PART 1 Item 1. Business History and Introduction Founded in 1968, Telos Corporation ("Telos" or the "Company") delivers enterprise security and integration solutions and services to customers in the U. S. Government and industry. During 2001, America and Telos' largest customer, the U.S. Government, changed forever in terms of their need for an increase in reliable and secure information and communication. Telos solutions address critical needs in the areas of secure wireless networking, secure messaging, secure local area networks ("LAN") data integration and enterprise risk management. Since 1996, Telos has identified and sold a number of business units that were not a part of its strategic direction. These businesses were: Telos Consulting Services, Telos Information Systems, and Telos Field Engineering. In 1999, Enterworks was separately funded and deconsolidated from Telos. Telos now owns 23.1% of Enterworks. In 2000, Telos contributed the net assets of its Ft. Sill operation to a new joint venture with outside investors, resulting in a 50% ownership in TelosOK. These dispositions and ventures, as well as operating cash flows, have enabled Telos to reduce corporate indebtedness from a high of $56.9 million in 1997 to $20.6 million in 2001. Reportable Operating Segments During 2001, Telos provided its business solutions through three operating segments: the Products Group, Systems and Support Services Group (the "Services Group"), and its wholly owned subsidiary, Xacta Corporation. Products Group The Company's Products Group delivers solutions that combine information technology products and services to solve customer problems. For 2001, the Products Group generated revenue of $96.3 million, up 9.7% from 2000. This Group represents 56.6% of the Company's reported consolidated revenue for 2001. Customers of the Products Group include agencies of the U.S. Government such as: military services, Defense Agencies, Treasury Department, U.S. Courts and others. Solutions from the Products Group consist of a combination of commercial-off-the-shelf ("COTS") products from major original equipment manufacturers ("OEMs"), Telos proprietary products, Telos and subcontractor services and Telos proprietary practices. For example, the Products Group sells secure wireless networking and secure messaging solutions. Telos' secure wireless networking solutions allow customers to securely access databases from non-networked locations so that they can perform a variety of tasks safely. Telos' secure messaging solution is known as the Automated Message Handling System ("AMHS") and is a standard within the Department of Defense. The AMHS allows users to securely access, send, search, and profile message traffic. Services Group The Company's Services Group provides post-deployment and post-production software and systems development and support services including technology insertion, systems redesign and software re-engineering. The Services Group's largest customer is the U.S. Army's Communications and Electronics Command ("CECOM"). The Services Group has approximately 228 personnel. Of all tasks performed by this Group, 96.9% of the tasks performed are on a time and materials basis with the remaining 3.1% being performed by subcontractors on a fixed price basis. For 2001, the Services Group generated revenue of $60.4 million, up 24.7% from 2000. The Group represents 35.5% of the Company's consolidated revenue for 2001. The Services Group's principal operations are located at Fort Monmouth, NJ and Fort Sill, OK. Since, 1983, the Services Group at Fort Monmouth has supported approximately 80 tactical land systems and satellite communications systems for CECOM's Research, Development and Engineering Center. During 2001, Telos and its partners organized a joint venture and were awarded a contract with a ceiling of approximately $1.4 billion over 10 years. The Services Group at Fort Monmouth achieved a software development assurance of Level 3 based on the Software Engineering Institute's (SEI) capability maturity model for software (CMM). Since 1977, the Services Group at Ft. Sill has developed 93 fire support systems and 177 major systems upgrades, totaling more than 11 million lines of code, using nine different programming languages for CECOM's Fire Support Software Engineering Center. During 2000, Telos contributed its Ft. Sill operation to a newly created entity, Telos-OK, in return for a 50% ownership, cash and other consideration. During 2001, Telos-OK teamed with United Defense, LP in support of the US Army's Crusader program and with Raytheon on the US Army's Advanced Field Artillery Tactical Data System ("AFATDS") program. Telos-OK has achieved SEI CMM Level 4 for software development assurance. Results from the Services Group at Ft. Sill were included in Telos' financial results until its deconsolidation in July 2000 (see Note 3 to the Consolidated Financial Statements). Since that time, the Company remains as the prime contractor on the Ft. Sill contract because the contract has yet to be successfully novated by the government. Therefore, in accordance with generally accepted accounting principles of the United States of America, the revenues and related expenses for this contract are included in their respective captions in the Company's financial statements. These "pass-through" revenues and related expenses reported by the Company result in zero profit to the Company. The Company anticipates this contract to be novated in the first half of 2002. The TFE division was part of the Systems and Support Services Group prior to its sale in 1999 (See Note 5 to the Consolidated Financial Statements). Xacta Corporation Xacta develops enterprise risk management software to help organizations to proactively manage and monitor the security of their network environments in accordance with internationally recognized industry and security standards. For 2001, Xacta generated revenue of $13.6 million, up 49.3% from 2000. This Group represents 7.9% of the Company's consolidated revenue for 2001. Xacta currently sells its solutions to agencies of the U.S. Government as well as credit unions. Xacta has developed and is selling two products: Xacta Web C&A and Xacta Commerce Trust. Xacta Web C&A automates the rigorous and time-consuming process of security certification and accreditation. Xacta Web C&A simplifies certification and accreditation by guiding users through a step-by-step process which determines the customer's information security posture and assesses system and network configuration compliance with applicable regulations, standards, and industry best practices and processes. With Xacta Commerce Trust, organizations are able to perform holistic security risk management on a continuous basis in accordance with internationally recognized industry standards and best practices. Revenue by Major Market and Significant Customers Revenue by major market for the Company is as follows: Percentage of total consolidated revenue for --------------------------------------------- 2001 2000 1999 ---- ---- ---- Federal government 97.7% 96.2% 92.8% Commercial 2.3 3.8 5.9 State and local governments -- -- 1.3 ---- ---- --- Total 100.0% 100.0% 100.0% ====== ====== ====== Total consolidated revenue derived from the federal government for 2001 includes 58.7% of revenue from contracts with the United States Army, 6.9% of revenue from contracts with the United States Air Force, 3.7% of revenue from contracts with the United Sates Navy, 11.7% of revenue with other Department of Defense customers, and 13.5% of revenue from the Federal Judicial branch. Competition The segments of the information services industry in which the Company operates are highly fragmented with no single company or small group of companies in a dominant position. Some of the large competitors offer services in a number of markets which overlap many of the same areas in which the Company offers services, while certain companies are focused on only one or a few of these markets. The firms that compete with the Company are computer services firms, applications software companies and consulting firms, as well as the computer service arms of computer manufacturing companies and defense and aerospace firms. Thousands of firms fall into these categories. As the Company becomes more focused on network-enabled enterprise computing, the competition shifts to include companies that perform enterprise integration for large and complex information technology environments. In addition, the internal staffs of client organizations, non-profit federal contract research centers and universities are competitors of the Company. The Company believes that the principal competitive factors in the segments of the information and network technology market in which it competes include project management capability, technical expertise, reputation for providing quality service, and price. The Company believes its technical competence in computer engineering, systems software, engineering, and system and network integration will enable it to compete favorably in the information and network technology market. Employees The Company employed 625 persons as of December 31, 2001. The services the Company provides require proficiency in many fields, such as computer science, mathematics, physics, engineering, operations research, economics, and business administration. Of the total Company personnel, 228 provide Systems and Support Services, 159 provide Systems Integration (Products) Services, and 128 work for the Company's Xacta subsidiary. An additional 110 employees provide corporate and business services functions. Backlog Many of the Company's contracts with the U.S. Government are funded by the procuring government agency from year to year, primarily based upon the government's fiscal requirements. This results in two different categories of backlog: funded and unfunded. Total backlog consists of the aggregate contract revenues remaining to be earned by the Company at a given time over the life of its contracts, whether or not funded. Funded backlog consists of the aggregate contract revenues remaining to be earned by the Company at a given time, but only to the extent, in the case of government contracts, funded by a procuring government agency and allotted to the contracts. Unfunded backlog is the difference between total backlog and funded backlog. Included in unfunded backlog are revenues which may be earned only if customers exercise delivery orders and/or renewal options to continue existing contracts. A number of contracts undertaken by the Company extend beyond one year and, accordingly, portions of contracts are carried forward from one year to the next as part of the backlog. Because many factors affect the scheduling and continuation of projects, no assurance can be given as to when revenue will be realized on projects included in the Company's backlog. At December 31, 2001 and 2000, the Company had total backlog from existing contracts of approximately $830.0 million and $124.4 million, respectively. This is the maximum value of additional future orders for systems, products, maintenance and other support services presently allowable under those contracts, including renewal options available on the contracts if exercised by the client, over periods extending up to seven years. The increase in total backlog is primarily attributable to the dual award of the US Army CECOM SEC contract to the Company's 50% owned joint venture, ITel Solutions. The Company will be a subcontractor to this joint venture, and estimates upon the successful award of competing task orders total backlog up to approximately $700 million. Approximately $28 million and $43 million of the total was funded backlog at December 31, 2001 and 2000, respectively. While backlog remains a measurement consideration, in recent years the Company, as well as other federal contractors, experienced a change in the manner in which the federal government procures equipment and services. These procurement changes include the growth in the use of General Services Administration ("GSA") schedules which allow agencies of the federal government to purchase significant amounts of equipment and services. The use of the GSA schedules results in a significantly shorter and much more flexible procurement cycle, as well as increased competition as many companies hold such schedules. Along with the GSA schedules, the federal government is awarding a large number of omnibus contracts with multiple awardees. These contracts generally require extensive marketing efforts by the awardees to procure business. The use of GSA schedules and omnibus contracts, while generally not providing immediate backlog, provide areas of growth that the Company continues to aggressively pursue. Overview of 2001 During 2001, the Company continued to focus on its commitment to creating unique, value added solutions, and reducing corporate indebtedness. The following paragraphs illustrate several examples of how. The Company's Services Group created ITel Solutions, a joint venture between Telos and L3/Ilex. ITel Solutions was awarded a dual contract to provide systems and software engineering support to CECOM. The award has a potential value of approximately $1.4 billion over 10 years. Under this dual award contract, ITel Solutions will compete for the award of tasks under the contract. Telos has also created value added solutions through its wholly-owned subsidiary, Xacta. There has never been a stronger need for reliable and secure communication. Xacta provides solutions to both Government and commercial customers to handle certain of these critical needs. Specifically, Xacta solutions help organizations proactively manage and monitor the security of their network environments in accordance with internationally recognized information security and privacy standards, regulations, guidelines and industry best practices. The Company's Products Group continues to better serve its customers with innovative product offerings, and as a result has experienced increased order volume and profitability in 2001. For example, the Products Group sells secure wireless networking and secure messaging solutions. Telos' secure wireless networking solutions allow customers to securely access databases from non-networked locations so that they can perform a variety of tasks safely. Telos' secure messaging solution is known as the Automated Message Handling System ("AMHS") and is a standard within the Department of Defense. The AMHS allows users to securely access, send, search, and profile message traffic. The Company made significant strides in reducing corporate indebtedness in 2001. The Company's term facility balance has been reduced by approximately 50% from the 2000 balance due to cash generation from operations. The Company was able to retire one of its Series C Subordinated Notes in 2001 and negotiated extensions of all its Series B and Series C Subordinated Notes and its Senior Redeemable Preferred Stock to May of 2003. The Company did not receive its anticipated volume of orders at the end of the federal government year (the federal government fiscal year ends September 30). In addition, the 2002 government budget approval was also delayed by several months. These two issues caused the Company to experience a decline in sales from the fourth quarter of 2001 compared to the fourth quarter of 2000.

Item 2. Properties The Company leases 191,700 square feet of space in Ashburn, Virginia for its corporate headquarters, integration facility, and primary service depot. This lease expires in March 2016, with a ten-year extension available at the Company's option. This facility supports all three of the Company's operating segments. The Company subleases 21,816 rentable square feet of space at its Ashburn, Virginia facility to its affiliate, Enterworks, Inc. for its corporate headquarters and operating segments. This sublease will expire on March 31, 2003 unless a renewal of the sublease is reached by mutual agreement between the Company and Enterworks. The Company leases additional space for regional contract work sites, training and sales offices in 5 separate facilities located in California, New Jersey, the District of Columbia and Europe under various leases, which expire on various dates through March of 2006. Item 3. Legal Proceedings The Company is a party to various lawsuits arising in the ordinary course of business. In the opinion of management, while the results of litigation cannot be predicted with certainty, the final outcome of such matters will not have a material adverse effect on the Company's consolidated financial position, results of operations or of cash flows. Item 4. Submission of Matters to a Vote of Security Holders The Company's annual meeting of common shareholders was held on November 6, 2001. The only matter set forth in the meeting was the election of directors. The shareholders of the common stock necessary to constitute a quorum were present either in person or represented by proxy or attorney. Dr. Fred Charles Ikle, John B. Wood, Norman P. Byers, Dr. Stephen D. Bryen, and David S. Aldrich were elected to a term of approximately one year, a term to expire at the next annual meeting of shareholders upon the election of their successors. Effective March 20, 2002, Dr. Bryen resigned as a proxy holder and Director. With regards to the holders of the 12% Cumulative Exchangeable Preferred Stock, shareholders of such stock necessary to constitute a quorum were not present and, therefore, the nominations of Malcolm M.B. Sterrett and Geoffrey B. Baker were not considered. Subsequent to the shareholders meeting, Malcolm M.B. Sterrett, an incumbent director, appointed Geoffrey B. Baker to fill the term of John C. Boland, who resigned on October 2, 2001. Mr. Sterrett and Mr. Baker's terms are for a period of one year, a term to expire at the next annual meeting of shareholders upon the election of their successors. Such appointment was consistent with Article Fifth (C)7(b)(vi) of the Company's Articles of Amendment and Restatement.

PART II Item 5. Market for the Registrant's Common Equity and Related Stockholder Matters No public market exists for the Company's Class A or Class B Common Stock. As of March 1, 2002, there were 84 holders of the Company's Class A Common Stock and 4 holders of the Company's Class B Common Stock. Item 6.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations General During 2001, the Company continued to focus on its commitment to creating unique, value added solutions, and reducing corporate indebtedness. The following paragraphs illustrate several examples of how. The Company's Services Group created ITel Solutions, a joint venture between Telos and L3/Ilex. ITel Solutions was awarded a dual contract to provide systems and software engineering support to CECOM. The award has a potential value of approximately $1.4 billion over 10 years. Under this dual award contract, ITel Solutions will compete for the award of tasks under the contract. Telos has also created value added solutions through its wholly-owned subsidiary, Xacta.

Telos' secure wireless networking solutions allow customers to securely access databases from non-networked locations so that they can perform a variety of tasks safely. Telos' secure messaging solution is known as the Automated Message Handling System ("AMHS") and is a standard within the Department of Defense. The AMHS allows users to securely access, send, search, and profile message traffic. The Company made significant strides in reducing corporate indebtedness in 2001. The Company's term facility balance has been reduced by approximately 50% from the 2000 balance due to cash generation from operations. The Company was able to retire one of its Series C Subordinated Notes in 2001 and negotiated extensions of all its Series B and Series C Subordinated Notes and its Senior Redeemable Preferred Stock to May of 2003. The Company did not receive its anticipated volume of orders at the end of the federal government year (the federal government fiscal year ends September 30). In addition, the 2002 government budget approval was also delayed by several months. These two issues caused the Company to experience a decline in sales from the fourth quarter of 2001 compared to the fourth quarter of 2000. During 2001, the Company experienced increases in revenue and profitability. Revenue increased $25.0 million, or 17.2%, as compared to 2000. Approximately $8.5 million of this increase was attributable to the Company's Products Group, which experienced increased sales from its traditional contracts with the federal government such as the Infrastructure Solutions I ("IS-1") contract, the Realtime Automated Personnel Identification System Contract ("RAPIDS"), and the Company's contracts serving the US Courts ("US Courts"). The increase in sales was also attributable to the pass-through sales from the Company's prime relationship on the Ft. Sill Contract, which resulted in increased sales of $12.0 million. This contract was contributed to TelosOK in July 2000, however, the Company remains as the prime contractor until the contract is successfully novated by the government. The Company anticipates this novation to occur in the first half of 2002. The Xacta Group also experienced an increase in revenue of $4.5 million, mostly due to increased sales of its information security products and solutions. Operating income for 2001 was $2.3 million, as compared to an operating income of $1.2 million in 2000. Profitability increased principally as a result of increased sales volume from all three Groups, coupled with improved profits under the Company's traditional businesses and its information security channel business in its Products Group as well as increased margins in its Xacta subsidiary. During 2000, the Company's revenue and profitability decreased as compared to 1999. Revenue decreased $26.1 million, or 15.2%. Approximately $24.3 million of this decrease was attributable to the sale of TFE in 1999. Approximately $11.5 million of this decline is due to the effects of the 2000 deconsolidation of Ft. Sill operations, which presents the pre-transaction results from operations of Ft. Sill in a single line item entitled "Equity in Net Earnings of TelosOK". Operating profit for 2000 was $1.2 million, as compared to an operating profit of $2.2 million in 1999. Operating profitability declined principally as a result of the sale of TFE in 1999 the impact of which was approximately $3.9 million, and the deconsolidation of Ft. Sill of approximately $1.4 million, as well as employee costs related to certain severance agreements resulting in a $1.2 million charge to earnings in fiscal 2000. Approximately 97.7% of the Company's total revenues in 2001 were attributable to contracts with the federal government. The Company's revenues are generated from a number of contract vehicles. In general, the Company believes its contract portfolio is characterized as having low to moderate financial risk as the Company has limited long-term fixed price development contracts. The Company's firm fixed price contracts consist principally of contracts for the purchase of computer equipment at established contract prices or contracts for certification and accreditation services offerings. The Company's time and material contracts generally allow the pass-through of allowable costs plus a profit margin. For 2001, revenue by contract type was as follows: time and materials, 41.2%; firm fixed price, 58.3%; other, 0.5%. While the Company has not experienced any significant recent terminations or renegotiations, government contracts may be terminated or renegotiated at any time at the convenience of the government.

