Item 1. Business
GENERAL

The Company and its subsidiaries are organized into the following primary
business groups:

Irvine Sensors Corporation
- --------------------------

Irvine Sensors Corporation ("ISC") is the developer of proprietary technologies
to produce extremely compact packages of solid state microcircuitry, which offer
volume, power, weight and operational advantages versus less miniaturized
alternatives.  These advantages result from ISC's ability to assemble
microelectronic chips in a three-dimensional "stack" instead of alongside each
other on a flat surface, as is the case with more conventional methods.  These
stacking technologies have also led to ISC's development of collateral
technologies for the design of low power and low noise chips, thinning of chips
and various specialized applications of chips and stacked chip assemblies in
fields ranging from wireless infrared transmission to image processing to
digital photography.

ISC's core chip-stacking technology was originally conceived and developed as a
means of addressing the demands of space-based surveillance.  However, the
degree of miniaturization realizable from ISC's technologies has attracted R&D
sponsorship from various government funding agencies for a wide variety of
potential military and space applications.  Since its inception, ISC has derived
most of its revenues from such funded research and development.  Since the early
1990s, ISC has sought to commercially exploit its technologies and has received
an increasing share of its consolidated revenues from commercial sales of its
products.

During June 1992, ISC entered into a joint development agreement with IBM to
commercialize ISC's chip-stacking technology for computer memory applications.
In April 1996, ISC purchased a memory-stacking line in Essex Junction, Vermont
from IBM, and in October 1997, disposed of that line and consolidated that
sector of its business with its California operation.  In October 1995, ISC
formed a subsidiary, Novalog, Inc. ("Novalog"), to commercially exploit its low
power chip technology in the field of wireless infrared data communications.  In
April 1997, ISC formed a subsidiary, MicroSensors, Inc. ("MSI"), to commercially
exploit its technologies for low noise readout electronics and miniaturized
inertial sensors.  In June 1998, ISC formed a subsidiary, Imagek, Inc.
("Imagek") to commercially exploit its digital photography technologies.

Novalog, Inc.
- -------------

Novalog is a privately financed subsidiary of ISC which designs, develops and
sells proprietary integrated circuits ("ICs") for use in wireless infrared
communication. Novalog's initial products, trademarked SIRComm(TM), SIR2(TM),
MiniSIR(TM), MiniSIR2(TM) and BayBeamer(TM), enable infrared, line-of-sight data
transfer between computers, electronic organizers, printers, modems and other
electronic devices that have compatible ports. Novalog is an active participant
in the Infrared Data Association ("IrDA"), which establishes the hardware and
software protocols for such products. Novalog believes its products have
advantages in terms of power consumption, dynamic range, size and economics as
compared to the products of its competitors. Novalog has shipped more than five
million units of its products to manufacturers servicing the IrDA marketplace.
In fiscal 1998, Novalog accounted for approximately 11% of the Company's
consolidated revenues.
<PAGE>
 
MicroSensors, Inc.
- ------------------

MSI is a wholly-owned subsidiary of ISC that was formed to develop and sell
proprietary micromachined sensors and related electronics. Micromachining
involves the use of semiconductor manufacturing processes to build
electromechanical devices with feature sizes measured in microns or fractions
thereof. As prices have declined for micromachined devices, such solid-state
units have migrated from initial aerospace and military applications to
automotive, industrial process-control and medical applications. SRI Consulting
(Menlo Park, CA) has reported that some observers expect sensors built in this
manner to eventually replace virtually all electromechanical sensors, creating a
market of several billion dollars annually. MSI has supported a U.S. government
contract conducted by ISC for development of a proprietary microgyro with
projected performance features heretofore achievable only at much higher cost.
Subsequent to the completion of this contract, MSI has demonstrated functional
units of the MicroRing Gyro. Effective October 1997, MSI negotiated its first
commercial contract and has commenced development and shipment of engineering
samples of a multi-channel readout chip pursuant to that contract. Production
shipments pursuant to this contract are scheduled to begin in fiscal 1999. MSI
accounted for approximately 3% of the Company's consolidated revenues in fiscal
1998.

Imagek, Inc.
- ------------

Imagek Inc. is a subsidiary of ISC which designs, develops and intends to sell
proprietary electronic film systems and other digital imaging products and
services. Although dependent on completion of required financing, the success of
which cannot be assured, Imagek is planning to introduce in fiscal 1999 the EFS-
1(TM) Electronic Film System that includes a self contained, compact, battery-
powered cartridge that fits into the film cavity of a 35mm camera thus offering
the flexibility to switch between conventional film and digital photography.
Other collateral products and services are planned for introduction subsequent
to the EFS-1(TM).

ISC was incorporated in Delaware in January 1988. Pursuant to a merger effective
in May 1988 with a corporation of the same name incorporated in California in
December 1974, the Company succeeded to all of the assets and liabilities of
such predecessor corporation.  Its principal executive offices are located at
3001 Redhill Avenue, Building. 3, Costa Mesa, California 92626, and its
telephone number is (714) 549-8211.

Novalog was incorporated in California in October 1995.  Its principal executive
offices are located at 125 Kalmus Drive, #K-1, Costa Mesa, California 92626, and
its telephone number is (714) 429-1122.  Novalog is a consolidated subsidiary of
ISC.

MSI was incorporated in Delaware in April 1997.  Its principal executive offices
are located at 3001 Redhill Avenue, Building 3, Costa Mesa, California 92626,
and its telephone number is (714) 444-8831.  MSI is a consolidated subsidiary of
ISC.

Imagek was incorporated in Delaware in June 1998. Its principal executive
offices are located at 3001 Redhill Avenue, Building 3, Costa Mesa, California
92626, and its telephone number is (714) 444-8723. Imagek is a  consolidated
subsidiary  of ISC.

Products and Technology
- -----------------------

The Company has developed a variety of products consisting of stacked memory
chips, and believes that its chip stacking technology can offer demonstrable
benefits to designers of systems that incorporate numerous integrated circuits,
by improving speed and reducing size, weight and power usage.  In addition,
since ISC's technology reduces the number of interconnections between chips,
potential system failure points can also decrease.

The Company believes that the features achievable with its chip stacking
technology will have application in space and in aircraft in which weight and
volume considerations are dominant, as well as in various other applications in
which portability is required and speed is important.  The Company is presently
seeking to exploit its potential market by focusing on the sale of chip stacking
products to high end, high margin government and commercial users to whom the
technical improvement will be most valuable.  While these applications tend to
require lower unit volume, the sales are at significantly higher prices than
many 

<PAGE>
 
applications requiring high volume production.  Furthermore, the Company
has existing relationships with some of the potential customers in this market.

Since fiscal 1995, the Company has been shipping quantities of its stacked
memory products to customers for both government and commercial purposes.
However, there is no assurance that the Company will be successful in marketing
such products for widespread applications.  The Company also intends to continue
to market infrared sensing devices for surveillance, acquisition, tracking and
interception applications for a variety of Department of Defense ("DOD") and
NASA missions.

The Company is not aware of any technical disadvantages to its chip stacking
technology. However, until high volume production is achieved, as to which
there is no assurance, the ultimate cost of products utilizing the Company's
higher density chip stacking technology cannot be firmly established,
potentially placing the Company's stacked chip products at a cost disadvantage.
Accordingly, in fiscal 1998, the Company expanded its product offerings to
include lower-density stacked electronics that the Company believes could be
more price competitive.

In addition to its chip stacking technology, the Company has developed a Serial
Infrared Communications chip using elements of its sensor chip design
technology.  This device is being used in products which allows computers and
computer peripherals to communicate using infrared transmissions in a manner
similar to that employed by remote control units for televisions and video
cassette recorders.  Novalog has been shipping such devices since 1995.

The Company also has chip design technology relating to electronic readouts that
it is exploiting through its MSI subsidiary.  In fiscal 1998, MSI entered into
its first contractual relationship based on this technology, i.e., a contract to
develop and subsequently ship production quantities of its readout chip for EG&G
Astrophysics, Inc. ("EG&G") to be utilized in airport security systems.  MSI
successfully completed the development phase of EG&G's contract in fiscal 1998,
and will commence production shipments under the contract in fiscal 1999.  MSI
has also developed a proprietary Silicon MicroRing Gyro intended to provide an
inexpensive means to measure angular motion for a wide variety of potential
applications.  The Silicon MicroRing Gyro is presently being packaged for
evaluation by potential customers. Commercial exploitation of this product is
expected to be paced by the product design-in lead times required by such
customers.  As a result, the Company does not project material contributions to
its consolidated revenues from this product during fiscal 1999.

In June 1998, the Company formed its Imagek subsidiary to commercially explore
its proprietary technologies, focused on miniaturized digital cameras. Imagek is
presently developing the production version of its initial product, the 
EFS-1(TM), which is an electronic film system including a cartridge that can be
inserted into an existing film camera allowing that camera to take digital
pictures without modification to the camera itself. Imagek is seeking private
financing to introduce this product and support its business plan. Imagek
believes that its proprietary EFS technology has value advantages to potential
customers with substantial investment in conventional 35MM camera equipment that
inhibits the adoption by those consumers of self-contained digital cameras. By
utilizing the optics of existing cameras, Imagek believes that the EFS product
will be economically competitive to comparable resolution digital cameras.

Potential Product Applications
- ------------------------------

Neural Networks.  In 1991, the Company received initial funding from the U.S.
Navy's Office of Naval Research for potential use of its technology in neural
networks.  After the completion of this exploratory phase, the Company received
various add-on and collateral contracts aggregating over $9 million, through
fiscal 1998, to further develop the neural network technology.  The Company is
presently pursuing additional contracts, under which the Company expects to
deliver demonstration products to various branches of the DOD.  Neural networks
contain large numbers of sensing nodes which continuously interact with each
other, similar to the way that the neurons of a human brain interact to process
sensory stimuli.  Neural networks are the subject of scientific inquiry because
pattern recognition and learning tasks, which humans perform well and computers
perform poorly, appear to be dependent on such processing.  Neither conventional
computers nor advanced parallel processors currently have the interconnectivity
needed to fully emulate neural network processing techniques.  The Company
believes its chip stacking technology could offer a way to achieve the very high
levels of interconnectivity necessary to construct an efficient artificial
neural network.  To the Company's knowledge, no other presently available
packaging approaches are believed to offer this potential.  
<PAGE>
 
The full embodiment of this technology is not expected to yield near-term
products for the Company, although it is anticipated to keep the Company
actively involved in advanced R&D relevant to the Company's long-range business
interests. However, elements of this technology, including a proprietary chip
set, are currently being developed with a view to product utilization, although
there can be no assurances as to the potential success of such development.

