The forwardlooking statements included in this presentation are based upon the current beliefs and expectations of the management of Protection One and are subject to certain risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Certain factors that could cause actual results to differ from those set forth in this presentation include: Protection One’s history of losses, which are likely to continue; failure to successfully integrate the business of Integrated Alarm Services Group, Inc.; principal and interest payment requirements of Protection One’s indebtedness; competition, including competition from companies that are larger than Protection One and have greater resources; losses of customers over time and difficulty acquiring new customers; changes in technology that may make Protection One’s services less attractive or obsolete or require significant expenditures to upgrade; the development of new services or service innovations by Protection One’s competitors; potential liability for failure to respond adequately to alarm activations; changes in management; the potential for environmental or man-made catastrophes in areas of high customer concentration; changes in conditions affecting the economy or security alarm monitoring service providers generally; and changes in federal, state or local government or other regulations or standards affecting Protection One’s operations.

Adjusted EBITDA Reconciliation Adjusted EBITDA is used by management in evaluating segment performance and allocating resources, and management believes it is used by many analysts following the security industry. This information should not be considered as an alternative to any measure of performance as promulgated under accounting principles generally accepted in the United States of America, such as loss before income taxes or cash flow from operations. Items excluded from Adjusted EBITDA are significant components in understanding and assessing the consolidated financial performance of the Company. See the table below for the reconciliation of Adjusted EBITDA to consolidated loss before income taxes. The Company’s calculation of Adjusted EBITDA may be different from the calculation used by other companies and comparability may be limited. Management believes that presentation of a non-GAAP financial measure such as Adjusted EBITDA is useful because it allows investors and management to evaluate and compare the Company’s operating results from period to period in a meaningful and consistent manner in addition to standard GAAP financial measures.

© 2008 Protection One, Inc . RMR Reconciliation Recurring Monthly Revenue (RMR) RMR is the sum of all the monthly revenue we are entitled to receive under contracts with customers in effect at the end of a period. 2007 (in millions) RMR at December 31 26.7 $ Amounts excluded from RMR: Amortization of deferred revenue 1.0 Other revenue (a) 3.0 Revenue (GAAP basis) December 30.7 January - November 317.2 Total period revenue 347.9 $ (a) Revenue that is not pursuant to periodic contractual billings. The Company believes the presentation of RMR is useful to investors because the measure is often used by investors and lenders to evaluate companies such as Protection One with recurring revenue streams. Management monitors RMR, among other things, to evaluate the Company’s ongoing performance. A reconciliation of RMR to Protection One, Inc.'s reported monitoring and related services revenue follows:
