                               PROSPECTUS SUMMARY
 
  This Prospectus contains certain statements of a forward-looking nature
relating to future events or the future financial performance of the Company.
Prospective investors are cautioned that such statements are only predictions
and that actual events or results may differ materially. In evaluating such
statements, prospective investors should specifically consider the various
factors identified in this Prospectus, including the matters set forth under
the caption "Risk Factors," which would cause actual results to differ
materially from those indicated by such forward-looking statements. The
following summary is qualified in its entirety by the more detailed
information, including the Consolidated Financial Statements and Notes thereto,
appearing elsewhere in this Prospectus.
 
                                  THE COMPANY
   
  Applied Imaging designs, develops, manufactures and markets automated
clinical analysis systems used by laboratories for prenatal and other genetic
testing. The Company's cytogenetic instrumentation business, which has sold
systems to approximately 500 sites in more than 30 countries since its
inception, includes systems that enable laboratories to automate aspects of the
detection of chromosomal abnormalities associated with conditions such as
Down's Syndrome. In addition to the Company's core instrument business, the
Company is developing a proprietary genetic screening system designed to enable
prenatal screening for genetic abnormalities by isolating fetal red blood cells
("fetal blood cells") from a routine maternal blood sample. This new system is
designed to improve current prenatal screening techniques by providing an
accurate, timely and cost-effective procedure without the risks of miscarriage
or fetal damage associated with invasive prenatal testing.     
   
  Prenatal genetic testing is currently performed either invasively by
extracting, culturing and analyzing fetal cells taken from amniotic fluid or
placental tissue, or non-invasively by analysis of serum markers derived from a
maternal blood sample. The Company estimates approximately 2.3 million pregnant
women in the United States undergo some form of prenatal screening each year.
Despite the widespread use of prenatal screening, there are significant
shortcomings associated with existing screening methods. Invasive procedures,
which include amniocentesis (extracting fetal cells from the amniotic sac) and
chorionic villus sampling (extracting tissues from the placenta), involve
direct extraction of fetal cells. These procedures can accurately detect a
broad range of chromosomal disorders but pose a risk of fetal loss of between
0.5-1%. Due to this risk, these invasive procedures are usually only
recommended for women age 35 or older, at which ages, the risk of having a
child with a chromosomal disorder is greater than the risk of spontaneous
miscarriage associated with these procedures. The Company estimates that these
procedures are performed on approximately 300,000 women annually in the United
States. The non-invasive screening procedures, which include alpha-fetoprotein
("AFP") and the "triple test," both of which are blood chemistry tests, are
currently broadly used for pregnant women including those under the age of 35
with approximately 2 million tests performed annually in the United States.
While these tests present no risk to the fetus since they do not directly
analyze fetal cells, they are much less accurate with detection rates of
approximately 60% for chromosomal disorders and false positive rates of
approximately 5%.     
   
  The Company's prenatal screening system under development is intended to
provide an accurate, non-invasive test by directly analyzing fetal blood cells
isolated from a routine maternal blood sample. The Company's proprietary
screening system incorporates (i) a patented blood-based procedure to enrich
the concentration of fetal blood cells, (ii) automated image analysis
instrumentation to identify the fetal blood cells and (iii) the use of third-
party DNA probes to identify certain chromosomal disorders present in fetal
blood cells. This system is expected to be accurate because it evaluates actual
fetal cells while posing no risk to the fetus. The Company's prenatal screening
system is currently in preclinical evaluation and application for FDA approval
has not yet been submitted.     
 
                                       3
<PAGE>
 
   
  The Company believes that a key aspect of its prenatal screening system is
its ability to enrich and identify fetal blood cells so that they can be
directly analyzed using available DNA probe technology. As of August 1996, the
Company and its collaborators have used the fetal blood cell enrichment
procedure on a total of 133 maternal blood samples. The Company's system has
achieved fetal blood cell identification in 120 of the 133 samples tested, or
90% of cases. In 13 maternal blood samples (10% of the total samples), no fetal
blood cells were found. The Company intends to continue preclinical and
clinical evaluation of this system and anticipates beginning a multi-site
international clinical trial during the first half of 1997. Additionally, the
Company intends to file two separate 510(k) applications for the fetal cell
enrichment and automated imaging system components of its system before the end
of 1996, and an additional application (either a 510(k), tier III or a PMA) for
the DNA-probe component of its prenatal screening system. There can be no
assurance that the Company will be successful in establishing its prenatal
screening system as a broad-based prenatal screening procedure nor can there be
any assurance that the prenatal screening system will be approved for marketing
by the FDA or, if approved, that clinical acceptance will be achieved.     
   
  The Company's strategy is to establish its system as a broad-based prenatal
screening procedure. The Company anticipates that sales of this system, if
approved by the FDA, will include both its proprietary consumable enrichment
kits, used to separate fetal blood cells from maternal blood samples and
imaging instrumentation used to analyze the cells. These new image analysis
systems are contemplated to be compatible with the Company's existing installed
cytogenetic instrument base. The Company believes that it can leverage its
existing infrastructure, worldwide distribution capabilities and extensive
laboratory relationships to support the world-wide introduction of this fetal
cell screening system under development. Furthermore, the Company believes that
its new cell enrichment and image analysis system could have clinical utility
for cancer applications and the prenatal diagnosis of single gene disorders,
and it intends to pursue the development of these other potential applications.
Significant additional research and development will be necessary to establish
the clinical utility of the Company's cell enrichment techniques and image
analysis system for these other potential applications.

                                 RISK FACTORS
   
  This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth in the following risk factors and elsewhere
in this Prospectus. The following principal factors should be carefully
considered in evaluating the Company and its business before purchasing the
Common Stock offered hereby.     
 
PRENATAL SCREENING SYSTEM IN EARLY STAGE OF DEVELOPMENT; NO ASSURANCE OF
SUCCESSFUL DEVELOPMENT OR COMMERCIALIZATION
   
  The Company's prenatal screening system is in an early stage of development
and testing, and application for FDA approval has not yet been submitted. To
date, the Company's technology for enriching the concentration of nucleated
fetal red blood cells in maternal blood samples has been subjected only to
preclinical testing by the Company. The isolation, enrichment and analysis of
fetal cells from a maternal blood sample is difficult and poses a significant
technical challenge due to their rarity in maternal blood. Estimates of the
frequency of fetal cells in maternal blood generally range from 1 in 1 million
to 1 in 10 billion. Preclinical testing of the Company's prenatal screening
system has only recently shown progress in fetal cell isolation and detection.
As of August 1996, the Company and its collaborators have used the fetal blood
cell enrichment procedure on a total of 133 maternal blood samples. In these
studies, the Company's system achieved fetal cell identification in 120 of the
133 samples tested. In 13 of these 133 samples, no fetal blood cells were
found. In seven of the 120 samples in which fetal cell identification was
achieved, the Company's investigators identified and counted only one fetal
cell. The Company has not yet determined how many fetal cells, if any, can be
obtained using its process and whether its results can be duplicated in larger
studies. There can be no assurance that the Company's prenatal screening
system will be able to detect fetal cells in amounts sufficient to allow for
the detection and analysis of chromosomal abnormalities. In addition, the
Company's preclinical testing in analyzing cells has almost exclusively been
limited to detecting male and female chromosomes and has not yet focused on
chromosomal abnormalities such as Down's Syndrome. There can be no assurance
that the Company's prenatal screening system will be able to effectively and
accurately detect Down's Syndrome or other chromosomal abnormalities. The
development and potential commercialization of the Company's prenatal
screening system will require significant research and development,
substantial investment and clinical testing and regulatory clearances or
approvals. The Company plans to continue to conduct preclinical testing in
order to analyze the feasibility of its prenatal screening system. Such
efforts may disclose significant technical obstacles that need to be overcome
prior to pursuing clinical trials and seeking necessary regulatory approvals.
For example, during preclinical testing the Company discovered that the gel in
the preformed density gradients portion of its prenatal screening system
destabilized if not properly stored at cool temperatures and, in any event,
destabilized within two weeks even if properly stored. Although the Company
believes it has identified a modified gel with greater stability and longer
shelf life, there can be no assurance that this instability will be resolved
or that other problems will not be detected. Such problems could have the
effect of delaying or preventing the successful development of the Company's
prenatal screening system. There can be no assurance that the Company will be
able to develop this technology into a reliable and effective prenatal
screening system, that required regulatory clearances or approvals for
commercialization of its system will be obtained in a timely manner, or at
all, or that the Company's prenatal screening system or other products under
development, if introduced commercially, will be successful. If the Company is
unable to successfully develop and market its prenatal screening system, the
Company's business, financial condition and results of operations would be
materially and adversely affected. See "Business--Applied Imaging's Prenatal
Screening System."     
 
LACK OF CLINICAL DATA
 
  The Company has conducted no clinical trials of its prenatal screening
system pursuant to FDA reviewed or FDA approved protocols. There can be no
assurance that the Company will commence such clinical testing, or once
commenced, that such testing can be completed successfully within the
Company's expected time frame and budget, if at all, or that the Company's
products will prove to be reliable and effective in clinical trials. If
clinical trials are initiated, such trials may disclose significant technical
obstacles having the effect of delaying
 
                                       6
<PAGE>
 
or preventing the development, testing, regulatory approval and
commercialization of the Company's prenatal screening system. There can be no
assurance that the results of such clinical trials will be consistent with the
Company's limited preclinical results to date or would be sufficient to obtain
regulatory clearance or approval or clinical acceptance. If the Company is
unable to initiate and conclude successfully clinical trials of its prenatal
screening system, the Company's business, financial condition and results of
operations would be materially and adversely affected.
 
NO ASSURANCE OF CLINICAL ACCEPTANCE
 
  The isolation of fetal cells from maternal blood is a new and novel
development. The clinical acceptance of the Company's prenatal screening
system will depend upon its acceptance by the medical community and third-
party payors as clinically useful, reliable, accurate, and cost-effective
compared to existing and future procedures. Clinical acceptance will depend on
numerous factors, including the establishment of the system's ability to
isolate sufficient numbers of fetal cells during the early stages of
pregnancy, to adequately enrich the concentration of nucleated fetal cells,
and to reliably analyze and detect the presence of chromosomal abnormalities.
Clinical acceptance will also depend on the receipt of regulatory clearances
in the United States and internationally, the availability of third-party
reimbursement and the Company's ability to adequately train laboratory
technicians and cytogeneticists on how to use the prenatal screening system.
In addition, there can be no assurance that the Company's prenatal screening
system will be a preferable alternative to existing procedures such as
maternal AFP or triple test which detect neural tube defects in addition to
chromosomal abnormalities, or that the prenatal screening system will not be
rendered obsolete or noncompetitive by products under development by other
companies. The Company's system is intended to initially screen for Down's
Syndrome and may not compete favorably with widely accepted methodologies such
as amniocentesis or CVS that are highly accurate and diagnose a broader range
of abnormalities from one sample of fetal cells. Patient acceptance of the
Company's prenatal testing system will depend in part upon physician
recommendations as well as other factors, including the effectiveness and
reliability of the procedure as compared to amniocentesis, CVS and serum
marker procedures. Even if the Company's prenatal screening system is
clinically adopted, physicians may elect not to recommend the procedure unless
acceptable reimbursement from health care payors is available. There can be no
assurance that the Company's prenatal screening system under development will
be accepted by the medical community or that market demand for such system
will be sufficient to allow the Company to achieve profitable operations.
Failure of the Company's prenatal screening procedure, for whatever reason, to
achieve significant clinical adoption or failure of the Company's system to
achieve any significant market acceptance would have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business--Applied Imaging's Prenatal Screening System."
 
ACCUMULATED DEFICIT; FUTURE LOSSES
   
  From its inception in July 1986 through June 30, 1996, the Company has
generated an accumulated deficit of approximately $10.4 million. The Company
expects its operating losses to continue to increase as it continues its
efforts to develop and test its prenatal screening system. There can be no
assurance that its prenatal screening system under development will be
commercially marketed or, if commercially marketed, that the Company will ever
receive sufficient revenue to achieve profitability and failure to do so would
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."     
 
QUARTERLY FLUCTUATIONS
 
  The Company has experienced and expects to continue to experience
significant fluctuations in its quarterly operating results. Factors which may
have an influence on the Company's operating results in a particular quarter
include (i) demand for the Company's products, new product introductions by
the Company or its competitors or transitions to new products; (ii) the
results of preclinical or planned clinical trials and, if ever received, the
timing
 
                                       7
<PAGE>
 
of regulatory and third-party reimbursement approvals; (iii) the timing of
orders and shipments; (iv) the mix of sales between distributors and the
Company's direct sales force; (iv) competition, including pricing pressures;
(v) the timing and amount of research and development expenses, including
clinical trial-related expenditures; (vi) seasonal factors; (vii) foreign
currency fluctuation; and (viii) the delay between incurrence of expenses to
develop new products, including related marketing and service capabilities,
and realization of benefits from such efforts. The Company typically has
experienced increased sales in its first and fourth quarter. The Company
believes this pattern of fluctuating revenues reflects the budgetary spending
practices of the Company's customer base which consists primarily of public
and private cytogenetic laboratories, research organizations and hospitals
operating on annual budgets. There can be no assurance that this trend will
continue. Due to all the foregoing factors, it is likely that in some future
quarter the Company's operating results will be below the expectations of
public market analysts and investors. In such event, the price of the
Company's Common Stock would likely be materially adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Results of Operations" and "Business--Manufacturing."
 
ADDITIONAL CAPITAL REQUIREMENTS; NO ASSURANCE FUTURE CAPITAL WILL BE AVAILABLE
   
  The Company has expended and will continue to expend substantial funds for
research and development, preclinical testing, planned clinical
investigations, capital expenditures, and manufacturing and marketing of its
products. The timing and amount of spending of such capital resources cannot
be accurately determined at this time and will depend upon several factors,
including the progress of its research and development efforts and planned
clinical investigations, competing technological and market developments,
commercialization of products currently under development, and market
acceptance and demand for the Company's products. To the extent required, the
Company may seek to obtain additional funds through equity or debt financing,
collaborative or other arrangements with other companies and from other
sources. If additional funds are raised by issuing equity securities, further
dilution to stockholders could occur. There can be no assurance that
additional financing will be available when needed or on terms acceptable to
the Company. If adequate funds are not available, the Company could be
required to delay development or commercialization of certain of its products,
to license to third parties the rights to commercialize certain products or
technologies that the Company would otherwise seek to commercialize for
itself, or to reduce the marketing, customer support or other resources
devoted to certain of its products each of which could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Use of Proceeds," "Dilution" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."     
   
DEPENDENCE ON PRENATAL SCREENING SYSTEM; RAPID TECHNOLOGICAL CHANGE AND RISK
OF TECHNOLOGICAL OBSOLESCENCE     
 
  The Company is dependent on the successful development and commercialization
of the Company's prenatal screening system. Unfavorable preclinical or
clinical results, failure to obtain regulatory clearances or approvals in a
timely manner, or at all, or failure to gain widespread market acceptance for
the system would have a material adverse effect on the Company's business,
financial condition and results of operations.
   
  The medical device industry, particularly the prenatal testing, diagnostic,
and screening markets, is characterized by rapid and significant technological
change. The sale of the Company's current products is largely dependent upon
the continued use of prenatal testing methodologies that require the location
of fetal cells in metaphase and the karyotyping of chromosomes identified in
the metaphase cells. In addition, the Company's current products require a
testing laboratory to make a large one-time investment, and the availability
of less expensive automated cytogenetic equipment could have a material
adverse effect on the Company's business financial condition, and results of
operations. The Company's future success will depend in large part on the
Company's ability to continue to respond to such changes. There can be no
assurance that the Company will be able to respond to such changes or that new
or improved competing products will not be developed that render the Company's
products obsolete. Product research and development will require substantial
expenditures and will be subject to inherent risks, and there can be no
assurance that the Company will be successful in developing products that have
the characteristics necessary to screen or diagnose particular indications or
that any new product introduced will receive regulatory clearance or approval
or will be successfully commercialized. See "Business--Research and
Development."     
 
                                       8
<PAGE>
 
   
HIGHLY COMPETITIVE MARKET; RISK OF COMPETING SCREENING APPROACHES     
   
  The market for the Company's current cytogenetic products is highly
competitive, and the Company expects competition to increase. With respect to
its current cytogenetic products, the Company's current competitors include
Vysis Corp., a biotechnology subsidiary of Amoco Technology Company,
Perceptive Scientific, Inc. (acquired by International Remote Imaging Systems,
Inc.) and manual laboratory procedures. The market for the Company's current
cytogenetic products is limited to laboratories and institutions performing
prenatal and other genetic testing. There can be no assurance that the
Company's competitive position in cytogenetic products will be maintained.
       
  The medical diagnostic and biotechnology industries are subject to intense
competition. The Company knows of certain companies that are in the process of
developing genetic screening products based on competing technologies designed
to enrich the concentration of nucleated fetal cells in maternal blood
samples. These companies include Integrated Genetics, Inc., CellPro,
Incorporated, Aprogenex, Inc. and Centocor, Inc. Many of the Company's
competitors have greater financial and technical resources and production and
marketing capabilities than the Company. There can be no assurance that these
competitors will not succeed in developing technologies and products that are
more accurate and effective, easier to use or less expensive than those which
are currently offered or being developed by the Company or that would render
the Company's technology and products obsolete and noncompetitive. In
addition, many of the Company's competitors have significantly greater
experience than the Company in conducting clinical investigations of new
screening and diagnostic products and in obtaining FDA and other clearances or
regulatory approvals of products. Accordingly, the Company's competitors may
succeed in developing and obtaining regulatory approvals for such products
more rapidly than the Company. The Company's prenatal screening system under
development, if commercially marketed, will be subject to intense competition
from existing prenatal screening and diagnostic approaches, such as AFP,
triple test, CVS and amniocentesis. These competing approaches are widely
accepted and screen and/or diagnose a broad range of abnormalities. There can
be no assurance that the Company's prenatal screening system under development
will replace or supplement any of these or other existing procedures. Such
competition from new, developing or existing products or failure of the
Company to successfully develop its prenatal screening system would have a
material, adverse effect on the Company's business, financial condition and
results of operations. See "Business--Competition."     
       
UNCERTAINTY OF FDA OR OTHER REGULATORY CLEARANCES OR APPROVALS
   
  The preclinical and clinical testing, manufacturing, labeling, distribution,
sale, marketing, advertising and promotion of the Company's research,
investigational and clinical screening and diagnostic products are subject to
extensive and rigorous government regulation in the United States and certain
other countries. In the United States and certain other countries, the process
of obtaining and maintaining required regulatory clearances or approvals is
lengthy, expensive and uncertain. The Company's future success will be
significantly dependent upon commercial sales of its prenatal screening system
under development. The Company will not be able to market this prenatal
screening system for clinical diagnostic use in the United States unless and
until the Company obtains clearance or approval from the United States Food
and Drug Administration ("FDA") for each device within the system and will not
be able to market such system overseas until it meets the safety and quality
regulations of each foreign jurisdiction in which the Company, its agents or
distributors seek to sell such system. Noncompliance with applicable FDA
requirements can result in severe administrative, civil and criminal
sanctions.     
   
  The Company's Cytoscan products were marketed until 1994 in the United
States pursuant to pre-market notifications to the FDA under Section 510(k) of
the Federal Food, Drug and Cosmetic Act ("510(k)"). A 510(k) pre-market
notification must be supported by appropriate data establishing, to the
satisfaction of the FDA, that a newly developed device is "substantially
equivalent" to a legally marketed device that did not itself require FDA
approval of a premarket approval application ("PMA"). The PMA process is
significantly more complex, expensive and time consuming than the 510(k)
process. The decision whether to seek 510(k) clearance for a changed or
modified device is left to the manufacturer in the first instance. The Company
to date has not sought 510(k) clearance for its CytoVision system, which has
been marketed since 1993, on the basis of the Company's conclusion, reflected
in the Company's scientific report addressing this matter, that CytoVision is
a new model of Cytoscan and there have not been any changes or modifications
in design, components, method of manufacture or intended use, which could
significantly affect the safety or effectiveness of the original 510(k)-
cleared     
 
                                       9
<PAGE>
 
   
Cytoscan device. There can be no assurance that the FDA will agree with the
Company's decision not to seek 510(k) clearance for CytoVision, that it will
not require the Company to cease sales and distribution of and seek 510(k)
clearance for the CytoVision system, or that such clearance, if required, will
be obtained in a timely manner or at all.     
 
  The Company intends to apply for two separate 510(k) clearances for the
fetal cell enrichment and scanning components of its prenatal screening
system. The DNA probe components of the Company's prenatal screening system
will require either FDA clearance of a 510(k) with a tier III level of review
(the most extensive level of FDA review of a 510(k), equivalent to the FDA
review of a PMA in thoroughness and time) or FDA approval of a PMA.
   
  The Company intends to submit a protocol for clinical trials of the DNA
probe component of its prenatal screening system to the FDA before the end of
1996 and to initiate a multisite U.S. and international clinical trial of the
DNA probe component of its prenatal screening system to detect chromosomal
disorders in isolated fetal cells during the first half of 1997, based upon
the response from the FDA. There can be no assurance regarding the timing or
nature of the FDA response regarding the DNA probe related protocol or the
timing for the commencement of clinical trials. There can be no assurance that
510(k) clearance for any portion of the fetal cell screening system under
development or any other future product or modification of an existing product
will be granted or that the clearance process will not be unduly lengthy and
subjected to a thorough internal review equivalent to that ordinarily reserved
for devices requiring premarket approval by the FDA. If substantial
equivalence cannot be established or if the FDA determines that the device or
the particular application for the device requires a more rigorous review,
which the FDA has stated is possible for the Company's prenatal screening
system under development, the FDA will require that the Company submit a PMA
that must be reviewed and approved by the FDA prior to sales, distribution and
marketing of these products in the United States. Currently, the DNA probes
that the Company intends to purchase from third parties to incorporate into
its prenatal screening system are sold on a research basis without FDA
approval for commercial sale. The FDA requires DNA probes to have 510(k)
clearance or PMA approval for commercial sale for clinical diagnostic use,
which could cause the price of DNA probes to increase, making the Company's
prenatal screening system less price competitive compared to existing prenatal
genetic test procedures.     
   
  The regulation of medical devices continues to develop and there can be no
assurance that new laws or regulations will not have a material adverse effect
on the Company's business, financial condition and results of operations.
Delays in receipt of clearance or approvals to market its products, failure to
receive these clearances or approvals, the loss of previously received
clearances or approvals, the determination that 510(k) clearance, pre-market
approval or other approval is required for a product being marketed without
such clearance or approval, or failure to comply with existing or future
regulatory requirements could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--
Government Regulation."     
 
NEED TO COMPLY WITH INTERNATIONAL GOVERNMENT REGULATION
 
  The regulatory review process varies from country to country. Currently, the
Company's products are subject to pre-market approval in several of the
countries that are members of the European Union and subject to other
regulatory requirements in those and other countries. In addition, the
regulation of in vitro diagnostic devices ("IVDs") and other medical devices
continues to change. The Company may rely, in some circumstances, on its
international distributors for compliance with clinical trial requirements in
those countries where the Company intends to use distributors. Any enforcement
action by regulatory authorities with respect to past or future regulatory
noncompliance would have a material adverse effect on the Company's business,
financial condition and results of operations.
   
  The time required to obtain approval for sale in foreign countries may be
longer or shorter than that required for FDA approval, and the requirements
may differ. In addition, there may be foreign regulatory barriers other than
pre-market approval.     
   
  The Company plans to bring its instruments, when required, into compliance
with the European Parliament's Electromagnetic Emissions Requirement
(89/336/EEC) (the "EER") and to be entitled to apply the CE mark, with respect
to the EER, to its instruments. The European Parliament has made a distinction
between Medical Devices (MDs) and IVDs. The Company's instruments are not now
subject to the requirements nor     
 
                                      10
<PAGE>
 
   
advantages of the Medical Device Directive (93/42/EEC). There can be no
assurance, however, that some or all of the Company's products will not be
redefined as MDs and made subject to this Directive by the EU or its member
states, which would have a material adverse effect on the Company's business,
financial condition, and results of operations. Currently the European Union
("EU") and its member states have not adopted an EU-wide directive
specifically regulating IVDs. A "Draft" EU IVD Directive (95/0013/EEC[COD])
has been prepared but has not been adopted into law either in the European
Parliament or by any member state. To the Company's knowledge, there is no
date established at this time for its enactment. Transposition into law in the
member states may take up to two years to five years or longer following
enactment by the European Parliament. Under the terms of the "Draft" IVD
Directive a company (if it is in compliance) would be permitted to self-
certify compliance with 95/0013/EEC[COD] without the intervention of a
Competent Authority (a governmental agency of a member state with jurisdiction
over matters pertaining to the directive) or a Notified Body (a private entity
authorized by a Competent Authority to verify the compliance of a regulated
entity with a particular directive) and thus apply the CE mark to its products
with respect to this Directive. There can be no assurance, however, that the
Draft IVD Directive will be adopted, or if adopted, will be implemented as
drafted, or at all, that if adopted self-certification will be permitted, or
that more extensive and more burdensome requirements will not be imposed under
the IVD Directive (as adopted) or in the laws of the member states when
implemented, or that any such requirements will not have a material adverse
effect on the Company's business, financial condition, or results of
operations. There can be no assurance, moreover, that member states, or any
other European country, will not adopt other statutes or regulations that
require premarket approval of the Company products, or that will otherwise
have a material adverse effect on the Company's business, financial condition,
or results of operations.     
   
DEPENDENCE UPON PATENTS AND PROPRIETARY TECHNOLOGY; RISK OF INFRINGEMENT     
   
  The Company relies on trade secret protection and on its unpatented
proprietary know-how in the development and manufacturing of its products.
While the Company generally enters into confidentiality agreements with its
employees and consultants, there can be no assurance that the Company's trade
secrets or proprietary technology will not become known or be independently
developed by competitors in such a manner that the Company has no practical
recourse. Nor can there be any assurance that others will not develop or
acquire equivalent expertise or develop products which render the Company's
current or future products noncompetitive or obsolete. There can be no
assurance that the claims allowed under its patents will be sufficiently broad
to protect what the Company believes to be its proprietary rights. In
addition, there can be no assurance that issued patents will not be disallowed
or circumvented by competitors, or that the rights granted thereunder will
provide competitive advantages to the Company. Companies have filed
applications for, or have been issued patents relating to, products or
processes that may be competitive with certain of the Company's products or
processes. The Company is unable to predict how the courts would resolve
issues relating to the validity and scope of such patents.     
   
  The validity and breadth of claims in medical technology patents involve
complex legal and factual questions and, therefore, may be highly uncertain.
No assurance can be given that any issued patent or patents based on pending
patent applications or any future patent application will exclude competitors,
that any of the Company's patent or patents in which it has licensed rights
will be held valid if subsequently challenged or that others will not claim
rights in or ownership of the patents and other proprietary rights held or
licensed by the Company. Furthermore, no assurance can be given that others
have not developed or will not develop similar products, duplicate any of the
Company's products or design around any patents issued to or licensed by the
Company or that may be issued in the future to the Company. Since patent
applications in the United States are maintained in secrecy until patents
issue, the Company also cannot be certain that others did not first file
applications for inventions covered by the Company's pending patent
applications, nor can the Company be certain that it will not infringe any
patents that may issue to others on such applications.     
 
  Legislation is pending in Congress that may limit the ability of medical
device manufacturers in the future to obtain patents on surgical and medical
procedures. While the Company cannot predict whether the legislation will be
enacted, or precisely what limitations will result from the law if enacted,
any limitation or reduction in
 
                                      11
<PAGE>
 
the patentability of medical and surgical technology could have a material
adverse effect on the Company's ability to protect its proprietary methods and
procedures.
   
  In addition, patent applications in foreign countries are maintained in
secrecy for a period after filing. Publication of discoveries in the
scientific or patent literature tends to lag behind actual discoveries and the
filing of related patent applications. The Company has not conducted an
extensive search of patents issued to other companies, research or academic
institutions, or others, and no assurances can be given that such patents do
not exist, have not been filed, or could not be filed or issued, which contain
claims relating to the Company's technology, products or processes. Patents
issued and patent applications filed in the United States or internationally
relating to medical devices are numerous and there can be no assurance that
current and potential competitors and other third parties have not filed or in
the future will not file applications for, or have not received or in the
future will not receive, patents or obtain additional proprietary rights
relating to products or processes used or proposed to be used by the Company.
There are pending applications, which if issued with claims in their present
form, might provide proprietary rights to third parties relating to products
or processes used or proposed to be used by the Company. The Company may be
required to obtain licenses to patents or proprietary rights of others.     
 
  The medical device industry in general, and the industry segment that
includes products for prenatal diagnostic screening in particular, have been
characterized by substantial competition. Litigation regarding patent and
other intellectual property rights, whether with or without merit, could be
time-consuming and expensive to respond to and could divert the Company's
technical and management personnel. The Company may be involved in litigation
to defend against claims of infringement by the Company, to enforce patents
issued to the Company, or to protect trade secrets of the Company. If any
relevant claims of third-party patents are held as infringed and not invalid
in any litigation or administrative proceeding, the Company could be prevented
from practicing the subject matter claimed in such patents, or would be
required to obtain licenses from the patent owners of each such patent, or to
redesign its products or processes to avoid infringement. The Company has
recently received a letter from Vysis Corp. informing the Company that its
products might fall within the claims of a United States patent exclusively
licensed to Vysis Corp. Vysis Corp. offered the Company the right to obtain a
sublicense to such patent. The Company does not believe it is necessary to
obtain such a sublicense and does not believe it is infringing the patent .
However, there can be no assurance that the Company will not ultimately be
required to seek a license from Vysis Corp. or any other third party or that
such license would be available or, if available, would be available on terms
commercially-acceptable to the Company. In addition, in the event of any
possible infringement, there can be no assurance that the Company would be
successful in any attempt to redesign its products or processes to avoid such
infringement. Accordingly, an adverse determination in a judicial or
administrative proceeding or failure to obtain necessary licenses could
prevent the Company from manufacturing and selling its products, which would
have a material adverse effect on the Company's business, financial condition
and results of operations. The Company intends to vigorously protect and
defend its intellectual property. Costly and time-consuming litigation brought
by the Company may be necessary to enforce patents issued to the Company, to
protect trade secrets or know-how owned by the Company, or to determine the
enforceability, scope and validity of the proprietary rights of others. See
"Business--Patents and Proprietary Rights" and "--Competition."
   
