THE COMPANY

The Company is a leading U.S. and international provider of wireless
communications and broadcast transmission infrastructure and related services.
The Company owns, operates and manages towers, rooftop sites and broadcast
transmission networks, and provides a full range of complementary services
including network design and site selection, site acquisition, site development
and construction, antenna installation and network management and maintenance.
The Company has 19 years of experience in the ownership, leasing and management
of wireless communications sites and a 75-year history of broadcast
transmission and network management. Based on its industry position and
experience, the Company believes it is positioned to capitalize on global
growth opportunities arising from (i) the expansion of existing networks and
the introduction of new networks in the wireless communications industry, (ii)
the consolidation of tower ownership generally, including the transfer of
infrastructure ownership from major wireless communications carriers to
independent infrastructure providers, (iii) the ongoing privatization of state-
run broadcast transmission networks around the world and (iv) the widespread
introduction of digital transmission technology in the broadcasting industry.
For the year ended December 31, 1997 and the six months ended June 30, 1998,
the Company had pro forma revenues of $180.9 million and $95.0 million,
respectively.

The Company's site rental business involves leasing antenna space to
customers on its owned and managed towers and rooftop sites. The Company
generally receives fees for installing a customer's equipment and antennas on a
tower and also receives monthly rental payments from customers under site
leases that typically range in term from three to five years. The Company's
major site rental customers include Aerial Communications, AT&T Wireless, Bell
Atlantic Mobile, BellSouth Mobility, Motorola, Nextel, PageNet, Sprint PCS and
TSR Wireless in the United States and Cellnet, National Transcommunications
Limited, One2One, Orange Personal Communications and Vodafone in the United
Kingdom.

The Company's broadcast transmission business includes both the transmission
of analog and digital television and radio broadcasts and the construction of
new multiple tenant broadcast towers. In the United Kingdom, the Company
provides analog transmission services for two national television services,
seven national radio services and 37 local radio stations through its network
of 3,465 transmitters. These services are provided under long-term contracts
with the British Broadcasting Corporation (the "BBC") and two national
commercial radio companies. In addition, the Company has long-term contracts to
provide digital transmission services to the BBC and British Digital
Broadcasting Limited ("BDB"), which together are the holders of four of the six
multiplexes for digital

1
<PAGE>

terrestrial television broadcasting throughout the United Kingdom. In the
United States, the Company plans to build new multiple tenant broadcast towers
in locations where additional tower capacity is required to accommodate digital
transmission equipment and analog transmission equipment displaced from
existing towers.

The Company has developed, maintains and deploys primarily for its own use
extensive wireless communications and broadcast transmission network design and
radio frequency engineering expertise, as well as site acquisition, site
development and construction and antenna installation capabilities. The Company
has a team of over 300 engineers with state-of-the-art wireless communications
and broadcast transmission network design and radio frequency engineering
expertise. The Company plans to leverage its technical expertise and
operational experience to enter into build-to-suit and purchase contracts with,
and to enter into joint ventures to own and operate the wireless communications
infrastructure of, various wireless communications carriers around the world.
The Company believes the primary criteria of such carriers in selecting a
company to construct, own or operate their wireless communications
infrastructure will be the company's capability to maintain the integrity of
their networks, including their transmission signals. Therefore, the Company
believes that those companies with a proven track record of providing network
design and site selection, site acquisition, site development and construction
and antenna installation ("end-to-end services") will be best positioned to
successfully acquire access to such wireless communications infrastructure.

As of June 30, 1998, the Company owned or managed 1,244 towers and 66 revenue
producing rooftop sites. In addition, the Company had 1,217 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. The Company's
major tower footprints consist of 754 owned and managed towers located across
the United Kingdom, 207 owned and managed towers located in western
Pennsylvania (primarily in and around the greater Pittsburgh area), 185 owned
and managed towers located in the southwestern United States (primarily in
Texas), 14 owned towers located on mountaintops across Puerto Rico and 22 owned
towers along I-95 in North Carolina and South Carolina. In addition, the
Company is currently constructing 55 new towers on existing sites and has 38
site acquisition projects in process for sites for its own use.

The Company is actively seeking opportunities for strategic acquisitions of
communications sites and transmission networks and is currently pursuing a
number of potential significant acquisitions, investments and joint venture
opportunities. In connection with a site marketing agreement recently entered
into between the Company and BellSouth Mobility, the Company and BellSouth have
agreed to explore future arrangements relating to the ownership, utilization
and management of BellSouth's tower sites throughout the United States. The
Company is also intending to submit a bid in connection with an auction by a
major Regional Bell Operating Company of its U.S. wireless communications
infrastructure. Similarly, the Company has bid on the tower assets, which
encompass more than 250 U.S. tower sites, currently being auctioned by Vanguard
Cellular. In addition to those U.S. opportunities, the Company is pursuing
acquisition opportunities in Australia and New Zealand, including in certain
instances together with other partners. For example, the Company, together with
Fay Richwhite & Company Limited and Berkshire Partners LLC, has submitted a bid
in respect of a wireless communications network, including its tower
infrastructure and radio frequency spectrum. If the bid is successful and the
transaction is consummated, the Company anticipates that it would invest up to
approximately $50.0 million for a substantial minority interest in the acquired
business. The Company is also pursuing acquisition opportunities in connection
with privatizations of state-owned networks. Any of the foregoing could result
in an agreement with respect to a significant acquisition, investment or joint
venture in the near term. However, the Company has not entered into any
agreements in respect of, and believes that there are a number of competing
bidders for, these opportunities. As a result, the Company does not believe
that any of these acquisition opportunities have become probable. Therefore,
there can be no assurance that the Company will consummate any of the foregoing
transactions in the near term or at all. See "Risk Factors--Broad Discretion in
Application of Proceeds" and "Risk Factors--Managing Integration and Growth".

INDUSTRY BACKGROUND

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
communications 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 communications 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 (known as "DTV" in the United States and "DTT" in the United
Kingdom). In the United States, the Federal Communications Commission (the
"FCC") has required affiliates of 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 with digital transmission expected to commence on a commercial
basis in late 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.

3
<PAGE>

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.

BUSINESS STRATEGY

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

. MAXIMIZE UTILIZATION OF TOWER CAPACITY. The Company is seeking to take
advantage of the substantial operating leverage of its site rental
business by increasing the number of antenna leases on its owned and
managed communications sites. The Company believes that many of its
towers have significant capacity available for additional antenna space
rental and that increased utilization of its tower capacity can be
achieved at low incremental cost. For example, prior to the Company's
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. The Company believes there is
substantial demand for such capacity. In addition, the Company believes
that the extra capacity on its 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 the Company's attractive existing tower
footprints. Further, the Company intends to selectively build and
acquire additional towers to improve the coverage of its existing tower
footprints to further increase their attractiveness. The Company intends
to use targeted sales and marketing techniques to increase utilization
of and investment return on its existing, newly constructed and acquired
towers.

. LEVERAGE EXPERTISE OF CCI AND CTI PERSONNEL TO IMPLEMENT GLOBAL GROWTH
STRATEGY. The Company is seeking to leverage the skills of its personnel
in the United States and the United Kingdom. The Company believes that
its ability to manage wireless communications and broadcast transmission
networks, including the transmission of signals, will be an important
competitive advantage in its pursuit of global growth opportunities.
With its wireless communications and broadcast transmission network
design and radio frequency engineering expertise, the Company is well
positioned (i) to partner with major wireless communications carriers to
assume ownership of their existing towers, (ii) to provide build-to-suit
towers for wireless communications carriers and broadcasters and (iii)
to acquire existing broadcast transmission networks that are being
privatized around the world.

. PARTNER WITH WIRELESS COMMUNICATIONS CARRIERS TO ASSUME OWNERSHIP OF
THEIR EXISTING TOWERS. The Company is seeking to partner with major
wireless communications carriers in order to assume ownership of their
existing towers directly or through joint ventures. The Company believes
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 signals. Therefore, the Company
believes 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. The Company is
currently in discussions with major wireless communications carriers in
the United States to form joint ventures that would own and operate
their towers and believes that similar opportunities will arise globally
as the wireless communications industry further expands.

4
<PAGE>

. PROVIDE BUILD-TO-SUIT TOWERS FOR WIRELESS COMMUNICATIONS CARRIERS AND
BROADCASTERS. As wireless communications 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 DTV 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. The Company is aggressively pursuing
these build-to-suit opportunities, leveraging on its ability to offer
end-to-end services. In addition, the Company intends to pursue build-
to-suit opportunities through any joint venture or similar arrangement
it establishes in connection with the acquisition of existing towers
from wireless communications carriers.

. ACQUIRE EXISTING TRANSMISSION NETWORKS. In 1997, CTI successfully
acquired the privatized domestic broadcast transmission network of the
BBC. In addition, the Company is implementing the roll-out of digital
television transmission services throughout the United Kingdom. As a
result of this experience, the Company is 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 acquiror
the ability to offer unused antenna capacity to new and existing radio
and television broadcasters and wireless communications carriers, as
well as to install new technologies such as digital terrestrial
transmission services. In addition, the Company's experience in
broadcast transmission services allows the Company to consider, when
attractive opportunities arise, acquiring wireless transmission networks
as well as the acquisition of associated wireless communications
infrastructure. The Company is currently pursuing a number of
international acquisition and privatization opportunities.

. CAPITALIZE ON MANAGEMENT EXPERIENCE. The Company's management team has
extensive experience in the tower industry and in the management of
broadcast transmission networks. Many of the senior executives have
worked together for an extended period, which enables them to leverage
their collective strengths in a rapidly changing industry environment.
In addition, management is highly motivated to produce strong operating
results based on their stock ownership in the Company.

BACKGROUND

Founded in 1994, the Company acquired 127 towers located in Texas, Colorado,
New Mexico, Arizona, Oklahoma and Nevada from Pittencrieff Communications, Inc.
("PCI") in 1995. The Company subsequently continued to build its business
through a variety of transactions, including (i) the acquisition in 1996 of
Motorola's SMR and microwave system in Puerto Rico (the "Puerto Rico System"),
which included 15 communication sites (the "Puerto Rico Acquisition"), (ii) the
purchase through a series of transactions in 1996 and 1997 of TEA Group
Incorporated ("TEA"), a leading domestic and international site acquisition
firm (the "TEA Acquisition"), and (iii) the purchase in February 1997 of a
34.3% ownership interest in CTI (the "CTI Investment").

In August 1997, the Company enhanced its tower footprints and domestic
network services offering by consummating the acquisition of the assets of
Crown Communications (a proprietorship owned by Robert A. and Barbara Crown),
and a merger of subsidiaries of the Company with and into Crown Network
Systems, Inc. ("CNSI") and Crown Mobile Systems, Inc. ("CMSI"). The acquisition
of the assets of Crown Communications and the merger of subsidiaries of the
Company with and into CNSI and CMSI are collectively referred to herein as the
"Crown Merger". The assets acquired through the Crown Merger included 61 owned
towers and exclusive rights to lease antenna space on 147 other towers and
rooftop sites, most of which are located in and around the greater Pittsburgh
area, giving the Company a significant presence in that market. The remaining
acquired sites are located in other areas of Pennsylvania, West Virginia,
Kentucky, Ohio and Delaware.

THE ROLL-UP

On April 24, 1998, the Company entered into a Share Exchange Agreement
pursuant to which, concurrently with the consummation of the Offering, (i) the
shareholders of CTSH (other than the Company, TdF and DFI) will exchange their
shares of capital stock of CTSH for shares of Common Stock of the Company and
(ii) DFI will exchange its shares of capital stock of CTSH for shares of Class
A Common Stock of the Company. In connection with such exchanges, the Company
will exercise warrants to acquire additional shares of capital stock of CTSH
and subscribe for additional shares of capital stock of CTSH. Such transactions
are collectively referred to herein as the "Exchange". Upon consummation of the
Exchange, the Company will own 80.0% of CTSH and TdF will own the remaining
20.0%. Immediately prior to the Exchange, (i) each share of the Company's
currently outstanding Class A Common Stock, par value $.01 per share (the
"Existing Class A Common Stock"), will be converted into 1.523148 shares of
Common Stock, (ii) each share of the Company's currently outstanding Class B

RECENT FINANCINGS

On October 31, 1997, Castle Tower Corporation ("CTC"), then a wholly owned
subsidiary of CCIC, borrowed approximately $94.7 million (the "October Bank
Financing") under a Loan Agreement dated April 26, 1995, as amended on June 26,
1996, January 17, 1997, April 3, 1997 and October 31, 1997 (the "Senior Credit
Facility"). In addition, concurrently with the October Bank Financing, CCIC
privately placed $36.5 million of senior convertible preferred stock (the
"Senior Convertible Preferred Stock") and warrants to purchase shares of Common
Stock of CCIC. The proceeds of the October Bank Financing and the private
placement of Senior Convertible Preferred Stock were used to repay a seller
note issued in connection with the Crown Merger, to repay loans outstanding
under a credit agreement at Crown Communications and to pay related fees and
expenses. The October Bank Financing, the private placement of the Senior
Convertible Preferred Stock and the application of the proceeds therefrom are
collectively referred to herein as the "October Refinancing".

On November 20, 1997, the Company privately placed (the "1997 Notes
Offering") $251.0 million principal amount at maturity ($150,010,150 initial
accreted value) of its 10 5/8% Senior Discount Notes due 2007 (the "Notes").
The net proceeds to the Company from the 1997 Notes Offering were used to repay
substantially all outstanding indebtedness of the Company, including the
approximately $94.7 million of indebtedness incurred under the Senior Credit
Facility in connection with the October Refinancing, and to pay related fees
and expenses with the balance being used for general corporate purposes. The
October Refinancing, the 1997 Notes Offering and the application of the net
proceeds from the 1997 Notes Offering, are collectively referred to herein as
the "1997 Refinancing".

- --------
(a) Included in costs of operations for site rental and broadcast transmission
for the six months ended June 30, 1998 are non-cash compensation charges
for $1.4 million related to the issuance of stock options for 170,000
ordinary shares and 169,830,000 preference shares of CTSH to certain
employees of CTI. In connection with the Roll-Up, such stock options will
be converted into options for Common Stock of the Company. See
"Management--Stock Option Plans--CTI Stock Option Plans".

(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. Included in corporate development expenses for the six
months ended June 30, 1998 are non-cash compensation charges for $1.8
million related to the issuance of stock options for approximately 168,000
ordinary shares and 167,832,000 preference shares of CTSH to certain
executives at CTI. In connection with the Roll-Up, such stock options will
be converted into options for Common Stock of the Company. See
"Management--Stock Option Plans--CTI Stock Option Plans". CCIC expects to
record non-cash compensation charges related to the issuance of stock
options to certain employees and executives. Such charges are expected to
amount to $10.6 million in 1998, recognized upon completion of the
Offering, and approximately $1.6 million per year thereafter through 2003.

(c) Represents the aggregate number of sites of CCIC and its acquired
businesses (including Crown) and CTI for each period.
(d) As of June 30, 1998, the Company had contracts with 1,283 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 the Company has arranged a lease of space on
such rooftop and, as such, is receiving payments in respect of its
management contract. The Company generally does not receive any payment for
rooftops under management unless the Company actually leases space on such
rooftops to third parties. As of June 30, 1998, the Company had 1,217
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, the Company had 54 revenue producing rooftop sites
that were occupied by the Company's transmitters but were not available for
leasing to customers.
(e) EBITDA is defined as operating income (loss) plus depreciation and
amortization. EBITDA is presented as additional information because
management believes it to be a useful indicator of the Company'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, the Company's 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, 1997 and the six months ended June 30, 1998,
earnings were insufficient to cover fixed charges by $33.2 million and
$20.4 million, respectively.
(g) Reflects the conversion of the outstanding shares of Senior Convertible
Preferred Stock into shares of Common Stock in the Senior Preferred
Conversion.
(h) Total interest expense for the six months ended June 30, 1998 includes
amortization of deferred financing costs and discount of $8.5 million for
CCIC and $0.4 million for CTI.

(i) Net debt represents total debt less cash and cash equivalents.

"Predecessor") for the year ended March 31, 1996 and the eleven and two months
ended February 27, 1997, (ii) summary historical consolidated financial data of
CTI after such acquisition for the one month ended March 31, 1997, for the
three months ended June 30, 1997 and for the nine months ended December 31,
1997, and (iii) summary historical consolidated financial data of CTI as of and
for the six months ended June 30, 1998. The summary 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 summary 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 summary historical financial data
for the two months ended February 27, 1997 have been derived from the unaudited
financial statements of the Predecessor, and the summary historical financial
data for the three months ended June 30, 1997 and as of and for the six months
ended June 30, 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 three months ended June 30, 1997, the nine months ended December 31, 1997
and the six months ended June 30, 1998 are not necessarily indicative of the
results of operations of CTI that may be expected for the entire year. 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--Holding Company Structure; Dependence on Dividends to Meet Cash
Requirements or Pay Dividends". The information set forth below should be read
in conjunction with "Selected Financial and Other Data of CTI", "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 Prospectus.

(a) CTI publishes its consolidated financial statements in pounds sterling. For
the convenience of the reader, the information set forth above contains
translations of pound sterling amounts into U.S. dollars at the Noon Buying
Rate on June 30, 1998, of (Pounds)1.00 = $1.6695. No representation is made
that the pound sterling amounts have been, could have been or could be
converted into U.S. dollars at the rate indicated or any other rates. On
July 31, 1998, the Noon Buying Rate was (Pounds)1.00 = $1.6388.

(b) Included in costs of operations for site rental and broadcast transmission

(c) 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. Included in corporate development expenses for the six
months ended June 30, 1998 are non-cash compensation charges for
(Pounds)1.1 million ($1.8 million) related to the issuance of stock options
to certain executives at CTI.

(d) As of June 30, 1998, CTI's 54 revenue producing rooftop sites were occupied
by its transmitters but were not available for leasing to customers.

(e) EBITDA is defined as operating income (loss) plus depreciation and
amortization. EBITDA is presented as additional information because
management believes it to be a useful indicator of CTI'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, CTI's measure of EBITDA may not be comparable to
similarly titled measures of other companies.

RISK FACTORS

Prospective investors should consider carefully the risk factors set forth
below, as well as the other information appearing in this Prospectus, before
making any investment in the Common Stock.

MANAGING INTEGRATION AND GROWTH

The Company's ability to implement its growth strategy depends, in part, on
its successes in integrating its acquisitions, investments, joint ventures and
strategic alliances into the Company's operations. The Company has grown
significantly over the past 18 months through acquisitions. The Crown Merger
in August 1997 was significantly larger than the Company's previous
acquisitions and represented a substantial increase in the scope of the
Company's business. Crown's revenues for fiscal 1996 were $19.4 million. In
contrast, CCIC's revenues for fiscal 1996 were $6.2 million. Similarly, the
Roll-Up will result in the Company having majority ownership of CTI, which had
consolidated revenues in the twelve months ended December 31, 1997 of
(Pounds)76.0 million ($124.5 million). Successful integration of these
transactions will depend primarily on the Company's ability to manage their
combined operations and to integrate their existing management with and into
CCIC's management. There can be no assurance that the Company can successfully
integrate these acquired businesses or any future acquisitions into its
business or implement its plans without delay and any failure or any inability
to do so may have a material adverse effect on the Company's financial
condition and results of operations.

Implementation of the Company's acquisition strategy may impose significant
strains on the Company's management, operating systems and financial
resources. Failure by the Company to manage its growth or unexpected
difficulties encountered during expansion could have a material adverse effect
on the Company's financial condition and results of operations. The pursuit
and integration of acquisitions, investments, joint ventures and strategic
alliances will require substantial attention from the Company's senior
management, which will limit the amount of time available to devote to the
Company's existing operations. Future acquisitions by the Company could result
in the incurrence of substantial amounts of debt and contingent liabilities
and an increase in amortization expenses related to goodwill and other
intangible assets, which could have a material adverse effect upon the
Company's financial condition and results of operations.

SUBSTANTIAL LEVERAGE; RESTRICTIONS IMPOSED BY THE TERMS OF THE COMPANY'S
INDEBTEDNESS

The Company is highly leveraged. As of June 30, 1998, after giving pro forma
effect to the Roll-Up, the Offering and the Senior Preferred Conversion, the
Company had total consolidated indebtedness of approximately $465.3 million
and total consolidated stockholders' equity of approximately $758.3 million.
Also, after giving pro forma effect to the Roll-Up, the Company's earnings
would have been insufficient to cover fixed charges by $33.2 million for
fiscal 1997. CCIC and its subsidiaries will be permitted to incur additional
indebtedness in the future. See "Capitalization", "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "Description of Certain Indebtedness".

The degree to which the Company is leveraged could have significant adverse
consequences to the Company, including, but not limited to: (i) increasing the
Company's vulnerability to general adverse economic and industry conditions,
(ii) limiting the Company's ability to obtain additional financing to fund
future working capital, capital expenditures and other general corporate
requirements, (iii) requiring the dedication of a substantial portion of the
Company's cash flow from operations to the payment of principal of, and
interest on, its indebtedness, thereby reducing the availability of such cash
flow to fund working capital, capital expenditures or other general corporate
purposes, (iv) limiting the Company's flexibility in planning for, or reacting
to, changes in its business and the industry and (v) placing the Company at a
competitive disadvantage vis-a-vis less leveraged competitors. See
"Capitalization", "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources" and "Description
of Certain Indebtedness".

The Company's ability to meet its debt service or to fund planned capital
expenditures, will depend on its future performance, which, to a certain
extent, is subject to general economic, financial, competitive, legislative,

17
<PAGE>

regulatory and other factors that are beyond its control. The Company's
business strategy contemplates substantial capital expenditures in connection
with the expansion of its tower footprints. Based on the Company's current
operations and anticipated revenue growth, management believes that cash flow
from operations and available cash, together with the net proceeds of the
Offering and available borrowings under the Senior Credit Facility and CTI
Credit Facility (as defined), will be sufficient to fund the Company's
anticipated capital expenditures for the foreseeable future. However, in the
event the Company consummates any significant acquisitions, including any of
the significant acquisitions that the Company is currently pursuing, or
exceeds its currently anticipated capital expenditures, the Company
anticipates that it will need to seek additional equity or debt financing to
fund its business plan. Failure to obtain any such financing could require the
Company to significantly reduce its planned capital expenditures and forego
these acquisition opportunities and could have a material adverse effect on
the Company's ability to achieve its business strategy. In addition, the
Company may need to refinance all or a portion of its indebtedness on or prior
to its scheduled maturity. There can be no assurance that the Company will
generate sufficient cash flow from operations in the future, that anticipated
revenue growth will be realized or that future borrowings, equity
contributions or loans from affiliates will be available in an amount
sufficient to service its indebtedness and make anticipated capital
expenditures. In addition, there can be no assurance that the Company will be
able to effect any required refinancings of its indebtedness on commercially
reasonable terms or at all. See "--Holding Company Structure; Dependence on
Dividends to Meet Cash Requirements or Pay Dividends" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations".

The terms of the Company's debt instruments contain numerous restrictive
covenants, including but not limited to covenants that restrict the ability of
the Company and its subsidiaries to incur indebtedness, pay dividends, create
liens, sell assets and engage in certain mergers and acquisitions. In
addition, some of such indebtedness requires certain of the Company's
subsidiaries to maintain certain financial ratios. The ability of the Company
to comply with the covenants and other terms of its indebtedness and to
satisfy its respective debt obligations will depend on the future operating
performance of the Company. In the event the Company fails to comply with the
various covenants contained in its debt instruments, it would be in default
thereunder, and in certain of such cases, the maturity of substantially all of
its long-term indebtedness could be accelerated. See "Description of Certain
Indebtedness".

RISKS RELATED TO AGREEMENTS WITH TDF

In connection with the Roll-Up, the Company has entered into certain
agreements with TdF that grant TdF certain significant protective rights with
respect to the governance of the Company and CTI, the ownership of CTI and the
disposition of its shares in the Company and CTI. See "The Roll-Up".

Governance Rights. The Company has granted to TdF certain rights with
respect to the governance of the Company, including (i) the ability to
prohibit the Company from entering into certain material transactions,
(ii) the issuance to TdF of shares of Class A Common Stock, which gives TdF
the right to elect up to two of the twelve members of the Company's Board of
Directors, and (iii) subject to certain conditions, the inclusion on each of
the executive committee, the nominating and corporate governance committee of
the Company's Board of Directors of at least one director elected by TdF. In
addition to its governance rights with respect to the Company, TdF has
significant governance rights with respect to CTI which, after giving pro
forma effect to the Roll-Up, would have accounted for approximately 68.8% of
the Company's revenues in 1997. Following consummation of the Roll-Up,
although TdF will hold only a 20% equity interest in CTI, TdF's rights with
respect to CTI will be generally characteristic of the rights of a 50% partner
to a joint venture.

While TdF's rights with respect to the governance of the Company and CTI are
subject to certain limitations and forfeiture by TdF in certain circumstances,
during the period in which such rights are exercisable by TdF, such rights
will give TdF (whose ultimate parent is France Telecom) and its affiliates the
ability to exert significant control over the governance of the Company and
CTI. The exercise of such rights by TdF may be contrary to the interests of
the Company's other stockholders generally, and may prevent the Company and/or
CTI from entering into transactions that the Company's Board of Directors
deems to be in the best interests of the Company and its stockholders. See "--
Anti-Takeover Provisions".

18
<PAGE>

CTSH Option. In addition to TdF's governance rights with respect to the
Company and CTI described above, in the event of (i) the sale of all or
substantially all of the Company's assets, (ii) a merger, consolidation or
similar transaction that would result in any person owning more than 50% of
the Company's voting power or equity securities, (iii) an unsolicited
acquisition by any person of more than 25% (or 30% if the Company elects by
notice in writing to TdF) of such securities or (iv) certain other
circumstances relating to an acquisition by any person that would give rise to
a right of the BBC to terminate the BBC Analog Transmission Contract (as
defined) or the BBC Digital Transmission Contract (as defined) (each, a
"Triggering Event"), which Triggering Event is not approved by TdF, TdF will
have the right, subject to certain conditions, to acquire all of the Company's
shares of capital stock of CTSH or to require the Company to purchase all of
TdF's shares of capital stock of CTSH, in each case at fair market value.
Further, immediately prior to the occurrence of a Triggering Event, TdF will
have the right to require the Company to purchase 50% of the Class A Common
Stock held by TdF and its affiliates in cash at a price per share equal to the
price to be paid upon consummation of the Triggering Event. See "The Roll-Up".

