ITEM 1.  BUSINESS.

         1.       General.

                  EDITEK,  Inc.,  a  Delaware  corporation,   was  organized  in
September,   1986  to  succeed  the  operations  of  a  predecessor   California
corporation.  EDITEK,  Inc. and its  subsidiaries are referred to herein as "the
Company".  The Company  currently  operates two  toxicology  laboratories  which
provide testing services for  identification of substances of abuse. The Company
also develops,  manufactures and markets on-site  diagnostic and screening tests
which are used to detect substances in humans, foodstuffs, animals, feed and the
environment.

                  The Company  entered the  laboratory  business on February 11,
1994 when it completed the acquisition of Princeton  Diagnostic  Laboratories of
America,  Inc.  ("PDLA")  which  is now a  wholly  owned  subsidiary.  PDLA  was
incorporated  in Delaware in December,  1986.  On December 22, 1986, it acquired
from Stauffer Chemical Company, a subsidiary of Cheesebrough-Pond's Inc., all of
the Common  Stock of  Psychiatric  Diagnostic  Laboratories  of  America,  Inc.,
through  which PDLA conducts most of its  operations.  On January 30, 1996,  the
Company  acquired  the assets and  certain  liabilities  of another  laboratory,
MEDTOX Laboratories, Inc. ("MEDTOX").

                  The combination of laboratory services and the Company's other
products  and  services  allows the Company to offer a full line of products and
services for the  substance  abuse  testing  marketplace,  including (1) on-site
tests  for  the  detection  of  substance  of  abuse  drugs   (EZ-SCREEN(R)  and
VERDICT(R));  (2) on-site disposable qualitative determination of alcohol
intoxication; (3) Substance Abuse and Mental Health  Services Administration
(SAMHSA), formerly NIDA, certified laboratory testing (screening and
confirmation); (4) accessory items (gloves, specimen containers, permanent
recording temperature strips); and (5) consultation. Sales of these substance
abuse testing products and services accounted for approximately 73% of the
revenues  of the Company for the year ended December 31, 1995.

                   In 1993  diAGnostix,  inc. was incorporated by the Company in
Delaware  as  a   wholly-owned   subsidiary  to  address  the  broadly   defined
environmental  testing  marketplace.  On  June  1,  1995  the  Company,  through
diAGnostix,  inc.,  acquired  Bioman  Products,  Inc. In addition to selling the
Company's  diagnostic  products for the  environmental  and agri/food  industry,
diAGnostix, inc. is currently sourcing additional products manufactured by other
companies  that could be sold through  diAGnostix,  inc. It is also  anticipated
that  the  first  products  having  civilian  applications  resulting  from  the
Company's  research  and  product  development  efforts  with the United  States
Department  of  Defense  will be  oriented  towards  the  environmental  testing
marketplace and sold through diAGnostix, inc. Sales of the products sold through
diAGnostix,  inc.  accounted for approximately 14% of the Company's  revenues in
the year ended December 31, 1995.

<PAGE>

                  The Company also sells prepared and dehydrated  culture media,
animal blood products,  sera and plasma,  custom antisera,  and other biomedical
products  and  supplies,  which are either  produced by the Company or purchased
from other suppliers.  The Company also markets contract  manufacturing services
which utilize the same manufacturing equipment and processes used to manufacture
the on-site products.  The Company expects sales of these products and services,
which were first  introduced  in 1986,  to account for a smaller  portion of its
future revenues due to management's decision to focus primarily on the marketing
of its  laboratory  services and diagnostic  tests.  Sales of these products and
services  accounted for  approximately 5% of the revenues of the Company for the
year ended December 31, 1995.

                  The balance of the Company's  revenues are from work performed
for the U.S. Department of Defense including product sales as well as royalties,
fees and other income. This represented  approximately 8% of the revenues of the
Company for the year ended December 31, 1995.

                  Recent Developments.

                  On January  30,  1996,  the  Company  acquired  the assets and
certain  liabilities of MEDTOX.  MEDTOX was formed in 1984 and is located in St.
Paul, Minnesota. MEDTOX was founded in 1984 by Dr. Harry G. McCoy. Dr. McCoy saw
the need for a state-of-the-art,  full service,  toxicology reference laboratory
that  would  provide  timely,  accurate  analysis  for a wide range of drugs and
toxins.  From  its  inception,  MEDTOX  has  fulfilled  that  goal  by  offering
broad-based toxicology services, including 24 hour emergency service at no extra
cost to the client, therapeutic drug monitoring, medico-legal investigations and
other services.

                  MEDTOX rapidly gained a reputation for high quality and superb
customer service in the local Minnesota  medical market through the provision of
toxicology  laboratory  services  for local  hospitals,  physicians  and general
medical laboratories.  MEDTOX then began an expanded regional program as well as
national marketing which increased revenues and expanded the customer base.

                  In 1987, MEDTOX purchased its largest Minneapolis  competitor,
Metropolitan  Medical  Center  ("MMC"),  and gained  the  services  of Dr.  Gary
Hemphill,  one of the leading  scientists  and  laboratory  directors  at MEDTOX
today.  Dr.  Hemphill  and MMC also  gave  MEDTOX  a  foothold  in the  emerging
employment drug screening business.

                  With  the  creation  of  National  Institute  for  Drug  Abuse
("NIDA")  in 1988 to  oversee  mandated  drug  screening  for  safety  sensitive
employees, MEDTOX became one of the first ten laboratories in the country on the
original list of NIDA certified laboratories.  MEDTOX business then rapidly grew
in two major toxicology market segments:

   1. Forensic toxicology (substance abuse testing).
   2. Medical  toxicology - the  provision of reference  toxicology  testing the
     areas of therapeutic drug monitoring,  etc., for hospitals,  physicians and
     general  clinical   laboratories   lacking  the  sophisticated   toxicology
     capabilities of MEDTOX.

<PAGE>

                  For the year ended  December  31, 1995 MEDTOX had net revenues
of  $20,219,000  with  net  income  of  $2,879,000.   See  Unaudited  Pro  Forma
Consolidated  Financial  Information  contained  herein.  In connection with the
acquisition  of MEDTOX,  the Company  determined  that it would be beneficial to
consolidate the laboratory  operations of PDLA into the laboratory operations of
MEDTOX. Also, the Company decided to down size certain administrative  positions
at both  PDLA  and  MEDTOX  in  order  to  eliminate  duplicate  functions.  The
consolidation  plan,  which  was  put  in  place  prior  to the  closing  of the
acquisition of MEDTOX, will be complete by early in the second quarter of 1996.

         2.       Principal Services, Products, and Markets.

                  General. The Company's principal sources of revenues come from
the sale of drugs of abuse laboratory  testing services and products including a
variety of on-site screening products.

                   A.  Drug  Abuse  Laboratory  Testing  Services.  The  primary
business  focus of the Company is the provision of laboratory  testing  services
for the  identification  of drugs of  abuse.  These  tests are  conducted  using
methodologies  such  as  enzyme  immunoassay,   radio  immunoassay,  gas  liquid
chromatography,  high pressure liquid chromatography and gas chromatography/mass
spectrometry.   The  Company  has  pioneered   security  and  chain  of  custody
procedures,  including sample bar coding,  to help maintain the integrity of the
specimens and the confidentiality of the test results.

                  The Company's  customers for abused substance  testing include
public  and  private  corporations.  Among  this  customer  base  are  Fortune
500 companies. In addition to public and private corporations,  abused substance
testing  is also  conducted  on  behalf  of  service  firms  such  as  financial
institutions, drug treatment counseling centers and hospitals.

                  B. Products.  The Company's test products,  which were adapted
from assay  technologies  previously  developed in the 1970's for human  medical
diagnostics, are easy to use, inexpensive,  on-site tests. The tests are capable
of rapidly  detecting  the presence of a number of  substances in human urine or
blood  samples,  foodstuffs,  animals,  feed  and the  environment  without  the
necessity of instruments or technical personnel.  The Company's diagnostic tests
and the  disposable  devices used in connection  therewith are marketed under
the names EZ-SCREEN(R),  QUIK-CARD(R),  VERDICT(R), RECON(R) and EZ-QUANT(R),
which are registered trademarks of the Company. A QUIK-CARD together with the
necessary reagents, comprise an EZ-SCREEN test. EZ-SCREEN tests were first
introduced by the predecessor corporation of the Company in 1985. EZ-SCREEN
and VERDICT tests are utilized in agricultural diagnostics (which includes
mycotoxin  detection, drug  residue  surveillance,  feed  analysis,  and
regulatory  compliance)  and clinical diagnostics (which includes drugs of
abuse testing).  VERDICT and RECON are "self-performing",  one-step tests
marketed,  respectively,  to the drugs of abuse and Department of Defense
testing markets. The VERDICT and RECON tests were both introduced in 1993.
EZ-QUANT tests, first introduced in 1994 are microtiter, ELISA-based,
quantitative assays utilized in agricultural diagnostics.
 .

<PAGE>


                  Clinical  Diagnostics.  The  EZ-SCREEN  tests are also used in
clinical diagnostics to detect the presence of certain drugs of abuse in humans.
The Company now has  received  clearance  from the Food and Drug  Administration
("FDA") for  EZ-SCREEN  tests for six of the most  commonly  abused  substances:
cannabinoids, cocaine, opiates, barbiturates, amphetamines, and PCP. The Company
markets  this  product  line,  both  domestically  and  internationally,  to law
enforcement  agencies,   industrial  companies  for  pre-employment   screening,
physicians' offices, hospitals,  clinics and drug abuse counseling and treatment
centers.

                  VERDICT tests are used to detect the presence of certain drugs
of abuse in humans.  The Company is now marketing the VERDICT  cocaine test, the
VERDICT  THC test,  and the VERDICT  opiates  test.  The  Company  has  received
clearance  from the FDA for its VERDICT  cocaine test and VERDICT  opiates test.
The VERDICT THC test is being  marketed for forensic  use only,  pending  510(K)
premarket clearance from the FDA.