Wearable Computers.  In fiscal 1998, the Company commenced exploration of a
technology to stack chips of different functionality and dimensions within the
same chip stack.  The Company refers to this new technology as NeoStack. The
Company is using its NeoStack technology to support a government program
undertaken by the Boeing Corporation ("Boeing"), to develop a wearable computer.
The Company believes that its NeoStack approach could offer advantages in terms
of compactness and power consumption to developers of wearable computer systems.
However, because of remaining developmental requirements, the Company is
presently unable to forecast when or if such technology will be incorporated in
commercial products and, because of product design lead times, does not
anticipate such incorporation during fiscal 1999.


Development Contracts
- ---------------------

In April 1980, the Company entered into an agreement with R & D Leasing Ltd.,
("RDL"), a limited partnership in which the Company's Chairman of the Board and
a Senior Vice-President are general partners with beneficial interests, to
develop certain processes and technology related to chip stacking.  The Company
has exclusively licensed this technology from RDL. The Company's exclusive
rights to the technology extend to all uses, both government and commercial.
Since entering into the licensing agreement, the Company has accrued royalty
obligations to RDL at the rate of 3.5% of all Company sales of chip stacks using
the licensed technology.  In addition, RDL is entitled to receive an amount
equal to 7% of all royalties earned by the Company from sales of any such
products by the Company's sublicensees, although to date, no such sublicensee
royalty income has been earned.

In October 1989, RDL agreed to defer its royalty claims and subordinate them
with respect to all other creditors in exchange for options to purchase up to
1,000,000 shares of the Company's Common Stock, which are exercisable by
applying the deferred royalties to the purchase.  The 1,000,000 options are
exercisable at $1.00 until October 1999.  If RDL exercises its option in whole
or in part, title to RDL's technology would transfer to the Company and all
further royalty obligations would cease.  If the option expires unexercised, the
subordination provisions would terminate and the accrued royalties would be due
and payable in the same manner as any other corporate obligation.

As of September 27, 1998, the Company had accrued $826,200 in deferred royalties
pursuant to this agreement.  Due to the RDL subordination, royalties accrued,
but none were paid by the Company during fiscal years 1998, 1997 and 1996. 

Manufacturing
- -------------

At the present time, the Company stacks DRAM, SRAM and FLASH memory die
purchased from commercial sources into cube-shaped assemblies at its own
facility. The cubes are then either packaged or segmented into subsections as
required for the particular product configuration being built.  Outside vendor
support is utilized for packaging.  During fiscal 1998, the Company introduced
products involving the stacking of pre-packaged die using widely-available
fabrication technologies. The Company uses outside third party qualified source
vendors for the manufacturing of these products.

The primary components of the Company's non-memory products are integrated
circuits and infrared detectors.  The integrated circuits are designed by the
Company for manufacture by others from silicon wafers and other materials
readily available from multiple sources.  Due to the ready availability of these
materials, the Company does not have any special arrangements with suppliers for
their purchase.  The Company does not produce detectors.  However, the Company
has developed a process which enables it to use relatively low cost and
unsophisticated detectors which are generally available from numerous sources.
<PAGE>
 
Because of the nature of the sophisticated research and development work
performed under its development contracts, the Company designs and assembles
equipment for testing and prototype development.  The Company utilizes the
unique capability of this equipment to seek, qualify for and perform additional
contract research and development for its customers.

Backlog
- -------
At December 13, 1998, the Company's funded backlog was $3,468,600 compared to
$2,263,200 at December 14, 1997.  The Company anticipates that all of the funded
backlog will be filled in fiscal 1999.  In addition, the Company has substantial
unfunded backlog on contracts which typically are funded when the previously
funded amounts have been expended.  The Company is also continuing to negotiate
for additional research contracts and commercial product sales, which, if
obtained, could materially increase its backlog.  Failure to obtain these
contracts in a timely manner could materially affect the Company's short-term
results.

Customers and Marketing
- -----------------------

The Company's Advanced Technology Division ("ATD") focuses its product marketing
efforts on U.S. military agencies or contractors to those agencies.   The
Company is continually seeking and preparing proposals for additional contracts.
As a result of the post cold war defense cutbacks, many defense contractors have
experienced declines in their business base as government agencies' budgets are
reduced.  However, even if this trend continues, the Company believes there will
be more emphasis and funds directed toward advanced technology systems and
research programs for which the Company believes it is qualified to compete.
However, there can be no assurances that the Company will be successful in
competing against the larger defense contractors for potential programs.

The Company's Novalog subsidiary supports Original Equipment Manufacturers
("OEM's") supplying infrared communications devices complying with the standards
of the Infrared Data Association ("IrDA"). Novalog's active participation in
IrDA facilitates its marketing to those customers.

MSI directs its marketing toward three commercial areas: (i) Customers with a
need for Application Specific Integrated Circuits ("ASICs") such as the type
developed for EG&G; (ii) OEMs that have a need for the cost and performance
features that could be provided by MSI's Silicon MicroRing Gyro, with particular
emphasis toward manufacturers of electronic toys and games, industrial
monitoring equipment, medical instrumentation and automotive markets; and  (iii)
the manufacturers of micromachined sensors who may be able to utilize MSI's
Universal Capacitive Readout(TM) ("UNICAP(TM)") general purpose ASIC designed to
support  a  variety of sensors  requiring high accuracy capacitive readout and
control electronics.

Imagek is a consumer product focused enterprise.  Both the structure and
staffing of Imagek was developed to bring digital imaging products to the
consumer market.  The initial product of Imagek, the Electronic Film System
("EFS")  is designed to enable 35mm camera owners to shoot digital or
traditional photography with equipment they currently own.  The initial target
market, termed "prosumers", are defined as high end hobbyists and business
photographers who have made a significant investment in their camera systems.
The EFS is being positioned as a camera accessory, leveraging off the growing
adoption of digital cameras and related infrastructure.

Imagek is planning a limited roll out of the initial EFS-1(TM) product, largely
through direct follow-up of inquiries from potential customers it has received,
and expects to follow with an expansion of distribution, reseller channels and
value-added resellers for broad and vertical markets.  Imagek plans to service
its customers with a sophisticated electronic commerce site, an 800 access
number, and a customer web site information vehicle.

In fiscal 1998, contracts with all branches of the U.S. government accounted for
54% of the Company's consolidated revenues, the remaining 46% of the Company's
revenues was derived from non-government sources.  During fiscal 1998, revenues
derived from the U.S. Army and the various divisions of the Boeing Corporation
accounted for approximately 13% and 14% of total consolidated revenues,
respectively.  Loss of these customers would have a material adverse impact on
the Company's results.
<PAGE>
 
Contracts with government agencies may be suspended or terminated by the
government at any time, subject to certain conditions.  Similar termination
provisions are typically included in agreements with prime contractors.  From
time to time, the Company has experienced such suspensions or terminations, and
there is no assurance the Company will not experience such suspensions or
terminations in the future.

The Company focuses its marketing in specific areas of interest in order to best
utilize its relatively limited marketing resources.  Each operating unit or
subsidiary has a designated individual to direct that unit's marketing efforts.
The Company is presently recruiting for a senior management executive to
coordinate these activities corporate-wide.

Competition
- -----------

The demand for high performance semiconductors has produced a wide variety of
competitors and competitive systems, ranging from various three-dimensional
designs to highly dense two-dimensional designs.  For most commercial
applications, the principal competitive factor for such products is the cost
premium over less densely packaged electronics.  For some application in which
volume and weight are critical, such as space or avionics, density becomes the
principal competitive factor.  Many of the Company's competitors are believed to
be better financed, more experienced and organizationally stronger than the
Company.  Accordingly, there can be no assurances that the Company can
successfully compete in such markets.

The Company is aware of two large companies that have developed competing
approaches to chip stacking.  They are Texas Instruments, Inc. (TI) and Thompson
CSF (Thompson).  In addition, there are several small companies and divisions of
large companies that have various technologies for stacking a limited number of
chips.

The Company is aware of many companies which are currently servicing the
military market for electro-optical sensors of the type which the Company's
products are also designed to support.  The principal competitive factor in this
business area is the performance sensitivity and selectivity achievable by
alternative sensor approaches and designs.  Competitors to the Company include
Santa Barbara Research Center, TI, Lockheed Martin Corporation, Raytheon, Litton
Industries, Infrared Industries, Inc., EG&G Judson, OptoElectronics-Textron,
Inc., and Boeing Corporation.  The Company believes that most of its competitors
in this area have financial, labor and capital resources greater than those of
the Company and there is no assurance that the Company will be able to compete
successfully.

The Company is aware of several companies which currently service the market for
serial infrared detectors of the type sold by Novalog.  For battery-powered
applications, the principal competitive factors are power consumption and cost.
For desktop applications, the principal competitive factor is the speed of data
transmission achievable.  Novalog believes that it has competitive advantages in
the battery-powered applications.  Competitors to Novalog include Hewlett-
Packard, Temic, Sharp, and IBM, among others, all of whom have financial, labor
and capital resources greater than those of Novalog.

MSI is competing in a market populated with several larger competitors as
relates to its Silicon MicroRing Gyro, including such companies as Delco
Electronics, Motorola, Bosch Corporation, Siemens and Systron-Donner.  The
principal competitive factor for these applications is believed to be cost.  MSI
has no present knowledge of competitors planning to introduce ASICs competitive
to its planned UNICAP product, but given the widespread availability of
integrated circuit design capabilities in the electronics industry, the
emergence of competitive products is believed to be likely.

Imagek is not aware of any direct competitors to its contemplated EFS product
line and believes that its intellectual property will act as a barrier to
competitors seeking to offer identical products, although there can be no
assurances of that result.  However, the EFS system itself is expected to face
competition from increasingly sophisticated generations of digital camera
equipment.  Peripheral equipment and services which Imagek intends to offer to
complement its EFS products are also likely to attract strong competition if the
EFS product line receives significant market acceptance.