Sales, gross profit and gross margin by market segment for the periods designated below are as follows: (dollar amounts in thousands) Year Ended December 31, ----------------------- 2001 2000 1999 ---- ---- ---- Revenue: Systems and Support Services $ 60,402 $ 48,429 $ 77,701 Products 96,301 87,799 89,261 Xacta 13,558 9,082 4,402 ------ ------ ------ Total $ 170,261 $ 145,310 $ 171,364 ======= ======= ======= Gross Profit: Systems and Support Services $ 5,261 $ 5,278 $ 11,768 Products 17,027 13,474 7,169 Xacta 4,932 2,530 1,211 ------ ----- ----- Total $ 27,220 $ 21,282 $ 20,148 ====== ======= ========= Gross Margin: Systems and Support Services 8.7% 10.9% 15.1% Products 17.7% 15.3% 8.0% Xacta 36.4% 27.9% 27.5% Total 16.0% 14.6% 11.8% Results of Operations Sales increased $25.0 million or 17.2% to $170.3 million for the year ended December 31, 2001, from $145.3 million for the comparable 2000 period. The increase for the period includes an $8.5 million increase in Products' sales, an increase of $12.0 million in Systems and Support Services sales, and an increase of $4.5 million in Xacta revenue. This increase in the revenue is primarily due to the increases in revenue from the Products Group traditional businesses as well as the pass-through sales contract as mentioned above. These increases were enhanced by increased sales under the Information Security product line of $4.5 million. Cost of sales was 84.0% of sales for the year ended December 31, 2001, as compared to 85.4% for the same period in 2000. The reduction in cost of sales as a percentage of sales is primarily attributable to increased profits realized on Products Group traditional contracts, such as IS-1 and US Courts, and from increased profits from sales of the Company's information security product line. Gross profit increased $5.9 million in the period to $27.2 million in 2001 from $21.3 million in 2000. The gross margin was 16.0% for the twelve-month period of 2001 as compared to 14.6% for the comparable period of 2000. Selling, general, and administrative expense ("SG&A") increased by approximately $4.8 million or 24.4%, to $24.6 million in the year ended December 31, 2001 from $19.8 million in the comparable period of 2000, which is primarily attributable to the Company's increased investment in the product development, sales and marketing effort for Xacta. The increase is also due to an approximately $600,000 one-time write-off of an investment made in an international joint venture, and a $1.8 million reserve recorded against the Enterworks notes receivable held by the Company (See Note 2 to the Financial Statements). SG&A as a percentage of revenues for the twelve-month period ended December 31, 2001 increased to 14.4% from 13.6% compared to the same period in 2000. Goodwill amortization expense decreased $62,000 for the comparative year-end periods of 2001 and 2000. The reduction is exclusively due to the goodwill transfer associated with the TelosOK transaction. The operating income of the Company increased by $1.1 million to approximately $2.3 million in the year ended December 31, 2001 from an operating income of $1.2 million in the comparable 2000 period. The increase in operating profit is mostly attributable to the increases in gross profit discussed above. In order to present the statement of operations in accordance with APF 18, the Company's share of Enterworks, Inc. was presented in one line item "Equity in net losses in Enterworks" due to the deconsolidation of Enterworks on December 30, 1999. (See Note 4 to the consolidated financial statements). In 2000 and 2001, Enterworks continued to recognize losses, accordingly no adjustments to earnings of the Company were made in fiscal 2000 and 2001 related to the Enterworks investment because the balance of the Company's investment in Enterworks was $0. In order to present the statement of operations in accordance with APB 18, the revenues and costs of sales for the Ft. Sill operation contributed to TelosOK were presented in one line item "Equity in Net Earnings of TelosOK" for the year ended December 31, 2000 (See Note 3). For 2000, Equity in Net Earnings of TelosOK was approximately $2.3 million. The Company, under APB 18, is unable to recognize its pro rata share of the income generated by TelosOK for 2001, as the Company's capital account for TelosOK is negative. Interest expense decreased approximately $700,000 to $4.1 million in 2001 from approximately $4.8 million in the comparable 2000 period. These decreases are primarily due to decreased debt levels and declining interest rates in 2001 compared to 2000. The Company recorded an income tax benefit for the year ended December 31, 2001 of $996,000. This tax benefit was principally due to the net loss generated by the Company. The Company's net deferred tax assets totaled $8.3 million at December 31, 2001. Failure to achieve forecasted taxable income may affect the ultimate realization of the net deferred tax assets. Management believes the Company will generate taxable income in excess of operating losses sufficient in amounts to realize the net deferred tax assets. The Company recorded an income tax provision of approximately $600,000 for the year ended December 31, 2000. The provision incurred was a result of the taxable gain generated from proceeds received from the contribution of assets to TelosOK in July 2000 (see Note 3). Years ended December 31, 2000 and 1999 Sales decreased $26.1 million or 15.2% to $145.3 million for the year ended December 31, 2000, from $171.4 million for the comparable 1999 period. The decrease includes a $1.5 million decrease in Products' sales and a $29.3 million decrease in Systems and Support Services sales, partially offset by an increase of $4.7 million in Xacta revenue. This decrease in revenue is primarily due to the loss of revenue from the TFE division, which was sold in September 1999. The TFE division generated sales of $24.3 million for the Company prior to being sold. The decline in revenue was also partially attributable to the deconsolidation of Ft. Sill revenue in 2000. These decreases were slightly offset by increased sales under the Company's information security product line of $4.7 million. Cost of sales was 85.4% of sales for the year ended December 31, 2000, as compared to 88.2% for the same period in 1999. The decrease in cost of sales as a percentage of sales is primarily attributable to increased profits realized under certain Products contracts including but not limited to IS-1, ATWCS and Rapids. The decline in cost of sales as a percentage of sales is also due to increased profits from the Company's information security product line in its Xacta Group. Gross profit increased approximately $1.1 million to $21.3 million in 2000 from $20.2 million in 1999. Gross margin was 14.6% for 2000 as compared to 11.8% for the same period of 1999. The increase in gross margin was attributable to the cost of sales decreases explained above. Selling, general, and administrative expense ("SG&A") increased by approximately $2.3 million or 13.4%, to $19.8 million for the year ended December 31, 2000 from $17.5 million in the comparable period of 1999. This increase is due primarily to the Company's increased investment in its Xacta group, as well as increased expenses related to two severance agreements. SG&A as a percentage of revenues increased to 13.6% for the year ended December 31, 2000 from 10.2% in the comparable 1999 period. Goodwill amortization expense decreased approximately $200,000 for the comparative twelve-month period of 2000 from 1999. This reduction is due to a decrease in the goodwill balance from write-offs associated with the sale of TFE in the third quarter 1999 and the asset transfer from the Ft. Sill transaction in the third quarter of 2000. The operating income of the Company decreased by $1.0 million to $1.2 million in the year ended December 31, 2000 from $2.2 million in the comparable 1999 period. The decrease in operating profit is mostly attributable to the increase in S,G & A discussed above. At the end of the third quarter 1999, the Company sold substantially all of the assets of its computer maintenance and service business, Telos Field Engineering Inc. ("TFE"), to TFE Technology Holdings LLC, an affiliate of Carr & Company, for $10 million. As a result of this sale, The Company recorded a gain of $4.7 million in its consolidated statement of operations for the year ended December 31, 1999. In order to present the statement of operations in accordance with APB 18, the revenues, cost of sales, selling general and administrative and interest expenses for Enterworks, Inc. were presented in one line item "Equity in net losses in Enterworks" due to the deconsolidation of Enterworks on December 30, 1999. (See Note 4 to the consolidated financial statements). The equity in net losses in Enterworks for 1999 was $18.8 million. In 2000, Enterworks continued to recognize losses, accordingly no adjustments to earnings of the Company were made in fiscal 2000 related to the Enterworks investment because the balance of the Company's investment in Enterworks was $0. In order to present the statement of operations in accordance with APB 18, the revenues and cost of sales for the Ft. Sill and DSTATS businesses contributed to TelosOK presented in one line item "Equity in net earnings of TelosOK" due to the joint venture agreement signed July 27, 2000 (See Note 3). The equity in net earnings of Telos OK was $2.3 million for the year ended December 31, 2000. From the effective date of the joint venture agreement through the end of 2000, the Company's share in the equity of TelosOK was negative. Therefore, the Company's investment balance in TelosOK was $0 at December 31, 2000. Interest expense decreased $1.3 million in the year ended December 31, 2000 to $4.8 million compared to $6.1 million in the same 1999 period. This decrease is due to the decreased debt levels in 2000. The income tax provision was approximately $600,000 for the year ended December 31, 2000. The provision incurred was mostly a result of the taxable gain generated from proceeds received from the contribution of assets to TelosOK in July 2000 which was treated as a partial sale of assets for tax purposes (see Note 3). The Company's net deferred tax assets total $7.8 million at December 31, 2000. Failure to achieve forecasted taxable income may affect the ultimate realization of the net deferred tax assets. Management's tax strategy contemplates the generation of taxable income in excess of operating losses sufficient in amounts to realize the net deferred tax assets. The Company recorded an income tax benefit of $7.9 million for the year ended December 31, 1999. The tax benefit was a result of the net operating losses of the Company, partially offset by the gain generated from the sale of TFE. On December 30, 1999 the Company entered into a number of concurrent transactions with its noteholders and its Enterworks subsidiary (See Note 4 of Consolidated Financial Statements). The two most noteworthy of these transactions affecting Telos were as follows: 1. The Company converted approximately $7.6 million of its Senior Subordinated Notes, Series B, C and D held by investors, plus the accrued interest and the waiver of prepayment premium associated with these notes, into shares of Enterworks' Common Stock owned by the Company at an exchange ratio of one share of Enterworks' Common Stock for each $1.00 principal amount of notes payable. These subordinated notes had a maturity date of October 1, 2000. 2. Enterworks purchased 5,000,000 shares of Enterworks' Common Stock owned by the Company at a price of $1.00 per share. This amount was reduced by 20% of the Agent's fee, the Company's pro rata share of the proceeds from the transaction. The net amount received by Telos was $4.7 million. These two transactions resulted in an extraordinary gain, net of tax, of $8.0 million, and were included in the Company's statement of operations for the year ended December 31, 1999. Liquidity and Capital Resources The Company's capital structure consists of a revolving credit facility, subordinated notes, redeemable preferred stock, and common stock. At December 31, 2001, the Company had an outstanding balance of $12.4 million on its $20 million Senior Credit Facility (the "Facility"). The Facility matures on January 15, 2003 and is collateralized by a majority of the Company's assets including inventory, accounts receivable and the Company's stock in its subsidiaries and affiliates. The amount of borrowings fluctuates based on the underlying asset borrowing base. The Facility has various covenants, which may, among other things, restrict the ability of the Company to merge with another entity, sell or transfer certain assets, pay dividends and make other distributions beyond certain limitations. The Facility also requires the Company to meet certain fixed charge coverage and operating goals. At December 31, 2001, the Company was not in compliance with several covenants contained in the Facility, however, the bank has waived such non-compliance. The bank has amended the covenants to conform to the Company's 2002 budget expectations. The Company is in the process of actively negotiating a replacement for the Facility. The Company's subordinated notes are held principally by common shareholders and totaled $8.2 million at December 31, 2001. These notes bear interest at rates between 14% and 17%, with all notes payable on May 23, 2003. The Company currently has two primary classes of redeemable preferred stock - - Senior Redeemable Preferred Stock and Public Preferred Stock. Each class carries cumulative dividend rates of 12% to 14.125%. At December 31, 2001 the total carrying amount of redeemable preferred stock, including accumulated and unpaid dividends was $54.8 million. The Company accrues dividends and provides for accretion related to the redeemable preferred stock. Mandatory redemption for all shares of the Senior Redeemable Preferred Stock plus all accrued dividends on those shares is due May 23, 2003, subject to the legal availability of funds. Mandatory redemption for the Public Preferred Stock is required from 2005 through 2009, subject to the legal availability of funds. Cash provided by operating activities was $13.8 million in 2001, due primarily to improved cash generation from operations, and a decline in the overall accounts receivable balance due to decreases in sales from this year's fourth quarter compared to the prior year's fourth quarter. Cash used in investing activities was $656,000 in 2001, reflecting capital expenditures made by the Company in 2001. The Company used cash for financing activities in the amount of $13.3 million in 2001, reflecting primarily payments made to reduce the balance of the Facility. In July 2000, the Company entered into a subscription agreement with certain investors that provided for the formation of an Oklahoma limited liability company named Telos OK, LLC (See Note 3 to the Consolidated Financial Statements). The Company owns 50% of this joint venture and has guaranteed 50% of the outstanding balance of a term loan TelosOK has with a bank. The balance of this loan was $2.4 million at December 31, 2001.