TdF's right to purchase the Company's shares of CTSH upon a Triggering Event
may have the effect of preventing a change of control of the Company. If the
Company were required to sell its shares in CTSH to TdF, it would no longer
own or conduct the CTI business. Alternatively, if the Company were required
to purchase all of TdF's shares of CTSH and/or purchase 50% of the Class A
Common Stock held by TdF and its affiliates, there can be no assurance that
the Company would have the necessary funds to do so or that such purchase
would be permitted under the terms of the Company's debt instruments. If the
Company did not have sufficient funds to purchase TdF's shares of capital
stock of CTSH or TdF's and TdF's affiliates' shares of Class A Common Stock,
the Company would need to seek additional financing. There can be no assurance
that any such financing could be obtained on terms acceptable to the Company,
or at all. In the absence of such financing, the Company could be forced to
dispose of other assets under circumstances that might not be favorable to
realizing the highest price for such assets in order to obtain the funds to
purchase the TdF shares. In addition, the obligation to purchase the TdF
shares could result in an event of default under the terms of the Company's
outstanding indebtedness.

Liquidity Rights. If on or before the second anniversary of the consummation
of the Roll-Up (i) TdF has not exchanged its shares of capital stock of CTSH
in accordance with the Governance Agreement (as defined) or (ii) TdF has
ceased to be Qualified (as defined) for purposes of the Governance Agreement,
TdF will thereafter have the right to require the Company to purchase all of
TdF's shares of capital stock of CTSH at their fair market value. The Company
may elect to pay for such shares either (i) in cash or (ii) in shares of its
Common Stock at a discount of 15% to the market value of such Common Stock.
See "The Roll-Up". There can be no assurance that the Company will have
sufficient funds to purchase such shares for cash in connection with any put
of TdF's shares of capital stock of CTSH. If the Company does not have
sufficient funds for such purchase, it would either have to seek additional
financing or purchase such shares with its Common Stock. There can be no
assurance that any such financing could be obtained on terms acceptable to the
Company, if at all. If the Company were to issue shares of its Common Stock to
effect the purchase, such issuance would result in substantial dilution of the
Company's other stockholders, could adversely affect the market price of the
Common Stock and could impair the Company's ability to raise additional
capital through the sale of its equity securities. See "--Dilution".

BROAD DISCRETION IN APPLICATION OF PROCEEDS

A substantial portion of the estimated net proceeds from the Offering will
be allocated to the Company's working capital and general corporate purposes
and may be applied to as yet unidentified acquisitions, investments or joint
ventures in the United States or abroad. Due to the number and variability of
factors that will be analyzed before the Company determines how to use such
net proceeds, the Company will have broad discretion in allocating a
significant portion of the net proceeds from the Offering without any action
or approval of the Company's stockholders. Accordingly, investors will not
have the opportunity to evaluate the economic, financial and other relevant
information that will be considered by the Company in determining the
application of such net proceeds. See "Use of Proceeds".

19
<PAGE>

HOLDING COMPANY STRUCTURE; DEPENDENCE ON DIVIDENDS TO MEET CASH REQUIREMENTS
OR PAY DIVIDENDS

CCIC 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 is distributions with respect to its
ownership interest in its subsidiaries from the net earnings and cash flow
generated by such subsidiaries. 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, will permit such dividends or distributions.
Furthermore, the terms of the Senior Credit Facility and the Notes place
restrictions on CCI's ability, and the terms of the CTI Credit Facility and
the CTI Bonds (as defined) 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 certain 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 "--
Substantial Leverage; Restrictions Imposed by the Terms of the Company's
Indebtedness" and "Description of Certain Indebtedness".

RISKS ASSOCIATED WITH CONSTRUCTION AND ACQUISITIONS OF TOWERS

The Company's growth strategy depends on its ability to construct, acquire
and operate towers in conjunction with the expansion of wireless
communications carriers. As of June 30, 1998, the Company had 55 towers under
construction and had plans to commence construction on an additional 117
towers by the end of 1998. The Company's ability to construct new towers can
be affected by a number of factors beyond its 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. There
can be no assurance that: (i) the Company will be able to overcome the
barriers to new construction; (ii) the number of towers planned for
construction will be completed in accordance with the requirements of the
Company's customers; or (iii) there will be a significant need for the
construction of new towers once the wireless communications carriers complete
their tower network infrastructure build-out. Further, the Company competes
with certain wireless communications carriers, broadcasters, site developers
and other independent tower owners and operators for acquisitions of towers,
and expects such competition to increase. Increased competition for
acquisitions may result in fewer acquisition opportunities for the Company, as
well as higher acquisition prices. The Company regularly explores acquisition
opportunities. However, there can be no assurance that the Company will be
able to identify suitable towers to acquire in the future. In addition, the
Company may need to seek additional debt or equity financing in order to fund
properties it seeks to acquire. The availability of additional financing
cannot be assured and depending on the terms of proposed acquisitions and
financing, could be restricted by the terms of the Company's debt instruments.
No assurance can be given that the Company will be able to identify, finance
and complete future construction and acquisitions on acceptable terms or that
the Company will be able to manage profitably and market under-utilized
capacity on additional towers. The extent to which the Company is unable to
construct or acquire additional towers, or manage profitably such tower
expansion, may have a material adverse effect on the Company's financial
condition and results of operation.

In addition, the time frame for the current wireless build-out cycle may be
limited to the next few years, and many PCS and PCN networks have already been
built out in large markets. A failure by the Company to move quickly and
aggressively to obtain growth capital and capture this infrastructure
opportunity could have a material adverse effect on the Company's financial
condition and results of operations.

<PAGE>

DEPENDENCE ON DEMAND FOR WIRELESS COMMUNICATIONS; RISK ASSOCIATED WITH NEW
TECHNOLOGIES

Demand for the Company's site rentals is dependent on demand for
communication sites from wireless communications carriers, which, in turn, is
dependent 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 extent to which wireless
communications carriers lease such communication sites depends on a number of
factors beyond the Company's control, including the level of demand for such
wireless services, the financial condition and access to capital of such
carriers, the strategy of carriers with respect to owning or leasing
communication sites, government licensing of broadcasting rights, changes in
telecommunications regulations and general economic conditions.

The wireless communications industry has undergone 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, the Company anticipates that a significant
amount of its revenues over the next several years will be generated from
carriers in the PCS and PCN market and, as such, the Company will be subject
to downturns in PCS and PCN demand. Moreover, wireless communications carriers
often operate with substantial leverage, and financial problems for the
Company's 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 the Company's financial condition and results of operations.

VARIABILITY IN DEMAND FOR NETWORK SERVICES

Demand for the Company's 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 communications
carriers' tower build-outs, timing of existing customer contracts and general
economic conditions. While such demand fluctuates, the Company 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 the Company's network services
businesses for any particular period may vary significantly, and should not be
considered as necessarily being indicative of longer-term results. For
example, the Company experienced a decline, as compared to the two previous
quarters, in demand for its network services business in the fourth quarter of
1997 and the first quarter of 1998. There can be no assurance that the demand
for such business will return to the level of the two previous quarters.
Furthermore, as wireless communications 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 the Company's operating performance.

COMPETITION

The Company competes for site rental customers with (i) wireless
communications carriers that own and operate their own tower footprints and
lease, or may in the future decide to lease, antenna space to other carriers,
(ii) site development companies which acquire antenna space on existing towers
for wireless communications carriers and manage new tower construction, (iii)
other independent tower companies and (iv) 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 the Company. The Company believes 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.

The Company competes for acquisition and new tower construction
opportunities with wireless communications carriers, site developers and other
independent tower operators. The Company believes that

21
<PAGE>

competition for tower acquisitions will increase and that additional
competitors will enter the tower market. These additional competitors may have
greater financial resources than the Company.

NTL, which owns the privatized engineering division of the Independent
Broadcasting Authority, is the Company's principal competitor in the
terrestrial broadcast transmission market in the United Kingdom. There can be
no assurance that the Company will not encounter significant competition from
NTL for its transmission business with the BBC or BDB following the expiration
of the Company's current contracts with such broadcasters. See "--Reliance on
Significant Agreements".

RELIANCE ON SIGNIFICANT AGREEMENTS

While the Company generally has a diverse customer base, the BBC, Nextel and
NTL accounted for approximately 45.1%, 7.5% and 6.6%, respectively, of the
Company's pro forma revenues for the six months ended June 30, 1998.

The Company's broadcast transmission business is substantially dependent on
contracts with the BBC. See "Business--U.K. Operations--Significant
Contracts". The prices that the Company may charge the BBC for analog
television and radio transmission services are subject to regulation by the
U.K. Office of Telecommunications ("OFTEL"). See "--Regulatory Compliance and
Approval". The BBC Analog Transmission Contract expires on March 31, 2007, and
the BBC Digital Transmission Contract will expire 12 years after the date on
which the Company commences digital terrestrial transmission services on a
commercial basis for the BBC, which is expected to be November 1, 1998. In
addition, the BBC Digital Transmission Contract may be terminated by the BBC
during the three-month period following the fifth anniversary of the Company's
commencement of digital terrestrial transmission services for the BBC 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. There can be no assurance that the BBC will renew its contracts
with the Company upon expiration of the current contracts, that they will not
negotiate terms less favorable to the Company or that they would not seek to
obtain from third parties a portion of the transmission services currently
provided by the Company. The loss of the BBC contracts would have a material
adverse effect on the Company's business, results of operations and financial
condition.

As of June 30, 1998, the Company had constructed or purchased 88 towers for
Nextel, was in the process of constructing or receiving permits for 30 towers
for Nextel and had the option to construct or purchase up to 108 additional
towers for Nextel. See "Business--U.S. Operations--Significant Contracts".
Nextel may terminate the Nextel Agreement (as defined) if the Company fails to
complete the construction of towers within an agreed period or if Nextel
exercises its purchase option (following certain construction delays by the
Company) for the greater of five towers or 5% of the aggregate number of total
sites committed to within a rolling eight-month period. Furthermore, the
Nextel Agreement may be terminated by Nextel upon either the insolvency or
liquidation of the Company. The Nextel Agreement represents a significant part
of the Company's business strategy, and the Company expects Nextel to
represent an even larger portion of its business in the future. Termination of
the Nextel Agreement could have a material adverse effect on the Company's
ability to achieve its business strategy.

In order to optimize service coverage in the United Kingdom and enable
viewers to receive all analog UHF television services using one receiving
antenna, pursuant to the Site-Sharing Agreement (as defined), CTI and NTL made
arrangements to share all UHF television sites. See "Business--U.K.
Operations--Significant Contracts". Negotiations are in progress between the
Company and NTL 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. The Site-Sharing Agreement may be terminated with five
years' prior notice by either of the parties and in certain other
circumstances and expires on December 31, 2005 or on any tenth anniversary of
that date. Although the Company does not anticipate that the Site-Sharing
Agreement will be terminated, there can be no assurance that such a
termination will not occur. Termination of the Site-Sharing Agreement could
have a material adverse effect on the Company's business, results of
operations and financial condition.

22

REGULATORY COMPLIANCE AND APPROVAL

The Company is subject to a variety of foreign, federal, state and local
regulation. In the United States, both the FCC and the Federal Aviation
Administration (the "FAA") 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. Wireless communications devices
operating on towers are separately regulated and independently licensed based
upon the regulation of the particular frequency used. 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. Owners of towers may have an obligation to paint
them or install lighting to conform to FCC standards and to maintain such
painting or lighting. Tower owners may also bear the responsibility for
notifying the FAA of any tower lighting failures. The Company generally
indemnifies its customers against any failure to comply with applicable
standards. Failure to comply with applicable requirements may lead to civil
penalties or require the Company 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 the Company's ability to respond to customers'
demands. In addition, such regulations increase the costs associated with new
tower construction. There can be no assurance 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 to the Company. Such factors could
have a material adverse effect on the Company's 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. Regulatory approvals required to construct or materially alter
towers include Civil Aviation Authority (the "CAA") approval, to ensure new
antenna structures do not present a hazard to aviation, and local government
planning authority clearance. In addition, international frequency clearance
may be required to avoid any potential European transmission interference.
Such regulation may delay, restrict or prevent such construction or
alteration, thereby limiting the Company's ability to respond to customers'
demands. There can be no assurance 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 to the Company. Such factors could have a material
adverse effect on the Company's financial condition and results of operations.

Since the BBC Analog Transmission Contract was signed, the BBC has increased
its service requirements to include (i) 24-hour broadcasting on the Company's
terrestrial transmission network for the BBC's two national television
services and (ii) 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 ($1,335,600) per year in the charges payable
by the BBC to CTI, as provided under the BBC Analog Transmission Contract, 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 the Company expects the license to be
amended, there can be no assurance as to the final resolution of these issues
with OFTEL.

The Company's customers may also become subject to new regulations or
regulatory policies which adversely affect the demand for communication sites.
In addition, as the Company pursues international opportunities, it will be
subject to regulation in foreign jurisdictions.

23
<PAGE>

The Company is also subject to laws and regulations relating to worker
health and safety. Failure to comply with such laws and regulations could have
a material adverse effect on the Company's business, results of operation, or
financial condition. See "Business--Regulatory Matters".

ENVIRONMENTAL MATTERS

The Company's 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 ("Environmental Laws"). Under
certain Environmental Laws, the Company could be held strictly, jointly and
severally liable for the remediation of hazardous substance contamination at
its current or former facilities or at third-party waste disposal sites, and
also could be subject to personal injury or property damage claims related to
such contamination. Although the Company believes that it is in substantial
compliance with all applicable Environmental Laws, there can be no assurance
that the costs of compliance with existing or future Environmental Laws will
not have a material adverse effect on the Company's financial condition and
results of operations. See "Business--Environmental Matters".

PERCEIVED HEALTH RISKS ASSOCIATED WITH RADIO FREQUENCY EMISSIONS

The Company and the wireless communications carriers that utilize the
Company's towers are subject to government requirements and other guidelines
relating to radio frequency ("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 the Company has not been subject to any claims relating to RF
emissions, there can be no assurance that it will not be subject to such
claims in the future. See "--Environmental Matters" and "Business--
Environmental Matters".

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

The Company conducts business in countries outside the United States, which
exposes the Company to fluctuations in foreign currency exchange rates. In
1997, after giving pro forma effect to the Roll-Up, approximately 68.8% of the
Company's consolidated revenues would have originated outside the United
States, all of which were denominated in currencies other than U.S. dollars
(principally pounds sterling). The Company has not historically engaged in
significant hedging activities with respect to its non-U.S. dollar operations.

The Company's 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. There can be no assurance that these and other factors
will not have a material adverse effect on the Company's financial condition
or results of operations.

DEPENDENCE ON PRINCIPAL EXECUTIVE OFFICERS

The Company's existing operations and continued future development are
dependent to a significant extent upon the performance and the active
participation of certain key individuals, including the senior management of
the Company and its subsidiaries. There can be no assurance that the Company
will be successful in retaining the services of these, or its other, key
personnel. None of the Company's employees are subject to noncompetition
agreements with the Company. The loss of the services of one or more of the
Company's key personnel could adversely affect the Company's financial
condition and results of operations. See "Management--Executive Compensation--
Crown Arrangements".

YEAR 2000 COMPLIANCE

24
<PAGE>

to resolve the issue. The Company expects to incur internal staff costs, as
well as other expenses, related to testing and updating its systems to prepare
for the Year 2000. The Company presently believes that, with modifications and
upgrades to existing software and successful conversion to new software, the
Year 2000 Issue will not pose significant operational problems for the
Company's systems as so modified, upgraded or converted. Although the Company
is in the initial phases of determining the impact of the Year 2000 Issue, the
Company anticipates it will be fully Year 2000 compliant by September 1, 1999;
however, any delays or omissions by the Company or its customers, suppliers or
contractors to resolve the Year 2000 Issue could materially adversely affect
the Company's business, financial condition or results of operations. There
can be no assurance that amounts to be spent on addressing the Year 2000 Issue
will not be material.

ANTI-TAKEOVER PROVISIONS

Certain provisions of the Certificate of Incorporation, the Amended and
Restated Bylaws (the "By-laws") and operative agreements entered into in
connection with the Roll-Up could make it more difficult for a third party to
acquire, and could discourage a third party from attempting to acquire,
control of the Company. These provisions include, but are not limited to, the
right of the holders of the 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 shares of undesignated preferred stock in one or
more series without the specific approval of the holders of Common Stock
(other than the holders of the 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 the Class A Common
Stock approve certain changes to the Certificate of Incorporation or the By-
laws. In addition, the 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, subject to certain conditions, TdF has the right to
purchase the Company's equity interest in CTSH upon the occurrence of a
Triggering Event that is not approved by TdF. In addition, subject to certain
limitations, the BBC Analog Transmission Contract and the BBC Digital
Transmission Contract may be terminated 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 the Company is subject), could impede a merger, consolidation, takeover
or other business combination involving the Company or discourage a potential
acquirer from making a tender offer or otherwise attempting to obtain control
of the Company. In certain circumstances, the fact that corporate devices are
in place that will inhibit or discourage takeover attempts could reduce the
market value of the Common Stock. See "Description of Capital Stock", "--Risks
Related to Agreements with TdF" and "The Roll-Up".

SHARES ELIGIBLE FOR FUTURE SALE

Sales of a substantial number of shares of Common Stock after the Offering
could adversely affect the market price of the Common Stock and could impair
the Company's ability to raise capital through the sale of equity securities.
Upon completion of the Offering, the Company will have 82,548,545 shares of
Common Stock outstanding (82,803,063 shares if the over-allotment option is
exercised in full). In addition, the Company has reserved for issuance
16,182,350 shares of Common Stock upon exercise of outstanding stock options,
1,314,990 shares of Common Stock upon exercise of outstanding warrants and
11,340,000 shares of Common Stock for the conversion of the outstanding Class
A Common Stock. The 14,000,000 shares (16,100,000 if the over-allotment option
is exercised in full) sold in the Offering will be freely transferable without
restriction under the Securities Act, unless they are held by "affiliates" of
the Company as that term is used under the Securities Act. The remaining
68,548,545 shares of Common Stock outstanding (66,703,063 if the over-
allotment option is exercised in full) will be "restricted securities" as that
term is defined in Rule 144 and may only be sold pursuant to a registration
statement under the Securities Act or an applicable exemption from
registration. Approximately 67,000,000 shares (approximately 99,000,000
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 180-day lock-
up period described below, approximately 36,500,000 shares may be sold under
Rule 144, subject to the volume restrictions contained therein.

25
<PAGE>

In connection with the Offering and subject to certain exceptions, the
Company and, with certain limited exceptions, all existing stockholders of the
Company will be required not to sell any shares of Common Stock (including
shares under options and warrants) for a period of 180 days after the date of
this Prospectus without the prior written consent of Lehman Brothers Inc. In
addition to certain typical exceptions to such "lock-up" agreements, all
employees of the Company and its subsidiaries (excluding Mr. Crown, certain
executive officers and the directors of the Company) will each be permitted to
sell during the 180-day period described above up to 12% of the shares of
Common Stock beneficially owned or held under option by such employee as of
the date of this Prospectus, subject to compliance with the registration
requirements of the Securities Act or pursuant to an exemption therefrom. In
addition, the lock-up will not prohibit sales of shares received from the
exercise of options granted under the CTSH All Employee Share Option Scheme,
which options will be fully vested upon consummation of the Offering and which
represent 285,350 shares of Common Stock. Moreover, any shares subject to such
lock-up agreements may be released at any time without notice with the consent
of Lehman Brothers Inc. See "Underwriting".

DILUTION

Persons purchasing shares of Common Stock in the Offering will incur
immediate and substantial dilution in net tangible book value per share.
Purchasers of shares in the Offering will experience dilution of $10.95 per
share. In addition, pursuant to the Governance Agreement, 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 Class A Common Stock (which is
convertible into Common Stock) and warrants for Class A Common Stock (which is
convertible into Common Stock) of the Company. Such exchange would be based on
the Exchange Ratio 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 the Company to
purchase all of TdF's equity interest in CTSH at its fair market value, which
purchase may be made, at the election of the Company, in shares of Common
Stock valued at a discount of 15% to its then current market value. See "--
Risks Related to Agreements with TdF" and "The Roll-Up." If the Company were
to make such an election, it would result in substantial additional dilution.
In addition, to the extent that outstanding options and warrants to purchase
Common Stock are exercised, there could be substantial additional dilution.
See "--Risks Related to Agreements with TdF", "Dilution" and "The Roll-Up".

NO PRIOR MARKET FOR THE COMMON STOCK; POSSIBLE VOLATILITY OF SHARE PRICE

Prior to the Offering, there has been no public market for the Common Stock,
and there can be no assurance that an active trading market will develop upon
completion of the Offering or, if it does develop, that such market will be
sustained. The initial public offering price of the Common Stock will be
determined by negotiation among the Company and the representatives of the
Underwriters, and may not be representative of the price that will prevail in
the open market. See "Underwriting" for a discussion of the factors that were
considered in determining the initial public offering price.

The market price of the Common Stock after the Offering may be significantly
affected by factors such as quarterly variations in the Company's results of
operations, the announcement of new contracts by the Company or its
competitors, technological innovation by the Company or its competitors and
general market conditions specific to particular industries. Such fluctuations
may adversely affect the market price of the Common Stock.

26
<PAGE>

USE OF PROCEEDS

The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $148.0 million, after
deducting estimated underwriting discounts, transaction fees and expenses of
the Offering payable by the Company. The net proceeds to the Company of the
Offering will be used for working capital and general corporate purposes
including (i) acquisitions, investments and joint ventures and (ii) capital
expenditures associated with (a) the buildout of new infrastructure in the
United Kingdom to support DTT and (b) the construction of new towers. Prior to
such application, the net proceeds will be invested in short-term investments.

Due to the number and variability of factors that will be analyzed before
the Company determines how to use the net proceeds of the Offering, the
Company will have broad discretion in allocating a significant portion of such
net proceeds without any action or approval of the Company's stockholders.
While the Company is currently pursuing a number of acquisition opportunities,
the Company has not entered into any agreements in respect of, and believes
that there are a number of competing bidders for, these opportunities. As a
result, the Company does not believe that any of these acquisition
opportunities have become probable. Therefore, none of the net proceeds have
been specifically allocated to any of these opportunities. Accordingly,
investors will not have the opportunity to evaluate the economic, financial
and other relevant information that will be considered by the Company in
determining the application of such net proceeds. See "Risk Factors--Broad
Discretion in Application of Proceeds".

DIVIDEND POLICY

No dividends have ever been paid by the Company on the Common Stock, and the
Company does not anticipate paying dividends in the foreseeable future. Any
determination to pay cash dividends in the future will be at the discretion of
the Company's Board of Directors and will depend upon the Company's results of
operations, financial condition, contractual restrictions and other factors
deemed relevant at that time by the Company's Board of Directors.

The ability of the Company to pay dividends on the Common Stock is dependent
upon the ability of its subsidiaries to pay dividends, or otherwise loan,
advance or transfer funds, to the Company. The terms of the Company's
indebtedness impose limitations on the ability of the Company to pay dividends
or make other distributions on its capital stock. See "Risk Factors--
Substantial Leverage; Restrictions Imposed by the Terms of the Company's
Indebtedness", "Risk Factors--Holding Company Structure; Dependence on
Dividends to Meet Cash Requirements or Pay Dividends" and "Description of
Certain Indebtedness".

<PAGE>

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 Offering. 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.

The net tangible book value of the Company on June 30, 1998, after
subtracting the interests of the preferred shareholders, was a deficit of
approximately $121.6 million or negative $11.10 per share. The net tangible
book value of the Company, after giving effect to the Roll-Up and the Senior
Preferred Conversion, on June 30, 1998 was approximately $44.4 million or
$0.54 per share. After giving effect to the receipt of approximately
$148.0 million of estimated net proceeds from the sale by the Company of
12,320,000 shares of Common Stock pursuant to the Offering, the pro forma net
tangible book value of the Company at June 30, 1998 would have been
approximately $192.4 million or $2.05 per share. This represents an immediate
increase in pro forma net tangible book value of $1.51 per share to the
existing stockholders and an immediate dilution of $10.95 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:

(determined as if the Offering had occurred on June 30, 1998), stockholders
receiving shares in the Roll-Up ("Roll-Up stockholders") (determined as if the
Roll-Up had occurred on June 30, 1998) and new investors with respect to the
number of shares of Common Stock purchased from the Company, the total
consideration paid to the Company and the average price paid per share.

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 "The Roll-Up". The foregoing tables and
discussion assume no exercise of stock options or warrants after June 30, 1998
and exclude (i) 5,280,510 shares issuable upon exercise of stock options
outstanding as of June 30, 1998 having a weighted average exercise price of
$5.58 per share under the Company's 1995 Stock Option Plan, (ii) 12,719,490
additional shares authorized for issuance under the Company's 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 Put Right or the Company 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 the Company to
repurchase the shares of capital stock of CTSH held by TdF at fair market
value. Pursuant to the Governance Agreement, the Company 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--Risks Related to Agreements with TdF" and
"The Roll-Up". If the Company were to issue shares of its Common Stock to
effect the purchase, such issuance would result in substantial dilution to the
Company's other stockholders. Since June 30, 1998, the Company has granted
options to purchase an additional 6,644,480 shares of Common Stock, of which
options for 3,054,480 shares have an exercise price of $7.50 and options for
3,590,000 shares have an exercise price of $13.00. To the extent that
outstanding stock options or warrants are exercised, there will be further
dilution to new investors. See "Risk Factors--Risks Related to Agreements with
TdF", "Risk Factors--Dilution", "Capitalization", "Management--Executive

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 (including TEA and Crown) during the periods
presented, adjusted to give effect to the following transactions
(collectively, the "Transactions"): (i) the CTI Investment, (ii) the TEA
Acquisition, (iii) the acquisition of TeleStructures (the "TeleStructures
Acquisition"), (iv) the Crown Merger (together with the acquisitions described
in clauses (i), (ii) and (iii), the "Acquisitions"), (v) the 1997 Refinancing,
(vi) the Roll-Up, (vii) the Offering and (viii) the Senior Preferred
Conversion.

The Unaudited Pro Forma Condensed Consolidated Statement of Operations for
the year ended December 31, 1997 gives effect to the Transactions as if they
had occurred as of January 1, 1997, and the Unaudited Pro Forma Condensed
Consolidated Statement of Operations for the six months ended June 30, 1998
gives effect to the Roll-Up, the Offering and the Senior Preferred Conversion
as if they had occurred as of January 1, 1998. The Unaudited Pro Forma
Condensed Consolidated Balance Sheet gives effect to the Roll-Up, the Offering
and the Senior Preferred Conversion as if they had occurred as of June 30,
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.

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
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
Prospectus and "Management's Discussion and Analysis of Financial Condition
and Results of Operations".

The Acquisitions and the Roll-Up are accounted for under the purchase method
of accounting. The total purchase price for each Acquisition and the Roll-Up
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 from the Offering.

(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, includes (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".
CCIC expects to record non-cash compensation charges related to the
issuance of stock options to certain employees and executives. Such
charges are expected to amount to $10.6 million in 1998, recognized upon
completion of the Offering, and approximately $1.6 million per year
thereafter through 2003.
(b) 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.
(c) Represents the aggregate number of sites of CCIC as of the end of each
period.
(d) As of June 30, 1998, CCIC had contracts with 1,283 buildings to manage on
behalf of such buildings the leasing of space for antenna 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 June 30,
1998, CCIC had 1,217 rooftop sites under management throughout the United
States that were not revenue producing but were available for leasing to
customers.
(e) EBITDA is defined as operating income (loss) plus depreciation and
amortization. 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.
(f) 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 and 1997 and the six months ended June 30, 1997 and 1998,
earnings were insufficient to cover fixed charges by $21,000, $0.9
million, $10.8 million, $1.9 million and $13.3 million, respectively.
(g) Represents (i) 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 (ii) 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 will be converted into shares of
Common Stock in connection with the Offering.

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, for the three months ended June 30, 1997 and for the nine months ended
December 31, 1997, and (iii) selected historical consolidated financial data
of CTI as of and for the six months ended June 30, 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 three
months ended June 30, 1997 and as of and for the six months ended June 30,
1998 have been derived from the unaudited consolidated financial statements of
CTI, which include all adjustments that CTI considers necessary for a fair

three months ended June 30, 1997, the nine months ended December 31, 1997 and
the six months ended June 30, 1998 are not necessarily indicative of the
results of operations of CTI that may be expected for the entire year. 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--Holding Company Structure; Dependence on Dividends to Meet Cash
Requirements or Pay Dividends". The information set forth below should be read

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 (i) CCIC's consolidated financial condition as of June 30, 1998
and its consolidated results of operations for the six-month periods ended
June 30, 1997 and 1998 and for each year in the three-year period ended
December 31, 1997 and (ii) CTI's consolidated results of operations for the
three-month periods ended June 30, 1997 and 1998 and 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
capital expenditures decisions to be made in the future by wireless
communications 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 Crown", "Selected Financial and Other Data of CTI" and the
consolidated financial statements and the notes thereto included elsewhere in
this Prospectus. Results of operations of the acquired businesses which are
wholly 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 six months ended June 30, 1997 are
not comparable to the results of operations for the six months ended June 30,
1998, and the results for the year ended December 31, 1996 are not comparable
to the year ended December 31, 1997.

OVERVIEW

Following consummation of the Roll-Up, the continued growth of the Company's
business will depend 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 communications carriers will continue to seek
operating and capital efficiencies by (i) outsourcing certain network services
and the build-out and operation of new and existing infrastructure and (ii)
co-locating antennas and transmission equipment on multiple tenant towers. In
addition, the Company expects that, in order to free up capital for the growth
and management of their customer bases and expansion of their service
offerings, wireless communications carriers have begun 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 communications carriers and
broadcasters ultimately will seek to outsource the operation of their towers
and 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 communications 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 commencement 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 to broadcasters, zoning
restrictions on tall towers and the cost of building towers.

As an important part of its business strategy, the Company will continue (i)
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, (ii) to leverage its in-house technical and operational expertise,
(iii) to expand its tower footprints by partnering with wireless
communications carriers to assume ownership of their existing towers and by
pursuing build-to-suit opportunities and (iv) to acquire existing transmission
networks globally as opportunities arise.

RESULTS OF OPERATIONS

CCIC

CCIC's primary sources of revenues are from (i) the rental of antenna space
on towers and rooftop sites and (ii) 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 monthly site rental revenues per
owned site as of December 31, 1997 were approximately $3,000 for the towers
located in the southwestern United States, $7,000 for the towers in Puerto
Rico, $12,500 for the towers in and around the greater Pittsburgh area, and
$2,000 for CCIC's other revenue producing towers. 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 (i) network design and
site selection, (ii) site acquisition, (iii) site development and
construction, (iv) antenna installation and (v) 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". 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. Average monthly revenues as of December 31, 1997 from SMR and
microwave services were approximately $77,000 and $12,000, respectively.

Costs of operations for site rental primarily consist of land leases,
repairs and maintenance, utilities, insurance, property taxes and monitoring
costs and, 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 (i) to support its internal operations, including construction and
maintenance of its owned towers, and (ii) 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 provide the type of end-to-end services that enhance its ability
to acquire access to the infrastructure of wireless communications 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

43
<PAGE>

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.

The following information is derived from CCIC's Historical Consolidated
Statements of Operations for the periods indicated.

Comparison of Six Months Ended June 30, 1998 and 1997

Consolidated revenues for the six months ended June 30, 1998 were $23.4
million, an increase of $16.6 million from the six months ended June 30, 1997.
This increase was primarily attributable to (i) a $7.1 million, or 212.7%,
increase in site rental revenues which was primarily attributable to the Crown
operations; (ii) $0.9 million in network services revenues from TEA; and (iii)
$6.8 million in network services revenues from the Crown operations.

Costs of operations for the six months ended June 30, 1998 were $9.6
million, an increase of $6.8 million from the six months ended June 30, 1997.
This increase was primarily attributable to (i) $0.4 million of network
services costs related to the TEA operations; (ii) $3.7 million of network
services costs related to the Crown operations; and (iii) $1.8 million in site
rental costs attributable to the Crown operations. Costs of operations for
site rental as a percentage of site rental revenues increased to 23.1% for the
six months ended June 30, 1998

44
<PAGE>

from 18.1% for the six months ended June 30, 1997 because of higher costs
attributable to the Crown operations. Costs of operations for network services
as a percentage of network services revenues decreased to 55.4% for the six
months ended June 30, 1998 from 63.4% for the six months ended June 30, 1997,
reflecting higher margins that are inherent in the network services business
acquired with the Crown operations in August 1997 as compared to that acquired
with the TEA operations in May 1997.

General and administrative expenses for the six months ended June 30, 1998
were $8.8 million, an increase of $7.3 million from the six months ended June
30, 1997. This increase was primarily attributable to $4.9 million of expenses
related to the Crown operations and $0.8 million of expenses related to the
TEA operations, along with an increase in costs of $1.3 million at the
Company's corporate office. General and administrative expenses as a
percentage of revenues increased for the six months ended June 30, 1998 to
37.5% from 22.0% for the six months ended June 30, 1997 because of higher
overhead costs as a percentage of revenues for Crown and the increase in costs
at CCIC's corporate office.

Corporate development expenses for the six months ended June 30, 1998 were
$2.0 million, a decrease of $1.8 million from the six months ended June 30,
1997. Corporate development expenses for the six months ended June 30, 1997
include nonrecurring compensation charges associated with the CTI Investment
of (i) $0.9 million for certain executive bonuses and (ii) 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. Corporate development
expenses for the six months ended June 30, 1998 include discretionary bonuses
related to CCIC's performance totaling approximately $0.8 million for certain
members of CCIC's management. CCIC expects to record non-cash compensation
charges related to the issuance of stock options to certain employees and
executives. Such charges are expected to amount to $10.6 million in 1998,
recognized upon completion of the Offering, and approximately $1.6 million per
year thereafter through 2003. See "--Compensation Charges Related to Stock
Option Grants".

Depreciation and amortization for the six months ended June 30, 1998 was
$7.7 million, an increase of $6.8 million from the six months ended June 30,
1997. This increase was primarily attributable to (i) $6.2 million of
depreciation and amortization related to the property and equipment, goodwill
and other intangible assets acquired in the Crown Merger; and (ii) $0.3
million of depreciation and amortization related to the property and equipment
and goodwill acquired in the TEA and TeleStructures Acquisitions.

The equity in earnings (losses) of unconsolidated affiliate represents
CCIC's 34.3% share of CTI's net earnings (losses) for the periods beginning in
March 1997. For the six months ended June 30, 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 $71.8 million, $11.2 million,
$10.3 million and $1.5 million, respectively. Included in CTI's results of
operations for such period are noncash compensation charges for approximately
$3.2 million related to the issuance of stock options to certain members of
CTI's management. If successful, the consummation of a share exchange
agreement with certain shareholders of CTI would accelerate the vesting of
certain options granted to CTI's management and employees, resulting in
additional noncash compensation charges of approximately $0.7 million.

Interest and other income for the six months ended June 30, 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 the six months ended June 30, 1998 resulted primarily from the
investment of excess proceeds from the sale of CCIC's 10 5/8% Senior Discount
Notes due 2007 in November 1997.

Interest expense and amortization of deferred financing costs for the six
months ended June 30, 1998 was $10.0 million, an increase of $8.8 million, or
738.4%, from the six months ended June 30, 1997. This increase was primarily
attributable to amortization of the original issue discount on the Notes.

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 (i) a $5.4
million, or 96.1%, increase in site rental revenues, of which $4.2 million

45
<PAGE>

was attributable to the Crown operations and $0.7 million was attributable to
the Puerto Rico operations; (ii) $10.4 million in network services revenues
from TEA; and (iii) $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.

Costs of operations for 1997 were $15.4 million, an increase of $14.1
million from 1996. This increase was primarily attributable to (i) $8.5
million of network services costs related to the TEA operations; (ii) $3.9
million of network services costs related to the Crown operations; and (iii)
$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 (i) $0.9 million for certain executive bonuses and (ii) 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 (i) $4.7
million of depreciation and amortization related to the property and
equipment, goodwill and other intangible assets acquired in the Crown Merger;
(ii) $0.5 million of depreciation and amortization related to the property and
equipment and goodwill acquired in the TEA and TeleStructures Acquisitions;
and (iii) $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 (i) commitment fees related to an unfunded
interim loan facility related to the Crown Merger and an unfunded revolving
credit facility; (ii) interest on notes payable to the former stockholders of
Crown for a portion of the purchase price of the Crown Business; (iii)
amortization of the original issue discount on the Notes; (iv) interest and
fees associated with borrowings

46
<PAGE>

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

Comparison of Years Ended December 31, 1996 and 1995

Consolidated revenues for 1996 were $6.2 million, an increase of $2.1
million, or 53.0%, from 1995. This increase was primarily attributable to (i)
$0.6 million in site rental revenues attributable to the Puerto Rico
operations; (ii) $0.6 million in site rental revenues resulting from the
effect of a full year's activity for the operations of Spectrum (which was
acquired in October 1995); (iii) an increase in site rental revenues of $0.3
million, or 6.9%, from the towers acquired from PCI; and (iv) $0.5 million in
SMR and microwave radio services revenues attributable to the Puerto Rico
operations.

Costs of operations for 1996 were $1.3 million, an increase of $0.1 million,
or 6.0%, from 1995. Additional costs in 1996 of $0.3 million attributable to
the Puerto Rico operations were largely offset by decreased costs of $0.2
million associated with the towers acquired from PCI. Such towers were managed
by PCI during 1995 under an agreement with CCIC, and the management fees
charged to CCIC amounted to $0.6 million. CCIC began managing the towers on
January 1, 1996. As a result of these factors, costs of operations as a
percentage of revenues decreased to 21.0% in 1996 from 30.2% in 1995.

General and administrative expenses for 1996 were $1.7 million, an increase
of $0.9 million from 1995. This increase was primarily attributable to costs
of $0.5 million and $0.1 million associated with the Spectrum and Puerto Rico
Acquisitions, respectively, along with an increase in costs of $0.3 million,
or 41.7%, at CCIC's corporate office. General and administrative expenses at
CCIC's corporate office increased because of additional personnel costs and
higher overhead resulting from CCIC's internal management of the PCI towers
beginning in 1996. As a result of these factors, general and administrative
expenses as a percentage of revenues increased to 27.0% in 1996 from 18.0% in
1995.

Corporate development expenses for 1996 were $1.3 million, an increase of
$1.1 million from 1995. This increase was primarily 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
during the last half of 1996.

Depreciation and amortization for 1996 was $1.2 million, an increase of $0.4
million from 1995. This increase was primarily associated with depreciation
associated with towers purchased in the Puerto Rico Acquisition and goodwill
created in the Spectrum Acquisition.

Interest and other income for 1996 was $0.2 million, an increase of $0.1
million from 1995, primarily resulting from the investment of excess proceeds
from the sale of CCIC's Series B Convertible Preferred Stock in July 1996.
Interest expense and amortization of deferred financing costs for 1996 were
$1.8 million, an increase of $0.7 million, or 58.6%, from 1995, primarily
resulting from borrowings under CCIC's bank credit agreement which were used
to finance the Puerto Rico Acquisition.

CTI

CTI's primary sources of revenues are from (i) the provision of analog and
digital broadcast transmission services to the BBC and commercial
broadcasters, (ii) the rental of antenna space on towers and (iii) 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 of
approximately $6.9 million (as of June 30, 1998) are received from the BBC
under a contract with an initial 10-year term through March 31, 2007.
Additional monthly analog revenues of $0.1 million per station (as of June 30,
1998) are received from two national commercial radio stations under contracts
with eight year terms that commenced on March 31, 1993 and February 4, 1995,
respectively. Digital

47
<PAGE>

transmission services revenues from the BBC and BDB are recognized under
contracts with initial terms of 12 years from the date on which the Company
commences digital terrestrial transmission services for the BBC and BDB,
respectively. Monthly revenues from these digital transmission contracts
increase over time as the network rollout progresses, with monthly revenues as
of June 30, 1998 of approximately $0.5 million and $0.4 million from the BBC
and BDB, respectively. 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).
Currently, approximately 200 companies rent space on approximately 405 of
CTI's 808 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. Monthly revenues from CTI's largest
site rental customer, NTL, were (Pounds)551,000 ($923,752) as of June 30,
1998. 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 (i) network design and site selection,
site acquisition, site development and antenna installation (collectively,
"network design and development") and (ii) site management and other services.
Network design and development services are provided to (i) a number of
broadcasting and related organizations, both in the United Kingdom and other
countries; (ii) all four U.K. cellular operators; and (iii) 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.

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

<PAGE>

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, as well as an analysis of results for the three-month periods
ended June 30, 1997 and 1998. 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 and the three months ended June 30, 1997 and 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 average exchange rates for
such periods ranged from (Pounds)1.00 = $1.5841 to (Pounds)1.00 = $1.6605. In
addition, the following amounts reflect certain adjustments to present the
results of operations in accordance with generally accepted accounting
principles ("GAAP") of the U.S. For the results of the BBC Home Service
Transmission Business, such adjustments effect depreciation and amortization
expense as a result of differences in the carrying amounts for property and
equipment; for CTI, such adjustments effect (i) operating expenses as a result
of differences in the accounting for pension costs, and (ii) interest expense
as a result of the capitalization of interest costs in connection with
constructed assets.

Comparison of Three Months Ended June 30, 1998 and Three Months Ended June
30, 1997

Consolidated revenues for the three months ended June 30, 1998 were $37.6
million, an increase of $7.2 million from the three months ended June 30,
1997. This increase was primarily attributable to (i) a $4.6 million increase
in broadcast transmission services and site rental revenues and (ii) a $2.6
million increase in network services and other revenues. Revenues from the BBC
for the three months ended June 30, 1998 amounted to $21.8 million, or 57.8%
of total revenues, as compared to $19.6 million, or 64.5% of total revenues,
for the three months ended June 30, 1997. Revenues from NTL for the three
months ended June 30, 1998 amounted to $3.2 million, or 8.6% of total
revenues. Network services revenues for the three months ended June 30, 1998
consisted of $4.5 million from network design and development services and
$1.5 million from site management and other services.

Costs of operations for the three months ended June 30, 1998 were $18.6
million, an increase of $4.0 million from the three months ended June 30,
1997. This increase was primarily attributable to a $1.1 million increase in
broadcast transmission services and site rental costs and a $2.9 million
increase in network services and other costs. Costs of operations as a
percentage of revenues for broadcast transmission services and site rental
were 46.3% for the three months ended June 30, 1998, as compared to 50.1% for
the three months ended June 30, 1997. This decrease was attributable to
increases in site rental revenues from existing sites with little change in
site operating costs. Costs of operations as a percentage of revenues for
network services and other were 66.0% for the three months ended June 30,
1998, as compared to 32.4% for the three months ended June 30, 1997. This
increase was attributable to high profit margins recognized for a consulting
contract during the three months ended June 30, 1997. Costs of operations for
site rental and broadcast transmission for the three months ended June 30,
1998 includes non-cash compensation charges for $0.3 million related to the
issuance of stock options to certain employees.

General and administrative expenses for the three months ended June 30, 1998
were $2.4 million, an increase of $0.2 million from the three months ended
June 30, 1997. As a percentage of revenues, general and administrative
expenses were 6.3% and 7.3% for the three months ended June 30, 1998 and 1997,
respectively.

Corporate development expenses for the three months ended June 30, 1998
relate primarily to costs incurred in connection with certain projects in
Australasia.

Depreciation and amortization for the three months ended June 30, 1998 was
$9.6 million, an increase of $0.5 million from the three months ended June 30,
1997. This increase resulted from capital expenditures for the period from
June 30, 1997 through June 30, 1998.

Interest and other income for the three months ended June 30, 1998 and 1997
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 three
months ended June 30, 1998 was $5.1 million. This amount was comprised of (i)
$0.3 million related to amounts drawn under the CTI Credit Facility; (ii) $4.6
million related to the CTI Bonds; and (iii) $0.2 million for the amortization
of deferred financing costs. Interest expense and amortization of deferred
financing costs for the three months ended June 30, 1997 was $8.5 million.
This amount was comprised of (i) $3.2 million related to amounts drawn under
the CTI Credit Facility; (ii) $2.0 million related to the CTI Bonds; and (iii)
$3.3 million for the amortization of deferred financing costs.

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 (i) a $1.4 million increase
in broadcast transmission services and site rental revenues and (ii) a $3.6
million increase in network services and other revenues. Revenues from the BBC
for the twelve months ended March 31, 1998

50
<PAGE>

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 twelve months ended March 31, 1998, as compared to
54.7% for the twelve months ended March 31, 1997. This decrease was
attributable to (i) increases in site rental revenues from existing sites with
little change in site operating costs; and (ii) 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 (i) a higher proportion of broadcast
consulting revenues, which result in higher margins than certain other network
design and development services and (ii) 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
(i) $4.9 million related to amounts drawn under the CTI Credit Facility; (ii)
$15.6 million related to the CTI Bonds; and (iii) $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

As of June 30, 1998, after giving pro forma effect to the Roll-Up, the
Offering and the Senior Preferred Conversion, the Company would have had
consolidated cash and cash equivalents of $215.1 million (including

51
<PAGE>

$15.8 million at CTI), consolidated long-term debt of $465.3 million and
consolidated stockholders' equity of $758.3 million.

The Company's business strategy contemplates substantial capital
expenditures in connection with (i) the expansion of its tower footprints by
partnering with wireless communications carriers to assume ownership of their
existing towers and by pursuing build-to-suit opportunities and (ii) to
acquire existing transmission networks globally as opportunities arise. The
exact amount of such capital expenditures will depend on the number of such
opportunities that the Company is able to successfully consummate. The Company
is currently pursuing potential significant acquisitions, investments and
joint venture opportunities that could require the Company to use all of the
proceeds of the Offering and its existing cash on hand prior to the end of
1998. In connection with a site marketing agreement recently entered into
between the Company and BellSouth Mobility, the Company and BellSouth have
agreed to explore future arrangements relating to the ownership, utilization
and management of BellSouth's tower sites throughout the United States. The
Company is also intending to submit a bid in connection with an auction by a
major Regional Bell Operating Company of its U.S. wireless communications
infrastructure. Similarly, the Company has bid on the tower assets, which
encompass more than 250 U.S. tower sites, currently being auctioned by
Vanguard Cellular. In addition to these U.S. opportunities, the Company is
pursuing acquisition opportunities in Australia and New Zealand, including in
certain instances together with other partners. For example, the Company,
together with Fay Richwhite & Company Limited and Berkshire Partners LLC, has
submitted a bid in respect of a wireless communications network, including its
tower infrastructure and radio frequency spectrum. If the bid is successful
and the transaction is consummated, the Company anticipates that it would
invest up to approximately $50.0 million for a substantial minority interest
in the acquired business. The Company is also pursuing acquisition
opportunities in connection with privatizations of state-owned networks. Any
of the foregoing could result in an agreement with respect to a significant
acquisition, investment or joint venture in the near term. However, the
Company has not entered into any agreements in respect of, and believes that
there are a number of competing bidders for, these opportunities. As a result,
the Company does not believe that any of these acquisition opportunities have
become probable. Therefore, there can be no assurance that the Company will
consummate any of the foregoing transactions in the near term or at all. See
"Risk Factors--Broad Discretion in Application of Proceeds" and "Managing
Integration and Growth".

In addition, the Company anticipates that it will build or acquire, through
the end of 1999, approximately 1,000 towers in the United States at a cost of
approximately $237.0 million and approximately 300 towers in the United
Kingdom at a cost of approximately $33.5 million. The Company also expects
that the capital expenditure requirements related to the rollout of digital
broadcast transmission in the United Kingdom will be approximately
(Pounds)110.0 million ($183.6 million).

To fund the execution of the Company's business strategy, the Company and
its subsidiaries expect to use the net proceeds of the Offering, the
borrowings available under the Senior Credit Facility, the borrowings
available under the CTI Credit Facility and the remaining net proceeds from
the 1997 Notes Offering. Whether the Company utilizes the Senior Credit
Facility and the CTI Credit Facility to finance expansion opportunities will
depend upon a number of factors, including (i) the attractiveness of the
opportunities, (ii) the time frame in which they are identified, (iii) the
number of pre-existing projects to which the Company is committed and (iv) the
Company's liquidity at the time of any potential opportunity. In the event the
Company does not otherwise have cash available (from the net proceeds of the
1997 Notes Offering, the net proceeds of the Offering or otherwise), or
borrowings under the Senior Credit Facility or the CTI Credit Facility have
otherwise been utilized, when an opportunity arises, the Company would be
forced to seek additional debt or equity financing or to forego the
opportunity. In the event the Company determines 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 the Company's existing indebtedness. To the extent the Company is
unable to finance future capital expenditures, it will be unable to achieve
its currently contemplated business strategy.

For the years ended December 31, 1995, 1996 and 1997, and for the six months
ended June 30, 1998, CCIC's net cash provided by (used for) operating
activities was $1.7 million, ($0.5 million), ($0.6 million) and

52
<PAGE>

($2.0 million), respectively. Since its inception, CCIC has generally funded
its activities (other than its acquisitions and investments) through excess
proceeds from contributions of equity capital. CCIC has financed its
acquisitions and investments with the proceeds from equity contributions,
borrowings under the Senior Credit Facility and the issuance of promissory
notes to sellers. For the ten months ended December 31, 1997 and for the six
months ended June 30, 1998, CTI's net cash provided by operating activities
was $50.8 million and $32.2 million, respectively. 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 the CTI Credit Facility. CTI financed the acquisition of the
BBC Home Service Transmission Business with the proceeds from equity
contributions and the issuance of the CTI Bonds.

On a pro forma basis, capital expenditures (excluding acquisitions) were
$56.5 million for the year ended December 31, 1997 (of which $3.4 million was
for CCIC and TEA, $27.1 million was for Crown and $26.0 million was for CTI)
and $91.3 million for the six months ended June 30, 1998 (of which $1.5
million was for CCIC, $51.3 million was for Crown and $38.5 million was for
CTI).

In August and October of 1997, CCIC issued shares of its Senior Convertible
Preferred Stock for aggregate net proceeds of $29.3 million and $36.5 million,
respectively. The proceeds from the August issuance were used to make a $25.0
million payment as part of the cash purchase price for the Crown Merger. On
October 31, 1997, the Company entered into an amendment to the Senior Credit
Facility. As amended, the Senior Credit Facility provides for available
borrowings of $100.0 million and expires on December 31, 2004. On October 31,
1997, in connection with the October Refinancing, new borrowings under the
Senior Credit Facility of $94.7 million, along with the proceeds from the
October issuance of the Senior Convertible Preferred Stock, were used to repay
the seller note issued in connection with the Crown Merger, to repay loans
outstanding under a credit agreement at CCI and to pay related fees and
expenses. The Senior Credit Facility requires the Company to maintain certain
financial covenants and places restrictions on the ability of the Company and
its subsidiaries to, among other things, incur debt and liens, pay dividends,
make capital expenditures, undertake transactions with affiliates and make
investments.

CCIC used the net proceeds from the 1997 Notes Offering to repay
substantially all of its outstanding indebtedness, including borrowings under
the Senior Credit Facility, and to pay related fees and expenses. The balance
of the net proceeds from the 1997 Notes Offering is being used for general
corporate purposes. As of August 1, 1998, CCIC's subsidiaries had unused
borrowing availability under the Senior Credit Facility of approximately $25.0
million.

On February 28, 1997, CTI used the proceeds from equity contributions and
borrowings under the CTI Credit Facility to finance the acquisition of the BBC
Home Service Transmission Business. On May 21, 1997, CTI used the net proceeds
from the sale of the CTI Bonds to repay substantially all of the outstanding
borrowings under the CTI Credit Facility. As of June 30, 1998, CTI had unused
borrowing availability under the CTI Credit Facility of approximately
(Pounds)35.0 million ($58.4 million). The CTI Credit Facility requires CTI to
maintain certain financial covenants and places restrictions on the ability of
CTI to, among other things, incur debt and liens, pay dividends, make capital
distributions, make acquisitions, undertake transactions with affiliates and
make investments. 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.

Prior to May 15, 2003, CCIC's interest expense on the Notes will be
comprised solely of the accretion of original issue discount. Thereafter, the
Notes will require annual cash interest payments of approximately
$26.7 million. In addition, the Senior Credit Facility, the CTI Credit
Facility and the CTI Bonds will require periodic interest payments on amounts
borrowed thereunder. The Company's ability to make scheduled payments of
principal of, or to pay interest on, its debt obligations, and its ability to
refinance any such debt obligations (including the Notes and the CTI Bonds),
will depend on its future performance, which, to a certain extent, is subject
to general economic, financial, competitive, legislative, regulatory and other
factors that are beyond its control. As discussed above, the Company's
business strategy contemplates substantial acquisitions and capital

53
<PAGE>

expenditures in connection with the expansion of its tower footprints. There
can be no assurance that the Company will generate sufficient cash flow from
operations in the future, that anticipated revenue growth will be realized or
that future borrowings, equity contributions or loans from affiliates will be
available in an amount sufficient to service its indebtedness and make
anticipated capital expenditures. The Company anticipates that it may need to
refinance all or a portion of its indebtedness (including the Notes and the
CTI Bonds) on or prior to its scheduled maturity. There can be no assurance
that the Company will be able to effect any required refinancings of its
indebtedness (including the Notes and the CTI Bonds) on commercially
reasonable terms or at all. See "Risk Factors".

INFLATION

Because of the relatively low levels of inflation experienced in 1995, 1996
and 1997, inflation did not have a significant effect on CCIC's, Crown's or
CTI's results in such years.