Research  and Development
- -------------------------

The Company believes government and commercial research contracts will provide
the major portion of funding necessary for continuing development of some of its
products.  However, the manufacture of stacked 
<PAGE>
 
circuitry modules in volume will require substantial additional funds, which may
involve additional equity or debt financing or a joint venture, license or other
arrangement. Furthermore, the development of the products of its subsidiaries
are likely to require such external funding. There can be no assurance that
sufficient funding will be available from government or other sources or that
new products of the Company or its subsidiaries will be successfully developed
for volume production.

The Company's consolidated expenditures for research and development for the
fiscal years ended September 27, 1998, September 28, 1997, and September 29,
1996 were $1,609,500, $1,616,600 and $2,009,700, respectively.  These
expenditures of Company funds were in addition to the Company's cost of revenues
associated with its customer-sponsored research and development activities.  The
spending levels of Company funds on research and development compared to its
overall expenses are indicative of the Company's resolve to maintain its
competitive advantage by developing new products and improving upon its existing
technology.

The Company has funded its research and development activities primarily through
contracts with the federal government and with funds from the Company's public
and private stock and bond offerings.

Patents, Trademarks and Licenses
- --------------------------------

The Company has a policy of protecting its investment in technology by seeking
to obtain, where practical, patents on the inventions made by its employees.  As
of September 27, 1998, 50 U.S. and foreign patents have been issued and assigned
to the Company or its subsidiaries and other U.S. and foreign patent
applications are pending. There is no assurance that additional patents
assignable to the Company will be issued in the U.S. or elsewhere. Moreover, the
issuance of a patent does not carry any assurance of successful application,
commercial success or adequate protection. There is no assurance that the
Company's existing patents or any other patent that may issue in the future
would be upheld if the Company seeks enforcement of its patent rights against an
infringer or that the Company will have sufficient resources to prosecute its
rights, nor is there any assurance that patents will provide meaningful
protection from competition.

The Company has been advised by its patent counsel, Thomas Plante, Esq., that no
adverse patent has been found which might create an infringement problem in the
marketing of the Company's products.  If others were to assert that the Company
is utilizing technology covered by patents held by them, the Company would
evaluate the necessity and desirability of seeking a license from the patent
holder.  There is no assurance that the Company is not infringing on other
patents or that it could obtain a license if it were so infringing.

Those products and improvements which the Company develops under government
contracts are generally subject to royalty-free use by the government for
government applications.  However, the Company has negotiated certain "non-
space" exclusions in government contracts and has the right to file for patent
protection on commercial products which may result from government-funded
research and development activities.

The Company has exclusive world-wide rights to technology developed under an
agreement with R & D Leasing, Ltd.  ("RDL"), a limited partnership.  Under the
agreement, the Company will pay royalties of 3.5% of all direct sales, by the
Company, of the basic devices using  the technology.  RDL will also receive 7%
of all income earned by the Company from sublicensees.  The Company's Chairman
of the Board and a Senior Vice-President have a beneficial interest in RDL.  See
"Development Contracts."

The Company has exclusive world-wide rights to U.S., United Kingdom and Japanese
patents covering the basic concept of the EFS pursuant to an agreement executed
in October 1997 with I. Sapir, a foreign individual ("Sapir"). Under this
agreement the Company issued 30,000 shares of common stock, and assumed an
obligation to pay a non-refundable $35,000 to Elba Systems LTD, a prior holder
of rights under the patent.  Imagek is the successor to the rights and
obligations of this licensing agreement pursuant to which EFS sales will bear a
3% royalty payable to Sapir on the gross sales price up to $50 million sales per
annum and  a 1% royalty thereafter.

The company has entered into an Assignment of Patent and Intellectual Rights
(the "Assignment") with F. L. Eide, ("Eide") a Vice-President of the Company. As
part of his employment agreement, Eide has assigned to the Company all rights
and interests to five (5) U.S. Provisional Patent applications owned by him.  In
consideration for this Assignment, Eide will receive a 1% royalty on the gross
sales revenues of any products incorporating elements of the assigned technology
for the lifetime of any patents resulting from the Provisional Patent
Applications.  This Assignment was executed in February 1998.
<PAGE>
 
The Company entered into a sale and licensing of intellectual property rights
related to the EFS to Advanced Technology Products, LLC ("ATPL"), a related
party which funded early development of this technology for which the Company's
Chief Technical Officer serves as Managing Member. In September 1998, the
Company assigned the rights and royalty obligations of the ATPL license to
Imagek. Concurrent with this assignment, ATPL reduced its royalty entitlements
under the license in consideration of the issuance of 1,221,875 shares of Imagek
common stock. ATPL retains a royalty entitlement of 2% of the first $30 million
of EFS sales, declining thereafter as a function of sales volume.


Environmental Matters
- ---------------------

The Company believes that it is substantially in compliance with all regulations
concerning the discharge of materials into the environment, and such regulations
have not had a material effect on the capital expenditures or operations of the
Company.


Employees
- ---------

As of September 27, 1998, the Company, including its consolidated subsidiaries,
had 68 full-time employees and 10 consultants.  Of the full-time employees, 46
were engaged in engineering, production and technical support, 4 in sales and
marketing and 18 in finance and administration.  None of the Company's employees
is represented by a labor union and the Company has experienced no work
stoppages due to labor problems.  The Company considers its employee relations
to be excellent.


The Year 2000
- -------------

The year 2000 issue is the result of computer programs using two digits, rather
than four to define the applicable year.  Programs that have time-sensitive
software may recognize a date using "00" as the calendar year 1900 rather than
the calendar year 2000.  Systems that do not properly recognize such information
could generate erroneous data or cause a system to fail.

The Company views the year 2000 problem as an important business issue that
could affect its business, as well as that of its suppliers and customers.
Until the last several years, the Company's business has primarily been R&D, and
its more recent business activities have not involved the shipment of products
or components with embedded controllers that might be affected by the Year 2000
problem.   However, Irvine Sensors' customers may have integrated the Company's
devices into higher level products or systems affected by the Year 2000 problem,
and, to the extent that its customers' business may be disrupted, the Company's
business and that of its subsidiaries is also subject to potential disruptions
from such a cause.

In addition, the Company does utilize a number of computerized information
systems to accurately process date-sensitive information across its operation,
and any of these programs or computer systems are potential sources of year 2000
system failures.  Irvine Sensors is working to identify and resolve such
potential impacts on the Company's computerized systems.  The Company has been
advised by its vendors that their systems will be compliant with year 2000
issues in a timely manner.

Finally, the Company's general business operations could be adversely impacted
were there to be material interruptions either in the country's banking or
financial systems or the procurement activities of its customers.  Irvine
Sensors has not completed its assessment of the full scope of these risks and
the actions necessary to address them, but the Company currently believes that
costs of addressing these issues will not have a material adverse impact on the
Company's financial position.  Nevertheless, if Irvine Sensors and third parties
upon which it relies are unable to address this issue in a timely manner, it
could result in a material financial risk to the Company.  In order to mitigate
the various risks associated with the Year 2000 problem, Irvine Sensors is
working with its suppliers and customers, including the disclosure and exchange
of relevant information, to proactively manage the calendar transition.

Factors that may affect Future Results
- --------------------------------------

The future operating results of the Company are highly uncertain, and the
following factors should be carefully reviewed in addition to the other
information contained in this annual report on Form 10-K and in other public
disclosures of the Company.

     Shift in Business Focus.  Since commencing operations, ISC has developed
technology, principally under government research contracts, for various
defense-based applications. Since 1992, ISC has been implementing a fundamental
shift in its business, broadening its focus to include commercial exploitation
of its technology. This shift has been manifested by the purchase and later shut
down of the IBM cubing line, the "carve-out" of the Novalog, MSI and Imagek
subsidiaries and the development of various stacked-memory products intended for
military and aerospace markets.  To date, these changes have developed new
revenue sources but have not yet produced sustained profitability.  Because of
this limited and not-yet successful history, there can be no assurances that
ISC's present and contemplated future products will be widely accepted in
commercial marketplaces.

     Financing Needs.  Although the Company believes that it has adequate 
liquidity for its present level of operations, ISC and its subsidiaries have
developed business plans for several emerging product areas based on its
technologies. The product development and market introduction costs of these
products cannot presently be fully funded from internal cash flow. There can be
no assurances that ISC or its subsidiaries will be able to locate external
financing for their business plans on acceptable terms.

     Nasdaq Listing Requirements.  ISC's Common Stock is publicly traded on the
Nasdaq SmallCap Market. Effective February 23, 1998, new and more restrictive
standards became effective for listing maintenance on this market. Prior to the
implementation of these new regulations, ISC briefly dropped below the pending
standards due to the loss associated with its Vermont plant closure and had to
establish to the satisfaction of the Nasdaq staff that it had met the new
standards in order to retain its listing. While the Company was able to meet
this requirement, there can be no assurances that the Company will be able to
maintain its compliance in the future. If ISC were to fail to meet the
maintenance requirements for listing on Nasdaq in the future and the price of
ISC's Common Stock was below $5 at such time, such securities would come within
the definition of "penny stock" as defined in the Securities Exchange Act of
1934, as amended (the "Exchange Act") and be covered by Rule 15g-9 of the
Exchange Act. That Rule imposes additional sales practice requirements on 
broker-dealers who sell such securities to persons other than established
customers and accredited investors. From transactions covered by Rule 15g-9, the
broker-dealer must make a special suitability determination for the purchaser
and receive the purchaser's written agreement to the transaction prior to the
sale. Consequently, Rule 15g-9, if it were to become applicable, would affect
the ability or willingness of broker-dealers to sell ISC's securities and
therefore would affect the ability of shareholders to sell their securities in
the public market and the Company's ability to finance its business plans.

     Dependence on Defense Contract Revenues.  Although ISC has been shifting
its focus to include commercial exploitation of its technology, it expects to
continue to be dependent upon research and development contracts with federal
agencies and their contractors for a substantial, but diminishing portion of its
revenues for the foreseeable future. General political and economic conditions,
which cannot be accurately predicted, directly and indirectly affect the
quantity and allocation of expenditures by federal agencies. Even the timing of
incremental funding commitments to existing, but partially-funded contracts can
be affected by such factors. Therefore, cutbacks in the federal budget could
have a material adverse impact on ICS's results of operations as long as
research and development contracts remain an important element of its business.

