                                     PART I

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.

                  The Company does not expect to file a  registration  statement
with  respect to shares  sold  pursuant to  Regulation  S.  Therefore,  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. The Company believes such legends will not
prevent legitimate trading of its stock. A number of holders of Series A 
Preferred Stock have threatened litigation over the Company's decision. The 
Company and its Preferred shareholders have commenced discussions through the
placement agent for the Preferred offering about ways to address the concerns
of the Company without unduely delaying stock transfers that are in compliance
with securities laws. There can be no assurance, however, that such discussions
will result in an acceptable agreement between the Company and the holders of
its Series A Preferred Stock.

                  In  connection  with the  acquisition  of MEDTOX,  the Company
issued  2,517,306  to the former  shareholders  of MEDTOX and sold 103 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 103 shares of Series A Preferred  Stock were  included on a  Registration
Statement  on Form S-3 which was filed on  February  9, 1996.  The 103 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 2.  PROPERTIES.

                  The Company leases approximately 33,000 square feet in 
Burlington, North Carolina, where it maintains its executive offices, research
and development laboratories, production operations, and warehouse. The total
rent paid by the Company for this site during the fiscal year ended December 31,
1995 was approximately $119,000. These facilities are currently leased from Dr.
Samuel C. Powell, a member of the Board of Directors of the Company, at a
rental of approximately $10,000 per month, plus a pro rata share of utilities 
and certain other expenses. In June 1989, the Company executed a lease agreement
with Dr. Powell for a term of one year ending May 31, 1990. The Company  
subsequently acquired an option to extend the lease for an additional one-year
period after the expiration of such term on May 31, 1990. The option to extend 
the lease has not been exercised and the  Company is currently leasing the
space on a month-to-month basis. The Company intends to negotiate a new lease 
with Dr. Powell in the future. The Company believes it is renting these
facilities on terms as favorable as those available from third parties for 
equivalent premises. The Company also holds certain rights of first refusal to 
lease additional space in the building if it becomes available (the building 
contains a total of 42,900 square feet). In the opinion of management,  
comparable alternative facilities could be obtained without disruption of its
business if a new lease with Dr. Powell is not negotiated. See "Item 13 - 
Certain Relationships and Related Transactions."

<PAGE>

                  The  Company  also  leases  a farm  in  Warren  County,  North
Carolina  from Warren Land Company  ("WLC") a company in which Dr. Powell owns a
12% interest and certain  members of Dr.  Powell's  family and their  respective
families own the  remainder for the purposes of  maintaining  animals to produce
antibodies and for research and  development.  The  arrangement  for use of this
facility  is on a  month-to-month  basis at a cost of $2,797 per  month.  In the
opinion of  management,  comparable  alternative  facilities  could be  obtained
without  disruption  of its business if this facility  were not  available.  See
"Item 13 - Certain Relationships and Related Transactions."

                  The  Company  leases  administrative  offices  and  laboratory
facilities in an approximately  22,000 square foot facility in South Plainfield,
New Jersey.  The facility was built and equipped in 1985. The facility is rented
under a lease  which  expired  in May of 1995.  In  February  1995  the  Company
negotiated a  modification  to the current lease which extends the lease through
the year 2000 with one five year  option to renew.  The new rent  payment  which
commenced on May 1, 1995 is $170,345 per year which is a 32% reduction  from the
annual rent of $250,908 prior to May 1, 1995. In addition,  the Company received
$100,000  from  the  landlord  to  amend  the  lease  in New  Jersey.  Upon the
completion of the transition of the laboratory  operations  from PDLA to MEDTOX,
the Company  will  utilize  approximately  30% of the  existing  facility in New
Jersey  for  a  courier  system,   customer  service  and  other  administrative
functions.  The  remaining  70% of the  facility  will  become idle and has been
considered in the Company's restructuring charge. See Note 3 to the Notes of the
Consolidated Financial Statements contained herein.

                  The Company also leases a 1,700 square foot warehouse facility
in Mississauga, Ontario where the Canadian sales and distribution operations
of diAGnostix, inc. are based. The space is rented under a lease which expires
in July 1998. The current lease payment is approximately $4,800 per year.

                  The administrative offices and laboratory operations of MEDTOX
are located in a 41,017 square foot facility in St. Paul, Minnesota. The 
facility is rented under a lease which expires in March 1997. The current 
annual rent for the facility is $330,000 per year.

                  The Company believes that its existing facilities are adequate
for the  purposes  being  used  to  accommodate  its  product  development,  and
manufacturing and laboratory testing requirements.

ITEM 5.  MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER 
         MATTERS.

Common Stock

                  Since  September 27, 1993, the Common Stock has been listed on
the American Stock Exchange  trading under the symbol "EDI".  From September 16,
1992 to  September  26,  1993 the  Common  Stock was traded in and quoted in the
Emerging  Company  Marketplace of the American Stock Exchange  ("ECM") under the
trading symbol "EDI.EC".  The Common Stock had  historically  been traded in the
over-the-counter market and was quoted in the National Association of Securities
Dealers Automated Quotation System ("NASDAQ").  On June 5, 1992 the Common Stock
was delisted  from NASDAQ as a result of  non-compliance  with  revised  listing
requirements.  As a result,  from June 8, 1992  through  September  15, 1992 the
Common  Stock  was  traded  on and  quoted  in the  Non-NASDAQ  Over-The-Counter
Bulletin  Board.  As of March 19,  1996,  the number of holders of record of the
Common  Stock was  2,895.  The  following  tables set  forth,  for the  calendar
quarters  indicated,  the high and low  closing  price per share for the  Common
Stock, as reported by the American Stock Exchange or the high and low bid prices
per share for the Common  Stock as  reported  by NASDAQ.  The  quotations  shown
represent inter dealer prices without  adjustment for retail markups,  markdowns
or commissions, and do not necessarily reflect actual transactions:

                  On March 26,  1996,  the closing  price of the Common Stock as
reported by the American Stock Exchange was $1.875.

                  No dividends  have been  declared or paid by the Company since
its inception.

<PAGE>

                  The Company's loan  agreements  prohibit cash dividends on the
Common Stock of the Company and limit the Company's  ability to pay dividends on
the Series A Preferred  Stock of the Company to dividends paid after February 1,
1997 that do not exceed one third of the excess cash flow of the Company for the
previous year as defined in the loan agreement.

Series A Preferred Stock

                  To help finance the  acquisition of MEDTOX and provide working
capital, the Company issued 407 shares of Series A Preferred Stock.

                  The Series A  Preferred  Stock is  convertible  into shares of
Common Stock,  at any time from March 30, 1996, the 60th day after the shares of
Series A  Preferred  Stock  were  first  issued  by the  Company  (the  "Initial
Conversion Date"), until January 30, 1998, the second anniversary of the Initial
Preferred  Issuance Date, at which time all conversion  rights terminate and any
remaining shares of Series A Preferred Stock will be automatically converted, at
a rate  determined by a formula based on a discount from the market price of the
Common  Stock at the time of  conversion,  unless  the  holder of such  Series A
Preferred  Stock  notifies the Company not to convert such shares.  The Series A
Preferred Stock has no voting power and has certain  liquidation  preference and
dividend  rights.  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
the lesser of (i) $2.775 or (ii) 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.

                  The Series A Preferred Stock will accrue an annual dividend of
Four  Thousand  Five  Hundred   ($4,500)   Dollars  per  share  (the  "Preferred
Dividend"). Such Preferred Dividend shall be payable when and as declared by the
Board of Directors in its sole discretion.  The Preferred Dividend is cumulative
until December 31, 1997.  Dividends accruing after December 31, 1997 will not be
cumulative.  No  dividend  shall be  payable  on shares  of Common  Stock of the
Company until all accrued cumulative unpaid dividends are paid to holders of the
Series A Preferred Stock.

ITEM 6.  SELECTED FINANCIAL DATA.

                  The  following   selected  financial  data  are  derived  from

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.

Effects of MEDTOX Acquisition

                  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  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 has taken a charge of $731,000 to cover  certain costs of the
restructuring.  The Company had no such charge in 1994.  See Note 3 of the Notes
to the Consolidated Financial Statements contained herein.

                  With   the   subsequent   consolidation   of  the   laboratory
operations,  the Company has written off the  remaining  amount of goodwill that
was recorded from the  acquisition of PDLA in 1994. This resulted in a charge of
$3,100,000  for the year ended December 31, 1995. The Company had no such charge
for the year ended December 31, 1994.

                  As a result  of the  above,  the net  loss for the year  ended
December 31, 1995 was $8,043,000  compared to the net loss of $3,546,000 for the
year ended December 31, 1994.

                  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  $1,202,000  at  December  31, 1995 as
compared to  $347,000  at  December  31,  1994.  This  increase of $855,000  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.

<PAGE>

                  At December 31,  1995,  the Company  accrued  $626,000 for the
payment of certain  restructuring costs associated with the consolidation of the
laboratory  operations  of PDLA with the  laboratory  operations  of MEDTOX.  At
December 31, 1994, the Company had no accrual for restructuring costs.

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.

(1)      Options to acquire an  aggregate  of 340,742  shares of Common Stock of
         the Company were granted to all  employees  during 1995.  No options to
         acquire  Common  Stock were  granted to  non-employee  directors of the
         Company during 1995. No stock  appreciation  rights were granted to the
         named executive officers during 1995.

<PAGE>

(2)      The  potential  realizable  value of the  options  reported  above  was
         calculated by assuming 5% and 10% annual rates of  appreciation  of the
         Common Stock of the Company from the date of grant of the options until
         the   expiration  of  the  options.   These  assumed  annual  rates  of
         appreciation  were used in compliance  with the rules of the Securities
         and Exchange  Commission and are not intended to forecast  future price
         appreciation of the Common Stock of the Company.  The Company chose not
         to report the present  value of the  options,  which is an  alternative
         under  Securities and Exchange  Commission  rules,  because the Company
         does not believe any formula will determine with reasonable  accuracy a
         present  value based on unknown or volatile  factors.  The actual value
         realized from the options could be  substantially  higher or lower than
         the values  reported above,  depending upon the future  appreciation or
         depreciation  of the Common  Stock  during  the  option  period and the
         timing of exercise of the options.

(3)      Options were granted on July 25, 1995, October 2, 1995, and December 
         13, 1995. 25,000 of the options granted to Mr. Skinner, 15,000 of the 
         options granted to Dr. Golden, 17,660 of the options granted to Mr. 
         Heath, and 3,190 of the options granted to Mr. Terretti became
         vested and  exercisable  quarterly  over a three year  period in twelve
         equal installments commencing three months after the grant date.

(1)  The closing price of the Common Stock of the Company at December 31, 1995
 was $2.88 per share.

Long-Term Incentive Plans and Pension Plans

         The Company does not  contribute  to any  Long-Term  Incentive  Plan or
Pension Plan for its executive  officers as those terms are defined in the rules
of the  Securities  and  Exchange  Commission.  The Company  relies on its stock
option plans to provide long-term incentives for executive officers. The Company
has two stock option plans, an equity compensation plan which was adopted by the
shareholders  of the annual meeting in 1993 to replace the 1983 Incentive  Stock
Option Plan which  expired on June 23, 1993 and a 1991  Non-Employee  Director's
Plan for members of the Board of Directors who are not employees of the Company.
The Company has also granted options to James D. Skinner outside these plans.

Compensation of Directors

<PAGE>

         In 1995 each  director  who is not an employee of the Company  received
$10,000 as a payment for the year 1995.  All directors are also  reimbursed  for
expenses incurred in attending Board of Directors  meetings and participating in
other activities.

Employment Contracts

         James D.  Skinner,  the  Chairman  of the  Board,  President  and Chief
Executive Officer of the Company,  has an employment  agreement with the Company
covering  the  period  ending  June 30,  1990,  which by its  terms is  extended
thereafter in one-year  increments  unless  otherwise  terminated  due to death,
permanent  disability,  change in control of the  Company  or for  "cause".  The
employment agreement,  as amended on July 1, 1988, provides for an annual salary
of at  least  $135,000  and  certain  fringe  benefits  including  a  disability
insurance  policy, a life insurance policy on Mr. Skinner for the benefit of his
named  beneficiary in the amount of $1,000,000 and automotive  expenses.  During
1994, the Company paid insurance  premiums  aggregating $4,078 for Mr. Skinner's
disability  insurance and $4,285 for Mr.  Skinner's  life insurance and paid Mr.
Skinner an auto  allowance of $8,800,  none of which are  included  under Annual
Compensation in the Summary  Compensation Table set forth above. In the event of
a termination  of Mr.  Skinner's  employment by the Company  without cause or by
reason of a "change in  control"  of the  Company,  Mr.  Skinner is  entitled to
receive  severance  pay equal to his then current  annual  salary.  A "change in
control" is defined as (i) the  acquisition of control by any person or group of
capital stock  representing 50% or more of the Company's voting stock,  (ii) the
approval of the Company of a merger or consolidation in which the Company is not
the surviving entity,  (iii) the agreement by the Company to sell  substantially
all of its assets to a third party unless the third party is  controlled  by the
Company and Mr. Skinner continues as its President and Chief Executive  Officer,
(iv) the approval by the Company of a plan of liquidation of the Company, or (v)
the  election of  directors  constituting  more than  one-half of the Board who,
prior to their election,  were not elected or nominated for election by at least
a majority of the Board of Directors.

         Upon a change of control or termination of Mr. Skinner's employment for
any reason other than death or permanent  disability,  the  non-qualified  stock
options granted to Mr. Skinner pursuant to the terms of his employment agreement
will immediately vest. On September 10, 1988 Mr. Skinner borrowed funds from the
Company to exercise  nonqualified  stock  options to purchase  13,334  shares of
Common Stock for an exercise price of $7.50 per share granted to him pursuant to
his employment  arrangement.  The terms of the loan are described under "Certain
Relationships and Related  Transactions - Loan to James D. Skinner." Pursuant to
his  employment  arrangement,  Mr. Skinner holds  nonqualified  stock options to
purchase  26,666 shares of Common Stock for an exercise price of $3.75 per share
which  expire on May 4, 2000 and 33,334  shares of Common  Stock for an exercise
price of $3.75 per share which expire on May 4, 2000.  Mr. Skinner has the right
to require the Company to loan him the exercise  price for 26,666  shares on the
same terms as the loan described above.

Compensation Committee and Decision Making

<PAGE>

                  The  compensation  (other  than stock  options)  of  executive
officers of the Company was determined by the Compensation  Committee consisting
of Gene E. Lewis,  and Samuel C. Powell.  Mr. James D.  Skinner,  the  Chairman,
President  and  Chief   Executive   Officer  of  the  Company   participated  in
deliberation  of the Board of Directors  concerning  compensation  for executive
officers other than himself.  Messrs.  Powell and Skinner have also entered into
other  transactions  with the Company.  See "Certain  Relationships  and Related
Transactions."

         Stock options are awarded  under the Company's  1983 Stock Option Plan,
the Equity  Compensation  Plan and Non-Employee  Director Plan by a stock option
committee  consisting  of the  nonemployee  members  of the Board of  Directors:
Samuel C. Powell,  and Gene E. Lewis,  who are eligible to receive stock options
under the  Company's  1991  Non-Employee  Director  Plan.  The  number of shares
issuable pursuant to options granted under the Non-Employee Stock Option Plan is
determined by dividing the aggregate  award of $10,000 by the exercise  price of
the options,  which was the fair market value of the  Company's  Common Stock on
the date of the award.

ITEM 12.      SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

The following table sets forth information  available to the Company as of March

ITEM 13.          CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

<PAGE>

Lease Agreement with Dr. Samuel C. Powell

         In July 1986,  the Company  executed a lease  agreement with Dr. Powell
providing  for a lease to the  Company of  approximately  16,743  square feet of
space at 1238 Anthony Road, Burlington,  North Carolina. Since 1986, the Company
has expanded the space rented  under the lease to  approximately  22,272  square
feet. Upon the expiration of the original lease,  the Company entered into a new
lease with Dr.  Powell for the same space and at the same base rental rate for a
term of one year ending on May 31, 1990. Effective June 1, 1990, the Company has
been  leasing the space on a  month-to-month  basis.  The  Company is  currently
leasing space at a rate of approximately  $10,000 per month. The Company intends
to negotiate a new lease with Dr.  Powell in the near future.  The Company holds
certain rights of first refusal to lease  additional space in the building if it
becomes  available  (the building  contains a total of 42,900 square feet).  The
total rent paid by the  Company  to Dr.  Powell  during  the  fiscal  year ended
December 31, 1995 was approximately $121,000.

Lease Agreement with Warren Land Company (WLC)

         The Company leases a farm in Warren County, North Carolina from WLC for
the purposes of maintaining  animals to produce  antibodies and for research and
development.  Dr. Powell owns a 12% interest in WLC, and the remainder of WLC is
owned by certain of Dr. Powell's family members and their  respective  families.
The  arrangement  for use of the Warren County  facility is on a  month-to-month
basis at a rental of $2,797 per month.  The Company  intends to  negotiate a new
lease with WLC in the near  future.  The total  rent paid by the  Company to WLC
during the fiscal year ended December 31, 1995 was approximately $34,000.

Loan to Mr. James D. Skinner

         The provisions of  non-qualified  stock options  granted to Mr. Skinner
provide  that the Company will lend the funds  necessary to exercise  such stock
options. The loans for this purpose will not exceed a term of 36 months and will
bear interest at a rate equal to the prime lending rate of Wachovia Bank & Trust
Company,  N.A. and will be secured by a pledge of the shares  purchased with the
proceeds of the loan.  During 1988, Mr. Skinner  exercised  non-qualified  stock
options  exercisable  into 13,334 shares of Common Stock at an exercise price of
$7.50 per share. At Mr.  Skinner's  request,  the Company loaned $100,000 to Mr.
Skinner to be used to exercise  such options.  The loan was secured  solely by a
pledge of, and as  recourse  only with  respect  to, the shares of Common  Stock
purchased  with the  proceeds of the loan.  Effective  May 3, 1990,  the Company
modified the loan agreement with Mr. Skinner to defer interest  payments on such
loan until the date upon which the  principal  comes due.  In 1995,  the Company
modified the loan  agreement with Mr. Skinner to extend the maturity date of the
loan to September 28, 1996. The outstanding  balance of such loan as of December
31, 1995, was $100,000, excluding accrued interest thereon.

Loan From Dr. Samuel C. Powell

<PAGE>

On December 18, 1995, the Company borrowed $100,000 from Dr. Samuel C. Powell in
the form of a 90 day loan.  The loan had an interest rate of 10.5%.  The Company
repaid the principal and interest in February, 1996.

                         Report of Independent Auditors


The Board of Directors
EDITEK, Inc.


We have audited the accompanying consolidated balance sheets of EDITEK, Inc. as
of December 31, 1995 and 1994, and the related consolidated statements of
operations, stockholders' equity, and cash flows for each of the three years in
the period ended December 31, 1995. Our audits also included the financial
statement schedule listed in the Index at Item 14(a). These consolidated
financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements and schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of EDITEK,
Inc. at December 31, 1995 and 1994, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1995 in
conformity with generally accepted accounting principles. Also, in our opinion,
the related financial statement schedule, when considered in relation to the
consolidated financial statements taken as a whole, presents fairly in
all material respects the information set forth therein.

                   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.

operations from February 12, 1994 to December 31, 1994. As further discussed in

certain sales/administrative functions in the reduced PDLA facility.

The restructuring charge includes a $3,100,000 cost of the write-off of the
goodwill associated with the PDLA acquisition. An additional $731,000 of the
charge is for the write-off of net assets and future minimum lease obligations
at PDLA. A liability of $258,000 related to future minimum lease payments for
the period 1997 through 2000 has been classified as noncurrent.

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.

8.    INCOME TAXES (CONTINUED)

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 1993 and through 1994, 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, 1994 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:

                         Report of Independent Auditors

Board of Directors and Stockholders
Medtox Laboratories, Inc.

We have audited the accompanying balance sheet of Medtox  Laboratories,  Inc. as
of December 31, 1995, and the related  statements of  operations,  stockholders'
equity and cash flows for the year then ended.  These  financial  statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these  financial  statements  based on our  audit.  The  financial
statements of Medtox Laboratories,  Inc. for each of the two years in the period
ended  December 31, 1994 were audited by other  auditors  whose  reported  dated
January 31, 1995, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the 1995 financial statements referred to above present fairly,
in all material respects, the financial position of Medtox Laboratories, Inc. as
of December 31, 1995,  and the results of its  operations and its cash flows for
the  year  then  ended,  in  conformity  with  generally   accepted   accounting
principles.

                          Notes to Financial Statements

                                December 31, 1995




1. Business Activity

Medtox  Laboratories,  Inc. (the Company) is a toxicology  reference  laboratory
offering  therapeutic  drug  monitoring,  drugs  of  abuse  screening,  clinical
analyses,  research analyses and emergency toxicology.  The Company is certified
by the Substance  Abuse and Mental Health Services  Administration  (SAMHSA) and
the  College of American  Pathologists  (CAP).  The  Company  operates a medical
laboratory in St. Paul, Minnesota with customers throughout the United States.

2. Summary of Significant Accounting Policies

Cash Equivalents

The Company  considers all highly liquid  investments  with  maturities of three
months or less at the time of purchase to be cash equivalents.

Inventories

Inventories are stated at the lower of cost,  which  approximates  the first-in,
first-out basis, or market.

Property and Equipment

Property  and  equipment  are stated at cost.  Depreciation  is  provided  using
accelerated and straight-line methods based on estimated useful lives of five to
seven years. Leasehold improvements are amortized over the related lease term or
estimated useful life, whichever is shorter.

Net Revenues

Net revenues  consist of gross billings less  collection site and medical review
officer costs and send-outs, all of which are billed back to the customer.

Income Taxes

The  Company  elected to be taxed as an S  corporation  for income tax  purposes
whereby all items of tax consequences are passed through to the stockholders.

                                                                              7

                    Notes to Financial Statements (continued)




2. Summary of Significant Accounting Policies (continued)

The Company  reports its income or loss on the cash basis for tax  purposes.  If
the Company  terminated its S corporation status and changed to a C corporation,
the Company will be required to use the accrual basis for tax purposes resulting
in the  recognition  of  approximately  $2,600,000  of taxable  income  that was
previously deferred.

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.

Reclassifications

Certain  prior  year  amounts  have been  reclassified  to  conform  to the 1995
presentation.

3. Long-Term Debt

Long-term debt consists of the following:

                                   ==========

In 1995,  the Company  entered into a $500,000  revolving  line of credit with a
bank which accrues interest at the prime rate (8.5% at December 31, 1995) and is
secured by a portion of the Company's assets. The Company must repay all amounts
owed under the line of credit by June 30,  1996.  Interest on the line of credit
is payable  monthly.  The Company had no  borrowings  against  this  facility at
December 31, 1995. Certain financing agreements contain various restrictions and
provisions including maintaining certain financial ratios.

Cash paid for interest was  $177,391,  $178,829 and $213,972 for the years ended
December 31, 1995, 1994 and 1993, respectively.

4. Commitments

The Company leases office and other  facilities  under certain  operating leases
which expire on various dates through April 2000. Under the terms of the leases,
a pro rata share of  operating  expenses  and real  estate  taxes are charged as
additional  rent.  The Company  subleases one of its facilities to another party
(see Note 8). The amount of sublease  payments  to be  received is $131,217  and
$124,608 for the years ended December 31, 1996 and 1997, respectively.

Future  minimum  lease  commitments  under all  operating  leases  without  
regard to sublease  payments as of December 31, 1995 are as follows:

   1996                                 $   507,248

4. Commitments (continued)

Rent  expense  charged to  operations  was  $464,696,  $463,299 and  $771,796  
for the years ended  December  31, 1995,  1994 and 1993, respectively.

5. Stock Options

The Company  issued stock options to certain key  employees  which allow for the
purchase of an  aggregate of 1,200 shares of Common  Stock.  These  options were
exercised  at $26 per share during 1994.  There were no options  outstanding  at
December 31, 1995 or 1994.

6. Benefit Plan

The  Company  has a defined  contribution  profit  sharing  Plan,  with a 401(k)
provision,  that covers  substantially  all  employees  who meet certain age and
length of service requirements.  Contributions to the plan are at the discretion
of the Board of Directors.  The 401(k)  expense for the years ended December 31,
1995, 1994 and 1993 was $78,038 $68,857 and $70,700, respectively.

7. Related Party Transactions

The  Company  provided  laboratory  services  to  an  entity  owned  by  certain
stockholders  and  employees of the Company  through  December  31, 1994.  These
laboratory  services were bundled with other  services which the Company did not
offer, and sold as a package to certain  clients.  Total sales to the entity for
1994 and 1993 were $372,741 and $431,955, respectively.

The Company  also  purchased  services,  including  collection  site and medical
review officer services,  and customized  specimen collection supplies from that
same entity through December 31, 1994. Purchases for 1994 and 1993 were $231,604
and $1,169,731, respectively.

                                                                           10

8. Restructuring Accrual

Effective October 31, 1993, the Company sold substantially all of its California
operations to a third party for $300,000. In addition, the buyer assumed certain
liabilities  of the  operation  and entered  into an  assignment  of the related
lease. The sale of the assets resulted in a loss of approximately $457,000 which
was reflected in restructuring costs for the year ended December 31, 1993.

The Company  closed its Illinois  division on December 31, 1993.  In  connection
with this closing,  the Company recorded  restructuring  expenses as of December
31, 1993 of approximately  $705,000.  The expenses  included lease  obligations,
severance and vacation costs and other  miscellaneous  expenses directly related
to the closing of the facility.  During 1994,  the Company was not successful in
subleasing  the  Illinois  facility as a  laboratory.  Accordingly,  the Company
revised the estimate of sublease  payments based on reconfiguring  the space for
general office use at a lower lease rate and expensed an additional $567,700 for
the  year  ended  December  31,  1994.  At  December  31,  1995  and  1994,  the
restructuring  accrual of $730,907 and $917,865,  respectively,  represents  the
present value of future lease obligations through the lease term of April 2000.

9. Subsequent Event

On January  30,  1996,  the  Company  sold  substantially  all of its assets and
liabilities other than cash and cash equivalents to a publicly-held company (the
Purchaser) for $24 million,  consisting of $19 million in cash and $5 million in
the form of 2,517,306 shares of common stock of the Purchaser.

                                                                              11

                  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 A                       2.0% above Prime Rate
          Term Loan B                       2.5% above Prime Rate
          Credit Facility                   1.5% above Prime Rate

   c) Goodwill representing the excess of the purchase price of $24 million over
     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

     value of the assets is a  preliminary  allocation  absent an  appraisal  of

     distribution  expenses to conform with the historical  presentation  of the
     financial statements of EDITEK. These  reclassifications  have no impact on
     the operating income of MEDTOX.

h)   Adjustment to reflect  acquisition costs which are expected to approximate
     $400,000,  certain severance payments of $370,000, less the accrued payroll
     of MEDTOX of $139,000, which was not purchased by the Company.

i)   Adjustment to reflect the restructuring charge of $3,800,000 which consists
     of the  write-off of the remaining  goodwill of $3,100,000  and $700,000 of
     certain  other   restructuring   costs.  (The  Company  believes  that  the
     restructuring  charge  should be  reflected  in the pro forma  statement of
     operations  as  the  restructuring  was  a  direct  result  of  the  MEDTOX
     acquisition.)

                              EMPLOYMENT AGREEMENT


         THIS AGREEMENT, effective as specified herein, between Medtox
Laboratories, Inc., a Minnesota corporation ("Medtox") (substantially all of the
assets of Medtox are to be acquired by Psychiatric Diagnostic Laboratories of
America, Inc. ("PDLA"), a wholly-owned subsidiary of Editek, Inc. ("Editek"),
pursuant to which transaction this Agreement shall be assumed) and Harry G.
McCoy ("Employee").

