Roam-In Business Model

•Definition:Roam-In Service

–Effectively allows customers of GSM carriers to “roam-in” to satellite coverage

–Requires GSM customers to purchase a satellite enabled handset

•Roam-In Business Model

–GSM carriers will pay a monthly recurring charge per subscriber and usage

–Introduced as an additional service feature from GSM operators, and would
appear on the customer’s bill from the carrier

–Satellite usage charges will appear as roaming charges on the customers bill

12

•Risk averse business and
consumers willing to pay a
premium for safety and peace of
mind

•For use primarily in emergency
situations

•Adventurous travelers to parks and
nature areas, leisure boaters,
ATV/4x4/snowmobilers, mountain
bikers…

•For use in emergencies and
occasional communications

•Need for communication and vertical
applications for business continuity
and in remote areas

•All enterprise markets, including
finance & insurance, transportation &
logistics, extractive industries, oil &
gas, agriculture, forestry, etc.

•Consumers and small business users
living/working in areas where
terrestrial coverage is poor

•For use for basic communication

Safety Conscious

Outdoor Adventurers

Industry/Enterprise

Rural Population

•First Responders, Public Safety
Personnel & Essential Mission Critical
Personnel

•Continuous coverage when terrestrial
networks are unavailable

Government & Public Safety

A number of wireless market segments would benefit from the addition of TerreStar
service capabilities

Addressable Wireless Market Segments

13

•At a $20 monthly premium, almost 20% of cellular
subscribers indicated an interest in purchasing integrated
cellular/satellite services

•This equates to a potential total addressable market size of
over 50M (270M US cellular market x 19.5% = 53M)

•10% of business cellular subscribers indicated they would
definitely purchase at a $20 premium

•Bottom-up approach to defining addressable market results
in 38M market size

•Achieving 38M market size depends on bringing equipment
costs down to no more than $50 premium over standard
cellular devices

•Earliest adopters will be government/public safety, industry
verticals, and outdoor adventurers