     Market Acceptance of New Products.  Both ISC and its subsidiaries are
focused on markets that are emerging in nature and potentially subject to rapid
growth. Market reaction to new products in such circumstances can be difficult
to predict.  There can be no assurance that the present or future products of
ISC or its subsidiaries will be favorably accepted by such markets on a
sustained basis.  In addition, because ISC has a limited history of competing in
the intensely competitive commercial electronics industry, there is no assurance
that it will successfully be able to develop, manufacture and market additional
commercial product lines or that such product lines will be accepted in the
commercial marketplace.

     Patents and Proprietary Right Protection; Infringement. ISC believes that
its ultimate success, and that of its subsidiaries, will depend, in part, on the
strength of its existing patent protection and the additional patent protection
that it and its subsidiaries may acquire in the future. As of the date hereof,
ISC owns 41 U.S. patents and 9 foreign patents and has other patent applications
pending before the U.S. Patent and Trademark Office as well as various foreign
jurisdictions.  Although ISC believes many of these patents to be 
<PAGE>
 
fundamental in nature, there can be no assurance that any existing or future
patents will survive a challenge or will otherwise provide meaningful protection
from competition. Furthermore, there is also no assurance that ISC or its
subsidiaries will have the financial resources to provide vigorous defense or
enforcement of patents.

     Protection of Proprietary Information. ISC and its subsidiaries treat
technical data as confidential and rely on internal nondisclosure safeguards,
including confidentiality agreements with employees, and on laws protecting
trade secrets, to protect proprietary information.  There can be no assurance
that these measures will adequately protect the confidentiality of the
proprietary information of ISC or its subsidiaries or that others will not
independently develop products or technology that are equivalent or superior to
those of ISC or its subsidiaries.  ISC or its subsidiaries may receive in the
future communications from third parties asserting that the products of ISC or
its subsidiaries infringe the proprietary rights of third parties.  There can be
no assurance that any such claims would not result in protracted and costly
litigation.  There can be no assurance that any particular aspect of the
technology owned by ISC or its subsidiaries will not be found to infringe the
products of other companies.  Other companies may hold or obtain patents or
inventions or may otherwise claim proprietary rights to technology useful or
necessary to ISC's or its subsidiaries' business.  The extent to which ISC or
its subsidiaries may be required to seek licenses under such proprietary rights
of third parties and the cost or availability of such license, cannot be
predicted.  While it may be necessary or desirable in the future to obtain
licenses relating to one or more of its proposed products or relating to current
or future technologies, there can be no assurance that ISC or its subsidiaries
will be able to do so on commercially reasonable terms.

     Government Rights.  Whatever degree of protection, if any, is afforded ISC
or its subsidiaries through its patents, proprietary information and other
intellectual property, this protection will not extend to government markets
that utilize certain segments of ISC's technology.  The government has the right
to royalty-free use of technologies which ISC has developed under government
contracts, including portions of ISC's stacked circuitry technology.  ISC is
free to commercially exploit such government-funded technologies and may assert
its intellectual property rights to seek to block other non-government users
thereof, but there can be assurances of success in such endeavors.

     Competition.  ISC and its subsidiaries face strong competition.  Most
competitors have considerably greater financial, marketing and technological
resources than does ISC or its subsidiaries.  There is no assurance that ISC or
its subsidiaries will be able to compete successfully with such other companies.

     Dependence on Suppliers.  ISC and its subsidiaries extensively use
suppliers in the manufacture of their products.  At the projected level of
operations, both ISC and its subsidiaries have identified sources that are
believed to be adequate to meet identified needs.  However, there is no
assurance that ISC or its subsidiaries will be able to cover changing
manufacturing needs in the future.  Failure to do so will have a material
adverse impact on the operations of ISC and its subsidiaries.

     Possible Technological Advances.  ISC and its subsidiaries are in
industries characterized by continuing technological development and,
accordingly, will be required to devote substantial resources to improve already
technologically complex products.  Many companies in these industries devote
considerably greater resources to research and development than does ISC or its
subsidiaries.  Developments by any of these companies could have a materially
adverse effect on ISC.

     Dependence on Key Personnel.  ISC and its subsidiaries will depend to a
large extent on the abilities and continued participation of certain key
employees.  The loss of key employees could have a material adverse effect on
the businesses of ISC and its subsidiaries. ISC and its subsidiaries have
adopted employee Stock Option Plans designed to attract and retain key
employees.  The value of such options to the subsidiaries will be strongly tied
to the timing of any future IPOs, of which there can be no assurance, and there
can, accordingly, be no guarantee of the efficacy of such options in retaining
key employees.  Neither ISC or its subsidiaries presently maintain "key man"
insurance on any key employees.  ISC believes that, as its activities and those
of its subsidiaries increase and change in character, additional, experienced
personnel will be required to implement the business plans of ISC and its
subsidiaries.  Competition for such personnel is intense and there is no
assurance that they will be available when required, or that ISC or its
subsidiaries will have the ability to attract them.
<PAGE>
 
The above factors are not intended to be inclusive.  Failure to satisfactorily
achieve any of the Company's objectives or avoid any of the above or other risks
would likely have a material adverse effect on the Company's business and
results of operations.

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Results of Operations

FISCAL YEAR ENDED SEPTEMBER 27, 1998 vs.
FISCAL YEAR ENDED SEPTEMBER 28, 1997

Revenues in fiscal 1998 of $9,314,500 decreased by $4,378,700 or 32 percent
compared to fiscal 1997. The primary reason for this decrease is attributed to
the closure of the Vermont facility. The decision to close the Vermont location
was centered on lower revenue and the continued increased cost of operations.
When considering corporate revenues generated by excluding the Vermont location,
fiscal 1998 revenues of $9,314,500 increased by $2,709,800 or approximately 41
percent.

Cost of contract revenues of $8,431,800 was 127 percent of contract revenues due
primarily to a substantial increase in reserves for potentially unsaleable
inventories. Cost of product sales of $2,247,000 or 98 percent of product sales
includes the final shut-down costs related to the Vermont facility. By
comparison, in fiscal 1997 cost of product sales were 150 percent of product
sales. Management is continuing to address the high product costs and believes
that gross margins will improve as sales increase and the effect of implemented
cost reductions are realized.

General and administrative expenses of $2,984,400 were reduced by $454,900 or 13
percent in relation to fiscal 1997. As a percentage of total revenues general
and administrative expenses were 32 percent in fiscal 1998 compared to 25
percent in fiscal 1997, however, fiscal 1997 included revenues from the Vermont
facility.

Research and Development decreased by $7,100 or less than 1 percent in the
year-to-year comparison. As a percentage of revenues R&D accounted for
approximately 17 percent in fiscal 1998 compared to approximately 12 percent in
fiscal 1997. The R&D expense in fiscal 1998 includes significant costs
associated with Imagek's development of the electronic film product.

The aggregate decrease of $7,356,300 in fiscal 1998 in cost of revenues, general
and administrative expenses and R&D are the direct result of management's
decision to streamline and control its expenses to fall in line with the reduced
revenue from the Vermont plant closing.

Interest expense declined by $177,400 in fiscal 1998, primarily attributable to
settlement of the Company's bank debt.

Interest income declined by $26,800 in fiscal 1998, primarily attributable to
lower interest rates and the debt pay-off associated with the Vermont facility.

The net loss of $4,243,500 in fiscal 1998 was $10,632,100, or 150 percent less
than fiscal 1997. The Vermont plant closing in fiscal 1997 accounted for
$5,873,400 or 55 percent of this reduced loss.
<PAGE>
 
FISCAL YEAR ENDED SEPTEMBER 28, 1997 vs.
FISCAL YEAR ENDED SEPTEMBER 29, 1996

Revenues in fiscal 1997 of $13,693,200 showed an increase of $1,669,000 or 14
percent compared to fiscal 1996. This increase was primarily attributable to the
Company's Advanced Technology Operations in Costa Mesa. In mid-fiscal year the
Company announced the closing of its Vermont facilities due to the lower than
required revenue base and high fixed cost of operations. In comparing revenues
generated by excluding the Vermont operations, fiscal 1997 revenues were
$6,604,700 compared to $5,460,300 in fiscal 1996, an increase of 21 percent.

Cost of revenues of $17,573,100 in fiscal 1997 was $435,500 higher than in
fiscal 1996; however, as a percentage of revenues, fiscal 1997 showed an
improvement of 14 percentage points over fiscal 1996. Operations excluding
Vermont recorded cost of revenues of $6,586,500 in fiscal 1997 compared to
$6,757,800 in fiscal 1996, a reduction of $171,300 or three percentage points.
In fiscal 1997, cost of revenues included a charge of $1,156,100 to increase the
Company's inventory reserve for, first: Wide Word SRAM memory cubes the Company
has been producing for future deliveries pursuant to an anticipated contract
which had not yet materialized and, second: slower than anticipated sales of its
Flash memory cubes.

General and administrative expenses were reduced by $592,300 in fiscal 1997
compared to fiscal 1996, and research and development expenses were also reduced
by $393,100 in fiscal 1997 compared to fiscal 1996.

These combined reductions of $1,156,700 in cost of sales, general and
administrative, and research and development reflect actual cost reductions
accomplished in fiscal 1997 while management re-structured the Company to take
advantage of new product opportunities and to expand the Company's traditional
customer R&Dbase.

With the decision to close the Vermont facilities, the Company incurred a loss
of $5,873,400 in fiscal 1997 related to the sale of the surplus facilities and
equipment.
<PAGE>
 
Interest income declined by $69,000 in fiscal 1997 primarily related to the
Vermont facilities.

The Company originally accounted for its convertible debentures in accordance
with APB 14, "Accounting for Convertible Debt and Debt Issued with Stock
Purchase Warrants." However, the Securities and Exchange Commission (SEC) staff
has indicated that convertible debt instruments which are convertible at a
discount from market should be accounted for by treating the maximum discount as
interest expense with an offset to paid-in capital. In November 1997, the
Company was advised that past issuers of such securities have recently restated
prior financial statements to comport with the SEC view. In conformance
therewith, the Company recorded noncash interest expense of $4,396,700
with a like amount added to paid-in capital in the second quarter of fiscal
1996. Because of the offsetting nature of these entries, there is no effect on
Shareholders' equity.

