Item 1.     BUSINESS

General

Photon Technology International,  Inc. (the "Company" or "PTI(") is a New Jersey
based high technology corporation, incorporated in November 1983. PTI is engaged
in  the  business  of  exploiting  the  many  applications  of  the  proprietary
fluorescence technology that it has developed.

Fluorescence  is a  relatively  new  technique  that offers the  following  user
benefits:

         o  sensitivity - can detect  10,000,000  times smaller  quantities than
            conventional techniques

         o  speed  -  can  detect  1,000,000  times  faster  than   conventional
            techniques

         o  universal - some substances  fluoresce directly,  others can be made
            to  fluoresce,  by means of  fluorescence  dyes that are specific to
            that substance

         o  safe  and can be used in  vitro - the only  competing  technique  is
            radio active labeled substances, obviously much less desirable.

          ocost competitive

Fluorescence is used to:

         o  measure  minute  amount of  substances  - can  detect  much  smaller
            quantities than by any other means

         o  measure changes in substances over time - the time can be very short

         o  show where  substances  of  interest  are  located - can be visually
            observed through a microscope trace where substances are migrating

Examples of fluorescence applications are:

         o  environmental  studies - how much  pollutant;  where is it  located;
            where does it originate

         o  pharmaceutical studies - drug affects

         o  process control - impurities, contaminants

         o  medical - detection of diseases in early stages, such as:
                      cancer, Alzheimer's, heart, kidneys,           
                      nervous disorders - diagnostic                 
                    - causes of diseases - research                  
                    - reaction and monitoring of treatment           
            
         o agriculture

         o  foods -  detection  of bacteria  and  contaminants,  measurement  of
            freshness

Fluorescence  applications  are  growing,  and can be found in  virtually  every
field,   where  the  detection  and  monitoring  of  minute   substances  is  of
significance.

PTI has developed a full line of proprietary and/or patented  fluorescence based
instrumentation  to serve as a  platform  for the  exploitation  of this  useful
technique.

PTI's head offices are located in Monmouth  Junction  New Jersey.  PTI sells its
products in North America through a direct sales force, located in six different
sales offices in the U.S. and Canada.

In June of 1987,  the Company  incorporated  a wholly owned  subsidiary,  Photon
Technology International (Canada) Inc., located in London, Ontario, Canada ("PTI
Canada").   PTI  Canada's   operations  include   manufacturing,   research  and
development,  engineering and product  support.  PTI Canada serves as one of the
Company's primary manufacturing sites.

European sales, service,  distributors and product distribution are managed from
offices located in London England,  through an  unincorporated  branch office of
the  Company  (PTI  UK).  In  September  of 1994,  PTI  established  a 51% owned
subsidiary,  PhotoMed  GmbH in Wedel,  Germany,  to handle  sales and service in
Germany, Austria, Benelux and Scandinavia, through a direct sales force. In July
of 1995, PTI acquired 100% of the subsidiary.

In April of 1987,  the  Company  entered  into a  research  agreement  with M.L.
Technology  Ventures L.P. ("MLTV") to develop four different  products.  PTI has
successfully completed the products under the agreement.  MLTV's interest in the
products  have been  taken over by PTI in  exchange  for  333,333  shares of the
Company in December 1995.

The  Company  is  focused  on  the  fluorescence   market  place.  PTI  believes
fluorescence is a multi-billion dollar market,  enjoying substantial growth. PTI
has the ability to identify commercial and scientific  applications  through its
technical and design capability and to provide products which "add value" to the
end users and which are  responsive  to these needs.  This ability is key to the
Company's  success.  The  Company's  know-how that is employed in its design and
assembly  techniques results in competitive  products which have high precision,
quality and lower cost.


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  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 are 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 the 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, 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 in the  industry  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  a  powerful  and  rapidly  expanding  tool  for  cellular  and
sub-cellular testing because it is:

         o  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.

         o  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).

         o  faster than other means - it can monitor changes in trillionths of a
            second, or about 1,000,000 times faster than other techniques.

         o  a visual process - microscopic images can be gathered and displayed,
            for example, showing changes inside living cells.

         o  less  expensive  than other  techniques,  which means it can do more
            work for less money, while saving time, resources and even lives.


Products

PTI initially  developed a line of proprietary  and/or patented optical building
blocks  ("OBB's") which form the basis of all light based  instrumentation.  The
Company sells these building  blocks as stand alone units.  In addition PTI uses
these  unique  building  blocks to develop  its open  architecture  fluorescence
systems. The open architecture offers the benefits of:

         o  more versatile equipment - more options

         o  customers  can buy  upgrades  and  options  as they need them or can
            afford them

         o  less time for development of new systems - PTI can more rapidly meet
            new market demands

         o  less chance of product obsolescence

         o  lower costs

PTI at the start of the 1998F year has  reorganized its product line, into seven
product lines.

Product Group I - Optical Building Blocks

PTI's  components make up this line. They are composed of: light sources,  light
and sampling  handling  modules and various  detectors.  This product line has a
very broad market,  since these modules can be used wherever light is used. They
also have significant  O.E.M.  applications.  This product line is PTI's oldest.
The products have been totally  redesigned and kept up to the latest  technology
and specifications.