COMPENSATION CHARGES RELATED TO STOCK OPTION GRANTS

During the period from April 24, 1998 through July 15, 1998, CCIC 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 will vest upon consummation of the Offering 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, CCIC 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 an expected
director nominee) 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 and at prices
substantially below the expected price to the public in the Offering, CCIC
will record 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 Offering. Such compensation charge will
total approximately $18.4 million, of which approximately $10.6 million will
be recognized upon consummation of the Offering (for such options and shares
which vest upon consummation of the Offering), and the remaining $7.8 million
will be recognized over five years (approximately $1.6 million per year)
through the second quarter of 2003.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In February 1997, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards No. 128, Earnings per Share
("SFAS 128"). SFAS 128 establishes new standards for computing and presenting
earnings per share ("EPS") amounts for companies with publicly held common
stock or potential common stock. The new standards require the presentation of
both basic and diluted EPS amounts for companies with complex capital
structures. Basic EPS is computed by dividing income available to common
stockholders by the weighted-average number of common shares outstanding for
the period, and excludes the effect of potentially dilutive securities (such
as options, warrants and convertible securities) which are convertible into
common stock. Dilutive EPS reflects the potential dilution from such
convertible securities. SFAS 128 is effective for periods ending after
December 15, 1997. The Company has adopted the requirements of SFAS 128 in its
financial statements for the year ended December 31, 1997.

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 the three months ended March 31, 1998.

54
<PAGE>

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 will adopt the requirements of SFAS 131 in its financial
statements for the year ending December 31, 1998.

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 ended
March 31, 1999; it is currently estimated that such charge will amount to
approximately $2,000,000.

YEAR 2000 COMPLIANCE

The Company is in the process of conducting a comprehensive review of its
computer systems to identify which of its systems will have to be modified,
upgraded or converted to recognize and process dates after December 31, 1999
(the "Year 2000 Issue"), and is in the initial stages of developing an
implementation plan to resolve the issue. The Company expects to incur
internal staff costs, as well as other expenses, related to testing and
updating its systems to prepare for the Year 2000. The Company presently
believes that, with modifications and upgrades to existing software and
successful conversion to new software, the Year 2000 Issue will not pose
significant operational problems for the Company's systems as so modified,
upgraded or converted. Although the Company is in the initial phases of
determining the impact of the Year 2000 Issue, the Company anticipates it will
be fully Year 2000 compliant by September 1, 1999; however, any delays or
omissions by the Company or its customers, suppliers or contractors to resolve
the Year 2000 Issue could materially adversely affect the Company's business,
financial condition or results of operations. There can be no assurance that
amounts to be spent on addressing the Year 2000 Issue will not be material.

INDUSTRY BACKGROUND

GENERAL

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 PCS and PCN. 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 communications 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 communications
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. 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 with digital transmission expected
to commence on a commercial basis in late 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
communications 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. 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 communications 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
communications 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 communications 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 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

57
<PAGE>

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 communications 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 buildout, 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 communications 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
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

58
<PAGE>

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, SMR and ESMR. 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 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 ESMR, 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 ESMR 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
December 31, 1997, there were 51,600 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,
ESMR 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

59
<PAGE>

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. 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 buildout. 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 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

60
<PAGE>

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: (i) greater number, choice and flexibility of broadcasting services
offered; (ii) scope for greater interactivity on the part of viewers and
listeners; (iii) greater capacity for pay-television (subscription and pay-
per-view) as well as free-to-air services; and (iv) 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 communications 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 buildout of new tower infrastructure. The Company believes that
these circumstances, along with the relative scarcity of suitable sites and
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 will be launched in 1998
from terrestrial transmitters (DTT), satellite (DST) and cable (DCT). 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 recently awarded to BDB (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 BDB, while NTL has been
awarded the digital transmission contract for the other two multiplexes.

61
<PAGE>

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 National Radio ("INR") and Independent
Local Radio licenses for additional digital radio multiplexes are expected to
be issued by the end of 1998.

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 accomodate the growth in
digital radio at minimum cost.

BUSINESS

The Company is a leading U.S. and international provider of wireless
communications and broadcast transmission infrastructure and related services.
The Company owns, operates and manages towers, rooftop sites and broadcast
transmission networks, and provides a full range of complementary services
including network design and site selection, site acquisition, site
development and construction, antenna installation and network management and
maintenance. The Company has 19 years of experience in the ownership, leasing
and management of wireless communications sites and a 75-year history of
broadcast transmission and network management. Based on its industry position
and experience, the Company believes it is positioned to capitalize on global
growth opportunities arising from (i) the expansion of existing networks and
the introduction of new networks in the wireless communications industry, (ii)
the consolidation of tower ownership generally, including the transfer of
infrastructure ownership from major wireless communications carriers to
independent infrastructure providers, (iii) the ongoing privatization of
state-run broadcast transmission networks around the world and (iv) the
widespread introduction of digital transmission technology in the broadcasting
industry. For the year ended December 31, 1997 and the six months ended June
30, 1998, the Company had pro forma revenues of $180.9 million and $95.0
million, respectively.

The Company's site rental business involves leasing antenna space to
customers on its owned and managed towers and rooftop sites. The Company
generally receives fees for installing a customer's equipment and antennas on
a tower and also receives monthly rental payments from customers under site
leases that typically range in term from three to five years. The Company's
major site rental customers include Aerial Communications, AT&T Wireless, Bell
Atlantic Mobile, BellSouth Mobility, Motorola, Nextel, PageNet, Sprint PCS and
TSR Wireless in the United States and Cellnet, National Transcommunications
Limited, One2One, Orange Personal Communications and Vodafone in the United
Kingdom.

The Company's broadcast transmission business includes both the transmission
of analog and digital television and radio broadcasts and the construction of
new multiple tenant broadcast towers. In the United Kingdom, the Company
provides analog transmission services for two national television services,
seven national radio services and 37 local radio stations through its network
of 3,465 transmitters. These services are provided under long-term contracts
with the BBC and two national commercial radio companies. In addition, the
Company has long-term contracts to provide digital transmission services to
the BBC and BDB, which together are the holders of four of the six multiplexes
for digital terrestrial television broadcasting throughout the United Kingdom.
In the United States, the Company plans to build new multiple tenant broadcast
towers in locations where additional tower capacity is required to accommodate
digital transmission equipment and analog transmission equipment displaced
from existing towers.

The Company has developed, maintains and deploys primarily for its own use
extensive wireless communications and broadcast transmission network design
and radio frequency engineering expertise, as well as site acquisition, site
development and construction and antenna installation capabilities. The
Company has a team of over 300 engineers with state-of-the-art wireless
communications and broadcast transmission network design and radio frequency
engineering expertise. The Company plans to leverage its technical expertise
and operational experience to enter into build-to-suit and purchase contracts
with, and to enter into joint ventures to own and operate the wireless
communications infrastructure of, various wireless communications carriers
around the world. The Company believes the primary criteria of such carriers
in selecting a company to construct, own or operate their wireless
communications infrastructure will be the company's capability to maintain the
integrity of their networks, including their transmission signals. Therefore,
the Company believes 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.

leasing to customers. The Company's major tower footprints consist of 754
owned and managed towers located across the United Kingdom, 207 owned and
managed towers located in western Pennsylvania (primarily in and around the
greater Pittsburgh area), 185 owned and managed towers located in the
southwestern United States (primarily in Texas), 14 owned towers located on
mountaintops across Puerto Rico and 22 towers along I-95 in North Carolina and
South Carolina. In addition, the Company is currently constructing 55 new
towers on existing sites and has 38 site acquisition projects in process for
sites for its own use.

The Company is actively seeking opportunities for strategic acquisitions of
communications sites and transmission networks and is currently pursuing a
number of potential significant acquisitions, investments and joint venture
opportunities. In connection with a site marketing agreement recently entered
into between the Company and BellSouth Mobility, the Company and BellSouth
have agreed to explore future arrangements relating to the ownership,
utilization and management of BellSouth's tower sites throughout the United
States. The Company is also intending to submit a bid in connection with an
auction by a major Regional Bell Operating Company of its U.S. wireless
communications infrastructure. Similarly, the Company has bid on the tower
assets, which encompass more than 250 U.S. tower sites, currently being
auctioned by Vanguard Cellular. In addition to these U.S. opportunities, the
Company is pursuing acquisition opportunities in Australia and New Zealand,
including in certain instances together with other partners. For example, the
Company, together with Fay Richwhite & Company Limited and Berkshire Partners
LLC, has submitted a bid in respect of a wireless communications network,
including its tower infrastructure and radio frequency spectrum. If the bid is
successful and the transaction is consummated, the Company anticipates that it
would invest up to approximately $50.0 million for a substantial minority
interest in the acquired business. The Company is also pursuing acquisition
opportunities in connection with privatizations of state-owned networks. Any
of the foregoing could result in an agreement with respect to a significant
acquisition, investment or joint venture in the near term. However, the
Company has not entered into any agreements in respect of, and believes that
there are a number of competing bidders for, these opportunities. As a result,
the Company does not believe that any of these acquisition opportunities have
become probable. Therefore, there can be no assurance that the Company will
consummate any of the foregoing transactions in the near term or at all. See
"Risk Factors--Broad Discretion in Application of Proceeds" and "Risk
Factors--Managing Integration and Growth".

BACKGROUND

Founded in 1994, the Company acquired 127 towers located in Texas, Colorado,
New Mexico, Arizona, Oklahoma and Nevada from PCI in 1995. Also in 1995, in
order to expand its geographic coverage, scope of services and client base,
the Company consummated the Spectrum Acquisition for a leading rooftop
management and engineering firm that manages rooftop sites. The Spectrum
Acquisition provided the Company with management revenues for 44 rooftop
sites, as well as important relationships with carriers, and gave the Company
an entry into the market for wireless network services.

In 1996, the Company acquired from Motorola a strategic cluster of 14 towers
located on mountaintops across Puerto Rico, as well as one rooftop site and an
island-wide microwave and SMR system. The Puerto Rico Acquisition gave the
Company a strategic tower footprint, and positioned the Company to be a
leading independent tower operator in the Puerto Rican market. In addition, in
July 1996, CCIC purchased an option to acquire 36% of TEA, which represented a
significant step for the Company towards becoming a full service provider of
wireless network services. TEA is a leading site acquisition firm offering
carriers specialized expertise in site selection, site acquisition, zoning,
permit procurement and project management. In May 1997, CCIC acquired all the
outstanding shares of TEA. In June 1997, the Company purchased a minority
interest in VISI, which intends to provide computerized geographic information
for a variety of business applications (including site acquisition and
telecommunication network design).

In February 1997, CCIC, along with Candover Investments plc, TdF and
Berkshire, formed CTI to purchase the BBC Home Service Transmission Business.
Following the CTI Investment, the Company owned 34.3% of CTI. The BBC Home
Service Transmission Business included ownership of approximately 730 towers
in the United Kingdom and rights to locate broadcast transmission equipment on
an additional 558 towers in the United Kingdom owned by NTL, CTI's primary
competitor. In addition, CTI entered into a 10-year contract with the

64
<PAGE>

BBC to provide analog television and analog and digital radio transmission
services in the United Kingdom. With the acquisition of the BBC Transmission
Business, the Company, through its affiliation with CTI, gained access to an
expertise in broadcast transmission upon which the Company believes it can
capitalize in other markets.

In August 1997, CCIC expanded its tower footprints and enhanced its network
services offering in the United States by consummating the Crown Merger. The
assets acquired through the Crown Merger included 61 owned towers and
exclusive rights to lease antenna space on 147 other towers and rooftop sites,
most of which are located in and around the greater Pittsburgh area, giving
the Company a significant presence in that market. The remaining acquired
Crown communication sites are located in Pennsylvania, West Virginia,
Kentucky, Ohio and Delaware. The Crown assets included engineering and
operational expertise and management experience. The Crown Merger also
provided the Company with relationships with major wireless communications
carriers such as Aerial Communications, AirTouch Cellular, Bell Atlantic
Mobile, AT&T Wireless, PageNet, Nextel and Sprint PCS.

THE ROLL-UP

On April 24, 1998, the Company entered into a Share Exchange Agreement
pursuant to which, concurrently with the closing of the Offering, (i) all
shareholders of CTSH (other than the Company, TdF and DFI) will exchange their
shares of capital stock of CTSH for shares of Common Stock of the Company and
(ii) DFI will exchange its shares of capital stock of CTSH for shares of Class
A Common Stock of the Company. In connection with such exchanges, the Company
will exercise warrants to acquire additional shares of capital stock of CTSH
and subscribe for additional shares of capital stock of CTSH. Such
transactions are collectively referred to herein as the "Exchange". Upon
consummation of the Exchange, the Company will own 80.0% of CTSH and TdF will
own the remaining 20.0%. Immediately prior to the Exchange, (i) each share of
the Company's Existing Class A Common Stock will be converted into 1.523148
shares of Common Stock, (ii) each share of the Company's Existing Class B
Common Stock will be reclassified as one share of Common Stock and (iii) each
share of the Company's Existing Preferred Stock will be converted into one
share of Common Stock. See "The Roll-Up".

Upon the consummation of the Offering, after giving effect to the Roll-Up:
(i) DFI will own all of the outstanding Class A Common Stock (which is
convertible into shares of Common Stock and represents a 12.1% beneficial
ownership interest in the Company's Common Stock) and DFI and TdF together
will (after giving effect to the TdF Conversions) beneficially own 25.9% of
the Company's Common Stock; (ii) the Candover Group will beneficially own
12.1% of the Company's Common Stock; (iii) the Berkshire Group will
beneficially own 22.0% of the Company's Common Stock; (iv) the Centennial
Group will beneficially own 10.5% of the Company's Common Stock; (v) the Crown
Parties will beneficially own 7.0% of the Company's Common Stock; and (vi)
executive officers of the Company (excluding Mr. Crown) will beneficially own
7.4% of the Company's Common Stock. See "Principal and Selling Stockholders".

Following the Roll-Up, TdF will have certain significant governance and
other rights with respect to the Company and the CTI business. Subject to
certain conditions, TdF's consent will be required for the Company or CTI to
undertake certain actions, including making certain acquisitions or
dispositions, entering into strategic alliances with certain parties and
engaging in certain business combinations. See "Risk Factors--Risks Related to
Agreements with TdF" and "The Roll-Up--Roll-Up Agreements".

In addition, subject to certain conditions, (i) during the two year period
following consummation of the Offering, TdF will have the right to exchange
its shares of capital stock of CTSH for shares of Class A Common Stock of the
Company at the Exchange Ratio (as defined) and (ii) on the second anniversary
of the consummation of the Offering, the Company will have the right to
require TdF to exchange its shares of capital stock of CTSH for shares of
Class A Common Stock of the Company at the Exchange Ratio; provided, however,
that in each case TdF will retain ownership of one CTSH share and, therefore,
will retain its governance rights with respect to CTI until its ownership
interest in the Company falls below 5%. See "Risk Factors--Risks Related to
Agreements with TdF", "The Roll-Up--Roll-Up Agreements" and "Description of
Capital Stock".

BUSINESS STRATEGY

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

. LEVERAGE EXPERTISE OF CCI AND CTI PERSONNEL TO IMPLEMENT GLOBAL GROWTH
STRATEGY. The Company is seeking to leverage the skills of its personnel
in the United States and the United Kingdom. The Company believes that
its ability to manage networks, including the transmission of signals,
will be an important competitive advantage in its pursuit of global
growth opportunities. With its wireless communications and broadcast
transmission network design and radio frequency engineering expertise,
the Company is well positioned (i) to partner with major wireless
communications carriers to assume ownership of their existing towers,
(ii) to provide build-to-suit towers for wireless communications
carriers and broadcasters and (iii) to acquire existing broadcast
transmission networks that are being privatized around the world.

. PARTNER WITH WIRELESS COMMUNICATIONS CARRIERS TO ASSUME OWNERSHIP OF
THEIR EXISTING TOWERS. The Company is seeking to partner with major
wireless communications carriers to assume ownership of their existing
towers directly or through joint ventures. The Company believes 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 signals. Therefore, the Company
believes 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. The Company is
currently in discussions with major wireless communications carriers in
the United States to form joint ventures that would own and operate
their towers and believes that similar opportunities will arise globally
as the wireless communications industry further expands.

opportunities, leveraging on its ability to offer end-to-end services.
In addition, the Company intends to pursue build-to-suit opportunities
through any joint venture or similar arrangement it establishes in
connection with the acquisition of existing towers from wireless
communications carriers.

. ACQUIRE EXISTING BROADCAST TRANSMISSION NETWORKS. In 1997, CTI
successfully acquired the privatized domestic broadcast transmission
network of the BBC. In addition, the Company is implementing the roll-
out of digital television transmission services throughout the United
Kingdom. As a result of this experience, the Company is 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 acquiror
the ability to offer unused antenna capacity to new and existing radio
and television broadcasters and wireless communications carriers, as
well as to install new technologies such as digital terrestrial
transmission services. In addition, the Company's experience in
broadcast transmission services allows the Company to consider, when
attractive opportunities arise, acquiring wireless transmission networks
as well as the acquisition of associated wireless communications
infrastructure. The Company is currently pursuing a number of
international acquisition and privatization opportunities.

THE COMPANY

CCIC is a holding company that conducts all of its business through its
subsidiaries. CCIC's two principal operating subsidiaries are CCI, through
which it conducts its U.S. operations, and CTI, through which it conducts its
U.K. operations.

U.S. OPERATIONS

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

The Company leases antenna space to its customers on its owned and managed
towers. The Company generally receives fees for installing customers'
equipment and antennas on a tower and also receives monthly rental payments
from customers payable under site rental leases that generally range in length
from three to five years. The Company's U.S. customers include such companies
as Aerial Communications, AirTouch Cellular, Arch Communications, AT&T
Wireless, 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 Federal Bureau of Investigation,
the Internal Revenue Service and the U.S. Postal Service.

At June 30, 1998, the Company owned or managed 490 towers and 66 revenue
producing rooftop sites in the United States and Puerto Rico. In addition, the
Company had 1,217 rooftop sites under management throughout the United States
that were not revenue producing but were available for leasing to customers.
The Company's major U.S. tower footprints 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. The Company plans to enhance and expand
its tower footprints by building and acquiring multiple tenant towers in
locations attractive to site rental customers. To that end, the

67
<PAGE>

Company has developed, maintains and deploys for its own use extensive network
design and radio frequency engineering expertise, as well as site selection,
site acquisition and tower construction capabilities. The Company plans to
leverage CCI's expertise and experience in building and acquiring new towers
by entering into build-out, purchase or management contracts with various
carriers and tower owners. For example, pursuant to an agreement with Nextel,
as of June 30, 1998, the Company had constructed or purchased 42 sites, was in
the process of constructing or receiving permits for an additional 28 sites
and has the option to construct or purchase up to 108 additional multiple
tenant towers with Nextel as an anchor tenant along certain interstate
corridors. In addition, pursuant to this agreement, the Company purchased 46
of Nextel's existing towers clustered in various markets, including
Philadelphia, Houston, Dallas and San Antonio and has the option to purchase
four additional towers.

Communication Site Footprints

At June 30, 1998, the Company owned 361 towers and managed an additional 129
towers and 66 revenue producing rooftop sites in the United States and Puerto
Rico. The Company is in the process of building 47 towers. The following table
indicates, as of June 30, 1998, the type and geographic concentration of CCI's
owned and managed towers and revenue producing rooftop sites:

(a) CCI manages an additional 1,217 rooftop sites throughout the United States
that do not currently produce revenue but are available for leasing to its
customers.

The Company expects to significantly broaden its existing U.S. tower
footprints and expand into new strategically clustered sites by building
additional towers. To that end, the Company, through CCI, has developed and
maintains and deploys for its own use extensive network design and radio
frequency engineering expertise and tower construction capabilities. The
Company plans to leverage CCI's network design expertise 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.
Building a tower only after securing an anchor tenant, the Company usually has
been able to add additional carriers that have the same "dead zone", the
Company also plans to leverage CCI's expertise and experience in building new
towers by entering into build-out or purchase contracts with various carriers,
such as the Nextel Agreement. As of June 30, 1998, the Company had constructed
42 towers in western Pennsylvania, Ohio, Texas, South Carolina, Virginia and
North Carolina to enhance its regional presence in these areas. As part of the
Nextel Agreement, the Company had the option to build or purchase up to 250
towers along interstate highways in the midwestern and eastern United States
over the next two years. As of June 30, 1998, 42 of these sites had been
completed, an additional 28 sites were in various stages of permitting and
construction, ten sites had been identified as candidates for purchase and 62
sites had been rejected because they did not meet the Company's investment
criteria. See "--Significant Contracts--Nextel Agreement".

68
<PAGE>

The Company plans to use the towers acquired in the Crown Merger as a model
for the towers it intends to build when population density and perceived
demand are such that the Company believes the economics of constructing such
towers are justified. Management believes the Crown towers are superior to
those of its competitors because of their capacity and quality engineering.
The multiple tenant design of the Crown 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. Using only
hot dipped galvanized structures exceeding the standards of the American
National Standards Institute, Electronics Industry Association and
Telecommunications Industry Association, the Company builds towers capable of
accommodating a large number of wireless antennas. 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. Tower sites are designed to withstand severe wind, lightning and
icing conditions, have shelters with exclusive security card access and are
surrounded by ten foot barbed wire fences.

The Company also plans to acquire towers in order to develop new tower
footprints or to broaden its existing tower footprints. The Company believes
that wireless communications carriers have begun to seek to sell, or establish
joint ventures for the ownership of, their tower networks. See "Industry
Background". The Company is actively seeking to enter into such arrangements
with major wireless communications carriers. On a smaller scale, as part of
the Nextel Agreement, the Company has purchased 46 of Nextel's existing towers
and has the option to purchase an additional four towers. The Company believes
that these towers will provide it with a portfolio of strategic clusters in
Philadelphia, Houston, Dallas and San Antonio. The Company plans to continue
to acquire additional towers from carriers, such as Nextel, and other
independent tower operators as opportunities present themselves, although the
Company currently has no agreements with regard to any such acquisitions.

The Company generally believes it has significant capacity on a number of
its towers in the United States and Puerto Rico. Many of the towers it
acquired prior to the Crown Merger, however, may require significant
modifications and improvements to raise them to the quality specifications of
the Crown towers or to add additional customers. The Company intends to pursue
these upgrades where it believes it can achieve appropriate returns to merit
the necessary expenditure.

Products and Services

The Company's products and services can be broadly categorized as either
site rental, network services or broadcast site rental and services. Network
services provided through CCI include network design and site selection, site
acquisition, site development and construction and antenna installation.

Site Rental

In the United States, the Company rents antenna space on its owned and
managed towers and rooftops to a variety of carriers operating cellular, PCS,
SMR, ESMR, paging and other networks. The Company's U.S. site rental business
has its headquarters in Pittsburgh, with sales offices in Houston,
Albuquerque, Philadelphia and San Juan.

Tower Site Rental. The Company leases space to its customers on its owned
and managed towers. The Company generally receives fees for installing
customers' equipment and antennas on a tower (as provided in the Company's
network services programs) and also receives monthly rental payments from
customers payable under site leases. In the United States, the majority of the
Company's outstanding customer leases, and the new leases typically entered
into by the Company, 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.

69
<PAGE>

The Company also provides a range of site maintenance services in order to
support and enhance its site rental business. The Company believes that by
offering services such as antenna, base station and tower maintenance and
security monitoring, it is able to offer quality services to retain its
existing customers and attract future customers to its communication sites.
The Company was the first site management company in the United States
selected by a major wireless communications company to exclusively manage its
tower network and market the network to other carriers for co-location.

The following table describes the Company's top ten revenue producing towers
in the United States and Puerto Rico:

The Company has entered into master lease agreements with Aerial
Communications, AT&T Wireless, Bell Atlantic Mobile, 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. The Company has
also entered into an independent contractor agreement with Nextel. The Bell
Atlantic Mobile agreement has a 25-year master lease term through December
2020. The Company has also entered into a master lease agreement with Bell
Atlantic whereby the Company has the right to lease antenna space to customers
on towers controlled by Bell Atlantic Mobile. See "--Significant Contracts".

The Company has significant site rental opportunities arising out of its
agreements with Bell Atlantic Mobile and Nextel. In its lease agreement with
Bell Atlantic Mobile, the Company has exclusive leasing rights for 117
existing towers and currently has sublessees on 59 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 Bell Atlantic Mobile. To date Bell Atlantic Mobile has never failed
to approve a sublease proposed by CCI. In connection with the Nextel
Agreement, as of June 30, 1998, the Company has the option to own and operate
up to 108 additional towers. See "--Significant Contracts".

Rooftop Site Rental. The Company is a leading rooftop site management
company in the United States. Through its subsidiary, Spectrum, the Company
develops new sources of revenue for building owners by effectively managing
all aspects of rooftop telecommunications, including two-way radio systems,
microwave facilities, fiber optics, wireless cable, paging and rooftop
infrastructure services. Spectrum's staff includes radio frequency engineers,
managers, technicians and licensing personnel with extensive experience.

70
<PAGE>

The Company generally enters into management agreements with building owners
and receives a percentage of the revenues generated from the tenant license
agreements. Specifically, the Company designs and contracts these sites,
actively seeks multiple wireless communications carriers, prepares end-user
license agreements, and then manages and enforces the agreements. In addition,
the Company handles billing and collections and all calls and questions
regarding the site, totally relieving the building's management of this
responsibility.

Through Spectrum, the Company focuses on providing electronic compatibility
for antennas, and maximization of revenue for building owners. In the United
States, radio frequencies are assigned by the FCC but are not coordinated by
proposed site. For this reason, Spectrum has developed its own computerized
engineering program to determine the electronic compatibility of all users at
each site. This program enables Spectrum to maximize site usage. Spectrum
surveys each site and evaluates its location, height, physical and electronic
characteristics, and its engineers prepare a computer analysis to determine
the optimum location for different types of equipment and frequencies. Based
on this analysis, potential site users are identified.

In addition to the technical aspects of site management, the Company
provides operational support for both wireless communications carriers looking
to build out their wireless networks, and building owners seeking to outsource
their site rental activities. CCI stores and regularly updates relevant site
data, such as the location of communications and broadcast equipment, into a
database, which can be utilized to help wireless communications carriers plan
and build out their networks.

Network Services

Through designing, building and operating its own communication sites, the
Company, through CCI, has developed an in-house expertise in certain value-
added services that it offers to the wireless communications and broadcasting
industries. Because the Company views CCI as a turnkey provider with "end-to-
end" design, construction and operating expertise, it offers its 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. The Company has extensive experience in
network design and engineering and site selection. While the Company maintains
sophisticated network design services primarily to support the location and
construction of Company-owned multiple tenant towers, the Company does from
time to time provide network design and site selection services to carriers
and other customers on a consulting contract basis. The Company's network
design and site selection services provide 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 1997, the Company provided network design
services primarily for its own footprints and also for certain customers,
including Triton Communications, Nextel, Aerial Communications and Sprint.
These customers were typically charged on a time and materials basis.

