                                    PART I
 
ITEM 1. BUSINESS
 
 GENERAL
 
  Photon Technology International, Inc. (the "Company" or "PTI(R)"), a New
Jersey based corporation, was organized in November 1983. The Company is
engaged in the research, development, manufacturing, marketing and sales of
proprietary electro-optical and light-based instrumentation, which enable
customers in fields of medical research, health care, environmental science
and industrial process control functions to perform advanced analysis
utilizing fluorescence technologies. It is generally believed that all
substances either fluoresce naturally when "excited" by an intense light
source, or that inert markers or fluorescent "tags" can be introduced which
will "attach" exclusively to the compound to be measured. Utilizing this
fluorescence technology allows for measurement of minute quantities of
compounds. The commercialization of the uses of light started in the early
1970's. During the last decade, photonics, or the use of light as a tool for
research and production purposes, has become a preferred technology for many
applications.
 
  The Company has developed propriety instrumentation products that are used
by companies and organizations in medical life sciences, physical sciences and
environmental and industrial markets to detect minute quantities of compounds
for research, diagnostic testing, monitoring or process/quality control
purposes. The Company has pursued a modular and open architecture strategy,
which it believes is unique for the industry. By developing and manufacturing
a series of systems and a range of electro-optical components, called building
blocks, the Company is able to enhance and rapidly develop specific systems
for new applications.
 
  The Company offers a full product line designed to provide the research and
development community with a single source of supply for their electro-optical
instrumentation and component needs. These systems are designed for and sold
to major private and government research institutions, hospitals and
pharmaceutical companies. The Company has adapted its knowledge and experience
in the field of fluorescence technology to commercial applications which
address a broad array of needs and markets.
 
  In June 1987, the Company incorporated a wholly-owned subsidiary, Photon
Technology International (Canada) Inc., located in London, Ontario, Canada
(the "Canadian Subsidiary"). The Canadian Subsidiary's operations include
manufacturing, research and development, engineering and product support
activities. This Canadian plant site continues to be the primary manufacturing
source for the Company.
 
  The Company maintains a sales office in London, England responsible for
sales, service and distribution support in Continental Europe and the former
Eastern Bloc Countries. The Company has appointed several distributors to
support its activities in Europe. These distributors are managed by the London
office. In September 1994, the Company established a subsidiary PhotoMed GmbH,
a German subsidiary (the "German Subsidiary"). The German Subsidiary operates
as a sales and service office to handle Germany, Austria, Finland and the
Scandinavian countries. The German Subsidiary is strategically important to
the Company's overall market penetration, expansion of sales coverage and
sales growth in Europe. In combination with the Company's branch office in the
United Kingdom, the German Subsidiary strengthened direct sales and service
coverage in two of the three major country markets in Europe.
 
  In March 1990, the Company entered into a joint venture with M.L. Technology
Ventures, L.P. ("MLTV"), whereby the joint venture would manufacture and
market some or all of the products developed pursuant to a research and
development agreement between the Company and MLTV. The research agreement was
entered into in April 1987 to develop four different instruments for
fluorescence applications. On December 8, 1995, the Company entered into an
agreement with MLTV whereby the Company issued 1,000,000 shares of common
stock for payment of the technology developed under the joint venture between
the Company and MLTV, and MLTV's joint venture interest (the "December 1995
MLTV Agreement"). The December 1995 MLTV Agreement terminated the joint
venture. The 1,000,000 shares of common stock was in full settlement of the
$627,000 base purchase price option for the technology in addition to
royalties for a five year period.
 
                                       2
<PAGE>
 
The common shares were recorded at market value (bid price) of .875 per share
or $875,000, and this value is recorded in "Paid-in-Capital". The purchase of
the technology represents an intangible asset of $875,000 which was recorded
as an "Other Asset" and will be amortized on a straight-line basis over a five
(5) year period. As of June 30, 1996, $42,000 has been amortized and the
balance represents $833,000.
 
  All four technologies associated with the MLTV joint venture have been
developed. The Company is committed to manufacture and market these products.
The Company completed a prototype of the fourth instrument known as DeltaRam,
and has started a limited first production run. Full commercialization of this
product has been limited due to a need for more available financial resources.
It is the Company's intention to introduce and sell this product into its
markets in fiscal 1997. (See "BUSINESS--Research and Development").
 
  The Company's integrated product line encompasses three major product
groups, (i) subcomponents, such as mirrors, power supplies, lamps and
gratings; (ii) components, such as monochromators, light sources; and
(iii) advanced systems which incorporate the subcomponents and components made
available by the Company and others. These products perform four basic
applications which cover the full range of functions provided by electro-
optical and light-based instrumentation:
 
  (a) The "generation" of light through the use of power supplies and lamps;
 
  (b) The "handling" and directing of light through the use of
      monochromators, sample compartments, gratings, choppers and lenses;
 
  (c) The "detection" of light sensitive elements and other matter through
      the use of photomultipliers, silicon detectors, and cameras; and
 
  (d) The "analysis" and handling of data through the use of computer
      software and hardware.
 
  These functions are fundamental to advancing light-based technology for the
commercial and scientific utilization of light by the research and development
community and within manufacturing processes.
 
  Light has important uses in the pharmaceutical industry for the development,
characterization and production of new drugs. In the energy industry light is
necessary for the enhancement of the efficiency of fuels and development of
new sources of energy and in the communications industry light provides more
efficient transportation of information. In the semiconductor industry light
is used for the production of better quality chips and yields. Light is also
used in the computer industry for better storage and in medicine, for safer
diagnostics through the replacement of more harmful techniques employing
radioactive compounds and X-rays.
 
  The Company believes that light-based instrumentation can offer a more
accurate, sensitive, safer and less costly alternative to previously used
methods. The fluorescence technology measures minute sub-cellular substances
and generally has replaced radioactive analysis in detecting various amino
acids. A number of fluorescent dyes and/or tags have been developed primarily
for use in the detection of calcium ions in living cells. This information is
essential to the understanding of how and why various diseases and drugs
affect the body's intracellular transport system. Such measurements can play
an important role in the life sciences with many new and developing
applications.
 
  The Company has the ability to identify commercial and scientific
applications and, through its technical and design capability, to provide
products which "add value" to the end users and which are responsive to these
needs. This ability is integral to the Company's success. The Company's know-
how which is employed in its design and assembly techniques results in a
competitive product which has high precision, quality and lower costs.
 
 INDUSTRY
 
  The Company operates in what can be broadly defined as the photonics
industry. The photonics industry utilizes light for application in medical
research and testing, pharmaceutical drug development, industrial process
 
                                       3
<PAGE>
 
and quality control, and environmental, research monitoring and control. It is
a relatively new industry, having only emerged in the 1970s.
 
  Light-based instrumentation for industry, medicine, and research is a multi-
billion dollar business. As a result, applications for photonics
instrumentation and techniques for medicine is still emerging. The Company's
industry niche utilizes fluorescence technology to measure samples in small
amounts or quantities, track movement/location, monitor chemical or physical
changes and identify or isolate the sample from surrounding environment. In
medical research applications and drug development, this can be accomplished
without harm or destruction to the sample (i.e. cells). In all applications
the speed, sensitivity and light reaction are important for process, and
quality control, and monitoring.
 
 TECHNOLOGY
 
  The application of light in the fields of industry, medicine, and research
falls into many broad categories. Among these is a phenomenon called
"fluorescence." It is this phenomenon that PTI's instruments are designed to
create and measure.
 
  When light strikes a substance, the light is absorbed and then re-emitted.
If the wavelength of light that is re-emitted is different from that which is
absorbed, then the substance is said to have fluoresced. By stimulating
fluorescence and monitoring its location and intensity, scientists can
identify the concentration and changes of substances. While not all substances
fluoresce, it is possible to create a dye (also called a probe) that will
cause non-fluorescent substances to fluoresce.
 
  While the phenomenon of fluorescence is certainly not new, applications for
the technique are new and emerging. The recent development of fluorescent dyes
has made fluorescence the most exciting tool today. Practical applications for
new dyes and assays are being discovered almost on a daily basis. Fluorescence
is now a multi-billion dollar industry.
 
  Fluorescence is such a powerful and rapidly expanding tool for cellular and
sub-cellular testing because it is:
 
  .  MORE SENSITIVE than other means of detection (about a factor of
     1,000,000 times more) which means that very small, sub-cellular amounts
     of substances can be detected and measured with great accuracy.
 
  .  SAFER than other means of detection, because it is non-invasive (does
     not physically injure the cell) and non-radioactive (avoids health and
     disposal problems).
 
  .  FASTER than other means--it can monitor changes in trillionths of a
     second, or about 1,000,000 times faster than other techniques.
 
  .  A VISUAL PROCESS--microscopic images can be gathered and displayed, for
     example, showing changes inside living cells.
 
  .  LESS EXPENSIVE than other techniques, which means it can do more work
     for less money, while saving time, resources and even lives.
 
 PRODUCTS
 
  The Company's product strategy is to offer a modular product line,
consisting of subcomponents, components and systems, in an open architecture
design format for the marketplace through providing light generating, light
handling, detection and analysis products. The instruments are designed and
offered as compatible components, often referred to as optical building
blocks. Through this open architecture, the Company is able to rapidly respond
to consumer demand by adding or upgrading components, or introducing new
systems. This marketing strategy minimizes product obsolescence, increases the
versatility of its product line, and provides cost-effective and competitive
pricing. The Company has sold over 700 systems in over 35 countries, with
about 60% of systems sales in North America. The Company's product line of
systems and
 
                                       4
<PAGE>
 
building blocks is represented in a number of the most significant research
institutions, research hospitals, laboratories, pharmaceutical companies and
major industrial corporations on a worldwide basis.
 
  The Company has five product groups:
 
  SUBCOMPONENTS
 
  The subcomponents offered by the Company are either incorporated into
finished products that are then sold directly to end-users or are sold to
original equipment manufacturers ("O.E.M.'s"). Many of these subcomponents are
designed and produced by the Company. However, for standard industry needs,
the Company maintains an inventory of subcomponents purchased from
distributors and wholesalers for use by the Company in its systems or for sale
to O.E.M.'s. The subcomponents that are purchased by the Company include
lamps, gratings, photomultiplier tubes, fiber optics, lenses, diffusers,
filters, mirrors, and other component accessories.
 
  The subcomponents that are manufactured, assembled or sub-contracted by the
Company include, among other things, certain key optical components and
machined subassemblies. These subcomponents are primarily designed for and
sold to customers in the industrial and military markets and are used to
collect, focus and direct light. The Company's key optical elements are not
made from glass but rather are machined from aluminum, copper, brass or
stainless steel using technology developed by the Company to eliminate the
expense and fragility associated with traditional glass.
 
  COMPONENTS--OPTICAL BUILDING BLOCKS
 
  The Company's components are distinct products comprised of subcomponents
and subassemblies. Typically, the components are combined by the Company or
its customers to form systems. The Company designs and assembles a variety of
components which are light source, handling, detection and analysis products.
 
  There is a wide range of customers for light source components. Light
sources are required for virtually all light-generating equipment and also
have a variety of uses in the electro-optical industry. Light source equipment
marketed by the Company includes, among other things, high intensity arc
lamps, regulated power supplies, modulators, optical feedback modules,
microscope illuminators, nitrogen and dye lasers, pulsed nanosecond flash
lamps and pulsed xenon strobe lamps.
 
  There are many commercial and scientific uses for light-handling
instruments. Certain of these instruments separate light into timed, pulsed
segments. Other instruments break up light into different wavelengths. The
Company offers a variety of light-handling components such as optical
choppers, monochromators, sample holders and sample compartments.
 
  Light detection components function as process monitors in the production
and quality control applications. These components include such diverse
products as video cameras, photodiodes and photomultipliers. Currently, the
Company designs and assembles photomultipliers which are generally used in
conjunction with other Company components and systems.
 
  Light analysis components are used in a variety of equipment utilized in the
field of electronics and in computer hardware. With respect to computers, the
Company's light analysis components convert signals generated by a detector
into meaningful information that can be displayed on a monitor.
 
  These components are used in every light-related application. For this
reason, the market for such products is very diverse. The Company manufactures
an extensive line of fluorescence instrumentation. The line is further
enhanced by its software which provides the Company with state-of-the-art and
proprietary software for its systems. The Company has a competitive advantage
of making a wide variety of compatible components that are also state-of-the-
art in specifications and competitive in price. The Company is upgrading and
expanding its products to help maintain its competitive advantage.