Capital Expenditures The Company believes that its business is generally not capital intensive. Capital expenditures for property and equipment were $656,000 in 2001, $1.7 million in 2000 and $1.4 million in 1999. The Company anticipates capital expenditures of approximately $1.3 million in 2002; however, there can be no assurance that this level of capital expenditures will occur. Inflation The rate of inflation has been moderate over the past five years and, accordingly, has not had a significant impact on the Company. The Company has generally been able to pass through increased costs to customers through higher prices to the extent permitted by competitive pressures. The Company's cost reduction efforts have generally offset the effects of inflation, if any, on the Company's performance. Recent Accounting Pronouncements The Company currently does not engage or plan to engage in the use of hedging or derivative instruments. Therefore, the implementation of SFAS 133, "Accounting for Derivative Instruments and Hedging Activities" and SFAS 138 "Accounting for Certain Derivative Instruments and Certain Hedging Activities" did not have a material impact on the results of operations, cashflows or financial position. On September 29, 2000, FASB Statement No. 140 ("SFAS 140") "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities", was issued. The new standard replaces FASB Statement No. 125, "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities" and becomes effective for transfers entered into after March 31, 2001. SFAS 140 provides accounting and reporting standards for transfers and servicing of financial assets and extinguishments of liabilities. The implementation of SFAS 140 did not have a material impact on the Company's consolidated financial statements. In June 2001, the Financial Accounting Standards Board ("FASB") approved Statements of Financial Accounting Standards ("SFAS") No. 141, "Business Combinations" and No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 addresses financial accounting and reporting for business combinations. All business combinations in the scope of this Statement shall be accounted for using the purchase method of accounting. The provisions of SFAS No.141 apply to all business combinations initiated after June 30, 2001, and business combinations accounted for by the purchase method for which the date of acquisition is July 1, 2001, or later. Certain transition provisions of SFAS No.141 apply to business combinations for which the acquisition date was before July 1, 2001, that were accounted for using the purchase method, as of the date SFAS No. 141 is initially applied in its entirety. The adoption of SFAS No. 141 did not have a material effect on the Company's financial position, results of operations or cash flows. SFAS No. 142 addresses financial accounting and reporting for acquired goodwill and other intangible assets. Implementation of this Statement will require the Company to cease amortization of goodwill and goodwill will be tested for impairment at least annually at the reporting unit level. Goodwill will be tested for impairment on an interim basis if an event occurs or circumstances change that would "more likely than not" reduce the fair value of a reporting unit below its carrying value. Intangible assets that are subject to amortization will be reviewed for impairment in accordance with SFAS 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of". The provisions of SFAS 142 are required to be applied starting with fiscal years beginning after December 15, 2001 and will therefore be applied for the year ending December 31, 2002. As of January 1, 2002, the Company will no longer amortize goodwill to expense, but will instead review goodwill periodically for impairment. The adoption of SFAS 142 is expected to reduce goodwill amortization expense by $250,000 annually. No material changes to the carrying values of goodwill as a result of the adoption of SFAS 142 are expected to be made. In September 2001, FASB Statement No. 143 (SFAS 143) "Accounting for Asset Retirement Obligations" was issued. SFAS 143 provides guidance on the initial measurement and subsequent accounting for obligations associated with the sale, abandonment, or other type of disposal of long-lived tangible assets. The Company is currently evaluating the provisions of SFAS 143, but does not anticipate the implementation of SFAS 143 to have a material impact on the results of operations, cash flows or financial position. In October 2001, FASB Statement No. 144 (SFAS 144) "Accounting for the Impairment or Disposal of Long-lived Assets" was issued. SFAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets and this statement supercedes FASB Statement No. 121, "Accounting for the Impairment of Long-lived Assets and for Long-lived Assets to be Disposed Of". The Company is currently evaluating the impact and materiality thereof, if any, of SFAS 144 on its financial statements and related disclosures. Forward-Looking Statements This Annual Report on Form 10-K contains forward-looking statements. For this purpose, any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words "believes," "anticipates," "plans," "expects" and similar expressions are intended to identify forward-looking statements. There are a number of important factors that could cause the Company's actual results to differ materially from those indicated by such forward-looking statements. These factors include, without limitation, those set forth below under the caption "Certain Factors That May Affect Future Results." Certain Factors That May Affect Future Results The following important factors, among others, could cause actual results to differ materially from those indicated by forward-looking statements made in this Annual Report on Form 10-K and presented elsewhere by management from time to time. A number of uncertainties exist that could affect the Company's future operating results, including, without limitation, general economic conditions which in the present period of economic downturn may include, and adversely affect, the cost and continued availability of the Company to secure adequate capital and financing to support its business; the impact of adverse economic conditions on the Company's customers and suppliers; the ability to sell assets or to obtain alternative sources of commercially reasonable refinancing for the Company's debt; or the ability to successfully restructure its debt obligations. Additional uncertainties include the Company's ability to convert contract backlog to revenue, the success of the Company's investment in Enterworks and Xacta and the Company's access to ongoing development, product support and viable channel partner relationships with Enterworks and Xacta. While in the past the Company has not experienced contract terminations with the U.S. Government, the U.S. Government can terminate at its convenience. Should such a termination occur, the Company's operating results could be adversely impacted. The increase in the Company's total backlog (referenced above) is primarily attributable to the dual award of the U.S. Army CECOM SEC contract to the Company's 50% owned joint venture, ITel Solutions. The Company will be a subcontractor to this joint venture, and estimates that upon the successful award of each competing task order, its total backlog relating to such contract could be up to $700 million. Conversely, failure to be awarded the majority of the competing task orders for such contract would adversely impact the Company. It should also be noted that post September 11, 2001, all U.S. Government programs, especially those pertaining to national security, have been subject to review and reprioritization. While the Company believes its products and services are well positioned to benefit from such post September 11 demands, the magnitude of such events certainly serves to emphasize how the Company's high percentage of revenue derived from business with the U.S. Government could alternatively be dramatically, swiftly and adversely impacted. In addition, as a high percentage of the Company's revenue is derived from business with the U.S. Government, the Company's operating results could also be adversely impacted should the U.S. Government's annual budget not be approved in a timely fashion. The Company has many patents and patents pending, trademarks and copyrights and other valuable proprietary information, and the Company has taken reasonable and prudent steps to so protect its intellectual property. With regard to the Company's wholly owned subsidiary, Xacta, whose software products require constant monitoring as it develops future releases and creates additional intellectual property, vigilant oversight of such intellectual property rights is imperative. Similarly, the intellectual property associated with our wireless division and our automated message handling system division require constant oversight with regard to the development and protection of their respective intellectual property. Accordingly, any event that brings into question the Company's ownership of its intellectual property could, therefore, materially and adversely impact the Company.

Item 7a. Quantitative and Qualitative Disclosures About Market Risk The Company's exposure to market risk for changes in interest rates relates primarily to the Company's long-term debt obligations. The Company is exposed to interest rate volatility with regard to its variable rate debt obligations under its Senior Credit Facility. This facility bears interest at 1.5%, subject to certain adjustments, over the bank's base rate. This rate will escalate 25 basis points every other month from April 1, 2002 until expiration. The weighted average interest rate in 2001 was 9.13%. This facility expires on January 15, 2003 and has an outstanding balance of $12.4 million at December 31, 2001. The Company's other long-term debt at December 31, 2001 consists of Senior Subordinated Notes B and C which bear interest at fixed rates ranging from 14% to 17%. The Senior Subordinated Notes principal balance at December 31, 2001 is $8.2 million, and this principal amount matures on May 23, 2003. The Company has no cash flow exposure due to rate changes for its Senior Subordinated Notes.