Product Group II - Intensified Cameras

PTI's  newest  product  group was  developed  only two years  ago.  The line was
expanded in 1997F, with two new cameras added to the line.  Intensified cameras,
or  ICCD's,  are  cameras  that are very  similar  in the  basic  technology  to
camcorders  except that they use an intensifier that allows these cameras to see
under very low light  levels.  These  cameras  were  originally  used by PTI for
fluorescence  applications.  PTI decided to develop  these  cameras to lower the
costs. Formerly such cameras cost more than $15,000, PTI's cameras were designed
to offer virtually the same benefits, for $6,000. This has opened up a whole new
line of  applications  for such cameras in:  machine  vision,  surveillance  and
military applications, just to name a few.

Most of the new  applications  use the  camera  as a  detection  component  of a
system. Therefore the sales will be to O.E.M.'s.

Product Group III - Microscope Accessories

PTI has had to develop specialized  building blocks for use with microscopes for
its systems.  Prior to the 1998F year,  PTI has not offered these  components as
individual  units.  They were sold  exclusively  in PTI's  systems.  By  popular
demand, PTI has elected to offer these units as components in a separate product
line, since the market for such products is different from the OBB line.

The product line contains microscope illuminators and detectors that can be used
with most of the popular manufactured microscopes.

Product Group IV - Ratio-Fluorescence Systems (excluding imaging) - RatioMaster

This is PTI's first  systems line,  introduced in 1987.  The line is composed of
systems  that  can  detect  various  ions,  or  fluorescent  labeled  compounds,
generally found in living organisms.  These have a wide range of applications in
the medical,  life science and pharmaceutical areas. They are currently used for
research  applications  to  diagnose  diseases,  monitor  drug  effects,  or  to
understand  various  functions of living  organisms.  The systems can be used to
study, in-vivo:
tissues, cells, single cells or even events happening at sub-cellular levels.

PTI is well  recognized  as a  scientific  leader in this  field.  The  recently
introduced RAM  technology  (patent  pending),  developed with the MLTV funding,
once again makes PTI a technological leader in this area.

Product Group V - Fluorescence Imaging Systems - ImageMaster

Initially,  these imaging systems were used with PTI's  Ratio-Fluorescence line.
Imaging gives the added dimension of spatial resolution. Not only can one detect
and measure substances, but one can also tell where they are - or if they are on
the move - where they are moving.  Because the technology is much different from
ratio-fluorescence and because there are new applications that are developing in
other areas, fluorescence imaging has been set up as a separate product line.

The RAM  technology  is also being used in the imaging  area to give the product
unique advantages.

Product Group VI - Steady State Fluorescence - QuantaMaster

PTI has recently  entered the largest  single market in the  fluorescence  area.
Steady  state  fluorimeters  are used in most  basic  fluorescence  applications
wherever one has to detect small amount of substances,  such as:  environmental,
pharmaceutical, chemical, medical and process control.

PTI's modular  architecture and price is unique in this market.  PTI had not had
the necessary financial resources to properly promote this product. With the new
financing in 1997, (refer to Note I in Financial Statements) PTI will place more
emphasis on this product line.

Product Group VII - Fluorescence Life-Time Systems - TimeMaster

TimeMaster( 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(    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(  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( uses a NanoFlash( illuminator source.

LaserStrobe(  is  based  on the  strobe  technique  for  measuring  fluorescence
lifetimes  and is as  unique as the  StrobeMaster(.  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(  and  LaserStrobe(,  has started to be recognized and accepted for
measuring  fluorescence  lifetimes as evidenced by sales of these systems during
fiscal 1996.


Sales and Marketing

PTI  reorganized  its product line and its sales force at the start of the 1998F
year.  Prior to this time PTI used product  specialists to sell the entire line.
Now selected  product  specialists  sell individual  product lines.  PTI expects
better  sales  coverage  and  a  more  competitive   sales  force  through  this
reorganization.

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.

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 North American 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.

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;  San Diego,  California;  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.  Distributor  coverage is being expanded
in 1998F.


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 are  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 the OBB product  line,  the  Company  competes  with  catalogue
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.


Proprietary Rights

PTI is a registered  trademark of the Company. In addition:  FeliX,  TimeMaster,
QuantaMaster,   RatioMaster,   Deltascan,   PowerArc,   PowerFilter,   DeltaRam,
ImageMaster are registered.  The Company  endeavors to maintain its know-how and
technologies  as trade secrets.  The Company has one U.S.  patent on each of the
current  Deltascan(,  RatioMaster(  and the  TimeMaster(  Fluorescence  Lifetime
systems,  with expiration dates ranging from 2005 to 2007. The Company has filed
for patent  protection on the RAM  technology.  The Company also relies on trade
secrets  and  proprietary  know-how.  There can be no  assurance  that the trade
secret or propriety  nature of such  information will not wrongfully be breached
by  employees,  consultants,  advisors or others,  or that the  Company's  trade
secrets  or  propriety   know-how  will  not   otherwise   become  known  or  be
independently  developed by competitors in such a manner that the Company has no
practical recourse.


