ITEM 1.  BUSINESS
GENERAL
 
    Cholestech   Corporation   ("Cholestech"   or   the   "Company")   develops,
manufactures and  markets a  proprietary point  of care  diagnostic system  (the
"L-D-X  System") which measures specific analytes to detect various diseases and
disorders within five minutes  using a single drop  of whole blood. The  Company
currently  markets its L-D-X System and a series of lipid and glucose panels for
preventive screening and  monitoring applications.  In January  1996, the  L-D-X
System  and the  Company's total  cholesterol ("TC"),  high density lipoproteins
("HDL"), triglycerides and glucose  tests were granted  waived status under  the
Clinical  Laboratory  Improvement Amendments  of 1988  ("CLIA"), the  first such
waiver granted under CLIA's newly-developed ease of use, accuracy and  precision
guidelines. The CLIA waiver allows health care providers to use the L-D-X System
without  the additional  operating costs  and extensive  regulatory requirements
associated with CLIA compliance. The Company  believes that the L-D-X System  is
the  only multi-analyte diagnostic system to be classified as waived under CLIA.
The Company believes that the  L-D-X System's CLIA waived status,  technological
flexibility,  ease of  use, accuracy and  low maintenance costs  provide it with
competitive advantages over other point of care diagnostic systems.
 
MARKET OVERVIEW
 
    Diagnostic testing of blood for chronic diseases and disorders is  typically
performed  in independent  clinical laboratories  or hospital-based laboratories
where large numbers of blood samples  are processed in batches and test  results
are often not returned to physicians in less than 24 hours. The Company believes
that  as a  result of  the potential  benefits and  advantages of  point of care
testing, there  exists  an opportunity  to  shift certain  types  of  diagnositc
testing  from clinical laboratories and hospital-based laboratories to the point
of care. These potential benefits  and advantages include permitting the  health
care  practitioner  to provide  immediate  feedback to  the  patient as  well as
allowing  health  care   practitioners  to  closely   monitor  the   therapeutic
effectiveness  of treatment and thereby  improve patient compliance. The Company
also believes that point of care  testing could help to reduce overall  delivery
costs  and could  improve patient  outcomes by  providing diagnosis  as close to
 
                                       2
<PAGE>
the patient as  possible, thereby  eliminating the need  for additional  patient
follow-up  with test  results and  redundant and  time consuming  procedures and
processes, reducing paperwork and minimizing the time to medical intervention.
 
    Two of the principal markets in which point of care testing is performed are
the  screening  and  monitoring  markets.  The  screening  market  is  generally
comprised  of hospitals,  corporate wellness programs,  health promotion service
providers, managed care organizations,  community health centers, public  health
programs,  fitness centers, the military  and other independent screeners. These
health care  providers focus  on identifying  patients who  may be  at risk  for
certain  diseases or disorders and directing  them to appropriate therapeutic or
preventive care  programs.  The  monitoring market  is  generally  comprised  of
physician  office laboratories  ("POLs"), lipid  clinics, cardiac rehabilitation
centers and pharmacies. These health care providers focus on disease  management
and  perform testing to monitor  (i) patients who are  identified as at risk for
certain diseases, (ii) patients on dietary  or drug therapy, and (iii)  patients
at  risk  of,  or  who  have  suffered, heart  attacks  or  who  are  in cardiac
rehabilitation. The Company believes that the number of potential point of  care
testing  sites is large. For example, the National Cholesterol Education Program
("NCEP") and American Heart Association  have encouraged cholesterol testing  in
such  places as worksites, community health  centers and a variety of preventive
medicine programs  in  order  to  make such  testing  readily  available.  Until
recently,  point of  care testing has  been conducted predominately  in the high
volume  screening  and  monitoring  settings.  Point  of  care  testing  in  the
monitoring  market has been embraced by low  volume POLs only on a limited basis
due  to  the  costs  and  administrative  burdens  associated  with   government
regulatory  requirements. In addition, technological limitations have restricted
the number of  tests which can  be performed  cost effectively at  the point  of
care.
 
    Historically, the Federal Clinical Laboratory Improvement Amendments of 1967
applied  only to clinical  and hospital-based laboratories,  and physicians were
able to perform any  laboratory testing that they  believed was appropriate  for
their  patients. The POL market  grew as a result of  the development of easy to
use laboratory testing equipment and  the economic incentives for physicians  to
perform  such testing in their own  offices. In 1988, the regulatory environment
in the POL market  changed with the  promulgation of CLIA  which applies to  all
laboratories,  including POLs, which  perform testing on  human specimens. Under
CLIA, all laboratories are required to  register with the Health Care  Financing
Administration  ("HCFA"), but laboratories conducting  non-waived tests must pay
higher  registration   fees  and   submit  to   biannual  federal   inspections.
Laboratories  conducting  non-waived  tests  are also  required  to  implement a
comprehensive quality  assurance program,  which includes  a detailed  procedure
manual, enrollment in a proficiency testing program and a requirement to run two
levels of quality control material each day of testing, even if only one patient
sample  is run. Moreover,  CLIA regulations include  personnel requirements that
vary depending  on  the  complexity  of  tests  performed.  See  "--  Government
Regulation."   Since  POL  testing  is  often  done  in  low  volumes  and  CLIA
requirements  can  significantly  increase  the  costs  of  testing,  performing
non-waived tests in a POL setting, particularly in low volume POLs, is often not
cost  effective. When CLIA regulations went into effect in 1992, many physicians
discontinued all but waived  testing. Clinical and hospital-based  laboratories,
however,  have  continued to  perform  such testing  and  as a  result currently
dominate this market.
 
  SCREENING MARKET
 
    In  the  screening  market,  health  care  providers  perform  high   volume
preventive  risk  factor screening,  particularly  for cholesterol  and glucose.
Although not subject to reimbursement by  Medicare or other third party  payors,
risk  factor screening has proven to be an effective way to decrease the overall
cost of medical care. Hospitals and health departments offer health screening in
local communities. Many  corporations offer periodic  cholesterol screenings  to
their  employees at the worksite as  part of worksite health promotion programs.
Of those  companies providing  cholesterol  screenings, approximately  30%  also
measure  glucose. Worksite health promotion  is advocated by government agencies
such as the National Heart, Lung and Blood Institute and the Centers for Disease
Control
 
                                       3
<PAGE>
and Prevention  ("CDC"). In  addition,  private organizations  promote  worksite
health  promotion  with  a  variety  of  programs  such  as  the  American Heart
Association's  "Heart  at  Work"  Program  and  the  YMCA's  "Corporate   Health
Enhancement  Program," which  serves more  than 2,000  worksites nationally. The
Public Health  Service  has set  goals  for  the number  of  worksites  offering
cholesterol education and testing to be increased from 16% in 1983 to 50% by the
year  2000. Due to the high volume of testing performed by health care providers
in the screening market, the adoption  of CLIA and its resulting cost  increases
and administrative burdens did not have a significant negative impact on testing
in  the screening market. Since  CLIA went into effect  in 1992, the Company has
focused its sales and marketing efforts on the distribution of its products into
the various segments of the screening market.
 
  MONITORING MARKET
 
    Since the Company  received notice  from the CDC  in January  1996 that  the
L-D-X System and the TC, HDL, triglycerides and glucose tests in any combination
have  been classified as waived  under CLIA, the Company  has expanded its sales
and marketing focus to include the monitoring market, in particular the POL  and
pharmacy segments. There are currently 54,000 POLs which perform different types
of  diagnostic tests. The Company currently offers four of the eight most common
blood chemistry  tests  performed  at  POLs, with  two  additional  tests  under
development.  In  addition, there  are currently  68,000 pharmacies  which could
potentially offer point  of care testing.  The Company believes  that long  term
success in the pharmacy market will be dependent upon the development of patient
monitoring  programs developed by  pharmacies and implemented  with managed care
practitioners and physicians on a local basis.
 
STRATEGY
 
    The Company's business strategy includes the following elements:
 
    - LEVERAGE CORE  TECHNOLOGIES  TO  ENHANCE PRODUCT  OFFERINGS.  The  Company
      intends  to leverage the technological flexibility  of the L-D-X System by
      developing new test cassettes which utilize the existing L-D-X Analyzer in
      order to capitalize  on the  Company's installed based  of instruments  as
      well  as to make  the L-D-X System  more attractive to  new customers. The
      Company is  currently in  various stages  of development  of new  products
      which  utilize  biological markers  for  screening and  monitoring certain
      common diseases, such as metabolic  bone diseases and disorders,  prostate
      cancer  and diabetes. In addition, the Company is developing new tests for
      blood urea nitrogen, uric acid and creatinine for renal function  analysis
      and  liver enzymes for hepatic damage. There  can be no assurance that the
      Company  will   be  able   to  successfully   complete  the   development,
      introduction and scale up of manufacturing of any of these future products
      or  that  any  such  tests  will achieve  a  significant  level  of market
      acceptance. See  "--  Products  -- Products  Under  Development"  and  "--
      Manufacturing."
 
    - INCREASE  PENETRATION  OF  SCREENING  MARKET  AND  EXPAND  INTO MONITORING
      MARKET. The Company believes that the  CLIA waived status of its  products
      will  increase the number of potential  customers in the screening market,
      and will enable the Company to  access the monitoring market. The  Company
      is  currently  developing  new  products to  make  its  product  line more
      attractive to the  POL market as  well as to  expand its screening  market
      offerings.
 
    - EXPAND  DISTRIBUTION CHANNELS. The  Company intends to  augment its direct
      sales and marketing efforts by continuing to establish relationships  with
      selected  third party distributors to strategically access target markets.
      The Company  has  recently  entered into  a  distribution  agreement  with
      Physician  Sales and  Services, Inc. ("PSS"),  one of  the largest medical
      products distributors in the  United States, to sell  the L-D-X System  to
      the POL market.
 
    - ESTABLISH STRATEGIC RELATIONSHIPS. The Company has established and intends
      to  continue to establish strategic  relationships to develop new products
      and  to  expand  its  customer  base.  The  Company  believes  that   such
      relationships   will  enable  it  to   take  advantage  of  the  financial
 
                                       4
<PAGE>
      resources, technological capabilities and market presence of its  partners
      to  enhance its  competitive position in  the screening  market and expand
      into the  monitoring market.  In  May 1996,  the  Company entered  into  a
      development, marketing and licensing agreement with Metra Biosystems, Inc.
      ("Metra Biosystems") to develop an immunoassay test cassette incorporating
      Metra  Biosystems' bone  resorption technology to  be used  with the L-D-X
      System. The Company  is also  participating in  a pilot  program with  the
      American  Pharmaceutical Association  funded by  Merck &  Co. ("Merck") to
      demonstrate the ability  of pharmacists to  improve patient outcomes  with
      drug therapy and behavior modification.
 
TECHNOLOGY
 
    The  L-D-X  System is  a  self-contained, easy  to  use package  of products
consisting of  a  versatile,  telephone-sized electronic  analyzer,  a  line  of
disposable  test  cassettes,  and  accessories that  enable  a  user  to perform
combinations of blood tests  in five minutes or  less. Although no special  user
training  is needed  and the test  sample does  not need to  be pre-treated, the
Cholestech L-D-X System produces  results that are  comparable to the  precision
and   accuracy  typically  seen   in  larger,  more   expensive  bench  top  and
laboratory-based analyzers. Correlation studies of the L-D-X System and clinical
laboratory analyzers have shown that the L-D-X System meets NCEP guidelines  for
precision  and accuracy. In addition, the ease of use and precision and accuracy
of the  L-D-X System  were factors  necessary for  the L-D-X  System to  receive
waived  status under CLIA. The Company believes that it is the only manufacturer
with a CLIA waived multi-analyte diagnostic system.
 
