ITEM 1.  BUSINESS.

         1.       General.

     MEDTOX Scientific,  Inc. (formerly EDITEK,  Inc.), a Delaware  corporation,
was  organized in  September,  1986 to succeed the  operations  of a predecessor
California  corporation.  MEDTOX Scientific,  Inc. and its subsidiaries,  MEDTOX
Laboratories,  Inc. and MEDTOX Diagnostics, Inc., are referred to herein as "the
Company".  MEDTOX Laboratories,  Inc. is a toxicology  laboratory which provides
forensic  toxicology,  clinical  toxicology,  and heavy metals analyses.  MEDTOX
Diagnostics,  Inc.  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 is continuing to transition these
operating  units from being  providers  of high  quality  testing  services  and
devices into a broader service organization by supporting  underlying laboratory
analysis and point-of-care  devices with logistics  management,  data management
and overall program management services.

                  The Company  entered the  laboratory  business on February 11,
1994 when it completed the acquisition of Princeton  Diagnostic  Laboratories of
America, Inc. ("PDLA"). On January 30, 1996, the Company acquired the assets and
certain  liabilities of the  predecessor  of MEDTOX  Laboratories,  Inc.  MEDTOX
Laboratories,  Inc. is now a wholly owned subsidiary.  For the fiscal year ended
December 31,  1998,  sales from  laboratory  services  accounted  for 92% of the
Company's  revenues.  Revenue from the sale of the Company's on-site  diagnostic
and  screening  tests  and  other  products,  including  contract  manufacturing
services,  accounted  for 8% of the total  revenues  of the Company for the year
ended December 31, 1998.

         2.       Principal Services, Products, and Markets.

     General. The Company has two reportable  segments:  laboratory services and
products  sales.  Laboratory  services  include  forensic  toxicology,  clinical
toxicology,  and heavy metal  analyses as well as logistics,  data,  and overall
program management services.  Manufactured products include a variety of on-site
screening products.

         Laboratory Services

                   A. Employment Drug Testing Laboratory  Services.  The primary
source of  revenues  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 various immunoassays, gas liquid chromatography, and
gas chromatography/mass  spectrometry.  MEDTOX Laboratories, Inc. was one of the
charter  laboratories  to be  certified  by the  federal  government  to perform
mandated drug testing on regulated employees. It pioneered security and chain of
custody  procedures,  including  sample  bar  coding  as well as  stereospecific
confirmation  methods that assist in maintaining  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 drug  treatment
counseling centers,  occupational health clinics, third party administrators and
hospitals.

<PAGE>

                  B.  Clinical  Toxicology.  The Company  has a fully  certified
clinical toxicology  reference  laboratory  specializing in esoteric therapeutic
drug  monitoring and emergency  toxicology.  The tests performed in the clinical
laboratory are conducted using methodologies such as various  immunoassays,  gas
liquid   chromatography,    high   performance   liquid   chromatography,    gas
chromatography/mass  spectrometry  and tandem  mass  spectrometry.  The  Company
performs  the  analyses  of  many   classes  of  drugs   including:   analgesic,
antianxiety,  anticholinergic,  anticoagulant,  anticonvulsant,  antidepressant,
antidiabetic,   antiemetic,  antihistamine,   antiinflammatory,   antimicrobial,
antipsychotic,   bronchodilator,    cardiovascular,   stimulant,   decongestant,
immunosuppressant,  local anesthetic,  muscle relaxant,  narcotic analgesic, and
sedative medications.

                  The  Company's  clients for this market  consist of hospitals,
clinics and other  laboratories.  Laboratory  specimens  are delivered to MEDTOX
from clients  across the country both by the Company's own couriers,  contracted
delivery services and commercial overnight couriers.

                  C. Heavy  metal,  trace  element,  and solvent  analyses.  The
Company operates a laboratory in which blood and urine are tested for heavy
metals,  trace  elements,  and  solvents.  The  tests  are  performed  using the
methodologies such as Flame and Flameless Atomic Absorption, Inductively Coupled
Plasma-Mass Spectrometry, and Gas Chromatography.

                  The Company's clients for this market are other  laboratories,
occupational  health  clinics  and  companies  which  need to test  patients  or
employees monitored for excess exposure to hazardous materials.

                  D.  Logistics,  Data,  and Program  Management  Services.  The
Company  also  provides  services  in the areas of  logistics  management,  data
management,  and  program  management.  These  services  support  the  Company's
underlying  business  of  laboratory  analysis  and  provide  added value to its
clients.  Value-added services  include  courier  services for medical  specimen
transportation,  management  programs for on-site drug testing,  data collection
and reporting  services,  coordination of specimen collection sites, and medical
surveillance program management.


         Product Sales

                  The  Company's  test  products  are easy to use,  inexpensive,
point-of-care 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.

                  In 1998,  the Company  received  FDA 510(k)  clearance  on the
first  of  its   second-generation   on-  site  test  products,   PROFILE(R)-II.
PROFILE(R)-II,  is  a  five-drug  lateral  flow  device  for  the  detection  of
drugs-of-abuse  in human urine. This  single-step,  immunoassay  device has been
combined with the company's  Data Delivery  System and  laboratory  confirmation
capability to produce the  PROFILE(R)-II  Test System.  This integrated  on-site
testing  system is currently  being  marketed to  occupational  health  clinics,
corporate  clients,  third party  administrators, and drug abuse  counseling and
treatment centers.

                  In   addition   to   the    PROFILE(R)-II,    the    Company's
second-generation products also include VERDICT(R)-II on-site screening devices.
VERDICT(R)-II   products   are   manufactured   in  one,   two  and  three  drug
configurations.  Target markets  include  criminal  justice,  temporary  service
companies, the construction industry and drug rehabilitation facilities.

<PAGE>

     The Company  continues to market the  EZ-SCREEN(R)  tests.  These tests are
qualitative assays utilized in agricultural diagnostics to detect mycotoxins and
antibiotic  residues.  Mycotoxins  are hazardous  substances  produced by fungal
growth and 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.

                  The Company  distributes  on-site  tests for the  detection of
alcohol with the EZ-SCREEN(R)  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 the Breath Alcohol Test through a distribution 
agreement.

                  3.       Marketing and Sales.

                  The  Company  believes  that the  combined  operations  of the
laboratory  services 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 and
occupational medicine marketplace, including (1) on-site tests for the detection
of  substance  of  abuse  drugs  (2)  on-site   qualitative   and   quantitative
determination of alcohol intoxication (both disposable and electronic instrument
detection  devices);  (3) SAMHSA  certified  laboratory  testing  (screening and
confirmation);   (4)  biological   monitoring  of   occupational   toxins;   (5)
consultation; and (6) logistic, data management and program management services.

     The Company  currently  markets these products and all laboratory  services
through  its   dedicated   sales   force,   through   independent   third  party
administrators and through occupational health clinics.

                  Major  Customers.  The  Company had no single  customer  whose
sales  amounted  to more than 10% of its total  revenues  during  the year ended
December 31, 1998. One  customer's  sales  amounted to  approximately  7% of the
revenues  of  MEDTOX  Laboratories,  Inc.  while  sales  to  the  United  States
government  and  its  agencies,   primarily  the  United  States  Department  of
Agriculture  ("USDA"),  amounted to approximately 4% of the revenues from MEDTOX
Diagnostics, Inc.

                  4.       New Products, Research and Development.

     Product  Sales.  Primary  research and  development  efforts of the Company
during 1998 focused on the development of tests to extend the product  offerings
in  the  single-step  Profile(R)-II  immunochromatographic  assay  product  line
produced by the Company.  These product line  extensions  include  Verdict(R)-II
intended  for the criminal  justice  market and  Profile(R)-ER  intended for the
emergency room market.

                  Verdict(R)-II  consists of a line of simplified  Profile(R)-II
devices  designed  to test for the drugs  that the  criminal  justice  system is
primarily  concerned  with today.  MEDTOX has begun to market the  Verdict(R)-II
tests, with good acceptance, to distributors in this market. Profile(R)-ER is an
expanded product which tests for additional  drugs,  compared to  Profile(R)-II.
The added drugs are especially  pertinent in the rule-out diagnosis of suspected
toxic drugs in emergency room settings. MEDTOX hopes to submit Profile(R)-ER for
FDA-clearance at the end of the second quarter 1999.

     Laboratory  Services.  The research and  development  department  of MEDTOX
Laboratories develops new assays for new drug entities,  develops new assays for
existing  metabolites of drugs and other toxins,  and improves  existing  assays
with the goals of  improving  the  assays'  robustness,  sensitivity,  accuracy,
precision,  specificity,  and cost.  Numerous new  laboratory-based  assays were
developed during 1998 using immunochemistry, liquid chromatography (LC), gas

<PAGE>

chromatography (GC), gas chromatography with mass spectrometry  (GC/MS),  atomic
absorption (AA),  inductively  coupled plasma mass  spectrometry  (ICP/MS),  and
tandem  mass   spectrometry   (LC/MS/MS).   During  1999  we  plan  to  add  gas
chromatography  with tandem mass  spectrometry  (GC/MS/MS) as well. The many new
tests developed  during 1998 expand our  capabilities in the esoteric  reference
clinical  toxicology market (providing  sophisticated  testing for hospitals and
other reference  laboratories),  expand our capabilities and laboratory services
in biological monitoring of toxins in the workplace,  expand our capabilities of
detecting  drugs of abuse for clinical and workplace  analysis,  and also expand
our  capabilities  in  pharmaceutical  research  analysis.  During 1998,  MEDTOX
developed a medical diagnostic  laboratory to service multi-site clinical trials
for the  pharmaceutical  industry  and  also  provide  broader  services  to our
industrial toxicology and occupational  medicine clients.  Business generated by
these expanded  laboratory  services to industrial  clients is already  becoming
significant,  while  we have  also  received  initial  contracts  for  servicing
clinical trials.  Significant  developmental  progress was also made during 1998
for our new line of nutritional assays which include analysis of vitamins, amino
acids,  trace  elements,  measures of oxidative  stress,  and activities of free
radical scavenging enzymes.  This work allows us to assess an individual's level
of oxidative  stress,  their  ability to overcome  that  oxidative  stress,  any
nutritional  deficiencies,  and monitor supplementation to improve their ability
to overcome that stress.  This area of testing is being shown to be important in
the detection of susceptibility to cancers, cardiac diseases, dementias, macular
degeneration,  and is related to the  development of serious  adverse effects of
drugs.
         5.       Raw Materials.

                  Laboratory  Services.   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.

                  Product  Sales.  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 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.

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

     Product  Sales.  The  Company  has a patent  pending on the system  that it
developed which integrates  on-site  scientific  analysis with  state-of-the-art
data  collection and delivery.  The system is currently  being utilized with the
Company's PROFILE(R)-II and Verdict(R)-II products.

                  The Company holds nine issued United States  patents  relating
to on-site testing  technology.  Eight of these patents generally form the basis
for the EZ-SCREEN and one-step  technologies  while the other patent  relates to
methods of utilizing whole blood as a sample medium on its immunoassay devices.

                  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.
<PAGE>

                  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.

     Laboratory  Services.  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.

     General.  The Company holds  approximately 15 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.

