       MERRIMAC REPORTS RECORD FOURTH QUARTER AND FISCAL YEAR 2003 SALES
                     AND PROFITABLE FOURTH QUARTER RESULTS



WEST CALDWELL, N.J., APRIL 1, 2004: Merrimac Industries, Inc. (AMEX: MRM), a
leader in the design and manufacture of RF Microwave components, assemblies and
micro-multifunction modules (MMFM(R)), today announced results for the fourth
quarter and fiscal year 2003.

Sales for the fourth quarter of 2003 were $7,841,000, establishing a quarterly
record for the Company and a 47.4 percent increase compared to fourth quarter
2002 sales of $5,318,000, due to an improvement in orders received earlier in
the year and higher backlog going into the fourth quarter. Fourth quarter 2003
sales included $226,000 from the settlement of rate increases in prior year
contract costs on certain U.S. Government contracts.

Operating income in the fourth quarter totaled $581,000, including $210,000 of
income from such rate increases on prior year contract costs. Operating income
of $581,000 was impacted by a personnel restructuring charge of $31,000 recorded
in the fourth quarter of 2003. Fourth quarter 2003 operating income compares to
an operating loss of $1,916,000 for the fourth quarter of 2002, which included a
personnel restructuring charge of $270,000. Operating results for the fourth
quarter improved as a result of increased sales, improved facilities utilization
and the favorable impact from cost management initiatives instituted earlier in
2003, including a $422,000 or 51.6 percent planned reduction in research and
development costs in the fourth quarter of 2003 compared to the fourth quarter
of 2002.

Net income for the fourth quarter of 2003 was $500,000 compared to a net loss of
$2,281,000 for the fourth quarter of 2002. Net income per share was $.16 for the
fourth quarter of 2003, which included $.07 from rate increases on prior year
contract costs, compared to a net loss per share of $.73 reported for the fourth
quarter of 2002. The net loss for the fourth quarter of 2002 also included a
non-cash valuation allowance of $645,000 ($.21 per share) against certain
previously recorded deferred tax assets, as discussed below.




For fiscal year 2003, sales of $27,322,000 were also a record for the Company.
This represents an 11.2 percent increase compared to sales of $24,570,000 for
fiscal year 2002. Operating loss for fiscal year 2003 totaled $856,000, which
includes aggregate personnel restructuring charges of $160,000 recorded in the
last three quarters, compared to an operating loss of $1,723,000 for fiscal year
2002, which included combined personnel restructuring charges of $510,000 in the
second and fourth quarters of 2002. Expenses associated with bank modification
agreements incurred during the second quarter, additional professional fee
expenses and the accelerated amortization of deferred financing costs in
connection with our prior bank facilities totaled approximately $400,000, and
impacted results for fiscal year 2003. In addition, fiscal 2003 included
$210,000 of income from the settlement of rate increases previously noted and
research and development expenses decreased $992,000 compared to fiscal 2002.

For fiscal year 2003, the net loss was $914,000, which includes the aggregate
impact of personnel restructuring charges of $160,000 recorded during the last
three quarters of 2003, gains on the dispositions of assets of $104,000,
$210,000 of income from increases on prior year contract rates, and $400,000 of
expenses associated with the bank modification agreements. Net loss for fiscal
year 2002 was $2,135,000, which included the impact of combined personnel
restructuring charges of $510,000 in the second and fourth quarters of 2002. The
2002 net loss also included a non-cash valuation allowance of $645,000 against
certain previously recorded deferred tax assets.

For fiscal year 2003, the net loss per share was $.29, which includes the
aggregate impact of $.05 per share personnel restructuring charges taken during
the last three quarters of 2003, gains on the dispositions of assets of $.03 per
share, $.07 of income from increases on prior year contract rates, and $.13 of
expenses associated with the bank modification agreements. Net loss per share
for fiscal year 2002 was $.69, which included the impact of the $.17 per share
combined personnel restructuring charges reported in the second and fourth
quarters of 2002 and the $.21 per share valuation allowance against deferred tax
assets recorded in the fourth quarter of 2002.

The backlog at year-end 2003 was $12.4 million, an increase of $2.4 million or
approximately 23.4 percent compared to the backlog of $10.0 million at year-end
2002. Orders received during the fourth quarter of 2003 totaled $8.1 million and
were approximately 2.7 percent above fourth quarter 2003 sales. Orders received
for fiscal year 2003 totaled $29.7 million, approximately 8.6 percent above
fiscal year 2003 sales.

The decline in gross profit percentage during 2003 to 38.7 percent from 42.6
percent in 2002 was primarily attributable to competitive pricing, additional
production costs above anticipated costs, increases in depreciation and other
occupancy expenses related to expansion and the underutilization of
manufacturing facilities.

Chairman and CEO Mason N. Carter commented, "We clearly benefited from actions
taken in much of 2003 by restructuring and streamlining our operations. These
actions combined with a strong defense segment, along with some pick-up in the
wireless




telecom market, culminated in greatly improved Fourth Quarter sales and
profitable operating results.

Mr. Carter continued, "While one quarter is not a trend, it is a big first step
to significantly improving our operating performance. Our Key Account program,
leading product development and never-ending process improvement programs,
position us well for what we hope will be a strong economic rebound in the
general economy as well as in our focused market segments. Our Key Account
customers are becoming more aware that the tangible value Merrimac supplies is
passed on to our customers and this provides increased value to their
customers."