         NOW, THEREFORE, in consideration of the terms and mutual undertakings
herein contained, it is agreed by and between Medtox and Employee as follows:

         1. Effective Date and Term of Employment: This Agreement shall become
effective on January 30, 1996, the date of the asset acquisition transaction
between Medtox and Editek (the "Acquisition"), and shall supersede the Change in
Control Agreement between Employee and Medtox effective as of December 30, 1994.
The Agreement shall remain in effect until the close of business two years from
such effective date (the "Agreement Expiration Date"); provided, however, that
on the Agreement Expiration Date and on each anniversary of the Agreement
Expiration Date (a "Renewal Date"), this Agreement shall be renewed for a period
of one additional consecutive year unless either Medtox or Employee provides
written notice to the other party at least ninety (90) days prior to a Renewal
Date that the Agreement shall terminate without renewal as of the corresponding
Agreement Expiration Date. When the Agreement extends for a period of one
additional consecutive year, the Agreement Expiration Date shall also extend by
one year.

         2. Duties and Responsibilities: Employee is the President of Laboratory
Operations of Medtox and, following the Acquisition, Employee shall have a
comparable position, subject to such changes in level of responsibility,
position, authority or duty as are consistent with the Acquisition (without
prejudice to seek a Severance Award pursuant to Sectoin 5.2). Employee hereby
agrees to faithfully and competently render services on a full-time basis to
Medtox in the foregoing capacity and to devote his best efforts, skill and
attention (except during vacations and leaves conforming with Medtox policies)
to Medtox.

          3. Compensation: Medtox agrees to employ Employee for the term and in
the capacities described in Sections 1 and 2 above and to compensate Employee
for such services as follows:

                  3.1 Employee shall be paid a base salary of one hundred
sixty-seven thousand dollars ($167,000) per annum ("Base Salary"). Employee
shall be eligible for annual increases in such Base Salary; and the first such
increase, if any, shall become effective on or before the first anniversary of
the most recent change in Base Salary. Said Base Salary, including any
increases, shall be paid in equal installments in accordance with

                                                                 Page 1 of 14

<PAGE>



Medtox's customary pay schedule and shall be subject to applicable withholding
for federal and state income taxes and social security and related deductions.

                  3.2 Benefit Plans: During the term of this Agreement, Employee
shall be entitled to participate in the benefit plans or bonus programs
established by Medtox for its senior management as in effect from time to time.
Nothing in this Section 3.2 shall be construed as limiting the ability of Medtox
to amend or terminate any of its benefit plans or bonus programs, or to afford
Employee greater rights than exist pursuant to the terms and provisions of the
benefit plans or bonus programs.

         4. Expense Reimbursement: Medtox shall pay or reimburse Employee for
all ordinary and necessary expenses reasonably incurred in the performance of
his duties hereunder. Such reimbursement shall be made against the submission by
Employee of properly signed and supported itemized expense reports in accordance
with the travel and business reimbursement policies of Medtox in effect from
time-to-time.

         5.       Termination of Employment:

                  5.1 Employee Resignation: Employee may terminate his
employment prior to the termination of this Agreement by submitting a written
notice of resignation to the Chief Executive Officer of Editek (the "C.E.O."),
specifying a termination date which shall be no sooner than ninety (90) days
after the submission of said notice, unless Employee and C.E.O. shall agree to a
shorter notice period. During this ninety (90) day period, Employee shall
receive current Base Salary installments and benefits in accordance with
Medtox's customary pay schedule and policies, but his duties and the capacity in
which he serves shall be subject to such conditions and limitations as may be
imposed by the C.E.O. If Employee and C.E.O. agreement to a shorter notice
period, payments to Employee shall continue only for the notice period. The
termination of Employee's employment that does not result in the payment of a
Severance Award as defined in Section 5.2 shall not result in any further
payments hereunder except as provided in this Section 5.1; and a voluntary
termination that does not satisfy the provisions of Section 5.2(b) shall not
result in the payment of a Severance Award.

                  5.2 Termination Without Cause and Eligibility for Severance
Award: The severance payments described in Section 6 (the "Severance Award")
shall be payable to Employee if Employee's employment with Medtox terminates
during the term of this Agreement and within twelve (12) months following a
Change in Control for any of the following reasons:

                           (a)      involuntarily, other than an involuntary
                                    termination on account of Misconduct; or

                           (b)      voluntarily, following:


                                                                    Page 2 of 14

<PAGE>



                                            (i) any reduction in Employee's Base
                                    Salary from the level existing at any time
                                    within ninety (90) days preceding the date
                                    of a Change in Control;

                                            (ii) any material reduction in the
                                    health care or retirement benefits provided
                                    to Employee. It is the intent that this
                                    provision will in no way limit the ability
                                    of Editek to reasonably alter, which would
                                    include a reasonable reduction, health care
                                    and retirement benefits on account of a
                                    Change in Control without triggering the
                                    payment of a Severance Award, provided that
                                    any such alteration is uniformly applied to
                                    all similarly situated employees;

                                            (iii) any relocation to which
                                    Employee has not agreed to an office of
                                    Medtox or if a related entity more than
                                    thirty (30) miles from the office where
                                    Employee was located at the time of the
                                    Change in Control or any increase in
                                    Employee's required travel amounting to a
                                    constructive relocation; or

                                            (iv) any material reduction in the
                                    level of responsibility, position (including
                                    status, office, title, reporting
                                    relationships or working conditions),
                                    authority or duties of Employee with Medtox
                                    from that as existed within ninety (90) days
                                    preceding the date of a Change in Control.
                                    The intent of this provision is that
                                    Employee, following a Change in Control,
                                    will have a materially comparable position
                                    with Medtox or a successor or related entity
                                    as existed within ninety (90) days preceding
                                    the date of a Change in Control and that
                                    changes in level of responsibility,
                                    position, authority or duties which are
                                    consistent with the Change in Control will
                                    not be construed as constituting a material
                                    reduction. If Employee believes that a
                                    material change has occurred, Employee shall
                                    provide Medtox with notice and a reasonable
                                    opportunity to cure (not to exceed fifteen
                                    (15) business days); or

                           (c)      voluntarily if, following a Change in
                                    Control, Medtox or any successor of Medtox
                                    either announces that it will not honor or
                                    cause Medtox to honor the terms of this
                                    Agreement, or if Medtox or any successor of
                                    Medtox or related entity at any time fails
                                    to confirm in writing to Employee, within
                                    fifteen (15) business days of a request by
                                    Employee, that it will honor and will cause
                                    Medtox to honor the terms of this Agreement.



                                                                    Page 3 of 14

                  5.3. The date of Employee's cessation of active employment
shall constitute Employee's "Termination Date." Although the Acquisition between
Medtox and Editek shall not constitute a termination of employment for purposes
of this Agreement, it is the intent of this Agreement that such transaction will
constitute a Change in Control such that a termination of Employee's employment
which satisfies the requirements of Section 5.2 above, will result in the
payment of a Severance Award.

                  6. Severance Award: The Severance Award, which shall be in
lieu of additional payments under this Agreement, shall consist of the
following:

                  6.1 If terminated during the initial two (2) year period of
this Agreement, a lump sum equal to the sum of: (i) twenty-four (24) months'
Base Salary; and (ii) two (2) times the most recent annual bonus paid or payable
to employee or, if greater, the annual bonus paid or payable to Employee for the
fall fiscal year ended prior to the fiscal year during which the Change in
Control occurred, payable as soon as administratively possible after Employee's
Termination Date but in no event later than thirty (30) days after the
Employee's Termination Date; and, if terminated during a one year renewal
period, a lump sum equal to twelve (12) months' Base Salary, payable as soon as
administratively possible after Employee's Termination Date but in no event
later than thirty (30) days after the Employee's Termination Date. Nothing
herein shall be construed to result in the nonpayment of Employee's accrued
compensation as of his Termination Date. For purposes hereof, accrued
compensation shall include amounts earned but not paid, including any accrued
vacation pay.

                  6.2 Advance payment or subsequent reimbursement of reasonable
expenses in an amount up to ten thousand dollars ($10,000), incurred by Employee
in the pursuit of subsequent employment during the period of six (6) months
following Employee's Termination Date, including reasonable expenses for any
reputable outplacement assistance or such other administrative assistance as may
be necessary to secure subsequent employment, for tax or accounting assistance
on account of termination of employment, and for phone and mail services, and
for reasonable travel expenses.

                  6.3 A lump sum payment of an amount equal to the cost of
employee-only coverage for a period of eighteen (18) months under the group
health plan maintained by or on behalf of Medtox. Such lump sum shall be paid as
soon as administratively possible after Employee's Termination Date, but in no
event later than thirty (30) days after the Employee's Termination Date. The
payment under this subsection is in no way intended to reduce or limit any
continuation coverage under such group health plan to which Employee and any of
his or her qualified beneficiaries are entitled under the provisions of the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended; and such
payment shall be made regardless of whether Employee is participating in the
group health plan or elects continuation coverage under such plan.


                                                                    Page 4 of 14

<PAGE>



                  6.4 To the extent an equity award held by Employee is not
fully vested and exercisable on Employee's Termination Date on account of the
relevant Change in Control, Employee shall be entitled to a lump sum payment in
an amount equal to the value lost under the equity award, payable as soon as
administratively possible after the date that the equity award is forfeited in
whole or in part, and in no event payable later than thirty (30) days after the
Employee's Termination Date. The value lost by Employee under an equity award
shall be determined by calculating the net benefit lost by Employee, exclusive
of taxes, assuming that Employee was fully vested in his equity award on his
Termination Date, exercised the equity award and, if necessary, sold the
underlying stock at the time the equity award is otherwise forfeited. By way of
example, if Employee would have otherwise forfeited an incentive stock option on
his Termination Date, and the option terms required a two dollar ($2.00)
exercise price per share and the fair market value of the stock was five dollars
($5.00) per share on his Termination Date, Employee would be entitled to a
payment of three dollars ($3.00) per share.

                  6.5 A lump sum payment equivalent on an after-tax basis to the
additional amount Employee would have had in his 401(k) plan account had he: (i)
continued as an employee of Medtox for an additional twelve (12) months and
continued to receive his Base Salary as in effect on his Termination Date and
received an allocation of employer contributions, including deferrals, based on
the maximum percentage allocated to his account for the last two (2) immediately
preceding plan years; and (ii) retired at his early retirement date. The lump
sum payment will be calculated assuming that the 401(k) account had grown at the
rate of average plan earnings for the most recent two (2) plan years preceding
the Change in Control. The lump sum shall be paid not later than thirty (30)
days after the Employee's Termination Date.

         7. Responsibilities of Employee: In consideration of the Severance
Award set forth in Section 6 above, Employee agrees to execute a general release
acceptable to Medtox and Editek, which release shall include a release with
respect to any beneficiary of Employee entitled to or eligible to receive all or
a portion of any Severance Award hereunder. Notwithstanding any provision set
forth in this Agreement, if Employee shall not execute such a general release,
then Employee's Severance Award shall consist solely of two (2) months' Base
Salary, payable in a lump sum as soon as administratively possible following
Employee's Termination Date but not later than thirty (30) days after the
Termination Date.

         8.       Limitations of Agreement:

                  8.1 Employee shall not be entitled, solely by reason of a
Severance Award or any other provision of this Agreement, to continue to
participate in any employee benefit plans or fringe benefit programs maintained
by Medtox or for the benefit of Medtox employees, and the rights of Employee to
continue to participate in such plans and programs shall be governed solely by
their terms and applicable law.


                                                                    Page 5 of 14

<PAGE>



                  8.2 Nothing in this Agreement, including a Severance Award,
shall in any way be construed to extend the period of Employee's employment with
Medtox, and Employee's Termination Date shall not be extended beyond the last
official work day for which Employee is paid for active service.

                  8.3 Employee shall be entitled to a cash payment of an amount
equal to the amount of any excise tax liability incurred by Employee pursuant to
Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), in
connection with the payment of the Severance Award, plus an additional amount
intended to compensate Employee for the federal and state income tax liability
in connection with such cash payment. The amount of the total cash payment
payable under this Section 8.3 shall be determined pursuant to the following
formula:

                        X       = the sum of the maximum federal
                                individual income tax rate and the
                                maximum individual income tax rate
                                for the Employee's State of primary
                                residence for the year in which the
                                stock award become taxable to
                                Employee (e.g., .40)

                        amount           amount of excise tax liability
                        of cash  =
                        payment                         1 - X

         9. Termination on Account of Death: Notwithstanding any provision
herein to the contrary, upon the death of Employee prior to the payment of or
entitlement to a Severance Award, the Base Salary which would have been payable
under Section 3.1 of this Agreement during the remainder of the term of the
Agreement (without any renewal hereunder), but in no event less than twelve (12)
months of Base Salary, shall be paid in a lump sum within thirty (30) days of
Employee's death to the beneficiary designated by Employee for such purpose (if
no designation has been made, payment will be to the estate of Employee). Upon
the death of Employee after Severance Award payments are initiated or after he
becomes entitled to the payment of a Severance Award, the balance of the
Severance Award shall be paid to the beneficiary designated by Employee for such
purpose or, if no designation has been made, payment will be made to the estate
of Employee. If an insurance arrangement has been implemented and accepted in
writing by Employee for the purpose of satisfying Medtox's obligation under this
Agreement under which benefits are payable upon Employee's death, the lump-sum
payment specified above shall not be provided, or shall be reduced on a dollar
equivalent basis for payments received by Employee's beneficiary or estate from
such insurance arrangement on account of Employee's death.

                  10. Termination for Disability: Notwithstanding any provision
herein to the contrary, upon the termination of employment on account of
disability prior to the payment or entitlement of a Severance Award, Employee
shall continue to receive the Base Salary that would otherwise have been payable
under Section 3.1 of the Agreement during the remainder

                                                                    Page 6 of 14

of the term of the Agreement (without any renewal hereunder) but in no event
will the payments received on account of termination on account of a disability
be less than twelve (12) months of Base Salary. Employee may elect to delay the
payment of disability benefits on terms mutually agreeable with Medtox if the
payment thereof shall result in the reduction of any insured disability benefit
to which Employee is entitled. For purposes of this Agreement, disability shall
be defined as disability that would entitle Employee to disability payments
under any long term disability plan maintained by Medtox, or alternatively, a
Social Security determination of disability. Whether Employee is terminated for
disability shall in no way be governed by this Section 10, but shall be
determined by the employment policies of Medtox.

         11. Termination for Misconduct: Medtox shall have the right to
terminate Employee's employment under this Agreement for Misconduct. Employee
shall not be entitled to a Severance Award if his employment with Medtox is
terminated for Misconduct; or, for purposes of Section 11(i), if within twelve
(12) months following a termination of employment it is determined that Employee
engaged in Misconduct. For purposes hereof, "Misconduct" shall mean: (i) the
conviction of, or the entering of a plea of, nolo contendere by Employee for any
felony arising out of acts of fraud or dishonesty committed against Medtox or
Editek; or (ii) the intentional and continual failure of Employee to perform his
reasonably assigned duties with Medtox, other than on account of a physical or
mental illness that could reasonably be expected to result in a disability as
defined herein, which failure continues for a period of at least thirty (30)
days after a written notice of demand for substantial performance delivered to
Employee specifying the manner in which Employee has failed substantially to
perform. It will not be grounds for termination for Misconduct if the assigned
duties otherwise result in a violation of Section 5.2(b) of the Agreement,
provided that Employee timely puts Editek on notice of a violation of Section
5.2(b) in accordance with the provisions thereof.

         The determination as to whether Employee's employment has been
terminated for Misconduct shall be made by the C.E.O. Written notice of a
tentative determination of Misconduct, as defined in Section 11(ii) above, shall
be provided to Employee and Employee shall have a reasonable opportunity to cure
such Misconduct. Such written notice shall set forth in reasonable detail the
facts and circumstances that are claimed to constitute Misconduct. If the C.E.O.
shall determine that Employee cannot cure the Misconduct, as defined in Section
11(ii) above, or the cure is not acceptable, or if Employee refuses to cure,
then Employee is subject to immediate termination for Misconduct. If Employee
shall contest the C.E.O.'s determination of Misconduct as defined in Section
11(ii), then the dispute shall be resolved pursuant to Section 20. The C.E.O.'s
determination of termination for Misconduct as defined in Section 11(i) above
shall be final.

                  12. Termination - Records: In the event of the termination or
resignation of Employee pursuant to this Agreement, whether the termination is
voluntary, is without cause or for Misconduct, Employee will transfer all books,
records, documents, and other memoranda of Medtox and any related entity,
including all materials which have come into

                                                                    Page 7 of 14

<PAGE>



his custody, possession and control as a result of employment with Medtox, to
whomsoever Medtox shall designate. Employee shall not, any time after the
resignation or termination of his employment hereunder, divulge to any person
any information or fact relating to the conduct and management of Medtox or any
related entity, which shall have come to his knowledge in the course of his
employment and the disclosure of which would cause damage or loss to Medtox or
any related entity or result in the disclosure of confidential or proprietary
information regarding Medtox or any related entity or any of its members.

         13. Interpretation: This Agreement is being executed and delivered
contemporaneously with the Acquisition. It is the intent of the parties to this
Agreement that immediately following the Acquisition, consistent with the
substance of this Agreement, all references to Medtox shall mean Editek or an
entity related to Editek by which Employee is employed. For example, reference
to benefit plans of Medtox shall mean the benefit plans of Editek or, if
Employee is not employed by Editek, the entity related to Editek by which
Employee is employed.

         14.      Covenant Not to Compete:

                  14.1 Background: This Agreement is being executed and
delivered contemporaneously with and as a condition to the Acquisition by Editek
(the "Purchaser," and for purposes of this Section 14, Purchaser shall also mean
any entity related to Editek, including but not limited to, Medtox) of
substantially all the assets of Medtox ("Seller"). Seller is in the business of
forensic, medical, clinical, biological and/or pharmacological toxicology (the
"Business"). Employee is the President of Laboratory Operations of Seller.
Employee understands that Purchaser will not consummate such Acquisition without
the assurance that Employee will not engage in the activities prohibited by this
covenant not to compete, and in order to induce the Purchaser to consummate the
Acquisition and other transactions contemplated by the Acquisition agreement,
Employee agrees to restrict his actions as provided in this covenant not to
compete. Employee acknowledges and agrees that such restrictions are reasonable
in light of the business of Seller and the direct and substantial benefits of
the Acquisition to Employee and the terms and provisions of this Agreement.

                  14.2 Territory: Employee acknowledges and agrees that Seller
sells its services throughout the United States (the "Territory") and that
Purchaser intends to continue and to increase its sales and operations
throughout the Territory.

                  14.3 Noncompetition Period: The Noncompetition Period
commences on the date of this Agreement and shall terminate on the later of (i)
the second anniversary of the closing date of the Acquisition; or (ii) the first
anniversary of termination of employment with Purchaser; the period for which a
Severance Award is payable hereunder.

                  14.4 Noncompetition: Employee agrees that during the
Noncompetition Period, he will not, directly or indirectly, either:


                                                                    Page 8 of 14

<PAGE>



                           (a)      have any interest in (whether as proprietor,
                                    officer, director or otherwise),

                           (b)      enter the employment of,

                           (c)      act as agent, broker, or distributor for or
                                    adviser or consultant to, or

                           (d)      provide information useful in conducting the
                                    Business to, solicit customers or employees
                                    on behalf of or otherwise provide any
                                    substantial assistance useful in conducting
                                    the Business to any person, firm,
                                    corporation or business entity which is
                                    engaged, or which Employee reasonably knows
                                    is undertaking to become engaged, in the
                                    Territory in the Business or outside the
                                    Territory if sales are solicited from
                                    customers located inside the Territory.

                  Notwithstanding the foregoing, Employee shall not be
prohibited from (i) being employed by or acting as an agent, broker or
distributor for or advisor or consultant to any Non-Business Affiliate of a
person, division, firm, corporation, a business entity ("Parent") which
("Parent"), as one of its businesses, is or may become engaged in the Business
so long as (x) Employee has no relationship or contact with any portion of
Parent which is competitive with the Business, (y) Employee's activities are not
described in clause (d) above and (z) the Business does not constitute more than
ten percent (10%) of the aggregate revenues of Parent on a consolidated basis;
or (ii) owning not more than one percent (1%) of the issued and outstanding
securities of a publicly traded entity which may be engaged in whole or in part
in the Business. A Non-Business Affiliate is a person, division, firm,
corporation or business entity which does not, and is not preparing to, engage
in the Business.

                  14.5     No Interference with Purchaser Customers:  Employee 
agrees that during the Noncompetition Period, he will not, directly or 
indirectly:

                           (a)      solicit, divert or take away, or attempt to
                                    solicit, divert or take away, the business
                                    of any Purchaser Customer; or

                           (b)      attempt or seek to cause any of the
                                    Purchaser Customers to refrain, in any
                                    respect, from maintaining or acquiring from
                                    or through the Purchaser any product or
                                    service of the Business sold (or offered for
                                    sale) to such Purchaser Customer by Seller
                                    or Purchaser during the twelve (12) month
                                    period prior to the date of this Agreement
                                    or during the Noncompetition Period.


                                                                    Page 9 of 14

<PAGE>



                  As used in this Section, "Purchaser Customer" means any
customer of Seller or Purchaser located in the Territory served or solicited by
Seller or Purchaser within the twenty-four (24) month period prior to
termination of employment with Purchaser.

                  14.6 No Interference With Employees: Employee agrees that for
the Noncompetition Period, he will not, directly or indirectly, request or
induce any employee of Purchaser to terminate his employment with Purchaser or
accept employment with another business entity engaged in the Business in the
Territory or which is located outside the Territory if sales are solicited from
customers located inside the Territory.

                  14.7 Notice to Others: Employee hereby agrees that Purchaser
may disclose the provisions of this Section 14 to any person or entity,
including without limitation one that at the time employs or is considering
employing Employee.

                  14.8 Remedies: Employee acknowledges that any violation of
this Section 14 may cause irreparable harm to Purchaser and that damages are not
an adequate remedy. Employee therefore agrees that Purchaser shall be entitled
to injunctive relief, including temporary, preliminary and permanent
injunctions, by an appropriate court in the appropriate jurisdiction, enjoining,
prohibiting and restraining Employee from the continuance of any such violation,
in addition to any monetary damages which might occur by reason of the violation
of this Section 14, including, but not limited to, the forfeiture or repayment
of any Severance Award. The remedies provided in this Section 14.8 are
cumulative and shall not exclude any other remedies to which any party to this
Agreement may be entitled under this Agreement or applicable law, and the
exercise of a remedy shall not be deemed an election excluding any other remedy
(any such claim by the other party to this Agreement being hereby waived).

                  14.9 Modification: It is understood and agreed by the parties
hereto that should any portion, provision or clause of this Section 14 be deemed
too broad to permit enforcement to its full extent, then it shall be enforced to
the maximum extent permitted by law, and Employee hereby consents and agrees
that such scope may be judicially modified accordingly in any proceeding brought
to enforce such restriction.

                  14.10 Independent: The covenants and agreements set forth in
this Section 14 shall be deemed, and shall be construed as, separate and
independent covenants and agreements, and should any part or provision of such
covenants or agreements be held invalid, void or unenforceable by any court of
competent jurisdiction, such invalidity, voidness or unenforceability shall in
no way render invalid, void or unenforceable any other part or provision thereof
or any separate covenant not declared invalid, void or unenforceable; and this
Section 14 shall in that case be construed as if the void, invalid or
unenforceable provisions were omitted.

                                                                   Page 10 of 14

         15.      Miscellaneous:

prepaid) or sent by registered or certified mail, return receipt requested,
postage prepaid, to the address of the party to this Agreement set forth below

express overnight service or on the date of delivery or attempted delivery as

then notice shall thereafter be given pursuant to the foregoing to such
permitted successor or assign.

                  15.2 Assignment; Binding Effect: No assignment, transfer or
delegation of any rights or obligations under this Agreement by a party shall be
made without the prior written consent of the other parties to this Agreement
(which shall not be unreasonably withheld.) This Agreement shall be binding upon
the parties to this Agreement and their respective legal representatives, heirs,
devisees, legatees or other successors and assigns, and shall inure to the
benefit of the parties to this Agreement and their respective permitted legal
representatives, heirs, devisees, legatees or other permitted successors and
assigns.

                  15.3 Gender; Captions: Whenever the context so requires, the
singular number shall include the plural and the plural shall include the
singular, and the gender of any pronoun shall include the other genders. Titles
and captions of or in this Agreement are inserted only as a matter of
convenience and for reference and in no way affect the scope of this Agreement
or the intent of its provisions.

                  15.4 Certain Definitions: The parties agree that "applicable
law" means all provisions of any constitution, statute, law, rule, regulation,
decision, order, decree, judgment, release, license, permit, stipulation or the
official pronouncement enacted, promulgated or issued by any governmental
authority or arbitrator or arbitration panel; that "governmental authority"
means any legislative, executive, judicial, quasi-judicial or other public
authority, agency, department, bureau, division, unit, court or other public
body, person or entity; and that "including" and other words or phrases of
inclusion, if any, shall not be construed as terms of limitation, so that
references to "included" matters shall be regarded as non-exclusive,
non-characterizing illustrations.

                  15.5 Entire Agreement: This Agreement constitutes the entire
agreement of the parties to this Agreement with respect to its subject matter,
supersedes all prior agreements, if any, of the parties to this Agreement with
respect to its subject matter, and may not be amended except in writing signed
by the party to this Agreement against whom the change is being asserted.


                                                                   Page 11 of 14

<PAGE>



                  15.6 No Waiver: The failure of any party to this Agreement at
any time or times to require the performance of any provisions of this Agreement
shall in no manner affect the right to enforce the same; and no waiver by any
party to this Agreement of any provision (or of a breach of any provision) of
this Agreement, whether by conduct or otherwise, in any one or more instances,
shall be deemed or construed either as a further or continuing waiver of any
such provision or breach or as a waiver of any other provision (or of a breach
of any other provision) of this Agreement.

                  15.7 Counterparts: This Agreement may be executed in two or
more copies, each of which shall be deemed an original, and it shall not be
necessary in making proof of this Agreement or its terms to produce or account
for more than one of such copies.

         16. Change in Control: For purposes of this Agreement, "Change in
Control" shall be deemed to have occurred if:

                                    (i) Any "person" as defined in Section
                           3(a)(9) of the Securities Exchange Act of 1934 (the
                           "Act"), including a "group" (as that term is used in
                           Sections 13(d)(3) and 14(d)(2) of the Act), but
                           excluding Editek and any employee benefit plan
                           sponsored or maintained by Editek, including any
                           trustee of such plan acting as trustee, who:

                                            (A) makes a tender or exchange offer
                                    for any shares of Editek's stock pursuant to
                                    which any shares of Editek's stock are
                                    purchased; or

                                            (B) together with its "affiliates"
                                    and "associates" (as those terms are defined
                                    in Rule 12b-2 under the Act) becomes the
                                    "beneficial owner" (within the meaning of
                                    Rule 13d-3 under the Act) of at least fifty
                                    percent (50%) of Editek's stock;

                                    (ii) The shareholders of Editek approve a
                           definitive agreement or plan to merge or consolidate
                           Editek with or into another corporation, to sell or
                           otherwise dispose of all or substantially all of its
                           assets, or to liquidate Editek; or

                                    (iii) When, during any period of twenty-four
                           (24) consecutive months during the existence of the
                           Agreement, the individuals who, at the beginning of
                           such period, constitute the Board (the "Incumbent
                           Directors") cease for any reason other than death to
                           constitute at least a majority thereof; provided,
                           however, that a director who was not a director at
                           the beginning of such twenty-four (24) month period
                           shall be deemed to have satisfied such twenty-four
                           (24) month requirement, and be an Incumbent Director,
                           if such director was elected by, or on the

                                                                   Page 12 of 14

<PAGE>



                           recommendation of or with the approval of, at least
                           two-thirds of the directors who then qualified as
                           Incumbent Directors either actually, because they
                           were directors at the beginning of such twenty-four
                           (24) month period, or by prior operation of this
                           Section.