    The Company believes the  L-D-X System provides  the following benefits  and
advantages:
 
    - FLEXIBILITY  OF L-D-X SYSTEM. The design  of the L-D-X System incorporates
      as much of the system's technology as possible into the test cassettes and
      maintains the L-D-X Analyzer  as a flexible measuring  device that can  be
      adapted  as new  tests and other  product upgrades are  introduced. As new
      tests  are   marketed,  encoding   on  the   cassette's  magnetic   stripe
      communicates  the product  change to the  L-D-X Analyzer  and provides the
      L-D-X Analyzer  the information  needed to  measure and  display the  test
      results. Changes that cannot be captured on the cassette's magnetic stripe
      can  be accomplished by software changes in the L-D-X Analyzer's removable
      read only memory ("ROM") pack. This flexible design is intended to  permit
      the  installed base  of users to  incorporate new tests  and other product
      upgrades to the L-D-X System without having to purchase a new analyzer.
 
    - COST EFFECTIVENESS.  The  Company believes  that  point of  care  specimen
      analysis  made possible by  the L-D-X System may  provide savings to third
      party payors and physicians. Point of care testing allows the health  care
      practitioner   to  provide  immediate  results  to  the  patient,  thereby
      increasing the possibility for  improved patient outcomes and  eliminating
      the  requirement  that  the patient  return  to receive  test  results. In
      addition, the Company believes that the L-D-X System's waived status under
      CLIA,  together  with  prevailing  third  party  reimbursement  rates  and
      recommended  fees, may provide a financial  incentive for many health care
      providers to test patients at the point of care and capture revenue rather
      than forwarding it to the clinical laboratory.
 
    - IMMEDIATE RESULTS. The L-D-X System provides the health care  practitioner
      with  results in approximately five  minutes, allowing for immediate point
      of care risk factor analysis,  diagnosis and monitoring. The immediacy  of
      the  test results  allows the practitioner  to begin  treatment during the
      same visit, perform additional  tests if needed  or select an  alternative
      treatment.  The L-D-X System's  ability to provide  immediate test results
      also improves the usefulness of  screening applications, such as  worksite
      testing programs.
 
    - SIMULTANEOUS  PERFORMANCE  OF MULTIPLE  TESTS.  With the  L-D-X  System, a
      single cassette can perform up to four tests simultaneously, enabling  the
      Company  to develop test cassettes that meet specific market needs. In the
      monitoring market,  the  performance  of  multiple  tests  with  a  single
      cassette may also result in more reimbursement revenue for the physician.
 
                                       5
<PAGE>
    - EASE  OF USE.  The L-D-X System  requires no special  medical or chemistry
      training to operate and obtain test results. In addition, the L-D-X System
      eliminates the need to pre-treat the testing sample.
 
    - FEWER OPPORTUNITIES FOR  ERROR. The  L-D-X System eliminates  many of  the
      steps   traditionally   involved  in   blood  testing,   including  sample
      transportation, preparation  and storage,  and interpretation  of  analyte
      color  reactions,  thereby  reducing  opportunities  for  human  error and
      preserving the integrity of the sample.
 
  L-D-X ANALYZER
 
    The L-D-X Analyzer is a  four-channel, reflectance photometer that  measures
the  amount of  light reflected  from the  reaction surfaces  and incorporates a
microprocessor with  on board  software. The  L-D-X Analyzer  contains an  entry
drawer  for insertion of the  cassette, three buttons for  user activation and a
liquid crystal display to present the test measurements. The L-D-X Analyzer  can
also  transmit results to a printer or laboratory management computer system for
data handling  and record  keeping.  The L-D-X  Analyzer includes  cardiac  risk
assessment  software that allows the health care practitioner to perform cardiac
risk assessment  using TC  and  HDL test  results  and information  about  other
cardiac  risk  factors  the  health  care  practitioner  enters  into  the L-D-X
Analyzer.
 
    To run a  test, the health  care provider  presses the "run"  button on  the
L-D-X  Analyzer to open the  cassette drawer, applies the  sample of whole blood
directly to  the test  cassette's sample  well, inserts  the cassette  onto  the
drawer and presses the run button again. All further steps are done by the L-D-X
Analyzer.  Utilizing the information and  instructions encoded on the cassette's
magnetic stripe,  the  L-D-X Analyzer's  on  board microprocessor  controls  the
reaction conditions, controls the optical measurements of analyte concentrations
on  the cassette's reaction pads, executes the required calculations and, within
approximately five  minutes, displays  the quantitative  results on  the  liquid
crystal display.
 
    The  ROM software  that instructs  and controls  the operation  of the L-D-X
Analyzer's on board microprocessor is contained in a removable ROM pack  mounted
in  an access well on  the bottom of the L-D-X  Analyzer. The Company intends to
upgrade the software in  its ROM pack  as the Company  develops new products.  A
user  can then easily  remove the ROM  pack and replace  it with a  new ROM pack
containing upgraded  software.  To  date,  the Company  has  made  available  to
existing  users  a new  ROM pack,  without charge,  containing the  cardiac risk
assessment software described  above, as  well as  a new  ROM pack,  for a  fee,
reflecting certain changes required to receive the CLIA waiver.
 
  DISPOSABLE TEST CASSETTES
 
    The focal point of the L-D-X System is the line of disposable test cassettes
which  incorporate  patented  technology, including  a  method  for distributing
precisely measured plasma  to multiple  reaction pads  for simultaneous  testing
along  with the  technology to  instruct the L-D-X  Analyzer how  to perform the
tests and all related calculations.
 
    Each cassette consists of three parts: a main body that contains the  sample
well  into which the blood  sample is dispensed, a  reaction bar where plasma is
transferred for analysis, and a  magnetic stripe encoded with test  instructions
and  lot specific  calibration information  for the  various chemistries  on the
reaction pads. Capillary action draws a drop of whole blood through a separation
medium within a cassette,  stopping the cellular components  of the blood  while
transferring  a small volume of plasma to the cassette's reaction pads. When the
plasma contacts the reaction pads, the dry chemistry on the reaction pads reacts
with the  analyte(s) in  the  plasma producing  color.  The intensity  of  color
developed  is proportional to the concentration of the analyte(s) in the plasma.
The magnetic stripe contains information needed by the L-D-X Analyzer to convert
the reflected  color  reading  into  a  concentration  level  for  the  accurate
measurement of analytes being tested. This feature frees the user from having to
interpret  any color reaction, relate a reading to a separate chart or input any
calibration information.
 
                                       6
<PAGE>
    For certain future tests, the Company will be required to modify the  design
of  the existing dry chemistry cassette.  For example, the Company's immunoassay
tests currently under  development require the  use of antibodies  bound to  the
reaction  membrane  and a  wash step  which removes  bound reactants  that would
interfere with the test. The new immunoassay cassette under development has  the
same  external dimensions as the currently available dry chemistry cassette, but
will require the  Company to  develop new technologies  that would  allow it  to
perform  an immunoassay test,  of which there  can be no  assurance. The Company
believes that, if the immunoassay cassette is successfully developed, the  L-D-X
Analyzer  will be the  only instrument capable of  performing both dry chemistry
and immunoassay-based tests on a single instrument. See "-- Products -- Products
Under Development."
 
PRODUCTS
 
    The Company's current products  include the L-D-X Analyzer  and a series  of
lipid  and glucose test  cassettes for the screening  and monitoring markets. In
addition, the Company is in  the process of developing  new tests to expand  its
product  menu, including immunoassay-based test  cassettes to provide preventive
monitoring assays for the detection of metabolic bone diseases and disorders and
prostate cancer. The following table  summarizes the Company's current  cassette

  CURRENT PRODUCTS
 
    The  Company's current  products are designed  to measure  and monitor blood
cholesterol and related lipids  and glucose. Lipids travel  in the blood  within
water-soluble  particles called lipoproteins. These  lipid carriers include VLDL
(very-low-density lipoproteins), LDL  (low-density lipoproteins)  and HDL  (high
density  lipoproteins). VLDL, a major carrier of triglycerides in the blood, and
LDL, the major  carrier of cholesterol,  have been shown  to be associated  with
deposits   on  the   arterial  wall,   which  are   sometimes  referred   to  as
atherosclerotic plaque. The accumulation of this plaque leads to a narrowing  of
the arteries and increases the likelihood of coronary heart disease, the leading
cause of death in the United States. HDL particles, which circulate in the blood
and  can  pick  up cholesterol  from  arteries and  carry  it to  the  liver for
elimination from  the  body, counterbalance  this  mechanism. HDL  is  sometimes
called  "good cholesterol" because of this function. The development of coronary
heart disease has been associated with three lipoprotein abnormalities: (i) high
levels of LDL; (ii) high levels of VLDL; and (iii) low levels of HDL.
 
    Recognizing the  relationship between  diabetes and  dyslipidemia  (abnormal
lipid  levels),  Cholestech  developed  a glucose  test  for  the  L-D-X System.
Diabetes is a complex disorder of  carbohydrate, fat and protein metabolism.  It
is  manifested by a relative or absolute deficiency in insulin, the hormone that
facilitates and  controls  the  use of  glucose  by  the body.  Because  of  the
deficiency  of insulin, diabetic patients have an impaired tolerance to glucose,
which leads to a number of short term and long term complications, such as nerve
damage, kidney disease and retinal damage.
 
    The Company's  L-D-X  System  includes the  L-D-X  Analyzer  which  measures
analyte  concentrations  on  the  test cassette  and  displays  the quantitative
results. The L-D-X Analyzer currently has a list price of $1,795. A  description
of the Company's test cassettes is provided below.
 
    TC.    A stand  alone  test for  measuring  total cholesterol.  The  TC test
currently has a list price of $2.95.
 
    TC AND HDL PANEL.  The total cholesterol and HDL cholesterol panel  provides
results  for TC  and HDL  and calculates the  ratio of  TC to  HDL, a recognized
measure of lipid-induced cardiac risk. The Company believes that the TC and  HDL
Panel  is the only  currently available point  of care test  which, using only a
single drop of  whole blood from  a simple fingerstick,  addresses the  National
Institutes  of Health  ("NIH") guidelines  regarding the  evaluation of coronary
heart disease through the  testing of not  only TC, but  also the important  HDL
component.  As  a  result,  the  Company  believes  the  TC  and  HDL  Panel  is
particularly useful in  corporate wellness and  initial screening  applications.
The TC and HDL Panel currently has a list price of $7.50.
 
    LIPID  PROFILE.  The Company offers  a Lipid Profile which directly measures
TC, HDL and triglycerides. In addition  to providing direct results for TC,  HDL
and  triglycerides, the  Lipid Profile calculates  estimated values  for LDL and
VLDL and calculates the  ratio of TC  to HDL. The  Lipid Profile thus  performs,
using  a  small sample  of  whole blood  from  a simple  fingerstick,  each test
identified by  the NIH  guidelines as  important in  the diagnosis  and  ongoing
monitoring  of individuals who  have high TC  levels or who  exhibit two or more
other coronary heart  disease risk factors.  The Lipid Profile  also allows  the
health  care practitioner  to follow the  NIH guidelines to  perform three lipid
profiles, each one week apart, prior to initiating drug or dietary therapy.  The
Lipid Profile currently has a list price of $9.95.
 
    TC   AND  GLUCOSE  PANEL,  TC/HDL/GLUCOSE   PANEL  AND  LIPID  PROFILE  PLUS
GLUCOSE.  These panels  address the need for  screening and monitoring  patients
with  demonstrated or incipient diabetes mellitus  and individuals who may be at
risk of cardiovascular disease  and individuals who may  not be aware that  they
are  diabetic. These test combinations are potentially desirable because glucose
and TC tests are frequently conducted  at occupational health sites. The TC  and
Glucose  Panel, the TC/HDL/Glucose Panel and the Lipid Profile plus Glucose have
a list price of $3.95, $8.50 and $10.95, respectively.
 
                                       8

    MARKETS.   In response  to conclusive  evidence relating  high TC  to  heart
disease,  the NIH in 1985  launched the NCEP, a  nationwide effort to reduce the
prevalence of high blood  cholesterol. In 1988, the  NCEP issued guidelines  for
the  testing of all adults over 20 years  of age for high blood cholesterol, and
more extensive lipid monitoring and treatment for those found to be in high risk
categories. Testing guidelines  were subsequently expanded  to include  children
over  the age of two with a family history of high blood cholesterol or coronary
heart  disease  and  to  include  in  certain  circumstances  a  lipid  profile,
consisting  of  TC, HDL,  LDL and  triglycerides. Since  the NCEP  initiated its
recommendations,  the  market  for  cholesterol   and  other  lipid  tests   has
experienced  significant growth.  NCEP data indicate  that more than  50% of the
adult population in the United States has high or borderline high TC.
 
