          MERRIMAC REPORTS FOURTH QUARTER AND FISCAL YEAR 2002 RESULTS


WEST CALDWELL, N.J., APRIL 21, 2003: 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 2002.

Sales for the fourth quarter of 2002 were $5,318,000, a 25.4 percent decrease
compared to fourth quarter 2001 sales of $7,124,000. Operating loss in the
current quarter totaled $1,916,000, or $1,646,000 before giving effect to a
personnel restructuring charge of $270,000, compared to operating income of
$170,000 for the fourth quarter of 2001.

Net loss for the fourth quarter of 2002 was $2,281,000 compared to net income of
$128,000 for the fourth quarter of 2001. Net loss per share was $.73 for the
fourth quarter of 2002 compared to net income per share of $.05 reported for the
fourth quarter of 2001.

For fiscal year 2002, sales were $24,570,000, a 4.7 percent decrease compared to
sales of $25,792,000 for fiscal year 2001. Operating loss for fiscal year 2002
totaled $1,723,000, or $1,213,000 before giving effect to personnel
restructuring charges of $510,000 in the second and fourth quarters, compared to
an operating loss of $113,000 for fiscal year 2001, or an operating income of
$217,000 before the effect of charges associated with the reincorporation in
Delaware of $330,000 in the first quarter of 2001.

Net loss for fiscal year 2002 was $2,135,000, which gives effect to the
after-tax impact of personnel restructuring charges of $510,000 in the second
and fourth quarters of 2002. For fiscal year 2001, net income was $24,000, which
gives effect to the after-tax impact of the first quarter 2001 reincorporation
charge of $198,000.


Net loss per share for fiscal year 2002 was $.69, giving effect to the impact of
the $.17 per share personnel restructuring charges reported in the second and
fourth quarters of 2002. For fiscal year 2001, net income per share was $.01,
giving effect to the after-tax impact of the $.07 per share reincorporation
charge in the first quarter of 2001.

The weighted average number of basic shares outstanding increased by
approximately 478,000 shares or 18.1 percent for the fourth quarter of 2002
compared to the fourth quarter of 2001, and increased by approximately 450,000
shares or 17.1 percent for fiscal year 2002 compared to fiscal year 2001. The
increase in shares outstanding was primarily due to the issuance of 528,000
shares to DuPont Electronic Technologies during the first quarter of 2002.

The backlog at the end of the fourth quarter of 2002 was $10.0 million, a
decrease of $1.8 million or approximately 15.3 percent compared to the backlog
of $11.8 million at year-end 2001. Orders received during the fourth quarter of
2002 totaled $4.4 million and were approximately 19.5 percent below fourth
quarter 2002 sales. Orders received for fiscal year 2002, totaled $22.8 million
and were approximately 7.9 percent below sales recorded in fiscal year 2002. The
reductions in orders and backlog reflected continuing softness in certain
communications markets that the Company serves.

The fourth quarter and fiscal year 2002 operating losses were primarily
attributable to reduced sales resulting from the continuing economic slowdown
especially in the areas served by the Company, and were further impacted because
selling, general and administrative expenses and research and development
expenses did not decrease proportionally in relation to the reduced sales.

The net loss for the fourth quarter and fiscal year 2002 includes establishing a
non-cash valuation allowance of $645,000 (or $.21 per share) against certain
previously recorded deferred tax assets. The Company made an assessment that due
to the uncertainties related to the extent and timing of its future taxable
income, it was appropriate to fully reserve the Company's domestic deferred tax
assets. As a result, the provision for income taxes for the fourth quarter of
2002 was $317,000 and for fiscal year 2002 was $237,000.

On April 17, 2003, the Company's principal loan agreements were amended,
reducing its revolving credit facility from $3,780,000 to $1,000,000, extending
the maturity date of the revolving credit facility from June 30, 2003 to January
31, 2004 and shortening to January 31, 2004 the maturity date on each of its
first mortgage loan from March 2007, and term loan from December 2009. The
Company is treating these loans as a current liability at December 28, 2002.


Management of the Company is contemplating additional cost and capital
expenditure reductions as a means to improve cash flow. Management also believes
that the potential exists for various financing alternatives, including but not
limited to a sale and lease-back of certain property and/or obtaining secured
financing from an asset based lender. While management believes any one of these
financing alternatives, combined with current liquid resources and the expected
cash flows from operations should be sufficient to meet the obligations to Fleet
Bank and currently contemplated operations during the next twelve months, there
can be no assurance that any alternative financings can be obtained by the
Company.

Chairman and CEO Mason N. Carter commented, "The fourth quarter operating
results resulted from a number of factors including some reorganizational
disruption, unfavorable product mix, decreased backlog and an inventory
write-down. The results were particularly disappointing since the first nine
months of 2002 reflected a substantial improvement in operating performance over
2001.

"To limit risk and to offset soft bookings and high level of unpredictability of
order placement and timing, proactive measures were taken by our management team
which included a reduction in force. The total reduction in force during 2002
was 12%.

"While such reductions are never pleasant, and this reorganization was more
difficult to implement than planned, they were clearly required in light of the
current worldwide economic conditions and have allowed us to make positive,
beneficial change."

Mr. Carter continued, "Our new facility is providing high volume, efficient
capability for both conventional technology and Multi-Mix(R). An increase in
commercial Multi-Mix(R) business early in 2003 is directly attributable to the
efficient production capabilities at our new facility. We are also hiring and
training staff for the anticipated conversion of business prospects.

"Successful design wins in the fourth quarter included solutions for the F-15,
F-22 and Joint Strike Fighter, missile radar, satcom, and classified programs.
Included was a complex Multi-Mix(R) integrated module with cross-platform
opportunity."