         17. Indemnification: Medtox agrees to indemnify and hold harmless
Employee for any legal, including reasonable attorneys fees, or court expenses
he may incur while acting within the proper scope of his employment, which right
of indemnification and agreement to hold harmless shall continue in effect
subsequent to any termination herewith so long as any claim or expense relates
to services provided by Employee during his employment. Such indemnification
shall not include any dispute of Employee related to this Agreement.

         18. Binding Effect: This Agreement shall be binding upon the successors
and assigns of Medtox, including those that may result from merger or
reorganization.

         19. Governing Law: This Agreement shall be governed by the laws of the
State of Minnesota without regard to its conflicts of law principles.

         20. Binding Arbitration: Any dispute involving this Agreement, other
than an action by Medtox to enforce its rights pursuant to Section 14 hereof,
shall be resolved through binding arbitration in accordance with the rules of
the American Arbitration Association then in effect. The venue of the
arbitration will be in Minnesota. Any such resolution shall include a
determination as to the portion of the costs of arbitration that shall be borne
by Medtox and by Employee. Except if Employee is terminated for Misconduct, if
Medtox contests the payment of a Severance Award or the calculation of the
Severance Award, after written notice from Employee, Medtox shall make
conditional payments to Employee of a periodic amount equal to what otherwise
would have been his Base Salary until such dispute is resolved. To the extent
Employee shall be entitled to payments in addition to the conditional payments
following a resolution of the dispute, Employee shall be entitled to interest on
such payments. Interest shall be payable from the date beginning thirty (30)
days after Employee's Termination Date and shall be calculated at a rate equal
to one hundred twenty percent (120%) of the applicable Federal rate as of
Employee's Termination Date determined under Section 1274(d) of the Code,
compounded semi-annually. To the extent Employee is required to return all or
any portion of the conditional payments following a resolution of the dispute,
Employee shall be required to include interest on such payments to Medtox.

         21. Severability: In the event any of the provisions of this Agreement
are held to be unenforceable, it is understood that the provision(s) affected
thereby shall not be terminated, but shall be deemed amended to the extent
required to render them valid and enforceable, and the validity and
enforceability of the other provisions of this Agreement shall not be affected
thereby.

         Such action may include, but shall not be limited to, establishing,
         amending or waiving the forms, terms, conditions and duration of an

                  an Award without payment being made in the form of
                  Stock, whether or not Restricted Stock, such shares of
                  Stock or Performance Shares shall not be charged
                  against the aggregate number of shares of Stock
                  available for Awards under the Plan, and may again be
                  available for Award under the Plan.

         (b)      For all purposes under the Plan, each Performance Share

                  Award.

         (c)      To the extent a Stock Right granted in connection with
                  a Stock Option is exercised without payment being made

                  issued upon the exercise of such related Stock Option
                  shall not be charged against the aggregate number of
                  shares of Stock subject to Awards under the Plan, and

         Plan, and any other terms and conditions, not inconsistent with the
         Plan, required by the Committee.

         holders of outstanding shares of Stock, then equitable adjustments
         shall be made by the Committee in:

         (a)      the limitation of the aggregate number of shares of
                  Stock that may be awarded as set forth in Section 3.6
                  of the Plan;

         (b)      the number and class of Stock that may be subject to an
                  Award, and which have not been issued or transferred
                  under an outstanding Award;

         (c)      the purchase price to be paid per share of Stock under
                  outstanding Stock Options and the number of shares of Stock to
                  be transferred in settlement of outstanding Stock Rights; and

         (d)      the terms, conditions or restrictions of any Award and
                  Award Agreement, including the price payable for the
                  acquisition of Stock; provided, however, that all
                  adjustments made as the result of the foregoing in
                  respect of each Incentive Stock Option shall be made so
                  that such Stock Option shall continue to be an
                  Incentive Stock Option, as defined in Section 422 of
                  the Code.

3.12     In addition to such other rights of indemnification as they may have as
         directors or as members of the Committee, the members of the Committee
         shall be indemnified by the Company against reasonable expenses,
         including attorney's fees, actually and necessarily incurred in
         connection with the defense of any action, suit or proceeding, or in
         connection with any appeal therein, to which they or any of them may be
         a party by reason of any action taken or failure to act under or in
         connection with the Plan or any Award granted thereunder, and against
         all amounts paid by them in settlement thereof, provided such
         settlement is approved by independent legal counsel selected by the
         Company, or paid by them in satisfaction of a judgment or settlement in
         any such action, suit or proceeding, except as to matters as to which
         the Committee member has been negligent or engaged in misconduct in the
         performance of his duties; provided, that within 60 days after
         institution of any such action, suit or proceeding, a Committee member
         shall in writing offer the Company the opportunity, at its own expense,
         to handle and defend the same.

3.13     The Committee may require each person purchasing shares of Stock
         pursuant to a Stock Option or other Award under the Plan to represent
         to and agree with the Company in writing that he is acquiring the
         shares of Stock without a view to

                                        9

<PAGE>



         distribution thereof. The certificates for such shares of Stock may
         include any legend which the Committee deems appropriate to reflect any
         restrictions on transfer.

3.14     The Committee shall be authorized to make adjustments in performance
         based criteria or in the terms and conditions of other Awards in
         recognition of unusual or nonrecurring events affecting the Company or
         its financial statements or changes in applicable laws, regulations or
         accounting principles. The Committee may correct any defect, supply any
         omission or reconcile any inconsistency in the Plan or any Award
         Agreement in the manner and to the extent it shall deem desirable to
         carry it into effect. In the event the Company shall assume outstanding
         employee benefit awards or the right or obligation to make future such
         awards in connection with the acquisition of another corporation or
         business entity, the Committee may, in its discretion, make such
         adjustments in the terms of Awards under the Plan as it shall deem
         appropriate.

3.15     The Committee shall have full power and authority to determine whether,
         to what extent and under what circumstances, any Award shall be
         canceled or suspended. In particular, but without limitation, all
         outstanding Awards to any Participant may be canceled if (a) the
         Participant, without the consent of the Committee, while employed by
         the Company or after termination of such employment, becomes associated
         with, employed by, renders services to, or owns any interest in, other
         than any nonsubstantial interest, as determined by the Committee, any
         business that is in competition with the Company or with any business
         in which the Company has a substantial interest as determined by the
         Committee; or (b) is terminated for cause as determined by the
         Committee.


                      ARTICLE IV - INCENTIVE STOCK OPTIONS

4.1      Each provision of this Article IV and of each Incentive Stock Option
         granted hereunder shall be construed in accordance with the provisions
         of Section 422 of the Code, and any provision hereof that cannot be so
         construed shall be disregarded.

4.2      Incentive Stock Options shall be granted only to Eligible Participants
         who are in the active employment of the Company, each of whom may be
         granted one or more such Incentive Stock Options for a reason related
         to his employment at such time or times determined by the Committee
         following the Effective Date until October 26, 2003, subject to the
         following conditions:


                                       10

<PAGE>



         (a)      The Incentive Stock Option price per share of Stock
                  shall be set in the Award Agreement, but shall not be
                  less than 100% of the Fair Market Value of the Stock on
                  the Option Grant Date.  If the Optionee owns more than
                  10% of the outstanding Stock (as determined pursuant to
                  Section 424(d) of the Code) on the Option Grant Date,
                  the Incentive Stock Option price per share shall not be
                  less than 110% of the Fair Market Value of the Stock on
                  the Option Grant Date.

         (b)      The Incentive Stock Option and its related Stock Right,
                  if any, may be exercised in whole or in part from time
                  to time within ten (10) years from the Option Grant
                  Date (five (5) years if the Optionee owns more than 10%
                  of the Stock on the Option Grant Date), or such shorter
                  period as may be specified by the Committee in the
                  Award; provided, that in any event, the Incentive Stock
                  Option and related Stock Right shall lapse and cease to
                  be exercisable upon, or within such period following, a
                  Termination of Employment as shall have been determined
                  by the Committee and as specified in the Incentive
                  Stock Option Award Agreement or its related Stock Right
                  Award Agreement; provided, however, that such period
                  following a Termination of Employment shall not exceed
                  three months unless employment shall have terminated:

                  (i)      as a result of death or Disability, in which
                           event, such period shall not exceed one year after
                           the date of death or Disability; and

                  (ii)     as a result of death, if death shall have occurred
                           following a Termination of Employment and while
                           the Incentive Stock Option or Stock Right was
                           still exercisable, in which event, such period
                           shall not exceed one year after the date of death;
                           provided, further, that such period following a
                           Termination of Employment shall in no event extend
                           the original exercise period of the Incentive
                           Stock Option or any related Stock Right.

         (c)      The aggregate Fair Market Value, determined as of the Option
                  Grant Date, of the shares of Stock with respect to which
                  Incentive Stock Options are first exercisable during any
                  calendar year by any Eligible Participant shall not exceed
                  $100,000; provided, however, to the extent permitted under
                  Section 422 of the Code:

                  (i)      if a Participant's employment is terminated by reason
                           of death, Disability or Retirement and the portion of
                           any Incentive Stock Option that is otherwise
                           exercisable during the post-termination period
                           applied without regard to the $100,000

                                       11

<PAGE>



                           limitation contained in section 422(b)(6) of the Code
                           is greater than the portion of such option that is
                           immediately exercisable as an Incentive Stock Option
                           during such post-termination period under Section
                           422, such excess shall be treated as a Nonqualified
                           Stock Option; and

                  (ii)     if the exercise of an Incentive Stock Option is
                           accelerated by reason of an Acceleration Event, any
                           portion of such Award that is not exercisable as an
                           Incentive Stock Option by reason of the $100,000
                           limitation contained in Section 422(b)(6) of the Code
                           shall be treated as a Nonqualified Stock Option.

         (d)      The Committee may adopt any other terms and conditions which
                  it determines should be imposed for the Incentive Stock Option
                  to qualify under Section 422 of the Code, as well as any other
                  terms and conditions not inconsistent with this Article IV as
                  determined by the Committee.

4.3      The Committee may at any time offer to buy out for a payment in cash,
         Stock, Deferred Stock or Restricted Stock an Incentive Stock Option
         previously granted, based on such terms and conditions as the Committee
         shall establish and communicate to the Participant at the time that
         such offer is made.

4.4      If the Incentive Stock Option Award Agreement so provides, the
         Committee may require that all or part of the shares of Stock to be
         issued upon the exercise of an Incentive Stock Option shall take the
         form of Deferred or Restricted Stock, which shall be valued on the date
         of exercise, as determined by the Committee, on the basis of the Fair
         Market Value of such Deferred Stock or Restricted Stock determined
         without regard to the deferral limitations and/or forfeiture
         restrictions involved.


                     ARTICLE V - NONQUALIFIED STOCK OPTIONS

5.1      One or more Stock Options may be granted as Nonqualified Stock Options
         to Eligible Participants to purchase shares of Stock at such time or
         times determined by the Committee, following the Effective Date,
         subject to the terms and conditions set forth in this Article V.

5.2      The Nonqualified Stock Option price per share of Stock shall be
         established in the Award Agreement and may be less than 100% of the
         Fair Market Value at the time of the grant, or at such later date as
         the Committee shall determine.

                                       12

<PAGE>




5.3      The Nonqualified Stock Option and its related Stock Right, if any, may
         be exercised in full or in part from time to time within such period as
         may be specified by the Committee or in the Award Agreement; provided,
         that, in any event, the Nonqualified Stock Option and the related Stock
         Right shall lapse and cease to be exercisable upon, or within such
         period following, Termination of Employment as shall have been
         determined by the Committee and as specified in the Nonqualified Stock
         Option Award Agreement or Stock Right Award Agreement; provided,
         however, that such period following Termination of Employment shall not
         exceed three months unless employment shall have terminated:

         (a)      as a result of Retirement or Disability, in which event, such
                  period shall not exceed one year after the date of Retirement
                  or Disability, or within such longer period as the Committee
                  may specify; and

         (b)      as a result of death, or if death shall have occurred
                  following a Termination of Employment and while the
                  Nonqualified Stock Option or Stock Right was still
                  exercisable, in which event, such period may exceed one year
                  after the date of death, as provided by the Committee or in
                  the Award Agreement.

5.4      The Nonqualified Stock Option Award Agreement may include any other
         terms and conditions not inconsistent with this Article V or in Article
         VII, as determined by the Committee.


                     ARTICLE VI - STOCK APPRECIATION RIGHTS

6.1      A Stock Appreciation Right may be granted to an Eligible Participant in
         connection with an Incentive Stock Option or a Nonqualified Stock
         Option granted under Article IV or Article V of this Plan, or may be
         granted independent of any related Stock Option.

6.2      A related Stock Appreciation Right shall entitle a holder of a Stock
         Option, within the period specified for the exercise of the Stock
         Option, to surrender the unexercised Stock Option, or a portion
         thereof, and to receive in exchange therefor a payment in cash or
         shares of Stock having an aggregate value equal to the amount by which
         the Fair Market Value of each share of Stock exceeds the Stock Option
         price per share of Stock, times the number of shares of Stock under the
         Stock Option, or portion thereof, which is surrendered.

6.3      Each related Stock Appreciation Right granted hereunder shall be
         subject to the same terms and conditions as the related Stock Option,
         including limitations on

                                       13

<PAGE>



         transferability, and shall be exercisable only to the extent such Stock
         Option is exercisable and shall terminate or lapse and cease to be
         exercisable when the related Stock Option terminates or lapses. The
         grant of Stock Appreciation Rights related to Incentive Stock Options
         must be concurrent with the grant of the Incentive Stock Options. With
         respect to Nonqualified Stock Options, the grant either may be
         concurrent with the grant of the Nonqualified Stock Options, or in
         connection with Nonqualified Stock Options previously granted under
         Article V, which are unexercised and have not terminated or lapsed.

6.4      The Committee shall have sole discretion to determine in each case
         whether the payment with respect to the exercise of a Stock
         Appreciation Right will be in the form of all cash or all Stock, or any
         combination thereof. If payment is to be made in Stock, the number of
         shares of Stock shall be determined based on the Fair Market Value of
         the Stock on the date of exercise. If the Committee elects to make full
         payment in Stock, no fractional shares of Stock shall be issued and
         cash payments shall be made in lieu of fractional shares.

6.5      The Committee shall have sole discretion as to the timing of any
         payment made in cash or Stock, or a combination thereof, upon exercise
         of Stock Appreciation Rights. Payment may be made in a lump sum, in
         annual installments or may be otherwise deferred; and the Committee
         shall have sole discretion to determine whether any deferred payments
         may bear amounts equivalent to interest or cash dividends.

6.6      Upon exercise of a Stock Appreciation Right, the number of shares of
         Stock subject to exercise under any related Stock Option shall
         automatically be reduced by the number of shares of Stock represented
         by the Stock Option or portion thereof which is surrendered.

6.7      Notwithstanding any other provision of the Plan, the exercise of a
         Stock Appreciation Right is required to satisfy the applicable
         requirements under Rule 16b-3 of the Act.

6.8      The Committee, in its sole discretion, may also provide that, in the
         event of a Change in Control and/or a Potential Change in Control, as
         defined in Article XIII, the amount to be paid upon the exercise of a
         Stock Appreciation Right or Limited Stock Appreciation Right shall be
         based on the Change in Control Price, as defined in Section 13.9,
         subject to such terms and conditions as the Committee may specify.

6.9      In its sole discretion, the Committee may grant Limited
         Stock Appreciation Rights under this Article VI.  Limited

                                                        14

<PAGE>



         Stock Appreciation Rights become exercisable only in the event of a
         Change in Control and/or a Potential Change in Control, subject to such
         terms and conditions as the Committee, in its sole discretion, may
         specify. Such Limited Stock Appreciation Rights shall be settled solely
         in cash. A Limited Stock Appreciation Right shall entitle the holder of
         the related Stock Option to surrender such Stock Option, or any portion
         thereof, to the extent unexercised in respect of the number of shares
         of Stock as to which such Limited Stock Appreciation Right is
         exercised, and to receive a cash payment equal to the difference
         between (a) the Stock Appreciation Right Fair Market Value, at the date
         of surrender, of a share of Stock for which the surrendered Stock
         Option or portion thereof is then exercisable, and (b) the price at
         which a Participant could exercise a related Stock Option to purchase
         the share of Stock. Such Stock Option shall, to the extent so
         surrendered, thereupon cease to be exercisable. A Limited Stock
         Appreciation Right shall be subject to such further terms and
         conditions as the Committee shall, in its sole discretion, deem
         appropriate, including any restrictions necessary to comply with
         Section 16(b) of the Act.


            ARTICLE VII - INCIDENTS OF STOCK OPTIONS AND STOCK RIGHTS

7.1      Each Stock Option and Stock Right shall be granted subject to such
         terms and conditions, if any, not inconsistent with this Plan, as shall
         be determined by the Committee, including any provisions as to
         continued employment as consideration for the grant or exercise of such
         Stock Option or Stock Right and any provisions which may be advisable
         to comply with applicable laws, regulations or rulings of any
         governmental authority.

7.2      A Stock Option or Stock Right shall not be transferable by the
         Participant other than by will or by the laws of descent and
         distribution, or, to the extent otherwise allowed by Rule 16b-3 under
         the Act, or other applicable law, pursuant to a qualified domestic
         relations order as defined by the Code or the Employee Retirement
         Income Security Act, or the rules thereunder, and shall be exercisable
         during the lifetime of the Participant only by him or by his guardian
         or legal representative.

7.3      Shares of Stock purchased upon exercise of a Stock Option shall be paid
         for in such amounts, at such times and upon such terms as shall be
         determined by the Committee, subject to limitations set forth in the
         Stock Option Award Agreement. Without limiting the foregoing, the
         Committee may establish payment terms for the exercise of Stock Options
         which permit the Participant to deliver shares of

                                       15

<PAGE>



         Stock, or other evidence of ownership of Stock satisfactory to the
         Company, with a Fair Market Value equal to the Stock Option price as
         payment.

7.4      No cash dividends shall be paid on shares of Stock subject to
         unexercised Stock Options. The Committee may provide, however, that a
         Participant to whom a Stock Option has been granted which is
         exercisable in whole or in part at a future time for shares of Stock
         shall be entitled to receive an amount per share equal in value to the
         cash dividends, if any, paid per share on issued and outstanding Stock,
         as of the dividend record dates occurring during the period between the
         date of the grant and the time each such share of Stock is delivered
         pursuant to exercise of such Stock Option or the related Stock Right.
         Such amounts (herein called "dividend equivalents") may, in the
         discretion of the Committee, be:

         (a)      paid in cash or Stock either from time to time prior to, or at
                  the time of the delivery of, such Stock, or upon expiration of
                  the Stock Option if it shall not have been fully exercised; or

         (b)      converted into contingently credited shares of Stock, with
                  respect to which dividend equivalents may accrue, in such
                  manner, at such value, and deliverable at such time or times,
                  as may be determined by the Committee.

         Such Stock, whether delivered or contingently credited, shall be
         charged against the limitations set forth in Section 3.6.

7.5      The Committee, in its sole discretion, may authorize payment of
         interest equivalents on dividend equivalents which are payable in cash
         at a future time.

7.6      In the event of Disability or death, the Committee, with the consent of
         the Participant or his legal representative, may authorize payment, in
         cash or in Stock, or partly in cash and partly in Stock, as the
         Committee may direct, of an amount equal to the difference at the time
         between the Fair Market Value of the Stock subject to a Stock Option
         and the option price in consideration of the surrender of the Stock
         Option.

7.7      If a Participant is required to pay to the Company an amount with
         respect to income and employment tax withholding obligations in
         connection with exercise of a Nonqualified Stock Option, and/or with
         respect to certain dispositions of Stock acquired upon the exercise of
         an Incentive Stock Option, the Committee, in its discretion and subject
         to such rules as it may adopt, may permit the Participant to satisfy

                                       16

<PAGE>



         the obligation, in whole or in part, by making an irrevocable election
         that a portion of the total Fair Market Value of the shares of Stock
         subject to the Nonqualified Stock Option and/or with respect to certain
         dispositions of Stock acquired upon the exercise of an Incentive Stock
         Option, be paid in the form of cash in lieu of the issuance of Stock
         and that such cash payment be applied to the satisfaction of the
         withholding obligations. The amount to be withheld shall not exceed the
         statutory minimum federal and state income and employment tax liability
         arising from the Stock Option exercise transaction. Notwithstanding any
         other provision of the Plan, any election under this Section 7.7 is
         required to satisfy the applicable requirements under Rule 16b-3 of the
         Act.

7.8      The Committee may permit the voluntary surrender of all or a portion of
         any Stock Option granted under the Plan to be conditioned upon the
         granting to the Participant of a new Stock Option for the same or a
         different number of shares of Stock as the Stock Option surrendered, or
         may require such surrender as a condition precedent to a grant of a new
         Stock Option to such Participant. Subject to the provisions of the
         Plan, such new Stock Option shall be exercisable at the same price,
         during such period and on such other terms and conditions as are
         specified by the Committee at the time the new Stock Option is granted.
         Upon surrender, the Stock Options surrendered shall be canceled and the
         shares of Stock previously subject to them shall be available for the
         grant of other Stock Options.


                         ARTICLE VIII - RESTRICTED STOCK

8.1      Restricted Stock Awards may be made to certain Participants as an
         incentive for the performance of future services that will contribute
         materially to the successful operation of the Company. Awards of
         Restricted Stock may be made either alone, in addition to or in tandem
         with other Awards granted under the Plan and/or cash payments made
         outside of the Plan.

8.2      With respect to Awards of Restricted Stock, the Committee
         shall:

         (a)      determine the purchase price, if any, to be paid for such
                  Restricted Stock, which may be equal to or less than par value
                  and may be zero, subject to such minimum consideration as may
                  be required by applicable law;

         (b)      determine the length of the Restriction Period;


                                       17

<PAGE>



         (c)      determine any restrictions applicable to the Restricted
                  Stock such as service or performance, other than those
                  set forth in this Article VIII;

         (d)      determine if the restrictions shall lapse as to all shares of
                  Restricted Stock at the end of the Restriction Period or as to
                  a portion of the shares of Restricted Stock in installments
                  during the Restriction Period; and

         (e)      determine if dividends and other distributions on the
                  Restricted Stock are to be paid currently to the Participant
                  or paid to the Company for the account of the Participant.

8.3      Awards of Restricted Stock must be accepted within a period of 60 days,
         or such shorter period as the Committee may specify, by executing a
         Restricted Stock Award Agreement and paying whatever price, if any, is
         required. The prospective recipient of a Restricted Stock Award shall
         not have any rights with respect to such Award, unless such recipient
         has executed a Restricted Stock Award Agreement and has delivered a
         fully executed copy thereof to the Committee, and has otherwise
         complied with the applicable terms and conditions of such Award.

8.4      Except when the Committee determines otherwise, or as otherwise
         provided in the Restricted Stock Award Agreement, if a Participant
         terminates employment with the Company for any reason before the
         expiration of the Restriction Period, all shares of Restricted Stock
         still subject to restriction shall be forfeited by the Participant and
         shall be reacquired by the Company.

8.5      Except as otherwise provided in this Article VIII, no shares of
         Restricted Stock received by a Participant shall be sold, exchanged,
         transferred, pledged, hypothecated or otherwise disposed of during the
         Restriction Period.

8.6      To the extent not otherwise provided in a Restricted Stock Award
         Agreement, in cases of death, Disability or Retirement or in cases of
         special circumstances, the Committee, if it finds that a waiver would
         be appropriate, may elect to waive any or all remaining restrictions
         with respect to such Participant's Restricted Stock.

8.7      In the event of hardship or other special circumstances of a
         Participant whose employment with the Company is involuntarily
         terminated, the Committee may waive in whole or in part any or all
         remaining restrictions with respect to any or all of the Participant's
         Restricted Stock, based on

                                       18

<PAGE>



         such factors and criteria as the Committee may deem
         appropriate.

8.8      The certificates representing shares of Restricted Stock may
         either:

         (a)      be held in custody by the Company until the Restriction Period
                  expires or until restrictions thereon otherwise lapse, and the
                  Participant shall deliver to the Company a stock power
                  endorsed in blank relating to the Restricted Stock; and/or

         (b)      be issued to the Participant and registered in the name of the
                  Participant, and shall bear an appropriate restrictive legend
                  and shall be subject to appropriate stop-transfer orders.

8.9      Except as provided in this Article VIII, a Participant receiving a
         Restricted Stock Award shall have, with respect to the shares of
         Restricted Stock covered by any Award, all of the rights of a
         shareholder of the Company, including the right to vote the shares to
         the extent, if any, such shares possess voting rights and the right to
         receive any dividends; provided, however, the Committee may require
         that any dividends on such shares of Restricted Stock shall be
         automatically deferred and reinvested in additional Restricted Stock
         subject to the same restrictions as the underlying Award, or may
         require that dividends and other distributions on Restricted Stock
         shall be paid to the Company for the account of the Participant. The
         Committee shall determine whether interest shall be paid on such
         amounts, the rate of any such interest, and the other terms applicable
         to such amounts.

8.10     If and when the Restriction Period expires without a prior forfeiture
         of the Restricted Stock subject to such Restriction Period,
         unrestricted certificates for such shares shall be delivered to the
         Participant.

8.11     In order to better ensure that Award payments actually reflect the
         performance of the Company and the service of the Participant, the
         Committee may provide, in its sole discretion, for a tandem
         performance-based or other Award designed to guarantee a minimum value,
         payable in cash or Stock to the recipient of a Restricted Stock Award,
         subject to such performance, future service, deferral and other terms
         and conditions as may be specified by the Committee.

                           ARTICLE IX - DEFERRED STOCK

9.1      Shares of Deferred Stock together with cash dividend equivalents, if so
         determined by the Committee, may be issued either alone or in addition
         to other Awards granted under the Plan in the discretion of the
         Committee. The Committee shall determine the individuals to whom, and
         the time or times at which, such Awards will be made, the number of
         shares to be awarded, the price, if any, to be paid by the recipient of
         a Deferred Stock Award, the time or times within which such Awards may
         be subject to forfeiture, and all other conditions of the Awards. The
         Committee may condition Awards of Deferred Stock upon the attainment of
         specified performance goals or such other factors or criteria as the
         Committee may determine.

9.2      Deferred Stock Awards shall be subject to the following
         terms and conditions:

         (a)      Subject to the provisions of this Plan and the
                  applicable Award Agreement, Deferred Stock Awards may
                  not be sold, transferred, pledged, assigned or
                  otherwise encumbered during the period specified by the
                  Committee for purposes of such Award (the "Deferral
                  Period").  At the expiration of the Deferral Period, or
                  the Elective Deferral Period defined in Section 9.3,
                  share certificates shall be delivered to the
                  Participant, or his legal representative, in a number
                  equal to the number of shares of Stock covered by the
                  Deferred Stock Award.

                  Based on service, performance and/or such other factors or
                  criteria as the Committee may determine, the Committee,
                  however, at or after grant, may accelerate the vesting of all
                  or any part of any Deferred Stock Award and/or waive the
                  deferral limitations for all or any part of such Award.

         (b)      Unless otherwise determined by the Committee, amounts
                  equal to any dividends that would have been payable
                  during the Deferral Period with respect to the number
                  of shares of Stock covered by a Deferred Stock Award if
                  such shares of Stock had been outstanding shall be
                  automatically deferred and deemed to be reinvested in
                  additional Deferred Stock, subject to the same deferral
                  limitations as the underlying Award.

