terms of the Management Share Option Scheme and the individual
share option arrangements, share options may be granted to employees or
directors of the Company as determined by the Board of Directors up to a
maximum of 460,000 Ordinary Shares and 459,540,000 Redeemable Preference
Shares. Options will vest over periods of up to four years and have a maximum
term of up to nine years. For options over 223,333 Ordinary Shares and
223,110,000 Redeemable Preference Shares, the option price and the number of
shares will not change during the life of the option. The remaining options are
subject to certain performance criteria.

On January 23, 1998 and January 30, 1998 the Company granted options to
purchase an aggregate of 460,000 Ordinary Shares and 459,540,000 Redeemable
Preference Shares under the terms of the individual share option arrangements
and the Management Share Option Scheme, respectively. The weighted average
price for such options is 1.16 pence for Ordinary Shares and 1.16 pence for
Redeemable Preference Shares. The weighted average vesting period for such
options is 1.13 years. Any accounting charge resulting from a difference
between the fair value of the rights to the shares at the date of grant and the
amount of consideration to be paid for the shares will be charged to the profit
and loss account in the year to December 31, 1998 and subsequent years
according to the vesting provisions of the arrangements. Where the options are
subject to performance criteria, the amount initially recognised will be based
on a reasonable expectation of the extent to which these criteria will be met
and will be subject to subsequent adjustments as necessary to deal with changes
in the probability of performance criteria being met.

Update of post balance sheet events (Unaudited)

On March 23, 1998, the Company granted options to purchase an aggregate of
40,750 Ordinary Shares and 40,709,250 Redeemable Preference Shares under the
terms of the All Employee Share Option Scheme. The price for such options is
1.00 pence for both Ordinary Shares and Redeemable Preference Shares. The
vesting period for such options is three years.

The accounting charge related to all share options included within the
unaudited consolidated financial statements for the eight months ended August
31, 1998 is (Pounds)2,330,000.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

On April 23, 1998, the Board of Directors adopted share option arrangements
for certain individuals. On that same date, the Company granted options to
purchase 60,000 Ordinary Shares and 59,940,000 Redeemable Preference Shares
under the terms of such share option arrangements. These options will vest over
a period of four years and have a maximum term of six years. The weighted
average price of such options is 1.75 pence for both Ordinary Shares and
Redeemable Preference Shares. The weighted average vesting period for such
options is two years.

On July 1, 1998 and July 15, 1998, CCIC granted options to purchase 59,932
ordinary shares in CCIC to employees of CTI under terms of individual share
option arrangements. The weighted average price for such options is $37.54.
These options vested on August 18, 1998. The accounting charge related to these
options included in the unaudited consolidated financial statements for the
eight months ended August 31, 1998 is (Pounds)978,000.

On July 15, 1998, the Board of Directors of the Company resolved that the
Management Share Option Scheme would not be subject to any performance criteria
and would vest on a time basis only.

An August 11, 1998, the Company granted options to purchase 15,690 Ordinary
Shares and 15,674,310 Redeemable Preference Shares under the terms of the
Management Share Option Scheme. The weighted average price for such options is
2.5 pence for both Ordinary Shares and Redeemable Preference Shares. The
weighted average vesting period for such options is 2.7 years.

On August 21, 1998, the Company issued 515,000 Ordinary Shares and
514,485,000 Redeemable Preference Shares to CCIC for cash at par under the
terms of the warrant. In addition, CCIC subscribed for 10,210 Ordinary Shares
and 10,199,790 Redeemable Preference Shares for cash at a premium of 1.5 pence
per share.

On August 21, 1998, the Company became an 80% owned subsidiary of CCIC. On
that same date, (i) all issued and unissued Redeemable Preference Shares were
redesignated as Ordinary Shares; and (ii) all existing options to purchase
shares in the Company were converted into options to purchase shares in CCIC at
the rate of 7 shares in CCIC for every 1000 shares in the Company.

27 Summary of differences between United Kingdom and United States generally
accepted accounting principles

These consolidated financial statements have been prepared in accordance
with UK GAAP, which differ in certain respects from US GAAP. The differences
that affect Home Service and Castle Transmission are set out below:

(a) Tangible fixed assets

During 1993 Home Service revalued upwards its investments in certain
identifiable tangible fixed assets. Such upward revaluation is not permissible
under US GAAP. Rather, depreciated historical cost must be used in financial
statements prepared in accordance with US GAAP.

