Cost Efficiency Since we created USA Mobility in late 2004 through the merger of the #1 and #2 independent national paging companies, our margins and efficiency have continued to improve For 2010, 31 cents of each dollar of revenue generated turned into cash profit 11 Note: OCF Margin excludes Depreciation, Amortization & Accretion; Goodwill Impairment; Capital Expense. Annual Operating Cash Flow Per Average FTE in 000's Operating Cash Flow Margin EBITDA Margin

Our Strategy Has Worked Faced with declining subscribers and revenue, we have met enormous challenges with respect to managing the business, integrating and extracting costs For the past five years annual operating expenses have been reduced at a higher rate than the rate of annual revenue decline We have produced significant free cash flow, expanded our margins and planned for the future 12 *Operating Cash Flow (OCF) excludes Depreciation, Amortization & Accretion; Goodwill Impairment; Capital Expense. **Operating Expense excludes Depreciation, Amortization & Accretion; Goodwill Impairment. Revenue Reduction Operating Expense** Reduction (Millions)

Past Results & Outlook The acquisition of Amcom Software presents significant upside opportunities for our stockholders and customers 13 *Actual cash invested exclusive of debt. Over the past six years it has become clear that paging revenues will continue to decline, pressuring future margins and our ability to return cash to our share base We felt strongly that our valuable franchise in Healthcare, Government and Large Enterprise could generate additional long-term value if we found a target acquisition that fit well with what we do (Millions) Create long-term value & return excess capital to stockholders

Amcom Transaction Rationale Identical Market Segment Focus - Healthcare, Government, Large Enterprise Complimentary products, services and cross-selling opportunities "Sticky" systems solutions with high maintenance renewal rates Strong growth profile combined with high margins Immediately accretive to Cash Flow and EPS Strong disciplined Management Team Operating as a separate subsidiary No business interruption/costs or integration issues Long term revenue and cash flow stabilization, leading to growth Utilization of significant tax assets Maintain dividend distributions while conservatively capitalized - expect to be net debt free by year end 2011 14

Hospitals Need Solutions 18 Inadequate communication is the main cause of sentinel events in hospitals(1) Amcom customer experiences illustrate need for rapid, more automated communications Lack of coordinated response to patients in distress Difficulty reaching the appropriate clinician Inaccurate on-call schedules contribute to improper contacts Slow caregiver response to aid requests (1) Improving America's Hospitals: The Joint Commission's Annual Report on Quality and Safety 2007

Hospitals Need Increased Productivity and Reduced Costs Improving productivity and reducing costs are imperatives Amcom customer experiences illustrate need for reduced costs and increased productivity Simple, mundane calls consume operator bandwidth Dispersed call centers have heavy staffing overhead Tracking down clinicians consumes caregiver time Patient requests and growth in alarms increases transit time What are the major communication issues which impact a nurse's productivity (% of respondents answering yes)? Forrester Research If more sophisticated communication enabled instant access to experts, how much time could this save the typical nurse? 19

Smartphone Data 20 What will they do with these? Physician reference Receive clinical information EKG Images Communicate Pager replacement Direct connect Dictate Administration 70% of hospitals that Amcom surveyed (customers & prospects) plan to move from some pagers to smartphones Source: Jupiter Research

Separates critical messages from less important emails and SMS messages Full audit trail of delivery and read receipts Active acknowledgement of message and free-form text response Huge interest from installed base and prospects 21 Smartphone Messaging: Amcom Mobile Connect
