INFORMATION AND FINANCIAL  STATEMENTS AND NOTES  THERETO APPEARING ELSEWHERE  IN
THIS PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE, INCLUDING INFORMATION UNDER
"RISK  FACTORS," AND IN THE INFORMATION  AND DOCUMENTS INCORPORATED BY REFERENCE

UNCERTAINTIES,  INCLUDING,  BUT NOT  LIMITED TO,  THE RISKS  SET FORTH  IN "RISK
FACTORS." ACTUAL RESULTS MAY DIFFER MATERIALLY.
 
                                  THE COMPANY
 
    AccuMed  International,   Inc.  ("AccuMed"   or  the   "Company")   designs,
manufactures  and  markets diagnostic  and screening  products for  the clinical
diagnostic laboratory,  pharmaceutical  and veterinary  markets.  The  Company's
products  use innovative proprietary technology  designed to improve quality and
productivity and reduce costs in the cytopathology and microbiology  laboratory.
The  Company's cytopathology products provide  automated support and enhancement
of the human screener in the analysis of cytopathology specimens. The  Company's
initial products for the cytopathology laboratory market are the AcCell 2000 and
the  AcCell 2001  automated slide handling  and microscopy  workstations for the
analysis of  cervical Pap  smears (collectively,  the "AcCell  2000/2001").  The
Company  is developing  a set of  related products, including  the TracCell 2000
specimen mapping  workstation,  designed to  work  in concert  with  the  AcCell
2000/2001  to offer  the cytopathology laboratory  a family  of high performance
tools that provide comprehensive support  during initial critical phases of  the
Pap   smear  analysis  process.  The  Company  has  recently  granted  exclusive
distribution rights in the Western Hemisphere  for the AcCell 2000/2001 and  the
TracCell  2000 to  Olympus America Inc.  ("Olympus"). Marketing  of the TracCell
2000 is subject to  additional testing and, for  the U.S. market, FDA  clearance
under a 510(k) Notification. The Company also offers the microbiology laboratory
a  variety of FDA-cleared products for the identification and minimum inhibitory
concentration ("MIC/ID") testing of bacteria suspected of causing infections and
their susceptibility to antibiotics under the tradenames Sensititre and  Alamar.
AccuMed  is  developing  a  low  cost  Kirby-Bauer  reading  instrument  for the
microbiology market and  is researching  a potential new  MIC/ID testing  system
combining certain of the Company's proprietary technologies.
 
    The Pap smear is currently the most widely-used screening test for the early
detection  of cancer in the United States.  It is estimated that laboratories in
the U.S. alone will process  over 55 million Pap smears  in 1996, with over  120
million  processed worldwide. Although cervical cancer is one of the most common
cancers afflicting women throughout the world,  survival rates can reach 90%  if
detected  early.  Although  the conventional  manual  Pap smear  test  is highly
effective,   the   test   and   process   has   limitations,   including   human
cytotechnologist  error  due  to  high  volumes,  habituation  and  fatigue, and
burdensome administrative requirements. False negative Pap smear diagnoses rates
range from  between  5% to  30%,  and both  false  negative and  false  positive
diagnoses  lead to significant  liability issues to  the laboratory and possible
health issues to the patient, while at the same time adding significant cost  to
the  process. The AcCell system directly addresses these issues by eliminating a
large portion of the manual work ancillary to slide analysis, guaranteeing  100%
slide review and automatically recording and reporting what has been done on the
AcCell data management system.
 
   
    The  Company's cytopathology products are designed to improve the quality of
cell analysis, increase accuracy and productivity in the laboratory, and  reduce
the  time and costs associated with  analysis, but without requiring significant
changes from standard  laboratory practice.  Rather than  developing costly  and
risky  fully automated primary  screening systems that eliminate  the need for a
trained cytotechnologist, the  Company is focused  on providing a  comprehensive
family  of  proprietary,  technologically-advanced,  application-driven products
offering seamless support of medical professionals in the analysis and diagnosis
of Pap smears and  other cell samples. Initially  applied to Pap test  analysis,
the  AcCell system is expected to have a broad range of cytopathology, pathology
and histology applications.
    
 
                                       4

   
    The Company's microbiology division focuses on developing, manufacturing and
marketing in vitro diagnostic tests for the clinical laboratory, veterinary  and
pharmaceutical  markets. The  Company markets, and  is developing,  a variety of
proprietary MIC/ID  testing  products, both  manual  and automated,  focused  on
testing for bacterial infections. AccuMed's microbiology product lines include a
series of disposable test kits and a wide range of automated instruments used to
identify   infectious   organisms,   such  as   bacteria,   and   determine  the
susceptibility of such organisms to  antimicrobial agents, such as  antibiotics.
The  use of MIC/ID testing by  hospitals and laboratories assists physicians and
other health  care professionals  in determining  the most  effective course  of
treatment  earlier and more efficiently, potentially shortening patient hospital
stays, resulting  in more  accurate diagnoses  and reducing  overall  healthcare
costs.  For the three months ended March 31, 1996 the Company generated revenues
of $1,179,000 from sales of microbiology products.
    
 
    The Company  and  its  predecessor companies  have  consistently  pursued  a
strategy  of developing  or acquiring early  detection products  that reduce, or
potentially reduce,  overall healthcare  costs  while enhancing  or  maintaining
current levels of effectiveness. The Company believes that the current pressures
in  the healthcare  industry for  reduced costs  and increased  efficiencies are
better addressed by products that work within and enhance established practices.
Products that seek to revolutionize established practices often face  regulatory
and  market acceptance hurdles that are difficult if not impossible to overcome.
The Company  is also  focused on  integrated product  designs that  the  Company
believes  are demanded  by a market  that seeks individualized  products and the
ability to  expand  product  capability  as  the  customer's  business  changes.
AccuMed's  objective is to establish the AcCell system as the premier microscopy
workstation for the primary screening of Pap smears, exploit other  applications
for  the AcCell technology  such as histology and  pathology laboratory work and
enhance its position  in the MIC/ID  testing market through  development of  new
products  based on  proprietary technology.  The key  elements of  the Company's
strategy include  (i) continuing  to  establish the  AcCell system  through  OEM
agreements  with  major microscope  manufacturers,  such as  the  agreement with
Olympus already in place, (ii)  focusing on international market  opportunities,
(iii)  enhancing  the  Accell system  through  research and  development  of new
products, (iv) establishing a recurring  revenue base by charging TracCell  2000
users  "by  the test",  (v) integrating  the Company's  proprietary microbiology
technologies into new MIC/ID products,  (vi) continuing to seek out  acquisition
candidates  with compatible  technologies and (vii)  setting up  new channels of
sales and distribution.
 
    AccuMed is  headquartered at  900 N.  Franklin Street,  Suite 401,  Chicago,
Illinois 60610, with additional facilities in Westlake, Ohio and East Grinstead,
Sussex,  England. Previously, the Company was incorporated under the laws of the
State of California as "Alamar Biosciences, Inc." On December 29, 1995, AccuMed,
Inc., an  Illinois  corporation, merged  (the  "Merger") with  and  into  Alamar
Biosciences,  Inc. and the  surviving entity was  renamed AccuMed International,
Inc. and reincorporated  under Delaware  law. The Company  has one  wholly-owned
subsidiary, AccuMed International, Ltd. ("AccuMed U.K." or "Sensititre")

                                  RISK FACTORS
 
    THE  SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK, INCLUDING, BUT
NOT NECESSARILY LIMITED TO, THE  RISK FACTORS DESCRIBED BELOW. EACH  PROSPECTIVE
INVESTOR  SHOULD CAREFULLY CONSIDER  THE FOLLOWING RISK  FACTORS INHERENT IN AND
AFFECTING THE  BUSINESS  OF THE  COMPANY  AND  THIS OFFERING  BEFORE  MAKING  AN
INVESTMENT  DECISION. THE STATEMENTS THAT ARE NOT HISTORICAL FACTS OR STATEMENTS
OF CURRENT STATUS  CONTAINED IN THIS  PROSPECTUS ARE FORWARD-LOOKING  STATEMENTS
THAT  INVOLVE RISKS AND UNCERTAINTIES INCLUDING, BUT NOT LIMITED TO, THE FACTORS
SET FORTH BELOW. ACTUAL RESULTS MAY DIFFER MATERIALLY.
 