In the period between April 1, 1996 and February 27, 1997 there were a
number of transfers of fixed assets to and from other parts of the BBC as
explained in note 10. For US GAAP purposes these transfers have been accounted
for under the as-if-pooling-of-interests method for transactions between
entities under common control.

F-60
<PAGE>

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(b) Deferred taxation

Under UK GAAP, deferred taxes are accounted for to the extent that it is
considered probable that a liability or asset will crystallise in the
foreseeable future. Under US GAAP, deferred taxes are accounted for on all
timing differences and a valuation allowance is established in respect of
those deferred tax assets where it is more likely than not that some portion
will remain unrealised. Deferred tax also arises in relation to the tax effect
of other US GAAP adjustments.

The Group accounts for costs of pensions under the rules set out in the UK
accounting standards. US GAAP is more prescriptive in respect of actuarial
assumptions and the allocation of costs to accounting periods.

(d) Capitalised interest

Under US GAAP, interest incurred during the construction periods of
tangible fixed assets is capitalised and depreciated over the life of the
assets.

(e) Redeemable preference shares

Under UK GAAP, preference shares with mandatory redemption features or
redeemable at the option of the security holder are classified as a component
of total shareholders' funds. US GAAP requires such redeemable preference
shares to be classified outside of shareholders' funds.

(f) Cash flow statement

Under US GAAP various items would be reclassified within the consolidated
cash flow statement. In particular, interest received, interest paid and
taxation would be part of net cash flows from operating activities, and
dividends paid would be included within net cash flow from financing. In
addition, under US GAAP, acquisitions and disposals would be included as
investing activities.

Movements in those current investments which are included under the heading
of cash under US GAAP form part of the movements entitled "Management of
liquid resources" in the consolidated cash flow statements.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and
Stockholders of Crown Castle
International Corp.:

We have audited the accompanying statement of net assets of Bell Atlantic
Mobile Tower Operations as of December 31, 1998, and the related statements of
revenues and direct expenses for each of the years in the two-year period ended
December 31, 1998. 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 audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the statement of net assets and the related
statements of revenues and direct expenses are free of material misstatement.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the statement of net assets and the related statements of
revenues and direct expenses. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall presentation of the statement of net assets and the
related statements of revenues and direct expenses. We believe that our audit
provides a reasonable basis for our opinion.

The statements of net assets and revenues and direct expenses were prepared
for the purpose of complying with the rules and regulations of the Securities
and Exchange Commission. As discussed in note 1, such statements do not reflect
certain corporate overhead expenses incurred by Bell Atlantic Mobile, the
contributor of the net assets, on behalf of the tower operations.

In our opinion, the statements referred to above present fairly, in all
material respects, the net assets of Bell Atlantic Mobile Tower Operations as
of December 31, 1998, and the related revenues and direct expenses for each of
the years in the two-year period ended December 31, 1998, in conformity with
generally accepted accounting principles.

1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

On December 8, 1998 Crown Castle International Corp. ("CCIC") and Bell
Atlantic Mobile and certain entities controlled by Bell Atlantic Mobile ("BAM")
entered into a formation agreement in order to create Crown Atlantic Company
LLC ("Crown Atlantic"). Under the terms of the agreement, BAM will contribute
tower structures and certain related assets while CCIC will contribute cash and
shares of its common stock to Crown Atlantic and its parent company,
respectively. The tower structures and related assets consist of the tower
facilities that were previously part of BAM's cellular operations. Their
locations span New York, New England, Philadelphia, Pittsburgh, Washington-
Baltimore and certain areas in the Southeast and Southwest.

Under the formation agreement, Crown Atlantic will assume all obligations
of BAM as landlord, licensor or tenant relating to the tower space leases with
respect to the period after the closing date. Crown Atlantic will also assume
all obligations of BAM subsequent to the closing date relating to the operation
of the towers and any contracts entered into by BAM during the ordinary course
of business of BAM relating to the towers but only to the extent that such
contracts were chosen to be included in the obligations assumed by Crown
Atlantic. Under the terms of the formation agreement, Crown Atlantic did not
assume certain liabilities as defined in the actual terms of the formation
agreement.