         (c)      Except to the extent otherwise provided in this Plan or in the
                  applicable Award Agreement, upon Termination of Employment
                  during the Deferral Period for a given Award, the Deferred
                  Stock covered by such Award shall be forfeited by the
                  Participant; provided, however, the

                                       20

<PAGE>



                  Committee may provide for accelerated vesting in the event of
                  Termination of Employment due to death, Disability or
                  Retirement, or in the event of hardship or other special
                  circumstances as the Committee deems appropriate.

         (d)      The Committee may require that a designated percentage
                  of the total Fair Market Value of the shares of
                  Deferred Stock held by one or more Participants be paid
                  in the form of cash in lieu of the issuance of Stock
                  and that such cash payment be applied to the
                  satisfaction of the federal and state income and
                  employment tax withholding obligations that arise at
                  the time the Deferred Stock becomes free of all
                  restrictions.  The designated percentage shall be equal
                  to the minimum income and employment tax withholding
                  rate in effect at the time under applicable federal and
                  state laws.

         (e)      The Committee may provide one or more Participants subject to
                  the mandatory cash payment with an election to receive an
                  additional percentage of the total value of the Deferred Stock
                  in the form of a cash payment in lieu of the issuance of
                  Deferred Stock. The additional percentage shall not exceed the
                  difference between 50% and the designated percentage cash
                  payment.

         (f)      The Committee may impose such further terms and conditions on
                  partial cash payments with respect to Deferred Stock as it
                  deems appropriate, including any restrictions necessary to
                  comply with Section 16(b) of the Act.

9.3      A Participant may elect to further defer receipt of Deferred Stock for
         a specified period or until a specified event (the "Elective Deferral
         Period"), subject in each case to the Committee's approval and to such
         terms as are determined by the Committee. Subject to any exceptions
         adopted by the Committee, such election must generally be made at least
         12 months prior to completion of the Deferral Period for the Deferred
         Stock Award in question, or for the applicable installment of such an
         Award.

9.4      Each Award shall be confirmed by, and subject to the terms
         of, a Deferred Stock Award Agreement.

9.5      In order to better ensure that the Award actually reflects the
         performance of the Company and the service of the Participant, the
         Committee may provide, in its sole discretion, for a tandem
         performance-based or other Award designed to guarantee a minimum value,
         payable in cash or Stock to the recipient of a Deferred Stock Award,
         subject to

                                       21

<PAGE>



         such performance, future service, deferral and other terms and
         conditions as may be specified by the Committee.


                            ARTICLE X - STOCK AWARDS

10.1     A Stock Award shall be granted only in payment of compensation that has
         been earned or as compensation to be earned, including without
         limitation, compensation awarded concurrently with or prior to the
         grant of the Stock Award.

10.2     For the purposes of this Plan, in determining the value of a Stock
         Award, all shares of Stock subject to such Stock Award shall be valued
         at not less than 100% of the Fair Market Value of such shares of Stock
         on the date such Stock Award is granted, regardless of whether or when
         such shares of Stock are issued or transferred to the Participant and
         whether or not such shares of Stock are subject to restrictions which
         affect their value.

10.3     Shares of Stock subject to a Stock Award may be issued or transferred
         to the Participant at the time the Stock Award is granted, or at any
         time subsequent thereto, or in installments from time to time, as the
         Committee shall determine. If any such issuance or transfer shall not
         be made to the Participant at the time the Stock Award is granted, the
         Committee may provide for payment to such Participant, either in cash
         or shares of Stock, from time to time or at the time or times such
         shares of Stock shall be issued or transferred to such Participant, of
         amounts not exceeding the dividends which would have been payable to
         such Participant in respect of such shares of Stock, as adjusted under
         Section 3.11, if such shares of Stock had been issued or transferred to
         such Participant at the time such Stock Award was granted. Any issuance
         payable in shares of Stock under the terms of a Stock Award, at the
         discretion of the Committee, may be paid in cash on each date on which
         delivery of shares of Stock would otherwise have been made, in an
         amount equal to the Fair Market Value on such date of the shares of
         Stock which would otherwise have been delivered.

10.4     A Stock Award shall be subject to such terms and conditions, including
         without limitation, restrictions on the sale or other disposition of
         the Stock Award or of the shares of Stock issued or transferred
         pursuant to such Stock Award, as the Committee shall determine;
         provided, however, that upon the issuance or transfer of shares
         pursuant to a Stock Award, the Participant, with respect to such shares
         of Stock, shall be and become a shareholder of the Company fully
         entitled to receive dividends, to vote to the extent, if any, such
         shares possess voting rights and to exercise

                                       22

<PAGE>



         all other rights of a shareholder except to the extent otherwise
         provided in the Stock Award. Each Stock Award shall be evidenced by a
         written Award Agreement in such form as the Committee shall determine.


                         ARTICLE XI - PERFORMANCE SHARES

11.1     Awards of Performance Shares may be made to certain Participants as an
         incentive for the performance of future services that will contribute
         materially to the successful operation of the Company. Awards of
         Performance Shares may be made either alone, in addition to or in
         tandem with other Awards granted under the Plan and/or cash payments
         made outside of the Plan.

11.2     With respect to Awards of Performance Shares, which may be issued for
         no consideration or such minimum consideration as is required by
         applicable law, the Committee shall:

         (a)      determine and designate from time to time those
                  Participants to whom Awards of Performance Shares are
                  to be made;

         (b)      determine the performance period (the "Performance
                  Period") and/or performance objectives (the
                  "Performance Objectives") applicable to such Awards;

         (c)      determine the form of settlement of a Performance
                  Share; and

         (d)      generally determine the terms and conditions of each such
                  Award. At any date, each Performance Share shall have a value
                  equal to the Fair Market Value, determined as set forth in
                  Section 2.15.

11.3     Performance Periods may overlap, and Participants may participate
         simultaneously with respect to Performance Shares for which different
         Performance Periods are prescribed.

11.4     The Committee shall determine the Performance Objectives of Awards of
         Performance Shares. Performance Objectives may vary from Participant to
         Participant and between Awards and shall be based upon such performance
         criteria or combination of factors as the Committee may deem
         appropriate, including for example, but not limited to, minimum
         earnings per share or return on equity. If during the course of a
         Performance Period there shall occur significant events which the
         Committee expects to have a substantial effect on the applicable
         Performance Objectives during such period, the Committee may revise
         such Performance Objectives.

                                       23

<PAGE>




11.5     The Committee shall determine for each Participant the number of
         Performance Shares which shall be paid to the Participant if the
         applicable Performance Objectives are exceeded or met in whole or in
         part.

11.6     If a Participant terminates service with the Company during a
         Performance Period because of death, Disability, Retirement or under
         other circumstances in which the Committee in its discretion finds that
         a waiver would be appropriate, that Participant, as determined by the
         Committee, may be entitled to a payment of Performance Shares at the
         end of the Performance Period based upon the extent to which the
         Performance Objectives were satisfied at the end of such period and pro
         rated for the portion of the Performance Period during which the
         Participant was employed by the Company; provided, however, the
         Committee may provide for an earlier payment in settlement of such
         Performance Shares in such amount and under such terms and conditions
         as the Committee deems appropriate or desirable. If a Participant
         terminates service with the Company during a Performance Period for any
         other reason, then such Participant shall not be entitled to any
         payment with respect to that Performance Period unless the Committee
         shall otherwise determine.

11.7     Each Award of a Performance Share shall be paid in whole shares of
         Stock, or cash, or a combination of Stock and cash as the Committee
         shall determine, with payment to be made as soon as practicable after
         the end of the relevant Performance Period.

11.8     The Committee shall have the authority to approve requests by
         Participants to defer payment of Performance Shares on terms and
         conditions approved by the Committee and set forth in a written Award
         Agreement between the Participant and the Company entered into in
         advance of the time of receipt or constructive receipt of payment by
         the Participant.


                     ARTICLE XII - OTHER STOCK-BASED AWARDS

12.1     Other awards that are valued in whole or in part by reference to, or
         are otherwise based on, Stock ("Other Stock-Based Awards"), including
         without limitation, convertible preferred stock, convertible
         debentures, exchangeable securities, phantom stock and Stock awards or
         options valued by reference to book value or performance, may be
         granted either alone or in addition to or in tandem with Stock Options,

         Subject to the provisions of the Plan, the Committee shall have
         authority to determine the Eligible Participants to whom and the time
         or times at which such Awards shall be made, the number of shares of
         Stock subject to such Awards, and all other conditions of the Awards.
         The Committee also may provide for the grant of shares of Stock upon
         the completion of a specified Performance Period.

         The provisions of Other Stock-Based Awards need not be the same with
         respect to each recipient.

12.2     Other Stock-Based Awards made pursuant to this Article XII shall be
         subject to the following terms and conditions:

         (a)      Subject to the provisions of this Plan and the Award
                  Agreement, shares of Stock subject to Awards made under this

                  otherwise encumbered prior to the date on which the shares are
                  issued, or, if later, the date on which any applicable
                  restriction, performance or deferral period lapses.

         (b)      Subject to the provisions of this Plan and the Award
                  Agreement and unless otherwise determined by the
                  Committee at the time of the Award, the recipient of an
                  Award under this Article XII shall be entitled to
                  receive, currently or on a deferred basis, interest or
                  dividends or interest or dividend equivalents with
                  respect to the number of shares covered by the Award,
                  as determined at the time of the Award by the
                  Committee, in its sole discretion, and the Committee
                  may provide that such amounts, if any, shall be deemed
                  to have been reinvested in additional Stock or
                  otherwise reinvested.

         (c)      Any Award under this Article XII and any Stock covered by any
                  such Award shall vest or be forfeited to the extent so
                  provided in the Award Agreement, as determined by the
                  Committee, in its sole discretion.

         (d)      Upon the Participant's Retirement, Disability or death, or in
                  cases of special circumstances, the Committee may, in its sole
                  discretion, waive in whole or in part any or all of the
                  remaining limitations imposed hereunder, if any, with respect
                  to any or all of an Award under this Article XII.

         (e)      Each Award under this Article XII shall be confirmed
                  by, and subject to the terms of, an Award Agreement.

         (f)      Stock, including securities convertible into Stock, issued on
                  a bonus basis under this Article XII may be issued for no cash
                  consideration.

12.3     Other Stock-Based Awards may include a phantom stock Award, which is
         subject to the following terms and conditions:

         (a)      The Committee shall select the Eligible Participants who may
                  receive phantom stock Awards. The Eligible Participant shall
                  be awarded a phantom stock unit, which shall be the equivalent
                  to a share of Stock.

         (b)      Under an Award of phantom stock, payment shall be made on the
                  dates or dates as specified by the Committee or as stated in
                  the Award Agreement and phantom stock Awards may be settled in
                  cash, Stock, or some combination thereof.

         (c)      The Committee shall determine such other terms and conditions
                  of each Award as it deems necessary in its sole discretion.


                       ARTICLE XIII - ACCELERATION EVENTS

13.1     For the purposes of the Plan, an Acceleration Event shall occur in the
         event of a "Potential Change in Control," or "Change in Control" or a
         "Board-Approved Change in Control", as those terms are defined below.

13.2     A "Change in Control" shall be deemed to have occurred if:

         (a)      Any "Person" as defined in Section 3(a)(9) of the Act,
                  including a "group" (as that term is used in Sections 13(d)(3)
                  and 14(d)(2) of the Act), but excluding the Company and any
                  employee benefit plan sponsored or maintained by the Company,
                  including any trustee of such plan acting as trustee, who:

                  (i)      makes a tender or exchange offer for any shares of
                           the Company's Stock (as defined below) pursuant to
                           which any shares of the Company's Stock are
                           purchased (an "Offer"); or

                  (ii)     together with its "affiliates" and "associates" (as
                           those terms are defined in Rule 12b-2 under the Act)
                           becomes the "Beneficial Owner" (within the meaning of
                           Rule 13d-3 under the Act) of at least 20% of the
                           Company's Stock (an "Acquisition");


                                       26

<PAGE>



         (b)      The shareholders of the Company approve a definitive agreement
                  or plan to merge or consolidate the Company with or into
                  another corporation, to sell or otherwise dispose of all or
                  substantially all of its assets, or to liquidate the Company
                  (individually, a "Transaction"); or

         (c)      When, during any period of 24 consecutive months during
                  the existence of the Plan, the individuals who, at the
                  beginning of such period, constitute the Board (the
                  "Incumbent Directors") cease for any reason other than
                  death to constitute at least a majority thereof;
                  provided, however, that a director who was not a
                  director at the beginning of such 24 month period shall
                  be deemed to have satisfied such 24 month requirement,
                  and be an Incumbent Director, if such director was
                  elected by, or on the recommendation of or with the
                  approval of, at least two-thirds of the directors who
                  then qualified as Incumbent Directors either actually,
                  because they were directors at the beginning of such 24
                  month period, or by prior operation of this Section
                  13.2(c).

13.3     A "Board-Approved Change in Control" shall be deemed to have occurred
         if the Offer, Acquisition or Transaction, as the case may be, is
         approved by a majority of the Directors serving as members of the Board
         at the time of the Potential Change in Control or Change in Control.

13.4     A "Potential Change in Control" means the happening of any
         one of the following:

         (a)      The approval by shareholders of an agreement by the
                  Company, the consummation of which would result in a
                  Change in Control of the Company, as defined in Section
                  13.2; or

         (b)      The acquisition of Beneficial Ownership, directly or
                  indirectly, by any entity, person or group, other than
                  the Company or any Company employee benefit plan,
                  including any trustee of such plan acting as such
                  trustee, of securities of the Company representing five
                  percent or more of the combined voting power of the
                  Company's outstanding securities and the adoption by
                  the Board of a resolution to the effect that a
                  Potential Change in Control of the Company has occurred
                  for the purposes of this Plan.

13.5     Upon the occurrence of an Acceleration Event, subject to the approval
         of the Committee if the Acceleration Event results from a
         Board-Approved Change in Control, all then outstanding Performance
         Shares with respect to which the

                                       27

<PAGE>



         applicable Performance Period has not been completed shall be paid as
         soon as practicable as follows:

         (a)      all Performance Objectives applicable to the Award of
                  Performance Shares shall be deemed to have been satisfied to
                  the extent necessary to result in payment of 100% of the
                  Performance Shares covered by the Award; and

         (b)      the applicable Performance Period shall be deemed to
                  have ended on the date of the Acceleration Event;

         (c)      the payment to the Participant shall be the amount
                  determined either by the Committee, in its sole
                  discretion, or in the manner stated in the Award
                  Agreement.  This amount shall then be multiplied by a
                  fraction, the numerator of which is the number of full
                  calendar months of the applicable Performance Period
                  that have elapsed prior to the date of the Acceleration
                  Event, and the denominator of which is the total number
                  of months in the original Performance Period; and

         (d)      upon the making of any such payment, the Award Agreement as to
                  which it relates shall be deemed canceled and of no further
                  force and effect.

13.6     Upon the occurrence of an Acceleration Event, subject to the approval
         of the Committee if the Acceleration Event results from a
         Board-Approved Change in Control, the Committee in its discretion may
         declare any or all then outstanding Stock Options, and any or all
         related Stock Rights outstanding for at least six months, not
         previously exercisable and vested as immediately exercisable and fully
         vested, in whole or in part.

13.7     Upon the occurrence of an Acceleration Event, subject to the approval
         of the Committee if the Acceleration Event results from a
         Board-Approved Change in Control, the Committee in its discretion, may
         declare the restrictions applicable to Awards of Restricted Stock,
         Deferred Stock or Other Stock- Based Awards to have lapsed, in which
         case the Company shall remove all restrictive legends and stop-transfer
         orders applicable to the certificates for such shares of Stock, and
         deliver such certificates to the Participants in whose names they are
         registered.

13.8     The value of all outstanding Stock Options, Stock Rights, Restricted
         Stock, Deferred Stock, Performance Shares, Stock Awards and Other
         Stock-Based Awards, in each case to the extent vested, shall, unless
         otherwise determined by the Committee in its sole discretion at or
         after grant but prior to any Change in Control, be cashed out on the
         basis of the

                                       28

<PAGE>



         "Change in Control Price," as defined in Section 13.9 as of the date
         such Change in Control or such Potential Change in Control is
         determined to have occurred or such other date as the Committee may
         determine prior to the Change in Control.

13.9     For purposes of Section 13.8, "Change in Control Price" means the
         highest price per share of Stock paid in any transaction reported on
         the exchange on which the Stock is then traded, or paid or offered in
         any bona fide transaction related to a Potential or actual Change in
         Control of the Company at any time during the 60 day period immediately
         preceding the occurrence of the Change in Control, or, where
         applicable, the occurrence of the Potential Change in Control event, in
         each case as determined by the Committee except that, in the case of
         Incentive Stock Options and Stock Appreciation Rights, or Limited Stock
         Appreciation Rights, relating to such Incentive Stock Options, such
         price shall be based only on transactions reported for the date on
         which the optionee exercises such Stock Appreciation Rights, or Limited
         Stock Appreciation Rights.


                     ARTICLE XIV - AMENDMENT AND TERMINATION

14.1     The Board, upon recommendation of the Committee, or otherwise, at any
         time and from time to time, may amend or terminate the Plan. To the
         extent required by Rule 16b-3 under the Act, no amendment, without
         approval by the Company's shareholders, shall:

         (a)      alter the group of persons eligible to participate in
                  the Plan;

         (b)      except as provided in Section 3.6, increase the maximum number
                  of shares of Stock or Stock Options or Stock Rights which are
                  available for Awards under the Plan;

         (c)      extend the period during which Incentive Stock Option
                  Awards may be granted beyond September 15, 2003;

         (d)      limit or restrict the powers of the Committee with
                  respect to the administration of this Plan;

         (e)      change the definition of an Eligible Participant for the
                  purpose of an Incentive Stock Option or increase the limit or
                  the value of shares of Stock for which an Eligible Participant
                  may be granted an Incentive Stock Option;

         (f)      materially increase the benefits accruing to
                  Participants under this Plan;


                                       29

<PAGE>



         (g)      materially modify the requirements as to eligibility
                  for participation in this Plan; or

         (h)      change any of the provisions of this Article XIV.

14.2     No amendment to or discontinuance of this Plan or any provision thereof
         by the Board or the shareholders of the Company shall, without the
         written consent of the Participant, adversely affect, as shall be
         determined by the Committee, any Award theretofore granted to such
         Participant under this Plan; provided, however, the Committee retains
         the right and power to:

         (a)      annul any Award if the Participant is terminated for
                  cause as determined by the Committee;

         (b)      provide for the forfeiture of shares of Stock or other
                  gain under an Award as determined by the Committee for
                  competing against the Company; and

         (c)      convert any outstanding Incentive Stock Option to a
                  Nonqualified Stock Option.

14.3     If an Acceleration Event has occurred, no amendment or termination
         shall impair the rights of any person with respect to an outstanding
         Award as provided in Article XIII.


                      ARTICLE XV - MISCELLANEOUS PROVISIONS

15.1     Nothing in the Plan or any Award granted hereunder shall confer upon
         any Participant any right to continue in the employ of the Company, or
         to serve as a director thereof, or interfere in any way with the right
         of the Company to terminate his or her employment at any time. Unless
         specifically provided otherwise, no Award granted under the Plan shall
         be deemed salary or compensation for the purpose of computing benefits
         under any employee benefit plan or other arrangement of the Company for
         the benefit of its employees unless the Company shall determine
         otherwise. No Participant shall have any claim to an Award until it is
         actually granted under the Plan. To the extent that any person acquires
         a right to receive payments from the Company under the Plan, such right
         shall, except as otherwise provided by the Committee, be no greater
         than the right of an unsecured general creditor of the Company. All
         payments to be made hereunder shall be paid from the general funds of
         the Company, and no special or separate fund shall be established and
         no segregation of assets shall be made to assure payment of such
         amounts, except as provided in Article VIII with respect to Restricted
         Stock and except as otherwise provided by the Committee.

                                       30

<PAGE>




15.2     The Company may make such provisions and take such steps as it may deem
         necessary or appropriate for the withholding of any taxes which the
         Company is required by any law or regulation of any governmental
         authority, whether federal, state or local, domestic or foreign, to
         withhold in connection with any Stock Option or the exercise thereof,
         any Stock Right or the exercise thereof, or in connection with any
         other type of equity-based compensation provided hereunder or the
         exercise thereof, including, but not limited to, the withholding of
         payment of all or any portion of such Award or another Award under this
         Plan until the Participant reimburses the Company for the amount the
         Company is required to withhold with respect to such taxes, or
         canceling any portion of such Award or another Award under this Plan in
         an amount sufficient to reimburse itself for the amount it is required
         to so withhold, or selling any property contingently credited by the
         Company for the purpose of paying such Award or another Award under
         this Plan, in order to withhold or reimburse itself for the amount it
         is required to so withhold.

15.3     The Plan and the grant of Awards shall be subject to all applicable
         federal and state laws, rules, and regulations and to such approvals by
         any United States government or regulatory agency as may be required.
         Any provision herein relating to compliance with Rule 16b-3 under the
         Act shall not be applicable with respect to participation in the Plan
         by Participants who are not subject to Section 16(b) of the Act.

15.4     The terms of the Plan shall be binding upon the Company, and
         its successors and assigns.

15.5     Neither a Stock Option, Stock Right, nor any other type of equity-based
         compensation provided for hereunder, shall be transferable except as
         provided for herein. Unless otherwise provided by the Committee or in
         an Award Agreement, transfer restrictions shall only apply to Incentive
         Stock Options as required in Article IV and to the extent otherwise
         required by federal or state securities laws. If any Participant makes
         such a transfer in violation hereof, any obligation of the Company
         shall forthwith terminate.

15.6     This Plan and all actions taken hereunder shall be governed by the laws
         of the State of North Carolina, except to the extent preempted by the
         Employee Retirement Income Security Act of 1974, as amended.

15.7     The Plan is intended to constitute an "unfunded" plan for
         incentive and deferred compensation.  With respect to any
         payments not yet made to a Participant by the Company,

                                       31

<PAGE>


         nothing contained herein shall give any such Participant any rights
         that are greater than those of a general creditor of the Company. In
         its sole discretion, the Committee may authorize the creation of trusts
         or other arrangements to meet the obligations created under the Plan to
         deliver shares of Stock or payments in lieu of or with respect to
         Awards hereunder; provided, however, that, unless the Committee
         otherwise determines with the consent of the affected Participant, the
         existence of such trusts or other arrangements is consistent with the
         "unfunded" status of the Plan.

15.8     Each Participant exercising an Award hereunder agrees to give the
         Committee prompt written notice of any election made by such
         Participant under Section 83(b) of the Code, or any similar provision
         thereof.

15.9     If any provision of this Plan or an Award Agreement is or becomes or is
         deemed invalid, illegal or unenforceable in any jurisdiction, or would
         disqualify the Plan or any Award Agreement under any law deemed
         applicable by the Committee, such provision shall be construed or
         deemed amended to conform to applicable laws or if it cannot be
         construed or deemed amended without, in the determination of the
         Committee, materially altering the intent of the Plan or the Award
         Agreement, it shall be stricken and the remainder of the Plan or the
         Award Agreement shall remain in full force and effect.

                               EDITEK, INC.

                            ASSET PURCHASE AGREEMENT

         AGREEMENT, dated as of May __, 1995 (the "Agreement"), between and
among EDITEK, Inc., a Delaware corporation ("Purchaser"), Bioman Products Inc.,
an Ontario corporation ("Subsidiary"), and NOVAMANN International Inc., a
Canadian corporation ("Parent").

         WHEREAS, Parent and Subsidiary desire to sell to Purchaser all the
assets of Subsidiary and certain assets of Parent, and Purchaser desires to
purchase such assets, pursuant to the terms and conditions set forth in this
Agreement.

         NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound hereby, agree as follows:

                                    ARTICLE I
                                   ASSET SALE

         Section 1.1 Subsidiary Asset Sale. Subsidiary agrees to sell, and
Purchaser agrees to purchase, all the tangible and intangible assets of
Subsidiary, including, without limitation, all inventory (including without
limitation all antibody, conjugate and hapten), cash and cash equivalents,
equipment, contracts, leases, subleases, licenses (subject to Section 1.9
hereof), customer and supplier lists, tradenames and marks, but excluding any
contracts or other assets rejected by Purchaser. Schedule 1.1 hereto contains a
list of all Assets of Subsidiary on March 31, 1995. Until the Closing Date
Subsidiary will not transfer any assets, except sales of inventory and cash
payments for payroll purposes, both of which shall be in the ordinary course of
business consistent with prior practices as explained to Purchaser. All assets
to be sold by Subsidiary hereunder, whether or not listed on Schedule 1.1
hereto, are hereinafter referred to as "Subsidiary Assets."

         Section 1.2 Parent Asset Sale. Parent hereby agrees to cause its
Affiliates to sell, and Purchaser hereby agrees to purchase, the items listed on
Schedule 1.2 hereto (hereinafter referred to as the "Parent Assets").

         Section 1.3 Other Assets. For a period of three years after the Closing
Parent will continue to provide Purchaser at rates listed on Schedule 1.3 hereto
use of the equipment and services which are listed on Schedule 1.3 hereto.
Subsidiary (or Parent in the name of Subsidiary) has applied for an investment
tax credit from the government of Canada, which tax credit may not be paid until
after Closing. Fifty (50%) Percent of any tax credit received by Parent or
Subsidiary in respect of research activities conducted by or on behalf of
Subsidiary shall be paid to Purchaser promptly upon receipt by Parent or
Subsidiary.



<PAGE>



         Section 1.4 Transfer of Title. Seller and Parent shall enter into such
agreements, sign such consents, and take any other actions as may be reasonably
necessary to convey title to the Subsidiary Assets and Parent Assets to
Purchaser, free and clear of all liens and encumbrances, except those
specifically assumed by Purchaser.

         Section 1.5 Employees. Parent and Subsidiary shall take all actions
reasonably requested by Purchaser to assist Purchaser to convince personnel
selected by Purchaser to become employed by Purchaser. It is contemplated that
Purchaser shall hire the current employees of Subsidiary. However, Purchaser
shall have no obligation to hire any employees of Subsidiary or Parent. If the
transactions contemplated hereby are not completed, Purchaser agrees not to
solicit the employment of any employee of Parent or Subsidiary for a period of
three years from the dated of this Agreement.

         Section 1.6 Names and Marks. From and after the Closing Date neither
Parent, Subsidiary nor any of their Affiliates shall use the names or marks sold
to Purchaser nor any name or mark similar to any name or mark sold to Purchaser.
Parent and Affiliates other than Subsidiary may continue to use their existing
names as shown on Schedule 1.6 hereto without there being a breach of this
Agreement. Within ten (10) days after the Closing Date, Subsidiary shall have
amended its corporate charter to change its corporate name. All rights to use
names and marks shall be assigned to Purchaser and on the Closing Date or at any
time after the Closing Date Parent and Subsidiary shall execute such documents
as are requested by Purchaser to allow Purchaser to use such names and marks.
Where any name or mark is registered or otherwise protected, Parent and
Subsidiary shall so inform Purchaser and facilitate transfer of such
registration or other protection to Purchaser. Notwithstanding any of the
foregoing, Purchaser shall not use the names or marks of Parent or any Affiliate
except to the extent any such names or marks were owned or used by Subsidiary
prior to the date hereof.

