OPERATING THROUGH A FRAGILE ECONOMY

Impact on crime and police budgets “Recent research shows that economically motivated crimes like robbery and burglary tend to go up during recessions,” says Richard Rosenfeld, a professor of criminology and criminal justice at the University of Missouri-St. Louis. Parade Magazine, Feb. 8, 2009 The Retail Industry Leaders Association today released the Current Crime Trends Survey, revealing evidence that crimes against retailers are trending upward in correlation with the down economy. The Retail Industry Leaders Association, Dec. 9, 2008 Nearly half of the 233 police agencies surveyed since the collapse of the nation’s financial markets link increases in criminal offenses to the faltering economy, a new review by a law enforcement research group shows. USA TODAY, Jan. 27, 2009 As the recession forces people out of work and into desperate situations, communities large and small are seeing a spike in crime ranging from shoplifting to car breaks to burglaries. Boston.com, Feb. 5, 2009 The Police Executive Research Forum released a survey in January showing that 44 percent of police departments reported increases in crimes they believed could be attributed to the economic crisis. CNN.com, Feb. 24, 2009 While Wall Street grapples with its financial downpour, main street America is dealing with a potential perfect storm of crime. Tighter budgets for public safety services have resulted in fewer resources to combat crime at the local level. Imperial Valley News, Feb. 17, 2009

Recent Developments Protection One’s former parent, Westar Energy, included this disclosure in its 2008 10-K filed on Friday, Feb. 27th: “In April 2008, the IRS completed its examination of the federal income tax returns filed for years 2003 and 2004. In its examination report, the IRS did not approve our refund claim to change the original federal income tax characterization of the loss we incurred in 2004 on the sale of Protection One, Inc. (Protection One) from a capital loss to an ordinary loss. The characterization of the loss as capital or ordinary affects our ability to carryback and carryforward the loss to tax years in which the loss can be utilized. In June 2008, we filed a protest with the IRS Office of Appeals to pursue the re-characterization of the loss. In November 2008, we reached a tentative settlement with the IRS Office of Appeals (IRS Appeals Settlement) on the amount of the net capital loss and net operating loss carryforwards as of the end of December 31, 2004. This tentative settlement was subject to review by the Joint Committee on Taxation of the U.S. Congress. On December 22, 2008, we were notified that the Joint Committee on Taxation questioned the appropriateness of the settlement. We responded to the Joint Committee on Taxation’s questions and submitted our response on December 29, 2008. On January 14, 2009, the IRS notified us that the Joint Committee on Taxation had approved the IRS Appeals Settlement. Given the degree of uncertainty regarding this issue we were unable to conclude that realization of the benefit was more likely than not at December 31, 2008. Under the terms of our tax sharing agreement, we reimburse subsidiaries for current tax benefits used in our consolidated tax return. Under an agreement relating to the sale transaction, we will pay Protection One an amount equal to 50% of the net tax benefit (less certain adjustments) that we receive from the net operating loss carryforward arising from the sale. The recognition of this previously unrecognized tax benefit in accordance with the provisions of FIN 48 will result in a net earnings benefit of approximately $32.5 million. We have extended the statute of limitations for these years until September 30, 2009.” There can be no assurance regarding the amount or timing of any payment to Protection One.

Adjusted EBITDA Reconciliation A reconciliation of Adjusted EBITDA to Protection One, Inc.’s reported loss before income taxes for the nine months ended September 30, 2008 and the year ended December 31, 2007 is as follows (in millions): 9/30/2008 12/31/2007 Loss before income taxes Interest expense, net Amortization and depreciation expense Amortization of deferred cost in excess of amortization of deferred revenue Loss on retirement of debt Stock-based compensation expense Merger related severance & other (43) 36 50 23 13 1 1 81 (32) 47 62 24 - 2 4 107 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 above 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 the presentation of non-GAAP financial measures 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.

Net Debt Reconciliation Net Debt is utilized by management as a measure of the Company's financial leverage and the Company believes that investors also may find Net Debt to be helpful in evaluating the Company's financial leverage. This supplemental non-GAAP information should be viewed in conjunction with the Company's consolidated balance sheets in the Company's report on Form 10-Q for the period ended September 30, 2008.