The accompanying statement of net assets reflects the assets to be
contributed by BAM to Crown Atlantic pursuant to the formation agreement. The
statement of net assets reflects BAM's historical carrying values of the
contributed assets, adjusted to exclude certain assets which will not be
contributed as part of the formation agreement.

The accompanying statements of revenue and direct expenses reflect
operations related to the tower assets to be contributed by BAM to Crown
Atlantic per the formation agreement. Certain direct and indirect operating
costs of BAM have been allocated and included in the costs of operations. The
allocated amounts totaled $3,501 and $3,694 for the years ended December 31,
1997 and 1998, respectively. Such allocations are based on determinations that
management believes are reasonable, but may not be necessarily indicative of
such costs incurred by Crown Atlantic in the future. The statements of revenues
and direct expenses do not include allocated costs related to general corporate
overhead, interest expense and income taxes and therefore may not be indicative
of future operations.

The accompanying statement of net assets and the related statements of
revenues and direct expenses were prepared for the purpose of complying with
the requirements of the Securities and Exchange Commission and are not intended
to be a complete presentation of Bell Atlantic Mobile's assets and liabilities
or revenues and expenses.

Summary of Significant Accounting Policies

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, the
disclosure of contingent assets and liabilities as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Basis of Presentation

On March 15, 1999, Crown Castle International Corp. ("CCIC") and Powertel,
Inc. ("Powertel") entered into an asset purchase agreement, whereby Powertel
will sell tower structures and certain related assets to CCIC. The tower
structures and related assets consist of the tower facilities that were
previously part of Powertel's PCS and cellular operations. Their locations span
Atlanta, Georgia; Jacksonville, Florida; Memphis, Tennessee; Jackson,
Mississippi; and Birmingham, Alabama and certain areas in Kentucky and
Tennessee.

The accompanying statement of net assets reflects the assets to be sold by
Powertel to CCIC pursuant to the asset purchase agreement. The statement of net
assets reflects Powertel's historical carrying values of the tower assets,
adjusted to exclude certain assets which will not be contributed as part of the
asset purchase agreement.

The accompanying statement of revenues and direct expenses reflects
operations related to the tower assets to be sold by Powertel to CCIC per the

not include allocated costs related to general corporate overhead, interest
expense and income taxes and therefore may not be indicative of future
operations.

Summary of Significant Accounting Policies

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, the
disclosure of contingent assets and liabilities as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Revenue Recognition

Site rental revenues are recognized on a monthly basis under lease
agreements. Site rental revenues represent charges for tower usage billed to
third party customers under lease arrangements. Revenue amounts received in
advance are deferred and recognized over the term of the lease agreement.

[D] UNDERWRITING

The Company and the underwriters for the offering named below have entered
into an underwriting agreement with respect to the notes. Subject to certain
conditions, each underwriter has severally agreed to purchase the number of
notes indicated in the following table.

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

Notes sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus.
Any notes sold by the underwriters to securities dealers may be sold at a
discount from the initial public offering price of up to % per note from the
initial public offering price. Any such securities dealers may resell any notes
purchased from the underwriters to certain other brokers or dealers at a
discount from the initial public offering price of up to % per note from the
initial public offering price. If all the notes are not sold at the initial
offering price, the underwriters may change the offering price and the other
selling terms.

The notes are a new issue of securities with no established trading market.
The Company has been advised by the underwriters that the underwriters intend
to make a market in the notes but are not obligated to do so and may
discontinue market making at any time without notice. No assurance can be given
as to the liquidity of the trading market for the notes.

In connection with the offerings, the underwriters may purchase and sell
notes in the open market. These transactions may include short sales,
stabilizing transactions and purchases to cover positions created by short
sales. Short sales involve the sale by the underwriters of a greater number of
notes than they are required to purchase in the offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the notes while the
offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased notes sold
by or for the account of such underwriter in stabilizing or short covering
transactions.

These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the notes. As a result, the price of the notes may
be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at
any time these transactions may be effected in the over-the-counter market or
otherwise.

The Company estimates that its share of the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately $ .

The Company has agreed to indemnify the several underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.

Shares sold by the U.S. Underwriters to the public will initially be
offered at the initial public offering price set forth on the cover of this
prospectus. Any shares sold by the U.S. Underwriters to securities dealers may
be sold at a discount of up to $ per share from the initial public offering
price. Any such securities dealers may resell any shares purchased from the
U.S. Underwriters to certain other brokers or dealers at a discount of up to
$ per share from the initial public offering price. If all the shares are not
sold at the initial offering price, the representatives may change the offering
price and the other selling terms.

