                                     PART I

ITEM 1.  BUSINESS

GENERAL

Advanced Photonix, Inc.(R) (hereafter referred to as the "Company"), is engaged
in the development and manufacture of optoelectronic semiconductor based
components, hybrid assemblies and other proprietary solid state light and
radiation detection devices, including proprietary advanced solid state silicon
photodetection devices which utilize avalanche photodiode ("APD") technology.
The Company was incorporated under the laws of the State of Delaware on June 22,
1988. The Company believes that its proprietary APD technology represents a
leading-edge advancement in photodetection and imaging that will become an
increasingly important part of its business.

The Company's proprietary technology extends the capability of the traditional
APD by introducing a large surface area silicon device or large area avalanche
photodiode ("LAAPD"). The Company developed the LAAPD as an alternative to the
photomultiplier vacuum tube ("PMT"), which has been used for many years as the
primary technology for certain measurement, control and monitoring applications
in industrial, medical, military, scientific and commercial settings.

The LAAPD is an advanced photodetection device developed for the photonics
industry specifically as a replacement to the outdated PMT. Photodetection
devices sense light of varying intensity and convert the light detected to
electronic signals that cause the systems of which they are a part to respond in
pre-determined ways. The photonics industry includes other devices less complex
than the LAAPD such as PIN (positive-intrinsic-negative) photodiodes. Currently
the bulk of the Company's revenues are derived from the sale of products based
on PIN and other non-proprietary technologies, referred to as the "core
business".

PRODUCTS

The Company designs and manufactures optoelectronic semiconductor based
components and hybrid assemblies. The Company's most notable products include:

-   Customer specific assemblies for fiber-optic data and telecommunications,
    medical/biological diagnosis, particle measuring and counting

-   PIN photodetectors, spectrally enhanced, single and multi-element

-   Photodetector hybrids

-   Military and commercial aerospace products

-   Custom optoelectronic assemblies incorporating light-emitting diodes
    ("LEDs") and LED displays

-   FILTRODE(R) - patented technology integrating optical filters directly on
    photodiode chips

-   Avalanche photodiodes

-   Large area avalanche photodiodes (LAAPDs - discrete, with and without
    amplification, and with and without thermoelectric coolers)

The Company supplies detectors for military and commercial aerospace and other
high reliability ("Hi-Rel") applications. Hi-Rel devices are designed,
manufactured, and tested to function in severe environmental conditions. The
Company has many years of experience in supplying Hi-Rel devices that demand
modern wafer fabrication techniques, a dedicated assembly area, and a
sophisticated test lab. Hi-Rel products manufactured by the Company include:



                                       2
<PAGE>   3

-   Multi-element hybrid assembly used on the U.S. Navy's Rolling Airframe
    Missile (RAM) developed by Raytheon

-   Narrow and wide field of view detectors used in various TOW missile tracking
    systems

-   LED arrays for use in thermal image displays in various night sights,
    commercial and military

-   Quadrant photodetectors used in the autocollimator for airborne
    navigation/FLIR POD's and "Smart Bombs"

-   Multi-element detector arrays used in the Space Shuttle Arm control system
    and satellite systems

-   Opto assemblies for biological and blood analysis

-   Automotive distance control

The Company's patented FILTRODE(R) technology integrates optical coatings
directly on photodiode chips, replacing conventional technology that requires a
separate filter glass. While the technology offers a simpler design and lower
cost, reliability and performance are improved due to the integrated design.
Special packaging of this technology allows for unique applications whereby both
sides of the detector can be used to detect light.

The Company's small area avalanche photodiodes ("SAAPDs" -- see description of
avalanche photodiode technology below) utilize a silicon epi-planar structure.
SAAPDs have been used for a variety of low-light level applications and are
responsive from 400 nm to 1000 nm. Typical applications include fiber optics and
free space communications, bar code readers and laser range finders.

LARGE AREA AVALANCHE PHOTODIODE TECHNOLOGY

The avalanche photodiode is a specialized silicon photodiode capable of
detecting very low light levels due to an internal gain phenomenon known as
avalanching. This performance characteristic is not present in the common PIN
photodiode.

The APD, developed in the late 1960's, gave promise of a solid state replacement
for the photomultiplier tube, an old and outdated vacuum tube technology, for
sensing low levels of energy. Historically, APDs have been 3mm diameter or
smaller with an internal gain of 50:1 or less. Until now, design and
manufacturing limitations have restricted the size and performance of APDs,
severely limiting their practical use.