LIMITED MANUFACTURING EXPERIENCE; NO MANUFACTURING EXPERIENCE FOR THE
CONSUMABLE ENRICHMENT KIT     
   
  To date, the Company's manufacturing activities have consisted primarily of
the assembly and testing of its cytogenetic products. If the Company obtains
necessary regulatory clearances, registrations and approvals for its prenatal
screening system and such systems are successfully introduced, the Company
will be required to increase its manufacturing capacity. The Company has no
experience in manufacturing the consumable enrichment kit portion of its
prenatal screening system. Manufacturers often encounter difficulties in
commencing and increasing production, including problems involving production
yields, adequate supplies of components, quality control and assurance
(including failure to comply with the FDA's and State of California's GMP
regulations, international quality standards and other regulatory
requirements) and shortages of qualified personnel. Difficulties experienced
by the Company in manufacturing could have a material adverse effect on its
    
                                      12
<PAGE>
 
business, financial condition and results of operations. There can be no
assurance that the Company will be successful in commencing manufacture of the
prenatal screening system in commercial quantities, increasing manufacturing
capacity or that it will not experience manufacturing difficulties or product
recalls in the future. See "Business--Manufacturing."
 
  The Company plans to initially subcontract third parties to manufacture the
consumable enrichment kit component of its prenatal screening system under
development and may ultimately manufacture such components on its own. For
clinical trials, the Company will purchase the consumable enrichment kit from
a third party. The Company may encounter difficulties in scaling up production
of the consumable enrichment kit of its prenatal screening system under
development or in hiring and training additional personnel to manufacture its
consumable enrichment kit products in commercial quantities.
   
NEED TO MANAGE GROWTH     
 
  Significant future growth in the Company's sales and expansion in the scope
of its operations, should they occur, may place considerable strain on the
Company's management, financial, manufacturing and other capabilities,
procedures and controls. There can be no assurance that any existing or
additional capabilities, procedures or controls will be adequate to support
the Company's operations or that its capabilities, procedures or controls will
be designed, implemented or improved in a timely and cost-effective manner.
Failure to implement, improve and expand such capabilities, procedures and
controls in an efficient manner at an appropriate pace could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
SINGLE SOURCE COMPONENTS; DEPENDENCE ON KEY DISTRIBUTORS
   
  Certain components of the Company's prenatal screening system under
development are expected to be in consumable enrichment kit form. The Company
intends to initially subcontract the manufacture of such consumable enrichment
kits; however, given the stage of the product's development, neither internal
nor third-party manufacturing processes have been established. The Company
currently relies on a sole supplier for a certain component of its consumable
enrichment kit. There can be no assurance that reliable, high volume
commercial supplies of such component can be established at commercially
reasonable costs or that a new supplier could be qualified in a timely manner
if the supply of such component were interrupted. The Company also relies on a
sole source supplier for its preformed density gradients, an essential
component for its consumable enrichment kit. There can be no assurance that
reliable high volume manufacturing of such gradients can be established at
commercially reasonable costs or that a new supplier could be qualified in a
timely manner if the supply of such gradients were interrupted. In addition,
the Company proposes to incorporate DNA probes into its prenatal screening
system under development, which are currently provided by a limited number of
vendors. The Company has an obligation to purchase certain types of DNA probes
from a particular supplier subject to such supplier meeting various
performance standards. Such probes require FDA clearance or approval for
marketing for clinical diagnostic procedures in the United States and may
require FDA approval for export. The DNA probe market is characterized by
extensive patent litigation and any court order with respect to infringement
of intellectual property could adversely affect the supply of available and
cost-effective DNA probes. While the Company believes that other sources for
such DNA probes are available, if there were to be interruptions in obtaining
supplies from its present source, the Company would have to qualify new
sources of approved supply. Outside of North America and the United Kingdom,
the Company relies substantially on independent distributors and sales agents
to market and sell its products. There can be no assurance that distributors
and agents will devote adequate resources to support sales of the Company's
products. Moreover, agreements with a number of its distributors require that
the Company indemnify such distributors against costs, expenses and
liabilities relating to litigation regarding the Company's products and,
despite these obligations of the company, distributors may decide to reduce or
end their selling efforts until an infringement dispute is resolved or
settled. See "Risk Factors--Patents and Proprietary Technology; Risk of
Infringement," "Business--Applied Imaging's Prenatal Screening System," "--
Current Cytogenetic Products," "--Sales, Distribution and Marketing" and "--
Manufacturing."

RELIANCE ON INTERNATIONAL SALES AND OPERATIONS
   
  The Company has significant international operations based in the United
Kingdom employing approximately 40 employees. In 1993, 1994 and 1995, and in
the six-months ended June 1996 approximately 64%, 62% and 61% and 58%,
respectively, of the Company's total revenues were derived from customers and
distributors outside of the United States and Canada. Until such time, if
ever, as the FDA clears or approves the Company's fetal cell screening system
for marketing in the United States, the Company expects that international
sales of cytogenetic products will continue to account for a significant
portion of its revenues. Changes in overseas economic conditions, currency
exchange rates, foreign tax laws, or tariffs or other trade regulations could
have a material adverse effect on the Company's business, financial condition
and results of operations. The international nature of the Company's business
subjects it and its representatives, agents and distributors to laws and
regulations of the foreign jurisdictions in which it operates or in which its
products are sold. The regulation of medical devices in a number of such
jurisdictions, particularly in the European Community, continue to develop and
there can be no assurance that new laws or regulations will not have a
material adverse effect on the Company's business. The laws of certain foreign
countries may not protect the Company's intellectual property rights to the
same extent as do the laws of the United States. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations," "Business--
Sales, Distribution and Marketing," "--Manufacturing" and "--Facilities."     
   
  Currently, most of the Company's international sales are denominated in U.S.
dollars or the U.K. pound sterling. The Company has significant operations in
the U.K., and therefore, incurs significant operating expenses denominated in
U.K. pounds. Accordingly, the Company has not historically attempted to reduce
the risk of currency fluctuations by hedging, as changes in exchange rates
between the U.S. dollar and the U.K. pound sterling immaterially affect the
Company's results of operations. However, there can be no assurance that the
Company will not be disadvantaged with respect to its competitors operating in
a foreign country by foreign currency exchange rate fluctuations that make the
Company's products more expensive relative to those of local competitors. See
"Business--Sales, Distribution and Marketing."     
 
INTERNATIONAL UNCERTAIN AVAILABILITY OF THIRD-PARTY REIMBURSEMENT; HEALTH CARE
REFORM AND RELATED MATTERS
 
  In the United States, hospitals, physicians and other health care providers
that purchase medical devices generally rely on third-party payors,
principally Medicare, Medicaid, private health insurance plans, health
maintenance organizations and other sources of reimbursement for health care
costs ("Third-Party Payors"), to reimburse all or part of the cost of the
procedure in which the medical device is being used. Certain Third-Party
Payors are moving toward a managed care system in which they contract to
provide comprehensive health care for a fixed cost per person. The fixed cost
per person established by these Third-Party Payors may be independent of the
hospital's cost incurred for the specific case and the specific devices used.
Medicare and other Third-Party Payors are increasingly scrutinizing whether to
cover new products and the level of reimbursement for covered products.
Because the Company's fetal cell screening system is currently under
development and has not received FDA clearance or approval, uncertainty exists
regarding the availability of third-party reimbursement for procedures that
would use the Company's fetal cell screening system. Failure by physicians,
hospitals and other potential users of the Company's products or products
currently under development to obtain sufficient reimbursement from Third-
Party Payors for the procedures in which the Company's products or products
currently under the development are intended to be used could have a material
adverse effect on the Company's business, financial condition and results of
operation.
 
  Third-Party Payors that do not use prospectively fixed payments increasingly
use other cost-containment processes that may pose administrative hurdles to
the use of the Company's products and products currently under development. In
addition, Third-Party Payors may deny reimbursement if they determine that the
device used in a treatment is unnecessary, inappropriate, experimental, used
for a non-approved indication or is not cost-effective. Potential purchasers
must determine that the clinical benefits of the Company's products justify
the additional cost or the additional effort required to obtain prior
authorization or coverage and the uncertainty of actually obtaining such
authorization or coverage.
 
                                      14
<PAGE>
 
  If the Company obtains the necessary foreign regulatory registrations or
approvals, market acceptance of the Company's products and products currently
under development in international markets would be 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. Although the Company intends to seek
international reimbursement approvals, there can be no assurance that any such
approvals will be obtained in a timely manner, if at all. Failure to receive
international reimbursement approvals could have a material adverse effect on
market acceptance of the Company's products in the international markets in
which such approvals are sought.
   
  The Company believes that in the future reimbursement will be subject to
increased restrictions both in the United States and in international markets.
The Company believes that the overall escalating cost of medical products and
services 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 the Company's products and products currently under
development. There can be no assurance in either United States or
international markets that third-party reimbursement and coverage will be
available or adequate, that future legislation, regulation or reimbursement
policies of Third-Party Payors will not otherwise adversely affect the demand
for the Company's products or products currently under development or its
ability to sell its products on a profitable basis. The unavailability of
Third-Party Payor coverage or the inadequacy of reimbursement could have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, fundamental reforms in the health care
industry in the United States and Europe continue to be considered, although
the Company cannot predict whether or when any health care reform proposals
will be adopted and there can be no assurance that such reform will not
materially adversely affect the Company's business, financial condition and
results of operations. See "Business--Third-Party Reimbursement and Health
Care Reform."     
 
DEPENDENCE UPON KEY PERSONNEL
 
  The Company's future success depends in significant part upon the continued
service of certain key scientific, technical and management personnel, and its
continuing ability to attract and retain highly qualified scientific,
technical and managerial personnel. Competition for such personnel is intense
and there can be no assurance that the Company can retain its key scientific,
technical and managerial personnel or that it can attract, assimilate or
retain other highly qualified scientific, technical and managerial personnel
in the future. The loss of key personnel, especially if without advanced
notice, or the inability to hire or retain qualified personnel could have a
material adverse effect upon the Company's business, results of operations and
financial condition.
 
RISK OF SOFTWARE DEFECTS
 
  The Company's cytogenetic products and fetal cell screening system currently
under development involve a software component that facilitates the detection
of chromosomal and genetic abnormalities through the interaction of certain
imaging algorithms with the genetic sample under examination. The software,
including any new versions that may be released, may contain undetected errors
or failures. There can be no assurance that, despite testing by the Company
and current and potential customers, errors will not be found in the software
components of the Company's cytogenetic products or prenatal screening system,
resulting in loss or delay in market acceptance, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
PRODUCT LIABILITY RISK; POSSIBLE INSUFFICIENCY OF INSURANCE
   
  The manufacture and sale of the Company's products involves the risk of
product liability claims. There can be no assurance that the coverage limits
of the Company's insurance policies will be adequate. The Company intends to
evaluate its coverage on a regular basis and in connection with the
introduction of products currently under development. Such insurance is
expensive and may not be available on acceptable terms, in sufficient amount
of coverage, or at all. A successful claim brought against the Company in
excess of its insurance coverage would have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business--Product Liability and Insurance."

CONTROL BY EXISTING STOCKHOLDERS     
   
  After the completion of this offering, current stockholders, including
certain executive officers and directors of the Company and their affiliates,
will own approximately 69.1% of the outstanding Common Stock. As a result,
these stockholders will, to the extent they act together, continue to have the
ability to exert significant influence and control over matters requiring the
approval of the Company's stockholders, including the election of a majority
of the Company's Board of Directors. See "Principal Shareholders."     
   
RISK OF UNALLOCATED PROCEEDS     
   
  The Company expects that it will use a portion of the net proceeds of this
offering for general corporate purposes, including working capital. Of the
approximately $31.3 million net proceeds from this offering, approximately
$15.7 million, or 50%, will be used for such general corporate purposes. The
Company has no specific plans as to the use of the unallocated proceeds from
this offering. Pending use, the Company plans to invest the net proceeds in
investment-grade, interest-bearing securities. Accordingly, management will
have significant discretion in applying a portion of the net proceeds of this
offering. See "Use of Proceeds."     
   
POTENTIAL IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE     
   
  Sales of Common Stock (including shares issued upon the exercise of
outstanding options) in the public market after this offering could materially
and adversely affect the market price of the Common Stock. Such sales also
might make it more difficult for the Company to sell equity securities or
equity-related securities in the future at a time and price that the Company
deems appropriate. Upon the completion of this offering, the Company will have
7,436,064 shares of Common Stock outstanding, of which the 2,300,000 shares
offered hereby will be freely tradeable (unless held by affiliates of the
Company) without restriction. The remaining 5,136,064 shares will be
restricted securities within the meaning of the Securities Act of 1933, as
amended (the "Securities Act"). The Company's directors, executive officers
and certain of its stockholders, who in the aggregate hold more than 94% of
the shares of Common Stock of the Company outstanding immediately prior to the
completion of this offering, have entered into lock-up agreements under which
they have agreed not to sell, directly or indirectly, any shares owned by them
for a period of 180 days after the date of this Prospectus without the prior
written consent of Montgomery Securities. Montgomery Securities may, in its
sole discretion and at any time without notice, release all or any portion of
the shares subject to such lock-up agreements. Of such shares, approximately
271,617 will be freely tradeable (unless held by affiliates of the Company)
without restriction. Upon expiration of the 180-day lock-up agreements,
approximately 4,014,253 additional shares of Common Stock (including
approximately 258,373 shares subject to outstanding vested options) will
become eligible for public resale, subject in some cases to volume limitations
pursuant to Rule 144. The remaining approximately 1,617,301 shares held by
existing stockholders (including up to 508,734 shares of Common Stock issuable
upon exercise of certain outstanding warrants) will become eligible for public
resale at various times over a period of less than two years following the
completion of this offering, subject in some cases to vesting provisions and
volume limitations. In addition, 4,105,674 of the shares outstanding
immediately following the completion of this offering (including up to 508,734
shares of Common Stock issuable upon exercise of certain outstanding warrants)
will be entitled to registration rights with respect to such shares upon
termination of lock-up agreements. The number of shares sold in the public
market could increase if registration rights are exercised and such sales may
have an adverse effect on the market price of the Common Stock. See "Shares
Eligible for Future Sale."     
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK; DILUTION
 
  Prior to this offering, there has been no public market for the Common
Stock. There can be no assurance that an active trading market will develop
and continue upon the completion of this offering or that the market price of
the Common Stock will not decline below the initial public offering price. The
initial public offering price of the Common Stock has been determined by
negotiations between the Company and the Underwriters, in conformity with
Schedule E of the By-Laws of the National Association of Securities Dealers
(the "NASD"). As such, the initial public offering price is not necessarily
related to the Company's net worth or any other
 
                                      16
<PAGE>
 
   
established criteria of value and may not bear any relationship to the market
price of the Common Stock following the completion of the offering. The market
prices for securities of medical diagnostic instrument companies have
historically been highly volatile. Announcements of technological innovations
or new products by the Company or its competitors, developments concerning
proprietary rights, including patents and litigation matters, publicity
regarding actual or potential results with respect to products under
development by the Company or others, regulatory developments in both the
United States and foreign countries and public concern as to the safety of new
technologies changes in financial estimates by securities analysts or failure
of the Company to meet such estimates and other factors, may have a
significant impact on the market price of the Common Stock. In addition, the
Company believes that fluctuations in its operating results may cause the
market price of its Common Stock to fluctuate, perhaps substantially.
Purchasers of shares of Common Stock offered hereby will experience an
immediate dilution of $10.30 in the net tangible book value per share of their
Common Stock from the initial public offering price. See "Underwriting" and
"Dilution."     
   
ANTI-TAKEOVER EFFECT OF DELAWARE LAW AND CERTAIN CHARTER AND BYLAWS PROVISIONS
       
  Certain provisions of the Company's Restated Certificate of Incorporation
and Bylaws may have the effect of making it more difficult for a third party
to acquire, or discouraging a third party from attempting to acquire control
of the Company. Such provisions could limit the price that certain investors
might be willing to pay in the future for shares of the Company's Common
Stock. Certain of these provisions provide for the elimination of the right of
stockholders to act by written consent without a meeting and specify
procedures for director nominations by stockholders and submission of other
proposals for consideration at stockholder meetings. In addition, the
Company's Board of Directors has the authority to issue up to 6,000,000 shares
of Preferred Stock and to determine the price, rights, preferences, privileges
and restrictions of those shares without any further vote or action by the
stockholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The issuance of Preferred Stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult
for a third party to acquire a majority of the outstanding voting stock of the
Company. The Company has no present plans to issue shares of Preferred Stock.
Certain provisions of Delaware law applicable to the Company could also delay
or make more difficult a merger, tender offer or proxy contest involving the
Company, including Section 203 of the Delaware General Corporation Law, which
prohibits a Delaware corporation from engaging in any business combination
with any interested stockholder for a period of three years unless certain
conditions are met. The inability of stockholders to act by written consent
without a meeting, the procedures required for director nominations and
stockholder proposals and Delaware law could have the effect of delaying,
deferring or preventing a change in control of the Company, including without
limitation, discouraging a proxy contest or making more difficult the
acquisition of a substantial block of the Company's Common Stock. These
provisions could also limit the price that investors might be willing to pay
in the future for shares of the Company's Common Stock. See "Description of
Capital Stock--Preferred Stock," "--Certain Provisions of the Restated
Certificate of Incorporation and Bylaws" and "--Certain Provisions of Delaware
Law."

                               THE COMPANY     
   
  The Company was incorporated in California in July 1986, and will be
reincorporated in Delaware in September, 1996. Unless the text otherwise
requires, references in this Prospectus to "Applied Imaging" and the "Company"
refer to Applied Imaging Corp., a California corporation, and its Delaware
successor, together with their subsidiaries. The Company's principal executive
offices are located at 2380 Walsh Avenue, Building B, Santa Clara, California
95051, and its telephone number at that address is (408) 562-0250.     
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $31,335,000 (approximately
$36,147,750 if the Underwriters' over-allotment option is exercised in full)
assuming an initial public offering price of $15.00 per share and after
deducting the estimated underwriting discounts and commissions and estimated
offering expenses.
   
  The Company estimates that approximately $10 million of the net proceeds
from this offering will be used for the development and commercialization of
the Company's prenatal screening system, including costs related to clinical
trials and regulatory approvals, approximately $5 million will be used to fund
research and development related to additional applications of its prenatal
screening technology, an aggregate of $596,000 will be used for repayment of
the Company's bank line of credit bearing interest at 9.75% due in September
1996 and the Company's bank note payable bearing interest at 9.50% due in
October 1996, and the remainder will be used for working capital and general
corporate purposes. Although the Company believes the proceeds of this
offering, together with its existing resources will be adequate to satisfy its
capital needs through 1998, the timing and amount of spending of such capital
resources cannot be accurately determined at this time and will depend upon
several factors, including the timing of regulatory approvals or clearances,
progress of its research and development efforts and clinical investigations,
competing technological and market developments, commercialization of products
currently under development, and market acceptance and demand for the
Company's products. The Board of Directors has broad discretion in determining
how the proceeds of this offering will be applied. In the event opportunities
arise, proceeds also may be used to acquire businesses, technologies or

                                   DILUTION
   
  The pro forma net tangible book value of the Company as of June 30, 1996 was
approximately $3,590,000 or $.70 per share of Common Stock. Pro forma net
tangible book value per share represents the Company's total tangible assets
less total liabilities, divided by the pro forma number of outstanding shares
of Common Stock (after giving effect to the conversion of the Preferred Stock
to Common Stock). Dilution per share represents the difference between the
amount per share paid by investors in this offering and the pro forma net
tangible book value per share after the offering. After giving effect to the
sale of 2,300,000 shares in this offering at an assumed initial public
offering price of $15.00 per share and after deducting the estimated
underwriting discounts and commissions and offering expenses, the pro forma
net tangible book value of the Company as of June 30, 1996 would have been
$34,925,000 or $4.70 per share. This represents an immediate increase of net
tangible book value of $4.00 per share to existing stockholders and an
immediate dilution in net tangible book value of $10.30 per share to new
investors purchasing shares at the assumed initial public offering price. The
following table illustrates this per share dilution:

  The computations in the above table (i) are determined before deducting
estimated underwriting discounts and commissions and offering expenses payable
by the Company, (ii) assume no exercise of outstanding stock options, and
(iii) assume the conversion of all outstanding shares of Preferred Stock into
Common Stock upon the closing of this offering, and (iv) assume the net
exercise of certain outstanding warrants into 85,387 shares of Common Stock.
As of June 30, 1996, there were options outstanding to purchase 497,250 shares
of Common Stock at a weighted average exercise price of $1.95 per share under
the Company's 1988 Option Plan. As of June 30, 1996, there were warrants
outstanding to purchase 508,734 shares of Common Stock at a weighted average
exercise price of $4.97 per share. To the extent outstanding options are
exercised or warrants are further exercised, there will be further dilution to
new investors. See "Management--Incentive Stock Plans," "Description of
Capital Stock--Warrants" and "Underwriting."

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements that involve
risks and uncertainties. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including those set forth under "Risk Factors" and elsewhere
in this Prospectus.
 
OVERVIEW
   
  Since its inception in 1986, the Company has principally been engaged in the
design, development, manufacture and marketing of automated clinical analysis
systems used by cytogenetic laboratories for prenatal and other genetic
screening. The Company's cytogenetic instrumentation products include systems
that enable laboratories to automate aspects of the detection of chromosomal
abnormalities associated with conditions such as Down's Syndrome. The
Company's CytoVision family of products includes an automated metaphase finder
which identifies cells in metaphase, a karyotyper which automates the
classification and presentation of chromosomes within cells and a DNA probe
analysis system which detects DNA probes within cell nuclei. The Company sells
its cytogenetic systems to government and private clinical cytogenetic
laboratories, research institutions, universities and pharmaceutical
companies, and has sold such systems to approximately 500 sites in over 30
countries.     
 
  Historically, the Company has grown through both internal expansion and
acquisitions. In 1989 and 1991, the Company acquired two separate companies
based in the United Kingdom with complementary technologies and worldwide
market presence. In 1991, the Company restructured its U.K. operations to
combine the two acquired companies. In 1993, the Company eliminated certain
unprofitable product lines in order to focus its efforts on the cytogenetic
screening market.
   
  In 1993, the Company established a research project to develop a proprietary
prenatal screening system to detect chromosomal genetic disorders through the
enrichment and analysis of fetal blood cells from a routine maternal blood
sample. Since that time, the Company has devoted substantial resources to the
development of this prenatal screening system. The Company's proprietary
screening system, which the Company is developing, incorporates (i) a patented
hematologically-based procedure to enrich and separate the fetal blood cells,
(ii) automated image analysis instrumentation to identify the fetal cells and
(iii) the use of third-party DNA probes to identify certain chromosomal
disorders present in fetal cells. This prenatal screening system under
development is currently in preclinical evaluation, and the Company intends to
continue preclinical and clinical evaluation of this system to establish it as
a broadly applicable prenatal screening procedure. The Company anticipates
that sales of this system, if cleared or approved by the FDA, will include
both a consumable enrichment kit used to separate fetal blood cells from
maternal blood and imaging instrumentation used to analyze these cells. The
implementation of the Company's strategy is dependent upon the successful
development and commercialization of the Company's prenatal screening system.
       
  The operating results of the Company have fluctuated significantly in the
past on an annual and quarterly basis. The Company expects that its operating
results will fluctuate significantly from quarter to quarter and year to year
in the future and will depend on a number of factors, some of which may affect
future sales of the Company's cytogenic products. These factors include, but
are not limited to, demand for the Company's products, timing of orders and
shipments, competition and its related pricing pressures, and seasonal
factors, many of which are outside the Company's control. If FDA clearance or
approval is received, the Company intends to increase the amount of
expenditures for research and development and sales and marketing activities,
principally for the commercial launch of its prenatal screening system. The
Company intends to increase its research and development expenses related to
follow-on products and additional applications of its fetal cell screening
technology. The Company also intends to increase the amount of expenditures
related to marketing and administrative activities. Management's plans
discussed above assume the receipt of the net proceeds of this offering.

RESULTS OF OPERATIONS     
   
SIX MONTHS ENDED JUNE 30, 1996 AND 1995     
   
  Revenues. The Company's revenues are derived primarily from the sale of
products and software maintenance and instrument service contracts. Revenues
increased by 15% to approximately $6.0 million for the six months ended June
30, 1996 from $5.2 million for the corresponding period of the prior year.
This increase in revenues was primarily attributable to sales of the Company's
CytoVision products to both new and existing customers, who were either adding
capacity or replacing earlier generation systems. Software maintenance and
service contract revenue as a percentage of total revenue decreased to 22% for
the six months ended June 30, 1996 from 25% for the corresponding period of
the prior year. This decrease was primarily attributable to an increased rate
of new system sales. Revenues from new system sales are recognized upon
shipment, whereas revenues from the related maintenance and service contracts
are deferred and recognized ratably over one year.     
   
  Cost of Revenues. Cost of revenues includes direct material and labor costs,
manufacturing overhead, installation costs, warranty related expenses and
post-warranty service and application support expenses. Cost of revenues as a
percentage of total revenues increased to 52% for the six months ended June
30, 1996 from 50% in the corresponding period of the prior year, due to an
inventory provision taken in the 1996 period relating to a component upgrade
and an increase in service and application support expenses.     
   
  Research and Development Expenses. Research and development expenses consist
of development of new products and software development costs to upgrade
existing products. Research and development expenses increased by 23% to $1.7
million for the six months ending June 30, 1996 from $1.4 million in the
corresponding period of the prior year. This increase was attributable to
increased expenditures in 1996 for the development of the prenatal screening
system.     
   
  Sales and Marketing Expenses. Sales and marketing expenses consist primarily
of salaries, commissions and related travel expenses of the Company's direct
sales force, as well as commissions paid to independent sales agents. Sales
and marketing expenses increased by 11% to approximately $1.5 million for the
six months ended June 30, 1996 from approximately $1.3 million for the
corresponding period of the prior year. This increase was related to the
incremental revenues during the six months ended June 30, 1996 as compared
with the corresponding period of the prior year.     
   
  General and Administrative Expenses. General and administrative expenses
consist primarily of payroll costs associated with the Company's management
and support personnel, travel expenses, and legal and accounting fees. General
and administrative expenses decreased by 5% to $949,000 for the six months
ended June 30, 1996 from $996,000 in the corresponding period of the prior
year. This decrease was primarily attributable to stock option compensation
recorded in the six months ended June 30, 1995 relating to a transaction with
certain officers that took place during that period.     
 
YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
  Revenues. Revenues increased to $10.8 million in 1995 from $9.6 million in
1994, and from $8.7 million in 1993, or annual increases of 13% and 10%,
respectively. The 1995 and 1994 increases in revenues were primarily
attributable to the introduction of the new CytoVision family of products in
the fourth quarter of 1993. Software and service contract revenues as a
percentage of total revenues remained relatively consistent from 1994 to 1995
at 27% and 25% of total revenues, respectively. In 1993, software and service
contract revenues were 29% of total revenues due to higher priced service
contracts associated with earlier-generation products. For the years ended
1995, 1994 and 1993, revenues derived outside of North America represented
approximately 61%, 62% and 64% of total revenues, respectively.
   
  Cost of Revenues. Cost of revenues increased to $5.5 million in 1995 from
$5.4 million in 1994 and from $5.0 million in 1993, or 51%, 56% and 57% as a
percentage of total revenues, respectively. This decrease in revenues as a
percentage of total revenues increased to 52% for the six months ended June
30, 1996 from 50% in the corresponding period of the prior year, due to an
inventory provision taken in the 1996 period relating to a component upgrand
and an increase in service and application support expenses.     
 
                                      23
<PAGE>
 
   
  Research and Development Expenses. Research and development expenses
increased to approximately $2.9 million in 1995 from $2.8 million in 1994 and
from $1.8 million in 1993. These year to year increases were due to increasing
expenditures on the development of the prenatal screening system which were
partially offset by reduced expenditures on the base cytogenetic
instrumentation business. cost of revenues as a percentage of revenues from
year to year was attributable to increased sales volume, engineering design
changes to reduce production costs, and the consolidation of worldwide
manufacturing operations in 1994.     
       
  Sales and Marketing Expenses. Sales and marketing expenses increased to $2.9
million in 1995 from $2.5 million in 1994, which remained unchanged from 1993.
In 1995, 1994 and 1993, sales and marketing expenses as a percentage of total
revenues remained relatively consistent ranging from 26% to 29%.
 
  General and Administrative Expenses. General and administrative expenses
increased to $2.1 million in 1995, from $1.9 million in 1994, and from $1.2
million in 1993, or 19%, 20% and 14% of total revenues, respectively. This
increased level of general and administrative expenses in 1994 was
attributable primarily to costs associated with the Company's effort to
complete an initial public offering, which was abandoned due to unfavorable
market conditions. In addition, the 1994 amounts include certain patent and
legal costs associated with the prenatal screening system and expenses related
to the addition of quality assurance and regulatory personnel.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  From inception in July 1986 through June 1996, the Company has generated an
accumulated deficit of approximately $10.4 million. The Company has financed
its operations primarily through the private placement of equity securities
and bank loans. From its inception, the Company has raised a total of
approximately $14.9 million in net proceeds from such private equity
financings. The Company's primary uses of cash were to fund working capital
requirements, for capital expenditures and to consummate acquisitions of
companies with complementary products, technology, and marketing and sales
organizations.     
   
  Net cash used for operating activities was $1.9 million in the six months
ended June 30, 1996 and $593,000, $1.2 million and $1.0 million for 1995, 1994
and 1993, respectively. For the six months ended June 30, 1996, accounts
receivable increased to $2.1 million from $1.5 million at 1995 year end,
reflecting a slight increase in accounts receivable aging, coupled with the
effect of a 15% increase in revenues over the corresponding prior year period.
For the year ended 1995, the Company had an approximate $2.5 million net loss,
which was offset to a large extent by $556,000 in depreciation and
amortization expenses, a $439,000 decrease in trade accounts receivable, a
$253,000 decrease in inventories, and a $497,000 increase in accrued expenses.
Despite the 13% increase in the Company's revenues in 1995, accounts
receivable decreased 23% to $1.5 million at the end of 1995 from $1.9 million
at the prior year end. This decrease was primarily attributable to a
significant reduction in accounts receivable aging due to increased collection
efforts. In addition, inventories decreased 22% to $880,000 at the end of 1995
from $1.1 million at the prior year end. Significant factors contributing to
this inventory decrease include the consolidation of worldwide manufacturing
activities and the introduction of the CytoVision product family in 1994, both
of which substantially reduced direct material costs. Accrued expenses totaled
$1.4 million at the end of 1995, a 70% increase over the $839,000 level at the
end of 1994. This increase was primarily attributable to accrued compensation
costs, consisting of bonus accruals and a significant severance accrual which
were paid for the most part, during the first quarter of 1996. In addition,
the Company had customer deposits totaling $198,000 as of December 31, 1995.
       