The Company and the Selling Stockholders have entered into underwriting
agreements with the underwriters for the sale of shares outside the United

shares in both offerings are conditioned on each other. Goldman Sachs
International and Salomon Smith Barney are representatives of the underwriters

<PAGE>

The underwriters for each of the offerings have entered into an agreement
in which they agree to restrictions on where and to whom they and any dealer
purchasing from them may offer shares as a part of the distribution of the
shares. The underwriters also have agreed that they may sell shares among each
of the underwriting groups.

The Company and the Selling Stockholders have agreed with the underwriters
not to dispose of or hedge any of their common stock or securities convertible
into or exchangeable for shares of common stock during the period from the date
of this prospectus continuing through the date 90 days after the date of this

In connection with the offerings, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offerings.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while the offerings are in progress.

The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares
sold by or for the account of such underwriter in stabilizing or short covering
transactions.

These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the in the
over-the-counter market or otherwise.

The Company and the Selling Stockholders estimate that their shares of the
total expenses of the offerings, excluding underwriting discounts and
commissions, will be approximately $ and $ , respectively.

The Company and the Selling Stockholders have agreed to indemnify the
several underwriters against certain liabilities, including liabilities under
the Securities Act of 1933.

This prospectus may be used by the underwriters and other dealers in
connection with offers and sales of the shares, including sales of shares
initially sold by the underwriters in the offering being made outside of the
United States, to persons located in the United States.

Item 14. Indemnification of Directors and Officers

Section 145 of the General Corporation Law of the State of Delaware
("DGCL") provides that a corporation has the power to indemnify any director or
officer, or former director or officer, who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation) against the expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement
actually and reasonably incurred by them in connection with the defense of any
action by reason of being or having been directors or officers, if such person
shall have acted in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, provided that such person had no reasonable
cause to believe his conduct was unlawful, except that, if such action shall be
in the right of the corporation, no such indemnification shall be provided as
to any claim, issue or matter as to which such person shall have been judged to
have been liable to the corporation unless and to the extent that the Court of
Chancery of the State of Delaware (the "Court of Chancery"), or any court in
which such suit or action was brought, shall determine upon application that,
in view of all of the circumstances of the case, such person is fairly and
reasonably entitled to indemnify for such expenses as such court shall deem
proper.

Accordingly, the Restated Certificate of Incorporation of the Company
(Exhibit 3.1) provides that the Company shall, to the maximum extent permitted
under the DGCL, indemnify each person who is or was a director or officer of
the Company. The Company may, by action of the Board of Directors, indemnify
other employees and agents of the Corporation, directors, officers, employees
or agents of a subsidiary, and each person serving as a director, officer,
partner, member, employee or agent of another corporation, partnership, limited
liability company, joint venture, trust or other enterprise, at the request of
the Company, with the same scope and effect as the indemnification of directors
and officers of the Company. Notwithstanding the foregoing, the Company shall
be required to indemnify any person seeking indemnification in connection with
a proceeding (or part thereof) initiated by such person only if such proceeding
(or part thereof) was authorized by the Board of Directors or is a proceeding
to enforce such person's claim to indemnification pursuant to the rights
granted by the

II-1
<PAGE>

Restated Certificate of Incorporation or otherwise by the Company. The Company
may also enter into one or more agreements with any person which provide for
indemnification greater or different than that provided in the Restated
Certificate of Incorporation.

Furthermore, a director of the Company shall not be liable to the Company
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability (1) for any breach of the director's duty of
loyalty to the Company or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (3) under Section 174 of the DGCL, or (4) for any transaction from which
the director derived an improper personal benefit.