    It is estimated that Type II diabetes, which involves insulin deficiency  or
insulin  resistance, afflicts more than 14 million persons in the United States,
but only half of those with Type II diabetes have been identified. Screening for
these patients who  have non-symptomatic diabetes  is important, because  proper
treatment will minimize the long term complications of the disease.
 
    In  order for the Company to increase revenues and achieve profitability and
positive cash flows from operations, the L-D-X System must achieve a significant
degree of  market  acceptance among  health  care providers  in  the  monitoring
market,  particularly POLs. The substantial majority of diagnostic tests used by
physicians and other health care providers are performed by independent clinical
laboratories and hospital-based laboratories.  Physicians and other health  care
providers  will not  use the L-D-X  System unless  they determine that  it is an
attractive alternative to other means of screening or monitoring blood  detected
diseases,  particularly  independent  clinical  laboratories  and hospital-based
laboratories, and that  the clinical benefits  to the patient  and cost  savings
achieved  through use of the L-D-X System  outweigh the cost of the system. Such
determination will depend, in  part, upon the L-D-X  System's accuracy, ease  of
use,  rapid test time, reliability, cost effectiveness, portability and level of
third party  reimbursement.  Even if  the  advantages  of the  L-D-X  System  in
diagnosing  and monitoring patients with blood detected diseases are established
as clinically significant,  physicians, medical clinics,  pharmacists and  other
health care providers may elect not to purchase and use the L-D-X System for any
number of other reasons. For example, physicians and other health care providers
may  not change their established means of  having such tests performed, may not
make the necessary investment to purchase  the Company's products or may not  be
able  to  obtain  adequate  reimbursement  from  third  party  payors  for tests
performed using the L-D-X System. In addition, the growing prevalence of managed
care and health maintenance organizations may adversely affect the POL market. A
growing number  of  physicians are  salaried  employees and  have  no  financial
incentive  to  perform testing.  Many HMO  and  managed care  organizations have
contracts with laboratories which  require participating or employed  physicians
to  send patient specimens  to contracted laboratories.  Finally, physicians are
under growing pressure by Medicare and  private insurers to limit their  testing
to  "medically necessary" tests. As  a result of these  and other factors, there
can be  no assurance  that demand  for  the L-D-X  System, particularly  in  the
monitoring market, will be sufficient to allow for profitable operations.
 
  PRODUCTS UNDER DEVELOPMENT
 
    The  Company's strategy is to use the technological flexibility of the L-D-X
System to develop new cassettes that address disease states and testing  markets
the Company believes provide attractive commercial opportunities. The Company is
in  the early stages of  developing new cassettes that  would expand its product
line in the screening market and would better position its product line for  the
POL  market.  To date,  the  Company has  been  engaged primarily  in conducting
research and development to  determine the feasibility  of performing these  new
tests  on  the L-D-X  System.  The Company  will  initially focus  its available
resources on the development of uric  acid, blood urea nitrogen, creatinine  and
liver  enzyme tests, as well as the immunoassay-based test to detect and monitor
metabolic bone diseases and disorders being developed in conjunction with  Metra
Biosystems.  The  Company will  undertake  the development  of  additional tests
depending on the progress of its existing development efforts and its  available
resources.  To  complete  its product  development  programs,  particularly with
 
                                       9
<PAGE>
respect to the  immunoassays, the Company  may be required  to develop new  core
technologies,  processes and production equipment.  In addition, the Company may
also be required to retain additional scientific, engineering and  manufacturing
staff.  There  can  be no  assurance  that  the Company  will  be  successful in
developing any of the tests described below, or even if successfully  developed,
that  such tests  will receive  regulatory clearance,  be capable  of being cost
effectively manufactured  in sufficient  quantities, on  a timely  basis and  in
compliance  with regulatory guidelines, or be successfully marketed. The Company
intends to design and develop  most of these products so  as to be eligible  for
FDA  510(k) clearance and  waivers under CLIA  (See "-- Government Regulation"),
although there can be no assurance that the Company's products under development
will obtain such clearances or waivers.
 
    Products currently being developed by the Company are described below.
 
    METABOLIC BONE DISEASES AND DISORDERS.  Osteoporosis is the most  widespread
form  of bone disease characterized by a general loss of bone density. This loss
of bone density can  lead to a  weakening of the bone,  thereby making the  bone
more  prone to fractures. Biological markers  of bone metabolism are secreted in
urine, and it  has been  shown that  the level  of secretion  correlates to  the
amount of bone loss. The measured levels of these markers has also been shown to
be  responsive to osteoporosis therapies  such as hormone replacement. According
to the National Osteoporosis Foundation,  this disease afflicts over 25  million
Americans  and  over  200  million  people  worldwide.  In  the  United  States,
approximately 1.5 million  osteoporosis related fractures  occur each year.  For
Caucasian women, it is estimated that the risk of hip fractures approximates the
combined  risks of  breast, endometrial  and ovarian  cancers. The  World Health
Organization estimates that the  cost of osteoporosis  related fractures in  the
United States exceeds $7 billion annually.
 
    The  Company has entered into an  agreement with Metra Biosystems to develop
and  market  Metra  Biosystems'  Pyrilinks-D  and  other  related  bone   marker
technologies  on the L-D-X System. The Company has successfully demonstrated the
feasibility of meeting the initial  specifications for the Company's  technology
for  this  urine-based  immunoassay test  on  the  L-D-X System  and  is  in the
prototype stage of development. See "-- Strategic Relationships."
 
    RENAL FUNCTION TESTS.  The Company  is developing a menu expansion of  tests
to  include tests for uric acid, blood urea nitrogen and creatinine for the POL.
The Company believes that these tests are among the most commonly ordered  tests
in  physician offices. Uric acid  elevations occur in renal  diseases as well as
gout, and low uric acid levels are sometimes associated with diabetes and severe
liver disease. Blood urea nitrogen elevations occur in chronic renal disease  as
well  as urinary  tract obstruction.  Blood urea  nitrogen is  useful to monitor
hemodialysis and other therapies. Creatinine is also a measure of renal function
and is used  in combination with  uric acid  and blood urea  nitrogen tests.  In
addition,  creatinine is used  as a measure  of renal blood  flow which may have
become reduced due  to congestive heart  failure or dehydration.  Low levels  of
creatinine  may  result  from  decreased hepatic  production  in  advanced liver
disease. The Company  is currently  conducting feasibility studies  for each  of
these tests.
 
    PROSTATE SPECIFIC ANTIGEN (PSA).  The American Cancer Society estimates that
in  1996, 317,000 Americans will be  diagnosed with prostate cancer and predicts
that deaths from  prostate cancer in  the United States  will reach over  41,000
making it the second leading cause of cancer related deaths. The American Cancer
Society  recommends that men 50 and older  receive a PSA blood test annually. By
making early detection  possible, treatment  can begin  when there  is a  higher
likelihood  of success, leading  to better survival rates  from the disease. The
Company has demonstrated the feasibility of measuring PSA from a single drop  of
whole  blood using  the Company's technology.  The Company expects  that the PSA
test may require pre-market  approval ("PMA") from the  FDA. See "--  Government
Regulation."
 
    GLYCATED  HEMOGLOBIN.  Glycated hemoglobin measurement is used by physicians
to assess a  diabetic's long term  compliance with prescribed  diet and  insulin
usage.  This test  measures the  percent of  the patient's  hemoglobin which has
become   coupled    to    glucose.    A   relatively    high    percentage    of
 
                                       10
<PAGE>
hemoglobin  to  glucose indicates  poor patient  compliance,  which can  lead to
severe health problems. The American Diabetes Association ("ADA") recommends  at
least  semi-annual measurement for  all diabetic patients.  It is estimated that
there are seven to eight million diagnosed diabetics in the United States.
 
    The Company has  been notified by  the U.S. Department  of Health and  Human
Services  that it will  receive a "Small Business  Innovative Research" grant of
$100,000 to  further develop  this test  on  the L-D-X  System. The  Company  is
currently  evaluating the feasibility of a test to detect glycated hemoglobin on
the L-D-X System.
 
    OTHER PRODUCTS UNDER DEVELOPMENT.  The Company currently sells two cassettes
which can calculate LDL cholesterol levels from the combined readings of TC, HDL
and triglycerides. LDL cholesterol  is the fraction of  TC which leads to  heart
disease and is referred to as "bad" cholesterol. There is now available a direct
version  of the LDL test,  and the Company is  considering adapting this form of
the test  to the  L-D-X  System. The  advantage of  this  direct test  over  the
calculated  version of the test is that it  does not require the patient to fast
before testing. However, since lipid management requires the physician to assess
a patient treatment on  both "good" and "bad"  cholesterol, the disadvantage  of
the  stand alone direct  LDL test is the  lack of the  patient's HDL values. The
Company believes  that the  L-D-X  System may  overcome  this problem  with  its
ability to run multiple tests simultaneously on the system.
 
    The  Company is currently evaluating the feasibility of a test to detect the
levels of liver enzymes  in whole blood. Liver  enzymes are measures of  hepatic
damage  which may be caused by a  number of diseases and/or chemical toxicities.
The ability to monitor the levels of liver enzymes is important because a  large
number  of drugs, including cholesterol lowering  drugs, can cause liver damage.
The Company  believes  that a  liver  enzyme  test would  complement  its  lipid
diagnostic products.
 
    Lp(a)  is a lipoprotein which is a component of LDL. It has been established
in the scientific literature  that Lp(a) is a  risk factor for  atherosclerosis,
and  it is believed that Lp(a) may be  the component of LDL which is responsible
for the risk associated with LDL. The Company believes that a test for Lp(a) may
emerge as the  dominate test for  cardiac risk  in the future.  The Company  has
licensed  the rights to  a new technology  to measure Lp(a).  This technology is
currently being evaluated by the Company and a number of collaborators.
 
    The Company believes that its revenue growth and profitability will  depend,
in  part, upon its ability to complete development of and successfully introduce
these new tests. In addition, some of these new tests depend on the  development
of  immunoassay-based technologies  and the incorporation  of these technologies
into the L-D-X System. The Company will be required to undertake  time-consuming
and  costly development  activities and seek  regulatory approval  for these new
tests. There can  be no  assurance that  the Company  will be  able to  complete
successful  development of any of these  future products. Furthermore, there can
be no assurance that even if these products and/or any other future products are
successfully developed, the  Company will  be able to  successfully receive  FDA
clearance  or  approval or  CLIA  waivers on  a  timely basis,  manufacture such
products on a cost effective basis and in compliance with applicable  regulatory
standards,  or successfully market these products.  If the Company is unable for
technological or other  reasons to  complete the  development, introduction  and
scale up of manufacturing of any new tests or if such new tests do not achieve a
significant  level  of  market  acceptance,  the  Company's  business, financial
condition and results of operations could be materially adversely affected.
 
SALES AND MARKETING
 
    To date,  the  Company  has  focused its  sales  and  marketing  efforts  on
hospitals,   managed  care  organizations,   large  physician  group  practices,
corporate wellness programs, community health centers, health promotion  service
providers  and other  independent screeners  in the  screening market.  With the
recent CLIA waiver of  its existing product line,  the Company believes that  it
has a significant
 
                                       11
<PAGE>
opportunity  to access the monitoring market. The Company utilizes a combination
of a direct  sales force and  regional distributors to  sell into the  screening
market  and  is  developing  a  national  distribution  network  to  access  the
monitoring market.
 
    The Company  provides continuing  customer support,  including an  automated
order  entry system, and  technical support whenever  needed to promote customer
satisfaction. A U.S.  toll-free number  gives the customer  immediate access  to
Cholestech's  in-house customer  service and  technical support  group. Customer
service  representatives   also  assist   customers  to   order  cassettes   and
accessories.  The Company  maintains an  in-house instrument  service capability
that provides repairs  to instruments either  under warranty or  on a parts  and
labor basis.
 