  SYSTEMS--RATIOMASTER(TM) PRODUCT GROUP
 
  Since 1987, the Company has developed and manufactured ratio fluorescence
and general fluorescence systems. The Company's first system line, the
patented Deltascan(TM) ratio fluorescence instrument, was assembled from
original optical building blocks. The Company believes that it is one of the
few designers and manufacturers of electro-optical instruments that are fully-
automated systems based on the building-block approach. These systems are
future-ready through a modular and open architecture design approach, which
easily accommodates change and stand in sharp contrast to conventional
instrument design. Most competitors' systems are integrated, or closed
architecture.
 
  The RatioMaster(TM) Product Group includes the Deltascan(TM) and other
systems designed for applications using radiometric fluorescent probes to
track location, concentration, and movement in measurement of intracellular
ionic calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), and pH and
other intracellular ions in cell suspension, tissues, single cells or adherent
cells. The three RatioMaster sub-groups, based on dye of measurement, are:
 
  (1) Macro-systems which are sample compartment and cuvette-based for
      measuring suspensions, tissues and solids for cell population studies.
 
  (2) Micro-systems which are microscope-based for measuring on the cellular
      and sub-cellular level for singular cell studies.
 
  (3) Imaging-systems for photographic-like studies of cells, which allows
      quantitative ratio fluorescence as a method to spatially resolve
      intracellular ion activity within the cell. These changes in
      intracellular ion concentration can be observed both directly and much
      more efficiently than with the human eye, and the field of view
      embraces a number of cells. The imaging system can be sold as an add-on
      to an existing illuminated inverted fluorescence microscope, as a an
      independent system, or added to the Micro systems.
 
  This RatioMaster(TM) product group includes the following light sources:
 
  PowerArc(TM) provides a xenon lamp illumination source for applications
involving only emission-shifted probes.
 
  PowerFilter(TM) high speed dual wavelength scanning illuminator for
applications using excitation-shifted probes. This unique light source
provides the best speed criteria without requiring a fluorescence excitation
spectra.
 
  DeltaRam(TM) revolutionary high-speed multi-wavelength illuminator using a
proprietary and patented optical configuration and technique.
 
  Deltascan(TM) high speed dual scanning illuminator using the patented, fast,
computer controlled alternating dual scanning monochromators for applications.
 
  Through the products' open architecture, the customer or user can
economically enhance each system and add capabilities present in the other
sub-groups to their existing purchased system, or in a configuration which
crosses over sub-groups to meet new system requirements.
 
  SYSTEMS--QUANTAMASTER(TM) PRODUCT GROUP
 
  The Company's new and expanded system line, the QuantaMaster(TM) group, is
used primarily to study substances that naturally fluoresce. Fluorescent dyes
are used as well, but they are different from those used with RatioMaster(TM)
systems. This technology of steady state products is proprietary to the
Company. The major advantage of fluorescence as a measurement technique is its
sensitivity, which provides a competitive advantage. Additional system options
and accessories are still being developed to round out this product line.
 
                                       6
<PAGE>
 
  The QuantaMaster(TM) series of luminescence spectrometers was developed for
routine measurement of steady state fluorescence, phosphorescence,
chemiluminescence and bioluminescence. Steady state fluorescence is the
foundation of the fluorescence laboratory to meet the requirements for
excitation and emission scans, time-based experiments, and synchronous scans.
Steady state fluorescence measurements are used to detect the amount or change
in the amount of a substance. With the superior sensitivity of this technique,
a fast measurement can detect a lower concentration of the fluorescing
species, or small changes in a sample.
 
  This product group has the same modular and open architecture profile as the
RatioMaster(TM) product group and as a result can be enhanced and expanded for
capabilities.
 
  SYSTEMS--TIMEMASTER(TM) PRODUCT GROUP
 
  TimeMaster(TM) systems are used to determine fluorescence lifetimes, a
technique used to distinguish between similar substances. The fluorescence
lifetime represents the average time that a molecule spends in an excited
state before emitting a photon and returning to the ground state. It is an
important and unique feature of an excited state. Fluorescence lifetimes are
very short. Most fluorescence lifetimes fall within the range of hundreds of
picoseconds to hundreds of nanoseconds. The fluorescence lifetime can function
as a molecular stopwatch to observe a variety of interesting molecular events.
An antibody may rotate slightly within its molecular environment. A protein
can change orientation. A critical binding reaction may occur. Because the
time-scale of these events is similar to the fluorescence lifetime, the
measurement of the fluorescence lifetime allows the researcher to peer into
the molecule and observe these phenomena.
 
  In late fiscal 1994, the Company introduced a revolutionary newly patented
design, and the most economical systems for fluorescence lifetime
measurements, the TimeMaster(TM) fluorescence Lifetime Spectrometers.
These systems revolutionized the fluorescence lifetime techniques by designing
easy-to-use systems which are consistent with the Company's modular and open
architecture strategy for products. Research and development efforts by the
Company during fiscal 1994 and 1995 provided a product line with a unique
strobe technique, a choice of two different lifetime techniques and three
different base system configurations as follows:
 
  StrobeMaster(TM) provides a unique and patented strobe technique for
measuring fluorescence lifetimes which is economical to use. The strobe
technique is intensity dependent and provides accurate measurements at very
high speeds. These characteristics of the strobe technique are very important
in the life sciences area, where samples are not stable over long periods of
time. The StrobeMaster(TM) uses a NanoFlash(TM) illuminator source.
 
  LaserStrobe(TM) is based on the strobe technique for measuring fluorescence
lifetimes and is as unique as the StrobeMaster(TM). With a nitrogen/dye laser
illumination source, the strobe technique provides for measurements of
lifetimes with a precision of below one nanosecond.
 
  The unique strobe technique, through the introduction and sales of the
StrobeMaster(TM) and LaserStrobe(TM), has started to be recognized and
accepted for measuring fluorescence lifetimes as evident by sales of these
systems during fiscal 1996.
 
 SALES AND MARKETING
 
  The Company's sales are primarily for research and development of analytical
measurement applications. The Company will continue to focus on opportunistic
areas in both life sciences and physical sciences areas because of the
diversity of the markets and different user demands.
 
  Buying decisions for the Company's products are generally made by
professionals in corporations, universities, government or private labs and
hospitals. These individuals usually belong to professional organizations,
read and receive professional journals and attend trade conferences and
seminars. Papers that have been published which discuss the Company's
equipment in the research process represent a significant influence on the
peers and affiliated groups of such professionals and their industries. Such
papers are an important marketing tool for the Company.
 
                                       7
<PAGE>
 
  In addition to private industry, universities and hospitals, a significant
source of the Company's sales comes from government supported purchases
(except in the U.S. where health care is privatized). The major market for
fluorescence instrumentation is still limited to the developed nations. The
U.S. and Canada are by far the largest markets estimated at 30% of the total
world market. This is followed by Europe, which is roughly equivalent to the
U.S. market size. The Japanese market is around 15% and has local competition
that is successful only in this market area. The remainder of the world
accounts for less than 25%.
 
  The Company enjoys an excellent reputation with its customer base. There
have been numerous multiple-system sales to the same customers, and most of
these systems have been the more expensive "top-of-the-line" models. The
Company has recently introduced its lower-priced systems lines to be
competitive in the mid-market range for both ratio-fluorescence and general
fluorescence. The Company's objective is to create a higher profile and to
become better known in the marketplace.
 
  Although the Company is focused on selling its systems lines, the Company
will continue to sell the Optical Building Block ("OBB") products (i.e., arc
lamps, regulated power supplies, microscope illuminators, nitrogen and dye
lasers, nanosecond flash lamps, pulsed xenon strobe lamps, choppers,
monochromators, sample compartments, photomultipliers, etc.) as they provide a
good source of income. Although the market for OBBs is large, the Company will
regard this product line as secondary to its system lines from a strategic
point of view.
 
  The Company's promotional activities to penetrate the various markets, both
domestically and internationally, take the form of trade shows, direct mail,
research seminars, symposiums and advertising in periodicals. In North
America, sales are handled by direct sales personnel located in Monmouth
Junction, New Jersey; Ashland, Massachusetts; Algonquin, Illinois; McKinney,
Texas; Cary, North Carolina; Indianapolis; Indiana and London, Ontario,
Canada. In Continental Europe, including the former Eastern Bloc countries,
sales responsibilities are shared by the Company's branch office in London,
England, independent distributors PhotoMed GmbH, a wholly owned subsidiary,
and the sales office in Oslo, Norway. Independent distributors and/or agents
service the Far East and other foreign markets.
 
 COMPETITION
 
  The market for the Company's products is highly competitive, and PTI expects
this competition to increase. Many of the Company's competitors have
significantly greater research and development, marketing and financial
resources than the Company, and therefore represent significant competition.
As with all new and emerging markets, there are no dominant players in the
fluorescent instrumentation marketplace (greater than 10% market share). There
are many small companies, many of which companies smaller than PTI. The
Company believes that the primary competitive factors in the market for the
Company's products are product performance, price, breadth of product
offerings and technical support.
 
  With respect to its sub-component and component product lines, the Company
competes with catalog distributors that sell standard items and companies that
manufacture a limited range of competitive sub-components and components.
 
  The Company's systems compete with fluorescence instruments offered by large
corporations such as Perkin Elmer, Hitachi, Kontron, Jasco and Shimadzu. These
corporations have a much higher market profile and significantly greater
marketing and financial resources, with the capacity to offer products at a
lower price. In addition, many other small companies have attempted to enter
the fluorescence market, including SLM, IBH, SPEX, Edinburgh, ISS and
Universal Imaging.

no practical recourse.
 
 RESEARCH AND DEVELOPMENT
 
  The Company believes that it is important to continue to fund research and
development of new commercial applications utilizing the base technology of
photonics with a focus on ratio and general fluorescence. The Company plans to
also place its energies toward improvements to existing products to reduce
costs and to promote and maintain competitive advantages. Over the past five
(5) years, the Company's spending on research and development for new products
and systems, has been limited due to financial resources. The Company's short-
term strategy has been to repackage and enhance its existing systems and to
promote the "value added" concept of the Company's full line of ratio
fluorescence and general fluorescence products, while working within its
available financial resources.
 
  During fiscal 1995, New Jersey based research and development personnel were
directed and focused on software development which led to the introduction in
April 1995 of FeliX software for ratio and general fluorescence applications.
This software product sold as an integral part of all fluorescence systems.
This software product was written under the Microsoft Windows platform and a
universal program language which allows versatility and ease of product
enhancements for interfacing other software products, adding features and
overall increased functionality. A portion of this software development was
capitalized in accordance with accounting guidelines (See Note J--Notes to
Consolidated Financial Statements). The Canadian research and development team
focused on continued system instrumentation development for the TimeMaster(TM)
fluorescence spectrometer line and the proprietary strobe technique, including
software development. The TimeMaster(TM) was introduced and first shipped in
January 1994. Other engineering projects were directed at cost reduction of
components.
 
  During fiscal 1996, New Jersey based research and development continued to
focus heavily on developing new software products, and modules to add to core
software programs to increase scope and functionality of product systems.
Additionally, the Company increased its hardware development support and
efforts which resulted in the completion of the DeltaRam(TM) prototype, a
revolutionary monochromator which will provide a high speed multi-
wavelength(TM) illumination, and the IC100(TM), an intensified CCD camera, a
low price and very competitive product which provided incremental sales as a
"pull" product for the Company's ImageMaster(TM) product line and as a stand
alone product for varied customer applications. The Canadian research and
development team continued development on system instrumentation for the
TimeMaster(TM) fluorescence spectrometer line to improve component integration
and lower costs, developed a new higher performance and lower cost
photomultiplier housing to be introduced in early fiscal 1997, and began
development of a "state of the art" microprocessor hardware control unit. The
major focus of the Canadian team was cost reduction, integration and update of
component products. In addition to the research and development conducted by
employees of the Company, the Company intends to continue its practice of
utilizing researchers at academic centers of excellence to perform research in
their areas of specialization and outside contract development support of
specific projects. The Company has engaged Dr. Martin Poenie from the
University of Texas for the development of a proprietary product.
 