    LIMITED  RELEVANT   OPERATING   HISTORY;   SIGNIFICANT   OPERATING   LOSSES;
ACCUMULATED  DEFICIT; SUBSTANTIAL COSTS  OF INTEGRATION AND  CONSOLIDATION.  The
Company's predecessor was formed in 1988  and was engaged primarily in  research
and  development  of  microbiology  products  until  early  1994.  The Company's
predecessor never realized any significant revenues from product sales. AccuMed,
Inc., which was merged  into the Company in  December 1995, was incorporated  in
February  1994  and  in  February  1995  acquired  the  Sensititre  microbiology
business. Until such acquisition, AccuMed,  Inc. had no revenues and  operations
consisted of a limited amount of research and development. Accordingly, although
the  Sensititre business had  a significant operating  history and revenues from
sales, AccuMed, Inc., as a separate  entity, had very limited operating  history
prior  to the Merger. Upon consummation of  the Merger on December 29, 1995, the
operations of the  Company and  AccuMed, Inc.  were combined  and the  resulting
company  began to  develop, manufacture and  sell the Alamar  and the Sensititre
microbiology products and the AccuMed cytopathology products. Thus, the combined
Company has a  limited relevant operating  history upon which  an evaluation  of
it's  prospects can be made.  Such prospects must be  considered in light of the
risks, expenses and  difficulties frequently encountered  in establishing a  new
business  in a continually evolving industry with an increasing number of market
entrants and  intense  competition  and the  risks,  expenses  and  difficulties
encountered  in the shift from development  to commercialization of new products
based on innovative technology.
 
    The Company has incurred significant operating losses in each fiscal quarter
since its inception. For the  years ended September 30,  1994 and 1995, and  the
three months ended December 31, 1995 and March 31, 1996, the Company's operating
losses  were  approximately $3,146,000,  $3,707,000, $5,662,000  and $2,649,000,
respectively. The costs  of integrating  and consolidating  the recently  merged
companies  as  a  single  enterprise  have  been  substantial  and  account  for
approximately $4,000,000 and $3,500,000 of the losses for the three months ended
December 31, 1995 and March  31, 1996, respectively. As  of March 31, 1996,  the
Company had an accumulated deficit of approximately $25,410,000. Such losses are
expected  to continue for the foreseeable future until such time, if any, as the
Company is able  to attain sales  levels sufficient to  support its  operations.
There  can  be  no  assurances  that  the  Company  will  be  able  to implement
successfully its operating strategy, generate increased revenues or ever achieve
profitable operations.
 
    SIGNIFICANT CAPITAL  REQUIREMENTS;  POSSIBLE NEED  FOR  ADDITIONAL  CAPITAL;
SUBSTANTIAL  ACCOUNTS PAYABLE.  The Company  intends to expend substantial funds
for  research  and  product  development,  expansion  of  sales  and   marketing
activities,  expansion of manufacturing  capacity and other  working capital and
general corporate  purposes.  Although  the  Company  believes  that  internally
current  resources and generated funds will  be sufficient to fund the Company's
projected operations through the  next 12 months, no  assurances to that  effect
can  be  given. The  Company's future  liquidity  and capital  requirements will
depend upon numerous  factors, including the  costs and timing  of expansion  of
manufacturing  capacity, the costs, timing and  success of the Company's product
development efforts, the costs  and timing of expansion  of sales and  marketing
activities,  the extent  to which the  Company's existing and  new products gain
market acceptance, competing technological and market developments, the progress
of commercialization efforts of the  Company's distributors, the costs  involved
in  preparing, filing, prosecuting, maintaining,  enforcing and defending patent
claims  and  other  intellectual   property  rights,  developments  related   to
regulatory and third party reimbursement matters and CLIA, and other factors. In
the  event  that  additional  financing  is  needed,  the  Company  may  seek to
 
                                       7

raise additional  funds  through  public  or  private  financing,  collaborative
relationships  or other arrangements.  The Company currently  has no commitments
with respect to sources of additional financing, and there can be no  assurances
that any such financing sources, if needed, would be available to the Company or
that  adequate funds  for the Company's  operations, whether  from the Company's
revenues, financial markets, collaborative or other arrangements with  corporate
partners  or  from other  sources, will  be  available when  needed or  on terms
attractive to  the  Company. The  failure  of  the Company  to  obtain  adequate
additional  financing may  require the Company  to delay, curtail  or scale back
some or  all of  its  research and  development  programs, sales  and  marketing
efforts,  manufacturing operations,  clinical studies  and regulatory activities
and, potentially,  to  cease its  operations.  Moreover, the  inability  of  the
Company  to  grant  licenses  to  third  parties  to  commercialize  products or
technologies that the Company would otherwise  develop itself, and the terms  of
such  licenses may be less favorable than if the Company were negotiating from a
stronger position.  Any  additional  equity financing  may  involve  substantial
dilution to the Company's then-existing stockholders.
 
   
    Of  the approximately  $2,146,000 of  accounts payable  as of  May 31, 1996,
approximately $1,690,000 represent  amounts payable  for over  30 days.  Amounts
owed  to various vendors and  suppliers may be subject to  late charges of up to
approximately 1.5%  per  month.  If  the Company  is  unable  to  increase  cash
resources,  significant  demand  for  payment  of  payables  in  excess  of cash
resources could cause the Company  to liquidate assets, issue additional  equity
securities, curtail existing programs or make other arrangements that could have
a  material adverse effect  on the business, financial  condition and results of
operations of the Company.
    
 
    PROTECTION OF  INTELLECTUAL PROPERTY.   The  Company holds  a United  States
patent,  and has received a notice of intent to grant a related European patent,
with respect to a portion of the Alamar microbiology technology. The Company has
obtained licenses  on  several  United  States and  foreign  patents  and  other
intellectual property rights regarding aspects of the technology embodied in the
Sensititre  product line and  in March 1996  entered into a  letter of intent to
acquire certain image  analysis patents  from Accuron  Corporation. The  Company
owns, or has been assigned, six United States patent applications covering blood
cultures,  and certain technologies embodied in the AcCell and TracCell systems.
During 1996, the Company has applied for eight additional United States  patents
relating  to the optical imaging technology. None of such applications have been
granted as of the date  of this Prospectus and there  can be no assurances  that
any  such patent applications will result in issued patents. The Company may, in
the future,  file  additional patent  applications;  however, there  can  be  no
assurances  that the  Company will  be successful  in obtaining  approval of any
future patent applications it files with respect to its technologies.
 
    There  can  be  no  assurances  that  the  aforementioned  patents,   patent
applications  and licenses  will adequately  protect the  Company from potential
infringers. Such  patents,  patent  applications and  licenses  may  cover  only
portions  of the  Company's technologies.  Other portions  may be  in the public
domain or protectable only  under trade secret laws.  In addition, since  patent
applications in the United States are maintained in secrecy until patents issue,
and  since publications  of discoveries in  the scientific  or patent literature
tend to lag behind actual discoveries  by several months, the Company cannot  be
certain that the Company or the original patent application filer, was the first
creator  of  inventions  covered by  pending  patent applications  or  that such
companies were the first to file patent applications for such inventions.
 