         Section 1.7 Trade Secrets. From and after the Closing Date neither
Parent, Subsidiary nor any of their Affiliates shall use or disclose, whether
orally or in writing, the trade secrets sold to Purchaser. On or prior to the
Closing Date Subsidiary shall deliver a list to Purchaser of all the trade
secrets of Subsidiary, a list of those persons or entities with access to, or
copies of, such trade secrets and the information required to enable Purchaser
to utilize such trade secrets. All copies of such information in whatever form
not delivered to Purchaser shall be destroyed. Parent and Subsidiary shall cause
all others to whom such trade secrets have been disclosed to cease all use
(including all written or oral disclosure) of such trade secrets and to destroy
all copies thereof. From and after the date hereof, Parent, Subsidiary and their
Affiliates (i) shall not disclose such trade secrets to

                                        2

<PAGE>



others, whether orally or in writing, and (ii) shall cooperate with Purchaser to
protect against future use of such trade secrets by others.

         Section 1.8 Good Will. As Purchaser is paying for the good will of
Subsidiary as a going concern, from and after the date hereof neither Parent nor
Subsidiary, nor any of their Affiliates shall take any action that a reasonable
person would have reason to believe may harm the good will and reputation of the
business purchased from Subsidiary by Purchaser.

         Section 1.9 License Rights. The Subsidiary Assets shall include all
rights of Subsidiary, Parent or any of their Affiliates under the License
Agreements between the Minister of Agriculture and Mann Testing Laboratories
with respect to Glycopyrrolate ELISA test kits and Crymoglycate ELISA test kits,
which agreements are listed on Schedule 1.9 hereto (the "License Rights").
Parent, Subsidiary and their Affiliates shall use their best efforts to arrange
for assignment or exclusive sublicense of such License Rights to Purchaser and
approval of such license assignment or sublicense by the Minister of
Agriculture. Failing that, for the duration of the respective License Rights
including any renewals or extensions thereof, Parent, Subsidiary and their
Affiliates shall take all necessary action to ensure that Purchaser has all the
economic benefits of such License Rights, including selling products to
Purchaser at cost (including the royalties payable to Agro-Canada), plus 10%.
Furthermore, Parent, Subsidiary and their Affiliates shall use their best
efforts to assist Purchaser in renewing or extending the License Rights. Any
such license, sublicense or other arrangement shall be without cost to purchaser
as the cost is included in the purchase price for the Assets paid by Purchaser
on the Closing Date.

         Until the later of (i) the sixth anniversary of the Closing Date, (ii)
the date the License Rights, including all renewals, modifications, extensions
and subsequent agreements regarding the same subject matter as the License
Rights, expire and cease to be held by Purchaser or any affiliate of Purchaser,
or any transferee or assignee of Purchaser or (iii) the date the licensor of
such License Rights shall cease negotiating with Purchaser or its affiliates, or
their transferees or assignees with respect to any renewal, modification or
extension of the License Rights or subsequent agreement regarding the same
subject matter as the License Rights, neither Parent or Subsidiary nor any of
their Affiliates shall seek or accept the License Rights or any rights having
the same subject matter as the License Rights, nor shall any of them act as
agent for or otherwise assist any other person or entity seeking such rights
during such period. Parent and its Affiliates shall, however, take any action at
the request of Purchaser to extend the term of the License Rights of Purchaser.
Parent shall not manufacture or sell to any person or entity any Reagents (as
defined below), except as specifically requested by Purchaser.


                                        3

<PAGE>



         "Reagents" means the reagent antibodies, conjugates and haptens and any
other reagent or raw materials provided by Parent to Subsidiary prior to the
date hereof in connection with any product of Subsidiary, specifically
including, without limitation, reagents manufactured pursuant to the License
Rights. Notwithstanding that Subsidiary is selling to Purchaser all its rights
pursuant to the agreement with ImmunoSystems described in Schedule 1.1 hereto
pursuant to Section 1.1, neither Parent nor Subsidiary is disclosing or
otherwise providing to Purchaser in any way any "plate coating" technology,
know-how or tradesecret information obtained by Parent or Subsidiary from the
ImmunoSystems Division of Milipore Corporation, nor shall any such technology,
know-how or tradesecret information be disclosed or provided to Purchaser
pursuant to this Agreement. If Purchaser desires to acquire such technology,
Purchaser must negotiate directly with Milipore Corporation, provided that
Parent shall assist Purchaser in such negotiations.

         Section 1.10 Affiliates. The term Affiliates shall include all persons
and entities that would be "affiliates" under the Securities Exchange Act of
1934. "Affiliates" shall also include all of the current management of Parent
and Subsidiary.

                                   ARTICLE II
                       CONSIDERATION PAYABLE BY PURCHASER

         Section 2.1 Purchase Price. Purchaser shall pay to Parent and
Subsidiary an aggregate purchase price of One Hundred Forty Thousand ($140,000)
Dollars (Canadian) (the "Purchase Price"), which amount shall be allocated
between Parent and Subsidiary at the Closing in the percentages set forth in a
written notice executed by both Parent and Subsidiary and delivered to Purchaser
prior to the Closing. The Purchase Price shall be allocated equitably among
Subsidiary and Parent to reflect the value of assets sold by each.

         Section 2.2  Cash Payment.  40% of the Purchase Price will be
paid by cash, certified check or bank draft at Closing in Canadian
currency.

         Section 2.3 Securities of Purchaser. The remaining 60% of the Purchase
Price will be paid by the issuance of shares of Common Stock of Purchaser (the
"Purchase Shares") having on the date of Closing a market value equal to the
amount of the noncash Purchase Price. No fractional shares shall be issued.
Purchaser shall pay cash in lieu of fractional shares. The market price of the
Common Stock of Purchaser shall be deemed to be the average closing sale price
of a share of Common Stock of Purchaser on the American Stock Exchange during
the ten (10) trading days immediately preceding the Closing Date. Currency
values shall be equal to the average between the sales price of the respective
currencies and the purchase price for the respective currencies as identified in
the Wall Street Journal at the close of business on the last currency trading
date prior to the Closing Date.


                                        4

<PAGE>



         Purchaser shall cause the Purchase Shares to be listed for trading on
the American Stock Exchange at the time of the Closing or as soon as practicable
following the Closing. Notwithstanding such listing Parent and Subsidiary hereby
acknowledge and agree that resale by Parent or Subsidiary of the Purchase Shares
shall be subject to restriction under U. S. securities laws, the Purchase Shares
shall be issued with a restrictive legend and the Purchaser shall impose stock
transfer restrictions with the transfer agent.

         Purchaser hereby agrees to include the Purchase Shares in the first
registration statement (other than a registration statement on Form S-8 or S-4)
filed by Purchaser with the U. S. Securities and Exchange Commission ("SEC")
following the Closing Date, provided SEC rules the allow the Purchase Shares to
be included in such registration statement. In any event, Purchaser shall cause
a registration statement covering the Purchase Shares to become effective not
later than 180 days after the Closing Date. Purchaser shall pay all its costs of
such registration. Parent and Subsidiary hereby agree to provide Purchaser with
such information as Purchaser reasonably requests to facilitate such
registration statement. Upon Parent and Subsidiary becoming able to sell all the
purchase Shares under the rules and regulations of the SEC, Purchaser shall
notify Parent and Subsidiary that the Purchased Shares can be resold under U. S.
securities laws. The date of such written notice is hereinafter referred to as
the "Restriction Termination Date."

         If on the Restriction Termination Date the aggregate market value of
the Purchase Shares is less than the aggregate market value of the Purchase
Shares on the Closing Date (in both cases market value being calculated by the
ten trading date formula set forth above), Purchaser shall issue a number of
additional shares of Common Stock to Parent or Subsidiary equal to the number of
shares required to cause the aggregate market value of shares of Common Stock
held by Parent and Subsidiary to be the same on the Closing Date and the
Restriction Termination Date, provided that the number of additional shares
issued shall not exceed fifty percent (50%) of the number of shares issued on
the Closing Date. In the event that the price of the Purchase Shares on the
Restriction Termination Date shall exceed the price of the Purchase Shares at
Closing by more than One Hundred (100%) Percent, the price in excess of Two
Hundred (200%) Percent of the price at Closing shall be deemed to be payments of
the promissory note of Purchaser provided pursuant to Section 2.4 hereof.

         Section 2.4 Liabilities. Purchaser shall not assume any liabilities of
Subsidiary or Parent, except that Purchaser shall assume (i) the obligation of
Subsidiary to pay to Parent or the Parent's Affiliates, as the case may be,
$40,000 (Canadian) of indebtedness that is currently outstanding (the "Fixed
Intercompany Liabilities"), (ii) up to $80,000 (Canadian) of intercompany
liabilities of Subsidiary to Parent or to Parent's Affiliates, as the case may
be, in existence at the time of the Closing (the "Fluctuating Intercompany
Liabilities") and (iii) trade payables and other usual and customary payables
(the "Trade Payables"),

                                        5

<PAGE>



provided that the Trade Payables assumed by Purchaser shall not exceed the
current assets acquired by Purchaser in this transaction. The Fixed Intercompany
Liabilities and the Fluctuating Intercompany Liabilities are hereinafter
collectively referred to as the "Intercompany Liabilities."

         Parent shall provide Purchaser a list of all Fluctuating Intercompany
Liabilities and all Trade Payables at least two (2) business days prior to the
Closing Date, together with reasonable evidence of the existence and nature of
such liabilities. If the list of Trade Payables exceeds the commitment of
Purchaser as provided above, Purchaser shall select those Trade Payables it will
assume and agrees to pay such assumed Trade Payables as and when they become due

corporation duly organized, validly existing and in good standing under the laws
of Delaware, with all requisite corporate power and authority to own, operate
and lease its properties and to carry on its business as it is now being

in each jurisdiction in which the ownership or leasing of property by it or the
conduct of its business requires

                                        8

<PAGE>



such licensing or qualification, except for such failures to be so qualified or
licensed which would not have a material adverse effect on Purchaser.

         Section 4.2  Authorization; Binding Agreement.  At closing,
Purchaser will have all requisite corporate power and authority to
execute and deliver this Agreement and to perform its obligations
hereunder.  The execution, delivery and performance of this Agree-
ment by Purchaser, and the consummation by Purchaser of the
transactions contemplated hereby, will at closing have been duly
authorized by Purchaser's Board of Directors, and no other
corporate action or proceeding on the part of Purchaser will be
necessary for the execution, delivery and performance of this
Agreement by Purchaser and the consummation of the transactions
contemplated hereby.  This Agreement has been duly and validly
executed and delivered by Purchaser and is a legal, valid and
binding obligation of Purchaser, enforceable against Purchaser in
accordance with its terms except as enforceability may be limited
by bankruptcy, insolvency, reorganization, moratorium and other
similar laws relating to or affecting creditors' rights generally,

to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The financial statements (including any related notes) of
Purchaser included in the SEC Report were prepared in conformity with generally
accepted accounting principles applied on a consistent basis (except as
otherwise stated in such financial statements or, in the case of audited
statements, the related report of Ernst & Young, independent certified public
accountants of Purchaser), and present fairly the consolidated financial
position, results of operations and cash flows of Purchaser as of the dates and
for the periods indicated, subject, in the case of unaudited interim financial
statements to condensation, the absence of certain notes thereto and normal
year-end audit adjustments.

         Section 4.4 Certain Fees. Neither Purchaser, any subsidiary of
Purchaser nor any of their officers, directors, employees or agents has employed
any broker or finder or incurred any liability for any financial advisory,
brokerage or finder's fee or commissions in connection with the transactions

Subsidiary from and against any and all claims, suits, liabilities, costs and
expenses, including reasonable attorneys' fees, resulting

                                        9

claiming a commission, fee or other compensation on the basis of any
communication or agreement such broker may have had or entered into with
Purchaser any of its subsidiaries, officers, directors, shareholders, employees
or agents.

same business conducted by Subsidiary in a manner which is consistent with that
in which it is presently conducted by Subsidiary.

                  (c) Except as set forth in Disclosure Schedule 5.6, neither
the execution and delivery of this Agreement by Parent or Subsidiary, the
performance by Parent and Subsidiary of their obligations hereunder nor the
consummation by Parent and Subsidiary of the transactions contemplated hereby
will (i) conflict with or result in any breach of any provision of the
Certificate of Incorporation or By-laws of Parent or Subsidiary, (ii) result in
a violation or breach of, or constitute (with or without due notice or lapse of
time or the happening or occurrence of any other event) a default by Parent or
Subsidiary, or permit the termination of, or require the consent of any other
party to, or result in the acceleration of, or entitle any party to accelerate

encumbrance upon any properties or assets of Parent or Subsidiary) under, any of

and there is no judgment, decree, injunction, rule or order of any court,
governmental department, commission, agency, instrumentality or arbitrator

or result in any claim, lien or other encumbrance on any of the Parent Assets or
Subsidiary Assets. As of the date hereof, there are no actions, suits or
proceedings pending or, to the knowledge of Parent or Subsidiary, threatened
against Parent or Subsidiary arising out of or in any way related to this

agreements or contracts in effect between Parent or Subsidiary with any of the

Subsidiary or Parent or sale of the assets of Subsidiary or Parent. Except as

wages or salaries of employees of Subsidiary; and neither Parent nor Subsidiary
has any unaccrued liability for any arrears of wages or any taxes or penalties
for failure to comply with any of the foregoing with respect to employees of
Subsidiary. There are no controversies pending, threatened or reasonably
anticipated between Parent or Subsidiary and any employee or former employee of
Subsidiary. None of the employees of Subsidiary are represented by a labor
union, and no petition has been filed or proceeding instituted of which Parent
or Subsidiary has notice by any employee or group of employees with any labor
relations boards seeking recognition of a bargaining representative. There is no
material dispute or controversy with any union or other organization
representing employees, and no arbitration proceeding is pending or threatened
involving such a dispute or controversy.

grounds for assessment of any tax liability or lien against Purchaser or any
Parent Asset or Subsidiary Asset on account of any tax liability of Parent or
Subsidiary.

         Section 5.11 Title to Assets. Parent and Subsidiary have good title to
all the Parent Assets and Subsidiary Assets (other than names and marks) to be
sold to Purchaser hereunder free and clear of any claim, lien or encumbrance of
any third person or entity of any nature whatsoever. The conduct of the business
of Subsidiary as heretofore carried on is free from any infringement of patents,
trademarks, trade names, copyrights or publication rights of others. Parent and
Subsidiary have taken all reasonable measures to protect the trade secrets of
Subsidiary and such trade secrets have not been disclosed to others except
pursuant to reasonable confidentiality agreements. To the best of their
knowledge and belief, Parent and Subsidiary have good title to all the names and
marks included in the Parent Assets and Subsidiary

                                       13

<PAGE>



Assets. None of the Parent Assets or Subsidairy Assets are leased or licensed
from any person or entity, except for any lease or license disclosed on Schedule
1.1 or 1.2 hereof.

         The assets listed on Schedule 1.2 hereto constitute all assets owned by
Parent that are used by Subsidiary on a regular basis to conduct its business,
but which are not regularly used by Parent in its business, whether such use is
pursuant to a lease, license or other agreement or under a less formal
arrangement not constituting a written agreement. Purchaser will assume no
leases, licenses, or other agreements to which any of the Parent Assets or
Subsidiary Assets is subject unless such lease, license or other agreement has
been specifically identified on Schedule 1.1 or 1.2 hereto. Parent, Subsidiary
and their Affiliates have complied with all terms of all of the leases, licenses
and agreements disclosed on Schedule 1.2 up to Closing, and will indemnify and
hold Purchaser harmless against any damages, losses, claims and expenses
(including reasonable attorneys fees and expenses) suffered by Purchaser as a
result of the failure of Parent, Subsidiary or any of their Affiliates to comply
with such terms. Purchaser will indemnify and hold harmless Parent and
Subsidiary for any damages, losses, claims and expenses (including reasonable
attorneys fees and expenses) suffered as a result of Purchaser's failure to
comply with the terms of any of the leases, licenses or agreements disclosed on
Schedule 1.2, provided that Parent, Subsidiary and their Affiliates have
complied with the terms of such lease, license or agreement prior to Closing.

         Section 5.12 Contracts, Minutes and Other Instruments and Information.
Parent and Subsidiary have provided to Purchaser true, correct and complete
copies of all contracts and agreements to which either Parent or Subsidiary is a
party or by which Parent or Subsidiary is bound, in the case of Parent such
representation being limited to contracts affecting the Parent Assets or
Subsidiary Assets. Parent and Subsidiary are in material compliance with all
such contracts and agreements, and to the knowledge of Parent and Subsidiary, no
other party is in breach thereof. Parent and Subsidiary have provided to
Purchaser true, correct and complete copies of all minutes and/or consents of
all actions taken by the shareholders and Board of Directors of Parent and
Subsidiary, in the case of Parent such representation being limited to minutes
and/or consents that affect the Parent Assets or Subsidiary Assets.

         Section 5.13 Permits and Licenses. Subsidiary has acquired and
currently holds all permits, licenses, franchises, authorizations, approvals and
other certificates of authority (the "Licenses") as may be required for
Subsidiary to conduct its business, and copies of all such documents have been
provided to Purchaser. Except as disclosed on Disclosure Schedule 5.13,
Subsidiary is in material compliance with all the terms thereof, the Licenses
are transferable and are being transferred to

                                       14

<PAGE>



Purchaser with the Subsidiary Assets and neither Parent nor Subsidiary is aware
of any reason which any such License could not be renewed on terms at least as
advantageous to Purchaser as the current License held by Subsidiary. Neither
Parent nor Subsidiary is aware of any change in any law, rule or regulation,
whether or not yet effective, which is likely to require Purchaser to obtain in
the future any additional License to conduct the business currently conducted by
Subsidiary.

         Section 5.14 Real Property; Environmental Matters. Subsidiary does not
own any real property and is not a party to any agreement to acquire ownership
of any real property or any interests in real property, and does not occupy or
otherwise use any real property, other than real property subject to lease(s) to
which Subsidiary is a party and are being assigned to Purchaser as part of the
Subsidiary Assets, copies of which have been provided to Purchaser. Except as
disclosed on Disclosure Schedule 5.14, neither Parent nor Subsidiary has (either
with or without negligence) caused or permitted the escape, disposal or release
in violation of applicable law of any biologically active or other hazardous
substances, or materials causing harm in or on any real property occupied or
utilized by Subsidiary in conducting its business (the "Premises"). Neither
Parent nor Subsidiary has allowed the storage or use of such substances or
materials in any manner not sanctioned by law or by commercially reasonable
standards in the industry for the storage and use of such substances or
materials. Neither Parent nor Subsidiary has allowed to be brought onto the
Premises any such materials or substances except to use in the ordinary course
of Subsidiary's business. During the use and occupancy of the Premises by
Subsidiary, Subsidiary has kept and maintained the Premises so as to be in
material compliance with all then existing statutes, laws, rules, ordinances,
orders, permits and regulations of all governmental and regulatory authorities,
agencies and bodies pertaining to environmental matters, or regulating,
prohibiting or otherwise having to do with asbestos and all other toxic,
radioactive or hazardous wastes or materials.

         Section 5.15 Rates for Use of Equipment. The rates listed on Schedule
1.3 hereto for use of equipment and services of Parent are consistent with the
rates historically charged by Parent for use of equipment and services to assist
Subsidiary in the operation of its business.


                                   ARTICLE VI
                     CONDUCT OF BUSINESS PENDING THE CLOSING

hereof and prior to the Closing or earlier termination of this Agreement, unless

the date hereof and (ii) with respect to all plans other than in the ordinary
course of business and consistent with past practice;


                                       16

                  (h) not agree orally or in writing, or otherwise, to take any
of the foregoing actions or any other action which would make any representation
or warranty contained in Article V untrue or incorrect in any material respect
as of the time of the Closing.

                           and NOVAMANN International, Inc.

Gentlemen:

to Purchaser in connection with the  negotiation,  execution and delivery of the
Purchase  Agreement  and  the  consummation  of  the  transactions  contemplated
therein.

         Capitalized  terms used in this  opinion  letter and not  defined in it
have the respective meanings given to those terms in the Purchase Agreement.

         Based  upon  the  foregoing  and  subject  to  the  qualifications  and
limitations set forth herein, we are of the following opinions:

authority to own, operate or lease its properties and to engage

and any other  agreements,  instruments and documents  executed and delivered by
Purchaser  pursuant to the Purchase Agreement  (collectively,  together with the
Purchase Agreement, the "Purchaser Delivered Agreements"):

                           (a)      Purchaser has all requisite corporate power
and authority to execute and deliver the Purchaser Delivered Agreements to which
it is a party and to consummate the transactions  contemplated by, and otherwise
to comply with and perform under, the Purchaser Delivered Agreements;

                           (b)      the execution and delivery by Purchaser of
the  Purchaser  Delivered  Agreements,  the  consummation  by  Purchaser  of the
transactions  contemplated  by them and  Purchaser's  other  compliance  with or

                           (c)      Purchaser has duly and validly executed and
delivered the Purchaser Delivered Agreements.

                  4. The Purchaser Delivered Agreements  constitute legal, valid

their terms, except as enforceability may be limited by bankruptcy,  insolvency,
reorganization,  moratorium  and other  similar  laws  relating to or  affecting
creditors' rights  generally,  by general  equitable  principles  (regardless of
whether such  enforceability  is considered in a proceeding in equity or at law)
or by an implied covenant of good faith and fair dealing.

                  5. The shares of Common Stock (the "Shares") issuable pursuant
to Section 2.3 of the Purchase  Agreement have been duly authorized and reserved
for issuance by all necessary corporate action on the part of the Purchaser; and

                  RE:   Sale of Certain Assets of Bioman Products, Inc.
                        and NOVAMANN International, Inc.

Gentlemen:

         This opinion  letter is being  delivered  pursuant to Section 3.4(b) of
that certain Asset Purchase  Agreement (the  "Purchase  Agreement")  dated May ,
1995 among NOVAMANN International,  Inc., a corporation organized under the laws
of Canada ("Parent"),  Bioman Products,  Inc., a corporation organized under the
laws of Ontario, Canada ("Subsidiary")  (collectively,  "Sellers"),  and EDITEK,
Inc.,  a  Delaware  corporation  ("Purchaser"),  in our  capacity  as counsel to
Sellers in  connection  with the  negotiation,  execution  and  delivery  of the
Purchase  Agreement  and  the  consummation  of  the  transactions  contemplated
therein.

         Capitalized  terms used in this  opinion  letter and not  defined in it
have the respective meanings given to those terms in the Purchase Agreement.

         Based  upon  the  foregoing  and  subject  to  the  qualifications  and
limitations set forth herein, we are of the following opinions:

                  1. Subsidiary is a corporation  duly  incorporated,  organized
and  entitled to conduct  business  under,  and is validly  existing and in good
standing  under  the laws of  Ontario,  Canada.  Parent  is a  corporation  duly
incorporated,  organized and entitled to conduct  business under, and is validly
existing and in good standing under the laws of Canada.

                  2. Parent has all requisite  corporate  power and authority to
own,  operate or lease its properties and to engage in its business as conducted
on the date  hereof,  and is  qualified  or licensed to do business  and in good
standing  in such  jurisdictions  as to which a failure  to be so  qualified  or
licensed would have a material, adverse effect on the Parent.

                  3.       Subsidiary has all requisite corporate power and
authority to own, operate or lease its properties and to engage

in its business as conducted on the date hereof, and is qualified or licensed to
do business and in good standing in such  jurisdictions as to which a failure to
be so  qualified  or  licensed  would  have a  material,  adverse  effect on the
Subsidiary.

                  4.       Parent has good and marketable title to all Parent
Assets, free and clear of all liens, charges, claims and
encumbrances.

                  5. Subsidiary has good and marketable  title to all Subsidiary
Assets (including all names,  marks and other intellectual  property),  free and
clear of all  liens,  charges,  claims  and  encumbrances,  and the  conduct  of
Subsidiary's  business is free from infringement of patents,  trademarks,  trade
names, copyrights or publication rights of others.

                  6. With respect to the Purchase  Agreement,  the  Distribution
and  Supply  Agreement  and any  other  agreements,  instruments  and  documents
executed  and  delivered  by  Sellers,   pursuant  to  the  Purchase   Agreement
(collectively,  together  with the  Purchase  Agreement,  the "Seller  Delivered
Agreements"):

                           (a)      Each of Sellers has the corporate power and
authority to execute and deliver the Seller Delivered  Agreements to which it is
a party and to consummate  the  transactions  contemplated  by, and otherwise to
comply with and perform under, them;

                           (b)     The execution and delivery by each of Sellers
of the Seller Delivered  Agreements,  the consummation by each of Sellers of the
transactions  contemplated by them and each of Seller's other compliance with or
performance  under them have been duly  authorized  by all  necessary  corporate
action  on the part of each of  Sellers  in  compliance  with any  governing  or
applicable  agreements,   instruments  or  other  documents  (including  without
limitation its Articles of Incorporation and Bylaws) and applicable law;

                           (c)      Each of Sellers has duly executed and
delivered the Seller Delivered Agreements;

                           (d)      The transfer instruments included in the
Seller Delivered  Agreements  effectively convey to, and vest in, Purchaser good
and marketable title to and in the Parent Assets and Subsidiary  Assets free and
clear  of  all  liens  and  encumbrances,  except  as  specifically  assumed  by
Purchaser.

                  7.  The  Seller  Delivered   Agreements   (including   without
limitation  the  transfer  instruments  delivered by Sellers with respect to the
Parent Assets and Subsidiary Assets) constitute valid and binding obligations of
Sellers  enforceable against each of them in accordance with their terms, except
as  enforceability  may be limited by  bankruptcy,  insolvency,  reorganization,
moratorium  and other  similar laws relating to or affecting  creditors'  rights
generally,   by  general  equitable  principles   (regardless  of  whether  such
enforceability  is  considered  in a  proceeding  in  equity or at law) or by an
implied covenant of good faith and fair dealing.

                  8. Neither the  execution or delivery of the Seller  Delivered
Agreements  nor the  consummation  by Sellers of the  transactions  contemplated
thereby nor other  compliance  with or performance  under them will (i) conflict
with or result in any breach of any  provision of the Articles of  Incorporation
(as  amended) or Bylaws (as amended) of Parent or  Subsidiary,  (ii) result in a
violation  or breach of, or  constitute  (with or without due notice or lapse of
time or the  happening or  occurrence of any other event) a default by Parent or
Subsidiary,  or permit the  termination  of, or require the consent of any other
party to, or result in the  acceleration  of, or entitle any party to accelerate
(or  give  rise to the  creation  of any  lien,  charge,  security  interest  or
encumbrance upon any properties or assets of Parent or Subsidiary) under, any of
the terms,  conditions  or provisions of any  contract,  note,  bond,  mortgage,
indenture,  license, agreement or other instrument or obligation to which Parent
or  Subsidiary  is a party or by which  either  Parent or  Subsidiary  or any of
either of their  properties  or assets may be bound or (iii)  violate any order,
writ,  injunction,   decree,  statute,  rule  or  regulation  of  any  court  or
governmental  authority applicable to Parent or Subsidiary,  or any of either of
their properties or assets.

                  9. No consent,  approval, order or authorization of, notice to
or permit from, or  registration,  declaration of filing with, any  governmental
authority  or other  person on the part of  either of  Sellers  is  required  in
connection with Sellers'  execution or delivery of the Purchase Agreement or the
other Seller  Delivered  Agreements,  Sellers'  consummation of the transactions
contemplated by them,  Sellers' other compliance with or performance  under them
or to enable  Purchaser  after the Closing  Date to continue to conduct the same
business  conducted by Subsidiary  in a manner which is consistent  with that in
which it is presently conducted by Subsidiary.

                  10.  To  the  best  of  our  knowledge  and  except  as may be
disclosed  in any  schedules  to the  Purchase  Agreement,  neither  Parent  nor
Subsidiary is in violation of any applicable  law,  statute,  ordinance,  order,
rule or regulation promulgated,  or judgment, decree, order, concession,  grant,
permit,  license or other  governmental  authorization  or  approval,  issued or
entered  by any  federal,  state,  provincial  or local  court  or  governmental
authority,  relating to or affecting the operation,  conduct or ownership of the
property or business of Parent or Subsidiary.