  Net cash used for investing activities has been primarily impacted by the
purchases and subsequent sales of short-term investments in U.S. Treasury
instruments with varying maturities. Such purchases have resulted from
investment of private placement proceeds in excess of short-term cash
requirements. In the six months ended June 30, 1996, net cash provided by
investing activities was $720,000, which consisted of the $972,000 maturity of
a short-term investment offset in part by $300,000 in capital expenditures.
For the year ended December 31, 1995, net cash used by investing activities
was $3.8 million, $3.0 million of which was related to the purchase of such
U.S. Treasury instruments following the Company's most recent private equity
financing. In addition, the Company invested $808,000 in capital expenditures.
For the year ended December 31, 1994, net cash provided by investing
activities was $2.5 million primarily attributable to the maturity of $3.4
million in short-term investments purchased during the prior year, offset in
part by $653,000 in capital expenditures and $259,000     
 
                                      24
<PAGE>
 
   
associated with the purchase of real property. Net cash used by investing
activities was $4.0 million for the year ended 1993, $3.4 million of which was
related to the purchase of U.S. Treasury instruments following a private
equity financing.     
   
  Net cash provided by financing activities was $183,000 for the six months
ended June 30, 1996, and $4.0 million, $389,000 and $4.9 million in 1995, 1994
and 1993, respectively. The significant contributions of cash from financing
activities occurred as a result of the Company's sale of preferred stock in
private rounds of financing in 1993 and again in 1995. Less significantly,
cash provided by or used for financing activities has been impacted by bank
borrowings or repayment of such debt.     
   
  The Company currently has a $1.0 million credit facility with a U.S. bank
consisting of a term note and revolving credit line, of which approximately
$596,000 was outstanding as of June 30, 1996. Under the line of credit
agreement, the Company cannot pay cash dividends without the bank's prior
approval. The term note, which matures in October 1996 and is subject to
monthly payments of principal and interest, bears interest at the bank's prime
rate plus 1.25% (9.50% at June 30, 1996). The line of credit bears interest at
the bank's prime rate plus 1.5% (9.75% at June 30, 1996). The credit line
expires by its current terms in September 1996 and the Company expects to
negotiate a new bank credit facility after the closing of the offering made
hereby. This credit line is currently secured by the Company's domestic
assets, including two-thirds of the shares of Applied Imaging International,
Ltd. held by the Company. See Note 5 of Notes to Consolidated Financial
Statements. The Company's wholly-owned subsidiary, Applied Imaging
International, Ltd. has a (Pounds)500,000 ($775,000) unsecured line of credit
with a United Kingdom bank guaranteed by the Company. No amounts were
outstanding under this facility as of June 30, 1996.     
   
  As of June 30, 1996 cash equivalents and short-term investments were
approximately $3.2 million, compared to approximately $5.2 million as of
December 31, 1995. As of June 30, 1996, the Company also had approximately
$189,000 available under its secured domestic line of credit and
(Pounds)500,000 ($775,000) available under its unsecured international line of
credit. Based upon its current plans, the Company believes the proceeds of
this offering, together with its existing resources, will be adequate to
satisfy its capital needs through 1998. The timing and amount of spending of
such capital resources cannot be accurately determined at this time and will
depend on several factors, including, but not limited to, the progress of its
research and development efforts and clinical investigations, the timing of
regulatory approvals or clearances, competing technological and market
developments, commercialization of products currently under development, and
market acceptance and demand for the Company's products. In addition, as
opportunities arise, proceeds may also be used to acquire businesses,
technologies or products that complement the business of the Company, although
the Company is not currently in negotiations regarding any such acquisitions.
The Company may seek to obtain additional funds through equity or debt
financing, collaborative or other arrangements with other companies and from
other sources. After December 1998, the Company will likely need to raise
additional funds through public or private financings. No assurance can be
given that additional financing will be available when needed or on terms
acceptable to the Company. If adequate funds are not available, the Company
could be required to delay development or commercialization of certain of its
products, to license to third parties the rights to commercialize certain
products or technologies that the Company would otherwise seek to
commercialize itself, or to reduce the marketing, customer support or other
resources devoted to certain of its products.     
   
  The Internal Revenues Code of 1986 and the California Conformity Act of 1987
substantially restrict the ability of a corporation to utilize existing net
operating losses carryforwards and credits in the event of an "ownership
change." The several issuances of preferred stock have resulted in multiple
ownership changes since the inception of the Company. The majority of the
federal net operating loss carryforwards are limited by an ownership change
occurring in July 1995. Approximately $6,700,000 of the $7,700,000 federal net
operating loss carryforward will be subject to an annual limitation of
$850,000. Any unused annual limitation can be carried over and added to the
succeeding year's annual limitation within the allowable carryforward period.
Management believes that the initial public offering of the Company's stock
will most likely result in an ownership change, however, the July 1995 change
will continue to be the most restrictive limitation because the majority of
the Company's net operating losses were incurred prior to July 1995.

                                   BUSINESS
 
  The following Business section contains forward-looking statements which
involve risks and uncertainties. The Company's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including those set forth under "Risk Factors," and
elsewhere in this Prospectus.
 
THE COMPANY
   
  Applied Imaging designs, develops, manufactures and markets automated
clinical analysis systems used by cytogenetic laboratories where prenatal and
other genetic testing is performed. The Company's cytogenetic instrumentation
business, which has sold systems to approximately 500 sites in more than 30
countries since its inception, includes systems that enable laboratories to
automate aspects of the detection of chromosomal abnormalities associated with
conditions such as Down's Syndrome. In addition to the Company's core
instrument business, the Company is developing a proprietary genetic screening
system designed to enable prenatal screening for genetic abnormalities by
isolating fetal red blood cells ("fetal blood cells") from a routine maternal
blood sample. This new system is designed to improve current prenatal
screening techniques by providing an accurate, timely and cost-effective
procedure without the risks of miscarriage or fetal damage associated with
invasive prenatal testing.     
   
  The Company's prenatal screening system under development is intended to
provide an accurate, non-invasive test by directly analyzing fetal blood cells
isolated from a routine maternal blood sample. The Company's proprietary
screening system incorporates (i) a patented blood-based procedure to enrich
the concentration of fetal blood cells, (ii) automated image analysis
instrumentation to identify the fetal blood cells and (iii) the use of third-
party DNA probes to identify certain chromosomal disorders present in fetal
blood cells. This system is expected to be accurate because it evaluates
actual fetal cells while posing no risk to the fetus. The Company's prenatal
screening system is currently in preclinical evaluation and no application for
FDA approval has been submitted.     
   
  The Company's strategy is to establish its system as a broad-based prenatal
screening procedure. The Company anticipates that sales of this system, if
approved by the FDA, will include both its proprietary consumable enrichment
kits, used to separate fetal blood cells from maternal blood samples and
imaging instrumentation used to analyze the cells. These new image analysis
systems are contemplated to be compatible with the Company's existing
installed cytogenetic instrument base. The Company believes that it can
leverage its existing infrastructure, worldwide distribution capabilities and
extensive cytogenetic laboratory relationships to support the world-wide
introduction of this fetal cell screening system under development.
Furthermore, the Company believes that its new cell enrichment and image
analysis system could have clinical utility for cancer applications and the
prenatal diagnosis of single gene disorders, and it intends to pursue the
development of these other potential applications.     
 
GENETIC DISORDERS
 
  All genetic information in an organism is contained in chromosomes, made up
of strands of DNA and associated protein molecules. DNA is comprised of paired
nucleotide bases, and genetic information is encoded by the specific order of
the nucleotide bases within units called genes. Genes are organized linearly
along the chromosomes and carry the required information for the synthesis of
the proteins that provide the structural components of cells and tissues, as
well as enzymes for the basic biochemical and physiological functions of the
cells.
 
 Chromosomal Disorders
 
  The nuclei of normal human cells (except sperm and egg cells) contain two
sets of 23 different chromosomes, one set provided by each parent. Sperm and
egg cells are formed in a special cell division process called meiosis, and
they each contain only one set of the 23 individual chromosomes. When these
cells unite during fertilization, each contributes its set of 23 chromosomes
to the genetic information for a new human fetus, and the fertilized egg then
has the two sets of 23 chromosomes. Chromosomal disorders may occur when genes
 
                                      26
<PAGE>
 
   
or portions of genes move between chromosomes (chromosomal translocations) ,
when portions of chromosomes and the genes they contain are missing, or when
an abnormal number of chromosomes are present in the cell. Certain chromosomal
disorders are thought to occur during meiosis when the division of the
chromosomes to form the egg cell or the sperm cell takes place. During this
process the chromosomes may not divide properly resulting in an extra
chromosome being present in the cell, an extra piece of genetic material being
attached to a chromosome, or a piece of chromosome being broken.     
 
  Chromosomes can be seen under a light microscope and, when stained with
certain dyes, reveal light and dark bands reflecting regional variations of
certain paired bases comprising the DNA of the cell. Differences in size and
banding pattern allow the chromosomes to be distinguished from each other and
can be used to identify a chromosomal disorder. The most common chromosomal
disorder, Down's Syndrome, also known as Trisomy 21, occurs when there are
three copies of chromosome 21 in the human cell. Syndromes caused by various
chromosomal abnormalities may result in mental retardation, impaired physical
development and abnormal sexual development.
 
  There are approximately four million births in the United States annually.
Of these, approximately 90% are to women under the age of 35. The Company
estimates that there are approximately 11 million births in industrialized
countries where prenatal screening and diagnostic testing is routine.
Approximately 2% of newborns have birth defects, approximately 12% of which
are caused by chromosomal genetic disorders. The risk of bearing a child with
a chromosomal abnormality increases with maternal age and more than doubles
from one in 526 births for mothers of age 20 to more than one in 192 births
for mothers of age 35.
 
 Single Gene Disorders
 
  In addition to chromosomal disorders caused by translocations or an abnormal
number of chromosomes, single gene disorders may occur when the DNA sequences
of individual genes are altered, resulting in incorrect instructions to the
cells and disruption of the normal balance or function of essential proteins.
Single gene disorders are responsible for many inherited diseases such as
cystic fibrosis, sickle cell anemia, Tay-Sachs disease, and may predispose an
individual to cancer, psychiatric illnesses, and other complex diseases.
 
PRENATAL TESTING
   
  Prenatal testing is the process of detecting certain types of chromosomal
disorders in a fetus at an early stage of pregnancy. Prenatal testing is
currently performed either invasively, by extracting fetal cells or cells
having fetal-cell characteristics and inspecting the chromosomes within such
cells to diagnose chromosomal disorders, or non-invasively, by an analysis of
a maternal blood sample ("serum test").     
   
  The invasive diagnostic procedures yield accurate results on a broad range
of chromosomal disorders because actual fetal cells are obtained and analyzed,
however, these procedures involve the risk of spontaneous miscarriage and
other risks. Due to the risk of spontaneous miscarriage, invasive diagnostic
procedures are usually recommended to only those women who are age 35 or
older, at which ages the risk of having a child with a chromosomal disorder is
greater than the risk of spontaneous miscarriage due to the procedure. Those
women younger than 35 may be screened using non-invasive techniques. For this
group, an invasive diagnostic procedure is generally only recommended to
confirm the result of the non-invasive serum test if such test indicates a
heightened risk of a chromosomal disorder. The serum tests present no risk to
the fetus, but are less accurate because they do not diagnose chromosomal
genetic disorders by direct analysis of fetal cells. Such tests have a
relatively high false negative rate resulting in the failure to identify a
significant portion of chromosomal disorders.     
 
  Women under the age of 35 have a lower risk of giving birth to an infant
with a chromosomal disorder than do women age 35 or older, but because the
number of births to women under the age of 35 is significantly higher, the
total number of newborns with chromosomal disorders born to women in this age
group is higher than that of women age 35 and older. Consequently, women
younger than 35 bear over 75% of infants with Down's Syndrome. The graph below
illustrates the number of chromesomally abnormal U.S. birth per year by
maternal age:

                  showing absolute number of chromosomally
                      abnormal births by maternal age.] 
 
 
  The most common prenatal testing procedures are described below.
 
 Invasive Diagnostic Procedures
 
  Amniocentesis. Amniocentesis, usually performed between the 14th and 20th
weeks of pregnancy, is the most common procedure used to obtain fetal cell
samples for prenatal genetic testing. In an amniocentesis procedure a small
amount of amniotic fluid is withdrawn from the amniotic sac via a long needle
inserted through the mother's abdominal wall. Simultaneously during the
procedure, the physician uses ultrasound to guide the needle in order to
minimize potential harm to the unborn child. Once the amniotic sample is
extracted, it is forwarded to a cytogenetic laboratory, where the cells are
cultured and deposited on a slide. The slide is then examined under a
microscope in order to locate and analyze a number of fetal cells in metaphase
(undergoing cell division). In metaphase, a cell's chromosomes are
individually visible in its nucleus.
 
  To find a cell in metaphase a laboratory technician scans the slide manually
to locate cells in metaphase. Once metaphase cells are found, they are
photographed using a camera attached to the microscope. This photograph is
printed and each photographed chromosome is manually cut out of the
photograph, arranged in order and pasted on a sheet to show the two sets of 23
chromosomes present in the cell. This presentation of the chromosomes is
called a karyotype. Alternatively, laboratories may eliminate manual
karyotyping by using an automated computer-based karyotyping system to scan
the slides to locate cells in metaphase, classify the chromosomes, present
them in a display and print hard copies.
 
  Once the karyotype is completed it is then visually analyzed by a trained
geneticist or genetic counselor to determine if any chromosomal abnormalities
are present. The processing and analysis of prenatal genetic samples obtained
by amniocentesis generally requires seven to 14 days. A significant portion of
this time is required to culture the fetal cell samples obtained by the
procedure.
 
                                      28
<PAGE>
 
   
  Spontaneous miscarriage occurs in approximately one in every 200
amniocentesis procedures. As a result, only pregnant women who are in a high-
risk group are regularly tested using amniocentesis. In the United States,
amniocentesis generally costs approximately $1,000 per procedure. With an
estimated fetal loss rate of approximately 0.5%, (one in every 200) one normal
fetus will be lost by spontaneous miscarriage resulting from amniocentesis for
every one-to-two fetuses with chromosomal disorders detected by this procedure
for women at age 35.     
 
  Amniocentesis is the most common and accurate of all prenatal screening
procedures. All principal chromosomal disorders can be detected and the Down's
Syndrome detection rate is greater than 99%.
   
  Chorionic Villus Sampling (CVS). CVS, typically performed between the 9th
and 11th weeks of pregnancy, involves the extraction of placental tissue
samples, generally through the pregnant woman's cervix. The tissue, which is
genetically representative of the fetus, is analyzed in the same manner as the
fetal cells obtained by amniocentesis to determine if chromosomal disorders
are present. CVS is an alternative to amniocentesis and can be performed
earlier in the pregnancy, but poses a risk of miscarriage that is one in every
100 CVS procedures, double that of amniocentesis. CVS is generally as accurate
as amniocentesis for detecting chromosomal abnormalities. The cost of the CVS
procedure is approximately $1,000. With an estimated fetal loss rate of
approximately 1% (one in every 100), two normal fetuses will be lost by
spontaneous miscarriage resulting from CVS for every one-to-two fetuses with
chromosomal disorders detected by this procedure for women at age 35. Due to
its higher associated risk, CVS is used less frequently than amniocentesis.
    
 Non-invasive Screening Procedures
 
  In the United States, approximately 2,000,000 pregnant women under the age
of 35 are screened for chromosomal disorders. Of those screened, a majority
are screened using non-invasive serum tests due to the risk associated with
invasive prenatal diagnostic procedures.
 
  Alpha-fetoprotein Test. A common serum prenatal screening test for certain
chromosomal disorders involves the analysis of alpha-fetoprotein ("AFP") in
the maternal blood. This test is performed on a standard blood sample taken
from the mother that is tested for levels of serum AFP. Down's Syndrome and
other similar chromosomal disorders are associated with low levels of AFP.
Although this serum test is relatively accurate in detecting open neural tube
defects (such as spina bifida), studies indicate that the AFP test can detect
only 20-30% of fetuses with Down's Syndrome.
   
  Triple Test. In recent years, the accuracy of the AFP test has been improved
by combining it with additional blood chemistry tests. This combination is
commonly referred to as "triple marker screening" or the "triple test." This
test identifies Down's Syndrome in 60% of the pregnancies where Down's
Syndrome is present. In 40% of the cases where Down's Syndrome is present,
this test inaccurately concludes Down's Syndrome is not present (a false
negative result). And in approximately 5% of the cases, the triple test
indicates the presence of Down's Syndrome where Down's Syndrome is not present
(a false positive result).     
   
  Women whose serum screening results indicate a heightened risk of
chromosomal disorder are usually recommended to have an amniocentesis to
confirm these results. Due to the high false positive rate of the triple test,
amniocentesis procedures are performed in many cases where no chromosomal
disorder exists. Assuming two million serum screening tests per year and a 5%
false positive rate, as many as 100,000 unnecessary procedures may be
performed on women with healthy fetuses each year in the U.S. In addition,
assuming an average cost of $1,000 per amniocentesis, the unnecessary cost to
the health care system associated with these false positive results could be
as high as $100 million per year. With an estimated fetal loss rate of 0.5%
approximately 500 normal fetuses could be lost each year due to unnecessary
amniocentesis procedures.

  The most accurate prenatal testing involves direct analysis of fetal cells,
which contain the chromosomes of the fetus. The only commercially-available
procedures to extract fetal cells in order to examine the fetal chromosomes
are invasive and pose risks of injury to the fetus and spontaneous
miscarriage. The non-invasive serum screening procedures, which do not pose
such risks, are much less accurate because they do not allow direct
examination of fetal chromosomes. The Company believes that there is a
significant need for a prenatal testing procedure which would allow direct
analysis of the fetal cells without the risks associated with the currently-
available invasive procedures.
   
  Fetal blood cells exist in miniscule proportions in samples of maternal
blood. In contrast to adult red blood cells, many of these fetal red blood
cells are nucleated, that is they contain a nucleus with chromosomes. A number
of companies are attempting to isolate these fetal blood cells for testing
through a variety of methods, including various combinations of
immunologically based separation techniques that use monoclonal antibodies,
flow cytometry, or magnetic separation techniques. Although the feasibility of
genetic analysis of fetal blood cells isolated from maternal blood has been
demonstrated, obtaining a sufficient number of fetal blood cells for analysis
has been difficult and generally not suitable to routine clinical
applications.     
 
APPLIED IMAGING'S PRENATAL SCREENING SYSTEM
   
  The Company is developing a proprietary prenatal screening system to detect
chromosomal abnormalities by identifying fetal blood cells from a routine
maternal blood sample. The Company's proprietary screening system incorporates
(i) a patented hematologically-based procedure to enrich the concentration of
fetal blood cells utilizing the Company's consumable enrichment kit, (ii)
automated image analysis instrumentation to identify the fetal blood cells and
(iii) the use of third-party DNA probes to identify certain chromosomal
disorders present in fetal blood cells. This new system is designed to improve
current prenatal screening techniques by providing an accurate, timely and
cost-effective procedure without the risks of miscarriage or fetal damage
associated with invasive prenatal screening techniques.     
 
  In contrast to immunologically-based procedures to isolate fetal blood cells
from maternal blood, the Company is developing a proprietary hematologically-
based procedure for enriching the concentration of fetal blood cells from
maternal blood samples for prenatal genetic testing. The Company's process for
enriching the
 
                                      30
<PAGE>
 
   
concentration of fetal blood cells from a maternal blood sample involves the
following steps: (i) a centrifugation step for bulk separation of the blood
components, utilizing the Company's patented device which removes the vast
majority of the maternal blood cells; (ii) a selective lysis process that
ruptures the remaining maternal red blood cells; and (iii) a second
centrifugation step to remove the majority of maternal white blood cells using
the Company's patented preformed density gradient medium. The enrichment
process is designed to increase the concentration of fetal blood cells in a
maternal sample approximately 10,000 times. The fetal cell enriched sample is
then harvested and deposited on a slide for examination through image analysis.
The Company has developed an automated system to rapidly (under one hour)
identify fetal cells on the slide based on adaptations of its image analysis,
pattern recognition, and slide-scanning technologies incorporated in the
Company's current cytogenetic products. See "Business--Current Cytogenetic
Products."     
 
  Once fetal cells are located by the automated scanning system, fluorescent
DNA probes are added that specifically bind to certain DNA sequences within the
fetal cells indicating the presence or absence of chromosomal disorders. DNA
probes can be designed to locate specific chromosomal changes, additions, or
deletions that result in genetic disorders. The results of the DNA probe
analysis are captured and processed using the Company's automated visualization
technology for the detection, analysis, and documentation of the DNA probe
results. The Company's prenatal screening system is illustrated below:
 
 
                           [ART GRAPHIC APPEARS HERE]

                       [Graphic depicts the steps in the
                     Company's prenatal screening system].
 
 
 
 Preclinical Data
   
  The Company believes that a key aspect of its prenatal screening system is
its ability to enrich and identify fetal blood cells so that they can be
directly analyzed using available DNA probe technology. As of August 1996, the
Company and its collaborators have used its fetal cell enrichment procedure on
a total of 133 maternal blood samples at sites internationally and in the
United States. The Company's system has achieved fetal blood cell
identification in 120 of the 133 samples tested or (90%) of the cases.     
   
  During 1995, the Company used its fetal cell enrichment procedure on 37 blood
samples obtained from mothers in their 11th to 20th week of pregnancy shortly
after they had undergone an invasive prenatal procedure (amniocentesis, CVS or
termination of pregnancy). The Company achieved fetal blood cell identification
in 33 of the 37 samples, or 89% of the samples. The Company planned
international evaluations of its fetal cell enrichment procedure in 1995,
however, the gel in the preformed density gradients was found to be
destabilized at the international evaluation sites. Following further
investigation, the Company determined that the gel in its preformed density
gradient required use within two weeks of its manufacture.     
 
                                       31
<PAGE>
 
   
  In the first half of 1996, utilizing new shipment and handling protocols,
the Company commenced further studies to determine if fetal blood cells could
be enriched and identified in maternal blood samples from mothers in their
11th to 21st week of pregnancy who had not undergone an invasive prenatal
procedure. At the Company's Santa Clara and Israel sites, a total of 20
samples were tested and fetal blood cell identification was achieved in all 20
samples. An independent site in the Netherlands used the fetal cell enrichment
procedure on a group of 20 samples and achieved fetal blood cell
identification in 16 samples, or 80% of the samples. At an independent site in
the United Kingdom 12 samples were processed and in 10 samples, or 83% of the
samples, fetal blood cells were found. As of June 1996, of the 52 samples
processed in 1996, fetal cell identification was achieved in 46 samples, or
88% of the samples.     
   
  In July 1996, the Company conducted an evaluation at its Santa Clara and
Israel sites, and at two independent sites in the Netherlands on 44 samples
from pregnant women in their 9th to 16th week of pregnancy. This evaluation
used fetal cell enrichment procedures which the Company expects to be similar
to those to be submitted to the FDA for review prior to commencing clinical
trials, and utilized a new formulation of the preformed density gradients.
Fetal cell identification was achieved in 41 of these 44 samples, or 93% of
the samples. In three of these samples no fetal cells were found, and in two
samples in which fetal cell identification was achieved only one fetal cell
was found. To date, no application for FDA approval has been submitted with
respect to the fetal cell enrichment system, and there can be no assurance
that FDA approval will be obtained on a timely basis, or at all. See "Risk
Factors--Prenatal Screening System in Early Stage of Development; No Assurance
of Successful Development or Commercialization" and "--Lack of Clinical Data."
    
       
 Clinical/Regulatory Matters
   
  The Company intends to apply for two separate 510(k) clearances for the
fetal cell enrichment and scanning components of its system. The DNA probe
components of the Company's system will require either FDA clearance of a
510(k) with a tier III level of review (the most extensive level of FDA review
of a 510(k), equivalent to the FDA review of a PMA in thoroughness and time)
or FDA approval of a PMA. The Company plans to market its prenatal screening
system internationally upon receipt of required regulatory clearances or
approvals. See "Business--Government Regulation."     
       
 Commercialization Strategy
 
  The Company's prenatal screening system under development is currently
expected to be introduced in Europe in 1997 and subsequently in the United
States and the Pacific Rim, subject to receipt of required clearances or
approvals in such jurisdictions.
 
  The system is being designed to initially screen for chromosomal
abnormalities resulting in conditions such as Down's Syndrome and certain sex
chromosome abnormalities such as Turner Syndrome, Klinefelter Syndrome, Triple
X Syndrome and certain other conditions. These abnormalities account for
approximately 80% of the incidence of all birth defects which result from
chromosome-based genetic disorders. The proprietary prenatal screening system
under development will consist of (i) a prepackaged kit to enrich the
concentration of nucleated fetal red blood cells in the maternal blood sample,
(ii) the Company's instrumentation to automate the identification of fetal
blood cells and the acquisition and presentation of the DNA probe analysis,
and (iii) may or may not include a DNA probe kit that is comprised of DNA
probes available from third parties. The Company's prenatal screening system
under development is being designed to be compatible with its existing
cytogenetic products so that customers could potentially add the prenatal
screening system to their existing installations.
 
FUTURE APPLICATIONS OF THE PRENATAL SCREENING TECHNOLOGY
   
  The Company's prenatal screening system is being designed to accommodate
various chromosome-specific DNA probes, which are currently commercially
available. The Company believes that its fetal cell enrichment technology
developed for prenatal screening could have future applications for cancer
diagnosis via the isolation of tumor cells from peripheral blood and the
genetic analysis of such cells. The Company is also developing proprietary
uses for its fetal cell analysis that may facilitate the early detection of
single gene disorders such as cystic fibrosis, hemophilia, thalassemia,
sickle-cell anemia and Tay-Sachs. The Company intends to pursue these
potential additional applications to leverage its proprietary technology.
Because evaluations of future applications are at an early stage, no assurance
can be given when, if ever, the Company's fetal cell enrichment technology may
facilitate the early detection of single gene disorders or cancers.

CURRENT CYTOGENETIC PRODUCTS
   
  In the United States, approximately 500,000 cytogenetic tests are performed
annually. Cytogenetic testing includes prenatal screening for genetic
disorders using amniotic fluid obtained through amniocentesis and fetal tissue
samples obtained through CVS. Other cytogenetic testing includes screening
tests for diagnosis and prognosis of cancer-related conditions using bone
marrow, blood and tumor tissue samples. The Company currently manufactures,
markets and sells a family of automated instruments for cytogenetic
applications based on the Company's prior generation Cytoscan and GeneVision
product families. The Company's primary cytogenetic products are described
below. The Company currently has an installed base at approximately 500 sites
worldwide in more than 30 countries. The Company's primary cytogenetic
products currently sell for prices ranging from $50,000 to $125,000.     
 
  CytoVision Metaphase Finder. The CytoVision Metaphase Finder consists of a
computer-controlled scanning microscope with a patented autofocus mechanism,
image processing hardware, and pattern recognition software. This product
continuously scans laboratory slides for cells in metaphase and records their
location for future identification and analysis of the cells' chromosomes. The
Metaphase Finder uses the Company's patented autofocus system for continuous
scanning. Cytogenetic analysis involves identifying and inspecting a number of
relatively rare metaphase cells on a slide containing a large number of cells,
a majority of which are not in metaphase. This analysis can take a
cytogeneticist up to one hour per slide if performed manually. The Metaphase
Finder is designed to save laboratory time and cost by automating this labor-
intensive process and can identify the cells in metaphase in approximately ten
minutes. This product is fully compatible with the Company's other cytogenetic
products, which have the potential to save laboratories the expense of using
trained technicians to perform routine tasks prior to actual cytogenetic
analysis.
 
  CytoVision Karyotyper. The CytoVision Karyotyper consists of a computerized
image capture and analysis system which incorporates pattern recognition,
automated chromosome classification algorithms and a high resolution output
device. This product supplants many otherwise manual processes in the
preparation of the data for cytogenetic analysis. The CytoVision Karyotyper
provides automated karyotyping, automatic separation of touching and
overlapping chromosomes, image enhancement features, chromosome rotation and
straightening, image zooming for band analysis, annotation capabilities, and
full screen karyotyping display. This product replaces manual photographing of
cells in metaphase, printing of the photograph, manual cutting out of each
chromosome, identifying the chromosomes, arranging the chromosomes in order,
and pasting them on a sheet of paper. In contrast to the automated process
which takes approximately 10 minutes, this manual process takes approximately
thirty minutes to one hour.
 
  CytoVision Probe. The CytoVision Probe consists of a computerized image
capture and image enhancement system which detects and analyzes fluorescent
DNA probes applied to cell nuclei. These probes are designed to attach
themselves to specific DNA sequences which may indicate genetic disorders.
Fluorescent DNA probes are often very faint when viewed by the human eye
through a microscope. This system enhances images of DNA probes and provides a
range of analytical tools. The Company also offers a comparative genomic
hybridization software upgrade package to the CytoVision Probe to detect
genetic amplifications and deletions in tumor cells. The CytoVision Probe
system is not dependent on specific fluorescent DNA probes and may be used in
conjunction with probes from different manufacturers. In the United States the
CytoVision probe is sold for research purposes only.
   
  All of the products in the CytoVision family, a product generation evolving
from the Company's former Cytoscan and GeneVision product lines, are
compatible and can be integrated into a network with common data management
protocols. In addition to the primary products, the Company also sells a
number of peripherals including a range of high quality printers and image
capture workstations. A typical installation will include a number of
interconnected CytoVision systems.     
 