         7.       Seasonality.

                  Laboratory Services.  The Company believes that the laboratory
testing  business  is  subject  to  seasonal   fluctuations  in   pre-employment
screening.  These  seasonal  fluctuations  include  reduced volume in the summer
months,  year-end  holiday  periods,  and other  major  holidays.  In  addition,
inclement  weather may have a negative  impact on volume  thereby  reducing  net
revenues and cash flow.

     Product  Sales.  The  Company  does  not  believe  that  seasonality  is  a
significant factor in sales of its on-site immunoassay tests.

         8.       Backlog.

                  Laboratory  Services.  There exists a delay in  recognition of
revenues  when setting up new accounts for  laboratory  services.  The time from
when an  account  becomes a client  of the  Company  to the time the  laboratory
starts  receiving  specimens  may be up to four  months.  The delay in receiving
samples  is  primarily  due  to  the  necessity  of  establishing  communication
capabilities between the client and the laboratory,  the requirement to ship out
collection kits and forms,  and the  establishment of a collection site network.
At December 31, 1998,  the Company did have several  accounts  which were in the
process of being set up where revenues are expected to be realized in 1999.

     Product Sales. At December 31, 1998, MEDTOX Diagnostics,  Inc. did not have
any significant backlog and normally does not have any significant  backlog. The
Company  does not  believe  that sales  backlog is a  significant  factor in its
business.

         9.       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,
Quest Diagnostics, Inc. and SmithKline Laboratories,  Inc. and other independent
laboratories,   specialized   laboratories,   and  in-house  testing  facilities
maintained by hospitals.

                  Competitive factors include reliability and accuracy of tests,
price structure, service, transportation and collection networks and the ability
to establish relationships with hospitals,  physicians,  and users of drug abuse

<PAGE>

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.

                  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  laboratory  testing
business.

                  Product  Sales.  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  capabilities,  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.

                  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.

         10.      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.

     1.  Substance  Abuse and Mental Health  Services  Administration  (SAMHSA).
MEDTOX  Laboratories,  Inc.  has been  certified  by SAMHSA  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.

     2. 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)

<PAGE>

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 12 different  products and the average time for  clearance was 72
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.

     3. 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 MEDTOX Diagnostics, Inc. 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.  MEDTOX  Laboratories,  Inc. is a
CLIA licensed laboratory.

     4. 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. MEDTOX Laboratories,  Inc. is
registered with the DEA to conduct chemical analyses with controlled substances.
The MEDTOX Diagnostics,  Inc. facility in Burlington,  N.C. 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.

     5.  Additional   Laboratory   Regulations.   The   laboratories  of  MEDTOX
Laboratories,  Inc.  and certain of its  laboratory  personnel  are  licensed or
otherwise regulated by certain federal agencies, states, and localities in which
it conducts  business.  Federal,  state and local laws and  regulations  require
MEDTOX  Laboratories,  Inc. 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,  the  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.

     The laboratory  receives and uses 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.

         11.      Product and Professional Liability.

                  Laboratory Services. 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 1984. The insurance  policy covers those amounts the
Company  is  legally  obligated  to pay from  damages  resulting  from a Medical

<PAGE>

Incident,  which  arises out of a Failure to Render  Professional  Services.  To
date, the Company has not had any substantial  product liability and no material
professional service claims are currently pending.

                  Product Sales.  Manufacturing and marketing of products by the
Company entail a risk of product liability claims. In August,  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.  The  insurance  policy
covers  damages  that the Company is legally  obligated  to pay as a result from
bodily  injury and property  damage.  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.

         12.      Employees.

                  As  of  December  31,  1998,   the  Company  had  a  total  of
approximately  315 full time employee equivalents as compared to  approximately
305 full time employee equivalents at December 31, 1997. Of the approximate 315
employees, 285 work at and for MEDTOX Laboratories,  while the remaining 30 work
at MEDTOX Diagnostics, Inc.

                  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.

ITEM 2.  PROPERTIES.

     The   administrative   offices   and   laboratory   operations   of  MEDTOX
Laboratories,  Inc.  are located in a 45,207  square foot  facility in St. Paul,
Minnesota. The facility is rented under a lease which expires in March 2002. The
current annual rent, excluding operating costs, for the facility is $396,000 per
year.

                  The  Company  leases   approximately  33,000  square  feet  in
Burlington,  North  Carolina,  where it  maintains  the  offices,  research  and
development  laboratories,   production  operations,  and  warehouse  of  MEDTOX
Diagnostics,  Inc.  The total rent paid by the  Company for this site during the
fiscal year ended December 31, 1998 was approximately $122,000. These facilities
are  currently  leased  from Dr.  Samuel  C.  Powell,  a member  of the Board of
Directors  of the  Company.  The  Company is  currently  leasing  the space on a
month-to-month basis and intends to negotiate a new lease with Dr. Powell in the
near future.  The Company  believes it is renting  these  facilities on terms as
favorable as those available from third parties for equivalent premises.  In the
opinion of  management,  comparable  alternative  facilities  could be  obtained
without  disruption  of the  business  if a new  lease  with Dr.  Powell  is not
negotiated. 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 rent payment,  excluding  operating costs, is $170,345 per year.
The lease runs through  April,  2000.  The  facility is  currently  idle and the
Company is aggressively seeking a tenant to sub-lease the facility. The costs of
the facility have been considered in the Company's restructuring charge in 1996.
See  Note 8 to the  Notes of the  Consolidated  Financial  Statements  contained
herein.
<PAGE>

                  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 3.  LEGAL PROCEEDINGS.

                  The  Company has entered a  settlement  agreement  with United
States Drug Testing  Laboratories  who  asserted a claim of patent  infringement
against  the  Company  on August  20,  1996.  It was  alleged  that the  Company
infringes two patents allegedly owned by United States Drug Testing Laboratories
relating to forensically acceptable determinations of gestational fetal exposure
to drugs and other chemical  agents.  The Company while denying any infringement
has reached a settlement  agreement with United States Drug Testing Laboratories
whereby the Company will pay United States Drug Testing Laboratories $17,500 and
issue United States Drug Testing Laboratories 2,500 shares of common stock.

                  On  January  31,  1997,  the  Company  filed  suit in  Federal
District Court in Minnesota against Morgan Capital LLC, David Bistricer and Alex
Bistricer  alleging  violation in Section 16b of the Securities and Exchange Act
of 1934 and seeking  recovery  of more than  $500,000  in  short-swing  profits.
Messrs.  David and Alex Bistricer are former directors of the Company. On August
4, 1997,  the U.S.  District  Court  granted  Defendants'  motion to dismiss the
Company's  complaint,  ruling that the Defendants'  conduct did not constitute a
violation of Section 16(b).  On October 29, 1997, the Company filed an appeal of
that decision to the United States Court of Appeals for the Eighth  Circuit.  On
July 21, 1998,  the Eighth  Circuit  reversed the District  Court  dismissal and
remanded  the case to the  District  Court.  Cross  motions to  dismiss  and for
partial summary judgment are pending.

     The Company is a defendant in a lawsuit brought by a previous  landlord and
pending in the Circuit Court of Cook County, Illinois. The landlord alleges that
the  Company  breached  the terms of a lease the Company  attempted  to issue in
connection  with an asset  acquisition.  Discovery is continuing in the case. In
December 1998,  the Court granted  summary  judgment  against the Company on the
issue of liability  and the matter is set for trial in June 1999 on the issue of
damages.

ITEM 4.  SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS.

                  The  Annual  Meeting  (the  "1997  Annual   Meeting")  of  the
stockholders  of the Company  was held on  September  11,  1998.  The  following
individuals  were  elected to serve on the Board of Directors of the Company for
the ensuing  year and until their  respective  successors  are duly  elected and
qualified:  Harry G. McCoy, Pharm.D., Samuel C. Powell, Ph.D., Richard A. Braun,
Miles E. Efron and James W. Hansen. Also by a vote of 2,187,765 shares in favor
and 261,334 shares against, at the 1997 Annual Meeting,  the stockholders of the
Company approved an amendment to Article FOURTH of the Company's  Certificate of
Incorporation  to increase its number of authorized  common stock from 3,000,000
shares to 3,750,000  shares.  During the year ended  December 31, 1998, no other
matters were submitted to a vote of securities holders.

         The Company held a special meeting of stockholders on February 22, 1999
to adopt and approve an amendment of the Company's  Certificate of Incorporation
providing for a one for twenty reverse stock split of  outstanding  Common Stock
of the Company.  The  amendment was approved by a vote of 2,309,935 in favor and
162,644  against.  The reverse  split was effective on February 23, 1999 and the
stock began trading on the new basis February 24, 1999. All shares and per share
amounts  presented  in the  annual  report on Form 10-K  have been  adjusted  to
reflect the reverse split.

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  currently  trading under the symbol  "TOX".  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".  As of March 23, 1999, the number of
holders of record of the Common Stock was 2,843. 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. The quotations
shown  represent  inter dealer prices  without  adjustment  for retail  markups,
markdowns or commissions,  do not necessarily reflect actual  transactions,  and
have been  adjusted for the 1:20 reverse split which took effect on February 24,
1999.

         Third Quarter...........................    10                6 1/4
         Fourth Quarter.........................     7 1/2             5



                  On March 23,  1999,  the closing  price of the Common Stock as
reported by the American Stock Exchange was $3 7/8.

               No dividends  have been declared or paid by the Company since its
inception  and  management  of the Company  has no plans to pay  dividend in the
foreseeable  future. The Company's financial covenants under its debt instrument
may effectively preclude the Company from paying dividends.

Series A Preferred Stock

                  To help finance the  acquisition of the  predecessor to MEDTOX
Laboratories, Inc. and provide working capital, the Company issued 407 shares of
Series A Preferred  Stock in January  1996.  There are  currently  no  remaining
shares of Series A Preferred Stock outstanding.
<PAGE>

                  The Series A Preferred  Stock was  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  terminated.  The
Series A  Preferred  Stock  had no  voting  power  and had  certain  liquidation
preference  and dividend  rights.  The number of shares of Common Stock issuable
upon  conversion  of a share of Series A  Preferred  Stock  equaled  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  (based on  pre-reverse  split
market price) or (ii) 75% of the Market Price of the Common Stock on the day the
shares of Series A Preferred  Stock were  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.

                  No dividends on the Series A Preferred  Stock were declared or
paid prior to their conversion to Common Stock.

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

General
                  The Company  commenced  operations in June 1983 and until 1986
was a development  stage company.  The Company became engaged in the manufacture
and sale of 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. In February 1994, the Company  completed the
acquisition of PDLA. In January 1996, the Company  completed the  acquisition of
the predecessor of MEDTOX  Laboratories,  Inc. The results of operations for the
year ended  December  31,  1996  include  the  results of  operations  of MEDTOX
Laboratories,  Inc. for the period  January 30, 1996 through  December 31, 1996.
Since  inception,  the Company has  financed  its working  capital  requirements
primarily from the sale of equity securities and more recently debt financing.