The Company has developed and patented various attributes of the LAAPD, most
notably producing diameters up to 25 mm with internal gains of 300:1. The LAAPD
is a high speed detector capable of detecting low light levels from the DEEP UV
(ultraviolet), through the visible spectrum and into the near IR (infrared).
When coupled with a scintillator, the LAAPD can efficiently detect X-ray and
gamma-rays. It is also sensitive to accelerated electrons with potentials
greater than a few thousand electron-volts. The LAAPD offers capabilities well
beyond those of the existing photo-detection devices, such as the PIN
photodiode, the small area APD and the PMT. Advantages over PIN photodiodes
include higher sensitivity at wider bandwidths. Advantages over small area APDs
include larger active areas with much greater sensitivity and gain. The LAAPD's
advantages over PMTs include superior spectral bandwidth, greater sensitivity to
pulses above 500 photons especially in the visible and near IR, greater dynamic
range, and a rugged, solid-state structure suitable for operation in harsh
environments. LAAPDs feature superior quantum efficiency in visible, near IR and
UV regions to that of the PMT. Other features that differentiate the LAAPD from
the PMT include its small package size, immunity to magnetic fields and ease of
temperature control, providing stable operation over temperature gradients. In
addition to a rugged and compact design, their operation requires far less
power, making the LAAPD more advantageous in portable applications.

The Company expects, but there is no assurance, that its proprietary APD
technology, employed in the development of the LAAPD, will form the basis for
continuing the investigation and potential commercial development of other



                                       3
<PAGE>   4

lines of advanced silicon avalanche photonics products that will have a broader
range of commercial and military applications than the PMT and PIN arrays. For
example:

-    LAAPD arrays - the Company's patented technology in which the rear surface
     of an LAAPD is segmented to create isolated pixels, each with a separate
     electronic lead to be accessed in parallel fashion for imaging
     applications.

-    Vacuum avalanche photodiode (VAPD) - another patented technology, which
     combines a photocathode and an LAAPD in a vacuum tube, functioning as a
     detector for high resolution, single photon-counting and low light level
     detection.

The Company has identified target markets for its LAAPD products based on
customer evaluations and in-house tests. Evaluation detectors are sold to
original equipment manufacturers ("OEMs"), engineers and scientists who report
information to the Company concerning potential applications and markets, as
well as suggesting improvements and pricing objectives. It is expected, but
there is no assurance, that OEMs who can take advantage of the performance
capabilities of LAAPDs will be the source of repeat business for production
quantities. Targeted markets include:

-   Ranging, tracking & imaging - smart image surveillance/security cameras, 3D
    collision avoidance cameras, missile guidance, threat warning, underwater
    mine detection, and mapping & salvaging.

-   Medical imaging - detectors which image human physiology in slices and look
    for pathology. Included in this category are PET scanners, CT scanners, bone
    densitometers and gamma cameras.

-   Industrial scanning/process control - industrial CT inspection, aerospace
    ice inspection, drum/flat bed scanning, semiconductor wafer defect scanning
    and film to video conversion.

-   Analytical chemistry - analyzing the chemical "recipe" of samples, from
    glucose levels in the blood to pesticides in ground water.

-   Medical diagnostics - human fluids are analyzed to diagnose a medical
    pathology or condition. A partial list of conditions which are diagnosed
    every day using photonics technology includes diabetes, lipid metabolism
    disorders, myocardial infarction, gout, liver diseases, renal diseases,
    pancreatitis, anemia, and electrolyte disturbances. It is expected that this
    list will grow dramatically in the coming years with the explosion of
    methods now available to perform immunodiagnostics. Examples of forthcoming
    diagnostics include those targeting thyroid and sexually transmitted disease
    conditions and wide field retinal visualization.

-   Environmental monitoring - atmospheric meteorology LIDAR (light detection
    and ranging), radiation dose monitors, airborne and liquid particle
    measurement, optical air data systems, airport wind shear, atmospheric
    pollution monitoring.

-   Scientific research - high energy physics fiber tracking, space particle
    experiments and neutrino experiments.

The Company's products are primarily sold as components or assemblies to OEMs or
other component manufacturers. The Company does not manufacture any end user
products within the above or any other markets.

RAW MATERIALS

The principal raw materials used by the Company in the manufacture of its
semiconductor chip components and assemblies are silicon wafers, chemicals and
gases used in processing wafers, gold wire, lead frames, metal and plastic
packages that house the chip and the various custom assemblies. All of these raw
materials can be obtained from several suppliers. From time to time,
particularly during periods of increased industry-wide demand, silicon wafers
and other materials have been in short supply. However, the Company has not been
materially affected by such shortages. As is typical in the industry, the
Company allows for a significant lead-time between order and delivery of raw
materials.