SALES, DISTRIBUTION AND MARKETING
   
  The Company currently sells its cytogenetic products to government and
private clinical cytogenetic laboratories, research institutions, universities
and pharmaceutical companies. The Company has sold such systems to
approximately 500 sites in more than 30 countries. These customers utilize the
Company's cytogenetic     
 
                                      33
<PAGE>
 
products for prenatal genetic screening as well as for certain cancer screening
applications. The Company's prenatal screening system under development is
being designed to be compatible with its existing cytogenetic products so that
customers could potentially update their new or existing installations to
accommodate its prenatal screening system. If regulatory clearance or approval
is received, the Company initially plans to sell and distribute its prenatal
screening system directly and through its established worldwide network of
distributors and agents through which it sells and distributes its current
products.
   
  In North America, the Company sells its cytogenetic products directly to its
customers. The North American sales team is comprised of six sales and
application support individuals, four of whom are based in Pittsburgh,
Pennsylvania and two in Santa Clara, California. Outside of North America, the
Company sells its products either directly through local agents who are
remunerated on a commission basis or through independent distributors. The
Company manages its international sales and distribution activities from
Applied Imaging International, the Company's wholly-owned subsidiary located in
the United Kingdom. The international sales team is comprised of eight sales
and application support individuals, all of whom are based in the United
Kingdom. The Applied Imaging International Ltd. sales team supports all
distributors and agents upon request. The Company's distributors are located in
Australia, Hong Kong, Japan, Italy and South Korea. In addition, the Company
has agents selling its cytogenetic products in other countries primarily within
Europe, the Middle East and the Pacific Rim. See "Note 11 of Notes to
Consolidated Financial Statements" for financial information concerning foreign
and domestic operations and export sales.     
 
  Because the Company's products are technically sophisticated the Company's
sales staff is supported by scientifically qualified and highly trained product
specialists. The Company offers an annual maintenance program to its customers
through its own support organization. The Company's marketing activities
include telemarketing, product advertising and participation in trade shows and
product seminars.
 
MANUFACTURING
 
  The Company assembles and tests components and subassemblies made by outside
vendors to the Company's specifications and manufactures only when it believes
significant value can be added. The Company's current products are assembled
from a combination of (i) commodity technology components such as computers and
monitors, (ii) custom subassemblies, such as special image capture circuit
boards, and (iii) operating system and application software. Any disruption or
delay in the supply of components or custom subassemblies will have a material
adverse effect on the Company. While the Company typically uses components and
subassemblies which are available from alternate sources, any unanticipated
interruption of the supply of these components or subassemblies could require
the Company to redesign its products.
 
  The Company orders components and subassemblies to forecast and assembles
specific configurations on receipt of firm orders. The Company's research,
investigational and clinical products are subject to regulation by the FDA and
all products are subject to regulation by the U.S. Department of Commerce
export controls, primarily as they relate to the associated computers and
peripherals. The Company has experienced no material difficulties in obtaining
necessary export licenses to date.
 
  The Company plans to initially subcontract third parties to manufacture the
consumable enrichment kit component of its fetal cell screening system under
development and may ultimately manufacture such components on its own. For
clinical trials, the Company will purchase the consumable enrichment kit from a
third party contracted to manufacture the kit. The Company has no experience
manufacturing such components. The Company may encounter difficulties in
scaling up production of the consumable component of its fetal cell screening
system under development or in hiring and training additional personnel to
manufacture its consumable enrichment kit products in commercial quantities.
   
  Under current law, if the Company manufactures finished devices in the United
States, it will be required to comply with the FDA's and the State of
California's current GMP regulations. In addition, the FDA and/or the
California authorities will inspect the Company's manufacturing facilities on a
regular basis to determine such compliance. Failure to comply with applicable
FDA or other regulatory requirements can result in fines, injunctions, civil
penalties, recalls or seizures of products, total or partial suspensions of
production and criminal prosecutions. See "Business--Government Regulation."

RESEARCH AND DEVELOPMENT
 
  The Company's research and development efforts include various research,
product development, clinical evaluation and testing, quality assurance and
process development activities. The current focus of the Company's research
and development efforts is the completion of the development of the Company's
prenatal screening system and particularly the initiation of clinical trials.
The Company is using a consultant to assist in the design the protocols for
the planned clinical trials. The Company's future research and development
efforts are expected to include development of additional applications of the
Company's current cytogenetic products and additional applications of the
fetal cell screening system under development. These potential additional
applications include the use of technology developed for fetal cell analysis
for the diagnosis and screening for certain cancers and certain single gene
disorders. Development of these applications will require substantial
additional funds and will be subject to technological, clinical, regulatory
and other risks associated with new medical technologies. There can be no
assurance that the Company will develop its prenatal screening system or any
other future applications of such technology.
   
  In 1995, the Company entered into a clinical testing agreement with the
Academic Medical Center in Amsterdam to evaluate the Company's technology
relating to fetal cell enrichment from maternal blood and associated
instrumentation. The Company has an unrestricted right to use the data
resulting from the evaluation. In 1995, the Company established a wholly-owned
subsidiary in Israel to conduct further research and development focused on
the enrichment aspect of the prenatal screening system. These research
activities are being primarily funded by a $543,000 research grant issued by
the Binational Research and Development ("BIRD") Organization pursuant to
which repayment is required in the form of royalties from the sale of the
prenatal screening system. In 1996, the Company entered into a collaborative
research agreement with Leiden University in the field of enrichment,
isolation and analysis of fetal cells derived from maternal blood. See
"Business--Patents and Proprietary Rights."     
 
  Research and development expenses were approximately $2.9 million, $2.8
million and $1.8 million for 1995, 1994 and 1993, respectively.
 
PATENTS AND PROPRIETARY RIGHTS
 
  The Company actively seeks, when appropriate, protection for its products
and proprietary information by means of United States and foreign patents and
trademarks. The Company has one issued United States patent relating to its
CytoVision Metaphase Finder and has corresponding issued patents in certain
European countries. In addition, the Company has three United States patents
concerning its technology for enriching the concentration of nucleated fetal
red blood cells from maternal blood samples. Corresponding applications were
filed through the Patent Cooperation Treaty and preserve for the Company the
right to file applications in various countries. The Company relies upon trade
secrets, know-how and contractual arrangements to protect certain of its
proprietary information and products.
 
  The fields of life science instrumentation and genetic screening processes
are covered by many issued patents and patent applications. The Company is not
currently aware of any patents which it may be infringing; however, patent
applications in the United States remain confidential until a patent is
issued, and, therefore, the Company's products could infringe patents to be
issued in the future. If the Company's technology is determined to use
products, processes or other subject matter that is claimed under other
existing U.S. or foreign patents, or if other patents claiming subject matter
utilized by the Company are issued, such companies may bring infringement
actions against the Company. The Company has recently received a letter from
Vysis Corp. informing the Company that its products might fall within the
claims of a United States patent exclusively licensed to Vysis Corp. Vysis
Corp. offered the Company the right to obtain a sublicense to such patent. The
Company does not believe it is necessary to obtain such a sublicense and does
not believe it is infringing the patent. However, there can be no assurance
that the Company will not ultimately be required to seek a license from Vysis
Corp. or any other third party. The Company may be required to obtain licenses
to patents or proprietary rights of others. There can be no assurance that any
such license would be made available or, if available, would be available on
commercially acceptable terms. Failure to obtain a required license could
prevent the Company from commercializing its products resulting in a material
adverse affect on the Company's business, financial condition and results of
operations.
 
                                      35
<PAGE>
 
  The Company generally enters into confidentiality agreements with its
employees and consultants designed to both protect the Company's confidential
information and prevent the disclosure of confidential information of prior
employers and other parties. There can, however, be no assurance that the
Company's trade secrets or proprietary technology will not become known or be
independently developed by competitors in such a manner that the Company has
no practical recourse. Certain employees of and consultants to the Company are
subject to the terms of confidentiality agreements with respect to proprietary
information of their former employers. The failure of these persons to comply
with the terms of their agreements could result in assertion of claims against
the Company and such persons which, if successful, might restrict their roles
within the Company.
 
  In 1996, the Company entered into a collaborative research agreement with
Leiden University ("Leiden") in the field of enrichment, isolation and
analysis of fetal cells derived from maternal blood. Under the terms of the
agreement, the Company has sole ownership of any jointly developed inventions
and has an exclusive license to any issued patents owned solely by Leiden. The
royalty rate for the exclusive license shall not be more than 5% of associated
sales.
   
  The Company also relies upon trademarks to protect certain of its products,
and holds a United States trademark registration for the mark "CYTOSCAN."
Registration for this mark and the mark "CYTOVISION" are held by the Company
in certain foreign jurisdictions.     
   
  The Company also has certain trademark rights in the United States and other
foreign countries. It is possible that third parties may allege superior
rights to one or more of the Company's trademarks, or close variations, for
those countries in which the Company is presently conducting business or may
do so in the future. The Company's rights to use and register its marks in a
given jurisdiction may depend on its rights relative to a third party's rights
as governed by the laws of the pertinent country. Factors utilized to
determine the relevant rights between parties include priority of the use or
registration of the mark, how close the respective marks are in appearance,
sound and/or meaning, as well as the goods to which they are applied. It is
possible that the Company could be prevented from using or registering its
trademarks in certain countries due to a superior third party right.     
 
COMPETITION
   
  The market for the Company's current cytogenetic products is highly
competitive. The Company believes that its primary competitors in this market
include Perceptive Scientific, Inc. (acquired by International Remote Imaging
Systems, Inc.), and Vysis Corp., a biotechnology subsidiary of AMOCO
Technology Company. The principal competitive factors in this market are
product features offered, ease of use, clarity of output, customer service
capabilities, price and installed base. The Company believes it competes
favorably with regard to these factors.     
   
  With respect to its prenatal screening system under development, the Company
is aware of a number of companies that are in the process of developing
genetic screening products based on competing technologies designed to enrich
the concentration of fetal blood cells in maternal blood samples. Many of
these companies have greater research and development, marketing and financial
resources than the Company. These companies include Integrated Genetics, Inc.
(a wholly-owned subsidiary of Genzyme Corp.), CellPro, Incorporated,
Aprogenex, Inc., and Centocor, Inc. Integrated Genetics specializes in
providing genetic testing services. CellPro specializes in cell separation and
gene therapy, Aprogenex specializes in providing DNA probes, and Centocor
specializes in providing monoclonal antibodies.     
 
  The medical diagnostic and biotechnology industries are subject to intense
competition. The Company's fetal cell screening system under development, if
commercially marketed, will also be subject to intense competition from
existing procedures such as maternal AFP, triple test, CVS and amniocentesis.
There can be no assurance that the Company's fetal cell screening system under
development will replace any existing procedures. The Company expects the
principal competitive factors in the fetal cell screening market to be
reliability, accuracy, range of disorders detected, risk to the fetus and the
price of testing.
 
  Many of the Company's competitors have greater financial and technical
resources and production and marketing capabilities than the Company. There
can be no assurance that these competitors will not succeed in
 
                                      36
<PAGE>
 
developing technologies and products that are more effective, easier to use or
less expensive than those which are currently offered or being developed by
the Company or that would render the Company's technology and products
obsolete and noncompetitive. In addition, many of the Company's competitors
have significantly greater experience than the Company in conducting clinical
investigations of new diagnostic products and in obtaining FDA and other
regulatory clearances and approvals of products. Accordingly, the Company's
competitors may succeed in developing and obtaining regulatory approvals for
such products more rapidly than the Company.
 
GOVERNMENT REGULATION
 
  The preclinical and clinical testing, manufacturing, labeling, distribution,
sales, marketing, advertising and promotion of the Company's research,
investigational and clinical diagnostic products are subject to extensive and
rigorous government regulation in the United States and in other countries. In
the United States and certain other countries, the process of obtaining and
maintaining required regulatory clearances or approvals is lengthy, expensive
and uncertain. The Company believes that its future success will be
significantly dependent upon commercial sales of its prenatal screening system
under development. The Company will not be able to market this system for
clinical diagnostic use in the United States unless and until the Company
obtains clearance or approval from the FDA and will not be able to market such
system overseas until it meets the safety and quality regulations of each
foreign jurisdiction in which the Company, its agents or distributors seeks to
sell such system. In the United States, the Company's products are also
subject to regulation by state authorities. The State of California's
requirements in this area, in particular, are extensive, and require
registration with the state and compliance with GMP regulations during
clinical trials.
 
  Noncompliance with applicable FDA requirements can result in, among other
things, fines, injunctions, civil penalties, recall or seizure of products,
total or partial suspension of production, distribution, sales, and marketing,
refusal of the government to grant approval of a PMA or clearance of a 510(k),
withdrawal of marketing approvals or clearances, a recommendation by the FDA
that the manufacturer or distributor not be permitted to enter into government
contracts, and criminal prosecution. In certain circumstances, the FDA also
has the authority to order the manufacturer or distributor of a device to
repair, replace or refund of the cost of the device. Failure to comply with
regulatory requirements in the United States or abroad could have a material
adverse effect on the company's business, financial condition, and results of
operations.
 
  With exceptions for certain medical devices first marketed before May 28,
1976, prior to their commercial sale in the United States, medical devices
must be cleared or approved by the FDA or be exempted from the requirement of
FDA clearance or approval. In general, the regulatory process can be lengthy,
expensive and uncertain, and securing FDA clearances or approvals may require
the submission of extensive clinical data together with other supporting
information to the FDA.
 
  In the United States, medical devices are classified as 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 FDA-mandated
current good manufacturing practices ("GMP") requirements), and Class II
devices are subject to general controls and 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 ensure their safety and effectiveness (e.g.,
life sustaining, life supporting and implantable devices) and also include
most devices that were not on the market before May 28, 1976 ("new medical
devices") and for which the FDA has not made a finding of "substantial
equivalence" based on a 510(k). Class III devices usually require clinical
testing and FDA approval prior to marketing and distribution.
 
  Before a new medical device can be introduced into the market, the
manufacturer must obtain FDA clearance of a 510(k) or approval of a PMA,
unless the device is exempt from the requirement of such clearance or
approval. A 510(k) clearance will be granted if the submitted information
establishes that the device is substantially equivalent to a legally marketed
Class I or II medical device or to a legally marketed Class III device that
does not itself require an approved PMA prior to marketing ("predicate
device"). A 510(k) must
 
                                      37
<PAGE>
 
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. Such studies can take years to complete, analyze, and
prepare for submission to the FDA. Commercial distribution of a device for
which a 510(k) is required may begin only after the FDA issues an order
finding the device to be "substantially equivalent" to a predicate device. The
FDA has recently been requiring a more rigorous demonstration of substantial
equivalence than in the past and is more likely to require the submission of
data from one or more human clinical trials. A 510(k) for a device
incorporating new technology may be given a tier III level of review, which is
equivalent to the review given to a PMA in thoroughness and time. The FDA has
no specific time limitation by which it must respond to a 510(k). It generally
takes from five to twelve months from the date of submission to obtain 510(k)
clearance from the FDA, but it may take longer and 510(k) clearance may never
be obtained. The FDA may determine that a device is not "substantially
equivalent" to a predicate device, or that additional information is needed
before a substantial equivalence determination can be made.
   
  A PMA must be filed with and approved by the FDA before marketing may begin
if a device is not found by the FDA to be substantially equivalent to a
predicate device. A PMA must be supported by valid scientific evidence that
typically includes extensive data, including data from preclinical testing and
human clinical trials to demonstrate the safety and effectiveness of the
device. The FDA often requires the performance of at least two independent,
statistically significant human clinical trials that must demonstrate the
safety and effectiveness of the device in order to obtain FDA approval of the
PMA. If human clinical trials of a device are required and the device presents
a "significant risk," the sponsor of the trial (usually the manufacturer or
the distributor of the device) is required to file an investigational device
exemption ("IDE") application with the FDA prior to commencing human clinical
trials. The IDE application must be supported by data, typically including the
results of animal and laboratory testing. If the IDE application is approved
by the FDA (or the FDA does not notify the sponsor 30 days after receipt of
the application that the trials may not begin) and the study protocol is
approved by one or more appropriate institutional review boards ("IRBs"),
human clinical trials may begin at a specific number of investigational sites
with a specific number of patients, as approved by the FDA. If the device
presents a "nonsignificant risk" to the patient, a sponsor may begin the human
clinical trials after obtaining approval of the study protocol by one or more
appropriate IRBs, but not by the FDA unless the FDA notifies the sponsor that
an IDE application is required. Sponsors of human clinical trials are
permitted under the FDA's regulations to sell those devices distributed in the
course of the trials provided the price charged is not larger than that
necessary to recover the costs of manufacture, research, development and
handling. An IDE supplement must be submitted to, and approved by, the FDA (or
the FDA does not notify the sponsor 30 days after receipt of the supplement
that the change may not be implemented) before a sponsor or an investigator
may make a change to the investigational plan that may affect its scientific
soundness or the rights, safety or welfare of human subjects. The FDA has the
authority to re-evaluate, alter, suspend or terminate clinical testing based
on its assessment of data collected throughout the trials.     
 
  The PMA must also contain the results of all relevant bench tests,
laboratory and animal studies, 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 and promotional labeling. Upon submission of a PMA, the FDA
makes a threshold determination regarding whether the application is
sufficiently complete to permit filing for a substantive review. If the FDA
determines that the PMA application is sufficiently complete to permit such
review, the FDA will accept the application for filing. Once the submission is
accepted for filing, the FDA begins an in-depth review of the PMA. An FDA
review of a PMA generally takes one to two years from the date the PMA is
accepted for filing, but may take significantly longer if the FDA requests
additional information and any major amendments to the PMA are filed. The
review time is often significantly extended by the FDA's asking for more
information or clarification of information already provided in the
submission. During the review period, an advisory committee, typically a panel
of clinicians, will likely be convened to review and evaluate the application
and provide recommendations to the FDA regarding whether the PMA should be
approved. The FDA is not bound by the recommendations of the advisory panel.
Toward the end of the PMA review process, the FDA generally will conduct an
inspection of the manufacturer's facilities to ensure that the facilities are
in compliance with the applicable GMP requirements.
 
                                      38

  If the FDA's evaluations of both the PMA and the manufacturing facilities
are favorable, the FDA will issue either an approval letter (order) or an
"approvable letter" containing a number of conditions that must be met in
order to secure approval of a PMA. When and if those conditions have been
fulfilled to the satisfaction of the FDA, the agency will issue an order
approving the PMA, authorizing commercial marketing of the device for certain
indications. If the FDA's evaluation of the PMA or manufacturing facilities is
not favorable, the FDA will deny approval of the PMA or issue a "not
approvable letter." The FDA may also determine that additional preclinical
testing or human clinical trials are necessary, in which case approval of the
PMA could be delayed for several years while additional testing or trials are
conducted and submitted in an amendment to the PMA. The PMA process can be
expensive, uncertain and length, and a number of devices for which FDA
approval has been sought by other companies have never been approved for
marketing.
   
  Under the FDA's regulatory scheme, the decision whether to seek 510(k)
clearance for a changed or modified device is left to the manufacturer in the
first instance. The Company to date has not sought 510(k) clearance for its
CytoVision products on the basis of the Company's conclusion, reflected in the
Company's scientific report addressing this matter, that CytoVision is a new
model of Cytoscan and there have not been any changes or modifications in
design, components, method of manufacture, or intended use, which could
significantly affect the safety or effectiveness of the original device. There
can be no assurance that the FDA will agree with the Company's decision not to
seek 510(k) clearance for CytoVision, and that it will not require the Company
to cease sales and distribution and seek 510(k) clearance for the CytoVision
system, or that such clearance, if required, will be obtained in a timely
manner if at all.     
   
  The Company intends to submit a protocol for clinical trials of the DNA
probe component of its prenatal testing system to the FDA before the end of
1996 and to initiate a multisite United States and international clinical
trial of the DNA probe component of its prenatal testing system to detect
chromosomal disorders in isolated fetal cells during the first half of 1997.
There can be no assurance regarding the timing or nature of the FDA response
regarding the DNA probe related protocol or the timing for the commencement of
clinical trials. There can be no assurance that 510(k) clearance for any
portion of the prenatal screening system under development or any other future
product or modification of an existing product will be granted or that the
clearance process will not be unduly lengthy and subjected to a thorough
internal review equivalent to that ordinarily reserved for devices requiring
premarket approval by the FDA. If substantial equivalence cannot be
established or if the FDA determines that the device or the particular
intended use for the device falls within its guideline the FDA may require a
more rigorous review which the FDA has stated is possible for the Company's
prenatal screening system under development, the FDA will require that the
Company submit a PMA that must be reviewed and approved by the FDA prior to
sales, distribution and marketing of these products in the United States. The
PMA process is significantly more complex, expensive and time consuming than
the 510(k) process. While the Company has made determinations regarding the
appropriate form of approval, if any, required for its products, there can be
no assurance that such determinations are correct, that the FDA will concur
with such determinations or that such determinations may not be altered due to
new interpretations or new data that may become available or changes in the
FDA's policies. Currently, the DNA probes that the Company intends to purchase
from third parties to incorporate into its prenatal screening technology are
sold on a research basis without FDA approval for commercial sale. The FDA
requires DNA probes to have 510(k) clearance or PMA approval for commercial
sale for clinical diagnostic use, which could cause the price of DNA probes to
increase, making the Company's prenatal screening system less price
competitive compared to existing prenatal genetic test procedures.     
   
  Export sales of investigational devices that are subject to PMA or
investigational device exemption application requirements and have not
received FDA marketing approval generally may be subject to FDA export permit
requirements depending upon, among other things, the purpose of the export
(investigational or commercial), the country to which the device is intended
for export, and on whether the device has valid marketing authorization in a
country listed in the FDA Export Reform and Enhancement Act of 1996. In order
to obtain such a permit, when one is required, the Company must provide the
FDA with documentation from the medical device regulatory authority of the
country in which the purchaser is located, stating that the device has the
approval of the country. In addition, the FDA must find that exportation of
the device is not contrary to the public health and safety of the country in
order for the Company to obtain the permit.     
 
                                      39
<PAGE>
 
  In addition to domestic regulation of medical devices, the Company's current
products and its products under development are subject to corresponding
regulations governing safety processes, manufacturing processes and quality in
foreign jurisdictions in which it operates or such products are sold. The sale
of the fetal cell screening system under development may be materially
affected by the policies of regulatory bodies or the domestic politics of the
countries involved. There can be no assurance that an early prenatal screening
test for genetic disorders will not be prohibited or restricted in some
jurisdictions. In addition, FDA export permits may be required for shipment of
the Company's fetal cell screening system under development to certain foreign
countries. Failure to comply with applicable regulatory requirements can,
among other consequences, result in fines, injunctions, civil penalties,
suspensions or loss of regulatory approvals, product recalls, seizure of
products, operating restrictions and criminal prosecution. In addition, future
governmental regulations may be established that could prevent or delay
regulatory approval of the Company's products. The regulation of medical
devices in a number of such jurisdictions continues to develop and there can
be no assurance that new laws or regulations will not have a material adverse
effect on the Company's business. The European Community and its member
countries currently are imposing more substantial regulation on in vitro
diagnostic devices and equipment-like medical devices, and such regulation may
affect the Company's current products and products under development.
 
  Delays in receipt of clearances or approvals to market its products, failure
to receive these clearances or approvals, the loss of previously received
clearances or approvals or the determination that 510(k) clearance, pre-market
approval or other approval is required for a product being marketed without
such clearance or approval could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
  In addition, the Company's current products and the fetal cell screening
system under development could be affected by the Clinical Laboratory
Improvement Amendments of 1988 ("CLIA"), which are intended to ensure the
quality and reliability of medical testing in the United States regardless of
where tests are performed. CLIA or regulations thereunder could negatively
affect the Company's ability to market its products.
   
  The Company is also required to register as a medical device manufacturer
with the FDA and state agencies, such as the California Department of Health
Services ("CDHS") and to list its products semi-annually. Marketed devices are
subject to pervasive and continuing regulatory oversight by the FDA and other
agencies, including record-keeping requirements and reporting of adverse
experiences with the use of the device. Device manufacturers are required to
register their establishments and list their devices with the FDA and certain
state agencies and are subject to periodic inspections by the FDA and CDHS.
The Federal Food, Drug and Cosmetic Act requires that medical devices be
manufactured in accordance with the FDA's GMP regulation and documented. This
regulation requires, among other things, that (i) the manufacturing process be
regulated and controlled by the use of written procedures, and (ii) the
ability to produce devices which meet the manufacturer's specifications be
validated by extensive and detailed testing of every aspect of the process.
The regulation also requires investigation of any deficiencies in the
manufacturing process or in the products produced and detailed record keeping.
Manufacturing facilities are subject to FDA inspection on a periodic basis to
monitor compliance with GMP requirements. If violations if the applicable
regulations are noted during FDA inspections of manufacturing facilities, the
FDA can prohibit further manufacturing, distribution and sale of the devices
until the violations are cured. The FDA has proposed changes to the GMP
regulation that would, among other things, subject manufacturers of components
to GMP requirements in certain circumstances, and require pre-production
design controls and maintenance of service records. If finalized these changes
would likely increase the cost of complying with GMP requirements. Other
applicable requirements include the FDA's medical device (manufacturer)
reporting regulation, which requires that the device manufacturer provide
information to the FDA on deaths or serious injuries alleged to have been
associated with the use of its marketed devices, as well as product
malfunctions that would likely cause or contribute to a death or serious
injury if the malfunction were to recur.     
 
  Labeling, advertising and promotional activities for investigational and
marketed devices are subject to scrutiny by the FDA and, in certain instances,
by the Federal Trade Commission. The FDA enforces statutory prohibitions
against promoting or marketing products for unapproved uses.
 
                                      40
<PAGE>
 
  The Company is also subject to other federal, state, local and foreign laws,
regulations and recommendations relating to safe working conditions,
laboratory and manufacturing practices, including but not limited to the
requirements of the CLIA. The extent of government regulation that might
result from any future legislation or administrative action cannot be
accurately predicted. Failure to comply with any federal or state regulatory
requirements could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
THIRD-PARTY REIMBURSEMENT AND HEALTH CARE REFORM
 
  In the United States, the Company's products are purchased primarily by
medical institutions which then bill various third-party payors, such as
Medicaid, other government programs and private insurance plans, for the
health care services provided to their patients. Third-party payors may deny
reimbursement if they determine that the device used in a treatment was
unnecessary, inappropriate, experimental or investigational, used for a non-
approved indication, or not cost-effective and typically do not reimburse for
devices used for research and investigational purposes. Accordingly,
physicians must determine that the clinical benefits of genetic screening
procedures justify additional cost. The market for the Company's current
cytogenetic products could be adversely affected by changes in governmental
and private third-party payors' policies and the market for the Company's
fetal cell screening system under development could be materially adversely
effected by the failure of governmental and third-party payors adopting
policies to reimburse health care providers for the use of the Company's fetal
cell screening system under development. The unavailability of third-party
coverage or the inadequacy of the reimbursement for medical procedures using
the Company's products would adversely affect the Company's business,
financial condition and results of operations. In both the United States and
internationally, third-party payors are increasingly challenging the prices
charged for medical products and services. There can be no assurance that
reimbursement for the procedures using the Company's products will be
available or, if currently available, will continue to be available, or that
future reimbursement policies of payors will not adversely affect the
Company's ability to sell its products on a profitable basis. In addition,
there can be no assurance that third-party reimbursement will be available for
diagnostic procedures based on the Company's fetal cell screening system under
development.
 
  The levels of revenues and profitability of medical device companies may be
affected by the continuing efforts of governmental and third-party payors to
contain or reduce the costs of health care through various means. In the
United States, there have been, and the Company expects that there will
continue to be, a number of federal and state proposals to implement
government regulation of health care costs. It is uncertain what legislative
proposals will be adopted or what actions federal, state or private payers for
health care goods and services may take in response to any health care reform
proposals or legislation. The Company cannot predict the effect health care
reforms may have on its business, and no assurance can be given that any such
reforms will not have a material adverse effect on the Company's business,
financial condition and results of operations. Further, to the extent that
such proposals or reforms have a material adverse effect on the business,
financial condition and profitability of the clinical and research
laboratories, hospitals and other institutions that comprise the Company's
customer base, the Company's business, financial condition and results of
operations could be adversely affected.
 
PRODUCT LIABILITY AND INSURANCE
 
  The Company's business may involve the risk of product liability claims,
including those relating to inaccurate results from its screening products.
Although the Company has not experienced any product liability claims to date,
any such claims could have a material adverse impact on the Company. The
Company maintains product liability insurance at coverage levels which it
deems commercially reasonable; however, there can be no assurance that product
liability or other claims will not exceed such insurance coverage limits or
that such insurance will continue to be available on commercially acceptable
terms, or at all. The Company intends to evaluate, depending on the
circumstances that exist at the time, whether or not to obtain any additional
product liability insurance coverage prior to the time that the Company
engages in any extensive marketing of its fetal cell screening system under
development. Even if the Company obtains additional product liability
insurance,
 
                                      41
<PAGE>
 
there can be no assurance that it would prove adequate or that a product
liability claim, insured or uninsured, would not have a material adverse
effect on the Company's business, financial condition and results of
operations. Even if a product liability claim is not successful, the time and
expense of defending against such a claim may adversely affect the Company's
business, financial condition and results of operations.
 
EMPLOYEES
   
  As of June 30, 1996, the Company had 85 employees, of whom 32 were involved
in research and development, 9 in manufacturing and manufacturing engineering,
30 in sales, marketing and customer service and 14 in finance and
administration. As of June 30, 1996, 39 of the employees were based in the
United Kingdom, 41 in the United States, 4 in Israel, and 1 in France. A total
of 12 employees hold Ph.Ds, and 2 employees are M.D.s. The Company's employees
include trained cytogeneticists to specify, support and sell its product
range. The Company believes that its relationship with its employees is good.
    
FACILITIES
   
  In the United States, Applied Imaging leases an approximately 14,000 square
foot facility in Santa Clara, California, under a lease which terminates in
April 1997. The Company also leases an approximately 2,700 square foot
facility in Pittsburgh, Pennsylvania, under a lease which terminates in July
1999. In the United Kingdom, Applied Imaging International Ltd. leases an
approximately 10,000 square foot facility in Sunderland, which lease
terminates in June 1998. In Israel, Applied Imaging Ltd. leases an
approximately 1,500 square foot facility near Tel Aviv under a short-term
lease arrangement. The Company believes that its facilities are adequate to
meet its requirements until at least through mid-1997.