  SCREENING MARKET
 
    The Company's distribution strategy for the screening market is to sell both
directly  to high  volume customers and  to selected  regional distributors. The
Company believes  that  its products  provide  a  cost effective,  easy  to  use
alternative  for preventive health care programs that are focused on identifying
high risk  individuals with  possible cardiovascular  disease and  diabetes  and
enrolling  them into appropriate  disease intervention programs  to reduce their
overall health risk.
 
    The Company sells directly through a  field sales group which includes  nine
regional   sales  managers.   In  addition,   the  Company   has  established  a
telemarketing effort to support large volume customers and utilizes direct  mail
campaigns to increase demand for its products. The Company also has entered into
agreements  with nine  regional distributors  that augment  the Company's direct
sales efforts.
 
    The Company's international distribution  strategy for the screening  market
is  designed  to opportunistically  penetrate  targeted geographical  markets by
selling directly  to individual  distributors in  those areas.  The Company  has
entered  into  agreements with  several foreign  distributors to  distribute the
L-D-X System primarily in  Europe and Latin America  and is negotiating  similar
agreements with other distributors in South and Central America.
 
  MONITORING MARKET
 
    The  Company's sales  and marketing  efforts in  the monitoring  market will
initially be focused on the POL and pharmacy segments. To efficiently access the
54,000 POLs,  the Company  is  negotiating with  several national  and  regional
distributors.  As  of  April  1,  1996, the  Company  entered  into  a national,
non-exclusive distribution  agreement  with  PSS, a  national  medical  products
distributor with more than 700 sales professionals who focus on the POL market.
 
    The pharmacy market consists of 68,000 pharmacies which may provide point of
care testing. The Company believes that marketing success in the pharmacy market
will   be  dependent  upon  the   development  of  patient  monitoring  programs
implemented in conjunction with managed care providers and physicians on a local
basis. In  January  1996,  the  American  Pharmaceutical  Association  announced
Project  IMPACT (IMprove Persistence And  Compliance to Therapy). Project IMPACT
is being  funded  by Merck,  and  its goal  is  to demonstrate  the  ability  of
pharmacists   to  enhance  patient  outcomes  with  drug  therapy  and  behavior
modification. The pilot program enlarges the  pharmacist's role to one in  which
the  pharmacist monitors  therapeutic effectiveness of  medications and provides
counseling services  to  the  patient. Utilizing  pharmacists  to  provide  such
services  may result in both direct and indirect cost savings to the patient and
the patient's insurer. The  Company is participating  in Project IMPACT  through
the  use  of  its  L-D-X  System  to  monitor  patients  in  this pharmacy-based
cholesterol management project. The  Company intends to  utilize the program  to
evaluate  the potential market  for the L-D-X  System among pharmacists. Project
IMPACT will monitor approximately 900 patients at 32 community-based  pharmacies
across the country for a period of two years.
 
    In order for the Company to increase revenues and achieve profitability, the
L-D-X System must achieve a significant degree of market acceptance among health
care providers in the monitoring market, particularly POLs. The Company has only
limited experience marketing and selling to the
 
                                       12
<PAGE>
monitoring  market in the  United States. The Company  has only recently entered
into a  distribution arrangement  with  such a  national distributor,  PSS.  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  PSS or  that  the Company  will be  able  to enter  into  and
maintain arrangements with additional distributors on a timely basis, if at all.
There  can  be no  assurance  that the  Company will  be  able to  penetrate the
monitoring market, including the  POL or pharmacy  segments, or that  physicians
will  use the L-D-X System instead of  clinical laboratory services for the same
tests.
 
    In addition, in order to increase  sales and market acceptance of the  L-D-X
System,  the Company will also be required  to expand its direct sales force and
marketing organization. Establishing a sales and marketing capability sufficient
to support the level of sales necessary for the Company to attain  profitability
will  require  substantial  efforts  and  significant  management  and financial
resources. The Company is currently actively recruiting a new executive  officer
to replace the Company's former Executive Vice President of Marketing and Sales,
who  resigned in April 1996. There can be  no assurance that the Company will be
able to recruit and retain direct sales and marketing personnel, in particular a
new executive officer  of sales and  marketing, in  order to build  a sales  and
marketing  organization, that building  such a sales  and marketing organization
will be cost effective or that the Company's sales and marketing efforts will be
successful.
 
STRATEGIC RELATIONSHIPS
 
    The Company's  strategy  includes establishing  strategic  relationships  to
develop  new products,  expand its customer  base, and provide  the Company with
technological, clinical, marketing, financial and other key resources.
 
    In May 1996, the Company entered into a development, marketing and licensing
agreement  with  Metra  Biosystems  to  develop  an  immunoassay  test  cassette
incorporating  Metra Biosystems' bone resorption technology  to be used with the
L-D-X System.  Pursuant  to the  agreement,  Metra Biosystems  purchased  39,526
shares of the Company's Common Stock for an aggregate purchase price of $250,000
($6.325 per share) and is obligated to purchase $750,000 of additional shares of
Common  Stock upon  the completion of  specified milestones by  the Company. The
Company has  granted Metra  Biosystems registration  rights in  connection  with
Metra Biosystems' purchase of the Company's Common Stock.
 
    In  connection with the development of  the immunoassay test cassette, Metra
Biosystems granted Cholestech a  non-exclusive, royalty-bearing license to  use,
make, sell, offer to sell, import or distribute the resulting cassette to assess
bone resorption, a gauge of the effectiveness of treatments of certain metabolic
diseases  and  disorders  and  certain  future  products  worldwide  (the "Metra
License"). The Company is obligated to pay royalties to Metra Biosystems on  the
bone  resorption product and on products that  stem from work done in the course
of the collaboration but do not incorporate any of Metra Biosystems' proprietary
technology. The  parties will  negotiate royalties  on future  Metra  Biosystems
products  as  appropriate.  Under the  agreement,  the Company  will  market the
immunoassay test  through  its  existing distribution  channels  in  the  United
States.  The  Company and  Metra  Biosystems will  work  together to  market and
distribute the tests internationally.
 
    There can be no assurance that the Company will be successful in  developing
a  bone resorption  test or  any other product  under this  agreement, that this
agreement will not expire prior  to its term, or that  even if any products  are
developed  that they will be successfully marketed. The Company expects to enter
into additional strategic agreements in the future to develop, commercialize and
sell its current and future products. There can be no assurance that the Company
will be able  to negotiate  acceptable agreements in  the future,  or that  such
relationships  will be successful.  In addition, there can  be no assurance that
the  Company's  strategic  partners   will  not  pursue  alternative   competing
technologies or products.

MANUFACTURING
 
    The  Company manufactures,  tests, performs quality  assurance, packages and
ships  products  at  its  30,000  square  foot  facility  located  in   Hayward,
California. The Company maintains control of those portions of the manufacturing
process  that it believes are complex and provide important barriers to entry by
competitors. The production  processes employed  by the  Company to  manufacture
cassettes  differ significantly  from those employed  in the  manufacture of the
analyzer.
 
  MANUFACTURE OF CASSETTES
 
    The Company  purchases chemicals,  membranes and  other raw  materials  from
third  party  suppliers  and  converts these  raw  materials,  using proprietary
processes, into cassettes.  The Company believes  its proprietary processes  and
custom-designed equipment are important components of its cassette manufacturing
operations. The Company has developed core manufacturing technologies, processes
and  production machinery, including  (i) membrane lamination  and welding; (ii)
discrete membrane  impregnation; (iii)  on-line calibration;  and (iv)  software
control of the manufacturing process. The Company is currently in the process of
completing  validation of the second cassette manufacturing line and expects the
line to  be fully  operational in  mid-1996. In  the event  that cassette  sales
volume  significantly increases,  the Company would  be required  to construct a
third cassette manufacturing line. There can be no assurance that such expansion
of cassette manufacturing  capacity can  be completed  in a  timely fashion,  if
ever,  and the  failure to  increase cassette  manufacturing capacity  on a cost
effective and timely basis would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    Manufacturing of the  cassettes is highly  complex and sensitive  to a  wide
variety  of factors, including  variations and impurities  in the raw materials,
performance of the manufacturing equipment and the level of contaminants in  the
manufacturing  environment.  Incoming  inspection of  raw  materials, in-process
controls, improved  manufacturing  equipment performance,  and  better  operator
proficiency  and training  all contribute  to improvements  in yield. Continuous
improvement of process factors are key determinants of manufacturing output  and
efficiency,  product quality and reliability and overall profitability. Although
the Company believes that it has  acceptable cassette yields and should be  able
to  maintain the current cassette yield in the future, there can be no assurance
that such improvement  will be maintained  or that the  Company will not  suffer
future  periodic  cassette yield  problems in  connection  with new  or existing
products. Failure to maintain  the improvements in process  yield or failure  to
obtain acceptable yields on future products could have a material adverse effect
on  the Company's business. The Company's cassette manufacturing lines represent
a single point of potential failure  in its manufacturing process that would  be
costly  and  time  consuming to  replace  if their  operation  were interrupted.
Furthermore, the Company  has a  limited number  of employees  dedicated to  the
operation  and maintenance of the cassette  manufacturing equipment, the loss of
whom could impact the Company's ability to effectively operate and service  such
equipment.  The interruption of cassette manufacturing operations or the loss of
employees dedicated to the cassette manufacturing facility could have a material
adverse effect on  the Company's  business, financial condition  and results  of
operations.  The  Company  manufactures all  of  the cassettes  at  its Hayward,
California manufacturing facility, and any  prolonged inability to utilize  such
facility  as a  result of  earthquake, fire or  otherwise would  have a material
adverse effect on  the Company's  business, financial condition  and results  of
operations.
 
  MANUFACTURE OF L-D-X ANALYZER
 
    The  analyzer employs a variety of  subassemblies and components designed or
specified by the Company, including an optical element, microprocessors, circuit
boards,  a  liquid  crystal  display  and  other  electrical  components.  These
components  and subassemblies are manufactured by a variety of third parties and
are shipped to the Company for final assembly. The Company's manufacture of  the
 
                                       14
<PAGE>
analyzer  consists  primarily of  assembly,  testing, inspection  and packaging.
Testing consists of  a burn-in  period, functional tests  and integrated  system
testing  using specially  produced test cassettes.  The Company  believes it can
expand its current analyzer manufacturing capacity at minimal cost.
 
  RAW MATERIALS; QUALITY ASSURANCE
 
    Outside vendors provide  Cholestech with subassemblies,  components and  raw
materials.  These materials are purchased, inspected and tested by the Company's
quality control personnel. The Company's quality control personnel also  perform
finished  goods quality  control and  inspection and  maintain documentation for
compliance  with   cGMP   and  other   government   manufacturing   regulations.
Cholestech's  manufacturing  facilities are  subject  to periodic  inspection by
regulatory authorities. See "--  Government Regulation." Certain key  components
and  raw  materials used  in  the manufacturing  of  the Company's  products are
currently provided by single-source vendors  pursuant to the Company's  periodic
purchase  orders. The  Company believes that  it maintains an  adequate level of
such components and  raw materials  in inventory and  believes that  alternative
sources for such components and raw materials are available. However, any supply
interruption  in a sole-sourced component or  raw material would have a material
adverse effect on  the Company's  business once  the inventory  is depleted  and
until  a  new  source of  supply  were  qualified. 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 business.  Because the  Company is  a
small  customer of  many of its  suppliers, there  can be no  assurance that its
suppliers will devote adequate resources to supplying the Company's needs.
 
COMPETITION
 
    The testing market in which  the Company competes is intensely  competitive.
The  Company's competition consists mainly  of independent clinical laboratories
and hospital-based laboratories, as well as with manufacturers of bench top  and
other point of care analyzers. The substantial majority of diagnostic tests used
by  physicians  and  other  health care  providers  are  currently  performed by
clinical laboratories and hospital-based laboratories. The Company expects  that
these  laboratories will  compete intensely to  maintain their  dominance in the
monitoring market. In  order to achieve  broad market acceptance  for the  L-D-X
System,  the Company will be required to demonstrate that the L-D-X System is an
attractive alternative to the independent clinical laboratory and hospital-based
laboratory. This will require  physicians to change  their established means  of
having  such tests performed.  There can be  no assurance that  the L-D-X System
will  be  able  to  compete  with   the  testing  services  provided  by   these
laboratories.
 
