TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Note 1. General The accompanying condensed consolidated financial statements of Telos Corporation ("Telos") (formerly C3, Inc.) and its wholly owned subsidiaries, Telos Corporation (California), Telos Field Engineering Inc., and Telos International (collectively, the "Company") have been prepared without audit. Certain information and note disclosures normally included in the financial statements presented in accordance with generally accepted accounting principles have been condensed or omitted. The Company believes the disclosures made are adequate to make the information presented consistent with past practices. However, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual report on Form 10- K for the fiscal year ended December 31, 1994. In the opinion of the Company, the accompanying condensed consolidated financial statements reflect all adjustments and reclassifications (which include only normal recurring adjustments) necessary to present fairly the financial position of the Company as of June 30, 1995 and December 31, 1994, and the results of its operations and its cash flows for the six months ended June 30, 1995 and 1994. Interim results are not necessarily indicative of fiscal year performance because of the impact of seasonal and short-term variations. Included in Systems and Services sales for the six months ended June 30, 1995 are Product sales of $23,563,000. Certain reclassifications have been made to the prior year's financial statements to conform to the classifications used in the current period. Note 2. Accounts Receivable The components of accounts receivable are as follows (in thousands): June 30, 1995 December 31, 1994 Billed accounts receivable $25,832 $32,483 Unbilled accounts receivable 7,858 9,149 33,690 41,632 Allowance for doubtful accounts (836) (1,287) $32,854 $40,345

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Note 3. Debt Obligations Senior Credit Facility On April 17, 1995, the Company refinanced its senior credit facility ("Facility") with its existing lender. The new Facility remains a $45 million commitment with a maturity date of July 1, 1996. Other terms and conditions of the Facility are similar to the Company's previous Facility except that certain financial and non financial covenants have been amended. In 1995, certain of the Company's shareholders have made deposits with the Company's bank to provide the Company with increased borrowing capability under its Facility. Total shareholder deposits with the Company's bank total $7 million. The Company and its shareholders have agreed to negotiate appropriate return to the shareholders for this provision of capital. Such negotiations are in process. The Company currently anticipates that the form of such return will be long term instruments substantially similar to the ones to be issued in exchange for the subordinated bridge notes. See Senior Subordinated Notes, Series B described below. Senior Subordinated Note, Series A At June 30, 1995, the Company had $675,000 of the senior subordinated notes, Series A, outstanding with Mr. John R.C. Porter ("Porter"), the Company's majority common shareholder. The Company was not in compliance with the financial maintenance covenants of the senior subordinated notes, Series A as of June 30, 1995. Porter has agreed to waive such non compliance. Senior Subordinated Notes, Series B The Company entered into an agreement with Union de Banques Suisses (Luxembourg) S. A. ("UBS") on June 8, 1995 whereby the Company paid UBS $5.8 million in outstanding principal, $500,000 of accrued interest and $200,000 of legal and other fees in satisfaction of the claims of UBS with respect to the Series B-1 and B-2 notes. The funds to pay UBS were provided by certain of the Company's common shareholders. The shareholders have been issued subordinated bridge notes aggregating approximately $6.5 million. The notes have a maturity date of October 1, 1996 and have interest rates ranging from 14% to 17 1/2%. Currently, the Company is negotiating terms for certain long term debt instruments that will replace the subordinated bridge notes. While the terms have not been finalized, these debt instruments are expected to bear similar stated interest and may contain certain substantial prepayment premiums currently expected to have a value of approximately 13 1/2% per annum which become due should specified events happen.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Note 4. Preferred Stock Senior Redeemable Preferred Stock The components of the senior redeemable preferred stock are Series A-1 and Series A-2 redeemable preferred stock each with $.01 par value and 1,250 and 1,750 shares authorized, issued and outstanding, respectively. The Series A-1 and A-2 each carry a cumulative per annum dividend rate equal to 9% of their liquidation value of $1,000 per share through June 30, 1995. From July 1, 1995 through June 30, 1997, the dividend rate increases to 11.125% per annum of its liquidation value, and increases again to 14.125% per annum thereafter. 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 Series A-1 and A-2 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. At June 30, 1995 and December 31, 1994 undeclared, unpaid dividends relating to Series A-1. and A-2 Preferred Stock totaled $1,326,000 and $1,192,000, respectively. Class B Redeemable Preferred Stock The Class B Redeemable Preferred Stock has a $.01 par value, with 7,500 shares authorized, issued and outstanding. The Class B Redeemable Preferred Stock has a cumulative dividend calculated at a rate per annum equal to 9% of its liquidation value of $1,000 per share through June 30, 1995. From July 1, 1995 through June 30, 1997, the dividend rate increases to 11.125% per annum of its liquidation value, and increases again to 14.125% per annum thereafter. The Class B Redeemable Preferred Stock may be redeemed at its liquidation value together with all accrued and unpaid dividends at any time at the option of the Company. The liquidation preference of the preferred stock is the face amount, $1,000 per share, plus all accrued and unpaid dividends. The Company is required to redeem all of the outstanding shares of the stock on December 31, 2001, subject to the legal availability of funds. At June 30, 1995 and December 31, 1994 undeclared, unpaid dividends relating to the Class B Redeemable Preferred Stock totaled $2,332,000 and $1,997,000 respectively.