Research and Development

PTI believes that its key strength is its product research. In 1997, the Company
spent $878,425  (1996-$844,403)  or more than 10% (1996-9%) of total revenues on
research and development.  This is above the average by other companies in PTI's
industry.  PTI not only spends  monies for  developing  new products but is also
coming up with new ways to decrease  costs while  maintaining  or even improving
existing products performance.

Research and development was in four primary areas in the last two years:

         Cost Reduction

PTI has invested a substantial  amount of monies in the reduction of the product
costs.  The  results  have  allowed the  Company to reduce  prices,  while still
increasing  margins and improving  product  performance.  PTI believes that cost
benefit  analysis  will  increasingly  be a factor  in the  purchasing  decision
process.  By  investing in this type of research it will help PTI to become more
competitive.

An  excellent  example of this  research is the ICCD  camera  line which,  while
offering very  competitive  performance,  costs half of existing  products being
offered for sale in the market place.

         Software

Particularly  for systems,  an important  selling  feature is the software  that
controls the product and helps in analyzing  the  results.  With the  constantly
changing computers and operating  systems,  software research has become a major
expense in research.

Given the scarcity of software personnel,  PTI has been particularly  successful
in recruiting  off-shore  talent to meet the Company's  growing  software  skill
needs.

         The RAM Project

The Company has invested heavily in the  commercialization of products developed
under  the RAM  technology  that was  developed  with the MLTV  financing.  This
technology  offers a lot of unique  benefits  that will be utilized in virtually
all of the  current  systems  lines and will also  lead to new  products  in the
future. PTI has applied to patent the RAM technology.  Currently, the Company is
already   successfully  using  one  of  the  products  in  the  RatioMaster  and
ImageMaster systems lines.

         EC Compliance

About two years ago, the European  Economic  Community  introduced new rules for
electronic products.  Since virtually all of our products have some electronics,
we have had to test all  products  and make  modifications  that allowed them to
pass this test.  Currently  all of our products  comply with the new  standards.
This has been a major and costly undertaking.  PTI will attempt to recover these
costs by charging  higher  prices in Europe.  PTI  believes  that a  significant
number of its smaller competitors did not bother to comply. This should give PTI
a competitive advantage and may even reduce the competition.


Backlog

The Company's  backlog  consists of orders  scheduled for delivery  within three
months.  As of June 30, 1997, the Company  backlog was  $1,362,000,  as compared
with $1,087,000 as of June 30, 1996.


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 Monmouth  Junction,  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 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

     Distribution Agreement-Germany

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 provides 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.

     Corporate Alliance with Otsuka Electronics Co., Ltd. Japan

In August of 1997, PTI signed a distribution  agreement with Otsuka  Electronics
Co.,  Ltd.  ("Otsuka"),  to sell the  Company's  products in Japan.  Otsuka is a
wholly owned subsidiary of Otsuka Pharmaceutical Co Ltd of Japan.

     Distribution Agreement for Lasers

In August of 1997, PTI signed a distribution  agreement with LTB Lasertechnik in
Berlin GmbH ("LTB") for a line of nitrogen and dye lasers. PTI currently makes a
nitrogen and dye laser product.  The LTB lasers should be complementary and help
to complete the Company's product line.

     $2,000,000 Financing

In March of 1997,  PTI raised $2 million of financing  from C. I. Covington Fund
Inc. The financing  will allow PTI to finance its future growth plans.  For more
detail refer to Note I in Financial Statements.

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         Results of Operations

FISCAL YEAR 1997 COMPARED TO FISCAL YEAR 1996

Total revenue of $8,401,786 in 1997 decreased by $857,014 or 9% from  $9,258,800
in 1996.  The decrease in revenue was  primarily  due to a decrease in orders in
the first half of the year, due to resources  being directed  towards  obtaining
financing and completing  research and development  projects.  During the second
half of the year, when financing was assured, orders caught up the first half of
the year.

Cost of  product  sold of  $3,385,717  for 1997  decreased  in  dollar  terms by
$270,193 or 7.4% in  comparison  to cost of sales of  $3,655,910  in 1996.  On a
percentage  of net sales basis,  cost of products sold  increased  from 39.5% to
40.3% for the same comparative period. The dollar cost decrease in cost of sales
related to the decrease in sales  volume.  The  increase as a percentage  of net
sales reflects the additional one time product cost increases to meet EC rules.

Selling,  general and  administrative  expenses of $3,944,653 in 1997  decreased
$181,759 or 4.4% over  $4,126,412  in 1996.  The decrease  reflected the reduced
spending on sales promotion as resources were diverted for financing, meeting EC
regulations and research and development.  On a percentage sales basis, selling,
general and  administrative  expenses  increased  from 44.6% in 1996 to 46.9% in
1997.  This  increase in  percentage  is due to the  decrease in sales while the
expenses  were  maintained  at a  higher  level  in order to be able to react to
anticipated financing.

