Item 4.01(a)    Changes in Registrant’s Certifying Accountant 
  On July 9, 2007, Goodman & Company, L.L.P. (“Goodman”) notified Telos Corporation (the “Company”) that it will resign as the Company’s independent accountant effective July 24, 2007. Goodman stated that it intended to resign because its independence had been impaired. In particular, Goodman determined that it could no longer serve as the Company’s independent accountant because Seth W. Hamot and Andrew R. Siegel (collectively, the “Class D Directors”) had been elected to the Company’s Board of Directors effective June 18, 2007. 
  As previously disclosed, Costa Brava Partnership III, L.P., a holder of the Company’s 12% Cumulative Exchangeable Preferred Stock (“Costa Brava”), has filed a lawsuit in the Maryland Circuit Court in the City of Baltimore against the Company, its directors and certain of its officers. Costa Brava has also filed a civil action in the Virginia Circuit Court in the County of Fairfax against Goodman. Mr. Hamot is the Managing Member of Roark, Rearden & Hamot Capital Management, LLC (“RRHCM”), which is the investment manager to Costa Brava and also the President of Roark, Rearden & Hamot, LLC, which is the general partner of Costa Brava. Mr. Siegel is the Senior Vice President of RRHCM. The lawsuit in Maryland against the Company, its directors and certain of its officers and the lawsuit in Virginia against Goodman were each filed before the election of the Class D Directors to the Company’s Board. 
  The reports of Goodman regarding the Company’s financial statements for the fiscal years ended December 31, 2006 and December 31, 2005 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principle. During the Company’s two most recent fiscal years and through the date of this Form 8-K, the Company did not have any disagreement with Goodman on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of Goodman, would have caused Goodman to make reference thereto in their reports on the Company’s financial statements for such periods. In addition, there were no reportable events, as listed in Item 304(a)(1)(v) of Regulation S-K. 
  The Company has requested that Goodman reconsider its conclusion and review the Company’s interim financial statements that will be included in the Company’s Form 10-Q for the quarter ended June 30, 2007 based on the belief of the Company’s Audit Committee that Goodman’s independence has not been impaired. The Company has also begun interviewing accounting firms to serve as the Company’s independent accountant in the event that the Company and Goodman are unable to agree on Goodman’s continuation as the Company’s independent accountant. 
  Goodman was provided a copy of the above disclosures and was requested to furnish a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements.  |