Year ended December 31, 1998 Compared to Year ended December 31, 1997

Laboratory Services

                  Revenues from Laboratory  Services for the year ended December
31, 1998 were $27,070,000 as compared to $25,899,000 for the year ended December
31, 1997. The increase of 4.5% was primarily  attributable  to increase of 16.5%
in laboratory  samples for employment drug testing  services.  This increase was
due to increased sales from current clients as well as new clients. Revenue from
increase in sample volume was partially  offset by an 11.3%  decrease in average
per unit prices.

                  The  gross  margin  from  the  revenues   generated  from  the
laboratory  services was 31% for the year ended December 31, 1998 as compared to
a gross margin of 37.5% for the same period in 1997. The decline in gross margin
was primarily due to increased costs related to  implementation of new tests and
a decrease in the average selling price per laboratory  sample.  The decrease in
average  realized  selling price was partially  offset by savings  realized from
cost savings and improvements in the efficiency of laboratory operations.

                  Selling,  general  and  administration  expenses  for the year
ended  December 31, 1998 were  $7,929,000,  compared to $7,780,000  for the year
ended  December 31, 1997.  The increase of $149,000 or 2% in 1998 was the result
of  increased   costs  in  several  areas   including;   $379,000  in  increased
depreciation  expense,  $133,000 in increased group insurance  costs, a $123,000
increase  in  computer  information  systems  expense,  and  severance  expenses
totaling  $167,000  related to staff  resizing.  These increases were partially
offset by savings of $564,000 realized from reduced sales and marketing expenses
due to a restructuring of the sales and marketing group and an overall effort to
reduce and monitor costs.
<PAGE>

                  Research and  development  expenses  incurred  during the year
ended  December  31, 1998 were  $522,000  as  compared to $502,000  for the same
period in 1997.  This  increase of $20,000 was primarily the result of increased
in personnel costs due to scheduled salary increases.


                  The Company  periodically  undertakes a review of the value of
the remaining goodwill  associated with the acquisition of MEDTOX  Laboratories,
Inc.,  to  determine  if  the  value  is  supported  by  the  projected   future
undiscounted  cash flows.  Utilizing an  undiscounted  cash flow  analysis,  the
Company determined that the carrying value of the remaining goodwill  associated
with the MEDTOX  Laboratories,  Inc.  acquisition  is supported by the projected
cash flows at December 31, 1998.

                  The  Laboratory  Services  segment for the year ended December
31, 1998,  incurred interest and financing costs of $615,000,  compared to costs
of $609,000 incurred during the year ended December 31, 1997.

               The Company's restructuring reserve increased by $712,000 for the
year ended  December 31, 1998 as compared to the period ended December 31, 1997.
The increase in the reserve was due to an increase in the  projected  litigation
and settlement expenses relating to a lawsuit brought by a previous landlord and
pending in the Circuit Court of Cook County, Illinois. The landlord alleges that
the  Company  breached  the terms of a lease the Company  attempted  to issue in
connection  with an asset  acquisition.  Discovery is continuing in the case. In
December 1998,  the Court granted  summary  judgment  against the Company on the
issue of liability  and the matter is set for trial in June 1999 on the issue of
damages.

                  As a result  of the  above,  the net  loss for the  Laboratory
Services  segment  of the  Company  for the year  ended  December  31,  1998 was
($1,391,000), compared to the net income of $430,000 for the year ended December
31, 1997.

Product sales

                  Revenues  from Product  Sales for the year ended  December 31,
1998  decreased  7.1% to $2,505,000 as compared to $2,695,000 for the year ended
December 31, 1997. The decrease was primarily attributable to decreased sales in
substance abuse testing products and agricultural diagnostic products.

                  Product sales include the sales generated from substance abuse
testing products,  which  incorporates the EZ-SCREEN PROFILE and VERDICT on-site
test kits and other ancillary  products for the detection of abused  substances.
Sales from  these  products  decreased  15.0% to  $1,297,000  for the year ended
December 31, 1998 compared to sales of $1,525,000 in 1997. The Company  believes
that the  decrease in product  sales is primarily  due to increased  competition
from products  perceived as more user  friendly  than the Company's  traditional
products.  The Company also believes that the introduction of its new generation
of on-site test kits along with its patent  pending "test system" has placed the
Company in strong position to compete successfully in the on-site drug screening
market.  The first of these next generation test kits,  PROFILE(R)- II, received
pre-market  510(k)  clearance  from the U.S. Food & Drug  Administration  in the
fourth quarter.

                  Product  sales also include sales of  agricultural  diagnostic
products. Sales of these products decreased 37.8% to $458,000 for the year ended
December  31 1998,  compared to  $736,000  in 1997.  The primary  reason for the
decrease of $278,000 was the result of  decreased  purchases by the USDA for the
Company's  products.  The USDA's needs for the company's products vary from year
to year and sales to the USDA are expected fluctuate accordingly.

<PAGE>

                  Sales of contract manufacturing services,  microbiological and
associated  products increased 72.8% to $750,000 for the year ended December 31,
1998 compared to $434,000 in 1997.  This increase was due to increased  revenues
from both historical customers and new customers added in late 1997.

                    Gross margins from Product Sales for the year ended December
31, 1998 were 33.3%  compared to 37% for the year ended  December 31, 1997.  The
decrease in gross margin from product  sales was due to lower  overall  sales of
products and increased manufacturing costs related to new product development.

     Revenues  from  interest and other  income for the year ended  December 31,
1998 were $1,000 compared to $6,000 for the year ended December 31, 1997.

                  Selling,  general and  administration  expenses  for  products
sales  during the year ended  December  31,  1998 were  $1,045,000,  compared to
$946,000 for the year ended  December  31, 1997.  The increase of $99,000 or 10%
was  primarily  the  result  of   implementation   costs   associated  with  the
introduction of the Company's new generation on-site products.

                  Research and  development  expenses  incurred  during the year
ended  December  31, 1998 were  $631,000  as  compared to $463,000  for the same
period in 1997.  The increase of $169,000 or 36.5% was  primarily  the result of
costs  associated with the  development of the Company's new generation  on-site
products.

                  For the year  ended  December  31,  1998,  the  Product  Sales
segment incurred interest and financing costs of $59,000. There were no interest
charges  incurred by this segment  during the year ended  December 31, 1997. The
interest and finance costs were the result of the funds  borrowed by the Company
to fund asset purchases and working capital requirements.

     As a result of the above,  the product  sales segment net loss for the year
ended December 31, 1998 was  ($906,000),  compared to the net loss of ($405,000)
for the year ended December 31, 1997.


Year ended December 31, 1997 Compared to Year ended December 31, 1996

Laboratory Services

                  Laboratory  service  revenues  were  $25,899,000  for the year
ended December 31, 1997 as compared to  $23,541,000  for the year ended December
31, 1996.  This  increase of 10% was  primarily  the result of the timing of the
acquisition  of MEDTOX  whereby the Company  realized  revenues  from MEDTOX for
approximately eleven months during the year ended December 31, 1996, as compared
to the complete year ended December 31, 1997. Had the acquisition of MEDTOX been
effective  January 1, 1996,  the Company would have had revenues of  $24,741,000
from laboratory services during the year ended December 31, 1996, as compared to
the  $25,899,000  realized from the sale of laboratory  services during the year
ended December 31, 1997, this would represent a pro forma increase of $1,158,000
or 5%. The 5% increase was the result of  increased  sales from new and existing
customers.

                    The  gross  margin  from  the  revenues  generated  from the
laboratory  services was 37.5% for the year ended  December 31, 1997 as compared
to a gross margin of 34.8% in 1996. During the year ended December 31, 1997, the
Company was able to offset  declining  average  selling prices by reducing costs
through the consolidation of laboratory  operations in 1996 as well as continued
improvements in efficiency of laboratory operations.
<PAGE>

                  Selling,  general and  administration  expenses for laboratory
services  for the year ended  December  31,  1997 were  $7,780,000,  compared to
$8,584,000 for the year ended December 31, 1996. The $804,000 reduction in these
expenses  in 1997 was  primarily  the  result of the  consolidation  of  certain
administrative  functions  into  the  MEDTOX  facility,  decreased  amortization
expense, and an overall effort to monitor and control costs.

                    Research and development expenses incurred in the laboratory
services  segment  during the year ended  December  31,  1997 were  $502,000  as
compared to $398,000 for the same period in 1996.  This increase of $104,000 was
primarily the result of increased new assay  development  for new drug entities,
new assays for existing  metabolites of drugs and other toxins,  and improvement
in  existing  assays  with  the  goals of  increasing  the  assay's  robustness,
sensitivity, accuracy, precision, specificity, and cost.

     For the year  ended  December  31,  1997,  the  segment  had  interest  and
financing costs of $609,000,  compared to costs of $469,000  incurred during the
year ended December 31, 1996. This increase was the result of the funds borrowed
by the Company to complete the financing for the acquisition of MEDTOX.

                  During  the  year  ended   December  31,  1996,   the  Company
determined that it would be beneficial to consolidate the laboratory  operations
of PDLA into the laboratory operations at MEDTOX as well as to down size certain
administrative  positions  at  both  PDLA  and  MEDTOX  in  order  to  eliminate
duplicative  functions.  As a result of these  restructuring  steps, the Company
recorded  charges  of  $2,424,000  during  the year  ended  December  31,  1996,
including  a  $101,000  write  down of the  goodwill  associated  with  the PDLA
acquisition,  to cover  certain costs of the  restructuring.  The Company had no
such charge during the year ended December 31, 1997.

                  During 1996 the laboratory  testing  industry was undergoing a
period of intense  competition,  and MEDTOX  began to  experience,  a  declining
average  selling  price.  This trend to  continued  through the end of 1998.  In
addition,  during 1996 the Company  expected that  alternative  testing methods,
including  available  on-site  testing,  or  on-site  testing  that  may  become
available in future years, may make the current forms of laboratory testing less
competitive.  While the Company  expects to continue to develop and/or  evaluate
new testing  technologies,  it was believed  that the current form of laboratory
testing at MEDTOX could not support the carrying  value of the goodwill from the
sale of that laboratory to the Company.

     Utilizing an undiscounted cash flow analysis,  the Company  determined that
the  carrying  value  of the  remaining  goodwill  associated  with  the  MEDTOX
acquisition  exceeded  the  estimated  future cash flows to be generated by that
business.  Accordingly,  the  Company  recorded a  write-off  of  $6,016,000  at
December 31, 1996. The noncash  write-off of the goodwill has reduced the future
amortization expense of the Company by $317,000 per year.

     As a result of the above,  the net income for the year ended  December  31,
1997 for the laboratory services segment was $430,000,  compared to the net loss
of ($9,156,000) for the year ended December 31, 1996.

Product Sales

                  Revenues  for product  sales for the year ended  December  31,
1997  decreased  8.9% to $2,695,000 as compared to $2,957,000 for the year ended
December 31, 1996. The decrease is primarily  attributable to decreased sales of
the Company's agricultural diagnostic products.

                  Product sales include the sales generated from substance abuse
testing products, which incorporates the EZ-SCREEN and VERDICT on-site test kits

<PAGE>

and other ancillary products for the detection of abused substances.  Sales from
these products increased 3.7% to $1,525,000 for the year ended December 31, 1997
compared to $1,471,000 in 1996.