                  11. To the best of our  knowledge,  Subsidiary  is in material
compliance  with all Licenses and other  contracts  included in the Assets being
transferred  to Purchaser by Parent and  Subsidiary,  and the Licenses are fully
valid and  enforceable  and are  transferrable  to  Purchaser  and  renewable by
Purchaser on terms as advantageous to Purchaser as to Subsidiary.

                  12. To the best of our  knowledge  and except as  disclosed in
any  schedules to the Purchase  Agreement,  no  litigation  or other  proceeding
against  either of the Sellers or any of the Parent Assets or Subsidiary  Assets
is pending or threatened, and there is no judgment, decree, injunction,  rule or
order of any court, governmental department, commission, agency, instrumentality
or arbitrator  outstanding against Parent or Subsidiary which would individually
or in the aggregate, if adversely determined, have a material, adverse effect on
Subsidiary  or  result in any  claim,  lien or other  encumbrance  on any of the
parent Assets or Subsidiary Assets.

         This opinion letter is delivered in connection with the consummation of
the transactions contemplated in the Purchase Agreement, may be relied upon only
by you and your counsel in connection  therewith,  may not be relied upon by you
for any other purpose or by anyone else for any purpose,  and may not be quoted,
published or otherwise disseminated without our prior written consent.
                                                     Very truly yours,

                                    EXHIBIT C
                           TO ASSET PURCHASE AGREEMENT


         AGREEMENT dated as of May 31, 1995,  between  EDITEK,  INC., a Delaware
corporation, ("EDITEK"), and NOVAMANN INTERNATIONAL INC., a Canadian corporation
("NOVAMANN" is defined below to include  certain other persons and entities) and
Bioman Products Inc., an Ontario corporation ("Bioman").

                                    RECITALS

         A. NOVAMANN is the licensee under certain  license  agreements  between
Her  Majesty  the  Queen in right of  Canada  acting  through  the  Minister  of
Agriculture and Mann Testing Laboratories (the "License Agreements").

         B. Under the License  Agreements,  NOVAMANN  is licensed to make,  use,
sell, and sublicense test kits known as the  Glycopyrrolate  ELISA test kits and
the Cromoglycate  ELISA test kits (both of which are hereinafter  referred to as
the "ELISA Test Kits").

         C. The ELISA Test Kits were manufactured (in part by Bioman and in part
by  subcontractors  to Bioman) and  distributed for NOVAMANN by Bioman using, in
part,  materials  including  Reagents (as defined  below)  supplied to Bioman by
NOVAMANN.

         D. On June 1, 1995,  EDITEK  purchased the assets of Bioman and certain
assets of NOVAMANN,  including  NOVAMANN's entire inventory of Reagents with the
exception of Reagents owned by the Canadian  Government  which shall be provided
to EDITEK as provided herein, with the exception of IMI plate coating technology
which  shall be  acquired  by EDITEK,  if at all,  directly  from  Immunosystems
Division of Milipore Corporation (the "Asset Purchase").

         E. The purchase  price paid by EDITEK for Bioman's  assets was based in
part on EDITEK's  expectation  of  continued  purchases  by NOVAMANN (as defined
below) of Bioman Products (as defined and in the circumstances  described below)
at  historical  volumes  of  purchases  consistent  with  the  current  business
practices of NOVAMANN and the transfer to EDITEK and  continuation  by EDITEK of
Bioman's relationships with suppliers of products sold by Bioman.

         NOW,  THEREFORE,  in  consideration  of the  recitals  and  the  mutual
covenants and promises set out below, the parties agree as follows:



<PAGE>



1.       DEFINITIONS

         1.1  "Bioman  Products"  shall mean all  products  produced,  marketed,
distributed  and/or remarketed by Bioman (and any improved or similar test kits)
on behalf of itself,  NOVAMANN  or any other  supplier  at any time prior to the
Asset Purchase,  including,  without limitation,  ELISA test kits and other test
kits.

         1.2 "NOVAMANN"  shall mean NOVAMANN  INTERNATIONAL,  Inc., any entities
controlled by NOVAMANN, and all officers and key employees thereof.

         1.3  "Reagents"  shall  mean the  reagent  antibodies,  conjugates  and
haptens and any other  reagent or raw  materials  provided by NOVAMANN to Bioman
prior to the date  hereof in  connection  with the ELISA  Test Kits or any other
product of Bioman.

2.       TERM.             The term of this Agreement shall commence upon the
day first above written and shall continue in force for a period
of three (3) years until June 1, 1998.

3.       PRODUCT MANUFACTURE/PURCHASE.

         3.1 Subject to the terms of this  Agreement,  EDITEK  agrees to sell to
NOVAMANN and NOVAMANN agrees to purchase from EDITEK the Bioman Products. EDITEK
shall be the exclusive  supplier to NOVAMANN of ELISA Test Kits,  which NOVAMANN
may not either  manufacture  for itself or acquire from any supplier  other than
EDITEK so long as EDITEK  continues to supply  NOVAMANN  with ELISA Test Kits of
competitive   quality,   quantity,   delivery  and  price.  EDITEK  shall  be  a
nonexclusive supplier to NOVAMANN of Bioman Products other than ELISA Test Kits,
but for Bioman  Products  other than ELISA Test Kits EDITEK shall be  NOVAMANN's
supplier of first resort, provided that EDITEK continues to afford NOVAMANN such
other Bioman Products on competitive  terms, as to quality,  quantity,  delivery
and  price.  EDITEK  shall have the right to cease  selling or to  substantially
change any Bioman Products at any time upon ninety (90) days notice to NOVAMANN,
and  thereafter  NOVAMANN  may buy such  Bioman  Products  from any  supplier it
chooses.  Notwithstanding  anything  herein  contained  NOVAMANN may continue to
purchase from Forensic  Diagnostics  any products  presently  being  supplied to
NOVAMANN by it.

         3.2 EDITEK shall sell Bioman Products to NOVAMANN at prices  consistent
with the prices paid by NOVAMANN  to Bioman for such Bioman  Products  with such
adjustments  made by  EDITEK  as  shall be  commercially  reasonable  under  the
circumstances,  provided that the prices paid by NOVAMANN  shall at all times be
equal to or less than the prices paid by EDITEK's  other  customers  for similar
products. The adjusted prices shall be effective thirty (30)

                                                         2

<PAGE>



days after the date of such notice and shall remain effective until subsequently
adjusted.  To facilitate EDITEK meeting the delivery and quality consistent with
that of Bioman prior to the Asset Purchase, NOVAMANN shall provide EDITEK with a
non-binding  estimation  (the  "NOVAMANN  Requirements  Notice")  of  its  total
requirements  for  Bioman  Products  during the next  calendar  quarter at least
thirty (30) days prior to the beginning of each calendar  quarter.  NOVAMANN may
purchase Bioman Products from other suppliers if Bioman Products are not offered
to NOVAMANN by EDITEK on competitive terms as to quality, quantity, delivery and
price.  NOVAMANN shall notify EDITEK if NOVAMANN  purchases Bioman Products from
other  suppliers on account of EDITEK's  failure to meet price or other terms of
the other suppliers.

         3.3 If EDITEK  requires  additional  Reagents over and above the entire
inventory of NOVAMANN of Reagents  purchased by EDITEK in the Asset  Purchase on
the date hereof,  at the option of EDITEK  NOVAMANN  shall assist  EDITEK to the
best of its ability to manufacture the Reagents,  including, without limitation,
providing  EDITEK  with all trade  secrets  which  NOVAMANN  is free to disclose
without  breach  of  confidentiality  obligations  to third  parties  and  other
information  required for  manufacturing  the  Reagents,  in which case NOVAMANN
shall use its best  efforts  to obtain  the  consent  of such  third  parties to
disclosure to, and use by EDITEK. NOVAMANN hereby represents that the only trade
secrets  NOVAMANN  is not free to  disclose  without  breaching  confidentiality
obligations  to third parties are listed in Schedule 3.3 hereto.  NOVAMANN shall
not  manufacture  or sell to any  person  or  entity  any  Reagents,  except  as
specifically requested by EDITEK.

4.       CERTAIN NOVAMANN OBLIGATIONS; RESERVATION OF RIGHTS.

         4.1 NOVAMANN shall not manufacture any Bioman Products, whether for its
own use or for resale.  Except as provided in Sections  3.1 and 3.2,  during the
Term,  NOVAMANN will not purchase,  whether for its own use or for resale or act
as agent or broker or otherwise arrange for sale by others, any Bioman Products.

         4.2 Except as provided in Sections 3.1, 3.2 and 8.1(b),  NOVAMANN shall
not contact,  discuss,  negotiate  with,  or solicit any offer from,  any Bioman
Supplier  relating to any purchase,  sale,  distribution  or  manufacture of any
Bioman Products.  NOVAMANN shall take any reasonable  action requested by EDITEK
to assist EDITEK to cause the arrangements,  agreements,  history of dealing and
other  relationships  between  EDITEK and any Bioman  Supplier to be transferred
from Bioman to EDITEK,  at EDITEK's  expense.  Neither shall NOVAMANN  knowingly
take  any  action  or  make  any  communication  that  would  have a  reasonable
possibility  of disrupting  any  arrangement,  agreement,  history of dealing or
other relationship between EDITEK and any Bioman Supplier. A

                                                         3

<PAGE>



"Bioman  Supplier"  is any  person or entity  who at any time prior to the Asset
Purchase sold products to Bioman for its own use or for resale by Bioman.

         4.3  NOVAMANN  hereby  appoints  EDITEK  as the  exclusive  distributor
worldwide  of any  products  manufactured,  purchased  for  resale or  otherwise
distributed  by  NOVAMANN,  if at any time prior to the Asset  Purchase,  Bioman
acted as a distributor or purchased such products from NOVAMANN.

5.  CONTINUITY.  The purchase price paid by EDITEK for Bioman's assets was based
in part on EDITEK's expectation of (i) continued purchases by NOVAMANN (assuming
continued  sales by  NOVAMANN  at  historical  levels)  of  Bioman  Products  at
historical  volumes  consistent with the current business  practices of NOVAMANN
prior to the Asset Purchase and (ii) the transfer to EDITEK and  continuation by
EDITEK of the  relationship  of Bioman with suppliers of Bioman Products sold by
Bioman  prior to the Asset  Purchase.  In the event that in any year  during the
term of this  Agreement  purchases  by  NOVAMANN  are less  than the  historical
volumes of purchases by NOVAMANN from Bioman or if NOVAMANN shall fail to comply
with any provision of Section 4 of this Agreement  without just cause,  NOVAMANN
shall rebate to EDITEK a part of the purchase price of the assets paid by EDITEK
sufficient to equitably  compensate EDITEK,  except to the extent that continued
purchases  by  NOVAMANN  of  Bioman  Products  are  reduced  as a result  of (i)
diminished  sales by  NOVAMANN  of  services  requiring  the use of the types of
products  covered by this  Agreement,  (ii)  failure  by EDITEK to offer  Bioman
Products to NOVAMANN on competitive terms as to quality,  quantity,  delivery or
price,  or (iii) the  availability  from other  suppliers of products  utilizing
technology  which the industry as a whole would  consider new, which provides an
improvement over existing technology,  and which is not made available by EDITEK
to NOVAMANN.  Both NOVAMANN and EDITEK shall act reasonably and in good faith to
reach  agreement on the amount of such rebate prior to EDITEK bringing any legal
action.

6.       ORDERS/INVOICING/SHIPMENT.

         6.1 Each party  shall  provide the other with  written  orders on forms
acceptable to one another for products to be purchased from one another.

         6.2 EDITEK and NOVAMANN  shall  invoice the other for each  shipment of
products at the time it is  delivered.  The full amount of each invoice shall be
payable  within  thirty  (30) days of the date of  delivery  at the  purchaser's
specified  location.  All products  shall be invoiced at prices  established  in
accordance  with this  Agreement  as of the  earlier  of the date of  invoice or
shipment, plus all applicable taxes.


                                                         4

<PAGE>



         6.3      All products shall be shipped F.O.B. purchaser's desti-
nation.  The destination of the shipment shall be specified by in
the applicable order.  "F.O.B." is a delivery term meaning that
the purchaser shall have the risk of loss, damage and/or delay in
shipment until the Product is properly delivered to the
purchaser's destination.

7.       WARRANTIES.

         7.1 Each  product  sold by one  party to the other  hereunder  shall be
subject to the  warranties  inserted by the seller of the product into or on the
product  packaging.  Each  party  shall  assign  to  the  other  any  assignable
warranties  of  manufacturers,  distributors  or other  persons or entities with
respect to products sold hereunder.

THE  EXPRESS  WARRANTIES  SET FORTH  ABOVE ARE MADE IN LIEU OF ANY AND ALL OTHER
WARRANTIES,  VERBAL OR WRITTEN,  EXPRESS OR IMPLIED,  RELATING TO THE PRODUCT OR
THE  WORKMANSHIP  OR MATERIALS  INCORPORATED  THEREIN.  EDITEK AND NOVAMANN EACH
DISCLAIM ANY AND ALL OTHER  WARRANTIES  APPLICABLE  TO THE  PRODUCTS  IMPLIED BY
OPERATION OF LAW OR OTHERWISE,  INCLUDING,  BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY AND/OR FITNESS FOR A PARTICULAR PURPOSE.

The  provisions  of  this  Section  7  shall  survive  the  termination  of this
Agreement.

8.       COVENANT NOT TO COMPETE.

         8.1 (a)  NOVAMANN  covenants  that for a  period  of  three  (3)  years
beginning on the date hereof, it shall not, within the United States, Canada, or
any other place in the world (the  "Noncompetition  Area"),  without the written
consent of EDITEK, (1) manufacture,  distribute, market or sell ELISA Test Kits,
or otherwise compete in any line of business similar to the business acquired by
EDITEK from  Bioman;  (2)  distribute  the products of any third party if at any
time Bioman acted as a distributor of such products or similar products for such
third party; (3) be an owner of a controlling interest in a partnership, limited
liability  company,  corporation  or other entity which performs any of the acts
described  in (1) or (2)  above,  except  that  NOVAMANN  may own a  controlling
interest in a  partnership,  limited  liability  company,  corporation  or other
entity,  of which (a) less than one half (1/2) of the gross revenue  arises from
the  performance  of the acts  described in (1) or (2) above in countries  other
than the United States or Canada,  and (b) none of the gross revenue arises from
the  performance  of the acts described in (1) or (2) above in the United States
or Canada;  or (4) assist others in performing  any of the acts described in (1)
through (3) above. NOVAMANN agrees to use its best efforts to prevent any entity
in which it owns an interest other than a controlling  interest from  performing
any of the acts described in

                                                         5

(1) or (2) above. In the event the Noncompetition  Area specified above shall be
determined by judicial action to define too broad a territory to be enforceable,
the country or  countries  causing  the  territory  to be overly  broad shall be
deleted and the Noncompetition  Area shall be the remaining  countries or areas.
In the event the  Noncompetition  Area  specified in the first  sentence of this
paragraph (a) is  determined by judicial  action to define too broad a territory
to be enforceable and the Noncompetition Area cannot be reformed pursuant to the
immediately  preceding  sentence to define a territory which is not too broad to
be enforceable, the Noncompetition Area shall be the United States and Canada.

         (b) It is  recognized  that NOVAMANN may from time to time be presented
with opportunities to develop,  distribute or manufacture technology or products
within the  Noncompetition  Area,  which  activities  would be prohibited by the
terms of this  Section 8.1.  During the term  hereof,  NOVAMANN may present such
opportunities to EDITEK under such confidentiality  agreements and circumstances
as are mutually acceptable to NOVAMANN and EDITEK. EDITEK agrees to negotiate in
good faith with NOVAMANN to pursue such opportunities;  provided,  however, that
if, after such  negotiations,  EDITEK chooses not to pursue such  opportunities,
NOVAMANN  shall  continue to be prohibited by the terms of this Section 8.1 from
independently  pursuing  such  opportunities;  provided  further  that if EDITEK
chooses  not to  pursue  such  opportunities,  NOVAMANN  may  approach  EDITEK's
suppliers  with such  opportunities  with the consent of EDITEK  which shall not
unreasonably  be denied or delayed.  Denial of consent  shall be  reasonable  if
NOVAMANN's or such supplier's pursuit of such opportunities would be detrimental
to EDITEK.

         (c)  Notwithstanding  the  provisions  of  Section  8.1(a),  (1)  Smith
Laboratory  Service Limited in Toronto may continue its current minimal level of
business  in  competition  with  Bioman,  and (2) the  member  of the  board  of
directors  of Parent who  currently  indirectly  acts as a supplier in Mexico of
Sepelco products may continue to conduct his present business activities without
there being a breach of this agreement.

         8.2 NOVAMANN  acknowledges that the covenants  included Section 9.1 are
critical  to the success of EDITEK and that  violation  of the  covenants  would
immeasurably  damage  EDITEK.  EDITEK shall be entitled to an  injunction  to be
issued by any court of competent jurisdiction enjoining and restraining NOVAMANN
from committing any violation or threatened  violation of this Section,  without
the necessity of posting bond. The prevailing party in such litigation shall, in
addition to any other rights or remedies  available to it, at law or  otherwise,
be entitled to  reimbursement  from the losing party of court costs,  attorney's
fees,  and other  expenses  incurred,  if and to the  extent  awarded by a Court
having jurisdiction.

insolvent,  or if any trustee or receiver for such party or for any  substantial
part of its  property be appointed  at such  party's  request,  or if any person

trustee or receiver for such party or for any  substantial  part of its property
be  appointed at the request of a third party and such  appointment  or petition

reimbursed  for  any and  all  expenses  incurred  by it  (including  reasonable
attorneys' fees and expenses) in enforcement of the terms and provisions of this
Agreement.

         9.4      The exercise by a party of any one or more of the

quent exercise of any one or more of the other remedies herein
provided.  All remedies provided for in this Agreement are

                                                         7

EDITEK, Inc.

Re:   Private Offering Of Common Stock

Gentlemen:

In connection with the offer (the  "Offering")  and proposed  issuance of shares
("Common  Shares")  of  common  stock  of  EDITEK,  Inc.  (the  "Company"),  the
undersigned  prospective  investor ("the Investor") and the Company hereby agree
as follows:

1.    Subscription.  The  Investor  hereby  subscribes  for the  purchase of the
      Common Shares and agrees to purchase the aggregate number of Common Shares
      set forth on the signature  page of this  Agreement.  The Company,  in its
      sole discretion and for any reason,  may accept or reject this purchase in
      whole or in part at any time not later than 10 days after  receipt of this
      Agreement.

2.    Listing  of  Shares.  The  Company  agrees  to make any  required  listing
      application  with the American Stock Exchange to qualify the Common Shares
      for trading on the AMEX and use its best efforts to effect such listing.

3.    Payment Of Purchase Price. The Investor shall pay for the Common Shares by
      either wire  transfer of funds to the Company at a time  designated by the
      Company  (the  "Closing").  The number of Common  Shares  issuable  to the
      Investor  shall be equal to the  aggregate  purchase  price of the  Common
      Shares divided by the purchase price per share of the Common Shares,  less
      any fractional  shares.  The aggregate purchase price of the Common Shares
      shall  be  $600,002.25  less an  amount  corresponding  to any  fractional
      shares.  The purchase  price per share of the Common Shares shall be equal
      to Seventy Five  Percent  (75%) of the Market Price of the common stock of
      the Company.  The "Market  Price" as used in this  Section  shall mean the
      average of the closing  prices of the  Company's  Common Stock on the five
      (5) trading  days  immediately  prior to February 1, 1996 as quoted in The
      Wall Street Journal.
                                                                        
      The  Company  undertakes  to deliver  certificates  for the Common  Shares
      within five (5) business days following Closing.

4.    Company's  Conditions.  The  Company's  obligation  to issue  and sell the
      Common  Shares shall be subject to the  satisfaction  (or waiver by it) of
      the following conditions precedent:

      a)   Performance.  The Investor shall have tendered payment for the Common
           Stock.



<PAGE>



      b)   Representations.   Each  representation  and  warranty  made  by  the
           Investor in this Agreement  shall be true and correct in all material
           respects as though made on and as of the Closing Date.

      c)   Legality.  No  change  shall  have  occurred  in  any  law,  rule  or
           regulation  that would prohibit the  consummation  of any transaction
           contemplated hereby.

      d)   Litigation.  No action,  proceeding or investigation  shall have been
           instituted or threatened nor shall any order, judgment or decree have
           been  issued or be  proposed  to be issued  by any  court,  agency or
           authority to set aside, restrain,  enjoin or prevent the consummation
           of any transaction contemplated hereby.

5.    Representations  and Warranties.  The Investor makes the  representations,
      declarations and warranties set forth in this Section with the intent that
      the same may be relied upon in determining the Investor's suitability as a
      purchaser of the Common  Shares.  If the Investor  includes or consists of
      more than one person or entity,  the  obligations of the Investor shall be
      joint and several and the  representations and warranties herein contained
      shall be deemed  to be made by and be  binding  upon  each such  person or
      entity and their respective heirs, executors,  administrators,  successors
      and assigns.

      a)   No  Regulatory  Review.  The Investor is aware that this is a limited
           private offering and that no federal,  state or other agency has made
           any finding or determination as to the fairness of the investment nor
           made any recommendation or endorsement of the Common Shares.

      b)   Ability  to  Evaluate.  The  Investor,  by reason  of the  Investor's
           knowledge  and  experience  in  financial  and business  matters,  is
           capable of  evaluating  the risks and merits of an  investment in the
           Common Shares.

      c)   Investment  Intent.  The Investor  acknowledges  that the purchase of
           Common Shares hereunder is being made for the Investor's own account,
           for  investment  purposes only and not with the present  intention of
           distributing for reselling the Common Shares in whole or in part. The
           Investor  further  understands  that the Common  Shares are not being
           sold to the Investor in a transaction registered under the Securities
           Act,  or  any  state  securities  laws.  As a  result,  the  Investor
           understands  that there will be restrictions on the transfer and sale
           of  the  Common  Shares.  Investor  hereby  agrees  to  exercise  the
           registration  rights  granted  hereby,  and to sell the Common Shares
           pursuant  to such  registration,  in a  manner  consistent  with  the
           representations  and  warranties  made  by  Investor  to the  Company
           hereunder.  Investor  understands  that the SEC may in its discretion
           comment on  certain  aspects of the  Registration  Statement  and the
           transaction   and  that  such   comments   may  cause  delay  in  the
           Registration Statement becoming effective.  The Company shall have no
           liability to Investor on account of any delays initiated by the SEC.

                                                         2

<PAGE>



      d)   Investment  Information.  The  Investor  has  received  and  reviewed
           pertinent  information  regarding  the  Company,  including  the most
           recent  SEC Forms  10-K and 1O-Q  filed by the  Company  prior to the
           execution  of this  Agreement  and is  capable of  understanding  and
           evaluating  the  information  contained  therein.  Specifically,  the
           Investor is fully aware of the risks  relating to the business of the
           Company and purchase of the Common  Shares.  The  Investor  will rely
           solely upon his independent  investigation and analysis in making the
           decision to purchase the Common Shares.  In  particular,  and without
           limiting the generality of the foregoing, the Investor has not relied
           on, and the  Investor's  decision to subscribe  for Common Shares has
           not been  influenced  by:  (i)  newspaper,  magazine  or other  media
           articles  or reports  related to the  Company or its  business;  (ii)
           promotional  literature  or other  materials  used by the Company for
           sales or  marketing  purposes,  or (iii)  any other  written  or oral
           statement  of the  Company or persons  purporting  to  represent  the
           Company.  The Investor has had the opportunity to discuss all aspects
           of this transaction  with management of the Company,  has made or has
           had the  opportunity to make such inspection of the books and records
           of the Company as the  Investor has deemed  necessary  in  connection
           with this  investment,  and any questions asked have been answered to
           the satisfaction of the Investor.

      e)   Confidentiality.  The  Investor  understands  that  the  Offering  is
           confidential.  The Investor has not  distributed  information  on the
           Offering to anyone other than such legal or financial advisors as the
           Investor  has  deemed   necessary   for  purposes  of  evaluating  an
           investment in the Common Shares.

      f)   Authorization  and  Formation  of  Investor.   The  Investor,   if  a
           corporation,  partnership, trust or other form of business entity, is
           authorized  and  otherwise  duly  qualified  to purchase and hold the
           Common  Shares and such entity has not been  formed for the  specific
           purposes of acquiring Common Shares in the Offering.  If the Investor
           is one of the  aforementioned  entities,  it hereby  agrees that upon
           request of the Company it will supply the Company with any additional
           written information that may be requested by the Company.

      g)   Accredited Investor Status. The Investor is an "accredited  investor"
           as such term is defined in Rule 501(a) of  Regulation D under the Act
           and within the meaning of similar  regulations under state securities
           laws. If the Investor is an individual, he or she is of majority age.
           If the Investor is an entity,  the person  executing this  Securities
           Purchase Agreement on behalf of the Investor is of majority age.

6.    Reliance  on  Representations  and  Warranties:  Indemnity.  The  Investor
      understands  that  the  Company  will  rely  on  the  representations  and
      warranties  of the Investor  herein in  determining  whether a sale of the
      Common Shares to the Investor is in compliance with federal and applicable
      state securities laws. The Investor hereby agrees to indemnify the Company
      and its  affiliates,  and hold the Company and its  affiliates  and agents
      harmless from and against any and all liability,  damage,  cost or expense
      (including  reasonable  attorneys' fees) incurred on account of or arising
      out of: (a) any inaccuracy in the Investor's

                                                         3

<PAGE>



      declarations,  representations and warranties set forth in this Agreement;
      (b) the  disposition  of any of the Common  Shares which the Investor will
      receive,  contrary to the  Investor's  declarations,  representations  and
      warranties in this Agreement;  (c) any lawsuit or proceeding  based upon a
      claim  that  said   declarations,   representations   or  warranties  were
      inaccurate  or  misleading  or otherwise  cause for  obtaining  damages or
      redress from the Company or any of its  affiliates or the  disposition  of
      all or any part of the  Investor's  Common  Shares and (d) the  Investor's
      failure to fulfill any or all of the Investor's obligations herein.

7.    Updating Information. All of the information set forth herein with respect
      to the Investor, including, without limitation, all of the representations
      and  warranties  set forth in Section 5, is correct and complete as of the
      date  hereof  and,  if  there  should  be  any  material  change  in  such
      information  prior to the acceptance of this  subscription by the Company,
      the Investor will immediately furnish the revised or corrected information
      to the Company.

8.    Notices.  Any  notice  or  other  communications   required  or  permitted
      hereunder shall be sufficiently given if in writing and sent by registered

                          REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT,  dated as of February 1, 1996 (this
"Agreement"),  is made between EDITEK,  Inc., a corporation  organized under the
laws of Delaware (the "Company"), and Harry McCoy (the "Investor").

                              W I T N E S S E T H:

         WHEREAS,  the Investor is purchasing  235,295  shares (the "Shares") of
Common Stock of the Company; and

         WHEREAS, the Company is agreeing to provide certain registration rights
under the  Securities  Act of 1933,  as amended,  and the rules and  regulations
thereunder,  or any similar  successor  statute  (collectively,  the "Securities
Act"), and applicable state securities laws with respect to the Shares.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants  contained  herein  and other  good and  valuable  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the
Investor hereby agree as follows:

         1.       Definitions.

                  (a)      As used in this Agreement, the following terms shall 
have the following meanings:

                           (i)  "Register,"   "registered,"  and  "registration"
refer  to a  registration  effected  by  preparing  and  filing  a  Registration
Statement  or  Statements  in  compliance   with  the  Securities  Act  on  such
appropriate registration form promulgated by the Commission as shall be selected
by the  Company  and  the  declaration  or  ordering  of  effectiveness  of such
Registration  Statement by the United States Securities and Exchange  Commission
("SEC") and applicable state laws.

