                       AMENDMENT NO. 11 to SCHEDULE 13D


     This amendment ("Amendment No. 11") amends the Schedule 13D as previously
filed and amended (the "Schedule") by Value Partners, Ltd. ("VP"), Ewing &
Partners ("E&P") (or its predecessor, Fisher Ewing Partners) and Timothy G.
Ewing with the Securities and Exchange Commission with respect to the 12%
Cumulative Exchangeable Redeemable Preferred Stock, $.01 par value per share
(the "Exchangeable Preferred Stock"), of Telos Corporation, a Maryland
corporation (the "Issuer").  All defined terms refer to terms defined herein
or in the Schedule as previously amended.  This Amendment No. 11 speaks only
as of its date.  Mr. Ewing, E&P, and VP are collectively referred to herein
as the "Reporting Persons."  The Schedule is amended only to the extent set
forth below:

Item 5.  Interest in Securities of the Issuer.

     (a)  According to the Issuer's Report on Form 10-Q for the quarter ended
March 31, 2005, a total of 3,185,586 shares of Exchangeable Preferred Stock
were issued and outstanding as of March 31, 2005.  As of June 2, 2005, VP
beneficially owns 501,317 shares of Exchangeable Preferred Stock, representing
15.7% of the issued and outstanding Exchangeable Preferred Stock.

     (b)  VP has the sole power to vote and dispose of the Exchangeable
Preferred Stock beneficially owned by it.  VP does not share the power to vote
or to direct the vote of, or the power to dispose or to direct the disposition
of, the Exchangeable Preferred Stock owned by it.  E&P, EAM and Mr. Ewing do
not directly own any shares of Exchangeable Preferred Stock of the Issuer.
However, E&P, as a general partner of VP, may be deemed, for purposes of
determining beneficial ownership pursuant to Rule 13d-3, to have the shared
power with VP to vote or direct the vote of, and the shared owner with VP to
dispose of or to direct the disposition of, the Exchangeable Preferred Stock
owned by VP.  Mr. Ewing, as a general partner and the Managing Partner of E&P,
may be deemed, for purposes of determining beneficial ownership pursuant to
Rule 13d-3, to have shared power with VP to vote or to direct the vote of, and
the shared power to dispose or to direct the disposition of, the Exchangeable
Preferred Stock owned by VP.  Although EAM holds a 1% general partner interest
in E&P, EAM does not have any shared voting or dispositive power over the
Exchangeable Preferred Stock owned by VP, as the general partnership agreement
for E&P gives such power solely to Mr. Ewing as the Managing Partner of E&P.

     (c)  On June 2, 2005, VP sold 60,000 shares of Exchangeable Preferred
Stock through a broker at a price of $7.75 per share, net of a broker's
commission.

     (d)  E&P and Mr. Ewing may be deemed to have the power to direct the
receipt of dividends from, or the proceeds from the sale of, the Exchangeable
Preferred Stock owned by VP.

     (e)  Not applicable.