                  Product  sales also include sales of  agricultural  diagnostic
products. Sales of these products decreased 33.7% to $736,000 for the year ended
December 31 1997,  compared to sales of $1,110,000  in 1996.  For the year ended
December  31,  1996,  the  Company had sales of  $361,000  which were  generated
through the former  operations of Bioman.  Excluding  these  revenues,  sales of
agricultural  diagnostic  products were $749,000 for the year ended December 31,
1996. As such,  the sales of these  products on a pro forma basis  declined 1.7%
for the year ended December 31, 1997 as compared to the same period in 1996. The
primary  reason for the increase was due to increased  purchases by the USDA for
the Company's products.

                  Sales of contract manufacturing services,  microbiological and
associated  product  sales were  $434,000  for the year ended  December 31, 1997
compared  to  $301,000  for the same period in 1996.  This  increase  was due to
increased revenues from contract manufacturing services.

                  Revenues  generated  from the shipment of products to the U.S.
Department  of Defense  were $75,000 for the year ended  December 31, 1996.  The
Company had no such sales during the year ended December 31, 1997 and 1998.

                  For the year ended  December  31,  1997,  the  Company  had no
revenues  from  royalties  and fees,  compared  to  $90,000  for the year  ended
December 31, 1996.  This  decrease was primarily due to the absence of royalties
from American  Medical  Laboratories,  Inc.  ("AML") as the  agreement  with AML
expired in 1996.

     Revenues  from  interest and other  income for the year ended  December 31,
1997 were $6,000 compared to $138,000 for the year ended December 31, 1996.

                  Gross margins from the sales of both manufactured products and
products  purchased  for resale for the year ended  December  31,  1997 were 37%
compared to 27% of sales of these  products  during the year ended  December 31,
1996.  This  increase in gross margin from product sales is primarily the result
of  the  increased   sales  of  the  EZ-SCREEN   PROFILE  product  and  contract
manufacturing  services,  as  well as  reduced  costs  as a  result  of  certain
restructuring steps taken in 1996.

                  Selling,  general  and  administration  expenses  for the year
ended December 31, 1997 were $946,000, compared to $3,559,000 for the year ended
December  31,  1996.  The  $2,613,000  reduction  in these  expenses in 1997 was
primarily the result of the  consolidation of certain  administrative  functions
into the MEDTOX facility,  decreased amortization expense, and an overall effort
to monitor and control costs.

                  Research and  development  expenses  incurred  during the year
ended  December  31, 1997 were  $463,000  as  compared to $882,000  for the same
period in 1996. The reduction of $419,000 in research and  development  expenses
is primarily  the result of a reduction of personnel and a refocus of efforts in
the research and  development  function  associated  with the Company's  on-site
products.

                  During  the  year  ended   December  31,  1996,   the  Company
determined  that to improve the  operating  results of the Company,  it would be
necessary to sell the former  operations of Bioman,  close its farm facility and
reduce its work force at its Burlington, North Carolina location. As a result of
these  restructuring  steps,  the Company recorded charges of $25,000 during the
year ended December 31, 1996 to cover certain costs of the  restructurings.  The
Company had no such charge during the year ended December 31, 1997.
<PAGE>

     As a result of the above,  the net loss for the year ended  December 31,
1997 for the product  sales  segment was  $405,000,  compared to the net loss of
$3,653,000 for the year ended December 31, 1996.

                  In March 1997, the Securities  and Exchange  Commission  Staff
(the "Staff")  announced its position on accounting for preferred stock which is
convertible  into common stock at a discount from the market rate at the date of
issuance.  To comply with this position,  the Company recorded a deemed dividend
of $6,783,000 related to the January 1996 sales of the Series A Preferred Stock.
This  resulted  in a reported  net loss  applicable  to common  stockholders  of
$19,592,000 for the year ended December 31, 1996.

Material Changes in Financial Condition

Laboratory Services

                  At December 31, 1998,  net accounts and notes  receivable  for
laboratory  services  were  $5,570,000.  This  $415,000  increase as compared to
$5,155,000  at December 31, 1997 was a result of a decrease in the allowance for
bad debts and an increase in gross billings prior to pass through costs,  in the
fourth quarter of 1998 as compared to the same quarter in 1997.

                  Inventories  were  $432,000 at December  31, 1998  compared to
$457,000 at December 31, 1997.

                  Prepaid  expenses and other  assets were  $503,000 at December
31, 1998 as compared to $351,000 at December 31, 1997.  The increase of $152,000
is primarily the result of the renewal of insurance policies, annual maintenance
contracts, licenses and fees, and an increase in prepaid supplies.

                  The balance of equipment and improvements at December 31, 1998
was $10,275,000 as compared to a balance of $9,030,000 at December 31, 1997. The
increase of  $1,245,000  was the result of purchases  of  equipment  and capital
improvements  for the laboratory  operation to improve  efficiencies  and reduce
operating costs.

                  As of December 31, 1998,  accounts payable totaled  $3,345,000
compared to $3,659,000 at December 31, 1997. The decrease of $314,000,  or 8.6%,
is primarily the result of more timely payment of vendors.

                  Accrued  expenses  were  $1,586,000  at December 31, 1998,  as
compared to $1,162,000 at December 31, 1997. The increase of $424,000, or 36.5%,
was the result of the laboratory  supplies  received but not invoiced,  accruals
for  severance  expenses,  and an accrual  for the United  States  Drug  Testing
Laboratories litigation settlement.

                  At December 31, 1998,  the laboratory  services  segment had a
total balance of leases  payable of $702,000,  compared to a balance of $414,000
at December 31, 1997.  The increase in the balance of the leases payable was the
result of the leases of certain equipment to improve  operating  efficiencies in
the laboratory.

                   At December 31, 1998, laboratory services had a total balance
of  restructuring  accruals of  $1,155,000  compared to a balance of $786,000 at
December 31, 1997. The increase in the balance of the restructuring  accruals of
$369,000,  or 47%,  was the result of an increase  of  $712,000 in reserves  for
pending litigation expenses less $343,000 in restructuring expense payments made
during 1998.

                  At December  31,  1998,  the Company had a total loan  balance

<PAGE>

owed to its  financial  lender of  $5,268,000,  compared  to a total  balance of
$5,016,000  owed at December 31, 1997. The net increase of $252,000,  or 5%, was
primarily  the result of  increased  borrowings  by the Company from its line of
credit to pay operating expenses as well as fund the purchases of certain assets
to improve operating efficiencies.

Product Sales

     At December  31,  1998,  net  accounts  receivable  for product  sales were
$417,000. This $39,000 decrease as compared to $456,000 at December 31, 1997 was
primarily due an improvement in days sales outstanding (DSO).

                  Prepaid expenses and other assets were $21,000 at December 31,
1998 as compared to $64,000 at December  31,  1997.  The  decrease of $43,000 is
primarily  the  result  of the  timing  of the  renewal  of  annual  maintenance
contracts, annual licenses and fees.

                  The balance of equipment and improvements at December 31, 1998
was  $2,787,000 as compared to a balance of $2,882,000 at December 31, 1997. The
decrease of $95,000 was the result of obsolete  equipment disposed of during the
year.

                  As of December 31, 1998,  accounts  payable  totaled  $186,000
compared to $109,000 at December  31, 1997. The increase of $77,000,  or 70%, is
primarily the result of increased  purchases of supplies relating to development
and  production of the Company's new  generation  on-site  products,  as well as
certain capital expenditures.

                  Accrued  expenses  were  $138,000 at  December  31,  1998,  as
compared to $164,000 at December 31, 1997.

                  At December 31, 1998, and December 31, 1997, the product sales
segment had no leases payable.

                  At December  31, 1998,  the product  services had a total loan
balance owed to its financial lender of $752,000, compared to a total balance of
$0 owed at December 31, 1997.  The net  increase of $752,000,  or 100%,  was the
result of allocation of the portion of the Company's debt secured by the product
sales  segment  being  allocated  to the  segment.  Funds were used for  working
capital  as  well  as   purchases  of  certain   assets  to  improve   operating
efficiencies.


Liquidity and Capital Resources

                  The working  capital  requirements  of the  Company  have been
funded primarily by cash received from debt financing. At December 31, 1998, the
Company had checks written in excess of bank balances in the amount of $142,000.
Cash and cash  equivalents at December 31, 1998 of $0, compared to $58,000 as of
December 31, 1997.

                  The  Company is relying on  expected  positive  cash flow from
operations,  its line of credit,  in addition  to funds  received  from  private
placements of subordinate debt (see discussion below) to fund its future working
capital  and asset  purchases.  The  amount of credit on the  revolving  line of
credit is based primarily on the receivables of the Company and, as such, varies
with the  accounts  receivable,  and to a lesser  degree  the  inventory  of the
Company. As of December 31, 1998, the Company had total availability of $367,000
on the line of credit of which $115,000 was borrowed, leaving a net availability
of $252,000 as of December 31, 1998.
<PAGE>

                  On  January  14,  1998,  the  Company  entered  into a  Credit
Security  Agreement (the "Wells Fargo Credit  Agreement"  f/k/a "Norwest  Credit
Agreement")  with Wells  Fargo  Business Credit  (Wells  Fargo),  f/k/a  Norwest
Business Credit. The Wells Fargo Credit Agreement consists of (i) a term loan of
$2,125,000 which matures on January 15, 1999, (ii) a term loan of $700,000 which
matures on January 15,  1999,  (iii) a revolving  line of credit  based upon the
balance of the Company's  trade  accounts  receivable,  and (iv) a note of up to
$1,200,000  for the  purchase of capital  equipment  for 1998.  The term loan of
$2,125,000  carries an interest rate equal to 1.25% above the publicly announced
rate of interest by Wells Fargo Bank  Minnesota,  N.A.  (the "Base  Rate").  The
$700,000  term loan has an  interest  rate equal to 3.00% above the Base Rate as
does  the line of  credit.  The note for the  capital  expenditures  carries  an
interest  rate equal to 1.25%  above the Base Rate.  The Company  utilized  $4.5
million of the  proceeds  received  from Wells Fargo to pay off the  outstanding
loan balance owed to its former lender.

                  On November  24,  1998 the  Company  and Wells Fargo  Business
Credit amended the Credit  Agreement.  The amended Wells Fargo Credit  Agreement
consists  of (i) an increase  in the  remaining  balance on the term loan to the
original  amount of  $2,125,000  and  extension  of the maturity to November 25,
2001,  (ii) an increase in the  remaining  balance on the $700,000  term loan to
$417,000 and an  extension of its maturity to June 1, 1999,  and (iii) a note of
up to $1,000,000 for the purchase of capital equipment for 1999.

                  As of December  31,  1998,  the Company was not in  compliance
with the  provisions  of the minimum debt service  coverage  ratio,  minimum net
income,  and minimum book net worth  covenants of the Norwest Credit  Agreement.
However, on April 12, 1999, the Company amended the Wells Fargo Credit Agreement
(the Third  Amendment).  The Third Amendment waived the Company's  noncompliance
with these  covenants  at December  31, 1998 and also  modified the terms of the
financial  covenants  for 1999.  Management  is of the  opinion  the Company can
achieve the modified financial covenants throughout the course of 1999.