                  Alcohol Abuse Detection. The Company distributes on-site tests
for the detection of alcohol with the EZ-SCREEN  Breath  Alcohol Test.  The test
consists of a small tube  containing  chemically  treated  crystals  that change
color in the presence of alcohol. The Company purchases these products through a
distribution agreement with WNCK, Inc.

                  Agridiagnostic Tests. The EZ-SCREEN and EZ-QUANT tests are
used in agricultural diagnostics to detect, among other things, mycotoxins,
which are hazardous substances produced by fungal growth. Mycotoxins frequently
contaminate corn, wheat, rye, barley,  peanuts, tree nuts, cottonseed,  milk,
rice, and livestock feeds. The EZ-SCREEN  agridiagnostic tests are marketed to
regulatory  authorities  and  producers of foodstuffs  and feeds.

                  Conventional  Biodiagnostic Products. The Company manufactures
and/or  distributes a variety of products used by researchers,  clinical testing
laboratories,  government  agencies  and private  industry  for  veterinary  and
agricultural  testing  purposes.  These products include prepared and dehydrated
culture  media,  animal  blood  products,   sera  and  plasma,  custom  antisera
(consisting of polyclonal antibodies to a variety of antigens), immunodiagnostic
kits, species  identification plates and other biomedical products and supplies.
The Company produces laboratory diagnostic kits for detection of sulfa drugs and
other  antibiotics in livestock,  and distributes a variety of other  biomedical
products and supplies produced by other manufacturers.

                  3.       Marketing and Sales.

                  The  Company  believes  that the  combined  operations  of the
laboratory operations and the on-site test kits manufactured by the Company have
created  synergy in the  marketing  of  comprehensive,  on-site  and  laboratory
testing  programs  to a common  customer  base.  The Company is in a position to
offer a full line of products  and  services  for the  substance  abuse  testing
marketplace, including (1) on-site tests for the detection of substance of abuse
drugs  (EZ-SCREEN  and  VERDICT);   (2)  on-site  qualitative  and  quantitative
determination of alcohol intoxication (both disposable and electronic instrument
detection devices);  (3) SAMHSA certified laboratory testing (PDLA screening and
confirmation);  (4) accessory  items  (gloves,  specimen  containers,  permanent
recording  temperature  strips);  and (5) consultation.

<PAGE>


                  diAGnostix,  Inc. The Company currently markets its
EZ-SCREEN, EZ-QUANT, and other tests through diAGnostix, Inc. with an
internal sales and marketing department as well as through various distribution
agreements with third party distributors.  The Company has current distribution
arrangements throughout Europe, Japan and other countries worldwide.  Customers
for products sold through diAGnostix include livestock producers, food
processors,  veterinarians,  and government agencies.

                  Other.  The Company also provides  Conventional  Biodiagnostic
Products.   Customers  for  Conventional   Biodiagnostic   Products  consist  of
government agencies,  testing laboratories,  manufacturers of medical diagnostic
products, and researchers.

                  Major Customers. Sales to the United States government and its
agencies,  primarily  the United  States  Department  of  Agriculture  ("USDA"),
amounted to  approximately  4% of the Company's  total revenues during 1995. The
majority of these sales are through two separate  multi-year  contracts with the
United States  Department of  Agriculture.  One contract  expires  September 30,
1996, and the other expires September 30, 1999. Both these contracts are subject
to annual renewals by the USDA.

                  Sales to foreign customers,  primarily distributors,  amounted
to  approximately 8% of the Company's total revenues during 1995. No one foreign
customer represented more than 5% of the Company's total revenues.

         4.       New Products.

                  During 1995 the primary  research and  development  efforts of
the Company focused on the development of tests to extend the product  offerings
in each of the immunoassay product lines produced by the Company.  These product
lines  consist  of  the  VERDICT/RECON  "self-performing"  immunochromatographic
assays,  the  EZ-SCREEN  membrane-based  enzyme  immunoassays,  and the EZ-QUANT
microtiter immunoassays.

                  VERDICT  Tests for Drugs of Abuse - During 1995  research  and
development  efforts were  directed to continued  support and  refinement of the
currently  marketed  VERDICT  one-step  tests for the detection of cocaine,  THC
(marijuana), and opiate metabolites and to the development of additional VERDICT
tests for the detection of phencyclidine  (PCP),  amphetamines and barbiturates.
Clinical evaluation of the VERDICT PCP test was completed in December,  1995 and
the product was released for sale for forensic use in February,  1996.  Clinical
evaluation of the VERDICT  Amphetamines and VERDICT  Barbiturates  tests will be
conducted  in early  1996 with a planned  product  release  for sale  during the
second  quarter,  1996.  Additional  efforts  in 1996  will be  directed  toward
development of VERDICT tests for benzodiazepines and methadone and to the design
of a test device  which would permit

<PAGE>


simultaneous testing of a sample for five different drugs of abuse following the
addition of a single sample.

                  RECON  Tests  for  Agents of  Biological  Origin - In 1991 the
Company successfully  completed a "proof of principle" study under contract with
the U.S.  Department  of Defense (DOD) to develop  rapid,  on-site tests for the
detection of certain biological materials.  Since September 1991 the Company has
had an ongoing contract to continue this development  program. The initial phase
of the ongoing  contract led to  development  of  EZ-SCREEN  tests for 6 agents,
Botulinum  Toxins A and B, B.  anthracis,  Staphylococcal  Enterotoxin  B, Ricin
Toxin,  Spore  Simulant and Botulinum  Toxin E. Currently the contract calls for
the  development of RECON  one-step  tests for nine agents of biological  origin
using reagents supplied by the U.S. Government.  The contract also calls for the
supply of a limited  number of each of these RECON tests to agencies  within the
DOD for evaluation  purposes.  In December 1995  production of the last of three
trial  production lots of tests for four of the agents began.  Shipment of these
four tests for Ricin Toxin,  Plague F1,  Staphylococcal  Enterotoxin B and Spore
Simulant  were  completed  during the first  quarter 1996 as was delivery of the
first lot of tests for one additional agent.  Additional efforts in 1996 will be
directed toward completing  development of tests for three additional agents and
toward  production of trial lots of the five remaining agents. As of December
31, 1995 the total value of the  contract  was  $1,177,000  and a total of
$941,000  had been billed under the contract to date.

                  EZ-SCREEN  Tests for Drugs of Abuse - During  1995 the primary
EZ-SCREEN  research and  development  effort was directed toward the development
and clinical  evaluation  of the  EZ-SCREEN  PROFILE  drugs of abuse test.  This
product,   released  for  sale  for  forensic  use  in  February,  1996  permits
simultaneous  testing  of a  single  urine  sample  for THC,  cocaine,  opiates,
amphetamines  and PCP. During 1996, the EZ-SCREEN  PROFILE product will be fully
transitioned to  manufacturing,  development  work on EZ-SCREEN  Benzodiazepines
will be  completed  and  development  of an  EZ-SCREEN  Methadone  test  will be
initiated.

                  EZ-QUANT Tests for  Mycotoxins  and  Antibiotic  Residues - In
1995, the Company's  research and development group completed the development of
an EZ-QUANT test for determining the  concentration of  deoxynavalenol  (DON) in
various food products.  The EZ-QUANT DON test, which utilizes  reagents provided
to the Company under a sole distribution  agreement with Agriculture Canada, was
released  for sale in  September  1995.  Also in 1995 work was  initiated on two
additional EZ-QUANT products. The EZ-QUANT  Chloramphenicol test was released in
February 1996 and the EZ-QUANT  Ochratoxin  test will be released in 1996.
Additional effort in 1996 will be directed towards  transitioning  production of
the EZ-QUANT products to manufacturing and pursuing Association of Official
Analytical   Chemists  (AOAC)   Research   Institute certification of the
EZ-QUANT Aflatoxin product.

                  Biosensors  - In  March,  1995  the  Company  entered  into  a
Research Collaboration Agreement with Battelle Memorial Institute to explore the
commercial  feasibility of utilizing the Company's  immunoassay  reagents with a
novel,   state-of-the-art  biosensor  instrument  developed

<PAGE>

by Battelle under contract with the  Department of Defense.  It was  anticipated
that if the studies proved  successful,  the Company would continue working with
Battelle  toward the  creation of products  for  commercial  application  of the
biosensor  system,  initially  for food  safety  testing  purposes.  At year end
studies had been completed which demonstrated detection of low levels of labeled
aflatoxin B1 conjugate with good signal to noise ratio. Studies are now underway
to determine the  performance  and  sensitivity of the biosensor  system for the
detection of aflatoxin in a corn matrix. Upon completion of these studies,  data
will be analyzed and a decision made relative to potential follow-on activity.

                  Other Tests - The Company is assessing on a preliminary basis,
the market  opportunity  for and  feasibility  of  developing  other  EZ-SCREEN,
EZ-QUANT and one-step tests for the detection of other mycotoxins,  antibiotics,
drugs of abuse and other  conditions  found in humans or animals.  Opportunities
for  development  of assays  using other  technologies  are also  assessed on an
ongoing basis.

         5.       Research and Development.

                  The  markets  for  agridiagnostic   and  clinical   diagnostic
products are highly competitive, and innovations and technological changes occur
frequently.  For these  reasons,  the Company has devoted  substantial  funds to
research and  development of its immunoassay  products.  During the fiscal years
ended  December  31,  1995,  1994 and 1993,  the  Company  incurred  expenses of
$920,000, $729,000, and $825,000 respectively,  for research and development. In
1995,  $201,000,  of the expenses  incurred for  research and  development  were
reimbursed by outside parties or involved  charges for which outside parties had
reimbursement  commitments.  As of December  31, 1995,  the Company  employed 14
people in research and development, 6 of whom hold Ph.D.'s.