RESEARCH AND DEVELOPMENT

The Company undertakes both internally funded and customer funded research and
development programs when they are in support of the Company's development
objectives. Since its inception in June 1988, the Company has incurred material
amounts of research and development expenses. During the fiscal years ended in
2000 and 1999, research and development expenses amounted to $.7 million and $.6
million, respectively. Additional research and development funding will be
required for LAAPD arrays and VAPDs if the Company decides to commercialize
these products.

ENVIRONMENTAL REGULATIONS

The photonics industry, similar to the semiconductor industry, is subject to
governmental regulations for the protection of the environment, including those
that relate to air and water quality, solid and hazardous waste handling and the
promotion of occupational safety.

Various federal, state and local laws and regulations require the Company to
maintain certain environmental permits. The Company believes that it has
obtained all necessary environmental permits to conduct its manufacturing.
Changes in the aforementioned federal and state environmental laws and
regulations or enactment or promulgation of new laws and regulations could
require increases in operating costs and delays or interruptions of operations
and may require additional capital expenditures.

BACKLOG AND CUSTOMERS

The Company's sales are made primarily pursuant to standard purchase orders for
delivery of products. However, by industry practice, orders may be canceled or
modified at any time, with the customer being responsible for all finished
goods, all costs, direct and indirect, incurred by the Company and a reasonable
allowance for anticipated profits. No assurance can be given that such amounts
will be received by the Company after cancellation. The Company had
approximately $5 million of backlog at the end of fiscal 2000 compared with a
backlog of approximately $4.5 million at the end of fiscal 1999. The Company
expects that approximately $3.1 million of the backlog orders will be filled in
fiscal year 2001.

The Company currently supplies core business products in support of satellites,
aircraft and ground vehicle missile guidance and tracking systems. Decreases in
military spending have continued to reduce the Company's revenues in these
markets.

The Company also supplies core business products for use in various analytical
and diagnostic medical equipment. The Company's agreement to provide
LED/detector modules to be used in microbiological testing systems resulted



                                       5
<PAGE>   6

in an increase in revenues in the medical segment. Product sales to bioMerieux,
Inc. represent approximately 14% and 8% of the Company's revenues for the fiscal
years ending 2000 and 1999, respectively.

Customers normally purchase the Company's products and incorporate them into
products that they in turn sell in their own markets on an ongoing basis. As a
result, the Company's sales are dependent upon the success of its customers'
products, and its future performance is dependent upon its success in finding
new customers and receiving new orders from existing customers.

MARKETING

The Company markets its products in the United States and Canada through its own
technical sales staff and through independent sales representatives.
International sales, principally Western Europe, are conducted through foreign
distributors (see Note 1 to Consolidated Financial Statements).

In marketing LAAPD products, the Company has recognized that it must compete
with producers of PMTs, which have dominated low light level detection markets
for many years. Even if the Company can establish that its LAAPDs are a
potential alternative to PMTs for certain commercial applications, and assuming
that testing of the LAAPD currently being conducted by OEMs and other third
parties proves successful, the ability to successfully market its LAAPD devices
on a volume basis will be substantially dependent upon the willingness of
potential customers who currently use PMTs to incur the substantial expense and
expend the time and effort necessary for the redesign of their products to
accommodate the LAAPD devices.

COMPETITION

The Company competes with a range of companies for the custom optoelectronic and
silicon photodetector requirements of vendors of medical instruments, computer
peripherals, a variety of industrial products and specialized military and
commercial aerospace applications. The Company believes its principal
competitors for sales of custom devices are small to medium size companies.
Because the Company specializes in custom devices requiring a high degree of
engineering expertise to meet the requirements of specific applications, it
generally does not compete to any significant degree with other large United
States, European or Far Eastern manufacturers of standard "off-the-shelf"
optoelectronic components or silicon photodetectors.

The Company believes that the principal competition for its silicon LAAPD
photodetection devices lies with producers of PMTs, the only product currently
available for many of the applications for which the Company's LAAPD products
are designed. The Company believes that there are a number of manufacturers of
PMTs, most of which have significantly greater financial, technological,
marketing and personnel resources than the Company. In addition, several
companies produce solid state detectors based on small area APD technology.
Although a few additional photodetector companies are engaged in developing
APDs, the Company believes that most of these are limited by their technology to
small area APD devices. The Company believes these small area APDs are
considerably less useful than the Company's LAAPD devices in broadening the
applicability of APD technology to imaging and the sensing of extremely low
light levels. The Company's LAAPD products have electronic signal gain of up to
300 (one photoelectron converted to 300 photoelectrons) while typical small area
APD devices have a gain of about 50 and, therefore, are not competitive with the
Company's LAAPD devices in certain applications.