  Software and hardware development and support will continue in fiscal 1997
for new and targeted existing product lines. In addition to the research and
development conducted by employees of the Company, the Company intends to
continue its practice of utilizing researchers at academic centers of
excellence to perform research in their areas of specialization, and outside
contract development support for specific projects.
 
  On December 8, 1995 the Company reached an agreement with MLTV for the
purchase of the technology and MLTV's joint venture interest (See "BUSINESS--
General"). The final product started under the Company's agreement with MLTV
has been completed. The products completed and manufactured are the
 
                                       9
<PAGE>
 
photometer, microscope illuminator, ImageMaster(TM), DeltaRam(TM), and a
variety of components. The reported sales include the above mentioned products
with exception of the DeltaRam(TM) and several subcomponents of the products
which were funded through the research and development agreement.
 
  In May 1991, the Company entered into a note and warrant purchase agreement
(the "Note Agreement") with MLTV. Pursuant to the Note Agreement, the Company
borrowed from MLTV the principal amount of $500,000, which is subordinated to
all other indebtedness of the Company, including vendor payments.
The subordinated loan was due and payable on May 7, 1994. Interest, at a rate
of 13% per annum, which was due and payable under the subordinated loan
schedule, had been accrued in the amount of $196,000, and added to the
principal by agreement between MLTV and the Company. In fiscal 1993 there was
an additional fee added to the principal amount owing of $75,000 which was
associated with the deferral of interest payments at that time. In
consideration of this loan, the Company issued warrants for 25,000 shares of
Common Stock with an exercise price of $2.00 per share and reduced the price
on all existing warrants held by MLTV representing 500,000 shares of Common
Stock from $3.50 to $2.00 per share. These warrants expired on April 6, 1994.
The full debt of $771,000 has not been paid to date. Since expiration of the
May 7, 1994 due date, MLTV has continued to extend the payment due date and in
an agreement dated September 9, 1994 extended the full debt until October 1,
1995 and without incremental fees and/or interest. This agreement on MLTV's
part was in consideration of the Company's performance and continued progress
in the Company's efforts to raise additional funding. The December 1995 MLTV
Agreement provided for the repayment of the debt. Pursuant to the December
1995 Agreement, the Company agreed to pay the principle amount of $20,000 a
month for a twenty-four (24) month period for a total of $480,000. the balance
of $291,000 is to be paid at the end of the twenty-four (24) month term. As of
June 30, 1996, the Company has paid $140,000 and reduced the total outstanding
balance to $631,000.
 
 BACKLOG
 
  The Company's backlog consists of orders scheduled for delivery within three
months. As of June 30, 1996, the Company backlog was $1,087,000, as compared
with $1,516,000 as of June 30, 1995.
 
 MANUFACTURING, RAW MATERIALS AND SUPPLIERS
 
  Manufacturing of the Company's products involves optical, mechanical and
electronics assembly, including product component and product systems testing
to specifications, in order to provide quality control and quality assurance.
Some of the process manufacturing requires machining and manufacturing of
electronics and optical components.
 
  The Company's manufacturing operations are located within a total of 18,000
square feet which includes production capabilities in two North American
plants. The primary production operation is located in the plant at London,
Ontario, Canada. The secondary production operation is located at the
Corporate headquarters in South Brunswick, New Jersey. These operations
provide the Company the opportunity to produce products-systems, components
and subcomponents where production resources are most economical.
 
  The Company's production network includes sourcing of material, components
and/or subcomponents from outside vendors. There are several "key" outside
vendors for specialty manufacturing and sourcing of optical components. There
are some materials, optics and electronics components, that are "sole" sourced
by the Company. In certain cases, subcontractors are used for machining and
tooling, thereby reducing the need for capital expenditures.
 
  Overall, the supply of materials, components, subcomponents and
subcontracted services have been reliable and consistent. The Company's
reliance on a sole or limited sourcing from some outside supply or service
vendors does present several risks including an inability to obtain an
adequate supply, to negotiate the lowest price and to sustain timely
deliveries of components or services. The Company will continue its efforts to
 
                                      10
<PAGE>
 
negotiate more blanket orders to protect its supply chain and to lower costs.
In the area of sole sourced materials and/or components, the Company will
continue its efforts to identify and engage secondary suppliers and to
consider capital equipment purchases in order to manufacture within the
Company's operations.
 
 RECENT DEVELOPMENTS
 
  Reverse Stock Split
 
  On June 21, 1996, the Company amended its Restated and Amended Certificate
of Incorporation to reflect a reverse split on all authorized common shares of
the Company's common stock and options for common shares of common stock in
the form of one (1) common share for every three (3) common shares (the
"Reverse Split"). As a result of the Reverse Split the total number of
outstanding shares of the Company's common stock was reduced from 3,461,328
shares of common stock to 1,153,776 shares of common stock. The stock
continues to trade on the OTC Bulletin Board at this time.
 
  Loan
 
  On July 26, 1996, the Company entered into a $2,000,000 secured working
capital line of credit with Silicon Valley Bank of California ("Silicon
Valley"). The Company used proceeds from the Silicon Valley line of credit to
pay off the outstanding $1,300,000 credit facility with the Bank of Montreal.
The Silicon Valley line of credit is subject to monthly interest payments at
the rate of prime plus 1.5%. The balance of the loan is due at maturity on
July 1, 1997. The Company intends to use the balance of the Silicon Valley
line of credit to support working capital requirements.
 
  Distribution Agreement
 
  On August 15, 1996, PhotoMed GmbH entered into an agreement to become the
exclusive distributor for Omega Optical/USA for the European Community ("EC")
territories of Germany and Austria. This agreement will provide incremental
products and business for the PhotoMed GmbH sales operation. Omega Optical
products and components are complements to the Company's product lines which
are sold into the same markets and customer base. This business relationship
should provide a source of leads for the Company's system product lines in
addition to incremental sales of Omega products.
 
 HUMAN RESOURCES
 
  As of fiscal year ended June 30, 1996, the Company has 62 full-time
employees, 27 of whom are employed in the United States, 24 of whom are
employed by the Canadian Subsidiary in London, Ontario, Canada, 5 of whom are
employed in the London, England sales office and 6 of whom are employed in the
Wedel, Germany sales/service office. The total employees consist of 22 in
manufacturing/operations, 27 in sales and marketing, 8 in product development
and 5 in administration. None of the Company's employees are covered by
collective bargaining agreements. The Company's success will depend in part on
its continued ability to attract and retain high quality employees. The
Company considers its relations with employees to be good.
 
ITEM 2.  PROPERTIES
 
  The Company leases a total of approximately 18,000 square feet in
manufacturing, administrative, sales and research and development office space

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATION
 
 RESULTS OF OPERATIONS
 
  FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995
 
  Net sales of $9,190,000 in 1996 increased $1,398,000 or 17.9% from
$7,792,000 in 1995. This real growth increase in net sales represented the
continued strength of ratio fluorescence sales on a worldwide basis for
existing products.
 
  Total revenue of $9,259,000 in 1996 increased $1,411,000 in 18.0% from
$7,848,000 in 1995. This change primarily related to increased net sales. The
other income component of total revenue increased $12,000 or 22.1% from
$56,000 in 1995 to $68,000 in 1996, primarily due to rental income on sub-
leased space in the German Subsidiary.
 
  Cost of products sold of $3,656,000 for 1996 increased in dollar terms by
$334,000 or 10.0% in comparison to cost of sales of $3,322,000 in 1995. On a
percentage of net sales basis, cost of products sold decreased from 42.6% to
39.8% for the same comparative periods. The dollar cost increase in cost of
sales related to the increased sales volume. The decrease as a percentage of
net sales in comparison to the prior year reflected (a) a volume-mix impact of
international sales with higher gross margins (b) the impact of component
material cost reductions through re-engineering of specific products (c) the
impact of adding machining capacity with provided incremental production for
some components previously manufactured outside (d) fuller absorption of
overhead costs due to higher production volume throughout to support increased
sales volume.
 
  Selling, general and administrative expenses of $4,126,000 in 1996 increased
$951,000 or 30.0% over $3,175,000 in 1995. This increase reflected (a) the
impact of higher sales volume on variable selling related expenses (b) the
level of international agent commission due to a volume-mix shift from direct
sales to agent sales (c) incremental sales personnel to expand sales territory
coverage worldwide (d) the full year expense effect of the German Subsidiary
sales operation (e) incremental administrative expenses related to financing
activities and support for the German Subsidiary operations for a full year.
On a percentage of sales basis, selling, general and administrative expenses
increased from 40.8% in 1995 to 44.9% in 1996. This increase was primarily due
to the necessary and incremental fixed level of investment in sales and
marketing and higher administrative costs, which were not fully leveraged by
the sales volume increase year to year.
 
  Research and development expenditures of $844,000 or 9.2% of net sales in
1996, increased from $571,000 or 7.3% of net sales in 1995, an increase of
$274,000 or 48.0%. The increase in these expenses reflected the Company's
continued commitment to research and development expenses and was primarily
due to increased personnel for both software and hardware development, and
increased contract engineering support in Germany to satisfy the requirements
of certifying the Company's products for sales into the EC in accordance with
regulatory guidelines. These expenses are net of software expense
capitalization of $250,000 in 1996 in comparison to $255,000 in 1995. Active
research and development expenditures, including software expenses
capitalized, was $1.1 million or 11.9% of sales in 1996 in comparison to
$826,000 or 10.6% in 1995 on the
 
                                      14
<PAGE>
 
same basis. Research and development activities were heavily focused on new
product development--hardware and software, and cost reduction. The Company's
goal is to target at least 10% of its net sales for this strategic area and
will continue to allocate financial resources to the best extent possible
while seeking additional financial resources in order to increase investment.
 
  Interest expenses increased by $158,000 or 130% from $122,000 in 1995 to
$280,000 in 1996. This increase primarily relates to interest on incremental
short term borrowings on the credit facilities with the Company's lenders and
interest payments related to the 12% subordinated debt issue with Covington
Capital Corporation as part of a financing agreement.
 
  Depreciation and amortization increased from $148,000 in 1995 to $150,000 in
1996. New equipment purchased and related depreciation was mostly offset by
lower amortization on equipment under capital lease pursuant to the sale-
leaseback agreement for lab equipment, which was purchased for one (1) dollar
in the fourth quarter of fiscal year 1996.
 
  Goodwill amortization increased by $47,000 or 44.7% from $106,000 in 1995 to
$153,000 in 1996. This increase represents the full year incremental effect of
the formation and capitalized start-up expenses of the German Subsidiary in
September 1994 in fiscal 1995. The total amount of goodwill represents
$801,000 and is amortized using a straight line method over five (5) years.
The balance of goodwill recorded in "other assets" at June 30, 1996 was
$542,000. Foreign exchange gain of $34,000 in 1996 was lower in comparison to
the $81,000 foreign exchange gain in 1995. Foreign exchange gain and losses
are primarily related to the level of cash transactions denominated in foreign
currency and the fluctuation of foreign currency in comparison to the
U.S. dollar. The lower exchange in this fiscal year, in comparison to the
prior year, relates to lower cash transactional activity overall and a non-
repetitive single bank transaction involving a re-financing between Midlantic
National and Bank of Montreal in fiscal 1995.
 
  Deferred tax benefit of $63,000 in 1996 represents a partial reversal of a
deferred tax expense recorded in 1995. Deferred taxes arise from a temporary
difference between book and tax income, as a result of the capitalization of
the excess of liabilities over acquired assets. In 1995 this deferred tax
expense related to the formation and start-up of the German Subsidiary, which
at that time was 51% owned and fully controlled by the Company. In 1996, this
deferred tax was reversed due to an increase in the net deferred tax asset
(reduction of valuation allowance) related to Canadian net operation loss
carryforwards from prior years, which based on past experience, will have
greater than a fifty percent probability of being realized. (See Note F).
 
  In fiscal 1995 the Company recorded minority interest of $42,000 as an
adjustment to consolidated income of the Company in order to exclude the 49%
minority ownership position of the shareholders of German Subsidiary. In this
fiscal year 1996, on July 5, 1995, the Company acquired the remaining 49% of
the German Subsidiary for 150,000 shares of treasure stock a value of $1.00
per common share or $150,000. As a result of this transaction, German
Subsidiary became a wholly-owned subsidiary of the Company and there was no
longer any adjustments or exclusions to income for minority interest.
 
