Carrier Challenges

• Backhaul Expense 15-25 of total carrier opex
  and growing
• Backhaul Expense Growth outstripping revenue
  growth significantly
• Reliability 50-80 cell site outages
  attributable to wired local loop
• Capacity Constraints Growth in voice and data
  traffic increasing required backhaul capacity
• Capacity Constraints 18 T1s per tower is the
  approximate capacity limit of existing copper
  (Source Stratsoft Research 2006)
• Technology Migration - Need to migrate from TDM
  (T1s) to Ethernet
• Scalability/Provisioning Time - Lengthy T-1
  provisioning times (4-12 weeks)

Site Level Economics

• Capex for single tenant site is approximately
  40,000
• Current T1 capacity per site is approximately
  21-28 T1s

20
Recent Capital Raise

• 402.5 million private placement closed on
  November 9 net proceeds of 390 million
• 69 million to be used for first two years of
  interest expense, leaving us with approximately
  321 million to fund network expansion in the 12
  existing markets and to selectively open up new
  markets, as well as for general corporate
  purposes
• De-risks the company and gives us the capital we
  need to deploy our networks and execute on our
  business model
• Accruing 9 interest annually, payable
  semi-annually
• To mature on November 15, 2012
• Initial conversion price of 8.29, a 15 premium
  over Oct. 26 closing price
• Conversion price may be reduced if certain
  conditions are not met
• Secured by nearly all of FiberTowers assets

Summary

• The backhaul market opportunity is estimated to
  grow from 3.8 billion in 2006 to 10.1 billion
  in 2010
• Market forces are leading to a perfect storm for
  microwave backhaul
• Recurring revenue from quality customers, low
  churn and high incremental contribution margin
  with each additional T1 equivalent and/or carrier
  added
• Through nationwide spectrum and strategic tower
  company relationships, FiberTower can rapidly
  deploy backhaul networks in metro, suburban and
  rural markets
• FiberTower is in a strong financial position to
  execute its plan
• FiberTower can provide a more scalable, reliable
  and cost-effective backhaul solution