                  At December  31,  1998,  the Company  received  $175,000  from
private  placements of  subordinated  debt, with a maturity date of December 31,
2001. The debt carries an interest rate of 12% and has accompanying  warrants to
purchase a number of shares of common  stock equal in  exercise  price to 25% of
the  notes  purchased.  As of March  23,  1999,  the  Company  had  received  an
additional  $400,000 from this debt offering.  The Company is continuing to sell
these securities and may sell up to $1,500,000 in the private placement.

                  The funds received from the amendment to the Norwest  Business
Credit  Agreement and the private  placements of subordinated  debt were used to
fund the working capital needs of the company.

                  In  the   short   term,   the   Company   believes   that  the
aforementioned   capital  along  with   additional   funds   received  from  the
subordinated  debt offering  will be  sufficient  to fund the Company's  planned
operations  through  1999.  While there can be no assurance  that the  available
capital will be sufficient to fund the future  operations of the Company  beyond
1999,  the Company  believes that  consistent  profitable  earnings,  as well as
access to capital,  will be the primary basis for funding the  operations of the
Company for the long term.

                  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)  continue  to  selectively  pursue  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.

Impact of Year 2000

                  The "Year 2000" issue arises from the fact that many  computer
systems rely on a two-digit date code to identify the year (e.g. 98 to represent
1998) and thus may not be able to  differentiate  between  the year 2000 and the
year 1900. If not corrected,  systems processing date-dependent  information may
fail or create erroneous results, causing disruptions of operations,  including,
but not  limited  to, a  temporary  inability  to process  transactions,  report
results, send invoices, or engage in similar normal business activity.

                  The Company  has  completed  its  assessment  of its  internal
computer  systems and has determined  that  modification  to some portion of its
software is required so that its computer systems function properly with respect
to dates in the year 2000 and beyond.  The Company presently  believes that with
modification to existing software and conversion to new software,  the Year 2000
issue will not pose significant operational problems for its computer systems.

                  The Company has initiated formal communication with all of its
significant suppliers to determine the extent to which the company is vulnerable
to those third parties ability to resolve their own Year 2000 issues.  There can
be no guarantee that the systems of other  companies on which the Company relies
will be timely  converted or that a failure to convert or a  conversion  that is
incompatible  with the Company's  system would not have an adverse effect on the
Company's  systems.  Supplier  response is not yet  complete  and the Company is
continuing to work to conclude this area of its Year 2000 assessment.

                  The Company anticipates completing the Year 2000 project prior
to any  adverse  impact  on its  computer  operating  system,  however,  if such
modifications and conversions are not made, or completed  timely,  the Year 2000
issue could have a material impact on the operations of the Company. The Company
continues to assess its readiness  relative to Year 2000 issues and will develop
a contingency plan for all items not resolved at the end of the first quarter.

                  The  cost of the  Year  2000  project  is not  expected  to be
material.  Changes required to internally  supported software are minor compared
to the modifications  performed in the normal course of business and the Company
plans to use internal  resources and delay other projects to complete these Year
2000 modifications.  Updates to externally  supported software are covered under
existing  service  contracts or are not  anticipated  to have costs  material in
nature.

                  The assessment of the impact, cost, and completion of the Year
  2000 project is based on  management's  best  estimates.  Actual results could
  differ materially from those anticipated by factors including, but not limited
  to, the continued availability of certain resources,  third party modification
  plans, and the ability to locate and correct all relevant computer codes.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

                  Reference  is  made  to the  financial  statements,  financial

         ON ACCOUNTING AND FINANCIAL DISCLOSURE.

               Effective May 27, 1998, the Registrant  terminated  Ernst & Young
LLP as its independent accounting firm. The termination of Ernst & Young LLP was
approved by the Audit  Committee of the Board of  Directors  of the  Registrant.
There  were no  disagreements  with Ernst & Young LLP during the last two fiscal
years ending December 31, 1997.  Accordingly,  Ernst & Young LLP has not advised

<PAGE>

the  Registrant  of (i) the absence of the internal  controls  necessary for the
Registrant to develop reliable financial statements,  (ii) any information which
would cause Ernst & Young LLP to no longer rely on management's representations,
or that Ernst & Young LLP was  unwilling  to be  associated  with the  financial
statements  prepared by management,  (iii) any need to expand  significantly the
scope of its audit,  or any  information  that if further  investigated  may (a)
materially  impact the fairness or  reliability  of either a  previously  issued
audit report or the underlying  financial statements or any financial statements
for any  fiscal  period  subsequent  to the  date of the most  recent  financial
statements covered by an audit report or (b) cause it to be unwilling to rely on
management's  representations  or be associated with the Registrant's  financial
statements,  or (iv) any  information  that has come to the attention of Ernst &
Young LLP that it concluded  materially  impacts the fairness or  reliability of
either  (a) a  previously  issued  audit  report  or  the  underlying  financial
statements or (b) any financial  statements  issued or to be issued covering any
fiscal  period  subsequent to the date of the most recent  financial  statements
covered by an audit report.

               Effective June 3, 1998, the Registrant  engaged Deloitte & Touche
LLP as its  independent  accounting  firm.  Neither the Registrant or any of its
subsidiaries has had any prior relationships with Deloitte & Touche LLP.

(1)      Mr. Heath  resigned as Vice  President  of Finance and Chief  Financial
         Officer on 7/31/98.  10,000  options to acquire  shares  were  canceled
         effective  7/31/98.  The remaining 2,500 options to acquire shares were
         fully vested at 12/31/98.

(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.

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 three stock  option  plans,  a 1983 Stock  Option Plan for  employees  which
expired on June 23, 1993, the Equity  Compensation Plan which was adopted by the
shareholders  of the annual meeting in 1993 to replace the 1983 Incentive  Stock
Option Plan, and a 1991 Non-Employee Director's Plan for members of the Board of
Directors who are not employees of the Company.

Compensation of Directors

         All  directors  who are not  employees of the Company  receive $500 per
month for their service as a director.  All directors  are also  reimbursed  for
expenses incurred in attending board of directors' meetings and participating in
other activities.

Employment Contracts

         Harry G. McCoy, Chairman of the Board of Directors and President of the
Company, has an employment agreement with the Company covering the period ending
December  31,  1999,  which  by its  term is  extended  thereafter  in  one-year
increments  unless Dr.  McCoy  provides  written  notice of  termination  to the
Company at least sixty (60) days prior to the date of termination. The agreement
may also be terminated  by mutual  consent or due to death or for "cause," or as
described  below. The employment  agreement  provides for an annual salary of at
least  $199,650  and certain  fringe  benefits.  If Dr.  McCoy's  employment  is
terminated  by the  Company  other than for cause,  or if Dr.  McCoy  chooses to
terminate the agreement voluntarily, following (i) a change in control; (ii) any
relocation  to which Dr.  McCoy has not  agreed to of  greater  than  fifty (50)
miles;   or  (iii)  any  material   reduction  in  the  level  of  Dr.   McCoy's
responsibility,  position,  authorities or duties;  or (iv) the Company breaches
any of its  obligations  under the  Agreement,  Dr.  McCoy will be entitled to a
Severance Award. The Severance Award consists of Dr. McCoy's base salary, health
insurance  and bonus plan  payments for the greater of twelve (12) months or the
then remaining term of employment under the Agreement.
<PAGE>

         The employment agreement contains a Covenant Not to Compete whereby for
a period of twelve (12) months  after the  termination  of  employment  with the
Company,  Dr. McCoy agrees that he will not, directly or indirectly,  either (a)
have any interest in (b) enter the employment of, (c) act as agent,  broker,  or
distributor for or advisor or consultant to, or (d) provide  information  useful
in conducting  the business of the Company to solicit  customers or employees on
behalf of the Company to any person, firm,  corporation or business entity which
is  engaged,  or which  Dr.  McCoy  reasonably  knows is  undertaking  to become
engaged, in the United States in the business of the Company.

         Richard J. Braun, Chief Executive Officer,  has an employment agreement
with the Company with the same terms as Dr. McCoy.

         Kevin Wiersma,  Vice President and Controller has a severance agreement
with the Company  covering the period  December  31, 1999,  which by its term is
extended  thereafter  in one-year  increments  unless  either the Company or Mr.
Wiersma provides written notice to the other party at least six (6) months prior
to the end of the original  term or each renewal  period or unless the agreement
is otherwise terminated due to death, permanent disability,  or for "cause." The
employment  agreement  provides  for an annual  salary of at least  $95,000  and
certain fringe benefits. If Mr. Wiersma's employment with the Company terminates
during  the  term of the  agreement  involuntarily,  other  than an  involuntary
termination on account of misconduct,  he will be entitled to a Severance Award.
The Severance Award consists of payment of an amount equal to Mr. Wiersma's then
current annual salary plus certain health benefits over the course of the twelve
(12) month period following Mr. Wieresma's termination.

         Three other key  employees  of the Company  have  severance  agreements
similar to Mr. Wiersma's agreement.

Compensation Committee and Decision Making

         The  compensation  of  executive  officers  of the Company for 1998 was
determined by the Compensation  Committee which is currently  comprised of James
W. Hansen, Miles E. Efron, and Samuel C. Powell. Stock options are awarded under
the Company's Equity  Compensation  Plan and  Non-Employee  Director Plan by the
Compensation  Committee.  All  non-employee  directors  were eligible to receive
stock options under the Company's 1991  Non-Employee  Director Plan,  which is a
formula  plan in  accordance  with the  requirements  of Rule  16b-3  under  the
Securities Act of 1934, as amended.

Report of the Compensation Committee on Executive Compensation

In General

         The Committee has three primary goals for executive compensation at the
Company.

o        Retaining good performers,
o        Rewarding executives appropriately for performance, and
o        Aligning executives' interests with those of stockholders.

         Currently,  executive pay consists of three  elements that are designed
to meet those objectives:

o    Base salary is paid based  primarily on job  responsibilities  and industry
     job comparison.  The Committee believes that base salaries at approximately
     industry averages are essential to retaining good performers.
o    Stock options,  which allow executives to benefit when the market price 
     of the Company's stock  increases.  

<PAGE>

o    Bonuses to be paid upon the attainment of certain financial objectives and
     individual circumstances when warranted.

Following is additional information regarding each of the above elements.

Base Salary

         Base  salary  increases  for  executive  officers  have been modest and
consistent with job performance and increases in responsibility.

Bonus

         Kevin   Wiersma   received  a  bonus  in  1998  as  part  of  incentive
compensation for meeting certain performance-related goals.

Stock Options

         In 1998, certain executive officers received incentive stock options to
purchase  a total of  117,500  shares.  The  number of  options  granted  to the
executive  officers  represented 59% of the total options granted in 1998 to all
employees.

Summary

         Currently,  the Company's  executive  compensation  program rewards the
following elements of performance.

o   Individual performance is rewarded through continued employment with the 
    Company.
o   Stock price performance is rewarded through increases in the value of stock 
    options.
o   Financial performance of the Company is rewarded through payments of bonuses
    upon the attainment of certain financial goals

         The Committee  believes that the current  program has been effective in
rewarding executives  appropriately for performance,  retaining good performers,
and  aligning  executives'  interests  with  those of  stockholders.  While  the
Committee is satisfied  with the current  compensation  system,  it reserves the
right to make  changes to the program as are  necessary  to continue to meet its
stated goals in future years.