To capitalize on the growing concerns over tower proliferation, the Company
has developed a program called "Network Solutions" through which it will
attempt to form strategic alliances with local governments to create a single
communications network in their communities. To date the Company's efforts
have focused on western Pennsylvania, where it has formed alliances with three
municipalities. These alliances are intended to accommodate wireless
communications 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 communications carriers and wireless customers.

Site Acquisition. In the United States, the Company is engaged in site
acquisition services for its 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

71
<PAGE>

possible land purchase or lease deals within the search ring. Within each
search 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, the Company's
construction department takes over the process of constructing the site.

The Company provides solutions to the NIMBY dilemma of wireless companies by
building more environmentally neutral and aesthetically acceptable towers.
Designs have included a clock tower, bell tower and others that will allow
communications companies to build in areas that otherwise would not permit a
tower to be built.

In 1997, CCI provided site acquisition services to eight customers,
including Aerial Communications, AirTouch Cellular, AT&T Wireless, Bell
Atlantic Mobile, BellSouth Mobility, GTE Mobilnet, Nextel, Omnipoint,
Pagemart, Sprint PCS and Teligent. These customers engage the Company for such
site acquisition services on either a fixed price contract or a time and
materials basis.

Site Development and Construction and Antenna Installation. The Company has
provided site development and construction and antenna installation services
to the U.S. communications industry for over 14 years. The Company has
extensive experience in the development and construction of tower sites and
the installation of antenna, microwave dishes and electrical and
telecommunications lines. The Company's site development and construction
services include clearing sites, laying foundations and electrical and
telecommunications lines, and constructing equipment shelters and towers. The
Company has designed and built and presently maintains tower sites for a
number of its wireless communications customers and a substantial part of its
own tower network. The Company can provide cost-effective and timely
completion of construction projects in part because its 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 the Company at its 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. The Company
generally sets 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 the Company may negotiate fees on individual sites or
for groups of sites. The Company has the capability and expertise to install
antenna systems for its paging, cellular, PCS, SMR, ESMR, microwave and
broadcasting customers. As this service is performed, the Company uses its
technical expertise to ensure that there is no interference with other
tenants. The Company typically bills for its antenna installation services on
a fixed price basis.

The Company's 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 1997, the Company provided site development and construction and antenna
services to approximately 21 customers in the United States, including Nextel,
Sprint PCS, AT&T Wireless, Aerial Communications and Bell Atlantic Mobile.

Broadcast Site Rental and Services

The Company also provides 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,
management believes 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".

72
<PAGE>

The Company is in the process of forming a joint venture with TdF to pursue
tall tower buildout and network ownership opportunities. This entity, which is
expected to be approximately 70%-owned by the Company, will seek to capitalize
on CTI's and TdF's experience in the broadcast transmission market.
Management's objective is to become a leader in the buildout of the
approximately 200 tall towers expected to be built in the United States over
the next five years. Management believes that the Company's experience in
providing digital transmission services in the United Kingdom will make the
joint venture an attractive provider of broadcast services to the major
networks and their affiliates. In addition, the joint venture will seek to
partner with public broadcasting stations that own property zoned for tall
towers, but that lack sufficient resources and expertise to build a tower.
After reaching agreement with the public broadcasting station, the joint
venture will attempt to co-locate on the tower the transmitters of major and
medium-sized commercial broadcast television stations and high powered FM
radio stations as well as wireless communications 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. The Company has developed an
ENG repeater system that can be used on many of its towers in western
Pennsylvania and expects to develop similar systems in other markets in which
it has or develops tower footprints. This system allows the ENG van to send a
signal to one of the Company's local towers where the signal is retransmitted
back to the television transmitter site. The retransmission of the signal from
the Company's tower to the various television transmitter sites is done via a
microwave link. The Company charges the station for the ENG receiver system at
the top of its tower and also charges them for the microwave dish they place
on its tower. The Company's ENG customers are affiliates of the NBC, ABC, CBS
and Fox networks.

The Company also has 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. The Company has installed master
FM and television systems on buildings across the country. It has supervised
the construction and operation of the largest master FM antenna facility in
the United States and has engineered and installed two 2,000 foot broadcast
towers with master FM antennas. Management believes that this experience may
help the Company negotiate favorable antenna site lease rates and 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

The Company has many agreements with telecommunications providers in the
United States, including leases, site management contracts and independent
contractor agreements. The Company's reciprocal leasing arrangements with Bell
Atlantic Mobile, its agreement with Nextel and the BellSouth Site Marketing
Agreement present unique opportunities for CCI to (i) acquire clusters of
towers in new markets, (ii) expand its existing tower footprints by
constructing multiple tenant towers with long-term anchor tenants and (iii)
increase utilization of existing towers and rooftop sites.

Bell Atlantic Mobile

On December 29, 1995, the Company and Bell Atlantic Mobile entered into two
separate 25-year master lease agreements relating to their towers in the
Pittsburgh MTA, one establishing certain terms and conditions of Bell Atlantic
Mobile's tenancy on the Company's towers and the other establishing certain
terms and conditions of the Company's sale of tenancy to other parties on
towers controlled by Bell Atlantic Mobile. In addition to providing site
rental revenue to the Company, the master leases allow each of the Company and
Bell Atlantic Mobile to sublease space on each other's towers in return for a
percentage of the rental revenue generated thereby.

73
<PAGE>

Bell Atlantic Mobile's master lease of space on the Company's towers
provides that Bell Atlantic Mobile's monthly site rental payments per tower
depend on the size of the equipment installed on the tower, the size of the
equipment building and the number of antennas. Rents are adjusted periodically
based on the Consumer Price Index. The Company performs all work at Bell
Atlantic Mobile's sites for tenants, including antennae installation,
grounding and foundations. Both of these master lease agreements included
rights of first refusal relating to certain spaces on towers leased by one of
the parties for which the other party had received a bona fide offer to buy.
In connection with the Crown Merger, the parties amended these master lease
agreements to eliminate the rights of first refusal, and Bell Atlantic waived
any such rights under these agreements that otherwise would have arisen in
connection with the Crown Merger.

The Company also leases space on all of Bell Atlantic Mobile's towers in the
Pittsburgh MTA (the "Bell Atlantic Agreement"). The terms and conditions of
the Company's master lease of space on towers controlled by Bell Atlantic
Mobile are substantially similar to Bell Atlantic Mobile's master lease with
the Company. The Company may sublease space on a tower controlled by Bell
Atlantic Mobile to another tenant, however, if the subtenant is to be AT&T,
the Company must receive the written consent of Bell Atlantic Mobile. To date,
the Company has 120 sublease contracts on Bell Atlantic Mobile-controlled
towers.

Nextel Agreement

On July 11, 1997, in connection with Nextel's proposed merger with PCI, the
Company and Nextel entered into the Nextel Agreement (the "Nextel Agreement"),
which establishes the framework under which the Company and Nextel will
conduct joint operations for the development of infrastructure within the
Nextel markets described below. Under the first part of this agreement, the
Company has purchased 46 existing towers from Nextel used in digital or analog
transmission in the greater metropolitan areas of Denver and Philadelphia and
in certain areas of the states of Texas and Florida, for a purchase price of
approximately $10.0 million.

In addition to the tower purchase, the Nextel Agreement provides that the
Company has the exclusive right and option to (i) develop, construct, own and
operate or (ii) purchase and operate, up to 250 new towers within selected
metropolitan areas, including Dallas and Houston, and parts of the interstate
highway corridors traversing the following states: Texas, Oklahoma, Louisiana,
Arkansas, Mississippi, Alabama, Georgia, South Carolina, North Carolina,
Tennessee, Kentucky, Virginia, Pennsylvania, New York, Ohio, Maryland and
New Jersey. This option extends from July 1997 until a minimum of 250
potential sites have been tendered to the Company. At June 30, 1998, Nextel
had tendered 142 sites to the Company, 80 of which met the Company's criteria
for investing in towers and, therefore, were accepted by the Company. Of these
80 sites, 28 sites are in the permitting process, ten sites have been
identified as candidates for purchase and 42 sites have been completed. Nextel
will perform all site acquisition work, including entering into agreements
with the fee owners of sites. If the Company waives its option to construct or
purchase new towers for an identified site tendered to it by Nextel, Nextel
may construct the tower itself or contract with a third party for the
construction. If the Company exercises its option to construct and own a
tower, it will reimburse Nextel for all costs of such site acquisition work.
If Nextel constructs a tower and the Company elects to purchase the
constructed tower, the Company will reimburse Nextel for all site acquisition
and construction costs associated with such towers. Following the completion
of construction of each tower, Nextel and the Company will, pursuant to
Nextel's master lease agreement, enter into a five-year lease contract with
four five-year renewal periods, at the option of Nextel. Nextel has a one-time
right of first refusal for a five-year period to lease additional space within
one designated 20-foot section of each tower.

If the Company elects to construct a new site, construction is to be
completed within a 60-day construction period that will not begin prior to
receipt of all regulatory permits and approvals (or a shorter period as
mutually agreed). In the event that the Company fails to complete any site
within the construction period, Nextel will be entitled to receive liquidated
damages for each such failure. If the Company fails to commence or complete
construction or to complete the installation of towers and related equipment
within the construction period, Nextel may exercise its option to purchase
such site at cost (after giving the Company an opportunity to cure). Nextel
may terminate the Nextel Agreement if the Company fails to complete
construction within the prescribed construction period or if Nextel exercises
its purchase option following certain construction delays by the

74
<PAGE>

Company for the greater of five towers or 5% of the aggregate number of total
sites committed to within a rolling eight-month period. In addition, the
Nextel Agreement provides that it may be terminated by Nextel upon the
insolvency or liquidation of CCI and it may be terminated by the Company upon
the insolvency or liquidation of Nextel. See "Risk Factors--Reliance on Nextel
Agreement".

BellSouth Site Marketing Agreement

On June 25, 1998, CCI and BellSouth Mobility entered into a Site Marketing
Agreement (the "BellSouth Site Marketing Agreement") pursuant to which CCI was
designated as the exclusive marketing agent for BellSouth's tower sites in the
State of Kentucky. CCI will facilitate the processing of site leases and
customer equipment installation at BellSouth sites. By mutual agreement, CCI
and BellSouth may extend the contract to cover other states. The contract has
an initial term of 100 days. After expiration of the initial term, unless
BellSouth and CCI shall have entered into an agreement to form a permanent
entity for the ownership, utilization and management of BellSouth's tower
sites, BellSouth may, at its election, either (i) extend the term of the
contract for five years or (ii) grant CCI the right to purchase BellSouth's
tower sites in Kentucky at their fair market value (but at not less than $75.0
million). If the contract is not extended or CCI elects not to purchase such
tower sites, the contract will expire pursuant to its terms.

Customers

In both its site rental and network services businesses, the Company works
with a number of customers in a variety of businesses including PCS, ESMR,
paging and broadcasting. The Company works with both large national carriers
such as Sprint PCS, Nextel, AT&T/Cellular One, Omnipoint and BellSouth
Mobility, and smaller local regional or private operators such as Aerial
Communications and Crescent Communications. For the six months ended June 30,
1998, the Company's largest U.S. customers were Sprint PCS and Nextel,
together representing 7.7% and 28.7%, respectively, of CCI's site rental
revenue and 14.1% and 32.1%, respectively, of CCI's network services revenues.
For the six months ended June 30, 1998, no customer accounted for more than
10.0% of CCI's revenues, other than Sprint PCS and Nextel, which accounted for
approximately 11.2% and 30.6%, respectively, of CCI's consolidated revenues.
Nextel revenues are expected to grow as CCI purchases Nextel towers and builds
out Nextel interstate corridor sites. The following is a list of CCI's top ten
site rental and network and other services customers, by percentage of
revenues for the six months ended June 30, 1998.

Sales and Marketing

CCI's sales and marketing personnel, located in Pittsburgh, Houston,
Albuquerque, Atlanta, Philadelphia, Albany, San Juan, Puerto Rico and Sao
Paulo, Brazil, target carriers expanding their networks, entering new markets,
bringing new technologies to market and requiring maintenance or add-on
business. All types of wireless service providers are targeted including
broadcast, cellular, paging, PCS, microwave and two-way radio. CCI is 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.
CCI's objective is to pre-sell capacity on CCI's towers by promoting sites
prior to construction. Rental space on existing towers is also aggressively
marketed and sold.

CCI utilizes 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 buildouts, 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 CCI's sales and
marketing personnel to target specific carriers' needs for specific sites. To
foster productive relationships with its major existing tenants and potential
tenants, CCI has 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 CCI's 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). CCI's promotional activities range from advertisements and site
listings in industry publications to maintaining a presence at national trade
shows. Potential clients are referred to CCI's Web site, which contains
Company information as well as site listings. In addition, CCI's 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 CCI via e-mail through the Web site or Cell Site
Express. CCI's network services capabilities are marketed in conjunction with
its tower footprints.

To follow up on targeted mailings and to cold-call on potential clients, CCI
has established a telemarketing department. Telemarketers field inbound and
outbound calls and forward leads to local 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, the Company competes with other independent tower
owners, some of which also provide site rental and network services; wireless
communications carriers, which own and operate their own tower networks;
service companies that provide engineering and site acquisition services; and
other potential

77
<PAGE>

competitors, such as utilities, outdoor advertisers and broadcasters, some of
which have already entered the tower industry. Wireless communications
carriers that own and operate their own tower networks generally are
substantially larger and have greater financial resources than the Company.
The Company believes 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. The Company also competes for acquisition and new tower
construction opportunities with wireless communications carriers, site
developers and other independent tower operating companies and believes 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 the Company.

The following is a list of certain of the tower companies that compete with
the Company in the United States: American Tower Corporation, Lodestar
Communications, Motorola, Specialty Teleconstructors, Pinnacle Tower, SBA
Communications, TeleCom Towers (an affiliate of Cox Communications), Unisite
and SpectraSite.

The following companies are primarily competitors for the Company's 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.

The Company believes that the majority of its 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). The Company offers its services
nationwide and the Company believes it is 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. The Company believes 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. The Company believes that it
competes favorably in these areas.

U.K. OPERATIONS

The Company, through its 80% interest in CTI, owns and operates one of the
world's most established television and radio transmission networks and is
expanding its leasing of antenna space on its towers to a variety of wireless
communications carriers. The Company provides transmission services for two
BBC 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 its 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 are Company-
owned (or leased or licensed to it by third parties) and the balance of which
are licensed to the Company under a site-sharing agreement (the "Site-Sharing
Agreement") with NTL, the Company's principal competitor in the United
Kingdom. The Company has also secured long-term contracts to provide digital
television transmission services to the BBC and BDB. See "--Significant
Contracts". In addition to providing transmission services, the Company also
leases antenna space on its transmission infrastructure to various
communications service providers and provides telecommunications network
installation and maintenance services and engineering consulting services.

The Company's 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

78
<PAGE>

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 June 30, 1998, approximately 61% of CTI's consolidated revenues
were derived from the provision of services to the BBC.

Communication Site Footprints

At June 30, 1998, the Company owned, leased or licensed 749 transmission
sites on which it operated 754 towers, was constructing eight new towers on
existing sites and had 38 site acquisition projects in process for new tower
sites. The Company has 54 revenue producing rooftop sites that are occupied by
the Company's transmitters but are not available for leasing to customers. The
Company's sites are located throughout England, Wales, Scotland and Northern
Ireland. The following table indicates, as of June 30, 1998, the type and
geographic concentration of the Company's U.K. towers and rooftop sites.

</TABLE>

The Company expects to significantly expand its existing tower footprints in
the United Kingdom by building and acquiring additional towers. The Company
believes its 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 its tower
footprints to wireless communications providers, the Company will seek to
build or acquire new communications towers. Using its team of over 300
engineers with state-of-the-art network design and radio frequency engineering
expertise, the Company locates sites and designs towers that will be
attractive to multiple tenants. The Company seeks 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,
Ionica, One2One, Orange and Scottish Telecom, thereby securing an anchor
tenant for a site before incurring capital expenditures for the site buildout.
As of June 30, 1998, the Company was building eight towers that it will own.
In addition, the Company expects to make strategic acquisitions of existing
communications sites (primarily those owned by wireless communications
operators) in order to expand its infrastructure and to further leverage its
site management experience.

The Company believes that it generally has significant capacity on its
towers in the United Kingdom. Although approximately 160 of its towers are
poles with limited capacity, the Company typically will be able to build new
towers that will support multiple tenants on these sites (subject to the
applicable planning process). The Company intends to upgrade these limited
capacity sites where it believes it can achieve appropriate returns to merit
the necessary capital expenditure. For example, in connection with a contract
with Vodafone, the Company is upgrading 68 of these sites with limited
capacity. See "--Significant Contracts--Vodafone". Approximately 59 of the
Company's 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.

Products and Services

Transmission Business

Analog. For the three months ended June 30, 1998, CTI generated
approximately 57% of its revenues from the provision of analog broadcast
transmission services to the BBC. Pursuant to the BBC Analog Transmission
Contract, the Company provides 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 June 30,
1998, the BBC Analog Transmission Contract generated revenues of approximately
(Pounds)46.6 million ($77.8 million) for the Company.

In addition to the BBC Analog Transmission Contract, the Company has
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.

The Company owns 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 June 30, 1998, CTI had
3,465 transmitters, of which 2,196 were for television broadcasting and 1,269
were for radio. These transmitters could be analyzed by transmission frequency
band as follows:

* Includes eleven transmitters owned by Virgin Radio and Talk Radio but
operated and maintained by CTI.

A few of the Company's most powerful 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 the Company's analog
television transmitters:

</TABLE>

All of the Company's 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 security
alarms connected to CTI's Technical Operations Centre at Warwick. The Site-
Sharing Agreement provides the Company with reciprocal access rights to NTL's
broadcast transmission sites on which the Company has equipment.

Certain of the Company's 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

80
<PAGE>

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. The Company has 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. The Company is committed to invest approximately
(Pounds)110.0 million ($183.6 million) for the buildout of new infrastructure
to support DTT over the next two years. 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 the Company with the remainder
owned by NTL. Currently, 24 sites are being upgraded. An arrangement similar
to that of the Site-Sharing Agreement is being negotiated to govern the
sharing of digital transmission sites between the Company and NTL.

CTI's capital costs are expected to be incurred in connection with the
acquisition and development of new transmission equipment.

The Company currently is 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 the Company's transmission network, and
this service is now broadcast to approximately 60% of the U.K. population. A
new independent national digital radio license is scheduled to be awarded in
1998. The Company's existing infrastructure and its experience with the BBC's
DAB network position it well to compete to provide transmission services to
the winner of this new radio license. In addition, local digital radio
licenses will be allocated in late 1998 or early 1999. The Company believes it
is similarly well situated 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. Currently, approximately 200
companies rent antenna space on approximately 405 of CTI's 808 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. The
Company's largest site rental customer in the United Kingdom is NTL under the
Site-Sharing Agreement. This agreement generated (Pounds)551,000 ($919,895) of
site rental revenue in June 1998.

The Company also provides a range of site maintenance services in order to
support and enhance its U.K. site rental business. The Company believes that
by offering services such as antenna, base station and tower maintenance and
monitoring, it is able to offer quality services to retain its existing
customers and attract future customers to its communications sites. The
Company complements its U.K. transmission experience with its site management
experience in the United States to provide customers with a top-of-the-line
package of service and technical support.

Other than NTL, CTI's largest (by revenue) site rental customers consist
mainly of wireless communications 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. 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.

The Company has master lease agreements with all of the major U.K.
telecommunications site users including BT, Cable & Wireless Communications,
Cellnet, Dolphin, Energis, Highway One, Ionica, 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 the Company's U.K. portfolio.
Customers make orders for specific sites using the standard terms included in
the master lease agreements. There are currently approximately 250
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. All the BBC Home Service Transmission
Business employees were retained by the Company upon CTI's acquisition.
Accordingly, the Company has engineering and technical staff of the caliber
and experience necessary not only to meet the requirements of its 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 three years, in Thailand, Taiwan, Poland
and Sri Lanka.

With the expertise of its engineers and technical staff, the Company is a
turn-key provider to the wireless communications and broadcast industries. The
Company 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.

82
<PAGE>

Site Acquisition. In the United Kingdom, the Company is involved in site
acquisition services for its own purposes and for third parties. The Company
recognizes that the site acquisition phase often carries the highest risk for
a project. To ensure the greatest possible likelihood of success and timely
acquisition, the Company combines 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. The Company
leverages off its experience in site acquisition and co-location when meeting
with local planning authorities.

Site Development and Antenna Installation. The Company uses a combination of
external and internal resources for site construction. The Company's 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 the Company has a long association, are used for
tower installation. Final antenna installation is undertaken by the Company's
own experienced teams.

Site Management and Other Services. The Company also provides complete site
management, preventive maintenance, fault repair and system management
services to the Scottish Ambulance Service. It also maintains a mobile radio
system for the Greater Manchester Police and provides 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 BDB
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. The Company 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. The Company has entered into contracts to design and
build communications equipment and related 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"). The BBC Analog
Transmission Contract provides for charges of approximately (Pounds)46.5
million ($77.6 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 ($500,850) 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 ($834,750) annually to the payments made by the BBC to the
Company.

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. The Company
believes 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 two 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

83
<PAGE>

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
the Company 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 the ability of CCIC and 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 both (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.

The BBC Commitment Agreement also required TdF Parent and the Company to
enter into services agreements with CTI. The services agreement entered into
by the Company and CTI is being terminated pursuant to the CTSH Shareholders'
Agreement. The services agreement entered into by TdF Parent and CTI (pursuant
to which TdF makes available certain technical consultants, executives and
engineers to CTI for a minimum term of three years commencing February 28,
1997) is being amended. Upon consummation of the Offering, the term of such
services agreement is expected to be extended for four additional years (to
February 28, 2004) and thereafter will be terminable on 12-month's prior
notice given by CTI to TdF after February 28, 2003. See "The Roll-Up--Roll-Up
Agreements--CTI Services Agreement".

BDB Digital Transmission Contract

In 1997, the Independent Television Commission awarded BDB three of the five
available commercial digital terrestrial television multiplexes for new
program services. The Company bid for and won the 12 year contract from BDB to
build and operate its digital television transmission network (the "BDB
Digital Transmission Contract"). The contract provides for approximately
(Pounds)20.0 million ($33.4 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.

BBC Digital Transmission Contract

In 1998, the Company 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 ($17.5 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 the Company's
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 the Company 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).

84
<PAGE>

BT Digital Distribution Contract

Under the BBC Digital Transmission Contract and the BDB Digital Transmission
Contract, in addition to providing digital terrestrial transmission services,
CTI has agreed to provide for the distribution of the BBC's and BDB's
broadcast signals from their respective television studios to CTI's
transmission network. Consequently, in May 1998, CTI entered into a
distribution contract (the "BT Digital Distribution Contract") with British
Telecommunications plc ("BT"), which will expire 12 years after the date on
which the Company commences digital terrestrial television transmission
services in the United Kingdom (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 the Company and NTL 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.

Vodafone

On April 16, 1998, under Vodafone's master lease agreement with the Company,
Vodafone agreed to locate antennas on 122 of the Company's existing
communication sites in the United Kingdom. The first 21 sites are expected to
be completed by the end of August 1998. Another 11 sites will require tower
strengthening and/or the acquisition of additional land and are expected to
take six to nine months to complete. Finally, 68 of the sites presently are
composed of a limited capacity tower and will therefore require the
construction of new towers, which will require full planning and zoning
approvals. These sites are expected to require six to 12 months to complete.
After their upgrade, these sites will be able to accommodate additional
tenants.

<PAGE>

Customers

For the six months ended June 30, 1998, the BBC accounted for approximately
59% of CTI's revenues. This percentage has decreased from 63% in 1997 and is
expected to continue to decline as CTI continues to expand its site rental
business and as DTT begins to be transmitted. 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, Scottish Telecom and
Ionica, with microwave links and backhaul infrastructure. The following is a

Sales and Marketing

The Company has 22 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.
The Company has begun to actively cross-sell its products and services so
that, for example, site rental customers are also offered build-to-suit
services. In addition, the Company recently hired a new Sales & Marketing
Director with 10 years of experience in the U.K. and U.S. wireless
telecommunications industries.

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 is expected to be awarded a similar
contract for the DTT service for SDN (CTI has been awarded similar contracts
for the BBC and BDB--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.

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, Simoco, 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

87
<PAGE>

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 June 30, 1998, the Company had approximately 487 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

The Company is 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, management
does not expect any pending matters to have a material adverse effect on the
Company's financial condition or results of operations.

EMPLOYEES

At June 30, 1998, the Company employed 836 people worldwide. Other than in
the United Kingdom, the Company is not a party to any collective bargaining
agreements. In the United Kingdom, the Company is 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. The Company has not experienced any strikes or work stoppages, and
management believes that the Company's employee relations are good.

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 has been registered with the FCC or a determination has been
made that such registration is not 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 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.

88
<PAGE>

The 1996 Telecom Act preempted 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) ban altogether the
construction, modification or placement of radio communications towers.
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. The Company, through certain
of its subsidiaries, holds licenses for radio transmission facilities granted
by the FCC, including licenses for common carrier microwave and paging
services and commercial mobile radio services ("CMRS"), which are subject to
additional regulation by the FCC. The Company is required to obtain the FCC's
approval prior to the transfer of control of any of its FCC licenses.
Consummation of the Offering and the Roll-Up may result in a transfer of
control of the Company under the FCC's rules and policies if, after such
transactions, over 50% of the voting stock of the Company would be owned by
new stockholders. As a precautionary measure, the Company has therefore
applied to the FCC for consent to transfer of control of the Company to the
post-Roll-Up and Offering stockholders to the extent such transactions would
require prior FCC approval. Because it is unlikely that the FCC will act on
these applications prior to the consummation of the Offering and the Roll-Up,
the Company requested special temporary authorizations from the FCC to
transfer control of its FCC licenses to the post-Roll-Up and Offering
stockholders, to the extent required under the FCC's rules and policies,
pending the FCC's action on the applications. The FCC has granted such special
temporary authorizations to the Company.

The Company, as the parent company of the licensees of common carrier and
CMRS facilities, is also subject to Section 310(b)(4) of the Communications
Act of 1934, as amended, which would limit the Company 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. Upon consummation of the Offering and the
Roll-Up, the Company will be 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. In
connection with the Offering, the Company petitioned the FCC for approval of
up to 49.9% foreign ownership, at least 25% of which will be from WTO-member
nations, and the FCC has ruled favorably upon the Company's request.

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.

89
<PAGE>

Licenses under the Telecommunications Act 1984

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

Transmission License. The Transmission License is a 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 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 an amendment to the Site-Sharing
Agreement and could in turn 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). 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).