    From late 1994 until early 1996, the  Company was party to patent and  trade
secret  litigation both asserting  and defending its rights  relating to part of
the Alamar microbiology technology covered in its existing United States patent.
Despite the successful resolution of such litigation, there can be no assurances
that the Company will  not become a party  to future litigation involving  other
parties in connection with its intellectual property rights.
 
                                       8

    The Company also relies for protection of its intellectual property on trade
secret  law and nondisclosure and confidentiality agreements with its employees,
consultants, distributors, researchers and advisors. There can be no  assurances
that  such agreements will provide meaningful protection for the Company's trade
secrets or  proprietary  know-how  in  the event  of  any  unauthorized  use  or
disclosure  of such  trade secrets or  know-how. In addition,  others may obtain
access to, or independently develop, technologies or know-how similar to that of
the Company.
 
    The Company's success will also depend on its ability to avoid  infringement
of  patent or other proprietary rights of  others. The Company is not aware that
it is  infringing  any  such  rights  of a  third-party,  nor  is  it  aware  of
proprietary  rights of others for which it  will be required to obtain a license
in order to develop its products. However,  there can be no assurances that  the
Company is not infringing proprietary rights of others, or that the Company will
be able to obtain any technology licenses it may require in the future.
 
    DELAYED  OR UNSUCCESSFUL PRODUCT DEVELOPMENT.   The Company will be required
to  undertake  time-consuming  and   costly  development  activities  and   seek
regulatory  approval for these new products. There can be no assurances that the
Company will  not  experience  difficulties  that could  delay  or  prevent  the
successful  development, introduction and marketing  of these new products, that
regulatory clearance or approval of these or any new products will be granted by
the FDA on a timely basis, if at  all, or that the new products will  adequately
meet  the requirements  of the applicable  market or  achieve market acceptance.
Although the Company believes that the  TracCell 2000 will require a  pre-market
clearance under Section 510(k) ("510(k)") of the Federal Food, Drug and Cosmetic
Act  of 1938, as amended, for marketing in the United States, a requirement that
the Company file a pre-market approval ("PMA") application for the product would
significantly delay the Company's ability to market such test and  significantly
increase  the costs of development. The  Company believes that the TracCell 3000
may require a PMA. The Company's growth and profitability will depend, in  part,
upon  its  ability to  complete development  of  and successfully  introduce new
products including  the  TracCell 2000  and  the TracCell  3000.  The  Company's
proposed  TracCell 3000 mapping system  is in an early  stage of development and
there can  be  no  assurances  that  it  will  be  successfully  developed.  The
completion  of the  development of  the Company's  cytopathology products remain
subject to all the risks associated  with the commercialization of new  products
based  on innovative  technologies, including  unanticipated technical  or other
problems  and  the  possible  insufficiency  of  the  funds  allocated  for  the
completion  of such development, which  could result in a  change in the design,
delay in  the development,  or abandonment  of such  applications and  products.
Consequently,   there  can  be   no  assurances  that   the  Company's  proposed
cytopathology products will be successfully  developed or manufactured, or  that
if developed and manufactured, that such products will meet price or performance
objectives,  be  developed on  a timely  basis or  prove to  be as  effective as
competing products.  The inability  to successfully  complete development  of  a
product  or  application  or  a determination  by  the  Company,  for financial,
technical or  other reasons,  not  to complete  development  of any  product  or
application, particularly in instances in which the Company has made significant
capital expenditures, could have a material adverse affect on the Company.
 
    Pursuant  to a  Research and Development  Agreement between  the Company and
RADCO Ventures, Inc.,  the Company  and RADCO are  attempting to  develop a  new
automated   microbiology   product   line   combining   Sensititre   and  Alamar
technologies. The Company is also developing  a new microbiology system for  the
susceptibility  market segment to automatically analyze  the zone size using the
disk diffusion  ("Kirby Bauer")  method.  If such  development projects  do  not
result  in one  or more  commercially viable  products obtaining  FDA pre-market
approval, the Company  may reassess its  business strategy with  respect to  the
Microbiology  Division. Such reassessment could lead to changes in the Company's
overall business plan,  including the relative  allocation of resources  between
the  Microbiology Division and Cytopathology  Division and the relative emphasis
on current, as well as future, products in each division.
 
    LIMITED SALES, MARKETING  AND DISTRIBUTION EXPERIENCE;  DEPENDENCE ON  THIRD
PARTY  DISTRIBUTORS.  In order for the  Company to increase revenues and achieve
profitability, the Company's products, particularly
 
                                       9

its  cytopathology  products,  must  achieve  a  significant  degree  of  market
acceptance.  The Company has  only limited experience  marketing and selling its
cytopathology  products.  The  Company  intends  to  distribute  these  products
primarily  through  a  limited number  of  distributors. [The  Company  has only
recently  entered  into  an  OEM   distribution  arrangement  with  a   national
distributor,  Olympus.  The Company  may be  required  to enter  into additional
distribution  arrangements  in  order  to  achieve  broad  distribution  of  its
products.  There can be no  assurance that the Company  will be able to maintain
the recently  established distribution  relationship with  Olympus or  that  the
Company  will be  able to enter  into and maintain  arrangements with additional
distributors on a timely basis,  if at all. The  Company will be dependent  upon
these  distributors to assist it in  promoting market acceptance of its products
and creating  demand  for the  Company's  products. The  risks  associated  with
dependence  upon distributors will be exacerbated  by the Company's intention to
rely on a limited number  of distributors, with the  result that sales to  these
distributors  will account for a significant  portion of the Company's revenues.
There can  be  assurance  that  these distributors  will  devote  the  resources
necessary  to provide effective  sales and marketing support  to the Company. In
addition, the Company's distributors may give higher priority to the products of
other medical  suppliers, thus  reducing  their efforts  to sell  the  Company's
products.  If the Company  is unable to  establish appropriate arrangements with
distributors or  if the  Company's distributors  become unwilling  or unable  to
promote,  market  and  sell  its  products,  the  Company's  business, financial
condition and results of operations would be materially adversely affected.
 
    GOVERNMENT REGULATION.  The  Company's products and manufacturing  processes
are subject to extensive regulation by state and federal agencies, including the
United  States Food and Drug Administration  (the "FDA") and comparable agencies
in certain states  and other  countries. United  States regulatory  requirements
promulgated  under the  Federal Food,  Drug, and  Cosmetic Act  (the "FD&C Act")
provide that many  of the Company's  products may not  be shipped in  interstate
commerce  without prior authorization from the  FDA. Such authorization is based
on a review of the products'  safety and effectiveness for their intended  uses.
The Company's products which require FDA authorization prior to marketing may be
authorized  by the FDA for marketing either pursuant to a premarket notification
under Section 510(k) of  the FD&C Act (a  "510(k) Notification") or a  premarket
approval  ("PMA"). The  process of obtaining  FDA and  other required regulatory
clearances  or  approvals  can  be  time-consuming,  expensive  and   uncertain,
frequently  requiring several years from the  commencement of clinical trials to
the receipt of regulatory approval.
 
    A 510(k) Notification,  among other  things, requires an  applicant to  show
that  its  products  are  "substantially  equivalent"  in  terms  of  safety and
effectiveness to existing products which are currently permitted to be marketed.
An applicant  is permitted  to begin  marketing a  product as  to which  it  has
submitted a 510(k) Notification at such time as the FDA issues a written finding
of  "substantial equivalence." Requests for additional information may delay the
market introduction  of certain  of an  applicant's products  and, in  practice,
initial  approval of products can take substantially longer than the statutorily
prescribed period of 90 days.
 
    A PMA consists of information  sufficient to establish independently that  a
device  is safe and  effective for its  intended use. A  PMA application must be
supported by extensive data, including  preclinical and clinical trial data,  to
demonstrate  the  safety  and  efficacy  of the  device  for  the  intended uses
specified in the PMA application. By statute, the FDA is required to respond  to
a  PMA within 180  days from the  date of its  submission, however, the approval
process usually takes substantially  longer. Commercial distribution in  foreign
countries  is also subject  to regulatory requirements and  no assurances can be
given that the Company can obtain the required regulatory approvals on a  timely
basis, or at all.
 
    Regulatory approvals, if granted, may include significant limitations on the
intended  uses  for which  a  product may  be  marketed. FDA  enforcement policy
strictly prohibits the promotion by the Company, and any of its distributors, of
approved medical devices for off-label uses. In addition, product approvals  may
be  withdrawn for failure to comply  with regulatory standards or the occurrence
of unforeseen problems following initial marketing.
 
                                       10

    The TracCell 2000 mapping  system, currently under  development and not  yet
marketed,  will require FDA approval prior to  marketing in the United States At
the present time, it is  the opinion of management that  a full PMA will not  be
required  for this mapping device and  that the 510(k) Notification process will
be applicable. There  can be  no assurances  that the  Company will  be able  to
utilize a 510(k) Notification rather than a full PMA process or that the Company
will  receive FDA marketing approval for such product or, if received, that such
approval will not be withdrawn. Marketing  of the TracCell 2000 mapping  system,
if  developed, outside of  the United States  will not require  FDA clearance or
approval, but other regulatory  bodies may submit  the technology to  additional
testing.
 
    The  AcCell 3000, currently in the initial stages of development, may not be
sold in  the United  States unless,  and  until, the  Company has  obtained  FDA
approval  of a PMA  submission. Management estimates that  the entire process of
receiving pre-market approval of  the complete system could  take more than  two
years after submission of initial clinical data. There can be no assurances that
the  Company  will  receive  FDA  marketing approval  for  such  product  or, if
received, that such approval will not be withdrawn. Marketing of the AcCell 3000
outside of the  United States will  not require FDA  clearance or approval,  but
other regulatory bodies may submit the technology to additional testing.
 
    The  Company  has  secured  the  services  of  an  independent  devices  and
diagnostics consulting company  to guide the  process of design,  implementation
and  monitoring  of  field  trials and  submission  of  documentation  for these
cytopathology products to the FDA.
 
    Marketing of the  Company's minimum inhibitory  concentration/identification
("MIC/ID") microbiology products in the United States requires the submission to
the  FDA of a 510(k) Notification. With  respect to the Company's Alamar product
line, 510(k)  Notifications must  be  filed and  cleared  with respect  to  each
antibiotic  used. To date,  the Company has  submitted 510(k) Notifications, and
obtained findings of "substantial equivalence," for 32 antibiotics commonly used
to fight "gram  negative" bacteria  and 21  antibiotics commonly  used to  fight
"gram  positive" bacteria. The Company has also received marketing clearance for
four separate  510(k)  Notifications with  respect  to the  READar  system.  The
Company   may  submit  applications  to  add  individual  antibiotics  to  those
previously cleared, as the market warrants. However, there can be no  assurances
that clearances will continue to be obtained.
 
    The  Company is developing a new  microbiology system for the susceptibility
market segment to  automatically analyze  the zone  size using  the Kirby  Bauer
method.  The Company licensed  the software algorithm  technology from a Spanish
firm and will integrate the software into the hardware developed by the Company.
The complete system will require submission of a 510(k) Notification. There  can
be no assurances that the Company can develop the hardware nor that the licensed
software  is adequate to submit  a 510(k) Notification or  that the Company will
receive the  FDA  marketing  clearance.  Marketing of  the  new  disk  diffusion
product,  if  developed, outside  the  United States  will  not require  any FDA
submissions, clearances or approvals, but other regulatory bodies may submit the
technology to additional testing.
 
    Pursuant to a Research and Development Agreement with RADCO Ventures,  Inc.,
a  research  and  development  company  ("RADCO"),  RADCO  and  the  Company are
attempting to develop a new automated microbiology product line using Sensititre
and Alamar technologies. Such a product will require the submission of a  510(k)
Notification. Management estimates that the entire process of receiving approval
of  the  complete system  could take  up to  12 months  after the  submission of
initial clinical data. There can be no assurances that the Company will  receive
FDA  marketing approval for such  a product or, if  received, that such approval
will not be withdrawn. Marketing of the new automated microbiology product  line
outside  the United States  will not require any  FDA submissions, clearances or
approvals, but other regulatory bodies  may submit the technology to  additional
testing.
 
    The  Company also  intends to seek  ISO 9001  registration, an international
manufacturing quality standard,  and to seek  the "CE" mark  for its AcCell  and
TracCell  products. The CE mark  is recognized by countries  that are members of
the  European   Union   and   the   European   Free   Trade   Association   and,
 
                                       11

effective in 1998, will be required to be affixed to all medical devices sold in
the  European  Union. The  AcCell  2000/2001 successfully  completed  all safety
evaluations required to obtain UL, CSA and international certifications on  June
18,  1996.  Compliance  testing  against FCC  emissions  standards  and  the EMC
Directive was initiated on June 19, 1996 and is expected to be completed  before
August  1, 1996. The AcCell  2000/2001 is expected to  be certified as complying
with CE Mark requirements upon completion of this process. No assurances can  be
given  that the Company will obtain the  CE mark its AcCell or TracCell products
or satisfy ISO 9001 standards, or that any product which the Company may develop
or commercialize will obtain the  CE mark, or will be  able to obtain any  other
required regulatory clearance or approval on a timely basis, or at all.
 
    There can be no assurances that the Company will be able to obtain necessary
regulatory  approvals or clearances in the United States, or internationally, on
a timely basis, or  at all. Delays  in receipt of, or  failure to receive,  such
approvals   or  clearances,  the  loss   of  previously  received  approvals  or
clearances, or failure to comply with existing or future regulatory requirements
would have  a  material adverse  effect  on the  Company's  business,  financial
condition and results of operations.
 
    In   addition,  the  Company   is  subject  to   certain  FDA  registration,
record-keeping and  reporting requirements,  is obligated  to follow  FDA  "Good
Manufacturing  Practices"  ("GMP") regulations  and is  subject to  periodic FDA
inspection.  The  manufacturing  facility  used  to  manufacture  the  Company's
microbiology kits currently meets applicable GMP guidelines and FDA regulations.
The Company's cytopathology manufacturing facility has been designed to meet GMP
standards,  although such  compliance is not  required and the  facility has not
been audited  for compliance.  There can  be no  assurances, however,  that  the
facilities  used to manufacture the Company's products will continue to meet GMP
guidelines. Future changes in regulations  or enforcement policies could  impose
more  stringent  requirements  on  the  Company,  compliance  with  which  could
adversely affect the Company's business.
 
    UNCERTAINTY OF MARKET  ACCEPTANCE AND INITIAL  HIGHER COST OF  CYTOPATHOLOGY
PRODUCTS.   The  Company has  generated limited  revenues from  the sale  of its
cytopathology products to date. The Company's success, growth and  profitability
will  depend on market acceptance of the AcCell 2000/2001 and the TracCell 2000,
if approved for marketing by the FDA, for use in connection with cervical cancer
screening by clinical laboratories and health care providers. Market  acceptance
will  depend on the Company's ability to demonstrate to these parties that there
are limitations  associated with  conventional patient  data management  of  Pap
smear samples, slide handling and mapping, and documentation of slide review and
that  the Company's  products can  substantially mitigate  these shortcomings by
increasing efficiency, diagnostic accuracy and  documenting the scope of  sample
review.  The initial cost of equipping  a clinical laboratory with the Company's
products for use in  connection with cervical cancer  screening will increase  a
laboratory's equipment expenditures. There can be no assurances that the Company
can  demonstrate  to such  parties that  the higher  cost of  equipping existing
laboratories with  the  AcCell 2000/2001  and  TracCell 2000,  if  approved  for
marketing  by the FDA,  will be offset  by a reduction  in costs associated with
increased efficiency and  decreased malpractice liability  risks resulting  from
more  accurate  diagnostics and  better  document slide  review  procedures. The
Company believes that many clinical laboratories offer Pap tests at lower  gross
margins  than other tests in  order to receive orders  for other, higher margin,
laboratory tests.  As  a  result,  clinical laboratories  may  be  reluctant  or
unwilling to accept the additional costs related to installing and utilizing the
AcCell 2000/2001 and the TracCell 2000.
 
    LIMITED  NUMBER  OF  CUSTOMERS.    Due in  part  to  a  recent  trend toward
consolidation of clinical laboratories, the  Company expects that the number  of
potential  domestic customers for its  cytopathology products will decrease. Due
to the relative  size of the  largest United States  laboratories, it is  likely
that  a significant portion of the sales  of AcCell 2000/2001 and TracCell 2000,
if approved  for  marketing by  the  FDA, sales  will  be concentrated  among  a
relatively  small  number  of customers.  The  Company  will need  to  foster an
awareness of and acceptance by these potential customers of the AcCell 2000/2001
and the TracCell 2000, for patient data management, slide handling, mapping  and
 
                                       12

slide  review documentation and  the benefits of  such systems over conventional
methods. The Company's dependence on sales to large laboratories may  strengthen
the purchasing leverage of these potential customers. There can be no assurances
that  the Company will be  successful in selling its  products, or that any such
sales will  result  in  sufficient  revenue  to  allow  the  Company  to  become
profitable.
 
    TECHNOLOGICAL  CHANGE  AND  COMPETITION.    The  Company's  AcCell 2000/2001
currently faces, and the TracCell 2000 mapping system, if successfully developed
and approved  by the  FDA, will  face  competition from  companies that  may  be
developing  competing systems. The  Company believes that  many of the Company's
existing  and  potential  competitor  companies  possess  substantially  greater
financial,  marketing,  sales,  distribution and  technical  resources  than the
Company, and  more  experience in  research  and development,  clinical  trials,
regulatory  matters, manufacturing  and marketing. The  Company is  aware of two
companies which  currently  market imaging  systems  to re-examine  or  rescreen
conventional  Pap smears previously diagnosed as negative as was another company
that is developing devices for the production and analysis of Pap smear  slides.
If  either company marketing rescreening products  receives FDA approval for one
as a primary screening system to replace conventional Pap smears or if automated
analysis systems are developed and receive FDA approval, the Company's  business
financial  condition and results of operations could be materially and adversely
affected.
 
    The market for  the Company's microbiology  products is highly  competitive,
and  the Company  competes with  numerous well-established  foreign and domestic
companies, most  of which  possess substantially  greater financial,  technical,
marketing,  personnel and other resources than  the Company and have established
reputations for success in the development,  sale and service of manual and/  or
automated  in vitro  diagnostic testing products.  A significant  portion of the
MIC/ID testing  market in  the United  States is  controlled by  two  companies,
Microscan  and  bioMerieux  Vitek.  These  companies  market  a  broad  range of
medically related products  and have  resources far  greater than  those of  the
Company.  Difco Laboratories,  Inc. ("Difco")  has been  issued a  United States
patent covering technology similar  to the Alamar technology  covered in one  of
the  Company's patents. The  Company's patent is  intended to provide protection
for the relevant  Alamar technology when  used in conjunction  with a  "poising"
agent used to stabilize the bacterial susceptibility process. The Company is not
aware  of  Difco's  plans,  if any,  to  exploit  the patent.  There  can  be no
assurances that Difco, which has substantially greater resources and  experience
in research, development, manufacturing and marketing than the Company, will not
use  its patented technology to develop products that will compete directly with
the Alamar microbiology products. In addition,  the Company is aware of  several
potential  competitors with similar  competitive advantages in  markets that the
Company intends to enter in  the future. There can  be no assurances that  other
technologies  or  products,  which  are functionally  similar  to  those  of the
Company, are  not  currently  available  or under  development,  or  that  other
companies  with expertise and resources that  would encourage them to attempt to
develop and market competitive products  will not develop new products  directly
competitive with the Company's products.
 
    The  cytopathology and  medical diagnostic  industries are  characterized by
rapid product  development and  technological advances.  The Company's  products
could  be  rendered  obsolete or  uneconomical  by the  introduction  and market
acceptance of  competing  products,  technological  advances  of  the  Company's
current  or  potential competitors,  or  by other  approaches.  There can  be no
assurances that the Company will be able to compete successfully against current
or future  competitors  or  that  competition,  including  the  development  and
commercialization  of  new products  and technology,  will  not have  a material
adverse effect  on the  Company's business,  financial condition  or results  or
operations.
 
    RISK OF LITIGATION; PRODUCT LIABILITY INSURANCE; POTENTIAL UNAVAILABILITY OF
INSURANCE.   The  commercial screening of  Pap smears has  been characterized by
significant malpractice  litigation. The  Company faces  a risk  of exposure  to
product  liability, errors and omissions  or other claims in  the event that the
use of its  AcCell 2000/2001 or  other future potential  products including  the
TracCell 2000, if approved
 
                                       13

   
for  marketing  by the  FDA, is  alleged to  have resulted  in a  false negative
diagnosis. While  the AcCell  2000/2001 is  a slide  handling and  patient  data
management  instrument and  the TracCell  2000 is  being designed  to facilitate
slide mapping and human review that do not purport to diagnose any slide,  there
can  be no  assurances that  the Company  will avoid  significant liability. The
Company currently  maintains  a  product liability  insurance  policy  providing
maximum  coverage of $10,000,000 and per occurrence coverage of $10,000,000. The
medical device  industry in  general has  experienced increasing  difficulty  in
obtaining and maintaining reasonable product liability coverage, and substantial
increases  in  insurance  premium costs  in  many cases  have  rendered coverage
economically impractical. There can be no assurances that the Company's existing
product liability insurance  will be adequate  or continue to  be available,  or
that  additional product  liability insurance will  be available  to the Company
when needed  or at  a reasonable  cost. An  inability to  maintain insurance  at
acceptable  costs or otherwise protect against potential product liability could
prevent or inhibit the continued commercialization of the Company's products. In
addition, a product liability claim in excess of relevant insurance coverage  or
product  recall could have a material  adverse effect on the Company's business,
financial condition  and  results of  operations.  The Company  also  faces  the
possibility  that defects in designs or manufacture of its products could result
in product recall.
    
 
    POTENTIAL FLUCTUATIONS IN  FUTURE QUARTERLY  RESULTS.   The Company  expects
that  its operating results will fluctuate significantly from quarter to quarter
in the future and will  depend on the timing and  level of market acceptance  of
the  Company's  products,  the  level of  expenditures  associated  with product
development activities, the results  of factors, many of  which are outside  the
Company's  control.  These  factors  include  the  timing  of  these activities,
including the TracCell  2000 and  TracCell 3000,  the effectiveness  of the  OEM
distributor   in  the  sale  of  the  AcCell  2000/2001  and,  possibly,  future
cytopathology products,  the  likelihood  and  timing  and  costs  in  obtaining
necessary regulatory approval of the timing and level of expenditures associated
with  expansion of  sales and marketing  activities and  overall operations, the
Company's ability to cost effectively expand manufacturing capacity and maintain
consistently  acceptable  yields,  the  timing  of  establishment  of  strategic
distribution arrangements and the success of the activities conducted under such
arrangements,   changes  in  demand  for   its  products,  order  cancellations,
competition, changes in government regulation  and other factors, the timing  of
significant  orders  from  and  shipments  to  customers,  and  general economic
conditions. These factors  are difficult  to forecast,  and these  and or  other
factors  could  have  a  material  adverse  effect  on  the  Company's business,
financial condition and results of operations. Fluctuations in quarterly  demand
for  products may adversely affect the continuity of the Company's manufacturing
operations, increase uncertainty in operational planning, disrupt cash flow from
operations and contribute to  the volatility of the  Company's stock price.  The
Company's  expenses are based in part on the Company's expectations as to future
revenue levels and to a large extent are fixed in the short term. If revenues do
not meet expectations, the Company's  business, financial condition and  results
of  operations could be materially adversely affected. The Company believes that
period to  period  comparisons of  its  operating results  are  not  necessarily
meaningful  and should not be relied  upon as indications of future performance.
As a result of the foregoing factors,  it is likely that in some future  quarter
the  Company's revenue  or operating results  will be below  the expectations of
public market analysts and investors. In  such event the price of the  Company's
Common   Stock  could  be  materially  adversely  affected.  Company's  products
requiring such approval.
 
    ENVIRONMENTAL REGULATION.   The Company is  subject to a  variety of  local,
state  and federal and  foreign government regulations  relating to the storage,
discharge, handling, emission,  generation, manufacture and  disposal of  toxic,
infectious  or  other hazardous  substances  used to  manufacture  the Company's
products. The failure to comply with current or future regulations could  result
in  the  imposition  of substantial  fines  against the  Company,  suspension of
production,  alteration  of   its  manufacturing  processes   or  cessation   of
operations.  There can be no assurances that the Company will not be required to
incur significant costs  to comply  with any such  laws and  regulations in  the
future, or that such laws or regulations will not have a material adverse effect
on  the Company's business,  financial condition and  results of operations. Any
failure by the Company to control the  use, disposal, removal or storage of,  or
to  adequately  restrict  the  discharge  of,  or  assist  in  the  cleanup  of,
 
                                       14

hazardous chemicals or hazardous, infectious  or toxic substances could  subject
the  Company to significant  liabilities, including joint  and several liability
under certain statutes. The imposition of such liabilities would have a material
adverse effect on  the Company's  business, financial condition  and results  of
operations.
 
    UNCERTAINTY  OF PROFITABLE MANUFACTURING.   At the end  of 1995, the Company
acquired Sensititre's manufacturing  facility near  London, England.  Sensititre
has  been manufacturing Sensititre products for many years in the U.K. and since
July 1995, has  been manufacturing Alamar  products at such  facility. Prior  to
July  1995, however, the  Company manufactured Alamar products  at a facility in
Sacramento, California. The Company was unable to reduce manufacturing costs  at
the  Sacramento  facility to  a  level that  would  have allowed  for profitable
operations. While it is expected that  consolidation of the Alamar product  line
manufacturing  effort in  the U.K. facility  may result in  certain economies of
scale, there can be  no assurances that the  Company's Alamar product line  will
ever be manufactured in a cost-effective manner.
 
    The  Company's Cytopathology Division has  only recently begun assembling of
the AcCell 2000  and AcCell  2001 at  its Chicago  location. In  June 1996,  the
Company  entered into its first OEM Agreement, for the exclusive distribution of
certain cytopathology  products  in the  Western  Hemisphere. There  can  be  no
assurances  that the Company will be able  to sell sufficient numbers of systems
or   develop   volume   manufacturing   processes,   that   will   lead   to   a
profitable/cost-effective manufacture of the AcCell products.
 
    The  Company's  semi-automated and  fully-automated instruments  for reading
results of  microbiology diagnostic  test kits,  READar, PIPETar  and ARIS,  are
manufactured  for the  Company by  the developers of  such products  or by other
outside vendors. There  can be  no assurances that  any of  these developers  or
vendors  will  be able  to  manufacture the  Alamar  product line's  current and
proposed automated reading or related products in a cost-effective manner.
 
    DEPENDENCE ON SUPPLIERS.  Certain key  components and raw materials used  in
the   manufacturing  of  the  Company's   products  are  currently  provided  by
single-source vendors. Although  the Company believes  that alternative  sources
for such materials and raw materials are available, any supply interruption in a
single-sourced component or raw material would have a material adverse effect on
the  Company's ability to manufacture products until a new source of supply were
qualified. There can  be no assurance  that the Company  would be successful  in
qualifying  additional sources on a  timely basis or at  all, which would have a
material adverse effect on the  Company's business. In addition, an  uncorrected
impurity  or  supplier's variation  in  a raw  material,  either unknown  to the
Company or incompatible with the  Company's manufacturing process, could have  a
material adverse effect on the Company's ability to manufacture products.
 
    IMPACT  OF MEDICARE, MEDICAID  AND OTHER THIRD-PARTY  REIMBURSEMENT.  In the
United States, many Pap smears and MIC/ID testing are currently paid for by  the
patient,  and the level  of reimbursement by third-party  payers that do provide
reimbursement  varies  considerably.  Third-party  payers  (Medicare/  Medicaid,
private health insurance, health administration authorities in foreign countries
and   other  organizations)   may  affect   the  demand,   pricing  or  relative
attractiveness  of  the  Company's  products  and  services  by  regulating  the
frequency  and maximum  amount of  reimbursement for  Pap screenings  and MIC/ID
testing provided by such  payers or by not  providing any reimbursement at  all.
Restrictions  on reimbursement for  Pap screenings and  MIC/ID testing may limit
the price which the Company can charge for its products or reduce the demand for
them. In addition, if Medicare and Medicaid do not provide for reimbursement for
Pap screenings and  MIC/ID testing,  or if the  level of  such reimbursement  is
significantly  below the  amount laboratories  and hospitals  charge patients to
perform Pap  screenings  and  MIC/ID  testing, respectively,  the  size  of  the
potential  market  available to  the Company  may  be reduced.  There can  be no
assurances that the level  of reimbursement to  laboratories for Pap  screenings
and  MIC/ID testing will achieve or be  maintained at levels necessary to permit
the Company to generate substantial revenues or be profitable.
 
                                       15

    In the international  market, reimbursement by  private third-party  medical
insurance  providers, including governmental insurers and providers, varies from
country to  country. In  certain  countries, the  Company's ability  to  achieve
significant  market penetration may depend  upon the availability of third-party
or governmental reimbursement.
 
    UNCERTAINTY AND POSSIBLE NEGATIVE EFFECTS OF HEALTH CARE REFORM.  The health
care  industry  is  undergoing  fundamental  changes  that  are  the  result  of
political,   economic  and   regulatory  influences.   In  the   United  States,
comprehensive programs have been proposed that seek to control the escalation of
health care expenditures within the economy. Reforms that have been, and may be,
considered include controls on health  care spending through limitations on  the
increase  in  private  health  insurance  premiums  and  Medicare  and  Medicaid
spending, the  creation of  large insurance  purchasing groups  and  fundamental
changes  to  the health  care  delivery system.  Health  care reform  could, for
example, result in  a reduction  in the recommended  frequency of  Pap tests  or
limitations  on reimbursement  based on  the frequency  of Pap  tests and MIC/ID
testing, which would likely  reduce the demand  for the Company's  cytopathology
products  in connection with  Pap smear screening  and microbiology products, as
the case may be.  The Company anticipates that  Congress and state  legislatures
will continue to review and assess cost containment measures, alternative health
care  delivery systems and methods of payment, and public debate of these issues
will likely continue. Due to uncertainties regarding the outcome of health  care
reform  initiatives and their  enactment and implementation,  the Company cannot
predict what reforms will be proposed or adopted or the effect such proposal  or
adoption  may have on the Company. There can be no assurances that future health
care legislation or  other changes  in the administration  or interpretation  of
government  health care  or third-party reimbursement  programs will  not have a
material adverse  effect  on the  Company's  business, financial  condition  and
results of operations.
 
    INTERNATIONAL  SALES AND OPERATIONS  RISKS.  The  Company sells microbiology
products and  intends to  sell  its cytopathology  and  any future  products  to
customers both in the United States and internationally. International sales and
operations may be limited or disrupted by the imposition of government controls,
export  license requirements, political instability, trade restrictions, changes
in tariffs or  difficulties in staffing  and managing international  operations.
Foreign  regulatory agencies  often establish  product standards  different from
those in  the United  States  and any  inability  to obtain  foreign  regulatory
approvals  on  a  timely basis  could  have  a material  adverse  effect  on the
Company's  international  business   operations.  Additionally,  the   Company's
business,  financial  condition  and  results  of  operations  may  be adversely
affected by  increases in  duty  rates and  difficulties in  obtaining  required
licenses  and permits. There can be no  assurances that the Company will be able
to successfully  commercialize its  products,  or any  future products,  in  any
foreign market.
 
    NEED  TO  MANAGE EXPANDING  OPERATIONS.   If  the  Company is  successful in
achieving market acceptance for  its AcCell 2000/2001  systems and the  TracCell
2000  (if regulatory  approvals are obtained),  the Company will  be required to
expand its operations,  particularly in  the areas  of sales  and marketing  and
manufacturing.  As  the  Company expands  its  operations in  these  areas, such
expansion  will  likely  result  in  new  and  increased  responsibilities   for
management personnel and place significant strain upon the Company's management,
operating  and financial systems  and resources. To  accommodate any such growth
and compete effectively, the Company will  be required to implement and  improve
information systems, procedures and controls, and to expand, train, motivate and
manage its work force. The Company's future success will depend to a significant
extent  on the ability of its current and future management personnel to operate
effectively, both independently and as a  group. There can be no assurance  that
the  Company's personnel, systems,  procedures and controls  will be adequate to
support the Company's future  operations. Any failure  to implement and  improve
the Company's operational, financial and management systems or to expand, train,
motivate  or manage employees as required by future growth, if any, could have a
material adverse  effect  on the  Company's  business, financial  condition  and
results of operations.
 
    DEPENDENCE  ON KEY  EMPLOYEES.  The  Company believes that  its success will
depend to a significant extent, upon the efforts and abilities of a small  group
of executive, scientific and marketing personnel,
 
                                       16

in  particular,  Peter  P.  Gombrich,  the  Company's  Chief  Executive Officer,
President and Chairman of the Board. The loss of the services of one or more  of
these  key  personnel could  have  a material  adverse  effect on  the Company's
business, financial  condition  and  results of  operations.  In  addition,  the
Company's future success will depend upon its ability to continue to attract and
retain  qualified scientific and  management personnel who  are in great demand.
There can be no assurances that the Company will be successful in attracting and
retaining such personnel.
 
    POSSIBLE VOLATILITY OF STOCK PRICE.  The  market price of the shares of  the
Company's  Common Stock,  like that  of the common  stock of  many other medical
products and high technology companies, has in  the past been, and is likely  in
the  future to continue to  be highly volatile. Factors  such as fluctuations in
the Company's operating results,  announcements of technological innovations  or
new  commercial products by  the Company or  competitors, government regulation,
changes in  the current  structure  of the  health  care financing  and  payment
systems,  developments  in or  disputes  regarding patent  or  other proprietary
rights, economic and other  external factors and  general market conditions  may
have a significant effect on the market price of the Common Stock. Moreover, the
stock  market  has  from  time  to time  experienced  extreme  price  and volume
fluctuations which  have particularly  affected the  market prices  for  medical
products  and high technology  companies and which have  often been unrelated to
the operating performance of such companies. These broad market fluctuations, as
well as general economic, political and market conditions, may adversely  affect
the  market price of the Company's Common  Stock. In the past, following periods
of volatility in the market price of a company's common stock, securities  class
action  litigations have occurred  against the issuing company.  There can be no
assurance that such litigation will not occur in the future with respect to  the
Company.  Such litigation could  result in substantial costs  and a diversion of
management's attention and resources, which could have a material adverse effect
on the  Company's  business,  operating results  and  financial  condition.  Any
adverse  determination  in such  litigation could  also  subject the  Company to
significant liabilities.
 
    LACK OF DIVIDENDS.  The  Company has never paid  cash or other dividends  on
its  Common Stock  and does  not intend to  pay cash  or other  dividends in the
foreseeable future. See "Dividend Policy."
 
    AUTHORIZATION AND  POTENTIAL ISSUANCE  OF PREFERRED  STOCK.   The  Company's
Certificate  of Incorporation  authorizes the  issuance of  preferred stock with
such designation, rights and preferences as may be determined from time to  time
by  the Board  of Directors. Accordingly,  the Board of  Directors is empowered,
without  stockholder  approval,   to  issue  preferred   stock  with   dividend,
liquidation, conversion, voting or other rights which could adversely affect the
voting  power or  other rights  of the  holders of  the Company's  Common Stock.
Although the  Company does  not currently  intend  to issue  any shares  of  its
preferred  stock, in the event of issuance, such shares could be utilized, under
certain circumstances, as  a method  of discouraging, delaying  or preventing  a
change  in control of the  Company. There can be  no assurances that the Company
will not, under certain circumstances, issue shares of its preferred stock.
 
   
    OUTSTANDING WARRANTS AND  OPTIONS.  Investors  purchasing Shares will  incur
dilution  to the extent outstanding stock options and warrants are exercised. As
of the date of  this Prospectus, there  are outstanding immediately  exercisable
(i)  warrants to  purchase 5,969,333 shares  of Common Stock  at exercise prices
ranging from $0.25 to $5.00 per share with a weighted average exercise price  of
$3.21, and (ii) options to purchase 1,652,971 shares of Common Stock at exercise
prices ranging from $0.63 to $8.38 per share.
    
 
   
    SHARES  ELIGIBLE FOR FUTURE  SALE; REGISTRATION RIGHTS.   As of  the date of
this Prospectus,  there  are  18,631,453 shares  of  Common  Stock  outstanding.
Approximately 13,000,000 shares of Common Stock or shares issuable upon exercise
of  currently exercisable  warrants and  options sold  or registered  for resale
pursuant to registration statements,  or for which  there exist exemptions  from
the  registration requirements  under the  Securities Act,  are freely tradeable
without restriction or requirement of  further registration, unless such  shares
are  held  by  "affiliates" of  the  Company (as  that  term is  defined  in the
Securities Act  and  the regulations  promulgated  thereunder) and  subject,  in
certain
    
 
                                       17

   
instances, to the prospectus delivery requirements under the Securities Act. The
balance  of the shares were  sold by the Company  in reliance on exemptions from
the registration requirements of  the Securities Act.  In addition, the  Company
has  granted certain demand, and/or piggyback registration rights, relating to a
substantial portion of the restricted shares and a substantial number of  shares
of  Common Stock underlying warrants issued  by the Company. Any future exercise
of such  registration  rights, and  sale  of  such securities,  will  result  in
dilution in the interest of the Company's then existing stockholders.
    