Research and development expenditures of $878,425 or 10.5% of net sales in 1997,
increased  from  $844,403  or 9.2% of net sales in 1996.  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.  Despite the lower
sales  PTI  actually   increased  its  research  and   development   efforts  in
anticipation of the financing.

Interest expense increased by $38,257 or 13.6% from $280,364 in 1996 to $318,621
in 1997. This increase  primarily relates to interest on incremental  short-term
borrowings on the credit facilities with the Company's lenders.

Depreciation  and  amortization  increased  from $150,370 in 1996 to $158,843 in
1997. This increase represents increase in property and equipment of $54,000.

There was no material change in goodwill  amortization,  which represents is the
goodwill amortization of the German Company's acquisition.

There was a loss of  $3,377  in  foreign  exchange  for  1997,  versus a gain of
$34,293 in 1996.  This is primarily due to the rise in the U.S.  dollar  against
the German mark.

Deferred tax benefit  increased  to $167,000 in 1997 from  $63,000 in 1996.  For
further explanation refer to Note G to the Financial Statements.

As a result of the foregoing, the Company reported a net loss for fiscal 1997 of
$274,161  in  comparison  to a net income of  $145,503  in 1996,  a decrease  of
$419,664.

As a result of this net loss  performance,  the net loss per  Common  Share on a
weighted average number of common  outstanding  shares was ($0.24) in comparison
to net income of $0.14 per share in 1996


FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995

Total  revenue  of  $9,259,000  in  1996  increased  $1,411,000  in  18.0%  from
$7,848,000 in 1995.

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
39.5% 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 44.6% 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.  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 of 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 G).

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  treasury  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 $0.14 in comparison to $0.47 per
share in 1995.  The earnings per share were  impacted by the dilution  effect of
one cent  ($.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.

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, 1997 was  $2,402,388 as compared
to $1,562,626 at June 30, 1996, an increase of $839,762 or 53.7%.

Current assets of $5,833,770  increased $1,173,073 or 25.2% in comparison to the
prior  year.  This  change  primarily  reflects  (a)  an  increase  in  cash  of
$1,088,662, (b) a decrease in trade accounts receivable of $166,110 or 7.4%, (c)
an increase in inventory of $168,535 or 8.9% and an increase in prepaid expenses
and other current assets of $81,986.  The net increase in cash was primarily due
to financing  activities.  The dollar decrease in trade receivables  reflect the
better  collection  of  accounts  receivable,  due to  the  fact  that a  larger
percentage of sales was U.S.  based,  which is generally  faster to collect than
foreign   receivables.   The  accounts  receivable  balance  of  $  2.1  million
represented  3 months of sales in comparison to 2.8 months of sales in the prior
year. The increase in months of sales reflects the higher level of sales in June
1977.

The inventory balance of $2.1 million  represents 7.3 months of sales,  compared
with 6.2 months in the prior year. The change in inventory primarily reflected a
build-up of long lead time items for new products for the next fiscal year.

Current  liabilities of $3,431,382  increased $333,311 or 10.8% in comparison to
the prior year. This was primarily due to: (a) net decrease in bank indebtedness
on short term credit  facilities  of $200,568  or 13.2%,  (b)  increase in trade
accounts  payable of $97,000 or 10%  primarily  due to higher  purchases of long
lead items for new product  launches and (c) increase in the current  portion of
the long term debt by  $464,781,  which  reflects  the MLTV  promissory  note of
$631,000 and regular  principal  payments on the remaining  debt coming due. The
Company  believes  that  there  is a  possibility  that  the  MLTV  loan  can be
refinanced.  In case that the MLTV loan may not be  refinanced,  the Company can
pay off the loan, but it would be a serious drain on its financial resources and
could hamper growth.

The Company owes the Silicon  Valley Bank  $1,066,615  on a  $2,000,000  working
capital  line of credit.  The line of credit has been  extended  to October  15,
1997. The company has paid back the inventory  sub-limit advance as of September
15, 1997.  The Company  believes that the line of credit will be extended  after
the October 15 date.

Bank indebtedness includes the line of credit with the German Stadtparkasse Bank
to  support  the German  Subsidiary  operations.  The  outstanding  balance  was
$255,214 (445,478 DM) on June 30, 1997, on a line of credit of $285,714 (500,000
DM).

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
was due at the end of the two year term.  As of June 30,  1997,  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
occurs under the terms of the agreement. MLTV agreed to defer payments from June
1996 through July 1997. The deferred amount is subject to interest in accordance
with the agreement.

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 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.  Payments  of  principal  commenced  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.

In July 1994,  documents were fully  executed  between the "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. The
balance  outstanding  as of June 30,  1997 on the ODC  fixed  loan was  $299,992
Canadian  dollars  ($217,224  US) based on specific  advance  requests  approved
through  this date.  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 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.

In the 1996 fiscal year, the Company did not have sufficient financial resources
to finance  growth,  research and  development  and complete EC compliance.  PTI
elected to  sacrifice  temporarily  the  financing  of the  growth,  in order to
complete its  research and  development  plans and the EC  compliance,  since it
believed  that it was the best road to  follow  if it was  going to raise  funds
necessary to continue its growth.