Report of Independent Accountants To the Board of Directors and Stockholders of Telos Corporation: In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of cash flows and of changes in stockholders' investment (deficit) present fairly, in all material respects, the financial position of Telos Corporation and its subsidiaries ("the Company") at December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1. Summary of Significant Accounting Policies Business and Organization Founded in 1968, Telos Corporation ("Telos" or the "Company") delivers enterprise security and integration solutions and services to customers in the U. S. Government and industry. During 2001, America and Telos' largest customer, the U.S. Government, changed forever in terms of their need for an increase in reliable and secure information and communication. Telos solutions address critical needs in the areas of secure wireless networking, secure messaging, secure local area networks ("LAN") data integration and enterprise risk management. Since 1996, Telos has identified and sold a number of business units that were not a part of its strategic direction. These businesses were: Telos Consulting Services, Telos Information Systems, and Telos Field Engineering. In 1999, Enterworks was separately funded and deconsolidated from Telos. Telos now owns 23.1% of Enterworks. In 2000, Telos contributed the net assets of its Ft. Sill operation to a new joint venture with outside investors, resulting in a 50% ownership in TelosOK. These dispositions and ventures, as well as operating cash flows, have enabled Telos to reduce corporate indebtedness from a high of $56.9 million in 1997 to $20.6 million in 2001. During 2001, the Company provided its business solutions through three operating segments: Systems and Support Services Group, the Products Group, and its Xacta subsidiary. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Telos Corporation and its wholly owned subsidiaries, Telos Corporation (California), ubIQuity.com, Inc., Telos International Corporation, Xacta Corporation, Telos.com, inc., and Telos Delaware, Inc. The accounts of the Company's investment in Enterworks, Inc. ("Enterworks") have been deconsolidated as of December 30, 1999, and therefore have been removed from the consolidated balance sheet and statement of changes in stockholders equity. The Company also has a 50% interest in TelosOK, LLC, ("TelosOK") which is accounted for under the equity method of accounting. Significant intercompany transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions used in the preparation of the Company's consolidated financial statements include contract percentage-of-completion methodology, allowance for doubtful accounts receivable, allowance for inventory obsolescence, valuation of goodwill, the valuation allowance for deferred tax assets, employee benefits and estimated useful lives of goodwill, property and equipment and other noncurrent assets, including software development costs. Actual results could differ from those estimates. Revenue Recognition The majority of the Company's sales are made directly or indirectly to the federal government. A substantial portion of the Company's revenues is derived from time and materials contracts, under which revenue is recognized as services are performed and costs are incurred. Revenue from fixed price services contracts is generally recognized over the contract term using the percentage of completion method. The Company generally recognizes product revenue as products are shipped, although certain revenue recognition practices are dependent upon contract terms. Revenue for maintenance contracts is recognized as such services are performed. The Company records loss provisions for its contracts, if required, at the time such losses are identified. The Company adopted the provisions of Staff Accounting Bulletin 101 "Revenue Recognition in Financial Statements" ("SAB 101") during the year ended December 31, 2000. The adoption of SAB 101 did not have a material effect on the Company's results from operations. Revenue from the licensing of software is recognized in accordance with American Institute of Certified Public Accountants (AICPA) Statement of Position ("SOP")97-2 and SOP 98-9, "Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain Transactions". Revenue generated from software subscription contracts is recognized ratably over the subscription period.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company's cash management program utilizes zero balance accounts. Accordingly, all book overdraft balances have been reclassified to accounts payable. Inventories Inventories are stated at the lower of cost or market, where cost is determined primarily on the first-in, first-out method. Substantially all inventories consist of purchased customer off-the-shelf hardware and software, and component computer parts used in connection with system integration services performed by the Company. Inventories also include spare parts of $794,000 and $613,000 at December 31, 2001 and 2000, respectively, which are utilized to support maintenance contracts. Spare parts inventory is amortized on a straight-line basis over five years. An allowance for obsolete, slow-moving or non-salable inventory is provided for all other inventory. This allowance is based on the Company's overall obsolescence experience and its assessment of future inventory requirements. At December 31, 2001 and 2000, the Company's allowance for product inventory was $884,000 and $1,777,000, respectively. The components of the allowance for inventory obsolescence are set forth below (in thousands): Additions Balance, Charge to Balance, Beginning Costs and End of Year Expense Deductions(1) Of Year ------- ------- ------------- ------- Year ended December 31, 2001 $ 1,777 $ 514 $ (1,407) $ 884 Year Ended December 31, 2000 $ 1,992 $ 50 $ (265) $ 1,777 Year Ended December 31, 1999 $ 3,074 $ 600 $ (1,682) $ 1,992 (1) Inventories written off or transferred to fixed assets. Property and Equipment Property and equipment is recorded at cost. Depreciation is provided on the straight-line method at rates based on the estimated useful lives of the individual assets or classes of assets as follows: Buildings 20 Years Machinery and equipment 3-7 Years Office furniture and fixtures 5-7 Years Leasehold improvements Life of Lease Leased property meeting certain criteria is capitalized at the present value of the related minimum lease payments. Amortization of property and equipment under capital leases is computed on the straight-line method over the term of the related lease. Upon sale or retirement of property and equipment, the costs and related accumulated depreciation are eliminated from the accounts, and any gain or loss on such disposition is reflected in the statement of operations. Expenditures for repairs and maintenance are charged to operations as incurred. The Company's policy on internal use software is in accordance with Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use." This standard requires companies to capitalize qualifying computer software costs which are incurred during the application development stage and amortize them over the software's estimated useful life. Depreciation and amortization expense related to property and equipment, including property and equipment under capital leases, was $1,598,000, $1,541,000 and $2,314,000 for the years ended December 31, 2001, 2000 and 1999, respectively.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Goodwill Goodwill arose principally from the acquisition of Telos Corporation (California) in 1992 and has been assigned a useful life of twenty years. The useful life considered a number of factors including the Company's maintenance of long-term significant customer relationships for periods of up to twenty-seven years and its strong positions in the marketplace. The Company assesses the potential impairment and recoverability of goodwill on an annual basis and more frequently if factors dictate. Management forecasts are used to evaluate the recovery of goodwill through determining whether amortization of goodwill can be recovered through projected undiscounted future cash flows. If an impairment of goodwill is indicated, the impairment is measured based on projected discounted cash flows using a discount rate reflecting the Company's cost of funds. In addition, the Company may assess the net carrying amount of goodwill using internal and/or independent valuations of the Company. In June 2001, the Financial Accounting Standards Board ("FASB") approved Statements of Financial Accounting Standard ("SFAS") No. 142, "Goodwill and Other Intangible Assets". SFAS No. 142 addresses financial accounting and reporting for acquired goodwill and other intangible assets. Implementation of this Statement will require the Company to cease amortization of goodwill and goodwill will be tested for impairment at least annually at the reporting unit level. Goodwill will be tested for impairment on an interim basis if an event occurs or circumstances change that would "more likely than not" reduce the fair value of a reporting unit below its carrying value. Intangible assets that are subject to amortization will be reviewed for impairment in accordance with SFAS 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of". The provisions of SFAS 142 are required to be applied starting with fiscal years beginning after December 15, 2001 and will therefore be applied for the year ending December 31, 2002. As of January 1, 2002, the Company will no longer amortize goodwill to expense, but will instead review goodwill periodically for impairment. The adoption of SFAS 142 is expected to reduce goodwill amortization expense by $250,000 annually. No material changes to the carrying values of goodwill as a result of the adoption of SFAS 142 are expected to be made. Accumulated amortization of goodwill at December 31, 2001 and 2000 was $10,006,000 and $9,756,000 respectively. Other Assets Until the deconsolidation of Enterworks on December 30, 1999 (Note 4), other noncurrent assets consisted principally of capitalized software development costs and debt issuance costs. The balance as of December 31, 2001 consists mostly of refundable deposits. There were no unamortized software and product costs at December 31, 2001 and 2000. Amortization expense associated with prior years' capitalized software and product costs was $0, $0 and $1,646,000, in 2001, 2000 and 1999, respectively. Debt issuance costs are amortized over the term of the underlying financial instrument, which amortization method does not differ significantly from the effective interest method. Due to the retirement of $7.6 million of Series B, C and D subordinated notes in December 1999 (Note 7), $72,000 in debt issue costs were written off in 1999. Since 1997, one of the Company's wholly owned subsidiaries, Telos International Corporation ("TIC"), has been a 50% owner of a joint venture between TIC and Filinvest Capital, Inc., a Philippine company. The Company accounted for this joint venture under the equity method of accounting as prescribed by APB No. 18. The investment in this joint venture was included in the other asset balance prior to 2001. In the second quarter of 2001, the Company became uncertain as to whether operations under the joint venture would continue as a going concern. Therefore, the Company determined that its investment in Telos International-Filinvest, Inc. was impaired, and reduced its investment balance in the joint venture to zero. The amount of the write-off totaled $654,000, and is included in the Selling, General and Administrative caption in the statement of operations for the year ended December 31, 2001.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Income Taxes The Company accounts for income taxes under Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes". Under this asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences of temporary differences and income tax credits. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates that are applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized to the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Any change in tax rates on deferred tax assets and liabilities is recognized in net income in the period in which the tax rate change is enacted. The Company provides a valuation allowance that reduces deferred tax assets when it is "more likely than not" that deferred tax assets will not be realized. Accounting for Stock Based Compensation The Company accounts for stock-based compensation using the intrinsic value method provided by Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees." Under APB 25, compensation cost is measured as the excess, if any, of the fair market value of the Company's common stock at the date of grant over the exercise price of the option granted. Compensation cost for stock options, if any, is recognized over the vesting period. The Company has provided additional pro forma disclosures as if the fair value measurement provisions of SFAS No. 123 had been used in determining compensation expense (See Note 9). In April 2000, the FASB issued FASB Interpretation No. 44 "Accounting for Certain Transactions Involving Stock Compensation; Interpretation of APB Opinion No.25" ("FIN 44"). FIN 44 clarifies the application of APB 25 regarding certain key issues. It addresses various interpretive guidelines including: 1) stock compensation granted to non-employees or to employees who have changed their employment status; 2) modifications made to a fixed stock option or award; 3) share repurchase features and tax withholding features; 4) and exchanges due to business combinations. The Company has applied FIN 44 to its stock option plans as of July 1, 2000 and there has been no material impact to the consolidated financial statements from the adoption of this interpretation. Research and Development The Company charges all research and development costs to expense as incurred, until, as in the case of software, technological feasibility is reached after which time such costs are capitalized. During 2001, 2000 and 1999, the Company incurred approximately $925,000, $200,000, and $7.2 million in research and development costs, respectively. Earnings per Share In February 1997, the Financial Accounting Standards Board (FASB) issued SFAS No. 128, "Earnings per Share." This Statement establishes standards for computing and presenting earnings per share (EPS). As the Company does not have publicly held common stock or potential common stock, this Statement is not applicable and, accordingly, no EPS data is reported for any of the years presented. Comprehensive Income Comprehensive income includes changes in equity (net assets) during a period from non-owner sources. The Company has no comprehensive income components other than its net loss. Financial Instruments The Company uses various methods and assumptions to estimate the fair value of its financial instruments. Due to their short-term nature, the carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximates fair value. The fair value of long-term debt is based on the discounted cash flows for similar term borrowings based on market prices for the same or similar issues. The Company has not estimated the fair value of its subordinated debt or its redeemable preferred stock. The Company does not deem such estimation practicable due to the unique features of these instruments. Fair value estimates are made at a specific point in time, based on relevant market information. These estimates are subjective in nature and involve matters of judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Reclassifications Certain reclassifications have been made to the 2000 and 1999 financial statements to conform to the current period presentation.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Recent Accounting Pronouncements The Company currently does not engage or plan to engage in the use of hedging or derivative instruments. Therefore, the implementation of SFAS 133, "Accounting for Derivative Instruments and Hedging Activities" and SFAS 138 "Accounting for Certain Derivative Instruments and Certain Hedging Activities" did not have a material impact on the results of operations, cashflows or financial position. On September 29, 2000, FASB Statement No. 140 ("SFAS 140") "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities", was issued. The new standard replaces FASB Statement No. 125, "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities" and becomes effective for transfers entered into after March 31, 2001. SFAS 140 provides accounting and reporting standards for transfers and servicing of financial assets and extinguishments of liabilities. The implementation of SFAS 140 did not have a material impact on the Company's consolidated financial statements. In June 2001, the Financial Accounting Standards Board ("FASB") approved Statements of Financial Accounting Standards ("SFAS") No. 141, "Business Combinations" and No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 addresses financial accounting and reporting for business combinations. All business combinations in the scope of this Statement shall be accounted for using the purchase method of accounting. The provisions of SFAS No.141 apply to all business combinations initiated after June 30, 2001, and business combinations accounted for by the purchase method for which the date of acquisition is July 1, 2001, or later. Certain transition provisions of SFAS No.141 apply to business combinations for which the acquisition date was before July 1, 2001, that were accounted for using the purchase method, as of the date SFAS No. 141 is initially applied in its entirety. The adoption of SFAS No. 141 did not have a material effect on the Company's financial position, results of operations or cash flows. SFAS No. 142 addresses financial accounting and reporting for acquired goodwill and other intangible assets. Implementation of this Statement will require the Company to cease amortization of goodwill and goodwill will be tested for impairment at least annually at the reporting unit level. Goodwill will be tested for impairment on an interim basis if an event occurs or circumstances change that would "more likely than not" reduce the fair value of a reporting unit below its carrying value. Intangible assets that are subject to amortization will be reviewed for impairment in accordance with SFAS 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of". The provisions of SFAS 142 are required to be applied starting with fiscal years beginning after December 15, 2001 and will therefore be applied for the year ending December 31, 2002. As of January 1, 2002, the Company will no longer amortize goodwill to expense, but will instead review goodwill periodically for impairment. The adoption of SFAS 142 is expected to reduce goodwill amortization expense by $250,000 annually. No material changes to the carrying values of goodwill as a result of the adoption of SFAS 142 are expected to be made. In September 2001, FASB Statement No. 143 (SFAS 143) "Accounting for Asset Retirement Obligations" was issued. SFAS 143 provides guidance on the initial measurement and subsequent accounting for obligations associated with the sale, abandonment, or other type of disposal of long-lived tangible assets. The Company is currently evaluating the provisions of SFAS 143, but does not anticipate the implementation of SFAS 143 to have a material impact on the results of operations, cash flows or financial position. In October 2001, FASB Statement No. 144 (SFAS 144) "Accounting for the Impairment or Disposal of Long-lived Assets" was issued. SFAS 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets and this statement supercedes FASB Statement No. 121, "Accounting for the Impairment of Long-lived Assets and for Long-lived Assets to be Disposed Of". The Company is currently evaluating the impact and materiality thereof, if any, of SFAS 144 on its financial statements and related disclosures. Note 2. Investment in Enterworks During the first quarter of 2001, the Company and Enterworks, Inc. ("Enterworks") entered into an agreement whereby the Company, as a participant in an additional round of financing for Enterworks, substituted approximately $530,000 of receivables owed to the Company and in addition funded Enterworks $470,000 of cash in three equal installments during the quarter. The receivables included rent owed to the Company, services performed by the Company under a service agreement between the Company and Enterworks, and expenses advanced by the Company on behalf of Enterworks for which the Company is reimbursed. In return, the Company received four separate Demand 10% Convertible Promissory Notes from Enterworks totaling $1 million, as well as warrants to purchase 2.5 million of underlying shares of Enterworks common stock. The warrants to purchase 2.5 million underlying shares of Enterworks common stock have an exercise price of $0.01 per share and an exercise period of five years.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS During the second quarter of 2001, the Company and Enterworks entered into an agreement whereby the Company, as a participant in an additional round of financing for Enterworks, committed an additional $800,000 which represented the estimate of amounts owed to the Company for the period May through December 2001 for rent and services performed by the Company under a service agreement. In return, the Company received a $300,000 Demand 10% Convertible Promissory Note from Enterworks, as well as a warrant to purchase 750,000 of underlying shares of Enterworks common stock. The warrants to purchase the shares of Enterworks common stock have an exercise price of $0.01 per share and an exercise period of five years. During the third and fourth quarters of 2001, the Company received five separate Demand 10% Convertible Promissory Notes from Enterworks totaling $500,000, as well as warrants to purchase 1,250,000 of underlying shares of Enterworks common stock. The warrants to purchase the shares of Enterworks common stock have an exercise price of $0.01 per share and an exercise period of five years. During 2001, the Company's ownership interest in Enterworks fell below 20% and accordingly, the Telos designated voting representation on the Enterworks Board was relinquished. However, due to the receipt of the warrants mentioned above, at December 31, 2001 the Company's ownership interest became 23.1%, and therefore the Company now accounts for its investment in Enterworks under the equity method of accounting as prescribed by APB 18. Under this method, and in accordance with EITF 98-13 "Accounting by an Equity Method Investor for Investee Losses when the Investor has Loans to and Investments in Other Securities of the Investee", the Company reduced the carrying amounts of the Notes to $-0- at December 31, 2001, as the Company's share of the Enterworks losses exceeded the carrying value of the Notes. Note 3. Contribution of Assets On July 27, 2000, the Company entered into a subscription agreement with certain investors ("Investors"), which provided for the formation of an Oklahoma Limited Liability Company named Telos OK, LLC ("TelosOK"). The Company contributed all of the assets of its Digital Systems Test and Training Simulators ("DSTATS") business as well as its Government Contract with the Department of the Army at Ft. Sill (hereafter referred to as the Company's Ft. Sill operation) to TelosOK. The net assets contributed by the Company totaled $373,000. The Investors contributed $3.0 million in cash to TelosOK, and at closing TelosOK borrowed $4.0 million cash from a bank. The Company and the Investors have each jointly and severally guaranteed the loan of TelosOK. The Company has guaranteed 50% of the outstanding loan balance and the Investors have guaranteed 25% of the outstanding loan balance. This loan has an outstanding balance of approximately $2.4 million at December 31, 2001. In addition, TelosOK entered into a $500,000 senior credit facility with the same bank, which was subsequently increased to $750,000 on September 30, 2001, with an expiration date of July 1, 2002. Borrowings under the facility, if any, will be collateralized by certain assets of TelosOK (primarily accounts receivable). The Company and the Investors have agreed to guarantee this credit facility in the amount of $250,000 each of the current $750,000 when and if drawn. In compliance with the subscription agreement, on the closing date the following consideration was given to the Company for its contribution of assets to TelosOK: The Company received $6 million in cash, retained $2.5 million in trade receivables of the Ft. Sill and DSTATS businesses, and received a $500,000 receivable from TelosOK for a total consideration of $9 million for the contribution of the net assets.