  As a result of the foregoing, the Company reported net income for fiscal
1996 of $146,000 in comparison to net income of $357,000, a decrease of
$212,000 or 59.3% from the prior year.
 
  As a result of this net income performance, earnings per share based on
weighted average number of common shares outstanding was fourteen cents
($0.14) in comparison to forty-seven cents ($0.47) per share in 1995. The
earnings per share were impacted by the dilution effect of one cent ($.01) per
share due to the impact on the average common stock outstanding of the
1,000,000 shares of common stock issued December 8, 1995 to MLTV to purchase
the technology rights and related joint venture interest. On a fully diluted
basis (which gives consideration to all non-exercised and issued employee
options, and options issued to Covington Capital Corporation as part of the
subordinated debt financing agreement) the earnings per share was ten cents
($0.10). The prior years have been restated on the same basis to reflect the
Reverse Split and fully diluted earnings per share for comparative purposes
only.

  FISCAL YEAR 1995 COMPARED TO FISCAL YEAR 1994
 
  Net sales of $7,792,000 in 1995 increased $2,404,000 or 44.6% from
$5,388,000 in 1994. This increase primarily reflected increased sales in the
ratio-fluorescence product group and increased sales from all the Company's
domestic and international operations.
 
  Total revenue of $7,848,000 in 1995 increased $2,337,000 or 42.4% from
$5,511,000 in 1994. This change directly related to the increased net sales
and was partially offset by decreased nonrecurring research revenues in
comparison to the same period in the prior year. Research contract revenues
had been fully recognized in fiscal 1994 pursuant to the expenditures schedule
entered under the research and development agreement with MLTV in 1987. The
"other income" component of total revenue increased by $10,000 or 22.2% over
1994 as a result of funding from the Canadian government for direct labor
training support programs.
 
  Cost of products sold of $3,322,000 for fiscal 1995 increased in dollars
terms by $954,000 or 40.3% in comparison to cost of sales of $2,368,000 in
fiscal 1994. On a percentage of net sales basis, cost of products sold
decreased from 43.9% to 42.6% for the comparative periods. This dollar cost
increase in cost of sales related to the increased sales volume. The decrease
as a percentage of net sales in comparison to the prior year reflected (a) the
impact of component material cost reductions through re-engineering of
specific products and material sourcing and (b) fuller absorption of overhead
costs due to efficiency and higher production volume throughput to support
increased sales volumes.
 
  Selling, general and administrative expenses $3,175,000 in fiscal 1995
increased $811,000 or 34.3% over fiscal 1994. This increase reflected (a) the
impact of higher sales volume on variable selling related expenses, (b) the
addition of sales personnel associated with the German Subsidiary sales
office, (c) the addition of sales personnel in North America to expand
territory coverage and (d) executive administrative support expenses
associated with the German Subsidiary and sales office. On a percentage of net
sales basis, selling, general and administrative expenses decreased 43.9% in
fiscal 1994 to 40.7% in 1995, as the dollar increase in such expenses was
offset by increased net sales.
 
  Research and development expenditures, $571,000 or 7.3% in fiscal 1995,
compared to $308,000 or 5.7% of net sales in fiscal 1994, an increase of
$263,000 or 85.4% of net sales. The fiscal 1994 expenses included research
contract expenses of $73,000 reimbursed under the MLTV research and
development agreement, while fiscal 1995 expenses did not as a result of these
expenses having been fully recognized in fiscal 1994. This increase primarily
related to additional personnel for software development and maintenance
support and outside contract engineering support for new product development.
In addition, the Company had capitalized a portion of software development
costs in the amount of $255,000. This capitalization was done in accordance
with generally accepted accounting practices (FASB Statement No. 86
"Accounting for Software Costs"), as a result of obtaining technical
feasibility for the software product called "Felix", which was completed and
released in April 1995. In terms of gross dollars spent with the addition of
capitalized software costs, the actual research and development expenditures
were $826,000 or 10.6% of net sales for fiscal year 1995, which was higher
than the prior year due to these strategic product development activities. The
Company's goal is to target at least 10% of its net sales to research and
development. The percentage over the last three prior years has been in the 8%
of net sales range. It has been difficult to maintain this target level of
spending due to allocation of financial resources. The Company continues to
seek additional financial resources in order to increase investment in this
strategic area.
 
  Interest expenses were $122,000 in fiscal 1995 compared to $88,000 in the
prior year, which represented an increase of $34,000 or 39.1%. This increase
primarily related to interest expenses of $41,000 incurred by the German
Subsidiary, which were related to interest charges on both its 500,000 German
mark line of credit with the bank, and a loan for 400,000 German marks by an
individual. Additionally, interest expenses of $17,000 related to the ODC
fixed term loan which was incremental year to year. This increase was
partially offset by lower interest expense related to the Company's other
credit facilities.

  Depreciation and amortization expenses were $148,000 in fiscal 1995 which
represented an increase of $60,000 or 68.1% from $88,000 in 1994. This was
primarily due to the impact of depreciation on capital equipment expenditures
completed during fiscal 1994 for the Canadian's plant operation.
 
  Goodwill amortization of $106,000, which is an incremental expense in
comparison to the prior year, is related to the formation and start-up of the
German Subsidiary. The total amount of goodwill represents $686,000, and is
amortized using a straight line method over a five year period.
 
  Foreign exchange was a gain of $81,000 in fiscal 1995 compared to a loss of
$20,000 in fiscal 1994. Foreign exchange gains and losses are primarily
related to the level of cash transactions denominated in foreign currency and
the fluctuation of this foreign currency in comparison to the U.S. dollar.
There was an increase in cash transactional activity involving all
international locations and the U.S. parent company in fiscal 1995. The most
significant transaction was the transfer of funds (292,000 US$) from Canada to
pay in full the outstanding balance with Midlantic Bank as part of the
agreement with the Bank of Montreal.
 
  Deferred tax expense of $86,000 related to a timing difference between book
and tax income, as a result of the capitalization of the excess of liabilities
over acquired assets in the formation and start-up of the German Subsidiary.
This subsidiary was 51% owned and fully controlled by the Company as of June
30, 1995. This deferred tax was recorded in accordance with generally accepted
tax accounting principles. (See Note F).
 
  Minority interest of $42,000 represents an adjustment to consolidated net
income of the Company in order to exclude the 49% minority ownership position
of the shareholders of the German Subsidiary. As a result, only 51% of the net
income of the German Subsidiary is reflected in the reported consolidated
income. The minority interest was cleared in July 1995 of fiscal year 1996 as
a result of the acquisition by the Company of the 49% minority ownership. (See
Note L).
 
  As a result of the foregoing, the Company reported net income for fiscal
1995 of $357,000 in comparison to net income of $202,000 in fiscal 1994, an
increase of $155,000 or 77% over the prior year.
 
  As a result of this net income performance, earnings per share based on
average common shares outstanding represented sixteen cents ($0.16) for 1995
in comparison to nine cents ($0.09) per share for 1994, before consideration
of the Reverse Split.
 
 FACTORS THAT MAY AFFECT FUTURE RESULTS
 
  The Company believes that results of operations in any period could be
impacted by factors such as delays in the shipments or lack of market
acceptance of new products, a slower growth rate in the Company's target
markets, order deferrals in anticipation of new product releases, increased
competition, adverse changes in general economic conditions in any of the
countries in which the Company does business, or reduction or delay of private
sector and government spending on research activities.
 
 LIQUIDITY AND CAPITAL RESOURCES
 
  The working capital of the Company at June 30, 1996 was $1,543,000 as
compared to $1,026,000 at June 30, 1995, an increase of $517,000 or 50.3%.
 
  Current assets of $4,661,000 increased $1,250,000 or 36.6% in comparison to
the prior year. This change primarily reflects increases in (a) cash of
$233,000, (b) trade accounts receivable of $811,000 or 57.3% and (c) inventory
of $253,000 or 15.4%. The net increase in cash was primarily due to financing
activities which mostly covered the cash used in operations and investing
activities. The dollar increase in trade receivables reflected the impact of
$1.1 million in sales for the year end month of June 1996. The accounts
receivable balance of $2.2 million represented 2.8 months of sales in
comparison to 1.9 months of sales in the prior year. The increase in months of
sales reflected the impact of the June 1996 sales volume and a slower turn on
international receivables, which represented 38% of total receivables.
 
                                      17
<PAGE>
 
  The inventory balance of $1.9 million represents 5.3 months of sales in
inventory based on anticipated sales volume and compares to 4.9 months of
sales in the prior year. The change in inventory primarily reflected a
production build of product inventory based on the anticipated volume of sales
in the last half of the fiscal year, which did not reach projected levels.
 
  Current liabilities of $3,118,000 increased $733,000 or 30.8% in comparison
to the prior year. This increase was primarily due to: (a) net increased bank
indebtedness on short term credit facilities of $500,000 or 48.8% for working
capital requirements and (b) increase in trade accounts payable of $209,000 or
27.0% primarily related to open vendor payables at PhotoMed, which were on
extended terms due to cash flow considerations.
 
  The increment ($500,000) in bank indebtedness is related to the Bank of
Montreal line of credit with an outstanding balance of $1.3 million ($1.7
million Canadian dollars) at June 30, 1996. The Company used a portion of the
Silicon Valley credit facility to pay off the Bank of Montreal credit facility
subsequent to June 30, 1996.
 
  Bank indebtedness includes the line of credit with the German Stadtparkasse
Bank to support the German Subsidiary operations. The outstanding balance as
of June 30, 1996 was $246,000 (375,000 DM) which was lower than the prior year
by 96,000 or 28.0%. The authorized line of credit is 500,000 DM (US$362,000)
which was established in September 1994 at the time of formation of the German
Subsidiary. The German Stadtparkasse line of credit was renewed for fiscal
1997 under the same terms and conditions.
 
  On November 20, 1989, the Company entered into a sale/leaseback agreement
with a leasing company. At that time the Company sold certain demonstration
inventory used by the sales and marketing departments for $299,950 resulting
in a $176,750 gain, which has been recognized over the lease term using the
effective interest rate method. The balance of the gain in the amount of
$3,000 was recognized in fiscal year 1995. Under the terms of the agreement,
the Company agreed to lease back the equipment under a noncancelable five year
term. At the end of the lease term in December 1994, the Company had the
option to purchase the equipment at fair market value or extend the lease for
a one-year period. The Company negotiated a renewed lease for $35,000 to be
paid over eighteen (18) months at an interest rate of 10.25%. Payments under
the original capital lease obligation had an effective interest rate of 11.8%.
The renewed capital lease contained a bargain purchase option and on June 11,
1996, the Company exercised this bargain purchase option and purchased the
equipment for one (1) dollar.
 
  The Company entered into an agreement with New Court Credit Corporation of
Toronto, Canada in March 1996 to finance the purchase of a CNC milling machine
for the Canadian plant machine shop. The term loan amount was for $90,000
Canadian dollars ($66,000 US). Interest payments for fiscal 1996 were
$2,000 Canadian dollars ($1,500 US). The balance of the debt at June 30, 1996
was $85,000 Canadian dollars ($62,000 US) with $10,000 classified as the
current portion of the long term debt. The term of the financing is 5.5 years
at an annual interest rate of 10.4%, and a purchase option of $9,000 at the
end of the fifth year.
 
  As of June 30, 1995 the Company had a notes payable balance of $44,000 with
Brooks Air Force Base, which was a current liability under the current portion
of long term debt. This amount was paid in full by June 1996. This debt arose
from a duplicate payment and installment payment agreement between Brooks Air
Force and the Company for the principal amount of $90,155 in March 1994.
 
