                                     PART I

ITEM 1.  BUSINESS

GENERAL

         Merrimac is a leader in passive RF and microwave components for
industry, government and science. Merrimac components are today found in
applications as diverse as satellites, military and commercial aircraft,
cellular radio systems, magnetic resonance medical diagnostic instruments,
personal communications systems ("PCS") and wireless Internet connectivity.

         Merrimac has become a versatile technologically oriented company
specializing in miniature radio frequency lumped-element components, integrated
networks, microstrip and stripline microwave components, subsystems and ferrite
attenuators. Of special significance has been the combination of two or more of
these technologies into single components to achieve superior performance and
reliability while minimizing package size and weight.

         In 1998, Merrimac introduced the Multi-Mix(R) Microtechnology processes
to the marketplace. The Multi-Mix(R) process is an enabling technology that
employs three-dimensional designs of multiple circuit layers bonded together
using a fusion bonding process to help build components and subassemblies at a
fraction of the size, weight and cost of conventional microstrip and stripline
products.

         In February 1999, Merrimac completed the acquisition of all the
outstanding stock of Filtran Microcircuits Inc. ("FMI"), a manufacturer of
microwave micro circuitry. FMI produces technically intricate microstrip, banded
stripline and thick metal-backed Teflon(R) circuits for satellite, aerospace,
telecommunications, automotive adaptive cruise control, navigation and defense
applications worldwide. Merrimac acquired FMI to enable Merrimac to incorporate
FMI's competency in fine line etching into the Multi-Mix(R) Microtechnology
processes and accelerate Merrimac's penetration into the satellite
communications, defense and wireless markets. FMI is operated as a wholly-owned
subsidiary of Merrimac.

         Merrimac was originally incorporated as Merrimac Research and
Development, a New York corporation, in 1954. Merrimac was reincorporated as a
New Jersey corporation in 1994 and subsequently reincorporated as a Delaware
corporation in 2001.



                            DESCRIPTION OF BUSINESSES

RF MICROWAVE AND MULTI-MIX(R) MICROTECHNOLOGY PRODUCT GROUPS

         In 1998, Merrimac introduced Multi-Mix(R) Microtechnology capabilities,
a new innovative process for microwave, multilayer integrated circuits and
micro-multifunction module (MMFM(R)) technology and subsystems. This process is
based on fluoropolymer composite substrates, which are bonded together into a
multilayer structure using a fusion bonding process. The fusion process provides
a homogeneous dielectric medium for superior electrical performance at microwave
frequencies. This 3-dimensional Multi-Mix(R) design consisting of stacked
circuit layers permits the manufacture of




                                       4
<PAGE>



components and subsystems that are a fraction of the size and weight of
conventional microstrip and stripline products.

         In July 2001, Merrimac introduced its Multi-Mix PICO(TM)
Microtechnology. Through Multi-Mix PICO(TM) technology, Merrimac offers a
powerful group of products at a greatly reduced size, weight and cost that
includes hybrid junctions, directional couplers, quadrature hybrids, power
dividers and inline couplers, filters, vector modulators along with 802.11a and
802.11b Wireless LAN (Local Area Network) modules. When compared to conventional
multilayer quadrature hybrids and directional coupler products, Multi-Mix
PICO(TM) is smallest in size, by more than 84% without the loss of power or
performance. Merrimac has completed the development of integrated inline
multi-couplers and are introducing these Multi-Mix PICO(TM) products to major
basestation customers.

         In December 2001, Merrimac received and started to ship, its first 3G
production order for a Multi-Mix PICO(TM) integrated solution to be used by one
of the world's largest suppliers of wireless power amplifiers in the design of
new, 3G broadband basestations.

         In addition to wireless communications, Multi-Mix PICO(TM) products are
currently under evaluation for applications in airborne electronic
countermeasures, radar systems, smart antennas, satellite communications
receiver modules and security equipment.

         In the area of broadband communications, Merrimac is working on
solutions that will bring dual-way Internet access to homes and offices through
a multimedia broadband interactive satellite system.

         Merrimac manufactures and sells approximately 1,500 components and
subsystems used in signal processing systems (the extraction of useable
information from radio signals) in the frequency spectrum of D.C. to 65 GHz.
Merrimac's products are designed to process signals having wide bandwidths and
are of relatively small size and lightweight. When integrated into subsystems,
advantages of lower cost and smaller size are realized due to the reduced number
of connectors, cases and headers. Merrimac's components range in price from $20
to $10,000 and its subsystems range from $500 to more than $100,000.

         Merrimac has traditionally developed and offered for sale products
built to specific customer needs, as well as standard catalog items.
Approximately 30% of 2001 revenues were derived from initial orders for products
custom designed for specific customer applications, 50% from repeat orders for
such products and 20% from catalog sales.

         Merrimac maintains a current electronic catalog on its Internet
website. The Merrimac catalog includes hundreds of standard components, and
provides a selection of passive signal processing components. These components
often form the platform-basis for customization of designs in which the size,
package, finish, electrical parameters, environmental performance, reliability
and other features are tailored for a specific customer application.