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company and the Investors each own a 50% voting membership interest in TelosOK, and have signed an operating agreement which provides for three subclasses of membership units, Classes A, B and C. The ownership of these classes is as follows and can change upon Class B redemption: Class A - owns 20% of TelosOK. The Company and the Investors each own 50% of the 200,000 units of this class. This class possesses all voting rights of TelosOK and the sole right to elect the directors of TelosOK. The units in this class do not have redemption rights. Class B - owns 40% of TelosOK. The Investors own all 2.9 million units of this class. This class has no voting rights, but can, subject to certain restrictions, request the redemption of all or a portion of the Class B units outstanding one year after the closing date. Class B holders can redeem no more than 500,000 units per quarter at a price of $1.00 per unit, and such redemption can only be made from the excess cash flow of TelosOK as defined in the operating agreement. Class C- owns 40% of TelosOK. The Company owns all 2.9 million units of this class. This class has no voting rights, and has the same redemption rights as Class B, except that no right of redemption will exist until all Class B units have been redeemed. In addition, when any of the Class B units are redeemed, the Company will receive a warrant to purchase Class C units equal to the amount of the Class B units redeemed at a price of $0.01 per unit. As provided for in the operating agreement, one of the Investors, Bill W. Burgess, serves as Chairman of the Board and John R. Braught serves as Secretary, and David Aldrich, President and CEO of the Company, and Thomas Ferrara, Treasurer and CFO of the Company, serves in those same capacities for TelosOK. The Company has entered into a corporate services agreement with TelosOK whereby the Company has contracted to provide certain administrative support functions to TelosOK, including but not limited to finance and accounting and human resources, in consideration for a monthly cash payment.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS As indicated above, the Company owns 50% of TelosOK, sharing control over TelosOK, and accordingly has changed its method of accounting for the contributed assets from the consolidation method to the equity method. Pursuant to this change, the revenues, costs and expenses from the Ft. Sill operation have been excluded from their respective captions in the Company's Consolidated Statement of Operations, and the net earnings from the operation have been reported separately as "Equity in Net Earnings of TelosOK" for the year ended December 31, 2000. The results of operations of the Ft. Sill operation included in the "Equity in Net Earnings of TelosOK" caption are comprised of the following: (in thousands) December 31, 2000 Year ended ------------ Sales $13,339 Cost of Sales (11,011) -------- Gross profit $ 2,328 ======= From July 27, 2000 through December 31, 2001, the Company was unable to recognize its pro rata share of the income generated from TelosOK because the Company's share of TelosOK 's capital accounts was negative. Accordingly, under the equity method of accounting as prescribed by Accounting Principles Board Opinion 18, the Company's carrying value in TelosOK is $0 at December 31, 2001. Note 4. Deconsolidation of Enterworks, Inc. Subsidiary On December 30, 1999, Enterworks, Inc. ("Enterworks"), a majority-owned subsidiary of the Company, completed a private placement of 21,739,127 shares of Series A Convertible Preferred Stock ("Preferred Stock") at a price of $1.15 per share. The sale generated gross proceeds of $25,000,000. In addition, the Company entered into a series of concurrent transactions pursuant to which the Company's voting interest in Enterworks was reduced to approximately 34.8%. The concurrent transactions were as follows: 1. The Company converted approximately $7.6 million of its Senior Subordinated Notes, Series B, C and D held by investors, plus the accrued interest and the waiver of a prepayment premium associated with these notes, into shares of Enterworks' Common Stock currently owned by the Company at an exchange ratio of one share of Enterworks' Common Stock for each $1.00 principal amount of notes payable. These subordinated notes had a maturity date of October 1, 2000. 2. Enterworks purchased 5,000,000 shares of Enterworks' Common Stock owned by the Company at a price of $1.00 per share. This amount was reduced by 20% of the Agent's fee, the Company's pro rata share of the proceeds from the transaction. The net amount received was $4.7 million. This transaction, together with the one described above, resulted in an extraordinary gain, net of tax of $5.3 million, of $8.0 million, which is included in the Company's statement of operations for the year ended December 31, 1999. 3. Enterworks' payable to the Company, which was approximately $24.4 million at December 30, 1999, was cancelled in its entirety before the issuance of Series A Preferred Stock. The forgiveness of the payable increased the Company's investment in Enterworks. Funding required to cover Enterworks' working capital needs from November 30, 1999 to the date of closing was funded by the Company and will be repaid through collections from Enterworks' trade accounts receivable. This funding approximated $2.0 million. This forgiveness of intercompany debt is deemed by management to be a normal occurrence of a capital raising transaction. 4. Enterworks issued 4,000,000 shares of Enterworks' Common Stock to Telos concurrent with the issuance of Series A Preferred Stock. This issuance increased the Company's investment in Enterworks as it increased the number of shares the Company owned in Enterworks. 5. Enterworks issued a warrant to acquire 350,000 shares of Enterworks' Common Stock to Telos' primary lender, Bank of America, in connection with obtaining the necessary approvals for this offering. The exercise price of the warrant equaled $1.15 per share, the same per share price of the Series A Preferred Stock. This warrant was recorded at its fair market value as a charge to interest expense and a reduction to the Company's investment in Enterworks. 6. Telos contributed 210,912 shares of Enterworks' Common Stock owned by Telos to the Enterworks Treasury for the subsequent grant of warrants to the Agent, Deutsche Bank Alex. Brown. This issuance of warrants was also part of the Agent's fee. This contribution of shares was also a charge to interest expense and a reduction to the Company's investment in Enterworks.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS As a result of the reduction of the Company's ownership percentage in Enterworks, in 2000 the Company has changed its method of accounting for its Enterworks subsidiary from the consolidation method to the equity method. Pursuant to this change the revenues, costs and expenses of Enterworks have been excluded from their respective captions in the Company's consolidated statement of operations, and the Company's interest in the losses of Enterworks have been reported separately as "Equity in Net Losses of Enterworks." Additionally, the assets, liabilities, and equity of Enterworks will be excluded from their respective consolidated balance sheet captions and the Company will establish an "Investment in Enterworks" account in accordance with APB 18. The recognition of this net loss by the Company reduced the carrying value of its investment in Enterworks to $0 in 1999. Enterworks continued to recognize losses during fiscal 2000, and in accordance with APB18 the Company has not recognized these losses. The results of operations of Enterworks included in the "Equity in Net Losses in Enterworks" caption for the year ended December 31, 1999 are comprised of the following: Sales $ 11,079 Cost of sales (6,795) Selling, general and administrative expenses (21,695) Interest expense (1,354) -------- Loss before income taxes $(18,765) ======== Enterworks has completed rounds of private financing in 2000 and 2001 which have further diluted the Company's interest in Enterworks. At December 31, 2001, the Company owns 17,153,059 shares of Enterwork's common stock and holds warrants to purchase 4,499,997 underlying common stock shares which equates to a fully diluted ownership percentage of 23.1%. At December 31, 2001, the Company accounts for this investment under the equity method as prescribed by APB Opinon 18. Note 5. Sale of Assets On September 29, 1999, the Company sold substantially all of the assets of its computer maintenance and service business, Telos Field Engineering, Inc. ("TFE"), to TFE Technology Holdings, LLC ("TFE Holdings"), an affiliate of Carr & Company, for $10 million. As a result of this sale, the Company has recorded a gain of $4.7 million in its consolidated statement of operations for the year ended December 31, 1999. This gain included a write-off of $2.1 million of goodwill allocated to TFE operations. The Company and TFE Holdings entered into a one-year corporate services agreement on the date of the sale. Under the terms of the Agreement, Telos provided certain administrative support functions to TFE Holdings, including but not limited to finance and accounting and human resources, in return for a monthly payment. This agreement was terminated in 2000.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 6. Revenue and Accounts Receivable Revenue resulting from contracts and subcontracts with federal, state, and local governments accounted for 97.7%, 96.2%, and 94.1% of consolidated revenue in 2001, 2000 and 1999, respectively. As the Company's primary customer is the federal government, the Company has a concentration of credit risk associated with its accounts receivable. However, the Company does not believe the likelihood of loss arising from such concentration is significant. The Company performs ongoing credit evaluations of its customers and generally does not require collateral from its customers. The Company maintains allowances for potential losses. The components of accounts receivable are as follows (in thousands): December 31, --------------------------- 2001 2000 ---- ---- Billed accounts receivable $20,953 $39,486 ------- ------ Amounts currently billable and other 6,695 8,031 ----- ----- Total unbilled accounts receivable 6,695 8,031 ----- ----- Allowance for doubtful accounts (1,295) (1,835) ------- ------- $26,353 $45,682 ======= ====== The components of the allowance for doubtful accounts are set forth below (in thousands): Balance Additions Charged Beginning to Costs and Balance Of Year Expenses Deductions(1) End of Year ------- -------- ------------ ----------- Year ended December 31, 2001 $1,835 $ 7 $ (547) $1,295 Year ended December 31, 2000 830 1,381 (376) 1,835 Year ended December 31, 1999 739 400 (309) 830 1. Accounts receivable written-off or reserve reversals.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 7. Debt Obligations Senior Revolving Credit Facility At December 31, 2001, the Company has a $20 million Senior Revolving Credit Facility (the "Facility") with a bank which expires on January 15, 2003 and has an outstanding balance of $12.4 million. Borrowings under the facility are collateralized by a majority of the Company's assets including accounts receivable, inventory, and the Company's stock in its subsidiaries and affiliates. The amount of the available borrowings fluctuates based on the underlying asset borrowing base. The facility requires payment of a 0.375% fee of the unused portion of the Facility. The Facility bears interest at 1.5%, subject to certain adjustments, over the bank's base rate, which was 6.5% at December 31, 2001. The interest rate will escalate 25 basis points every other month beginning April 1, 2002 until maturity. The weighted average interest rate on the outstanding borrowings under the Facility was 9.13% for 2001 compared with 10.07% for 2000. The Facility has various covenants which may, among other things, restrict the ability of the Company to merge with another entity, sell or transfer certain assets, pay dividends and make other distributions beyond certain limitations. The Facility also requires the Company to meet certain fixed charge coverage and operating goals. At December 31, 2001, the Company was not in compliance with several covenants contained in the Facility, however, the bank has waived such non-compliance. The bank has amended the covenants to conform to the Company's 2002 budget expectations. The Company is in the process of actively negotiating a replacement for the Facility. The carrying value of the Facility at December 31, 2001 and 2000 approximates fair value. Senior Subordinated Notes In 1995 the Company issued Senior Subordinated Notes ("Notes") to certain shareholders. The Notes are classified as either Series B or Series C. Series B Notes are collateralized by fixed assets of the Company. Series C Notes are unsecured. The notes mature on May 23, 2003, and have interest rates ranging from 14% to 17%. Interest is paid quarterly on January 1, April 1, July 1, and October 1 of each