         6.       Raw Materials.

                  The raw materials  required by the  laboratory  for urine drug
testing  consist  primarily  of two  types:  specimen  collection  supplies  and
reagents for laboratory  analysis.  The collection supplies include Drug Testing
Custody and Control Forms that identify the specimen and the client,  as well as
document  the  chain-of-custody.  Collection  supplies  also consist of specimen
bottles and shipping boxes.  Reagents for drug testing are primarily immunoassay
screening  products and various  chemicals used for  confirmation  testing.  The
Company believes all of these materials are available at competitive prices from
other suppliers.

                  The primary raw materials  required for the  immunoassay-based
test kits  produced by the Company  consist of  antibodies,  antigens  and other
reagents,  plastic injection-molded devices, glass fiber,  nitrocellulose filter
materials,  and packaging  materials.  The Company maintains an inventory of raw
materials  which,  to date,  has been  acquired  primarily  from third  parties.
Currently,  most raw materials are available from several  sources.  The Company
possesses  the  technical  capability  to  produce  its own  antibodies  and has
initiated  production of antibodies for certain tests.  However,  if the Company
were to change its source of supply for

<PAGE>



raw  materials  used  in  a  specific  test,  additional  development,  and  the
accompanying  costs,  may be  required  to adapt the  alternate  material to the
specific diagnostic test.

         7.    Patents, Trademarks, Licensing and Other Proprietary Information.

                  The Company holds nine issued United States patents,  eight of
which  generally  form the basis for the  EZ-SCREEN  and one-step  technologies.
Additionally,  the Company has one patent which  relates to methods of utilizing
whole blood as a sample  medium on its  immunoassay  devices.  The Company  also
holds various patents in several foreign  countries.  The Company also holds two
United  States  patents  which  it  acquired  in  the   acquisition  of  Granite
Technological Enterprises, Inc. in 1986.

                  Of the eight U.S. patents mentioned above which generally form
the basis for the EZ-SCREEN and one-step technologies,  one expires in 2000, one
expires in 2004,  five expire in 2007, and one expires in 2010. The patent which
relates to the methods of utilizing  whole blood as a sample  medium  expires in
2012.

                  There can be no  guarantee  that there will not be a challenge
to the  validity of the patents.  In the event of such a challenge,  the Company
might be required to spend  significant  funds to defend its patents,  and there
can be no assurance that the Company would be successful in any such action.

                  The  Company  holds  twelve   registered  trade  names  and/or
trademarks  in reference to its products and  corporate  names.  The trade names
and/or  trademarks  of the Company  range in duration  from 10 years to 20 years
with  expiration  dates ranging from 2001 to 2008.  Applications  have also been
made for additional trade names.

                  The Company believes that the basic technologies  requisite to
the  production of antibodies  are in the public domain and are not  patentable.
The Company intends to rely upon trade secret protection of certain  proprietary
information,  rather than patents,  where it believes disclosure could cause the
Company to be vulnerable to  competitors  who could  successfully  replicate the
Company's production and manufacturing techniques and processes.

         8.       Seasonality.

                  The Company  believes that the laboratory  testing business is
subject to  seasonal  fluctuations  in  pre-employment  screening  which has low
points in August and  December  annually.  The  Company  does not  believe  that
seasonality is a significant  factor in sales of its on-site  immunoassay tests.
However,  the  Company  believes  that  sales of  certain  of its  tests for the
agricultural  markets such as its  EZ-SCREEN:AFLATOXIN  test  coincide  with the
harvesting of crops meant for human and animal consumption.

         9.       Backlog.

<PAGE>

                  At December 31, 1995, the Company did not have any significant
backlog and normally does not have any significant backlog. The Company does not
believe that recorded sales backlog is a significant factor in its business.

         10.      Competition.

                  Laboratory Services. Competition in the area of drugs of abuse
testing is intense.  Competitors  and  potential  competitors  include  forensic
testing units of large clinical laboratories, such as Laboratory Corporation
of America Holdings, Corning/Metpath Laboratories and SmithKline Laboratories,
Inc. and other independent laboratories, other specialized laboratories, and
in-house testing facilities maintained by hospitals.

                  Competitive factors include reliability and accuracy of tests,
price structure, service,  transportation collection networks and the ability to
establish  relationships  with  hospitals,  physicians,  and users of drug abuse
testing programs. It should be recognized, however, that many of the competitors
and  potential  competitors  have  substantially  greater  financial  and  other
resources than the Company.

                  The industry in which the Company competes is characterized by
service issues including turn-around time of reporting results, price, the
quality and reliability of results, and an absence of patent or other
proprietary protection. In addition,  since tests performed by the Company are
not protected by patents or other proprietary rights, any of these tests could
be performed by competitors. However, there are proprietary assay protocols for
the more specialized testing that are unique to the company.

                  Some specific segments of the laboratory testing business are
price competitive with low  margins. Other  segments,  which  place a premium on
quality,  constitute  a large part of the  business of MEDTOX,  where,  to date,
quality service has been a more important  competitive  factor than price.  This
has allowed MEDTOX to generate positive gross margins and operating income.  The
Company's ability to successfully  compete in the future and maintain it margins
will be based on its  ability to  maintain  its  quality  and  customer  service
strength while maintaining efficiencies and low cost operations. There can be no
assurance  that price  competitiveness  will not  increase  in  importance  as a
competitive factor in the business of MEDTOX.

                  Immunoassay  Tests.  The diagnostics  market has become highly
competitive with respect to the price,  quality and ease of use of various tests
and is characterized by rapid technological and regulatory changes.  The Company
has designed its on-site tests as inexpensive, on-site tests for use by
unskilled personnel,  and has not  endeavored to compete with laboratory-based
systems.  Numerous large  companies with greater  research and development,
marketing,   financial,  and  other capabilitied, as well as government-funded
institutions  and  smaller  research  firms,  are  engaged in research,
development and marketing of diagnostic assays for application in the areas
for which the Company produces its products.

<PAGE>

                  The Company has experienced increased competition with respect
to its immunoassay tests from systems and products developed by others,  many of
whom compete solely on price. As the number of firms marketing diagnostic tests
has grown, the Company has experienced increased price competition.  A further
increase in competition  may have a material adverse effect on the business and
future financial prospects of the Company.

         11.      Government Regulations.

                  The  products  and  services of the Company are subject to the
regulations of a number of governmental agencies as listed below. It is believed
that the Company is currently in compliance with all regulatory authorities. The
Company cannot predict whether future changes in governmental  regulations might
significantly  increase  compliance  costs or adversely  affect the time or cost
required to develop and  introduce new  products.  In addition,  products of the
Company are or may become subject to foreign regulations.

                           1. United States Food and Drug Administration  (FDA).
Certain  tests for human diagnostic purposes  must be cleared by the FDA prior
to their marketing for in vitro  diagnostic use in the United States.  The
FDA regulated products produced by the Company are in vitro diagnostic  products
subject  to  FDA  clearance  through  the  510(k)  process  which  requires  the
submission of information and data to the FDA that  demonstrates that the device
to be marketed is substantially  equivalent to a currently marketed device. This
data is generated by performing  clinical studies comparing the results obtained
using the  Company's  device to those  obtained  using an existing test product.
Although no maximum statutory  response time has been set for review of a 510(k)
submission,  as a matter of policy the FDA has  attempted to complete  review of
510(k)  submissions  within 90 days.  To date,  the Company has received  510(k)
clearance  for 10 different  products and the average time for  clearance was 58
days with a maximum  of 141 days and a minimum of 20 days.  Products  subject to
510(k) regulations may not be marketed for in vitro diagnostic use until the FDA
issues a letter stating that a finding of substantial equivalence has been made.

                           As  a  registered   manufacturer   of  FDA  regulated
products,  the Company is subject to a variety of FDA regulations  including the
Good Manufacturing Practices (GMP) regulations which define the conditions under
which FDA regulated products are to be produced.  These regulations are enforced
by FDA and failure to comply with GMP or other FDA regulations can result in the
delay of premarket product reviews,  fines, civil penalties,  recall,  seizures,
injunctions and criminal prosecution.

                           2. Health Care Financing  Administration  (HCFA). The
Clinical Laboratory  Improvement Act (CLIA) introduced in 1992 requires that all
in vitro diagnostic products be categorized as to level of complexity. A request
for CLIA  categorization of any new clinical laboratory test system must be made
simultaneously  with FDA 510(k) submission.  The EZ-SCREEN and VERDICT drugs of
abuse tests currently marketed by EDITEK have been categorized as moderately
complex. The complexity  category to which a clinical laboratory test system
is assigned may limit the number of laboratories qualified to use the test
system thus impacting product sales.

<PAGE>

                           3. United States  Department of  Agriculture  (USDA).
The  Company's  animal  facilities  are  subject to and comply  with  applicable
regulations  of the USDA.  The  livestock  related  products  of the Company may
become  subject to state  regulation  but the Company  does not  anticipate  any
difficulties in complying with these regulations, if enacted.

                           4. United States  Department of Defense  (DOD).  With
reclassification  of the Company's  contract with the DOD from  UNCLASSIFIED  to
SECRET, it has been necessary to establish the appropriate  security  procedures
and  facilities,  including  designation of a Facility  Security  Officer who is
responsible for overseeing the security  system,  including  conduct of periodic
security audits by appropriate  defense agencies.  Additionally,  the Company is
now  subject to  periodic  audits of its  accounting  systems and records by the
Defense Audit Agency.

                           5. Drug Enforcement Administration (DEA). The primary
business of the Company involves either testing for drugs of abuse or developing
test kits for the detection of drugs/drug  metabolites in urine. PDLA and MEDTOX
laboratories  are  registered  with the DEA to conduct  chemical  analyses  with
controlled  substances.  The  EDITEK  facility  is  registered  by  the  DEA  to
manufacture and distribute  controlled  substances and to conduct  research with
controlled  substances.  Maintenance  of these  registrations  requires that the
Company comply with applicable DEA regulations.