PMTs were first invented in the 1940's. It is possible that existing PMT
manufacturers or other photodetector manufacturers will begin APD development
and eventually manufacture competitive APD devices.

Other patent submissions are currently under review by the U.S. Patent and
Trademark Office. There can be no assurance that the pending patent applications
will issue as patents, that any issued patents will provide the Company with
significant competitive advantages, or that challenges will not be instituted
against the validity or enforceability of any patent owned by the Company or, if
instituted, that such challenges will not be successful. The cost of litigation
to uphold the validity and prevent infringement of a patent could be
substantial. If the Company is unable to obtain patents for its proposed
applications, other entities may exploit the Company's developments in APD
technology. Furthermore, there can be no assurance the Company's APD technology
will not infringe patents or other rights owned by others, licenses to which may
not be available to the Company. Based on limited patent searches, contacts with
others knowledgeable in the field of APD technology and a review of pertinent
published materials, to the Company's knowledge, its competitors hold no
patents, licenses or other rights to the APD technology which would preclude the
Company from pursuing its intended operations or from obtaining patent
protection for its proposed applications.

In some cases, the Company may rely on trade secrets to protect its innovations.
There can be no assurance that trade secrets will be established, that secrecy
obligations will be honored or that others will not independently develop
similar or superior technology. To the extent that consultants, key employees or
other third parties apply technological information independently developed by
them or by others to Company projects, disputes may arise as to the proprietary
rights to such information which may not be resolved in favor of the Company.

EMPLOYEES

At June 19, 2000, the Company employed 57 full-time employees (including 3
officers), 9 engineering and development personnel, 35 operations personnel
(including 1 officer), 6 sales and marketing personnel, and 7 general
administrative personnel (including 2 officers). The Company may, from time to
time, engage personnel to perform consulting services and to perform research
and development under third party funding. In certain cases, the cost of such
personnel may be included in the direct cost of the contract rather than as
payroll expense.

ITEM 6.   MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

RESULTS OF OPERATIONS

FISCAL YEAR 2000 COMPARED TO FISCAL YEAR 1999

REVENUES

The Company's revenues for the fiscal year ended March 26, 2000 ("2000") were
$6.1 million, a decrease of $1.2 million, or 17%, from revenues of $7.3 million
for the fiscal year ended March 28, 1999 ("1999").

Net product sales made up 100% of the total revenue for 2000. The decrease in
net product sales reflects lower shipments of military aerospace products,
partially offset by higher shipments of commercial products. Volume in military
aerospace products decreased by $1.7 million, or approximately 49% in 2000
compared to 1999. The decrease in military aerospace products was partially
offset by higher shipments of commercial products in the industrial sensing and
medical markets, which increased 28% each in 2000 compared to 1999. During 2000,
shipments of LAAPD products (included in net product sales) rose by 17% over
1999, to $470,000. This level is the highest on record in Company history for
the product line. Sales from LAAPDs represented 8% of total product sales during
2000, as compared to 6% in 1999. The Company anticipates increasing volume from
sales of its proprietary LAAPD products as markets begin to implement newer and
more sophisticated technology.

The Company expects continued increased revenues from the sales of commercial
products in fiscal year 2001. The Company anticipates that net sales in 2001
will exceed what was realized in 2000 and are expected to approximate the sales
levels reached in fiscal 1999.

COSTS AND EXPENSES

Cost of product sales decreased by $180,000 (4%) in 2000 compared to 1999. Cost
of product sales as a percent of net product sales increased by 9% and gross
profit margin on net product sales decreased 9 percentage points to 30% compared
to 1999. Material and labor costs, as a percentage of net sales, remained
constant at 15% and 5%, respectively, for 2000 compared to 1999. Fixed overhead
costs as a percentage of net sales increased to 16% in 2000, from 7% in 1999.
Overall increases in cost of product sales were due to increased overhead rates
resulting from lower overall sales volume. The Company expects gross profit
margin, as a percentage of net sales, to return to approximately the same rate
as was realized in 1999, as sales volume is expected to increase and the Company
does not foresee any notable increases in material or labor costs.