Net loss of $14,875,600 in fiscal 1997 was $1,039,100 lower than the net loss
reported for fiscal 1996. On a comparable basis, excluding plant closure costs
in fiscal 1997, and noncash debenture interest in fiscal 1996, the adjusted net
loss excluding the Vermont operations was $3,381,100 in fiscal 1997 compared to
$5,520,500 in fiscal 1996 - an overall improvement of $2,139,400.

Liquidity, Capital Resources and Impact of Changing Prices

The primary uses of cash and cash equivalents during fiscal 1998 were to
complete the winding down and exit from the Vermont facility, to retire the
Company's bank debt, reductions in trade payables and funding of the Company's
net loss, which also included R&D and start-up costs for its subsidiaries. As a
result of equity financings in fiscal 1998, these uses were accomplished while
improving the Company's working capital by $3,265,100.

At September 27, 1998, the Company had consolidated cash and cash equivalents of
$1,310,400, and subsequent to September 27, 1998, has obtained approximately
$540,000 cash in additional equity financing. The Company anticipates that the
existing working capital and its projected operating results will meet its cash
requirements for the immediate future.

Contracts with government agencies may be suspended or terminated by the
government at any time, subject to certain conditions. Similar termination
provisions are typically included in agreements with prime contractors. In 1983
the Company experienced such termination of one of its contracts. There is no
assurance the Company will not experience suspensions or terminations in the
future. Such termination, if material, could cause a disruption of the Company's
revenue stream and could result in employee layoffs.
<PAGE>
 
At September 27, 1998, the Company's funded backlog was approximately $1,897,800
compared to $1,902,800 at September 28, 1997. In addition, existing contracts
include a large amount of unfunded backlog which typically is funded when the
previously funded amounts have been expended. Subsequent to fiscal year end the
total backlog was $6,044,000 as of December 13, 1998.

Except for historical information contained herein, this Report contains
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934. The forward-
looking statements contained herein are subject to certain risks and
uncertainties, including such factors, among others, as the pace at which new
markets develop, the ability of the Company to introduce new products and ramp
up manufacturing in a timely manner while controlling its operating expenses and
the response of competitors, many of whom are bigger and better financed than
the Company. In addition, the scope of the Company's growth plan may introduce
unanticipated risks and financial requirements. The availability of external
financing for the Company's plan cannot be assured and is subject to numerous
factors including those unrelated to the Company's performance such as economic
and market conditions. Further, the Company's financial performance prior to
substantial growth in revenues may not permit additional equity financing and
may place at risk the continuation of its long-term debt financing because of
inability to achieve financial covenants. Accordingly, investors are advised to
assess forward-looking statements contained herein with caution. Additional
information on various risks and uncertainties potentially affecting the
Company's results are contained in publicly filed disclosures available through

Irvine Sensors Corporation
Notes to Consolidated Financial Statements
Note 1 - Summary of Significant Accounting Policies

CONSOLIDATION

The consolidated financial statements include the accounts of Irvine Sensors
Corporation (the Company) and its subsidiaries, Novalog, Inc. ("Novalog"),
MicroSensors, Inc. ("MSI"), 3D Microelectronics, Inc., 3D MicroSystems, Inc.,
and Imagek, Inc. ("Imagek"). Carson Alexiou Corporation ("CAC"), a former
subsidiary of the Company was dissolved in the current fiscal year. All
significant intercompany transactions and balances have been eliminated in
consolidation.

FISCAL YEAR

The Company's fiscal year ends on the Sunday nearest September 30. Fiscal 1998
(52 weeks) ended on September 27, 1998, fiscal 1997 (52 weeks) ended on
September 28, 1997, and fiscal 1996 (52 weeks) ended on September 29, 1996.

USE OF ESTIMATES

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates. The 
Company believes its estimates of inventory reserves and estimated costs to 
complete on contracts to be the most sensitive estimates impacting financial 
position and results of operations in the near term. 

REVENUES

The Company's revenues were derived from shipments of functional memory 
stacks, shipments of the SIRComm(TM) infrared chip and the development and
manufacture of prototype and sample products for its customers. The Company
continues to contract to develop prototypes and provide research, development,
design, testing and evaluation of complex detection and control defense systems.
The Company's R&D contracts are usually cost plus fixed fee (best effort) or
fixed price and revenues are recognized as costs are incurred and include
applicable fees or profits primarily in the proportion that costs incurred bear
to estimated final costs. Production orders for memory stacks and SIRComm chips
are generally priced in accordance with the Company's established price list.
The Novalog, MicroSensors and Imagek subsidiaries are product-oriented companies
with sales primarily to OEM manufacturers and revenues are recorded when
products are shipped.

The Company provides for anticipated losses on contracts by a charge to income
during the period in which they are first identified. Unbilled accounts
receivable are stated at estimated realizable value.

United States government contract costs, including indirect costs, are subject
to audit and adjustment by negotiations between the Company and government
representatives. Indirect contract costs have been agreed upon through fiscal
1996. Contract revenues have been recorded in amounts which are expected to be
realized upon final settlement.

Other revenues in fiscal 1998 were derived from the sale of intellectual
property to ATPL. (See Note 7 - Related Party Transactions.)

Other revenues in fiscal 1996 were derived from a licensing agreement with
Unitrode to transfer technology required to produce the Company's SIRCommchip.
(See Note 14 - Technology Licenses.)

RESEARCH AND DEVELOPMENT COSTS

A major portion of the Company's operations is comprised of customer-funded
research and prototype development or related activities. The Company also
incurs costs in research and development of new concepts in proprietary
products; such costs are charged to expense as incurred.

INVENTORY

Inventory is valued at the lower of cost or market. Cost is determined by the
first-in, first-out (FIFO) basis. Inventories are reviewed quarterly to
determine saleability and obsolescence. A reserve is established for slow moving
and obsolete items.

EQUIPMENT, FURNITURE AND FIXTURES

The Company capitalizes costs of additions to equipment, furniture and fixtures,
together with major renewals and betterments. In addition, the Company
capitalizes overhead for all in-house capital projects. Maintenance, repairs,
and minor renewals and betterments are charged to expense. When assets are sold
or otherwise disposed of, the cost and related accumulated depreciation are
removed from the accounts and any resulting gain or loss is recognized.

Depreciation of equipment, furniture and fixtures is provided over the estimated
useful lives of the assets, primarily using the straight-line method. The useful
lives are three to seven years. Leasehold improvements are amortized over the
terms of the leases.

<PAGE>
 
INCOME TAXES

Deferred tax assets and liabilities are recorded for differences between the 
financial statement and tax basis of the assets and liabilities that will result
in taxable or deductible amounts in the future based on enacted tax laws and 
rates applicable to the periods in which the differences are expected to affect 
taxable income. Valuation allowances are established when necessary to reduce 
deferred tax assets to the amount expected to be realized. Income tax expense is
recorded for the amount of income tax payable or refundable for the period 
increased or decreased by the change in deferred tax assets and liabilities 
during the period.

BASIC AND DILUTED NET LOSS PER SHARE

Net loss per share is calculated in accordance with Statement of Financial
Accounting Standards (SFAS) No. 128, "Earnings per Share," which supersedes APB
Opinion No. 15, "Earnings per Share." Net loss per share for all periods
presented has been restated to reflect the adoption of SFAS No. 128. Basic net
loss per share is based upon the weighted average number of common shares
outstanding. Diluted net loss per share is based on the assumption that options,
warrants, and convertible preferred stock are included in the calculation of
diluted earnings per share, except when their effect would be anti-dilutive.
Dilution is computed by applying the treasury stock method. Under this method,
options and warrants are assumed to be exercised at the beginning of the period
(or at the time of issuance, if later), and as if funds obtained thereby were
used to purchase common stock at the average market price during the period.

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income."
SFAS No. 130, which is effective for fiscal years beginning after December 15,
1997 and requires restatement of earlier periods presented, establishes
standards for the reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. Comprehensive
income is defined as the change in equity of a business enterprise during a
period from transactions and other events and circumstances from non-owner
sources. The implementation of SFAS No. 130 is not expected to have a material
effect on the Company's results of operations.

In June 1997,the FASBissued SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information." SFAS No. 131, which is effective for fiscal
years beginning after December 15, 1997 and requires restatements of earlier
periods presented, established standards for the way that a public enterprise
reports information about key revenue-producing segments in the annual financial
statements and selected information in interim financial reports. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. The implementation of SFAS No. 131 is not
expected to have a material effect on the Company's current reporting.

STATEMENT OF CASH FLOWS

For purposes of the Consolidated Statement of Cash Flows, the Company considers
all demand deposits and Certificates of Deposit with original maturities of 90
days or less to be cash equivalents.

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts reported in the balance sheet for cash and cash
equivalents, accounts receivable and payable, other liabilities and debt
approximate fair value. The fair value of royalties payable to affiliate is not
determinable due to their related party nature.

CONCENTRATION OF CREDIT RISK

The Company has cash deposits at U.S. banks and financial institutions, which
exceed federally insured limits at September 27, 1998. The Company is exposed to
credit loss for amounts in excess of insured limits in the event of non-
performance by the institution; however, the Company does not anticipate non-
performance.

ACCOUNTING FOR STOCK-BASED COMPENSATION

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS 123), which establishes financial accounting and reporting
standards for stock-based employee compensation. Under SFAS No. 123, companies
are encouraged, but not required, to adopt a method of accounting for stock
compensation awards based upon the estimated fair value at the date the
options/awards are granted as determined through the use of a pricing model (the
"Fair Value Method"). Companies continuing to account for such awards in
accordance with the existing guidance of Accounting Principles Board Option No.
25, "Accounting for Stock Issued to Employees" (APB 25), have to disclose in the
notes to their financial statements the pro forma impact on net income and net
income per share had they utilized the Fair Value Method. This statement became
effective for the Company in fiscal year 1997. The Company continues to account
for stock compensation awards in accordance with APB 25, with the appropriate
footnote disclosure required under SFAS 123.