         Benefits   also  are  offered  to  officers   that  are  not  based  on
performance.  Such  benefits  provide a safety net of protection in the event of
illness,  disability,  death, retirement,  etc. Such a safety net is provided to
all full time employees of the Company.

Chief Executive Officer Pay

         Amounts earned during 1998 by the Chief Executive  Officer,  Richard J.
Braun, are shown in the Summary Compensation Table.  Achievements by the Company
which were deemed material to the Chief Executive Officer's compensation include
the  attainment  of  profitability  for 1997 for the first time in the Company's
history. For the year ended December 31, 1997, the Compensation  Committee used,
in its  deliberations  on  executive  compensation,  these  criteria  and  other
accomplishments.

ITEM 13.          CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

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  33,000  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, 1998 was  approximately  $122,000.  The Company  believes the rent
amount paid to Dr. Powell is consistent with market rates.

INDEPENDENT AUDITORS' REPORT


The Shareholders and Board of Directors
Medtox Scientific, Inc.

We  have  audited  the  accompanying   consolidated   balance  sheet  of  Medtox
Scientific,  Inc.  (formerly EDITEK,  Inc.) and Subsidiaries (the Company) as of
December  31,  1998  and the  related  consolidated  statements  of  operations,
stockholders'  equity,  and cash flows for the year then  ended.  Our audit also
included the financial  statement  schedule  listed in the index as Item 14.a.2.
These  financial  statements  and  the  financial  statement  schedule  are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audit.

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 1998  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 our audit provides a reasonable basis for our opinion.

In our opinion,  such consolidated  financial  statements present fairly, in all
material  respects,  the  financial  position  of Medtox  Scientific,  Inc.  and
Subsidiaries  as of December  31, 1998 and the results of their  operations  and
their cash flows for the year then ended, in conformity with generally  accepted
accounting  principles.  Also, in our opinion, such financial statement schedule
when considered in relation to the basic consolidated financial statements taken
as a whole,  presents fairly in all material  respects the information set forth
therein.

                            MEDTOX SCIENTIFIC, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     YEARS ENDED DECEMBER 31, 1998 AND 1997

1.   Summary of significant accounting policies

     The Company - In May 1997,  the Company  changed  its  corporate  name from
     EDITEK,  Inc.  to  MEDTOX  Scientific,   Inc.  (MEDTOX).  The  consolidated
     financial  statements  include the  accounts of MEDTOX and its wholly owned
     subsidiaries,  MEDTOX Laboratories,  Inc. (MEDTOX  Laboratories) and MEDTOX
     Diagnostics,  Inc. (MEDTOX  Diagnostics)  (collectively  referred to as the
     Company).

     MEDTOX Laboratories  provides laboratory  analyses,  logistics  management,
     data  management,  and program  management  services.  Laboratory  analyses
     including  clinical  testing  services for the  detection of  substances of
     abuse and other toxins in biological  fluids and tissues.  Logistics,  data
     and  program  management  services  include  courier  services  for medical
     specimen transportation, management programs for on-site drug testing, data
     collection  and reporting  services,  coordination  of specimen  collection
     sites, and medical surveillance program management.

     MEDTOX  Diagnostics  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  as well as  distribution  of  agridiagnostic  and  food  safety
     testing products.

     All   significant   intercompany   transactions   and  balances  have  been
eliminated.

     Cash and Cash  Equivalents  - Cash and cash  equivalents  include  cash and
     highly liquid investment maturing within three months when purchased.

     Trade Accounts  Receivable - Sales are made to local and national customers
     including corporations, clinical laboratories, government agencies, medical
     professionals,  law  enforcement  agencies,  and  health  care  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, 1998 and 1997.

     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.
<PAGE>

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

     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 the 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.

     Income (Loss) per Share of Common Stock - Income (loss) per share of common
     stock amounts are based on the weighted  average number of shares of common
     stock  outstanding,  as well as shares of common stock that would have been
     issued and  outstanding  in certain  transactions  had the  Company had the
     necessary  number of authorized  shares of common  stock.  All other common
     stock equivalents were anti-dilutive and therefore were not included in the
     computation of income (loss) per share for all periods presented.

     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. In 1996, the Company recorded goodwill  write-offs
     totaling $6,117,000 (see Note 4).

     Impairment of Long-Lived  Assets - The Company  periodically  evaluates the
     carrying value of long-lived assets and long-lived assets to be disposed of
     for potential impairment.  The Company considers projected future operating
     results,  cash  flows,  trends  and  other  circumstances  in  making  such
     estimates and evaluations.  When the carrying value of any long-lived asset
     exceeds its projected  undiscounted cash flows, an impairment is recognized
     to reduce the carrying value to its fair market value. Losses on long-lived
     assets to be disposed of are  determined in a similar  manner,  except that
     the fair market values are reduced for the costs to sell.

     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  reclassifications  have been made to the 1997
     and  1996  consolidated  financial  statements  to  conform  with  the 1998
     presentation. These reclassifications had no effect on net income (loss) or
     total stockholders' equity as previously reported.

     Stock-Based  Compensation  -  SFAS  No.  123,  Accounting  for  Stock-Based
     Compensation,  requires  companies to measure  employee stock  compensation
     plans based on the fair value method of accounting.  However, the statement

<PAGE>

     allows the  alternative  of continued  use of Accounting  Principles  Board
     Opinion (APBO) No. 25,  Accounting for Stock Issued to Employees,  with pro
     forma  disclosure of net income and earnings per share determined as if the
     fair value  method had been  applied in measuring  compensation  cost.  The
     Company elected the continued use of APBO No. 25.

     Comprehensive  Earnings  -  Comprehensive  earnings  is a  measure  of  all
     nonowner  changes in  shareholders'  equity and includes  such items as net
     earnings,  certain  foreign  currency  translation  items,  minimum pension
     liability  adjustments,  and  changes  in the  value of  available-for-sale
     securities. In 1998, 1997, and 1996, comprehensive earnings for the Company
     were equivalent to net earnings as reported.

     Derivative  Instruments and Hedging  Activities - SFAS No. 133,  Accounting
     for Derivative Instruments and Hedging Activities,  was issued in June 1998
     and   establishes   accounting  and  reporting   standards  for  derivative
     instruments.  The statement  requires  recognition  of all  derivatives  as
     either  assets  or  liabilities  in the  statement  of  financial  position
     measured  at fair value and will be  effective  in fiscal  year  2000.  The
     Company has not yet  completed its analysis of the impact SFAS No. 133 will
     have on its consolidated financial statements.

2.       SEGMENTS

     The  Company  adopted  SFAS  No.  131,  Disclosures  about  Segments  of an
     Enterprise  and Related  Information,  in 1998,  which  changes the way the
     Company reports information about its operating  segments.  The information
     for 1997 and 1996 has been restated to conform to the 1998 presentation.

     The Company has two  reportable  segments:  Product Sales and Lab Services.
     The  Product  Sales  segment  is made up  entirely  of MEDTOX  Diagnostics.
     Products manufactured include easy to use, inexpensive,  on-site drug tests
     such as PROFILE II,  EX-SCREEN,  EX-QUANT,  and  VERDICT.  The Lab Services
     segment  includes MEDTOX  Laboratories and CMS.  Services  provided include
     forensic toxicology,  clinical toxicology,  heavy metals analyses,  courier
     delivery, and medical surveillance.

     In evaluating financial performance,  management focuses on net income as a
     segment's  measure  of  profit  or loss.  The  accounting  policies  of the
     segments  are the same as those  described  in the  summary of  significant
     accounting policies (see Note 1).

3.   ACQUISITIONS

     In January 1996, the Company  acquired  MEDTOX  Laboratories,  a toxicology
     laboratory  located in Saint Paul,  Minnesota.  The purchase  price was $24
     million, which included $19 million cash and the issuance of 125,865 shares
     of common  stock.  The  acquisition  was  accounted  for under the purchase
     method of accounting  under which the Company  recorded  approximately  $22
     million of goodwill.  The goodwill is being  amortized  over a period of 20
     years (see Note 4).

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

4.   GOODWILL WRITE-OFF

     In 1996, the Company reviewed the value of the goodwill associated with the
     acquisition  of MEDTOX  Laboratories.  The  purpose  of the  review  was to
     determine if the value of the goodwill,  generated as a result of the price
     paid by the Company for MEDTOX  Laboratories,  was in fact supported by the
     projected  future  benefit to the  Company as measured  by  projected  cash
     flows.

     Given  the  highly  competitive  nature  of the  testing  marketplace,  the
     industry  and  MEDTOX  Laboratories  had begun to  experience  a  declining
     average  selling price. In addition the Company  believed that  alternative
     testing  methods,  including  on-site  testing,  would become  available in
     future years that may make the then existing  forms of  laboratory  testing
     less competitive.  While the Company expected to continue to develop and/or
     evaluate new testing  technologies,  the then  existing  form of laboratory
     testing at MEDTOX  Laboratories was unable to support the carrying value of
     the goodwill generated from the sale of that laboratory to the Company.

     Utilizing an undiscounted  cash flow analysis,  the Company  concluded that
     the carrying  value of the remaining  goodwill  associated  with the MEDTOX
     Laboratories   acquisition   exceeded  the  estimated  future  cash  flows.
     Accordingly,  the Company  recorded a write-off of  $6,016,000  in December
     1996.

     In September 1996, upon the sale of Bioman, the Company recorded a $101,000
     write-off  of the goodwill  associated  with the  original  acquisition  of
     Bioman.

     On January 14, 1998, the Company entered into a Credit  Security  Agreement
     (the Norwest Credit Agreement) with Norwest Business Credit (Norwest).  The
     Company  utilized  $4.5  million of the  proceeds  from the Norwest  Credit
     Agreement  to repay the  outstanding  second  term loan owed to its  former
     lender, Heller Financial, Inc. (Heller).

     The Norwest  Credit  Agreement  consists  of (i) a term loan of  $2,125,000
     bearing interest at prime + 1.25% due January 15, 2001; (ii) an overadvance
     term loan of $700,000  bearing interest at prime + 3% due January 15, 1999;
     (iii) a revolving line of credit of not more than  $6,000,000 or 80% of the
     Company's eligible trade accounts receivable bearing interest at prime + 1%
     due January 15,  2001;  and (iv) a capex note of up to  $1,200,000  for the
     purchase of capital  equipment  for 1998 bearing  interest at prime + 1.25%
     due January 15,  2001.  At December 31, 1998,  $3,095,000  was  outstanding
     under the  revolving  line of credit,  and  $252,000  was  available  to be
     advanced  under the borrowing base formula.  The Norwest  Credit  Agreement
     requires the Company to comply with certain  covenants and maintain certain
     quarterly  financial ratios as to minimum debt service coverage and maximum
     debt to book net worth. It also sets minimum  quarterly net income and book
     net worth  levels  which  restrict  the payment of  dividends.  The Norwest
     Credit  Agreement  is secured by  virtually  all of the  Company's  assets,
     including equipment, general intangibles, inventories, and receivables.