Research and development ("R&D") costs increased by $119,000 (22%) to $671,000
during 2000 compared to 1999. The increase in R&D costs is attributable to
increases in internal R&D efforts as the Company focused on improving its
current line of LAAPD products as well as expanding into new derivatives of the
patented technology. The Company continues development of its next generation
line of LAAPD array products. R&D costs have varied significantly in the past,
and may continue to do so, due to the level of activity associated with
development contracts as well as the number and complexity of new process and
product development projects, the qualification of new process developments and
customer evaluation and acceptance of new products.

Marketing and sales expense increased by $46,000 (5%) to $1,004,000 in 2000. The
increase in marketing and sales expense was due to the recruitment of additional
sales staff, and the resulting increase in sales department salaries, during
2000, which was partially offset by lower commission expenses resulting from
lower sales levels. Marketing and sales expenses are expected to decrease
slightly in 2001 as executive compensation previously reported as marketing and
sales expense is now being reported as administrative expense, due to the
promotion of Brock Koren from Vice President of Sales and Marketing to President
and Chief Executive Officer. The Company has no plans



                                       9
<PAGE>   10

to recruit additional sales staff at the executive level during 2001. However,
the Company intends to pursue its plans for growth and commercialization of the
LAAPD family of products and, as such, expects to incur higher commission
expenses as a result of increased sales in 2001.

General and administrative expenses decreased by $123,000 (12%) to $931,000 in
2000 compared to 1999. The reduction in general and administrative expenses was
the result of a decrease in property tax reserve and general cost cutting
efforts. The company expects a slight increase in general and administrative
expenses in fiscal year 2001, to accommodate anticipated increases in sales and
operating activity.

Interest income in 2000 of $136,000 was $21,000 higher than in 1999. The
increase in interest income is due primarily to increased cash reserves and
higher available interest rates. During Q4 2000, cash reserves increased by $3
million, due to the high volume of stock options exercised.

LIQUIDITY AND CAPITAL RESOURCES

At March 26, 2000, the Company had cash, cash equivalents and short-term
investments of $5.3 million, working capital of $7.4 million and an accumulated
deficit of $17.9 million. The Company's cash, cash equivalents and short-term
investments increased $2.7 million during the twelve months ended March 26,
2000. Cash expenditures were impacted by a reduction of $115,000 in accounts
payable and other accrued expenses. The decrease in accrued expenses was
primarily due to reductions in accrued warranty and other miscellaneous
expenses. Accounts receivable increased by $190,000 in 2000, due to increased
sales in Q4 2000, over the same period in 1999. Capital spending during 2000 was
$134,000 compared to $147,000 during 1999.

To enable the Company to meet its capital commitment needs, the Company has
historically supplemented cash provided by operations with proceeds from private
and public sales of capital stock and borrowings. These funds have been used to
grow the core business and finance the development and initial commercialization
of the Company's LAAPD technology. While the Company believes that initial
commercialization has been completed, it continues development of
proof-of-concept, LAAPD pixelized arrays as well as other derivatives of the
base technology. The continued development of LAAPD arrays beyond the
proof-of-concept phase may require additional funds.

The Company's revolving line of credit agreement with a bank for the lesser of
$1,000,000 or 75 percent of eligible trade accounts receivable, as defined by
the agreement, expired on July 16, 1999. The Company does not foresee a need for
borrowing based upon current projections and, therefore, has elected to forego
the costs for maintaining the line at this time. The Company believes that it
would be most efficient to establish a line when the situation warrants.

The Company is exposed to interest rate risk for marketable securities. At March
26, 2000, the Company had $1,723,000 of short-term investments with a weighted
average interest rate of 6.30%, primarily commercial paper, all of which mature
in fiscal year 2001. The Company also has $246,000 in long-term investments,
with a weighted average interest rate of 6.25%. The long term-investments are
made up of two corporate bond holdings, both of which mature in fiscal year
2002.

The Company believes that the moderate rate of inflation over the past few years
has not had a significant impact on the Company's sales or operating results.

NOTES TO FINANCIAL
STATEMENTS


1.      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        BUSINESS DESCRIPTION - Advanced Photonix, Inc. (the "Company"), is
        engaged in the development and manufacture of optoelectronic
        semiconductor based components, hybrid assemblies and other proprietary
        solid state light and radiation detection devices, including proprietary
        advanced solid state silicon photodetection devices which utilize
        avalanche photodiode ("APD") technology.

        The Company's large area avalanche photodiode ("LAAPD") technology is
        still considered to be a new technology and is subject to risks inherent
        in the development of products based on new technologies. These risks
        include getting the invention out of the laboratory and into actual use
        in the field and stepping up production from the prototype (early)
        stages of manufacturing. In order to fund these development efforts, the
        Company historically has relied upon proceeds from equity financings,
        bank lines-of-credit and loans from stockholders. At March 26, 2000, no
        amounts were outstanding under any bank line-of-credit and there were no
        stockholder loans to the Company.