                           6.  Substance   Abuse  and  Mental  Health   Services
Administration  (SAMHSA).  Both PDLA and MEDTOX  laboratories  are  certified by
SAMHSA,  PDLA since 1989 and MEDTOX since 1988.  SAMHSA  certifies  laboratories
meeting  strict  standards  under Subpart C of Mandatory  Guidelines for Federal
Workplace Drug Testing Programs. Continued certification is accomplished through
periodic inspection by SAMHSA to assure compliance with applicable regulations.

                           7. Additional  Laboratory  Regulations.  The PDLA and
MEDTOX  laboratories  and certain of the  laboratory  personnel  are licensed or
otherwise regulated by certain federal agencies, states, and localities in which
PDLA and MEDTOX conduct business.  Federal, state and local laws and regulations
require PDLA and MEDTOX,  among other things,  to meet  standards  governing the
qualifications of laboratory owners and personnel, as well as the maintenance of
proper  records,  facilities,  equipment,  test  materials,  and quality control
programs.  In  addition,  both  laboratories  are  subject  to a number of other
federal,   state,  and  local  requirements  which  provide  for  inspection  of
laboratory  facilities  and  participation  in proficiency  testing,  as well as
govern the transportation, packaging, and labeling of specimens tested by either
laboratory.   The   laboratories  are  also  subject  to  laws  and  regulations
prohibiting  the  unlawful  rebate  of fees and  limiting  the  manner  in which
business may be solicited.
                           Both laboratories receive and use small quantities of
hazardous  chemicals  and  radioactive  materials  in their  operations  and are
licensed to handle and dispose of such  chemicals  and  materials.  Any business
handling or disposing of hazardous and radioactive waste is subject to potential
liabilities under certain of these laws.

<PAGE>



         12.      Product Liability.

                  Manufacturing  and marketing of products by the Company entail
a risk of product liability claims.  The exposure to product liability claims in
the past was  mitigated to some extent by the fact that the  Company's  products
were  principally  directed  toward food  processors (as  contrasted  with human
diagnostics)  and most of its Conventional  Biodiagnostic  Products were used as
components in research,  testing or manufacturing by the purchaser and conformed
to the purchaser's  specifications.  However, a greater portion of the Company's
current  revenues  result  from  sales  of  human  diagnostic   tests,   thereby
potentially increasing exposure to product liability claims. On August 13, 1993,
the Company procured  insurance  coverage against the risk of product  liability
arising out of events after such date,  but such insurance does not cover claims
made  after  that  date  based on  events  that  occurred  prior  to that  date.
Consequently, for uncovered claims, the Company could be required to pay any and
all costs  associated with any product  liability claims brought against it, the
cost of defense whatever the outcome of the action,  and possible  settlement or
damages if a court rendered a judgment in favor of any plaintiff  asserting such
a claim against the Company.  Damages may include  punitive  damages,  which may
substantially  exceed actual  damages.  The obligation to pay such damages could
have a material adverse effect on the Company and exceed its ability to pay such
damages. No product liability claims are pending.

                  The  Company's   laboratory  testing  services  are  primarily
diagnostic and expose the Company to the risk of liability claims. The Company's
laboratories  have  maintained  continuous  Professional  and General  Liability
insurance since 1985. To date, the Company has not had any  substantial  product
liability and no material professional service claims are currently pending.

         13.      Employees.

                  As of  December  31,  1995,  the  Company  had  106  full-time
employees  compared to 100  full-time  employees as of December 31, 1995. Of the
106 full-time employees,  39 were in laboratory  operations and systems, 18 were
involved  in  research,  testing,  and  product  development  activities,  20 in
production and distribution, 14 in sales and marketing, and 15 in administrative
and clerical functions. Additionally, 8 of its personnel hold Ph.D. degrees.

                  As of January 30, 1996, MEDTOX had 247 employees, of which 199
were involved in laboratory operations, 18 were involved in sales and marketing,
5  were  involved  in  research  and   development   and  25  were  involved  in
administrative  and clerical  functions.  Additionally,  6 of its personnel hold
Ph.D. degrees.

                  The  consolidation  of the laboratory  operations from PDLA in
New  Jersey  into  the  laboratory  operations  of  MEDTOX  will  result  in the
elimination of 35 positions in New Jersey and the addition of certain of the
some positions in Minnesota.

<PAGE>

                  The  Company's  employees  are not  covered by any  collective
bargaining  agreements,  and the Company has not  experienced any work stoppages
and the Company considers its relations with its employees to be good.

                  14.      MEDTOX Acquisition and Capital Structure

                  The Company has undergone a significant  change as a result of
the  acquisition of MEDTOX and the associated  financing.  The following  points
represent  certain  potential risk factors  associated  with the acquisition and
financing.

                  1. Dependence on Sales of Equity. As of December 31, 1995, the
Company had not achieved a positive cash flow from operations.  Accordingly, the
Company relies on available credit arrangements, outside funding of research and
development  and continued  sales of its equity  securities  to fund  operations
until a  positive  cash flow can be  achieved.  From  January  1,  1991  through
December  31, 1995,  the Company  raised  approximately  $12 million from equity
financing  and issued  6,058,699  shares of the  Company's  Common  Stock for an
average price of $1.98 per share,  all of which were issued at a discount to the
market value of the Company's  Common Stock. In order to finance the acquisition
of MEDTOX, pay applicable costs and expenses and to provide working capital, the
Company raised  approximately  $20 million from the sale of the Preferred  Stock
and Common Stock. This amount and the amount borrowed,  as described below, have
allowed  the  Company to  consummate  the  MEDTOX  acquisition  and the  Company
believes  should  provide  enough  working  capital to help the Company  achieve
positive  cash flow.  If the Company is unable to achieve a positive  cash flow,
additional financing will be required. There can be no assurance that additional
financing  can be obtained or if  obtained,  that the terms will be favorable to
the Company.

                  2. Debt Service; Debt Seniority;  No Dividends. To finance the
acquisition  of MEDTOX and to provide  working  capital the Company  borrowed $5
million in January, 1996. The debt financing consists of two term loans totaling
$4 million and up to $7 million in the form of a revolving  line of credit based
on the receivables of the Company (the "Loan  Agreement").  The amount of credit
available to the Company  varies with the accounts  receivable and the inventory
of the Company.  On January 30, 1996, the receivables and inventory amounts made
$2.9  million  of the  credit  facility  available,  of which the total is still
available  at March 26, 1996.  There can be no  assurance  that the Company will
have sufficient  revenues to service  payments of principal and interest on this
indebtedness. Failure to service this indebtedness would have a material adverse
effect on the  Company.  The  indebtedness  of the Company will be senior to the
Series A  Preferred  Stock and shares of Common  Stock upon  liquidation  of the
Company.   Interest   payments  on  the  indebtedness  may  cause  there  to  be
insufficient  cash to pay any  dividends.  In addition,  the loan amount and the
line of credit agreement  contain  covenants that restrict the Company's ability
to pay  dividends  even if the  Company  has cash  available  from  which to pay
dividends.

                  3. Unexpected Effects of Merger(s).  The Company completed the
acquisition of the MEDTOX assets on January 30, 1996 (the "Closing  Date").  The
Company also acquired the assets and operations of Bioman Products, Inc. on June
1, 1995. In February  1994,  the  Company  acquired  Princeton  Diagnostic
Laboratories  of America, Inc. ("PDLA"). The Company  anticipates that

<PAGE>


certain  synergism will arise between the Company and Bioman, PDLA and MEDTOX.
However, there can be no assurance that any synergism will arise from the
recent acquisitions. The efforts required to integrate the business of the
Company with other operations may have a material adverse effect on the
operations of either the Company or the acquired company(s).

                  4.  Adverse  Effect  on Market  Price of Sales of the  Company
Stock. A substantial  number of shares of capital stock of the Company have been
issued in transactions  that are exempt from  registration  under the Securities
Act of 1933, as amended,  either in private placements or pursuant to
Regulation S.

                  On January 30, 1996 and February 2, 1996, the Company sold 303
shares  of  Series  A  Preferred  Stock  utilizing  the  exemption  afforded  by
Regulation  S of the  Commission  (the  "Offshore  Offering"),  which shares are
convertible  into a minimum  of  5,459,459  shares  of  Common  Stock and may be
convertible  into more shares of Common  Stock if the market price of the Common
Stock of the Company is less than $3.70 per share on the conversion dates. As of
March 26,  1996,  the market  price of the  Common Stock was $1.875 per share at
which price the 303 shares of Series A Preferred Stock would be convertible into
10,744,681  shares  of  Common  Stock,  based on a conversion price of $1.41 per
share or a 25% discount to the market price on March 26, 1996.

                  Regulation  S  provides  generally  that  offers or sales that
occur outside the United States and in compliance with the requirements  thereof
are not subject to the registration  requirements of the Act. Subject to certain
restrictions  and conditions  set forth  therein,  Regulation S is available for
offers and sales to investors that are not U.S. persons. Such offshore investors
who  purchase the shares of Series A Preferred  Stock in the  Offshore  Offering
pursuant to Regulation S are not permitted to transfer such shares or Conversion
Shares to a U.S.  Person  (defined  generally  as a resident  of the U.S.  or an
entity  organized  under  the laws of the U.S.) for a period of at least 40 days
after  February 2, 1996, the closing of the Offshore  Offering (the  "Restricted
Period"). Resales to buyers who are not U.S. persons are permitted at any time.

                  After the expiration of the Restricted  Period,  investors who
purchased  shares of Series A Preferred Stock in the Offshore  Offering may sell
such  shares  or  Conversion  Shares in the U.S.,  but only if such  shares  are
registered  or  an  exemption  from  registration  is  available.   Accordingly,
beginning on March 30, 1996 (the first day any investor  will be able to convert
shares of Series A Preferred  Stock into shares of Common Stock),  to the extent
that any offshore  investors have  converted  their shares of Series A Preferred
Stock into Common Stock, such offshore  investors will also be able to sell such
Common  Stock in the U.S.  if the  shares  are  registered  or an  exemption  is
available.