  The December 1995 MLTV Agreement provided for repayment of subordinated debt
in the amount of $771,000, the purchase by the Company of the technology
developed under the Joint Venture and the acquisition of MLTV's interest in
the Joint Venture, thereby dissolving the Joint Venture. As it relates to the
subordinated debt the Company agreed to pay the principle amount of $20,000 a
month for a twenty-four (24) month period for a total of $480,000. The balance
of $291,000 is due at the end of the two year term. As of June 30, 1996, the
Company has paid $140,000 and reduced the total outstanding balance to
$631,000. The Company is not required to pay any additional interest on the
outstanding balance under this agreement unless the Company makes a late
payment or an event of default under the terms of the agreement occurs. On
June 21, 1996, MLTV agreed to
 
                                      18
<PAGE>
 
defer four payments from June 1996 through September 1996. The deferred amount
will be subject to interest in accordance with the agreement. The Company
purchased the technology and the joint venture interest by issuing to MLTV
1,000,000 shares of the Company's common stock. The stock is unregistered and
restricted. As of December 8, 1995, the 1,000,000 shares have been recorded in
paid-in-capital at the fair market value of .875 per share based on the market
bid price. This $875,000 value has been assigned to the technology as an
intangible asset under the "other assets" classification and will be amortized
over a five (5) year period. As of June 30, 1996, the asset balance was
$831,000, net of amortization of $44,000 during the fiscal year. This was a
strategic agreement for the Company in that the Company now owned the
technology rights and there was no future liability for royalties.
 
  On October 31, 1995, the Company entered into a Debenture agreement for $1.5
million Canadian dollars ($1.1 million US) through C.I.-C.P.A Business
Ventures Fund, Inc. a venture capital fund of Covington Capital Corporation
("Covington Capital") (the "Covington Agreement"). This subordinated debt has
a term of five (5) years at an interest rate of 12% per annum. Interest
payments are payable only in the first twelve (12) months. As of June 30,
1996, the Company had made interest payments totaling approximately $119,000
Canadian dollars ($87,000 US). This Covington Agreement includes a fist option
to purchase 250,000 shares of the Company's common stock at a purchase price
of $1.25 per share for a term of five (5) years and a second option to
purchase 400,000 shares of the Company's common stock at purchase price of
$2.50 per share until October 1996. After October 31, 1996 the purchase price
increases to $3.25 per share. The Option terminates on October 1, 1997. This
debt is classified primarily as long term debt with principal payments of
$31,500 due in fiscal 1997 recorded as current debt. The balance outstanding
as of June 30, 1996 was $1,100,000 ($1.5 million Canadian dollars). Payments
of principal will commence on November 30, 1996 in the amount of $6,250
Canadian dollars ($4,500 US) per month for a period of forty-eight (48) months
with the balance due at the end of the term. This financing was an important
source of funds during fiscal 1996 which provided for investment to expand
sales territory coverage through addition of personnel, increase marketing
support, and continue research and development efforts in both hardware and
software for new products and product cost reductions. There has been no
exercise of options through June 30, 1996.
 
  Long term debt also includes a 400,000 DM loan ($291,000 US) by a private
individual (who is also an investor in the subsidiary) to the Company's wholly
owned German subsidiary, German Subsidiary. The loan was made to the
subsidiary on October 1, 1994. The Company began making payments of principal
and interest of 10,000 german marks per month at the end of April 1995.
Interest accrues from October 1 through the start date of the payments at an
interest rate of 5.25% plus the prevailing German bank discount rate (i.e.
4.5%). The loan has clauses which would allow both slower and/or faster
payments contingent upon the cash flow of the German Subsidiary operations. As
of June 30, 1996, the principal amount of $353,000 German marks ($231,000 US)
was outstanding. A portion of this outstanding amount ($47,000 US) has been
classified as a current liability and represents an estimated twelve payments
of principal. The balance ($184,000 US) has been reported as a long term debt.
Payments on a monthly basis are contingent upon cash flow considerations and
upon agreement with the individual.
 
  In July 1994, documents were fully executed between the Ontario Development
Corporation ("ODC") and the Company for a term loan facility in the amount of
$500,000 Canadian dollars. The loan credit facility was established to allow
advance requests for equipment, inventory and training expenditures associated
with moving the production operation from the New Jersey plant to the London,
Ontario, Canadian plant. This loan was a "carve out" from the original ODC
credit facility of $900,000 Canadian dollar limit, prior to the full payment
of the outstanding balance from the Bank of Montreal credit facility in May
1995. The balance outstanding as of June 30, 1996 on the ODC fixed loan was
$415,000 Canadian dollars ($304,000 US) based on specific advance requests
approved through this date. Payment of principal was scheduled to start August
15, 1995 (of fiscal 1996) in that full disbursement had not occurred by June
30, 1995. The Company had been granted an extension by ODC until June 30, 1996
with principal payments in the amount of $11,597 Canadian dollars ($8,500 US)
having started on July 15, 1996. The term of repayment is forty (40) months
and includes an interest rate of 6.75%. Interest has been charged on a monthly
basis since the first disbursements made on July 1994, and interest paid
 
                                      19
<PAGE>
 
amounted to $19,000 this fiscal year. The Company may not draw additional
funds on the facility for capital equipment up to $500,000, the original
facility amount, due to Ontario government budgetary constraints. This term
loan is classified as a long term debt with a current portion equal to twelve
months of principal payments.
 
  On July 5, 1995 the Company acquired control of the German Subsidiary by
issuing 150,000 shares of the Company's treasure stock. The stock was valued
at a fair market value of $1 per share. (See "BUSINESS--General") As a result
of this transaction, the German Subsidiary became a wholly-owned subsidiary of
the Company. The German Subsidiary operation was financed through the
utilization of a 400,000 DM ($290,000 US) shareholder long-term loan, 500,000
DM ($362,000 US) bank revolving line of credit, and cash provided by
operations. The cash start-up expenses were approximately $1,000,000, which
had a major impact on working capital requirements and are non-recurring
expenses going forward. In fiscal 1996 there were some additional assumption
of liabilities in the amount of $83,000 at the time of acquisition of the 49%.
 
  Overall, the amount of cash provided by financing activities allowed the
Company to meet working capital requirements, which included support of all
operating and investing activities, and payments on debt obligations.
 
  In the area of operating activities, the Company's sales growth and
continued reduction in cost of sales (on a percentage of sales basis) provided
a strong contribution to operating income. The contribution along with
financing activity supported (a) investments in sales, marketing, research and
development (b) meeting regulatory obligations to sell into the EC (c) payment
of fees, interest and principal, where applicable, related to financing
agreements.
 
  The investments in the operating areas of sales, marketing and research and
development are strategic to future growth and had an impact on current year
income results due to the time that is required for these investments to be
leveraged or provide a contribution.
 
  The expenses associated with meeting regulatory requirements for our
products are necessary to be able to sell into the EC and the Company will
incur additional expenses going forward to complete certification of its
current product line and to certify our new products at time of introduction
to the marketplace. This could provide a competitive advantage if our
competitors have not or cannot comply. If the Company does not comply there
could be risks to the Company's ability to sell in the EC and a potential
competitive disadvantage.
 
  The payment of interest, payment and fees have been increasing as the
Company completes new financing agreements and maximizes the use of the
available short term credit lines to support working capital requirements. The
Company's financing to date has been primarily short term debt through
operating lines of credit, term loans and subordinated debt. The Company's
bank lines of credit, which are supported by sales generated trade accounts
receivable, have limited borrowing capacity at this time because these lines
of credit are close to the maximum qualified borrowing levels. The term loans,
which had deferred principal payments are now under a scheduled payment
agreement. The subordinated debt--MLTV ($600,000) and Covington Capital ($1.1
million)--totals $1.7 million, and will require payments of $400,000 on an
annual basis (with interest and principal as applicable) until the end of the
respective term and a balloon payment comes due--MLTV in December 1997 (fiscal
year 1998) and Covington Capital in October 2000 (fiscal year 2001).
 
  During fiscal 1996, working capital enabled the Company to grow sales 18%,
expand sales territory coverage, continue and increase software development
efforts and increase hardware development which resulted in several new
products, and certify approximately 60% of our product systems for sales into
the EC. These efforts put pressure on the bottom line income and operating
cash flow in that our investment exceeded the sales growth contribution for
the twelve (12) months of this fiscal year. These investments were necessary
and are important to the future performance of the Company and must continue
at a level which our financial resources can support.
 
  The Company will continue to manage within its financial resources and
attempt to balance its working capital needs with cash flow generated from
operations and available current financing. The Company will not
 
                                      20
<PAGE>
 
consider any incremental long term debt and work with current operating lines
of credit. The Company will consider additional financing through the form of
equity to accelerate and support growth in sales and to increase the
investment levels in research and development for new products and for
continued cost reduction to improve sales margin contribution. The Company
cannot be certain that it will be successful in efforts to raise additional
funds.
 
 INFLATION
 
  The Company believes that there has not been a significant impact from
inflation on the Company's operations during the past three fiscal years.

and reports of changes in ownership of Common Stock and other equity
securities of the Company. Officers, directors and greater than ten-percent

(1) The amount reported includes compensation accrued and/or paid in a given
    fiscal year. Mr. Marianik's fiscal 1996 compensation excludes $48,825
    which was accrued and reported in fiscal 1995. This amount represents a
    deferred base pay from fiscal year 1995 due to cash flow considerations.
(2) On May 15, 1996 certain executive officers of the Company agreed to a
    reduction in annual base salary as follows: Mr. Marianik 20% or $38,491,
    Mr. Kovach 10% or $12,416 and Mr. Looney 10% or $11,795. These salary
    reductions were done to reduce costs and to conserve cash. The impact on
    salary compensation for fiscal 1996 was $4,811 for Mr. Marianik, $1,552
    for Mr. Kovach and $1,474 for Mr. Looney.
(3) There were no cash bonuses paid in fiscal 1996 due to cash flow
    considerations. On October 28, 1994, the Company issued to Mr. Marianik,
    Mr. Kovach and Mr. Looney, treasury stock in lieu of a cash bonus approved
    for fiscal 1994. Mr. Marianik, Mr. Kovach and Mr. Looney, each received
    8,000 fully vested shares of common stock at $1.25 per share. The stock
    price represented fair market value on the date of issuance. The aggregate
    amount of stock holdings are as follows: Mr. Marianik 846,718 shares, Mr.
    Kovach 77,000 shares and Mr. Looney 36,654 shares. These numbers do not
    reflect the Company's recent Reverse Split.
(4) These amounts reflect personal benefits received by each Named Executive
    Officer during the 1996 fiscal year. These personal benefits include
    payments made on behalf of those individuals for (a) use of automobiles,
    which include $950 for Mr. Marianik, $2,717 for Mr. Kovach and $4,078 for
    Mr. Looney (b) disability insurance premiums, which include $1,666 for Mr.
    Marianik, $1,365 for Mr. Kovach and $1,077 for Mr. Looney (c) medical
    expenses not otherwise covered by the group plan, which include $2,994 for
    Mr. Marianik and $214 for Mr. Looney and (d) all income taxes attributed
    to these and paid by the Company as a result of their receipt of these
    personal benefits, which include $26,938 for Mr. Marianik, $4,879 for Mr.
    Kovak and $5,883 for Mr. Looney.
(5) On December 8, 1995, the Compensation Committee of the Board of Directors
    granted options to purchase shares of common stock of the Company pursuant
    to the Company's Stock Option Plan to each Named Executive Officer based
    on 15% of gross annual base pay on that date. These numbers do not reflect
    the Company's recent Reverse Split.
(6) These amounts reflect supplemental term life insurance premiums for each
    Named Executive Officer which includes for the 1996 fiscal year a premium
    of $2,946 for Mr. Marianik, $703 for Mr. Kovach and $1,320 for Mr. Looney.
    For Mr. Marianik, these amounts also include the premiums of $33,037 for
    the 1996 fiscal year paid on a permanent-whole life insurance policy,
    having an accumulated cash value of $93,973 June 30, 1996. For Mr. Kovach,
    these amounts also include a premium of $5,116 for a permanent-whole life
    policy with an accumulated cash value of $5,264. For Mr. Looney, these
    amounts include a premium of $4,456 for a permanent-whole life policy with
    an accumulated cash value of $2,585.

(1) All options granted to Named Executive Officers are incentive stock
    options under the federal tax laws and were granted on December 8, 1995.
    Pursuant to the option agreement evidencing these options, the options
    were to become exercisable in three (3) successive equal annual
    installments upon the optionee's completion of each year of service with
    the Company over the three (3)-year period measured from the grant date.
    However, the purchase by MLTV of 1,000,000 shares (pre-Reverse Split) of
    the Company's common stock on December 8, 1995 caused a change in the
    ownership of more than twenty percent (20%) of the Company's outstanding
    voting securities, and as a result, each option became fully exercisable
    for all of the option shares under the terms of each option agreement. The
    options granted to Messrs. Kovach and Looney each have a maximum term of
    ten (10) years, subject to earlier termination in the event of the
    optionee's cessation of employment with the Company. The option granted to
    Mr. Marianik has a maximum term of five (5) years.
(2) The exercise price may be paid in cash or in shares of the Company's
    common stock. Alternatively, the option may be exercised through a same-
    day sale program with no cash outlay required of the optionee.
(3) There is no assurance provided to any executive officer or any other
    holder of the Company's securities that the actual stock price
    appreciation over the 5-year or 10-year option term will be at the assumed
    5% or 10% annual rates of compounded stock price appreciation or at any
    other defined level. Unless the market price of the Common Stock
    appreciates over the option term, no value will be realized from the
    option grants made to the executive officers.
 