        RECLASSIFICATIONS - Certain 1999 amounts have been reclassified in order
        to conform with 2000 classifications.

        FISCAL YEAR-END - The Company's fiscal year ends on the last Sunday in
        March. Fiscal years in the two-year period ended March 26, 2000, each
        contain fifty-two weeks.

        OPERATING SEGMENT INFORMATION - The Company predominantly operates in
        one industry segment, light and radiation detection devices.
        Substantially all of the Company's assets and employees are located at
        the Company's headquarters in Camarillo, California.

        In fiscal 2000, the Company had export sales of approximately $992,000
        to customers in North America, Asia, Australia and Europe.

        FAIR VALUE OF FINANCIAL INSTRUMENTS - Based on borrowing rates currently
        available to the Company for bank loans with similar terms and
        maturities, the fair value of the Company's long-term debt approximates
        the carrying value. Furthermore, the carrying value of all other
        financial instruments potentially subject to valuation risk (principally
        consisting of cash equivalents, accounts receivable and accounts
        payable) also approximates fair value.

        CASH AND CASH EQUIVALENTS - The Company considers all highly liquid
        investments, with an original maturity of three months or less when
        purchased, to be cash equivalents.

        SHORT-TERM INVESTMENTS - SFAS No. 115, "Accounting for Certain
        Investments in Debt and Equity Securities", requires that all debt and
        marketable equity securities be classified in one of three categories:
        trading, available-for-sale, or held-to-maturity. It is the Company's
        intent to maintain a liquid portfolio to take advantage of investment
        opportunities; therefore, all of the Company's short-term investments
        are considered to be available-for-sale. The Company has



                                       21
<PAGE>   22

        classified all investments as current assets since it has the intent and
        ability to redeem them within the year.

        Available-for-sale securities are recorded at market value. Unrealized
        holding gains and losses, net of the related income tax effect, on
        available-for-sale securities are excluded from earnings and are
        reported as a separate component of stockholders' equity until realized.
        The amortized cost of debt securities is adjusted for amortization of
        premiums and accretion of discounts to maturity. Such amortization and
        accretion are included in interest income. At the time of sale, any
        realized gains or losses, calculated by the specific identification
        method, are recognized as a component of operating results.

        Short-term investments consist of the following as of March 26, 2000:

        CONCENTRATION OF CREDIT RISK - Financial instruments which potentially
        subject the Company to concentrations of credit risk consist principally
        of cash equivalents, short-term investments and accounts receivable. The
        Company maintains cash balances at a financial institution that is
        insured by the Federal Deposit Insurance Corporation up to $100,000. As
        of March 26, 2000, the Company had cash equivalents at a financial
        institution in excess of Federally insured amounts. The Company invests
        in short-term investments, primarily consisting of corporate commercial
        paper with high-quality companies. Approximately 40% of the Company's
        short-term investments are invested with one company. Accounts
        receivable are unsecured and the Company is at risk to the extent such
        amount becomes uncollectible. The Company performs periodic credit
        evaluations of its customers' financial condition and generally does not
        require collateral. As of March 26, 2000, one customer comprised 37% of
        accounts receivable.

        SIGNIFICANT CUSTOMER - During the fiscal years ended March 26, 2000 and
        March 28, 1999 one customer accounted for 14% and 12%, respectively of
        the Company's net sales.

</TABLE>

        PATENTS - Patents represent costs incurred in connection with patent
        applications. Such costs are amortized using the straight-line method
        over the useful life of the patent once issued, or expensed immediately
        if any specific application is unsuccessful. Amortization expense was
        approximately $4,000 and $3,000 in fiscal 2000 and 1999, respectively.

        GOODWILL - The excess of cost over the purchase price of acquired net
        assets is amortized on a straight-line basis over a 25 year period.
        Amortization expense was $33,000 in fiscal 2000 and 1999. The Company
        continually evaluates the recoverability of goodwill by assessing
        whether the recorded value of the goodwill will be recovered through
        future expected operating results.

        REVENUE RECOGNITION - Revenues from research and development cost
        reimbursement-type contracts are recorded as costs are incurred based
        upon the relationship between actual costs incurred, total estimated
        costs, and the amount of the contract or grant award. Estimation of
        costs are reviewed periodically and any anticipated losses are
        recognized in the period in which they first become determinable.