                  Sales of Conversion Shares for such offshore investors must be
made in compliance with an exemption from  registration.  The  agreements
between the Company and offshore investors provide that the stock certificates
for the


<PAGE>


Conversion Shares will not contain restrictive securities legends. Consequently,
if the Company complies with these agreements, the Company would not be able  to
prevent illegal resales of Series A Preferred Stock or Conversion Shares by
offshore investors and each offshore investor will make its own determination
whether such sales qualify for exemptions from registration. On  March 27, 1996,
the Company determined it would place legends on the certificates of shares of
Common  Stock to  assure that all  resales of securities are made in  compliance
with applicable securities laws. On March 27, 1996, the Company determined it
would place legends on Common Stock Certificates to assure that all resales of
securities are made in compliance with applicable securities laws. Since that
date, the Company has been in discussions with Preferred shareholders about
whether the Common Stock should be legended. In part to avoid protracted
litigation from Preferred shareholders and in part in reliance on the
cooperation of Preferred shareholders who have reaffirmed their intention to
comply with securities laws on all resales, the Company has begun to issue
Common Stock certificates without legends. The Company will seek to work
with its Preferred shareholders to assure compliance with securities laws on
resales. The Company intends to monitor trading in its stock closely,
but notwithstanding that the Preferred shareholders sell only pursuant to an
available exemption, there can be no assurance that the trading activities of
their transferees will not result in decreases in the market price of the
Company's Common Stock. The Company is continuing to discuss issues related
to conversion with its Preferred shareholders and may offer registration
rights and/or other rights to Preferred shareholders as an inducement to
delay conversion. There can be no assurance the issues related to resale of
the Common Stock of the Company issued pursuant to Regulation S will not have
a material adverse effect on the Company, including the ability of the
Company to raise additional capital in the future.



                  In  connection  with the  acquisition  of MEDTOX,  the Company
issued  2,517,306  to the former  shareholders  of MEDTOX and sold 104 shares of
Series A Preferred stock, all pursuant to Regulation D. The shares issued to the
former  shareholders of MEDTOX and the Common Stock issuable upon the conversion
of the 104 shares of Series A Preferred  Stock were  included on a  Registration
Statement  on Form S-3 which was filed on  February  9, 1996.  The 104 shares of
Series A Preferred  Stock would be convertible  into 3,652,482  shares of Common
Stock based on a  conversion  price of $1.41 per share or a 25%  discount to the
market price on March 26, 1996.


                  If  substantial  sales of the  Company's  Common  Stock occur,
whether by the investors in the Offshore Offering or by U.S.  investors pursuant
to the  Registration  Statement or  otherwise,  such sales could have a material
adverse effect on the market price of the Company's Common Stock.

                  5. Adverse Effect of Price Protection  Provisions.  The number
of  shares of  Common  Stock  issuable  upon  conversion  of a share of Series A
Preferred Stock will equal the number derived by dividing (i) the purchase price
of the Series A  Preferred  Stock  ($50,000  per share) by (ii) the lower of (x)
$2.775 or (y) 75% of the Market  Price of the Common Stock on the day the shares
of Series A Preferred  Stock are converted into Common Stock.  "Market Price" is
defined for this purpose as the daily  average of the closing bid prices  quoted
on the American  Stock  Exchange or other  exchange on which the Common Stock is
traded for the five trading days  immediately  preceding the date the shares are
converted.  Accordingly,  a minimum  of  7,333,333  shares  of Common  Stock are
issuable upon  conversion of the 407 shares of Series A Preferred  Stock sold in
both the U.S.  Offering  and the  Offshore  Offering,  but the actual  number of
shares of Common Stock issuable upon  conversion of the Series A Preferred Stock
will not be known until the time of issuance of the shares of Common  Stock upon
conversion.  As  of  March 26, 1996, the market price of  the  Common  Stock was
$1.875 per share at which price the 407 shares of Series A Preferred Stock would
be  convertible  into  14,432,624  shares of Common Stock, based on a conversion
price of $1.41 per share or a 25% discount to the market price on
March 26, 1996.

                  The MEDTOX Asset  Purchase  Agreement  provides that, if after
the Closing Date the market  value of the Common  Stock of the Company  declines
below $1.986 per share during four specified  periods (the "Repricing  Periods")
following  press  releases by the  Company,  the Company  will issue  additional
shares of Common  Stock  ("Additional  Shares")  to  shareholders  of MEDTOX who
retain their shares of Common Stock through four specified dates (the "Repricing
Dates") to compensate the MEDTOX shareholders for decreases after the closing of
the MEDTOX  acquisition  in the market  price of the Common Stock of the Company
below $1.986 per share.  The Repricing Dates are the fifth trading day following
the  date  the  Registrant  issues  press  releases   announcing  its  financial
performance for the fiscal

<PAGE>


quarters ending on March 31, 1996, September 30, 1996 and September 30, 1997 and
the fiscal year ending on December  31, 1996 and the  Repricing  Periods are the
dates  between  the  dates  of the  press  releases  and  the  Repricing  Dates.
Accordingly,  the  number  of  Additional  Shares  issuable  in  the  future  in
connection  with the MEDTOX  acquisition  cannot be  determined at this time and
will depend upon changes in the market price of the Common Stock, as well as the
extent to which  MEDTOX  shareholders  retain the  MEDTOX  shares on each of the
Repricing Dates.

                  The  price protection  provisions  of the  Series A  Preferred
Stock  and the  MEDTOX  shareholders could  result in the Company being required
to  issue more  shares of Common  Stock than the Company is authorized to issue.
The Company's Certificate  of Incorporation  currently  authorizes the  issuance
of 30,000,000 million  shares of  Common Stock, of which  13,193,838 shares  are
currently issued and outstanding.  If all 407 outstanding shares of the Series A
Preferred  Stock were to be  converted at a 25% discount from the $1.875  market
price  of the  Company's Common Stock  on March 26, 1996,  14,471,111  shares of
Common Stock would be issuable upon conversion of the Series A  Preferred  Stock
and  only  2,335,051  shares  of  Common  Stock  would  be  available for future
issuances. 1,736,133 shares of Common Stock are issuable pursuant to outstanding
stock  options,  stock purchase plans and warrants. The Company's Certificate of
Incorporation  also  authorizes  the issuance of 1,000,000  shares of  Preferred
Stock  for which  the Board  of  Directors has the power to designate the rights
and  preferences,  of  which only 407 shares  are issued  and  outstanding.  The
Company  intends to  hold a  shareholders  meeting to  amend the Certificate  of
Incorporation  of  the Company  to increase the number of  authorized  shares of
Common Stock  of the Company,  which  additional  shares would  be  available to
satisfy the price  protection provisions of the Series A Preferred Stock and the
MEDTOX shareholders and for other corporate purposes.

                  The price  protection  provisions  of the  Series A  Preferred
Stock are  transferred  upon any transfer of the Series A Preferred  Stock,  but
terminate upon conversion of the Series A Preferred  Stock. The price protection
afforded the MEDTOX  shareholders  terminates  upon transfer of the Common Stock
issued to MEDTOX shareholders.

                  Other  shareholders  of the  Company  do not  have  the  price
protection  afforded  holders  of  Series  A  Preferred  Stock  and  the  MEDTOX
shareholders.  Accordingly,  if the  market  price  of the  Common  Stock of the
Company  declines,  the interests in the Company's  other  shareholders  will be
diluted  by the  price  protection  provisions  afforded  holders  of  Series  A
Preferred  Stock and the  MEDTOX  shareholders.  Substantial  sales of shares of
Common  Stock by the MEDTOX  shareholders  or  purchasers  of Series A Preferred
Stock or other  shareholders  may have a material  adverse  effect on the market
price of the Common  Stock of the  Company,  which would  increase the number of
Additional Shares issuable to MEDTOX shareholders on the Repricing Dates and the
number of shares  of Common  Stock  issuable  upon  conversion  of the  Series A
Preferred Stock.

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

General

                  The Company  commenced  operations in June 1983 and until 1986
was a development  stage company.  The Company became engaged in the manufacture
and sale of culture media, animal blood products,  customer antisera,  and other
Conventional  Biodiagnostic  Products as a result of its  acquisition of Granite
Technological Enterprises,  Inc. in June 1986. The Company began the manufacture
and sale of its EZ-SCREEN  diagnostic  tests in 1985 and introduced its patented
one-step  assay,  VERDICT and RECON,  in 1993.  On February 11, 1994 the Company
completed the acquisition of PDLA, which is now a wholly-owned subsidiary of the
Company.  The results of operations for the year ended December 31, 1994 include
the results  from  operations  of PDLA for the period  February 12, 1994 through
December 31, 1994. Since inception, the Company has financed its working capital
requirements primarily from the sale of equity securities.

Year Ended December 31, 1995 Compared to Year Ended December 31, 1994

                  Total  revenues for year ended December 31, 1995 increased 14%
to  $7,526,000,  compared to  $6,593,000  for the prior year.  This  increase is
primarily fully  attributable to the increase in revenues from sales of products
and  services  for 1995. These revenues totaled  $7,037,000,  an increase of 14%
compared to $6,183,000 for the prior year.

                  Laboratory  Service  Revenues for the year ended  December 31,
1995 were $4,312,000, an 18% increase compared to $3,647,000 for the prior year.
This  increase was due  primarily  to the efforts of a full sales and  marketing
force for the  laboratory  services of PDLA.  During the year ended December 31,
1994, the company realized sales of $566,000 from laboratory  services that were
transferred to American Medical Laboratories,  Inc. ("AML") in January 1995 and,
as such,  are not  included in the sales for the year ended  December  31, 1995.
Accordingly,  the increase in Laboratory  Service revenue  excluding those sales
transferred to AML was actually $1,231,000.