IMPAIRMENT OF LONG-LIVED ASSETS

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, "Accounting For the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed Of" (SFAS 121), which
<PAGE>
 
establishes accounting standards for the impairment of long-lived assets to be
reviewed whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable. In addition, SFAS 121 requires that
certain long-lived assets be reported at the lower of carrying amount or fair
value less cost to sell. The Company adopted SFAS 121 in fiscal 1997. The
adoption of SFAS 121 had no significant impact on its consolidated financial
position or results of operations.

Note 2 - Issuance of Common Stock and Preferred Stock

During fiscal 1996, the Company issued 257,100 shares of common stock to seven
employees, two of whom are officers and one officer-director, and three non-
employee directors upon exercise of options granted under the Company's Stock
Option Plans. Net proceeds of $211,700 were added to the Company's general
funds.

In conjunction with a fiscal 1995 private financing of $2.25 million of 8
percent convertible subordinated debentures (the "1995 Debentures"), the Company
issued an additional $500,000 of 1995 Debentures in October 1995 (fiscal 1996)
to institutional investors in Europe. The gross proceeds less expenses were
added to the Company's general funds. During fiscal 1996, the Company, at the
request of bondholders, converted the entire $2.75 million of outstanding 1995
Debentures at varying rates into 509,400 shares of the Company's common stock,
which were subsequently registered and may be traded without restrictions.

In a private financing during February and March 1996, the Company issued $11.1
million of 8 percent convertible subordinated debentures due in 1998 (the "1996
Debentures") to institutional and private investors in Canada and Europe. The
1996 Debentures were convertible into shares of common stock at varying rates
which were contingent upon the closing bid prices of the common stock. The
Company had the right to demand conversion of the 1996 Debentures at any time
after March 1997. Interest was payable semiannually on January 31 and July 31 of
each year. The gross proceeds less expenses were added to the
Company's general funds.

During fiscal 1997, the Company, at the request of bondholders, converted
$3,150,000 of the outstanding 1996 Debentures at varying rates into 2,441,400
shares of the Company's common stock. With this conversion, all but $250,000
of the original issue of $11.1 million of the 1996 Debentures was retired. In
May 1996, the Company had registered the resale of 2,997,000 shares of common
stock which the Company then believed would be sufficient to cover the
conversion of the entire $11.1 million series of 1996 Debentures and related
warrants, which had been issued in February and March 1996. However, due to the
decline in the price of the Company's common stock, the number of shares issued
upon conversion of all the Debentures, exceeded the number of shares previously
registered. In January 1998 the Company filed a registration statement which
included the resale of 1,114,810 unregistered shares issued upon conversion of
the 1996 Debentures. This registration was declared effective by the Securities
and Exchange Commission in April 1998.

In January 1998, the Board of Directors authorized a contribution to the
Employee Stock Bonus Plan (the Company's ERISA-qualified Employee Retirement
Plan). The amount represents an annual contribution for fiscal year 1998 and was
made in 333,334 shares of the Company's common stock, which have been issued to
the Plan.

In fiscal 1998, the Company forced conversion of the remaining $250,000 of
outstanding 8 percent Convertible Subordinated Debentures into 100,000 shares of
the Company's common stock. The common shares underlying the convertible 
debentures were included in the Company's January 1998 registration statement.

The Company began the sale of Series D Convertible Preferred Stock Units in a
private placement to certain accredited investors in December 1997 and continued
to accept subscriptions thereto through January 2, 1998, at which time, the
Company sold an additional 24,750 Units. The Company issued an aggregate of
37,750 Units at a price of $100.00 per Unit and the net proceeds of $3,284,100
from the sale of these securities were added to the Company's general funds.

The Series D Convertible Preferred Stock Units consist of one share of
Convertible Preferred Stock, plus one five-year Warrant to purchase one share of
common stock of Novalog, Inc., a subsidiary of the Company, and one five-year
Warrant to purchase one share of common stock of Microsensors Inc., a wholly-
owned subsidiary of the Company. Each share of Convertible Preferred Stock is
convertible into common stock of the Company at the rate of 100 shares of Common
for each share of Preferred D, subject to adjustment for stock splits, reverse
stock splits and other similar recapitalization events. The Preferred D shares
have no voting rights, except as required by law, and bear no dividends. (See 
Note 17 for calculation of beneficial conversion and imputed dividend resulting 
from issuance of Series D Convertible Preferred Stock.) The common shares
underlying
<PAGE>
 
the Preferred D shares were included in the April 1998 registration statement.
In connection with this private placement of 37,750 units, the Company granted
to the placement agent a warrant to purchase up to 3,775 units of Series D
Convertible Preferred Stock units at a price of $110 per unit which was 110
percent of the private placement price of the Units. The warrant is exercisable
during the period beginning the earlier of one year from January 2, 1998 or the
date of registration and expiring on January 2, 2003. Warrants to purchase 500
units were exercised in May 1998 and the proceeds of $55,000 were added to the
Company's general funds.

As of September 27, 1998, at the request of the holders thereof, a total of
33,350 shares of Series D Convertible Preferred Stock have been converted into
3,460,300 shares of common stock.

In January 1998, the Company sold 125,000 Common Stock Units to investors in a
private placement. Each Common Stock Unit consists of one share of common stock
of the Company, plus one five-year Warrant to purchase one share of common stock
of Novalog, Inc., a subsidiary of the Company, and one five-year Warrant to
purchase one share of common stock of Microsensors, Inc., a wholly-owned
subsidiary of the Company. The proceeds of $125,000 from these transactions were
added to the Company's general funds.

In January 1998, a warrant holder exercised outstanding warrants to purchase
222,000 shares of common stock at a price of $1.00 per share. The proceeds from
this warrant exercise have been added to the Company's general funds.

In fiscal 1998, distribution of vested benefits was made from the Company's
Employee Retirement Plan to former employees. Subsequently, 1,819 shares of
Series B and 1,010 shares of Series C Convertible Preferred stock were
surrendered for conversion into 140,900 shares of common stock. The converted
Preferred shares have been retired.

In April 1998, the Company issued, in a private placement to accredited
investors, 700,000 unregistered shares of the Company's common stock. The net
proceeds of $980,000 from this private placement have been added to the
Company's general funds.

In August 1998, holders of 1,128,000 shares of common stock of Novalog exercised
warrants to exchange these shares for 905,000 unregistered shares of common 
stock of the Company resulting in an increase of $1,564,900 in total
shareholder's equity and a corresponding decrease in minority interest in
consolidated subsidiary.

In connection with settlement of bank debt, the Company issued 550,000 
unregistered shares of common stock in December 1997. (See Note 9 - Notes 
Payable.)

Note 3 - Common Stock Warrants

In July 1992, the Company consummated a public offering of 750,000 shares of
common stock and granted the Underwriter an option to purchase up to 112,500
additional shares of common stock to cover over-allotments. In connection with
this offering, the Company granted to the Underwriter warrants to purchase up to
75,000 shares of common stock at a price of $5.10 per share, which was 120
percent of the initial public offering price of the shares. The warrants were
exercisable during the four-year period beginning July 9, 1993, and expiring
July 8, 1997. During fiscal 1995, 57,800 of these warrants were exercised. The
remaining 17,200 were not exercised and expired on July 8, 1997.

In July 1993, the Company granted warrants to a consultant to purchase 30,000
unregistered shares of common stock at $8.875 per share, in connection with
services rendered. The shares underlying these warrants were registered in
fiscal 1995 and the price reduced to $4.50 per share. The warrants were
exercised in fiscal 1996.

In connection with the August 1995 sale of approximately 382,100 shares of
common stock and the issuance of approximately $2.75 million of the 1995
Debentures, the Company granted to the foreign investment banker warrants to
purchase up to approximately 79,700 shares of common stock at prices ranging
from $7.47 to $8.33 per share. In fiscal 1996, the price was reduced to $2.00
per share and the warrants were exercised.

In connection with the sale of $11.1 million of the 1996 Debentures in February
and March 1996, the Company granted warrants to the foreign investment banker to
purchase up to 222,000 shares of common stock at a price to be determined based
on the average conversion prices of the 1996 Debentures. The warrants were
exercised in fiscal 1998.

In fiscal 1997 the Company granted warrants, the value of which it believes to
be not material, to four consultants in varying amounts to purchase up to
118,000 shares of unregistered common stock at prices ranging from $0.9375 to
$1.50.

In fiscal 1998 the Company granted warrants, the value of which it believes to
be not material, to five former employees in varying amounts to purchase up to
44,000 shares of unregistered common stock at a price of $1.00.

As of September 27, 1998, there are a total of  162,000 warrants outstanding of
which 89,000 expire in the year 2000 and 73,000 expire in the year 2002.

Note 4 - Series B and Series C Convertible Preferred Stocks

The Series B and Series C Convertible Cumulative Preferred Stocks, which were
originally issued to the Company's Employee Retirement Plan, each bear a 10
percent cumulative annual dividend, which under Delaware law may generally be
paid only out of (i) retained earnings or (ii) net profit in the current or
preceding fiscal year. To the extent that the dividends are not declared and
paid in any fiscal year, the obligation carries over to the next fiscal year.
These shares of Series B and Series C 
<PAGE>
 
Convertible Cumulative Preferred Stocks are not redeemable, carry a liquidation
preference over the common stock of $15.00 and $30.00, respectively, per share
and are convertible, at the option of the holder, into 50 shares of common stock
for each share of Series B and Series C Convertible Cumulative Preferred Stock,
respectively. Distributions of vested benefits made from the Plan to former
employees and the subsequent surrender and conversion into shares of common
stock are as follows:

                           Preferred Stock     Common
                         Series B   Series C    Stock
- ------------------------------------------------------
Distribution dates:
Fiscal 1996                   522        480    50,100
Fiscal 1997                    48        204    12,600
Fiscal 1998                 1,819      1,010   140,900
                            2,389      1,694   203,600
======================================================

The shares of Preferred Series B and Series C tendered for conversion have been
retired.
Undeclared dividends of $94,000 and $95,100 on the remaining outstanding
Preferred Series B and Series C, respectively, will be carried forward to fiscal
1999.

