FORWARD LOOKING INFORMATION

Certain Risks and Uncertainties
- -------------------------------

*    Demand for towers and wireless communication sites may be lower or slower
     than anticipated for numerous reasons, including reduced carrier expansion,
     carrier consolidation, network sharing, technology development, or RF
     health concerns

*    Demand for wireless communications may be lower or slower than anticipated
     for numerous reasons, including slow customer adoption rates of 2.5/3G and
     other technologies

*    Our strategy may be more difficult to implement than anticipated due to
     financial or other reasons, including our significant amount of
     indebtedness, or reduced cash flow as a result of reduced revenues or
     increased operating costs, interest rates or capital expenditures

FINANCIAL STRATEGY
- ------------------

*  Capital Allocation
   -  Debt service (i.e. cash interest)
   -  Tower builds & improvements
   -  Service offerings (e.g., backhaul)

*  Liquidity
   -  Fully-funded for existing business plan
   -  Adequate covenant headroom

*  Capital Structure
   -  Reduce the cost of capital through operating performance and de-leveraging
      the balance sheet



SLIDE 11
THE PATH TO FREE CASH FLOW IN 2004


Objective:  Achieve positive free cash flow after interest and capital
expenditures in 2004 with existing financial resources while significantly de-
leveraging the capital structure.


Solution:  Continued execution of the core tower leasing business and allocation
of capital spending to value-enhancing activities within the constraints
imposed.

CURRENT STATE OF MIND

*  Wireless industry growth slowing due to wireless data delays
*  Current coverage is sufficient
*  2.5/3G technologies reduce need for more sites
*  Capital constraints may result in carriers waiting
*  Capacity problems can be fixed with equipment and without sites
*  Spectrum relief & removal of spectrum cap means fewer sites

CURRENT REALITY

*  Usage growth is sky-rocketing
*  Coverage is work in progress
*  Technical realities demand more sites to improve performance
   -  Spectrum constraints in a highly competitive environment
   -  TDMA/GSM spectral efficiency near maximum potential
   -  New PCS network build-outs
   -  In-building penetration coverage
   -  Additional 2.5/3G packet data network loading

NETWORK COVERAGE ISSUES

Situation
- ---------
*  Cellular coverage still incomplete
*  PCS coverage (as % of population)... less complete
*  PCS frequencies don't propagate as well as cellular
*  Lack of coverage is number one driver of churn and adds
*  Huge financial incentive to prevent churn

Implication
- -----------
*  PCS carriers will aggressively add coverage sites

NYC CASE STUDY

[The following is a description of graphical materials]

Correlating factors to churn
- ----------------------------
Dropped Calls      (higher correlation)
Customer Service
Coverage
Network Quality
Blocked Calls      (lower correlation)

[Graphic entitled "Net Q Satisfaction vs. Churn: New York" showing increased WSI
Net Q Score leads to lower churn rate.  Chart states "Increase relative
saturation by 14% decreases churn by 1.25%"]

*  For a 20% market player in NYC with 1.2 million subscribers, reduced churn
   equals greater than $65 million in annual cost savings.

*  At $350,000 per cell site, carrier could build 185 new cell sites per year,
   further reducing churn.


SLIDE 29
FINANCIAL MAGNITUDE OF CHURN

*  Impact to industry of a 1.25% reduction in churn: $6.65 billion savings

*  $6.65 billion could build 19,000 cell sites per year at $350k per site

(Source Calc: 123.2  million subscribers x 1.25% x 12 months per year  x $ 360
per CPGA)


SLIDE 30
RESULT

*  Financial realities for carriers make network performance #1 priority

*  Significant percentage of carrier expenditure will be based on site
   development

SLIDE 32
TOWER SITE DEMAND PROJECTIONS

*  What is the future cell site density for 2G likely to be?
*  Answers can be proxied by analysis of available metrics:
   -  Drive test data
      -  Dropped calls, call quality problems, and no service areas
      -  Estimate of operators' cell density
   -  Demographic proxies
   -  Scanning receivers (customer churn)
   -  Switch statistics (not available to tower companies)


SLIDE 33
TOWER SITE DEMAND PROJECTIONS

*  If we consider 3G high speed data, then cell site density can be projected
   based on one key assumption:

WIRELESS DATA: 3G

Relation to cell site density . . .

[Graphic showing higher bits/HZ technologies require smaller cell sites]

Increases in bits/HZ throughput requires smaller cell sites


SLIDE 36
WIRELESS DATA

*  All of today's systems were designed for voice (12.2 KBPS) and will require
   additional sites to provide ubiquitous high speed data.

*  Three times the number of cell sites will be required, unless:
   -  Operator elects to accept lower speed data in marginal areas
   -  Certain technologies can improve radio link quality "enough" to support
      lower speed data.
