Our Risks Revenue and subscriber erosion Units in Service combined with the related Average Revenue Per Unit (ARPU) is what drives our revenue and thus our revenue erosion rate Subscriber erosion rates did improve in 2007 and in the first quarter of 2008, however there is no guarantee that we will be able to repeat that success this year or in the future We've been able to generate a reasonably good level of subscriber placements on a quarterly basis; unfortunately, those placements have been consistently outpaced by gross subscriber cancellations at a rate of about two cancels for every gross placement This trend is the single largest risk to our future cash flow generation potential While we've been able to keep product pricing relatively stable in recent years and even implement selected increases to part of our customer base in 2007, there is no assurance that ARPU levels will improve going forward

Our Risks The Federal Communications Commission (FCC) Back-Up Power Order (Order) Last October the FCC issued an Order requiring among other things that large commercial mobile radio service (CMRS) providers, including USA Mobility, have at least eight hours of back-up power at each transmission site to minimize communications outages during emergencies We believe that this Order is legally flawed in several respects FCC did not give proper notice that it was considering such a requirement FCC disregarded factors unique to paging, such as our simulcast high-powered network architecture, that make a nationwide back-up power requirement unnecessary In concert with other wireless providers and trade associations, we petitioned for an expedited review of the Order in January in the DC Circuit Court of Appeals The Order is currently under a Stay granted in conjunction with Sprint Nextel Corporation's appeal We continue to pursue our suit on its own merit

Our Risks Costs It has become increasingly difficult to reduce our operating costs at a pace in line with our declining revenue base in order to maintain cash flow margins Our ability to continue to generate incremental savings has become a major challenge as we have harvested much of the low hanging fruit Economies of scale are increasingly more difficult as we get smaller Going forward, the majority of our cost savings will be gained from network & site rent rationalization activities Competition We continue to face fierce competition from wireless technologies such as BlackBerry(r) and other broadband two-way voice and data carriers

The Future USA Mobility will continue to offer cost effective, mission critical wireless communications services to our valuable customer base We will continue to operate efficiently and focus on profitability and Free Cash Flow We will return our earnings to stockholders through cash distributions and/or stock repurchases How much, how long? - Its all about managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . managing between the lines . . . *$'s Returned in millions.