        The Company uses the unit of delivery method for recognizing sales and
        cost of sales under production contracts. Provision for estimated
        losses, if any, is made in the period in which such losses are
        determined.

        WARRANTIES - The Company typically warrants its products against defects
        in material and workmanship for a period of 90 days from the date of
        shipment. A provision for estimated future warranty costs is recorded
        when products are shipped. To date, warranty costs have not



                                       23

        been material.

        NET INCOME (LOSS) PER SHARE - Net income (loss) per share calculations
        are in accordance with Statement of Financial Accounting Standards
        ("SFAS") No. 128, "Earnings per Share" (SFAS 128). Accordingly, "basic"
        net income (loss) per share is computed by dividing net income (loss) by
        the weighted average number of shares outstanding for each year
        (11,025,000 and 10,916,000 at March 26, 2000 and March 28, 1999,
        respectively). "Diluted" net income (loss) per share has not been
        presented as the impact is anti-dilutive in 2000 and was not material in
        1999.

        RESEARCH AND DEVELOPMENT COSTS - The company charges all research and
        development costs, including costs associated with development contract
        revenues, to expense when incurred. Manufacturing costs associated with
        the development of a new fabrication process or a new product are
        expensed until such times as these processes or products are proven
        through final testing and initial acceptance by the customer. Costs
        related to revenues on non-recurring engineering services billed to
        customers are generally classified as cost of product sales.

        PERVASIVENESS OF ESTIMATES - The preparation of financial statements in
        conformity with generally accepted accounting principles requires
        management to make estimates and assumptions that affect the reported
        amounts of assets and liabilities and disclosure of contingent assets
        and liabilities at the date of the financial statements and the reported
        amounts of revenues and expenses during the reporting period. Actual
        results could differ from those estimates.

        ACCOUNTING FOR STOCK OPTION BASED COMPENSATION - SFAS No. 123,
        "Accounting for Stock Based Compensation" ("SFAS 123"), sets forth
        accounting and reporting standards for stock based employee compensation
        plans. As allowed by SFAS 123, the Company continues to measure
        compensation cost under Accounting Principles Board Opinion No. 25,
        "Accounting for Stock Issued to Employees" (APB 25) and complies with
        the pro forma disclosure requirements of the new standard (see Note 4).

        NEW ACCOUNTING PRONOUNCEMENTS - SFAS No. 130, "Reporting Comprehensive
        Income", establishes standards for reporting and displaying
        comprehensive income and its components in financial statements. The
        Company adopted the provisions of SFAS No. 130 in 1998, but had no
        elements of comprehensive income in 2000 or 1999.

        SFAS No., 131, "Disclosures About Segments of an Enterprise and Related
        Information", establishes a new model for segment reporting, called the
        "management approach" and requires certain disclosures for each segment.
        The Company adopted the provisions of SFAS No. 131 in 1998, but
        currently operates in one industry segment.


2.      CAPITALIZATION

        The Company's Certificate of Incorporation provides for two classes of
        common stock, a Class A for which 50,000,000 shares are authorized for
        issuance and a Class B for which 4,420,113 shares are authorized for
        issuance. The par value of each class is $.001. Subject to certain
        limited exceptions, shares of Class B Common Stock are automatically
        converted into an



                                       24
<PAGE>   25

        equivalent number of Class A shares upon the sale or transfer of the
        Class B Common Stock by the original holder. The holder of each share of
        Class A and Class B Common Stock is entitled to one vote per share.

        The Company has authorized 10,000,000 shares of Preferred Stock, of
        which 780,000 shares have been designated Class A Redeemable Convertible
        Preferred Stock with a par value of $.001 per share. The number of
        shares of Class A Preferred Stock issued and outstanding was 40,000 at
        March 26, 2000. The Class A Preferred Stock has a liquidation preference
        equal to its issue price ($.80 per share). The Class A Preferred Stock
        is convertible at any time, at the option of the holder, into .3 shares
        of Class B Common Stock for each share of Preferred Stock converted. The
        Class A Preferred Stock is subject to redemption at the Company's option
        for $.80 per share at any time. The Company would be required to pay
        approximately $32,000 to redeem these shares. The holders of the Class A
        Preferred Stock are entitled to an annual non-cumulative dividend
        preference of $.072 per share when the Company's net earnings per share
        of Class A Preferred Stock equals or exceeds $.072. The Class A
        Preferred stockholders do not have voting rights except as required by
        applicable law.