year. The Notes can be prepaid at the Company's option. Additionally, these Notes have a cumulative payment premium of 13.5% per annum payable only upon certain circumstances. These circumstances include an initial public offering of the Company's common stock or a significant refinancing, to the extent that net proceeds from either of the above events are received and are sufficient to pay the premium. Due to the contingent nature of the premium payment, the associated premium expense will only be recorded after the occurrence of a triggering event. At December 31, 2001, the prepayment premium that would be due upon a triggering event is $10.3 million. In April 2001, the Company retired one of its series C subordinated notes with a principal amount of $358,000. In conjunction with the Enterworks private placement offering (See Note 4), the Company retired approximately $1.0 million of Series B Notes, $4.8 million of Series C Notes, and $1.8 million of Series D Notes in exchange for shares of Enterworks' common stock owned by the Company at an exchange ratio of one share of Enterworks' common stock for each $1.00 principal amount of notes payable. In addition to the retirement of these notes, accrued interest of approximately $300,000 was forgiven and the holders of these notes waived their rights to the prepayment premium associated with these notes. The balances of the Series B Notes were $5.5 million at December 31, 2001 and 2000. The balances of the Series C Notes were $2.6 million and $3.0 million, respectively, at December 31, 2001 and 2000. In November 1998, the Company issued additional Senior Subordinated Notes to certain shareholders which were classified as Series D. The Series D Notes totaled $1.8 million and were unsecured. In connection with the debt, the Company issued two warrants to purchase a total of 1,500,000 shares of the Company's Class A Common Stock. As previously discussed, the Warrants had an exercise price of $.01 and an exercise period of 22 months and expired on October 1, 2000. The Series D Notes were retired in conjunction with the Enterworks private placement (Note 4) of 1999.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 8. Redeemable Preferred Stock Senior Redeemable Preferred Stock The components of the senior redeemable preferred stock are Series A-1 and Series A-2, each with $.01 par value and 1,250 and 1,750 shares authorized, issued and outstanding, respectively. The Series A-1 and Series A-2 each carry a cumulative dividend rate of 14.125% per annum of their liquidation value of $1,000 per share. The dividends are payable semi-annually on June 30 and December 31 of each year. The liquidation preference of the preferred stock is the face amount of the Series A-1 and A-2 Stock ($1,000 per share), plus all accrued and unpaid dividends. The Company is required to redeem all shares and accrued dividends outstanding on May 23, 2003, subject to the legal availability of funds. Mandatory redemptions are required from excess cash flows, as defined in the stock agreements. The Series A-1 and A-2 redeemable preferred stock is senior to all other present and future equity of the Company. The Series A-1 is senior to the Series A-2. The Company has not declared dividends on its senior redeemable preferred stock since its issuance. At December 31, 2001 and 2000 undeclared, unpaid dividends relating to Series A-1 and A-2 redeemable preferred stock totaled $3,903,000 and $3,480,000, respectively, and have been accrued and are included in the Series A-1 and A-2 redeemable preferred stock balances. 12% Cumulative Exchangeable Redeemable Preferred Stock A maximum of 6,000,000 shares of 12% Cumulative Exchangeable Mandatorily Redeemable Preferred Stock, par value $.01 per share, has been authorized for issuance. The Company initially issued 2,858,723 shares of 12% Cumulative Exchangeable Mandatorily Redeemable Preferred Stock (the "Public Preferred Stock") pursuant to the acquisition of the Company during fiscal year 1990. The Public Preferred Stock was recorded at fair value on the date of original issue, November 21, 1989, and the Company is making periodic accretions under the interest method of the excess of the redemption value over the recorded value. Accretion for the years ended December 31, 2001 and 2000 was $1,701,000 and $1,555,000, respectively. The Company declared stock dividends totaling 736,863 shares in 1990 and 1991. In November 1998, the Company retired 410,000 shares of the Public Preferred Stock held by certain shareholders. The Public Preferred Stock has a 20-year maturity; however, the Company must redeem, out of funds legally available, 20% of the Public Preferred Stock on the 16th, 17th, 18th and 19th anniversaries of November 21, 1989, leaving 20% to be redeemed at maturity. On any dividend payment date after November 21, 1991, the Company may exchange the Public Preferred Stock, in whole or in part, for 12% Junior Subordinated Debentures that are redeemable upon terms substantially similar to the Public Preferred Stock and subordinated to all indebtedness for borrowed money and like obligations of the Company. The Public Preferred Stock accrues a semi-annual dividend at an annual rate of 12% ($1.20) per share, based on the liquidation preference of $10 per share, and is fully cumulative. Through November 21, 1995, the Company had the option to pay dividends in additional shares of Preferred Stock in lieu of cash. Following November 21, 1995, dividends are only payable in cash. Dividends in additional shares of the Preferred Stock are paid at the rate of 6% of a share of the Preferred Stock for each $.60 of such dividends not paid in cash. Dividends are payable by the Company, provided the Company has legally available funds under Maryland law, when and if declared by the Board of Directors, commencing June 1, 1990, and on each six month anniversary thereof. For the years 1992 through 1994 and for the dividend payable June 1, 1995, the Company has accrued undeclared dividends in additional shares of preferred stock. These accrued dividends are valued at $3,950,000. Had the Company accrued such dividends on a cash basis, the total amount accrued would have been $15,101,000. For the cash dividends payable since December 1, 1995, the Company has accrued $26,323,000. Based upon the Company's interpretation of charter provisions pertaining to restrictions upon payment of dividends, similar dividend payment restrictions contained in its Senior Credit Facility, and limitations pursuant to Maryland law, the Company has not declared or paid dividends on its public preferred stock since 1991.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 9. Stockholders' Investment and Employee Benefit Plans Common Stock The relative rights, preferences, and limitations of the Class A common stock and the Class B common stock are in all respects identical. The holders of the common stock have one vote for each share of common stock held. Subject to the prior rights of the Public Preferred Stock or any series of the Series A redeemable preferred stock, holders of Class A and the Class B common stock are entitled to receive such dividends as may be declared. Stock Warrants In 1994, Toxford Corporation deposited $3 million with the Company's bank to provide the Company with increased borrowing capability under its Facility (see Note 7). In exchange, Toxford Corporation was issued 500,000 shares of Class A common stock for which the Company recorded additional interest expense of $410,000. The Company also granted Toxford Corporation warrants to acquire 7,228,916 shares of the Company's Class A common stock at a purchase price of $.83 per share which approximated the estimated market value of the Company's common stock at the issuance date. In November 1998, 840,000 of these warrants were transferred to certain other shareholders of the Company. The warrant is fully exercisable and has a term of ten years from the date of issue. Stock Options The Company has granted stock options to certain employees of the Company under five plans. The Long-Term Incentive Compensation Plan was adopted in 1990 ("1990 Stock Option Plan") and had option grants under it through 2000. In 1993, stock option plan agreements were reached with certain employees. In 1996, the Board of Directors approved and the shareholders ratified the 1996 Stock Option Plan ("1996 Stock Option Plan"). In 2000, the Board of Directors of the Company approved two new stock option plans, one for Telos Delaware, Inc. and one for Xacta Corporation, both wholly owned subsidiaries of the Company. The Company generally grants options under its respective plans at the estimated fair value at the date of grant. Fair value is determined by the members of the option committee based upon all information available to it. 1990 Stock Option Plan Under the terms of the 1990 Stock Option Plan, 2,168,215 shares of the Company's Class A common stock are available for issuance under options to key employees, including officers and directors. The option price determined by the Board of Directors was not less than the fair market value at the date of the grant and the options are generally exercisable over a four-year period.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1993 Option Plan In 1993, stock option plan agreements were reached to provide Mr. John Wood, Executive Chairman, and Mr. Joseph Beninati, former Chairman, with options to each purchase up to 700,459 shares of the Company's Class A common stock from the Company at $0.50 per share. Under the terms of the agreements, 350,230 shares vested immediately and the remainder vested ratably over the next twelve months. The Company recorded compensation expense related to these options based upon the difference between the exercise price and the estimated fair value of $0.82 per share at the measurement date of the stock option. Mr. Beninati's agreement was canceled in 1996 and the shares now available will be administered under the same terms as the 1996 Stock Option Plan.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Telos Delaware Stock Incentive Plan During the third quarter of 2000, the Board of Directors of the Company approved a new stock option plan for Telos Delaware, Inc., a wholly owned subsidiary of the Company. Certain key executives and employees of the Company are eligible to receive stock options under the plan. Under the plan, the Company may award up to 3,500,000 shares of common stock as either incentive or non-qualified stock options. An incentive option must have an exercise price of not lower than fair market value on the date of grant.

Significant assumptions used in determining the fair value of each option grant at the date of grant were as follows: 1990 Stock 1993 Stock Option Plan Option Plan ----------- ----------- 2001 2000 1999 2001 2000 1999 ---- ---- ---- ---- ---- ---- Expected dividend yield 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% Expected stock price volatility 0.0% 0.0% 0.0% 0.0% 0.0% 0.0% Risk free interest rate -- 5.91% 5.82% -- -- -- Expected life of options -- 2.09yrs 4.0yrs -- -- -- 1996 Stock 2000 Telos Delaware Option Plan Stock Option Plan ----------- ----------------- 2001 2000 1999 2001 2000 1999 ---- ---- ---- ---- ---- ---- Expected dividend yield 0.0% 0.0% 0.0% 0.0% 0.0% -- Expected stock price volatility 0.0% 0.0% 0.0% 0.0% 0.0% -- Risk free interest rate 4.96% 6.59% 5.60% 4.70% 6.01% -- Expected life of options 6.6yrs 4.0yrs 3.6yrs 3.0yrs 3.3yrs -- 2000 Xacta Stock Option Plan ----------- 2001 2000 1999 ---- ---- ---- Expected dividend yield 0.0% 0.0% -- Expected stock price volatility 0.0% 0.0% -- Risk free interest rate 4.70% 6.52% -- Expected life of options 3.0yrs 3.3yrs -- Because the pro forma disclosures under SFAS No. 123 only apply to stock options granted in or after 1995, pro forma net income for 1999, 2000, and 2001 is not necessarily indicative of future periods. Telos Shared Savings Plan The Company sponsors a defined contribution employee savings plan (the "Plan") under which substantially all full-time employees are eligible to participate.

The decrease in the valuation allowance is attributable to forecasted taxable income, which justified the future recognition of the net deferred tax assets recorded. At December 31, 2001, for federal income tax purposes there were no net operating loss carryforwards available to offset future taxable income. The net operating loss carryforwards for both regular and alternative minimum tax purposes were fully utilized in 2000. In addition, the Company has $853,000 of alternative minimum tax credits available to be carried forward indefinitely to reduce future regular tax liabilities. Note 11.