                         FISCAL YEAR-END OPTION VALUES
 
  The following table sets forth information regarding the number and value of
unexercised options held by each of the Named Executive Officers as of June
30, 1996. None of the Named Executive Officers exercised any stock options in
1996. No stock appreciation rights were exercised during such year or were
outstanding at the end of that year. These numbers do not reflect the Reverse
Split.

 DIRECTOR REMUNERATION
 
  Directors have not been paid a fee for serving on the Board or any
committees of the Board with the exception of Mr. Brown who receives a per
meeting fee of $750 (Canadian Dollars) as part of the financing agreement with
Covington Capital Corporation. Directors are reimbursed for expenses related
to attending Board or committee meetings and annually are granted non-
qualified stock options to purchase the Company's common stock under the
automatic option grant provision of the Company's Stock Option Plan, as
amended (the "Plan"). In the fiscal year ended June 30, 1996 the Company paid
an aggregate of $2,700 for director traveling expenses. In addition, each non-
employee director received an option grant to purchase 10,000 shares of Common
Stock on December 8, 1995 at an option price of $1.06 per share under the
Automatic Option Grant Program in effect for non-employee directors under the
Company's Stock Option Plan. Each option has a maximum term of ten (10) years
measured from the grant date, subject to earlier termination following the
optionee's cessation of Board service. Each option is immediately exercisable
for all of the option shares; however, any shares purchased under the option
will be subject to repurchase by the Company, at the option exercise price
paid per share, upon the optionee's cessation of Board service prior to
vesting in those shares. The shares subject to each grant will vest in three
successive equal annual installments upon the optionee's completion of each
year of Board service over the three-year period measured from the grant date.
However, the option shares will immediately vest in full upon certain changes
in control or ownership of the Company or upon the optionee's death or
disability while serving as a Board member.
 
  EMPLOYMENT AGREEMENTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
AGREEMENTS
 
  On June 30, 1996, the employment agreement between the Company and Mr.
Marianik was automatically extended for one year in accordance with the terms
of the contract. This employment agreement entitles Mr. Marianik to a base
salary of $192,452 in 1997 but Mr. Marianik agreed to a 20% reduction in his
base compensation to $153,961 for cost reduction and cash flow considerations.
Under such agreement, Mr. Marianik is to be employed by the Company in an
executive capacity as Chairman of the Board, Chief Executive Officer and
President, or in a position substantially similar thereto. In the case of (i)
a change in control, sale or merger of the Company, (ii) the termination of
his employment without cause, or (iii) a substantial change in his position
with the Company, Mr. Marianik will be entitled to receive a minimum of two
years of salary continuation (including bonuses), as well as to retain certain
employee benefits, including an automobile and a life insurance policy, paid
in full by the Company. There are no other employment agreements with any
other Named Executive Officer.
 
  Pursuant to the express provisions of the Stock Option Plan, the outstanding
options under the Plan held by the Chief Executive Officer and the Company's
other executive officers will immediately accelerate in full and become
exercisable for all of the shares at the time subject to that option in the
event the Company is acquired by merger, consolidation or asset sale, unless
the option is to be assumed by the successor corporation or otherwise replaced
with a comparable option to purchase the shares of such successor corporation.
 
  Pursuant to the terms of the agreements evidencing the outstanding options
Certain outstanding options, the options will also accelerate and become
immediately exercisable for all of the shares at the time subject to those
options, should there occur certain changes in the ownership of more than
twenty percent (20%) of the Company's outstanding voting securities or in the
event there is a change in the majority of the Board members as a result of
any tender for the Company's outstanding voting securities, merger or other
business combination, or proxy contest for the election of Board members. On
December 8, 1995, MLTV purchased 1,000,000 shares of the Company's common
stock resulting in a change in ownership of more than 20% of the Company's
outstanding securities and the acceleration of the exercisability all of the
then outstanding options.
 
  No executive officer of the Company served on the board of directors or
compensation committee of any entity that has one or more executive officers
serving as a member of the Company's Board of Directors or Compensation
Committee.

                        REPORT OF INDEPENDENT AUDITORS
 
To the Shareholders and the Board of Directors of
Photon Technology International, Inc.
 
  We have audited the accompanying consolidated balance sheets of Photon
Technology International, Inc. as of June 30, 1996 and 1995, and the related
consolidated statements of operations, shareholders' equity, and cash flows
for each of the three years ended June 30, 1996. Our audits also included the
financial statement schedule listed in the index at item 14(a). These
financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.
 
  We conducted our audit in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Photon Technology
International, Inc. and subsidiaries as of June 30, 1996 and 1995, and the
results of their operations and their cash flows for each of the three years
then ended June 30, 1996 in conformity with accounting principles generally
accepted in the United States. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)
 
                                 JUNE 30, 1996
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Photon Technology International, Inc. (the "Company") is engaged in
research, development, manufacturing, sales and marketing of proprietary
electro-optical systems which enable customers in health care, environmental
science and industrial process control to perform advanced analysis utilizing
light. The Company's major products are electro-optical and light-based
instrumentation which utilizes fluorescence technology. The primary markets
are medical life sciences, physical sciences, environmental and industrial.
 
  The Company operates in one principal industry segment, the photonics
industry. The Company's products are sold on a worldwide basis to
universities, research hospitals, pharmaceutical companies, bio-tech
companies, federal and state government institutions, environmental companies
and commercial businesses, all of which are primarily engaged in research
activities.
 
  The following is a summary of the significant accounting policies followed
in the preparation of the consolidated financial statements of the Company.
 
1.  PRINCIPLES OF CONSOLIDATION
 
  The consolidated financial statements of the Company include the accounts of
Photon Technology International, Inc., its wholly owned subsidiaries in Canada
and in Germany (see Note L), and a domestic joint venture in which the Company
had a controlling interest through December 8, 1996 (see Note B). All
significant intercompany transactions and balances are eliminated in
consolidation.
 
2.  FOREIGN CURRENCY TRANSLATION
 
  Assets and liabilities of the Company's international operations are
translated into U.S. dollars using year-end exchange rates. Income and expense
accounts are translated into U.S. dollars at average rates of exchange
prevailing during the year. The resulting translation adjustments are recorded
as a separate component of the shareholders' equity. Gains and losses from
foreign currency transactions are reported in income.
 
3.  CASH AND CASH EQUIVALENTS
 
  Cash and cash equivalents consist of temporary money market instruments with
an original maturity of 3 months or less, and are stated at cost plus accrued
interest which approximates market.
 
4.  INVENTORY
 
  Inventory is stated at the lower of cost or net realizable value for work in
process and finished goods and at the lower of cost or replacement cost for
raw materials. The cost of inventory is determined using the first in, first
out method.
 
5.  PROPERTY AND EQUIPMENT
 
  Property and equipment are carried at cost. Depreciation is computed using
the straight-line method over the estimated useful life of the assets, which
range from three to ten years. At the time of disposal of assets, both the
cost and accumulated depreciation related to the particular assets are removed
from the appropriate accounts and any gains or losses are included in income.
Major renewals and betterment of assets are capitalized.

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)--(CONTINUED)
 
6.  OTHER ASSETS
 
  Software development costs are capitalized in accordance with the guidance
of FASB Statement No. 86 "Accounting for Software Costs", which provides for
the capitalization of costs incurred from the point of establishing
technological feasibility until the general release of the software.
Amortization of software product development costs is computed using the
straight-line method over the estimated economic life of the products, which
is approximately five years. Software is an integrated component and included
with each product system sale.
 
  Goodwill, which represents the difference between the purchase price of an
acquired business (German Subsidiary), and the related value of net assets
acquired or net liabilities assumed, is reported net of amortization, and is
amortized using the straightline method over a five year period.
 
  Technology rights acquired through issuance of the Company's shares of
common stock is valued at the bid price of the stock at the date of
transaction. These technology rights will be amortized on a straight line
basis over a ten (10) year term.
 
  Direct costs related to financing are deferred and amortized on a straight
line basis over the term of the related financing agreement.
 
  On an ongoing basis, management assesses the carrying value of its
intangible assets to determine if there is an impairment in value by comparing
expected undiscounted cash flow to the carrying value and reviewing other
relevant factors that may affect carrying value.
 
7.  REVENUE RECOGNITION
 
  Revenue is recognized when the risks and benefits inherent in ownership are
transferred, which normally occurs at the time of shipment of products.
Revenue under extended warranty and maintenance contracts is deferred and
recognized in income as the related services are performed.
 
  Research contract revenue is recognized as earned, based on expenses
incurred plus a 5% profit as provided by an agreement with Merrill Lynch
Technology Venture, L.P. ("MLTV"). Research contract payments which relate to
future performance are deferred and taken into income as earned over a
specified future performance. Research contract costs are expenses as
incurred. Research revenue and research contract expense are applicable to
fiscal 1994 and prior years.
 
8.  INCOME TAXES
 
  The liability method is used in accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax basis of assets and
liabilities that are expected to reverse.
 
9.  NET INCOME PER COMMON SHARE
 
  Net income per common share is computed by dividing net income by the
weighted average number of common shares outstanding during the year. The
weighted average number of common shares outstanding during the year has been
computed on a post-Reverse Split basis and fully diluted basis. The fully
diluted share number includes all share options issued in a financing
agreement with Covington Capital, to non-employee directors, to executive
management and to employees.

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)--(CONTINUED)
 
10. LEASES
 
  Leases are classified as capital or operating leases. Leases which transfer
substantially all of the benefits and risks incident to ownership of property
are accounted for as capital leases. Assets required under capital leases are
amortized on a straight-line method using rates based on the estimated life of
the asset or based on the lease term as appropriate. All other leases are
accounted for as operating leases and the related lease payments are charged
to expense as incurred.
 
NOTE B--RESEARCH AND DEVELOPMENT AGREEMENT
 
  On April 6, 1987, the Company entered into a research and development
agreement with MLTV, a related party. The agreement provided that MLTV pay the
Company $3,133,000 to develop new photonic technologies with applications in
the medical field. MLTV would own all the technology rights to the products
developed under the terms of the agreement. The agreement provided for the
development of four products ("MLTV Products") and the fourth product was
completed to a prototype stage during fiscal 1996.
 
  In March of 1990, upon the sale of the first MLTV Product, the Company
entered into a partnership and joint venture agreement with MLTV to market all
of the MLTV Products.
 
  On December 8, 1995, the Company entered into an agreement with MLTV whereby
the Company issued 1,000,000 shares of common stock (333,333 on a post split
basis--See Note G) to purchase the technology rights and related joint venture
interest in the product developed under the Research and Development Agreement
between the Company and MLTV. The 1,000,000 shares of common stock is in full
settlement of all obligations of the Company related to the technology rights
and joint venture interest. The technology rights were valued at $875,000,
using the bid price of the Company's shares at $0.875 per share on the day of
transaction, which in management's opinion is the most objective measure of
the value of the technology rights. As a result of this agreement, the joint
venture between the Company and MLTV terminated.

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)--(CONTINUED)
 
  In May 1995, the Company executed an agreement with the Bank of Montreal
Innovation and Technology Center (the "Bank") for a $1.5 million Canadian
dollars and/or Canadian dollar equivalent (in US dollars $1.1 million), credit
facility in the form of a revolving line which is payable on demand. The
availability of funds on this facility were subject to margin requirements.
 
  On March 5, 1996, the Company renewed its credit facility with the Bank of
Montreal for $2.0 million Canadian dollars ($1.5 million equivalent in US
dollars). The terms and conditions of the facility were the same with the
exception of changing the covenants to exclude Total Debt to Tangible Net
Worth Ratio, which became an interest rate tierred pricing incentive. Interest
was charged at Canadian prime rate plus 2.25%. The purpose of this facility
was to provide incremental working capital to the Company.
 