    In  addition,  companies having  a  significant presence  in  the diagnostic
market, such as Abbott Laboratories, Clinical Diagnostic Systems, a division  of
Johnson  and Johnson which was formerly a division of Eastman Kodak Company, and
Boehringer Mannheim, have  developed or  are developing  analyzers targeted  for
point   of  care.  These  competitors   have  substantially  greater  financial,
technical, research and other resources and larger, more established  marketing,
sales,  distribution and  service organizations  than the  Company. In addition,
such competitors offer broader product lines than the Company, have greater name
recognition than the Company, and offer  discounts as a competitive tactic.  The
Company  believes  that  it  currently  has  a  competitive  advantage  with the
classification of  its  existing products  as  waived under  CLIA.  The  Company
expects  that the reclassification of the L-D-X System as waived under CLIA will
result in  competitors  seeking to  develop  products that  qualify  for  waived
classification.  There can be  no assurance that  the Company's competitors will
not succeed in obtaining CLIA waived status for their products or in  developing
or  marketing technologies or products that  are more effective and commercially
attractive than the Company's current or  future products, or that would  render
the Company's technology or products obsolete or noncompetitive.
 
    The  Company's products must  compete effectively overall  with the existing
and future products of its competitors primarily on the basis of the ability  to
perform tests at point of care, ease of use,
 
                                       15
<PAGE>
testing  of multiple  analytes from  a single  sample, ability  to conduct tests
without a skilled technician or a blood pretreatment step, the breadth of  tests
available, market presence, cost effectiveness, precision, accuracy or immediacy
of  results. There can be no assurance  that the Company will have the financial
resources,  technical   expertise   or  marketing,   distribution   or   support
capabilities to compete successfully in the future. See "Business -- Products --
Products Under Development," "-- Technology" and "-- Competition."
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
    The  Company pursues  an active patenting  policy to  protect inventions and
technology which are important  to its business. The  Company owns eight  United
States  patents covering various  aspects of the  technology incorporated in its
products, including the method for separating  HDL from other lipoproteins in  a
dry  chemistry format, the  basic design of  the testing cassette  and the L-D-X
Analyzer and the  method of correcting  for the effects  of substances that  can
interfere  with testing  of a  blood sample. The  Company has  also filed patent
applications  relating  to  its  technology  internationally  under  the  Patent
Cooperation  Treaty and individual foreign applications. The Company is also the
licensee of one United States patent relating to the measurement of Lp(a) and  a
number of third party patents relating to its cassette technology.
 
    The medical products industry has been characterized by extensive litigation
regarding  patents  and other  intellectual property  rights, and  any potential
litigation can  result in  substantial  loss or  diversion  of revenues  of  the
Company and could have a material adverse effect on the Company. There can be no
assurance that pending patent applications filed by the Company will be approved
or  that the issued or pending patents will not be challenged or circumvented by
competitors. Notwithstanding the Company's active pursuit of patent  protection,
the  Company believes  that its  future success  will depend  primarily upon the
technical expertise, creative skills and  management abilities of its  officers,
directors and key employees rather than on patent ownership.
 
    There  can be no assurance that infringement  claims will not be asserted by
other parties in the future, that in such event the Company will prevail or that
it will be able to obtain  licenses on reasonable terms. Adverse  determinations
in  any litigation could  subject the Company  to significant liabilities and/or
require the  Company to  seek licenses  from third  parties. If  the Company  is
unable  to  obtain  necessary licenses  or  is  unable to  develop  or implement
alternative technology, the Company  may be unable to  manufacture and sell  the
affected products. Any of these outcomes could have a material adverse effect on
the Company's business.
 
    The  Company relies substantially  on trade secrets,  technical know-how and
continuing invention  to  develop and  maintain  its competitive  position.  The
Company works actively to foster continuing technological innovation to maintain
and  protect  its  competitive  position, and  the  Company  has  taken security
measures to protect its trade secrets and periodically explores ways to  further
enhance trade secret security. There can be no assurance that such measures will
provide adequate protection for the Company's trade secrets or other proprietary
information.  Although  the  Company has  entered  into  proprietary information
agreements with  its  employees,  consultants  and advisors,  there  can  be  no
assurance  that these  agreements will  have adequate  remedies for  any breach.
There can be no assurance that the Company's competitors will not  independently
develop  substantially  equivalent  proprietary  information  and  techniques or
otherwise  gain  access  to  the  Company's  trade  secrets  or  disclose   such
technology,  or that the Company can meaningfully protect its right to its trade
secrets.
 
GOVERNMENT REGULATION
 
  FDA AND OTHER REGULATIONS
 
    The manufacture and sale of the Company's products are subject to regulation
by numerous governmental  authorities, principally  the United  States Food  and
Drug Administration ("FDA") and
 
                                       16
<PAGE>
corresponding  state and  foreign regulatory  agencies. Pursuant  to the Federal
Food, Drug  and Cosmetic  Act  of 1938,  as amended  (the  "FDC Act"),  the  FDA
regulates   the  clinical  testing,   manufacture,  labeling,  distribution  and
promotion of  medical devices.  Noncompliance with  applicable requirements  can
result  in, among other  things, fines, injunctions,  civil penalties, recall or
seizure of products, total or partial  suspension of production, failure of  the
government  to  grant premarket  clearance  or premarket  approval  for devices,
withdrawal of marketing approvals, a recommendation by the FDA that the  Company
not  be permitted to  enter into government  contracts and criminal prosecution.
The FDA also has the authority to  request repair, replacement or refund of  the
cost of any device manufactured or distributed by the Company.
 
    In  the  United States,  medical devices  are classified  into one  of three
classes, Class I, II or III, on the  basis of the controls deemed by the FDA  to
be  necessary  to  reasonably ensure  their  safety and  effectiveness.  Class I
devices are subject to general  controls (e.g. labeling, premarket  notification
and adherence to cGMPs). Class II devices are subject to general controls and to
special  controls (e.g. performance  standards, postmarket surveillance, patient
registries, and FDA  guidelines). Generally,  Class III devices  are those  that
must  receive  premarket  approval  by  the  FDA  to  assure  their  safety  and
effectiveness (e.g. life-sustaining, life-supporting and implantable devices, or
new devices  which  have not  been  found substantially  equivalent  to  legally
marketed   devices),  and  require   clinical  testing  to   assure  safety  and
effectiveness and FDA approval prior to marketing and distribution.
 
    Before a new device can be introduced into the market, the manufacturer must
generally obtain  marketing clearance  through a  pre-market notification  under
Section  510(k) of the FDC Act or an approval of a PMA application under Section
515 of  the  FDC Act.  A  510(k) clearance  typically  will be  granted  if  the
submitted  information establishes  that the  proposed device  is "substantially
equivalent" to a legally marketed Class I or II medical device or to a Class III
medical device for which the FDA has not called for PMAs. A 510(k)  notification
must  contain information to  support a claim  of substantial equivalence, which
may include laboratory test  results or the results  of clinical studies of  the
device in humans. It generally takes from four to twelve months from the date of
submission  to  obtain  a 510(k)  clearance,  but  it may  take  longer.  A "not
substantially equivalent" determination by the FDA, or a request for  additional
information,  could delay the market introduction of new products that fall into
this category. For  any devices  that are  cleared through  the 510(k)  process,
modifications   or  enhancements  that  could  significantly  affect  safety  or
effectiveness, or constitute a major change  in the intended use of the  device,
will  require new 510(k)  submissions. The L-D-X Analyzer  and all existing test
cassettes required that the Company  obtain 510(k) clearance prior to  marketing
in the United States.
 
    In  general,  the Company  intends  to develop  and  market tests  that will
require no more than 510(k) clearance. However, if the Company cannot  establish
that  a proposed test cassette is substantially equivalent to a legally marketed
device, the Company must seek pre-market approval of the proposed test  cassette
from the FDA through the submission of a PMA application. Certain products under
development,   including  the  PSA  test,  may   require  submission  of  a  PMA
application. A PMA  application generally  must be supported  by extensive  data
including,  laboratory, preclinical and clinical  data to demonstrate safety and
efficacy, as well as  a complete description of  the device and its  components,
and  a  detailed description  of the  methods, facilities  and controls  used to
manufacture the device. In  addition, the submission  must include the  proposed
labeling,  advertising  literature  and  training  methods  (if  required). Upon
receipt of a  PMA application,  the FDA makes  a threshold  determination as  to
whether the application is sufficiently complete to permit a substantive review.
If  the  FDA determines  that the  PMA application  is sufficiently  complete to
permit a substantive review, the FDA will accept the application for filing. The
PMA approval process can be lengthy, expensive and uncertain. An FDA review of a
PMA application  generally  takes one  to  three years  from  the date  the  PMA
application is accepted for filing, but may take significantly longer.
 
    Any  products manufactured  or distributed  by the  Company pursuant  to FDA
clearance or approvals are subject to pervasive and continuing regulation by FDA
and certain state agencies, including record keeping requirements and  reporting
of    adverse   experience    with   the    use   of    the   device.   Labeling
 
                                       17
<PAGE>
and promotional  activities are  subject  to scrutiny  by  FDA and,  in  certain
circumstances,  by the Federal Trade  Commission. Current FDA enforcement policy
prohibits the marketing of approved medical devices for unapproved uses.
 
    The FDC  Act  regulates  the Company's  quality  control  and  manufacturing
procedures   by  requiring  the  Company   and  its  contract  manufacturers  to
demonstrate compliance  with  cGMP.  The  FDA  monitors  compliance  with  these
requirements by requiring manufacturers to register with the FDA, which subjects
them  to  periodic  inspections. While  the  Company's  manufacturing processes,
facilities and  practices  have not  been  inspected  by the  FDA,  the  Company
believes that its manufacturing practices are in compliance with cGMP. The State
of California also regulates and inspects Cholestech's manufacturing facilities.
The  Company has been inspected twice by the  State of California to date and is
manufacturing under an issued medical device manufacturers facility license from
the State of California. If violations  of the applicable regulations are  noted
during  an FDA or State of  California inspection of the Company's manufacturing
facilities or the  manufacturing facilities of  its contract manufacturers,  the
continued marketing of the Company's product could be adversely affected.
 
    The  Company and  its products are  also subject  to a variety  of state and
local laws and regulations in those states or localities where its products  are
or  will be  marketed. Any  applicable state  or local  laws or  regulations may
hinder the  Company's  ability  to  market  its  products  in  those  states  or
localities.
 
    The  Company  is also  subject  to numerous  federal,  state and  local laws
relating to such  matters as safe  working conditions, manufacturing  practices,
environmental  protection,  fire hazard  control  and disposal  of  hazardous or
potentially hazardous substances.  There can  be no assurance  that the  Company
will  not be required  to incur significant  costs to comply  with such laws and
regulations now or in the future or that such laws or regulations will not  have
a material adverse effect upon the Company.
 
    Changes in existing requirements or adoption of new requirements or policies
could  increase the  cost of  or otherwise adversely  affect the  ability of the
Company  to  comply  with  regulatory  requirements.  Failure  to  comply   with
regulatory requirements could have a material adverse effect on the Company.
 
  CLIA REGULATIONS
 
    The  use of the Company's products in  the United States is subject to CLIA,
which provides for federal  regulation of laboratory  testing, an activity  also
regulated  by  most  states.  Laboratories  either  must  obtain  a registration
certificate from HCFA, register with an approved accreditation agency or  obtain
a  state license in a state with  a federally approved license program. The CLIA
regulations seek to  ensure the quality  of medical testing  and generally  took
effect  in September 1992 with a  two-year phase-in of certain requirements. The
three primary  mechanisms to  accomplish  this goal  are daily  quality  control
requirements  to  ensure  the  accuracy of  laboratory  devices  and procedures,
proficiency testing  to measure  testing accuracy,  and personnel  standards  to
assure   appropriate  training  and  experience  for  laboratory  workers.  CLIA
categorizes tests  as "waived,"  or  as being  "moderately complex"  or  "highly
complex" on the basis of specific criteria.
 