     On May 22,  1998,  the  Company and  Norwest  amended  the  Norwest  Credit
     Agreement (the First  Amendment).  The First Amendment waived the Company's
     noncompliance  with the  minimum  book net  worth  covenant  for the  first
     quarter of 1998.  It also set new minimum book net worth  requirements  for
     each fiscal quarter through January 31, 1999.
<PAGE>

     On November  24,  1998,  the Company and Norwest  again  amended the Credit
     Agreement (the Second  Amendment).  The Second  Amendment  consisted of (i)
     additional  borrowings  of up to the  original  $2,125,000  term  loan  and
     extension of the due date to November 25, 2001; (ii) an additional $300,000
     borrowing  under the  original  overadvance  term loan of  $700,000  and an
     extension  of the due  date to June 1,  1999;  (iii) a capex  note of up to
     $1,000,000 for the purchase of capital  equipment for 1999 and extension of
     the due date to November 25, 2001; (iv) the quarterly  financial  ratios as
     to minimum debt service  coverage and maximum debt to book net worth ratios
     were  modified;  (v) the  quarterly  minimum  net income and book net worth
     levels were adjusted; (vi) a waiver permitting the creation of CMS; (vii) a
     waiver  permitting  the mergers of Precision Drug Testing  Laboratories  of
     America,  Inc., Princeton Drug Testing  Laboratories of America,  Inc., and
     MEDTOX  Diagnostics  into the  Company;  (viii) a waiver  of the  Company's
     noncompliance  with the  minimum  net  income  and  minimum  book net worth
     requirements  for the quarter ended June 30, 1998; and (ix) a waiver of the
     Company's  noncompliance  with the  minimum net  income,  minimum  book net
     worth, and minimum debt service coverage ratio requirements for the quarter
     ended September 30, 1998.

     As of  December  31,  1998,  the  Company  was not in  compliance  with the
     provisions of the minimum debt service coverage ratio,  minimum net income,
     and  minimum  book net worth  covenants  of the Norwest  Credit  Agreement.
     However,  on April  12,  1999,  the  Company  amended  the  Norwest  Credit
     Agreement  effective  April  1,  1999  (the  Third  Amendment).  The  Third
     Amendment  waived  the  Company's  noncompliance  with these  covenants  at
     December 31, 1998 and also  modified the terms of the  financial  covenants
     for 1999. Management is of the opinion the Company can achieve the modified
     financial covenants throughout the course of 1999.  Accordingly,  long-term
     debt  under the  Norwest  Credit  Agreement  has not been  reclassified  as
     current.

     On December 31, 1998, the Company received $175,000 from private placements
     of subordinated  debt. The notes require payment of the principal amount on
     December 31, 2001.  Interest at 12% per annum is paid  semiannually on June
     30 and December  31. In  connection  with the issuance of the  subordinated
     notes,  the Company  issued  warrants to  purchase  8,750  shares of common
     stock,  exercisable  from  December 15, 1999 to December  31,  2001,  at an
     exercise price of $5.00 per share.  The Company has determined the value of
     the warrants at the date of grant to be $27,000.  The value of the warrants
     has been accounted for as additional  paid-in capital and deducted from the
     principal of the subordinated notes as discount on debt issued.

     During the first  quarter  of 1999,  the  Company  received  an  additional
     $400,000 from private  placements of subordinated debt under the same terms
     as the December 1998 debt issuances. In connection with the issuance of the
     subordinated  notes,  the Company issued warrants to purchase 20,000 shares
     of common stock at an exercise price of $5.00 per share.

     Interest paid for all outstanding debt was $599,000, $576,000, and $424,000
     for the years ended December 31, 1998, 1997, and 1996, respectively.

6.   STOCKHOLDERS' EQUITY

     The Board of  Directors  declared  a  one-for-twenty  reverse  stock  split
     effective February 20, 1999. Accordingly, all stock option, warrant, share,
     and per share data  included in this  report have been  restated to reflect
     the reverse split.

     The Company has sold its common stock in various  private  transactions  as
follows:

                          Number         Price
                            of            Per         Net

     1996                11,765         $51.00   $ 600,000

     In January 1996, the Company sold 407 shares of Series A Preferred Stock at
     a price of $50,000 per share.  Each share of Series A  Preferred  Stock was
     convertible  into shares of common stock. The amount of common shares to be
     issued upon the exercise of the conversion right is derived by dividing (i)
     the  purchase  price of one share of Series A Preferred  Stock,  $50,000 by
     (ii) the lower of (x) $2.775 or (y) 75% of the  market  price of the common
     stock on the date the  conversion  right is exercised.  The market price is
     defined  as the daily  average  of the  closing  bid  prices  quoted on the
     American Stock Exchange for the five trading days immediately preceding the
     date the  conversion  right is  exercised.  At December 31,  1998,  all 407
     shares of Series A Preferred Stock had been converted into 1,798,462 shares
     of common stock.

     The market  price of the  Company's  common stock was $70.00 on the date of
     issuance of the Series A Preferred  Stock.  The reduction in the conversion
     price of the Series A  Preferred  Stock from $70.00 to $52.50 per share was
     valued at $6,783,333  and recorded as a preferred  stock dividend to arrive
     at  the  1996  net  loss  available  to  holders  of  common  stock  in the
     calculation of net loss per share in 1996.

     As part of the purchase  price paid by the Company for the  acquisition  of
     MEDTOX Laboratories, the Company issued 125,865 shares of common stock.

     In connection  with the issuance of the common  shares,  the Company agreed
     that if, after the closing date of the MEDTOX Laboratories acquisition, the
     market value of the Company's  common stock  declined  below  approximately
     $39.60 per share, the Company would issue additional shares of common stock
     (Additional Shares) to shareholders of MEDTOX Laboratories who retain their
     shares of common stock at specified  dates  through  November 19, 1997 (the
     Repricing  Dates).  The  following  is a summary of the price  resets,  the
     market price per share used for purposes of calculating  the reset quantity
     of shares, and the quantity of additional shares that were issued in 1997:

     In  addition,  at December 31,  1998,  416,770  shares of common stock were
     reserved for future  issuances  under the stock  option plans  discussed in
     Note 7.

     On September 18, 1998,  the  Company's  Board of Directors  authorized  and
     declared a dividend of one preferred  share  purchase right for each common
     share then  outstanding.  Subsequent  to that date the Company  maintains a
     plan in which one preferred  share  purchase  right (Right) exists for each
     common share of the Company. Each Right entitles its holder to purchase one
     one-hundredth of a share of a new series of junior participating  preferred
     stock at an exercise price of $29.80, subject to adjustment. The Rights are
     exercisable only if a person or group acquires  beneficial  ownership of 20
     percent or more of the Company's outstanding common stock.

7.   STOCK OPTION AND PURCHASE PLANS

     The  Company  has stock  option  plans to provide  incentives  to  eligible
     employees,  officers, and directors in the form of incentive stock options,
     nonqualified  stock  options,  stock  appreciation  rights,  restricted and
     unrestricted  stock  awards,  performance  shares,  and  other  stock-based
     awards. The Compensation Committee of the Board of Directors determines the
     exercise price (not to be less than the fair market value of the underlying
     stock)  at the date of  grant.  Options  generally  become  exercisable  in
     installments  over a period of one to five  years and expire ten years from
     the date of grant.

</TABLE>


     Nonqualified  Stock  Options  - The  shares  of  common  stock  covered  by
     nonqualified  options  are  restricted  as  to  transfer  under  applicable
     securities laws.

     Qualified  Employee  Stock  Purchase  Plan - The  Company  has a  Qualified
     Employee  Stock Purchase Plan (the Purchase Plan) under which all employees
     meeting  certain  criteria may  subscribe to and purchase  shares of common
     stock.  The number of shares of common stock  authorized to be issued under
     the Purchase Plan is 25,000. The subscription price of the shares is 85% of
     the  fair  market  value  of the  common  stock  on the  day  the  executed
     subscription  form is received by the Company.  The purchase  price for the
     shares is the lesser of the  subscription  price or 85% of the fair  market
     value of the shares on the day the right to purchase is exercised.  Payment
     for common stock is made through a payroll deduction plan.

     The Company applies Accounting  Principles Board Opinion No. 25, Accounting
     for Stock Issued to Employees, and related  interpretations,  in accounting
     for its stock-based compensation plan. Accordingly, no compensation expense
     has been recognized for its stock option awards, because the exercise price
     of all options  equals the market price of the stock on the grant date. Had
     compensation  expense for the Company's stock option awards been determined
     based upon their  grant date fair  value  consistent  with the  methodology
     prescribed  under  Statement of  Financial  Accounting  Standards  No. 123,
     Accounting for Stock-Based Compensation,  the Company's net loss applicable
     to common  stockholders  and basic and diluted loss per share applicable to
     common  stockholders  would have been  $2,746,000  and  ($0.95 per  share),
     $87,000 and ($.03 per share),  and  $20,027,000  and ($11.97 per share) for
     1998,  1997, and 1996,  respectively.  The fair value of the options at the
     grant date was estimated using the  Black-Scholes  model with the following
     weighted average assumptions:

                                         1998            1997           1996

     Dividend yield                         0%             0%             0%

     The weighted  average  fair value of options  granted in 1998 was $5.22 per
share.

8.   LEASES

     The Company leases office and research  facilities  from a director under a
     month-to-month  operating  lease.  Rental  payments  to the  director  were
     approximately $122,000, $121,000, and $122,000 for the years ended December
     31, 1998, 1997, and 1996, respectively.
<PAGE>

     The Company leases other offices and facilities and office  equipment under
     certain  operating leases which expire on various dates through March 2002.
     Under the  terms of the  facility  leases,  a pro rata  share of  operating
     expenses and real estate  taxes are charged as  additional  rent.  See also
     Note 9 regarding  restructuring  costs relative to certain facility leases.
     The Company  subleases one of its  facilities to another party whereby that
     party makes payments directly to the lessor.

     As of December 31, 1998,  the Company is obligated for future minimum lease
     payments  (excluding  payments under the leases vacated as part of the 1996
     restructuring  discussed in Note 9) without  regard for  sublease  payments
     under noncancelable leases as follows (in thousands):

     Rent  expense  (including  amounts  for  the  facilities  leased  from  the
     director) amounted to $751,000,  $582,000, and $638,000 for the years ended
     December 31, 1998, 1997, and 1996, respectively.

9.   RESTRUCTURING COSTS

     During 1996, the Company  recorded  restructuring  costs of $2,449,000 as a
     result of the  consolidation of the laboratory  operations of PDLA into the
     laboratory  operations  at  Medtox  Laboratories,  the  sale of the  former
     operations of Bioman, and the reduction of its work force at certain of its
     facilities.  In fiscal  1996,  payments of $646,000  were made  against the
     restructuring reserves.

     In fiscal 1997,  restructuring reserves decreased by $1,017,000 to $786,000
     at December  31,  1997,  due to payments of $620,000  and a decrease in the
     estimate of the required reserve of $397,000 in December 1997.

     In fiscal 1998,  restructuring reserves increased by $369,000 to $1,155,000
     at December  31,  1998,  due to payments of $342,000 and an increase in the
     estimate of the required  reserve of $711,000 in the fourth quarter of 1998
     resulting from  preliminary  unfavorable  court rulings relative to certain
     contingencies originally accrued for in 1996.