90
<PAGE>

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 three 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:

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

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

(iii) two DAB Test and 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 is obligated under the BBC Analog Transmission Contract and the BBC
Digital Transmission Contract to pay most of those fees.

ENVIRONMENTAL MATTERS

The Company's 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, the Company is 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. The Company is potentially subject to cleanup
liabilities in both the United States and the United Kingdom.

The Company also is 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 the Company has not been subject to any
claims relating to RF emissions, it has established operating procedures
designed to reduce employee exposures to RF emissions and is presently
evaluating certain of its towers and transmission equipment in the United
States and the United Kingdom to determine whether RF emission reductions are
possible.

In addition, the Company is 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.

The Company believes that it is 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 the Company's business, results of
operations, or financial condition.

THE ROLL-UP

GENERAL

On April 24, 1998, the Company entered into a Share Exchange Agreement

shareholders of CTSH (other than the Company, TdF and DFI) will exchange their
shares of capital stock of CTSH for shares of Common Stock of the Company and
(ii) DFI will exchange its shares of capital stock of CTSH for shares of Class
A Common Stock of the Company. In connection with such exchanges, the Company
will exercise warrants to acquire additional shares of capital stock of CTSH
and subscribe for additional shares of capital stock of CTSH. Such
transactions are collectively referred to herein as the "Exchange". Upon
consummation of the Exchange, the Company will own 80.0% of CTSH and TdF will

(i) DFI will own all of the outstanding Class A Common Stock (which is
convertible into shares of Common Stock and represents a 12.1% beneficial
ownership interest in the Company's Common Stock) and DFI and TdF together
will beneficially own 25.9% of the Company's Common Stock (which gives effect
to TdF (i) exchanging its shares of, and warrants for, capital stock of CTSH
for shares of, and warrants for, Class A Common Stock, (ii) exercising such
warrants and (iii) converting such shares of Class A Common Stock into, and
DFI converting its shares of Class A Common Stock into, shares of Common Stock
(the "TdF Conversions")); (ii) the Candover Group will beneficially own 12.1%
of the Company's Common Stock; (iii) the Berkshire Group will beneficially own
22.0% of the Company's Common Stock; (iv) the Centennial Group will
beneficially own 10.5% of the Company's Common Stock; (v) the Crown Parties
will beneficially own 7.0% of the Company's Common Stock; and (vi) executive
officers of the Company (excluding Mr. Crown) will beneficially own 7.4% of
the Company's Common Stock. See "Principal and Selling Stockholders".

In addition, subject to certain conditions, (i) during the two-year period
following consummation of the Offering, TdF will have the right to exchange
its shares of capital stock of CTSH for shares of Class A Common Stock of the
Company at the Exchange Ratio and (ii) on the second anniversary of the
consummation of the Offering, the Company will have the right to require TdF
to exchange its shares of capital stock of CTSH for shares of Class A Common
Stock of the Company at the Exchange Ratio; provided, however, that in each
case TdF will retain its governance rights with respect to CTI until its
ownership interest in the Company falls below 5%. See "Risk Factors--Risks
Related to Agreements with TdF", "--Roll-Up Agreements" and "Description of
Capital Stock".

Share Exchange Agreement

On April 24, 1998, the Company entered into a Share Exchange Agreement (the
"Share Exchange Agreement") with CTSH, TdF, DFI and certain shareholders of
CTSH (the "CTSH Shareholders") in order to effect the exchange of certain CTSH
ordinary shares, nominal value 1 pence ("CTSH Ordinary Shares"), and CTSH
preference shares, nominal value 1 pence each ("CTSH Preference Shares" and,
together with the CTSH Ordinary Shares, the "CTSH Shares"), held by DFI and
the CTSH Shareholders for shares of Class A Common Stock of the Company, in
the case of DFI, and shares of Common Stock of the Company, in the case of the
CTSH Shareholders. DFI will exchange 1,620,000,000 CTSH Shares for 11,340,000
shares of Class A Common Stock of the Company and the remaining CTSH
Shareholders will exchange, in the aggregate, 2,981,100,000 CTSH Shares for
20,867,700 shares of Common Stock of the Company. The exchange ratio, in the
case of each CTSH Shareholder, was 7.0 shares of Common Stock and, in the case
of DFI, was 7.0 shares of Class A Common Stock, in each case for one CTSH
Ordinary Share together with 999 CTSH Preference Shares. In connection with
such exchanges, the Company will exercise warrants for 515,000,000 CTSH Shares
at 1 pence per share and subscribe for 10,210,000 CTSH Shares at 2.5 pence per
share. Following consummation of the Exchange, the Company and TdF will remain
as the only two shareholders of CTSH with the Company and TdF holding 80% and
20%, respectively, of the outstanding capital stock of CTSH.

Governance Agreement

Concurrently with the consummation of the Offering, the Company, TdF and DFI
will enter into the Governance Agreement (the "Governance Agreement") to
provide for certain rights and obligations of the Company, TdF and DFI with
respect to the governance of the Company following the consummation of the
Roll-up.

and/or any such subsidiary's pro rata Total Enterprise Value will be the
pro forma value of the entire interest);

(iv) any Strategic Alliance with certain parties;

(v) the disposition (other than with respect to asset swaps) in one or a

(including the assumption of any Indebtedness of the Company in connection
therewith) exceeds 10% of the Total Enterprise Value of the Company and its
subsidiaries taken as a whole; provided, however, that excluded from the
foregoing will be any disposition by the Company or any of its subsidiaries
of any specific interest of the Company and/or any of its subsidiaries in

the outstanding equity securities of the Company (it being understood that
any such issuance the consummation of which would result in a Business
Combination will be treated solely under the foregoing clause (vi)).

Governance Limitations. Subject to certain conditions, the super-majority
requirements described under "--Super-Majority Voting Requirements" above will
not apply if there is a vote of the Board under the following circumstances:
(i) following the second anniversary of the consummation of Roll-Up, six
independent directors have been elected to the Board and vote on the proposed
action; provided, however, that one existing independent director previously
has been replaced (other than the independent director initially nominated by
TdF) , (ii) seven independent directors have been elected to the Board and
vote on the proposed action; provided, however, that one existing independent
director previously has been replaced (other than the independent director
initially nominated by TdF) or (iii) any vote of the Board after the fifth
anniversary of the consummation of the Roll-Up.

Subject to certain conditions, following the fifth anniversary of the
consummation of the Roll-Up, the Company or any of its subsidiaries may take
any of the actions set forth in clauses (ii), (iii), (iv) and (v) under "--
Veto Rights" above without the prior written consent of TdF, and following the
tenth anniversary of the consummation of the Roll-Up, the Company or any of
its subsidiaries may take the action set forth in clauses (i), (vi) and (vii)
under "--Veto Rights" above without the prior written consent of TdF. Prior to
such fifth or tenth anniversary, as applicable, so long as TdF is Qualified,
no action by the Company or any subsidiary may be taken without the prior
written consent of TdF other than an action described in clauses (iii) and
(iv) under "--Veto Rights" above that, to TdF's knowledge (after having made
all reasonable inquiries in the circumstances of appropriate management of the
members of the TdF Group), is proposed to be entered into by any member of the
TdF Group in competition with, or to the exclusion of, the Company or any
subsidiary of the Company. In addition, no member of the TdF Group may enter
into any transaction falling within a Permitted Business Line that TdF vetoed
within six months after the relevant Veto.

95
<PAGE>

Anti-dilution

Except in certain circumstances described below, as long as TdF remains
Qualified, the Company will not issue, sell or transfer any equity securities
to any person (other than in connection with the Offering but only to the
extent that the consolidated percentage ownership interest of the TdF Group is
not thereby reduced to less than 20%) unless TdF is offered in writing the
right to purchase, at the same cash price and on the same other terms
proposed, an amount of such equity securities as is necessary for the TdF
Group to maintain its consolidated percentage ownership in the Company.

The anti-dilutive right set forth above does not apply in a number of
circumstances, including without limitation, the grant or exercise of certain
options to purchase Common Stock to employees, directors or consultants of the
Company and the issuance of shares of Common Stock issuable upon conversion
of, or in respect of dividends on, the Preferred Stock, or upon exercise of
the Senior Preferred Warrants.

Standstill

Subject to certain exceptions and the time limitations described under "--
Time Limitations" below, no member of the TdF Group will, without the prior
written consent of the Board: (a) acquire, offer to acquire, or agree to
acquire, by purchase, gift or otherwise, the beneficial ownership of any
voting securities of the Company if the ownership interest of the TdF Group
(the "TdF Group Interest") upon the consummation thereof would be greater than
the Relevant Percentage; (b) publicly propose that TdF or any member of the
TdF Group enter into, directly or indirectly, any Business Combination
involving the Company or propose to purchase, directly or indirectly, a
material portion of the assets of the Company or any subsidiary of the
Company, or make any such proposal privately (other than any such proposal
with respect to CTSH and its assets) if it would reasonably be expected to
require the Company to make a public announcement regarding such proposal; (c)
make, or in any way participate in, directly or indirectly, any "solicitation"
of "proxies" (as such terms are used in Regulation 14A promulgated under the
Exchange Act) to vote or consent with respect to any voting securities of the
Company in opposition to the recommendation of a Special Majority Vote of the
Board or become a "participant" in any "election contest" (as such terms are
defined or used in Rule 14a-11 under the Exchange Act) in opposition to the
recommendation of a Special Majority Vote of the Board; (d) act in concert
with any person for the purposes prohibited by subparagraph (a) or (b) above;
(e) except in accordance with the terms of the Stockholders Agreement, seek
election to or seek to place a representative on the Board or seek the removal
of any member of the Board; (f) (i) solicit, seek to effect, negotiate with or
provide nonpublic information to any other person with respect to or (ii)
otherwise make any public announcement or proposal whatsoever with respect to,
any form of business combination (with any person) involving a change of
control of the Company or the acquisition of a substantial portion of the
voting securities and/or equity securities or assets of the Company or any
subsidiary of the Company, including a merger, consolidation, tender offer,
exchange offer or liquidation of the Company assets, or any restructuring,
recapitalization or similar transaction with respect to the Company or any
subsidiary of the Company; or (g) publicly disclose any intention, plan or
arrangement, or provide advice or assistance to any person, inconsistent with
the foregoing.

Transfer Restrictions

Subject to certain time limitations described under "--Time Limitations"
below, TdF is subject to certain transfer restrictions on its voting
securities of the Company. Subject to certain limitations, such restrictions
do not apply to certain transactions, including without limitation, an
underwritten public offering, a sale pursuant to Rule 144(e) and Rule 144(f)
under the Securities Act and sales upon five business days' prior notice to
the Company pursuant to the terms of any tender or exchange offer for voting
securities of the Company made pursuant to the applicable provisions of the
Exchange Act or pursuant to any business combination. Subject to certain
limited exceptions, TdF or any member of the TdF Group desires to transfer to
any person 5% or more of the voting securities of the Company, the Company
will have the right to purchase all, or any part in excess of such 5%, of the
voting securities of the Company for cash at the price at which they are to be
transferred.

96
<PAGE>

Voting

Whenever TdF has the right to vote any voting securities of the Company and
any person has initiated, proposed or otherwise solicited stockholders of the
Company in a "proxy-contest" or any proposal for the election of any member to
the Board has received a negative vote, which in either case, has been
recommended by a Special Majority Vote of the Board, TdF will be present and
vote or consent with respect to all voting securities of the Company
beneficially owned by it in the manner recommended by a Special Majority Vote
of the Board or, if so requested by a Special Majority Vote of the Board, vote
or cause to be voted all voting securities of the Company beneficially owned
by it in the same proportion as the votes cast by or on behalf of the other
holders of voting securities of the Company.

Time Limitations

The standstill, transfer restriction and voting provisions described above
will cease to apply after the fifth anniversary of the consummation of the
Roll-Up or the earlier of: (i) any person (other than Berkshire Fund III, A
Limited Partnership, Berkshire Investors LLC and Berkshire Fund IV, Limited
Partnership, their affiliates and their respective partners or members (the
"Berkshire Group")) who holds, in person or as a group, less than the amount
permitted to be held by the Berkshire Group without such person constituting
an "Acquiring Person" under the Rights Plan beneficially owns or controls 15%
or more of the voting securities and/or 15% or more of the outstanding equity
securities (other than certain issuances of preferred stock) of the Company
without a standstill agreement (which includes customary standstill provisions
and terms no more favorable than those to which TdF is subject under the
Governance Agreement) being entered into between the Company and such person;
(ii) a business combination or other change in control of the Company has
occurred or has been agreed to or acquiesced in by the Board or the
consummation of (A) certain events described in the BBC Analog Transmission
Contract or the BBC Digital Transmission Contract, (B) any bona fide
unsolicited written offer by any person to acquire voting securities and/or
equity securities of the Company, which, if consummated, or any acquisition by
any person of any such securities which, when consummated, results in such
person beneficially owning, directly or indirectly, more than the Relevant
Percentage of the voting securities and/or equity securities of the Company
(an "Unsolicited Offer") or (C) a bona fide unsolicited written offer to
acquire a percentage of the equity securities of the Company which, if it were
to be consummated or otherwise allowed to occur without the consent or
approval of the BBC, would or might result in the BBC having the right to
terminate the BBC Analog Transmission Contract or the BBC Digital Transmission
Contract (a "Special Business Combination"); (iii) TdF is no longer Qualified;
(iv) no voting security of the Company is publicly traded; or (v) the Company
has redeemed the Rights under the Rights Plan.

In addition, the standstill and voting provisions described above will be
suspended during any period from the date of the commencement by any person
(other than TdF or any member of the TdF Group) of an Unsolicited Offer or a
Special Business Combination to the date of closing, abandonment or
termination of all such Offers (including any offer commenced by TdF or any
member of the TdF Group following such suspension) and will thereafter be
reinstated as in effect prior to the commencement of any such Unsolicited
Offer or Special Business Combination.

CTSH Option

TdF will have the right to exercise the CTSH Option (as defined below) if
TdF is Qualified and (i) the Board has approved a Business Combination by a
Special Majority Vote, TdF thereafter vetoes such Business Combination and,
subsequent to the exercise of the Veto by TdF, a majority of the entire Board
(excluding the two TdF Designees) resolves to override such Veto by TdF; (ii)
an Unsolicited Offer by any person (other than any member of the TdF Group)
has commenced or occurred; or (iii) a Special Business Combination has been
commenced by any person (other than any member of the TdF Group). The CTSH
Option is exercisable irrevocably by notice in writing given to the Company
within five days following agreement between the parties as to, or receipt of
notice of the determination of, the fair market value per share of the CTSH
Shares and certain warrants to purchase CTSH Shares (the "CTSH Warrants")
(assuming the payment of the exercise price of such

97
<PAGE>

Warrants) (the "CTSH Per Share Value"). Upon exercise, TdF will have the
option (the "CTSH Option") to (x) acquire for cash by itself or together with
any other person, all, but not less than all, the CTSH Shares beneficially
owned by the Company (the "Company CTSH Shares") at such CTSH Per Share Value,
(y) sell for cash to the Company the CTSH Shares beneficially owned by TdF
(the "TdF CTSH Shares") and the CTSH Warrants beneficially owned by TdF (the
"TdF CTSH Warrants") at such CTSH Per Share Value or (z) maintain the TdF CTSH
Shares and the TdF CTSH Warrants without regard to the event giving rise to
the CTSH Option.

In the case of an Unsolicited Offer or a Special Business Combination, if
TdF has elected to exercise the CTSH Option pursuant to clause (x) of the
first paragraph under "--CTSH Option" and the satisfaction or waiver of
certain specified conditions to such CTSH Option has not been obtained under
certain circumstances, TdF will have the option to declare the exercise of the
CTSH Option pursuant to such clause (x) to be null and void and to exercise
the CTSH Option pursuant to either clause (y) or clause (z) of the first
paragraph under "--CTSH Option" in lieu thereof.

If the Business Combination is not consummated (or an Unsolicited Offer or
Special Business Combination is abandoned or terminated) by reason primarily
of the exercise by TdF of the CTSH Option pursuant to clause (x) above, then
the Company may nevertheless require TdF to proceed with the purchase (the
"Required Purchase") of the Company CTSH Shares at the CTSH Per Share Value,
subject to the satisfaction or waiver of certain specified conditions and the
non-occurrence prior to the closing of the Required Purchase of (i) any event
or development of a state of circumstances or facts which has had or is
reasonably likely to have, individually or in the aggregate, a material
adverse effect on CTSH and its subsidiaries taken as a whole or (ii)(A) a
suspension of trading in the Company's Common Stock by the Commission or
Nasdaq or the establishment of limited or minimum prices in trading of
securities generally on the New York Stock Exchange, Inc., or Nasdaq or (B)
banking moratoriums having been declared either by Federal or New York State
authorities. If TdF exercises the CTSH Option pursuant to clause (x) in the
first paragraph of this section, TdF may pay all or any part of the purchase
price therefor by surrendering to the Company on the closing of such exercise
shares of Class A Common Stock (which will be valued at the offer price per
share of Common Stock pursuant to the Business Combination, Unsolicited Offer,
or Special Business Combination, as applicable, giving rise to the CTSH
Option).

Immediately prior to the consummation of any Business Combination,
Unsolicited Offer or Special Business Combination, TdF will have the right to
require the Company to purchase one-half of the shares of Class A Common Stock
held by the TdF Group, as applicable, for cash in an amount equal to the
product of (x) the offer price per share of Common Stock pursuant to the
Business Combination, Unsolicited Offer or Special Business Combination, as
applicable, and (y) one-half of the number of such shares of Class A Common
Stock held by the TdF Group.

unless (i) the closing of the TdF Put Right has previously been consummated,
(ii) the weighted average price per share of Common Stock over the five
trading days immediately preceding the second anniversary of the date of the

Company Call Right or the TdF Put Right, as the case may be, shall take place
on the tenth business day after the date on which TdF received the Company
Call Notice or the TdF Put Notice, as the case may be. Notwithstanding the
foregoing, if (A) (i) a legal prohibition prevents consummation of the Company
Call Right or the TdF Put Right, as the case may be, and TdF uses its
reasonable best efforts to remove any such legal prohibition, TdF will be
deemed to be Qualified for purposes of the Governance Agreement for the lesser

the Company Call Right or the TdF Put Right in respect of so many of the TdF
CTSH Shares and TdF CTSH Warrants as do not require the consent of the BBC,
and TdF shall be deemed to be Qualified for purposes of the Governance

efforts to obtain such removal or approval and (y) the TdF Consolidated Group
Interest is not less than 10.5%.

into the Stockholders Agreement (the "Stockholders Agreement") with certain
stockholders of the Company (the "Stockholders") to provide for the certain

and by all Stockholders exercising tag-along rights multiplied by (ii) the
number of securities to be offered.

CTSH Shareholders' Agreement

Concurrently with the consummation of the Offering, CCIC, TdF and CTSH will
enter 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 establishes that the
Board of CTSH will 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. Immediately following
consummation of the Offering, the Board will consist of Ted B. Miller, Jr.,
who will serve as Chairman of the Board, Charles C. Green III, Michel Azibert,
Michel Combes, George Reese and Alan Rees. CCIC has the right to nominate the
chairman, chief executive officer, chief operating officer and chief financial
officer of CTSH, subject to approval by a Special 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; issuances 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 (i) dividends payable in respect of CTSH's redeemable
preferred shares and (ii) 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 (a) entitle the BBC to
terminate either of the BBC contracts, (b) subject CTSH to possible revocation
of its licenses under the Telecommunications Act 1984 or the Wireless
Telegraphy Acts 1949, 1968 and 1998 or (c) 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 (a) the second
anniversary of the closing of the Roll-up, and (b) 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

104
<PAGE>

refusal is not exercised, the selling shareholder must procure an 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 (a) TdF has not exchanged its shares pursuant to the Governance
Agreement by the second anniversary of the closing of the Roll-Up, or (b)
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 (a) the second
anniversary of the closing of the Roll-Up, or (b) TdF ceasing to be Qualified
for purposes of the Governance Agreement, to require CCIC, upon at least six

any of the transfer provisions described above is subject to the fulfillment
of certain conditions precedent, including obtaining all necessary
governmental and regulatory consents.

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; 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, director or consultant. A change in
control generally accelerates the vesting of options granted to employees and
some of the options vest upon an initial public offering or 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 of Directors (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.

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 July 15, 1998, options to purchase a total of 12,450,615 shares of
Common Stock have been granted. Options for 363,125 shares of Common Stock
have been exercised, options for 162,500 shares have been forfeited and
options for 11,924,990 shares remain outstanding. The outstanding options are
for (i) 345,000 shares with an exercise price of $0.40 per share, (ii) 93,750
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) 1,680,625 shares with an exercise price of $4.20 per
share, (vi) 23,135 shares with an exercise price of $4.76 per share, (vii)
200,000 shares with an exercise price of $6.00 per share, (viii) 5,767,480
shares with an exercise price of $7.50 per share and (ix) 3,590,000 shares
with an exercise price equal to the price to public in the Offering. The
options exercisable at $0.40 per share are fully vested and held by Ted B.
Miller, Jr. Upon consummation of the Offering, vested and exercisable options
also include options for (i) 63,750 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)
1,483,625 shares at $4.20 per share, (v) 23,125 shares at $4.76 per share,
(vi) 200,000 shares at $6.00 per share, (vii) 2,704,480 shares at $7.50 per
share and (viii) 75,000 shares at the price to public in the Offering. 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) are included in the group of options vesting upon
consummation of the Offering. 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.

of Operations--Compensation Charges Related to Stock Option Grants".

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,
all of the outstanding options to purchase shares of capital stock of CTSH
("CTSH Options") granted pursuant to the CTSH Stock Option Plans will be
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 six months ended June 30, 1998
are noncash compensation charges for (Pounds)1.9 million ($3.2 million)
related to the issuance of stock options to certain executives and employees.

CTSH All Employee Share Option Scheme. All outstanding options granted
pursuant to the Castle Transmission Services (Holdings) Ltd. All Employee
Share Option Scheme (the "CTSH All Employee Plan") vest upon the consummation
of the Offering. Once vested, these options may only 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 sanctioning by the
U.K. courts of a compromise or arrangement pursuant to U.K. Companies Act 1985
section 425 that affects the Common Stock of the Company, (c) a person
becoming bound or entitled to acquire the Common Stock of the Company under
U.K. Companies Act 1985 sections 428-430 or (d) notice of a general meeting of

purpose of a voluntary winding-up of the Company (each of the foregoing, 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. There are currently outstanding options to purchase 285,250 shares
of Common Stock at a price of (Pounds)1.43 ($2.39) per share, of which an
initial refundable deposit of (Pounds)0.715 ($1.20) per share has already been
paid by each participant. No additional options will be granted under the CTSH
All Employee Plan in the future.

CTSH Management Plan. All outstanding options granted pursuant to the Castle
Transmission Services (Holdings) Ltd. Unapproved Share Option Scheme (the
"CTSH Management Plan") will vest on the earlier of (i) March 1, 2000 or, if

Management Plan) on March 1, 1997, the third anniversary of the date on which
the option was granted, (ii) the death of the option holder, (iii) the
termination of the option holder's employment with the Company (other than a

(iv) a Corporate Event or (v) the sale of the subsidiary or business of the

options granted pursuant to the CTSH Management 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

Currently, there are outstanding options to purchase 1,649,844 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 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 George E.

Stock at an exercise price of (Pounds)1.43 ($2.39) and 210,000 shares of the
Company's Common Stock at an exercise price of (Pounds)3.57 ($5.96). In
addition, the exercise prices of such options will be set in U.S. dollars,
converted from pounds sterling at the Noon Buying Rate on the date of the
consummation of the Offering.

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.

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

125
<PAGE>

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--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
Offering) 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. Upon completion of the Offering, there will be no shares of
Preferred Stock outstanding. See "Risk Factors--Anti-Takeover Provisions".

SENIOR PREFERRED WARRANTS

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,
provided that the price per share shall be reduced to 85% of the price per
share to the public if the Company consummates an initial registered public
offering of Common Stock with a price below $8.832 per share. The exercise
price is subject to weighted average antidilution protection. These warrants
are exercisable at any time prior to August 16, 2007, in the case of the
warrants issued in August 1997, and October 31, 2007, in the case of the
warrants issued in October 1997.

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

127
<PAGE>

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 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

128
<PAGE>

consummation of the Offering (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 that 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.

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

129
<PAGE>

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 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

130
<PAGE>

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 Offering.

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 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 June 30, 1998, the Borrowers had unused borrowing availability
under the Senior Credit Facility of approximately $27.5 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.

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

132
<PAGE>

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 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 June 30, 1998, CTI had unused borrowing
availability under the CTI Credit Facility of approximately (Pounds)35.0
million ($58.4 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 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

133
<PAGE>

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 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 "Notes"). The following is a summary of certain
terms of the Notes and is qualified in its entirety by reference to the
Indenture (the "Indenture") relating to the Notes. A copy of the Indenture has
been filed with the Registration Statement of which this Prospectus forms a
part.

The 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 Notes mature on November 15, 2007. The Notes
will accrete in value until November 15, 2002. Thereafter, cash interest will
accrue on the 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 notes are not redeemable prior to November 15,
2002. Thereafter, the 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
Notes at a redemption price equal to 110.625% of the accreted value of the
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 Notes remains outstanding after each such
redemption.

Upon the occurrence of a Change of Control (as defined in the Indenture),
each holder of Notes has the right to require the Company to purchase all or a
portion of such holder's 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 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 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.

134
<PAGE>

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.

SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of the Offering, the Company will have outstanding
82,548,545 shares of Common Stock (82,803,063 shares if the over-allotment
option is exercised in full). Of these shares, the 14,000,000 shares of Common
Stock (16,100,000 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 68,548,545 shares of Common Stock (66,703,063 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 or
Rule 701 under the Securities Act ("Rule 701"), is available. As a result of
the contractual restrictions described below and the provisions of Rule 144
and Rule 701, approximately 36,500,000 shares will be eligible for sale upon
expiration of the lock-up agreements 180 days after the date of this
Prospectus and approximately 32,000,000 shares will be eligible for sale upon
expiration of their respective one-year holding periods.

