Directors is in the best interest of Telos Corporation and its stockholders and
recommends a vote "for" the nominees.  The nominees for director, and the 
reasons for Value Partners recommendation, are fully set forth in the proxy 
materials previously mailed to you by Value Partners.

     Regardless of the number of shares you own, it is important that they are
represented and voted at the Special Meeting.  You are encouraged to sign, date
and mail the enclosed duplicate proxy today.  Your interest and participation in
the affairs of the Company is sincerely appreciated.