         Merrimac's strategy is to be a reliable supplier of high quality,
technically innovative signal processing products. Merrimac coordinates its
marketing, research and development, and manufacturing operations to develop new
products and expand its markets. Merrimac's marketing and development activities
focus on identifying and producing prototypes for new military and commercial
programs and applications in aerospace, navigational systems, telecommunications
and cellular analog and digital wireless telecommunications electronics.
Merrimac's research and development efforts are targeted towards providing
customers with more complex, reliable, and compact products at lower costs.



                                       5
<PAGE>


         The major aerospace companies purchase from Merrimac components and
subsystems that include many complex I&Q networks, quadraphase modulators and
antenna beamformers. Merrimac design engineers work to develop solutions to
customer requirements that are unique or require special performance. Merrimac
is committed to continuously enhancing its leading position in high-performance
electronic signal processing components for communications, defense and
aerospace applications.

         Improved production efficiencies coupled with the capacity of the
low-cost manufacturing facility in Costa Rica and more extensive use of
automated test equipment such as Hewlett Packard network analyzers have resulted
in a considerable reduction of the set-up time to take measurements, calibrate
test equipment and print out hard copy of data. In addition, computerized cost
controls such as closed job history and up-to-date work in process costs are
also enhancing Merrimac's competitive position. Laser marking continues to be
incorporated into the process of metal packages, providing totally permanent
marking, greater flexibility and lower costs.

         Merrimac has also begun to use the Internet to communicate with its
customers more efficiently. Merrimac's On-Line Co-Design(R) system, an
innovative service, allows RF and microwave circuit designers to create and test
their products on-line over the Internet. The customer uses electronic design
automation software together with proprietary circuit elements from the
Multi-Mix(R) library of pre-engineered components and assemblies. This service
allows Merrimac engineers to work more directly with customers as they design
their products.

         For a discussion of financial information about Merrimac's business
segments and geographic data, reference is made to Note 11 of Notes to
Consolidated Financial Statements in Merrimac's Annual Report to Stockholders
for the Fiscal Year Ended December 29, 2001, which note is incorporated herein
by reference.

of prototypes for new programs and applications and the implementation of new
technologies to enhance Merrimac's competitive position. Projects focusing on
surface mounted devices, multilayer, and micro-electronic assemblies are
directed toward development of more circuitry in smaller, lower cost, and more
reliable packaging that is easier for customers to integrate into their
products. Merrimac continues to expand its use of computer aided design and
manufacturing (CAD/CAM) in order to reduce design and manufacturing costs as
well as development time. Current research and development programs at FMI
include: laser machining, resistors on organic materials, high-resolution
circuit techniques, resistor trimming and electroless nickel on aluminum
housings.

ENVIRONMENTAL REGULATION

         Federal, state and local requirements relating to the discharge of
substances into the environment, the disposal of hazardous waste and other
activities affecting the environment have had and will continue to have an
impact on Merrimac's manufacturing operations. Thus far, compliance with current
environmental requirements has been accomplished without material effect on
Merrimac's liquidity and capital resources, competitive position or financial
statements, and management believes that such compliance will not have a
material adverse effect on Merrimac's liquidity and capital resources,
competitive position or financial statements in the future. Management cannot
assess the possible effect of compliance with future requirements.

BACKLOG

         Merrimac manufactures specialized components and subsystems pursuant to
firm orders from customers and standard components for inventory. As of December
29, 2001, Merrimac had a firm backlog of orders of approximately $11,856,000.
Merrimac estimates that approximately 90% of the orders in its backlog as of
December 29, 2001 will be shipped within one year. Merrimac does not consider
its business to be seasonal.

COMPETITION

         Merrimac encounters competition in all aspects of its business.
Merrimac competes both domestically and internationally in the military and
commercial markets and specifically within the




                                       9
<PAGE>

aerospace and telecommunications areas. Merrimac's competitors consist of
entities of all sizes. Occasionally, smaller companies offer lower prices due to
lower overhead expenses, and generally, larger companies have greater financial
and operating resources than Merrimac and well-recognized brand names. Merrimac
competes with all such corporations on a basis of technological performance,
quality, reliability and dependability in meeting shipping schedules as well as
on the basis of price. Merrimac believes that its performance with respect to
the above factors have served well in earning the respect and loyalty of many
customers in the industry. These factors have enabled Merrimac over the years to
successfully maintain a stable customer base and have directly contributed to
Merrimac's ability to attract new customers.

MANUFACTURING, ASSEMBLY AND SOURCE OF SUPPLY

         Manufacturing operations consist principally of design, assembly and
testing of components and subsystems built from purchased electronic materials
and components, fabricated parts, and printed circuits. Manual and
semi-automatic methods are utilized depending principally upon production
volumes. Merrimac has its own machine shop employing CAD/CAM techniques and
etching facilities to handle soft and hard substrate materials. In addition,
Merrimac maintains testing and inspection procedures intended to minimize
production errors and enhance product reliability. Merrimac began manufacturing
in Costa Rica in the second half of 1996. In January 1998, these operations were
moved to a larger facility.

