Dear Mr. Bailey,

Effective April 16, 2008, Reznick Group, P.C. resigns as the independent registered public accounting firm of Telos Corporation. As a result of certain communications from Class D members of the Board of Directors, Reznick Group believes that its independence has been impaired.

Yours truly,

Alex Castelli

Principal
