                                                                    ------------
                       HERLEY REPORTS 1ST QUARTER RESULTS

                     REVENUES INCREASED 19% to $33.6 MILLION
                         FREE CASH FLOW WAS $5.6 MILLION
                      EARNINGS PER DILUTED SHARE WAS $0.24

Lancaster,  PA. December 9, 2004. Herley Industries,  Inc.  (Nasdaq:HRLY)  today
reported results for the first quarter ended October 31, 2004.  Select financial
results for the first quarter are as follows:

     o  Net sales increased $5.3 million to $33.6 million
     o  Cash provided by operations was $7.7 million
     o  Capital expenditures were $2.0 million
     o  Net income was $3.6 million, 10.6% of revenues
     o  Book to Bill was .96:1 for the first quarter, 1.01:1 for last 12 months

John Kelley,  President said,  "Although our results for the quarter were mixed,
we did make  good  progress,  both  domestically  and at our U.K.  facility,  on
several of the engineering issues that impacted gross margins in the quarter."

Kelley  continued,  "We are  pleased  with the  Company's  free cash flow in the
quarter. Generating healthy cash flow has been an area of emphasis for us and we
expect to continue to see the positive results of our actions in fiscal 2005."

Net sales for the thirteen weeks ended October 31, 2004 were approximately $33.6
million,  as compared to $28.3 million in the thirteen  weeks ended  November 2,
2003, an increase of $5.3 million (19%).  Net sales at two recent  acquisitions,
CTI and RSS, accounted for an increase of approximately $3.5 million,  or 66% of
the  increase for the  quarter.  Herley also  experienced  an  approximate  $3.1
million increase in net sales at its other US operations due to:

     o    The start up of shipments of certain RF power amplifier  products that
          had been in development last year, and

     o    Shipments  of  certain  microwave  frequency   modulation   components
          principally used in electronic warfare simulation systems.

These  increases  in sales in the first  quarter  were  offset by a decrease  in
revenues recognized by EWST,  Herle's UK subsidiary,  due to changes in contract
estimates at that operation  versus  contract  estimates in the first quarter of
fiscal 2004.

The gross profit  margin in the thirteen  weeks ended October 31, 2004 was 32.3%
compared to 37.7% in the first  quarter of fiscal 2004,  a decline of 5.4%.  The
decrease in gross profit is primarily attributable to:

     o    Decreases  of gross  margins  at EWST,  principally  due to changes in
          contract estimates at that operation versus contract  estimates in the
          first quarter of fiscal 2004;

     o    A decline of gross margins at one US operation due to lower  shipments
          and  higher  labor  costs  attributable  to the  start  up of a  major
          electronic  warfare  upgrade  program  for the US  Navy's  EA 6B fleet
          aircraft, offset by

     o    An  improvement  of gross  margins at another US operation  due to the
          increase in volume attributable to start up of shipments of certain RF
          power amplifier products, and shipments of certain microwave frequency
          modulation components referred to above.

Selling and  administrative  expenses for the thirteen  weeks ended  October 31,
2004 were 17.4% of net sales as compared to 16.9% in the first quarter of fiscal
2004.  Almost all of the net increase in expenses of $1 million was attributable
to the addition of selling and  administrative  expenses in connection  with the
acquisitions of CTI and RSS.

Operating  income for the first quarter was $5.0 million or 15% of net sales, as
compared to $5.9 million or 21% of net sales in 2004.  The decrease in operating
income is primarily  attributable to the decline in gross margin percentage (for
the reasons outlined above) and the 0.6% increase in selling and  administrative
costs as a  percentage  of sales,  offset by the  beneficial  impact of the $5.3
million increase in revenue for the quarter.