The Company's By-laws provide that each person who was or is made a party
or is threatened to be made a party to or is involved in any manner in any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative ("Proceeding"), by reason of the fact
that he or she or a person of whom he or she is the legal representative is or
was a director or officer of the Company or, while a director or officer of the
Company, a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall be indemnified and
held harmless by the Company to the fullest extent permitted by the DGCL. Such
indemnification shall continue as to a person who has ceased to be a director
or officer and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that the Company shall indemnify any such
person seeking indemnification in connection with a Proceeding (or part
thereof) initiated by such person only if such Proceeding (or part thereof) was
authorized by the Board of Directors or is a Proceeding to enforce such
person's claim to indemnification pursuant to the rights granted by the
Company's By-laws. The Company shall pay the expenses incurred by any person
described in the first two sentences of this paragraph in defending any such
Proceeding in advance of its final disposition upon, to the extent such an
undertaking is required by applicable law, receipt of an undertaking by or on
behalf of such person to repay such amount if it shall ultimately be determined
that such person is not entitled to be indemnified by the Company as authorized
in the Company's By-laws or otherwise.

The Company's By-laws further provide that the indemnification and the
advancement of expenses incurred in defending a Proceeding prior to its final
disposition provided by, or granted pursuant to, the Company's By-laws shall
not be exclusive of any other right which any person may have or hereafter
acquire under any statute, provision of the Restated Certificate of
Incorporation, other provision of the Company's By-laws or otherwise. The
Company may also maintain insurance, at its expense, to protect itself and any
person who is or was a director, officer, partner, member, employee or agent of
the Company or a subsidiary or of another corporation, partnership, limited
liability company, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Company would have the power to
indemnify such person against such expense, liability or loss under the DGCL.

The Company's By-laws further provide that the Company may, to the extent
authorized from time to time by the Board of Directors, grant rights to
indemnification, and rights to be paid by the Company the expenses incurred in
defending any Proceeding in advance of its final disposition, to any person who
is or was an employee or agent (other than a director or officer) of the
Company or a subsidiary thereof and to any person who is or was serving at the
request of the Company or a subsidiary thereof as a director, officer, partner,
member, employee or agent of another corporation, partnership, limited
liability company, joint venture, trust or other enterprise, including service
with respect to employee benefit plans maintained or sponsored by the Company
or a subsidiary thereof, to the fullest extent of the provisions of the
Company's By-laws with respect to the indemnification and advancement of
expenses of directors and officers of the Company.

Item 15. Recent Sales of Unregistered Securities

In each of the sales described below, unless otherwise indicated, the
Company (or the relevant predecessor) relied on Section 4(2) of the Securities
Act of 1933 for exemption from registration. No brokers or underwriters were
used in connection with any of such sales. The recipients of securities in each
such transaction represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the share
certificates, warrants and notes issued in such transactions. All recipients
had adequate access, through their relationship with the Company, to
information about the Company.

Through May 31, 1998, the Company had raised approximately $367.0 million
through private sales of debt and equity securities in a series of private
placements with various institutional and other accredited investors and
certain employees of the Company as described below.

CTC Investment. On January 11, 1995, CTC, a predecessor to CCIC, sold (i)

exchanged for five shares of similar stock of CCIC and (iv) the remaining CTC
Notes ($3,125,268 principal amount) becoming convertible into shares of Series

Schedule I--Condensed Financial Information of Registrant

All other schedules are omitted because they are not applicable or because
the required information is contained in the financial statements or notes
thereto included in this Registration Statement.

Item 17. Undertakings

Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to 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 person 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 such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act,
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, 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.

NOTES TO FINANCIAL STATEMENTS (Unconsolidated)

1.Investment in Subsidiaries

The Company's investment in subsidiaries is presented in the accompanying
unconsolidated financial statements using the equity method of accounting.
Under the terms of the Senior Credit Facility, the CTI Credit Facility and the
CTI Bonds, the Company's subsidiaries are limited in the amount of dividends
which can be paid to the Company. For CCI, the amount of such dividends is
limited to (i) $6,000,000 per year until October 31, 2002, and $33,000,000 per
year thereafter, and (ii) an amount to pay income taxes attributable to the
Company's Restricted Subsidiaries. CTI is effectively precluded from paying
dividends. The restricted net assets of the Company's subsidiaries totaled
approximately $826,321,000 at December 31, 1998.

2.Long-term Debt

Long-term debt consists of the Company's 10 5/8% Senior Discount Notes due
2007.

3.Income Taxes

Income taxes reported in the accompanying unconsolidated financial
statements are determined by computing income tax assets and liabilities on a
consolidated basis, for the Company and members of its consolidated federal
income tax return group, and then reducing such consolidated amounts for the
amounts recorded by the Company's subsidiaries on a separate tax return basis.