On March 7, 1997, PTI raised its first significant  equity financing since 1987,
for $2,000,000, net $1,962,137 (for detail on specific terms, refer to Note I to
the Financial Statement). The importance of this financing is that it allows the
Company to pursue its growth  goals.  The Company will use the financing for new
product introduction and to expand its sales and marketing coverage.

The major  risk is the  timing of sales  following  the  promotional  campaigns.
Generally  there is a six month sales  cycle,  but the sales cycles can lengthen
due to economic conditions. Should the sales cycle become too long, PTI does not
have the financial  resources to sustain the sales and marketing plans and would
have to cut back on its marketing and sales efforts.

If the Company has to repay some of the short term maturing  debt, it will loose
a  substantial  portion of its  financial  resources to pursue its growth plans.
Whereas  there is every  reason to believe  that the Company can  refinance  its
maturing debt, there is no guarantee that it will be able to do so.

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 continue to seek additional
financing to fully exploit its sales and marketing potential. 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.

Section 16(a) Beneficial Ownership Reporting Compliance

(1)      All options  granted to Named  Executive  Officers are incentive  stock
         options  under the federal tax laws and were  granted on June 27, 1997.
         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.

(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 Named  Executive  Officer or any
         other holder of the  Company's  securities  that the actual stock price
         appreciation  over the 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 Named Executive Officer.

                          FISCAL YEAR-END OPTION VALUES

The  following  table sets forth  information  regarding the number and value of

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,  1997 the  Company  paid an  aggregate  of $5,000  for  director
traveling expenses.  In addition,  each non-employee director received an option
grant to purchase  3,333 shares of Common Stock on December 8, 1996 at an option
price of $1.31 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, 1997, 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
$215,000 in 1997.  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 Named  Executive  Officer 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 option agreements the outstanding 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  333,333 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 Named  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


Item 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND
           MANAGEMENT

The following table sets forth as of September 1, 1997, information with respect
to (a) each  person  (including  any  "group"  as that  term is used in  section
13(d)(3) of the Securities  Exchange Act of 1934) who is known to the Company to
be the beneficial owner of more than five percent (5%) of the outstanding Common
Stock of the Company and (b) the number and  percentage of the Company's  Common
Stock owned by (i) each of the directors and the executive officers named on the
Summary  Compensation  Table above and (ii) all directors and executive officers
of  the  Company  as a  group.  The  Company  believes  that,  unless  otherwise
indicated,  each of the  shareholders  has sole voting and investment power with
respect to the shares beneficially owned.

                         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,  1997 and 1996,  and the related
consolidated statements of operations,  shareholders' equity, and cash flows for
each of the three  years in the period  ended  June 30,  1997.  Our audits  also
included the financial  statement  schedule listed in the index at item 14(a) of
Form 10-K. 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 audits 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 audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the consolidated financial position of Photon Technology
International,  Inc. at June 30, 1997 and 1996, and the consolidated  results of
its  operations  and its cash  flows for each of the three  years in the  period
ended June 30, 1997, 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.

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  utilize  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 O), its sales  office  branch in the United
     Kingdom,  and  a  domestic  joint  venture  in  which  the  Company  had  a
     controlling interest through December 8, 1995 (see Note B). All significant
     intercompany transactions and balances are eliminated on 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  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  and highly  liquid  debt
     instruments with a maturity at acquisition of three 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 lives 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.

6.   Other Assets

     Software  development costs are capitalized in accordance with the guidance
     of Statement of  Financial  Accounting  Standards  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  subsidiary  (German  Subsidiary),  and the  related  value of net
     assets   acquired  or  net   liabilities   assumed,   is  reported  net  of
     amortization,  and is amortized using the straight-line  method over a five
     year period.

     Technology  rights  acquired  through  issuance of the Company's  shares of
     common  stock  are  valued  at the bid  price  of the  stock at the date of
     transaction. These technology rights are being amortized on a straight-line
     basis over a ten year term.

     Direct  costs  related  to  financing  are  deferred  and  amortized  on  a
     straight-line basis over the term of the related financing agreement.

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--Continued

     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  flows to the  carrying  value  and
     reviewing other relevant factors that may affect carrying value. The amount
     of impairment,  if any, is measured based on discounted projected cash flow
     compared to the 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.

8.   Income Taxes

     The liability method under Statement of Financial  Accounting Standards No.
     109,  "Accounting  for Income  Taxes," is  utilized  to account  for income
     taxes.  Under  this  method,   deferred  tax  assets  and  liabilities  are
     recognized  for  temporary  differences  between  the  financial  statement
     carrying amount and the tax basis of the respective  assets and liabilities
     at the enacted tax rates.

9.   Net Income (Loss) Per Common Share and Common Share Equivalents

     Net income (loss) per common share and common share equivalents is computed
     on the basis of the  weighted  average  number of common  shares and common
     share  equivalents  outstanding.  For the years  presented,  the  effect of
     common stock  equivalents  arising  from stock  options was not included as
     they were anti-dilutive using the treasury method.