BOARD COMPOSITION
 
  The Company currently has authorized eight directors. In accordance with the
terms of the Company's Restated Articles of Incorporation, effective upon the
closing of this offering, the terms of office of the Board of Directors will
be divided into three classes; Class I, whose term will expire at the annual
meeting of shareholders to be held in 1997; Class II, whose term will expire
at the annual meeting of shareholders to be held in 1998; and Class III, whose
term will expire at the annual meeting of shareholders to be held in 1999. The
Class I directors are Michael S. Elias, Thomas C. McConnell and Gilbert J. R.
McCabe, the Class II directors are John F. Blakemore, Jr., Robert C. Miller
and G. Kirk Raab, and the Class III directors are Abraham I. Coriat and Andre
F. Marion. At each annual meeting of shareholders after the initial
classification, the successors to directors whose term will then expire will
be elected to serve from the time of election and qualification until the
third annual meeting following election. In addition, the Company's Restated
Articles of Incorporation provide that the authorized number of directors may
be changed only by resolution of the Board of Directors. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of one-third of the directors. This classification of the Board
of Directors may have the effect of delaying or preventing changes in control
or management of the Company.
 
  Each officer is elected by and serves at the discretion of the Board of
Directors. Each of the Company's officers and directors, other than
nonemployee directors, devote substantially full time to the affairs of the
Company. The Company's nonemployee directors devote such time to the affairs
of the Company as is necessary to discharge their duties. There are no family
relationships among any of the directors, officers or key employees of the
Company.

  The Audit Committee of the Board of Directors reviews the internal
accounting procedures of the Company and consults with and reviews the
services provided by the Company's independent accountants. The members of the
Audit Committee are Messrs. John F. Blakemore, Jr., Michael S. Elias and
Abraham I. Coriat. The Compensation Committee of the Board of Directors
reviews and recommends to the Board the compensation and benefits of all
officers of the Company and establishes and reviews general policies relating
to compensation and benefits of employees of the Company. The members of the
Compensation Committee are Messrs. Thomas C. McConnell, Gilbert J. R. McCabe
and John F. Blakemore.
 
DIRECTOR COMPENSATION
   
  Gilbert J. R. McCabe, G. Kirk Raab, John F. Blakemore, and Andre F. Marion
receive $800 per meeting attended, and all Directors receive reimbursement of

Directors. Under the Company's Director Option Plan, each director who is not
also an employee or consultant of the Company (an "Outside Director") will
automatically receive an option to purchase 5,000 shares of Common Stock upon
joining the Board of Directors or, in the case of current Outside Directors,
upon re-election to the Board of Directors at the first annual meeting of the
shareholders following this offering. Thereafter, each Outside Director who
has served on the Board of Directors for at least six months shall receive an
option to acquire 5,000 shares of Common Stock on the date of each of the
Company's annual meetings of shareholders, provided such Outside Director is
re-elected. Each option granted under the Director Option Plan will become
exercisable ratably over a four-year period.

shares available for grant under the 1988 Option Plan subject to approval of
the stockholders within twelve months of the approval by the Board of
Directors. The purposes of the 1988 Option Plan are to attract and retain
qualified personnel, to provide additional incentives to employees, officers
and consultants of the Company and to promote the success of the Company's
business. Pursuant to the 1988 Option Plan, the Company may grant options
which qualify as incentive stock options under Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), to employees (including
officers and directors who are employees) and nonqualified stock options to
employees, officers, directors and consultants.     
   
  The Compensation Committee is authorized to administer the 1988 Option Plan,
including the selection of the employees, directors and consultants of the
Company to whom stock options may be granted and the interpretation and
adoption of rules for the operation of the 1988 Option Plan. Options granted
under the 1988 Option Plan generally become exercisable at the rate of 25% of
the shares one year from the grant date and approximately 25% of the shares at
the end of each one-year period thereafter such that the option is fully
exercisable four years from the grant date. However, the vesting schedule is
subject to modification by the Board of Directors. The maximum term for
options granted under the 1988 Option Plan is ten years, except that if at the
time of the grant the optionee possesses more than 10% of the combined voting
power of the Company or is an affiliate (as defined in the Code) of the
Company (a "10% Stockholder"), the maximum term of an option is five years.
The exercise price of incentive stock options granted to a 10% Stockholder
must be at least 110% of the fair market value of the stock subject to the
option on the date of grant. The exercise price of nonqualified stock options
granted under the 1988 Option Plan must be at least 85% of the fair market
value of the stock subject to the option on the date of grant. Payment of the
exercise price may be made by cash, promissory note or other consideration as
determined by the Board of Directors. The 1988 Option Plan may be amended at
any time by the Board of Directors, although certain amendments would require
stockholder approval. The 1988 Option Plan will terminate in 1998, unless
earlier terminated by the Board of Directors.     
   
  1994 Director Option Plan. The Company's 1994 Director Option Plan (the
"Director Plan") was adopted by the Board of Directors and approved by the
stockholders in February 1994. As of March 31, 1996, 50,000 shares of Common
Stock were reserved for issuance under the Director Plan. In June 1996, the
Board of Directors approved an increase of 70,000 shares of Common Stock
available for grant under the Director Plan subject to approval by the
stockholders within twelve months of Board of Directors approval of such
increase. Each nonemployee director who becomes a director after the date of
this Prospectus will be automatically granted a nonstatutory option to
purchase 5,000 shares of Common Stock on the date on which such person first
becomes a director or in the case of current nonemployee directors, upon re-
election to the Board of Directors at the first annual meeting of the
stockholders following this offering. Thereafter, each nonemployee director
who has served on the Board of Directors for at least six months shall receive
an option to acquire 5,000 shares of Common Stock on the date of each of the
Company's annual meetings of the shareholders, provided such nonemployee
director is re-elected. Each option granted under the Director Plan will
become exercisable ratably over a four-year period. In the event of a change
in control of the Company, including a merger or sale of substantially all of
the Company's assets, outstanding options must be assumed by any successor
corporation, or they will become fully vested and exercisable. The exercise
price of all options granted under the Director Plan after the date of this
Prospectus will be equal to the fair market value of the Common Stock on the
date of grant. Each option grant under the Director Plan will vest on a
cumulative yearly basis over a four-year period. All such options will expire
ten years from the date of grant unless terminated sooner pursuant to the
provisions of the Director Plan. The Board of Directors may amend the Director
Plan at any time. The Director Plan will terminate in February 2004. No
options have been granted under the Director Plan to date.

  Employee Stock Purchase Plan. The Company's Employee Stock Purchase Plan
(the "Purchase Plan") was adopted by the Company's Board of Directors in June
1996 and it is anticipated that the Purchase Plan will be approved by the
stockholders prior to the closing of this offering. The Purchase Plan is
intended to qualify under Section 423 of the Code. The Company has reserved
200,000 shares of Common Stock for issuance under the Purchase Plan. Under the
Purchase Plan, an eligible employee may purchase shares of Common Stock from
the Company through payroll deductions of up to 10% of his or her
compensation, at a price per share equal to 85% of the lower of (i) the fair
market value of the Company's Common Stock on the first day of an offering
period under the Purchase Plan or (ii) the fair market value of the Common
Stock on the last day of an offering period. Except for the first offering
period, each offering period will last for six months and will commence the
first day on which the national stock exchanges and The Nasdaq Stock Market
are open for trading, on or after May 1 and November 1 of each year. The first
offering period will begin upon the effective date of this offering and will
end on April 30, 1997. Any employee who is customarily employed for at least
20 hours per week and more than five months per calendar year, and who has
been so employed for at least three consecutive months on or before the
commencement date of an offering period is eligible to participate in the
Purchase Plan. No shares have been purchased under the Purchase Plan to date.
    
EMPLOYEE RETIREMENT PLANS
   
  United States. In January 1994, the Company implemented a Retirement Savings
and Investment Plan that is intended to qualify under Section 401(k) of the
Code (the "401(k) Plan") covering all of the Company's United States based
employees who have completed three months of service and have attained age 21.
An employee may elect to defer, in the form of contributions to the 401(k)
Plan on his or her behalf, up to 15% of the total compensation that would
otherwise be paid to the employee, not to exceed the amount allowed by
applicable Internal Revenue Service guidelines. The Company will match 100% of
amounts deferred by the employee participants up to 3% of such employee's
total compensation and such matching amounts vest over a three year period
from the initial participation date. During 1993, 1994 and 1995, the Company
made contributions to the 401(k) Plan totalling approximately $18,000, $38,000
and $51,000, respectively. Contributions by employees or by the Company to the
401(k) Plan, and income earned on plan contributions, are not taxable to
employees until withdrawn from the 401(k) Plan. Contributions by the Company
are deductible by the Company when made.     
 
  United Kingdom. The Company's United Kingdom based employees are covered by
retirement savings plans (the "International Retirement Plans"). Under such
plans, an employee may elect to make contributions of 3.5% of such employee's
earnings. Amounts contributed by the Company range from 5.5% to 10.5% of such
employee's earnings. During 1993, 1994 and 1995, the Company paid or accrued
contributions to the International Retirement Plans totaling $83,000, $60,000
and $43,000, respectively. Contributions by employees or by the Company to the
International Retirement Plans, and income earned on plan contributions, are
not taxable to employees until withdrawn from such plans. Contributions by the
Company are deductible by the Company when made.

                         DESCRIPTION OF CAPITAL STOCK
   
  The authorized capital stock of the Company will consist of 20,000,000
shares of Common Stock and 6,000,000 shares of Preferred Stock after giving
effect to the conversion of all outstanding shares of Preferred Stock into
Common Stock and the restatement of the Company's Articles of Incorporation
upon the closing of this offering.     
 
  The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Company's Restated
Articles of Incorporation which are included as an exhibit to the Registration
Statement of which this Prospectus is a part, and by the provisions of
applicable law.
 
COMMON STOCK
   
  As of June 30, 1996, there were 5,136,064 shares of Common Stock outstanding
which were held of record by 137 stockholders, on a pro forma basis to reflect
the conversion of all outstanding shares of Preferred Stock which will occur
upon the closing of this offering.     
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the shareholders. Subject to preferences that may
be applicable to any outstanding Preferred Stock, the holders of Common Stock
are entitled to receive ratably such dividends, if any, as may be declared
from time to time by the Board of Directors out of funds legally available for
that purpose. See "Dividend Policy." In the event of a liquidation,
dissolution or winding up of the Company, the holders of Common Stock are
entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior distribution rights of Preferred Stock, if any,
then outstanding. The Common Stock has no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions
applicable to the Common Stock. The holders of 15,000 shares of Common Stock
issued pursuant to the Series H Preferred Stock Financing or their transferees
are entitled to certain rights with respect to the registration of such shares
under the Securities Act. All outstanding shares of Common Stock are fully
paid and non-assessable, and the shares of Common Stock to be issued upon the
closing of this offering will be fully paid and non-assessable.
 
PREFERRED STOCK
   
  Effective upon the closing of this offering, the Company will be authorized
to issue 6,000,000 shares of undesignated Preferred Stock, none of which will
be outstanding upon the closing of this offering. The Board of Directors will
have the authority, without further action by the shareholders, to issue the
undesignated Preferred Stock in one or more series, to fix the rights,
preferences, privileges and restrictions granted to or imposed upon any wholly
unissued shares of undesignated Preferred Stock and to fix the number of
shares constituting any series and the designation of such series.     
 
  The issuance of Preferred Stock may have the effect of delaying, deferring
or preventing a change in control of the Company without further action by the
shareholders, may discourage bids for the Company's Common Stock at a premium
over the market price of the Common Stock and may adversely affect the market
price of and the voting and other rights of the holders of Common Stock. At
present, the Company has no plans to issue any of the Preferred Stock.
 
WARRANTS
   
  As of June 30, 1996, the Company had outstanding a warrant to purchase
140,000 shares of Common Stock at $4.25 per share expiring in July 2000 and
warrants to purchase 368,734 shares of Common Stock at $5.25 per share
expiring in July 1998. The shares underlying these warrants are entitled to
registration rights. See "Description of Capital Stock--Registration Rights of
Certain Holders."     
 
 
                                      54
<PAGE>
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
   
  The holders of 3,596,940 shares of Common Stock and warrants to purchase
508,734 shares of Common Stock (the "Registrable Securities") or their
transferees are entitled to certain rights with respect to the registration of
such shares under the Securities Act. These rights are provided under the
terms of an agreement between the Company and the holders of Registrable
Securities. Subject to certain limitations in the agreement, the holders of at
least a majority of the Registrable Securities may require, on two occasions
beginning six months after the date of this Prospectus, that the Company use
its best efforts to register the Registrable Securities for public resale. If
the Company registers any of its Common Stock either for its own account or
for the account of other security holders, the holders of Registrable
Securities are entitled to include their shares of Common Stock in the
registration, subject to the ability of the underwriters to limit the number
of shares included in the offering. The holders of at least five percent of
the Registrable Securities may also require the Company to register all or a
portion of their Registrable Securities on Form S-3 when use of such form
becomes available to the Company, provided, among other limitations, that the
proposed aggregate selling price (net of any underwriters' discounts or
commissions) is at least $1 million. All registration expenses must be borne
by the Company and all selling expenses relating to Registrable Securities
must be borne by the holders of the securities being registered.     
   
CERTAIN PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS
       
  Certain provisions of the Company's Restated Certificate of Incorporation
and Bylaws may have the effect of preventing, discouraging or delaying a
change in the control of the Company and may maintain the incumbency of the
Board of Directors and management. The authorization of undesignated Preferred
Stock makes it possible for the Board of Directors to issue Preferred Stock
with voting or other rights or preferences that could impede the success of
any attempt to change control of the Company. In addition, the Company's
Bylaws limit the ability of stockholders of the Company to raise matters at a
meeting of stockholders without giving advance notice.     
   
  The Restated Certificate of Incorporation provides that stockholder action
can be taken only at an annual or special meeting of stockholders and cannot
be taken by written consent in lieu of a meeting. The Certificate of
Incorporation and the Bylaws provide that, except as otherwise required by
law, special meetings of the stockholders can only be called pursuant to a
resolution adopted by a majority of the Board of Directors, by the Chief
Executive Officer of the Company, or by stockholders holding shares in the
aggregate entitled to cast not less than 10% of the votes at that meeting.
       
  The Bylaws establish an advance notice procedure for stockholder proposal to
be brought before an annual meeting of stockholders of the Company, including
proposed nominations of persons for election to the Board. Stockholders at an
annual meeting may only consider proposals or nominations specified in the
notice of meeting or brought before the meeting by or at the direction of the
Board or by a stockholder who was a stockholder who was a stockholder of
record on the record date for the meeting, who is entitled to vote at the
meeting and who has given to the Company's Secretary timely written notice, in
proper form, of the stockholder's intention to bring that business before the
meeting. Although the Bylaws do not give the Board the power to approve or
disapprove stockholder nominations of candidates or proposals regarding other
business to be conducted at a special or annual meeting, the Bylaws may have
the effect of precluding the conduct of certain business at a meeting if the
proper procedures are not followed or may discourage or defer a potential
acquiror from conducting a solicitation of proxies to elect its own slate of
directors or otherwise attempting to obtain control of the Company.     
   
CERTAIN PROVISIONS OF DELAWARE LAW     
   
  Following the consummation of the offering, the Company will be subject to
the "Business Combination" provisions of the Delaware General Corporation Law.
In general, such provisions prohibit a publicly held Delaware corporation form
engaging in various "business combination" transactions with any "interested
stockholder" for a period of three year after the date of the transaction
which the person became an "interested stockholder," unless (i) the
transaction is approved by the Board of Directors prior to the date the
interested     
 
                                      55
<PAGE>
 
   
stockholder obtained such status, (ii) upon consummation of the transaction
which resulted in the stockholder becoming an "interested stockholder," the
"interested stockholder" owned at least 85% of the voting stock of the
corporation outstanding those shares owned by (a) persons who are directors
and also officers an (b) employee stock plans in which employee participants
do not have the right to determine confidentially whether shares held subject
to the plan will be tendered in a tender or exchange offer, or (iii) on or
subsequent to such date the "business combination" is approved by the board of
directors and authorized at an annual or special meeting of stockholders by
the affirmative vote of at least 66 2/3% of the outstanding voting stock which
is not owned by the "interested stockholder." A "business combination" is
defined to include mergers, asset sales and other transactions resulting in a
financial benefit to a stockholder. In general, an "interested stockholder" is
a person who, together with affiliates and associates, owns (or within three
years, did own) 15% or more of a corporation's voting stock. The statute could
prohibit or delay mergers or other takeover or change in control attempts with
respect to the Company and, accordingly, may discourage attempts to acquire
the Company.

  The transfer agent and registrar for the Common Stock is Norwest Bank
Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could materially and adversely affect market prices prevailing from
time to time. Sales of substantial amounts of Common Stock of the Company in
the public market after the restrictions lapse could materially and adversely
affect the prevailing market price and the ability of the Company to raise
equity capital in the future.
   
  Upon the completion of this offering, the Company will have 7,436,064 shares
of Common Stock outstanding, assuming no exercise of options after June 30,
1996. Of these shares, the 2,300,000 shares sold in this offering will be
freely tradeable without restriction under the Securities Act, unless held by
"affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act. The remaining 5,136,064 shares of Common Stock held by
existing stockholders were issued and sold by the Company in reliance on
exemptions from the registration requirements of the Securities Act. These
shares may be sold in the public market only if registered, or pursuant to an
exemption from registration such as Rule 144, 144(k) or 701 under the
Securities Act. Such restricted shares will be available for sale in the
public market as follows: (i) approximately 271,617 shares will be eligible
for immediate sale on the date of this Prospectus, (ii) approximately
4,014,253 additional shares (including approximately 258,373 shares subject to
outstanding vested options) will be available for sale 180 days after the date
of this Prospectus upon expiration of lock-up agreements and (iii)
approximately 1,617,301 additional shares (including approximately 508,734
shares of Common Stock issuable upon exercise of certain outstanding warrants)
will be eligible for sale at various times thereafter. The Company's
directors, executive officers and certain of its stockholders, who in the
aggregate hold more than 94% of the shares of Common Stock of the Company
outstanding immediately prior to the completion of this offering, have entered
into lock-up agreements under which they have agreed not to offer, sell,
contract to sell, grant any option to purchase or otherwise dispose of, or
agree to dispose of, directly or indirectly, any shares of Common Stock or
options to acquire shares of Common Stock owned by them for a period of 180
days after the date of this Prospectus, without the prior written consent of
Montgomery Securities. Montgomery Securities may, in its sole discretion, and
at any time without notice, release all or any portion of the shares subject
to such lock-up agreements. The Company has entered into a similar agreement,
except that the Company may grant options and issue stock under its current
stock option and stock purchase plans and pursuant to other currently
outstanding options.     
   
  As of June 30, 1996, 497,250 shares were subject to outstanding options. All
of these shares are subject to the lock-up agreements described above. In
addition, 3,596,940 of the shares outstanding immediately following the
completion of this offering and up to 508,734 shares of Common Stock subject
to outstanding warrants, if exercised before the expiration of the warrants,
will be entitled to registration rights with respect to such shares upon the
release of lock-up agreements. The number of shares sold in the public market
could increase if such rights are exercised.     
   
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least
two years (including the holding period of any prior owner, except an
affiliate) is entitled to sell in "broker's transactions" or to market makers,
within any three-month period commencing 90 days after the date of this
Prospectus, a number of shares that does not exceed the greater of (i) one
percent of the number of shares of Common Stock then outstanding
(approximately 74,000 shares immediately after this offering) or (ii) the
average weekly trading volume of the Common Stock during the four calendar
weeks preceding the required filing of a Form 144 with respect to such sale.
Sales under Rule 144 are generally subject to certain manner of sale
provisions and notice requirements and to the availability of current public
information about the Company. Under Rule 144(k), a person who is not deemed
to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be
sold for at least three years (including the holding period of any prior
owner, except an affiliate), is entitled to sell such shares without having to
comply with the manner of sale, public information, volume limitation or
notice provisions of Rule 144. Under Rule 701 under the Securities Act,
persons who purchase     
 
                                      57
<PAGE>
 
shares upon exercise of options granted prior to the effective date of this
offering are entitled to sell such shares 90 days after the effective date of
this offering in reliance on Rule 144, without having to comply with the
holding period requirements of Rule 144 and, in the case of non-affiliates,
without having to comply with the public information, volume limitation or
notice provisions of Rule 144.
 
  The Securities and Exchange Commission has recently proposed reducing the
initial Rule 144 holding period to one year and the Rule 144(k) holding period
to two years. There can be no assurance as to when or whether such rule
changes will be enacted. If enacted, such modifications will have a material
effect on the times when shares of the Company's Common Stock become eligible
for resale.

</TABLE>
 
  The Representatives have advised the Company that the Underwriters propose
initially to offer the shares of Common Stock to the public on the terms set
forth on the cover page of this Prospectus. The Underwriters may allow to
selected dealers a concession of not more than $    per share, and the
Underwriters may allow, and such dealers may reallow, a concession of not more
than $    per share to certain other dealers. After the initial public
offering, the price and concessions and reallowances to dealers may be changed
by the Representatives. The Common Stock is offered subject to receipt and
acceptance by the Underwriters, and to certain other conditions, including the
right to reject orders in whole or in part.
 
  The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to a
maximum of 345,000 additional shares of Common Stock to cover over-allotments,
if any, at the same price per share as the initial 2,300,000 shares to be
purchased by the Underwriters. To the extent the Underwriters exercise this
option, each of the Underwriters will be committed, subject to certain
conditions, to purchase such additional shares in approximately the same
proportion as set forth in the above table. The Underwriters may purchase such
shares only to cover over-allotments made in connection with this offering.
 
  The Representatives have informed the Company that the Underwriters do not
expect to make sales to accounts over which they exercise discretionary
authority in excess of 5% of the number of shares of Common Stock offered
hereby.
 
  The Underwriting Agreement provides that the Company will indemnify the
several Underwriters against certain liabilities, including civil liabilities
under the Securities Act, or will contribute to payments the Underwriters may
be required to make in respect thereof.
   
  The holders of more than 94% of the shares of the Company's Common Stock
outstanding immediately prior to the completion of this offering, including
all of the Company's directors and executive officers, have agreed that, for a
period of 180 days after the date of the final Prospectus relating to this
offering, they will not, without the prior written consent of Montgomery
Securities, directly or indirectly sell, offer to sell or otherwise dispose of
any such shares of Common Stock or any right to acquire such shares. The
Company has agreed that,     
 
                                      59
<PAGE>
 
for a period of 180 days after the date of the final Prospectus relating to
this offering, it will not, without the prior written consent of Montgomery
Securities or each of the Representatives, issue, offer, sell, grant options
to purchase or otherwise dispose of any of the Company's equity securities or
any other securities convertible into or exchangeable for the Common Stock or
other equity security, other than the grant of options to purchase Common
Stock or the issuance of shares of Common Stock reserved for issuance under
the Company's stock plan's and the issuance of shares of Common Stock pursuant
to the exercise of outstanding options.
 
  Prior to this offering, there has been no public market for the Common
Stock. Consequently, the initial public offering price will be determined by
negotiations between the Company and the Representatives. Among the factors to
be considered in such negotiations are the history of, and the prospects for,
the Company and the industry in which it competes, an assessment of the
Company's management, the Company's past and present operations, its past and
present financial performance, the prospects for future earnings of the
Company, the present state of the Company's development, the general condition
of the securities markets at the time of the offering and the market prices of
and demand for publicly traded common stock of comparable companies in recent
periods.

        FORM OF REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS     
   
  When the reincorporation referred to in Note 14 of Notes to Consolidated
Financial Statements has been consummated, we will be in a position to render
the following report.

The Board of Directors
Applied Imaging Corp.:
   
  We have audited the accompanying consolidated balance sheets of Applied
Imaging Corp. and subsidiaries as of December 31, 1994 and 1995, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the years in the three-year period ended December 31, 1995.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.     
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Applied
Imaging Corp. and subsidiaries as of December 31, 1994 and 1995, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
     
  (INFORMATION AS OF JUNE 30, 1996 AND FOR THE SIX MONTHS ENDED JUNE 30, 1995
                         AND 1996 IS UNAUDITED.)     
 
(1) SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
  The Company
 
  Applied Imaging Corp. (the Company) was incorporated in 1986 to develop,
manufacture, and market automated clinical analysis systems used by
cytogenetic laboratories in prenatal genetic screening. The Company sells its
products to government and private clinical cytogenetic laboratories, research
institutions, universities, and pharmaceutical companies located primarily in
the United States, Canada, Europe, and the Pacific Rim. The Company is
currently devoting significant resources to the development of a new prenatal
screening designed to enable the detection of prenatal chromosomal disorders
through the analysis of fetal blood cells drawn from maternal blood. There
have been no revenues earned in relation to this new prenatal screening
system.
 
  Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries, Applied Imaging International,
Limited (United Kingdom) and Applied Imaging, Limited (Israel). All
significant intercompany accounts and transactions have been eliminated in
consolidation.
 
  Foreign Exchange
   
  The Company accounts for its foreign operations in accordance with Statement
of Financial Accounting Standards (SFAS) No. 52, Foreign Currency Translation.
Prior to April 1994, the functional currency for Applied Imaging
International, Limited was the British pound and, accordingly, translation
adjustments resulting from the conversion of the subsidiary's financial
statements into U.S. dollars were accumulated and reported as a separate
component of stockholders' equity. Beginning in April 1994, certain
operational and organizational changes within the Company caused the
functional currency for the Company's subsidiary to become the U.S. dollar.
Therefore, monetary assets and liabilities of the subsidiary are remeasured at
year-end exchange rates while nonmonetary items are remeasured at historical
rates. Most income and expense accounts are remeasured at the average rates in
effect during the year. Translation adjustments resulting from the conversion
of the subsidiary's financial statements into U.S. dollars are currently
recognized in the consolidated statement of operations in the year of
occurrence. The functional currency of Applied Imaging, Limited is also the
U.S. dollar.     
 
  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, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Interim Financial Data
   
  The unaudited interim consolidated financial statements have been prepared
on the same basis as the audited consolidated financial statements and, in the
opinion of management, include all adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the financial information
set forth therein, in accordance with generally accepted accounting
principles. The Company's interim results may be subject to fluctuations. As a
result, the Company believes the results of operations for the interim periods
are not necessarily indicative of the results to be expected for any future
period.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
         
      (INFORMATION AS OF JUNE 30, 1996 AND FOR THE SIX MONTHS ENDED     
                     
                  JUNE 30, 1995 AND 1996 IS UNAUDITED.)     
 
  Initial Public Offering and Unaudited Pro Forma Financial Information
   
  The Board of Directors (the Board) authorized the filing of a registration
statement with the Securities and Exchange Commission (SEC) permitting the
Company to issue and sell up to 5 million shares of its common stock in
connection with a proposed initial public offering (IPO). The unaudited pro
forma amounts included in the accompanying pro forma balance sheet as of June
30, 1996, reflect the conversion of all outstanding shares of preferred stock
into 3,960,017 shares of common stock and the net exercise of the Series F
warrants into 85,387 shares of common stock.     
 
  Revenue Recognition
 
  The Company recognizes revenue on product sales upon shipment and
concurrently accrues for expected hardware warranty expenses, hardware service
costs, and product returns. Revenue on renewed maintenance contracts,
including amounts attributable to software maintenance bundled in original
product sale agreements, is deferred and recognized ratably over the period of
the contract, generally one year.
 
  Research and Development Expenditures
 
  Research and development expenditures are charged to expense as incurred
unless they are reimbursed under a specific contract.
 
  Pro Forma Net Loss Per Common Share
   
  Pro forma net loss per share data has been computed using the weighted
average number of shares of common stock, including common equivalent shares
from stock options and warrants outstanding (when dilutive using the treasury
stock method) and the shares resulting from the conversion of all outstanding
shares of preferred stock at the closing of the IPO. Pursuant to SEC Staff
Accounting Bulletins, common equivalent shares issued during the 12-month
period prior to the initial filing of the Company's proposed IPO have been
included in the calculation as if they were outstanding for all periods
presented (even if antidilutive), using the treasury stock method and the
$15.00 anticipated initial public offering price. Due to the significant
impact of the conversion of preferred shares into common shares at the closing
of the IPO, historical net loss per common share is not meaningful and is
therefore not presented.     
 
  Cash Equivalents and Investments
 
  All highly liquid investments with maturities of three months or less when
acquired are considered by the Company to be cash equivalents.
   
  The Company adopted the provisions of SFAS No. 115, Accounting for Certain
Investments in Debt and Equity Securities, effective January 1, 1994. Under
SFAS No. 115, investments in equity and debt securities are classified in
three categories and accounted for based upon the classification. The Company
has accounted for investments in debt securities, consisting of U.S. Treasury
instruments, as "available-for-sale" and has stated applicable investments at
fair value, which approximates cost. Approximately $1,030,000 and $1,061,000
of investments as of December 31, 1995 and June 30, 1996, respectively,
consisted of a U.S. Treasury Note maturing in January 1997.     
 
  Inventories
 
  Inventories are stated at the lower of cost (first in, first out) or market.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
         
      (INFORMATION AS OF JUNE 30, 1996 AND FOR THE SIX MONTHS ENDED     
                     
                  JUNE 30, 1995 AND 1996 IS UNAUDITED.)     
 
  Property and Equipment
 
  Property and equipment are stated at cost less accumulated depreciation.
Depreciation is provided using the straight-line method over the estimated
useful lives of the respective assets, generally three to five years.
 
  Capitalized Software Costs
   
  Computer software development costs incurred subsequent to the determination
of product technological feasibility are capitalized in accordance with the
provisions of SFAS No. 86, Accounting for the Cost of Computer Software to be
Sold, Leased or Otherwise Marketed. Amortization of these capitalized costs is
provided using the greater of the ratio of revenues generated in the period
over total future revenues of the product, or the straight-line method over
the estimated market life of the related products, generally three years,
commencing when the product becomes generally available to customers. For the
years ended December 31, 1993, 1994, and 1995 and the six months ended June
30, 1995 and 1996, software development costs incurred subsequent to the
establishment of technological feasibility have not been material. The net
book value of capitalized costs is not significant and is included in other
assets on the consolidated balance sheets.     
 
  Income Taxes
 
  The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes, which prescribes an asset and liability approach
that results in the recognition of deferred tax assets and liabilities for the
expected future tax consequences of events that have been recognized in the
Company's consolidated financial statements or tax returns. In estimating
future tax consequences, SFAS No. 109 generally considers all expected future
events other than enactment of changes in tax laws or rates.
 
