Page 7 of 11 AMENDMENT NO. 4 to SCHEDULE 13D This amendment ("Amendment No. 4") amends the Schedule 13D previously filed on March 25, 2005, and amended by Amendment No. 1 filed on May 9, 2005 and further amended by Amendment No. 2 filed on June 6, 2005, and further amended by Amendment No. 3 filed on July 13, 2005 (collectively, the "Schedule"), by Costa Brava Partnership III, LP ("Costa Brava"), Roark, Rearden & Hamot, LLC ("Roark"), Seth W. Hamot ("Hamot"), White Bay Capital Management, LLC ("White Bay"), and Andrew R. Siegel ("Siegel") with the Securities and Exchange Commission with respect to the 12% Cumulative Exchangeable Redeemable Preferred Stock, $0.01 par value ("Redeemable Preferred Stock") of Telos Corporation, a Maryland corporation (the "Issuer"). All defined terms refer to terms defined herein or in the Schedule. This Amendment No. 4 speaks only as of its date. Costa Brava, Roark, Mr. Hamot, White Bay and Mr. Siegel are collectively referred to herein as the "Reporting Persons". The Schedule is amended only to the extent set forth below: ITEM 4 PURPOSE OF TRANSACTION Item 4. Purpose of Transaction appearing in the Schedule is hereby amended to add the following: On September 9, 2005, Warner Stevens L.L.P., as counsel to, and on behalf of, Costa Brava, sent a letter to the Issuer and to Corporation Trust Incorporated, the Issuer's registered agent for service of process in the State of Maryland (the "Demand Letter"). Attached to the Demand Letter was a draft complaint (the "Draft Complaint"), which Costa Brava is contemplating filing in the Circuit Court for Baltimore City in the State of Maryland. Through the Demand Letter, Costa Brava has demanded that the Issuer's Board of Directors immediately take the corrective steps enumerated in the Draft Complaint. Specifically, Costa Brava has demanded that the Issuer do the following: (1) Provide a full and complete accounting; (2) Cancel or prohibit the exercise of 1,310,000 stock options granted to John B. Wood, and recover $1,600,000 paid in cash bonuses to Mr. Wood; (3) Cancel or prohibit the exercise of 750,000 stock options granted to Michael P. Flaherty, and recover $992,792 paid in cash bonuses to Mr. Flaherty; (4) Cancel or prohibit the exercise of 742,000 stock options granted to Robert J. Marino, and recover $675,659 paid in cash bonuses to Mr. Marino; (5) Cancel or prohibit the exercise of 450,000 stock options granted to Edward L. Williams, and recover $906,000 paid in cash bonuses to Mr. Williams; (6) Cancel or prohibit the exercise of 450,000 stock options granted to John M. McDuffie, and recover $250,000 paid in cash bonuses to Mr. McDuffie; and (7) Recover $166,500 paid in cash bonuses to Richard Tracy. In the Demand Letter, to the extent these actions cannot be addressed informally, Costa Brava has demanded that the Issuer initiate a lawsuit to address and resolve the concerns enumerated in the Draft Complaint. While Costa Brava believes it had no obligation to make a formal demand before filing the Draft Complaint, nevertheless, Costa Brava made its formal demand through the Demand Letter in the event that a court should determine such a demand to be necessary. According to the Demand Letter, a refusal by the Issuer to take appropriate measures as enumerated in the Demand Letter no later than thirty (30) days from the Issuer's receipt thereof will result in Costa Brava pursuing appropriate legal and equitable relief.
Page 8 of 11 In addition, Costa Brava and the other Reporting Persons continue to review and reconsider their positions and formulate plans and proposals that may result in, or relate to, one or more of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Specifically, Costa Brava is considering filing the Draft Complaint, or some derivation thereof, on its own behalf to seek damages for breaches of fiduciary duty and extraordinary remedies such as injunctive relief, receivership proceedings and/or dissolution of the Issuer. As of the date of this Amendment No. 4, except as set forth above, and as otherwise set forth in the Schedule, none of the Reporting Persons has any present plan or intention which may result in, or relate to, any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