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 M.L.  Technology  Ventures,  L.P. ("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  333,333 shares of common stock to purchase the
technology  rights and related joint venture interest of the products  developed
under the Research and Development  Agreement  between the Company and MLTV. The
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 on the day of
the transaction,  which in management's opinion is the most objective measure of
the value of the  technology  rights.  As a result of the  agreement,  the joint
venture between the Company and MLTV terminated.

NOTE D--BANK INDEBTEDNESS--Continued

On June 26,  1996 the  Company  secured a working  capital  line of credit  with
Silicon Valley Bank for $2,000,000, from which the Bank of Montreal facility was
repaid in full. This credit  facility,  which had an original term expiring June
25,  1997,  has been  extended to October  15, 1997 and bears  interest at prime
(8.5% at June 30, 1997) plus 1.5%. 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 the United Kingdom branch office. The Company retains ownership
of intellectual property and is restricted on the pledge of this property to any
other party.  The  advances  are based on 75% of eligible  domestic and Canadian
accounts  receivable  due within ninety days of invoice date and 90% of eligible
foreign accounts  receivable that are covered  (supported) by either: (a) credit
insurance; or (b) letters of credit.

Effective  November 27, 1996, the facility with Silicon Valley Bank was modified
to establish inventory sublimit advances, up to a maximum of $300,000.  Interest
on the inventory sublimit advances is due and payable monthly and bears interest
at prime (8.5% at June 30, 1997) plus 2.0%. This modification included a warrant
to Silicon Valley Bank for the purchase of 5,000 common shares at $3.75 expiring
November 26, 2001. Also as part of this  modification,  MLTV agreed to defer the
principal repayment requirements on its subordinated promissory note (Note E).

Effective  June 10, 1997,  the terms of  repayment  for the  inventory  sublimit
advances  were  modified   requiring  the  Company  to  make  monthly  principal
repayments such that the balance outstanding would be repaid in full,  including
accrued  interest,  on September 15, 1997. The Company has received from Silicon
Valley Bank a waiver of covenant breaches at June 30, 1997.

Bank indebtedness includes the outstanding balance of 255,214 (445,478 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 O). The collateral for the
line  represents  a security  interest in all assets of the Germany  Subsidiary.
Interest  is charged on a quarterly  basis at rates based on the German  Federal
Bank's discount rate (8.75% at June 30, 1997).

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  was in the amount of $20,000 per month,  with the
remaining  balance to be paid in full at the end of this term.  In June 1996, as
part of the Company  obtaining its facility  with Silicon  Valley Bank (Note D),
MLTV agreed to defer the monthly  payments on the promissory note for the period
from June 1996  through  June 1997,  and to extend the  maturity  of the note to
December 1, 1997.  Interest accrues on the deferred  amounts  ($260,000) at 12%.
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 with Silicon  Valley Bank of California  (Note D) and ranks equally in
priority with the Covington Capital Corporation promissory note.

NOTE E--LONG TERM DEBT--Continued

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 an 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
Canada 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.
Repayments  began on July 15,  1996 for an amended  period of forty  months at a
rate  of  $11,597  Canadian  ($8,500  US) per  month,  including  principal  and
interest.  Interest  has been  charged  on a monthly  basis at a stated  rate of
6.75%,  effective since July 1994. 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 Silicon Valley Bank debt (Note D).

Long term debt also  includes an unsecured  loan by a private  individual to the
Company's  wholly-owned  German  subsidiary.   Blended  principal  and  interest
payments of 10,000  German  marks per month are  required.  Interest  accrues at
5.25% plus the prevailing  German Federal Bank's discount rate (2.5% at June 30,
1997).

On October 31, 1995, the Company completed a $1,500,000 Canadian ($1,100,000 US)
financing  agreement 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 years and bears  interest at 12% per
annum,  compounded monthly.  Principal payments of $6,250 Canadian monthly began
November 1996 and will extend through September 2000. This agreement  includes a
first option for 83,333 shares of common stock of the Company at $3.75 per share
for a term of five years  (expires  October 31,  2000),  and a second  option of
133,333  shares of common stock of the Company at $7.50 per share until  October
1996 and then at $9.75 per share until  October 1997.  In  conjunction  with the
issuance of preference shares of Photon Technology  International (Canada), Inc.
on March 7, 1997 (Note I), the option agreement  between C.I. - C.P.A.  Business
Ventures Fund,  Inc.,  and the Company was amended.  The number of second option
shares was  increased  by an  additional  50,000  shares of common  stock of the
Company at $9.00 per share. The total number of second option shares is 183,333,
and the option for all such second  option  shares was  extended by  twenty-four
months to October 31, 1999.  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 with Silicon Valley Bank and ranks
equally in priority with the subordinated promissory note payable to MLTV.