  Fair Value of Financial Instruments
 
  Financial instruments consist principally of cash equivalents, short-term
investments, trade receivables, notes receivable, accounts payable, and bank
debt. The carrying amounts of cash and cash equivalents, notes receivable,
trade receivables, accounts payable and bank debt approximate fair value.
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk are cash equivalents and short-term investments which the
Company places with high-credit qualified financial institutions and, by
policy, limits the amount of credit exposure to any one financial institution.
The Company sells its products to government and private clinical cytogenetic
laboratories, research institutions, universities, and pharmaceutical
companies located primarily in the United States, Canada, Europe, and the
Pacific Rim. The Company's credit risk is concentrated primarily in the United
States and Europe. The Company does not have a significant concentration of
credit risk with any single customer.
 
  Future Adoption of New Accounting Standard
 
  The Financial Accounting Standards Board recently issued SFAS No. 123,
Accounting for Stock-Based Compensation. This statement requires that the
Company either recognize in its consolidated financial statements costs
related to its stock-based employee compensation plans, including employee
stock purchase plans and stock option plans, or make pro forma disclosures of
such costs in a footnote to the consolidated financial statements. The Company
will adopt SFAS No. 123 effective January 1, 1996. Management plans to remain
on APB No. 25, Accounting for Stock Issued to Employees, as allowed under SFAS
No. 123, for purposes of measurement of compensation expense. SFAS No. 123 is
not expected to have a material effect on the Company's consolidated results
of operations.

  The line of credit and bank note payable relating to the U.S. Company cannot
exceed $1,000,000 in the aggregate and is subject to a maximum borrowing base
formula based on certain accounts receivable. This bank debt is secured by all
of the Company's domestic assets and the pledge of 660,000 shares of Applied
Imaging International, Limited representing approximately 66% of such
outstanding shares. Under the line of credit agreement, the Company cannot pay
cash dividends without the bank's prior approval. The maximum balance
outstanding during 1995 was $773,000, and the average balance during that year
was $608,000.     
   
  The bank note relating to Applied Imaging International, Limited is
denominated in British pounds and relates to the purchase of real property
from a related party in March 1994. The real property is recorded at cost,
which approximates market value, and is included in other assets in the
accompanying consolidated balance sheet. This note is secured by such real
property.

  The rights, preferences, privileges, and restrictions of the preferred stock
are as follows:
     
  .  The holders of preferred stock are entitled to preferential
     noncumulative dividends, when, as and if declared by the Board at a rate
     of $0.05 per share (in the case of Series A) and at the rate of $0.08
     per share (in the case of all other series).     
     
  .  The holders of Series A, B, C, D, F, G, H, I, and J preferred stock have
     liquidation preferences of $0.80, $1.30, $1.59, $1.80, $4.00, $4.00,
     $6.50, $5.25, and $4.25 per share, respectively, plus all declared but
     unpaid dividends.     
     
  .  Each share of preferred stock is convertible at any time at the option
     of the holder into one share of common stock (or approximately 1.04
     shares of common stock in the case of Series I). Conversion is automatic
     in the event of certain defined public offerings of common stock, the
     achievement by the Company of certain revenue and income goals, or a
     majority vote of the holders of outstanding preferred stock.     
 
  .  The preferred stock is subject to certain antidilutive provisions
     relating to stock splits and stock dividends.
 
  .  Each share of preferred stock has voting rights on an "as if converted"
     basis.
   
  As of December 31, 1995 and June 30, 1996, there were warrants outstanding
and exercisable for 110,416 shares of Series F preferred stock at $3.40 per
share which expire in 1997. However, such warrants will terminate if not
exercised or converted prior to the effective date of the Company's
contemplated IPO (Note 13).     
 
(7) COMMON STOCK
   
  The Company is authorized to issue 20,000,000 shares of common stock. As of
December 31, 1995 and June 30, 1996, there were warrants outstanding to
purchase 368,734 shares of common stock at $5.25 per share and 140,000 shares
at $4.25 per share. These warrants expire in 1998 and 2000, respectively.     
   
  As of December 31, 1995, 950,000 shares of common stock were reserved for
issuance under the Company's 1988 Amended and Restated Incentive Stock Option
Plan (the 1988 Option Plan). On June 19, 1996, the Board

authorized, effective upon the closing of the proposed IPO, reserving an
additional 450,000 shares of common stock for issuance under the 1988 Option
Plan. Under the 1988 Option Plan, stock options may be granted to Board
members, officers, key employees, and consultants at the fair market value of
the common stock at the date of the grant, as determined by the Board. Options
are exercisable over 5 to 10 years from the date of grant, and typically vest
ratably over 4 years. In 1994, the Company enacted a Directors Option Plan
designed to encourage participation on the Company's Board. Under this plan,
3,000 shares per year are automatically granted to non-employee directors. The
terms of the plan allow the granting of stock options upon initial election to
the Board and for each subsequent term on the Board. As of June 30, 1996 there
were 50,000 shares reserved for issuance under this plan and no options have
been granted. As of December 31, 1995 and June 30, 1996, 5,000 and 75,000
options were granted to Board members out of the shares reserved under the
1988 Option Plan. On June 19, 1996, the Board amended the Director Option
Plan, effective upon the closing of the proposed IPO, to increase the number
of shares subject to be automatically granted to non-employee directors for
subsequent grants from 3,000 to 5,000 shares per year and to increase the
number of shares reserved for issuance to 120,000 shares.     
   
  The Company has recorded for financial statement purposes, a deferred charge
of $1,473,000, representing the difference between the exercise price and the
deemed fair value of the Company's common stock for 246,750 shares subject to
common stock options granted in the 12-month period preceding the IPO, mainly
in the first quarter of 1996. The deferred stock compensation is being
amortized to compensation expense over the period during which the options
become exercisable, generally four years.

  On June 19, 1996, the Board adopted, effective upon the closing of the
proposed IPO, the Company's Employee Stock Purchase Plan (the Plan) whereby
eligible employees may purchase common stock through payroll deductions of up
to 10% of compensation, at a per share price of 85% of the fair market value
of the Company's common stock on the enrollment date or the exercise date,
whichever is lower. Upon the closing of the IPO there will be 200,000 shares
reserved for issuance under the Plan.     
 
(8) INCOME TAXES
 
  The Company has not recorded an income tax benefit in 1993, 1994, and 1995
due to the recording of a valuation allowance as an offset to net deferred tax
assets. A valuation allowance is provided due to uncertainties relating to the
realization of deferred tax assets.
 
  The tax effects of temporary differences that give rise to significant
portions of deferred tax assets are presented below:

</TABLE>    
 
  As of December 31, 1995, the Company had net operating loss carryforwards
for U.S. federal, U.K., and California state tax return purposes of
approximately $7,700,000, $945,000, and $1,450,000, respectively. The federal
and California net operating loss carryforwards expire in the years 2011 and
1999, respectively. The Company's U.K. net operating loss carryforward is
available indefinitely to offset its U.K. trading profits arising from
distribution operations. The difference between the tax loss carryforwards and
the accumulated deficit primarily relates to timing differences in the
recognition of deferred revenue, accrued compensation, and certain reserves.
 
  The Internal Revenue Code of 1986 and the California Conformity Act of 1987
substantially restrict the ability of a corporation to utilize existing net
operating losses and credits in the event of an "ownership change". The
several issuances of preferred stock have resulted in multiple ownership
changes since inception of the Company. The majority of the federal net
operating loss carryforwards are limited by an ownership change

occurring in July 1995. Approximately $6,700,000 of the federal net operating
loss carryforward will be subject to an annual limitation in the aggregate of
$850,000. Any unused annual limitation can be carried over and added to the
succeeding year's annual limitation within the allowable carryforward period.
Management believes that the IPO of the Company's stock will most likely
result in an ownership change, however, the July 1995 change will continue to
be the most restrictive limitation because the majority of the Company's net
operating losses were incurred prior to July 1995.
 
(9) COMMITMENTS
   
  The Company has several noncancelable operating leases for equipment,
vehicles, and facilities expiring through 2005. The facilities' leases
generally contain renewal options for periods ranging from two to three years
and require the Company to pay all executory costs such as maintenance,
property taxes, and insurance. Rent expense under operating leases aggregated
$267,000, $287,000, and $326,000 during 1993, 1994, and 1995, respectively,
and $151,000 and $165,000 during the six months ended June 30, 1995 and 1996,
respectively. The Company's primary lease commitments are for its facilities
in the United Kingdom, which aggregate approximately (Pounds)100,000 per year
through 1998, with a six-year renewal option held by the Company, and for its
facilities in the United States, which aggregate approximately $143,000 and
$42,000 for 1996 and 1997, respectively.     
 
(10) EMPLOYEE BENEFIT PLANS
   
  In January 1994, the Company implemented a retirement savings and investment
plan that is intended to qualify under Section 401(k) of the Internal Revenue
Code (the 401(k) Plan) covering all of the Company's United States-based
employees. An employee may elect to defer, in the form of contributions to the
401(k) Plan on his or her behalf, up to 15% of the total compensation that
would otherwise be paid to the employee, not to exceed the amount allowed by
applicable Internal Revenue Service guidelines. The Company matches 100% of
amounts deferred by the employee participants up to 3% of such employee's
total compensation and such matching amounts vest over a three-year period
from the initial participation date. Contributions by employees or by the
Company to the 401(k) Plan, and income earned on plan contributions, are not
taxable to employees until withdrawn from the 401(k) Plan. Contributions by
the Company are deductible by the Company when made. The Company contributed
$38,000, and $51,000 in 1994 and 1995, respectively, and $25,000 and $34,000
in the six months ended June 30, 1995 and 1996, respectively.     
   
  The Company's United Kingdom-based employees are covered by retirement
savings plans (the International Retirement Plans). Under such plans, an
employee may elect to make contributions of 3.5% of such employee's earnings.
Amounts contributed by the Company range 5.5% to 10.5% of such employee's
earnings. During 1993, 1994, and 1995, and during the six months ended June
30, 1995 and 1996, respectively, the Company made contributions to the
International Retirement Plans totaling $83,000, $60,000, $43,000, $21,000,
and $22,000. Contributions by employees or by the Company to the International
Retirement Plans, and income earned on plan contributions, are not taxable to
employees until withdrawn from such plans. Contributions by the Company are
deductible by the Company when made.

(11) FOREIGN OPERATIONS
   
  The Company markets its products worldwide from its operations in the United
States and the United Kingdom and performs research and development in the
United States and Israel. Sales from the United States are primarily to
customers within the United States. Revenues in the United Kingdom resulted
from drop shipments of product from the United States directly to customers
for the years ended December 31, 1994 and 1995 and the six months ended June
30, 1995 and 1996. Selected financial data by primary geographic area for the
years ended December 31, 1993, 1994 and 1995, and the six months ended June
30, 1995 and 1996 follow. Operating losses incurred by Israel are offset by
funding received in connection with the grant discussed at Footnote 12.

Israel subsidiary relating to its fetal cell program. All funds received by
the Company in advance of performing the related research and development are
recorded as a deferred credit in the accompanying consolidated balance sheet
and, as expenses are incurred, the deferred credit is depleted. Over the life
of the grant, the Company will receive up to $543,000 in matching funds. These
funds, as well as any accrued interest, will be required to be paid back to
the BIRD Foundation if future revenues are realized from the related research
and development activities, at the rate of 2 1/2% of such future revenues
generated in the first year such revenues occur, and 5% of revenues in
succeeding years, over a six-year period, up to a maximum of 150% of the funds
received. Of the approximately $362,000 in funding received, the Company has
recognized credits to its expenses of approximately $97,000 during 1995 and
$186,000 during the six months ended June 30, 1996.     
   
(13) PROPOSED INITIAL PUBLIC OFFERING     
   
  On June 19, 1996, the Board authorized the filing of a registration
statement with the Securities and Exchange Commission permitting the Company
to issue and sell up to 5 million shares of its common stock in connection
with a proposed IPO. If the offering is consummated under terms presently
anticipated, all of the currently outstanding preferred stock will
automatically convert into 3,960,017 shares of common stock. In addition, the
net exercise of the warrants described in Note 6 into 85,387 shares of common
stock is expected prior to the effectiveness of the Company's public offering.
The effect of the preferred stock conversion and the warrant exercise has been
reflected in the accompanying pro forma consolidated balance sheet as of June
30, 1996.     
   
(14) SUBSEQUENT EVENTS     
          
  Reincorporation     
   
  On July 15, 1996, the Board approved the Company's reincorporation in the
state of Delaware prior to the IPO, providing for 20,000,000 authorized shares
of common stock with a $.001 par value per share and for 6,000,000 authorized
shares of preferred stock with a $.001 par value per share. The accompanying
consolidated financial statements have been retroactively restated to give
effect to the reincorporation.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
   
  Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors and other corporate agents in the terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1993. as amended (the "Act"). The Registrant's Restated
Certificate of Incorporation to be filed upon the closing of the offering to
which this Registration Statement relates (Exhibit 3.3 hereto) and the
Registrant's Bylaws (Exhibit 3.4 hereto) provides for indemnification of the
Registrant's directors, officers, employees and other agents to the extent and
under the circumstances permitted by the Delaware General Corporation Law. The
Registrant also intends to enter into agreements with its directors and
executive officers that will require the Registrant among other things to
indemnify them against certain liabilities that may arise by reason of their
status or service as directors to the fullest extent not prohibited by
Delaware law.     
   
  The Underwriting Agreement provides for indemnification by the Underwriters
of the Registrant, its directors and officers, and by the Registrant of the
Underwriters, for certain liabilities, including liabilities arising under the
Act, and affords certain rights of contribution with respect thereto.     
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

under the Securities Act in reliance on Section 4(2) of the Securities Act, or
Regulation D promulgated thereunder, or Rule 701 promulgated under Section
3(b) of the Securities Act as transactions by an issuer not involving a public
offering or transactions pursuant to compensatory benefit plans and contracts
relating to compensation as provided under such Rule 701. The recipients of
securities in each such transaction represented their intention to acquire the
securities for investment only and not with a view to or for sale in
connection with any distribution thereof and appropriate legends were affixed

recipients had adequate access, through their relationships with the Company,

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Securities Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer, or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered hereunder, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
   
  The undersigned Registrant hereby undertakes that:     
     
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or

  Securities Act shall be deemed to be part of this Registration Statement as
  of the time it was declared effective.     
     
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new Registration Statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.     
 
  The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement (i) to include any
  prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii)
  to reflect in the prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereto which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement; and (iii) to include any material information with
  respect to the plan of distribution not previously disclosed in the
  registration statement or any material change to such information in the
  registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

          3.1  (i) The holders of Series A, Series B, Series C, Series D, Series
E, Series F, Series G, Series H, Series I and Series J, shall be entitled to
receive, out of the assets of the Corporation, whether such assets are capital
or surplus, an amount equal to Eighty Cents ($0.80), One Dollar and Thirty Cents

more, before any payment shall be made on or any assets distributed to the
holders of Common Stock.

               (ii) If upon liquidation, dissolution, or winding up of the
Corporation the assets to be distributed among the holders of Series A, Series
B, Series C, Series D, Series E, Series F, Series G, Series H, Series I and
Series J shall be insufficient to permit the payment to such shareholders of the
full preferential amounts to which they are entitled, then the entire assets of
the Corporation available for distribution shall be distributed ratably among
the holders of Series A, Series B, Series C, Series D, Series E, Series F,
Series G, Series H, Series I and Series J, without priority or preference, in
proportion to the full preferential amount each such holder is otherwise
entitled to receive, and no distribution of the Corporation's assets shall be

a sale of all or substantially all of the assets of the Corporation in which all
of the shareholders of the Corporation immediately prior to such transaction own
less than 50% of the voting securities of the surviving or controlling entity

or winding up, within the meaning of this Section 3; provided that the holders
of Series A, Series B, Series C, Series D, Series E, Series F, Series G, Series
H, Series I, Series J and Common Stock shall be paid in cash or in securities
received from the acquiring entity or in a combination thereof (in the same
proportions as the consideration received in the transaction).  Any securities
to be delivered to the holders of the Series A, Series B, Series C, Series D,
Series E, Series F, Series G, Series H, Series I, Series J and Common Stock upon
a reorganization, consolidation or merger of the Corporation, or a sale of all
or substantially all of the assets of the Corporation, shall be valued as

               (i)   If traded on a securities exchange, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the 30-day period ending three (3) business days prior to the
closing;

               (ii)  If actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over the 30-day period ending
three (3) business days prior to the closing; and

               (iii) If there is no active public market, the value shall be the
fair market value thereof, as mutually determined by the corporation and the
holders of not less than a majority of the outstanding shares of Preferred
Stock, provided that if the corporation and the holders of a majority of the
outstanding shares of Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock.

required by law, each holder of shares of Series A, Series B, Series C, Series
D, Series E, Series F, Series G, Series H, Series I and Series J shall be
entitled to vote on all matters and shall be entitled to the number of votes
equal to the largest number of full shares of Common Stock into which such

Series H, Series I or Series J could be converted, pursuant to the provisions of
Section 5 hereof, at the record date for the determination of shareholders
entitled to vote on such matters or, if no such record date is established, at

     5.   Conversion of Preferred Stock.  The holders of Preferred Stock shall
          -----------------------------                                       
have the following conversion rights:

          5.1    Automatic Conversion.
                 -------------------- 

                 5.1.1  Each share of each series of Preferred Stock shall
automatically be converted into shares of Common Stock at the Conversion Price
(as defined below) for such series then in effect, immediately upon either (i)
the sale of Common Stock by the Corporation through an underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, at a per share public offering price (prior to
underwriting commissions and expenses) of not less than $6.00 per share and with
gross proceeds (prior to underwriting commissions and expenses) of $7,500,000,
(ii) the Corporation's reporting audited consolidated revenues of at least
$50,000,000 for a fiscal year and audited consolidated income before taxes and
extraordinary items (determined in accordance with generally accepted accounting
principles) of at least 10% of the revenues for the same period, or (iii) upon
the vote approving such conversion by holders of at least a majority of the
outstanding shares of such series; however, such conversion of each such series
shall be conditioned upon the Corporation paying all declared and unpaid
dividends

                                      -4-
<PAGE>
 
on such series, to and including the date of conversion.  The Corporation, may,
at its option, in lieu of making a cash payment of all declared dividends, make
payment thereof in whole shares of Common Stock, valued at such Conversion Price
for such series, plus cash in lieu of any fractional shares, so that such cash
plus the value of such Common Stock shall equal the amount of accrued and unpaid
dividends.

                 5.1.2 Upon the occurrence of any event specified in Section
5.1.1 above as to a series of Preferred Stock, the outstanding shares of such
series shall be converted automatically without any further action by the
holders of such shares and whether or not the certificates repre senting such
shares are surrendered to the Corporation or its transfer agent. Upon the
automatic conversion of a series of Preferred Stock, the holders of such series
shall surrender the certificates representing such shares at the office of the
Corporation or transfer agent for the Common Stock as hereinafter provided, or
shall notify the Corporation or transfer agent that such certificates have been
lost, stolen or destroyed and execute an agreement satisfactory to the
Corporation to indemnify the Corporation from any loss incurred by it in
connection therewith. The Corporation shall then cause to be issued and
delivered to such holders, promptly at such office and in their names as shown
on such surrendered certificates, certificates for the number of shares of
Common Stock into which the shares of such series of Preferred Stock, so
surrendered were convertible on the date on which automatic conversion occurred.

          5.2    Right to Convert.  Each share of each series of Preferred Stock
                 ----------------                                               
shall be convertible, at the option of the holder thereof, at any time after the
date of issuance of such share, at the office of the Corporation or any transfer
agent for such series or for Common Stock, into fully paid and nonassessable
shares of Common Stock, at the Conversion Price for such series (as defined
below) in effect at the time of the conversion determined as provided below.

          5.3    Mechanics of Voluntary Conversion.
                 --------------------------------- 

                 5.3.1  A holder of shares of a series of Preferred Stock may
only convert such shares into shares of Common Stock by: (i) surrendering the
certificate or certificates representing the shares of such series to be
converted, duly endorsed, at the office of the Corporation or any transfer agent
for such series or Common Stock, and (ii) giving written notice to the
Corporation at such office stating that such holder elects to convert all or
part of the shares of such series held by such holder. The Corporation shall
promptly issue and deliver at such office to such holder of such series a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled and a certificate or certificates for the number
of shares of such series not converted, if any.

                 5.3.2  Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of the surrender of the
shares of such series of Preferred Stock to be converted as provided in Section
5.3.1 above, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date.

unless adjusted as provided herein.

                5.4.7 Each share of Series G shall be convertible into the

          5.5  Adjustment for Stock Issuances Below Conversion Price.  If the
               -----------------------------------------------------         
Corporation shall at any time or from time to time after the issuance of any
shares of Series H, Series I or Series J issue (or, pursuant to this Section 5.5
hereof, shall be deemed to have issued) any Common Stock other than "Excluded
Stock" (as defined below) for a consideration per share less than the Conversion
Price for Series H, Series I or Series J in effect immediately prior to the
issuance of such Common Stock (excluding stock dividends, subdivisions, split-
ups, combinations, dividends or recapitalizations which are covered by Sections
5.6, 5.7, 5.8, 5.9, and 5.10), the Conversion Price for Series H, Series I or

quotient obtained by dividing:

               (i)   an amount equal to the sum of

                     (x) the total number of shares of Common Stock outstanding
(including any shares of Common Stock issuable upon conversion of such series of
Preferred Stock, or deemed to have been issued pursuant to subdivision (3) of
this clause (i) and to clause (ii) below) immediately prior to such issuance
multiplied by the Conversion Price for such series of Preferred Stock in effect
immediately prior to such issuance, plus

                     (y) the consideration received by the corporation upon such
issuance, by

               (ii) the total number of shares of Common Stock outstanding
immediately prior to such issuance of Common Stock (including any shares of
Common Stock issuable upon conversion of Series H, Series I or Series J
Preferred Stock or deemed to have been issued pursuant to subdivision (3) of
this clause (i) and to clause (ii) below) plus the number of shares of Common
Stock actually issued in the transaction which resulted in the adjustment
pursuant to this Section 5.5.

<PAGE>
 
               For the purposes of any adjustment of the Conversion Price for
Series H, Series I or Series J Preferred Stock pursuant to clauses (i) and (ii),
the following provisions shall apply:

               (1) In the case of the issuance of Common Stock for cash, the
consideration shall be deemed to be the amount of cash paid therefor after
deducting any discounts or commissions paid or incurred by the corporation in
connection with the issuance and sale thereof.

               (2) In the case of the issuance of Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as reasonably determined by
the board of directors of the corporation, in accordance with generally accepted
accounting treatment.

               (3) In the case of the issuance of (i) options to purchase or
rights to subscribe for Common Stock (other than Excluded Stock), (ii)
securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded Stock), or (iii) options to purchase or rights to subscribe
for such convertible or exchangeable securities:

                   (A) the aggregate maximum number of shares of Common Stock
deliverable upon exercise of such options to purchase or rights to subscribe for
Common Stock shall be deemed to have been issued at the time such options or
rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1) and (2) above), if any,
received by the corporation upon the issuance of such options or rights plus the
minimum purchase price provided in such options or rights for the Common Stock
covered thereby;

                   (B) the aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities, or upon the exercise of options to purchase or rights
to subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof, shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration received by the corporation for any
such securities and related options or rights (excluding any cash received on
account of accrued interest or accrued dividends), plus the additional minimum
consideration, if any, to be received by the corporation upon the conversion or
exchange of such securities or the exercise of any related options or rights
(the consideration in each case to be determined in the manner provided in
subdivisions (1) and (2) above);

                   (C) on any change in the number of shares of Common Stock
deliverable upon exercise of any such options or rights or conversion of or
exchange for such convertible or exchangeable securities, or on any change in
the minimum purchase price of such options, rights or securities, other than a
change resulting from the antidilution provisions of such options, rights or
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have obtained had the adjustment made upon (x) the
issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change or (y) the options or rights

                                      -8-
<PAGE>
 
related to such securities not converted or exchanged prior to such change, as
the case may be, been made upon the basis of such change; and

                   (D) on the expiration of any such options or rights, the
termination of any such rights to convert or exchange or the expiration of any
options or rights related to such convertible or exchangeable securities, the
Conversion Price shall forthwith be readjusted to such Conversion Price as would
have obtained had the adjustment made upon the issuance of such options, rights,
convertible or exchangeable securities or options or rights relate to such
convertible or exchangeable securities, as the case may be, been made upon the
basis of the issuance of only the number of shares of Common Stock actually
issued upon the exercise of such options or rights, upon the conversion or
exchange of such convertible or exchangeable securities or upon the exercise of
the options or rights related to such convertible or exchangeable securities, as
the case may be.

          (4) If the Corporation shall issue (or pursuant to Section 5.5 hereof,
shall be deemed to have issued) in the same transaction (or a series of related
transactions) any Common Stock other than Excluded Stock at different prices,
the shares of Common Stock issued in such transaction (or series of related
transactions) shall be deemed to have been issued simultaneously for purposes of
the computations in this Section 5.5.

          5.5.1  "Excluded Stock" shall mean:

                 (i)    all shares of Common Stock issued and outstanding on the
date this certificate is filed with the California Secretary of State and all
shares of Common Stock issuable upon exercise of options and warrants
outstanding on the date this certificate is filed with the California Secretary
of State;

                 (ii)   all shares of Preferred Stock outstanding on the date
this certificate is filed with the California Secretary of State and the Common
Stock into which such shares of Preferred Stock are convertible;

                 (iii)  all shares of Common Stock or other securities hereafter
issued to officers, directors, consultants or employees of or scientific
advisors to the corporation which issuances are approved by of the board of
directors of the corporation;

                 (iv)   all shares of Series J Preferred Stock and the Common
Stock into which such shares of Series J Preferred Stock are convertible; and

                 (v)    all shares of Common Stock issuable upon exercise or
conversion of a warrant hereafter issued to Allen & Company Incorporated.

     All outstanding shares of Excluded Stock (including shares issuable upon
conversion of the Preferred Stock) shall be deemed to be outstanding for all
purposes of the computations of Section 5.5 above.

          5.6  Adjustment for Stock Splits and Combinations.  If the Corporation
               --------------------------------------------                     
shall at any time or from time to time after the issuance of any shares of a
series of Preferred Stock effect a subdivision of any outstanding Common Stock,
the Conversion Price then in effect for such series immediately before that
subdivision shall be proportionately decreased.  Conversely, if the Corpora tion
shall at any time or from time to time after the issuance of any shares of a
series of Preferred Stock combine the outstanding shares of Common Stock, the
Conversion Price then in effect for such series immediately before the
combination shall be proportionately increased.  Any adjustment under this
Section 5.6 shall become effective at the close of business on the date the
subdivision or combination becomes effective.

          5.7  Adjustment for Certain Dividends and Distributions.  If the
               --------------------------------------------------         
Corporation at any time or from time to time shall make or issue, or fix a
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in additional shares of Common
Stock, in each such event the Conversion Prices then in effect for each series
of Preferred Stock shall be decreased as of the time of such issuance or, if
such record date shall have been fixed, as of the close of business on such
record date, by multiplying the Conversion Price of each series then in effect
by a fraction:

               5.7.1  The numerator of which shall be the total number of shares
of Common Stock issued and outstanding immediately prior to the time of such
issuance, or the close of business on such record date, and

               5.7.2  The denominator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance, or the close of business on such record date, plus the number of
shares of Common Stock issuable in payment of such dividend or distribution;
provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Prices of each series shall be recomputed accordingly
as of the close of business on such record date, and thereafter the Conversion
Price of each series shall be adjusted pursuant to this Section 5.7 as of the
time of actual payment of such dividend or distribution.

          5.8  Adjustment for Other Dividends and Distributions.  If the
               ------------------------------------------------         
Corporation at any time or from time to time shall make or issue, or fix a
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the
Corporation, other than shares of Common Stock, then and in each such event
provisions shall be made so that the holders of each series of Preferred Stock
shall receive upon conversion of their shares, in addition to the number of
shares of Common Stock receivable upon such conversion, the amount of securities
of the Corporation which they would have received had their shares of such
series been converted into Common Stock on the date of such dividend or
distribution and had they thereafter, during the period from the date of such
event to and including the conversion date, retained such securities receivable
by them as provided above during such period, giving application to all
applicable adjustments called for during such periods under this Section 5 with
respect to the rights of the holders of each series of Preferred Stock.

          5.9  Adjustment for Recapitalizations, Reclassifications, or Other
               -------------------------------------------------------------
Changes to Common Stock.  If the Common Stock shall be changed into the same or
- -----------------------                                                        
a different number of shares of any class or classes of stock, whether by a
recapitalization, reclassification or otherwise (other than a subdivision or
combination of shares or stock dividend provided for above, or a capital
reorganization, merger, consolidation or sale of assets provided for below),
then and in each such event the holders of shares of each series of Preferred
Stock shall have the right thereafter to convert such shares into the kind and
amount of shares of stock and other securities and property receivable upon such
reorganization, reclassification or other change, by holders of the number of
shares of Common Stock into which such shares of such series might have been
converted immediately prior to such reorganization, reclassification or change,
all subject to further adjustment as provided in this Certificate.

          5.10  Adjustment for Capital Reorganizations, Mergers, Consolidations,
                ----------------------------------------------------------------
or Sales of Assets.  If at any time or from time to time there shall be a
- ------------------                                                       
capital reorganization of the capital stock of the Corporation (other than a
subdivision, combination, stock dividend, recapitalization, reclassification or
other change to Common Stock provided for above in this Section 5), or a merger
or consolidation of the Corporation with or into another corporation, or the
sale of all or substantially all of the Corporation's properties and assets to
any other person, then, as a part of such capital reorganization, merger,
consolidation or sale, provision shall be made so that the holders of each
series of Preferred Stock shall thereafter be entitled to receive upon
conversion of the shares of such series the number of shares of stock or other
securities or property of the Corporation, or of the successor corporation
resulting from such merger, consolidation or sale, to which a holder of Common
Stock deliverable upon conversion would have been entitled on such capital
reorganization, merger, consolidation or sale.  In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the holders of each series of Preferred Stock
after such capital reorganization, merger, consolidation or sale so that the
provisions of this Section 5 (including adjustment of the Conversion Prices then
in effect for each series of Preferred Stock and the number of shares issuable
upon conversion of each series of Preferred Stock) shall be applicable after

          5.12  Notice of Record Date.  In the event of any recapitalization,
                ---------------------                                        
reclassification or other change to the Common Stock, any capital
reorganization, any merger or consolidation of the Corporation, any sale of all
or substantially all of the Corporation's properties and assets to another
person, or any voluntary or involuntary liquidation of the Corporation, the
Corporation shall mail to each holder of shares of Preferred Stock at least
thirty (30) days prior to any record date with respect thereto, a notice
specifying the date on which such recapitalization, reclassification or other
change, capital reorganization, merger, consolidation, or liquidation is
expected to be effective, and the time, if any, that is to be fixed, as to when
the holders of record of Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such recapitalization, reclassification or other
change, capital reorganization, merger, consolidation, or liquidation.