                           (ii)     "Registrable Securities" means the Shares.

                           (iii)  "Registration  Statement" means a registration
statement under the Securities Act registering securities of the Company.

         2.       Registration.

                  (a)  Piggy-Back  Registrations.  Subject to the  provisions of
Sections 3 and 4 hereof,  if at any time the Company shall  determine to prepare
and file with the SEC a

<PAGE>



Registration  Statement  relating to an offering under the Securities Act of any
of its equity  securities  for its own account or the  account of others,  other
than on Form  S-4 or Form S-8 or  their  then  equivalents  relating  to  equity
securities to be issued solely in connection  with any acquisition of any entity
or business or equity  securities  issuable in  connection  with stock option or
other employee  benefit  plans,  the Company shall send to the Investor who owns
Registrable  Securities  written  notice of such  determination  and,  if within
twenty (20) days after receipt of such notice,  the Investor shall so request in
writing,  the Company  shall include in such  Registration  Statement all or any
part of the Investor's  Registrable  Securities that the Investor requests to be
registered,  except that if, in connection with any underwritten public offering
for the account of the Company the managing  underwriter(s) thereof shall impose
a  limitation  on the number of shares of Common  Stock which may be included in
the Registration  Statement  because,  in such  underwriter(s)'  judgment,  such
limitation  is  necessary  to effect an orderly  public  distribution,  then the
Company shall be obligated to include in such  Registration  Statement only such
limited portion, if any, of the Registrable Securities with respect to which the
Investor  has  requested  inclusion  hereunder.  Any  exclusion  of  Registrable
Securities and other  securities  having  registration  rights shall be made pro
rata among the Investor and other  shareholders  seeking to include  Registrable
Securities and other securities having  registration rights and in proportion to
the number of Registrable  Securities and other securities  having  registration
rights sought to be included in such registration;  provided,  however, that the
Company  shall not exclude  any  Registrable  Securities  unless the Company has
first excluded all outstanding  securities the holders of which are not entitled
to  inclusion  of  securities  in  such  Registration  Statement.  No  right  to
registration  of  Registrable  Securities  under  this  Section  2(a)  shall  be
construed to limit any  registration  required  under  Section 2(b) hereof.  The
obligations  of the Company  under this  Section 2(a) shall  terminate  upon the
earlier of (i)  February  1, 1999 or (ii) after the  Company  has  afforded  the
opportunity for the Investor to exercise  registration rights under this Section
2(a) for two  registrations;  provided,  however,  that if the  Investor has any
Registrable  Securities  excluded from any Registration  Statement in accordance
with this  Section  2(a),  the  Investor  shall be  entitled  to  include  in an
additional   Registration   Statement  filed  by  the  Company  the  Registrable
Securities so excluded.

                  (b)  Immediate  Registration.  Subject  to the  provisions  of
Sections 3 and 4 hereof,  the  Company  shall  prepare  and file a  Registration
Statement  with the SEC within fifteen (15) business days after the date hereof;
provided, however, that such registration statement need not be filed until five
(5)  business  days  after  the  Investor  has  provided  the  Company  with all
information  reasonably  requested  by  the  Company  in  connection  with  such
registration.

                  (c) If any  registration is  underwritten,  the Investor shall
pay all  underwriting  discounts and commissions with respect to the Registrable
Securities of the Investor  included  therein and the fees and expenses of legal
counsel of the Investor.


                                                         2

                  (d)  Nothing  herein  shall  limit the right of the Company to
grant registration rights to any other person or entity and to include shares of
such person or entity on any Registration Statement.

         3.  Obligations of the Company.  In connection with the registration of
the Registrable Securities under this Agreement, the Company shall:

                  (a) prepare promptly and file with the SEC promptly (but in no
event later than 15 business  days after the  Closing  Date of the  transactions
contemplated by the Purchase  Agreement) a Registration  Statement or Statements
with  respect  to  all  Registrable  Securities  to  be  included  therein,  and
thereafter  use its best efforts to cause the  Registration  Statement to become
effective as soon as reasonably possible after such filing. If such Registration
Statement is filed pursuant to Rule 415, the Company shall keep the Registration
Statement  effective pursuant to Rule 415 at all times until such date as is two
years after the date such  Registration  Statement is first ordered effective by
the SEC. In any case, the  Registration  Statement  (including any amendments or
supplements  thereto and  prospectuses  contained  therein) filed by the Company
shall not contain  any untrue  statement  of a material  fact or omit to state a
material fact required to be stated therein, or necessary to make the statements
therein,  in light of the circumstances in which they were made, not misleading;
provided,  however,  that,  subject to the  conditions set forth in Section 4(a)
below,  the Investor may notify the Company in writing that it wishes to exclude
all or a portion of its Registrable Securities from such Registration Statement.

                  (b) prepare and file with the SEC such  amendments  (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus  used  in  connection  with  the  Registration  Statement  as  may be
necessary to keep the Registration  Statement  effective at all times until such
date as is two years after the date such Registration Statement is first ordered
effective by the SEC, and, during such period, comply with the provisions of the
Securities Act with respect to the disposition of all Registrable  Securities of
the Company covered by the Registration Statement until such time as all of such
Registrable  Securities have been disposed of by the Investor in accordance with
the  intended  methods  of  disposition  by the  Investor  as set  forth  in the
Registration Statement.

                  (c) furnish to the Investor whose  Registrable  Securities are
included in the Registration  Statement,  such number of copies of a prospectus,
including a preliminary  prospectus,  and all amendments and supplements thereto
promptly  upon  approval  thereof  by the SEC and such  other  documents  as the
Investor may reasonably  request in order to facilitate  the  disposition of the
Registrable  Securities owned by the Investor;  The Company shall provide copies
of all such  documents  upon  approval  thereof  by the SEC to  counsel  for the
Initial Investor at such address designated in writing by the Initial Investor;

                  (d)  (i)  register  or  qualify,   or  obtain  exemption  from
registration or  qualification  for, the Registrable  Securities  covered by the
Registration  Statement  under  such other  securities  or blue sky laws of such
jurisdictions as required for sale of the Registrable

                                                         3

<PAGE>



Securities by the Investor as the Investor reasonably requests, (ii) prepare and
file  in  those   jurisdictions   such  amendments   (including   post-effective
amendments) and  supplements,  (iii) take such other actions as may be necessary
to maintain such  registrations or  qualifications  in effect at all times until
February  1,  1998 and (iv)  take all  other  actions  reasonably  necessary  or
advisable to qualify the Registrable  Securities for sale in such  jurisdictions
or to  otherwise  permit the Holders to dispose of the  Registrable  Securities;
provided,  however,  that  the  Company  shall  not be  required  in  connection
therewith  or as a  condition  thereto  to (I)  qualify  to do  business  in any
jurisdiction  where it would not  otherwise  be required to qualify but for this
Section 3(d), (II) subject itself to general taxation in any such  jurisdiction,
(III) file a general  consent  to  service of process in any such  jurisdiction,
(IV) make any change in its charter or by-laws,  which in each case the Board of
Directors of the Company  determines to be contrary to the best interests of the
Company and its stockholders or (V) subject any officer, director or shareholder
to any penalty or risk of  forfeiture  other than those  penalties  and risks to
which  officers and  directors  are  ordinarily  liable in a public  offering of
securities;

                  (e) in  the  event  the  Investor  shall  select  one or  more
underwriters for the offering,  or an underwritten  public offering is conducted
pursuant to Section 2(a) hereof, enter into and perform its obligations under an
underwriting   agreement  in  usual  and  customary  form,  including,   without
limitation,  customary  indemnification and contribution  obligations,  with the
managing underwriter of such offering;

                  (f) as promptly as  practicable  after  becoming aware of such
event,  notify  the  Investor  if the  Investor  continues  to hold  Registrable
Securities  being sold  pursuant to such  registration  of the  happening of any
event of which the Company has  knowledge,  as a result of which the  prospectus
included in the Registration  Statement,  as then in effect,  contains an untrue
statement of a material  fact or omits to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under  which they were  made,  not  misleading,  and use its best
efforts  promptly  to prepare a  supplement  or  amendment  to the  Registration
Statement to correct such untrue statement or omission,  and deliver a number of
copies of such  supplement  or  amendment  to the  Investor as the  Investor may
reasonably request;

                  (g) as promptly as  practicable  after  becoming aware of such
event,  notify  the  Investor  if the  Investor  continues  to hold  Registrable
Securities  being sold  pursuant  to such  registration  (or, in the event of an
underwritten  offering, the managing underwriters) of the issuance by the SEC of
any  stop  order  or  other  suspension  of  effectiveness  of the  Registration
Statement at the earliest possible time;

                  (h)  furnish  on the  date  that  Registrable  Securities  are
delivered  to an  underwriter  for  sale in  connection  with  the  Registration
Statement  (i) a  letter,  dated  such  date,  from  the  Company's  independent
certified  public  accountants in form and substance as is customarily  given by
independent  certified  public  accountants  to  underwriters  in an underwriter
public offering, addressed to the underwriters; and (ii) an opinion, dated such

                                                         4

<PAGE>



date, from counsel  representing  the Company for purposes of such  Registration
Statement,  in form and  substance as is  customarily  given in an  underwritten
public offering, addressed to the underwriters and the Investor;

                  (i)  use  its  best  efforts  either  to  (i)  cause  all  the
Registrable Securities covered by the Registration Statement to be listed on the
American  Stock  Exchange or another  national  securities  exchange and on each
additional  national  securities  exchange on which similar securities issued by
the  Company  are  then  listed,  if any,  if the  listing  of such  Registrable
Securities  is then  permitted  under the rules of such  exchange or (ii) secure
designation  of all  the  Registrable  Securities  covered  by the  Registration
Statement as a National  Association of Securities Dealers Automated  Quotations
System  ("NASDAQ")  "national market system security" within the meaning of Rule
11Aa2-1 of the SEC under the  Securities  Exchange Act of 1934,  as amended (the
"Exchange Act"),  and the quotation of the Registrable  Securities on the NASDAQ
National Market System or, if, despite the Company's best efforts to satisfy the
preceding  clause (i) or (ii),  the Company is  unsuccessful  in satisfying  the
preceding  clause  (i) or (ii),  to  secure  listing  on a  national  securities
exchange or NASDAQ authorization and quotation for such Registrable Securities;

                  (j)  provide a transfer  agent and  registrar,  which may be a
single entity, for the Registrable  Securities not later than the effective date
of the Registration Statement;

                  (k) cooperate with the managing  underwriter or  underwriters,
if any, to facilitate the timely preparation and delivery of certificates to the
transferees to whom such Registrable  Securities are being sold (not bearing any
restrictive  legends)  pursuant to the  denominations or amounts as the case may
be, and registered,  in such names as the managing  underwriter or underwriters,
if any, or the Investor may reasonably request;  and, within three business days
after a Registration  Statement which includes Registrable Securities is ordered
effective by the SEC, the Company  shall  deliver,  or shall cause legal counsel
selected by the Company to deliver,  to the transfer  agent for the  Registrable
Securities (with copies to the Investor whose  Registrable  Securities are being
sold) instructions to the transfer agent to issue new stock certificates without
a legend to such transferees and an opinion of such counsel that the shares have
been registered; and

                  (l) take all other  reasonable  actions  necessary to expedite
and  facilitate  disposition  by  the  Investor  of the  Registrable  Securities
pursuant to the Registration Statement.

                  (m) Notwithstanding the foregoing,  the Company's  obligations
in connection with the  registration of Registrable  Securities shall be limited
as follows:

                           (i) The  Company  shall not be  obligated  under this
Agreement to register or include in any registration Registrable Securities that
the Investor has  requested to be  registered  if the Company  shall furnish the
Investor  with a written  opinion  of  counsel  reasonably  satisfactory  to the
Investor, that all Registrable Securities that the Investor holds

                                                         5

<PAGE>



may be publicly offered,  sold or distributed without registration under the Act
pursuant to Rule 144 without restriction as to the amount of securities that can
be sold.

                           (ii) The Company's  obligation  to amend,  supplement
and  cause  to  continue  to be  effective  any  registration  statement  may be
suspended,  for a  reasonable  period of time,  not to  exceed  45 days,  if the
Company  has been  advised in writing by  independent  legal  counsel  that such
filing would require the disclosure of a material transaction or other facts and
the Board of Directors of the Company  determines  reasonably  and in good faith
that such  disclosure  would have a  material,  adverse  effect on the  Company;
provided,  however,  that the  Company  shall  not under  any  circumstances  be
permitted  to  exercise  such  rights more than two (2) times in any twelve (12)
month period.  The Company shall  immediately  notify in writing the Investor if
the  Investor   continues  to  hold  Registrable   Securities  covered  by  such
registration  statement of such  determination,  and the Investor shall maintain
the confidentiality of such notice and shall cease all trading in the securities
of the  Company  until the Company  notifies  the  Investor in writing  that the
circumstances  that caused such suspension or postponement are no longer present
and that the Registration  Statement is currently  effective.  The Company shall
use its best efforts to promptly  take all such  actions  necessary to eliminate
any such suspension or postponement as soon as reasonably possible.

                           (iii) The Company may in its discretion  grant to any
owner of securities of the Company registration rights of any kind or nature.


         4. Obligations of the Investor.  In connection with the registration of
the Registrable Securities, the Investor shall have the following obligations:

                  (a) It shall be a condition  precedent to the  obligations  of
the Company to take any action  pursuant to this  Agreement  with respect to the
Investor  that the Investor  furnish to the Company such  information  regarding
itself,  the  Registrable  Securities  held by it and  the  intended  method  of
disposition  of the  Registrable  Securities  held by it as shall be  reasonably
required to effect the  registration of the  Registrable  Securities and execute
such  documents  in  connection  with  such  registration  as  the  Company  may
reasonably  request.  At least fifteen (15) days prior to the first  anticipated
filing date of the Registration Statement, the Company shall notify the Investor
of the  information  the Company  requires  from the  Investor  (the  "Requested
Information")  if the Investor elects to have any of the Investor's  Registrable
Securities included in the Registration  Statement.  If within five (5) business
days prior to the filing  date the  Company  has not  received a signed  writing
containing  the Requested  Information  from the Investor  (the  "Non-Responsive
Investor"),  then  the  Company  may  file the  Registration  Statement  without
including Registrable Securities of the NonResponsive Investor;

                  (b)  The  Investor  by  the   Investor's   acceptance  of  the
Registrable  Securities  agrees to  cooperate  with the  Company  as  reasonably
requested by the Company in connection

                                                         6

<PAGE>



with the preparation and filing of the Registration Statement hereunder,  unless
the Investor has notified the Company in writing of the  Investor's  election to
exclude  all of the  Investor's  Registrable  Securities  from the  Registration
Statement;

                  (c) In the event the  Company  or the  holders  of  securities
being  registered  determine  to  engage  the  services  of  an  underwriter  in
accordance  with Section 2(b) hereof,  or in  connection  with any  underwritten
public  offering  pursuant to Section 2(a) hereof,  the Investor agrees to enter
into and perform the Investor's obligations under an underwriting  agreement, in
usual   and   customary   form,   including,   without   limitation,   customary
indemnification and contribution  obligations,  with the managing underwriter of
such offering and take such other actions as are reasonably required in order to
expedite or facilitate the disposition of the Registrable Securities, unless the
Investor  has  notified  the  Company in writing of the  Investor's  election to
exclude  all of the  Investor's  Registrable  Securities  from the  Registration
Statement,  and the Company shall have no obligation to register the Registrable
Securities if the Investor fails to comply with this paragraph;

                  (d) The Investor  agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind  described in Section 3(f)
and 3(g), the Investor will immediately  discontinue  disposition of Registrable
Securities  pursuant to the  Registration  Statement  covering such  Registrable
Securities  until the Investor's  receipt of the copies of the  supplemented  or
amended  prospectus  contemplated by Section 3(f) or 3(g) and, if so directed by
the  Company,  the Investor  shall,  at the option of the  Investor,  either (i)
deliver to the Company or (ii) destroy (and deliver to the Company a certificate
of  destruction)  all copies in the  Investor's  possession,  of the  prospectus
covering  such  Registrable  Securities  current  at the time of receipt of such
notice; and

                  (e) The Investor  may not  participate  and the Company  shall
have no obligation to register the Registrable Securities of the Investor in any
underwritten  registration  hereunder unless the Investor (i) agrees to sell the
Investor's  Registrable  Securities  on the basis  provided in any  underwriting
arrangements  approved  by the  Investor  entitled  hereunder  to  approve  such
arrangements,  (ii)  completes  and  executes  all  questionnaires,   powers  of
attorney,  indemnities,  underwriting  agreements and other documents reasonably
required under the terms of such  underwriting  arrangements and (iii) agrees to
pay its pro rata share of all underwriting  discounts and commissions applicable
with  respect  to its  Registrable  Securities,  in each case to the  extent not
payable by the Company pursuant to the terms of this Agreement.

         5.  Expenses of  Registration.  All expenses  (other than  underwriting
discounts and commissions or brokerage  commissions) incurred in connection with

         6.  Indemnification.  In  the  event  any  Registrable  Securities  are
included in a Registration Statement under this Agreement:

                  (a) To the extent permitted by law, the Company will indemnify
and hold  harmless  the  Investor  who holds such  Registrable  Securities,  any
underwriter (as defined in the Securities Act) for the Investor,  the directors,
if any, of any underwriter and the officers,  if any, of such  underwriter,  and
each person, if any, who controls any such underwriter within the meaning of the
Securities Act or the Exchange Act (each, an "Indemnified Person"),  against any
losses,   claims,   damages,   expenses  or   liabilities   (joint  or  several)
(collectively "Claims") to which any of them become subject under the Securities
Act,  the  Exchange  Act or  otherwise,  insofar as such  Claims (or  actions or
proceedings,  whether commenced or threatened,  in respect thereof) arise out of
or are based upon any of the  following  statements,  omissions or violations in
the Registration  Statement,  or any post-effective  amendment  thereof,  or any
prospectus  included  therein:  (i)  any  untrue  statement  or  alleged  untrue
statement  of a material  fact  contained in the  Registration  Statement or any
post-effective  amendment  thereof or the omission or alleged  omission to state
therein a material fact  required to be stated  therein or necessary to make the
statements  therein not misleading,  (ii) any untrue statement or alleged untrue
statement of a material  fact  contained in any  preliminary  prospectus if used
prior to the effective date of such Registration  Statement, or contained in the
final prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement  thereto with the SEC) or the omission or alleged omission
to state  therein  any  material  fact  necessary  to make the  statements  made
therein,  in light of the circumstances  under which the statements therein were
made, not misleading or (iii) any violation or alleged  violation by the Company
of the Securities Act, the Exchange Act or any state  securities law or any rule
or  regulation  (the matters in the  foregoing  clauses (i) through (iii) being,
collectively,  "Violations").  Subject to the  restrictions set forth in Section
6(d) with respect to the number of legal  counsel,  the Company shall  reimburse
the Investor and each such underwriter or controlling  person,  promptly as such
expenses  are  incurred  and are due and  payable,  for any legal  fees or other
reasonable  expenses  incurred  by  them in  connection  with  investigating  or
defending  any such Claim.  Notwithstanding  anything to the contrary  contained
herein, the  indemnification  agreement contained in this Section 6(a) (I) shall
not apply to a Claim  arising out of or based upon a Violation  which  occurs in
reliance upon and in  conformity  with  information  furnished in writing to the
Company by any  Indemnified  Person or underwriter for such  Indemnified  Person
expressly  for  use in  connection  with  the  preparation  of the  Registration
Statement, preliminary prospectus, final prospectus or any amendments thereof or
supplements thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) hereof; (II) with respect to any preliminary prospectus
shall not inure to the benefit of any such person from whom the person asserting
any such Claim purchased the Registrable Securities that are the subject thereof
(or  to the  benefit  of any  person  controlling  such  person)  if the  untrue
statement or omission of material fact contained in the  preliminary  prospectus
was  corrected  in the  prospectus,  as then  amended or  supplemented,  if such
prospectus  was timely made  available  by the Company  pursuant to Section 3(c)
hereof;  and (III) shall not apply to amounts paid in settlement of any Claim if
such settlement is effected without the prior

                                                         8

<PAGE>



written  consent  of the  Company,  which  consent  shall  not  be  unreasonably
withheld. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Persons.

                  (b) In connection with any Registration Statement in which the
Investor is  participating,  the Investor agrees to indemnify and hold harmless,
to the same  extent  and in the same  manner  set  forth in  Section  6(a),  the
Company, each of its directors,  each of its officers who signs the Registration
Statement,  each person,  if any, who controls the Company within the meaning of
the  Securities  Act  or  the  Exchange  Act,  any  underwriter  and  any  other
stockholder selling securities pursuant to the Registration  Statement of any of
its  directors  or  officers  or any person who  controls  such  stockholder  or
underwriter  within  the  meaning  of the  Securities  Act or the  Exchange  Act
(collectively and together with an Indemnified person, an "Indemnified  Party"),
against any Claims to which any of them may become subject, under the Securities
Act, the Exchange Act or otherwise,  insofar as such Claims(s)  arises out of or
is based  upon any  Violation(s),  in each case to the  extent  (and only to the
extent) that such  Violation(s)  occurs in reliance upon and in conformity  with
written  information  furnished to the Company by the Investor expressly for use
in connection with such Registration  Statement;  and the Investor will promptly
reimburse any legal or other expenses  reasonably incurred by them in connection
with  investigating  or defending any such Claim;  provided,  however,  that the
Investor shall be liable under this Section 6(b) for only that amount of a Claim
as does not exceed the net  proceeds to the  Investor as a result of the sale of
Registrable Securities pursuant to such Registration  Statement.  Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on  behalf of such  Indemnified  Party and shall  survive  the  transfer  of the
Registrable  Securities by the Investor  pursuant to Section 9.  Notwithstanding
anything to the contrary herein, the indemnification agreement contained in this
Section 6(b) with respect to any preliminary  prospectus  shall not inure to the
benefit of any Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary  prospectus was corrected on a timely basis in
the prospectus, as then amended or supplemented.

                  (c) The Company shall be entitled to receive  indemnities from
underwriters,  selling brokers,  dealer managers and similar securities industry
professionals participating in any distribution,  to the same extent as provided
above,  with respect to information such persons so furnished in writing by such
persons expressly for inclusion in the Registration Statement.

                  (d)  Promptly  after  receipt  by  an  Indemnified  Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   such  Indemnified  Person  or
Indemnified Party shall, if a Claim in respect thereof is to be made against any
indemnifying  party under this  Section 6, deliver to the  indemnifying  party a
written notice of the commencement thereof and the indemnifying party shall have
the right to  participate  in,  and,  to the  extent the  indemnifying  party so
desires,  jointly with any other indemnifying party similarly noticed, to assume
control  of the  defense  thereof  with  counsel  mutually  satisfactory  to the
indemnifying parties; provided,

                                                         9

<PAGE>



however, that an Indemnified Person or Indemnified Party shall have the right to
retain  its  own  counsel,  with  the  fees  and  expenses  to be  paid  by  the
indemnifying  party,  if, in the reasonable  opinion of counsel  retained by the
indemnifying party, the representation by such counsel of the Indemnified Person
or Indemnified  Party and the indemnifying  party would be inappropriate  due to
actual or  potential  differing  interests  between such  Indemnified  Person or
Indemnified Party and indemnifying  party in such proceeding.  The Company shall
pay for  only  one  separate  legal  counsel  for  the  Investor  as may  become
Indemnified Parties or Indemnified Persons; such legal counsel shall be selected
by the Investor  holding a majority in interest of the  Registrable  Securities.
The  failure  to  deliver  written  notice to the  indemnifying  party  within a
reasonable  time of the  commencement  of any such action shall not relieve such
indemnifying  party of any liability to the  Indemnified  Person or  Indemnified
Party under this Section 6, except to the extent that the indemnifying  party is
prejudiced in its ability to defend such action. The indemnification required by
this Section 6 shall be made by periodic  payments of the amount  thereof during
the course of the  investigation or defense,  as such expense,  loss,  damage or
liability is incurred and is due and payable.

                  (e) Any Holder  required to indemnify  the Company as provided
in this  Section  6 shall  cease to have the right to  participate  in any other
registration pursuant to this Agreement.

         7. Contribution.  To the extent any indemnification provided for herein
is  prohibited  or limited by law,  the  indemnifying  party  agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable  under  Section  6 to the  fullest  extent  permitted  by law;  provided,
however,  that (a) no contribution shall be made under  circumstances  where the
maker would not have been liable for  indemnification  under the fault standards
set  forth in  Section  6, (b) no  Holder of  Registrable  Securities  guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities Act) shall be entitled to contribution from any Holder of Registrable
Securities  who was not  guilty  of such  fraudulent  misrepresentation  and (c)
contribution by any Holder of Registrable  Securities shall be limited in amount
to the net amount of  proceeds  received  by such  Holder  from the sale of such
Registrable Securities.

         8. Reports under  Exchange Act. With a view to making  available to the
Investor the benefits of Rule 144 or any other similar rule or regulation of the
SEC that may at any time permit the Investor to sell  securities  of the Company
to the public without registration, until such time as the Investor has sold all
the  Registrable  Securities  held by the  Investor  pursuant to a  Registration
Statement or Rule 144 or otherwise, the Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

                                                        10

<PAGE>




                  (c)  furnish  to the  Investor  so long as the  Investor  owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied  with the reporting  requirements  of Rule 144, the
Securities  Act and the Exchange  Act,  (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company and (iii) such other  information as may be reasonably  requested to
permit  the  Investor  to sell  such  securities  pursuant  to Rule 144  without
registration.

        9. Assignment of the Registration Rights. The rights to have the Company
register  Registrable  Securities pursuant to this Agreement may not be assigned
by the Initial Investor without the prior written consent of the Company.

         10. Amendment of Registration  Rights.  Any provision of this Agreement
may be amended and the observance  thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively),  only with the
written  consent  of the  Company  and the  Investor.  Any  amendment  or waiver
effected in  accordance  with this Section 10 shall be binding upon the Investor
and the Company.

         11.      Miscellaneous.

                  (a) A person or entity is deemed to be a holder of Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

                  (b) Notices  required or permitted to be given hereunder shall
be in writing (including facsimile) and shall be deemed to be sufficiently given
and delivered when personally delivered,  faxed (with a copy sent by first class
mail) or when sent by registered mail, return receipt  requested,  addressed (i)
if to the  Company,  at EDITEK,  Inc.,  1238  Anthony  Road,  Burlington,  North
Carolina 27215,  Attention:  Peter J. Heath, Chief Financial Officer, (ii) if to
the Investor,  at the address set forth on the signature  page to this Agreement
and or at such other  address as each such party  furnishes  by notice  given in
accordance  with this Section  11(b),  and shall be effective,  when  personally
delivered,  upon receipt,  when faxed, the day after  transmission,  and when so
sent by certified  mail, four business days after deposit with the United States
Postal Service.

                  (c) Failure of any party to exercise any right or remedy under
this  Agreement,  or otherwise,  or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof.

                  (d)  This  Agreement  shall  be  enforced,   governed  by  and
construed in accordance with the laws of the State of New York applicable to the
agreements made and to

                                                        11

be performed entirely within such state. In the event that any provision of this
Agreement is invalid or  unenforceable  under any applicable  statute or rule of
law, then such provision  shall be deemed  inoperative to the extent that it may
conflict  therewith and shall be deemed modified to conform with such statute or
rule of law. Any provision hereof which may prove invalid or unenforceable under
any law shall not affect the validity or  enforceability  of any other provision
hereof.