                  Product sales include the sales generated from substance abuse
testing products, which incorporates the EZ-SCREEN and VERDICT on site tests and
other  ancillary  products for

<PAGE>


the detection of abused  substances.  Sales from these products were $1,180,000,
down 9% compared to  $1,293,000  for the prior year.  The Company  believes this
decrease was primarily due to increased competition. This competition was caused
by the  introduction of several  products by competitors  which compete with the
products  of the  Company.  The  decrease  was  also  affected  by the lack of a
complete product line of the VERDICT products.

                  Product  sales also include sales of  agricultural  diagnostic
products  which are marketed  through  diAGnostix,  inc. Sales of these products
were  $1,090,000  for the year ended  December  31,  1995,  an  increase  of 35%
compared to sales of  $805,000  for the prior year.  The  acquisition  of Bioman
Products Inc. on June 1, 1995 brought  $404,000 in sales revenues to the Company
for the year  ended  December  31,  1995.  Excluding  these  revenues,  sales of
agricultural  diagnostic  products  were  $686,000  for 1995,  a decrease of 15%
compared to 1994. The Company believes this decrease is due to decreased testing
by customers of the Company.

                  Sales of  Microbiological  and  associated  product  sales and
contract  manufacturing  services were $393,000 for the year ended  December 31,
1995,  down 10%  compared to $438,000  for these  products and services in 1994.
This  decrease  was due to a reduced  marketing  effort.


                  In 1995,  the  Company completed  research and  development on
certain  tests  developed  for the U.S. Department  of Defense.  This enabled
production to begin for the first time on products specifically  manufactured
for the U.S. Department of Defense. Revenues from  shipment of these products
were $62,000 for the year ended  December 31, 1995.

                  Revenues  from  royalties  and  fees  during  the  year  ended
December 31, 1995 were  $300,000,  compared to $200,000 for 1994.  This increase
was primarily  due to the royalties  received from AML pursuant to the agreement
the Company has with AML.  Revenues  from interest and other income for the year
ended December 31, 1995 were  $189,000,  compared to $210,000 for the year ended
December 31, 1994.

                  The  overall  gross  margin  from  sales  for the  year  ended
December  31, 1995 was 6%,  compared to 2% of sales for the year ended  December
31,  1994.  Gross  margins  from the  sales of both  manufactured  and  products
purchased  for resale for the year ended  December 31, 1995 were 18% compared to
16% of sales of these  products  for the year  ended  December  31,  1994.

                  An increase in the number of samples  being  processed at PDLA
resulted in improved  gross margins for  laboratory  services for the year ended
December 31, 1995.  However, as in the year ended December 31, 1994, the cost of
providing  laboratory  services  exceeded  revenue realized from these services.
Since a large amount of the costs of providing  laboratory services are fixed or
near fixed  costs,  the margins  from sales of  laboratory  services  are volume
dependent.

                  Selling,  general  and  administrative  expenses  for the year
ended  December 31, 1995 were  $4,206,000,  compared to $3,341,000  for the year
ended  December  31,  1994.  This  increase  of 26% was  primarily  a result  of
increased sales and marketing expenses associated with

<PAGE>



the sale of the Substance Abuse Testing  Products and Services  marketed through
PDLA, the sales and marketing costs associated with former operations of Bioman,
as well as overall  increases  in the general  expenditures  resulting  from the
acquisition of PDLA.

                  Research and  development  expenses  incurred  during the year
ended  December  31, 1995 were  $920,000,  as compared to $729,000  for the year
ended  December 31,  1994.  This 26%  increase  was  primarily  due to increased
personnel  costs and  expenses,  as well as  increases  in work being  performed
pursuant to the DOD contract.

                  For the year ended  December  31, 1995,  the Company  incurred
interest  expense of $23,000,  compared to interest  expense of $25,000 incurred
during the year ended December 31, 1994.

   
                  The continued operating losses and negative cash flows
in 1995 of the PDLA operations resulted in an evaluation at year end of
the PDLA goodwill for possible impairment. The Company determined that the
operations of PDLA did not have long-term future viability as a stand-alone
laboratory operation and would not be supported by the Company on a
stand-alone basis. The underlying factors contributing to the financial
results for PDLA include competitive pricing pressures in the marketplace
and the inability of the Company to generate sufficient PDLA business volume
that would result in positive cash flows and profitable operations as a
stand-alone laboratory operation. The Company performed an analysis of the
PDLA undiscounted cash flows and projected that PDLA would have negative
cash flows for the foreseeable future. The Company determined that the
estimated shortfall of cash flows exceeded the carrying value of the
remaining PDLA goodwill, and as a result, recorded a write-off of $3,073,000
at December 31, 1995. The noncash write-off of goodwill will reduce the
future amortization expense of the Company by $173,000 per year.

                  As a result  of the  above,  the net  loss for the year  ended
December 31, 1995 was $7,285,000  compared to the net loss of $3,546,000 for the
year ended December 31, 1994.

                  At December 31, 1995 and in connection with the acquisition
of MEDTOX, the Company determined that it would consolidate the laboratory
operations of PDLA into the laboratory operations at MEDTOX. In addition, the
Company decided to down size certain administrative positions at both PDLA
and MEDTOX in order to eliminate duplicative functions. As a result of this
restructuring plan, the Company will record a charge of $858,000 in the first
quarter of 1996 to cover certain costs of the restructuring.
    

                  Management   believes  the   acquisition  of  MEDTOX  and  the
restructuring  of the  laboratory  operations  will  significantly  improve  the
operating  results of the  Company  although  there can be no  assurance  of the
success of the consolidation of the laboratory  operations in reducing costs and
improving  efficiencies.  Management  expects  net  sales to grow  through  both
additional  strategic  acquisitions  and the addition of new accounts as well as
the introduction of new products.

Year Ended December 31, 1994 Compared to Year Ended December 31, 1993

                  Total  revenues for the year ended December 31, 1994 increased
150% to $6,593,000, compared to $2,633,000 for the year ended December 31, 1993.
This increase is primarily attributable to an increase in revenues from sales of
products and services.  These revenues totaled  $6,183,000,  an increase of 169%
compared to $2,295,000 for the prior year.  The  acquisition of PDLA in February
of 1994  brought  total  revenues  of  $3,775,000  to the

<PAGE>


Company for year ended December 31, 1994 of which,  $3,647,000  were  laboratory
service revenues.  Excluding the PDLA revenues,  total revenues for 1994 were up
7% to $2,818,000  compared to $2,633,000 for 1993, and total product and service
revenues increased 11% to $2,536,000 compared to $2,295,000 for 1993.

                  Laboratory  Service  Revenues for the year ended  December 31,
1994 were  $3,647,000.  These revenues did not exist for the Company in 1993. By
acquiring  PDLA in  February of 1994,  the Company was able to offer  laboratory
services as a  complementary  product to the substance  abuse  testing  products
already  marketed by the Company.  As a result of the  acquisition,  the Company
recognized  almost eleven months of revenues  generated  through the  laboratory
services of PDLA.

                  Product sales include the sales generated from substance abuse
testing  products.  Sales from these  products were  $1,293,000 for the year end
December 31, 1994, an 18% increase  compared to  $1,093,000  for the prior year.
This  increase  is the  result  of  increased  sales  of the  on-site  products,
particularly VERDICT, in 1994.

                  Product  sales also include sales of  agricultural  diagnostic
products  consisting  of  EZ-SCREEN  test kits (for  mycotoxin  detection,  drug
residue  surveillance,   etc.),  species  identification  kits,  other  bioassay
technology  products  and third party  products.  These  products  are  marketed
through  diAGnostix,  inc.  Sales of these  products  were $805,000 for the year
ended December 31, 1994, an increase of 7% compared to sales of $751,000  during
the prior year.  This increase was due to the increased  purchases by the United
States Department of Agriculture  ("USDA") pursuant to two contracts the Company
has with the USDA, as well as regaining the sulfa-on-site test kit business from
an international customer which did not occur during the year ended December 31,
1993.

                  Microbiological   and  associated   product  sales   including
contract  manufacturing  were  $438,000  for the year ended  December  31,  1994
compared to $445,000  for these  products in 1993.  This  decrease  was due to a
reduced marketing effort.

                  Revenues  from  royalties  and  fees  during  the  year  ended
December 31, 1994 were $200,000,  compared to $257,000 for 1993.  These revenues
decreased 22% as a result of the termination on October 12, 1993 of the contract
the Company had with Farnam Companies, Inc.

                  Revenues  from  interest  and other  income for the year ended
December 31, 1994 were $210,000, compared to $81,000 for the year ended December
31, 1993. This 159% increase was due to the recovery of debts owed by a customer
of laboratory services which had previously been written off.

                  The  gross  margin  from  overall  sales  for  the year  ended
December 31, 1994  was  2%,  compared  to  12%  of  sales  for  the  year  ended
December 31, 1993.   Excluding the effect of the PDLA acquisition  for the  year
ended  December 31, 1994,  the  gross margin would have been 16%. This increase
in gross margin excluding the effect of the PDLA acquisition is overshadowed by
the impact

<PAGE>

of the laboratory services provided through PDLA. As a large amount of the costs
of providing laboratory services are fixed or near fixed costs, the margins from
the sales of  laboratory  services are volume  dependent.  The volume of testing
performed by PDLA for the period ended December 31, 1994 was adversely  affected
by the loss of contracts before the acquisition of PDLA by the Company.

                  Selling,  general  and  administrative  expenses  for the year
ended  December 31, 1994 were  $3,341,000,  compared to $2,152,000  for the year
ended  December 31, 1993.  This 55% increase was primarily a result of increased
personnel  from the  acquisition of PDLA,  increased  expenses for the sales and
marketing of the substance abuse testing products,  the amortization of goodwill
arising from the acquisition of PDLA, and increases in other expenses due to the
acquisition of PDLA.

                  The  acquisition  of PDLA was accounted for under the purchase
method of accounting and the Company recorded goodwill of $3,394,000.  For 1994,
the Company amortized goodwill on a straight line basis over 20 years.