  On July 26, 1996 the Company secured a new working capital line of credit
facility with Silicon Valley Bank of California for $2,000,000 (U.S.) and
repaid the Bank of Montreal credit facility in full. This credit facility has
a one (1) year term (expiring June 30, 1996) and carries interest rate change
of prime rate plus 1.5% (approximately 8.75%). Interest is due and payable
monthly, and the principal is due at maturity. The collateral for the line
represents a perfected first security interest in all assets of the Company,
its wholly-owned Canadian subsidiary and United Kingdom branch office. The
Company will retain ownership of intellectual property and is restricted on
the pledge of this property to any other party. The advance rate is based on
75% against eligible domestic and Canadian receivables within 90 days from
invoice date and 90% against incurred or letter of credit backed foreign
receivables. There is no clean-up period required during the term. The
securities related to the Covington Capital debenture and the MLTV note are
subordinated to the bank debt. The outstanding balance of $1.3 million
represents the amount used to repay the Bank of Montreal facility. The Company
has not borrowed additional amounts on this line at this point.
 
  Bank indebtedness also includes the outstanding balance of $246,069 US
(375,000 DM) drawn on a credit facility with the Stadparkasse Bank of Wedel,
Germany. The total line of credit available is 500,000 DM, which was
established in conjunction with the formation of the German Subsidiary (See
Note L). Interest is charged on a quarterly basis at the German Federal Bank's
discount rate plus two points. The weighted average interest rate on short
term borrowings outstanding during the year is 9.25% (1995: 9.36%).

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)--(CONTINUED)
 
  In connection with the Company's research and development efforts, MLTV had
previously provided the Company with subordinated debt of $770,761, which was
used to fund the continuing development of the MLTV products (see note B).
 
  On September 20, 1995, the Company entered into an agreement with MLTV.
Under this agreement, the Company was to repay the existing $770,761
subordinated debt, without interest charged or accruing over a two year
period, commencing October 1995. The repayment is in the amount of $20,000 per
month, with the remaining balance to be paid in full at the end of this term.
As of June 30, 1996, the Company has repaid $140,000 and reduced the balance
outstanding to $630,761. MLTV agreed to defer payments for a four month period
from June 1996 through September 1996 in consideration of the Company's sales
and marketing plans. The Company will pay interest on the deferred amounts at
a rate of 12% per annum during the four month period. Interest paid during
fiscal 1996 was $200. The Company granted a security interest in all of the
Company's right, title and interest in all amounts and proceeds. This
collateral is subordinated to the bank debt.
 
  On February 3, 1994 the Company received from ODC an "offer of loan" for a
$500,000 Canadian dollar fixed term loan at an interest rate of 6.75% for a
term of 4.5 years. This term loan was originally part of a ODC credit facility
of $900,000 Canadian dollars under the Export Loan Program. The loan was based
on specific advance requests for equipment, inventory, and training
expenditures to finance the relocation of production operations from the New
Jersey plant to the London, Ontario, Canadian plant.
 
  Payment of principal was originally scheduled to start on the earlier of
full disbursement or August 15, 1995. Since the full disbursement had not
occurred by June 30, 1995, the Company was granted an extension by ODC until
June 30, 1996. Principal payments began on July 15, 1996 for an amended period
of 40 months at a rate of $11,597 Canadian dollars ($8,500 US) per month which
includes principal plus interest. Interest has been charged on a monthly basis
at a stated rate of 6.75% effective since July 1994. Interest paid during
fiscal 1996 was $19,000 and the principal balance at June 30, 1996 was
$415,000 Canadian dollars ($304,000 US). The Company provided a security
interest in all chattel owned and acquired under this loan program. ODC waived
a floating charge on all assets in subordination to the bank debt.
 
  Long term debt also includes a four (4) year term loan of US$ 291,000
(400,000 DM) by a private individual, former shareholder of German Subsidiary
and current minority shareholder of the Company. The loan was made to the
subsidiary on October 1, 1994 and with a repayment of principal and interest
to start at the end of April 1995. Interest was at a base rate of 5.25% plus
the prevailing German bank discount rate. Related party interest expense
incurred on this loan in 1996 amounts to $22,000 (34,000 DM). A portion of
this outstanding amount ((US$ 59,000) has been classified as a current
liability and represents an estimated twelve payments of principal. There were
principal payments of $58,000 during 1996 leaving a balance of $231,000 at
June 30, 1996. The lender did not require a security interest or collateral.
 
  On October 31, 1995, the Company completed a $1,500,000 Canadian dollar
($1.1 million US$) financing in the form of subordinated debt with C.I. C.P.A.
Business Ventures Fund, Inc., a venture capital fund of Covington Capital
Corporation. This subordinated debt has a term of five (5) years and an
interest rate of 12% per year, compounded monthly with interest payments only
in the first twelve (12) months. Principal payments of $6,250 Canadian dollars
will begin November 1996 through September 2000. This agreement includes a
first option for 250,000 shares of common stock at $1.25 per share for a term
of five (5) years, and a second option of 400,000 shares of common stock at
$2.50 per share until October 1996 and then at $3.25 per share until October
1997. The number of shares disclosed does not give effect to the Reverse Split
(Note G). Interest payments during fiscal 1996 amounted to $119,000 Canadian
dollars ($86,000 US). As of June 30, 1996, $37,000 has been classified as
short term debt and $1,063,000 as long term debt. The Company granted a
security interest in all of the Company's right, title and interest in all
accounts and proceeds. This collateral is subordinated to the bank debt.

NOTE F--INCOME TAXES
 
  At June 30, 1996 the Company has net operating loss carryforwards of
approximately $3,100,000 and $490,000 for U.S. federal and Canadian tax
reporting purposes, respectively, which expire in varying amounts through 2011
and 1999, respectively. In addition, the Company has approximately $161,000 of
net operating loss carryforwards for German tax reporting purposes and these
loss carryforwards do not have an expiration date. The Company also has a June
30, 1996, unused tax credits of approximately $116,000 and $71,000 for U.S.
federal and Canadian tax reporting, respectively, which expire in varying
amounts through 2003 and 1999, respectively, to offset future income taxes.
the tax credits primarily relate to research and development. As a result of
certain transactions involving issuance of the Company's common stock and
options to purchase stock, an "ownership" change occurred in 1988 under
Section 382 of the Internal Revenue Code of 1986. Consequently, future
utilization of the Company's U.S. net operating loss carry forwards and tax
credit carryforwards attributable to periods before the ownership change will
restrict the utilization of the loss carryforwards and tax credit
carryforwards in a particular year.
 
  The provision (benefit for income taxes consists of the following:

NOTE G--STOCK AND STOCK OPTIONS
 
  On June 21, 1996, prior to the Company's fiscal year end, the Company
amended its Restated and Amended Certificate of Incorporation to reflect a
reverse stock split whereby one (1) share of common stock was exchanged for
three (3) shares of common stock. This Reverse Split will impact all
authorized common stock and stock options including treasury shares, employee
and non-employee stock options. The weighted average shares outstanding are
computed on a Reverse Split and fully diluted basis.
 
  The Company adopted a Stock Option Plan ("Plan") in 1987 to provide

NOTE I--LEASES AND COMMITMENTS
 
  On November 20, 1989, the Company entered into a sale/leaseback agreement
with a leasing company. The Company sold certain demonstration inventory used
by the sales and marketing departments for $299,950 resulting in a $176,750
gain, which has been recognized over the lease term using the effective
interest rate method. The balance of the gain in the amount of $3,000 was
recognized in fiscal 1995. Under the terms of the agreement, the Company had
agreed to lease back the equipment under a noncancelable five year term.
 
  At the end of the lease term in December 1994, the Company had the option to
purchase the equipment at fair market value or extend the lease for a one-year
period. The Company negotiated a renewed lease for $35,000 to be paid over
eighteen (18) months at an interest rate of 10.25%. Payments under the
original capital lease obligation had an effective interest rate of 11.8
percent. The renewed capital lease contains a bargain purchase option and on
June 11, 1996, the Company exercised this bargain purchase option and
purchased the equipment for one (1) dollar.
 
  The Company entered into an agreement with New Court Credit Corporation in
March 1996 to finance a purchase of CNC milling machine for the Canadian plant
machine shop. The term loan amount was for $90,000 Canadian dollars ($66,000
US) for a period of 5.5 years and at an interest rate of 10.4%. This agreement
includes a purchase option for $9,000 Canadian dollars at the end of the fifth
year. Payment on principal through June 30, 1996 was $5,000 Canadian ($4,000
US). Interest payments for fiscal 1996 were $2,000 Canadian dollars.
The balance of debt at June 30, 1996 was $85,000 Canadian dollars ($62,000 US)
with $10,000 classified as the current portion of the long term debt.

NOTE L--GERMAN SUBSIDIARY
 
  On September 30, 1994, the Company established a new subsidiary (Photo Med
GmbH) in Hamburg, Germany. The Company owned 51% of the subsidiary at that
time, and three individual investors owned the remaining 49%. Subsequent to
the formation, the German Subsidiary entered into an agreement with the
Stadtparkasse Bank of Wedel, Germany. Under this agreement, the German
Subsidiary acquired certain inventory and fixed assets through the bank from
the Company's German distributor. In addition, the German Subsidiary agreed to
assume certain outstanding liabilities of the previous German distributor,
including outstanding payables to various vendors, unpaid compensation and
social costs of certain employees.
 
  This series of transactions was accounted for as a business combination
using the purchase method of accounting. Accordingly, the acquired assets and
liabilities were recorded at their estimated fair value at the date of
acquisition. The excess of purchase price over the net liabilities acquired
has been capitalized as goodwill, and will be amortized on a straight-line
basis over a five year period. The unamortized balance of goodwill is included
in "other assets".
 
  The purchase price of the 51% ownership, which comprised the assumption of
liabilities, was allocated as follows:

</TABLE>
 
  The operating results in fiscal 1995 of the German Subsidiary, subsequent to
September 30, 1994, were included in the Company's result of operations. The
minority interest's 49% share of the German Subsidiary's income was excluded
from the determination of net income of the Company in 1995.
 
  In fiscal 1996, the Company assumed an additional $43,000 of liabilities
with respect to the 51% acquisition of the German Subsidiary. This amount was
added to the goodwill balance.
 
  On July 5, 1995 of this fiscal year, the Company acquired the remaining 49%
ownership of the German Subsidiary from its minority shareholders. The Company
issued 150,000 common shares from treasury stock, at a value of $1 per share.
As a result of this transaction, the German Subsidiary became a wholly-owned
subsidiary of the Company. The transaction is accounted for as a business
combination (step-by-step acquisition) using the purchase method of
accounting.
 
  The purchase price for the remaining 49% ownership was allocated as follows:

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (IN US$)--(CONTINUED)
 
  The Company is exposed to credit losses in the event of non-performance by
the counter-parties to its financial assets, however, the Company does not
anticipate non-performance of such parties. There is no off-balance sheet
credit risk of accounting loss.
 
  Concentrations of credit risk could arise since a number of the Company's
customers are government agencies or academic institutions worldwide. However,
the Company does not foresee a credit risk associated with its receivables
primarily due to the fact that these customers are funded prior to the
purchase of products and overall the Company historically has had no material
bad debts. The allowance for doubtful accounts is adequate to provide for
normal credit losses.
 
NOTE P--SIGNIFICANT RISKS AND UNCERTAINTIES
 
  The preparation of the consolidated financial statements of the Company in
conformity with generally accepted accounting principles (GAAP) 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 periods ended June 30.
 
  Management does not anticipate a significant change in the estimates that
may affect the carrying amount of assets or liabilities or the disclosure of
loss contingencies in the near term.
 
  The Company's major products are electro-optical and light-based
instrumentation which utilizes fluorescence technology. The primary-market
served are medical life sciences, physical sciences, environmental and
industrial. The Company markets its products worldwide. Markets of particular
concentration include North America, Europe, South America and the Pacific
Rim. The Company's products are primarily used in research, diagnostics
testing, monitoring or process/quality control. The Company's customer base
includes universities, pharmaceutical companies, hospitals, biotechnology
companies and industrial companies. The Company has been in business and
serving these markets with products since 1983 and have established a solid
customer base which provide repeat and/or referral business. The products are
proprietary and patented. The products are very competitive and accepted due
to the technical properties of fluorescence such as sensitivity, which allows
detection of very small-subcellular amounts of substance with accuracy, non-
invasive and non-radioactive characteristic for safety, speed in monitoring
changes, visualization of images to monitor changes and relatively low cost.
Although there are competing technologies and competition in existing markets
for fluorescence technology, the Company does not appear to be materially
impacted or limited by this competition.
 