3.      INCOME TAXES

        At March 26, 2000, the Company had net operating loss carryforwards of
        approximately $14.6 million for Federal tax purposes that expire at
        various dates through fiscal year 2012. The tax laws related to the
        utilization of loss carryforwards are complex and the amount of the
        Company's loss carryforward that will ultimately be available to offset
        future taxable income may be subject to annual limitations resulting
        from changes in the ownership of the Company's common stock.

        The tax effects of temporary differences that give rise to significant
        portions of the deferred tax assets at March 26, 2000 are substantially
        composed of the Company's net operating loss carryforwards, for which
        the Company has made a full valuation allowance.

        The valuation allowance decreased approximately $284,000 in the year
        ended March 26, 2000, representing primarily net taxable income for tax
        return purposes. In assessing the realizability of deferred tax assets,
        management considers whether it is more likely than not that some
        portion or all of the deferred tax assets will not be realized. The
        ultimate realization of deferred tax assets is dependent upon the
        generation of future taxable income during the periods in which those
        temporary differences become deductible. Management considers the
        scheduled reversal of deferred tax liabilities, projected future taxable
        income and tax planning strategies in making this assessment.

        The tax provision for the years ended March 26, 2000 and March 28, 1999
        are composed of Federal alternative minimum tax and California franchise
        tax.

4.      STOCK OPTIONS

        The Company has three stock option plans: the 1990 Incentive Stock
        Option and Non-Qualified Stock Option Plan, the 1991 Directors' Stock
        Option Plan ("The Directors' Plan") and the 1997 Employee Stock Option
        Plan. The Company measures compensation for these plans under APB
        Opinion No. 25, under which no compensation cost has been recognized.
        Had



                                       25
<PAGE>   26

        compensation expense for these plans been determined consistent with
        SFAS No. 123, the Company's net loss and net loss per share would have
        increased to the following pro forma amounts:


<TABLE>
<CAPTION>
                                                          2000            1999
                                                        ---------       ---------
<S>                                                     <C>             <C>
        Net income (loss), as reported                  $(653,000)      $ 411,000
        Net (loss) - pro forma                          $(956,000)      $ (42,000)
        Basic income (loss) per share, as reported      $   (0.06)      $    0.04
        Basic (loss) per share - pro forma              $   (0.09)      $   (0.00)
</TABLE>

        Because the SFAS No. 123 method of accounting has not been applied to
        options granted prior to April 3, 1995, the resulting pro forma
        compensation cost may not be representative of that to be expected in
        future years. The fair value of each option grant is estimated on the
        date of grant using the Black-Scholes option pricing model with the
        following weighted-average assumptions used for grants in 2000 and 1999,
        respectively: risk-free interest rates of 9.0% and 5.68%, expected
        volatility of 75% and 69% and expected lives of 10 years in both
        periods. No dividends were assumed in the calculations.

        The Company's various stock option plans provide for the granting of
        non-qualified and incentive stock options to purchase up to 2,200,000
        shares of common stock for periods not to exceed 10 years. As of March
        26, 2000, no shares were available for future grant under such plans.
        Options typically vest at the rate of 25% per year over four years,
        except for options granted under The Directors' Plan, which typically
        vest at the rate of 50% per year over two years. Under these plans, the
        option exercise price equals the stock's market price on the date of
        grant. Options may be granted to employees, officers, directors and
        consultants. The Company has also granted options, under similar terms
        as above, under no specific shareholder approved plan.

        Stock option transactions for the years ended March 26, 2000 and March
        28, 1999 are summarized as follows:

Compensation of Directors

In October 1995, the Board of Directors eliminated the accrual or payment of all
fees including all annual fees, meeting fees and any payment for services as the
Chairman or Member of any Committee of the Board of Directors except for
reasonable travel expenses. In March 2000, the Board of Directors voted to
re-establish a directors' fee in the amount of $2,500, payable to each director,
for each meeting attended. The fee is paid to each non-employee director, with
the exception of Hayden Leason, Chairman of the Board, who has voluntarily
waived his fee. In addition, all directors, including employee directors, are
reimbursed for reasonable travel expenses incurred in connection with their
attending meetings of the Board of Directors and committees. Each of the
directors who is not an employee of the Company is eligible for grants of stock
options upon their appointment to the Board of Directors under the 1991 Special
Directors Stock Option Plan and on an annual basis so long as they remain on the
Board. In January 1998, the Board reinstated participation in the 1991 Special
Directors Stock Option Plan, which had also been suspended in October 1995,
other than initial grants for new directors. Directors who are also officers of
the Company or its affiliates do not receive cash compensation in consideration
for their services as directors.