NOTE G--INCOME TAXES

At  June  30,  1997  the  Company  has  net  operating  loss   carryforwards  of
approximately  $3,000,000  and  $500,000  for  U.S.  federal  and  Canadian  tax
reporting purposes,  respectively,  which expire in varying amounts through 2012
and 1999,  respectively.  In addition, the Company has approximately $400,000 of
net operating loss  carryforwards for German tax reporting  purposes,  and these
loss  carryforwards do not have an expiration date. The Company also has at June
30,  1997,  unused tax credits of  approximately  $117,000  and $64,000 for U.S.
federal and  Canadian  tax  reporting  purposes,  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 U.S. 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 for the years ended June 30,  consists
of the following:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--Continued (in US$)

NOTE G--INCOME TAXES--Continued

Undistributed  earnings of the Company's foreign  subsidiaries are considered to
be indefinitely  reinvested,  and, accordingly,  no provision for US federal and
state  income  taxes  has been  provided  thereon.  Upon  distribution  of those
earnings in the form of dividends or otherwise,  the Company would be subject to
both U.S.  income taxes  (subject to an adjustment  for foreign tax credits) and
withholding taxes payable to the various foreign countries. Determination of the
amount of  unrecognized  deferred U.S.  income tax liability is not  practicable
because  of the  complexities  associated  with  its  hypothetical  calculation;
however,  unrecognized  foreign tax credit  carryforwards  would be available to
reduce some portion of the U.S. liability.

NOTE H--EMPLOYEE STOCK PURCHASE PLAN

The Company adopted an Employee Stock Purchase Plan, effective April 1, 1996, to
provide  eligible  employees of the Company  (including  the Canadian and German
subsidiaries)  with the  opportunity  to acquire a  proprietary  interest in the
Company.  The number of authorized  shares  reserved for issuance is 83,334.  In
1997, 5,958 shares were issued (no shares were issued during 1996).

NOTE I--PREFERENCE SHARES--Canadian Subsidiary

On March 7, 1997, 296,296  preference shares of Photon Technology  International
(Canada)  Inc.,  (a  wholly-owned   subsidiary)  were  issued.  The  shares  are
non-voting, non-cumulative,  non-redeemable, retractable, non-participating, and
without  nominal or par value.  The aggregated  purchase price of the preference
shares was US$ 2,000,000,  net of financing costs of US$37,863, for a net amount
of US$1,962,137.

The holders of the  preference  shares,  at the  discretion  of the directors of
Photon  Technology  International  (Canada),  Inc., but always in preference and
priority to any payment of  dividends on the common stock of the Company in each
year, are entitled to non-cumulative dividends at the rate of $0.50 per share.

In  conjunction  with  the  issuance  of the  preference  shares,  a put  option
agreement  was  adopted  between  the  Company  and the holder of the  preferred
shares.  Under this agreement,  the Company granted to the holder an irrevocable
and transferable right to require the Company to purchase from the holder, on or
after March 7, 1998, some or all of the preference  shares. The retraction price
for each  preference  share is the then current  market  price of the  Company's
common  shares.  The Company then has five  business days in which to notify the
holder of its  election  of whether it will  satisfy the put price in cash or by
the  issuance  of  common  stock of the  Company  (subject  to  equivalence  and
adjustment, if necessary).

NOTE I--PREFERENCE SHARES--Canadian Subsidiary--Continued

Any holder of a  preference  share is  entitled  on or after  March 7, 1998,  to
require Photon  Technology  International  (Canada),  Inc. to redeem all, but no
less than all, of such holder's preference shares for the redemption price equal
to the then  current  market  price of the  Company's  common  shares,  plus any
declared and unpaid  dividends.  The holder of the preference  shares has agreed
not to  exercise  its  redemption  right  unless  the  Company  defaults  on its
obligations under the put option agreement described above. The share provisions
also contain an adjustment  provision in relation to the redemption price on the
basis that each preference share is and is intended to be the equivalent of each
common share of the Company, to the effect that any change in the equivalence of
the  preference  shares with the common stock of the Company,  as  determined in
good  faith by the  board of  directors  of the  Company,  will  result  in such
adjustment  to  the  redemption  price  as  is  required  to  re-establish  such
equivalence.

NOTE J--STOCK OPTIONS

The  Company  adopted  a Stock  Option  Plan  (the  "Plan")  in 1987 to  provide
incentive and  non-qualified  common stock options for officers,  key employees,
and directors of the Company.  The number of authorized  shares  issuable in the
option  pool is 300,000  at June 30,  1997 (an  additional  66,667  shares  were
authorized  during fiscal 1997). The plan limits the maximum number of shares of
common  stock for which any one  participant  may be granted  stock  options per
calendar year to 100,000 shares.

The Plan was  established  primarily  to assist  the  Company in  retaining  the
services of valued  employees,  directors,  and consultants by offering them the
opportunity to acquire an equity  interest in the Company and to aid the Company
in  attracting  those  individuals  whose  services  would be  essential  to the
Company's future success.

The  Plan  is  divided  into  two  separate  equity  incentive  programs:  (a) a
discretionary   option  grant  program  under  which  executive  officers,   key
employees,  non-employee  directors,  and  consultants may be granted options to
purchase  shares of the  Company's  common stock at the  discretion  of the plan
administrator;  and (b) an automatic  option grant program under which  eligible
non-employee  directors will automatically  receive,  at periodic intervals over
their period of Board service,  special option grants to purchase  shares of the
Company's common stock.