10.  INCOME TAXES

     Deferred  income  taxes  reflect the tax effects of  temporary  differences
     between  the  carrying  amounts of assets  and  liabilities  for  financial
     reporting purposes and the amounts used for income tax purposes.

     Significant components of the Company's deferred tax liabilities and assets
are as follows (in thousands):

</TABLE>

     At December  31, 1998,  the Company had net  operating  loss  carryforwards
     (NOLs) of approximately  $35,600,000  which are available to offset taxable
     income  through 2013 and begin to expire in 1999.  For financial  reporting
     purposes,  a valuation  allowance has been recorded to offset  deferred tax
     assets that might not be realized.

     Section 382 of the Internal  Revenue Code restricts the annual  utilization
     of the NOLs  incurred  prior to a change  in  ownership.  Such a change  in
     ownership may have occurred in connection with stock  transactions in 1996,
     and another  change in ownership may have  occurred in connection  with the
     conversion  of Series A  Preferred  Stock in 1997 and 1998.  As a result of
     these changes in ownership,  the future  availability  of the NOL to offset
     taxable income is likely substantially curtailed.

11.  BENEFIT PLANS

     The  Company   has  a  defined   contribution   benefit   plan  that  cover
     substantially  all  employees  who meet  certain  age and length of service
     requirements. Contributions to the plans are at the discretion of the Board
     of  Directors.  The 401(k)  expense for the years ended  December 31, 1998,
     1997, and 1996 was $98,000, $152,000, and $80,000, respectively.

12.  COMMITMENTS AND CONTINGENCIES

     The  Company  is a  defendant  in a suit in Circuit  Court of Cook  County,
     Illinois  to a claim of unpaid  rent  obligations  associated  with an idle
     facility  in  Illinois.   The  Company   answered  the  complaint   denying
     responsibility  for the  obligation.  In December  1998,  the Court granted
     summary  judgment  against the Company on certain  issues  relative to this
     matter.  While the Company  intends to  vigorously  defend this action,  in
     December 1998,  following the summary judgment,  an additional  accrual, as
     discussed in Note 9, was established.

     The Company  has entered a  settlement  agreement  with United  States Drug
     Testing  Laboratories who asserted a claim of patent  infringement  against
     the Company on August 20, 1996.  It was alleged that the Company  infringes
     two patents  allegedly  owned by United  States Drug  Testing  Laboratories
     relating to forensically  acceptable  determinations  of gestational  fetal
     exposure to drugs and other chemical agents.  The Company while denying any
     infringement  has reached a settlement  agreement  with United  States Drug
     Testing  Laboratories  whereby  the  Company  will pay United  States  Drug
     Testing   Laboratories   $17,500  and  issue  United  States  Drug  Testing
     Laboratories 2,500 shares of common stock.

     The Company believes that the probable  outcome of the above  contingencies
     will not materially affect the financial  position or results of operations
     of the Company.

     On January 31, 1997,  the Company filed suit in Federal  District  Court in
     Minnesota  against a majority  shareholder and two former outside directors
     of the Company alleging violation of Section 16b of the Securities Exchange
     Act of 1934 and  seeking  recovery  of more than  $500,000  in  short-swing
     profits. On August 4, 1997, the U.S. District Court granted the defendants'
     Motion to Dismiss the  Company's  complaint,  ruling  that the  defendants'
     conduct did not  constitute  a violation of Section  16(b).  On October 29,
     1997,  the Company  filed an appeal of that  decision to the United  States
     Court of Appeals for the Eighth  Circuit  (Court of  Appeals).  On July 21,
     1998, the Court of Appeals reversed the U.S. District Court's dismissal and
     remanded the case back to the U.S. District Court.

     Under the MEDTOX Laboratories  acquisition  agreements,  the Company may be
     contingently  liable for  certain  tax  liabilities  incurred by the former
     MEDTOX  Laboratories  shareholders.  At  the  present  time,  the  possible
     liability under this agreement is not reasonably  ascertainable because the
     agreement,  as written, is ambiguous and its intent is not clear. Under the
     agreement,  the  obligation,  if any,  on the  part of the  Company  can be
     deferred  under certain  circumstances  and at the present time the Company
     believes this deferral will be available to the Company for the foreseeable
     future.

                             MEDTOX SCIENTIFIC, INC.

         MEDTOX Scientific, Inc., a corporation organized and existing under the
General  Corporation  Law of the State of  Delaware  (the  "Corporation"),  does
hereby certify that:

         The amendment to the  Corporation's  Certificate of  Incorporation  set
forth  in the  following  resolution  approved  by the  Corporation's  Board  of
Directors and stockholders was duly adopted in accordance with the provisions of
section 242 of the General Corporation Laws of the State of Delaware:

         "RESOLVED,  that the Certificate of Incorporation of the corporation be
amended by striking Article FOURTH in its entirety and replacing therefor:

         'FOURTH:  The total  number of  shares of stock  which the  Corporation
shall have  authority  to issue is FOUR MILLION  SEVEN  HUNDRED  FIFTY  THOUSAND
(4,750,000)  shares,  THREE MILLION SEVEN HUNDRED FIFTY THOUSAND  (3,750,000) of
which shall be of a class designated as Common Stock with a par value of FIFTEEN
CENTS ($0.15) per share and ONE MILLION of which shall be a class  designated as
Preferred  Stock with a par value of ONE DOLLAR  ($1.00)  per share.  All or any
part of the authorized  capital stock of the Corporation may be issued and sold,
from time to time by the  corporation,  without further action by  stockholders,
for such  consideration  (but not less than the par value  thereof)  and to such
persons and on such terms and  conditions as may, from time to time, be fixed or
determined  by  the  Board  of  Directors.  The  voting  powers,   designations,
preferences, and relative,  participating,  optional or other special rights and
the qualifications, limitations or restrictions thereof, of the classes of stock
of the corporation which are fixed by this Certificate of Incorporation, and the
authority  vested in the Board of Directors to fix by  resolution  or resolution
providing  for the issue of  Preferred  Stock the voting  powers,  designations,
preferences and relative,  participating,  optional or other special rights, and
the  qualifications,  limitations  or  restrictions  thereof,  of the  shares of
Preferred Stock which are not fixed by the Certificate of Incorporation,  are as
follows:

         1. The  Preferred  Stock may be issued from time to time in one or more
series, each such series to have such distinctive designation or title as may be
fixed by the Board of  Directors  prior to the  issuance of any shares  thereof.
Each such series may differ from every other series  already  outstanding as may
be determined  from time to time by the Board of Directors prior to the issuance
of any shares thereof, in any or all of the following, but in other, respects:

                  (a) The rate of dividend which the Preferred Stock of any such
series shall be entitled to receive,  whether the dividends of such series shall
be cumulative or non-cumulative and, if such dividends shall be cumulative,  the
date from which they shall be cumulative.

                  (b) The right or  obligation,  if any, of the  corporation  to
redeem  shares of  Preferred  Stock of any series and the amount per share which
the  Preferred  Stock of any such series shall be entitled to receive in case of
the redemption thereof, and the right of the corporation, if any, to reissue any
such shares after the same shall have been redeemed.
<PAGE>

                  (c) The amount per share which the Preferred Stock of any such
series  shall be  entitled  to  receive  in case of the  voluntary  liquidation,
distribution or sale of assets, dissolution or winding up of the corporation, or
in  case  of the  involuntary  liquidation,  distribution  or  sale  of  assets,
dissolution or winding up of the corporation.

                  (d) The right,  if any, of the holders of  Preferred  Stock of
any such  series to convert  the same into other  classes of stock and the terms
and conditions of such conversion.

                  (e) The voting  power,  if any,  of the  holders of  Preferred
Stock of any such  series,  and the terms and  conditions  under  which they may
exercise such voting power.

     (f) The terms of the sinking fund or fund of similar nature,  if any, to be
provided for the Preferred Stock of any such series.

         The  description  of terms of the  Preferred  Stock of each  series  in
respect of the foregoing  particulars shall be fixed and determined by the Board
of  Directors  by  appropriate  resolution  at or  prior  to  the  time  of  the
authorization of the issue of the original shares of each such series.

         2. In case the stated dividends and the amounts payable on liquidation,
distribution or sale of assets, dissolution or winding up of the corporation are
not paid in full, the  stockholders  of all series of the Preferred  Stock shall
share ratably in the payment of dividends,  including accumulations,  if any, in
accordance  with the same which would be payable on such shares if all dividends
were declared and paid in full and in any  distribution  of assets other than by
way of  dividends,  in  accordance  with the sums which would be payable on such
distribution if all sums payable were discharged and paid in full.

         3. The  holders of the  Preferred  Stock  shall be entitled to receive,
when and as declared by the Board of Directors,  out of funds legally  available
therefor,  preferential  dividends in cash at, but not exceeding the annual rate
fixed for each particular  series.  The holders of the Preferred Stock shall not
be entitled to receive any dividends thereon other than dividends referred to in
this Subdivision 3.

         4. So long as any of the  Preferred  Stock remains  outstanding,  in no
event shall any dividend whatever, whether in cash or other property (other than
shares of Common Stock),  be paid or declared or any distribution be made on the
Common Stock, nor shall any shares of the Common Stock be purchased,  retired or
otherwise  acquired for a consideration  by the corporation  unless (a) the full
dividends  of the  Preferred  Stock  for all  past  dividend  periods  from  the
respective date or then current  quarter-yearly  dividend period shall have been
paid or declared and a sum set apart sufficient for the payment thereof, and (b)
if at any time he corporation is obligated to retire shares of any series of the
Preferred  Stock pursuant to a sinking fund or a fund of a similar  nature,  all
arrears, if any, in respect of the retirement of the Preferred Stock of all such
series shall have been made good.  Subject to the foregoing  provisions  and not
otherwise,  such  dividends  (payable  in cash,  stock or  otherwise)  as may be
determined  by the Board of  Directors  may be  declared  and paid on the Common
Stock from time to time out of the remaining  funds of the  corporation  legally
available therefor, and the Preferred Stock shall not be entitled to participate
in any such dividend, whether payable in cash, stock or otherwise.

         5. In the event of any  liquidation,  distribution  or sale of  assets,
dissolution or winding up of the corporation,  whether voluntary or involuntary,
before any distribution or payment shall be made to the holders of Common Stock,

<PAGE>

the holders of the  Preferred  Stock of each series shall be entitled to be paid
in cash the  applicable  liquidation  price per  share  fixed at the time of the
original authorization of issuance of shares of such respective series, together
with a sum in the case of each share of the  Preferred  Stock,  computed  at the
annual  dividend  on such share  because  cumulative  to the date fixed for such
distribution or payment date paid thereon.  If such payment shall have been made
in full to the holders of the Preferred Stock, the remaining assets and funds of
the  corporation  shall be  distributed  among the  holders of the Common  Stock
according to their respective shares.

         6. Subject to the powers, preferences and rights and the qualification,
limitations  and  restrictions  thereof,  with  respect to each class of capital
stock of the  corporation  having any  preference  or  priority  over the Common
Stock,  the  holders  of the Common  Stock  shall  have and  possess  all rights
appertaining  to capital stock of the  corporation.  Holders of Common Stock may
not act by written consent without a meeting.'"