The Company has agreed, during the period beginning from the date of this
Prospectus and continuing to and including the date 180 days after the date of
this Prospectus, not to offer, sell, contract to sell or otherwise dispose of
any securities of the Company 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 Lehman Brothers Inc. In addition, the Company's directors and executive
officers and, with certain limited exceptions, all other existing stockholders
of the Company who represent in the aggregate approximately 83.0% of the
outstanding Common Stock after the Offering, will be required, during the
period beginning from the date of this Prospectus and continuing to and
including the date 180 days after the date of this Prospectus, not to,
directly or indirectly, offer, pledge, sell, contract to sell or otherwise
dispose of any securities of the Company 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 securities of the Company, without the prior written consent
of Lehman Brothers Inc. In addition to certain typical exceptions to such
"lock-up" agreements, each employee of the Company or its subsidiaries
(excluding Mr. Crown, certain executive officers and the directors of the
Company) that is a party to such an agreement is permitted to sell during the
180-day period described above up to 12% of the shares of Common Stock
beneficially owned or held under option by such employee as of the date of
this Prospectus; provided that such sales must be made in compliance with the
registration requirements of the Securities Act or pursuant to an exemption
therefrom; provided further that if any such employee has granted an option to
the U.S. Underwriters to sell additional shares to cover over-allotments, then
such employee's eligibility for this additional exception is reduced by the
number of shares sold upon exercise of the over-allotment option. 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 the Company 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 825,000 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 the Company or (if applicable)
the date they were acquired from an affiliate of the Company, a stockholder
who is not an affiliate of the Company at the time of sale and has not been an
affiliate of the Company 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.

136
<PAGE>

Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from the Company by its
employees, directors, officers, consultants or advisors prior to the date the
issuer becomes subject to the reporting requirements of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), pursuant to written
compensatory benefit plans or written contracts relating to the compensation
of such persons. In addition, the SEC has indicated that Rule 701 will apply
to typical stock options granted by an issuer before it becomes subject to the
reporting requirements of the Exchange Act, along with the shares acquired
upon exercise of such options (including exercises after the date of the
Offering). Securities issued in reliance on Rule 701 are restricted securities
and commencing 90 days after the Company becomes subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, subject to the
contractual restrictions described above, may be sold (i) by persons other
than affiliates, subject only to the manner of sale provisions of Rule 144,
and (ii) by affiliates, under Rule 144 without compliance with its one-year
minimum holding period requirements.

Following consummation of the Offering, the Company expects to file a
registration statement on Form S-8 covering approximately 22,500,000 shares of
Common Stock that are subject to outstanding options or reserved for issuance
under the Company's stock option plans.

Approximately 67,000,000 shares of Common Stock (approximately 99,000,000
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 180-day lockup
period described above, approximately 36,500,000 shares may be sold under Rule
144, subject to the volume restrictions contained therein.

Except as indicated above, the Company is unable to estimate the amount,
timing and nature of future sales of outstanding Common Stock. Prior to the
Offering, there has been no public market for the Common Stock, and 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--Shares Eligible for Future Sale" and
"Underwriting".

CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
TO NON-UNITED STATES HOLDERS

The following is a general summary of the material United States Federal
income and estate tax considerations to a Non-U.S. Holder (as defined below)
relevant to the ownership and disposition of shares of Common Stock. This
summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), final, temporary and proposed United States Treasury regulations
promulgated thereunder, Internal Revenue Service (the "IRS") rulings, official
pronouncements and judicial decisions, all as in effect on the date hereof and
all of which are subject to change, possibly with retroactive effect, or
different interpretations. This summary does not discuss all the tax
consequences that may be relevant to a particular Non-U.S. Holder in light of
the holder's particular circumstances and it is not intended to be applicable
in all respects to all categories of Non-U.S. Holders, some of whom may be
subject to special rules not discussed below. In addition, this summary does
not address any state, local or foreign tax considerations that may be
relevant to a Non-U.S. Holder's decision to purchase shares of Common Stock.

For purposes of this discussion, a "Non-U.S. Holder" is a person or entity
that, for U.S. Federal income tax purposes, is either a non-resident alien
individual, a foreign corporation, a foreign partnership or a foreign estate
or trust in each case not subject to U.S. Federal income tax on a net income
basis in respect of income or gain with respect to Common Stock. An individual
may be deemed to a resident alien (as opposed to a non-resident alien) by
virtue of being present in the United States on at least 31 days during the
calendar year and for an aggregate of 183 days during the calendar year and
the two preceding calendar years (counting, for such purposes all the days
present in the current year, one-third of the days present in the immediately
preceding year and one sixth of the days present in the second preceding
year). In addition to the "substantial presence test" described in the
immediately preceding sentence, an individual may be treated as a resident
alien if he or she (i) meets the lawful permanent residence test (a so-called
"green card" test) or (ii) elects to be treated as a U.S. resident and meets
the "substantial presence test" in the immediately following year. Generally,
resident aliens are subject to U.S. Federal income and estate tax in the same
manner as U.S. citizens and residents.

ALL NON-U.S. HOLDERS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING
THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE OWNERSHIP AND
DISPOSITION OF SHARES OF COMMON STOCK IN LIGHT OF THEIR OWN PARTICULAR
CIRCUMSTANCES.

DIVIDENDS ON COMMON STOCK

Generally, any dividends paid on Common Stock will be subject to United
States Federal withholding tax at a rate of 30% of the amount of the dividend,
or at a lower applicable treaty rate. However, if the dividend is effectively
connected with a United States trade or business of a Non-U.S. Holder (and is
attributable to a U.S. permanent establishment of such holder, if an
applicable income tax treaty so requires as a condition for the Non-U.S.
Holder to be subject to U.S. income tax on a net income basis in respect or
such dividends) it will be subject to United States Federal income tax on a
net basis at ordinary Federal income tax rates (in which case the branch
profits tax at 30% (or such lower rate as may be specified in an applicable
treaty) may also apply if such holder is a foreign corporation), and assuming
certain certification requirements are met, will not be subject to the 30%
withholding tax.

Under current Treasury regulations, a holder's status as a Non-U.S. Holder
and eligibility for a tax treaty reduced rate of withholding will be
determined by reference to the holder's address and to any outstanding
certificates or statements concerning eligibility for a reduced rate of
withholding, unless facts and circumstances indicate that reliance on such
address, certificates or statements is not warranted. However, subject to
certain transitional rules, recently issued Treasury regulations require a
Non-U.S. Holder to provide certifications under penalties of perjury in order
to obtain treaty benefits for payments made after December 31, 1999.

138
<PAGE>

SALE OR EXCHANGE OF COMMON STOCK

Subject to the discussion of backup withholding below, any capital gain
realized upon a sale or exchange of Common Stock by a beneficial owner who is
a Non-U.S. Holder ordinarily will not be subject to United States Federal
income tax unless (i) such gain is effectively connected with a trade or
business conducted by such Non-U.S. Holder within the United States (in which
case the branch profits tax at 30% (or such lower rate as may be specified in
an applicable treaty) may also apply if the holder is a foreign corporation),
(ii) in the case of a Non-U.S. Holder that is an individual, such holder is
present in the United States for a period or periods aggregating 183 days or
more in the taxable year of the sale or exchange and either (a) has a "tax
home" for Federal income tax purposes in the United States or (b) has an
office or other fixed place of business in the United States to which the gain
is attributable or (iii) the Company is or has been a "United States real
property holding corporation" (a "USRPHC") for Federal income tax purposes
within the lesser of (a) the five-year period ending on the date of the sale
or exchange and (b) the Non-U.S. Holder's holding period, and, in each case,
no treaty exception is applicable. The Company does not believe that it is
currently a USRPHC. Moreover, even if the Company were to become a USRPHC, any
gain recognized by a Non-U.S. Holder still would not be subject to U.S. tax if
the shares were to be "regularly traded" (within the meaning of applicable
Treasury regulations) on an established securities market (such as, for
example, the Nasdaq Stock Market) and the Non-U.S. Holder did not own,
directly or constructively, more than 5% of the outstanding Common Stock.

FEDERAL ESTATE TAXES

Common Stock that is beneficially owned by an individual who is neither a
citizen nor a resident of the United States at the time of death will be
included in such individual's gross estate for United States Federal estate
tax purposes, unless an applicable estate tax treaty provides otherwise.

BACKUP WITHHOLDING AND INFORMATION REPORTING

Generally, dividends on Common Stock paid to Non-U.S. Holders that are
subject to the 30% or a reduced treaty rate of United States Federal
withholding tax will be exempt from backup withholding tax. Otherwise, backup
withholding of United States Federal income tax at a rate of 31% may apply to
dividends paid with respect to Common Stock to holders that are not "exempt
recipients" and that fail to provide certain information (including the
holder's taxpayer identification number) in the manner required by United
States law and applicable regulations.

Payments of the proceeds from the sale by a Non-U.S. Holder of shares of
Common Stock made to or through a foreign office of a broker will not be
subject to information reporting or backup withholding except that if the
broker is a United States person, a controlled foreign corporation for United
States tax purposes or a foreign person 50% or more of whose gross income is
effectively connected with a United States trade or business for a specified
three-year period, information reporting may apply to such payments. Payments
of the proceeds from the sale of shares of Common Stock to or through the
United States office of a broker will be subject to information reporting and
backup withholding unless the holder certifies as to its non-United States
status or otherwise establishes an exemption from information reporting and
backup withholding. Subject to certain transitional rules, recently adopted
Treasury regulations change information reporting requirements for Non-U.S.
Holders for payments made after December 31, 1999. Accordingly, a Non-U.S.
Holder should consult its tax advisor regarding the effects on it, if any, of
these new regulations.

The U.S. Underwriting Agreement and the International Underwriting Agreement
(collectively, the "Underwriting Agreements" provide that the obligations of
the U.S. Underwriters and the International Managers to purchase shares of
Common Stock are subject to certain conditions, and that if any of the
foregoing shares of Common Stock are purchased by the U.S. Underwriters
pursuant to the U.S. Underwriting Agreement or by the International Managers
pursuant to the International Underwriting Agreement, then all the shares of
Common Stock agreed to be purchased by the U.S. Underwriters and the
International Managers, as the case may be, pursuant to their respective
Underwriting Agreement, must be so purchased. The offering price and
underwriting discounts and commissions per share for the U.S. Offering and the
International Offering are identical. The closing of the U.S. Offering is a
condition to the closing of the International Offering and the closing of the
International Offering is a condition to the closing of the U.S. Offering.

The Company, the Selling Stockholder and certain additional stockholders
identified below who may participate in the over-allotment option (as
described herein) have been advised by the Representatives that the U.S.
Underwriters and the International Managers propose to offer the shares of
Common Stock directly to the public at the public offering price set forth on
the cover page of this Prospectus, and to certain selected dealers (who may
include the U.S. Underwriters and the International Managers) at such public
offering price less a selling concession not in excess of $0.44 per share. The
selected dealers may reallow a concession not in excess of $0.10 per share to
certain brokers and dealers. After the Offering, the public offering price,
the concession to selected dealers and the reallowance may be changed by the
U.S. Underwriters and the International Managers.

The Company and the Selling Stockholder have agreed to indemnify, under
certain circumstances, the U.S. Underwriters and, in the case of the Company,
the International Managers against certain liabilities, including liabilities
under the Securities Act, and to contribute, under certain circumstances, to
payments that the U.S. Underwriters and, in the case of the Company, the
International Managers may be required to make in respect thereof.

The following Stockholders of the Company have granted to the U.S.
Underwriters options to purchase up to an aggregate of 2,100,000 additional
shares of Common Stock, exercisable solely to cover over-allotments, at the
public offering price less the underwriting discounts and commissions shown on
the cover page of this Prospectus: (i) Messrs. Miller, Ivy, Green, Gwyn, Rees
and Reese, each of whom is an executive of the Company or CTSH (the
"Executives"), have granted to the U.S. Underwriters options to purchase up to
an aggregate of 579,516 shares of Common Stock; (ii) Messrs. and Mmes.
Bettenhausen, Broussard, Cordell, Cunningham, Dennehy, Easter, Ellen,
Schueppert, Taylor, Turner, Uminski, Wallander, Ward and Wing, each of whom is
a member of management of the Company, CCI or CTSH (the "Employees"), have
granted to the U.S. Underwriters options to purchase up to an aggregate of
168,188 shares of Common Stock; and (iii) American Home Assurance Company,
Centennial Fund IV, L.P., Centennial Entrepreneurs Fund V, L.P., Centennial
Fund V, Fay, Richwhite Communications Limited, Harvard Private Capital
Holdings, Inc., Nassau Capital Partners II, L.P., NAS Partners I, L.L.C., New
York Life Insurance Company, The Northwestern Mutual Life Insurance Company,
PNC Venture Corp., Prime VIII, L.P., and Messrs. Neuger, Pinkerton and Smith,
each of which is an investor in the Company (the "Investors"), and Messrs.
Hutcheson, Martin and McKenzie each of whom is a director of the Company (the
"Directors" and together with the Investors, the "Sponsors"), have granted to
the U.S. Underwriters options to purchase up to an aggregate of 1,352,296
shares of Common Stock. Such options

141
<PAGE>

may be exercised at any time until 30 days after the date of the U.S.
Underwriting Agreement. To the extent that the over-allotment option is
exercised, each U.S. Underwriter or International Manager, as the case may be,
will be committed, subject to certain conditions, to purchase a number of
additional shares of Common Stock proportionate to such U.S. Underwriter's or
International Manager's initial commitment as indicated in the preceding
tables.

The Executives, the Employees and the Sponsors have agreed to indemnify,
under certain circumstances, the U.S. Underwriters against certain
liabilities, including liabilities under the Securities Act, and to
contribute, under certain circumstances, to the payments that the U.S.
Underwriters may be required to make in respect thereof.

Prior to the Offering, there has been no public market for the shares of
Common Stock. The initial public offering price was negotiated between the
Company and the Representatives. Among the factors considered in determining
the initial public offering price of the shares of Common Stock, in addition
to prevailing market conditions, were the Company's historical performance and
capital structure, estimates of business potential and earning prospects of
the Company, an overall assessment of the Company, an assessment of the
Company's management and the consideration of the above factors in relation to
market valuation of companies in related businesses.

The U.S. Underwriters and the International Managers have entered into an
Agreement Between U.S. Underwriters and International Managers pursuant to
which each U.S. Underwriter has agreed that, as part of the distribution of
the shares of Common Stock offered in the U.S. Offering, (i) it is not
purchasing any such shares for the account of anyone other than a U.S. or
Canadian Person (as defined below), and (ii) it has not offered or sold, will
not offer, sell, resell or deliver, directly or indirectly, any such shares or
distribute any prospectus relating to the U.S. Offering to anyone other than a
U.S. or Canadian Person. In addition, pursuant to such Agreement, each
International Manager has agreed that, as part of the distribution of the
shares of Common Stock offered in the International Offering, (i) it is not
purchasing any such shares for the account of a U.S. or Canadian Person, and
(ii) it has not offered or sold, and will not offer, sell, resell or deliver,
directly or indirectly, any of such shares or distribute any prospectus
relating to the International Offering to any U.S. or Canadian Person.

The foregoing limitations do not apply to stabilization transactions or to
certain other transactions specified in the Underwriting Agreements and the
Agreement Between U.S. Underwriters and International Managers, including (i)
certain purchases and sales between U.S. Underwriters and the International
Managers, (ii) certain offers, sales, resales, deliveries or distributions to
or through investment advisors or other persons exercising investment
discretion, (iii) purchases, offers or sales by a U.S. Underwriter who is also
acting as an International Manager or by an International Manager who is also
acting as a U.S. Underwriter and (iv) other transactions specifically approved
by the U.S. Representatives and the Lead Managers. As used herein, the term
"U.S. or Canadian Person" means any resident or citizen of the United States
or Canada, any corporation, partnership or other entity created or organized
in or under the laws of the United States or Canada or any political
subdivision thereof, or any estate or trust the income of which is subject to
United States or Canadian federal income taxation regardless of the source,
the term "United States" means the United States of America (including the
District of Columbia) and its territories, its possessions and other areas
subject to its jurisdiction, and the term "Canada" means Canada, its
provinces, its territories, its possessions and other areas subject to its
jurisdiction.

Pursuant to the Agreement Between the U.S. Underwriters and the
International Managers, sales may be made between the U.S. Underwriters and
the International Managers of such a number of shares of Common Stock as may
be mutually agreed. The price of any shares so sold shall be the public
offering price as then in effect for the shares of Common Stock being sold by
the U.S. Underwriters and the International Managers less an amount equal to
the selling concession allocable to such shares of Common Stock, unless
otherwise determined by mutual agreement. To the extent that there are sales
between the U.S. Underwriters and the International Managers pursuant to the
Agreement Between the U.S. Underwriters and the International Managers the
number of shares of Common Stock available for sale by the U.S. Underwriters
or by the International Managers may be more or less than the amount specified
on the cover page of this Prospectus.

142
<PAGE>

Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the U.S. Underwriters and certain selling
group members to bid for and purchase shares of Common Stock. As an exception
to these rules, the Representatives are permitted to engage in certain
transactions that stabilize the price of the Common Stock. Such transactions
may consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of the Common Stock.

If the U.S. Underwriters create a short position in the Common Stock in
connection with the Offering (i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus), the U.S.
Representatives may reduce that short position by purchasing Common Stock in
the open market. The U.S. Representatives also may elect to reduce any short
position by exercising all or part of the over-allotment option described
herein.

The U.S. Representatives may also impose a penalty bid on certain U.S.
Underwriters and selling group members. This means that, if the U.S.
Representatives purchase shares of Common Stock in the open market to reduce
the U.S. Underwriters' short position or to stabilize the price of the Common
Stock, they may reclaim the amount of the selling concession from the U.S.
Underwriters and selling group members who sold those shares as part of the
Offering.

In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
the Offering.

Neither the Company nor any of the U.S. Underwriters makes any
representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of the Common
Stock. In addition, neither the Company nor any of the U.S. Underwriters makes
any representation that the U.S. Representatives will engage in such
transactions or that such transactions, once commenced, will not be
discontinued without notice.

Each International Manager has represented and agreed that (i) it has not
offered or sold and, prior to the date six months after the date of issue of
the shares of Common Stock, will not offer or sell any shares of Common Stock
to persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995, (ii) it has complied and will comply with all
applicable provisions of the Financial Services Act 1986 with respect to
anything done by it in relation to the shares of Common Stock in, from or
otherwise involving the United Kingdom, and (iii) it has only issued or passed
on, and will only issue or pass on to any person in the United Kingdom any
document received by it in connection with the issue of the shares of Common
Stock if that person is of a kind described in Article 11(3) of the Financial
Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996.

The Common Stock has been approved for listing, subject to notice of
issuance, on The Nasdaq Stock Market's National Market under the symbol
"TWRS".

The Company, all executive officers and directors of the Company and,
subject to certain limited exceptions, all other existing stockholders of the
Company have agreed that they will not, subject to certain limited exceptions,
for a period of 180 days from the date of this Prospectus, directly or
indirectly, offer for sale, sell or otherwise dispose of any shares of Common
Stock or any securities convertible into or exchangeable or exercisable for
any such shares of Common Stock or enter into any derivative transaction with
similar effect as a sale of Common Stock, without the prior written consent of
Lehman Brothers Inc. The restrictions described in this paragraph do not apply
to (i) the sale of Common Stock to the Underwriters, (ii) the issuance by the
Company of shares of Common Stock upon the exercise of an option or a warrant
or the conversion of a security outstanding on the date of this Prospectus or
(iii) transfers, without consideration, of the Common Stock to family members
or to one or more trusts established for the benefit of one or more family
members. Furthermore, an

143
<PAGE>

additional exception was made for each employee of the Company or its
subsidiaries (excluding Mr. Crown, the Executives and the directors of the
Company) that is a party to a lock-up agreement to permit each such employee
to sell during the 180-day period described above up to 12% of the shares of
Common Stock beneficially owned by such employee as of the date of this
Prospectus; provided that such sales must be made in compliance with the
registration requirements of the Securities Act or pursuant to an exemption
therefrom; provided further that if any such employee is an Employee
participating in the over-allotment option described above, then such
Employee's eligibility for this additional exception is reduced by the number
of shares sold upon exercise of the over-allotment option.

Any offer of the shares of Common Stock in Canada will be made only pursuant
to an exemption from the prospectus filing requirement and an exemption from
the dealer registration requirement (where such an exemption is not available,
offers shall be made only by a registered dealer) in the relevant Canadian
jurisdiction where such offer is made.

Purchasers of the shares of Common Stock offered hereby may be required to
pay stamp taxes and other charges in accordance with the laws and practices of
the country of purchase, in addition to the offering price set forth on the
cover hereof.

The U.S. Underwriters and the International Managers have informed each of
the Company, the Selling Stockholders, the Executives, the Employees and the
Sponsors that they do not intend to sell to, and therefore will not confirm
the sales of shares of Common Stock to discretionary accounts to exceed five
percent of the total number of shares of Common Stock offered by them.

Lehman Brothers Inc. has provided investment banking, financial advisor and
other services to the Company, for which services Lehman Brothers Inc. has
received fees. In addition, Credit Suisse First Boston Corporation and its
affiliates has provided investment banking services to the Company and CTI,
for which it has received fees, and Credit Suisse First Boston, an affiliate
of Credit Suisse First Boston Corporation, has acted as arranger and agent of
the CTI Credit Facility in connection with which it has received fees. Salomon
Smith Barney, an affiliate of Smith Barney Inc., has acted as advisor to TdF
in connection with the negotiation of the Roll-Up, for which Salomon Smith
Barney received fees, and William A. Murphy, a Director of Mergers &
Acquisitions at Salomon Smith Barney, is expected to be elected as a director
of the Company upon consummation of the Roll-Up.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

The information contained in the following notes to the consolidated
financial statements is condensed from that which would appear in the annual
consolidated financial statements; accordingly, the consolidated financial
statements included herein should be reviewed in conjunction with the
consolidated financial statements for the fiscal year ended December 31, 1997,
and related notes thereto, of Crown Castle International Corp. included
elsewhere herein. All references to the "Company" include Crown Castle
International Corp. and its subsidiary companies unless otherwise indicated or
the context indicates otherwise.

The consolidated financial statements included herein are unaudited;
however, they include all adjustments (consisting only of normal recurring
adjustments) which, in the opinion of management, are necessary to present
fairly the consolidated financial position of the Company at June 30, 1998,
the consolidated results of operations for the three and six months ended June
30, 1997 and 1998 and consolidated cash flows for the six months ended June
30, 1997 and 1998. Accounting measurements at interim dates inherently involve
greater reliance on estimates than at year end. The results of operations for
the interim periods presented are not necessarily indicative of the results to
be expected for the entire year.

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. On a pro forma basis as if the TEA and Crown
acquisitions and the investment in Castle Transmission Services (Holdings) Ltd
("CTI") had been consummated as of January 1, 1997, the Company had
consolidated net revenues and a consolidated net loss for the six months ended
June 30, 1997 of $30,362,000 and $4,487,000 (a loss of $0.41 per common
share), respectively. Such pro forma results reflect appropriate adjustments
for depreciation and amortization, interest expense, amortization of deferred
financing costs, income taxes and certain nonrecurring income and expenses
recorded by the Company in connection with the investment in CTI. The pro
forma information does not necessarily reflect the actual results that would
have been achieved, not is it necessarily indicative of future consolidated
results for the Company.

4. 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>

The calculations of common shares outstanding for the diluted computations
exclude the following potential common shares as of June 30, 1998: (i) options
to purchase 5,280,510 shares of common stock at exercise prices ranging from
$.40 to $7.50 per share; (ii) warrants to purchase 1,314,990 shares of common
stock at an exercise price of $7.50 per share; (iii) shares of Senior
Convertible Preferred Stock which are convertible into 9,600,430 shares of
common stock; and (iv) shares of Series A Convertible Preferred Stock, Series
B Convertible Preferred Stock and Series C Convertible Preferred Stock which
are convertible into 28,888,665 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 all periods presented.

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.

6. SUBSEQUENT EVENTS

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
have agreed to exchange their shares of CTI for shares of the Company. Upon
the consummation of the exchange, the Company's ownership of CTI will increase
from approximately 34.3% to approximately 80%. Consummation of the share
exchange is subject to a number of significant conditions, including certain
third party consents and the consummation of an initial public offering of
common stock by the Company.

In connection with the share exchange, the Company intends to offer shares
of its common stock in an underwritten initial public offering during the
summer of 1998. On June 19, 1998, a registration statement in respect of such
initial public offering was filed with the Securities and Exchange Commission
(as amended, the "Registration Statement") and any securities offered in such
initial public offering will only be offered by means of a prospectus forming
a part of such Registration Statement.

In anticipation of such initial public offering, 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.

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 will vest upon consummation of the
initial public offering 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 an expected director nominee) 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 expected price to the public in the initial public offering, the Company
will record 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 initial public offering. Such compensation
charge will total approximately $18.4 million, of which approximately $10.6
million will be recognized upon consummation of the initial public offering
(for such options and shares which vest upon consummation of the initial
public offering), and the remaining $7.8 million will be recognized over five
years (approximately $1.6 million per year) through the second quarter of
2003.

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.

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, 1996 and 1997, and the
related consolidated statements of operations, cash flows and stockholders'
equity (deficit) for each of the three years in the period ended December 31,
1997. 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, 1996 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1997, 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 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 (a Delaware corporation) was organized on April 20, 1995. On
April 27, 1995, the stockholders of Castle Tower Corporation ("CTC")
contributed all of the outstanding shares of CTC's stock to the Company in
exchange for shares of the Company's stock. CTC (a Delaware corporation) was
organized on December 21, 1994 and began operations on January 1, 1995. The
Company and CTC have treated this exchange of securities as a reorganization
of entities under common control. As such, the transaction has been accounted
for as if it were a pooling of interests on January 1, 1995.

The Company owns, operates and manages wireless transmission towers and
rooftop sites, and also provides an array of related infrastructure and
network support services to the wireless communications and radio and
television broadcasting industries. The Company's primary business focus is
the leasing of antenna space on multiple tenant towers and rooftops to a
variety of wireless communications carriers under long-term lease contracts.
The Company's transmission towers and rooftop sites are located throughout the
United States and in Puerto Rico.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

an asset may not be recoverable. SFAS 121 was 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.

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 site selection and acquisition 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.

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

F-16
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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

A reconciliation of the numerators and denominators of the basic and diluted
per share computations is as follows:

<TABLE>
<CAPTION>

</TABLE>

The calculations of common shares outstanding for the diluted computations
exclude the following potential common shares as of December 31, 1997: (i)
options to purchase 3,694,375 shares of common stock at exercise prices
ranging from $.40 to $7.50 per share; (ii) warrants to purchase 1,314,990
shares of common stock at an exercise price of $7.50 per share; (iii) shares
of Senior Convertible Preferred Stock which are convertible into 9,050,060
shares of common stock; and (iv) shares of Series Preferred Stock (see Note 7)
which are convertible into 28,888,665 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, 1997.

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 is based on quoted market prices, and the estimated fair value of the
Convertible Secured Subordinated Notes is based on the most recent price at
which shares of the Company's stock were sold (see Note 5). 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:

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 plan (see Note 8). 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 8 for the disclosures required by SFAS 123.