Note 5 - Preferred Stock of Consolidated Subsidiary

The preferred stock outstanding represents an ownership interest in Carson
Alexion Corporation ("CAC"), a former subsidiary of the Company, by former
employees and an Employee Stock Bonus Plan which CAC had formed. The preferred
stock had a $100 par value and there were 1,400 shares authorized and 1,185
shares issued and outstanding at September 28, 1997. There were no conversion
rights or liquidation preferences of this preferred stock which extended to the
common stock of the Company. CAC has been inactive since 1985 and in August
1998, CAC was dissolved by the Massachusetts Commissioner of Corporations. The
outstanding preferred shares were retired and the outstanding balance was added
to the paid-in capital.

Note 6 - Convertible Subordinated Debentures

In July, August and October 1995, the Company issued in a private financing
$2.75 million of 8 percent convertible subordinated debentures (the "1995
Debentures") due in 1997 to institutional and private investors in Canada and
Europe. The 1995 Debentures were convertible into shares of common stock at
$6.50 per share, subject to adjustment under certain conditions. The Company had
the right to demand conversion of the 1995 Debentures at any time after July 31,
1996. Interest was payable semi-annually on January 31 and July 31 of each year.
The 1995 Debentures were subordinated to prior payment of bank indebtedness of
the Company. The gross proceeds less expenses were added to the Company's
general funds. The Company registered the shares underlying the 1995 Debentures
and in fiscal 1996 the 1995 Debentures were converted into 509,400 shares of the
Company's common stock. (See Note 2.)

In a private financing during February and March 1996, the Company issued $11.1
million of 8 percent convertible subordinated debentures due in 1998 (the "1996
Debentures") to institutional and private investors in Canada and Europe. The
1996 Debentures were convertible into shares of common stock at varying rates
which were contingent upon the closing bid prices of the common stock. The
Company had the right to demand conversion of the 1996 Debentures at any time
after March 1997. Interest was payable semiannually on January 31 and July 31 of
each year. The 1996 Debentures were subordinated to prior payment of bank
indebtedness of the Company. The gross proceeds less expenses were added to the
Company's general funds. (See Note 2).

The Company originally accounted for its convertible debentures in accordance
with APB 14, "Accounting for Convertible Debt and Debt Issued with Stock
Purchase Warrants." However, the Securities and Exchange Commission (SEC) staff
has indicated that convertible debt instruments which are convertible at a
discount from market should be accounted for by treating the maximum discount as
interest expense with an offset to paid-in capital. In November 1997, the
Company was advised that past issuers of such securities had restated prior
financial statements to comport with the SEC view. In conformance therewith, the
Company recognized noncash interest expense of $4,396,700 with a like amount
added to paid-in capital in the second quarter of fiscal 1996. Because of
the offsetting nature of these entries, there was no effect on Shareholders'
equity.

During fiscal 1997, the Company, at the request of bondholders, converted
$3,150,000 of the outstanding 1996 Debentures at varying rates into 2,441,400
shares of the Company's common stock. With this conversion, all but $250,000
of the original issue of $11.1 million of the 1996 Debentures was retired. In
fiscal 1998, the Company forced the conversion of these remaining 1996
Debentures into 100,000 shares of common stock. In May 1996, the Company had
registered the resale of 2,997,000 shares of common stock which the Company then
believed would be sufficient to cover the conversion of the entire $11.1 million
series of 1996 Debentures and related warrants, which had been issued in
February and March 1996. However, due to the decline in the price of the
Company's common stock, the number of shares issued upon conversion of all the
Debentures, exceeded the number of shares previously registered. In January 1998
the Company filed a registration statement which included the resale of
1,114,810 unregistered shares issued upon conversion of the 1996 Debentures.
This registration was declared effective by the Securities and Exchange
Commission in April 1998.

Note 7 - Related Party Transactions

In April 1980, the Company entered into an agreement with R & D Leasing Ltd. 
("RDL"), a limited partnership in which the Company's Chairman of the Board and 
a Senior Vice-President are general partners with beneficial interests, to 
develop certain processes and technology related to chip stacking. The Company 
has exclusively licensed this technology from RDL. The Company's exclusive 
rights to the technology extend to all uses, both government and commercial. 
Since entering into the licensing agreement, the Company has accrued royalty 
obligations to RDL at the rate of 3.5% of all Company sales of chip stacks using
the licensed technology. In addition, RDL is entitled to receive an amount equal
to 7% of all royalties earned by the Company from sales of any such products by 
the Company's sublicensees, although to date, no such sublicensee royalty income
has been earned. In October 1989, RDL agreed to defer its royalty claims and
subordinate them with respect to all other creditors in exchange for options to
purchase up to 1,000,000 shares of the Company's Common Stock, which are
exercisable by applying the deferred royalties to the purchase. The 1,000,000
options are exercisable at $1.00 until October 1999. If RDL exercises its option
in whole or in part, title to RDL's technology would transfer to the Company and
all further royalty obligations would cease. If the option expires unexercised,
the subordination provisions would terminate and the accrued royalties would be
due and payable in the same manner as any other corporate obligation. As of
September 27, 1998, the Company had accrued $826,200 in deferred royalties
pursuant to this agreement. Due to the RDL subordination, royalties accrued, but
none were paid by the Company during fiscal years 1998, 1997 and 1996.

The company has entered into an Assignment of Patent and Intellectual Rights
(the "Assignment") with F.L. Eide ("Eide"), a Vice-President of the Company. As
part of his employment agreement, Eide has assigned to the Company all rights
and interests to five (5) U.S. Provisional Patent applications owned by him.In
consideration for this Assignment, Eide will receive a 1 percent royalty on the
gross sales revenues of any products incorporating elements of the assigned
technology for the lifetime of any patents resulting from the Provisional Patent
Applications. This Assignment was executed in February 1998.

The Company entered into a sale and licensing of intellectual property rights
related to the Company's Electronic Film System(TM) ("EFS(TM)") to Advanced
Technology Products, LLC ("ATPL"), which funded early development of this
technology and for which the Company's Chief Technical Officer, John C. Carson,
serves as Managing Member. Imagek is the successor to the royalty obligations
under this license. In September 1998, an agreement was consummated with ATPL
under which the royalty obligation was reduced in consideration of the issuance
of 1,221,875 shares of Imagek common stock.

======================================================================

In December 1997, the Company executed a Forbearance Agreement with its lending
bank whereby the Company agreed to accelerate repayment of the Note Payable to
the bank. The current portion of the debt was reduced by $1,026,900 which was 
received from the sale of the assets in October 1997. The Company also agreed,
among other requirements, to reduce the principal balance by payments of
$250,000 in each of the calendar quarters ending December 1997 and March 1998
and thereafter to reduce the remaining balance by a minimum of $200,000
quarterly. Execution of the Forbearance Agreement also resulted in a waiver of
the Company's then financial covenant defaults and an amendment to the loan
agreement eliminating such financial covenants on a prospective basis. In
connection therewith, the Company pledged as collateral one million shares of
Novalog, Inc. common stock held by the Company. The Company also paid down
$500,000 of the Note with 550,000 shares of its stock and under the terms of the
agreement, dependent on the market price of the shares when sold, the Company
would receive a refund if the proceeds from the sale exceeded $500,000.
Subsequently, the Company was informed by the bank that it sold the 550,000
shares and that the proceeds exceeded $500,000. After applying the proceeds to
the then remaining balance of
<PAGE>
 
the note the bank, through September 27, 1998, remitted $772,000 to the Company
and advised the Company that additional proceeds of $183,000 were to be remitted
to the Company. These additional funds have subsequently been received by the
Company. The Company recorded the proceeds that exceeded $500,000 as paid-in
capital.

Note 10 - Income Taxes

Deferred tax assets and liabilities are recorded for differences between the
financial statement and tax basis of the assets and liabilities that will result
in taxable or deductible amounts in the future based on enacted tax laws and
rates applicable to the periods in which the differences are expected to affect
taxable income. Valuation allowances are established when necessary to reduce
deferred tax assets to the amount expected to be realized. Income tax expense is
recorded for the amount of income tax payable or refundable for the period
increased or decreased by the change in deferred tax assets and liabilities
during the period.

The tax effects of significant items comprising the Company's deferred tax
calculation as of September 27, 1998 and September 28, 1997 are as follows:

                                                         1998            1997

=============================================================================

The differences between the Company's effective income tax rate and the
statutory U.S. federal income tax rate for the fiscal years September 27, 1998,
and September 28, 1997, respectively, are as follows:

The total valuation allowance changed $334,000 from September 28, 1997, to
September 27, 1998.

The provisions for income taxes for the fiscal years ended September 27, 1998,
September 28, 1997, and September 29, 1996, consist of provisions for state
income taxes of $2,600, $2,600 and $1,800, respectively. No provisions for
federal income taxes have been made in these fiscal years due to the net
operating losses.

At September 27, 1998, the Company had net operating loss carryforwards of
approximately $46,223,000 for financial reporting and federal income tax
purposes expiring in varying amounts from fiscal year 1999 through fiscal year
2013, and $11,844,000 for California tax purposes expiring in varying amounts
from fiscal year 1999 through fiscal year 2003, available to offset future
federal and California taxable income. In addition, as of September 27, 1998,
the Company had investment tax credits and qualified research credits of
$286,000 and $255,000, respectively, expiring in varying amounts through fiscal
year 2009 and available to offset future federal and California taxes. The
ability of the Company to utilize the net operating loss and credit
carryforwards may be restricted by certain provisions of the Internal Revenue
Code.

Note 11 - Operating Leases

The Company leases certain facilities and equipment under cancelable and
noncancelable lease obligations. Total rental expense for operating leases
amounted to $559,000, $1,685,200 and $1,633,500 for the fiscal years ended
September 27, 1998, September 28, 1997, and September 29, 1996, respectively.
Minimum lease commitments existing at September 27, 1998, are approximately as
follows:

Fiscal years ending:

  1999                        $  427,900
  2000                           397,100
  2001                           403,000

Note 12 - Stock Option Plans and Employee Retirement Plan

In December 1991, the Board of Directors adopted the 1991 Stock Option Plan to
replace 1981 Stock Option Plans, which had expired. This new Plan was approved
by shareholders at the Company's Annual Meeting in February 1992. Under the 1991
Plan, options to purchase an aggregate of 675,000 shares of the Company's common
stock may be granted to both key management employees and non-employee
directors. Options granted may be either Incentive Stock Options or Nonstatutory
Stock Options and the requirements for participation, exercise price and other
terms are similar to the 1981 Plans. As of September 27, 1998, options to
purchase 259,800 shares at prices ranging from $1.4375 (40,000 shares) to $7.75
(8,300 shares) were outstanding under the 1991 Plan, of which 46,800 were
exercisable at September 27, 1998.

