John M. Kelley,  President,  stated, "We feel very good about Herley's near-term
and long-term  prospects.  This belief is based, in part, on the strength of the
programs  with  Herley  content  and  the  increasing   level  of  new  business
opportunities.  Our Defense and Aerospace  business  remained  strong during the
second quarter with Defense and Aerospace  revenues  growing 19.6%,  compared to
the same period last year.  A variety of programs  contributed  to this  revenue
growth, including F-16, F-18, AMRAAM and THAAD."

Kelley  continued,  "Second  quarter  bookings hit historic  levels  producing a
book-to-bill  ratio of 1.4 to 1. For the  first  half of fiscal  2004,  Herley's
book-to-bill  radio was 1.2 to 1. Our strong  booking  activity  is  expected to
continue  through  the year.  We are also  continuing  our  efforts  to  acquire
companies that will extend our product line,  assist in Herley's  expansion into
complementary military markets, and secure new positions on desired programs."