Recent Accounting Pronouncements

In February 1997, the FASB issued Statement of Financial Accounting
Standards No. 128, Earnings per Share ("SFAS 128"). SFAS 128 establishes new
standards for computing and presenting earnings per share ("EPS") amounts for
companies with publicly held common stock or potential common stock. The new
standards require the presentation of both basic and diluted EPS amounts for
companies with complex capital structures. Basic EPS is computed by dividing
income available to common stockholders by the weighted-average number of
common shares outstanding for the period, and excludes the effect of
potentially dilutive securities (such as options, warrants and convertible
securities) which are convertible into common stock. Dilutive EPS reflects the
potential dilution from such convertible securities. SFAS 128 is effective for
periods ending after December 15, 1997. The Company has adopted the
requirements of SFAS 128 in its financial statements for the year ended
December 31, 1997.

In February 1997, the FASB issued Statement of Financial Accounting
Standards No. 129, Disclosure of Information about Capital Structure ("SFAS
129"). SFAS 129 establishes standards for disclosing information about a
company's outstanding debt and equity securities and eliminates exemptions
from such reporting requirements for nonpublic companies. SFAS 129 is
effective for periods ending after December 15, 1997. The Company has adopted
the requirements of SFAS 129 in its financial statements for the year ended
December 31, 1996.

F-18
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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 will adopt the requirements of
SFAS 131 in its financial statements for the year ending December 31, 1998.

2. ACQUISITIONS

During the three years in the period ended December 31, 1997, 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.

Pittencrieff Communications, Inc. ("PCI")

From January 9, 1995 through November 1, 1995, the Company acquired 127
telecommunications towers and related assets, net of certain outstanding
liabilities, from PCI. The total purchase price of $16,179,000 consisted of
$15,122,000 in cash, a note payable to PCI for $762,000 and the assumption of
a note payable to a third party for $295,000.

The Company entered into a license agreement with PCI under which PCI leases
space on certain of the towers for its telecommunications equipment. This
license agreement was assumed by Nextel Communications, Inc. ("Nextel") upon
its acquisition of PCI in 1997. The license agreement commenced on January 1,
1995 and expires on December 31, 2008, at which time Nextel has the option to
renew the license agreement for an additional three year term.

The Company also entered into a management agreement with PCI under which
PCI managed the towers for the Company. The term of this management agreement
was for one year commencing on January 1, 1995. The Company paid a management
fee to PCI equal to 15% of the revenues generated by the towers. Such
management fees amounted to $553,000 for the year ended December 31, 1995. The
Company began managing the towers on January 1, 1996.

Spectrum Engineering Company ("Spectrum")

On October 30, 1995, the Company acquired substantially all of the property
and equipment of Spectrum for $1,185,000 in cash. Spectrum provides management
services for building rooftop antenna sites. The Company recognized goodwill
of $870,000 in connection with this 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 1995 and 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 $1,476,000 consisted
of $1,211,000 in cash and a $265,000 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

F-19
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

$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 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 7), 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
CTC with and into CCI, establishing CCI as the principal operating subsidiary
of the Company.

Pro Forma Results of Operations (Unaudited)

The following unaudited pro forma summary presents consolidated results of
operations for the Company as if (i) the Motorola and other acquisitions had
been consummated on January 1, 1996 and (ii) the TEA and Crown acquisitions
and the investment in Castle Transmission Services (Holdings) Ltd ("CTI") had
been consummated as of January 1 for both 1996 and 1997. Appropriate
adjustments have been reflected for depreciation and amortization, interest
expense, amortization of deferred financing costs, income taxes and certain
nonrecurring income and expenses recorded by the Company in connection with
the investment in CTI (see Note 4). The pro forma information does not
necessarily reflect the actual results that would have been achieved, nor is
it necessarily indicative of future consolidated results for the Company.

4. INVESTMENTS IN AFFILIATES

Investment in Castle Transmission Services (Holdings) Ltd ("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 7) 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 accounts for its
investment in CTI utilizing the equity method of accounting.

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. At December
31, 1996, approximately $953,000 of such reimbursable costs are included in
other receivables on the Company's consolidated balance sheet.

The Company receives a monthly service fee from CTI of approximately $33,000
as compensation for certain management services. This fee is included in
network services and other revenues on the Company's consolidated statement of
operations.

CTI uses the British pound as the functional currency for its operations.
The Company translates its equity in the earnings and losses of CTI using the
average exchange rate for the period, and translates its investment in CTI
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.

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.

Summarized financial information for CTI is as follows:

Investment in Visual Intelligence Systems, Inc. ("VISI")

On June 23, 1997, the Company made an investment in VISI of $2,000,000 (of
which $100,000 was paid in 1996). VISI intends to provide computerized
geographic information for a variety of business applications, including the
acquisition and design of telecommunications sites. The Company's investment
was made in the form of 15,000 shares of VISI's common stock at a price of
$2.00 per share, along with a Convertible Subordinated Note for $1,970,000
(the "VISI Note"). The VISI Note is convertible (at the option of the Company)
into shares of VISI's common stock at a conversion price of $2.00 per share,
bears interest at 7.11% per year and is due on May 31, 2007. The 15,000 shares
of common stock purchased by the Company represent an ownership interest of
approximately 1.14% in VISI. The Company accounts for its investment in VISI's
common stock utilizing the cost method of accounting.

Bank Credit Agreement and Senior Credit Facility

On April 26, 1995, CTC entered into a credit agreement with a bank (as
amended, the "Bank Credit Agreement"). The Bank Credit Agreement 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 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 7), 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). 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).
As of December 31, 1997, approximately $93,600,000 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, 1997. Upon the merger of CTC into CCI in January 1998, CCI became the
primary borrower under the Senior Credit Facility.

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

F-23
<PAGE>

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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
the Company's subsidiaries and the Company's pledge of the capital stock of
its subsidiaries. In addition, the Senior Credit Facility is guaranteed by the
Company. As of December 31, 1997, 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% (10.0% and 8.98%, respectively, at December 31, 1997). 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, 1997, 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 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 the Promissory Note payable, including
accrued interest thereon, to PCI; 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 at December 31, 1997.

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 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, 1997, the Company was
precluded from paying dividends on its capital stock under the terms of the
Indenture.

Reporting Requirements Under the Indenture (Unaudited)

As of December 31, 1997, the Company does not have any Unrestricted
Subsidiaries (as defined in the Indenture). The following information (as such
capitalized terms are defined in the Indenture) is presented solely

F-24

for the purpose of measuring compliance with respect to the terms of the
Indenture; such information is not intended as an alternative measure of

Promissory Note Payable to PCI

This note bore interest at a rate of 8% per annum, called for equal annual
payments of principal and interest and was secured by the tower sites
purchased from PCI. The Company repaid this note with a portion of the
proceeds from the issuance of its 10 5/8% Senior Discount Notes (as discussed
above).

Convertible Secured Subordinated Notes Payable to Stockholder

These notes accrued interest at a rate of 8% per annum, payable at maturity,
and were secured by substantially all of CTC's assets. The notes provided that
the holder had the option, at any time, to convert such notes, in whole or in
part, into shares of the Company's Series A Convertible Preferred Stock at a
conversion price of $6.00 per share. On April 27, 1995, a portion of the notes
with aggregate principal balances of $743,000 was converted into 123,742
shares of the Company's stock and the related accrued interest was paid to the
holder. On February 24, 1997, the remaining $3,125,000 principal amount of the
notes was converted into 520,878 shares of the Company's stock and, by mutual
agreement with the holder, the related accrued interest was forfeited. Upon
conversion of the notes, the principal amount and the forfeited interest were
accounted for as increases to redeemable preferred stock and additional paid-
in capital, respectively.

Restricted Net Assets of Subsidiaries

Under the terms of the Senior Credit Facility, the Company's subsidiaries
are limited in the amount of dividends which can be paid to the Company. 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 subsidiaries. The restricted net
assets of the Company's subsidiaries totaled $232,229,000 at December 31,
1997.

Interest Rate Swap Agreement

The interest rate swap agreement has an outstanding notional amount of
$17,925,000 at January 29, 1997 (inception) and terminates on February 24,
1999. The Company pays a fixed rate of 6.28% on the notional amount and
receives a floating rate based on LIBOR. This agreement effectively changes
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.

At December 31, 1997, the Company has net operating loss carryforwards of
approximately $20,000,000 which are available to offset future federal taxable
income. These loss carryforwards will expire in 2010 through 2012. The
utilization of the loss carryforwards is subject to certain limitations.

7. REDEEMABLE 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 are entitled to receive cumulative
dividends at the rate of 12.5% per share, compounded annually. At December 31,
1997, such accrued and unpaid dividends amounted to $2,199,000. Any payment of
such dividends would be in the form of additional shares of Senior Preferred
Stock until such time as the Company is permitted to pay cash dividends on its
capital stock under the terms of the Indenture (see Note 5). At the option of
the holder, each share of Senior Preferred Stock (plus any accrued and unpaid
dividends) is convertible, at any time, into shares of the Company's Class B
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 represents the estimated fair value of the Class B Common
Stock on that date. The holders of the Senior Preferred Stock are entitled to
vote together with the holders of the Company's other preferred stock on an
as-converted basis.

The Company has the one-time right, within one year from the date of
issuance, to redeem 50% of the outstanding shares of Senior Preferred Stock at
a price per share which represents an annualized cumulative rate of return of
18%. If not earlier converted or redeemed, the shares of Senior Preferred
Stock are subject to mandatory redemption by the Company, at a price per share
of $100 plus any accrued and unpaid dividends through that date, upon the
earlier of (i) 91 days after the tenth anniversary date of the issuance of the
Notes; or (ii) May 15, 2008. The Senior Preferred Stock also calls for a
preference, in the event of a liquidation or a change in voting control, equal
to a price per share which represents an annualized cumulative rate of return
of 18%. With respect to dividend, redemption and liquidation preferences, the
rights of the holders of the Senior Preferred Stock are senior to the
Company's other preferred and common stock.

The purchasers of the Senior Preferred Stock were also issued warrants to
purchase an aggregate 1,314,990 shares of the Company's Class B 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 represents the estimated fair value of the Class B Common Stock
on that date. As such, the Company has not assigned any value to the warrants
in its consolidated financial statements.

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") are
generally entitled to one vote per share on all matters presented to a vote of
the Company's stockholders. The holders of the Series Preferred Stock are also
entitled to receive dividends, if and when declared, at the same rate as
dividends are declared and paid with respect to the Company's common stock. At
the option of the holder, each share of Series Preferred Stock is convertible,
at any time, into five shares of the Company's Class B Common Stock. Each of
the outstanding shares of Series Preferred Stock will automatically convert
into five shares of Class B Common Stock in the event of an underwritten
public offering of the Company's common stock, subject to certain conditions.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

Upon the earlier of (i) 91 days after the tenth anniversary date of the
issuance of the Notes; or (ii) May 15, 2008, the outstanding shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock are
redeemable, at the option of the holder, at a price per share of $6.00, $12.00
and $21.00, respectively, plus any accrued and unpaid dividends through the
date of redemption. The Series Preferred Stock also call for liquidation
preferences equal to such respective redemption prices. With respect to
redemption and liquidation preferences, the rights of the holders of the
Series C Preferred Stock and the Series B Preferred Stock are senior to the
Series A Preferred Stock and the common stock, and the rights of the holders
of the Series A Preferred Stock are senior to the common stock.

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).

8. STOCKHOLDERS' EQUITY (DEFICIT)

Common Stock

At the option of the holder, each share of the Company's Class A Common
Stock is convertible, at any time, into 1.52315 shares of the Company's Class
B Common Stock. The holders of the Class B Common Stock are entitled to one
vote per share on all matters presented to a vote of the Company's
stockholders, and the holders of the Class A Common Stock are entitled to a
number of votes equivalent to the number of shares of Class B Common Stock
into which their shares of Class A Common Stock are convertible. The holders
of the Class A Common Stock are also entitled to receive dividends, if and
when declared, on an equivalent basis with the holders of the Class B Common
Stock. In the event of an underwritten public offering of its common stock
which results in the conversion of the Preferred Stock (see Note 7), the
Company may, at its option, require that all outstanding shares of Class A
Common Stock be converted into Class B 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.

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 5,765,000 shares
of the Company's Class B Common Stock are 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. A
summary of awards granted under the 1995 Stock Option Plan is as follows for
the years ended December 31, 1995, 1996 and 1997:

The weighted-average fair value of options granted during the years ended
December 31, 1995, 1996 and 1997 was $0.09, $0.50 and $1.30, 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):

<TABLE>

Expected life.................................. 3.2 years 4.0 years 4.5 years
Expected volatility............................ 0% 0% 0%
Expected dividend yield........................ 0% 0% 0%
</TABLE>

The exercise prices for options granted during the years ended December 31,
1995, 1996 and 1997 were equal to or in excess of the estimated fair value of
the Company's Class B Common Stock at the date of grant. As such, no
compensation cost was recognized for stock options during those years (see
Note 1). 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, 1995, 1996 and 1997 would have been $33,000
($0.01 per share), $973,000 ($0.28 per share) and $12,586,000 ($2.37 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.

Shares Reserved For Issuance

9. 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 15% or 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 for the year ended
December 31, 1997.

10. 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 $22,000,
$50,000 and $130,000 for the years ended December 31, 1995, 1996 and 1997,
respectively.

Included in other receivables at December 31, 1997 are amounts due from
employees of the Company totaling $499,000.

11. COMMITMENTS AND CONTINGENCIES

At December 31, 1997, minimum rental commitments under operating leases are
as follows: years ending December 31, 1998--$2,634,000; 1999--$2,483,000;
2000--$2,021,000; 2001--$1,791,000; 2002--$1,131,000; thereafter--$17,228,000.
Rental expense for operating leases was $208,000, $277,000 and $1,712,000 for
the years ended December 31, 1995, 1996 and 1997, 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.

12. 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
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.

For the years ended December 31, 1995, 1996 and 1997, the Company's revenues
from PCI and Nextel amounted to $2,566,000, $2,634,000 and $5,998,000,
respectively.

subchapter S corporation, Airport Communications, Inc. (ACI), a subchapter S
corporation and E-90, Ltd. (E-90), a Pennsylvania Business Trust
(collectively, Crown Communications or the Company). These entities are all
under common ownership. All significant intercompany accounts and transactions
have been eliminated.

Crown Communications is a communication site development and management
company. The Company's core business is the development of high density
communication facilities. The majority of these facilities are located
throughout western Pennsylvania. The Company leases antenna and transmitter
space on communication towers to companies using or providing wireless
telephone, paging and specialized mobile radio services.

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.

(b) Cash and Cash Equivalents

The Company considers cash in depository institutions and short-term
investments with original maturities of three months or less to be cash and
cash equivalents.

Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method.

(d) Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation.
Depreciation on property and equipment is computed utilizing methods which
approximate the straight-line method over the estimated useful lives of the
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 is 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 combined financial statements.

(e) Other Assets

Other assets include deferred financing costs which are amortized over the
estimated term of the related borrowing.

(f) Revenue Recognition

Equipment sales revenues are recognized when products are delivered to
customers.

Site rental revenue is recognized ratably over the terms of the respective
leases. Such leases have terms that are generally five years.

Network services revenues are recognized under a method which approximates
the completed contract method. This method is used because typical network
services are completed in 3 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. The network services are considered
complete at the point in time in which the terms and conditions of the
contract and/or agreement have been substantially completed. Revenues from
completed contracts which have not been billed at the end of an accounting
period are presented as accrued network services.

Costs and revenues associated with installations not complete at the end of
an accounting period are deferred and recognized when the installation becomes
operational. Any losses on contracts are recognized at such time as they
become known.

(2) INCOME TAXES

CCM is operated as a sole proprietorship and all income or loss is passed
through to the personal tax return of the owners. The shareholders for CNS,
CMS and ACI have elected under subchapter S of the Internal Revenue Code to
pass through all income or loss to the individual tax return of the
shareholders. E-90 is operated as a Pennsylvania Business Trust and has
elected to be taxed as a partnership. Accordingly, no provision for income
taxes has been recorded in the accompanying financial statements.

(3) RETIREMENT SAVINGS PLAN

The Company sponsors a Retirement Savings Plan (the "Plan"), which qualifies
for treatment under section 401(k) of the Internal Revenue Code. Substantially
all full-time employees are eligible to participate by electing to contribute
1% to 15% of their gross pay to the Plan. Under the Plan, the Company matches
a portion of each employee's contribution up to certain limits. Each
employee's contribution is fully vested when contributed, and the Company's
matching contribution begins vesting after an employee has completed two years
of service and becomes fully vested after six years of service. For the years
ended December 31, 1995 and 1996, and the seven months ended July 31, 1997,
the Company's expense for the Plan was $6, $59 and $44, respectively.

(4) COMMITMENTS AND CONTINGENCIES

The Company leases land, office space and site space on towers and rooftops
through contracts that expire in various years through 2095. The Company has
purchase and renewal options and is committed to various escalation provisions
under certain of these leases. Rental expense under operating leases was $306,
$669 and $718 for the years ended December 31, 1995 and 1996, and the seven
months ended July 31, 1997, respectively. At July 31, 1997, minimum rental
commitments under operating leases are as follows:

The Company is involved in various claims and legal actions 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 combined financial position or results of
operations.

(5) CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations
of credit risk are primarily cash and cash equivalents and accounts
receivable. 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 western Pennsylvania. The Company mitigates
its concentrations of credit risk with respect to accounts receivable by
actively monitoring the creditworthiness of its customers. Historically, the
Company has not incurred any significant credit related losses.

For the year ended December 31, 1995, the Company recognized revenues from
two individual customers in the amount of $4,139 and $668. For the year ended
December 31, 1996, the Company recognized revenues from three individual
customers in the amount of $3,700, $2,600 and $1,400. For the seven months
ended July 31, 1997, the Company recognized revenues from three individual
customers in the amount of $4,784, $4,246 and $2,377.

(6) SUBSEQUENT EVENTS

In July 1997, the owners of CCM, CNS and CMS entered into an asset purchase
and merger agreement with Crown Castle International Corp. ("CCIC"). In August
1997, such agreement was amended and restated, and CCIC 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.

TEA GROUP INCORPORATED

NOTES TO FINANCIAL STATEMENTS

(IN THOUSANDS OF DOLLARS)

(1) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Basis of Presentation

TEA Group Incorporated (the "Company") provides services to the wireless
telecommunications and energy transmission industries. These services include
providing right-of-way, site acquisition, engineering design and drafting,
project management, and staff leasing to wireless telecommunications and
energy transmission companies in the United States and internationally.

Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities as of the date of the financial statements
and revenues and expenses for the reporting period to prepare these financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.

The financial statements for the three months ended March 31, 1996 and 1997
are unaudited; however, they include all adjustments (consisting only of
normal recurring adjustments) which, in the opinion of management, are
necessary to present fairly the results of operations and cash flows for the
three months ended March 31, 1996 and 1997. Accounting measurements at interim
dates inherently involve greater reliance on estimates than at year end. The
results of operations for the interim periods presented are not necessarily
indicative of the results to be expected for the entire year.

(b) Revenue Recognition

The Company's revenues are derived primarily from 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 priced contracts, and 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 to
estimated total contract costs. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined.

Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is provided over the estimated useful lives of the
assets on a straight-line basis. Leasehold improvements are amortized over the
shorter of their estimated useful lives or the remaining lease term. Property
and equipment are depreciated over the following estimated useful lives:

<TABLE>
<CAPTION>
YEARS
-----
<S> <C>
Leasehold improvements.............................................. 5
Office and computer equipment....................................... 5
Furniture and fixtures.............................................. 7
Computer software................................................... 5
</TABLE>

The Company adopted the provisions of Statement of Financial Accounting
Standards ("SFAS") 121, Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to Be Disposed Of, on January 1, 1996. This statement
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

F-45
<PAGE>

TEA GROUP INCORPORATED

NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

(IN THOUSANDS OF DOLLARS)
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair
value less costs to sell. Adoption of this statement did not have an impact on
the Company's financial statements.

(d) Income Taxes

The shareholders of the Company have elected to be taxed under the
Subchapter S Corporation provisions of the Internal Revenue Code. As a result
of this election, Federal and state income taxes related to the results of
operations of the Company are passed through to, and are the responsibility
of, the Company's shareholders. Accordingly, no provision for income taxes has
been recorded in the accompanying financial statements.

(e) Fair Value of Financial Instruments

The carrying value of the notes payable approximates the estimated fair
value for this instrument since it bears interest at a floating market rate.
The estimated fair values of the Company's financial instruments, along with
the carrying amounts of the related assets (liabilities), are as follows:

<TABLE>
<CAPTION>
DECEMBER 31, DECEMBER 31,
1995 1996
----------------- --------------
CARRYING FAIR CARRYING FAIR
AMOUNT VALUE AMOUNT VALUE
-------- ------- -------- -----
<S> <C> <C> <C> <C>
Cash....................................... $ 5 $ 5 $ -- $ --
Notes payable.............................. (2,733) (2,733) (107) (107)
</TABLE>

(2) NOTES PAYABLE

The Company has a revolving line of credit with a bank for working capital
purposes (as amended, the "Bank Line of Credit"). The Bank Line of Credit
provides for up to $5,000 of working capital borrowings and up to $200 of
borrowings for purchases of equipment. At December 31, 1996, outstanding
working capital borrowings under the Bank Line of Credit amounted to $107.
Borrowings are secured by the Company's receivables, property and equipment,
intangibles and cash balances, and bear interest at a rate per annum equal to
(i) the bank's prime rate or (ii) a Eurodollar interbank offered rate (LIBOR)
plus 2.45% (8.25% and 7.95%, respectively, at December 31, 1996). Interest is
payable monthly. The Bank Line of Credit requires the Company to maintain
certain financial covenants and places limitations on its ability to, among
other things, incur debt and liens, undertake transactions with affiliates and
make investments.

On July 30, 1997, the Bank Line of Credit was amended to decrease the
available borrowings to $3,000 and extend the maturity date to June 30, 1998.
Borrowings now bear interest at a rate per annum equal to LIBOR plus 2.7%
(8.39% at July 31, 1997). In addition, the amended Bank Line of Credit now
restricts the ability of the Company to pay dividends.

(3) COMMITMENTS

The Company has noncancelable operating leases for office space. Future
minimum lease payments under the operating leases with remaining terms of one
year or more at December 31, 1996 are summarized as follows:

<TABLE>

$963
====
</TABLE>

Rent expense under all cancelable and noncancelable operating leases for
1995 and 1996 was $459 and $608, respectively.

(4)EMPLOYEE BENEFIT PLAN

The Company maintains a 401(k) profit sharing and retirement plan (the
"Plan") for the benefit of all eligible employees. Employees may elect to
contribute up to 15% of their eligible compensation to the Plan. The Plan
provides for employer matching contributions at the discretion of the
Company's Board of Directors. The Company provided $66 and $29 in expense for
contributions for 1995 and 1996, respectively.

(5)RELATED PARTY TRANSACTIONS

Accounts receivable balances at December 31, 1995 and 1996 include
approximately $398 and $94, respectively, from an affiliated company related
to expenses incurred by the Company on behalf of the affiliated company.

(6) CONCENTRATIONS OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations
of credit risk are primarily cash and trade receivables. The Company mitigates
its risk with respect to cash 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 and energy transmission industries. The
Company mitigates its concentrations of credit risk with respect to trade
receivables by actively monitoring the creditworthiness of its customers. In
connection with a disputed receivable with a customer, the Company wrote off
$310 during 1996.

For the year ended December 31, 1995, the Company had five customers
representing 19%, 18%, 16%, 13% and 11% of net revenues, respectively. For the
year ended December 31, 1996, the Company had two customers which accounted
for 35% and 14% of net revenues, respectively, and one customer which
accounted for approximately 59% of accounts receivable at December 31, 1996.

(7)SUBSEQUENT EVENT

In July 1996, the Company, its shareholders, and certain affiliated
companies entered into an agreement with Crown Castle International Corp.
("CCIC") which provided CCIC with an option to acquire various ownership
interests in the Company. On May 12, 1997, CCIC acquired all of the Company's
common stock.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

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

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1 BASIS OF PREPARATION

As used in the financial statements and related notes, the terms "Castle
Transmission" or "the Group" refers to the operations of Castle Transmission
Services (Holdings) Ltd and its subsidiaries, Castle Transmission
International Ltd ("CTI") which is the successor business and Castle
Transmission (Finance) plc ("CTF"). The term "Home Service" refers to the
operations of the Home 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 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, for the three months ended June 30, 1997 and as of and for the six
months ended June 30, 1998 are unaudited; however, in the opinion

F-53
<PAGE>

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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 six month period ended June 30,
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

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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 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.

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.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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.

As a result of the completion of the fair value exercise this provision was
reduced by (Pounds)234,000 and a further provision was made of
(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
fees, was charged to the profit and loss account during the period from April
1, 1997 to December 31, 1997.

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.

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.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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.

18 ACQUISITION

On February 28, 1997 the Company acquired the entire share capital of CTI.
CTI had itself acquired the assets and liabilities of Home Service on February
27, 1997, with the intention of CTI's ensuing disposal to the Company.

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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.

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 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THE BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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.

Castle Transmission

The Shareholders of Castle Transmission are:

Crown Castle International Corp. ("CCIC", formerly Castle Tower Holding
Corp.), Candover Investments plc and funds managed by it ("Candover"),
TeleDiffusion de France International S.A ("TdF") and Berkshire Partners LLC
and funds managed by it ("Berkshire"). They are considered to be related
parties as they are the consortium who own 99 percent of the shares of the
Company.

Castle Transmission paid fees to shareholders in respect of expenses
incurred during the acquisition and success fees. Castle Transmission also has
management agreements with CCIC (for commercial and financial advice and
training and consultancy) and TdF (for technical advice and consulting), these
agreements run for five years from February 28, 1997. Fees are payable on the
basis of an annual fee for agreed services provided to Castle Transmission,
together with fees on a commercial arm's length basis for any additional
services provided. In addition Castle Transmission has agreed to reimburse
shareholders' expenses in relation to attendance at board meetings. The
amounts paid and accrued by the Company during the period were as follows:

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.

F-70
<PAGE>

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND
THF BBC HOME SERVICE TRANSMISSION BUSINESS

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

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 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 share options included within the unaudited
consolidated financial statements for the six months ended June 30, 1998 is
(Pounds) 1,935,000.

F-71

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND

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.

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.

(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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

(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.

Summary combined statements of cash flows for Castle Transmission prepared in
accordance with US GAAP are set out below:

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 attorney's 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 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 (filed
herewith as Exhibit 3.1) provide 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 or 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 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.

II-1
<PAGE>

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 Bylaws 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 Bylaws. 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 Bylaws or otherwise.

The Company's Bylaws 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 Bylaws 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 Bylaws 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 Bylaws 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 Bylaws 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

II-2
<PAGE>

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.

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

converted in February 1997).

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.