In January 1995, the Board of Directors adopted the 1995 Stock Option Plan to
replace the 1991 Plan, which was fully subscribed at the time. The 1995 Plan was
approved by shareholders at the Company's Annual Meeting in February 1995. Under
the 1995 Plan, options to purchase an aggregate of 700,000 shares of the
Company's common stock may be granted to both key management employees and non-
employee directors. In August 1997, the Board of Directors authorized an
increase in the number of options to an aggregate of 1,650,000 shares, and this
increase was ratified by shareholders at the Company's Annual Meeting in
February 1998. Options granted may be either Incentive Stock Options or
Nonstatutory Stock Options, and requirements for participation, exercise price
and other terms are similar to the 1991 Plan. As of September 27, 1998, options
to purchase 1,641,000 shares at prices ranging from $0.98 (580,000 shares) to
$6.50 (10,000 shares) were outstanding under the 1995 Plan, of which 372,800
were exercisable at September 27, 1998.

In November 1998, the Board of Directors approved a new plan, "The 1999 Stock
Option Plan," subject to ratification by shareholders at the Company's Annual
Meeting in February 1999. Under the 1999 Plan, options to purchase an aggregate
of 1,000,000 shares of common stock may be granted to both key management
employees and non-employee directors.

Stock option activity is summarized as follows:

</TABLE> 

Pursuant to SFAS No. 123 "Accounting for Stock Based Compensation," the Company
is required to disclose the effects on the net loss and per share data as if the
Company had elected to use the fair value approach to account for all of its
employee stock-based compensation plans. Had the compensation cost for the
Company's Plans been determined using the fair value method, the compensation
expense would have had the effects of increasing the Company's net loss for the
years ended September 27, 1998, September 28, 1997, and September 29, 1996 to
the pro forma amounts of $4,754,000, $15,041,000, and $16,255,700 respectively,
with a corresponding pro forma loss per share of $0.19, $0.73, $0.96,
respectively. These pro forma amounts were determined estimating the fair value
of each option granted during fiscal 1996, fiscal 1997 and fiscal 1998 on its
grant date, using the Black-Scholes option-pricing model. Assumptions of no
dividend yield, a risk-free interest rate of 6 percent which approximates the
Federal Reserve Board's rate for treasuries at the time granted, an expected
life of three years, and volatility rates varying from 86.9 to 73.2 percent were
applied to options granted during fiscal years 1998 and 1997, and 1996. The
weighted average fair value at the grant date for the options granted during
fiscal years 1998, 1997, and 1996 was $1.57, $0.75 and $3.47 per option,
respectively.

In fiscal 1982, the Company established an Employee Retirement Plan, which is
effective for fiscal year 1982 and thereafter. The plan provides for annual
contributions to the Company's Stock Bonus Trust (SBT) to be determined by the
Board of Directors and which will not exceed 15 percent of total payroll. At the
discretion of the Trustee, the SBT will purchase common stock at fair market
value or other interest-bearing securities or investments for the accounts of
individual employees who will gain a vested interest of 20 percent in their
accounts after three years of service, and 20 percent each year of service
thereafter, until fully vested after seven years of service. That portion of
cash or stock held in an employee's account and not vested at termination of
employment will be redistributed in accordance with a prearranged formula.
Management believes that the contributions made by the Company to the SBT, to
the extent they relate to government cost-plus-fixed-fee contracts, will be
reimbursable by the U.S. government. In fiscal years 1996, 1997 and 1998 the
Company's contributions to the SBT were 172,900, 347,600 and 333,300 shares of
common stock, respectively, which had estimated market values of $687,400,
$445,500 and $500,000 respectively.

Note 13 - Revenues

In fiscal 1998, contracts with all branches of the U.S. government accounted
for 27 percent of the Company's revenues, and a second-tier government contract
with a prime government contractor accounted for 27 percent. The remaining 46
percent of the Company's revenues were derived from non-government sources. Of
the 27 percent related to the U.S. government agencies, the U.S. Army, the U.S.
Air Force and the U.S. Navy accounted for 24 percent, 12 percent and 8 percent,
respectively, with the remaining revenue of 56 percent being widely diversified
among several other governmental agencies.

Of the 46 percent applicable to non-governmental sources, three (3) customers
accounted for 35 percent, 14 percent and 7 percent, respectively, of the total
commercial revenues.

In fiscal 1997, contracts with all branches of the U.S. government accounted for
43 percent of the Company's revenues, and the remaining 57 percent of the
Company's revenues was derived from non-government sources. Of the 43 percent
applicable to the U.S. government, there were three agencies of the government
that accounted for 55 percent, 13 percent and 11 percent. Other government
agencies accounted for the remaining 21 percent. Of the 57 percent applicable to
non-government sources, two customers accounted for 49 percent and 39 percent of
the revenues.

In fiscal 1996, contracts with all branches of the U.S. government accounted for
31 percent of the Company's revenues, and the remaining 69 percent  of the
Company's revenues was derived from non-government sources. Of the 31 percent
applicable to the U.S. government, there was one agency of the government that
accounted for 16 percent. Other government agencies 
<PAGE>
 
accounted for the remaining 15 percent. Of the 69 percent applicable to non-
government sources, two customers accounted for 23 percent and 21 percent of the
revenues.

Note 14 - Technology Licenses

In June 1992 the Company and International Business Machines (IBM) entered into
an agreement to develop manufacturing technology required to commercially
produce parts using the Company's technology for stacking integrated circuits.
In June 1993, IBM and the Company jointly announced the opening of a pilot
manufacturing line at an IBM facility. The agreement provided for the Company to
receive royalties on stacked chip parts sold by IBM and will share equally with
IBM any royalties received from the licensing of the jointly developed
manufacturing technology. In April 1996, the Company reached an agreement with
IBM wherein the Company acquired the operating line from IBM and leased the
facilities. This agreement was terminated in fiscal 1997.

In May 1995, the Company and Unitrode Corporation (Unitrode) entered into an
agreement to transfer to Unitrode the technology required to produce the
Company's wireless infrared communication integrated circuit (SIRComm). The
Company will receive licensing and royalty payments for the technology transfer
and on SIRComm products sold by Unitrode.

Note 15 - Deferred Revenues

The Company received prepayments from customers related to services and products
which had not been delivered as of the balance sheet date. Revenues are recorded
upon delivery of these services and products.

Note 16 - Acquisition and Disposal of Equipment

On April 19, 1996, the Company consummated an agreement for the acquisition and
operation of the equipment comprising IBM's cubing line located at IBM's Essex
Junction, Vermont facility. The cubing line was established by IBM to
manufacture the stacked-chip assemblies required to commercialize the Company's
proprietary chip-stacking technology under the joint development alliance that
IBM and the Company entered into in 1992. According to the terms of the
agreement, the Company acquired the equipment and clean room, which comprises
the cubing line for a cash payment of approximately $6.5 million. In addition,
the Company signed a facility lease agreement for the space required to operate
the cubing line under the Company's management within the IBM facility through
December 1998. The terms of the facility lease agreement include escalating rent
payments, which have been straight lined for financial reporting purposes. The
difference between the amount paid and the amount expensed during fiscal 1996
has been reported as accrued rent. The agreement was terminated in fiscal 1997
and the deferred rent balances were netted against rent expense.

As part of the process to terminate the agreement with IBM, the Company disposed
of the equipment acquired from IBM in April 1996 and other fixed assets
purchased and/or constructed at the IBM facility. These assets with a net book
value of $6,925,300 were sold for proceeds of $1,051,900, resulting in a loss on
the disposal of $5,873,400. At September 28, 1997, $1,026,900 of those proceeds
was still receivable and is included in Other current assets on the balance
sheet. During October 1997, these proceeds were received by the Company's lender
and applied against the principal of the Company's long-term debt. (See Note 9).

In December 1997, the Company made a $490,000 cash payment to extinguish its
remaining obligations under a Settlement Agreement. Accordingly, the Company
recorded an extraordinary gain of $1,146,100 on the extinguishment of debt and
reduced accounts payable by the corresponding amounts.

Note 17 - Earnings Per Share

As the Company had a net loss from continuing operations for 1998, 1997 and
1996, basic and diluted net loss per share are the same.

Net loss applicable to common stockholders includes $465,300 for the non-cash 
imputed dividend related to the beneficial conversion feature on 24,750 Units of
the Series D Convertible Preferred stock. (See Note 2). The beneficial 
conversion feature is computed as the difference between the quoted market price
of a share of common stock on date of issue and the conversion price times all 
shares of preferred stock sold and under option. The imputed dividends are a 
non-cash, one-time charge based on the immediate conversion feature.

Basic and diluted net loss per common share for 1998, 1997 and 1996 were
calculated as follows:

Note 18 - Fourth Fiscal Quarter Adjustments

The Company's fiscal year end coincides with the Federal budgetary process
providing additional clarification regarding the utility of the Company's
inventory. Accordingly, management performs a comprehensive review of its
inventory in the fourth quarter. Additionally, in the fourth quarter of fiscal
1998, the Company's analysis of organization and financing activities of the
Company's Imagek subsidiary resulted in adjustments to the accounting for
allocation of cash received and certain expenses. Also, subsequent to the close
of the fiscal year, the Company completed a technical analysis of the
transaction settling its bank debt, resulting in a determination to reclassify
the proceeds therefrom as additional paid-in capital rather than gain from debt
extinguishment. Significant adjustments made in the fourth quarter are
summarized below. Certain of these adjustments will result in adjustments to
previously released financial information for earlier quarters of fiscal 1998.
The Company is in the process of evaluating these effects and expects to amend
its reports for the affected periods.

Inventory write-offs and reserves                          $2,079,000
Reclassification of gain on debt extinguishment
  to additional paid-in capital                               954,800
Inventory costs charged to R&D expense                        795,000
Additional depreciation of equipment, furniture & fixtures    310,000