TELOS CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 12% Cumulative Exchangeable Redeemable Preferred Stock A maximum of 6,000,000 shares of 12% Cumulative Exchangeable Redeemable Preferred Stock, par value $.01 per share, have been authorized for issuance. The Company initially issued 2,858,723 shares of 12% Cumulative Exchangeable Redeemable Preferred Stock (the "Preferred Stock"), par value $.01 per share, in connection with the merger. The Preferred Stock accrues a semi-annual dividend at the 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 has the option to pay dividends in additional shares of Preferred Stock in lieu of 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. Dividends in additional shares of the Preferred Stock are paid at the rate of 0.06 of a share of the Preferred Stock for each $.60 of such dividends not paid in cash. No dividends were declared or paid during fiscal years 1994, 1993 and 1992. Cumulative undeclared dividends as of December 31, 1994 are equal to $2,871,000. The Company has accrued these dividends for the periods although the Company is uncertain when or if these dividends will be declared or paid.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. General In the first half of 1995, the Company had comparable revenues to the first half of 1994, and increased operating profit as compared to 1994. The higher operating profit results from declines in selling, general and administrative expenses which include a reduction in rebid efforts and spending on product initiatives. Total backlog from existing contracts was $405 million as of June 30, 1995, as compared to $328 million at December 31, 1994. As of June 30, 1995, the funded backlog of the Company totaled $82 million, a decrease of $11 million from December 31, 1994. Funded backlog represents 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. Results of Operations The condensed consolidated statements of income include the results of operations of Telos Corporation and its wholly owned subsidiaries Telos Corporation (California), Telos Field Engineering Inc., and Telos International ("the Company"). The major elements of the Company's operating expenses as a percentage of sales for the three and six month periods ended June 30, 1995 and 1994 are as follows: Three Months Ended Six Months Ended June 30, June 30, 1995 1994 1995 1994 Sales 100.0% 100.0% 100.0% 100.0% Cost of sales 84.4 80.4 82.6 81.5 SG&A expenses 10.4 14.7 12.5 14.3 Goodwill amortization 1.9 1.9 1.8 1.8 Operating income 3.3 3.0 3.1 2.4 Other income -- -- -- -- Interest expense (3.3) (2.1) (3.0) (1.9) Income tax provision -- -- --- (0.4) Net income --% 0.9% 0.1% 0.1% Financial Data by Market Segment The Company operates in three market segments: systems and services (the "Systems and Services Group"), which consists of systems integration and software services; computer hardware maintenance (the "Field Engineering Group"); and consulting services (the "Consulting Group").

Sales, gross profit, and gross margin by market segment for the periods designated below are as follows: Three Months Ended Six Months Ended June 30, June 30, 1995 1994 1995 1994 (amounts in thousands) Sales: Systems and Services $27,231 $28,612 $58,945 $58,543 Field Engineering 8,055 8,565 16,538 17,269 Consulting 6,516 5,900 13,080 11,314 Total $41,802 $43,077 $88,563 $87,126 Gross Profit: Systems and Services $4,831 $ 5,601 $11,078 $11,046 Field Engineering 685 2,025 1,905 3,435 Consulting 1,022 818 2,426 1,684 Total $6,538 $8,444 $15,409 $16,165 Gross Margin: Systems and Services 17.7% 19.6% 18.8% 18.9% Field Engineering 8.5% 23.6% 11.5% 19.9% Consulting 15.7% 13.9% 18.5% 14.9% Total 15.6% 19.6% 17.4% 18.6% For the three month period ended June 30, 1995, sales declined by $1.3 million, or 3.0%, to $41.8 million from $43.1 million for the comparable 1994 period. The decrease for the three month period is attributable to the Systems and Services Group, which reported a decrease in sales of $1.4 million for the three month period, and to the Field Engineering Group, which reported a decrease in sales of $500,000 for the three month period, offset by an increase in Consulting Group sales for the three month period of $600,000. Within the Systems and Services Group, certain of the Company's software services groups had decreased sales of $900,000 in the three month period due to certain contracts not being renewed during 1995. The decline in sales within the Field Engineering Group of $500,000 in the three month period is attributable to reductions in contract activity for the segment, and in warranty services related to systems integration customers. The Consulting Group sales increase of $600,000 for the three month period is attributable to increased billable hours resulting from obtaining new customers and expanding service to existing customers. Sales increased $1.5 million from $87.1 million to $88.6 million for the six months ended June 30, 1995 as compared to the same 1994 period. The increase for the six month period is attributable to the Systems and Services Group, which had an increase of $400,000 for the six month period, and the Consulting Group, which had a $1.8 million increase for the six month period, offset by a decline in Field Engineering Group sales of $700,000 for the six month period.

For the six month period ended June 30, 1995, the majority of the increase within the Systems and Services Group is due to systems integration sales, which increased $3.7 million in the first six months of 1995 compared to the same period in 1994. This increase is attributable to order volume under the INS contract, which was awarded in September 1994, as well as increased sales in other business lines of the division. The decrease in sales within the Field Engineering Group for the six month period of $700,000 is due to the reductions in contract activity and the performance of warranty services discussed above. The increase of $1.8 million in sales for the Consulting Group for the six month period is the result of the increase in billable hours and expansion of services also discussed above. Cost of sales increased by $700,000 or 1.8%, to $35.3 million in the three month period ended June 30, 1995, from $34.6 million in the comparable 1994 period. The increase in cost of sales is primarily due to the Field Engineering Group, with an increase in cost of sales for the three month period of $800,000. The increase in cost of sales within this Group, despite its decrease in sales for the three month period of $500,000, is attributable to certain increased costs at the division's depots and overseas locations. For the six months ended June 30, 1995, cost of sales increased $2.2 million, or 3.1%, to $73.2 million from $71.0 million for the same period in 1994. The increase is a result of the increase in sales volume for the six month period. Gross profit declined $1.9 million in the three month period to $6.5 million, from $8.4 million in the comparable 1994 period. For the six month period, gross profit decreased by $700,000 to $15.4 million from $16.1 million. The decline in both periods is primarily attributable to the decline in gross profit in the Field Engineering Group discussed above. Gross margins were 15.6% and 17.4% for the three and six month periods of 1995 as compared to 19.6% and 18.6% for the comparable periods of 1994. Selling, general, and administrative expense ("SG&A") decreased by approximately $2.0 million or 31.4%, to $4.3 million in the second quarter of 1995 from $6.3 million in the comparable period of 1994. For the six month period of 1995, SG&A declined $1.3 million to $11.1 million from $12.4 million in 1994. The decreases are primarily due to reduced spending by the Company in certain administrative cost areas and in its bid and proposal and marketing efforts. The Company has also reduced its spending on certain of its product initiatives in 1995. Also, the 1994 period included significant costs associated with contract rebid activities. SG&A as a percentage of sales decreased to 10.4% for the second quarter of 1995 from 14.7% in the comparable 1994 period. SG&A as a percentage of sales for the six month period ended June 30, 1995 decreased to 12.5% from 14.3% compared to the same period in 1994 due to a decrease in SG &A and an increase in sales. Goodwill amortization expense was $795,000 and $1.6 million for each of the three and six month periods, respectively, in 1995 and 1994, as the Company continues to amortize its goodwill balance which resulted primarily from the acquisition of Telos Corporation.

Operating income increased by $100,000 to $1.4 million in the three month period from $1.3 in the comparable 1994 period and increased $600,000 to $2.7 million from $2.1 million for the six month period, as a result of the aforementioned increase in sales and declines in SG&A. Other non-operating income was approximately $4,000 in the three month period of 1995 compared to approximately $14,000 of other non-operating expense in the comparable 1994 period. For the 1995 six month period, non-operating income was $9,000 as compared to income of $14,000 for the comparable 1994 period. Interest expense increased approximately $500,000 to $1.4 million in the second quarter of 1995 period from $900,000 in the comparable 1994 period, as a result of the increase in the outstanding balance of the senior credit facility and related interest rate. Interest expense for the first six months of 1995 of $2.6 million is an increase of $1.0 million from the comparable 1994 period interest expense of $1.6 million. The Company did not have an income tax provision for the three month and six month periods ended June 30, 1995 as a result of utilization of net operating loss carryforwards. For the comparable periods of 1994, the Company had provisions for income taxes of $14,000 and $400,000, respectively. Liquidity and Capital Resources For the six months ended June 30, 1995, the Company used $3.4 million of cash in operating activities. This was primarily the result of the Company's effort to reduce its accounts payable and other liabilities. These uses of cash were funded by the Company's credit facility, which resulted in an increase in the credit facility during the first half of 1995. However, the Company also had significant cash collections of its accounts receivable during the second quarter, which has reduced the credit facility balance from March 31, 1995 to June 30, 1995. Operating cash uses and purchases of property and equipment were funded from borrowings of $4.3 million from the senior credit facility. The Company continues to have constraints on its liquidity as it funds its revenue growth and its product and bid and proposal efforts. The Company has an active cash management program designed to monitor and control significant cash commitments as well as to ensure sufficient funds for Company operations and growth.

At June 30, 1995, the Company had outstanding debt of $45.4 million, consisting of $38.3 million under the secured senior credit facility and $7.1 million in subordinated debt. The senior credit facility was refinanced on April 17, 1995 and has a maturity date of July 1, 1996. Under the terms of the refinancing, the total commitment under the senior credit facility remains at $45 million, with terms and conditions similar to the previous senior credit facility except for amendments made to certain of the financial and non-financial covenants. In 1995, certain of the Company's shareholders have made deposits with the Company's bank to provide the Company with increased borrowing capability under its Facility. Total shareholder deposits with the Company's bank total $7 million. The Company and its shareholders have agreed to negotiate appropriate return to the shareholders for this provision of capital. Such negotiations are in process. The Company currently anticipates that the form of such return will be long term instruments substantially similar to the ones to be issued in exchange for the subordinated bridge notes, described below. At June 30, 1995, the Company had $675,000 of the senior subordinated notes, Series A, outstanding with Mr. John R.C. Porter ("Porter"), the Company's majority common shareholder. The Company was not in compliance with the financial maintenance covenants of the senior subordinated notes, Series A as of June 30, 1995. Porter has agreed to waive such non compliance. The Company entered into an agreement with Union de Banques Suisses (Luxembourg) S. A. ("UBS") on June 8, 1995 whereby the Company paid UBS $5.8 million in outstanding principal, $500,000 of accrued interest and $200,000 of legal and other fees in satisfaction of the claims of UBS with respect to the Series B-1 and B-2 notes. The funds to pay UBS were provided by certain of the Company's common shareholders. The shareholders have been issued subordinated bridge notes aggregating approximately $6.5 million. The notes have a maturity date of October 1, 1996 and have interest rates ranging from 14% to 17 1/2%. Currently, the Company is negotiating terms for certain long term debt instruments that will replace the subordinated bridge notes. While the terms have not been finalized, these debt instruments are expected to bear similar stated interest and may contain certain substantial prepayment premiums currently expected to have a value of approximately 13 1/2% per annum which become due should specified events happen.