  With a solid customer base, a proven technology, markets which are growing,
a demonstrated need for the Company's products, and the ability to reduce
product costs, the Company does not feel there is a significant risk to future
sales growth. The Company intends to continue to invest in research and
development for new products and new product accessories. The Company intends
to continue to seek financing opportunities to meet these goals. However,
there can be no assurances that the Company will obtain the financing
opportunities and have the financial resources to support development effort,
sales and marketing of products and the proper internal management structure
worldwide.

          Thousand Fifty ($1,050) for each share of such preferred stock
          redeemed together with the amount of such accrued dividends as may
          have accumulated thereon at the time of redemption."

of the Corporation that were unissued prior to the share combination.

          This Certificate of Amendment has been executed on behalf of the
Corporation by its Vice President, Controller and Treasurer this 2nd day of May

     interest due on the Obligations and any other amounts owing by Borrower to
     Bank. Bank will notify Borrower of all debits which Bank makes against
     Borrower's accounts. Any such debits against Borrower's accounts in no way
     shall be deemed a set-off. Any interest not paid when due shall be
     compounded by becoming a part of the Obligations, and such interest shall
     thereafter accrue interest at the rate then applicable hereunder.

          (d)  Computation.  In the event the Prime Rate is changed from time 
               -----------   
     to time hereafter, the applicable rate of interest hereunder shall be
     increased or decreased effective as of 12:01 a.m. on the day the Prime Rate
     is changed, by an amount equal to such change in the Prime Rate. All

available federal funds or unless and until such check or other item of payment
is honored when presented for payment.  Notwithstanding anything to the contrary

Pacific time shall be deemed to have been received by Bank as of the opening of
business on the immediately following Business Day.  Whenever any payment to
Bank under the Loan Documents would otherwise be due (except by reason of
acceleration) on a date that is not a Business Day, such payment shall instead
be due on the next Business Day, and additional fees or interest, as the case
may be, shall accrue and be payable for the period of such extension.

     Agreement, or

          (b)  If Borrower fails or neglects to perform, keep, or observe any
     other material term, provision, condition, covenant, or agreement contained
     in this Agreement, in any of the Loan Documents, or in any other present or

     other term, provision, condition, covenant or agreement that can be cured,
     has failed to cure such default within twenty (20) days after Borrower

     the twenty (20) day period or cannot after diligent attempts by Borrower be
     cured within such twenty (20) day period, and such default is likely to be
     cured within a reasonable time, then Borrower shall have an additional
     reasonable period (which shall not in any case exceed thirty (30) days) to
     attempt to cure such default, and within such reasonable time period the
     failure to have cured such default shall not be deemed an Event of Default

change in the business, operations, or condition (financial or otherwise) of the
Borrower, or (ii) is a material impairment of the prospect of repayment of any

attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within ten (10) days, or if Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of Borrower's assets by the United States Government,
or any department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within ten (10) days
after Borrower receives notice thereof,
<PAGE>
 
                                     -24-

provided that none of the foregoing shall constitute an Event of Default where

good faith contest by Borrower (provided that no Advances will be required to be
made during such cure period);

Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced
against Borrower and is not dismissed or stayed within thirty (30) days
(provided that no Advances will be made prior to the dismissal of such
Insolvency Proceeding);

          8.6   Other Agreements.  If there is a default in any agreement to

such third party or parties, whether or not exercised, to accelerate the
maturity of any Indebtedness in an amount in excess of One Hundred Thousand
Dollars ($100,000) or that could have a Material Adverse Effect;

subordination agreement entered into with Bank;

          8.8   Judgments.  If a judgment or judgments for the payment of money
                ---------                                                      
in an amount, individually or in the aggregate, the uninsured portion of which
is  at least Fifty Thousand Dollars ($50,000), shall be rendered against
Borrower and shall remain unsatisfied and unstayed for a period of thirty (30)
days (provided that no Advances will be made prior to the satisfaction or stay

          8.9   Misrepresentations.  If any material misrepresentation or

          9.1   Rights and Remedies.  Upon the occurrence and during the

continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

          (a)   Declare all Obligations, whether evidenced by this Agreement, by
     any of the other Loan Documents, or otherwise, immediately due and payable
     (provided that upon the occurrence of an Event of Default described in
     Section all Obligations shall become immediately due and payable without
     any action by Bank);
<PAGE>
 
                                     -25-

          (b)  Cease advancing money or extending credit to or for the benefit
     of Borrower under this Agreement or under any other agreement between
     Borrower and Bank;

          (c)  Demand that Borrower (i) deposit cash with Bank in an amount
     equal to the amount of any Letters of Credit remaining undrawn, as
     collateral security for the repayment of any future drawings under such
     Letters of Credit, and Borrower shall forthwith deposit and pay such
     amounts, and (ii) pay in advance all Letters of Credit fees scheduled to be
     paid or payable over the remaining term of the Letters of Credit;

          (d)  Settle or adjust disputes and claims directly with account
     debtors for amounts, upon terms and in whatever order that Bank reasonably
     considers advisable;

          (e)  Without notice to or demand upon Borrower, make such payments and
     do such acts as Bank considers necessary or reasonable to protect its
     security interest in the Collateral. Borrower agrees to assemble the
     Collateral if Bank so requires, and to make the Collateral available to
     Bank as Bank may designate. Borrower authorizes Bank to enter the premises
     where the Collateral is located, to take and maintain possession of the
     Collateral, or any part of it, and to pay, purchase, contest, or compromise
     any encumbrance, charge, or lien which in Bank's determination appears to
     be prior or superior to its security interest and to pay all expenses
     incurred in connection therewith. With respect to any of Borrower's owned
     premises, Borrower hereby grants Bank a license to enter into possession of
     such premises and to occupy the same, without charge, for up to one hundred
     twenty (120) days in order to exercise any of Bank's rights or remedies
     provided herein, at law, in equity, or otherwise;

          (f)  Without notice to Borrower set off and apply to the Obligations

     Borrower held by Bank;

          (g)  Ship, reclaim, recover, store, finish, maintain, repair, prepare
     for sale, advertise for sale, and sell (in the manner provided for herein)
     the Collateral. Bank is hereby granted a license or other right, solely
     pursuant to the provisions of this Section , to use, without charge,
     Borrower's labels, patents, copyrights, rights of use of any name, trade
     secrets, trade names, trademarks, service marks, and advertising matter, or
     any property of a similar nature, as it pertains to the Collateral, in
     completing production of, advertising for sale, and selling any Collateral
     and, in connection with Bank's exercise of its rights under this Section ,
     Borrower's rights under all licenses and all franchise agreements shall
     inure to Bank's benefit;

          (h)  Sell the Collateral at either a public or private sale, or both,
     by way of one or more contracts or transactions, for cash or on terms, in
     such manner and at such places (including Borrower's premises) as Bank
     determines is commercially
<PAGE>
 
                                     -26-
     reasonable;

          (i)  Bank may credit bid and purchase at any public sale; and

          (j)  Any deficiency that exists after disposition of the Collateral as
     provided above will be paid immediately by Borrower.

          9.2  Power of Attorney.  Effective only upon the occurrence and during
               -----------------                                                
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section  regardless of whether an Event of Default has
occurred.  The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

          9.3  Accounts Collection.  At any time from the date of this
               -------------------                                    
Agreement, Bank may notify any Person owing funds to Borrower of Bank's security
interest in such funds and verify the amount of such Account, provided, however,
as long as no Event of Default has occurred and is continuing, any such
notification and verification by the Bank shall only be made upon three Business
Days' prior notice to Borrower.  Upon and during the continuance of an Event of
Default, Borrower shall collect all amounts owing to Borrower for Bank, receive
in trust all payments as Bank's trustee, and immediately deliver such payments
to Bank in their original form as received from the account debtor, with proper
endorsements for deposit.

          9.4  Bank Expenses.  If Borrower fails to pay any amounts or furnish
               -------------                                                  
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following:
(a) make payment of the same or any part thereof; (b) set up such reserves under
the Committed Revolving Line as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance policies
of the type discussed in Section  of this Agreement, and take any action with
respect to such policies as Bank deems prudent.  Any amounts so paid or
deposited by Bank shall constitute Bank Expenses, shall be immediately due and
payable, and shall bear interest at the then applicable rate hereinabove
provided, and shall be secured by
<PAGE>
 
                                     -27-

the Collateral.  Any payments made by Bank shall not constitute an agreement by
Bank to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

          9.5  Bank's Liability for Collateral.  So long as Bank complies with
               -------------------------------                                
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for:  (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever.  All risk
of loss, damage or destruction of the Collateral shall be borne by Borrower.

          9.6  Remedies Cumulative.  Bank's rights and remedies under this
               -------------------                                        
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity.  No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver.  No delay by
Bank shall constitute a waiver, election, or acquiescence by it.  No waiver by
Bank shall be effective unless made in a written document signed on behalf of
Bank and then shall be effective only in the specific instance and for the
specific purpose for which it was given.

          9.7  Demand; Protest.  Borrower waives demand, protest, notice of
               ---------------                                             
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and

present or prospective business relations with Borrower, (ii) to prospective

in connection with the examination, audit or similar investigation of Bank.
Confidential information hereunder shall not include information that either:
(a) is in the public domain or in the knowledge or possession of Bank when
disclosed to Bank, or becomes part of the public domain after disclosure to Bank
through no fault of Bank; or (b) is disclosed to Bank by a third party, provided
Bank does not have actual knowledge that such third party is prohibited from
disclosing such information.

Rate (as defined below) plus 1.5% until the Maturity Date, payable monthly in

Bank at any given time).

     Computations of interest shall be made by the Bank on the basis of a year
of 360 days for the actual number of days occurring in the period for which such
interest is payable.

                         AGREEMENT TO PROVIDE INSURANCE


GRANTOR:  Photon Technology International, Inc.     BANK:  Silicon Valley Bank

- --------------------------------------------------------------------------------

     INSURANCE REQUIREMENTS.  Photon Technology International, Inc. ("Grantor")
understands that insurance coverage is required in connection with the extending
of a loan or the providing of other financial accommodations to Grantor by Bank.
These requirements are set forth in the Loan Documents.  The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

          Collateral:    All Inventory, Equipment and Fixtures.
          Type:          All risks, including fire, theft and liability.
          Amount:        Full insurable value.
          Basis:         Replacement value.
          Endorsements:         Loss payable clause to Bank with stipulation
                                that coverage will not be canceled or diminished
                                without a minimum of twenty (20) days' prior
                                written notice to Bank.

     INSURANCE COMPANY.  Grantor may obtain insurance from any insurance company
Grantor may choose that is reasonably acceptable to Bank.  Grantor understands
that credit may not be denied solely because insurance was not purchased through
Bank.

     FAILURE TO PROVIDE INSURANCE.  Grantor agrees to deliver to Bank, on or
before closing, evidence of the required insurance as provided above, with an
effective date of June 26, 1996, or earlier.  Grantor acknowledges and agrees
that if Grantor fails to provide any required insurance or fails to continue
such insurance in force, Bank may do so at Grantor's expense as provided in the
Loan and Security Agreement.  The cost of such insurance, at the option of Bank,
shall be payable on demand or shall be added to the indebtedness as provided in
the security document.  GRANTOR ACKNOWLEDGES THAT IF BANK SO PURCHASES ANY SUCH
INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION AGAINST PHYSICAL DAMAGE
TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN; HOWEVER, GRANTOR'S EQUITY IN
THE COLLATERAL MAY NOT BE INSURED.  IN ADDITION, THE INSURANCE MAY NOT PROVIDE
ANY PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION AND MAY NOT MEET THE
REQUIREMENTS OF ANY FINANCIAL RESPONSIBILITY LAWS.

     AUTHORIZATION.  For purposes of insurance coverage on the Collateral,
Grantor authorizes Bank to provide to any person (including any insurance agent
or company) all information Bank deems appropriate, whether regarding the
Collateral, the loan or other financial accommodations, or both.