 
    No  prediction can be  made as to the  effect, if any,  that future sales of
additional shares of Common Stock or  the availability of such shares for  sale,
whether  pursuant to  exercised registration rights  or under Rule  144 or other
applicable exemptions under the Securities Act, will have on the market price of
the Common Stock  prevailing from  time to time.  Nevertheless, the  possibility
that  substantial amounts of Common  Stock may be sold  in the public market may
adversely affect prevailing market prices for the Common Stock and could  impair
the  ability of  the Company  to raise  capital through  the sale  of its equity
securities.

                                DIVIDEND POLICY
 
    The Company has not paid any cash or other dividends on its Common Stock  to
date.  The Company currently intends to retain  future earnings, if any, for its
business and does not anticipate paying  any cash dividends on its Common  Stock
in the foreseeable future.
 
                          PRICE RANGE OF COMMON STOCK
 
    The  Company's Common  Stock is  traded in  the over-the-counter  market and
quoted on Nasdaq under the symbol "ACMI."  The table below sets forth the  range
of  high and low  closing prices for the  Common Stock as  reported on Nasdaq in

- ------------------------
(1) On December 31,  1995, the Company  changed its fiscal  year from October  1
    through  September  30  to January  1  through December  31.  Therefore, the
    "Transition Period" includes October 1, 1995 through December 31, 1995.
 
   
    On July 1, 1996 the closing price of the Common Stock as reported by  Nasdaq
was  $6.25  per  share. At  July  1,  1996, the  Company  had  approximately 260

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
   
    The  following unaudited  pro forma condensed  combined financial statements
give effect of  the Merger of  Alamar and  AccuMed and the  purchase of  certain
assets  and  the  assumption  of  certain  liabilities  from  Sensititre  US and
Sensititre UK by AccuMed on a purchase basis.
    
 
   
    The unaudited pro forma condensed combined statements of operations for  the
year  ended September  30, 1995  and the  three months  ended December  31, 1995
assume that  the Merger  with AccuMed  and  the purchase  of Sensititre  US  and
Sensititre UK occurred on October 1, 1994.
    
 
   
    The  pro  forma  adjustments are  based  on preliminary  assumptions  of the
allocation of the purchase  price and are subject  to substantial revision  once
evaluation  of  the fair  value of  the  assets and  liabilities of  AccuMed are
completed. Actual purchase accounting adjustments may differ from the pro  forma
adjustments presented herein.
    
 
   
    THE  UNAUDITED  PRO FORMA  CONDENSED COMBINED  FINANCIAL STATEMENTS  ARE NOT
NECESSARILY INDICATIVE OF THE RESULTS THAT  ACTUALLY WOULD HAVE OCCURRED IF  THE
MERGERS  HAD  BEEN  COMPLETED  ON  THE  ASSUMED  DATES  NOR  ARE  THE STATEMENTS
INDICATIVE OF FUTURE COMBINED FINANCIAL POSITION OR EARNING.
    
 
   
    The pro forma condensed financial  statements should be read in  conjunction
with  the financial statements of Alamar for the fiscal year ended September 30,
1995 and the financial statements for  the transition period ended December  31,
1995.

(1) Unless otherwise noted, the Company  believes that all persons named in  the
    table  have sole voting and  investment power with respect  to all shares of
    Common Stock listed as beneficially owned by them. A person is deemed to  be
    the  beneficial holder  of securities  that can  be acquired  by such person
    within 60 days  from the  Reference Date upon  the exercise  of warrants  or
    options.  Each  beneficial  owner's percentage  ownership  is  determined by
    including shares underlying  options or  warrants which  are exercisable  by
    such  person currently or  within 60 days following  the Reference Date, and
    excluding shares underlying options and warrants held by any other person.
    
 
    The Company has agreed to indemnify certain of the Selling Stockholders  and
the  Selling Stockholders have  agreed to indemnify  the Company against certain
civil liabilities, including liabilities under the Securities Act.
 
    Except as noted in the footnotes above, none of the Selling Stockholders has
held any office or maintained any material relationship with the Company  during
the past three years.

                              PLAN OF DISTRIBUTION
 
    The  Common Stock  and Warrants  offered hereby may  be sold  by the Selling
Stockholders  from   time  to   time  as   market  conditions   permit  in   the
over-the-counter market, or otherwise, at prices and terms then prevailing or at
prices  related to the then current market price, or in negotiated transactions.
The shares offered hereby may be sold  by one or more of the following  methods,
without  limitation: (a) a  block trade in  which a broker  or dealer so engaged
will attempt to sell the shares as  agent but may position and resell a  portion
of  the block  as principal  to facilitate the  transaction; (b)  purchases by a
broker or  dealer as  principal and  resale by  such broker  or dealer  for  its
account  pursuant to  this Prospectus;  (c) ordinary  brokerage transactions and
transactions in  which  the broker  solicits  purchasers; and  (d)  face-to-face
transactions   between  sellers  and  purchasers  without  a  broker-dealer.  In
effecting sales,  brokers or  dealers engaged  by the  Selling Stockholders  may
arrange for other brokers or dealers to participate. Such brokers or dealers may
receive  commissions or  discounts from  Selling Stockholders  in amounts  to be
negotiated immediately prior to the sale. Such brokers or dealers and any  other
participating  brokers or dealers may be  deemed to be "underwriters" within the
meaning of the Securities  Act in connection with  such sales. In addition,  any
securities covered by this Prospectus that qualify for sale pursuant to Rule 144
under  the Securities Act might  be sold under Rule  144 rather than pursuant to
this Prospectus.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The  Company  has  provisions  in  its  Certificate  of  Incorporation which
eliminate the  liability of  the  Company's directors  to  the Company  and  its
stockholders  for  monetary  damages  to the  fullest  extent  permissible under
Delaware law  and  provisions  which  authorize the  Company  to  indemnify  its
directors  and agents by bylaws, agreements  or otherwise, to the fullest extent
permitted by law. Such limitation of liability does not affect the  availability
of  equitable remedies  such as injunctive  relief or  rescission. The Company's
Bylaws provide that the  Company shall indemnify its  directors and officers  to
the fullest extent permitted by Delaware law.
 
    The  Company's  officers  and  directors are  covered  by  a  director's and
officer's liability  insurance  policy  maintained by  the  Company.  Under  the
insurance  policy,  the  Company  is entitled  to  be  reimbursed  for indemnity
payments that it is required or permitted to make to its directors and officers.

ITEM 17.  UNDERTAKINGS
 
    The undersigned registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being  made,
    a  post-effective amendment  to this  registration statement  to include any
    additional or  changed material  information  with respect  to the  plan  of
    distribution.
 
        (2)  That,  for  the  purpose of  determining  any  liability  under the
    Securities Act of 1933, each  such post-effective amendment shall be  deemed
    to  be  a  new registration  statement  relating to  the  securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) To remove from registration  by means of a post-effective  amendment
    any   of  the  securities  being  registered  which  remain  unsold  at  the
    termination of the offering.
 
    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 (the  "Act") may  be permitted  to directors,  officers and controlling
persons of the Company pursuant to  the foregoing provisions, or otherwise,  the
Company  has been  advised that  in the opinion  of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for  indemnification
against  such liabilities  (other than  the payment  by the  Company of expenses
incurred or paid by a director, officer or controlling person of the Company  in
the  successful defense of any  action, suit or proceeding)  is asserted by such
director, officer or controlling person in connection with the securities  being
registered,  the Company will, unless  in the opinion of  its counsel the matter
has been settled  by controlling  precedent, submit  to a  court of  appropriate
jurisdiction  the question whether such indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                                   SIGNATURES

has duly caused  this Registration Statement  on Form  S-3 to be  signed on  its
behalf  by the undersigned,  thereunto duly authorized, in  the City of Chicago,
State of Illinois on             , 1996.