    Prior  to January 1996,  the L-D-X System,  including all current cassettes,
was categorized under  CLIA as moderately  complex. In January  1996, the  L-D-X
System  and the TC, HDL, Triglycerides and Glucose tests in any combination were
reclassified as waived under  CLIA. Under the  waived classification, users  are
only  required to obtain a  certificate of waiver from HCFA  and pay a $100 fee.
This certificate must be  renewed every two years.  Current L-D-X System  users,
including  managed  care organizations,  hospitals, self-insured  businesses and
health promotion organizations, will now  be able to use  the L-D-X System at  a
lower  cost. The Company provides United  States purchasers of its products with
the documentation, systems  and support  necessary for the  purchaser to  comply
with  CLIA. In order to successfully  commercialize the tests that are currently
under development, the
 
                                       18
<PAGE>
Company believes that it  will be critical to  obtain waived classification  for
such tests under CLIA. There can be no assurance that any new tests developed by
the  Company will qualify for the waived  classification. Any failure of the new
tests to obtain  waived status under  CLIA will adversely  impact the  Company's
ability  to commercialize such tests, which could have a material adverse effect
on the Company's  business, financial  condition and results  of operations.  In
addition,  there can be  no assurance that  any future amendment  of CLIA or the
promulgation of  additional regulations  impacting laboratory  testing will  not
have  an adverse effect on the Company's  ability to market the L-D-X System. If
CLIA regulations were modified in a manner that reduced regulatory  requirements
and  burdens faced  by competitive  products, any  competitive advantage  of the
L-D-X System's waived status would be reduced or eliminated.
 
THIRD PARTY REIMBURSEMENT
 
    In  the  United  States,  health  care  providers,  such  as  hospitals  and
physicians,  that purchase  diagnostic products,  including the  Company's L-D-X
System, generally  rely  on  third  party  payors,  principally  private  health
insurance  plans, federal Medicare and state  Medicaid, to reimburse all or part
of the cost of the procedure in  which the product is being used. The  Company's
ability  to commercialize  its products successfully  in the  United States will
depend in  part on  the  extent to  which reimbursement  for  the cost  of  such
products  and  related  treatment  will  be  available  from  government  health
administration  authorities   (such   as   HCFA,   which   determines   Medicare
reimbursement  levels), private  health insurers  and other  organizations. Such
third party payors can affect the pricing or the relative attractiveness of  the
Company's products by regulating the maximum amount of reimbursement provided by
such  payors for testing services. Reimbursement  is currently not available for
certain uses  of the  Company's products.  For example,  the cost  of the  L-D-X
Analyzer  is generally not subject to reimbursement by government or other third
party payors. In  addition, the  tests performed by  public health  departments,
corporate wellness programs and other large volume users in the screening market
are  generally not  subject to reimbursement.  In addition,  certain health care
providers are  moving towards  a managed  care system  in which  such  providers
contract  to provide  comprehensive health  care for  a fixed  cost per patient.
Managed care providers  are attempting  to control the  cost of  health care  by
authorizing  fewer  elective  procedures,  such as  screening  of  blood disease
levels. The  Company is  unable to  predict what  changes will  be made  in  the
reimbursement  methods  utilized by  third party  payors.  The Company  could be
adversely affected  by  changes in  reimbursement  policies of  governmental  or
private  health care payors, particularly to  the extent any such changes affect
reimbursement for procedures  in which  the Company's products  are used.  Third
party  payors are increasingly  scrutinizing and challenging  the prices charged
for medical products and services. Decreases in reimbursement amounts for  tests
performed using the Company's products may decrease amounts physicians and other
practitioners  are able to  charge patients, which in  turn may adversely affect
the Company's ability  to sell its  products on a  profitable basis. Failure  by
physicians  and other users to obtain  reimbursement from third party payors, or
changes  in  government  and  private   third  party  payors'  policies   toward
reimbursement  of tests employing  the Company's products  could have a material
adverse effect  on the  Company's business.  Given the  efforts to  control  and
reduce  health care costs in the United States  in recent years, there can be no
assurance that currently available levels  of reimbursement will continue to  be
available,  or that adequate  reimbursement will be available  in the future for
the Company's existing products or products under development. See "Risk Factors
- -- Uncertainty Relating to Third Party Reimbursement."
 
    Effective October 1, 1991,  HCFA adopted new  regulations providing for  the
inclusion  of  capital-related costs  in the  prospective payment  system, under
which providers are reimbursed on a
per-diagnosis  basis  at  fixed  rates  unrelated  to  actual  costs,  based  on
diagnostic  related groups (DRGs). Under this system of reimbursement, equipment
costs generally will not be reimbursed separately, but rather, will be  included
in  a single, fixed-rate, per patient reimbursement. These regulations are being
phased in over a ten-year period,  and, although the full implications of  these
regulations  cannot yet be known, the  Company believes that the new regulations
will place more pressure on hospitals'
 
                                       19
<PAGE>
operating margins, causing them to limit capital expenditures. These regulations
could have  an  adverse effect  on  the Company  if  hospitals decide  to  defer
obtaining  medical equipment as a result of any such limitation on their capital
expenditures. The  Company is  unable  to predict  what  adverse impact  on  the
Company,  if any, additional government  regulations, legislation or initiatives
or changes by  other payors affecting  reimbursement or other  matters that  may
influence decisions to obtain medical equipment may have.
 
    In  addition, market acceptance  of the Company's  products in international
markets is dependent,  in part,  upon the availability  of reimbursement  within
prevailing  health care payment  systems. Reimbursement and  health care payment
systems in international markets vary significantly by country, and include both
government sponsored health care and private insurance.
 
    The Company believes that  the overall escalating  cost of medical  products
and  services has led to and will continue to lead to increased pressures on the
health care industry, both foreign and domestic, to reduce the cost of  products
and  services,  including  products offered  by  the  Company. There  can  be no
assurance as  to  either United  States  or  foreign markets  that  third  party
reimbursement   and  coverage  will  be  available  or  adequate,  that  current
reimbursement amounts  will  not be  decreased  in  the future  or  that  future
legislation,  regulation, or reimbursement  policies of third  party payors will
not otherwise adversely  affect the  demand for  the Company's  products or  its
ability to sell its products on a profitable basis.
 
PRODUCT LIABILITY AND INSURANCE
 
    Sale of the Company's products entails risk of product liability claims. The
medical  testing industry has historically been litigious, and the Company faces
financial exposure to  product liability  claims in the  event that  use of  its
products  result in personal injury. The Company also faces the possibility that
defects in the design or manufacture of its products might necessitate a product
recall. There can be  no assurance that the  Company will not experience  losses
due  to product liability claims or recalls in the future. The Company currently
maintains product liability insurance with  coverage limits of $5.0 million  per
occurrence  and $5.0  million annually  in the  aggregate, and  there can  be no
assurance that the coverage limits of  the Company's insurance policies will  be
adequate.  Such  insurance is  expensive,  difficult to  obtain  and may  not be
available in the  future on acceptable  terms, or  at all. No  assurance can  be
given  that product  liability insurance  can be maintained  in the  future at a
reasonable cost or in sufficient amounts  to protect the Company against  losses
due to liability. An inability to maintain insurance at an acceptable cost or to
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 has  liability insurance  covering its  property and  operations
with  coverage and deductible amounts and  exclusions which the Company believes
are customary for companies of its size in its industry. The Company's  personal
property  is insured  for up  to $4.0 million  and it  has comprehensive general
liability coverage of up to $5.0 million. In addition, the Company has  business
interruption insurance of up to $5.6 million. There can be no assurance that the
Company's  current insurance  coverage is  adequate or that  it will  be able to
maintain insurance  at  an  acceptable  cost or  otherwise  to  protect  against
liability.
 
EMPLOYEES
 
    As  of March  31, 1996, the  Company employed 79  full-time employees. There
were 33 employees  in sales, marketing  and administration and  42 employees  in
manufacturing  and 4 employees devoted to  research and development. The Company
seeks to  attract and  retain skilled  and experienced  employees with  directly
relevant  experience  in  the  fields  of interest,  although  there  can  be no
assurance that  it will  continue  to do  so  in the  future.  The loss  of  key
personnel or the inability to hire or retain
 
                                       20
<PAGE>
qualified personnel, in particular a new executive officer of sales could have a
material  adverse  effect on  the  Company's business,  financial  condition and
results of  operations.  None  of  the employees  is  covered  by  a  collective
bargaining  agreement, and management  considers relations with  employees to be
excellent.
 
ITEM 2.  PROPERTIES
 
    The Company leases a 30,000 square foot facility in Hayward, California. The
Company's facility contains approximately 5,000 square feet of laboratory space,
7,000 square feet of  manufacturing space and  approximately 18,000 square  feet
devoted to marketing and administrative and common areas. The Company's lease on
the  facility expires in the year 2000.  The Company believes that this facility
is adequate to meet its requirements through the expiration of its lease.
 
ITEM 3.  LEGAL PROCEEDINGS
 
    The Company is not a party to any legal proceedings.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF OPERATIONS AND FINANCIAL CONDITION OF CHOLESTECH
SHOULD  BE READ IN  CONJUNCTION WITH THE FINANCIAL  STATEMENTS AND NOTES THERETO
INCLUDED ELSEWHERE IN THIS  REPORT. SPECIAL NOTE:  CERTAIN STATEMENTS SET  FORTH
BELOW  CONSTITUTE "FORWARD-LOOKING STATEMENTS" WITHIN  THE MEANING OF THE REFORM
ACT. SEE  "SPECIAL NOTE  REGARDING  FORWARD-LOOKING STATEMENTS"  ON PAGE  2  FOR
ADDITIONAL FACTORS RELATING TO SUCH STATEMENTS.
 
GENERAL
 
    The  Company develops, manufactures and markets  a proprietary point of care
diagnostic system which  measures specific analytes  to detect various  diseases
and  disorders  within five  minutes using  a  single drop  of whole  blood. The
Company has experienced significant operating losses since inception and, as  of
March 31, 1996, had an accumulated deficit of $49.7 million. The Company has not
generated  significant  revenues to  date, and  there can  be no  assurance that
significant revenues will ever  be achieved. The  Company is developing  certain
additional tests designed to extend the L-D-X System's capabilities. The Company
believes  that  its future  growth will  depend,  in part,  upon its  ability to
complete development and  successfully introduce  these new  tests. The  Company
expects  to continue to  incur operating losses  as well as  negative cash flows
from operations as it expands product  research and development efforts for  new
test  panels,  pursues regulatory  clearances and  approvals, expands  sales and
marketing activities to address the monitoring market, and develops and  expands
manufacturing  capacity for  existing and new  test panels.  The development and
commercialization of the  new tests will  require additional development,  sales
and  marketing,  manufacturing and  other expenditures.  The required  level and
timing of  such  expenditures  will  impact the  Company's  ability  to  achieve
profitability and positive cash flows from operations.
 
RESULTS OF OPERATIONS
 
  YEARS ENDED MARCH 31, 1995 AND 1996
 
    REVENUES.   The Company's  revenues increased by 70.2%  from $4.0 million in
fiscal 1995 to $6.9 million in fiscal 1996. Domestic revenues increased by 72.2%
from $3.2  million  in  fiscal  1995  to  $5.6  million  in  fiscal  1996  while
international  revenues increased by 62.2% from  $817,000 in fiscal 1995 to $1.3
million in fiscal 1996. The increase in revenues reflected increased unit  sales
of   the  L-D-X  Analyzer   and  test  cassettes   to  hospitals,  managed  care
organizations, public  health departments,  corporations and  other health  care
providers  in the  screening market. The  Company's product sales  to the United
States monitoring market were minimal in  each fiscal year. The Company  expects
that  international revenues will  continue to decline as  a percentage of total
revenues in future periods as the Company increases sales and marketing  efforts
in the monitoring market in the United States.
 
    COSTS  OF PRODUCTS SOLD.   Costs of products sold  increased 14.5% from $3.9
million in fiscal  1995 to $4.5  million in fiscal  1996, as unit  sales of  the
L-D-X  Analyzer and test cassettes increased. Gross margin was 2.6% and 34.5% in
fiscal 1995 and  1996, respectively.  The improvement  in the  gross margin  was
primarily  attributable  to  improved  cassette  manufacturing  yields, improved
quality assurance procedures  and growth  in the  volume of  units sold.  During
fiscal  1995,  the Company  improved cassette  manufacturing yields  and quality
assurance procedures and  reduced staffing levels  by eliminating technical  and
engineering  positions specific to  initial product development  and scale-up of
manufacturing  capacity.  The  resulting  manufacturing  efficiencies  and  cost
reductions were reflected for the full year of fiscal 1996.

