SELLING SECURITYHOLDERS
The selling holders are offering CODES and shares of common stock issuable
upon conversion of the CODES under this prospectus supplement pursuant to
existing registration rights conferred by the Registration Rights Agreement
dated as of October 24, 2001 among L-3 Holdings, the Guarantors named therein
and Lehman Brothers Inc., Bear, Stearns & Co., Inc. and Credit Suisse First
Boston Corporation, as initial purchasers. The following table sets forth
information, as of January 17, 2002, with respect to the selling holders and
the principal amounts of CODES and number of shares of common stock into which
the CODES are convertible beneficially owned by each selling holder that may be
offered under this prospectus. The information is based on information provided
by or on behalf of the selling holders. The selling holders may offer all, some
or none of the CODES or common stock into which the CODES are convertible.
Because the selling holders may offer all or some portion of the CODES or the
common stock, no estimate can be given as to the amount of the CODES or the
common stock that will be held by the selling holders upon termination of any
sales. In addition, the selling holders identified below may have sold,
transferred or otherwise disposed of all or a portion of their CODES in
transactions exempt from the registration requirements of the Securities Act or
pursuant to our Registration Statement on Form S-3 and amendments or
supplements thereto. Selling holders, including their transferees, pledgees or
donees or their successors, may from time to time offer and sell pursuant to
this prospectus any or all of the CODES and common stock into which the CODES
are convertible. Identification of any additional selling holders, if any, who
exercise their registration rights, pursuant to the registration rights
agreement mentioned above, will be made in the applicable prospectus
supplement.