                  (e) This Agreement  constitutes the entire agreement among the
parties  hereto  with  respect  to  the  subject  matter  hereof.  There  are no
restrictions,  promises, warranties or undertakings,  other than those set forth
or  referred to herein.  This  Agreement  supersedes  all prior  agreements  and
understandings  among the  parties  hereto with  respect to the  subject  matter
hereof.

                  (f)  Subject to the  requirements  of  Section 9 hereof,  this
Agreement  shall inure to the benefit of and be binding upon the  successors and
assigns of each of the parties hereto.

                  (g) All  pronouns  and any  variations  thereof  refer  to the
masculine, feminine or neuter, singular or plural, as the context may required.

                  (h) The  headings  in the  Agreement  are for  convenience  of
reference only and shall not limit or otherwise affect the meaning hereof.

                  (i)  This   Agreement   may  be   executed   in  two  or  more
counterparts,  each of which shall be deemed an original  but all of which shall
constitute one and the same agreement. This Agreement, once executed by a party,
may be  delivered  to  the  other  party  hereto  by  telephone  line  facsimile
transmission  of a copy of this Agreement  bearing the signature of the party so
delivering this Agreement.


         IN WITNESS  WHEREOF,  the parties have caused this Agreement to be duly
executed by their  respective  officers  thereunto duly authorized as of day and

                                WARRANT AGREEMENT


         WARRANT AGREEMENT (the "Warrant Agreement") is dated as of December 18,
1995 between EDITEK,  INC., a Delaware corporation (the "Company") and Samuel C.
Powell  and his  authorized,  registered  successors  or assigns  (the  "Warrant
Holder").

         Subject to adjustment as hereinafter provided,  the Company proposes to
issue  to  Warrant  Holder  certain  warrants  as  hereinafter   described  (the
"Warrants")  to  purchase up to an  aggregate  of 32,679  shares  (the  "Warrant
Shares") of the Company's  Common  Stock,  par value $.15 per share (the "Common
Stock"),  exercisable at $2.96 per Warrant Share,  and each Warrant entitles the
holder thereof to purchase one share of Common Stock.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
agreements herein set forth and for other good and valuable  consideration,  the
parties hereto agree as follows:

         1. Issuance of Warrants;  Form of Warrant. The Company will issue, sell
and deliver  the  Warrant  Certificate  evidencing  the  Warrants to the Warrant
Holder  or at its  direction,  to its bona  fide  officers  and  directors  upon
execution  of  this  Warrant  Agreement.  The  text of the  Warrant  Certificate
(hereinafter referred to as "Warrant" or "Warrant  Certificate") and the form of
election to purchase shares to be attached thereto shall be substantially as set
forth in Exhibit A attached hereto.  The Warrants shall be executed on behalf of
the Company by the manual or  facsimile  signature  of the present or any future
President or Vice President of the Company, under its corporate seal, affixed or
in  facsimile,  attested by the manual or facsimile  signature of the present or
any future Secretary or Assistant Secretary of the Company.

         2.  Registered  Form.  The Warrants  shall be  registered  in a Warrant
register  as they are  issued.  The  Company  shall  be  entitled  to treat  the
registered  holder (the "Warrant Holder") of any Warrant on the Warrant register
as the  owner  in fact  thereof  for all  purposes  and  shall  not be  bound to
recognize  any  equitable  or other claim to or interest in such  Warrant on the
part of any other person. The Warrants shall be registered initially in the name
of Samuel C. Powell.

         3. Transfer of Warrants.  The Warrants and the Warrant  Shares will not
be  transferable,  in  part or in  whole,  except  (i) in  compliance  with  the
Securities  Act of 1933, as amended (the "Act"),  and the rules and  regulations
promulgated  thereunder,  and any applicable state securities laws and (ii) only
on the books of the Company upon  delivery  thereof duly endorsed by the Warrant
Holder or by its duly authorized  attorney or representative,  or accompanied by
proper evidence of succession, assignment or authority to transfer. In all cases
of transfer by an attorney, the original power of attorney, duly approved, or an
official copy thereof,  duly certified,  shall be deposited with the Company. In
case  of  transfer  by  executors,  administrators,  guardians  or  other  legal
representatives, duly


<PAGE>



authenticated evidence of their authority shall be produced, and may be required
to be deposited with the Company in its  discretion.  Upon any  registration  of
transfer,  the  Company  shall  deliver a new Warrant or Warrants to the persons
entitled  thereto.  The  Warrants  may be  exchanged  at the  option of the then
Warrant  Holder  thereof,  for another  Warrant,  or other Warrants of different
denominations,  of like tenor and  representing  in the  aggregate  the right to
purchase a like number of Warrant  Shares upon  surrender  to the Company or its
duly authorized agent.  Notwithstanding the foregoing, the Company shall have no
obligation  to cause  Warrants  to be  transferred  on its books to any  person,
unless  the  Warrant  Holder or Warrant  Holders  thereof  shall  furnish to the
Company evidence of compliance with the Act in accordance with the provisions of
Section 10 of this Agreement.

         4. Term of Warrants;  Exercise of Warrants.  Each Warrant  entitles the
Warrant Holder thereof to purchase one share of Common Stock at a purchase price
of $2.96 per share (the  "Exercise  Price") at any time after  December 18, 1995
(the  "Effective  Date") until 5:00 p.m.,  New York City time, on March 17, 1999
(the  "Expiration  Date").  The Exercise  Price and the number of Warrant Shares
issuable  upon  exercise  of the  Warrants  are subject to  adjustment  upon the
occurrence of certain  events,  pursuant to the  provisions of Section 8 of this
Agreement.  Subject to the  provisions of this  Agreement,  each Warrant  Holder
shall have the right,  which may be exercised as set forth in such Warrants,  to
purchase  from the Company (and the Company shall issue and sell to such Warrant
Holder)  the  number of fully  paid and  nonassessable  shares  of Common  Stock
specified in such Warrant, upon surrender to the Company, or its duly authorized
agent of such Warrants,  with the form of election to purchase  attached thereto
duly  completed  and signed,  with  signatures  guaranteed by a member firm of a
national securities  exchange,  a commercial bank (not a savings bank or savings
and loan  association) or trust company located in the United States or a member
of the NASD, and upon payment to the Company of the Exercise  Price, as adjusted
(if  applicable) in accordance  with  provisions of Section 8 of this Agreement,
times the number of Warrant  Shares in respect of which such  Warrants  are then
exercised.  Payment  of such  Exercise  Price  may be  made in cash or by  check
payable  to the  order  of the  Company.  No  adjustment  shall  be made for any
dividends on any shares of stock issuable upon exercise of a Warrant.  Upon each
surrender  of  Warrants  and payment of the  Exercise  Price as  aforesaid,  the
Company shall issue and cause to be delivered with all reasonable dispatch to or
upon the written  order of the Warrant  Holder of such  Warrants and (subject to
receipt of evidence of compliance with the Act in accordance with the provisions
of Section 10 of this  Agreement)  in such name or names as such Warrant  Holder
may  designate,  a certificate  or  certificates  for the number of full Warrant
Shares so purchased upon the exercise of such  Warrants,  together with cash, as
provided in Section 9 of this  Agreement,  in respect of any fractional  Warrant
Shares otherwise issuable upon such surrender.  Such certificate or certificates
shall be deemed to have been  issued  and any person so  designated  to be named
therein shall be deemed to have become a holder of record of such Warrant Shares
as of the date of the surrender of Warrants and payment of the Exercise Price as
aforesaid; provided, however, that if, at the date of surrender of such Warrants
and payment of such Exercise  Price,  the transfer books for the Common Stock or
other class of stock  purchasable  upon the exercise of such  Warrants  shall be
issuable, shall be closed, the certificates for the shares

                                                         2

shall be issuable as of the date on which such books are reopened and until such
time the  Company  shall be under no duty to deliver  any  certificate  for such
Warrant Shares;  provided,  further,  that the transfer books,  unless otherwise
required by law, shall not be closed at any one time for a period longer than 20
days. The rights of purchase  represented by the Warrants shall be  exercisable,
at the election of the Warrant Holders  thereof,  either in full or from time to
time in part and, in the event that any Warrant is  exercised in respect of less
than all of the Warrant Shares purchasable on such exercise at any time prior to
the Expiration  Date, a new Warrant or Warrants will be issued for the remaining
number of Warrant Shares specified in the Warrant so surrendered.

         5. Payment of Taxes. The Company will pay all documentary  stamp taxes,
if any,  attributable  to the  issuance of Warrant  Shares upon the  exercise of
Warrants;  provided,  however, that the Company shall not be required to pay any
tax or taxes  which may be payable in respect of any  transfer  involved  in the
issue or delivery of any certificates for Warrant Shares,  and the Company shall
not be required  to issue or deliver any  certificate  for such  Warrant  Shares
until the person  requesting the same has paid to the Company the amount of such
tax or has  established  to the  Company's  satisfaction  that such tax has been
paid.

         6. Mutilated or Missing Warrants.  In case any of the Warrants shall be
mutilated, lost, stolen or destroyed, the Company may, in its discretion,  issue
and  deliver in  exchange  and  substitution  for and upon  cancellation  of the
mutilated  Warrant,  or in lieu of and substitution for the Warrant lost, stolen
or  destroyed,  a new  Warrant  for the number of  Warrants  represented  by the
Warrant  so  mutilated,  lost,  stolen or  destroyed  but only upon  receipt  of
sufficient evidence of such loss, theft or destruction of such Warrant,  and the
ownership thereof,  and an agreement to indemnify the Company, if required,  all
satisfactory to the Company.  An applicant for such substitute Warrants shall so
comply  with such other  reasonable  regulations  and pay such other  reasonable
charges incidental thereto as the Company may prescribe.

         7.  Reservation of Warrant Shares,  etc. The Company shall at all times
after the  Effective  Date keep  reserved,  out of the  authorized  and unissued
Common Stock,  a number of shares of Common Stock  sufficient to provide for the
exercise  of the rights of purchase  represented  by the  outstanding  Warrants.
American  Stock  Transfer & Trust  Company,  transfer agent for the Common Stock
(the "Transfer Agent"),  and every subsequent transfer agent, if any, for shares
of the Company's  capital stock  issuable upon the exercise of any of the rights
of purchase aforesaid,  will be irrevocably authorized and directed at all times
until the  Expiration  Date to reserve  such number of  authorized  and unissued
shares as shall be required for such purpose. The Company will itself provide or
otherwise  make  available  any cash which may be  distributable  as provided in
Section 9 of this  Agreement.  All Warrants  surrendered  in the exercise of the
rights thereby  evidenced  shall be canceled,  and such canceled  Warrants shall
constitute sufficient evidence of the number of shares of Common Stock that have
been issued upon the exercise of such Warrants. No shares of Common

                                                         3

<PAGE>



Stock  shall be  subject to  reservation  in  respect  of  unexercised  Warrants
subsequent to the Expiration Date.

         8.  Adjustments  of Exercise  Price and Number of Warrant  Shares.  The
Exercise Price and the number and kind of securities  purchasable  upon exercise
of each  Warrant  shall be  subject  to  adjustment  from  time to time upon the
happening of certain events, as follows:

                  (a) In case the  Company  shall (i)  declare a dividend on its
Common  Stock in  shares  of Common  Stock or make a  distribution  in shares of
Common  Stock,  (ii)  subdivide  its  outstanding  shares of Common Stock into a
greater number of shares,  (iii) combine its outstanding  shares of Common Stock
into  a  smaller   number  of   shares  of  Common   Stock  or  (iv)   issue  by
reclassification  of its shares of Common Stock other  securities of the Company
(including  any such  reclassification  in connection  with a  consolidation  or
merger  in which the  Company  is the  continuing  corporation),  the  number of
Warrants Shares  purchasable upon exercise of each Warrant  immediately prior to
the record or  effective  date  therefor  shall be  adjusted so that the Warrant
Holder of each  Warrant  shall be  entitled  to  receive  the kind and number of
Warrant  Shares or other  securities  of the Company  which such Warrant  Holder
would have owned or have been  entitled to receive after the happening of any of
the events described above, had such Warrant been exercised immediately prior to
the  happening  of such  event or any  record  date  with  respect  thereto.  An
adjustment   made  pursuant  to  this  paragraph  (a)  shall  become   effective
immediately  after the effective  date of such event  retroactive to immediately
after the record date, if any, for such event.

                  (b) Whenever the number of Warrant Shares purchasable upon the
exercise of each Warrant is adjusted,  as herein  provided,  the Exercise  Price
shall adjusted by  multiplying  such exercise  Price  immediately  prior to such
adjustment  by a fraction,  the numerator of which shall be the number of shares
purchasable  upon  the  exercise  of  each  Warrant  immediately  prior  to such
adjustment,  and the  denominator of which shall be the number of Warrant Shares
so purchasable immediately thereafter.

                  (c) For the  purpose of this  Section  8, the term  "shares of
Common  Stock" shall mean (i) the class of stock  designated as the Common Stock
of the  Company at the date of this  Agreement  or (ii) any other class of stock
resulting from successive changes or  reclassification of such shares consisting
solely of changes in par  value,  or from par value to no par value,  or from no
par  value to par  value.  In the  event  that at any  time,  as a result  of an
adjustment  made  pursuant to paragraph  (a) above,  the Warrant  Holders  shall
become  entitled to purchase  any shares of capital  stock of the Company  other
than  shares of Common  Stock,  thereafter  the number of such  other  shares so
purchasable  upon exercise of each Warrant and the Exercise Price of such shares
shall be  subject  to  adjustment  from time to time in a manner and on terms as
nearly  equivalent as practicable to the provisions  with respect to the Warrant
Shares contained in paragraphs (a) through (b), inclusive, above, and paragraphs
(d) through (f), inclusive, of this Section 8, and the provisions of Sections 4,
5, 7 and 12, with  respect to the Warrant  Shares,  shall apply on like terms to
any such other shares.

                                                         4

<PAGE>




                  (d) The Company may at its option, at any time during the term
of the  Warrants,  reduce the then current  Exercise  Price to any amount deemed
appropriate by the Board of Directors of the Company; provided, however, that in
no event shall the Exercise  Price be adjusted  below the par value per share of
the Common Stock.

                  (e) In case of any consolidation or merger of the Company with
or into  another  corporation  r in case of any sale or  conveyance  to  another
corporation of the property of the Company as an entirety or substantially as an
entirety,  the  Company  or such  successor  or  purchasing  corporation  (or an
affiliate of such  successor  or  purchasing  corporation),  as the case may be,
agrees  that such  Warrant  Holder  shall  have the right for  thirty  (30) days
thereafter  upon payment of the Exercise  Price in effect  immediately  prior to
such action to  purchase  upon  exercise of each  Warrant the kind and amount of
shares and other  securities and property  (including  cash) which he would have
owned  or  have  been   entitled  to  receive   after  the   happening  of  such
consolidation,  merger,  sale or  conveyance  had such  Warrant  been  exercised
immediately  prior to such action.  The  provisions of this  paragraph (e) shall
similarly apply to successive consolidations, mergers, sales or conveyances.

                  (f)  Notwithstanding  any adjustments in the Exercise Price or
the  number or kind of shares  purchasable  upon the  exercise  of the  Warrants
pursuant to this Agreement, certificates for Warrants issued prior or subsequent
to such  adjustments many continue to express the same price and number and kind
of shares as are stated in the  Warrants  initially  issuable  pursuant  to this
Agreement.

         9.  Fractional  Interests.  The Company  shall not be required to issue
fractions of shares of Common  Stock on the  exercise of Warrants.  If more than
one Warrant shall be presented for exercise in full at the same time by the same
Warrant  Holder,  the number of Warrant  Shares which shall be issuable upon the
exercise  thereof  shall be  computed  on the basis of the  aggregate  number of
Warrant  Shares  purchasable  on exercise of the Warrants so  presented.  If any
fraction of a share of Common Stock  would,  except for the  provisions  of this
Section 9, be issuable on the  exercise  of any Warrant (or  specified  portions
thereof),  the Company shall  purchase such fraction for an amount in cash equal
to the same  fraction of the current  market  price per share of Common Stock on
the date of exercise  which  price  shall be the last sale price,  or in case no
sale takes place on such day, the average of the closing bid and asked prices on
the  principal  national  securities  exchange on which the Common  Stock of the
Company is traded, or if not traded on any national  exchange,  then the average
of the closing bid and asked  prices as quoted on the  National  Association  of
Securities  Dealers Automated  Quotation System ("NASDAQ") or as reported by the
National Quotation Bureau, Inc. or similar reporting organization.

         10.  Restriction on  Dispositions.  The Warrants and the Warrant Shares
have not been  registered  under the Act.  The  Warrant  Holder  represents  and
warrants to the Company  that it  understands  that neither the Warrants nor the
Warrant  Shares  may  be  transferred   except  pursuant  to  (i)  an  effective
Registration Statement under the Act, or (ii) any available
                                                         5

<PAGE>



rule or exemption from registration under the Act permitting such disposition of
securities and an opinion of counsel, reasonably satisfactory to counsel for the
Company, that an exemption from such registration is available.

         11.  Certificates  to Bear Legends.  The Warrants shall be subject to a
stop-transfer order and the certificate or certificates  therefor shall bear the
following legend:

         NEITHER THE WARRANTS REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES
         ISSUABLE UPON EXERCISE HEREOF MAY BE OFFERED OR SOLD EXCEPT PURSUANT TO
         (i) AN EFFECTIVE  REGISTRATION  STATEMENT  UNDER THE  SECURITIES ACT OF
         1933 OR (ii) ANY AVAILABLE  RULE OR EXEMPTION FROM  REGISTRATION  UNDER
         SUCH ACT RELATING TO THE  DISPOSITION  OF SECURITIES  AND AN OPINION OF
         COUNSEL,  REASONABLY  SATISFACTORY TO COUNSEL FOR THIS COMPANY, THAT AN
         EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.

         The Warrant  Shares or other  securities  issued  upon  exercise of the
Warrants  shall be  subject  to a  stop-transfer  order and the  certificate  or
certificates  evidencing  any such  Warrant  Shares or  securities  shall bear a
legend in substantially the following legend:

         THE SHARES  REPRESENTED BY THIS  CERTIFICATE MAY NOT BE OFFERED OR SOLD
         EXCEPT  PURSUANT TO (i) AN EFFECTIVE  REGISTRATION  STATEMENT UNDER THE
         SECURITIES  ACT OF 1933 OR (ii) ANY  AVAILABLE  RULE OR EXEMPTION  FROM
         REGISTRATION  UNDER SUCH ACT RELATING TO THE  DISPOSITION OF SECURITIES
         AND AN OPINION OF COUNSEL,  REASONABLY SATISFACTORY TO COUNSEL FOR THIS
         COMPANY,  THAT  AN  EXEMPTION  FROM  REGISTRATION  UNDER  SUCH  ACT  IS
         AVAILABLE.

         12.  Representations  and Warranties of Warrant  Holder.  In connection
with the issuance of the Warrants,  the Warrant Holder represents to the Company
by acceptance of the Warrants as follows:

                  (a) The  Warrant  Holder  is aware of the  Company's  business
affairs and financial condition,  and has acquired information about the Company
sufficient  to reach an  informed  and  knowledgeable  decision  to acquire  the
Warrants.  The Warrant  Holder is acquiring the Warrants for its own account for
investment  purposes  only and not with view to, or for the resale in connection
with, any "distribution" thereof in violation of the Act.

                  (b) The  Warrant  Holder  understands  that the  Warrants  and
Warrant  Shares  have not  been  registered  under  the Act in  reliance  upon a
specific exemption therefrom,  which exemption depends upon, among other things,
the bona fide  nature of the Warrant  Holder's  investment  intent as  expressed
herein.

                                                         6

<PAGE>




                  (c) The Warrant Holder further  understands  that the Warrants
and  any  Warrant  Shares  to be  issued  upon  exercise  hereof  must  be  held
indefinitely unless subsequently  registered under the Act and either registered
or qualified under any applicable state  securities  laws, or unless  exemptions
from such registration and qualification are otherwise available.

                  (d) The Warrant  Holder agrees that it will not dispose of any
of  the  Warrants  or  Warrant  Shares  except  pursuant  to  (i)  an  effective
registration  statement under the Act (and, in such case, in compliance with all
prospectus  delivery or other requirements to sell pursuant to such registration
statement),  (ii)  Rule 144  under the Act (or any  similar  rule  under the Act
relating to the  disposition  of securities) or (iii) an opinion of counsel that
an exemption from registration is available.

         13.  Registration  Rights.  The Company hereby  covenants and agrees to
grant  certain  registration  rights to the Warrant  Holder with  respect to the
Warrant Shares, as follows:

                  (a) If the Company proposes to register any of its securities,
either for its own account or the  account of others,  solely for cash under the
Securities Act of 1933, as amended (the  "Securities  Act"),  either for its own
account or the account of others  (other than any  registration  effected by the
Company to implement an employee benefit plan or for a transaction to which Rule
145 or any similar rule under the  Securities Act is  applicable),  it will give
written notice to the Warrant Holder of its intention to do so. Upon the written
request of the Warrant Holder received by the Company within ten (10) days after
the date of any such notice  (which  request shall specify the amount of Warrant
Shares  intended to be disposed of by the Warrant Holder and the intended method
of  disposition  thereof),  the Company  will use its best efforts to effect the
registration,   in  a  registration  statement  (the  "Registration  Statement")
covering the securities to be offered by the Company,  of the  securities  which
the Company has been so  requested  to register by the Warrant  Holder and other
security holders;  provided, that if, at any time after giving written notice of
its intention to register any  securities and prior to the effective date of the
Registration  Statement,  the  Company  shall  determine  for any  reason not to
register or to delay  registration of such  securities,  the Company may, at its
election,  give  written  notice  of such  determination  to each  holder  whose
securities are to be included in the Registration Statement and, thereupon,  (i)
in the  case of a  determination  not to  register,  shall  be  relieved  of its
obligation to register any securities in connection with such registration,  and
(ii) in the case of a determination to delay registering,  shall be permitted to
delay registering any securities for the same period as the delay in registering
such other  securities;  provided  further,  that in the case of an underwritten
registration, the Company shall not be required to register securities in excess
of the amount,  if any, which the principal  underwriter shall reasonably and in
good faith agree in writing to include in such registration.  Any Warrant Shares
and any securities of any other security holder who holds  securities  requested
to be included in such registration which are not included for this reason shall
be included  (subject,  first,  to the inclusion of all  securities  the Company
proposes to register and sell, if any) on a pro rata

                                                         7

<PAGE>



basis in proportion  to the  respective  holdings of securities  requested to be
included in such registration.  The Warrant Holder shall be entitled to exercise
the  registration   rights  described  herein  only  once;   provided  that  the
Registration  Statement  becomes and remains  effective for at least ninety (90)
days.  The  Company  shall  pay  its  own  expenses  in  connection   with  such
registration;  the Warrant Holder shall pay all fees and expenses of the Warrant
Holder's  own  counsel  and the  Warrant  Holder's  proportionate  share  of all
registration  and  qualification  fees  and  expenses  (including  underwriters'
discounts and  commissions) and other expenses that result from the inclusion of
the Warrant  Shares in such  registration.  The Warrant Holder shall provide the
Company in a signed writing such information  about the Warrant Holder as in the
opinion  of  securities  counsel to the  Company  shall be either  necessary  or
reasonably  appropriate  to enable the Company to comply with the Securities Act
and applicable state securities laws.

         (b) The  Company  shall use its best  efforts to  register,  qualify or
obtain  exemption from  registration  or  qualification  for, the Warrant Shares
covered by the  Registration  Statement under such other  securities or blue sky
laws of such jurisdictions as the Company  determines to register  securities to
be sold by the Company.

         (c)  Notwithstanding  the  foregoing,  the  Company  (i)  shall  not be
obligated to register  Warrant  Shares held by the Warrant Holder if the Company
shall furnish the Warrant  Holder with a written  opinion of counsel  reasonably
satisfactory  to the  Warrant  Holder,  that the  Warrant  Shares  sought  to be
registered may be publicly offered,  sold and distributed  without  registration
under the  Securities  Act  pursuant to Rule 144 without  restriction  as to the
amount  of  securities  that can be sold;  and (ii) if the  registration  herein
described is an underwritten offering,  shall have no obligation to register the
Warrant  Holder's  Warrant  Shares,  unless the  Warrant  Holder  enters into an
underwriting  agreement in customary form with the  underwriter or  underwriters
selected for the offering by the Company,  and enters into such other agreements
(including,  but not limited to, holdback or lock-up  agreements and a customary
and  reasonable  agreement to  indemnify  the Company and any  underwriter)  and
provides  such  documents  as are  customary  and  reasonable  for  underwritten
offerings.

         14. Notices to Warrant Holders.  Nothing contained in this Agreement or
in any of the Warrants shall be construed as conferring upon the Warrant Holders
thereof  the right to vote or to receive  dividends  or to consent or to receive
notice as  stockholders  in  respect  of the  meetings  of  stockholders  or the
election  of  directors  of the  Company  or any  other  matter,  or any  rights
whatsoever as stockholders of the Company; provided,  however, that in the event
a meeting of the  stockholders  shall be called to consider and take action on a
proposal for the voluntary dissolution of the Company,  other than in connection
with a consolidation,  merger,  sale or transfer of all of substantially  all of
its assets,  business and good will as an  entirety,  then and in that event the
Company shall cause a notice  thereof to be sent by  first-class  mail,  postage
prepaid,  at least 10 days prior to the date fixed as a record  date or the date
of closing the transfer  books in relation to such meeting,  to each  registered
Warrant  Holder of Warrants at such Warrant  Holder's  address  appearing on the
Warrant register; but

                                                         8

<PAGE>



failure  to mail or to  receive  such  notice or any  defect  therein  or in the
mailing  thereof shall not affect the validity of any action taken in connection
with such voluntary dissolution.  If such notice shall have been so given and if
such  voluntary   dissolution  shall  be  authorized  at  such  meeting  or  any
adjournment  thereof,  then  from and  after  the date on which  such  voluntary
dissolution  shall have been duly authorized by the  shareholders,  the Warrants
and all other rights with respect thereto shall cease and terminate.

         15. Notices.  Any notice pursuant to this Agreement to be given or made
to the Company by the Warrant Holder of any Warrants shall be sufficiently given
or made if sent by first-class mail, postage prepaid, addressed as follows:

         Notices or demands  authorized by this Agreement to be given or made by
the Company to the Warrant Holder and/or  Warrant  Shares shall be  sufficiently

first-class  mail,  postage  prepaid,  addressed to such  Warrant  Holder at the
address of such Warrant Holder as shown on the Warrant register.

         16.  Governing  Law. This  Agreement and the Warrant  issued  hereunder
shall be governed by and construed in accordance  with the  substantive  laws of
the State of Delaware.

         17.  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts,  each of which so executed shall be deemed to be an original;  but
such counterparts together shall constitute but one and the same instrument.

                       Independent Auditors' Report

The Board of Directors and Stockholders
Medtox Laboratories, Inc.:

We have audited the accompanying consolidated balance sheet of Medtox 
Laboratories, Inc. and subsidiary as of December 31, 1994, and the related 
consolidated statements of operations, stockholders' equity and cash flows 
for each of the years in the two-year period ended December 31, 1994. These 
consolidated financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these consolidated 
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial 
statement presentation. We believe that our audits provide a reasonable basis 
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Medtox Laboratories,
Inc. and subsidiary as of December 31, 1994 and the results of their operations
and their cash flows for each of the years in the two-year period ended 
December 31, 1994 in conformity with generally accepted accounting principles.