    The Company has obtained rights to use certain technology in the manufacture
of  certain of its products.  The related agreements provide  for the Company to
pay royalties ranging from 0.6% to 6.0% of net sales of the applicable products.
Total royalty  expense for  fiscal  1995 and  1996  was $132,000  and  $381,000,
respectively, and was charged to costs of products sold.
 
    RESEARCH  AND  DEVELOPMENT.    Research  and  development  expenses remained
constant between  fiscal 1995  and fiscal  1996  as a  result of  the  Company's
decision  to concentrate available resources on expansion of sales and marketing
activities for  existing test  panels. However,  the Company  believes that  its
future  revenue growth and profitability will  depend, in part, upon its ability
to complete development and successfully  introduce new test panels designed  to
extend the L-D-X System's capabilities to include additional tests useful in the
screening and monitoring markets. The Company is currently developing additional
tests  to detect disease  states such as metabolic  bone diseases and disorders,
prostate cancer and diabetes. Each  of these new tests is  at an early stage  of
development  and the  Company will be  required to undertake  time consuming and
costly development activities and seek regulatory approval for these new  tests.
As  a result,  the Company currently  anticipates that  research and development
expenditures  will  increase   significantly  in  future   periods  as   product
development and manufacturing scale-up efforts for new tests increase.
 
    SALES AND MARKETING.  Sales and marketing expenses increased 17.6% from $2.7
million in fiscal 1995 to $3.2 million in fiscal 1996. The increase in sales and
marketing  expenses  was primarily  attributable to  expansion of  the Company's
domestic  direct  sales  and   marketing  organization,  increased   commissions
associated  with increased product sales and,  to a lesser extent, participation
in domestic conferences and trade shows. The Company currently anticipates  that
sales  and marketing  expenses will  increase in  future periods  as the Company
expands sales  and marketing  activities to  address the  monitoring market,  in
particular the POL segment of the monitoring market.
 
    GENERAL  AND ADMINISTRATIVE.  General  and administrative expenses decreased
30.6% from $2.0  million in  fiscal 1995  to $1.4  million in  fiscal 1996.  The
decrease  in  general  and administrative  expenses  was primarily  a  result of
reduced headcount and  reduced expenditures  for rent and  insurance. In  fiscal
1995,  general  and  administrative  expenses  included  a  one-time  charge  of
approximately $114,000 as a result of headcount reductions. Absent such one-time
charge, general and administrative expenses for fiscal 1995 would have been $1.9
million.
 
    INTEREST INCOME (EXPENSE), NET.  Interest income was earned on investment of
cash balances generated from  prior equity financings  of the Company.  Interest
expense  was incurred on capital  lease financings, the bank  line of credit and
long-term debt obtained by the Company.
 
  YEARS ENDED MARCH 31, 1994 AND 1995
 
    REVENUES.  Revenues increased 33.3% from $3.0 million in fiscal 1994 to $4.0
million in fiscal  year 1995.  Domestic revenues  increased by  74.6% from  $1.8
million  in  fiscal 1994  to $3.2  million in  fiscal 1995,  while international
revenues decreased by  31.1% from  $1.2 million in  fiscal 1994  to $817,000  in
fiscal 1995. The increase in domestic revenues reflected an increase in sales of
diagnostic tests to the domestic screening market. The decrease in international
revenues  reflected the completion  in fiscal 1994  of the Company's promotional
activities with  Warner Lambert/Parke  Davis Corporation  ("Warner Lambert")  in
Italy relating to Warner Lambert's hypolipidemic agent, Lopid.
 
    COSTS  OF PRODUCTS SOLD.   Costs of products sold  decreased 20.9% from $5.0
million in fiscal 1994 to $3.9 million in fiscal 1995. Costs of products sold as
a percentage of total revenues decreased from 164.1% in fiscal 1994 to 97.4%  in
fiscal 1995. The decrease was primarily attributable to the Company's successful
completion  of  efforts to  improve  cassette manufacturing  yields  and improve
quality assurance  procedures. The  improvements in  cassette manufacturing  and
quality  assurance procedures enabled  the Company to  reduce staffing levels by
eliminating technical  and engineering  positions  specific to  initial  product
development and expansion of the Company's manufacturing capacity. Total royalty
expense for fiscal 1994 was $140,000 and was charged to costs of products sold.
 
                                       25
<PAGE>
    RESEARCH AND DEVELOPMENT.  Research and development expenses decreased 66.5%
from  $2.1 million in  fiscal 1994 to  $715,000 in fiscal  1995. The decrease in
research and  development expenses  was  primarily a  result of  completing  the
development  of, and obtaining  FDA approval for,  a TC/HDL/ Glucose  test and a
Lipid Profile  plus Glucose  test  and, transitioning  to product  marketing  in
fiscal  1995 from product  development in fiscal 1994.  The fiscal 1995 expenses
included $715,000 for new product  development and product enhancements to  meet
customer  demands while fiscal 1994 expenses included $733,000 for manufacturing
scale-up costs and $1.4  million related to continued  development of the  L-D-X
System and its related products.
 
    SALES  AND MARKETING.  Sales and marketing expenses decreased 7.4% from $2.9
million in fiscal 1994 to $2.7 million in fiscal 1995. The decrease in sales and
marketing expenses  was a  direct result  of the  Company's efforts  to  improve
efficiency.  During  fiscal 1995,  the  Company focused  on  increasing domestic
product sales  while selectively  targeting potential  sources of  international
product  sales. The strategy  allowed the Company to  reduce sales and marketing
expenses in fiscal 1995 although product sales increased.
 
    GENERAL AND ADMINISTRATIVE  EXPENSES.  General  and administrative  expenses
decreased 13.3% from $2.3 million in fiscal 1994 to $2.0 million in fiscal 1995.
General  and administrative expenses for fiscal  1995 included a one-time charge
of approximately $114,000  due to a  reduction in the  number of  administrative
personnel.  Absent such one-time charge, general and administrative expenses for
fiscal 1995  would  have been  $1,886,000.  In addition,  fiscal  1994  expenses
included  a net gain of $290,000 upon  the settlement of a dispute in connection
with a licensing  agreement. Absent  such net gain,  general and  administrative
expenses  for fiscal 1994  would have been $2.6  million. After consideration of
the net gain and one-time charge, actual general and administrative expenses for
fiscal 1995  decreased  approximately $704,000  or  27% from  fiscal  1994.  The
decrease  resulted  from the  Company's efforts  to  control costs  and conserve
resources through reduced headcount and improved operating efficiency.
 
    INTEREST INCOME (EXPENSE), NET.  Interest income was earned on investment of
cash balances generated from equity financings of the Company. Interest  expense
was incurred on capital lease financings obtained by the Company.
 
  INCOME TAX CARRYFORWARDS
 
    As  of  March 31,  1996, the  Company had  net operating  loss carryforwards
available to reduce taxable income through 2011 for federal and state income tax
purposes  of  approximately  $46.0  million  and  $21.0  million,  respectively.
Additionally,  the  Company had  research  and development  credit carryforwards
available to reduce income taxes through  2011 for federal and state income  tax
purposes  of approximately $1.5 million and  $493,000, respectively. There is an
annual limitation of approximately $1.5 million for federal and state income tax
reporting purposes on the use of approximately $8.1 million and $1.1 million  of
net  operating losses, and of $390,000 and $160,000 of tax credit carryforwards,
respectively. The Company's  net operating losses  and tax credit  carryforwards
incurred  prior  to  December  1992  are  subject  to  an  annual  limitation of
approximately $5.5 million for federal  and state income tax reporting  purposes
on the use of approximately $28.2 million and $8.1 million of net operating loss
carryforwards,  respectively, and  of $1.2  million and  $379,000 of  tax credit
carryforwards, respectively. If the amount of these limitations are not utilized
in any  year, the  amount not  utilized  increases the  allowable limit  in  the
subsequent year.
 
  IMPACT OF ADOPTION OF NEW ACCOUNTING STANDARDS
 
    In  March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting  Standards  No.  121  "Accounting  for  the  Impairment  of
Long-Lived  Assets and  for Long-Lived  Assets to  Be Disposed  Of," ("FAS 121")
which requires the Company to  review for impairment long-lived assets,  certain
identifiable intangibles and goodwill related to those assets whenever events or
changes in circumstances indicate that the carrying amount of an asset might not
be recoverable. In
 
                                       26
<PAGE>
certain  situations, an  impairment loss would  be recognized.  The Company will
adopt FAS 121 during fiscal 1997 and, based on its initial evaluation, does  not
expect  its  adoption  to have  a  material  impact on  the  Company's financial
condition or results of operations.
 
    In October 1995, the Financial  Accounting Standards Board issued  Statement
of   Financial  Accounting   Standards  No.  123   "Accounting  for  Stock-Based
Compensation" ("FAS  123")  which  established  a fair  value  based  method  of
accounting   for   stock-based  compensation   plans  and   requires  additional
disclosures for  those  companies who  elect  not to  adopt  the new  method  of
accounting.  The  Company will  adopt FAS  123 during  fiscal 1997.  The Company
intends to continue to  account for employee stock  options using the  intrinsic
value method prescribed by APB Opinion No. 25 and to adopt the "disclosure only"
pro forma alternative described in FAS 123.
 
  POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS
 
    The  Company may experience significant fluctuations in revenues and results
of operations on a quarter to  quarter basis in the future. Quarterly  operating
results  will fluctuate due to numerous  factors, including the timing and level
of market acceptance of the L-D-X System, particularly with respect to POLs, the
timing of introduction and  availability of new tests,  the timing and level  of
expenditures  associated with new product development activities, the timing and
level of expenditure associated with expansion of sales and marketing activities
and  overall  operations,  the  Company's  ability  to  cost-effectively  expand
cassette  manufacturing capacity and maintain  consistently acceptable yields in
the  manufacture  of  cassettes,  the  timing  of  establishment  of   strategic
distribution  arrangements and  success of  the activities  conducted under such
arrangements, variations in  manufacturing efficiencies, changes  in demand  for
its products based on changes in third party reimbursement, 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 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   and  order
cancellations 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  actual
revenues  do not meet expectations,  the Company's business, financial condition
and results of operations could be materially adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has financed its operations primarily through the sale of equity
securities and, to a lesser extent, through capital lease financings and a  long
term   note  payable.  Through   March  31,  1996,   the  Company  had  received
approximately $55.1 million in net proceeds from equity financings. As of  March
31,  1996, the Company had approximately  $361,000 of cash and cash equivalents.
In addition, the Company had  $3.75 million of restricted marketable  securities
that  currently secure a $3.0  million revolving bank line  of credit. While the
line of credit is in effect, the Company is required to maintain on deposit with
the bank $3.75  million of restricted  marketable securities or  a $3.0  million
certificate  of deposit  as pledged  collateral, restricted  as to  use when the
Company has  outstanding borrowings  under  the agreement.  The line  of  credit
expires  on October 31, 1996. As of March 31, 1996, borrowings under the line of
credit totaled  $250,000.  If  the  Company's  cash  and  restricted  marketable
securities  were to fall  below $3.0 million,  the Company would  be required to
either renegotiate the terms  or cancel the revolving  line of credit. At  March
31,  1996, the Company  also had approximately $1.3  million outstanding under a
long term note. The note contains various provisions including requirements that
the Company maintain  at least $3.0  million in cash  and restricted  marketable
securities  and a  security deposit  in the  amount of  $150,000 payable  to the
lender in  the event  of  a default  on  the note.  If  the Company's  cash  and
restricted  marketable securities were  to fall below  $3.0 million, the Company
would be  required  to deposit  with  the lender  an  additional $200,000  as  a
security deposit.
 
