HI-SHEAR PRODUCTS

Hi-Shear's products were originally introduced for the United States
space program, and consist primarily of pyrotechnic power cartridges and various
types of aerospace separation devices designed to meet the demand for reliable
high performance devices with the strength to fasten two structures under
rigorous conditions and then provide quick release upon command. In addition,
the Company designs and manufactures electronic systems that sequentially fire
the pyrotechnic devices according to pre-programmed parameters. These electronic
devices are used in missiles, launch vehicles, fighter aircraft ejection seats
and other applications. The Company also adapts its technology to produce
products for other applications where pyrotechnic power is desirable. Hi-Shear's
products can be grouped into four product categories as follows:

POWER CARTRIDGES/INITIATORS. Satellites, missiles, and other space
vehicles require substantial stand-by power to perform certain timing-dependent
functions such as separation, cutting and deployment. Hi-Shear designs, markets
and manufactures pyrotechnic power cartridges/initiators that have a high-energy
output. These power cartridges are hermetically sealed electro-explosive devices
that are compact, lightweight, environment and corrosion resistant and operate
with ultra high reliability. The power cartridge provides the energy to operate
the Company's separation devices, pin pullers, thrusters, actuators and cutters.
These devices are used to open satellite doors, deploy solar panels, booms,
communications antennae, missile fins, and in driving stage separation on many
of today's major launch vehicles. Hi-Shear manufactures the highest reliability
NASA standard initiator used throughout the Space Shuttle.

CARTRIDGE ACTUATED DEVICES. The Company's cartridge actuated devices
are gas-activated products utilized for satellites, missiles and other space
vehicles. These devices include separation nuts, separation bolts, thrusters,
wing/fin actuators, cutters and pin pullers. They are designed for use as
standard high strength fastening hardware with the ability to separate and/or
release components or structures on command. These devices provide the low shock
mechanical action required for rapid separation or deployment of structures or
components in multistage launch vehicles, nose cones and capsules, launching
pads and sleds, ejection seats, booster rockets, tanks, solar arrays, antenna
booms and other devices. The Company maintains an active development program for
new designs, including low shock deployment systems for the increasingly lighter
satellites used in communications and intelligence gathering.

ELECTRONIC PRODUCTS. Hi-Shear is a key supplier both in the U.S. and
overseas of sequencers for the U.S. Air Force ACES II crew ejection seat
installed in many fighter aircraft, including the A-10, B-2, F-15 and F-16. The
Company originally developed the Analog Recovery Sequencer, which electronically
triggers various ordnance events that deploy parachutes and rockets in
connection with the pilot's ejection from fighter aircraft. These safety units
have a service life of seven years after which they must be replaced or
refurbished.

Hi-Shear also supplies electronic safe arm fuzes for tactical and
conventional military programs. The Company's upgraded Patriot (PAC-3) missile
system product is fully developed and has entered the low rate initial
production (LRIP) and full-scale production phases. The Company employs a
proprietary initiator that, when removed, permits full testing of the
electronics without risk to personnel or damaging the integrity of the missile
system. This allows for economical system safety checks, and also a shelf life
estimated at 30 years making it among the longest in the industry.

EMERGENCY CUTTERS. Hi-Shear pyrotechnic emergency cutters are fast,
safe, and reliable rescue tools designed for use in a wide range of emergency
situations for fire and rescue, law enforcement, and military rescue teams. The
LIFESHEAR cutter's light weight, mobility and ease of use enable it to quickly
cut through a variety of tough materials and auto parts in order that a victim
can readily be extracted from a life threatening situation or access can be
quickly gained to a locked area. The LIFESHEAR tool was used by rescue workers
at the site of the World Trade Center disaster in New York City. Hi-Shear's
European licensee is manufacturing and selling the LIFESHEAR product in its
assigned territory.

CUSTOMERS AND CONTRACTS

Most of the Company's customers tend to be large aerospace prime or
subcontractors. Lockheed Martin and the Boeing Company together accounted for
47% of the Company's revenues in fiscal year 2002. The Company's Government
customers include the U.S. Air Force, U.S. Navy, U.S. Army, NASA and other
agencies of the government. Sales to the United States Government as direct
sales represented 11% of revenue in fiscal year 2002. Contract awards and
contract competition phases vary from year to year, and therefore sales
distribution among customers during any one fiscal year should not be considered
indicative of future sales to those customers.