         Effective January 2001, the Company modified its existing lease, and
entered into a resource sharing arrangement with a previous customer, for its
Costa Rica manufacturing facility.

         In February 2001, the Company entered into a new five-year lease in
Costa Rica for approximately 36,200 square-feet for a new Multi-Mix(R)
Microtechnology manufacturing facility. It is anticipated that the leasehold
improvements and capital equipment for this manufacturing facility, which is
expected to cost approximately $4,500,000, should become operational during the
second quarter of 2002.

         FMI's manufacturing facility consists of CAD/CAM, chemical and
mechanical processes, quality systems and R&D of bare circuit board materials
specifically selected for high frequency applications. Manual and automatic
methods are utilized depending upon the circuit volumes, complexity and existing
technologies available to the printed wiring board industry. During the past
year, FMI has added new equipment and procedures to reduce cost and improve
efficiencies in operations. FMI received ISO 9002 certification in April 2001.

         Microwave materials used in FMI's products are available from Rogers
and Arlon. Laminate materials are available from a small number of qualified
suppliers. The suppliers that provide materials to FMI specialize in the
manufacture of microwave materials. Customers often direct FMI to use a
particular vendor for laminates based upon particular design specifications.

         During 1999, Merrimac implemented several programs to improve the
efficiency of its manufacturing operations, reduce costs, foster continual
improvement and improve customer satisfaction. Presently, Merrimac is continuing
to establish and/or refine procedures and supporting documentation to enable the
expedited transfer of product manufacture from prototype engineering to
operational manufacturing. In October 1999, Factory Mutual Research awarded ISO
9001 certification to Merrimac's Multi-Mix(TM) Microtechnology Group
manufacturing facility. In December 2000, they extended this award to the
Company's RF/Microwave Products Group manufacturing facility. In April 2001,
Factory Mutual Research awarded ISO 9002 certification to the Company's FMI
manufacturing




                                       10
<PAGE>

facility in Ottawa, Canada. In October 2001, Factory Mutual recertified the
Company's manufacturing subsidiary located in Costa Rica to ISO 9002. This
location had obtained certification under a different Registrar prior to fiscal
1999.

         Generally, Merrimac uses manufacturing cost savings to enhance its
competitive position.

         Electronic components and raw materials used in Merrimac's products are
generally available from a sufficient number of qualified suppliers. Some
materials are standard items. Subcontractors manufacture certain materials to
Merrimac's specifications. Merrimac is not dependent upon any single supplier
for any of its components or materials.

EMPLOYEE RELATIONS

         As of December 29, 2001, Merrimac employed approximately 240 full time
employees, including 60 employees at FMI and 50 employees at Merrimac's Costa
Rica facilities. None of Merrimac's employees are represented by a labor
organization. Management believes that relations with its employees are
satisfactory.

PATENTS

         As of March 27, 2002, Merrimac owns 8 patents with respect to certain
inventions it developed. No assurance can be given that the protection that
Merrimac has acquired through patents is sufficient to deter others, legally or
otherwise, from developing or marketing competitive products. There can be no
assurance that any of the patents will be found valid, if validity is
challenged. Although Merrimac has from time to time filed patent applications in
connection with the inventions which it believes are patentable, there can be no
assurance that these applications will issue into patents.

ITEM 2.  DESCRIPTION OF PROPERTY

         Merrimac's administrative offices, research and principal production
facilities are located in West Caldwell, New Jersey, on a five-acre parcel owned
by Merrimac. A 12,000 square-foot plant was built in November 1966; a 13,500
square-foot addition was completed in December 1971; and a 26,500 square-foot
addition was completed in July 1980, aggregating 52,000 square-feet presently.
In February 2001, Merrimac began construction of an additional 19,200
square-foot manufacturing facility in West Caldwell, New Jersey, which is
expected to be completed by the end of March 2002.

         Merrimac owns all of its land, buildings, laboratories, production and
office equipment, as well as its furniture and fixtures in West Caldwell, New
Jersey. Merrimac believes that its plant and facilities are well suited for
Merrimac's business and are properly utilized, suitably located and in good
condition.

         Effective January 2001, Merrimac modified its existing lease for a
17,000 square-foot manufacturing facility in Costa Rica by reducing the leased
space to 8,200 square feet and extending the lease for the reduced space through
December 2004. In February 2001, Merrimac also signed a new five-year lease for
a 36,200 square-foot facility in Costa Rica, which will be exclusively devoted
to manufacturing of the Multi-Mix(R) Microtechnology products.

         In February 1999, Merrimac entered into a seven-year lease on a 20,000
square-foot manufacturing facility in Ottawa, Ontario, Canada in connection with
Merrimac's acquisition of FMI.