          5.13  Fractional Shares.  No fractional shares of Common Stock shall

be issued upon conversion of shares of Preferred Stock.  The number of shares of
Common Stock to which a holder of shares of a series of Preferred Stock is
entitled shall be based on the aggregate number of shares of such series being
converted at any one time.  In lieu of any fractional share to which such holder
would otherwise be entitled, the Corporation shall pay cash equal to the product
of such fraction multiplied by the fair market value of one share of the
Corporation's Common Stock on the date of conversion, as determined in good
faith by the Board of Directors and calculated to the nearest whole cent.

          5.14  Reservation of Stock Issuable Upon Conversion.  The Corporation
                ---------------------------------------------                  
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of Preferred Stock, and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such a number of shares as shall be sufficient for such purpose.

          5.15  Notices.  Any notice required by the provisions of this Section

and addressed to such holder at his address appearing on the books of the
Corporation, or upon delivery if personally delivered, sent by messenger or

or amounts per share, which the shares of such class or series of Preferred
Stock shall be entitled to receive upon any voluntary or involuntary

      The registered office of the corporation shall be fixed in the certificate
of incorporation of the corporation.

      1.2  OTHER OFFICES
           -------------

      The board of directors may at any time establish branch or subordinate

                            MEETINGS OF STOCKHOLDERS
                            ------------------------

      2.1  PLACE OF MEETINGS
           -----------------

      Meetings of stockholders shall be held at any place within or outside the
State of Delaware designated by the board of directors.  In the absence of any
such designation, stockholders' meetings shall be held at the principal
executive office of the corporation.

      2.2  ANNUAL MEETING
           --------------

      The annual meeting of stockholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation, the annual meeting of stockholders shall be held on the second
Tuesday of May in each year at 10:00 a.m. However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding full business day. At the meeting, directors shall be elected, and
any other proper business may be transacted.

      2.3  SPECIAL MEETING
           ---------------

      A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president, or by
one or more stockholders holding shares in the
<PAGE>
 
aggregate entitled to cast not less than ten percent (10%) of the votes at that
meeting.  No other person or persons are permitted to call a special meeting.

      If a special meeting is called by any person or persons other than the
board of directors, then the request shall be in writing, specifying the time of
such meeting and the general nature of the business proposed to be transacted,
and shall be delivered personally or sent by registered mail or by telegraphic
or other facsimile transmission to the chairman of the board, the president, or
the secretary of the corporation.  The officer receiving the request shall cause
notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.6 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request.  If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice.  Nothing contained in this paragraph of this
Section 2.3 shall be construed as limiting, fixing or affecting the time when a
meeting of stockholders called by action of the board of directors may be held.

      2.4  NOTICE OF STOCKHOLDERS' MEETINGS
           --------------------------------

      All notices of meetings of stockholders shall be sent or otherwise given
in accordance with Section 2.6 of these bylaws not less than ten (10) nor more
than sixty (60) days before the date of the meeting. The notice shall specify
the place, date and hour of the meeting and (i) in the case of a special
meeting, the purpose or purposes for which the meeting is called (no business
other than that specified in the notice may be transacted) or (ii) in the case
of the annual meeting, those matters which the board of directors, at the time
of giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

      2.5  ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS
           ---------------------------------------------------------------

      Subject to the rights of holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation,

      (a)  nominations for the election of directors, and

      (b)  business proposed to be brought before any stockholder meeting

may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business proposed is otherwise proper business
before such meeting.  However, any such stockholder may nominate one or more
persons for election as directors at a meeting or propose business to be brought
before a meeting, or both, only if such stockholder has given timely notice in
proper written form of their intent to make such nomination or nominations or to
propose such business.  To be timely, such stockholder's notice

                                      -2-
<PAGE>
 
must be delivered to or mailed and received at the principal executive offices
of the corporation not less than one hundred twenty (120) calendar days in
advance of the date specified in the corporation's proxy statement released to
stockholders in connection with the previous year's annual meeting of
stockholders; provided, however, that in the event that no annual meeting was
held in the previous year or the date of the annual meeting has been changed by
more than thirty (30) days from the date contemplated at the time of the
previous year's proxy statement, notice by the stockholder to be timely must be
so received a reasonable time before the solicitation is made.  To be in proper
form, a stockholder's notice to the secretary shall set forth:

      (i)   the name and address of the stockholder who intends to make the
      nominations or propose the business and, as the case may be, of the person
      or persons to be nominated or of the business to be proposed;

      (ii)  a representation that the stockholder is a holder of record of
      stock of the corporation entitled to vote at such meeting and, if
      applicable, intends to appear in person or by proxy at the meeting to
      nominate the person or persons specified in the notice;

      (iii) if applicable, a description of all arrangements or understandings
      between the stockholder and each nominee and any other person or persons
      (naming such person or persons) pursuant to which the nomination or
      nominations are to be made by the stockholder;

      (iv)  such other information regarding each nominee or each matter of
      business to be proposed by such stockholder as would be required to be
      included in a proxy statement filed pursuant to the proxy rules of the
      Securities and Exchange Commission had the nominee been nominated, or
      intended to be nominated, or the matter been proposed, or intended to be
      proposed by the board of directors; and

      (v)   if applicable, the consent of each nominee to serve as director of
      the corporation if so elected.

      The chairman of the meeting shall refuse to acknowledge the nomination of
any person or the proposal of any business not made in compliance with the
foregoing procedure.

      2.6   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
            --------------------------------------------

      Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication.  Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice.  Notice shall be deemed to have been
given at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.

                                      -3-
<PAGE>
 
      An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

      2.7  QUORUM
           ------

      The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation.  If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.7 of these bylaws.

      When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

      If a quorum be initially present, the stockholders may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

      2.8  ADJOURNED MEETING; NOTICE
           -------------------------

      When a meeting is adjourned to another time and place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting.  If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

      2.9  VOTING
           ------

      The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

      Except as may be otherwise provided in the certificate of incorporation or
these bylaws, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder and stockholders shall not be entitled to
cumulate their votes in the election of directors or with respect to any matter
submitted to a vote of the stockholders.

                                      -4-
<PAGE>
 
      Notwithstanding the foregoing, if the stockholders of the corporation are
entitled, pursuant to Sections 2115 and 301.5 of the California Corporations
Code, to cumulate their votes in the election of directors, each such
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes that such stockholder normally
is entitled to cast) only if the candidates' names have been properly placed in
nomination (in accordance with these bylaws) prior to commencement of the
voting, and the stockholder requesting cumulative voting has given notice prior
to commencement of the voting of the stockholder's intention to cumulate votes.
If cumulative voting is properly requested, each holder of stock, or of any
class or classes or of a series or series thereof, who elects to cumulate votes
shall be entitled to as many votes as equals the number of votes that (absent
this provision as to cumulative voting) he or she would be entitled to cast for
the election of directors with respect to his or her shares of stock multiplied
by the number of directors to be elected by him, and he or she may cast all of
such votes for a single director or may distribute them among the number to be
voted for, or for any two or more of them, as he or she may see fit.

      2.10  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING
            ------------------------------------------

      For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

      If the board of directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the business day next

      Every person entitled to vote for directors, or on any other matter, shall
have the right to do so either in person or by one or more agents authorized by
a written proxy signed by the person and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy

Delaware.

the corporation's vice presidents, shall call the meeting of the stockholders to
order, and shall act as chairman of the meeting.  In the absence of the
president, the chairman of the board, and all of the vice presidents, the
stockholders shall appoint a chairman for such meeting.  The chairman of any
meeting of stockholders shall determine the order of business and the procedures
at the meeting, including such matters as the regulation of the manner of voting
and the conduct of business.  The secretary of the corporation shall act as
secretary of all meetings of the stockholders, but in the absence of the
secretary at any meeting of the stockholders, the chairman of the meeting may
appoint any person to act as secretary of the meeting.

      2.13  LIST OF STOCKHOLDERS ENTITLED TO VOTE
            -------------------------------------

      The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so

      Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

                                   DIRECTORS
                                   ---------

      3.1  POWERS
           ------

      Subject to the provisions of the General Corporation Law of Delaware and
to any limitations in the certificate of incorporation or these bylaws relating
to action required to be approved by the stockholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the board of
directors.


      3.2  NUMBER OF DIRECTORS
           -------------------

      The board of directors shall not be less than five (5) nor more than
nine(9) members.  The exact number of directors shall be eight (8) until
changed, within the limits specified above by a bylaw amending this Section 3.2
duly adopted by the board of directors or the stockholders.  The indefinite
number of directors may be changed, or a definite number may be fixed without
provision for an indefinite number, by an amendment to this bylaw, duly adopted
by the board of directors or by the stockholders, or by a duly adopted amendment
to the certificate of incorporation.  No reduction of the authorized number of
directors shall have the effect of removing any director before that director's
term of office expires.

      Upon the closing of the first sale of the corporation's common stock
pursuant to a firmly underwritten registered public offering (the "IPO"), the
directors shall be divided into three classes, with the term of office of the
first class, which class shall initially consist of three directors, to expire
at the first annual meeting of stockholders held after the IPO; the term of
office of the second class, which class shall initially consist of three
directors, to expire at the second annual meeting of stockholders held after the
IPO; the term of office of the third class, which class shall initially consist
of two directors, to expire at the third annual meeting of stockholders held
after the IPO; and thereafter for each such term to expire at each third
succeeding annual meeting of stockholders held after such election.

      3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS
           ----------------------------------------

      Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Each director, including a director elected or appointed to fill
a vacancy, shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.

      3.4  RESIGNATION AND VACANCIES
           -------------------------

      Any director may resign effective on giving written notice to the chairman
of the board, the president, the secretary or the board of directors, unless the
notice specifies a later time for that resignation to become effective. If the
resignation of a director is effective at a future time, the board of directors
may elect a successor to take office when the resignation becomes effective.

                                      -7-
<PAGE>
 
      Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum). Each director so elected shall hold office
until the next annual meeting of the stockholders and until a successor has been
elected and qualified.

      Unless otherwise provided in the certificate of incorporation or these
bylaws:

               (i)   Vacancies and newly created directorships resulting from
any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

               (ii)  Whenever the holders of any class or classes of stock or
series thereof are entitled to elect one or more directors by the provisions of
the certificate of incorporation, vacancies and newly created directorships of
such class or classes or series may be filled by a majority of the directors
elected by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

      If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

      If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent of the total number of the shares at the time outstanding
having the right to vote for such directors, summarily order an election to be
held to fill any such vacancies or newly created directorships, or to replace
the directors chosen by the directors then in office as aforesaid, which
election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

      3.5  REMOVAL OF DIRECTORS
           --------------------

      Unless otherwise restricted by statute, by the certificate of
incorporation or by these bylaws, any director or the entire board of directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that, if and so long as stockholders of the corporation are entitled to
cumulative voting, if less than the entire board is to be removed, no director
may be removed without cause if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the entire
board of directors.

waiver of notice, whether before or after the meeting, or (ii) who attends the
meeting other than for the express purposed of objecting at the beginning of the
meeting to the transaction of any business because the meeting is not lawfully
called or convened. All such waivers shall be filed with the corporate records
or made part of the minutes of the meeting. A waiver of notice need not specify
the purpose of any regular or special meeting of the board of directors.

assistant secretaries in the order determined by the board of directors (or if
there be no such determination, then in the order of their election) shall, in
the absence of the secretary or in the event of his or her inability or refusal
to act, perform the duties and exercise the powers of the secretary and shall
perform such other duties and have such other powers as the board of directors
may from time to time prescribe.

      5.12  ADMINISTRATIVE OFFICERS
            -----------------------

      In addition to the Corporate Officers of the corporation as provided in
Section 5.1 of these bylaws and such subordinate Corporate Officers as may be
appointed in accordance with Section 5.3 of these bylaws, there may also be such
Administrative Officers of the corporation as may be designated and appointed
from time to time by the president of the corporation.  Administrative Officers
shall perform such duties and have such powers as from time to time may be
determined by the president or the board of directors in order to assist the
Corporate Officers in the furtherance of their duties.  In the performance of
such duties and the exercise of such powers, however, such Administrative
Officers shall have limited authority to act on behalf of the corporation as the
board of directors shall establish, including but not limited to limitations on
the dollar amount and on the scope of agreements or commitments that may be made
by such Administrative Officers on behalf of the corporation, which limitations
may not be exceeded by such individuals or altered by the president without
further approval by the board of directors.

      5.13  AUTHORITY AND DUTIES OF OFFICERS
            --------------------------------

      In addition to the foregoing powers, authority and duties, all officers of

such duties in the management of the business of the corporation as may be
designated from time to time by the board of directors.

               -------------------------------------------------
                                AND OTHER AGENTS
                                ----------------

      6.1  INDEMNIFICATION OF DIRECTORS AND OFFICERS
           -----------------------------------------

      The corporation shall, to the maximum extent and in the manner permitted
by the General Corporation Law of Delaware as the same now exists or may
hereafter be amended, indemnify any person against expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement actually and
reasonably incurred in connection with any threatened, pending or completed
action, suit, or proceeding in which such person was or is a party or is
threatened to be made a party by reason of the fact that such person is or was a
director or officer of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation shall mean any person (i) who is or
was a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

      The corporation shall be required to indemnify a director or officer in
connection with an action, suit, or proceeding (or part thereof) initiated by
such director or officer only if the initiation of such action, suit, or
proceeding (or part thereof) by the director or officer was authorized by the
Board of Directors of the corporation.

      The corporation shall pay the expenses (including attorney's fees)
incurred by a director or officer of the corporation entitled to indemnification
hereunder in defending any action, suit or proceeding referred to in this
Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer to repay all amounts
advanced if it should ultimately be determined that the director of officer is
not entitled to be indemnified under this Section 6.1 or otherwise.

      The rights conferred on any person by this Article shall not be exclusive
of any other rights which such person may have or hereafter acquire under any
statute, provision of the corporation's Certificate of Incorporation, these
bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

      Any repeal or modification of the foregoing provisions of this Article
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

                                     -16-

      6.2  INDEMNIFICATION OF OTHERS
           -------------------------

      The corporation shall have the power, to the maximum extent and in the
manner permitted by the General Corporation Law of Delaware as the same now
exists or may hereafter be amended, to indemnify any person (other than
directors and officers) against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred in
connection with any threatened, pending or completed action, suit, or
proceeding, in which such person was or is a party or is threatened to be made a
party by reason of the fact that such person is or was an employee or agent of
the corporation. For purposes of this Section 6.2, an "employee" or "agent" of
the corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

      6.3  INSURANCE
           ---------

      The corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

      7.1  MAINTENANCE AND INSPECTION OF RECORDS
           -------------------------------------

      The corporation shall, either at its principal executive office or at such
place or places as designated by the board of directors, keep a record of its
stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these bylaws as amended to date,
accounting books and other records of its business and properties.

      Any stockholder of record, in person or by attorney or other agent, shall,
upon written demand under oath stating the purpose thereof, have the right
during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the

                                     -17-
<PAGE>
 
stockholder. The demand under oath shall be directed to the corporation at its
registered office in Delaware or at its principal place of business.

      7.2  INSPECTION BY DIRECTORS
           -----------------------

      Any director shall have the right to examine (and to make copies of) the
corporation's stock ledger, a list of its stockholders and its other books and
records for a purpose reasonably related to his or her position as a director.

      7.3  ANNUAL STATEMENT TO STOCKHOLDERS
           --------------------------------

      The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.

      7.4  REPRESENTATION OF SHARES OF OTHER CORPORATIONS
           ----------------------------------------------

      The chairman of the board, if any, the president, any vice president, the
chief financial officer, the secretary or any assistant secretary of this
corporation, or any other person authorized by the board of directors or the
president or a vice president, is authorized to vote, represent and exercise on
behalf of this corporation all rights incident to any and all shares of the
stock of any other corporation or corporations standing in the name of this
corporation.  The authority herein granted may be exercised either by such
person directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.

      7.5  CERTIFICATION AND INSPECTION OF BYLAWS
           --------------------------------------

      The original or a copy of these bylaws, as amended or otherwise altered to
date, certified by the secretary, shall be kept at the corporation's principal
executive office and shall be open to inspection by the stockholders of the
corporation, at all reasonable times during office hours.


                                  ARTICLE VIII

                                GENERAL MATTERS
                                ---------------

      8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
           -----------------------------------------------------

      For purposes of determining the stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the board of directors may fix, in advance, a record date, which shall not
precede the date upon which the resolution fixing the record date is adopted and
which shall not be more than sixty (60) days before any such action. In that
case, only stockholders of record at the close of business on the date so fixed
are entitled to

                                     -18-
<PAGE>
 
receive the dividend, distribution or allotment of rights, or to exercise such
rights, as the case may be, notwithstanding any transfer of any shares on the
books of the corporation after the record date so fixed, except as otherwise
provided by law.

      If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board of directors adopts the applicable
resolution.

      8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS
           -----------------------------------------

      From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

      8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED
           --------------------------------------------------

      The board of directors, except as otherwise provided in these bylaws, may
authorize and empower any officer or officers, or agent or agents, to enter into
any contract or execute any instrument in the name of and on behalf of the
corporation; such power and authority may be general or confined to specific
instances.  Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by any contract or engagement or to
pledge its credit or to render it liable for any purpose or for any amount.

      8.4  STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES
           ------------------------------------------------

      The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and, upon request,
every holder of uncertificated shares, shall be entitled to have a certificate
signed by, or in the name of the corporation by, the chairman or vice-chairman
of the board of directors, or the president or vice-president, and by the
treasurer or an assistant treasurer, or the secretary or an assistant secretary
of such corporation representing the number of shares registered in certificate
form. Any or all of the signatures on the certificate may be a facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he or she were such officer,
transfer agent or registrar at the date of issue.

      Certificates for shares shall be of such form and device as the board of
directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,

                                     -19-
<PAGE>
 
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

      Upon surrender to the secretary or transfer agent of the corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

      The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, or upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

      8.5  SPECIAL DESIGNATION ON CERTIFICATES
           -----------------------------------

      If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

      8.6  LOST CERTIFICATES
           -----------------

      Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

<PAGE>
 
      8.7  TRANSFER AGENTS AND REGISTRARS
           ------------------------------

      The board of directors may appoint one or more transfer agents or transfer
clerks, and one or more registrars, each of which shall be an incorporated bank
or trust company -- either domestic or foreign, who shall be appointed at such
times and places as the requirements of the corporation may necessitate and the
board of directors may designate.

      8.8  CONSTRUCTION; DEFINITIONS
           -------------------------

      Unless the context requires otherwise, the general provisions, rules of
construction and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws.  Without limiting the generality of
this provision, as used in these bylaws, the singular number includes the
plural, the plural number includes the singular, and the term "person" includes
both an entity and a natural person.


                                   ARTICLE IX

                                   AMENDMENTS
                                   ----------

      The original or other bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote or by the board of directors of
the corporation.  The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their power
to adopt, amend or repeal bylaws.

      Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

                             APPLIED IMAGING CORP.

                           INDEMNIFICATION AGREEMENT


     This Indemnification Agreement ("Agreement") is effective as of
_______________, 1996 by and between Applied Imaging Corp., a Delaware
corporation (the "Company"), and ___________________________________,
("Indemnitee").

     WHEREAS, effective as of the date hereof, Applied Imaging Corp., a
California corporation, is reincorporating into Delaware;

     WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and its related
entities;

     WHEREAS, in order to induce Indemnitee to continue to provide services to
the Company, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

     WHEREAS, the Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for the Company's directors, officers, employees,
agents and fiduciaries, the significant increases in the cost of such insurance
and the general reductions in the coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited; and

     WHEREAS, in connection with the Company's reincorporation, the Company and
Indemnitee desire to continue to have in place the additional protection
provided by an indemnification agreement to provide indemnification and
advancement of expenses to the Indemnitee to the maximum extent permitted by
Delaware law;

     WHEREAS, in view of the considerations set forth above, the Company desires
that Indemnitee shall be indemnified and advanced expenses by the Company as set
forth herein;

     NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth below.

     1.  Certain Definitions.
         ------------------- 

         (a) "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended) or group acting in concert, other than a trustee
<PAGE>
 
or other fiduciary holding securities under an employee benefit plan of the
Company acting in such capacity or a corporation owned directly or indirectly by
the stockholders of the Company in substantially the same proportions as their
ownership of stock of the Company, becomes the "beneficial owner" (as defined in
Rule 13d-3 under said Act), directly or indirectly, of securities of the Company
representing more than 50% of the total voting power represented by the
Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two thirds (2/3) of the directors then still in
office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason to constitute a majority thereof, (iii) the stockholders of the Company
approve a merger or consolidation of the Company with any other corporation
other than a merger or consolidation which would result in the Voting Securities
of the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into Voting Securities of
the surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or (iv) the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company of (in one transaction or a series of
related transactions) all or substantially all of the Company's assets.

          (b) "Claim" shall mean with respect to a Covered Event: any
threatened, pending or completed action, suit, proceeding or alternative dispute
resolution mechanism, or any hearing, inquiry or investigation that Indemnitee
in good faith believes might lead to the institution of any such action, suit,
proceeding or alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other.

          (c) References to the "Company" shall include, in addition to Applied
Imaging Corp., any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger to which Applied Imaging
Corp. (or any of its wholly owned subsidiaries) is a party which, if its
separate existence had continued, would have had power and authority to
indemnify its directors, officers, employees, agents or fiduciaries, so that if
Indemnitee is or was a director, officer, employee, agent or fiduciary of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee, agent or fiduciary of another
corporation, partnership, joint venture, employee benefit plan, trust or other
enterprise, Indemnitee shall stand in the same position under the provisions of
this Agreement with respect to the resulting or surviving corporation as
Indemnitee would have with respect to such constituent corporation if its
separate existence had continued.

          (d) "Covered Event" shall mean any event or occurrence related to the
fact that Indemnitee is or was a director, officer, employee, agent or fiduciary
of the Company, or any subsidiary of the Company, or is or was serving at the
request of the Company as a director, officer, employee, agent or fiduciary of
another corporation, partnership, joint venture, trust or other

                                      -2-
<PAGE>
 
enterprise, or by reason of any action or inaction on the part of Indemnitee
while serving in such capacity.

          (e) "Expenses" shall mean any and all expenses (including attorneys'
fees and all other costs, expenses and obligations incurred in connection with
investigating, defending, being a witness in or participating in (including on
appeal), or preparing to defend, to be a witness in or to participate in, any
action, suit, proceeding, alternative dispute resolution mechanism, hearing,
inquiry or investigation), judgments, fines, penalties and amounts paid in
settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of any Claim and any federal,
state, local or foreign taxes imposed on the Indemnitee as a result of the
actual or deemed receipt of any payments under this Agreement.

          (f) "Expense Advance" shall mean a payment to Indemnitee pursuant to
Section 3 of Expenses in advance of the settlement of or final judgement in any
action, suit, proceeding or alternative dispute resolution mechanism, hearing,
inquiry or investigation which constitutes a Claim.

          (g) "Independent Legal Counsel" shall mean an attorney or firm of
attorneys, selected in accordance with the provisions of Section 2(d) hereof,
who shall not have otherwise performed services for the Company or Indemnitee
within the last three years (other than with respect to matters concerning the
rights of Indemnitee under this Agreement, or of other Indemnitees under similar
indemnity agreements).

          (h) References to "other enterprises" shall include employee benefit
plans; references to "fines" shall include any excise taxes assessed on
Indemnitee with respect to an employee benefit plan; and references to "serving
at the request of the Company" shall include any service as a director, officer,
employee, agent or fiduciary of the Company which imposes duties on, or involves
services by, such director, officer, employee, agent or fiduciary with respect
to an employee benefit plan, its participants or its beneficiaries; and if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to
be in the interest of the participants and beneficiaries of an employee benefit
plan, Indemnitee shall be deemed to have acted in a manner "not opposed to the
best interests of the Company"  as referred to in this Agreement.

          (i) "Reviewing Party" shall mean, subject to the provisions of Section
2(d), any person or body appointed by the Board of Directors in accordance with
applicable law to review the Company's obligations hereunder and under
applicable law, which may include a member or members of the Company's Board of
Directors, Independent Legal Counsel or any other person or body not a party to
the particular Claim for which Indemnitee is seeking indemnification.

          (j) "Section" refers to a section of this Agreement unless otherwise
indicated.

          (k) "Voting Securities" shall mean any securities of the Company that
vote generally in the election of directors.

       2. Indemnification.
          --------------- 

          (a) Indemnification of Expenses.  Subject to the provisions of Section
              ---------------------------                                       
2(b) below, the Company shall indemnify Indemnitee for Expenses to the fullest
extent permitted by law if Indemnitee was or is or becomes a party to or witness
or other participant in, or is threatened to be made a party to or witness or
other participant in, any Claim (whether by reason of or arising in part out of
a Covered Event), including all interest, assessments and other charges paid or
payable in connection with or in respect of such Expenses.

          (b) Review of Indemnification Obligations. Notwithstanding the
              -------------------------------------
foregoing, in the event any Reviewing Party shall have determined (in a written
opinion, in any case in which Independent Legal Counsel is the Reviewing Party)
that Indemnitee is not entitled to be indemnified hereunder under applicable
law, (i) the Company shall have no further obligation under Section 2(a) to make
any payments to Indemnitee not made prior to such determination by such
Reviewing Party, and (ii) the Company shall be entitled to be reimbursed by
Indemnitee (who hereby agrees to reimburse the Company) for all Expenses
theretofore paid to Indemnitee to which Indemnitee is not entitled hereunder
under applicable law; provided, however, that if Indemnitee has commenced or
                      --------  -------
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee is entitled to be indemnified hereunder
under applicable law, any determination made by any Reviewing Party that
Indemnitee is not entitled to be indemnified hereunder under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expenses theretofore paid in indemnifying Indemnitee until a
final judicial determination is made with respect thereto (as to which all
rights of appeal therefrom have been exhausted or lapsed). Indemnitee's
obligation to reimburse the Company for any Expenses shall be unsecured and no
interest shall be charged thereon.

          (c) Indemnitee Rights on Unfavorable Determination; Binding Effect. If
              --------------------------------------------------------------
any Reviewing Party determines that Indemnitee substantively is not entitled to
be indemnified hereunder in whole or in part under applicable law, Indemnitee
shall have the right to commence litigation seeking an initial determination by
the court or challenging any such determination by such Reviewing Party or any
aspect thereof, including the legal or factual bases therefor, and, subject to
the provisions of Section 15, the Company hereby consents to service of process
and to appear in any such proceeding. Absent such litigation, any determination
by any Reviewing Party shall be conclusive and binding on the Company and
Indemnitee.

          (d) Selection of Reviewing Party; Change in Control. If there has not
              -----------------------------------------------
been a Change in Control, any Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), any
Reviewing Party with respect to all matters thereafter arising concerning the
rights of Indemnitee to indemnification of Expenses under this Agreement or any
other agreement or under the Company's Certificate of Incorporation or Bylaws as
now or hereafter in effect, or under any other applicable law, if desired by
Indemnitee, shall be Independent Legal Counsel selected by

                                      -4-
<PAGE>
 
Indemnitee and approved by the Company (which approval shall not be unreasonably
withheld). Such counsel, among other things, shall render its written opinion to
the Company and Indemnitee as to whether and to what extent Indemnitee would be
entitled to be indemnified hereunder under applicable law and the Company agrees
to abide by such opinion. The Company agrees to pay the reasonable fees of the
Independent Legal Counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. Notwithstanding any other provision of this Agreement, the
Company shall not be required to pay Expenses of more than one Independent Legal
Counsel in connection with all matters concerning a single Indemnitee, and such
Independent Legal Counsel shall be the Independent Legal Counsel for any or all
other Indemnitees unless (i) the employment of separate counsel by one or more
Indemnitees has been previously authorized by the Company in writing, or (ii) an
Indemnitee shall have provided to the Company a written statement that such
Indemnitee has reasonably concluded that there may be a conflict of interest
between such Indemnitee and the other Indemnitees with respect to the matters
arising under this Agreement.

          (e) Mandatory Payment of Expenses. Notwithstanding any other provision
              -----------------------------
of this Agreement other than Section 10 hereof, to the extent that Indemnitee
has been successful on the merits or otherwise, including, without limitation,
the dismissal of an action without prejudice, in defense of any Claim,
Indemnitee shall be indemnified against all Expenses incurred by Indemnitee in
connection therewith.

     3.   Expense Advances.
          ---------------- 

          (a) Obligation to Make Expense Advances.  Upon receipt of a written
              -----------------------------------
undertaking by or on behalf of the Indemnitee to repay such amounts if it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
therefore by the Company hereunder under applicable law, the Company shall make
Expense Advances to Indemnitee.

          (b) Form of Undertaking.  Any obligation to repay any Expense Advances
              -------------------
hereunder pursuant to a written undertaking by the Indemnitee shall be unsecured
and no interest shall be charged thereon.

          (c) Determination of Reasonable Expense Advances. The parties agree
              --------------------------------------------
that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of Indemnitees'
counsel as being reasonable shall be presumed conclusively to be reasonable.

                                      -5-
<PAGE>
 
        4. Procedures for Indemnification and Expense Advances.
           --------------------------------------------------- 

          (a) Timing of Payments.  All payments of Expenses (including without
              ------------------
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than thirty (30) business days after such written
demand by Indemnitee is presented to the Company, except in the case of Expense
Advances, which shall be made no later than ten (10) business days after such
written demand by Indemnitee is presented to the Company.