                  Research and  development  expenses  incurred  during the year
ended  December  31, 1994 were  $729,000,  as compared to $825,000  for the year
ended  December 31,  1993.  This 12%  decrease  was  primarily  due to decreased
expenses,  including  personnel  costs  associated  with the movement of certain
personnel from research and development to operations, and the lack of costs and
expenses associated with the Farnam contract which was terminated on October 12,
1993.  Research and  development  efforts are directed  toward  enhancements  of
existing  products,  as well as the  development  of new products  which in some
cases have been or are funded by outside parties.

                  For the year ended  December  31, 1994,  the Company  incurred
interest  expense of $25,000,  compared to interest  expense of $9,000  incurred
during the year ended December 31, 1993. This increase was primarily a result of
the Company borrowing funds against a line of credit.

                  During the year ended  December 31, 1993 the Company  incurred
expenses   of   $353,000   related   to  its   legal   disputes   with  DDI  and
Transia-Diffchamb  S.A. On August 10, 1993 the arbitrator's  decision in the DDI
dispute  awarded to DDI certain costs and legal fees.  The actual costs and fees
were later set at $336,000,  bringing the total to $689,000.  The Company had no
such expenditures during the year ended December 31, 1994.

                  As a result  of the  above,  the net  loss for the year  ended
December 31, 1994 was $3,546,000, compared to the net loss of $3,066,000 for the
year ended December 31, 1993.

Material Changes in Financial Condition

                  At December 31, 1995, cash and cash  equivalents were $258,000
compared to $1,105,000  as of December 31, 1994.  The decrease of $847,000 was a
result of several factors as discussed below.

<PAGE>

                  At December 31, 1995,  accounts  receivable  were  $1,029,000.
This 22% increase compared to $843,000 at December 31, 1994 was primarily due to
$113,000  in  receivable  generated  through  seven  months  of  sales  from the
acquisition  of Bioman  Products.  Excluding  the Bioman  receivables,  accounts
receivables  for the year ended  December  31, 1995  increased 9% over the prior
year.

                  The allowance  for doubtful  accounts at December 31, 1995 was
$130,000,  a decrease of 37% compared to $206,000  for the prior year end.  This
decrease was the result of the write-off for PDLA  customers for $70,000.  Also,
in 1995, the Company had fewer customers with receivables due over 90 days, thus
the allowance was not significantly adjusted to reflect the increase in accounts
receivable.

                  Inventories  were  $937,000 at December  31, 1995  compared to
$853,000 at December 31, 1994. This increase of $84,000 or 10% was primarily due
to an increase in work in process inventory related to the VERDICT product line.

                  Prepaid  expenses and other  assets were  $868,000 at December
31,  1995,  as  compared to $272,000 at  December  31,  1994.  This  increase of
$596,000 was  primarily  due to the costs  associated  with the  acquisition  of
MEDTOX  including  a $500,000  deposit  placed  into an escrow  account  pending
closing of the acquisition of MEDTOX.

                  During the year ended  December 31,  1995,  the Company took a
charge of $3,100,000 to write off the goodwill  associated  with the acquisition
of PDLA.  Accordingly,  the amount of goodwill at December 31, 1995 was $117,000
as compared to $3,247,000 at December 31, 1994. The remaining  goodwill  relates
to the acquisition of Bioman in June 1995.

                  At December 31, 1994, the Company had an  outstanding  balance
of  $850,000  on a line of credit  with a bank.  The  Company  repaid  the total
outstanding balance during the year ended December 31, 1995.

   
                  Accrued  expenses  were  $834,000  at  December  31, 1995 as
compared to  $347,000  at  December  31,  1994.  This  increase of $487,000  was
primarily due to expenses associated with the acquisition of MEDTOX.
    
                  As  described  more  fully  in  the  notes  to  the  financial
statements,  the Company  entered into a $125,021 loan  agreement with the North
Carolina  Biotechnology Center (NCBC). The loan, plus accrued interest,  was due
August 14, 1994.  On December 15, 1994,  the Company and NCBC  negotiated a loan
modification  extending  the due date to August  14,  1996.  In  addition,  NCBC
exercised  their right to convert  50%, or  approximately  $62,000,  of the loan
amount  into  16,100  shares of the  Company's  common  stock.  Accordingly,  at
September  30,  1995,  the Company  had a balance of loan  payable of $63,000 to
NCBC. In addition,  during 1995 the Company borrowed $100,000 from Dr. Samuel C.
Powell in the form of a 90 day promissory  note.  Primarily as a result of these
transactions,  the balance of notes payable at December 31, 1995 was $182,000 as
compared to $158,000 at December 31, 1994.

Liquidity and Capital Resources

                  Since its inception,  the working capital  requirements of the
Company  have been  funded  by cash  received  from  equity  investments  in the
Company.  At December 31,  1995,  the Company had cash and cash  equivalents  of
$258,000.  The Company had also deposited  $500,000 in an escrow account towards
the  acquisition  of MEDTOX.  On January 30,  1996,  the Company  completed  the
acquisition of MEDTOX.  To finance the acquisition of MEDTOX and provide working
capital,  the Company raised $20,350,000 from the sale of 407 shares of Series A
Preferred Stock and borrowed $5,000,000. The debt financing consists of two term
loans  totaling  $4,000,000 and up to $7,000,000 in the form of a revolving line
of  credit  based  primarily  on the  receivables  of  the  Company  (the  "Loan
Agreement").  The amount of credit  available  to the  Company  varies  with the
accounts receivable and the inventory of the Company.  The interest rates on the
two term loans of  $2,000,000  each are 2.5 points  above the prime rate and 2.0
points above the prime rate.  The revolving  line of credit  carries an interest
rate equal to 1.5 points  above the prime rate.  The Company  believes  that the
aforementioned  capital  will  be  sufficient  to  fund  the  Company's  planned
operations through 1996 and beyond,  although there can be no assurance that the
available  capital  will be  sufficient  to fund the  future  operations  of the
Company.

                  As of  December  31,  1995,  the  Company  had not  achieved a
positive cash flow from operations. Accordingly, the Company relies on available
credit arrangements,  outside funding of research and development, and continued
sales of its equity securities to fund operations until a positive cash flow can
be achieved.  Management believes that it has taken, and is prepared to continue
to take, the actions  required to yield a positive cash flow from  operations in
the future.

                  The  Company  believes  that the  acquisition  of MEDTOX,  the
consolidation  of the  laboratory  operations  from  PDLA to  MEDTOX,  and other
synergies  that will be realized from the  acquisition of MEDTOX will enable the
Company to generate  positive cash flow. The Company  continues to follow a plan
which includes (i) continuing to  aggressively  monitor and control costs,  (ii)
increasing revenue from sales of the Company's products,  services, and research
and development contracts, as well as (iii) pursuing synergistic acquisitions to
increase the Company's  critical mass.  There can be no assurance that costs can
be   controlled,   revenues  can  be  increased,   financing  may  be  obtained,
acquisitions successfully consummated, or that the Company will be profitable.

                  During 1995,  the Company sold a total of 2,140,963  shares of
common stock in 13 separate  private  transactions.  The sale of these 2,140,963
shares generated net proceeds of $3,884,109 to the Company.

<PAGE>

                  As mentioned  above, the Company sold 407 shares of its Series
A Preferred  Stock for  $20,350,000  in 1996.  Also in 1996,  the  Company  sold
235,295 shares of its common stock to a director in a private  transaction.  The
sale of these 235,295 shares generated proceeds of $600,002 to the Company.

                   Notes to Consolidated Financial Statements

                                December 31, 1995


1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

The consolidated financial statements include the accounts of EDITEK, Inc.
("EDITEK") and its wholly-owned subsidiaries, Princeton Diagnostic Laboratories
of America, Inc. ("PDLA") and diAGnostix, Inc. (collectively referred to as "the
Company"). EDITEK is engaged in the research, development and sale of products
based upon enzyme immunoassay technology for the detection of antibiotic
residues, mycotoxins, drugs of abuse and other hazardous substances. PDLA
provides clinical testing services for the detection of substances of abuse and
diAGnostix, Inc. distributes agridiagnostic and food safety testing products.
All significant intercompany transactions and balances have been eliminated.

TRADE ACCOUNTS RECEIVABLE

Sales are made to local, national and international customers including
livestock producers, food processors, veterinarians, government agencies,
medical professionals, corporations, law enforcement agencies and healthcare
facilities. Concentration of credit risk is limited due to the large number of
customers to which the Company sells its products and services. The Company
extends credit based on an evaluation of the customer's financial condition and
receivables are generally unsecured. The Company provides an allowance for
doubtful accounts equal to the estimated losses expected to be incurred in the
collection of accounts receivable.

INVENTORIES

Inventories are valued at the lower of cost (first-in, first-out method) or
market. At December 31, 1995 and 1994, the inventory included a reserve of
$12,000 and $25,000, respectively, for lower of cost or market and for
obsolescence.

EQUIPMENT AND IMPROVEMENTS

Equipment and improvements are stated at cost. Provisions for depreciation have
been computed using the straight-line method to amortize the cost of depreciable
assets over their estimated useful lives. Leasehold improvements are amortized
over the lesser of the lease term or the economic useful lives of the
improvements.

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

REVENUE RECOGNITION

Sales are recognized in the statement of operations when products are shipped or
services are rendered.

ROYALTIES AND FEES

The Company receives reimbursement for certain research and development costs.
The reimbursement is recorded as royalties and fees.

RESEARCH AND DEVELOPMENT

Research and development expenditures are charged to expense as incurred.

INCOME TAXES

The Company uses the liability method of accounting for income taxes. Under this
method, deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash and highly liquid investments maturing
within three months when purchased.

LOSS PER SHARE OF COMMON STOCK

Loss per share of common stock amounts are based on the weighted average number
of shares of common stock outstanding. All other common stock equivalents,
including convertible debt disclosed in Note 4, were anti-dilutive and therefore
were not included in the computation of loss per share, for all periods
presented.