NOTE J--STOCK OPTIONS--Continued

The options granted under the discretionary  option grant program vest after one
year from the grant date,  unless  otherwise  provided in the option  agreement.
Options  granted  under the  automatic  option grant  program will vest (and the
Company's repurchase rights of the option shares will lapse) in three successive
equal annual installments over the optionee's period of Board service,  with the
first such  installment to vest upon the completion of one year of Board service
measured from the automatic grant date.

All options  granted have a maximum term of ten years from grant date,  and each
option has an exercise price equal to 100% of the fair market value per share of
the Company's common stock on the grant date.

For the year ended June 30, 1997, the Company  granted 45,999 stock options,  of
which 36,000 options were issued to executive  officers,  and 9,999 options were
issued to directors.  For fiscal 1996, the Company granted 35,110 stock options,
of which 25,110  options were issued to executive  officers,  and 10,000 options
were issued to directors.  No options were exercised in fiscal 1997 and 1996. In
1997, 37,699 options were cancelled (1996 nil).

197,471  options or 66% of the  authorized  shares in the option  pool have been
granted as of June 30, 1997,  of which 151,472 are  exercisable.  Of the granted
options, 86,661 or 44% are under the automatic option grant program, and 110,810
or 56% are under the discretionary  option grant program.  The exercise price of
the common stock options range from $1.31 per share to $4.50 per share, and on a
weighted average basis approximates $3.57 per share. The granted and outstanding
options have expiration dates ranging from 1999 to 2007.

See Notes D and E for  descriptions  of the  options  granted by the  Company to
Silicon  Valley  Bank  and  C.I.  -  C.P.A.   Business   Ventures  Fund,   Inc.,
respectively.

executives in lieu of paying an earned 1994 cash bonus.  The stock was issued at
a fair market value of $30,000 or $3.75 per share.

outstanding   liabilities  of  the  previous   German   distributor,   including
outstanding payables to various vendors, unpaid compensation and social costs of
certain employees.

NOTE O--GERMAN SUBSIDIARY--Continued

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:

         Inventory                                      $ 216,000

The  operating  results  in fiscal  1995 of  German  Subsidiary,  subsequent  to
September 30, 1994,  were included in the Company's  result of  operations.  The
minority  interest's 49% share of German  Subsidiary's  income was deducted from
the determination of net income of the Company in 1995.

On July 5, 1995,  the Company  acquired the  remaining  49%  ownership of German
Subsidiary  from its minority  shareholders.  The Company  issued  50,000 common
shares from treasury  stock,  at a value of $3.00 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:

Goodwill on acquisition                                  $ 72,000
Net assets acquired from minority interest                 78,000

In fiscal 1996, the Company  assumed an additional  $43,000 of liabilities  with
respect  to the 51%  acquisition  of the German  Subsidiary,  which was added to
goodwill in other assets.

The operating  results of German  Subsidiary for fiscal 1996 were fully included

NOTE P--STOCK COMPENSATION

The Company has elected to follow  Accounting  Principles  Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25), and related Interpretations
in accounting for its employee stock options. Under APB 25, because the exercise
price of the Company's  employee  stock  options  equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

For a summary  description  of the  principal  features of the  Company's  stock
option plan, see Note J--Stock Options.

Pro forma  information  regarding  net income and earnings per share is required
under  the  Statement  of  Financial   Accounting   Standards  (FASB)  No.  123,
"Accounting  for Stock Based  Compensation,"  and has been  determined as if the
Company had accounted for its employee stock options under the fair value method
of that Statement. The fair value for these options was estimated at the date of
grant  using  a   Black-Scholes   option   pricing   model  with  the  following
weighted-average   assumptions  for  1997:  risk-free  interest  rate  of  6.35%
(1996-5.56%);  dividend yields of 0.0%  (1996-0.0%);  volatility  factors of the
expected market price of the Company's common stock of 2.423 (1996-1.164); and a
weighted-average expected life of the option of 5 years (1996-5 years).

The Company's pro forma information for the years ended June 30, is as follows:

NOTE Q--RECENT ACCOUNTING PRONOUNCEMENTS

New U.S. accounting  standards regarding the determination of earnings per share
have recently  been issued by the  Financial  Accounting  Standards  Board.  The
Company will initially  adopt these new standards,  commencing  with its interim
financial statements for the period ended December 31, 1997. Adoption of the new
standards, which involves restatement of net income (loss) per share amounts for
prior  periods,  is  expected to have no material  effect on the  Company's  net
income (loss) per share amounts.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--Continued (in US$)

NOTE S--FAIR VALUE OF FINANCIAL INSTRUMENTS--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 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 T--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. Actual amounts may differ
from estimates.

The Company's major products are electro-optical and light-based instrumentation
which utilizes fluorescence  technology.  The primary-markets 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 has  established a solid  customer base which  provides
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.    This   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.