          (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition
              --------------------------------
precedent to Indemnitee's right to be indemnified or Indemnitee's right to
receive Expense Advances under this Agreement, give the Company notice in
writing as soon as practicable of any Claim made against Indemnitee for which
indemnification will or could be sought under this Agreement. Notice to the
Company shall be directed to the Chief Executive Officer of the Company at the
address shown on the signature page of this Agreement (or such other address as
the Company shall designate in writing to Indemnitee). In addition, Indemnitee
shall give the Company such information and cooperation as it may reasonably
require and as shall be within Indemnitee's power.

          (c) No Presumptions; Burden of Proof. For purposes of this Agreement,
              --------------------------------
the termination of any Claim by judgment, order, settlement (whether with or
without court approval) or conviction, or upon a plea of nolo contendere, or its
                                                         ---------------
equivalent, shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has
determined that indemnification is not permitted by this Agreement or applicable
law. In addition, neither the failure of any Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by any
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
this Agreement under applicable law, shall be a defense to Indemnitee's claim or
create a presumption that Indemnitee has not met any particular standard of
conduct or did not have any particular belief. In connection with any
determination by any Reviewing Party or otherwise as to whether the Indemnitee
is entitled to be indemnified hereunder under applicable law, the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.

          (d) Notice to Insurers. If, at the time of the receipt by the Company
              ------------------
of a notice of a Claim pursuant to Section 4(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee, all amounts payable as a result of such Claim in
accordance with the terms of such policies.

                                      -6-
<PAGE>
 
          (e) Selection of Counsel.  In the event the Company shall be obligated
              --------------------
hereunder to provide indemnification for or make any Expense Advances with
respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by Indemnitee
(which approval shall not be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election to do so.  After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees or expenses of separate counsel subsequently retained by
or on behalf of Indemnitee with respect to the same Claim; provided that, (i)
Indemnitee shall have the right to employ Indemnitee's separate counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of separate
counsel by Indemnitee has been previously authorized by the Company, (B)
Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense,
or (C) the Company shall not continue to retain such counsel to defend such
Claim, then the fees and expenses of Indemnitee's separate counsel shall be
Expenses for which Indemnitee may receive indemnification or Expense Advances
hereunder.

       5. Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a) Scope. The Company hereby agrees to indemnify the Indemnitee to
              -----
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its board of directors or an officer, employee, agent or fiduciary, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change. In the event of any
change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, such change, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 10(a) hereof.

          (b) Nonexclusivity.  The indemnification and the payment of Expense
              --------------
Advances provided by this Agreement shall be in addition to any rights to which
Indemnitee may be entitled under the Company's Certificate of Incorporation, its
Bylaws, any other agreement, any vote of stockholders or disinterested
directors, the General Corporation Law of the State of Delaware, or otherwise.
The indemnification and the payment of Expense Advances provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken
while serving in an indemnified capacity even though subsequent thereto
Indemnitee may have ceased to serve in such capacity.

                                      -7-
<PAGE>
 
       6. No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.

       7. Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

       8. Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances, federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents or
fiduciaries under this Agreement or otherwise.  Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

       9. Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

       10. Exceptions.  Notwithstanding any other provision of this Agreement,
           ----------
the Company shall not be obligated pursuant to the terms of this Agreement:

          (a) Excluded Action or Omissions. To indemnify or make Expense
              ----------------------------
Advances to Indemnitee with respect to Claims arising out of acts, omissions or
transactions for which Indemnitee is prohibited from receiving indemnification
under applicable law.

          (b) Claims Initiated by Indemnitee. To indemnify or make Expense
              ------------------------------
Advances to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, counterclaim or crossclaim, except (i)
with respect to actions or proceedings brought to establish or enforce a right
to indemnification under this Agreement or any other agreement or insurance
policy or under the Company's Certificate of Incorporation or Bylaws now or
hereafter in effect relating to Claims for Covered Events, (ii) in specific
cases if the Board of Directors has approved the initiation or bringing of such
Claim, or (iii) as otherwise required under Section 145 of the Delaware General
Corporation Law, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, Expense Advances, or insurance recovery, as
the case may be.

                                      -8-
<PAGE>
 
          (c) Lack of Good Faith. To indemnify Indemnitee for any Expenses
              ------------------
incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each of
the material assertions made by the Indemnitee as a basis for such action was
not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this Agreement, if a court having jurisdiction
over such action determines as provided in Section 13 that each of the material
defenses asserted by Indemnitee in such action was made in bad faith or was
frivolous.

          (d) Claims Under Section 16(b). To indemnify Indemnitee for Expenses
              --------------------------
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

       11. Counterparts.  This Agreement may be executed in one or more
           ------------                                                
counterparts, each of which shall constitute an original.

       12. Binding Effect; Successors and Assigns.  This Agreement shall be
           --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives.  The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent or fiduciary (as applicable) of the Company
or of any other enterprise at the Company's request.

       13. Expenses Incurred in Action Relating to Enforcement or
           ------------------------------------------------------  
Interpretation. In the event that any action is instituted by Indemnitee under
- --------------
this Agreement or under any liability insurance policies maintained by the
Company to enforce or interpret any of the terms hereof or thereof, Indemnitee
shall be entitled to be indemnified for all Expenses incurred by Indemnitee with
respect to such action (including without limitation attorneys' fees),
regardless of whether Indemnitee is ultimately successful in such action, unless
as a part of such action a court having jurisdiction over such action makes a
final judicial determination (as to which all rights of appeal therefrom have
been exhausted or lapsed) that each of the material assertions made by
Indemnitee as a basis for such action was not made in good faith or was
frivolous; provided, however, that until such final judicial determination is
made, Indemnitee shall be entitled under Section 3 to receive payment of Expense
Advances hereunder with respect to such action. In the event of an action
instituted by or in the name of the Company under this Agreement to enforce or
interpret any of the terms of this Agreement, Indemnitee shall be entitled to be
indemnified for all Expenses incurred by Indemnitee in defense of such action
(including without limitation costs and expenses incurred with respect to
Indemnitee's

                                      -9-
<PAGE>
 
counterclaims and cross-claims made in such action), unless as a part of such
action a court having jurisdiction over such action makes a final judicial
determination (as to which all rights of appeal therefrom have been exhausted or
lapsed) that each of the material defenses asserted by Indemnitee in such action
was made in bad faith or was frivolous; provided, however, that until such final
judicial determination is made, Indemnitee shall be entitled under Section 3 to
receive payment of Expense Advances hereunder with respect to such action.

       14. Period of Limitations.  No legal action shall be brought and no cause
           ---------------------
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two year period; provided, however, that if any shorter
                                    --------  -------                     
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

       15. Notice. All notices, requests, demands and other communications under
           ------
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked. Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

       16. Consent to Jurisdiction.  The Company and Indemnitee each hereby
           -----------------------
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

       17. Severability.  The provisions of this Agreement shall be severable in
           ------------
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

       18. Choice of Law. This Agreement, and all rights, remedies, liabilities,
           -------------
powers and duties of the parties to this Agreement, shall be governed by and
construed in accordance with the laws of the State of Delaware as applied to
contracts between Delaware residents entered into and to be performed entirely
in the State of Delaware without regard to principles of conflicts of laws.

                                      -10-
<PAGE>
 
       19. Subrogation.  In the event of payment under this Agreement, the
           -----------
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

       20. Amendment and Termination. No amendment, modification, termination or
           -------------------------
cancellation of this Agreement shall be effective unless it is in writing signed
by both the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed to be or shall constitute a waiver of any other provisions
hereof (whether or not similar), nor shall such waiver constitute a continuing
waiver.

       21. Integration and Entire Agreement.  This Agreement sets forth the
           --------------------------------
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

       22. No Construction as Employment Agreement.  Nothing contained in this
           ---------------------------------------
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or affiliated entities.

     IN WITNESS WHEREOF, the parties hereto have executed this Indemnification
Agreement as of the date first above written.

               AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT


          This Agreement is made as of July 28, 1995 by and between Applied

and the purchasers of Series C Preferred Stock, Series D Preferred Stock, Series

        b.     Company Registration.
               -------------------- 

          i.        Except as provided elsewhere in this Section 1, if, at any
               time or from time to time, Applied Imaging shall determine to
               register any of its securities for its own account, other than
               (i) a registration relating to employee benefit 
<PAGE>
 
               plans, or (ii) a registration relating to a Commission Rule 145
               transaction, Applied Imaging will:

               (1)    promptly give notice thereof to each Holder; and

               (2)    include in such registration (and any related
                    qualification or other compliance under Blue Sky laws), and
                    in any underwriting involved therein, except as set forth in
                    Section 1.2.2 below, all the Registrable Securities held of
                    record (or issuable upon conversion of securities held of
                    record) by, and specified in a written notice or notices
                    from, any Holder or Holders received by Applied Imaging
                    within thirty (30) days after the date of such written
                    notice from Applied Imaging.

          ii.       If the registration of which Applied Imaging gives notice is
               for a registered public offering involving an underwriting,
               Applied Imaging shall so advise the Holder(s) as a part of the
               written notice from Applied Imaging given pursuant to Section
               1.2.1(i).  In such event the right of any Holder to registration
               pursuant to this Section 1.2 shall be conditioned upon such
               Holder's participation in such underwriting and the inclusion of
               such Holder's Registrable Securities in the underwriting to the
               extent provided herein.  All Holders proposing to distribute
               their securities through such underwriting shall (together with
               Applied Imaging and the other Holders distributing their
               securities through such underwriting) enter into an underwriting
               agreement in customary form with the underwriter or underwriters
               selected for such underwriting by Applied Imaging.
               Notwithstanding any other provision of this Section 1.2, if the
               managing underwriter determines that marketing factors require a
               limitation of the number of shares to be underwritten, the
               managing underwriter may in its discretion exclude some or all of
               the Registrable Securities from such registration and
               underwriting; provided, however, that the number of shares of
               Registrable Securities to be included in such underwriting shall
               not be reduced unless all securities held by other holders are
               first entirely excluded from such underwriting.  In the event of
               any such reduction, Applied Imaging shall so advise all Holders,
               and the number of shares of Registrable Securities which may be
               included in the registration and underwriting shall be allocated
               by Applied Imaging among all of the Holders thereof at the time
               of filing the registration statement in proportion, as nearly as
               practicable, to the respective amounts of Registrable Securities
               held by such Holders at the time of filing the Registration
               Statement and no Registrable Securities excluded from the
               underwriting by reason of the underwriter's marketing limitation
               shall be included in such registration.  If any Holder dis
               approves of the terms of any such underwriting, it may elect to
               withdraw therefrom by notice to Applied Imaging and the managing
               underwriter.  Any securities excluded or withdrawn from such
               underwriting shall be withdrawn from such registration.

        c.     Request for Registration. If at any time after the earlier of (i)
               ------------------------
           August 31, 1996 or (ii) the date which is six (6) months from the
           closing of Applied Imaging's initial underwritten registered public
           offering (pursuant to a registration statement on Form S-1 or any
           successor form), Applied Imaging shall receive a written request
           (specifying that such request is being made pursuant to this Section
           1.3) from the Holders of a majority of the Registrable Securities
           ("Initiating Holders") that Applied Imaging file a registration
           statement under the Securities Act (and any related qualification or
           other compliance under Blue Sky laws) covering the registration of
           Registrable Securities held of record (or issuable upon conversion of
           securities held of record) by such Holders equal to the greater of
           (i) fifty percent (50%) or more of the total Registrable Securities
           (assuming conversion of all securities convertible into Registrable
           Securities), or (ii) an amount of Registrable Securities which would
           be valued at $3,500,000 or more based on the expected price to the
           public in the offering being registered, then Applied Imaging shall
           promptly notify all other Holders of such request and, as soon as
           practicable, use its best efforts to effect such registration,
           qualification or compliance (including, without limitation,
           appropriate qualification under applicable regulations issued under
           the Securities Act and any other governmental requirements or
           regulations) as may be so requested and as would permit or facilitate
           the sale and distribution of all or such portion of such Registrable
           Securities as are specified in such request, together with all or
           such portion of the Registrable Securities of any Holder or Holders
           joining in such request as are specified in a written request
           received by Applied Imaging within twenty (20) days after receipt of
           such written notice from Applied Imaging; provided, however, that
           Applied Imaging shall not be obligated to take any action to effect
           any such registration, qualification or compliance pursuant to this
           Section 1.3 in any particular jurisdiction in which Applied Imaging
           would be required to execute a general consent to service of process
           in effecting such registration, qualification or compliance unless
           Applied Imaging is already generally subject to service in such
           jurisdiction and except as may be required by the Securities Act.

           i.           Notwithstanding the foregoing, (i) Applied Imaging shall
                not be obligated to effect a registration pursuant to this
                Section 1.3 during the period starting with the date ninety (90)
                days prior to Applied Imaging's estimated date of filing of, and
                ending on a date six (6) months following the effective date of,
                a registration statement pertaining to an underwritten public
                offering of its securities (other than a registration relating
                to employee benefit plans or to a Commission Rule 145
                transaction), provided that Applied Imaging is actively
                employing in good faith all reasonable efforts to cause such
                registration statement to become effective and that Applied
                Imaging's estimate of the date of filing such registration
                statement is made in good faith; and (ii) if Applied Imaging
                shall furnish to such Holders a certificate signed by the
                President or the Chairman of the Board of Applied Imaging
                stating that in the good faith judgment of the Board of
                Directors it would be seriously
<PAGE>
 
               detrimental to Applied Imaging or its shareholders for a
               registration statement to be filed in the near future, then
               Applied Imaging's obligation to use its best efforts to file a
               registration statement shall be deferred for a period not to
               exceed six (6) months.

           ii.     Applied Imaging shall be obligated to effect only one
               registration pursuant to this Section 1.3.

           iii.    In the event that a registration requested pursuant to
               this Section 1.3 is for a registered public offering involving an
               underwriting, Applied Imaging shall so advise the Holders as part
               of the notice given pursuant to this Section 1.3. In such event,
               the right of any Holder to registration pursuant to this Section
               1.3 shall be conditioned upon such Holder's participation in the
               underwriting arrangements required by this Section 1.3, and the
               inclusion of such Holder's Registrable Securities in the
               underwriting to the extent requested shall be limited to the
               extent provided herein. Applied Imaging shall (together with all
               Holders proposing to distribute their securities through such
               underwriting) enter into an underwriting agreement in customary
               form with a managing underwriter selected for such underwriting
               by a majority in interest of the Initiating Holders, but the
               managing underwriter and the underwriting agreement shall be
               subject to Applied Imaging's reasonable approval. Notwithstanding
               any other provision of this Section 1.3, if the managing
               underwriter advises the Initiating Holders and Applied Imaging in
               writing that marketing factors require a limitation of the number
               of shares to be underwritten, then Applied Imaging shall so
               advise all Holders electing to participate in the registration
               and underwriting and the number of shares of Registrable
               Securities that may be included in the registration and
               underwriting shall be allocated among all such Holders by Applied
               Imaging in proportion, as nearly as practicable, to the
               respective amounts of Registrable Securities held by such Holders
               at the time of filing the registration statement. To the extent
               any of such Holders elects not to sell the full number of shares
               it is entitled to sell pursuant to the preceding sentence, the
               other such Holders' respective rights to participate in the
               registration and underwriting shall be increased pro rata by a
               corresponding number of shares. No Registrable Securities
               excluded from the underwriting by reason of the managing
               underwriter's marketing limitation shall be included in such
               registration. To facilitate the allocation of shares in
               accordance with the above provision, Applied Imaging may round
               the number of shares allocated to any Holder to the nearest 100
               shares. If any Holder of Registrable Securities disapproves of
               the terms of the underwriting, it may elect to withdraw therefrom
               by written notice to Applied Imaging, the managing underwriter
               and the initiating Holders. In the event that such underwriting
               represents the initial under written public offering of Applied
               Imaging's securities, any securities excluded or withdrawn from
               such under-
<PAGE>
 
               writing shall be withdrawn from such registration and shall not
               be transferred in a public distribution prior to four (4) months
               after the effective date of such registration statement, or such
               other shorter period of time as the managing underwriter may
               permit in writing, but, however, subject to any longer period
               that may be required pursuant to Section 1.10.

        d.     Registration on Form S-3.
               ------------------------ 

          i.        If any Holder or Holders holding in the aggregate not less
               than 5% of the then outstanding Registrable Securities request
               that Applied Imaging file a registration statement on Form S-3
               (or any successor form to Form S-3) for a public offering of
               shares of the Registrable Securities the reasonably anticipated
               aggregate price to the public of which, net of underwriting dis
               counts and commissions, would exceed $1,000,000 and Applied
               Imaging is a registrant entitled to use Form S-3 to register the
               Registrable Securities for such an offering, Applied Imaging
               shall use its best efforts to cause such Registrable Securities
               to be registered for the offering on such form and to cause such
               Registrable Securities to be qualified in such jurisdictions as
               the Holder or Holders may reasonably request; provided, however,
               that Applied Imaging shall not be required to effect more than
               one registration pursuant to this Section 1.4 in any twelve month
               period or in excess of two registrations under this Section 1.4.
               The substantive provisions of Section 1.3.3 shall be applicable
               to each registration initiated under this Section 1.4.

          ii.       Notwithstanding the foregoing, Applied Imaging shall not be
               obligated to take any action pursuant to this Section 1.4:  (i)
               in any particular jurisdiction in which Applied Imaging would be
               required to execute a general consent to service of process in
               effecting such registration, qualification or compliance unless
               Applied Imaging is already subject to service in such
               jurisdiction and except as may be required by the Securities Act;
               (ii) if Applied Imaging, within ten (10) days of the receipt of
               the request of the initiating Holders, gives notice of its bona
               fide intention to effect the filing of a registration statement
               with the Commission within ninety (90) days of receipt of such
               request (other than with respect to a registration statement
               relating to a Rule 145 transaction, an offering solely to
               employees or any other registration which is not appropriate for
               the registration of Registrable Securities); (iii) during the
               period starting with the date sixty (60) days prior to Applied
               Imaging's estimated date of filing of, and ending on the date six
               (6) months immediately following, the effective date of any
               registration statement pertain  ing to securities of Applied
               Imaging (other than a registration of securities in a Rule 145
               transaction or with respect to an employee benefit plan),
               provided that Applied Imaging is actively employing in good faith
               all reasonable efforts to cause such registration statement to
               become effective; or (iv) if Applied Imaging shall furnish to
               such 
<PAGE>
 
               Holder a certificate signed by the President of Applied Imaging
               stating that in the good faith judgment of the Board of Directors
               it would be detrimental to Applied Imaging or its shareholders
               for registration statements to be filed at such time, then
               Applied Imaging's obligation to use its best efforts to file a
               registration statement shall be deferred for a period not to
               exceed 120 days from the receipt of the request to file such
               registration by such Holder.

        e.     Expenses of Registration.
               ------------------------ 

          i.        All Registration Expenses incurred in connection with any
               registration, qualification or compliance pursuant to Section 1.2
               above shall be borne by Applied Imaging; and all Selling Expenses
               related to securities registered by the Holder(s) shall be borne
               by the Holder(s) of such securities pro rata on the basis of the
               number of shares so registered; provided, however, that (anything
               in this Section 1 to the contrary notwithstanding with respect to
               the bearing of expenses) if any jurisdiction in which the
               securities shall be qualified shall require that expenses
               incurred in connection with the qualification of the securities
               in that jurisdiction be borne by selling shareholders, then such
               expenses shall be payable by the selling shareholders pro rata,
               to the extent required by such jurisdiction.

          ii.       All Registration Expenses incurred in connection with one
               registration pursuant to Section 1.3 shall be paid by Applied
               Imaging and all Selling Expenses shall be paid by the Holders pro
               rata in accordance with the number of Registrable Securities
               included in such registration.

          iii.      All Registration Expenses incurred in connection with two
               registrations pursuant to Section 1.4 shall be paid by Applied
               Imaging and all Selling Expenses shall be paid by the Holders pro
               rata in accordance with the number of Registrable Securities
               included in such registration.

        f.     Registration Procedures.  In the case of each registration,
               -----------------------                                    
          qualification or compliance effected pursuant to this Section 1,
          Applied Imaging will keep each Holder advised in writing as to the
          initiation of each registration, qualification and compliance and as
          to the completion thereof.  At its expense, Applied Imaging will with
          all deliberate speed:

          i.        Prepare and file with the Commission a registration
               statement with respect to the Registrable Securities to be
               registered and use its best efforts to cause such registration
               statement to become and remain effective for at least ninety (90)
               days;
<PAGE>
 
          ii.       Furnish to the Holders participating in such registration
               and to the underwriters of the Registrable Securities being
               registered such reasonable number of copies of the registration
               statement, preliminary prospectus, final prospectus and such
               other documents as such underwriters may reasonably request in
               order to facilitate the public offering of such securities;

          iii.      Prepare and file with the Commission such amendments and
               supplements to such registration statement and the prospectus
               used in connection with such registration statement as may be
               necessary to comply with the provisions of the Securities Act
               with respect to the disposition of all securities covered by such
               registration statement.

        g.     Indemnification.
               --------------- 

          i.        To the extent permitted by law, Applied Imaging will
               indemnify and hold harmless each Holder, each of its officers and
               directors and partners and such Holder's legal counsel and
               independent accountants, and each person controlling such Holder
               within the meaning of Section 15 of the Securities Act, and each
               underwriter, if any, and each person who controls any underwriter
               within the meaning of Section 15 of the Securities Act, against
               all expenses, claims, losses, damages and liabilities (or actions
               in respect thereof), including any of the foregoing incurred in
               settlement of any litigation, commenced or threatened, with
               respect to registration, qualification or compliance which has
               been effected pursuant to this Section 1, (i) arising out of or
               based on any untrue statement (or alleged untrue statement) of a
               material fact contained in any registration statement,
               prospectus, offering circular or other document (including any
               related registration statement, notification and the like) or any
               amendment or supplement thereto, incident to any such
               registration, qualification or compliance, or (ii) based on any
               omission (or alleged omission) to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein, in light of the circumstances in which they were made,
               not misleading, or (iii) any violation by Applied Imaging of any
               rule or regulation promulgated under the Securities Act
               applicable to Applied Imaging and relating to action or inaction
               required of Applied Imaging in connection with any such
               registration, qualification or compliance. Applied Imaging will
               reimburse such Holder, each of its officers, directors and
               partners and such Holder's legal counsel and independent
               accountants, and each person controlling such Holder within the
               meaning of Section 15 of the Securities Act, each such
               underwriter and each such person who controls any such
               underwriter within the meaning of Section 15 of the Securities
               Act, for any legal and any other expenses reasonably incurred in
               connection with investigating, preparing or defending any such
               claim, loss, damage, liability or action; provided that Applied
               Imaging will not be liable under this Section 1.7.1 to the
<PAGE>
 
               extent that any such claim, loss, damage, liability or expense
               arises out of, or is based on, any untrue statement or omission
               or alleged untrue statement or omission made in reliance upon and
               in conformity with written information furnished to Applied
               Imaging by any such Holder or underwriter.

          ii.       Notwithstanding any other provision of this Section 1, the
               obligation of the Applied Imaging to include the Registrable
               Securities of any Holder in any registration, and any related
               qualification or compliance, shall be conditioned upon such
               Holder entering into an indemnification agreement in customary
               form with Applied Imaging and any underwriter(s) for the
               securities to be registered, satisfactory to Applied Imaging and
               such under  writer(s), which shall provide for indemnification by
               such Holder, to the extent permitted by law, of Applied Imaging,
               each of its directors and officers and its legal counsel and
               independent accountants, each underwriter, if any, of Applied
               Imaging's securities covered by such a registration statement,
               each person who controls Applied Imaging or such underwriter
               within the meaning of Section 15 of the Securities Act, and each
               other such Holder, each of its officers and directors and
               partners and such other Holder's legal counsel and independent
               accountants, and each person controlling such other Holder within
               the meaning of Section 15 of the Securities Act, against all
               claims, losses, damages and liabilities (or actions in respect
               thereof) arising out of or based on any untrue statement (or
               alleged untrue statement) of a material fact contained in any
               such registration statement, prospectus, offering circular and
               other document (including any registration statement,
               notification and the like), or any omission (or alleged omission)
               to state therein a material fact required to be stated therein or
               necessary to make the statements therein, in light of the
               circumstances in which they were made, not misleading, in each
               case to the extent, but only to the extent, that such untrue
               statement (or alleged untrue statement) or omission (or alleged
               omission) is made in such registration statement, prospectus,
               offering circular or other document in reliance upon and in
               conformity with written information furnished to Applied Imaging
               by an instrument duly executed by such Holder and stated to be
               specifically for use therein.  Notwithstanding the foregoing, the
               liability of the Holders under this Section 1.7.2 shall be
               limited to an amount equal to the gross offering proceeds of the
               registration.

          iii.      Each party entitled to indemnification under Section 1.7.1
               (the "Indemnified Party") shall give notice to Applied Imaging
               promptly after such Indemnified Party has actual knowledge of any
               claim as to which indemnity may be sought, and shall permit
               Applied Imaging to assume the defense of any such claim or any
               litigation resulting therefrom, provided that counsel for Applied
               Imaging, who shall conduct the defense of such claim or
               litigation, shall be approved of by the Indemnified Party (which
               approval shall not be 
<PAGE>
 
               unreasonably withheld), and the Indemnified Party may participate
               in such defense at such party's expense, and provided further
               that the failure of any Indemnified Party to give notice as
               provided herein shall not relieve Applied Imaging of its
               obligations under this Section 1. In the defense of any such
               claim or litigation, Applied Imaging shall not, except with the
               consent of each Indemnified Party, consent to entry of any
               judgment or enter into any settlement which does not include as
               an unconditional term thereof the giving by the claimant or
               plaintiff to such Indemnified Party of a release from all
               liability in respect to such claim or litigation.

        h.     Information by Holder.  The Holder(s) of Registrable Securities
               ---------------------                                          
          included in any registration shall furnish to Applied Imaging such
          information regarding such Holder(s) and the distribution proposed by
          such Holder(s) as Applied Imaging may reasonably request in writing
          and as shall be required in connection with any registration,
          qualification or compliance referred to in this Section 1.

        i.     Termination of Applied Imaging's Obligations.  Applied Imaging
               --------------------------------------------                  
          shall have no obligation pursuant to Sections 1.2, 1.3 and 1.4 with
          respect to any request or requests made by any Holder more than five
          (5) years after the effective date of Applied Imaging's first
          registered and underwritten public offering of securities for its own
          account or for the account of Holders pursuant to Section 1.3.

        j.     "Lock-Up" Agreement.  Until termination of Applied Imaging's
               -------------------                                         
          obligation as provided under Section 1.9 above, each Holder hereby
          agrees that it shall not

               (1)   during the first six (6) months following the effective
                    date of the registration statement filed under the
                    Securities Act covering Applied Imaging's initial
                    underwritten offering of its securities to the general
                    public for its own account, nor

               (2)   following the effective date of any registration statement
                    filed by Applied Imaging under the Securities Act (including
                    the one covering its initial underwritten offering of its
                    securities to the general public for its own account), to
                    the extent and for the period consented to in writing by
                    Holders holding a majority of the Registrable Securities
                    (assuming, for this purpose, conversion of all outstanding
                    shares of the Stock) held by all Holders, sell, make any
                    short sale of, loan, grant any option for the purchase of,
                    or otherwise transfer or dispose of (other than to donees
                    who agree to be similarly bound) any Applied Imaging
                    securities, without the prior written consent of Applied
                    Imaging or the managing underwriter in such offering, as the
                    case may be.  Applied Imaging may place an appropriate
                    legend on all certificates for Registrable Securities and
                    the securities convertible into Registrable 

<PAGE>
 
                    Securities referring to the restrictions on transfer set
                    forth in this Section 1.
 
The obligations of the Holders under this Section 1.10 are subject to the
agreement by each officer and director of Applied Imaging that owns stock of
Applied Imaging and each holder of at least one percent (1%) of Applied
Imaging's outstanding voting equity securities to abide by the foregoing
restrictions.

1.        Amendment to Prior Agreement.  The Registration Rights Agreement dated
          ----------------------------                                          
     August 24, 1993 (the "Prior Agreement") is hereby amended and restated in
     its entirety to read as set forth herein.  The foregoing amendment shall be
     effective upon execution of this Agreement by the Company and the holders
     of a majority of the Registrable Securities (as such term is defined in the
     Prior Agreement).

2.        Miscellaneous.
          ------------- 

     a.        Waivers and Amendments.  With the written consent of Applied
               ----------------------                                      
          Imaging and the Holders of more than 50% of the Registrable
          Securities, the obligations of Applied Imaging and the rights of the
          Holders under this Agreement may be waived (either generally or in a
          particular instance, either retroactively or prospectively and either
          for a specified period of time or indefinitely), and with the same
          consent Applied Imaging, when authorized by resolution of its Board of
          Directors, may enter into a supplementary agreement for the purpose of
          adding any provisions to or changing in any manner or eliminating any
          of the provisions of this Agreement; provided, however, that no such
          waiver or supplemental agreement shall reduce the aforesaid percentage
          of Registrable Securities, the Holders of which are required to
          consent to any waiver or supplemental agreement without the consent of
          the Holders of all of the Registrable Securities.  Neither this
          Agreement nor any provisions hereof may be changed, waived, discharged
          or terminated orally, but only by a signed statement in writing.  Any
          amendment, waiver or supplementary agreement effected in accordance
          with this paragraph shall be binding upon each Holder of any
          Registrable Securities then outstanding, each future Holder of all
          such Registrable Securities and Applied Imaging.

     b.        Governing Law.  This Agreement shall be governed in all respects
               -------------                                                   
          by the laws of the State of California as such laws are applied to
          agreements between California residents entered into and to be
          performed entirely within California.

     c.        Successors and Assigns.  Except as otherwise expressly provided
               ----------------------                                         
          herein, the provisions hereof shall inure to the benefit of, and be
          binding upon, the successors, assigns, heirs, executors and
          administrators of the parties hereto.

          Holder shall have furnished the Company in writing, or, until any such
          Holder so furnishes an address to the Company, then to and at the
          address of the last holder of such securities who has so furnished an
          address to the Company, or (b) if to the Company, at 2340A Walsh
          Avenue, Building F, Santa Clara, CA 95051, or at such other address as
          the Company shall have furnished to the Holders in writing.

     Each such notice or other communication shall for all purposes of this
Agreement be treated as effective or having been given when delivered if