RELATED PARTY TRANSACTIONS

The Company has transactions with related parties. The specific transactions are
disclosed in the applicable notes to the financial statements.

             Notes to Consolidated Financial Statements (continued)


1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

GOODWILL

Goodwill is amortized on a straight-line basis over 20 years. The carrying value
of goodwill is reviewed if the facts and circumstances suggest that it may be
impaired. If this review indicates that goodwill will not be recoverable, as
determined based on the undiscounted cash flows of the entity acquired over the
remaining amortization period, the Company's carrying value of the goodwill is
reduced by the estimated shortfall of cash flows (see Note 3).

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

RECENTLY ISSUED ACCOUNTING STANDARD

In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed of," which requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. Statement 121 also addresses
the accounting for long-lived assets that are expected to be disposed of. The
Company will adopt Statement 121 in the first quarter of 1996 and, based on
current circumstances, does not believe the effect of adoption will be material.

RECLASSIFICATIONS

Certain reclassifications have been made to the years 1994 and 1993 to conform
with the 1995 presentation. Such reclassifications had no effect on previously
reported net loss or accumulated deficit.

2.    ACQUISITIONS

In January, 1996, the Company acquired MEDTOX Laboratories, Inc., ("MEDTOX") a
toxicology laboratory located in St. Paul, Minnesota. The purchase price was $24
million, which included $19 million cash and the issuance of 2,517,306 shares of
common stock. The acquisition was accounted for under the purchase method of
accounting wherein the Company recognized approximately $22 million of goodwill.
The goodwill is being amortized over a period of 20 years.

The Company financed the acquisition by issuing $19 million of convertible
preferred stock and borrowing $4 million under two $2 million term loans. The
Company also entered into a revolving line of credit of up to $7 million for
working capital purposes.

At December 31, 1995, the Company had $500,000 in an escrow account as a
required deposit toward the MEDTOX acquisition.

The following unaudited proforma information presents the results of operations
of the Company and MEDTOX for the year ended December 31, 1995, as if the
acquisition had been consummated as of January 1, 1995.

      Revenues                         $27,745
      Net loss                         $ 4,459
      Net loss per share               $  (.37)


On June 1, 1995, the Company acquired Bioman Products, Inc., ("Bioman") an
environmental diagnostics company. The purchase price was $140,000, which
included cash and the issuance of 21,489 shares of common stock. The acquisition
was accounted for under the purchase method of accounting wherein the Company
recognized $117,000 of goodwill, which is being amortized over a period of 20
years. The consolidated results of operations for the year ended December 31,
1995 included the results of the Bioman operations from June 1, 1995 to December
31, 1995.

The Company acquired PDLA on February 11, 1994 by issuing 826,790 shares of its
common stock in exchange for all of the outstanding shares of PDLA's stock. The
total value of the exchange was $3,876,000. The acquisition was accounted for
under the purchase method of accounting and the Company recorded goodwill of
$3,394,000. Additional shares of common stock were subsequently issued to former
major shareholders of PDLA through price protection agreements. The consolidated
results of operations for the year ended December 31, 1994 include the results
of the PDLA

operations from February 12, 1994 to December 31, 1994 (see Note 3).

   
3.    GOODWILL WRITE-OFF

The continued operating losses and negative cash flows of the PDLA operations
resulted in an evaluation during the fourth quarter of 1995, of the PDLA
goodwill for possible impairment. The Company determined that the operations
of PDLA did not have long-term future viability as a stand-alone laboratory
operation and would not be supported by the Company on a stand-alone basis.
The underlying factors contributing to the financial results for PDLA include
competitive pricing pressures in the market place, the loss of preacquisition
customers and the inability of the Company to generate sufficient PDLA
business volume that would result in positive cash flows and profitable
operations. The Company performed an  analysis of the PDLA undiscounted cash
flows over the remaining amortization period and determined that the estimated
shortfall of cash flows exceeded the carrying value of the remaining PDLA
goodwill. As a result the Company recorded a write-off of goodwill of
$3,073,000 at December 31, 1995.
    

4.    DEBT

On August 15, 1989, the Company entered into a long-term loan agreement with a
state funded, non-profit organization whereby the Company borrowed an aggregate
of $125,000 to fund the development cost of a test for Chlamydia, a sexually
transmitted disease. The loan originally had an interest rate of seven and one
half percent (7.5%) per annum with all principal and interest due on August 15,
1994. The Company amended the loan agreement on the due date and issued 16,100
shares of common stock as repayment for $62,000 of the loan. The remaining
principal, $63,000, now bears interest at the rate of nine percent (9%) per
annum; this principal and interest, which are due on August 15, 1996, are
convertible into shares of common stock.

On March 1, 1994, the Company entered into a line of credit arrangement for up
to $1,000,000 at an interest rate of 5.82%. The line-of-credit was repaid and
terminated in 1995.

On December 18, 1995, the Company borrowed $100,000 from a Director at an
interest rate of 10.5%. The Company repaid the principal and interest in
February, 1996.

  Net operating loss carryforwards                   11,271,000       9,805,000
  Research and experimental credit carryforwards        456,000         426,000
  Uniform capitalization reserve                         22,000            --
  Restructuring costs                                   157,000            --
  Other                                                  63,000          26,000
Total deferred tax assets                            12,460,000      10,653,000

Total deferred tax assets                                 6,000           7,000
Net deferred tax assets(liabilities)               $       --      $       --


During 1995 and 1994, the valuation allowance increased by $1,808,000 and
$2,644,000, respectively.

At December 31, 1995, the Company has available to offset future taxable income
for financial reporting and federal tax purposes, operating loss carryforwards
of approximately $29,488,000 expiring in 1998 through 2009. Research and
experimental credits of approximately $456,000, expiring in 1998 through 2009,
are also available to offset future income tax liabilities.

The Company acquired approximately $2,473,000 in net operating loss
carryforwards when it purchased PDLA. This amount is included in total net
operating loss carryforwards described in the preceding paragraph. Future use of
this carryforward will be limited based on the Separate Return Limitation Year
("SRLY") Rules found in Proposed Treasury Regulation 1.1502-21(c). These rules
limit the use of a net operating

loss carryforward into consolidated return years. The limitation, computed
annually, limits the use of the SRLY net operating loss carryforward to the
cumulative annual taxable income generated by the purchased company since its
admittance into the consolidated group.

The annual usage of the Company's net operating loss carryforwards has been
limited by provisions of the Tax Reform Act of 1986 ("TRA"). Under TRA, if a
company experiences a change in ownership of more than 50% (by value) of its
outstanding stock over a three year period, the use of its pre-change in
ownership net operating loss carryforwards will be limited each year until the
loss is exhausted or the carryover period expires. Such a change in ownership
occurred at the time of the Company's 1987 public stock offering.

The amount of pre-change in ownership net operating loss carryforwards of
$8,500,000 which can be utilized to offset future federal taxable income will be
approximately $2,300,000 per year. TRA does not limit annual usage of
post-change in ownership net operating loss carryforwards.

   
9.    ARBITRATION COSTS

During the latter part of 1992 and through 1993, the Company was involved in
arbitration matters with Transia-Diffchamb and Disease Detection International
("DDI"). In the Transia-Diffchamb arbitration case, the arbitrator ruled on July
30, 1993 in favor of the Company; however, the Company was not able to recover
any legal fees. In the DDI arbitration case, the arbitrator ruled against the
Company. The arbitrator also ruled that DDI was entitled to recover costs and
related legal fees. The Company has recognized an expense of $689,000 for these
costs and fees.
    

10.   MAJOR CUSTOMERS

Sales to major customers and foreign sales amounted to the following percentages
of total revenue:

approximately $6 million available on its revolving line of credit (see Note 2).

On January 31, 1996, the Company sold 235,295 shares of common stock to a
Director of the Company. Proceeds from the sale were $600,000.

   
12.   RESTATEMENT

The Company has restated its 1995 financial statements to eliminate $758,000 of
restructuring costs associated with the acquisition of MEDTOX. The restatement
resulted in reductions of the previously reported net loss, certain accrued
liabilities and accumulated deficit by $758,000. Additionally, the 1995 net loss
per share has been reduced from $.85 per share to $.77 per share. The Company
will record the restructuring costs in the first quarter of 1996, to comply
with EITF 95-14 as the consummation date of the acquisition of MEDTOX was
determined to be January 30, 1996.

                  The following  unaudited pro forma consolidated  balance sheet
as of December 31, 1995, and the unaudited pro forma consolidated  statements of
operations for the year ended December 31, 1995 gives effect to the  acquisition
of  MEDTOX  by  EDITEK  using  the  purchase  method.  The  unaudited  pro forma
consolidated   financial  information  is  based  on  the  historical  financial
information  of EDITEK  and  MEDTOX as of  December  31,  1995 and the pro forma
adjustments  described in the notes thereto.  There are no pro forma adjustments
to other amounts reflected in the historical  financial  statements of MEDTOX as
management  believes  that the  historical  costs  assigned to MEDTOX assets and
liabilities approximate fair value.

                  Information was prepared as if the acquisition was effected as
of December 31, 1995 in the case of the unaudited pro forma consolidated balance
sheet  and as of  January  1,  1995  in the  case  of the  unaudited  pro  forma
statements of operations.  The unaudited pro forma financial  statements may not
be  indicative  of  the  results  that  actually  would  have  occurred  if  the
acquisition  had been in effect on the dates  indicated or which may be obtained
in the future.  The unaudited pro forma financial  information should be read in
conjunction with the financial statements and other financial data of EDITEK and
MEDTOX included herein.

      The interest rates on the loans are as follows:

          Term Loan B                       2.5% above Prime Rate

     the fair value of the  identifiable net assets of MEDTOX has been reflected
     and is comprised of the following:

                                          (dollar amounts in thousands)

                           Purchase price                              $24,000