                                       27
<PAGE>
    Net  cash used in operating activities  was approximately $7.2 million, $5.0
million and $2.4 million in fiscal 1994, 1995 and 1996, respectively. Cash  used
in  operating activities during  fiscal 1996 resulted  primarily from net losses
and the net effect of increases  in inventory, receivables and accounts  payable
and  accrued expenses  of $559,000,  $443,000 and  $721,000, respectively, which
reflects the effect of increased revenues  from fiscal 1995 and the  anticipated
increase  in  revenues  during  fiscal  1997.  Net  cash  provided  by investing
activities in  fiscal  1995 resulted  primarily  from the  sales  of  marketable
securities.  During fiscal 1996, net cash used in investing activities reflected
the Company's purchases of  property and equipment. Net  cash used in  financing
activities  in fiscal 1995 reflected the repayment of capital lease obligations,
while the net  cash provided by  financing activities in  fiscal 1996  reflected
approximately  $1.7 million in net proceeds from a note payable, borrowing under
the line of credit and issuances of Common Stock.
 
    The Company intends  to expend  substantial funds for  product research  and
development,   expansion  of  sales  and   marketing  activities,  expansion  of
manufacturing capacity and other working capital and general corporate purposes.
Although the Company  believes that  the net proceeds  of a  public offering  of
Common  Stock currently expected to be completed in June 1996, together with its
unrestricted cash balances,  internally generated funds,  bank borrowings  under
existing  lines of credit and  proceeds from issuances of  Common Stock to Metra
Biosystems  will  be  sufficient  to  meet  its  capital  requirements  for  the
foreseeable  future, there can be no assurance that the Company will not require
additional financing. The  Company's actual liquidity  and capital  requirements
will  depend upon numerous additional factors, including the costs and timing of
expansion of  manufacturing capacity,  the  number and  type  of new  tests  the
Company  seeks  to develop,  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
and enforcing 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 raise additional  funds through  public or  private financing,  collaborative
relationships  or  other arrangements.  Any additional  equity financing  may be
dilutive  to  shareholders,  and  debt  financing,  if  available,  may  involve
restrictive   covenants.  Collaborative  arrangements,  if  necessary  to  raise
additional funds, may require the Company to relinquish its rights to certain of
its technologies, products or marketing territories. The failure of the  Company
to  raise  capital when  needed  could have  a  material adverse  effect  on the
Company's business, financial condition and results of operations. There can  be
no assurance that such financing, if required, will be available on satisfactory
terms, if at all.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
Shareholders of Cholestech Corporation
 
In  our opinion,  the financial statements  listed in the  index appearing under
Item 14(a)(1) and (2) on page 24  present fairly, in all material respects,  the
financial  position of  Cholestech Corporation at  March 31, 1995  and March 29,
1996, and the results of its operations and its cash flows for each of the three
years in the period ended March 29, 1996, in conformity with generally  accepted
accounting  principles. These financial statements are the responsibility of the
Company's management;  our responsibility  is  to express  an opinion  on  these
financial  statements  based on  our audits.  We conducted  our audits  of these
statements in  accordance  with  generally  accepted  auditing  standards  which
require  that we plan and perform the audit to obtain reasonable assurance about
whether the financial  statements are  free of material  misstatement. An  audit
includes  examining,  on  a  test basis,  evidence  supporting  the  amounts and
disclosures in  the financial  statements, assessing  the accounting  principles
used  and significant estimates  made by management,  and evaluating the overall
financial  statement  presentation.  We  believe  that  our  audits  provide   a
reasonable basis for the opinion expressed above.

1.  OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
OPERATIONS
 
    Cholestech  Corporation (the "Company") was incorporated February 2, 1988 to
develop, manufacture and  sell point-of-care systems  which can perform  various
diagnostic tests using a single drop of whole blood.
 
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
FISCAL YEAR END
 
    The  Company's fiscal year is a 52-53  week period ending on the last Friday
in March. Fiscal  1994, 1995  and 1996  comprised 52,  53 and  52 week  periods,
respectively.
 
REVENUE RECOGNITION
 
    All  revenues from  product sales  are recognized  at the  time products are
shipped and are denominated in U.S. dollars. The Company also provides an amount
for estimated sales returns.
 
CASH AND CASH EQUIVALENTS AND MARKETABLE SECURITIES
 
    The Company considers all highly liquid investments with a maturity of three
months or less at the date of purchase to be cash equivalents; investments  with
maturities  between  three  and  twelve  months  are  classified  as  short-term
marketable securities and investments with maturities which exceed twelve months
are classified as long-term marketable  securities. The Company has  established
policies  which limit  the type,  credit quality and  length of  maturity of the
securities in  which  it invests.  The  Company's investment  policy  allows  no
investments   in  any  single  private  issuer  to  exceed  $1,000,000  and  the
investments must have, at a minimum, a credit rating of AA. Cash equivalents and
restricted marketable  securities  at  March 29,  1996  consist  principally  of
investments  in money-market funds, commercial  paper and U.S. government-agency
obligations and  are classified  as available  for sale.  Restricted  marketable
securities  are carried at amortized cost, which approximates market. Unrealized
gains and losses are immaterial.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments which potentially expose the Company to concentrations
of credit risk include trade accounts receivable; however, this risk is  limited
due  to the  large number of  individually smaller customers.  Collateral is not
required on these  transactions. The  Company maintains  reserves for  potential
credit  losses and such  losses, in the aggregate,  have not exceeded management
expectations.
 
INVENTORIES
 
    Inventories are stated at the lower of cost or market, cost being determined
using the first-in,  first-out (FIFO)  method. Cost  includes direct  materials,
direct labor and manufacturing overhead.
 
PROPERTY AND EQUIPMENT
 
    Property  and equipment are  stated at cost.  Depreciation is computed using
the straight-line method over the estimated  useful lives of the related  assets
which  range from two  to five years. Leasehold  improvements are amortized over
their estimated useful lives, not to exceed  the term of the related lease.  The
cost  of additions and improvements is capitalized while maintenance and repairs
are charged to expense as incurred.
 
WARRANTIES
 
    The Company's  products  are generally  under  warranty against  defects  in
material  and workmanship  for a  period of  one year.  The Company  accrues for
estimated future warranty costs at the time of sale.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    The Company uses  the asset and  liability method of  accounting for  income
taxes, which requires the recognition of deferred tax liabilities and assets for
the  expected  future  tax  consequences of  temporary  differences  between the
financial reporting and income tax bases of assets and liabilities.
 
NET LOSS PER SHARE
 
    Net loss per  share is computed  by dividing  the net loss  by the  weighted
average  number of common  and common equivalent  shares outstanding during each
period. Common equivalent shares are included in determining net loss per share,
to the extent they are dilutive, using the treasury stock method.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying  value  of cash  equivalents,  short-term bank  borrowings  and
current  portion  of long-term  debt  approximate fair  value  due to  the short
maturity of those instruments.
 
    The fair  value of  the  Company's long-term  debt, which  approximates  its
carrying  value, is estimated based on the  quoted market prices for the same or
similar issues  or on  the current  rates offered  to the  Company for  debt  of
similar maturities.
 
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  reported amounts  of  assets and  liabilities and
disclosure of contingent  assets and liabilities  at the date  of the  financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
IMPACT OF ADOPTION OF NEW ACCOUNTING STANDARDS
 
    In  March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting  Standards  No.  121  "Accounting  for  the  Impairment  of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("FAS 121") which
requires  the Company  to review  for impairment  of long-lived  assets, certain
identifiable intangibles and goodwill related to those assets whenever events or
changes in circumstances indicate that the carrying amount of an asset might not
be recoverable. In certain situations,  an impairment loss would be  recognized.
The  Company will  adopt FAS 121  during fiscal  1997 and, based  on its initial
evaluation, does  not expect  its adoption  to  have a  material impact  on  the
Company's financial condition or results of operations.
 
    In  October 1995, the Financial  Accounting Standards Board issued Statement
of  Financial  Accounting   Standards  No.  123   "Accounting  for   Stock-Based
Compensation"  ("FAS  123")  which  established a  fair  value  based  method of
accounting  for   stock-based  compensation   plans  and   requires   additional
disclosures  for  those companies  who  elect not  to  adopt the  new  method of
accounting. The  Company will  adopt FAS  123 during  fiscal 1997.  The  Company
intends  to continue to  account for employee stock  options using the intrinsic
value method prescribed by APB Opinion No. 25 and to adopt the "disclosure only"
pro forma alternative described in FAS 123.

6.  COMMITMENTS
    The Company has obtained rights to use certain technology in the manufacture
of certain of its  products. The related agreements  provide for the Company  to
pay  royalties ranging from 0.6% to 6%  of net sales of the applicable products.
Total royalty expense for fiscal 1994, 1995 and 1996 was $140,000, $132,000  and
$381,000, respectively.
 
7.  SHAREHOLDERS' EQUITY
PREFERRED STOCK
 
    The  Company  is  authorized  to  issue  5,000,000  shares  of  undesignated
Preferred Stock. The Board of Directors has the authority to issue the Preferred
Stock in  one  or  more  series  and to  fix  the  price,  rights,  preferences,
privileges  and restrictions thereof, including dividend rights, dividend rates,
conversion rights,  voting  rights,  terms  of  redemption,  redemption  prices,
liquidation  preferences and the  number of shares constituting  a series or the
designation of such series, without any further vote or action by the  Company's
shareholders.
 
WARRANTS
 
    At  March 29, 1996,  there were warrants  for 39,242 shares  of Common Stock
outstanding at an exercise price  of $3.50 per share,  which expire on July  15,
1999.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    In  April 1992,  the Company adopted  the Employee Stock  Purchase Plan (the
"Plan") which reserved 75,000 shares of Common Stock to be issued in  accordance
with  the Internal Revenue Code under such  terms as approved by the officers of
the Company. In fiscal 1996, 32,177  shares and 18,637 shares were purchased  by
employees  at prices of $1.59 and $2.01 per share, respectively. In August 1995,
the shareholders  approved an  increase in  the number  of shares  reserved  for
issuance  under the Plan  from 75,000 to  200,000. The price  of stock purchased
under the Purchase Plan is 85% of the lower of (i) the fair market value of  the
Common  Stock at the  beginning of the  offering period or  (ii) the fair market
value of the Common Stock at the  end of the offering period. Employees may  end
their  participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with the Company.
 
STOCK INCENTIVE PROGRAM
 
    The Board  of  Directors  adopted  the 1988  Stock  Incentive  Program  (the
"Program")  which provides that incentive  stock options (ISOs) and nonqualified
stock options (NSOs) for shares of Common Stock may be granted to employees  and
consultants  of the Company. In accordance with the Program, the stated exercise
price shall not be  less than 100% and  85% of the fair  market value of  Common
Stock on the date of grant for ISOs and NSOs, respectively. The Program provides
that the options shall be exercisable over a period not to exceed five years and
a day and shall vest at a rate of at least 25 percent each year over a four year
period.  Vesting may  be accelerated  upon the  occurrence of  certain events as
described in  the  stock option  agreement.  In August  1995,  the  shareholders
approved  an  increase in  the number  of  shares of  Common Stock  reserved for
issuance under the Program from 1,300,000 to 1,550,000.
 
    As a result of the Company's initial public offering of Common Stock in June
1992, options issued in November 1991 were determined to have been issued at  an
amount less than the fair market value of the Company's Common Stock at the date
the  options were granted. The difference between  the option price and the fair
market value  of  the  Company's  Common  Stock  was  determined  to  contain  a
compensatory   element.  The  compensatory  element  resulted  in  a  charge  to
operations in  fiscal 1994,  1995 and  1996 of  $104,000, $72,000  and  $39,000,
respectively.

7.  SHAREHOLDERS' EQUITY (CONTINUED)
    In  August 1994, the Company's  Board of Directors approved  a plan to offer
all current employees  and consultants holding  outstanding options to  purchase
Common  Stock of the Company  with exercise prices in  excess of $3.50 per share
the opportunity to exchange such options for options priced at $3.50 per  share.
In  exchange  for  the  new options,  the  employees  and  consultants forfeited
approximately 25 percent of their vesting  credit. At the time of the  approval,
the fair market value of the Company's Common Stock was $2.50 per share.
 
    Stock option activity under the Program is as follows:
