- ----------------------- ------------------- CUSIP No. 126520 20 4 Page 5 of 9 Pages - ----------------------- ------------------- ITEM 4. PURPOSE OF TRANSACTION The purpose of the acquisition of shares of the Issuer's Exchangeable Preferred Stock by VP is for investment. The shares reported on this Schedule were not purchased with the intention of exercising control over the Issuer. Although the Exchangeable Preferred Stock is non-voting stock, it has the exclusive right to vote as a class for up to two directors if at any time or times dividends payable on the Exchangeable Preferred Stock shall be in arrears and unpaid for three consecutive full semi-annual periods. While VP intends to exercise its rights as a stockholder, except as set forth below, none of VP, FEP or Messrs. Fisher and Ewing currently has any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Board; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's Articles of Incorporation, Bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be deleted from a national securities exchange or to cease to be authorized or quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to any of those enumerated above. Notwithstanding the above, VP, FEP or Messrs. Ewing or Fisher may vote the Exchangeable Preferred Stock for up to two directors as permitted by the Issuers's governing corporate documents. In addition, VP, FEP or Messrs. Ewing or Fisher may exercise any or all rights available to holders of the Exchangeable Preferred Stock, including, without limitation, the right to contact other holders of the Exchangeable Preferred Stock, request that a special meeting of holders of the Exchangeable Preferred Stock be called for the purpose of electing two directors to the Issuer's Board of Directors, as permitted by the Issuer's governing corporate documents, or take such other action as it may deem to be appropriate. In the future, VP, FEP or Messrs. Ewing or Fisher may determine to purchase additional shares of the Issuer's Exchangeable Preferred Stock (or other securities of the Issuer) or VP, FEP or Messrs. Ewing or Fisher may determine to sell shares of the Issuer's Exchangeable Preferred Stock. Any such determination will depend on a number of factors, including market prices, the Issuer's prospects and alternative investments. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER a. VP directly and beneficially owns 673,317 shares of the Issuer's Exchangeable Preferred Stock, which represents 18.73% of the Issuer's outstanding shares of Exchangeable Preferred Stock as of August 1, 1995, the date of the share calculation set forth on the Issuer's most recently filed Form 10-Q for the quarter ended June 30, 1995. None of FEP or Messrs. Fisher or Ewing directly owns any shares of Exchangeable Preferred Stock. By reason of the provisions of Rule 13d-3 under the Exchange Act, each of FEP and Messrs. Fisher and Ewing may be deemed

- ----------------------- ------------------- CUSIP No. 126520 20 4 Page 6 of 9 Pages - ----------------------- ------------------- to beneficially own the 673,317 shares of Exchangeable Preferred Stock owned by VP, but disclaim benefical ownership pursuant to Rule 13d-4. b. VP has the sole power to vote and the sole power to dispose of the shares of Exchangeable Preferred Stock owned by it through its general partner, FEP, and FEP acts solely through its general partners, Messrs. Fisher and Ewing. Accordingly, each of FEP and Messrs. Fisher and Ewing may be deemed to have sole voting and dispositive power with respect to the shares of Issuer's Exchangeable Preferred Stock owned by VP. c. Except as disclosed in Exhibit A of this Schedule, none of VP, FEP or Messrs. Fisher or Ewing has effected any transaction in the Issuer's Exchangeable Preferred Stock within the past 60 days. d. No person or entity other than VP has the right to receive, or the power to direct the receipt of, dividends from, or the proceeds from the sale of, the shares of the Issuer's Exchangeable Preferred Stock beneficially owned by VP. e. Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER As of the date of the execution of this Schedule, none of VP, FEP or Messrs. Fisher or Ewing is a party to any contract, arrangement, understanding or relationship among themselves or with any other person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the Exchangeable Preferred Stock, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, the giving or withholding of proxies or pledge or otherwise subject to a contingency the occurrence of which would give another person voting or investment power over the Exchangeable Preferred Stock, other than the agreement among VP, FEP and Messrs. Fisher and Ewing with respect to the filing of this Schedule and any amendments thereto, which agreement is attached as Exhibit B hereto. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS Exhibit A -- Transactions in Exchangeable Preferred Stock During Past 60 Days by VP. Exhibit B -- Agreement among VP, FEP and Messrs. Fisher and Ewing with respect to the filing of Schedule 13D.

- --------------------- ----------------- CUSIP No. 126520 20 4 Page 4 of 6 Pages - --------------------- ----------------- AMENDMENT NO. 1 TO SCHEDULE 13D This statement amends ("Amendment No. 1") the Schedule 13D (the "Schedule") filed by Value Partners, Ltd. and Fisher Ewing Partners with the Securities and Exchange Commission on November 13, 1995, with respect to the 12% Cumulative Exchangeable Redeemable Preferred Stock, $.01 par value per share ("Exchangeable Preferred Stock"), of Telos Corporation, a Maryland corporation (the "Issuer"). All defined terms refer to terms defined herein and in the Schedule. Notwithstanding this Amendment No. 1, the Schedule speaks as of its respective dates. The Schedule is amended only to the extent set forth below: ITEM 4. PURPOSE OF TRANSACTION appearing in the Schedule is deleted in its entirety and replaced with the following: "ITEM 4. PURPOSE OF TRANSACTION The purpose of the acquisition of shares of the Issuer's Exchangeable Preferred Stock by VP and FEP is for investment. The shares reported on this Schedule were not purchased with the intention of exercising control over the Issuer. Although the Exchangeable Preferred Stock is non-voting stock, it has the exclusive right to vote as a class for up to two directors if at any time or times dividends payable on the Exchangeable Preferred Stock shall be in arrears and unpaid for three consecutive full semi-annual periods. The Issuer's Form 10-Q for the quarterly period ended September 30, 1995 stated that no dividends on the Exchangeable Preferred Stock were declared or paid during fiscal years 1994, 1993 and 1992. VP and FEP believe that no dividends on the Exchangeable Preferred Stock were declared or paid during fiscal year 1995. Consequently, VP and FEP believe that, pursuant to the terms of the Exchangeable Preferred Stock, holders of the Exchangeable Preferred Stock currently have the right to elect, voting separately as a class, two directors to the Board of Directors of the Issuer at any annual or special meeting of the stockholders of the Issuer held for the purpose of electing directors. VP currently intends to exercise these voting rights and, in that regard, may: (i) request that the Issuer call a special meeting of stockholders, or include such an election at the next annual meeting of stockholders if the annual meeting will be held within 90 days of the requested special meeting, to elect the two "Class D" directors which may be elected by holders of the Exchangeable Preferred Stock; (ii) request that VP be provided with a list of stockholders of the Exchangeable Preferred Stock and with other corporate documentation of the Issuer; (iii) call a special meeting of Exchangeable Preferred Stockholders to elect the Class D directors if the proper officers of the Issuer fail to do so pursuant to the terms of the Exchangeable Preferred Stock; (iv) nominate one or two persons to run as candidates for the Class D director positions; (v) vote its shares of the Exchangeable Preferred Stock in favor of one or more nominees for the Class D director positions; (vi) take such other action, in its sole discretion, to facilitate the above, including contacting other holders of the Exchangeable Preferred Stock and possibly, the solicitation of proxies in favor of VP's or another stockholder's nominees; or (vii) exercise any or all rights available to holders of the Exchangeable Preferred Stock or take any other action it may deem to be appropriate. In the future, VP, FEP or Messrs. Ewing or Fisher may determine to purchase additional shares of the Issuer's Exchangeable Preferred Stock (or other securities of the Issuer), or VP, FEP or Messrs. Ewing or Fisher may determine to sell shares of the Exchangeable Preferred Stock. Any such determination will depend upon a number of factors, including market prices, the Issuer's prospects and alternative investments.

- --------------------- ------------------ CUSIP No. 126520 20 4 Page 5 of 6 Pages - --------------------- ------------------ While VP and FEP intend to exercise their rights as stockholders, except as set forth above, none of VP, FEP or Messrs. Fisher and Ewing currently has any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Board; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's Articles of Incorporation, Bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be deleted from a national securities exchange or to cease to be authorized or quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to any of those enumerated above."
